1 Changes with Apache 2.1.0-dev
3 [Remove entries to the current 2.0 section below, when backported]
5 *) Fix mod_include's expression parser to recognize strings correctly
6 even if they start with an escaped token. [André Malo]
8 *) Major overhaul of mod_include's filter parser. The new parser code
9 is expected to be more robust and should catch all of the edge cases
10 that were not handled by the previous one. This includes a binary
11 incompatible change of mod_include's external API. [André Malo]
13 *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
14 PR 14223. [André Malo]
16 *) mod_log_config: Fix %b log format to write really "-" when 0 bytes
17 were sent (e.g. with 304 or 204 response codes). [Astrid Keßler]
19 *) Fix a bug, where mod_deflate sometimes unconditionally compressed the
20 content if the Accept-Encoding header contained only other tokens than
21 "gzip" (such as "deflate"). PR 21523. [Joe Orton, André Malo]
23 *) mod_rewrite: Catch an edge case, where strange subsequent RewriteRules
24 could lead to a 400 (Bad Request) response. [André Malo]
26 *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously
27 the current rewrite state was just used as lookup path, which lead to
28 strange and often useless results. Related to PR 8493. [André Malo]
30 *) Change Listen directive to bind to all addresses when a hostname is
31 not specified. [Justin Erenkrantz]
33 *) Correct failure with Listen directives on machines with IPv6 enabled.
34 [Colm MacCárthaigh <colm@stdlib.net>, Justin Erenkrantz]
36 *) Fix a link failure in mod_ssl when the OpenSSL libraries contain
37 the ENGINE functions but the engine header files are missing.
40 *) Fix mod_deflate so that it does not call deflate() without checking
41 first whether it has something to deflate. (Currently this causes
42 deflate to generate a fatal error according to the zlib spec.)
43 PR 22259. [Stas Bekman]
45 *) Avoid an infinite recursion, which occured if the name of an included
46 config file or directory contained a wildcard character. PR 22194.
49 *) mod_dav: Use bucket brigades when reading PUT data. This avoids
50 problems if the data stream is modified by an input filter. PR 22104.
51 [Tim Robbins <tim@robbins.dropbear.id.au>, André Malo]
53 *) mod_rewrite: RewriteRules in server context using the force
54 type feature [T=...] no longer disable MultiViews. [André Malo]
56 *) ab: Work over non-loopback on Unix again. PR 21495. [Jeff Trawick]
58 *) mod_rewrite: In external rewrite maps lookup keys containing
59 a newline now cause a lookup failure. PR 14453.
60 [Cedric Gavage <cedric.gavage@unixtech.be>, André Malo]
62 *) mod_rewrite: Allow piped rewrite logs to be relative to ServerRoot.
65 *) mod_ssl: Fix segfaults after renegotiation failure. PR 21370
66 [Hartmut Keil <Hartmut.Keil@adnovum.ch>]
68 *) mod_autoindex: If a directory contains a file listed in the
69 DirectoryIndex directive, the folder icon is no longer replaced
70 by the icon of that file. PR 9587.
71 [David Shane Holden <dpejesh@yahoo.com>]
73 *) mod_authz_groupfile: Strip trailing spaces of group names. This
74 hopefully saves some hours of searching for typos. PR 12863.
77 *) Remove an extra bit of unnecessary code from the recently
78 committed fix for PR 13946 (in mod_rewrite). Reported by
79 Andre Malo. [Paul J. Reder]
81 *) mod_ssl: Fix a problem setting variables that represent the
82 client certificate chain. PR 21397 [Jeff Trawick]
84 *) mod_rewrite: fix a problem in the proxy support of mod_rewrite.
85 The broken code was inserting multiple "proxy:" fields in the
86 rewritten URIs. [PR: 13946]
87 [Submitted by: Eider Oliveira <eider@bol.com.br>]
88 [Updated and reviewed by: Paul J. Reder]
90 *) mod_actions: Propagate the handler name to the action script via
91 the REDIRECT_HANDLER environment variable. [André Malo]
93 *) mod_actions: Introduce the "virtual" modifier to the Action directive,
94 which allows the use of handlers for virtual locations. PR 8431.
97 *) mod_speling: Recognize AcceptPathInfo setting for the particular
98 location. Default is to reject path information. PR 21059.
101 *) mod_ext_filter: Add the ability to filter request bodies.
102 [Philipp Reisner <philipp.reisner@linbit.com>]
104 *) Correct the code in ap_check_cache_feshness to check max_age,
105 smax_age, and expires correctly. Patch submitted by Thomas
106 Castelle [Paul J. Reder]
108 *) mod_cgid: Restart the cgid daemon if it crashes. PR 19849
109 [Glenn Nielsen <glenn@apache.org>]
111 *) Unix: Handle permissions settings for flock-based mutexes in
112 unixd_set_global|proc_mutex_perms(). Allow the functions to be
113 called for any type of mutex. PR 20312 [Jeff Trawick]
115 *) Fix some broken log messages in WinNT MPM.
116 [Juan Rivera <Juan.Rivera@citrix.com>]
118 *) Add support for IMT minor-type wildcards (e.g., text/*) to
119 ExpiresByType. PR#7991 [Ken Coar]
121 *) Ensure that ssl-std.conf is generated at configure time, and switch
122 to using the expanded config variables to work the same as
123 httpd-std.conf PR 19611
126 *) Fix a problem with namespace mappings being dropped in mod_dav_fs;
127 if any property values were set which defined namespaces these
128 came out mangled in the PROPFIND response. PR 11637.
129 [Amit Athavale <amit_athavale@persistent.co.in>]
131 *) prefork MPM: Use the right permissions for the directory created
132 for gprof support. [Jim Carlson <jcarlson@jnous.com>]
134 *) Fix the inability to log errors like exec failure in
135 mod_ext_filter/mod_cgi script children. This was broken after
136 such children stopped inheriting the error log handle.
139 *) Fix a compile failure with recent OpenSSL and picky compilers
140 (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
142 *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
143 the INCLUDE path to be defined properly.
144 PR 11310. [Geoff Thrope <geoff@geoffthorpe.net>]
146 *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
148 *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
149 autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc).
150 [Geoff Thorpe <geoff@geoffthorpe.net>]
152 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
153 [Ian Holsman, André Malo]
155 *) mod_negotiation: quality values are now parsed independent from
156 the current locale. level values are now really parsed as integers.
157 PR 17564. [André Malo]
159 *) Added the WindowsSocketsWorkaround directive for Windows NT/2000/XP
160 to work around problems with certain VPN and Firewall products that
161 have buggy AcceptEx implementations.
162 [Allan Edwards w/ suggestions from Bill Stoddard & Bill Rowe]
164 *) Extend mod_negotiation to evaluate the environment variables
165 no-gzip and gzip-only-text/html the same way as mod_deflate does.
168 *) mod_rewrite: Fix some problems reporting errors with mapping
169 programs (RewriteMap prg:/something). [Jeff Trawick]
171 *) Return 413 if chunk-ext-header is too long rather than reading from
172 the truncated line. PR 15857. [Justin Erenkrantz]
174 *) Allow restart of httpd to occur even with syntax errors in the config
175 file. PR 16813. [Justin Erenkrantz]
177 *) Use APR_LAYOUT instead of APACHE_LAYOUT in configure. PR 15679.
180 *) Remove files on 'make distclean' that should be. PR 15592.
183 *) Allow apachectl to perform status with links and elinks as well.
186 *) Extend the SetEnvIf directive to capture subexpressions of the
187 matched value. [André Malo]
189 *) mod_log_config change optional hook to return previous handler
192 *) Forward port of mod_actions' ability to handle arbitrary methods
193 with the Script directive. [André Malo]
195 *) Let suexec send a message to stderr, if it failed or its policy
196 was violated. This message appears in the error log and allows
197 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
199 *) Modify buildconf to copy all required files into httpd's tree.
200 [Thom May <thom@planetarytramp.net>]
202 *) Allow mod_dav to do weak entity comparison functions.
205 *) Move RFC 1413 ident requests from core to new module mod_ident.
208 *) Add mod_authz_owner - a forward port of "Require file-owner"
209 and "Require file-group", which was already present in version
212 *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
215 *) Replace some of the mutex locking in the worker MPM with
216 atomic operations for higher concurrency. [Brian Pane]
218 *) Allow 'make depend' to work with non-GCC compilers.
221 *) If an httpd.conf has commented out AddModule directives,
222 apxs -i -a will add an un-commented AddModule directive for
223 the new module, which breaks the config.
224 PR: 11212 [Joe Orton]
226 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
228 *) Move the check of the Expect request header field after the hook
229 for ap_post_read_request, since that is the only opportunity for
230 modules to handle Expect extensions. [Justin Erenkrantz]
232 *) Rewrite of aaa modules to an authn/authz model.
233 [Dirk-Willem van Gulik, Justin Erenkrantz]
236 [Apache 2.1.0-dev includes those bug fixes and changes with the
237 Apache 2.0.xx tree as documented, and except as noted, below.]
239 Changes with Apache 2.0.48
241 *) Install config.nice into the build/ directory to make
242 minor version upgrades easier. [Joshua Slive]
244 *) mod_rewrite: Ignore RewriteRules in .htaccess files if the directory
245 containing the .htaccess file is requested without a trailing slash.
246 PR 20195. [André Malo]
248 *) ab: Overlong credentials given via command line no longer clobber
249 the buffer. [André Malo]
251 *) mod_deflate: Don't attempt to hold all of the response until we're
252 done. [Justin Erenkrantz]
254 *) Assure that we block properly when reading input bodies with SSL.
255 PR 19242. [David Deaves <David.Deaves@dd.id.au>, William Rowe]
257 *) Update mime.types to include latest IANA and W3C types. [Roy Fielding]
259 *) mod_ext_filter: Set additional environment variables for use by
260 the external filter. PR 20944. [Andrew Ho, Jeff Trawick]
262 *) Fix buildconf errors when libtool version changes. [Jeff Trawick]
264 *) Remember an authenticated user during internal redirects if the
265 redirection target is not access protected and pass it
266 to scripts using the REDIRECT_REMOTE_USER environment variable.
267 PR 10678, 11602. [André Malo]
269 *) mod_include: Fix a trio of bugs that would cause various unusual
270 sequences of parsed bytes to omit portions of the output stream.
271 PR 21095. [Ron Park <ronald.park@cnet.com>, André Malo, Cliff Woolley]
273 *) Update the header token parsing code to allow LWS between the
274 token word and the ':' seperator. [PR 16520]
275 [Kris Verbeeck <kris.verbeeck@advalvas.be>,Nicel KM <mnicel@yahoo.com>]
277 *) Eliminate creation of a temporary table in ap_get_mime_headers_core()
278 [Joe Schaefer <joe+gmane@sunstarsys.com>]
280 *) Added FreeBSD directory layout. PR 21100.
281 [Sander Holthaus <info@orangexl.com>, André Malo]
283 *) Fix NULL-pointer issue in ab when parsing an incomplete or non-HTTP
284 response. PR 21085. [Glenn Nielsen <glenn@apache.org>, André Malo]
286 *) mod_rewrite: Perform child initialization on the rewrite log lock.
287 This fixes a log corruption issue when flock-based serialization
288 is used (e.g., FreeBSD). [Jeff Trawick]
290 *) Don't respect the Server header field as set by modules and CGIs.
291 As with 1.3, for proxy requests any such field is from the origin
292 server; otherwise it will have our server info as controlled by
293 the ServerTokens directive. [Jeff Trawick]
295 Changes with Apache 2.0.47
297 *) SECURITY [CAN-2003-0192]: Fixed a bug whereby certain sequences
298 of per-directory renegotiations and the SSLCipherSuite directive
299 being used to upgrade from a weak ciphersuite to a strong one
300 could result in the weak ciphersuite being used in place of the
301 strong one. [Ben Laurie]
303 *) SECURITY [CAN-2003-0253]: Fixed a bug in prefork MPM causing
304 temporary denial of service when accept() on a rarely accessed port
305 returns certain errors. Reported by Saheed Akhtar
306 <S.Akhtar@talis.com>. [Jeff Trawick]
308 *) SECURITY [CAN-2003-0254]: Fixed a bug in ftp proxy causing denial
309 of service when target host is IPv6 but proxy server can't create
310 IPv6 socket. Fixed by the reporter. [Yoshioka Tsuneo
311 <tsuneo.yoshioka@f-secure.com>]
313 *) SECURITY [VU#379828] Prevent the server from crashing when entering
314 infinite loops. The new LimitInternalRecursion directive configures
315 limits of subsequent internal redirects and nested subrequests, after
316 which the request will be aborted. PR 19753 (and probably others).
317 [William Rowe, Jeff Trawick, André Malo]
319 *) core_output_filter: don't split the brigade after a FLUSH bucket if
320 it's the last bucket. This prevents creating unneccessary empty
321 brigades which may not be destroyed until the end of a keepalive
323 [Juan Rivera <Juan.Rivera@citrix.com>]
325 *) Add support for "streamy" PROPFIND responses.
326 [Ben Collins-Sussman <sussman@collab.net>]
328 *) mod_cgid: Eliminate a double-close of a socket. This resolves
329 various operational problems in a threaded MPM, since on the
330 second attempt to close the socket, the same descriptor was
331 often already in use by another thread for another purpose.
334 *) mod_negotiation: Introduce "prefer-language" environment variable,
335 which allows to influence the negotiation process on request basis
336 to prefer a certain language. [André Malo]
338 *) Make mod_expires' ExpiresByType work properly, including for
339 dynamically-generated documents. [Ken Coar, Bill Stoddard]
341 Changes with Apache 2.0.46
343 *) SECURITY [CAN-2003-0245]: Fixed a bug causing apr_pvsprintf() to crash
344 by sending an overly long string. This can be triggered remotely
345 through mod_dav, mod_ssl, and other mechanisms. Reported by David
346 Endler <DEndler@iDefense.com>.
347 [Joe Orton <jorton@redhat.com>]
349 *) SECURITY [CAN-2003-0189]: Fixed a denial-of-service vulnerability
350 affecting basic authentication on Unix platforms related to
351 thread-safety in apr_password_validate(). The problem was reported
352 by John Hughes <john.hughes@entegrity.com>.
354 *) Fix for mod_dav. Call the 'can_be_activity' callback, if provided,
355 when a MKACTIVITY request comes in.
356 [Ben Collins-Sussman <sussman@collab.net>]
358 *) Perform run-time query in apxs for apr and apr-util's includes.
361 *) run libtool from the apr install directory (in case that is different
362 from the apache install directory) [Jeff Trawick]
364 *) configure.in: Play nice with libtool-1.5. [Wilfredo Sanchez]
366 *) If mod_mime_magic does not know the content-type, do not attempt to
367 guess. PR 16908. [Andrew Gapon <agapon@telcordia.com>]
369 *) ssl session caching(shmht) : Fix a SEGV problem with SHMHT session
371 [Andreas Leimbacher <andreasl67@yahoo.de>, Madhusudan Mathihalli]
373 *) Add a delete flag to htpasswd.
376 *) Fix mod_rewrite's handling of absolute URIs. The escaping routines
377 now work scheme dependent and the query string will only be
378 appended if supported by the particular scheme. [André Malo]
380 *) Add another check for already compressed content in mod_deflate.
381 PR 19913. [Tsuyoshi SASAMOTO <nazonazo@super.win.ne.jp>]
383 *) Fixes for VPATH builds; copying special.mk and any future .mk files
384 from the source tree as well as the build tree (now creates a usable
385 configuration for apxs), and eliminated redundant -I'nclude paths.
388 *) Code fixes, constness corrections and ssl_toolkit_compat.h updates
389 for SSLC and OpenSSL toolkit compatibility. Still work remains to
390 be done to cripple features based on the limitations of RSA's binary
391 distribution of their SSL-C toolkit.
392 [William Rowe, Madhusudan Mathihalli, Jeff Trawick]
394 *) Linux 2.4+: If Apache is started as root and you code
395 CoreDumpDirectory, coredumps are enabled via the prctl() syscall.
398 *) ap_get_mime_headers_core: allocate space for the trailing null
399 when folding is in effect.
400 PR 18170 [Peter Mayne <PeterMayne@SPAM_SUX.ap.spherion.com>]
402 *) Fix --enable-mods-shared=most and other variants. [Aaron Bannert]
404 *) mod_log_config: Add the ability to log the id of the thread
405 processing the request via new %P formats. [Jeff Trawick]
407 *) Use appropriate language codes for Czech (cs) and Traditional Chinese
408 (zh-tw) in default config files. PR 9427. [André Malo]
410 *) mod_auth_ldap: Use generic whitespace character class when parsing
411 "require" directives, instead of literal spaces only. PR 17135.
414 *) Hook mod_rewrite's type checker before mod_mime's one. That way the
415 RewriteRule [T=...] Flag should work as expected now. PR 19626.
418 *) htpasswd: Check the processed file on validity. If a line is not empty
419 and not a comment, it must contain at least one colon. Otherwise exit
420 with error code 7. [Kris Verbeeck <Kris.Verbeeck@ubizen.com>, Thom May]
422 *) Fix a problem that caused httpd to be linked with incorrect flags
423 on some platforms when mod_so was enabled by default, breaking
424 DSOs on AIX. PR 19012 [Jeff Trawick]
426 *) By default, use the same CC and CPP with which APR was built.
427 The user can override with CC and CPP environment variables.
430 *) Fix ap_construct_url() so that it surrounds IPv6 literal address
431 strings with []. This fixes certain types of redirection.
432 PR 19207. [Jeff Trawick]
434 *) forward port of buffer overflow fixes for htdigest. [Thom May]
436 *) Added AllowEncodedSlashes directive to permit control of whether
437 the server will accept encoded slashes ('%2f') in the URI path.
438 Default condition is off (the historical behaviour). This permits
439 environments in which the path-info needs to contain encoded
440 slashes. PR 543, 2389, 3581, 3589, 5687, 7066, 7865, 14639. [Ken Coar]
442 *) When using Redirect in directory context, append requested query
443 string if there's no one supplied by configuration. PR 10961.
446 *) Unescape the supplied wildcard pattern in mod_autoindex. Otherwise
447 the pattern will not always match as desired. PR 12596.
450 *) mod_autoindex now emits and accepts modern query string parameter
451 delimiters (;). Thus column headers no longer contain unescaped
452 ampersands. PR 10880 [André Malo]
454 *) Enable ap_sock_disable_nagle for Windows. This along with the
455 addition of APR_TCP_NODELAY_INHERITED to apr.hw will cause Nagle
456 to be disabled for Windows. [Allan Edwards]
458 *) Correct a mis-correlation between mpm_common.c and mpm_common.h;
459 This patch reverts us to pre-2.0.46 behavior, using the
460 ap_sock_disable_nagle noop macro, because ap_sock_disable_nagle
461 was never compiled on Win32. [Allan Edwards, William Rowe]
463 *) Fix a build problem with passing unsupported --enable-layout
464 args to apr and apr-util. This broke binbuild.sh as well as
465 user-specified layout parameters. PR 18649 [Justin Erenkrantz,
468 *) If a Date response header was already set in the headers array,
469 this value was ignored in favour of the current time. This meant
470 that Date headers on proxied requests where rewritten when they
471 should not have been. PR: 14376 [Graham Leggett]
473 *) Add code to buildconf that produces an httpd.spec file from
474 httpd.spec.in, using build/get-version.sh from APR.
477 *) Fixed a segfault when multiple ProxyBlock directives were used.
478 PR: 19023 [Sami Tikka <sami.tikka@f-secure.com>]
480 *) SECURITY [CAN-2003-0134] OS2: Fix a Denial of Service vulnerability
481 identified and reported by Robert Howard <rihoward@rawbw.com> that
482 where device names faulted the running OS2 worker process.
483 The fix is actually in APR 0.9.4. [Brian Havard]
485 *) Forward port: Escape special characters (especially control
486 characters) in mod_log_config to make a clear distinction between
487 client-supplied strings (with special characters) and server-side
488 strings. This was already introduced in version 1.3.25.
491 *) mod_deflate: Check also err_headers_out for an already set
492 Content-Encoding: gzip header. This prevents gzip compressed content
493 from a CGI script from being compressed once more. PR 17797.
496 Changes with Apache 2.0.45
498 *) Fix possible segfaults under obscure error conditions within the
499 cgid daemon. [Jeff Trawick, William Rowe]
501 *) SECURITY [CAN-2003-0132]: Close a Denial of Service vulnerability
502 identified by David Endler <DEndler@iDefense.com> on all platforms.
503 An unlimited stream of newlines were acceptable between requests
504 where each <lf> would allocate an 80 byte buffer, leading very
505 quickly to memory exahustion. [Brian Pane]
507 *) Added an rpm build script.
508 [Graham Leggett, Joe Orton <jorton@redhat.com>]
510 *) Simpler, faster code path for request header scanning [Brian Pane]
512 *) SECURITY: Eliminated leaks of several file descriptors to child
513 processes, such as CGI scripts. This fix depends on the APR library
514 release 0.9.2 or later (0.9.3 was distributed with the httpd
515 source tarball for Apache 2.0.45.) PR 17206
516 [Christian Kratzer <ck@cksoft.de>, Bjoern A. Zeeb <bz@zabbadoz.net>]
518 *) Fix path handling of mod_rewrite, especially on non-unix systems.
519 There was some confusion between local paths and URL paths.
520 PR 12902. [André Malo]
522 *) Prevent endless loops of internal redirects in mod_rewrite by
523 aborting after exceeding a limit of internal redirects. The
524 limit defaults to 10 and can be changed using the RewriteOptions
525 directive. PR 17462. [André Malo]
527 *) Win32: Avoid busy wait (consuming all the CPU idle cycles) when
528 all worker threads are busy.
529 [Igor Nazarenko <igor_nazarenko@hotmail.com>]
531 *) Keep the subrequest filter in place when a subrequest is
532 redirected. PR 15423. [Jeff Trawick]
534 *) you can now specify the compression level for mod_deflate.
535 [Ian Holsman, Stephen Pierzchala <stephen@pierzchala.com>,
536 Michael Schroepl <Michael.Schroepl@telekurs.de>]
538 *) mod_deflate: Extend the DeflateFilterNote directive to
539 allow accurate logging of the filter's in- and outstream.
542 *) Allow SSLMutex to select/use the full range of APR locking
543 mechanisms available to it. Also, fix the bug that SSLMutex uses
544 APR_LOCK_DEFAULT no matter what. PR 8122 [Jim Jagielski,
545 martin.t.kutschker@blackbox.net (Martin Kutschker)]
547 *) Restore the ability of htdigest.exe to create files that contain
548 more than one user. PR 12910. [André Malo]
550 *) Improve binary compatibility of the core between debug (aka
551 maintainer-mode) and a non-debug compile.
554 *) mod_usertrack: don't set the cookie in subrequests. This works
555 around the problem that cookies were set twice during fast internal
556 redirects. PR 13211. [André Malo]
558 *) mod_autoindex no longer forgets output format and enabled version
559 sort in linked column headers. [André Malo]
561 *) Use .sv instead of .se as extension for Swedish documents in the
562 default configuration. PR 12877. [André Malo]
564 *) Updated mod_ldap and mod_auth_ldap to support the Novell LDAP SDK SSL
565 and standardized the LDAP SSL support across the various LDAP SDKs.
566 Isolated the SSL functionality to mod_ldap rather than speading it
567 across mod_auth_ldap and mod_ldap. Also added LDAPTrustedCA
568 and LDAPTrustedCAType directives to mod_ldap to allow for a more
569 common method of specifying the SSL certificate.
570 [Dave Ward, Brad Nicholes]
572 *) Fixed mod_ssl's SSLCertificateChain initialization to no longer
573 skip the first cert of the chain by default. This misbehavior
574 was introduced in 2.0.34. PR 14560 [Madhusudan Mathihalli]
576 *) mod_cgi, mod_cgid, mod_ext_filter: Log errors when scripts cannot

602 *) Fixed a problem with mod_ldap which caused it to fault when caching
603 was disabled. Needed to make sure that the code did not
604 attempt to use the cache if it didn't exist. Also fixed some memory
605 leaks which were due to not releasing LDAP resources on error

730 implementation of MCacheMaxStreamingBuffer from mod_cache to
731 mod_mem_cache. MCacheMaxStreamingBuffer now defaults to the
732 lesser of 100,000 bytes or MCacheMaxCacheObjectSize. This should
733 eliminate the need for explicitly coding MCacheMaxStreamingBuffer
734 in most configurations. [Bill Stoddard]

805 *) This fixes a problem where the underlying cache code
806 indicated that there was one more element on the cache
807 than there actually was. This happened since element 0
808 exists but is not used. This code allocates the correct

