3 Changes with Apache 2.0.41
5 *) Allow AddOutputFilterByType to add multiple filters per directive.
8 *) Remove warnings with Sun's Forte compiler. [Justin Erenkrantz]
10 *) Fixed mod_disk_cache's generation of 304s
11 [Kris Verbeeck <Kris.Verbeeck@ubizen.com>]
13 *) Add support for using fnmatch patterns in the final path
14 segment of an Include statement (eg.. include /foo/bar/*.conf).
15 and remove the noise on stderr during config dir processing.
16 [Joe Orton <jorton@redhat.com>]
18 *) mod_cache: cache_storage.c. Add the hostname and any request
19 args to the key generated for caching. This provides a unique
20 key for each virtual host and for each request with unique
21 args. [Paul J. Reder, args code provided by Kris Verbeeck]
23 *) mod_cache: Do not cache responses to GET requests with query
24 URLs if the origin server does not explicitly provide an
25 Expires header on the response (RFC 2616 Section 13.9)
26 [Kris Verbeeck krisv@be.ubizen.com]
28 *) Fix memory leak in core_output_filter. [Justin Erenkrantz]
30 *) Rewrite of aaa modules to an authn/authz model.
31 [Dirk-Willem van Gulik, Justin Erenkrantz]
33 *) Update OpenSSL detection to work on Darwin.
34 [Sander Temme <sctemme@covalent.net>]
36 *) Update the xslt and css to give the documentation a more
38 [André Malo <nd@perlig.de>, Gernot Winkler <greh@o3media.de>]
40 *) Fix some bucket memory leaks in the chunking code
41 [Joe Schaefer <joe+apache@sunstarsys.com>]
43 *) Add ModMimeUsePathInfo directive. [Justin Erenkrantz]
45 *) mod_cache: added support for caching streamed responses (proxy,
46 CGI, etc) with optional CacheMaxStreamingBuffer setting [Brian Pane]
48 *) Add image/x-icon to httpd.conf PR 10993.
49 [Ian Holsman, Peter Bieringer <pb@bieringer.de>]
51 *) Fix FileETags none operation. PR 12207.
52 [Justin Erenkrantz, Andrew Ho <andrew@tellme.com>]
54 *) Restored the experimental leader/followers MPM to working
55 condition and converted its thread synchronization from
56 mutexes to atomic CAS. [Brian Pane]
58 *) Fix Logic on non-html file removal in mod_deflate
59 [Kris Verbeeck <Kris.Verbeeck@ubizen.com>]
61 *) Fix "ab -g"'s truncated year: the last digit was cut off.
62 [Leon Brocard <acme@astray.com>]
64 *) mod_rewrite can now sets cookies in err_headers, uses the correct
65 expiry date, and can now set the path as well
67 [Ian Holsman / Rob Cromwell <apachechangelog@robcromwell.com>]
69 *) The content-length filter no longer tries to buffer up
70 the entire output of a long-running request before sending
71 anything to the client. [Brian Pane]
73 *) Win32: Lower the default stack size from 1MB to 256K. This will
74 allow around 8000 threads to be started per child process.
75 'EDITBIN /STACK:size apache.exe' can be used to change this
76 value directly in the apache.exe executable.
79 *) Win32: Implement ThreadLimit directive in the Windows MPM.
82 *) Remove CacheOn config directive since it is set but never checked.
83 No sense wasting cycles on unused code. Besides, the only truly
84 bug free code is deleted code. :) [Paul J. Reder]
86 *) BufferLogs are now run-time enabled, and the log_config now has 2 new
87 callbacks to allow a 3rd party module to actually do the writing of the
88 log file [Ian Holsman]
90 *) Correct ISAPIReadAheadBuffer to default to 49152, per mod_isapi docs.
91 [André Malo, Astrid Keßler <kess@kess-net.de>]
93 *) Fix Segfault in mod_cache. [Kris Verbeeck <Kris.Verbeeck@ubizen.com>]
95 *) Fix a null pointer dereference in the merge_env_dir_configs
96 function of the mod_env module. PR 11791
99 *) New option to ServerTokens 'maj[or]'. Only show the major version
100 Also Surfaced this directive in the standard config (default FULL)
103 *) Change mod_rewrite to use apr-util's dbm support for dbm rewrite
104 maps. The dbm type (e.g., ndbm, gdbm) can be specified on the
105 RewriteMap directive. PR 10644 [Jeff Trawick]
107 *) Fixed mod_rewrite's RewriteMap prg: support so that request/response
108 pairs will no longer get out of sync with each other. PR 9534
111 *) Fixes required to get quoted and escaped command args working in
112 mod_ext_filter. PR 11793 [Paul J. Reder]
114 *) mod-proxy: handle proxied responses with no status lines
115 [JD Silvester <jsilves@uwo.ca>, Brett Huttley <brett@huttley.net>]
117 *) Fix bug where environment or command line arguments containing
118 non-ASCII-7 characters would cause the Win32 child process creation
119 to fail. PR 11854 [William Rowe]
121 *) Bug #11213.. make module loading error messages more informative
122 [Ian Darwin <Ian779@darwinsys.com>]
124 *) thread safety & proxy-ftp [Alexey Panchenko alexey@liwest.ru, Ian Holsman]
126 *) mod_disk_cache works much better. This module should still
127 be considered experimental. [Eric Prud'hommeaux]
129 *) Performance improvement for keepalive requests: when setting
130 aside a small file for potential concatenation with the next
131 response on the connection, set aside the file descriptor rather
132 than copying the file into the heap. [Brian Pane]
134 Changes with Apache 2.0.40
136 *) SECURITY: [CAN-2002-0661] Close a very significant security hole that
137 applies only to the Win32, OS2 and Netware platforms. Unix was not
138 affected, Cygwin may be affected. Certain URIs will bypass security
139 and allow users to invoke or access any file depending on the system
140 configuration. Without upgrading, a single .conf change will close
141 the vulnerability. Add the following directive in the global server
142 httpd.conf context before any other Alias or Redirect directives;
143 RedirectMatch 400 "\\\.\."
144 Reported by Auriemma Luigi <bugtest@sitoverde.com>.
147 *) SECURITY: Close a path-revealing exposure in multiview type
148 map negotiation (such as the default error documents) where the
149 module would report the full path of the typemapped .var file when
150 multiple documents or no documents could be served based on the mime
151 negotiation. Reported by Auriemma Luigi <bugtest@sitoverde.com>.
152 [CAN-2002-0654] [William Rowe]
154 *) SECURITY: Close a path-revealing exposure in cgi/cgid when we
155 fail to invoke a script. The modules would report "couldn't create
156 child process /path-to-script/script.pl" revealing the full path
157 of the script. Reported by Jim Race <jrace@qualys.com>.
158 [CAN-2002-0654] [Bill Stoddard]
160 *) Set aside the apr-iconv and apr_xlate() features for the Win32
161 build of 2.0.40 so development can be completed. A patch, from
162 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
163 will be available for those that wish to work with apr-iconv.
166 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
167 chain. [Peter Van Biesen <peter.vanbiesen@vlafo.be>]
169 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
170 set to 1, so we can exclude things from the general case with
171 browsermatch. [Ian Holsman, Andre Schild <A.Schild@aarboard.ch>]
173 *) Accept multiple leading /'s for requests within the DocumentRoot.
174 PR 10946 [William Rowe, David Shane Holden <dpejesh@yahoo.com>]
176 *) Solved the reports of .pdf byterange failures on Win32 alone.
177 APR's sendfile for the win32 platform collapses header and trailer
178 buffers into a single buffer. However, we destroyed the pointers
179 to the header buffer if a trailer buffer was present. PR 10781
182 *) mod_ext_filter: Add the ability to enable or disable a filter via
183 an environment variable. Add the ability to register a filter of
184 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
186 *) Restore the ability to specify host names on Listen directives.
187 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh@yahoo.com>]
189 *) When deciding on the default address family for listening sockets,
190 make sure we can actually bind to an AF_INET6 socket before
191 deciding that we should default to AF_INET6. This fixes a startup
192 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
194 *) Replace usage of atol() to parse strings when we might want a
195 larger-than-long value with apr_atoll(), which returns long long.
196 This allows HTTPD to deal with larger files correctly.
197 [Shantonu Sen <ssen@apple.com>]
199 *) mod_ext_filter: Ignore any content-type parameters when checking if
200 the response should be filtered. Previously, "intype=text/html"
201 wouldn't match something like "text/html;charset=8859_1".
204 *) mod_ext_filter: Set up environment variables for external programs.
205 [Craig Sebenik <craig@netapp.com>]
207 *) Modified the HTTP_IN filter to immediately append the EOS (end of
208 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
209 the caller to determine that no content remains without prefetching
210 additional POST body. [William Rowe]
212 *) Get proxy ftp to work over IPv6. [Shoichi Sakane <sakane@kame.net>]
214 *) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml@suse.de>]
216 *) Update SuSE layout. [Peter Poeml <poeml@suse.de>]
218 *) Changes to the internationalized error documents:
219 Comment them out in the default config file to make the default
220 install as simple as possible; Correct the english 500 error to
221 be more understandable; Add a Swedish translation.
222 [Thomas Sjogren <thomas@northernsecurity.net>,
223 Erik Abele <erik@codefaktor.de>, Rich Bowen, Joshua Slive]
225 *) Increase the limit on file descriptors per process in apachectl.
228 *) Fix a dependency error when building ApacheMonitor, so that Win32
229 and MSVC now trust that the project is current (when it is).
230 [James Cox <imajes@php.net>]
232 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
233 [Arthur P. Smith <apsmith@aps.org>, Jeff Trawick]
235 *) APR-Util Renames pending have been completed [Thom May]
237 *) Performance improvements for the code that reads request
238 headers (ap_rgetline_core() and related functions) [Brian Pane]
240 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
241 to configure the maximum amount of memory the allocators will
242 hold on to for reuse. Anything over the MaxMemFree threshold
243 will be free()d. This directive is useful when uncommon large
244 peaks occur in memory usage. It should _not_ be used to mask
245 defective modules' memory use. [Sander Striker]
247 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
248 scripts would not result in a truncated response.
249 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
251 *) Add a filter_init parameter to the filter registration functions
252 so that a filter can execute arbitrary code before the handlers
253 are invoked. This resolves a problem where mod_include requests
254 would incorrectly return a 304. [Justin Erenkrantz]
256 *) Fix a long-standing bug in 2.0, CGI scripts were being called
257 with relative paths instead of absolute paths. Apache 1.3 used
258 absolute paths for everything except for SuExec, this brings back
259 that standard. [Ryan Bloom]
261 *) Fix infinite loop due to two HTTP_IN filters being present for
262 internally redirected requests. PR 10146. [Justin Erenkrantz]
264 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
267 *) Fix mod_ext_filter to look in the main server for filter definitions
268 when running in a vhost if the filter definition is not found in
269 the vhost. PR 10147 [Jeff Trawick]
271 *) Support WinNT CGI invocation through ScriptInterpreterSource
272 'registry' for script interpreter paths and names with non-ascii
273 characters in the executable filepath. [William Rowe]
275 *) Support the -w flag on to keep the Win32 console open on error.
278 *) Normalize the hostname value in the request_rec to all-lowercase
279 [Perry Harrington <pedward@webcom.com>]
281 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
282 extended characters (non US-ASCII) in non-utf8 format. This brings
283 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
284 to the cgi application itself. [William Rowe]
286 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
287 modules to bring them up to the current apr/apr-util APIs.
290 *) Fix segfault in mod_mem_cache most frequently observed when
291 serving the same file to multiple clients on an MP machine.
294 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
295 [Brian Degenhardt <bmd@mp3.com>, Ian Holsman]
297 *) Fix perchild to work with apachectl by adding -k support to perchild.
298 PR 10074 [Jeff Trawick]
300 *) Fix a silly htpasswd.c logic error that incorrectly reported that
301 both -c and -n had been used. PR 9989 [Cliff Woolley]
303 *) Fixed a mod_include error case in which no HTTP response was sent
304 to the client if an shtml document contained an unterminated SSI
305 directive [Brian Pane]
307 *) Improve ap_get_client_block implementation by using APR-util brigade
308 helper functions and relying on current filter assumptions.
311 Changes with Apache 2.0.39
313 *) Fixed a build problem in htpasswd.c on Win32.
314 [Guenter Knauf <eflash@gmx.net>, Cliff Woolley]
316 Changes with Apache 2.0.38
318 *) Rewrite htpasswd to use APR. The removes the annoying warning about
319 tmpnam being unsafe. [Ryan Bloom]
321 *) We must set the MIME-type for .shtml files to text/html if we want them
322 to be parsed for SSI tags. Add the config for that to the default
323 config file so that it is easier to enable .shtml parsing.
324 [Dave Dyer <ddyer@real-me.net>]
326 *) Fixed a problem with 'make install' on ReliantUnix.
327 [Jean-frederic Clere <jfrederic.clere@fujitsu-siemens.com>]
329 *) Make the default_handler catch all requests that aren't served by
330 another handler. This also gets us to return a 404 if a directory
331 is requested, there is no DirectoryIndex, and mod_autoindex isn't
332 loaded. [Justin Erenkrantz]
334 *) Fixed the handling of nested if-statements in shtml files.
337 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
338 into a directory different from the one that was configured. This
339 also mirrors the root= feature from 1.3. We cannot use prefix=,
340 because both APR and APR-util resolve their installation paths at
341 configuration time. This means that there is no variable prefix
342 to replace. [Andreas Hasenack <andreas@netbank.com.br>]
344 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
345 These levels of AIX don't have a thundering herd problem with
346 accept(). [Jeff Trawick]
348 *) prefork MPM: Ignore mutex errors during graceful restart. For
349 certain types of mutexes (particularly SysV semaphores), we
350 should expect to occasionally fail to obtain or release the
351 mutex during restart processing. [Jeff Trawick]
353 *) Fix install-bindist.sh so that it finds any perl instead of just
354 early perl 5.x versions. This is consistent with a build/install
355 from source, and it allows the perl scripts installed by a bindist
356 to work on systems with perl 5.6. [Jeff Trawick]
358 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
359 Tru64 (and probably some other platforms). [Jeff Trawick]
361 *) Allow CGI scripts to return their Content-Length. This also fixes a
362 hang on HEAD requests seen on certain platforms (such as FreeBSD).
365 *) Added log rotation based on file size to the RotateLog support
366 utility. [Brad Nicholes]
368 *) Fix some casting in mod_rewrite which broke random maps.
369 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
371 Changes with Apache 2.0.37
373 *) allow POST method over SSL when per-directory client cert
374 authentication is used with 'SSLOptions +OptRenegotiate' enabled
375 and a client cert was found in the ssl session cache.
377 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
378 session cache when there is no cert chain in the cache. prior to
379 the fix this situation would result in a FORBIDDEN response and
380 error message "Cannot find peer certificate chain"
383 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
384 one was already sent. PR 9644 [Jeff Trawick]
386 *) Fix the display of the default name for the mime types config
387 file. PR 9729 [Matthew Brecknell <mbrecknell@orchestream.com>]
389 *) Fix the working directory *for WinNT/2K/XP services only* to
390 change to the Apache directory (one level above the location
391 of Apache.exe, in the case that Apache.exe resides in bin/.)
392 Solves the case of ServerRoot /foo paths where /foo was not
393 on the same drive as /winnt/system32. [William Rowe]
395 *) Make 2.0's "AcceptMutex" startup message now "completely"
396 match how 1.3 does it. [Jim Jagielski]
398 *) Implement a fixed size memory cache using a priority queue
401 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
402 querying certain other variables from config_vars.mk. PR 9316
405 *) Added the "detached" attribute to the cgi_exec_info_t internals
406 so that Win32 and Netware won't create a new window or console
407 for each CGI invoked. PR 8387
408 [Brad Nicholes, William Rowe]
410 *) Consolidated the command line parameters and attributes that are
411 manipulated by the optional function ap_cgi_build_command() in
412 mod_cgi into a single structure.
415 *) Get rid of uninitialized value errors with "apxs -q" on certain
416 variables. [Stas Bekman <stas@stason.org>]
418 *) Fix apxs to allow it to work when the build directory is somewhere
419 besides server-root/build. PR 8453
420 [Jeff Trawick and a host of others]
422 *) Allow ap_discard_request_body to be called multiple times in the
423 same request. Essentially, ap_http_filter keeps track of whether
424 it has sent an EOS bucket up the stack, if so, it will only ever
425 send an EOS bucket for this request.
426 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
428 *) Remove all special mod_ssl URIs. This also fixes the bug where
429 redirecting (.*) will allow an SSL protected page to be viewed
430 without SSL. [Ryan Bloom]
432 *) Fix the binary build install script so that the build logic
433 created by "apxs -g" will work when the user has a binary
434 build. [Jeff Trawick]
436 *) Allow instdso.sh to work with full paths to the shared module.
439 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
440 in module for NetWare [Brad Nicholes]
442 *) Changed cgi and piped log behavior to accept 65536 characters
443 on Win32 (matching Linux) before deadlocking between outputing
444 client stdin, slurping the output from stdout and then the stderr
445 stream. PR 8179 [William Rowe]
447 *) Fixed Win32 wintty.exe support to assure the window title is valid.
448 Elimiates possible gpfault or garbage title without the -t option.
451 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
452 brigades and input filters. [Justin Erenkrantz]
454 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
455 body. [Justin Erenkrantz]
457 *) NetWare: Piping log entries through RotateLogs using the
458 CustomLogs directive is finally supported now that we have
459 the pipes and spawning functionality working.
462 *) Detect overflow when reading the hex bytes forming a chunk line.
465 *) Allow RewriteMap prg:'s to take command-line arguments. PR 8464.
466 [James Tait <JTait@wyrddreams.demon.co.uk>]
468 *) Correctly return 413 when an invalid chunk size is given on
469 input. Also modify ap_discard_request_body to not do anything
470 on sub-requests or when the connection will be dropped.
473 *) Fix the TIME_* SSL var lookups to be threadsafe. PR 9469.
476 *) Ensure that apr_brigade_write() flushes in all of the cases that
477 it should to avoid conditions in some modules that could cause
478 large amounts of data to be buffered. [Cliff Woolley]
480 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
481 stripping the content_type from cached responses.
484 *) apachectl passes through any httpd options. Note: apachectl
485 should be used in preference to httpd since it ensures that any
486 appropriate environment variables have been set up.
489 *) Fix the combination of mod_cgid, mod_setuexec, and mod_userdir.
490 PR 7810 [Colm MacCarthaigh <colmmacc@redbrick.dcu.ie>]
492 *) Fix suexec execution of CGI scripts from mod_include.
493 PR 7791, 8291 [Colm MacCarthaigh <colmmacc@redbrick.dcu.ie>]
495 *) Fix segfaults at startup on some platforms when mod_auth_digest,
496 mod_suexec, or mod_ssl were used as DSO's due to the way they
497 were tracking the current init phase since DSO's get completely
498 unloaded and reloaded between phases. PR 9413.

507 [Yoshiki Hayashi, Joshua Slive]
509 *) Fix a file permissions problem which prevented mod_disk_cache
510 from working on Unix. [Jeff Trawick]
512 *) Add "-k start|restart|graceful|stop" support to httpd for the Unix
513 MPMs. These have semantics very similar to the old apachectl
514 commands of the same name. [Justin Erenkrantz, Jeff Trawick]
516 *) Make sure that the runtime dir is created by make install.
517 PR 9233. [Jeff Trawick]
519 *) Fix an unusual set of ./configure arguments that could cause
520 mod_http to be built as a DSO, which it currently doesn't
522 [Cliff Woolley, Robin Johnson <robbat2@orbis-terrarum.net>]
524 *) Win32: Fix bug in apr_sendfile() that caused incorrect operation
525 of the %X, %b and %B logformat options. PR 8253, 8996.
528 *) If content-encoding is already present, do not run deflate (PR 9222)
529 [Kazuhisa ASADA <kaz@asada.sytes.net>]
531 *) The APLOG_NOERRNO flag to ap_log_[r]error() is now deprecated.
532 It is currently ignored and it will be removed in a future release
533 of Apache. [Jeff Trawick]
535 *) Removed documentation references to the no-longer-supported
536 "make certificate" feature of mod_ssl for Apache 1.3.x. Test
537 certificates, if truly desired, can be generated using openssl
538 commands. PR 8724. [Cliff Woolley]
540 *) Remove SSLLog and SSLLogLevel directives in favor of having
541 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
543 *) OS/390: LIBPATH no longer has to be manually uncommented in
544 envvars to get apachectl to set up httpd properly. [Jeff Trawick]
546 *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
547 may now be specified to the <File/Directory > container, rather
548 than by vhost. [William Rowe]
550 *) mod_isapi: Experimental support for faux async support for ISAPI
551 modules. [William Rowe]
553 *) mod_isapi: Major refactoring of the code to rely on apr internals
554 rather than MS APIs (using our own mod_isapi.h headers for ISAPI
555 symbol definitions.) [William Rowe]
557 *) mod_isapi: Fixed the return string length from GetServerVariable
558 callback, it was not including the trailing null in the consumed
559 buffer size. This was particularly bad for Delphi 6.0 users.
560 PR 8934 [Sebastian Hantsch <sebastian.hantsch@gmx.de>]
562 *) Fixed Win32 builds for Microsoft VisualStudio 7.0 (.net).
565 *) Make apxs look in the correct directory for envvars. It was
566 broken when sbindir != bindir. PR 8869
567 [Andreas Sundström <sunkan@zappa.cx>]
569 *) Fix mod_deflate corruption when using multiple buckets. PR 9014.
570 [Asada Kazuhisa <kaz@asada.sytes.net>]
572 *) Performance enhancements for access logger when using
573 default timestamp formatting [Brian Pane]
575 *) Added EnableMMAP config directive to enable the server
576 administrator to disable memory-mapping of delivered files
577 on a per-directory basis. [Brian Pane]
579 *) Performance enhancements for mod_setenvif [Brian Pane]
581 *) Fix a mod_ssl build problem on OS/390. [Jeff Trawick]
583 *) Fixed If-Modified-Since on Win32, which would give false positives
584 because of the sub-second resolution of file timestamps on that

617 were accessing scoreboard slots still in use by active threads in
618 the the old process. [Bill Stoddard]
620 Changes with Apache 2.0.36
622 *) Fix some minor formatting issues with ab. Part of this is
623 in reference to PR 8544, the rest I noticed while testing
624 the PR fix. [Paul J. Reder]
626 *) Fix a case where an invalid pass phrase is entered and an
627 error message is given, but the prompt is not shown again.
628 This left the user in an ambiguous state. PR 8320 [Paul J. Reder]
630 *) Close sockets on worker MPM when doing a graceless restart.
633 *) Reverted a minor optimization in mod_ssl.c that used the vhost ID
634 as the session id context rather that a MD5 hash of that vhost ID,
635 because it caused very long vhost id's to be unusable with mod_ssl.

638 *) Fix the link to the description of the CoredumpDirectory
639 directive in the server-wide document. PR 8643. [Jeff Trawick]
641 *) Fixed SHMCB session caching. [Aaron Bannert, Cliff Woolley]
643 *) Synced with remaining changes from mod_ssl 2.8.8-1.3.24:
644 - Avoid SIGBUS on sparc machines with SHMCB session caches
645 - Allow whitespace between the pipe and the name of the
646 program in SSLLog "| /path/to/program". [Cliff Woolley]
648 *) Introduce mod_ext_filter and mod_deflate experimental modules
649 to the Win32 build (zlib sources must be in srclib\zlib.)
652 *) Changes to the worker MPM's queue management and thread
653 synchronization code to reduce mutex contention [Brian Pane]
655 *) Don't install *.in configuration files since we already install
656 *-std.conf files. [Aaron Bannert]
658 *) Many improvements to the threadpool MPM. [Aaron Bannert]
660 *) Fix subreqs that are promoted via fast_redirect from having invalid
661 frec->r structures. This would cause subtle errors later on in
662 request processing such as seen in PR 7966. [Justin Erenkrantz]
664 *) More efficient pool recycling logic for the worker MPM [Brian Pane]
666 *) Modify the worker MPM to not accept() new connections until
667 there is an available worker thread. This prevents queued
668 connections from starving for processing time while long-running
669 connections were hogging all the available threads. [Aaron Bannert]
671 *) Convert the worker MPM's fdqueue from a LIFO back into a FIFO.
674 *) Get basic HTTP proxy working on EBCDIC machines. [Jeff Trawick]

712 ap_uname2id. [Scott Lamb <slamb@slamb.org>]
714 *) Fix AcceptPathInfo. PR 8234 [Cliff Woolley]
716 *) SECURITY: Added the APLOG_TOCLIENT flag to ap_log_rerror() to
717 explicitly tell the server that warning messages should be sent
718 to the client in addition to being recorded in the error log.
719 Prior to this change, ap_log_rerror() always sent warning
720 messages to the client. In one case, a faulty CGI script caused
721 the server to send a warning message to the client that contained
722 the full path to the CGI script. This could be considered a
723 minor security exposure. [Bill Stoddard]
725 *) mod_autoindex output when SuppressRules was specified would
726 omit the first carriage return so the first item in the list
727 would appear to the right of the column headings instead of
728 underneath them. PR 8016 [David Shane Holden <dpejesh@yahoo.com>]
730 *) Moved the call to apr_mmap_dup outside the error branch so
731 that it would actually get called. This fixes a core dump
732 at init everytime you use the MMapFile directive. PR 8314
735 *) Trigger an error when a LoadModule directive attempts to
736 load a module which is built-in. This is a common error when
737 switching from a DSO build to a static build. [Jeff Trawick]
739 *) Change instdso.sh to use libtool --install everywhere and then
740 clean up some stray files and symlinks that libtool leaves around
741 on some platforms. This gets subversion building properly since
742 it needed a re-link to be performed by libtool at install time,
743 and the old instdso.sh logic to simply cp the DSO didn't handle
744 that requirement. [Sander Striker]
746 *) Allow VPATH builds to succeed when configured from an empty

753 located in server/mpm/experimental. [Justin Erenkrantz]
755 *) Fix segfault in mod_mem_cache when garabge collecting an expired
756 cache entry. [Bill Stoddard]
758 *) Introduced -E startup_logfile_name option to httpd to allow admins
759 to begin logging errors immediately. This provides Win32 users
760 an alternative to sending startup errors to the event viewer, and
761 allows other daemon tool authors an alternative to logging to stderr.
764 *) Fix subreqs with non-defined Content-Types being served improperly.
767 *) Merge in latest GNU config.guess and config.sub files. PR 7818.
770 *) Move 100 - Continue support to the HTTP_IN filter so that filters

799 *) Win32: Fix problem that caused rapid performance degradation
800 when number of connecting clients exceeded ThreadsPerChild.
803 *) Fixed a segfault parsing large SSIs on non-mmap systems.
806 *) Proxy was bombing out every second keepalive request, caused by a
807 stray CRLF before the second response's status line. Proxy now
808 tries to read one more line if it encounters a CRLF where it
809 expected a status. PR 10010 [Graham Leggett]
811 *) Deprecated the apr_lock.h API. Please see the following files
812 for the improved thread and process locking and signaling:
813 apr_proc_mutex.h, apr_thread_mutex.h, apr_thread_rwlock.h,
814 apr_thread_cond.h, and apr_global_mutex.h. [Aaron Bannert]
816 *) Change mod_status to use scoreboard accessor functions so it can
817 be used in any MPM without having to be recompiled.
818 [Ryan Morgan <rmorgan@covalent.net>]
820 *) Fix parsing of some AP_DECLARE_DATA declarations so that the filter

847 "<!--#" occurs at the very end of a bucket
848 [Paul Reder, Brian Pane]
850 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
851 cause the Apache parent process to run in the foreground (similar to
852 -DNO_DETACH except that it doesn't switch session ids).
855 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
856 for those platforms that support it. If using the default
857 implementation, this is between pthread and sysvsem in priority.
858 This implies it's the new default for Darwin. [Jim Jagielski]
860 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
861 environment variables in the envvars file. [Jeff Trawick]
863 *) worker MPM: Don't create a listener thread until we have a worker
864 thread. Otherwise, in situations where we'll have to wait a while
865 to take over scoreboard slots from a previous generation, we'll be
866 accepting connections we can't process yet. [Jeff Trawick]
868 *) Allow worker MPM to build on systems without pthread_kill().
869 [Pier Fumagalli, Jeff Trawick]
871 *) Prevent ap_add_output_filters_by_type from being called in
872 ap_set_content_type if the content-type hasn't changed.

876 API change in 2.0.34. [Cliff Woolley]
878 *) Don't allow initialization to succeed if we can't get a socket
879 corresponding to one of the Listen statements. [Jeff Trawick]

883 *) Allow all Perchild directives to accept either numerical UID/GID
884 or logical user/group names. [Scott Lamb <slamb@slamb.org>]
886 *) Make Perchild compile cleanly and serve pages again. [Ryan Bloom]
888 *) implement ssl proxy to support ProxyPass / https:// and the

894 *) Made AB's use of the Host: header rfc2616 compliant
895 by Taisuke Yamada <tai@iij.ad.jp> [Dirk-Willem van Gulik].
897 *) The old, legacy (and unused) code in which the scoreboard was totally
898 and completely contained in a file (SCOREBOARD_FILE) has been
899 removed. This does not affect scoreboards which are *mapped* to
900 files using named-shared-memory. [Jim Jagielski]
902 *) Change bucket brigades API to allow a "bucket allocator" to be
903 passed in at certain points. This allows us to implement freelists
904 so that we can stop using malloc/free so frequently.

919 quick handlers to optionally do a lookup rather than actually
920 serve content. This is the first of several changes required fix
921 several problems with how quick handlers work with subrequests.
924 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]

935 [Linus Walleij <triad@df.lth.se>, Justin Erenkrantz]
937 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
939 *) When a proxied site was being served, Apache was replacing
940 the original site Server header with it's own, which is not
941 allowed by RFC2616. Fixed. [Graham Leggett]
943 *) Fix a mod_cgid problem that left daemon processes stranded
944 in some server restart scenarios. [Jeff Trawick]
946 *) Added exp_foo and rel_foo variables to config_vars.mk for
947 all Apache and Autoconf path variables (like --sysconfdir,
948 --sbindir, etc). exp_foo is the "expanded" version, which means
949 that all internal variable references have been interpolated.
950 rel_foo is the same as $exp_foo, only relative to $prefix if they
951 share a common path. [Aaron Bannert]
953 *) Fix some restart/terminate problems in the worker MPM. Don't
954 drop connections during graceful restart. [Jeff Trawick]
956 *) Change the header merging behaviour in proxy, as some headers
957 (like Set-Cookie) cannot be unmerged due to stray commas in
958 dates. [Graham Leggett]
960 *) Be more vocal about what AcceptMutex values we allow, to make

980 *) Fix for virtual host processing where the requested hostname
981 has a '.' at the end (PR 9187) [Ryan Cruse <ryan@estara.com>]
983 *) mod_dav's APIs for REPORT response handling was changed so that
984 providers can generate the content directly into the output filter
985 stack, rather than buffering the response into memory. [Greg Stein]
987 *) Fix a hang condition with graceful restart and prefork MPM
988 in the situation where MaxClients is very high but
989 much fewer servers are actually started at the time of the
990 restart. [Jeff Trawick]
992 *) Small performance fixes for mod_include [Brian Pane]

997 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
998 according to sun people solaris 8+ doesn't have a thundering
999 herd problem [Ian Holsman]
1001 *) Allow URIs specifying CGI scripts to include '/' at the end
1002 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
1003 which ignore '/' at the end of the names of non-directories).

1022 preprocessor directive in mod_file_cache)
1025 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
1026 preprocessor directive in mod_file_cache)

1032 *) Add a missing manualdir entry in the Debian config.layout.
1033 [Thom May <thom@planetarytramp.net>]
1035 *) Stop installing libtool for APR and tell APR where it should place
1036 its copy of libtool (via our installbuildpath layout variable).
1039 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
1040 when reading from a remote HTTP server in proxy. [Graham Leggett]
1042 *) Modify receive/send loop in proxy_http and proxy_ftp so that
1043 should it be necessary, the remote server socket is closed before
1044 transmitting the last buffer (set by ProxyIOBufferSize) to the
1045 client. This prevents the backend server from being forced to hang
1046 around while the last few bytes are transmitted to a slow client.
1047 Fix the case where no error checking was performed on the final
1048 brigade in the loop. [Graham Leggett]
1050 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
1051 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
1052 hours. [Graham Leggett, Bill Stoddard]
1054 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
1055 for a undefined variable. [Ian Holsman]
1057 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
1058 when we can't get a socket in the specified address family. We may
1059 have gotten back an IPv6 address first and yet our system is not
1060 configured to allow IPv6 sockets. [Jeff Trawick]

1067 [Dirk-Jan Faber <dirk-jan@selwerd.nl>, Aaron Bannert,
1068 Thom May <thom@planetarytramp.net>]
1070 *) Rename the filter ordering priorities. The recent filtering fixes
1071 have showcased problems with their usage. Therefore, we need to
1072 rename them to increase the clarity. (CONTENT->RESOURCE,
1073 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
1075 Changes with Apache 2.0.33
1077 *) Fix a problem in the new --enable-layout functionality where
1078 it wouldn't allow overrides from variables like --prefix,
1079 --bindir, etc. [Thom May <thom@planetarytramp.net>]

1085 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
1086 [Thom May <thom@planetarytramp.net>]
1088 *) Change mod_ssl to always do a full startup/teardown on restarts.
1089 this allows mod_ssl to be added to a server that is already
1090 running and makes it possible to add/change certs/keys after the
1091 server has been started. [Doug MacEachern]
1093 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
1094 This pipe must be a bidirectional 'console' style relay, which
1095 mod_ssl prints all prompts to the pipe's stdin, and reads the
1096 passphrases from the pipe's stdout. [William Rowe]
1098 *) Fix bug where --sysconfdir and --localstatedir were being
1099 ignored. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
1102 *) Fix --enable-layout to work again. Caution: When specifying
1103 --enable-layout, common arguments like --prefix, --exec-prefix,
1104 etc. will be ignored and the settings from the layout will be
1105 used instead. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
1108 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
1109 regex pattern matching for the determination of which requests
1110 to use the remote proxy for. [Jim Jagielski]
1112 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
1114 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
1115 cruft in piped logs and rewritemap child processes.
1118 *) All instances of apr_lock_t have been removed and converted
1119 to one of the following new lock APIs: apr_thread_mutex.h,
1120 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
1121 use the apr_lock.h API, as the old API will soon be deprecated.
1124 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.

1127 *) mod-include: make it handle flush'es and fix the 'false-alarm'
1128 [Justin Erenkrantz, Brian Pane, Ian Holsman]
1130 *) ap_get_*_filter_handle() functions to allow 3rd party modules

1132 lookup when adding filters to a request (via ap_add_*_filter_handle())
1133 [Ryan Morgan <rmorgan@covalent.net>]
1135 *) Fix for multiple file buckets on Win32, where the first file
1136 bucket would cause the immediate closure of the socket on any
1137 non-keepalive requests. [Ryan Morgan <rmorgan@covalent.net>]
1139 *) Correct Win32 failure of mmap of a segment beyond start of the
1140 file; fixes large SSL and similar transfers. [William Rowe]
1143 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
1144 multi-process mode to not "daemonize" while detaching from the
1145 controlling terminal. This is necessary for Apache to work with
1146 process-management tools like AIX's "System Resource Controller"
1147 as well as Dan Bernstein's "daemontools".
1148 [Jos Backus <josb@cncdsl.com>, Aaron Bannert]
1150 *) Convert mod_auth_digest to use the new apr_global_mutex_t
1151 type. [Aaron Bannert]
1153 *) fix bug in mod-include where it wouldn't send a unmatched
1154 part if it was at the end of a bucket [Ian Holsman]
1156 *) worker MPM: Improve logging of errors with the interface between
1157 the listener thread and worker threads. [Jeff Trawick]
1159 *) Some browsers ignore cookies that have been merged into a
1160 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
1161 are now unmerged in the http proxy before being sent to the
1162 client. [Graham Leggett]
1164 *) Fix a problem with proxy where each entry of a duplicated
1165 header such as Set-Cookie would overwrite and obliterate the
1166 previous value of the header, resulting in multiple header
1167 values (like cookies) going missing.
1168 [Graham Leggett, Joshua Slive]
1170 *) Add the server-limit and thread-limit values to the scoreboard

