1 Changes with Apache 2.0.23-dev
3 *) Solve many mod_ssl porting issues [far too many to detail.]
4 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
5 Doug MacEachern, William Rowe, Cliff Wooley, Ralf S. Engelschall]
7 *) More stall fixes for the threaded & worker mpm's.
8 Make mod_status output more accurate. Don't
9 count workers in processes which aren't actively
10 serving requests. [Greg Ames]
12 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
14 *) Add a single listener/multiple worker MPM. This MPM is
15 definately not fully correct, but it allows us to solve many
16 of the problems that exist in the threaded MPM. This is a
17 modified version of the threaded MPM. [Ryan Bloom]
19 *) Improve content generation throughout Apache, providing closer
20 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
21 Transitional specifications. [William Rowe]
23 Changes with Apache 2.0.22
25 *) Fix a problem where the threaded MPM stalls after restarts or
26 segfaults. Also prevent multiple active processes from using
27 the same scoreboard slot. [Greg Ames]
29 *) Apache/Win32 now fills in the service description with Apache's
30 server version string, including loaded and advertised modules.
33 *) Improved support for the Win32 build, to recover gracefully from
34 missing apr or apr-util directories or the awk interpreter,
35 create the proper cgi-bin examples, including a test-cgi.bat, and
36 fix the perl shebang line for printenv.pl, when installing from
37 the build environment. [William Rowe]
39 *) Fix a segfault in threaded.c caused by passing uninitialized
40 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
42 *) Use new APR number conversion functions to reduce CPU consumption
43 when setting the content length, and in mod_log_config.
46 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
47 where HEAD response headers were being repeated twice for
48 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
49 problem in the http_header filter was exposed by the recent rewrite
50 of the content_length filter. [Taketo Kabe, Bill Stoddard]
52 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
53 restarts. A garbage pointer to a vhost's server_rec from the
54 previous generation was being left around under certain
55 conditions. [Greg Ames]
57 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
58 used to appear as '(none', without the closing paren.
59 [Günter Knauf <eflash@gmx.net>]
61 *) Improve the exports generating awk script. In the past, we had
62 work around problems in the awk script by avoiding some #if and
63 #ifdefs. This has bitten us many times in generating the exports.c
64 file. This improvement allows corrects the header file parsing.
65 [Sander Striker <striker@apache.org>]
67 Changes with Apache 2.0.21
69 *) Resolve the Win32 htpasswd bug, where a file that existed would be
70 overwritten, regardless of the -c flag.
71 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
73 *) Introduce connection sub-pools into ab. Truncating the lifetime
74 of these allocations means that ab no longer perpetually grows
75 its working set, running out of memory on large request attempts.
78 *) Make scoreboard creation a hook. This allows management
79 modules to have access to the scoreboard at the time that it is
80 created, and at every restart request.
81 [Cody Sherr <csherr@covalent.net>]
83 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
84 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
85 daemon index actually used in the scoreboard. I also
86 updated the pertinent calls. [Paul J. Reder]
88 *) Win32: Prevent listening sockets from being inherited by
89 the Apache child process, CGI scripts, rotatelog process
90 etc. If the Apache child process segfaults, any processes
91 that the child started are not reaped. Prior to this fix,
92 these processes inherited the listening sockets which sometimes
93 prevented the restarted Apache child process from accepting
94 connections (ie, the server would hang).
97 *) Provide vhost and request strings when ExtendedStatus is on.
100 *) Fix some issues with the pod and prefork: check the pod *after*
101 processing a connection so that a server processing a time-
102 consuming request bails out as soon as practical; when the
103 parent process wakes up a server process via connect(), use an
104 APR timeout on the connect() so that we don't hang for a long
105 time if there aren't server processes around to do accept().
106 [Jeff Trawick, Greg Ames]
108 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
109 spends a lot of time in apr_table_get calls. Using the default
110 httpd.conf, the tables for languages and charsets are somewhat
111 large, so the time spent scanning them on each request is
112 significant. Replacing the tables with hash tables provides
113 a nice speedup. [Brian Pane <bpane@pacbell.net>]
115 *) Add two functions to allow modules to access random parts of the
116 scoreboard. This allows modules compiled for one MPM to access the
117 scoreboard, even if it the server was compiled for another MPM.
118 [Harrie Hazewinkel <harrie@covalent.net>]
120 Changes with Apache 2.0.20
122 *) Fix problem in content-length filter where the filter would
123 buffer all the output from a CGI before sending any bytes
124 down the filter stack to the network. This problem would cause
125 significant memory consumption if the CGIs generated
126 lots of bytes. [Bill Stoddard]
128 *) Get non-blocking CGI pipe reads working with the bucket brigades.
131 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
134 *) Fix a bug in the threaded MPM that would cause it to kill off all
135 workers immediately after starting if the number of workers started
136 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
138 Changes with Apache 2.0.19
140 *) Fix problem with threaded MPM. The problem was that if each child
141 process was busy serving a single long-lived request and the server
142 was sent a graceful restart signal, the server would stop serving
143 requests. This would happen because each child process would wait to
144 die until the last thread was done, and the parent wouldn't spawn any
145 new children until a process died. Now, the parent looks at the fact
146 that the children are dying gracefully, and starts new children.
147 Those new children only start enough threads to compliment the number
148 of threads in the other child process that shares the same spot in
149 the scoreboard. In this way, we make sure to never go over
150 MaxClients. [Ryan Bloom]
152 *) modified mod_negotiation and mod_autoindex to speed up by almost a
153 factor of two on apr_dir_read()-enhanced platforms, such as Win32
154 and OS2, by calling ap_sub_request_lookup_dirent() with the results
155 already provided by apr_dir_read(). [William Rowe]
157 *) mod_file_cache is now more robust to filtering and serves requests
158 slightly more efficiently. [Cliff Woolley]
160 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
161 Module was calling ap_rwrite() followed by ap_rflush() but the
162 served content was not being displayed in the browser. Inspection
163 of the output stream revealed that the first data chunk was
164 missing the trailing CRLF required by the RFC. [Bill Stoddard]
166 *) apxs no longer generates ap_send_http_header() in the example handler
168 *) Fix an ab problem which could cause a divide-by-zero exception
169 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
170 [Ian Holsman <ianh@cnet.com>]
172 *) Solve case-insensitive platforms' confusion about negotiated
173 filenames, allowing files of differnt case to match in choosing
174 the document to serve. [William Rowe]
176 *) Fix brokenness when ThreadsPerChild is higher than the built-in
177 limit. We left ap_threads_per_child at the higher value which
178 led to segfaults when doing certain scoreboard operations.
181 *) Fix seg faults and/or missing output from mod_include. The
182 default_handler was using the subrequest pool for files and
183 MMAPs, even though the associated APR structures typically
184 live longer than the subrequest. [Greg Ames]
186 *) Extend mod_setenvif to support specifying regular expressions
187 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
188 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
189 will cause HAVE_TS to be set if any of the request headers begins
190 with "TS" and has a value that begins with any character in the
191 set [a-z]. [Bill Stoddard]
193 *) httpd children now re-bind themselves to a random CPU on
194 multiprocessor systems on AIX via bindprocessor() in 2.0.
195 [Victor J. Orlikowski]
197 *) Fix htdigest. It would go into a loop in getline when adding
198 a second user. [Bill Stoddard]
200 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
202 *) Automatically generate httpd.exp for AIX.
203 DSOs now work again on AIX in 2.0
204 [Victor J. Orlikowski]
206 *) Add a new request hook, error_log. This phase allows modules
207 to act on the error log string _after_ it has been written
208 to the error log. The goal for this hook is to allow monitoring
209 modules to send the error string to the monitoring agent.
212 *) Modify mod_echo to make it use filters for input and output.
213 [Ryan Morgan <rmorgan@covalent.net>]
215 *) Extend mod_headers to support conditional driven Header
216 add, append and set. Use SetEnvIf to set an envar and conditionally
217 add/append/set headers based on this envar thusly:
219 SetEnvIf TSMyHeader value HAVE_TSMyHeader
220 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
222 If the request contains header "TSMyHeader: value" then header
223 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
226 *) Extend mod_headers to support using format specifiers on Header
227 add, append and set header values. Two format specifiers are supported:
229 %t - reports, in UTC microseconds since the epoch, when the
230 request was received.
232 %D - reports the time, in microseconds, between when the request was
233 received and the response sent.
236 Header add MyHeader "This request served in %D microseconds. %t"
238 results in a header being added to the response that looks like this:
240 MyHeader: This request served in D=5438 microseconds. t=991424704447256
244 *) Fix reset_filter(). We need to be careful how we remove filters.
245 If we set r->output_filters to NULL, we also have to reset the
246 connection's filters. [John Sterling]
248 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
250 *) Add a check to ap_die() to make sure the filter stack is sane and
251 contains the correct basic filters when an error occurs. This fixes
252 a problem where headers are not being sent on error. [John Sterling]
254 *) New Header directive 'echo' option. "Header echo regex" will
255 cause any headers received on the request that match regex to be
256 echoed to (included in) the response headers.
259 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
260 This prevented the inclusion of apr_compat.h. PR #7773
261 [Oleg Broytmann <phd@phd.pp.ru>]
263 *) Moved util_uri to the apr-util library. This required a bunch of
264 apr_name changes for the uri utility functions. [Justin Erenkrantz]
266 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
267 insert_filter phase so that other filters are not bypassed by default.
270 *) Reimplement mod_headers as an output filter. mod_headers can now
271 add custom headers to inbound requests using the RequestHeader directive
272 and to responses using the same old Header directive. [Graham Leggett]
274 Changes with Apache 2.0.18
276 *) Fix command-line processing so that if a bad argument is specified
277 Apache will exit. [Jeff Trawick]
279 *) Change the make targets and rules to be consistent in all of the
280 Apache-owned source trees. [Roy Fielding]
282 *) Fix processing of the TRACE method. Previously we passed bogus
283 parms to form_header_field() and it overlaid some vhost structures,
284 resulting in a segfault in check_hostalias().
285 [Greg Ames, Jeff Trawick]
287 *) Win32: Add support for reliable piped logs. If the logging process
288 goes down, Apache will automatically restart it. This function has
289 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
292 *) Do not start piped log processes during the config file
293 preflight. This change also circumvents a problem on
294 Windows where the rotatelog processes created during preflight
295 was not getting cleaned up properly.
298 *) add "Request Phase Participation" info to mod_info
301 *) Make first phase changes to the scoreboard data structures in
302 preparation for the rewriting of the scoreboard per my posted
303 design notes. [Paul J. Reder]
305 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
306 and apr-util, allow it to be overridden by the configure command-line
307 (default="--silent") and introduce LT_LDFLAGS to replace what we were
308 formerly abusing as LTFLAGS. [Roy Fielding]
310 *) Clean up the reporting of incorrect closing container tags.
311 [Barrie Slaymaker <barries@slaysys.com>]
313 *) Simplify the configure process by moving all libtool stuff to APR
314 and moving hints.m4 inline. [Roy Fielding]
316 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
317 of functions used by mod_proxy for export in the DLL
318 [Ian Holsman <IanH@cnet.com>]
320 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
321 request body from its stdin but no reqest body is being written to
322 the cgi. [Jeff Trawick]
324 *) mod_log_config: %c connection status incorrectly logged
325 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
328 *) Get mod_cern_meta working under Windows
331 *) Create Files, and thus MMAPs, out of the request pool, not the
332 connection pool. This solves a small resource leak that had us
333 not closing files until a connection was closed. In order to do
334 this, at the end of the core_output_filter, we loop through the
335 brigade and convert any data we have into a single HEAP bucket
336 that we know will survive clearing the request_rec.
337 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
340 *) Completely revamp configure so that it preserves the standard make
341 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
342 the configure additions to EXTRA_* variables. Also, allow the user
343 to specify NOTEST_* values for all of the above, which eliminates the
344 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
345 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
346 avoid pointless duplications. Fix the order in which flags are given
347 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
348 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
349 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
350 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
352 *) Get mod_tls to compile/work better on Windows. PR #7612
353 [Bernhard Schrenk <b.schrenk@improx.com>]
355 *) Fix shutdown/restart hangs in the threaded MPM.
356 [Jeff Trawick, Greg Ames, Ryan Bloom]
358 *) Removed the keptalive boolean from conn_rec because it is now only
359 used by a single routine and can be replaced by a local variable.
360 [Greg Stein, Ryan Bloom, Roy Fielding]
362 *) Patch prefork to put enough of the signal processing back in so that
363 signals are all handled properly now. The previous patch fixed the
364 deadlock race condition, but broke the user directed signal handling.
365 This fixes it to work the way it did before my previous prefork patch
366 (primarily, SIGTERM is now working).
368 *) Change how input filters decide how much data is returned to the
369 higher filter. We used to use a field in the conn_rec, with this
370 change, we use an argument to ap_get_brigade to determine how much
371 data is retrieved. [Ryan Bloom]
373 *) Fix seg fault at start-up introduced by Ryan's change to enable
374 modules to specify their own logging tags. mod_log_config
375 registers an optional function, ap_register_log_handler().
376 ap_register_log_handler() was being called by http_core before
377 the directive hash table was created. This patch creates the
378 directive hash table before ap_register_log_handler() is
379 registered as an optional function.
380 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
382 *) Add ap_set_int_slot() function
383 [John K. Sterling <sterling@covalent.net>]
385 *) Under certain circumstances, Apache did not supply the
386 right response headers when requiring authentication.
387 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
388 (This is a port of the change that went into Apache 1.3.19.)
390 *) Allow modules to specify their own logging tags. This basically
391 allows a module to tell mod_log_config that when %x is encountered
392 a specific function should be called. Currently, x can be any single
393 character. It may be more useful to make this a string at some point.
396 Changes with Apache 2.0.17
398 *) If a higher-level filter handles the the byterange aspects of a
399 request, then the byterange filter should not try to redo the
400 work. The most common case of this happening, is a byterange
401 request going through the proxy, and the origin server handles
402 the byterange request. The proxy should ignore it.
403 [Graham Leggett <minfrin@sharp.fm>]
405 *) Changed the threaded mpm to have child_main join to each of the
406 worker threads to make sure the kids are all gone before child_main
407 exits after a signal (cleanup from perform_idle_server_maintenance).
408 This is an extension of Ryans recent commit to make the child_main
411 *) Add more options to the ap_mpm_query function. This also allows MPMs to
412 report if their threads are dynamic or static. Finally, this also
413 implements a new API, ap_show_mpm, which returns the MPM that was
414 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
416 *) Do not install the binaries from the support directory twice.
417 [jun-ichiro hagino <itojun@iijlab.net>]
419 *) The ap_f* functions should flush data to the filter that is passed
420 in, not the the filter after the one passed in.
421 [Ryan Morgan <rmorgan@covalent.net>]
423 *) Make ab work again by changing its native types to apr types and formats.
424 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
426 *) Move the byterange filter and all of the supporting functions back
427 to the HTTP module. The byterange filter turned out to be very
428 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
430 *) Make clean, distclean, and extraclean consistently according to the
431 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
433 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
434 This may have been causing problems stopping processes in the threaded
437 *) Fix content-length in mod_negotiation to a long int representation.
440 *) Remove BindAddress from the default config file.
441 [giles@nemeton.com.au]
443 *) Allow module authors to add a module to their Apache build using
444 --with-module, without re-running buildconf. The syntax is:
445 --with-module=module_type:/path/to/module.c
446 The configure script will copy the module.c file to
447 modules/module_type, and it will be added to the relevant Makefiles.
448 currently, this only works for static modules. [Ryan Bloom]
450 *) Changes required to make prefork clean up idle children properly.
451 There was a window during which a starting worker deadlocks when
452 an idle cleanup arrives before it completes init. Apache then keeps
453 trying to cleanup the same deadlocked worker forever (until higher
454 pids come along, but it still will never reduce below the deadlocked
455 pid). Thus the number of children would not reduce to the correct
456 idle level. [Paul J. Reder]
458 Changes with Apache 2.0.16
460 *) Change the default installation directory to /usr/local/apache2,
461 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
463 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
466 *) Get MaxRequestsPerChild working with the Windows MPM.
469 *) Make generic hooks to work, with mod_generic_hook_import/export
470 experimental modules. [Ben Laurie, Will Rowe]
472 *) Fix segfaults for configuration file syntax errors such as
473 "<Directory>" followed by "</Directory" and
474 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
476 *) Cleanup the --enable-layout option of configure. This makes
477 us use a consistent location for the config.layout file, and it
478 makes configure more portable.
479 [jun-ichiro hagino <itojun@iijlab.net>]
481 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
482 csv/gnuplot format, rudimentary ssl support and various other tweaks
483 to make results more true to what is measured. The upshot of this it
484 turns out that 'ab' has often underreported the true performance of
485 apache. Often by a order of magnitude :-) See talk/paper of Sander
486 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
487 [Dirk-Willem van Gulik]
489 *) Clean up mod_cgid's temporary request pool. Besides fixing a
490 storage leak this ensures that some unnecessary pipes are closed.
493 *) Performance: Add quick_handler hook. This hook is called at the
494 very beginning of the request processing before location_walk,
495 translate_name, etc. This hook is useful for URI keyed content
496 caches like Mike Abbott's Quick Shortcut Cache.
499 *) top_module global variable renamed to ap_top_module [Perl]
501 *) Move ap_set_last_modified to the core. This is a potentially
502 controversial change, because this is kind of HTTP specific. However
503 many protocols should be able to take advantage of this kind of
504 information. I expect that headers will need one more layer of
505 indirection for multi-protocol work, but this is a small step in
506 the right direction. [Ryan Bloom]
508 *) Enable mod_status by default. This matches what Apache 1.3 does.
511 *) Add a ScriptSock directive to the default config file. This is
512 only enabled when mod_cgid is used.
513 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
515 Changes with Apache 2.0.15
517 *) Untangled the buildconf script and eliminated the need for build's
518 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
519 libtool muck that is now under srclib/apr/build. [Roy Fielding]
521 *) Win32: Don't accept more connections than we have worker threads
525 *) Fix bug in the Unix threaded.c MPM that allowed child processes
526 to fork() new child processes.
529 *) Fix a major security problem with double-reverse lookup checking.
530 Previously, a client connecting over IPv4 would not be matched
531 properly when the server had an IPv6 listening socket. PR #7407
532 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
534 *) Change the way the beos MPM handles polling to allow it to stop and
535 restart. Problem was the sockets being polled were being reset by
536 the select call, so once it had accepted a connection it was no
537 longer listening on the UDP socket we use for shutdown instructions.
538 APR needs to be altered, patch on it's way. [David Reid]
540 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
541 on error exit from ap_getline(). Some other code got upset because
542 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
544 *) Handle ap_discard_request_body() being called more than once.
545 [Greg Ames, Jeff Trawick]
547 *) Get rid of an inadvertent close of file descriptor 2 in
548 mod_mime_magic. [Greg Ames, Jeff Trawick]
550 *) Add a hook, create_request. This hook allows modules to modify
551 a request while it is being created. This hook is called for all
552 request_rec's, main request, sub request, and internal redirect.
553 When this hook is called, the the r->main, r->prev, r->next
554 pointers have been set, so modules can determine what kind of
555 request this is. [Ryan Bloom]
557 *) Cleanup the build process a bit more. The Apache configure
558 script no longer creates its own helper scripts, it just
560 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
562 *) Stop the forced downgrade of the connection to HTTP/1.0 for
563 proxy requests. [Graham Leggett]
565 *) Avoid using sscanf to determine the HTTP protocol number in
566 the common case because sscanf is a performance hog. From
567 Mike Abbot's Accelerating Apache patch number 6.
568 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
570 *) Fix a security exposure in mod_access. Previously when IPv6
571 listening sockets were used, allow/deny-from-IPv4-address rules
572 were not evaluated properly (PR #7407). Also, add the ability to
573 specify IPv6 address strings with optional prefix length on Allow
574 and Deny. [Jeff Trawick]
576 *) Enhance rotatelogs so that a UTC offset can be specified, and
577 the logfile name can be formatted using strftime(3). (Brought
578 forward from 1.3.) [Ken Coar]
580 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
581 DuplicateHandle on an IOCompletionPort (a practice which
582 MS "discourages"). The new model does not rely on associating
583 the completion port with the listening sockets, thus the
584 completion port can be completely managed within the child
585 process. A dedicated thread accepts connections off the network,
586 then calls PostQueuedCompletionStatus() to wake up worker
587 threads blocked on the completion port.
590 *) Bring forward the --suexec-umask option which allows the
591 builder to preset the umask for suexec processes. [Ken Coar]
593 *) Add a -V flag to suexec, which causes it to display the
594 compile-time settings with which it was built. (Only
595 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
597 *) Mod_include should always unset the content-length if the file is
598 going to be passed through send_parsed_content. There is no to
599 determine if the content will change before actually scanning the
600 entire content. It is far safer to just remove the C-L as long
601 as we are scanning it. [Ryan Bloom]
603 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
604 request and not Proxy-Authenticate.
605 [Graham Leggett <minfrin@sharp.fm>]
607 Changes with Apache 2.0.14
609 *) Fix content-length computation. We ONLY compute a content-length if
610 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
611 or we already have all the data. [Ryan Bloom]
613 *) Report unbounded containers in the config file. Previously, a typo
614 in the </container> directive could result in the rest of the config
615 file being silently ignored, with undesired defaults used.
618 *) Make the old_write filter use the ap_f* functions for the buffering.
621 *) Move more code from the http module into the core server. This
622 is core code, basically the default handler, the default input
623 and output filters, and all of the core configuration directives.
624 All of this code is required in order for the server to work, with or
625 without HTTP. The server is closer to working without the HTTP
626 module, although there is still more to do. [Ryan Bloom]
628 *) Fix a number of SGI compile warnings throughout the server. Fix some
629 bad parameters to apr_bucket_read(). Fix a bad statement in
630 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
631 consistently; we were mixing apr_time_t and time_t in invalid ways
632 before. In load_file(), call apr_dso_error() instead of
633 apr_strerror() so that we get a more specific string on some platforms.
634 PR #6980 [Jeff Trawick]
636 *) Allow modules to query the MPM about it's execution profile. This
637 query API can and should be extended in the future, but for now,
638 max_daemons, and threading or forking is a very good start.
639 [Jon Travis <jtravis@covalent.net>]
641 *) Modify mod_include to send blocks of data no larger than 9k.
642 Without this, mod_include will wait until the whole file is parsed,
643 or the first tag is found to send any data to the client.
644 [Paul J. Reder <rederpj@raleigh.ibm.com>]
646 *) Fix mod_info, so that <Directory> and <Location> directives are
647 not displayed twice when displaying the current configuration.
648 [Ryan Morgan <rmorgan@covalent.net>]
650 *) Add config directives to override DEFAULT_ERROR_MSG and
651 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
652 [Dan Rench <drench@xnet.com>]
654 *) Get mod_info building and loading on Win32. [William Rowe]
656 *) Begin to move protocol independant functions out of mod_http. The goal
657 is to have only functions that are HTTP specific in the http directory.
660 Changes with Apache 2.0.13
662 *) Don't assume that there will always be multiple calls to the byterange
663 filter. It is possible that we will need to do byteranges with only
664 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
666 *) Move the error_bucket definition from the http module to the
667 core server. Every protocol will need this ability, not just
670 Changes with Apache 2.0.12
672 *) Modify mod_file_cache to save pre-formatted strings for
673 content-length and last-modified headers for performance.
674 [Mike Abbot <mja@trudge.engr.sgi.com>]
676 *) Namespace protect IOBUFSIZ since it is exposed in the API.
677 [Jon Travis <jtravis@covalent.net>]
679 *) Use "Basic" authentication instead of "basic" in ab, as the spec
680 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
682 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
683 without ever filling it out. This fixes PR 7271.
684 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
685 Cliff Woolley <cliffwoolley@yahoo.com>]
687 *) Add a couple of GCC attribute tags to printf style functions.
688 [Jon Travis <jtravis@covalent.net>]
690 *) Add the correct language tag for interoperation with the Taiwanese
691 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
693 *) Migrate the perchild MPM to use the new apr signal child, and
694 APR thread functions. [Ryan Bloom]
696 *) Close one copy of the CGI's stdout before creating the new process.
697 The CGI will still have stdout, because we have already dup'ed it.
698 This keeps Apache from waiting forever to send the results of a CGI
699 process that has forked a long-lived child process.
700 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
702 *) Remove the rest of the pthreads functions from the threaded MPM.
703 This requires the APR support for a signal thread that was just
706 *) Make mod_dir use a fixup for sending a redirect to the browser.
707 Before this, we were using a handler, which doesn't make much
708 sense, because the handler wasn't generating any data, it would
709 either return a redirect error code, or DECLINED. This fits the
710 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
712 *) Make the threaded MPM use APR threads instead of pthreads.
715 *) Get mod_tls to the point where it actually appears to work in all cases.
718 *) implement --enable-modules and --enable-mods-shared for "all" and
721 *) Move the threaded MPM to use APR locks instead of pthread locks.
724 *) Rename mpmt_pthread to threaded. This is more in line with the
725 fact that mpmt_pthread shouldn't be using pthreads directly, and
726 it is a smaller name that doesn't tie into anything.
729 *) Rename the module structures so that the exported symbol matches
730 the file name, and it is easier to automate the installation
731 process (generating LoadModule directives from the module filenames).
734 *) Remove the coalesce filter. With the ap_f* functions, this filter
735 is no longer needed. [Ryan Bloom]
737 Changes with Apache 2.0.11
739 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
740 added feature of allowing a uid/gid per child process. If no
741 uid/gid is specified, then Perchild behaves exactly like dexter.
744 *) Get perchild building again. [Ryan Bloom]
746 *) Don't disable threads just because we are using the prefork MPM.
747 If somebody wants to compile without threads, they must now add
748 --disable-threads to the configure command line. [Ryan Bloom]
750 *) Begin to move the calls to update_child_status into common code, so
751 that each individual MPM does not need to update the scoreboard itself.
754 *) Allow mod_tls to compile under Unix boxes where openssl has been
755 installed to the system include files.
756 [Gomez Henri <new-httpd@slib.fr>]
758 *) Cleanup the mod_tls configure process. This should remove any need
759 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
760 configure doesn't check that yet. [Ryan Bloom]
762 *) Add a very early prototype of SSL support (in mod_tls.c). It is
763 vital that you read modules/tls/README before attempting to build
766 *) Fix a potential seg fault on all platforms. David Reid fixed this
767 on BEOS, but the problem could happen anywhere, so we don't want
768 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
770 *) Add new LogFormat directive, %D, to log time it takes to serve a
771 request in microseconds. [Bill Stoddard]
773 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
774 SetOutputFilter. This corresponds nicely with the other Set
775 directives, which operate on containers while the Add* directives
776 tend to work directly on extensions. [Ryan Bloom]
778 *) Cleanup the header handling a bit. This uses the apr_brigade_*
779 functions for the buffering so that we don't need to compute
780 the length of the headers before we actually create the header
783 *) Allow filters to buffer data using the ap_f* functions. These have
784 become macros that resolve directly to apr_brigade_*.
787 *) Get the Unix MPM's to do a graceful restart again. If we are going
788 to register a cleanup with ap_cleanup_scoreboard, then we have to
789 kill the cleanup with the same function, and that function can't be
792 *) Install all required header files. Without these, it was not
793 possible to compile some modules outside of the server.
796 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
797 forward from 1.3 to 2.0, we missed a single line, which broke regex
798 aliases. [Ryan Bloom]
800 *) We have a poor abstraction in the protocol. This is a temporary
801 hack to fix the bug, but it will need to be fixed for real. If
802 we find an error while sending out a custom error response, we back
803 up to the first non-OK request and send the data. Then, when we send
804 the EOS from finalize_request_protocol, we go to the last request,
805 to ensure that we aren't sending an EOS to a request that has already
806 received one. Because the data is sent on a different request than
807 the EOS, the error text never gets sent down the filter stack. This
808 fixes the problem by finding the last request, and sending the data
809 with that request. [Ryan Bloom]
811 *) Make the server status page show the correct restart time, and
812 thus the proper uptime. [Ryan Bloom]
814 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
815 should reduce the amount of duplicate code that is required to
816 create CGI processes.
817 [Paul J. Reder <rederpj@raleigh.ibm.com>]
819 *) ap_new_connection() closes the socket and returns NULL if a socket
820 call fails. Usually this is due to a connection which has been
821 reset. [Jeff Trawick]
823 *) Move the Apache version information out of httpd.h and into release.h.
824 This is in preparation for the first tag with the new tag and release
827 *) Begin restructuring scoreboard code to enable adding back in
828 the ability to use IPC other than shared memory.
829 Get mod_status working on Windows again. [Bill Stoddard]
831 *) Make mod_status work with 2.0. This will work for prefork,
832 mpmt_pthread, and dexter. [Ryan Bloom]
834 *) Correct a typo in httpd.conf.
835 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
837 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
839 *) Get the correct IP address if ServerName isn't set and we can't
840 find a fully-qualified domain name at startup.
841 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
843 *) Make mod_cgid work with SuExec. [Ryan Bloom]
845 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
846 'extra' stat's for user/group since they should never occur, and now
847 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
848 volumes. [William Rowe]
850 *) Adopt apr features to simplify mod_includes. This changes the
851 behavior of the USER_NAME variable, unknown uid's are now reported
852 as USER_NAME="<unknown>" rather than the old user#000 result.
853 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
855 *) Adopt apr features for simplifing mod_userdir, and accept the new
856 Win32/OS2 exceptions without hiccuping. [William Rowe]
858 *) Replace configure --with-optim option by using and saving the
859 environment variable OPTIM instead. This is needed because configure
860 options do not support multiple flags separated by spaces.
863 *) Fix some byterange handling. If we get a byte range that looks like
864 "-999999" where that is past the end of the file, we should return
865 a PARTIAL CONTENT status code, and return the whole file as one big
866 byterange. This matches the 1.3 handling now. [Ryan Bloom]
868 *) Make the error bucket a real meta-data bucket. This means that the
869 bucket length is 0, and a read returns NULL data. If one of these
870 buckets is passed down after the headers are sent, this data will
871 just be ignored. [Greg Stein]
873 *) The prefork MPM wasn't killing child processes correctly if a restart
874 signal was received while the process was serving a request. The child
875 process would become the equivalent of a second parent process. If
876 we break out of the accept loop, then we need to do die after cleaning
877 up after ourselves. [Ryan Bloom]
879 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
880 restarts. [Ryan Bloom]
882 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
883 the most optimal APR_FINFO_wanted bits. This spares Win32 from
884 performing very expensive owner, group and permission lookups
885 and allows the server to function until these apr_finfo_t fields
886 are implemented under Win32. [William Rowe]
888 *) Support for typedsafe optional functions - that is functions exported by
889 optional modules, which, therefore, may or may not be present, depending
890 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
891 for sample code. [Ben Laurie]
893 *) filters can now report an HTTP error to the server. This is done
894 by sending a brigade where the first bucket is an error_bucket.
895 This bucket is a simple bucket that stores an HTTP error and
896 a string. Currently the string is not used, but it may be needed
897 to output an error log. The http_header_filter will find this
898 bucket, and output the error text, and then return
899 AP_FILTER_ERROR, which informs the server that the error web page
900 has already been sent. [Ryan Bloom]
902 *) If we get an error, then we should remove all filters except for
903 those critical to serving a web page. This fixes a bug, where
904 error pages were going through the byterange filter, even though
905 that made no sense. [Ryan Bloom]
907 *) Relax the syntax checking of Host: headers in order to support
908 iDNS. PR#6635 [Tony Finch]
910 *) Cleanup the byterange filter to use the apr_brigade_partition
911 and apr_bucket_copy functions. This removes a lot of very messy
912 code, and hopefully makes this filter more stable.
915 *) Remove AddModule and ClearModuleList directives. Both of these
916 directives were used to ensure that modules could be enabled
917 in the correct order. That requirement is now gone, because
918 we use hooks to ensure that modules are in the correct order.
921 *) When SuExec is specified, we need to add it to the list of
922 targets to be built. If we don't, then any changes to the
923 configuration won't affect SuExec, unless 'make suexec' is
924 specifically run. [Ryan Bloom]
926 *) Cleaned out open_file from mod_file_cache, as apr now accepts
927 the APR_XTHREAD argument to open a file for consumption by
928 parallel threads on win32. [William Rowe]
930 *) Correct a bug in determining when we follow symlinks. The code
931 expected a stat -1 result, not an apr_status_t positive error.
932 Also check if the APR_FINFO_USER fields are valid before we
933 follow the link. [William Rowe]
935 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
936 mpm_common.c. These functions are only valid on some platforms,
937 so they should not be in the main-line code. [Ryan Bloom]
939 *) Remove ap_chdir_file(). This function is not thread-safe,
940 and nobody is currently using it. [Ryan Bloom]
942 *) Do not try to run make depend if there are no .c files in the
943 current directory, doing so makes `make depend` fail.
946 *) Update highperformance.conf to work with either prefork or
947 pthreads mpms. [Greg Ames]
949 *) Stop checking to see if this is a pipelined request if we know
950 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
951 This keeps us from making an extra read call when serving a 1.0
952 request. [Ryan Bloom and Greg Stein]
954 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
955 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
956 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
958 *) Fix the RFC number mentioned when complaining about a missing
959 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
961 *) Fix an endless loop in ab which occurred when ab was posting
962 and the server dropped the connection unexpectedly.
965 *) Fix a segfault while handling request bodies in ap_http_filter().
966 This problem has been seen with mod_dav usage as well as with
967 requests where the body was just being discarded. [Jeff Trawick]
969 *) Some adjustment on the handling and automatic setting (via
970 hints.m4) of various compilation flags (eg: CFLAGS). Also,
971 add the capability to specify flags (NOTEST_CFLAGS and
972 NOTEST_LDFLAGS) which are used to compile Apache, but
973 not used during the configuration process. Useful for
974 flags like "-Werror". [Jim Jagielski]
976 *) Stop using environment variables to force debug mode or
977 no detach. We now use the -D command line argument to
978 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
979 [Greg Stein, Ryan Bloom]
981 *) Change handlers to use hooks. [Ben Laurie]
983 *) Stop returning copies of filenames from both apr_file_t and
984 apr_dir_t. We pstrdup the filenames that we store in the
985 actual structures, so we don't need to pstrdup the strings again.
988 *) mod_cgi: Fix some problems where the wrong error value was being
989 traced. [Jeff Trawick]
991 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
994 *) Add generic hooks. [Ben Laurie]
996 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
998 *) Fix a segfault caused by mod_ext_filter when the external filter
999 program does not exist. [Jeff Trawick]
1001 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1002 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1003 was served through mod_charset_lite (or anything else that would
1004 create a transient bucket in this size range). ap_bucket_make_heap()
1005 silently failed (fixed), transient_setaside() discovered it, but
1006 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1008 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1009 is that some browsers send extra lines at the end of POST requests, and
1010 we don't want to delay sending data back to the user just because the
1011 browser isn't well behaved. [Ryan Bloom]
1013 *) Get SuEXEC working again. We can't send absolute paths to suExec
1014 because it refuses to execute those programs. SuEXEC also wasn't
1015 always recognizing configuration changes made using the autoconf
1018 *) Allow the buildconf process to find the config.m4 files in the correct
1019 order. Basically, we can now name config.m4 files as config\d\d.m4,
1020 and we will sort them correctly when inserting them into the build
1021 process. [Ryan Bloom]
1023 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1024 This also allows mod_cgid to use ap_os_create_priviledged_process,
1025 thus allowing for SuExec execution from mod_cgid. Currently, we do
1026 not support everything that standard SuExec supports, but at least
1027 it works minimally now. [Ryan Bloom]
1029 *) Allow SuExec to be configured from the ./configure command line.
1032 *) Update some of the docs in README and INSTALL to reflect some of
1033 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1035 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1036 need to call sendfile again. This gets us serving large files
1037 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1039 *) Get the support programs building cleanly again.
1040 [Cliff Woolley <cliffwoolley@yahoo.com>]
1042 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1043 current directory logic now backs up over bin/ to determine the
1044 server root from the Apache.exe path.
1046 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1047 loadable modules, dynamic libs are all named libfoo.dll, and the
1048 makefile.win populates the include, lib and libexec directories.
1050 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1051 Apache gets IPv6 listening sockets by default. Additionally, the
1052 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1053 numeric address strings (e.g., "Listen [fe80::1]:8080").
1056 *) Modify the install directory layout. Modules are now installed in
1057 modules/. Shared libraries should be installed in libraries/, but
1058 we don't have any of those on Unix yet. All install directories
1059 are modifyable at configure time. [Ryan Bloom]
1061 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1063 *) Get the functions in server/linked into the server, regardless of
1064 which modules linked into the server. This uses the same hack
1065 for Apache that we use for APR and apr-util to ensure all of the
1066 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1067 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1068 the scripts a bit easier.
1071 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1072 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1074 *) Get all of the auth modules to the point that they will install and
1075 be loadable into the server. Our new build/install mechanism expects
1076 that all modules will have a common name format. The auth modules
1077 didn't use that format, so we didn't install them properly.
1080 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1081 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1083 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1085 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1086 after the end of the response. [Ryan Bloom]
1088 *) Get byterange requests working with responses that do not have a
1089 content-length. Because of the way byterange requests work, we have to
1090 have all of the data before we can actually do the byterange, so we
1091 can compute the content-length in the byterange filter.
1094 *) Get exe CGI's working again on Windows.
1097 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1098 they keep track of whether or not their post config hook has been
1099 called before. Instead of a static variable (which is replaced when
1100 the DSO is loaded a second time), use userdata in the process pool.
1103 Changes with Apache 2.0a9
1105 *) Win32 now requires perl to complete the final install step for users
1106 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1107 and installs the conf, htdocs and htdocs/manual directories.
1110 *) Make mod_include use a hash table to associate directive tags with
1111 functions. This allows modules to implement their own SSI tags easily.
1112 The idea is simple enough, a module can insert it's own tag and function
1113 combination into a hash table provided by mod_include. While mod_include
1114 parses an SSI file, when it encounters a tag in the file, it does a
1115 hash lookup to find the function that implements that tag, and passes
1116 all of the relevant data to the function. That function is then
1117 responsible for processing the tag and handing the remaining data back
1118 to mod_include for further processing.
1119 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1121 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1122 fewer parameters: the local and remote socket addresses were removed
1123 from the parameter list because all required information is available
1124 via the APR socket. [Jeff Trawick]
1126 *) Distribution directory structure reorganized to reflect a
1127 normal source distribution with external install targets.
1130 *) The MPMs that need multiple segments of shared memory now create
1131 two apr_shmem_t variables, one for each shared memory allocation.
1132 the problem is that we can't determine how much memory will be required
1133 for shared memory allocations once we try to allocate more than one
1134 variable. The MM code automatically aligns the shared memory allocations,
1135 so we end up needing to pad the amount of shared memory we want based
1136 on how many variables will be allocated out of the shared memory segment.
1137 It is just easier to create a second apr_shmem_t variable, and two
1138 shmem memory blocks.
1141 *) Cleanup the export list a bit. This creates a single unified list of
1142 functions exported by APR. The export list is generated at configure
1143 time, and that list is then used to generate the exports.c file.
1144 Because of the way the export list is generated, we only export those
1145 functions that are valid on the platform we are building on.
1148 *) Enable logging the cookie with mod_log_config
1149 [Sander van Zoest <sander@covalent.net>]
1151 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1154 *) Added lib/aputil/ as a placeholder for utility functions which are not
1155 specific to the Apache HTTP Server (but do not make sense with APR).
1156 The first utility is "apu_dbm": a set of functions to work with DBM
1157 files. This first version can be compiled for SDBM or GDBM databases.
1160 *) Complete re-write of mod_include. This makes mod_include a filter that
1161 uses buckets directly. This has now served the FAQ correctly.
1162 [Paul Reder <rederpj@raleigh.ibm.com>]
1164 *) Allow modules to specify the first filter in a sub_request when
1165 making the sub_request. This keeps modules from having to change the
1166 output_filter immediately after creating the sub-request, and therefore
1167 skip the sub_req_output_filter. [Ryan Bloom]
1169 *) Update ab to accept URLs with IPv6 literal address strings (in the
1170 format described in RFC 2732), and to build Host header fields in
1171 the same format. This allows IPv6 literal address strings to be
1172 used with ab. This support has been tested against Apache 1.3 with
1173 the KAME patch, but Apache 2.0 does not yet work with this format
1174 of the Host header field. [Jeff Trawick]
1176 *) Accomodate an out-of-space condition in the piped logs and the
1177 rotatelogs.c code, and no longer churn log processes for this
1178 condition. [Victor J. Orlikowski]
1180 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1183 Changes with Apache 2.0a8
1185 *) Add a directive to mod_mime so that filters can be associated with
1189 *) Get multi-views working again. We were setting the path_info
1190 field incorrectly if we couldn't find the specified file.
1193 *) Fix 304 processing. The core should never try to send the headers
1194 down the filter stack. Always, just setup the table in the request
1195 record, and let the header filter convert it to data that is ready
1199 *) More fixes for the proxy. There are still bugs in the proxy code,
1200 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1204 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1207 *) APR: Add new apr_getopt_long function to handle long options.
1208 [B. W. Fitzpatrick <fitz@red-bean.com>]
1210 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1211 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1212 hostname resolution/address string parsing and building
1213 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1214 of one of the apr_sockaddr_t structures for a socket. Change
1215 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1217 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1218 I have proxied pages with it, cleanup will commence soon.
1221 *) Make the proxy work with filters. This isn't perfect, because we
1222 aren't dealing with the headers properly. [Ryan Bloom]
1224 *) Do not send a content-length iff the C-L is 0 and this is a head
1225 request. [Ryan Bloom]
1227 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1228 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1230 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1232 *) Get the default_handler to stop trying to deal with HEAD requests.
1233 The idea is to let the content-length filter compute the C-L before
1234 we try to send the data. If we can get the C-L correctly, then we
1235 should send it in the HEAD response.
1238 *) The Header filter can now determine if a body should be sent based
1239 on r->header_only. The general idea of this is that if we delay
1240 deciding to send the body, then we might be able to compute the
1241 content-length correctly, which will help caching proxies to cache
1242 our data better. Any handler that doesn't want to try to compute
1243 the content-length can just send an EOS bucket without data and
1244 everything will just work.
1247 *) Add the referer to the error log if one is available.
1248 [Markus Gyger <mgyger@itr.ch>]
1250 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1251 change, the root of the configuration tree has been exposed to modules
1253 [Ryan Morgan <rmorgan@covalent.net>]
1255 *) Get the core_output_filter to use the bucket interface directly.
1256 This keeps us from calling the content-length filter multiple times
1257 for a simple static request.
1260 *) We are sending the content-type correctly now.
1261 [Ryan Bloom and Will Rowe]
1263 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1264 a bogus bytes-sent value when the only thing being sent was trailers
1265 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1267 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1268 hints file to determine which platforms define
1269 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1272 *) APR: add apr_get_home_directory() [Jeff Trawick]
1274 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1276 *) Not all platforms have INADDR_NONE defined by default. Apache
1277 used to make this check and define INADDR_NONE if appropriate,
1278 but APR needs the check too, and I suspect other applications will
1279 as well. APR now defines APR_INADDR_NONE, which is always a valid
1280 value on all platforms.
1281 [Branko Èibej <brane@xbc.nu>]
1283 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1284 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1286 *) Relax the syntax checking of Host: headers in order to support
1287 iDNS. PR#6635 [Tony Finch]
1289 *) When reading from file buckets we convert to an MMAP if it makes
1290 sense. This also simplifies the default handler because the
1291 default handler no longer needs to try to create MMAPs.
1294 *) BUFF has been removed from the main server. The BUFF code will remain
1295 in the code until it has been purged from the proxy module as well.
1298 *) Byteranges have been completely re-written to be a filter. This
1299 has been tested, and I believe it is working correctly, but it could
1300 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1301 the output from 1.3, the only difference being that 1.3 includes
1302 a content-length in the response, and this does not.
1305 *) APR read/write functions and bucket read functions now operate
1306 on unsigned integers, instead of signed ones. It doesn't make
1307 any sense to use signed ints, because we return the error codes,
1308 so if we have an error we should report 0 bytes read or written.
1311 *) Always compute the content length, whether it is sent or not.
1312 The reason for this, is that it allows us to correctly report
1313 the bytes_sent when logging the request. This also simplifies
1314 content-length filter a bit, and fixes the actual byte-reporing
1315 code in mod_log_config.c
1318 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1319 it says, because it was only used by EOS and FLUSH buckets. Since
1320 neither of those are required at the end of a brigade, this was
1321 really signifying FLUSH_THE_DATA, but that can be determined better
1322 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1323 buckets now return a length of 0, which is actually the amount of data
1324 read, so they make more sense.
1327 *) Allow the core_output_filter to save some data past the end of a
1328 request. If we get an EOS bucket, we only send the data if it
1329 makes sense to send it. This allows us to pipeline request
1330 responses. As a part of this, we also need to allocate mmap
1331 buckets out of the connection pool, not the request pool. This
1332 allows the mmap to outlive the request.
1335 *) Make blocking and non-blocking bucket reads work correctly for
1336 sockets and pipes. These are the only bucket types that should
1337 have non-blocking reads, because the other bucket types should
1338 ALWAYS be able to return something immediately.
1341 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1342 server, but use Ctrl+Break to initiate a graceful restart
1343 instead of duplicating behavior. [John Sterling]
1345 *) Patch mod_autoindex to set the Last-Modified header based on
1346 the directory's mtime, and add the ETag header. [William Rowe]
1348 *) Merge the 1.3 patch to add support for logging query string in
1349 such a way that "%m %U%q %H" is the same as "%r".
1352 *) Port three log methods from mod_log_config 1.3 to 2.0:
1353 CLF compliant '-' byte count, method and protocol.
1356 *) Add a new LogFormat directive, %c, that will log connection
1357 status at the end of the response as follows:
1358 'X' - connection aborted before the response completed.
1359 '+' - connection may be kept-alive by the server.
1360 '-' - connection will be closed by the server.
1363 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1364 Unicode file names and paths for Win32, and tag the Content-Type
1365 from mod_autoindex to reflect that charset if the the feature
1366 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1368 *) Compute the content length (and add appropriate header field) for
1369 the response when no content length is available and we can't use
1370 chunked encoding. [Jeff Trawick]
1372 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1373 so that content input filters get dechunked data when using
1374 the default handler. Also removed REQUEST_CHUNKED_PASS.
1377 *) Add mod_ext_filter as an experimental module. This module allows
1378 the administrator to use external programs as filters. Currently,
1379 only filtering of output is supported. [Jeff Trawick]
1381 *) Most Apache functions work on EBCDIC machines again, as protocol
1382 data is now translated (again). [Jeff Trawick]
1384 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
1385 the EBCDIC support. They are noops on ASCII machines, so this
1386 type of translation doesn't have to be surrounded by #ifdef
1387 CHARSET_EBCDIC. [Jeff Trawick]
1389 *) Fix mod_include. tag commands work again, and the server will
1390 send the FAQ again. This also allows mod_include to set aside
1391 buckets that include partial buckets.
1392 [Ryan Bloom and David Reid]