1139 than copying the file into the heap. [Brian Pane]
1141 *) Modified version check on openssl so that it finds the executable
1142 first and then performs a check of the version, only warning the
1143 user if they chose, or we selected, an old version of OpenSSL.
1144 This change also allows the code to work for non-openssl libraries
1145 selected via the --with-ssl=dir option, which can override the
1146 automated library check in any case. [Roy Fielding]
1148 Changes with Apache 2.0.40
1150 *) SECURITY [CAN-2002-0661] (cve.mitre.org):
1151 Close a very significant security hole that
1152 applies only to the Win32, OS2 and Netware platforms. Unix was not
1153 affected, Cygwin may be affected. Certain URIs will bypass security
1154 and allow users to invoke or access any file depending on the system
1155 configuration. Without upgrading, a single .conf change will close
1156 the vulnerability. Add the following directive in the global server
1157 httpd.conf context before any other Alias or Redirect directives;
1158 RedirectMatch 400 "\\\.\."
1159 Reported by Auriemma Luigi <bugtest@sitoverde.com>.
1162 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1163 Close a path-revealing exposure in multiview type
1164 map negotiation (such as the default error documents) where the
1165 module would report the full path of the typemapped .var file when
1166 multiple documents or no documents could be served based on the mime
1167 negotiation. Reported by Auriemma Luigi <bugtest@sitoverde.com>.
1170 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1171 Close a path-revealing exposure in cgi/cgid when we
1172 fail to invoke a script. The modules would report "couldn't create
1173 child process /path-to-script/script.pl" revealing the full path
1174 of the script. Reported by Jim Race <jrace@qualys.com>.
1177 *) Set aside the apr-iconv and apr_xlate() features for the Win32
1178 build of 2.0.40 so development can be completed. A patch, from
1179 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
1180 will be available for those that wish to work with apr-iconv.
1183 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
1184 chain. [Peter Van Biesen <peter.vanbiesen@vlafo.be>]
1186 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
1187 set to 1, so we can exclude things from the general case with
1188 browsermatch. [Ian Holsman, Andre Schild <A.Schild@aarboard.ch>]
1190 *) Accept multiple leading /'s for requests within the DocumentRoot.
1191 PR 10946 [William Rowe, David Shane Holden <dpejesh@yahoo.com>]
1193 *) Solved the reports of .pdf byterange failures on Win32 alone.
1194 APR's sendfile for the win32 platform collapses header and trailer
1195 buffers into a single buffer. However, we destroyed the pointers
1196 to the header buffer if a trailer buffer was present. PR 10781
1199 *) mod_ext_filter: Add the ability to enable or disable a filter via
1200 an environment variable. Add the ability to register a filter of
1201 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
1203 *) Restore the ability to specify host names on Listen directives.
1204 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh@yahoo.com>]
1206 *) When deciding on the default address family for listening sockets,
1207 make sure we can actually bind to an AF_INET6 socket before
1208 deciding that we should default to AF_INET6. This fixes a startup
1209 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
1211 *) Replace usage of atol() to parse strings when we might want a
1212 larger-than-long value with apr_atoll(), which returns long long.
1213 This allows HTTPD to deal with larger files correctly.
1214 [Shantonu Sen <ssen@apple.com>]
1216 *) mod_ext_filter: Ignore any content-type parameters when checking if
1217 the response should be filtered. Previously, "intype=text/html"
1218 wouldn't match something like "text/html;charset=8859_1".
1221 *) mod_ext_filter: Set up environment variables for external programs.
1222 [Craig Sebenik <craig@netapp.com>]
1224 *) Modified the HTTP_IN filter to immediately append the EOS (end of
1225 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
1226 the caller to determine that no content remains without prefetching
1227 additional POST body. [William Rowe]
1229 *) Get proxy ftp to work over IPv6. [Shoichi Sakane <sakane@kame.net>]
1231 *) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml@suse.de>]
1233 *) Update SuSE layout. [Peter Poeml <poeml@suse.de>]
1235 *) Changes to the internationalized error documents:
1236 Comment them out in the default config file to make the default
1237 install as simple as possible; Correct the english 500 error to
1238 be more understandable; Add a Swedish translation.
1239 [Thomas Sjogren <thomas@northernsecurity.net>,
1240 Erik Abele <erik@codefaktor.de>, Rich Bowen, Joshua Slive]
1242 *) Increase the limit on file descriptors per process in apachectl.
1245 *) Fix a dependency error when building ApacheMonitor, so that Win32
1246 and MSVC now trust that the project is current (when it is).
1247 [James Cox <imajes@php.net>]
1249 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
1250 [Arthur P. Smith <apsmith@aps.org>, Jeff Trawick]
1252 *) APR-Util Renames pending have been completed [Thom May]
1254 *) Performance improvements for the code that reads request
1255 headers (ap_rgetline_core() and related functions) [Brian Pane]
1257 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
1258 to configure the maximum amount of memory the allocators will
1259 hold on to for reuse. Anything over the MaxMemFree threshold
1260 will be free()d. This directive is useful when uncommon large
1261 peaks occur in memory usage. It should _not_ be used to mask
1262 defective modules' memory use. [Sander Striker]
1264 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
1265 scripts would not result in a truncated response.
1266 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
1268 *) Add a filter_init parameter to the filter registration functions
1269 so that a filter can execute arbitrary code before the handlers
1270 are invoked. This resolves a problem where mod_include requests
1271 would incorrectly return a 304. [Justin Erenkrantz]
1273 *) Fix a long-standing bug in 2.0, CGI scripts were being called
1274 with relative paths instead of absolute paths. Apache 1.3 used
1275 absolute paths for everything except for SuExec, this brings back
1276 that standard. [Ryan Bloom]
1278 *) Fix infinite loop due to two HTTP_IN filters being present for
1279 internally redirected requests. PR 10146. [Justin Erenkrantz]
1281 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
1284 *) Fix mod_ext_filter to look in the main server for filter definitions
1285 when running in a vhost if the filter definition is not found in
1286 the vhost. PR 10147 [Jeff Trawick]
1288 *) Support WinNT CGI invocation through ScriptInterpreterSource
1289 'registry' for script interpreter paths and names with non-ascii
1290 characters in the executable filepath. [William Rowe]
1292 *) Support the -w flag on to keep the Win32 console open on error.
1295 *) Normalize the hostname value in the request_rec to all-lowercase
1296 [Perry Harrington <pedward@webcom.com>]
1298 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
1299 extended characters (non US-ASCII) in non-utf8 format. This brings
1300 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
1301 to the cgi application itself. [William Rowe]
1303 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
1304 modules to bring them up to the current apr/apr-util APIs.
1307 *) Fix segfault in mod_mem_cache most frequently observed when
1308 serving the same file to multiple clients on an MP machine.
1311 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
1312 [Brian Degenhardt <bmd@mp3.com>, Ian Holsman]
1314 *) Fix perchild to work with apachectl by adding -k support to perchild.
1315 PR 10074 [Jeff Trawick]
1317 *) Fix a silly htpasswd.c logic error that incorrectly reported that
1318 both -c and -n had been used. PR 9989 [Cliff Woolley]
1320 *) Fixed a mod_include error case in which no HTTP response was sent
1321 to the client if an shtml document contained an unterminated SSI
1322 directive [Brian Pane]
1324 *) Improve ap_get_client_block implementation by using APR-util brigade
1325 helper functions and relying on current filter assumptions.
1328 Changes with Apache 2.0.39
1330 *) Fixed a build problem in htpasswd.c on Win32.
1331 [Guenter Knauf <eflash@gmx.net>, Cliff Woolley]
1333 Changes with Apache 2.0.38
1335 *) Rewrite htpasswd to use APR. The removes the annoying warning about
1336 tmpnam being unsafe. [Ryan Bloom]
1338 *) We must set the MIME-type for .shtml files to text/html if we want them
1339 to be parsed for SSI tags. Add the config for that to the default
1340 config file so that it is easier to enable .shtml parsing.
1341 [Dave Dyer <ddyer@real-me.net>]
1343 *) Fixed a problem with 'make install' on ReliantUnix.
1344 [Jean-frederic Clere <jfrederic.clere@fujitsu-siemens.com>]
1346 *) Make the default_handler catch all requests that aren't served by
1347 another handler. This also gets us to return a 404 if a directory
1348 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1349 loaded. [Justin Erenkrantz]
1351 *) Fixed the handling of nested if-statements in shtml files.
1352 PR 9866 [Brian Pane]
1354 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1355 into a directory different from the one that was configured. This
1356 also mirrors the root= feature from 1.3. We cannot use prefix=,
1357 because both APR and APR-util resolve their installation paths at
1358 configuration time. This means that there is no variable prefix
1359 to replace. [Andreas Hasenack <andreas@netbank.com.br>]
1361 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1362 These levels of AIX don't have a thundering herd problem with
1363 accept(). [Jeff Trawick]
1365 *) prefork MPM: Ignore mutex errors during graceful restart. For
1366 certain types of mutexes (particularly SysV semaphores), we
1367 should expect to occasionally fail to obtain or release the
1368 mutex during restart processing. [Jeff Trawick]
1370 *) Fix install-bindist.sh so that it finds any perl instead of just
1371 early perl 5.x versions. This is consistent with a build/install
1372 from source, and it allows the perl scripts installed by a bindist
1373 to work on systems with perl 5.6. [Jeff Trawick]
1375 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
1376 Tru64 (and probably some other platforms). [Jeff Trawick]
1378 *) Allow CGI scripts to return their Content-Length. This also fixes a
1379 hang on HEAD requests seen on certain platforms (such as FreeBSD).
1382 *) Added log rotation based on file size to the RotateLog support
1383 utility. [Brad Nicholes]
1385 *) Fix some casting in mod_rewrite which broke random maps.
1386 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
1388 Changes with Apache 2.0.37
1390 *) allow POST method over SSL when per-directory client cert
1391 authentication is used with 'SSLOptions +OptRenegotiate' enabled
1392 and a client cert was found in the ssl session cache.
1394 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
1395 session cache when there is no cert chain in the cache. prior to
1396 the fix this situation would result in a FORBIDDEN response and
1397 error message "Cannot find peer certificate chain"
1400 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
1401 one was already sent. PR 9644 [Jeff Trawick]
1403 *) Fix the display of the default name for the mime types config
1404 file. PR 9729 [Matthew Brecknell <mbrecknell@orchestream.com>]
1406 *) Fix the working directory *for WinNT/2K/XP services only* to
1407 change to the Apache directory (one level above the location
1408 of Apache.exe, in the case that Apache.exe resides in bin/.)
1409 Solves the case of ServerRoot /foo paths where /foo was not
1410 on the same drive as /winnt/system32. [William Rowe]
1412 *) Make 2.0's "AcceptMutex" startup message now "completely"
1413 match how 1.3 does it. [Jim Jagielski]
1415 *) Implement a fixed size memory cache using a priority queue
1418 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
1419 querying certain other variables from config_vars.mk. PR 9316
1422 *) Added the "detached" attribute to the cgi_exec_info_t internals
1423 so that Win32 and Netware won't create a new window or console
1424 for each CGI invoked. PR 8387
1425 [Brad Nicholes, William Rowe]
1427 *) Consolidated the command line parameters and attributes that are
1428 manipulated by the optional function ap_cgi_build_command() in
1429 mod_cgi into a single structure.
1432 *) Get rid of uninitialized value errors with "apxs -q" on certain
1433 variables. [Stas Bekman <stas@stason.org>]
1435 *) Fix apxs to allow it to work when the build directory is somewhere
1436 besides server-root/build. PR 8453
1437 [Jeff Trawick and a host of others]
1439 *) Allow ap_discard_request_body to be called multiple times in the
1440 same request. Essentially, ap_http_filter keeps track of whether
1441 it has sent an EOS bucket up the stack, if so, it will only ever
1442 send an EOS bucket for this request.
1443 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
1445 *) Remove all special mod_ssl URIs. This also fixes the bug where
1446 redirecting (.*) will allow an SSL protected page to be viewed
1447 without SSL. [Ryan Bloom]
1449 *) Fix the binary build install script so that the build logic
1450 created by "apxs -g" will work when the user has a binary
1451 build. [Jeff Trawick]
1453 *) Allow instdso.sh to work with full paths to the shared module.
1456 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
1457 in module for NetWare [Brad Nicholes]
1459 *) Changed cgi and piped log behavior to accept 65536 characters
1460 on Win32 (matching Linux) before deadlocking between outputing
1461 client stdin, slurping the output from stdout and then the stderr
1462 stream. PR 8179 [William Rowe]
1464 *) Fixed Win32 wintty.exe support to assure the window title is valid.
1465 Elimiates possible gpfault or garbage title without the -t option.
1468 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
1469 brigades and input filters. [Justin Erenkrantz]
1471 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
1472 body. [Justin Erenkrantz]
1474 *) NetWare: Piping log entries through RotateLogs using the
1475 CustomLogs directive is finally supported now that we have
1476 the pipes and spawning functionality working.
1479 *) SECURITY [CVE-2002-0392] (cve.mitre.org) [CERT VU#944335]:

1486 *) Correctly return 413 when an invalid chunk size is given on
1487 input. Also modify ap_discard_request_body to not do anything
1488 on sub-requests or when the connection will be dropped.
1491 *) Fix the TIME_* SSL var lookups to be threadsafe. PR 9469.
1494 *) Ensure that apr_brigade_write() flushes in all of the cases that
1495 it should to avoid conditions in some modules that could cause
1496 large amounts of data to be buffered. [Cliff Woolley]
1498 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
1499 stripping the content_type from cached responses.
1502 *) apachectl passes through any httpd options. Note: apachectl
1503 should be used in preference to httpd since it ensures that any
1504 appropriate environment variables have been set up.
1507 *) Fix the combination of mod_cgid, mod_setuexec, and mod_userdir.
1508 PR 7810 [Colm MacCarthaigh <colmmacc@redbrick.dcu.ie>]

1525 [Yoshiki Hayashi, Joshua Slive]
1527 *) Fix a file permissions problem which prevented mod_disk_cache
1528 from working on Unix. [Jeff Trawick]
1530 *) Add "-k start|restart|graceful|stop" support to httpd for the Unix
1531 MPMs. These have semantics very similar to the old apachectl
1532 commands of the same name. [Justin Erenkrantz, Jeff Trawick]

1549 *) The APLOG_NOERRNO flag to ap_log_[r]error() is now deprecated.
1550 It is currently ignored and it will be removed in a future release
1551 of Apache. [Jeff Trawick]
1553 *) Removed documentation references to the no-longer-supported
1554 "make certificate" feature of mod_ssl for Apache 1.3.x. Test
1555 certificates, if truly desired, can be generated using openssl
1556 commands. PR 8724. [Cliff Woolley]
1558 *) Remove SSLLog and SSLLogLevel directives in favor of having
1559 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
1561 *) OS/390: LIBPATH no longer has to be manually uncommented in
1562 envvars to get apachectl to set up httpd properly. [Jeff Trawick]
1564 *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
1565 may now be specified to the <File/Directory > container, rather
1566 than by vhost. [William Rowe]
1568 *) mod_isapi: Experimental support for faux async support for ISAPI
1569 modules. [William Rowe]
1571 *) mod_isapi: Major refactoring of the code to rely on apr internals
1572 rather than MS APIs (using our own mod_isapi.h headers for ISAPI
1573 symbol definitions.) [William Rowe]
1575 *) mod_isapi: Fixed the return string length from GetServerVariable
1576 callback, it was not including the trailing null in the consumed

1730 ap_uname2id. [Scott Lamb <slamb@slamb.org>]
1732 *) Fix AcceptPathInfo. PR 8234 [Cliff Woolley]
1734 *) SECURITY: Added the APLOG_TOCLIENT flag to ap_log_rerror() to
1735 explicitly tell the server that warning messages should be sent
1736 to the client in addition to being recorded in the error log.
1737 Prior to this change, ap_log_rerror() always sent warning
1738 messages to the client. In one case, a faulty CGI script caused
1739 the server to send a warning message to the client that contained
1740 the full path to the CGI script. This could be considered a
1741 minor security exposure. [Bill Stoddard]
1743 *) mod_autoindex output when SuppressRules was specified would
1744 omit the first carriage return so the first item in the list
1745 would appear to the right of the column headings instead of
1746 underneath them. PR 8016 [David Shane Holden <dpejesh@yahoo.com>]
1748 *) Moved the call to apr_mmap_dup outside the error branch so
1749 that it would actually get called. This fixes a core dump
1750 at init everytime you use the MMapFile directive. PR 8314
1753 *) Trigger an error when a LoadModule directive attempts to
1754 load a module which is built-in. This is a common error when
1755 switching from a DSO build to a static build. [Jeff Trawick]
1757 *) Change instdso.sh to use libtool --install everywhere and then
1758 clean up some stray files and symlinks that libtool leaves around
1759 on some platforms. This gets subversion building properly since
1760 it needed a re-link to be performed by libtool at install time,
1761 and the old instdso.sh logic to simply cp the DSO didn't handle
1762 that requirement. [Sander Striker]

1773 *) Fix segfault in mod_mem_cache when garabge collecting an expired
1774 cache entry. [Bill Stoddard]
1776 *) Introduced -E startup_logfile_name option to httpd to allow admins
1777 to begin logging errors immediately. This provides Win32 users
1778 an alternative to sending startup errors to the event viewer, and
1779 allows other daemon tool authors an alternative to logging to stderr.

1864 *) Fixes for mod_include errors on boundary conditions in which
1865 "<!--#" occurs at the very end of a bucket
1866 [Paul Reder, Brian Pane]
1868 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
1869 cause the Apache parent process to run in the foreground (similar to
1870 -DNO_DETACH except that it doesn't switch session ids).
1873 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
1874 for those platforms that support it. If using the default
1875 implementation, this is between pthread and sysvsem in priority.
1876 This implies it's the new default for Darwin. [Jim Jagielski]
1878 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
1879 environment variables in the envvars file. [Jeff Trawick]
1881 *) worker MPM: Don't create a listener thread until we have a worker
1882 thread. Otherwise, in situations where we'll have to wait a while
1883 to take over scoreboard slots from a previous generation, we'll be
1884 accepting connections we can't process yet. [Jeff Trawick]
1886 *) Allow worker MPM to build on systems without pthread_kill().
1887 [Pier Fumagalli, Jeff Trawick]
1889 *) Prevent ap_add_output_filters_by_type from being called in

1909 *) Update mod_cgid to not do single-byte socket reads for CGI headers
1912 *) Made AB's use of the Host: header rfc2616 compliant
1913 by Taisuke Yamada <tai@iij.ad.jp> [Dirk-Willem van Gulik].
1915 *) The old, legacy (and unused) code in which the scoreboard was totally
1916 and completely contained in a file (SCOREBOARD_FILE) has been
1917 removed. This does not affect scoreboards which are *mapped* to
1918 files using named-shared-memory. [Jim Jagielski]
1920 *) Change bucket brigades API to allow a "bucket allocator" to be
1921 passed in at certain points. This allows us to implement freelists
1922 so that we can stop using malloc/free so frequently.
1923 [Cliff Woolley, Brian Pane]
1925 *) Add support for macro expansion within the variable names in
1926 <!--#echo--> and <!--#set--> directives [Brian Pane]

1939 several problems with how quick handlers work with subrequests.
1942 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]

1953 [Linus Walleij <triad@df.lth.se>, Justin Erenkrantz]
1955 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
1957 *) When a proxied site was being served, Apache was replacing
1958 the original site Server header with it's own, which is not
1959 allowed by RFC2616. Fixed. [Graham Leggett]
1961 *) Fix a mod_cgid problem that left daemon processes stranded
1962 in some server restart scenarios. [Jeff Trawick]
1964 *) Added exp_foo and rel_foo variables to config_vars.mk for
1965 all Apache and Autoconf path variables (like --sysconfdir,
1966 --sbindir, etc). exp_foo is the "expanded" version, which means
1967 that all internal variable references have been interpolated.
1968 rel_foo is the same as $exp_foo, only relative to $prefix if they
1969 share a common path. [Aaron Bannert]
1971 *) Fix some restart/terminate problems in the worker MPM. Don't
1972 drop connections during graceful restart. [Jeff Trawick]
1974 *) Change the header merging behaviour in proxy, as some headers
1975 (like Set-Cookie) cannot be unmerged due to stray commas in
1976 dates. [Graham Leggett]
1978 *) Be more vocal about what AcceptMutex values we allow, to make
1979 us closer to how 1.3 does it. [Jim Jagielski]

1984 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
1986 *) Add accessor function to set r->content_type. From now on,
1987 ap_rset_content_type() should be used to set r->content_type.
1988 This change is required to properly implement the
1989 AddOutputFilterByType configuration directive.
1990 [Bill Stoddard, Sander Striker, Ryan Bloom]

1998 *) Fix for virtual host processing where the requested hostname
1999 has a '.' at the end (PR 9187) [Ryan Cruse <ryan@estara.com>]
2001 *) mod_dav's APIs for REPORT response handling was changed so that
2002 providers can generate the content directly into the output filter
2003 stack, rather than buffering the response into memory. [Greg Stein]
2005 *) Fix a hang condition with graceful restart and prefork MPM
2006 in the situation where MaxClients is very high but
2007 much fewer servers are actually started at the time of the
2008 restart. [Jeff Trawick]
2010 *) Small performance fixes for mod_include [Brian Pane]
2012 *) Performance improvement for the error logger [Brian Pane]
2014 *) Change configure so that Solaris 8 and above have
2015 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
2016 according to sun people solaris 8+ doesn't have a thundering
2017 herd problem [Ian Holsman]
2019 *) Allow URIs specifying CGI scripts to include '/' at the end

2035 *) Fix the calculation of thread_num in the worker score structure.
2038 *) Use apr_atomic operations in managing the mod_mem_cache
2039 cache_objects for SMP scalability. (see USE_ATOMICS
2040 preprocessor directive in mod_file_cache)
2043 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
2044 preprocessor directive in mod_file_cache)

2050 *) Add a missing manualdir entry in the Debian config.layout.
2051 [Thom May <thom@planetarytramp.net>]
2053 *) Stop installing libtool for APR and tell APR where it should place
2054 its copy of libtool (via our installbuildpath layout variable).
2057 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
2058 when reading from a remote HTTP server in proxy. [Graham Leggett]
2060 *) Modify receive/send loop in proxy_http and proxy_ftp so that
2061 should it be necessary, the remote server socket is closed before
2062 transmitting the last buffer (set by ProxyIOBufferSize) to the
2063 client. This prevents the backend server from being forced to hang
2064 around while the last few bytes are transmitted to a slow client.
2065 Fix the case where no error checking was performed on the final
2066 brigade in the loop. [Graham Leggett]
2068 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
2069 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
2070 hours. [Graham Leggett, Bill Stoddard]
2072 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
2073 for a undefined variable. [Ian Holsman]
2075 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
2076 when we can't get a socket in the specified address family. We may
2077 have gotten back an IPv6 address first and yet our system is not
2078 configured to allow IPv6 sockets. [Jeff Trawick]
2080 *) Be more careful about recursively removing CVS directories. Make
2081 sure that we aren't cd'ing to their home directory first. PR: 9993
2082 [Aaron Bannert, James LewisMoss <dres@lewismoss.net>]

2085 [Dirk-Jan Faber <dirk-jan@selwerd.nl>, Aaron Bannert,
2086 Thom May <thom@planetarytramp.net>]
2088 *) Rename the filter ordering priorities. The recent filtering fixes
2089 have showcased problems with their usage. Therefore, we need to
2090 rename them to increase the clarity. (CONTENT->RESOURCE,
2091 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
2093 Changes with Apache 2.0.33
2095 *) Fix a problem in the new --enable-layout functionality where
2096 it wouldn't allow overrides from variables like --prefix,
2097 --bindir, etc. [Thom May <thom@planetarytramp.net>]
2099 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
2100 no longer hangs around waiting for the socket to close before
2101 returning exhaustive data. [Aaron Bannert]
2103 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
2104 [Thom May <thom@planetarytramp.net>]
2106 *) Change mod_ssl to always do a full startup/teardown on restarts.
2107 this allows mod_ssl to be added to a server that is already
2108 running and makes it possible to add/change certs/keys after the
2109 server has been started. [Doug MacEachern]
2111 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
2112 This pipe must be a bidirectional 'console' style relay, which
2113 mod_ssl prints all prompts to the pipe's stdin, and reads the
2114 passphrases from the pipe's stdout. [William Rowe]
2116 *) Fix bug where --sysconfdir and --localstatedir were being
2117 ignored. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
2120 *) Fix --enable-layout to work again. Caution: When specifying
2121 --enable-layout, common arguments like --prefix, --exec-prefix,
2122 etc. will be ignored and the settings from the layout will be
2123 used instead. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
2126 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
2127 regex pattern matching for the determination of which requests
2128 to use the remote proxy for. [Jim Jagielski]
2130 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
2132 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
2133 cruft in piped logs and rewritemap child processes.
2136 *) All instances of apr_lock_t have been removed and converted
2137 to one of the following new lock APIs: apr_thread_mutex.h,
2138 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
2139 use the apr_lock.h API, as the old API will soon be deprecated.
2142 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
2143 [Ralf S. Engelschall, Cliff Woolley]
2145 *) mod-include: make it handle flush'es and fix the 'false-alarm'
2146 [Justin Erenkrantz, Brian Pane, Ian Holsman]
2148 *) ap_get_*_filter_handle() functions to allow 3rd party modules
2149 to lookup filter handles so they can bypass the filter name
2150 lookup when adding filters to a request (via ap_add_*_filter_handle())
2151 [Ryan Morgan <rmorgan@covalent.net>]
2153 *) Fix for multiple file buckets on Win32, where the first file
2154 bucket would cause the immediate closure of the socket on any
2155 non-keepalive requests. [Ryan Morgan <rmorgan@covalent.net>]
2157 *) Correct Win32 failure of mmap of a segment beyond start of the
2158 file; fixes large SSL and similar transfers. [William Rowe]
2161 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
2162 multi-process mode to not "daemonize" while detaching from the
2163 controlling terminal. This is necessary for Apache to work with
2164 process-management tools like AIX's "System Resource Controller"
2165 as well as Dan Bernstein's "daemontools".
2166 [Jos Backus <josb@cncdsl.com>, Aaron Bannert]
2168 *) Convert mod_auth_digest to use the new apr_global_mutex_t
2169 type. [Aaron Bannert]
2171 *) fix bug in mod-include where it wouldn't send a unmatched
2172 part if it was at the end of a bucket [Ian Holsman]
2174 *) worker MPM: Improve logging of errors with the interface between
2175 the listener thread and worker threads. [Jeff Trawick]
2177 *) Some browsers ignore cookies that have been merged into a
2178 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
2179 are now unmerged in the http proxy before being sent to the
2180 client. [Graham Leggett]
2182 *) Fix a problem with proxy where each entry of a duplicated
2183 header such as Set-Cookie would overwrite and obliterate the
2184 previous value of the header, resulting in multiple header
2185 values (like cookies) going missing.
2186 [Graham Leggett, Joshua Slive]
2188 *) Add the server-limit and thread-limit values to the scoreboard