1179 *) Win32: Fix bug in mod_status with displaying "Restart Time"
1180 and "Server uptime".
1183 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
1185 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
1187 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
1188 [David MacKenzie <djm@pix.net>]
1190 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
1191 [David MacKenzie <djm@pix.net>]
1193 *) Fix segfault and display error when SSLMutex file can not be
1194 created. [Adam Sussman <myddryn@vishnu.vidya.com>]
1196 *) Add reference counting to mod_mem_cache cache objects to
1197 better manage removing objects from the cache.
1200 *) Change the verbage on the ScoreBoardFile in our default configs.
1201 Also change the default to be commented out (unspecified) so we
1202 get anonymous shared memory by default. [Aaron Bannert]
1204 *) Implement new ScoreBoardFile directive logic. This affects how
1205 we create the scoreboard's shared memory segment. If the directive
1206 is present, a name-based segment is created. If the directive is
1207 not present, first an anonymous segment is created, and if that
1208 fails, a name-based segment is created from a file of the name
1209 DEFAULT_SCOREBOARD. This gives third-party applications the
1210 ability to access our scoreboard. [Aaron Bannert]
1212 *) Allow mod_deflate to work with non-GET requests and properly send
1213 Content-Lengths. [Sander Striker <striker@apache.org>]
1215 *) Fix ap_directory_merge() to correctly merge configs when there is
1216 no <Directory /> block. [Justin Erenkrantz, William Rowe]
1218 *) Remove spurious debug messsages that are normal under HTTP
1219 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
1221 *) Fix a bug in mod_cgid that would prevent proper shutdown death
1222 of the cgid process. [Aaron Bannert]
1224 *) Add signal handling back in to the worker MPM for the one_process
1225 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
1227 *) Performance: Reuse per-connection transaction pools in the
1228 worker MPM, rather than destroying and recreating them. [Brian Pane]
1230 *) Remove all signals from the worker MPM's child process. Instead,
1231 the parent uses the Pipe of Death for all communication with the
1232 child processes. [Ryan Bloom]
1234 Changes with Apache 2.0.32
1236 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
1237 default if the directive is not specified. This mirrors older
1238 behavior without changes to the httpd.conf. [William Rowe]
1240 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
1241 the service, mpm and logging code, and bugs in apr_file_open_stderr
1242 and apr_file_dup2 functions. Win2K/XP services have no handles
1243 associated for stdin/out/err, which caused unpredictable behavior
1244 in the prior release. [William Rowe, Bill Stoddard]
1246 *) Win32: simplify the Application Event Log messages, since there isn't
1247 likely to be 'more information in the error log' before an error log
1248 has been opened. [William Rowe]
1250 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
1251 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
1253 *) Win32: apache -k shutdown now behaves like apache -k stop.
1256 *) Fix prefork to not kill the parent if a child hits a resource shortage
1257 on accept(). [Greg Ames]
1259 *) Fix seg faults that occur when what should be the httpd request line
1260 starts with \r\n followed by garbage. [Greg Ames]
1262 *) Allow statically linked support binaries with the new
1263 --enable-static-support flag, and enable this behavior in
1264 the binbuild script. Also add a new --enable-static-htdbm
1265 flag. [Aaron Bannert]
1267 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
1268 do only one stat() call when generating the directory listings.
1271 *) Fix resolve_symlink to save the original symlink name if known.
1274 *) Be a bit more sane with regard to CanonicalNames. If the user has
1275 specified they want to use the CanonicalName, but they have not
1276 configured a port with the ServerName, then use the same port that
1277 the original request used. [Ryan Bloom and Ken Coar]
1279 *) In core_input_filter, check for an empty brigade after
1280 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
1281 client says it will post some data but we get FIN before any
1282 data arrives. [Jeff Trawick]
1284 *) Not being able to bind to the socket is a fatal error. We should
1285 print an error to the console, and return a non-zero status code.
1286 With these changes, all of the Unix MPMs do that correctly.
1289 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
1290 through to CGI scripts. PR 9163
1291 [Brian Reid <breid@customlogic.com>,
1292 Zvi Har'El <rl@math.technion.ac.il>]
1294 *) binbuild.sh: Make sure that we use the expat from our source
1295 tree so that there aren't any surprises on the target machine.
1298 *) mod_cgid: Add retry logic for when the daemon can't fork fast
1299 enough to keep up with new requests. Start using
1300 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
1301 when we can't talk to the daemon. [Jeff Trawick]
1303 *) apxs: LTFLAGS envvar can override default libtool options. Try
1304 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
1305 the covers. [Jeff Trawick]
1307 *) The Location: response header field, used for external
1308 redirect, *must* be an absoluteURI. The Redirect directive
1309 tested for that, but RedirectMatch didn't -- it would allow
1310 almost anything through. Now it will try to turn an abs_path
1311 into an absoluteURI, but it will correctly varf like Redirect
1312 if the final redirection target isn't an absoluteURI. [Ken Coar]
1314 Changes with Apache 2.0.31
1316 *) Create the scoreboard (in the parent) in a global pool context,
1317 so it survives graceful restarts. This fixes a SEGV during
1318 graceful restarts. [Aaron Bannert]
1320 *) Add a timeout option to the proxy code 'ProxyTimeout'
1323 *) FTP directory listings are now always retrieved in ASCII mode.
1324 The FTP proxy properly escapes URI's and HTML in the generated
1325 listing, and escapes the path components when talking to the FTP
1326 server. It is now possible to browse the root directory by using
1327 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
1328 Also, the last path component may contain wildcard characters
1329 '*' and '?', and if they do, a directory listing is created instead
1330 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
1333 *) Added single-listener unserialized accept support to the
1334 worker MPM [Brian Pane]
1336 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
1337 the incoming host header through to the proxied server
1338 [Geoff <g.russell@ieee.org>]
1340 *) New Directive Option for ProxyPass. It now can block a location
1341 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
1343 *) Don't let the default handler try to serve a raw directory. At
1344 best you get gibberish. Much worse things can happen depending
1345 on the OS. [Jeff Trawick]
1347 *) Change the pre_config hook to return a value. Modules can now emit
1348 an error message and then cause the server to quit gracefully during
1349 startup. This required a bump to the MMN. [Aaron Bannert]
1351 *) Fix some unix socket descriptor leaks in the handler side of
1352 mod_cgid (the part that runs in the server process). Whack a
1353 silly "close(-1)" in the handler too. [Jeff Trawick]
1355 *) Change the pre_mpm hook to return a value, so that scoreboard
1356 init errors percolate up to code that knows how to exit
1357 cleanly. This required a bump to the MMN. [Jeff Trawick]
1359 *) Add the socket back to the conn_rec and remove the create_connection
1360 hook. The create_connection hook had a design flaw that did not
1361 allow creating connections based on vhost info. [Bill Stoddard]
1363 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
1364 Resolves the common case of using negotation to resolve the request
1365 /script/foo for /script.cgi/foo. [William Rowe]
1367 *) Added new functions ap_add_(input|output)_filter_handle to
1368 allow modules to bypass the usual filter name lookup when
1369 adding hard-coded filters to a request [Brian Pane]
1371 *) caching should now work on subrequests (still very experimental)
1374 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
1376 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
1379 *) Refactor ap_rgetline so that it does not use an internal brigade.
1380 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
1382 *) Remove mod_auth_db. [Justin Erenkrantz]
1384 *) Do not install unnecessary pcre headers like config.h and internal.h.
1385 [Joe Orton <joe@manyfish.co.uk>]
1387 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
1388 (as it does for a normal request). quick_handled sub-requests now work
1389 in mod-include [Ian Holsman]
1391 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
1392 'CONTENT' one, as it needs to run AFTER all content headers
1394 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
1397 *) Split out blocking from the mode in the input filters.
1400 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
1402 *) Cause Win32 to capture all child-worker process errors in
1403 Apache to the main server error log, until the child can
1404 open its own error logs. [William Rowe]
1406 *) HPUX 11.*: Do not kill the child process when accept()
1407 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
1408 by [madhusudan_mathihalli@hp.com])
1411 *) Fix a problem in the parsing of the <Proxy foo> directive.
1414 *) rewrite of mod_ssl input filter for better performance and less
1415 memory usage [Doug MacEachern]
1417 *) allow quick_handler to be run on subrequests. [Ian Holsman]
1419 *) mod_dav now asks its provider to place content directly into the
1420 filter stack when handling a GET request. The mod_dav/provider
1421 API has changed, so providers need to be updated. [Greg Stein]
1423 *) Clear the output socket descriptor in unixd_accept() to make sure
1424 we don't supply a bogus socket to the caller if the accept fails.
1425 This caused problems with the worker MPM, which tried to process
1426 the returned socket if it was non-NULL. [Brian Pane]
1428 *) Move a check for an empty brigade to the start of core input filter
1429 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
1431 *) Add FileETag directive to allow configurable control of what
1432 data are used to form ETag values for file-based URIs. MMN
1433 bumped to 20020111 because of fields added to the end of
1434 the core_dir_config structure. [Ken Coar]
1436 *) Fix a segfault in mod_rewrite's logging code caused by passing the
1437 wrong config to ap_get_remote_host(). [Jeff Trawick]
1439 *) Allow mod_cgid to work from a binary distribution install by
1440 using 755 for the permissions on the log directory instead of
1443 *) Fixed a segfault that happened during graceful shutdown (or when
1444 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
1446 *) Split all Win32 modules [excluding the core components mod_core,
1447 mod_so, mod_win32 and the winnt mpm] into individual loadable
1448 modules, so the administrator may individually disable the former
1449 compiled-in modules by simply commenting out their LoadModule
1450 directives. [William Rowe]
1452 *) Saved Win32 module authors and porters many future headaches, by
1453 duplicating the appropriate .h files such as os.h into the include
1454 directory, including in the build tree. [William Rowe]
1456 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
1457 Use SSL functions/macros instead of directly dereferencing SSL
1458 structures wherever possible.
1459 Add type-casts for the cases where functions return a generic pointer.
1460 Add $SSL/include to configure search path.
1461 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1463 *) Moved several pointers out of the shared Scoreboard so it is
1464 more portable, and will present the vhost name across server
1465 generation restarts. [William Rowe]
1467 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
1470 Changes with Apache 2.0.30
1472 *) Fix the main bug for FreeBSD and threaded MPM's. There are
1473 still issues (see STATUS) but at least the server will now
1474 run without crashing the machine.
1475 [David Reid, Aaron Bannert, Justin Erenkrantz]
1477 *) Fix a typo in mod_deflate's m4 config section.
1478 [albert chin (china@thewrittenword.com)]
1480 *) Fix a couple of mod_proxy problems forwarding HTTP connections
1481 and handling CONNECT:
1482 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
1483 (2) Proxy failed to connect when the first IP address returned by
1484 the resolver was unreachable but a secondary IP address was.
1487 *) Fix the module identifer as shown in the docs for various core
1488 modules (e.g., the identifer for mod_log_config was previously
1489 listed as config_log_module). PR #9338
1490 [James Watson <ap2bug@sowega.org>]
1492 *) Fix LimitRequestBody directive by placing it in the HTTP
1493 filter. [Justin Erenkrantz]
1495 *) Fix mod_proxy seg fault when the proxied server returns
1496 an HTTP/0.9 response or a bogus status line.
1499 *) Prevent mod_proxy from truncating one character off the
1500 end of the status line returned from the proxied server.
1501 [Adam Sussman, Bill Stoddard]
1503 *) Eliminate loop in ap_proxy_string_read().
1504 [Adam Sussman, Bill Stoddard]
1506 *) Provide $0..$9 results from mod_include regex parsing.
1509 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
1511 *) Introduced the ForceLanguagePriority directive, to prevent
1512 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
1513 when using Multiviews. [William Rowe]
1515 *) Fix a problem which prevented mod_cgid and suexec from working
1516 together reliably [Greg Ames]
1518 *) Remove the call to exit() from within mod_auth_digest's post_config
1519 phase. [Aaron Bannert]
1521 *) Fix a problem in mod_auth_digest that could potentially cause
1522 problems with initialized static data on a system that uses DSOs.
1525 *) Fix a segfault in the worker MPM that could happen during
1526 child process exits. [Brian Pane, Aaron Bannert]
1528 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
1530 *) Fix matching of vhosts by ip address so we find IPv4
1531 vhost address when target address is v4-mapped form of
1532 that address. [Jeff Trawick]
1534 *) More performance tweaks to the BNDM string-search algorithm
1535 used to find "<!--#" tokens in mod_include [Brian Pane]
1537 *) Miscellaneous small performance fixes: optimized away various
1538 string copy operations and removed large temp buffers from
1539 the stack [Brian Pane]
1541 *) Fixed startup segfault that occurred when a VirtualHost
1542 directive had a port but no address [Brian Pane]
1544 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
1546 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
1547 if oslevel < WINNT. This should fix several problems reported
1548 Against 2.0.28 on Windows 98 [Bill Stoddard]
1550 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
1551 to fail. [Bill Stoddard]
1553 *) Change core code to allow an MPM to set hard thread/server
1554 limits at startup. prefork, worker, and perchild MPMs now have
1555 directives to set these limits. [Jeff Trawick]
1557 *) Win32: The async AcceptEx() event should be autoreset upon
1558 successful completion of a wait (WaitForSingleObject). This
1559 eliminates a number of spurious
1560 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
1563 *) Move any load library path environment variables out of
1564 apachectl and into a separate environment variable file which
1565 can be more easily tailored by the admin. The environment
1566 variable file as built by Apache may have additional system-
1567 specific settings. For example, on OS/390 we tailor the heap
1568 settings to allow lots of threads. [Jeff Trawick]
1570 *) Use the new APR pool code to reduce pool-related lock
1571 contention in the worker MPM. [Sander Striker]
1573 *) The POD no longer assumes the child is listening on 127.0.0.1
1574 and now pulls the first hostname in the list of listeners to
1575 perform the dummy connect on. This fixes a bug when the user
1576 had configured the Listen directive for an IP other than
1577 127.0.0.1. This would result in undead children and error
1578 messages such as "Connection refused: connect to listener".
1581 *) The worker MPM now respects the LockFile setting, needed to
1582 avoid locking problems with NFS. [Jeff Trawick]
1584 *) Fix segfault when worker MPM receives SIGHUP.
1585 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
1587 *) Fix bug that could potentially prevent the perchild MPM from
1588 working with more than one vhost/uid. [Aaron Bannert]
1590 *) Change make install and apxs -i processing of DSO modules to
1591 perform special handling on platforms where libtool doesn't install
1592 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
1593 which prevented standard LoadModule statements from working.
1596 *) Whenever mod_so is enabled (not just when there are DSOs for
1597 our modules), do whatever special magic is required for compiling/
1598 loading third-party modules. This allows third-party DSOs to
1599 be used on an AIX build when there were no built-in modules
1600 built as DSOs. (This should help on OS/390 and BeOS as well.)
1603 *) Allow apxs to be used to build DSOs on AIX without requiring the
1604 user to hard-code the list of import files. (This should help
1605 on OS/390 and BeOS as well.) [Jeff Trawick]
1607 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
1608 PR 8563, 8919 [William Rowe]
1610 *) Get binary builds working when libapr and libaprutil are built
1613 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
1614 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
1615 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
1617 *) Fix the handling of SSI directives in which the ">" of the
1618 terminating "-->" is the last byte in a file [Brian Pane]
1620 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
1621 message that we had back in apache-1.3 and still have scattered
1622 throughout our docs. [Aaron Bannert]
1624 *) Prevent the Win32 port from continuing after encountering an
1625 error in the command line args to apache. [William Rowe]
1627 *) On a error in the proxy, make it write a line to the error log
1630 *) Various mod_ssl performance improvements [Doug MacEachern]
1632 Changes with Apache 2.0.29
1634 *) Add buffering in core_output_filter to ensure that long
1635 lists of small buckets don't cause small packet writes.
1636 [Brian Pane, Ryan Bloom]
1638 *) Fix the installation target to make sure that the manual is
1639 installed in the correct location.
1640 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
1641 Gomez Henri <hgomez@slib.fr>]
1643 *) Fix the cmd command for mod_include. When we are processing
1644 a cmd command, we do not want to use the r->filename to set
1645 the command name. The command comes from the SSI tag. To do this,
1646 I added a variable to the function that builds the command line
1647 in mod_cgi. This allows the include_cmd function to specify
1648 the command line itself. [Ryan Bloom]
1650 *) Change open_logs hook to return a value, allowing you
1651 to flag a error while opening logs
1652 [Ian Holsman, Doug MacEachern]
1654 *) Change post_config hook to return a value, allowing you
1655 to flag a error post config
1656 [Ian Holsman, Jeff Trawick]
1658 *) Allow SUEXEC_BIN (the path to the suexec binary that is
1659 hard-coded into the server) to be specified to the configure
1660 script by the --with-suexec-bin parameter. [Aaron Bannert]
1662 *) Fix segv in worker MPM following accept on pipe-of-death
1665 *) Add mod_deflate to experimental.
1666 [Ian Holsman, Justin Erenkrantz]
1668 *) Bail out at configure time if an invalid MPM was specified.
1669 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1671 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
1672 configured [John Sterling <sterling@covalent.net>]
1674 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
1676 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
1678 *) Optimization for the BNDM string-search function in
1679 mod_include. [Brian Pane]
1681 *) Fixed the behavior of the XBitHack directive.
1682 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
1684 *) The threaded MPM for Unix has been removed. Use the worker
1685 MPM instead. [various]
1687 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
1688 in logging the error from a failed DNS lookup. [Jeff Trawick]
1690 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
1693 *) Get mod_cgid killed when a MPM exits due to a fatal error.
1696 *) Fix a file descriptor leak in mod_include. When we include a
1697 file, we use a sub-request, but we didn't destroy the sub-request
1698 immediately, instead we waited until the original request was
1699 done. This patch closes the sub-request as soon as the data is
1700 done being generated. [Brian Pane <bpane@pacbell.net>]
1702 *) Allow modules that add sockets to the ap_listeners list to
1703 define the function that should be used to accept on that
1704 socket. Each MPM can define their own function to use for
1705 the accept function with the MPM_ACCEPT_FUNC macro. This
1706 also abstracts out all of the Unix accept error handling
1707 logic, which has become out of synch across Unix MPMs.
1710 *) Fix a bug which would cause the response headers to be omitted
1711 when sending a negotiated ErrorDocument because the required
1712 filters were attached to the wrong request_rec.
1713 [John Sterling <sterling@covalent.net>]
1715 *) Remove commas from the end of the macros that define
1716 directives that are used by MPMs. Prior to this patch,
1717 you would use these macros without commas, which was unlike
1718 the macros for any other directives. Now, the caller provides
1719 the comma rather than the macro providing it. This makes
1720 the macros look more like the rest of the directives.
1721 [Ryan Bloom and Cliff Woolley]
1723 *) Add 'redirect-carefully' environment option to disable sending
1724 redirects under special circumstances. This is helpful for
1725 Microsoft's WebFolders when accessing a directory resource via
1726 DAV methods. [Justin Erenkrantz]
1728 *) Begin to abstract out the underlying transport layer.
1729 The first step is to remove the socket from the conn_rec,
1730 the server now lives in a context that is passed to the
1731 core's input and output filters. This forces us to be very
1732 careful when adding calls that use the socket directly,
1733 because the socket isn't available in most locations.
1736 *) Really reset the MaxClients value in worker and threaded
1737 when the configured value is not a multiple of the number
1738 of threads per child. We said we did previously but we
1739 forgot to. [Jeff Trawick]
1741 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
1743 *) If shared modules are requested and mod_so is not available,
1744 produce a fatal config-time error. [Justin Erenkrantz]
1746 *) Improve http2env's performance by cutting the work it has to
1747 do. [Brian Pane <bpane@pacbell.net>]
1749 *) use new 'apr_hash_merge' function in mod_mime (performance fix)