1394 *) Add suexec support back. [Manoj Kasichainula]
1396 *) Lingering close now uses the socket directly instead of using
1397 BUFF. This has been tested, but since all we can tell is that it
1398 doesn't fail, this needs to be really hacked on.
1401 *) Allow filters to modify headers and have those headers be sent to
1402 the client. The idea is that we have an http_header filter that
1403 actually sends the headers to the network. This removes the need
1404 for the BUFF to send headers.
1407 *) Charset translation: mod_charset_lite handles translation of
1408 request bodies. Get rid of the xlate version of ap_md5_digest()
1409 since we don't compute digests of filtered (e.g., translated)
1410 response bodies this way anymore. (Note that we don't do it at
1411 all at the present; somebody needs to write a filter to do so.)
1414 *) Input filters and ap_get_brigade() now have a input mode parameter
1415 (blocking, non-blocking, peek) instead of a length parameter.
1418 *) Update the mime.types file to the registered media types as
1419 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
1422 *) Namespace protect some macros declared in ap_config.h
1425 *) Support HTTP header line folding with input filtering.
1428 *) Mod_include works again. This should still be re-written, but at
1429 least now we can serve an SHTML page again.
1432 *) Begin to remove BUFF from the core. Currently, we keep a pointer
1433 to both the BUFF and the socket in the conn_rec. Functions that
1434 want to use the BUFF can, functions that want to use the socket,
1435 can. They point to the same place.
1438 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
1439 [Tomas "Ögren" <stric@ing.umu.se>]
1441 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
1442 associated pool goes away. (APR pipes on OS/2 were already had this
1443 logic.) This resolvs a fatal file descriptor leak with CGIs.
1446 *) The final line of the config file was not being read if there was
1447 no \n at the end of it. This was caused by apr_fgets returning
1448 APR_EOF even though we had read valid data. This is solved by
1449 making cfg_getline check the buff that was returned from apr_fgets.
1450 If apr_fgets return APR_EOF, but there was data in the buf, then we
1451 return the buf, otherwise we return NULL.
1454 *) Piped logs work again in the 2.0 series.
1457 *) Restore functionality broken by the mod_rewrite security fix:
1458 rewrite map lookup keys and default values are now expanded
1459 so that the lookup can depend on the requested URI etc.
1460 PR #6671 [Tony Finch]
1462 *) Tighten up the syntax checking of Host: headers to fix a
1463 security bug in some mass virtual hosting configurations
1464 that can allow a remote attacker to retrieve some files
1465 on the system that should be inaccessible. [Tony Finch]
1467 *) Add a pool bucket type. This bucket is used for data allocated out
1468 of a pool. If the pool is cleaned before the bucket is destroyed, then
1469 the data is converted to a heap bucket, allowing it to survive the
1473 *) Add a flush bucket. This allows modules to signal that the filters
1474 should all flush whatever data they currently have. There is no way
1475 to actually force them to do this, so if a filter ignores this bucket,
1476 that's life, but at least we can try with this.
1479 *) Add an output filter for sub-requests. This filter just strips the
1480 EOS bucket so that we don't confuse the main request's core output
1481 filter by sending multiple EOS buckets. This change also makes sub
1482 requests start to send EOS buckets when they are finished.
1485 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
1486 makes ap_bucket_destroy a return void, which is okay because it
1487 used to always return APR_SUCCESS, and nobody ever checked its
1488 return value anyway.
1489 [Cliff Woolley <cliffwoolley@yahoo.com>]
1491 *) Remove the index into the bucket-type table from the buckets
1492 structure. This has now been replaced with a pointer to the
1493 bucket_type. Also add some macros to test the bucket-type.
1496 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
1497 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
1498 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
1499 All _VAR_ flavors changes to _DATA to be absolutely clear.
1502 *) Add support for /, //, //servername and //server/sharename
1503 parsing of <Directory> blocks under Win32 and OS2.
1504 [Tim Costello, William Rowe, Brian Harvard]
1506 *) Remove the function pointers from the ap_bucket type. They have been
1507 replaced with a global table. Modules are allowed to register bucket
1508 types and use then use those buckets.
1511 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
1512 once we finish writing the request body to the cgi child process;
1513 otherwise, the client doesn't hit EOF on stdin. Small request bodies
1514 worked without this change (for reasons I don't understand), but large
1515 ones didn't. [Jeff Trawick]
1517 *) Remove file bucket specific information from the ap_bucket type.
1518 This has been moved to a file_bucket specific type that hangs off
1519 the data pointer in the ap_bucket type.
1522 *) Input filtering now has a third argument. This is the amount of data
1523 to read from lower filters. This argument can be -1, 0, or a positive
1524 number. -1 means give me all the data you have, I'll deal with it and
1525 let you know if I need more. 0 means give me one line and one line
1526 only. A positive number means I want no more than this much data.
1528 Currently, only 0 and a positive number are implemented. This allows
1529 us to remove the remaining field from the conn_rec structure, which
1533 *) Big cleanup of the input filtering. The goal is that http_filter
1534 understands two conditions, headers and body. It knows where it is
1535 based on c->remaining. If c->remaining is 0, then we are in headers,
1536 and http_filter returns a line at a time. If it is not 0, then we are
1537 in body, and http_filter returns raw data, but only up to c->remaining
1538 bytes. It can return less, but never more.
1539 [Greg Ames, Ryan Bloom, Jeff Trawick]
1541 *) mod_cgi: Write all of the request body to the child, not just what
1542 the kernel would accept on the first write. [Jeff Trawick]
1544 *) Back out the change that moved the brigade from the core_output_filters
1545 ctx to the conn_rec. Since all requests over a given connection
1546 go through the same core_output_filter, the ctx pointer has the
1550 *) Fix another bug in the send_the_file() read/write loop. A partial
1551 send by apr_send would cause unsent data in the read buffer to
1552 get clobbered. Complete making send_the_file handle partial
1553 writes to the network.
1556 *) Fix a couple of type fixes to allow compilation on AIX again
1557 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
1559 *) Fix bug in send_the_file() which causes offset to be ignored
1560 if there are no headers to send.
1563 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
1564 filter. Useful for supporting Windows 9* with a binary
1565 compiled on Windows NT.
1568 Changes with Apache 2.0a7
1570 *) Reimplement core_output_filter to buffer/save bucket brigades
1571 across multiple calls to the core_filter. The brigade will be
1572 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
1573 thresholds are hit or the EOS bucket is received.
1576 *) Create experimental filter (buffer_filter) that coalesces bytes
1577 into one large buffer before invoking the next filter in the
1578 chain. This filter is particularly useful with the current
1579 implementation of mod_autoindex when it inserted above the
1580 chunk_filter. mod_autoindex generates a lot of brigades that
1581 containing buckets holding just a few bytes each. The
1582 buffer_filter coalesces these buckets into a single large bucket.
1585 *) Add apr_sendfile() support into the core_output_filter.
1588 *) Add apr_sendv() support into the core_output_filter.
1591 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
1592 [Mike Abbott <mja@sgi.com>]
1594 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
1595 make much sense, because Apache uses buckets instead of BUFFs now.
1598 *) send_the_file now falls back to a read/write loop on platforms that
1599 do not have sendfile.
1600 [Ryan Bloom and Brian Havard]
1602 *) Install apachectl correctly, and substitute the proper values so
1603 that it works again. [Ryan Bloom]
1605 *) Better(??) handle platforms that lack sendfile().
1608 *) APR now has UUID generation/formatting/parsing support.
1611 *) Begin the http_filter. This is an input filter that understands
1612 the absolute basic amount required to parse an HTTP Request. The
1613 goal is to be able to split headers from request body before passing
1614 the data back to the other filters.
1617 *) Bring forward from 1.3.13 the config directory implementation
1620 *) install apxs if it is created
1623 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
1624 conversions. [William Rowe]
1626 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
1627 ap_add_output_filter(). [Jeff Trawick]
1629 *) Multiple build and configuration fixes
1632 -add datadir and localstatedir substitutions
1634 -fix logfilename misspelling
1635 -fix evaluation of installation dir variables and
1636 -replace $foobar by $(foobar) to be usefull in the makefile
1640 -add rules for cross-compiling in rules.mk. Okay, rule to check for
1641 $CC_FOR_BUILD is still missing
1642 -use CHECK_TOOL instead of CHECK_PROG for ranlib
1643 -add missing "AR=@AR@" to severaly Makefile.in's
1644 -cache result for "struct rlimit"
1645 -compile all helper programs with native and cross compiler
1646 and use the native version to generate header file
1647 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1649 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
1651 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1653 *) Fix a bug where a client which only sends \n to delimit header
1654 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
1655 message. Start working on ebcdic co-existance with input
1657 [William Rowe, Greg Ames]
1659 *) If mod_so is enabled in the server always create libexec, even
1660 if there are no modules installed in this directory. This is a
1661 requirement for APXS to work correctly.
1664 *) Connection oriented output filters are now stored in the
1665 conn_rec instead of the request_rec. This allows us to add the
1666 output filter in the pre-connection phase instead of the
1667 post_read_request phase, which keeps us from trying to write an
1668 error page before we have a filter to write to the network.
1669 [Ryan Bloom, Jeff Trawick, and Greg Ames]
1671 *) Cleaning up an mmap bucket no longer deletes the mmap. An
1672 mmap can be used across multiple buckets (default_handler with
1673 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
1674 the mmap itself can't be associated with the bucket.
1677 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1680 *) Radical surgery to improve mod_isapi support under Win32.
1681 Includes a number of newer ServerSupportFunction calls, support
1682 for ReadClient (in order to retrieve POSTs greater than 48KB),
1683 and general bug fixes to more reliably load ISAPI .dll's and
1684 prevent leaking handle resources. Note: There are still
1685 discrepancies between IIS's and Apache's ServerVariables, and
1686 async calls are still not supported. Additional warnings are
1687 logged to facilitate debugging of unsupported ISAPI calls.
1690 *) Add input filtering to Apache. The basic idea for the input
1691 filters is the same as the ideas for output filters. The biggest
1692 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1693 should be called, and the order of execution for the filter itself is
1694 different. When writing an output filter, a brigade is passed in,
1695 and filters operate directly on that brigade, when done, they call
1696 ap_pass_brigade. Input filters are the exact opposite. Because input
1697 is not a push operation, filters first call ap_get_brigade. When this
1698 function returns, the input filter will be left with a valid brigade.
1699 The input filter should then operate on the brigade, and return.
1702 *) Fix building on BSD/OS using its native make. The build system
1703 falls back to the BSD .include directive on that host platform.
1706 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1707 SHA1 and plaintext password encodings. Make feature tests a
1708 bit more flexible. [William Rowe]
1710 *) Charset translation: mod_charset_lite handles output content
1711 translation in a filter. mod_charset_lite no longer ignores
1712 subrequests. A bunch of cruft related to BUFF's support for
1713 translating request and response bodies was removed.
1716 *) Move the addition of the CORE filter to the post_read_request
1717 hook in http_core.c. This removes the need to add the filter in
1718 multiple places and allows for an SSL module to be added much
1719 simpler. [Ryan Bloom]
1721 *) Fix a security problem that affects certain configurations of
1722 mod_rewrite. If the result of a RewriteRule is a filename that
1723 contains expansion specifiers, especially regexp backreferences
1724 $0..$9 and %0..%9, then it may be possible for an attacker to
1725 access any file on the web server. [Tony Finch]
1727 *) Fix a bug where errors that are detected during early request parsing
1728 don't produce visible HTTP error messages at the browser, because
1729 the core_filter wasn't present. [Greg Ames]
1731 *) Provide apr_socklen_t as a portability aid.
1732 [Victor J. Orlikowski]
1734 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1735 as well as a comment arg to the add, adduser and update cmds.
1736 update allows the user to clear or preserve pw/groups/comment.
1737 Fixed a bug in dbmmanage that prevented the check option from
1738 parsing a password followed by :group... text. Corrected the
1739 seed calcualation for Win32 systems, and added -lsdbm support.
1742 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1745 *) Avoid a segfault when parsing .htaccess files. An
1746 uninitialized tree pointer was passed to ap_build_config().
1749 *) Change the way that inet_addr & inet_network are checked for
1750 in APR's configure process to allow BeOS BONE to correctly
1751 find them. With this change BeOS BONE now builds from source
1752 with no problems. [David Reid]
1754 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1755 the end of the parameters to execve() was stored in the wrong
1756 location, overlaying the storage beyond the newargs[] array and
1757 also passing uninitialized storage to execve(), which would
1758 sometimes fail with EFAULT. [Jeff Trawick]
1760 *) Fix a bug parsing configuration file containers. With a sequence
1761 like this in the config file
1763 <IfModule mod_kilroy.c>
1766 <IfModule mod_lovejoy.c>
1771 the second container would be terminated at the blank line due to
1772 sediment in the buffer from reading the prior </IfModule> and an
1773 error message would be generated for the real </IfModule> for the
1774 second container. Also due to this problem, any two characters
1775 could be used for "</" in the close of a container.
1778 *) ap_add_filter prototype changed to remove the ctx pointer. The
1779 pointer still remains in the filter structure, but it can not be
1780 a part of the ap_add_filter prototype. The reason is that when
1781 the core uses AddFilter to add a filter to the stack it doesn't
1782 know how to allocate the ctx pointer, or even how much memory should
1783 be allocated. The filters will have to be responsible for allocating
1784 the ctx memory when they need it.
1787 *) Add an AddFilter directive. This directive takes a list of filters
1788 that should be activated for the requested resource.
1791 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1792 some other platforms). [Jeff Trawick]
1794 *) Modify mod_include to be a filter. Currently, it has only been tested
1795 on actual files, but it should work for CGI scripts too.
1798 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1799 writes. apr_flush() for Unix: handle interrupted writes.
1802 *) NameVirtualHost can now take "*" as an argument instead of
1803 an IP address. This allows you to create a purely name-based
1804 virtual hosting server that does not have any IP addresses in
1805 the configuration file and which ignores the local address
1806 of any connections. PR #5595, PR #4455 [Tony Finch]
1808 *) Fix some compile warnings in mod_mmap_static.c
1809 [Mike Abbott <mja@sgi.com>]
1811 *) Fix chunking problem with CGI scripts. The general problem was that
1812 the CGI modules were adding an EOS bucket and then the core added an
1813 EOS bucket. The chunking filter finalizes the chunked response when it
1814 encounters an EOS bucket. Because two EOS buckets were sent, we
1815 finalized the response twice. The fix is to make sure we only send one
1816 EOS, by utilizing a flag in the request_rec.
1819 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1820 and Win32. Previously, the first read from an apr_file_t set up via
1821 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1823 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1824 bucket, instead of using BUFF's and ap_r*.
1827 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1828 [Mike Abbott <mja@sgi.com>]
1830 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1831 code to use APR file's directly instead of going through BUFFs.
1834 *) Fix compile break on some platforms for mod_mime_magic.c
1835 [John K. Sterling <sterling@covalent.net>]
1837 *) Fix merging of AddDefaultCharset directive.
1838 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1840 *) Minor revamp of the rlimit sections of code. We now test
1841 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1842 is now "available" even if the platform doesn't support
1843 the rlimit family (it's just a noop though). [Jim Jagielski]
1845 *) Migrate the pre-selection of which MPM to use for specific
1846 platforms to hints.m4, which contains (or should contain)
1847 all platform specific "hints". [Jim Jagielski]
1849 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1852 *) Add tables with non-string/binary values to APR.
1855 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1858 *) Update PCRE to version 3.2. [Ryan Bloom]
1860 *) Change the way buckets' destroy functions are called so that
1861 they can be more directly used when changing the type of a
1862 bucket in place. [Tony Finch]
1864 *) Add generic support for reference-counting the resources used by
1865 buckets, and alter the HEAP and MMAP buckets to use it. Change
1866 the way buckets are initialised to support changing the type of
1867 buckets in place, and use it when setting aside TRANSIENT buckets.
1868 Change the implementation of TRANSIENT buckets so that it can be
1869 mostly shared with IMMORTAL buckets, which are now implemented.
1872 Changes with Apache 2.0a6
1874 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1876 *) Add a chunking filter to Apache. This brings us one step closer
1877 to removing BUFF. [Ryan Bloom]
1879 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1880 added to the stack is the last filter to be called. [Ryan Bloom]
1882 *) Apache 2.0 has been completely documented using Scandoc. The
1883 docs can be generated by running 'make docs'. [Ryan Bloom]
1885 *) Add filtered I/O to Apache. This is based on bucket brigades,
1886 Currently the buckets still use BUFF under the covers, but that
1887 should change quickly. The only currently written filter is the
1888 core filter which just calls ap_bwrite. [The Apache Group]
1890 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
1891 built with thread support. [Jeff Trawick]
1893 *) Abort configuration if --with-layout was specified and there's
1894 no layout definition file. [Ken Coar]
1896 *) Add support for '--with-port=n' option to configure. [Ken Coar]
1898 *) Add support for extension methods for the Allow response header
1899 field, and an API routine for accessing r->allowed and the
1900 list of extension methods in a unified manner. [Ken Coar]
1902 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
1903 [Rob Simonson <simo@us.ibm.com>]
1905 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
1906 APACHE_XLATE builds. [Jeff Trawick]
1908 *) A configuration file parsing problem was fixed. When the
1909 configuration file started with an IfModule/IfDefine container,
1910 only the last statement in the container would be retained.
1913 Changes with Apache 2.0a5
1915 *) Perchild is serving pages after passing them to different child
1916 processes. There are still a lot of bugs, but this does work. I
1917 have made requests against the same installation of Apache, and had
1918 different servers use different user IDs to serve the responses.
1919 This change moves to using socketpair instead of an AF_UNIX socket.
1922 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
1923 It can't seem to pass between child processes yet, but I think we
1924 are closer now than before. This moves us back to using Unix
1925 Domain Sockets. [Ryan Bloom]
1927 *) libapr functions and types renamed with apr_ prefix.
1928 #include "apr_compat.h" for 1.3.x backwards compat
1931 *) Fix problems with APR sockaddr handling on Win32. It didn't always
1932 return the right information on the local socket address.
1933 [Gregory Nicholls <gnicholls@level8.com>]
1935 *) ap_recv() on Win32: Set bytes-read to 0 on error.
1936 [Gregory Nicholls <gnicholls@level8.com>]
1938 *) Add an option to not detach from the controlling terminal without
1939 going into single process mode. This allows for much easier
1940 debugging of the process startup code. [Ryan Bloom]
1942 *) ab: don't use perror() to report the failure of an APR function.
1945 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
1946 scoreboard on graceful restarts.
1949 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
1950 An invalid ap_proc_t was passed to ap_create_process().
1953 *) Allow modules to register filters. Those filters are still
1954 never called, but this is a step in the right direction.
1955 [Ryan Bloom and Greg Stein]
1957 *) Register the mod_cgid daemon process for cleanup so that it is
1958 killed at termination if it does not die when the parent gets
1959 SIGTERM. This change is to fix occasional problems where the
1960 process stays around. Bugs in similar logic in mod_rewrite and
1961 mod_include were also fixed. [Jeff Trawick]
1963 *) Fix a bug in the time handling. Basically, we were imploding a time
1964 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
1965 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
1966 uses those two fields to adjust the time value. Because of the HTTP
1967 spec, both of those values can be zero'ed out safely. This fixes
1968 the bug correctly. [Ryan Bloom]
1970 *) Fix a couple of place in the Windows code where the wrong error
1971 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
1973 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
1975 *) Added the APR_EOL_STR macro for platform dependent differences in
1976 logfiles and other raw text (such as all APR files). Fixes logfiles
1977 not terminated with cr/lf sequences in Win32. [William Rowe]
1979 *) Move all strings functions in APR to src/lib/apr/strings and create
1980 apr_strings.h for the prototypes. [Ryan Bloom]
1982 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
1983 to repeat the syscall until we stop getting EINTR. I noticed a
1984 related problem at termination (SIGTERM) on FreeBSD when using
1985 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
1986 implementation work properly with child init. Previously, ap_lock()
1987 was essentially a no-op because all children were using different
1988 locks and thus nobody ever blocked. [Jeff Trawick]
1990 *) The htdocs/ tree has been moved out of the CVS source tree into
1991 a separate area for easier development. This has NO EFFECT on
1992 end-users or Apache installations. [Ken Coar]
1994 *) Integrate the mod_dav module for WebDAV protocol handling. This
1995 adds the dav and dav_fs modules, the SDBM library, and additional
1996 XML handling utilities. [Greg Stein]
1998 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2001 *) Update the lib/expat-lite/ library (bring forward changes from
2002 the Apache 1.3 repository). [Greg Stein]
2004 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2005 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2007 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2008 machines where sendfile is detected, but nobody has written ap_sendfile.
2009 [Dave Hill <ddhill@zk3.dec.com>]
2011 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2013 *) ab would start up more connections than needed, then quit when the
2014 desired number were finished. Also fixed a logic error involving
2015 ab keepalives. [Victor J. Orlikowski]
2017 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2018 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2019 timeouts (i.e, if a timeout was specified, the pipe reverted to
2020 a full blocking pipe). Now the behaviour is more in line with
2021 Unix non-blocking pipes.
2024 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2025 cache open file handles along with accept socket reuse enables
2026 Apache 2.0 to serve non-keepalive requests for static files at
2027 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2028 and Apache 2.0 will serve almost 1200 rps on my system).
2031 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2032 supports two config directives, mmapfile (same behavious as
2033 mod_mmap_static) and cachefile. Use the cachefile directive
2034 to cache open file handles. This directive only works on systems
2035 that have implemented the ap_sendfile API. cachefile works today
2036 on Windows NT, but has not been tested on any flavors of Unix.
2039 *) Cleanup the configuration. With the last few changes the
2040 configuration process automatically:
2041 inherits information about how to build from APR. Allowing
2042 APR to inform Apache that it should or should not use -ldl
2044 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2045 based on the threading model
2047 Apache calls APR's configure process before finishing it's
2048 configuration processing, allowing for more information flow
2053 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2054 with non-zero argument makes the socket non-blocking. BeOS and
2055 OS/2 already worked this way. [Jeff Trawick]
2057 *) ap_close() now calls ap_flush() for buffered files, so write
2058 operations work a whole lot better on buffered files.
2061 *) Fix error messages issued from MPMs which explain where to change
2062 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2065 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2066 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2067 now the way that the blocking state of a pipe is manipulated.
2068 ap_block_pipe() is gone. [Jeff Trawick]
2070 *) Correct the problem where the only local host name that the IP stack
2071 can discover are 'undotted' private names. If no fully qualified
2072 domain name can be identified, the default ServerName will be set to
2073 the machine's IP address string. A warning is always provided if the
2074 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2076 *) Repair problems with config file processing which caused segfault
2077 at init when virtual hosts were defined and which caused ServerName to
2078 be ignored when there was no valid DNS setup. [Jeff Trawick]
2080 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2082 *) Add ap_sendfile implementation for AIX
2083 [Victor J. Orlikowski]
2085 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2086 apr_network_io.h, and apr_thread_proc.h.
2087 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2089 *) Bring the allocation and pool debugging code back into a working
2090 state. This will need to be tested as so far it's only been used on
2093 *) Change configuration command setup to be properly typesafe when in
2094 maintainer mode. Note that this requires a compiler that can initialise
2095 unions. [Ben Laurie]
2097 *) Turn on buffering for config file reads. Part of this was to
2098 repair buffered I/O support in Unix and implement buffered
2099 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2101 *) Win32: Fix problem where UTC offset was not being set correctly
2102 in the access log. Problem reported on news group by Jerry Baker.
2105 *) Fix segfault when reporting this type of syntax error:
2106 "</container> without matching <container> section", where
2107 container is VirtualHost or Directory or whatever.
2110 *) Prevent the source code for CGIs from being revealed when using
2111 mod_vhost_alias and the CGI directory is under the document root
2112 and a user makes a request like http://www.example.com//cgi-bin/cgi
2113 as reported in <news:960999105.344321@ernani.logica.co.uk>
2116 *) Add support for the new Beos NetwOrking Environment (BONE)
2119 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2120 final input char is incomplete; ap_bwrite_xlate() now handles
2121 incomplete final input chars. [Jeff Trawick]
2123 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2124 that a bhalfduplex call occurs before logging or else DNS and
2125 such can delay the last packet of the response. [Dean Gaudet]
2127 *) Some syscall reduction in APR on unix -- don't seek when setting
2128 up an mmap; and don't fcntl() more than once per socket.
2131 *) When mod_cgid is started as root, the cgi daemon now switches
2132 to the configured User/Group (like other httpd processes)
2133 instead of continuing as root. [Jeff Trawick]
2135 *) The prefork MPM now uses an APR lock for the accept() mutex.
2136 It has not been getting a lock at all recently. httpd -V now
2137 displays APR's selection of the lock mechanism instead of the
2138 symbols previously respected by prefork. [Jeff Trawick]
2140 *) Change the mmap() feature test to check only for existence.
2141 The previous check required features not used by Apache.
2144 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2145 sometimes mangled. The len parm to accept() was not
2146 initialized, leading sometimes to an endless loop of failed
2147 accept() calls on OS/390 and anywhere else that failed the call
2148 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2149 instead of declaring it ourselves to fix a compilation problem
2150 on Solaris. [Jeff Trawick]
2152 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2154 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2156 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2158 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2159 initialization if ALLOC_DEBUG is defined; no known symptom
2160 otherwise. [Jeff Trawick]
2162 *) Fix typo in configure script when checking for mod_so. bash
2163 doesn't seem to have a problem but /bin/sh on Solaris does.
2164 Symptom: "./configure: test: unknown operator =="
2167 *) Rebind the Win32 NT and 9x services control into the MPM.
2168 All console, WinNT SCM and Win9x pseudo-service control code is
2169 now wrapped within the WinNT MPM.
2172 *) Make a copy of getenv("PATH") before storing for later use. Some
2173 getenv() implementations use the same storage for successive calls.
2174 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2176 *) Server Tokens work in 2.0 again. This also propogates the change
2177 to allow just the product name in the server string using
2181 Changes with Apache 2.0a4
2183 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2184 won't need to call it. [Greg Ames, Jeff Trawick]
2186 *) Move pre_config hook call to between configuration read and config
2187 tree walk. This allows all modules to implement pre_config hooks
2188 and know that they will be called at an appropriate time.
2191 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2194 *) Add pre-config hooks back to all modules.
2197 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2198 ContentDigest enabled and we can't/don't mmap the file.
2201 *) We now report the correct line number for syntax errors in config
2202 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2204 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2205 related bugs, and changed shmem/locking to use apr API. Shared-mem
2206 is currently disabled, however, because of problems with graceful
2207 restarts. [Ronald Tschalär]
2209 *) Fix corruption of IFS variable in --with-module= handling.
2210 Depending on the user's shell or customization thereof, there
2211 would be errors generating ap_config_auto.h later in the configure
2212 procedure. [Jeff Trawick]
2214 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2215 isn't used (as in 1.3), except that on Unix it is now logged via
2216 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2217 to the error log. [Greg Ames, Jeff Trawick]
2219 *) Add '-D' argument processing for run time configuration defines.
2222 *) Organize http_main.c as independent code, such that no code or
2223 global data is exported from it. WIN32 will dynamically link it
2224 to the server core, so this will prevent mutual dependency.
2227 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2228 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2231 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2232 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2234 *) Add mod_charset_lite for configuring character set translation.
2237 *) Add '-n' option to htpasswd to make it print its user:pw record
2238 on stdout rather than having to frob a text file. [Ken Coar]
2240 *) Fix saferead. Basically, we flush the output buffer if a read on the
2244 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2245 a conversion is single-byte only. [Jeff Trawick]
2247 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2248 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2251 *) Fix some minor errors where pid was being manipulated as an int
2252 instead of the portable pid_t. [Roy Fielding]
2254 *) Fix some error log prints that were printing the pointer to a
2255 structure rather than the pid within the structure.
2256 [Jeff Trawick, Roy Fielding]
2258 *) ab: Fix a command-line processing bug; track bad headers in
2259 err_response; support reading headers up to 2K.
2260 [Ask Bjoern Hansen <ask@valueclick.com>]
2262 *) Fix ap_resolve_env() so that it handles new function added in a prior
2263 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2264 config file.") as well as the constructs used by mod_rewrite.
2265 [Paul Reder <rederpj@raleigh.ibm.com>]
2267 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2269 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2270 APR to perform translation, instead of accessing the hard-coded tables
2271 in 1.3's ebcdic.c. [Jeff Trawick]
2273 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2276 *) Add the ability to hook into the config file reading phase. Basically
2277 if a directive is specified EXEC_ON_READ, then when that directive is
2278 read from the config file, the assocaited function is executed. This
2279 should only be used for those directives that must muck with HOW the
2280 server INTERPRETS the config. This should not be used for directives
2281 that re-order or replace items in the config tree. Those changes should
2282 be made in the pre-config step.
2285 *) Add mod_example to the build system.
2288 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2289 byte character sets. [Jeff Trawick]
2291 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2292 Kraemer and Oliver Reh originally according to the change log).
2295 *) Fix a couple of problems in RFC1413 support (controlled by the
2296 IdentityCheck directive). Apache did not build the request string
2297 properly and more importantly Apache would loop forever if the
2298 would-be ident server dropped the connection before sending a
2299 properly terminated response. [Jeff Trawick]
2301 *) apxs works in 2.0.
2304 *) Reliable piped logs work in 2.0.
2307 *) Introduce a hash table implementation into APR to be used for
2308 replacing tables and other random data structures in Apache.
2311 *) Add some more error reporting to htpasswd in the case of problems
2312 generating or accessing the temporary file. Also, pass in a
2313 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2314 is defined). [Ken Coar]
2316 *) Configure creates config.nice now containing your configure
2317 options. Syntax: ./config.nice [--more-options]
2320 *) Fix various return code problems in APR on Win32. For most of
2321 these, APR was returning APR_EEXIST instead of GetLastError()/
2322 WSAGetLastError(). [Jeff Trawick]
2324 *) Make piped logs work again in version 2.0
2327 *) Add VPATH support to UNIX build system of Apache and APR.
2330 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2334 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2335 Patch submitted to author.
2338 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2339 /sbin in PATH on FreeBSD (all submitted to rse previously)
2342 *) Fix building Pthread-based MPMs on OpenBSD
2343 [Sascha Schumann] PR#26
2345 *) Fix ap_readdir() problem on systems where d_name[] field in
2346 struct dirent is declared with only one byte. (This problem only
2347 affected multithreaded builds.) This caused a segfault during
2348 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
2349 least). [Jeff Trawick]
2351 *) Fix some make-portability problems on at least Tru64, Irix
2353 [Sascha Schumann] PR#18, PR#39
2355 *) Add ap_sigwait() to support old-style sigwait() on systems
2356 like OS/390 and UnixWare.
2359 *) Add POSIX-thread flags for more platforms.
2362 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2363 (on Unix, at least) to handle resolver errors. Fix a bug in
2364 the definition of APR_ENOMEM so that ap_strerror() can spit
2365 out the correct error message for it.
2368 Changes with Apache 2.0a3
2370 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2373 *) API: *HOOK* macros now have an AP_ prefix
2376 *) Win32: Eliminate redundant calls to initialize winsock.
2377 [Tim Costello <timcostello@ozemail.com.au>]
2379 *) Fix bugs initializing ungetchar for pipes.
2380 [Chia-liang Kao <clkao@CirX.ORG>]
2382 *) The ab program in the src/support directory is now portable using
2386 *) Support directory is being compiled when the server is built
2389 *) The configure option --with-program-name has been added to allow
2390 developers to rename the executable at configure time. This also
2391 changes the name of the config files to match the executable's name.
2394 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
2395 containing version numbers. [Martin Pool]
2397 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
2398 Unix; access_log and error_log now created with these perms; non-
2399 Unix is unaffected [Jeff Trawick]
2401 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
2402 Replaced more magic numbers with MD5_DIGESTSIZE.
2403 [William Rowe, Roy Fielding]
2405 *) Win32: Get mod_auth_digest compiling and added to the Windows
2406 build environment. Not tested and I'd be suprised if it
2407 actually works. [Bill Stoddard]
2409 *) Revamp the Win32 make environment. Makefiles have been removed and
2410 Apache.dsw created to bring together all the pieces. Create new file
2411 os/win32/BaseAddr.ref to define module base addresses (to prevent
2412 dll relocation at start-up).
2413 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
2415 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
2416 of the \015, \012, and \015\012 constants with macros.
2417 [Greg Ames <gregames@us.ibm.com>]
2419 *) Add ap_xlate_open() et al for translation of text between different
2420 character sets. The initial implementation requires iconv().
2423 *) More FAQs and answers from comp.infosystems.www.servers.unix.
2424 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2426 *) CGI output is being timed out now.
2429 *) Fix the problem with dieing quietly. dupfile now takes a pool which
2430 is used by the new apr file. There is no reason to create a new file
2431 with the same lifetime as the original file.
2434 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
2435 module base addresses. This will help shooting seg faults
2436 in the field. [William Rowe <wrowe@lnd.com>]
2438 *) Update Apache on Windows documentation. Add new document
2439 describing how to compile Apache on Windows.
2440 [William Rowe <wrowe@lnd.com>]
2442 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
2443 microseconds instead of seconds. Some storage leaks and other
2444 minor bugs in related code were fixed. [Jeff Trawick]
2446 *) Win32: First cut at getting mod_isapi working under 2.0
2447 [William Rowe <wrowe@lnd.com>]
2449 *) First stab at getting mod_auth_digest working under 2.0
2450 quick change summary:
2451 - moved the random byte generation (ap_generate_random_bytes) into APR
2452 - now uses ap_time_t
2453 - compiles and runs on linux
2455 [Brian Martin <bmartin@penguincomputing.com>]
2457 *) Win32: Move the space stripping of physical service names
2458 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
2459 unresolved symbol. Add dependency checking to the
2460 CreateService call to ensure TCPIP and AFP (winsock) is started
2462 [William Rowe <wrowe@lnd.com>]
2464 *) Win32: Add code to perform latebinding on functions that may
2465 not exist on all levels of Windows where Apache runs. This
2466 is needed to allow Apache to start-up on Win95/98. All calls
2467 to non portable functions should be protected with
2468 ap_oslevel checks to prevent runtime segfaults.
2469 [William Rowe <wrowe@lnd.com>]
2471 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
2473 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
2475 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
2476 This addresses PR 1623. Still need to address timing out runaway
2477 CGI scripts. [Bill Stoddard]
2479 *) Win32: Make ap_stat Windows 95/98 friendly
2480 [William Rowe <wrowe@lnd.com>]
2482 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
2483 always fail. Need to initialise the dwOSVersionInfoSize member of the
2484 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
2487 The patch also enhances ap_get_oslevel (and the associated enum) to
2488 handle selected service packs for NT4, and adds recognition for
2489 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
2490 we can use ReadFileScatter and WriteFileGather in readwrite.c.
2491 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
2493 *) Get mod_rewrite building and running, and mod_status building for Win NT
2494 [Allan Edwards <ake@raleigh.ibm.com>]
2496 *) Patch to port mod_auth_db to the 2.0 api and also to support
2497 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2498 2.7.7. It should work with version 1 as well but I haven't tested it.
2499 [Brian Martin <bmartin@penguincomputing.com>]
2501 *) Get APR DSO code working under Windows. Includes cross platform
2503 [Tim.Costello@BTFinancialgroup.com]
2505 *) Fix some of the Windows APR time functions.
2508 *) FAQ changes related to tidying up historical documents on the web site.
2509 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2511 *) Move Windows DSO code into APR.
2514 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
2515 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
2516 at build time. At this point, the server will not compile on Windows because
2517 of the recent DSO commits. Fixing those next.
2518 [Bill Rowe & Bill Stoddard]
2520 *) Added error checking for file I/O APR routines.
2521 [Jon Travis <jtravis@covalent.net>]
2523 *) APR: Don't use the values of resolver error codes for the
2524 corresponding APR error codes. On Unix and Win32, return the
2525 proper APR error code after a resolver error. [Jeff Trawick]
2527 Changes with Apache 2.0a2
2529 *) Renamed the executable back to httpd on all platforms other
2533 *) Allow BeOS to survive restarts, log properly and a few
2534 small things it had problems with due to the way it setup
2535 users and groups. [David Reid]
2537 *) Get mod_rewrite working with APR locks
2538 [Paul Reder <rederpj@raleigh.ibm.com>]
2540 *) Actually remove the sempahore when the lock cleanup routine
2541 is called on BeOS. [David Reid]
2543 *) Clear hook registrations between reads of the config file.
2544 When DSOs are unloaded and re-loaded the old hook pointers may
2545 no longer be valid. This fix eliminates potential segfaults.
2546 [Allan Edwards <ake@raleigh.ibm.com>]
2548 *) Fix a problem with Sigfunc not being defined or bypassed
2549 if sigaction() wasn't found. [Jim Jagielski]
2551 *) Fix the locking mechanism on BSD variants. They now use fcntl
2552 locks. This allows the server to start and serve pages.
2555 *) First cut at getting the Win32 installer to work
2556 [William Rowe <wrowe@lnd.com>]
2558 *) Get htpasswd compiling under Windows
2559 [William Rowe <wrowe@lnd.com>]
2561 *) Change the log message for a bind() failure to show the
2562 interface and port number. [Jeff Trawick]
2564 *) Import the documentation from 1.3.12 and bring parts of it
2565 up-to-date with respect to the changes that have occurred
2569 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
2570 now logged correctly on BeOS.
2573 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
2574 Makefile.win includes the same user interface as the old
2576 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
2578 *) Win32 exec now uses COMSPEC environment string for command
2579 shell path resolution.
2580 [William Rowe <wrowe@lnd.com>] PR#3715
2582 *) Win32: ap_connect() was not returning correct error condition
2584 [Allen Prescott <allen@clanprescott.com>]
2586 *) Win32: ap_open() was broken on Win9x because an NT-specific
2587 flag was passed to CreateFile. ap_puts() added an unnecessary
2589 [Jeff Trawick <trawick@us.ibm.com>]
2591 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
2592 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
2593 confusing ee/et name and made all extensions language/dialect
2594 rather than country reflecting. Changed example files to
2595 explicit reflect the ISO charset and added a few common
2596 ones to the example config [dirkx]
2598 *) Extend external module capability. To use this, you call
2599 configure with --with-module=path/to/mod1,path/to/mod2,etc.
2602 *) Backported the various "default charset" fixes from 1.3.12,
2603 including the AddDefaultCharset directive. [Jim Jagielski]
2605 *) Added the capability to do ${ENVVAR} constructs in the
2606 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
2607 it does this on a line by line basis; i.e. if the envvar
2608 expands to something with spaces you have to protect it
2609 by adding quotes around it (Unless of course you expect it
2610 to contains more than one argument. Alternatively you
2611 can compile it on a per token basis; which is what people
2612 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
2613 hampers fancier hacks.
2614 [Dirk-Willem van Gulik]
2616 *) Changed the 'ErrorDocument' syntax in that it NO longer
2617 supports the asymetric
2619 ErrorDocument 301 "Some message
2621 Note the opening " quote, without a closing quote. It now
2622 has either the following syntaxes
2624 ErrorDocument XXX /local/uri
2625 ErrorDocument XXX http://valid/url
2626 ErrorDocument XXX "Some Message"
2628 The recognition heuristic is: if it has a space it
2629 is a message. If it has no spaces and starts with a /
2630 or is a valid URL then treat it that way. Otherwise it
2631 is assumed to be a message.
2633 This breaks backward compatibility but makes live a hell
2634 of a lot easier for GUI's and config file parsers.
2635 [Dirk-Willem van Gulik]
2637 *) Changed 'CacheNegotiatedDocs' from its present/not-present
2638 syntax into a 'on' or 'off' syntax. As it currently is the
2639 only non nesting token which uses NO_ARGS and thus is an
2640 absolute pain for any config interface automation. This
2641 breaks backward compatibility. [Dirk-Willem van Gulik]
2643 *) Add ability to add external modules to the build process. This is
2644 done with --with-module=/path/to/module. Modules can only be added
2645 as static modules at this point.
2648 Changes with Apache 2.0a1
2650 *) Fix FreeBSD 3.3 core dump.
2651 Basically, ap_initialize() needs to get called before
2652 create_process(), since create_process() passes op_on structure
2653 to semop() to get a lock, but op_on isn't initialized until
2654 ap_initialize() calls setup_lock(). Here is a slight
2655 rearrangement to main() which calls ap_initialize() earlier...
2656 [Jeff Trawick <trawick@us.ibm.com>]
2658 *) Enable Apache to use sendfile/TransmitFile API
2659 [Bill Stoddard, David Reid, Paul Reder]
2661 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
2665 *) Make file I/O and network I/O writev/sendv APIs consistent.
2666 Eliminate use of ap_iovec_t and use Posix struct iovec.
2667 Use seperate variable on ap_writev to set the number of iovecs
2668 passed in and number of bytes written.
2671 *) Adapt file iol to use APR functions. Replaced ap_open_file()
2672 with ap_create_file_iol(). ap_create_file_iol() requires that
2673 the file be opened prior to the call using ap_open().
2676 *) Port mod_include and mod_cgi to 2.0
2677 [Paul Reder, Bill Stoddard]
2679 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2680 bytes_read/bytes_written is always valid (never -1). Plus
2681 some fixes to buff.c to correct problems introduced by the
2682 errno => ap_status_t changes a while back. Plus a fix to
2683 chunked encoding introduced right at the beginning of 2.0.
2686 *) Revamped UNIX build system to use autoconf and libtool.
2687 [Manoj Kasichainula, Sascha Schumann]
2689 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2691 *) More rigorous checking of Host: headers to fix security problems
2692 with mass name-based virtual hosting (whether using mod_rewrite
2693 or mod_vhost_alias).
2694 [Ben Hyde, Tony Finch]
2696 *) Add back support for UseCanonicalName in <Directory> containers.
2697 [Manoj Kasichainula]
2699 *) Added APLOG_STARTUP log type. This allows us to write an error
2700 message without any of the date and time information. As a part
2701 of this change, I also removed all of the calls to fprintf(stderr
2702 and replaced them with calls to ap_log_error using APLOG_STARTUP
2703 writing to stderr is no longer portable, because we don't direct
2704 stderr to the error log on all platforms.
2707 *) Convert error logging functions to take errno as an argument.
2708 This makes our error logs more portable, because some Windows API's
2709 don't set errno. This change allows us to still output a valid
2710 message on all of our platforms.
2713 *) mod_mime_magic runs in 2.0-dev now.
2714 [Paul Reder <rederpj@raleigh.ibm.com>]
2716 *) sendfile has been added to APR.
2717 [John Zedlewski <zedlwski@Princeton.EDU>]
2719 *) buff.c has been converted to no longer use errno.
2720 [Manoj Kasichainula]
2722 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2723 interface adaption to APR functions did it. [Martin Kraemer]
2725 *) Support DSOs properly on 32-bit HP-UX 11.0
2726 [Dilip Khandekar <dilip@cup.hp.com>]
2728 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2729 [Ralf S. Engelschall]
2731 *) Cleaned APR build environment integration and bootstrap APR
2732 automatically for developers from src/Configure.
2733 [Ralf S. Engelschall]
2735 *) Fixed building of src/support/htpasswd.c
2736 [Ralf S. Engelschall]
2738 *) When generating the Location: header, mod_speling forgot
2739 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2742 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2744 *) Change all pools to APR contexts. This is the first step to
2745 incorporating APR into Apache. [Ryan Bloom]
2747 *) Move "handler not found" warning message to below the check
2748 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2749 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2751 *) Support line-continuation feature in config.option file and
2752 allow the loading of multiple option sections at once via
2753 ``--with-option=<section1>,<section2>,...''
2754 [Ralf S. Engelschall]
2756 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2758 Changes with Apache MPM
2760 *) Use asynchronous AcceptEx() and a completion port to accept and
2761 dispatch connections to threads in Windows NT/2000.
2764 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2767 *) Implement the APACI --with-option facility
2768 (per default used the config.option file).
2769 [Ralf S. Engelschall]
2771 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2773 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2774 Replace pre_connection module call with a register_hook call and
2775 implement pre_connection as a hook. The intent is that these hooks will
2776 be extended to allow Apache to be multi-protocol, and also to allow the
2777 calling order to be specified on a per-hook/per-module basis.
2780 *) Implement mpm_* methods as "modules". Each method gets its own
2781 subdir in src/modules (eg: src/modules/prefork). Selection
2782 of method uses Rule MPM_METHOD. [Jim Jagielski]
2784 *) Port the hybrid server from the apache-apr repository as
2785 mpm_mpmt_pthread. [Manoj Kasichainula]
2787 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2788 amongst the unix MPMs.
2790 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2791 signal handling for the new world order. [Dean Gaudet]
2793 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2794 of alloc.c for now. [Dean Gaudet]
2796 *) Handle partial large writes correctly. [Ben Laurie]
2798 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2799 based on IP/port. [Ben Laurie]
2801 *) Port a bunch of modules to the new module structure.
2802 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2804 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2806 *) Basic restructuring to introduce the MPM concept; includes various
2807 changes to the module API... better described by
2808 docs/initial_blurb.txt. [Dean Gaudet]
2810 Changes with Apache pthreads
2812 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2813 buff operations (generally over a network).
2814 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2816 *) Created http_accept abstraction. Added 4 new functions (not exported):
2817 init_accept(), begin_accepting_requests(), get_request(),
2818 stop_accepting_requests() [Bill Stoddard]
2820 *) Fix to ap_rprintf call that allows mod_info to work properly.
2821 [James Morris <jmorris@intercode.com.au>]
2823 *) user and ap_auth_type fields were moved from connection_rec to
2824 request_rec. [Ryan Bloom]
2826 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2827 needed in a threaded server.
2829 *) Initial pthread implementation from from Dean's apache-nspr code.
2830 [Bill Stoddard, Ryan Bloom]
2833 Changes with Apache 1.3.9
2835 *) Remove bogus error message when a redirect doesn't set Location.
2836 Instead, use an empty string to avoid coredump if the error message
2837 was supposed to include a location. [Roy Fielding]
2839 *) Don't allow configure to include mod_auth_digest unless it is
2840 explicitly requested, even if the user asked for all modules.
2843 *) Translate module names to dll names for OS/2 so that they are no more
2844 than 8 characters long and have an extension of "dll" instead of "so".
2847 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2848 Fix test-compile check to check for randbyte instead of trand32.
2849 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2850 and tweak to make Amaya happier. [Ronald Tschalär]
2852 *) Ensure that the installed expat include files are world readable,
2853 just like the other header files. [Martin Kraemer]
2855 *) Fixed generated AddModule adjustments in APACI's `configure' script
2856 in order to allow (new) modules like mod_vhost_alias to be handled
2857 correctly (which was touched by the adjustments for mod_alias).
2858 [Ralf S. Engelschall]
2860 *) For binary builds, add -R flag to apachectl to work around the lack of
2861 an absolute path to the ./libexec directory where the libhttp.ep file
2862 is needed for SHARED_CORE architectures. [Randy Terbush]
2864 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2865 problem observed by some Win95/98 users where they get CGI script
2866 output sent to the console. [Bill Stoddard]
2868 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2869 routines are now called ap_base64* and are 'plain' (i.e., no
2870 pool access or anything clever). Inside util.c the routines acting
2871 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2872 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2873 now but deprecated. [dirkx]
2875 *) Clean up the base64 and SHA1 additions and make sure they are
2876 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2877 files. [Roy Fielding]
2879 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2880 checking. Allow compiling on VS 6.0. [Randy Terbush]
2882 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2884 *) Use TestCompile to search for the truerand library (rather than blindly
2885 assuming its existence). If it is not found, complain (but do not
2886 exit - yet). [Martin Kraemer]
2888 *) We forgot to add the new exported function names to
2889 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
2891 *) Add description of -T command-line option to usage().
2892 [Ralf S. Engelschall]
2894 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
2895 searched only AFTER libap has been searched, because libap needs
2896 some symbols from libos. [Martin Kraemer]
2898 *) Fix conflict with original mod_digest related to the symbol of the
2899 module dispatch list (which has to be unique for DSO and follow the
2900 usual conventions for the installation procedure).
2901 [Ralf S. Engelschall]
2903 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
2904 for other platforms as well. [Martin Kraemer]
2906 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
2907 types by AP_LONG and replace reference to renamed variable 'ubuf'
2908 by 'buffer'. [Martin Kraemer]
2910 Changes with Apache 1.3.8 [not released]
2912 *) Flush the output buffer immediately after sending an error or redirect
2913 response, since the result may be needed by the client to abort a
2914 long data transfer or restart a series of pipelined requests.
2915 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
2917 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
2918 [Ian Turner <iant@sequent.com>] PR#4735
2920 *) Local struct mmap in http_core.c conflicted with system structure
2921 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
2923 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
2924 [Ronald Tschalär <ronald@innovation.ch>]
2926 *) Fix a memory leak where the module counts were getting messed
2927 up across restarts. [David Harris <dharris@drh.net>]
2929 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
2930 properly in mod_access.
2931 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
2933 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.