2211 *) Fix segfault and display error when SSLMutex file can not be
2212 created. [Adam Sussman <myddryn@vishnu.vidya.com>]
2214 *) Add reference counting to mod_mem_cache cache objects to
2215 better manage removing objects from the cache.
2218 *) Change the verbage on the ScoreBoardFile in our default configs.
2219 Also change the default to be commented out (unspecified) so we
2220 get anonymous shared memory by default. [Aaron Bannert]
2222 *) Implement new ScoreBoardFile directive logic. This affects how
2223 we create the scoreboard's shared memory segment. If the directive
2224 is present, a name-based segment is created. If the directive is
2225 not present, first an anonymous segment is created, and if that
2226 fails, a name-based segment is created from a file of the name
2227 DEFAULT_SCOREBOARD. This gives third-party applications the
2228 ability to access our scoreboard. [Aaron Bannert]
2230 *) Allow mod_deflate to work with non-GET requests and properly send
2231 Content-Lengths. [Sander Striker <striker@apache.org>]
2233 *) Fix ap_directory_merge() to correctly merge configs when there is
2234 no <Directory /> block. [Justin Erenkrantz, William Rowe]
2236 *) Remove spurious debug messsages that are normal under HTTP
2237 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
2239 *) Fix a bug in mod_cgid that would prevent proper shutdown death
2240 of the cgid process. [Aaron Bannert]
2242 *) Add signal handling back in to the worker MPM for the one_process
2243 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
2245 *) Performance: Reuse per-connection transaction pools in the
2246 worker MPM, rather than destroying and recreating them. [Brian Pane]
2248 *) Remove all signals from the worker MPM's child process. Instead,
2249 the parent uses the Pipe of Death for all communication with the
2250 child processes. [Ryan Bloom]
2252 Changes with Apache 2.0.32
2254 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
2255 default if the directive is not specified. This mirrors older
2256 behavior without changes to the httpd.conf. [William Rowe]
2258 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
2259 the service, mpm and logging code, and bugs in apr_file_open_stderr
2260 and apr_file_dup2 functions. Win2K/XP services have no handles
2261 associated for stdin/out/err, which caused unpredictable behavior
2262 in the prior release. [William Rowe, Bill Stoddard]
2264 *) Win32: simplify the Application Event Log messages, since there isn't
2265 likely to be 'more information in the error log' before an error log
2266 has been opened. [William Rowe]
2268 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
2269 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
2271 *) Win32: apache -k shutdown now behaves like apache -k stop.
2274 *) Fix prefork to not kill the parent if a child hits a resource shortage
2275 on accept(). [Greg Ames]
2277 *) Fix seg faults that occur when what should be the httpd request line
2278 starts with \r\n followed by garbage. [Greg Ames]
2280 *) Allow statically linked support binaries with the new
2281 --enable-static-support flag, and enable this behavior in
2282 the binbuild script. Also add a new --enable-static-htdbm
2283 flag. [Aaron Bannert]
2285 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
2286 do only one stat() call when generating the directory listings.
2289 *) Fix resolve_symlink to save the original symlink name if known.
2292 *) Be a bit more sane with regard to CanonicalNames. If the user has
2293 specified they want to use the CanonicalName, but they have not
2294 configured a port with the ServerName, then use the same port that
2295 the original request used. [Ryan Bloom and Ken Coar]
2297 *) In core_input_filter, check for an empty brigade after
2298 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
2299 client says it will post some data but we get FIN before any
2300 data arrives. [Jeff Trawick]
2302 *) Not being able to bind to the socket is a fatal error. We should
2303 print an error to the console, and return a non-zero status code.
2304 With these changes, all of the Unix MPMs do that correctly.
2307 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
2308 through to CGI scripts. PR 9163
2309 [Brian Reid <breid@customlogic.com>,
2310 Zvi Har'El <rl@math.technion.ac.il>]
2312 *) binbuild.sh: Make sure that we use the expat from our source
2313 tree so that there aren't any surprises on the target machine.
2316 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2317 enough to keep up with new requests. Start using
2318 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2319 when we can't talk to the daemon. [Jeff Trawick]
2321 *) apxs: LTFLAGS envvar can override default libtool options. Try
2322 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2323 the covers. [Jeff Trawick]
2325 *) The Location: response header field, used for external
2326 redirect, *must* be an absoluteURI. The Redirect directive
2327 tested for that, but RedirectMatch didn't -- it would allow
2328 almost anything through. Now it will try to turn an abs_path
2329 into an absoluteURI, but it will correctly varf like Redirect
2330 if the final redirection target isn't an absoluteURI. [Ken Coar]
2332 Changes with Apache 2.0.31
2334 *) Create the scoreboard (in the parent) in a global pool context,
2335 so it survives graceful restarts. This fixes a SEGV during
2336 graceful restarts. [Aaron Bannert]
2338 *) Add a timeout option to the proxy code 'ProxyTimeout'
2341 *) FTP directory listings are now always retrieved in ASCII mode.
2342 The FTP proxy properly escapes URI's and HTML in the generated
2343 listing, and escapes the path components when talking to the FTP
2344 server. It is now possible to browse the root directory by using
2345 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2346 Also, the last path component may contain wildcard characters
2347 '*' and '?', and if they do, a directory listing is created instead
2348 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2351 *) Added single-listener unserialized accept support to the
2352 worker MPM [Brian Pane]
2354 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2355 the incoming host header through to the proxied server
2356 [Geoff <g.russell@ieee.org>]
2358 *) New Directive Option for ProxyPass. It now can block a location
2359 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
2361 *) Don't let the default handler try to serve a raw directory. At
2362 best you get gibberish. Much worse things can happen depending
2363 on the OS. [Jeff Trawick]
2365 *) Change the pre_config hook to return a value. Modules can now emit
2366 an error message and then cause the server to quit gracefully during
2367 startup. This required a bump to the MMN. [Aaron Bannert]
2369 *) Fix some unix socket descriptor leaks in the handler side of
2370 mod_cgid (the part that runs in the server process). Whack a
2371 silly "close(-1)" in the handler too. [Jeff Trawick]
2373 *) Change the pre_mpm hook to return a value, so that scoreboard
2374 init errors percolate up to code that knows how to exit
2375 cleanly. This required a bump to the MMN. [Jeff Trawick]
2377 *) Add the socket back to the conn_rec and remove the create_connection
2378 hook. The create_connection hook had a design flaw that did not
2379 allow creating connections based on vhost info. [Bill Stoddard]
2381 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2382 Resolves the common case of using negotation to resolve the request
2383 /script/foo for /script.cgi/foo. [William Rowe]
2385 *) Added new functions ap_add_(input|output)_filter_handle to
2386 allow modules to bypass the usual filter name lookup when
2387 adding hard-coded filters to a request [Brian Pane]
2389 *) caching should now work on subrequests (still very experimental)
2392 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2394 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2397 *) Refactor ap_rgetline so that it does not use an internal brigade.
2398 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2400 *) Remove mod_auth_db. [Justin Erenkrantz]
2402 *) Do not install unnecessary pcre headers like config.h and internal.h.
2403 [Joe Orton <joe@manyfish.co.uk>]
2405 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
2406 (as it does for a normal request). quick_handled sub-requests now work
2407 in mod-include [Ian Holsman]
2409 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
2410 'CONTENT' one, as it needs to run AFTER all content headers
2412 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
2415 *) Split out blocking from the mode in the input filters.
2418 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
2420 *) Cause Win32 to capture all child-worker process errors in
2421 Apache to the main server error log, until the child can
2422 open its own error logs. [William Rowe]
2424 *) HPUX 11.*: Do not kill the child process when accept()
2425 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
2426 by [madhusudan_mathihalli@hp.com])
2429 *) Fix a problem in the parsing of the <Proxy foo> directive.
2432 *) rewrite of mod_ssl input filter for better performance and less
2433 memory usage [Doug MacEachern]
2435 *) allow quick_handler to be run on subrequests. [Ian Holsman]
2437 *) mod_dav now asks its provider to place content directly into the
2438 filter stack when handling a GET request. The mod_dav/provider
2439 API has changed, so providers need to be updated. [Greg Stein]
2441 *) Clear the output socket descriptor in unixd_accept() to make sure
2442 we don't supply a bogus socket to the caller if the accept fails.
2443 This caused problems with the worker MPM, which tried to process
2444 the returned socket if it was non-NULL. [Brian Pane]
2446 *) Move a check for an empty brigade to the start of core input filter
2447 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
2449 *) Add FileETag directive to allow configurable control of what
2450 data are used to form ETag values for file-based URIs. MMN
2451 bumped to 20020111 because of fields added to the end of
2452 the core_dir_config structure. [Ken Coar]
2454 *) Fix a segfault in mod_rewrite's logging code caused by passing the
2455 wrong config to ap_get_remote_host(). [Jeff Trawick]
2457 *) Allow mod_cgid to work from a binary distribution install by
2458 using 755 for the permissions on the log directory instead of
2461 *) Fixed a segfault that happened during graceful shutdown (or when
2462 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
2464 *) Split all Win32 modules [excluding the core components mod_core,
2465 mod_so, mod_win32 and the winnt mpm] into individual loadable
2466 modules, so the administrator may individually disable the former
2467 compiled-in modules by simply commenting out their LoadModule
2468 directives. [William Rowe]
2470 *) Saved Win32 module authors and porters many future headaches, by
2471 duplicating the appropriate .h files such as os.h into the include
2472 directory, including in the build tree. [William Rowe]
2474 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
2475 Use SSL functions/macros instead of directly dereferencing SSL
2476 structures wherever possible.
2477 Add type-casts for the cases where functions return a generic pointer.
2478 Add $SSL/include to configure search path.
2479 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2481 *) Moved several pointers out of the shared Scoreboard so it is
2482 more portable, and will present the vhost name across server
2483 generation restarts. [William Rowe]
2485 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
2488 Changes with Apache 2.0.30
2490 *) Fix the main bug for FreeBSD and threaded MPM's. There are
2491 still issues (see STATUS) but at least the server will now
2492 run without crashing the machine.
2493 [David Reid, Aaron Bannert, Justin Erenkrantz]
2495 *) Fix a typo in mod_deflate's m4 config section.
2496 [albert chin (china@thewrittenword.com)]
2498 *) Fix a couple of mod_proxy problems forwarding HTTP connections
2499 and handling CONNECT:
2500 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
2501 (2) Proxy failed to connect when the first IP address returned by
2502 the resolver was unreachable but a secondary IP address was.
2505 *) Fix the module identifer as shown in the docs for various core
2506 modules (e.g., the identifer for mod_log_config was previously
2507 listed as config_log_module). PR #9338
2508 [James Watson <ap2bug@sowega.org>]
2510 *) Fix LimitRequestBody directive by placing it in the HTTP
2511 filter. [Justin Erenkrantz]
2513 *) Fix mod_proxy seg fault when the proxied server returns
2514 an HTTP/0.9 response or a bogus status line.
2517 *) Prevent mod_proxy from truncating one character off the
2518 end of the status line returned from the proxied server.
2519 [Adam Sussman, Bill Stoddard]
2521 *) Eliminate loop in ap_proxy_string_read().
2522 [Adam Sussman, Bill Stoddard]
2524 *) Provide $0..$9 results from mod_include regex parsing.
2527 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
2529 *) Introduced the ForceLanguagePriority directive, to prevent
2530 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
2531 when using Multiviews. [William Rowe]
2533 *) Fix a problem which prevented mod_cgid and suexec from working
2534 together reliably [Greg Ames]
2536 *) Remove the call to exit() from within mod_auth_digest's post_config
2537 phase. [Aaron Bannert]
2539 *) Fix a problem in mod_auth_digest that could potentially cause
2540 problems with initialized static data on a system that uses DSOs.
2543 *) Fix a segfault in the worker MPM that could happen during
2544 child process exits. [Brian Pane, Aaron Bannert]
2546 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
2548 *) Fix matching of vhosts by ip address so we find IPv4
2549 vhost address when target address is v4-mapped form of
2550 that address. [Jeff Trawick]
2552 *) More performance tweaks to the BNDM string-search algorithm
2553 used to find "<!--#" tokens in mod_include [Brian Pane]
2555 *) Miscellaneous small performance fixes: optimized away various
2556 string copy operations and removed large temp buffers from
2557 the stack [Brian Pane]
2559 *) Fixed startup segfault that occurred when a VirtualHost
2560 directive had a port but no address [Brian Pane]
2562 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
2564 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
2565 if oslevel < WINNT. This should fix several problems reported
2566 Against 2.0.28 on Windows 98 [Bill Stoddard]
2568 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
2569 to fail. [Bill Stoddard]
2571 *) Change core code to allow an MPM to set hard thread/server
2572 limits at startup. prefork, worker, and perchild MPMs now have
2573 directives to set these limits. [Jeff Trawick]
2575 *) Win32: The async AcceptEx() event should be autoreset upon
2576 successful completion of a wait (WaitForSingleObject). This
2577 eliminates a number of spurious
2578 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
2581 *) Move any load library path environment variables out of
2582 apachectl and into a separate environment variable file which
2583 can be more easily tailored by the admin. The environment
2584 variable file as built by Apache may have additional system-
2585 specific settings. For example, on OS/390 we tailor the heap
2586 settings to allow lots of threads. [Jeff Trawick]
2588 *) Use the new APR pool code to reduce pool-related lock
2589 contention in the worker MPM. [Sander Striker]
2591 *) The POD no longer assumes the child is listening on 127.0.0.1
2592 and now pulls the first hostname in the list of listeners to
2593 perform the dummy connect on. This fixes a bug when the user
2594 had configured the Listen directive for an IP other than
2595 127.0.0.1. This would result in undead children and error
2596 messages such as "Connection refused: connect to listener".
2599 *) The worker MPM now respects the LockFile setting, needed to
2600 avoid locking problems with NFS. [Jeff Trawick]
2602 *) Fix segfault when worker MPM receives SIGHUP.
2603 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
2605 *) Fix bug that could potentially prevent the perchild MPM from
2606 working with more than one vhost/uid. [Aaron Bannert]
2608 *) Change make install and apxs -i processing of DSO modules to
2609 perform special handling on platforms where libtool doesn't install
2610 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
2611 which prevented standard LoadModule statements from working.
2614 *) Whenever mod_so is enabled (not just when there are DSOs for
2615 our modules), do whatever special magic is required for compiling/
2616 loading third-party modules. This allows third-party DSOs to
2617 be used on an AIX build when there were no built-in modules
2618 built as DSOs. (This should help on OS/390 and BeOS as well.)
2621 *) Allow apxs to be used to build DSOs on AIX without requiring the
2622 user to hard-code the list of import files. (This should help
2623 on OS/390 and BeOS as well.) [Jeff Trawick]
2625 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
2626 PR 8563, 8919 [William Rowe]
2628 *) Get binary builds working when libapr and libaprutil are built
2631 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
2632 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
2633 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
2635 *) Fix the handling of SSI directives in which the ">" of the
2636 terminating "-->" is the last byte in a file [Brian Pane]
2638 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
2639 message that we had back in apache-1.3 and still have scattered
2640 throughout our docs. [Aaron Bannert]
2642 *) Prevent the Win32 port from continuing after encountering an
2643 error in the command line args to apache. [William Rowe]
2645 *) On a error in the proxy, make it write a line to the error log
2648 *) Various mod_ssl performance improvements [Doug MacEachern]
2650 Changes with Apache 2.0.29
2652 *) Add buffering in core_output_filter to ensure that long
2653 lists of small buckets don't cause small packet writes.
2654 [Brian Pane, Ryan Bloom]
2656 *) Fix the installation target to make sure that the manual is
2657 installed in the correct location.
2658 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
2659 Gomez Henri <hgomez@slib.fr>]
2661 *) Fix the cmd command for mod_include. When we are processing
2662 a cmd command, we do not want to use the r->filename to set
2663 the command name. The command comes from the SSI tag. To do this,
2664 I added a variable to the function that builds the command line
2665 in mod_cgi. This allows the include_cmd function to specify
2666 the command line itself. [Ryan Bloom]
2668 *) Change open_logs hook to return a value, allowing you
2669 to flag a error while opening logs
2670 [Ian Holsman, Doug MacEachern]
2672 *) Change post_config hook to return a value, allowing you
2673 to flag a error post config
2674 [Ian Holsman, Jeff Trawick]
2676 *) Allow SUEXEC_BIN (the path to the suexec binary that is
2677 hard-coded into the server) to be specified to the configure
2678 script by the --with-suexec-bin parameter. [Aaron Bannert]
2680 *) Fix segv in worker MPM following accept on pipe-of-death
2683 *) Add mod_deflate to experimental.
2684 [Ian Holsman, Justin Erenkrantz]
2686 *) Bail out at configure time if an invalid MPM was specified.
2687 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2689 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
2690 configured [John Sterling <sterling@covalent.net>]
2692 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
2694 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
2696 *) Optimization for the BNDM string-search function in
2697 mod_include. [Brian Pane]
2699 *) Fixed the behavior of the XBitHack directive.
2700 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
2702 *) The threaded MPM for Unix has been removed. Use the worker
2703 MPM instead. [various]
2705 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
2706 in logging the error from a failed DNS lookup. [Jeff Trawick]
2708 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
2711 *) Get mod_cgid killed when a MPM exits due to a fatal error.
2714 *) Fix a file descriptor leak in mod_include. When we include a
2715 file, we use a sub-request, but we didn't destroy the sub-request
2716 immediately, instead we waited until the original request was
2717 done. This patch closes the sub-request as soon as the data is
2718 done being generated. [Brian Pane <bpane@pacbell.net>]
2720 *) Allow modules that add sockets to the ap_listeners list to
2721 define the function that should be used to accept on that
2722 socket. Each MPM can define their own function to use for
2723 the accept function with the MPM_ACCEPT_FUNC macro. This
2724 also abstracts out all of the Unix accept error handling
2725 logic, which has become out of synch across Unix MPMs.
2728 *) Fix a bug which would cause the response headers to be omitted
2729 when sending a negotiated ErrorDocument because the required
2730 filters were attached to the wrong request_rec.
2731 [John Sterling <sterling@covalent.net>]
2733 *) Remove commas from the end of the macros that define
2734 directives that are used by MPMs. Prior to this patch,
2735 you would use these macros without commas, which was unlike
2736 the macros for any other directives. Now, the caller provides
2737 the comma rather than the macro providing it. This makes
2738 the macros look more like the rest of the directives.
2739 [Ryan Bloom and Cliff Woolley]
2741 *) Add 'redirect-carefully' environment option to disable sending
2742 redirects under special circumstances. This is helpful for
2743 Microsoft's WebFolders when accessing a directory resource via
2744 DAV methods. [Justin Erenkrantz]
2746 *) Begin to abstract out the underlying transport layer.
2747 The first step is to remove the socket from the conn_rec,
2748 the server now lives in a context that is passed to the
2749 core's input and output filters. This forces us to be very
2750 careful when adding calls that use the socket directly,
2751 because the socket isn't available in most locations.
2754 *) Really reset the MaxClients value in worker and threaded
2755 when the configured value is not a multiple of the number
2756 of threads per child. We said we did previously but we
2757 forgot to. [Jeff Trawick]
2759 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
2761 *) If shared modules are requested and mod_so is not available,
2762 produce a fatal config-time error. [Justin Erenkrantz]
2764 *) Improve http2env's performance by cutting the work it has to
2765 do. [Brian Pane <bpane@pacbell.net>]
2767 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
2768 [Brian Pane <bpane@pacbell.net>]
2770 Changes with Apache 2.0.28
2772 *) Fix infinite loop in mod_cgid.c.
2773 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
2775 *) When no port is given in a "ServerName host" directive, the
2776 server_rec->port is now set to zero, not 80. That allows for
2777 run-time deduction of the correct server port (depending on
2778 SSL/plain, and depending also on the current setting of
2779 UseCanonicalName). This change makes redirections
2780 work, even with https:// connections. As in Apache-1.3, the
2781 connection's actual port number is never used, only the ServerName
2782 setting or the client's Host: setting. Documentation updated
2783 to reflect the change. [Martin Kraemer]
2785 *) Add a '%{note-name}e' argument to mod-headers, which works in
2786 the same way as mod_log_confg. [Ian Holsman]
2788 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
2789 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
2790 MPMs. [Cliff Woolley]
2792 *) Introduce htdbm, a user management utility for db/dbm authorization
2793 databases. [Mladen Turk <mturk@mappingsoft.com>]
2795 *) Optimize usage of strlen and strcat in ap_directory_walk.
2796 [Brian Pane <bpane@pacbell.net>]
2798 Changes with Apache 2.0.27
2800 *) Introduce an Apache mod_ssl initial configuration template
2801 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
2803 *) Fixed a memory leak in the getline parsing code that could
2804 be triggered by arbitrarily large header lines. Requests
2805 from the core input filter for single lines are now limited
2806 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
2808 *) Fix a truncation bug in how we print the port on the Via: header.
2809 The routine that prints the Via: header now takes a length for
2810 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
2812 *) Some syntax errors in mod_mime_magic's magic file can result
2813 in a 500 error, which previously was unlogged. Now we log the
2814 error. [Jeff Trawick]
2816 *) Add the support/checkgid helper app, which checks the run-time
2817 validity of group identifiers usable in the Group directive.
2820 *) Various --enable-so options have been fixed: --enable-so is
2821 treated as "static"; explicit --enable-so=shared issues an error;
2822 and explicit --enable-so fails with error on systems without
2823 APR_HAS_DSO. [Aaron Bannert]
2825 *) Fix a segfault in the core input filter when the client socket
2826 gets disconnected unexpectedly. [Cliff Woolley]
2828 *) Fix the reporting for child processes that die. This removes
2829 all of the non-portable W* macros from Apache.
2830 [Jeff Trawick and Ryan Bloom]
2832 *) Win32: Track and display "Parent Server Generation:" in
2833 mod_status output. The generation will be bumped at
2834 server graceful restart, when the child process exits
2835 by hitting MaxRequestsPerChild or if the child
2836 process exits abnormally. [Bill Stoddard]
2838 *) Win32: Fix problem where MaxRequestsPerChild directive was
2839 not being picked up in favor of the default. Enable
2840 the parent to start up a new child process immediately upon
2841 the old child starting shutdown.
2844 *) Fix some bungling of the remote port in rfc1413.c so that
2845 IdentityCheck retrieves the proper user id instead of failing
2846 and thus always returning "nobody."
2847 [Dick Streefland <Dick.Streefland@xs4all.nl>]
2849 *) Introduced thread saftey for mod_rewrite's internal cache.
2850 [Brian Pane <bpane@pacbell.net>]
2852 *) Simplified mod_env's directives to behave as most directives are
2853 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
2854 directive following that UnsetEnv within the same container.
2855 Also provides a runtime startup warning if a PassEnv configured
2856 environment value is undefined. [William Rowe]
2858 *) The worker MPM is now completely ported to APR's new lock API. It
2859 uses native APR types for thread mutexes, cross-process mutexes,
2860 and condition variables. [Aaron Bannert]
2862 *) Sync up documentation to remove all references to the now deprecated
2863 Port directive. [Justin Erenkrantz]
2865 *) Moved all ldap modules from the core to httpd-ldap sub-project
2868 *) Exit when we can't listen on any of the configured ports. This
2869 is the same behavior as 1.3, and it avoids having the MPMs to
2870 deal with bogus ap_listen_rec structures. [Jeff Trawick]
2872 *) Cleanup the proxy code that creates a request to the origin
2873 server. This change adds an optional hook, which allows modules
2874 to gain control while the request is created if the proxy module
2875 is loaded. The purpose of this hook is to allow modules to add
2876 input and/or output filters to the request to the origin. While
2877 I was at it, I made the core use this hook, so that proxy request
2878 creation uses some of the code from the core. This can still be
2879 greatly improved, but this is a good start. [Ryan Bloom]
2881 Changes with Apache 2.0.26
2883 *) Port the MaxClients changes from the worker MPM to the threaded
2886 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
2887 with the new input filtering system. [Justin Erenkrantz]
2889 *) Introduce the MultiviewsMatch directive, to allow the operator
2890 to be flexible in recognizing Handlers and Filters filename
2891 extensions as part of the Multiviews matching logic, strict with
2892 MultiviewsMatch NegotiatedOnly to accept only filename extentions
2893 that designate negotiated parameters, (content type, charset, etc.)
2894 or MultiviewsAll for the 1.3 behavior of matching any files, even
2895 if they have unregistered extensions. [William Rowe]
2897 *) Fixed the configure script to add a LoadModule directive to
2898 the default httpd.conf for any module that was compiled
2899 as a DSO. [Aaron Bannert <aaron@clove.org>]
2901 *) rewrite mod_ssl input filtering to work with the new input filtering
2902 system. [Justin Erenkrantz]
2904 *) prefork: Don't segfault when we are able to listen on some but
2905 not all of the configured ports. [Jeff Trawick]
2907 *) Build mod_so even if no core modules are built shared.
2908 [Aaron Bannert <aaron@clove.org>]
2910 *) Introduce ap_directory_walk rewrite (with further optimizations
2911 required) to adapt to the ap_process_request_internal() changes.
2912 Optimized so subrequests and redirects now reuse previous section
2913 merges, until we mismatch with the original directory_walk, and
2914 precomputed r->finfo results will cause directory_walk to skip
2915 the most expensive phases of the function. [William Rowe]
2917 *) Allow ApacheMonitor to connect to and control Apache on other
2918 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
2920 *) Remove the Port directive. In it's place, the Listen directive
2921 is now a required directive, which tells Apache what port to
2922 listen on. The ServerName directive has also been extended
2923 to accept an optional port. If the port is specified to the
2924 ServerName, the server will report that port whenever it
2925 reports the port that it is listening on. This change was
2926 made to ease configuration errors that stem from having a Port
2927 directive, and a Listen directive. In that situation, the server
2928 would only listen to the port specified by the Listen command,
2929 which caused a lot of confusion to users. [Ryan Bloom]
2931 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
2932 build, as loadable modules. [William Rowe]
2934 *) Fix --enable-mods-shared processing. If most is specified,
2935 then all modules that can be compiled as shared modules are.
2936 [Aaron Bannert <aaron@clove.org>]
2938 *) Update the mime.types file to map video/vnd.mpegurl to mxu
2939 and add commonly used audio/x-mpegurl for m3u extensions.
2940 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
2942 *) Eliminate the depreciated r->content_language, in favor of the array
2943 r->content_languages introduced many years ago. Module authors must
2944 substantially overhaul their modules, so this needs to be upgraded
2945 if the module still relied on backwards-brokeness. [William Rowe]
2947 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
2950 *) Rewrite the input filtering mechanisms to consolidate and reorganize
2951 code. In short, core_input_filter does something now and
2952 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
2954 *) Update the Win32 build to re-absorb mod_proxy and family.
2957 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
2958 current SDK.) [William Rowe]
2960 *) Some style changes to the code that does ProxyErrorOverride. Fixed
2961 config merge behaviour. [Graham Leggett]
2963 *) Allow support programs to be compiled against a static version
2964 of libapr. This allows the smaller support programs to be
2965 relocated. [Aaron Bannert <aaron@clove.org>]
2967 *) Update the mime.types file to the registered media types as
2968 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
2970 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
2971 number of clients that can connect at the same time, instead of
2972 specifying the maximum number of child processes.
2973 [Aaron Bannert <aaron@clove.org>]
2975 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
2976 be consistent with 1.3. [Justin Erenkrantz]
2978 *) Cache apr_explode_localtime() value for 15 seconds.
2979 [Brian Pane <bpane@pacbell.net>]
2981 *) Fix mod_include to not return ETag or Last-Modified headers.
2982 [Ian Holsman <ianh@cnet.com>]
2984 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
2986 *) Eliminate the wasteful run-time conversion of method names from strings
2987 to numbers in places where the methods are known at compile time.
2988 [Brian Pane <bpane@pacbell.net>]
2990 *) Turn the worker MPM's queue into a LIFO. This may
2991 improve cache-hit performance under some conditions.
2992 [Aaron Bannert <aaron@clove.org>]
2994 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
2995 support it. [Justin Erenkrantz]
2997 *) Cleanup the worker MPM. We no longer re-use transaction
2998 pools. This incurs less overhead than shuffling the pools
2999 around so that they can be re-used. Remove one of the
3000 queue's condition variables. We just redefined the API to
3001 state that you can't try to add more stuff than you allocated
3002 segments for. [Aaron Bannert <aaron@clove.org>]
3004 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
3006 *) Fixed persistent connections when a request contains a body.
3009 *) mod_dav uses a new API to speak to the backend provider for dead
3010 property management. [Greg Stein]
3012 *) Remove the Win32 script-processing exception from mod_cgi, and
3013 roll build_command_line/build_argv_list into a unified, overrideable
3014 ap_cgi_build_command optional function. [William Rowe]
3016 *) Rewrite find_start_sequence to use a better search algorithm
3017 to find the start tag. [Justin Erenkrantz]
3019 *) Fix a seg fault in mod_include. When we are generating an
3020 internal redirect, we must set r->uri to "", not a bogus
3021 string, and not NULL. [Ryan Bloom]
3023 *) Optimized location_walk, so subrequests, redirects and second passes
3024 now reuse previous section merges on a <Location > by <Location >
3025 basis, until we mismatch with the original location_walk.
3028 *) Back out the 1.45 change to util_script.c. This change made
3029 us set the environment variable REQUEST_URI to the redirected
3030 URI, instead of the originally requested URI.
3031 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3033 *) Make mod_include do lazy evaluation of potentially expensive to
3034 compute variables. [Brian Pane <bpane@pacbell.net>]
3036 *) Fix logging of bytes sent for HEAD requests. %b and %B should
3037 log either - or 0, before this patch, they were both logging
3038 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3040 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
3041 than per character. [Brian Pane <bpane@pacbell.net>]
3043 *) Normalize the primary request, redirects and sub-requests to
3044 run the same ap_process_request_internal for consistency in
3045 robustness, behavior and security. [William Rowe]
3047 *) Fix a segfault with mod_include when r->path_info is not set
3048 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
3050 *) Add -X functionality back. This indicates to all MPMs and any other
3051 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
3053 *) Some initial support for the cygwin platform [prefork only].
3054 This is not to be confused with support for the WinNT/Win32
3055 platform, which is the recommended configuration for native
3056 Win32 users. The cygwin platform support is recommended for
3057 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
3059 *) Changed syntax of Set{Input|Output}Filter. The list of filters
3060 must be semicolon delimited (if more than one filter is given.)
3061 The Set{Input|Output}Filter directive now overrides a parent
3062 container's directive (e.g. SetInputFilter in <Directory /web/foo>
3063 will override any SetInputFilter directive in <Directory /web>.)
3064 This new syntax is more consistent with Add{Input|Output}Filter
3065 directives defined in mod_mime. Also cures a bug in prior releases
3066 where the Set{Input|Output}Filter directive would corrupt the
3067 global configuration if the multiple directives were nested.
3070 *) Cured what's ailed mime for quite some time. If an AddSomething
3071 was given in the configuration (Language, Charset, Handler or
3072 Encoding) Apache would set the content type as given by AddType,
3073 but refused to check the mime.types file if AddType wasn't given
3074 for that specific extension. Setting the AddHandler for .html
3075 without setting the AddType text/html html would cause Apache to
3076 use the default content type. [William Rowe]
3078 *) Added some bulletproofing to memory allocation in the LDAP cache
3079 code. [Graham Leggett]
3081 Changes with Apache 2.0.25
3083 *) Move the installed /manual directory out of the /htdocs/ tree, so
3084 that it can be kept more independently from the remaining document
3085 root. The "Alias /manual ..." already allowed for easy projection
3086 into existing private document trees. [Martin Kraemer]
3088 *) Add specified user attributes to the environment when using
3089 mod_auth_ldap. This allows you to use mod_include to embed specified
3090 user attributes in a page like so:
3091 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
3094 *) Fix a performance problem with the worker MPM. We now create
3095 transaction pools once, and re-use them for each connection.
3096 [Aaron Bannert <aaron@clove.org>]
3098 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
3099 of a 'handler' or 'filter', so that any filename extension that does
3100 not contribute to the negotiated metadata can't be served without
3101 an explicit request. E.g., if the .Z extension is associated with
3102 an unzip filter, the user request somefile.Z.html, mod_negotiation
3103 won't serve it. It can serve somefile.Z.html when somefile.Z is
3104 requested, since the .Z extension is explictly requested, if the
3105 .html extension is associated with ContentType text/html.
3108 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
3109 and corresponding AddOutputFilter syntax, to insert one or more
3110 filters by mod_mime filename extension processing.
3113 *) Fix a growing connection pool in core_output_filter() for
3114 keepalive requests. [Jeff Trawick]
3116 *) Moved split_and_pass_pretag_buckets back to being a
3117 macro at Ryans's request. Removed the return from it
3118 by setting and returning a return code instead. Updated
3119 the code to check the return code from the macro and
3120 do the right thing. [Paul J. Reder]
3122 *) Fix a segfault when a numeric value was received for Host:.
3125 *) Add a function ap_remove_input_filter. This is to match
3126 up with ap_remove_output_filter. [Ryan Bloom]
3128 *) Clean up location_walk, so that this step performs a minimum
3129 amount of redundant effort (it must be run twice, but it will no
3130 longer reparse all <Location > blocks when the request uri
3131 hadn't changed.) [William Rowe]
3133 *) Eliminate proxy: (and all other 'special') processing from the
3134 ap_directory_walk() phase. Modules that want to use special
3135 walk logic should refer to the mod_proxy map_to_location example,
3136 with it's proxy_walk and proxysection implementation. This makes
3137 either directory_walk flavor much more legible, since that phase
3138 only runs against real <Directory > blocks.
3141 *) SECURITY: Fix a security problem in mod_include which would allow
3142 an SSI document to be passed to the client unparsed.
3143 [Cliff Woolley, Brian Pane]
3145 *) Introduce the map_to_storage hook, which allows modules to bypass
3146 the directory_walk and file_walk for non-file requests. TRACE
3147 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
3148 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
3151 *) Add the ability for mod_include to add the INCLUDES filter
3152 if the file is configured for the server-parsed handler.
3153 This makes the configuration for .shtml files much easier
3154 to understand, and allows mod_include to honor Apache 1.3
3155 config files. Based on Doug MacEachern's patch to PHP
3156 to do the same thing. [Ryan Bloom]
3158 *) force OpenSSL to ignore process local-caching and to always
3159 get/set/delete sessions using mod_ssl's callbacks
3160 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
3161 Geoff Thorpe <geoff@geoffthorpe.net>]
3163 *) Make the worker MPM shutdown and restart cleanly. This also
3164 cleans up some race conditions, and gets the worker using
3165 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
3167 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
3169 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
3171 *) Fix for mod_include. Ryan's patch to check error
3172 codes put a return in the wrong place. Also, the
3173 include handler return code wasn't being checked.
3174 I don't like macros with returns, so I converted
3175 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
3176 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3178 *) fix segv in mod_mime if no AddTypes are configured
3179 [John Sterling <sterling@covalent.net>]
3181 *) Enable ssl client authentication at SSL_accept time
3182 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
3184 *) Fix a segfault in mod_include when the original request has no
3185 associated filename (e.g., we're filtering the error document for
3186 a bad URI). [Jeff Trawick]
3188 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
3190 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
3191 of httpd is started and shuts down due to socket conflict. Moving the
3192 call to ap_log_pid solves the problem.
3194 *) Changed the late-1.3 log_config substitution %c to %X, to log the
3195 status of the closed connection, as it conflicts with the far more
3196 common, historical ssl logging directive %...{var}c. [William Rowe]
3198 *) Added the common error/ tree to the build/install targets
3199 (similar to the common icons/ tree) for the multi-language error
3200 messages that Lars committed earlier. [William Rowe]
3202 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
3204 *) Added a default commented-out mod_ldap and mod_auth_ldap
3205 configuration to httpd-std.conf and httpd-win.conf
3208 *) Added documentation for mod_ldap and mod_auth_ldap.
3211 *) Enabled negative caching on attribute comparisons in the LDAP cache.
3212 Fixed a problem where the default cache TTL was set in milliseconds
3213 not microseconds causing the cache to time out almost immediately.
3216 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
3217 module code to follow APR. [Graham Leggett]
3219 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
3220 cleaned up when the connection pool pool is cleaned up.
3223 *) Fix a minor issue with Jeff Trawick's mod_include
3224 patch. Without this patch, the code will just allocate
3225 more bytes in get_combined_directive than are needed.
3228 *) Added the LDAP authentication module mod_auth_ldap.
3229 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
3231 *) Added the LDAP cache and connection pooling module mod_ldap.
3232 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
3234 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
3235 by allowing a module to disable itself if its prerequisites are not
3236 met. [Justin Erenkrantz]
3238 Changes with Apache 2.0.24
3240 *) Fix a couple of issues in mod_include when the tag appeared at
3241 offsets near 8192 in the file being parsed. [Jeff Trawick]
3243 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
3244 reached. [Jeff Trawick]
3246 *) Numerous improvements to the Win32 build system. Introduced command line
3247 builds without requiring .mak files for MSVC 6.0 and later versions.
3248 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
3251 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
3252 reporting of uninstalled services and other error conditions, and changed the
3253 default service name to Apache2. [William Rowe]
3255 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
3256 compatibility with existing Apache 1.3 Win32 Apache management utilites.
3257 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
3259 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
3260 [William Rowe, Greg Ames]
3262 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
3263 and RemoveCharset directives. [William Rowe]
3265 *) The Unix MPMs other than perchild now allow child server
3266 processes to use the accept mutex when starting as root and
3267 using SysV sems for the accept mutex. Previously, this
3268 combination would lead to fatal errors in the child server
3269 processes. perchild can't use SysV sems because of security
3270 issues. [Jeff Trawick, Greg Ames]
3272 *) Added Win32 revision stamp resources to all http binaries
3273 (including modules/ and support/ tools.) PR7322 [William Rowe]
3275 *) Fix ap_rvprintf to support more than 4K of data at one time.
3276 [Cody Sherr <csherr@covalent.net>]
3278 *) We have always used the obsolete/deprecated Netscape syntax
3279 for our tracking cookies; now the CookieStyle directive
3280 allows the Webmaster to choose the Netscape, RFC2109, or
3281 RFC2965 format. The new CookieDomain directive allows the
3282 setting of the cookie's Domain= attribute, too. PR #s 5006,
3283 5023, 5920, 6140 [Ken Coar]
3285 *) Tweak server/Makefile so that the rules for generating exports.c
3286 are compatible with make utilities which don't expand wildcards
3287 in a dependency list (e.g., OS/390 make, certain levels of GNU
3288 make). [Jeff Trawick]
3290 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
3292 *) Begin to sanitize the MPM configuration directives. Now, all
3293 MPMs use the same functions for all common MPM directives. This
3294 should make it easier to catch all bugs in these directives once.
3295 [Cody Sherr <csherr@covalent.net>]
3297 *) Close a major resource leak. Every time we had issued a
3298 graceful restart, we leaked a socket descriptor.
3301 *) Fix a problem with the new method code. We need to cast
3302 the 1 to an apr_int64_t or it will be treated as a 32-bit
3303 integer, and it will wrap after being shifted 32 times.
3304 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
3306 *) Fix a bug in mod_expires. Previous to this patch, if you
3307 told mod_expires to add 604800 seconds to the last-modified
3308 time, it actually added 604800 usec's to the last-modified time,
3309 so that when looking at the response it looked like nothing
3310 had been done. The root of the problem was that we always compute
3311 time in usec's, but we ask users to input sec's. This means we
3312 need to convert to usec's before using those values.
3315 *) The worker MPM now handles shutdown and restart requests. It
3316 definitely isn't perfect, but we do stop the servers correctly.
3317 The biggest problem right now is that SIGHUP causes the server to
3318 just die. [Ryan Bloom]
3320 Changes with Apache 2.0.23
3322 *) Use the prefork MPM by default on Unix. [various]
3324 *) Added a systray icon monitor application for Win32.
3325 [Mladen Turk <mturk@mappingsoft.com>]
3327 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3328 messages written to the rewrite log.
3329 [Richard Labennett <rlabenn@us.ibm.com>]
3331 *) All mod_autoindex query parsing is now quietly quashed with the
3332 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3333 still drops the column sort <a href>'s for the column headers, but
3334 IgnoreClient is required to ignore these Query options entirely.
3337 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3338 to allow the client to select plain, FancyIndexing or HTMLTable
3339 formatting, V=[0|1] to inhibit or enable version sorting, and
3340 P=pattern to return only specific files. The old Query Arguments
3341 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3342 as before), and O=A|D for ordering ascending or descending.
3345 *) Fixed an error in mod_include's directive parsing routines which
3346 caused #if, #elif, and #else expressions containing backslashes
3347 to be improperly evaluated. [Cliff Woolley]
3349 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3350 drop the icon column, SuppressRules to drop the <hr> elements,
3351 and HTMLTable to create rudimentary HTML table listings (implies
3352 FancyIndexing). [William Rowe]
3354 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3355 from Apache 1.3.15. This is needed for two reasons, first, given
3356 multiple machines within a server farm, ETags and Last-Modified
3357 stamps won't correspond from machine to machine, and second, many
3358 Unixes don't capture changes to the date or time stamp of existing
3359 files, since these don't modify the dirent itself. [William Rowe]
3361 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3362 and DirectoryWidth options from Apache 1.3.10.
3363 [William Rowe, Ken Coar]
3365 *) Eliminated FancyIndexing directive, deprecated early in Apache
3366 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3368 *) mod_autoindex now excludes any file names that would result in
3369 an error, other than a success or redirect. Also optimized
3370 the parent directory, always included except in the URI '/'.
3373 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3374 negotiated index pages, and prevent the server from defaulting
3375 to an autoindex of the directory. mod_negotiation will now die
3376 with a 500 Internal Error if it could match some filenames
3377 (e.g. for mod_dir) but none can be served. mod_negotation now
3378 refuses to serve any file with an extention that mod_mime doesn't
3379 recognize, and wasn't part of the request. [William Rowe]
3381 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3382 extension. This is already handled by multiviews, if the admin
3383 wishes to AddHandler .exe or define a content type handler and
3384 associate .exe files with that content type. Multiviews must be
3385 enabled to allow these to be served. [William Rowe]
3387 *) Speed up the server's response to a spike in incoming workload
3388 or restarts by assigning empty scoreboard slots to new processes
3389 when they are available. [Greg Ames]
3391 *) Add a handler to mod_includes.c. This handler is designed to
3392 implement the XbitHack directive. This can't be done with a
3393 fixup, because we need to check the content-type, which is
3394 only available in the handler phase. [Ryan Bloom]
3396 *) Make the includes filter check return codes from filters lower in
3397 the filter chain. If a lower level filter returns an error, then
3398 the request needs to stop immediately. This allows mod_include to
3399 stop parsing data once a lower filter recognizes an error.
3402 *) Add the ability to extend the methods that Apache understands
3403 and have those methods <limit>able in the httpd.conf. It uses
3404 the same bit mask/shifted offset as the original HTTP methods
3405 such as M_GET or M_POST, but expands the total bits from an int to
3406 an ap_int64_t to handle more bits for new request methods than
3407 an int provides. [Cody Sherr <csherr@covalent.net>]
3409 *) Fix broken mod_mime behavior in merging its arguments. Possible
3410 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
3412 *) Solve many mod_ssl porting issues (too many to detail) with
3413 help from the whole team, but most notably [Ralf S. Engelschall,
3414 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
3415 Doug MacEachern, William Rowe, Cliff Woolley]
3417 *) More stall fixes for the threaded & worker mpm's.
3418 Make mod_status output more accurate. Don't
3419 count workers in processes which aren't actively
3420 serving requests. [Greg Ames]
3422 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
3424 *) Add a single listener/multiple worker MPM. This MPM is
3425 definately not fully correct, but it allows us to solve many
3426 of the problems that exist in the threaded MPM. This is a
3427 modified version of the threaded MPM. [Ryan Bloom]
3429 *) Improve content generation throughout Apache, providing closer
3430 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
3431 Transitional specifications. [William Rowe]
3433 Changes with Apache 2.0.22
3435 *) Fix a problem where the threaded MPM stalls after restarts or
3436 segfaults. Also prevent multiple active processes from using
3437 the same scoreboard slot. [Greg Ames]
3439 *) Apache/Win32 now fills in the service description with Apache's
3440 server version string, including loaded and advertised modules.
3443 *) Improved support for the Win32 build, to recover gracefully from
3444 missing apr or apr-util directories or the awk interpreter,
3445 create the proper cgi-bin examples, including a test-cgi.bat, and
3446 fix the perl shebang line for printenv.pl, when installing from
3447 the build environment. [William Rowe]
3449 *) Fix a segfault in threaded.c caused by passing uninitialized
3450 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
3452 *) Use new APR number conversion functions to reduce CPU consumption
3453 when setting the content length, and in mod_log_config.
3456 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
3457 where HEAD response headers were being repeated twice for
3458 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
3459 problem in the http_header filter was exposed by the recent rewrite
3460 of the content_length filter. [Taketo Kabe, Bill Stoddard]
3462 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
3463 restarts. A garbage pointer to a vhost's server_rec from the
3464 previous generation was being left around under certain
3465 conditions. [Greg Ames]
3467 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
3468 used to appear as '(none', without the closing paren.
3469 [Günter Knauf <eflash@gmx.net>]
3471 *) Improve the exports generating awk script. In the past, we had
3472 work around problems in the awk script by avoiding some #if and
3473 #ifdefs. This has bitten us many times in generating the exports.c
3474 file. This improvement allows corrects the header file parsing.
3475 [Sander Striker <striker@apache.org>]
3477 Changes with Apache 2.0.21
3479 *) Resolve the Win32 htpasswd bug, where a file that existed would be
3480 overwritten, regardless of the -c flag.
3481 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
3483 *) Introduce connection sub-pools into ab. Truncating the lifetime
3484 of these allocations means that ab no longer perpetually grows
3485 its working set, running out of memory on large request attempts.
3488 *) Make scoreboard creation a hook. This allows management
3489 modules to have access to the scoreboard at the time that it is
3490 created, and at every restart request.
3491 [Cody Sherr <csherr@covalent.net>]
3493 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
3494 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
3495 daemon index actually used in the scoreboard. I also
3496 updated the pertinent calls. [Paul J. Reder]
3498 *) Win32: Prevent listening sockets from being inherited by
3499 the Apache child process, CGI scripts, rotatelog process
3500 etc. If the Apache child process segfaults, any processes
3501 that the child started are not reaped. Prior to this fix,
3502 these processes inherited the listening sockets which sometimes
3503 prevented the restarted Apache child process from accepting
3504 connections (ie, the server would hang).
3507 *) Provide vhost and request strings when ExtendedStatus is on.
3510 *) Fix some issues with the pod and prefork: check the pod *after*
3511 processing a connection so that a server processing a time-
3512 consuming request bails out as soon as practical; when the
3513 parent process wakes up a server process via connect(), use an
3514 APR timeout on the connect() so that we don't hang for a long
3515 time if there aren't server processes around to do accept().
3516 [Jeff Trawick, Greg Ames]
3518 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
3519 spends a lot of time in apr_table_get calls. Using the default
3520 httpd.conf, the tables for languages and charsets are somewhat
3521 large, so the time spent scanning them on each request is
3522 significant. Replacing the tables with hash tables provides
3523 a nice speedup. [Brian Pane <bpane@pacbell.net>]
3525 *) Add two functions to allow modules to access random parts of the
3526 scoreboard. This allows modules compiled for one MPM to access the
3527 scoreboard, even if it the server was compiled for another MPM.
3528 [Harrie Hazewinkel <harrie@covalent.net>]
3530 Changes with Apache 2.0.20
3532 *) Fix problem in content-length filter where the filter would
3533 buffer all the output from a CGI before sending any bytes
3534 down the filter stack to the network. This problem would cause
3535 significant memory consumption if the CGIs generated
3536 lots of bytes. [Bill Stoddard]
3538 *) Get non-blocking CGI pipe reads working with the bucket brigades.
3541 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
3544 *) Fix a bug in the threaded MPM that would cause it to kill off all
3545 workers immediately after starting if the number of workers started
3546 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
3548 Changes with Apache 2.0.19
3550 *) Fix problem with threaded MPM. The problem was that if each child
3551 process was busy serving a single long-lived request and the server
3552 was sent a graceful restart signal, the server would stop serving
3553 requests. This would happen because each child process would wait to
3554 die until the last thread was done, and the parent wouldn't spawn any
3555 new children until a process died. Now, the parent looks at the fact
3556 that the children are dying gracefully, and starts new children.
3557 Those new children only start enough threads to compliment the number
3558 of threads in the other child process that shares the same spot in
3559 the scoreboard. In this way, we make sure to never go over
3560 MaxClients. [Ryan Bloom]
3562 *) modified mod_negotiation and mod_autoindex to speed up by almost a
3563 factor of two on apr_dir_read()-enhanced platforms, such as Win32
3564 and OS2, by calling ap_sub_request_lookup_dirent() with the results
3565 already provided by apr_dir_read(). [William Rowe]
3567 *) mod_file_cache is now more robust to filtering and serves requests
3568 slightly more efficiently. [Cliff Woolley]
3570 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
3571 Module was calling ap_rwrite() followed by ap_rflush() but the
3572 served content was not being displayed in the browser. Inspection
3573 of the output stream revealed that the first data chunk was
3574 missing the trailing CRLF required by the RFC. [Bill Stoddard]
3576 *) apxs no longer generates ap_send_http_header() in the example handler
3578 *) Fix an ab problem which could cause a divide-by-zero exception
3579 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
3580 [Ian Holsman <ianh@cnet.com>]
3582 *) Solve case-insensitive platforms' confusion about negotiated
3583 filenames, allowing files of differnt case to match in choosing
3584 the document to serve. [William Rowe]
3586 *) Fix brokenness when ThreadsPerChild is higher than the built-in
3587 limit. We left ap_threads_per_child at the higher value which
3588 led to segfaults when doing certain scoreboard operations.
3591 *) Fix seg faults and/or missing output from mod_include. The
3592 default_handler was using the subrequest pool for files and
3593 MMAPs, even though the associated APR structures typically
3594 live longer than the subrequest. [Greg Ames]
3596 *) Extend mod_setenvif to support specifying regular expressions
3597 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
3598 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
3599 will cause HAVE_TS to be set if any of the request headers begins
3600 with "TS" and has a value that begins with any character in the
3601 set [a-z]. [Bill Stoddard]
3603 *) httpd children now re-bind themselves to a random CPU on
3604 multiprocessor systems on AIX via bindprocessor() in 2.0.
3605 [Victor J. Orlikowski]
3607 *) Fix htdigest. It would go into a loop in getline when adding