1752 Changes with Apache 2.0.28
1754 *) Fix infinite loop in mod_cgid.c.
1755 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
1757 *) When no port is given in a "ServerName host" directive, the
1758 server_rec->port is now set to zero, not 80. That allows for
1759 run-time deduction of the correct server port (depending on
1760 SSL/plain, and depending also on the current setting of
1761 UseCanonicalName). This change makes redirections
1762 work, even with https:// connections. As in Apache-1.3, the
1763 connection's actual port number is never used, only the ServerName
1764 setting or the client's Host: setting. Documentation updated
1765 to reflect the change. [Martin Kraemer]
1767 *) Add a '%{note-name}e' argument to mod-headers, which works in
1768 the same way as mod_log_confg. [Ian Holsman]
1770 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
1771 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
1772 MPMs. [Cliff Woolley]
1774 *) Introduce htdbm, a user management utility for db/dbm authorization
1775 databases. [Mladen Turk <mturk@mappingsoft.com>]
1777 *) Optimize usage of strlen and strcat in ap_directory_walk.
1778 [Brian Pane <bpane@pacbell.net>]
1780 Changes with Apache 2.0.27
1782 *) Introduce an Apache mod_ssl initial configuration template
1783 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
1785 *) Fixed a memory leak in the getline parsing code that could
1786 be triggered by arbitrarily large header lines. Requests
1787 from the core input filter for single lines are now limited
1788 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
1790 *) Fix a truncation bug in how we print the port on the Via: header.
1791 The routine that prints the Via: header now takes a length for
1792 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
1794 *) Some syntax errors in mod_mime_magic's magic file can result
1795 in a 500 error, which previously was unlogged. Now we log the
1796 error. [Jeff Trawick]
1798 *) Add the support/checkgid helper app, which checks the run-time
1799 validity of group identifiers usable in the Group directive.
1802 *) Various --enable-so options have been fixed: --enable-so is
1803 treated as "static"; explicit --enable-so=shared issues an error;
1804 and explicit --enable-so fails with error on systems without
1805 APR_HAS_DSO. [Aaron Bannert]
1807 *) Fix a segfault in the core input filter when the client socket
1808 gets disconnected unexpectedly. [Cliff Woolley]
1810 *) Fix the reporting for child processes that die. This removes
1811 all of the non-portable W* macros from Apache.
1812 [Jeff Trawick and Ryan Bloom]
1814 *) Win32: Track and display "Parent Server Generation:" in
1815 mod_status output. The generation will be bumped at
1816 server graceful restart, when the child process exits
1817 by hitting MaxRequestsPerChild or if the child
1818 process exits abnormally. [Bill Stoddard]
1820 *) Win32: Fix problem where MaxRequestsPerChild directive was
1821 not being picked up in favor of the default. Enable
1822 the parent to start up a new child process immediately upon
1823 the old child starting shutdown.
1826 *) Fix some bungling of the remote port in rfc1413.c so that
1827 IdentityCheck retrieves the proper user id instead of failing
1828 and thus always returning "nobody."
1829 [Dick Streefland <Dick.Streefland@xs4all.nl>]
1831 *) Introduced thread saftey for mod_rewrite's internal cache.
1832 [Brian Pane <bpane@pacbell.net>]
1834 *) Simplified mod_env's directives to behave as most directives are
1835 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
1836 directive following that UnsetEnv within the same container.
1837 Also provides a runtime startup warning if a PassEnv configured
1838 environment value is undefined. [William Rowe]
1840 *) The worker MPM is now completely ported to APR's new lock API. It
1841 uses native APR types for thread mutexes, cross-process mutexes,
1842 and condition variables. [Aaron Bannert]
1844 *) Sync up documentation to remove all references to the now deprecated
1845 Port directive. [Justin Erenkrantz]
1847 *) Moved all ldap modules from the core to httpd-ldap sub-project
1850 *) Exit when we can't listen on any of the configured ports. This
1851 is the same behavior as 1.3, and it avoids having the MPMs to
1852 deal with bogus ap_listen_rec structures. [Jeff Trawick]
1854 *) Cleanup the proxy code that creates a request to the origin
1855 server. This change adds an optional hook, which allows modules
1856 to gain control while the request is created if the proxy module
1857 is loaded. The purpose of this hook is to allow modules to add
1858 input and/or output filters to the request to the origin. While
1859 I was at it, I made the core use this hook, so that proxy request
1860 creation uses some of the code from the core. This can still be
1861 greatly improved, but this is a good start. [Ryan Bloom]
1863 Changes with Apache 2.0.26
1865 *) Port the MaxClients changes from the worker MPM to the threaded
1868 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
1869 with the new input filtering system. [Justin Erenkrantz]
1871 *) Introduce the MultiviewsMatch directive, to allow the operator
1872 to be flexible in recognizing Handlers and Filters filename
1873 extensions as part of the Multiviews matching logic, strict with
1874 MultiviewsMatch NegotiatedOnly to accept only filename extentions
1875 that designate negotiated parameters, (content type, charset, etc.)
1876 or MultiviewsAll for the 1.3 behavior of matching any files, even
1877 if they have unregistered extensions. [William Rowe]
1879 *) Fixed the configure script to add a LoadModule directive to
1880 the default httpd.conf for any module that was compiled
1881 as a DSO. [Aaron Bannert <aaron@clove.org>]
1883 *) rewrite mod_ssl input filtering to work with the new input filtering
1884 system. [Justin Erenkrantz]
1886 *) prefork: Don't segfault when we are able to listen on some but
1887 not all of the configured ports. [Jeff Trawick]
1889 *) Build mod_so even if no core modules are built shared.
1890 [Aaron Bannert <aaron@clove.org>]
1892 *) Introduce ap_directory_walk rewrite (with further optimizations
1893 required) to adapt to the ap_process_request_internal() changes.
1894 Optimized so subrequests and redirects now reuse previous section
1895 merges, until we mismatch with the original directory_walk, and
1896 precomputed r->finfo results will cause directory_walk to skip
1897 the most expensive phases of the function. [William Rowe]
1899 *) Allow ApacheMonitor to connect to and control Apache on other
1900 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
1902 *) Remove the Port directive. In it's place, the Listen directive
1903 is now a required directive, which tells Apache what port to
1904 listen on. The ServerName directive has also been extended
1905 to accept an optional port. If the port is specified to the
1906 ServerName, the server will report that port whenever it
1907 reports the port that it is listening on. This change was
1908 made to ease configuration errors that stem from having a Port
1909 directive, and a Listen directive. In that situation, the server
1910 would only listen to the port specified by the Listen command,
1911 which caused a lot of confusion to users. [Ryan Bloom]
1913 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
1914 build, as loadable modules. [William Rowe]
1916 *) Fix --enable-mods-shared processing. If most is specified,
1917 then all modules that can be compiled as shared modules are.
1918 [Aaron Bannert <aaron@clove.org>]
1920 *) Update the mime.types file to map video/vnd.mpegurl to mxu
1921 and add commonly used audio/x-mpegurl for m3u extensions.
1922 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
1924 *) Eliminate the depreciated r->content_language, in favor of the array
1925 r->content_languages introduced many years ago. Module authors must
1926 substantially overhaul their modules, so this needs to be upgraded
1927 if the module still relied on backwards-brokeness. [William Rowe]
1929 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
1932 *) Rewrite the input filtering mechanisms to consolidate and reorganize
1933 code. In short, core_input_filter does something now and
1934 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
1936 *) Update the Win32 build to re-absorb mod_proxy and family.
1939 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
1940 current SDK.) [William Rowe]
1942 *) Some style changes to the code that does ProxyErrorOverride. Fixed
1943 config merge behaviour. [Graham Leggett]
1945 *) Allow support programs to be compiled against a static version
1946 of libapr. This allows the smaller support programs to be
1947 relocated. [Aaron Bannert <aaron@clove.org>]
1949 *) Update the mime.types file to the registered media types as
1950 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
1952 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
1953 number of clients that can connect at the same time, instead of
1954 specifying the maximum number of child processes.
1955 [Aaron Bannert <aaron@clove.org>]
1957 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
1958 be consistent with 1.3. [Justin Erenkrantz]
1960 *) Cache apr_explode_localtime() value for 15 seconds.
1961 [Brian Pane <bpane@pacbell.net>]
1963 *) Fix mod_include to not return ETag or Last-Modified headers.
1964 [Ian Holsman <ianh@cnet.com>]
1966 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
1968 *) Eliminate the wasteful run-time conversion of method names from strings
1969 to numbers in places where the methods are known at compile time.
1970 [Brian Pane <bpane@pacbell.net>]
1972 *) Turn the worker MPM's queue into a LIFO. This may
1973 improve cache-hit performance under some conditions.
1974 [Aaron Bannert <aaron@clove.org>]
1976 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
1977 support it. [Justin Erenkrantz]
1979 *) Cleanup the worker MPM. We no longer re-use transaction
1980 pools. This incurs less overhead than shuffling the pools
1981 around so that they can be re-used. Remove one of the
1982 queue's condition variables. We just redefined the API to
1983 state that you can't try to add more stuff than you allocated
1984 segments for. [Aaron Bannert <aaron@clove.org>]
1986 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
1988 *) Fixed persistent connections when a request contains a body.
1991 *) mod_dav uses a new API to speak to the backend provider for dead
1992 property management. [Greg Stein]
1994 *) Remove the Win32 script-processing exception from mod_cgi, and
1995 roll build_command_line/build_argv_list into a unified, overrideable
1996 ap_cgi_build_command optional function. [William Rowe]
1998 *) Rewrite find_start_sequence to use a better search algorithm
1999 to find the start tag. [Justin Erenkrantz]
2001 *) Fix a seg fault in mod_include. When we are generating an
2002 internal redirect, we must set r->uri to "", not a bogus
2003 string, and not NULL. [Ryan Bloom]
2005 *) Optimized location_walk, so subrequests, redirects and second passes
2006 now reuse previous section merges on a <Location > by <Location >
2007 basis, until we mismatch with the original location_walk.
2010 *) Back out the 1.45 change to util_script.c. This change made
2011 us set the environment variable REQUEST_URI to the redirected
2012 URI, instead of the originally requested URI.
2013 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2015 *) Make mod_include do lazy evaluation of potentially expensive to
2016 compute variables. [Brian Pane <bpane@pacbell.net>]
2018 *) Fix logging of bytes sent for HEAD requests. %b and %B should
2019 log either - or 0, before this patch, they were both logging
2020 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2022 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
2023 than per character. [Brian Pane <bpane@pacbell.net>]
2025 *) Normalize the primary request, redirects and sub-requests to
2026 run the same ap_process_request_internal for consistency in
2027 robustness, behavior and security. [William Rowe]
2029 *) Fix a segfault with mod_include when r->path_info is not set
2030 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
2032 *) Add -X functionality back. This indicates to all MPMs and any other
2033 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
2035 *) Some initial support for the cygwin platform [prefork only].
2036 This is not to be confused with support for the WinNT/Win32
2037 platform, which is the recommended configuration for native
2038 Win32 users. The cygwin platform support is recommended for
2039 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
2041 *) Changed syntax of Set{Input|Output}Filter. The list of filters
2042 must be semicolon delimited (if more than one filter is given.)
2043 The Set{Input|Output}Filter directive now overrides a parent
2044 container's directive (e.g. SetInputFilter in <Directory /web/foo>
2045 will override any SetInputFilter directive in <Directory /web>.)
2046 This new syntax is more consistent with Add{Input|Output}Filter
2047 directives defined in mod_mime. Also cures a bug in prior releases
2048 where the Set{Input|Output}Filter directive would corrupt the
2049 global configuration if the multiple directives were nested.
2052 *) Cured what's ailed mime for quite some time. If an AddSomething
2053 was given in the configuration (Language, Charset, Handler or
2054 Encoding) Apache would set the content type as given by AddType,
2055 but refused to check the mime.types file if AddType wasn't given
2056 for that specific extension. Setting the AddHandler for .html
2057 without setting the AddType text/html html would cause Apache to
2058 use the default content type. [William Rowe]
2060 *) Added some bulletproofing to memory allocation in the LDAP cache
2061 code. [Graham Leggett]
2063 Changes with Apache 2.0.25
2065 *) Move the installed /manual directory out of the /htdocs/ tree, so
2066 that it can be kept more independently from the remaining document
2067 root. The "Alias /manual ..." already allowed for easy projection
2068 into existing private document trees. [Martin Kraemer]
2070 *) Add specified user attributes to the environment when using
2071 mod_auth_ldap. This allows you to use mod_include to embed specified
2072 user attributes in a page like so:
2073 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
2076 *) Fix a performance problem with the worker MPM. We now create
2077 transaction pools once, and re-use them for each connection.
2078 [Aaron Bannert <aaron@clove.org>]
2080 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
2081 of a 'handler' or 'filter', so that any filename extension that does
2082 not contribute to the negotiated metadata can't be served without
2083 an explicit request. E.g., if the .Z extension is associated with
2084 an unzip filter, the user request somefile.Z.html, mod_negotiation
2085 won't serve it. It can serve somefile.Z.html when somefile.Z is
2086 requested, since the .Z extension is explictly requested, if the
2087 .html extension is associated with ContentType text/html.
2090 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
2091 and corresponding AddOutputFilter syntax, to insert one or more
2092 filters by mod_mime filename extension processing.
2095 *) Fix a growing connection pool in core_output_filter() for
2096 keepalive requests. [Jeff Trawick]
2098 *) Moved split_and_pass_pretag_buckets back to being a
2099 macro at Ryans's request. Removed the return from it
2100 by setting and returning a return code instead. Updated
2101 the code to check the return code from the macro and
2102 do the right thing. [Paul J. Reder]
2104 *) Fix a segfault when a numeric value was received for Host:.
2107 *) Add a function ap_remove_input_filter. This is to match
2108 up with ap_remove_output_filter. [Ryan Bloom]
2110 *) Clean up location_walk, so that this step performs a minimum
2111 amount of redundant effort (it must be run twice, but it will no
2112 longer reparse all <Location > blocks when the request uri
2113 hadn't changed.) [William Rowe]
2115 *) Eliminate proxy: (and all other 'special') processing from the
2116 ap_directory_walk() phase. Modules that want to use special
2117 walk logic should refer to the mod_proxy map_to_location example,
2118 with it's proxy_walk and proxysection implementation. This makes
2119 either directory_walk flavor much more legible, since that phase
2120 only runs against real <Directory > blocks.
2123 *) SECURITY: Fix a security problem in mod_include which would allow
2124 an SSI document to be passed to the client unparsed.
2125 [Cliff Woolley, Brian Pane]
2127 *) Introduce the map_to_storage hook, which allows modules to bypass
2128 the directory_walk and file_walk for non-file requests. TRACE
2129 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
2130 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
2133 *) Add the ability for mod_include to add the INCLUDES filter
2134 if the file is configured for the server-parsed handler.
2135 This makes the configuration for .shtml files much easier
2136 to understand, and allows mod_include to honor Apache 1.3
2137 config files. Based on Doug MacEachern's patch to PHP
2138 to do the same thing. [Ryan Bloom]
2140 *) force OpenSSL to ignore process local-caching and to always
2141 get/set/delete sessions using mod_ssl's callbacks
2142 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
2143 Geoff Thorpe <geoff@geoffthorpe.net>]
2145 *) Make the worker MPM shutdown and restart cleanly. This also
2146 cleans up some race conditions, and gets the worker using
2147 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
2149 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
2151 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2153 *) Fix for mod_include. Ryan's patch to check error
2154 codes put a return in the wrong place. Also, the
2155 include handler return code wasn't being checked.
2156 I don't like macros with returns, so I converted
2157 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
2158 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2160 *) fix segv in mod_mime if no AddTypes are configured
2161 [John Sterling <sterling@covalent.net>]
2163 *) Enable ssl client authentication at SSL_accept time
2164 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2166 *) Fix a segfault in mod_include when the original request has no
2167 associated filename (e.g., we're filtering the error document for
2168 a bad URI). [Jeff Trawick]
2170 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
2172 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
2173 of httpd is started and shuts down due to socket conflict. Moving the
2174 call to ap_log_pid solves the problem.
2176 *) Changed the late-1.3 log_config substitution %c to %X, to log the
2177 status of the closed connection, as it conflicts with the far more
2178 common, historical ssl logging directive %...{var}c. [William Rowe]
2180 *) Added the common error/ tree to the build/install targets
2181 (similar to the common icons/ tree) for the multi-language error
2182 messages that Lars committed earlier. [William Rowe]
2184 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
2186 *) Added a default commented-out mod_ldap and mod_auth_ldap
2187 configuration to httpd-std.conf and httpd-win.conf
2190 *) Added documentation for mod_ldap and mod_auth_ldap.
2193 *) Enabled negative caching on attribute comparisons in the LDAP cache.
2194 Fixed a problem where the default cache TTL was set in milliseconds
2195 not microseconds causing the cache to time out almost immediately.
2198 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
2199 module code to follow APR. [Graham Leggett]
2201 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
2202 cleaned up when the connection pool pool is cleaned up.
2205 *) Fix a minor issue with Jeff Trawick's mod_include
2206 patch. Without this patch, the code will just allocate
2207 more bytes in get_combined_directive than are needed.
2210 *) Added the LDAP authentication module mod_auth_ldap.
2211 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
2213 *) Added the LDAP cache and connection pooling module mod_ldap.
2214 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
2216 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
2217 by allowing a module to disable itself if its prerequisites are not
2218 met. [Justin Erenkrantz]
2220 Changes with Apache 2.0.24
2222 *) Fix a couple of issues in mod_include when the tag appeared at
2223 offsets near 8192 in the file being parsed. [Jeff Trawick]
2225 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
2226 reached. [Jeff Trawick]
2228 *) Numerous improvements to the Win32 build system. Introduced command line
2229 builds without requiring .mak files for MSVC 6.0 and later versions.
2230 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
2233 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
2234 reporting of uninstalled services and other error conditions, and changed the
2235 default service name to Apache2. [William Rowe]
2237 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
2238 compatibility with existing Apache 1.3 Win32 Apache management utilites.
2239 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
2241 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
2242 [William Rowe, Greg Ames]
2244 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
2245 and RemoveCharset directives. [William Rowe]
2247 *) The Unix MPMs other than perchild now allow child server
2248 processes to use the accept mutex when starting as root and
2249 using SysV sems for the accept mutex. Previously, this
2250 combination would lead to fatal errors in the child server
2251 processes. perchild can't use SysV sems because of security
2252 issues. [Jeff Trawick, Greg Ames]
2254 *) Added Win32 revision stamp resources to all http binaries
2255 (including modules/ and support/ tools.) PR7322 [William Rowe]
2257 *) Fix ap_rvprintf to support more than 4K of data at one time.
2258 [Cody Sherr <csherr@covalent.net>]
2260 *) We have always used the obsolete/deprecated Netscape syntax
2261 for our tracking cookies; now the CookieStyle directive
2262 allows the Webmaster to choose the Netscape, RFC2109, or
2263 RFC2965 format. The new CookieDomain directive allows the
2264 setting of the cookie's Domain= attribute, too. PR #s 5006,
2265 5023, 5920, 6140 [Ken Coar]
2267 *) Tweak server/Makefile so that the rules for generating exports.c
2268 are compatible with make utilities which don't expand wildcards
2269 in a dependency list (e.g., OS/390 make, certain levels of GNU
2270 make). [Jeff Trawick]
2272 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
2274 *) Begin to sanitize the MPM configuration directives. Now, all
2275 MPMs use the same functions for all common MPM directives. This
2276 should make it easier to catch all bugs in these directives once.
2277 [Cody Sherr <csherr@covalent.net>]
2279 *) Close a major resource leak. Every time we had issued a
2280 graceful restart, we leaked a socket descriptor.
2283 *) Fix a problem with the new method code. We need to cast
2284 the 1 to an apr_int64_t or it will be treated as a 32-bit
2285 integer, and it will wrap after being shifted 32 times.
2286 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
2288 *) Fix a bug in mod_expires. Previous to this patch, if you
2289 told mod_expires to add 604800 seconds to the last-modified
2290 time, it actually added 604800 usec's to the last-modified time,
2291 so that when looking at the response it looked like nothing
2292 had been done. The root of the problem was that we always compute
2293 time in usec's, but we ask users to input sec's. This means we
2294 need to convert to usec's before using those values.
2297 *) The worker MPM now handles shutdown and restart requests. It
2298 definitely isn't perfect, but we do stop the servers correctly.
2299 The biggest problem right now is that SIGHUP causes the server to
2300 just die. [Ryan Bloom]
2302 Changes with Apache 2.0.23
2304 *) Use the prefork MPM by default on Unix. [various]
2306 *) Added a systray icon monitor application for Win32.
2307 [Mladen Turk <mturk@mappingsoft.com>]
2309 *) mod_rewrite: Fix the line ending on some non-Unix systems for
2310 messages written to the rewrite log.
2311 [Richard Labennett <rlabenn@us.ibm.com>]
2313 *) All mod_autoindex query parsing is now quietly quashed with the
2314 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
2315 still drops the column sort <a href>'s for the column headers, but
2316 IgnoreClient is required to ignore these Query options entirely.
2319 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
2320 to allow the client to select plain, FancyIndexing or HTMLTable
2321 formatting, V=[0|1] to inhibit or enable version sorting, and
2322 P=pattern to return only specific files. The old Query Arguments
2323 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
2324 as before), and O=A|D for ordering ascending or descending.
2327 *) Fixed an error in mod_include's directive parsing routines which
2328 caused #if, #elif, and #else expressions containing backslashes
2329 to be improperly evaluated. [Cliff Woolley]
2331 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
2332 drop the icon column, SuppressRules to drop the <hr> elements,
2333 and HTMLTable to create rudimentary HTML table listings (implies
2334 FancyIndexing). [William Rowe]
2336 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
2337 from Apache 1.3.15. This is needed for two reasons, first, given
2338 multiple machines within a server farm, ETags and Last-Modified
2339 stamps won't correspond from machine to machine, and second, many
2340 Unixes don't capture changes to the date or time stamp of existing
2341 files, since these don't modify the dirent itself. [William Rowe]
2343 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
2344 and DirectoryWidth options from Apache 1.3.10.
2345 [William Rowe, Ken Coar]
2347 *) Eliminated FancyIndexing directive, deprecated early in Apache
2348 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
2350 *) mod_autoindex now excludes any file names that would result in
2351 an error, other than a success or redirect. Also optimized
2352 the parent directory, always included except in the URI '/'.
2355 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
2356 negotiated index pages, and prevent the server from defaulting
2357 to an autoindex of the directory. mod_negotiation will now die
2358 with a 500 Internal Error if it could match some filenames
2359 (e.g. for mod_dir) but none can be served. mod_negotation now
2360 refuses to serve any file with an extention that mod_mime doesn't
2361 recognize, and wasn't part of the request. [William Rowe]
2363 *) Eliminate mod_cgi's handling of .exe files without the .exe file
2364 extension. This is already handled by multiviews, if the admin
2365 wishes to AddHandler .exe or define a content type handler and
2366 associate .exe files with that content type. Multiviews must be
2367 enabled to allow these to be served. [William Rowe]
2369 *) Speed up the server's response to a spike in incoming workload
2370 or restarts by assigning empty scoreboard slots to new processes
2371 when they are available. [Greg Ames]
2373 *) Add a handler to mod_includes.c. This handler is designed to
2374 implement the XbitHack directive. This can't be done with a
2375 fixup, because we need to check the content-type, which is
2376 only available in the handler phase. [Ryan Bloom]
2378 *) Make the includes filter check return codes from filters lower in
2379 the filter chain. If a lower level filter returns an error, then
2380 the request needs to stop immediately. This allows mod_include to
2381 stop parsing data once a lower filter recognizes an error.
2384 *) Add the ability to extend the methods that Apache understands
2385 and have those methods <limit>able in the httpd.conf. It uses
2386 the same bit mask/shifted offset as the original HTTP methods
2387 such as M_GET or M_POST, but expands the total bits from an int to
2388 an ap_int64_t to handle more bits for new request methods than
2389 an int provides. [Cody Sherr <csherr@covalent.net>]
2391 *) Fix broken mod_mime behavior in merging its arguments. Possible
2392 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
2394 *) Solve many mod_ssl porting issues (too many to detail) with
2395 help from the whole team, but most notably [Ralf S. Engelschall,
2396 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
2397 Doug MacEachern, William Rowe, Cliff Woolley]
2399 *) More stall fixes for the threaded & worker mpm's.
2400 Make mod_status output more accurate. Don't
2401 count workers in processes which aren't actively
2402 serving requests. [Greg Ames]
2404 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
2406 *) Add a single listener/multiple worker MPM. This MPM is
2407 definately not fully correct, but it allows us to solve many
2408 of the problems that exist in the threaded MPM. This is a
2409 modified version of the threaded MPM. [Ryan Bloom]
2411 *) Improve content generation throughout Apache, providing closer
2412 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
2413 Transitional specifications. [William Rowe]
2415 Changes with Apache 2.0.22
2417 *) Fix a problem where the threaded MPM stalls after restarts or
2418 segfaults. Also prevent multiple active processes from using
2419 the same scoreboard slot. [Greg Ames]
2421 *) Apache/Win32 now fills in the service description with Apache's
2422 server version string, including loaded and advertised modules.
2425 *) Improved support for the Win32 build, to recover gracefully from
2426 missing apr or apr-util directories or the awk interpreter,
2427 create the proper cgi-bin examples, including a test-cgi.bat, and
2428 fix the perl shebang line for printenv.pl, when installing from
2429 the build environment. [William Rowe]
2431 *) Fix a segfault in threaded.c caused by passing uninitialized
2432 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
2434 *) Use new APR number conversion functions to reduce CPU consumption
2435 when setting the content length, and in mod_log_config.
2438 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
2439 where HEAD response headers were being repeated twice for
2440 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
2441 problem in the http_header filter was exposed by the recent rewrite
2442 of the content_length filter. [Taketo Kabe, Bill Stoddard]
2444 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
2445 restarts. A garbage pointer to a vhost's server_rec from the
2446 previous generation was being left around under certain
2447 conditions. [Greg Ames]
2449 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
2450 used to appear as '(none', without the closing paren.
2451 [Günter Knauf <eflash@gmx.net>]
2453 *) Improve the exports generating awk script. In the past, we had
2454 work around problems in the awk script by avoiding some #if and
2455 #ifdefs. This has bitten us many times in generating the exports.c
2456 file. This improvement allows corrects the header file parsing.
2457 [Sander Striker <striker@apache.org>]
2459 Changes with Apache 2.0.21
2461 *) Resolve the Win32 htpasswd bug, where a file that existed would be
2462 overwritten, regardless of the -c flag.
2463 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
2465 *) Introduce connection sub-pools into ab. Truncating the lifetime
2466 of these allocations means that ab no longer perpetually grows
2467 its working set, running out of memory on large request attempts.
2470 *) Make scoreboard creation a hook. This allows management
2471 modules to have access to the scoreboard at the time that it is
2472 created, and at every restart request.
2473 [Cody Sherr <csherr@covalent.net>]
2475 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
2476 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
2477 daemon index actually used in the scoreboard. I also
2478 updated the pertinent calls. [Paul J. Reder]
2480 *) Win32: Prevent listening sockets from being inherited by
2481 the Apache child process, CGI scripts, rotatelog process
2482 etc. If the Apache child process segfaults, any processes
2483 that the child started are not reaped. Prior to this fix,
2484 these processes inherited the listening sockets which sometimes
2485 prevented the restarted Apache child process from accepting
2486 connections (ie, the server would hang).
2489 *) Provide vhost and request strings when ExtendedStatus is on.
2492 *) Fix some issues with the pod and prefork: check the pod *after*
2493 processing a connection so that a server processing a time-
2494 consuming request bails out as soon as practical; when the
2495 parent process wakes up a server process via connect(), use an
2496 APR timeout on the connect() so that we don't hang for a long
2497 time if there aren't server processes around to do accept().
2498 [Jeff Trawick, Greg Ames]
2500 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
2501 spends a lot of time in apr_table_get calls. Using the default
2502 httpd.conf, the tables for languages and charsets are somewhat
2503 large, so the time spent scanning them on each request is
2504 significant. Replacing the tables with hash tables provides
2505 a nice speedup. [Brian Pane <bpane@pacbell.net>]
2507 *) Add two functions to allow modules to access random parts of the
2508 scoreboard. This allows modules compiled for one MPM to access the
2509 scoreboard, even if it the server was compiled for another MPM.
2510 [Harrie Hazewinkel <harrie@covalent.net>]
2512 Changes with Apache 2.0.20
2514 *) Fix problem in content-length filter where the filter would
2515 buffer all the output from a CGI before sending any bytes
2516 down the filter stack to the network. This problem would cause
2517 significant memory consumption if the CGIs generated
2518 lots of bytes. [Bill Stoddard]
2520 *) Get non-blocking CGI pipe reads working with the bucket brigades.
2523 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
2526 *) Fix a bug in the threaded MPM that would cause it to kill off all
2527 workers immediately after starting if the number of workers started
2528 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
2530 Changes with Apache 2.0.19
2532 *) Fix problem with threaded MPM. The problem was that if each child
2533 process was busy serving a single long-lived request and the server
2534 was sent a graceful restart signal, the server would stop serving
2535 requests. This would happen because each child process would wait to
2536 die until the last thread was done, and the parent wouldn't spawn any
2537 new children until a process died. Now, the parent looks at the fact
2538 that the children are dying gracefully, and starts new children.
2539 Those new children only start enough threads to compliment the number
2540 of threads in the other child process that shares the same spot in
2541 the scoreboard. In this way, we make sure to never go over
2542 MaxClients. [Ryan Bloom]
2544 *) modified mod_negotiation and mod_autoindex to speed up by almost a
2545 factor of two on apr_dir_read()-enhanced platforms, such as Win32
2546 and OS2, by calling ap_sub_request_lookup_dirent() with the results
2547 already provided by apr_dir_read(). [William Rowe]
2549 *) mod_file_cache is now more robust to filtering and serves requests
2550 slightly more efficiently. [Cliff Woolley]
2552 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
2553 Module was calling ap_rwrite() followed by ap_rflush() but the
2554 served content was not being displayed in the browser. Inspection
2555 of the output stream revealed that the first data chunk was
2556 missing the trailing CRLF required by the RFC. [Bill Stoddard]
2558 *) apxs no longer generates ap_send_http_header() in the example handler
2560 *) Fix an ab problem which could cause a divide-by-zero exception
2561 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
2562 [Ian Holsman <ianh@cnet.com>]
2564 *) Solve case-insensitive platforms' confusion about negotiated
2565 filenames, allowing files of differnt case to match in choosing
2566 the document to serve. [William Rowe]
2568 *) Fix brokenness when ThreadsPerChild is higher than the built-in
2569 limit. We left ap_threads_per_child at the higher value which
2570 led to segfaults when doing certain scoreboard operations.
2573 *) Fix seg faults and/or missing output from mod_include. The
2574 default_handler was using the subrequest pool for files and
2575 MMAPs, even though the associated APR structures typically
2576 live longer than the subrequest. [Greg Ames]
2578 *) Extend mod_setenvif to support specifying regular expressions
2579 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
2580 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
2581 will cause HAVE_TS to be set if any of the request headers begins
2582 with "TS" and has a value that begins with any character in the
2583 set [a-z]. [Bill Stoddard]
2585 *) httpd children now re-bind themselves to a random CPU on
2586 multiprocessor systems on AIX via bindprocessor() in 2.0.
2587 [Victor J. Orlikowski]
2589 *) Fix htdigest. It would go into a loop in getline when adding
2590 a second user. [Bill Stoddard]
2592 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
2594 *) Automatically generate httpd.exp for AIX.
2595 DSOs now work again on AIX in 2.0
2596 [Victor J. Orlikowski]
2598 *) Add a new request hook, error_log. This phase allows modules
2599 to act on the error log string _after_ it has been written
2600 to the error log. The goal for this hook is to allow monitoring
2601 modules to send the error string to the monitoring agent.
2604 *) Modify mod_echo to make it use filters for input and output.
2605 [Ryan Morgan <rmorgan@covalent.net>]
2607 *) Extend mod_headers to support conditional driven Header
2608 add, append and set. Use SetEnvIf to set an envar and conditionally
2609 add/append/set headers based on this envar thusly:
2611 SetEnvIf TSMyHeader value HAVE_TSMyHeader
2612 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
2614 If the request contains header "TSMyHeader: value" then header
2615 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
2618 *) Extend mod_headers to support using format specifiers on Header
2619 add, append and set header values. Two format specifiers are supported:
2621 %t - reports, in UTC microseconds since the epoch, when the
2622 request was received.
2624 %D - reports the time, in microseconds, between when the request was
2625 received and the response sent.
2628 Header add MyHeader "This request served in %D microseconds. %t"
2630 results in a header being added to the response that looks like this:
2632 MyHeader: This request served in D=5438 microseconds. t=991424704447256
2636 *) Fix reset_filter(). We need to be careful how we remove filters.
2637 If we set r->output_filters to NULL, we also have to reset the
2638 connection's filters. [John Sterling]
2640 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
2642 *) Add a check to ap_die() to make sure the filter stack is sane and
2643 contains the correct basic filters when an error occurs. This fixes
2644 a problem where headers are not being sent on error. [John Sterling]
2646 *) New Header directive 'echo' option. "Header echo regex" will
2647 cause any headers received on the request that match regex to be
2648 echoed to (included in) the response headers.
2651 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
2652 This prevented the inclusion of apr_compat.h. PR #7773
2653 [Oleg Broytmann <phd@phd.pp.ru>]
2655 *) Moved util_uri to the apr-util library. This required a bunch of
2656 apr_name changes for the uri utility functions. [Justin Erenkrantz]
2658 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
2659 insert_filter phase so that other filters are not bypassed by default.
2662 *) Reimplement mod_headers as an output filter. mod_headers can now
2663 add custom headers to inbound requests using the RequestHeader directive
2664 and to responses using the same old Header directive. [Graham Leggett]
2666 Changes with Apache 2.0.18
2668 *) Fix command-line processing so that if a bad argument is specified
2669 Apache will exit. [Jeff Trawick]
2671 *) Change the make targets and rules to be consistent in all of the
2672 Apache-owned source trees. [Roy Fielding]
2674 *) Fix processing of the TRACE method. Previously we passed bogus
2675 parms to form_header_field() and it overlaid some vhost structures,
2676 resulting in a segfault in check_hostalias().
2677 [Greg Ames, Jeff Trawick]
2679 *) Win32: Add support for reliable piped logs. If the logging process
2680 goes down, Apache will automatically restart it. This function has
2681 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
2684 *) Do not start piped log processes during the config file
2685 preflight. This change also circumvents a problem on
2686 Windows where the rotatelog processes created during preflight
2687 was not getting cleaned up properly.
2690 *) add "Request Phase Participation" info to mod_info
2693 *) Make first phase changes to the scoreboard data structures in
2694 preparation for the rewriting of the scoreboard per my posted
2695 design notes. [Paul J. Reder]
2697 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
2698 and apr-util, allow it to be overridden by the configure command-line
2699 (default="--silent") and introduce LT_LDFLAGS to replace what we were
2700 formerly abusing as LTFLAGS. [Roy Fielding]
2702 *) Clean up the reporting of incorrect closing container tags.
2703 [Barrie Slaymaker <barries@slaysys.com>]
2705 *) Simplify the configure process by moving all libtool stuff to APR
2706 and moving hints.m4 inline. [Roy Fielding]
2708 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
2709 of functions used by mod_proxy for export in the DLL
2710 [Ian Holsman <IanH@cnet.com>]
2712 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
2713 request body from its stdin but no reqest body is being written to
2714 the cgi. [Jeff Trawick]
2716 *) mod_log_config: %c connection status incorrectly logged
2717 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
2720 *) Get mod_cern_meta working under Windows
2723 *) Create Files, and thus MMAPs, out of the request pool, not the
2724 connection pool. This solves a small resource leak that had us
2725 not closing files until a connection was closed. In order to do
2726 this, at the end of the core_output_filter, we loop through the
2727 brigade and convert any data we have into a single HEAP bucket
2728 that we know will survive clearing the request_rec.
2729 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
2732 *) Completely revamp configure so that it preserves the standard make
2733 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
2734 the configure additions to EXTRA_* variables. Also, allow the user
2735 to specify NOTEST_* values for all of the above, which eliminates the
2736 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
2737 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
2738 avoid pointless duplications. Fix the order in which flags are given
2739 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
2740 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
2741 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
2742 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
2744 *) Get mod_tls to compile/work better on Windows. PR #7612
2745 [Bernhard Schrenk <b.schrenk@improx.com>]
2747 *) Fix shutdown/restart hangs in the threaded MPM.
2748 [Jeff Trawick, Greg Ames, Ryan Bloom]
2750 *) Removed the keptalive boolean from conn_rec because it is now only
2751 used by a single routine and can be replaced by a local variable.
2752 [Greg Stein, Ryan Bloom, Roy Fielding]
2754 *) Patch prefork to put enough of the signal processing back in so that
2755 signals are all handled properly now. The previous patch fixed the
2756 deadlock race condition, but broke the user directed signal handling.
2757 This fixes it to work the way it did before my previous prefork patch
2758 (primarily, SIGTERM is now working).
2760 *) Change how input filters decide how much data is returned to the
2761 higher filter. We used to use a field in the conn_rec, with this
2762 change, we use an argument to ap_get_brigade to determine how much
2763 data is retrieved. [Ryan Bloom]
2765 *) Fix seg fault at start-up introduced by Ryan's change to enable
2766 modules to specify their own logging tags. mod_log_config
2767 registers an optional function, ap_register_log_handler().
2768 ap_register_log_handler() was being called by http_core before
2769 the directive hash table was created. This patch creates the
2770 directive hash table before ap_register_log_handler() is
2771 registered as an optional function.
2772 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2774 *) Add ap_set_int_slot() function
2775 [John K. Sterling <sterling@covalent.net>]
2777 *) Under certain circumstances, Apache did not supply the
2778 right response headers when requiring authentication.
2779 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
2780 (This is a port of the change that went into Apache 1.3.19.)
2782 *) Allow modules to specify their own logging tags. This basically
2783 allows a module to tell mod_log_config that when %x is encountered
2784 a specific function should be called. Currently, x can be any single
2785 character. It may be more useful to make this a string at some point.
2788 Changes with Apache 2.0.17
2790 *) If a higher-level filter handles the the byterange aspects of a
2791 request, then the byterange filter should not try to redo the
2792 work. The most common case of this happening, is a byterange
2793 request going through the proxy, and the origin server handles
2794 the byterange request. The proxy should ignore it.
2795 [Graham Leggett <minfrin@sharp.fm>]
2797 *) Changed the threaded mpm to have child_main join to each of the
2798 worker threads to make sure the kids are all gone before child_main
2799 exits after a signal (cleanup from perform_idle_server_maintenance).
2800 This is an extension of Ryans recent commit to make the child_main
2803 *) Add more options to the ap_mpm_query function. This also allows MPMs to
2804 report if their threads are dynamic or static. Finally, this also
2805 implements a new API, ap_show_mpm, which returns the MPM that was
2806 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
2808 *) Do not install the binaries from the support directory twice.
2809 [jun-ichiro hagino <itojun@iijlab.net>]
2811 *) The ap_f* functions should flush data to the filter that is passed
2812 in, not the the filter after the one passed in.
2813 [Ryan Morgan <rmorgan@covalent.net>]
2815 *) Make ab work again by changing its native types to apr types and formats.
2816 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
2818 *) Move the byterange filter and all of the supporting functions back
2819 to the HTTP module. The byterange filter turned out to be very
2820 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
2822 *) Make clean, distclean, and extraclean consistently according to the
2823 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
2825 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
2826 This may have been causing problems stopping processes in the threaded
2829 *) Fix content-length in mod_negotiation to a long int representation.
2832 *) Remove BindAddress from the default config file.
2833 [giles@nemeton.com.au]
2835 *) Allow module authors to add a module to their Apache build using
2836 --with-module, without re-running buildconf. The syntax is:
2837 --with-module=module_type:/path/to/module.c
2838 The configure script will copy the module.c file to
2839 modules/module_type, and it will be added to the relevant Makefiles.
2840 currently, this only works for static modules. [Ryan Bloom]
2842 *) Changes required to make prefork clean up idle children properly.
2843 There was a window during which a starting worker deadlocks when
2844 an idle cleanup arrives before it completes init. Apache then keeps
2845 trying to cleanup the same deadlocked worker forever (until higher
2846 pids come along, but it still will never reduce below the deadlocked
2847 pid). Thus the number of children would not reduce to the correct
2848 idle level. [Paul J. Reder]
2850 Changes with Apache 2.0.16
2852 *) Change the default installation directory to /usr/local/apache2,
2853 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
2855 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
2858 *) Get MaxRequestsPerChild working with the Windows MPM.
2861 *) Make generic hooks to work, with mod_generic_hook_import/export
2862 experimental modules. [Ben Laurie, Will Rowe]
2864 *) Fix segfaults for configuration file syntax errors such as
2865 "<Directory>" followed by "</Directory" and
2866 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
2868 *) Cleanup the --enable-layout option of configure. This makes
2869 us use a consistent location for the config.layout file, and it
2870 makes configure more portable.
2871 [jun-ichiro hagino <itojun@iijlab.net>]
2873 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
2874 csv/gnuplot format, rudimentary ssl support and various other tweaks
2875 to make results more true to what is measured. The upshot of this it
2876 turns out that 'ab' has often underreported the true performance of
2877 apache. Often by a order of magnitude :-) See talk/paper of Sander
2878 Temme at April ApacheCon 2001 for details.
2879 [Dirk-Willem van Gulik]
2881 *) Clean up mod_cgid's temporary request pool. Besides fixing a
2882 storage leak this ensures that some unnecessary pipes are closed.
2885 *) Performance: Add quick_handler hook. This hook is called at the
2886 very beginning of the request processing before location_walk,
2887 translate_name, etc. This hook is useful for URI keyed content
2888 caches like Mike Abbott's Quick Shortcut Cache.
2891 *) top_module global variable renamed to ap_top_module [Perl]
2893 *) Move ap_set_last_modified to the core. This is a potentially
2894 controversial change, because this is kind of HTTP specific. However
2895 many protocols should be able to take advantage of this kind of
2896 information. I expect that headers will need one more layer of
2897 indirection for multi-protocol work, but this is a small step in
2898 the right direction. [Ryan Bloom]
2900 *) Enable mod_status by default. This matches what Apache 1.3 does.
2903 *) Add a ScriptSock directive to the default config file. This is
2904 only enabled when mod_cgid is used.
2905 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2907 Changes with Apache 2.0.15
2909 *) Untangled the buildconf script and eliminated the need for build's
2910 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
2911 libtool muck that is now under srclib/apr/build. [Roy Fielding]
2913 *) Win32: Don't accept more connections than we have worker threads
2917 *) Fix bug in the Unix threaded.c MPM that allowed child processes
2918 to fork() new child processes.
2921 *) SECURITY: Fix a major security problem with double-reverse lookup
2922 checking. Previously, a client connecting over IPv4 would not be
2923 matched properly when the server had an IPv6 listening socket.
2924 PR #7407 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
2926 *) Change the way the beos MPM handles polling to allow it to stop and
2927 restart. Problem was the sockets being polled were being reset by
2928 the select call, so once it had accepted a connection it was no
2929 longer listening on the UDP socket we use for shutdown instructions.
2930 APR needs to be altered, patch on it's way. [David Reid]
2932 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
2933 on error exit from ap_getline(). Some other code got upset because
2934 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
2936 *) Handle ap_discard_request_body() being called more than once.
2937 [Greg Ames, Jeff Trawick]
2939 *) Get rid of an inadvertent close of file descriptor 2 in
2940 mod_mime_magic. [Greg Ames, Jeff Trawick]
2942 *) Add a hook, create_request. This hook allows modules to modify
2943 a request while it is being created. This hook is called for all
2944 request_rec's, main request, sub request, and internal redirect.
2945 When this hook is called, the the r->main, r->prev, r->next
2946 pointers have been set, so modules can determine what kind of
2947 request this is. [Ryan Bloom]
2949 *) Cleanup the build process a bit more. The Apache configure
2950 script no longer creates its own helper scripts, it just
2952 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2954 *) Stop the forced downgrade of the connection to HTTP/1.0 for
2955 proxy requests. [Graham Leggett]
2957 *) Avoid using sscanf to determine the HTTP protocol number in
2958 the common case because sscanf is a performance hog. From
2959 Mike Abbot's Accelerating Apache patch number 6.
2960 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
2962 *) SECURITY: Fix a security exposure in mod_access. Previously when
2963 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
2964 were not evaluated properly (PR #7407). Also, add the ability to
2965 specify IPv6 address strings with optional prefix length on Allow
2966 and Deny. [Jeff Trawick]
2968 *) Enhance rotatelogs so that a UTC offset can be specified, and
2969 the logfile name can be formatted using strftime(3). (Brought
2970 forward from 1.3.) [Ken Coar]
2972 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
2973 DuplicateHandle on an IOCompletionPort (a practice which
2974 MS "discourages"). The new model does not rely on associating
2975 the completion port with the listening sockets, thus the
2976 completion port can be completely managed within the child
2977 process. A dedicated thread accepts connections off the network,
2978 then calls PostQueuedCompletionStatus() to wake up worker
2979 threads blocked on the completion port.
2982 *) Bring forward the --suexec-umask option which allows the
2983 builder to preset the umask for suexec processes. [Ken Coar]
2985 *) Add a -V flag to suexec, which causes it to display the
2986 compile-time settings with which it was built. (Only
2987 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
2989 *) Mod_include should always unset the content-length if the file is
2990 going to be passed through send_parsed_content. There is no to
2991 determine if the content will change before actually scanning the
2992 entire content. It is far safer to just remove the C-L as long
2993 as we are scanning it. [Ryan Bloom]
2995 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
2996 request and not Proxy-Authenticate.
2997 [Graham Leggett <minfrin@sharp.fm>]
2999 Changes with Apache 2.0.14
3001 *) Fix content-length computation. We ONLY compute a content-length if
3002 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
3003 or we already have all the data. [Ryan Bloom]
3005 *) Report unbounded containers in the config file. Previously, a typo
3006 in the </container> directive could result in the rest of the config
3007 file being silently ignored, with undesired defaults used.
3010 *) Make the old_write filter use the ap_f* functions for the buffering.
3013 *) Move more code from the http module into the core server. This
3014 is core code, basically the default handler, the default input
3015 and output filters, and all of the core configuration directives.
3016 All of this code is required in order for the server to work, with or
3017 without HTTP. The server is closer to working without the HTTP
3018 module, although there is still more to do. [Ryan Bloom]
3020 *) Fix a number of SGI compile warnings throughout the server. Fix some
3021 bad parameters to apr_bucket_read(). Fix a bad statement in
3022 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
3023 consistently; we were mixing apr_time_t and time_t in invalid ways
3024 before. In load_file(), call apr_dso_error() instead of
3025 apr_strerror() so that we get a more specific string on some platforms.
3026 PR #6980 [Jeff Trawick]
3028 *) Allow modules to query the MPM about it's execution profile. This
3029 query API can and should be extended in the future, but for now,
3030 max_daemons, and threading or forking is a very good start.
3031 [Jon Travis <jtravis@covalent.net>]
3033 *) Modify mod_include to send blocks of data no larger than 9k.
3034 Without this, mod_include will wait until the whole file is parsed,
3035 or the first tag is found to send any data to the client.
3036 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3038 *) Fix mod_info, so that <Directory> and <Location> directives are
3039 not displayed twice when displaying the current configuration.
3040 [Ryan Morgan <rmorgan@covalent.net>]
3042 *) Add config directives to override DEFAULT_ERROR_MSG and
3043 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
3044 [Dan Rench <drench@xnet.com>]
3046 *) Get mod_info building and loading on Win32. [William Rowe]
3048 *) Begin to move protocol independant functions out of mod_http. The goal
3049 is to have only functions that are HTTP specific in the http directory.
3052 Changes with Apache 2.0.13
3054 *) Don't assume that there will always be multiple calls to the byterange
3055 filter. It is possible that we will need to do byteranges with only
3056 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
3058 *) Move the error_bucket definition from the http module to the
3059 core server. Every protocol will need this ability, not just
3062 Changes with Apache 2.0.12
3064 *) Modify mod_file_cache to save pre-formatted strings for
3065 content-length and last-modified headers for performance.
3066 [Mike Abbot <mja@trudge.engr.sgi.com>]
3068 *) Namespace protect IOBUFSIZ since it is exposed in the API.
3069 [Jon Travis <jtravis@covalent.net>]
3071 *) Use "Basic" authentication instead of "basic" in ab, as the spec
3072 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
3074 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
3075 without ever filling it out. This fixes PR 7271.
3076 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
3077 Cliff Woolley <cliffwoolley@yahoo.com>]
3079 *) Add a couple of GCC attribute tags to printf style functions.
3080 [Jon Travis <jtravis@covalent.net>]
3082 *) Add the correct language tag for interoperation with the Taiwanese
3083 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
3085 *) Migrate the perchild MPM to use the new apr signal child, and
3086 APR thread functions. [Ryan Bloom]
3088 *) Close one copy of the CGI's stdout before creating the new process.
3089 The CGI will still have stdout, because we have already dup'ed it.
3090 This keeps Apache from waiting forever to send the results of a CGI
3091 process that has forked a long-lived child process.
3092 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3094 *) Remove the rest of the pthreads functions from the threaded MPM.
3095 This requires the APR support for a signal thread that was just
3098 *) Make mod_dir use a fixup for sending a redirect to the browser.
3099 Before this, we were using a handler, which doesn't make much
3100 sense, because the handler wasn't generating any data, it would
3101 either return a redirect error code, or DECLINED. This fits the
3102 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
3104 *) Make the threaded MPM use APR threads instead of pthreads.
3107 *) Get mod_tls to the point where it actually appears to work in all cases.
3110 *) implement --enable-modules and --enable-mods-shared for "all" and
3111 "most". [Greg Stein]
3113 *) Move the threaded MPM to use APR locks instead of pthread locks.
3116 *) Rename mpmt_pthread to threaded. This is more in line with the
3117 fact that mpmt_pthread shouldn't be using pthreads directly, and
3118 it is a smaller name that doesn't tie into anything.
3121 *) Rename the module structures so that the exported symbol matches
3122 the file name, and it is easier to automate the installation
3123 process (generating LoadModule directives from the module filenames).
3126 *) Remove the coalesce filter. With the ap_f* functions, this filter
3127 is no longer needed. [Ryan Bloom]
3129 Changes with Apache 2.0.11
3131 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
3132 added feature of allowing a uid/gid per child process. If no
3133 uid/gid is specified, then Perchild behaves exactly like dexter.
3136 *) Get perchild building again. [Ryan Bloom]
3138 *) Don't disable threads just because we are using the prefork MPM.
3139 If somebody wants to compile without threads, they must now add
3140 --disable-threads to the configure command line. [Ryan Bloom]
3142 *) Begin to move the calls to update_child_status into common code, so
3143 that each individual MPM does not need to update the scoreboard itself.
3146 *) Allow mod_tls to compile under Unix boxes where openssl has been
3147 installed to the system include files.
3148 [Gomez Henri <new-httpd@slib.fr>]
3150 *) Cleanup the mod_tls configure process. This should remove any need
3151 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
3152 configure doesn't check that yet. [Ryan Bloom]
3154 *) Add a very early prototype of SSL support (in mod_tls.c). It is
3155 vital that you read modules/tls/README before attempting to build
3158 *) Fix a potential seg fault on all platforms. David Reid fixed this
3159 on BEOS, but the problem could happen anywhere, so we don't want
3160 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
3162 *) Add new LogFormat directive, %D, to log time it takes to serve a
3163 request in microseconds. [Bill Stoddard]
3165 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
3166 SetOutputFilter. This corresponds nicely with the other Set
3167 directives, which operate on containers while the Add* directives
3168 tend to work directly on extensions. [Ryan Bloom]
3170 *) Cleanup the header handling a bit. This uses the apr_brigade_*
3171 functions for the buffering so that we don't need to compute
3172 the length of the headers before we actually create the header
3173 buffer. [Ryan Bloom]
3175 *) Allow filters to buffer data using the ap_f* functions. These have
3176 become macros that resolve directly to apr_brigade_*.
3179 *) Get the Unix MPM's to do a graceful restart again. If we are going
3180 to register a cleanup with ap_cleanup_scoreboard, then we have to
3181 kill the cleanup with the same function, and that function can't be
3182 static. [Ryan Bloom]
3184 *) Install all required header files. Without these, it was not
3185 possible to compile some modules outside of the server.
3188 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
3189 forward from 1.3 to 2.0, we missed a single line, which broke regex
3190 aliases. [Ryan Bloom]
3192 *) We have a poor abstraction in the protocol. This is a temporary
3193 hack to fix the bug, but it will need to be fixed for real. If
3194 we find an error while sending out a custom error response, we back
3195 up to the first non-OK request and send the data. Then, when we send
3196 the EOS from finalize_request_protocol, we go to the last request,
3197 to ensure that we aren't sending an EOS to a request that has already
3198 received one. Because the data is sent on a different request than
3199 the EOS, the error text never gets sent down the filter stack. This
3200 fixes the problem by finding the last request, and sending the data
3201 with that request. [Ryan Bloom]
3203 *) Make the server status page show the correct restart time, and
3204 thus the proper uptime. [Ryan Bloom]
3206 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
3207 should reduce the amount of duplicate code that is required to
3208 create CGI processes.
3209 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3211 *) ap_new_connection() closes the socket and returns NULL if a socket
3212 call fails. Usually this is due to a connection which has been
3213 reset. [Jeff Trawick]
3215 *) Move the Apache version information out of httpd.h and into release.h.
3216 This is in preparation for the first tag with the new tag and release
3217 system. [Ryan Bloom]
3219 *) Begin restructuring scoreboard code to enable adding back in
3220 the ability to use IPC other than shared memory.
3221 Get mod_status working on Windows again. [Bill Stoddard]
3223 *) Make mod_status work with 2.0. This will work for prefork,
3224 mpmt_pthread, and dexter. [Ryan Bloom]
3226 *) Correct a typo in httpd.conf.
3227 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
3229 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
3231 *) Get the correct IP address if ServerName isn't set and we can't
3232 find a fully-qualified domain name at startup.
3233 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
3235 *) Make mod_cgid work with SuExec. [Ryan Bloom]
3237 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
3238 'extra' stat's for user/group since they should never occur, and now
3239 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
3240 volumes. [William Rowe]
3242 *) Adopt apr features to simplify mod_includes. This changes the
3243 behavior of the USER_NAME variable, unknown uid's are now reported
3244 as USER_NAME="<unknown>" rather than the old user#000 result.
3245 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
3247 *) Adopt apr features for simplifing mod_userdir, and accept the new
3248 Win32/OS2 exceptions without hiccuping. [William Rowe]
3250 *) Replace configure --with-optim option by using and saving the
3251 environment variable OPTIM instead. This is needed because configure
3252 options do not support multiple flags separated by spaces.
3255 *) Fix some byterange handling. If we get a byte range that looks like
3256 "-999999" where that is past the end of the file, we should return
3257 a PARTIAL CONTENT status code, and return the whole file as one big
3258 byterange. This matches the 1.3 handling now. [Ryan Bloom]
3260 *) Make the error bucket a real meta-data bucket. This means that the
3261 bucket length is 0, and a read returns NULL data. If one of these
3262 buckets is passed down after the headers are sent, this data will
3263 just be ignored. [Greg Stein]
3265 *) The prefork MPM wasn't killing child processes correctly if a restart
3266 signal was received while the process was serving a request. The child
3267 process would become the equivalent of a second parent process. If
3268 we break out of the accept loop, then we need to do die after cleaning
3269 up after ourselves. [Ryan Bloom]
3271 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
3272 restarts. [Ryan Bloom]
3274 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
3275 the most optimal APR_FINFO_wanted bits. This spares Win32 from
3276 performing very expensive owner, group and permission lookups
3277 and allows the server to function until these apr_finfo_t fields
3278 are implemented under Win32. [William Rowe]
3280 *) Support for typedsafe optional functions - that is functions exported by
3281 optional modules, which, therefore, may or may not be present, depending
3282 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
3283 for sample code. [Ben Laurie]
3285 *) filters can now report an HTTP error to the server. This is done
3286 by sending a brigade where the first bucket is an error_bucket.
3287 This bucket is a simple bucket that stores an HTTP error and
3288 a string. Currently the string is not used, but it may be needed
3289 to output an error log. The http_header_filter will find this
3290 bucket, and output the error text, and then return
3291 AP_FILTER_ERROR, which informs the server that the error web page
3292 has already been sent. [Ryan Bloom]
3294 *) If we get an error, then we should remove all filters except for
3295 those critical to serving a web page. This fixes a bug, where
3296 error pages were going through the byterange filter, even though
3297 that made no sense. [Ryan Bloom]
3299 *) Relax the syntax checking of Host: headers in order to support
3300 iDNS. PR#6635 [Tony Finch]
3302 *) Cleanup the byterange filter to use the apr_brigade_partition
3303 and apr_bucket_copy functions. This removes a lot of very messy
3304 code, and hopefully makes this filter more stable.
3307 *) Remove AddModule and ClearModuleList directives. Both of these
3308 directives were used to ensure that modules could be enabled
3309 in the correct order. That requirement is now gone, because
3310 we use hooks to ensure that modules are in the correct order.
3313 *) When SuExec is specified, we need to add it to the list of
3314 targets to be built. If we don't, then any changes to the
3315 configuration won't affect SuExec, unless 'make suexec' is
3316 specifically run. [Ryan Bloom]
3318 *) Cleaned out open_file from mod_file_cache, as apr now accepts
3319 the APR_XTHREAD argument to open a file for consumption by
3320 parallel threads on win32. [William Rowe]
3322 *) Correct a bug in determining when we follow symlinks. The code
3323 expected a stat -1 result, not an apr_status_t positive error.
3324 Also check if the APR_FINFO_USER fields are valid before we
3325 follow the link. [William Rowe]
3327 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
3328 mpm_common.c. These functions are only valid on some platforms,
3329 so they should not be in the main-line code. [Ryan Bloom]
3331 *) Remove ap_chdir_file(). This function is not thread-safe,
3332 and nobody is currently using it. [Ryan Bloom]
3334 *) Do not try to run make depend if there are no .c files in the
3335 current directory, doing so makes `make depend` fail.
3338 *) Update highperformance.conf to work with either prefork or
3339 pthreads mpms. [Greg Ames]
3341 *) Stop checking to see if this is a pipelined request if we know
3342 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
3343 This keeps us from making an extra read call when serving a 1.0
3344 request. [Ryan Bloom and Greg Stein]
3346 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
3347 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
3348 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
3350 *) Fix the RFC number mentioned when complaining about a missing
3351 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
3353 *) Fix an endless loop in ab which occurred when ab was posting
3354 and the server dropped the connection unexpectedly.
3357 *) Fix a segfault while handling request bodies in ap_http_filter().
3358 This problem has been seen with mod_dav usage as well as with
3359 requests where the body was just being discarded. [Jeff Trawick]
3361 *) Some adjustment on the handling and automatic setting (via
3362 hints.m4) of various compilation flags (eg: CFLAGS). Also,
3363 add the capability to specify flags (NOTEST_CFLAGS and
3364 NOTEST_LDFLAGS) which are used to compile Apache, but
3365 not used during the configuration process. Useful for
3366 flags like "-Werror". [Jim Jagielski]
3368 *) Stop using environment variables to force debug mode or
3369 no detach. We now use the -D command line argument to
3370 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
3371 [Greg Stein, Ryan Bloom]
3373 *) Change handlers to use hooks. [Ben Laurie]
3375 *) Stop returning copies of filenames from both apr_file_t and
3376 apr_dir_t. We pstrdup the filenames that we store in the
3377 actual structures, so we don't need to pstrdup the strings again.
3380 *) mod_cgi: Fix some problems where the wrong error value was being
3381 traced. [Jeff Trawick]
3383 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
3386 *) Add generic hooks. [Ben Laurie]
3388 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
3390 *) Fix a segfault caused by mod_ext_filter when the external filter
3391 program does not exist. [Jeff Trawick]
3393 *) Fix an output truncation error when on an HTTP >= 1.0 request an
3394 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
3395 was served through mod_charset_lite (or anything else that would
3396 create a transient bucket in this size range). ap_bucket_make_heap()
3397 silently failed (fixed), transient_setaside() discovered it, but
3398 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
3400 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
3401 is that some browsers send extra lines at the end of POST requests, and
3402 we don't want to delay sending data back to the user just because the
3403 browser isn't well behaved. [Ryan Bloom]
3405 *) Get SuEXEC working again. We can't send absolute paths to suExec
3406 because it refuses to execute those programs. SuEXEC also wasn't
3407 always recognizing configuration changes made using the autoconf
3410 *) Allow the buildconf process to find the config.m4 files in the correct
3411 order. Basically, we can now name config.m4 files as config\d\d.m4,
3412 and we will sort them correctly when inserting them into the build
3413 process. [Ryan Bloom]
3415 *) Get mod_cgid to use apr calls for creating the actual CGI process.
3416 This also allows mod_cgid to use ap_os_create_priviledged_process,
3417 thus allowing for SuExec execution from mod_cgid. Currently, we do
3418 not support everything that standard SuExec supports, but at least
3419 it works minimally now. [Ryan Bloom]
3421 *) Allow SuExec to be configured from the ./configure command line.
3424 *) Update some of the docs in README and INSTALL to reflect some of
3425 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
3427 *) If we get EAGAIN returned from the call to apr_sendfile, then we
3428 need to call sendfile again. This gets us serving large files
3429 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
3431 *) Get the support programs building cleanly again.
3432 [Cliff Woolley <cliffwoolley@yahoo.com>]
3434 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
3435 current directory logic now backs up over bin/ to determine the
3436 server root from the Apache.exe path.
3438 *) Apache/Win32 now follows the standard conventions of mod_foo.so
3439 loadable modules, dynamic libs are all named libfoo.dll, and the
3440 makefile.win populates the include, lib and libexec directories.
3442 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
3443 Apache gets IPv6 listening sockets by default. Additionally, the
3444 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
3445 numeric address strings (e.g., "Listen [fe80::1]:8080").
3448 *) Modify the install directory layout. Modules are now installed in
3449 modules/. Shared libraries should be installed in libraries/, but
3450 we don't have any of those on Unix yet. All install directories
3451 are modifyable at configure time. [Ryan Bloom]
3453 *) Install all header files in the same directory on Unix. [Ryan Bloom]
3455 *) Get the functions in server/linked into the server, regardless of
3456 which modules linked into the server. This uses the same hack
3457 for Apache that we use for APR and apr-util to ensure all of the
3458 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
3459 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
3460 the scripts a bit easier.
3463 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
3464 on the query, and remove IPv4 dependencies. [Jeff Trawick]
3466 *) Get all of the auth modules to the point that they will install and
3467 be loadable into the server. Our new build/install mechanism expects
3468 that all modules will have a common name format. The auth modules
3469 didn't use that format, so we didn't install them properly.
3472 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
3473 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
3475 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
3477 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
3478 after the end of the response. [Ryan Bloom]
3480 *) Get byterange requests working with responses that do not have a
3481 content-length. Because of the way byterange requests work, we have to
3482 have all of the data before we can actually do the byterange, so we
3483 can compute the content-length in the byterange filter.
3486 *) Get exe CGI's working again on Windows.
3489 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
3490 they keep track of whether or not their post config hook has been
3491 called before. Instead of a static variable (which is replaced when
3492 the DSO is loaded a second time), use userdata in the process pool.
3495 Changes with Apache 2.0a9
3497 *) Win32 now requires perl to complete the final install step for users
3498 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
3499 and installs the conf, htdocs and htdocs/manual directories.
3502 *) Make mod_include use a hash table to associate directive tags with
3503 functions. This allows modules to implement their own SSI tags easily.
3504 The idea is simple enough, a module can insert it's own tag and function
3505 combination into a hash table provided by mod_include. While mod_include
3506 parses an SSI file, when it encounters a tag in the file, it does a
3507 hash lookup to find the function that implements that tag, and passes
3508 all of the relevant data to the function. That function is then
3509 responsible for processing the tag and handing the remaining data back
3510 to mod_include for further processing.
3511 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3513 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
3514 fewer parameters: the local and remote socket addresses were removed
3515 from the parameter list because all required information is available
3516 via the APR socket. [Jeff Trawick]
3518 *) Distribution directory structure reorganized to reflect a
3519 normal source distribution with external install targets.
3522 *) The MPMs that need multiple segments of shared memory now create
3523 two apr_shmem_t variables, one for each shared memory allocation.
3524 the problem is that we can't determine how much memory will be required
3525 for shared memory allocations once we try to allocate more than one
3526 variable. The MM code automatically aligns the shared memory allocations,
3527 so we end up needing to pad the amount of shared memory we want based
3528 on how many variables will be allocated out of the shared memory segment.
3529 It is just easier to create a second apr_shmem_t variable, and two
3530 shmem memory blocks.
3533 *) Cleanup the export list a bit. This creates a single unified list of
3534 functions exported by APR. The export list is generated at configure
3535 time, and that list is then used to generate the exports.c file.
3536 Because of the way the export list is generated, we only export those
3537 functions that are valid on the platform we are building on.
3540 *) Enable logging the cookie with mod_log_config
3541 [Sander van Zoest <sander@covalent.net>]
3543 *) Fix a segfault in mod_info when it reaches the end of the configuration.
3546 *) Added lib/aputil/ as a placeholder for utility functions which are not
3547 specific to the Apache HTTP Server (but do not make sense with APR).
3548 The first utility is "apu_dbm": a set of functions to work with DBM
3549 files. This first version can be compiled for SDBM or GDBM databases.
3552 *) Complete re-write of mod_include. This makes mod_include a filter that
3553 uses buckets directly. This has now served the FAQ correctly.
3554 [Paul Reder <rederpj@raleigh.ibm.com>]
3556 *) Allow modules to specify the first filter in a sub_request when
3557 making the sub_request. This keeps modules from having to change the
3558 output_filter immediately after creating the sub-request, and therefore
3559 skip the sub_req_output_filter. [Ryan Bloom]
3561 *) Update ab to accept URLs with IPv6 literal address strings (in the
3562 format described in RFC 2732), and to build Host header fields in
3563 the same format. This allows IPv6 literal address strings to be
3564 used with ab. This support has been tested against Apache 1.3 with
3565 the KAME patch, but Apache 2.0 does not yet work with this format
3566 of the Host header field. [Jeff Trawick]
3568 *) Accomodate an out-of-space condition in the piped logs and the
3569 rotatelogs.c code, and no longer churn log processes for this
3570 condition. [Victor J. Orlikowski]
3572 *) Add support for partial writes with apr_sendfile() to core_output_filter.
3575 Changes with Apache 2.0a8
3577 *) Add a directive to mod_mime so that filters can be associated with
3581 *) Get multi-views working again. We were setting the path_info
