1 Changes with Apache 2.0.23-dev
3 *) Add a single listener/multiple worker MPM. This MPM is
4 definately not fully correct, but it allows us to solve many
5 of the problems that exist in the threaded MPM. This is a
6 modified version of the threaded MPM. [Ryan Bloom]
8 *) Improve content generation throughout Apache, providing closer
9 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
10 Transitional specifications. [William Rowe]
12 Changes with Apache 2.0.22
14 *) Fix a problem where the threaded MPM stalls after restarts or
15 segfaults. Also prevent multiple active processes from using
16 the same scoreboard slot. [Greg Ames]
18 *) Apache/Win32 now fills in the service description with Apache's
19 server version string, including loaded and advertised modules.
22 *) Improved support for the Win32 build, to recover gracefully from
23 missing apr or apr-util directories or the awk interpreter,
24 create the proper cgi-bin examples, including a test-cgi.bat, and
25 fix the perl shebang line for printenv.pl, when installing from
26 the build environment. [William Rowe]
28 *) Fix a segfault in threaded.c caused by passing uninitialized
29 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
31 *) Use new APR number conversion functions to reduce CPU consumption
32 when setting the content length, and in mod_log_config.
35 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
36 where HEAD response headers were being repeated twice for
37 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
38 problem in the http_header filter was exposed by the recent rewrite
39 of the content_length filter. [Taketo Kabe, Bill Stoddard]
41 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
42 restarts. A garbage pointer to a vhost's server_rec from the
43 previous generation was being left around under certain
44 conditions. [Greg Ames]
46 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
47 used to appear as '(none', without the closing paren.
48 [Günter Knauf <eflash@gmx.net>]
50 *) Improve the exports generating awk script. In the past, we had
51 work around problems in the awk script by avoiding some #if and
52 #ifdefs. This has bitten us many times in generating the exports.c
53 file. This improvement allows corrects the header file parsing.
54 [Sander Striker <striker@apache.org>]
56 Changes with Apache 2.0.21
58 *) Resolve the Win32 htpasswd bug, where a file that existed would be
59 overwritten, regardless of the -c flag.
60 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
62 *) Introduce connection sub-pools into ab. Truncating the lifetime
63 of these allocations means that ab no longer perpetually grows
64 its working set, running out of memory on large request attempts.
67 *) Make scoreboard creation a hook. This allows management
68 modules to have access to the scoreboard at the time that it is
69 created, and at every restart request.
70 [Cody Sherr <csherr@covalent.net>]
72 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
73 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
74 daemon index actually used in the scoreboard. I also
75 updated the pertinent calls. [Paul J. Reder]
77 *) Win32: Prevent listening sockets from being inherited by
78 the Apache child process, CGI scripts, rotatelog process
79 etc. If the Apache child process segfaults, any processes
80 that the child started are not reaped. Prior to this fix,
81 these processes inherited the listening sockets which sometimes
82 prevented the restarted Apache child process from accepting
83 connections (ie, the server would hang).
86 *) Provide vhost and request strings when ExtendedStatus is on.
89 *) Fix some issues with the pod and prefork: check the pod *after*
90 processing a connection so that a server processing a time-
91 consuming request bails out as soon as practical; when the
92 parent process wakes up a server process via connect(), use an
93 APR timeout on the connect() so that we don't hang for a long
94 time if there aren't server processes around to do accept().
95 [Jeff Trawick, Greg Ames]
97 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
98 spends a lot of time in apr_table_get calls. Using the default
99 httpd.conf, the tables for languages and charsets are somewhat
100 large, so the time spent scanning them on each request is
101 significant. Replacing the tables with hash tables provides
102 a nice speedup. [Brian Pane <bpane@pacbell.net>]
104 *) Add two functions to allow modules to access random parts of the
105 scoreboard. This allows modules compiled for one MPM to access the
106 scoreboard, even if it the server was compiled for another MPM.
107 [Harrie Hazewinkel <harrie@covalent.net>]
109 Changes with Apache 2.0.20
111 *) Fix problem in content-length filter where the filter would
112 buffer all the output from a CGI before sending any bytes
113 down the filter stack to the network. This problem would cause
114 significant memory consumption if the CGIs generated
115 lots of bytes. [Bill Stoddard]
117 *) Get non-blocking CGI pipe reads working with the bucket brigades.
120 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
123 *) Fix a bug in the threaded MPM that would cause it to kill off all
124 workers immediately after starting if the number of workers started
125 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
127 Changes with Apache 2.0.19
129 *) Fix problem with threaded MPM. The problem was that if each child
130 process was busy serving a single long-lived request and the server
131 was sent a graceful restart signal, the server would stop serving
132 requests. This would happen because each child process would wait to
133 die until the last thread was done, and the parent wouldn't spawn any
134 new children until a process died. Now, the parent looks at the fact
135 that the children are dying gracefully, and starts new children.
136 Those new children only start enough threads to compliment the number
137 of threads in the other child process that shares the same spot in
138 the scoreboard. In this way, we make sure to never go over
139 MaxClients. [Ryan Bloom]
141 *) modified mod_negotiation and mod_autoindex to speed up by almost a
142 factor of two on apr_dir_read()-enhanced platforms, such as Win32
143 and OS2, by calling ap_sub_request_lookup_dirent() with the results
144 already provided by apr_dir_read(). [William Rowe]
146 *) mod_file_cache is now more robust to filtering and serves requests
147 slightly more efficiently. [Cliff Woolley]
149 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
150 Module was calling ap_rwrite() followed by ap_rflush() but the
151 served content was not being displayed in the browser. Inspection
152 of the output stream revealed that the first data chunk was
153 missing the trailing CRLF required by the RFC. [Bill Stoddard]
155 *) apxs no longer generates ap_send_http_header() in the example handler
157 *) Fix an ab problem which could cause a divide-by-zero exception
158 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
159 [Ian Holsman <ianh@cnet.com>]
161 *) Solve case-insensitive platforms' confusion about negotiated
162 filenames, allowing files of differnt case to match in choosing
163 the document to serve. [William Rowe]
165 *) Fix brokenness when ThreadsPerChild is higher than the built-in
166 limit. We left ap_threads_per_child at the higher value which
167 led to segfaults when doing certain scoreboard operations.
170 *) Fix seg faults and/or missing output from mod_include. The
171 default_handler was using the subrequest pool for files and
172 MMAPs, even though the associated APR structures typically
173 live longer than the subrequest. [Greg Ames]
175 *) Extend mod_setenvif to support specifying regular expressions
176 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
177 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
178 will cause HAVE_TS to be set if any of the request headers begins
179 with "TS" and has a value that begins with any character in the
180 set [a-z]. [Bill Stoddard]
182 *) httpd children now re-bind themselves to a random CPU on
183 multiprocessor systems on AIX via bindprocessor() in 2.0.
184 [Victor J. Orlikowski]
186 *) Fix htdigest. It would go into a loop in getline when adding
187 a second user. [Bill Stoddard]
189 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
191 *) Automatically generate httpd.exp for AIX.
192 DSOs now work again on AIX in 2.0
193 [Victor J. Orlikowski]
195 *) Add a new request hook, error_log. This phase allows modules
196 to act on the error log string _after_ it has been written
197 to the error log. The goal for this hook is to allow monitoring
198 modules to send the error string to the monitoring agent.
201 *) Modify mod_echo to make it use filters for input and output.
202 [Ryan Morgan <rmorgan@covalent.net>]
204 *) Extend mod_headers to support conditional driven Header
205 add, append and set. Use SetEnvIf to set an envar and conditionally
206 add/append/set headers based on this envar thusly:
208 SetEnvIf TSMyHeader value HAVE_TSMyHeader
209 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
211 If the request contains header "TSMyHeader: value" then header
212 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
215 *) Extend mod_headers to support using format specifiers on Header
216 add, append and set header values. Two format specifiers are supported:
218 %t - reports, in UTC microseconds since the epoch, when the
219 request was received.
221 %D - reports the time, in microseconds, between when the request was
222 received and the response sent.
225 Header add MyHeader "This request served in %D microseconds. %t"
227 results in a header being added to the response that looks like this:
229 MyHeader: This request served in D=5438 microseconds. t=991424704447256
233 *) Fix reset_filter(). We need to be careful how we remove filters.
234 If we set r->output_filters to NULL, we also have to reset the
235 connection's filters. [John Sterling]
237 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
239 *) Add a check to ap_die() to make sure the filter stack is sane and
240 contains the correct basic filters when an error occurs. This fixes
241 a problem where headers are not being sent on error. [John Sterling]
243 *) New Header directive 'echo' option. "Header echo regex" will
244 cause any headers received on the request that match regex to be
245 echoed to (included in) the response headers.
248 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
249 This prevented the inclusion of apr_compat.h. PR #7773
250 [Oleg Broytmann <phd@phd.pp.ru>]
252 *) Moved util_uri to the apr-util library. This required a bunch of
253 apr_name changes for the uri utility functions. [Justin Erenkrantz]
255 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
256 insert_filter phase so that other filters are not bypassed by default.
259 *) Reimplement mod_headers as an output filter. mod_headers can now
260 add custom headers to inbound requests using the RequestHeader directive
261 and to responses using the same old Header directive. [Graham Leggett]
263 Changes with Apache 2.0.18
265 *) Fix command-line processing so that if a bad argument is specified
266 Apache will exit. [Jeff Trawick]
268 *) Change the make targets and rules to be consistent in all of the
269 Apache-owned source trees. [Roy Fielding]
271 *) Fix processing of the TRACE method. Previously we passed bogus
272 parms to form_header_field() and it overlaid some vhost structures,
273 resulting in a segfault in check_hostalias().
274 [Greg Ames, Jeff Trawick]
276 *) Win32: Add support for reliable piped logs. If the logging process
277 goes down, Apache will automatically restart it. This function has
278 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
281 *) Do not start piped log processes during the config file
282 preflight. This change also circumvents a problem on
283 Windows where the rotatelog processes created during preflight
284 was not getting cleaned up properly.
287 *) add "Request Phase Participation" info to mod_info
290 *) Make first phase changes to the scoreboard data structures in
291 preparation for the rewriting of the scoreboard per my posted
292 design notes. [Paul J. Reder]
294 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
295 and apr-util, allow it to be overridden by the configure command-line
296 (default="--silent") and introduce LT_LDFLAGS to replace what we were
297 formerly abusing as LTFLAGS. [Roy Fielding]
299 *) Clean up the reporting of incorrect closing container tags.
300 [Barrie Slaymaker <barries@slaysys.com>]
302 *) Simplify the configure process by moving all libtool stuff to APR
303 and moving hints.m4 inline. [Roy Fielding]
305 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
306 of functions used by mod_proxy for export in the DLL
307 [Ian Holsman <IanH@cnet.com>]
309 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
310 request body from its stdin but no reqest body is being written to
311 the cgi. [Jeff Trawick]
313 *) mod_log_config: %c connection status incorrectly logged
314 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
317 *) Get mod_cern_meta working under Windows
320 *) Create Files, and thus MMAPs, out of the request pool, not the
321 connection pool. This solves a small resource leak that had us
322 not closing files until a connection was closed. In order to do
323 this, at the end of the core_output_filter, we loop through the
324 brigade and convert any data we have into a single HEAP bucket
325 that we know will survive clearing the request_rec.
326 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
329 *) Completely revamp configure so that it preserves the standard make
330 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
331 the configure additions to EXTRA_* variables. Also, allow the user
332 to specify NOTEST_* values for all of the above, which eliminates the
333 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
334 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
335 avoid pointless duplications. Fix the order in which flags are given
336 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
337 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
338 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
339 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
341 *) Get mod_tls to compile/work better on Windows. PR #7612
342 [Bernhard Schrenk <b.schrenk@improx.com>]
344 *) Fix shutdown/restart hangs in the threaded MPM.
345 [Jeff Trawick, Greg Ames, Ryan Bloom]
347 *) Removed the keptalive boolean from conn_rec because it is now only
348 used by a single routine and can be replaced by a local variable.
349 [Greg Stein, Ryan Bloom, Roy Fielding]
351 *) Patch prefork to put enough of the signal processing back in so that
352 signals are all handled properly now. The previous patch fixed the
353 deadlock race condition, but broke the user directed signal handling.
354 This fixes it to work the way it did before my previous prefork patch
355 (primarily, SIGTERM is now working).
357 *) Change how input filters decide how much data is returned to the
358 higher filter. We used to use a field in the conn_rec, with this
359 change, we use an argument to ap_get_brigade to determine how much
360 data is retrieved. [Ryan Bloom]
362 *) Fix seg fault at start-up introduced by Ryan's change to enable
363 modules to specify their own logging tags. mod_log_config
364 registers an optional function, ap_register_log_handler().
365 ap_register_log_handler() was being called by http_core before
366 the directive hash table was created. This patch creates the
367 directive hash table before ap_register_log_handler() is
368 registered as an optional function.
369 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
371 *) Add ap_set_int_slot() function
372 [John K. Sterling <sterling@covalent.net>]
374 *) Under certain circumstances, Apache did not supply the
375 right response headers when requiring authentication.
376 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
377 (This is a port of the change that went into Apache 1.3.19.)
379 *) Allow modules to specify their own logging tags. This basically
380 allows a module to tell mod_log_config that when %x is encountered
381 a specific function should be called. Currently, x can be any single
382 character. It may be more useful to make this a string at some point.
385 Changes with Apache 2.0.17
387 *) If a higher-level filter handles the the byterange aspects of a
388 request, then the byterange filter should not try to redo the
389 work. The most common case of this happening, is a byterange
390 request going through the proxy, and the origin server handles
391 the byterange request. The proxy should ignore it.
392 [Graham Leggett <minfrin@sharp.fm>]
394 *) Changed the threaded mpm to have child_main join to each of the
395 worker threads to make sure the kids are all gone before child_main
396 exits after a signal (cleanup from perform_idle_server_maintenance).
397 This is an extension of Ryans recent commit to make the child_main
400 *) Add more options to the ap_mpm_query function. This also allows MPMs to
401 report if their threads are dynamic or static. Finally, this also
402 implements a new API, ap_show_mpm, which returns the MPM that was
403 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
405 *) Do not install the binaries from the support directory twice.
406 [jun-ichiro hagino <itojun@iijlab.net>]
408 *) The ap_f* functions should flush data to the filter that is passed
409 in, not the the filter after the one passed in.
410 [Ryan Morgan <rmorgan@covalent.net>]
412 *) Make ab work again by changing its native types to apr types and formats.
413 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
415 *) Move the byterange filter and all of the supporting functions back
416 to the HTTP module. The byterange filter turned out to be very
417 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
419 *) Make clean, distclean, and extraclean consistently according to the
420 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
422 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
423 This may have been causing problems stopping processes in the threaded
426 *) Fix content-length in mod_negotiation to a long int representation.
429 *) Remove BindAddress from the default config file.
430 [giles@nemeton.com.au]
432 *) Allow module authors to add a module to their Apache build using
433 --with-module, without re-running buildconf. The syntax is:
434 --with-module=module_type:/path/to/module.c
435 The configure script will copy the module.c file to
436 modules/module_type, and it will be added to the relevant Makefiles.
437 currently, this only works for static modules. [Ryan Bloom]
439 *) Changes required to make prefork clean up idle children properly.
440 There was a window during which a starting worker deadlocks when
441 an idle cleanup arrives before it completes init. Apache then keeps
442 trying to cleanup the same deadlocked worker forever (until higher
443 pids come along, but it still will never reduce below the deadlocked
444 pid). Thus the number of children would not reduce to the correct
445 idle level. [Paul J. Reder]
447 Changes with Apache 2.0.16
449 *) Change the default installation directory to /usr/local/apache2,
450 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
452 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
455 *) Get MaxRequestsPerChild working with the Windows MPM.
458 *) Make generic hooks to work, with mod_generic_hook_import/export
459 experimental modules. [Ben Laurie, Will Rowe]
461 *) Fix segfaults for configuration file syntax errors such as
462 "<Directory>" followed by "</Directory" and
463 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
465 *) Cleanup the --enable-layout option of configure. This makes
466 us use a consistent location for the config.layout file, and it
467 makes configure more portable.
468 [jun-ichiro hagino <itojun@iijlab.net>]
470 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
471 csv/gnuplot format, rudimentary ssl support and various other tweaks
472 to make results more true to what is measured. The upshot of this it
473 turns out that 'ab' has often underreported the true performance of
474 apache. Often by a order of magnitude :-) See talk/paper of Sander
475 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
476 [Dirk-Willem van Gulik]
478 *) Clean up mod_cgid's temporary request pool. Besides fixing a
479 storage leak this ensures that some unnecessary pipes are closed.
482 *) Performance: Add quick_handler hook. This hook is called at the
483 very beginning of the request processing before location_walk,
484 translate_name, etc. This hook is useful for URI keyed content
485 caches like Mike Abbott's Quick Shortcut Cache.
488 *) top_module global variable renamed to ap_top_module [Perl]
490 *) Move ap_set_last_modified to the core. This is a potentially
491 controversial change, because this is kind of HTTP specific. However
492 many protocols should be able to take advantage of this kind of
493 information. I expect that headers will need one more layer of
494 indirection for multi-protocol work, but this is a small step in
495 the right direction. [Ryan Bloom]
497 *) Enable mod_status by default. This matches what Apache 1.3 does.
500 *) Add a ScriptSock directive to the default config file. This is
501 only enabled when mod_cgid is used.
502 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
504 Changes with Apache 2.0.15
506 *) Untangled the buildconf script and eliminated the need for build's
507 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
508 libtool muck that is now under srclib/apr/build. [Roy Fielding]
510 *) Win32: Don't accept more connections than we have worker threads
514 *) Fix bug in the Unix threaded.c MPM that allowed child processes
515 to fork() new child processes.
518 *) Fix a major security problem with double-reverse lookup checking.
519 Previously, a client connecting over IPv4 would not be matched
520 properly when the server had an IPv6 listening socket. PR #7407
521 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
523 *) Change the way the beos MPM handles polling to allow it to stop and
524 restart. Problem was the sockets being polled were being reset by
525 the select call, so once it had accepted a connection it was no
526 longer listening on the UDP socket we use for shutdown instructions.
527 APR needs to be altered, patch on it's way. [David Reid]
529 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
530 on error exit from ap_getline(). Some other code got upset because
531 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
533 *) Handle ap_discard_request_body() being called more than once.
534 [Greg Ames, Jeff Trawick]
536 *) Get rid of an inadvertent close of file descriptor 2 in
537 mod_mime_magic. [Greg Ames, Jeff Trawick]
539 *) Add a hook, create_request. This hook allows modules to modify
540 a request while it is being created. This hook is called for all
541 request_rec's, main request, sub request, and internal redirect.
542 When this hook is called, the the r->main, r->prev, r->next
543 pointers have been set, so modules can determine what kind of
544 request this is. [Ryan Bloom]
546 *) Cleanup the build process a bit more. The Apache configure
547 script no longer creates its own helper scripts, it just
549 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
551 *) Stop the forced downgrade of the connection to HTTP/1.0 for
552 proxy requests. [Graham Leggett]
554 *) Avoid using sscanf to determine the HTTP protocol number in
555 the common case because sscanf is a performance hog. From
556 Mike Abbot's Accelerating Apache patch number 6.
557 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
559 *) Fix a security exposure in mod_access. Previously when IPv6
560 listening sockets were used, allow/deny-from-IPv4-address rules
561 were not evaluated properly (PR #7407). Also, add the ability to
562 specify IPv6 address strings with optional prefix length on Allow
563 and Deny. [Jeff Trawick]
565 *) Enhance rotatelogs so that a UTC offset can be specified, and
566 the logfile name can be formatted using strftime(3). (Brought
567 forward from 1.3.) [Ken Coar]
569 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
570 DuplicateHandle on an IOCompletionPort (a practice which
571 MS "discourages"). The new model does not rely on associating
572 the completion port with the listening sockets, thus the
573 completion port can be completely managed within the child
574 process. A dedicated thread accepts connections off the network,
575 then calls PostQueuedCompletionStatus() to wake up worker
576 threads blocked on the completion port.
579 *) Bring forward the --suexec-umask option which allows the
580 builder to preset the umask for suexec processes. [Ken Coar]
582 *) Add a -V flag to suexec, which causes it to display the
583 compile-time settings with which it was built. (Only
584 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
586 *) Mod_include should always unset the content-length if the file is
587 going to be passed through send_parsed_content. There is no to
588 determine if the content will change before actually scanning the
589 entire content. It is far safer to just remove the C-L as long
590 as we are scanning it. [Ryan Bloom]
592 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
593 request and not Proxy-Authenticate.
594 [Graham Leggett <minfrin@sharp.fm>]
596 Changes with Apache 2.0.14
598 *) Fix content-length computation. We ONLY compute a content-length if
599 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
600 or we already have all the data. [Ryan Bloom]
602 *) Report unbounded containers in the config file. Previously, a typo
603 in the </container> directive could result in the rest of the config
604 file being silently ignored, with undesired defaults used.
607 *) Make the old_write filter use the ap_f* functions for the buffering.
610 *) Move more code from the http module into the core server. This
611 is core code, basically the default handler, the default input
612 and output filters, and all of the core configuration directives.
613 All of this code is required in order for the server to work, with or
614 without HTTP. The server is closer to working without the HTTP
615 module, although there is still more to do. [Ryan Bloom]
617 *) Fix a number of SGI compile warnings throughout the server. Fix some
618 bad parameters to apr_bucket_read(). Fix a bad statement in
619 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
620 consistently; we were mixing apr_time_t and time_t in invalid ways
621 before. In load_file(), call apr_dso_error() instead of
622 apr_strerror() so that we get a more specific string on some platforms.
623 PR #6980 [Jeff Trawick]
625 *) Allow modules to query the MPM about it's execution profile. This
626 query API can and should be extended in the future, but for now,
627 max_daemons, and threading or forking is a very good start.
628 [Jon Travis <jtravis@covalent.net>]
630 *) Modify mod_include to send blocks of data no larger than 9k.
631 Without this, mod_include will wait until the whole file is parsed,
632 or the first tag is found to send any data to the client.
633 [Paul J. Reder <rederpj@raleigh.ibm.com>]
635 *) Fix mod_info, so that <Directory> and <Location> directives are
636 not displayed twice when displaying the current configuration.
637 [Ryan Morgan <rmorgan@covalent.net>]
639 *) Add config directives to override DEFAULT_ERROR_MSG and
640 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
641 [Dan Rench <drench@xnet.com>]
643 *) Get mod_info building and loading on Win32. [William Rowe]
645 *) Begin to move protocol independant functions out of mod_http. The goal
646 is to have only functions that are HTTP specific in the http directory.
649 Changes with Apache 2.0.13
651 *) Don't assume that there will always be multiple calls to the byterange
652 filter. It is possible that we will need to do byteranges with only
653 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
655 *) Move the error_bucket definition from the http module to the
656 core server. Every protocol will need this ability, not just
659 Changes with Apache 2.0.12
661 *) Modify mod_file_cache to save pre-formatted strings for
662 content-length and last-modified headers for performance.
663 [Mike Abbot <mja@trudge.engr.sgi.com>]
665 *) Namespace protect IOBUFSIZ since it is exposed in the API.
666 [Jon Travis <jtravis@covalent.net>]
668 *) Use "Basic" authentication instead of "basic" in ab, as the spec
669 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
671 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
672 without ever filling it out. This fixes PR 7271.
673 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
674 Cliff Woolley <cliffwoolley@yahoo.com>]
676 *) Add a couple of GCC attribute tags to printf style functions.
677 [Jon Travis <jtravis@covalent.net>]
679 *) Add the correct language tag for interoperation with the Taiwanese
680 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
682 *) Migrate the perchild MPM to use the new apr signal child, and
683 APR thread functions. [Ryan Bloom]
685 *) Close one copy of the CGI's stdout before creating the new process.
686 The CGI will still have stdout, because we have already dup'ed it.
687 This keeps Apache from waiting forever to send the results of a CGI
688 process that has forked a long-lived child process.
689 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
691 *) Remove the rest of the pthreads functions from the threaded MPM.
692 This requires the APR support for a signal thread that was just
695 *) Make mod_dir use a fixup for sending a redirect to the browser.
696 Before this, we were using a handler, which doesn't make much
697 sense, because the handler wasn't generating any data, it would
698 either return a redirect error code, or DECLINED. This fits the
699 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
701 *) Make the threaded MPM use APR threads instead of pthreads.
704 *) Get mod_tls to the point where it actually appears to work in all cases.
707 *) implement --enable-modules and --enable-mods-shared for "all" and
710 *) Move the threaded MPM to use APR locks instead of pthread locks.
713 *) Rename mpmt_pthread to threaded. This is more in line with the
714 fact that mpmt_pthread shouldn't be using pthreads directly, and
715 it is a smaller name that doesn't tie into anything.
718 *) Rename the module structures so that the exported symbol matches
719 the file name, and it is easier to automate the installation
720 process (generating LoadModule directives from the module filenames).
723 *) Remove the coalesce filter. With the ap_f* functions, this filter
724 is no longer needed. [Ryan Bloom]
726 Changes with Apache 2.0.11
728 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
729 added feature of allowing a uid/gid per child process. If no
730 uid/gid is specified, then Perchild behaves exactly like dexter.
733 *) Get perchild building again. [Ryan Bloom]
735 *) Don't disable threads just because we are using the prefork MPM.
736 If somebody wants to compile without threads, they must now add
737 --disable-threads to the configure command line. [Ryan Bloom]
739 *) Begin to move the calls to update_child_status into common code, so
740 that each individual MPM does not need to update the scoreboard itself.
743 *) Allow mod_tls to compile under Unix boxes where openssl has been
744 installed to the system include files.
745 [Gomez Henri <new-httpd@slib.fr>]
747 *) Cleanup the mod_tls configure process. This should remove any need
748 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
749 configure doesn't check that yet. [Ryan Bloom]
751 *) Add a very early prototype of SSL support (in mod_tls.c). It is
752 vital that you read modules/tls/README before attempting to build
755 *) Fix a potential seg fault on all platforms. David Reid fixed this
756 on BEOS, but the problem could happen anywhere, so we don't want
757 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
759 *) Add new LogFormat directive, %D, to log time it takes to serve a
760 request in microseconds. [Bill Stoddard]
762 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
763 SetOutputFilter. This corresponds nicely with the other Set
764 directives, which operate on containers while the Add* directives
765 tend to work directly on extensions. [Ryan Bloom]
767 *) Cleanup the header handling a bit. This uses the apr_brigade_*
768 functions for the buffering so that we don't need to compute
769 the length of the headers before we actually create the header
772 *) Allow filters to buffer data using the ap_f* functions. These have
773 become macros that resolve directly to apr_brigade_*.
776 *) Get the Unix MPM's to do a graceful restart again. If we are going
777 to register a cleanup with ap_cleanup_scoreboard, then we have to
778 kill the cleanup with the same function, and that function can't be
781 *) Install all required header files. Without these, it was not
782 possible to compile some modules outside of the server.
785 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
786 forward from 1.3 to 2.0, we missed a single line, which broke regex
787 aliases. [Ryan Bloom]
789 *) We have a poor abstraction in the protocol. This is a temporary
790 hack to fix the bug, but it will need to be fixed for real. If
791 we find an error while sending out a custom error response, we back
792 up to the first non-OK request and send the data. Then, when we send
793 the EOS from finalize_request_protocol, we go to the last request,
794 to ensure that we aren't sending an EOS to a request that has already
795 received one. Because the data is sent on a different request than
796 the EOS, the error text never gets sent down the filter stack. This
797 fixes the problem by finding the last request, and sending the data
798 with that request. [Ryan Bloom]
800 *) Make the server status page show the correct restart time, and
801 thus the proper uptime. [Ryan Bloom]
803 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
804 should reduce the amount of duplicate code that is required to
805 create CGI processes.
806 [Paul J. Reder <rederpj@raleigh.ibm.com>]
808 *) ap_new_connection() closes the socket and returns NULL if a socket
809 call fails. Usually this is due to a connection which has been
810 reset. [Jeff Trawick]
812 *) Move the Apache version information out of httpd.h and into release.h.
813 This is in preparation for the first tag with the new tag and release
816 *) Begin restructuring scoreboard code to enable adding back in
817 the ability to use IPC other than shared memory.
818 Get mod_status working on Windows again. [Bill Stoddard]
820 *) Make mod_status work with 2.0. This will work for prefork,
821 mpmt_pthread, and dexter. [Ryan Bloom]
823 *) Correct a typo in httpd.conf.
824 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
826 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
828 *) Get the correct IP address if ServerName isn't set and we can't
829 find a fully-qualified domain name at startup.
830 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
832 *) Make mod_cgid work with SuExec. [Ryan Bloom]
834 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
835 'extra' stat's for user/group since they should never occur, and now
836 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
837 volumes. [William Rowe]
839 *) Adopt apr features to simplify mod_includes. This changes the
840 behavior of the USER_NAME variable, unknown uid's are now reported
841 as USER_NAME="<unknown>" rather than the old user#000 result.
842 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
844 *) Adopt apr features for simplifing mod_userdir, and accept the new
845 Win32/OS2 exceptions without hiccuping. [William Rowe]
847 *) Replace configure --with-optim option by using and saving the
848 environment variable OPTIM instead. This is needed because configure
849 options do not support multiple flags separated by spaces.
852 *) Fix some byterange handling. If we get a byte range that looks like
853 "-999999" where that is past the end of the file, we should return
854 a PARTIAL CONTENT status code, and return the whole file as one big
855 byterange. This matches the 1.3 handling now. [Ryan Bloom]
857 *) Make the error bucket a real meta-data bucket. This means that the
858 bucket length is 0, and a read returns NULL data. If one of these
859 buckets is passed down after the headers are sent, this data will
860 just be ignored. [Greg Stein]
862 *) The prefork MPM wasn't killing child processes correctly if a restart
863 signal was received while the process was serving a request. The child
864 process would become the equivalent of a second parent process. If
865 we break out of the accept loop, then we need to do die after cleaning
866 up after ourselves. [Ryan Bloom]
868 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
869 restarts. [Ryan Bloom]
871 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
872 the most optimal APR_FINFO_wanted bits. This spares Win32 from
873 performing very expensive owner, group and permission lookups
874 and allows the server to function until these apr_finfo_t fields
875 are implemented under Win32. [William Rowe]
877 *) Support for typedsafe optional functions - that is functions exported by
878 optional modules, which, therefore, may or may not be present, depending
879 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
880 for sample code. [Ben Laurie]
882 *) filters can now report an HTTP error to the server. This is done
883 by sending a brigade where the first bucket is an error_bucket.
884 This bucket is a simple bucket that stores an HTTP error and
885 a string. Currently the string is not used, but it may be needed
886 to output an error log. The http_header_filter will find this
887 bucket, and output the error text, and then return
888 AP_FILTER_ERROR, which informs the server that the error web page
889 has already been sent. [Ryan Bloom]
891 *) If we get an error, then we should remove all filters except for
892 those critical to serving a web page. This fixes a bug, where
893 error pages were going through the byterange filter, even though
894 that made no sense. [Ryan Bloom]
896 *) Relax the syntax checking of Host: headers in order to support
897 iDNS. PR#6635 [Tony Finch]
899 *) Cleanup the byterange filter to use the apr_brigade_partition
900 and apr_bucket_copy functions. This removes a lot of very messy
901 code, and hopefully makes this filter more stable.
904 *) Remove AddModule and ClearModuleList directives. Both of these
905 directives were used to ensure that modules could be enabled
906 in the correct order. That requirement is now gone, because
907 we use hooks to ensure that modules are in the correct order.
910 *) When SuExec is specified, we need to add it to the list of
911 targets to be built. If we don't, then any changes to the
912 configuration won't affect SuExec, unless 'make suexec' is
913 specifically run. [Ryan Bloom]
915 *) Cleaned out open_file from mod_file_cache, as apr now accepts
916 the APR_XTHREAD argument to open a file for consumption by
917 parallel threads on win32. [William Rowe]
919 *) Correct a bug in determining when we follow symlinks. The code
920 expected a stat -1 result, not an apr_status_t positive error.
921 Also check if the APR_FINFO_USER fields are valid before we
922 follow the link. [William Rowe]
924 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
925 mpm_common.c. These functions are only valid on some platforms,
926 so they should not be in the main-line code. [Ryan Bloom]
928 *) Remove ap_chdir_file(). This function is not thread-safe,
929 and nobody is currently using it. [Ryan Bloom]
931 *) Do not try to run make depend if there are no .c files in the
932 current directory, doing so makes `make depend` fail.
935 *) Update highperformance.conf to work with either prefork or
936 pthreads mpms. [Greg Ames]
938 *) Stop checking to see if this is a pipelined request if we know
939 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
940 This keeps us from making an extra read call when serving a 1.0
941 request. [Ryan Bloom and Greg Stein]
943 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
944 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
945 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
947 *) Fix the RFC number mentioned when complaining about a missing
948 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
950 *) Fix an endless loop in ab which occurred when ab was posting
951 and the server dropped the connection unexpectedly.
954 *) Fix a segfault while handling request bodies in ap_http_filter().
955 This problem has been seen with mod_dav usage as well as with
956 requests where the body was just being discarded. [Jeff Trawick]
958 *) Some adjustment on the handling and automatic setting (via
959 hints.m4) of various compilation flags (eg: CFLAGS). Also,
960 add the capability to specify flags (NOTEST_CFLAGS and
961 NOTEST_LDFLAGS) which are used to compile Apache, but
962 not used during the configuration process. Useful for
963 flags like "-Werror". [Jim Jagielski]
965 *) Stop using environment variables to force debug mode or
966 no detach. We now use the -D command line argument to
967 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
968 [Greg Stein, Ryan Bloom]
970 *) Change handlers to use hooks. [Ben Laurie]
972 *) Stop returning copies of filenames from both apr_file_t and
973 apr_dir_t. We pstrdup the filenames that we store in the
974 actual structures, so we don't need to pstrdup the strings again.
977 *) mod_cgi: Fix some problems where the wrong error value was being
978 traced. [Jeff Trawick]
980 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
983 *) Add generic hooks. [Ben Laurie]
985 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
987 *) Fix a segfault caused by mod_ext_filter when the external filter
988 program does not exist. [Jeff Trawick]
990 *) Fix an output truncation error when on an HTTP >= 1.0 request an
991 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
992 was served through mod_charset_lite (or anything else that would
993 create a transient bucket in this size range). ap_bucket_make_heap()
994 silently failed (fixed), transient_setaside() discovered it, but
995 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
997 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
998 is that some browsers send extra lines at the end of POST requests, and
999 we don't want to delay sending data back to the user just because the
1000 browser isn't well behaved. [Ryan Bloom]
1002 *) Get SuEXEC working again. We can't send absolute paths to suExec
1003 because it refuses to execute those programs. SuEXEC also wasn't
1004 always recognizing configuration changes made using the autoconf
1007 *) Allow the buildconf process to find the config.m4 files in the correct
1008 order. Basically, we can now name config.m4 files as config\d\d.m4,
1009 and we will sort them correctly when inserting them into the build
1010 process. [Ryan Bloom]
1012 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1013 This also allows mod_cgid to use ap_os_create_priviledged_process,
1014 thus allowing for SuExec execution from mod_cgid. Currently, we do
1015 not support everything that standard SuExec supports, but at least
1016 it works minimally now. [Ryan Bloom]
1018 *) Allow SuExec to be configured from the ./configure command line.
1021 *) Update some of the docs in README and INSTALL to reflect some of
1022 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1024 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1025 need to call sendfile again. This gets us serving large files
1026 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1028 *) Get the support programs building cleanly again.
1029 [Cliff Woolley <cliffwoolley@yahoo.com>]
1031 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1032 current directory logic now backs up over bin/ to determine the
1033 server root from the Apache.exe path.
1035 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1036 loadable modules, dynamic libs are all named libfoo.dll, and the
1037 makefile.win populates the include, lib and libexec directories.
1039 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1040 Apache gets IPv6 listening sockets by default. Additionally, the
1041 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1042 numeric address strings (e.g., "Listen [fe80::1]:8080").
1045 *) Modify the install directory layout. Modules are now installed in
1046 modules/. Shared libraries should be installed in libraries/, but
1047 we don't have any of those on Unix yet. All install directories
1048 are modifyable at configure time. [Ryan Bloom]
1050 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1052 *) Get the functions in server/linked into the server, regardless of
1053 which modules linked into the server. This uses the same hack
1054 for Apache that we use for APR and apr-util to ensure all of the
1055 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1056 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1057 the scripts a bit easier.
1060 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1061 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1063 *) Get all of the auth modules to the point that they will install and
1064 be loadable into the server. Our new build/install mechanism expects
1065 that all modules will have a common name format. The auth modules
1066 didn't use that format, so we didn't install them properly.
1069 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1070 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1072 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1074 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1075 after the end of the response. [Ryan Bloom]
1077 *) Get byterange requests working with responses that do not have a
1078 content-length. Because of the way byterange requests work, we have to
1079 have all of the data before we can actually do the byterange, so we
1080 can compute the content-length in the byterange filter.
1083 *) Get exe CGI's working again on Windows.
1086 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1087 they keep track of whether or not their post config hook has been
1088 called before. Instead of a static variable (which is replaced when
1089 the DSO is loaded a second time), use userdata in the process pool.
1092 Changes with Apache 2.0a9
1094 *) Win32 now requires perl to complete the final install step for users
1095 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1096 and installs the conf, htdocs and htdocs/manual directories.
1099 *) Make mod_include use a hash table to associate directive tags with
1100 functions. This allows modules to implement their own SSI tags easily.
1101 The idea is simple enough, a module can insert it's own tag and function
1102 combination into a hash table provided by mod_include. While mod_include
1103 parses an SSI file, when it encounters a tag in the file, it does a
1104 hash lookup to find the function that implements that tag, and passes
1105 all of the relevant data to the function. That function is then
1106 responsible for processing the tag and handing the remaining data back
1107 to mod_include for further processing.
1108 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1110 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1111 fewer parameters: the local and remote socket addresses were removed
1112 from the parameter list because all required information is available
1113 via the APR socket. [Jeff Trawick]
1115 *) Distribution directory structure reorganized to reflect a
1116 normal source distribution with external install targets.
1119 *) The MPMs that need multiple segments of shared memory now create
1120 two apr_shmem_t variables, one for each shared memory allocation.
1121 the problem is that we can't determine how much memory will be required
1122 for shared memory allocations once we try to allocate more than one
1123 variable. The MM code automatically aligns the shared memory allocations,
1124 so we end up needing to pad the amount of shared memory we want based
1125 on how many variables will be allocated out of the shared memory segment.
1126 It is just easier to create a second apr_shmem_t variable, and two
1127 shmem memory blocks.
1130 *) Cleanup the export list a bit. This creates a single unified list of
1131 functions exported by APR. The export list is generated at configure
1132 time, and that list is then used to generate the exports.c file.
1133 Because of the way the export list is generated, we only export those
1134 functions that are valid on the platform we are building on.
1137 *) Enable logging the cookie with mod_log_config
1138 [Sander van Zoest <sander@covalent.net>]
1140 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1143 *) Added lib/aputil/ as a placeholder for utility functions which are not
1144 specific to the Apache HTTP Server (but do not make sense with APR).
1145 The first utility is "apu_dbm": a set of functions to work with DBM
1146 files. This first version can be compiled for SDBM or GDBM databases.
1149 *) Complete re-write of mod_include. This makes mod_include a filter that
1150 uses buckets directly. This has now served the FAQ correctly.
1151 [Paul Reder <rederpj@raleigh.ibm.com>]
1153 *) Allow modules to specify the first filter in a sub_request when
1154 making the sub_request. This keeps modules from having to change the
1155 output_filter immediately after creating the sub-request, and therefore
1156 skip the sub_req_output_filter. [Ryan Bloom]
1158 *) Update ab to accept URLs with IPv6 literal address strings (in the
1159 format described in RFC 2732), and to build Host header fields in
1160 the same format. This allows IPv6 literal address strings to be
1161 used with ab. This support has been tested against Apache 1.3 with
1162 the KAME patch, but Apache 2.0 does not yet work with this format
1163 of the Host header field. [Jeff Trawick]
1165 *) Accomodate an out-of-space condition in the piped logs and the
1166 rotatelogs.c code, and no longer churn log processes for this
1167 condition. [Victor J. Orlikowski]
1169 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1172 Changes with Apache 2.0a8
1174 *) Add a directive to mod_mime so that filters can be associated with
1178 *) Get multi-views working again. We were setting the path_info
1179 field incorrectly if we couldn't find the specified file.
1182 *) Fix 304 processing. The core should never try to send the headers
1183 down the filter stack. Always, just setup the table in the request
1184 record, and let the header filter convert it to data that is ready
1188 *) More fixes for the proxy. There are still bugs in the proxy code,
1189 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1193 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1196 *) APR: Add new apr_getopt_long function to handle long options.
1197 [B. W. Fitzpatrick <fitz@red-bean.com>]
1199 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1200 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1201 hostname resolution/address string parsing and building
1202 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1203 of one of the apr_sockaddr_t structures for a socket. Change
1204 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1206 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1207 I have proxied pages with it, cleanup will commence soon.
1210 *) Make the proxy work with filters. This isn't perfect, because we
1211 aren't dealing with the headers properly. [Ryan Bloom]
1213 *) Do not send a content-length iff the C-L is 0 and this is a head
1214 request. [Ryan Bloom]
1216 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1217 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1219 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1221 *) Get the default_handler to stop trying to deal with HEAD requests.
1222 The idea is to let the content-length filter compute the C-L before
1223 we try to send the data. If we can get the C-L correctly, then we
1224 should send it in the HEAD response.
1227 *) The Header filter can now determine if a body should be sent based
1228 on r->header_only. The general idea of this is that if we delay
1229 deciding to send the body, then we might be able to compute the
1230 content-length correctly, which will help caching proxies to cache
1231 our data better. Any handler that doesn't want to try to compute
1232 the content-length can just send an EOS bucket without data and
1233 everything will just work.
1236 *) Add the referer to the error log if one is available.
1237 [Markus Gyger <mgyger@itr.ch>]
1239 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1240 change, the root of the configuration tree has been exposed to modules
1242 [Ryan Morgan <rmorgan@covalent.net>]
1244 *) Get the core_output_filter to use the bucket interface directly.
1245 This keeps us from calling the content-length filter multiple times
1246 for a simple static request.
1249 *) We are sending the content-type correctly now.
1250 [Ryan Bloom and Will Rowe]
1252 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1253 a bogus bytes-sent value when the only thing being sent was trailers
1254 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1256 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1257 hints file to determine which platforms define
1258 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1261 *) APR: add apr_get_home_directory() [Jeff Trawick]
1263 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1265 *) Not all platforms have INADDR_NONE defined by default. Apache
1266 used to make this check and define INADDR_NONE if appropriate,
1267 but APR needs the check too, and I suspect other applications will
1268 as well. APR now defines APR_INADDR_NONE, which is always a valid
1269 value on all platforms.
1270 [Branko Èibej <brane@xbc.nu>]
1272 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1273 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1275 *) Relax the syntax checking of Host: headers in order to support
1276 iDNS. PR#6635 [Tony Finch]
1278 *) When reading from file buckets we convert to an MMAP if it makes
1279 sense. This also simplifies the default handler because the
1280 default handler no longer needs to try to create MMAPs.
1283 *) BUFF has been removed from the main server. The BUFF code will remain
1284 in the code until it has been purged from the proxy module as well.
1287 *) Byteranges have been completely re-written to be a filter. This
1288 has been tested, and I believe it is working correctly, but it could
1289 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1290 the output from 1.3, the only difference being that 1.3 includes
1291 a content-length in the response, and this does not.
1294 *) APR read/write functions and bucket read functions now operate
1295 on unsigned integers, instead of signed ones. It doesn't make
1296 any sense to use signed ints, because we return the error codes,
1297 so if we have an error we should report 0 bytes read or written.
1300 *) Always compute the content length, whether it is sent or not.
1301 The reason for this, is that it allows us to correctly report
1302 the bytes_sent when logging the request. This also simplifies
1303 content-length filter a bit, and fixes the actual byte-reporing
1304 code in mod_log_config.c
1307 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1308 it says, because it was only used by EOS and FLUSH buckets. Since
1309 neither of those are required at the end of a brigade, this was
1310 really signifying FLUSH_THE_DATA, but that can be determined better
1311 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1312 buckets now return a length of 0, which is actually the amount of data
1313 read, so they make more sense.
1316 *) Allow the core_output_filter to save some data past the end of a
1317 request. If we get an EOS bucket, we only send the data if it
1318 makes sense to send it. This allows us to pipeline request
1319 responses. As a part of this, we also need to allocate mmap
1320 buckets out of the connection pool, not the request pool. This
1321 allows the mmap to outlive the request.
1324 *) Make blocking and non-blocking bucket reads work correctly for
1325 sockets and pipes. These are the only bucket types that should
1326 have non-blocking reads, because the other bucket types should
1327 ALWAYS be able to return something immediately.
1330 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1331 server, but use Ctrl+Break to initiate a graceful restart
1332 instead of duplicating behavior. [John Sterling]
1334 *) Patch mod_autoindex to set the Last-Modified header based on
1335 the directory's mtime, and add the ETag header. [William Rowe]
1337 *) Merge the 1.3 patch to add support for logging query string in
1338 such a way that "%m %U%q %H" is the same as "%r".
1341 *) Port three log methods from mod_log_config 1.3 to 2.0:
1342 CLF compliant '-' byte count, method and protocol.
1345 *) Add a new LogFormat directive, %c, that will log connection
1346 status at the end of the response as follows:
1347 'X' - connection aborted before the response completed.
1348 '+' - connection may be kept-alive by the server.
1349 '-' - connection will be closed by the server.
1352 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1353 Unicode file names and paths for Win32, and tag the Content-Type
1354 from mod_autoindex to reflect that charset if the the feature
1355 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1357 *) Compute the content length (and add appropriate header field) for
1358 the response when no content length is available and we can't use
1359 chunked encoding. [Jeff Trawick]
1361 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1362 so that content input filters get dechunked data when using
1363 the default handler. Also removed REQUEST_CHUNKED_PASS.
1366 *) Add mod_ext_filter as an experimental module. This module allows
1367 the administrator to use external programs as filters. Currently,
1368 only filtering of output is supported. [Jeff Trawick]
1370 *) Most Apache functions work on EBCDIC machines again, as protocol
1371 data is now translated (again). [Jeff Trawick]
1373 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
1374 the EBCDIC support. They are noops on ASCII machines, so this
1375 type of translation doesn't have to be surrounded by #ifdef
1376 CHARSET_EBCDIC. [Jeff Trawick]
1378 *) Fix mod_include. tag commands work again, and the server will
1379 send the FAQ again. This also allows mod_include to set aside
1380 buckets that include partial buckets.
1381 [Ryan Bloom and David Reid]
1383 *) Add suexec support back. [Manoj Kasichainula]
1385 *) Lingering close now uses the socket directly instead of using
1386 BUFF. This has been tested, but since all we can tell is that it
1387 doesn't fail, this needs to be really hacked on.
1390 *) Allow filters to modify headers and have those headers be sent to
1391 the client. The idea is that we have an http_header filter that
1392 actually sends the headers to the network. This removes the need
1393 for the BUFF to send headers.
1396 *) Charset translation: mod_charset_lite handles translation of
1397 request bodies. Get rid of the xlate version of ap_md5_digest()
1398 since we don't compute digests of filtered (e.g., translated)
1399 response bodies this way anymore. (Note that we don't do it at
1400 all at the present; somebody needs to write a filter to do so.)
1403 *) Input filters and ap_get_brigade() now have a input mode parameter
1404 (blocking, non-blocking, peek) instead of a length parameter.
1407 *) Update the mime.types file to the registered media types as
1408 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
1411 *) Namespace protect some macros declared in ap_config.h
1414 *) Support HTTP header line folding with input filtering.
1417 *) Mod_include works again. This should still be re-written, but at
1418 least now we can serve an SHTML page again.
1421 *) Begin to remove BUFF from the core. Currently, we keep a pointer
1422 to both the BUFF and the socket in the conn_rec. Functions that
1423 want to use the BUFF can, functions that want to use the socket,
1424 can. They point to the same place.
1427 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
1428 [Tomas "Ögren" <stric@ing.umu.se>]
1430 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
1431 associated pool goes away. (APR pipes on OS/2 were already had this
1432 logic.) This resolvs a fatal file descriptor leak with CGIs.
1435 *) The final line of the config file was not being read if there was
1436 no \n at the end of it. This was caused by apr_fgets returning
1437 APR_EOF even though we had read valid data. This is solved by
1438 making cfg_getline check the buff that was returned from apr_fgets.
1439 If apr_fgets return APR_EOF, but there was data in the buf, then we
1440 return the buf, otherwise we return NULL.
1443 *) Piped logs work again in the 2.0 series.
1446 *) Restore functionality broken by the mod_rewrite security fix:
1447 rewrite map lookup keys and default values are now expanded
1448 so that the lookup can depend on the requested URI etc.
1449 PR #6671 [Tony Finch]
1451 *) Tighten up the syntax checking of Host: headers to fix a
1452 security bug in some mass virtual hosting configurations
1453 that can allow a remote attacker to retrieve some files
1454 on the system that should be inaccessible. [Tony Finch]
1456 *) Add a pool bucket type. This bucket is used for data allocated out
1457 of a pool. If the pool is cleaned before the bucket is destroyed, then
1458 the data is converted to a heap bucket, allowing it to survive the
1462 *) Add a flush bucket. This allows modules to signal that the filters
1463 should all flush whatever data they currently have. There is no way
1464 to actually force them to do this, so if a filter ignores this bucket,
1465 that's life, but at least we can try with this.
1468 *) Add an output filter for sub-requests. This filter just strips the
1469 EOS bucket so that we don't confuse the main request's core output
1470 filter by sending multiple EOS buckets. This change also makes sub
1471 requests start to send EOS buckets when they are finished.
1474 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
1475 makes ap_bucket_destroy a return void, which is okay because it
1476 used to always return APR_SUCCESS, and nobody ever checked its
1477 return value anyway.
1478 [Cliff Woolley <cliffwoolley@yahoo.com>]
1480 *) Remove the index into the bucket-type table from the buckets
1481 structure. This has now been replaced with a pointer to the
1482 bucket_type. Also add some macros to test the bucket-type.
1485 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
1486 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
1487 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
1488 All _VAR_ flavors changes to _DATA to be absolutely clear.
1491 *) Add support for /, //, //servername and //server/sharename
1492 parsing of <Directory> blocks under Win32 and OS2.
1493 [Tim Costello, William Rowe, Brian Harvard]
1495 *) Remove the function pointers from the ap_bucket type. They have been
1496 replaced with a global table. Modules are allowed to register bucket
1497 types and use then use those buckets.
1500 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
1501 once we finish writing the request body to the cgi child process;
1502 otherwise, the client doesn't hit EOF on stdin. Small request bodies
1503 worked without this change (for reasons I don't understand), but large
1504 ones didn't. [Jeff Trawick]
1506 *) Remove file bucket specific information from the ap_bucket type.
1507 This has been moved to a file_bucket specific type that hangs off
1508 the data pointer in the ap_bucket type.
1511 *) Input filtering now has a third argument. This is the amount of data
1512 to read from lower filters. This argument can be -1, 0, or a positive
1513 number. -1 means give me all the data you have, I'll deal with it and
1514 let you know if I need more. 0 means give me one line and one line
1515 only. A positive number means I want no more than this much data.
1517 Currently, only 0 and a positive number are implemented. This allows
1518 us to remove the remaining field from the conn_rec structure, which
1522 *) Big cleanup of the input filtering. The goal is that http_filter
1523 understands two conditions, headers and body. It knows where it is
1524 based on c->remaining. If c->remaining is 0, then we are in headers,
1525 and http_filter returns a line at a time. If it is not 0, then we are
1526 in body, and http_filter returns raw data, but only up to c->remaining
1527 bytes. It can return less, but never more.
1528 [Greg Ames, Ryan Bloom, Jeff Trawick]
1530 *) mod_cgi: Write all of the request body to the child, not just what
1531 the kernel would accept on the first write. [Jeff Trawick]
1533 *) Back out the change that moved the brigade from the core_output_filters
1534 ctx to the conn_rec. Since all requests over a given connection
1535 go through the same core_output_filter, the ctx pointer has the
1539 *) Fix another bug in the send_the_file() read/write loop. A partial
1540 send by apr_send would cause unsent data in the read buffer to
1541 get clobbered. Complete making send_the_file handle partial
1542 writes to the network.
1545 *) Fix a couple of type fixes to allow compilation on AIX again
1546 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
1548 *) Fix bug in send_the_file() which causes offset to be ignored
1549 if there are no headers to send.
1552 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
1553 filter. Useful for supporting Windows 9* with a binary
1554 compiled on Windows NT.
1557 Changes with Apache 2.0a7
1559 *) Reimplement core_output_filter to buffer/save bucket brigades
1560 across multiple calls to the core_filter. The brigade will be
1561 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
1562 thresholds are hit or the EOS bucket is received.
1565 *) Create experimental filter (buffer_filter) that coalesces bytes
1566 into one large buffer before invoking the next filter in the
1567 chain. This filter is particularly useful with the current
1568 implementation of mod_autoindex when it inserted above the
1569 chunk_filter. mod_autoindex generates a lot of brigades that
1570 containing buckets holding just a few bytes each. The
1571 buffer_filter coalesces these buckets into a single large bucket.
1574 *) Add apr_sendfile() support into the core_output_filter.
1577 *) Add apr_sendv() support into the core_output_filter.
1580 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
1581 [Mike Abbott <mja@sgi.com>]
1583 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
1584 make much sense, because Apache uses buckets instead of BUFFs now.
1587 *) send_the_file now falls back to a read/write loop on platforms that
1588 do not have sendfile.
1589 [Ryan Bloom and Brian Havard]
1591 *) Install apachectl correctly, and substitute the proper values so
1592 that it works again. [Ryan Bloom]
1594 *) Better(??) handle platforms that lack sendfile().
1597 *) APR now has UUID generation/formatting/parsing support.
1600 *) Begin the http_filter. This is an input filter that understands
1601 the absolute basic amount required to parse an HTTP Request. The
1602 goal is to be able to split headers from request body before passing
1603 the data back to the other filters.
1606 *) Bring forward from 1.3.13 the config directory implementation
1609 *) install apxs if it is created
1612 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
1613 conversions. [William Rowe]
1615 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
1616 ap_add_output_filter(). [Jeff Trawick]
1618 *) Multiple build and configuration fixes
1621 -add datadir and localstatedir substitutions
1623 -fix logfilename misspelling
1624 -fix evaluation of installation dir variables and
1625 -replace $foobar by $(foobar) to be usefull in the makefile
1629 -add rules for cross-compiling in rules.mk. Okay, rule to check for
1630 $CC_FOR_BUILD is still missing
1631 -use CHECK_TOOL instead of CHECK_PROG for ranlib
1632 -add missing "AR=@AR@" to severaly Makefile.in's
1633 -cache result for "struct rlimit"
1634 -compile all helper programs with native and cross compiler
1635 and use the native version to generate header file
1636 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1638 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
1640 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1642 *) Fix a bug where a client which only sends \n to delimit header
1643 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
1644 message. Start working on ebcdic co-existance with input
1646 [William Rowe, Greg Ames]
1648 *) If mod_so is enabled in the server always create libexec, even
1649 if there are no modules installed in this directory. This is a
1650 requirement for APXS to work correctly.
1653 *) Connection oriented output filters are now stored in the
1654 conn_rec instead of the request_rec. This allows us to add the
1655 output filter in the pre-connection phase instead of the
1656 post_read_request phase, which keeps us from trying to write an
1657 error page before we have a filter to write to the network.
1658 [Ryan Bloom, Jeff Trawick, and Greg Ames]
1660 *) Cleaning up an mmap bucket no longer deletes the mmap. An
1661 mmap can be used across multiple buckets (default_handler with
1662 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
1663 the mmap itself can't be associated with the bucket.
1666 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1669 *) Radical surgery to improve mod_isapi support under Win32.
1670 Includes a number of newer ServerSupportFunction calls, support
1671 for ReadClient (in order to retrieve POSTs greater than 48KB),
1672 and general bug fixes to more reliably load ISAPI .dll's and
1673 prevent leaking handle resources. Note: There are still
1674 discrepancies between IIS's and Apache's ServerVariables, and
1675 async calls are still not supported. Additional warnings are
1676 logged to facilitate debugging of unsupported ISAPI calls.
1679 *) Add input filtering to Apache. The basic idea for the input
1680 filters is the same as the ideas for output filters. The biggest
1681 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1682 should be called, and the order of execution for the filter itself is
1683 different. When writing an output filter, a brigade is passed in,
1684 and filters operate directly on that brigade, when done, they call
1685 ap_pass_brigade. Input filters are the exact opposite. Because input
1686 is not a push operation, filters first call ap_get_brigade. When this
1687 function returns, the input filter will be left with a valid brigade.
1688 The input filter should then operate on the brigade, and return.
1691 *) Fix building on BSD/OS using its native make. The build system
1692 falls back to the BSD .include directive on that host platform.
1695 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1696 SHA1 and plaintext password encodings. Make feature tests a
1697 bit more flexible. [William Rowe]
1699 *) Charset translation: mod_charset_lite handles output content
1700 translation in a filter. mod_charset_lite no longer ignores
1701 subrequests. A bunch of cruft related to BUFF's support for
1702 translating request and response bodies was removed.
1705 *) Move the addition of the CORE filter to the post_read_request
1706 hook in http_core.c. This removes the need to add the filter in
1707 multiple places and allows for an SSL module to be added much
1708 simpler. [Ryan Bloom]
1710 *) Fix a security problem that affects certain configurations of
1711 mod_rewrite. If the result of a RewriteRule is a filename that
1712 contains expansion specifiers, especially regexp backreferences
1713 $0..$9 and %0..%9, then it may be possible for an attacker to
1714 access any file on the web server. [Tony Finch]
1716 *) Fix a bug where errors that are detected during early request parsing
1717 don't produce visible HTTP error messages at the browser, because
1718 the core_filter wasn't present. [Greg Ames]
1720 *) Provide apr_socklen_t as a portability aid.
1721 [Victor J. Orlikowski]
1723 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1724 as well as a comment arg to the add, adduser and update cmds.
1725 update allows the user to clear or preserve pw/groups/comment.
1726 Fixed a bug in dbmmanage that prevented the check option from
1727 parsing a password followed by :group... text. Corrected the
1728 seed calcualation for Win32 systems, and added -lsdbm support.
1731 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1734 *) Avoid a segfault when parsing .htaccess files. An
1735 uninitialized tree pointer was passed to ap_build_config().
1738 *) Change the way that inet_addr & inet_network are checked for
1739 in APR's configure process to allow BeOS BONE to correctly
1740 find them. With this change BeOS BONE now builds from source
1741 with no problems. [David Reid]
1743 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1744 the end of the parameters to execve() was stored in the wrong
1745 location, overlaying the storage beyond the newargs[] array and
1746 also passing uninitialized storage to execve(), which would
1747 sometimes fail with EFAULT. [Jeff Trawick]
1749 *) Fix a bug parsing configuration file containers. With a sequence
1750 like this in the config file
1752 <IfModule mod_kilroy.c>
1755 <IfModule mod_lovejoy.c>
1760 the second container would be terminated at the blank line due to
1761 sediment in the buffer from reading the prior </IfModule> and an
1762 error message would be generated for the real </IfModule> for the
1763 second container. Also due to this problem, any two characters
1764 could be used for "</" in the close of a container.
1767 *) ap_add_filter prototype changed to remove the ctx pointer. The
1768 pointer still remains in the filter structure, but it can not be
1769 a part of the ap_add_filter prototype. The reason is that when
1770 the core uses AddFilter to add a filter to the stack it doesn't
1771 know how to allocate the ctx pointer, or even how much memory should
1772 be allocated. The filters will have to be responsible for allocating
1773 the ctx memory when they need it.
1776 *) Add an AddFilter directive. This directive takes a list of filters
1777 that should be activated for the requested resource.
1780 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1781 some other platforms). [Jeff Trawick]
1783 *) Modify mod_include to be a filter. Currently, it has only been tested
1784 on actual files, but it should work for CGI scripts too.
1787 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1788 writes. apr_flush() for Unix: handle interrupted writes.
1791 *) NameVirtualHost can now take "*" as an argument instead of
1792 an IP address. This allows you to create a purely name-based
1793 virtual hosting server that does not have any IP addresses in
1794 the configuration file and which ignores the local address
1795 of any connections. PR #5595, PR #4455 [Tony Finch]
1797 *) Fix some compile warnings in mod_mmap_static.c
1798 [Mike Abbott <mja@sgi.com>]
1800 *) Fix chunking problem with CGI scripts. The general problem was that
1801 the CGI modules were adding an EOS bucket and then the core added an
1802 EOS bucket. The chunking filter finalizes the chunked response when it
1803 encounters an EOS bucket. Because two EOS buckets were sent, we
1804 finalized the response twice. The fix is to make sure we only send one
1805 EOS, by utilizing a flag in the request_rec.
1808 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1809 and Win32. Previously, the first read from an apr_file_t set up via
1810 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1812 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1813 bucket, instead of using BUFF's and ap_r*.
1816 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1817 [Mike Abbott <mja@sgi.com>]
1819 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1820 code to use APR file's directly instead of going through BUFFs.
1823 *) Fix compile break on some platforms for mod_mime_magic.c
1824 [John K. Sterling <sterling@covalent.net>]
1826 *) Fix merging of AddDefaultCharset directive.
1827 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1829 *) Minor revamp of the rlimit sections of code. We now test
1830 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1831 is now "available" even if the platform doesn't support
1832 the rlimit family (it's just a noop though). [Jim Jagielski]
1834 *) Migrate the pre-selection of which MPM to use for specific
1835 platforms to hints.m4, which contains (or should contain)
1836 all platform specific "hints". [Jim Jagielski]
1838 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1841 *) Add tables with non-string/binary values to APR.
1844 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1847 *) Update PCRE to version 3.2. [Ryan Bloom]
1849 *) Change the way buckets' destroy functions are called so that
1850 they can be more directly used when changing the type of a
1851 bucket in place. [Tony Finch]
1853 *) Add generic support for reference-counting the resources used by
1854 buckets, and alter the HEAP and MMAP buckets to use it. Change
1855 the way buckets are initialised to support changing the type of
1856 buckets in place, and use it when setting aside TRANSIENT buckets.
1857 Change the implementation of TRANSIENT buckets so that it can be
1858 mostly shared with IMMORTAL buckets, which are now implemented.
1861 Changes with Apache 2.0a6
1863 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1865 *) Add a chunking filter to Apache. This brings us one step closer
1866 to removing BUFF. [Ryan Bloom]
1868 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1869 added to the stack is the last filter to be called. [Ryan Bloom]
1871 *) Apache 2.0 has been completely documented using Scandoc. The
1872 docs can be generated by running 'make docs'. [Ryan Bloom]
1874 *) Add filtered I/O to Apache. This is based on bucket brigades,
1875 Currently the buckets still use BUFF under the covers, but that
1876 should change quickly. The only currently written filter is the
1877 core filter which just calls ap_bwrite. [The Apache Group]
1879 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
1880 built with thread support. [Jeff Trawick]
1882 *) Abort configuration if --with-layout was specified and there's
1883 no layout definition file. [Ken Coar]
1885 *) Add support for '--with-port=n' option to configure. [Ken Coar]
1887 *) Add support for extension methods for the Allow response header
1888 field, and an API routine for accessing r->allowed and the
1889 list of extension methods in a unified manner. [Ken Coar]
1891 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
1892 [Rob Simonson <simo@us.ibm.com>]
1894 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
1895 APACHE_XLATE builds. [Jeff Trawick]
1897 *) A configuration file parsing problem was fixed. When the
1898 configuration file started with an IfModule/IfDefine container,
1899 only the last statement in the container would be retained.
1902 Changes with Apache 2.0a5
1904 *) Perchild is serving pages after passing them to different child
1905 processes. There are still a lot of bugs, but this does work. I
1906 have made requests against the same installation of Apache, and had
1907 different servers use different user IDs to serve the responses.
1908 This change moves to using socketpair instead of an AF_UNIX socket.
1911 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
1912 It can't seem to pass between child processes yet, but I think we
1913 are closer now than before. This moves us back to using Unix
1914 Domain Sockets. [Ryan Bloom]
1916 *) libapr functions and types renamed with apr_ prefix.
1917 #include "apr_compat.h" for 1.3.x backwards compat
1920 *) Fix problems with APR sockaddr handling on Win32. It didn't always
1921 return the right information on the local socket address.
1922 [Gregory Nicholls <gnicholls@level8.com>]
1924 *) ap_recv() on Win32: Set bytes-read to 0 on error.
1925 [Gregory Nicholls <gnicholls@level8.com>]
1927 *) Add an option to not detach from the controlling terminal without
1928 going into single process mode. This allows for much easier
1929 debugging of the process startup code. [Ryan Bloom]
1931 *) ab: don't use perror() to report the failure of an APR function.
1934 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
1935 scoreboard on graceful restarts.
1938 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
1939 An invalid ap_proc_t was passed to ap_create_process().
1942 *) Allow modules to register filters. Those filters are still
1943 never called, but this is a step in the right direction.
1944 [Ryan Bloom and Greg Stein]
1946 *) Register the mod_cgid daemon process for cleanup so that it is
1947 killed at termination if it does not die when the parent gets
1948 SIGTERM. This change is to fix occasional problems where the
1949 process stays around. Bugs in similar logic in mod_rewrite and
1950 mod_include were also fixed. [Jeff Trawick]
1952 *) Fix a bug in the time handling. Basically, we were imploding a time
1953 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
1954 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
1955 uses those two fields to adjust the time value. Because of the HTTP
1956 spec, both of those values can be zero'ed out safely. This fixes
1957 the bug correctly. [Ryan Bloom]
1959 *) Fix a couple of place in the Windows code where the wrong error
1960 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
1962 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
1964 *) Added the APR_EOL_STR macro for platform dependent differences in
1965 logfiles and other raw text (such as all APR files). Fixes logfiles
1966 not terminated with cr/lf sequences in Win32. [William Rowe]
1968 *) Move all strings functions in APR to src/lib/apr/strings and create
1969 apr_strings.h for the prototypes. [Ryan Bloom]
1971 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
1972 to repeat the syscall until we stop getting EINTR. I noticed a
1973 related problem at termination (SIGTERM) on FreeBSD when using
1974 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
1975 implementation work properly with child init. Previously, ap_lock()
1976 was essentially a no-op because all children were using different
1977 locks and thus nobody ever blocked. [Jeff Trawick]
1979 *) The htdocs/ tree has been moved out of the CVS source tree into
1980 a separate area for easier development. This has NO EFFECT on
1981 end-users or Apache installations. [Ken Coar]
1983 *) Integrate the mod_dav module for WebDAV protocol handling. This
1984 adds the dav and dav_fs modules, the SDBM library, and additional
1985 XML handling utilities. [Greg Stein]
1987 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
1990 *) Update the lib/expat-lite/ library (bring forward changes from
1991 the Apache 1.3 repository). [Greg Stein]
1993 *) If sizeof(long long) == sizeof(long), then prefer long in APR
1994 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
1996 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
1997 machines where sendfile is detected, but nobody has written ap_sendfile.
1998 [Dave Hill <ddhill@zk3.dec.com>]
2000 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2002 *) ab would start up more connections than needed, then quit when the
2003 desired number were finished. Also fixed a logic error involving
2004 ab keepalives. [Victor J. Orlikowski]
2006 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2007 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2008 timeouts (i.e, if a timeout was specified, the pipe reverted to
2009 a full blocking pipe). Now the behaviour is more in line with
2010 Unix non-blocking pipes.
2013 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2014 cache open file handles along with accept socket reuse enables
2015 Apache 2.0 to serve non-keepalive requests for static files at
2016 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2017 and Apache 2.0 will serve almost 1200 rps on my system).
2020 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2021 supports two config directives, mmapfile (same behavious as
2022 mod_mmap_static) and cachefile. Use the cachefile directive
2023 to cache open file handles. This directive only works on systems
2024 that have implemented the ap_sendfile API. cachefile works today
2025 on Windows NT, but has not been tested on any flavors of Unix.
2028 *) Cleanup the configuration. With the last few changes the
2029 configuration process automatically:
2030 inherits information about how to build from APR. Allowing
2031 APR to inform Apache that it should or should not use -ldl
2033 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2034 based on the threading model
2036 Apache calls APR's configure process before finishing it's
2037 configuration processing, allowing for more information flow
2042 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2043 with non-zero argument makes the socket non-blocking. BeOS and
2044 OS/2 already worked this way. [Jeff Trawick]
2046 *) ap_close() now calls ap_flush() for buffered files, so write
2047 operations work a whole lot better on buffered files.
2050 *) Fix error messages issued from MPMs which explain where to change
2051 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2054 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2055 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2056 now the way that the blocking state of a pipe is manipulated.
2057 ap_block_pipe() is gone. [Jeff Trawick]
2059 *) Correct the problem where the only local host name that the IP stack
2060 can discover are 'undotted' private names. If no fully qualified
2061 domain name can be identified, the default ServerName will be set to
2062 the machine's IP address string. A warning is always provided if the
2063 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2065 *) Repair problems with config file processing which caused segfault
2066 at init when virtual hosts were defined and which caused ServerName to
2067 be ignored when there was no valid DNS setup. [Jeff Trawick]
2069 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2071 *) Add ap_sendfile implementation for AIX
2072 [Victor J. Orlikowski]
2074 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2075 apr_network_io.h, and apr_thread_proc.h.
2076 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2078 *) Bring the allocation and pool debugging code back into a working
2079 state. This will need to be tested as so far it's only been used on
2082 *) Change configuration command setup to be properly typesafe when in
2083 maintainer mode. Note that this requires a compiler that can initialise
2084 unions. [Ben Laurie]
2086 *) Turn on buffering for config file reads. Part of this was to
2087 repair buffered I/O support in Unix and implement buffered
2088 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2090 *) Win32: Fix problem where UTC offset was not being set correctly
2091 in the access log. Problem reported on news group by Jerry Baker.
2094 *) Fix segfault when reporting this type of syntax error:
2095 "</container> without matching <container> section", where
2096 container is VirtualHost or Directory or whatever.
2099 *) Prevent the source code for CGIs from being revealed when using
2100 mod_vhost_alias and the CGI directory is under the document root
2101 and a user makes a request like http://www.example.com//cgi-bin/cgi
2102 as reported in <news:960999105.344321@ernani.logica.co.uk>
2105 *) Add support for the new Beos NetwOrking Environment (BONE)
2108 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2109 final input char is incomplete; ap_bwrite_xlate() now handles
2110 incomplete final input chars. [Jeff Trawick]
2112 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2113 that a bhalfduplex call occurs before logging or else DNS and
2114 such can delay the last packet of the response. [Dean Gaudet]
2116 *) Some syscall reduction in APR on unix -- don't seek when setting
2117 up an mmap; and don't fcntl() more than once per socket.
2120 *) When mod_cgid is started as root, the cgi daemon now switches
2121 to the configured User/Group (like other httpd processes)
2122 instead of continuing as root. [Jeff Trawick]
2124 *) The prefork MPM now uses an APR lock for the accept() mutex.
2125 It has not been getting a lock at all recently. httpd -V now
2126 displays APR's selection of the lock mechanism instead of the
2127 symbols previously respected by prefork. [Jeff Trawick]
2129 *) Change the mmap() feature test to check only for existence.
2130 The previous check required features not used by Apache.
2133 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2134 sometimes mangled. The len parm to accept() was not
2135 initialized, leading sometimes to an endless loop of failed
2136 accept() calls on OS/390 and anywhere else that failed the call
2137 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2138 instead of declaring it ourselves to fix a compilation problem
2139 on Solaris. [Jeff Trawick]
2141 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2143 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2145 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2147 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2148 initialization if ALLOC_DEBUG is defined; no known symptom
2149 otherwise. [Jeff Trawick]
2151 *) Fix typo in configure script when checking for mod_so. bash
2152 doesn't seem to have a problem but /bin/sh on Solaris does.
2153 Symptom: "./configure: test: unknown operator =="
2156 *) Rebind the Win32 NT and 9x services control into the MPM.
2157 All console, WinNT SCM and Win9x pseudo-service control code is
2158 now wrapped within the WinNT MPM.
2161 *) Make a copy of getenv("PATH") before storing for later use. Some
2162 getenv() implementations use the same storage for successive calls.
2163 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2165 *) Server Tokens work in 2.0 again. This also propogates the change
2166 to allow just the product name in the server string using
2170 Changes with Apache 2.0a4
2172 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2173 won't need to call it. [Greg Ames, Jeff Trawick]
2175 *) Move pre_config hook call to between configuration read and config
2176 tree walk. This allows all modules to implement pre_config hooks
2177 and know that they will be called at an appropriate time.
2180 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2183 *) Add pre-config hooks back to all modules.
2186 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2187 ContentDigest enabled and we can't/don't mmap the file.
2190 *) We now report the correct line number for syntax errors in config
2191 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2193 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2194 related bugs, and changed shmem/locking to use apr API. Shared-mem
2195 is currently disabled, however, because of problems with graceful
2196 restarts. [Ronald Tschalär]
2198 *) Fix corruption of IFS variable in --with-module= handling.
2199 Depending on the user's shell or customization thereof, there
2200 would be errors generating ap_config_auto.h later in the configure
2201 procedure. [Jeff Trawick]
2203 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2204 isn't used (as in 1.3), except that on Unix it is now logged via
2205 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2206 to the error log. [Greg Ames, Jeff Trawick]
2208 *) Add '-D' argument processing for run time configuration defines.
2211 *) Organize http_main.c as independent code, such that no code or
2212 global data is exported from it. WIN32 will dynamically link it
2213 to the server core, so this will prevent mutual dependency.
2216 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2217 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2220 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2221 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2223 *) Add mod_charset_lite for configuring character set translation.
2226 *) Add '-n' option to htpasswd to make it print its user:pw record
2227 on stdout rather than having to frob a text file. [Ken Coar]
2229 *) Fix saferead. Basically, we flush the output buffer if a read on the
2233 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2234 a conversion is single-byte only. [Jeff Trawick]
2236 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2237 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2240 *) Fix some minor errors where pid was being manipulated as an int
2241 instead of the portable pid_t. [Roy Fielding]
2243 *) Fix some error log prints that were printing the pointer to a
2244 structure rather than the pid within the structure.
2245 [Jeff Trawick, Roy Fielding]
2247 *) ab: Fix a command-line processing bug; track bad headers in
2248 err_response; support reading headers up to 2K.
2249 [Ask Bjoern Hansen <ask@valueclick.com>]
2251 *) Fix ap_resolve_env() so that it handles new function added in a prior
2252 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2253 config file.") as well as the constructs used by mod_rewrite.
2254 [Paul Reder <rederpj@raleigh.ibm.com>]
2256 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2258 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2259 APR to perform translation, instead of accessing the hard-coded tables
2260 in 1.3's ebcdic.c. [Jeff Trawick]
2262 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2265 *) Add the ability to hook into the config file reading phase. Basically
2266 if a directive is specified EXEC_ON_READ, then when that directive is
2267 read from the config file, the assocaited function is executed. This
2268 should only be used for those directives that must muck with HOW the
2269 server INTERPRETS the config. This should not be used for directives
2270 that re-order or replace items in the config tree. Those changes should
2271 be made in the pre-config step.
2274 *) Add mod_example to the build system.
2277 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2278 byte character sets. [Jeff Trawick]
2280 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2281 Kraemer and Oliver Reh originally according to the change log).
2284 *) Fix a couple of problems in RFC1413 support (controlled by the
2285 IdentityCheck directive). Apache did not build the request string
2286 properly and more importantly Apache would loop forever if the
2287 would-be ident server dropped the connection before sending a
2288 properly terminated response. [Jeff Trawick]
2290 *) apxs works in 2.0.
2293 *) Reliable piped logs work in 2.0.
2296 *) Introduce a hash table implementation into APR to be used for
2297 replacing tables and other random data structures in Apache.
2300 *) Add some more error reporting to htpasswd in the case of problems
2301 generating or accessing the temporary file. Also, pass in a
2302 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2303 is defined). [Ken Coar]
2305 *) Configure creates config.nice now containing your configure
2306 options. Syntax: ./config.nice [--more-options]
2309 *) Fix various return code problems in APR on Win32. For most of
2310 these, APR was returning APR_EEXIST instead of GetLastError()/
2311 WSAGetLastError(). [Jeff Trawick]
2313 *) Make piped logs work again in version 2.0
2316 *) Add VPATH support to UNIX build system of Apache and APR.
2319 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2323 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2324 Patch submitted to author.
2327 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2328 /sbin in PATH on FreeBSD (all submitted to rse previously)
2331 *) Fix building Pthread-based MPMs on OpenBSD
2332 [Sascha Schumann] PR#26
2334 *) Fix ap_readdir() problem on systems where d_name[] field in
2335 struct dirent is declared with only one byte. (This problem only
2336 affected multithreaded builds.) This caused a segfault during
2337 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
2338 least). [Jeff Trawick]
2340 *) Fix some make-portability problems on at least Tru64, Irix
2342 [Sascha Schumann] PR#18, PR#39
2344 *) Add ap_sigwait() to support old-style sigwait() on systems
2345 like OS/390 and UnixWare.
2348 *) Add POSIX-thread flags for more platforms.
2351 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2352 (on Unix, at least) to handle resolver errors. Fix a bug in
2353 the definition of APR_ENOMEM so that ap_strerror() can spit
2354 out the correct error message for it.
2357 Changes with Apache 2.0a3
2359 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2362 *) API: *HOOK* macros now have an AP_ prefix
2365 *) Win32: Eliminate redundant calls to initialize winsock.
2366 [Tim Costello <timcostello@ozemail.com.au>]
2368 *) Fix bugs initializing ungetchar for pipes.
2369 [Chia-liang Kao <clkao@CirX.ORG>]
2371 *) The ab program in the src/support directory is now portable using
2375 *) Support directory is being compiled when the server is built
2378 *) The configure option --with-program-name has been added to allow
2379 developers to rename the executable at configure time. This also
2380 changes the name of the config files to match the executable's name.
2383 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
2384 containing version numbers. [Martin Pool]
2386 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
2387 Unix; access_log and error_log now created with these perms; non-
2388 Unix is unaffected [Jeff Trawick]
2390 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
2391 Replaced more magic numbers with MD5_DIGESTSIZE.
2392 [William Rowe, Roy Fielding]
2394 *) Win32: Get mod_auth_digest compiling and added to the Windows
2395 build environment. Not tested and I'd be suprised if it
2396 actually works. [Bill Stoddard]
2398 *) Revamp the Win32 make environment. Makefiles have been removed and
2399 Apache.dsw created to bring together all the pieces. Create new file
2400 os/win32/BaseAddr.ref to define module base addresses (to prevent
2401 dll relocation at start-up).
2402 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
2404 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
2405 of the \015, \012, and \015\012 constants with macros.
2406 [Greg Ames <gregames@us.ibm.com>]
2408 *) Add ap_xlate_open() et al for translation of text between different
2409 character sets. The initial implementation requires iconv().
2412 *) More FAQs and answers from comp.infosystems.www.servers.unix.
2413 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2415 *) CGI output is being timed out now.
2418 *) Fix the problem with dieing quietly. dupfile now takes a pool which
2419 is used by the new apr file. There is no reason to create a new file
2420 with the same lifetime as the original file.
2423 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
2424 module base addresses. This will help shooting seg faults
2425 in the field. [William Rowe <wrowe@lnd.com>]
2427 *) Update Apache on Windows documentation. Add new document
2428 describing how to compile Apache on Windows.
2429 [William Rowe <wrowe@lnd.com>]
2431 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
2432 microseconds instead of seconds. Some storage leaks and other
2433 minor bugs in related code were fixed. [Jeff Trawick]
2435 *) Win32: First cut at getting mod_isapi working under 2.0
2436 [William Rowe <wrowe@lnd.com>]
2438 *) First stab at getting mod_auth_digest working under 2.0
2439 quick change summary:
2440 - moved the random byte generation (ap_generate_random_bytes) into APR
2441 - now uses ap_time_t
2442 - compiles and runs on linux
2444 [Brian Martin <bmartin@penguincomputing.com>]
2446 *) Win32: Move the space stripping of physical service names
2447 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
2448 unresolved symbol. Add dependency checking to the
2449 CreateService call to ensure TCPIP and AFP (winsock) is started
2451 [William Rowe <wrowe@lnd.com>]
2453 *) Win32: Add code to perform latebinding on functions that may
2454 not exist on all levels of Windows where Apache runs. This
2455 is needed to allow Apache to start-up on Win95/98. All calls
2456 to non portable functions should be protected with
2457 ap_oslevel checks to prevent runtime segfaults.
2458 [William Rowe <wrowe@lnd.com>]
2460 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
2462 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
2464 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
2465 This addresses PR 1623. Still need to address timing out runaway
2466 CGI scripts. [Bill Stoddard]
2468 *) Win32: Make ap_stat Windows 95/98 friendly
2469 [William Rowe <wrowe@lnd.com>]
2471 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
2472 always fail. Need to initialise the dwOSVersionInfoSize member of the
2473 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
2476 The patch also enhances ap_get_oslevel (and the associated enum) to
2477 handle selected service packs for NT4, and adds recognition for
2478 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
2479 we can use ReadFileScatter and WriteFileGather in readwrite.c.
2480 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
2482 *) Get mod_rewrite building and running, and mod_status building for Win NT
2483 [Allan Edwards <ake@raleigh.ibm.com>]
2485 *) Patch to port mod_auth_db to the 2.0 api and also to support
2486 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2487 2.7.7. It should work with version 1 as well but I haven't tested it.
2488 [Brian Martin <bmartin@penguincomputing.com>]
2490 *) Get APR DSO code working under Windows. Includes cross platform
2492 [Tim.Costello@BTFinancialgroup.com]
2494 *) Fix some of the Windows APR time functions.
2497 *) FAQ changes related to tidying up historical documents on the web site.
2498 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2500 *) Move Windows DSO code into APR.
2503 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
2504 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
2505 at build time. At this point, the server will not compile on Windows because
2506 of the recent DSO commits. Fixing those next.
2507 [Bill Rowe & Bill Stoddard]
2509 *) Added error checking for file I/O APR routines.
2510 [Jon Travis <jtravis@covalent.net>]
2512 *) APR: Don't use the values of resolver error codes for the
2513 corresponding APR error codes. On Unix and Win32, return the
2514 proper APR error code after a resolver error. [Jeff Trawick]
2516 Changes with Apache 2.0a2
2518 *) Renamed the executable back to httpd on all platforms other
2522 *) Allow BeOS to survive restarts, log properly and a few
2523 small things it had problems with due to the way it setup
2524 users and groups. [David Reid]
2526 *) Get mod_rewrite working with APR locks
2527 [Paul Reder <rederpj@raleigh.ibm.com>]
2529 *) Actually remove the sempahore when the lock cleanup routine
2530 is called on BeOS. [David Reid]
2532 *) Clear hook registrations between reads of the config file.
2533 When DSOs are unloaded and re-loaded the old hook pointers may
2534 no longer be valid. This fix eliminates potential segfaults.
2535 [Allan Edwards <ake@raleigh.ibm.com>]
2537 *) Fix a problem with Sigfunc not being defined or bypassed
2538 if sigaction() wasn't found. [Jim Jagielski]
2540 *) Fix the locking mechanism on BSD variants. They now use fcntl
2541 locks. This allows the server to start and serve pages.
2544 *) First cut at getting the Win32 installer to work
2545 [William Rowe <wrowe@lnd.com>]
2547 *) Get htpasswd compiling under Windows
2548 [William Rowe <wrowe@lnd.com>]
2550 *) Change the log message for a bind() failure to show the
2551 interface and port number. [Jeff Trawick]
2553 *) Import the documentation from 1.3.12 and bring parts of it
2554 up-to-date with respect to the changes that have occurred
2558 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
2559 now logged correctly on BeOS.
2562 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
2563 Makefile.win includes the same user interface as the old
2565 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
2567 *) Win32 exec now uses COMSPEC environment string for command
2568 shell path resolution.
2569 [William Rowe <wrowe@lnd.com>] PR#3715
2571 *) Win32: ap_connect() was not returning correct error condition
2573 [Allen Prescott <allen@clanprescott.com>]
2575 *) Win32: ap_open() was broken on Win9x because an NT-specific
2576 flag was passed to CreateFile. ap_puts() added an unnecessary
2578 [Jeff Trawick <trawick@us.ibm.com>]
2580 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
2581 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
2582 confusing ee/et name and made all extensions language/dialect
2583 rather than country reflecting. Changed example files to
2584 explicit reflect the ISO charset and added a few common
2585 ones to the example config [dirkx]
2587 *) Extend external module capability. To use this, you call
2588 configure with --with-module=path/to/mod1,path/to/mod2,etc.
2591 *) Backported the various "default charset" fixes from 1.3.12,
2592 including the AddDefaultCharset directive. [Jim Jagielski]
2594 *) Added the capability to do ${ENVVAR} constructs in the
2595 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
2596 it does this on a line by line basis; i.e. if the envvar
2597 expands to something with spaces you have to protect it
2598 by adding quotes around it (Unless of course you expect it
2599 to contains more than one argument. Alternatively you
2600 can compile it on a per token basis; which is what people
2601 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
2602 hampers fancier hacks.
2603 [Dirk-Willem van Gulik]
2605 *) Changed the 'ErrorDocument' syntax in that it NO longer
2606 supports the asymetric
2608 ErrorDocument 301 "Some message
2610 Note the opening " quote, without a closing quote. It now
2611 has either the following syntaxes
2613 ErrorDocument XXX /local/uri
2614 ErrorDocument XXX http://valid/url
2615 ErrorDocument XXX "Some Message"
2617 The recognition heuristic is: if it has a space it
2618 is a message. If it has no spaces and starts with a /
2619 or is a valid URL then treat it that way. Otherwise it
2620 is assumed to be a message.
2622 This breaks backward compatibility but makes live a hell
2623 of a lot easier for GUI's and config file parsers.
2624 [Dirk-Willem van Gulik]
2626 *) Changed 'CacheNegotiatedDocs' from its present/not-present
2627 syntax into a 'on' or 'off' syntax. As it currently is the
2628 only non nesting token which uses NO_ARGS and thus is an
2629 absolute pain for any config interface automation. This
2630 breaks backward compatibility. [Dirk-Willem van Gulik]
2632 *) Add ability to add external modules to the build process. This is
2633 done with --with-module=/path/to/module. Modules can only be added
2634 as static modules at this point.
2637 Changes with Apache 2.0a1
2639 *) Fix FreeBSD 3.3 core dump.
2640 Basically, ap_initialize() needs to get called before
2641 create_process(), since create_process() passes op_on structure
2642 to semop() to get a lock, but op_on isn't initialized until
2643 ap_initialize() calls setup_lock(). Here is a slight
2644 rearrangement to main() which calls ap_initialize() earlier...
2645 [Jeff Trawick <trawick@us.ibm.com>]
2647 *) Enable Apache to use sendfile/TransmitFile API
2648 [Bill Stoddard, David Reid, Paul Reder]
2650 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
2654 *) Make file I/O and network I/O writev/sendv APIs consistent.
2655 Eliminate use of ap_iovec_t and use Posix struct iovec.
2656 Use seperate variable on ap_writev to set the number of iovecs
2657 passed in and number of bytes written.
2660 *) Adapt file iol to use APR functions. Replaced ap_open_file()
2661 with ap_create_file_iol(). ap_create_file_iol() requires that
2662 the file be opened prior to the call using ap_open().
2665 *) Port mod_include and mod_cgi to 2.0
2666 [Paul Reder, Bill Stoddard]
2668 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2669 bytes_read/bytes_written is always valid (never -1). Plus
2670 some fixes to buff.c to correct problems introduced by the
2671 errno => ap_status_t changes a while back. Plus a fix to
2672 chunked encoding introduced right at the beginning of 2.0.
2675 *) Revamped UNIX build system to use autoconf and libtool.
2676 [Manoj Kasichainula, Sascha Schumann]
2678 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2680 *) More rigorous checking of Host: headers to fix security problems
2681 with mass name-based virtual hosting (whether using mod_rewrite
2682 or mod_vhost_alias).
2683 [Ben Hyde, Tony Finch]
2685 *) Add back support for UseCanonicalName in <Directory> containers.
2686 [Manoj Kasichainula]
2688 *) Added APLOG_STARTUP log type. This allows us to write an error
2689 message without any of the date and time information. As a part
2690 of this change, I also removed all of the calls to fprintf(stderr
2691 and replaced them with calls to ap_log_error using APLOG_STARTUP
2692 writing to stderr is no longer portable, because we don't direct
2693 stderr to the error log on all platforms.
2696 *) Convert error logging functions to take errno as an argument.
2697 This makes our error logs more portable, because some Windows API's
2698 don't set errno. This change allows us to still output a valid
2699 message on all of our platforms.
2702 *) mod_mime_magic runs in 2.0-dev now.
2703 [Paul Reder <rederpj@raleigh.ibm.com>]
2705 *) sendfile has been added to APR.
2706 [John Zedlewski <zedlwski@Princeton.EDU>]
2708 *) buff.c has been converted to no longer use errno.
2709 [Manoj Kasichainula]
2711 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2712 interface adaption to APR functions did it. [Martin Kraemer]
2714 *) Support DSOs properly on 32-bit HP-UX 11.0
2715 [Dilip Khandekar <dilip@cup.hp.com>]
2717 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2718 [Ralf S. Engelschall]
2720 *) Cleaned APR build environment integration and bootstrap APR
2721 automatically for developers from src/Configure.
2722 [Ralf S. Engelschall]
2724 *) Fixed building of src/support/htpasswd.c
2725 [Ralf S. Engelschall]
2727 *) When generating the Location: header, mod_speling forgot
2728 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2731 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2733 *) Change all pools to APR contexts. This is the first step to
2734 incorporating APR into Apache. [Ryan Bloom]
2736 *) Move "handler not found" warning message to below the check
2737 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2738 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2740 *) Support line-continuation feature in config.option file and
2741 allow the loading of multiple option sections at once via
2742 ``--with-option=<section1>,<section2>,...''
2743 [Ralf S. Engelschall]
2745 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2747 Changes with Apache MPM
2749 *) Use asynchronous AcceptEx() and a completion port to accept and
2750 dispatch connections to threads in Windows NT/2000.
2753 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2756 *) Implement the APACI --with-option facility
2757 (per default used the config.option file).
2758 [Ralf S. Engelschall]
2760 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2762 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2763 Replace pre_connection module call with a register_hook call and
2764 implement pre_connection as a hook. The intent is that these hooks will
2765 be extended to allow Apache to be multi-protocol, and also to allow the
2766 calling order to be specified on a per-hook/per-module basis.
2769 *) Implement mpm_* methods as "modules". Each method gets its own
2770 subdir in src/modules (eg: src/modules/prefork). Selection
2771 of method uses Rule MPM_METHOD. [Jim Jagielski]
2773 *) Port the hybrid server from the apache-apr repository as
2774 mpm_mpmt_pthread. [Manoj Kasichainula]
2776 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2777 amongst the unix MPMs.
2779 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2780 signal handling for the new world order. [Dean Gaudet]
2782 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2783 of alloc.c for now. [Dean Gaudet]
2785 *) Handle partial large writes correctly. [Ben Laurie]
2787 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2788 based on IP/port. [Ben Laurie]
2790 *) Port a bunch of modules to the new module structure.
2791 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2793 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2795 *) Basic restructuring to introduce the MPM concept; includes various
2796 changes to the module API... better described by
2797 docs/initial_blurb.txt. [Dean Gaudet]
2799 Changes with Apache pthreads
2801 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2802 buff operations (generally over a network).
2803 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2805 *) Created http_accept abstraction. Added 4 new functions (not exported):
2806 init_accept(), begin_accepting_requests(), get_request(),
2807 stop_accepting_requests() [Bill Stoddard]
2809 *) Fix to ap_rprintf call that allows mod_info to work properly.
2810 [James Morris <jmorris@intercode.com.au>]
2812 *) user and ap_auth_type fields were moved from connection_rec to
2813 request_rec. [Ryan Bloom]
2815 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2816 needed in a threaded server.
2818 *) Initial pthread implementation from from Dean's apache-nspr code.
2819 [Bill Stoddard, Ryan Bloom]
2822 Changes with Apache 1.3.9
2824 *) Remove bogus error message when a redirect doesn't set Location.
2825 Instead, use an empty string to avoid coredump if the error message
2826 was supposed to include a location. [Roy Fielding]
2828 *) Don't allow configure to include mod_auth_digest unless it is
2829 explicitly requested, even if the user asked for all modules.
2832 *) Translate module names to dll names for OS/2 so that they are no more
2833 than 8 characters long and have an extension of "dll" instead of "so".
2836 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2837 Fix test-compile check to check for randbyte instead of trand32.
2838 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2839 and tweak to make Amaya happier. [Ronald Tschalär]
2841 *) Ensure that the installed expat include files are world readable,
2842 just like the other header files. [Martin Kraemer]
2844 *) Fixed generated AddModule adjustments in APACI's `configure' script
2845 in order to allow (new) modules like mod_vhost_alias to be handled
2846 correctly (which was touched by the adjustments for mod_alias).
2847 [Ralf S. Engelschall]
2849 *) For binary builds, add -R flag to apachectl to work around the lack of
2850 an absolute path to the ./libexec directory where the libhttp.ep file
2851 is needed for SHARED_CORE architectures. [Randy Terbush]
2853 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2854 problem observed by some Win95/98 users where they get CGI script
2855 output sent to the console. [Bill Stoddard]
2857 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2858 routines are now called ap_base64* and are 'plain' (i.e., no
2859 pool access or anything clever). Inside util.c the routines acting
2860 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2861 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2862 now but deprecated. [dirkx]
2864 *) Clean up the base64 and SHA1 additions and make sure they are
2865 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2866 files. [Roy Fielding]
2868 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2869 checking. Allow compiling on VS 6.0. [Randy Terbush]
2871 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2873 *) Use TestCompile to search for the truerand library (rather than blindly
2874 assuming its existence). If it is not found, complain (but do not
2875 exit - yet). [Martin Kraemer]
2877 *) We forgot to add the new exported function names to
2878 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
2880 *) Add description of -T command-line option to usage().
2881 [Ralf S. Engelschall]
2883 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
2884 searched only AFTER libap has been searched, because libap needs
2885 some symbols from libos. [Martin Kraemer]
2887 *) Fix conflict with original mod_digest related to the symbol of the
2888 module dispatch list (which has to be unique for DSO and follow the
2889 usual conventions for the installation procedure).
2890 [Ralf S. Engelschall]
2892 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
2893 for other platforms as well. [Martin Kraemer]
2895 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
2896 types by AP_LONG and replace reference to renamed variable 'ubuf'
2897 by 'buffer'. [Martin Kraemer]
2899 Changes with Apache 1.3.8 [not released]
2901 *) Flush the output buffer immediately after sending an error or redirect
2902 response, since the result may be needed by the client to abort a
2903 long data transfer or restart a series of pipelined requests.
2904 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
2906 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
2907 [Ian Turner <iant@sequent.com>] PR#4735
2909 *) Local struct mmap in http_core.c conflicted with system structure
2910 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
2912 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
2913 [Ronald Tschalär <ronald@innovation.ch>]
2915 *) Fix a memory leak where the module counts were getting messed
2916 up across restarts. [David Harris <dharris@drh.net>]
2918 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
2919 properly in mod_access.
2920 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
2922 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
2923 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
2925 *) PORT: Support for compaq/tandem/com.
2926 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
2928 *) Added SHA1 password encryption support to easy migration from
2929 Netscape servers. See support/SHA1 for more information.
2930 Caused the separation of ap_md5.c into md5, sha1 and a general
2931 ap_checkpass.c with just a validate_passwd routine. Added a
2932 couple of flags to support/htpasswd. Some reuse of the to64()
2933 function; hence renamed to ap_to64().
2934 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
2936 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
2937 with ASCII/EBCDIC conversions in "ident" query.
2938 [David McCreedy <McCreedy@us.ibm.com>]
2940 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
2941 Change "Power Macintosh" to Power* so if uname prints "Power Book"
2942 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
2944 *) Fix SIGSEGV on some systems because the Vary fix below included
2945 a call to table_do with a variable argument list that was not
2946 NULL terminated. Replaced with better implementation. [Roy Fielding]
2948 Changes with Apache 1.3.7 [not released]
2950 *) The "Vary" response header field is now sanitised right before
2951 the header is sent back to the client. Multiple "Vary" fields
2952 are combined, and duplicate tokens (e.g., "Vary: host, host" or
2953 "Vary: host, negotiate, host, accept-language") are reduced to
2954 single instances. This is a better solution than the force-no-vary
2955 one (which is still valid for clients that can't cope with Vary
2956 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
2958 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
2960 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
2961 least on Linux and FreeBSD for now.
2964 *) Win32: More apache -k restart work. Restarts are now honored
2965 immediately and connections in the listen queue are -not- lost.
2966 This is made possible by the use of the WSADuplicateSocket()
2967 call. The listeners are opened in the parent, duplicated, then
2968 the duplicates are passed to the child. The original listen sockets
2969 are not closed by the parent across a restart, thus the listen queue
2971 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2973 *) Fix handling of case when a client has sent "Expect: 100-continue"
2974 and we are going to respond with an error, but get stuck waiting to
2975 discard the body in the pointless hope of preserving the connection.
2976 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
2978 *) Fix 'configure' to work correctly with SysV-based versions of
2979 'tr' (consistent with Configure's use as well). [Jim Jagielski]
2981 *) apxs: Add "-S var=val" option which allows for override of CFG_*
2982 built-in values. Add "-e" option which works like -i but doesn't
2983 install the DSO; useful for editing httpd.conf with apxs. Fix
2984 editing code so that multiple invocations of apxs -a will not
2985 create duplicate LoadModule/AddModule entries; apxs can now be
2986 used to re- enable/disable a module. [Wilfredo Sanchez]
2988 *) Win32: Update the server to use Winsock 2. Specifically, link with
2989 ws2_32.lib rather than wsock32.lib. This gives us access to
2990 WSADuplcateSocket() in addition to some other enhanced comm APIs.
2991 Win 95 users may need to update their TCP/IP stack to pick up
2992 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
2993 [Bill Stoddard stoddard@raleigh.ibm.com]
2995 *) Win32: Redirect CGI script stderr (script debug info) into the
2996 error.log when CGI scripts fail. This makes Apache on Win32
2997 behave more like Unix.
2998 [Bill Stoddard stoddard@raleigh.ibm.com]
3000 *) Fixed `httpd' usage display: -D was missing.