3608 a second user. [Bill Stoddard]
3610 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
3612 *) Automatically generate httpd.exp for AIX.
3613 DSOs now work again on AIX in 2.0
3614 [Victor J. Orlikowski]
3616 *) Add a new request hook, error_log. This phase allows modules
3617 to act on the error log string _after_ it has been written
3618 to the error log. The goal for this hook is to allow monitoring
3619 modules to send the error string to the monitoring agent.
3622 *) Modify mod_echo to make it use filters for input and output.
3623 [Ryan Morgan <rmorgan@covalent.net>]
3625 *) Extend mod_headers to support conditional driven Header
3626 add, append and set. Use SetEnvIf to set an envar and conditionally
3627 add/append/set headers based on this envar thusly:
3629 SetEnvIf TSMyHeader value HAVE_TSMyHeader
3630 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
3632 If the request contains header "TSMyHeader: value" then header
3633 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
3636 *) Extend mod_headers to support using format specifiers on Header
3637 add, append and set header values. Two format specifiers are supported:
3639 %t - reports, in UTC microseconds since the epoch, when the
3640 request was received.
3642 %D - reports the time, in microseconds, between when the request was
3643 received and the response sent.
3646 Header add MyHeader "This request served in %D microseconds. %t"
3648 results in a header being added to the response that looks like this:
3650 MyHeader: This request served in D=5438 microseconds. t=991424704447256
3654 *) Fix reset_filter(). We need to be careful how we remove filters.
3655 If we set r->output_filters to NULL, we also have to reset the
3656 connection's filters. [John Sterling]
3658 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
3660 *) Add a check to ap_die() to make sure the filter stack is sane and
3661 contains the correct basic filters when an error occurs. This fixes
3662 a problem where headers are not being sent on error. [John Sterling]
3664 *) New Header directive 'echo' option. "Header echo regex" will
3665 cause any headers received on the request that match regex to be
3666 echoed to (included in) the response headers.
3669 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
3670 This prevented the inclusion of apr_compat.h. PR #7773
3671 [Oleg Broytmann <phd@phd.pp.ru>]
3673 *) Moved util_uri to the apr-util library. This required a bunch of
3674 apr_name changes for the uri utility functions. [Justin Erenkrantz]
3676 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
3677 insert_filter phase so that other filters are not bypassed by default.
3680 *) Reimplement mod_headers as an output filter. mod_headers can now
3681 add custom headers to inbound requests using the RequestHeader directive
3682 and to responses using the same old Header directive. [Graham Leggett]
3684 Changes with Apache 2.0.18
3686 *) Fix command-line processing so that if a bad argument is specified
3687 Apache will exit. [Jeff Trawick]
3689 *) Change the make targets and rules to be consistent in all of the
3690 Apache-owned source trees. [Roy Fielding]
3692 *) Fix processing of the TRACE method. Previously we passed bogus
3693 parms to form_header_field() and it overlaid some vhost structures,
3694 resulting in a segfault in check_hostalias().
3695 [Greg Ames, Jeff Trawick]
3697 *) Win32: Add support for reliable piped logs. If the logging process
3698 goes down, Apache will automatically restart it. This function has
3699 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
3702 *) Do not start piped log processes during the config file
3703 preflight. This change also circumvents a problem on
3704 Windows where the rotatelog processes created during preflight
3705 was not getting cleaned up properly.
3708 *) add "Request Phase Participation" info to mod_info
3711 *) Make first phase changes to the scoreboard data structures in
3712 preparation for the rewriting of the scoreboard per my posted
3713 design notes. [Paul J. Reder]
3715 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
3716 and apr-util, allow it to be overridden by the configure command-line
3717 (default="--silent") and introduce LT_LDFLAGS to replace what we were
3718 formerly abusing as LTFLAGS. [Roy Fielding]
3720 *) Clean up the reporting of incorrect closing container tags.
3721 [Barrie Slaymaker <barries@slaysys.com>]
3723 *) Simplify the configure process by moving all libtool stuff to APR
3724 and moving hints.m4 inline. [Roy Fielding]
3726 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
3727 of functions used by mod_proxy for export in the DLL
3728 [Ian Holsman <IanH@cnet.com>]
3730 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
3731 request body from its stdin but no reqest body is being written to
3732 the cgi. [Jeff Trawick]
3734 *) mod_log_config: %c connection status incorrectly logged
3735 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
3738 *) Get mod_cern_meta working under Windows
3741 *) Create Files, and thus MMAPs, out of the request pool, not the
3742 connection pool. This solves a small resource leak that had us
3743 not closing files until a connection was closed. In order to do
3744 this, at the end of the core_output_filter, we loop through the
3745 brigade and convert any data we have into a single HEAP bucket
3746 that we know will survive clearing the request_rec.
3747 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
3750 *) Completely revamp configure so that it preserves the standard make
3751 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
3752 the configure additions to EXTRA_* variables. Also, allow the user
3753 to specify NOTEST_* values for all of the above, which eliminates the
3754 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
3755 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
3756 avoid pointless duplications. Fix the order in which flags are given
3757 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
3758 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
3759 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
3760 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
3762 *) Get mod_tls to compile/work better on Windows. PR #7612
3763 [Bernhard Schrenk <b.schrenk@improx.com>]
3765 *) Fix shutdown/restart hangs in the threaded MPM.
3766 [Jeff Trawick, Greg Ames, Ryan Bloom]
3768 *) Removed the keptalive boolean from conn_rec because it is now only
3769 used by a single routine and can be replaced by a local variable.
3770 [Greg Stein, Ryan Bloom, Roy Fielding]
3772 *) Patch prefork to put enough of the signal processing back in so that
3773 signals are all handled properly now. The previous patch fixed the
3774 deadlock race condition, but broke the user directed signal handling.
3775 This fixes it to work the way it did before my previous prefork patch
3776 (primarily, SIGTERM is now working).
3778 *) Change how input filters decide how much data is returned to the
3779 higher filter. We used to use a field in the conn_rec, with this
3780 change, we use an argument to ap_get_brigade to determine how much
3781 data is retrieved. [Ryan Bloom]
3783 *) Fix seg fault at start-up introduced by Ryan's change to enable
3784 modules to specify their own logging tags. mod_log_config
3785 registers an optional function, ap_register_log_handler().
3786 ap_register_log_handler() was being called by http_core before
3787 the directive hash table was created. This patch creates the
3788 directive hash table before ap_register_log_handler() is
3789 registered as an optional function.
3790 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
3792 *) Add ap_set_int_slot() function
3793 [John K. Sterling <sterling@covalent.net>]
3795 *) Under certain circumstances, Apache did not supply the
3796 right response headers when requiring authentication.
3797 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
3798 (This is a port of the change that went into Apache 1.3.19.)
3800 *) Allow modules to specify their own logging tags. This basically
3801 allows a module to tell mod_log_config that when %x is encountered
3802 a specific function should be called. Currently, x can be any single
3803 character. It may be more useful to make this a string at some point.
3806 Changes with Apache 2.0.17
3808 *) If a higher-level filter handles the the byterange aspects of a
3809 request, then the byterange filter should not try to redo the
3810 work. The most common case of this happening, is a byterange
3811 request going through the proxy, and the origin server handles
3812 the byterange request. The proxy should ignore it.
3813 [Graham Leggett <minfrin@sharp.fm>]
3815 *) Changed the threaded mpm to have child_main join to each of the
3816 worker threads to make sure the kids are all gone before child_main
3817 exits after a signal (cleanup from perform_idle_server_maintenance).
3818 This is an extension of Ryans recent commit to make the child_main
3821 *) Add more options to the ap_mpm_query function. This also allows MPMs to
3822 report if their threads are dynamic or static. Finally, this also
3823 implements a new API, ap_show_mpm, which returns the MPM that was
3824 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
3826 *) Do not install the binaries from the support directory twice.
3827 [jun-ichiro hagino <itojun@iijlab.net>]
3829 *) The ap_f* functions should flush data to the filter that is passed
3830 in, not the the filter after the one passed in.
3831 [Ryan Morgan <rmorgan@covalent.net>]
3833 *) Make ab work again by changing its native types to apr types and formats.
3834 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3836 *) Move the byterange filter and all of the supporting functions back
3837 to the HTTP module. The byterange filter turned out to be very
3838 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
3840 *) Make clean, distclean, and extraclean consistently according to the
3841 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3843 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
3844 This may have been causing problems stopping processes in the threaded
3847 *) Fix content-length in mod_negotiation to a long int representation.
3850 *) Remove BindAddress from the default config file.
3851 [giles@nemeton.com.au]
3853 *) Allow module authors to add a module to their Apache build using
3854 --with-module, without re-running buildconf. The syntax is:
3855 --with-module=module_type:/path/to/module.c
3856 The configure script will copy the module.c file to
3857 modules/module_type, and it will be added to the relevant Makefiles.
3858 currently, this only works for static modules. [Ryan Bloom]
3860 *) Changes required to make prefork clean up idle children properly.
3861 There was a window during which a starting worker deadlocks when
3862 an idle cleanup arrives before it completes init. Apache then keeps
3863 trying to cleanup the same deadlocked worker forever (until higher
3864 pids come along, but it still will never reduce below the deadlocked
3865 pid). Thus the number of children would not reduce to the correct
3866 idle level. [Paul J. Reder]
3868 Changes with Apache 2.0.16
3870 *) Change the default installation directory to /usr/local/apache2,
3871 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
3873 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
3876 *) Get MaxRequestsPerChild working with the Windows MPM.
3879 *) Make generic hooks to work, with mod_generic_hook_import/export
3880 experimental modules. [Ben Laurie, Will Rowe]
3882 *) Fix segfaults for configuration file syntax errors such as
3883 "<Directory>" followed by "</Directory" and
3884 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
3886 *) Cleanup the --enable-layout option of configure. This makes
3887 us use a consistent location for the config.layout file, and it
3888 makes configure more portable.
3889 [jun-ichiro hagino <itojun@iijlab.net>]
3891 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
3892 csv/gnuplot format, rudimentary ssl support and various other tweaks
3893 to make results more true to what is measured. The upshot of this it
3894 turns out that 'ab' has often underreported the true performance of
3895 apache. Often by a order of magnitude :-) See talk/paper of Sander
3896 Temme at April ApacheCon 2001 for details.
3897 [Dirk-Willem van Gulik]
3899 *) Clean up mod_cgid's temporary request pool. Besides fixing a
3900 storage leak this ensures that some unnecessary pipes are closed.
3903 *) Performance: Add quick_handler hook. This hook is called at the
3904 very beginning of the request processing before location_walk,
3905 translate_name, etc. This hook is useful for URI keyed content
3906 caches like Mike Abbott's Quick Shortcut Cache.
3909 *) top_module global variable renamed to ap_top_module [Perl]
3911 *) Move ap_set_last_modified to the core. This is a potentially
3912 controversial change, because this is kind of HTTP specific. However
3913 many protocols should be able to take advantage of this kind of
3914 information. I expect that headers will need one more layer of
3915 indirection for multi-protocol work, but this is a small step in
3916 the right direction. [Ryan Bloom]
3918 *) Enable mod_status by default. This matches what Apache 1.3 does.
3921 *) Add a ScriptSock directive to the default config file. This is
3922 only enabled when mod_cgid is used.
3923 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3925 Changes with Apache 2.0.15
3927 *) Untangled the buildconf script and eliminated the need for build's
3928 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
3929 libtool muck that is now under srclib/apr/build. [Roy Fielding]
3931 *) Win32: Don't accept more connections than we have worker threads
3935 *) Fix bug in the Unix threaded.c MPM that allowed child processes
3936 to fork() new child processes.
3939 *) SECURITY: Fix a major security problem with double-reverse lookup
3940 checking. Previously, a client connecting over IPv4 would not be
3941 matched properly when the server had an IPv6 listening socket.
3942 PR #7407 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
3944 *) Change the way the beos MPM handles polling to allow it to stop and
3945 restart. Problem was the sockets being polled were being reset by
3946 the select call, so once it had accepted a connection it was no
3947 longer listening on the UDP socket we use for shutdown instructions.
3948 APR needs to be altered, patch on it's way. [David Reid]
3950 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
3951 on error exit from ap_getline(). Some other code got upset because
3952 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
3954 *) Handle ap_discard_request_body() being called more than once.
3955 [Greg Ames, Jeff Trawick]
3957 *) Get rid of an inadvertent close of file descriptor 2 in
3958 mod_mime_magic. [Greg Ames, Jeff Trawick]
3960 *) Add a hook, create_request. This hook allows modules to modify
3961 a request while it is being created. This hook is called for all
3962 request_rec's, main request, sub request, and internal redirect.
3963 When this hook is called, the the r->main, r->prev, r->next
3964 pointers have been set, so modules can determine what kind of
3965 request this is. [Ryan Bloom]
3967 *) Cleanup the build process a bit more. The Apache configure
3968 script no longer creates its own helper scripts, it just
3970 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
3972 *) Stop the forced downgrade of the connection to HTTP/1.0 for
3973 proxy requests. [Graham Leggett]
3975 *) Avoid using sscanf to determine the HTTP protocol number in
3976 the common case because sscanf is a performance hog. From
3977 Mike Abbot's Accelerating Apache patch number 6.
3978 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
3980 *) SECURITY: Fix a security exposure in mod_access. Previously when
3981 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
3982 were not evaluated properly (PR #7407). Also, add the ability to
3983 specify IPv6 address strings with optional prefix length on Allow
3984 and Deny. [Jeff Trawick]
3986 *) Enhance rotatelogs so that a UTC offset can be specified, and
3987 the logfile name can be formatted using strftime(3). (Brought
3988 forward from 1.3.) [Ken Coar]
3990 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
3991 DuplicateHandle on an IOCompletionPort (a practice which
3992 MS "discourages"). The new model does not rely on associating
3993 the completion port with the listening sockets, thus the
3994 completion port can be completely managed within the child
3995 process. A dedicated thread accepts connections off the network,
3996 then calls PostQueuedCompletionStatus() to wake up worker
3997 threads blocked on the completion port.
4000 *) Bring forward the --suexec-umask option which allows the
4001 builder to preset the umask for suexec processes. [Ken Coar]
4003 *) Add a -V flag to suexec, which causes it to display the
4004 compile-time settings with which it was built. (Only
4005 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
4007 *) Mod_include should always unset the content-length if the file is
4008 going to be passed through send_parsed_content. There is no to
4009 determine if the content will change before actually scanning the
4010 entire content. It is far safer to just remove the C-L as long
4011 as we are scanning it. [Ryan Bloom]
4013 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
4014 request and not Proxy-Authenticate.
4015 [Graham Leggett <minfrin@sharp.fm>]
4017 Changes with Apache 2.0.14
4019 *) Fix content-length computation. We ONLY compute a content-length if
4020 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
4021 or we already have all the data. [Ryan Bloom]
4023 *) Report unbounded containers in the config file. Previously, a typo
4024 in the </container> directive could result in the rest of the config
4025 file being silently ignored, with undesired defaults used.
4028 *) Make the old_write filter use the ap_f* functions for the buffering.
4031 *) Move more code from the http module into the core server. This
4032 is core code, basically the default handler, the default input
4033 and output filters, and all of the core configuration directives.
4034 All of this code is required in order for the server to work, with or
4035 without HTTP. The server is closer to working without the HTTP
4036 module, although there is still more to do. [Ryan Bloom]
4038 *) Fix a number of SGI compile warnings throughout the server. Fix some
4039 bad parameters to apr_bucket_read(). Fix a bad statement in
4040 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
4041 consistently; we were mixing apr_time_t and time_t in invalid ways
4042 before. In load_file(), call apr_dso_error() instead of
4043 apr_strerror() so that we get a more specific string on some platforms.
4044 PR #6980 [Jeff Trawick]
4046 *) Allow modules to query the MPM about it's execution profile. This
4047 query API can and should be extended in the future, but for now,
4048 max_daemons, and threading or forking is a very good start.
4049 [Jon Travis <jtravis@covalent.net>]
4051 *) Modify mod_include to send blocks of data no larger than 9k.
4052 Without this, mod_include will wait until the whole file is parsed,
4053 or the first tag is found to send any data to the client.
4054 [Paul J. Reder <rederpj@raleigh.ibm.com>]
4056 *) Fix mod_info, so that <Directory> and <Location> directives are
4057 not displayed twice when displaying the current configuration.
4058 [Ryan Morgan <rmorgan@covalent.net>]
4060 *) Add config directives to override DEFAULT_ERROR_MSG and
4061 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
4062 [Dan Rench <drench@xnet.com>]
4064 *) Get mod_info building and loading on Win32. [William Rowe]
4066 *) Begin to move protocol independant functions out of mod_http. The goal
4067 is to have only functions that are HTTP specific in the http directory.
4070 Changes with Apache 2.0.13
4072 *) Don't assume that there will always be multiple calls to the byterange
4073 filter. It is possible that we will need to do byteranges with only
4074 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
4076 *) Move the error_bucket definition from the http module to the
4077 core server. Every protocol will need this ability, not just
4080 Changes with Apache 2.0.12
4082 *) Modify mod_file_cache to save pre-formatted strings for
4083 content-length and last-modified headers for performance.
4084 [Mike Abbot <mja@trudge.engr.sgi.com>]
4086 *) Namespace protect IOBUFSIZ since it is exposed in the API.
4087 [Jon Travis <jtravis@covalent.net>]
4089 *) Use "Basic" authentication instead of "basic" in ab, as the spec
4090 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
4092 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
4093 without ever filling it out. This fixes PR 7271.
4094 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
4095 Cliff Woolley <cliffwoolley@yahoo.com>]
4097 *) Add a couple of GCC attribute tags to printf style functions.
4098 [Jon Travis <jtravis@covalent.net>]
4100 *) Add the correct language tag for interoperation with the Taiwanese
4101 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
4103 *) Migrate the perchild MPM to use the new apr signal child, and
4104 APR thread functions. [Ryan Bloom]
4106 *) Close one copy of the CGI's stdout before creating the new process.
4107 The CGI will still have stdout, because we have already dup'ed it.
4108 This keeps Apache from waiting forever to send the results of a CGI
4109 process that has forked a long-lived child process.
4110 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
4112 *) Remove the rest of the pthreads functions from the threaded MPM.
4113 This requires the APR support for a signal thread that was just
4116 *) Make mod_dir use a fixup for sending a redirect to the browser.
4117 Before this, we were using a handler, which doesn't make much
4118 sense, because the handler wasn't generating any data, it would
4119 either return a redirect error code, or DECLINED. This fits the
4120 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
4122 *) Make the threaded MPM use APR threads instead of pthreads.
4125 *) Get mod_tls to the point where it actually appears to work in all cases.
4128 *) implement --enable-modules and --enable-mods-shared for "all" and
4129 "most". [Greg Stein]
4131 *) Move the threaded MPM to use APR locks instead of pthread locks.
4134 *) Rename mpmt_pthread to threaded. This is more in line with the
4135 fact that mpmt_pthread shouldn't be using pthreads directly, and
4136 it is a smaller name that doesn't tie into anything.
4139 *) Rename the module structures so that the exported symbol matches
4140 the file name, and it is easier to automate the installation
4141 process (generating LoadModule directives from the module filenames).
4144 *) Remove the coalesce filter. With the ap_f* functions, this filter
4145 is no longer needed. [Ryan Bloom]
4147 Changes with Apache 2.0.11
4149 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
4150 added feature of allowing a uid/gid per child process. If no
4151 uid/gid is specified, then Perchild behaves exactly like dexter.
4154 *) Get perchild building again. [Ryan Bloom]
4156 *) Don't disable threads just because we are using the prefork MPM.
4157 If somebody wants to compile without threads, they must now add
4158 --disable-threads to the configure command line. [Ryan Bloom]
4160 *) Begin to move the calls to update_child_status into common code, so
4161 that each individual MPM does not need to update the scoreboard itself.
4164 *) Allow mod_tls to compile under Unix boxes where openssl has been
4165 installed to the system include files.
4166 [Gomez Henri <new-httpd@slib.fr>]
4168 *) Cleanup the mod_tls configure process. This should remove any need
4169 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
4170 configure doesn't check that yet. [Ryan Bloom]
4172 *) Add a very early prototype of SSL support (in mod_tls.c). It is
4173 vital that you read modules/tls/README before attempting to build
4176 *) Fix a potential seg fault on all platforms. David Reid fixed this
4177 on BEOS, but the problem could happen anywhere, so we don't want
4178 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
4180 *) Add new LogFormat directive, %D, to log time it takes to serve a
4181 request in microseconds. [Bill Stoddard]
4183 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
4184 SetOutputFilter. This corresponds nicely with the other Set
4185 directives, which operate on containers while the Add* directives
4186 tend to work directly on extensions. [Ryan Bloom]
4188 *) Cleanup the header handling a bit. This uses the apr_brigade_*
4189 functions for the buffering so that we don't need to compute
4190 the length of the headers before we actually create the header
4191 buffer. [Ryan Bloom]
4193 *) Allow filters to buffer data using the ap_f* functions. These have
4194 become macros that resolve directly to apr_brigade_*.
4197 *) Get the Unix MPM's to do a graceful restart again. If we are going
4198 to register a cleanup with ap_cleanup_scoreboard, then we have to
4199 kill the cleanup with the same function, and that function can't be
4200 static. [Ryan Bloom]
4202 *) Install all required header files. Without these, it was not
4203 possible to compile some modules outside of the server.
4206 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
4207 forward from 1.3 to 2.0, we missed a single line, which broke regex
4208 aliases. [Ryan Bloom]
4210 *) We have a poor abstraction in the protocol. This is a temporary
4211 hack to fix the bug, but it will need to be fixed for real. If
4212 we find an error while sending out a custom error response, we back
4213 up to the first non-OK request and send the data. Then, when we send
4214 the EOS from finalize_request_protocol, we go to the last request,
4215 to ensure that we aren't sending an EOS to a request that has already
4216 received one. Because the data is sent on a different request than
4217 the EOS, the error text never gets sent down the filter stack. This
4218 fixes the problem by finding the last request, and sending the data
4219 with that request. [Ryan Bloom]
4221 *) Make the server status page show the correct restart time, and
4222 thus the proper uptime. [Ryan Bloom]
4224 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
4225 should reduce the amount of duplicate code that is required to
4226 create CGI processes.
4227 [Paul J. Reder <rederpj@raleigh.ibm.com>]
4229 *) ap_new_connection() closes the socket and returns NULL if a socket
4230 call fails. Usually this is due to a connection which has been
4231 reset. [Jeff Trawick]
4233 *) Move the Apache version information out of httpd.h and into release.h.
4234 This is in preparation for the first tag with the new tag and release
4235 system. [Ryan Bloom]
4237 *) Begin restructuring scoreboard code to enable adding back in
4238 the ability to use IPC other than shared memory.
4239 Get mod_status working on Windows again. [Bill Stoddard]
4241 *) Make mod_status work with 2.0. This will work for prefork,
4242 mpmt_pthread, and dexter. [Ryan Bloom]
4244 *) Correct a typo in httpd.conf.
4245 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
4247 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
4249 *) Get the correct IP address if ServerName isn't set and we can't
4250 find a fully-qualified domain name at startup.
4251 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
4253 *) Make mod_cgid work with SuExec. [Ryan Bloom]
4255 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
4256 'extra' stat's for user/group since they should never occur, and now
4257 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
4258 volumes. [William Rowe]
4260 *) Adopt apr features to simplify mod_includes. This changes the
4261 behavior of the USER_NAME variable, unknown uid's are now reported
4262 as USER_NAME="<unknown>" rather than the old user#000 result.
4263 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
4265 *) Adopt apr features for simplifing mod_userdir, and accept the new
4266 Win32/OS2 exceptions without hiccuping. [William Rowe]
4268 *) Replace configure --with-optim option by using and saving the
4269 environment variable OPTIM instead. This is needed because configure
4270 options do not support multiple flags separated by spaces.
4273 *) Fix some byterange handling. If we get a byte range that looks like
4274 "-999999" where that is past the end of the file, we should return
4275 a PARTIAL CONTENT status code, and return the whole file as one big
4276 byterange. This matches the 1.3 handling now. [Ryan Bloom]
4278 *) Make the error bucket a real meta-data bucket. This means that the
4279 bucket length is 0, and a read returns NULL data. If one of these
4280 buckets is passed down after the headers are sent, this data will
4281 just be ignored. [Greg Stein]
4283 *) The prefork MPM wasn't killing child processes correctly if a restart
4284 signal was received while the process was serving a request. The child
4285 process would become the equivalent of a second parent process. If
4286 we break out of the accept loop, then we need to do die after cleaning
4287 up after ourselves. [Ryan Bloom]
4289 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
4290 restarts. [Ryan Bloom]
4292 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
4293 the most optimal APR_FINFO_wanted bits. This spares Win32 from
4294 performing very expensive owner, group and permission lookups
4295 and allows the server to function until these apr_finfo_t fields
4296 are implemented under Win32. [William Rowe]
4298 *) Support for typedsafe optional functions - that is functions exported by
4299 optional modules, which, therefore, may or may not be present, depending
4300 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
4301 for sample code. [Ben Laurie]
4303 *) filters can now report an HTTP error to the server. This is done
4304 by sending a brigade where the first bucket is an error_bucket.
4305 This bucket is a simple bucket that stores an HTTP error and
4306 a string. Currently the string is not used, but it may be needed
4307 to output an error log. The http_header_filter will find this
4308 bucket, and output the error text, and then return
4309 AP_FILTER_ERROR, which informs the server that the error web page
4310 has already been sent. [Ryan Bloom]
4312 *) If we get an error, then we should remove all filters except for
4313 those critical to serving a web page. This fixes a bug, where
4314 error pages were going through the byterange filter, even though
4315 that made no sense. [Ryan Bloom]
4317 *) Relax the syntax checking of Host: headers in order to support
4318 iDNS. PR#6635 [Tony Finch]
4320 *) Cleanup the byterange filter to use the apr_brigade_partition
4321 and apr_bucket_copy functions. This removes a lot of very messy
4322 code, and hopefully makes this filter more stable.
4325 *) Remove AddModule and ClearModuleList directives. Both of these
4326 directives were used to ensure that modules could be enabled
4327 in the correct order. That requirement is now gone, because
4328 we use hooks to ensure that modules are in the correct order.
4331 *) When SuExec is specified, we need to add it to the list of
4332 targets to be built. If we don't, then any changes to the
4333 configuration won't affect SuExec, unless 'make suexec' is
4334 specifically run. [Ryan Bloom]
4336 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4337 the APR_XTHREAD argument to open a file for consumption by
4338 parallel threads on win32. [William Rowe]
4340 *) Correct a bug in determining when we follow symlinks. The code
4341 expected a stat -1 result, not an apr_status_t positive error.
4342 Also check if the APR_FINFO_USER fields are valid before we
4343 follow the link. [William Rowe]
4345 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4346 mpm_common.c. These functions are only valid on some platforms,
4347 so they should not be in the main-line code. [Ryan Bloom]
4349 *) Remove ap_chdir_file(). This function is not thread-safe,
4350 and nobody is currently using it. [Ryan Bloom]
4352 *) Do not try to run make depend if there are no .c files in the
4353 current directory, doing so makes `make depend` fail.
4356 *) Update highperformance.conf to work with either prefork or
4357 pthreads mpms. [Greg Ames]
4359 *) Stop checking to see if this is a pipelined request if we know
4360 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4361 This keeps us from making an extra read call when serving a 1.0
4362 request. [Ryan Bloom and Greg Stein]
4364 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4365 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4366 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4368 *) Fix the RFC number mentioned when complaining about a missing
4369 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
4371 *) Fix an endless loop in ab which occurred when ab was posting
4372 and the server dropped the connection unexpectedly.
4375 *) Fix a segfault while handling request bodies in ap_http_filter().
4376 This problem has been seen with mod_dav usage as well as with
4377 requests where the body was just being discarded. [Jeff Trawick]
4379 *) Some adjustment on the handling and automatic setting (via
4380 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4381 add the capability to specify flags (NOTEST_CFLAGS and
4382 NOTEST_LDFLAGS) which are used to compile Apache, but
4383 not used during the configuration process. Useful for
4384 flags like "-Werror". [Jim Jagielski]
4386 *) Stop using environment variables to force debug mode or
4387 no detach. We now use the -D command line argument to
4388 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4389 [Greg Stein, Ryan Bloom]
4391 *) Change handlers to use hooks. [Ben Laurie]
4393 *) Stop returning copies of filenames from both apr_file_t and
4394 apr_dir_t. We pstrdup the filenames that we store in the
4395 actual structures, so we don't need to pstrdup the strings again.
4398 *) mod_cgi: Fix some problems where the wrong error value was being
4399 traced. [Jeff Trawick]
4401 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
4404 *) Add generic hooks. [Ben Laurie]
4406 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
4408 *) Fix a segfault caused by mod_ext_filter when the external filter
4409 program does not exist. [Jeff Trawick]
4411 *) Fix an output truncation error when on an HTTP >= 1.0 request an
4412 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
4413 was served through mod_charset_lite (or anything else that would
4414 create a transient bucket in this size range). ap_bucket_make_heap()
4415 silently failed (fixed), transient_setaside() discovered it, but
4416 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
4418 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
4419 is that some browsers send extra lines at the end of POST requests, and
4420 we don't want to delay sending data back to the user just because the
4421 browser isn't well behaved. [Ryan Bloom]
4423 *) Get SuEXEC working again. We can't send absolute paths to suExec
4424 because it refuses to execute those programs. SuEXEC also wasn't
4425 always recognizing configuration changes made using the autoconf
4428 *) Allow the buildconf process to find the config.m4 files in the correct
4429 order. Basically, we can now name config.m4 files as config\d\d.m4,
4430 and we will sort them correctly when inserting them into the build
4431 process. [Ryan Bloom]
4433 *) Get mod_cgid to use apr calls for creating the actual CGI process.
4434 This also allows mod_cgid to use ap_os_create_priviledged_process,
4435 thus allowing for SuExec execution from mod_cgid. Currently, we do
4436 not support everything that standard SuExec supports, but at least
4437 it works minimally now. [Ryan Bloom]
4439 *) Allow SuExec to be configured from the ./configure command line.
4442 *) Update some of the docs in README and INSTALL to reflect some of
4443 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
4445 *) If we get EAGAIN returned from the call to apr_sendfile, then we
4446 need to call sendfile again. This gets us serving large files
4447 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
4449 *) Get the support programs building cleanly again.
4450 [Cliff Woolley <cliffwoolley@yahoo.com>]
4452 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
4453 current directory logic now backs up over bin/ to determine the
4454 server root from the Apache.exe path.
4456 *) Apache/Win32 now follows the standard conventions of mod_foo.so
4457 loadable modules, dynamic libs are all named libfoo.dll, and the
4458 makefile.win populates the include, lib and libexec directories.
4460 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
4461 Apache gets IPv6 listening sockets by default. Additionally, the
4462 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
4463 numeric address strings (e.g., "Listen [fe80::1]:8080").
4466 *) Modify the install directory layout. Modules are now installed in
4467 modules/. Shared libraries should be installed in libraries/, but
4468 we don't have any of those on Unix yet. All install directories
4469 are modifyable at configure time. [Ryan Bloom]
4471 *) Install all header files in the same directory on Unix. [Ryan Bloom]
4473 *) Get the functions in server/linked into the server, regardless of
4474 which modules linked into the server. This uses the same hack
4475 for Apache that we use for APR and apr-util to ensure all of the
4476 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
4477 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
4478 the scripts a bit easier.
4481 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
4482 on the query, and remove IPv4 dependencies. [Jeff Trawick]
4484 *) Get all of the auth modules to the point that they will install and
4485 be loadable into the server. Our new build/install mechanism expects
4486 that all modules will have a common name format. The auth modules
4487 didn't use that format, so we didn't install them properly.
4490 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
4491 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
4493 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
4495 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
4496 after the end of the response. [Ryan Bloom]
4498 *) Get byterange requests working with responses that do not have a
4499 content-length. Because of the way byterange requests work, we have to
4500 have all of the data before we can actually do the byterange, so we
4501 can compute the content-length in the byterange filter.
4504 *) Get exe CGI's working again on Windows.
4507 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
4508 they keep track of whether or not their post config hook has been
4509 called before. Instead of a static variable (which is replaced when
4510 the DSO is loaded a second time), use userdata in the process pool.
4513 Changes with Apache 2.0a9
4515 *) Win32 now requires perl to complete the final install step for users
4516 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
4517 and installs the conf, htdocs and htdocs/manual directories.
4520 *) Make mod_include use a hash table to associate directive tags with
4521 functions. This allows modules to implement their own SSI tags easily.
4522 The idea is simple enough, a module can insert it's own tag and function
4523 combination into a hash table provided by mod_include. While mod_include
4524 parses an SSI file, when it encounters a tag in the file, it does a
4525 hash lookup to find the function that implements that tag, and passes
4526 all of the relevant data to the function. That function is then
4527 responsible for processing the tag and handing the remaining data back
4528 to mod_include for further processing.
4529 [Paul J. Reder <rederpj@raleigh.ibm.com>]
4531 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
4532 fewer parameters: the local and remote socket addresses were removed
4533 from the parameter list because all required information is available
4534 via the APR socket. [Jeff Trawick]
4536 *) Distribution directory structure reorganized to reflect a
4537 normal source distribution with external install targets.
4540 *) The MPMs that need multiple segments of shared memory now create
4541 two apr_shmem_t variables, one for each shared memory allocation.
4542 the problem is that we can't determine how much memory will be required
4543 for shared memory allocations once we try to allocate more than one
4544 variable. The MM code automatically aligns the shared memory allocations,
4545 so we end up needing to pad the amount of shared memory we want based
4546 on how many variables will be allocated out of the shared memory segment.
4547 It is just easier to create a second apr_shmem_t variable, and two
4548 shmem memory blocks.
4551 *) Cleanup the export list a bit. This creates a single unified list of
4552 functions exported by APR. The export list is generated at configure
4553 time, and that list is then used to generate the exports.c file.
4554 Because of the way the export list is generated, we only export those
4555 functions that are valid on the platform we are building on.
4558 *) Enable logging the cookie with mod_log_config
4559 [Sander van Zoest <sander@covalent.net>]
4561 *) Fix a segfault in mod_info when it reaches the end of the configuration.
4564 *) Added lib/aputil/ as a placeholder for utility functions which are not
4565 specific to the Apache HTTP Server (but do not make sense with APR).
4566 The first utility is "apu_dbm": a set of functions to work with DBM
4567 files. This first version can be compiled for SDBM or GDBM databases.
4570 *) Complete re-write of mod_include. This makes mod_include a filter that
4571 uses buckets directly. This has now served the FAQ correctly.
4572 [Paul Reder <rederpj@raleigh.ibm.com>]
4574 *) Allow modules to specify the first filter in a sub_request when
4575 making the sub_request. This keeps modules from having to change the
4576 output_filter immediately after creating the sub-request, and therefore
4577 skip the sub_req_output_filter. [Ryan Bloom]
4579 *) Update ab to accept URLs with IPv6 literal address strings (in the
4580 format described in RFC 2732), and to build Host header fields in
4581 the same format. This allows IPv6 literal address strings to be
4582 used with ab. This support has been tested against Apache 1.3 with
4583 the KAME patch, but Apache 2.0 does not yet work with this format
4584 of the Host header field. [Jeff Trawick]
4586 *) Accomodate an out-of-space condition in the piped logs and the
4587 rotatelogs.c code, and no longer churn log processes for this
4588 condition. [Victor J. Orlikowski]
4590 *) Add support for partial writes with apr_sendfile() to core_output_filter.
4593 Changes with Apache 2.0a8
4595 *) Add a directive to mod_mime so that filters can be associated with
4599 *) Get multi-views working again. We were setting the path_info
4600 field incorrectly if we couldn't find the specified file.
4603 *) Fix 304 processing. The core should never try to send the headers
4604 down the filter stack. Always, just setup the table in the request
4605 record, and let the header filter convert it to data that is ready
4609 *) More fixes for the proxy. There are still bugs in the proxy code,
4610 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
4614 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
4617 *) APR: Add new apr_getopt_long function to handle long options.
4618 [B. W. Fitzpatrick <fitz@red-bean.com>]
4620 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
4621 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
4622 hostname resolution/address string parsing and building
4623 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
4624 of one of the apr_sockaddr_t structures for a socket. Change
4625 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
4627 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
4628 I have proxied pages with it, cleanup will commence soon.
4631 *) Make the proxy work with filters. This isn't perfect, because we
4632 aren't dealing with the headers properly. [Ryan Bloom]
4634 *) Do not send a content-length iff the C-L is 0 and this is a head
4635 request. [Ryan Bloom]
4637 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
4638 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
4640 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
4642 *) Get the default_handler to stop trying to deal with HEAD requests.
4643 The idea is to let the content-length filter compute the C-L before
4644 we try to send the data. If we can get the C-L correctly, then we
4645 should send it in the HEAD response.
4648 *) The Header filter can now determine if a body should be sent based
4649 on r->header_only. The general idea of this is that if we delay
4650 deciding to send the body, then we might be able to compute the
4651 content-length correctly, which will help caching proxies to cache
4652 our data better. Any handler that doesn't want to try to compute
4653 the content-length can just send an EOS bucket without data and
4654 everything will just work.
4657 *) Add the referer to the error log if one is available.
4658 [Markus Gyger <mgyger@itr.ch>]
4660 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
4661 change, the root of the configuration tree has been exposed to modules
4663 [Ryan Morgan <rmorgan@covalent.net>]
4665 *) Get the core_output_filter to use the bucket interface directly.
4666 This keeps us from calling the content-length filter multiple times
4667 for a simple static request.
4670 *) We are sending the content-type correctly now.
4671 [Ryan Bloom and Will Rowe]
4673 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
4674 a bogus bytes-sent value when the only thing being sent was trailers
4675 and writev() returned an error (or EAGAIN). [Jeff Trawick]
4677 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
4678 hints file to determine which platforms define
4679 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
4682 *) APR: add apr_get_home_directory() [Jeff Trawick]
4684 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
4686 *) Not all platforms have INADDR_NONE defined by default. Apache
4687 used to make this check and define INADDR_NONE if appropriate,
4688 but APR needs the check too, and I suspect other applications will
4689 as well. APR now defines APR_INADDR_NONE, which is always a valid
4690 value on all platforms.
4691 [Branko Èibej <brane@xbc.nu>]
4693 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
4694 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
4696 *) Relax the syntax checking of Host: headers in order to support
4697 iDNS. PR#6635 [Tony Finch]
4699 *) When reading from file buckets we convert to an MMAP if it makes
4700 sense. This also simplifies the default handler because the
4701 default handler no longer needs to try to create MMAPs.
4704 *) BUFF has been removed from the main server. The BUFF code will remain
4705 in the code until it has been purged from the proxy module as well.
4708 *) Byteranges have been completely re-written to be a filter. This
4709 has been tested, and I believe it is working correctly, but it could
4710 doesn't work for the Adobe Acrobat plug-in. The output almost matches
4711 the output from 1.3, the only difference being that 1.3 includes
4712 a content-length in the response, and this does not.
4715 *) APR read/write functions and bucket read functions now operate
4716 on unsigned integers, instead of signed ones. It doesn't make
4717 any sense to use signed ints, because we return the error codes,
4718 so if we have an error we should report 0 bytes read or written.
4721 *) Always compute the content length, whether it is sent or not.
4722 The reason for this, is that it allows us to correctly report
4723 the bytes_sent when logging the request. This also simplifies
4724 content-length filter a bit, and fixes the actual byte-reporing
4725 code in mod_log_config.c
4728 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
4729 it says, because it was only used by EOS and FLUSH buckets. Since
4730 neither of those are required at the end of a brigade, this was
4731 really signifying FLUSH_THE_DATA, but that can be determined better
4732 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
4733 buckets now return a length of 0, which is actually the amount of data
4734 read, so they make more sense.
4737 *) Allow the core_output_filter to save some data past the end of a
4738 request. If we get an EOS bucket, we only send the data if it
4739 makes sense to send it. This allows us to pipeline request
4740 responses. As a part of this, we also need to allocate mmap
4741 buckets out of the connection pool, not the request pool. This
4742 allows the mmap to outlive the request.
4745 *) Make blocking and non-blocking bucket reads work correctly for
4746 sockets and pipes. These are the only bucket types that should
4747 have non-blocking reads, because the other bucket types should
4748 ALWAYS be able to return something immediately.
4751 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
4752 server, but use Ctrl+Break to initiate a graceful restart
4753 instead of duplicating behavior. [John Sterling]
4755 *) Patch mod_autoindex to set the Last-Modified header based on
4756 the directory's mtime, and add the ETag header. [William Rowe]
4758 *) Merge the 1.3 patch to add support for logging query string in
4759 such a way that "%m %U%q %H" is the same as "%r".
4762 *) Port three log methods from mod_log_config 1.3 to 2.0:
4763 CLF compliant '-' byte count, method and protocol.
4766 *) Add a new LogFormat directive, %c, that will log connection
4767 status at the end of the response as follows:
4768 'X' - connection aborted before the response completed.
4769 '+' - connection may be kept-alive by the server.
4770 '-' - connection will be closed by the server.
4773 *) Expand APR for WinNT to fully accept and return utf-8 encoded
4774 Unicode file names and paths for Win32, and tag the Content-Type
4775 from mod_autoindex to reflect that charset if the the feature
4776 macro APR_HAS_UNICODE_FS is true. [William Rowe]
4778 *) Compute the content length (and add appropriate header field) for
4779 the response when no content length is available and we can't use
4780 chunked encoding. [Jeff Trawick]
4782 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
4783 so that content input filters get dechunked data when using
4784 the default handler. Also removed REQUEST_CHUNKED_PASS.
4787 *) Add mod_ext_filter as an experimental module. This module allows
4788 the administrator to use external programs as filters. Currently,
4789 only filtering of output is supported. [Jeff Trawick]
4791 *) Most Apache functions work on EBCDIC machines again, as protocol
4792 data is now translated (again). [Jeff Trawick]
4794 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
4795 the EBCDIC support. They are noops on ASCII machines, so this
4796 type of translation doesn't have to be surrounded by #ifdef
4797 CHARSET_EBCDIC. [Jeff Trawick]
4799 *) Fix mod_include. tag commands work again, and the server will
4800 send the FAQ again. This also allows mod_include to set aside
4801 buckets that include partial buckets.
4802 [Ryan Bloom and David Reid]
4804 *) Add suexec support back. [Manoj Kasichainula]
4806 *) Lingering close now uses the socket directly instead of using
4807 BUFF. This has been tested, but since all we can tell is that it
4808 doesn't fail, this needs to be really hacked on.
4811 *) Allow filters to modify headers and have those headers be sent to
4812 the client. The idea is that we have an http_header filter that
4813 actually sends the headers to the network. This removes the need
4814 for the BUFF to send headers.
4817 *) Charset translation: mod_charset_lite handles translation of
4818 request bodies. Get rid of the xlate version of ap_md5_digest()
4819 since we don't compute digests of filtered (e.g., translated)
4820 response bodies this way anymore. (Note that we don't do it at
4821 all at the present; somebody needs to write a filter to do so.)
4824 *) Input filters and ap_get_brigade() now have a input mode parameter
4825 (blocking, non-blocking, peek) instead of a length parameter.
4828 *) Update the mime.types file to the registered media types as
4829 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
4832 *) Namespace protect some macros declared in ap_config.h
4835 *) Support HTTP header line folding with input filtering.
4838 *) Mod_include works again. This should still be re-written, but at
4839 least now we can serve an SHTML page again.
4842 *) Begin to remove BUFF from the core. Currently, we keep a pointer
4843 to both the BUFF and the socket in the conn_rec. Functions that
4844 want to use the BUFF can, functions that want to use the socket,
4845 can. They point to the same place.
4848 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
4849 [Tomas "Ögren" <stric@ing.umu.se>]
4851 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
4852 associated pool goes away. (APR pipes on OS/2 were already had this
4853 logic.) This resolvs a fatal file descriptor leak with CGIs.
4856 *) The final line of the config file was not being read if there was
4857 no \n at the end of it. This was caused by apr_fgets returning
4858 APR_EOF even though we had read valid data. This is solved by
4859 making cfg_getline check the buff that was returned from apr_fgets.
4860 If apr_fgets return APR_EOF, but there was data in the buf, then we
4861 return the buf, otherwise we return NULL.
4864 *) Piped logs work again in the 2.0 series.
4867 *) Restore functionality broken by the mod_rewrite security fix:
4868 rewrite map lookup keys and default values are now expanded
4869 so that the lookup can depend on the requested URI etc.
4870 PR #6671 [Tony Finch]
4872 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
4873 security bug in some mass virtual hosting configurations
4874 that can allow a remote attacker to retrieve some files
4875 on the system that should be inaccessible. [Tony Finch]
4877 *) Add a pool bucket type. This bucket is used for data allocated out
4878 of a pool. If the pool is cleaned before the bucket is destroyed, then
4879 the data is converted to a heap bucket, allowing it to survive the
4883 *) Add a flush bucket. This allows modules to signal that the filters
4884 should all flush whatever data they currently have. There is no way
4885 to actually force them to do this, so if a filter ignores this bucket,
4886 that's life, but at least we can try with this.
4889 *) Add an output filter for sub-requests. This filter just strips the
4890 EOS bucket so that we don't confuse the main request's core output
4891 filter by sending multiple EOS buckets. This change also makes sub
4892 requests start to send EOS buckets when they are finished.
4895 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
4896 makes ap_bucket_destroy a return void, which is okay because it
4897 used to always return APR_SUCCESS, and nobody ever checked its
4898 return value anyway.
4899 [Cliff Woolley <cliffwoolley@yahoo.com>]
4901 *) Remove the index into the bucket-type table from the buckets
4902 structure. This has now been replaced with a pointer to the
4903 bucket_type. Also add some macros to test the bucket-type.
4906 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
4907 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
4908 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
4909 All _VAR_ flavors changes to _DATA to be absolutely clear.
4912 *) Add support for /, //, //servername and //server/sharename
4913 parsing of <Directory> blocks under Win32 and OS2.
4914 [Tim Costello, William Rowe, Brian Harvard]
4916 *) Remove the function pointers from the ap_bucket type. They have been
4917 replaced with a global table. Modules are allowed to register bucket
4918 types and use then use those buckets.
4921 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
4922 once we finish writing the request body to the cgi child process;
4923 otherwise, the client doesn't hit EOF on stdin. Small request bodies
4924 worked without this change (for reasons I don't understand), but large
4925 ones didn't. [Jeff Trawick]
4927 *) Remove file bucket specific information from the ap_bucket type.
4928 This has been moved to a file_bucket specific type that hangs off
4929 the data pointer in the ap_bucket type.
4932 *) Input filtering now has a third argument. This is the amount of data
4933 to read from lower filters. This argument can be -1, 0, or a positive
4934 number. -1 means give me all the data you have, I'll deal with it and
4935 let you know if I need more. 0 means give me one line and one line
4936 only. A positive number means I want no more than this much data.
4938 Currently, only 0 and a positive number are implemented. This allows
4939 us to remove the remaining field from the conn_rec structure, which
4943 *) Big cleanup of the input filtering. The goal is that http_filter
4944 understands two conditions, headers and body. It knows where it is
4945 based on c->remaining. If c->remaining is 0, then we are in headers,
4946 and http_filter returns a line at a time. If it is not 0, then we are
4947 in body, and http_filter returns raw data, but only up to c->remaining
4948 bytes. It can return less, but never more.
4949 [Greg Ames, Ryan Bloom, Jeff Trawick]
4951 *) mod_cgi: Write all of the request body to the child, not just what
4952 the kernel would accept on the first write. [Jeff Trawick]
4954 *) Back out the change that moved the brigade from the core_output_filters
4955 ctx to the conn_rec. Since all requests over a given connection
4956 go through the same core_output_filter, the ctx pointer has the
4960 *) Fix another bug in the send_the_file() read/write loop. A partial
4961 send by apr_send would cause unsent data in the read buffer to
4962 get clobbered. Complete making send_the_file handle partial
4963 writes to the network.
4966 *) Fix a couple of type fixes to allow compilation on AIX again
4967 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
4969 *) Fix bug in send_the_file() which causes offset to be ignored
4970 if there are no headers to send.
4973 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
4974 filter. Useful for supporting Windows 9* with a binary
4975 compiled on Windows NT.
4978 Changes with Apache 2.0a7
4980 *) Reimplement core_output_filter to buffer/save bucket brigades
4981 across multiple calls to the core_filter. The brigade will be
4982 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
4983 thresholds are hit or the EOS bucket is received.
4986 *) Create experimental filter (buffer_filter) that coalesces bytes
4987 into one large buffer before invoking the next filter in the
4988 chain. This filter is particularly useful with the current
4989 implementation of mod_autoindex when it inserted above the
4990 chunk_filter. mod_autoindex generates a lot of brigades that
4991 containing buckets holding just a few bytes each. The
4992 buffer_filter coalesces these buckets into a single large bucket.
4995 *) Add apr_sendfile() support into the core_output_filter.
4998 *) Add apr_sendv() support into the core_output_filter.
5001 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
5002 [Mike Abbott <mja@sgi.com>]
5004 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
5005 make much sense, because Apache uses buckets instead of BUFFs now.
5008 *) send_the_file now falls back to a read/write loop on platforms that
5009 do not have sendfile.
5010 [Ryan Bloom and Brian Havard]
5012 *) Install apachectl correctly, and substitute the proper values so
5013 that it works again. [Ryan Bloom]
5015 *) Better(??) handle platforms that lack sendfile().
5018 *) APR now has UUID generation/formatting/parsing support.
