1 Changes with Apache 2.1.0-dev
3 [Remove entries to the current 2.0 section below, when backported]
5 *) Log an error when requests for URIs which fail to map to a valid
6 filesystem name are rejected with 403. [Jeff Trawick]
8 *) Fix mod_info to use the real config file name, not the default
9 config file name. [Aryeh Katz <aryeh@secured-services.com>]
11 *) Fix a couple of AIX xlc_r compiler issues in the code I just
12 committed. [Paul J. Reder]
14 *) Modified the cache code to be header-location agnostic. Also
15 fixed a number of other cache code bugs related to PR 15852.
16 Includes a patch submitted by Sushma Rai <rsushma@novell.com>.
17 This fixes mod_mem_cache but not mod_disk_cache yet so I'm not
18 closing the PR since that is what they are using. [Paul J. Reder]
20 *) Switch to APR 1.0 API.
22 *) Fix mod_include's expression parser to recognize strings correctly
23 even if they start with an escaped token. [André Malo]
25 *) Major overhaul of mod_include's filter parser. The new parser code
26 is expected to be more robust and should catch all of the edge cases
27 that were not handled by the previous one. This includes a binary
28 incompatible change of mod_include's external API. [André Malo]
30 *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
31 PR 14223. [André Malo]
33 *) mod_log_config: Fix %b log format to write really "-" when 0 bytes
34 were sent (e.g. with 304 or 204 response codes). [Astrid Keßler]
36 *) mod_rewrite: Catch an edge case, where strange subsequent RewriteRules
37 could lead to a 400 (Bad Request) response. [André Malo]
39 *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously
40 the current rewrite state was just used as lookup path, which lead to
41 strange and often useless results. Related to PR 8493. [André Malo]
43 *) Change Listen directive to bind to all addresses when a hostname is
44 not specified. [Justin Erenkrantz]
46 *) Correct failure with Listen directives on machines with IPv6 enabled.
47 [Colm MacCárthaigh <colm@stdlib.net>, Justin Erenkrantz]
49 *) Fix a link failure in mod_ssl when the OpenSSL libraries contain
50 the ENGINE functions but the engine header files are missing.
53 *) mod_dav: Use bucket brigades when reading PUT data. This avoids
54 problems if the data stream is modified by an input filter. PR 22104.
55 [Tim Robbins <tim@robbins.dropbear.id.au>, André Malo]
57 *) mod_rewrite: RewriteRules in server context using the force
58 type feature [T=...] no longer disable MultiViews. [André Malo]
60 *) mod_rewrite: In external rewrite maps lookup keys containing
61 a newline now cause a lookup failure. PR 14453.
62 [Cedric Gavage <cedric.gavage@unixtech.be>, André Malo]
64 *) mod_rewrite: Allow piped rewrite logs to be relative to ServerRoot.
67 *) mod_authz_groupfile: Strip trailing spaces of group names. This
68 hopefully saves some hours of searching for typos. PR 12863.
71 *) Remove an extra bit of unnecessary code from the recently
72 committed fix for PR 13946 (in mod_rewrite). Reported by
73 Andre Malo. [Paul J. Reder]
75 *) mod_rewrite: fix a problem in the proxy support of mod_rewrite.
76 The broken code was inserting multiple "proxy:" fields in the
77 rewritten URIs. [PR: 13946]
78 [Submitted by: Eider Oliveira <eider@bol.com.br>]
79 [Updated and reviewed by: Paul J. Reder]
81 *) mod_actions: Propagate the handler name to the action script via
82 the REDIRECT_HANDLER environment variable. [André Malo]
84 *) mod_actions: Introduce the "virtual" modifier to the Action directive,
85 which allows the use of handlers for virtual locations. PR 8431.
88 *) mod_speling: Recognize AcceptPathInfo setting for the particular
89 location. Default is to reject path information. PR 21059.
92 *) mod_ext_filter: Add the ability to filter request bodies.
93 [Philipp Reisner <philipp.reisner@linbit.com>]
95 *) Correct the code in ap_check_cache_feshness to check max_age,
96 smax_age, and expires correctly. Patch submitted by Thomas
97 Castelle [Paul J. Reder]
99 *) mod_cgid: Restart the cgid daemon if it crashes. PR 19849
100 [Glenn Nielsen <glenn@apache.org>]
102 *) Fix some broken log messages in WinNT MPM.
103 [Juan Rivera <Juan.Rivera@citrix.com>]
105 *) Add support for IMT minor-type wildcards (e.g., text/*) to
106 ExpiresByType. PR#7991 [Ken Coar]
108 *) Ensure that ssl-std.conf is generated at configure time, and switch
109 to using the expanded config variables to work the same as
110 httpd-std.conf PR 19611
113 *) Fix a problem with namespace mappings being dropped in mod_dav_fs;
114 if any property values were set which defined namespaces these
115 came out mangled in the PROPFIND response. PR 11637.
116 [Amit Athavale <amit_athavale@persistent.co.in>]
118 *) prefork MPM: Use the right permissions for the directory created
119 for gprof support. [Jim Carlson <jcarlson@jnous.com>]
121 *) Fix the inability to log errors like exec failure in
122 mod_ext_filter/mod_cgi script children. This was broken after
123 such children stopped inheriting the error log handle.
126 *) Fix a compile failure with recent OpenSSL and picky compilers
127 (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
129 *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
130 the INCLUDE path to be defined properly.
131 PR 11310. [Geoff Thrope <geoff@geoffthorpe.net>]
133 *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
135 *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
136 autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc).
137 [Geoff Thorpe <geoff@geoffthorpe.net>]
139 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
140 [Ian Holsman, André Malo]
142 *) mod_negotiation: quality values are now parsed independent from
143 the current locale. level values are now really parsed as integers.
144 PR 17564. [André Malo]
146 *) Added the WindowsSocketsWorkaround directive for Windows NT/2000/XP
147 to work around problems with certain VPN and Firewall products that
148 have buggy AcceptEx implementations.
149 [Allan Edwards w/ suggestions from Bill Stoddard & Bill Rowe]
151 *) Extend mod_negotiation to evaluate the environment variables
152 no-gzip and gzip-only-text/html the same way as mod_deflate does.
155 *) mod_rewrite: Fix some problems reporting errors with mapping
156 programs (RewriteMap prg:/something). [Jeff Trawick]
158 *) Return 413 if chunk-ext-header is too long rather than reading from
159 the truncated line. PR 15857. [Justin Erenkrantz]
161 *) Allow restart of httpd to occur even with syntax errors in the config
162 file. PR 16813. [Justin Erenkrantz]
164 *) Use APR_LAYOUT instead of APACHE_LAYOUT in configure. PR 15679.
167 *) Remove files on 'make distclean' that should be. PR 15592.
170 *) Allow apachectl to perform status with links and elinks as well.
173 *) Extend the SetEnvIf directive to capture subexpressions of the
174 matched value. [André Malo]
176 *) mod_log_config change optional hook to return previous handler
179 *) Forward port of mod_actions' ability to handle arbitrary methods
180 with the Script directive. [André Malo]
182 *) Let suexec send a message to stderr, if it failed or its policy
183 was violated. This message appears in the error log and allows
184 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
186 *) Modify buildconf to copy all required files into httpd's tree.
187 [Thom May <thom@planetarytramp.net>]
189 *) Allow mod_dav to do weak entity comparison functions.
192 *) Move RFC 1413 ident requests from core to new module mod_ident.
195 *) Add mod_authz_owner - a forward port of "Require file-owner"
196 and "Require file-group", which was already present in version
199 *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
202 *) Replace some of the mutex locking in the worker MPM with
203 atomic operations for higher concurrency. [Brian Pane]
205 *) Allow 'make depend' to work with non-GCC compilers.
208 *) If an httpd.conf has commented out AddModule directives,
209 apxs -i -a will add an un-commented AddModule directive for
210 the new module, which breaks the config.
211 PR: 11212 [Joe Orton]
213 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
215 *) Move the check of the Expect request header field after the hook
216 for ap_post_read_request, since that is the only opportunity for
217 modules to handle Expect extensions. [Justin Erenkrantz]
219 *) Rewrite of aaa modules to an authn/authz model.
220 [Dirk-Willem van Gulik, Justin Erenkrantz]
223 [Apache 2.1.0-dev includes those bug fixes and changes with the
224 Apache 2.0.xx tree as documented, and except as noted, below.]
226 Changes with Apache 2.0.48
228 *) mod_ssl: Fix segfaults after renegotiation failure. PR 21370
229 [Hartmut Keil <Hartmut.Keil@adnovum.ch>]
231 *) mod_autoindex: If a directory contains a file listed in the
232 DirectoryIndex directive, the folder icon is no longer replaced
233 by the icon of that file. PR 9587.
234 [David Shane Holden <dpejesh@yahoo.com>]
236 *) Fixed mod_usertrack to not get false positive matches on the
237 user-tracking cookie's name. PR 16661.
238 [Manni Wood <manniwood@planet-save.com>]
240 *) mod_cache: Fix the cache code so that responses can be cached
241 if they have an Expires header but no Etag or Last-Modified
245 *) Modify ap_get_client_block() to note if it has seen EOS.
248 *) Fix a bug, where mod_deflate sometimes unconditionally compressed the
249 content if the Accept-Encoding header contained only other tokens than
250 "gzip" (such as "deflate"). PR 21523. [Joe Orton, André Malo]
252 *) Avoid an infinite recursion, which occured if the name of an included
253 config file or directory contained a wildcard character. PR 22194.
256 *) mod_ssl: Fix a problem setting variables that represent the
257 client certificate chain. PR 21371 [Jeff Trawick]
259 *) Unix: Handle permissions settings for flock-based mutexes in
260 unixd_set_global|proc_mutex_perms(). Allow the functions to be
261 called for any type of mutex. PR 20312 [Jeff Trawick]
263 *) ab: Work over non-loopback on Unix again. PR 21495. [Jeff Trawick]
265 *) Fix a misleading message from the some of the threaded MPMs when
266 MaxClients has to be lowered due to the setting of ServerLimit.
269 *) Lower the severity of the "listener thread didn't exit" message
270 to debug, as it is of interest only to developers. PR 9011
273 *) MPMs: The bucket brigades subsystem now honors the MaxMemFree setting.
274 [Cliff Woolley, Jean-Jacques Clar]
276 *) Install config.nice into the build/ directory to make
277 minor version upgrades easier. [Joshua Slive]
279 *) Fix mod_deflate so that it does not call deflate() without checking
280 first whether it has something to deflate. (Currently this causes
281 deflate to generate a fatal error according to the zlib spec.)
282 PR 22259. [Stas Bekman]
284 *) mod_ssl: Fix FakeBasicAuth for subrequest. Log an error when an
285 identity spoof is encountered.
288 *) mod_rewrite: Ignore RewriteRules in .htaccess files if the directory
289 containing the .htaccess file is requested without a trailing slash.
290 PR 20195. [André Malo]
292 *) ab: Overlong credentials given via command line no longer clobber
293 the buffer. [André Malo]
295 *) mod_deflate: Don't attempt to hold all of the response until we're
296 done. [Justin Erenkrantz]
298 *) Assure that we block properly when reading input bodies with SSL.
299 PR 19242. [David Deaves <David.Deaves@dd.id.au>, William Rowe]
301 *) Update mime.types to include latest IANA and W3C types. [Roy Fielding]
303 *) mod_ext_filter: Set additional environment variables for use by
304 the external filter. PR 20944. [Andrew Ho, Jeff Trawick]
306 *) Fix buildconf errors when libtool version changes. [Jeff Trawick]
308 *) Remember an authenticated user during internal redirects if the
309 redirection target is not access protected and pass it
310 to scripts using the REDIRECT_REMOTE_USER environment variable.
311 PR 10678, 11602. [André Malo]
313 *) mod_include: Fix a trio of bugs that would cause various unusual
314 sequences of parsed bytes to omit portions of the output stream.
315 PR 21095. [Ron Park <ronald.park@cnet.com>, André Malo, Cliff Woolley]
317 *) Update the header token parsing code to allow LWS between the
318 token word and the ':' seperator. [PR 16520]
319 [Kris Verbeeck <kris.verbeeck@advalvas.be>, Nicel KM <mnicel@yahoo.com>]
321 *) Eliminate creation of a temporary table in ap_get_mime_headers_core()
322 [Joe Schaefer <joe+gmane@sunstarsys.com>]
324 *) Added FreeBSD directory layout. PR 21100.
325 [Sander Holthaus <info@orangexl.com>, André Malo]
327 *) Fix NULL-pointer issue in ab when parsing an incomplete or non-HTTP
328 response. PR 21085. [Glenn Nielsen <glenn@apache.org>, André Malo]
330 *) mod_rewrite: Perform child initialization on the rewrite log lock.
331 This fixes a log corruption issue when flock-based serialization
332 is used (e.g., FreeBSD). [Jeff Trawick]
334 *) Don't respect the Server header field as set by modules and CGIs.
335 As with 1.3, for proxy requests any such field is from the origin
336 server; otherwise it will have our server info as controlled by
337 the ServerTokens directive. [Jeff Trawick]
339 Changes with Apache 2.0.47
341 *) SECURITY [CAN-2003-0192]: Fixed a bug whereby certain sequences
342 of per-directory renegotiations and the SSLCipherSuite directive
343 being used to upgrade from a weak ciphersuite to a strong one
344 could result in the weak ciphersuite being used in place of the
345 strong one. [Ben Laurie]
347 *) SECURITY [CAN-2003-0253]: Fixed a bug in prefork MPM causing
348 temporary denial of service when accept() on a rarely accessed port
349 returns certain errors. Reported by Saheed Akhtar
350 <S.Akhtar@talis.com>. [Jeff Trawick]
352 *) SECURITY [CAN-2003-0254]: Fixed a bug in ftp proxy causing denial
353 of service when target host is IPv6 but proxy server can't create
354 IPv6 socket. Fixed by the reporter. [Yoshioka Tsuneo
355 <tsuneo.yoshioka@f-secure.com>]
357 *) SECURITY [VU#379828] Prevent the server from crashing when entering
358 infinite loops. The new LimitInternalRecursion directive configures
359 limits of subsequent internal redirects and nested subrequests, after
360 which the request will be aborted. PR 19753 (and probably others).
361 [William Rowe, Jeff Trawick, André Malo]
363 *) core_output_filter: don't split the brigade after a FLUSH bucket if
364 it's the last bucket. This prevents creating unneccessary empty
365 brigades which may not be destroyed until the end of a keepalive
367 [Juan Rivera <Juan.Rivera@citrix.com>]
369 *) Add support for "streamy" PROPFIND responses.
370 [Ben Collins-Sussman <sussman@collab.net>]
372 *) mod_cgid: Eliminate a double-close of a socket. This resolves
373 various operational problems in a threaded MPM, since on the
374 second attempt to close the socket, the same descriptor was
375 often already in use by another thread for another purpose.
378 *) mod_negotiation: Introduce "prefer-language" environment variable,
379 which allows to influence the negotiation process on request basis
380 to prefer a certain language. [André Malo]
382 *) Make mod_expires' ExpiresByType work properly, including for
383 dynamically-generated documents. [Ken Coar, Bill Stoddard]
385 Changes with Apache 2.0.46
387 *) SECURITY [CAN-2003-0245]: Fixed a bug causing apr_pvsprintf() to crash
388 by sending an overly long string. This can be triggered remotely
389 through mod_dav, mod_ssl, and other mechanisms. Reported by David
390 Endler <DEndler@iDefense.com>.
391 [Joe Orton <jorton@redhat.com>]
393 *) SECURITY [CAN-2003-0189]: Fixed a denial-of-service vulnerability
394 affecting basic authentication on Unix platforms related to
395 thread-safety in apr_password_validate(). The problem was reported
396 by John Hughes <john.hughes@entegrity.com>.
398 *) Fix for mod_dav. Call the 'can_be_activity' callback, if provided,
399 when a MKACTIVITY request comes in.
400 [Ben Collins-Sussman <sussman@collab.net>]
402 *) Perform run-time query in apxs for apr and apr-util's includes.
405 *) run libtool from the apr install directory (in case that is different
406 from the apache install directory) [Jeff Trawick]
408 *) configure.in: Play nice with libtool-1.5. [Wilfredo Sanchez]
410 *) If mod_mime_magic does not know the content-type, do not attempt to
411 guess. PR 16908. [Andrew Gapon <agapon@telcordia.com>]
413 *) ssl session caching(shmht) : Fix a SEGV problem with SHMHT session
415 [Andreas Leimbacher <andreasl67@yahoo.de>, Madhusudan Mathihalli]
417 *) Add a delete flag to htpasswd.
420 *) Fix mod_rewrite's handling of absolute URIs. The escaping routines
421 now work scheme dependent and the query string will only be
422 appended if supported by the particular scheme. [André Malo]
424 *) Add another check for already compressed content in mod_deflate.
425 PR 19913. [Tsuyoshi SASAMOTO <nazonazo@super.win.ne.jp>]
427 *) Fixes for VPATH builds; copying special.mk and any future .mk files
428 from the source tree as well as the build tree (now creates a usable
429 configuration for apxs), and eliminated redundant -I'nclude paths.
432 *) Code fixes, constness corrections and ssl_toolkit_compat.h updates
433 for SSLC and OpenSSL toolkit compatibility. Still work remains to
434 be done to cripple features based on the limitations of RSA's binary
435 distribution of their SSL-C toolkit.
436 [William Rowe, Madhusudan Mathihalli, Jeff Trawick]
438 *) Linux 2.4+: If Apache is started as root and you code
439 CoreDumpDirectory, coredumps are enabled via the prctl() syscall.
442 *) ap_get_mime_headers_core: allocate space for the trailing null
443 when folding is in effect.
444 PR 18170 [Peter Mayne <PeterMayne@SPAM_SUX.ap.spherion.com>]
446 *) Fix --enable-mods-shared=most and other variants. [Aaron Bannert]
448 *) mod_log_config: Add the ability to log the id of the thread
449 processing the request via new %P formats. [Jeff Trawick]
451 *) Use appropriate language codes for Czech (cs) and Traditional Chinese
452 (zh-tw) in default config files. PR 9427. [André Malo]
454 *) mod_auth_ldap: Use generic whitespace character class when parsing
455 "require" directives, instead of literal spaces only. PR 17135.
458 *) Hook mod_rewrite's type checker before mod_mime's one. That way the
459 RewriteRule [T=...] Flag should work as expected now. PR 19626.
462 *) htpasswd: Check the processed file on validity. If a line is not empty
463 and not a comment, it must contain at least one colon. Otherwise exit
464 with error code 7. [Kris Verbeeck <Kris.Verbeeck@ubizen.com>, Thom May]
466 *) Fix a problem that caused httpd to be linked with incorrect flags
467 on some platforms when mod_so was enabled by default, breaking
468 DSOs on AIX. PR 19012 [Jeff Trawick]
470 *) By default, use the same CC and CPP with which APR was built.
471 The user can override with CC and CPP environment variables.
474 *) Fix ap_construct_url() so that it surrounds IPv6 literal address
475 strings with []. This fixes certain types of redirection.
476 PR 19207. [Jeff Trawick]
478 *) forward port of buffer overflow fixes for htdigest. [Thom May]
480 *) Added AllowEncodedSlashes directive to permit control of whether
481 the server will accept encoded slashes ('%2f') in the URI path.
482 Default condition is off (the historical behaviour). This permits
483 environments in which the path-info needs to contain encoded
484 slashes. PR 543, 2389, 3581, 3589, 5687, 7066, 7865, 14639. [Ken Coar]
486 *) When using Redirect in directory context, append requested query
487 string if there's no one supplied by configuration. PR 10961.
490 *) Unescape the supplied wildcard pattern in mod_autoindex. Otherwise
491 the pattern will not always match as desired. PR 12596.
494 *) mod_autoindex now emits and accepts modern query string parameter
495 delimiters (;). Thus column headers no longer contain unescaped
496 ampersands. PR 10880 [André Malo]
498 *) Enable ap_sock_disable_nagle for Windows. This along with the
499 addition of APR_TCP_NODELAY_INHERITED to apr.hw will cause Nagle
500 to be disabled for Windows. [Allan Edwards]
502 *) Correct a mis-correlation between mpm_common.c and mpm_common.h;
503 This patch reverts us to pre-2.0.46 behavior, using the
504 ap_sock_disable_nagle noop macro, because ap_sock_disable_nagle
505 was never compiled on Win32. [Allan Edwards, William Rowe]
507 *) Fix a build problem with passing unsupported --enable-layout
508 args to apr and apr-util. This broke binbuild.sh as well as
509 user-specified layout parameters. PR 18649 [Justin Erenkrantz,
512 *) If a Date response header was already set in the headers array,
513 this value was ignored in favour of the current time. This meant
514 that Date headers on proxied requests where rewritten when they
515 should not have been. PR: 14376 [Graham Leggett]
517 *) Add code to buildconf that produces an httpd.spec file from
518 httpd.spec.in, using build/get-version.sh from APR.
521 *) Fixed a segfault when multiple ProxyBlock directives were used.
522 PR: 19023 [Sami Tikka <sami.tikka@f-secure.com>]
524 *) SECURITY [CAN-2003-0134] OS2: Fix a Denial of Service vulnerability
525 identified and reported by Robert Howard <rihoward@rawbw.com> that
526 where device names faulted the running OS2 worker process.
527 The fix is actually in APR 0.9.4. [Brian Havard]
529 *) Forward port: Escape special characters (especially control
530 characters) in mod_log_config to make a clear distinction between
531 client-supplied strings (with special characters) and server-side
532 strings. This was already introduced in version 1.3.25.
535 *) mod_deflate: Check also err_headers_out for an already set
536 Content-Encoding: gzip header. This prevents gzip compressed content
537 from a CGI script from being compressed once more. PR 17797.
540 Changes with Apache 2.0.45
542 *) Fix possible segfaults under obscure error conditions within the
543 cgid daemon. [Jeff Trawick, William Rowe]
545 *) SECURITY [CAN-2003-0132]: Close a Denial of Service vulnerability
546 identified by David Endler <DEndler@iDefense.com> on all platforms.
547 An unlimited stream of newlines were acceptable between requests
548 where each <lf> would allocate an 80 byte buffer, leading very
549 quickly to memory exahustion. [Brian Pane]
551 *) Added an rpm build script.
552 [Graham Leggett, Joe Orton <jorton@redhat.com>]
554 *) Simpler, faster code path for request header scanning [Brian Pane]
556 *) SECURITY: Eliminated leaks of several file descriptors to child
557 processes, such as CGI scripts. This fix depends on the APR library
558 release 0.9.2 or later (0.9.3 was distributed with the httpd
559 source tarball for Apache 2.0.45.) PR 17206
560 [Christian Kratzer <ck@cksoft.de>, Bjoern A. Zeeb <bz@zabbadoz.net>]
562 *) Fix path handling of mod_rewrite, especially on non-unix systems.
563 There was some confusion between local paths and URL paths.
564 PR 12902. [André Malo]
566 *) Prevent endless loops of internal redirects in mod_rewrite by
567 aborting after exceeding a limit of internal redirects. The
568 limit defaults to 10 and can be changed using the RewriteOptions
569 directive. PR 17462. [André Malo]
571 *) Win32: Avoid busy wait (consuming all the CPU idle cycles) when
572 all worker threads are busy.
573 [Igor Nazarenko <igor_nazarenko@hotmail.com>]
575 *) Keep the subrequest filter in place when a subrequest is
576 redirected. PR 15423. [Jeff Trawick]
578 *) you can now specify the compression level for mod_deflate.
579 [Ian Holsman, Stephen Pierzchala <stephen@pierzchala.com>,
580 Michael Schroepl <Michael.Schroepl@telekurs.de>]
582 *) mod_deflate: Extend the DeflateFilterNote directive to
583 allow accurate logging of the filter's in- and outstream.

1151 Also Surfaced this directive in the standard config (default FULL)
1154 *) Change mod_rewrite to use apr-util's dbm support for dbm rewrite
1155 maps. The dbm type (e.g., ndbm, gdbm) can be specified on the
1156 RewriteMap directive. PR 10644 [Jeff Trawick]
1158 *) Fixed mod_rewrite's RewriteMap prg: support so that request/response

1173 [Ian Darwin <Ian779@darwinsys.com>]
1175 *) thread safety & proxy-ftp [Alexey Panchenko alexey@liwest.ru, Ian Holsman]
1177 *) mod_disk_cache works much better. This module should still
1178 be considered experimental. [Eric Prud'hommeaux]
1180 *) Performance improvement for keepalive requests: when setting
1181 aside a small file for potential concatenation with the next
1182 response on the connection, set aside the file descriptor rather
1183 than copying the file into the heap. [Brian Pane]
1185 *) Modified version check on openssl so that it finds the executable
1186 first and then performs a check of the version, only warning the
1187 user if they chose, or we selected, an old version of OpenSSL.
1188 This change also allows the code to work for non-openssl libraries
1189 selected via the --with-ssl=dir option, which can override the
1190 automated library check in any case. [Roy Fielding]
1192 Changes with Apache 2.0.40
1194 *) SECURITY [CAN-2002-0661] (cve.mitre.org):
1195 Close a very significant security hole that
1196 applies only to the Win32, OS2 and Netware platforms. Unix was not
1197 affected, Cygwin may be affected. Certain URIs will bypass security
1198 and allow users to invoke or access any file depending on the system
1199 configuration. Without upgrading, a single .conf change will close
1200 the vulnerability. Add the following directive in the global server
1201 httpd.conf context before any other Alias or Redirect directives;
1202 RedirectMatch 400 "\\\.\."
1203 Reported by Auriemma Luigi <bugtest@sitoverde.com>.
1206 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1207 Close a path-revealing exposure in multiview type
1208 map negotiation (such as the default error documents) where the
1209 module would report the full path of the typemapped .var file when
1210 multiple documents or no documents could be served based on the mime
1211 negotiation. Reported by Auriemma Luigi <bugtest@sitoverde.com>.
1214 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1215 Close a path-revealing exposure in cgi/cgid when we
1216 fail to invoke a script. The modules would report "couldn't create
1217 child process /path-to-script/script.pl" revealing the full path
1218 of the script. Reported by Jim Race <jrace@qualys.com>.
1221 *) Set aside the apr-iconv and apr_xlate() features for the Win32
1222 build of 2.0.40 so development can be completed. A patch, from
1223 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
1224 will be available for those that wish to work with apr-iconv.
1227 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
1228 chain. [Peter Van Biesen <peter.vanbiesen@vlafo.be>]
1230 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
1231 set to 1, so we can exclude things from the general case with
1232 browsermatch. [Ian Holsman, Andre Schild <A.Schild@aarboard.ch>]
1234 *) Accept multiple leading /'s for requests within the DocumentRoot.
1235 PR 10946 [William Rowe, David Shane Holden <dpejesh@yahoo.com>]
1237 *) Solved the reports of .pdf byterange failures on Win32 alone.
1238 APR's sendfile for the win32 platform collapses header and trailer
1239 buffers into a single buffer. However, we destroyed the pointers
1240 to the header buffer if a trailer buffer was present. PR 10781
1243 *) mod_ext_filter: Add the ability to enable or disable a filter via
1244 an environment variable. Add the ability to register a filter of
1245 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
1247 *) Restore the ability to specify host names on Listen directives.
1248 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh@yahoo.com>]
1250 *) When deciding on the default address family for listening sockets,
1251 make sure we can actually bind to an AF_INET6 socket before
1252 deciding that we should default to AF_INET6. This fixes a startup
1253 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
1255 *) Replace usage of atol() to parse strings when we might want a
1256 larger-than-long value with apr_atoll(), which returns long long.
1257 This allows HTTPD to deal with larger files correctly.
1258 [Shantonu Sen <ssen@apple.com>]
1260 *) mod_ext_filter: Ignore any content-type parameters when checking if
1261 the response should be filtered. Previously, "intype=text/html"
1262 wouldn't match something like "text/html;charset=8859_1".
1265 *) mod_ext_filter: Set up environment variables for external programs.
1266 [Craig Sebenik <craig@netapp.com>]
1268 *) Modified the HTTP_IN filter to immediately append the EOS (end of
1269 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
1270 the caller to determine that no content remains without prefetching
1271 additional POST body. [William Rowe]
1273 *) Get proxy ftp to work over IPv6. [Shoichi Sakane <sakane@kame.net>]
1275 *) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml@suse.de>]
1277 *) Update SuSE layout. [Peter Poeml <poeml@suse.de>]
1279 *) Changes to the internationalized error documents:
1280 Comment them out in the default config file to make the default
1281 install as simple as possible; Correct the english 500 error to
1282 be more understandable; Add a Swedish translation.
1283 [Thomas Sjogren <thomas@northernsecurity.net>,
1284 Erik Abele <erik@codefaktor.de>, Rich Bowen, Joshua Slive]
1286 *) Increase the limit on file descriptors per process in apachectl.
1289 *) Fix a dependency error when building ApacheMonitor, so that Win32
1290 and MSVC now trust that the project is current (when it is).
1291 [James Cox <imajes@php.net>]
1293 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
1294 [Arthur P. Smith <apsmith@aps.org>, Jeff Trawick]
1296 *) APR-Util Renames pending have been completed [Thom May]
1298 *) Performance improvements for the code that reads request
1299 headers (ap_rgetline_core() and related functions) [Brian Pane]
1301 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
1302 to configure the maximum amount of memory the allocators will
1303 hold on to for reuse. Anything over the MaxMemFree threshold
1304 will be free()d. This directive is useful when uncommon large
1305 peaks occur in memory usage. It should _not_ be used to mask
1306 defective modules' memory use. [Sander Striker]
1308 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
1309 scripts would not result in a truncated response.
1310 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
1312 *) Add a filter_init parameter to the filter registration functions
1313 so that a filter can execute arbitrary code before the handlers
1314 are invoked. This resolves a problem where mod_include requests
1315 would incorrectly return a 304. [Justin Erenkrantz]
1317 *) Fix a long-standing bug in 2.0, CGI scripts were being called
1318 with relative paths instead of absolute paths. Apache 1.3 used
1319 absolute paths for everything except for SuExec, this brings back
1320 that standard. [Ryan Bloom]
1322 *) Fix infinite loop due to two HTTP_IN filters being present for
1323 internally redirected requests. PR 10146. [Justin Erenkrantz]
1325 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
1328 *) Fix mod_ext_filter to look in the main server for filter definitions
1329 when running in a vhost if the filter definition is not found in
1330 the vhost. PR 10147 [Jeff Trawick]
1332 *) Support WinNT CGI invocation through ScriptInterpreterSource
1333 'registry' for script interpreter paths and names with non-ascii
1334 characters in the executable filepath. [William Rowe]
1336 *) Support the -w flag on to keep the Win32 console open on error.
1339 *) Normalize the hostname value in the request_rec to all-lowercase
1340 [Perry Harrington <pedward@webcom.com>]
1342 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
1343 extended characters (non US-ASCII) in non-utf8 format. This brings
1344 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
1345 to the cgi application itself. [William Rowe]
1347 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
1348 modules to bring them up to the current apr/apr-util APIs.
1351 *) Fix segfault in mod_mem_cache most frequently observed when
1352 serving the same file to multiple clients on an MP machine.
1355 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
1356 [Brian Degenhardt <bmd@mp3.com>, Ian Holsman]
1358 *) Fix perchild to work with apachectl by adding -k support to perchild.
1359 PR 10074 [Jeff Trawick]
1361 *) Fix a silly htpasswd.c logic error that incorrectly reported that
1362 both -c and -n had been used. PR 9989 [Cliff Woolley]
1364 *) Fixed a mod_include error case in which no HTTP response was sent
1365 to the client if an shtml document contained an unterminated SSI
1366 directive [Brian Pane]
1368 *) Improve ap_get_client_block implementation by using APR-util brigade
1369 helper functions and relying on current filter assumptions.
1372 Changes with Apache 2.0.39
1374 *) Fixed a build problem in htpasswd.c on Win32.
1375 [Guenter Knauf <eflash@gmx.net>, Cliff Woolley]
1377 Changes with Apache 2.0.38
1379 *) Rewrite htpasswd to use APR. The removes the annoying warning about
1380 tmpnam being unsafe. [Ryan Bloom]
1382 *) We must set the MIME-type for .shtml files to text/html if we want them
1383 to be parsed for SSI tags. Add the config for that to the default
1384 config file so that it is easier to enable .shtml parsing.
1385 [Dave Dyer <ddyer@real-me.net>]
1387 *) Fixed a problem with 'make install' on ReliantUnix.
1388 [Jean-frederic Clere <jfrederic.clere@fujitsu-siemens.com>]
1390 *) Make the default_handler catch all requests that aren't served by
1391 another handler. This also gets us to return a 404 if a directory
1392 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1393 loaded. [Justin Erenkrantz]
1395 *) Fixed the handling of nested if-statements in shtml files.
1396 PR 9866 [Brian Pane]
1398 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1399 into a directory different from the one that was configured. This
1400 also mirrors the root= feature from 1.3. We cannot use prefix=,
1401 because both APR and APR-util resolve their installation paths at
1402 configuration time. This means that there is no variable prefix
1403 to replace. [Andreas Hasenack <andreas@netbank.com.br>]
1405 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1406 These levels of AIX don't have a thundering herd problem with
1407 accept(). [Jeff Trawick]
1409 *) prefork MPM: Ignore mutex errors during graceful restart. For
1410 certain types of mutexes (particularly SysV semaphores), we
1411 should expect to occasionally fail to obtain or release the
1412 mutex during restart processing. [Jeff Trawick]
1414 *) Fix install-bindist.sh so that it finds any perl instead of just
1415 early perl 5.x versions. This is consistent with a build/install
1416 from source, and it allows the perl scripts installed by a bindist
1417 to work on systems with perl 5.6. [Jeff Trawick]
1419 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
1420 Tru64 (and probably some other platforms). [Jeff Trawick]
1422 *) Allow CGI scripts to return their Content-Length. This also fixes a
1423 hang on HEAD requests seen on certain platforms (such as FreeBSD).
1426 *) Added log rotation based on file size to the RotateLog support
1427 utility. [Brad Nicholes]
1429 *) Fix some casting in mod_rewrite which broke random maps.
1430 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
1432 Changes with Apache 2.0.37
1434 *) allow POST method over SSL when per-directory client cert
1435 authentication is used with 'SSLOptions +OptRenegotiate' enabled
1436 and a client cert was found in the ssl session cache.
1438 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
1439 session cache when there is no cert chain in the cache. prior to
1440 the fix this situation would result in a FORBIDDEN response and
1441 error message "Cannot find peer certificate chain"
1444 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
1445 one was already sent. PR 9644 [Jeff Trawick]
1447 *) Fix the display of the default name for the mime types config
1448 file. PR 9729 [Matthew Brecknell <mbrecknell@orchestream.com>]
1450 *) Fix the working directory *for WinNT/2K/XP services only* to
1451 change to the Apache directory (one level above the location
1452 of Apache.exe, in the case that Apache.exe resides in bin/.)
1453 Solves the case of ServerRoot /foo paths where /foo was not
1454 on the same drive as /winnt/system32. [William Rowe]
1456 *) Make 2.0's "AcceptMutex" startup message now "completely"
1457 match how 1.3 does it. [Jim Jagielski]
1459 *) Implement a fixed size memory cache using a priority queue
1462 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
1463 querying certain other variables from config_vars.mk. PR 9316
1466 *) Added the "detached" attribute to the cgi_exec_info_t internals
1467 so that Win32 and Netware won't create a new window or console
1468 for each CGI invoked. PR 8387
1469 [Brad Nicholes, William Rowe]
1471 *) Consolidated the command line parameters and attributes that are
1472 manipulated by the optional function ap_cgi_build_command() in
1473 mod_cgi into a single structure.
1476 *) Get rid of uninitialized value errors with "apxs -q" on certain
1477 variables. [Stas Bekman <stas@stason.org>]
1479 *) Fix apxs to allow it to work when the build directory is somewhere
1480 besides server-root/build. PR 8453
1481 [Jeff Trawick and a host of others]
1483 *) Allow ap_discard_request_body to be called multiple times in the
1484 same request. Essentially, ap_http_filter keeps track of whether
1485 it has sent an EOS bucket up the stack, if so, it will only ever
1486 send an EOS bucket for this request.
1487 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
1489 *) Remove all special mod_ssl URIs. This also fixes the bug where
1490 redirecting (.*) will allow an SSL protected page to be viewed
1491 without SSL. [Ryan Bloom]
1493 *) Fix the binary build install script so that the build logic
1494 created by "apxs -g" will work when the user has a binary
1495 build. [Jeff Trawick]
1497 *) Allow instdso.sh to work with full paths to the shared module.
1500 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
1501 in module for NetWare [Brad Nicholes]
1503 *) Changed cgi and piped log behavior to accept 65536 characters
1504 on Win32 (matching Linux) before deadlocking between outputing
1505 client stdin, slurping the output from stdout and then the stderr
1506 stream. PR 8179 [William Rowe]
1508 *) Fixed Win32 wintty.exe support to assure the window title is valid.
1509 Elimiates possible gpfault or garbage title without the -t option.
1512 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
1513 brigades and input filters. [Justin Erenkrantz]
1515 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
1516 body. [Justin Erenkrantz]
1518 *) NetWare: Piping log entries through RotateLogs using the
1519 CustomLogs directive is finally supported now that we have
1520 the pipes and spawning functionality working.

1535 *) Fix the TIME_* SSL var lookups to be threadsafe. PR 9469.
1538 *) Ensure that apr_brigade_write() flushes in all of the cases that
1539 it should to avoid conditions in some modules that could cause
1540 large amounts of data to be buffered. [Cliff Woolley]
1542 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
1543 stripping the content_type from cached responses.
1546 *) apachectl passes through any httpd options. Note: apachectl
1547 should be used in preference to httpd since it ensures that any
1548 appropriate environment variables have been set up.
1551 *) Fix the combination of mod_cgid, mod_setuexec, and mod_userdir.

1572 from working on Unix. [Jeff Trawick]
1574 *) Add "-k start|restart|graceful|stop" support to httpd for the Unix

1595 of Apache. [Jeff Trawick]
1597 *) Removed documentation references to the no-longer-supported
1598 "make certificate" feature of mod_ssl for Apache 1.3.x. Test
1599 certificates, if truly desired, can be generated using openssl
1600 commands. PR 8724. [Cliff Woolley]
1602 *) Remove SSLLog and SSLLogLevel directives in favor of having
1603 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
1605 *) OS/390: LIBPATH no longer has to be manually uncommented in
1606 envvars to get apachectl to set up httpd properly. [Jeff Trawick]
1608 *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
1609 may now be specified to the <File/Directory > container, rather
1610 than by vhost. [William Rowe]
1612 *) mod_isapi: Experimental support for faux async support for ISAPI

1615 *) mod_isapi: Major refactoring of the code to rely on apr internals
1616 rather than MS APIs (using our own mod_isapi.h headers for ISAPI
1617 symbol definitions.) [William Rowe]
1619 *) mod_isapi: Fixed the return string length from GetServerVariable
1620 callback, it was not including the trailing null in the consumed

1690 This left the user in an ambiguous state. PR 8320 [Paul J. Reder]
1692 *) Close sockets on worker MPM when doing a graceless restart.
1695 *) Reverted a minor optimization in mod_ssl.c that used the vhost ID
1696 as the session id context rather that a MD5 hash of that vhost ID,
1697 because it caused very long vhost id's to be unusable with mod_ssl.

1701 directive in the server-wide document. PR 8643. [Jeff Trawick]
1703 *) Fixed SHMCB session caching. [Aaron Bannert, Cliff Woolley]
1705 *) Synced with remaining changes from mod_ssl 2.8.8-1.3.24:
1706 - Avoid SIGBUS on sparc machines with SHMCB session caches
1707 - Allow whitespace between the pipe and the name of the
1708 program in SSLLog "| /path/to/program". [Cliff Woolley]
1710 *) Introduce mod_ext_filter and mod_deflate experimental modules
1711 to the Win32 build (zlib sources must be in srclib\zlib.)
1714 *) Changes to the worker MPM's queue management and thread
1715 synchronization code to reduce mutex contention [Brian Pane]
1717 *) Don't install *.in configuration files since we already install
1718 *-std.conf files. [Aaron Bannert]
1720 *) Many improvements to the threadpool MPM. [Aaron Bannert]
1722 *) Fix subreqs that are promoted via fast_redirect from having invalid
1723 frec->r structures. This would cause subtle errors later on in
1724 request processing such as seen in PR 7966. [Justin Erenkrantz]
1726 *) More efficient pool recycling logic for the worker MPM [Brian Pane]
1728 *) Modify the worker MPM to not accept() new connections until
1729 there is an available worker thread. This prevents queued
1730 connections from starving for processing time while long-running
1731 connections were hogging all the available threads. [Aaron Bannert]

1778 *) SECURITY: Added the APLOG_TOCLIENT flag to ap_log_rerror() to
1779 explicitly tell the server that warning messages should be sent
1780 to the client in addition to being recorded in the error log.
1781 Prior to this change, ap_log_rerror() always sent warning
1782 messages to the client. In one case, a faulty CGI script caused
1783 the server to send a warning message to the client that contained
1784 the full path to the CGI script. This could be considered a
1785 minor security exposure. [Bill Stoddard]
1787 *) mod_autoindex output when SuppressRules was specified would
1788 omit the first carriage return so the first item in the list
1789 would appear to the right of the column headings instead of

1802 clean up some stray files and symlinks that libtool leaves around
1803 on some platforms. This gets subversion building properly since
1804 it needed a re-link to be performed by libtool at install time,

1910 [Paul Reder, Brian Pane]
1912 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
1913 cause the Apache parent process to run in the foreground (similar to
1914 -DNO_DETACH except that it doesn't switch session ids).
1917 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
1918 for those platforms that support it. If using the default
1919 implementation, this is between pthread and sysvsem in priority.
1920 This implies it's the new default for Darwin. [Jim Jagielski]
1922 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
1923 environment variables in the envvars file. [Jeff Trawick]
1925 *) worker MPM: Don't create a listener thread until we have a worker

1927 to take over scoreboard slots from a previous generation, we'll be
1928 accepting connections we can't process yet. [Jeff Trawick]

1959 *) The old, legacy (and unused) code in which the scoreboard was totally
1960 and completely contained in a file (SCOREBOARD_FILE) has been
1961 removed. This does not affect scoreboards which are *mapped* to
1962 files using named-shared-memory. [Jim Jagielski]
1964 *) Change bucket brigades API to allow a "bucket allocator" to be
1965 passed in at certain points. This allows us to implement freelists
1966 so that we can stop using malloc/free so frequently.

2005 *) Fix a mod_cgid problem that left daemon processes stranded
2006 in some server restart scenarios. [Jeff Trawick]
2008 *) Added exp_foo and rel_foo variables to config_vars.mk for
2009 all Apache and Autoconf path variables (like --sysconfdir,
2010 --sbindir, etc). exp_foo is the "expanded" version, which means
2011 that all internal variable references have been interpolated.
2012 rel_foo is the same as $exp_foo, only relative to $prefix if they
2013 share a common path. [Aaron Bannert]
2015 *) Fix some restart/terminate problems in the worker MPM. Don't
2016 drop connections during graceful restart. [Jeff Trawick]
2018 *) Change the header merging behaviour in proxy, as some headers
2019 (like Set-Cookie) cannot be unmerged due to stray commas in

2101 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
2102 when reading from a remote HTTP server in proxy. [Graham Leggett]
2104 *) Modify receive/send loop in proxy_http and proxy_ftp so that
2105 should it be necessary, the remote server socket is closed before
2106 transmitting the last buffer (set by ProxyIOBufferSize) to the
2107 client. This prevents the backend server from being forced to hang
2108 around while the last few bytes are transmitted to a slow client.
2109 Fix the case where no error checking was performed on the final
2110 brigade in the loop. [Graham Leggett]
2112 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
2113 CacheMaxExpire and CacheDefaultExpire to use seconds rather than

2150 *) Change mod_ssl to always do a full startup/teardown on restarts.
2151 this allows mod_ssl to be added to a server that is already
2152 running and makes it possible to add/change certs/keys after the
2153 server has been started. [Doug MacEachern]
2155 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
2156 This pipe must be a bidirectional 'console' style relay, which
2157 mod_ssl prints all prompts to the pipe's stdin, and reads the
2158 passphrases from the pipe's stdout. [William Rowe]
2160 *) Fix bug where --sysconfdir and --localstatedir were being
2161 ignored. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
2164 *) Fix --enable-layout to work again. Caution: When specifying
2165 --enable-layout, common arguments like --prefix, --exec-prefix,

2167 used instead. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
2170 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides

2177 cruft in piped logs and rewritemap child processes.
2180 *) All instances of apr_lock_t have been removed and converted
2181 to one of the following new lock APIs: apr_thread_mutex.h,
2182 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
2183 use the apr_lock.h API, as the old API will soon be deprecated.

2201 *) Correct Win32 failure of mmap of a segment beyond start of the
2202 file; fixes large SSL and similar transfers. [William Rowe]
2205 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
2206 multi-process mode to not "daemonize" while detaching from the
2207 controlling terminal. This is necessary for Apache to work with
2208 process-management tools like AIX's "System Resource Controller"
2209 as well as Dan Bernstein's "daemontools".

2223 are now unmerged in the http proxy before being sent to the
2224 client. [Graham Leggett]
2226 *) Fix a problem with proxy where each entry of a duplicated
2227 header such as Set-Cookie would overwrite and obliterate the
2228 previous value of the header, resulting in multiple header
2229 values (like cookies) going missing.