3010 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3011 [Randy Terbush <randy@covalent.net>]
3013 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3014 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3016 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3017 command potentially _is_ GCC. [Ralf S. Engelschall]
3019 *) Fix apxs build issues on AIX
3020 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3022 *) DocumentRoot Checking: Under previous versions, when Apache
3023 first started up, it used to do a stat of each DocumentRoot to
3024 see if it existed and was a directory. If not, then an error
3025 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3026 does not exist, you will get error messages in error_log. If
3027 the '-t' command line option is used (to check the configuration)
3028 the check of DocumentRoot IS performed. An additional command
3029 line option, '-T', has been added if you want to avoid the
3030 DocumentRoot check even when checking the configuration.
3033 *) Win32: The query switch "apache -S" didn't exit after showing the
3034 vhost settings. That was inconsistent with the other query functions.
3035 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3037 *) Win32: Changed behaviour of apache -k restart.
3038 Previously, the server would drain all connections in the stack's
3039 listen queue before honoring the restart. On a busy server, this
3040 could take hours. Now, a restart is honored almost immediately.
3041 All connections in Apache's queues are handled but connections in
3042 the stack's listen queue are discarded. Restart triggered by
3043 MaxRequestPerChild is unchanged.
3044 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3046 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3047 the accept loop. Good for a 5% performance boost. Cleaned up
3048 parent/child process management code.
3049 [Bill Stoddard <stoddard@raleigh.ibm.com>]