3582 field incorrectly if we couldn't find the specified file.
3585 *) Fix 304 processing. The core should never try to send the headers
3586 down the filter stack. Always, just setup the table in the request
3587 record, and let the header filter convert it to data that is ready
3591 *) More fixes for the proxy. There are still bugs in the proxy code,
3592 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
3596 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
3599 *) APR: Add new apr_getopt_long function to handle long options.
3600 [B. W. Fitzpatrick <fitz@red-bean.com>]
3602 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
3603 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
3604 hostname resolution/address string parsing and building
3605 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
3606 of one of the apr_sockaddr_t structures for a socket. Change
3607 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
3609 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
3610 I have proxied pages with it, cleanup will commence soon.
3613 *) Make the proxy work with filters. This isn't perfect, because we
3614 aren't dealing with the headers properly. [Ryan Bloom]
3616 *) Do not send a content-length iff the C-L is 0 and this is a head
3617 request. [Ryan Bloom]
3619 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
3620 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
3622 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
3624 *) Get the default_handler to stop trying to deal with HEAD requests.
3625 The idea is to let the content-length filter compute the C-L before
3626 we try to send the data. If we can get the C-L correctly, then we
3627 should send it in the HEAD response.
3630 *) The Header filter can now determine if a body should be sent based
3631 on r->header_only. The general idea of this is that if we delay
3632 deciding to send the body, then we might be able to compute the
3633 content-length correctly, which will help caching proxies to cache
3634 our data better. Any handler that doesn't want to try to compute
3635 the content-length can just send an EOS bucket without data and
3636 everything will just work.
3639 *) Add the referer to the error log if one is available.
3640 [Markus Gyger <mgyger@itr.ch>]
3642 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
3643 change, the root of the configuration tree has been exposed to modules
3645 [Ryan Morgan <rmorgan@covalent.net>]
3647 *) Get the core_output_filter to use the bucket interface directly.
3648 This keeps us from calling the content-length filter multiple times
3649 for a simple static request.
3652 *) We are sending the content-type correctly now.
3653 [Ryan Bloom and Will Rowe]
3655 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
3656 a bogus bytes-sent value when the only thing being sent was trailers
3657 and writev() returned an error (or EAGAIN). [Jeff Trawick]
3659 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
3660 hints file to determine which platforms define
3661 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
3664 *) APR: add apr_get_home_directory() [Jeff Trawick]
3666 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
3668 *) Not all platforms have INADDR_NONE defined by default. Apache
3669 used to make this check and define INADDR_NONE if appropriate,
3670 but APR needs the check too, and I suspect other applications will
3671 as well. APR now defines APR_INADDR_NONE, which is always a valid
3672 value on all platforms.
3673 [Branko Èibej <brane@xbc.nu>]
3675 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
3676 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
3678 *) Relax the syntax checking of Host: headers in order to support
3679 iDNS. PR#6635 [Tony Finch]
3681 *) When reading from file buckets we convert to an MMAP if it makes
3682 sense. This also simplifies the default handler because the
3683 default handler no longer needs to try to create MMAPs.
3686 *) BUFF has been removed from the main server. The BUFF code will remain
3687 in the code until it has been purged from the proxy module as well.
3690 *) Byteranges have been completely re-written to be a filter. This
3691 has been tested, and I believe it is working correctly, but it could
3692 doesn't work for the Adobe Acrobat plug-in. The output almost matches
3693 the output from 1.3, the only difference being that 1.3 includes
3694 a content-length in the response, and this does not.
3697 *) APR read/write functions and bucket read functions now operate
3698 on unsigned integers, instead of signed ones. It doesn't make
3699 any sense to use signed ints, because we return the error codes,
3700 so if we have an error we should report 0 bytes read or written.
3703 *) Always compute the content length, whether it is sent or not.
3704 The reason for this, is that it allows us to correctly report
3705 the bytes_sent when logging the request. This also simplifies
3706 content-length filter a bit, and fixes the actual byte-reporing
3707 code in mod_log_config.c
3710 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
3711 it says, because it was only used by EOS and FLUSH buckets. Since
3712 neither of those are required at the end of a brigade, this was
3713 really signifying FLUSH_THE_DATA, but that can be determined better
3714 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
3715 buckets now return a length of 0, which is actually the amount of data
3716 read, so they make more sense.
3719 *) Allow the core_output_filter to save some data past the end of a
3720 request. If we get an EOS bucket, we only send the data if it
3721 makes sense to send it. This allows us to pipeline request
3722 responses. As a part of this, we also need to allocate mmap
3723 buckets out of the connection pool, not the request pool. This
3724 allows the mmap to outlive the request.
3727 *) Make blocking and non-blocking bucket reads work correctly for
3728 sockets and pipes. These are the only bucket types that should
3729 have non-blocking reads, because the other bucket types should
3730 ALWAYS be able to return something immediately.
3733 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
3734 server, but use Ctrl+Break to initiate a graceful restart
3735 instead of duplicating behavior. [John Sterling]
3737 *) Patch mod_autoindex to set the Last-Modified header based on
3738 the directory's mtime, and add the ETag header. [William Rowe]
3740 *) Merge the 1.3 patch to add support for logging query string in
3741 such a way that "%m %U%q %H" is the same as "%r".
3744 *) Port three log methods from mod_log_config 1.3 to 2.0:
3745 CLF compliant '-' byte count, method and protocol.
3748 *) Add a new LogFormat directive, %c, that will log connection
3749 status at the end of the response as follows:
3750 'X' - connection aborted before the response completed.
3751 '+' - connection may be kept-alive by the server.
3752 '-' - connection will be closed by the server.
3755 *) Expand APR for WinNT to fully accept and return utf-8 encoded
3756 Unicode file names and paths for Win32, and tag the Content-Type
3757 from mod_autoindex to reflect that charset if the the feature
3758 macro APR_HAS_UNICODE_FS is true. [William Rowe]
3760 *) Compute the content length (and add appropriate header field) for
3761 the response when no content length is available and we can't use
3762 chunked encoding. [Jeff Trawick]
3764 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
3765 so that content input filters get dechunked data when using
3766 the default handler. Also removed REQUEST_CHUNKED_PASS.
3769 *) Add mod_ext_filter as an experimental module. This module allows
3770 the administrator to use external programs as filters. Currently,
3771 only filtering of output is supported. [Jeff Trawick]
3773 *) Most Apache functions work on EBCDIC machines again, as protocol
3774 data is now translated (again). [Jeff Trawick]
3776 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
3777 the EBCDIC support. They are noops on ASCII machines, so this
3778 type of translation doesn't have to be surrounded by #ifdef
3779 CHARSET_EBCDIC. [Jeff Trawick]
3781 *) Fix mod_include. tag commands work again, and the server will
3782 send the FAQ again. This also allows mod_include to set aside
3783 buckets that include partial buckets.
3784 [Ryan Bloom and David Reid]
3786 *) Add suexec support back. [Manoj Kasichainula]
3788 *) Lingering close now uses the socket directly instead of using
3789 BUFF. This has been tested, but since all we can tell is that it
3790 doesn't fail, this needs to be really hacked on.
3793 *) Allow filters to modify headers and have those headers be sent to
3794 the client. The idea is that we have an http_header filter that
3795 actually sends the headers to the network. This removes the need
3796 for the BUFF to send headers.
3799 *) Charset translation: mod_charset_lite handles translation of
3800 request bodies. Get rid of the xlate version of ap_md5_digest()
3801 since we don't compute digests of filtered (e.g., translated)
3802 response bodies this way anymore. (Note that we don't do it at
3803 all at the present; somebody needs to write a filter to do so.)
3806 *) Input filters and ap_get_brigade() now have a input mode parameter
3807 (blocking, non-blocking, peek) instead of a length parameter.
3810 *) Update the mime.types file to the registered media types as
3811 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
3814 *) Namespace protect some macros declared in ap_config.h
3817 *) Support HTTP header line folding with input filtering.
3820 *) Mod_include works again. This should still be re-written, but at
3821 least now we can serve an SHTML page again.
3824 *) Begin to remove BUFF from the core. Currently, we keep a pointer
3825 to both the BUFF and the socket in the conn_rec. Functions that
3826 want to use the BUFF can, functions that want to use the socket,
3827 can. They point to the same place.
3830 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
3831 [Tomas "Ögren" <stric@ing.umu.se>]
3833 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
3834 associated pool goes away. (APR pipes on OS/2 were already had this
3835 logic.) This resolvs a fatal file descriptor leak with CGIs.
3838 *) The final line of the config file was not being read if there was
3839 no \n at the end of it. This was caused by apr_fgets returning
3840 APR_EOF even though we had read valid data. This is solved by
3841 making cfg_getline check the buff that was returned from apr_fgets.
3842 If apr_fgets return APR_EOF, but there was data in the buf, then we
3843 return the buf, otherwise we return NULL.
3846 *) Piped logs work again in the 2.0 series.
3849 *) Restore functionality broken by the mod_rewrite security fix:
3850 rewrite map lookup keys and default values are now expanded
3851 so that the lookup can depend on the requested URI etc.
3852 PR #6671 [Tony Finch]
3854 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
3855 security bug in some mass virtual hosting configurations
3856 that can allow a remote attacker to retrieve some files
3857 on the system that should be inaccessible. [Tony Finch]
3859 *) Add a pool bucket type. This bucket is used for data allocated out
3860 of a pool. If the pool is cleaned before the bucket is destroyed, then
3861 the data is converted to a heap bucket, allowing it to survive the
3865 *) Add a flush bucket. This allows modules to signal that the filters
3866 should all flush whatever data they currently have. There is no way
3867 to actually force them to do this, so if a filter ignores this bucket,
3868 that's life, but at least we can try with this.
3871 *) Add an output filter for sub-requests. This filter just strips the
3872 EOS bucket so that we don't confuse the main request's core output
3873 filter by sending multiple EOS buckets. This change also makes sub
3874 requests start to send EOS buckets when they are finished.
3877 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
3878 makes ap_bucket_destroy a return void, which is okay because it
3879 used to always return APR_SUCCESS, and nobody ever checked its
3880 return value anyway.
3881 [Cliff Woolley <cliffwoolley@yahoo.com>]
3883 *) Remove the index into the bucket-type table from the buckets
3884 structure. This has now been replaced with a pointer to the
3885 bucket_type. Also add some macros to test the bucket-type.
3888 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
3889 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
3890 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
3891 All _VAR_ flavors changes to _DATA to be absolutely clear.
3894 *) Add support for /, //, //servername and //server/sharename
3895 parsing of <Directory> blocks under Win32 and OS2.
3896 [Tim Costello, William Rowe, Brian Harvard]
3898 *) Remove the function pointers from the ap_bucket type. They have been
3899 replaced with a global table. Modules are allowed to register bucket
3900 types and use then use those buckets.
3903 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
3904 once we finish writing the request body to the cgi child process;
3905 otherwise, the client doesn't hit EOF on stdin. Small request bodies
3906 worked without this change (for reasons I don't understand), but large
3907 ones didn't. [Jeff Trawick]
3909 *) Remove file bucket specific information from the ap_bucket type.
3910 This has been moved to a file_bucket specific type that hangs off
3911 the data pointer in the ap_bucket type.
3914 *) Input filtering now has a third argument. This is the amount of data
3915 to read from lower filters. This argument can be -1, 0, or a positive
3916 number. -1 means give me all the data you have, I'll deal with it and
3917 let you know if I need more. 0 means give me one line and one line
3918 only. A positive number means I want no more than this much data.
3920 Currently, only 0 and a positive number are implemented. This allows
3921 us to remove the remaining field from the conn_rec structure, which
3925 *) Big cleanup of the input filtering. The goal is that http_filter
3926 understands two conditions, headers and body. It knows where it is
3927 based on c->remaining. If c->remaining is 0, then we are in headers,
3928 and http_filter returns a line at a time. If it is not 0, then we are
3929 in body, and http_filter returns raw data, but only up to c->remaining
3930 bytes. It can return less, but never more.
3931 [Greg Ames, Ryan Bloom, Jeff Trawick]
3933 *) mod_cgi: Write all of the request body to the child, not just what
3934 the kernel would accept on the first write. [Jeff Trawick]
3936 *) Back out the change that moved the brigade from the core_output_filters
3937 ctx to the conn_rec. Since all requests over a given connection
3938 go through the same core_output_filter, the ctx pointer has the
3942 *) Fix another bug in the send_the_file() read/write loop. A partial
3943 send by apr_send would cause unsent data in the read buffer to
3944 get clobbered. Complete making send_the_file handle partial
3945 writes to the network.
3948 *) Fix a couple of type fixes to allow compilation on AIX again
3949 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
3951 *) Fix bug in send_the_file() which causes offset to be ignored
3952 if there are no headers to send.
3955 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
3956 filter. Useful for supporting Windows 9* with a binary
3957 compiled on Windows NT.
3960 Changes with Apache 2.0a7
3962 *) Reimplement core_output_filter to buffer/save bucket brigades
3963 across multiple calls to the core_filter. The brigade will be
3964 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
3965 thresholds are hit or the EOS bucket is received.
3968 *) Create experimental filter (buffer_filter) that coalesces bytes
3969 into one large buffer before invoking the next filter in the
3970 chain. This filter is particularly useful with the current
3971 implementation of mod_autoindex when it inserted above the
3972 chunk_filter. mod_autoindex generates a lot of brigades that
3973 containing buckets holding just a few bytes each. The
3974 buffer_filter coalesces these buckets into a single large bucket.
3977 *) Add apr_sendfile() support into the core_output_filter.
3980 *) Add apr_sendv() support into the core_output_filter.
3983 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
3984 [Mike Abbott <mja@sgi.com>]
3986 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
3987 make much sense, because Apache uses buckets instead of BUFFs now.
3990 *) send_the_file now falls back to a read/write loop on platforms that
3991 do not have sendfile.
3992 [Ryan Bloom and Brian Havard]
3994 *) Install apachectl correctly, and substitute the proper values so
3995 that it works again. [Ryan Bloom]
3997 *) Better(??) handle platforms that lack sendfile().
4000 *) APR now has UUID generation/formatting/parsing support.
4003 *) Begin the http_filter. This is an input filter that understands
4004 the absolute basic amount required to parse an HTTP Request. The
4005 goal is to be able to split headers from request body before passing
4006 the data back to the other filters.
4009 *) Bring forward from 1.3.13 the config directory implementation
4012 *) install apxs if it is created
4015 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
4016 conversions. [William Rowe]
4018 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
4019 ap_add_output_filter(). [Jeff Trawick]
4021 *) Multiple build and configuration fixes
4024 -add datadir and localstatedir substitutions
4026 -fix logfilename misspelling
4027 -fix evaluation of installation dir variables and
4028 -replace $foobar by $(foobar) to be usefull in the makefile
4032 -add rules for cross-compiling in rules.mk. Okay, rule to check for
4033 $CC_FOR_BUILD is still missing
4034 -use CHECK_TOOL instead of CHECK_PROG for ranlib
4035 -add missing "AR=@AR@" to severaly Makefile.in's
4036 -cache result for "struct rlimit"
4037 -compile all helper programs with native and cross compiler
4038 and use the native version to generate header file
4039 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
4041 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
4043 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
4045 *) Fix a bug where a client which only sends \n to delimit header
4046 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
4047 message. Start working on ebcdic co-existance with input
4049 [William Rowe, Greg Ames]
4051 *) If mod_so is enabled in the server always create libexec, even
4052 if there are no modules installed in this directory. This is a
4053 requirement for APXS to work correctly.
4056 *) Connection oriented output filters are now stored in the
4057 conn_rec instead of the request_rec. This allows us to add the
4058 output filter in the pre-connection phase instead of the
4059 post_read_request phase, which keeps us from trying to write an
4060 error page before we have a filter to write to the network.
4061 [Ryan Bloom, Jeff Trawick, and Greg Ames]
4063 *) Cleaning up an mmap bucket no longer deletes the mmap. An
4064 mmap can be used across multiple buckets (default_handler with
4065 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
4066 the mmap itself can't be associated with the bucket.
4069 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
4072 *) Radical surgery to improve mod_isapi support under Win32.
4073 Includes a number of newer ServerSupportFunction calls, support
4074 for ReadClient (in order to retrieve POSTs greater than 48KB),
4075 and general bug fixes to more reliably load ISAPI .dll's and
4076 prevent leaking handle resources. Note: There are still
4077 discrepancies between IIS's and Apache's ServerVariables, and
4078 async calls are still not supported. Additional warnings are
4079 logged to facilitate debugging of unsupported ISAPI calls.
4082 *) Add input filtering to Apache. The basic idea for the input
4083 filters is the same as the ideas for output filters. The biggest
4084 difference is that instead of calling ap_pass_brigade, ap_get_brigade
4085 should be called, and the order of execution for the filter itself is
4086 different. When writing an output filter, a brigade is passed in,
4087 and filters operate directly on that brigade, when done, they call
4088 ap_pass_brigade. Input filters are the exact opposite. Because input
4089 is not a push operation, filters first call ap_get_brigade. When this
4090 function returns, the input filter will be left with a valid brigade.
4091 The input filter should then operate on the brigade, and return.
4094 *) Fix building on BSD/OS using its native make. The build system
4095 falls back to the BSD .include directive on that host platform.
4098 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
4099 SHA1 and plaintext password encodings. Make feature tests a
4100 bit more flexible. [William Rowe]
4102 *) Charset translation: mod_charset_lite handles output content
4103 translation in a filter. mod_charset_lite no longer ignores
4104 subrequests. A bunch of cruft related to BUFF's support for
4105 translating request and response bodies was removed.
4108 *) Move the addition of the CORE filter to the post_read_request
4109 hook in http_core.c. This removes the need to add the filter in
4110 multiple places and allows for an SSL module to be added much
4111 simpler. [Ryan Bloom]
4113 *) SECURITY: CVE-2000-0913 (cve.mitre.org)
4114 Fix a security problem that affects certain configurations of
4115 mod_rewrite. If the result of a RewriteRule is a filename that
4116 contains expansion specifiers, especially regexp backreferences
4117 $0..$9 and %0..%9, then it may be possible for an attacker to
4118 access any file on the web server. [Tony Finch]
4120 *) Fix a bug where errors that are detected during early request parsing
4121 don't produce visible HTTP error messages at the browser, because
4122 the core_filter wasn't present. [Greg Ames]
4124 *) Provide apr_socklen_t as a portability aid.
4125 [Victor J. Orlikowski]
4127 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
4128 as well as a comment arg to the add, adduser and update cmds.
4129 update allows the user to clear or preserve pw/groups/comment.
4130 Fixed a bug in dbmmanage that prevented the check option from
4131 parsing a password followed by :group... text. Corrected the
4132 seed calcualation for Win32 systems, and added -lsdbm support.
4135 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
4138 *) Avoid a segfault when parsing .htaccess files. An
4139 uninitialized tree pointer was passed to ap_build_config().
4142 *) Change the way that inet_addr & inet_network are checked for
4143 in APR's configure process to allow BeOS BONE to correctly
4144 find them. With this change BeOS BONE now builds from source
4145 with no problems. [David Reid]
4147 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
4148 the end of the parameters to execve() was stored in the wrong
4149 location, overlaying the storage beyond the newargs[] array and
4150 also passing uninitialized storage to execve(), which would
4151 sometimes fail with EFAULT. [Jeff Trawick]
4153 *) Fix a bug parsing configuration file containers. With a sequence
4154 like this in the config file
4156 <IfModule mod_kilroy.c>
4159 <IfModule mod_lovejoy.c>
4164 the second container would be terminated at the blank line due to
4165 sediment in the buffer from reading the prior </IfModule> and an
4166 error message would be generated for the real </IfModule> for the
4167 second container. Also due to this problem, any two characters
4168 could be used for "</" in the close of a container.
4171 *) ap_add_filter prototype changed to remove the ctx pointer. The
4172 pointer still remains in the filter structure, but it can not be
4173 a part of the ap_add_filter prototype. The reason is that when
4174 the core uses AddFilter to add a filter to the stack it doesn't
4175 know how to allocate the ctx pointer, or even how much memory should
4176 be allocated. The filters will have to be responsible for allocating
4177 the ctx memory when they need it.
4180 *) Add an AddFilter directive. This directive takes a list of filters
4181 that should be activated for the requested resource.
4184 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
4185 some other platforms). [Jeff Trawick]
4187 *) Modify mod_include to be a filter. Currently, it has only been tested
4188 on actual files, but it should work for CGI scripts too.
4191 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
4192 writes. apr_flush() for Unix: handle interrupted writes.
4195 *) NameVirtualHost can now take "*" as an argument instead of
4196 an IP address. This allows you to create a purely name-based
4197 virtual hosting server that does not have any IP addresses in
4198 the configuration file and which ignores the local address
4199 of any connections. PR #5595, PR #4455 [Tony Finch]
4201 *) Fix some compile warnings in mod_mmap_static.c
4202 [Mike Abbott <mja@sgi.com>]
4204 *) Fix chunking problem with CGI scripts. The general problem was that
4205 the CGI modules were adding an EOS bucket and then the core added an
4206 EOS bucket. The chunking filter finalizes the chunked response when it
4207 encounters an EOS bucket. Because two EOS buckets were sent, we
4208 finalized the response twice. The fix is to make sure we only send one
4209 EOS, by utilizing a flag in the request_rec.
4212 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
4213 and Win32. Previously, the first read from an apr_file_t set up via
4214 apr_put_os_file() would return a '\0'. [Jeff Trawick]
4216 *) Mod_cgid now creates a single element bucket brigade, with a pipe
4217 bucket, instead of using BUFF's and ap_r*.
4220 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
4221 [Mike Abbott <mja@sgi.com>]
4223 *) Remove ap_bopenf from buff code. This required modifying the file_cache
4224 code to use APR file's directly instead of going through BUFFs.
4227 *) Fix compile break on some platforms for mod_mime_magic.c
4228 [John K. Sterling <sterling@covalent.net>]
4230 *) Fix merging of AddDefaultCharset directive.
4231 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
4233 *) Minor revamp of the rlimit sections of code. We now test
4234 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
4235 is now "available" even if the platform doesn't support
4236 the rlimit family (it's just a noop though). [Jim Jagielski]
4238 *) Migrate the pre-selection of which MPM to use for specific
4239 platforms to hints.m4, which contains (or should contain)
4240 all platform specific "hints". [Jim Jagielski]
4242 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
4245 *) Add tables with non-string/binary values to APR.
4248 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
4251 *) Update PCRE to version 3.2. [Ryan Bloom]
4253 *) Change the way buckets' destroy functions are called so that
4254 they can be more directly used when changing the type of a
4255 bucket in place. [Tony Finch]
4257 *) Add generic support for reference-counting the resources used by
4258 buckets, and alter the HEAP and MMAP buckets to use it. Change
4259 the way buckets are initialised to support changing the type of
4260 buckets in place, and use it when setting aside TRANSIENT buckets.
4261 Change the implementation of TRANSIENT buckets so that it can be
4262 mostly shared with IMMORTAL buckets, which are now implemented.
4265 Changes with Apache 2.0a6
4267 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
4269 *) Add a chunking filter to Apache. This brings us one step closer
4270 to removing BUFF. [Ryan Bloom]
4272 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
4273 added to the stack is the last filter to be called. [Ryan Bloom]
4275 *) Apache 2.0 has been completely documented using Scandoc. The
4276 docs can be generated by running 'make docs'. [Ryan Bloom]
4278 *) Add filtered I/O to Apache. This is based on bucket brigades,
4279 Currently the buckets still use BUFF under the covers, but that
4280 should change quickly. The only currently written filter is the
4281 core filter which just calls ap_bwrite. [The Apache Group]
4283 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
4284 built with thread support. [Jeff Trawick]
4286 *) Abort configuration if --with-layout was specified and there's
4287 no layout definition file. [Ken Coar]
4289 *) Add support for '--with-port=n' option to configure. [Ken Coar]
4291 *) Add support for extension methods for the Allow response header
4292 field, and an API routine for accessing r->allowed and the
4293 list of extension methods in a unified manner. [Ken Coar]
4295 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
4296 [Rob Simonson <simo@us.ibm.com>]
4298 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
4299 APACHE_XLATE builds. [Jeff Trawick]
4301 *) A configuration file parsing problem was fixed. When the
4302 configuration file started with an IfModule/IfDefine container,
4303 only the last statement in the container would be retained.
4306 Changes with Apache 2.0a5
4308 *) Perchild is serving pages after passing them to different child
4309 processes. There are still a lot of bugs, but this does work. I
4310 have made requests against the same installation of Apache, and had
4311 different servers use different user IDs to serve the responses.
4312 This change moves to using socketpair instead of an AF_UNIX socket.
4315 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
4316 It can't seem to pass between child processes yet, but I think we
4317 are closer now than before. This moves us back to using Unix
4318 Domain Sockets. [Ryan Bloom]
4320 *) libapr functions and types renamed with apr_ prefix.
4321 #include "apr_compat.h" for 1.3.x backwards compat
4324 *) Fix problems with APR sockaddr handling on Win32. It didn't always
4325 return the right information on the local socket address.
4326 [Gregory Nicholls <gnicholls@level8.com>]
4328 *) ap_recv() on Win32: Set bytes-read to 0 on error.
4329 [Gregory Nicholls <gnicholls@level8.com>]
4331 *) Add an option to not detach from the controlling terminal without
4332 going into single process mode. This allows for much easier
4333 debugging of the process startup code. [Ryan Bloom]
4335 *) ab: don't use perror() to report the failure of an APR function.
4338 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
4339 scoreboard on graceful restarts.
4342 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
4343 An invalid ap_proc_t was passed to ap_create_process().
4346 *) Allow modules to register filters. Those filters are still
4347 never called, but this is a step in the right direction.
4348 [Ryan Bloom and Greg Stein]
4350 *) Register the mod_cgid daemon process for cleanup so that it is
4351 killed at termination if it does not die when the parent gets
4352 SIGTERM. This change is to fix occasional problems where the
4353 process stays around. Bugs in similar logic in mod_rewrite and
4354 mod_include were also fixed. [Jeff Trawick]
4356 *) Fix a bug in the time handling. Basically, we were imploding a time
4357 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
4358 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
4359 uses those two fields to adjust the time value. Because of the HTTP
4360 spec, both of those values can be zero'ed out safely. This fixes
4361 the bug correctly. [Ryan Bloom]
4363 *) Fix a couple of place in the Windows code where the wrong error
4364 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
4366 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
4368 *) Added the APR_EOL_STR macro for platform dependent differences in
4369 logfiles and other raw text (such as all APR files). Fixes logfiles
4370 not terminated with cr/lf sequences in Win32. [William Rowe]
4372 *) Move all strings functions in APR to src/lib/apr/strings and create
4373 apr_strings.h for the prototypes. [Ryan Bloom]
4375 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
4376 to repeat the syscall until we stop getting EINTR. I noticed a
4377 related problem at termination (SIGTERM) on FreeBSD when using
4378 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
4379 implementation work properly with child init. Previously, ap_lock()
4380 was essentially a no-op because all children were using different
4381 locks and thus nobody ever blocked. [Jeff Trawick]
4383 *) The htdocs/ tree has been moved out of the CVS source tree into
4384 a separate area for easier development. This has NO EFFECT on
4385 end-users or Apache installations. [Ken Coar]
4387 *) Integrate the mod_dav module for WebDAV protocol handling. This
4388 adds the dav and dav_fs modules, the SDBM library, and additional
4389 XML handling utilities. [Greg Stein]
4391 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
4394 *) Update the lib/expat-lite/ library (bring forward changes from
4395 the Apache 1.3 repository). [Greg Stein]
4397 *) If sizeof(long long) == sizeof(long), then prefer long in APR
4398 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
4400 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
4401 machines where sendfile is detected, but nobody has written ap_sendfile.
4402 [Dave Hill <ddhill@zk3.dec.com>]
4404 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
4406 *) ab would start up more connections than needed, then quit when the
4407 desired number were finished. Also fixed a logic error involving
4408 ab keepalives. [Victor J. Orlikowski]
4410 *) WinNT: Implement non-blocking pipes with timeouts to communicate
4411 with CGIs. Apache 2.0a4 had non-blocking pipes but without
4412 timeouts (i.e, if a timeout was specified, the pipe reverted to
4413 a full blocking pipe). Now the behaviour is more in line with
4414 Unix non-blocking pipes.
4417 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
4418 cache open file handles along with accept socket reuse enables
4419 Apache 2.0 to serve non-keepalive requests for static files at
4420 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
4421 and Apache 2.0 will serve almost 1200 rps on my system).
4424 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
4425 supports two config directives, mmapfile (same behavious as
4426 mod_mmap_static) and cachefile. Use the cachefile directive
4427 to cache open file handles. This directive only works on systems
4428 that have implemented the ap_sendfile API. cachefile works today
4429 on Windows NT, but has not been tested on any flavors of Unix.
4432 *) Cleanup the configuration. With the last few changes the
4433 configuration process automatically:
4434 inherits information about how to build from APR. Allowing
4435 APR to inform Apache that it should or should not use -ldl
4437 Detects which mod_cgi should be used mod_cgi or mod_cgid,
4438 based on the threading model
4440 Apache calls APR's configure process before finishing it's
4441 configuration processing, allowing for more information flow
4446 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
4447 with non-zero argument makes the socket non-blocking. BeOS and
4448 OS/2 already worked this way. [Jeff Trawick]
4450 *) ap_close() now calls ap_flush() for buffered files, so write
4451 operations work a whole lot better on buffered files.
4454 *) Fix error messages issued from MPMs which explain where to change
4455 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
4458 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
4459 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
4460 now the way that the blocking state of a pipe is manipulated.
4461 ap_block_pipe() is gone. [Jeff Trawick]
4463 *) Correct the problem where the only local host name that the IP stack
4464 can discover are 'undotted' private names. If no fully qualified
4465 domain name can be identified, the default ServerName will be set to
4466 the machine's IP address string. A warning is always provided if the
4467 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
4469 *) Repair problems with config file processing which caused segfault
4470 at init when virtual hosts were defined and which caused ServerName to
4471 be ignored when there was no valid DNS setup. [Jeff Trawick]
4473 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
4475 *) Add ap_sendfile implementation for AIX
4476 [Victor J. Orlikowski]
4478 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
4479 apr_network_io.h, and apr_thread_proc.h.
4480 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
4482 *) Bring the allocation and pool debugging code back into a working
4483 state. This will need to be tested as so far it's only been used on
4486 *) Change configuration command setup to be properly typesafe when in
4487 maintainer mode. Note that this requires a compiler that can initialise
4488 unions. [Ben Laurie]
4490 *) Turn on buffering for config file reads. Part of this was to
4491 repair buffered I/O support in Unix and implement buffered
4492 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
4494 *) Win32: Fix problem where UTC offset was not being set correctly
4495 in the access log. Problem reported on news group by Jerry Baker.
4498 *) Fix segfault when reporting this type of syntax error:
4499 "</container> without matching <container> section", where
4500 container is VirtualHost or Directory or whatever.
4503 *) SECURITY: CAN-2000-1204 (cve.mitre.org)
4504 Prevent the source code for CGIs from being revealed when
4505 using mod_vhost_alias and the CGI directory is under the document root
4506 and a user makes a request like http://www.example.com//cgi-bin/cgi
4507 as reported in <news:960999105.344321@ernani.logica.co.uk>
4510 *) Add support for the new Beos NetwOrking Environment (BONE)
4513 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
4514 final input char is incomplete; ap_bwrite_xlate() now handles
4515 incomplete final input chars. [Jeff Trawick]
4517 *) Yet another update to saferead/halfduplex stuff -- need to ensure
4518 that a bhalfduplex call occurs before logging or else DNS and
4519 such can delay the last packet of the response. [Dean Gaudet]
4521 *) Some syscall reduction in APR on unix -- don't seek when setting
4522 up an mmap; and don't fcntl() more than once per socket.
4525 *) When mod_cgid is started as root, the cgi daemon now switches
4526 to the configured User/Group (like other httpd processes)
4527 instead of continuing as root. [Jeff Trawick]
4529 *) The prefork MPM now uses an APR lock for the accept() mutex.
4530 It has not been getting a lock at all recently. httpd -V now
4531 displays APR's selection of the lock mechanism instead of the
4532 symbols previously respected by prefork. [Jeff Trawick]
4534 *) Change the mmap() feature test to check only for existence.
4535 The previous check required features not used by Apache.
4538 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
4539 sometimes mangled. The len parm to accept() was not
4540 initialized, leading sometimes to an endless loop of failed
4541 accept() calls on OS/390 and anywhere else that failed the call
4542 if the len was negative. Use <sys/un.h> for struct sockaddr_un
4543 instead of declaring it ourselves to fix a compilation problem
4544 on Solaris. [Jeff Trawick]
4546 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
4548 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
4550 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
4552 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
4553 initialization if ALLOC_DEBUG is defined; no known symptom
4554 otherwise. [Jeff Trawick]
4556 *) Fix typo in configure script when checking for mod_so. bash
4557 doesn't seem to have a problem but /bin/sh on Solaris does.
4558 Symptom: "./configure: test: unknown operator =="
4561 *) Rebind the Win32 NT and 9x services control into the MPM.
4562 All console, WinNT SCM and Win9x pseudo-service control code is
4563 now wrapped within the WinNT MPM.
4566 *) Make a copy of getenv("PATH") before storing for later use. Some
4567 getenv() implementations use the same storage for successive calls.
4568 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
4570 *) Server Tokens work in 2.0 again. This also propogates the change
4571 to allow just the product name in the server string using
4575 Changes with Apache 2.0a4
4577 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
4578 won't need to call it. [Greg Ames, Jeff Trawick]
4580 *) Move pre_config hook call to between configuration read and config
4581 tree walk. This allows all modules to implement pre_config hooks
4582 and know that they will be called at an appropriate time.
4585 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
4588 *) Add pre-config hooks back to all modules.
4591 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
4592 ContentDigest enabled and we can't/don't mmap the file.
4595 *) We now report the correct line number for syntax errors in config
4596 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
4598 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
4599 related bugs, and changed shmem/locking to use apr API. Shared-mem
4600 is currently disabled, however, because of problems with graceful
4601 restarts. [Ronald Tschalär]
4603 *) Fix corruption of IFS variable in --with-module= handling.
4604 Depending on the user's shell or customization thereof, there
4605 would be errors generating ap_config_auto.h later in the configure
4606 procedure. [Jeff Trawick]
4608 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
4609 isn't used (as in 1.3), except that on Unix it is now logged via
4610 ap_log_rerror() instead of by the child having STDERR_FILENO refer
4611 to the error log. [Greg Ames, Jeff Trawick]
4613 *) Add '-D' argument processing for run time configuration defines.
4616 *) Organize http_main.c as independent code, such that no code or
4617 global data is exported from it. WIN32 will dynamically link it
4618 to the server core, so this will prevent mutual dependency.
4621 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
4622 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
4625 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
4626 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
4628 *) Add mod_charset_lite for configuring character set translation.
4631 *) Add '-n' option to htpasswd to make it print its user:pw record
4632 on stdout rather than having to frob a text file. [Ken Coar]
4634 *) Fix saferead. Basically, we flush the output buffer if a read on the
4638 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
4639 a conversion is single-byte only. [Jeff Trawick]
4641 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
4642 the BeOS 5.0 documentation says that shutdown doesn't work yet.
4645 *) Fix some minor errors where pid was being manipulated as an int
4646 instead of the portable pid_t. [Roy Fielding]
4648 *) Fix some error log prints that were printing the pointer to a
4649 structure rather than the pid within the structure.
4650 [Jeff Trawick, Roy Fielding]
4652 *) ab: Fix a command-line processing bug; track bad headers in
4653 err_response; support reading headers up to 2K.
4654 [Ask Bjoern Hansen <ask@valueclick.com>]
4656 *) Fix ap_resolve_env() so that it handles new function added in a prior
4657 alpha (see "Added the capability to do ${ENVVAR} constructs in the
4658 config file.") as well as the constructs used by mod_rewrite.
4659 [Paul Reder <rederpj@raleigh.ibm.com>]
4661 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
4663 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
4664 APR to perform translation, instead of accessing the hard-coded tables
4665 in 1.3's ebcdic.c. [Jeff Trawick]
4667 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
4670 *) Add the ability to hook into the config file reading phase. Basically
4671 if a directive is specified EXEC_ON_READ, then when that directive is
4672 read from the config file, the assocaited function is executed. This
4673 should only be used for those directives that must muck with HOW the
4674 server INTERPRETS the config. This should not be used for directives
4675 that re-order or replace items in the config tree. Those changes should
4676 be made in the pre-config step.
4679 *) Add mod_example to the build system.
4682 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
4683 byte character sets. [Jeff Trawick]
4685 *) Pick up various EBCDIC fixes from 1.3 (from Martin
4686 Kraemer and Oliver Reh originally according to the change log).
4689 *) Fix a couple of problems in RFC1413 support (controlled by the
4690 IdentityCheck directive). Apache did not build the request string
4691 properly and more importantly Apache would loop forever if the
4692 would-be ident server dropped the connection before sending a
4693 properly terminated response. [Jeff Trawick]
4695 *) apxs works in 2.0.
4698 *) Reliable piped logs work in 2.0.
4701 *) Introduce a hash table implementation into APR to be used for
4702 replacing tables and other random data structures in Apache.
4705 *) Add some more error reporting to htpasswd in the case of problems
4706 generating or accessing the temporary file. Also, pass in a
4707 buffer if the implementation knows how to use it (i.e., if L_tmpnam
4708 is defined). [Ken Coar]
4710 *) Configure creates config.nice now containing your configure
4711 options. Syntax: ./config.nice [--more-options]
4714 *) Fix various return code problems in APR on Win32. For most of
4715 these, APR was returning APR_EEXIST instead of GetLastError()/
4716 WSAGetLastError(). [Jeff Trawick]
4718 *) Make piped logs work again in version 2.0
4721 *) Add VPATH support to UNIX build system of Apache and APR.
4724 *) Fix ap_tokenize_to_argv to respect the const arguments that are
4728 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
4729 Patch submitted to author.
4732 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
4733 /sbin in PATH on FreeBSD (all submitted to rse previously)
4736 *) Fix building Pthread-based MPMs on OpenBSD
4737 [Sascha Schumann] PR#26
4739 *) Fix ap_readdir() problem on systems where d_name[] field in
4740 struct dirent is declared with only one byte. (This problem only
4741 affected multithreaded builds.) This caused a segfault during
4742 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
4743 least). [Jeff Trawick]
4745 *) Fix some make-portability problems on at least Tru64, Irix
4747 [Sascha Schumann] PR#18, PR#39
4749 *) Add ap_sigwait() to support old-style sigwait() on systems
4750 like OS/390 and UnixWare.
4753 *) Add POSIX-thread flags for more platforms.
4756 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
4757 (on Unix, at least) to handle resolver errors. Fix a bug in
4758 the definition of APR_ENOMEM so that ap_strerror() can spit
4759 out the correct error message for it.
4762 Changes with Apache 2.0a3
4764 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
4767 *) API: *HOOK* macros now have an AP_ prefix
4770 *) Win32: Eliminate redundant calls to initialize winsock.
4771 [Tim Costello <timcostello@ozemail.com.au>]
4773 *) Fix bugs initializing ungetchar for pipes.
4774 [Chia-liang Kao <clkao@CirX.ORG>]
4776 *) The ab program in the src/support directory is now portable using
4780 *) Support directory is being compiled when the server is built
4783 *) The configure option --with-program-name has been added to allow
4784 developers to rename the executable at configure time. This also
4785 changes the name of the config files to match the executable's name.
4788 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
4789 containing version numbers. [Martin Pool]
4791 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
4792 Unix; access_log and error_log now created with these perms; non-
4793 Unix is unaffected [Jeff Trawick]
4795 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
4796 Replaced more magic numbers with MD5_DIGESTSIZE.
4797 [William Rowe, Roy Fielding]
4799 *) Win32: Get mod_auth_digest compiling and added to the Windows
4800 build environment. Not tested and I'd be suprised if it
4801 actually works. [Bill Stoddard]
4803 *) Revamp the Win32 make environment. Makefiles have been removed and
4804 Apache.dsw created to bring together all the pieces. Create new file
4805 os/win32/BaseAddr.ref to define module base addresses (to prevent
4806 dll relocation at start-up).
4807 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
4809 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
4810 of the \015, \012, and \015\012 constants with macros.
4813 *) Add ap_xlate_open() et al for translation of text between different
4814 character sets. The initial implementation requires iconv().
4817 *) More FAQs and answers from comp.infosystems.www.servers.unix.
4818 [Joshua Slive <slive@finance.commerce.ubc.ca>]
4820 *) CGI output is being timed out now.
4823 *) Fix the problem with dieing quietly. dupfile now takes a pool which
4824 is used by the new apr file. There is no reason to create a new file
4825 with the same lifetime as the original file.
4828 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
4829 module base addresses. This will help shooting seg faults
4830 in the field. [William Rowe <wrowe@lnd.com>]
4832 *) Update Apache on Windows documentation. Add new document
4833 describing how to compile Apache on Windows.
4834 [William Rowe <wrowe@lnd.com>]
4836 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
4837 microseconds instead of seconds. Some storage leaks and other
4838 minor bugs in related code were fixed. [Jeff Trawick]
4840 *) Win32: First cut at getting mod_isapi working under 2.0
4841 [William Rowe <wrowe@lnd.com>]
4843 *) First stab at getting mod_auth_digest working under 2.0
4844 quick change summary:
4845 - moved the random byte generation (ap_generate_random_bytes) into APR
4846 - now uses ap_time_t
4847 - compiles and runs on linux
4849 [Brian Martin <bmartin@penguincomputing.com>]
4851 *) Win32: Move the space stripping of physical service names
4852 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
4853 unresolved symbol. Add dependency checking to the
4854 CreateService call to ensure TCPIP and AFP (winsock) is started
4856 [William Rowe <wrowe@lnd.com>]
4858 *) Win32: Add code to perform latebinding on functions that may
4859 not exist on all levels of Windows where Apache runs. This
4860 is needed to allow Apache to start-up on Win95/98. All calls
4861 to non portable functions should be protected with
4862 ap_oslevel checks to prevent runtime segfaults.
4863 [William Rowe <wrowe@lnd.com>]
4865 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
4867 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
4869 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
4870 This addresses PR 1623. Still need to address timing out runaway
4871 CGI scripts. [Bill Stoddard]
4873 *) Win32: Make ap_stat Windows 95/98 friendly
4874 [William Rowe <wrowe@lnd.com>]
4876 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
4877 always fail. Need to initialise the dwOSVersionInfoSize member of the
4878 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
4881 The patch also enhances ap_get_oslevel (and the associated enum) to
4882 handle selected service packs for NT4, and adds recognition for
4883 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
4884 we can use ReadFileScatter and WriteFileGather in readwrite.c.
4885 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
4887 *) Get mod_rewrite building and running, and mod_status building for Win NT
4888 [Allan Edwards <ake@raleigh.ibm.com>]
4890 *) Patch to port mod_auth_db to the 2.0 api and also to support
4891 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
4892 2.7.7. It should work with version 1 as well but I haven't tested it.
4893 [Brian Martin <bmartin@penguincomputing.com>]
4895 *) Get APR DSO code working under Windows. Includes cross platform
4897 [Tim.Costello@BTFinancialgroup.com]
4899 *) Fix some of the Windows APR time functions.
4902 *) FAQ changes related to tidying up historical documents on the web site.
4903 [Joshua Slive <slive@finance.commerce.ubc.ca>]
4905 *) Move Windows DSO code into APR.
4908 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
4909 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
4910 at build time. At this point, the server will not compile on Windows because
4911 of the recent DSO commits. Fixing those next.
4912 [Bill Rowe & Bill Stoddard]
4914 *) Added error checking for file I/O APR routines.
4915 [Jon Travis <jtravis@covalent.net>]
4917 *) APR: Don't use the values of resolver error codes for the
4918 corresponding APR error codes. On Unix and Win32, return the
4919 proper APR error code after a resolver error. [Jeff Trawick]
4921 Changes with Apache 2.0a2
4923 *) Renamed the executable back to httpd on all platforms other
4927 *) Allow BeOS to survive restarts, log properly and a few
4928 small things it had problems with due to the way it setup
4929 users and groups. [David Reid]
4931 *) Get mod_rewrite working with APR locks
4932 [Paul Reder <rederpj@raleigh.ibm.com>]
4934 *) Actually remove the sempahore when the lock cleanup routine
4935 is called on BeOS. [David Reid]
4937 *) Clear hook registrations between reads of the config file.
4938 When DSOs are unloaded and re-loaded the old hook pointers may
4939 no longer be valid. This fix eliminates potential segfaults.
4940 [Allan Edwards <ake@raleigh.ibm.com>]
4942 *) Fix a problem with Sigfunc not being defined or bypassed
4943 if sigaction() wasn't found. [Jim Jagielski]
4945 *) Fix the locking mechanism on BSD variants. They now use fcntl
4946 locks. This allows the server to start and serve pages.
4949 *) First cut at getting the Win32 installer to work
4950 [William Rowe <wrowe@lnd.com>]
4952 *) Get htpasswd compiling under Windows
4953 [William Rowe <wrowe@lnd.com>]
4955 *) Change the log message for a bind() failure to show the
4956 interface and port number. [Jeff Trawick]
4958 *) Import the documentation from 1.3.12 and bring parts of it
4959 up-to-date with respect to the changes that have occurred
4963 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
4964 now logged correctly on BeOS.
4967 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
4968 Makefile.win includes the same user interface as the old
4970 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
4972 *) Win32 exec now uses COMSPEC environment string for command
4973 shell path resolution.
4974 [William Rowe <wrowe@lnd.com>] PR#3715
4976 *) Win32: ap_connect() was not returning correct error condition
4978 [Allen Prescott <allen@clanprescott.com>]
4980 *) Win32: ap_open() was broken on Win9x because an NT-specific
4981 flag was passed to CreateFile. ap_puts() added an unnecessary
4983 [Jeff Trawick <trawick@us.ibm.com>]
4985 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
4986 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
4987 confusing ee/et name and made all extensions language/dialect
4988 rather than country reflecting. Changed example files to
4989 explicit reflect the ISO charset and added a few common
4990 ones to the example config [dirkx]
4992 *) Extend external module capability. To use this, you call
4993 configure with --with-module=path/to/mod1,path/to/mod2,etc.
4996 *) Backported the various "default charset" fixes from 1.3.12,
4997 including the AddDefaultCharset directive. [Jim Jagielski]
4999 *) Added the capability to do ${ENVVAR} constructs in the
5000 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
5001 it does this on a line by line basis; i.e. if the envvar
5002 expands to something with spaces you have to protect it
5003 by adding quotes around it (Unless of course you expect it
5004 to contains more than one argument. Alternatively you
5005 can compile it on a per token basis; which is what people
5006 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
5007 hampers fancier hacks.
5008 [Dirk-Willem van Gulik]
5010 *) Changed the 'ErrorDocument' syntax in that it NO longer
5011 supports the asymetric
5013 ErrorDocument 301 "Some message
5015 Note the opening " quote, without a closing quote. It now
5016 has either the following syntaxes
5018 ErrorDocument XXX /local/uri
5019 ErrorDocument XXX http://valid/url
5020 ErrorDocument XXX "Some Message"
5022 The recognition heuristic is: if it has a space it
5023 is a message. If it has no spaces and starts with a /
5024 or is a valid URL then treat it that way. Otherwise it
5025 is assumed to be a message.
5027 This breaks backward compatibility but makes live a hell
5028 of a lot easier for GUI's and config file parsers.
5029 [Dirk-Willem van Gulik]
5031 *) Changed 'CacheNegotiatedDocs' from its present/not-present
5032 syntax into a 'on' or 'off' syntax. As it currently is the
5033 only non nesting token which uses NO_ARGS and thus is an
5034 absolute pain for any config interface automation. This
5035 breaks backward compatibility. [Dirk-Willem van Gulik]
5037 *) Add ability to add external modules to the build process. This is
5038 done with --with-module=/path/to/module. Modules can only be added
5039 as static modules at this point.
5042 Changes with Apache 2.0a1
5044 *) Fix FreeBSD 3.3 core dump.
5045 Basically, ap_initialize() needs to get called before
5046 create_process(), since create_process() passes op_on structure
5047 to semop() to get a lock, but op_on isn't initialized until
5048 ap_initialize() calls setup_lock(). Here is a slight
5049 rearrangement to main() which calls ap_initialize() earlier...
5050 [Jeff Trawick <trawick@us.ibm.com>]
5052 *) Enable Apache to use sendfile/TransmitFile API
5053 [Bill Stoddard, David Reid, Paul Reder]
5055 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
5059 *) Make file I/O and network I/O writev/sendv APIs consistent.
5060 Eliminate use of ap_iovec_t and use Posix struct iovec.
5061 Use seperate variable on ap_writev to set the number of iovecs
5062 passed in and number of bytes written.
5065 *) Adapt file iol to use APR functions. Replaced ap_open_file()
5066 with ap_create_file_iol(). ap_create_file_iol() requires that
5067 the file be opened prior to the call using ap_open().
5070 *) Port mod_include and mod_cgi to 2.0
5071 [Paul Reder, Bill Stoddard]
5073 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
5074 bytes_read/bytes_written is always valid (never -1). Plus
5075 some fixes to buff.c to correct problems introduced by the
5076 errno => ap_status_t changes a while back. Plus a fix to
5077 chunked encoding introduced right at the beginning of 2.0.
5080 *) Revamped UNIX build system to use autoconf and libtool.
5081 [Manoj Kasichainula, Sascha Schumann]
5083 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
5085 *) SECURITY: More rigorous checking of Host: headers to fix security
5086 problems with mass name-based virtual hosting (whether using mod_rewrite
5087 or mod_vhost_alias).
5088 [Ben Hyde, Tony Finch]
5090 *) Add back support for UseCanonicalName in <Directory> containers.
5091 [Manoj Kasichainula]
5093 *) Added APLOG_STARTUP log type. This allows us to write an error
5094 message without any of the date and time information. As a part
5095 of this change, I also removed all of the calls to fprintf(stderr
5096 and replaced them with calls to ap_log_error using APLOG_STARTUP
5097 writing to stderr is no longer portable, because we don't direct
5098 stderr to the error log on all platforms.
5101 *) Convert error logging functions to take errno as an argument.
5102 This makes our error logs more portable, because some Windows API's
5103 don't set errno. This change allows us to still output a valid
5104 message on all of our platforms.
5107 *) mod_mime_magic runs in 2.0-dev now.
5108 [Paul Reder <rederpj@raleigh.ibm.com>]
5110 *) sendfile has been added to APR.
5111 [John Zedlewski <zedlwski@Princeton.EDU>]
5113 *) buff.c has been converted to no longer use errno.
5114 [Manoj Kasichainula]
5116 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
5117 interface adaption to APR functions did it. [Martin Kraemer]
5119 *) Support DSOs properly on 32-bit HP-UX 11.0
5120 [Dilip Khandekar <dilip@cup.hp.com>]
5122 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
5123 [Ralf S. Engelschall]
5125 *) Cleaned APR build environment integration and bootstrap APR
5126 automatically for developers from src/Configure.
5127 [Ralf S. Engelschall]
5129 *) Fixed building of src/support/htpasswd.c
5130 [Ralf S. Engelschall]
5132 *) When generating the Location: header, mod_speling forgot
5133 to escape the spelling-fixed uri. (Forw-Port from 1.3)
5136 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
5138 *) Change all pools to APR contexts. This is the first step to
5139 incorporating APR into Apache. [Ryan Bloom]
5141 *) Move "handler not found" warning message to below the check
5142 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
5143 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
5145 *) Support line-continuation feature in config.option file and
5146 allow the loading of multiple option sections at once via
5147 ``--with-option=<section1>,<section2>,...''
5148 [Ralf S. Engelschall]
5150 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
5152 Changes with Apache MPM
5154 *) Use asynchronous AcceptEx() and a completion port to accept and
5155 dispatch connections to threads in Windows NT/2000.
5158 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
5161 *) Implement the APACI --with-option facility
5162 (per default used the config.option file).
5163 [Ralf S. Engelschall]
5165 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
5167 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
5168 Replace pre_connection module call with a register_hook call and
5169 implement pre_connection as a hook. The intent is that these hooks will
5170 be extended to allow Apache to be multi-protocol, and also to allow the
5171 calling order to be specified on a per-hook/per-module basis.
5174 *) Implement mpm_* methods as "modules". Each method gets its own
5175 subdir in src/modules (eg: src/modules/prefork). Selection
5176 of method uses Rule MPM_METHOD. [Jim Jagielski]
5178 *) Port the hybrid server from the apache-apr repository as
5179 mpm_mpmt_pthread. [Manoj Kasichainula]
5181 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
5182 amongst the unix MPMs.
5184 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
5185 signal handling for the new world order. [Dean Gaudet]
5187 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
5188 of alloc.c for now. [Dean Gaudet]
5190 *) Handle partial large writes correctly. [Ben Laurie]
5192 *) Eliminate conn_rec's pointer to server. All it knows is the base server
5193 based on IP/port. [Ben Laurie]
5195 *) Port a bunch of modules to the new module structure.
5196 ["Michael H. Voase" <mvoase@midcoast.com.au>]
5198 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
5200 *) Basic restructuring to introduce the MPM concept; includes various
5201 changes to the module API... better described by
5202 docs/initial_blurb.txt. [Dean Gaudet]
5204 Changes with Apache pthreads
5206 *) New buff option added: BO_TIMEOUT. It describes the timeout for
5207 buff operations (generally over a network).
5208 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
5210 *) Created http_accept abstraction. Added 4 new functions (not exported):
5211 init_accept(), begin_accepting_requests(), get_request(),
5212 stop_accepting_requests() [Bill Stoddard]
5214 *) Fix to ap_rprintf call that allows mod_info to work properly.
5215 [James Morris <jmorris@intercode.com.au>]
5217 *) user and ap_auth_type fields were moved from connection_rec to
5218 request_rec. [Ryan Bloom]
5220 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
5221 needed in a threaded server.
5223 *) Initial pthread implementation from from Dean's apache-nspr code.
5224 [Bill Stoddard, Ryan Bloom]
5227 Changes with Apache 1.3.9
5229 *) Remove bogus error message when a redirect doesn't set Location.
5230 Instead, use an empty string to avoid coredump if the error message
5231 was supposed to include a location. [Roy Fielding]
5233 *) Don't allow configure to include mod_auth_digest unless it is
5234 explicitly requested, even if the user asked for all modules.
5237 *) Translate module names to dll names for OS/2 so that they are no more
5238 than 8 characters long and have an extension of "dll" instead of "so".
5241 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
5242 Fix test-compile check to check for randbyte instead of trand32.
5243 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
5244 and tweak to make Amaya happier. [Ronald Tschalär]
5246 *) Ensure that the installed expat include files are world readable,
5247 just like the other header files. [Martin Kraemer]
5249 *) Fixed generated AddModule adjustments in APACI's `configure' script
5250 in order to allow (new) modules like mod_vhost_alias to be handled
5251 correctly (which was touched by the adjustments for mod_alias).
5252 [Ralf S. Engelschall]
5254 *) For binary builds, add -R flag to apachectl to work around the lack of
5255 an absolute path to the ./libexec directory where the libhttp.ep file
5256 is needed for SHARED_CORE architectures. [Randy Terbush]
5258 *) WIN32: Create the CGI script process as DETACHED. This may solve the
5259 problem observed by some Win95/98 users where they get CGI script
5260 output sent to the console. [Bill Stoddard]
5262 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
5263 routines are now called ap_base64* and are 'plain' (i.e., no
5264 pool access or anything clever). Inside util.c the routines acting
5265 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
5266 The oddly named ap_uuencode(), ap_uudecode() are kept around for
5267 now but deprecated. [dirkx]
5269 *) Clean up the base64 and SHA1 additions and make sure they are
5270 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
5271 files. [Roy Fielding]
5273 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
5274 checking. Allow compiling on VS 6.0. [Randy Terbush]
5276 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
5278 *) Use TestCompile to search for the truerand library (rather than blindly
5279 assuming its existence). If it is not found, complain (but do not
5280 exit - yet). [Martin Kraemer]
5282 *) We forgot to add the new exported function names to
5283 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
5285 *) Add description of -T command-line option to usage().
5286 [Ralf S. Engelschall]
5288 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
5289 searched only AFTER libap has been searched, because libap needs
5290 some symbols from libos. [Martin Kraemer]
5292 *) Fix conflict with original mod_digest related to the symbol of the
5293 module dispatch list (which has to be unique for DSO and follow the
5294 usual conventions for the installation procedure).
5295 [Ralf S. Engelschall]
5297 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
5298 for other platforms as well. [Martin Kraemer]
5300 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
5301 types by AP_LONG and replace reference to renamed variable 'ubuf'
5302 by 'buffer'. [Martin Kraemer]
5304 Changes with Apache 1.3.8 [not released]
5306 *) Flush the output buffer immediately after sending an error or redirect
5307 response, since the result may be needed by the client to abort a
5308 long data transfer or restart a series of pipelined requests.
5309 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
5311 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
5312 [Ian Turner <iant@sequent.com>] PR#4735
5314 *) Local struct mmap in http_core.c conflicted with system structure
5315 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
5317 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
5318 [Ronald Tschalär <ronald@innovation.ch>]
5320 *) Fix a memory leak where the module counts were getting messed
5321 up across restarts. [David Harris <dharris@drh.net>]
5323 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
5324 properly in mod_access.
5325 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
5327 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
5328 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
5330 *) PORT: Support for compaq/tandem/com.
5331 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
5333 *) Added SHA1 password encryption support to easy migration from
5334 Netscape servers. See support/SHA1 for more information.
5335 Caused the separation of ap_md5.c into md5, sha1 and a general
5336 ap_checkpass.c with just a validate_passwd routine. Added a
5337 couple of flags to support/htpasswd. Some reuse of the to64()
5338 function; hence renamed to ap_to64().
5339 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
5341 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
5342 with ASCII/EBCDIC conversions in "ident" query.
5343 [David McCreedy <McCreedy@us.ibm.com>]
5345 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
5346 Change "Power Macintosh" to Power* so if uname prints "Power Book"
5347 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
5349 *) Fix SIGSEGV on some systems because the Vary fix below included
5350 a call to table_do with a variable argument list that was not
5351 NULL terminated. Replaced with better implementation. [Roy Fielding]
5353 Changes with Apache 1.3.7 [not released]
5355 *) The "Vary" response header field is now sanitised right before
5356 the header is sent back to the client. Multiple "Vary" fields
5357 are combined, and duplicate tokens (e.g., "Vary: host, host" or
5358 "Vary: host, negotiate, host, accept-language") are reduced to
5359 single instances. This is a better solution than the force-no-vary
5360 one (which is still valid for clients that can't cope with Vary
5361 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
5363 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
5365 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
5366 least on Linux and FreeBSD for now.
5369 *) Win32: More apache -k restart work. Restarts are now honored
5370 immediately and connections in the listen queue are -not- lost.
5371 This is made possible by the use of the WSADuplicateSocket()
5372 call. The listeners are opened in the parent, duplicated, then
5373 the duplicates are passed to the child. The original listen sockets
5374 are not closed by the parent across a restart, thus the listen queue
5376 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5378 *) Fix handling of case when a client has sent "Expect: 100-continue"
5379 and we are going to respond with an error, but get stuck waiting to
5380 discard the body in the pointless hope of preserving the connection.
5381 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
5383 *) Fix 'configure' to work correctly with SysV-based versions of
5384 'tr' (consistent with Configure's use as well). [Jim Jagielski]
5386 *) apxs: Add "-S var=val" option which allows for override of CFG_*
5387 built-in values. Add "-e" option which works like -i but doesn't
5388 install the DSO; useful for editing httpd.conf with apxs. Fix
5389 editing code so that multiple invocations of apxs -a will not
5390 create duplicate LoadModule/AddModule entries; apxs can now be
5391 used to re- enable/disable a module. [Wilfredo Sanchez]
5393 *) Win32: Update the server to use Winsock 2. Specifically, link with
5394 ws2_32.lib rather than wsock32.lib. This gives us access to
5395 WSADuplcateSocket() in addition to some other enhanced comm APIs.
5396 Win 95 users may need to update their TCP/IP stack to pick up
5397 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
5398 [Bill Stoddard stoddard@raleigh.ibm.com]
5400 *) Win32: Redirect CGI script stderr (script debug info) into the
5401 error.log when CGI scripts fail. This makes Apache on Win32
5402 behave more like Unix.
5403 [Bill Stoddard stoddard@raleigh.ibm.com]
5405 *) Fixed `httpd' usage display: -D was missing.
5406 [Ralf S. Engelschall] PR#4614
5408 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
5409 [Ralf S. Engelschall] PR#4561, PR#4562
5411 *) OS/2: Fix problem with accept lock semaphores where server would die with
5412 "OS2SEM: Error 105 getting accept lock. Exiting!"
5413 [Brian Havard] PR#4505
5415 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
5416 [Randy Terbush <randy@covalent.net>]
5418 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
5419 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
5421 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
5422 command potentially _is_ GCC. [Ralf S. Engelschall]
5424 *) Fix apxs build issues on AIX
5425 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
5427 *) DocumentRoot Checking: Under previous versions, when Apache
5428 first started up, it used to do a stat of each DocumentRoot to
5429 see if it existed and was a directory. If not, then an error
5430 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
5431 does not exist, you will get error messages in error_log. If
5432 the '-t' command line option is used (to check the configuration)
5433 the check of DocumentRoot IS performed. An additional command
5434 line option, '-T', has been added if you want to avoid the
5435 DocumentRoot check even when checking the configuration.
5438 *) Win32: The query switch "apache -S" didn't exit after showing the
5439 vhost settings. That was inconsistent with the other query functions.
5440 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
5442 *) Win32: Changed behaviour of apache -k restart.
5443 Previously, the server would drain all connections in the stack's
5444 listen queue before honoring the restart. On a busy server, this
5445 could take hours. Now, a restart is honored almost immediately.
5446 All connections in Apache's queues are handled but connections in
5447 the stack's listen queue are discarded. Restart triggered by
5448 MaxRequestPerChild is unchanged.
5449 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5451 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
5452 the accept loop. Good for a 5% performance boost. Cleaned up
5453 parent/child process management code.
5454 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5456 *) Added ceiling on file size for memory mapped files.
5457 [John Giannandrea <jg@meer.net>] PR#4122
5459 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
5460 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
5461 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
5463 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
5464 use this at least for Expat. [Ralf S. Engelschall]
5466 *) Allow .module files to specify libraries with Lib:.
5469 *) Allow SetEnvIf[NoCase] to test environment variables as well
5470 as header fields and request attributes. [Ken Coar]
5472 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
5473 content-types are "text/html;parameters". PR#4524 [Ken Coar]
5475 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
5476 never accepted into any standard, and it opens up certain DoS
5477 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
5479 *) TestCompile updated. We can now run programs and output the
5480 results during the Configure process. [ Jim Jagielski]
5482 *) The source is now quad (long long) aware as needed. Specifically,
5483 the Configure process determines the correct size of off_t and
5484 *void. When the OS/platform/compiler supports quads, ap_snprintf()
5485 provides for the 'q' format qualifier (if quads are not available,
5486 'q' is silently "demoted" to long). [Jim Jagielski]
5488 *) When the username or password fed to htpasswd is too long, include the
5489 size limit in the error message. Also report illegal characters
5490 (currently only ':') in the username. Add the size restrictions
5491 to the man page. [Ken Coar]
5493 *) Fixed the configure --without-support option so it doesn't result in
5494 an infinite loop. [Marc Slemko]
5496 *) Piped error logs could cause a segfault if an error occured
5497 during configuration after a restart.
5498 [Aidan Cully <aidan@panix.com>] PR#4456
5500 *) If a "Location" field was stored in r->err_headers_out rather
5501 than r->headers_out, redirect processing wouldn't find it and
5502 the server would core dump on ap_escape_html(NULL). Check both
5503 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
5504 if Location isn't set. [Doug MacEachern, Ken Coar]
5506 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
5507 of the Expat 1.0.2 distribution. [Greg Stein]
5509 *) Replace regexec() calls with calls to a new API stub function
5510 ap_regexec(). This solves problems with DSO modules which use the regex
5511 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
5513 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
5514 environment variables can be set according to the protocol version
5515 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
5517 *) Add DSO support for OpenStep (Mach 4.2) platform.
5518 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
5520 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
5521 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
5523 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
5524 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
5526 *) Better DSO flags recognition on NetBSD platforms using ELF.
5527 [Todd Vierling <tv@pobox.com>] PR#4310
5529 *) Always log months in english format for %t in mod_log_config.
5530 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
5532 *) Support for server-parsed and multiview-determined ReadmeName and
5533 HeaderName files in mod_autoindex. Removed the restriction on
5534 "/"s in ReadmeName and HeaderName directives since the *sub_req*
5535 routines will deal with the access issues. (It's now possible to
5536 have {site|group|project|customer|...} wide readmes and headers.)
5537 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
5540 *) When stat() fails, don't assume anything about the contents of
5541 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
5543 *) It's OK for a semop to return EINTR, just loop around and try
5544 again. [Dean Gaudet]
5546 *) Fix configuration engine re-entrant hangups, which solve a
5547 handful of problems seen with mod_perl <Perl> configuration sections
5548 [Salvador Ortiz Garcia <sog@msg.com.mx>]
5550 *) Mac OS and Mac OS X Server now use the appropriate custom layout
5551 by default when building with APACI; allow for platform-specific
5552 variable defaults in configure. [Wilfredo Sanchez]
5554 *) Do setgid() before initgroups() in http_main; some platforms
5555 zap the grouplist when setgid() is called. This was fixed in
5556 suexec earlier, but the main httpd code missed the change.
5557 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
5559 *) Add recognition of .tgz as a gzipped tarchive.
5560 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
5562 *) mod_include's fsize/flastmod should allow only relative paths, just
5563 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
5565 *) OS/2: Add support for building loadable modules using DLLs.
5568 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
5571 *) Fix minor but annoying bug with the test for Configuration.tmpl
5572 being newer than Configuration so that it is less likely to fail
5573 when using APACI and shadow sources. [Wilfredo Sanchez]
5575 *) PORT: Add initial support for Mac OS (versions 10.0 and
5576 greater). Use Mac OS X Server layout for now. Clean up dyld code
5577 in unix/os.c, and don't install the dyld error handlers, which
5578 are no longer needed in Mac OS. [Wilfredo Sanchez]
5580 *) Rename Rhapsody layout to "Mac OS X Server". Change install
5581 locations to appropriate ones for user-built (as opposed to
5582 system) installs. [Wilfredo Sanchez]
5584 *) Modify mod_autoindex's handling of AddDescription so that the
5585 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
5587 *) Add functionality to the install-bindist.sh script created by
5588 binbuild.sh to use tar when copying distribution files to the
5589 serverroot. This allows upgrading an existing installation
5590 without nesting the new distribution in the old.
5592 install-bindist.sh now detects the local perl5 path to install
5593 apxs and dbmmanage with proper path to perl interpreter.
5595 Add an install-binsupport target which copies the source files
5596 for apxs and dbmmanage to bindist to allow these scripts to
5597 be properly installed relative to the destination serverroot.
5598 [Randy Terbush, Covalent Technologies, randy@covalent.net]
5600 *) Fix intermittent SEGV in ap_proxy_cache_error() in