2266 *) Implement new ScoreBoardFile directive logic. This affects how
2267 we create the scoreboard's shared memory segment. If the directive
2268 is present, a name-based segment is created. If the directive is
2269 not present, first an anonymous segment is created, and if that
2270 fails, a name-based segment is created from a file of the name
2271 DEFAULT_SCOREBOARD. This gives third-party applications the
2272 ability to access our scoreboard. [Aaron Bannert]
2274 *) Allow mod_deflate to work with non-GET requests and properly send
2275 Content-Lengths. [Sander Striker <striker@apache.org>]
2277 *) Fix ap_directory_merge() to correctly merge configs when there is
2278 no <Directory /> block. [Justin Erenkrantz, William Rowe]
2280 *) Remove spurious debug messsages that are normal under HTTP
2281 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
2283 *) Fix a bug in mod_cgid that would prevent proper shutdown death
2284 of the cgid process. [Aaron Bannert]
2286 *) Add signal handling back in to the worker MPM for the one_process
2287 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
2289 *) Performance: Reuse per-connection transaction pools in the
2290 worker MPM, rather than destroying and recreating them. [Brian Pane]
2292 *) Remove all signals from the worker MPM's child process. Instead,
2293 the parent uses the Pipe of Death for all communication with the
2294 child processes. [Ryan Bloom]
2296 Changes with Apache 2.0.32
2298 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
2299 default if the directive is not specified. This mirrors older
2300 behavior without changes to the httpd.conf. [William Rowe]
2302 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
2303 the service, mpm and logging code, and bugs in apr_file_open_stderr
2304 and apr_file_dup2 functions. Win2K/XP services have no handles
2305 associated for stdin/out/err, which caused unpredictable behavior
2306 in the prior release. [William Rowe, Bill Stoddard]
2308 *) Win32: simplify the Application Event Log messages, since there isn't
2309 likely to be 'more information in the error log' before an error log
2310 has been opened. [William Rowe]
2312 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
2313 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
2315 *) Win32: apache -k shutdown now behaves like apache -k stop.
2318 *) Fix prefork to not kill the parent if a child hits a resource shortage
2319 on accept(). [Greg Ames]
2321 *) Fix seg faults that occur when what should be the httpd request line
2322 starts with \r\n followed by garbage. [Greg Ames]
2324 *) Allow statically linked support binaries with the new
2325 --enable-static-support flag, and enable this behavior in
2326 the binbuild script. Also add a new --enable-static-htdbm
2327 flag. [Aaron Bannert]
2329 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
2330 do only one stat() call when generating the directory listings.
2333 *) Fix resolve_symlink to save the original symlink name if known.
2336 *) Be a bit more sane with regard to CanonicalNames. If the user has
2337 specified they want to use the CanonicalName, but they have not
2338 configured a port with the ServerName, then use the same port that
2339 the original request used. [Ryan Bloom and Ken Coar]
2341 *) In core_input_filter, check for an empty brigade after
2342 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
2343 client says it will post some data but we get FIN before any
2344 data arrives. [Jeff Trawick]
2346 *) Not being able to bind to the socket is a fatal error. We should
2347 print an error to the console, and return a non-zero status code.
2348 With these changes, all of the Unix MPMs do that correctly.
2351 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
2352 through to CGI scripts. PR 9163
2353 [Brian Reid <breid@customlogic.com>,
2354 Zvi Har'El <rl@math.technion.ac.il>]
2356 *) binbuild.sh: Make sure that we use the expat from our source
2357 tree so that there aren't any surprises on the target machine.
2360 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2361 enough to keep up with new requests. Start using
2362 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2363 when we can't talk to the daemon. [Jeff Trawick]
2365 *) apxs: LTFLAGS envvar can override default libtool options. Try
2366 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2367 the covers. [Jeff Trawick]
2369 *) The Location: response header field, used for external
2370 redirect, *must* be an absoluteURI. The Redirect directive
2371 tested for that, but RedirectMatch didn't -- it would allow
2372 almost anything through. Now it will try to turn an abs_path
2373 into an absoluteURI, but it will correctly varf like Redirect
2374 if the final redirection target isn't an absoluteURI. [Ken Coar]
2376 Changes with Apache 2.0.31
2378 *) Create the scoreboard (in the parent) in a global pool context,
2379 so it survives graceful restarts. This fixes a SEGV during
2380 graceful restarts. [Aaron Bannert]
2382 *) Add a timeout option to the proxy code 'ProxyTimeout'
2385 *) FTP directory listings are now always retrieved in ASCII mode.
2386 The FTP proxy properly escapes URI's and HTML in the generated
2387 listing, and escapes the path components when talking to the FTP
2388 server. It is now possible to browse the root directory by using
2389 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2390 Also, the last path component may contain wildcard characters
2391 '*' and '?', and if they do, a directory listing is created instead
2392 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2395 *) Added single-listener unserialized accept support to the
2396 worker MPM [Brian Pane]
2398 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2399 the incoming host header through to the proxied server
2400 [Geoff <g.russell@ieee.org>]
2402 *) New Directive Option for ProxyPass. It now can block a location
2403 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
2405 *) Don't let the default handler try to serve a raw directory. At
2406 best you get gibberish. Much worse things can happen depending
2407 on the OS. [Jeff Trawick]
2409 *) Change the pre_config hook to return a value. Modules can now emit
2410 an error message and then cause the server to quit gracefully during
2411 startup. This required a bump to the MMN. [Aaron Bannert]
2413 *) Fix some unix socket descriptor leaks in the handler side of
2414 mod_cgid (the part that runs in the server process). Whack a
2415 silly "close(-1)" in the handler too. [Jeff Trawick]
2417 *) Change the pre_mpm hook to return a value, so that scoreboard
2418 init errors percolate up to code that knows how to exit
2419 cleanly. This required a bump to the MMN. [Jeff Trawick]
2421 *) Add the socket back to the conn_rec and remove the create_connection
2422 hook. The create_connection hook had a design flaw that did not
2423 allow creating connections based on vhost info. [Bill Stoddard]
2425 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2426 Resolves the common case of using negotation to resolve the request
2427 /script/foo for /script.cgi/foo. [William Rowe]
2429 *) Added new functions ap_add_(input|output)_filter_handle to
2430 allow modules to bypass the usual filter name lookup when
2431 adding hard-coded filters to a request [Brian Pane]
2433 *) caching should now work on subrequests (still very experimental)
2436 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2438 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2441 *) Refactor ap_rgetline so that it does not use an internal brigade.
2442 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2444 *) Remove mod_auth_db. [Justin Erenkrantz]
2446 *) Do not install unnecessary pcre headers like config.h and internal.h.
2447 [Joe Orton <joe@manyfish.co.uk>]
2449 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
2450 (as it does for a normal request). quick_handled sub-requests now work
2451 in mod-include [Ian Holsman]
2453 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
2454 'CONTENT' one, as it needs to run AFTER all content headers
2456 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
2459 *) Split out blocking from the mode in the input filters.
2462 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
2464 *) Cause Win32 to capture all child-worker process errors in
2465 Apache to the main server error log, until the child can
2466 open its own error logs. [William Rowe]
2468 *) HPUX 11.*: Do not kill the child process when accept()
2469 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
2470 by [madhusudan_mathihalli@hp.com])
2473 *) Fix a problem in the parsing of the <Proxy foo> directive.
2476 *) rewrite of mod_ssl input filter for better performance and less
2477 memory usage [Doug MacEachern]
2479 *) allow quick_handler to be run on subrequests. [Ian Holsman]
2481 *) mod_dav now asks its provider to place content directly into the
2482 filter stack when handling a GET request. The mod_dav/provider
2483 API has changed, so providers need to be updated. [Greg Stein]
2485 *) Clear the output socket descriptor in unixd_accept() to make sure
2486 we don't supply a bogus socket to the caller if the accept fails.
2487 This caused problems with the worker MPM, which tried to process
2488 the returned socket if it was non-NULL. [Brian Pane]
2490 *) Move a check for an empty brigade to the start of core input filter
2491 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
2493 *) Add FileETag directive to allow configurable control of what
2494 data are used to form ETag values for file-based URIs. MMN
2495 bumped to 20020111 because of fields added to the end of
2496 the core_dir_config structure. [Ken Coar]
2498 *) Fix a segfault in mod_rewrite's logging code caused by passing the
2499 wrong config to ap_get_remote_host(). [Jeff Trawick]
2501 *) Allow mod_cgid to work from a binary distribution install by
2502 using 755 for the permissions on the log directory instead of
2505 *) Fixed a segfault that happened during graceful shutdown (or when
2506 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
2508 *) Split all Win32 modules [excluding the core components mod_core,
2509 mod_so, mod_win32 and the winnt mpm] into individual loadable
2510 modules, so the administrator may individually disable the former
2511 compiled-in modules by simply commenting out their LoadModule
2512 directives. [William Rowe]
2514 *) Saved Win32 module authors and porters many future headaches, by
2515 duplicating the appropriate .h files such as os.h into the include
2516 directory, including in the build tree. [William Rowe]
2518 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
2519 Use SSL functions/macros instead of directly dereferencing SSL
2520 structures wherever possible.
2521 Add type-casts for the cases where functions return a generic pointer.
2522 Add $SSL/include to configure search path.
2523 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2525 *) Moved several pointers out of the shared Scoreboard so it is
2526 more portable, and will present the vhost name across server
2527 generation restarts. [William Rowe]
2529 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
2532 Changes with Apache 2.0.30
2534 *) Fix the main bug for FreeBSD and threaded MPM's. There are
2535 still issues (see STATUS) but at least the server will now
2536 run without crashing the machine.
2537 [David Reid, Aaron Bannert, Justin Erenkrantz]
2539 *) Fix a typo in mod_deflate's m4 config section.
2540 [albert chin (china@thewrittenword.com)]
2542 *) Fix a couple of mod_proxy problems forwarding HTTP connections
2543 and handling CONNECT:
2544 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
2545 (2) Proxy failed to connect when the first IP address returned by
2546 the resolver was unreachable but a secondary IP address was.
2549 *) Fix the module identifer as shown in the docs for various core
2550 modules (e.g., the identifer for mod_log_config was previously
2551 listed as config_log_module). PR #9338
2552 [James Watson <ap2bug@sowega.org>]
2554 *) Fix LimitRequestBody directive by placing it in the HTTP
2555 filter. [Justin Erenkrantz]
2557 *) Fix mod_proxy seg fault when the proxied server returns
2558 an HTTP/0.9 response or a bogus status line.
2561 *) Prevent mod_proxy from truncating one character off the
2562 end of the status line returned from the proxied server.
2563 [Adam Sussman, Bill Stoddard]
2565 *) Eliminate loop in ap_proxy_string_read().
2566 [Adam Sussman, Bill Stoddard]
2568 *) Provide $0..$9 results from mod_include regex parsing.
2571 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
2573 *) Introduced the ForceLanguagePriority directive, to prevent
2574 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
2575 when using Multiviews. [William Rowe]
2577 *) Fix a problem which prevented mod_cgid and suexec from working
2578 together reliably [Greg Ames]
2580 *) Remove the call to exit() from within mod_auth_digest's post_config
2581 phase. [Aaron Bannert]
2583 *) Fix a problem in mod_auth_digest that could potentially cause
2584 problems with initialized static data on a system that uses DSOs.
2587 *) Fix a segfault in the worker MPM that could happen during
2588 child process exits. [Brian Pane, Aaron Bannert]
2590 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
2592 *) Fix matching of vhosts by ip address so we find IPv4
2593 vhost address when target address is v4-mapped form of
2594 that address. [Jeff Trawick]
2596 *) More performance tweaks to the BNDM string-search algorithm
2597 used to find "<!--#" tokens in mod_include [Brian Pane]
2599 *) Miscellaneous small performance fixes: optimized away various
2600 string copy operations and removed large temp buffers from
2601 the stack [Brian Pane]
2603 *) Fixed startup segfault that occurred when a VirtualHost
2604 directive had a port but no address [Brian Pane]
2606 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
2608 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
2609 if oslevel < WINNT. This should fix several problems reported
2610 Against 2.0.28 on Windows 98 [Bill Stoddard]
2612 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
2613 to fail. [Bill Stoddard]
2615 *) Change core code to allow an MPM to set hard thread/server
2616 limits at startup. prefork, worker, and perchild MPMs now have
2617 directives to set these limits. [Jeff Trawick]
2619 *) Win32: The async AcceptEx() event should be autoreset upon
2620 successful completion of a wait (WaitForSingleObject). This
2621 eliminates a number of spurious
2622 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
2625 *) Move any load library path environment variables out of
2626 apachectl and into a separate environment variable file which
2627 can be more easily tailored by the admin. The environment
2628 variable file as built by Apache may have additional system-
2629 specific settings. For example, on OS/390 we tailor the heap
2630 settings to allow lots of threads. [Jeff Trawick]
2632 *) Use the new APR pool code to reduce pool-related lock
2633 contention in the worker MPM. [Sander Striker]
2635 *) The POD no longer assumes the child is listening on 127.0.0.1
2636 and now pulls the first hostname in the list of listeners to
2637 perform the dummy connect on. This fixes a bug when the user
2638 had configured the Listen directive for an IP other than
2639 127.0.0.1. This would result in undead children and error
2640 messages such as "Connection refused: connect to listener".
2643 *) The worker MPM now respects the LockFile setting, needed to
2644 avoid locking problems with NFS. [Jeff Trawick]
2646 *) Fix segfault when worker MPM receives SIGHUP.
2647 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
2649 *) Fix bug that could potentially prevent the perchild MPM from
2650 working with more than one vhost/uid. [Aaron Bannert]
2652 *) Change make install and apxs -i processing of DSO modules to
2653 perform special handling on platforms where libtool doesn't install
2654 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
2655 which prevented standard LoadModule statements from working.
2658 *) Whenever mod_so is enabled (not just when there are DSOs for
2659 our modules), do whatever special magic is required for compiling/
2660 loading third-party modules. This allows third-party DSOs to
2661 be used on an AIX build when there were no built-in modules
2662 built as DSOs. (This should help on OS/390 and BeOS as well.)
2665 *) Allow apxs to be used to build DSOs on AIX without requiring the
2666 user to hard-code the list of import files. (This should help
2667 on OS/390 and BeOS as well.) [Jeff Trawick]
2669 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
2670 PR 8563, 8919 [William Rowe]
2672 *) Get binary builds working when libapr and libaprutil are built
2675 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
2676 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
2677 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
2679 *) Fix the handling of SSI directives in which the ">" of the
2680 terminating "-->" is the last byte in a file [Brian Pane]
2682 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
2683 message that we had back in apache-1.3 and still have scattered
2684 throughout our docs. [Aaron Bannert]
2686 *) Prevent the Win32 port from continuing after encountering an
2687 error in the command line args to apache. [William Rowe]
2689 *) On a error in the proxy, make it write a line to the error log
2692 *) Various mod_ssl performance improvements [Doug MacEachern]
2694 Changes with Apache 2.0.29
2696 *) Add buffering in core_output_filter to ensure that long
2697 lists of small buckets don't cause small packet writes.
2698 [Brian Pane, Ryan Bloom]
2700 *) Fix the installation target to make sure that the manual is
2701 installed in the correct location.
2702 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
2703 Gomez Henri <hgomez@slib.fr>]
2705 *) Fix the cmd command for mod_include. When we are processing
2706 a cmd command, we do not want to use the r->filename to set
2707 the command name. The command comes from the SSI tag. To do this,
2708 I added a variable to the function that builds the command line
2709 in mod_cgi. This allows the include_cmd function to specify
2710 the command line itself. [Ryan Bloom]
2712 *) Change open_logs hook to return a value, allowing you
2713 to flag a error while opening logs
2714 [Ian Holsman, Doug MacEachern]
2716 *) Change post_config hook to return a value, allowing you
2717 to flag a error post config
2718 [Ian Holsman, Jeff Trawick]
2720 *) Allow SUEXEC_BIN (the path to the suexec binary that is
2721 hard-coded into the server) to be specified to the configure
2722 script by the --with-suexec-bin parameter. [Aaron Bannert]
2724 *) Fix segv in worker MPM following accept on pipe-of-death
2727 *) Add mod_deflate to experimental.
2728 [Ian Holsman, Justin Erenkrantz]
2730 *) Bail out at configure time if an invalid MPM was specified.
2731 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2733 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
2734 configured [John Sterling <sterling@covalent.net>]
2736 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
2738 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
2740 *) Optimization for the BNDM string-search function in
2741 mod_include. [Brian Pane]
2743 *) Fixed the behavior of the XBitHack directive.
2744 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
2746 *) The threaded MPM for Unix has been removed. Use the worker
2747 MPM instead. [various]
2749 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
2750 in logging the error from a failed DNS lookup. [Jeff Trawick]
2752 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
2755 *) Get mod_cgid killed when a MPM exits due to a fatal error.
2758 *) Fix a file descriptor leak in mod_include. When we include a
2759 file, we use a sub-request, but we didn't destroy the sub-request
2760 immediately, instead we waited until the original request was
2761 done. This patch closes the sub-request as soon as the data is
2762 done being generated. [Brian Pane <bpane@pacbell.net>]
2764 *) Allow modules that add sockets to the ap_listeners list to
2765 define the function that should be used to accept on that
2766 socket. Each MPM can define their own function to use for
2767 the accept function with the MPM_ACCEPT_FUNC macro. This
2768 also abstracts out all of the Unix accept error handling
2769 logic, which has become out of synch across Unix MPMs.
2772 *) Fix a bug which would cause the response headers to be omitted
2773 when sending a negotiated ErrorDocument because the required
2774 filters were attached to the wrong request_rec.
2775 [John Sterling <sterling@covalent.net>]
2777 *) Remove commas from the end of the macros that define
2778 directives that are used by MPMs. Prior to this patch,
2779 you would use these macros without commas, which was unlike
2780 the macros for any other directives. Now, the caller provides
2781 the comma rather than the macro providing it. This makes
2782 the macros look more like the rest of the directives.
2783 [Ryan Bloom and Cliff Woolley]
2785 *) Add 'redirect-carefully' environment option to disable sending
2786 redirects under special circumstances. This is helpful for
2787 Microsoft's WebFolders when accessing a directory resource via
2788 DAV methods. [Justin Erenkrantz]
2790 *) Begin to abstract out the underlying transport layer.
2791 The first step is to remove the socket from the conn_rec,
2792 the server now lives in a context that is passed to the
2793 core's input and output filters. This forces us to be very
2794 careful when adding calls that use the socket directly,
2795 because the socket isn't available in most locations.
2798 *) Really reset the MaxClients value in worker and threaded
2799 when the configured value is not a multiple of the number
2800 of threads per child. We said we did previously but we
2801 forgot to. [Jeff Trawick]
2803 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
2805 *) If shared modules are requested and mod_so is not available,
2806 produce a fatal config-time error. [Justin Erenkrantz]
2808 *) Improve http2env's performance by cutting the work it has to
2809 do. [Brian Pane <bpane@pacbell.net>]
2811 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
2812 [Brian Pane <bpane@pacbell.net>]
2814 Changes with Apache 2.0.28
2816 *) Fix infinite loop in mod_cgid.c.
2817 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
2819 *) When no port is given in a "ServerName host" directive, the
2820 server_rec->port is now set to zero, not 80. That allows for
2821 run-time deduction of the correct server port (depending on
2822 SSL/plain, and depending also on the current setting of
2823 UseCanonicalName). This change makes redirections
2824 work, even with https:// connections. As in Apache-1.3, the
2825 connection's actual port number is never used, only the ServerName
2826 setting or the client's Host: setting. Documentation updated
2827 to reflect the change. [Martin Kraemer]
2829 *) Add a '%{note-name}e' argument to mod-headers, which works in
2830 the same way as mod_log_confg. [Ian Holsman]
2832 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
2833 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
2834 MPMs. [Cliff Woolley]
2836 *) Introduce htdbm, a user management utility for db/dbm authorization
2837 databases. [Mladen Turk <mturk@mappingsoft.com>]
2839 *) Optimize usage of strlen and strcat in ap_directory_walk.
2840 [Brian Pane <bpane@pacbell.net>]
2842 Changes with Apache 2.0.27
2844 *) Introduce an Apache mod_ssl initial configuration template
2845 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
2847 *) Fixed a memory leak in the getline parsing code that could
2848 be triggered by arbitrarily large header lines. Requests
2849 from the core input filter for single lines are now limited
2850 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
2852 *) Fix a truncation bug in how we print the port on the Via: header.
2853 The routine that prints the Via: header now takes a length for
2854 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
2856 *) Some syntax errors in mod_mime_magic's magic file can result
2857 in a 500 error, which previously was unlogged. Now we log the
2858 error. [Jeff Trawick]
2860 *) Add the support/checkgid helper app, which checks the run-time
2861 validity of group identifiers usable in the Group directive.
2864 *) Various --enable-so options have been fixed: --enable-so is
2865 treated as "static"; explicit --enable-so=shared issues an error;
2866 and explicit --enable-so fails with error on systems without
2867 APR_HAS_DSO. [Aaron Bannert]
2869 *) Fix a segfault in the core input filter when the client socket
2870 gets disconnected unexpectedly. [Cliff Woolley]
2872 *) Fix the reporting for child processes that die. This removes
2873 all of the non-portable W* macros from Apache.
2874 [Jeff Trawick and Ryan Bloom]
2876 *) Win32: Track and display "Parent Server Generation:" in
2877 mod_status output. The generation will be bumped at
2878 server graceful restart, when the child process exits
2879 by hitting MaxRequestsPerChild or if the child
2880 process exits abnormally. [Bill Stoddard]
2882 *) Win32: Fix problem where MaxRequestsPerChild directive was
2883 not being picked up in favor of the default. Enable
2884 the parent to start up a new child process immediately upon
2885 the old child starting shutdown.
2888 *) Fix some bungling of the remote port in rfc1413.c so that
2889 IdentityCheck retrieves the proper user id instead of failing
2890 and thus always returning "nobody."
2891 [Dick Streefland <Dick.Streefland@xs4all.nl>]
2893 *) Introduced thread saftey for mod_rewrite's internal cache.
2894 [Brian Pane <bpane@pacbell.net>]
2896 *) Simplified mod_env's directives to behave as most directives are
2897 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
2898 directive following that UnsetEnv within the same container.
2899 Also provides a runtime startup warning if a PassEnv configured
2900 environment value is undefined. [William Rowe]
2902 *) The worker MPM is now completely ported to APR's new lock API. It
2903 uses native APR types for thread mutexes, cross-process mutexes,
2904 and condition variables. [Aaron Bannert]
2906 *) Sync up documentation to remove all references to the now deprecated
2907 Port directive. [Justin Erenkrantz]
2909 *) Moved all ldap modules from the core to httpd-ldap sub-project
2912 *) Exit when we can't listen on any of the configured ports. This
2913 is the same behavior as 1.3, and it avoids having the MPMs to
2914 deal with bogus ap_listen_rec structures. [Jeff Trawick]
2916 *) Cleanup the proxy code that creates a request to the origin
2917 server. This change adds an optional hook, which allows modules
2918 to gain control while the request is created if the proxy module
2919 is loaded. The purpose of this hook is to allow modules to add
2920 input and/or output filters to the request to the origin. While
2921 I was at it, I made the core use this hook, so that proxy request
2922 creation uses some of the code from the core. This can still be
2923 greatly improved, but this is a good start. [Ryan Bloom]
2925 Changes with Apache 2.0.26
2927 *) Port the MaxClients changes from the worker MPM to the threaded
2930 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
2931 with the new input filtering system. [Justin Erenkrantz]
2933 *) Introduce the MultiviewsMatch directive, to allow the operator
2934 to be flexible in recognizing Handlers and Filters filename
2935 extensions as part of the Multiviews matching logic, strict with
2936 MultiviewsMatch NegotiatedOnly to accept only filename extentions
2937 that designate negotiated parameters, (content type, charset, etc.)
2938 or MultiviewsAll for the 1.3 behavior of matching any files, even
2939 if they have unregistered extensions. [William Rowe]
2941 *) Fixed the configure script to add a LoadModule directive to
2942 the default httpd.conf for any module that was compiled
2943 as a DSO. [Aaron Bannert <aaron@clove.org>]
2945 *) rewrite mod_ssl input filtering to work with the new input filtering
2946 system. [Justin Erenkrantz]
2948 *) prefork: Don't segfault when we are able to listen on some but
2949 not all of the configured ports. [Jeff Trawick]
2951 *) Build mod_so even if no core modules are built shared.
2952 [Aaron Bannert <aaron@clove.org>]
2954 *) Introduce ap_directory_walk rewrite (with further optimizations
2955 required) to adapt to the ap_process_request_internal() changes.
2956 Optimized so subrequests and redirects now reuse previous section
2957 merges, until we mismatch with the original directory_walk, and
2958 precomputed r->finfo results will cause directory_walk to skip
2959 the most expensive phases of the function. [William Rowe]
2961 *) Allow ApacheMonitor to connect to and control Apache on other
2962 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
2964 *) Remove the Port directive. In it's place, the Listen directive
2965 is now a required directive, which tells Apache what port to
2966 listen on. The ServerName directive has also been extended
2967 to accept an optional port. If the port is specified to the
2968 ServerName, the server will report that port whenever it
2969 reports the port that it is listening on. This change was
2970 made to ease configuration errors that stem from having a Port
2971 directive, and a Listen directive. In that situation, the server
2972 would only listen to the port specified by the Listen command,
2973 which caused a lot of confusion to users. [Ryan Bloom]
2975 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
2976 build, as loadable modules. [William Rowe]
2978 *) Fix --enable-mods-shared processing. If most is specified,
2979 then all modules that can be compiled as shared modules are.
2980 [Aaron Bannert <aaron@clove.org>]
2982 *) Update the mime.types file to map video/vnd.mpegurl to mxu
2983 and add commonly used audio/x-mpegurl for m3u extensions.
2984 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
2986 *) Eliminate the depreciated r->content_language, in favor of the array
2987 r->content_languages introduced many years ago. Module authors must
2988 substantially overhaul their modules, so this needs to be upgraded
2989 if the module still relied on backwards-brokeness. [William Rowe]
2991 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
2994 *) Rewrite the input filtering mechanisms to consolidate and reorganize
2995 code. In short, core_input_filter does something now and
2996 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
2998 *) Update the Win32 build to re-absorb mod_proxy and family.
3001 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
3002 current SDK.) [William Rowe]
3004 *) Some style changes to the code that does ProxyErrorOverride. Fixed
3005 config merge behaviour. [Graham Leggett]
3007 *) Allow support programs to be compiled against a static version
3008 of libapr. This allows the smaller support programs to be
3009 relocated. [Aaron Bannert <aaron@clove.org>]
3011 *) Update the mime.types file to the registered media types as
3012 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
3014 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
3015 number of clients that can connect at the same time, instead of
3016 specifying the maximum number of child processes.
3017 [Aaron Bannert <aaron@clove.org>]
3019 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
3020 be consistent with 1.3. [Justin Erenkrantz]
3022 *) Cache apr_explode_localtime() value for 15 seconds.
3023 [Brian Pane <bpane@pacbell.net>]
3025 *) Fix mod_include to not return ETag or Last-Modified headers.
3026 [Ian Holsman <ianh@cnet.com>]
3028 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
3030 *) Eliminate the wasteful run-time conversion of method names from strings
3031 to numbers in places where the methods are known at compile time.
3032 [Brian Pane <bpane@pacbell.net>]
3034 *) Turn the worker MPM's queue into a LIFO. This may
3035 improve cache-hit performance under some conditions.
3036 [Aaron Bannert <aaron@clove.org>]
3038 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
3039 support it. [Justin Erenkrantz]
3041 *) Cleanup the worker MPM. We no longer re-use transaction
3042 pools. This incurs less overhead than shuffling the pools
3043 around so that they can be re-used. Remove one of the
3044 queue's condition variables. We just redefined the API to
3045 state that you can't try to add more stuff than you allocated
3046 segments for. [Aaron Bannert <aaron@clove.org>]
3048 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
3050 *) Fixed persistent connections when a request contains a body.
3053 *) mod_dav uses a new API to speak to the backend provider for dead
3054 property management. [Greg Stein]
3056 *) Remove the Win32 script-processing exception from mod_cgi, and
3057 roll build_command_line/build_argv_list into a unified, overrideable
3058 ap_cgi_build_command optional function. [William Rowe]
3060 *) Rewrite find_start_sequence to use a better search algorithm
3061 to find the start tag. [Justin Erenkrantz]
3063 *) Fix a seg fault in mod_include. When we are generating an
3064 internal redirect, we must set r->uri to "", not a bogus
3065 string, and not NULL. [Ryan Bloom]
3067 *) Optimized location_walk, so subrequests, redirects and second passes
3068 now reuse previous section merges on a <Location > by <Location >
3069 basis, until we mismatch with the original location_walk.
3072 *) Back out the 1.45 change to util_script.c. This change made
3073 us set the environment variable REQUEST_URI to the redirected
3074 URI, instead of the originally requested URI.
3075 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3077 *) Make mod_include do lazy evaluation of potentially expensive to
3078 compute variables. [Brian Pane <bpane@pacbell.net>]
3080 *) Fix logging of bytes sent for HEAD requests. %b and %B should
3081 log either - or 0, before this patch, they were both logging
3082 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3084 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
3085 than per character. [Brian Pane <bpane@pacbell.net>]
3087 *) Normalize the primary request, redirects and sub-requests to
3088 run the same ap_process_request_internal for consistency in
3089 robustness, behavior and security. [William Rowe]
3091 *) Fix a segfault with mod_include when r->path_info is not set
3092 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
3094 *) Add -X functionality back. This indicates to all MPMs and any other
3095 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
3097 *) Some initial support for the cygwin platform [prefork only].
3098 This is not to be confused with support for the WinNT/Win32
3099 platform, which is the recommended configuration for native
3100 Win32 users. The cygwin platform support is recommended for
3101 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
3103 *) Changed syntax of Set{Input|Output}Filter. The list of filters
3104 must be semicolon delimited (if more than one filter is given.)
3105 The Set{Input|Output}Filter directive now overrides a parent
3106 container's directive (e.g. SetInputFilter in <Directory /web/foo>
3107 will override any SetInputFilter directive in <Directory /web>.)
3108 This new syntax is more consistent with Add{Input|Output}Filter
3109 directives defined in mod_mime. Also cures a bug in prior releases
3110 where the Set{Input|Output}Filter directive would corrupt the
3111 global configuration if the multiple directives were nested.
3114 *) Cured what's ailed mime for quite some time. If an AddSomething
3115 was given in the configuration (Language, Charset, Handler or
3116 Encoding) Apache would set the content type as given by AddType,
3117 but refused to check the mime.types file if AddType wasn't given
3118 for that specific extension. Setting the AddHandler for .html
3119 without setting the AddType text/html html would cause Apache to
3120 use the default content type. [William Rowe]
3122 *) Added some bulletproofing to memory allocation in the LDAP cache
3123 code. [Graham Leggett]
3125 Changes with Apache 2.0.25
3127 *) Move the installed /manual directory out of the /htdocs/ tree, so
3128 that it can be kept more independently from the remaining document
3129 root. The "Alias /manual ..." already allowed for easy projection
3130 into existing private document trees. [Martin Kraemer]
3132 *) Add specified user attributes to the environment when using
3133 mod_auth_ldap. This allows you to use mod_include to embed specified
3134 user attributes in a page like so:
3135 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
3138 *) Fix a performance problem with the worker MPM. We now create
3139 transaction pools once, and re-use them for each connection.
3140 [Aaron Bannert <aaron@clove.org>]
3142 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
3143 of a 'handler' or 'filter', so that any filename extension that does
3144 not contribute to the negotiated metadata can't be served without
3145 an explicit request. E.g., if the .Z extension is associated with
3146 an unzip filter, the user request somefile.Z.html, mod_negotiation
3147 won't serve it. It can serve somefile.Z.html when somefile.Z is
3148 requested, since the .Z extension is explictly requested, if the
3149 .html extension is associated with ContentType text/html.
3152 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
3153 and corresponding AddOutputFilter syntax, to insert one or more
3154 filters by mod_mime filename extension processing.
3157 *) Fix a growing connection pool in core_output_filter() for
3158 keepalive requests. [Jeff Trawick]
3160 *) Moved split_and_pass_pretag_buckets back to being a
3161 macro at Ryans's request. Removed the return from it
3162 by setting and returning a return code instead. Updated
3163 the code to check the return code from the macro and
3164 do the right thing. [Paul J. Reder]
3166 *) Fix a segfault when a numeric value was received for Host:.
3169 *) Add a function ap_remove_input_filter. This is to match
3170 up with ap_remove_output_filter. [Ryan Bloom]
3172 *) Clean up location_walk, so that this step performs a minimum
3173 amount of redundant effort (it must be run twice, but it will no
3174 longer reparse all <Location > blocks when the request uri
3175 hadn't changed.) [William Rowe]
3177 *) Eliminate proxy: (and all other 'special') processing from the
3178 ap_directory_walk() phase. Modules that want to use special
3179 walk logic should refer to the mod_proxy map_to_location example,
3180 with it's proxy_walk and proxysection implementation. This makes
3181 either directory_walk flavor much more legible, since that phase
3182 only runs against real <Directory > blocks.
3185 *) SECURITY: Fix a security problem in mod_include which would allow
3186 an SSI document to be passed to the client unparsed.
3187 [Cliff Woolley, Brian Pane]
3189 *) Introduce the map_to_storage hook, which allows modules to bypass
3190 the directory_walk and file_walk for non-file requests. TRACE
3191 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
3192 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
3195 *) Add the ability for mod_include to add the INCLUDES filter
3196 if the file is configured for the server-parsed handler.
3197 This makes the configuration for .shtml files much easier
3198 to understand, and allows mod_include to honor Apache 1.3
3199 config files. Based on Doug MacEachern's patch to PHP
3200 to do the same thing. [Ryan Bloom]
3202 *) force OpenSSL to ignore process local-caching and to always
3203 get/set/delete sessions using mod_ssl's callbacks
3204 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
3205 Geoff Thorpe <geoff@geoffthorpe.net>]
3207 *) Make the worker MPM shutdown and restart cleanly. This also
3208 cleans up some race conditions, and gets the worker using
3209 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
3211 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
3213 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
3215 *) Fix for mod_include. Ryan's patch to check error
3216 codes put a return in the wrong place. Also, the
3217 include handler return code wasn't being checked.
3218 I don't like macros with returns, so I converted
3219 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
3220 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3222 *) fix segv in mod_mime if no AddTypes are configured
3223 [John Sterling <sterling@covalent.net>]
3225 *) Enable ssl client authentication at SSL_accept time
3226 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
3228 *) Fix a segfault in mod_include when the original request has no
3229 associated filename (e.g., we're filtering the error document for
3230 a bad URI). [Jeff Trawick]
3232 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
3234 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
3235 of httpd is started and shuts down due to socket conflict. Moving the
3236 call to ap_log_pid solves the problem.
3238 *) Changed the late-1.3 log_config substitution %c to %X, to log the
3239 status of the closed connection, as it conflicts with the far more
3240 common, historical ssl logging directive %...{var}c. [William Rowe]
3242 *) Added the common error/ tree to the build/install targets
3243 (similar to the common icons/ tree) for the multi-language error
3244 messages that Lars committed earlier. [William Rowe]
3246 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
3248 *) Added a default commented-out mod_ldap and mod_auth_ldap
3249 configuration to httpd-std.conf and httpd-win.conf
3252 *) Added documentation for mod_ldap and mod_auth_ldap.
3255 *) Enabled negative caching on attribute comparisons in the LDAP cache.
3256 Fixed a problem where the default cache TTL was set in milliseconds
3257 not microseconds causing the cache to time out almost immediately.
3260 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
3261 module code to follow APR. [Graham Leggett]
3263 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
3264 cleaned up when the connection pool pool is cleaned up.
3267 *) Fix a minor issue with Jeff Trawick's mod_include
3268 patch. Without this patch, the code will just allocate
3269 more bytes in get_combined_directive than are needed.
3272 *) Added the LDAP authentication module mod_auth_ldap.
3273 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
3275 *) Added the LDAP cache and connection pooling module mod_ldap.
3276 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
3278 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
3279 by allowing a module to disable itself if its prerequisites are not
3280 met. [Justin Erenkrantz]
3282 Changes with Apache 2.0.24
3284 *) Fix a couple of issues in mod_include when the tag appeared at
3285 offsets near 8192 in the file being parsed. [Jeff Trawick]
3287 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
3288 reached. [Jeff Trawick]
3290 *) Numerous improvements to the Win32 build system. Introduced command line
3291 builds without requiring .mak files for MSVC 6.0 and later versions.
3292 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
3295 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
3296 reporting of uninstalled services and other error conditions, and changed the
3297 default service name to Apache2. [William Rowe]
3299 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
3300 compatibility with existing Apache 1.3 Win32 Apache management utilites.
3301 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
3303 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
3304 [William Rowe, Greg Ames]
3306 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
3307 and RemoveCharset directives. [William Rowe]
3309 *) The Unix MPMs other than perchild now allow child server
3310 processes to use the accept mutex when starting as root and
3311 using SysV sems for the accept mutex. Previously, this
3312 combination would lead to fatal errors in the child server
3313 processes. perchild can't use SysV sems because of security
3314 issues. [Jeff Trawick, Greg Ames]
3316 *) Added Win32 revision stamp resources to all http binaries
3317 (including modules/ and support/ tools.) PR7322 [William Rowe]
3319 *) Fix ap_rvprintf to support more than 4K of data at one time.
3320 [Cody Sherr <csherr@covalent.net>]
3322 *) We have always used the obsolete/deprecated Netscape syntax
3323 for our tracking cookies; now the CookieStyle directive
3324 allows the Webmaster to choose the Netscape, RFC2109, or
3325 RFC2965 format. The new CookieDomain directive allows the
3326 setting of the cookie's Domain= attribute, too. PR #s 5006,
3327 5023, 5920, 6140 [Ken Coar]
3329 *) Tweak server/Makefile so that the rules for generating exports.c
3330 are compatible with make utilities which don't expand wildcards
3331 in a dependency list (e.g., OS/390 make, certain levels of GNU
3332 make). [Jeff Trawick]
3334 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
3336 *) Begin to sanitize the MPM configuration directives. Now, all
3337 MPMs use the same functions for all common MPM directives. This
3338 should make it easier to catch all bugs in these directives once.
3339 [Cody Sherr <csherr@covalent.net>]
3341 *) Close a major resource leak. Every time we had issued a
3342 graceful restart, we leaked a socket descriptor.
3345 *) Fix a problem with the new method code. We need to cast
3346 the 1 to an apr_int64_t or it will be treated as a 32-bit
3347 integer, and it will wrap after being shifted 32 times.
3348 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
3350 *) Fix a bug in mod_expires. Previous to this patch, if you
3351 told mod_expires to add 604800 seconds to the last-modified
3352 time, it actually added 604800 usec's to the last-modified time,
3353 so that when looking at the response it looked like nothing
3354 had been done. The root of the problem was that we always compute
3355 time in usec's, but we ask users to input sec's. This means we
3356 need to convert to usec's before using those values.
3359 *) The worker MPM now handles shutdown and restart requests. It
3360 definitely isn't perfect, but we do stop the servers correctly.
3361 The biggest problem right now is that SIGHUP causes the server to
3362 just die. [Ryan Bloom]
3364 Changes with Apache 2.0.23
3366 *) Use the prefork MPM by default on Unix. [various]
3368 *) Added a systray icon monitor application for Win32.
3369 [Mladen Turk <mturk@mappingsoft.com>]
3371 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3372 messages written to the rewrite log.
3373 [Richard Labennett <rlabenn@us.ibm.com>]
3375 *) All mod_autoindex query parsing is now quietly quashed with the
3376 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3377 still drops the column sort <a href>'s for the column headers, but
3378 IgnoreClient is required to ignore these Query options entirely.
3381 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3382 to allow the client to select plain, FancyIndexing or HTMLTable
3383 formatting, V=[0|1] to inhibit or enable version sorting, and
3384 P=pattern to return only specific files. The old Query Arguments
3385 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3386 as before), and O=A|D for ordering ascending or descending.
3389 *) Fixed an error in mod_include's directive parsing routines which
3390 caused #if, #elif, and #else expressions containing backslashes
3391 to be improperly evaluated. [Cliff Woolley]
3393 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3394 drop the icon column, SuppressRules to drop the <hr> elements,
3395 and HTMLTable to create rudimentary HTML table listings (implies
3396 FancyIndexing). [William Rowe]
3398 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3399 from Apache 1.3.15. This is needed for two reasons, first, given
3400 multiple machines within a server farm, ETags and Last-Modified
3401 stamps won't correspond from machine to machine, and second, many
3402 Unixes don't capture changes to the date or time stamp of existing
3403 files, since these don't modify the dirent itself. [William Rowe]
3405 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3406 and DirectoryWidth options from Apache 1.3.10.
3407 [William Rowe, Ken Coar]
3409 *) Eliminated FancyIndexing directive, deprecated early in Apache
3410 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3412 *) mod_autoindex now excludes any file names that would result in
3413 an error, other than a success or redirect. Also optimized
3414 the parent directory, always included except in the URI '/'.
3417 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3418 negotiated index pages, and prevent the server from defaulting
3419 to an autoindex of the directory. mod_negotiation will now die
3420 with a 500 Internal Error if it could match some filenames
3421 (e.g. for mod_dir) but none can be served. mod_negotation now
3422 refuses to serve any file with an extention that mod_mime doesn't
3423 recognize, and wasn't part of the request. [William Rowe]
3425 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3426 extension. This is already handled by multiviews, if the admin
3427 wishes to AddHandler .exe or define a content type handler and
3428 associate .exe files with that content type. Multiviews must be
3429 enabled to allow these to be served. [William Rowe]
3431 *) Speed up the server's response to a spike in incoming workload
3432 or restarts by assigning empty scoreboard slots to new processes
3433 when they are available. [Greg Ames]
3435 *) Add a handler to mod_includes.c. This handler is designed to
3436 implement the XbitHack directive. This can't be done with a
3437 fixup, because we need to check the content-type, which is
3438 only available in the handler phase. [Ryan Bloom]
3440 *) Make the includes filter check return codes from filters lower in
3441 the filter chain. If a lower level filter returns an error, then
3442 the request needs to stop immediately. This allows mod_include to
3443 stop parsing data once a lower filter recognizes an error.
3446 *) Add the ability to extend the methods that Apache understands
3447 and have those methods <limit>able in the httpd.conf. It uses
3448 the same bit mask/shifted offset as the original HTTP methods
3449 such as M_GET or M_POST, but expands the total bits from an int to
3450 an ap_int64_t to handle more bits for new request methods than
3451 an int provides. [Cody Sherr <csherr@covalent.net>]
3453 *) Fix broken mod_mime behavior in merging its arguments. Possible
3454 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
3456 *) Solve many mod_ssl porting issues (too many to detail) with
3457 help from the whole team, but most notably [Ralf S. Engelschall,
3458 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
3459 Doug MacEachern, William Rowe, Cliff Woolley]
3461 *) More stall fixes for the threaded & worker mpm's.
3462 Make mod_status output more accurate. Don't
3463 count workers in processes which aren't actively
3464 serving requests. [Greg Ames]
3466 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
3468 *) Add a single listener/multiple worker MPM. This MPM is
3469 definately not fully correct, but it allows us to solve many
3470 of the problems that exist in the threaded MPM. This is a
3471 modified version of the threaded MPM. [Ryan Bloom]
3473 *) Improve content generation throughout Apache, providing closer
3474 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
3475 Transitional specifications. [William Rowe]
3477 Changes with Apache 2.0.22
3479 *) Fix a problem where the threaded MPM stalls after restarts or
3480 segfaults. Also prevent multiple active processes from using
3481 the same scoreboard slot. [Greg Ames]
3483 *) Apache/Win32 now fills in the service description with Apache's
3484 server version string, including loaded and advertised modules.
3487 *) Improved support for the Win32 build, to recover gracefully from
3488 missing apr or apr-util directories or the awk interpreter,
3489 create the proper cgi-bin examples, including a test-cgi.bat, and
3490 fix the perl shebang line for printenv.pl, when installing from
3491 the build environment. [William Rowe]
3493 *) Fix a segfault in threaded.c caused by passing uninitialized
3494 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
3496 *) Use new APR number conversion functions to reduce CPU consumption
3497 when setting the content length, and in mod_log_config.
3500 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
3501 where HEAD response headers were being repeated twice for
3502 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
3503 problem in the http_header filter was exposed by the recent rewrite
3504 of the content_length filter. [Taketo Kabe, Bill Stoddard]
3506 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
3507 restarts. A garbage pointer to a vhost's server_rec from the
3508 previous generation was being left around under certain
3509 conditions. [Greg Ames]
3511 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
3512 used to appear as '(none', without the closing paren.
3513 [Günter Knauf <eflash@gmx.net>]
3515 *) Improve the exports generating awk script. In the past, we had
3516 work around problems in the awk script by avoiding some #if and
3517 #ifdefs. This has bitten us many times in generating the exports.c
3518 file. This improvement allows corrects the header file parsing.
3519 [Sander Striker <striker@apache.org>]
3521 Changes with Apache 2.0.21
3523 *) Resolve the Win32 htpasswd bug, where a file that existed would be
3524 overwritten, regardless of the -c flag.
3525 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
3527 *) Introduce connection sub-pools into ab. Truncating the lifetime
3528 of these allocations means that ab no longer perpetually grows
3529 its working set, running out of memory on large request attempts.
3532 *) Make scoreboard creation a hook. This allows management
3533 modules to have access to the scoreboard at the time that it is
3534 created, and at every restart request.
3535 [Cody Sherr <csherr@covalent.net>]
3537 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
3538 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
3539 daemon index actually used in the scoreboard. I also
3540 updated the pertinent calls. [Paul J. Reder]
3542 *) Win32: Prevent listening sockets from being inherited by
3543 the Apache child process, CGI scripts, rotatelog process
3544 etc. If the Apache child process segfaults, any processes
3545 that the child started are not reaped. Prior to this fix,
3546 these processes inherited the listening sockets which sometimes
3547 prevented the restarted Apache child process from accepting
3548 connections (ie, the server would hang).
3551 *) Provide vhost and request strings when ExtendedStatus is on.
3554 *) Fix some issues with the pod and prefork: check the pod *after*
3555 processing a connection so that a server processing a time-
3556 consuming request bails out as soon as practical; when the
3557 parent process wakes up a server process via connect(), use an
3558 APR timeout on the connect() so that we don't hang for a long
3559 time if there aren't server processes around to do accept().
3560 [Jeff Trawick, Greg Ames]
3562 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
3563 spends a lot of time in apr_table_get calls. Using the default
3564 httpd.conf, the tables for languages and charsets are somewhat
3565 large, so the time spent scanning them on each request is
3566 significant. Replacing the tables with hash tables provides
3567 a nice speedup. [Brian Pane <bpane@pacbell.net>]
3569 *) Add two functions to allow modules to access random parts of the
3570 scoreboard. This allows modules compiled for one MPM to access the
3571 scoreboard, even if it the server was compiled for another MPM.
3572 [Harrie Hazewinkel <harrie@covalent.net>]
3574 Changes with Apache 2.0.20
3576 *) Fix problem in content-length filter where the filter would
3577 buffer all the output from a CGI before sending any bytes
3578 down the filter stack to the network. This problem would cause
3579 significant memory consumption if the CGIs generated
3580 lots of bytes. [Bill Stoddard]
3582 *) Get non-blocking CGI pipe reads working with the bucket brigades.
3585 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
3588 *) Fix a bug in the threaded MPM that would cause it to kill off all
3589 workers immediately after starting if the number of workers started
3590 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
3592 Changes with Apache 2.0.19
3594 *) Fix problem with threaded MPM. The problem was that if each child
3595 process was busy serving a single long-lived request and the server
3596 was sent a graceful restart signal, the server would stop serving
3597 requests. This would happen because each child process would wait to
3598 die until the last thread was done, and the parent wouldn't spawn any
3599 new children until a process died. Now, the parent looks at the fact
3600 that the children are dying gracefully, and starts new children.
3601 Those new children only start enough threads to compliment the number
3602 of threads in the other child process that shares the same spot in
3603 the scoreboard. In this way, we make sure to never go over
3604 MaxClients. [Ryan Bloom]
3606 *) modified mod_negotiation and mod_autoindex to speed up by almost a
3607 factor of two on apr_dir_read()-enhanced platforms, such as Win32
3608 and OS2, by calling ap_sub_request_lookup_dirent() with the results
3609 already provided by apr_dir_read(). [William Rowe]
3611 *) mod_file_cache is now more robust to filtering and serves requests
3612 slightly more efficiently. [Cliff Woolley]
3614 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
3615 Module was calling ap_rwrite() followed by ap_rflush() but the
3616 served content was not being displayed in the browser. Inspection
3617 of the output stream revealed that the first data chunk was
3618 missing the trailing CRLF required by the RFC. [Bill Stoddard]
3620 *) apxs no longer generates ap_send_http_header() in the example handler
3622 *) Fix an ab problem which could cause a divide-by-zero exception
3623 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
3624 [Ian Holsman <ianh@cnet.com>]
3626 *) Solve case-insensitive platforms' confusion about negotiated
3627 filenames, allowing files of differnt case to match in choosing
3628 the document to serve. [William Rowe]
3630 *) Fix brokenness when ThreadsPerChild is higher than the built-in
3631 limit. We left ap_threads_per_child at the higher value which
3632 led to segfaults when doing certain scoreboard operations.
3635 *) Fix seg faults and/or missing output from mod_include. The
3636 default_handler was using the subrequest pool for files and
3637 MMAPs, even though the associated APR structures typically
3638 live longer than the subrequest. [Greg Ames]
3640 *) Extend mod_setenvif to support specifying regular expressions
3641 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
3642 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
3643 will cause HAVE_TS to be set if any of the request headers begins
3644 with "TS" and has a value that begins with any character in the
3645 set [a-z]. [Bill Stoddard]
3647 *) httpd children now re-bind themselves to a random CPU on
3648 multiprocessor systems on AIX via bindprocessor() in 2.0.
3649 [Victor J. Orlikowski]
3651 *) Fix htdigest. It would go into a loop in getline when adding
3652 a second user. [Bill Stoddard]
3654 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
3656 *) Automatically generate httpd.exp for AIX.
3657 DSOs now work again on AIX in 2.0
3658 [Victor J. Orlikowski]
3660 *) Add a new request hook, error_log. This phase allows modules
3661 to act on the error log string _after_ it has been written
3662 to the error log. The goal for this hook is to allow monitoring
3663 modules to send the error string to the monitoring agent.
3666 *) Modify mod_echo to make it use filters for input and output.
3667 [Ryan Morgan <rmorgan@covalent.net>]
3669 *) Extend mod_headers to support conditional driven Header
3670 add, append and set. Use SetEnvIf to set an envar and conditionally
3671 add/append/set headers based on this envar thusly:
3673 SetEnvIf TSMyHeader value HAVE_TSMyHeader
3674 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
3676 If the request contains header "TSMyHeader: value" then header
3677 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
3680 *) Extend mod_headers to support using format specifiers on Header
3681 add, append and set header values. Two format specifiers are supported:
3683 %t - reports, in UTC microseconds since the epoch, when the
3684 request was received.
3686 %D - reports the time, in microseconds, between when the request was
3687 received and the response sent.
3690 Header add MyHeader "This request served in %D microseconds. %t"
3692 results in a header being added to the response that looks like this:
3694 MyHeader: This request served in D=5438 microseconds. t=991424704447256
3698 *) Fix reset_filter(). We need to be careful how we remove filters.
3699 If we set r->output_filters to NULL, we also have to reset the
3700 connection's filters. [John Sterling]
3702 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
3704 *) Add a check to ap_die() to make sure the filter stack is sane and
3705 contains the correct basic filters when an error occurs. This fixes
3706 a problem where headers are not being sent on error. [John Sterling]
3708 *) New Header directive 'echo' option. "Header echo regex" will
3709 cause any headers received on the request that match regex to be
3710 echoed to (included in) the response headers.
3713 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
3714 This prevented the inclusion of apr_compat.h. PR #7773
3715 [Oleg Broytmann <phd@phd.pp.ru>]
3717 *) Moved util_uri to the apr-util library. This required a bunch of
3718 apr_name changes for the uri utility functions. [Justin Erenkrantz]
3720 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
3721 insert_filter phase so that other filters are not bypassed by default.
3724 *) Reimplement mod_headers as an output filter. mod_headers can now
3725 add custom headers to inbound requests using the RequestHeader directive
3726 and to responses using the same old Header directive. [Graham Leggett]
3728 Changes with Apache 2.0.18
3730 *) Fix command-line processing so that if a bad argument is specified
3731 Apache will exit. [Jeff Trawick]
3733 *) Change the make targets and rules to be consistent in all of the
3734 Apache-owned source trees. [Roy Fielding]
3736 *) Fix processing of the TRACE method. Previously we passed bogus
3737 parms to form_header_field() and it overlaid some vhost structures,
3738 resulting in a segfault in check_hostalias().
3739 [Greg Ames, Jeff Trawick]
3741 *) Win32: Add support for reliable piped logs. If the logging process
3742 goes down, Apache will automatically restart it. This function has
3743 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
3746 *) Do not start piped log processes during the config file
3747 preflight. This change also circumvents a problem on
3748 Windows where the rotatelog processes created during preflight
3749 was not getting cleaned up properly.
3752 *) add "Request Phase Participation" info to mod_info
3755 *) Make first phase changes to the scoreboard data structures in
3756 preparation for the rewriting of the scoreboard per my posted
3757 design notes. [Paul J. Reder]
3759 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
3760 and apr-util, allow it to be overridden by the configure command-line
3761 (default="--silent") and introduce LT_LDFLAGS to replace what we were
3762 formerly abusing as LTFLAGS. [Roy Fielding]
3764 *) Clean up the reporting of incorrect closing container tags.
3765 [Barrie Slaymaker <barries@slaysys.com>]
3767 *) Simplify the configure process by moving all libtool stuff to APR
3768 and moving hints.m4 inline. [Roy Fielding]
3770 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
3771 of functions used by mod_proxy for export in the DLL
3772 [Ian Holsman <IanH@cnet.com>]
3774 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
3775 request body from its stdin but no reqest body is being written to
3776 the cgi. [Jeff Trawick]
3778 *) mod_log_config: %c connection status incorrectly logged
3779 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
3782 *) Get mod_cern_meta working under Windows
3785 *) Create Files, and thus MMAPs, out of the request pool, not the
3786 connection pool. This solves a small resource leak that had us
3787 not closing files until a connection was closed. In order to do
3788 this, at the end of the core_output_filter, we loop through the
3789 brigade and convert any data we have into a single HEAP bucket
3790 that we know will survive clearing the request_rec.
3791 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
3794 *) Completely revamp configure so that it preserves the standard make
3795 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
3796 the configure additions to EXTRA_* variables. Also, allow the user
3797 to specify NOTEST_* values for all of the above, which eliminates the
3798 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
3799 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
3800 avoid pointless duplications. Fix the order in which flags are given
3801 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
3802 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
3803 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
3804 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
3806 *) Get mod_tls to compile/work better on Windows. PR #7612
3807 [Bernhard Schrenk <b.schrenk@improx.com>]
3809 *) Fix shutdown/restart hangs in the threaded MPM.
3810 [Jeff Trawick, Greg Ames, Ryan Bloom]
3812 *) Removed the keptalive boolean from conn_rec because it is now only
3813 used by a single routine and can be replaced by a local variable.
3814 [Greg Stein, Ryan Bloom, Roy Fielding]
3816 *) Patch prefork to put enough of the signal processing back in so that
3817 signals are all handled properly now. The previous patch fixed the
3818 deadlock race condition, but broke the user directed signal handling.
3819 This fixes it to work the way it did before my previous prefork patch
3820 (primarily, SIGTERM is now working).
3822 *) Change how input filters decide how much data is returned to the
3823 higher filter. We used to use a field in the conn_rec, with this
3824 change, we use an argument to ap_get_brigade to determine how much
3825 data is retrieved. [Ryan Bloom]
3827 *) Fix seg fault at start-up introduced by Ryan's change to enable
3828 modules to specify their own logging tags. mod_log_config
3829 registers an optional function, ap_register_log_handler().
3830 ap_register_log_handler() was being called by http_core before
3831 the directive hash table was created. This patch creates the
3832 directive hash table before ap_register_log_handler() is
3833 registered as an optional function.
3834 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
3836 *) Add ap_set_int_slot() function
3837 [John K. Sterling <sterling@covalent.net>]
3839 *) Under certain circumstances, Apache did not supply the
3840 right response headers when requiring authentication.
3841 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
3842 (This is a port of the change that went into Apache 1.3.19.)
3844 *) Allow modules to specify their own logging tags. This basically
3845 allows a module to tell mod_log_config that when %x is encountered
3846 a specific function should be called. Currently, x can be any single
3847 character. It may be more useful to make this a string at some point.
3850 Changes with Apache 2.0.17
3852 *) If a higher-level filter handles the the byterange aspects of a
3853 request, then the byterange filter should not try to redo the
3854 work. The most common case of this happening, is a byterange
3855 request going through the proxy, and the origin server handles
3856 the byterange request. The proxy should ignore it.
3857 [Graham Leggett <minfrin@sharp.fm>]
3859 *) Changed the threaded mpm to have child_main join to each of the
3860 worker threads to make sure the kids are all gone before child_main
3861 exits after a signal (cleanup from perform_idle_server_maintenance).
3862 This is an extension of Ryans recent commit to make the child_main
3865 *) Add more options to the ap_mpm_query function. This also allows MPMs to
3866 report if their threads are dynamic or static. Finally, this also
3867 implements a new API, ap_show_mpm, which returns the MPM that was
3868 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
3870 *) Do not install the binaries from the support directory twice.
3871 [jun-ichiro hagino <itojun@iijlab.net>]
3873 *) The ap_f* functions should flush data to the filter that is passed
3874 in, not the the filter after the one passed in.
3875 [Ryan Morgan <rmorgan@covalent.net>]
3877 *) Make ab work again by changing its native types to apr types and formats.
3878 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3880 *) Move the byterange filter and all of the supporting functions back
3881 to the HTTP module. The byterange filter turned out to be very
3882 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
3884 *) Make clean, distclean, and extraclean consistently according to the
3885 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3887 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
3888 This may have been causing problems stopping processes in the threaded
3891 *) Fix content-length in mod_negotiation to a long int representation.
3894 *) Remove BindAddress from the default config file.
3895 [giles@nemeton.com.au]
3897 *) Allow module authors to add a module to their Apache build using
3898 --with-module, without re-running buildconf. The syntax is:
3899 --with-module=module_type:/path/to/module.c
3900 The configure script will copy the module.c file to
3901 modules/module_type, and it will be added to the relevant Makefiles.
3902 currently, this only works for static modules. [Ryan Bloom]
3904 *) Changes required to make prefork clean up idle children properly.
3905 There was a window during which a starting worker deadlocks when
3906 an idle cleanup arrives before it completes init. Apache then keeps
3907 trying to cleanup the same deadlocked worker forever (until higher
3908 pids come along, but it still will never reduce below the deadlocked
3909 pid). Thus the number of children would not reduce to the correct
3910 idle level. [Paul J. Reder]
3912 Changes with Apache 2.0.16
3914 *) Change the default installation directory to /usr/local/apache2,
3915 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
3917 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
3920 *) Get MaxRequestsPerChild working with the Windows MPM.
3923 *) Make generic hooks to work, with mod_generic_hook_import/export
3924 experimental modules. [Ben Laurie, Will Rowe]
3926 *) Fix segfaults for configuration file syntax errors such as
3927 "<Directory>" followed by "</Directory" and
3928 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
3930 *) Cleanup the --enable-layout option of configure. This makes
3931 us use a consistent location for the config.layout file, and it
3932 makes configure more portable.
3933 [jun-ichiro hagino <itojun@iijlab.net>]
3935 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
3936 csv/gnuplot format, rudimentary ssl support and various other tweaks
3937 to make results more true to what is measured. The upshot of this it
3938 turns out that 'ab' has often underreported the true performance of
3939 apache. Often by a order of magnitude :-) See talk/paper of Sander
3940 Temme at April ApacheCon 2001 for details.
3941 [Dirk-Willem van Gulik]
3943 *) Clean up mod_cgid's temporary request pool. Besides fixing a
3944 storage leak this ensures that some unnecessary pipes are closed.
3947 *) Performance: Add quick_handler hook. This hook is called at the
3948 very beginning of the request processing before location_walk,
3949 translate_name, etc. This hook is useful for URI keyed content
3950 caches like Mike Abbott's Quick Shortcut Cache.
3953 *) top_module global variable renamed to ap_top_module [Perl]
3955 *) Move ap_set_last_modified to the core. This is a potentially
3956 controversial change, because this is kind of HTTP specific. However
3957 many protocols should be able to take advantage of this kind of
3958 information. I expect that headers will need one more layer of
3959 indirection for multi-protocol work, but this is a small step in
3960 the right direction. [Ryan Bloom]
3962 *) Enable mod_status by default. This matches what Apache 1.3 does.
3965 *) Add a ScriptSock directive to the default config file. This is
3966 only enabled when mod_cgid is used.
3967 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3969 Changes with Apache 2.0.15
3971 *) Untangled the buildconf script and eliminated the need for build's
3972 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
3973 libtool muck that is now under srclib/apr/build. [Roy Fielding]
3975 *) Win32: Don't accept more connections than we have worker threads
3979 *) Fix bug in the Unix threaded.c MPM that allowed child processes
3980 to fork() new child processes.
3983 *) SECURITY: Fix a major security problem with double-reverse lookup
3984 checking. Previously, a client connecting over IPv4 would not be
3985 matched properly when the server had an IPv6 listening socket.
3986 PR #7407 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
3988 *) Change the way the beos MPM handles polling to allow it to stop and
3989 restart. Problem was the sockets being polled were being reset by
3990 the select call, so once it had accepted a connection it was no
3991 longer listening on the UDP socket we use for shutdown instructions.
3992 APR needs to be altered, patch on it's way. [David Reid]
3994 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
3995 on error exit from ap_getline(). Some other code got upset because
3996 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
3998 *) Handle ap_discard_request_body() being called more than once.
3999 [Greg Ames, Jeff Trawick]
4001 *) Get rid of an inadvertent close of file descriptor 2 in
4002 mod_mime_magic. [Greg Ames, Jeff Trawick]
4004 *) Add a hook, create_request. This hook allows modules to modify
4005 a request while it is being created. This hook is called for all
4006 request_rec's, main request, sub request, and internal redirect.
4007 When this hook is called, the the r->main, r->prev, r->next
4008 pointers have been set, so modules can determine what kind of
4009 request this is. [Ryan Bloom]
4011 *) Cleanup the build process a bit more. The Apache configure
4012 script no longer creates its own helper scripts, it just
4014 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
4016 *) Stop the forced downgrade of the connection to HTTP/1.0 for
4017 proxy requests. [Graham Leggett]
4019 *) Avoid using sscanf to determine the HTTP protocol number in
4020 the common case because sscanf is a performance hog. From
4021 Mike Abbot's Accelerating Apache patch number 6.
4022 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
4024 *) SECURITY: Fix a security exposure in mod_access. Previously when
4025 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
4026 were not evaluated properly (PR #7407). Also, add the ability to
4027 specify IPv6 address strings with optional prefix length on Allow
4028 and Deny. [Jeff Trawick]
4030 *) Enhance rotatelogs so that a UTC offset can be specified, and
4031 the logfile name can be formatted using strftime(3). (Brought
4032 forward from 1.3.) [Ken Coar]
4034 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
4035 DuplicateHandle on an IOCompletionPort (a practice which
4036 MS "discourages"). The new model does not rely on associating
4037 the completion port with the listening sockets, thus the
4038 completion port can be completely managed within the child
4039 process. A dedicated thread accepts connections off the network,
4040 then calls PostQueuedCompletionStatus() to wake up worker
4041 threads blocked on the completion port.
4044 *) Bring forward the --suexec-umask option which allows the
4045 builder to preset the umask for suexec processes. [Ken Coar]
4047 *) Add a -V flag to suexec, which causes it to display the
4048 compile-time settings with which it was built. (Only
4049 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
4051 *) Mod_include should always unset the content-length if the file is
4052 going to be passed through send_parsed_content. There is no to
4053 determine if the content will change before actually scanning the
4054 entire content. It is far safer to just remove the C-L as long
4055 as we are scanning it. [Ryan Bloom]
4057 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
4058 request and not Proxy-Authenticate.
4059 [Graham Leggett <minfrin@sharp.fm>]
4061 Changes with Apache 2.0.14
4063 *) Fix content-length computation. We ONLY compute a content-length if
4064 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
4065 or we already have all the data. [Ryan Bloom]
4067 *) Report unbounded containers in the config file. Previously, a typo
4068 in the </container> directive could result in the rest of the config
4069 file being silently ignored, with undesired defaults used.
4072 *) Make the old_write filter use the ap_f* functions for the buffering.
4075 *) Move more code from the http module into the core server. This
4076 is core code, basically the default handler, the default input
4077 and output filters, and all of the core configuration directives.
4078 All of this code is required in order for the server to work, with or
4079 without HTTP. The server is closer to working without the HTTP
4080 module, although there is still more to do. [Ryan Bloom]
4082 *) Fix a number of SGI compile warnings throughout the server. Fix some
4083 bad parameters to apr_bucket_read(). Fix a bad statement in
4084 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
4085 consistently; we were mixing apr_time_t and time_t in invalid ways
4086 before. In load_file(), call apr_dso_error() instead of
4087 apr_strerror() so that we get a more specific string on some platforms.
4088 PR #6980 [Jeff Trawick]
4090 *) Allow modules to query the MPM about it's execution profile. This
4091 query API can and should be extended in the future, but for now,
4092 max_daemons, and threading or forking is a very good start.
4093 [Jon Travis <jtravis@covalent.net>]
4095 *) Modify mod_include to send blocks of data no larger than 9k.
4096 Without this, mod_include will wait until the whole file is parsed,
4097 or the first tag is found to send any data to the client.
4098 [Paul J. Reder <rederpj@raleigh.ibm.com>]
4100 *) Fix mod_info, so that <Directory> and <Location> directives are
4101 not displayed twice when displaying the current configuration.
4102 [Ryan Morgan <rmorgan@covalent.net>]
4104 *) Add config directives to override DEFAULT_ERROR_MSG and
4105 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
4106 [Dan Rench <drench@xnet.com>]
4108 *) Get mod_info building and loading on Win32. [William Rowe]
4110 *) Begin to move protocol independant functions out of mod_http. The goal
4111 is to have only functions that are HTTP specific in the http directory.
4114 Changes with Apache 2.0.13
4116 *) Don't assume that there will always be multiple calls to the byterange
4117 filter. It is possible that we will need to do byteranges with only
4118 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
4120 *) Move the error_bucket definition from the http module to the
4121 core server. Every protocol will need this ability, not just
4124 Changes with Apache 2.0.12
4126 *) Modify mod_file_cache to save pre-formatted strings for
4127 content-length and last-modified headers for performance.
4128 [Mike Abbot <mja@trudge.engr.sgi.com>]
4130 *) Namespace protect IOBUFSIZ since it is exposed in the API.
4131 [Jon Travis <jtravis@covalent.net>]
4133 *) Use "Basic" authentication instead of "basic" in ab, as the spec
4134 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
4136 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
4137 without ever filling it out. This fixes PR 7271.
4138 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
4139 Cliff Woolley <cliffwoolley@yahoo.com>]
4141 *) Add a couple of GCC attribute tags to printf style functions.
4142 [Jon Travis <jtravis@covalent.net>]
4144 *) Add the correct language tag for interoperation with the Taiwanese
4145 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
4147 *) Migrate the perchild MPM to use the new apr signal child, and
4148 APR thread functions. [Ryan Bloom]
4150 *) Close one copy of the CGI's stdout before creating the new process.
4151 The CGI will still have stdout, because we have already dup'ed it.
4152 This keeps Apache from waiting forever to send the results of a CGI
4153 process that has forked a long-lived child process.
4154 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
4156 *) Remove the rest of the pthreads functions from the threaded MPM.
4157 This requires the APR support for a signal thread that was just
4160 *) Make mod_dir use a fixup for sending a redirect to the browser.
4161 Before this, we were using a handler, which doesn't make much
4162 sense, because the handler wasn't generating any data, it would
4163 either return a redirect error code, or DECLINED. This fits the
4164 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
4166 *) Make the threaded MPM use APR threads instead of pthreads.
4169 *) Get mod_tls to the point where it actually appears to work in all cases.
4172 *) implement --enable-modules and --enable-mods-shared for "all" and
4173 "most". [Greg Stein]
4175 *) Move the threaded MPM to use APR locks instead of pthread locks.
4178 *) Rename mpmt_pthread to threaded. This is more in line with the
4179 fact that mpmt_pthread shouldn't be using pthreads directly, and
4180 it is a smaller name that doesn't tie into anything.
4183 *) Rename the module structures so that the exported symbol matches
4184 the file name, and it is easier to automate the installation
4185 process (generating LoadModule directives from the module filenames).
4188 *) Remove the coalesce filter. With the ap_f* functions, this filter
4189 is no longer needed. [Ryan Bloom]
4191 Changes with Apache 2.0.11
4193 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
4194 added feature of allowing a uid/gid per child process. If no
4195 uid/gid is specified, then Perchild behaves exactly like dexter.
4198 *) Get perchild building again. [Ryan Bloom]
4200 *) Don't disable threads just because we are using the prefork MPM.
4201 If somebody wants to compile without threads, they must now add
4202 --disable-threads to the configure command line. [Ryan Bloom]
4204 *) Begin to move the calls to update_child_status into common code, so
4205 that each individual MPM does not need to update the scoreboard itself.
4208 *) Allow mod_tls to compile under Unix boxes where openssl has been
4209 installed to the system include files.
4210 [Gomez Henri <new-httpd@slib.fr>]
4212 *) Cleanup the mod_tls configure process. This should remove any need
4213 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
4214 configure doesn't check that yet. [Ryan Bloom]
4216 *) Add a very early prototype of SSL support (in mod_tls.c). It is
4217 vital that you read modules/tls/README before attempting to build
4220 *) Fix a potential seg fault on all platforms. David Reid fixed this
4221 on BEOS, but the problem could happen anywhere, so we don't want
4222 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
4224 *) Add new LogFormat directive, %D, to log time it takes to serve a
4225 request in microseconds. [Bill Stoddard]
4227 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
4228 SetOutputFilter. This corresponds nicely with the other Set
4229 directives, which operate on containers while the Add* directives
4230 tend to work directly on extensions. [Ryan Bloom]
4232 *) Cleanup the header handling a bit. This uses the apr_brigade_*
4233 functions for the buffering so that we don't need to compute
4234 the length of the headers before we actually create the header
4235 buffer. [Ryan Bloom]
4237 *) Allow filters to buffer data using the ap_f* functions. These have
4238 become macros that resolve directly to apr_brigade_*.
4241 *) Get the Unix MPM's to do a graceful restart again. If we are going
4242 to register a cleanup with ap_cleanup_scoreboard, then we have to
4243 kill the cleanup with the same function, and that function can't be
4244 static. [Ryan Bloom]
4246 *) Install all required header files. Without these, it was not
4247 possible to compile some modules outside of the server.
4250 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
4251 forward from 1.3 to 2.0, we missed a single line, which broke regex
4252 aliases. [Ryan Bloom]
4254 *) We have a poor abstraction in the protocol. This is a temporary
4255 hack to fix the bug, but it will need to be fixed for real. If
4256 we find an error while sending out a custom error response, we back
4257 up to the first non-OK request and send the data. Then, when we send
4258 the EOS from finalize_request_protocol, we go to the last request,
4259 to ensure that we aren't sending an EOS to a request that has already
4260 received one. Because the data is sent on a different request than
4261 the EOS, the error text never gets sent down the filter stack. This
4262 fixes the problem by finding the last request, and sending the data
4263 with that request. [Ryan Bloom]
4265 *) Make the server status page show the correct restart time, and
4266 thus the proper uptime. [Ryan Bloom]
4268 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
4269 should reduce the amount of duplicate code that is required to
4270 create CGI processes.
4271 [Paul J. Reder <rederpj@raleigh.ibm.com>]
4273 *) ap_new_connection() closes the socket and returns NULL if a socket
4274 call fails. Usually this is due to a connection which has been
4275 reset. [Jeff Trawick]
4277 *) Move the Apache version information out of httpd.h and into release.h.
4278 This is in preparation for the first tag with the new tag and release
4279 system. [Ryan Bloom]
4281 *) Begin restructuring scoreboard code to enable adding back in
4282 the ability to use IPC other than shared memory.
4283 Get mod_status working on Windows again. [Bill Stoddard]
4285 *) Make mod_status work with 2.0. This will work for prefork,
4286 mpmt_pthread, and dexter. [Ryan Bloom]
4288 *) Correct a typo in httpd.conf.
4289 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
4291 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
4293 *) Get the correct IP address if ServerName isn't set and we can't
4294 find a fully-qualified domain name at startup.
4295 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
4297 *) Make mod_cgid work with SuExec. [Ryan Bloom]
4299 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
4300 'extra' stat's for user/group since they should never occur, and now
4301 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
4302 volumes. [William Rowe]
4304 *) Adopt apr features to simplify mod_includes. This changes the
4305 behavior of the USER_NAME variable, unknown uid's are now reported
4306 as USER_NAME="<unknown>" rather than the old user#000 result.
4307 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
4309 *) Adopt apr features for simplifing mod_userdir, and accept the new
4310 Win32/OS2 exceptions without hiccuping. [William Rowe]
4312 *) Replace configure --with-optim option by using and saving the
4313 environment variable OPTIM instead. This is needed because configure
4314 options do not support multiple flags separated by spaces.
4317 *) Fix some byterange handling. If we get a byte range that looks like
4318 "-999999" where that is past the end of the file, we should return
4319 a PARTIAL CONTENT status code, and return the whole file as one big
4320 byterange. This matches the 1.3 handling now. [Ryan Bloom]
4322 *) Make the error bucket a real meta-data bucket. This means that the
4323 bucket length is 0, and a read returns NULL data. If one of these
4324 buckets is passed down after the headers are sent, this data will
4325 just be ignored. [Greg Stein]
4327 *) The prefork MPM wasn't killing child processes correctly if a restart
4328 signal was received while the process was serving a request. The child
4329 process would become the equivalent of a second parent process. If
4330 we break out of the accept loop, then we need to do die after cleaning
4331 up after ourselves. [Ryan Bloom]
4333 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
4334 restarts. [Ryan Bloom]
4336 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
4337 the most optimal APR_FINFO_wanted bits. This spares Win32 from
4338 performing very expensive owner, group and permission lookups
4339 and allows the server to function until these apr_finfo_t fields
4340 are implemented under Win32. [William Rowe]
4342 *) Support for typedsafe optional functions - that is functions exported by
4343 optional modules, which, therefore, may or may not be present, depending
4344 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
4345 for sample code. [Ben Laurie]
4347 *) filters can now report an HTTP error to the server. This is done
4348 by sending a brigade where the first bucket is an error_bucket.
4349 This bucket is a simple bucket that stores an HTTP error and
4350 a string. Currently the string is not used, but it may be needed
4351 to output an error log. The http_header_filter will find this
4352 bucket, and output the error text, and then return
4353 AP_FILTER_ERROR, which informs the server that the error web page
4354 has already been sent. [Ryan Bloom]
4356 *) If we get an error, then we should remove all filters except for
4357 those critical to serving a web page. This fixes a bug, where
4358 error pages were going through the byterange filter, even though
4359 that made no sense. [Ryan Bloom]
4361 *) Relax the syntax checking of Host: headers in order to support
4362 iDNS. PR#6635 [Tony Finch]
4364 *) Cleanup the byterange filter to use the apr_brigade_partition
4365 and apr_bucket_copy functions. This removes a lot of very messy
4366 code, and hopefully makes this filter more stable.
4369 *) Remove AddModule and ClearModuleList directives. Both of these
4370 directives were used to ensure that modules could be enabled
4371 in the correct order. That requirement is now gone, because
4372 we use hooks to ensure that modules are in the correct order.
4375 *) When SuExec is specified, we need to add it to the list of
4376 targets to be built. If we don't, then any changes to the
4377 configuration won't affect SuExec, unless 'make suexec' is
4378 specifically run. [Ryan Bloom]
4380 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4381 the APR_XTHREAD argument to open a file for consumption by
4382 parallel threads on win32. [William Rowe]
4384 *) Correct a bug in determining when we follow symlinks. The code
4385 expected a stat -1 result, not an apr_status_t positive error.
4386 Also check if the APR_FINFO_USER fields are valid before we
4387 follow the link. [William Rowe]
4389 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4390 mpm_common.c. These functions are only valid on some platforms,
4391 so they should not be in the main-line code. [Ryan Bloom]
4393 *) Remove ap_chdir_file(). This function is not thread-safe,
4394 and nobody is currently using it. [Ryan Bloom]
4396 *) Do not try to run make depend if there are no .c files in the
4397 current directory, doing so makes `make depend` fail.
4400 *) Update highperformance.conf to work with either prefork or
4401 pthreads mpms. [Greg Ames]
4403 *) Stop checking to see if this is a pipelined request if we know
4404 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4405 This keeps us from making an extra read call when serving a 1.0
4406 request. [Ryan Bloom and Greg Stein]
4408 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4409 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4410 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4412 *) Fix the RFC number mentioned when complaining about a missing
4413 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
4415 *) Fix an endless loop in ab which occurred when ab was posting
4416 and the server dropped the connection unexpectedly.
4419 *) Fix a segfault while handling request bodies in ap_http_filter().
4420 This problem has been seen with mod_dav usage as well as with
4421 requests where the body was just being discarded. [Jeff Trawick]
4423 *) Some adjustment on the handling and automatic setting (via
4424 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4425 add the capability to specify flags (NOTEST_CFLAGS and
4426 NOTEST_LDFLAGS) which are used to compile Apache, but
4427 not used during the configuration process. Useful for
4428 flags like "-Werror". [Jim Jagielski]
4430 *) Stop using environment variables to force debug mode or
4431 no detach. We now use the -D command line argument to
4432 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4433 [Greg Stein, Ryan Bloom]
4435 *) Change handlers to use hooks. [Ben Laurie]
4437 *) Stop returning copies of filenames from both apr_file_t and
4438 apr_dir_t. We pstrdup the filenames that we store in the
4439 actual structures, so we don't need to pstrdup the strings again.
4442 *) mod_cgi: Fix some problems where the wrong error value was being
4443 traced. [Jeff Trawick]
4445 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
4448 *) Add generic hooks. [Ben Laurie]
4450 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
4452 *) Fix a segfault caused by mod_ext_filter when the external filter
4453 program does not exist. [Jeff Trawick]
4455 *) Fix an output truncation error when on an HTTP >= 1.0 request an
4456 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
4457 was served through mod_charset_lite (or anything else that would
4458 create a transient bucket in this size range). ap_bucket_make_heap()
4459 silently failed (fixed), transient_setaside() discovered it, but
4460 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
4462 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
4463 is that some browsers send extra lines at the end of POST requests, and
4464 we don't want to delay sending data back to the user just because the
4465 browser isn't well behaved. [Ryan Bloom]
4467 *) Get SuEXEC working again. We can't send absolute paths to suExec
4468 because it refuses to execute those programs. SuEXEC also wasn't
4469 always recognizing configuration changes made using the autoconf
4472 *) Allow the buildconf process to find the config.m4 files in the correct
4473 order. Basically, we can now name config.m4 files as config\d\d.m4,
4474 and we will sort them correctly when inserting them into the build
4475 process. [Ryan Bloom]
4477 *) Get mod_cgid to use apr calls for creating the actual CGI process.
4478 This also allows mod_cgid to use ap_os_create_priviledged_process,
4479 thus allowing for SuExec execution from mod_cgid. Currently, we do
4480 not support everything that standard SuExec supports, but at least
4481 it works minimally now. [Ryan Bloom]
4483 *) Allow SuExec to be configured from the ./configure command line.
4486 *) Update some of the docs in README and INSTALL to reflect some of
4487 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
4489 *) If we get EAGAIN returned from the call to apr_sendfile, then we
4490 need to call sendfile again. This gets us serving large files
4491 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
4493 *) Get the support programs building cleanly again.
4494 [Cliff Woolley <cliffwoolley@yahoo.com>]
4496 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
4497 current directory logic now backs up over bin/ to determine the
4498 server root from the Apache.exe path.
4500 *) Apache/Win32 now follows the standard conventions of mod_foo.so
4501 loadable modules, dynamic libs are all named libfoo.dll, and the
4502 makefile.win populates the include, lib and libexec directories.
4504 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
4505 Apache gets IPv6 listening sockets by default. Additionally, the
4506 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
4507 numeric address strings (e.g., "Listen [fe80::1]:8080").
4510 *) Modify the install directory layout. Modules are now installed in
4511 modules/. Shared libraries should be installed in libraries/, but
4512 we don't have any of those on Unix yet. All install directories
4513 are modifyable at configure time. [Ryan Bloom]
4515 *) Install all header files in the same directory on Unix. [Ryan Bloom]
4517 *) Get the functions in server/linked into the server, regardless of
4518 which modules linked into the server. This uses the same hack
4519 for Apache that we use for APR and apr-util to ensure all of the
4520 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
4521 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
4522 the scripts a bit easier.
4525 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
4526 on the query, and remove IPv4 dependencies. [Jeff Trawick]
4528 *) Get all of the auth modules to the point that they will install and
4529 be loadable into the server. Our new build/install mechanism expects
4530 that all modules will have a common name format. The auth modules
4531 didn't use that format, so we didn't install them properly.
4534 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
4535 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
4537 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
4539 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
4540 after the end of the response. [Ryan Bloom]
4542 *) Get byterange requests working with responses that do not have a
4543 content-length. Because of the way byterange requests work, we have to
4544 have all of the data before we can actually do the byterange, so we
4545 can compute the content-length in the byterange filter.
4548 *) Get exe CGI's working again on Windows.
4551 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
4552 they keep track of whether or not their post config hook has been
4553 called before. Instead of a static variable (which is replaced when
4554 the DSO is loaded a second time), use userdata in the process pool.
4557 Changes with Apache 2.0a9
4559 *) Win32 now requires perl to complete the final install step for users
4560 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
4561 and installs the conf, htdocs and htdocs/manual directories.
4564 *) Make mod_include use a hash table to associate directive tags with
4565 functions. This allows modules to implement their own SSI tags easily.
4566 The idea is simple enough, a module can insert it's own tag and function
4567 combination into a hash table provided by mod_include. While mod_include
4568 parses an SSI file, when it encounters a tag in the file, it does a
4569 hash lookup to find the function that implements that tag, and passes
4570 all of the relevant data to the function. That function is then
4571 responsible for processing the tag and handing the remaining data back
4572 to mod_include for further processing.
4573 [Paul J. Reder <rederpj@raleigh.ibm.com>]
4575 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
4576 fewer parameters: the local and remote socket addresses were removed
4577 from the parameter list because all required information is available
4578 via the APR socket. [Jeff Trawick]
4580 *) Distribution directory structure reorganized to reflect a
4581 normal source distribution with external install targets.
4584 *) The MPMs that need multiple segments of shared memory now create
4585 two apr_shmem_t variables, one for each shared memory allocation.
4586 the problem is that we can't determine how much memory will be required
4587 for shared memory allocations once we try to allocate more than one
4588 variable. The MM code automatically aligns the shared memory allocations,
4589 so we end up needing to pad the amount of shared memory we want based
4590 on how many variables will be allocated out of the shared memory segment.
4591 It is just easier to create a second apr_shmem_t variable, and two
4592 shmem memory blocks.
4595 *) Cleanup the export list a bit. This creates a single unified list of
4596 functions exported by APR. The export list is generated at configure
4597 time, and that list is then used to generate the exports.c file.
4598 Because of the way the export list is generated, we only export those
4599 functions that are valid on the platform we are building on.
4602 *) Enable logging the cookie with mod_log_config
4603 [Sander van Zoest <sander@covalent.net>]
4605 *) Fix a segfault in mod_info when it reaches the end of the configuration.
4608 *) Added lib/aputil/ as a placeholder for utility functions which are not
4609 specific to the Apache HTTP Server (but do not make sense with APR).
4610 The first utility is "apu_dbm": a set of functions to work with DBM
4611 files. This first version can be compiled for SDBM or GDBM databases.
4614 *) Complete re-write of mod_include. This makes mod_include a filter that
4615 uses buckets directly. This has now served the FAQ correctly.
4616 [Paul Reder <rederpj@raleigh.ibm.com>]
4618 *) Allow modules to specify the first filter in a sub_request when
4619 making the sub_request. This keeps modules from having to change the
4620 output_filter immediately after creating the sub-request, and therefore
4621 skip the sub_req_output_filter. [Ryan Bloom]
4623 *) Update ab to accept URLs with IPv6 literal address strings (in the
4624 format described in RFC 2732), and to build Host header fields in
4625 the same format. This allows IPv6 literal address strings to be
4626 used with ab. This support has been tested against Apache 1.3 with
4627 the KAME patch, but Apache 2.0 does not yet work with this format
4628 of the Host header field. [Jeff Trawick]
4630 *) Accomodate an out-of-space condition in the piped logs and the
4631 rotatelogs.c code, and no longer churn log processes for this
4632 condition. [Victor J. Orlikowski]
4634 *) Add support for partial writes with apr_sendfile() to core_output_filter.
4637 Changes with Apache 2.0a8
4639 *) Add a directive to mod_mime so that filters can be associated with
4643 *) Get multi-views working again. We were setting the path_info
4644 field incorrectly if we couldn't find the specified file.
4647 *) Fix 304 processing. The core should never try to send the headers
4648 down the filter stack. Always, just setup the table in the request
4649 record, and let the header filter convert it to data that is ready
4653 *) More fixes for the proxy. There are still bugs in the proxy code,
4654 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
4658 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
4661 *) APR: Add new apr_getopt_long function to handle long options.
4662 [B. W. Fitzpatrick <fitz@red-bean.com>]
4664 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
4665 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
4666 hostname resolution/address string parsing and building
4667 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
4668 of one of the apr_sockaddr_t structures for a socket. Change
4669 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
4671 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
4672 I have proxied pages with it, cleanup will commence soon.
4675 *) Make the proxy work with filters. This isn't perfect, because we
4676 aren't dealing with the headers properly. [Ryan Bloom]
4678 *) Do not send a content-length iff the C-L is 0 and this is a head
4679 request. [Ryan Bloom]
4681 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
4682 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
4684 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
4686 *) Get the default_handler to stop trying to deal with HEAD requests.
4687 The idea is to let the content-length filter compute the C-L before
4688 we try to send the data. If we can get the C-L correctly, then we
4689 should send it in the HEAD response.
4692 *) The Header filter can now determine if a body should be sent based
4693 on r->header_only. The general idea of this is that if we delay
4694 deciding to send the body, then we might be able to compute the
4695 content-length correctly, which will help caching proxies to cache
4696 our data better. Any handler that doesn't want to try to compute
4697 the content-length can just send an EOS bucket without data and
4698 everything will just work.
4701 *) Add the referer to the error log if one is available.
4702 [Markus Gyger <mgyger@itr.ch>]
4704 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
4705 change, the root of the configuration tree has been exposed to modules
4707 [Ryan Morgan <rmorgan@covalent.net>]
4709 *) Get the core_output_filter to use the bucket interface directly.
4710 This keeps us from calling the content-length filter multiple times
4711 for a simple static request.
4714 *) We are sending the content-type correctly now.
4715 [Ryan Bloom and Will Rowe]
4717 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
4718 a bogus bytes-sent value when the only thing being sent was trailers
4719 and writev() returned an error (or EAGAIN). [Jeff Trawick]
4721 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
4722 hints file to determine which platforms define
4723 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
4726 *) APR: add apr_get_home_directory() [Jeff Trawick]
4728 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
4730 *) Not all platforms have INADDR_NONE defined by default. Apache
4731 used to make this check and define INADDR_NONE if appropriate,
4732 but APR needs the check too, and I suspect other applications will
4733 as well. APR now defines APR_INADDR_NONE, which is always a valid
4734 value on all platforms.
4735 [Branko Èibej <brane@xbc.nu>]
4737 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
4738 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
4740 *) Relax the syntax checking of Host: headers in order to support
4741 iDNS. PR#6635 [Tony Finch]
4743 *) When reading from file buckets we convert to an MMAP if it makes
4744 sense. This also simplifies the default handler because the
4745 default handler no longer needs to try to create MMAPs.
4748 *) BUFF has been removed from the main server. The BUFF code will remain
4749 in the code until it has been purged from the proxy module as well.
4752 *) Byteranges have been completely re-written to be a filter. This
4753 has been tested, and I believe it is working correctly, but it could
4754 doesn't work for the Adobe Acrobat plug-in. The output almost matches
4755 the output from 1.3, the only difference being that 1.3 includes
4756 a content-length in the response, and this does not.
4759 *) APR read/write functions and bucket read functions now operate
4760 on unsigned integers, instead of signed ones. It doesn't make
4761 any sense to use signed ints, because we return the error codes,
4762 so if we have an error we should report 0 bytes read or written.
4765 *) Always compute the content length, whether it is sent or not.
4766 The reason for this, is that it allows us to correctly report
4767 the bytes_sent when logging the request. This also simplifies
4768 content-length filter a bit, and fixes the actual byte-reporing
4769 code in mod_log_config.c
4772 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
4773 it says, because it was only used by EOS and FLUSH buckets. Since
4774 neither of those are required at the end of a brigade, this was
4775 really signifying FLUSH_THE_DATA, but that can be determined better
4776 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
4777 buckets now return a length of 0, which is actually the amount of data
4778 read, so they make more sense.
4781 *) Allow the core_output_filter to save some data past the end of a
4782 request. If we get an EOS bucket, we only send the data if it
4783 makes sense to send it. This allows us to pipeline request
4784 responses. As a part of this, we also need to allocate mmap
4785 buckets out of the connection pool, not the request pool. This
4786 allows the mmap to outlive the request.
4789 *) Make blocking and non-blocking bucket reads work correctly for
4790 sockets and pipes. These are the only bucket types that should
4791 have non-blocking reads, because the other bucket types should
4792 ALWAYS be able to return something immediately.
4795 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
4796 server, but use Ctrl+Break to initiate a graceful restart
4797 instead of duplicating behavior. [John Sterling]
4799 *) Patch mod_autoindex to set the Last-Modified header based on
4800 the directory's mtime, and add the ETag header. [William Rowe]
4802 *) Merge the 1.3 patch to add support for logging query string in
4803 such a way that "%m %U%q %H" is the same as "%r".
4806 *) Port three log methods from mod_log_config 1.3 to 2.0:
4807 CLF compliant '-' byte count, method and protocol.
4810 *) Add a new LogFormat directive, %c, that will log connection
4811 status at the end of the response as follows:
4812 'X' - connection aborted before the response completed.
4813 '+' - connection may be kept-alive by the server.
4814 '-' - connection will be closed by the server.
4817 *) Expand APR for WinNT to fully accept and return utf-8 encoded
4818 Unicode file names and paths for Win32, and tag the Content-Type
4819 from mod_autoindex to reflect that charset if the the feature
4820 macro APR_HAS_UNICODE_FS is true. [William Rowe]
4822 *) Compute the content length (and add appropriate header field) for
4823 the response when no content length is available and we can't use
4824 chunked encoding. [Jeff Trawick]
4826 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
4827 so that content input filters get dechunked data when using
4828 the default handler. Also removed REQUEST_CHUNKED_PASS.
4831 *) Add mod_ext_filter as an experimental module. This module allows
4832 the administrator to use external programs as filters. Currently,
4833 only filtering of output is supported. [Jeff Trawick]
4835 *) Most Apache functions work on EBCDIC machines again, as protocol
4836 data is now translated (again). [Jeff Trawick]
4838 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
4839 the EBCDIC support. They are noops on ASCII machines, so this
4840 type of translation doesn't have to be surrounded by #ifdef
4841 CHARSET_EBCDIC. [Jeff Trawick]
4843 *) Fix mod_include. tag commands work again, and the server will
4844 send the FAQ again. This also allows mod_include to set aside
4845 buckets that include partial buckets.
4846 [Ryan Bloom and David Reid]
4848 *) Add suexec support back. [Manoj Kasichainula]
4850 *) Lingering close now uses the socket directly instead of using
4851 BUFF. This has been tested, but since all we can tell is that it
4852 doesn't fail, this needs to be really hacked on.
4855 *) Allow filters to modify headers and have those headers be sent to
4856 the client. The idea is that we have an http_header filter that
4857 actually sends the headers to the network. This removes the need
4858 for the BUFF to send headers.
4861 *) Charset translation: mod_charset_lite handles translation of
4862 request bodies. Get rid of the xlate version of ap_md5_digest()
4863 since we don't compute digests of filtered (e.g., translated)
4864 response bodies this way anymore. (Note that we don't do it at
4865 all at the present; somebody needs to write a filter to do so.)
4868 *) Input filters and ap_get_brigade() now have a input mode parameter
4869 (blocking, non-blocking, peek) instead of a length parameter.
4872 *) Update the mime.types file to the registered media types as
4873 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
4876 *) Namespace protect some macros declared in ap_config.h
4879 *) Support HTTP header line folding with input filtering.
4882 *) Mod_include works again. This should still be re-written, but at
4883 least now we can serve an SHTML page again.
4886 *) Begin to remove BUFF from the core. Currently, we keep a pointer
4887 to both the BUFF and the socket in the conn_rec. Functions that
4888 want to use the BUFF can, functions that want to use the socket,
4889 can. They point to the same place.
4892 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
4893 [Tomas "Ögren" <stric@ing.umu.se>]
4895 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
4896 associated pool goes away. (APR pipes on OS/2 were already had this
4897 logic.) This resolvs a fatal file descriptor leak with CGIs.
4900 *) The final line of the config file was not being read if there was
4901 no \n at the end of it. This was caused by apr_fgets returning
4902 APR_EOF even though we had read valid data. This is solved by
4903 making cfg_getline check the buff that was returned from apr_fgets.
4904 If apr_fgets return APR_EOF, but there was data in the buf, then we
4905 return the buf, otherwise we return NULL.
4908 *) Piped logs work again in the 2.0 series.
4911 *) Restore functionality broken by the mod_rewrite security fix:
4912 rewrite map lookup keys and default values are now expanded
4913 so that the lookup can depend on the requested URI etc.
4914 PR #6671 [Tony Finch]
4916 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
4917 security bug in some mass virtual hosting configurations
4918 that can allow a remote attacker to retrieve some files
4919 on the system that should be inaccessible. [Tony Finch]
4921 *) Add a pool bucket type. This bucket is used for data allocated out
4922 of a pool. If the pool is cleaned before the bucket is destroyed, then
4923 the data is converted to a heap bucket, allowing it to survive the
4927 *) Add a flush bucket. This allows modules to signal that the filters
4928 should all flush whatever data they currently have. There is no way
4929 to actually force them to do this, so if a filter ignores this bucket,
4930 that's life, but at least we can try with this.
4933 *) Add an output filter for sub-requests. This filter just strips the
4934 EOS bucket so that we don't confuse the main request's core output
4935 filter by sending multiple EOS buckets. This change also makes sub
4936 requests start to send EOS buckets when they are finished.
4939 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
4940 makes ap_bucket_destroy a return void, which is okay because it
4941 used to always return APR_SUCCESS, and nobody ever checked its
4942 return value anyway.
4943 [Cliff Woolley <cliffwoolley@yahoo.com>]
4945 *) Remove the index into the bucket-type table from the buckets
4946 structure. This has now been replaced with a pointer to the
4947 bucket_type. Also add some macros to test the bucket-type.
4950 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
4951 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
4952 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
4953 All _VAR_ flavors changes to _DATA to be absolutely clear.
4956 *) Add support for /, //, //servername and //server/sharename
4957 parsing of <Directory> blocks under Win32 and OS2.
4958 [Tim Costello, William Rowe, Brian Harvard]
4960 *) Remove the function pointers from the ap_bucket type. They have been
4961 replaced with a global table. Modules are allowed to register bucket
4962 types and use then use those buckets.
4965 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
4966 once we finish writing the request body to the cgi child process;
4967 otherwise, the client doesn't hit EOF on stdin. Small request bodies
4968 worked without this change (for reasons I don't understand), but large
4969 ones didn't. [Jeff Trawick]
4971 *) Remove file bucket specific information from the ap_bucket type.
4972 This has been moved to a file_bucket specific type that hangs off
4973 the data pointer in the ap_bucket type.
4976 *) Input filtering now has a third argument. This is the amount of data
4977 to read from lower filters. This argument can be -1, 0, or a positive
4978 number. -1 means give me all the data you have, I'll deal with it and
4979 let you know if I need more. 0 means give me one line and one line
4980 only. A positive number means I want no more than this much data.
4982 Currently, only 0 and a positive number are implemented. This allows
4983 us to remove the remaining field from the conn_rec structure, which
4987 *) Big cleanup of the input filtering. The goal is that http_filter
4988 understands two conditions, headers and body. It knows where it is
4989 based on c->remaining. If c->remaining is 0, then we are in headers,
4990 and http_filter returns a line at a time. If it is not 0, then we are
4991 in body, and http_filter returns raw data, but only up to c->remaining
4992 bytes. It can return less, but never more.
4993 [Greg Ames, Ryan Bloom, Jeff Trawick]
4995 *) mod_cgi: Write all of the request body to the child, not just what
4996 the kernel would accept on the first write. [Jeff Trawick]
4998 *) Back out the change that moved the brigade from the core_output_filters
4999 ctx to the conn_rec. Since all requests over a given connection
5000 go through the same core_output_filter, the ctx pointer has the
5004 *) Fix another bug in the send_the_file() read/write loop. A partial
5005 send by apr_send would cause unsent data in the read buffer to
5006 get clobbered. Complete making send_the_file handle partial
5007 writes to the network.
5010 *) Fix a couple of type fixes to allow compilation on AIX again
5011 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
5013 *) Fix bug in send_the_file() which causes offset to be ignored
5014 if there are no headers to send.
5017 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
5018 filter. Useful for supporting Windows 9* with a binary
5019 compiled on Windows NT.
5022 Changes with Apache 2.0a7
5024 *) Reimplement core_output_filter to buffer/save bucket brigades
5025 across multiple calls to the core_filter. The brigade will be
5026 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
5027 thresholds are hit or the EOS bucket is received.
5030 *) Create experimental filter (buffer_filter) that coalesces bytes
5031 into one large buffer before invoking the next filter in the
5032 chain. This filter is particularly useful with the current
5033 implementation of mod_autoindex when it inserted above the
5034 chunk_filter. mod_autoindex generates a lot of brigades that
5035 containing buckets holding just a few bytes each. The
5036 buffer_filter coalesces these buckets into a single large bucket.
5039 *) Add apr_sendfile() support into the core_output_filter.
5042 *) Add apr_sendv() support into the core_output_filter.
5045 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
5046 [Mike Abbott <mja@sgi.com>]
5048 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
5049 make much sense, because Apache uses buckets instead of BUFFs now.
5052 *) send_the_file now falls back to a read/write loop on platforms that
5053 do not have sendfile.
5054 [Ryan Bloom and Brian Havard]
5056 *) Install apachectl correctly, and substitute the proper values so
5057 that it works again. [Ryan Bloom]
5059 *) Better(??) handle platforms that lack sendfile().
5062 *) APR now has UUID generation/formatting/parsing support.
5065 *) Begin the http_filter. This is an input filter that understands
5066 the absolute basic amount required to parse an HTTP Request. The
5067 goal is to be able to split headers from request body before passing
5068 the data back to the other filters.
5071 *) Bring forward from 1.3.13 the config directory implementation
5074 *) install apxs if it is created
5077 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
5078 conversions. [William Rowe]
5080 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
5081 ap_add_output_filter(). [Jeff Trawick]
5083 *) Multiple build and configuration fixes
5086 -add datadir and localstatedir substitutions
5088 -fix logfilename misspelling
5089 -fix evaluation of installation dir variables and
5090 -replace $foobar by $(foobar) to be usefull in the makefile
5094 -add rules for cross-compiling in rules.mk. Okay, rule to check for
5095 $CC_FOR_BUILD is still missing
5096 -use CHECK_TOOL instead of CHECK_PROG for ranlib
5097 -add missing "AR=@AR@" to severaly Makefile.in's
5098 -cache result for "struct rlimit"
5099 -compile all helper programs with native and cross compiler
5100 and use the native version to generate header file
5101 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
5103 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
5105 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
5107 *) Fix a bug where a client which only sends \n to delimit header
5108 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
5109 message. Start working on ebcdic co-existance with input
5111 [William Rowe, Greg Ames]
5113 *) If mod_so is enabled in the server always create libexec, even
5114 if there are no modules installed in this directory. This is a
5115 requirement for APXS to work correctly.
5118 *) Connection oriented output filters are now stored in the
5119 conn_rec instead of the request_rec. This allows us to add the
5120 output filter in the pre-connection phase instead of the
5121 post_read_request phase, which keeps us from trying to write an
5122 error page before we have a filter to write to the network.
5123 [Ryan Bloom, Jeff Trawick, and Greg Ames]
5125 *) Cleaning up an mmap bucket no longer deletes the mmap. An
5126 mmap can be used across multiple buckets (default_handler with
5127 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
5128 the mmap itself can't be associated with the bucket.
5131 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
5134 *) Radical surgery to improve mod_isapi support under Win32.
5135 Includes a number of newer ServerSupportFunction calls, support
5136 for ReadClient (in order to retrieve POSTs greater than 48KB),
5137 and general bug fixes to more reliably load ISAPI .dll's and
5138 prevent leaking handle resources. Note: There are still
5139 discrepancies between IIS's and Apache's ServerVariables, and
5140 async calls are still not supported. Additional warnings are
5141 logged to facilitate debugging of unsupported ISAPI calls.
5144 *) Add input filtering to Apache. The basic idea for the input
5145 filters is the same as the ideas for output filters. The biggest
5146 difference is that instead of calling ap_pass_brigade, ap_get_brigade
5147 should be called, and the order of execution for the filter itself is
5148 different. When writing an output filter, a brigade is passed in,
5149 and filters operate directly on that brigade, when done, they call
5150 ap_pass_brigade. Input filters are the exact opposite. Because input
5151 is not a push operation, filters first call ap_get_brigade. When this
5152 function returns, the input filter will be left with a valid brigade.
5153 The input filter should then operate on the brigade, and return.
5156 *) Fix building on BSD/OS using its native make. The build system
5157 falls back to the BSD .include directive on that host platform.
5160 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
5161 SHA1 and plaintext password encodings. Make feature tests a
5162 bit more flexible. [William Rowe]
5164 *) Charset translation: mod_charset_lite handles output content
5165 translation in a filter. mod_charset_lite no longer ignores
5166 subrequests. A bunch of cruft related to BUFF's support for
5167 translating request and response bodies was removed.
5170 *) Move the addition of the CORE filter to the post_read_request
5171 hook in http_core.c. This removes the need to add the filter in
5172 multiple places and allows for an SSL module to be added much
5173 simpler. [Ryan Bloom]
5175 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
5176 Fix a security problem that affects certain configurations of
5177 mod_rewrite. If the result of a RewriteRule is a filename that
5178 contains expansion specifiers, especially regexp backreferences
5179 $0..$9 and %0..%9, then it may be possible for an attacker to
5180 access any file on the web server. [Tony Finch]
5182 *) Fix a bug where errors that are detected during early request parsing
5183 don't produce visible HTTP error messages at the browser, because
5184 the core_filter wasn't present. [Greg Ames]
5186 *) Provide apr_socklen_t as a portability aid.
5187 [Victor J. Orlikowski]
5189 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
5190 as well as a comment arg to the add, adduser and update cmds.
5191 update allows the user to clear or preserve pw/groups/comment.
5192 Fixed a bug in dbmmanage that prevented the check option from
5193 parsing a password followed by :group... text. Corrected the
5194 seed calcualation for Win32 systems, and added -lsdbm support.
5197 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
5200 *) Avoid a segfault when parsing .htaccess files. An
5201 uninitialized tree pointer was passed to ap_build_config().
5204 *) Change the way that inet_addr & inet_network are checked for
5205 in APR's configure process to allow BeOS BONE to correctly
5206 find them. With this change BeOS BONE now builds from source
5207 with no problems. [David Reid]
5209 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
5210 the end of the parameters to execve() was stored in the wrong
5211 location, overlaying the storage beyond the newargs[] array and
5212 also passing uninitialized storage to execve(), which would
5213 sometimes fail with EFAULT. [Jeff Trawick]
5215 *) Fix a bug parsing configuration file containers. With a sequence
5216 like this in the config file
5218 <IfModule mod_kilroy.c>
5221 <IfModule mod_lovejoy.c>
5226 the second container would be terminated at the blank line due to
5227 sediment in the buffer from reading the prior </IfModule> and an
5228 error message would be generated for the real </IfModule> for the
5229 second container. Also due to this problem, any two characters
5230 could be used for "</" in the close of a container.
5233 *) ap_add_filter prototype changed to remove the ctx pointer. The
5234 pointer still remains in the filter structure, but it can not be
5235 a part of the ap_add_filter prototype. The reason is that when
5236 the core uses AddFilter to add a filter to the stack it doesn't
5237 know how to allocate the ctx pointer, or even how much memory should
5238 be allocated. The filters will have to be responsible for allocating
5239 the ctx memory when they need it.
5242 *) Add an AddFilter directive. This directive takes a list of filters
5243 that should be activated for the requested resource.
5246 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
5247 some other platforms). [Jeff Trawick]
5249 *) Modify mod_include to be a filter. Currently, it has only been tested
5250 on actual files, but it should work for CGI scripts too.
5253 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
5254 writes. apr_flush() for Unix: handle interrupted writes.
5257 *) NameVirtualHost can now take "*" as an argument instead of
5258 an IP address. This allows you to create a purely name-based
5259 virtual hosting server that does not have any IP addresses in
5260 the configuration file and which ignores the local address
5261 of any connections. PR #5595, PR #4455 [Tony Finch]
5263 *) Fix some compile warnings in mod_mmap_static.c
5264 [Mike Abbott <mja@sgi.com>]
5266 *) Fix chunking problem with CGI scripts. The general problem was that
5267 the CGI modules were adding an EOS bucket and then the core added an
5268 EOS bucket. The chunking filter finalizes the chunked response when it
5269 encounters an EOS bucket. Because two EOS buckets were sent, we
5270 finalized the response twice. The fix is to make sure we only send one
5271 EOS, by utilizing a flag in the request_rec.
5274 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
5275 and Win32. Previously, the first read from an apr_file_t set up via
5276 apr_put_os_file() would return a '\0'. [Jeff Trawick]
5278 *) Mod_cgid now creates a single element bucket brigade, with a pipe
5279 bucket, instead of using BUFF's and ap_r*.
5282 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
5283 [Mike Abbott <mja@sgi.com>]
5285 *) Remove ap_bopenf from buff code. This required modifying the file_cache
5286 code to use APR file's directly instead of going through BUFFs.
5289 *) Fix compile break on some platforms for mod_mime_magic.c
5290 [John K. Sterling <sterling@covalent.net>]
5292 *) Fix merging of AddDefaultCharset directive.
5293 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
5295 *) Minor revamp of the rlimit sections of code. We now test
5296 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
5297 is now "available" even if the platform doesn't support
5298 the rlimit family (it's just a noop though). [Jim Jagielski]
5300 *) Migrate the pre-selection of which MPM to use for specific
5301 platforms to hints.m4, which contains (or should contain)
5302 all platform specific "hints". [Jim Jagielski]
5304 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
5307 *) Add tables with non-string/binary values to APR.
5310 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
5313 *) Update PCRE to version 3.2. [Ryan Bloom]
5315 *) Change the way buckets' destroy functions are called so that
5316 they can be more directly used when changing the type of a
5317 bucket in place. [Tony Finch]
5319 *) Add generic support for reference-counting the resources used by
5320 buckets, and alter the HEAP and MMAP buckets to use it. Change
5321 the way buckets are initialised to support changing the type of
5322 buckets in place, and use it when setting aside TRANSIENT buckets.
5323 Change the implementation of TRANSIENT buckets so that it can be
5324 mostly shared with IMMORTAL buckets, which are now implemented.
5327 Changes with Apache 2.0a6
5329 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
5331 *) Add a chunking filter to Apache. This brings us one step closer
5332 to removing BUFF. [Ryan Bloom]
5334 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
5335 added to the stack is the last filter to be called. [Ryan Bloom]
5337 *) Apache 2.0 has been completely documented using Scandoc. The
5338 docs can be generated by running 'make docs'. [Ryan Bloom]
5340 *) Add filtered I/O to Apache. This is based on bucket brigades,
5341 Currently the buckets still use BUFF under the covers, but that
5342 should change quickly. The only currently written filter is the
5343 core filter which just calls ap_bwrite. [The Apache Group]
5345 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
5346 built with thread support. [Jeff Trawick]
5348 *) Abort configuration if --with-layout was specified and there's
5349 no layout definition file. [Ken Coar]
5351 *) Add support for '--with-port=n' option to configure. [Ken Coar]
5353 *) Add support for extension methods for the Allow response header
5354 field, and an API routine for accessing r->allowed and the
5355 list of extension methods in a unified manner. [Ken Coar]
5357 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5358 [Rob Simonson <simo@us.ibm.com>]
5360 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5361 APACHE_XLATE builds. [Jeff Trawick]
5363 *) A configuration file parsing problem was fixed. When the
5364 configuration file started with an IfModule/IfDefine container,
5365 only the last statement in the container would be retained.
5368 Changes with Apache 2.0a5
5370 *) Perchild is serving pages after passing them to different child
5371 processes. There are still a lot of bugs, but this does work. I
5372 have made requests against the same installation of Apache, and had
5373 different servers use different user IDs to serve the responses.
5374 This change moves to using socketpair instead of an AF_UNIX socket.
5377 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5378 It can't seem to pass between child processes yet, but I think we
5379 are closer now than before. This moves us back to using Unix
5380 Domain Sockets. [Ryan Bloom]
5382 *) libapr functions and types renamed with apr_ prefix.
5383 #include "apr_compat.h" for 1.3.x backwards compat
5386 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5387 return the right information on the local socket address.
5388 [Gregory Nicholls <gnicholls@level8.com>]
5390 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5391 [Gregory Nicholls <gnicholls@level8.com>]
5393 *) Add an option to not detach from the controlling terminal without
5394 going into single process mode. This allows for much easier
5395 debugging of the process startup code. [Ryan Bloom]
5397 *) ab: don't use perror() to report the failure of an APR function.
5400 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5401 scoreboard on graceful restarts.
5404 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5405 An invalid ap_proc_t was passed to ap_create_process().
5408 *) Allow modules to register filters. Those filters are still
5409 never called, but this is a step in the right direction.
5410 [Ryan Bloom and Greg Stein]
5412 *) Register the mod_cgid daemon process for cleanup so that it is
5413 killed at termination if it does not die when the parent gets
5414 SIGTERM. This change is to fix occasional problems where the
5415 process stays around. Bugs in similar logic in mod_rewrite and
5416 mod_include were also fixed. [Jeff Trawick]
5418 *) Fix a bug in the time handling. Basically, we were imploding a time
5419 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5420 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5421 uses those two fields to adjust the time value. Because of the HTTP
5422 spec, both of those values can be zero'ed out safely. This fixes
5423 the bug correctly. [Ryan Bloom]
5425 *) Fix a couple of place in the Windows code where the wrong error
5426 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
5428 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5430 *) Added the APR_EOL_STR macro for platform dependent differences in
5431 logfiles and other raw text (such as all APR files). Fixes logfiles
5432 not terminated with cr/lf sequences in Win32. [William Rowe]
5434 *) Move all strings functions in APR to src/lib/apr/strings and create
5435 apr_strings.h for the prototypes. [Ryan Bloom]
5437 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5438 to repeat the syscall until we stop getting EINTR. I noticed a
5439 related problem at termination (SIGTERM) on FreeBSD when using
5440 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5441 implementation work properly with child init. Previously, ap_lock()
5442 was essentially a no-op because all children were using different
5443 locks and thus nobody ever blocked. [Jeff Trawick]
5445 *) The htdocs/ tree has been moved out of the CVS source tree into
5446 a separate area for easier development. This has NO EFFECT on
5447 end-users or Apache installations. [Ken Coar]
5449 *) Integrate the mod_dav module for WebDAV protocol handling. This
5450 adds the dav and dav_fs modules, the SDBM library, and additional
5451 XML handling utilities. [Greg Stein]
5453 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
5456 *) Update the lib/expat-lite/ library (bring forward changes from
5457 the Apache 1.3 repository). [Greg Stein]
5459 *) If sizeof(long long) == sizeof(long), then prefer long in APR
5460 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
5462 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
5463 machines where sendfile is detected, but nobody has written ap_sendfile.
5464 [Dave Hill <ddhill@zk3.dec.com>]
5466 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
5468 *) ab would start up more connections than needed, then quit when the
5469 desired number were finished. Also fixed a logic error involving
5470 ab keepalives. [Victor J. Orlikowski]
5472 *) WinNT: Implement non-blocking pipes with timeouts to communicate
5473 with CGIs. Apache 2.0a4 had non-blocking pipes but without
5474 timeouts (i.e, if a timeout was specified, the pipe reverted to
5475 a full blocking pipe). Now the behaviour is more in line with
5476 Unix non-blocking pipes.
5479 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
5480 cache open file handles along with accept socket reuse enables
5481 Apache 2.0 to serve non-keepalive requests for static files at
5482 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
5483 and Apache 2.0 will serve almost 1200 rps on my system).
5486 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
5487 supports two config directives, mmapfile (same behavious as
5488 mod_mmap_static) and cachefile. Use the cachefile directive
5489 to cache open file handles. This directive only works on systems
5490 that have implemented the ap_sendfile API. cachefile works today
5491 on Windows NT, but has not been tested on any flavors of Unix.
5494 *) Cleanup the configuration. With the last few changes the
5495 configuration process automatically:
5496 inherits information about how to build from APR. Allowing
5497 APR to inform Apache that it should or should not use -ldl
5499 Detects which mod_cgi should be used mod_cgi or mod_cgid,
5500 based on the threading model
5502 Apache calls APR's configure process before finishing it's
5503 configuration processing, allowing for more information flow
5508 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
5509 with non-zero argument makes the socket non-blocking. BeOS and
5510 OS/2 already worked this way. [Jeff Trawick]
5512 *) ap_close() now calls ap_flush() for buffered files, so write
5513 operations work a whole lot better on buffered files.
5516 *) Fix error messages issued from MPMs which explain where to change
5517 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
5520 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
5521 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
5522 now the way that the blocking state of a pipe is manipulated.
5523 ap_block_pipe() is gone. [Jeff Trawick]
5525 *) Correct the problem where the only local host name that the IP stack
5526 can discover are 'undotted' private names. If no fully qualified
5527 domain name can be identified, the default ServerName will be set to
5528 the machine's IP address string. A warning is always provided if the
5529 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
5531 *) Repair problems with config file processing which caused segfault
5532 at init when virtual hosts were defined and which caused ServerName to
5533 be ignored when there was no valid DNS setup. [Jeff Trawick]
5535 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
5537 *) Add ap_sendfile implementation for AIX
5538 [Victor J. Orlikowski]
5540 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
5541 apr_network_io.h, and apr_thread_proc.h.
5542 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
5544 *) Bring the allocation and pool debugging code back into a working
5545 state. This will need to be tested as so far it's only been used on
5548 *) Change configuration command setup to be properly typesafe when in
5549 maintainer mode. Note that this requires a compiler that can initialise
5550 unions. [Ben Laurie]
5552 *) Turn on buffering for config file reads. Part of this was to
5553 repair buffered I/O support in Unix and implement buffered
5554 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
5556 *) Win32: Fix problem where UTC offset was not being set correctly
5557 in the access log. Problem reported on news group by Jerry Baker.
5560 *) Fix segfault when reporting this type of syntax error:
5561 "</container> without matching <container> section", where
5562 container is VirtualHost or Directory or whatever.
5565 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
5566 Prevent the source code for CGIs from being revealed when
5567 using mod_vhost_alias and the CGI directory is under the document root
5568 and a user makes a request like http://www.example.com//cgi-bin/cgi
5569 as reported in <news:960999105.344321@ernani.logica.co.uk>
5572 *) Add support for the new Beos NetwOrking Environment (BONE)
5575 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
5576 final input char is incomplete; ap_bwrite_xlate() now handles
5577 incomplete final input chars. [Jeff Trawick]
5579 *) Yet another update to saferead/halfduplex stuff -- need to ensure
5580 that a bhalfduplex call occurs before logging or else DNS and
5581 such can delay the last packet of the response. [Dean Gaudet]
5583 *) Some syscall reduction in APR on unix -- don't seek when setting
5584 up an mmap; and don't fcntl() more than once per socket.
5587 *) When mod_cgid is started as root, the cgi daemon now switches
5588 to the configured User/Group (like other httpd processes)
5589 instead of continuing as root. [Jeff Trawick]
5591 *) The prefork MPM now uses an APR lock for the accept() mutex.
5592 It has not been getting a lock at all recently. httpd -V now
5593 displays APR's selection of the lock mechanism instead of the
5594 symbols previously respected by prefork. [Jeff Trawick]
5596 *) Change the mmap() feature test to check only for existence.
5597 The previous check required features not used by Apache.
5600 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
5601 sometimes mangled. The len parm to accept() was not
5602 initialized, leading sometimes to an endless loop of failed
5603 accept() calls on OS/390 and anywhere else that failed the call
5604 if the len was negative. Use <sys/un.h> for struct sockaddr_un
5605 instead of declaring it ourselves to fix a compilation problem
5606 on Solaris. [Jeff Trawick]
5608 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
5610 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
5612 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
5614 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
5615 initialization if ALLOC_DEBUG is defined; no known symptom
5616 otherwise. [Jeff Trawick]
5618 *) Fix typo in configure script when checking for mod_so. bash
5619 doesn't seem to have a problem but /bin/sh on Solaris does.
5620 Symptom: "./configure: test: unknown operator =="
5623 *) Rebind the Win32 NT and 9x services control into the MPM.
5624 All console, WinNT SCM and Win9x pseudo-service control code is
5625 now wrapped within the WinNT MPM.
5628 *) Make a copy of getenv("PATH") before storing for later use. Some
5629 getenv() implementations use the same storage for successive calls.
5630 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
5632 *) Server Tokens work in 2.0 again. This also propogates the change
5633 to allow just the product name in the server string using
5637 Changes with Apache 2.0a4
5639 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
5640 won't need to call it. [Greg Ames, Jeff Trawick]
5642 *) Move pre_config hook call to between configuration read and config
5643 tree walk. This allows all modules to implement pre_config hooks
5644 and know that they will be called at an appropriate time.
5647 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
5650 *) Add pre-config hooks back to all modules.
5653 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
5654 ContentDigest enabled and we can't/don't mmap the file.
5657 *) We now report the correct line number for syntax errors in config
5658 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
5660 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
5661 related bugs, and changed shmem/locking to use apr API. Shared-mem
5662 is currently disabled, however, because of problems with graceful
5663 restarts. [Ronald Tschalär]
5665 *) Fix corruption of IFS variable in --with-module= handling.
5666 Depending on the user's shell or customization thereof, there
5667 would be errors generating ap_config_auto.h later in the configure
5668 procedure. [Jeff Trawick]
5670 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
5671 isn't used (as in 1.3), except that on Unix it is now logged via
5672 ap_log_rerror() instead of by the child having STDERR_FILENO refer
5673 to the error log. [Greg Ames, Jeff Trawick]
5675 *) Add '-D' argument processing for run time configuration defines.
5678 *) Organize http_main.c as independent code, such that no code or
5679 global data is exported from it. WIN32 will dynamically link it
5680 to the server core, so this will prevent mutual dependency.
5683 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
5684 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
5687 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
5688 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
5690 *) Add mod_charset_lite for configuring character set translation.
5693 *) Add '-n' option to htpasswd to make it print its user:pw record
5694 on stdout rather than having to frob a text file. [Ken Coar]
5696 *) Fix saferead. Basically, we flush the output buffer if a read on the
5700 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
5701 a conversion is single-byte only. [Jeff Trawick]
5703 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
5704 the BeOS 5.0 documentation says that shutdown doesn't work yet.
5707 *) Fix some minor errors where pid was being manipulated as an int
5708 instead of the portable pid_t. [Roy Fielding]
5710 *) Fix some error log prints that were printing the pointer to a
5711 structure rather than the pid within the structure.
5712 [Jeff Trawick, Roy Fielding]
5714 *) ab: Fix a command-line processing bug; track bad headers in
5715 err_response; support reading headers up to 2K.
5716 [Ask Bjoern Hansen <ask@valueclick.com>]
5718 *) Fix ap_resolve_env() so that it handles new function added in a prior
5719 alpha (see "Added the capability to do ${ENVVAR} constructs in the
5720 config file.") as well as the constructs used by mod_rewrite.
5721 [Paul Reder <rederpj@raleigh.ibm.com>]
5723 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
5725 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
5726 APR to perform translation, instead of accessing the hard-coded tables
5727 in 1.3's ebcdic.c. [Jeff Trawick]
5729 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
5732 *) Add the ability to hook into the config file reading phase. Basically
5733 if a directive is specified EXEC_ON_READ, then when that directive is
5734 read from the config file, the assocaited function is executed. This
5735 should only be used for those directives that must muck with HOW the
5736 server INTERPRETS the config. This should not be used for directives
5737 that re-order or replace items in the config tree. Those changes should
5738 be made in the pre-config step.
5741 *) Add mod_example to the build system.
5744 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
5745 byte character sets. [Jeff Trawick]
5747 *) Pick up various EBCDIC fixes from 1.3 (from Martin
5748 Kraemer and Oliver Reh originally according to the change log).
5751 *) Fix a couple of problems in RFC1413 support (controlled by the
5752 IdentityCheck directive). Apache did not build the request string
5753 properly and more importantly Apache would loop forever if the
5754 would-be ident server dropped the connection before sending a
5755 properly terminated response. [Jeff Trawick]
5757 *) apxs works in 2.0.
5760 *) Reliable piped logs work in 2.0.
5763 *) Introduce a hash table implementation into APR to be used for
5764 replacing tables and other random data structures in Apache.
5767 *) Add some more error reporting to htpasswd in the case of problems
5768 generating or accessing the temporary file. Also, pass in a
5769 buffer if the implementation knows how to use it (i.e., if L_tmpnam
5770 is defined). [Ken Coar]
5772 *) Configure creates config.nice now containing your configure
5773 options. Syntax: ./config.nice [--more-options]
5776 *) Fix various return code problems in APR on Win32. For most of
5777 these, APR was returning APR_EEXIST instead of GetLastError()/
5778 WSAGetLastError(). [Jeff Trawick]
5780 *) Make piped logs work again in version 2.0
5783 *) Add VPATH support to UNIX build system of Apache and APR.
5786 *) Fix ap_tokenize_to_argv to respect the const arguments that are
5790 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
5791 Patch submitted to author.
5794 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
5795 /sbin in PATH on FreeBSD (all submitted to rse previously)
5798 *) Fix building Pthread-based MPMs on OpenBSD
5799 [Sascha Schumann] PR#26
5801 *) Fix ap_readdir() problem on systems where d_name[] field in
5802 struct dirent is declared with only one byte. (This problem only
5803 affected multithreaded builds.) This caused a segfault during
5804 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
5805 least). [Jeff Trawick]
5807 *) Fix some make-portability problems on at least Tru64, Irix
5809 [Sascha Schumann] PR#18, PR#39
5811 *) Add ap_sigwait() to support old-style sigwait() on systems
5812 like OS/390 and UnixWare.
5815 *) Add POSIX-thread flags for more platforms.
5818 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
5819 (on Unix, at least) to handle resolver errors. Fix a bug in
5820 the definition of APR_ENOMEM so that ap_strerror() can spit
5821 out the correct error message for it.
5824 Changes with Apache 2.0a3
5826 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
5829 *) API: *HOOK* macros now have an AP_ prefix
5832 *) Win32: Eliminate redundant calls to initialize winsock.
5833 [Tim Costello <timcostello@ozemail.com.au>]
5835 *) Fix bugs initializing ungetchar for pipes.
5836 [Chia-liang Kao <clkao@CirX.ORG>]
5838 *) The ab program in the src/support directory is now portable using
5842 *) Support directory is being compiled when the server is built
5845 *) The configure option --with-program-name has been added to allow
5846 developers to rename the executable at configure time. This also
5847 changes the name of the config files to match the executable's name.
5850 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
5851 containing version numbers. [Martin Pool]
5853 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
5854 Unix; access_log and error_log now created with these perms; non-
5855 Unix is unaffected [Jeff Trawick]
5857 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
5858 Replaced more magic numbers with MD5_DIGESTSIZE.
5859 [William Rowe, Roy Fielding]
5861 *) Win32: Get mod_auth_digest compiling and added to the Windows
5862 build environment. Not tested and I'd be suprised if it
5863 actually works. [Bill Stoddard]
5865 *) Revamp the Win32 make environment. Makefiles have been removed and
5866 Apache.dsw created to bring together all the pieces. Create new file
5867 os/win32/BaseAddr.ref to define module base addresses (to prevent
5868 dll relocation at start-up).
5869 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
5871 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
5872 of the \015, \012, and \015\012 constants with macros.
5875 *) Add ap_xlate_open() et al for translation of text between different
5876 character sets. The initial implementation requires iconv().
5879 *) More FAQs and answers from comp.infosystems.www.servers.unix.
5880 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5882 *) CGI output is being timed out now.
5885 *) Fix the problem with dieing quietly. dupfile now takes a pool which
5886 is used by the new apr file. There is no reason to create a new file
5887 with the same lifetime as the original file.
5890 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
5891 module base addresses. This will help shooting seg faults
5892 in the field. [William Rowe <wrowe@lnd.com>]
5894 *) Update Apache on Windows documentation. Add new document
5895 describing how to compile Apache on Windows.
5896 [William Rowe <wrowe@lnd.com>]
5898 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
5899 microseconds instead of seconds. Some storage leaks and other
5900 minor bugs in related code were fixed. [Jeff Trawick]
5902 *) Win32: First cut at getting mod_isapi working under 2.0
5903 [William Rowe <wrowe@lnd.com>]
5905 *) First stab at getting mod_auth_digest working under 2.0
5906 quick change summary:
5907 - moved the random byte generation (ap_generate_random_bytes) into APR
5908 - now uses ap_time_t
5909 - compiles and runs on linux
5911 [Brian Martin <bmartin@penguincomputing.com>]
5913 *) Win32: Move the space stripping of physical service names
5914 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
5915 unresolved symbol. Add dependency checking to the
5916 CreateService call to ensure TCPIP and AFP (winsock) is started
5918 [William Rowe <wrowe@lnd.com>]
5920 *) Win32: Add code to perform latebinding on functions that may
5921 not exist on all levels of Windows where Apache runs. This
5922 is needed to allow Apache to start-up on Win95/98. All calls
5923 to non portable functions should be protected with
5924 ap_oslevel checks to prevent runtime segfaults.
5925 [William Rowe <wrowe@lnd.com>]
5927 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
5929 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
5931 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
5932 This addresses PR 1623. Still need to address timing out runaway
5933 CGI scripts. [Bill Stoddard]
5935 *) Win32: Make ap_stat Windows 95/98 friendly
5936 [William Rowe <wrowe@lnd.com>]
5938 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
5939 always fail. Need to initialise the dwOSVersionInfoSize member of the
5940 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
5943 The patch also enhances ap_get_oslevel (and the associated enum) to
5944 handle selected service packs for NT4, and adds recognition for
5945 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
5946 we can use ReadFileScatter and WriteFileGather in readwrite.c.
5947 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
5949 *) Get mod_rewrite building and running, and mod_status building for Win NT
5950 [Allan Edwards <ake@raleigh.ibm.com>]
5952 *) Patch to port mod_auth_db to the 2.0 api and also to support
5953 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
5954 2.7.7. It should work with version 1 as well but I haven't tested it.
5955 [Brian Martin <bmartin@penguincomputing.com>]
5957 *) Get APR DSO code working under Windows. Includes cross platform
5959 [Tim.Costello@BTFinancialgroup.com]
5961 *) Fix some of the Windows APR time functions.
5964 *) FAQ changes related to tidying up historical documents on the web site.
5965 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5967 *) Move Windows DSO code into APR.
5970 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
5971 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
5972 at build time. At this point, the server will not compile on Windows because
5973 of the recent DSO commits. Fixing those next.
5974 [Bill Rowe & Bill Stoddard]
5976 *) Added error checking for file I/O APR routines.
5977 [Jon Travis <jtravis@covalent.net>]
5979 *) APR: Don't use the values of resolver error codes for the
5980 corresponding APR error codes. On Unix and Win32, return the
5981 proper APR error code after a resolver error. [Jeff Trawick]
5983 Changes with Apache 2.0a2
5985 *) Renamed the executable back to httpd on all platforms other
5989 *) Allow BeOS to survive restarts, log properly and a few
5990 small things it had problems with due to the way it setup
5991 users and groups. [David Reid]
5993 *) Get mod_rewrite working with APR locks
5994 [Paul Reder <rederpj@raleigh.ibm.com>]
5996 *) Actually remove the sempahore when the lock cleanup routine
5997 is called on BeOS. [David Reid]
5999 *) Clear hook registrations between reads of the config file.
6000 When DSOs are unloaded and re-loaded the old hook pointers may
6001 no longer be valid. This fix eliminates potential segfaults.
6002 [Allan Edwards <ake@raleigh.ibm.com>]
6004 *) Fix a problem with Sigfunc not being defined or bypassed
6005 if sigaction() wasn't found. [Jim Jagielski]
6007 *) Fix the locking mechanism on BSD variants. They now use fcntl
6008 locks. This allows the server to start and serve pages.
6011 *) First cut at getting the Win32 installer to work
6012 [William Rowe <wrowe@lnd.com>]
6014 *) Get htpasswd compiling under Windows
6015 [William Rowe <wrowe@lnd.com>]
6017 *) Change the log message for a bind() failure to show the
6018 interface and port number. [Jeff Trawick]
6020 *) Import the documentation from 1.3.12 and bring parts of it
6021 up-to-date with respect to the changes that have occurred
6025 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
6026 now logged correctly on BeOS.
6029 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
6030 Makefile.win includes the same user interface as the old
6032 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
6034 *) Win32 exec now uses COMSPEC environment string for command
6035 shell path resolution.
6036 [William Rowe <wrowe@lnd.com>] PR#3715
6038 *) Win32: ap_connect() was not returning correct error condition
6040 [Allen Prescott <allen@clanprescott.com>]
6042 *) Win32: ap_open() was broken on Win9x because an NT-specific
6043 flag was passed to CreateFile. ap_puts() added an unnecessary
6045 [Jeff Trawick <trawick@us.ibm.com>]
6047 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
6048 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
6049 confusing ee/et name and made all extensions language/dialect
6050 rather than country reflecting. Changed example files to
6051 explicit reflect the ISO charset and added a few common
6052 ones to the example config [dirkx]
6054 *) Extend external module capability. To use this, you call
6055 configure with --with-module=path/to/mod1,path/to/mod2,etc.
6058 *) Backported the various "default charset" fixes from 1.3.12,
6059 including the AddDefaultCharset directive. [Jim Jagielski]
6061 *) Added the capability to do ${ENVVAR} constructs in the
6062 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
6063 it does this on a line by line basis; i.e. if the envvar
6064 expands to something with spaces you have to protect it
6065 by adding quotes around it (Unless of course you expect it
6066 to contains more than one argument. Alternatively you
6067 can compile it on a per token basis; which is what people
6068 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
6069 hampers fancier hacks.
6070 [Dirk-Willem van Gulik]
6072 *) Changed the 'ErrorDocument' syntax in that it NO longer
6073 supports the asymetric
6075 ErrorDocument 301 "Some message
6077 Note the opening " quote, without a closing quote. It now
6078 has either the following syntaxes
6080 ErrorDocument XXX /local/uri
6081 ErrorDocument XXX http://valid/url
6082 ErrorDocument XXX "Some Message"
6084 The recognition heuristic is: if it has a space it
6085 is a message. If it has no spaces and starts with a /
6086 or is a valid URL then treat it that way. Otherwise it
6087 is assumed to be a message.
6089 This breaks backward compatibility but makes live a hell
6090 of a lot easier for GUI's and config file parsers.
6091 [Dirk-Willem van Gulik]
6093 *) Changed 'CacheNegotiatedDocs' from its present/not-present
6094 syntax into a 'on' or 'off' syntax. As it currently is the
6095 only non nesting token which uses NO_ARGS and thus is an
6096 absolute pain for any config interface automation. This
6097 breaks backward compatibility. [Dirk-Willem van Gulik]
6099 *) Add ability to add external modules to the build process. This is
6100 done with --with-module=/path/to/module. Modules can only be added
6101 as static modules at this point.
6104 Changes with Apache 2.0a1
6106 *) Fix FreeBSD 3.3 core dump.
6107 Basically, ap_initialize() needs to get called before
6108 create_process(), since create_process() passes op_on structure
6109 to semop() to get a lock, but op_on isn't initialized until
6110 ap_initialize() calls setup_lock(). Here is a slight
6111 rearrangement to main() which calls ap_initialize() earlier...
6112 [Jeff Trawick <trawick@us.ibm.com>]
6114 *) Enable Apache to use sendfile/TransmitFile API
6115 [Bill Stoddard, David Reid, Paul Reder]
6117 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
6121 *) Make file I/O and network I/O writev/sendv APIs consistent.
6122 Eliminate use of ap_iovec_t and use Posix struct iovec.
6123 Use seperate variable on ap_writev to set the number of iovecs
6124 passed in and number of bytes written.
6127 *) Adapt file iol to use APR functions. Replaced ap_open_file()
6128 with ap_create_file_iol(). ap_create_file_iol() requires that
6129 the file be opened prior to the call using ap_open().
6132 *) Port mod_include and mod_cgi to 2.0
6133 [Paul Reder, Bill Stoddard]
6135 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
6136 bytes_read/bytes_written is always valid (never -1). Plus
6137 some fixes to buff.c to correct problems introduced by the
6138 errno => ap_status_t changes a while back. Plus a fix to
6139 chunked encoding introduced right at the beginning of 2.0.
6142 *) Revamped UNIX build system to use autoconf and libtool.
6143 [Manoj Kasichainula, Sascha Schumann]
6145 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
6147 *) SECURITY: More rigorous checking of Host: headers to fix security
6148 problems with mass name-based virtual hosting (whether using mod_rewrite
6149 or mod_vhost_alias).
6150 [Ben Hyde, Tony Finch]
6152 *) Add back support for UseCanonicalName in <Directory> containers.
6153 [Manoj Kasichainula]
6155 *) Added APLOG_STARTUP log type. This allows us to write an error
6156 message without any of the date and time information. As a part
6157 of this change, I also removed all of the calls to fprintf(stderr
6158 and replaced them with calls to ap_log_error using APLOG_STARTUP
6159 writing to stderr is no longer portable, because we don't direct
6160 stderr to the error log on all platforms.
6163 *) Convert error logging functions to take errno as an argument.
6164 This makes our error logs more portable, because some Windows API's
6165 don't set errno. This change allows us to still output a valid
6166 message on all of our platforms.
6169 *) mod_mime_magic runs in 2.0-dev now.
6170 [Paul Reder <rederpj@raleigh.ibm.com>]
6172 *) sendfile has been added to APR.
6173 [John Zedlewski <zedlwski@Princeton.EDU>]
6175 *) buff.c has been converted to no longer use errno.
6176 [Manoj Kasichainula]
6178 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
6179 interface adaption to APR functions did it. [Martin Kraemer]
6181 *) Support DSOs properly on 32-bit HP-UX 11.0
6182 [Dilip Khandekar <dilip@cup.hp.com>]
6184 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
6185 [Ralf S. Engelschall]
6187 *) Cleaned APR build environment integration and bootstrap APR
6188 automatically for developers from src/Configure.
6189 [Ralf S. Engelschall]
6191 *) Fixed building of src/support/htpasswd.c
6192 [Ralf S. Engelschall]
6194 *) When generating the Location: header, mod_speling forgot
6195 to escape the spelling-fixed uri. (Forw-Port from 1.3)
6198 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
6200 *) Change all pools to APR contexts. This is the first step to
6201 incorporating APR into Apache. [Ryan Bloom]
6203 *) Move "handler not found" warning message to below the check
6204 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
6205 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
6207 *) Support line-continuation feature in config.option file and
6208 allow the loading of multiple option sections at once via
6209 ``--with-option=<section1>,<section2>,...''
6210 [Ralf S. Engelschall]
6212 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
6214 Changes with Apache MPM
6216 *) Use asynchronous AcceptEx() and a completion port to accept and
6217 dispatch connections to threads in Windows NT/2000.
6220 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
6223 *) Implement the APACI --with-option facility
6224 (per default used the config.option file).
6225 [Ralf S. Engelschall]
6227 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
6229 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
6230 Replace pre_connection module call with a register_hook call and
6231 implement pre_connection as a hook. The intent is that these hooks will
6232 be extended to allow Apache to be multi-protocol, and also to allow the
6233 calling order to be specified on a per-hook/per-module basis.
6236 *) Implement mpm_* methods as "modules". Each method gets its own
6237 subdir in src/modules (eg: src/modules/prefork). Selection
6238 of method uses Rule MPM_METHOD. [Jim Jagielski]
6240 *) Port the hybrid server from the apache-apr repository as
6241 mpm_mpmt_pthread. [Manoj Kasichainula]
6243 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
6244 amongst the unix MPMs.
6246 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
6247 signal handling for the new world order. [Dean Gaudet]
6249 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
6250 of alloc.c for now. [Dean Gaudet]
6252 *) Handle partial large writes correctly. [Ben Laurie]
6254 *) Eliminate conn_rec's pointer to server. All it knows is the base server
6255 based on IP/port. [Ben Laurie]
6257 *) Port a bunch of modules to the new module structure.
6258 ["Michael H. Voase" <mvoase@midcoast.com.au>]
6260 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
6262 *) Basic restructuring to introduce the MPM concept; includes various
6263 changes to the module API... better described by
6264 docs/initial_blurb.txt. [Dean Gaudet]
6266 Changes with Apache pthreads
6268 *) New buff option added: BO_TIMEOUT. It describes the timeout for
6269 buff operations (generally over a network).
6270 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
6272 *) Created http_accept abstraction. Added 4 new functions (not exported):
6273 init_accept(), begin_accepting_requests(), get_request(),
6274 stop_accepting_requests() [Bill Stoddard]
6276 *) Fix to ap_rprintf call that allows mod_info to work properly.
6277 [James Morris <jmorris@intercode.com.au>]
6279 *) user and ap_auth_type fields were moved from connection_rec to
6280 request_rec. [Ryan Bloom]
6282 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
6283 needed in a threaded server.
6285 *) Initial pthread implementation from from Dean's apache-nspr code.
6286 [Bill Stoddard, Ryan Bloom]
6289 Changes with Apache 1.3.9
6291 *) Remove bogus error message when a redirect doesn't set Location.
6292 Instead, use an empty string to avoid coredump if the error message
6293 was supposed to include a location. [Roy Fielding]
6295 *) Don't allow configure to include mod_auth_digest unless it is
6296 explicitly requested, even if the user asked for all modules.
6299 *) Translate module names to dll names for OS/2 so that they are no more
6300 than 8 characters long and have an extension of "dll" instead of "so".
6303 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
6304 Fix test-compile check to check for randbyte instead of trand32.
6305 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
6306 and tweak to make Amaya happier. [Ronald Tschalär]
6308 *) Ensure that the installed expat include files are world readable,
6309 just like the other header files. [Martin Kraemer]
6311 *) Fixed generated AddModule adjustments in APACI's `configure' script
6312 in order to allow (new) modules like mod_vhost_alias to be handled
6313 correctly (which was touched by the adjustments for mod_alias).
6314 [Ralf S. Engelschall]
6316 *) For binary builds, add -R flag to apachectl to work around the lack of
6317 an absolute path to the ./libexec directory where the libhttp.ep file
6318 is needed for SHARED_CORE architectures. [Randy Terbush]
6320 *) WIN32: Create the CGI script process as DETACHED. This may solve the
6321 problem observed by some Win95/98 users where they get CGI script
6322 output sent to the console. [Bill Stoddard]
6324 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
6325 routines are now called ap_base64* and are 'plain' (i.e., no
6326 pool access or anything clever). Inside util.c the routines acting
6327 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
6328 The oddly named ap_uuencode(), ap_uudecode() are kept around for
6329 now but deprecated. [dirkx]
6331 *) Clean up the base64 and SHA1 additions and make sure they are
6332 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
6333 files. [Roy Fielding]
6335 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
6336 checking. Allow compiling on VS 6.0. [Randy Terbush]
6338 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
6340 *) Use TestCompile to search for the truerand library (rather than blindly
6341 assuming its existence). If it is not found, complain (but do not
6342 exit - yet). [Martin Kraemer]
6344 *) We forgot to add the new exported function names to
6345 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
6347 *) Add description of -T command-line option to usage().
6348 [Ralf S. Engelschall]
6350 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
6351 searched only AFTER libap has been searched, because libap needs
6352 some symbols from libos. [Martin Kraemer]
6354 *) Fix conflict with original mod_digest related to the symbol of the
6355 module dispatch list (which has to be unique for DSO and follow the
6356 usual conventions for the installation procedure).
6357 [Ralf S. Engelschall]
6359 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6360 for other platforms as well. [Martin Kraemer]
6362 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6363 types by AP_LONG and replace reference to renamed variable 'ubuf'
6364 by 'buffer'. [Martin Kraemer]
6366 Changes with Apache 1.3.8 [not released]
6368 *) Flush the output buffer immediately after sending an error or redirect
6369 response, since the result may be needed by the client to abort a
6370 long data transfer or restart a series of pipelined requests.
6371 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
6373 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6374 [Ian Turner <iant@sequent.com>] PR#4735
6376 *) Local struct mmap in http_core.c conflicted with system structure
6377 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6379 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6380 [Ronald Tschalär <ronald@innovation.ch>]
6382 *) Fix a memory leak where the module counts were getting messed
6383 up across restarts. [David Harris <dharris@drh.net>]
6385 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6386 properly in mod_access.
6387 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
6389 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6390 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
6392 *) PORT: Support for compaq/tandem/com.
6393 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
6395 *) Added SHA1 password encryption support to easy migration from
6396 Netscape servers. See support/SHA1 for more information.
6397 Caused the separation of ap_md5.c into md5, sha1 and a general
6398 ap_checkpass.c with just a validate_passwd routine. Added a
6399 couple of flags to support/htpasswd. Some reuse of the to64()
6400 function; hence renamed to ap_to64().
6401 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
6403 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6404 with ASCII/EBCDIC conversions in "ident" query.
6405 [David McCreedy <McCreedy@us.ibm.com>]
6407 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6408 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6409 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6411 *) Fix SIGSEGV on some systems because the Vary fix below included
6412 a call to table_do with a variable argument list that was not
6413 NULL terminated. Replaced with better implementation. [Roy Fielding]
6415 Changes with Apache 1.3.7 [not released]
6417 *) The "Vary" response header field is now sanitised right before
6418 the header is sent back to the client. Multiple "Vary" fields
6419 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6420 "Vary: host, negotiate, host, accept-language") are reduced to
6421 single instances. This is a better solution than the force-no-vary
6422 one (which is still valid for clients that can't cope with Vary
6423 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6425 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
6427 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6428 least on Linux and FreeBSD for now.
6431 *) Win32: More apache -k restart work. Restarts are now honored
6432 immediately and connections in the listen queue are -not- lost.
6433 This is made possible by the use of the WSADuplicateSocket()
6434 call. The listeners are opened in the parent, duplicated, then
6435 the duplicates are passed to the child. The original listen sockets
6436 are not closed by the parent across a restart, thus the listen queue
6438 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6440 *) Fix handling of case when a client has sent "Expect: 100-continue"
6441 and we are going to respond with an error, but get stuck waiting to
6442 discard the body in the pointless hope of preserving the connection.
6443 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
6445 *) Fix 'configure' to work correctly with SysV-based versions of
6446 'tr' (consistent with Configure's use as well). [Jim Jagielski]
6448 *) apxs: Add "-S var=val" option which allows for override of CFG_*
6449 built-in values. Add "-e" option which works like -i but doesn't
6450 install the DSO; useful for editing httpd.conf with apxs. Fix
6451 editing code so that multiple invocations of apxs -a will not
6452 create duplicate LoadModule/AddModule entries; apxs can now be
6453 used to re- enable/disable a module. [Wilfredo Sanchez]
6455 *) Win32: Update the server to use Winsock 2. Specifically, link with
6456 ws2_32.lib rather than wsock32.lib. This gives us access to
6457 WSADuplcateSocket() in addition to some other enhanced comm APIs.
6458 Win 95 users may need to update their TCP/IP stack to pick up
6459 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
6460 [Bill Stoddard stoddard@raleigh.ibm.com]
6462 *) Win32: Redirect CGI script stderr (script debug info) into the
6463 error.log when CGI scripts fail. This makes Apache on Win32
6464 behave more like Unix.
6465 [Bill Stoddard stoddard@raleigh.ibm.com]
6467 *) Fixed `httpd' usage display: -D was missing.
6468 [Ralf S. Engelschall] PR#4614
6470 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
6471 [Ralf S. Engelschall] PR#4561, PR#4562
6473 *) OS/2: Fix problem with accept lock semaphores where server would die with
6474 "OS2SEM: Error 105 getting accept lock. Exiting!"
6475 [Brian Havard] PR#4505
6477 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
6478 [Randy Terbush <randy@covalent.net>]
6480 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
6481 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
6483 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
6484 command potentially _is_ GCC. [Ralf S. Engelschall]
6486 *) Fix apxs build issues on AIX
6487 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
6489 *) DocumentRoot Checking: Under previous versions, when Apache
6490 first started up, it used to do a stat of each DocumentRoot to
6491 see if it existed and was a directory. If not, then an error
6492 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
6493 does not exist, you will get error messages in error_log. If
6494 the '-t' command line option is used (to check the configuration)
6495 the check of DocumentRoot IS performed. An additional command
6496 line option, '-T', has been added if you want to avoid the
6497 DocumentRoot check even when checking the configuration.
6500 *) Win32: The query switch "apache -S" didn't exit after showing the
6501 vhost settings. That was inconsistent with the other query functions.
6502 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
6504 *) Win32: Changed behaviour of apache -k restart.
6505 Previously, the server would drain all connections in the stack's
6506 listen queue before honoring the restart. On a busy server, this
6507 could take hours. Now, a restart is honored almost immediately.
6508 All connections in Apache's queues are handled but connections in
6509 the stack's listen queue are discarded. Restart triggered by
6510 MaxRequestPerChild is unchanged.
6511 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6513 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
6514 the accept loop. Good for a 5% performance boost. Cleaned up
6515 parent/child process management code.
6516 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6518 *) Added ceiling on file size for memory mapped files.
6519 [John Giannandrea <jg@meer.net>] PR#4122
6521 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
6522 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
6523 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
6525 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
6526 use this at least for Expat. [Ralf S. Engelschall]
6528 *) Allow .module files to specify libraries with Lib:.
6531 *) Allow SetEnvIf[NoCase] to test environment variables as well
6532 as header fields and request attributes. [Ken Coar]
6534 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
6535 content-types are "text/html;parameters". PR#4524 [Ken Coar]
6537 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
6538 never accepted into any standard, and it opens up certain DoS
6539 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
6541 *) TestCompile updated. We can now run programs and output the
6542 results during the Configure process. [ Jim Jagielski]
6544 *) The source is now quad (long long) aware as needed. Specifically,
6545 the Configure process determines the correct size of off_t and
6546 *void. When the OS/platform/compiler supports quads, ap_snprintf()
6547 provides for the 'q' format qualifier (if quads are not available,
6548 'q' is silently "demoted" to long). [Jim Jagielski]
6550 *) When the username or password fed to htpasswd is too long, include the
6551 size limit in the error message. Also report illegal characters
6552 (currently only ':') in the username. Add the size restrictions
6553 to the man page. [Ken Coar]
6555 *) Fixed the configure --without-support option so it doesn't result in
6556 an infinite loop. [Marc Slemko]
6558 *) Piped error logs could cause a segfault if an error occured
6559 during configuration after a restart.
6560 [Aidan Cully <aidan@panix.com>] PR#4456
6562 *) If a "Location" field was stored in r->err_headers_out rather
6563 than r->headers_out, redirect processing wouldn't find it and
6564 the server would core dump on ap_escape_html(NULL). Check both
6565 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
6566 if Location isn't set. [Doug MacEachern, Ken Coar]
6568 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
6569 of the Expat 1.0.2 distribution. [Greg Stein]
6571 *) Replace regexec() calls with calls to a new API stub function
6572 ap_regexec(). This solves problems with DSO modules which use the regex
6573 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
6575 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
6576 environment variables can be set according to the protocol version
6577 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
6579 *) Add DSO support for OpenStep (Mach 4.2) platform.
6580 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
6582 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
6583 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
6585 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
6586 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
6588 *) Better DSO flags recognition on NetBSD platforms using ELF.
6589 [Todd Vierling <tv@pobox.com>] PR#4310
6591 *) Always log months in english format for %t in mod_log_config.
6592 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
6594 *) Support for server-parsed and multiview-determined ReadmeName and
6595 HeaderName files in mod_autoindex. Removed the restriction on
6596 "/"s in ReadmeName and HeaderName directives since the *sub_req*
6597 routines will deal with the access issues. (It's now possible to
6598 have {site|group|project|customer|...} wide readmes and headers.)
6599 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
6602 *) When stat() fails, don't assume anything about the contents of
6603 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
6605 *) It's OK for a semop to return EINTR, just loop around and try
6606 again. [Dean Gaudet]
6608 *) Fix configuration engine re-entrant hangups, which solve a
6609 handful of problems seen with mod_perl <Perl> configuration sections
6610 [Salvador Ortiz Garcia <sog@msg.com.mx>]
6612 *) Mac OS and Mac OS X Server now use the appropriate custom layout
6613 by default when building with APACI; allow for platform-specific
6614 variable defaults in configure. [Wilfredo Sanchez]
6616 *) Do setgid() before initgroups() in http_main; some platforms
6617 zap the grouplist when setgid() is called. This was fixed in
6618 suexec earlier, but the main httpd code missed the change.
6619 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
6621 *) Add recognition of .tgz as a gzipped tarchive.