2936 *) PORT: Support for compaq/tandem/com.
2937 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
2939 *) Added SHA1 password encryption support to easy migration from
2940 Netscape servers. See support/SHA1 for more information.
2941 Caused the separation of ap_md5.c into md5, sha1 and a general
2942 ap_checkpass.c with just a validate_passwd routine. Added a
2943 couple of flags to support/htpasswd. Some reuse of the to64()
2944 function; hence renamed to ap_to64().

2947 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
2948 with ASCII/EBCDIC conversions in "ident" query.
2949 [David McCreedy <McCreedy@us.ibm.com>]
2951 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
2952 Change "Power Macintosh" to Power* so if uname prints "Power Book"
2953 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
2955 *) Fix SIGSEGV on some systems because the Vary fix below included
2956 a call to table_do with a variable argument list that was not
2957 NULL terminated. Replaced with better implementation. [Roy Fielding]
2959 Changes with Apache 1.3.7 [not released]
2961 *) The "Vary" response header field is now sanitised right before
2962 the header is sent back to the client. Multiple "Vary" fields
2963 are combined, and duplicate tokens (e.g., "Vary: host, host" or
2964 "Vary: host, negotiate, host, accept-language") are reduced to
2965 single instances. This is a better solution than the force-no-vary
2966 one (which is still valid for clients that can't cope with Vary
2967 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
2969 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
2971 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
2972 least on Linux and FreeBSD for now.
2975 *) Win32: More apache -k restart work. Restarts are now honored
2976 immediately and connections in the listen queue are -not- lost.
2977 This is made possible by the use of the WSADuplicateSocket()
2978 call. The listeners are opened in the parent, duplicated, then
2979 the duplicates are passed to the child. The original listen sockets
2980 are not closed by the parent across a restart, thus the listen queue
2982 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2984 *) Fix handling of case when a client has sent "Expect: 100-continue"
2985 and we are going to respond with an error, but get stuck waiting to
2986 discard the body in the pointless hope of preserving the connection.
2987 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
2989 *) Fix 'configure' to work correctly with SysV-based versions of
2990 'tr' (consistent with Configure's use as well). [Jim Jagielski]
2992 *) apxs: Add "-S var=val" option which allows for override of CFG_*
2993 built-in values. Add "-e" option which works like -i but doesn't
2994 install the DSO; useful for editing httpd.conf with apxs. Fix
2995 editing code so that multiple invocations of apxs -a will not
2996 create duplicate LoadModule/AddModule entries; apxs can now be
2997 used to re- enable/disable a module. [Wilfredo Sanchez]
2999 *) Win32: Update the server to use Winsock 2. Specifically, link with
3000 ws2_32.lib rather than wsock32.lib. This gives us access to
3001 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3002 Win 95 users may need to update their TCP/IP stack to pick up
3003 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3004 [Bill Stoddard stoddard@raleigh.ibm.com]
3006 *) Win32: Redirect CGI script stderr (script debug info) into the
3007 error.log when CGI scripts fail. This makes Apache on Win32
3008 behave more like Unix.

3028 command potentially _is_ GCC. [Ralf S. Engelschall]
3030 *) Fix apxs build issues on AIX
3031 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3033 *) DocumentRoot Checking: Under previous versions, when Apache
3034 first started up, it used to do a stat of each DocumentRoot to
3035 see if it existed and was a directory. If not, then an error
3036 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3037 does not exist, you will get error messages in error_log. If
3038 the '-t' command line option is used (to check the configuration)
3039 the check of DocumentRoot IS performed. An additional command
3040 line option, '-T', has been added if you want to avoid the
3041 DocumentRoot check even when checking the configuration.
3044 *) Win32: The query switch "apache -S" didn't exit after showing the
3045 vhost settings. That was inconsistent with the other query functions.
3046 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3048 *) Win32: Changed behaviour of apache -k restart.
3049 Previously, the server would drain all connections in the stack's
3050 listen queue before honoring the restart. On a busy server, this
3051 could take hours. Now, a restart is honored almost immediately.
3052 All connections in Apache's queues are handled but connections in
3053 the stack's listen queue are discarded. Restart triggered by
3054 MaxRequestPerChild is unchanged.
3055 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3057 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3058 the accept loop. Good for a 5% performance boost. Cleaned up

3078 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3079 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3081 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3082 never accepted into any standard, and it opens up certain DoS
3083 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3085 *) TestCompile updated. We can now run programs and output the
3086 results during the Configure process. [ Jim Jagielski]
3088 *) The source is now quad (long long) aware as needed. Specifically,
3089 the Configure process determines the correct size of off_t and
3090 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3091 provides for the 'q' format qualifier (if quads are not available,
3092 'q' is silently "demoted" to long). [Jim Jagielski]
3094 *) When the username or password fed to htpasswd is too long, include the
3095 size limit in the error message. Also report illegal characters
3096 (currently only ':') in the username. Add the size restrictions
3097 to the man page. [Ken Coar]
3099 *) Fixed the configure --without-support option so it doesn't result in
3100 an infinite loop. [Marc Slemko]

3103 during configuration after a restart.
3104 [Aidan Cully <aidan@panix.com>] PR#4456
3106 *) If a "Location" field was stored in r->err_headers_out rather
3107 than r->headers_out, redirect processing wouldn't find it and
3108 the server would core dump on ap_escape_html(NULL). Check both
3109 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3110 if Location isn't set. [Doug MacEachern, Ken Coar]
3112 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3113 of the Expat 1.0.2 distribution. [Greg Stein]
3115 *) Replace regexec() calls with calls to a new API stub function
3116 ap_regexec(). This solves problems with DSO modules which use the regex
3117 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3119 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3120 environment variables can be set according to the protocol version
3121 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

3138 *) Support for server-parsed and multiview-determined ReadmeName and
3139 HeaderName files in mod_autoindex. Removed the restriction on
3140 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3141 routines will deal with the access issues. (It's now possible to

3157 by default when building with APACI; allow for platform-specific
3158 variable defaults in configure. [Wilfredo Sanchez]
3160 *) Do setgid() before initgroups() in http_main; some platforms
3161 zap the grouplist when setgid() is called. This was fixed in
3162 suexec earlier, but the main httpd code missed the change.