5612 *) Force the LANG envariable to the known state of "C" so that we
5613 have assurance about how string manipulators (e.g., tr) will
5614 function. [Ken Coar] PR#1630
5616 *) Add a directive to allow customising of the tracking cookie name.
5617 [Ken Coar] PR#2921, 4303
5619 *) Add "force-no-vary" envariable to allow servers to work around
5620 clients that choke on "Vary" fields in the response header.
5621 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
5623 *) Fixed a bug in mod_dir that causes a child process will infinitely
5624 recurse when it attemps to handle a request for a directory wnd the
5625 value of the DirectoryIndex directive is a single dot. Also likely
5626 to happen for anyother values of DirectoryIndex that will map back
5627 to the same directory. The handler now only considers regular files
5628 as being index candidates. No PR#s found.

5667 *) APACI would not correctly build suexec. [Maria Verina
5668 <mariav@icgeb.trieste.it>] PR#4260
5670 *) mod_mime_magic passed only the first 4k of a file to
5671 uncompress/gzip, but those tools sometimes do not produce
5672 any output unless a sufficient portion of the compressed
5673 file is input. Change to pass the entire file -- but
5674 only read 4k of output.

5681 redirects. [Jose KAHAN <kahan@w3.org>] PR#3910, 3806, 3575
5683 *) When padding the name with spaces for display, mod_autoindex would

5704 *) Prevent clobbering saved IFS values in APACI. [Jim Jagielski]
5706 *) Fix buffer overflows in ap_uuencode and ap_uudecode pointed out
5707 by "Peter 'Luna' Altberg <peter@altberg.nu>" and PR#3422
5708 [Peter 'Luna' Altberg <peter@altberg.nu>, Ronald Tschalär]
5710 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
5713 *) Correct an apparent typo: on the Windows and MPE platforms, the
5714 htpasswd utility was limiting passwords to only 8 characters.
5717 *) EBCDIC platforms: David submitted patches for two bugs in the
5718 MD5 digest port for EBCDIC machines:
5719 a) the htdigest utility overwrote the old contents of the digest file
5720 b) the Content-MD5 header value (ContentDigest directive) was wrong
5721 when the returned file was not converted from EBCDIC, but was a
5722 binary (e.g., image file) in the first place.
5723 [David McCreedy <mccreedy@us.ibm.com>]
5725 *) support/htpasswd now permits the password to be specified on the
5726 command line with the '-b' switch. This is useful when passwords
5727 need to be maintained by scripts -- particularly in the Win32
5728 environment. [Ken Coar]
5730 *) Win32: Win32 multiple services patch. Added capability to install and
5731 run multiple copies of apache as individual services.
5734 apache -n apache1 -i -f c:/httpd.conf
5735 Installs apache as service 'apache1' and associates c:/httpd.conf
5738 Starts apache1 service.
5740 Stops apache1 service
5743 apache -n apache2 -i
5744 Installs apache as service 'apache2'. httpd.conf is located under
5745 the default server root (/apache/conf/httpd.conf).
5747 Starts apache2 service.
5750 apache -n apache3 -i -d c:/program files/apache
5751 Install apache as service 'apache3' and sets server root to
5752 c:/program files/apache.
5755 apache -n apache2 -k restart
5756 Restart apache2 service
5758 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
5760 *) Correct the signed/unsigned character handling for the MD5 routines;
5761 mismatches were causing compilation problems with gcc -pedantic and
5762 in the TPF cross-compilation. [Ken Coar]
5764 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
5765 a roughly 5 fold speed up. [Brian Havard]
5767 *) proxy ftp: instead of using the hardwired string "text/plain" as
5768 a fallback type for files served by the ftp proxy, use the
5769 ap_default_type() function to determine the configured type.
5770 This allows for special configurations like
5771 <Directory proxy:ftp://some.host>
5772 DefaultType gargle/blurb
5774 Additionally, add the Content-Encoding: header to FTP proxy replies
5775 when the encoding is defined (by the AddEncoding directive).
5776 Because it was missing, it was almost impossible to browse compressed
5777 files using the FTP proxy (works now perfectly in Communicator).
5778 The ftp proxy now also returns the Date: and Server: header lines (if not
5779 much else... This code is "somewhat" broken) like normal requests do.
5782 *) Be more smart in APACI's configure script when determining the UID/GID
5783 for User/Group directives and use the determined UID/GID to initialize
5784 the permissions on the proxycachedir.
5785 [Dirk-Willem van Gulik, Ralf S. Engelschall]
5787 *) Changed the forking-prior-to-cleanup in the proxy module to first
5788 check wether it actually needs to collect garbage. This reduces
5789 the number of fork()s from one/request to just the odd one an hour.
5790 [Dirk-Willem van Gulik]
5792 *) Added proxy, auth and header support to src/support/ab.c. Added a
5793 README file to src/support/

5799 *) Add support for DSO module compilation on BSD/OS 3.x.
5800 [Randy Terbush, Covalent Technologies]
5802 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
5803 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
5804 option) were substituted with $(TARGET).conf, etc. Same for other strings
5805 with dots where the dot wasn't matched as plain text.

5813 Changes with Apache 1.3.6
5815 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
5817 Changes with Apache 1.3.5 [not released]
5819 *) M_INVALID needed a value within the scope of METHODS so that unknown
5820 methods can be access controlled. [Roy Fielding] PR#3821
5822 *) Added PassAllEnv; makes server's entire environment available
5823 to CGIs and SSIs executed within directive's scope. [Ken Coar]
5825 *) ap_uuencode() always added two trailing '='s and encoding of
5826 8 bit characters on a machine with signed char may produced
5827 incorrect results. Additionally ap_uuencode() should now
5828 work correctly on EBCDIC platforms.
5829 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
5831 *) WIN32: Binary installer now runs the configuration DLL before
5832 the reboot prompt (which is only given if MSVCRT.DLL system
5833 DLL is new or updated). This should avoid the configuration
5834 directory being empty after installation. [Paul Sutton]
5835 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
5837 *) WIN32: Binary installer now creates Start menu options to start
5838 and stop Apache as a console application and to uninstall
5839 the Apache service on NT. [Paul Sutton] PR#3741
5841 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
5843 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
5844 have been reported with flock() locking (probably related to kernel
5845 version). [Dean Gaudet] PR#2723, 3531
5847 *) Using APACI, the main config file (usually httpd.conf) was
5848 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
5849 <wsanchez@apple.com>]
5851 *) PORT: AIX does not require the SHARED_CODE "hack"
5852 [Ryan Bloom <rbb@raleigh.ibm.com>]
5854 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
5855 avoidance code added in 1.3.3.
5856 [Dean Gaudet, Jeff Lewis <lewis@stanford.edu>] PR#3872
5858 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
5859 for 8-bit safeness. [Dean Gaudet]
5861 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
5862 because SPARCs have a small machine-specific maximum size for the Global
5863 Offset Table which is often exceeded when compiling one of the larger
5864 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
5866 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
5867 DSO/DLL section because it's a directive from mod_status and isn't
5868 available before the DLL of mod_status is loaded.
5869 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
5871 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
5872 continuation facility in Apache's configuration files which could
5873 lead to a buffer overflow situation.
5874 [Thomas Devanneaux <Thomas.Devanneaux@enst.fr>] PR#3617

5880 really support all future gcc versions >= 2.7 until we know more.
5881 [John Tobey <jtobey@banta-im.com>] PR#3983
5883 *) Let APACI's configure script correctly complain for unknown --enable-XXX
5884 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
5886 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
5887 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
5888 possible buffer overflows. [Ralf S. Engelschall]
5890 *) Remove no longer used non-API function ap_single_module_init().
5891 [Ralf S. Engelschall]
5893 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
5896 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
5897 to make platform installations easier. [Wilfredo Sanchez]
5899 *) In configure, do not append the target name to the directory path if
5900 the path already contains "apache". [Ralf S. Engelschall]
5902 *) SIGPIPE is now ignored by the server core. The request write routines
5903 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
5904 correctly check for output errors and mark the connection as aborted.
5905 Replaced many direct (unchecked) calls to ap_b* routines with the
5906 analogous ap_r* calls. [Roy Fielding]
5908 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
5909 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
5910 Furthermore map lookups for non-existent keys are now cached as well.
5911 Additionally "txt" maps are now parsed with simple string functions
5912 instead of using ap_pregcomp(). As a side effect a bug that prevented
5913 the usage of keys containing the "," character was fixed.
5914 The changes drastically improve the performance when large rewrite maps
5916 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
5918 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
5919 other than GET, and const'd the definition of method in request_rec.
5922 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
5924 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
5925 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
5927 *) Add %V to mod_log_config, this logs the hostname according to the
5928 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
5929 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
5931 *) Add support for \n and \t to mod_log_config, can be used to produce
5932 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
5934 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
5936 *) Added informative error messages for failed munmap() and fseek() calls
5937 in http_core.c. [John Bley, Roy Fielding]
5939 *) Added some informative error messages for some failed malloc()
5940 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
5942 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
5943 is removed. This allows <Directory proxy:*> directives to work and
5944 prevents invalid requests from killing the process.
5945 [Brian Havard <brianh@kheldar.apana.org.au>]
5947 *) Reorganised FAQ document.
5948 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
5950 *) src/support/: The ApacheBench benchmark program was overhauled by
5951 David N. Welton: you can now have it generate an HTML TABLE, presumably
5952 for integration into other HTML sources. David updated the ab man page
5953 as well and added some missing descriptions. Thanks!
5954 [David N. Welton <davidw@prosa.it>]
5956 *) Win32: The filename validity checker now allows filenames containing
5957 characters in the range 0x80 to 0xff (for example accented characters).
5958 [Paul Sutton] PR#3890
5960 *) Added conditional logging based upon environment variables to
5961 mod_log_config. mod_log_referer and mod_log_agent
5962 are now deprecated. [Ken Coar]
5964 *) Allow apache acting as a proxy server to relay the real
5965 reason of a failure to a client rather than the "internal
5966 server error" it does currently. The general exposure mechanism
5967 can be triggered by any module by setting the "verbose-error-to"
5968 note to "*"; this allows more than just proxy errors to be exposed.
5969 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
5971 *) Moved man pages for ab and apachectrl to section 8.
5972 [Wilfredo Sanchez, Roy Fielding]
5974 *) Added -S option to install.sh so that options can be passed to
5975 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
5977 *) Tweak modules Makefile generated by Configure so that it handles
5978 the test case of no modules being selected. [chaz@reliant.com]
5980 *) Added a <LimitExcept method ...> sectioning directive that allows
5981 the user to assign authentication control to any HTTP method that
5982 is *not* given in the argument list; i.e., the logical negation
5983 of the <Limit> directive. This is particularly useful for controlling
5984 access on methods unknown to the Apache core, but perhaps known by
5985 some module or CGI script. [Roy Fielding, Tony Finch]
5987 *) Prevent apachectl from complaining if the PIDFILE exists but
5988 does not contain a process id, as might occur if the server is
5989 being rapidly restarted. [Wilfredo Sanchez]
5991 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
5993 *) Entity tag comparisons for If-Match and If-None-Match were not being
5994 performed correctly -- weak tags might cause false positives. Also,
5995 strong comparison wasn't properly enforced in all cases.
5996 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
5998 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
6001 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
6002 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
6004 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
6005 to util.c for parsing an HTTP header field value to extract the next
6006 list item, taking into account the possible presence of nested comments,
6007 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
6008 insignificant whitespace and lowercases non-quoted tokens.
6009 [Roy Fielding] PR#2065
6011 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
6012 code different from 500. This allows the proxy to, e.g., return
6013 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
6015 *) Fix ordering of language variants for the case where the traditional
6016 negotiation algorithm is being used with multiple language variants
6017 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
6019 *) Do not round the TCN quality calculation to 5 decimal places,
6020 unlike RFC 2296, because the calculation might need 12 decimal places
6021 to get the right result. [Roy Fielding]
6023 *) Remove unused code to disable transparent negotiation when
6024 negotiating on encoding only, as we now handle encoding too
6025 (though this is nonstandard for TCN), remove charset=ISO-8859-1
6026 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
6027 some debugging statements within mod_negotiation. [Koen Holtman]
6029 *) Fixed a rare memory corruption possibility in mod_dir if the index
6030 file is negotiable and no acceptable variant can be found.
6031 [Dean Gaudet, Roy Fielding, Martin Kraemer]
6033 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
6034 searching the Win32 registry for script interpreters.
6037 *) Win32: The compiled-in default filename for the error log is now
6038 error.log, which matches the default in the distributed httpd.conf.
6041 *) Win32: Any error messages from -i or -u command line options are now
6042 displayed on the console output rather than sent to the error log.
6043 Also the "Running Apache..." message is not output unless Apache is
6044 going to serve requests. [Paul Sutton]
6046 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
6047 and use a private significator ('$apr1$') to mark passwords as
6048 being smashed with our own algorithm. Also abstract the password
6049 checking into a new ap_validate_password() routine. [Ken Coar]
6051 *) Win32: The filename validity checker now allows "COM" but refuses
6052 access to "COM1" through "COM4". This allows filenames such
6053 as "com.name" to be served. [Paul Sutton] PR#3769.
6055 *) BS2000: Adapt to the new ufork() system call interface which will
6056 make subtasking easier on the OSD/POSIX mainframe environment.
6059 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
6060 ap_compat.h. [David White <david@persimmon.com>] PR#3725
6062 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
6063 use `.db' instead of `.pag' not only for FreeBSD, but also when
6064 the NDBM library looks like Berkeley-DB based.
6065 [Ralf S. Engelschall] PR#3773
6067 *) Add ability to handle DES or MD5 authentication passwords.
6068 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
6070 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
6072 *) SECURITY: Avoid some buffer overflow problems when escaping
6073 quoted strings. (This overflow was on the heap and we believe
6074 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
6076 *) Let src/Configure be aware of CFLAGS options starting with plus
6077 signs as it's the case for the HP/UX compiler.
6078 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
6080 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
6081 and check to see if the tar we wind up with supports '-h'.
6082 [Jim Jagielski] PR#3671
6084 *) A consistent and conservative style for all shell scripts has been
6085 implemented. Basically, all shell string tests use the traditional
6086 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
6087 to protect against bare null variable strings (ie: wrapping both
6088 sides with double quotes and prepending 'x'). 'x' was chosen
6089 because it's more universal and hopefully easier for old shell
6090 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
6093 *) The status module now prints out both the main server generation as
6094 well as the generation of each process. Also, the vhost info is
6095 printed with '?notable'. [Jim Jagielski]
6097 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
6098 and this makes its functions available to things in src/support.
6101 Changes with Apache 1.3.4
6103 *) Renamed macros status_drops_connection to ap_status_drops_connection
6104 and vestigial scan_script_header to ap_scan_script_header_err,
6105 mostly for aesthetic reasons. [Roy Fielding]
6107 *) The query switch "httpd -S" didn't exit after showing the
6108 vhost settings. That was inconsistent with the other query functions.
6111 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
6112 filename to the end of the STANDARD_MODULE_STUFF. Its
6113 presence at the beginning prevented reporting of the filename
6114 for modules compiled before 1 January 1999. [Ken Coar]
6116 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
6117 to detect and prevent access to special DOS device file names.
6118 [Paul Sutton, Ken Parzygnat]
6120 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
6121 and Makefile_win32_debug.txt (debug build) that work on Win95.
6122 Run each of the following from the src directory:
6123 nmake /f Makefile_win32.txt # compiles normal build
6124 nmake /f Makefile_win32.txt install # compiles and installs
6125 nmake /f Makefile_win32.txt clean # removes compiled junk
6126 nmake /f Makefile_win32_debug.txt # compiles debug build
6127 nmake /f Makefile_win32_debug.txt install
6128 nmake /f Makefile_win32_debug.txt clean
6131 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
6132 to build binary distributions. [Lars Eilebrecht]
6134 *) IndexOptions SuppressColumnSorting only turned off making
6135 the column headers anchors; you could still change the display
6136 order by manually adding a '?N=A' or similar query string to the
6137 URL. Now SuppressColumnSorting locks in the sort order so
6138 it can't be overridden this way. [Ken Coar]
6140 *) Added IndexOrderDefault directive to supply a default sort order
6141 for FancyIndexed directory listings. [Ken Coar] PR#1699
6143 *) Change the ap_assert macro to a variant that works on all platforms.
6144 [Richard Prinz <richard.prinz@cso.net>] PR#2575
6146 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
6147 search for an underscore on dlsym() (as it's already the case
6148 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
6150 *) Small fix for mod_env.html: The module was documented as to be _not_
6151 compiled into Apache per default, although it _IS_ compiled into
6152 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
6154 *) Instead of fixing a bug in the generation procedure for config.status (a
6155 backslash was missing) we remove the bug together with it's complete
6156 context because the special cases of the past can now no longer occur
6157 because of the recent magic for the --with-layout default.
6158 [Ralf S. Engelschall] PR#3590
6160 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
6161 making sure the src/support/ tools are _forced_ to be build last (they
6162 depend on other libraries).
6163 [Markus Theissinger <markus.theissinger@gmx.de>]
6165 *) Fix installation procedure: Now that os-inline.c is actually used (a
6166 recently fixed bug prevented this) we need to also install os-include.c
6167 in addition to os.h into the PREFIX/include/ location or building of
6168 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
6170 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
6171 allow us to distinguish between a garbled DSO (or even a file which isn't
6172 an Apache module DSO at all) and a DSO which doesn't match the current
6173 Apache API. [Ralf S. Engelschall] PR#3152
6175 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
6176 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
6177 match case insensitive (this especially avoids nasty patterns like
6178 `[tT][eE][sS][tT]'). Second two additional internal map functions
6179 `escape' and `unescape' were added which can be used to escape/unescape
6180 to/from hex-encodings in URLs parts (this is especially useful in
6181 combination with map lookups).
6182 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
6184 *) Renamed the macro escape_uri() to ap_escape_uri() which was
6185 forgotten (because it was a macro) in the symbol renaming process.
6186 [Ralf S. Engelschall]
6188 *) Fix some inconsistencies related to the scopes of directives. The only
6189 user visible change is that the directives `UseCanonicalName' and
6190 `ContentDigest' now use the (more correct) `Options' scope instead of
6191 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
6193 *) Using DSO, the Server token was being mangled. Specifically, the
6194 module's token was being added first before the Apache token. This
6195 has been fixed. [Jim Jagielski]
6197 *) Major overhaul of mod_negotiation.c, part 2.
6198 - properly handle "identity" within Accept-Encoding.
6199 - allow encoded variants in RVSA negotiation and let them appear in
6200 the Alternates field using the non-standard "encoding" tag-list.
6201 - fixed both negotiation algorithms so that an explicitly accepted
6202 encoding is preferred over no encoding if "identity" is not
6203 included within Accept-Encoding.
6204 - added ap_array_pstrcat() to alloc.c for efficient concatenation
6205 of large substring sequences.
6206 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
6209 *) Major overhaul of mod_negotiation.c, part 1.
6210 - cleanups to mod_negotiation comments and code structure
6211 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
6212 support for everything in the upcoming HTTP/1.1
6213 revision (draft-ietf-http-v11-spec-rev-06.txt).
6214 - language tag matching also handles tags with more than 2
6216 - empty Accept, Accept-Language, Accept-Charset headers are
6217 processed correctly; previously an empty header would make all
6218 values acceptable instead of unacceptable.
6219 - allowed for q values in Accept-Encoding
6220 - added support for transparent content negotiation (rfc2295 and
6221 rfc2296) (though we do not implement all features in these drafts,
6222 e.g. no feature negotiation). Removed old experimental version.
6223 - implemented 'structured entity tags' for better cache correctness
6224 (structured entity tags ensure that caches which can deal with Vary
6225 will (eventually) be updated if the set of variants on the server
6227 - this involved adding a vlist_validator element to request_rec
6228 - this involved adding the ap_make_etag() function to the global API
6229 - modified guessing of charsets used by Apache negotiation algorithm
6230 to guess 'no charset' if the variant is not a text/* type
6231 - added code to sort multiviews variants into a canonical order so that
6232 negotiation results are consistent across backup/restores and mirrors
6233 - removed possibility of a type map file resolving to another type map
6234 file as its best variant

6237 *) RFC2396 allows the syntax http://host:/path (with no port number)

6251 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
6252 rather late (too late for some invocations of TestCompile).
6253 This improves the make environment available to TestCompile and
6254 the *.module scripts. [Martin Kraemer]
6256 *) The hashbang emulation code in ap_execve.c would interpret
6257 #!/hashbang/scripts correctly, but failed to fall back to a
6258 standard shell for scripts which did NOT start with #!
6259 Now SHELL_PATH is started in these cases. [Martin Kraemer]
6261 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
6264 *) Update APXS manual page: some -q option arguments were missing
6265 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
6267 *) Cleanup the command line options: `-?' was documented to show
6268 the usage list but does it with an error because `?' is not a valid
6269 command. OTOH a lot of users expect `-h' to print such a usage list and
6270 instead are annoyed for ages by our huge unreadable list of directives.
6271 So we now changed the command line options this way:
6273 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
6274 very similar to the popular linker option.
6276 Intent: while -l gives the small list of modules, -L now gives the
6277 large list of directives implemented by these modules. This is also
6278 consistent with -v (short version info) and -V (large version info).
6280 Intent: it's now the expected option ;-)
6281 The manual page was adjusted accordingly.
6282 [Ralf S. Engelschall] PR#2714
6284 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
6285 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
6287 *) Removed recently introduced bugs and disfigurements in APACI:
6288 o fixed argument line processing: using $args was broken: It was not
6289 initialized and using args="$args $apc_option" and even args="$args
6290 \"$apc_option\"" fails in the second processing round for any arguments
6291 containing whitespaces. The only correct way is to use the construct
6292 "$@" (but not possible here) or iterate _both_ times over the implicit
6293 argument line (no argument to for-loop) which is what we now use.
6294 o make --with-layout=Apache the default without creating
6295 redundancy (copying the --with-layout block in the argument parsing
6296 loop). We achieve this by using the "$@" construct together with the
6297 `set' command to prepend --with-layout=Apache to the command line in
6298 case --with-layout is not used.
6299 o fixed auto-suffix handling now that config.layout exists.
6300 Paths which are auto-suffixed are marked with a trailing plus sign in
6301 config.layout and every path now can be marked this way (not only the
6302 four paths for which we do it currently). Additionally the suffix is
6303 no longer a static one. Instead it's now `/<target>' where <target> is
6304 the argument of the --target option or per default `httpd'.
6305 o allow also tabs (and only spaces) where we match whitespaces
6306 o various fixes and cleanups related to used shell coding style
6307 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
6308 o trimmed output of --help to fit into 80 columns
6309 [Ralf S. Engelschall]
6311 *) Added two new core API functions, ap_single_module_configure() and
6312 ap_single_module_init(), which are now used by mod_so to configure a module

6318 [Roy Fielding, Curt Sampson] PR#3120

6328 defined before it might be used. [Victor Khimenko]
6330 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
6331 [Tom Serkowski <tks@bsdi.com>] PR#3453
6333 *) Make generation of src/Configuration.apaci more robust: It failed to
6334 differenciate between modules when one module name was a postfix of
6335 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
6336 just XXX (think about totally non-standard names like "apache_ssl", too).
6337 [Ralf S. Engelschall] PR#3380
6339 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
6340 since 1.3b7) and make whitespace handling more robust (it failed horrible
6341 when whitespaces were present in the arguments of -D options).
6342 [Ralf S. Engelschall] PR#3240
6344 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
6345 creates an external package shadow tree in DIR before the local build
6346 shadow tree is generated under DIR. This way one can have the extracted
6347 Apache distribution tree read-only on NFS or CDROM and still build Apache
6348 from these sources. An automatically triggered VPATH-like mechanism is
6349 provided through the TOP variable, too.

6363 and the usage page was inconsistent with the functionality and manpage.
6364 [Ralf S. Engelschall]
6366 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
6367 They can occur multiple times and their arguments (`xxx') are passed AS
6368 IS to the compiler/linker command. [Ralf S. Engelschall]
6370 *) Fixed possible (but harmless in practice) bug in the DBM lookup
6371 procedure of mod_rewrite: very long keys were truncated.
6372 [Ralf S. Engelschall]
6374 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
6375 identifier, currently "Apache" and "GNU" are pre-defined in the file
6376 config.layout. Custom layouts are possible by using FILE:ID as the
6377 argument where the layout ID is taken from FILE.
6379 The config.layout file consists of <Layout ID>..</Layout> sections
6380 where inside those sections "path_variable: path_value" pairs can be
6381 specified. These lines are converted to path_variable='path_value'.
6383 *) Add a DefaultLanguage directive so that files missing a language
6384 extension (e.g., .fr, .de) can be labelled as being some other
6385 default language. DefaultLanguage can appear in <Directory> and
6386 <Files> containers as well as .htaccess files. [Paul Sutton]
6389 *) Fix TARGET configuration when configuring and installing using
6390 APACI configure. TARGET now defines the basename of the configuration
6391 file, startup script, manual page, etc. log_error_core() now reports
6392 the server binary name given by argv[0]. TARGET can now also be defined
6393 with --target=TARGET parameter passed to APACI configure.

6500 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
6501 in the Configuration[.apaci] file. Two special and important variants are
6502 supported for the option argument: first BEGIN:foo which permutes module
6503 mod_foo with the begin of the module list, i.e. it `moves' the module to
6504 the begin of the list (gives it lowest priority). And second foo:END
6505 which permutes mod_foo with the end of the module list, i.e. it `moves'
6506 the module to the end of the list (gives it highest priority).

6585 of the protocol processing, which is extra nice because it works
6586 between continuation lines, is almost no cost in the normal case
6587 of no extra whitespace, and saves memory. [Roy Fielding]

6669 that missing files are not confused with unreadable files.
6672 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
6673 errno on an error, which leads to one error being mistaken for

6700 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
6701 mod_auth_db to both be friendly to users who wants to use this version
6702 and to avoid problems under platforms where only version 2.x is present.
6703 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
6705 *) When using ap_log_rerror(), make the error message available to the
6706 *ERROR_NOTES envariables by default. [Ken Coar]
6708 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
6709 You now must define a BS2000Account name for the server User.
6710 This has fewer security implications than the old approach.
6713 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
6714 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
6715 platform to make the braindead HPUX linker happy. Notice, for the module
6716 DSOs we don't have to use this, because these are loaded manually (and
6717 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

6726 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
6728 *) Make PrintPath work generically instead of having one version
6729 strictly for OS/2. [Jim Jagielski, Brian Havard]
6731 *) Fix the recently introduced C header file checking: We now use the C
6732 pre-processor pass only (and no longer the complete compiler pass) to
6733 determine whether a C header file exists or not. Because only this way
6734 we're safe against inter-header dependencies (which caused horrible
6735 portability problems). The only drawback is that we now have a CPP
6736 configuration variable which has to be determined first (we do a similar
6737 approach as GNU Autoconf does here). When all fails the user still has
6738 the possibility to override it manually via APACI or src/Configuration.
6739 As a fallback for the header check itself we can directly check the
6740 existance of the file under /usr/include, too.

6772 platform, because it's only supported under version 4.0 and higher. But
6773 because our GuessOS is still unaware of Digital UNIX versions and the
6774 -msym is just to optimize the DSO statup time a little bit it's safe and
6775 best when we leave it out now. [Ralf S. Engelschall] PR#2969
6777 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
6778 functions: First all three functions no longer fail on strings containing
6779 "%" chars and second ap_log_printf() no longer does a double-formatting
6780 (instead it directly passes through the message to be formatted to the
6781 real internal formatting function). [Ralf S. Engelschall] PR#2941
6783 *) Allow "Include" directives anywhere in the server config
6784 files (but not .htaccess files). [Ken Coar] PR#2727
6786 *) The proxy was refusing to serve CONNECT requests except to
6787 port 443 (https://) and 563 (snews://). The new AllowCONNECT
6788 directive allows the configuration of the ports to which a
6789 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
6791 *) mod_expires will now act on content that is not sent from a file
6792 on disk. Previously it would never add an Expires: header to
6793 any response that did not come from a file on disk; the only
6794 case where it still doesn't (and can't) add one for that type of
6795 content is if you are using a modification date based setting.
6796 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
6798 *) Problems encountered during .htaccess parsing or CGI execution
6799 that lead to a "500 Server Error" condition now provide explanatory
6800 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
6803 *) Add NameWidth keyword to IndexOptions directive so that the
6804 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
6807 *) Recognize lowercase _and_ uppercase `uname' results under
6808 SCO OpenServer. [David Coelho <drc@ppt.com>]
6810 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
6811 a common problem of (mis-administrated?) IIS servers, make the apache
6812 proxy immune to these errors (and ignore the duplicates, but log
6813 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
6815 *) The <IfModule and <IfDefine block starting directives now only
6816 allow exactly one argument. Previously, the optional negation
6817 character '!' could be separated by whitespace without a syntax
6818 error being reported, albeit defeating the IfModule functionality
6819 (enclosed directives would ALWAYS be executed). By using the
6820 stricter syntax, these hard-to-track errors can be avoided.
6823 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
6824 cause the standalone FancyIndexing directive to logically OR
6825 into any existing IndexOptions settings rather than wiping
6826 them out. [Ken Coar]
6828 *) Changes in ftp proxy: make URL parsing simpler by using the
6830 + Add display of the "current directory" in cases where it's
6831 different from the supplied path (e.g., ftp://user@host/ lives
6832 in /home/user, not in /, therefore clicking on "../" in the
6833 starting directory might send us to /home/).
6834 + When ftp login fails, (esp. when a user name was part of the
6835 URL already), we now return [401 Unauthorized ] to allow the
6836 browser to pop up an authorization dialog. This makes passwords
6837 slightly less visible (they don't appear in the regular log files)
6838 and implements a functionality that other www proxy servers
6842 *) Triggered by the recent "Via:" header changes, the proxy module would
6843 dump core for replies with invalid headers (e.g., duplicate
6844 "HTTP/1.0 200 OK" lines). These errors are now logged and the
6845 core dump is avoided. Also, broken replies are not cached.
6846 [Martin Kraemer] PR#2914
6848 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
6849 plop gmon.out profile data for each child [Doug MacEachern]
6851 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
6852 config.status script to be immune against arguments with whitespaces.
6853 [Yves Arrouye <yves@apple.com>] PR#2866
6855 *) Replace the inlined information grabbing stuff for the configuration
6856 adjustment feature (no --without-confadjust) with calls to a new helper
6857 script `buildinfo.sh' which is both more flexible and already proofed to
6858 be more robust against platform differences. This mainly fixes the
6859 recently occured ``sed: command garbled: ...'' problems.
6860 [Ralf S. Engelschall] PR#2776, PR#2848
6862 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
6863 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
6864 without complains after we recently added the POST feature.
6865 [Ralf S. Engelschall]
6867 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
6868 modules as API functions and we forgot them at the big symbol renaming.

6878 [Kurt Sussman <kls@best.com>] PR#2871
6880 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
6881 5 to 10 because there are some users out there who always have 5 to 8
6882 variables in one RewriteRule and had to patch mod_rewrite.h for every
6883 release. So 15 should be now more than enough, even for them. (I never
6884 needed more than 4 in my RewriteRules ;-)
6885 [Ralf S. Engelschall]
6887 *) Make the proxy generate and understand Via: headers
6890 *) Change the proxy to use tables instead of array_headers for
6891 the header lines. [Martin Kraemer]
6893 *) Make sure the config.status file is not overridden when just
6894 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
6896 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
6897 provide a way to trace API changes that add functionality but do
6898 not create a compatibility issue for precompiled modules, etc.
6899 See include/ap_mmn.h for more details. [Randy Terbush]
6901 *) Fix suexec installation under `make install root=xxx' situation.
6902 [Ralf S. Engelschall]
6904 *) Extend the output of the -V switch to include the paths of all
6905 compiled-in configuration files, if they were overridden at
6906 compile time, for least astonishment of the user.
6909 *) When READing a request in ExtendedStatus mode, the "old"
6910 vhost, request and client information is not displayed.
6913 *) STATUS is no longer available. Full status information now
6914 run-time configurable using the ExtendedStatus directive.
6917 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
6918 cpu time attacks) in header parsing. Add ap_overlap_tables(),
6919 a function which can be used to perform bulk update operations
6920 on tables in a more efficient manner. CAN-1999-1199 (cve.mitre.org)
6923 *) SECURITY: Added compile-time and configurable limits for
6924 various aspects of reading a client request to avoid some simple
6925 denial of service attacks, including limits on maximum request-line
6926 size (LimitRequestLine), number of header fields (LimitRequestFields),
6927 and size of any one header field (LimitRequestFieldsize). Also added
6928 a configurable directive LimitRequestBody for limiting the size of the
6929 request message body. [Roy Fielding]
6931 *) Make status module aware of DNS and logging states, even if
6932 STATUS not defined. [Jim Jagielski]
6934 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
6936 *) Enhance mod_speling so that CheckSpelling can be used in
6937 <Directory> containers and .htaccess files. [Ken Coar]
6939 *) API: new ap_custom_response() function for hooking into the
6940 ErrorDocument mechanism at runtime [Doug MacEachern]
6942 *) API: new ap_uuencode() function [Doug MacEachern]
6944 *) API: scan_script_header_err_core() now "public" and renamed
6945 ap_scan_script_header_err_core() [Doug MacEachern]
6947 *) The 'status' module will now show the process pid's and their
6948 state even without full STATUS accounting. [Jim Jagielski]
6950 *) Restore the client IP address to the error log messages, this
6951 was lost during the transition from 1.2 to 1.3. Add a new
6952 function ap_log_rerror() which takes a request_rec * and
6953 formats it appropriately. [Dean Gaudet] PR#2661
6955 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
6956 whitespace in input lines -- including within quoted strings.
6958 but leading and trailing whitespace should continue to be
6959 stripped [Martin Kraemer]
6961 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
6962 the ugly use of an env. variable and use command-line args for
6963 alternate $PATH. Make more like advanced 'type's as well.
6966 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
6967 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
6968 <alain.st-denis@ec.gc.ca>] PR#2736
6970 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
6972 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
6973 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
6974 directory was renamed to src/os/os2/ for consistency.
6975 [Brian Havard, Ralf S. Engelschall]
6977 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
6978 files (here modules) against other DSO files (here shared libraries).
6979 This is done by determining a subset of LIBS which can be safely used for
6980 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
6981 disabled for all platforms to avoid problems with this (experimental)
6982 rule. But we provide it now for those people how ran into problems and
6983 want to came out by forcing linking against DSOs.
6984 [Ralf S. Engelschall] PR#2587
6986 *) Fix suEXEC start message: Has to be of `notice' level to really get
6987 printed together with the standard startup message because the `notice'

6998 handling loop so that the connection can be properly closed with
6999 lingering_close, thus avoiding a potential TCP reset that would
7000 cause the client to miss the HTTP error response. [Roy Fielding]
7002 *) One more portability fix for APACI shadow tree support: Swap order of awk
7003 and sed in top-level configure script to avoid sed fails on some
7004 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
7005 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729

7062 the read_request error conditions of URI-too-long (414) and
7063 malformed header fields (400). [Roy Fielding] PR#2646
7065 *) Add support for the Max-Forwards: header line required by RFC2068 for
7066 the TRACE method. This allows apache to TRACE along a chain of proxies
7067 up to a predetermined depth. [Martin Kraemer]
7069 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled

7110 party packages and to again reach consistency:
7111 1. conf.h -> ap_config.h
7112 2. conf_auto.h -> ap_config_auto.h \ these are now merged

7115 5. apctype.h -> ap_ctype.h
7116 Backward compatibility files for conf.h and compat.h were created.
7118 *) mod_mmap_static will no longer take action on requests unless at
7119 least one "mmapfile" directive is present in the configuration.
7120 This experimental module has to do some black magic to operate
7121 inside the current API and thus creates side-effects for other

7179 *) The APACI libexecdir was not extended with an "apache/" subdir
7180 if the installation prefix didn't already contain "apache", but
7181 it should be because the DSO files are Apache-specific. Now
7182 libexecdir is treated the same way sysconfdir, datadir, localstatedir

7261 user. Package authors can use the --without-confadjust option to disable
7262 these configuration adjustments.

7271 as <IfModule>..</IfModule> sections) which can be used to skip or process

7287 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
7288 in top-level configure script to avoid sed fails on some platforms (for

7290 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
7292 *) Improve performance of directory listings (mod_autoindex) by comparing
7293 integer keys (last-modified and size) as integers rather than converting
7294 them to strings first. Also use a set of explicit byte tests rather
7295 than strcmp() to check for parent directory-ness of an entry. Oh, and
7296 make sure the parent directory (if displayed) is *always* listed first
7297 regardless of the sort key. Overall performance winnage should be good
7298 in CPU time, instruction cache, and memory usage, particularly for large
7299 directories. [Ken Coar]
7301 *) Add a tiny but useful goody to APACI's configure script: The generation
7302 of a config.status script (as GNU Autoconf does) which remembers the used
7303 configure command and hence can be used to restore the configuration by
7304 just re-running this script or for remembering the configuration between

7308 *) Add httpd -t (test) option for running configuration syntax tests only.
7309 If something is broken it complains and exits with a return code
7310 non-equal to 0. This can be used manually by the user to check the Apache
7311 configuration after editing and is also automatically used by apachectl
7312 on (graceful) restart command to make sure Apache doesn't die on restarts
7313 because of a configuration which is now broken since the last (re)start.
7314 This way `apachectl restart' can be used inside cronjobs without having
7315 to expect Apache to be falling down. Additionally the httpd -t can be run
7316 via `apachectl configtest'.