6624 *) mod_include's fsize/flastmod should allow only relative paths, just
6625 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
6627 *) OS/2: Add support for building loadable modules using DLLs.
6630 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
6633 *) Fix minor but annoying bug with the test for Configuration.tmpl
6634 being newer than Configuration so that it is less likely to fail
6635 when using APACI and shadow sources. [Wilfredo Sanchez]
6637 *) PORT: Add initial support for Mac OS (versions 10.0 and
6638 greater). Use Mac OS X Server layout for now. Clean up dyld code
6639 in unix/os.c, and don't install the dyld error handlers, which
6640 are no longer needed in Mac OS. [Wilfredo Sanchez]
6642 *) Rename Rhapsody layout to "Mac OS X Server". Change install
6643 locations to appropriate ones for user-built (as opposed to
6644 system) installs. [Wilfredo Sanchez]
6646 *) Modify mod_autoindex's handling of AddDescription so that the
6647 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
6649 *) Add functionality to the install-bindist.sh script created by
6650 binbuild.sh to use tar when copying distribution files to the
6651 serverroot. This allows upgrading an existing installation
6652 without nesting the new distribution in the old.
6654 install-bindist.sh now detects the local perl5 path to install
6655 apxs and dbmmanage with proper path to perl interpreter.
6657 Add an install-binsupport target which copies the source files
6658 for apxs and dbmmanage to bindist to allow these scripts to
6659 be properly installed relative to the destination serverroot.