3179 when using APACI and shadow sources. [Wilfredo Sanchez]
3181 *) PORT: Add initial support for Mac OS (versions 10.0 and
3182 greater). Use Mac OS X Server layout for now. Clean up dyld code
3183 in unix/os.c, and don't install the dyld error handlers, which
3184 are no longer needed in Mac OS. [Wilfredo Sanchez]
3186 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3187 locations to appropriate ones for user-built (as opposed to
3188 system) installs. [Wilfredo Sanchez]
3190 *) Modify mod_autoindex's handling of AddDescription so that the
3191 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3193 *) Add functionality to the install-bindist.sh script created by
3194 binbuild.sh to use tar when copying distribution files to the
3195 serverroot. This allows upgrading an existing installation
3196 without nesting the new distribution in the old.
3198 install-bindist.sh now detects the local perl5 path to install
3199 apxs and dbmmanage with proper path to perl interpreter.
3201 Add an install-binsupport target which copies the source files
3202 for apxs and dbmmanage to bindist to allow these scripts to
3203 be properly installed relative to the destination serverroot.

3370 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
3371 a roughly 5 fold speed up. [Brian Havard]
3373 *) proxy ftp: instead of using the hardwired string "text/plain" as
3374 a fallback type for files served by the ftp proxy, use the
3375 ap_default_type() function to determine the configured type.
3376 This allows for special configurations like
3377 <Directory proxy:ftp://some.host>
3378 DefaultType gargle/blurb
3380 Additionally, add the Content-Encoding: header to FTP proxy replies
3381 when the encoding is defined (by the AddEncoding directive).
3382 Because it was missing, it was almost impossible to browse compressed
3383 files using the FTP proxy (works now perfectly in Communicator).
3384 The ftp proxy now also returns the Date: and Server: header lines (if not
3385 much else... This code is "somewhat" broken) like normal requests do.
3388 *) Be more smart in APACI's configure script when determining the UID/GID

3467 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
3468 because SPARCs have a small machine-specific maximum size for the Global

3505 *) In configure, do not append the target name to the directory path if
3506 the path already contains "apache". [Ralf S. Engelschall]
3508 *) SIGPIPE is now ignored by the server core. The request write routines
3509 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
3510 correctly check for output errors and mark the connection as aborted.
3511 Replaced many direct (unchecked) calls to ap_b* routines with the
3512 analogous ap_r* calls. [Roy Fielding]
3514 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
3515 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
3516 Furthermore map lookups for non-existent keys are now cached as well.
3517 Additionally "txt" maps are now parsed with simple string functions
3518 instead of using ap_pregcomp(). As a side effect a bug that prevented
3519 the usage of keys containing the "," character was fixed.
3520 The changes drastically improve the performance when large rewrite maps

3563 characters in the range 0x80 to 0xff (for example accented characters).
3564 [Paul Sutton] PR#3890
3566 *) Added conditional logging based upon environment variables to
3567 mod_log_config. mod_log_referer and mod_log_agent
3568 are now deprecated. [Ken Coar]
3570 *) Allow apache acting as a proxy server to relay the real
3571 reason of a failure to a client rather than the "internal
3572 server error" it does currently. The general exposure mechanism
3573 can be triggered by any module by setting the "verbose-error-to"
3574 note to "*"; this allows more than just proxy errors to be exposed.

3583 *) Tweak modules Makefile generated by Configure so that it handles
3584 the test case of no modules being selected. [chaz@reliant.com]
3586 *) Added a <LimitExcept method ...> sectioning directive that allows
3587 the user to assign authentication control to any HTTP method that
3588 is *not* given in the argument list; i.e., the logical negation
3589 of the <Limit> directive. This is particularly useful for controlling
3590 access on methods unknown to the Apache core, but perhaps known by
3591 some module or CGI script. [Roy Fielding, Tony Finch]
3593 *) Prevent apachectl from complaining if the PIDFILE exists but
3594 does not contain a process id, as might occur if the server is
3595 being rapidly restarted. [Wilfredo Sanchez]

3607 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
3608 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
3610 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
3611 to util.c for parsing an HTTP header field value to extract the next
3612 list item, taking into account the possible presence of nested comments,
3613 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
3614 insignificant whitespace and lowercases non-quoted tokens.
3615 [Roy Fielding] PR#2065
3617 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
3618 code different from 500. This allows the proxy to, e.g., return
3619 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
3621 *) Fix ordering of language variants for the case where the traditional
3622 negotiation algorithm is being used with multiple language variants
3623 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
3625 *) Do not round the TCN quality calculation to 5 decimal places,
3626 unlike RFC 2296, because the calculation might need 12 decimal places
3627 to get the right result. [Roy Fielding]
3629 *) Remove unused code to disable transparent negotiation when
3630 negotiating on encoding only, as we now handle encoding too
3631 (though this is nonstandard for TCN), remove charset=ISO-8859-1
3632 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
3633 some debugging statements within mod_negotiation. [Koen Holtman]
3635 *) Fixed a rare memory corruption possibility in mod_dir if the index
3636 file is negotiable and no acceptable variant can be found.
3637 [Dean Gaudet, Roy Fielding, Martin Kraemer]
3639 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
3640 searching the Win32 registry for script interpreters.
3643 *) Win32: The compiled-in default filename for the error log is now
3644 error.log, which matches the default in the distributed httpd.conf.
3647 *) Win32: Any error messages from -i or -u command line options are now
3648 displayed on the console output rather than sent to the error log.
3649 Also the "Running Apache..." message is not output unless Apache is
3650 going to serve requests. [Paul Sutton]
3652 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
3653 and use a private significator ('$apr1$') to mark passwords as
3654 being smashed with our own algorithm. Also abstract the password
3655 checking into a new ap_validate_password() routine. [Ken Coar]
3657 *) Win32: The filename validity checker now allows "COM" but refuses
3658 access to "COM1" through "COM4". This allows filenames such
3659 as "com.name" to be served. [Paul Sutton] PR#3769.
3661 *) BS2000: Adapt to the new ufork() system call interface which will
3662 make subtasking easier on the OSD/POSIX mainframe environment.
3665 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
3666 ap_compat.h. [David White <david@persimmon.com>] PR#3725
3668 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.

3670 the NDBM library looks like Berkeley-DB based.

3678 *) SECURITY: Avoid some buffer overflow problems when escaping
3679 quoted strings. (This overflow was on the heap and we believe
3680 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
3682 *) Let src/Configure be aware of CFLAGS options starting with plus
3683 signs as it's the case for the HP/UX compiler.
3684 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
3686 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
3687 and check to see if the tar we wind up with supports '-h'.
3688 [Jim Jagielski] PR#3671
3690 *) A consistent and conservative style for all shell scripts has been
3691 implemented. Basically, all shell string tests use the traditional
3692 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3693 to protect against bare null variable strings (ie: wrapping both
3694 sides with double quotes and prepending 'x'). 'x' was chosen
3695 because it's more universal and hopefully easier for old shell
3696 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3699 *) The status module now prints out both the main server generation as
3700 well as the generation of each process. Also, the vhost info is
3701 printed with '?notable'. [Jim Jagielski]
3703 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3704 and this makes its functions available to things in src/support.
3707 Changes with Apache 1.3.4
3709 *) Renamed macros status_drops_connection to ap_status_drops_connection
3710 and vestigial scan_script_header to ap_scan_script_header_err,
3711 mostly for aesthetic reasons. [Roy Fielding]
3713 *) The query switch "httpd -S" didn't exit after showing the
3714 vhost settings. That was inconsistent with the other query functions.
3717 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
3718 filename to the end of the STANDARD_MODULE_STUFF. Its
3719 presence at the beginning prevented reporting of the filename
3720 for modules compiled before 1 January 1999. [Ken Coar]
3722 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
3723 to detect and prevent access to special DOS device file names.
3724 [Paul Sutton, Ken Parzygnat]
3726 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
3727 and Makefile_win32_debug.txt (debug build) that work on Win95.
3728 Run each of the following from the src directory:
3729 nmake /f Makefile_win32.txt # compiles normal build
3730 nmake /f Makefile_win32.txt install # compiles and installs
3731 nmake /f Makefile_win32.txt clean # removes compiled junk
3732 nmake /f Makefile_win32_debug.txt # compiles debug build
3733 nmake /f Makefile_win32_debug.txt install
3734 nmake /f Makefile_win32_debug.txt clean
3737 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3738 to build binary distributions. [Lars Eilebrecht]
3740 *) IndexOptions SuppressColumnSorting only turned off making
3741 the column headers anchors; you could still change the display
3742 order by manually adding a '?N=A' or similar query string to the
3743 URL. Now SuppressColumnSorting locks in the sort order so
3744 it can't be overridden this way. [Ken Coar]
3746 *) Added IndexOrderDefault directive to supply a default sort order
3747 for FancyIndexed directory listings. [Ken Coar] PR#1699
3749 *) Change the ap_assert macro to a variant that works on all platforms.
3750 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3752 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3753 search for an underscore on dlsym() (as it's already the case
3754 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3756 *) Small fix for mod_env.html: The module was documented as to be _not_
3757 compiled into Apache per default, although it _IS_ compiled into
3758 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3760 *) Instead of fixing a bug in the generation procedure for config.status (a
3761 backslash was missing) we remove the bug together with it's complete
3762 context because the special cases of the past can now no longer occur
3763 because of the recent magic for the --with-layout default.
3764 [Ralf S. Engelschall] PR#3590
3766 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3767 making sure the src/support/ tools are _forced_ to be build last (they
3768 depend on other libraries).
3769 [Markus Theissinger <markus.theissinger@gmx.de>]
3771 *) Fix installation procedure: Now that os-inline.c is actually used (a
3772 recently fixed bug prevented this) we need to also install os-include.c
3773 in addition to os.h into the PREFIX/include/ location or building of
3774 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3776 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3777 allow us to distinguish between a garbled DSO (or even a file which isn't
3778 an Apache module DSO at all) and a DSO which doesn't match the current
3779 Apache API. [Ralf S. Engelschall] PR#3152
3781 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3782 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3783 match case insensitive (this especially avoids nasty patterns like
3784 `[tT][eE][sS][tT]'). Second two additional internal map functions
3785 `escape' and `unescape' were added which can be used to escape/unescape
3786 to/from hex-encodings in URLs parts (this is especially useful in
3787 combination with map lookups).
3788 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3790 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3791 forgotten (because it was a macro) in the symbol renaming process.
3792 [Ralf S. Engelschall]
3794 *) Fix some inconsistencies related to the scopes of directives. The only
3795 user visible change is that the directives `UseCanonicalName' and
3796 `ContentDigest' now use the (more correct) `Options' scope instead of
3797 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3799 *) Using DSO, the Server token was being mangled. Specifically, the
3800 module's token was being added first before the Apache token. This
3801 has been fixed. [Jim Jagielski]
3803 *) Major overhaul of mod_negotiation.c, part 2.
3804 - properly handle "identity" within Accept-Encoding.
3805 - allow encoded variants in RVSA negotiation and let them appear in
3806 the Alternates field using the non-standard "encoding" tag-list.
3807 - fixed both negotiation algorithms so that an explicitly accepted
3808 encoding is preferred over no encoding if "identity" is not
3809 included within Accept-Encoding.
3810 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3811 of large substring sequences.
3812 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3815 *) Major overhaul of mod_negotiation.c, part 1.
3816 - cleanups to mod_negotiation comments and code structure
3817 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3818 support for everything in the upcoming HTTP/1.1
3819 revision (draft-ietf-http-v11-spec-rev-06.txt).
3820 - language tag matching also handles tags with more than 2
3822 - empty Accept, Accept-Language, Accept-Charset headers are
3823 processed correctly; previously an empty header would make all
3824 values acceptable instead of unacceptable.
3825 - allowed for q values in Accept-Encoding
3826 - added support for transparent content negotiation (rfc2295 and
3827 rfc2296) (though we do not implement all features in these drafts,
3828 e.g. no feature negotiation). Removed old experimental version.
3829 - implemented 'structured entity tags' for better cache correctness
3830 (structured entity tags ensure that caches which can deal with Vary
3831 will (eventually) be updated if the set of variants on the server
3833 - this involved adding a vlist_validator element to request_rec
3834 - this involved adding the ap_make_etag() function to the global API
3835 - modified guessing of charsets used by Apache negotiation algorithm
3836 to guess 'no charset' if the variant is not a text/* type
3837 - added code to sort multiviews variants into a canonical order so that
3838 negotiation results are consistent across backup/restores and mirrors
3839 - removed possibility of a type map file resolving to another type map
3840 file as its best variant
3841 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987

3854 *) For %v log ServerName regardless of the UseCanonicalName
3855 setting (similarly for %p). [Dean Gaudet]
3857 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
3858 rather late (too late for some invocations of TestCompile).
3859 This improves the make environment available to TestCompile and
3860 the *.module scripts. [Martin Kraemer]
3862 *) The hashbang emulation code in ap_execve.c would interpret
3863 #!/hashbang/scripts correctly, but failed to fall back to a
3864 standard shell for scripts which did NOT start with #!
3865 Now SHELL_PATH is started in these cases. [Martin Kraemer]
3867 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
3870 *) Update APXS manual page: some -q option arguments were missing
3871 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3873 *) Cleanup the command line options: `-?' was documented to show
3874 the usage list but does it with an error because `?' is not a valid
3875 command. OTOH a lot of users expect `-h' to print such a usage list and
3876 instead are annoyed for ages by our huge unreadable list of directives.
3877 So we now changed the command line options this way:
3879 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3880 very similar to the popular linker option.
3882 Intent: while -l gives the small list of modules, -L now gives the
3883 large list of directives implemented by these modules. This is also
3884 consistent with -v (short version info) and -V (large version info).
3886 Intent: it's now the expected option ;-)
3887 The manual page was adjusted accordingly.
3888 [Ralf S. Engelschall] PR#2714
3890 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
3891 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
3893 *) Removed recently introduced bugs and disfigurements in APACI:
3894 o fixed argument line processing: using $args was broken: It was not
3895 initialized and using args="$args $apc_option" and even args="$args
3896 \"$apc_option\"" fails in the second processing round for any arguments
3897 containing whitespaces. The only correct way is to use the construct
3898 "$@" (but not possible here) or iterate _both_ times over the implicit
3899 argument line (no argument to for-loop) which is what we now use.
3900 o make --with-layout=Apache the default without creating
3901 redundancy (copying the --with-layout block in the argument parsing
3902 loop). We achieve this by using the "$@" construct together with the
3903 `set' command to prepend --with-layout=Apache to the command line in
3904 case --with-layout is not used.
3905 o fixed auto-suffix handling now that config.layout exists.
3906 Paths which are auto-suffixed are marked with a trailing plus sign in
3907 config.layout and every path now can be marked this way (not only the
3908 four paths for which we do it currently). Additionally the suffix is
3909 no longer a static one. Instead it's now `/<target>' where <target> is
3910 the argument of the --target option or per default `httpd'.
3911 o allow also tabs (and only spaces) where we match whitespaces
3912 o various fixes and cleanups related to used shell coding style
3913 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
3914 o trimmed output of --help to fit into 80 columns
3915 [Ralf S. Engelschall]

3926 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
3927 of ap_config.h that would skip several defines if DEFAULT_GROUP
3928 was overridden. [Roy Fielding]
3930 *) PORT: The I86 version of DGUX has support for strncasecmp and
3931 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
3933 *) Fix ordering of definitions in ap_config.h so that ap_inline is
3934 defined before it might be used. [Victor Khimenko]
3936 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
3937 [Tom Serkowski <tks@bsdi.com>] PR#3453
3939 *) Make generation of src/Configuration.apaci more robust: It failed to
3940 differenciate between modules when one module name was a postfix of
3941 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
3942 just XXX (think about totally non-standard names like "apache_ssl", too).
3943 [Ralf S. Engelschall] PR#3380
3945 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
3946 since 1.3b7) and make whitespace handling more robust (it failed horrible
3947 when whitespaces were present in the arguments of -D options).
3948 [Ralf S. Engelschall] PR#3240
3950 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
3951 creates an external package shadow tree in DIR before the local build
3952 shadow tree is generated under DIR. This way one can have the extracted
3953 Apache distribution tree read-only on NFS or CDROM and still build Apache
3954 from these sources. An automatically triggered VPATH-like mechanism is
3955 provided through the TOP variable, too.

3959 generated when, for a particular dimension, variants only vary
3960 in having or not having a value for that dimension. [Paul Sutton]

3963 unencoded variant if the user-agent explicitly says it can
3964 accept that encoding. Previously we always preferred the unencoded
3966 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
3968 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
3969 and the usage page was inconsistent with the functionality and manpage.
3970 [Ralf S. Engelschall]
3972 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
3973 They can occur multiple times and their arguments (`xxx') are passed AS
3974 IS to the compiler/linker command. [Ralf S. Engelschall]
3976 *) Fixed possible (but harmless in practice) bug in the DBM lookup
3977 procedure of mod_rewrite: very long keys were truncated.
3978 [Ralf S. Engelschall]
3980 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
3981 identifier, currently "Apache" and "GNU" are pre-defined in the file
3982 config.layout. Custom layouts are possible by using FILE:ID as the
3983 argument where the layout ID is taken from FILE.
3985 The config.layout file consists of <Layout ID>..</Layout> sections
3986 where inside those sections "path_variable: path_value" pairs can be
3987 specified. These lines are converted to path_variable='path_value'.
3989 *) Add a DefaultLanguage directive so that files missing a language
3990 extension (e.g., .fr, .de) can be labelled as being some other
3991 default language. DefaultLanguage can appear in <Directory> and
3992 <Files> containers as well as .htaccess files. [Paul Sutton]
3995 *) Fix TARGET configuration when configuring and installing using
3996 APACI configure. TARGET now defines the basename of the configuration
3997 file, startup script, manual page, etc. log_error_core() now reports
3998 the server binary name given by argv[0]. TARGET can now also be defined
3999 with --target=TARGET parameter passed to APACI configure.

4002 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
4003 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

4022 notice to the error log. It is not possible to send a 401 response
4023 and a redirect at the same time. [Lars Eilebrecht]
4025 *) Fallback to native compilers for IRIX-32 platform. It seems that
4026 a gcc 2.8.1 compiled apache is logging client addresses with all
4027 bits set (255.255.255.255). This is the second such problem caused
4028 by gcc 2.8.1 compiler. The first being broken semaphore locking.
4031 *) Updated mime.types to reflect current Internet media types
4032 and include a URL to the registry.
4033 [Manoj Kasichainula, Roy Fielding] PR#2380, 2286, 2246
4035 *) SECURITY: Do a more complete check in mod_include to avoid
4036 an infinite loop of recursive SSI includes. [Marc Slemko] PR#3323
4038 *) Add APACI --suexec-docroot and --suexec-logfile options which can be
4039 used to set the document root directory (DOC_ROOT) and the suexec
4040 logfile (LOG_EXEC), respectively. Additionally the --layout option
4041 was changed to show more information about the suEXEC setup.

4044 *) Added the last two WebDAV status codes of 424 (Failed Dependency)
4045 and 507 (Insufficient Storage) for use by third-party modules.
4048 *) Enabled all of the WebDAV method names for use by third-party
4049 modules, Limit, and Script directives. That includes PATCH,
4050 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
4051 Improved mod_actions.c so that it can use any of the methods
4052 defined in httpd.h. Added ap_method_number_of(method) for
4053 getting the internal method number. [Roy Fielding]

4075 script failed, including the command line used to attempt to execute
4076 the interpreter and the Win32 error code returned. [Marc Slemko]
4078 *) Disable sending of error-notes on a 500 (Internal Server Error) response
4079 since it often includes file path info. Enable sending of error-notes
4080 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
4082 *) http_config.c would respond with 501 (Method Not Implemented) if a
4083 content type handler was specified but could not be found, which
4084 should have been a 500 response. Likewise, mod_proxy.c would responsd
4085 with a 501 if the URI scheme is unrecognized instead of the correct
4086 response of 403 (Forbidden). [Roy Fielding]
4088 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
4089 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
4091 *) Fix in mod_autoindex: for files where the last modified time stamp was
4092 unavailable, an empty string was printed which was 2 bytes short.
4093 The size and description columns were therefore not aligned correctly.

4097 release A17, the child fork() must be replaced by a _rfork().

4100 *) Add the actual server_rec structure of the specific Vhost to the
4101 scoreboard file and avoid a string copy (as well as allow some
4102 further future enhancements). [Harrie Hazewinkel
4103 <harrie.hazewinkel@jrc.it>]
4105 *) Add APACI --permute-module=foo:bar option which can be used to
4106 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
4107 in the Configuration[.apaci] file. Two special and important variants are
4108 supported for the option argument: first BEGIN:foo which permutes module
4109 mod_foo with the begin of the module list, i.e. it `moves' the module to
4110 the begin of the list (gives it lowest priority). And second foo:END
4111 which permutes mod_foo with the end of the module list, i.e. it `moves'
4112 the module to the end of the list (gives it highest priority).

4156 you to override a specific handler. [Marc Slemko]

4160 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074

4163 in mod_auth if we know that we know that no other module can
4164 deal with it. [Marc Slemko]

4181 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
4183 Changes with Apache 1.3.3
4185 *) Added a complete implementation of the Expect header field as
4186 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
4187 response when we already know the final status, which is mighty
4188 useful for PUT responses that result in 302 or 401. [Roy Fielding]
4190 *) Remove extra trailing whitespace from the getline results as part
4191 of the protocol processing, which is extra nice because it works
4192 between continuation lines, is almost no cost in the normal case
4193 of no extra whitespace, and saves memory. [Roy Fielding]
4195 *) Added new HTTP status codes and default response bodies from the
4196 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
4197 HTTP Extension Framework (510) specifications. Did not add the
4198 WebDAV 424 and 425 codes because they are bogus. We don't use any
4199 of these codes yet, but they are now available to 3rd-party modules.

4315 You now must define a BS2000Account name for the server User.
4316 This has fewer security implications than the old approach.
4319 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
4320 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
4321 platform to make the braindead HPUX linker happy. Notice, for the module
4322 DSOs we don't have to use this, because these are loaded manually (and
4323 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

4334 *) Make PrintPath work generically instead of having one version
4335 strictly for OS/2. [Jim Jagielski, Brian Havard]
4337 *) Fix the recently introduced C header file checking: We now use the C
4338 pre-processor pass only (and no longer the complete compiler pass) to
4339 determine whether a C header file exists or not. Because only this way
4340 we're safe against inter-header dependencies (which caused horrible
4341 portability problems). The only drawback is that we now have a CPP
4342 configuration variable which has to be determined first (we do a similar
4343 approach as GNU Autoconf does here). When all fails the user still has
4344 the possibility to override it manually via APACI or src/Configuration.
4345 As a fallback for the header check itself we can directly check the
4346 existance of the file under /usr/include, too.

4379 because our GuessOS is still unaware of Digital UNIX versions and the

4395 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
4397 *) mod_expires will now act on content that is not sent from a file
4398 on disk. Previously it would never add an Expires: header to
4399 any response that did not come from a file on disk; the only
4400 case where it still doesn't (and can't) add one for that type of
4401 content is if you are using a modification date based setting.

4410 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
4413 *) Recognize lowercase _and_ uppercase `uname' results under
4414 SCO OpenServer. [David Coelho <drc@ppt.com>]
4416 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
4417 a common problem of (mis-administrated?) IIS servers, make the apache
4418 proxy immune to these errors (and ignore the duplicates, but log
4419 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
4421 *) The <IfModule and <IfDefine block starting directives now only
4422 allow exactly one argument. Previously, the optional negation
4423 character '!' could be separated by whitespace without a syntax
4424 error being reported, albeit defeating the IfModule functionality
4425 (enclosed directives would ALWAYS be executed). By using the
4426 stricter syntax, these hard-to-track errors can be avoided.
4429 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
4430 cause the standalone FancyIndexing directive to logically OR
4431 into any existing IndexOptions settings rather than wiping
4432 them out. [Ken Coar]
4434 *) Changes in ftp proxy: make URL parsing simpler by using the
4436 + Add display of the "current directory" in cases where it's
4437 different from the supplied path (e.g., ftp://user@host/ lives
4438 in /home/user, not in /, therefore clicking on "../" in the
4439 starting directory might send us to /home/).
4440 + When ftp login fails, (esp. when a user name was part of the
4441 URL already), we now return [401 Unauthorized ] to allow the
4442 browser to pop up an authorization dialog. This makes passwords
4443 slightly less visible (they don't appear in the regular log files)
4444 and implements a functionality that other www proxy servers
4448 *) Triggered by the recent "Via:" header changes, the proxy module would
4449 dump core for replies with invalid headers (e.g., duplicate
4450 "HTTP/1.0 200 OK" lines). These errors are now logged and the
4451 core dump is avoided. Also, broken replies are not cached.
4452 [Martin Kraemer] PR#2914
4454 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
4455 plop gmon.out profile data for each child [Doug MacEachern]
4457 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
4458 config.status script to be immune against arguments with whitespaces.
4459 [Yves Arrouye <yves@apple.com>] PR#2866
4461 *) Replace the inlined information grabbing stuff for the configuration
4462 adjustment feature (no --without-confadjust) with calls to a new helper
4463 script `buildinfo.sh' which is both more flexible and already proofed to
4464 be more robust against platform differences. This mainly fixes the
4465 recently occured ``sed: command garbled: ...'' problems.
4466 [Ralf S. Engelschall] PR#2776, PR#2848

4471 [Ralf S. Engelschall]
4473 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
4474 modules as API functions and we forgot them at the big symbol renaming.

4483 *) Add the ability to do POST requests to the ab benchmarking tool.
4484 [Kurt Sussman <kls@best.com>] PR#2871
4486 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
4487 5 to 10 because there are some users out there who always have 5 to 8
4488 variables in one RewriteRule and had to patch mod_rewrite.h for every
4489 release. So 15 should be now more than enough, even for them. (I never
4490 needed more than 4 in my RewriteRules ;-)
4491 [Ralf S. Engelschall]
4493 *) Make the proxy generate and understand Via: headers
4496 *) Change the proxy to use tables instead of array_headers for
4497 the header lines. [Martin Kraemer]
4499 *) Make sure the config.status file is not overridden when just
4500 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
4502 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
4503 provide a way to trace API changes that add functionality but do
4504 not create a compatibility issue for precompiled modules, etc.
4505 See include/ap_mmn.h for more details. [Randy Terbush]
4507 *) Fix suexec installation under `make install root=xxx' situation.
4508 [Ralf S. Engelschall]
4510 *) Extend the output of the -V switch to include the paths of all
4511 compiled-in configuration files, if they were overridden at
4512 compile time, for least astonishment of the user.
4515 *) When READing a request in ExtendedStatus mode, the "old"
4516 vhost, request and client information is not displayed.
4519 *) STATUS is no longer available. Full status information now
4520 run-time configurable using the ExtendedStatus directive.
4523 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
4524 cpu time attacks) in header parsing. Add ap_overlap_tables(),
4525 a function which can be used to perform bulk update operations
4526 on tables in a more efficient manner. [Dean Gaudet]
4528 *) SECURITY: Added compile-time and configurable limits for
4529 various aspects of reading a client request to avoid some simple
4530 denial of service attacks, including limits on maximum request-line
4531 size (LimitRequestLine), number of header fields (LimitRequestFields),
4532 and size of any one header field (LimitRequestFieldsize). Also added
4533 a configurable directive LimitRequestBody for limiting the size of the
4534 request message body. [Roy Fielding]
4536 *) Make status module aware of DNS and logging states, even if
4537 STATUS not defined. [Jim Jagielski]
4539 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
4541 *) Enhance mod_speling so that CheckSpelling can be used in
4542 <Directory> containers and .htaccess files. [Ken Coar]
4544 *) API: new ap_custom_response() function for hooking into the
4545 ErrorDocument mechanism at runtime [Doug MacEachern]
4547 *) API: new ap_uuencode() function [Doug MacEachern]
4549 *) API: scan_script_header_err_core() now "public" and renamed
4550 ap_scan_script_header_err_core() [Doug MacEachern]
4552 *) The 'status' module will now show the process pid's and their
4553 state even without full STATUS accounting. [Jim Jagielski]
4555 *) Restore the client IP address to the error log messages, this
4556 was lost during the transition from 1.2 to 1.3. Add a new
4557 function ap_log_rerror() which takes a request_rec * and
4558 formats it appropriately. [Dean Gaudet] PR#2661
4560 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
4561 whitespace in input lines -- including within quoted strings.
4563 but leading and trailing whitespace should continue to be
4564 stripped [Martin Kraemer]
4566 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
4567 the ugly use of an env. variable and use command-line args for
4568 alternate $PATH. Make more like advanced 'type's as well.
4571 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
4572 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
4573 <alain.st-denis@ec.gc.ca>] PR#2736
4575 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
4577 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
4578 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
4579 directory was renamed to src/os/os2/ for consistency.
4580 [Brian Havard, Ralf S. Engelschall]
4582 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
4583 files (here modules) against other DSO files (here shared libraries).
4584 This is done by determining a subset of LIBS which can be safely used for
4585 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
4586 disabled for all platforms to avoid problems with this (experimental)
4587 rule. But we provide it now for those people how ran into problems and
4588 want to came out by forcing linking against DSOs.
4589 [Ralf S. Engelschall] PR#2587
4591 *) Fix suEXEC start message: Has to be of `notice' level to really get
4592 printed together with the standard startup message because the `notice'
4593 level is handled special inside ap_log_error() for startup messages.

4603 handling loop so that the connection can be properly closed with
4604 lingering_close, thus avoiding a potential TCP reset that would
4605 cause the client to miss the HTTP error response. [Roy Fielding]
4607 *) One more portability fix for APACI shadow tree support: Swap order of awk
4608 and sed in top-level configure script to avoid sed fails on some
4609 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
4610 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729

4667 the read_request error conditions of URI-too-long (414) and
4668 malformed header fields (400). [Roy Fielding] PR#2646

4671 the TRACE method. This allows apache to TRACE along a chain of proxies
4672 up to a predetermined depth. [Martin Kraemer]
4674 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled

4714 *) Global renaming of C header files to both get rid of conflicts with third
4715 party packages and to again reach consistency:
4716 1. conf.h -> ap_config.h

4720 5. apctype.h -> ap_ctype.h
4721 Backward compatibility files for conf.h and compat.h were created.
4723 *) mod_mmap_static will no longer take action on requests unless at
4724 least one "mmapfile" directive is present in the configuration.
4725 This experimental module has to do some black magic to operate
4726 inside the current API and thus creates side-effects for other
4727 modules under some circumstances.

4740 TestCompile) instead of defining them manually in conf.h based on less
4741 accurate platform definitions. This way we no longer have to fiddle with

4751 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
4752 modules to load their own modules dynamically. This improves mod_perl
4753 and mod_php3 when these modules are loaded dynamically into Apache.
4756 *) Cache a proxied request in the event that the client cancels the

4900 than strcmp() to check for parent directory-ness of an entry. Oh, and
4901 make sure the parent directory (if displayed) is *always* listed first
4902 regardless of the sort key. Overall performance winnage should be good
4903 in CPU time, instruction cache, and memory usage, particularly for large

4915 non-equal to 0. This can be used manually by the user to check the Apache
4916 configuration after editing and is also automatically used by apachectl
4917 on (graceful) restart command to make sure Apache doesn't die on restarts
4918 because of a configuration which is now broken since the last (re)start.
4919 This way `apachectl restart' can be used inside cronjobs without having
4920 to expect Apache to be falling down. Additionally the httpd -t can be run
4921 via `apachectl configtest'.