7456 spawn_child was obsoleted and moved to compat.h

7460 programs: ap_spawn_child_err() is used and the Win32 case now uses
7461 CreateProcess() instead of a low-level execl() (which caused problems in

7465 *) A few cosmetics and trivial enhancements to APXS to make the
7466 generated Makefile more user friendly. [Ralf S. Engelschall]
7468 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
7469 was updated to use the normal apache error processing, thereby allowing
7470 proxy errors to be treated by ErrorDocument's as well. For this
7471 purpose, a new module-to-core communication variable "error-notes"
7472 was introduced; the proxy (and possibly other modules) communicates
7473 its error text using this variable. Its content is copied to a new
7474 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
7475 The old proxy special error routine ap_proxy_log_uerror()

7483 *) Transform the configure message "You need root privileges for suEXEC"
7484 from a fatal error into a (more friendly) warning because the building
7485 ("make") of Apache we can allow, of course. Root privileges are needed
7486 only for the installation step ("make install"). So make sure the

7551 *) The proxy cache would store an incorrect content-length in the cached

7553 of the original copy instead of using the cached copy.
7554 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
7556 *) The Makefiles assumed that DSO files are build via $(LD). This
7557 is broken for two reasons: First we never defined at least LD=ld
7558 somewhere to make sure this works (it was silently assumed that most Make
7559 provide a built-in LD definition - ARGL!) and second using the generic LD
7560 variable is not the truth. Instead a special variable named LD_SHLIB is
7561 reasonable because although "ld" is usually the default, the command for
7562 building DSO files can be "libtool" or even "cc" on some systems.
7563 [Ralf S. Engelschall]
7565 *) Replace the AddVersionPlatform directive with ServerTokens which
7566 provides for more control over the format of the Server:

7575 not retrieved in src/Configure and thus was not useable.
7576 [Ralf S. Engelschall]
7578 *) Various Makefile consistency cleanups:
7579 - make OSDIR also automatically be relative to src/ like INCDIR
7580 - SUBDIRS is now generated in src/Makefile only and not in
7581 Makefile.config because it is a local define for this location.
7582 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
7583 any Makefile but make sure that at least the "-K inline" is kept in
7585 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
7586 - updated the dependencies theirself
7587 - removed not existing SHLIB variable from "clean" targets
7588 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
7589 already exists and OBJS_PIC are also just plain objects and have not
7590 directly to do with "shared" things. The only difference is that they
7591 contain PIC. So OBJS_PIC is the more canonical name.
7592 - Updated the Makefile-dependency lines for OBJS_PIC
7593 - Removed the Makefile-dependency line in Configure to avoid double
7595 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
7596 of xxx.lo as GNU libtool does with its PIC objects
7597 - reduce local complexity in modules Makefile.tmpl by moving the last
7598 existing target "depend" to the generation section in Configure, too.
7599 - removed the historical $(SPACER) which was used in the past together
7600 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
7601 is no longer needed.
7602 - force the build and run of the gen_xxx programs under main/ as the
7603 first step before building the objects because it looks cleaner
7604 [Ralf S. Engelschall]

7613 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
7615 *) When opening "configuration" files (like httpd.conf, htaccess
7616 and htpasswd), Apache will not allow them to be non-/dev/null
7617 device files. This closes a DoS hole. At the same time,
7618 we use ap_pfopen to open these files to handle timeouts.
7619 [Jim Jagielski, Martin Kraemer]
7621 *) Apache will now log the reason its httpd children exit if they exit
7622 due to an unexpected signal. (It requires a new porting define,
7623 SYS_SIGLIST, which if defined should point to a list of text
7624 descriptions of the signals available. See PORTING.) [Dean Gaudet]
7626 *) WIN32: chdir() doesn't make sense in a multithreaded environment
7627 like WIN32. Before, Win32 CGI's could have had sporadic failures
7628 if a chdir call from one thread was made between another chdir call
7629 and a spawn in another thread. So, for now don't chdir for CGI scripts
7630 in WIN32. The current CGI "spec" is unclear as to whether it's
7631 necessary. Long-term fix is to either serialize the chdir/spawn combo
7632 or use WIN32 native calls to spawn a process. This temp fix was
7633 necessary to remove this as a showstopper for 1.3's release.
7636 *) Cleanup the suEXEC support in APACI and make it more safe:
7637 1. Add big fat hint in INSTALL about risks and to read the
7638 htdocs/manual/suexec.html document before using the suexec-related
7640 2. Make sure the user has at least provided one --suexec-xxxx option
7641 (specifies suEXEC parameters) in addition to --enable-suexec option.
7642 If only --enable-suexec is given APACI stops with a hint to INSTALL
7643 and htdocs/manual/suexec.html documents.
7644 3. Provide two additional --suexec-xxxx options to make the suEXEC
7645 configuration complete (especially for package maintainers who else
7646 had to patch the source tree) by providing ways to configure minimal
7647 UID/GID and safe PATH, too.
7648 [Ralf S. Engelschall]
7650 *) Cleanup of the `configure --shadow' process:
7651 - make sure the configure script creates its temporary files in the
7652 shadow tree to avoid conflicts with parallel configure runs
7653 - removed unnecessary option "-r" from "rm" call for Makefiles
7654 - make sure the configure scripts creates the shadow-wrapper Makefile
7655 only when no shadow trees already exists
7656 - make sure "make distclean" removes the shadow-wrapper Makefile but only
7657 when no more shadow trees exists
7658 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
7659 as fast (in the past it needed 70sec, now it runs just 38sec)
7660 - make sure CVS does not complain about the created files
7661 Makefille.<gnutriple> and directories src.<gnutriple>
7662 [Ralf S. Engelschall]
7664 *) Added the ap_add_version_component() API routine and the
7665 AddVersionPlatform core directive. The first allows modules to
7666 declare themselves in the Server response header field value,
7667 augmenting the SERVER_SUBVERSION define in the Configuration file
7668 with run-time settings (more useful in a loadable-module environment).
7669 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
7670 into the server version string. [Ken Coar] PR#2056
7672 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
7675 *) Emit the "Accept-Range" header for the default handler.
7676 [Brian Behlendorf] PR#1464
7678 *) Add a note to httpd.conf-dist that apache will on some systems fail
7679 to start when the Group # is set to a negative or large positive value.
7682 *) Make sure the module execution order is correct even when some modules
7683 are loaded under runtime (`LoadModule') via the DSO mechanism:
7684 1. The list of loaded modules is now a dynamically allocated one
7685 and not the original statically list from modules.c
7686 2. The loaded modules are now correctly setup by LoadModule for
7687 later use by the AddModule command.
7688 3. When the DSO mechanism for modules is used APACI's `install'
7689 target now enables all created `LoadModule' lines per default because
7690 this is both already expected by the user _and_ needed to avoid
7691 confusion with the next point and reduces the Makefile.tmpl complexity
7692 4. When the DSO mechanism for modules is used, APACI's `install'
7693 target now additionally makes sure the module list is reconstructed
7694 via a complete `ClearModuleList+AddModule...' entry.
7695 5. The support tool `apxs' now also makes sure an AddModule command
7696 is added in addition to the LoadModule command.
7697 6. The modules.c generation was extended to now contain two
7698 comments to make sure no one is confused by the confusing terminology
7699 of loading/linking (we use load=link+load & link=activate instead of
7700 the obvious load=activate & link=link :-( )
7701 This way now there is no longer a difference under execution time between
7702 statically and dynamically linked modules.
7703 [Ralf S. Engelschall]
7705 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
7706 Big Symbol Renaming. [Ralf S. Engelschall]
7708 *) Add a comment to mod_example.c showing the format of a FLAG command
7711 *) Standardized the time format in mod_status to match that of other
7712 places in the code (e.g. DATE_GMT). PR#1551
7714 *) Fix handling of %Z in timefmt strings for those platforms with no time
7715 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
7718 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
7719 feature compatible with 'UseCanonicalName off' by changing
7720 r->server->server_hostname to ap_get_server_name(). And I changed some
7721 functions which use r->server->port to use ap_get_server_port() instead,
7722 because if there's no Port directive in the config r->server->port is 0.
7725 *) get/set_module_config are trivial enough to be better off inline. Worth
7726 1.5% performance boost. [Dean Gaudet]
7728 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
7729 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
7732 *) [BS2000 security] BS2000 needs an extra authentication to initialize
7733 the task environment to the unprivileged User id. Otherwise CGI scripts
7734 would have a way to gain super user access. [Martin Kraemer]
7736 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
7737 absolute path, only log base name of logging source as is done
7738 in unix. [Martin Kraemer]
7740 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
7741 the encoding type from the Accept-Encoding header (if it's there)
7742 and use it in the response, as that's probably what it'll be expecting.
7743 [Ronald.Tschalaer@psi.ch]

7756 of APEXIT_CHILDFATAL) the parent process to abort and
7757 shutdown the server if the error in the child process was
7758 fatal enough. [Jim Jagielski]

7767 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
7769 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
7772 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
7773 Additionally the checks for finding the vendor DSO library were moved
7774 from mod_so.c to Configure because first it needs $PLAT etc. and second
7775 mod_so already uses an abstraction layer and does not fiddle with the
7776 vendor functions itself.
7777 [Jens-Uwe Mager, Ralf S. Engelschall]
7779 *) PORT: Some optimization defines for NetBSD
7780 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
7782 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
7783 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
7785 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
7786 AIX variants should work fine, too. Even AIX 3.x should work). This is
7787 accomplished by using the free DSO emulation code from Jens-Uwe Mager
7788 which we put into a os/unix/os-dso-aix.c file.
7789 [Ralf S. Engelschall]
7791 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
7792 that we should use NET_SIZE_T == int but the include files force size_t.
7793 [Ralf S. Engelschall]
7795 *) Fix two bugs in select() handling in http_main.c.
7798 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
7799 is unset (as it is in situations like timeouts) where it is unclear
7800 whether errno is set or not. [Martin Kraemer]
7802 *) Just having APACI's localstatedir is too general and not enough for most
7803 of the systems. 1.3b6 again required manual APACI patches by package
7804 maintainers from Red Hat and FreeBSD because for their filesystem layout a
7805 little bit more flexibility in configuring the paths is needed. Hence we
7806 provide three additional configure options (--runtimedir, --logfiledir,
7807 --proxycachedir) which now can be used for more granular adjustments if
7808 --localstatedir is not enough to fit the particular needs. As a nice
7809 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
7810 [Ralf S. Engelschall]
7812 *) Make the install root for "make install" in APACI's Makefile overrideable
7813 by package authors. This way we are even more friendly to package
7814 maintainers (especially Debian and Red Hat) who build for the real prefix
7815 via "configure --prefix=/<real>" but use a different local prefix via
7816 "make root=/tmp/apache install" for rolling the package without bristling
7817 the target location on their system.
7818 [Ralf S. Engelschall]
7820 *) Workaround sed limitations in APACI's configure script by now
7821 substituting in chunks of 50 commands (because for instance HPUX's vendor
7822 sed has a limit of max. 98 commands)
7823 [Ralf S. Engelschall] PR#2136
7825 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
7826 [Ralf S. Engelschall] PR#2140
7828 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
7829 RENAMING process because they are defined as pre-processor macros instead
7830 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
7831 [Ralf S. Engelschall]
7833 *) Workaround braindead AWK's when generating ap_config.h: The split() and
7834 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
7835 [Ralf S. Engelschall] PR#2139
7837 *) Various bugfixes and cleanups for the APACI configure script:
7838 o fix IFS handling for _nested_ situation
7839 o fix Perl interpreter search: take first one found instead of last one
7840 o fix DSO consistency check
7841 o print error messages to stderr instead of stdout
7842 o add install-quiet for --shadow situation to Makefile stub
7843 o reduce complexity by avoiding sed-hacks for rule and module list loops

7846 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
7848 *) Make sure the input field separator (IFS) shell variable is explicitly
7849 initialized correctly before _every_ `for' loop and also restored after
7850 the loops. [Ralf S. Engelschall]
7852 *) Make sure that "make install" doesn't overwrite the `mime.types' and
7853 `magic' files from an existing Apache installation. Because people often
7854 customize these for own MIME and content types.

7892 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
7894 *) If you start apache with the -S command line option it will dump

7896 to figure out what is wrong with their vhost configuration.
7897 (Other dumps may be added in the future.) [Dean Gaudet]
7899 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
7900 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
7903 *) Because /usr/local/apache is the default prefix the ``configure
7904 --compat'' option no longer has to set prefix, again. This way the
7905 --compat option honors a leading --prefix option. [Lars Eilebrecht]
7907 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
7908 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
7909 to avoid "discard const" warnings. [Ralf S. Engelschall]
7911 *) If a specific handler is set for a file yet the request still
7912 ends up being handled by the default handler, log an error
7913 message before handling it. This catches things such as trying
7914 to use SSIs without mod_include enabled. [Marc Slemko]
7916 *) Fix error logging for the startup case where ap_log_error() still uses
7917 stderr as the target. Now the default log level is honored here, too.
7918 [Ralf S. Engelschall]

7925 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
7927 Changes with Apache 1.3b6
7929 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
7931 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
7932 interface via the similar but proprietary HP/UX shl_xxx-style system
7933 calls. [Ralf S. Engelschall]
7935 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
7936 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
7937 Make. [Ralf S. Engelschall]
7939 *) ++++ THE BIG SYMBOL RENAMING ++++
7940 To avoid symbol clashes with third-party code compiled into the server,
7941 we globally applied the prefix "ap_" to the following classes of
7943 - Apache provided general functions (e.g., ap_cpystrn)
7944 - Public API functions (e.g., palloc, bgets)
7945 - Private functions which we can't make static (because of
7946 cross-object usage) but should be (e.g., new_connection)
7947 For backward source compatibility a new header file named compat.h was
7948 created which provides defines for the old symbol names and can be used
7949 by third-party module authors.
7952 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
7953 problem under SVR4 is that there is no command flag to force the linker
7954 to export the global symbols of the httpd executable therewith they are
7955 available to the DSO's. Instead of problematic hacks like creating a
7956 dummy.so file (containing dummy references to all global symbols) the
7957 httpd binary is linked against, we use a clean trick stolen from Perl 5:
7958 Placing the Apache core code itself into a DSO library named libhttpd.so.
7959 This way the global symbols _HAVE_ to be exported and thus are available
7960 to any manually loaded DSO's under runtime. To reduce the impact to the
7961 user to null we go even further and create a stub httpd executable which
7962 automatically keeps track of the DSO library loading itself and thus
7963 hides the complete mechanism from the user. Although the generation of
7964 this DSO library is automatically triggered for platforms which
7965 essentially need it (mostly all SVR4-derivates) it can be also enabled
7966 manually via the Rule SHARED_CORE. This can be interesting in the future
7967 where we perhaps exploit this libhttpd.so mechanism for providing nifty
7968 features like graceful upgrades, or whatever.
7969 [Ralf S. Engelschall, Martin Kraemer]
7971 *) Build the libraries before building the rest of the tools. [Ben Hyde]
7973 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
7974 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
7975 conventions while "clean" removes only stuff created by "all" targets,
7976 "distclean" additionally removes the stuff from the configuration
7977 process. This way "make distclean" (hence the name) provides a fresh
7978 source tree as it was for distribution.
7979 [Ralf S. Engelschall]
7981 *) Allow top-level (APACI) Makefile to break on build errors
7982 the same way the src/ subtree Makefiles breaks on them by replacing the
7983 initial APACI sed-subdir-display-kludge with a more clean
7984 variable-passing-solution: variable SDP can optionally hold the subdir
7985 prefix which is consistently used for displaying the subdir movement.
7986 This way even the top-level Makefile can stop correctly on errors as the
7987 user expects. [Ralf S. Engelschall]
7989 *) Fixed ordering of argument checks for RewriteBase directive.
7990 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
7992 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
7993 indicating that a module is being compiled for dynamic loading. Also
7994 remove #define IS_MODULE from modules and add SHARED_MODULE define
7995 to the mak/dsp files. [Alexei Kosut]
7997 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
7998 since we are now logging APLOG_WARNING by default. [Roy Fielding]
8000 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
8002 *) Add documentation file and src/Configuration.tmpl entry for the
8003 experimental mod_mmap_static module. Because although it is and marked as
8004 an experimental one it is distributed and thus should be documented and
8005 prepared for configuration the same way as all others modules.
8006 [Ralf S. Engelschall]
8008 *) Add query (-q) option to apxs support tool to be able to manually query
8009 specific settings from apxs. This is needed for instance when you
8010 manually want to access Apache's header files and you need to assemble
8011 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
8012 [Ralf S. Engelschall]
8014 *) Now src/Configure uses a fallback strategy for the shared object support
8015 on platforms where no explicit information is available: If a Perl
8016 installation exists we ask it about its shared object support and if it's
8017 the dlopen-style one we shamelessly guess the compiler and linker flags
8018 for creating shared objects from Perls knowledge. Of course, the user is
8019 warning about what we are doing and informed that he should send us
8020 the guessed flags when they work. [Ralf S. Engelschall]
8022 *) Provide APACI --without-support option to be able to disable the build
8023 and installation of the support tools from the src/support/ area.
8024 Although its useful to have these installed per default we should provide
8025 a way to compile and install without them for backward-compatibility.
8026 [Ralf S. Engelschall]
8028 *) Add of the new APache eXtenSion (apxs) support tool for building and
8029 installing modules into an _already installed_ Apache package through the
8030 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
8031 this approach actually doesn't need the Apache source tree. The
8032 (APACI-installed) server package is enough, because this now includes the
8033 Apache C header files (PREFIX/include) and the new APXS tool
8034 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
8035 module authors to build their Apache modules _OUTSIDE_ the Apache source
8036 tree while avoiding them to fiddle around with the totally platform
8037 dependend way of compiling DSO files. The tool supports all ranges of
8038 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
8039 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
8040 on-the-fly generate a minimalistic Makefile and sample module for the
8041 first step to provide both a quick success event and to demonstrate the
8042 APXS mechanism to module authors. [Ralf S. Engelschall]
8044 *) Fix core dumps in use of CONNECT in proxy.
8045 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
8047 *) Modify the log directives in httpd.conf-dist files to use CustomLog
8048 so that users have examples of how CustomLog can be used.
8051 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
8052 the Apache distribution tree. Until Apache 1.3 there was no real
8053 out-of-the-box batch-capable build and installation procedure for the
8054 complete Apache package. This is now provided by a top-level "configure"
8055 script and a corresponding top-level "Makefile.tmpl" file. The goal is
8056 to provide a GNU Autoconf-style frontend which is capable to both drive
8057 the old src/Configure stuff in batch and additionally installs the
8058 package with a GNU-conforming directory layout. Any options from the old
8059 configuration scheme are available plus a lot of new options for flexibly
8060 customizing Apache. [Ralf S. Engelschall]
8062 *) The floating point ap_snprintf code wasn't threadsafe.

8072 Configure knows which CC we are using. [Jim Jagielski]
8074 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
8075 was defined in a parent directory. [Lars Eilebrecht]
8077 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
8078 a generic printf-style routine that can call arbitrary output
8079 routines. Use this to replace http_bprintf.c. Add new routines
8080 psprintf(), pvsprintf() which allocate the exact amount of memory
8081 required for a string from a pool. Use psprintf() to clean up
8082 various bits of code which used ap_snprintf()/pstrdup().
8085 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
8086 ap_snprintf() has different semantics and formatting codes than
8087 snprintf(). [Dean Gaudet]
8089 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
8090 is necessary on at least Solaris where the /etc/rc?.d scripts
8091 are run with these signals ignored, and "SIG_IGN" settings are
8092 maintained across exec().

8120 *) Allow %2F in two situations: 1) it is in the query part of the URI,
8121 therefore not exposed to %2F -> '/' translations and 2) the request
8122 is a proxy request, so we're not dealing with a local resource anyway.
8123 Without this, the proxy would fail to work for any URL's with

8134 characters. While this normally doesn't stop anything from
8135 working, it can result in extra collisions.
8136 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
8138 *) Now mod_proxy uses the response string (in addition to the response status
8139 code) from the already used FTP SIZE command to setup the Content-Length
8140 header if available. [Ralf S. Engelschall] PR#1183
8142 *) Reanimated the (still undocumented) proxy receive buffer size directive:
8143 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
8144 name was really too generic, added documentation for this directive to
8145 the mod_proxy.html and corrected the hyperlink to it in the
8146 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
8148 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
8149 faster [Martin Kraemer]
8151 *) Make Configure die when you give it an unknown command switch.
8154 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
8155 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
8156 and per default compiled support programs have manual pages - just to
8157 document our stuff a little bit more and to be able to do really
8158 Unix-like installations ;-) [Ralf S. Engelschall]
8160 *) Major cleanups to the Configure script to make it and its generated
8161 Makefiles again readable and maintainable: add SRCDIR option, removed
8162 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
8163 generated sections, consequently added Makefile headers with inheritance
8164 information, added subdir movement messages for easier following where
8165 the build process currently stays (more verbose then standard Make, less
8166 verbose than GNU make), same style to comments in the Configure script,
8167 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
8169 *) Add the new ApacheBench program "ab" to src/support/: This is derived
8170 from the ZeusBench benchmarking program and can be used to determine the
8171 response performance of an Apache installation. This version is
8172 officially licensed with Zeus Technology, Ltd. See the license agreement
8173 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
8174 [Ralf S. Engelschall]
8176 *) API: Various core functions that are definately not part of the API
8177 have been made static, and a few have been marked API_EXPORT. Still
8178 more have been marked CORE_EXPORT and are not intended for general
8179 use by modules. [Doug MacEachern, Dean Gaudet]
8181 *) mod_proxy was not clearing the Proxy-Connection header from
8182 requests; now it does. This did not violate any spec, however
8183 causes poor interactions when you are talking to remote proxies.

8192 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
8194 *) Clean up some undocumented behavior of mod_setenvif related to
8195 "merging" two SetEnvIf directives when they match the same header
8196 and regex. Document that mod_setenvif will perform comparisons in
8197 the order they appear in the config file. Optimize mod_setenvif by
8198 doing more work at config time rather than at runtime.
8201 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
8202 to allow for modules to overrule them and to reduce redefinition
8203 warnings [Jim Jagielski]
8205 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
8208 *) Making the hard-coded cross-module function call mime_find_ct() (from
8209 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
8210 checking is really called even for proxy requests except for URLs with
8211 HTTP schemes (because there we can optimize by not running the type
8212 checking hooks due to the fact that the proxy gets the MIME Content-type
8213 from the remote host later). This change cleans up mod_mime by removing
8214 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
8215 especially unbundles mod_proxy and mod_mime. This way they both now can
8216 be compiled as shared objects and are no longer tied together.
8217 [Ralf S. Engelschall]
8219 *) util.c cleanup and speedup. [Dean Gaudet]
8221 *) API: Clarification, pstrndup() will always copy n bytes of the source
8222 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
8224 *) Mark module command_rec and handler_rec structures const so that they
8225 end up in the read-only data section (and are friendlier to systems
8226 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
8228 *) Add check to the "Port" directive to make sure the specified
8229 port is in the appropriate range. [Ben Hyde]
8231 *) Performance improvements to invoke_handler().
8232 [Dmitry Khrustalev <dima@bog.msu.su>]
8234 *) Added support for building shared objects even for library-style modules
8235 (which are built from more than one object file). This now provides the
8236 ability to build mod_proxy as a shared object module. Additionally
8237 modules like mod_example are now also supported for shared object
8238 building because the generated Makefiles now no longer assume there is at
8239 least one statically linked module. [Ralf S. Engelschall]
8241 *) API: Clarify usage of content_type, handler, content_encoding,
8242 content_language and content_languages fields in request_rec. They
8243 must always be lowercased; and the strings pointed to shouldn't
8244 be modified (you must copy them to modify them). Fix a few bugs
8245 related to this. [Dean Gaudet]
8247 *) API: Clarification: except for RAW_ARGS, all command handlers can
8248 treat the char * parameters as permanent, and modifiable. There
8249 is no need to pstrdup() them. Clean up some needless pstrdup().
8252 *) Now mod_so keeps track of which module shared objects with which names
8253 are loaded and thus avoids multiple loading and unloading and irritating
8254 error_log messages. [Ralf S. Engelschall]
8256 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
8257 environment variable in the apache core. But that tweaking interferes
8258 with mod_setenv. So don't tweak if the user has specified an explicit
8259 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
8261 *) rputs() did not calculate r->sent_bodyct properly.
8262 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
8264 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
8265 name, or left unset if this value is unavailable. Apache was setting
8266 it to the IP address when unavailable.
8267 [Tony Finch <fanf@demon.net>] PR#1925
8269 *) Various improvements to the configuration and build support for compiling
8270 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
8271 OSF1 support with GCC and vendor compilers was added. This way shared
8272 object support is now provided out-of-the-box for FreeBSD, Linux,
8273 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
8274 [Ralf S. Engelschall]
8276 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
8277 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
8278 and USE_OS2_SCOREBOARD. [Dean Gaudet]
8280 *) Fix one more special locking problem for RewriteMap programs in
8281 mod_rewrite: According to the documentation of flock(), "Locks are on
8282 files, not file descriptors. That is, file descriptors duplicated
8283 through dup(2) or fork(2) do not result in multiple instances of a lock,
8284 but rather multiple references to a single lock. If a process holding a
8285 lock on a file forks and the child explicitly unlocks the file, the
8286 parent will lose its lock.". To overcome this we have to make sure the
8287 RewriteLock file is opened _AFTER_ the childs were spawned which is now
8288 the case by opening it in the child_init instead of the module_init API
8289 hook. [Ralf S. Engelschall] PR#1029
8291 *) Change to Location and LocationMatch semantics. LocationMatch no
8292 longer lets a single slash match multiple adjacent slashes in the
8293 URL. This change is for consistency with RewriteRule and
8294 AliasMatch. Multiple slashes have meaning in URLs that they do
8295 not have in (some) filesystems. Location on the other hand can
8296 be considered a shorthand for a more complicated regex, and it
8297 does match multiple slashes with a single slash -- which is
8298 also consistent with the Alias directive.
8299 [Dean Gaudet] related PR#1440
8301 *) Fix bug with mod_mime_magic causing certain files, including files
8302 of length 0, to result in no response from the server.
8305 *) The Configure script now generates src/include/ap_config.h which
8306 contains the set of defines used when Apache is compiled on a platform.
8307 This file can then be included by external modules before including
8308 any Apache header files in case they are being built separately from
8309 Apache. Along with this change, a couple of minor changes were
8310 made to make Apache's #defines coexist peacefully with any autoconf
8311 defines an external module might have. [Rasmus Lerdorf]
8313 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
8314 but without any RewriteXXXXX directives. Here mod_rewrite is given no
8315 chance by the API to initialize its per-server configuration and thus
8316 receives the wrong one from the main server. This is now avoided by
8317 remembering the server together with the config structure while
8318 configuring and later assuming there is no config when we see a
8319 difference between the remembered server and the one calling us.
8320 [Ralf S. Engelschall] PR#1790
8322 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
8323 is automatically disabled under configure time when the dbm_xxx functions
8324 are not available. Second, two heavy source code errors in the DBM
8325 support code were fixed. This makes DBM RewriteMap's usable again after
8326 a long time of brokenness. [Ralf S. Engelschall] PR#1696
8328 *) Now all configuration files support Unix-style line-continuation via
8329 the trailing backslash ("\") character. This enables us to write down
8330 complex or just very long directives in a more readable way. The
8331 backslash character has to be really the last character before the
8332 newline and it has not been prefixed by another (escaping) backslash.

8338 *) To deal with modules being compiled and [dynamically] linked
8339 at a different time from the core, the SERVER_VERSION and
8340 SERVER_BUILT symbols have been abstracted through the new
8341 API routines apapi_get_server_version() and apapi_get_server_built().
8344 *) WIN32: Preserve trailing slash in canonical path (and hence
8345 in PATH_INFO). [Paul Sutton, Ben Laurie]
8347 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
8348 depending on the rev of Solaris and what mixture of modules
8349 are in use. So it has been disabled, and Solaris is back to
8350 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
8351 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
8352 up static content only servers. Or it may fail unpredictably.
8353 [Dean Gaudet] PR#1779, 1854, 1904
8355 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
8358 *) API: Rewrite of absoluteURI handling, and in particular how
8359 absoluteURIs match vhosts. Unless a request is a proxy request, a
8360 "http://host" url is treated as if a similar "Host:" header had been
8361 supplied. This change was made to support future HTTP/1.x protocols
8362 which may require clients to send absoluteURIs for all requests.
8364 In order to achieve this change subtle changes were made to the API. In a
8365 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
8366 that the unmodified uri can be retrieved easily. r->proxyreq is not set
8367 by the core, modules must set it during the post_read_request or
8368 translate_names phase.
8370 Plus changes to the virtualhost test suite for absoluteURI testing.
8372 This fixes several bugs with the proxy proxying requests to vhosts
8373 managed by the same httpd.
8376 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
8377 code from mod_rewrite. The vhost matching is now performed by a
8378 globally available function matches_request_vhost(). [Dean Gaudet]
8380 *) Reduce memory usage, and speed up ServerAlias support. As a

8391 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
8392 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
8394 *) API: A new source module main/util_uri.c; It contains a routine
8395 parse_uri_components() and friends which breaks a URI into its component
8396 parts. These parts are stored in a uri_components structure called
8397 parsed_uri within each request_rec, and are available to all modules.
8398 Additionally, an unparse routine is supplied which re-assembles the URI
8399 components back to an URI, optionally hiding the username:password@ part
8400 from ftp proxy requests, and other useful routines. Within the structure,
8401 you find on a ready-for-use basis:
8402 scheme; /* scheme ("http"/"ftp"/...) */
8403 hostinfo; /* combined [user[:password]@]host[:port] */
8404 user; /* user name, as in http://user:passwd@host:port/ */
8405 password; /* password, as in http://user:passwd@host:port/ */
8406 hostname; /* hostname from URI (or from Host: header) */
8407 port_str; /* port string (integer representation is in "port") */
8408 path; /* the request path (or "/" if only scheme://host was given) */
8409 query; /* Everything after a '?' in the path, if present */
8410 fragment; /* Trailing "#fragment" string, if present */
8411 This is meant to serve as the platform for *BIG* savings in
8412 code complexity for the proxy module (and maybe the vhost logic).
8415 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
8416 ${map:key}) available for all location where a string is created in
8417 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
8418 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
8419 possible expansions are consequently usable at all string creation
8420 locations. [Ralf S. Engelschall]
8422 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
8423 and not 1) and the per-virtual-server merging of directives. Now all
8424 directives except `RewriteEngine' and `RewriteOption' are either
8425 completely overridden (default) or completely inherited (when
8426 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

8432 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause

8435 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
8436 (like SunOS and FreeBSD) which don't accept the locking of pipes
8437 directly. A new directive RewriteLock is introduced which can be used to
8438 setup a separate locking file which then is used for synchronization.

8453 *) The mod_setenvif BrowserMatch backwards compatibility command did not
8454 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
8456 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
8457 type but with a special post-processing for the looked-up value: It
8458 parses it into alternatives according to `|' chars and then only one
8459 particular alternative is chosen randomly (this is an essential
8460 functionality needed for balancing between backend-servers when using
8461 Apache as a Reverse Proxy. The looked up value here is a list of
8462 servers). Second, `int' with the built-in maps named `tolower' and
8463 `toupper' which can be used to map URL parts to a fixed case (this is an
8464 essential feature to fix the case of server names when doing mass
8465 virtual-hosting with the help of mod_rewrite instead of using
8466 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
8467 Jay Soffian <jay@cimedia.com>] PR#1631
8469 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
8470 This directive lets Apache adjust the URL in Location-headers on HTTP
8471 redirect responses sent by the remote server. This way the virtually
8472 mapped area is no longer left on redirects and thus by-passed which is
8473 especially essential when running Apache as a reverse proxy.

8626 other than kosher manner (e.g., the proxy including mod_mime.h).
8627 Module-private header files (the proxy, mod_mime, the regex library,
8628 and mod_rewrite) have not been moved to src/include; nor have
8629 the OS-abstraction files. [Ken Coar]
8631 *) Fix a bug where r->hostname didn't have the :port stripped
8632 from it. [Dean Gaudet]
8634 *) Tweaked the headers_out table size, and the subprocess_env
8635 table size guess in rename_original_environment(). Added
8636 MAKE_TABLE_PROFILE which can help discover make_table()
8637 calls that use too small an initial guess, see alloc.c.
8640 *) Options and AllowOverride weren't properly merging in the main
8641 server setting inside vhosts (only an issue when you have no
8642 <Directory> or other section containing an Options that affects
8643 a request). Options +foo or -foo in the main_server wouldn't
8644 affect the main_server's lookup defaults. [Dean Gaudet]
8646 *) Variable 'cwd' was being used pointlessly before being set.
8649 *) r->allowed handling cleaned up in the standard modules.
8652 *) Some case-sensitivity issues cleaned up to be consistent with
8653 RFC2068. [Dean Gaudet]
8655 *) SIGURG doesn't exist everywhere.
8656 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8658 *) mod_unique_id was erroneously generating a second unique id when
8659 an internal redirect occured. Such redirects occur, for example,
8660 when processing a DirectoryIndex match. [Dean Gaudet]
8662 *) API: table_add, table_merge, and table_set include implicit pstrdup()
8663 of the key and value. But in many cases this is not required
8664 because the key/value is a constant, or the value has been built
8665 by pstrcat() or other similar means. New routines table_addn,
8666 table_mergen, and table_setn have been added to the API, these
8667 routines do not pstrdup() their arguments. The core code and
8668 standard modules were changed to take advantage of these routines.
8669 The resulting server is up to 20% faster in some situations.
8671 Note that it is easy to get code subtly wrong if you pass a key/value
8672 which is in a pool other than the pool of the table. The only
8673 safe thing to do is to pass key/values which are in the pool of
8674 the table, or in one of the ancestors of the pool of the table.
8675 i.e. if the table is part of a subrequest, a value from the main
8676 request's pool is OK since the subrequest pool is a sub_pool of the
8677 main request's pool (and therefore has a lifespan at most as long as
8678 the main pool). There is debugging code which can detect improper
8679 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
8680 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
8682 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
8683 which don't exist on disk more gracefully; handles vhosts properly.
8684 Update documentation to reflect the code -- if there's no
8685 MimeMagicFile directive then the module is not enabled.
8688 *) PORT: Some older *nix dialects cannot automatically start scripts
8689 which begin with a #! interpreter line (the shell starts the scripts
8690 appropriately on these platforms). Apache now supports starting of
8691 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
8692 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
8695 *) API: "typedef array_header table" removed from alloc.h, folks should
8696 have been writing to use table as if it were an opaque type, but even
8697 some standard modules got this wrong. By changing the definition
8698 to "typedef struct table table" module authors will receive compile
8699 time warnings that they're doing the wrong thing. This change
8700 facilitates future changes with more sophisticated table
8701 structures. Specifically, module authors should be using table_elts()
8702 to get access to an array_header * for the table. [Dean Gaudet]
8704 *) API: Renamed new_connection() to avoid namespace collision with LDAP
8705 library routines. [Ken Coar, Rasmus Lerdorf]
8707 *) WIN32: mod_speling is now available on the Win32 platform.
8710 *) For clarity the following compile time definition was changed:
8712 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
8714 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
8715 and not be a general notice that the OS has mmap(). Now the
8716 HAVE_MMAP/SHMGET #defines strictly are informational that the
8717 OS has that method of shared memory; the type to use for
8718 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
8719 and USE_SHMGET_SCOREBOARD). This allows outside modules to
8720 determine if shared memory is available and allows Apache
8721 to determine the best method to use for the scoreboard.
8724 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
8725 as do various earlier versions. It should be safe on all versions.
8726 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
8727 the slack code. A few other cleanups for Unixware.

8736 authenticated. [Roy Fielding] PR#1399

8747 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
8749 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
8750 The choice of flock vs. fcntl was made based on timings which showed that
8751 even on non-NFS, non-exported filesystems fcntl() was an order of
8752 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
8753 that single socket users will see no difference. [Dean Gaudet] PR#467
8755 *) "File does not exist" error message was erroneously including the
8756 errno. [Marc Slemko]
8758 *) Improve the warning message generated when a client drops the
8759 connection (hits stop button, etc.) during a send. [Roy Fielding]
8761 *) Defining GPROF will disable profiling in the parent and enable it
8762 in the children. If you're profiling under Linux this is pretty much
8763 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
8765 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
8768 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
8769 gcc functionality. Work around it.

8776 purposes caused some compilers heartburn without adding any

8779 *) The src/main/*.h header files have had #ifndef wrappers added to
8780 insulate them against duplicate calls if they get included through
8781 multiple paths (e.g., in .c files as well as other .h files).
8784 *) The libap routines now have a header file for their prototypes,
8785 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
8787 *) mod_autoindex with a plaintext header file would emit the <PRE>
8788 start-tag before the HTML preamble, rather than after the preamble
8789 but before the header file contents. [John Van Essen <jve@gamers.org>]
8792 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8793 only an issue on systems without a MAXDNAME define or where
8794 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8796 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8797 is used to read various types of files such as htaccess and

8801 properly null terminated. [Marc Slemko]
8803 *) The "Connection" header could be sent back with multiple "close"
8804 tokens. Not an error, but a waste.

8807 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
8808 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
8810 *) "basic" auth needs a case-insensitive comparison.
8811 [Ronald.Tschalaer@psi.ch] PR#1666
8813 *) For maximum portability, the environment passed to CGIs should
8814 only contain variables whose names match the regex
8815 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
8816 underscores over any character outside the regex. This
8817 affects HTTP_* variables, in a way that should be backward
8818 compatible for all the standard headers; and affects variables
8819 set with SetEnv/BrowserMatch and similar directives.

8916 doing a writev() to assemble multiple buffers in one system
8917 call. This is critical for modules such as mod_include,
8918 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
8919 strings in some cases. The result would be extra effort
8920 setting up writev(), and in many cases extra effort building

9062 is the same for both per-server and per-directory context with only a
9063 minimum difference (the prefix stripping in per-dir context). As a
9064 side-effect some subtle restrictions and two recently discovered problems

9157 *) PORT: "Fix" PR#467 by generating warnings on systems which we have
9158 not been able to get working USE_*_SERIALIZED_ACCEPT settings for.
9159 Document this a bit more in src/PORTING. [Dean Gaudet] PR#467
9161 *) Ensure that one copy of config warnings makes it to the
9162 error_log. [Dean Gaudet]
9164 *) Invent new structure and associated methods to handle config file
9165 reading. Add "custom" hook to use config file cfg_getline() on
9166 something which is not a FILE* [Martin Kraemer]