6770 [Peter 'Luna' Altberg <peter@altberg.nu>, Ronald Tschalär]
6772 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
6775 *) Correct an apparent typo: on the Windows and MPE platforms, the
6776 htpasswd utility was limiting passwords to only 8 characters.
6779 *) EBCDIC platforms: David submitted patches for two bugs in the
6780 MD5 digest port for EBCDIC machines:
6781 a) the htdigest utility overwrote the old contents of the digest file
6782 b) the Content-MD5 header value (ContentDigest directive) was wrong
6783 when the returned file was not converted from EBCDIC, but was a
6784 binary (e.g., image file) in the first place.
6785 [David McCreedy <mccreedy@us.ibm.com>]
6787 *) support/htpasswd now permits the password to be specified on the
6788 command line with the '-b' switch. This is useful when passwords
6789 need to be maintained by scripts -- particularly in the Win32
6790 environment. [Ken Coar]
6792 *) Win32: Win32 multiple services patch. Added capability to install and
6793 run multiple copies of apache as individual services.
6796 apache -n apache1 -i -f c:/httpd.conf
6797 Installs apache as service 'apache1' and associates c:/httpd.conf
6800 Starts apache1 service.
6802 Stops apache1 service
6805 apache -n apache2 -i
6806 Installs apache as service 'apache2'. httpd.conf is located under
6807 the default server root (/apache/conf/httpd.conf).
6809 Starts apache2 service.
6812 apache -n apache3 -i -d c:/program files/apache
6813 Install apache as service 'apache3' and sets server root to
6814 c:/program files/apache.