3056 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3058 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3059 use this at least for Expat. [Ralf S. Engelschall]
3061 *) Allow .module files to specify libraries with Lib:.
3064 *) Allow SetEnvIf[NoCase] to test environment variables as well
3065 as header fields and request attributes. [Ken Coar]
3067 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3068 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3070 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3071 never accepted into any standard, and it opens up certain DoS
3072 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3074 *) TestCompile updated. We can now run programs and output the
3075 results during the Configure process. [ Jim Jagielski]
3077 *) The source is now quad (long long) aware as needed. Specifically,
3078 the Configure process determines the correct size of off_t and
3079 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3080 provides for the 'q' format qualifier (if quads are not available,
3081 'q' is silently "demoted" to long). [Jim Jagielski]
3083 *) When the username or password fed to htpasswd is too long, include the
3084 size limit in the error message. Also report illegal characters
3085 (currently only ':') in the username. Add the size restrictions
3086 to the man page. [Ken Coar]
3088 *) Fixed the configure --without-support option so it doesn't result in
3089 an infinite loop. [Marc Slemko]
3091 *) Piped error logs could cause a segfault if an error occured
3092 during configuration after a restart.
3093 [Aidan Cully <aidan@panix.com>] PR#4456
3095 *) If a "Location" field was stored in r->err_headers_out rather
3096 than r->headers_out, redirect processing wouldn't find it and
3097 the server would core dump on ap_escape_html(NULL). Check both
3098 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3099 if Location isn't set. [Doug MacEachern, Ken Coar]
3101 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3102 of the Expat 1.0.2 distribution. [Greg Stein]
3104 *) Replace regexec() calls with calls to a new API stub function
3105 ap_regexec(). This solves problems with DSO modules which use the regex
3106 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3108 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3109 environment variables can be set according to the protocol version
3110 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

3127 *) Support for server-parsed and multiview-determined ReadmeName and
3128 HeaderName files in mod_autoindex. Removed the restriction on
3129 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3130 routines will deal with the access issues. (It's now possible to
3131 have {site|group|project|customer|...} wide readmes and headers.)