9191 __NetBSD__. Workaround by defining NETBSD.
9192 [Chris Craft <ccraft@cncc.cc.co.us>] PR#977
9194 *) PORT: UnixWare 2.x requires -lgen for syslog.
9195 [Hans Snijder <hs@meganet.nl>] PR#1249
9197 *) PORT: ULTRIX appears to not have syslog.
9198 [Lars Eilebrecht <Lars.Eilebrecht@unix-ag.org>]
9200 *) PORT: Basic Gemini port (treat it like unixware212).
9201 ["Pavel Yakovlev (Paul McHacker)" <hac@tomcat.olly.ru>]
9203 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
9204 use USE_SHMGET_SCOREBOARD.
9207 *) Various improvements in detecting config file errors (missing closing
9208 directives for <Directory>, <Files> etc. blocks, prohibiting global
9209 server settings in <VirtualHost> blocks, flagging unhandled multiple
9210 arguments to <Directory>, <Files> etc.)
9213 *) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
9214 variable to provide this one to suexec'd CGIs, too.
9215 [M.D.Parker <mdpc@netcom.com>] PR#1284
9217 *) New support tool: src/support/split-logfile, a sample Perl script which
9218 splits up a combined access log into separate files based on the
9219 name of the virtual host (listed first in the log records by "%v").
9222 Changes with Apache 1.3b2 (there is no 1.3b1)
9224 *) TestCompile was not passing $LIBS [Dean Gaudet]
9226 *) Makefile.tmpl was not using $CFLAGS in the link phase.
9229 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
9230 rudimentary memory debugger which can be used on live servers with
9231 low impact -- it sets all allocated and freed memory bytes to 0xa5.
9232 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
9233 and free() for each object. This is far more expensive and should
9234 only be used for testing with tools such as Electric Fence and
9235 Purify. See main/alloc.c for more details. [Dean Gaudet]
9237 *) Configure uses a sh trap and didn't set its exitcode properly.
9238 [Dean Gaudet] PR#1159
9240 *) Yet another vhost revamp. Add the NameVirtualHost directive which
9241 explicitly lists the ip:port pairs that are to be used for name-vhosts.
9242 From a given ip:port, regardless what the Host: header is, you can
9243 only reach the vhosts defined on that ip:port. The precedence of
9244 vhosts was reversed to match other precedences in the config --
9245 the earlier vhosts override the later vhosts. All vhost matching was
9246 moved into http_vhost.[ch]. [Dean Gaudet]
9248 *) ap_inline can be used to force inlining. GNUC __attribute__() can
9249 be used for whatever reason is appropriate (i.e. format() warnings
9250 for printf style functions). Both are enabled only with
9251 gcc >= 2.7.x (so that we have fewer support issues with older
9252 versions). [Dean Gaudet]
9254 *) Fix support for Proxy Authentication (we were testing the response
9255 status too early). [Marc Slemko]
9257 *) CoreDumpDirectory directive directs where the core file is
9258 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
9259 received. [Marc Slemko, Dean Gaudet]
9261 *) PORT: Support for Atari MINT.
9262 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
9264 *) When booting, apache will now detach itself from stdin, stdout,
9265 and stderr. stderr will not be detached until after the config
9266 files have been read so you will be able to see initial error
9267 messages. After that all errors are logged in the error_log.
9268 This makes it more convenient to start apache via rsh, ssh,
9269 or crontabs. [Dean Gaudet] PR#523
9271 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
9272 Also removed the auto-generated link to www.apache.org that was the
9273 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
9275 *) send_fb would not detect aborted connections in some situations.
9278 *) mod_include would use uninitialized data when parsing certain
9279 expressions involving && and ||. [Brian Slesinsky] PR#1139
9281 *) mod_imap should only handle GET methods. [Jay Bloodworth]
9283 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
9285 *) mod_autoindex improperly counted &escapes; as more than one
9286 character in the description. It also improperly truncated
9287 descriptions that were exactly the maximum length.
9290 *) RedirectMatch was not properly escaping the result (PR#1155). Also
9291 "RedirectMatch /advertiser/(.*) $1" is now permitted.
9294 *) mod_include now uses symbolic names to check for request success
9295 and return HTTP errors, and correctly handles all types of
9296 redirections (previously it only did temporary redirect correctly).
9297 [Ken Coar, Roy Fielding]
9299 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
9300 r->filename. Since those two are meant to be in sync with each other
9301 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
9303 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
9304 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
9306 *) Inetd mode (which is buggy) uses timeouts without having setup the
9307 jmpbuffer. [Dean Gaudet] PR#1064
9309 *) Work around problem under Linux where a child will start looping
9310 reporting a select error over and over.
9311 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
9313 *) Fixed error in proxy_util.c when looping through multiple host IP
9314 addresses. [Lars Eilebrecht] PR#974
9316 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
9317 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
9318 bytes before writing, but it will never split a log entry across a
9319 buffer boundary. [Dean Gaudet]
9321 *) API: the short_score record has been split into two pieces, one which
9322 the parent writes on, and one which the child writes on. As part of
9323 this change the get_scoreboard_info() function was removed, and
9324 scoreboard_image was exported. This change fixes a race condition
9325 in file based scoreboard systems, and speeds up changes involving the
9326 scoreboard in earlier 1.3 development. [Dean Gaudet]
9328 *) API: New register_other_child() API (see http_main.h) which allows
9329 modules to register children with the parent for maintenance. It
9330 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
9332 *) API: New piped_log API (see http_log.h) which implements piped logs,
9333 and will use register_other_child to implement reliable piped logs
9334 when it is available. The reliable piped logs part can be disabled
9335 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
9336 logs is only available on Unix. [Dean Gaudet]
9338 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
9339 meets_conditions(). This allows conditional HTTP selection to be
9340 handled separately from the storing of the header fields, and provides
9341 the ability for CGIs to set their own ETags for conditional checking.
9342 [Ken Coar, Roy Fielding] PR#895
9344 *) Changes to mod_log_config to allow naming of format strings.
9345 Format nicknames are defined with "LogFormat fmt nickname", and can
9346 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
9349 *) New module, "mod_speling", which can help find files even when
9350 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
9352 *) API: New function child_terminate() triggers the child process to
9353 exit, while allowing the child finish what it needs to for the
9354 current request first.
9355 [Doug MacEachern, Alexei Kosut]
9357 *) Windows now defaults to using full status reports with mod_status.
9358 [Alexei Kosut] PR #1094
9360 *) *Really* disable all mod_rewrite operations if the engine is off.
9361 Some things (like RewriteMaps) were checked/performed even if they
9362 weren't supposed to be. [Ken Coar] PR #991
9364 *) Implement a new timer scheme which eliminates the need to call alarm() all
9365 the time. Instead a counter in the scoreboard for each child is used to
9366 show when the child has made forward progress. The parent samples this
9367 counter every scoreboard maintenance cycle, and issues SIGALRM if no
9368 progress has been made in the timeout period. This reduces the static
9369 request best-case syscall count to 22 from 29. This scheme is only
9370 used by systems with memory-based scoreboards. [Dean Gaudet]
9372 *) The proxy now properly handles CONNECT requests which are sent
9373 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
9375 *) A script called apachectl has been added to the support
9376 directory. This script allows you to do things such as
9377 "apachectl start" and "apachectl restart" from the command
9380 *) Modules and core routines are now put into libraries, which
9381 simplifies the link line tremendously (among other advantages).
9384 *) Some of the MD5 names defined in Apache have been renamed to have
9385 an `ap_' prefix to avoid conflicts with routines supplied by
9386 external libraries. [Ken Coar]
9388 *) Removal of mod_auth_msql.c from the distribution. There are many
9389 other options for databases today. Rather than offer one option,
9390 offer none at this time. mod_auth_msql and other SQL database
9391 authentication modules can be found at the Apache Module Registry.
9392 http://modules.apache.org/ It would be nice to offer a generic
9393 mod_auth_sql option in the near future.
9395 *) PORT: BeOS support added [Alexei Kosut]
9397 *) Configure no longer accepts the -make option, since it creates
9398 Makefile on the fly based on Makefile.tmpl and Configuration.
9400 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
9401 of forcibly killing off all its processes and exiting without
9402 cleaning up. [Alexei Kosut]
9404 *) API: A new field in the request_rec, r->mtime, has been added to
9405 avoid gratuitous parsing of date strings. It is intended to hold
9406 the last-modified date of the resource (if applicable). An
9407 update_mtime() routine has also been added to advance it if
9408 appropriate. [Roy Fielding, Ken Coar]
9410 *) SECURITY: If a htaccess file can not be read due to bad permissions,
9411 deny access to the directory with a HTTP_FORBIDDEN. The previous
9412 behavior was to ignore the htaccess file if it could not be read.
9413 This change may make some setups with unreadable htaccess files
9414 stop working. [Marc Slemko] PR#817
9416 *) Add aplog_error() providing a mechanism to define levels of
9417 verbosity to the server error logging. This addition also provides
9418 the ability to log errors using syslogd. Error logging is configurable
9419 on a per-server basis using the LogLevel directive. Conversion
9420 of log_*() in progress. [Randy Terbush]
9422 *) Further enhance aplog_error() to not log filename, line number, and
9423 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
9425 *) WIN32: Canonicalise filenames under Win32. Short filenames are
9426 converted to long ones. Backslashes are converted to forward
9427 slashes. Case is converted to lower. Parts of URLs that do not
9428 correspond to files are left completely alone. [Ben Laurie]
9430 *) PORT: 2 new OSs added to the list of ports:
9431 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
9432 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
9434 *) Add the server version (SERVER_VERSION macro) to the "server
9435 configured and running" entry in the error_log. Also build an
9436 object file at link-time that contains the current time
9437 (SERVER_BUILT global const char[]), and include that in the
9440 *) Set r->headers_out when sending responses from the proxy.
9441 This fixes things such as the logging of headers sent from
9442 the proxy. [Marc Slemko] PR#659
9444 *) support/httpd_monitor is no longer distributed because the
9445 scoreboard should not be file based if at all possible. Use
9446 mod_status to see current server snapshot.
9448 *) (set_file_slot): New function, allowing auth directives to be
9449 independent of the server root, so the server documents can be
9450 moved to a different directory or machine more easily.
9451 [David J. MacKenzie]
9453 *) If no TransferLog is given explicitly, decline
9454 to log. This supports coexistence with other logging modules,
9455 such as the custom one that UUNET uses. [David J. MacKenzie]
9457 *) Check for titles in server-parsed HTML files.
9458 Ignore leading newlines and returns in titles. The old behavior
9459 of replacing a newline after <title> with a space causes the
9460 title to be misaligned in the listing. [David J. MacKenzie]
9462 *) Change mod_cern_meta to be configurable on a per-directory basis.
9463 [David J. MacKenzie]
9465 *) Add 'Include' directive to allow inclusion of configuration
9466 files within configuration files. [Randy Terbush]
9468 *) Proxy errors on connect() are logged to the error_log (nothing
9469 new); now they include the IP address and port that failed
9470 (*that's* new). [Ken Coar, Marc Slemko] PR#352
9472 *) Various architectures now define USE_MMAP_FILES which causes
9473 the server to use mmap() for static files. There are two
9474 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
9475 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
9476 number of bytes written in one cycle from a single mmap()d object,
9477 default 32768). [Dean Gaudet]
9479 *) API: Added post_read_request API phase which is run right after reading
9480 the request from a client, or right after an internal redirect. It is
9481 useful for modules setting environment variables that depend only on
9482 the headers/contents of the request. It does not run during subrequests
9483 because subrequests inherit pretty much everything from the main
9484 request. [Dean Gaudet]
9486 *) Added mod_unique_id which is used to generate a unique identifier for
9487 each hit, available in the environment variable UNIQUE_ID.
9490 *) init_modules is now called after the error logs have been opened. This
9491 allows modules to emit information messages into the error logs.
9494 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
9495 information for case where proxy module is not available. [Marc Slemko]
9497 *) PORT: Apache has need for mutexes to serialize its children around
9498 accept. In prior versions either fcntl file locking or flock file
9499 locking were used. The method is chosen by the definition of
9500 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
9501 and FLOCK for flock(). New options have been added:
9502 - SYSVSEM to use System V style semaphores
9503 - PTHREAD to use POSIX threads (appears to work on Solaris only)
9504 - USLOCK to use IRIX uslock
9505 Based on timing various techniques, the following changes were made
9507 - Linux 2.x uses flock instead of fcntl
9508 - Solaris 2.x uses pthreads
9509 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
9510 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
9511 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
9512 Martijn Koster <m.koster@pobox.com>]
9514 *) PORT: The semantics of accept/select make it very desirable to use
9515 mutexes to serialize accept when multiple Listens are in use. But
9516 in the case where only a single socket is open it is sometimes
9517 redundant to serialize accept(). Not all unixes do a good job with
9518 potentially dozens of children blocked on accept() on the same
9519 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
9520 the server will avoid serialization when listening on only one socket,
9521 and use serialization when listening on multiple sockets.
9522 [Dean Gaudet] PR#467
9524 *) Configure changes: TestLib replaced by TestCompile, which has
9525 some additional capability (such as doing a sanity check of
9526 the compiler and flags selected); the version of Solaris is now
9527 available via the #define value of SOLARIS2; IRIX n32bit libs
9528 now supported and selectable by new Configuration Rule: IRIXN32;
9529 We no longer default to -O2 optimization. [Jim Jagielski]
9531 *) Updated Configure: Configuration now uses AddModule to specify
9532 module source or binary file location, relative to src directory.
9533 Modules can be dropped into modules/extra, or in their own
9534 directory, and modules can come with a Makefile or Configure can
9535 create one. Modules can add compiler or library information to
9536 generated Makefiles. [Paul Sutton]
9538 *) Source core re-organisation: distributed modules are now in
9539 modules/standard. All other source code is in main. OS-specific
9540 code is in os/{unix,emx,win32} directories. [Paul Sutton]
9542 *) mod_browser has been removed, since it's replaced by mod_setenvif.
9545 *) Fix another long-standing bug in sub_req_lookup_file where it would
9546 happily skip past access checks on subdirectories looked up with
9547 relative paths. (It's used by mod_dir, mod_negotiation,
9548 and mod_include.) [Dean Gaudet]
9550 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
9551 N is the number of <Directory> sections, and M is the number of
9552 components in the filename of an object.
9554 To achieve this optimization the following config changes were made:
9555 - Wildcards (* and ?, not the regex forms) in <Directory>s,
9556 <Files>s, and <Location>s now treat a slash as a special
9557 character. For example "/home/*/public_html" previously would
9558 match "/home/a/andrew/public_html", now it only matches things
9559 like "/home/bob/public_html". This mimics /bin/sh behaviour.
9560 - It's possible now to use [] wildcarding in <Directory>, <Files>
9562 - Regex <Directory>s are applied after all non-regex <Directory>s.
9566 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
9567 and corrupted paths. [Dean Gaudet]
9569 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
9570 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
9571 be accessed now via backreferences $1..$9 in RewriteConds test-against
9572 strings in addition to RewriteRules subst string. Second the grouped
9573 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
9574 via backreferences %1..%9 both in following RewriteCond test-against
9575 strings and RewriteRules subst string. This provides maximum flexibility
9576 through the use of backreferences.
9577 Additionally the rewriting engine was cleaned up by putting common
9578 code to the new expand_backrefs_inbuffer() function.
9579 [Ralf S. Engelschall]
9581 *) When merging the main server's <Directory> and <Location> sections into
9582 a vhost, put the main server's first and the vhost's second. Otherwise
9583 the vhost can't override the main server. [Dean Gaudet] PR#717
9585 *) The <Directory> code would merge and re-merge the same section after
9586 a match was found, possibly causing problems with some modules.
9589 *) ip-based vhosts are stored and queried using a hashing function, which
9590 has been shown to improve performance on servers with many ip-vhosts.
9591 Some other changes had to be made to accommodate this:
9592 - the * address for vhosts now behaves like _default_
9593 - the matching process now is:
9594 - match an ip-vhost directly via hash (possibly matches main
9596 - if that fails, just pretend it matched the main server
9597 - if so far only the main server has been matched, perform
9598 name-based lookups (ServerName, ServerAlias, ServerPath)
9599 *only on name-based vhosts*
9600 - if they fail, look for _default_ vhosts
9601 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
9603 *) dbmmanage overhaul:
9604 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
9605 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
9606 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
9607 - provide better seed for rand
9608 - prompt for password as per getpass(3) (turn off echo, read from
9610 - use "newstyle" crypt based on $Config{osname} ($^O)
9611 - will not add a user if already in database, use new `update' command
9613 - added `check' command to check a users' password
9614 - added `import' command to convert existing password text-files or
9615 dbm files exported with `view'
9616 - more descriptive usage, general cleanup, 'use strict' clean, etc.
9619 *) Added psocket() which is a pool form of socket(), various places within
9620 the proxy weren't properly blocking alarms while registering the cleanup
9621 for its sockets. bclose() now uses pclose() and pclosesocket(). There
9622 was a bug where the client socket was being close()d twice due a still
9623 registered cleanup. [Dean Gaudet]
9625 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
9628 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
9629 [Jason Venner <jason@idiom.com>] PR#667
9631 *) Enable ``=""'' for RewriteCond directives to match against
9632 the empty string. This is the preferred way instead of ``^$''.
9633 [Ralf S. Engelschall]
9635 *) Fixed an infinite loop in mod_imap for references above the server root
9636 [Dean Gaudet] PR#748
9638 *) mod_proxy now has a ReceiveBufferSize directive, similar to
9639 SendBufferSize, so that the TCP window can be set appropriately
9640 for LFNs. [Phillip A. Prindeville]
9642 *) mod_browser has been replaced by the more general mod_setenvif
9643 (courtesy of Paul Sutton). BrowserMatch* directives are still
9644 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
9645 UnSetEnvIfZero directives. [Ken Coar]
9647 *) "HostnameLookups double" forces double-reverse DNS to succeed in
9648 order for remote_host to be set (for logging, or for the env var
9649 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
9652 *) mod_access overhaul:
9653 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
9654 and cidr syntax (i.e. 10.1.0.0/16). PR#762
9655 - Critical path was sped up by pre-computing a few things at config time.
9656 - The undocumented syntax "allow user-agents" was removed,
9657 the replacement is "allow from env=foobar" combined with mod_browser.
9658 - When used with hostnames it now forces a double-reverse lookup
9659 no matter what the directory settings are. This double-reverse
9660 doesn't affect any of the other routines that use the remote
9661 hostname. In particular it's still passed to CGIs and the log
9662 without the double-reverse check. Related PR#860.
9665 *) When a large bwrite() occurs (larger than the internal buffer size),
9666 while there is already something in the buffer, apache will combine
9667 the large write and the buffer into a single writev(). (This is
9668 in anticipation of using mmap() for reading files.)
9671 *) In obscure cases where a partial socket write occurred while chunking,
9672 Apache would omit the chunk header/footer on the next block. Cleaned
9673 up other bugs/inconsistencies in error conditions in buff.c. Fixed
9674 a bug where a long pause in DNS lookups could cause the last packet
9675 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
9677 *) API: Added child_exit function to module structure. This is called
9678 once per "heavy-weight process" just before a server child exit()'s
9679 e.g. when max_requests_per_child is reached, etc.
9680 [Doug MacEachern, Dean Gaudet]
9682 *) mod_include cleanup showed that handle_else was being used to handle
9683 endif. It didn't cause problems, but it was cleaned up too.
9686 *) mod_cern_meta would attempt to find meta files for the directory itself
9687 in some cases, but not in others. It now avoids it in all cases.
9690 *) mod_mime_magic would core dump if there was a decompression error.
9691 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
9693 *) PORT: some variants of DGUX require -lsocket -lnsl
9694 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
9696 *) mod_autoindex now allows sorting of FancyIndexed directory listings
9697 by the various fields (name, size, et cetera), either in ascending
9698 or descending order. Just click on the column header. [Ken Coar]
9700 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
9701 CPUs like the Alpha. Apache still stores ints in pointers, but that's
9702 the relatively safe direction. [Dean Gaudet] PR#344
9704 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
9705 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
9707 *) child_main avoids an unneeded call to select() when there is only one
9708 listening socket. [Dean Gaudet]
9710 *) In the event that the server is starved for idle servers it will
9711 spawn 1, then 2, then 4, ..., then 32 servers each second,
9712 doubling each second. It'll also give a warning in the errorlog
9713 since the most common reason for this is a poor StartServers
9714 setting. The define MAX_SPAWN_RATE can be used to raise/lower
9715 the maximum. [Dean Gaudet]
9717 *) Apache now provides an effectively unbuffered connection for
9718 CGI scripts. This means that data will be sent to the client
9719 as soon as the CGI pauses or stops output; previously, Apache would
9720 buffer the output up to a fixed buffer size before sending, which
9721 could result in the user viewing an empty page until the CGI finished
9722 or output a complete buffer. It is no longer necessary to use an
9723 "nph-" CGI to get unbuffered output. Given that most CGIs are written
9724 in a language that by default does buffering (e.g. perl) this
9725 shouldn't have a detrimental effect on performance.
9727 "nph-" CGIs, which formerly provided a direct socket to the client
9728 without any server post-processing, were not fully compatible with
9729 HTTP/1.1 or SSL support. As such they would have had to implement
9730 the transport details, such as encryption or chunking, in order
9731 to work properly in certain situations. Now, the only difference
9732 between nph and non-nph scripts is "non-parsed headers".
9733 [Dean Gaudet, Sameer Parekh, Roy Fielding]
9735 *) If a BUFF is switched from buffered to unbuffered reading the first
9736 bread() will return whatever remained in the buffer prior to the
9737 switch. [Dean Gaudet]
9739 Changes with Apache 1.3a1
9741 *) Added another Configure helper script: TestLib. It determines
9742 if a specified library exists. [Jim Jagielski]
9744 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
9745 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
9748 *) PORT: Some architectures use size_t for various lengths in network
9749 functions such as accept(), and getsockname(). The definition
9750 NET_SIZE_T is used to control this. [Dean Gaudet]
9752 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
9753 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
9754 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
9756 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
9757 [Igor N Kovalenko <infoh@mail.wplus.net>]
9759 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
9760 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
9761 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
9762 [Dean Gaudet] related PR#875
9764 *) API: Correct child_init() slot declaration from int to void, to
9765 match the init() declaration. Update mod_example to use the new
9768 *) added transport handle slot (t_handle) to the BUFF structure
9771 *) get_client_block() returns wrong length if policy is
9772 REQUEST_CHUNKED_DECHUNK.
9773 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
9775 *) Support the image map format of FrontPage. For example:
9776 rect /url.hrm 10 20 30 40
9777 ["Chris O'Byrne" <obyrne@iol.ie>] PR#807
9779 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
9780 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
9782 *) AddModuleInfo directive for mod_info which allows you to annotate
9783 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
9785 *) Added NoProxy directive to avoid using ProxyRemote for selected
9786 addresses. Added ProxyDomain directive to cause unqualified
9787 names to be qualified by redirection.
9788 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
9790 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
9791 header to the remote host in the proxy. [Sameer Parekh and
9794 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
9795 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
9796 URLs, fixed rewritelog(), fixed forced response code handling on
9797 redirects from within .htaccess files, disabled pipe locking under
9798 braindead SunOS 4.1.x, allow env variables to be set even on rules with
9799 no substitution, bugfixed situations where HostnameLookups is off, made
9800 mod_rewrite more thread-safe for NT port and fixed problem when creating
9801 an empty query string via "xxx?".
9802 This update also removes the copyright of Ralf S. Engelschall,
9803 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
9804 exclusively copyrighted by the Apache Group now. This happened because
9805 the author now has gifted mod_rewrite exclusively to the Apache Group and
9806 no longer maintains an external version.
9807 [Ralf S. Engelschall]
9809 *) API: Added child_init function to module structure. This is called
9810 once per "heavy-weight process" before any requests are handled.
9811 See http_config.h for more details. [Dean Gaudet]
9813 *) Anonymous_LogEmail was logging on each subrequest.
9814 [Dean Gaudet] PR#421, 868
9816 *) API: Added is_initial_req() which tests if the request being
9817 processed is the initial request, or a subrequest.
9820 *) Extended SSI (mod_include) now handles additional relops for
9821 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
9823 *) Configure fixed to correctly propagate user-selected options and
9824 settings (such as CC and OPTIM) to Makefiles other than
9825 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
9827 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
9828 directory indices to start with the contents of the HeaderName file
9829 if there is one. If there isn't one, the behaviour is unchanged.
9830 [Ken Coar, Roy Fielding, Andrey A. Chernov]
9832 *) WIN32: Modules can now be dynamically loaded DLLs using the
9833 LoadModule/LoadFile directives. Note that module DLLs must be
9834 compiled with the multithreaded DLL version of the runtime library.
9835 [Alexei Kosut and Ben Laurie]
9837 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
9838 This allows the admin to completely remove automatic indexing
9839 from the server, while still supporting the basic functions of
9840 trailing-slash redirects and DirectoryIndex files. Note that if
9841 you're carrying over an old Configuration file and you use directory
9842 indexing then you'll want to add:
9844 Module autoindex_module mod_autoindex.o
9846 before mod_dir in your Configuration. [Dean Gaudet]
9848 *) popendir/pclosedir created to properly protect directory scanning.
9849 [Dean Gaudet] PR#525
9851 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
9852 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
9853 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
9856 *) The AccessFileName directive can now take more than one filename.
9857 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
9859 *) The new mod_mime_magic can be used to "magically" determine the type
9860 of a file if the extension is unknown. Based on the unix file(1)
9861 command. [Ian Kluft <ikluft@cisco.com>]
9863 *) We now determine and display the time spent processing a
9864 request if desired. [Jim Jagielski]
9866 *) mod_status: PID field of "dead" child slots no longer displays
9867 main httpd process's PID. [Jim Jagielski]
9869 *) Makefile.nt added - to build all the bits from the command line:
9870 nmake -f Makefile.nt
9871 Doesn't yet work properly. [Ben Laurie]
9873 *) Default text of 404 error is now "Not Found" rather than the
9874 potentially misleading "File Not Found". [Ken Coar]
9876 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
9877 for the net if we require people that actually need this data to
9878 enable it. [Linus Torvalds]
9880 *) directory_walk() is an expensive function, keep a little more state to
9881 avoid needless string counting. Add two new functions make_dirstr_parent
9882 and make_dirstr_prefix which replace all existing uses of make_dirstr.
9883 The new functions are a little less general than make_dirstr, but
9884 work more efficiently (less memory, less string counting).
9887 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
9888 to LDFLAGS) to avoid complications with lex rules in make files.
9889 [Dean Gaudet] PR#372
9891 *) run_method optimized to avoid needless scanning over NULLs in the
9892 module list. [Dean Gaudet]
9894 *) Revamp of (unix) scoreboard management code such that it avoids
9895 unnecessary traversals of the scoreboard on each hit. This is
9896 particularly important for high volume sites with a large
9897 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
9898 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
9899 httpd.h. [Dean Gaudet]
9901 *) In configurations using multiple Listen statements it was possible for
9902 busy sockets to starve other sockets of service. [Dean Gaudet]
9904 *) Added hook so standalone_main can be replaced at compile time
9905 (define STANDALONE_MAIN)
9908 *) Lowest-level read/write functions in buff.c will be replaced with
9909 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
9910 compile time. The default sfio discipline will behave as apache
9911 would without sfio compiled in.
9914 *) Enhance UserDir directive (mod_userdir) to accept a list of
9915 usernames for the 'disable' keyword, and add 'enable user...' to
9916 selectively *en*able userdirs if they're globally disabled.
9919 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
9920 will work with Netscape dbm files. (dbmmanage will probably not
9921 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
9923 *) Add a ListenBacklog directive to control the backlog parameter
9924 passed to listen(). Also change the default to 511 from 512.
9927 *) API: A new handler response DONE which informs apache that the
9928 request has been handled and it can finish off quickly, similar to
9929 how it handles errors. [Rob Hartill]
9931 *) Turn off chunked encoding after sending terminating chunk/footer
9932 so that we can't do it twice by accident. [Roy Fielding]
9934 *) mod_expire also issues Cache-Control: max-age headers.
9937 *) API: Added kill_only_once option for free_proc_chain so that it won't
9938 aggressively try to kill off specific children. For fastcgi.
9939 [Stanley Gambarin <gambarin@OpenMarket.com>]
9941 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
9943 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
9944 When used together, these cause mod_dir to emit HEIGHT and WIDTH
9945 attributes in the FancyIndexing IMG tags. [Ken Coar]
9947 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
9949 *) PORT: Added Windows NT support
9950 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
9952 Changes with Apache 1.2.6
9954 *) mod_include when using XBitHack Full would send ETags in addition to
9955 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
9956 [Dean Gaudet] PR#1133
9958 *) SECURITY: When a client connects to a particular port/addr, and
9959 gives a Host: header ensure that the virtual host requested can
9960 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
9962 *) Support virtual hosts with wildcard port and/or multiple ports
9963 properly. [Ed Korthof <ed@organic.com>]
9965 *) Fixed some case-sensitivity issues according to RFC2068.
9968 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
9969 and mod_include.c. [Dean Gaudet]
9971 *) Variable 'cwd' was being used pointlessly before being set.
9974 *) SIGURG doesn't exist on all platforms.
9975 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
9977 *) When an error occurs during a POST, or other operation with a
9978 request body, the body has to be read from the net before allowing
9979 a keepalive session to continue. [Roy Fielding] PR#1399
9981 *) When an error occurs in fcntl() locking suggest the user look up
9982 the docs for LockFile. [Dean Gaudet]
9984 *) table_set() and table_unset() did not deal correctly with
9985 multiple occurrences of the same key. [Stephen Scheck
9986 <sscheck@infonex.net>, Ben Laurie] PR#1604
9988 *) send_fd_length() did not calculate total_bytes_sent properly in error
9989 cases. [Ben Reser <breser@regnow.com>] PR#1366
9991 *) r->connection->user was allocated in the wrong pool causing corruption
9992 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
9994 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
9995 Also removed the auto-generated link to www.apache.org that was the
9996 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
9998 *) Multiple "close" tokens may have been set in the "Connection"
9999 header, not an error, but a waste.
10000 [Ronald.Tschalaer@psi.ch] PR#1683
10002 *) "basic" and "digest" auth tokens should be tested case-insensitive.
10003 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
10005 *) It appears the "257th byte" bug (see
10006 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
10007 at the 256th byte as well. Fixed. [Dean Gaudet]
10009 *) mod_rewrite would not handle %3f properly in some situations.
10012 *) Apache could generate improperly chunked HTTP/1.1 responses when
10013 the bputc() or rputc() functions were used by modules (such as
10014 mod_include). [Dean Gaudet]
10016 *) #ifdef wrap a few #defines in httpd.h to make life easier on
10017 some ports. [Ralf Engelschall]
10019 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
10021 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
10023 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
10025 Changes with Apache 1.2.5
10027 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
10028 only an issue on systems without a MAXDNAME define or where
10029 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
10031 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
10034 *) Fix core dump in the ftp proxy when reading incorrectly formatted
10035 directory listings. [Marc Slemko]
10037 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
10040 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
10041 is used to read various types of files such as htaccess and
10042 htpasswd files. [Marc Slemko]
10044 *) SECURITY: Ensure that the buffer returned by ht_time is always
10045 properly null terminated. [Marc Slemko]
10047 *) SECURITY: General mod_include cleanup, including fixing several
10048 possible buffer overflows and a possible infinite loop. This cleanup
10049 was done against 1.3 code and then backported to 1.2, the result
10050 is a large difference (due to indentation cleanup in 1.3 code).
10051 Users interested in seeing a smaller set of relevant differences
10052 should consider comparing against src/modules/standard/mod_include.c
10053 from the 1.3b3 release. Non-indentation changes to mod_include
10054 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
10056 *) SECURITY: Numerous changes to mod_imap in a general cleanup
10057 including fixing a possible buffer overflow. This cleanup also
10058 was done with 1.3 code as a basis, see the the previous note
10059 about mod_include. [Dean Gaudet]
10061 *) SECURITY: If a htaccess file can not be read due to bad
10062 permissions, deny access to the directory with a HTTP_FORBIDDEN.
10063 The previous behavior was to ignore the htaccess file if it could not
10064 be read. This change may make some setups with unreadable
10065 htaccess files stop working. PR#817 [Marc Slemko]
10067 *) SECURITY: no2slash() was O(n^2) in the length of the input.
10068 Make it O(n). This inefficiency could be used to mount a denial
10069 of service attack against the Apache server. Thanks to
10070 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
10071 this. [Dean Gaudet]
10073 *) mod_include used uninitialized data for some uses of && and ||.
10074 [Brian Slesinsky <bslesins@wired.com>] PR#1139
10076 *) mod_imap should decline all non-GET methods.
10077 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
10079 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10081 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10082 r->filename. Since those two are meant to be in sync with each other
10083 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
10085 *) mod_include did not properly handle all possible redirects from sub-
10086 requests. [Ken Coar]
10088 *) Inetd mode (which is buggy) uses timeouts without having setup the
10089 jmpbuffer. [Dean Gaudet] PR#1064
10091 *) Work around problem under Linux where a child will start looping
10092 reporting a select error over and over.
10093 [Rick Franchuk <rickf@transpect.net>] PR#1107
10095 Changes with Apache 1.2.4
10097 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
10098 always making requests with the full-URI instead of just the URI path.
10099 [Marc Slemko, Roy Fielding]
10101 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
10102 on this platform. [Marc Slemko]
10104 Changes with Apache 1.2.3
10106 *) The request to a remote proxy was mangled if it was generated as the
10107 result of a ProxyPass directive. URL schemes other than http:// were not
10108 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
10109 PR#812 [Lars Eilebrecht]
10111 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10112 information for case where proxy module is not available. [Marc Slemko]
10114 *) Force proxy to always respond as HTTP/1.0, which it was failing to
10115 do for errors and cached responses. [Roy Fielding]
10117 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
10119 Changes with Apache 1.2.2 [not released]
10121 *) Fixed another long-standing bug in sub_req_lookup_file where it would
10122 happily skip past access checks on subdirectories looked up with relative
10123 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
10126 *) Add lockfile name to error message printed out when
10127 USE_FLOCK_SERIALIZED_ACCEPT is defined.
10130 *) Enhanced the chunking and error handling inside the buffer functions.
10131 [Dean Gaudet, Roy Fielding]
10133 *) When merging the main server's <Directory> and <Location> sections into
10134 a vhost, put the main server's first and the vhost's second. Otherwise
10135 the vhost can't override the main server. [Dean Gaudet] PR#717
10137 *) The <Directory> code would merge and re-merge the same section after
10138 a match was found, possibly causing problems with some modules.
10141 *) Fixed an infinite loop in mod_imap for references above the server root.
10142 [Dean Gaudet] PR#748
10144 *) mod_include cleanup showed that handle_else was being used to handle
10145 endif. It didn't cause problems, but it was cleaned up too.
10148 *) Last official synchronization of mod_rewrite with author version (because
10149 mod_rewrite is now directly developed by the author at the Apache Group):
10150 o added diff between mod_rewrite 3.0.6+ and 3.0.9
10151 minus WIN32/NT stuff, but plus copyright removement.
10153 - workaround for detecting infinite rewriting loops
10154 - fixed setting of env vars when "-" is used as subst string
10155 - fixed forced response code on redirects (PR#777)
10156 - fixed cases where r->args is ""
10157 - kludge to disable locking on pipes under braindead SunOS
10158 - fix for rewritelog in cases where remote hostname is unknown
10159 - fixed totally damaged request_rec walk-back loop
10160 o remove static from local data and add static to global ones.
10161 o replaced ugly proxy finding stuff by simple
10162 find_linked_module("mod_proxy") call.
10163 o added missing negation char on rewritelog()
10164 o fixed a few comment typos

10195 *) API: In HTTP/1.1, whether or not a request message contains a body
10196 is independent of the request method and based solely on the presence
10197 of a Content-Length or Transfer-Encoding. Therefore, our default
10198 handlers need to be prepared to read a body even if they don't know
10199 what to do with it; otherwise, the body would be mistaken for the
10200 next request on a persistent connection. discard_request_body()
10201 has been added to take care of that. [Roy Fielding] PR#378
10203 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
10204 release version number, such that it always increases along the
10205 same lines as our source code branching. [Roy Fielding]
10207 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
10209 Changes with Apache 1.2.1
10211 *) SECURITY: Don't serve file system objects unless they are plain files,
10212 symlinks, or directories. This prevents local users from using pipes
10213 or named sockets to invoke programs for an extremely crude form of
10216 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
10217 could contain "../" allowing a local user to "publish" any file on
10218 the system. No slashes are allowed now. [Dean Gaudet]
10220 *) SECURITY: It was possible to violate the symlink Options using mod_dir
10221 (headers, readmes, titles), mod_negotiation (type maps), or
10222 mod_cern_meta (meta files). [Dean Gaudet]
10224 *) SECURITY: Apache will refuse to run as "User root" unless
10225 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
10227 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
10228 if it contained a .htaccess disallowing symlinks. This is contrary
10229 to the rule that symlink permissions are tested with the symlink
10230 options of the parent directory. [Dean Gaudet] PR#353
10232 *) CONFIG: The LockFile directive can be used to place the serializing
10233 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
10234 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
10237 *) Request processing now retains state of whether or not the request
10238 body has been read, so that internal redirects and subrequests will
10239 not try to read it twice (and block). [Roy Fielding]
10241 *) Add a placeholder in modules/Makefile to avoid errors with certain
10242 makes. [Marc Slemko]
10244 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
10245 [Dean Gaudet] PR#644
10247 *) mod_include was not properly changing the current directory.
10248 [Marc Slemko] PR#742
10250 *) Attempt to work around problems with third party libraries that do not
10251 handle high numbered descriptors (examples include bind, and
10252 solaris libc). On all systems apache attempts to keep all permanent
10253 descriptors above 15 (called the low slack line). Solaris users
10254 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
10255 which keeps all non-FILE * descriptors above 255. On all systems
10256 this should make supporting large numbers of vhosts with many open
10257 log files more feasible. If this causes trouble please report it,
10258 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
10259 [Dean Gaudet] various PRs
10261 *) Related to the last entry, network sockets are now opened before
10262 log files are opened. The only known case where this can cause
10263 problems is under Solaris with many virtualhosts and many Listen
10264 directives. But using -DHIGH_SLACK_LINE=256 described above will
10265 work around this problem. [Dean Gaudet]
10267 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
10270 *) Improved unix error response logging. [Marc Slemko]
10272 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
10273 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
10274 when a URL http://... was used in conjunction with a special
10275 redirect flag, e.g. R=permanent, the permanent status was lost.
10276 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>, Ralf S. Engelschall]

10310 Changes with Apache 1.2
10312 Changes with Apache 1.2b11
10314 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
10316 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
10317 [Doug MacEachern, Rob Hartill]
10319 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
10320 reading from one buffer and writing to another, at least until it has
10321 a custom timeout handler. [Roy Fielding and Petr Lampa]
10323 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
10324 apparently due to a mismatch between sigaction and setjmp.
10325 [Roy Fielding] PR#502
10327 *) Log correct status code if we timeout before receiving a request (408)
10328 or if we received a request-line that was too long to process (414).
10329 [Ed Korthof and Roy Fielding] PR#601
10331 *) Virtual hosts with the same ServerName, but on different ports, were
10332 not being selected properly. [Ed Korthof]
10334 *) Added code to return the requested IP address from proxy_host2addr()
10335 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
10336 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
10337 [Chuck Murcko] PR#614
10339 *) If multiple requests on a single connection are used to retrieve
10340 data from different virtual hosts, the virtual host list would be
10341 scanned starting with the most recently used VH instead of the first,
10342 causing most virtual hosts to be ignored.
10343 [Paul Sutton and Martin Mares] PR#610
10345 *) The OS/2 handling of process group was broken by a porting patch for
10346 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
10348 *) Inherit virtual server port from main server if none (or "*") is
10349 given for VirtualHost. [Dean Gaudet] PR#576
10351 *) If the lookup for a DirectoryIndex name with content negotiation
10352 has found matching variants, but none are acceptable, return the
10353 negotiation result if there are no more DirectoryIndex names to lookup.
10354 [Petr Lampa and Roy Fielding]
10356 *) If a soft_timeout occurs after keepalive is set, then the main child
10357 loop would try to read another request even though the connection
10358 has been aborted. [Roy Fielding]
10360 *) Configure changes: Allow for whitespace at the start of a
10361 Module declaration. Also, be more understanding about the
10362 CC=/OPTIM= format in Configuration. Finally, fix compiler
10363 flags if using HP-UX's cc compiler. [Jim Jagielski]
10365 *) Subrequests and internal redirects now inherit the_request from the
10366 original request-line. [Roy Fielding]
10368 *) Test for error conditions before creating output header fields, since
10369 we don't want the error message to include those fields. Likewise,
10370 reset the content_language(s) and content_encoding of the response
10371 before generating or redirecting to an error message, since the new
10372 message will have its own Content-* definitions. [Dean Gaudet]
10374 *) Restored the semantics of headers_out (headers sent only with 200..299
10375 and 304 responses) and err_headers_out (headers sent with all responses).
10376 Avoid the overhead of copying tables if err_headers_out is empty
10377 (the usual case). [Roy Fielding]
10379 *) Fixed a couple places where a check for the default Content-Type was
10380 not properly checking both the value configured by the DefaultType
10381 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
10382 of DEFAULT_TYPE to match the documented default (text/plain).
10383 [Dean Gaudet] PR#506
10385 *) Escape the HTML-sensitive characters in the Request-URI that is
10386 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
10388 *) Properly initialize the flock structures used by the mutex locking
10389 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
10392 *) The method for determining PATH_INFO has been restored to the pre-1.2b
10393 (and NCSA httpd) definition wherein it was the extra path info beyond
10394 the CGI script filename. The environment variable FILEPATH_INFO has
10395 been removed, and instead we supply the original REQUEST_URI to any
10396 script that wants to be Apache-specific and needs the real URI path.
10397 This solves a problem with existing scripts that use extra path info
10398 in the ScriptAlias directive to pass options to the CGI script.
10401 *) The _default_ change in 1.2b10 will change the behaviour on configs
10402 that use multiple Listen statements for listening on multiple ports.
10403 But that change is necessary to make _default_ consistent with other
10404 forms of <VirtualHost>. It requires such configs to be modified
10405 to use <VirtualHost _default_:*>. The documentation has been
10406 updated. [Dean Gaudet] PR#530
10408 *) If an ErrorDocument CGI script is used to respond to an error
10409 generated by another CGI script which has already read the message
10410 body of the request, the server would block trying to read the
10411 message body again. [Rob Hartill]
10413 *) signal() replacement conflicted with a define on QNX (and potentially
10414 other platforms). Fixed. [Ben Laurie] PR#512
10416 Changes with Apache 1.2b10
10418 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
10419 to be configured via -D in Configuration. [Dean Gaudet] PR#449
10421 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
10423 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
10425 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
10426 config, in case the hostent struct returned is trash.
10427 [Chuck Murcko] PR #491
10429 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
10430 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
10432 Changes with Apache 1.2b9 [never announced]
10434 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
10435 changes and in anticipation of 1.2 final release. [Roy Fielding]
10437 *) Fix problem with scripts not receiving a SIGPIPE when client drops
10438 the connection (e.g., when user presses Stop). Apache will now stop
10439 trying to send a message body immediately after an error from write.
10440 [Roy Fielding and Nathan Kurz] PR#335
10442 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
10443 than mod_alias, and mod_alias has higher priority than mod_proxy;
10444 rearranged other modules to enhance understanding of their purpose
10445 and relative order (and maybe even reduce some overhead).
10446 [Roy Fielding and Sameer Parekh]
10448 *) Fix graceful restart. Eliminate many signal-related race
10449 conditions in both forms of restart, and in SIGTERM. See
10450 htdocs/manual/stopping.html for details on stopping and
10451 restarting the parent. [Dean Gaudet]
10453 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
10454 memory allocator to avoid a behaviour that required extra blocks to
10455 be allocated. [Dean Gaudet]
10457 *) Allow suexec to access files relative to current directory but not
10458 above. (Excluding leading / or any .. directory.) [Ken Coar]

10462 PR#367, 368, 354, 453
10464 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
10465 while obtaining the /~user and save the username in a separate data
10466 area so that it won't be overwritten by the call to getgrgid(), and
10467 fix some misuse of the pool string allocation functions. Also fixes
10468 a general problem with parsing URL query info into args for CGI scripts.