5061 spawn_child was obsoleted and moved to compat.h
5064 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
5065 programs: ap_spawn_child_err() is used and the Win32 case now uses
5066 CreateProcess() instead of a low-level execl() (which caused problems in
5067 the past under Win32).
5068 [Ralf S. Engelschall]
5070 *) A few cosmetics and trivial enhancements to APXS to make the
5071 generated Makefile more user friendly. [Ralf S. Engelschall]
5073 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5074 was updated to use the normal apache error processing, thereby allowing
5075 proxy errors to be treated by ErrorDocument's as well. For this
5076 purpose, a new module-to-core communication variable "error-notes"
5077 was introduced; the proxy (and possibly other modules) communicates
5078 its error text using this variable. Its content is copied to a new
5079 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5080 The old proxy special error routine ap_proxy_log_uerror()
5081 was replaced by regular ap_log_error() calls, many messages were made

5085 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
5088 *) Transform the configure message "You need root privileges for suEXEC"

5090 ("make") of Apache we can allow, of course. Root privileges are needed
5091 only for the installation step ("make install"). So make sure the

5115 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often

5148 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
5149 [Ben Laurie] PR#2238
5151 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
5152 library), so CGI handling has been changed to use Win32 native handles
5153 instead of C file descriptors.
5154 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5156 *) The proxy cache would store an incorrect content-length in the cached
5157 file copy after a cache update. That resulted in repeated fetching
5158 of the original copy instead of using the cached copy.
5159 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5161 *) The Makefiles assumed that DSO files are build via $(LD). This
5162 is broken for two reasons: First we never defined at least LD=ld
5163 somewhere to make sure this works (it was silently assumed that most Make
5164 provide a built-in LD definition - ARGL!) and second using the generic LD
5165 variable is not the truth. Instead a special variable named LD_SHLIB is
5166 reasonable because although "ld" is usually the default, the command for
5167 building DSO files can be "libtool" or even "cc" on some systems.
5168 [Ralf S. Engelschall]
5170 *) Replace the AddVersionPlatform directive with ServerTokens which
5171 provides for more control over the format of the Server:
5172 header line. SERVER_SUBVERSION is no longer supported;
5173 all module should use the ap_add_version_component()
5174 API function instead. [Jim Jagielski]
5176 *) Support for the NCR MP/RAS 3.0
5177 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
5179 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
5180 not retrieved in src/Configure and thus was not useable.
5181 [Ralf S. Engelschall]
5183 *) Various Makefile consistency cleanups:
5184 - make OSDIR also automatically be relative to src/ like INCDIR
5185 - SUBDIRS is now generated in src/Makefile only and not in
5186 Makefile.config because it is a local define for this location.
5187 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5188 any Makefile but make sure that at least the "-K inline" is kept in
5190 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5191 - updated the dependencies theirself
5192 - removed not existing SHLIB variable from "clean" targets
5193 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5194 already exists and OBJS_PIC are also just plain objects and have not
5195 directly to do with "shared" things. The only difference is that they
5196 contain PIC. So OBJS_PIC is the more canonical name.
5197 - Updated the Makefile-dependency lines for OBJS_PIC
5198 - Removed the Makefile-dependency line in Configure to avoid double
5200 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5201 of xxx.lo as GNU libtool does with its PIC objects
5202 - reduce local complexity in modules Makefile.tmpl by moving the last
5203 existing target "depend" to the generation section in Configure, too.
5204 - removed the historical $(SPACER) which was used in the past together
5205 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5206 is no longer needed.
5207 - force the build and run of the gen_xxx programs under main/ as the
5208 first step before building the objects because it looks cleaner
5209 [Ralf S. Engelschall]
5211 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
5214 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
5217 *) WIN32: Don't force ISAPI headers to finish with \n.
5218 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5220 *) When opening "configuration" files (like httpd.conf, htaccess
5221 and htpasswd), Apache will not allow them to be non-/dev/null
5222 device files. This closes a DoS hole. At the same time,
5223 we use ap_pfopen to open these files to handle timeouts.
5224 [Jim Jagielski, Martin Kraemer]
5226 *) Apache will now log the reason its httpd children exit if they exit
5227 due to an unexpected signal. (It requires a new porting define,
5228 SYS_SIGLIST, which if defined should point to a list of text
5229 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5231 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5232 like WIN32. Before, Win32 CGI's could have had sporadic failures
5233 if a chdir call from one thread was made between another chdir call
5234 and a spawn in another thread. So, for now don't chdir for CGI scripts
5235 in WIN32. The current CGI "spec" is unclear as to whether it's
5236 necessary. Long-term fix is to either serialize the chdir/spawn combo
5237 or use WIN32 native calls to spawn a process. This temp fix was
5238 necessary to remove this as a showstopper for 1.3's release.
5241 *) Cleanup the suEXEC support in APACI and make it more safe:
5242 1. Add big fat hint in INSTALL about risks and to read the
5243 htdocs/manual/suexec.html document before using the suexec-related
5245 2. Make sure the user has at least provided one --suexec-xxxx option
5246 (specifies suEXEC parameters) in addition to --enable-suexec option.
5247 If only --enable-suexec is given APACI stops with a hint to INSTALL
5248 and htdocs/manual/suexec.html documents.
5249 3. Provide two additional --suexec-xxxx options to make the suEXEC
5250 configuration complete (especially for package maintainers who else
5251 had to patch the source tree) by providing ways to configure minimal
5252 UID/GID and safe PATH, too.
5253 [Ralf S. Engelschall]
5255 *) Cleanup of the `configure --shadow' process:
5256 - make sure the configure script creates its temporary files in the
5257 shadow tree to avoid conflicts with parallel configure runs
5258 - removed unnecessary option "-r" from "rm" call for Makefiles
5259 - make sure the configure scripts creates the shadow-wrapper Makefile
5260 only when no shadow trees already exists
5261 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5262 when no more shadow trees exists
5263 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5264 as fast (in the past it needed 70sec, now it runs just 38sec)
5265 - make sure CVS does not complain about the created files
5266 Makefille.<gnutriple> and directories src.<gnutriple>
5267 [Ralf S. Engelschall]
5269 *) Added the ap_add_version_component() API routine and the
5270 AddVersionPlatform core directive. The first allows modules to
5271 declare themselves in the Server response header field value,
5272 augmenting the SERVER_SUBVERSION define in the Configuration file
5273 with run-time settings (more useful in a loadable-module environment).
5274 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5275 into the server version string. [Ken Coar] PR#2056
5277 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5280 *) Emit the "Accept-Range" header for the default handler.
5281 [Brian Behlendorf] PR#1464
5283 *) Add a note to httpd.conf-dist that apache will on some systems fail
5284 to start when the Group # is set to a negative or large positive value.
5287 *) Make sure the module execution order is correct even when some modules
5288 are loaded under runtime (`LoadModule') via the DSO mechanism:
5289 1. The list of loaded modules is now a dynamically allocated one
5290 and not the original statically list from modules.c
5291 2. The loaded modules are now correctly setup by LoadModule for
5292 later use by the AddModule command.
5293 3. When the DSO mechanism for modules is used APACI's `install'
5294 target now enables all created `LoadModule' lines per default because
5295 this is both already expected by the user _and_ needed to avoid
5296 confusion with the next point and reduces the Makefile.tmpl complexity
5297 4. When the DSO mechanism for modules is used, APACI's `install'
5298 target now additionally makes sure the module list is reconstructed
5299 via a complete `ClearModuleList+AddModule...' entry.
5300 5. The support tool `apxs' now also makes sure an AddModule command
5301 is added in addition to the LoadModule command.
5302 6. The modules.c generation was extended to now contain two
5303 comments to make sure no one is confused by the confusing terminology
5304 of loading/linking (we use load=link+load & link=activate instead of
5305 the obvious load=activate & link=link :-( )
5306 This way now there is no longer a difference under execution time between
5307 statically and dynamically linked modules.
5308 [Ralf S. Engelschall]
5310 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
5311 Big Symbol Renaming. [Ralf S. Engelschall]
5313 *) Add a comment to mod_example.c showing the format of a FLAG command
5316 *) Standardized the time format in mod_status to match that of other
5317 places in the code (e.g. DATE_GMT). PR#1551
5319 *) Fix handling of %Z in timefmt strings for those platforms with no time
5320 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5323 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5324 feature compatible with 'UseCanonicalName off' by changing
5325 r->server->server_hostname to ap_get_server_name(). And I changed some
5326 functions which use r->server->port to use ap_get_server_port() instead,
5327 because if there's no Port directive in the config r->server->port is 0.
5330 *) get/set_module_config are trivial enough to be better off inline. Worth
5331 1.5% performance boost. [Dean Gaudet]
5333 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5334 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5337 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5338 the task environment to the unprivileged User id. Otherwise CGI scripts
5339 would have a way to gain super user access. [Martin Kraemer]
5341 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5342 absolute path, only log base name of logging source as is done
5343 in unix. [Martin Kraemer]
5345 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5346 the encoding type from the Accept-Encoding header (if it's there)
5347 and use it in the response, as that's probably what it'll be expecting.
5348 [Ronald.Tschalaer@psi.ch]
5350 *) Fix to mod_alias: translate_alias_redir is dealing with
5351 a URI, not a filename, so the check for drive letters for win32
5352 and emx is not necessary. [Dean Gaudet]
5354 *) WIN32: Allow .cmd as an executable extension.
5355 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
5357 *) Make Apache header files, and some variables, C++ friendly.
5358 [Michael Anderson's <mka@redes.int.com.mx>]
5360 *) Child processes can now "signal" (by exiting with a status
5361 of APEXIT_CHILDFATAL) the parent process to abort and
5362 shutdown the server if the error in the child process was
5363 fatal enough. [Jim Jagielski]
5365 *) mod_autoindex's find_itme() was sensitive to MIME type case.
5366 [Jim Jagielski] PR#2112
5368 *) Make sure the referer_log and agent_log entries in the default httpd.conf

5372 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
5374 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
5377 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5378 Additionally the checks for finding the vendor DSO library were moved
5379 from mod_so.c to Configure because first it needs $PLAT etc. and second
5380 mod_so already uses an abstraction layer and does not fiddle with the
5381 vendor functions itself.
5382 [Jens-Uwe Mager, Ralf S. Engelschall]
5384 *) PORT: Some optimization defines for NetBSD

5387 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
5388 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
5390 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
5391 AIX variants should work fine, too. Even AIX 3.x should work). This is
5392 accomplished by using the free DSO emulation code from Jens-Uwe Mager
5393 which we put into a os/unix/os-dso-aix.c file.

5403 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
5404 is unset (as it is in situations like timeouts) where it is unclear
5405 whether errno is set or not. [Martin Kraemer]
5407 *) Just having APACI's localstatedir is too general and not enough for most
5408 of the systems. 1.3b6 again required manual APACI patches by package
5409 maintainers from RedHat and FreeBSD because for their filesystem layout a
5410 little bit more flexibility in configuring the paths is needed. Hence we
5411 provide three additional configure options (--runtimedir, --logfiledir,
5412 --proxycachedir) which now can be used for more granular adjustments if
5413 --localstatedir is not enough to fit the particular needs. As a nice
5414 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
5415 [Ralf S. Engelschall]
5417 *) Make the install root for "make install" in APACI's Makefile overrideable
5418 by package authors. This way we are even more friendly to package
5419 maintainers (especially Debian and RedHat) who build for the real prefix
5420 via "configure --prefix=/<real>" but use a different local prefix via
5421 "make root=/tmp/apache install" for rolling the package without bristling
5422 the target location on their system.
5423 [Ralf S. Engelschall]
5425 *) Workaround sed limitations in APACI's configure script by now
5426 substituting in chunks of 50 commands (because for instance HPUX's vendor
5427 sed has a limit of max. 98 commands)
5428 [Ralf S. Engelschall] PR#2136
5430 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
5431 [Ralf S. Engelschall] PR#2140
5433 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
5434 RENAMING process because they are defined as pre-processor macros instead
5435 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
5436 [Ralf S. Engelschall]
5438 *) Workaround braindead AWK's when generating ap_config.h: The split() and
5439 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
5440 [Ralf S. Engelschall] PR#2139
5442 *) Various bugfixes and cleanups for the APACI configure script:
5443 o fix IFS handling for _nested_ situation
5444 o fix Perl interpreter search: take first one found instead of last one
5445 o fix DSO consistency check
5446 o print error messages to stderr instead of stdout
5447 o add install-quiet for --shadow situation to Makefile stub
5448 o reduce complexity by avoiding sed-hacks for rule and module list loops
5449 [Ralf S. Engelschall]
5451 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
5453 *) Make sure the input field separator (IFS) shell variable is explicitly
5454 initialized correctly before _every_ `for' loop and also restored after
5455 the loops. [Ralf S. Engelschall]
5457 *) Make sure that "make install" doesn't overwrite the `mime.types' and
5458 `magic' files from an existing Apache installation. Because people often
5459 customize these for own MIME and content types.
5460 [Ralf S. Engelschall]
5462 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
5463 [Peter Galbavy, Ralf S. Engelschall] PR#2109
5465 *) Fix the path to the ScoreBoardFile in the install-config target, too.
5466 [Ralf S. Engelschall] PR#2105
5468 *) Let "configure" clear out the users parameters (provided as shell
5469 variables) to avoid side-effects in "src/Configure" when the user
5470 exported them (which is not needed, but some users do it).
5471 [Ralf S. Engelschall] PR#2101
5473 *) Provide backward compatibility from some old src/Configuration.tmpl
5474 parameter names to the canonical Autoconf-style shell variable names. For
5475 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
5476 but a hint message is displayed. [Ralf S. Engelschall]
5478 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
5479 CGI scripts from an existing Apache installation.
5480 [Ralf S. Engelschall, Jim Jagielski] PR#2084
5482 *) Make `configure --compat' more "compatible" by first
5483 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
5484 second by making sure the "avoid-bristling-suffix" /apache is not
5485 appended to sysconfdir, datadir, localstatedir and includedir when
5486 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
5488 *) NeXT required strdup() in support/logresolve.c
5489 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
5491 *) AIX required sys/select.h in support/ab.c
5492 [Jens Schleusener <Jens.Schleusener@dlr.de>] PR#2081
5494 *) Fix the path to the MimeMagicFile in the install-config target, too.
5495 [Ralf S. Engelschall] PR#2089
5497 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
5499 *) If you start apache with the -S command line option it will dump
5500 out the parsed vhost settings. This is useful for folks trying
5501 to figure out what is wrong with their vhost configuration.
5502 (Other dumps may be added in the future.) [Dean Gaudet]
5504 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
5505 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
5508 *) Because /usr/local/apache is the default prefix the ``configure
5509 --compat'' option no longer has to set prefix, again. This way the
5510 --compat option honors a leading --prefix option. [Lars Eilebrecht]
5512 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
5513 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
5514 to avoid "discard const" warnings. [Ralf S. Engelschall]
5516 *) If a specific handler is set for a file yet the request still
5517 ends up being handled by the default handler, log an error
5518 message before handling it. This catches things such as trying
5519 to use SSIs without mod_include enabled. [Marc Slemko]
5521 *) Fix error logging for the startup case where ap_log_error() still uses
5522 stderr as the target. Now the default log level is honored here, too.
5523 [Ralf S. Engelschall]
5525 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
5526 long" errors when generating the MODULES entry for src/Makefile
5527 [Ben Hyde, Ralf S. Engelschall]
5529 *) Make sure src/Configure doesn't complain about the old directory
5530 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
5532 Changes with Apache 1.3b6
5534 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
5536 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
5537 interface via the similar but proprietary HP/UX shl_xxx-style system
5538 calls. [Ralf S. Engelschall]
5540 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
5541 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
5542 Make. [Ralf S. Engelschall]
5544 *) ++++ THE BIG SYMBOL RENAMING ++++
5545 To avoid symbol clashes with third-party code compiled into the server,
5546 we globally applied the prefix "ap_" to the following classes of
5548 - Apache provided general functions (e.g., ap_cpystrn)
5549 - Public API functions (e.g., palloc, bgets)
5550 - Private functions which we can't make static (because of
5551 cross-object usage) but should be (e.g., new_connection)
5552 For backward source compatibility a new header file named compat.h was
5553 created which provides defines for the old symbol names and can be used
5554 by third-party module authors.
5557 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
5558 problem under SVR4 is that there is no command flag to force the linker
5559 to export the global symbols of the httpd executable therewith they are
5560 available to the DSO's. Instead of problematic hacks like creating a
5561 dummy.so file (containing dummy references to all global symbols) the
5562 httpd binary is linked against, we use a clean trick stolen from Perl 5:
5563 Placing the Apache core code itself into a DSO library named libhttpd.so.
5564 This way the global symbols _HAVE_ to be exported and thus are available
5565 to any manually loaded DSO's under runtime. To reduce the impact to the
5566 user to null we go even further and create a stub httpd executable which
5567 automatically keeps track of the DSO library loading itself and thus
5568 hides the complete mechanism from the user. Although the generation of
5569 this DSO library is automatically triggered for platforms which
5570 essentially need it (mostly all SVR4-derivates) it can be also enabled
5571 manually via the Rule SHARED_CORE. This can be interesting in the future
5572 where we perhaps exploit this libhttpd.so mechanism for providing nifty
5573 features like graceful upgrades, or whatever.
5574 [Ralf S. Engelschall, Martin Kraemer]
5576 *) Build the libraries before building the rest of the tools. [Ben Hyde]
5578 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
5579 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
5580 conventions while "clean" removes only stuff created by "all" targets,
5581 "distclean" additionally removes the stuff from the configuration
5582 process. This way "make distclean" (hence the name) provides a fresh
5583 source tree as it was for distribution.
5584 [Ralf S. Engelschall]
5586 *) Allow top-level (APACI) Makefile to break on build errors
5587 the same way the src/ subtree Makefiles breaks on them by replacing the
5588 initial APACI sed-subdir-display-kludge with a more clean
5589 variable-passing-solution: variable SDP can optionally hold the subdir
5590 prefix which is consistently used for displaying the subdir movement.
5591 This way even the top-level Makefile can stop correctly on errors as the
5592 user expects. [Ralf S. Engelschall]
5594 *) Fixed ordering of argument checks for RewriteBase directive.
5595 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
5597 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
5598 indicating that a module is being compiled for dynamic loading. Also
5599 remove #define IS_MODULE from modules and add SHARED_MODULE define
5600 to the mak/dsp files. [Alexei Kosut]
5602 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
5603 since we are now logging APLOG_WARNING by default. [Roy Fielding]
5605 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
5607 *) Add documentation file and src/Configuration.tmpl entry for the
5608 experimental mod_mmap_static module. Because although it is and marked as
5609 an experimental one it is distributed and thus should be documented and
5610 prepared for configuration the same way as all others modules.
5611 [Ralf S. Engelschall]
5613 *) Add query (-q) option to apxs support tool to be able to manually query
5614 specific settings from apxs. This is needed for instance when you
5615 manually want to access Apache's header files and you need to assemble
5616 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
5617 [Ralf S. Engelschall]
5619 *) Now src/Configure uses a fallback strategy for the shared object support
5620 on platforms where no explicit information is available: If a Perl
5621 installation exists we ask it about its shared object support and if it's
5622 the dlopen-style one we shamelessly guess the compiler and linker flags
5623 for creating shared objects from Perls knowledge. Of course, the user is
5624 warning about what we are doing and informed that he should send us
5625 the guessed flags when they work. [Ralf S. Engelschall]
5627 *) Provide APACI --without-support option to be able to disable the build
5628 and installation of the support tools from the src/support/ area.
5629 Although its useful to have these installed per default we should provide
5630 a way to compile and install without them for backward-compatibility.
5631 [Ralf S. Engelschall]
5633 *) Add of the new APache eXtenSion (apxs) support tool for building and
5634 installing modules into an _already installed_ Apache package through the
5635 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
5636 this approach actually doesn't need the Apache source tree. The
5637 (APACI-installed) server package is enough, because this now includes the
5638 Apache C header files (PREFIX/include) and the new APXS tool
5639 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
5640 module authors to build their Apache modules _OUTSIDE_ the Apache source
5641 tree while avoiding them to fiddle around with the totally platform
5642 dependend way of compiling DSO files. The tool supports all ranges of
5643 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
5644 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
5645 on-the-fly generate a minimalistic Makefile and sample module for the
5646 first step to provide both a quick success event and to demonstrate the
5647 APXS mechanism to module authors. [Ralf S. Engelschall]
5649 *) Fix core dumps in use of CONNECT in proxy.
5650 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
5652 *) Modify the log directives in httpd.conf-dist files to use CustomLog
5653 so that users have examples of how CustomLog can be used.
5656 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
5657 the Apache distribution tree. Until Apache 1.3 there was no real
5658 out-of-the-box batch-capable build and installation procedure for the
5659 complete Apache package. This is now provided by a top-level "configure"
5660 script and a corresponding top-level "Makefile.tmpl" file. The goal is
5661 to provide a GNU Autoconf-style frontend which is capable to both drive
5662 the old src/Configure stuff in batch and additionally installs the
5663 package with a GNU-conforming directory layout. Any options from the old
5664 configuration scheme are available plus a lot of new options for flexibly
5665 customizing Apache. [Ralf S. Engelschall]
5667 *) The floating point ap_snprintf code wasn't threadsafe.
5668 Had to remove the HAVE_CVT macro in order to do threadsafe
5669 calling of the ?cvt() floating point routines. [Dean Gaudet]
5671 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
5673 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
5674 [Jim Jagielski] PR#1901
5676 *) BUG: Configure was using TCC and CC inconsistently. Make sure
5677 Configure knows which CC we are using. [Jim Jagielski]
5679 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
5680 was defined in a parent directory. [Lars Eilebrecht]
5682 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5683 a generic printf-style routine that can call arbitrary output
5684 routines. Use this to replace http_bprintf.c. Add new routines
5685 psprintf(), pvsprintf() which allocate the exact amount of memory
5686 required for a string from a pool. Use psprintf() to clean up
5687 various bits of code which used ap_snprintf()/pstrdup().
5690 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5691 ap_snprintf() has different semantics and formatting codes than
5692 snprintf(). [Dean Gaudet]
5694 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5695 is necessary on at least Solaris where the /etc/rc?.d scripts
5696 are run with these signals ignored, and "SIG_IGN" settings are
5697 maintained across exec().
5698 [Rein Tollevik <reint@sys.sol.no>] PR#2009
5700 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
5701 used instead of lstat() and thus this flag didn't work as expected.
5702 [Rein Tollevik <reint@sys.sol.no>] PR#2010
5704 *) Fix the proxy pass-through feature of mod_rewrite for the case of
5705 existing QUERY_STRING now that mod_proxy was recently changed because of
5706 the new URL parsing stuff. [Ralf S. Engelschall]
5708 *) A few changes to scoreboard definitions which helps gcc generate
5709 better code. [Dean Gaudet]
5711 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
5712 be a signed bitfield. So mark a few bitfields as signed to
5713 ensure correct code. [Dean Gaudet]
5715 *) The default for HostnameLookups was changed to Off, but there
5716 was a problem and it wasn't taking effect. [Dean Gaudet]
5718 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
5721 *) After a SIGHUP the listening sockets in the parent weren't
5722 properly marked for closure on fork().
5723 [Jürgen Keil <jk@tools.de>] PR#2000
5725 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5726 therefore not exposed to %2F -> '/' translations and 2) the request
5727 is a proxy request, so we're not dealing with a local resource anyway.
5728 Without this, the proxy would fail to work for any URL's with
5729 %2f in them (occurs quite often in
5730 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
5732 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
5734 *) Make the shared object compilation command more portable by avoiding
5735 the direct combination of `-c' & `-o' which is not honored by some
5736 compilers like UnixWare's cc. [Ralf S. Engelschall]
5738 *) WIN32: the proxy was creating filenames missing the last four
5739 characters. While this normally doesn't stop anything from
5740 working, it can result in extra collisions.
5741 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
5743 *) Now mod_proxy uses the response string (in addition to the response status
5744 code) from the already used FTP SIZE command to setup the Content-Length
5745 header if available. [Ralf S. Engelschall] PR#1183
5747 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5748 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
5749 name was really too generic, added documentation for this directive to
5750 the mod_proxy.html and corrected the hyperlink to it in the
5751 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
5753 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
5754 faster [Martin Kraemer]
5756 *) Make Configure die when you give it an unknown command switch.
5759 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5760 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5761 and per default compiled support programs have manual pages - just to
5762 document our stuff a little bit more and to be able to do really
5763 Unix-like installations ;-) [Ralf S. Engelschall]
5765 *) Major cleanups to the Configure script to make it and its generated
5766 Makefiles again readable and maintainable: add SRCDIR option, removed
5767 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5768 generated sections, consequently added Makefile headers with inheritance
5769 information, added subdir movement messages for easier following where
5770 the build process currently stays (more verbose then standard Make, less
5771 verbose than GNU make), same style to comments in the Configure script,
5772 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5774 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5775 from the ZeusBench benchmarking program and can be used to determine the
5776 response performance of an Apache installation. This version is
5777 officially licensed with Zeus Technology, Ltd. See the license agreement
5778 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
5779 [Ralf S. Engelschall]
5781 *) API: Various core functions that are definately not part of the API
5782 have been made static, and a few have been marked API_EXPORT. Still
5783 more have been marked CORE_EXPORT and are not intended for general
5784 use by modules. [Doug MacEachern, Dean Gaudet]
5786 *) mod_proxy was not clearing the Proxy-Connection header from
5787 requests; now it does. This did not violate any spec, however
5788 causes poor interactions when you are talking to remote proxies.
5789 [Marc Slemko] PR#1741
5791 *) Various cleanups to the command line interface and manual pages.
5792 [Ralf S. Engelschall]
5794 *) cfg_getline() was not properly handling lines that did not end
5795 with a line termination character. [Marc Slemko] PR#1869, 1909
5797 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5799 *) Clean up some undocumented behavior of mod_setenvif related to
5800 "merging" two SetEnvIf directives when they match the same header
5801 and regex. Document that mod_setenvif will perform comparisons in
5802 the order they appear in the config file. Optimize mod_setenvif by
5803 doing more work at config time rather than at runtime.
5806 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5807 to allow for modules to overrule them and to reduce redefinition
5808 warnings [Jim Jagielski]
5810 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5813 *) Making the hard-coded cross-module function call mime_find_ct() (from
5814 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5815 checking is really called even for proxy requests except for URLs with
5816 HTTP schemes (because there we can optimize by not running the type
5817 checking hooks due to the fact that the proxy gets the MIME Content-type
5818 from the remote host later). This change cleans up mod_mime by removing
5819 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5820 especially unbundles mod_proxy and mod_mime. This way they both now can
5821 be compiled as shared objects and are no longer tied together.
5822 [Ralf S. Engelschall]
5824 *) util.c cleanup and speedup. [Dean Gaudet]
5826 *) API: Clarification, pstrndup() will always copy n bytes of the source
5827 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5829 *) Mark module command_rec and handler_rec structures const so that they
5830 end up in the read-only data section (and are friendlier to systems
5831 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5833 *) Add check to the "Port" directive to make sure the specified
5834 port is in the appropriate range. [Ben Hyde]
5836 *) Performance improvements to invoke_handler().
5837 [Dmitry Khrustalev <dima@bog.msu.su>]
5839 *) Added support for building shared objects even for library-style modules
5840 (which are built from more than one object file). This now provides the
5841 ability to build mod_proxy as a shared object module. Additionally
5842 modules like mod_example are now also supported for shared object
5843 building because the generated Makefiles now no longer assume there is at
5844 least one statically linked module. [Ralf S. Engelschall]
5846 *) API: Clarify usage of content_type, handler, content_encoding,
5847 content_language and content_languages fields in request_rec. They
5848 must always be lowercased; and the strings pointed to shouldn't
5849 be modified (you must copy them to modify them). Fix a few bugs
5850 related to this. [Dean Gaudet]
5852 *) API: Clarification: except for RAW_ARGS, all command handlers can
5853 treat the char * parameters as permanent, and modifiable. There
5854 is no need to pstrdup() them. Clean up some needless pstrdup().
5857 *) Now mod_so keeps track of which module shared objects with which names
5858 are loaded and thus avoids multiple loading and unloading and irritating
5859 error_log messages. [Ralf S. Engelschall]
5861 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5862 environment variable in the apache core. But that tweaking interferes
5863 with mod_setenv. So don't tweak if the user has specified an explicit
5864 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
5866 *) rputs() did not calculate r->sent_bodyct properly.
5867 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
5869 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
5870 name, or left unset if this value is unavailable. Apache was setting
5871 it to the IP address when unavailable.
5872 [Tony Finch <fanf@demon.net>] PR#1925
5874 *) Various improvements to the configuration and build support for compiling
5875 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5876 OSF1 support with GCC and vendor compilers was added. This way shared
5877 object support is now provided out-of-the-box for FreeBSD, Linux,
5878 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5879 [Ralf S. Engelschall]
5881 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5882 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5883 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5885 *) Fix one more special locking problem for RewriteMap programs in
5886 mod_rewrite: According to the documentation of flock(), "Locks are on
5887 files, not file descriptors. That is, file descriptors duplicated
5888 through dup(2) or fork(2) do not result in multiple instances of a lock,
5889 but rather multiple references to a single lock. If a process holding a
5890 lock on a file forks and the child explicitly unlocks the file, the
5891 parent will lose its lock.". To overcome this we have to make sure the
5892 RewriteLock file is opened _AFTER_ the childs were spawned which is now
5893 the case by opening it in the child_init instead of the module_init API
5894 hook. [Ralf S. Engelschall] PR#1029
5896 *) Change to Location and LocationMatch semantics. LocationMatch no
5897 longer lets a single slash match multiple adjacent slashes in the
5898 URL. This change is for consistency with RewriteRule and
5899 AliasMatch. Multiple slashes have meaning in URLs that they do
5900 not have in (some) filesystems. Location on the other hand can
5901 be considered a shorthand for a more complicated regex, and it
5902 does match multiple slashes with a single slash -- which is
5903 also consistent with the Alias directive.

5906 *) Fix bug with mod_mime_magic causing certain files, including files
5907 of length 0, to result in no response from the server.
5910 *) The Configure script now generates src/include/ap_config.h which
5911 contains the set of defines used when Apache is compiled on a platform.
5912 This file can then be included by external modules before including
5913 any Apache header files in case they are being built separately from
5914 Apache. Along with this change, a couple of minor changes were
5915 made to make Apache's #defines coexist peacefully with any autoconf
5916 defines an external module might have. [Rasmus Lerdorf]
5918 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
5919 but without any RewriteXXXXX directives. Here mod_rewrite is given no
5920 chance by the API to initialize its per-server configuration and thus
5921 receives the wrong one from the main server. This is now avoided by
5922 remembering the server together with the config structure while
5923 configuring and later assuming there is no config when we see a
5924 difference between the remembered server and the one calling us.
5925 [Ralf S. Engelschall] PR#1790
5927 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
5928 is automatically disabled under configure time when the dbm_xxx functions
5929 are not available. Second, two heavy source code errors in the DBM
5930 support code were fixed. This makes DBM RewriteMap's usable again after
5931 a long time of brokenness. [Ralf S. Engelschall] PR#1696
5933 *) Now all configuration files support Unix-style line-continuation via
5934 the trailing backslash ("\") character. This enables us to write down
5935 complex or just very long directives in a more readable way. The
5936 backslash character has to be really the last character before the
5937 newline and it has not been prefixed by another (escaping) backslash.

5953 depending on the rev of Solaris and what mixture of modules
5954 are in use. So it has been disabled, and Solaris is back to
5955 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
5956 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
5957 up static content only servers. Or it may fail unpredictably.

5960 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
5963 *) API: Rewrite of absoluteURI handling, and in particular how
5964 absoluteURIs match vhosts. Unless a request is a proxy request, a
5965 "http://host" url is treated as if a similar "Host:" header had been
5966 supplied. This change was made to support future HTTP/1.x protocols
5967 which may require clients to send absoluteURIs for all requests.
5969 In order to achieve this change subtle changes were made to the API. In a
5970 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
5971 that the unmodified uri can be retrieved easily. r->proxyreq is not set
5972 by the core, modules must set it during the post_read_request or
5973 translate_names phase.
5975 Plus changes to the virtualhost test suite for absoluteURI testing.
5977 This fixes several bugs with the proxy proxying requests to vhosts
5978 managed by the same httpd.
5981 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
5982 code from mod_rewrite. The vhost matching is now performed by a

5999 *) API: A new source module main/util_uri.c; It contains a routine
6000 parse_uri_components() and friends which breaks a URI into its component
6001 parts. These parts are stored in a uri_components structure called
6002 parsed_uri within each request_rec, and are available to all modules.
6003 Additionally, an unparse routine is supplied which re-assembles the URI
6004 components back to an URI, optionally hiding the username:password@ part
6005 from ftp proxy requests, and other useful routines. Within the structure,
6006 you find on a ready-for-use basis:
6007 scheme; /* scheme ("http"/"ftp"/...) */
6008 hostinfo; /* combined [user[:password]@]host[:port] */
6009 user; /* user name, as in http://user:passwd@host:port/ */
6010 password; /* password, as in http://user:passwd@host:port/ */
6011 hostname; /* hostname from URI (or from Host: header) */
6012 port_str; /* port string (integer representation is in "port") */
6013 path; /* the request path (or "/" if only scheme://host was given) */
6014 query; /* Everything after a '?' in the path, if present */
6015 fragment; /* Trailing "#fragment" string, if present */
6016 This is meant to serve as the platform for *BIG* savings in
6017 code complexity for the proxy module (and maybe the vhost logic).
6020 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6021 ${map:key}) available for all location where a string is created in
6022 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

6024 possible expansions are consequently usable at all string creation
6025 locations. [Ralf S. Engelschall]
6027 *) Fix initialization of RewriteLogLevel (default now is 0 as documented

6030 completely overridden (default) or completely inherited (when
6031 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6062 type but with a special post-processing for the looked-up value: It
6063 parses it into alternatives according to `|' chars and then only one
6064 particular alternative is chosen randomly (this is an essential
6065 functionality needed for balancing between backend-servers when using
6066 Apache as a Reverse Proxy. The looked up value here is a list of
6067 servers). Second, `int' with the built-in maps named `tolower' and
6068 `toupper' which can be used to map URL parts to a fixed case (this is an
6069 essential feature to fix the case of server names when doing mass
6070 virtual-hosting with the help of mod_rewrite instead of using
6071 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from

6074 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6075 This directive lets Apache adjust the URL in Location-headers on HTTP
6076 redirect responses sent by the remote server. This way the virtually
6077 mapped area is no longer left on redirects and thus by-passed which is
6078 especially essential when running Apache as a reverse proxy.