3142 handful of problems seen with mod_perl <Perl> configuration sections
3143 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3145 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3146 by default when building with APACI; allow for platform-specific
3147 variable defaults in configure. [Wilfredo Sanchez]
3149 *) Do setgid() before initgroups() in http_main; some platforms
3150 zap the grouplist when setgid() is called. This was fixed in
3151 suexec earlier, but the main httpd code missed the change.

3166 *) Fix minor but annoying bug with the test for Configuration.tmpl
3167 being newer than Configuration so that it is less likely to fail
3168 when using APACI and shadow sources. [Wilfredo Sanchez]
3170 *) PORT: Add initial support for Mac OS (versions 10.0 and
3171 greater). Use Mac OS X Server layout for now. Clean up dyld code
3172 in unix/os.c, and don't install the dyld error handlers, which
3173 are no longer needed in Mac OS. [Wilfredo Sanchez]
3175 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3176 locations to appropriate ones for user-built (as opposed to
3177 system) installs. [Wilfredo Sanchez]
3179 *) Modify mod_autoindex's handling of AddDescription so that the
3180 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3182 *) Add functionality to the install-bindist.sh script created by
3183 binbuild.sh to use tar when copying distribution files to the
3184 serverroot. This allows upgrading an existing installation
3185 without nesting the new distribution in the old.
3187 install-bindist.sh now detects the local perl5 path to install
3188 apxs and dbmmanage with proper path to perl interpreter.
3190 Add an install-binsupport target which copies the source files
3191 for apxs and dbmmanage to bindist to allow these scripts to
3192 be properly installed relative to the destination serverroot.

3359 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
3360 a roughly 5 fold speed up. [Brian Havard]
3362 *) proxy ftp: instead of using the hardwired string "text/plain" as
3363 a fallback type for files served by the ftp proxy, use the
3364 ap_default_type() function to determine the configured type.
3365 This allows for special configurations like
3366 <Directory proxy:ftp://some.host>
3367 DefaultType gargle/blurb
3369 Additionally, add the Content-Encoding: header to FTP proxy replies
3370 when the encoding is defined (by the AddEncoding directive).
3371 Because it was missing, it was almost impossible to browse compressed
3372 files using the FTP proxy (works now perfectly in Communicator).
3373 The ftp proxy now also returns the Date: and Server: header lines (if not
3374 much else... This code is "somewhat" broken) like normal requests do.
3377 *) Be more smart in APACI's configure script when determining the UID/GID
3378 for User/Group directives and use the determined UID/GID to initialize
3379 the permissions on the proxycachedir.

3453 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
3454 for 8-bit safeness. [Dean Gaudet]
3456 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
3457 because SPARCs have a small machine-specific maximum size for the Global

3459 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
3461 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

3481 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
3482 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
3483 possible buffer overflows. [Ralf S. Engelschall]
3485 *) Remove no longer used non-API function ap_single_module_init().
3486 [Ralf S. Engelschall]
3488 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
3491 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
3492 to make platform installations easier. [Wilfredo Sanchez]
3494 *) In configure, do not append the target name to the directory path if
3495 the path already contains "apache". [Ralf S. Engelschall]
3497 *) SIGPIPE is now ignored by the server core. The request write routines
3498 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
3499 correctly check for output errors and mark the connection as aborted.
3500 Replaced many direct (unchecked) calls to ap_b* routines with the
3501 analogous ap_r* calls. [Roy Fielding]
3503 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
3504 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
3505 Furthermore map lookups for non-existent keys are now cached as well.
3506 Additionally "txt" maps are now parsed with simple string functions
3507 instead of using ap_pregcomp(). As a side effect a bug that prevented
3508 the usage of keys containing the "," character was fixed.
3509 The changes drastically improve the performance when large rewrite maps
3511 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
3513 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
3514 other than GET, and const'd the definition of method in request_rec.
3517 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
3519 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
3520 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
3522 *) Add %V to mod_log_config, this logs the hostname according to the
3523 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
3524 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
3526 *) Add support for \n and \t to mod_log_config, can be used to produce
3527 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
3529 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
3531 *) Added informative error messages for failed munmap() and fseek() calls
3532 in http_core.c. [John Bley, Roy Fielding]
3534 *) Added some informative error messages for some failed malloc()
3535 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
3537 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
3538 is removed. This allows <Directory proxy:*> directives to work and
3539 prevents invalid requests from killing the process.
3540 [Brian Havard <brianh@kheldar.apana.org.au>]
3542 *) Reorganised FAQ document.

3545 *) src/support/: The ApacheBench benchmark program was overhauled by
3546 David N. Welton: you can now have it generate an HTML TABLE, presumably
3547 for integration into other HTML sources. David updated the ab man page
3548 as well and added some missing descriptions. Thanks!
3549 [David N. Welton <davidw@prosa.it>]
3551 *) Win32: The filename validity checker now allows filenames containing
3552 characters in the range 0x80 to 0xff (for example accented characters).
3553 [Paul Sutton] PR#3890
3555 *) Added conditional logging based upon environment variables to
3556 mod_log_config. mod_log_referer and mod_log_agent
3557 are now deprecated. [Ken Coar]
3559 *) Allow apache acting as a proxy server to relay the real
3560 reason of a failure to a client rather than the "internal
3561 server error" it does currently. The general exposure mechanism
3562 can be triggered by any module by setting the "verbose-error-to"
3563 note to "*"; this allows more than just proxy errors to be exposed.
3564 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
3566 *) Moved man pages for ab and apachectrl to section 8.

3569 *) Added -S option to install.sh so that options can be passed to
3570 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
3572 *) Tweak modules Makefile generated by Configure so that it handles
3573 the test case of no modules being selected. [chaz@reliant.com]
3575 *) Added a <LimitExcept method ...> sectioning directive that allows
3576 the user to assign authentication control to any HTTP method that
3577 is *not* given in the argument list; i.e., the logical negation
3578 of the <Limit> directive. This is particularly useful for controlling
3579 access on methods unknown to the Apache core, but perhaps known by
3580 some module or CGI script. [Roy Fielding, Tony Finch]
3582 *) Prevent apachectl from complaining if the PIDFILE exists but
3583 does not contain a process id, as might occur if the server is
3584 being rapidly restarted. [Wilfredo Sanchez]
3586 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
3588 *) Entity tag comparisons for If-Match and If-None-Match were not being
3589 performed correctly -- weak tags might cause false positives. Also,
3590 strong comparison wasn't properly enforced in all cases.

3596 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
3597 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
3599 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
3600 to util.c for parsing an HTTP header field value to extract the next
3601 list item, taking into account the possible presence of nested comments,
3602 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
3603 insignificant whitespace and lowercases non-quoted tokens.
3604 [Roy Fielding] PR#2065
3606 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
3607 code different from 500. This allows the proxy to, e.g., return
3608 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
3610 *) Fix ordering of language variants for the case where the traditional
3611 negotiation algorithm is being used with multiple language variants
3612 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
3614 *) Do not round the TCN quality calculation to 5 decimal places,
3615 unlike RFC 2296, because the calculation might need 12 decimal places
3616 to get the right result. [Roy Fielding]
3618 *) Remove unused code to disable transparent negotiation when
3619 negotiating on encoding only, as we now handle encoding too
3620 (though this is nonstandard for TCN), remove charset=ISO-8859-1
3621 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
3622 some debugging statements within mod_negotiation. [Koen Holtman]
3624 *) Fixed a rare memory corruption possibility in mod_dir if the index
3625 file is negotiable and no acceptable variant can be found.
3626 [Dean Gaudet, Roy Fielding, Martin Kraemer]
3628 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
3629 searching the Win32 registry for script interpreters.
3632 *) Win32: The compiled-in default filename for the error log is now
3633 error.log, which matches the default in the distributed httpd.conf.
3636 *) Win32: Any error messages from -i or -u command line options are now
3637 displayed on the console output rather than sent to the error log.
3638 Also the "Running Apache..." message is not output unless Apache is
3639 going to serve requests. [Paul Sutton]
3641 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
3642 and use a private significator ('$apr1$') to mark passwords as
3643 being smashed with our own algorithm. Also abstract the password
3644 checking into a new ap_validate_password() routine. [Ken Coar]
3646 *) Win32: The filename validity checker now allows "COM" but refuses
3647 access to "COM1" through "COM4". This allows filenames such
3648 as "com.name" to be served. [Paul Sutton] PR#3769.
3650 *) BS2000: Adapt to the new ufork() system call interface which will
3651 make subtasking easier on the OSD/POSIX mainframe environment.
3654 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
3655 ap_compat.h. [David White <david@persimmon.com>] PR#3725
3657 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.

3668 quoted strings. (This overflow was on the heap and we believe
3669 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]

3672 signs as it's the case for the HP/UX compiler.

3675 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
3676 and check to see if the tar we wind up with supports '-h'.
3677 [Jim Jagielski] PR#3671
3679 *) A consistent and conservative style for all shell scripts has been
3680 implemented. Basically, all shell string tests use the traditional
3681 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3682 to protect against bare null variable strings (ie: wrapping both
3683 sides with double quotes and prepending 'x'). 'x' was chosen
3684 because it's more universal and hopefully easier for old shell
3685 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3688 *) The status module now prints out both the main server generation as
3689 well as the generation of each process. Also, the vhost info is
3690 printed with '?notable'. [Jim Jagielski]
3692 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3693 and this makes its functions available to things in src/support.
3696 Changes with Apache 1.3.4
3698 *) Renamed macros status_drops_connection to ap_status_drops_connection
3699 and vestigial scan_script_header to ap_scan_script_header_err,
3700 mostly for aesthetic reasons. [Roy Fielding]
3702 *) The query switch "httpd -S" didn't exit after showing the
3703 vhost settings. That was inconsistent with the other query functions.
3706 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
3707 filename to the end of the STANDARD_MODULE_STUFF. Its
3708 presence at the beginning prevented reporting of the filename
3709 for modules compiled before 1 January 1999. [Ken Coar]
3711 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
3712 to detect and prevent access to special DOS device file names.
3713 [Paul Sutton, Ken Parzygnat]
3715 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
3716 and Makefile_win32_debug.txt (debug build) that work on Win95.
3717 Run each of the following from the src directory:
3718 nmake /f Makefile_win32.txt # compiles normal build
3719 nmake /f Makefile_win32.txt install # compiles and installs
3720 nmake /f Makefile_win32.txt clean # removes compiled junk
3721 nmake /f Makefile_win32_debug.txt # compiles debug build
3722 nmake /f Makefile_win32_debug.txt install
3723 nmake /f Makefile_win32_debug.txt clean
3726 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3727 to build binary distributions. [Lars Eilebrecht]
3729 *) IndexOptions SuppressColumnSorting only turned off making
3730 the column headers anchors; you could still change the display
3731 order by manually adding a '?N=A' or similar query string to the
3732 URL. Now SuppressColumnSorting locks in the sort order so
3733 it can't be overridden this way. [Ken Coar]
3735 *) Added IndexOrderDefault directive to supply a default sort order
3736 for FancyIndexed directory listings. [Ken Coar] PR#1699
3738 *) Change the ap_assert macro to a variant that works on all platforms.
3739 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3741 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3742 search for an underscore on dlsym() (as it's already the case
3743 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3745 *) Small fix for mod_env.html: The module was documented as to be _not_
3746 compiled into Apache per default, although it _IS_ compiled into
3747 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3749 *) Instead of fixing a bug in the generation procedure for config.status (a
3750 backslash was missing) we remove the bug together with it's complete
3751 context because the special cases of the past can now no longer occur
3752 because of the recent magic for the --with-layout default.
3753 [Ralf S. Engelschall] PR#3590
3755 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3756 making sure the src/support/ tools are _forced_ to be build last (they
3757 depend on other libraries).
3758 [Markus Theissinger <markus.theissinger@gmx.de>]
3760 *) Fix installation procedure: Now that os-inline.c is actually used (a
3761 recently fixed bug prevented this) we need to also install os-include.c
3762 in addition to os.h into the PREFIX/include/ location or building of
3763 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3765 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3766 allow us to distinguish between a garbled DSO (or even a file which isn't
3767 an Apache module DSO at all) and a DSO which doesn't match the current
3768 Apache API. [Ralf S. Engelschall] PR#3152
3770 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3771 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3772 match case insensitive (this especially avoids nasty patterns like
3773 `[tT][eE][sS][tT]'). Second two additional internal map functions
3774 `escape' and `unescape' were added which can be used to escape/unescape
3775 to/from hex-encodings in URLs parts (this is especially useful in
3776 combination with map lookups).
3777 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3779 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3780 forgotten (because it was a macro) in the symbol renaming process.
3781 [Ralf S. Engelschall]
3783 *) Fix some inconsistencies related to the scopes of directives. The only
3784 user visible change is that the directives `UseCanonicalName' and
3785 `ContentDigest' now use the (more correct) `Options' scope instead of
3786 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3788 *) Using DSO, the Server token was being mangled. Specifically, the
3789 module's token was being added first before the Apache token. This
3790 has been fixed. [Jim Jagielski]
3792 *) Major overhaul of mod_negotiation.c, part 2.
3793 - properly handle "identity" within Accept-Encoding.
3794 - allow encoded variants in RVSA negotiation and let them appear in
3795 the Alternates field using the non-standard "encoding" tag-list.
3796 - fixed both negotiation algorithms so that an explicitly accepted
3797 encoding is preferred over no encoding if "identity" is not
3798 included within Accept-Encoding.
3799 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3800 of large substring sequences.
3801 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3804 *) Major overhaul of mod_negotiation.c, part 1.
3805 - cleanups to mod_negotiation comments and code structure
3806 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3807 support for everything in the upcoming HTTP/1.1
3808 revision (draft-ietf-http-v11-spec-rev-06.txt).
3809 - language tag matching also handles tags with more than 2
3811 - empty Accept, Accept-Language, Accept-Charset headers are
3812 processed correctly; previously an empty header would make all
3813 values acceptable instead of unacceptable.
3814 - allowed for q values in Accept-Encoding
3815 - added support for transparent content negotiation (rfc2295 and
3816 rfc2296) (though we do not implement all features in these drafts,
3817 e.g. no feature negotiation). Removed old experimental version.
3818 - implemented 'structured entity tags' for better cache correctness
3819 (structured entity tags ensure that caches which can deal with Vary
3820 will (eventually) be updated if the set of variants on the server
3822 - this involved adding a vlist_validator element to request_rec
3823 - this involved adding the ap_make_etag() function to the global API
3824 - modified guessing of charsets used by Apache negotiation algorithm
3825 to guess 'no charset' if the variant is not a text/* type
3826 - added code to sort multiviews variants into a canonical order so that
3827 negotiation results are consistent across backup/restores and mirrors
3828 - removed possibility of a type map file resolving to another type map
3829 file as its best variant

3843 *) For %v log ServerName regardless of the UseCanonicalName
3844 setting (similarly for %p). [Dean Gaudet]
3846 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
3847 rather late (too late for some invocations of TestCompile).
3848 This improves the make environment available to TestCompile and
3849 the *.module scripts. [Martin Kraemer]
3851 *) The hashbang emulation code in ap_execve.c would interpret
3852 #!/hashbang/scripts correctly, but failed to fall back to a
3853 standard shell for scripts which did NOT start with #!
3854 Now SHELL_PATH is started in these cases. [Martin Kraemer]
3856 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
3859 *) Update APXS manual page: some -q option arguments were missing
3860 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3862 *) Cleanup the command line options: `-?' was documented to show
3863 the usage list but does it with an error because `?' is not a valid
3864 command. OTOH a lot of users expect `-h' to print such a usage list and
3865 instead are annoyed for ages by our huge unreadable list of directives.
3866 So we now changed the command line options this way:
3868 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3869 very similar to the popular linker option.
3871 Intent: while -l gives the small list of modules, -L now gives the
3872 large list of directives implemented by these modules. This is also
3873 consistent with -v (short version info) and -V (large version info).
3875 Intent: it's now the expected option ;-)
3876 The manual page was adjusted accordingly.
3877 [Ralf S. Engelschall] PR#2714
3879 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
3880 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
3882 *) Removed recently introduced bugs and disfigurements in APACI:
3883 o fixed argument line processing: using $args was broken: It was not
3884 initialized and using args="$args $apc_option" and even args="$args
3885 \"$apc_option\"" fails in the second processing round for any arguments
3886 containing whitespaces. The only correct way is to use the construct
3887 "$@" (but not possible here) or iterate _both_ times over the implicit
3888 argument line (no argument to for-loop) which is what we now use.
3889 o make --with-layout=Apache the default without creating
3890 redundancy (copying the --with-layout block in the argument parsing
3891 loop). We achieve this by using the "$@" construct together with the
3892 `set' command to prepend --with-layout=Apache to the command line in
3893 case --with-layout is not used.
3894 o fixed auto-suffix handling now that config.layout exists.
3895 Paths which are auto-suffixed are marked with a trailing plus sign in
3896 config.layout and every path now can be marked this way (not only the
3897 four paths for which we do it currently). Additionally the suffix is
3898 no longer a static one. Instead it's now `/<target>' where <target> is
3899 the argument of the --target option or per default `httpd'.
3900 o allow also tabs (and only spaces) where we match whitespaces
3901 o various fixes and cleanups related to used shell coding style
3902 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
3903 o trimmed output of --help to fit into 80 columns

3925 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
3926 [Tom Serkowski <tks@bsdi.com>] PR#3453
3928 *) Make generation of src/Configuration.apaci more robust: It failed to
3929 differenciate between modules when one module name was a postfix of
3930 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
3931 just XXX (think about totally non-standard names like "apache_ssl", too).
3932 [Ralf S. Engelschall] PR#3380
3934 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
3935 since 1.3b7) and make whitespace handling more robust (it failed horrible
3936 when whitespaces were present in the arguments of -D options).
3937 [Ralf S. Engelschall] PR#3240
3939 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
3940 creates an external package shadow tree in DIR before the local build
3941 shadow tree is generated under DIR. This way one can have the extracted
3942 Apache distribution tree read-only on NFS or CDROM and still build Apache
3943 from these sources. An automatically triggered VPATH-like mechanism is
3944 provided through the TOP variable, too.

3958 and the usage page was inconsistent with the functionality and manpage.

3961 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
3962 They can occur multiple times and their arguments (`xxx') are passed AS
3963 IS to the compiler/linker command. [Ralf S. Engelschall]
3965 *) Fixed possible (but harmless in practice) bug in the DBM lookup
3966 procedure of mod_rewrite: very long keys were truncated.
3967 [Ralf S. Engelschall]
3969 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
3970 identifier, currently "Apache" and "GNU" are pre-defined in the file
3971 config.layout. Custom layouts are possible by using FILE:ID as the
3972 argument where the layout ID is taken from FILE.
3974 The config.layout file consists of <Layout ID>..</Layout> sections
3975 where inside those sections "path_variable: path_value" pairs can be
3976 specified. These lines are converted to path_variable='path_value'.
3978 *) Add a DefaultLanguage directive so that files missing a language
3979 extension (e.g., .fr, .de) can be labelled as being some other
3980 default language. DefaultLanguage can appear in <Directory> and
3981 <Files> containers as well as .htaccess files. [Paul Sutton]
3984 *) Fix TARGET configuration when configuring and installing using
3985 APACI configure. TARGET now defines the basename of the configuration
3986 file, startup script, manual page, etc. log_error_core() now reports
3987 the server binary name given by argv[0]. TARGET can now also be defined
3988 with --target=TARGET parameter passed to APACI configure.

4011 notice to the error log. It is not possible to send a 401 response
4012 and a redirect at the same time. [Lars Eilebrecht]
4014 *) Fallback to native compilers for IRIX-32 platform. It seems that
4015 a gcc 2.8.1 compiled apache is logging client addresses with all
4016 bits set (255.255.255.255). This is the second such problem caused
4017 by gcc 2.8.1 compiler. The first being broken semaphore locking.
4020 *) Updated mime.types to reflect current Internet media types
4021 and include a URL to the registry.

4028 used to set the document root directory (DOC_ROOT) and the suexec
4029 logfile (LOG_EXEC), respectively. Additionally the --layout option
4030 was changed to show more information about the suEXEC setup.

4038 modules, Limit, and Script directives. That includes PATCH,
4039 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
4040 Improved mod_actions.c so that it can use any of the methods

4067 *) Disable sending of error-notes on a 500 (Internal Server Error) response
4068 since it often includes file path info. Enable sending of error-notes
4069 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
4071 *) http_config.c would respond with 501 (Method Not Implemented) if a
4072 content type handler was specified but could not be found, which
4073 should have been a 500 response. Likewise, mod_proxy.c would responsd
4074 with a 501 if the URI scheme is unrecognized instead of the correct
4075 response of 403 (Forbidden). [Roy Fielding]

4081 unavailable, an empty string was printed which was 2 bytes short.
4082 The size and description columns were therefore not aligned correctly.

4090 scoreboard file and avoid a string copy (as well as allow some
4091 further future enhancements). [Harrie Hazewinkel
4092 <harrie.hazewinkel@jrc.it>]
4094 *) Add APACI --permute-module=foo:bar option which can be used to
4095 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
4096 in the Configuration[.apaci] file. Two special and important variants are
4097 supported for the option argument: first BEGIN:foo which permutes module
4098 mod_foo with the begin of the module list, i.e. it `moves' the module to
4099 the begin of the list (gives it lowest priority). And second foo:END
4100 which permutes mod_foo with the end of the module list, i.e. it `moves'
4101 the module to the end of the list (gives it highest priority).

4177 useful for PUT responses that result in 302 or 401. [Roy Fielding]
4179 *) Remove extra trailing whitespace from the getline results as part
4180 of the protocol processing, which is extra nice because it works
4181 between continuation lines, is almost no cost in the normal case
4182 of no extra whitespace, and saves memory. [Roy Fielding]

4304 You now must define a BS2000Account name for the server User.
4305 This has fewer security implications than the old approach.
4308 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
4309 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
4310 platform to make the braindead HPUX linker happy. Notice, for the module
4311 DSOs we don't have to use this, because these are loaded manually (and

4323 *) Make PrintPath work generically instead of having one version
4324 strictly for OS/2. [Jim Jagielski, Brian Havard]
4326 *) Fix the recently introduced C header file checking: We now use the C
4327 pre-processor pass only (and no longer the complete compiler pass) to
4328 determine whether a C header file exists or not. Because only this way
4329 we're safe against inter-header dependencies (which caused horrible
4330 portability problems). The only drawback is that we now have a CPP
4331 configuration variable which has to be determined first (we do a similar
4332 approach as GNU Autoconf does here). When all fails the user still has
4333 the possibility to override it manually via APACI or src/Configuration.
4334 As a fallback for the header check itself we can directly check the
4335 existance of the file under /usr/include, too.

4384 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
4386 *) mod_expires will now act on content that is not sent from a file
4387 on disk. Previously it would never add an Expires: header to
4388 any response that did not come from a file on disk; the only
4389 case where it still doesn't (and can't) add one for that type of
4390 content is if you are using a modification date based setting.

4408 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
4410 *) The <IfModule and <IfDefine block starting directives now only
4411 allow exactly one argument. Previously, the optional negation
4412 character '!' could be separated by whitespace without a syntax
4413 error being reported, albeit defeating the IfModule functionality
4414 (enclosed directives would ALWAYS be executed). By using the
4415 stricter syntax, these hard-to-track errors can be avoided.
4418 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
4419 cause the standalone FancyIndexing directive to logically OR
4420 into any existing IndexOptions settings rather than wiping
4421 them out. [Ken Coar]
4423 *) Changes in ftp proxy: make URL parsing simpler by using the
4425 + Add display of the "current directory" in cases where it's
4426 different from the supplied path (e.g., ftp://user@host/ lives
4427 in /home/user, not in /, therefore clicking on "../" in the
4428 starting directory might send us to /home/).
4429 + When ftp login fails, (esp. when a user name was part of the
4430 URL already), we now return [401 Unauthorized ] to allow the
4431 browser to pop up an authorization dialog. This makes passwords
4432 slightly less visible (they don't appear in the regular log files)
4433 and implements a functionality that other www proxy servers
4437 *) Triggered by the recent "Via:" header changes, the proxy module would
4438 dump core for replies with invalid headers (e.g., duplicate
4439 "HTTP/1.0 200 OK" lines). These errors are now logged and the
4440 core dump is avoided. Also, broken replies are not cached.
4441 [Martin Kraemer] PR#2914
4443 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
4444 plop gmon.out profile data for each child [Doug MacEachern]
4446 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
4447 config.status script to be immune against arguments with whitespaces.
4448 [Yves Arrouye <yves@apple.com>] PR#2866
4450 *) Replace the inlined information grabbing stuff for the configuration
4451 adjustment feature (no --without-confadjust) with calls to a new helper
4452 script `buildinfo.sh' which is both more flexible and already proofed to
4453 be more robust against platform differences. This mainly fixes the
4454 recently occured ``sed: command garbled: ...'' problems.
4455 [Ralf S. Engelschall] PR#2776, PR#2848
4457 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
4458 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
4459 without complains after we recently added the POST feature.
4460 [Ralf S. Engelschall]
4462 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
4463 modules as API functions and we forgot them at the big symbol renaming.
4464 [Ralf S. Engelschall]
4466 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

4472 *) Add the ability to do POST requests to the ab benchmarking tool.
4473 [Kurt Sussman <kls@best.com>] PR#2871
4475 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
4476 5 to 10 because there are some users out there who always have 5 to 8
4477 variables in one RewriteRule and had to patch mod_rewrite.h for every
4478 release. So 15 should be now more than enough, even for them. (I never
4479 needed more than 4 in my RewriteRules ;-)
4480 [Ralf S. Engelschall]
4482 *) Make the proxy generate and understand Via: headers
4485 *) Change the proxy to use tables instead of array_headers for
4486 the header lines. [Martin Kraemer]
4488 *) Make sure the config.status file is not overridden when just
4489 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
4491 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
4492 provide a way to trace API changes that add functionality but do
4493 not create a compatibility issue for precompiled modules, etc.
4494 See include/ap_mmn.h for more details. [Randy Terbush]
4496 *) Fix suexec installation under `make install root=xxx' situation.
4497 [Ralf S. Engelschall]
4499 *) Extend the output of the -V switch to include the paths of all
4500 compiled-in configuration files, if they were overridden at
4501 compile time, for least astonishment of the user.
4504 *) When READing a request in ExtendedStatus mode, the "old"
4505 vhost, request and client information is not displayed.
4508 *) STATUS is no longer available. Full status information now
4509 run-time configurable using the ExtendedStatus directive.
4512 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
4513 cpu time attacks) in header parsing. Add ap_overlap_tables(),
4514 a function which can be used to perform bulk update operations
4515 on tables in a more efficient manner. [Dean Gaudet]
4517 *) SECURITY: Added compile-time and configurable limits for
4518 various aspects of reading a client request to avoid some simple
4519 denial of service attacks, including limits on maximum request-line
4520 size (LimitRequestLine), number of header fields (LimitRequestFields),
4521 and size of any one header field (LimitRequestFieldsize). Also added
4522 a configurable directive LimitRequestBody for limiting the size of the
4523 request message body. [Roy Fielding]
4525 *) Make status module aware of DNS and logging states, even if
4526 STATUS not defined. [Jim Jagielski]
4528 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
4530 *) Enhance mod_speling so that CheckSpelling can be used in
4531 <Directory> containers and .htaccess files. [Ken Coar]
4533 *) API: new ap_custom_response() function for hooking into the
4534 ErrorDocument mechanism at runtime [Doug MacEachern]
4536 *) API: new ap_uuencode() function [Doug MacEachern]
4538 *) API: scan_script_header_err_core() now "public" and renamed
4539 ap_scan_script_header_err_core() [Doug MacEachern]
4541 *) The 'status' module will now show the process pid's and their
4542 state even without full STATUS accounting. [Jim Jagielski]
4544 *) Restore the client IP address to the error log messages, this
4545 was lost during the transition from 1.2 to 1.3. Add a new
4546 function ap_log_rerror() which takes a request_rec * and
4547 formats it appropriately. [Dean Gaudet] PR#2661
4549 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
4550 whitespace in input lines -- including within quoted strings.
4552 but leading and trailing whitespace should continue to be
4553 stripped [Martin Kraemer]
4555 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
4556 the ugly use of an env. variable and use command-line args for
4557 alternate $PATH. Make more like advanced 'type's as well.
4560 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
4561 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
4562 <alain.st-denis@ec.gc.ca>] PR#2736
4564 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
4566 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
4567 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
4568 directory was renamed to src/os/os2/ for consistency.
4569 [Brian Havard, Ralf S. Engelschall]
4571 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
4572 files (here modules) against other DSO files (here shared libraries).
4573 This is done by determining a subset of LIBS which can be safely used for
4574 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
4575 disabled for all platforms to avoid problems with this (experimental)
4576 rule. But we provide it now for those people how ran into problems and
4577 want to came out by forcing linking against DSOs.
4578 [Ralf S. Engelschall] PR#2587
4580 *) Fix suEXEC start message: Has to be of `notice' level to really get
4581 printed together with the standard startup message because the `notice'
4582 level is handled special inside ap_log_error() for startup messages.

4592 handling loop so that the connection can be properly closed with
4593 lingering_close, thus avoiding a potential TCP reset that would
4594 cause the client to miss the HTTP error response. [Roy Fielding]
4596 *) One more portability fix for APACI shadow tree support: Swap order of awk
4597 and sed in top-level configure script to avoid sed fails on some
4598 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
4599 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729

4660 the TRACE method. This allows apache to TRACE along a chain of proxies
4661 up to a predetermined depth. [Martin Kraemer]
4663 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled

4703 *) Global renaming of C header files to both get rid of conflicts with third
4704 party packages and to again reach consistency:
4705 1. conf.h -> ap_config.h

4709 5. apctype.h -> ap_ctype.h
4710 Backward compatibility files for conf.h and compat.h were created.
4712 *) mod_mmap_static will no longer take action on requests unless at
4713 least one "mmapfile" directive is present in the configuration.
4714 This experimental module has to do some black magic to operate
4715 inside the current API and thus creates side-effects for other
4716 modules under some circumstances.

4726 if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341
4728 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
4729 TestCompile) instead of defining them manually in conf.h based on less
4730 accurate platform definitions. This way we no longer have to fiddle with
4731 OS-type and/or OS-version identifiers to discover whether a system header

4737 *) mod_setenvif (BrowserMatch* and friends) will now match a missing
4738 field with "^$". [Ken Coar]
4740 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
4741 modules to load their own modules dynamically. This improves mod_perl
4742 and mod_php3 when these modules are loaded dynamically into Apache.
4745 *) Cache a proxied request in the event that the client cancels the
4746 transfer, provided that the configured percentage of the file has
4747 already been transfered. It works for HTTP transfers only. The
4748 new configuration directive is called CacheForceCompletion.

4833 these are treated by Win32 as if they are ".." but are not detected by

4855 user. Package authors can use the --without-confadjust option to disable
4856 these configuration adjustments.