10476 AuthDBAuthoritative. [Marc Slemko] PR#420
10478 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
10480 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
10481 object that can't be PUT, or FOOBAR for some method FOOBAR that
10482 apache doesn't know about at all). Log 404s that occur in mod_include.
10483 [Paul Sutton, John Van Essen]
10485 *) If a soft timeout (or lingerout) occurs while trying to flush a
10486 buffer or write inside buff.c or fread'ing from a CGI's output,
10487 then the timeout would be ignored. [Roy Fielding] PR#373
10489 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
10490 parsing of headers. If the terminating empty-line CRLF occurs starting
10491 at the 256th or 257th byte of output, then Navigator will think a normal
10492 image is invalid. We are guessing that this is because their initial
10493 read of a new request uses a 256 byte buffer. We check the bytes written
10494 so far and, if we are about to tickle the bug, we instead insert a
10495 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
10497 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
10498 of an external redirection. [Roy Fielding and Paul Sutton]
10500 *) Configure would create a broken Makefile if the configuration file
10501 contained a commented-out Rule. [Roy Fielding]
10503 *) Promote per_dir_config and subprocess_env from the subrequest to the
10504 main request in mod_negotiation. In particular this fixes a bug
10505 where <Files> sections wouldn't properly apply to negotiated content.
10508 *) Fix a potential deadlock in mod_cgi script_err handling.
10509 [Ralf S. Engelschall]
10511 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
10512 [Mitchell Blank Jr]
10514 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
10515 .htaccess files because the RewriteBase was not replaced correctly.
10516 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
10517 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
10519 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
10520 1.x the settings are those of pre-1.2b8. For 2.x we include
10521 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
10522 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
10523 [Dean Gaudet] PR#336, PR#340
10525 *) Redirect did not preserve ?query_strings when present in the client's
10526 request. [Dean Gaudet]
10528 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
10530 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
10532 *) Add UnixWare compile/install instructions. [Chuck Murcko]
10534 *) Add mod_example (illustration of API techniques). [Ken Coar]
10536 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
10538 *) Improve handling of directories when filenames have spaces in them.
10541 *) For hosts with multiple IP addresses, try all additional addresses if
10542 necessary to get a connect. Fail only if hostent address list is
10543 exhausted. [Chuck Murcko]
10545 *) More signed/unsigned port fixes. [Dean Gaudet]
10547 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
10550 Changes with Apache 1.2b8
10552 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
10553 to it. [Marc Slemko]
10555 *) The addition of <Location> and <File> directives made the
10556 sub_req_lookup_simple() function bogus, so we now handle
10557 the special cases directly. [Dean Gaudet]
10559 *) We now try to log where the server is dumping core when a fatal
10560 signal is received. [Ken Coar]
10562 *) Improved lingering_close by adding a special timeout, removing the
10563 spurious log messages, removing the nonblocking settings (they
10564 are not needed with the better timeout), and adding commentary
10565 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
10566 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
10568 *) Send error messages about setsockopt failures to the server error
10569 log instead of stderr. [Roy Fielding]
10571 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
10573 *) Stopgap solution for CGI 3-second delay with server-side includes: if
10574 processing a subrequest, allocate memory from r->main->pool instead
10575 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
10576 in the middle of an SSI request. [Dean Gaudet] PR #122
10578 *) Fixed status of response when POST is received for a nonexistent URL
10579 (was sending 405, now 404) and when any method is sent with a
10580 full-URI that doesn't match the server and the server is not acting
10581 as a proxy (was sending 501, now 403). [Roy Fielding]
10583 *) Host port changed to unsigned short. [Ken Coar] PR #276
10585 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
10587 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
10589 *) Report extra info from errno with many errors that cause httpd to exit.
10590 spawn_child, popenf, and pclosef now have valid errno returns in the
10591 event of an error. Correct problems where errno was stomped on
10592 before being reported. [Dean Gaudet]
10594 *) In the proxy, if the cache filesystem was full, garbage_coll() was
10595 never called, and thus the filesystem would remain full indefinitely.
10596 We now also remove incomplete cache files left if the origin server
10597 didn't send a Content-Length header and either the client has aborted
10598 transfer or bwrite() to client has failed. [Petr Lampa]
10600 *) Fixed the handling of module and script-added header fields.
10601 Improved the interface for sending header fields and reduced
10602 the duplication of code between sending okay responses and errors.
10603 We now always send both headers_out and err_headers_out, and
10604 ensure that the server-reserved fields are not being overridden,
10605 while not overriding those that are not reserved. [Roy Fielding]
10607 *) Moved transparent content negotiation fields to err_headers_out
10608 to reflect above changes. [Petr Lampa]
10610 *) Fixed the determination of whether or not we should make the
10611 connection persistent for all of the cases where some other part
10612 of the server has already indicated that we should not. Also
10613 improved the ordering of the test so that chunked encoding will
10614 be set whenever it is desired instead of only when KeepAlive
10615 is enabled. Added persistent connection capability for most error
10616 responses (those that do not indicate a bad input stream) when
10617 accessed by an HTTP/1.1 client. [Roy Fielding]
10619 *) Added missing timeouts for sending header fields, error responses,
10620 and the last chunk of chunked encoding, each of which could have
10621 resulted in a process being stuck in write forever. Using soft_timeout
10622 requires that the sender check for an aborted connection rather than
10623 continuing after an EINTR. Timeouts that used to be initiated before
10624 send_http_header (and never killed) are now initiated only within or
10625 around the routines that actually do the sending, and not allowed to
10626 propagate above the caller. [Roy Fielding]
10628 *) mod_auth_anon required an @ or a . in the email address, not both.
10631 *) per_dir_defaults weren't set correctly until directory_walk for
10632 name-based vhosts. This fixes an obscure bug with the wrong config
10633 info being used for vhosts that share the same ip as the server.
10636 *) Improved generation of modules/Makefile to be more generic for
10637 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
10639 *) Generate makefile dependency for Configuration based on the actual
10640 name given when running the Configure process. [Dean Gaudet]
10642 *) Fixed problem with vhost error log not being set prior to
10643 initializing virtual hosts. [Dean Gaudet]
10645 *) Fixed infinite loop when a trailing slash is included after a type map
10646 file URL (extra path info). [Petr Lampa]
10648 *) Fixed server status updating of per-connection counters. [Roy Fielding]
10650 *) Add documentation for DNS issues (reliability and security), and try
10651 to explain the virtual host matching process. [Dean Gaudet]
10653 *) Try to continue gracefully by disabling the vhost if a DNS lookup
10654 fails while parsing the configuration file. [Dean Gaudet]
10656 *) Improved calls to setsockopt. [Roy Fielding]
10658 *) Negotiation changes: Don't output empty content-type in variant list;
10659 Output charset in variant list; Return sooner from handle_multi() if
10660 no variants found; Add handling of '*' wildcard in Accept-Charset.
10661 [Petr Lampa and Paul Sutton]
10663 *) Fixed overlaying of request/sub-request notes and headers in
10664 mod_negotiation. [Dean Gaudet]
10666 *) If two variants' charset quality are equal and one is the default
10667 charset (iso-8859-1), then prefer the variant that was specifically
10668 listed in Accept-Charset instead of the default. [Petr Lampa]
10670 *) Memory allocation problem in push_array() -- it would corrupt memory
10671 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
10673 *) invoke_handler() doesn't handle mime arguments in content-type
10674 [Petr Lampa] PR#160
10676 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
10679 *) Fixed problem with ErrorDocument not working for virtual hosts
10680 due to one of the performance changes in 1.2b7. [Dean Gaudet]
10682 *) Log an error message if we get a request header that is too long,
10683 since it may indicate a buffer overflow attack. [Marc Slemko]
10685 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
10686 not reject URLs without a double-slash, as per RFC2068 section 3.2.
10687 [Ken Coar] PR #146, #187
10689 *) Added table entry placeholder for new header_parser callback
10690 in all of the distributed modules. [Ken Coar] PR #191
10692 *) Allow for cgi files without the .EXE extension on them under OS/2.
10693 [Garey Smiley] PR #59
10695 *) Fixed error message when resource is not found and URL contains
10696 path info. [Petr Lampa and Dean Gaudet] PR #40
10698 *) Fixed user and server confusion over what should be a virtual host
10699 and what is the main server, resulting in access to something
10700 other than the name defined in the virtualhost directive (but
10701 with the same IP address) failing. [Dean Gaudet]
10703 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
10704 AIX; improves the redirection stuff to enable the users to generally
10705 redirect to http, https, gopher and ftp; added TIME variable for
10706 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
10707 special patterns >STRING, <STRING and =STRING to RewriteCond, which
10708 can be used in conjunction with %{TIME} or other variables to create
10709 time-dependent rewriting rules. [Ralf S. Engelschall]
10711 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
10712 Module authors may need to adjust their code for proper cleanup to take
10713 place (that is, call note_cleanups_for_fd()). This change fixes problems
10714 with file descriptors being erroneously closed when the proxy module was
10715 in use. [Ben Laurie]
10717 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
10718 initgroups() to hose the group information needed for later
10719 comparisons. [Randy Terbush]
10721 *) Remove unnecessary call to va_end() in create_argv() which
10722 caused a SEGV on some systems.
10724 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
10727 *) Clear memory allocated for listeners. [Randy Terbush]
10729 *) Improved handling of IP address as a virtualhost address and
10730 introduced "_default_" as a synonym for the default vhost config.
10731 [Dean Gaudet] PR #212
10733 Changes with Apache 1.2b7
10735 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
10737 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
10739 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
10740 - replace protocol response numbers with symbols
10741 - save variant-list into main request notes
10742 - free allocated memory from subrequests
10743 - merge notes, headers_out and err_headers_out
10745 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
10746 "HTTP/#.# ###*" to be more lenient about what we accept.
10749 *) more proxy FTP bug fixes:
10750 - Changed send_dir() to remove user/passwd from displayed URL.
10751 - Changed login error messages to be more descriptive.
10752 - remove setting of SO_DEBUG socket option
10753 - Make ftp_getrc() more lenient about multiline responses,
10754 specifically, 230 responses which don't have continuation 230-
10755 on each line). These seem to be all NT FTP servers, and while
10756 perhaps questionable, they appear to be legal by RFC 959.
10757 - Add missing kill_timeout() after transfer to user completes.
10760 *) Fixed problem where a busy server could hang when restarting
10761 after being sent a SIGHUP due to child processes not exiting.
10764 *) Modify mod_include escaping so a '\' only signifies an escaped
10765 character if the next character is one that needs
10766 escaping. [Ben Laurie]
10768 *) Eliminated possible infinite loop in mod_imap when relative URLs are
10769 used with a 'base' directive that does not have a '/' in it.
10770 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
10772 *) Reduced the default timeout from 1200 seconds to 300, and the
10773 one in the sample configfile from 400 to 300. [Marc Slemko]
10775 *) Stop vbprintf from crashing if given a NULL string pointer;
10776 print (null) instead. [Ken Coar]
10778 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
10779 [Marc Slemko and Roy Fielding]
10781 *) Fixed problem with mod_cgi-generated internal redirects trying to
10782 read the request message-body twice. [Archie Cobbs and Roy Fielding]
10784 *) Reduced timeout on lingering close, removed possibility of a blocked
10785 read causing the child to hang, and stopped logging of errors if
10786 the socket is not connected (reset by client). [Roy Fielding]
10788 *) Rearranged main child loop to remove duplication of code in
10789 select/accept and keep-alive requests, fixed several bugs regarding
10790 checking scoreboard_image for exit indication and failure to
10791 account for all success conditions and trap all error conditions,
10792 prevented multiple flushes before closing the socket; close the entire
10793 socket buffer instead of just one descriptor, prevent logging of
10794 EPROTO and ECONNABORTED on platforms where supported, and generally
10795 improved readability. [Roy Fielding]
10797 *) Extensive performance improvements. Cleaned up inefficient use of
10798 auto initializers, multiple is_matchexp calls on a static string,
10799 and excessive merging of response_code_strings. [Dean Gaudet]
10801 *) Added double-buffering to mod_include to improve performance on
10802 server-side includes. [Marc Slemko]
10804 *) Several fixes for suexec wrapper. [Randy Terbush]
10805 - Make wrapper work for files on NFS filesystem.
10806 - Fix portability problem of MAXPATHLEN.
10807 - Fix array overrun problem in clean_env().
10808 - Fix allocation of PATH environment variable
10810 *) Removed extraneous blank line is description of mod_status chars.
10813 *) Logging of errors from the call_exec routine simply went nowhere,
10814 since the logfile fd has been closed, so now we send them to stderr.
10815 [Harald T. Alvestrand]
10817 *) Fixed core dump when DocumentRoot is a CGI.
10818 [Ben Laurie, reported by geddis@tesserae.com]
10820 *) Fixed potential file descriptor leak in mod_asis; updated it and
10821 http_core to use pfopen/pfclose instead of fopen/fclose.
10822 [Randy Terbush and Roy Fielding]
10824 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
10825 as the DEC Alpha which is 64-bit but uses 32-bit ints.
10826 [Dean Gaudet and Ken Coar]
10828 *) Return a 302 response code to the client when sending a redirect
10829 due to a missing trailing '/' on a directory instead of a 301; now
10830 it is cacheable. [Markus Gyger]
10832 *) Fix condition where, if a bad directive occurs in .htaccess, and
10833 sub_request() goes first to this directory, then log_reason() will
10834 SIGSEGV because it doesn't have initialized r->per_dir_config.
10835 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
10837 *) Fix handling of lang_index in is_variant_better(). This was
10838 causing problems which resulted in the server sending the
10839 wrong language document in some cases. [Petr Lampa]
10841 *) Remove free() from clean_env() in suexec wrapper. This was nuking
10842 the clean environment on some systems.
10844 *) Tweak byteserving code (e.g. serving PDF files) to work around
10845 bugs in Netscape Navigator and Microsoft Internet Explorer.
10846 Emit Content-Length header when sending multipart/byteranges.
10849 *) Port to HI-UX/WE2. [Nick Maclaren]
10851 *) Port to HP MPE operating system for HP 3000 machines
10852 [Mark Bixby <markb@cccd.edu>]
10854 *) Fixed bug which caused a segmentation fault if only one argument
10855 given to RLimit* directives. [Ed Korthof]
10857 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
10859 *) Improved buffered output to the client by delaying the flush decision
10860 until the BUFF code is actually about to read the next request.
10861 This fixes a problem introduced in 1.2b5 with clients that send
10862 an extra CRLF after a POST request. Also improved chunked output
10863 performance by combining writes using writev() and removing as
10864 many bflush() calls as possible. NOTE: Platforms without writev()
10865 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
10866 or Configure, unless we have already done so. [Dean Gaudet]
10868 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
10870 *) Fixed mod_info output corruption bug introduced by buffer overflow
10871 fixes. [Dean Gaudet]
10873 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
10874 for the special case of a 304 response. [Paul Sutton]
10876 *) Improved handling of TRACE method by bypassing normal method handling
10877 and header parsing routines; fixed Allow response to always allow TRACE.
10880 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
10882 *) Cleaned-up some of the generated HTML. [Ken Coar]
10884 Changes with Apache 1.2b6
10886 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
10888 *) Fix typo introduced in fix for potential infinite loop around
10889 accept() in child_main(). This change caused the rev to 1.2b6.
10890 1.2b5 was never a public beta.
10892 Changes with Apache 1.2b5
10894 *) Change KeepAlive semantics (On|Off instead of a number), add
10895 MaxKeepAliveRequests directive. [Alexei Kosut]
10897 *) Various NeXT compilation patches, as well as a change in
10898 regex/regcomp.c since that file also used a NEXT define.
10901 *) Allow * to terminate the end of a directory match in mod_dir.
10902 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
10904 *) Don't call can_exec() if suexec_enabled. Calling this requires
10905 scripts executed by the suexec wrapper to be world executable, which
10906 defeats one of the advantages of running the wrapper. [Randy Terbush]
10908 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
10911 *) Migration from sprintf() to snprintf() to avoid buffer
10912 overflows. [Marc Slemko]
10914 *) Provide portable snprintf() implementation (ap_snprintf)
10915 as well as *cvt family. [Jim Jagielski]
10917 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
10920 *) Remove mod_fastcgi.c from the distribution. This module appears
10921 to be maintained more through the Open Market channels and should
10922 continue to be easily available at http://www.fastcgi.com/
10924 *) Fixed bug in modules/Makefile that wouldn't allow building in more
10925 than one subdirectory (or cleaning, either). [Jeremy Laidman]
10927 *) mod_info assumed that the config files were relative to ServerRoot.
10930 *) CGI scripts called as an error document resulting from failed
10931 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
10933 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
10936 *) Properly check errno to prevent display of a directory index
10937 when server receives a long enough URL to confuse stat().
10940 *) Several security enhancements to suexec wrapper. It is _highly_
10941 recommended that previously installed versions of the wrapper
10942 be replaced with this version. [Randy Terbush, Jason Dour]
10944 - ~user execution now properly restricted to ~user's home
10945 directory and below.
10946 - execution restricted to UID/GID > 100
10947 - restrict passed environment to known variables
10948 - call setgid() before initgroups() (portability fix)
10949 - remove use of setenv() (portability fix)
10951 *) Add HTTP/1.0 response forcing. [Ben Laurie]
10953 *) Add access control via environment variables. [Ben Laurie]
10955 *) Add rflush() function. [Alexei Kosut]
10957 *) remove duplicate pcalloc() call in new_connection().
10959 *) Fix incorrect comparison which could allow number of children =
10960 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
10961 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
10963 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
10964 AIX PS/2, CONVEXOS. [Jim Jagielski]
10966 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
10967 It's more portable. [Martin Kraemer]
10969 *) Replace references to make in Makefile.tmpl with $(MAKE).
10972 *) Add ProxyBlock directive w/IP address caching. Add IP address
10973 caching to NoCache directive as well. ProxyBlock works with all
10974 handlers; NoCache now also works with FTP for anonymous logins.
10975 Still more code cleanup. [Chuck Murcko]
10977 *) Add "header parse" API hook [Ben Laurie]
10979 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
10981 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
10983 *) Correctly allow access and auth directives in <Files> sections in
10984 server config files. [Alexei Kosut]
10986 *) Fix bug with ServerPath that could cause certain files to be not
10987 found by the server. [Alexei Kosut]
10989 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
10990 double-quote from text and so that it properly checks for unsupported
10991 status codes using the new index_of_response interface. [Roy Fielding]
10993 *) Multiple fixes to the lingering_close code in order to avoid being
10994 interrupted by a stray timeout, to avoid lingering on a connection
10995 that has already been aborted or never really existed, to ensure that
10996 we stop lingering as soon as any error condition is received, and to
10997 prevent being stuck indefinitely if the read blocks. Also improves
10998 reporting of error conditions. [Marc Slemko and Roy Fielding]
11000 *) Fixed initialization of parameter structure for sigaction.
11001 [mgyger@itr.ch, Adrian Filipi-Martin]
11003 *) Fixed reinitializing the parameters before each call to accept and
11004 select, and removed potential for infinite loop in accept.
11005 [Roy Fielding, after useful PR from adrian@virginia.edu]
11007 *) Fixed condition where, if a child fails to fork, the scoreboard would
11008 continue to say SERVER_STARTING forever. Eventually, the main process
11009 would refuse to start new children because count_idle_servers() will
11010 count those SERVER_STARTING entries and will always report that there
11011 are enough idle servers. [Phillip Vandry]
11013 *) Fixed bug in bcwrite regarding failure to account for partial writes.
11014 Avoided calling bflush() when the client is pipelining requests.
11015 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
11017 *) Added description of "." mode in server-status [Jim Jagielski]
11019 Changes with Apache 1.2b4
11021 *) Fix possible race condition in accept_mutex_init() that
11022 could leave a small security hole open allowing files to be
11023 overwritten in cases where the server UID has write permissions.
11026 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
11028 *) Fix portablity problem in util_script where ARG_MAX may not be
11029 defined for some systems.
11031 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
11034 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
11035 style magic #! token for better script portability. [Garey Smiley]
11037 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
11038 execution for ~userdir CGI. [Jason Dour]
11040 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
11042 *) Fix month off by one in suexec wrapper logging.
11044 Changes with Apache 1.2b3:
11046 *) Fix error in mod_cgi which could cause resources not to be properly
11047 freed, or worse. [Dean Gaudet]
11049 *) Fix find_string() NULL pointer dereference. [Howard Fear]
11051 *) Add set_flag_slot() at the request of Dirk and others.
11054 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
11056 *) Add changes to improve the error message given for invalid
11057 ServerName parameters. [Dirk vanGulik]
11059 *) Add "Authoritative" directive for Auth modules that don't
11060 currently have it. This gives admin control to assign authoritative
11061 control to an authentication scheme and allow "fall through" for
11062 those authentication modules that aren't "Authoritative" thereby
11063 allowing multiple authentication mechanisms to be chained.
11066 *) Remove requirement for ResourceConfig/AccessConfig if not using
11067 the three config file layout. [Randy Terbush]
11069 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
11071 *) Changes to suexec wrapper to fix the following problems:
11072 1. symlinked homedirs will kill ~userdirs.
11073 2. initgroups() on Linux 2.0.x clobbers gr->grid.
11074 3. CGI command lines paramters problems
11075 4. pw-pwdir for "docroot check" still the httpd user's pw record.
11076 [Randy Terbush, Jason Dour]
11078 *) Change create_argv() to accept variable arguments. This fixes
11079 a problem where arguments were not getting passed to the CGI via
11080 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
11082 *) Collapse multiple slashes in path URLs to properly apply
11083 handlers defined by <Location>. [Alexei Kosut]
11085 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
11087 *) Improve the accuracy of request duration timings by setting
11088 r->request_time in read_request_line() instead of read_request().
11091 *) Reset timeout while reading via get_client_block() in mod_cgi.c
11092 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
11094 *) Add the ability to pass different Makefile.tmpl files to Configure
11095 using the -make flag. [Rob Hartill]
11097 *) Fix coredump triggered when sending a SIGHUP to the server caused
11098 by an assertion failure, in turn caused by an uninitialised field in a
11102 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
11103 PATH_INFO from previous versions of Apache (in certain situations,
11104 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
11105 [later removed in 1.2b11]
11107 *) Add rwrite() function to API to allow for sending strings of
11108 arbitrary length. [Doug MacEachern]
11110 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
11112 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
11113 NeXT. [Jim Jagielski]
11115 *) Removed recent modification to promote the status code on internal
11116 redirects, since the correct fix was to change the default log format
11117 in mod_log_config so that it outputs the original status. [Rob Hartill]
11119 Changes with Apache 1.2b2:
11121 *) Update set_signals() to use sigaction() for setting handlers.
11122 This appears to fix a re-entrant problem in the seg_fault()
11123 bus_error() handlers. [Randy Terbush]
11125 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
11127 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
11129 *) proxy_http.c bugfixes: [Chuck Murcko]
11130 1) fixes possible NULL pointer reference w/NoCache
11131 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
11132 host would cache nothing if it was in the local domain,
11133 and the local domain was in the NoCache list)
11134 3) Adds Host: header when not available
11135 4) Some code cleanup and clarification
11137 *) mod_include.c bugfixes:
11138 1) Fixed an ommission that caused include variables to not
11139 be parsed in config errmsg directives [Howard Fear]
11140 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
11141 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
11142 4) Allow backslash-escaping to all quoted text
11143 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
11144 5) Pass variable to command line if not set in XSSI's env
11147 *) Fix infinite loop when processing Content-language lines in
11148 type-map files. [Alexei Kosut]
11150 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
11152 *) Fixed problem in set_[user|group] that prevented CGI execution
11153 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
11155 *) Added PORTING information file. [Jim Jagielski]
11157 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
11159 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
11161 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
11162 USE_FCNTL_SERIALIZED_ACCEPT was intended.
11164 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
11165 which caused problems of systems where socket s_addr is >32bits.
11167 *) Added comment to explain (r->chunked = 1) side-effect in
11168 http_protocol.c [Roy Fielding]
11170 *) Replaced use of index() in mod_expires.c with more appropriate
11171 and portable isdigit() test. [Ben Laurie]
11173 *) Updated Configure for ...
11174 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
11175 *-dg-dgux* (bad pattern match)
11176 QNX (DEF_WANTHSREGEX=yes)
11177 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
11179 *-unixware211 (new)
11180 and added some user diagnostic info. [Ben Laurie]
11182 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
11183 for better portability. [Jim Jagielski]
11185 *) Updated helpers/GuessOS for ...
11186 SCO 5 (recognize minor releases)
11187 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
11188 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
11189 IRIX64 (-sgi-irix64)
11190 ULTRIX (-unknown-ultrix)
11191 SINIX (-whatever-sysv4)
11192 NCR Unix (-ncr-sysv4)
11193 and fixed something in helpers/PrintPath [Ben Laurie]
11195 Changes with Apache 1.2b1
11197 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
11199 Changes with Apache 1.1.1
11201 *) Fixed bug where Cookie module would make two entries in the
11202 logfile for each access [Mark Cox]
11204 *) Fixed bug where Redirect in .htaccess files would cause memory
11205 leak. [Nathan Neulinger]
11207 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
11209 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
11211 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
11213 Changes with Apache 1.1.0
11215 *) Bring NeXT support up to date. [Takaaki Matsumoto]
11217 *) Bring QNX support up to date. [Ben Laurie]
11219 *) Make virtual hosts default to main server keepalive parameters.
11220 [Alexei Kosut, Ben Laurie]
11222 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
11224 *) Fix missing address family for connect, also remove unreachable statement
11225 in mod_proxy. [Ben Laurie]
11227 *) mod_env now turned on by default in Configuration.tmpl.
11229 *) Bugs which were fixed:
11230 a) yet more mod_proxy bugs [Ben Laurie]
11231 b) CGI works again with inetd [Alexei Kosut]
11232 c) Leading colons were stripped from passwords [osm@interguide.com]
11233 d) Another fix to multi-method Limit problem [jk@tools.de]
11235 Changes with Apache 1.1b4
11237 *) r->bytes_sent variable restored. [Robert Thau]
11239 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
11241 *) More possibly unsecure programs removed from the support directory.
11243 *) More mod_auth_msql authentication improvements.
11245 *) VirtualHosts based on Host: headers no longer conflict with the
11248 *) OS/2 compatibility enhancements. [Gary Smiley]
11250 *) POST now allowed to directory index CGI scripts.
11252 *) Actions now work with files of the default type.
11254 *) Bugs which were fixed:
11255 a) more mod_proxy bugs
11256 b) early termination of inetd requests
11257 c) compile warnings on several systems
11258 d) problems when scripts stop reading output early
11260 Changes with Apache 1.1b3
11262 *) Much of cgi-bin and all of cgi-src has been removed, due to
11263 various security holes found and that we could no longer support
11266 *) The "Set-Cookie" header is now special-cased to not merge multiple
11267 instances, since certain popular browsers can not handle multiple
11268 Set-Cookie instructions in a single header. [Paul Sutton]
11270 *) rprintf() added to buffer code, occurrences of sprintf removed.
11273 *) CONNECT method for proxy module, which means tunneling SSL should work.
11274 (No crypto needed) Also a NoCache config directive.
11276 *) Several API additions: pstrndup(), table_unset() and get_token()
11277 functions now available to modules.
11279 *) mod_imap fixups, in particular Location: headers are now complete
11282 *) New "info" module which reports on installed module set through a
11283 special URL, a la mod_status.
11285 *) "ServerPath" directive added - allows for graceful transition
11286 for Host:-header-based virtual hosts.
11288 *) Anonymous authentication module improvements.
11290 *) MSQL authentication module improvements.
11292 *) Status module design improved - output now table-based. [Ben Laurie]
11294 *) htdigest utility included for use with digest authentication
11297 *) mod_negotiation: Accept values with wildcards to be treated with
11298 less priority than those without wildcards at the same quality
11299 value. [Alexei Kosut]
11301 *) Bugs which were fixed:
11302 a) numerous mod_proxy bugs
11303 b) CGI early-termination bug [Ben Laurie]
11304 c) Keepalives not working with virtual hosts
11305 d) RefererIgnore problems
11306 e) closing fd's twice in mod_include (causing core dumps on
11307 Linux and elsewhere).
11309 Changes with Apache 1.1b2
11312 a) core dumps in mod_digest
11313 b) truncated hostnames/ip address in the logs
11314 c) relative URL's in mod_imap map files
11316 Changes with Apache 1.1b1
11318 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
11320 Changes with Apache 1.0.3
11322 *) Internal redirects which occur in mod_dir.c now preserve the
11323 query portion of a request (the bit after the question mark).
11326 *) Escape active characters '<', '>' and '&' in html output in
11327 directory listings, error messages and redirection links.
11330 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
11332 *) Fix for POSIX compliance in waiting for processes in alloc.c.
11335 *) setsockopt no longer takes a const declared argument [Martijn Koster]
11337 *) Reset timeout timer after each successful fwrite() to the network.
11338 This patch adds a reset_timeout() procedure that is called by
11339 send_fd() to reset the timeout ever time data is written to the net.
11342 *) timeout() signal handler now checks for SIGPIPE and reports
11343 lost connections in a more user friendly way. [Rob Hartill]
11345 *) Location of the "scoreboard" file which used to live in /tmp is
11346 now configurable (for OSes that can't use mmap) via ScoreBoardFile
11347 which works similar to PidFile (in httpd.conf) [Rob Hartill]
11349 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
11351 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
11352 which caused a SEGV with cookies enabled
11354 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
11357 *) Log the UNIX textual error returned by some system calls, in
11358 particular errors from accept() [David Robinson]
11360 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
11362 Changes with Apache 1.0.2
11364 *) patch to get Apache compiled on UnixWare 2.x, recommended as
11365 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
11367 *) Fix get_basic_auth_pw() to set the auth_type of the request.
11370 *) past changes to http_config.c to only use the
11371 setrlimit function on systems defining RLIMIT_NOFILE
11372 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
11373 for SUNOS and prototypes the needed functions.
11375 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
11378 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
11380 *) Merge multiple headers from CGI scripts instead of taking last
11381 one. [David Robinson]
11383 *) Add support for SCO 5. [Ben Laurie]
11385 Changes with Apache 1.0.1
11387 *) Silence mod_log_referer and mod_log_agent if not configured
11390 *) Recursive includes can occur if the client supplies PATH_INFO data
11391 and the server provider uses relative links; as file.html
11392 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
11394 *) The replacement for initgroups() did not call {set,end}grent(). This
11395 had two implications: if anything else used getgrent(), then
11396 initgroups() would fail, and it was consuming a file descriptor.
11399 *) On heavily loaded servers it was possible for the scoreboard to get
11400 out of sync with reality, as a result of a race condition.
11401 The observed symptoms are far more Apaches running than should
11402 be, and heavy system loads, generally followed by catastrophic
11403 system failure. [Ben Laurie]
11405 *) Fix typo in license. [David Robinson]
11407 Changes with Apache 1.0.0 23 Nov 1995
11409 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
11411 Changes with Apache 0.8.16 05 Nov 1995
11413 *) New man page for 'httpd' added to support directory [David Robinson]
11415 *) .htgroup files can have more than one line giving members for a
11416 given group (each must have the group name in front), for NCSA
11417 back-compatibility [Robert Thau]
11419 *) Mutual exclusion around accept() is on by default for SVR4 systems
11420 generally, since they generally can't handle multiple processes in
11421 accept() on the same socket. This should cure flaky behavior on
11422 a lot of those systems. [David Robinson]
11424 *) AddType, AddEncoding, and AddLanguage directives take multiple
11425 extensions on a single command line [David Robinson]
11427 *) UserDir can be disabled for a given virtual host by saying
11428 "UserDir disabled" in the <VirtualHost> section --- it was a bug
11429 that this didn't work. [David Robinson]
11431 *) Compiles on QNX [Ben Laurie]
11433 *) Corrected parsing of ctime time format [David Robinson]
11435 *) httpd does a perror() before exiting if it can't log its pid
11436 to the PidFile, to make diagnosing the error a bit easier.
11439 *) <!--#include file="..."--> can no longer include files in the
11440 parent directory, for NCSA back-compatibility. [David Robinson]
11442 *) '~' is *not* escaped in URIs generated for directory listings
11445 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
11447 *) Fixed bug involving handling URIs with escaped %-characters
11448 in redirects [David Robinson]
11450 Changes with Apache 0.8.15 14 Oct 1995
11452 *) Switched to new, simpler license
11454 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
11456 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
11458 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
11460 *) Correctly handles internal redirects to files with names containing '%'
11463 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
11465 *) Use geteuid() rather than getuid() to see if we have root privilege,
11466 so that server correctly resets privilege if run setuid root. [Andrew
11469 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
11472 *) Fix relative URLs in imagemap files [Randy Terbush]
11474 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
11477 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
11478 entries all name the same one. [David Robinson]
11480 *) Fix directory listings with filenames containing unusual characters
11483 *) Better URI-escaping for generated URIs in directories with filenames
11484 containing unusual characters [Ben Laurie]
11486 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
11488 *) Unblock alarms on error return from spawn_child() [David Robinson]
11490 *) Sample Config files have extra note for SCO users [Ben Laurie]
11492 *) Configuration has note for HP-UX users [Rob Hartill]
11494 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
11496 *) Nuked bogus #define in httpd.h [David Robinson]
11498 *) Better test for whether a system has setrlimit() [David Robinson]
11500 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
11502 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
11505 Changes with Apache 0.8.14 19 Sep 1995
11507 *) Compiles on SCO ODT 3.0 [Ben Laurie]
11509 *) AddDescription works (better) [Ben Laurie]
11511 *) Leaves an intelligible error diagnostic when it can't set group
11512 privileges on standalone startup [Andrew Wilson]
11514 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
11515 that machine, which claims to be BSD but does not support RLIMIT.
11518 *) gcc -Wall no longer complains about an unused variable when util.c
11519 is compiled with -DMINIMAL_DNS [Andrew Wilson]
11521 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
11523 Changes with Apache 0.8.13 07 Sep 1995
11525 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
11527 *) Have built-in imagemap code recognize & honor Point directive [James
11530 *) Generate cleaner directory listings in directories with a mix of
11531 long and short filenames [Rob Hartill]
11533 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
11535 *) Properly default ServerName for virtual servers [Robert Thau]
11537 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
11538 Paul Richards and a cast of thousands...]
11540 *) On self-identified BSD systems (we don't try to guess any more),
11541 allocate a few extra file descriptors per virtual host with setrlimit,
11542 if we can, to avoid running out. [Randy Terbush]
11544 *) Write 22-character lock file name into buffer with enough space
11545 on startup [Konstantin Olchanski]
11547 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
11550 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
11552 *) Suppress -Wall warning by initializing variable in negotiation code
11553 [Tobias Weingartner]
11555 Changes with Apache 0.8.12 31 Aug 1995
11557 *) Doesn't pause three seconds after including a CGI script which is
11558 too slow to die off (this is done by not even trying to kill off
11559 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
11560 after the entire document has been processed). [Robert Thau]
11562 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
11564 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
11566 *) Allows .htaccess files to override <Directory> sections naming the
11567 same directory [David Robinson]
11569 *) Removed an efficiency hack in sub_req_lookup_uri which was
11570 causing certain extremely marginal cases (e.g., ScriptAlias of a
11571 *particular* index.html file) to fail. [David Robinson]
11573 *) Doesn't log an error when the requested URI requires
11574 authentication, but no auth header line was supplied by the
11575 client; this is a normal condition (the client doesn't no auth is
11576 needed here yet). [Robert Thau]
11578 *) Behaves more sanely when the name server loses its mind [Sean Welch]
11580 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
11582 *) RFC931 code no longer passes out name of prior clients on current
11583 requests if the current request came from a server that doesn't
11584 do RFC931. [David Robinson]
11586 *) Configuration script accepts "Module" lines with trailing whitespace.
11589 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
11591 *) Cleaned up comments in mod_cgi.c [Robert Thau]
11593 Changes with Apache 0.8.11 24 Aug 1995
11595 *) Wildcard <Directory> specifications work. [Robert Thau]
11597 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
11599 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
11600 the file being requested itself, in addition to the directories leading
11601 up to it. [Robert Thau]
11603 *) Logs access failures due to symlink checks or invalid client address
11604 in the error log [Roy Fielding, Robert Thau]
11606 *) Symlink checks deal correctly with systems where lstat of
11607 "/path/to/some/link/" follows the link. [Thau, Fielding]
11609 *) Doesn't reset DirectoryIndex to 'index.html' when
11610 other directory options are set in a .htaccess file. [Robert Thau]
11612 *) Clarified init code and nuked bogus warning in mod_access.c
11613 [Florent Guillaume]
11615 *) Corrected several directives in sample srm.conf
11616 --- includes corrections to directory indexing icon-related directives
11617 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
11618 icons for encodings right, and turning on AddEncoding by default).
11621 *) Corrected descriptions of args to AddIcon and AddAlt in command table
11624 *) INSTALL & README mention "contributed modules" directory [Brian
11627 *) Fixed English in the license language... "for for" --> "for".
11630 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
11631 mod_alias.c, merging it almost completely with handling of Alias, and
11632 adding a 'notes' field to the request_rec which allows the CGI module
11633 to discover whether the Alias module has put this request through
11634 ScriptAlias (which it needs to know for back-compatibility, as the old
11635 NCSA code did not check Options ExecCGI in ScriptAlias directories).
11638 Changes with Apache 0.8.10 18 Aug 1995
11640 *) AllowOverride applies to the named directory, and not just
11641 subdirectories. [David Robinson]
11643 *) Do locking for accept() exclusion (on systems that need it)
11644 using a special file created for the purpose in /usr/tmp, and
11645 not the error log; using the error log causes real problems
11646 if it's NFS-mounted; this is known to be the cause of a whole
11647 lot of "server hang" problems with Solaris. [David Robinson;
11648 thanks to Merten Schumann for help diagnosing the problem].
11650 Changes with Apache 0.8.9 12 Aug 1995
11652 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
11654 *) Nested includes see environment variables of the including document,
11655 for NCSA bug-compatibility (some sites have standard footer includes
11656 which try to print out the last-modified date). [Eric Hagberg/Robert
11659 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
11660 URI as a CGI script, even if it would have been treated as something
11661 else if requested directly, for NCSA back-compatibility. (Note that
11662 this means that people who know the name of the script can see the
11663 code just by asking for it). [Robert Thau]
11665 *) New version of dbmmanage script included in support directory as
11668 *) Check if scoreboard file couldn't be opened, and say so, rather
11669 then going insane [David Robinson]
11671 *) POST to CGI works on A/UX [Jim Jagielski]
11673 *) AddIcon and AddAlt commands work properly [Rob Hartill]
11675 *) NCSA server push works properly --- the Arena bug compatibility
11676 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
11677 if you still want the workaround). [Rob Hartill]
11679 *) If client didn't submit any Accept-encodings, ignore encodings in
11680 content negotiation. (NB this will all have to be reworked anyway
11681 for the new HTTP draft). [Florent Guillaume]
11683 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
11685 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
11687 *) Give Redirect priority over Alias, for NCSA bug compatibility
11690 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
11691 paralleling earlier bug fix for CGI [David Robinson]
11693 *) If DBM auth is improperly configured, report a server error and don't
11696 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
11697 it seems to work well enough without it (even in a 10 hits/sec
11698 workout), and the overhead for the locking under A/UX is
11699 alarmingly high (though it is very low on other systems).
11700 [Eric Hagberg, Jim Jagielski]
11702 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
11704 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
11705 Behlendorf/Eric Hagberg]
11707 *) More improvements to default Configuration for A/UX [Jim Jagielski]
11709 *) Compiles clean on NEXT [Rob Hartill]
11711 *) Compiles clean on SGI [Robert Thau]
11713 Changes with Apache 0.8.8 08 Aug 1995
11715 *) SunOS library prototypes now never included unless explicitly
11716 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
11717 people using GNU libc on SunOS are screwed by prototypes for the
11720 (Those who wish to compile clean with gcc -Wall on a standard
11721 SunOS setup need the prototypes, and may obtain them using
11722 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
11723 with nonstandard libraries are presumably competent to make their
11726 *) Strips trailing '/' characters off both args to the Alias command,
11727 to make 'Alias /foo/ /bar/' work.
11729 Changes with Apache 0.8.7 03 Aug 1995
11731 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
11732 [reported by David Robinson]
11734 *) Compiles clean on OSF/1 [David Robinson]
11736 *) Added some of the more recent significant changes (AddLanguage stuff,
11737 experimental LogFormat support) to CHANGES file in distribution root
11740 Changes with Apache 0.8.6 02 Aug 1995
11742 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
11743 (If you actually wanted a conditional GET which bypassed the cache, you
11744 couldn't get it). [Reported by Roy Fielding]
11746 *) Properly terminate headers on '304 Not Modified' replies to conditional
11747 GETs --- no browser we can find cares much, but the CERN proxy chokes.
11748 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
11750 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
11752 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
11753 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
11754 and older versions don't set the __SUNPRO_C preprocessor variable). On
11755 all other systems, these are never used anyway. [Reported by Mark Cox].
11757 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
11759 Changes with Apache 0.8.5 01 Aug 1995
11761 *) Added last-minute configurable log experiment, as optional module
11763 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
11764 properly. (One-line fix to http_protocol.c).
11766 *) Work around bogus behavior when reloading from Netscape.
11767 It's Netscape's bug --- for some reason they expect a request with
11768 If-modified-since: to not function as a conditional GET if it also
11769 comes with Pragma: no-cache, which is way out of line with the HTTP
11770 spec (according to Roy Fielding, the redactor).
11772 *) Added parameter to set maximum number of server processes.
11774 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
11777 *) IdentityCheck bugfix [Chuck Murcko].
11779 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
11781 *) More sample config file corrections; add extension to AddType for
11782 *.asis, move AddType generic description to its proper place, and
11783 fix miscellaneous typos. [ Alexei Kosut ]
11785 *) Deleted the *other* reference to the regents from the Berkeley
11786 legal disclaimer (everyplace).
11788 *) Nuked Shambhala name from src/README; had already cleaned it out
11789 of everywhere else.
11791 Changes with Apache 0.8.4
11793 *) Changes to server-pool management parms --- renamed current
11794 StartServers to MinSpareServers, created separate StartServers
11795 parameter which means what it says, and renamed MaxServers to
11796 MaxSpareServers (though the old name still works, for NCSA 1.4
11797 back-compatibility). The old names were generally regarded as
11798 too confusing. Also altered "docs" in sample config files.
11800 *) More improvements to default config files ---
11801 sample directives (commented out) for XBitHack, BindAddress,
11802 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
11803 defaults, AddTypes for send-as-is and imagemap magic types, and
11804 improvements to samples for DirectoryIndex [Alexei Kosut]
11806 *) Yet more improvements to default config files --- changes to
11807 Alexei's sample AddLanguage directives, and sample LanguagePriority
11808 [ Florent Guillaume ]
11810 *) Set config file locations properly if not set in httpd.conf
11813 *) Don't escape URIs in internal redirects multiple times; don't
11814 do that when translating PATH_INFO to PATH_TRANSLATED either.
11817 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
11819 Changes with Apache 0.8.3
11821 *) Edited distribution README to *briefly* summarize installation
11822 procedures, and give a pointer to the INSTALL file in the src/
11825 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
11826 recent NCSA distributions.
11828 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
11829 exist for the same directory, use both and don't segfault. [Reported
11832 *) Proper makefile dependencies [David Robinson]
11834 *) Note (re)starts in error log --- reported by Rob Hartill.
11836 *) Only call no2slash() after get_path_info() has been done, to
11837 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
11838 reported by Andrew Wilson, though this one is probably a real bug]
11840 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
11841 dump core when Referer is not supplied. [Randy Terbush]
11843 *) Lightly edited sample config files to refer people to our documentation
11844 instead of NCSA's, and to list Rob McCool as *original* author (also
11845 deleted his old, and no doubt non-functional email address). Would be
11846 nice to have examples of new features...
11848 Changes with Apache 0.8.2 19 Jul 1995
11850 *) Added AddLanuage code [Florent Guillaume]
11852 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
11854 *) All sorts of problems when MultiViews finds a directory. It would
11855 be nice if mod_dir.c was robust enough to handle that, but for now,
11856 just punt. [reported by Brian Behlendorf]
11858 *) Wait for all children on restart, to make sure that the old socket
11859 is gone and we can reopen it. [reported by Randy Terbush]
11861 *) Imagemap module is enabled in default Configuration
11863 *) RefererLog and UserAgentLog modules properly default the logfile
11866 *) Mark Cox's mod_cookies added to the distribution as an optional
11867 module (commented out in the default Configuration, and noted as
11868 an experiment, along with mod_dld). [Mark Cox]
11870 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
11872 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
11874 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
11876 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
11879 Changes with Apache 0.8.1
11881 *) New imagemap module [Randy Terbush]
11883 *) Replacement referer log module with NCSA-compatible RefererIgnore
11884 [Matthew Gray again]
11886 *) Don't mung directory listings with very long filenames.
11887 [Florent Guillaume]
11889 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
11891 *) New config script. See INSTALL for info. [Robert Thau]
11893 *) Scoreboard mechanism for regulating the number of extant server
11894 processes. MaxServers and StartServers defaults are the same as
11895 for NCSA, but the meanings are slightly different. (Actually,
11896 I should probably lower the MaxServers default to 10).
11898 Before asking for a new connection, each server process checks
11899 the number of other servers which are also waiting for a
11900 connection. If there are more than MaxServers, it quietly dies
11901 off. Conversely, every second, the root, or caretaker, process
11902 looks to see how many servers are waiting for a new connection;
11903 if there are fewer than StartServers, it starts a new one. This
11904 does not depend on the number of server processes already extant.
11905 The accounting is arranged through a "scoreboard" file, named
11906 /tmp/htstatus.*, on which each process has an independent file
11907 descriptor (they need to seek without interference).
11909 The end effect is that MaxServers is the maximum number of
11910 servers on an *inactive* server machine, but more will be forked
11911 off to handle unusually heavy loads (or unusually slow clients);
11912 these will die off when they are no longer needed --- without
11913 reverting to the overhead of full forking operation. There is a
11914 hard maximum of 150 server processes compiled in, largely to
11915 avoid forking out of control and dragging the machine down.
11916 (This is arguably too high).
11918 In my server endurance tests, this mechanism did not appear to
11919 impose any significant overhead, even after I forced it to put the
11920 scoreboard file on a normal filesystem (which might have more
11921 overhead than tmpfs). [Robert Thau]
11923 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
11926 *) Read .htaccess files even in directory with <Directory> section.
11927 (Former incompatibility noted on mailing list, now fixed). [Robert
11930 *) "HEAD /" gives the client a "Bad Request" error message, rather
11931 than trying to send no body *and* no headers. [Cliff Skolnick].
11933 *) Don't produce double error reports for some very obscure cases
11934 mainly involving auth configuration (the "all modules decline to
11935 handle" case which is a sure sign of a server bug in most cases,
11936 but also happens when authentication is badly misconfigured).
11939 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
11940 it's *for*, and this sort of thing really shouldn't be cluttering
11941 up the Makefile). [Robert Thau]
11943 *) Incidental code cleanups in http_main.c --- stop dragging
11944 sa_client around; just declare it where used. [Robert Thau]
11946 *) Another acc-related fix. (It doesn't like const char
11947 in some places...). [Mark Cox]
11949 Changes with Shambhala 0.6.1 13 Jul 1995
11951 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
11952 Also, fixed auth typo in http_protocol.c unmasked by this fix.
11954 *) Compiles clean with acc on SunOS [Paul Sutton]
11956 *) Reordered modules in modules.c so that Redirect takes priority
11957 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
11958 believe it or not, he has an actual site with a ScriptAlias and
11959 a Redirect declared for the *exact same directory*. Even *my*
11960 compatibility fetish wouldn't motivate me to fix this if the fix
11961 required any effort, but it doesn't, so what the hey.
11963 *) Fixed to properly default several server_rec fields for virtual
11964 servers from the corresponding fields in the main server_rec.
11965 [Cliff Skolnick --- 'port' was a particular irritant].
11967 *) No longer kills off nph- child processes before they are
11968 finished sending output. [Matthew Gray]
11970 Changes with Shambhala 0.6.0 10 Jul 1995
11972 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
11973 the connection to the client in an "aborted" state, but otherwise
11974 allow whatever handlers are running to clean up. hard_timeout()s
11975 abort the request in progress completely; anything not tied to some
11976 resource pool cleanup will leak. They're still around because I
11977 haven't yet come up with a more elegant way of handling
11978 timeouts when talking to something that isn't the client. The
11979 default_handler and the dir_handler now use soft timeouts, largely
11980 so I can test the feature. [Robert Thau]
11982 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
11983 the case of log handlers dying prematurely is probably handled VERY
11984 gracelessly at this point, and if the logger stops reading input,
11985 the server will hang. (It is known to correctly restart the
11986 logging process on server restart; this is (should be!) going through
11987 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
11988 script). [Robert Thau]
11990 *) asis files supported (new module). [Robert Thau]
11992 *) IdentityCheck code is compiled in, but has not been tested. (I
11993 don't know anyone who runs identd). [Robert Thau]
11995 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
11996 came in with the request, for NCSA bug-compatibility. [Robert Thau]
11998 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
12000 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
12001 as timeouts are not in scope. [Robert Thau]
12003 *) quoted-string args in config files now handled correctly (doesn't drop
12004 the last character). [Robert Thau; reported by Randy Terbush]
12006 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
12007 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
12009 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
12010 default default type); the former default default behavior when all
12011 type-checkers defaulted had been a core dump. [Paul Sutton]
12013 *) Copy filenames out of the struct dirent when indexing
12014 directories. (On Linux, readdir() returns a pointer to the same
12015 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
12017 Changes with Shambhala 0.5.3 [not released]
12019 *) Default response handler notes "file not found" in the error log,
12020 if the file was not found. [Cliff Skolnick].
12022 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
12023 code no longer sets up bogus PATH_INFO which fakes out the directory
12024 handler). [Cliff Skolnick]
12026 Changes with Shambhala 0.5.2 06 Jul 1995
12028 *) Changes to http_main.c --- root server no longer plays silly
12029 games with SIGCHLD, and so now detects and replaces dying
12030 children. Child processes just die on SIGTERM, without taking
12031 the whole process group with them. Potential problem --- if any
12032 child process refuses to die, we hang in restart.
12033 MaxRequestsPerChild may still not work, but it certainly works
12034 better than it did before this! [Robert Thau]
12036 *) mod_dir.c bug fixes: ReadmeName and HeaderName
12037 work (or work better, at least); over-long description lines
12038 properly terminated. [Mark Cox]
12040 *) http_request.c now calls unescape_url() more places where it
12041 should [Paul Sutton].
12043 *) More directory handling bugs (reported by Cox)
12044 Parent Directory link is now set correctly. [Robert Thau]
12046 Changes with Shambhala 0.5.1 04 Jul 1995
12048 *) Generalized cleanup interface in alloc.c --- any function can be
12049 registered with alloc.c as a cleanup for a resource pool;
12050 tracking of files and file descriptors has been reimplemented in
12051 terms of this interface, so I can give it some sort of a test.
12054 *) More changes in alloc.c --- new cleanup_for_exec() function,
12055 which tracks down and closes all file descriptors which have been
12056 registered with the alloc.c machinery before the server exec()s a
12057 child process for CGI or <!--#exec-->. CGI children now get
12058 started with exactly three file descriptors open. Hopefully,
12059 this cures the problem Rob H. was having with overly persistent
12060 CGI connections. [Robert Thau]
12062 *) Mutual exclusion around the accept() in child_main() --- this is
12063 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
12064 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
12065 This uses fcntl(F_SETLK,...) on the error log descriptor because
12066 flock() on that descriptor won't work on systems which have BSD
12067 flock() semantics, including (I think) Linux 1.3 and Solaris.
12069 This does work on SunOS (when the server is idle, only one
12070 process in the pool is waiting on accept()); it *ought* to work
12071 on the other systems. [Robert Thau]
12073 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
12075 *) sizeof(*sa_client) bugfix from [Rob Hartill]
12077 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
12079 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
12080 be unnecessary if I go to the revised timeout-handling scheme).
12083 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
12084 string) even if none came in with the request. [Robert Thau]
12086 *) CHANGES file added to distribution ;-).
12088 Changes with Shambhala 0.4.5
12090 *) mod_dld --- early dynamic loading support [rst]
12091 *) Add wildcard content handlers for XBITHACK; default_hander now
12092 invoked with that mechanism (as a handler hanging off mod_core) [rst]
12093 *) XBITHACK supported as a wildcard content-handler, and
12094 configurable at run-time (not just at compile time, as in the
12095 "patchy server" releases) [rst]
12097 Changes with Shambhala 0.4.4 30 Jun 1995
12099 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
12100 *) Handle Addtype x/y .z [rst, reported by Cox]
12102 Changes with Shambhala 0.4.3
12104 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
12105 synonymous [rst, terbush]
12107 Changes with Shambhala 0.4.1 28 Jun 1995
12109 *) First-cut virtual host implementation; some refit in the config
12110 reading code, and log management, was necessary to support this [rst]
12111 *) Sub-pool machinery, originally added to avoid excessive storage
12112 allocation on listings of large directories (which turned out to
12113 be the problem that the 0.3 storage accounting was added to
12114 find). Subrequests and mod_dir changed to use subpools. [rst]
12115 *) More memory debugging --- free list consistency checks. [rst]
12116 *) Added err_headers to request_rec, with support elsewhere [rst]
12117 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
12119 Changes with Shambhala 0.3 19 Jun 1995
12121 *) Switch ONE_PROCESS to a runtime command-line option (-X)
12122 *) Don't compile in mod_ai_backcompat by default
12123 *) Switch name of server from Apache to Shambhala in Makefile
12124 *) Add some accounting routines to track memory usage in the pools,
12127 Changes with Shambhala 0.2
12129 *) Set DOCUMENT_ROOT CGI variable
12130 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
12131 *) Add critical section protection to handling of cleanup structures
12133 *) Significant code reorg within the server core to group related
12134 functions together [rst]
12135 *) Correctly handle clients that hang up before sending any request
12137 *) Replace dying child processes. [rst]
12139 Changes with Shambhala 0.1 12 Jun 1995
12141 Major rewrite of the pre-existing "patchy server" codebase, by
12142 Robert Thau (rst). Significant portions of the server code, such
12143 as configuration-file handling and HTTP authentication support,
12144 were ripped out and rewritten from scratch. Code that was not
12145 completely rewritten was significantly altered.
12147 Major changes with this release include:
12149 *) Introduction of the module API; in request handling, the central
12150 machinery just dispatches to various modules, which actually do
12151 most of the work. Configuration handling is similar --- modules
12152 declare their own commands, and the central machinery just
12153 dispatches to them.
12155 API features from shambhala/0.1 were substantially unchanged in
12156 Apache 1.0 and 1.1. (1.0 API features not yet present in this
12157 release, such as wildcard handlers and subpools, were added in
12158 subsequent Shambhala releases, and were also generally rst's
12161 *) This release included the following modules:
12163 mod_access (access control --- allow and deny directives),
12164 mod_alias (Alias and Redirect commands),
12165 mod_auth (straight HTTP authentication, based on flat-files)
12166 mod_auth_dbm (same, with dbm files)
12167 mod_cgi (CGI scripts and, in this release, ScriptAlias)
12168 mod_common_log (CLF access logs; later renamed mod_log_common)
12169 mod_dir (directory indexing)
12170 mod_include (server-side includes)
12171 mod_mime (AddType directives)
12172 mod_negotiation (content negotiation)
12173 mod_userdir (support for users' public_html directories)
12175 It also included a mod_ai_backcompat, which was a private hack
12176 for back-compatibility with rst's own AI-lab servers.
12178 All of these modules were substantially complete, and functional
12179 or nearly so (a few, which implemented features not in use at
12180 Thau's site, required patches of a few lines).
12182 *) sub-request machinery, to allow modules to determine how other
12183 modules would assign MIME types to a given file, or optionally
12184 serve its content (this is heavily used by mod_dir, mod_include
12185 and mod_negotiation).
12187 *) Resource pool system for keeping track of memory allocated and
12188 files opened in service of a particular request. Much of the
12189 code in the modules (when they weren't rewrites) was adjusted to
12190 replace a pervasive convention of using fixed-size buffers on
12191 the stack with an equally pervasive convention of using memory
12192 allocated with palloc().
12194 *) Reorganization of data structures associated with a given
12195 request to eliminate use of global variables and the troublesome
12196 unmunge_name function (used in NCSA and early Apache releases to
12197 attempt to determine the URI which mapped to a given filename
12198 --- a difficult proposition, given that it is easy to produce
12199 setups in which multiple URIs map to the same file).
12201 *) Source files renamed and rearranged
12203 *) Very simple pre-forking behavior --- parent process forked off a
12204 fixed number of children, and then just waited for SIGHUP.
12206 *) Other more minor changes too numerous to list.
12208 This release included modified versions of a lot of code from the
12209 Apache 0.6.4 public release, plus an early pre-forking patch
12210 codeveloped by Robert Thau and Rob Hartill.
12212 Changes with Apache 0.7.3 20 Jun 1995
12214 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
12215 were incorporated by Rob Hartill on the main branch while Robert Thau
12216 worked on the Shambhala rewrite above. Most were merged into the
12217 Shambala architecture after Apache 0.8.0.
12219 Changes with Apache 0.6.4 13 May 1995
12221 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
12224 Changes with Apache 0.5.1 10 Apr 1995
12226 Changes with Apache 0.4 02 Apr 1995
12228 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
12231 Changes with Apache 0.3 24 Mar 1995
12233 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
12236 Changes with Apache 0.2 18 Mar 1995
12238 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
12239 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
12240 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