6227 header files are in the src/include directory. The -Imain -Iap
6228 references in Makefiles have been changed to the simpler -Iinclude
6229 instead. In addition to simplifying the build a little bit, this
6230 also makes it clear when a module is referencing something in a
6231 other than kosher manner (e.g., the proxy including mod_mime.h).
6232 Module-private header files (the proxy, mod_mime, the regex library,
6233 and mod_rewrite) have not been moved to src/include; nor have
6234 the OS-abstraction files. [Ken Coar]

6246 server setting inside vhosts (only an issue when you have no
6247 <Directory> or other section containing an Options that affects

6264 an internal redirect occured. Such redirects occur, for example,
6265 when processing a DirectoryIndex match. [Dean Gaudet]
6267 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6268 of the key and value. But in many cases this is not required
6269 because the key/value is a constant, or the value has been built
6270 by pstrcat() or other similar means. New routines table_addn,
6271 table_mergen, and table_setn have been added to the API, these
6272 routines do not pstrdup() their arguments. The core code and
6273 standard modules were changed to take advantage of these routines.
6274 The resulting server is up to 20% faster in some situations.
6276 Note that it is easy to get code subtly wrong if you pass a key/value
6277 which is in a pool other than the pool of the table. The only
6278 safe thing to do is to pass key/values which are in the pool of
6279 the table, or in one of the ancestors of the pool of the table.
6280 i.e. if the table is part of a subrequest, a value from the main
6281 request's pool is OK since the subrequest pool is a sub_pool of the
6282 main request's pool (and therefore has a lifespan at most as long as
6283 the main pool). There is debugging code which can detect improper
6284 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.

6287 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
6288 which don't exist on disk more gracefully; handles vhosts properly.
6289 Update documentation to reflect the code -- if there's no
6290 MimeMagicFile directive then the module is not enabled.
6293 *) PORT: Some older *nix dialects cannot automatically start scripts
6294 which begin with a #! interpreter line (the shell starts the scripts
6295 appropriately on these platforms). Apache now supports starting of

6300 *) API: "typedef array_header table" removed from alloc.h, folks should
6301 have been writing to use table as if it were an opaque type, but even
6302 some standard modules got this wrong. By changing the definition
6303 to "typedef struct table table" module authors will receive compile
6304 time warnings that they're doing the wrong thing. This change
6305 facilitates future changes with more sophisticated table
6306 structures. Specifically, module authors should be using table_elts()
6307 to get access to an array_header * for the table. [Dean Gaudet]

6315 *) For clarity the following compile time definition was changed:
6317 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6319 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6320 and not be a general notice that the OS has mmap(). Now the
6321 HAVE_MMAP/SHMGET #defines strictly are informational that the
6322 OS has that method of shared memory; the type to use for
6323 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6324 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6325 determine if shared memory is available and allows Apache
6326 to determine the best method to use for the scoreboard.

6385 insulate them against duplicate calls if they get included through
6386 multiple paths (e.g., in .c files as well as other .h files).
6389 *) The libap routines now have a header file for their prototypes,
6390 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
6392 *) mod_autoindex with a plaintext header file would emit the <PRE>
6393 start-tag before the HTML preamble, rather than after the preamble
6394 but before the header file contents. [John Van Essen <jve@gamers.org>]
6397 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6398 only an issue on systems without a MAXDNAME define or where
6399 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6401 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6402 is used to read various types of files such as htaccess and
6403 htpasswd files. [Marc Slemko]
6405 *) SECURITY: Ensure that the buffer returned by ht_time is always
6406 properly null terminated. [Marc Slemko]
6408 *) The "Connection" header could be sent back with multiple "close"
6409 tokens. Not an error, but a waste.
6410 [Ronald.Tschalaer@psi.ch] PR#1683
6412 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
6413 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
6415 *) "basic" auth needs a case-insensitive comparison.
6416 [Ronald.Tschalaer@psi.ch] PR#1666
6418 *) For maximum portability, the environment passed to CGIs should
6419 only contain variables whose names match the regex
6420 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
6421 underscores over any character outside the regex. This
6422 affects HTTP_* variables, in a way that should be backward
6423 compatible for all the standard headers; and affects variables
6424 set with SetEnv/BrowserMatch and similar directives.
6427 *) mod_speling returned incorrect HREF's when an ambigous match
6428 was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)
6429 [robinton@amtrash.comlink.de (Soeren Ziehe), Martin Kraemer]

6435 *) PORT: Fix problem killing children when terminating. Allow ^C
6436 to shut down the server. [Brian Havard]

6439 no need to do it before calling. Clean up a few cases.
6440 [Marc Slemko, Dean Gaudet]

6455 *) WIN32: Fix a call to os_canonical_filename so it doesn't try to
6456 mess with fake filenames. This fixes proxy caching on
6459 *) SECURITY: General mod_include cleanup, including fixing several
6460 possible buffer overflows and a possible infinite loop.
6461 [Dean Gaudet, Marc Slemko]
6463 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6464 including fixing a possible buffer overflow. [Dean Gaudet]
6466 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
6467 (connections are not dropped). Code can handle graceful restarts
6468 (but there is as yet no way to signal this to Apache). Various
6469 other cleanups. [Paul Sutton]
6471 *) The aplog_error changes specific to 1.3 introduced a buffer
6472 overrun in the (now legacy) log_printf function. Fixed.
6475 *) mod_digest didn't properly deal with proxy authentication. It
6476 also lacked a case-insensitive comparision of the "Digest"
6477 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
6479 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
6481 *) A few cleanups in mod_info to make it thread-safe, and remove an
6482 off-by-5 bug that could hammer \0 on the stack. [Dean Gaudet]
6484 *) no2slash() was O(n^2) in the length of the input. Make it O(n).

6488 ap_cpystrn() for performance and functionality reasons.
6489 Located in libap.a. [Jim Jagielski]
6491 *) table_set() and table_unset() did not deal correctly with

6506 alloc.c (affects win32 only). [Ben Hyde]
6508 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
6510 *) send_fd_length() did not calculate total_bytes_sent properly.
6511 [Ben Reser <breser@regnow.com>] PR#1366
6513 *) The bputc() macro was not properly integrated with the chunking
6514 code; in many cases modules using bputc() could cause completely
6515 bogus chunked output. (Typically this will show up as problems
6516 with Internet Explorer 4.0 reading a page, but other browsers
6517 having no problem.) [Dean Gaudet]
6519 *) Create LARGE_WRITE_THRESHOLD define which determines how many
6520 bytes have to be supplied to bwrite() before it will consider
6521 doing a writev() to assemble multiple buffers in one system
6522 call. This is critical for modules such as mod_include,
6523 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
6524 strings in some cases. The result would be extra effort
6525 setting up writev(), and in many cases extra effort building
6526 chunks. The default is 31, it can be overriden at compile
6529 *) Move the gid switching code into the child so that log files
6530 and pid files are opened with the root gid.
6531 [Gregory A Lundberg <lundberg@vr.net>]

6534 instead of counting control characters.
6535 [Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340
6537 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
6538 so the functionality is available to applications other than the
6539 server itself (like the src/support tools). [Ken Coar]
6541 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
6542 the libap consolidation work. [Ken Coar]
6544 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
6545 useful, and isn't what the standards require. Now it returns 0
6546 and writes nothing. [Dean Gaudet]
6548 *) When an error occurs in fcntl() locking suggest the user look up
6549 the docs for LockFile. [Dean Gaudet]
6551 *) Eliminate some dead code from writev_it_all().
6552 [Igor Tatarinov <tatarino@prairie.NoDak.edu>]
6554 *) mod_autoindex had an fread() without checking the result code.
6555 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"
6556 (note the missing closing paren) properly. [Dean Gaudet]
6558 *) It appears the "257th byte" bug (see
6559 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
6560 at the 256th byte as well. Fixed. [Dean Gaudet]

6592 *) WIN32: Cure file leak in CGIs. [Peter Tillemans <pti@net4all.be>] PR#1523
6594 *) proxy_ftp: the directory listings generated by the proxy ftp module
6595 now have a title in which the path components are clickable and allow
6596 quick navigation to the clicked-on directory on the currently listed
6597 ftp server. This also fixes a bug where the ".." directory links would
6598 sometimes refer to the wrong directory. [Martin Kraemer]

6613 *) WIN32: Work around brain-damaged spawn calls that can't deal
6614 with spaces and slashes. [Ben Laurie]
6616 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
6617 The problem was that certain undocumented environment variables
6618 needed for sockets to work under Win32 were not being passed.

6635 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
6636 This turns out to be a bug in Winsock - select() doesn't always
6637 return the correct status. [Ben Laurie]
6639 *) Directives owned by http_core can now use the new check_cmd_context()
6640 routine to ensure that they're not being used within a container
6641 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
6643 *) PORT: Recent changes made it necessary to add explicit prototype
6644 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
6646 *) It was necessary to distinguish between resources which are
6647 allocated in the parent, for cleanup in the parent, and resources
6648 which are allocated in each child, for cleanup in each child.
6649 A new pool was created which is passed to the module child_init
6650 and child_exit functions; modules are free to register per-child
6651 cleanups there. This fixes a bug with reliable piped logs.
6654 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
6655 unless it was also doing FancyIndexes, but it displayed the
6656 HeaderName file at the top under all circumstances. It now shows
6657 the ReadmeName file for simple indices, too, as it should.
6660 *) http_core was mmap()ing even in cases where it wasn't going to
6661 read the file. [Ben Hyde <bhyde@gensym.com>]
6663 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
6664 Now the rewriting engine (the heart of mod_rewrite) is organized more
6665 straight-forward, first time well documented and reduced to the really
6666 essential parts. All redundant cases were stripped off and processing now
6667 is the same for both per-server and per-directory context with only a
6668 minimum difference (the prefix stripping in per-dir context). As a
6669 side-effect some subtle restrictions and two recently discovered problems
6670 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
6671 context and restrictions on the substitution URL on redirects.
6672 Additionally some minor source cleanups were done.

6827 Changes with Apache 1.3b2 (there is no 1.3b1)
6829 *) TestCompile was not passing $LIBS [Dean Gaudet]
6831 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6834 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6835 rudimentary memory debugger which can be used on live servers with
6836 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6837 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6838 and free() for each object. This is far more expensive and should
6839 only be used for testing with tools such as Electric Fence and
6840 Purify. See main/alloc.c for more details. [Dean Gaudet]
6842 *) Configure uses a sh trap and didn't set its exitcode properly.
6843 [Dean Gaudet] PR#1159
6845 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6846 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6847 From a given ip:port, regardless what the Host: header is, you can
6848 only reach the vhosts defined on that ip:port. The precedence of
6849 vhosts was reversed to match other precedences in the config --
6850 the earlier vhosts override the later vhosts. All vhost matching was
6851 moved into http_vhost.[ch]. [Dean Gaudet]
6853 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6854 be used for whatever reason is appropriate (i.e. format() warnings
6855 for printf style functions). Both are enabled only with
6856 gcc >= 2.7.x (so that we have fewer support issues with older
6857 versions). [Dean Gaudet]
6859 *) Fix support for Proxy Authentication (we were testing the response
6860 status too early). [Marc Slemko]

6869 *) When booting, apache will now detach itself from stdin, stdout,

6871 files have been read so you will be able to see initial error
6872 messages. After that all errors are logged in the error_log.
6873 This makes it more convenient to start apache via rsh, ssh,

6895 *) RedirectMatch was not properly escaping the result (PR#1155). Also
6896 "RedirectMatch /advertiser/(.*) $1" is now permitted.
6899 *) mod_include now uses symbolic names to check for request success
6900 and return HTTP errors, and correctly handles all types of
6901 redirections (previously it only did temporary redirect correctly).

6922 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
6923 bytes before writing, but it will never split a log entry across a
6924 buffer boundary. [Dean Gaudet]
6926 *) API: the short_score record has been split into two pieces, one which
6927 the parent writes on, and one which the child writes on. As part of
6928 this change the get_scoreboard_info() function was removed, and
6929 scoreboard_image was exported. This change fixes a race condition
6930 in file based scoreboard systems, and speeds up changes involving the
6931 scoreboard in earlier 1.3 development. [Dean Gaudet]
6933 *) API: New register_other_child() API (see http_main.h) which allows
6934 modules to register children with the parent for maintenance. It
6935 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
6937 *) API: New piped_log API (see http_log.h) which implements piped logs,
6938 and will use register_other_child to implement reliable piped logs
6939 when it is available. The reliable piped logs part can be disabled
6940 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
6941 logs is only available on Unix. [Dean Gaudet]
6943 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
6944 meets_conditions(). This allows conditional HTTP selection to be
6945 handled separately from the storing of the header fields, and provides
6946 the ability for CGIs to set their own ETags for conditional checking.
6947 [Ken Coar, Roy Fielding] PR#895
6949 *) Changes to mod_log_config to allow naming of format strings.
6950 Format nicknames are defined with "LogFormat fmt nickname", and can
6951 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
6954 *) New module, "mod_speling", which can help find files even when
6955 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
6957 *) API: New function child_terminate() triggers the child process to
6958 exit, while allowing the child finish what it needs to for the
6959 current request first.
6960 [Doug MacEachern, Alexei Kosut]
6962 *) Windows now defaults to using full status reports with mod_status.
6963 [Alexei Kosut] PR #1094
6965 *) *Really* disable all mod_rewrite operations if the engine is off.
6966 Some things (like RewriteMaps) were checked/performed even if they
6967 weren't supposed to be. [Ken Coar] PR #991
6969 *) Implement a new timer scheme which eliminates the need to call alarm() all
6970 the time. Instead a counter in the scoreboard for each child is used to
6971 show when the child has made forward progress. The parent samples this
6972 counter every scoreboard maintenance cycle, and issues SIGALRM if no
6973 progress has been made in the timeout period. This reduces the static
6974 request best-case syscall count to 22 from 29. This scheme is only
6975 used by systems with memory-based scoreboards. [Dean Gaudet]
6977 *) The proxy now properly handles CONNECT requests which are sent
6978 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
6980 *) A script called apachectl has been added to the support
6981 directory. This script allows you to do things such as
6982 "apachectl start" and "apachectl restart" from the command
6985 *) Modules and core routines are now put into libraries, which
6986 simplifies the link line tremendously (among other advantages).
6989 *) Some of the MD5 names defined in Apache have been renamed to have
6990 an `ap_' prefix to avoid conflicts with routines supplied by
6991 external libraries. [Ken Coar]
6993 *) Removal of mod_auth_msql.c from the distribution. There are many
6994 other options for databases today. Rather than offer one option,
6995 offer none at this time. mod_auth_msql and other SQL database
6996 authentication modules can be found at the Apache Module Registry.
6997 http://modules.apache.org/ It would be nice to offer a generic
6998 mod_auth_sql option in the near future.
7000 *) PORT: BeOS support added [Alexei Kosut]
7002 *) Configure no longer accepts the -make option, since it creates
7003 Makefile on the fly based on Makefile.tmpl and Configuration.
7005 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7006 of forcibly killing off all its processes and exiting without
7007 cleaning up. [Alexei Kosut]
7009 *) API: A new field in the request_rec, r->mtime, has been added to
7010 avoid gratuitous parsing of date strings. It is intended to hold
7011 the last-modified date of the resource (if applicable). An
7012 update_mtime() routine has also been added to advance it if
7013 appropriate. [Roy Fielding, Ken Coar]
7015 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7016 deny access to the directory with a HTTP_FORBIDDEN. The previous
7017 behavior was to ignore the htaccess file if it could not be read.
7018 This change may make some setups with unreadable htaccess files
7019 stop working. [Marc Slemko] PR#817
7021 *) Add aplog_error() providing a mechanism to define levels of
7022 verbosity to the server error logging. This addition also provides
7023 the ability to log errors using syslogd. Error logging is configurable
7024 on a per-server basis using the LogLevel directive. Conversion
7025 of log_*() in progress. [Randy Terbush]
7027 *) Further enhance aplog_error() to not log filename, line number, and
7028 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7030 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7031 converted to long ones. Backslashes are converted to forward
7032 slashes. Case is converted to lower. Parts of URLs that do not
7033 correspond to files are left completely alone. [Ben Laurie]
7035 *) PORT: 2 new OSs added to the list of ports:
7036 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7037 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7039 *) Add the server version (SERVER_VERSION macro) to the "server
7040 configured and running" entry in the error_log. Also build an
7041 object file at link-time that contains the current time
7042 (SERVER_BUILT global const char[]), and include that in the
7045 *) Set r->headers_out when sending responses from the proxy.
7046 This fixes things such as the logging of headers sent from
7047 the proxy. [Marc Slemko] PR#659
7049 *) support/httpd_monitor is no longer distributed because the
7050 scoreboard should not be file based if at all possible. Use
7051 mod_status to see current server snapshot.
7053 *) (set_file_slot): New function, allowing auth directives to be
7054 independent of the server root, so the server documents can be
7055 moved to a different directory or machine more easily.
7056 [David J. MacKenzie]
7058 *) If no TransferLog is given explicitly, decline
7059 to log. This supports coexistence with other logging modules,
7060 such as the custom one that UUNET uses. [David J. MacKenzie]
7062 *) Check for titles in server-parsed HTML files.
7063 Ignore leading newlines and returns in titles. The old behavior
7064 of replacing a newline after <title> with a space causes the
7065 title to be misaligned in the listing. [David J. MacKenzie]
7067 *) Change mod_cern_meta to be configurable on a per-directory basis.
7068 [David J. MacKenzie]
7070 *) Add 'Include' directive to allow inclusion of configuration
7071 files within configuration files. [Randy Terbush]
7073 *) Proxy errors on connect() are logged to the error_log (nothing
7074 new); now they include the IP address and port that failed
7075 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7077 *) Various architectures now define USE_MMAP_FILES which causes
7078 the server to use mmap() for static files. There are two
7079 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7080 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7081 number of bytes written in one cycle from a single mmap()d object,
7082 default 32768). [Dean Gaudet]
7084 *) API: Added post_read_request API phase which is run right after reading
7085 the request from a client, or right after an internal redirect. It is
7086 useful for modules setting environment variables that depend only on
7087 the headers/contents of the request. It does not run during subrequests
7088 because subrequests inherit pretty much everything from the main
7089 request. [Dean Gaudet]
7091 *) Added mod_unique_id which is used to generate a unique identifier for
7092 each hit, available in the environment variable UNIQUE_ID.
7095 *) init_modules is now called after the error logs have been opened. This
7096 allows modules to emit information messages into the error logs.
7099 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7100 information for case where proxy module is not available. [Marc Slemko]
7102 *) PORT: Apache has need for mutexes to serialize its children around
7103 accept. In prior versions either fcntl file locking or flock file
7104 locking were used. The method is chosen by the definition of
7105 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7106 and FLOCK for flock(). New options have been added:
7107 - SYSVSEM to use System V style semaphores
7108 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7109 - USLOCK to use IRIX uslock
7110 Based on timing various techniques, the following changes were made
7112 - Linux 2.x uses flock instead of fcntl
7113 - Solaris 2.x uses pthreads
7114 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7115 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7116 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7117 Martijn Koster <m.koster@pobox.com>]
7119 *) PORT: The semantics of accept/select make it very desirable to use
7120 mutexes to serialize accept when multiple Listens are in use. But
7121 in the case where only a single socket is open it is sometimes
7122 redundant to serialize accept(). Not all unixes do a good job with
7123 potentially dozens of children blocked on accept() on the same
7124 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7125 the server will avoid serialization when listening on only one socket,
7126 and use serialization when listening on multiple sockets.
7127 [Dean Gaudet] PR#467
7129 *) Configure changes: TestLib replaced by TestCompile, which has
7130 some additional capability (such as doing a sanity check of
7131 the compiler and flags selected); the version of Solaris is now
7132 available via the #define value of SOLARIS2; IRIX n32bit libs
7133 now supported and selectable by new Configuration Rule: IRIXN32;
7134 We no longer default to -O2 optimization. [Jim Jagielski]
7136 *) Updated Configure: Configuration now uses AddModule to specify
7137 module source or binary file location, relative to src directory.
7138 Modules can be dropped into modules/extra, or in their own
7139 directory, and modules can come with a Makefile or Configure can
7140 create one. Modules can add compiler or library information to
7141 generated Makefiles. [Paul Sutton]
7143 *) Source core re-organisation: distributed modules are now in
7144 modules/standard. All other source code is in main. OS-specific
7145 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7147 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7150 *) Fix another long-standing bug in sub_req_lookup_file where it would
7151 happily skip past access checks on subdirectories looked up with
7152 relative paths. (It's used by mod_dir, mod_negotiation,
7153 and mod_include.) [Dean Gaudet]
7155 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7156 N is the number of <Directory> sections, and M is the number of
7157 components in the filename of an object.
7159 To achieve this optimization the following config changes were made:
7160 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7161 <Files>s, and <Location>s now treat a slash as a special
7162 character. For example "/home/*/public_html" previously would
7163 match "/home/a/andrew/public_html", now it only matches things
7164 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7165 - It's possible now to use [] wildcarding in <Directory>, <Files>
7167 - Regex <Directory>s are applied after all non-regex <Directory>s.
7171 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7172 and corrupted paths. [Dean Gaudet]
7174 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7175 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7176 be accessed now via backreferences $1..$9 in RewriteConds test-against
7177 strings in addition to RewriteRules subst string. Second the grouped
7178 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7179 via backreferences %1..%9 both in following RewriteCond test-against
7180 strings and RewriteRules subst string. This provides maximum flexibility
7181 through the use of backreferences.
7182 Additionally the rewriting engine was cleaned up by putting common
7183 code to the new expand_backrefs_inbuffer() function.
7184 [Ralf S. Engelschall]
7186 *) When merging the main server's <Directory> and <Location> sections into
7187 a vhost, put the main server's first and the vhost's second. Otherwise
7188 the vhost can't override the main server. [Dean Gaudet] PR#717
7190 *) The <Directory> code would merge and re-merge the same section after
7191 a match was found, possibly causing problems with some modules.
7194 *) ip-based vhosts are stored and queried using a hashing function, which
7195 has been shown to improve performance on servers with many ip-vhosts.
7196 Some other changes had to be made to accommodate this:
7197 - the * address for vhosts now behaves like _default_
7198 - the matching process now is:
7199 - match an ip-vhost directly via hash (possibly matches main
7201 - if that fails, just pretend it matched the main server
7202 - if so far only the main server has been matched, perform
7203 name-based lookups (ServerName, ServerAlias, ServerPath)
7204 *only on name-based vhosts*
7205 - if they fail, look for _default_ vhosts
7206 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7208 *) dbmmanage overhaul:
7209 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7210 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7211 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7212 - provide better seed for rand
7213 - prompt for password as per getpass(3) (turn off echo, read from
7215 - use "newstyle" crypt based on $Config{osname} ($^O)
7216 - will not add a user if already in database, use new `update' command
7218 - added `check' command to check a users' password
7219 - added `import' command to convert existing password text-files or
7220 dbm files exported with `view'
7221 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7224 *) Added psocket() which is a pool form of socket(), various places within
7225 the proxy weren't properly blocking alarms while registering the cleanup
7226 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7227 was a bug where the client socket was being close()d twice due a still
7228 registered cleanup. [Dean Gaudet]
7230 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7233 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7234 [Jason Venner <jason@idiom.com>] PR#667
7236 *) Enable ``=""'' for RewriteCond directives to match against
7237 the empty string. This is the preferred way instead of ``^$''.
7238 [Ralf S. Engelschall]
7240 *) Fixed an infinite loop in mod_imap for references above the server root
7241 [Dean Gaudet] PR#748
7243 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7244 SendBufferSize, so that the TCP window can be set appropriately
7245 for LFNs. [Phillip A. Prindeville]
7247 *) mod_browser has been replaced by the more general mod_setenvif
7248 (courtesy of Paul Sutton). BrowserMatch* directives are still
7249 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7250 UnSetEnvIfZero directives. [Ken Coar]
7252 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7253 order for remote_host to be set (for logging, or for the env var
7254 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7257 *) mod_access overhaul:
7258 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7259 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7260 - Critical path was sped up by pre-computing a few things at config time.
7261 - The undocumented syntax "allow user-agents" was removed,
7262 the replacement is "allow from env=foobar" combined with mod_browser.
7263 - When used with hostnames it now forces a double-reverse lookup
7264 no matter what the directory settings are. This double-reverse
7265 doesn't affect any of the other routines that use the remote
7266 hostname. In particular it's still passed to CGIs and the log
7267 without the double-reverse check. Related PR#860.
7270 *) When a large bwrite() occurs (larger than the internal buffer size),
7271 while there is already something in the buffer, apache will combine
7272 the large write and the buffer into a single writev(). (This is
7273 in anticipation of using mmap() for reading files.)
7276 *) In obscure cases where a partial socket write occurred while chunking,
7277 Apache would omit the chunk header/footer on the next block. Cleaned
7278 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7279 a bug where a long pause in DNS lookups could cause the last packet
7280 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7282 *) API: Added child_exit function to module structure. This is called
7283 once per "heavy-weight process" just before a server child exit()'s
7284 e.g. when max_requests_per_child is reached, etc.
7285 [Doug MacEachern, Dean Gaudet]
7287 *) mod_include cleanup showed that handle_else was being used to handle
7288 endif. It didn't cause problems, but it was cleaned up too.
7291 *) mod_cern_meta would attempt to find meta files for the directory itself
7292 in some cases, but not in others. It now avoids it in all cases.
7295 *) mod_mime_magic would core dump if there was a decompression error.
7296 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7298 *) PORT: some variants of DGUX require -lsocket -lnsl

7301 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7302 by the various fields (name, size, et cetera), either in ascending
7303 or descending order. Just click on the column header. [Ken Coar]
7305 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7306 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7307 the relatively safe direction. [Dean Gaudet] PR#344
7309 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7310 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7312 *) child_main avoids an unneeded call to select() when there is only one
7313 listening socket. [Dean Gaudet]
7315 *) In the event that the server is starved for idle servers it will
7316 spawn 1, then 2, then 4, ..., then 32 servers each second,
7317 doubling each second. It'll also give a warning in the errorlog
7318 since the most common reason for this is a poor StartServers
7319 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7320 the maximum. [Dean Gaudet]
7322 *) Apache now provides an effectively unbuffered connection for
7323 CGI scripts. This means that data will be sent to the client
7324 as soon as the CGI pauses or stops output; previously, Apache would
7325 buffer the output up to a fixed buffer size before sending, which
7326 could result in the user viewing an empty page until the CGI finished
7327 or output a complete buffer. It is no longer necessary to use an
7328 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7329 in a language that by default does buffering (e.g. perl) this
7330 shouldn't have a detrimental effect on performance.
7332 "nph-" CGIs, which formerly provided a direct socket to the client
7333 without any server post-processing, were not fully compatible with
7334 HTTP/1.1 or SSL support. As such they would have had to implement
7335 the transport details, such as encryption or chunking, in order
7336 to work properly in certain situations. Now, the only difference
7337 between nph and non-nph scripts is "non-parsed headers".

7344 Changes with Apache 1.3a1
7346 *) Added another Configure helper script: TestLib. It determines
7347 if a specified library exists. [Jim Jagielski]
7349 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
7350 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
7353 *) PORT: Some architectures use size_t for various lengths in network
7354 functions such as accept(), and getsockname(). The definition
7355 NET_SIZE_T is used to control this. [Dean Gaudet]
7357 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
7358 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
7359 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]

7362 [Igor N Kovalenko <infoh@mail.wplus.net>]
7364 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7365 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7366 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

7399 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
7400 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
7401 URLs, fixed rewritelog(), fixed forced response code handling on
7402 redirects from within .htaccess files, disabled pipe locking under
7403 braindead SunOS 4.1.x, allow env variables to be set even on rules with
7404 no substitution, bugfixed situations where HostnameLookups is off, made
7405 mod_rewrite more thread-safe for NT port and fixed problem when creating
7406 an empty query string via "xxx?".
7407 This update also removes the copyright of Ralf S. Engelschall,
7408 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
7409 exclusively copyrighted by the Apache Group now. This happened because
7410 the author now has gifted mod_rewrite exclusively to the Apache Group and
7411 no longer maintains an external version.

7428 *) Configure fixed to correctly propagate user-selected options and
7429 settings (such as CC and OPTIM) to Makefiles other than
7430 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
7432 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
7433 directory indices to start with the contents of the HeaderName file
7434 if there is one. If there isn't one, the behaviour is unchanged.
7435 [Ken Coar, Roy Fielding, Andrey A. Chernov]
7437 *) WIN32: Modules can now be dynamically loaded DLLs using the
7438 LoadModule/LoadFile directives. Note that module DLLs must be
7439 compiled with the multithreaded DLL version of the runtime library.
7440 [Alexei Kosut and Ben Laurie]
7442 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
7443 This allows the admin to completely remove automatic indexing
7444 from the server, while still supporting the basic functions of
7445 trailing-slash redirects and DirectoryIndex files. Note that if
7446 you're carrying over an old Configuration file and you use directory
7447 indexing then you'll want to add:
7449 Module autoindex_module mod_autoindex.o
7451 before mod_dir in your Configuration. [Dean Gaudet]
7453 *) popendir/pclosedir created to properly protect directory scanning.
7454 [Dean Gaudet] PR#525
7456 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
7457 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
7458 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
7461 *) The AccessFileName directive can now take more than one filename.
7462 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7464 *) The new mod_mime_magic can be used to "magically" determine the type
7465 of a file if the extension is unknown. Based on the unix file(1)
7466 command. [Ian Kluft <ikluft@cisco.com>]
7468 *) We now determine and display the time spent processing a
7469 request if desired. [Jim Jagielski]
7471 *) mod_status: PID field of "dead" child slots no longer displays
7472 main httpd process's PID. [Jim Jagielski]
7474 *) Makefile.nt added - to build all the bits from the command line:
7475 nmake -f Makefile.nt
7476 Doesn't yet work properly. [Ben Laurie]
7478 *) Default text of 404 error is now "Not Found" rather than the
7479 potentially misleading "File Not Found". [Ken Coar]
7481 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
7482 for the net if we require people that actually need this data to
7483 enable it. [Linus Torvalds]
7485 *) directory_walk() is an expensive function, keep a little more state to
7486 avoid needless string counting. Add two new functions make_dirstr_parent
7487 and make_dirstr_prefix which replace all existing uses of make_dirstr.
7488 The new functions are a little less general than make_dirstr, but
7489 work more efficiently (less memory, less string counting).
7492 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
7493 to LDFLAGS) to avoid complications with lex rules in make files.
7494 [Dean Gaudet] PR#372
7496 *) run_method optimized to avoid needless scanning over NULLs in the
7497 module list. [Dean Gaudet]
7499 *) Revamp of (unix) scoreboard management code such that it avoids
7500 unnecessary traversals of the scoreboard on each hit. This is
7501 particularly important for high volume sites with a large
7502 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
7503 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
7504 httpd.h. [Dean Gaudet]
7506 *) In configurations using multiple Listen statements it was possible for
7507 busy sockets to starve other sockets of service. [Dean Gaudet]
7509 *) Added hook so standalone_main can be replaced at compile time
7510 (define STANDALONE_MAIN)
7513 *) Lowest-level read/write functions in buff.c will be replaced with
7514 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
7515 compile time. The default sfio discipline will behave as apache
7516 would without sfio compiled in.
7519 *) Enhance UserDir directive (mod_userdir) to accept a list of
7520 usernames for the 'disable' keyword, and add 'enable user...' to
7521 selectively *en*able userdirs if they're globally disabled.
7524 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
7525 will work with Netscape dbm files. (dbmmanage will probably not
7526 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
7528 *) Add a ListenBacklog directive to control the backlog parameter
7529 passed to listen(). Also change the default to 511 from 512.
7532 *) API: A new handler response DONE which informs apache that the
7533 request has been handled and it can finish off quickly, similar to
7534 how it handles errors. [Rob Hartill]
7536 *) Turn off chunked encoding after sending terminating chunk/footer
7537 so that we can't do it twice by accident. [Roy Fielding]
7539 *) mod_expire also issues Cache-Control: max-age headers.
7542 *) API: Added kill_only_once option for free_proc_chain so that it won't
7543 aggressively try to kill off specific children. For fastcgi.
7544 [Stanley Gambarin <gambarin@OpenMarket.com>]
7546 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
7548 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
7549 When used together, these cause mod_dir to emit HEIGHT and WIDTH
7550 attributes in the FancyIndexing IMG tags. [Ken Coar]
7552 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
7554 *) PORT: Added Windows NT support
7555 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
7557 Changes with Apache 1.2.6
7559 *) mod_include when using XBitHack Full would send ETags in addition to
7560 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
7561 [Dean Gaudet] PR#1133
7563 *) SECURITY: When a client connects to a particular port/addr, and
7564 gives a Host: header ensure that the virtual host requested can
7565 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
7567 *) Support virtual hosts with wildcard port and/or multiple ports
7568 properly. [Ed Korthof <ed@organic.com>]
7570 *) Fixed some case-sensitivity issues according to RFC2068.
7573 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
7574 and mod_include.c. [Dean Gaudet]
7576 *) Variable 'cwd' was being used pointlessly before being set.
7579 *) SIGURG doesn't exist on all platforms.
7580 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7582 *) When an error occurs during a POST, or other operation with a
7583 request body, the body has to be read from the net before allowing
7584 a keepalive session to continue. [Roy Fielding] PR#1399
7586 *) When an error occurs in fcntl() locking suggest the user look up
7587 the docs for LockFile. [Dean Gaudet]
7589 *) table_set() and table_unset() did not deal correctly with
7590 multiple occurrences of the same key. [Stephen Scheck
7591 <sscheck@infonex.net>, Ben Laurie] PR#1604
7593 *) send_fd_length() did not calculate total_bytes_sent properly in error
7594 cases. [Ben Reser <breser@regnow.com>] PR#1366
7596 *) r->connection->user was allocated in the wrong pool causing corruption
7597 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
7599 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7600 Also removed the auto-generated link to www.apache.org that was the
7601 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7603 *) Multiple "close" tokens may have been set in the "Connection"
7604 header, not an error, but a waste.
7605 [Ronald.Tschalaer@psi.ch] PR#1683
7607 *) "basic" and "digest" auth tokens should be tested case-insensitive.
7608 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
7610 *) It appears the "257th byte" bug (see
7611 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7612 at the 256th byte as well. Fixed. [Dean Gaudet]
7614 *) mod_rewrite would not handle %3f properly in some situations.
7617 *) Apache could generate improperly chunked HTTP/1.1 responses when
7618 the bputc() or rputc() functions were used by modules (such as
7619 mod_include). [Dean Gaudet]
7621 *) #ifdef wrap a few #defines in httpd.h to make life easier on
7622 some ports. [Ralf Engelschall]
7624 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
7626 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
7628 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
7630 Changes with Apache 1.2.5
7632 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7633 only an issue on systems without a MAXDNAME define or where
7634 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7636 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
7639 *) Fix core dump in the ftp proxy when reading incorrectly formatted
7640 directory listings. [Marc Slemko]
7642 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
7645 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7646 is used to read various types of files such as htaccess and
7647 htpasswd files. [Marc Slemko]
7649 *) SECURITY: Ensure that the buffer returned by ht_time is always
7650 properly null terminated. [Marc Slemko]
7652 *) SECURITY: General mod_include cleanup, including fixing several
7653 possible buffer overflows and a possible infinite loop. This cleanup
7654 was done against 1.3 code and then backported to 1.2, the result
7655 is a large difference (due to indentation cleanup in 1.3 code).
7656 Users interested in seeing a smaller set of relevant differences
7657 should consider comparing against src/modules/standard/mod_include.c
7658 from the 1.3b3 release. Non-indentation changes to mod_include
7659 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
7661 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7662 including fixing a possible buffer overflow. This cleanup also
7663 was done with 1.3 code as a basis, see the the previous note
7664 about mod_include. [Dean Gaudet]
7666 *) SECURITY: If a htaccess file can not be read due to bad
7667 permissions, deny access to the directory with a HTTP_FORBIDDEN.
7668 The previous behavior was to ignore the htaccess file if it could not
7669 be read. This change may make some setups with unreadable
7670 htaccess files stop working. PR#817 [Marc Slemko]
7672 *) SECURITY: no2slash() was O(n^2) in the length of the input.
7673 Make it O(n). This inefficiency could be used to mount a denial
7674 of service attack against the Apache server. Thanks to
7675 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
7678 *) mod_include used uninitialized data for some uses of && and ||.
7679 [Brian Slesinsky <bslesins@wired.com>] PR#1139
7681 *) mod_imap should decline all non-GET methods.
7682 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
7684 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7686 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7687 r->filename. Since those two are meant to be in sync with each other
7688 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7690 *) mod_include did not properly handle all possible redirects from sub-
7691 requests. [Ken Coar]
7693 *) Inetd mode (which is buggy) uses timeouts without having setup the
7694 jmpbuffer. [Dean Gaudet] PR#1064
7696 *) Work around problem under Linux where a child will start looping
7697 reporting a select error over and over.
7698 [Rick Franchuk <rickf@transpect.net>] PR#1107
7700 Changes with Apache 1.2.4
7702 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7703 always making requests with the full-URI instead of just the URI path.
7704 [Marc Slemko, Roy Fielding]
7706 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7707 on this platform. [Marc Slemko]
7709 Changes with Apache 1.2.3
7711 *) The request to a remote proxy was mangled if it was generated as the
7712 result of a ProxyPass directive. URL schemes other than http:// were not
7713 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
7714 PR#812 [Lars Eilebrecht]
7716 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7717 information for case where proxy module is not available. [Marc Slemko]
7719 *) Force proxy to always respond as HTTP/1.0, which it was failing to
7720 do for errors and cached responses. [Roy Fielding]
7722 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
7724 Changes with Apache 1.2.2 [not released]
7726 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7727 happily skip past access checks on subdirectories looked up with relative
7728 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7731 *) Add lockfile name to error message printed out when
7732 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7735 *) Enhanced the chunking and error handling inside the buffer functions.
7736 [Dean Gaudet, Roy Fielding]
7738 *) When merging the main server's <Directory> and <Location> sections into
7739 a vhost, put the main server's first and the vhost's second. Otherwise
7740 the vhost can't override the main server. [Dean Gaudet] PR#717
7742 *) The <Directory> code would merge and re-merge the same section after
7743 a match was found, possibly causing problems with some modules.
7746 *) Fixed an infinite loop in mod_imap for references above the server root.
7747 [Dean Gaudet] PR#748
7749 *) mod_include cleanup showed that handle_else was being used to handle
7750 endif. It didn't cause problems, but it was cleaned up too.
7753 *) Last official synchronization of mod_rewrite with author version (because
7754 mod_rewrite is now directly developed by the author at the Apache Group):
7755 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7756 minus WIN32/NT stuff, but plus copyright removement.
7758 - workaround for detecting infinite rewriting loops
7759 - fixed setting of env vars when "-" is used as subst string
7760 - fixed forced response code on redirects (PR#777)
7761 - fixed cases where r->args is ""
7762 - kludge to disable locking on pipes under braindead SunOS
7763 - fix for rewritelog in cases where remote hostname is unknown
7764 - fixed totally damaged request_rec walk-back loop
7765 o remove static from local data and add static to global ones.
7766 o replaced ugly proxy finding stuff by simple
7767 find_linked_module("mod_proxy") call.
7768 o added missing negation char on rewritelog()
7769 o fixed a few comment typos
7770 [Ralf S. Engelschall]
7772 *) Anonymous_LogEmail was logging on each subrequest.
7773 [Dean Gaudet] PR#421, PR#868
7775 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7776 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7777 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7778 Additionally mod_browser now triggers during translate_name to workaround
7779 a deficiency in the header_parse phase.
7780 [Dean Gaudet] PR#875