4865 as <IfModule>..</IfModule> sections) which can be used to skip or process
4866 contained commands dependend of ``-D PARAMETER'' options on the command
4867 line. This can be used to achieve logical conditions like <IfDefine
4868 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
4869 and thus especially can be used for conditionally loading DSO-based
4870 modules via LoadModule, etc. [Ralf S. Engelschall]

4881 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
4882 in top-level configure script to avoid sed fails on some platforms (for
4883 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
4884 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
4886 *) Improve performance of directory listings (mod_autoindex) by comparing
4887 integer keys (last-modified and size) as integers rather than converting
4888 them to strings first. Also use a set of explicit byte tests rather
4889 than strcmp() to check for parent directory-ness of an entry. Oh, and
4890 make sure the parent directory (if displayed) is *always* listed first
4891 regardless of the sort key. Overall performance winnage should be good
4892 in CPU time, instruction cache, and memory usage, particularly for large
4893 directories. [Ken Coar]
4895 *) Add a tiny but useful goody to APACI's configure script: The generation
4896 of a config.status script (as GNU Autoconf does) which remembers the used
4897 configure command and hence can be used to restore the configuration by
4898 just re-running this script or for remembering the configuration between
4900 [Ralf S. Engelschall]
4902 *) Add httpd -t (test) option for running configuration syntax tests only.
4903 If something is broken it complains and exits with a return code
4904 non-equal to 0. This can be used manually by the user to check the Apache
4905 configuration after editing and is also automatically used by apachectl
4906 on (graceful) restart command to make sure Apache doesn't die on restarts
4907 because of a configuration which is now broken since the last (re)start.
4908 This way `apachectl restart' can be used inside cronjobs without having

5050 spawn_child was obsoleted and moved to compat.h
5053 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
5054 programs: ap_spawn_child_err() is used and the Win32 case now uses
5055 CreateProcess() instead of a low-level execl() (which caused problems in
5056 the past under Win32).
5057 [Ralf S. Engelschall]
5059 *) A few cosmetics and trivial enhancements to APXS to make the
5060 generated Makefile more user friendly. [Ralf S. Engelschall]
5062 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5063 was updated to use the normal apache error processing, thereby allowing
5064 proxy errors to be treated by ErrorDocument's as well. For this
5065 purpose, a new module-to-core communication variable "error-notes"
5066 was introduced; the proxy (and possibly other modules) communicates
5067 its error text using this variable. Its content is copied to a new
5068 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5069 The old proxy special error routine ap_proxy_log_uerror()
5070 was replaced by regular ap_log_error() calls, many messages were made
5072 [Martin Kraemer] PR#494, 1259
5074 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
5077 *) Transform the configure message "You need root privileges for suEXEC"
5078 from a fatal error into a (more friendly) warning because the building
5079 ("make") of Apache we can allow, of course. Root privileges are needed
5080 only for the installation step ("make install"). So make sure the

5103 substitution takes place, for instance via the following rule:
5104 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often

5137 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
5138 [Ben Laurie] PR#2238
5140 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
5141 library), so CGI handling has been changed to use Win32 native handles
5142 instead of C file descriptors.
5143 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5145 *) The proxy cache would store an incorrect content-length in the cached
5146 file copy after a cache update. That resulted in repeated fetching
5147 of the original copy instead of using the cached copy.
5148 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5150 *) The Makefiles assumed that DSO files are build via $(LD). This
5151 is broken for two reasons: First we never defined at least LD=ld
5152 somewhere to make sure this works (it was silently assumed that most Make
5153 provide a built-in LD definition - ARGL!) and second using the generic LD
5154 variable is not the truth. Instead a special variable named LD_SHLIB is
5155 reasonable because although "ld" is usually the default, the command for
5156 building DSO files can be "libtool" or even "cc" on some systems.
5157 [Ralf S. Engelschall]
5159 *) Replace the AddVersionPlatform directive with ServerTokens which
5160 provides for more control over the format of the Server:
5161 header line. SERVER_SUBVERSION is no longer supported;
5162 all module should use the ap_add_version_component()
5163 API function instead. [Jim Jagielski]
5165 *) Support for the NCR MP/RAS 3.0
5166 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
5168 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
5169 not retrieved in src/Configure and thus was not useable.
5170 [Ralf S. Engelschall]
5172 *) Various Makefile consistency cleanups:
5173 - make OSDIR also automatically be relative to src/ like INCDIR
5174 - SUBDIRS is now generated in src/Makefile only and not in
5175 Makefile.config because it is a local define for this location.
5176 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5177 any Makefile but make sure that at least the "-K inline" is kept in
5179 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5180 - updated the dependencies theirself
5181 - removed not existing SHLIB variable from "clean" targets
5182 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5183 already exists and OBJS_PIC are also just plain objects and have not
5184 directly to do with "shared" things. The only difference is that they
5185 contain PIC. So OBJS_PIC is the more canonical name.
5186 - Updated the Makefile-dependency lines for OBJS_PIC
5187 - Removed the Makefile-dependency line in Configure to avoid double
5189 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5190 of xxx.lo as GNU libtool does with its PIC objects
5191 - reduce local complexity in modules Makefile.tmpl by moving the last
5192 existing target "depend" to the generation section in Configure, too.
5193 - removed the historical $(SPACER) which was used in the past together
5194 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5195 is no longer needed.
5196 - force the build and run of the gen_xxx programs under main/ as the
5197 first step before building the objects because it looks cleaner
5198 [Ralf S. Engelschall]
5200 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
5203 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
5206 *) WIN32: Don't force ISAPI headers to finish with \n.
5207 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5209 *) When opening "configuration" files (like httpd.conf, htaccess
5210 and htpasswd), Apache will not allow them to be non-/dev/null
5211 device files. This closes a DoS hole. At the same time,
5212 we use ap_pfopen to open these files to handle timeouts.
5213 [Jim Jagielski, Martin Kraemer]
5215 *) Apache will now log the reason its httpd children exit if they exit
5216 due to an unexpected signal. (It requires a new porting define,
5217 SYS_SIGLIST, which if defined should point to a list of text
5218 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5220 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5221 like WIN32. Before, Win32 CGI's could have had sporadic failures
5222 if a chdir call from one thread was made between another chdir call
5223 and a spawn in another thread. So, for now don't chdir for CGI scripts
5224 in WIN32. The current CGI "spec" is unclear as to whether it's
5225 necessary. Long-term fix is to either serialize the chdir/spawn combo
5226 or use WIN32 native calls to spawn a process. This temp fix was
5227 necessary to remove this as a showstopper for 1.3's release.
5230 *) Cleanup the suEXEC support in APACI and make it more safe:
5231 1. Add big fat hint in INSTALL about risks and to read the
5232 htdocs/manual/suexec.html document before using the suexec-related
5234 2. Make sure the user has at least provided one --suexec-xxxx option
5235 (specifies suEXEC parameters) in addition to --enable-suexec option.
5236 If only --enable-suexec is given APACI stops with a hint to INSTALL
5237 and htdocs/manual/suexec.html documents.
5238 3. Provide two additional --suexec-xxxx options to make the suEXEC
5239 configuration complete (especially for package maintainers who else
5240 had to patch the source tree) by providing ways to configure minimal
5241 UID/GID and safe PATH, too.
5242 [Ralf S. Engelschall]
5244 *) Cleanup of the `configure --shadow' process:
5245 - make sure the configure script creates its temporary files in the
5246 shadow tree to avoid conflicts with parallel configure runs
5247 - removed unnecessary option "-r" from "rm" call for Makefiles
5248 - make sure the configure scripts creates the shadow-wrapper Makefile
5249 only when no shadow trees already exists
5250 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5251 when no more shadow trees exists
5252 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5253 as fast (in the past it needed 70sec, now it runs just 38sec)
5254 - make sure CVS does not complain about the created files
5255 Makefille.<gnutriple> and directories src.<gnutriple>
5256 [Ralf S. Engelschall]
5258 *) Added the ap_add_version_component() API routine and the
5259 AddVersionPlatform core directive. The first allows modules to
5260 declare themselves in the Server response header field value,
5261 augmenting the SERVER_SUBVERSION define in the Configuration file
5262 with run-time settings (more useful in a loadable-module environment).
5263 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5264 into the server version string. [Ken Coar] PR#2056
5266 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5269 *) Emit the "Accept-Range" header for the default handler.
5270 [Brian Behlendorf] PR#1464
5272 *) Add a note to httpd.conf-dist that apache will on some systems fail
5273 to start when the Group # is set to a negative or large positive value.
5276 *) Make sure the module execution order is correct even when some modules
5277 are loaded under runtime (`LoadModule') via the DSO mechanism:
5278 1. The list of loaded modules is now a dynamically allocated one
5279 and not the original statically list from modules.c
5280 2. The loaded modules are now correctly setup by LoadModule for
5281 later use by the AddModule command.
5282 3. When the DSO mechanism for modules is used APACI's `install'
5283 target now enables all created `LoadModule' lines per default because
5284 this is both already expected by the user _and_ needed to avoid
5285 confusion with the next point and reduces the Makefile.tmpl complexity
5286 4. When the DSO mechanism for modules is used, APACI's `install'
5287 target now additionally makes sure the module list is reconstructed
5288 via a complete `ClearModuleList+AddModule...' entry.
5289 5. The support tool `apxs' now also makes sure an AddModule command
5290 is added in addition to the LoadModule command.
5291 6. The modules.c generation was extended to now contain two
5292 comments to make sure no one is confused by the confusing terminology
5293 of loading/linking (we use load=link+load & link=activate instead of
5294 the obvious load=activate & link=link :-( )
5295 This way now there is no longer a difference under execution time between
5296 statically and dynamically linked modules.
5297 [Ralf S. Engelschall]
5299 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
5300 Big Symbol Renaming. [Ralf S. Engelschall]
5302 *) Add a comment to mod_example.c showing the format of a FLAG command
5305 *) Standardized the time format in mod_status to match that of other
5306 places in the code (e.g. DATE_GMT). PR#1551
5308 *) Fix handling of %Z in timefmt strings for those platforms with no time
5309 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5312 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5313 feature compatible with 'UseCanonicalName off' by changing
5314 r->server->server_hostname to ap_get_server_name(). And I changed some
5315 functions which use r->server->port to use ap_get_server_port() instead,
5316 because if there's no Port directive in the config r->server->port is 0.
5319 *) get/set_module_config are trivial enough to be better off inline. Worth
5320 1.5% performance boost. [Dean Gaudet]
5322 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5323 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5326 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5327 the task environment to the unprivileged User id. Otherwise CGI scripts
5328 would have a way to gain super user access. [Martin Kraemer]
5330 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5331 absolute path, only log base name of logging source as is done
5332 in unix. [Martin Kraemer]
5334 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5335 the encoding type from the Accept-Encoding header (if it's there)
5336 and use it in the response, as that's probably what it'll be expecting.
5337 [Ronald.Tschalaer@psi.ch]
5339 *) Fix to mod_alias: translate_alias_redir is dealing with
5340 a URI, not a filename, so the check for drive letters for win32
5341 and emx is not necessary. [Dean Gaudet]
5343 *) WIN32: Allow .cmd as an executable extension.
5344 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
5346 *) Make Apache header files, and some variables, C++ friendly.
5347 [Michael Anderson's <mka@redes.int.com.mx>]
5349 *) Child processes can now "signal" (by exiting with a status
5350 of APEXIT_CHILDFATAL) the parent process to abort and
5351 shutdown the server if the error in the child process was
5352 fatal enough. [Jim Jagielski]
5354 *) mod_autoindex's find_itme() was sensitive to MIME type case.
5355 [Jim Jagielski] PR#2112
5357 *) Make sure the referer_log and agent_log entries in the default httpd.conf
5358 file are also adjusted for the actual relative installation paths.
5359 [Ralf S. Engelschall] PR#2175
5361 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
5363 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
5366 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5367 Additionally the checks for finding the vendor DSO library were moved
5368 from mod_so.c to Configure because first it needs $PLAT etc. and second
5369 mod_so already uses an abstraction layer and does not fiddle with the
5370 vendor functions itself.
5371 [Jens-Uwe Mager, Ralf S. Engelschall]
5373 *) PORT: Some optimization defines for NetBSD
5374 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
5376 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
5377 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
5379 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
5380 AIX variants should work fine, too. Even AIX 3.x should work). This is
5381 accomplished by using the free DSO emulation code from Jens-Uwe Mager
5382 which we put into a os/unix/os-dso-aix.c file.
5383 [Ralf S. Engelschall]
5385 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
5386 that we should use NET_SIZE_T == int but the include files force size_t.
5387 [Ralf S. Engelschall]
5389 *) Fix two bugs in select() handling in http_main.c.
5392 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
5393 is unset (as it is in situations like timeouts) where it is unclear
5394 whether errno is set or not. [Martin Kraemer]
5396 *) Just having APACI's localstatedir is too general and not enough for most
5397 of the systems. 1.3b6 again required manual APACI patches by package
5398 maintainers from RedHat and FreeBSD because for their filesystem layout a
5399 little bit more flexibility in configuring the paths is needed. Hence we
5400 provide three additional configure options (--runtimedir, --logfiledir,
5401 --proxycachedir) which now can be used for more granular adjustments if
5402 --localstatedir is not enough to fit the particular needs. As a nice
5403 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
5404 [Ralf S. Engelschall]
5406 *) Make the install root for "make install" in APACI's Makefile overrideable
5407 by package authors. This way we are even more friendly to package
5408 maintainers (especially Debian and RedHat) who build for the real prefix
5409 via "configure --prefix=/<real>" but use a different local prefix via
5410 "make root=/tmp/apache install" for rolling the package without bristling
5411 the target location on their system.
5412 [Ralf S. Engelschall]
5414 *) Workaround sed limitations in APACI's configure script by now
5415 substituting in chunks of 50 commands (because for instance HPUX's vendor
5416 sed has a limit of max. 98 commands)
5417 [Ralf S. Engelschall] PR#2136
5419 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
5420 [Ralf S. Engelschall] PR#2140
5422 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
5423 RENAMING process because they are defined as pre-processor macros instead
5424 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
5425 [Ralf S. Engelschall]
5427 *) Workaround braindead AWK's when generating ap_config.h: The split() and
5428 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
5429 [Ralf S. Engelschall] PR#2139
5431 *) Various bugfixes and cleanups for the APACI configure script:
5432 o fix IFS handling for _nested_ situation
5433 o fix Perl interpreter search: take first one found instead of last one
5434 o fix DSO consistency check
5435 o print error messages to stderr instead of stdout
5436 o add install-quiet for --shadow situation to Makefile stub
5437 o reduce complexity by avoiding sed-hacks for rule and module list loops
5438 [Ralf S. Engelschall]
5440 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
5442 *) Make sure the input field separator (IFS) shell variable is explicitly
5443 initialized correctly before _every_ `for' loop and also restored after
5444 the loops. [Ralf S. Engelschall]
5446 *) Make sure that "make install" doesn't overwrite the `mime.types' and
5447 `magic' files from an existing Apache installation. Because people often
5448 customize these for own MIME and content types.
5449 [Ralf S. Engelschall]
5451 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
5452 [Peter Galbavy, Ralf S. Engelschall] PR#2109
5454 *) Fix the path to the ScoreBoardFile in the install-config target, too.
5455 [Ralf S. Engelschall] PR#2105
5457 *) Let "configure" clear out the users parameters (provided as shell
5458 variables) to avoid side-effects in "src/Configure" when the user
5459 exported them (which is not needed, but some users do it).
5460 [Ralf S. Engelschall] PR#2101
5462 *) Provide backward compatibility from some old src/Configuration.tmpl
5463 parameter names to the canonical Autoconf-style shell variable names. For
5464 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
5465 but a hint message is displayed. [Ralf S. Engelschall]
5467 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
5468 CGI scripts from an existing Apache installation.
5469 [Ralf S. Engelschall, Jim Jagielski] PR#2084
5471 *) Make `configure --compat' more "compatible" by first
5472 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
5473 second by making sure the "avoid-bristling-suffix" /apache is not
5474 appended to sysconfdir, datadir, localstatedir and includedir when
5475 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
5477 *) NeXT required strdup() in support/logresolve.c
5478 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
5480 *) AIX required sys/select.h in support/ab.c
5481 [Jens Schleusener <Jens.Schleusener@dlr.de>] PR#2081
5483 *) Fix the path to the MimeMagicFile in the install-config target, too.
5484 [Ralf S. Engelschall] PR#2089
5486 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
5488 *) If you start apache with the -S command line option it will dump
5489 out the parsed vhost settings. This is useful for folks trying
5490 to figure out what is wrong with their vhost configuration.
5491 (Other dumps may be added in the future.) [Dean Gaudet]
5493 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
5494 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
5497 *) Because /usr/local/apache is the default prefix the ``configure
5498 --compat'' option no longer has to set prefix, again. This way the
5499 --compat option honors a leading --prefix option. [Lars Eilebrecht]
5501 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
5502 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
5503 to avoid "discard const" warnings. [Ralf S. Engelschall]
5505 *) If a specific handler is set for a file yet the request still
5506 ends up being handled by the default handler, log an error
5507 message before handling it. This catches things such as trying
5508 to use SSIs without mod_include enabled. [Marc Slemko]
5510 *) Fix error logging for the startup case where ap_log_error() still uses
5511 stderr as the target. Now the default log level is honored here, too.
5512 [Ralf S. Engelschall]
5514 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
5515 long" errors when generating the MODULES entry for src/Makefile
5516 [Ben Hyde, Ralf S. Engelschall]
5518 *) Make sure src/Configure doesn't complain about the old directory
5519 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
5521 Changes with Apache 1.3b6
5523 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
5525 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
5526 interface via the similar but proprietary HP/UX shl_xxx-style system
5527 calls. [Ralf S. Engelschall]
5529 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
5530 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
5531 Make. [Ralf S. Engelschall]
5533 *) ++++ THE BIG SYMBOL RENAMING ++++
5534 To avoid symbol clashes with third-party code compiled into the server,
5535 we globally applied the prefix "ap_" to the following classes of
5537 - Apache provided general functions (e.g., ap_cpystrn)
5538 - Public API functions (e.g., palloc, bgets)
5539 - Private functions which we can't make static (because of
5540 cross-object usage) but should be (e.g., new_connection)
5541 For backward source compatibility a new header file named compat.h was
5542 created which provides defines for the old symbol names and can be used
5543 by third-party module authors.
5546 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
5547 problem under SVR4 is that there is no command flag to force the linker
5548 to export the global symbols of the httpd executable therewith they are
5549 available to the DSO's. Instead of problematic hacks like creating a
5550 dummy.so file (containing dummy references to all global symbols) the
5551 httpd binary is linked against, we use a clean trick stolen from Perl 5:
5552 Placing the Apache core code itself into a DSO library named libhttpd.so.
5553 This way the global symbols _HAVE_ to be exported and thus are available
5554 to any manually loaded DSO's under runtime. To reduce the impact to the
5555 user to null we go even further and create a stub httpd executable which
5556 automatically keeps track of the DSO library loading itself and thus
5557 hides the complete mechanism from the user. Although the generation of
5558 this DSO library is automatically triggered for platforms which
5559 essentially need it (mostly all SVR4-derivates) it can be also enabled
5560 manually via the Rule SHARED_CORE. This can be interesting in the future
5561 where we perhaps exploit this libhttpd.so mechanism for providing nifty
5562 features like graceful upgrades, or whatever.
5563 [Ralf S. Engelschall, Martin Kraemer]
5565 *) Build the libraries before building the rest of the tools. [Ben Hyde]
5567 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
5568 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
5569 conventions while "clean" removes only stuff created by "all" targets,
5570 "distclean" additionally removes the stuff from the configuration
5571 process. This way "make distclean" (hence the name) provides a fresh
5572 source tree as it was for distribution.
5573 [Ralf S. Engelschall]
5575 *) Allow top-level (APACI) Makefile to break on build errors
5576 the same way the src/ subtree Makefiles breaks on them by replacing the
5577 initial APACI sed-subdir-display-kludge with a more clean
5578 variable-passing-solution: variable SDP can optionally hold the subdir
5579 prefix which is consistently used for displaying the subdir movement.
5580 This way even the top-level Makefile can stop correctly on errors as the
5581 user expects. [Ralf S. Engelschall]
5583 *) Fixed ordering of argument checks for RewriteBase directive.
5584 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
5586 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
5587 indicating that a module is being compiled for dynamic loading. Also
5588 remove #define IS_MODULE from modules and add SHARED_MODULE define
5589 to the mak/dsp files. [Alexei Kosut]
5591 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
5592 since we are now logging APLOG_WARNING by default. [Roy Fielding]
5594 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
5596 *) Add documentation file and src/Configuration.tmpl entry for the
5597 experimental mod_mmap_static module. Because although it is and marked as
5598 an experimental one it is distributed and thus should be documented and
5599 prepared for configuration the same way as all others modules.
5600 [Ralf S. Engelschall]
5602 *) Add query (-q) option to apxs support tool to be able to manually query
5603 specific settings from apxs. This is needed for instance when you
5604 manually want to access Apache's header files and you need to assemble
5605 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
5606 [Ralf S. Engelschall]
5608 *) Now src/Configure uses a fallback strategy for the shared object support
5609 on platforms where no explicit information is available: If a Perl
5610 installation exists we ask it about its shared object support and if it's
5611 the dlopen-style one we shamelessly guess the compiler and linker flags
5612 for creating shared objects from Perls knowledge. Of course, the user is
5613 warning about what we are doing and informed that he should send us
5614 the guessed flags when they work. [Ralf S. Engelschall]
5616 *) Provide APACI --without-support option to be able to disable the build
5617 and installation of the support tools from the src/support/ area.
5618 Although its useful to have these installed per default we should provide
5619 a way to compile and install without them for backward-compatibility.
5620 [Ralf S. Engelschall]
5622 *) Add of the new APache eXtenSion (apxs) support tool for building and
5623 installing modules into an _already installed_ Apache package through the
5624 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
5625 this approach actually doesn't need the Apache source tree. The
5626 (APACI-installed) server package is enough, because this now includes the
5627 Apache C header files (PREFIX/include) and the new APXS tool
5628 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
5629 module authors to build their Apache modules _OUTSIDE_ the Apache source
5630 tree while avoiding them to fiddle around with the totally platform
5631 dependend way of compiling DSO files. The tool supports all ranges of
5632 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
5633 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
5634 on-the-fly generate a minimalistic Makefile and sample module for the
5635 first step to provide both a quick success event and to demonstrate the
5636 APXS mechanism to module authors. [Ralf S. Engelschall]
5638 *) Fix core dumps in use of CONNECT in proxy.
5639 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
5641 *) Modify the log directives in httpd.conf-dist files to use CustomLog
5642 so that users have examples of how CustomLog can be used.
5645 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
5646 the Apache distribution tree. Until Apache 1.3 there was no real
5647 out-of-the-box batch-capable build and installation procedure for the
5648 complete Apache package. This is now provided by a top-level "configure"
5649 script and a corresponding top-level "Makefile.tmpl" file. The goal is
5650 to provide a GNU Autoconf-style frontend which is capable to both drive
5651 the old src/Configure stuff in batch and additionally installs the
5652 package with a GNU-conforming directory layout. Any options from the old
5653 configuration scheme are available plus a lot of new options for flexibly
5654 customizing Apache. [Ralf S. Engelschall]
5656 *) The floating point ap_snprintf code wasn't threadsafe.
5657 Had to remove the HAVE_CVT macro in order to do threadsafe
5658 calling of the ?cvt() floating point routines. [Dean Gaudet]
5660 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
5662 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
5663 [Jim Jagielski] PR#1901
5665 *) BUG: Configure was using TCC and CC inconsistently. Make sure
5666 Configure knows which CC we are using. [Jim Jagielski]
5668 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
5669 was defined in a parent directory. [Lars Eilebrecht]
5671 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5672 a generic printf-style routine that can call arbitrary output
5673 routines. Use this to replace http_bprintf.c. Add new routines
5674 psprintf(), pvsprintf() which allocate the exact amount of memory
5675 required for a string from a pool. Use psprintf() to clean up
5676 various bits of code which used ap_snprintf()/pstrdup().
5679 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5680 ap_snprintf() has different semantics and formatting codes than
5681 snprintf(). [Dean Gaudet]
5683 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5684 is necessary on at least Solaris where the /etc/rc?.d scripts
5685 are run with these signals ignored, and "SIG_IGN" settings are
5686 maintained across exec().
5687 [Rein Tollevik <reint@sys.sol.no>] PR#2009
5689 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
5690 used instead of lstat() and thus this flag didn't work as expected.
5691 [Rein Tollevik <reint@sys.sol.no>] PR#2010
5693 *) Fix the proxy pass-through feature of mod_rewrite for the case of
5694 existing QUERY_STRING now that mod_proxy was recently changed because of
5695 the new URL parsing stuff. [Ralf S. Engelschall]
5697 *) A few changes to scoreboard definitions which helps gcc generate
5698 better code. [Dean Gaudet]
5700 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
5701 be a signed bitfield. So mark a few bitfields as signed to
5702 ensure correct code. [Dean Gaudet]
5704 *) The default for HostnameLookups was changed to Off, but there
5705 was a problem and it wasn't taking effect. [Dean Gaudet]
5707 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
5710 *) After a SIGHUP the listening sockets in the parent weren't
5711 properly marked for closure on fork().
5712 [Jürgen Keil <jk@tools.de>] PR#2000
5714 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5715 therefore not exposed to %2F -> '/' translations and 2) the request
5716 is a proxy request, so we're not dealing with a local resource anyway.
5717 Without this, the proxy would fail to work for any URL's with
5718 %2f in them (occurs quite often in
5719 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
5721 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
5723 *) Make the shared object compilation command more portable by avoiding
5724 the direct combination of `-c' & `-o' which is not honored by some
5725 compilers like UnixWare's cc. [Ralf S. Engelschall]
5727 *) WIN32: the proxy was creating filenames missing the last four
5728 characters. While this normally doesn't stop anything from
5729 working, it can result in extra collisions.
5730 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
5732 *) Now mod_proxy uses the response string (in addition to the response status
5733 code) from the already used FTP SIZE command to setup the Content-Length
5734 header if available. [Ralf S. Engelschall] PR#1183
5736 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5737 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
5738 name was really too generic, added documentation for this directive to
5739 the mod_proxy.html and corrected the hyperlink to it in the
5740 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
5742 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
5743 faster [Martin Kraemer]
5745 *) Make Configure die when you give it an unknown command switch.
5748 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5749 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5750 and per default compiled support programs have manual pages - just to
5751 document our stuff a little bit more and to be able to do really
5752 Unix-like installations ;-) [Ralf S. Engelschall]
5754 *) Major cleanups to the Configure script to make it and its generated
5755 Makefiles again readable and maintainable: add SRCDIR option, removed
5756 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5757 generated sections, consequently added Makefile headers with inheritance
5758 information, added subdir movement messages for easier following where
5759 the build process currently stays (more verbose then standard Make, less
5760 verbose than GNU make), same style to comments in the Configure script,
5761 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5763 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5764 from the ZeusBench benchmarking program and can be used to determine the
5765 response performance of an Apache installation. This version is
5766 officially licensed with Zeus Technology, Ltd. See the license agreement
5767 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
5768 [Ralf S. Engelschall]
5770 *) API: Various core functions that are definately not part of the API
5771 have been made static, and a few have been marked API_EXPORT. Still
5772 more have been marked CORE_EXPORT and are not intended for general
5773 use by modules. [Doug MacEachern, Dean Gaudet]
5775 *) mod_proxy was not clearing the Proxy-Connection header from
5776 requests; now it does. This did not violate any spec, however
5777 causes poor interactions when you are talking to remote proxies.
5778 [Marc Slemko] PR#1741
5780 *) Various cleanups to the command line interface and manual pages.
5781 [Ralf S. Engelschall]
5783 *) cfg_getline() was not properly handling lines that did not end
5784 with a line termination character. [Marc Slemko] PR#1869, 1909
5786 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5788 *) Clean up some undocumented behavior of mod_setenvif related to
5789 "merging" two SetEnvIf directives when they match the same header
5790 and regex. Document that mod_setenvif will perform comparisons in
5791 the order they appear in the config file. Optimize mod_setenvif by
5792 doing more work at config time rather than at runtime.
5795 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5796 to allow for modules to overrule them and to reduce redefinition
5797 warnings [Jim Jagielski]
5799 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5802 *) Making the hard-coded cross-module function call mime_find_ct() (from
5803 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5804 checking is really called even for proxy requests except for URLs with
5805 HTTP schemes (because there we can optimize by not running the type
5806 checking hooks due to the fact that the proxy gets the MIME Content-type
5807 from the remote host later). This change cleans up mod_mime by removing
5808 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5809 especially unbundles mod_proxy and mod_mime. This way they both now can
5810 be compiled as shared objects and are no longer tied together.
5811 [Ralf S. Engelschall]
5813 *) util.c cleanup and speedup. [Dean Gaudet]
5815 *) API: Clarification, pstrndup() will always copy n bytes of the source
5816 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5818 *) Mark module command_rec and handler_rec structures const so that they
5819 end up in the read-only data section (and are friendlier to systems
5820 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5822 *) Add check to the "Port" directive to make sure the specified
5823 port is in the appropriate range. [Ben Hyde]
5825 *) Performance improvements to invoke_handler().
5826 [Dmitry Khrustalev <dima@bog.msu.su>]
5828 *) Added support for building shared objects even for library-style modules
5829 (which are built from more than one object file). This now provides the
5830 ability to build mod_proxy as a shared object module. Additionally
5831 modules like mod_example are now also supported for shared object
5832 building because the generated Makefiles now no longer assume there is at
5833 least one statically linked module. [Ralf S. Engelschall]
5835 *) API: Clarify usage of content_type, handler, content_encoding,
5836 content_language and content_languages fields in request_rec. They
5837 must always be lowercased; and the strings pointed to shouldn't
5838 be modified (you must copy them to modify them). Fix a few bugs
5839 related to this. [Dean Gaudet]
5841 *) API: Clarification: except for RAW_ARGS, all command handlers can
5842 treat the char * parameters as permanent, and modifiable. There
5843 is no need to pstrdup() them. Clean up some needless pstrdup().
5846 *) Now mod_so keeps track of which module shared objects with which names
5847 are loaded and thus avoids multiple loading and unloading and irritating
5848 error_log messages. [Ralf S. Engelschall]
5850 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5851 environment variable in the apache core. But that tweaking interferes
5852 with mod_setenv. So don't tweak if the user has specified an explicit
5853 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
5855 *) rputs() did not calculate r->sent_bodyct properly.
5856 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
5858 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
5859 name, or left unset if this value is unavailable. Apache was setting
5860 it to the IP address when unavailable.
5861 [Tony Finch <fanf@demon.net>] PR#1925
5863 *) Various improvements to the configuration and build support for compiling
5864 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5865 OSF1 support with GCC and vendor compilers was added. This way shared
5866 object support is now provided out-of-the-box for FreeBSD, Linux,
5867 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5868 [Ralf S. Engelschall]
5870 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5871 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5872 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5874 *) Fix one more special locking problem for RewriteMap programs in
5875 mod_rewrite: According to the documentation of flock(), "Locks are on
5876 files, not file descriptors. That is, file descriptors duplicated
5877 through dup(2) or fork(2) do not result in multiple instances of a lock,
5878 but rather multiple references to a single lock. If a process holding a
5879 lock on a file forks and the child explicitly unlocks the file, the
5880 parent will lose its lock.". To overcome this we have to make sure the
5881 RewriteLock file is opened _AFTER_ the childs were spawned which is now
5882 the case by opening it in the child_init instead of the module_init API
5883 hook. [Ralf S. Engelschall] PR#1029
5885 *) Change to Location and LocationMatch semantics. LocationMatch no
5886 longer lets a single slash match multiple adjacent slashes in the
5887 URL. This change is for consistency with RewriteRule and
5888 AliasMatch. Multiple slashes have meaning in URLs that they do
5889 not have in (some) filesystems. Location on the other hand can
5890 be considered a shorthand for a more complicated regex, and it
5891 does match multiple slashes with a single slash -- which is
5892 also consistent with the Alias directive.

5895 *) Fix bug with mod_mime_magic causing certain files, including files
5896 of length 0, to result in no response from the server.
5899 *) The Configure script now generates src/include/ap_config.h which
5900 contains the set of defines used when Apache is compiled on a platform.
5901 This file can then be included by external modules before including
5902 any Apache header files in case they are being built separately from
5903 Apache. Along with this change, a couple of minor changes were
5904 made to make Apache's #defines coexist peacefully with any autoconf
5905 defines an external module might have. [Rasmus Lerdorf]
5907 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
5908 but without any RewriteXXXXX directives. Here mod_rewrite is given no
5909 chance by the API to initialize its per-server configuration and thus
5910 receives the wrong one from the main server. This is now avoided by
5911 remembering the server together with the config structure while
5912 configuring and later assuming there is no config when we see a
5913 difference between the remembered server and the one calling us.
5914 [Ralf S. Engelschall] PR#1790
5916 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
5917 is automatically disabled under configure time when the dbm_xxx functions
5918 are not available. Second, two heavy source code errors in the DBM
5919 support code were fixed. This makes DBM RewriteMap's usable again after
5920 a long time of brokenness. [Ralf S. Engelschall] PR#1696
5922 *) Now all configuration files support Unix-style line-continuation via
5923 the trailing backslash ("\") character. This enables us to write down
5924 complex or just very long directives in a more readable way. The
5925 backslash character has to be really the last character before the
5926 newline and it has not been prefixed by another (escaping) backslash.

5938 *) WIN32: Preserve trailing slash in canonical path (and hence
5939 in PATH_INFO). [Paul Sutton, Ben Laurie]
5941 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
5942 depending on the rev of Solaris and what mixture of modules
5943 are in use. So it has been disabled, and Solaris is back to
5944 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
5945 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
5946 up static content only servers. Or it may fail unpredictably.

5949 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
5952 *) API: Rewrite of absoluteURI handling, and in particular how
5953 absoluteURIs match vhosts. Unless a request is a proxy request, a
5954 "http://host" url is treated as if a similar "Host:" header had been
5955 supplied. This change was made to support future HTTP/1.x protocols
5956 which may require clients to send absoluteURIs for all requests.
5958 In order to achieve this change subtle changes were made to the API. In a
5959 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
5960 that the unmodified uri can be retrieved easily. r->proxyreq is not set
5961 by the core, modules must set it during the post_read_request or
5962 translate_names phase.
5964 Plus changes to the virtualhost test suite for absoluteURI testing.
5966 This fixes several bugs with the proxy proxying requests to vhosts
5967 managed by the same httpd.
5970 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
5971 code from mod_rewrite. The vhost matching is now performed by a
5972 globally available function matches_request_vhost(). [Dean Gaudet]

5988 *) API: A new source module main/util_uri.c; It contains a routine
5989 parse_uri_components() and friends which breaks a URI into its component
5990 parts. These parts are stored in a uri_components structure called
5991 parsed_uri within each request_rec, and are available to all modules.
5992 Additionally, an unparse routine is supplied which re-assembles the URI
5993 components back to an URI, optionally hiding the username:password@ part
5994 from ftp proxy requests, and other useful routines. Within the structure,
5995 you find on a ready-for-use basis:
5996 scheme; /* scheme ("http"/"ftp"/...) */
5997 hostinfo; /* combined [user[:password]@]host[:port] */
5998 user; /* user name, as in http://user:passwd@host:port/ */
5999 password; /* password, as in http://user:passwd@host:port/ */
6000 hostname; /* hostname from URI (or from Host: header) */
6001 port_str; /* port string (integer representation is in "port") */
6002 path; /* the request path (or "/" if only scheme://host was given) */
6003 query; /* Everything after a '?' in the path, if present */
6004 fragment; /* Trailing "#fragment" string, if present */
6005 This is meant to serve as the platform for *BIG* savings in
6006 code complexity for the proxy module (and maybe the vhost logic).
6009 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6010 ${map:key}) available for all location where a string is created in
6011 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6012 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6013 possible expansions are consequently usable at all string creation
6014 locations. [Ralf S. Engelschall]
6016 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6017 and not 1) and the per-virtual-server merging of directives. Now all
6018 directives except `RewriteEngine' and `RewriteOption' are either
6019 completely overridden (default) or completely inherited (when
6020 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6026 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause

6029 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6030 (like SunOS and FreeBSD) which don't accept the locking of pipes
6031 directly. A new directive RewriteLock is introduced which can be used to
6032 setup a separate locking file which then is used for synchronization.