5021 *) Begin the http_filter. This is an input filter that understands
5022 the absolute basic amount required to parse an HTTP Request. The
5023 goal is to be able to split headers from request body before passing
5024 the data back to the other filters.
5027 *) Bring forward from 1.3.13 the config directory implementation
5030 *) install apxs if it is created
5033 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
5034 conversions. [William Rowe]
5036 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
5037 ap_add_output_filter(). [Jeff Trawick]
5039 *) Multiple build and configuration fixes
5042 -add datadir and localstatedir substitutions
5044 -fix logfilename misspelling
5045 -fix evaluation of installation dir variables and
5046 -replace $foobar by $(foobar) to be usefull in the makefile
5050 -add rules for cross-compiling in rules.mk. Okay, rule to check for
5051 $CC_FOR_BUILD is still missing
5052 -use CHECK_TOOL instead of CHECK_PROG for ranlib
5053 -add missing "AR=@AR@" to severaly Makefile.in's
5054 -cache result for "struct rlimit"
5055 -compile all helper programs with native and cross compiler
5056 and use the native version to generate header file
5057 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
5059 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
5061 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
5063 *) Fix a bug where a client which only sends \n to delimit header
5064 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
5065 message. Start working on ebcdic co-existance with input
5067 [William Rowe, Greg Ames]
5069 *) If mod_so is enabled in the server always create libexec, even
5070 if there are no modules installed in this directory. This is a
5071 requirement for APXS to work correctly.
5074 *) Connection oriented output filters are now stored in the
5075 conn_rec instead of the request_rec. This allows us to add the
5076 output filter in the pre-connection phase instead of the
5077 post_read_request phase, which keeps us from trying to write an
5078 error page before we have a filter to write to the network.
5079 [Ryan Bloom, Jeff Trawick, and Greg Ames]
5081 *) Cleaning up an mmap bucket no longer deletes the mmap. An
5082 mmap can be used across multiple buckets (default_handler with
5083 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
5084 the mmap itself can't be associated with the bucket.
5087 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
5090 *) Radical surgery to improve mod_isapi support under Win32.
5091 Includes a number of newer ServerSupportFunction calls, support
5092 for ReadClient (in order to retrieve POSTs greater than 48KB),
5093 and general bug fixes to more reliably load ISAPI .dll's and
5094 prevent leaking handle resources. Note: There are still
5095 discrepancies between IIS's and Apache's ServerVariables, and
5096 async calls are still not supported. Additional warnings are
5097 logged to facilitate debugging of unsupported ISAPI calls.
5100 *) Add input filtering to Apache. The basic idea for the input
5101 filters is the same as the ideas for output filters. The biggest
5102 difference is that instead of calling ap_pass_brigade, ap_get_brigade
5103 should be called, and the order of execution for the filter itself is
5104 different. When writing an output filter, a brigade is passed in,
5105 and filters operate directly on that brigade, when done, they call
5106 ap_pass_brigade. Input filters are the exact opposite. Because input
5107 is not a push operation, filters first call ap_get_brigade. When this
5108 function returns, the input filter will be left with a valid brigade.
5109 The input filter should then operate on the brigade, and return.
5112 *) Fix building on BSD/OS using its native make. The build system
5113 falls back to the BSD .include directive on that host platform.
5116 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
5117 SHA1 and plaintext password encodings. Make feature tests a
5118 bit more flexible. [William Rowe]
5120 *) Charset translation: mod_charset_lite handles output content
5121 translation in a filter. mod_charset_lite no longer ignores
5122 subrequests. A bunch of cruft related to BUFF's support for
5123 translating request and response bodies was removed.
5126 *) Move the addition of the CORE filter to the post_read_request
5127 hook in http_core.c. This removes the need to add the filter in
5128 multiple places and allows for an SSL module to be added much
5129 simpler. [Ryan Bloom]
5131 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
5132 Fix a security problem that affects certain configurations of
5133 mod_rewrite. If the result of a RewriteRule is a filename that
5134 contains expansion specifiers, especially regexp backreferences
5135 $0..$9 and %0..%9, then it may be possible for an attacker to
5136 access any file on the web server. [Tony Finch]
5138 *) Fix a bug where errors that are detected during early request parsing
5139 don't produce visible HTTP error messages at the browser, because
5140 the core_filter wasn't present. [Greg Ames]
5142 *) Provide apr_socklen_t as a portability aid.
5143 [Victor J. Orlikowski]
5145 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
5146 as well as a comment arg to the add, adduser and update cmds.
5147 update allows the user to clear or preserve pw/groups/comment.
5148 Fixed a bug in dbmmanage that prevented the check option from
5149 parsing a password followed by :group... text. Corrected the
5150 seed calcualation for Win32 systems, and added -lsdbm support.
5153 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
5156 *) Avoid a segfault when parsing .htaccess files. An
5157 uninitialized tree pointer was passed to ap_build_config().
5160 *) Change the way that inet_addr & inet_network are checked for
5161 in APR's configure process to allow BeOS BONE to correctly
5162 find them. With this change BeOS BONE now builds from source
5163 with no problems. [David Reid]
5165 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
5166 the end of the parameters to execve() was stored in the wrong
5167 location, overlaying the storage beyond the newargs[] array and
5168 also passing uninitialized storage to execve(), which would
5169 sometimes fail with EFAULT. [Jeff Trawick]
5171 *) Fix a bug parsing configuration file containers. With a sequence
5172 like this in the config file
5174 <IfModule mod_kilroy.c>
5177 <IfModule mod_lovejoy.c>
5182 the second container would be terminated at the blank line due to
5183 sediment in the buffer from reading the prior </IfModule> and an
5184 error message would be generated for the real </IfModule> for the
5185 second container. Also due to this problem, any two characters
5186 could be used for "</" in the close of a container.
5189 *) ap_add_filter prototype changed to remove the ctx pointer. The
5190 pointer still remains in the filter structure, but it can not be
5191 a part of the ap_add_filter prototype. The reason is that when
5192 the core uses AddFilter to add a filter to the stack it doesn't
5193 know how to allocate the ctx pointer, or even how much memory should
5194 be allocated. The filters will have to be responsible for allocating
5195 the ctx memory when they need it.
5198 *) Add an AddFilter directive. This directive takes a list of filters
5199 that should be activated for the requested resource.
5202 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
5203 some other platforms). [Jeff Trawick]
5205 *) Modify mod_include to be a filter. Currently, it has only been tested
5206 on actual files, but it should work for CGI scripts too.
5209 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
5210 writes. apr_flush() for Unix: handle interrupted writes.
5213 *) NameVirtualHost can now take "*" as an argument instead of
5214 an IP address. This allows you to create a purely name-based
5215 virtual hosting server that does not have any IP addresses in
5216 the configuration file and which ignores the local address
5217 of any connections. PR #5595, PR #4455 [Tony Finch]
5219 *) Fix some compile warnings in mod_mmap_static.c
5220 [Mike Abbott <mja@sgi.com>]
5222 *) Fix chunking problem with CGI scripts. The general problem was that
5223 the CGI modules were adding an EOS bucket and then the core added an
5224 EOS bucket. The chunking filter finalizes the chunked response when it
5225 encounters an EOS bucket. Because two EOS buckets were sent, we
5226 finalized the response twice. The fix is to make sure we only send one
5227 EOS, by utilizing a flag in the request_rec.
5230 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
5231 and Win32. Previously, the first read from an apr_file_t set up via
5232 apr_put_os_file() would return a '\0'. [Jeff Trawick]
5234 *) Mod_cgid now creates a single element bucket brigade, with a pipe
5235 bucket, instead of using BUFF's and ap_r*.
5238 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
5239 [Mike Abbott <mja@sgi.com>]
5241 *) Remove ap_bopenf from buff code. This required modifying the file_cache
5242 code to use APR file's directly instead of going through BUFFs.
5245 *) Fix compile break on some platforms for mod_mime_magic.c
5246 [John K. Sterling <sterling@covalent.net>]
5248 *) Fix merging of AddDefaultCharset directive.
5249 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
5251 *) Minor revamp of the rlimit sections of code. We now test
5252 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
5253 is now "available" even if the platform doesn't support
5254 the rlimit family (it's just a noop though). [Jim Jagielski]
5256 *) Migrate the pre-selection of which MPM to use for specific
5257 platforms to hints.m4, which contains (or should contain)
5258 all platform specific "hints". [Jim Jagielski]
5260 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
5263 *) Add tables with non-string/binary values to APR.
5266 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
5269 *) Update PCRE to version 3.2. [Ryan Bloom]
5271 *) Change the way buckets' destroy functions are called so that
5272 they can be more directly used when changing the type of a
5273 bucket in place. [Tony Finch]
5275 *) Add generic support for reference-counting the resources used by
5276 buckets, and alter the HEAP and MMAP buckets to use it. Change
5277 the way buckets are initialised to support changing the type of
5278 buckets in place, and use it when setting aside TRANSIENT buckets.
5279 Change the implementation of TRANSIENT buckets so that it can be
5280 mostly shared with IMMORTAL buckets, which are now implemented.
5283 Changes with Apache 2.0a6
5285 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
5287 *) Add a chunking filter to Apache. This brings us one step closer
5288 to removing BUFF. [Ryan Bloom]
5290 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
5291 added to the stack is the last filter to be called. [Ryan Bloom]
5293 *) Apache 2.0 has been completely documented using Scandoc. The
5294 docs can be generated by running 'make docs'. [Ryan Bloom]
5296 *) Add filtered I/O to Apache. This is based on bucket brigades,
5297 Currently the buckets still use BUFF under the covers, but that
5298 should change quickly. The only currently written filter is the
5299 core filter which just calls ap_bwrite. [The Apache Group]
5301 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
5302 built with thread support. [Jeff Trawick]
5304 *) Abort configuration if --with-layout was specified and there's
5305 no layout definition file. [Ken Coar]
5307 *) Add support for '--with-port=n' option to configure. [Ken Coar]
5309 *) Add support for extension methods for the Allow response header
5310 field, and an API routine for accessing r->allowed and the
5311 list of extension methods in a unified manner. [Ken Coar]
5313 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5314 [Rob Simonson <simo@us.ibm.com>]
5316 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5317 APACHE_XLATE builds. [Jeff Trawick]
5319 *) A configuration file parsing problem was fixed. When the
5320 configuration file started with an IfModule/IfDefine container,
5321 only the last statement in the container would be retained.
5324 Changes with Apache 2.0a5
5326 *) Perchild is serving pages after passing them to different child
5327 processes. There are still a lot of bugs, but this does work. I
5328 have made requests against the same installation of Apache, and had
5329 different servers use different user IDs to serve the responses.
5330 This change moves to using socketpair instead of an AF_UNIX socket.
5333 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5334 It can't seem to pass between child processes yet, but I think we
5335 are closer now than before. This moves us back to using Unix
5336 Domain Sockets. [Ryan Bloom]
5338 *) libapr functions and types renamed with apr_ prefix.
5339 #include "apr_compat.h" for 1.3.x backwards compat
5342 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5343 return the right information on the local socket address.
5344 [Gregory Nicholls <gnicholls@level8.com>]
5346 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5347 [Gregory Nicholls <gnicholls@level8.com>]
5349 *) Add an option to not detach from the controlling terminal without
5350 going into single process mode. This allows for much easier
5351 debugging of the process startup code. [Ryan Bloom]
5353 *) ab: don't use perror() to report the failure of an APR function.
5356 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5357 scoreboard on graceful restarts.
5360 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5361 An invalid ap_proc_t was passed to ap_create_process().
5364 *) Allow modules to register filters. Those filters are still
5365 never called, but this is a step in the right direction.
5366 [Ryan Bloom and Greg Stein]
5368 *) Register the mod_cgid daemon process for cleanup so that it is
5369 killed at termination if it does not die when the parent gets
5370 SIGTERM. This change is to fix occasional problems where the
5371 process stays around. Bugs in similar logic in mod_rewrite and
5372 mod_include were also fixed. [Jeff Trawick]
5374 *) Fix a bug in the time handling. Basically, we were imploding a time
5375 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5376 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5377 uses those two fields to adjust the time value. Because of the HTTP
5378 spec, both of those values can be zero'ed out safely. This fixes
5379 the bug correctly. [Ryan Bloom]
5381 *) Fix a couple of place in the Windows code where the wrong error
5382 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
5384 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5386 *) Added the APR_EOL_STR macro for platform dependent differences in
5387 logfiles and other raw text (such as all APR files). Fixes logfiles
5388 not terminated with cr/lf sequences in Win32. [William Rowe]
5390 *) Move all strings functions in APR to src/lib/apr/strings and create
5391 apr_strings.h for the prototypes. [Ryan Bloom]
5393 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5394 to repeat the syscall until we stop getting EINTR. I noticed a
5395 related problem at termination (SIGTERM) on FreeBSD when using
5396 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5397 implementation work properly with child init. Previously, ap_lock()
5398 was essentially a no-op because all children were using different
5399 locks and thus nobody ever blocked. [Jeff Trawick]
5401 *) The htdocs/ tree has been moved out of the CVS source tree into
5402 a separate area for easier development. This has NO EFFECT on
5403 end-users or Apache installations. [Ken Coar]
5405 *) Integrate the mod_dav module for WebDAV protocol handling. This
5406 adds the dav and dav_fs modules, the SDBM library, and additional
5407 XML handling utilities. [Greg Stein]
5409 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
5412 *) Update the lib/expat-lite/ library (bring forward changes from
5413 the Apache 1.3 repository). [Greg Stein]
5415 *) If sizeof(long long) == sizeof(long), then prefer long in APR
5416 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
5418 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
5419 machines where sendfile is detected, but nobody has written ap_sendfile.
5420 [Dave Hill <ddhill@zk3.dec.com>]
5422 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
5424 *) ab would start up more connections than needed, then quit when the
5425 desired number were finished. Also fixed a logic error involving
5426 ab keepalives. [Victor J. Orlikowski]
5428 *) WinNT: Implement non-blocking pipes with timeouts to communicate
5429 with CGIs. Apache 2.0a4 had non-blocking pipes but without
5430 timeouts (i.e, if a timeout was specified, the pipe reverted to
5431 a full blocking pipe). Now the behaviour is more in line with
5432 Unix non-blocking pipes.
5435 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
5436 cache open file handles along with accept socket reuse enables
5437 Apache 2.0 to serve non-keepalive requests for static files at
5438 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
5439 and Apache 2.0 will serve almost 1200 rps on my system).
5442 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
5443 supports two config directives, mmapfile (same behavious as
5444 mod_mmap_static) and cachefile. Use the cachefile directive
5445 to cache open file handles. This directive only works on systems
5446 that have implemented the ap_sendfile API. cachefile works today
5447 on Windows NT, but has not been tested on any flavors of Unix.
5450 *) Cleanup the configuration. With the last few changes the
5451 configuration process automatically:
5452 inherits information about how to build from APR. Allowing
5453 APR to inform Apache that it should or should not use -ldl
5455 Detects which mod_cgi should be used mod_cgi or mod_cgid,
5456 based on the threading model
5458 Apache calls APR's configure process before finishing it's
5459 configuration processing, allowing for more information flow
5464 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
5465 with non-zero argument makes the socket non-blocking. BeOS and
5466 OS/2 already worked this way. [Jeff Trawick]
5468 *) ap_close() now calls ap_flush() for buffered files, so write
5469 operations work a whole lot better on buffered files.
5472 *) Fix error messages issued from MPMs which explain where to change
5473 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
5476 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
5477 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
5478 now the way that the blocking state of a pipe is manipulated.
5479 ap_block_pipe() is gone. [Jeff Trawick]
5481 *) Correct the problem where the only local host name that the IP stack
5482 can discover are 'undotted' private names. If no fully qualified
5483 domain name can be identified, the default ServerName will be set to
5484 the machine's IP address string. A warning is always provided if the
5485 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
5487 *) Repair problems with config file processing which caused segfault
5488 at init when virtual hosts were defined and which caused ServerName to
5489 be ignored when there was no valid DNS setup. [Jeff Trawick]
5491 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
5493 *) Add ap_sendfile implementation for AIX
5494 [Victor J. Orlikowski]
5496 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
5497 apr_network_io.h, and apr_thread_proc.h.
5498 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
5500 *) Bring the allocation and pool debugging code back into a working
5501 state. This will need to be tested as so far it's only been used on
5504 *) Change configuration command setup to be properly typesafe when in
5505 maintainer mode. Note that this requires a compiler that can initialise
5506 unions. [Ben Laurie]
5508 *) Turn on buffering for config file reads. Part of this was to
5509 repair buffered I/O support in Unix and implement buffered
5510 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
5512 *) Win32: Fix problem where UTC offset was not being set correctly
5513 in the access log. Problem reported on news group by Jerry Baker.
5516 *) Fix segfault when reporting this type of syntax error:
5517 "</container> without matching <container> section", where
5518 container is VirtualHost or Directory or whatever.
5521 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
5522 Prevent the source code for CGIs from being revealed when
5523 using mod_vhost_alias and the CGI directory is under the document root
5524 and a user makes a request like http://www.example.com//cgi-bin/cgi
5525 as reported in <news:960999105.344321@ernani.logica.co.uk>
5528 *) Add support for the new Beos NetwOrking Environment (BONE)
5531 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
5532 final input char is incomplete; ap_bwrite_xlate() now handles
5533 incomplete final input chars. [Jeff Trawick]
5535 *) Yet another update to saferead/halfduplex stuff -- need to ensure
5536 that a bhalfduplex call occurs before logging or else DNS and
5537 such can delay the last packet of the response. [Dean Gaudet]
5539 *) Some syscall reduction in APR on unix -- don't seek when setting
5540 up an mmap; and don't fcntl() more than once per socket.
5543 *) When mod_cgid is started as root, the cgi daemon now switches
5544 to the configured User/Group (like other httpd processes)
5545 instead of continuing as root. [Jeff Trawick]
5547 *) The prefork MPM now uses an APR lock for the accept() mutex.
5548 It has not been getting a lock at all recently. httpd -V now
5549 displays APR's selection of the lock mechanism instead of the
5550 symbols previously respected by prefork. [Jeff Trawick]
5552 *) Change the mmap() feature test to check only for existence.
5553 The previous check required features not used by Apache.
5556 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
5557 sometimes mangled. The len parm to accept() was not
5558 initialized, leading sometimes to an endless loop of failed
5559 accept() calls on OS/390 and anywhere else that failed the call
5560 if the len was negative. Use <sys/un.h> for struct sockaddr_un
5561 instead of declaring it ourselves to fix a compilation problem
5562 on Solaris. [Jeff Trawick]
5564 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
5566 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
5568 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
5570 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
5571 initialization if ALLOC_DEBUG is defined; no known symptom
5572 otherwise. [Jeff Trawick]
5574 *) Fix typo in configure script when checking for mod_so. bash
5575 doesn't seem to have a problem but /bin/sh on Solaris does.
5576 Symptom: "./configure: test: unknown operator =="
5579 *) Rebind the Win32 NT and 9x services control into the MPM.
5580 All console, WinNT SCM and Win9x pseudo-service control code is
5581 now wrapped within the WinNT MPM.
5584 *) Make a copy of getenv("PATH") before storing for later use. Some
5585 getenv() implementations use the same storage for successive calls.
5586 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
5588 *) Server Tokens work in 2.0 again. This also propogates the change
5589 to allow just the product name in the server string using
5593 Changes with Apache 2.0a4
5595 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
5596 won't need to call it. [Greg Ames, Jeff Trawick]
5598 *) Move pre_config hook call to between configuration read and config
5599 tree walk. This allows all modules to implement pre_config hooks
5600 and know that they will be called at an appropriate time.
5603 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
5606 *) Add pre-config hooks back to all modules.
5609 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
5610 ContentDigest enabled and we can't/don't mmap the file.
5613 *) We now report the correct line number for syntax errors in config
5614 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
5616 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
5617 related bugs, and changed shmem/locking to use apr API. Shared-mem
5618 is currently disabled, however, because of problems with graceful
5619 restarts. [Ronald Tschalär]
5621 *) Fix corruption of IFS variable in --with-module= handling.
5622 Depending on the user's shell or customization thereof, there
5623 would be errors generating ap_config_auto.h later in the configure
5624 procedure. [Jeff Trawick]
5626 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
5627 isn't used (as in 1.3), except that on Unix it is now logged via
5628 ap_log_rerror() instead of by the child having STDERR_FILENO refer
5629 to the error log. [Greg Ames, Jeff Trawick]
5631 *) Add '-D' argument processing for run time configuration defines.
5634 *) Organize http_main.c as independent code, such that no code or
5635 global data is exported from it. WIN32 will dynamically link it
5636 to the server core, so this will prevent mutual dependency.
5639 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
5640 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
5643 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
5644 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
5646 *) Add mod_charset_lite for configuring character set translation.
5649 *) Add '-n' option to htpasswd to make it print its user:pw record
5650 on stdout rather than having to frob a text file. [Ken Coar]
5652 *) Fix saferead. Basically, we flush the output buffer if a read on the
5656 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
5657 a conversion is single-byte only. [Jeff Trawick]
5659 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
5660 the BeOS 5.0 documentation says that shutdown doesn't work yet.
5663 *) Fix some minor errors where pid was being manipulated as an int
5664 instead of the portable pid_t. [Roy Fielding]
5666 *) Fix some error log prints that were printing the pointer to a
5667 structure rather than the pid within the structure.
5668 [Jeff Trawick, Roy Fielding]
5670 *) ab: Fix a command-line processing bug; track bad headers in
5671 err_response; support reading headers up to 2K.
5672 [Ask Bjoern Hansen <ask@valueclick.com>]
5674 *) Fix ap_resolve_env() so that it handles new function added in a prior
5675 alpha (see "Added the capability to do ${ENVVAR} constructs in the
5676 config file.") as well as the constructs used by mod_rewrite.
5677 [Paul Reder <rederpj@raleigh.ibm.com>]
5679 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
5681 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
5682 APR to perform translation, instead of accessing the hard-coded tables
5683 in 1.3's ebcdic.c. [Jeff Trawick]
5685 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
5688 *) Add the ability to hook into the config file reading phase. Basically
5689 if a directive is specified EXEC_ON_READ, then when that directive is
5690 read from the config file, the assocaited function is executed. This
5691 should only be used for those directives that must muck with HOW the
5692 server INTERPRETS the config. This should not be used for directives
5693 that re-order or replace items in the config tree. Those changes should
5694 be made in the pre-config step.
5697 *) Add mod_example to the build system.
5700 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
5701 byte character sets. [Jeff Trawick]
5703 *) Pick up various EBCDIC fixes from 1.3 (from Martin
5704 Kraemer and Oliver Reh originally according to the change log).
5707 *) Fix a couple of problems in RFC1413 support (controlled by the
5708 IdentityCheck directive). Apache did not build the request string
5709 properly and more importantly Apache would loop forever if the
5710 would-be ident server dropped the connection before sending a
5711 properly terminated response. [Jeff Trawick]
5713 *) apxs works in 2.0.
5716 *) Reliable piped logs work in 2.0.
5719 *) Introduce a hash table implementation into APR to be used for
5720 replacing tables and other random data structures in Apache.
5723 *) Add some more error reporting to htpasswd in the case of problems
5724 generating or accessing the temporary file. Also, pass in a
5725 buffer if the implementation knows how to use it (i.e., if L_tmpnam
5726 is defined). [Ken Coar]
5728 *) Configure creates config.nice now containing your configure
5729 options. Syntax: ./config.nice [--more-options]
5732 *) Fix various return code problems in APR on Win32. For most of
5733 these, APR was returning APR_EEXIST instead of GetLastError()/
5734 WSAGetLastError(). [Jeff Trawick]
5736 *) Make piped logs work again in version 2.0
5739 *) Add VPATH support to UNIX build system of Apache and APR.
5742 *) Fix ap_tokenize_to_argv to respect the const arguments that are
5746 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
5747 Patch submitted to author.
5750 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
5751 /sbin in PATH on FreeBSD (all submitted to rse previously)
5754 *) Fix building Pthread-based MPMs on OpenBSD
5755 [Sascha Schumann] PR#26
5757 *) Fix ap_readdir() problem on systems where d_name[] field in
5758 struct dirent is declared with only one byte. (This problem only
5759 affected multithreaded builds.) This caused a segfault during
5760 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
5761 least). [Jeff Trawick]
5763 *) Fix some make-portability problems on at least Tru64, Irix
5765 [Sascha Schumann] PR#18, PR#39
5767 *) Add ap_sigwait() to support old-style sigwait() on systems
5768 like OS/390 and UnixWare.
5771 *) Add POSIX-thread flags for more platforms.
5774 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
5775 (on Unix, at least) to handle resolver errors. Fix a bug in
5776 the definition of APR_ENOMEM so that ap_strerror() can spit
5777 out the correct error message for it.
5780 Changes with Apache 2.0a3
5782 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
5785 *) API: *HOOK* macros now have an AP_ prefix
5788 *) Win32: Eliminate redundant calls to initialize winsock.
5789 [Tim Costello <timcostello@ozemail.com.au>]
5791 *) Fix bugs initializing ungetchar for pipes.
5792 [Chia-liang Kao <clkao@CirX.ORG>]
5794 *) The ab program in the src/support directory is now portable using
5798 *) Support directory is being compiled when the server is built
5801 *) The configure option --with-program-name has been added to allow
5802 developers to rename the executable at configure time. This also
5803 changes the name of the config files to match the executable's name.
5806 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
5807 containing version numbers. [Martin Pool]
5809 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
5810 Unix; access_log and error_log now created with these perms; non-
5811 Unix is unaffected [Jeff Trawick]
5813 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
5814 Replaced more magic numbers with MD5_DIGESTSIZE.
5815 [William Rowe, Roy Fielding]
5817 *) Win32: Get mod_auth_digest compiling and added to the Windows
5818 build environment. Not tested and I'd be suprised if it
5819 actually works. [Bill Stoddard]
5821 *) Revamp the Win32 make environment. Makefiles have been removed and
5822 Apache.dsw created to bring together all the pieces. Create new file
5823 os/win32/BaseAddr.ref to define module base addresses (to prevent
5824 dll relocation at start-up).
5825 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
5827 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
5828 of the \015, \012, and \015\012 constants with macros.
5831 *) Add ap_xlate_open() et al for translation of text between different
5832 character sets. The initial implementation requires iconv().
5835 *) More FAQs and answers from comp.infosystems.www.servers.unix.
5836 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5838 *) CGI output is being timed out now.
5841 *) Fix the problem with dieing quietly. dupfile now takes a pool which
5842 is used by the new apr file. There is no reason to create a new file
5843 with the same lifetime as the original file.
5846 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
5847 module base addresses. This will help shooting seg faults
5848 in the field. [William Rowe <wrowe@lnd.com>]
5850 *) Update Apache on Windows documentation. Add new document
5851 describing how to compile Apache on Windows.
5852 [William Rowe <wrowe@lnd.com>]
5854 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
5855 microseconds instead of seconds. Some storage leaks and other
5856 minor bugs in related code were fixed. [Jeff Trawick]
5858 *) Win32: First cut at getting mod_isapi working under 2.0
5859 [William Rowe <wrowe@lnd.com>]
5861 *) First stab at getting mod_auth_digest working under 2.0
5862 quick change summary:
5863 - moved the random byte generation (ap_generate_random_bytes) into APR
5864 - now uses ap_time_t
5865 - compiles and runs on linux
5867 [Brian Martin <bmartin@penguincomputing.com>]
5869 *) Win32: Move the space stripping of physical service names
5870 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
5871 unresolved symbol. Add dependency checking to the
5872 CreateService call to ensure TCPIP and AFP (winsock) is started
5874 [William Rowe <wrowe@lnd.com>]
5876 *) Win32: Add code to perform latebinding on functions that may
5877 not exist on all levels of Windows where Apache runs. This
5878 is needed to allow Apache to start-up on Win95/98. All calls
5879 to non portable functions should be protected with
5880 ap_oslevel checks to prevent runtime segfaults.
5881 [William Rowe <wrowe@lnd.com>]
5883 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
5885 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
5887 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
5888 This addresses PR 1623. Still need to address timing out runaway
5889 CGI scripts. [Bill Stoddard]
5891 *) Win32: Make ap_stat Windows 95/98 friendly
5892 [William Rowe <wrowe@lnd.com>]
5894 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
5895 always fail. Need to initialise the dwOSVersionInfoSize member of the
5896 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
5899 The patch also enhances ap_get_oslevel (and the associated enum) to
5900 handle selected service packs for NT4, and adds recognition for
5901 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
5902 we can use ReadFileScatter and WriteFileGather in readwrite.c.
5903 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
5905 *) Get mod_rewrite building and running, and mod_status building for Win NT
5906 [Allan Edwards <ake@raleigh.ibm.com>]
5908 *) Patch to port mod_auth_db to the 2.0 api and also to support
5909 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
5910 2.7.7. It should work with version 1 as well but I haven't tested it.
5911 [Brian Martin <bmartin@penguincomputing.com>]
5913 *) Get APR DSO code working under Windows. Includes cross platform
5915 [Tim.Costello@BTFinancialgroup.com]
5917 *) Fix some of the Windows APR time functions.
5920 *) FAQ changes related to tidying up historical documents on the web site.
5921 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5923 *) Move Windows DSO code into APR.
5926 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
5927 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
5928 at build time. At this point, the server will not compile on Windows because
5929 of the recent DSO commits. Fixing those next.
5930 [Bill Rowe & Bill Stoddard]
5932 *) Added error checking for file I/O APR routines.
5933 [Jon Travis <jtravis@covalent.net>]
5935 *) APR: Don't use the values of resolver error codes for the
5936 corresponding APR error codes. On Unix and Win32, return the
5937 proper APR error code after a resolver error. [Jeff Trawick]
5939 Changes with Apache 2.0a2
5941 *) Renamed the executable back to httpd on all platforms other
5945 *) Allow BeOS to survive restarts, log properly and a few
5946 small things it had problems with due to the way it setup
5947 users and groups. [David Reid]
5949 *) Get mod_rewrite working with APR locks
5950 [Paul Reder <rederpj@raleigh.ibm.com>]
5952 *) Actually remove the sempahore when the lock cleanup routine
5953 is called on BeOS. [David Reid]
5955 *) Clear hook registrations between reads of the config file.
5956 When DSOs are unloaded and re-loaded the old hook pointers may
5957 no longer be valid. This fix eliminates potential segfaults.
5958 [Allan Edwards <ake@raleigh.ibm.com>]
5960 *) Fix a problem with Sigfunc not being defined or bypassed
5961 if sigaction() wasn't found. [Jim Jagielski]
5963 *) Fix the locking mechanism on BSD variants. They now use fcntl
5964 locks. This allows the server to start and serve pages.
5967 *) First cut at getting the Win32 installer to work
5968 [William Rowe <wrowe@lnd.com>]
5970 *) Get htpasswd compiling under Windows
5971 [William Rowe <wrowe@lnd.com>]
5973 *) Change the log message for a bind() failure to show the
5974 interface and port number. [Jeff Trawick]
5976 *) Import the documentation from 1.3.12 and bring parts of it
5977 up-to-date with respect to the changes that have occurred
5981 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
5982 now logged correctly on BeOS.
5985 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
5986 Makefile.win includes the same user interface as the old
5988 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
5990 *) Win32 exec now uses COMSPEC environment string for command
5991 shell path resolution.
5992 [William Rowe <wrowe@lnd.com>] PR#3715
5994 *) Win32: ap_connect() was not returning correct error condition
5996 [Allen Prescott <allen@clanprescott.com>]
5998 *) Win32: ap_open() was broken on Win9x because an NT-specific
5999 flag was passed to CreateFile. ap_puts() added an unnecessary
6001 [Jeff Trawick <trawick@us.ibm.com>]
6003 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
6004 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
6005 confusing ee/et name and made all extensions language/dialect
6006 rather than country reflecting. Changed example files to
6007 explicit reflect the ISO charset and added a few common
6008 ones to the example config [dirkx]
6010 *) Extend external module capability. To use this, you call
6011 configure with --with-module=path/to/mod1,path/to/mod2,etc.
6014 *) Backported the various "default charset" fixes from 1.3.12,
6015 including the AddDefaultCharset directive. [Jim Jagielski]
6017 *) Added the capability to do ${ENVVAR} constructs in the
6018 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
6019 it does this on a line by line basis; i.e. if the envvar
6020 expands to something with spaces you have to protect it
6021 by adding quotes around it (Unless of course you expect it
6022 to contains more than one argument. Alternatively you
6023 can compile it on a per token basis; which is what people
6024 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
6025 hampers fancier hacks.
6026 [Dirk-Willem van Gulik]
6028 *) Changed the 'ErrorDocument' syntax in that it NO longer
6029 supports the asymetric
6031 ErrorDocument 301 "Some message
6033 Note the opening " quote, without a closing quote. It now
6034 has either the following syntaxes
6036 ErrorDocument XXX /local/uri
6037 ErrorDocument XXX http://valid/url
6038 ErrorDocument XXX "Some Message"
6040 The recognition heuristic is: if it has a space it
6041 is a message. If it has no spaces and starts with a /
6042 or is a valid URL then treat it that way. Otherwise it
6043 is assumed to be a message.
6045 This breaks backward compatibility but makes live a hell
6046 of a lot easier for GUI's and config file parsers.
6047 [Dirk-Willem van Gulik]
6049 *) Changed 'CacheNegotiatedDocs' from its present/not-present
6050 syntax into a 'on' or 'off' syntax. As it currently is the
6051 only non nesting token which uses NO_ARGS and thus is an
6052 absolute pain for any config interface automation. This
6053 breaks backward compatibility. [Dirk-Willem van Gulik]
6055 *) Add ability to add external modules to the build process. This is
6056 done with --with-module=/path/to/module. Modules can only be added
6057 as static modules at this point.
6060 Changes with Apache 2.0a1
6062 *) Fix FreeBSD 3.3 core dump.
6063 Basically, ap_initialize() needs to get called before
6064 create_process(), since create_process() passes op_on structure
6065 to semop() to get a lock, but op_on isn't initialized until
6066 ap_initialize() calls setup_lock(). Here is a slight
6067 rearrangement to main() which calls ap_initialize() earlier...
6068 [Jeff Trawick <trawick@us.ibm.com>]
6070 *) Enable Apache to use sendfile/TransmitFile API
6071 [Bill Stoddard, David Reid, Paul Reder]
6073 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
6077 *) Make file I/O and network I/O writev/sendv APIs consistent.
6078 Eliminate use of ap_iovec_t and use Posix struct iovec.
6079 Use seperate variable on ap_writev to set the number of iovecs
6080 passed in and number of bytes written.
6083 *) Adapt file iol to use APR functions. Replaced ap_open_file()
6084 with ap_create_file_iol(). ap_create_file_iol() requires that
6085 the file be opened prior to the call using ap_open().
6088 *) Port mod_include and mod_cgi to 2.0
6089 [Paul Reder, Bill Stoddard]
6091 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
6092 bytes_read/bytes_written is always valid (never -1). Plus
6093 some fixes to buff.c to correct problems introduced by the
6094 errno => ap_status_t changes a while back. Plus a fix to
6095 chunked encoding introduced right at the beginning of 2.0.
6098 *) Revamped UNIX build system to use autoconf and libtool.
6099 [Manoj Kasichainula, Sascha Schumann]
6101 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
6103 *) SECURITY: More rigorous checking of Host: headers to fix security
6104 problems with mass name-based virtual hosting (whether using mod_rewrite
6105 or mod_vhost_alias).
6106 [Ben Hyde, Tony Finch]
6108 *) Add back support for UseCanonicalName in <Directory> containers.
6109 [Manoj Kasichainula]
6111 *) Added APLOG_STARTUP log type. This allows us to write an error
6112 message without any of the date and time information. As a part
6113 of this change, I also removed all of the calls to fprintf(stderr
6114 and replaced them with calls to ap_log_error using APLOG_STARTUP
6115 writing to stderr is no longer portable, because we don't direct
6116 stderr to the error log on all platforms.
6119 *) Convert error logging functions to take errno as an argument.
6120 This makes our error logs more portable, because some Windows API's
6121 don't set errno. This change allows us to still output a valid
6122 message on all of our platforms.
6125 *) mod_mime_magic runs in 2.0-dev now.
6126 [Paul Reder <rederpj@raleigh.ibm.com>]
6128 *) sendfile has been added to APR.
6129 [John Zedlewski <zedlwski@Princeton.EDU>]
6131 *) buff.c has been converted to no longer use errno.
6132 [Manoj Kasichainula]
6134 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
6135 interface adaption to APR functions did it. [Martin Kraemer]
6137 *) Support DSOs properly on 32-bit HP-UX 11.0
6138 [Dilip Khandekar <dilip@cup.hp.com>]
6140 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
6141 [Ralf S. Engelschall]
6143 *) Cleaned APR build environment integration and bootstrap APR
6144 automatically for developers from src/Configure.
6145 [Ralf S. Engelschall]
6147 *) Fixed building of src/support/htpasswd.c
6148 [Ralf S. Engelschall]
6150 *) When generating the Location: header, mod_speling forgot
6151 to escape the spelling-fixed uri. (Forw-Port from 1.3)
6154 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
6156 *) Change all pools to APR contexts. This is the first step to
6157 incorporating APR into Apache. [Ryan Bloom]
6159 *) Move "handler not found" warning message to below the check
6160 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
6161 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
6163 *) Support line-continuation feature in config.option file and
6164 allow the loading of multiple option sections at once via
6165 ``--with-option=<section1>,<section2>,...''
6166 [Ralf S. Engelschall]
6168 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
6170 Changes with Apache MPM
6172 *) Use asynchronous AcceptEx() and a completion port to accept and
6173 dispatch connections to threads in Windows NT/2000.
6176 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
6179 *) Implement the APACI --with-option facility
6180 (per default used the config.option file).
6181 [Ralf S. Engelschall]
6183 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
6185 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
6186 Replace pre_connection module call with a register_hook call and
6187 implement pre_connection as a hook. The intent is that these hooks will
6188 be extended to allow Apache to be multi-protocol, and also to allow the
6189 calling order to be specified on a per-hook/per-module basis.
6192 *) Implement mpm_* methods as "modules". Each method gets its own
6193 subdir in src/modules (eg: src/modules/prefork). Selection
6194 of method uses Rule MPM_METHOD. [Jim Jagielski]
6196 *) Port the hybrid server from the apache-apr repository as
6197 mpm_mpmt_pthread. [Manoj Kasichainula]
6199 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
6200 amongst the unix MPMs.
6202 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
6203 signal handling for the new world order. [Dean Gaudet]
6205 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
6206 of alloc.c for now. [Dean Gaudet]
6208 *) Handle partial large writes correctly. [Ben Laurie]
6210 *) Eliminate conn_rec's pointer to server. All it knows is the base server
6211 based on IP/port. [Ben Laurie]
6213 *) Port a bunch of modules to the new module structure.
6214 ["Michael H. Voase" <mvoase@midcoast.com.au>]
6216 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
6218 *) Basic restructuring to introduce the MPM concept; includes various
6219 changes to the module API... better described by
6220 docs/initial_blurb.txt. [Dean Gaudet]
6222 Changes with Apache pthreads
6224 *) New buff option added: BO_TIMEOUT. It describes the timeout for
6225 buff operations (generally over a network).
6226 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
6228 *) Created http_accept abstraction. Added 4 new functions (not exported):
6229 init_accept(), begin_accepting_requests(), get_request(),
6230 stop_accepting_requests() [Bill Stoddard]
6232 *) Fix to ap_rprintf call that allows mod_info to work properly.
6233 [James Morris <jmorris@intercode.com.au>]
6235 *) user and ap_auth_type fields were moved from connection_rec to
6236 request_rec. [Ryan Bloom]
6238 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
6239 needed in a threaded server.
6241 *) Initial pthread implementation from from Dean's apache-nspr code.
6242 [Bill Stoddard, Ryan Bloom]
6245 Changes with Apache 1.3.9
6247 *) Remove bogus error message when a redirect doesn't set Location.
6248 Instead, use an empty string to avoid coredump if the error message
6249 was supposed to include a location. [Roy Fielding]
6251 *) Don't allow configure to include mod_auth_digest unless it is
6252 explicitly requested, even if the user asked for all modules.
6255 *) Translate module names to dll names for OS/2 so that they are no more
6256 than 8 characters long and have an extension of "dll" instead of "so".
6259 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
6260 Fix test-compile check to check for randbyte instead of trand32.
6261 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
6262 and tweak to make Amaya happier. [Ronald Tschalär]
6264 *) Ensure that the installed expat include files are world readable,
6265 just like the other header files. [Martin Kraemer]
6267 *) Fixed generated AddModule adjustments in APACI's `configure' script
6268 in order to allow (new) modules like mod_vhost_alias to be handled
6269 correctly (which was touched by the adjustments for mod_alias).
6270 [Ralf S. Engelschall]
6272 *) For binary builds, add -R flag to apachectl to work around the lack of
6273 an absolute path to the ./libexec directory where the libhttp.ep file
6274 is needed for SHARED_CORE architectures. [Randy Terbush]
6276 *) WIN32: Create the CGI script process as DETACHED. This may solve the
6277 problem observed by some Win95/98 users where they get CGI script
6278 output sent to the console. [Bill Stoddard]
6280 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
6281 routines are now called ap_base64* and are 'plain' (i.e., no
6282 pool access or anything clever). Inside util.c the routines acting
6283 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
6284 The oddly named ap_uuencode(), ap_uudecode() are kept around for
6285 now but deprecated. [dirkx]
6287 *) Clean up the base64 and SHA1 additions and make sure they are
6288 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
6289 files. [Roy Fielding]
6291 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
6292 checking. Allow compiling on VS 6.0. [Randy Terbush]
6294 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
6296 *) Use TestCompile to search for the truerand library (rather than blindly
6297 assuming its existence). If it is not found, complain (but do not
6298 exit - yet). [Martin Kraemer]
6300 *) We forgot to add the new exported function names to
6301 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
6303 *) Add description of -T command-line option to usage().
6304 [Ralf S. Engelschall]
6306 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
6307 searched only AFTER libap has been searched, because libap needs
6308 some symbols from libos. [Martin Kraemer]
6310 *) Fix conflict with original mod_digest related to the symbol of the
6311 module dispatch list (which has to be unique for DSO and follow the
6312 usual conventions for the installation procedure).
6313 [Ralf S. Engelschall]
6315 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6316 for other platforms as well. [Martin Kraemer]
6318 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6319 types by AP_LONG and replace reference to renamed variable 'ubuf'
6320 by 'buffer'. [Martin Kraemer]
6322 Changes with Apache 1.3.8 [not released]
6324 *) Flush the output buffer immediately after sending an error or redirect
6325 response, since the result may be needed by the client to abort a
6326 long data transfer or restart a series of pipelined requests.
6327 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
6329 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6330 [Ian Turner <iant@sequent.com>] PR#4735
6332 *) Local struct mmap in http_core.c conflicted with system structure
6333 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6335 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6336 [Ronald Tschalär <ronald@innovation.ch>]
6338 *) Fix a memory leak where the module counts were getting messed
6339 up across restarts. [David Harris <dharris@drh.net>]
6341 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6342 properly in mod_access.
6343 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
6345 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6346 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
6348 *) PORT: Support for compaq/tandem/com.
6349 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
6351 *) Added SHA1 password encryption support to easy migration from
6352 Netscape servers. See support/SHA1 for more information.
6353 Caused the separation of ap_md5.c into md5, sha1 and a general
6354 ap_checkpass.c with just a validate_passwd routine. Added a
6355 couple of flags to support/htpasswd. Some reuse of the to64()
6356 function; hence renamed to ap_to64().
6357 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
6359 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6360 with ASCII/EBCDIC conversions in "ident" query.
6361 [David McCreedy <McCreedy@us.ibm.com>]
6363 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6364 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6365 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6367 *) Fix SIGSEGV on some systems because the Vary fix below included
6368 a call to table_do with a variable argument list that was not
6369 NULL terminated. Replaced with better implementation. [Roy Fielding]
6371 Changes with Apache 1.3.7 [not released]
6373 *) The "Vary" response header field is now sanitised right before
6374 the header is sent back to the client. Multiple "Vary" fields
6375 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6376 "Vary: host, negotiate, host, accept-language") are reduced to
6377 single instances. This is a better solution than the force-no-vary
6378 one (which is still valid for clients that can't cope with Vary
6379 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6381 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
6383 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6384 least on Linux and FreeBSD for now.
6387 *) Win32: More apache -k restart work. Restarts are now honored
6388 immediately and connections in the listen queue are -not- lost.
6389 This is made possible by the use of the WSADuplicateSocket()
6390 call. The listeners are opened in the parent, duplicated, then
6391 the duplicates are passed to the child. The original listen sockets
6392 are not closed by the parent across a restart, thus the listen queue
6394 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6396 *) Fix handling of case when a client has sent "Expect: 100-continue"
6397 and we are going to respond with an error, but get stuck waiting to
6398 discard the body in the pointless hope of preserving the connection.
6399 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
6401 *) Fix 'configure' to work correctly with SysV-based versions of
6402 'tr' (consistent with Configure's use as well). [Jim Jagielski]
6404 *) apxs: Add "-S var=val" option which allows for override of CFG_*
6405 built-in values. Add "-e" option which works like -i but doesn't
6406 install the DSO; useful for editing httpd.conf with apxs. Fix
6407 editing code so that multiple invocations of apxs -a will not
6408 create duplicate LoadModule/AddModule entries; apxs can now be
6409 used to re- enable/disable a module. [Wilfredo Sanchez]
6411 *) Win32: Update the server to use Winsock 2. Specifically, link with
6412 ws2_32.lib rather than wsock32.lib. This gives us access to
6413 WSADuplcateSocket() in addition to some other enhanced comm APIs.
6414 Win 95 users may need to update their TCP/IP stack to pick up
6415 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
6416 [Bill Stoddard stoddard@raleigh.ibm.com]
6418 *) Win32: Redirect CGI script stderr (script debug info) into the
6419 error.log when CGI scripts fail. This makes Apache on Win32
6420 behave more like Unix.
6421 [Bill Stoddard stoddard@raleigh.ibm.com]
6423 *) Fixed `httpd' usage display: -D was missing.
6424 [Ralf S. Engelschall] PR#4614
6426 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
6427 [Ralf S. Engelschall] PR#4561, PR#4562
6429 *) OS/2: Fix problem with accept lock semaphores where server would die with
6430 "OS2SEM: Error 105 getting accept lock. Exiting!"
6431 [Brian Havard] PR#4505
6433 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
6434 [Randy Terbush <randy@covalent.net>]
6436 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
6437 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
6439 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
6440 command potentially _is_ GCC. [Ralf S. Engelschall]
6442 *) Fix apxs build issues on AIX
6443 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
6445 *) DocumentRoot Checking: Under previous versions, when Apache
6446 first started up, it used to do a stat of each DocumentRoot to
6447 see if it existed and was a directory. If not, then an error
6448 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
6449 does not exist, you will get error messages in error_log. If
6450 the '-t' command line option is used (to check the configuration)
6451 the check of DocumentRoot IS performed. An additional command
6452 line option, '-T', has been added if you want to avoid the
6453 DocumentRoot check even when checking the configuration.
6456 *) Win32: The query switch "apache -S" didn't exit after showing the
6457 vhost settings. That was inconsistent with the other query functions.
6458 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
6460 *) Win32: Changed behaviour of apache -k restart.
6461 Previously, the server would drain all connections in the stack's
6462 listen queue before honoring the restart. On a busy server, this
6463 could take hours. Now, a restart is honored almost immediately.
6464 All connections in Apache's queues are handled but connections in
6465 the stack's listen queue are discarded. Restart triggered by
6466 MaxRequestPerChild is unchanged.
6467 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6469 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
6470 the accept loop. Good for a 5% performance boost. Cleaned up
6471 parent/child process management code.
6472 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6474 *) Added ceiling on file size for memory mapped files.
6475 [John Giannandrea <jg@meer.net>] PR#4122
6477 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
6478 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
6479 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
6481 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
6482 use this at least for Expat. [Ralf S. Engelschall]
6484 *) Allow .module files to specify libraries with Lib:.
6487 *) Allow SetEnvIf[NoCase] to test environment variables as well
6488 as header fields and request attributes. [Ken Coar]
6490 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
6491 content-types are "text/html;parameters". PR#4524 [Ken Coar]
6493 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
6494 never accepted into any standard, and it opens up certain DoS
6495 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
6497 *) TestCompile updated. We can now run programs and output the
6498 results during the Configure process. [ Jim Jagielski]
6500 *) The source is now quad (long long) aware as needed. Specifically,
6501 the Configure process determines the correct size of off_t and
6502 *void. When the OS/platform/compiler supports quads, ap_snprintf()
6503 provides for the 'q' format qualifier (if quads are not available,
6504 'q' is silently "demoted" to long). [Jim Jagielski]
6506 *) When the username or password fed to htpasswd is too long, include the
6507 size limit in the error message. Also report illegal characters
6508 (currently only ':') in the username. Add the size restrictions
6509 to the man page. [Ken Coar]
6511 *) Fixed the configure --without-support option so it doesn't result in
6512 an infinite loop. [Marc Slemko]
6514 *) Piped error logs could cause a segfault if an error occured
6515 during configuration after a restart.
6516 [Aidan Cully <aidan@panix.com>] PR#4456
6518 *) If a "Location" field was stored in r->err_headers_out rather
6519 than r->headers_out, redirect processing wouldn't find it and
6520 the server would core dump on ap_escape_html(NULL). Check both
6521 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
6522 if Location isn't set. [Doug MacEachern, Ken Coar]
6524 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
6525 of the Expat 1.0.2 distribution. [Greg Stein]
6527 *) Replace regexec() calls with calls to a new API stub function
6528 ap_regexec(). This solves problems with DSO modules which use the regex
6529 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
6531 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
6532 environment variables can be set according to the protocol version
6533 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
6535 *) Add DSO support for OpenStep (Mach 4.2) platform.
6536 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
6538 *) Fix sed regex for generating ap_config_auto.h in src/Configure.