7786 *) Properly treat <files> container like other containers in mod_info.
7787 [Marc Slemko] PR#848
7789 *) The proxy didn't treat the "Host:" keyword of the host header as case-
7790 insensitive. The proxy would corrupt the first line of a response from
7791 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
7793 *) mod_include would log some bogus values occasionally.
7794 [Skip Montanaro <skip@calendar.com>, Marc Slemko] PR#797
7796 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
7797 under Solaris 2.x (up through 2.5.1). It has been fixed.
7798 [Dean Gaudet] PR#832
7800 *) API: In HTTP/1.1, whether or not a request message contains a body
7801 is independent of the request method and based solely on the presence
7802 of a Content-Length or Transfer-Encoding. Therefore, our default
7803 handlers need to be prepared to read a body even if they don't know
7804 what to do with it; otherwise, the body would be mistaken for the
7805 next request on a persistent connection. discard_request_body()
7806 has been added to take care of that. [Roy Fielding] PR#378
7808 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
7809 release version number, such that it always increases along the
7810 same lines as our source code branching. [Roy Fielding]
7812 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
7814 Changes with Apache 1.2.1
7816 *) SECURITY: Don't serve file system objects unless they are plain files,
7817 symlinks, or directories. This prevents local users from using pipes
7818 or named sockets to invoke programs for an extremely crude form of

7822 could contain "../" allowing a local user to "publish" any file on
7823 the system. No slashes are allowed now. [Dean Gaudet]
7825 *) SECURITY: It was possible to violate the symlink Options using mod_dir
7826 (headers, readmes, titles), mod_negotiation (type maps), or
7827 mod_cern_meta (meta files). [Dean Gaudet]
7829 *) SECURITY: Apache will refuse to run as "User root" unless
7830 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7832 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7833 if it contained a .htaccess disallowing symlinks. This is contrary
7834 to the rule that symlink permissions are tested with the symlink
7835 options of the parent directory. [Dean Gaudet] PR#353
7837 *) CONFIG: The LockFile directive can be used to place the serializing
7838 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
7839 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
7842 *) Request processing now retains state of whether or not the request
7843 body has been read, so that internal redirects and subrequests will
7844 not try to read it twice (and block). [Roy Fielding]
7846 *) Add a placeholder in modules/Makefile to avoid errors with certain
7847 makes. [Marc Slemko]
7849 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

7855 *) Attempt to work around problems with third party libraries that do not
7856 handle high numbered descriptors (examples include bind, and
7857 solaris libc). On all systems apache attempts to keep all permanent
7858 descriptors above 15 (called the low slack line). Solaris users
7859 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7860 which keeps all non-FILE * descriptors above 255. On all systems
7861 this should make supporting large numbers of vhosts with many open
7862 log files more feasible. If this causes trouble please report it,
7863 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7864 [Dean Gaudet] various PRs
7866 *) Related to the last entry, network sockets are now opened before
7867 log files are opened. The only known case where this can cause
7868 problems is under Solaris with many virtualhosts and many Listen
7869 directives. But using -DHIGH_SLACK_LINE=256 described above will
7870 work around this problem. [Dean Gaudet]
7872 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
7875 *) Improved unix error response logging. [Marc Slemko]
7877 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag

7970 *) Subrequests and internal redirects now inherit the_request from the
7971 original request-line. [Roy Fielding]
7973 *) Test for error conditions before creating output header fields, since
7974 we don't want the error message to include those fields. Likewise,
7975 reset the content_language(s) and content_encoding of the response
7976 before generating or redirecting to an error message, since the new
7977 message will have its own Content-* definitions. [Dean Gaudet]
7979 *) Restored the semantics of headers_out (headers sent only with 200..299
7980 and 304 responses) and err_headers_out (headers sent with all responses).
7981 Avoid the overhead of copying tables if err_headers_out is empty
7982 (the usual case). [Roy Fielding]
7984 *) Fixed a couple places where a check for the default Content-Type was
7985 not properly checking both the value configured by the DefaultType
7986 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
7987 of DEFAULT_TYPE to match the documented default (text/plain).
7988 [Dean Gaudet] PR#506
7990 *) Escape the HTML-sensitive characters in the Request-URI that is
7991 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
7993 *) Properly initialize the flock structures used by the mutex locking
7994 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
7997 *) The method for determining PATH_INFO has been restored to the pre-1.2b
7998 (and NCSA httpd) definition wherein it was the extra path info beyond
7999 the CGI script filename. The environment variable FILEPATH_INFO has
8000 been removed, and instead we supply the original REQUEST_URI to any
8001 script that wants to be Apache-specific and needs the real URI path.
8002 This solves a problem with existing scripts that use extra path info
8003 in the ScriptAlias directive to pass options to the CGI script.
8006 *) The _default_ change in 1.2b10 will change the behaviour on configs
8007 that use multiple Listen statements for listening on multiple ports.
8008 But that change is necessary to make _default_ consistent with other
8009 forms of <VirtualHost>. It requires such configs to be modified
8010 to use <VirtualHost _default_:*>. The documentation has been
8011 updated. [Dean Gaudet] PR#530
8013 *) If an ErrorDocument CGI script is used to respond to an error
8014 generated by another CGI script which has already read the message
8015 body of the request, the server would block trying to read the
8016 message body again. [Rob Hartill]
8018 *) signal() replacement conflicted with a define on QNX (and potentially
8019 other platforms). Fixed. [Ben Laurie] PR#512
8021 Changes with Apache 1.2b10
8023 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
8024 to be configured via -D in Configuration. [Dean Gaudet] PR#449
8026 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
8028 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
8030 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
8031 config, in case the hostent struct returned is trash.
8032 [Chuck Murcko] PR #491
8034 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
8035 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
8037 Changes with Apache 1.2b9 [never announced]
8039 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8040 changes and in anticipation of 1.2 final release. [Roy Fielding]
8042 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8043 the connection (e.g., when user presses Stop). Apache will now stop
8044 trying to send a message body immediately after an error from write.
8045 [Roy Fielding and Nathan Kurz] PR#335
8047 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8048 than mod_alias, and mod_alias has higher priority than mod_proxy;
8049 rearranged other modules to enhance understanding of their purpose
8050 and relative order (and maybe even reduce some overhead).
8051 [Roy Fielding and Sameer Parekh]
8053 *) Fix graceful restart. Eliminate many signal-related race
8054 conditions in both forms of restart, and in SIGTERM. See
8055 htdocs/manual/stopping.html for details on stopping and
8056 restarting the parent. [Dean Gaudet]
8058 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8059 memory allocator to avoid a behaviour that required extra blocks to
8060 be allocated. [Dean Gaudet]
8062 *) Allow suexec to access files relative to current directory but not
8063 above. (Excluding leading / or any .. directory.) [Ken Coar]
8066 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8067 PR#367, 368, 354, 453
8069 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8070 while obtaining the /~user and save the username in a separate data
8071 area so that it won't be overwritten by the call to getgrgid(), and
8072 fix some misuse of the pool string allocation functions. Also fixes
8073 a general problem with parsing URL query info into args for CGI scripts.
8074 [Roy Fielding] PR#339, 367, 354, 453
8076 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
8078 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
8080 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
8081 AuthDBAuthoritative. [Marc Slemko] PR#420
8083 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8085 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8086 object that can't be PUT, or FOOBAR for some method FOOBAR that
8087 apache doesn't know about at all). Log 404s that occur in mod_include.
8088 [Paul Sutton, John Van Essen]
8090 *) If a soft timeout (or lingerout) occurs while trying to flush a
8091 buffer or write inside buff.c or fread'ing from a CGI's output,
8092 then the timeout would be ignored. [Roy Fielding] PR#373
8094 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8095 parsing of headers. If the terminating empty-line CRLF occurs starting
8096 at the 256th or 257th byte of output, then Navigator will think a normal
8097 image is invalid. We are guessing that this is because their initial
8098 read of a new request uses a 256 byte buffer. We check the bytes written
8099 so far and, if we are about to tickle the bug, we instead insert a
8100 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8102 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8103 of an external redirection. [Roy Fielding and Paul Sutton]
8105 *) Configure would create a broken Makefile if the configuration file
8106 contained a commented-out Rule. [Roy Fielding]
8108 *) Promote per_dir_config and subprocess_env from the subrequest to the
8109 main request in mod_negotiation. In particular this fixes a bug
8110 where <Files> sections wouldn't properly apply to negotiated content.
8113 *) Fix a potential deadlock in mod_cgi script_err handling.
8114 [Ralf S. Engelschall]
8116 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8119 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8120 .htaccess files because the RewriteBase was not replaced correctly.
8121 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8122 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8124 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8125 1.x the settings are those of pre-1.2b8. For 2.x we include
8126 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8127 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8128 [Dean Gaudet] PR#336, PR#340
8130 *) Redirect did not preserve ?query_strings when present in the client's
8131 request. [Dean Gaudet]
8133 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
8135 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8137 *) Add UnixWare compile/install instructions. [Chuck Murcko]
8139 *) Add mod_example (illustration of API techniques). [Ken Coar]
8141 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8143 *) Improve handling of directories when filenames have spaces in them.
8146 *) For hosts with multiple IP addresses, try all additional addresses if
8147 necessary to get a connect. Fail only if hostent address list is
8148 exhausted. [Chuck Murcko]
8150 *) More signed/unsigned port fixes. [Dean Gaudet]
8152 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8155 Changes with Apache 1.2b8
8157 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8158 to it. [Marc Slemko]
8160 *) The addition of <Location> and <File> directives made the
8161 sub_req_lookup_simple() function bogus, so we now handle
8162 the special cases directly. [Dean Gaudet]
8164 *) We now try to log where the server is dumping core when a fatal
8165 signal is received. [Ken Coar]
8167 *) Improved lingering_close by adding a special timeout, removing the
8168 spurious log messages, removing the nonblocking settings (they
8169 are not needed with the better timeout), and adding commentary
8170 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8171 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8173 *) Send error messages about setsockopt failures to the server error
8174 log instead of stderr. [Roy Fielding]
8176 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8178 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8179 processing a subrequest, allocate memory from r->main->pool instead
8180 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8181 in the middle of an SSI request. [Dean Gaudet] PR #122
8183 *) Fixed status of response when POST is received for a nonexistent URL
8184 (was sending 405, now 404) and when any method is sent with a
8185 full-URI that doesn't match the server and the server is not acting
8186 as a proxy (was sending 501, now 403). [Roy Fielding]
8188 *) Host port changed to unsigned short. [Ken Coar] PR #276
8190 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8192 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8194 *) Report extra info from errno with many errors that cause httpd to exit.
8195 spawn_child, popenf, and pclosef now have valid errno returns in the
8196 event of an error. Correct problems where errno was stomped on
8197 before being reported. [Dean Gaudet]
8199 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8200 never called, and thus the filesystem would remain full indefinitely.
8201 We now also remove incomplete cache files left if the origin server
8202 didn't send a Content-Length header and either the client has aborted
8203 transfer or bwrite() to client has failed. [Petr Lampa]
8205 *) Fixed the handling of module and script-added header fields.
8206 Improved the interface for sending header fields and reduced
8207 the duplication of code between sending okay responses and errors.
8208 We now always send both headers_out and err_headers_out, and
8209 ensure that the server-reserved fields are not being overridden,
8210 while not overriding those that are not reserved. [Roy Fielding]
8212 *) Moved transparent content negotiation fields to err_headers_out
8213 to reflect above changes. [Petr Lampa]
8215 *) Fixed the determination of whether or not we should make the
8216 connection persistent for all of the cases where some other part
8217 of the server has already indicated that we should not. Also
8218 improved the ordering of the test so that chunked encoding will
8219 be set whenever it is desired instead of only when KeepAlive
8220 is enabled. Added persistent connection capability for most error
8221 responses (those that do not indicate a bad input stream) when
8222 accessed by an HTTP/1.1 client. [Roy Fielding]
8224 *) Added missing timeouts for sending header fields, error responses,
8225 and the last chunk of chunked encoding, each of which could have
8226 resulted in a process being stuck in write forever. Using soft_timeout
8227 requires that the sender check for an aborted connection rather than
8228 continuing after an EINTR. Timeouts that used to be initiated before
8229 send_http_header (and never killed) are now initiated only within or
8230 around the routines that actually do the sending, and not allowed to
8231 propagate above the caller. [Roy Fielding]
8233 *) mod_auth_anon required an @ or a . in the email address, not both.
8236 *) per_dir_defaults weren't set correctly until directory_walk for
8237 name-based vhosts. This fixes an obscure bug with the wrong config
8238 info being used for vhosts that share the same ip as the server.
8241 *) Improved generation of modules/Makefile to be more generic for
8242 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8244 *) Generate makefile dependency for Configuration based on the actual
8245 name given when running the Configure process. [Dean Gaudet]
8247 *) Fixed problem with vhost error log not being set prior to
8248 initializing virtual hosts. [Dean Gaudet]
8250 *) Fixed infinite loop when a trailing slash is included after a type map
8251 file URL (extra path info). [Petr Lampa]
8253 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8255 *) Add documentation for DNS issues (reliability and security), and try
8256 to explain the virtual host matching process. [Dean Gaudet]
8258 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8259 fails while parsing the configuration file. [Dean Gaudet]
8261 *) Improved calls to setsockopt. [Roy Fielding]
8263 *) Negotiation changes: Don't output empty content-type in variant list;
8264 Output charset in variant list; Return sooner from handle_multi() if
8265 no variants found; Add handling of '*' wildcard in Accept-Charset.
8266 [Petr Lampa and Paul Sutton]
8268 *) Fixed overlaying of request/sub-request notes and headers in
8269 mod_negotiation. [Dean Gaudet]
8271 *) If two variants' charset quality are equal and one is the default
8272 charset (iso-8859-1), then prefer the variant that was specifically
8273 listed in Accept-Charset instead of the default. [Petr Lampa]
8275 *) Memory allocation problem in push_array() -- it would corrupt memory
8276 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8278 *) invoke_handler() doesn't handle mime arguments in content-type
8281 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8284 *) Fixed problem with ErrorDocument not working for virtual hosts
8285 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8287 *) Log an error message if we get a request header that is too long,
8288 since it may indicate a buffer overflow attack. [Marc Slemko]
8290 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8291 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8292 [Ken Coar] PR #146, #187
8294 *) Added table entry placeholder for new header_parser callback
8295 in all of the distributed modules. [Ken Coar] PR #191
8297 *) Allow for cgi files without the .EXE extension on them under OS/2.
8298 [Garey Smiley] PR #59
8300 *) Fixed error message when resource is not found and URL contains
8301 path info. [Petr Lampa and Dean Gaudet] PR #40
8303 *) Fixed user and server confusion over what should be a virtual host
8304 and what is the main server, resulting in access to something
8305 other than the name defined in the virtualhost directive (but
8306 with the same IP address) failing. [Dean Gaudet]
8308 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8309 AIX; improves the redirection stuff to enable the users to generally
8310 redirect to http, https, gopher and ftp; added TIME variable for
8311 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8312 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8313 can be used in conjunction with %{TIME} or other variables to create
8314 time-dependent rewriting rules. [Ralf S. Engelschall]
8316 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8317 Module authors may need to adjust their code for proper cleanup to take
8318 place (that is, call note_cleanups_for_fd()). This change fixes problems
8319 with file descriptors being erroneously closed when the proxy module was
8320 in use. [Ben Laurie]
8322 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8323 initgroups() to hose the group information needed for later
8324 comparisons. [Randy Terbush]
8326 *) Remove unnecessary call to va_end() in create_argv() which
8327 caused a SEGV on some systems.
8329 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8332 *) Clear memory allocated for listeners. [Randy Terbush]
8334 *) Improved handling of IP address as a virtualhost address and
8335 introduced "_default_" as a synonym for the default vhost config.

8344 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
8345 - replace protocol response numbers with symbols
8346 - save variant-list into main request notes
8347 - free allocated memory from subrequests
8348 - merge notes, headers_out and err_headers_out
8350 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
8351 "HTTP/#.# ###*" to be more lenient about what we accept.
8354 *) more proxy FTP bug fixes:
8355 - Changed send_dir() to remove user/passwd from displayed URL.
8356 - Changed login error messages to be more descriptive.
8357 - remove setting of SO_DEBUG socket option
8358 - Make ftp_getrc() more lenient about multiline responses,
8359 specifically, 230 responses which don't have continuation 230-
8360 on each line). These seem to be all NT FTP servers, and while
8361 perhaps questionable, they appear to be legal by RFC 959.
8362 - Add missing kill_timeout() after transfer to user completes.
8365 *) Fixed problem where a busy server could hang when restarting
8366 after being sent a SIGHUP due to child processes not exiting.
8369 *) Modify mod_include escaping so a '\' only signifies an escaped
8370 character if the next character is one that needs
8371 escaping. [Ben Laurie]
8373 *) Eliminated possible infinite loop in mod_imap when relative URLs are
8374 used with a 'base' directive that does not have a '/' in it.
8375 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
8377 *) Reduced the default timeout from 1200 seconds to 300, and the
8378 one in the sample configfile from 400 to 300. [Marc Slemko]
8380 *) Stop vbprintf from crashing if given a NULL string pointer;
8381 print (null) instead. [Ken Coar]
8383 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
8384 [Marc Slemko and Roy Fielding]
8386 *) Fixed problem with mod_cgi-generated internal redirects trying to
8387 read the request message-body twice. [Archie Cobbs and Roy Fielding]
8389 *) Reduced timeout on lingering close, removed possibility of a blocked
8390 read causing the child to hang, and stopped logging of errors if
8391 the socket is not connected (reset by client). [Roy Fielding]
8393 *) Rearranged main child loop to remove duplication of code in
8394 select/accept and keep-alive requests, fixed several bugs regarding
8395 checking scoreboard_image for exit indication and failure to
8396 account for all success conditions and trap all error conditions,
8397 prevented multiple flushes before closing the socket; close the entire
8398 socket buffer instead of just one descriptor, prevent logging of
8399 EPROTO and ECONNABORTED on platforms where supported, and generally
8400 improved readability. [Roy Fielding]
8402 *) Extensive performance improvements. Cleaned up inefficient use of
8403 auto initializers, multiple is_matchexp calls on a static string,
8404 and excessive merging of response_code_strings. [Dean Gaudet]
8406 *) Added double-buffering to mod_include to improve performance on
8407 server-side includes. [Marc Slemko]
8409 *) Several fixes for suexec wrapper. [Randy Terbush]
8410 - Make wrapper work for files on NFS filesystem.
8411 - Fix portability problem of MAXPATHLEN.
8412 - Fix array overrun problem in clean_env().
8413 - Fix allocation of PATH environment variable
8415 *) Removed extraneous blank line is description of mod_status chars.
8418 *) Logging of errors from the call_exec routine simply went nowhere,
8419 since the logfile fd has been closed, so now we send them to stderr.
8420 [Harald T. Alvestrand]
8422 *) Fixed core dump when DocumentRoot is a CGI.
8423 [Ben Laurie, reported by geddis@tesserae.com]
8425 *) Fixed potential file descriptor leak in mod_asis; updated it and
8426 http_core to use pfopen/pfclose instead of fopen/fclose.
8427 [Randy Terbush and Roy Fielding]
8429 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
8430 as the DEC Alpha which is 64-bit but uses 32-bit ints.
8431 [Dean Gaudet and Ken Coar]
8433 *) Return a 302 response code to the client when sending a redirect
8434 due to a missing trailing '/' on a directory instead of a 301; now
8435 it is cacheable. [Markus Gyger]
8437 *) Fix condition where, if a bad directive occurs in .htaccess, and
8438 sub_request() goes first to this directory, then log_reason() will
8439 SIGSEGV because it doesn't have initialized r->per_dir_config.
8440 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
8442 *) Fix handling of lang_index in is_variant_better(). This was
8443 causing problems which resulted in the server sending the
8444 wrong language document in some cases. [Petr Lampa]
8446 *) Remove free() from clean_env() in suexec wrapper. This was nuking
8447 the clean environment on some systems.
8449 *) Tweak byteserving code (e.g. serving PDF files) to work around
8450 bugs in Netscape Navigator and Microsoft Internet Explorer.
8451 Emit Content-Length header when sending multipart/byteranges.
8454 *) Port to HI-UX/WE2. [Nick Maclaren]
8456 *) Port to HP MPE operating system for HP 3000 machines