6050 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6051 type but with a special post-processing for the looked-up value: It
6052 parses it into alternatives according to `|' chars and then only one
6053 particular alternative is chosen randomly (this is an essential
6054 functionality needed for balancing between backend-servers when using
6055 Apache as a Reverse Proxy. The looked up value here is a list of
6056 servers). Second, `int' with the built-in maps named `tolower' and
6057 `toupper' which can be used to map URL parts to a fixed case (this is an
6058 essential feature to fix the case of server names when doing mass
6059 virtual-hosting with the help of mod_rewrite instead of using
6060 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6061 Jay Soffian <jay@cimedia.com>] PR#1631
6063 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6064 This directive lets Apache adjust the URL in Location-headers on HTTP
6065 redirect responses sent by the remote server. This way the virtually
6066 mapped area is no longer left on redirects and thus by-passed which is
6067 especially essential when running Apache as a reverse proxy.

6215 *) Yet another rearrangement of the source tree.. now all the common
6216 header files are in the src/include directory. The -Imain -Iap
6217 references in Makefiles have been changed to the simpler -Iinclude
6218 instead. In addition to simplifying the build a little bit, this
6219 also makes it clear when a module is referencing something in a
6220 other than kosher manner (e.g., the proxy including mod_mime.h).
6221 Module-private header files (the proxy, mod_mime, the regex library,
6222 and mod_rewrite) have not been moved to src/include; nor have
6223 the OS-abstraction files. [Ken Coar]

6230 MAKE_TABLE_PROFILE which can help discover make_table()
6231 calls that use too small an initial guess, see alloc.c.
6234 *) Options and AllowOverride weren't properly merging in the main
6235 server setting inside vhosts (only an issue when you have no
6236 <Directory> or other section containing an Options that affects
6237 a request). Options +foo or -foo in the main_server wouldn't
6238 affect the main_server's lookup defaults. [Dean Gaudet]

6252 *) mod_unique_id was erroneously generating a second unique id when
6253 an internal redirect occured. Such redirects occur, for example,
6254 when processing a DirectoryIndex match. [Dean Gaudet]
6256 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6257 of the key and value. But in many cases this is not required
6258 because the key/value is a constant, or the value has been built
6259 by pstrcat() or other similar means. New routines table_addn,
6260 table_mergen, and table_setn have been added to the API, these
6261 routines do not pstrdup() their arguments. The core code and
6262 standard modules were changed to take advantage of these routines.
6263 The resulting server is up to 20% faster in some situations.
6265 Note that it is easy to get code subtly wrong if you pass a key/value
6266 which is in a pool other than the pool of the table. The only
6267 safe thing to do is to pass key/values which are in the pool of
6268 the table, or in one of the ancestors of the pool of the table.
6269 i.e. if the table is part of a subrequest, a value from the main
6270 request's pool is OK since the subrequest pool is a sub_pool of the
6271 main request's pool (and therefore has a lifespan at most as long as
6272 the main pool). There is debugging code which can detect improper
6273 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
6274 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
6276 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
6277 which don't exist on disk more gracefully; handles vhosts properly.
6278 Update documentation to reflect the code -- if there's no
6279 MimeMagicFile directive then the module is not enabled.
6282 *) PORT: Some older *nix dialects cannot automatically start scripts
6283 which begin with a #! interpreter line (the shell starts the scripts
6284 appropriately on these platforms). Apache now supports starting of
6285 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.

6289 *) API: "typedef array_header table" removed from alloc.h, folks should
6290 have been writing to use table as if it were an opaque type, but even
6291 some standard modules got this wrong. By changing the definition
6292 to "typedef struct table table" module authors will receive compile
6293 time warnings that they're doing the wrong thing. This change
6294 facilitates future changes with more sophisticated table
6295 structures. Specifically, module authors should be using table_elts()
6296 to get access to an array_header * for the table. [Dean Gaudet]
6298 *) API: Renamed new_connection() to avoid namespace collision with LDAP
6299 library routines. [Ken Coar, Rasmus Lerdorf]
6301 *) WIN32: mod_speling is now available on the Win32 platform.
6304 *) For clarity the following compile time definition was changed:
6306 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6308 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6309 and not be a general notice that the OS has mmap(). Now the
6310 HAVE_MMAP/SHMGET #defines strictly are informational that the
6311 OS has that method of shared memory; the type to use for
6312 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6313 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6314 determine if shared memory is available and allows Apache
6315 to determine the best method to use for the scoreboard.

6383 but before the header file contents. [John Van Essen <jve@gamers.org>]
6386 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6387 only an issue on systems without a MAXDNAME define or where
6388 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6390 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6391 is used to read various types of files such as htaccess and
6392 htpasswd files. [Marc Slemko]
6394 *) SECURITY: Ensure that the buffer returned by ht_time is always
6395 properly null terminated. [Marc Slemko]
6397 *) The "Connection" header could be sent back with multiple "close"
6398 tokens. Not an error, but a waste.
6399 [Ronald.Tschalaer@psi.ch] PR#1683
6401 *) mod_rewrite's RewriteLog should behave like mod_log_config, it

6404 *) "basic" auth needs a case-insensitive comparison.
6405 [Ronald.Tschalaer@psi.ch] PR#1666
6407 *) For maximum portability, the environment passed to CGIs should
6408 only contain variables whose names match the regex
6409 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
6410 underscores over any character outside the regex. This
6411 affects HTTP_* variables, in a way that should be backward
6412 compatible for all the standard headers; and affects variables
6413 set with SetEnv/BrowserMatch and similar directives.
6416 *) mod_speling returned incorrect HREF's when an ambigous match

6452 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6453 including fixing a possible buffer overflow. [Dean Gaudet]

6456 (connections are not dropped). Code can handle graceful restarts
6457 (but there is as yet no way to signal this to Apache). Various
6458 other cleanups. [Paul Sutton]
6460 *) The aplog_error changes specific to 1.3 introduced a buffer
6461 overrun in the (now legacy) log_printf function. Fixed.
6464 *) mod_digest didn't properly deal with proxy authentication. It
6465 also lacked a case-insensitive comparision of the "Digest"

6500 [Ben Reser <breser@regnow.com>] PR#1366
6502 *) The bputc() macro was not properly integrated with the chunking
6503 code; in many cases modules using bputc() could cause completely
6504 bogus chunked output. (Typically this will show up as problems
6505 with Internet Explorer 4.0 reading a page, but other browsers
6506 having no problem.) [Dean Gaudet]
6508 *) Create LARGE_WRITE_THRESHOLD define which determines how many
6509 bytes have to be supplied to bwrite() before it will consider
6510 doing a writev() to assemble multiple buffers in one system
6511 call. This is critical for modules such as mod_include,
6512 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
6513 strings in some cases. The result would be extra effort
6514 setting up writev(), and in many cases extra effort building
6515 chunks. The default is 31, it can be overriden at compile
6518 *) Move the gid switching code into the child so that log files
6519 and pid files are opened with the root gid.

6526 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
6527 so the functionality is available to applications other than the
6528 server itself (like the src/support tools). [Ken Coar]
6530 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
6531 the libap consolidation work. [Ken Coar]

6544 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"

6625 This turns out to be a bug in Winsock - select() doesn't always

6628 *) Directives owned by http_core can now use the new check_cmd_context()
6629 routine to ensure that they're not being used within a container
6630 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
6632 *) PORT: Recent changes made it necessary to add explicit prototype
6633 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
6635 *) It was necessary to distinguish between resources which are
6636 allocated in the parent, for cleanup in the parent, and resources
6637 which are allocated in each child, for cleanup in each child.
6638 A new pool was created which is passed to the module child_init
6639 and child_exit functions; modules are free to register per-child
6640 cleanups there. This fixes a bug with reliable piped logs.
6643 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
6644 unless it was also doing FancyIndexes, but it displayed the
6645 HeaderName file at the top under all circumstances. It now shows
6646 the ReadmeName file for simple indices, too, as it should.
6649 *) http_core was mmap()ing even in cases where it wasn't going to
6650 read the file. [Ben Hyde <bhyde@gensym.com>]
6652 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
6653 Now the rewriting engine (the heart of mod_rewrite) is organized more
6654 straight-forward, first time well documented and reduced to the really
6655 essential parts. All redundant cases were stripped off and processing now
6656 is the same for both per-server and per-directory context with only a
6657 minimum difference (the prefix stripping in per-dir context). As a
6658 side-effect some subtle restrictions and two recently discovered problems
6659 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
6660 context and restrictions on the substitution URL on redirects.
6661 Additionally some minor source cleanups were done.

6818 *) TestCompile was not passing $LIBS [Dean Gaudet]
6820 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6823 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6824 rudimentary memory debugger which can be used on live servers with
6825 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6826 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6827 and free() for each object. This is far more expensive and should
6828 only be used for testing with tools such as Electric Fence and
6829 Purify. See main/alloc.c for more details. [Dean Gaudet]
6831 *) Configure uses a sh trap and didn't set its exitcode properly.
6832 [Dean Gaudet] PR#1159
6834 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6835 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6836 From a given ip:port, regardless what the Host: header is, you can
6837 only reach the vhosts defined on that ip:port. The precedence of
6838 vhosts was reversed to match other precedences in the config --
6839 the earlier vhosts override the later vhosts. All vhost matching was
6840 moved into http_vhost.[ch]. [Dean Gaudet]
6842 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6843 be used for whatever reason is appropriate (i.e. format() warnings
6844 for printf style functions). Both are enabled only with
6845 gcc >= 2.7.x (so that we have fewer support issues with older
6846 versions). [Dean Gaudet]

6884 *) RedirectMatch was not properly escaping the result (PR#1155). Also
6885 "RedirectMatch /advertiser/(.*) $1" is now permitted.
6888 *) mod_include now uses symbolic names to check for request success
6889 and return HTTP errors, and correctly handles all types of
6890 redirections (previously it only did temporary redirect correctly).

6915 *) API: the short_score record has been split into two pieces, one which
6916 the parent writes on, and one which the child writes on. As part of
6917 this change the get_scoreboard_info() function was removed, and
6918 scoreboard_image was exported. This change fixes a race condition
6919 in file based scoreboard systems, and speeds up changes involving the
6920 scoreboard in earlier 1.3 development. [Dean Gaudet]
6922 *) API: New register_other_child() API (see http_main.h) which allows
6923 modules to register children with the parent for maintenance. It
6924 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
6926 *) API: New piped_log API (see http_log.h) which implements piped logs,
6927 and will use register_other_child to implement reliable piped logs
6928 when it is available. The reliable piped logs part can be disabled
6929 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
6930 logs is only available on Unix. [Dean Gaudet]
6932 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
6933 meets_conditions(). This allows conditional HTTP selection to be
6934 handled separately from the storing of the header fields, and provides
6935 the ability for CGIs to set their own ETags for conditional checking.
6936 [Ken Coar, Roy Fielding] PR#895
6938 *) Changes to mod_log_config to allow naming of format strings.
6939 Format nicknames are defined with "LogFormat fmt nickname", and can
6940 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
6943 *) New module, "mod_speling", which can help find files even when
6944 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
6946 *) API: New function child_terminate() triggers the child process to
6947 exit, while allowing the child finish what it needs to for the
6948 current request first.
6949 [Doug MacEachern, Alexei Kosut]
6951 *) Windows now defaults to using full status reports with mod_status.
6952 [Alexei Kosut] PR #1094
6954 *) *Really* disable all mod_rewrite operations if the engine is off.
6955 Some things (like RewriteMaps) were checked/performed even if they
6956 weren't supposed to be. [Ken Coar] PR #991
6958 *) Implement a new timer scheme which eliminates the need to call alarm() all
6959 the time. Instead a counter in the scoreboard for each child is used to
6960 show when the child has made forward progress. The parent samples this
6961 counter every scoreboard maintenance cycle, and issues SIGALRM if no
6962 progress has been made in the timeout period. This reduces the static
6963 request best-case syscall count to 22 from 29. This scheme is only
6964 used by systems with memory-based scoreboards. [Dean Gaudet]
6966 *) The proxy now properly handles CONNECT requests which are sent
6967 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
6969 *) A script called apachectl has been added to the support
6970 directory. This script allows you to do things such as
6971 "apachectl start" and "apachectl restart" from the command
6974 *) Modules and core routines are now put into libraries, which
6975 simplifies the link line tremendously (among other advantages).
6978 *) Some of the MD5 names defined in Apache have been renamed to have
6979 an `ap_' prefix to avoid conflicts with routines supplied by
6980 external libraries. [Ken Coar]
6982 *) Removal of mod_auth_msql.c from the distribution. There are many
6983 other options for databases today. Rather than offer one option,
6984 offer none at this time. mod_auth_msql and other SQL database
6985 authentication modules can be found at the Apache Module Registry.
6986 http://modules.apache.org/ It would be nice to offer a generic
6987 mod_auth_sql option in the near future.
6989 *) PORT: BeOS support added [Alexei Kosut]
6991 *) Configure no longer accepts the -make option, since it creates
6992 Makefile on the fly based on Makefile.tmpl and Configuration.
6994 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
6995 of forcibly killing off all its processes and exiting without
6996 cleaning up. [Alexei Kosut]
6998 *) API: A new field in the request_rec, r->mtime, has been added to
6999 avoid gratuitous parsing of date strings. It is intended to hold
7000 the last-modified date of the resource (if applicable). An
7001 update_mtime() routine has also been added to advance it if
7002 appropriate. [Roy Fielding, Ken Coar]
7004 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7005 deny access to the directory with a HTTP_FORBIDDEN. The previous
7006 behavior was to ignore the htaccess file if it could not be read.
7007 This change may make some setups with unreadable htaccess files
7008 stop working. [Marc Slemko] PR#817
7010 *) Add aplog_error() providing a mechanism to define levels of
7011 verbosity to the server error logging. This addition also provides
7012 the ability to log errors using syslogd. Error logging is configurable
7013 on a per-server basis using the LogLevel directive. Conversion
7014 of log_*() in progress. [Randy Terbush]
7016 *) Further enhance aplog_error() to not log filename, line number, and
7017 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7019 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7020 converted to long ones. Backslashes are converted to forward
7021 slashes. Case is converted to lower. Parts of URLs that do not
7022 correspond to files are left completely alone. [Ben Laurie]
7024 *) PORT: 2 new OSs added to the list of ports:
7025 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7026 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7028 *) Add the server version (SERVER_VERSION macro) to the "server
7029 configured and running" entry in the error_log. Also build an
7030 object file at link-time that contains the current time
7031 (SERVER_BUILT global const char[]), and include that in the
7034 *) Set r->headers_out when sending responses from the proxy.
7035 This fixes things such as the logging of headers sent from
7036 the proxy. [Marc Slemko] PR#659
7038 *) support/httpd_monitor is no longer distributed because the
7039 scoreboard should not be file based if at all possible. Use
7040 mod_status to see current server snapshot.
7042 *) (set_file_slot): New function, allowing auth directives to be
7043 independent of the server root, so the server documents can be
7044 moved to a different directory or machine more easily.
7045 [David J. MacKenzie]
7047 *) If no TransferLog is given explicitly, decline
7048 to log. This supports coexistence with other logging modules,
7049 such as the custom one that UUNET uses. [David J. MacKenzie]
7051 *) Check for titles in server-parsed HTML files.
7052 Ignore leading newlines and returns in titles. The old behavior
7053 of replacing a newline after <title> with a space causes the
7054 title to be misaligned in the listing. [David J. MacKenzie]
7056 *) Change mod_cern_meta to be configurable on a per-directory basis.
7057 [David J. MacKenzie]
7059 *) Add 'Include' directive to allow inclusion of configuration
7060 files within configuration files. [Randy Terbush]
7062 *) Proxy errors on connect() are logged to the error_log (nothing
7063 new); now they include the IP address and port that failed
7064 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7066 *) Various architectures now define USE_MMAP_FILES which causes
7067 the server to use mmap() for static files. There are two
7068 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7069 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7070 number of bytes written in one cycle from a single mmap()d object,
7071 default 32768). [Dean Gaudet]
7073 *) API: Added post_read_request API phase which is run right after reading
7074 the request from a client, or right after an internal redirect. It is
7075 useful for modules setting environment variables that depend only on
7076 the headers/contents of the request. It does not run during subrequests
7077 because subrequests inherit pretty much everything from the main
7078 request. [Dean Gaudet]
7080 *) Added mod_unique_id which is used to generate a unique identifier for
7081 each hit, available in the environment variable UNIQUE_ID.
7084 *) init_modules is now called after the error logs have been opened. This
7085 allows modules to emit information messages into the error logs.
7088 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7089 information for case where proxy module is not available. [Marc Slemko]
7091 *) PORT: Apache has need for mutexes to serialize its children around
7092 accept. In prior versions either fcntl file locking or flock file
7093 locking were used. The method is chosen by the definition of
7094 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7095 and FLOCK for flock(). New options have been added:
7096 - SYSVSEM to use System V style semaphores
7097 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7098 - USLOCK to use IRIX uslock
7099 Based on timing various techniques, the following changes were made
7101 - Linux 2.x uses flock instead of fcntl
7102 - Solaris 2.x uses pthreads
7103 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7104 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7105 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7106 Martijn Koster <m.koster@pobox.com>]
7108 *) PORT: The semantics of accept/select make it very desirable to use
7109 mutexes to serialize accept when multiple Listens are in use. But
7110 in the case where only a single socket is open it is sometimes
7111 redundant to serialize accept(). Not all unixes do a good job with
7112 potentially dozens of children blocked on accept() on the same
7113 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7114 the server will avoid serialization when listening on only one socket,
7115 and use serialization when listening on multiple sockets.
7116 [Dean Gaudet] PR#467
7118 *) Configure changes: TestLib replaced by TestCompile, which has
7119 some additional capability (such as doing a sanity check of
7120 the compiler and flags selected); the version of Solaris is now
7121 available via the #define value of SOLARIS2; IRIX n32bit libs
7122 now supported and selectable by new Configuration Rule: IRIXN32;
7123 We no longer default to -O2 optimization. [Jim Jagielski]
7125 *) Updated Configure: Configuration now uses AddModule to specify
7126 module source or binary file location, relative to src directory.
7127 Modules can be dropped into modules/extra, or in their own
7128 directory, and modules can come with a Makefile or Configure can
7129 create one. Modules can add compiler or library information to
7130 generated Makefiles. [Paul Sutton]
7132 *) Source core re-organisation: distributed modules are now in
7133 modules/standard. All other source code is in main. OS-specific
7134 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7136 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7139 *) Fix another long-standing bug in sub_req_lookup_file where it would
7140 happily skip past access checks on subdirectories looked up with
7141 relative paths. (It's used by mod_dir, mod_negotiation,
7142 and mod_include.) [Dean Gaudet]
7144 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7145 N is the number of <Directory> sections, and M is the number of
7146 components in the filename of an object.
7148 To achieve this optimization the following config changes were made:
7149 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7150 <Files>s, and <Location>s now treat a slash as a special
7151 character. For example "/home/*/public_html" previously would
7152 match "/home/a/andrew/public_html", now it only matches things
7153 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7154 - It's possible now to use [] wildcarding in <Directory>, <Files>
7156 - Regex <Directory>s are applied after all non-regex <Directory>s.
7160 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7161 and corrupted paths. [Dean Gaudet]
7163 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7164 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7165 be accessed now via backreferences $1..$9 in RewriteConds test-against
7166 strings in addition to RewriteRules subst string. Second the grouped
7167 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7168 via backreferences %1..%9 both in following RewriteCond test-against
7169 strings and RewriteRules subst string. This provides maximum flexibility
7170 through the use of backreferences.
7171 Additionally the rewriting engine was cleaned up by putting common
7172 code to the new expand_backrefs_inbuffer() function.
7173 [Ralf S. Engelschall]
7175 *) When merging the main server's <Directory> and <Location> sections into
7176 a vhost, put the main server's first and the vhost's second. Otherwise
7177 the vhost can't override the main server. [Dean Gaudet] PR#717
7179 *) The <Directory> code would merge and re-merge the same section after
7180 a match was found, possibly causing problems with some modules.
7183 *) ip-based vhosts are stored and queried using a hashing function, which
7184 has been shown to improve performance on servers with many ip-vhosts.
7185 Some other changes had to be made to accommodate this:
7186 - the * address for vhosts now behaves like _default_
7187 - the matching process now is:
7188 - match an ip-vhost directly via hash (possibly matches main
7190 - if that fails, just pretend it matched the main server
7191 - if so far only the main server has been matched, perform
7192 name-based lookups (ServerName, ServerAlias, ServerPath)
7193 *only on name-based vhosts*
7194 - if they fail, look for _default_ vhosts
7195 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7197 *) dbmmanage overhaul:
7198 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7199 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7200 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7201 - provide better seed for rand
7202 - prompt for password as per getpass(3) (turn off echo, read from
7204 - use "newstyle" crypt based on $Config{osname} ($^O)
7205 - will not add a user if already in database, use new `update' command
7207 - added `check' command to check a users' password
7208 - added `import' command to convert existing password text-files or
7209 dbm files exported with `view'
7210 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7213 *) Added psocket() which is a pool form of socket(), various places within
7214 the proxy weren't properly blocking alarms while registering the cleanup
7215 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7216 was a bug where the client socket was being close()d twice due a still
7217 registered cleanup. [Dean Gaudet]
7219 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7222 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7223 [Jason Venner <jason@idiom.com>] PR#667
7225 *) Enable ``=""'' for RewriteCond directives to match against
7226 the empty string. This is the preferred way instead of ``^$''.
7227 [Ralf S. Engelschall]
7229 *) Fixed an infinite loop in mod_imap for references above the server root
7230 [Dean Gaudet] PR#748
7232 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7233 SendBufferSize, so that the TCP window can be set appropriately
7234 for LFNs. [Phillip A. Prindeville]
7236 *) mod_browser has been replaced by the more general mod_setenvif
7237 (courtesy of Paul Sutton). BrowserMatch* directives are still
7238 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7239 UnSetEnvIfZero directives. [Ken Coar]
7241 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7242 order for remote_host to be set (for logging, or for the env var
7243 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7246 *) mod_access overhaul:
7247 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7248 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7249 - Critical path was sped up by pre-computing a few things at config time.
7250 - The undocumented syntax "allow user-agents" was removed,
7251 the replacement is "allow from env=foobar" combined with mod_browser.
7252 - When used with hostnames it now forces a double-reverse lookup
7253 no matter what the directory settings are. This double-reverse
7254 doesn't affect any of the other routines that use the remote
7255 hostname. In particular it's still passed to CGIs and the log
7256 without the double-reverse check. Related PR#860.
7259 *) When a large bwrite() occurs (larger than the internal buffer size),
7260 while there is already something in the buffer, apache will combine
7261 the large write and the buffer into a single writev(). (This is
7262 in anticipation of using mmap() for reading files.)
7265 *) In obscure cases where a partial socket write occurred while chunking,
7266 Apache would omit the chunk header/footer on the next block. Cleaned
7267 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7268 a bug where a long pause in DNS lookups could cause the last packet
7269 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7271 *) API: Added child_exit function to module structure. This is called
7272 once per "heavy-weight process" just before a server child exit()'s
7273 e.g. when max_requests_per_child is reached, etc.
7274 [Doug MacEachern, Dean Gaudet]
7276 *) mod_include cleanup showed that handle_else was being used to handle
7277 endif. It didn't cause problems, but it was cleaned up too.
7280 *) mod_cern_meta would attempt to find meta files for the directory itself
7281 in some cases, but not in others. It now avoids it in all cases.
7284 *) mod_mime_magic would core dump if there was a decompression error.
7285 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7287 *) PORT: some variants of DGUX require -lsocket -lnsl
7288 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7290 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7291 by the various fields (name, size, et cetera), either in ascending
7292 or descending order. Just click on the column header. [Ken Coar]
7294 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7295 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7296 the relatively safe direction. [Dean Gaudet] PR#344
7298 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7299 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7301 *) child_main avoids an unneeded call to select() when there is only one
7302 listening socket. [Dean Gaudet]
7304 *) In the event that the server is starved for idle servers it will
7305 spawn 1, then 2, then 4, ..., then 32 servers each second,
7306 doubling each second. It'll also give a warning in the errorlog
7307 since the most common reason for this is a poor StartServers
7308 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7309 the maximum. [Dean Gaudet]
7311 *) Apache now provides an effectively unbuffered connection for
7312 CGI scripts. This means that data will be sent to the client
7313 as soon as the CGI pauses or stops output; previously, Apache would
7314 buffer the output up to a fixed buffer size before sending, which
7315 could result in the user viewing an empty page until the CGI finished
7316 or output a complete buffer. It is no longer necessary to use an
7317 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7318 in a language that by default does buffering (e.g. perl) this
7319 shouldn't have a detrimental effect on performance.
7321 "nph-" CGIs, which formerly provided a direct socket to the client
7322 without any server post-processing, were not fully compatible with
7323 HTTP/1.1 or SSL support. As such they would have had to implement
7324 the transport details, such as encryption or chunking, in order
7325 to work properly in certain situations. Now, the only difference
7326 between nph and non-nph scripts is "non-parsed headers".

7330 bread() will return whatever remained in the buffer prior to the
7331 switch. [Dean Gaudet]
7333 Changes with Apache 1.3a1
7335 *) Added another Configure helper script: TestLib. It determines
7336 if a specified library exists. [Jim Jagielski]
7338 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
7339 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
7342 *) PORT: Some architectures use size_t for various lengths in network
7343 functions such as accept(), and getsockname(). The definition
7344 NET_SIZE_T is used to control this. [Dean Gaudet]
7346 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
7347 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
7348 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
7350 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
7351 [Igor N Kovalenko <infoh@mail.wplus.net>]
7353 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7354 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7355 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

7358 *) API: Correct child_init() slot declaration from int to void, to
7359 match the init() declaration. Update mod_example to use the new

7384 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
7385 header to the remote host in the proxy. [Sameer Parekh and
7388 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
7389 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
7390 URLs, fixed rewritelog(), fixed forced response code handling on
7391 redirects from within .htaccess files, disabled pipe locking under
7392 braindead SunOS 4.1.x, allow env variables to be set even on rules with
7393 no substitution, bugfixed situations where HostnameLookups is off, made
7394 mod_rewrite more thread-safe for NT port and fixed problem when creating
7395 an empty query string via "xxx?".
7396 This update also removes the copyright of Ralf S. Engelschall,
7397 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
7398 exclusively copyrighted by the Apache Group now. This happened because
7399 the author now has gifted mod_rewrite exclusively to the Apache Group and
7400 no longer maintains an external version.
7401 [Ralf S. Engelschall]

7424 [Ken Coar, Roy Fielding, Andrey A. Chernov]
7426 *) WIN32: Modules can now be dynamically loaded DLLs using the
7427 LoadModule/LoadFile directives. Note that module DLLs must be
7428 compiled with the multithreaded DLL version of the runtime library.
7429 [Alexei Kosut and Ben Laurie]
7431 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
7432 This allows the admin to completely remove automatic indexing
7433 from the server, while still supporting the basic functions of
7434 trailing-slash redirects and DirectoryIndex files. Note that if
7435 you're carrying over an old Configuration file and you use directory
7436 indexing then you'll want to add:
7438 Module autoindex_module mod_autoindex.o
7440 before mod_dir in your Configuration. [Dean Gaudet]
7442 *) popendir/pclosedir created to properly protect directory scanning.
7443 [Dean Gaudet] PR#525
7445 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
7446 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
7447 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
7450 *) The AccessFileName directive can now take more than one filename.
7451 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7453 *) The new mod_mime_magic can be used to "magically" determine the type
7454 of a file if the extension is unknown. Based on the unix file(1)
7455 command. [Ian Kluft <ikluft@cisco.com>]
7457 *) We now determine and display the time spent processing a
7458 request if desired. [Jim Jagielski]
7460 *) mod_status: PID field of "dead" child slots no longer displays
7461 main httpd process's PID. [Jim Jagielski]
7463 *) Makefile.nt added - to build all the bits from the command line:
7464 nmake -f Makefile.nt
7465 Doesn't yet work properly. [Ben Laurie]
7467 *) Default text of 404 error is now "Not Found" rather than the
7468 potentially misleading "File Not Found". [Ken Coar]
7470 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
7471 for the net if we require people that actually need this data to
7472 enable it. [Linus Torvalds]
7474 *) directory_walk() is an expensive function, keep a little more state to
7475 avoid needless string counting. Add two new functions make_dirstr_parent
7476 and make_dirstr_prefix which replace all existing uses of make_dirstr.
7477 The new functions are a little less general than make_dirstr, but
7478 work more efficiently (less memory, less string counting).
7481 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
7482 to LDFLAGS) to avoid complications with lex rules in make files.
7483 [Dean Gaudet] PR#372
7485 *) run_method optimized to avoid needless scanning over NULLs in the
7486 module list. [Dean Gaudet]
7488 *) Revamp of (unix) scoreboard management code such that it avoids
7489 unnecessary traversals of the scoreboard on each hit. This is
7490 particularly important for high volume sites with a large
7491 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
7492 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
7493 httpd.h. [Dean Gaudet]
7495 *) In configurations using multiple Listen statements it was possible for
7496 busy sockets to starve other sockets of service. [Dean Gaudet]
7498 *) Added hook so standalone_main can be replaced at compile time
7499 (define STANDALONE_MAIN)
7502 *) Lowest-level read/write functions in buff.c will be replaced with
7503 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
7504 compile time. The default sfio discipline will behave as apache
7505 would without sfio compiled in.
7508 *) Enhance UserDir directive (mod_userdir) to accept a list of
7509 usernames for the 'disable' keyword, and add 'enable user...' to
7510 selectively *en*able userdirs if they're globally disabled.
7513 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
7514 will work with Netscape dbm files. (dbmmanage will probably not
7515 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
7517 *) Add a ListenBacklog directive to control the backlog parameter
7518 passed to listen(). Also change the default to 511 from 512.
7521 *) API: A new handler response DONE which informs apache that the
7522 request has been handled and it can finish off quickly, similar to
7523 how it handles errors. [Rob Hartill]
7525 *) Turn off chunked encoding after sending terminating chunk/footer
7526 so that we can't do it twice by accident. [Roy Fielding]
7528 *) mod_expire also issues Cache-Control: max-age headers.
7531 *) API: Added kill_only_once option for free_proc_chain so that it won't
7532 aggressively try to kill off specific children. For fastcgi.
7533 [Stanley Gambarin <gambarin@OpenMarket.com>]
7535 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
7537 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
7538 When used together, these cause mod_dir to emit HEIGHT and WIDTH
7539 attributes in the FancyIndexing IMG tags. [Ken Coar]
7541 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
7543 *) PORT: Added Windows NT support
7544 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
7546 Changes with Apache 1.2.6
7548 *) mod_include when using XBitHack Full would send ETags in addition to
7549 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
7550 [Dean Gaudet] PR#1133
7552 *) SECURITY: When a client connects to a particular port/addr, and
7553 gives a Host: header ensure that the virtual host requested can
7554 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
7556 *) Support virtual hosts with wildcard port and/or multiple ports
7557 properly. [Ed Korthof <ed@organic.com>]
7559 *) Fixed some case-sensitivity issues according to RFC2068.
7562 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
7563 and mod_include.c. [Dean Gaudet]
7565 *) Variable 'cwd' was being used pointlessly before being set.
7568 *) SIGURG doesn't exist on all platforms.
7569 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7571 *) When an error occurs during a POST, or other operation with a
7572 request body, the body has to be read from the net before allowing
7573 a keepalive session to continue. [Roy Fielding] PR#1399
7575 *) When an error occurs in fcntl() locking suggest the user look up
7576 the docs for LockFile. [Dean Gaudet]
7578 *) table_set() and table_unset() did not deal correctly with
7579 multiple occurrences of the same key. [Stephen Scheck
7580 <sscheck@infonex.net>, Ben Laurie] PR#1604
7582 *) send_fd_length() did not calculate total_bytes_sent properly in error
7583 cases. [Ben Reser <breser@regnow.com>] PR#1366
7585 *) r->connection->user was allocated in the wrong pool causing corruption
7586 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
7588 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7589 Also removed the auto-generated link to www.apache.org that was the
7590 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7592 *) Multiple "close" tokens may have been set in the "Connection"
7593 header, not an error, but a waste.
7594 [Ronald.Tschalaer@psi.ch] PR#1683
7596 *) "basic" and "digest" auth tokens should be tested case-insensitive.
7597 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
7599 *) It appears the "257th byte" bug (see
7600 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7601 at the 256th byte as well. Fixed. [Dean Gaudet]
7603 *) mod_rewrite would not handle %3f properly in some situations.
7606 *) Apache could generate improperly chunked HTTP/1.1 responses when
7607 the bputc() or rputc() functions were used by modules (such as
7608 mod_include). [Dean Gaudet]
7610 *) #ifdef wrap a few #defines in httpd.h to make life easier on
7611 some ports. [Ralf Engelschall]
7613 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
7615 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
7617 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
7619 Changes with Apache 1.2.5
7621 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7622 only an issue on systems without a MAXDNAME define or where
7623 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7625 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
7628 *) Fix core dump in the ftp proxy when reading incorrectly formatted
7629 directory listings. [Marc Slemko]
7631 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
7634 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7635 is used to read various types of files such as htaccess and
7636 htpasswd files. [Marc Slemko]
7638 *) SECURITY: Ensure that the buffer returned by ht_time is always
7639 properly null terminated. [Marc Slemko]
7641 *) SECURITY: General mod_include cleanup, including fixing several
7642 possible buffer overflows and a possible infinite loop. This cleanup
7643 was done against 1.3 code and then backported to 1.2, the result
7644 is a large difference (due to indentation cleanup in 1.3 code).
7645 Users interested in seeing a smaller set of relevant differences
7646 should consider comparing against src/modules/standard/mod_include.c
7647 from the 1.3b3 release. Non-indentation changes to mod_include
7648 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
7650 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7651 including fixing a possible buffer overflow. This cleanup also
7652 was done with 1.3 code as a basis, see the the previous note
7653 about mod_include. [Dean Gaudet]
7655 *) SECURITY: If a htaccess file can not be read due to bad
7656 permissions, deny access to the directory with a HTTP_FORBIDDEN.
7657 The previous behavior was to ignore the htaccess file if it could not
7658 be read. This change may make some setups with unreadable
7659 htaccess files stop working. PR#817 [Marc Slemko]
7661 *) SECURITY: no2slash() was O(n^2) in the length of the input.
7662 Make it O(n). This inefficiency could be used to mount a denial
7663 of service attack against the Apache server. Thanks to
7664 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
7667 *) mod_include used uninitialized data for some uses of && and ||.
7668 [Brian Slesinsky <bslesins@wired.com>] PR#1139
7670 *) mod_imap should decline all non-GET methods.
7671 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
7673 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7675 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7676 r->filename. Since those two are meant to be in sync with each other
7677 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7679 *) mod_include did not properly handle all possible redirects from sub-
7680 requests. [Ken Coar]
7682 *) Inetd mode (which is buggy) uses timeouts without having setup the
7683 jmpbuffer. [Dean Gaudet] PR#1064
7685 *) Work around problem under Linux where a child will start looping
7686 reporting a select error over and over.
7687 [Rick Franchuk <rickf@transpect.net>] PR#1107
7689 Changes with Apache 1.2.4
7691 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7692 always making requests with the full-URI instead of just the URI path.
7693 [Marc Slemko, Roy Fielding]
7695 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7696 on this platform. [Marc Slemko]
7698 Changes with Apache 1.2.3
7700 *) The request to a remote proxy was mangled if it was generated as the
7701 result of a ProxyPass directive. URL schemes other than http:// were not
7702 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
7703 PR#812 [Lars Eilebrecht]
7705 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7706 information for case where proxy module is not available. [Marc Slemko]
7708 *) Force proxy to always respond as HTTP/1.0, which it was failing to
7709 do for errors and cached responses. [Roy Fielding]
7711 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
7713 Changes with Apache 1.2.2 [not released]
7715 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7716 happily skip past access checks on subdirectories looked up with relative
7717 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7720 *) Add lockfile name to error message printed out when
7721 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7724 *) Enhanced the chunking and error handling inside the buffer functions.
7725 [Dean Gaudet, Roy Fielding]
7727 *) When merging the main server's <Directory> and <Location> sections into
7728 a vhost, put the main server's first and the vhost's second. Otherwise
7729 the vhost can't override the main server. [Dean Gaudet] PR#717
7731 *) The <Directory> code would merge and re-merge the same section after
7732 a match was found, possibly causing problems with some modules.
7735 *) Fixed an infinite loop in mod_imap for references above the server root.
7736 [Dean Gaudet] PR#748
7738 *) mod_include cleanup showed that handle_else was being used to handle
7739 endif. It didn't cause problems, but it was cleaned up too.
7742 *) Last official synchronization of mod_rewrite with author version (because
7743 mod_rewrite is now directly developed by the author at the Apache Group):
7744 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7745 minus WIN32/NT stuff, but plus copyright removement.
7747 - workaround for detecting infinite rewriting loops
7748 - fixed setting of env vars when "-" is used as subst string
7749 - fixed forced response code on redirects (PR#777)
7750 - fixed cases where r->args is ""
7751 - kludge to disable locking on pipes under braindead SunOS
7752 - fix for rewritelog in cases where remote hostname is unknown
7753 - fixed totally damaged request_rec walk-back loop
7754 o remove static from local data and add static to global ones.
7755 o replaced ugly proxy finding stuff by simple
7756 find_linked_module("mod_proxy") call.
7757 o added missing negation char on rewritelog()
7758 o fixed a few comment typos
7759 [Ralf S. Engelschall]
7761 *) Anonymous_LogEmail was logging on each subrequest.
7762 [Dean Gaudet] PR#421, PR#868
7764 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7765 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7766 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7767 Additionally mod_browser now triggers during translate_name to workaround
7768 a deficiency in the header_parse phase.
7769 [Dean Gaudet] PR#875
7771 *) get_client_block() returns wrong length if policy is
7772 REQUEST_CHUNKED_DECHUNK.