6547 *) Always log months in english format for %t in mod_log_config.
6548 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
6550 *) Support for server-parsed and multiview-determined ReadmeName and
6551 HeaderName files in mod_autoindex. Removed the restriction on
6552 "/"s in ReadmeName and HeaderName directives since the *sub_req*
6553 routines will deal with the access issues. (It's now possible to
6554 have {site|group|project|customer|...} wide readmes and headers.)
6555 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
6558 *) When stat() fails, don't assume anything about the contents of
6559 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
6561 *) It's OK for a semop to return EINTR, just loop around and try
6562 again. [Dean Gaudet]
6564 *) Fix configuration engine re-entrant hangups, which solve a
6565 handful of problems seen with mod_perl <Perl> configuration sections
6566 [Salvador Ortiz Garcia <sog@msg.com.mx>]
6568 *) Mac OS and Mac OS X Server now use the appropriate custom layout
6569 by default when building with APACI; allow for platform-specific
6570 variable defaults in configure. [Wilfredo Sanchez]
6572 *) Do setgid() before initgroups() in http_main; some platforms
6573 zap the grouplist when setgid() is called. This was fixed in
6574 suexec earlier, but the main httpd code missed the change.
6575 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579

6581 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
6583 *) OS/2: Add support for building loadable modules using DLLs.
6586 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
6589 *) Fix minor but annoying bug with the test for Configuration.tmpl
6590 being newer than Configuration so that it is less likely to fail
6591 when using APACI and shadow sources. [Wilfredo Sanchez]
6593 *) PORT: Add initial support for Mac OS (versions 10.0 and
6594 greater). Use Mac OS X Server layout for now. Clean up dyld code
6595 in unix/os.c, and don't install the dyld error handlers, which
6596 are no longer needed in Mac OS. [Wilfredo Sanchez]
6598 *) Rename Rhapsody layout to "Mac OS X Server". Change install
6599 locations to appropriate ones for user-built (as opposed to
6600 system) installs. [Wilfredo Sanchez]
6602 *) Modify mod_autoindex's handling of AddDescription so that the
6603 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
6605 *) Add functionality to the install-bindist.sh script created by
6606 binbuild.sh to use tar when copying distribution files to the
6607 serverroot. This allows upgrading an existing installation
6608 without nesting the new distribution in the old.
6610 install-bindist.sh now detects the local perl5 path to install
6611 apxs and dbmmanage with proper path to perl interpreter.
6613 Add an install-binsupport target which copies the source files
6614 for apxs and dbmmanage to bindist to allow these scripts to
6615 be properly installed relative to the destination serverroot.
6616 [Randy Terbush, Covalent Technologies, randy@covalent.net]