8459 *) Fixed bug which caused a segmentation fault if only one argument
8460 given to RLimit* directives. [Ed Korthof]
8462 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
8464 *) Improved buffered output to the client by delaying the flush decision
8465 until the BUFF code is actually about to read the next request.
8466 This fixes a problem introduced in 1.2b5 with clients that send
8467 an extra CRLF after a POST request. Also improved chunked output
8468 performance by combining writes using writev() and removing as
8469 many bflush() calls as possible. NOTE: Platforms without writev()
8470 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
8471 or Configure, unless we have already done so. [Dean Gaudet]
8473 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
8475 *) Fixed mod_info output corruption bug introduced by buffer overflow
8476 fixes. [Dean Gaudet]
8478 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
8479 for the special case of a 304 response. [Paul Sutton]
8481 *) Improved handling of TRACE method by bypassing normal method handling
8482 and header parsing routines; fixed Allow response to always allow TRACE.
8485 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
8487 *) Cleaned-up some of the generated HTML. [Ken Coar]
8489 Changes with Apache 1.2b6
8491 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
8493 *) Fix typo introduced in fix for potential infinite loop around
8494 accept() in child_main(). This change caused the rev to 1.2b6.
8495 1.2b5 was never a public beta.
8497 Changes with Apache 1.2b5
8499 *) Change KeepAlive semantics (On|Off instead of a number), add
8500 MaxKeepAliveRequests directive. [Alexei Kosut]
8502 *) Various NeXT compilation patches, as well as a change in
8503 regex/regcomp.c since that file also used a NEXT define.
8506 *) Allow * to terminate the end of a directory match in mod_dir.
8507 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
8509 *) Don't call can_exec() if suexec_enabled. Calling this requires
8510 scripts executed by the suexec wrapper to be world executable, which
8511 defeats one of the advantages of running the wrapper. [Randy Terbush]
8513 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
8516 *) Migration from sprintf() to snprintf() to avoid buffer
8517 overflows. [Marc Slemko]
8519 *) Provide portable snprintf() implementation (ap_snprintf)
8520 as well as *cvt family. [Jim Jagielski]
8522 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
8525 *) Remove mod_fastcgi.c from the distribution. This module appears
8526 to be maintained more through the Open Market channels and should
8527 continue to be easily available at http://www.fastcgi.com/
8529 *) Fixed bug in modules/Makefile that wouldn't allow building in more
8530 than one subdirectory (or cleaning, either). [Jeremy Laidman]
8532 *) mod_info assumed that the config files were relative to ServerRoot.
8535 *) CGI scripts called as an error document resulting from failed
8536 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
8538 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
8541 *) Properly check errno to prevent display of a directory index
8542 when server receives a long enough URL to confuse stat().
8545 *) Several security enhancements to suexec wrapper. It is _highly_
8546 recommended that previously installed versions of the wrapper
8547 be replaced with this version. [Randy Terbush, Jason Dour]
8549 - ~user execution now properly restricted to ~user's home
8550 directory and below.
8551 - execution restricted to UID/GID > 100
8552 - restrict passed environment to known variables
8553 - call setgid() before initgroups() (portability fix)
8554 - remove use of setenv() (portability fix)
8556 *) Add HTTP/1.0 response forcing. [Ben Laurie]
8558 *) Add access control via environment variables. [Ben Laurie]
8560 *) Add rflush() function. [Alexei Kosut]
8562 *) remove duplicate pcalloc() call in new_connection().
8564 *) Fix incorrect comparison which could allow number of children =
8565 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
8566 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
8568 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
8569 AIX PS/2, CONVEXOS. [Jim Jagielski]
8571 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
8572 It's more portable. [Martin Kraemer]
8574 *) Replace references to make in Makefile.tmpl with $(MAKE).
8577 *) Add ProxyBlock directive w/IP address caching. Add IP address
8578 caching to NoCache directive as well. ProxyBlock works with all
8579 handlers; NoCache now also works with FTP for anonymous logins.
8580 Still more code cleanup. [Chuck Murcko]
8582 *) Add "header parse" API hook [Ben Laurie]
8584 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
8586 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
8588 *) Correctly allow access and auth directives in <Files> sections in
8589 server config files. [Alexei Kosut]
8591 *) Fix bug with ServerPath that could cause certain files to be not
8592 found by the server. [Alexei Kosut]
8594 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
8595 double-quote from text and so that it properly checks for unsupported
8596 status codes using the new index_of_response interface. [Roy Fielding]
8598 *) Multiple fixes to the lingering_close code in order to avoid being
8599 interrupted by a stray timeout, to avoid lingering on a connection
8600 that has already been aborted or never really existed, to ensure that
8601 we stop lingering as soon as any error condition is received, and to
8602 prevent being stuck indefinitely if the read blocks. Also improves
8603 reporting of error conditions. [Marc Slemko and Roy Fielding]
8605 *) Fixed initialization of parameter structure for sigaction.
8606 [mgyger@itr.ch, Adrian Filipi-Martin]
8608 *) Fixed reinitializing the parameters before each call to accept and
8609 select, and removed potential for infinite loop in accept.
8610 [Roy Fielding, after useful PR from adrian@virginia.edu]
8612 *) Fixed condition where, if a child fails to fork, the scoreboard would
8613 continue to say SERVER_STARTING forever. Eventually, the main process
8614 would refuse to start new children because count_idle_servers() will
8615 count those SERVER_STARTING entries and will always report that there
8616 are enough idle servers. [Phillip Vandry]
8618 *) Fixed bug in bcwrite regarding failure to account for partial writes.
8619 Avoided calling bflush() when the client is pipelining requests.
8620 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
8622 *) Added description of "." mode in server-status [Jim Jagielski]
8624 Changes with Apache 1.2b4
8626 *) Fix possible race condition in accept_mutex_init() that
8627 could leave a small security hole open allowing files to be
8628 overwritten in cases where the server UID has write permissions.
8631 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
8633 *) Fix portablity problem in util_script where ARG_MAX may not be
8634 defined for some systems.
8636 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
8639 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
8640 style magic #! token for better script portability. [Garey Smiley]
8642 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
8643 execution for ~userdir CGI. [Jason Dour]
8645 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
8647 *) Fix month off by one in suexec wrapper logging.
8649 Changes with Apache 1.2b3:
8651 *) Fix error in mod_cgi which could cause resources not to be properly
8652 freed, or worse. [Dean Gaudet]
8654 *) Fix find_string() NULL pointer dereference. [Howard Fear]
8656 *) Add set_flag_slot() at the request of Dirk and others.
8659 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
8661 *) Add changes to improve the error message given for invalid
8662 ServerName parameters. [Dirk vanGulik]
8664 *) Add "Authoritative" directive for Auth modules that don't
8665 currently have it. This gives admin control to assign authoritative
8666 control to an authentication scheme and allow "fall through" for
8667 those authentication modules that aren't "Authoritative" thereby
8668 allowing multiple authentication mechanisms to be chained.
8671 *) Remove requirement for ResourceConfig/AccessConfig if not using
8672 the three config file layout. [Randy Terbush]
8674 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
8676 *) Changes to suexec wrapper to fix the following problems:
8677 1. symlinked homedirs will kill ~userdirs.
8678 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8679 3. CGI command lines paramters problems
8680 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8681 [Randy Terbush, Jason Dour]
8683 *) Change create_argv() to accept variable arguments. This fixes
8684 a problem where arguments were not getting passed to the CGI via
8685 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8687 *) Collapse multiple slashes in path URLs to properly apply
8688 handlers defined by <Location>. [Alexei Kosut]
8690 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8692 *) Improve the accuracy of request duration timings by setting
8693 r->request_time in read_request_line() instead of read_request().
8696 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8697 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8699 *) Add the ability to pass different Makefile.tmpl files to Configure
8700 using the -make flag. [Rob Hartill]
8702 *) Fix coredump triggered when sending a SIGHUP to the server caused
8703 by an assertion failure, in turn caused by an uninitialised field in a
8707 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8708 PATH_INFO from previous versions of Apache (in certain situations,
8709 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
8710 [later removed in 1.2b11]
8712 *) Add rwrite() function to API to allow for sending strings of
8713 arbitrary length. [Doug MacEachern]
8715 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
8717 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
8718 NeXT. [Jim Jagielski]
8720 *) Removed recent modification to promote the status code on internal
8721 redirects, since the correct fix was to change the default log format
8722 in mod_log_config so that it outputs the original status. [Rob Hartill]
8724 Changes with Apache 1.2b2:
8726 *) Update set_signals() to use sigaction() for setting handlers.
8727 This appears to fix a re-entrant problem in the seg_fault()
8728 bus_error() handlers. [Randy Terbush]
8730 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8732 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8734 *) proxy_http.c bugfixes: [Chuck Murcko]
8735 1) fixes possible NULL pointer reference w/NoCache
8736 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8737 host would cache nothing if it was in the local domain,
8738 and the local domain was in the NoCache list)
8739 3) Adds Host: header when not available
8740 4) Some code cleanup and clarification
8742 *) mod_include.c bugfixes:
8743 1) Fixed an ommission that caused include variables to not
8744 be parsed in config errmsg directives [Howard Fear]
8745 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8746 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8747 4) Allow backslash-escaping to all quoted text
8748 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8749 5) Pass variable to command line if not set in XSSI's env
8752 *) Fix infinite loop when processing Content-language lines in
8753 type-map files. [Alexei Kosut]
8755 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8757 *) Fixed problem in set_[user|group] that prevented CGI execution
8758 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8760 *) Added PORTING information file. [Jim Jagielski]
8762 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8764 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8766 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8767 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8769 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8770 which caused problems of systems where socket s_addr is >32bits.
8772 *) Added comment to explain (r->chunked = 1) side-effect in
8773 http_protocol.c [Roy Fielding]
8775 *) Replaced use of index() in mod_expires.c with more appropriate
8776 and portable isdigit() test. [Ben Laurie]
8778 *) Updated Configure for ...
8779 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8780 *-dg-dgux* (bad pattern match)
8781 QNX (DEF_WANTHSREGEX=yes)
8782 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8785 and added some user diagnostic info. [Ben Laurie]
8787 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8788 for better portability. [Jim Jagielski]
8790 *) Updated helpers/GuessOS for ...
8791 SCO 5 (recognize minor releases)
8792 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8793 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8794 IRIX64 (-sgi-irix64)
8795 ULTRIX (-unknown-ultrix)
8796 SINIX (-whatever-sysv4)
8797 NCR Unix (-ncr-sysv4)
8798 and fixed something in helpers/PrintPath [Ben Laurie]
8800 Changes with Apache 1.2b1
8802 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8804 Changes with Apache 1.1.1
8806 *) Fixed bug where Cookie module would make two entries in the
8807 logfile for each access [Mark Cox]
8809 *) Fixed bug where Redirect in .htaccess files would cause memory
8810 leak. [Nathan Neulinger]
8812 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8814 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8816 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8818 Changes with Apache 1.1.0
8820 *) Bring NeXT support up to date. [Takaaki Matsumoto]
8822 *) Bring QNX support up to date. [Ben Laurie]
8824 *) Make virtual hosts default to main server keepalive parameters.
8825 [Alexei Kosut, Ben Laurie]
8827 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8829 *) Fix missing address family for connect, also remove unreachable statement
8830 in mod_proxy. [Ben Laurie]
8832 *) mod_env now turned on by default in Configuration.tmpl.
8834 *) Bugs which were fixed:
8835 a) yet more mod_proxy bugs [Ben Laurie]
8836 b) CGI works again with inetd [Alexei Kosut]
8837 c) Leading colons were stripped from passwords [osm@interguide.com]
8838 d) Another fix to multi-method Limit problem [jk@tools.de]
8840 Changes with Apache 1.1b4
8842 *) r->bytes_sent variable restored. [Robert Thau]
8844 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8846 *) More possibly unsecure programs removed from the support directory.
8848 *) More mod_auth_msql authentication improvements.
8850 *) VirtualHosts based on Host: headers no longer conflict with the
8853 *) OS/2 compatibility enhancements. [Gary Smiley]
8855 *) POST now allowed to directory index CGI scripts.
8857 *) Actions now work with files of the default type.
8859 *) Bugs which were fixed:
8860 a) more mod_proxy bugs
8861 b) early termination of inetd requests
8862 c) compile warnings on several systems
8863 d) problems when scripts stop reading output early
8865 Changes with Apache 1.1b3
8867 *) Much of cgi-bin and all of cgi-src has been removed, due to
8868 various security holes found and that we could no longer support
8871 *) The "Set-Cookie" header is now special-cased to not merge multiple
8872 instances, since certain popular browsers can not handle multiple
8873 Set-Cookie instructions in a single header. [Paul Sutton]
8875 *) rprintf() added to buffer code, occurrences of sprintf removed.
8878 *) CONNECT method for proxy module, which means tunneling SSL should work.
8879 (No crypto needed) Also a NoCache config directive.
8881 *) Several API additions: pstrndup(), table_unset() and get_token()
8882 functions now available to modules.
8884 *) mod_imap fixups, in particular Location: headers are now complete
8887 *) New "info" module which reports on installed module set through a
8888 special URL, a la mod_status.
8890 *) "ServerPath" directive added - allows for graceful transition
8891 for Host:-header-based virtual hosts.
8893 *) Anonymous authentication module improvements.
8895 *) MSQL authentication module improvements.
8897 *) Status module design improved - output now table-based. [Ben Laurie]
8899 *) htdigest utility included for use with digest authentication
8902 *) mod_negotiation: Accept values with wildcards to be treated with
8903 less priority than those without wildcards at the same quality
8904 value. [Alexei Kosut]
8906 *) Bugs which were fixed:
8907 a) numerous mod_proxy bugs
8908 b) CGI early-termination bug [Ben Laurie]
8909 c) Keepalives not working with virtual hosts
8910 d) RefererIgnore problems
8911 e) closing fd's twice in mod_include (causing core dumps on
8912 Linux and elsewhere).
8914 Changes with Apache 1.1b2
8917 a) core dumps in mod_digest
8918 b) truncated hostnames/ip address in the logs
8919 c) relative URL's in mod_imap map files
8921 Changes with Apache 1.1b1
8923 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
8925 Changes with Apache 1.0.3
8927 *) Internal redirects which occur in mod_dir.c now preserve the
8928 query portion of a request (the bit after the question mark).
8931 *) Escape active characters '<', '>' and '&' in html output in
8932 directory listings, error messages and redirection links.
8935 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
8937 *) Fix for POSIX compliance in waiting for processes in alloc.c.
8940 *) setsockopt no longer takes a const declared argument [Martijn Koster]
8942 *) Reset timeout timer after each successful fwrite() to the network.
8943 This patch adds a reset_timeout() procedure that is called by
8944 send_fd() to reset the timeout ever time data is written to the net.
8947 *) timeout() signal handler now checks for SIGPIPE and reports
8948 lost connections in a more user friendly way. [Rob Hartill]
8950 *) Location of the "scoreboard" file which used to live in /tmp is
8951 now configurable (for OSes that can't use mmap) via ScoreBoardFile
8952 which works similar to PidFile (in httpd.conf) [Rob Hartill]
8954 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
8956 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
8957 which caused a SEGV with cookies enabled
8959 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
8962 *) Log the UNIX textual error returned by some system calls, in
8963 particular errors from accept() [David Robinson]
8965 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
8967 Changes with Apache 1.0.2
8969 *) patch to get Apache compiled on UnixWare 2.x, recommended as
8970 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
8972 *) Fix get_basic_auth_pw() to set the auth_type of the request.
8975 *) past changes to http_config.c to only use the
8976 setrlimit function on systems defining RLIMIT_NOFILE
8977 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
8978 for SUNOS and prototypes the needed functions.
8980 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
8983 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
8985 *) Merge multiple headers from CGI scripts instead of taking last
8986 one. [David Robinson]
8988 *) Add support for SCO 5. [Ben Laurie]
8990 Changes with Apache 1.0.1
8992 *) Silence mod_log_referer and mod_log_agent if not configured
8995 *) Recursive includes can occur if the client supplies PATH_INFO data
8996 and the server provider uses relative links; as file.html
8997 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
8999 *) The replacement for initgroups() did not call {set,end}grent(). This
9000 had two implications: if anything else used getgrent(), then
9001 initgroups() would fail, and it was consuming a file descriptor.
9004 *) On heavily loaded servers it was possible for the scoreboard to get
9005 out of sync with reality, as a result of a race condition.
9006 The observed symptoms are far more Apaches running than should
9007 be, and heavy system loads, generally followed by catastrophic
9008 system failure. [Ben Laurie]
9010 *) Fix typo in license. [David Robinson]
9012 Changes with Apache 1.0.0 23 Nov 1995
9014 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9016 Changes with Apache 0.8.16 05 Nov 1995
9018 *) New man page for 'httpd' added to support directory [David Robinson]
9020 *) .htgroup files can have more than one line giving members for a
9021 given group (each must have the group name in front), for NCSA
9022 back-compatibility [Robert Thau]
9024 *) Mutual exclusion around accept() is on by default for SVR4 systems
9025 generally, since they generally can't handle multiple processes in
9026 accept() on the same socket. This should cure flaky behavior on
9027 a lot of those systems. [David Robinson]
9029 *) AddType, AddEncoding, and AddLanguage directives take multiple
9030 extensions on a single command line [David Robinson]
9032 *) UserDir can be disabled for a given virtual host by saying
9033 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9034 that this didn't work. [David Robinson]
9036 *) Compiles on QNX [Ben Laurie]
9038 *) Corrected parsing of ctime time format [David Robinson]
9040 *) httpd does a perror() before exiting if it can't log its pid
9041 to the PidFile, to make diagnosing the error a bit easier.
9044 *) <!--#include file="..."--> can no longer include files in the
9045 parent directory, for NCSA back-compatibility. [David Robinson]
9047 *) '~' is *not* escaped in URIs generated for directory listings
9050 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9052 *) Fixed bug involving handling URIs with escaped %-characters
9053 in redirects [David Robinson]
9055 Changes with Apache 0.8.15 14 Oct 1995
9057 *) Switched to new, simpler license
9059 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9061 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9063 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9065 *) Correctly handles internal redirects to files with names containing '%'
9068 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9070 *) Use geteuid() rather than getuid() to see if we have root privilege,
9071 so that server correctly resets privilege if run setuid root. [Andrew
9074 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9077 *) Fix relative URLs in imagemap files [Randy Terbush]
9079 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9082 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9083 entries all name the same one. [David Robinson]
9085 *) Fix directory listings with filenames containing unusual characters
9088 *) Better URI-escaping for generated URIs in directories with filenames
9089 containing unusual characters [Ben Laurie]
9091 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9093 *) Unblock alarms on error return from spawn_child() [David Robinson]
9095 *) Sample Config files have extra note for SCO users [Ben Laurie]
9097 *) Configuration has note for HP-UX users [Rob Hartill]
9099 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9101 *) Nuked bogus #define in httpd.h [David Robinson]
9103 *) Better test for whether a system has setrlimit() [David Robinson]
9105 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9107 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9110 Changes with Apache 0.8.14 19 Sep 1995
9112 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9114 *) AddDescription works (better) [Ben Laurie]
9116 *) Leaves an intelligible error diagnostic when it can't set group
9117 privileges on standalone startup [Andrew Wilson]
9119 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9120 that machine, which claims to be BSD but does not support RLIMIT.
9123 *) gcc -Wall no longer complains about an unused variable when util.c
9124 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9126 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9128 Changes with Apache 0.8.13 07 Sep 1995
9130 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9132 *) Have built-in imagemap code recognize & honor Point directive [James
9135 *) Generate cleaner directory listings in directories with a mix of
9136 long and short filenames [Rob Hartill]
9138 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9140 *) Properly default ServerName for virtual servers [Robert Thau]
9142 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9143 Paul Richards and a cast of thousands...]
9145 *) On self-identified BSD systems (we don't try to guess any more),
9146 allocate a few extra file descriptors per virtual host with setrlimit,
9147 if we can, to avoid running out. [Randy Terbush]
9149 *) Write 22-character lock file name into buffer with enough space
9150 on startup [Konstantin Olchanski]
9152 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9155 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9157 *) Suppress -Wall warning by initializing variable in negotiation code
9158 [Tobias Weingartner]
9160 Changes with Apache 0.8.12 31 Aug 1995
9162 *) Doesn't pause three seconds after including a CGI script which is
9163 too slow to die off (this is done by not even trying to kill off
9164 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9165 after the entire document has been processed). [Robert Thau]
9167 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9169 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9171 *) Allows .htaccess files to override <Directory> sections naming the
9172 same directory [David Robinson]
9174 *) Removed an efficiency hack in sub_req_lookup_uri which was
9175 causing certain extremely marginal cases (e.g., ScriptAlias of a
9176 *particular* index.html file) to fail. [David Robinson]
9178 *) Doesn't log an error when the requested URI requires
9179 authentication, but no auth header line was supplied by the
9180 client; this is a normal condition (the client doesn't no auth is
9181 needed here yet). [Robert Thau]
9183 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9185 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9187 *) RFC931 code no longer passes out name of prior clients on current
9188 requests if the current request came from a server that doesn't
9189 do RFC931. [David Robinson]
9191 *) Configuration script accepts "Module" lines with trailing whitespace.
9194 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9196 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9198 Changes with Apache 0.8.11 24 Aug 1995
9200 *) Wildcard <Directory> specifications work. [Robert Thau]
9202 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9204 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9205 the file being requested itself, in addition to the directories leading
9206 up to it. [Robert Thau]
9208 *) Logs access failures due to symlink checks or invalid client address
9209 in the error log [Roy Fielding, Robert Thau]
9211 *) Symlink checks deal correctly with systems where lstat of
9212 "/path/to/some/link/" follows the link. [Thau, Fielding]
9214 *) Doesn't reset DirectoryIndex to 'index.html' when
9215 other directory options are set in a .htaccess file. [Robert Thau]
9217 *) Clarified init code and nuked bogus warning in mod_access.c
9220 *) Corrected several directives in sample srm.conf
9221 --- includes corrections to directory indexing icon-related directives
9222 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9223 icons for encodings right, and turning on AddEncoding by default).
9226 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9229 *) INSTALL & README mention "contributed modules" directory [Brian
9232 *) Fixed English in the license language... "for for" --> "for".
9235 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9236 mod_alias.c, merging it almost completely with handling of Alias, and
9237 adding a 'notes' field to the request_rec which allows the CGI module
9238 to discover whether the Alias module has put this request through
9239 ScriptAlias (which it needs to know for back-compatibility, as the old
9240 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9243 Changes with Apache 0.8.10 18 Aug 1995
9245 *) AllowOverride applies to the named directory, and not just
9246 subdirectories. [David Robinson]
9248 *) Do locking for accept() exclusion (on systems that need it)
9249 using a special file created for the purpose in /usr/tmp, and
9250 not the error log; using the error log causes real problems
9251 if it's NFS-mounted; this is known to be the cause of a whole
9252 lot of "server hang" problems with Solaris. [David Robinson;
9253 thanks to Merten Schumann for help diagnosing the problem].
9255 Changes with Apache 0.8.9 12 Aug 1995
9257 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9259 *) Nested includes see environment variables of the including document,
9260 for NCSA bug-compatibility (some sites have standard footer includes
9261 which try to print out the last-modified date). [Eric Hagberg/Robert
9264 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9265 URI as a CGI script, even if it would have been treated as something
9266 else if requested directly, for NCSA back-compatibility. (Note that
9267 this means that people who know the name of the script can see the
9268 code just by asking for it). [Robert Thau]
9270 *) New version of dbmmanage script included in support directory as
9273 *) Check if scoreboard file couldn't be opened, and say so, rather
9274 then going insane [David Robinson]
9276 *) POST to CGI works on A/UX [Jim Jagielski]
9278 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9280 *) NCSA server push works properly --- the Arena bug compatibility
9281 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9282 if you still want the workaround). [Rob Hartill]
9284 *) If client didn't submit any Accept-encodings, ignore encodings in
9285 content negotiation. (NB this will all have to be reworked anyway
9286 for the new HTTP draft). [Florent Guillaume]
9288 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9290 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9292 *) Give Redirect priority over Alias, for NCSA bug compatibility
9295 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9296 paralleling earlier bug fix for CGI [David Robinson]
9298 *) If DBM auth is improperly configured, report a server error and don't
9301 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9302 it seems to work well enough without it (even in a 10 hits/sec
9303 workout), and the overhead for the locking under A/UX is
9304 alarmingly high (though it is very low on other systems).
9305 [Eric Hagberg, Jim Jagielski]
9307 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9309 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9310 Behlendorf/Eric Hagberg]
9312 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9314 *) Compiles clean on NEXT [Rob Hartill]
9316 *) Compiles clean on SGI [Robert Thau]
9318 Changes with Apache 0.8.8 08 Aug 1995
9320 *) SunOS library prototypes now never included unless explicitly
9321 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9322 people using GNU libc on SunOS are screwed by prototypes for the
9325 (Those who wish to compile clean with gcc -Wall on a standard
9326 SunOS setup need the prototypes, and may obtain them using
9327 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9328 with nonstandard libraries are presumably competent to make their
9331 *) Strips trailing '/' characters off both args to the Alias command,
9332 to make 'Alias /foo/ /bar/' work.
9334 Changes with Apache 0.8.7 03 Aug 1995
9336 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9337 [reported by David Robinson]
9339 *) Compiles clean on OSF/1 [David Robinson]
9341 *) Added some of the more recent significant changes (AddLanguage stuff,
9342 experimental LogFormat support) to CHANGES file in distribution root
9345 Changes with Apache 0.8.6 02 Aug 1995
9347 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9348 (If you actually wanted a conditional GET which bypassed the cache, you
9349 couldn't get it). [Reported by Roy Fielding]
9351 *) Properly terminate headers on '304 Not Modified' replies to conditional
9352 GETs --- no browser we can find cares much, but the CERN proxy chokes.
9353 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
9355 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
9357 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
9358 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
9359 and older versions don't set the __SUNPRO_C preprocessor variable). On
9360 all other systems, these are never used anyway. [Reported by Mark Cox].
9362 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9364 Changes with Apache 0.8.5 01 Aug 1995
9366 *) Added last-minute configurable log experiment, as optional module
9368 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9369 properly. (One-line fix to http_protocol.c).
9371 *) Work around bogus behavior when reloading from Netscape.
9372 It's Netscape's bug --- for some reason they expect a request with
9373 If-modified-since: to not function as a conditional GET if it also
9374 comes with Pragma: no-cache, which is way out of line with the HTTP
9375 spec (according to Roy Fielding, the redactor).
9377 *) Added parameter to set maximum number of server processes.
9379 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9382 *) IdentityCheck bugfix [Chuck Murcko].
9384 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
9386 *) More sample config file corrections; add extension to AddType for
9387 *.asis, move AddType generic description to its proper place, and
9388 fix miscellaneous typos. [ Alexei Kosut ]
9390 *) Deleted the *other* reference to the regents from the Berkeley
9391 legal disclaimer (everyplace).
9393 *) Nuked Shambhala name from src/README; had already cleaned it out
9396 Changes with Apache 0.8.4
9398 *) Changes to server-pool management parms --- renamed current
9399 StartServers to MinSpareServers, created separate StartServers
9400 parameter which means what it says, and renamed MaxServers to
9401 MaxSpareServers (though the old name still works, for NCSA 1.4
9402 back-compatibility). The old names were generally regarded as
9403 too confusing. Also altered "docs" in sample config files.
9405 *) More improvements to default config files ---
9406 sample directives (commented out) for XBitHack, BindAddress,
9407 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
9408 defaults, AddTypes for send-as-is and imagemap magic types, and
9409 improvements to samples for DirectoryIndex [Alexei Kosut]
9411 *) Yet more improvements to default config files --- changes to
9412 Alexei's sample AddLanguage directives, and sample LanguagePriority
9413 [ Florent Guillaume ]
9415 *) Set config file locations properly if not set in httpd.conf
9418 *) Don't escape URIs in internal redirects multiple times; don't
9419 do that when translating PATH_INFO to PATH_TRANSLATED either.
9422 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
9424 Changes with Apache 0.8.3
9426 *) Edited distribution README to *briefly* summarize installation
9427 procedures, and give a pointer to the INSTALL file in the src/
9430 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
9431 recent NCSA distributions.
9433 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
9434 exist for the same directory, use both and don't segfault. [Reported
9437 *) Proper makefile dependencies [David Robinson]
9439 *) Note (re)starts in error log --- reported by Rob Hartill.
9441 *) Only call no2slash() after get_path_info() has been done, to
9442 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
9443 reported by Andrew Wilson, though this one is probably a real bug]
9445 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
9446 dump core when Referer is not supplied. [Randy Terbush]
9448 *) Lightly edited sample config files to refer people to our documentation
9449 instead of NCSA's, and to list Rob McCool as *original* author (also
9450 deleted his old, and no doubt non-functional email address). Would be
9451 nice to have examples of new features...
9453 Changes with Apache 0.8.2 19 Jul 1995
9455 *) Added AddLanuage code [Florent Guillaume]
9457 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
9459 *) All sorts of problems when MultiViews finds a directory. It would
9460 be nice if mod_dir.c was robust enough to handle that, but for now,
9461 just punt. [reported by Brian Behlendorf]
9463 *) Wait for all children on restart, to make sure that the old socket
9464 is gone and we can reopen it. [reported by Randy Terbush]
9466 *) Imagemap module is enabled in default Configuration
9468 *) RefererLog and UserAgentLog modules properly default the logfile
9471 *) Mark Cox's mod_cookies added to the distribution as an optional
9472 module (commented out in the default Configuration, and noted as
9473 an experiment, along with mod_dld). [Mark Cox]
9475 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
9477 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
9479 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
9481 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
9484 Changes with Apache 0.8.1
9486 *) New imagemap module [Randy Terbush]
9488 *) Replacement referer log module with NCSA-compatible RefererIgnore
9489 [Matthew Gray again]
9491 *) Don't mung directory listings with very long filenames.
9494 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
9496 *) New config script. See INSTALL for info. [Robert Thau]
9498 *) Scoreboard mechanism for regulating the number of extant server
9499 processes. MaxServers and StartServers defaults are the same as
9500 for NCSA, but the meanings are slightly different. (Actually,
9501 I should probably lower the MaxServers default to 10).
9503 Before asking for a new connection, each server process checks
9504 the number of other servers which are also waiting for a
9505 connection. If there are more than MaxServers, it quietly dies
9506 off. Conversely, every second, the root, or caretaker, process
9507 looks to see how many servers are waiting for a new connection;
9508 if there are fewer than StartServers, it starts a new one. This
9509 does not depend on the number of server processes already extant.
9510 The accounting is arranged through a "scoreboard" file, named
9511 /tmp/htstatus.*, on which each process has an independent file
9512 descriptor (they need to seek without interference).
9514 The end effect is that MaxServers is the maximum number of
9515 servers on an *inactive* server machine, but more will be forked
9516 off to handle unusually heavy loads (or unusually slow clients);
9517 these will die off when they are no longer needed --- without
9518 reverting to the overhead of full forking operation. There is a
9519 hard maximum of 150 server processes compiled in, largely to
9520 avoid forking out of control and dragging the machine down.
9521 (This is arguably too high).
9523 In my server endurance tests, this mechanism did not appear to
9524 impose any significant overhead, even after I forced it to put the
9525 scoreboard file on a normal filesystem (which might have more
9526 overhead than tmpfs). [Robert Thau]
9528 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
9531 *) Read .htaccess files even in directory with <Directory> section.
9532 (Former incompatibility noted on mailing list, now fixed). [Robert
9535 *) "HEAD /" gives the client a "Bad Request" error message, rather
9536 than trying to send no body *and* no headers. [Cliff Skolnick].
9538 *) Don't produce double error reports for some very obscure cases
9539 mainly involving auth configuration (the "all modules decline to
9540 handle" case which is a sure sign of a server bug in most cases,
9541 but also happens when authentication is badly misconfigured).
9544 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
9545 it's *for*, and this sort of thing really shouldn't be cluttering
9546 up the Makefile). [Robert Thau]
9548 *) Incidental code cleanups in http_main.c --- stop dragging
9549 sa_client around; just declare it where used. [Robert Thau]
9551 *) Another acc-related fix. (It doesn't like const char
9552 in some places...). [Mark Cox]
9554 Changes with Shambhala 0.6.1 13 Jul 1995
9556 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
9557 Also, fixed auth typo in http_protocol.c unmasked by this fix.
9559 *) Compiles clean with acc on SunOS [Paul Sutton]
9561 *) Reordered modules in modules.c so that Redirect takes priority
9562 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
9563 believe it or not, he has an actual site with a ScriptAlias and
9564 a Redirect declared for the *exact same directory*. Even *my*
9565 compatibility fetish wouldn't motivate me to fix this if the fix
9566 required any effort, but it doesn't, so what the hey.
9568 *) Fixed to properly default several server_rec fields for virtual
9569 servers from the corresponding fields in the main server_rec.
9570 [Cliff Skolnick --- 'port' was a particular irritant].
9572 *) No longer kills off nph- child processes before they are
9573 finished sending output. [Matthew Gray]
9575 Changes with Shambhala 0.6.0 10 Jul 1995
9577 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
9578 the connection to the client in an "aborted" state, but otherwise
9579 allow whatever handlers are running to clean up. hard_timeout()s
9580 abort the request in progress completely; anything not tied to some
9581 resource pool cleanup will leak. They're still around because I
9582 haven't yet come up with a more elegant way of handling
9583 timeouts when talking to something that isn't the client. The
9584 default_handler and the dir_handler now use soft timeouts, largely
9585 so I can test the feature. [Robert Thau]
9587 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
9588 the case of log handlers dying prematurely is probably handled VERY
9589 gracelessly at this point, and if the logger stops reading input,
9590 the server will hang. (It is known to correctly restart the
9591 logging process on server restart; this is (should be!) going through
9592 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
9593 script). [Robert Thau]
9595 *) asis files supported (new module). [Robert Thau]
9597 *) IdentityCheck code is compiled in, but has not been tested. (I
9598 don't know anyone who runs identd). [Robert Thau]
9600 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
9601 came in with the request, for NCSA bug-compatibility. [Robert Thau]
9603 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
9605 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
9606 as timeouts are not in scope. [Robert Thau]
9608 *) quoted-string args in config files now handled correctly (doesn't drop
9609 the last character). [Robert Thau; reported by Randy Terbush]
9611 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
9612 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
9614 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
9615 default default type); the former default default behavior when all
9616 type-checkers defaulted had been a core dump. [Paul Sutton]
9618 *) Copy filenames out of the struct dirent when indexing
9619 directories. (On Linux, readdir() returns a pointer to the same
9620 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
9622 Changes with Shambhala 0.5.3 [not released]
9624 *) Default response handler notes "file not found" in the error log,
9625 if the file was not found. [Cliff Skolnick].
9627 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
9628 code no longer sets up bogus PATH_INFO which fakes out the directory
9629 handler). [Cliff Skolnick]
9631 Changes with Shambhala 0.5.2 06 Jul 1995
9633 *) Changes to http_main.c --- root server no longer plays silly
9634 games with SIGCHLD, and so now detects and replaces dying
9635 children. Child processes just die on SIGTERM, without taking
9636 the whole process group with them. Potential problem --- if any
9637 child process refuses to die, we hang in restart.
9638 MaxRequestsPerChild may still not work, but it certainly works
9639 better than it did before this! [Robert Thau]
9641 *) mod_dir.c bug fixes: ReadmeName and HeaderName
9642 work (or work better, at least); over-long description lines
9643 properly terminated. [Mark Cox]
9645 *) http_request.c now calls unescape_url() more places where it
9646 should [Paul Sutton].
9648 *) More directory handling bugs (reported by Cox)
9649 Parent Directory link is now set correctly. [Robert Thau]
9651 Changes with Shambhala 0.5.1 04 Jul 1995
9653 *) Generalized cleanup interface in alloc.c --- any function can be
9654 registered with alloc.c as a cleanup for a resource pool;
9655 tracking of files and file descriptors has been reimplemented in
9656 terms of this interface, so I can give it some sort of a test.
9659 *) More changes in alloc.c --- new cleanup_for_exec() function,
9660 which tracks down and closes all file descriptors which have been
9661 registered with the alloc.c machinery before the server exec()s a
9662 child process for CGI or <!--#exec-->. CGI children now get
9663 started with exactly three file descriptors open. Hopefully,
9664 this cures the problem Rob H. was having with overly persistent
9665 CGI connections. [Robert Thau]
9667 *) Mutual exclusion around the accept() in child_main() --- this is
9668 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
9669 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
9670 This uses fcntl(F_SETLK,...) on the error log descriptor because
9671 flock() on that descriptor won't work on systems which have BSD
9672 flock() semantics, including (I think) Linux 1.3 and Solaris.
9674 This does work on SunOS (when the server is idle, only one
9675 process in the pool is waiting on accept()); it *ought* to work
9676 on the other systems. [Robert Thau]
9678 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9680 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9682 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9684 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9685 be unnecessary if I go to the revised timeout-handling scheme).
9688 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9689 string) even if none came in with the request. [Robert Thau]
9691 *) CHANGES file added to distribution ;-).
9693 Changes with Shambhala 0.4.5
9695 *) mod_dld --- early dynamic loading support [rst]
9696 *) Add wildcard content handlers for XBITHACK; default_hander now
9697 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9698 *) XBITHACK supported as a wildcard content-handler, and
9699 configurable at run-time (not just at compile time, as in the
9700 "patchy server" releases) [rst]
9702 Changes with Shambhala 0.4.4 30 Jun 1995
9704 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9705 *) Handle Addtype x/y .z [rst, reported by Cox]
9707 Changes with Shambhala 0.4.3
9709 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
9710 synonymous [rst, terbush]
9712 Changes with Shambhala 0.4.1 28 Jun 1995
9714 *) First-cut virtual host implementation; some refit in the config
9715 reading code, and log management, was necessary to support this [rst]
9716 *) Sub-pool machinery, originally added to avoid excessive storage
9717 allocation on listings of large directories (which turned out to
9718 be the problem that the 0.3 storage accounting was added to
9719 find). Subrequests and mod_dir changed to use subpools. [rst]
9720 *) More memory debugging --- free list consistency checks. [rst]
9721 *) Added err_headers to request_rec, with support elsewhere [rst]
9722 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9724 Changes with Shambhala 0.3 19 Jun 1995
9726 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9727 *) Don't compile in mod_ai_backcompat by default
9728 *) Switch name of server from Apache to Shambhala in Makefile
9729 *) Add some accounting routines to track memory usage in the pools,
9732 Changes with Shambhala 0.2
9734 *) Set DOCUMENT_ROOT CGI variable
9735 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9736 *) Add critical section protection to handling of cleanup structures
9738 *) Significant code reorg within the server core to group related
9739 functions together [rst]
9740 *) Correctly handle clients that hang up before sending any request
9742 *) Replace dying child processes. [rst]
9744 Changes with Shambhala 0.1 12 Jun 1995
9746 Major rewrite of the pre-existing "patchy server" codebase, by
9747 Robert Thau (rst). Significant portions of the server code, such
9748 as configuration-file handling and HTTP authentication support,
9749 were ripped out and rewritten from scratch. Code that was not
9750 completely rewritten was significantly altered.
9752 Major changes with this release include:
9754 *) Introduction of the module API; in request handling, the central
9755 machinery just dispatches to various modules, which actually do
9756 most of the work. Configuration handling is similar --- modules
9757 declare their own commands, and the central machinery just
9760 API features from shambhala/0.1 were substantially unchanged in
9761 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9762 release, such as wildcard handlers and subpools, were added in
9763 subsequent Shambhala releases, and were also generally rst's
9766 *) This release included the following modules:
9768 mod_access (access control --- allow and deny directives),
9769 mod_alias (Alias and Redirect commands),
9770 mod_auth (straight HTTP authentication, based on flat-files)
9771 mod_auth_dbm (same, with dbm files)
9772 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9773 mod_common_log (CLF access logs; later renamed mod_log_common)
9774 mod_dir (directory indexing)
9775 mod_include (server-side includes)
9776 mod_mime (AddType directives)
9777 mod_negotiation (content negotiation)
9778 mod_userdir (support for users' public_html directories)
9780 It also included a mod_ai_backcompat, which was a private hack
9781 for back-compatibility with rst's own AI-lab servers.
9783 All of these modules were substantially complete, and functional
9784 or nearly so (a few, which implemented features not in use at
9785 Thau's site, required patches of a few lines).
9787 *) sub-request machinery, to allow modules to determine how other
9788 modules would assign MIME types to a given file, or optionally
9789 serve its content (this is heavily used by mod_dir, mod_include
9790 and mod_negotiation).
9792 *) Resource pool system for keeping track of memory allocated and
9793 files opened in service of a particular request. Much of the
9794 code in the modules (when they weren't rewrites) was adjusted to
9795 replace a pervasive convention of using fixed-size buffers on
9796 the stack with an equally pervasive convention of using memory
9797 allocated with palloc().
9799 *) Reorganization of data structures associated with a given
9800 request to eliminate use of global variables and the troublesome
9801 unmunge_name function (used in NCSA and early Apache releases to
9802 attempt to determine the URI which mapped to a given filename
9803 --- a difficult proposition, given that it is easy to produce
9804 setups in which multiple URIs map to the same file).
9806 *) Source files renamed and rearranged
9808 *) Very simple pre-forking behavior --- parent process forked off a
9809 fixed number of children, and then just waited for SIGHUP.
9811 *) Other more minor changes too numerous to list.
9813 This release included modified versions of a lot of code from the
9814 Apache 0.6.4 public release, plus an early pre-forking patch
9815 codeveloped by Robert Thau and Rob Hartill.
9817 Changes with Apache 0.7.3 20 Jun 1995
9819 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9820 were incorporated by Rob Hartill on the main branch while Robert Thau
9821 worked on the Shambhala rewrite above. Most were merged into the
9822 Shambala architecture after Apache 0.8.0.
9824 Changes with Apache 0.6.4 13 May 1995
9826 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9829 Changes with Apache 0.5.1 10 Apr 1995
9831 Changes with Apache 0.4 02 Apr 1995
9833 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
9836 Changes with Apache 0.3 24 Mar 1995
9838 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
9841 Changes with Apache 0.2 18 Mar 1995
9843 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
9844 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
9845 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