7775 *) Properly treat <files> container like other containers in mod_info.
7776 [Marc Slemko] PR#848
7778 *) The proxy didn't treat the "Host:" keyword of the host header as case-
7779 insensitive. The proxy would corrupt the first line of a response from
7780 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
7782 *) mod_include would log some bogus values occasionally.
7783 [Skip Montanaro <skip@calendar.com>, Marc Slemko] PR#797
7785 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
7786 under Solaris 2.x (up through 2.5.1). It has been fixed.
7787 [Dean Gaudet] PR#832
7789 *) API: In HTTP/1.1, whether or not a request message contains a body
7790 is independent of the request method and based solely on the presence
7791 of a Content-Length or Transfer-Encoding. Therefore, our default
7792 handlers need to be prepared to read a body even if they don't know
7793 what to do with it; otherwise, the body would be mistaken for the
7794 next request on a persistent connection. discard_request_body()
7795 has been added to take care of that. [Roy Fielding] PR#378
7797 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
7798 release version number, such that it always increases along the
7799 same lines as our source code branching. [Roy Fielding]
7801 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
7803 Changes with Apache 1.2.1
7805 *) SECURITY: Don't serve file system objects unless they are plain files,
7806 symlinks, or directories. This prevents local users from using pipes
7807 or named sockets to invoke programs for an extremely crude form of

7811 could contain "../" allowing a local user to "publish" any file on
7812 the system. No slashes are allowed now. [Dean Gaudet]
7814 *) SECURITY: It was possible to violate the symlink Options using mod_dir
7815 (headers, readmes, titles), mod_negotiation (type maps), or
7816 mod_cern_meta (meta files). [Dean Gaudet]
7818 *) SECURITY: Apache will refuse to run as "User root" unless
7819 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7821 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7822 if it contained a .htaccess disallowing symlinks. This is contrary
7823 to the rule that symlink permissions are tested with the symlink
7824 options of the parent directory. [Dean Gaudet] PR#353
7826 *) CONFIG: The LockFile directive can be used to place the serializing
7827 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
7828 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
7831 *) Request processing now retains state of whether or not the request
7832 body has been read, so that internal redirects and subrequests will
7833 not try to read it twice (and block). [Roy Fielding]
7835 *) Add a placeholder in modules/Makefile to avoid errors with certain
7836 makes. [Marc Slemko]
7838 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

7841 *) mod_include was not properly changing the current directory.
7842 [Marc Slemko] PR#742
7844 *) Attempt to work around problems with third party libraries that do not
7845 handle high numbered descriptors (examples include bind, and
7846 solaris libc). On all systems apache attempts to keep all permanent
7847 descriptors above 15 (called the low slack line). Solaris users
7848 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7849 which keeps all non-FILE * descriptors above 255. On all systems
7850 this should make supporting large numbers of vhosts with many open
7851 log files more feasible. If this causes trouble please report it,
7852 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7853 [Dean Gaudet] various PRs
7855 *) Related to the last entry, network sockets are now opened before
7856 log files are opened. The only known case where this can cause
7857 problems is under Solaris with many virtualhosts and many Listen
7858 directives. But using -DHIGH_SLACK_LINE=256 described above will
7859 work around this problem. [Dean Gaudet]
7861 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
7864 *) Improved unix error response logging. [Marc Slemko]
7866 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
7867 QSA=query_string_append. Also fixed a nasty bug in per-dir context:

7914 reading from one buffer and writing to another, at least until it has
7915 a custom timeout handler. [Roy Fielding and Petr Lampa]

7968 *) Restored the semantics of headers_out (headers sent only with 200..299
7969 and 304 responses) and err_headers_out (headers sent with all responses).
7970 Avoid the overhead of copying tables if err_headers_out is empty
7971 (the usual case). [Roy Fielding]
7973 *) Fixed a couple places where a check for the default Content-Type was
7974 not properly checking both the value configured by the DefaultType
7975 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
7976 of DEFAULT_TYPE to match the documented default (text/plain).
7977 [Dean Gaudet] PR#506
7979 *) Escape the HTML-sensitive characters in the Request-URI that is
7980 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
7982 *) Properly initialize the flock structures used by the mutex locking
7983 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
7986 *) The method for determining PATH_INFO has been restored to the pre-1.2b
7987 (and NCSA httpd) definition wherein it was the extra path info beyond
7988 the CGI script filename. The environment variable FILEPATH_INFO has
7989 been removed, and instead we supply the original REQUEST_URI to any
7990 script that wants to be Apache-specific and needs the real URI path.
7991 This solves a problem with existing scripts that use extra path info
7992 in the ScriptAlias directive to pass options to the CGI script.
7995 *) The _default_ change in 1.2b10 will change the behaviour on configs
7996 that use multiple Listen statements for listening on multiple ports.
7997 But that change is necessary to make _default_ consistent with other
7998 forms of <VirtualHost>. It requires such configs to be modified
7999 to use <VirtualHost _default_:*>. The documentation has been
8000 updated. [Dean Gaudet] PR#530
8002 *) If an ErrorDocument CGI script is used to respond to an error
8003 generated by another CGI script which has already read the message
8004 body of the request, the server would block trying to read the
8005 message body again. [Rob Hartill]
8007 *) signal() replacement conflicted with a define on QNX (and potentially
8008 other platforms). Fixed. [Ben Laurie] PR#512
8010 Changes with Apache 1.2b10
8012 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
8013 to be configured via -D in Configuration. [Dean Gaudet] PR#449
8015 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
8017 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
8019 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
8020 config, in case the hostent struct returned is trash.
8021 [Chuck Murcko] PR #491
8023 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
8024 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
8026 Changes with Apache 1.2b9 [never announced]
8028 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8029 changes and in anticipation of 1.2 final release. [Roy Fielding]
8031 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8032 the connection (e.g., when user presses Stop). Apache will now stop
8033 trying to send a message body immediately after an error from write.
8034 [Roy Fielding and Nathan Kurz] PR#335
8036 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8037 than mod_alias, and mod_alias has higher priority than mod_proxy;
8038 rearranged other modules to enhance understanding of their purpose
8039 and relative order (and maybe even reduce some overhead).
8040 [Roy Fielding and Sameer Parekh]
8042 *) Fix graceful restart. Eliminate many signal-related race
8043 conditions in both forms of restart, and in SIGTERM. See
8044 htdocs/manual/stopping.html for details on stopping and
8045 restarting the parent. [Dean Gaudet]
8047 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8048 memory allocator to avoid a behaviour that required extra blocks to
8049 be allocated. [Dean Gaudet]
8051 *) Allow suexec to access files relative to current directory but not
8052 above. (Excluding leading / or any .. directory.) [Ken Coar]
8055 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8056 PR#367, 368, 354, 453
8058 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8059 while obtaining the /~user and save the username in a separate data
8060 area so that it won't be overwritten by the call to getgrgid(), and
8061 fix some misuse of the pool string allocation functions. Also fixes
8062 a general problem with parsing URL query info into args for CGI scripts.
8063 [Roy Fielding] PR#339, 367, 354, 453
8065 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
8067 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
8069 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
8070 AuthDBAuthoritative. [Marc Slemko] PR#420
8072 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8074 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8075 object that can't be PUT, or FOOBAR for some method FOOBAR that
8076 apache doesn't know about at all). Log 404s that occur in mod_include.
8077 [Paul Sutton, John Van Essen]
8079 *) If a soft timeout (or lingerout) occurs while trying to flush a
8080 buffer or write inside buff.c or fread'ing from a CGI's output,
8081 then the timeout would be ignored. [Roy Fielding] PR#373
8083 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8084 parsing of headers. If the terminating empty-line CRLF occurs starting
8085 at the 256th or 257th byte of output, then Navigator will think a normal
8086 image is invalid. We are guessing that this is because their initial
8087 read of a new request uses a 256 byte buffer. We check the bytes written
8088 so far and, if we are about to tickle the bug, we instead insert a
8089 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8091 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8092 of an external redirection. [Roy Fielding and Paul Sutton]
8094 *) Configure would create a broken Makefile if the configuration file
8095 contained a commented-out Rule. [Roy Fielding]
8097 *) Promote per_dir_config and subprocess_env from the subrequest to the
8098 main request in mod_negotiation. In particular this fixes a bug
8099 where <Files> sections wouldn't properly apply to negotiated content.
8102 *) Fix a potential deadlock in mod_cgi script_err handling.
8103 [Ralf S. Engelschall]
8105 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8108 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8109 .htaccess files because the RewriteBase was not replaced correctly.
8110 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8111 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8113 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8114 1.x the settings are those of pre-1.2b8. For 2.x we include
8115 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8116 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8117 [Dean Gaudet] PR#336, PR#340
8119 *) Redirect did not preserve ?query_strings when present in the client's
8120 request. [Dean Gaudet]
8122 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
8124 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8126 *) Add UnixWare compile/install instructions. [Chuck Murcko]
8128 *) Add mod_example (illustration of API techniques). [Ken Coar]
8130 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8132 *) Improve handling of directories when filenames have spaces in them.
8135 *) For hosts with multiple IP addresses, try all additional addresses if
8136 necessary to get a connect. Fail only if hostent address list is
8137 exhausted. [Chuck Murcko]
8139 *) More signed/unsigned port fixes. [Dean Gaudet]
8141 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8144 Changes with Apache 1.2b8
8146 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8147 to it. [Marc Slemko]
8149 *) The addition of <Location> and <File> directives made the
8150 sub_req_lookup_simple() function bogus, so we now handle
8151 the special cases directly. [Dean Gaudet]
8153 *) We now try to log where the server is dumping core when a fatal
8154 signal is received. [Ken Coar]
8156 *) Improved lingering_close by adding a special timeout, removing the
8157 spurious log messages, removing the nonblocking settings (they
8158 are not needed with the better timeout), and adding commentary
8159 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8160 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8162 *) Send error messages about setsockopt failures to the server error
8163 log instead of stderr. [Roy Fielding]
8165 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8167 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8168 processing a subrequest, allocate memory from r->main->pool instead
8169 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8170 in the middle of an SSI request. [Dean Gaudet] PR #122
8172 *) Fixed status of response when POST is received for a nonexistent URL
8173 (was sending 405, now 404) and when any method is sent with a
8174 full-URI that doesn't match the server and the server is not acting
8175 as a proxy (was sending 501, now 403). [Roy Fielding]
8177 *) Host port changed to unsigned short. [Ken Coar] PR #276
8179 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8181 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8183 *) Report extra info from errno with many errors that cause httpd to exit.
8184 spawn_child, popenf, and pclosef now have valid errno returns in the
8185 event of an error. Correct problems where errno was stomped on
8186 before being reported. [Dean Gaudet]
8188 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8189 never called, and thus the filesystem would remain full indefinitely.
8190 We now also remove incomplete cache files left if the origin server
8191 didn't send a Content-Length header and either the client has aborted
8192 transfer or bwrite() to client has failed. [Petr Lampa]
8194 *) Fixed the handling of module and script-added header fields.
8195 Improved the interface for sending header fields and reduced
8196 the duplication of code between sending okay responses and errors.
8197 We now always send both headers_out and err_headers_out, and
8198 ensure that the server-reserved fields are not being overridden,
8199 while not overriding those that are not reserved. [Roy Fielding]
8201 *) Moved transparent content negotiation fields to err_headers_out
8202 to reflect above changes. [Petr Lampa]
8204 *) Fixed the determination of whether or not we should make the
8205 connection persistent for all of the cases where some other part
8206 of the server has already indicated that we should not. Also
8207 improved the ordering of the test so that chunked encoding will
8208 be set whenever it is desired instead of only when KeepAlive
8209 is enabled. Added persistent connection capability for most error
8210 responses (those that do not indicate a bad input stream) when
8211 accessed by an HTTP/1.1 client. [Roy Fielding]
8213 *) Added missing timeouts for sending header fields, error responses,
8214 and the last chunk of chunked encoding, each of which could have
8215 resulted in a process being stuck in write forever. Using soft_timeout
8216 requires that the sender check for an aborted connection rather than
8217 continuing after an EINTR. Timeouts that used to be initiated before
8218 send_http_header (and never killed) are now initiated only within or
8219 around the routines that actually do the sending, and not allowed to
8220 propagate above the caller. [Roy Fielding]
8222 *) mod_auth_anon required an @ or a . in the email address, not both.
8225 *) per_dir_defaults weren't set correctly until directory_walk for
8226 name-based vhosts. This fixes an obscure bug with the wrong config
8227 info being used for vhosts that share the same ip as the server.
8230 *) Improved generation of modules/Makefile to be more generic for
8231 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8233 *) Generate makefile dependency for Configuration based on the actual
8234 name given when running the Configure process. [Dean Gaudet]
8236 *) Fixed problem with vhost error log not being set prior to
8237 initializing virtual hosts. [Dean Gaudet]
8239 *) Fixed infinite loop when a trailing slash is included after a type map
8240 file URL (extra path info). [Petr Lampa]
8242 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8244 *) Add documentation for DNS issues (reliability and security), and try
8245 to explain the virtual host matching process. [Dean Gaudet]
8247 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8248 fails while parsing the configuration file. [Dean Gaudet]
8250 *) Improved calls to setsockopt. [Roy Fielding]
8252 *) Negotiation changes: Don't output empty content-type in variant list;
8253 Output charset in variant list; Return sooner from handle_multi() if
8254 no variants found; Add handling of '*' wildcard in Accept-Charset.
8255 [Petr Lampa and Paul Sutton]
8257 *) Fixed overlaying of request/sub-request notes and headers in
8258 mod_negotiation. [Dean Gaudet]
8260 *) If two variants' charset quality are equal and one is the default
8261 charset (iso-8859-1), then prefer the variant that was specifically
8262 listed in Accept-Charset instead of the default. [Petr Lampa]
8264 *) Memory allocation problem in push_array() -- it would corrupt memory
8265 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8267 *) invoke_handler() doesn't handle mime arguments in content-type
8270 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8273 *) Fixed problem with ErrorDocument not working for virtual hosts
8274 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8276 *) Log an error message if we get a request header that is too long,
8277 since it may indicate a buffer overflow attack. [Marc Slemko]
8279 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8280 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8281 [Ken Coar] PR #146, #187
8283 *) Added table entry placeholder for new header_parser callback
8284 in all of the distributed modules. [Ken Coar] PR #191
8286 *) Allow for cgi files without the .EXE extension on them under OS/2.
8287 [Garey Smiley] PR #59
8289 *) Fixed error message when resource is not found and URL contains
8290 path info. [Petr Lampa and Dean Gaudet] PR #40
8292 *) Fixed user and server confusion over what should be a virtual host
8293 and what is the main server, resulting in access to something
8294 other than the name defined in the virtualhost directive (but
8295 with the same IP address) failing. [Dean Gaudet]
8297 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8298 AIX; improves the redirection stuff to enable the users to generally
8299 redirect to http, https, gopher and ftp; added TIME variable for
8300 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8301 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8302 can be used in conjunction with %{TIME} or other variables to create
8303 time-dependent rewriting rules. [Ralf S. Engelschall]
8305 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8306 Module authors may need to adjust their code for proper cleanup to take
8307 place (that is, call note_cleanups_for_fd()). This change fixes problems
8308 with file descriptors being erroneously closed when the proxy module was
8309 in use. [Ben Laurie]
8311 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8312 initgroups() to hose the group information needed for later
8313 comparisons. [Randy Terbush]
8315 *) Remove unnecessary call to va_end() in create_argv() which
8316 caused a SEGV on some systems.
8318 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8321 *) Clear memory allocated for listeners. [Randy Terbush]
8323 *) Improved handling of IP address as a virtualhost address and
8324 introduced "_default_" as a synonym for the default vhost config.