6818 Restart apache2 service
6820 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
6822 *) Correct the signed/unsigned character handling for the MD5 routines;
6823 mismatches were causing compilation problems with gcc -pedantic and
6824 in the TPF cross-compilation. [Ken Coar]
6826 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
6827 a roughly 5 fold speed up. [Brian Havard]
6829 *) proxy ftp: instead of using the hardwired string "text/plain" as
6830 a fallback type for files served by the ftp proxy, use the
6831 ap_default_type() function to determine the configured type.
6832 This allows for special configurations like
6833 <Directory proxy:ftp://some.host>
6834 DefaultType gargle/blurb
6836 Additionally, add the Content-Encoding: header to FTP proxy replies
6837 when the encoding is defined (by the AddEncoding directive).
6838 Because it was missing, it was almost impossible to browse compressed
6839 files using the FTP proxy (works now perfectly in Communicator).
6840 The ftp proxy now also returns the Date: and Server: header lines (if not
6841 much else... This code is "somewhat" broken) like normal requests do.
6844 *) Be more smart in APACI's configure script when determining the UID/GID
6845 for User/Group directives and use the determined UID/GID to initialize
6846 the permissions on the proxycachedir.
6847 [Dirk-Willem van Gulik, Ralf S. Engelschall]
6849 *) Changed the forking-prior-to-cleanup in the proxy module to first
6850 check wether it actually needs to collect garbage. This reduces
6851 the number of fork()s from one/request to just the odd one an hour.
6852 [Dirk-Willem van Gulik]
6854 *) Added proxy, auth and header support to src/support/ab.c. Added a
6855 README file to src/support/
6856 [Dirk-Willem van Gulik]
6858 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.

6861 *) Add support for DSO module compilation on BSD/OS 3.x.
6862 [Randy Terbush, Covalent Technologies]
6864 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
6865 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
6866 option) were substituted with $(TARGET).conf, etc. Same for other strings
6867 with dots where the dot wasn't matched as plain text.

6875 Changes with Apache 1.3.6
6877 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
6879 Changes with Apache 1.3.5 [not released]
6881 *) M_INVALID needed a value within the scope of METHODS so that unknown
6882 methods can be access controlled. [Roy Fielding] PR#3821
6884 *) Added PassAllEnv; makes server's entire environment available
6885 to CGIs and SSIs executed within directive's scope. [Ken Coar]
6887 *) ap_uuencode() always added two trailing '='s and encoding of
6888 8 bit characters on a machine with signed char may produced
6889 incorrect results. Additionally ap_uuencode() should now
6890 work correctly on EBCDIC platforms.
6891 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
6893 *) WIN32: Binary installer now runs the configuration DLL before
6894 the reboot prompt (which is only given if MSVCRT.DLL system
6895 DLL is new or updated). This should avoid the configuration
6896 directory being empty after installation. [Paul Sutton]
6897 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
6899 *) WIN32: Binary installer now creates Start menu options to start
6900 and stop Apache as a console application and to uninstall
6901 the Apache service on NT. [Paul Sutton] PR#3741
6903 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
6905 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
6906 have been reported with flock() locking (probably related to kernel
6907 version). [Dean Gaudet] PR#2723, 3531
6909 *) Using APACI, the main config file (usually httpd.conf) was
6910 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
6911 <wsanchez@apple.com>]
6913 *) PORT: AIX does not require the SHARED_CODE "hack"
6914 [Ryan Bloom <rbb@raleigh.ibm.com>]
6916 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
6917 avoidance code added in 1.3.3.
6918 [Dean Gaudet, Jeff Lewis <lewis@stanford.edu>] PR#3872
6920 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
6921 for 8-bit safeness. [Dean Gaudet]
6923 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
6924 because SPARCs have a small machine-specific maximum size for the Global
6925 Offset Table which is often exceeded when compiling one of the larger
6926 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
6928 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
6929 DSO/DLL section because it's a directive from mod_status and isn't
6930 available before the DLL of mod_status is loaded.
6931 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
6933 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
6934 continuation facility in Apache's configuration files which could
6935 lead to a buffer overflow situation.
6936 [Thomas Devanneaux <Thomas.Devanneaux@enst.fr>] PR#3617
6938 *) Make documentation and error messages of APACI's --activate-module=FILE
6939 option more clear. [Jan Wolter <janc@wwnet.net>] PR#3995

6942 really support all future gcc versions >= 2.7 until we know more.
6943 [John Tobey <jtobey@banta-im.com>] PR#3983
6945 *) Let APACI's configure script correctly complain for unknown --enable-XXX
6946 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
6948 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
6949 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
6950 possible buffer overflows. [Ralf S. Engelschall]
6952 *) Remove no longer used non-API function ap_single_module_init().
6953 [Ralf S. Engelschall]
6955 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
6958 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
6959 to make platform installations easier. [Wilfredo Sanchez]
6961 *) In configure, do not append the target name to the directory path if
6962 the path already contains "apache". [Ralf S. Engelschall]
6964 *) SIGPIPE is now ignored by the server core. The request write routines
6965 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
6966 correctly check for output errors and mark the connection as aborted.
6967 Replaced many direct (unchecked) calls to ap_b* routines with the
6968 analogous ap_r* calls. [Roy Fielding]
6970 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
6971 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
6972 Furthermore map lookups for non-existent keys are now cached as well.
6973 Additionally "txt" maps are now parsed with simple string functions
6974 instead of using ap_pregcomp(). As a side effect a bug that prevented
6975 the usage of keys containing the "," character was fixed.
6976 The changes drastically improve the performance when large rewrite maps
6978 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
6980 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
6981 other than GET, and const'd the definition of method in request_rec.
6984 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
6986 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
6987 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
6989 *) Add %V to mod_log_config, this logs the hostname according to the
6990 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
6991 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
6993 *) Add support for \n and \t to mod_log_config, can be used to produce
6994 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
6996 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
6998 *) Added informative error messages for failed munmap() and fseek() calls
6999 in http_core.c. [John Bley, Roy Fielding]
7001 *) Added some informative error messages for some failed malloc()
7002 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
7004 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
7005 is removed. This allows <Directory proxy:*> directives to work and
7006 prevents invalid requests from killing the process.
7007 [Brian Havard <brianh@kheldar.apana.org.au>]
7009 *) Reorganised FAQ document.
7010 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
7012 *) src/support/: The ApacheBench benchmark program was overhauled by
7013 David N. Welton: you can now have it generate an HTML TABLE, presumably
7014 for integration into other HTML sources. David updated the ab man page
7015 as well and added some missing descriptions. Thanks!
7016 [David N. Welton <davidw@prosa.it>]
7018 *) Win32: The filename validity checker now allows filenames containing
7019 characters in the range 0x80 to 0xff (for example accented characters).
7020 [Paul Sutton] PR#3890
7022 *) Added conditional logging based upon environment variables to
7023 mod_log_config. mod_log_referer and mod_log_agent
7024 are now deprecated. [Ken Coar]
7026 *) Allow apache acting as a proxy server to relay the real
7027 reason of a failure to a client rather than the "internal
7028 server error" it does currently. The general exposure mechanism
7029 can be triggered by any module by setting the "verbose-error-to"
7030 note to "*"; this allows more than just proxy errors to be exposed.
7031 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
7033 *) Moved man pages for ab and apachectrl to section 8.
7034 [Wilfredo Sanchez, Roy Fielding]
7036 *) Added -S option to install.sh so that options can be passed to
7037 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
7039 *) Tweak modules Makefile generated by Configure so that it handles
7040 the test case of no modules being selected. [chaz@reliant.com]
7042 *) Added a <LimitExcept method ...> sectioning directive that allows
7043 the user to assign authentication control to any HTTP method that
7044 is *not* given in the argument list; i.e., the logical negation
7045 of the <Limit> directive. This is particularly useful for controlling
7046 access on methods unknown to the Apache core, but perhaps known by
7047 some module or CGI script. [Roy Fielding, Tony Finch]
7049 *) Prevent apachectl from complaining if the PIDFILE exists but
7050 does not contain a process id, as might occur if the server is
7051 being rapidly restarted. [Wilfredo Sanchez]
7053 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
7055 *) Entity tag comparisons for If-Match and If-None-Match were not being
7056 performed correctly -- weak tags might cause false positives. Also,
7057 strong comparison wasn't properly enforced in all cases.
7058 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
7060 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
7063 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
7064 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
7066 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
7067 to util.c for parsing an HTTP header field value to extract the next
7068 list item, taking into account the possible presence of nested comments,
7069 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
7070 insignificant whitespace and lowercases non-quoted tokens.
7071 [Roy Fielding] PR#2065
7073 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
7074 code different from 500. This allows the proxy to, e.g., return
7075 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
7077 *) Fix ordering of language variants for the case where the traditional
7078 negotiation algorithm is being used with multiple language variants
7079 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
7081 *) Do not round the TCN quality calculation to 5 decimal places,
7082 unlike RFC 2296, because the calculation might need 12 decimal places
7083 to get the right result. [Roy Fielding]
7085 *) Remove unused code to disable transparent negotiation when
7086 negotiating on encoding only, as we now handle encoding too
7087 (though this is nonstandard for TCN), remove charset=ISO-8859-1
7088 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
7089 some debugging statements within mod_negotiation. [Koen Holtman]
7091 *) Fixed a rare memory corruption possibility in mod_dir if the index
7092 file is negotiable and no acceptable variant can be found.
7093 [Dean Gaudet, Roy Fielding, Martin Kraemer]
7095 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
7096 searching the Win32 registry for script interpreters.
7099 *) Win32: The compiled-in default filename for the error log is now
7100 error.log, which matches the default in the distributed httpd.conf.
7103 *) Win32: Any error messages from -i or -u command line options are now
7104 displayed on the console output rather than sent to the error log.
7105 Also the "Running Apache..." message is not output unless Apache is
7106 going to serve requests. [Paul Sutton]
7108 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
7109 and use a private significator ('$apr1$') to mark passwords as
7110 being smashed with our own algorithm. Also abstract the password
7111 checking into a new ap_validate_password() routine. [Ken Coar]
7113 *) Win32: The filename validity checker now allows "COM" but refuses
7114 access to "COM1" through "COM4". This allows filenames such
7115 as "com.name" to be served. [Paul Sutton] PR#3769.
7117 *) BS2000: Adapt to the new ufork() system call interface which will
7118 make subtasking easier on the OSD/POSIX mainframe environment.
7121 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
7122 ap_compat.h. [David White <david@persimmon.com>] PR#3725
7124 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
7125 use `.db' instead of `.pag' not only for FreeBSD, but also when
7126 the NDBM library looks like Berkeley-DB based.
7127 [Ralf S. Engelschall] PR#3773
7129 *) Add ability to handle DES or MD5 authentication passwords.
7130 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
7132 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
7134 *) SECURITY: Avoid some buffer overflow problems when escaping
7135 quoted strings. (This overflow was on the heap and we believe
7136 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
7138 *) Let src/Configure be aware of CFLAGS options starting with plus
7139 signs as it's the case for the HP/UX compiler.
7140 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
7142 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
7143 and check to see if the tar we wind up with supports '-h'.
7144 [Jim Jagielski] PR#3671
7146 *) A consistent and conservative style for all shell scripts has been
7147 implemented. Basically, all shell string tests use the traditional
7148 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
7149 to protect against bare null variable strings (ie: wrapping both
7150 sides with double quotes and prepending 'x'). 'x' was chosen
7151 because it's more universal and hopefully easier for old shell
7152 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
7155 *) The status module now prints out both the main server generation as
7156 well as the generation of each process. Also, the vhost info is
7157 printed with '?notable'. [Jim Jagielski]
7159 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
7160 and this makes its functions available to things in src/support.
7163 Changes with Apache 1.3.4
7165 *) Renamed macros status_drops_connection to ap_status_drops_connection
7166 and vestigial scan_script_header to ap_scan_script_header_err,
7167 mostly for aesthetic reasons. [Roy Fielding]
7169 *) The query switch "httpd -S" didn't exit after showing the
7170 vhost settings. That was inconsistent with the other query functions.
7173 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
7174 filename to the end of the STANDARD_MODULE_STUFF. Its
7175 presence at the beginning prevented reporting of the filename
7176 for modules compiled before 1 January 1999. [Ken Coar]
7178 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
7179 to detect and prevent access to special DOS device file names.
7180 [Paul Sutton, Ken Parzygnat]
7182 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
7183 and Makefile_win32_debug.txt (debug build) that work on Win95.
7184 Run each of the following from the src directory:
7185 nmake /f Makefile_win32.txt # compiles normal build
7186 nmake /f Makefile_win32.txt install # compiles and installs
7187 nmake /f Makefile_win32.txt clean # removes compiled junk
7188 nmake /f Makefile_win32_debug.txt # compiles debug build
7189 nmake /f Makefile_win32_debug.txt install
7190 nmake /f Makefile_win32_debug.txt clean
7193 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
7194 to build binary distributions. [Lars Eilebrecht]
7196 *) IndexOptions SuppressColumnSorting only turned off making
7197 the column headers anchors; you could still change the display
7198 order by manually adding a '?N=A' or similar query string to the
7199 URL. Now SuppressColumnSorting locks in the sort order so
7200 it can't be overridden this way. [Ken Coar]
7202 *) Added IndexOrderDefault directive to supply a default sort order
7203 for FancyIndexed directory listings. [Ken Coar] PR#1699
7205 *) Change the ap_assert macro to a variant that works on all platforms.
7206 [Richard Prinz <richard.prinz@cso.net>] PR#2575
7208 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
7209 search for an underscore on dlsym() (as it's already the case
7210 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
7212 *) Small fix for mod_env.html: The module was documented as to be _not_
7213 compiled into Apache per default, although it _IS_ compiled into
7214 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
7216 *) Instead of fixing a bug in the generation procedure for config.status (a
7217 backslash was missing) we remove the bug together with it's complete
7218 context because the special cases of the past can now no longer occur
7219 because of the recent magic for the --with-layout default.
7220 [Ralf S. Engelschall] PR#3590
7222 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
7223 making sure the src/support/ tools are _forced_ to be build last (they
7224 depend on other libraries).
7225 [Markus Theissinger <markus.theissinger@gmx.de>]
7227 *) Fix installation procedure: Now that os-inline.c is actually used (a
7228 recently fixed bug prevented this) we need to also install os-include.c
7229 in addition to os.h into the PREFIX/include/ location or building of
7230 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
7232 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
7233 allow us to distinguish between a garbled DSO (or even a file which isn't
7234 an Apache module DSO at all) and a DSO which doesn't match the current
7235 Apache API. [Ralf S. Engelschall] PR#3152
7237 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
7238 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
7239 match case insensitive (this especially avoids nasty patterns like
7240 `[tT][eE][sS][tT]'). Second two additional internal map functions
7241 `escape' and `unescape' were added which can be used to escape/unescape
7242 to/from hex-encodings in URLs parts (this is especially useful in
7243 combination with map lookups).
7244 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
7246 *) Renamed the macro escape_uri() to ap_escape_uri() which was
7247 forgotten (because it was a macro) in the symbol renaming process.
7248 [Ralf S. Engelschall]
7250 *) Fix some inconsistencies related to the scopes of directives. The only
7251 user visible change is that the directives `UseCanonicalName' and
7252 `ContentDigest' now use the (more correct) `Options' scope instead of
7253 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
7255 *) Using DSO, the Server token was being mangled. Specifically, the
7256 module's token was being added first before the Apache token. This
7257 has been fixed. [Jim Jagielski]
7259 *) Major overhaul of mod_negotiation.c, part 2.
7260 - properly handle "identity" within Accept-Encoding.
7261 - allow encoded variants in RVSA negotiation and let them appear in
7262 the Alternates field using the non-standard "encoding" tag-list.
7263 - fixed both negotiation algorithms so that an explicitly accepted
7264 encoding is preferred over no encoding if "identity" is not
7265 included within Accept-Encoding.
7266 - added ap_array_pstrcat() to alloc.c for efficient concatenation
7267 of large substring sequences.
7268 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
7271 *) Major overhaul of mod_negotiation.c, part 1.
7272 - cleanups to mod_negotiation comments and code structure
7273 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
7274 support for everything in the upcoming HTTP/1.1
7275 revision (draft-ietf-http-v11-spec-rev-06.txt).
7276 - language tag matching also handles tags with more than 2
7278 - empty Accept, Accept-Language, Accept-Charset headers are
7279 processed correctly; previously an empty header would make all
7280 values acceptable instead of unacceptable.
7281 - allowed for q values in Accept-Encoding
7282 - added support for transparent content negotiation (rfc2295 and
7283 rfc2296) (though we do not implement all features in these drafts,
7284 e.g. no feature negotiation). Removed old experimental version.
7285 - implemented 'structured entity tags' for better cache correctness
7286 (structured entity tags ensure that caches which can deal with Vary
7287 will (eventually) be updated if the set of variants on the server
7289 - this involved adding a vlist_validator element to request_rec
7290 - this involved adding the ap_make_etag() function to the global API
7291 - modified guessing of charsets used by Apache negotiation algorithm
7292 to guess 'no charset' if the variant is not a text/* type
7293 - added code to sort multiviews variants into a canonical order so that
7294 negotiation results are consistent across backup/restores and mirrors
7295 - removed possibility of a type map file resolving to another type map
7296 file as its best variant

7323 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
7326 *) Update APXS manual page: some -q option arguments were missing
7327 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
7329 *) Cleanup the command line options: `-?' was documented to show
7330 the usage list but does it with an error because `?' is not a valid
7331 command. OTOH a lot of users expect `-h' to print such a usage list and
7332 instead are annoyed for ages by our huge unreadable list of directives.
7333 So we now changed the command line options this way:
7335 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
7336 very similar to the popular linker option.
7338 Intent: while -l gives the small list of modules, -L now gives the
7339 large list of directives implemented by these modules. This is also
7340 consistent with -v (short version info) and -V (large version info).
7342 Intent: it's now the expected option ;-)
7343 The manual page was adjusted accordingly.

7347 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
7349 *) Removed recently introduced bugs and disfigurements in APACI:
7350 o fixed argument line processing: using $args was broken: It was not
7351 initialized and using args="$args $apc_option" and even args="$args
7352 \"$apc_option\"" fails in the second processing round for any arguments
7353 containing whitespaces. The only correct way is to use the construct
7354 "$@" (but not possible here) or iterate _both_ times over the implicit
7355 argument line (no argument to for-loop) which is what we now use.
7356 o make --with-layout=Apache the default without creating
7357 redundancy (copying the --with-layout block in the argument parsing
7358 loop). We achieve this by using the "$@" construct together with the
7359 `set' command to prepend --with-layout=Apache to the command line in
7360 case --with-layout is not used.
7361 o fixed auto-suffix handling now that config.layout exists.
7362 Paths which are auto-suffixed are marked with a trailing plus sign in
7363 config.layout and every path now can be marked this way (not only the
7364 four paths for which we do it currently). Additionally the suffix is
7365 no longer a static one. Instead it's now `/<target>' where <target> is
7366 the argument of the --target option or per default `httpd'.
7367 o allow also tabs (and only spaces) where we match whitespaces
7368 o various fixes and cleanups related to used shell coding style
7369 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7370 o trimmed output of --help to fit into 80 columns

7437 identifier, currently "Apache" and "GNU" are pre-defined in the file
7438 config.layout. Custom layouts are possible by using FILE:ID as the
7439 argument where the layout ID is taken from FILE.
7441 The config.layout file consists of <Layout ID>..</Layout> sections
7442 where inside those sections "path_variable: path_value" pairs can be
7443 specified. These lines are converted to path_variable='path_value'.
7445 *) Add a DefaultLanguage directive so that files missing a language
7446 extension (e.g., .fr, .de) can be labelled as being some other

7730 *) Reconstructed the loop through multiple htaccess file names so
7731 that missing files are not confused with unreadable files.
7734 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
7735 errno on an error, which leads to one error being mistaken for
7736 another when reading non-existent .htaccess files.
7739 *) OS/2: The new header tests get things right, need to update
7740 ap_config.h. [Brian Havard]

7757 Changes with Apache 1.3.2
7759 *) Fix bug in ap_remove_module(), which caused problems for dso's
7760 who were the top_module. [Doug MacEachern]
7762 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
7763 mod_auth_db to both be friendly to users who wants to use this version
7764 and to avoid problems under platforms where only version 2.x is present.
7765 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
7767 *) When using ap_log_rerror(), make the error message available to the
7768 *ERROR_NOTES envariables by default. [Ken Coar]
7770 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
7771 You now must define a BS2000Account name for the server User.
7772 This has fewer security implications than the old approach.
7775 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
7776 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
7777 platform to make the braindead HPUX linker happy. Notice, for the module
7778 DSOs we don't have to use this, because these are loaded manually (and
7779 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
7781 *) Remove 64 thread limit on Win32.

7788 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
7790 *) Make PrintPath work generically instead of having one version
7791 strictly for OS/2. [Jim Jagielski, Brian Havard]
7793 *) Fix the recently introduced C header file checking: We now use the C
7794 pre-processor pass only (and no longer the complete compiler pass) to
7795 determine whether a C header file exists or not. Because only this way
7796 we're safe against inter-header dependencies (which caused horrible
7797 portability problems). The only drawback is that we now have a CPP
7798 configuration variable which has to be determined first (we do a similar
7799 approach as GNU Autoconf does here). When all fails the user still has
7800 the possibility to override it manually via APACI or src/Configuration.
7801 As a fallback for the header check itself we can directly check the
7802 existance of the file under /usr/include, too.
7803 [Ralf S. Engelschall] PR#2777
7805 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
7806 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
7807 ap_private_extern defined to hide symbols that conflict with loaded
7808 dynamic libraries on the NEXT and RHAPSODY platforms.

7833 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
7834 platform, because it's only supported under version 4.0 and higher. But
7835 because our GuessOS is still unaware of Digital UNIX versions and the
7836 -msym is just to optimize the DSO statup time a little bit it's safe and
7837 best when we leave it out now. [Ralf S. Engelschall] PR#2969
7839 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
7840 functions: First all three functions no longer fail on strings containing
7841 "%" chars and second ap_log_printf() no longer does a double-formatting
7842 (instead it directly passes through the message to be formatted to the
7843 real internal formatting function). [Ralf S. Engelschall] PR#2941
7845 *) Allow "Include" directives anywhere in the server config
7846 files (but not .htaccess files). [Ken Coar] PR#2727
7848 *) The proxy was refusing to serve CONNECT requests except to
7849 port 443 (https://) and 563 (snews://). The new AllowCONNECT
7850 directive allows the configuration of the ports to which a
7851 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
7853 *) mod_expires will now act on content that is not sent from a file
7854 on disk. Previously it would never add an Expires: header to
7855 any response that did not come from a file on disk; the only
7856 case where it still doesn't (and can't) add one for that type of
7857 content is if you are using a modification date based setting.
7858 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
7860 *) Problems encountered during .htaccess parsing or CGI execution
7861 that lead to a "500 Server Error" condition now provide explanatory
7862 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
7865 *) Add NameWidth keyword to IndexOptions directive so that the
7866 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
7869 *) Recognize lowercase _and_ uppercase `uname' results under
7870 SCO OpenServer. [David Coelho <drc@ppt.com>]
7872 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
7873 a common problem of (mis-administrated?) IIS servers, make the apache
7874 proxy immune to these errors (and ignore the duplicates, but log
7875 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
7877 *) The <IfModule and <IfDefine block starting directives now only
7878 allow exactly one argument. Previously, the optional negation
7879 character '!' could be separated by whitespace without a syntax
7880 error being reported, albeit defeating the IfModule functionality
7881 (enclosed directives would ALWAYS be executed). By using the
7882 stricter syntax, these hard-to-track errors can be avoided.
7885 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
7886 cause the standalone FancyIndexing directive to logically OR
7887 into any existing IndexOptions settings rather than wiping
7888 them out. [Ken Coar]
7890 *) Changes in ftp proxy: make URL parsing simpler by using the
7892 + Add display of the "current directory" in cases where it's
7893 different from the supplied path (e.g., ftp://user@host/ lives
7894 in /home/user, not in /, therefore clicking on "../" in the
7895 starting directory might send us to /home/).
7896 + When ftp login fails, (esp. when a user name was part of the
7897 URL already), we now return [401 Unauthorized ] to allow the
7898 browser to pop up an authorization dialog. This makes passwords
7899 slightly less visible (they don't appear in the regular log files)
7900 and implements a functionality that other www proxy servers
7904 *) Triggered by the recent "Via:" header changes, the proxy module would
7905 dump core for replies with invalid headers (e.g., duplicate
7906 "HTTP/1.0 200 OK" lines). These errors are now logged and the
7907 core dump is avoided. Also, broken replies are not cached.
7908 [Martin Kraemer] PR#2914
7910 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
7911 plop gmon.out profile data for each child [Doug MacEachern]
7913 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
7914 config.status script to be immune against arguments with whitespaces.
7915 [Yves Arrouye <yves@apple.com>] PR#2866
7917 *) Replace the inlined information grabbing stuff for the configuration
7918 adjustment feature (no --without-confadjust) with calls to a new helper
7919 script `buildinfo.sh' which is both more flexible and already proofed to
7920 be more robust against platform differences. This mainly fixes the
7921 recently occured ``sed: command garbled: ...'' problems.
7922 [Ralf S. Engelschall] PR#2776, PR#2848
7924 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
7925 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
7926 without complains after we recently added the POST feature.
7927 [Ralf S. Engelschall]
7929 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
7930 modules as API functions and we forgot them at the big symbol renaming.
7931 [Ralf S. Engelschall]
7933 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
7934 [Youichirou Koga <y-koga@jp.FreeBSD.ORG>] PR#2895
7936 *) Dynamically size the filename column of mod_autoindex output.
7939 *) Add the ability to do POST requests to the ab benchmarking tool.
7940 [Kurt Sussman <kls@best.com>] PR#2871
7942 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
7943 5 to 10 because there are some users out there who always have 5 to 8
7944 variables in one RewriteRule and had to patch mod_rewrite.h for every
7945 release. So 15 should be now more than enough, even for them. (I never
7946 needed more than 4 in my RewriteRules ;-)
7947 [Ralf S. Engelschall]
7949 *) Make the proxy generate and understand Via: headers
7952 *) Change the proxy to use tables instead of array_headers for
7953 the header lines. [Martin Kraemer]
7955 *) Make sure the config.status file is not overridden when just
7956 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
7958 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
7959 provide a way to trace API changes that add functionality but do
7960 not create a compatibility issue for precompiled modules, etc.
7961 See include/ap_mmn.h for more details. [Randy Terbush]
7963 *) Fix suexec installation under `make install root=xxx' situation.
7964 [Ralf S. Engelschall]
7966 *) Extend the output of the -V switch to include the paths of all
7967 compiled-in configuration files, if they were overridden at
7968 compile time, for least astonishment of the user.
7971 *) When READing a request in ExtendedStatus mode, the "old"
7972 vhost, request and client information is not displayed.
7975 *) STATUS is no longer available. Full status information now
7976 run-time configurable using the ExtendedStatus directive.
7979 *) SECURITY [CAN-1999-1199] (cve.mitre.org):
7980 Eliminate O(n^2) space DoS attacks (and other O(n^2)
7981 cpu time attacks) in header parsing. Add ap_overlap_tables(),
7982 a function which can be used to perform bulk update operations
7983 on tables in a more efficient manner.
7986 *) SECURITY: Added compile-time and configurable limits for
7987 various aspects of reading a client request to avoid some simple
7988 denial of service attacks, including limits on maximum request-line
7989 size (LimitRequestLine), number of header fields (LimitRequestFields),
7990 and size of any one header field (LimitRequestFieldsize). Also added
7991 a configurable directive LimitRequestBody for limiting the size of the
7992 request message body. [Roy Fielding]
7994 *) Make status module aware of DNS and logging states, even if
7995 STATUS not defined. [Jim Jagielski]
7997 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
7999 *) Enhance mod_speling so that CheckSpelling can be used in
8000 <Directory> containers and .htaccess files. [Ken Coar]
8002 *) API: new ap_custom_response() function for hooking into the
8003 ErrorDocument mechanism at runtime [Doug MacEachern]
8005 *) API: new ap_uuencode() function [Doug MacEachern]
8007 *) API: scan_script_header_err_core() now "public" and renamed
8008 ap_scan_script_header_err_core() [Doug MacEachern]
8010 *) The 'status' module will now show the process pid's and their
8011 state even without full STATUS accounting. [Jim Jagielski]
8013 *) Restore the client IP address to the error log messages, this
8014 was lost during the transition from 1.2 to 1.3. Add a new
8015 function ap_log_rerror() which takes a request_rec * and
8016 formats it appropriately. [Dean Gaudet] PR#2661
8018 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
8019 whitespace in input lines -- including within quoted strings.
8021 but leading and trailing whitespace should continue to be
8022 stripped [Martin Kraemer]
8024 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
8025 the ugly use of an env. variable and use command-line args for
8026 alternate $PATH. Make more like advanced 'type's as well.
8029 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
8030 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
8031 <alain.st-denis@ec.gc.ca>] PR#2736
8033 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
8035 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
8036 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
8037 directory was renamed to src/os/os2/ for consistency.
8038 [Brian Havard, Ralf S. Engelschall]
8040 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
8041 files (here modules) against other DSO files (here shared libraries).
8042 This is done by determining a subset of LIBS which can be safely used for
8043 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
8044 disabled for all platforms to avoid problems with this (experimental)
8045 rule. But we provide it now for those people how ran into problems and
8046 want to came out by forcing linking against DSOs.
8047 [Ralf S. Engelschall] PR#2587
8049 *) Fix suEXEC start message: Has to be of `notice' level to really get
8050 printed together with the standard startup message because the `notice'
8051 level is handled special inside ap_log_error() for startup messages.
8052 [Ralf S. Engelschall] PR#2761 PR#2761 PR#2765
8054 *) Add correct `model' MIME types from RFC2077 to mime.types file.

8057 *) Fixed examples in mod_rewrite.html document.
8058 [Youichirou Koga <y-koga@jp.FreeBSD.org>, Ralf S. Engelschall] PR#2756
8060 *) Allow ap_read_request errors to propagate through the normal request
8061 handling loop so that the connection can be properly closed with
8062 lingering_close, thus avoiding a potential TCP reset that would
8063 cause the client to miss the HTTP error response. [Roy Fielding]
8065 *) One more portability fix for APACI shadow tree support: Swap order of awk
8066 and sed in top-level configure script to avoid sed fails on some
8067 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
8068 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729

8076 structure instead of just NULL. This fixes at least the RewriteMap
8077 programs under Win32. [Marco De Michele <mdemichele@tin.it>] PR#2483

8090 *) Fix `install-includes' sub-target of `install' target in top-level
8091 Makefile.tmpl: The umask+cp approach didn't work as expected (especially
8092 for users which extracted the distribution under 'umask 077'), so replace
8093 it by an explicit cp+chmod approach.
8094 [Richard Lloyd, Curt Sampson, Ralf S. Engelschall] PR#2656 PR#2626

8098 [Ralf S. Engelschall]
8100 *) Use a more straight forward and thus less problematic Sed command in

8121 situations to prevent pollution of system locations with Apache files.
8122 [Ralf S. Engelschall] PR#2660
8124 *) Fixed problem with buffered response message not being sent for
8125 the read_request error conditions of URI-too-long (414) and
8126 malformed header fields (400). [Roy Fielding] PR#2646
8128 *) Add support for the Max-Forwards: header line required by RFC2068 for
8129 the TRACE method. This allows apache to TRACE along a chain of proxies
8130 up to a predetermined depth. [Martin Kraemer]
8132 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled
8133 (compilers complained) and the .so.V.R.P filename extension was adjusted
8134 to correctly reflect the 1.3.2 version.

8172 *) Global renaming of C header files to both get rid of conflicts with third
8173 party packages and to again reach consistency:
8174 1. conf.h -> ap_config.h
8175 2. conf_auto.h -> ap_config_auto.h \ these are now merged

8178 5. apctype.h -> ap_ctype.h
8179 Backward compatibility files for conf.h and compat.h were created.
8181 *) mod_mmap_static will no longer take action on requests unless at
8182 least one "mmapfile" directive is present in the configuration.
8183 This experimental module has to do some black magic to operate
8184 inside the current API and thus creates side-effects for other

8242 *) The APACI libexecdir was not extended with an "apache/" subdir
8243 if the installation prefix didn't already contain "apache", but
8244 it should be because the DSO files are Apache-specific. Now
8245 libexecdir is treated the same way sysconfdir, datadir, localstatedir
8246 and includedir are already treated.

8271 *) Move the initial suEXEC-related startup message from plain
8272 fprintf()/stderr to a delayed ap_log_error()-based one to avoid problems
8273 when Apache is started from inetd (instead of standalone). Under this

8299 directory, bail out of the request with an error message. [W G Stoddard]
8301 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
8302 these are treated by Win32 as if they are ".." but are not detected by
8303 other machinery within Apache. This is something of a kludge but
8304 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
8306 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
8307 pools and thus pollutes libap (until the pool stuff is moved there).
8310 *) IndexIgnore should be case-blind on Win32 (and any other case-aware

8321 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
8322 remove some of the classical hurdles for new users when setting up
8323 Apache. This is done per default because it is useful for the average
8324 user. Package authors can use the --without-confadjust option to disable
8325 these configuration adjustments.
8326 [Ralf S. Engelschall]
8328 *) Added an EXTRA_DEPS configuration parameter which can be used
8329 to add an extra Makefile dependency for the httpd target, for instance
8330 to external third-party libraries, etc.
8331 [Ralf S. Engelschall]
8333 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
8334 as <IfModule>..</IfModule> sections) which can be used to skip or process
8335 contained commands dependend of ``-D PARAMETER'' options on the command
8336 line. This can be used to achieve logical conditions like <IfDefine
8337 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
8338 and thus especially can be used for conditionally loading DSO-based
8339 modules via LoadModule, etc. [Ralf S. Engelschall]

8346 truncated which forced following HTTP headers to be data in the HTTP
8347 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
8350 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
8351 in top-level configure script to avoid sed fails on some platforms (for
8352 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
8353 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
8355 *) Improve performance of directory listings (mod_autoindex) by comparing
8356 integer keys (last-modified and size) as integers rather than converting
8357 them to strings first. Also use a set of explicit byte tests rather
8358 than strcmp() to check for parent directory-ness of an entry. Oh, and
8359 make sure the parent directory (if displayed) is *always* listed first
8360 regardless of the sort key. Overall performance winnage should be good
8361 in CPU time, instruction cache, and memory usage, particularly for large
8362 directories. [Ken Coar]
8364 *) Add a tiny but useful goody to APACI's configure script: The generation
8365 of a config.status script (as GNU Autoconf does) which remembers the used
8366 configure command and hence can be used to restore the configuration by
8367 just re-running this script or for remembering the configuration between
8369 [Ralf S. Engelschall]
8371 *) Add httpd -t (test) option for running configuration syntax tests only.
8372 If something is broken it complains and exits with a return code
8373 non-equal to 0. This can be used manually by the user to check the Apache
8374 configuration after editing and is also automatically used by apachectl
8375 on (graceful) restart command to make sure Apache doesn't die on restarts
8376 because of a configuration which is now broken since the last (re)start.
8377 This way `apachectl restart' can be used inside cronjobs without having
8378 to expect Apache to be falling down. Additionally the httpd -t can be run
8379 via `apachectl configtest'.