6741 [David McCreedy <mccreedy@us.ibm.com>]
6743 *) support/htpasswd now permits the password to be specified on the
6744 command line with the '-b' switch. This is useful when passwords
6745 need to be maintained by scripts -- particularly in the Win32
6746 environment. [Ken Coar]
6748 *) Win32: Win32 multiple services patch. Added capability to install and
6749 run multiple copies of apache as individual services.
6752 apache -n apache1 -i -f c:/httpd.conf
6753 Installs apache as service 'apache1' and associates c:/httpd.conf
6756 Starts apache1 service.
6758 Stops apache1 service
6761 apache -n apache2 -i
6762 Installs apache as service 'apache2'. httpd.conf is located under
6763 the default server root (/apache/conf/httpd.conf).
6765 Starts apache2 service.
6768 apache -n apache3 -i -d c:/program files/apache
6769 Install apache as service 'apache3' and sets server root to
6770 c:/program files/apache.
6773 apache -n apache2 -k restart
6774 Restart apache2 service
6776 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
6778 *) Correct the signed/unsigned character handling for the MD5 routines;
6779 mismatches were causing compilation problems with gcc -pedantic and
6780 in the TPF cross-compilation. [Ken Coar]
6782 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
6783 a roughly 5 fold speed up. [Brian Havard]
6785 *) proxy ftp: instead of using the hardwired string "text/plain" as
6786 a fallback type for files served by the ftp proxy, use the
6787 ap_default_type() function to determine the configured type.
6788 This allows for special configurations like
6789 <Directory proxy:ftp://some.host>
6790 DefaultType gargle/blurb
6792 Additionally, add the Content-Encoding: header to FTP proxy replies
6793 when the encoding is defined (by the AddEncoding directive).
6794 Because it was missing, it was almost impossible to browse compressed
6795 files using the FTP proxy (works now perfectly in Communicator).
6796 The ftp proxy now also returns the Date: and Server: header lines (if not
6797 much else... This code is "somewhat" broken) like normal requests do.
6800 *) Be more smart in APACI's configure script when determining the UID/GID
6801 for User/Group directives and use the determined UID/GID to initialize
6802 the permissions on the proxycachedir.
6803 [Dirk-Willem van Gulik, Ralf S. Engelschall]
6805 *) Changed the forking-prior-to-cleanup in the proxy module to first
6806 check wether it actually needs to collect garbage. This reduces
6807 the number of fork()s from one/request to just the odd one an hour.
6808 [Dirk-Willem van Gulik]
6810 *) Added proxy, auth and header support to src/support/ab.c. Added a
6811 README file to src/support/
6812 [Dirk-Willem van Gulik]
6814 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.
6815 [Ralf S. Engelschall] PR#4050
6817 *) Add support for DSO module compilation on BSD/OS 3.x.
6818 [Randy Terbush, Covalent Technologies]
6820 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
6821 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
6822 option) were substituted with $(TARGET).conf, etc. Same for other strings
6823 with dots where the dot wasn't matched as plain text.
6824 [Ralf S. Engelschall]
6826 *) PORT: Add support for FreeBSD 4.x [Ralf S. Engelschall]
6828 *) Fix verbose output of APACI configure (option -v)
6829 [Martin Kraemer, Ralf S. Engelschall]
6831 Changes with Apache 1.3.6
6833 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
6835 Changes with Apache 1.3.5 [not released]
6837 *) M_INVALID needed a value within the scope of METHODS so that unknown
6838 methods can be access controlled. [Roy Fielding] PR#3821
6840 *) Added PassAllEnv; makes server's entire environment available
6841 to CGIs and SSIs executed within directive's scope. [Ken Coar]
6843 *) ap_uuencode() always added two trailing '='s and encoding of
6844 8 bit characters on a machine with signed char may produced
6845 incorrect results. Additionally ap_uuencode() should now
6846 work correctly on EBCDIC platforms.
6847 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
6849 *) WIN32: Binary installer now runs the configuration DLL before
6850 the reboot prompt (which is only given if MSVCRT.DLL system
6851 DLL is new or updated). This should avoid the configuration
6852 directory being empty after installation. [Paul Sutton]
6853 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
6855 *) WIN32: Binary installer now creates Start menu options to start
6856 and stop Apache as a console application and to uninstall
6857 the Apache service on NT. [Paul Sutton] PR#3741
6859 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
6861 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
6862 have been reported with flock() locking (probably related to kernel
6863 version). [Dean Gaudet] PR#2723, 3531
6865 *) Using APACI, the main config file (usually httpd.conf) was
6866 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
6867 <wsanchez@apple.com>]
6869 *) PORT: AIX does not require the SHARED_CODE "hack"
6870 [Ryan Bloom <rbb@raleigh.ibm.com>]
6872 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
6873 avoidance code added in 1.3.3.
6874 [Dean Gaudet, Jeff Lewis <lewis@stanford.edu>] PR#3872
6876 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
6877 for 8-bit safeness. [Dean Gaudet]
6879 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
6880 because SPARCs have a small machine-specific maximum size for the Global
6881 Offset Table which is often exceeded when compiling one of the larger
6882 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
6884 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
6885 DSO/DLL section because it's a directive from mod_status and isn't
6886 available before the DLL of mod_status is loaded.
6887 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
6889 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
6890 continuation facility in Apache's configuration files which could
6891 lead to a buffer overflow situation.
6892 [Thomas Devanneaux <Thomas.Devanneaux@enst.fr>] PR#3617
6894 *) Make documentation and error messages of APACI's --activate-module=FILE
6895 option more clear. [Jan Wolter <janc@wwnet.net>] PR#3995
6897 *) Fix the gcc version check (for enabling the `inline' facility) to
6898 really support all future gcc versions >= 2.7 until we know more.
6899 [John Tobey <jtobey@banta-im.com>] PR#3983
6901 *) Let APACI's configure script correctly complain for unknown --enable-XXX
6902 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
6904 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
6905 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
6906 possible buffer overflows. [Ralf S. Engelschall]
6908 *) Remove no longer used non-API function ap_single_module_init().
6909 [Ralf S. Engelschall]
6911 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
6914 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
6915 to make platform installations easier. [Wilfredo Sanchez]
6917 *) In configure, do not append the target name to the directory path if
6918 the path already contains "apache". [Ralf S. Engelschall]
6920 *) SIGPIPE is now ignored by the server core. The request write routines
6921 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
6922 correctly check for output errors and mark the connection as aborted.
6923 Replaced many direct (unchecked) calls to ap_b* routines with the
6924 analogous ap_r* calls. [Roy Fielding]
6926 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
6927 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
6928 Furthermore map lookups for non-existent keys are now cached as well.
6929 Additionally "txt" maps are now parsed with simple string functions
6930 instead of using ap_pregcomp(). As a side effect a bug that prevented
6931 the usage of keys containing the "," character was fixed.
6932 The changes drastically improve the performance when large rewrite maps
6934 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
6936 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
6937 other than GET, and const'd the definition of method in request_rec.
6940 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
6942 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
6943 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
6945 *) Add %V to mod_log_config, this logs the hostname according to the
6946 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
6947 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
6949 *) Add support for \n and \t to mod_log_config, can be used to produce
6950 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
6952 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
6954 *) Added informative error messages for failed munmap() and fseek() calls
6955 in http_core.c. [John Bley, Roy Fielding]
6957 *) Added some informative error messages for some failed malloc()
6958 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
6960 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
6961 is removed. This allows <Directory proxy:*> directives to work and
6962 prevents invalid requests from killing the process.
6963 [Brian Havard <brianh@kheldar.apana.org.au>]
6965 *) Reorganised FAQ document.
6966 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
6968 *) src/support/: The ApacheBench benchmark program was overhauled by
6969 David N. Welton: you can now have it generate an HTML TABLE, presumably
6970 for integration into other HTML sources. David updated the ab man page
6971 as well and added some missing descriptions. Thanks!
6972 [David N. Welton <davidw@prosa.it>]
6974 *) Win32: The filename validity checker now allows filenames containing
6975 characters in the range 0x80 to 0xff (for example accented characters).
6976 [Paul Sutton] PR#3890
6978 *) Added conditional logging based upon environment variables to
6979 mod_log_config. mod_log_referer and mod_log_agent
6980 are now deprecated. [Ken Coar]
6982 *) Allow apache acting as a proxy server to relay the real
6983 reason of a failure to a client rather than the "internal
6984 server error" it does currently. The general exposure mechanism
6985 can be triggered by any module by setting the "verbose-error-to"
6986 note to "*"; this allows more than just proxy errors to be exposed.
6987 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
6989 *) Moved man pages for ab and apachectrl to section 8.
6990 [Wilfredo Sanchez, Roy Fielding]
6992 *) Added -S option to install.sh so that options can be passed to
6993 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
6995 *) Tweak modules Makefile generated by Configure so that it handles
6996 the test case of no modules being selected. [chaz@reliant.com]
6998 *) Added a <LimitExcept method ...> sectioning directive that allows
6999 the user to assign authentication control to any HTTP method that
7000 is *not* given in the argument list; i.e., the logical negation
7001 of the <Limit> directive. This is particularly useful for controlling
7002 access on methods unknown to the Apache core, but perhaps known by
7003 some module or CGI script. [Roy Fielding, Tony Finch]
7005 *) Prevent apachectl from complaining if the PIDFILE exists but
7006 does not contain a process id, as might occur if the server is
7007 being rapidly restarted. [Wilfredo Sanchez]
7009 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
7011 *) Entity tag comparisons for If-Match and If-None-Match were not being
7012 performed correctly -- weak tags might cause false positives. Also,
7013 strong comparison wasn't properly enforced in all cases.
7014 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
7016 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
7019 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
7020 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
7022 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
7023 to util.c for parsing an HTTP header field value to extract the next
7024 list item, taking into account the possible presence of nested comments,
7025 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
7026 insignificant whitespace and lowercases non-quoted tokens.
7027 [Roy Fielding] PR#2065
7029 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
7030 code different from 500. This allows the proxy to, e.g., return
7031 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
7033 *) Fix ordering of language variants for the case where the traditional
7034 negotiation algorithm is being used with multiple language variants
7035 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
7037 *) Do not round the TCN quality calculation to 5 decimal places,
7038 unlike RFC 2296, because the calculation might need 12 decimal places
7039 to get the right result. [Roy Fielding]
7041 *) Remove unused code to disable transparent negotiation when
7042 negotiating on encoding only, as we now handle encoding too
7043 (though this is nonstandard for TCN), remove charset=ISO-8859-1
7044 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
7045 some debugging statements within mod_negotiation. [Koen Holtman]
7047 *) Fixed a rare memory corruption possibility in mod_dir if the index
7048 file is negotiable and no acceptable variant can be found.
7049 [Dean Gaudet, Roy Fielding, Martin Kraemer]
7051 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
7052 searching the Win32 registry for script interpreters.
7055 *) Win32: The compiled-in default filename for the error log is now
7056 error.log, which matches the default in the distributed httpd.conf.
7059 *) Win32: Any error messages from -i or -u command line options are now
7060 displayed on the console output rather than sent to the error log.
7061 Also the "Running Apache..." message is not output unless Apache is
7062 going to serve requests. [Paul Sutton]
7064 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
7065 and use a private significator ('$apr1$') to mark passwords as
7066 being smashed with our own algorithm. Also abstract the password
7067 checking into a new ap_validate_password() routine. [Ken Coar]
7069 *) Win32: The filename validity checker now allows "COM" but refuses
7070 access to "COM1" through "COM4". This allows filenames such
7071 as "com.name" to be served. [Paul Sutton] PR#3769.
7073 *) BS2000: Adapt to the new ufork() system call interface which will
7074 make subtasking easier on the OSD/POSIX mainframe environment.
7077 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
7078 ap_compat.h. [David White <david@persimmon.com>] PR#3725
7080 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
7081 use `.db' instead of `.pag' not only for FreeBSD, but also when
7082 the NDBM library looks like Berkeley-DB based.
7083 [Ralf S. Engelschall] PR#3773
7085 *) Add ability to handle DES or MD5 authentication passwords.
7086 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
7088 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
7090 *) SECURITY: Avoid some buffer overflow problems when escaping
7091 quoted strings. (This overflow was on the heap and we believe
7092 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
7094 *) Let src/Configure be aware of CFLAGS options starting with plus
7095 signs as it's the case for the HP/UX compiler.
7096 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
7098 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
7099 and check to see if the tar we wind up with supports '-h'.
7100 [Jim Jagielski] PR#3671
7102 *) A consistent and conservative style for all shell scripts has been
7103 implemented. Basically, all shell string tests use the traditional
7104 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
7105 to protect against bare null variable strings (ie: wrapping both
7106 sides with double quotes and prepending 'x'). 'x' was chosen
7107 because it's more universal and hopefully easier for old shell
7108 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
7111 *) The status module now prints out both the main server generation as
7112 well as the generation of each process. Also, the vhost info is
7113 printed with '?notable'. [Jim Jagielski]
7115 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
7116 and this makes its functions available to things in src/support.
7119 Changes with Apache 1.3.4
7121 *) Renamed macros status_drops_connection to ap_status_drops_connection
7122 and vestigial scan_script_header to ap_scan_script_header_err,
7123 mostly for aesthetic reasons. [Roy Fielding]
7125 *) The query switch "httpd -S" didn't exit after showing the
7126 vhost settings. That was inconsistent with the other query functions.
7129 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
7130 filename to the end of the STANDARD_MODULE_STUFF. Its
7131 presence at the beginning prevented reporting of the filename
7132 for modules compiled before 1 January 1999. [Ken Coar]
7134 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
7135 to detect and prevent access to special DOS device file names.
7136 [Paul Sutton, Ken Parzygnat]
7138 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
7139 and Makefile_win32_debug.txt (debug build) that work on Win95.
7140 Run each of the following from the src directory:
7141 nmake /f Makefile_win32.txt # compiles normal build
7142 nmake /f Makefile_win32.txt install # compiles and installs
7143 nmake /f Makefile_win32.txt clean # removes compiled junk
7144 nmake /f Makefile_win32_debug.txt # compiles debug build
7145 nmake /f Makefile_win32_debug.txt install
7146 nmake /f Makefile_win32_debug.txt clean
7149 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
7150 to build binary distributions. [Lars Eilebrecht]
7152 *) IndexOptions SuppressColumnSorting only turned off making
7153 the column headers anchors; you could still change the display
7154 order by manually adding a '?N=A' or similar query string to the
7155 URL. Now SuppressColumnSorting locks in the sort order so
7156 it can't be overridden this way. [Ken Coar]
7158 *) Added IndexOrderDefault directive to supply a default sort order
7159 for FancyIndexed directory listings. [Ken Coar] PR#1699
7161 *) Change the ap_assert macro to a variant that works on all platforms.
7162 [Richard Prinz <richard.prinz@cso.net>] PR#2575
7164 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
7165 search for an underscore on dlsym() (as it's already the case
7166 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
7168 *) Small fix for mod_env.html: The module was documented as to be _not_
7169 compiled into Apache per default, although it _IS_ compiled into
7170 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
7172 *) Instead of fixing a bug in the generation procedure for config.status (a
7173 backslash was missing) we remove the bug together with it's complete
7174 context because the special cases of the past can now no longer occur
7175 because of the recent magic for the --with-layout default.
7176 [Ralf S. Engelschall] PR#3590
7178 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
7179 making sure the src/support/ tools are _forced_ to be build last (they
7180 depend on other libraries).
7181 [Markus Theissinger <markus.theissinger@gmx.de>]
7183 *) Fix installation procedure: Now that os-inline.c is actually used (a
7184 recently fixed bug prevented this) we need to also install os-include.c
7185 in addition to os.h into the PREFIX/include/ location or building of
7186 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
7188 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
7189 allow us to distinguish between a garbled DSO (or even a file which isn't
7190 an Apache module DSO at all) and a DSO which doesn't match the current
7191 Apache API. [Ralf S. Engelschall] PR#3152
7193 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
7194 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
7195 match case insensitive (this especially avoids nasty patterns like
7196 `[tT][eE][sS][tT]'). Second two additional internal map functions
7197 `escape' and `unescape' were added which can be used to escape/unescape
7198 to/from hex-encodings in URLs parts (this is especially useful in
7199 combination with map lookups).
7200 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
7202 *) Renamed the macro escape_uri() to ap_escape_uri() which was
7203 forgotten (because it was a macro) in the symbol renaming process.
7204 [Ralf S. Engelschall]
7206 *) Fix some inconsistencies related to the scopes of directives. The only
7207 user visible change is that the directives `UseCanonicalName' and
7208 `ContentDigest' now use the (more correct) `Options' scope instead of
7209 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
7211 *) Using DSO, the Server token was being mangled. Specifically, the
7212 module's token was being added first before the Apache token. This
7213 has been fixed. [Jim Jagielski]
7215 *) Major overhaul of mod_negotiation.c, part 2.
7216 - properly handle "identity" within Accept-Encoding.
7217 - allow encoded variants in RVSA negotiation and let them appear in
7218 the Alternates field using the non-standard "encoding" tag-list.
7219 - fixed both negotiation algorithms so that an explicitly accepted
7220 encoding is preferred over no encoding if "identity" is not
7221 included within Accept-Encoding.
7222 - added ap_array_pstrcat() to alloc.c for efficient concatenation
7223 of large substring sequences.
7224 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
7227 *) Major overhaul of mod_negotiation.c, part 1.
7228 - cleanups to mod_negotiation comments and code structure
7229 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
7230 support for everything in the upcoming HTTP/1.1
7231 revision (draft-ietf-http-v11-spec-rev-06.txt).
7232 - language tag matching also handles tags with more than 2
7234 - empty Accept, Accept-Language, Accept-Charset headers are
7235 processed correctly; previously an empty header would make all
7236 values acceptable instead of unacceptable.
7237 - allowed for q values in Accept-Encoding
7238 - added support for transparent content negotiation (rfc2295 and
7239 rfc2296) (though we do not implement all features in these drafts,
7240 e.g. no feature negotiation). Removed old experimental version.
7241 - implemented 'structured entity tags' for better cache correctness
7242 (structured entity tags ensure that caches which can deal with Vary
7243 will (eventually) be updated if the set of variants on the server
7245 - this involved adding a vlist_validator element to request_rec
7246 - this involved adding the ap_make_etag() function to the global API
7247 - modified guessing of charsets used by Apache negotiation algorithm
7248 to guess 'no charset' if the variant is not a text/* type
7249 - added code to sort multiviews variants into a canonical order so that
7250 negotiation results are consistent across backup/restores and mirrors