8327 Changes with Apache 1.2b7
8329 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
8331 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
8333 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
8334 - replace protocol response numbers with symbols
8335 - save variant-list into main request notes
8336 - free allocated memory from subrequests
8337 - merge notes, headers_out and err_headers_out
8339 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
8340 "HTTP/#.# ###*" to be more lenient about what we accept.
8343 *) more proxy FTP bug fixes:
8344 - Changed send_dir() to remove user/passwd from displayed URL.
8345 - Changed login error messages to be more descriptive.
8346 - remove setting of SO_DEBUG socket option
8347 - Make ftp_getrc() more lenient about multiline responses,
8348 specifically, 230 responses which don't have continuation 230-
8349 on each line). These seem to be all NT FTP servers, and while
8350 perhaps questionable, they appear to be legal by RFC 959.
8351 - Add missing kill_timeout() after transfer to user completes.
8354 *) Fixed problem where a busy server could hang when restarting
8355 after being sent a SIGHUP due to child processes not exiting.
8358 *) Modify mod_include escaping so a '\' only signifies an escaped
8359 character if the next character is one that needs
8360 escaping. [Ben Laurie]
8362 *) Eliminated possible infinite loop in mod_imap when relative URLs are
8363 used with a 'base' directive that does not have a '/' in it.
8364 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
8366 *) Reduced the default timeout from 1200 seconds to 300, and the
8367 one in the sample configfile from 400 to 300. [Marc Slemko]
8369 *) Stop vbprintf from crashing if given a NULL string pointer;
8370 print (null) instead. [Ken Coar]
8372 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
8373 [Marc Slemko and Roy Fielding]
8375 *) Fixed problem with mod_cgi-generated internal redirects trying to
8376 read the request message-body twice. [Archie Cobbs and Roy Fielding]
8378 *) Reduced timeout on lingering close, removed possibility of a blocked
8379 read causing the child to hang, and stopped logging of errors if
8380 the socket is not connected (reset by client). [Roy Fielding]
8382 *) Rearranged main child loop to remove duplication of code in
8383 select/accept and keep-alive requests, fixed several bugs regarding
8384 checking scoreboard_image for exit indication and failure to
8385 account for all success conditions and trap all error conditions,
8386 prevented multiple flushes before closing the socket; close the entire
8387 socket buffer instead of just one descriptor, prevent logging of
8388 EPROTO and ECONNABORTED on platforms where supported, and generally
8389 improved readability. [Roy Fielding]
8391 *) Extensive performance improvements. Cleaned up inefficient use of
8392 auto initializers, multiple is_matchexp calls on a static string,
8393 and excessive merging of response_code_strings. [Dean Gaudet]
8395 *) Added double-buffering to mod_include to improve performance on
8396 server-side includes. [Marc Slemko]
8398 *) Several fixes for suexec wrapper. [Randy Terbush]
8399 - Make wrapper work for files on NFS filesystem.
8400 - Fix portability problem of MAXPATHLEN.
8401 - Fix array overrun problem in clean_env().
8402 - Fix allocation of PATH environment variable
8404 *) Removed extraneous blank line is description of mod_status chars.
8407 *) Logging of errors from the call_exec routine simply went nowhere,
8408 since the logfile fd has been closed, so now we send them to stderr.
8409 [Harald T. Alvestrand]
8411 *) Fixed core dump when DocumentRoot is a CGI.
8412 [Ben Laurie, reported by geddis@tesserae.com]
8414 *) Fixed potential file descriptor leak in mod_asis; updated it and
8415 http_core to use pfopen/pfclose instead of fopen/fclose.
8416 [Randy Terbush and Roy Fielding]
8418 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
8419 as the DEC Alpha which is 64-bit but uses 32-bit ints.
8420 [Dean Gaudet and Ken Coar]
8422 *) Return a 302 response code to the client when sending a redirect
8423 due to a missing trailing '/' on a directory instead of a 301; now
8424 it is cacheable. [Markus Gyger]
8426 *) Fix condition where, if a bad directive occurs in .htaccess, and
8427 sub_request() goes first to this directory, then log_reason() will
8428 SIGSEGV because it doesn't have initialized r->per_dir_config.
8429 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
8431 *) Fix handling of lang_index in is_variant_better(). This was
8432 causing problems which resulted in the server sending the
8433 wrong language document in some cases. [Petr Lampa]
8435 *) Remove free() from clean_env() in suexec wrapper. This was nuking
8436 the clean environment on some systems.
8438 *) Tweak byteserving code (e.g. serving PDF files) to work around
8439 bugs in Netscape Navigator and Microsoft Internet Explorer.
8440 Emit Content-Length header when sending multipart/byteranges.
8443 *) Port to HI-UX/WE2. [Nick Maclaren]
8445 *) Port to HP MPE operating system for HP 3000 machines
8446 [Mark Bixby <markb@cccd.edu>]
8448 *) Fixed bug which caused a segmentation fault if only one argument
8449 given to RLimit* directives. [Ed Korthof]
8451 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
8453 *) Improved buffered output to the client by delaying the flush decision
8454 until the BUFF code is actually about to read the next request.
8455 This fixes a problem introduced in 1.2b5 with clients that send
8456 an extra CRLF after a POST request. Also improved chunked output
8457 performance by combining writes using writev() and removing as
8458 many bflush() calls as possible. NOTE: Platforms without writev()
8459 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
8460 or Configure, unless we have already done so. [Dean Gaudet]
8462 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
8464 *) Fixed mod_info output corruption bug introduced by buffer overflow
8465 fixes. [Dean Gaudet]
8467 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
8468 for the special case of a 304 response. [Paul Sutton]
8470 *) Improved handling of TRACE method by bypassing normal method handling
8471 and header parsing routines; fixed Allow response to always allow TRACE.
8474 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
8476 *) Cleaned-up some of the generated HTML. [Ken Coar]
8478 Changes with Apache 1.2b6
8480 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
8482 *) Fix typo introduced in fix for potential infinite loop around
8483 accept() in child_main(). This change caused the rev to 1.2b6.
8484 1.2b5 was never a public beta.
8486 Changes with Apache 1.2b5
8488 *) Change KeepAlive semantics (On|Off instead of a number), add
8489 MaxKeepAliveRequests directive. [Alexei Kosut]
8491 *) Various NeXT compilation patches, as well as a change in
8492 regex/regcomp.c since that file also used a NEXT define.
8495 *) Allow * to terminate the end of a directory match in mod_dir.
8496 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
8498 *) Don't call can_exec() if suexec_enabled. Calling this requires
8499 scripts executed by the suexec wrapper to be world executable, which
8500 defeats one of the advantages of running the wrapper. [Randy Terbush]
8502 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
8505 *) Migration from sprintf() to snprintf() to avoid buffer
8506 overflows. [Marc Slemko]
8508 *) Provide portable snprintf() implementation (ap_snprintf)
8509 as well as *cvt family. [Jim Jagielski]
8511 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
8514 *) Remove mod_fastcgi.c from the distribution. This module appears
8515 to be maintained more through the Open Market channels and should
8516 continue to be easily available at http://www.fastcgi.com/
8518 *) Fixed bug in modules/Makefile that wouldn't allow building in more
8519 than one subdirectory (or cleaning, either). [Jeremy Laidman]
8521 *) mod_info assumed that the config files were relative to ServerRoot.
8524 *) CGI scripts called as an error document resulting from failed
8525 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
8527 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
8530 *) Properly check errno to prevent display of a directory index
8531 when server receives a long enough URL to confuse stat().
8534 *) Several security enhancements to suexec wrapper. It is _highly_
8535 recommended that previously installed versions of the wrapper
8536 be replaced with this version. [Randy Terbush, Jason Dour]
8538 - ~user execution now properly restricted to ~user's home
8539 directory and below.
8540 - execution restricted to UID/GID > 100
8541 - restrict passed environment to known variables
8542 - call setgid() before initgroups() (portability fix)
8543 - remove use of setenv() (portability fix)
8545 *) Add HTTP/1.0 response forcing. [Ben Laurie]
8547 *) Add access control via environment variables. [Ben Laurie]
8549 *) Add rflush() function. [Alexei Kosut]
8551 *) remove duplicate pcalloc() call in new_connection().
8553 *) Fix incorrect comparison which could allow number of children =
8554 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
8555 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
8557 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
8558 AIX PS/2, CONVEXOS. [Jim Jagielski]
8560 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
8561 It's more portable. [Martin Kraemer]
8563 *) Replace references to make in Makefile.tmpl with $(MAKE).
8566 *) Add ProxyBlock directive w/IP address caching. Add IP address
8567 caching to NoCache directive as well. ProxyBlock works with all
8568 handlers; NoCache now also works with FTP for anonymous logins.
8569 Still more code cleanup. [Chuck Murcko]
8571 *) Add "header parse" API hook [Ben Laurie]
8573 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
8575 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
8577 *) Correctly allow access and auth directives in <Files> sections in
8578 server config files. [Alexei Kosut]
8580 *) Fix bug with ServerPath that could cause certain files to be not
8581 found by the server. [Alexei Kosut]
8583 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
8584 double-quote from text and so that it properly checks for unsupported
8585 status codes using the new index_of_response interface. [Roy Fielding]
8587 *) Multiple fixes to the lingering_close code in order to avoid being
8588 interrupted by a stray timeout, to avoid lingering on a connection
8589 that has already been aborted or never really existed, to ensure that
8590 we stop lingering as soon as any error condition is received, and to
8591 prevent being stuck indefinitely if the read blocks. Also improves
8592 reporting of error conditions. [Marc Slemko and Roy Fielding]
8594 *) Fixed initialization of parameter structure for sigaction.
8595 [mgyger@itr.ch, Adrian Filipi-Martin]
8597 *) Fixed reinitializing the parameters before each call to accept and
8598 select, and removed potential for infinite loop in accept.
8599 [Roy Fielding, after useful PR from adrian@virginia.edu]
8601 *) Fixed condition where, if a child fails to fork, the scoreboard would
8602 continue to say SERVER_STARTING forever. Eventually, the main process
8603 would refuse to start new children because count_idle_servers() will
8604 count those SERVER_STARTING entries and will always report that there
8605 are enough idle servers. [Phillip Vandry]
8607 *) Fixed bug in bcwrite regarding failure to account for partial writes.
8608 Avoided calling bflush() when the client is pipelining requests.
8609 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
8611 *) Added description of "." mode in server-status [Jim Jagielski]
8613 Changes with Apache 1.2b4
8615 *) Fix possible race condition in accept_mutex_init() that
8616 could leave a small security hole open allowing files to be
8617 overwritten in cases where the server UID has write permissions.
8620 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
8622 *) Fix portablity problem in util_script where ARG_MAX may not be
8623 defined for some systems.
8625 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
8628 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
8629 style magic #! token for better script portability. [Garey Smiley]
8631 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
8632 execution for ~userdir CGI. [Jason Dour]
8634 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
8636 *) Fix month off by one in suexec wrapper logging.
8638 Changes with Apache 1.2b3:
8640 *) Fix error in mod_cgi which could cause resources not to be properly
8641 freed, or worse. [Dean Gaudet]
8643 *) Fix find_string() NULL pointer dereference. [Howard Fear]
8645 *) Add set_flag_slot() at the request of Dirk and others.
8648 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
8650 *) Add changes to improve the error message given for invalid
8651 ServerName parameters. [Dirk vanGulik]
8653 *) Add "Authoritative" directive for Auth modules that don't
8654 currently have it. This gives admin control to assign authoritative
8655 control to an authentication scheme and allow "fall through" for
8656 those authentication modules that aren't "Authoritative" thereby
8657 allowing multiple authentication mechanisms to be chained.
8660 *) Remove requirement for ResourceConfig/AccessConfig if not using
8661 the three config file layout. [Randy Terbush]
8663 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
8665 *) Changes to suexec wrapper to fix the following problems:
8666 1. symlinked homedirs will kill ~userdirs.
8667 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8668 3. CGI command lines paramters problems
8669 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8670 [Randy Terbush, Jason Dour]
8672 *) Change create_argv() to accept variable arguments. This fixes
8673 a problem where arguments were not getting passed to the CGI via
8674 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8676 *) Collapse multiple slashes in path URLs to properly apply
8677 handlers defined by <Location>. [Alexei Kosut]
8679 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8681 *) Improve the accuracy of request duration timings by setting
8682 r->request_time in read_request_line() instead of read_request().
8685 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8686 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8688 *) Add the ability to pass different Makefile.tmpl files to Configure
8689 using the -make flag. [Rob Hartill]
8691 *) Fix coredump triggered when sending a SIGHUP to the server caused
8692 by an assertion failure, in turn caused by an uninitialised field in a
8696 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8697 PATH_INFO from previous versions of Apache (in certain situations,
8698 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
8699 [later removed in 1.2b11]
8701 *) Add rwrite() function to API to allow for sending strings of
8702 arbitrary length. [Doug MacEachern]
8704 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
8706 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
8707 NeXT. [Jim Jagielski]
8709 *) Removed recent modification to promote the status code on internal
8710 redirects, since the correct fix was to change the default log format
8711 in mod_log_config so that it outputs the original status. [Rob Hartill]
8713 Changes with Apache 1.2b2:
8715 *) Update set_signals() to use sigaction() for setting handlers.
8716 This appears to fix a re-entrant problem in the seg_fault()
8717 bus_error() handlers. [Randy Terbush]
8719 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8721 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8723 *) proxy_http.c bugfixes: [Chuck Murcko]
8724 1) fixes possible NULL pointer reference w/NoCache
8725 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8726 host would cache nothing if it was in the local domain,
8727 and the local domain was in the NoCache list)
8728 3) Adds Host: header when not available
8729 4) Some code cleanup and clarification
8731 *) mod_include.c bugfixes:
8732 1) Fixed an ommission that caused include variables to not
8733 be parsed in config errmsg directives [Howard Fear]
8734 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8735 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8736 4) Allow backslash-escaping to all quoted text
8737 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8738 5) Pass variable to command line if not set in XSSI's env
8741 *) Fix infinite loop when processing Content-language lines in
8742 type-map files. [Alexei Kosut]
8744 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8746 *) Fixed problem in set_[user|group] that prevented CGI execution
8747 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8749 *) Added PORTING information file. [Jim Jagielski]
8751 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8753 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8755 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8756 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8758 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8759 which caused problems of systems where socket s_addr is >32bits.
8761 *) Added comment to explain (r->chunked = 1) side-effect in
8762 http_protocol.c [Roy Fielding]
8764 *) Replaced use of index() in mod_expires.c with more appropriate
8765 and portable isdigit() test. [Ben Laurie]
8767 *) Updated Configure for ...
8768 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8769 *-dg-dgux* (bad pattern match)
8770 QNX (DEF_WANTHSREGEX=yes)
8771 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8774 and added some user diagnostic info. [Ben Laurie]
8776 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8777 for better portability. [Jim Jagielski]
8779 *) Updated helpers/GuessOS for ...
8780 SCO 5 (recognize minor releases)
8781 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8782 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8783 IRIX64 (-sgi-irix64)
8784 ULTRIX (-unknown-ultrix)
8785 SINIX (-whatever-sysv4)
8786 NCR Unix (-ncr-sysv4)
8787 and fixed something in helpers/PrintPath [Ben Laurie]
8789 Changes with Apache 1.2b1
8791 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8793 Changes with Apache 1.1.1
8795 *) Fixed bug where Cookie module would make two entries in the
8796 logfile for each access [Mark Cox]
8798 *) Fixed bug where Redirect in .htaccess files would cause memory
8799 leak. [Nathan Neulinger]
8801 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8803 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8805 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8807 Changes with Apache 1.1.0
8809 *) Bring NeXT support up to date. [Takaaki Matsumoto]
8811 *) Bring QNX support up to date. [Ben Laurie]
8813 *) Make virtual hosts default to main server keepalive parameters.
8814 [Alexei Kosut, Ben Laurie]
8816 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8818 *) Fix missing address family for connect, also remove unreachable statement
8819 in mod_proxy. [Ben Laurie]
8821 *) mod_env now turned on by default in Configuration.tmpl.
8823 *) Bugs which were fixed:
8824 a) yet more mod_proxy bugs [Ben Laurie]
8825 b) CGI works again with inetd [Alexei Kosut]
8826 c) Leading colons were stripped from passwords [osm@interguide.com]
8827 d) Another fix to multi-method Limit problem [jk@tools.de]
8829 Changes with Apache 1.1b4
8831 *) r->bytes_sent variable restored. [Robert Thau]
8833 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8835 *) More possibly unsecure programs removed from the support directory.
8837 *) More mod_auth_msql authentication improvements.
8839 *) VirtualHosts based on Host: headers no longer conflict with the
8842 *) OS/2 compatibility enhancements. [Gary Smiley]
8844 *) POST now allowed to directory index CGI scripts.
8846 *) Actions now work with files of the default type.
8848 *) Bugs which were fixed:
8849 a) more mod_proxy bugs
8850 b) early termination of inetd requests
8851 c) compile warnings on several systems
8852 d) problems when scripts stop reading output early
8854 Changes with Apache 1.1b3
8856 *) Much of cgi-bin and all of cgi-src has been removed, due to
8857 various security holes found and that we could no longer support
8860 *) The "Set-Cookie" header is now special-cased to not merge multiple
8861 instances, since certain popular browsers can not handle multiple
8862 Set-Cookie instructions in a single header. [Paul Sutton]
8864 *) rprintf() added to buffer code, occurrences of sprintf removed.
8867 *) CONNECT method for proxy module, which means tunneling SSL should work.
8868 (No crypto needed) Also a NoCache config directive.
8870 *) Several API additions: pstrndup(), table_unset() and get_token()
8871 functions now available to modules.
8873 *) mod_imap fixups, in particular Location: headers are now complete
8876 *) New "info" module which reports on installed module set through a
8877 special URL, a la mod_status.
8879 *) "ServerPath" directive added - allows for graceful transition
8880 for Host:-header-based virtual hosts.
8882 *) Anonymous authentication module improvements.
8884 *) MSQL authentication module improvements.
8886 *) Status module design improved - output now table-based. [Ben Laurie]
8888 *) htdigest utility included for use with digest authentication
8891 *) mod_negotiation: Accept values with wildcards to be treated with
8892 less priority than those without wildcards at the same quality
8893 value. [Alexei Kosut]
8895 *) Bugs which were fixed:
8896 a) numerous mod_proxy bugs
8897 b) CGI early-termination bug [Ben Laurie]
8898 c) Keepalives not working with virtual hosts
8899 d) RefererIgnore problems
8900 e) closing fd's twice in mod_include (causing core dumps on
8901 Linux and elsewhere).
8903 Changes with Apache 1.1b2
8906 a) core dumps in mod_digest
8907 b) truncated hostnames/ip address in the logs
8908 c) relative URL's in mod_imap map files
8910 Changes with Apache 1.1b1
8912 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
8914 Changes with Apache 1.0.3
8916 *) Internal redirects which occur in mod_dir.c now preserve the
8917 query portion of a request (the bit after the question mark).
8920 *) Escape active characters '<', '>' and '&' in html output in
8921 directory listings, error messages and redirection links.
8924 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
8926 *) Fix for POSIX compliance in waiting for processes in alloc.c.
8929 *) setsockopt no longer takes a const declared argument [Martijn Koster]
8931 *) Reset timeout timer after each successful fwrite() to the network.
8932 This patch adds a reset_timeout() procedure that is called by
8933 send_fd() to reset the timeout ever time data is written to the net.
8936 *) timeout() signal handler now checks for SIGPIPE and reports
8937 lost connections in a more user friendly way. [Rob Hartill]
8939 *) Location of the "scoreboard" file which used to live in /tmp is
8940 now configurable (for OSes that can't use mmap) via ScoreBoardFile
8941 which works similar to PidFile (in httpd.conf) [Rob Hartill]
8943 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
8945 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
8946 which caused a SEGV with cookies enabled
8948 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
8951 *) Log the UNIX textual error returned by some system calls, in
8952 particular errors from accept() [David Robinson]
8954 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
8956 Changes with Apache 1.0.2
8958 *) patch to get Apache compiled on UnixWare 2.x, recommended as
8959 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
8961 *) Fix get_basic_auth_pw() to set the auth_type of the request.
8964 *) past changes to http_config.c to only use the
8965 setrlimit function on systems defining RLIMIT_NOFILE
8966 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
8967 for SUNOS and prototypes the needed functions.
8969 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
8972 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
8974 *) Merge multiple headers from CGI scripts instead of taking last
8975 one. [David Robinson]
8977 *) Add support for SCO 5. [Ben Laurie]
8979 Changes with Apache 1.0.1
8981 *) Silence mod_log_referer and mod_log_agent if not configured
8984 *) Recursive includes can occur if the client supplies PATH_INFO data
8985 and the server provider uses relative links; as file.html
8986 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
8988 *) The replacement for initgroups() did not call {set,end}grent(). This
8989 had two implications: if anything else used getgrent(), then
8990 initgroups() would fail, and it was consuming a file descriptor.
8993 *) On heavily loaded servers it was possible for the scoreboard to get
8994 out of sync with reality, as a result of a race condition.
8995 The observed symptoms are far more Apaches running than should
8996 be, and heavy system loads, generally followed by catastrophic
8997 system failure. [Ben Laurie]
8999 *) Fix typo in license. [David Robinson]
9001 Changes with Apache 1.0.0 23 Nov 1995
9003 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9005 Changes with Apache 0.8.16 05 Nov 1995
9007 *) New man page for 'httpd' added to support directory [David Robinson]
9009 *) .htgroup files can have more than one line giving members for a
9010 given group (each must have the group name in front), for NCSA
9011 back-compatibility [Robert Thau]
9013 *) Mutual exclusion around accept() is on by default for SVR4 systems
9014 generally, since they generally can't handle multiple processes in
9015 accept() on the same socket. This should cure flaky behavior on
9016 a lot of those systems. [David Robinson]
9018 *) AddType, AddEncoding, and AddLanguage directives take multiple
9019 extensions on a single command line [David Robinson]
9021 *) UserDir can be disabled for a given virtual host by saying
9022 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9023 that this didn't work. [David Robinson]
9025 *) Compiles on QNX [Ben Laurie]
9027 *) Corrected parsing of ctime time format [David Robinson]
9029 *) httpd does a perror() before exiting if it can't log its pid
9030 to the PidFile, to make diagnosing the error a bit easier.
9033 *) <!--#include file="..."--> can no longer include files in the
9034 parent directory, for NCSA back-compatibility. [David Robinson]
9036 *) '~' is *not* escaped in URIs generated for directory listings
9039 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9041 *) Fixed bug involving handling URIs with escaped %-characters
9042 in redirects [David Robinson]
9044 Changes with Apache 0.8.15 14 Oct 1995
9046 *) Switched to new, simpler license
9048 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9050 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9052 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9054 *) Correctly handles internal redirects to files with names containing '%'
9057 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9059 *) Use geteuid() rather than getuid() to see if we have root privilege,
9060 so that server correctly resets privilege if run setuid root. [Andrew
9063 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9066 *) Fix relative URLs in imagemap files [Randy Terbush]
9068 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9071 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9072 entries all name the same one. [David Robinson]
9074 *) Fix directory listings with filenames containing unusual characters
9077 *) Better URI-escaping for generated URIs in directories with filenames
9078 containing unusual characters [Ben Laurie]
9080 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9082 *) Unblock alarms on error return from spawn_child() [David Robinson]
9084 *) Sample Config files have extra note for SCO users [Ben Laurie]
9086 *) Configuration has note for HP-UX users [Rob Hartill]
9088 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9090 *) Nuked bogus #define in httpd.h [David Robinson]
9092 *) Better test for whether a system has setrlimit() [David Robinson]
9094 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9096 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9099 Changes with Apache 0.8.14 19 Sep 1995
9101 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9103 *) AddDescription works (better) [Ben Laurie]
9105 *) Leaves an intelligible error diagnostic when it can't set group
9106 privileges on standalone startup [Andrew Wilson]
9108 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9109 that machine, which claims to be BSD but does not support RLIMIT.
9112 *) gcc -Wall no longer complains about an unused variable when util.c
9113 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9115 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9117 Changes with Apache 0.8.13 07 Sep 1995
9119 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9121 *) Have built-in imagemap code recognize & honor Point directive [James
9124 *) Generate cleaner directory listings in directories with a mix of
9125 long and short filenames [Rob Hartill]
9127 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9129 *) Properly default ServerName for virtual servers [Robert Thau]
9131 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9132 Paul Richards and a cast of thousands...]
9134 *) On self-identified BSD systems (we don't try to guess any more),
9135 allocate a few extra file descriptors per virtual host with setrlimit,
9136 if we can, to avoid running out. [Randy Terbush]
9138 *) Write 22-character lock file name into buffer with enough space
9139 on startup [Konstantin Olchanski]
9141 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9144 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9146 *) Suppress -Wall warning by initializing variable in negotiation code
9147 [Tobias Weingartner]
9149 Changes with Apache 0.8.12 31 Aug 1995
9151 *) Doesn't pause three seconds after including a CGI script which is
9152 too slow to die off (this is done by not even trying to kill off
9153 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9154 after the entire document has been processed). [Robert Thau]
9156 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9158 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9160 *) Allows .htaccess files to override <Directory> sections naming the
9161 same directory [David Robinson]
9163 *) Removed an efficiency hack in sub_req_lookup_uri which was
9164 causing certain extremely marginal cases (e.g., ScriptAlias of a
9165 *particular* index.html file) to fail. [David Robinson]
9167 *) Doesn't log an error when the requested URI requires
9168 authentication, but no auth header line was supplied by the
9169 client; this is a normal condition (the client doesn't no auth is
9170 needed here yet). [Robert Thau]
9172 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9174 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9176 *) RFC931 code no longer passes out name of prior clients on current
9177 requests if the current request came from a server that doesn't
9178 do RFC931. [David Robinson]
9180 *) Configuration script accepts "Module" lines with trailing whitespace.
9183 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9185 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9187 Changes with Apache 0.8.11 24 Aug 1995
9189 *) Wildcard <Directory> specifications work. [Robert Thau]
9191 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9193 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9194 the file being requested itself, in addition to the directories leading
9195 up to it. [Robert Thau]
9197 *) Logs access failures due to symlink checks or invalid client address
9198 in the error log [Roy Fielding, Robert Thau]
9200 *) Symlink checks deal correctly with systems where lstat of
9201 "/path/to/some/link/" follows the link. [Thau, Fielding]
9203 *) Doesn't reset DirectoryIndex to 'index.html' when
9204 other directory options are set in a .htaccess file. [Robert Thau]
9206 *) Clarified init code and nuked bogus warning in mod_access.c
9209 *) Corrected several directives in sample srm.conf
9210 --- includes corrections to directory indexing icon-related directives
9211 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9212 icons for encodings right, and turning on AddEncoding by default).
9215 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9218 *) INSTALL & README mention "contributed modules" directory [Brian
9221 *) Fixed English in the license language... "for for" --> "for".
9224 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9225 mod_alias.c, merging it almost completely with handling of Alias, and
9226 adding a 'notes' field to the request_rec which allows the CGI module
9227 to discover whether the Alias module has put this request through
9228 ScriptAlias (which it needs to know for back-compatibility, as the old
9229 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9232 Changes with Apache 0.8.10 18 Aug 1995
9234 *) AllowOverride applies to the named directory, and not just
9235 subdirectories. [David Robinson]
9237 *) Do locking for accept() exclusion (on systems that need it)
9238 using a special file created for the purpose in /usr/tmp, and
9239 not the error log; using the error log causes real problems
9240 if it's NFS-mounted; this is known to be the cause of a whole
9241 lot of "server hang" problems with Solaris. [David Robinson;
9242 thanks to Merten Schumann for help diagnosing the problem].
9244 Changes with Apache 0.8.9 12 Aug 1995
9246 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9248 *) Nested includes see environment variables of the including document,
9249 for NCSA bug-compatibility (some sites have standard footer includes
9250 which try to print out the last-modified date). [Eric Hagberg/Robert
9253 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9254 URI as a CGI script, even if it would have been treated as something
9255 else if requested directly, for NCSA back-compatibility. (Note that
9256 this means that people who know the name of the script can see the
9257 code just by asking for it). [Robert Thau]
9259 *) New version of dbmmanage script included in support directory as
9262 *) Check if scoreboard file couldn't be opened, and say so, rather
9263 then going insane [David Robinson]
9265 *) POST to CGI works on A/UX [Jim Jagielski]
9267 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9269 *) NCSA server push works properly --- the Arena bug compatibility
9270 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9271 if you still want the workaround). [Rob Hartill]
9273 *) If client didn't submit any Accept-encodings, ignore encodings in
9274 content negotiation. (NB this will all have to be reworked anyway
9275 for the new HTTP draft). [Florent Guillaume]
9277 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9279 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9281 *) Give Redirect priority over Alias, for NCSA bug compatibility
9284 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9285 paralleling earlier bug fix for CGI [David Robinson]
9287 *) If DBM auth is improperly configured, report a server error and don't
9290 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9291 it seems to work well enough without it (even in a 10 hits/sec
9292 workout), and the overhead for the locking under A/UX is
9293 alarmingly high (though it is very low on other systems).
9294 [Eric Hagberg, Jim Jagielski]
9296 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9298 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9299 Behlendorf/Eric Hagberg]
9301 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9303 *) Compiles clean on NEXT [Rob Hartill]
9305 *) Compiles clean on SGI [Robert Thau]
9307 Changes with Apache 0.8.8 08 Aug 1995
9309 *) SunOS library prototypes now never included unless explicitly
9310 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9311 people using GNU libc on SunOS are screwed by prototypes for the
9314 (Those who wish to compile clean with gcc -Wall on a standard
9315 SunOS setup need the prototypes, and may obtain them using
9316 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9317 with nonstandard libraries are presumably competent to make their
9320 *) Strips trailing '/' characters off both args to the Alias command,
9321 to make 'Alias /foo/ /bar/' work.
9323 Changes with Apache 0.8.7 03 Aug 1995
9325 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9326 [reported by David Robinson]
9328 *) Compiles clean on OSF/1 [David Robinson]
9330 *) Added some of the more recent significant changes (AddLanguage stuff,
9331 experimental LogFormat support) to CHANGES file in distribution root
9334 Changes with Apache 0.8.6 02 Aug 1995
9336 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9337 (If you actually wanted a conditional GET which bypassed the cache, you
9338 couldn't get it). [Reported by Roy Fielding]
9340 *) Properly terminate headers on '304 Not Modified' replies to conditional
9341 GETs --- no browser we can find cares much, but the CERN proxy chokes.
9342 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
9344 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
9346 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
9347 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
9348 and older versions don't set the __SUNPRO_C preprocessor variable). On
9349 all other systems, these are never used anyway. [Reported by Mark Cox].
9351 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9353 Changes with Apache 0.8.5 01 Aug 1995
9355 *) Added last-minute configurable log experiment, as optional module
9357 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9358 properly. (One-line fix to http_protocol.c).
9360 *) Work around bogus behavior when reloading from Netscape.
9361 It's Netscape's bug --- for some reason they expect a request with
9362 If-modified-since: to not function as a conditional GET if it also
9363 comes with Pragma: no-cache, which is way out of line with the HTTP
9364 spec (according to Roy Fielding, the redactor).
9366 *) Added parameter to set maximum number of server processes.
9368 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9371 *) IdentityCheck bugfix [Chuck Murcko].
9373 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
9375 *) More sample config file corrections; add extension to AddType for
9376 *.asis, move AddType generic description to its proper place, and
9377 fix miscellaneous typos. [ Alexei Kosut ]
9379 *) Deleted the *other* reference to the regents from the Berkeley
9380 legal disclaimer (everyplace).
9382 *) Nuked Shambhala name from src/README; had already cleaned it out
9385 Changes with Apache 0.8.4
9387 *) Changes to server-pool management parms --- renamed current
9388 StartServers to MinSpareServers, created separate StartServers
9389 parameter which means what it says, and renamed MaxServers to
9390 MaxSpareServers (though the old name still works, for NCSA 1.4
9391 back-compatibility). The old names were generally regarded as
9392 too confusing. Also altered "docs" in sample config files.
9394 *) More improvements to default config files ---
9395 sample directives (commented out) for XBitHack, BindAddress,
9396 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
9397 defaults, AddTypes for send-as-is and imagemap magic types, and
9398 improvements to samples for DirectoryIndex [Alexei Kosut]
9400 *) Yet more improvements to default config files --- changes to
9401 Alexei's sample AddLanguage directives, and sample LanguagePriority
9402 [ Florent Guillaume ]
9404 *) Set config file locations properly if not set in httpd.conf
9407 *) Don't escape URIs in internal redirects multiple times; don't
9408 do that when translating PATH_INFO to PATH_TRANSLATED either.
9411 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
9413 Changes with Apache 0.8.3
9415 *) Edited distribution README to *briefly* summarize installation
9416 procedures, and give a pointer to the INSTALL file in the src/
9419 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
9420 recent NCSA distributions.
9422 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
9423 exist for the same directory, use both and don't segfault. [Reported
9426 *) Proper makefile dependencies [David Robinson]
9428 *) Note (re)starts in error log --- reported by Rob Hartill.
9430 *) Only call no2slash() after get_path_info() has been done, to
9431 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
9432 reported by Andrew Wilson, though this one is probably a real bug]
9434 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
9435 dump core when Referer is not supplied. [Randy Terbush]
9437 *) Lightly edited sample config files to refer people to our documentation
9438 instead of NCSA's, and to list Rob McCool as *original* author (also
9439 deleted his old, and no doubt non-functional email address). Would be
9440 nice to have examples of new features...
9442 Changes with Apache 0.8.2 19 Jul 1995
9444 *) Added AddLanuage code [Florent Guillaume]
9446 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
9448 *) All sorts of problems when MultiViews finds a directory. It would
9449 be nice if mod_dir.c was robust enough to handle that, but for now,
9450 just punt. [reported by Brian Behlendorf]
9452 *) Wait for all children on restart, to make sure that the old socket
9453 is gone and we can reopen it. [reported by Randy Terbush]
9455 *) Imagemap module is enabled in default Configuration
9457 *) RefererLog and UserAgentLog modules properly default the logfile
9460 *) Mark Cox's mod_cookies added to the distribution as an optional
9461 module (commented out in the default Configuration, and noted as
9462 an experiment, along with mod_dld). [Mark Cox]
9464 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
9466 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
9468 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
9470 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
9473 Changes with Apache 0.8.1
9475 *) New imagemap module [Randy Terbush]
9477 *) Replacement referer log module with NCSA-compatible RefererIgnore
9478 [Matthew Gray again]
9480 *) Don't mung directory listings with very long filenames.
9483 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
9485 *) New config script. See INSTALL for info. [Robert Thau]
9487 *) Scoreboard mechanism for regulating the number of extant server
9488 processes. MaxServers and StartServers defaults are the same as
9489 for NCSA, but the meanings are slightly different. (Actually,
9490 I should probably lower the MaxServers default to 10).
9492 Before asking for a new connection, each server process checks
9493 the number of other servers which are also waiting for a
9494 connection. If there are more than MaxServers, it quietly dies
9495 off. Conversely, every second, the root, or caretaker, process
9496 looks to see how many servers are waiting for a new connection;
9497 if there are fewer than StartServers, it starts a new one. This
9498 does not depend on the number of server processes already extant.
9499 The accounting is arranged through a "scoreboard" file, named
9500 /tmp/htstatus.*, on which each process has an independent file
9501 descriptor (they need to seek without interference).
9503 The end effect is that MaxServers is the maximum number of
9504 servers on an *inactive* server machine, but more will be forked
9505 off to handle unusually heavy loads (or unusually slow clients);
9506 these will die off when they are no longer needed --- without
9507 reverting to the overhead of full forking operation. There is a
9508 hard maximum of 150 server processes compiled in, largely to
9509 avoid forking out of control and dragging the machine down.
9510 (This is arguably too high).
9512 In my server endurance tests, this mechanism did not appear to
9513 impose any significant overhead, even after I forced it to put the
9514 scoreboard file on a normal filesystem (which might have more
9515 overhead than tmpfs). [Robert Thau]
9517 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
9520 *) Read .htaccess files even in directory with <Directory> section.
9521 (Former incompatibility noted on mailing list, now fixed). [Robert
9524 *) "HEAD /" gives the client a "Bad Request" error message, rather
9525 than trying to send no body *and* no headers. [Cliff Skolnick].
9527 *) Don't produce double error reports for some very obscure cases
9528 mainly involving auth configuration (the "all modules decline to
9529 handle" case which is a sure sign of a server bug in most cases,
9530 but also happens when authentication is badly misconfigured).
9533 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
9534 it's *for*, and this sort of thing really shouldn't be cluttering
9535 up the Makefile). [Robert Thau]
9537 *) Incidental code cleanups in http_main.c --- stop dragging
9538 sa_client around; just declare it where used. [Robert Thau]
9540 *) Another acc-related fix. (It doesn't like const char
9541 in some places...). [Mark Cox]
9543 Changes with Shambhala 0.6.1 13 Jul 1995
9545 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
9546 Also, fixed auth typo in http_protocol.c unmasked by this fix.
9548 *) Compiles clean with acc on SunOS [Paul Sutton]
9550 *) Reordered modules in modules.c so that Redirect takes priority
9551 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
9552 believe it or not, he has an actual site with a ScriptAlias and
9553 a Redirect declared for the *exact same directory*. Even *my*
9554 compatibility fetish wouldn't motivate me to fix this if the fix
9555 required any effort, but it doesn't, so what the hey.
9557 *) Fixed to properly default several server_rec fields for virtual
9558 servers from the corresponding fields in the main server_rec.
9559 [Cliff Skolnick --- 'port' was a particular irritant].
9561 *) No longer kills off nph- child processes before they are
9562 finished sending output. [Matthew Gray]
9564 Changes with Shambhala 0.6.0 10 Jul 1995
9566 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
9567 the connection to the client in an "aborted" state, but otherwise
9568 allow whatever handlers are running to clean up. hard_timeout()s
9569 abort the request in progress completely; anything not tied to some
9570 resource pool cleanup will leak. They're still around because I
9571 haven't yet come up with a more elegant way of handling
9572 timeouts when talking to something that isn't the client. The
9573 default_handler and the dir_handler now use soft timeouts, largely
9574 so I can test the feature. [Robert Thau]
9576 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
9577 the case of log handlers dying prematurely is probably handled VERY
9578 gracelessly at this point, and if the logger stops reading input,
9579 the server will hang. (It is known to correctly restart the
9580 logging process on server restart; this is (should be!) going through
9581 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
9582 script). [Robert Thau]
9584 *) asis files supported (new module). [Robert Thau]
9586 *) IdentityCheck code is compiled in, but has not been tested. (I
9587 don't know anyone who runs identd). [Robert Thau]
9589 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
9590 came in with the request, for NCSA bug-compatibility. [Robert Thau]
9592 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
9594 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
9595 as timeouts are not in scope. [Robert Thau]
9597 *) quoted-string args in config files now handled correctly (doesn't drop
9598 the last character). [Robert Thau; reported by Randy Terbush]
9600 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
9601 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
9603 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
9604 default default type); the former default default behavior when all
9605 type-checkers defaulted had been a core dump. [Paul Sutton]
9607 *) Copy filenames out of the struct dirent when indexing
9608 directories. (On Linux, readdir() returns a pointer to the same
9609 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
9611 Changes with Shambhala 0.5.3 [not released]
9613 *) Default response handler notes "file not found" in the error log,
9614 if the file was not found. [Cliff Skolnick].
9616 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
9617 code no longer sets up bogus PATH_INFO which fakes out the directory
9618 handler). [Cliff Skolnick]
9620 Changes with Shambhala 0.5.2 06 Jul 1995
9622 *) Changes to http_main.c --- root server no longer plays silly
9623 games with SIGCHLD, and so now detects and replaces dying
9624 children. Child processes just die on SIGTERM, without taking
9625 the whole process group with them. Potential problem --- if any
9626 child process refuses to die, we hang in restart.
9627 MaxRequestsPerChild may still not work, but it certainly works
9628 better than it did before this! [Robert Thau]
9630 *) mod_dir.c bug fixes: ReadmeName and HeaderName
9631 work (or work better, at least); over-long description lines
9632 properly terminated. [Mark Cox]
9634 *) http_request.c now calls unescape_url() more places where it
9635 should [Paul Sutton].
9637 *) More directory handling bugs (reported by Cox)
9638 Parent Directory link is now set correctly. [Robert Thau]
9640 Changes with Shambhala 0.5.1 04 Jul 1995
9642 *) Generalized cleanup interface in alloc.c --- any function can be
9643 registered with alloc.c as a cleanup for a resource pool;
9644 tracking of files and file descriptors has been reimplemented in
9645 terms of this interface, so I can give it some sort of a test.
9648 *) More changes in alloc.c --- new cleanup_for_exec() function,
9649 which tracks down and closes all file descriptors which have been
9650 registered with the alloc.c machinery before the server exec()s a
9651 child process for CGI or <!--#exec-->. CGI children now get
9652 started with exactly three file descriptors open. Hopefully,
9653 this cures the problem Rob H. was having with overly persistent
9654 CGI connections. [Robert Thau]
9656 *) Mutual exclusion around the accept() in child_main() --- this is
9657 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
9658 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
9659 This uses fcntl(F_SETLK,...) on the error log descriptor because
9660 flock() on that descriptor won't work on systems which have BSD
9661 flock() semantics, including (I think) Linux 1.3 and Solaris.
9663 This does work on SunOS (when the server is idle, only one
9664 process in the pool is waiting on accept()); it *ought* to work
9665 on the other systems. [Robert Thau]
9667 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9669 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9671 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9673 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9674 be unnecessary if I go to the revised timeout-handling scheme).
9677 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9678 string) even if none came in with the request. [Robert Thau]
9680 *) CHANGES file added to distribution ;-).
9682 Changes with Shambhala 0.4.5
9684 *) mod_dld --- early dynamic loading support [rst]
9685 *) Add wildcard content handlers for XBITHACK; default_hander now
9686 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9687 *) XBITHACK supported as a wildcard content-handler, and
9688 configurable at run-time (not just at compile time, as in the
9689 "patchy server" releases) [rst]
9691 Changes with Shambhala 0.4.4 30 Jun 1995
9693 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9694 *) Handle Addtype x/y .z [rst, reported by Cox]
9696 Changes with Shambhala 0.4.3
9698 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
9699 synonymous [rst, terbush]
9701 Changes with Shambhala 0.4.1 28 Jun 1995
9703 *) First-cut virtual host implementation; some refit in the config
9704 reading code, and log management, was necessary to support this [rst]
9705 *) Sub-pool machinery, originally added to avoid excessive storage
9706 allocation on listings of large directories (which turned out to
9707 be the problem that the 0.3 storage accounting was added to
9708 find). Subrequests and mod_dir changed to use subpools. [rst]
9709 *) More memory debugging --- free list consistency checks. [rst]
9710 *) Added err_headers to request_rec, with support elsewhere [rst]
9711 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9713 Changes with Shambhala 0.3 19 Jun 1995
9715 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9716 *) Don't compile in mod_ai_backcompat by default
9717 *) Switch name of server from Apache to Shambhala in Makefile
9718 *) Add some accounting routines to track memory usage in the pools,
9721 Changes with Shambhala 0.2
9723 *) Set DOCUMENT_ROOT CGI variable
9724 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9725 *) Add critical section protection to handling of cleanup structures
9727 *) Significant code reorg within the server core to group related
9728 functions together [rst]
9729 *) Correctly handle clients that hang up before sending any request
9731 *) Replace dying child processes. [rst]
9733 Changes with Shambhala 0.1 12 Jun 1995
9735 Major rewrite of the pre-existing "patchy server" codebase, by
9736 Robert Thau (rst). Significant portions of the server code, such
9737 as configuration-file handling and HTTP authentication support,
9738 were ripped out and rewritten from scratch. Code that was not
9739 completely rewritten was significantly altered.
9741 Major changes with this release include:
9743 *) Introduction of the module API; in request handling, the central
9744 machinery just dispatches to various modules, which actually do
9745 most of the work. Configuration handling is similar --- modules
9746 declare their own commands, and the central machinery just
9749 API features from shambhala/0.1 were substantially unchanged in
9750 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9751 release, such as wildcard handlers and subpools, were added in
9752 subsequent Shambhala releases, and were also generally rst's
9755 *) This release included the following modules:
9757 mod_access (access control --- allow and deny directives),
9758 mod_alias (Alias and Redirect commands),
9759 mod_auth (straight HTTP authentication, based on flat-files)
9760 mod_auth_dbm (same, with dbm files)
9761 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9762 mod_common_log (CLF access logs; later renamed mod_log_common)
9763 mod_dir (directory indexing)
9764 mod_include (server-side includes)
9765 mod_mime (AddType directives)
9766 mod_negotiation (content negotiation)
9767 mod_userdir (support for users' public_html directories)
9769 It also included a mod_ai_backcompat, which was a private hack
9770 for back-compatibility with rst's own AI-lab servers.
9772 All of these modules were substantially complete, and functional
9773 or nearly so (a few, which implemented features not in use at
9774 Thau's site, required patches of a few lines).
9776 *) sub-request machinery, to allow modules to determine how other
9777 modules would assign MIME types to a given file, or optionally
9778 serve its content (this is heavily used by mod_dir, mod_include
9779 and mod_negotiation).
9781 *) Resource pool system for keeping track of memory allocated and
9782 files opened in service of a particular request. Much of the
9783 code in the modules (when they weren't rewrites) was adjusted to
9784 replace a pervasive convention of using fixed-size buffers on
9785 the stack with an equally pervasive convention of using memory
9786 allocated with palloc().
9788 *) Reorganization of data structures associated with a given
9789 request to eliminate use of global variables and the troublesome
9790 unmunge_name function (used in NCSA and early Apache releases to
9791 attempt to determine the URI which mapped to a given filename
9792 --- a difficult proposition, given that it is easy to produce
9793 setups in which multiple URIs map to the same file).
9795 *) Source files renamed and rearranged
9797 *) Very simple pre-forking behavior --- parent process forked off a
9798 fixed number of children, and then just waited for SIGHUP.
9800 *) Other more minor changes too numerous to list.
9802 This release included modified versions of a lot of code from the
9803 Apache 0.6.4 public release, plus an early pre-forking patch
9804 codeveloped by Robert Thau and Rob Hartill.
9806 Changes with Apache 0.7.3 20 Jun 1995
9808 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9809 were incorporated by Rob Hartill on the main branch while Robert Thau
9810 worked on the Shambhala rewrite above. Most were merged into the
9811 Shambala architecture after Apache 0.8.0.
9813 Changes with Apache 0.6.4 13 May 1995
9815 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9818 Changes with Apache 0.5.1 10 Apr 1995

9822 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
9825 Changes with Apache 0.3 24 Mar 1995
9827 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
9830 Changes with Apache 0.2 18 Mar 1995
9832 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
9833 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
9834 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