8518 ap_spawn_child_err_buff became ap_bspawn_child
8519 spawn_child was obsoleted and moved to compat.h
8522 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
8523 programs: ap_spawn_child_err() is used and the Win32 case now uses
8524 CreateProcess() instead of a low-level execl() (which caused problems in
8525 the past under Win32).
8526 [Ralf S. Engelschall]
8528 *) A few cosmetics and trivial enhancements to APXS to make the
8529 generated Makefile more user friendly. [Ralf S. Engelschall]
8531 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
8532 was updated to use the normal apache error processing, thereby allowing
8533 proxy errors to be treated by ErrorDocument's as well. For this
8534 purpose, a new module-to-core communication variable "error-notes"
8535 was introduced; the proxy (and possibly other modules) communicates
8536 its error text using this variable. Its content is copied to a new
8537 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
8538 The old proxy special error routine ap_proxy_log_uerror()
8539 was replaced by regular ap_log_error() calls, many messages were made
8541 [Martin Kraemer] PR#494, 1259
8543 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
8546 *) Transform the configure message "You need root privileges for suEXEC"
8547 from a fatal error into a (more friendly) warning because the building
8548 ("make") of Apache we can allow, of course. Root privileges are needed
8549 only for the installation step ("make install"). So make sure the
8550 user is aware of this fact but let him proceed as long as he can.

8611 instead of C file descriptors.
8612 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
8614 *) The proxy cache would store an incorrect content-length in the cached
8615 file copy after a cache update. That resulted in repeated fetching
8616 of the original copy instead of using the cached copy.
8617 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
8619 *) The Makefiles assumed that DSO files are build via $(LD). This
8620 is broken for two reasons: First we never defined at least LD=ld
8621 somewhere to make sure this works (it was silently assumed that most Make
8622 provide a built-in LD definition - ARGL!) and second using the generic LD
8623 variable is not the truth. Instead a special variable named LD_SHLIB is
8624 reasonable because although "ld" is usually the default, the command for
8625 building DSO files can be "libtool" or even "cc" on some systems.
8626 [Ralf S. Engelschall]
8628 *) Replace the AddVersionPlatform directive with ServerTokens which
8629 provides for more control over the format of the Server:
8630 header line. SERVER_SUBVERSION is no longer supported;
8631 all module should use the ap_add_version_component()
8632 API function instead. [Jim Jagielski]

8638 not retrieved in src/Configure and thus was not useable.
8639 [Ralf S. Engelschall]
8641 *) Various Makefile consistency cleanups:
8642 - make OSDIR also automatically be relative to src/ like INCDIR
8643 - SUBDIRS is now generated in src/Makefile only and not in
8644 Makefile.config because it is a local define for this location.
8645 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
8646 any Makefile but make sure that at least the "-K inline" is kept in
8648 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
8649 - updated the dependencies theirself
8650 - removed not existing SHLIB variable from "clean" targets
8651 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
8652 already exists and OBJS_PIC are also just plain objects and have not
8653 directly to do with "shared" things. The only difference is that they
8654 contain PIC. So OBJS_PIC is the more canonical name.
8655 - Updated the Makefile-dependency lines for OBJS_PIC
8656 - Removed the Makefile-dependency line in Configure to avoid double
8658 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
8659 of xxx.lo as GNU libtool does with its PIC objects
8660 - reduce local complexity in modules Makefile.tmpl by moving the last
8661 existing target "depend" to the generation section in Configure, too.
8662 - removed the historical $(SPACER) which was used in the past together
8663 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
8664 is no longer needed.
8665 - force the build and run of the gen_xxx programs under main/ as the
8666 first step before building the objects because it looks cleaner
8667 [Ralf S. Engelschall]
8669 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
8672 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
8675 *) WIN32: Don't force ISAPI headers to finish with \n.
8676 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
8678 *) When opening "configuration" files (like httpd.conf, htaccess
8679 and htpasswd), Apache will not allow them to be non-/dev/null
8680 device files. This closes a DoS hole. At the same time,
8681 we use ap_pfopen to open these files to handle timeouts.
8682 [Jim Jagielski, Martin Kraemer]
8684 *) Apache will now log the reason its httpd children exit if they exit
8685 due to an unexpected signal. (It requires a new porting define,
8686 SYS_SIGLIST, which if defined should point to a list of text
8687 descriptions of the signals available. See PORTING.) [Dean Gaudet]
8689 *) WIN32: chdir() doesn't make sense in a multithreaded environment
8690 like WIN32. Before, Win32 CGI's could have had sporadic failures
8691 if a chdir call from one thread was made between another chdir call
8692 and a spawn in another thread. So, for now don't chdir for CGI scripts
8693 in WIN32. The current CGI "spec" is unclear as to whether it's
8694 necessary. Long-term fix is to either serialize the chdir/spawn combo
8695 or use WIN32 native calls to spawn a process. This temp fix was
8696 necessary to remove this as a showstopper for 1.3's release.
8699 *) Cleanup the suEXEC support in APACI and make it more safe:
8700 1. Add big fat hint in INSTALL about risks and to read the
8701 htdocs/manual/suexec.html document before using the suexec-related
8703 2. Make sure the user has at least provided one --suexec-xxxx option
8704 (specifies suEXEC parameters) in addition to --enable-suexec option.
8705 If only --enable-suexec is given APACI stops with a hint to INSTALL
8706 and htdocs/manual/suexec.html documents.
8707 3. Provide two additional --suexec-xxxx options to make the suEXEC
8708 configuration complete (especially for package maintainers who else
8709 had to patch the source tree) by providing ways to configure minimal
8710 UID/GID and safe PATH, too.
8711 [Ralf S. Engelschall]
8713 *) Cleanup of the `configure --shadow' process:
8714 - make sure the configure script creates its temporary files in the
8715 shadow tree to avoid conflicts with parallel configure runs
8716 - removed unnecessary option "-r" from "rm" call for Makefiles
8717 - make sure the configure scripts creates the shadow-wrapper Makefile
8718 only when no shadow trees already exists
8719 - make sure "make distclean" removes the shadow-wrapper Makefile but only
8720 when no more shadow trees exists
8721 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
8722 as fast (in the past it needed 70sec, now it runs just 38sec)
8723 - make sure CVS does not complain about the created files
8724 Makefille.<gnutriple> and directories src.<gnutriple>
8725 [Ralf S. Engelschall]
8727 *) Added the ap_add_version_component() API routine and the
8728 AddVersionPlatform core directive. The first allows modules to
8729 declare themselves in the Server response header field value,
8730 augmenting the SERVER_SUBVERSION define in the Configuration file
8731 with run-time settings (more useful in a loadable-module environment).
8732 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
8733 into the server version string. [Ken Coar] PR#2056
8735 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
8738 *) Emit the "Accept-Range" header for the default handler.
8739 [Brian Behlendorf] PR#1464
8741 *) Add a note to httpd.conf-dist that apache will on some systems fail
8742 to start when the Group # is set to a negative or large positive value.
8745 *) Make sure the module execution order is correct even when some modules
8746 are loaded under runtime (`LoadModule') via the DSO mechanism:
8747 1. The list of loaded modules is now a dynamically allocated one
8748 and not the original statically list from modules.c
8749 2. The loaded modules are now correctly setup by LoadModule for
8750 later use by the AddModule command.
8751 3. When the DSO mechanism for modules is used APACI's `install'
8752 target now enables all created `LoadModule' lines per default because
8753 this is both already expected by the user _and_ needed to avoid
8754 confusion with the next point and reduces the Makefile.tmpl complexity
8755 4. When the DSO mechanism for modules is used, APACI's `install'
8756 target now additionally makes sure the module list is reconstructed
8757 via a complete `ClearModuleList+AddModule...' entry.
8758 5. The support tool `apxs' now also makes sure an AddModule command
8759 is added in addition to the LoadModule command.
8760 6. The modules.c generation was extended to now contain two
8761 comments to make sure no one is confused by the confusing terminology
8762 of loading/linking (we use load=link+load & link=activate instead of
8763 the obvious load=activate & link=link :-( )
8764 This way now there is no longer a difference under execution time between
8765 statically and dynamically linked modules.

8768 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
8769 Big Symbol Renaming. [Ralf S. Engelschall]
8771 *) Add a comment to mod_example.c showing the format of a FLAG command
8774 *) Standardized the time format in mod_status to match that of other
8775 places in the code (e.g. DATE_GMT). PR#1551
8777 *) Fix handling of %Z in timefmt strings for those platforms with no time
8778 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
8781 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
8782 feature compatible with 'UseCanonicalName off' by changing
8783 r->server->server_hostname to ap_get_server_name(). And I changed some
8784 functions which use r->server->port to use ap_get_server_port() instead,
8785 because if there's no Port directive in the config r->server->port is 0.
8788 *) get/set_module_config are trivial enough to be better off inline. Worth
8789 1.5% performance boost. [Dean Gaudet]
8791 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
8792 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
8795 *) [BS2000 security] BS2000 needs an extra authentication to initialize
8796 the task environment to the unprivileged User id. Otherwise CGI scripts
8797 would have a way to gain super user access. [Martin Kraemer]
8799 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
8800 absolute path, only log base name of logging source as is done
8801 in unix. [Martin Kraemer]
8803 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
8804 the encoding type from the Accept-Encoding header (if it's there)
8805 and use it in the response, as that's probably what it'll be expecting.
8806 [Ronald.Tschalaer@psi.ch]
8808 *) Fix to mod_alias: translate_alias_redir is dealing with
8809 a URI, not a filename, so the check for drive letters for win32

8818 *) Child processes can now "signal" (by exiting with a status
8819 of APEXIT_CHILDFATAL) the parent process to abort and
8820 shutdown the server if the error in the child process was
8821 fatal enough. [Jim Jagielski]

8824 [Jim Jagielski] PR#2112
8826 *) Make sure the referer_log and agent_log entries in the default httpd.conf

8830 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
8832 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
8835 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
8836 Additionally the checks for finding the vendor DSO library were moved
8837 from mod_so.c to Configure because first it needs $PLAT etc. and second
8838 mod_so already uses an abstraction layer and does not fiddle with the
8839 vendor functions itself.
8840 [Jens-Uwe Mager, Ralf S. Engelschall]
8842 *) PORT: Some optimization defines for NetBSD
8843 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
8845 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
8846 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
8848 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
8849 AIX variants should work fine, too. Even AIX 3.x should work). This is
8850 accomplished by using the free DSO emulation code from Jens-Uwe Mager
8851 which we put into a os/unix/os-dso-aix.c file.
8852 [Ralf S. Engelschall]
8854 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
8855 that we should use NET_SIZE_T == int but the include files force size_t.
8856 [Ralf S. Engelschall]
8858 *) Fix two bugs in select() handling in http_main.c.
8861 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
8862 is unset (as it is in situations like timeouts) where it is unclear
8863 whether errno is set or not. [Martin Kraemer]
8865 *) Just having APACI's localstatedir is too general and not enough for most
8866 of the systems. 1.3b6 again required manual APACI patches by package
8867 maintainers from Red Hat and FreeBSD because for their filesystem layout a
8868 little bit more flexibility in configuring the paths is needed. Hence we
8869 provide three additional configure options (--runtimedir, --logfiledir,
8870 --proxycachedir) which now can be used for more granular adjustments if
8871 --localstatedir is not enough to fit the particular needs. As a nice
8872 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
8873 [Ralf S. Engelschall]
8875 *) Make the install root for "make install" in APACI's Makefile overrideable
8876 by package authors. This way we are even more friendly to package
8877 maintainers (especially Debian and Red Hat) who build for the real prefix
8878 via "configure --prefix=/<real>" but use a different local prefix via
8879 "make root=/tmp/apache install" for rolling the package without bristling
8880 the target location on their system.
8881 [Ralf S. Engelschall]
8883 *) Workaround sed limitations in APACI's configure script by now
8884 substituting in chunks of 50 commands (because for instance HPUX's vendor
8885 sed has a limit of max. 98 commands)

8894 [Ralf S. Engelschall]
8896 *) Workaround braindead AWK's when generating ap_config.h: The split() and
8897 substr() functions cannot be nested under vendor AWK from Solaris 2.6.

8901 o fix IFS handling for _nested_ situation
8902 o fix Perl interpreter search: take first one found instead of last one
8903 o fix DSO consistency check
8904 o print error messages to stderr instead of stdout
8905 o add install-quiet for --shadow situation to Makefile stub

8911 *) Make sure the input field separator (IFS) shell variable is explicitly
8912 initialized correctly before _every_ `for' loop and also restored after
8913 the loops. [Ralf S. Engelschall]
8915 *) Make sure that "make install" doesn't overwrite the `mime.types' and
8916 `magic' files from an existing Apache installation. Because people often
8917 customize these for own MIME and content types.

8957 *) If you start apache with the -S command line option it will dump

8959 to figure out what is wrong with their vhost configuration.
8960 (Other dumps may be added in the future.) [Dean Gaudet]
8962 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
8963 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
8966 *) Because /usr/local/apache is the default prefix the ``configure
8967 --compat'' option no longer has to set prefix, again. This way the
8968 --compat option honors a leading --prefix option. [Lars Eilebrecht]
8970 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
8971 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
8972 to avoid "discard const" warnings. [Ralf S. Engelschall]
8974 *) If a specific handler is set for a file yet the request still
8975 ends up being handled by the default handler, log an error
8976 message before handling it. This catches things such as trying
8977 to use SSIs without mod_include enabled. [Marc Slemko]
8979 *) Fix error logging for the startup case where ap_log_error() still uses
8980 stderr as the target. Now the default log level is honored here, too.

8988 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
8990 Changes with Apache 1.3b6
8992 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
8994 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
8995 interface via the similar but proprietary HP/UX shl_xxx-style system
8996 calls. [Ralf S. Engelschall]
8998 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
8999 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
9000 Make. [Ralf S. Engelschall]
9002 *) ++++ THE BIG SYMBOL RENAMING ++++
9003 To avoid symbol clashes with third-party code compiled into the server,
9004 we globally applied the prefix "ap_" to the following classes of
9006 - Apache provided general functions (e.g., ap_cpystrn)
9007 - Public API functions (e.g., palloc, bgets)
9008 - Private functions which we can't make static (because of
9009 cross-object usage) but should be (e.g., new_connection)
9010 For backward source compatibility a new header file named compat.h was
9011 created which provides defines for the old symbol names and can be used
9012 by third-party module authors.
9015 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
9016 problem under SVR4 is that there is no command flag to force the linker
9017 to export the global symbols of the httpd executable therewith they are
9018 available to the DSO's. Instead of problematic hacks like creating a
9019 dummy.so file (containing dummy references to all global symbols) the
9020 httpd binary is linked against, we use a clean trick stolen from Perl 5:
9021 Placing the Apache core code itself into a DSO library named libhttpd.so.
9022 This way the global symbols _HAVE_ to be exported and thus are available
9023 to any manually loaded DSO's under runtime. To reduce the impact to the
9024 user to null we go even further and create a stub httpd executable which
9025 automatically keeps track of the DSO library loading itself and thus
9026 hides the complete mechanism from the user. Although the generation of
9027 this DSO library is automatically triggered for platforms which
9028 essentially need it (mostly all SVR4-derivates) it can be also enabled
9029 manually via the Rule SHARED_CORE. This can be interesting in the future
9030 where we perhaps exploit this libhttpd.so mechanism for providing nifty
9031 features like graceful upgrades, or whatever.
9032 [Ralf S. Engelschall, Martin Kraemer]
9034 *) Build the libraries before building the rest of the tools. [Ben Hyde]
9036 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
9037 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
9038 conventions while "clean" removes only stuff created by "all" targets,
9039 "distclean" additionally removes the stuff from the configuration
9040 process. This way "make distclean" (hence the name) provides a fresh
9041 source tree as it was for distribution.
9042 [Ralf S. Engelschall]
9044 *) Allow top-level (APACI) Makefile to break on build errors
9045 the same way the src/ subtree Makefiles breaks on them by replacing the
9046 initial APACI sed-subdir-display-kludge with a more clean
9047 variable-passing-solution: variable SDP can optionally hold the subdir
9048 prefix which is consistently used for displaying the subdir movement.
9049 This way even the top-level Makefile can stop correctly on errors as the
9050 user expects. [Ralf S. Engelschall]
9052 *) Fixed ordering of argument checks for RewriteBase directive.
9053 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
9055 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
9056 indicating that a module is being compiled for dynamic loading. Also
9057 remove #define IS_MODULE from modules and add SHARED_MODULE define
9058 to the mak/dsp files. [Alexei Kosut]
9060 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
9061 since we are now logging APLOG_WARNING by default. [Roy Fielding]
9063 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
9065 *) Add documentation file and src/Configuration.tmpl entry for the
9066 experimental mod_mmap_static module. Because although it is and marked as
9067 an experimental one it is distributed and thus should be documented and
9068 prepared for configuration the same way as all others modules.
9069 [Ralf S. Engelschall]
9071 *) Add query (-q) option to apxs support tool to be able to manually query
9072 specific settings from apxs. This is needed for instance when you
9073 manually want to access Apache's header files and you need to assemble
9074 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
9075 [Ralf S. Engelschall]
9077 *) Now src/Configure uses a fallback strategy for the shared object support
9078 on platforms where no explicit information is available: If a Perl
9079 installation exists we ask it about its shared object support and if it's
9080 the dlopen-style one we shamelessly guess the compiler and linker flags
9081 for creating shared objects from Perls knowledge. Of course, the user is
9082 warning about what we are doing and informed that he should send us
9083 the guessed flags when they work. [Ralf S. Engelschall]
9085 *) Provide APACI --without-support option to be able to disable the build
9086 and installation of the support tools from the src/support/ area.
9087 Although its useful to have these installed per default we should provide
9088 a way to compile and install without them for backward-compatibility.
9089 [Ralf S. Engelschall]
9091 *) Add of the new APache eXtenSion (apxs) support tool for building and
9092 installing modules into an _already installed_ Apache package through the
9093 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
9094 this approach actually doesn't need the Apache source tree. The
9095 (APACI-installed) server package is enough, because this now includes the
9096 Apache C header files (PREFIX/include) and the new APXS tool
9097 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
9098 module authors to build their Apache modules _OUTSIDE_ the Apache source
9099 tree while avoiding them to fiddle around with the totally platform
9100 dependend way of compiling DSO files. The tool supports all ranges of
9101 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
9102 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
9103 on-the-fly generate a minimalistic Makefile and sample module for the
9104 first step to provide both a quick success event and to demonstrate the
9105 APXS mechanism to module authors. [Ralf S. Engelschall]
9107 *) Fix core dumps in use of CONNECT in proxy.
9108 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
9110 *) Modify the log directives in httpd.conf-dist files to use CustomLog
9111 so that users have examples of how CustomLog can be used.
9114 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
9115 the Apache distribution tree. Until Apache 1.3 there was no real
9116 out-of-the-box batch-capable build and installation procedure for the
9117 complete Apache package. This is now provided by a top-level "configure"
9118 script and a corresponding top-level "Makefile.tmpl" file. The goal is
9119 to provide a GNU Autoconf-style frontend which is capable to both drive
9120 the old src/Configure stuff in batch and additionally installs the
9121 package with a GNU-conforming directory layout. Any options from the old
9122 configuration scheme are available plus a lot of new options for flexibly
9123 customizing Apache. [Ralf S. Engelschall]
9125 *) The floating point ap_snprintf code wasn't threadsafe.

9135 Configure knows which CC we are using. [Jim Jagielski]
9137 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
9138 was defined in a parent directory. [Lars Eilebrecht]
9140 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
9141 a generic printf-style routine that can call arbitrary output
9142 routines. Use this to replace http_bprintf.c. Add new routines
9143 psprintf(), pvsprintf() which allocate the exact amount of memory
9144 required for a string from a pool. Use psprintf() to clean up
9145 various bits of code which used ap_snprintf()/pstrdup().
9148 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
9149 ap_snprintf() has different semantics and formatting codes than
9150 snprintf(). [Dean Gaudet]
9152 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
9153 is necessary on at least Solaris where the /etc/rc?.d scripts
9154 are run with these signals ignored, and "SIG_IGN" settings are
9155 maintained across exec().

9183 *) Allow %2F in two situations: 1) it is in the query part of the URI,
9184 therefore not exposed to %2F -> '/' translations and 2) the request
9185 is a proxy request, so we're not dealing with a local resource anyway.
9186 Without this, the proxy would fail to work for any URL's with
9187 %2f in them (occurs quite often in

9208 the mod_proxy.html and corrected the hyperlink to it in the
9209 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
9211 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
9212 faster [Martin Kraemer]
9214 *) Make Configure die when you give it an unknown command switch.
9217 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
9218 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
9219 and per default compiled support programs have manual pages - just to
9220 document our stuff a little bit more and to be able to do really
9221 Unix-like installations ;-) [Ralf S. Engelschall]
9223 *) Major cleanups to the Configure script to make it and its generated
9224 Makefiles again readable and maintainable: add SRCDIR option, removed
9225 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
9226 generated sections, consequently added Makefile headers with inheritance
9227 information, added subdir movement messages for easier following where
9228 the build process currently stays (more verbose then standard Make, less
9229 verbose than GNU make), same style to comments in the Configure script,
9230 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
9232 *) Add the new ApacheBench program "ab" to src/support/: This is derived
9233 from the ZeusBench benchmarking program and can be used to determine the
9234 response performance of an Apache installation. This version is
9235 officially licensed with Zeus Technology, Ltd. See the license agreement
9236 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
9237 [Ralf S. Engelschall]
9239 *) API: Various core functions that are definately not part of the API
9240 have been made static, and a few have been marked API_EXPORT. Still
9241 more have been marked CORE_EXPORT and are not intended for general
9242 use by modules. [Doug MacEachern, Dean Gaudet]
9244 *) mod_proxy was not clearing the Proxy-Connection header from
9245 requests; now it does. This did not violate any spec, however
9246 causes poor interactions when you are talking to remote proxies.
9247 [Marc Slemko] PR#1741
9249 *) Various cleanups to the command line interface and manual pages.
9250 [Ralf S. Engelschall]
9252 *) cfg_getline() was not properly handling lines that did not end
9253 with a line termination character. [Marc Slemko] PR#1869, 1909
9255 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
9257 *) Clean up some undocumented behavior of mod_setenvif related to
9258 "merging" two SetEnvIf directives when they match the same header
9259 and regex. Document that mod_setenvif will perform comparisons in
9260 the order they appear in the config file. Optimize mod_setenvif by
9261 doing more work at config time rather than at runtime.
9264 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
9265 to allow for modules to overrule them and to reduce redefinition
9266 warnings [Jim Jagielski]
9268 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
9271 *) Making the hard-coded cross-module function call mime_find_ct() (from
9272 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
9273 checking is really called even for proxy requests except for URLs with
9274 HTTP schemes (because there we can optimize by not running the type
9275 checking hooks due to the fact that the proxy gets the MIME Content-type
9276 from the remote host later). This change cleans up mod_mime by removing
9277 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
9278 especially unbundles mod_proxy and mod_mime. This way they both now can
9279 be compiled as shared objects and are no longer tied together.
9280 [Ralf S. Engelschall]
9282 *) util.c cleanup and speedup. [Dean Gaudet]
9284 *) API: Clarification, pstrndup() will always copy n bytes of the source
9285 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
9287 *) Mark module command_rec and handler_rec structures const so that they
9288 end up in the read-only data section (and are friendlier to systems
9289 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
9291 *) Add check to the "Port" directive to make sure the specified
9292 port is in the appropriate range. [Ben Hyde]
9294 *) Performance improvements to invoke_handler().
9295 [Dmitry Khrustalev <dima@bog.msu.su>]
9297 *) Added support for building shared objects even for library-style modules
9298 (which are built from more than one object file). This now provides the
9299 ability to build mod_proxy as a shared object module. Additionally
9300 modules like mod_example are now also supported for shared object
9301 building because the generated Makefiles now no longer assume there is at
9302 least one statically linked module. [Ralf S. Engelschall]
9304 *) API: Clarify usage of content_type, handler, content_encoding,
9305 content_language and content_languages fields in request_rec. They
9306 must always be lowercased; and the strings pointed to shouldn't
9307 be modified (you must copy them to modify them). Fix a few bugs
9308 related to this. [Dean Gaudet]
9310 *) API: Clarification: except for RAW_ARGS, all command handlers can
9311 treat the char * parameters as permanent, and modifiable. There
9312 is no need to pstrdup() them. Clean up some needless pstrdup().
9315 *) Now mod_so keeps track of which module shared objects with which names
9316 are loaded and thus avoids multiple loading and unloading and irritating
9317 error_log messages. [Ralf S. Engelschall]
9319 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
9320 environment variable in the apache core. But that tweaking interferes
9321 with mod_setenv. So don't tweak if the user has specified an explicit
9322 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
9324 *) rputs() did not calculate r->sent_bodyct properly.
9325 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
9327 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
9328 name, or left unset if this value is unavailable. Apache was setting
9329 it to the IP address when unavailable.
9330 [Tony Finch <fanf@demon.net>] PR#1925
9332 *) Various improvements to the configuration and build support for compiling
9333 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
9334 OSF1 support with GCC and vendor compilers was added. This way shared
9335 object support is now provided out-of-the-box for FreeBSD, Linux,
9336 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
9337 [Ralf S. Engelschall]
9339 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
9340 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
9341 and USE_OS2_SCOREBOARD. [Dean Gaudet]
9343 *) Fix one more special locking problem for RewriteMap programs in
9344 mod_rewrite: According to the documentation of flock(), "Locks are on
9345 files, not file descriptors. That is, file descriptors duplicated
9346 through dup(2) or fork(2) do not result in multiple instances of a lock,
9347 but rather multiple references to a single lock. If a process holding a
9348 lock on a file forks and the child explicitly unlocks the file, the
9349 parent will lose its lock.". To overcome this we have to make sure the
9350 RewriteLock file is opened _AFTER_ the childs were spawned which is now
9351 the case by opening it in the child_init instead of the module_init API
9352 hook. [Ralf S. Engelschall] PR#1029
9354 *) Change to Location and LocationMatch semantics. LocationMatch no
9355 longer lets a single slash match multiple adjacent slashes in the
9356 URL. This change is for consistency with RewriteRule and
9357 AliasMatch. Multiple slashes have meaning in URLs that they do
9358 not have in (some) filesystems. Location on the other hand can
9359 be considered a shorthand for a more complicated regex, and it
9360 does match multiple slashes with a single slash -- which is
9361 also consistent with the Alias directive.
9362 [Dean Gaudet] related PR#1440
9364 *) Fix bug with mod_mime_magic causing certain files, including files
9365 of length 0, to result in no response from the server.
9368 *) The Configure script now generates src/include/ap_config.h which
9369 contains the set of defines used when Apache is compiled on a platform.
9370 This file can then be included by external modules before including
9371 any Apache header files in case they are being built separately from
9372 Apache. Along with this change, a couple of minor changes were
9373 made to make Apache's #defines coexist peacefully with any autoconf
9374 defines an external module might have. [Rasmus Lerdorf]
9376 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9377 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9378 chance by the API to initialize its per-server configuration and thus
9379 receives the wrong one from the main server. This is now avoided by
9380 remembering the server together with the config structure while
9381 configuring and later assuming there is no config when we see a
9382 difference between the remembered server and the one calling us.
9383 [Ralf S. Engelschall] PR#1790
9385 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9386 is automatically disabled under configure time when the dbm_xxx functions
9387 are not available. Second, two heavy source code errors in the DBM
9388 support code were fixed. This makes DBM RewriteMap's usable again after
9389 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9391 *) Now all configuration files support Unix-style line-continuation via
9392 the trailing backslash ("\") character. This enables us to write down
9393 complex or just very long directives in a more readable way. The
9394 backslash character has to be really the last character before the
9395 newline and it has not been prefixed by another (escaping) backslash.
9396 [Ralf S. Engelschall]
9398 *) When using ProxyPass the ?querystring was not passed correctly.
9399 [Joel Truher <truher@wired.com>]
9401 *) To deal with modules being compiled and [dynamically] linked
9402 at a different time from the core, the SERVER_VERSION and
9403 SERVER_BUILT symbols have been abstracted through the new
9404 API routines apapi_get_server_version() and apapi_get_server_built().
9407 *) WIN32: Preserve trailing slash in canonical path (and hence
9408 in PATH_INFO). [Paul Sutton, Ben Laurie]
9410 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
9411 depending on the rev of Solaris and what mixture of modules
9412 are in use. So it has been disabled, and Solaris is back to
9413 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9414 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9415 up static content only servers. Or it may fail unpredictably.
9416 [Dean Gaudet] PR#1779, 1854, 1904
9418 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9421 *) API: Rewrite of absoluteURI handling, and in particular how
9422 absoluteURIs match vhosts. Unless a request is a proxy request, a
9423 "http://host" url is treated as if a similar "Host:" header had been
9424 supplied. This change was made to support future HTTP/1.x protocols
9425 which may require clients to send absoluteURIs for all requests.
9427 In order to achieve this change subtle changes were made to the API. In a
9428 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9429 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9430 by the core, modules must set it during the post_read_request or
9431 translate_names phase.
9433 Plus changes to the virtualhost test suite for absoluteURI testing.
9435 This fixes several bugs with the proxy proxying requests to vhosts
9436 managed by the same httpd.
9439 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
9440 code from mod_rewrite. The vhost matching is now performed by a
9441 globally available function matches_request_vhost(). [Dean Gaudet]
9443 *) Reduce memory usage, and speed up ServerAlias support. As a
9444 side-effect users can list multiple ServerAlias directives
9445 and they're all considered.

9452 *) Make \\ behave as expected. [Ronald.Tschalaer@psi.ch]
9454 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
9455 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
9457 *) API: A new source module main/util_uri.c; It contains a routine
9458 parse_uri_components() and friends which breaks a URI into its component
9459 parts. These parts are stored in a uri_components structure called
9460 parsed_uri within each request_rec, and are available to all modules.
9461 Additionally, an unparse routine is supplied which re-assembles the URI
9462 components back to an URI, optionally hiding the username:password@ part
9463 from ftp proxy requests, and other useful routines. Within the structure,
9464 you find on a ready-for-use basis:
9465 scheme; /* scheme ("http"/"ftp"/...) */
9466 hostinfo; /* combined [user[:password]@]host[:port] */
9467 user; /* user name, as in http://user:passwd@host:port/ */
9468 password; /* password, as in http://user:passwd@host:port/ */
9469 hostname; /* hostname from URI (or from Host: header) */
9470 port_str; /* port string (integer representation is in "port") */
9471 path; /* the request path (or "/" if only scheme://host was given) */
9472 query; /* Everything after a '?' in the path, if present */
9473 fragment; /* Trailing "#fragment" string, if present */
9474 This is meant to serve as the platform for *BIG* savings in
9475 code complexity for the proxy module (and maybe the vhost logic).
9478 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
9479 ${map:key}) available for all location where a string is created in
9480 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
9481 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
9482 possible expansions are consequently usable at all string creation
9483 locations. [Ralf S. Engelschall]
9485 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
9486 and not 1) and the per-virtual-server merging of directives. Now all
9487 directives except `RewriteEngine' and `RewriteOption' are either
9488 completely overridden (default) or completely inherited (when
9489 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
9491 *) Fix `RewriteMap' program lookup in situations where such maps are
9492 defined but disabled (`RewriteEngine off') in per-server context.
9493 [Ralf S. Engelschall] PR#1431
9495 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
9496 server to bind to port 0 rather than 80. [Dean Gaudet]
9498 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
9499 (like SunOS and FreeBSD) which don't accept the locking of pipes
9500 directly. A new directive RewriteLock is introduced which can be used to
9501 setup a separate locking file which then is used for synchronization.

9505 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently

9507 value is stored by running "apache -i -d serverroot". [Paul Sutton]

9516 *) The mod_setenvif BrowserMatch backwards compatibility command did not
9517 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
9519 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
9520 type but with a special post-processing for the looked-up value: It
9521 parses it into alternatives according to `|' chars and then only one
9522 particular alternative is chosen randomly (this is an essential
9523 functionality needed for balancing between backend-servers when using
9524 Apache as a Reverse Proxy. The looked up value here is a list of
9525 servers). Second, `int' with the built-in maps named `tolower' and
9526 `toupper' which can be used to map URL parts to a fixed case (this is an
9527 essential feature to fix the case of server names when doing mass
9528 virtual-hosting with the help of mod_rewrite instead of using
9529 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
9530 Jay Soffian <jay@cimedia.com>] PR#1631
9532 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
9533 This directive lets Apache adjust the URL in Location-headers on HTTP
9534 redirect responses sent by the remote server. This way the virtually
9535 mapped area is no longer left on redirects and thus by-passed which is
9536 especially essential when running Apache as a reverse proxy.

9652 preserves the encoding the client requests (for example if
9653 it requests x-gzip, then Apache will respond with x-gzip
9654 in the Content-Encoding header).

9704 server setting inside vhosts (only an issue when you have no
9705 <Directory> or other section containing an Options that affects
9706 a request). Options +foo or -foo in the main_server wouldn't
9707 affect the main_server's lookup defaults. [Dean Gaudet]
9709 *) Variable 'cwd' was being used pointlessly before being set.
9712 *) r->allowed handling cleaned up in the standard modules.
9715 *) Some case-sensitivity issues cleaned up to be consistent with
9716 RFC2068. [Dean Gaudet]
9718 *) SIGURG doesn't exist everywhere.
9719 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
9721 *) mod_unique_id was erroneously generating a second unique id when
9722 an internal redirect occured. Such redirects occur, for example,
9723 when processing a DirectoryIndex match. [Dean Gaudet]
9725 *) API: table_add, table_merge, and table_set include implicit pstrdup()
9726 of the key and value. But in many cases this is not required
9727 because the key/value is a constant, or the value has been built
9728 by pstrcat() or other similar means. New routines table_addn,
9729 table_mergen, and table_setn have been added to the API, these
9730 routines do not pstrdup() their arguments. The core code and
9731 standard modules were changed to take advantage of these routines.
9732 The resulting server is up to 20% faster in some situations.
9734 Note that it is easy to get code subtly wrong if you pass a key/value
9735 which is in a pool other than the pool of the table. The only
9736 safe thing to do is to pass key/values which are in the pool of
9737 the table, or in one of the ancestors of the pool of the table.
9738 i.e. if the table is part of a subrequest, a value from the main
9739 request's pool is OK since the subrequest pool is a sub_pool of the
9740 main request's pool (and therefore has a lifespan at most as long as
9741 the main pool). There is debugging code which can detect improper
9742 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
9743 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
9745 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
9746 which don't exist on disk more gracefully; handles vhosts properly.
9747 Update documentation to reflect the code -- if there's no
9748 MimeMagicFile directive then the module is not enabled.
9751 *) PORT: Some older *nix dialects cannot automatically start scripts
9752 which begin with a #! interpreter line (the shell starts the scripts
9753 appropriately on these platforms). Apache now supports starting of
9754 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
9755 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
9758 *) API: "typedef array_header table" removed from alloc.h, folks should
9759 have been writing to use table as if it were an opaque type, but even
9760 some standard modules got this wrong. By changing the definition
9761 to "typedef struct table table" module authors will receive compile
9762 time warnings that they're doing the wrong thing. This change
9763 facilitates future changes with more sophisticated table
9764 structures. Specifically, module authors should be using table_elts()
9765 to get access to an array_header * for the table. [Dean Gaudet]
9767 *) API: Renamed new_connection() to avoid namespace collision with LDAP
9768 library routines. [Ken Coar, Rasmus Lerdorf]
9770 *) WIN32: mod_speling is now available on the Win32 platform.
9773 *) For clarity the following compile time definition was changed:
9775 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
9777 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
9778 and not be a general notice that the OS has mmap(). Now the
9779 HAVE_MMAP/SHMGET #defines strictly are informational that the
9780 OS has that method of shared memory; the type to use for
9781 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
9782 and USE_SHMGET_SCOREBOARD). This allows outside modules to
9783 determine if shared memory is available and allows Apache
9784 to determine the best method to use for the scoreboard.
9787 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
9788 as do various earlier versions. It should be safe on all versions.
9789 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
9790 the slack code. A few other cleanups for Unixware.

9813 The choice of flock vs. fcntl was made based on timings which showed that
9814 even on non-NFS, non-exported filesystems fcntl() was an order of

9879 underscores over any character outside the regex. This

10222 Document this a bit more in src/PORTING. [Dean Gaudet] PR#467
10224 *) Ensure that one copy of config warnings makes it to the
10225 error_log. [Dean Gaudet]
10227 *) Invent new structure and associated methods to handle config file
10228 reading. Add "custom" hook to use config file cfg_getline() on
10229 something which is not a FILE* [Martin Kraemer]
10231 *) Make single-exe Windows install. [Ben Laurie and Eric Esselink]
10233 *) WIN32: Make CGI work under Win95. [Ben Laurie and Paul Sutton]
10235 *) WIN32: Make index.html and friends work under Win95. [Ben Laurie]
10237 *) PORT: Solaris 2.4 needs Spencer regex, the system regex is broken.

10254 __NetBSD__. Workaround by defining NETBSD.
10255 [Chris Craft <ccraft@cncc.cc.co.us>] PR#977
10257 *) PORT: UnixWare 2.x requires -lgen for syslog.
10258 [Hans Snijder <hs@meganet.nl>] PR#1249
10260 *) PORT: ULTRIX appears to not have syslog.
10261 [Lars Eilebrecht <Lars.Eilebrecht@unix-ag.org>]
10263 *) PORT: Basic Gemini port (treat it like unixware212).
10264 ["Pavel Yakovlev (Paul McHacker)" <hac@tomcat.olly.ru>]
10266 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
10267 use USE_SHMGET_SCOREBOARD.
10270 *) Various improvements in detecting config file errors (missing closing
10271 directives for <Directory>, <Files> etc. blocks, prohibiting global
10272 server settings in <VirtualHost> blocks, flagging unhandled multiple
10273 arguments to <Directory>, <Files> etc.)
10276 *) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
10277 variable to provide this one to suexec'd CGIs, too.
10278 [M.D.Parker <mdpc@netcom.com>] PR#1284
10280 *) New support tool: src/support/split-logfile, a sample Perl script which
10281 splits up a combined access log into separate files based on the
10282 name of the virtual host (listed first in the log records by "%v").
10285 Changes with Apache 1.3b2 (there is no 1.3b1)
10287 *) TestCompile was not passing $LIBS [Dean Gaudet]
10289 *) Makefile.tmpl was not using $CFLAGS in the link phase.
10292 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
10293 rudimentary memory debugger which can be used on live servers with
10294 low impact -- it sets all allocated and freed memory bytes to 0xa5.
10295 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
10296 and free() for each object. This is far more expensive and should
10297 only be used for testing with tools such as Electric Fence and
10298 Purify. See main/alloc.c for more details. [Dean Gaudet]
10300 *) Configure uses a sh trap and didn't set its exitcode properly.
10301 [Dean Gaudet] PR#1159
10303 *) Yet another vhost revamp. Add the NameVirtualHost directive which
10304 explicitly lists the ip:port pairs that are to be used for name-vhosts.
10305 From a given ip:port, regardless what the Host: header is, you can
10306 only reach the vhosts defined on that ip:port. The precedence of
10307 vhosts was reversed to match other precedences in the config --
10308 the earlier vhosts override the later vhosts. All vhost matching was
10309 moved into http_vhost.[ch]. [Dean Gaudet]
10311 *) ap_inline can be used to force inlining. GNUC __attribute__() can
10312 be used for whatever reason is appropriate (i.e. format() warnings
10313 for printf style functions). Both are enabled only with
10314 gcc >= 2.7.x (so that we have fewer support issues with older
10315 versions). [Dean Gaudet]
10317 *) Fix support for Proxy Authentication (we were testing the response
10318 status too early). [Marc Slemko]
10320 *) CoreDumpDirectory directive directs where the core file is
10321 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
10322 received. [Marc Slemko, Dean Gaudet]
10324 *) PORT: Support for Atari MINT.
10325 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
10327 *) When booting, apache will now detach itself from stdin, stdout,
10328 and stderr. stderr will not be detached until after the config
10329 files have been read so you will be able to see initial error
10330 messages. After that all errors are logged in the error_log.
10331 This makes it more convenient to start apache via rsh, ssh,
10332 or crontabs. [Dean Gaudet] PR#523
10334 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10335 Also removed the auto-generated link to www.apache.org that was the
10336 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10338 *) send_fb would not detect aborted connections in some situations.
10341 *) mod_include would use uninitialized data when parsing certain
10342 expressions involving && and ||. [Brian Slesinsky] PR#1139
10344 *) mod_imap should only handle GET methods. [Jay Bloodworth]
10346 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10348 *) mod_autoindex improperly counted &escapes; as more than one
10349 character in the description. It also improperly truncated
10350 descriptions that were exactly the maximum length.
10353 *) RedirectMatch was not properly escaping the result (PR#1155). Also
10354 "RedirectMatch /advertiser/(.*) $1" is now permitted.
10357 *) mod_include now uses symbolic names to check for request success
10358 and return HTTP errors, and correctly handles all types of
10359 redirections (previously it only did temporary redirect correctly).
10360 [Ken Coar, Roy Fielding]
10362 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10363 r->filename. Since those two are meant to be in sync with each other
10364 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
10366 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
10367 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
10369 *) Inetd mode (which is buggy) uses timeouts without having setup the
10370 jmpbuffer. [Dean Gaudet] PR#1064
10372 *) Work around problem under Linux where a child will start looping
10373 reporting a select error over and over.
10374 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
10376 *) Fixed error in proxy_util.c when looping through multiple host IP
10377 addresses. [Lars Eilebrecht] PR#974
10379 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10380 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10381 bytes before writing, but it will never split a log entry across a
10382 buffer boundary. [Dean Gaudet]
10384 *) API: the short_score record has been split into two pieces, one which
10385 the parent writes on, and one which the child writes on. As part of
10386 this change the get_scoreboard_info() function was removed, and
10387 scoreboard_image was exported. This change fixes a race condition
10388 in file based scoreboard systems, and speeds up changes involving the
10389 scoreboard in earlier 1.3 development. [Dean Gaudet]
10391 *) API: New register_other_child() API (see http_main.h) which allows
10392 modules to register children with the parent for maintenance. It
10393 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10395 *) API: New piped_log API (see http_log.h) which implements piped logs,
10396 and will use register_other_child to implement reliable piped logs
10397 when it is available. The reliable piped logs part can be disabled
10398 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10399 logs is only available on Unix. [Dean Gaudet]
10401 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10402 meets_conditions(). This allows conditional HTTP selection to be
10403 handled separately from the storing of the header fields, and provides
10404 the ability for CGIs to set their own ETags for conditional checking.
10405 [Ken Coar, Roy Fielding] PR#895
10407 *) Changes to mod_log_config to allow naming of format strings.
10408 Format nicknames are defined with "LogFormat fmt nickname", and can
10409 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
10412 *) New module, "mod_speling", which can help find files even when
10413 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
10415 *) API: New function child_terminate() triggers the child process to
10416 exit, while allowing the child finish what it needs to for the
10417 current request first.
10418 [Doug MacEachern, Alexei Kosut]
10420 *) Windows now defaults to using full status reports with mod_status.
10421 [Alexei Kosut] PR #1094
10423 *) *Really* disable all mod_rewrite operations if the engine is off.
10424 Some things (like RewriteMaps) were checked/performed even if they
10425 weren't supposed to be. [Ken Coar] PR #991
10427 *) Implement a new timer scheme which eliminates the need to call alarm() all
10428 the time. Instead a counter in the scoreboard for each child is used to
10429 show when the child has made forward progress. The parent samples this
10430 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10431 progress has been made in the timeout period. This reduces the static
10432 request best-case syscall count to 22 from 29. This scheme is only
10433 used by systems with memory-based scoreboards. [Dean Gaudet]
10435 *) The proxy now properly handles CONNECT requests which are sent
10436 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10438 *) A script called apachectl has been added to the support
10439 directory. This script allows you to do things such as
10440 "apachectl start" and "apachectl restart" from the command
10441 line. [Marc Slemko]
10443 *) Modules and core routines are now put into libraries, which
10444 simplifies the link line tremendously (among other advantages).
10447 *) Some of the MD5 names defined in Apache have been renamed to have
10448 an `ap_' prefix to avoid conflicts with routines supplied by
10449 external libraries. [Ken Coar]
10451 *) Removal of mod_auth_msql.c from the distribution. There are many
10452 other options for databases today. Rather than offer one option,
10453 offer none at this time. mod_auth_msql and other SQL database
10454 authentication modules can be found at the Apache Module Registry.
10455 http://modules.apache.org/ It would be nice to offer a generic
10456 mod_auth_sql option in the near future.
10458 *) PORT: BeOS support added [Alexei Kosut]
10460 *) Configure no longer accepts the -make option, since it creates
10461 Makefile on the fly based on Makefile.tmpl and Configuration.
10463 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
10464 of forcibly killing off all its processes and exiting without
10465 cleaning up. [Alexei Kosut]
10467 *) API: A new field in the request_rec, r->mtime, has been added to
10468 avoid gratuitous parsing of date strings. It is intended to hold
10469 the last-modified date of the resource (if applicable). An
10470 update_mtime() routine has also been added to advance it if
10471 appropriate. [Roy Fielding, Ken Coar]
10473 *) SECURITY: If a htaccess file can not be read due to bad permissions,
10474 deny access to the directory with a HTTP_FORBIDDEN. The previous
10475 behavior was to ignore the htaccess file if it could not be read.
10476 This change may make some setups with unreadable htaccess files
10477 stop working. [Marc Slemko] PR#817
10479 *) Add aplog_error() providing a mechanism to define levels of
10480 verbosity to the server error logging. This addition also provides
10481 the ability to log errors using syslogd. Error logging is configurable
10482 on a per-server basis using the LogLevel directive. Conversion
10483 of log_*() in progress. [Randy Terbush]
10485 *) Further enhance aplog_error() to not log filename, line number, and
10486 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
10488 *) WIN32: Canonicalise filenames under Win32. Short filenames are
10489 converted to long ones. Backslashes are converted to forward
10490 slashes. Case is converted to lower. Parts of URLs that do not
10491 correspond to files are left completely alone. [Ben Laurie]
10493 *) PORT: 2 new OSs added to the list of ports:
10494 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
10495 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
10497 *) Add the server version (SERVER_VERSION macro) to the "server
10498 configured and running" entry in the error_log. Also build an
10499 object file at link-time that contains the current time
10500 (SERVER_BUILT global const char[]), and include that in the
10501 message. [Ken Coar]
10503 *) Set r->headers_out when sending responses from the proxy.
10504 This fixes things such as the logging of headers sent from
10505 the proxy. [Marc Slemko] PR#659
10507 *) support/httpd_monitor is no longer distributed because the
10508 scoreboard should not be file based if at all possible. Use
10509 mod_status to see current server snapshot.
10511 *) (set_file_slot): New function, allowing auth directives to be
10512 independent of the server root, so the server documents can be
10513 moved to a different directory or machine more easily.
10514 [David J. MacKenzie]
10516 *) If no TransferLog is given explicitly, decline
10517 to log. This supports coexistence with other logging modules,
10518 such as the custom one that UUNET uses. [David J. MacKenzie]
10520 *) Check for titles in server-parsed HTML files.
10521 Ignore leading newlines and returns in titles. The old behavior
10522 of replacing a newline after <title> with a space causes the
10523 title to be misaligned in the listing. [David J. MacKenzie]
10525 *) Change mod_cern_meta to be configurable on a per-directory basis.
10526 [David J. MacKenzie]
10528 *) Add 'Include' directive to allow inclusion of configuration
10529 files within configuration files. [Randy Terbush]
10531 *) Proxy errors on connect() are logged to the error_log (nothing
10532 new); now they include the IP address and port that failed
10533 (*that's* new). [Ken Coar, Marc Slemko] PR#352
10535 *) Various architectures now define USE_MMAP_FILES which causes
10536 the server to use mmap() for static files. There are two
10537 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
10538 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
10539 number of bytes written in one cycle from a single mmap()d object,
10540 default 32768). [Dean Gaudet]
10542 *) API: Added post_read_request API phase which is run right after reading
10543 the request from a client, or right after an internal redirect. It is
10544 useful for modules setting environment variables that depend only on
10545 the headers/contents of the request. It does not run during subrequests
10546 because subrequests inherit pretty much everything from the main
10547 request. [Dean Gaudet]
10549 *) Added mod_unique_id which is used to generate a unique identifier for
10550 each hit, available in the environment variable UNIQUE_ID.
10553 *) init_modules is now called after the error logs have been opened. This
10554 allows modules to emit information messages into the error logs.
10557 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10558 information for case where proxy module is not available. [Marc Slemko]
10560 *) PORT: Apache has need for mutexes to serialize its children around
10561 accept. In prior versions either fcntl file locking or flock file
10562 locking were used. The method is chosen by the definition of
10563 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
10564 and FLOCK for flock(). New options have been added:
10565 - SYSVSEM to use System V style semaphores
10566 - PTHREAD to use POSIX threads (appears to work on Solaris only)
10567 - USLOCK to use IRIX uslock
10568 Based on timing various techniques, the following changes were made
10570 - Linux 2.x uses flock instead of fcntl
10571 - Solaris 2.x uses pthreads
10572 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
10573 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
10574 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
10575 Martijn Koster <m.koster@pobox.com>]
10577 *) PORT: The semantics of accept/select make it very desirable to use
10578 mutexes to serialize accept when multiple Listens are in use. But
10579 in the case where only a single socket is open it is sometimes
10580 redundant to serialize accept(). Not all unixes do a good job with
10581 potentially dozens of children blocked on accept() on the same
10582 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
10583 the server will avoid serialization when listening on only one socket,
10584 and use serialization when listening on multiple sockets.
10585 [Dean Gaudet] PR#467
10587 *) Configure changes: TestLib replaced by TestCompile, which has
10588 some additional capability (such as doing a sanity check of
10589 the compiler and flags selected); the version of Solaris is now
10590 available via the #define value of SOLARIS2; IRIX n32bit libs
10591 now supported and selectable by new Configuration Rule: IRIXN32;
10592 We no longer default to -O2 optimization. [Jim Jagielski]
10594 *) Updated Configure: Configuration now uses AddModule to specify
10595 module source or binary file location, relative to src directory.
10596 Modules can be dropped into modules/extra, or in their own
10597 directory, and modules can come with a Makefile or Configure can
10598 create one. Modules can add compiler or library information to
10599 generated Makefiles. [Paul Sutton]
10601 *) Source core re-organisation: distributed modules are now in
10602 modules/standard. All other source code is in main. OS-specific
10603 code is in os/{unix,emx,win32} directories. [Paul Sutton]
10605 *) mod_browser has been removed, since it's replaced by mod_setenvif.
10608 *) Fix another long-standing bug in sub_req_lookup_file where it would
10609 happily skip past access checks on subdirectories looked up with
10610 relative paths. (It's used by mod_dir, mod_negotiation,
10611 and mod_include.) [Dean Gaudet]
10613 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
10614 N is the number of <Directory> sections, and M is the number of
10615 components in the filename of an object.
10617 To achieve this optimization the following config changes were made:
10618 - Wildcards (* and ?, not the regex forms) in <Directory>s,
10619 <Files>s, and <Location>s now treat a slash as a special
10620 character. For example "/home/*/public_html" previously would
10621 match "/home/a/andrew/public_html", now it only matches things
10622 like "/home/bob/public_html". This mimics /bin/sh behaviour.
10623 - It's possible now to use [] wildcarding in <Directory>, <Files>
10625 - Regex <Directory>s are applied after all non-regex <Directory>s.
10629 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
10630 and corrupted paths. [Dean Gaudet]
10632 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
10633 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
10634 be accessed now via backreferences $1..$9 in RewriteConds test-against
10635 strings in addition to RewriteRules subst string. Second the grouped
10636 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
10637 via backreferences %1..%9 both in following RewriteCond test-against
10638 strings and RewriteRules subst string. This provides maximum flexibility
10639 through the use of backreferences.
10640 Additionally the rewriting engine was cleaned up by putting common
10641 code to the new expand_backrefs_inbuffer() function.
10642 [Ralf S. Engelschall]
10644 *) When merging the main server's <Directory> and <Location> sections into
10645 a vhost, put the main server's first and the vhost's second. Otherwise
10646 the vhost can't override the main server. [Dean Gaudet] PR#717
10648 *) The <Directory> code would merge and re-merge the same section after
10649 a match was found, possibly causing problems with some modules.
10652 *) ip-based vhosts are stored and queried using a hashing function, which
10653 has been shown to improve performance on servers with many ip-vhosts.
10654 Some other changes had to be made to accommodate this:
10655 - the * address for vhosts now behaves like _default_
10656 - the matching process now is:
10657 - match an ip-vhost directly via hash (possibly matches main
10659 - if that fails, just pretend it matched the main server
10660 - if so far only the main server has been matched, perform
10661 name-based lookups (ServerName, ServerAlias, ServerPath)
10662 *only on name-based vhosts*
10663 - if they fail, look for _default_ vhosts
10664 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
10666 *) dbmmanage overhaul:
10667 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
10668 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
10669 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
10670 - provide better seed for rand
10671 - prompt for password as per getpass(3) (turn off echo, read from
10673 - use "newstyle" crypt based on $Config{osname} ($^O)
10674 - will not add a user if already in database, use new `update' command
10676 - added `check' command to check a users' password
10677 - added `import' command to convert existing password text-files or
10678 dbm files exported with `view'
10679 - more descriptive usage, general cleanup, 'use strict' clean, etc.
10682 *) Added psocket() which is a pool form of socket(), various places within
10683 the proxy weren't properly blocking alarms while registering the cleanup
10684 for its sockets. bclose() now uses pclose() and pclosesocket(). There
10685 was a bug where the client socket was being close()d twice due a still
10686 registered cleanup. [Dean Gaudet]
10688 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
10691 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
10692 [Jason Venner <jason@idiom.com>] PR#667
10694 *) Enable ``=""'' for RewriteCond directives to match against
10695 the empty string. This is the preferred way instead of ``^$''.
10696 [Ralf S. Engelschall]
10698 *) Fixed an infinite loop in mod_imap for references above the server root
10699 [Dean Gaudet] PR#748
10701 *) mod_proxy now has a ReceiveBufferSize directive, similar to
10702 SendBufferSize, so that the TCP window can be set appropriately
10703 for LFNs. [Phillip A. Prindeville]
10705 *) mod_browser has been replaced by the more general mod_setenvif
10706 (courtesy of Paul Sutton). BrowserMatch* directives are still
10707 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
10708 UnSetEnvIfZero directives. [Ken Coar]
10710 *) "HostnameLookups double" forces double-reverse DNS to succeed in
10711 order for remote_host to be set (for logging, or for the env var
10712 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
10715 *) mod_access overhaul:
10716 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
10717 and cidr syntax (i.e. 10.1.0.0/16). PR#762
10718 - Critical path was sped up by pre-computing a few things at config time.
10719 - The undocumented syntax "allow user-agents" was removed,
10720 the replacement is "allow from env=foobar" combined with mod_browser.
10721 - When used with hostnames it now forces a double-reverse lookup
10722 no matter what the directory settings are. This double-reverse
10723 doesn't affect any of the other routines that use the remote
10724 hostname. In particular it's still passed to CGIs and the log
10725 without the double-reverse check. Related PR#860.
10728 *) When a large bwrite() occurs (larger than the internal buffer size),
10729 while there is already something in the buffer, apache will combine
10730 the large write and the buffer into a single writev(). (This is
10731 in anticipation of using mmap() for reading files.)
10734 *) In obscure cases where a partial socket write occurred while chunking,
10735 Apache would omit the chunk header/footer on the next block. Cleaned
10736 up other bugs/inconsistencies in error conditions in buff.c. Fixed
10737 a bug where a long pause in DNS lookups could cause the last packet
10738 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
10740 *) API: Added child_exit function to module structure. This is called
10741 once per "heavy-weight process" just before a server child exit()'s
10742 e.g. when max_requests_per_child is reached, etc.
10743 [Doug MacEachern, Dean Gaudet]
10745 *) mod_include cleanup showed that handle_else was being used to handle
10746 endif. It didn't cause problems, but it was cleaned up too.
10749 *) mod_cern_meta would attempt to find meta files for the directory itself
10750 in some cases, but not in others. It now avoids it in all cases.
10753 *) mod_mime_magic would core dump if there was a decompression error.
10754 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
10756 *) PORT: some variants of DGUX require -lsocket -lnsl
10757 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
10759 *) mod_autoindex now allows sorting of FancyIndexed directory listings
10760 by the various fields (name, size, et cetera), either in ascending
10761 or descending order. Just click on the column header. [Ken Coar]
10763 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
10764 CPUs like the Alpha. Apache still stores ints in pointers, but that's
10765 the relatively safe direction. [Dean Gaudet] PR#344
10767 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
10768 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
10770 *) child_main avoids an unneeded call to select() when there is only one
10771 listening socket. [Dean Gaudet]
10773 *) In the event that the server is starved for idle servers it will
10774 spawn 1, then 2, then 4, ..., then 32 servers each second,
10775 doubling each second. It'll also give a warning in the errorlog
10776 since the most common reason for this is a poor StartServers
10777 setting. The define MAX_SPAWN_RATE can be used to raise/lower
10778 the maximum. [Dean Gaudet]
10780 *) Apache now provides an effectively unbuffered connection for
10781 CGI scripts. This means that data will be sent to the client
10782 as soon as the CGI pauses or stops output; previously, Apache would
10783 buffer the output up to a fixed buffer size before sending, which
10784 could result in the user viewing an empty page until the CGI finished
10785 or output a complete buffer. It is no longer necessary to use an
10786 "nph-" CGI to get unbuffered output. Given that most CGIs are written
10787 in a language that by default does buffering (e.g. perl) this
10788 shouldn't have a detrimental effect on performance.
10790 "nph-" CGIs, which formerly provided a direct socket to the client
10791 without any server post-processing, were not fully compatible with
10792 HTTP/1.1 or SSL support. As such they would have had to implement
10793 the transport details, such as encryption or chunking, in order
10794 to work properly in certain situations. Now, the only difference
10795 between nph and non-nph scripts is "non-parsed headers".
10796 [Dean Gaudet, Sameer Parekh, Roy Fielding]
10798 *) If a BUFF is switched from buffered to unbuffered reading the first
10799 bread() will return whatever remained in the buffer prior to the
10800 switch. [Dean Gaudet]
10802 Changes with Apache 1.3a1
10804 *) Added another Configure helper script: TestLib. It determines
10805 if a specified library exists. [Jim Jagielski]
10807 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
10808 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
10811 *) PORT: Some architectures use size_t for various lengths in network
10812 functions such as accept(), and getsockname(). The definition
10813 NET_SIZE_T is used to control this. [Dean Gaudet]
10815 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
10816 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
10817 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
10819 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
10820 [Igor N Kovalenko <infoh@mail.wplus.net>]
10822 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
10823 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
10824 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
10825 [Dean Gaudet] related PR#875
10827 *) API: Correct child_init() slot declaration from int to void, to
10828 match the init() declaration. Update mod_example to use the new
10831 *) added transport handle slot (t_handle) to the BUFF structure
10834 *) get_client_block() returns wrong length if policy is
10835 REQUEST_CHUNKED_DECHUNK.
10836 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
10838 *) Support the image map format of FrontPage. For example:
10839 rect /url.hrm 10 20 30 40
10840 ["Chris O'Byrne" <obyrne@iol.ie>] PR#807
10842 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
10843 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
10845 *) AddModuleInfo directive for mod_info which allows you to annotate
10846 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
10848 *) Added NoProxy directive to avoid using ProxyRemote for selected
10849 addresses. Added ProxyDomain directive to cause unqualified
10850 names to be qualified by redirection.
10851 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
10853 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
10854 header to the remote host in the proxy. [Sameer Parekh and
10857 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
10858 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
10859 URLs, fixed rewritelog(), fixed forced response code handling on
10860 redirects from within .htaccess files, disabled pipe locking under
10861 braindead SunOS 4.1.x, allow env variables to be set even on rules with
10862 no substitution, bugfixed situations where HostnameLookups is off, made
10863 mod_rewrite more thread-safe for NT port and fixed problem when creating
10864 an empty query string via "xxx?".
10865 This update also removes the copyright of Ralf S. Engelschall,
10866 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
10867 exclusively copyrighted by the Apache Group now. This happened because
10868 the author now has gifted mod_rewrite exclusively to the Apache Group and
10869 no longer maintains an external version.
10870 [Ralf S. Engelschall]
10872 *) API: Added child_init function to module structure. This is called
10873 once per "heavy-weight process" before any requests are handled.
10874 See http_config.h for more details. [Dean Gaudet]
10876 *) Anonymous_LogEmail was logging on each subrequest.
10877 [Dean Gaudet] PR#421, 868
10879 *) API: Added is_initial_req() which tests if the request being
10880 processed is the initial request, or a subrequest.
10883 *) Extended SSI (mod_include) now handles additional relops for
10884 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
10886 *) Configure fixed to correctly propagate user-selected options and
10887 settings (such as CC and OPTIM) to Makefiles other than
10888 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
10890 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
10891 directory indices to start with the contents of the HeaderName file
10892 if there is one. If there isn't one, the behaviour is unchanged.
10893 [Ken Coar, Roy Fielding, Andrey A. Chernov]
10895 *) WIN32: Modules can now be dynamically loaded DLLs using the
10896 LoadModule/LoadFile directives. Note that module DLLs must be
10897 compiled with the multithreaded DLL version of the runtime library.
10898 [Alexei Kosut and Ben Laurie]
10900 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
10901 This allows the admin to completely remove automatic indexing
10902 from the server, while still supporting the basic functions of
10903 trailing-slash redirects and DirectoryIndex files. Note that if
10904 you're carrying over an old Configuration file and you use directory
10905 indexing then you'll want to add:
10907 Module autoindex_module mod_autoindex.o
10909 before mod_dir in your Configuration. [Dean Gaudet]
10911 *) popendir/pclosedir created to properly protect directory scanning.
10912 [Dean Gaudet] PR#525
10914 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
10915 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
10916 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
10919 *) The AccessFileName directive can now take more than one filename.
10920 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
10922 *) The new mod_mime_magic can be used to "magically" determine the type
10923 of a file if the extension is unknown. Based on the unix file(1)
10924 command. [Ian Kluft <ikluft@cisco.com>]
10926 *) We now determine and display the time spent processing a
10927 request if desired. [Jim Jagielski]
10929 *) mod_status: PID field of "dead" child slots no longer displays
10930 main httpd process's PID. [Jim Jagielski]
10932 *) Makefile.nt added - to build all the bits from the command line:
10933 nmake -f Makefile.nt
10934 Doesn't yet work properly. [Ben Laurie]
10936 *) Default text of 404 error is now "Not Found" rather than the
10937 potentially misleading "File Not Found". [Ken Coar]
10939 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
10940 for the net if we require people that actually need this data to
10941 enable it. [Linus Torvalds]
10943 *) directory_walk() is an expensive function, keep a little more state to
10944 avoid needless string counting. Add two new functions make_dirstr_parent
10945 and make_dirstr_prefix which replace all existing uses of make_dirstr.
10946 The new functions are a little less general than make_dirstr, but
10947 work more efficiently (less memory, less string counting).
10950 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
10951 to LDFLAGS) to avoid complications with lex rules in make files.
10952 [Dean Gaudet] PR#372
10954 *) run_method optimized to avoid needless scanning over NULLs in the
10955 module list. [Dean Gaudet]
10957 *) Revamp of (unix) scoreboard management code such that it avoids
10958 unnecessary traversals of the scoreboard on each hit. This is
10959 particularly important for high volume sites with a large
10960 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
10961 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
10962 httpd.h. [Dean Gaudet]
10964 *) In configurations using multiple Listen statements it was possible for
10965 busy sockets to starve other sockets of service. [Dean Gaudet]
10967 *) Added hook so standalone_main can be replaced at compile time
10968 (define STANDALONE_MAIN)
10971 *) Lowest-level read/write functions in buff.c will be replaced with
10972 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
10973 compile time. The default sfio discipline will behave as apache
10974 would without sfio compiled in.
10977 *) Enhance UserDir directive (mod_userdir) to accept a list of
10978 usernames for the 'disable' keyword, and add 'enable user...' to
10979 selectively *en*able userdirs if they're globally disabled.
10982 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
10983 will work with Netscape dbm files. (dbmmanage will probably not
10984 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
10986 *) Add a ListenBacklog directive to control the backlog parameter
10987 passed to listen(). Also change the default to 511 from 512.
10990 *) API: A new handler response DONE which informs apache that the
10991 request has been handled and it can finish off quickly, similar to
10992 how it handles errors. [Rob Hartill]
10994 *) Turn off chunked encoding after sending terminating chunk/footer
10995 so that we can't do it twice by accident. [Roy Fielding]
10997 *) mod_expire also issues Cache-Control: max-age headers.
11000 *) API: Added kill_only_once option for free_proc_chain so that it won't
11001 aggressively try to kill off specific children. For fastcgi.
11002 [Stanley Gambarin <gambarin@OpenMarket.com>]
11004 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
11006 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
11007 When used together, these cause mod_dir to emit HEIGHT and WIDTH
11008 attributes in the FancyIndexing IMG tags. [Ken Coar]
11010 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
11012 *) PORT: Added Windows NT support
11013 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
11015 Changes with Apache 1.2.6
11017 *) mod_include when using XBitHack Full would send ETags in addition to
11018 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
11019 [Dean Gaudet] PR#1133
11021 *) SECURITY: When a client connects to a particular port/addr, and
11022 gives a Host: header ensure that the virtual host requested can
11023 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
11025 *) Support virtual hosts with wildcard port and/or multiple ports
11026 properly. [Ed Korthof <ed@organic.com>]
11028 *) Fixed some case-sensitivity issues according to RFC2068.
11031 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
11032 and mod_include.c. [Dean Gaudet]
11034 *) Variable 'cwd' was being used pointlessly before being set.
11037 *) SIGURG doesn't exist on all platforms.
11038 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
11040 *) When an error occurs during a POST, or other operation with a
11041 request body, the body has to be read from the net before allowing
11042 a keepalive session to continue. [Roy Fielding] PR#1399
11044 *) When an error occurs in fcntl() locking suggest the user look up
11045 the docs for LockFile. [Dean Gaudet]
11047 *) table_set() and table_unset() did not deal correctly with
11048 multiple occurrences of the same key. [Stephen Scheck
11049 <sscheck@infonex.net>, Ben Laurie] PR#1604
11051 *) send_fd_length() did not calculate total_bytes_sent properly in error
11052 cases. [Ben Reser <breser@regnow.com>] PR#1366
11054 *) r->connection->user was allocated in the wrong pool causing corruption
11055 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
11057 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
11058 Also removed the auto-generated link to www.apache.org that was the
11059 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
11061 *) Multiple "close" tokens may have been set in the "Connection"
11062 header, not an error, but a waste.
11063 [Ronald.Tschalaer@psi.ch] PR#1683
11065 *) "basic" and "digest" auth tokens should be tested case-insensitive.
11066 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
11068 *) It appears the "257th byte" bug (see
11069 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
11070 at the 256th byte as well. Fixed. [Dean Gaudet]
11072 *) mod_rewrite would not handle %3f properly in some situations.
11075 *) Apache could generate improperly chunked HTTP/1.1 responses when
11076 the bputc() or rputc() functions were used by modules (such as
11077 mod_include). [Dean Gaudet]
11079 *) #ifdef wrap a few #defines in httpd.h to make life easier on
11080 some ports. [Ralf Engelschall]
11082 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
11084 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
11086 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
11088 Changes with Apache 1.2.5
11090 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
11091 only an issue on systems without a MAXDNAME define or where
11092 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
11094 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
11097 *) Fix core dump in the ftp proxy when reading incorrectly formatted
11098 directory listings. [Marc Slemko]
11100 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
11103 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
11104 is used to read various types of files such as htaccess and
11105 htpasswd files. [Marc Slemko]
11107 *) SECURITY: Ensure that the buffer returned by ht_time is always
11108 properly null terminated. [Marc Slemko]
11110 *) SECURITY: General mod_include cleanup, including fixing several
11111 possible buffer overflows and a possible infinite loop. This cleanup
11112 was done against 1.3 code and then backported to 1.2, the result
11113 is a large difference (due to indentation cleanup in 1.3 code).
11114 Users interested in seeing a smaller set of relevant differences
11115 should consider comparing against src/modules/standard/mod_include.c
11116 from the 1.3b3 release. Non-indentation changes to mod_include
11117 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
11119 *) SECURITY: Numerous changes to mod_imap in a general cleanup
11120 including fixing a possible buffer overflow. This cleanup also
11121 was done with 1.3 code as a basis, see the the previous note
11122 about mod_include. [Dean Gaudet]
11124 *) SECURITY: If a htaccess file can not be read due to bad
11125 permissions, deny access to the directory with a HTTP_FORBIDDEN.
11126 The previous behavior was to ignore the htaccess file if it could not
11127 be read. This change may make some setups with unreadable
11128 htaccess files stop working. PR#817 [Marc Slemko]
11130 *) SECURITY: no2slash() was O(n^2) in the length of the input.
11131 Make it O(n). This inefficiency could be used to mount a denial
11132 of service attack against the Apache server. Thanks to
11133 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
11134 this. [Dean Gaudet]
11136 *) mod_include used uninitialized data for some uses of && and ||.
11137 [Brian Slesinsky <bslesins@wired.com>] PR#1139
11139 *) mod_imap should decline all non-GET methods.
11140 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
11142 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
11144 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
11145 r->filename. Since those two are meant to be in sync with each other
11146 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
11148 *) mod_include did not properly handle all possible redirects from sub-
11149 requests. [Ken Coar]
11151 *) Inetd mode (which is buggy) uses timeouts without having setup the
11152 jmpbuffer. [Dean Gaudet] PR#1064
11154 *) Work around problem under Linux where a child will start looping
11155 reporting a select error over and over.
11156 [Rick Franchuk <rickf@transpect.net>] PR#1107
11158 Changes with Apache 1.2.4
11160 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
11161 always making requests with the full-URI instead of just the URI path.
11162 [Marc Slemko, Roy Fielding]
11164 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
11165 on this platform. [Marc Slemko]
11167 Changes with Apache 1.2.3
11169 *) The request to a remote proxy was mangled if it was generated as the
11170 result of a ProxyPass directive. URL schemes other than http:// were not
11171 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
11172 PR#812 [Lars Eilebrecht]
11174 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11175 information for case where proxy module is not available. [Marc Slemko]
11177 *) Force proxy to always respond as HTTP/1.0, which it was failing to
11178 do for errors and cached responses. [Roy Fielding]
11180 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
11182 Changes with Apache 1.2.2 [not released]
11184 *) Fixed another long-standing bug in sub_req_lookup_file where it would
11185 happily skip past access checks on subdirectories looked up with relative
11186 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
11189 *) Add lockfile name to error message printed out when
11190 USE_FLOCK_SERIALIZED_ACCEPT is defined.
11193 *) Enhanced the chunking and error handling inside the buffer functions.
11194 [Dean Gaudet, Roy Fielding]
11196 *) When merging the main server's <Directory> and <Location> sections into
11197 a vhost, put the main server's first and the vhost's second. Otherwise
11198 the vhost can't override the main server. [Dean Gaudet] PR#717
11200 *) The <Directory> code would merge and re-merge the same section after
11201 a match was found, possibly causing problems with some modules.
11204 *) Fixed an infinite loop in mod_imap for references above the server root.
11205 [Dean Gaudet] PR#748
11207 *) mod_include cleanup showed that handle_else was being used to handle
11208 endif. It didn't cause problems, but it was cleaned up too.
11211 *) Last official synchronization of mod_rewrite with author version (because
11212 mod_rewrite is now directly developed by the author at the Apache Group):
11213 o added diff between mod_rewrite 3.0.6+ and 3.0.9
11214 minus WIN32/NT stuff, but plus copyright removement.
11216 - workaround for detecting infinite rewriting loops
11217 - fixed setting of env vars when "-" is used as subst string
11218 - fixed forced response code on redirects (PR#777)
11219 - fixed cases where r->args is ""
11220 - kludge to disable locking on pipes under braindead SunOS
11221 - fix for rewritelog in cases where remote hostname is unknown
11222 - fixed totally damaged request_rec walk-back loop
11223 o remove static from local data and add static to global ones.
11224 o replaced ugly proxy finding stuff by simple
11225 find_linked_module("mod_proxy") call.
11226 o added missing negation char on rewritelog()
11227 o fixed a few comment typos
11228 [Ralf S. Engelschall]
11230 *) Anonymous_LogEmail was logging on each subrequest.
11231 [Dean Gaudet] PR#421, PR#868
11233 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11234 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11235 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11236 Additionally mod_browser now triggers during translate_name to workaround
11237 a deficiency in the header_parse phase.
11238 [Dean Gaudet] PR#875
11240 *) get_client_block() returns wrong length if policy is
11241 REQUEST_CHUNKED_DECHUNK.
11242 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
11244 *) Properly treat <files> container like other containers in mod_info.
11245 [Marc Slemko] PR#848
11247 *) The proxy didn't treat the "Host:" keyword of the host header as case-
11248 insensitive. The proxy would corrupt the first line of a response from
11249 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
11251 *) mod_include would log some bogus values occasionally.
11252 [Skip Montanaro <skip@calendar.com>, Marc Slemko] PR#797
11254 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
11255 under Solaris 2.x (up through 2.5.1). It has been fixed.
11256 [Dean Gaudet] PR#832
11258 *) API: In HTTP/1.1, whether or not a request message contains a body
11259 is independent of the request method and based solely on the presence
11260 of a Content-Length or Transfer-Encoding. Therefore, our default
11261 handlers need to be prepared to read a body even if they don't know
11262 what to do with it; otherwise, the body would be mistaken for the
11263 next request on a persistent connection. discard_request_body()
11264 has been added to take care of that. [Roy Fielding] PR#378
11266 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
11267 release version number, such that it always increases along the
11268 same lines as our source code branching. [Roy Fielding]
11270 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
11272 Changes with Apache 1.2.1
11274 *) SECURITY: Don't serve file system objects unless they are plain files,
11275 symlinks, or directories. This prevents local users from using pipes
11276 or named sockets to invoke programs for an extremely crude form of
11279 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
11280 could contain "../" allowing a local user to "publish" any file on
11281 the system. No slashes are allowed now. [Dean Gaudet]
11283 *) SECURITY: It was possible to violate the symlink Options using mod_dir
11284 (headers, readmes, titles), mod_negotiation (type maps), or
11285 mod_cern_meta (meta files). [Dean Gaudet]
11287 *) SECURITY: Apache will refuse to run as "User root" unless
11288 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
11290 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
11291 if it contained a .htaccess disallowing symlinks. This is contrary
11292 to the rule that symlink permissions are tested with the symlink
11293 options of the parent directory. [Dean Gaudet] PR#353
11295 *) CONFIG: The LockFile directive can be used to place the serializing
11296 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
11297 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
11300 *) Request processing now retains state of whether or not the request
11301 body has been read, so that internal redirects and subrequests will
11302 not try to read it twice (and block). [Roy Fielding]
11304 *) Add a placeholder in modules/Makefile to avoid errors with certain
11305 makes. [Marc Slemko]
11307 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
11308 [Dean Gaudet] PR#644
11310 *) mod_include was not properly changing the current directory.
11311 [Marc Slemko] PR#742
11313 *) Attempt to work around problems with third party libraries that do not
11314 handle high numbered descriptors (examples include bind, and
11315 solaris libc). On all systems apache attempts to keep all permanent
11316 descriptors above 15 (called the low slack line). Solaris users
11317 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
11318 which keeps all non-FILE * descriptors above 255. On all systems
11319 this should make supporting large numbers of vhosts with many open
11320 log files more feasible. If this causes trouble please report it,
11321 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
11322 [Dean Gaudet] various PRs
11324 *) Related to the last entry, network sockets are now opened before
11325 log files are opened. The only known case where this can cause
11326 problems is under Solaris with many virtualhosts and many Listen
11327 directives. But using -DHIGH_SLACK_LINE=256 described above will
11328 work around this problem. [Dean Gaudet]
11330 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
11333 *) Improved unix error response logging. [Marc Slemko]
11335 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
11336 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
11337 when a URL http://... was used in conjunction with a special
11338 redirect flag, e.g. R=permanent, the permanent status was lost.
11339 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>, Ralf S. Engelschall]
11341 *) If an object has multiple variants that are otherwise equal Apache
11342 would prefer the last listed variant rather than the first.
11343 [Paul Sutton] PR#94
11345 *) "make clean" at the top level now removes *.o. [Dean Gaudet] PR#752
11347 *) mod_status dumps core in inetd mode. [Marc Slemko and Roy Fielding]
11350 *) pregsub had an off-by-1 in its error checking code. [Alexei Kosut]

11373 Changes with Apache 1.2
11375 Changes with Apache 1.2b11
11377 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
11379 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
11380 [Doug MacEachern, Rob Hartill]
11382 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
11383 reading from one buffer and writing to another, at least until it has
11384 a custom timeout handler. [Roy Fielding and Petr Lampa]
11386 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
11387 apparently due to a mismatch between sigaction and setjmp.
11388 [Roy Fielding] PR#502
11390 *) Log correct status code if we timeout before receiving a request (408)
11391 or if we received a request-line that was too long to process (414).
11392 [Ed Korthof and Roy Fielding] PR#601
11394 *) Virtual hosts with the same ServerName, but on different ports, were
11395 not being selected properly. [Ed Korthof]
11397 *) Added code to return the requested IP address from proxy_host2addr()
11398 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
11399 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
11400 [Chuck Murcko] PR#614
11402 *) If multiple requests on a single connection are used to retrieve
11403 data from different virtual hosts, the virtual host list would be
11404 scanned starting with the most recently used VH instead of the first,
11405 causing most virtual hosts to be ignored.
11406 [Paul Sutton and Martin Mares] PR#610
11408 *) The OS/2 handling of process group was broken by a porting patch for
11409 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
11411 *) Inherit virtual server port from main server if none (or "*") is
11412 given for VirtualHost. [Dean Gaudet] PR#576
11414 *) If the lookup for a DirectoryIndex name with content negotiation
11415 has found matching variants, but none are acceptable, return the
11416 negotiation result if there are no more DirectoryIndex names to lookup.
11417 [Petr Lampa and Roy Fielding]
11419 *) If a soft_timeout occurs after keepalive is set, then the main child
11420 loop would try to read another request even though the connection
11421 has been aborted. [Roy Fielding]
11423 *) Configure changes: Allow for whitespace at the start of a
11424 Module declaration. Also, be more understanding about the
11425 CC=/OPTIM= format in Configuration. Finally, fix compiler
11426 flags if using HP-UX's cc compiler. [Jim Jagielski]
11428 *) Subrequests and internal redirects now inherit the_request from the
11429 original request-line. [Roy Fielding]
11431 *) Test for error conditions before creating output header fields, since
11432 we don't want the error message to include those fields. Likewise,
11433 reset the content_language(s) and content_encoding of the response
11434 before generating or redirecting to an error message, since the new
11435 message will have its own Content-* definitions. [Dean Gaudet]
11437 *) Restored the semantics of headers_out (headers sent only with 200..299
11438 and 304 responses) and err_headers_out (headers sent with all responses).
11439 Avoid the overhead of copying tables if err_headers_out is empty
11440 (the usual case). [Roy Fielding]
11442 *) Fixed a couple places where a check for the default Content-Type was
11443 not properly checking both the value configured by the DefaultType
11444 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
11445 of DEFAULT_TYPE to match the documented default (text/plain).
11446 [Dean Gaudet] PR#506
11448 *) Escape the HTML-sensitive characters in the Request-URI that is
11449 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
11451 *) Properly initialize the flock structures used by the mutex locking
11452 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
11455 *) The method for determining PATH_INFO has been restored to the pre-1.2b
11456 (and NCSA httpd) definition wherein it was the extra path info beyond
11457 the CGI script filename. The environment variable FILEPATH_INFO has
11458 been removed, and instead we supply the original REQUEST_URI to any
11459 script that wants to be Apache-specific and needs the real URI path.
11460 This solves a problem with existing scripts that use extra path info
11461 in the ScriptAlias directive to pass options to the CGI script.
11464 *) The _default_ change in 1.2b10 will change the behaviour on configs
11465 that use multiple Listen statements for listening on multiple ports.
11466 But that change is necessary to make _default_ consistent with other
11467 forms of <VirtualHost>. It requires such configs to be modified
11468 to use <VirtualHost _default_:*>. The documentation has been
11469 updated. [Dean Gaudet] PR#530
11471 *) If an ErrorDocument CGI script is used to respond to an error
11472 generated by another CGI script which has already read the message
11473 body of the request, the server would block trying to read the
11474 message body again. [Rob Hartill]
11476 *) signal() replacement conflicted with a define on QNX (and potentially
11477 other platforms). Fixed. [Ben Laurie] PR#512
11479 Changes with Apache 1.2b10
11481 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
11482 to be configured via -D in Configuration. [Dean Gaudet] PR#449
11484 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
11486 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
11488 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
11489 config, in case the hostent struct returned is trash.
11490 [Chuck Murcko] PR #491
11492 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
11493 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
11495 Changes with Apache 1.2b9 [never announced]
11497 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
11498 changes and in anticipation of 1.2 final release. [Roy Fielding]
11500 *) Fix problem with scripts not receiving a SIGPIPE when client drops
11501 the connection (e.g., when user presses Stop). Apache will now stop
11502 trying to send a message body immediately after an error from write.
11503 [Roy Fielding and Nathan Kurz] PR#335
11505 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
11506 than mod_alias, and mod_alias has higher priority than mod_proxy;
11507 rearranged other modules to enhance understanding of their purpose
11508 and relative order (and maybe even reduce some overhead).
11509 [Roy Fielding and Sameer Parekh]
11511 *) Fix graceful restart. Eliminate many signal-related race
11512 conditions in both forms of restart, and in SIGTERM. See
11513 htdocs/manual/stopping.html for details on stopping and
11514 restarting the parent. [Dean Gaudet]
11516 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
11517 memory allocator to avoid a behaviour that required extra blocks to
11518 be allocated. [Dean Gaudet]
11520 *) Allow suexec to access files relative to current directory but not
11521 above. (Excluding leading / or any .. directory.) [Ken Coar]
11524 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
11525 PR#367, 368, 354, 453
11527 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
11528 while obtaining the /~user and save the username in a separate data
11529 area so that it won't be overwritten by the call to getgrgid(), and
11530 fix some misuse of the pool string allocation functions. Also fixes
11531 a general problem with parsing URL query info into args for CGI scripts.
11532 [Roy Fielding] PR#339, 367, 354, 453
11534 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
11536 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
11538 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
11539 AuthDBAuthoritative. [Marc Slemko] PR#420
11541 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
11543 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
11544 object that can't be PUT, or FOOBAR for some method FOOBAR that
11545 apache doesn't know about at all). Log 404s that occur in mod_include.
11546 [Paul Sutton, John Van Essen]
11548 *) If a soft timeout (or lingerout) occurs while trying to flush a
11549 buffer or write inside buff.c or fread'ing from a CGI's output,
11550 then the timeout would be ignored. [Roy Fielding] PR#373
11552 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
11553 parsing of headers. If the terminating empty-line CRLF occurs starting
11554 at the 256th or 257th byte of output, then Navigator will think a normal
11555 image is invalid. We are guessing that this is because their initial
11556 read of a new request uses a 256 byte buffer. We check the bytes written
11557 so far and, if we are about to tickle the bug, we instead insert a
11558 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
11560 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
11561 of an external redirection. [Roy Fielding and Paul Sutton]
11563 *) Configure would create a broken Makefile if the configuration file
11564 contained a commented-out Rule. [Roy Fielding]
11566 *) Promote per_dir_config and subprocess_env from the subrequest to the
11567 main request in mod_negotiation. In particular this fixes a bug
11568 where <Files> sections wouldn't properly apply to negotiated content.
11571 *) Fix a potential deadlock in mod_cgi script_err handling.
11572 [Ralf S. Engelschall]
11574 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
11575 [Mitchell Blank Jr]
11577 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
11578 .htaccess files because the RewriteBase was not replaced correctly.
11579 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
11580 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
11582 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
11583 1.x the settings are those of pre-1.2b8. For 2.x we include
11584 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
11585 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
11586 [Dean Gaudet] PR#336, PR#340
11588 *) Redirect did not preserve ?query_strings when present in the client's
11589 request. [Dean Gaudet]
11591 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
11593 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
11595 *) Add UnixWare compile/install instructions. [Chuck Murcko]
11597 *) Add mod_example (illustration of API techniques). [Ken Coar]
11599 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
11601 *) Improve handling of directories when filenames have spaces in them.
11604 *) For hosts with multiple IP addresses, try all additional addresses if
11605 necessary to get a connect. Fail only if hostent address list is
11606 exhausted. [Chuck Murcko]
11608 *) More signed/unsigned port fixes. [Dean Gaudet]
11610 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
11613 Changes with Apache 1.2b8
11615 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
11616 to it. [Marc Slemko]
11618 *) The addition of <Location> and <File> directives made the
11619 sub_req_lookup_simple() function bogus, so we now handle
11620 the special cases directly. [Dean Gaudet]
11622 *) We now try to log where the server is dumping core when a fatal
11623 signal is received. [Ken Coar]
11625 *) Improved lingering_close by adding a special timeout, removing the
11626 spurious log messages, removing the nonblocking settings (they
11627 are not needed with the better timeout), and adding commentary
11628 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
11629 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
11631 *) Send error messages about setsockopt failures to the server error
11632 log instead of stderr. [Roy Fielding]
11634 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
11636 *) Stopgap solution for CGI 3-second delay with server-side includes: if
11637 processing a subrequest, allocate memory from r->main->pool instead
11638 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
11639 in the middle of an SSI request. [Dean Gaudet] PR #122
11641 *) Fixed status of response when POST is received for a nonexistent URL
11642 (was sending 405, now 404) and when any method is sent with a
11643 full-URI that doesn't match the server and the server is not acting
11644 as a proxy (was sending 501, now 403). [Roy Fielding]
11646 *) Host port changed to unsigned short. [Ken Coar] PR #276
11648 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
11650 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
11652 *) Report extra info from errno with many errors that cause httpd to exit.
11653 spawn_child, popenf, and pclosef now have valid errno returns in the
11654 event of an error. Correct problems where errno was stomped on
11655 before being reported. [Dean Gaudet]
11657 *) In the proxy, if the cache filesystem was full, garbage_coll() was
11658 never called, and thus the filesystem would remain full indefinitely.
11659 We now also remove incomplete cache files left if the origin server
11660 didn't send a Content-Length header and either the client has aborted
11661 transfer or bwrite() to client has failed. [Petr Lampa]
11663 *) Fixed the handling of module and script-added header fields.
11664 Improved the interface for sending header fields and reduced
11665 the duplication of code between sending okay responses and errors.
11666 We now always send both headers_out and err_headers_out, and
11667 ensure that the server-reserved fields are not being overridden,
11668 while not overriding those that are not reserved. [Roy Fielding]
11670 *) Moved transparent content negotiation fields to err_headers_out
11671 to reflect above changes. [Petr Lampa]
11673 *) Fixed the determination of whether or not we should make the
11674 connection persistent for all of the cases where some other part
11675 of the server has already indicated that we should not. Also
11676 improved the ordering of the test so that chunked encoding will
11677 be set whenever it is desired instead of only when KeepAlive
11678 is enabled. Added persistent connection capability for most error
11679 responses (those that do not indicate a bad input stream) when
11680 accessed by an HTTP/1.1 client. [Roy Fielding]
11682 *) Added missing timeouts for sending header fields, error responses,
11683 and the last chunk of chunked encoding, each of which could have
11684 resulted in a process being stuck in write forever. Using soft_timeout
11685 requires that the sender check for an aborted connection rather than
11686 continuing after an EINTR. Timeouts that used to be initiated before
11687 send_http_header (and never killed) are now initiated only within or
11688 around the routines that actually do the sending, and not allowed to
11689 propagate above the caller. [Roy Fielding]
11691 *) mod_auth_anon required an @ or a . in the email address, not both.
11694 *) per_dir_defaults weren't set correctly until directory_walk for
11695 name-based vhosts. This fixes an obscure bug with the wrong config
11696 info being used for vhosts that share the same ip as the server.
11699 *) Improved generation of modules/Makefile to be more generic for
11700 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
11702 *) Generate makefile dependency for Configuration based on the actual
11703 name given when running the Configure process. [Dean Gaudet]
11705 *) Fixed problem with vhost error log not being set prior to
11706 initializing virtual hosts. [Dean Gaudet]
11708 *) Fixed infinite loop when a trailing slash is included after a type map
11709 file URL (extra path info). [Petr Lampa]
11711 *) Fixed server status updating of per-connection counters. [Roy Fielding]
11713 *) Add documentation for DNS issues (reliability and security), and try
11714 to explain the virtual host matching process. [Dean Gaudet]
11716 *) Try to continue gracefully by disabling the vhost if a DNS lookup
11717 fails while parsing the configuration file. [Dean Gaudet]
11719 *) Improved calls to setsockopt. [Roy Fielding]
11721 *) Negotiation changes: Don't output empty content-type in variant list;
11722 Output charset in variant list; Return sooner from handle_multi() if
11723 no variants found; Add handling of '*' wildcard in Accept-Charset.
11724 [Petr Lampa and Paul Sutton]
11726 *) Fixed overlaying of request/sub-request notes and headers in
11727 mod_negotiation. [Dean Gaudet]
11729 *) If two variants' charset quality are equal and one is the default
11730 charset (iso-8859-1), then prefer the variant that was specifically
11731 listed in Accept-Charset instead of the default. [Petr Lampa]
11733 *) Memory allocation problem in push_array() -- it would corrupt memory
11734 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
11736 *) invoke_handler() doesn't handle mime arguments in content-type
11737 [Petr Lampa] PR#160
11739 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
11742 *) Fixed problem with ErrorDocument not working for virtual hosts
11743 due to one of the performance changes in 1.2b7. [Dean Gaudet]
11745 *) Log an error message if we get a request header that is too long,
11746 since it may indicate a buffer overflow attack. [Marc Slemko]
11748 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
11749 not reject URLs without a double-slash, as per RFC2068 section 3.2.
11750 [Ken Coar] PR #146, #187
11752 *) Added table entry placeholder for new header_parser callback
11753 in all of the distributed modules. [Ken Coar] PR #191
11755 *) Allow for cgi files without the .EXE extension on them under OS/2.
11756 [Garey Smiley] PR #59
11758 *) Fixed error message when resource is not found and URL contains
11759 path info. [Petr Lampa and Dean Gaudet] PR #40
11761 *) Fixed user and server confusion over what should be a virtual host
11762 and what is the main server, resulting in access to something
11763 other than the name defined in the virtualhost directive (but
11764 with the same IP address) failing. [Dean Gaudet]
11766 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
11767 AIX; improves the redirection stuff to enable the users to generally
11768 redirect to http, https, gopher and ftp; added TIME variable for
11769 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
11770 special patterns >STRING, <STRING and =STRING to RewriteCond, which
11771 can be used in conjunction with %{TIME} or other variables to create
11772 time-dependent rewriting rules. [Ralf S. Engelschall]
11774 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
11775 Module authors may need to adjust their code for proper cleanup to take
11776 place (that is, call note_cleanups_for_fd()). This change fixes problems
11777 with file descriptors being erroneously closed when the proxy module was
11778 in use. [Ben Laurie]
11780 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
11781 initgroups() to hose the group information needed for later
11782 comparisons. [Randy Terbush]
11784 *) Remove unnecessary call to va_end() in create_argv() which
11785 caused a SEGV on some systems.
11787 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
11790 *) Clear memory allocated for listeners. [Randy Terbush]
11792 *) Improved handling of IP address as a virtualhost address and
11793 introduced "_default_" as a synonym for the default vhost config.
11794 [Dean Gaudet] PR #212
11796 Changes with Apache 1.2b7
11798 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
11800 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
11802 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
11803 - replace protocol response numbers with symbols
11804 - save variant-list into main request notes
11805 - free allocated memory from subrequests
11806 - merge notes, headers_out and err_headers_out
11808 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
11809 "HTTP/#.# ###*" to be more lenient about what we accept.
11812 *) more proxy FTP bug fixes:
11813 - Changed send_dir() to remove user/passwd from displayed URL.
11814 - Changed login error messages to be more descriptive.
11815 - remove setting of SO_DEBUG socket option
11816 - Make ftp_getrc() more lenient about multiline responses,
11817 specifically, 230 responses which don't have continuation 230-
11818 on each line). These seem to be all NT FTP servers, and while
11819 perhaps questionable, they appear to be legal by RFC 959.
11820 - Add missing kill_timeout() after transfer to user completes.
11823 *) Fixed problem where a busy server could hang when restarting
11824 after being sent a SIGHUP due to child processes not exiting.
11827 *) Modify mod_include escaping so a '\' only signifies an escaped
11828 character if the next character is one that needs
11829 escaping. [Ben Laurie]
11831 *) Eliminated possible infinite loop in mod_imap when relative URLs are
11832 used with a 'base' directive that does not have a '/' in it.
11833 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
11835 *) Reduced the default timeout from 1200 seconds to 300, and the
11836 one in the sample configfile from 400 to 300. [Marc Slemko]
11838 *) Stop vbprintf from crashing if given a NULL string pointer;
11839 print (null) instead. [Ken Coar]
11841 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
11842 [Marc Slemko and Roy Fielding]
11844 *) Fixed problem with mod_cgi-generated internal redirects trying to
11845 read the request message-body twice. [Archie Cobbs and Roy Fielding]
11847 *) Reduced timeout on lingering close, removed possibility of a blocked
11848 read causing the child to hang, and stopped logging of errors if
11849 the socket is not connected (reset by client). [Roy Fielding]
11851 *) Rearranged main child loop to remove duplication of code in
11852 select/accept and keep-alive requests, fixed several bugs regarding
11853 checking scoreboard_image for exit indication and failure to
11854 account for all success conditions and trap all error conditions,
11855 prevented multiple flushes before closing the socket; close the entire
11856 socket buffer instead of just one descriptor, prevent logging of
11857 EPROTO and ECONNABORTED on platforms where supported, and generally
11858 improved readability. [Roy Fielding]
11860 *) Extensive performance improvements. Cleaned up inefficient use of
11861 auto initializers, multiple is_matchexp calls on a static string,
11862 and excessive merging of response_code_strings. [Dean Gaudet]
11864 *) Added double-buffering to mod_include to improve performance on
11865 server-side includes. [Marc Slemko]
11867 *) Several fixes for suexec wrapper. [Randy Terbush]
11868 - Make wrapper work for files on NFS filesystem.
11869 - Fix portability problem of MAXPATHLEN.
11870 - Fix array overrun problem in clean_env().
11871 - Fix allocation of PATH environment variable
11873 *) Removed extraneous blank line is description of mod_status chars.
11876 *) Logging of errors from the call_exec routine simply went nowhere,
11877 since the logfile fd has been closed, so now we send them to stderr.
11878 [Harald T. Alvestrand]
11880 *) Fixed core dump when DocumentRoot is a CGI.
11881 [Ben Laurie, reported by geddis@tesserae.com]
11883 *) Fixed potential file descriptor leak in mod_asis; updated it and
11884 http_core to use pfopen/pfclose instead of fopen/fclose.
11885 [Randy Terbush and Roy Fielding]
11887 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
11888 as the DEC Alpha which is 64-bit but uses 32-bit ints.
11889 [Dean Gaudet and Ken Coar]
11891 *) Return a 302 response code to the client when sending a redirect
11892 due to a missing trailing '/' on a directory instead of a 301; now
11893 it is cacheable. [Markus Gyger]
11895 *) Fix condition where, if a bad directive occurs in .htaccess, and
11896 sub_request() goes first to this directory, then log_reason() will
11897 SIGSEGV because it doesn't have initialized r->per_dir_config.
11898 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
11900 *) Fix handling of lang_index in is_variant_better(). This was
11901 causing problems which resulted in the server sending the
11902 wrong language document in some cases. [Petr Lampa]
11904 *) Remove free() from clean_env() in suexec wrapper. This was nuking
11905 the clean environment on some systems.
11907 *) Tweak byteserving code (e.g. serving PDF files) to work around
11908 bugs in Netscape Navigator and Microsoft Internet Explorer.
11909 Emit Content-Length header when sending multipart/byteranges.
11912 *) Port to HI-UX/WE2. [Nick Maclaren]
11914 *) Port to HP MPE operating system for HP 3000 machines
11915 [Mark Bixby <markb@cccd.edu>]
11917 *) Fixed bug which caused a segmentation fault if only one argument
11918 given to RLimit* directives. [Ed Korthof]
11920 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
11922 *) Improved buffered output to the client by delaying the flush decision
11923 until the BUFF code is actually about to read the next request.
11924 This fixes a problem introduced in 1.2b5 with clients that send
11925 an extra CRLF after a POST request. Also improved chunked output
11926 performance by combining writes using writev() and removing as
11927 many bflush() calls as possible. NOTE: Platforms without writev()
11928 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
11929 or Configure, unless we have already done so. [Dean Gaudet]
11931 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
11933 *) Fixed mod_info output corruption bug introduced by buffer overflow
11934 fixes. [Dean Gaudet]
11936 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
11937 for the special case of a 304 response. [Paul Sutton]
11939 *) Improved handling of TRACE method by bypassing normal method handling
11940 and header parsing routines; fixed Allow response to always allow TRACE.
11943 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
11945 *) Cleaned-up some of the generated HTML. [Ken Coar]
11947 Changes with Apache 1.2b6
11949 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
11951 *) Fix typo introduced in fix for potential infinite loop around
11952 accept() in child_main(). This change caused the rev to 1.2b6.
11953 1.2b5 was never a public beta.
11955 Changes with Apache 1.2b5
11957 *) Change KeepAlive semantics (On|Off instead of a number), add
11958 MaxKeepAliveRequests directive. [Alexei Kosut]
11960 *) Various NeXT compilation patches, as well as a change in
11961 regex/regcomp.c since that file also used a NEXT define.
11964 *) Allow * to terminate the end of a directory match in mod_dir.
11965 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
11967 *) Don't call can_exec() if suexec_enabled. Calling this requires
11968 scripts executed by the suexec wrapper to be world executable, which
11969 defeats one of the advantages of running the wrapper. [Randy Terbush]
11971 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
11974 *) Migration from sprintf() to snprintf() to avoid buffer
11975 overflows. [Marc Slemko]
11977 *) Provide portable snprintf() implementation (ap_snprintf)
11978 as well as *cvt family. [Jim Jagielski]
11980 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
11983 *) Remove mod_fastcgi.c from the distribution. This module appears
11984 to be maintained more through the Open Market channels and should
11985 continue to be easily available at http://www.fastcgi.com/
11987 *) Fixed bug in modules/Makefile that wouldn't allow building in more
11988 than one subdirectory (or cleaning, either). [Jeremy Laidman]
11990 *) mod_info assumed that the config files were relative to ServerRoot.
11993 *) CGI scripts called as an error document resulting from failed
11994 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
11996 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
11999 *) Properly check errno to prevent display of a directory index
12000 when server receives a long enough URL to confuse stat().
12003 *) Several security enhancements to suexec wrapper. It is _highly_
12004 recommended that previously installed versions of the wrapper
12005 be replaced with this version. [Randy Terbush, Jason Dour]
12007 - ~user execution now properly restricted to ~user's home
12008 directory and below.
12009 - execution restricted to UID/GID > 100
12010 - restrict passed environment to known variables
12011 - call setgid() before initgroups() (portability fix)
12012 - remove use of setenv() (portability fix)
12014 *) Add HTTP/1.0 response forcing. [Ben Laurie]
12016 *) Add access control via environment variables. [Ben Laurie]
12018 *) Add rflush() function. [Alexei Kosut]
12020 *) remove duplicate pcalloc() call in new_connection().
12022 *) Fix incorrect comparison which could allow number of children =
12023 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
12024 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
12026 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
12027 AIX PS/2, CONVEXOS. [Jim Jagielski]
12029 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
12030 It's more portable. [Martin Kraemer]
12032 *) Replace references to make in Makefile.tmpl with $(MAKE).
12035 *) Add ProxyBlock directive w/IP address caching. Add IP address
12036 caching to NoCache directive as well. ProxyBlock works with all
12037 handlers; NoCache now also works with FTP for anonymous logins.
12038 Still more code cleanup. [Chuck Murcko]
12040 *) Add "header parse" API hook [Ben Laurie]
12042 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
12044 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
12046 *) Correctly allow access and auth directives in <Files> sections in
12047 server config files. [Alexei Kosut]
12049 *) Fix bug with ServerPath that could cause certain files to be not
12050 found by the server. [Alexei Kosut]
12052 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
12053 double-quote from text and so that it properly checks for unsupported
12054 status codes using the new index_of_response interface. [Roy Fielding]
12056 *) Multiple fixes to the lingering_close code in order to avoid being
12057 interrupted by a stray timeout, to avoid lingering on a connection
12058 that has already been aborted or never really existed, to ensure that
12059 we stop lingering as soon as any error condition is received, and to
12060 prevent being stuck indefinitely if the read blocks. Also improves
12061 reporting of error conditions. [Marc Slemko and Roy Fielding]
12063 *) Fixed initialization of parameter structure for sigaction.
12064 [mgyger@itr.ch, Adrian Filipi-Martin]
12066 *) Fixed reinitializing the parameters before each call to accept and
12067 select, and removed potential for infinite loop in accept.
12068 [Roy Fielding, after useful PR from adrian@virginia.edu]
12070 *) Fixed condition where, if a child fails to fork, the scoreboard would
12071 continue to say SERVER_STARTING forever. Eventually, the main process
12072 would refuse to start new children because count_idle_servers() will
12073 count those SERVER_STARTING entries and will always report that there
12074 are enough idle servers. [Phillip Vandry]
12076 *) Fixed bug in bcwrite regarding failure to account for partial writes.
12077 Avoided calling bflush() when the client is pipelining requests.
12078 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
12080 *) Added description of "." mode in server-status [Jim Jagielski]
12082 Changes with Apache 1.2b4
12084 *) Fix possible race condition in accept_mutex_init() that
12085 could leave a small security hole open allowing files to be
12086 overwritten in cases where the server UID has write permissions.
12089 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
12091 *) Fix portablity problem in util_script where ARG_MAX may not be
12092 defined for some systems.
12094 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
12097 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
12098 style magic #! token for better script portability. [Garey Smiley]
12100 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
12101 execution for ~userdir CGI. [Jason Dour]
12103 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
12105 *) Fix month off by one in suexec wrapper logging.
12107 Changes with Apache 1.2b3:
12109 *) Fix error in mod_cgi which could cause resources not to be properly
12110 freed, or worse. [Dean Gaudet]
12112 *) Fix find_string() NULL pointer dereference. [Howard Fear]
12114 *) Add set_flag_slot() at the request of Dirk and others.
12117 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
12119 *) Add changes to improve the error message given for invalid
12120 ServerName parameters. [Dirk vanGulik]
12122 *) Add "Authoritative" directive for Auth modules that don't
12123 currently have it. This gives admin control to assign authoritative
12124 control to an authentication scheme and allow "fall through" for
12125 those authentication modules that aren't "Authoritative" thereby
12126 allowing multiple authentication mechanisms to be chained.
12129 *) Remove requirement for ResourceConfig/AccessConfig if not using
12130 the three config file layout. [Randy Terbush]
12132 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
12134 *) Changes to suexec wrapper to fix the following problems:
12135 1. symlinked homedirs will kill ~userdirs.
12136 2. initgroups() on Linux 2.0.x clobbers gr->grid.
12137 3. CGI command lines paramters problems
12138 4. pw-pwdir for "docroot check" still the httpd user's pw record.
12139 [Randy Terbush, Jason Dour]
12141 *) Change create_argv() to accept variable arguments. This fixes
12142 a problem where arguments were not getting passed to the CGI via
12143 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
12145 *) Collapse multiple slashes in path URLs to properly apply
12146 handlers defined by <Location>. [Alexei Kosut]
12148 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
12150 *) Improve the accuracy of request duration timings by setting
12151 r->request_time in read_request_line() instead of read_request().
12154 *) Reset timeout while reading via get_client_block() in mod_cgi.c
12155 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
12157 *) Add the ability to pass different Makefile.tmpl files to Configure
12158 using the -make flag. [Rob Hartill]
12160 *) Fix coredump triggered when sending a SIGHUP to the server caused
12161 by an assertion failure, in turn caused by an uninitialised field in a
12165 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
12166 PATH_INFO from previous versions of Apache (in certain situations,
12167 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
12168 [later removed in 1.2b11]
12170 *) Add rwrite() function to API to allow for sending strings of
12171 arbitrary length. [Doug MacEachern]
12173 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
12175 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
12176 NeXT. [Jim Jagielski]
12178 *) Removed recent modification to promote the status code on internal
12179 redirects, since the correct fix was to change the default log format
12180 in mod_log_config so that it outputs the original status. [Rob Hartill]
12182 Changes with Apache 1.2b2:
12184 *) Update set_signals() to use sigaction() for setting handlers.
12185 This appears to fix a re-entrant problem in the seg_fault()
12186 bus_error() handlers. [Randy Terbush]
12188 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
12190 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
12192 *) proxy_http.c bugfixes: [Chuck Murcko]
12193 1) fixes possible NULL pointer reference w/NoCache
12194 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
12195 host would cache nothing if it was in the local domain,
12196 and the local domain was in the NoCache list)
12197 3) Adds Host: header when not available
12198 4) Some code cleanup and clarification
12200 *) mod_include.c bugfixes:
12201 1) Fixed an ommission that caused include variables to not
12202 be parsed in config errmsg directives [Howard Fear]
12203 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
12204 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
12205 4) Allow backslash-escaping to all quoted text
12206 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
12207 5) Pass variable to command line if not set in XSSI's env
12210 *) Fix infinite loop when processing Content-language lines in
12211 type-map files. [Alexei Kosut]
12213 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
12215 *) Fixed problem in set_[user|group] that prevented CGI execution
12216 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
12218 *) Added PORTING information file. [Jim Jagielski]
12220 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
12222 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
12224 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
12225 USE_FCNTL_SERIALIZED_ACCEPT was intended.
12227 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
12228 which caused problems of systems where socket s_addr is >32bits.
12230 *) Added comment to explain (r->chunked = 1) side-effect in
12231 http_protocol.c [Roy Fielding]
12233 *) Replaced use of index() in mod_expires.c with more appropriate
12234 and portable isdigit() test. [Ben Laurie]
12236 *) Updated Configure for ...
12237 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
12238 *-dg-dgux* (bad pattern match)
12239 QNX (DEF_WANTHSREGEX=yes)
12240 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
12242 *-unixware211 (new)
12243 and added some user diagnostic info. [Ben Laurie]
12245 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
12246 for better portability. [Jim Jagielski]
12248 *) Updated helpers/GuessOS for ...
12249 SCO 5 (recognize minor releases)
12250 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
12251 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
12252 IRIX64 (-sgi-irix64)
12253 ULTRIX (-unknown-ultrix)
12254 SINIX (-whatever-sysv4)
12255 NCR Unix (-ncr-sysv4)
12256 and fixed something in helpers/PrintPath [Ben Laurie]
12258 Changes with Apache 1.2b1
12260 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
12262 Changes with Apache 1.1.1
12264 *) Fixed bug where Cookie module would make two entries in the
12265 logfile for each access [Mark Cox]
12267 *) Fixed bug where Redirect in .htaccess files would cause memory
12268 leak. [Nathan Neulinger]
12270 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
12272 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
12274 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
12276 Changes with Apache 1.1.0
12278 *) Bring NeXT support up to date. [Takaaki Matsumoto]
12280 *) Bring QNX support up to date. [Ben Laurie]
12282 *) Make virtual hosts default to main server keepalive parameters.
12283 [Alexei Kosut, Ben Laurie]
12285 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
12287 *) Fix missing address family for connect, also remove unreachable statement
12288 in mod_proxy. [Ben Laurie]
12290 *) mod_env now turned on by default in Configuration.tmpl.
12292 *) Bugs which were fixed:
12293 a) yet more mod_proxy bugs [Ben Laurie]
12294 b) CGI works again with inetd [Alexei Kosut]
12295 c) Leading colons were stripped from passwords [osm@interguide.com]
12296 d) Another fix to multi-method Limit problem [jk@tools.de]
12298 Changes with Apache 1.1b4
12300 *) r->bytes_sent variable restored. [Robert Thau]
12302 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
12304 *) More possibly unsecure programs removed from the support directory.
12306 *) More mod_auth_msql authentication improvements.
12308 *) VirtualHosts based on Host: headers no longer conflict with the
12311 *) OS/2 compatibility enhancements. [Gary Smiley]
12313 *) POST now allowed to directory index CGI scripts.
12315 *) Actions now work with files of the default type.
12317 *) Bugs which were fixed:
12318 a) more mod_proxy bugs
12319 b) early termination of inetd requests
12320 c) compile warnings on several systems
12321 d) problems when scripts stop reading output early
12323 Changes with Apache 1.1b3
12325 *) Much of cgi-bin and all of cgi-src has been removed, due to
12326 various security holes found and that we could no longer support
12329 *) The "Set-Cookie" header is now special-cased to not merge multiple
12330 instances, since certain popular browsers can not handle multiple
12331 Set-Cookie instructions in a single header. [Paul Sutton]
12333 *) rprintf() added to buffer code, occurrences of sprintf removed.
12336 *) CONNECT method for proxy module, which means tunneling SSL should work.
12337 (No crypto needed) Also a NoCache config directive.
12339 *) Several API additions: pstrndup(), table_unset() and get_token()
12340 functions now available to modules.
12342 *) mod_imap fixups, in particular Location: headers are now complete
12345 *) New "info" module which reports on installed module set through a
12346 special URL, a la mod_status.
12348 *) "ServerPath" directive added - allows for graceful transition
12349 for Host:-header-based virtual hosts.
12351 *) Anonymous authentication module improvements.
12353 *) MSQL authentication module improvements.
12355 *) Status module design improved - output now table-based. [Ben Laurie]
12357 *) htdigest utility included for use with digest authentication
12360 *) mod_negotiation: Accept values with wildcards to be treated with
12361 less priority than those without wildcards at the same quality
12362 value. [Alexei Kosut]
12364 *) Bugs which were fixed:
12365 a) numerous mod_proxy bugs
12366 b) CGI early-termination bug [Ben Laurie]
12367 c) Keepalives not working with virtual hosts
12368 d) RefererIgnore problems
12369 e) closing fd's twice in mod_include (causing core dumps on
12370 Linux and elsewhere).
12372 Changes with Apache 1.1b2
12375 a) core dumps in mod_digest
12376 b) truncated hostnames/ip address in the logs
12377 c) relative URL's in mod_imap map files
12379 Changes with Apache 1.1b1
12381 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12383 Changes with Apache 1.0.3
12385 *) Internal redirects which occur in mod_dir.c now preserve the
12386 query portion of a request (the bit after the question mark).
12389 *) Escape active characters '<', '>' and '&' in html output in
12390 directory listings, error messages and redirection links.
12393 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12395 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12398 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12400 *) Reset timeout timer after each successful fwrite() to the network.
12401 This patch adds a reset_timeout() procedure that is called by
12402 send_fd() to reset the timeout ever time data is written to the net.
12405 *) timeout() signal handler now checks for SIGPIPE and reports
12406 lost connections in a more user friendly way. [Rob Hartill]
12408 *) Location of the "scoreboard" file which used to live in /tmp is
12409 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12410 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12412 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12414 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12415 which caused a SEGV with cookies enabled
12417 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12420 *) Log the UNIX textual error returned by some system calls, in
12421 particular errors from accept() [David Robinson]
12423 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12425 Changes with Apache 1.0.2
12427 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12428 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12430 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12433 *) past changes to http_config.c to only use the
12434 setrlimit function on systems defining RLIMIT_NOFILE
12435 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12436 for SUNOS and prototypes the needed functions.
12438 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12441 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12443 *) Merge multiple headers from CGI scripts instead of taking last
12444 one. [David Robinson]
12446 *) Add support for SCO 5. [Ben Laurie]
12448 Changes with Apache 1.0.1
12450 *) Silence mod_log_referer and mod_log_agent if not configured
12453 *) Recursive includes can occur if the client supplies PATH_INFO data
12454 and the server provider uses relative links; as file.html
12455 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
12457 *) The replacement for initgroups() did not call {set,end}grent(). This
12458 had two implications: if anything else used getgrent(), then
12459 initgroups() would fail, and it was consuming a file descriptor.
12462 *) On heavily loaded servers it was possible for the scoreboard to get
12463 out of sync with reality, as a result of a race condition.
12464 The observed symptoms are far more Apaches running than should
12465 be, and heavy system loads, generally followed by catastrophic
12466 system failure. [Ben Laurie]
12468 *) Fix typo in license. [David Robinson]
12470 Changes with Apache 1.0.0 23 Nov 1995
12472 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
12474 Changes with Apache 0.8.16 05 Nov 1995
12476 *) New man page for 'httpd' added to support directory [David Robinson]
12478 *) .htgroup files can have more than one line giving members for a
12479 given group (each must have the group name in front), for NCSA
12480 back-compatibility [Robert Thau]
12482 *) Mutual exclusion around accept() is on by default for SVR4 systems
12483 generally, since they generally can't handle multiple processes in
12484 accept() on the same socket. This should cure flaky behavior on
12485 a lot of those systems. [David Robinson]
12487 *) AddType, AddEncoding, and AddLanguage directives take multiple
12488 extensions on a single command line [David Robinson]
12490 *) UserDir can be disabled for a given virtual host by saying
12491 "UserDir disabled" in the <VirtualHost> section --- it was a bug
12492 that this didn't work. [David Robinson]
12494 *) Compiles on QNX [Ben Laurie]
12496 *) Corrected parsing of ctime time format [David Robinson]
12498 *) httpd does a perror() before exiting if it can't log its pid
12499 to the PidFile, to make diagnosing the error a bit easier.
12502 *) <!--#include file="..."--> can no longer include files in the
12503 parent directory, for NCSA back-compatibility. [David Robinson]
12505 *) '~' is *not* escaped in URIs generated for directory listings
12508 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
12510 *) Fixed bug involving handling URIs with escaped %-characters
12511 in redirects [David Robinson]
12513 Changes with Apache 0.8.15 14 Oct 1995
12515 *) Switched to new, simpler license
12517 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
12519 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
12521 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
12523 *) Correctly handles internal redirects to files with names containing '%'
12526 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
12528 *) Use geteuid() rather than getuid() to see if we have root privilege,
12529 so that server correctly resets privilege if run setuid root. [Andrew
12532 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
12535 *) Fix relative URLs in imagemap files [Randy Terbush]
12537 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
12540 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
12541 entries all name the same one. [David Robinson]
12543 *) Fix directory listings with filenames containing unusual characters
12546 *) Better URI-escaping for generated URIs in directories with filenames
12547 containing unusual characters [Ben Laurie]
12549 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
12551 *) Unblock alarms on error return from spawn_child() [David Robinson]
12553 *) Sample Config files have extra note for SCO users [Ben Laurie]
12555 *) Configuration has note for HP-UX users [Rob Hartill]
12557 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
12559 *) Nuked bogus #define in httpd.h [David Robinson]
12561 *) Better test for whether a system has setrlimit() [David Robinson]
12563 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
12565 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
12568 Changes with Apache 0.8.14 19 Sep 1995
12570 *) Compiles on SCO ODT 3.0 [Ben Laurie]
12572 *) AddDescription works (better) [Ben Laurie]
12574 *) Leaves an intelligible error diagnostic when it can't set group
12575 privileges on standalone startup [Andrew Wilson]
12577 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
12578 that machine, which claims to be BSD but does not support RLIMIT.
12581 *) gcc -Wall no longer complains about an unused variable when util.c
12582 is compiled with -DMINIMAL_DNS [Andrew Wilson]
12584 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
12586 Changes with Apache 0.8.13 07 Sep 1995
12588 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
12590 *) Have built-in imagemap code recognize & honor Point directive [James
12593 *) Generate cleaner directory listings in directories with a mix of
12594 long and short filenames [Rob Hartill]
12596 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
12598 *) Properly default ServerName for virtual servers [Robert Thau]
12600 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
12601 Paul Richards and a cast of thousands...]
12603 *) On self-identified BSD systems (we don't try to guess any more),
12604 allocate a few extra file descriptors per virtual host with setrlimit,
12605 if we can, to avoid running out. [Randy Terbush]
12607 *) Write 22-character lock file name into buffer with enough space
12608 on startup [Konstantin Olchanski]
12610 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
12613 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
12615 *) Suppress -Wall warning by initializing variable in negotiation code
12616 [Tobias Weingartner]
12618 Changes with Apache 0.8.12 31 Aug 1995
12620 *) Doesn't pause three seconds after including a CGI script which is
12621 too slow to die off (this is done by not even trying to kill off
12622 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
12623 after the entire document has been processed). [Robert Thau]
12625 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
12627 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
12629 *) Allows .htaccess files to override <Directory> sections naming the
12630 same directory [David Robinson]
12632 *) Removed an efficiency hack in sub_req_lookup_uri which was
12633 causing certain extremely marginal cases (e.g., ScriptAlias of a
12634 *particular* index.html file) to fail. [David Robinson]
12636 *) Doesn't log an error when the requested URI requires
12637 authentication, but no auth header line was supplied by the
12638 client; this is a normal condition (the client doesn't no auth is
12639 needed here yet). [Robert Thau]
12641 *) Behaves more sanely when the name server loses its mind [Sean Welch]
12643 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
12645 *) RFC931 code no longer passes out name of prior clients on current
12646 requests if the current request came from a server that doesn't
12647 do RFC931. [David Robinson]
12649 *) Configuration script accepts "Module" lines with trailing whitespace.
12652 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
12654 *) Cleaned up comments in mod_cgi.c [Robert Thau]
12656 Changes with Apache 0.8.11 24 Aug 1995
12658 *) Wildcard <Directory> specifications work. [Robert Thau]
12660 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
12662 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
12663 the file being requested itself, in addition to the directories leading
12664 up to it. [Robert Thau]
12666 *) Logs access failures due to symlink checks or invalid client address
12667 in the error log [Roy Fielding, Robert Thau]
12669 *) Symlink checks deal correctly with systems where lstat of
12670 "/path/to/some/link/" follows the link. [Thau, Fielding]
12672 *) Doesn't reset DirectoryIndex to 'index.html' when
12673 other directory options are set in a .htaccess file. [Robert Thau]
12675 *) Clarified init code and nuked bogus warning in mod_access.c
12676 [Florent Guillaume]
12678 *) Corrected several directives in sample srm.conf
12679 --- includes corrections to directory indexing icon-related directives
12680 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
12681 icons for encodings right, and turning on AddEncoding by default).
12684 *) Corrected descriptions of args to AddIcon and AddAlt in command table
12687 *) INSTALL & README mention "contributed modules" directory [Brian
12690 *) Fixed English in the license language... "for for" --> "for".
12693 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
12694 mod_alias.c, merging it almost completely with handling of Alias, and
12695 adding a 'notes' field to the request_rec which allows the CGI module
12696 to discover whether the Alias module has put this request through
12697 ScriptAlias (which it needs to know for back-compatibility, as the old
12698 NCSA code did not check Options ExecCGI in ScriptAlias directories).
12701 Changes with Apache 0.8.10 18 Aug 1995
12703 *) AllowOverride applies to the named directory, and not just
12704 subdirectories. [David Robinson]
12706 *) Do locking for accept() exclusion (on systems that need it)
12707 using a special file created for the purpose in /usr/tmp, and
12708 not the error log; using the error log causes real problems
12709 if it's NFS-mounted; this is known to be the cause of a whole
12710 lot of "server hang" problems with Solaris. [David Robinson;
12711 thanks to Merten Schumann for help diagnosing the problem].
12713 Changes with Apache 0.8.9 12 Aug 1995
12715 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
12717 *) Nested includes see environment variables of the including document,
12718 for NCSA bug-compatibility (some sites have standard footer includes
12719 which try to print out the last-modified date). [Eric Hagberg/Robert
12722 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
12723 URI as a CGI script, even if it would have been treated as something
12724 else if requested directly, for NCSA back-compatibility. (Note that
12725 this means that people who know the name of the script can see the
12726 code just by asking for it). [Robert Thau]
12728 *) New version of dbmmanage script included in support directory as
12731 *) Check if scoreboard file couldn't be opened, and say so, rather
12732 then going insane [David Robinson]
12734 *) POST to CGI works on A/UX [Jim Jagielski]
12736 *) AddIcon and AddAlt commands work properly [Rob Hartill]
12738 *) NCSA server push works properly --- the Arena bug compatibility
12739 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
12740 if you still want the workaround). [Rob Hartill]
12742 *) If client didn't submit any Accept-encodings, ignore encodings in
12743 content negotiation. (NB this will all have to be reworked anyway
12744 for the new HTTP draft). [Florent Guillaume]
12746 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
12748 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
12750 *) Give Redirect priority over Alias, for NCSA bug compatibility
12753 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
12754 paralleling earlier bug fix for CGI [David Robinson]
12756 *) If DBM auth is improperly configured, report a server error and don't
12759 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
12760 it seems to work well enough without it (even in a 10 hits/sec
12761 workout), and the overhead for the locking under A/UX is
12762 alarmingly high (though it is very low on other systems).
12763 [Eric Hagberg, Jim Jagielski]
12765 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
12767 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
12768 Behlendorf/Eric Hagberg]
12770 *) More improvements to default Configuration for A/UX [Jim Jagielski]
12772 *) Compiles clean on NEXT [Rob Hartill]
12774 *) Compiles clean on SGI [Robert Thau]
12776 Changes with Apache 0.8.8 08 Aug 1995
12778 *) SunOS library prototypes now never included unless explicitly
12779 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
12780 people using GNU libc on SunOS are screwed by prototypes for the
12783 (Those who wish to compile clean with gcc -Wall on a standard
12784 SunOS setup need the prototypes, and may obtain them using
12785 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
12786 with nonstandard libraries are presumably competent to make their
12789 *) Strips trailing '/' characters off both args to the Alias command,
12790 to make 'Alias /foo/ /bar/' work.
12792 Changes with Apache 0.8.7 03 Aug 1995
12794 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
12795 [reported by David Robinson]
12797 *) Compiles clean on OSF/1 [David Robinson]
12799 *) Added some of the more recent significant changes (AddLanguage stuff,
12800 experimental LogFormat support) to CHANGES file in distribution root
12803 Changes with Apache 0.8.6 02 Aug 1995
12805 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
12806 (If you actually wanted a conditional GET which bypassed the cache, you
12807 couldn't get it). [Reported by Roy Fielding]
12809 *) Properly terminate headers on '304 Not Modified' replies to conditional
12810 GETs --- no browser we can find cares much, but the CERN proxy chokes.
12811 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
12813 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
12815 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
12816 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
12817 and older versions don't set the __SUNPRO_C preprocessor variable). On
12818 all other systems, these are never used anyway. [Reported by Mark Cox].
12820 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
12822 Changes with Apache 0.8.5 01 Aug 1995
12824 *) Added last-minute configurable log experiment, as optional module
12826 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
12827 properly. (One-line fix to http_protocol.c).
12829 *) Work around bogus behavior when reloading from Netscape.
12830 It's Netscape's bug --- for some reason they expect a request with
12831 If-modified-since: to not function as a conditional GET if it also
12832 comes with Pragma: no-cache, which is way out of line with the HTTP
12833 spec (according to Roy Fielding, the redactor).
12835 *) Added parameter to set maximum number of server processes.
12837 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
12840 *) IdentityCheck bugfix [Chuck Murcko].
12842 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
12844 *) More sample config file corrections; add extension to AddType for
12845 *.asis, move AddType generic description to its proper place, and
12846 fix miscellaneous typos. [ Alexei Kosut ]
12848 *) Deleted the *other* reference to the regents from the Berkeley
12849 legal disclaimer (everyplace).
12851 *) Nuked Shambhala name from src/README; had already cleaned it out
12852 of everywhere else.
12854 Changes with Apache 0.8.4
12856 *) Changes to server-pool management parms --- renamed current
12857 StartServers to MinSpareServers, created separate StartServers
12858 parameter which means what it says, and renamed MaxServers to
12859 MaxSpareServers (though the old name still works, for NCSA 1.4
12860 back-compatibility). The old names were generally regarded as
12861 too confusing. Also altered "docs" in sample config files.
12863 *) More improvements to default config files ---
12864 sample directives (commented out) for XBitHack, BindAddress,
12865 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
12866 defaults, AddTypes for send-as-is and imagemap magic types, and
12867 improvements to samples for DirectoryIndex [Alexei Kosut]
12869 *) Yet more improvements to default config files --- changes to
12870 Alexei's sample AddLanguage directives, and sample LanguagePriority
12871 [ Florent Guillaume ]
12873 *) Set config file locations properly if not set in httpd.conf
12876 *) Don't escape URIs in internal redirects multiple times; don't
12877 do that when translating PATH_INFO to PATH_TRANSLATED either.
12880 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
12882 Changes with Apache 0.8.3
12884 *) Edited distribution README to *briefly* summarize installation
12885 procedures, and give a pointer to the INSTALL file in the src/
12888 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
12889 recent NCSA distributions.
12891 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
12892 exist for the same directory, use both and don't segfault. [Reported
12895 *) Proper makefile dependencies [David Robinson]
12897 *) Note (re)starts in error log --- reported by Rob Hartill.
12899 *) Only call no2slash() after get_path_info() has been done, to
12900 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
12901 reported by Andrew Wilson, though this one is probably a real bug]
12903 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
12904 dump core when Referer is not supplied. [Randy Terbush]
12906 *) Lightly edited sample config files to refer people to our documentation
12907 instead of NCSA's, and to list Rob McCool as *original* author (also
12908 deleted his old, and no doubt non-functional email address). Would be
12909 nice to have examples of new features...
12911 Changes with Apache 0.8.2 19 Jul 1995
12913 *) Added AddLanuage code [Florent Guillaume]
12915 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
12917 *) All sorts of problems when MultiViews finds a directory. It would
12918 be nice if mod_dir.c was robust enough to handle that, but for now,
12919 just punt. [reported by Brian Behlendorf]
12921 *) Wait for all children on restart, to make sure that the old socket
12922 is gone and we can reopen it. [reported by Randy Terbush]
12924 *) Imagemap module is enabled in default Configuration
12926 *) RefererLog and UserAgentLog modules properly default the logfile
12929 *) Mark Cox's mod_cookies added to the distribution as an optional
12930 module (commented out in the default Configuration, and noted as
12931 an experiment, along with mod_dld). [Mark Cox]
12933 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
12935 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
12937 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
12939 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
12942 Changes with Apache 0.8.1
12944 *) New imagemap module [Randy Terbush]
12946 *) Replacement referer log module with NCSA-compatible RefererIgnore
12947 [Matthew Gray again]
12949 *) Don't mung directory listings with very long filenames.
12950 [Florent Guillaume]
12952 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
12954 *) New config script. See INSTALL for info. [Robert Thau]
12956 *) Scoreboard mechanism for regulating the number of extant server
12957 processes. MaxServers and StartServers defaults are the same as
12958 for NCSA, but the meanings are slightly different. (Actually,
12959 I should probably lower the MaxServers default to 10).
12961 Before asking for a new connection, each server process checks
12962 the number of other servers which are also waiting for a
12963 connection. If there are more than MaxServers, it quietly dies
12964 off. Conversely, every second, the root, or caretaker, process
12965 looks to see how many servers are waiting for a new connection;
12966 if there are fewer than StartServers, it starts a new one. This
12967 does not depend on the number of server processes already extant.
12968 The accounting is arranged through a "scoreboard" file, named
12969 /tmp/htstatus.*, on which each process has an independent file
12970 descriptor (they need to seek without interference).
12972 The end effect is that MaxServers is the maximum number of
12973 servers on an *inactive* server machine, but more will be forked
12974 off to handle unusually heavy loads (or unusually slow clients);
12975 these will die off when they are no longer needed --- without
12976 reverting to the overhead of full forking operation. There is a
12977 hard maximum of 150 server processes compiled in, largely to
12978 avoid forking out of control and dragging the machine down.
12979 (This is arguably too high).
12981 In my server endurance tests, this mechanism did not appear to
12982 impose any significant overhead, even after I forced it to put the
12983 scoreboard file on a normal filesystem (which might have more
12984 overhead than tmpfs). [Robert Thau]
12986 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
12989 *) Read .htaccess files even in directory with <Directory> section.
12990 (Former incompatibility noted on mailing list, now fixed). [Robert
12993 *) "HEAD /" gives the client a "Bad Request" error message, rather
12994 than trying to send no body *and* no headers. [Cliff Skolnick].
12996 *) Don't produce double error reports for some very obscure cases
12997 mainly involving auth configuration (the "all modules decline to
12998 handle" case which is a sure sign of a server bug in most cases,
12999 but also happens when authentication is badly misconfigured).
13002 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
13003 it's *for*, and this sort of thing really shouldn't be cluttering
13004 up the Makefile). [Robert Thau]
13006 *) Incidental code cleanups in http_main.c --- stop dragging
13007 sa_client around; just declare it where used. [Robert Thau]
13009 *) Another acc-related fix. (It doesn't like const char
13010 in some places...). [Mark Cox]
13012 Changes with Shambhala 0.6.1 13 Jul 1995
13014 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
13015 Also, fixed auth typo in http_protocol.c unmasked by this fix.
13017 *) Compiles clean with acc on SunOS [Paul Sutton]
13019 *) Reordered modules in modules.c so that Redirect takes priority
13020 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
13021 believe it or not, he has an actual site with a ScriptAlias and
13022 a Redirect declared for the *exact same directory*. Even *my*
13023 compatibility fetish wouldn't motivate me to fix this if the fix
13024 required any effort, but it doesn't, so what the hey.
13026 *) Fixed to properly default several server_rec fields for virtual
13027 servers from the corresponding fields in the main server_rec.
13028 [Cliff Skolnick --- 'port' was a particular irritant].
13030 *) No longer kills off nph- child processes before they are
13031 finished sending output. [Matthew Gray]
13033 Changes with Shambhala 0.6.0 10 Jul 1995
13035 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
13036 the connection to the client in an "aborted" state, but otherwise
13037 allow whatever handlers are running to clean up. hard_timeout()s
13038 abort the request in progress completely; anything not tied to some
13039 resource pool cleanup will leak. They're still around because I
13040 haven't yet come up with a more elegant way of handling
13041 timeouts when talking to something that isn't the client. The
13042 default_handler and the dir_handler now use soft timeouts, largely
13043 so I can test the feature. [Robert Thau]
13045 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
13046 the case of log handlers dying prematurely is probably handled VERY
13047 gracelessly at this point, and if the logger stops reading input,
13048 the server will hang. (It is known to correctly restart the
13049 logging process on server restart; this is (should be!) going through
13050 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
13051 script). [Robert Thau]
13053 *) asis files supported (new module). [Robert Thau]
13055 *) IdentityCheck code is compiled in, but has not been tested. (I
13056 don't know anyone who runs identd). [Robert Thau]
13058 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
13059 came in with the request, for NCSA bug-compatibility. [Robert Thau]
13061 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
13063 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
13064 as timeouts are not in scope. [Robert Thau]
13066 *) quoted-string args in config files now handled correctly (doesn't drop
13067 the last character). [Robert Thau; reported by Randy Terbush]
13069 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
13070 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
13072 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
13073 default default type); the former default default behavior when all
13074 type-checkers defaulted had been a core dump. [Paul Sutton]
13076 *) Copy filenames out of the struct dirent when indexing
13077 directories. (On Linux, readdir() returns a pointer to the same
13078 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
13080 Changes with Shambhala 0.5.3 [not released]
13082 *) Default response handler notes "file not found" in the error log,
13083 if the file was not found. [Cliff Skolnick].
13085 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
13086 code no longer sets up bogus PATH_INFO which fakes out the directory
13087 handler). [Cliff Skolnick]
13089 Changes with Shambhala 0.5.2 06 Jul 1995
13091 *) Changes to http_main.c --- root server no longer plays silly
13092 games with SIGCHLD, and so now detects and replaces dying
13093 children. Child processes just die on SIGTERM, without taking
13094 the whole process group with them. Potential problem --- if any
13095 child process refuses to die, we hang in restart.
13096 MaxRequestsPerChild may still not work, but it certainly works
13097 better than it did before this! [Robert Thau]
13099 *) mod_dir.c bug fixes: ReadmeName and HeaderName
13100 work (or work better, at least); over-long description lines
13101 properly terminated. [Mark Cox]
13103 *) http_request.c now calls unescape_url() more places where it
13104 should [Paul Sutton].
13106 *) More directory handling bugs (reported by Cox)
13107 Parent Directory link is now set correctly. [Robert Thau]
13109 Changes with Shambhala 0.5.1 04 Jul 1995
13111 *) Generalized cleanup interface in alloc.c --- any function can be
13112 registered with alloc.c as a cleanup for a resource pool;
13113 tracking of files and file descriptors has been reimplemented in
13114 terms of this interface, so I can give it some sort of a test.
13117 *) More changes in alloc.c --- new cleanup_for_exec() function,
13118 which tracks down and closes all file descriptors which have been
13119 registered with the alloc.c machinery before the server exec()s a
13120 child process for CGI or <!--#exec-->. CGI children now get
13121 started with exactly three file descriptors open. Hopefully,
13122 this cures the problem Rob H. was having with overly persistent
13123 CGI connections. [Robert Thau]
13125 *) Mutual exclusion around the accept() in child_main() --- this is
13126 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
13127 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
13128 This uses fcntl(F_SETLK,...) on the error log descriptor because
13129 flock() on that descriptor won't work on systems which have BSD
13130 flock() semantics, including (I think) Linux 1.3 and Solaris.
13132 This does work on SunOS (when the server is idle, only one
13133 process in the pool is waiting on accept()); it *ought* to work
13134 on the other systems. [Robert Thau]
13136 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
13138 *) sizeof(*sa_client) bugfix from [Rob Hartill]
13140 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
13142 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
13143 be unnecessary if I go to the revised timeout-handling scheme).
13146 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
13147 string) even if none came in with the request. [Robert Thau]
13149 *) CHANGES file added to distribution ;-).
13151 Changes with Shambhala 0.4.5
13153 *) mod_dld --- early dynamic loading support [rst]
13154 *) Add wildcard content handlers for XBITHACK; default_hander now
13155 invoked with that mechanism (as a handler hanging off mod_core) [rst]
13156 *) XBITHACK supported as a wildcard content-handler, and
13157 configurable at run-time (not just at compile time, as in the
13158 "patchy server" releases) [rst]
13160 Changes with Shambhala 0.4.4 30 Jun 1995
13162 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
13163 *) Handle Addtype x/y .z [rst, reported by Cox]
13165 Changes with Shambhala 0.4.3
13167 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
13168 synonymous [rst, terbush]
13170 Changes with Shambhala 0.4.1 28 Jun 1995
13172 *) First-cut virtual host implementation; some refit in the config
13173 reading code, and log management, was necessary to support this [rst]
13174 *) Sub-pool machinery, originally added to avoid excessive storage
13175 allocation on listings of large directories (which turned out to
13176 be the problem that the 0.3 storage accounting was added to
13177 find). Subrequests and mod_dir changed to use subpools. [rst]
13178 *) More memory debugging --- free list consistency checks. [rst]
13179 *) Added err_headers to request_rec, with support elsewhere [rst]
13180 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
13182 Changes with Shambhala 0.3 19 Jun 1995
13184 *) Switch ONE_PROCESS to a runtime command-line option (-X)
13185 *) Don't compile in mod_ai_backcompat by default
13186 *) Switch name of server from Apache to Shambhala in Makefile
13187 *) Add some accounting routines to track memory usage in the pools,
13190 Changes with Shambhala 0.2
13192 *) Set DOCUMENT_ROOT CGI variable
13193 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
13194 *) Add critical section protection to handling of cleanup structures
13196 *) Significant code reorg within the server core to group related
13197 functions together [rst]
13198 *) Correctly handle clients that hang up before sending any request
13200 *) Replace dying child processes. [rst]
13202 Changes with Shambhala 0.1 12 Jun 1995
13204 Major rewrite of the pre-existing "patchy server" codebase, by
13205 Robert Thau (rst). Significant portions of the server code, such
13206 as configuration-file handling and HTTP authentication support,
13207 were ripped out and rewritten from scratch. Code that was not
13208 completely rewritten was significantly altered.
13210 Major changes with this release include:
13212 *) Introduction of the module API; in request handling, the central
13213 machinery just dispatches to various modules, which actually do
13214 most of the work. Configuration handling is similar --- modules
13215 declare their own commands, and the central machinery just
13216 dispatches to them.
13218 API features from shambhala/0.1 were substantially unchanged in
13219 Apache 1.0 and 1.1. (1.0 API features not yet present in this
13220 release, such as wildcard handlers and subpools, were added in
13221 subsequent Shambhala releases, and were also generally rst's
13224 *) This release included the following modules:
13226 mod_access (access control --- allow and deny directives),
13227 mod_alias (Alias and Redirect commands),
13228 mod_auth (straight HTTP authentication, based on flat-files)
13229 mod_auth_dbm (same, with dbm files)
13230 mod_cgi (CGI scripts and, in this release, ScriptAlias)
13231 mod_common_log (CLF access logs; later renamed mod_log_common)
13232 mod_dir (directory indexing)
13233 mod_include (server-side includes)
13234 mod_mime (AddType directives)
13235 mod_negotiation (content negotiation)
13236 mod_userdir (support for users' public_html directories)
13238 It also included a mod_ai_backcompat, which was a private hack
13239 for back-compatibility with rst's own AI-lab servers.
13241 All of these modules were substantially complete, and functional
13242 or nearly so (a few, which implemented features not in use at
13243 Thau's site, required patches of a few lines).
13245 *) sub-request machinery, to allow modules to determine how other
13246 modules would assign MIME types to a given file, or optionally
13247 serve its content (this is heavily used by mod_dir, mod_include
13248 and mod_negotiation).
13250 *) Resource pool system for keeping track of memory allocated and
13251 files opened in service of a particular request. Much of the
13252 code in the modules (when they weren't rewrites) was adjusted to
13253 replace a pervasive convention of using fixed-size buffers on
13254 the stack with an equally pervasive convention of using memory
13255 allocated with palloc().
13257 *) Reorganization of data structures associated with a given
13258 request to eliminate use of global variables and the troublesome
13259 unmunge_name function (used in NCSA and early Apache releases to
13260 attempt to determine the URI which mapped to a given filename
13261 --- a difficult proposition, given that it is easy to produce
13262 setups in which multiple URIs map to the same file).
13264 *) Source files renamed and rearranged
13266 *) Very simple pre-forking behavior --- parent process forked off a
13267 fixed number of children, and then just waited for SIGHUP.
13269 *) Other more minor changes too numerous to list.
13271 This release included modified versions of a lot of code from the
13272 Apache 0.6.4 public release, plus an early pre-forking patch
13273 codeveloped by Robert Thau and Rob Hartill.
13275 Changes with Apache 0.7.3 20 Jun 1995
13277 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
13278 were incorporated by Rob Hartill on the main branch while Robert Thau
13279 worked on the Shambhala rewrite above. Most were merged into the
13280 Shambala architecture after Apache 0.8.0.
13282 Changes with Apache 0.6.4 13 May 1995
13284 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
13287 Changes with Apache 0.5.1 10 Apr 1995
13289 Changes with Apache 0.4 02 Apr 1995
13291 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
13294 Changes with Apache 0.3 24 Mar 1995
13296 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
13299 Changes with Apache 0.2 18 Mar 1995
13301 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
13302 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
13303 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