7279 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
7282 *) Update APXS manual page: some -q option arguments were missing
7283 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
7285 *) Cleanup the command line options: `-?' was documented to show
7286 the usage list but does it with an error because `?' is not a valid
7287 command. OTOH a lot of users expect `-h' to print such a usage list and
7288 instead are annoyed for ages by our huge unreadable list of directives.
7289 So we now changed the command line options this way:
7291 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
7292 very similar to the popular linker option.
7294 Intent: while -l gives the small list of modules, -L now gives the
7295 large list of directives implemented by these modules. This is also
7296 consistent with -v (short version info) and -V (large version info).
7298 Intent: it's now the expected option ;-)
7299 The manual page was adjusted accordingly.

7302 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
7303 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
7305 *) Removed recently introduced bugs and disfigurements in APACI:
7306 o fixed argument line processing: using $args was broken: It was not
7307 initialized and using args="$args $apc_option" and even args="$args
7308 \"$apc_option\"" fails in the second processing round for any arguments
7309 containing whitespaces. The only correct way is to use the construct
7310 "$@" (but not possible here) or iterate _both_ times over the implicit
7311 argument line (no argument to for-loop) which is what we now use.
7312 o make --with-layout=Apache the default without creating
7313 redundancy (copying the --with-layout block in the argument parsing
7314 loop). We achieve this by using the "$@" construct together with the
7315 `set' command to prepend --with-layout=Apache to the command line in
7316 case --with-layout is not used.
7317 o fixed auto-suffix handling now that config.layout exists.
7318 Paths which are auto-suffixed are marked with a trailing plus sign in
7319 config.layout and every path now can be marked this way (not only the
7320 four paths for which we do it currently). Additionally the suffix is
7321 no longer a static one. Instead it's now `/<target>' where <target> is
7322 the argument of the --target option or per default `httpd'.
7323 o allow also tabs (and only spaces) where we match whitespaces
7324 o various fixes and cleanups related to used shell coding style
7325 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7326 o trimmed output of --help to fit into 80 columns

7389 procedure of mod_rewrite: very long keys were truncated.
7390 [Ralf S. Engelschall]
7392 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
7393 identifier, currently "Apache" and "GNU" are pre-defined in the file
7394 config.layout. Custom layouts are possible by using FILE:ID as the
7395 argument where the layout ID is taken from FILE.
7397 The config.layout file consists of <Layout ID>..</Layout> sections
7398 where inside those sections "path_variable: path_value" pairs can be
7399 specified. These lines are converted to path_variable='path_value'.
7401 *) Add a DefaultLanguage directive so that files missing a language
7402 extension (e.g., .fr, .de) can be labelled as being some other
7403 default language. DefaultLanguage can appear in <Directory> and
7404 <Files> containers as well as .htaccess files. [Paul Sutton]

7521 mod_foo with the begin of the module list, i.e. it `moves' the module to
7522 the begin of the list (gives it lowest priority). And second foo:END

7732 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
7733 platform to make the braindead HPUX linker happy. Notice, for the module
7734 DSOs we don't have to use this, because these are loaded manually (and
7735 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

7746 *) Make PrintPath work generically instead of having one version
7747 strictly for OS/2. [Jim Jagielski, Brian Havard]
7749 *) Fix the recently introduced C header file checking: We now use the C
7750 pre-processor pass only (and no longer the complete compiler pass) to
7751 determine whether a C header file exists or not. Because only this way
7752 we're safe against inter-header dependencies (which caused horrible
7753 portability problems). The only drawback is that we now have a CPP
7754 configuration variable which has to be determined first (we do a similar
7755 approach as GNU Autoconf does here). When all fails the user still has
7756 the possibility to override it manually via APACI or src/Configuration.
7757 As a fallback for the header check itself we can directly check the
7758 existance of the file under /usr/include, too.

7809 *) mod_expires will now act on content that is not sent from a file
7810 on disk. Previously it would never add an Expires: header to

7830 proxy immune to these errors (and ignore the duplicates, but log
7831 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
7833 *) The <IfModule and <IfDefine block starting directives now only
7834 allow exactly one argument. Previously, the optional negation
7835 character '!' could be separated by whitespace without a syntax
7836 error being reported, albeit defeating the IfModule functionality
7837 (enclosed directives would ALWAYS be executed). By using the
7838 stricter syntax, these hard-to-track errors can be avoided.
7841 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
7842 cause the standalone FancyIndexing directive to logically OR
7843 into any existing IndexOptions settings rather than wiping
7844 them out. [Ken Coar]
7846 *) Changes in ftp proxy: make URL parsing simpler by using the
7848 + Add display of the "current directory" in cases where it's
7849 different from the supplied path (e.g., ftp://user@host/ lives
7850 in /home/user, not in /, therefore clicking on "../" in the
7851 starting directory might send us to /home/).
7852 + When ftp login fails, (esp. when a user name was part of the
7853 URL already), we now return [401 Unauthorized ] to allow the
7854 browser to pop up an authorization dialog. This makes passwords
7855 slightly less visible (they don't appear in the regular log files)
7856 and implements a functionality that other www proxy servers
7860 *) Triggered by the recent "Via:" header changes, the proxy module would
7861 dump core for replies with invalid headers (e.g., duplicate
7862 "HTTP/1.0 200 OK" lines). These errors are now logged and the
7863 core dump is avoided. Also, broken replies are not cached.

7936 Eliminate O(n^2) space DoS attacks (and other O(n^2)
7937 cpu time attacks) in header parsing. Add ap_overlap_tables(),
7938 a function which can be used to perform bulk update operations
7939 on tables in a more efficient manner.
7942 *) SECURITY: Added compile-time and configurable limits for
7943 various aspects of reading a client request to avoid some simple
7944 denial of service attacks, including limits on maximum request-line
7945 size (LimitRequestLine), number of header fields (LimitRequestFields),

7998 This is done by determining a subset of LIBS which can be safely used for
7999 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
8000 disabled for all platforms to avoid problems with this (experimental)

8232 [Ralf S. Engelschall] PR#871, PR#1318
8234 *) Add a flag so ap_fnmatch() can be used for case-blind pattern matching.
8235 [Ken Coar, Dean Gaudet]
8237 *) WIN32: Don't collapse multiple slashes in PATH_INFO.
8238 [Ben Laurie, Bill Stoddard <wgstodda@us.ibm.com>] PR#2274
8240 *) WIN32 SECURITY: Eliminate trailing "."s in path components. These are
8241 ignored by the Windows filesystem, and so can be used to bypass security.
8242 [Ben Laurie, Alexei Kosut].
8244 *) We now attempt to dump core when we get SIGILL. [Jim Jagielski]
8246 *) PORT: remove broken test for MAP_FILE in http_main.c.
8247 [Wilfredo Sanchez <wsanchez@apple.com>]
8249 *) PORT: Change support/apachectl to use "kill -0 $pid" to test if the
8250 httpd is running. This should be more portable than figuring out
8251 which of three dozen different versions of "ps" are installed.
8254 *) WIN32: If we can't figure out how to execute a file in a script
8255 directory, bail out of the request with an error message. [W G Stoddard]
8257 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
8258 these are treated by Win32 as if they are ".." but are not detected by
8259 other machinery within Apache. This is something of a kludge but
8260 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
8262 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
8263 pools and thus pollutes libap (until the pool stuff is moved there).
8266 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
8267 but case-insensitive platforms). New #define for this added to conf.h
8268 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455
8270 *) Enable DSO support for OpenBSD in general, not only for 2.x, because it
8271 also works for OpenBSD 1.x. [Ralf S. Engelschall]
8273 *) PORT: Fix compilation problem on ARM Linux.
8274 [Sam Kington <sam@illuminated.co.uk>] PR#2443
8276 *) Let APACI's configure script determine some configuration parameters
8277 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
8278 remove some of the classical hurdles for new users when setting up
8279 Apache. This is done per default because it is useful for the average
8280 user. Package authors can use the --without-confadjust option to disable
8281 these configuration adjustments.
8282 [Ralf S. Engelschall]
8284 *) Added an EXTRA_DEPS configuration parameter which can be used
8285 to add an extra Makefile dependency for the httpd target, for instance
8286 to external third-party libraries, etc.
8287 [Ralf S. Engelschall]
8289 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
8290 as <IfModule>..</IfModule> sections) which can be used to skip or process
8291 contained commands dependend of ``-D PARAMETER'' options on the command
8292 line. This can be used to achieve logical conditions like <IfDefine
8293 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
8294 and thus especially can be used for conditionally loading DSO-based
8295 modules via LoadModule, etc. [Ralf S. Engelschall]
8297 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
8299 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
8301 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
8302 truncated which forced following HTTP headers to be data in the HTTP
8303 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
8306 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
8307 in top-level configure script to avoid sed fails on some platforms (for
8308 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
8309 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
8311 *) Improve performance of directory listings (mod_autoindex) by comparing
8312 integer keys (last-modified and size) as integers rather than converting
8313 them to strings first. Also use a set of explicit byte tests rather
8314 than strcmp() to check for parent directory-ness of an entry. Oh, and
8315 make sure the parent directory (if displayed) is *always* listed first
8316 regardless of the sort key. Overall performance winnage should be good
8317 in CPU time, instruction cache, and memory usage, particularly for large
8318 directories. [Ken Coar]
8320 *) Add a tiny but useful goody to APACI's configure script: The generation
8321 of a config.status script (as GNU Autoconf does) which remembers the used
8322 configure command and hence can be used to restore the configuration by
8323 just re-running this script or for remembering the configuration between
8325 [Ralf S. Engelschall]
8327 *) Add httpd -t (test) option for running configuration syntax tests only.
8328 If something is broken it complains and exits with a return code
8329 non-equal to 0. This can be used manually by the user to check the Apache
8330 configuration after editing and is also automatically used by apachectl
8331 on (graceful) restart command to make sure Apache doesn't die on restarts
8332 because of a configuration which is now broken since the last (re)start.
8333 This way `apachectl restart' can be used inside cronjobs without having
8334 to expect Apache to be falling down. Additionally the httpd -t can be run
8335 via `apachectl configtest'.
8336 [Ralf S. Engelschall] PR#2393
8338 *) Minor display fix for "install" target of top-level Makefile:

8355 functions which are in libdld under HPUX 9/10.
8356 [Ralf S. Engelschall] PR#2378
8358 *) Make sure the "install" target of the top-level Makefile doesn't break
8359 because of a return code of 1 from an "if" (for instance under braindead
8360 Ultrix the result code of an "if" construct is 1 if the "then" clause
8361 didn't match). [Ralf S. Engelschall]
8363 *) Add an additional "dummy" target to the "$(LIB)" target in generated
8364 modules/xxx/Makefile's to avoid problems with SVR4 Make under "full-DSO"
8365 situation (no libxxx.a built, only mod_xxx.so's) where LIB and OBJS are
8366 empty. [Ralf S. Engelschall, Dean Gaudet, Martin Kraemer]

8453 [Ralf S. Engelschall] PR#2307
8455 *) Changes usage of perror/fprintf to stderr to more proper ap_log_error

8469 *) Propagate environment to CGI scripts correctly in Win32.
8470 [W G Stoddard <wgstodda@us.ibm.com>] PR#2294
8472 *) Some symbol renaming:
8473 ap_spawn_child_err became ap_spawn_child
8474 ap_spawn_child_err_buff became ap_bspawn_child
8475 spawn_child was obsoleted and moved to compat.h
8478 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
8479 programs: ap_spawn_child_err() is used and the Win32 case now uses
8480 CreateProcess() instead of a low-level execl() (which caused problems in
8481 the past under Win32).
8482 [Ralf S. Engelschall]
8484 *) A few cosmetics and trivial enhancements to APXS to make the
8485 generated Makefile more user friendly. [Ralf S. Engelschall]
8487 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
8488 was updated to use the normal apache error processing, thereby allowing
8489 proxy errors to be treated by ErrorDocument's as well. For this
8490 purpose, a new module-to-core communication variable "error-notes"
8491 was introduced; the proxy (and possibly other modules) communicates
8492 its error text using this variable. Its content is copied to a new
8493 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
8494 The old proxy special error routine ap_proxy_log_uerror()
8495 was replaced by regular ap_log_error() calls, many messages were made
8497 [Martin Kraemer] PR#494, 1259
8499 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
8502 *) Transform the configure message "You need root privileges for suEXEC"
8503 from a fatal error into a (more friendly) warning because the building
8504 ("make") of Apache we can allow, of course. Root privileges are needed
8505 only for the installation step ("make install"). So make sure the
8506 user is aware of this fact but let him proceed as long as he can.
8507 [Ralf S. Engelschall] PR#2288
8509 *) Renamed three more functions to common ap_ prefix which we missed at the
8510 Big Symbol Renaming because they're #defines and not real C functions:
8511 is_default_port(), default_port(), http_method().
8512 [Ralf S. Engelschall]
8514 *) A zero-length name after a $ in an SSI document should cause
8515 just the $ to be in the expansion. This was broken during the
8516 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
8518 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
8519 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252

8522 used under AIX) because of recent changes to function names.
8523 [Ralf S. Engelschall]
8525 Changes with Apache 1.3b7
8527 *) Make sure a MIME-type can be forced via a RewriteRule even when no
8528 substitution takes place, for instance via the following rule:
8529 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
8530 requested by users in the past to force a single script without a .cgi
8531 extension and outside any cgi-bin dirs to be executed as a CGI program.
8532 [Ralf S. Engelschall] PR#2254
8534 *) A fix for protocol issues surrounding 400, 408, and
8535 414 responses. [Ed Korthof]
8537 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
8539 *) Fix discrepancy in proxy_ftp.c which was causing failures when
8540 trying to connect to certain ftpd's, such as anonftpd.
8541 [Rick Ohnemus <rick@ecompcon.com>]
8543 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
8544 logfile instead of fiddling around itself with child spawning stuff.
8545 [Ralf S. Engelschall]
8547 *) Made RefererIgnore case-insensitive.
8549 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
8552 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
8553 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
8556 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
8558 *) Fix support script `dbmmanage': It was unable to handle some sort
8559 of passwords, especially passwords with "0" chars.
8560 [Ralf S. Engelschall] PR#2242
8562 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
8563 [Ben Laurie] PR#2238
8565 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
8566 library), so CGI handling has been changed to use Win32 native handles
8567 instead of C file descriptors.
8568 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
8570 *) The proxy cache would store an incorrect content-length in the cached
8571 file copy after a cache update. That resulted in repeated fetching
8572 of the original copy instead of using the cached copy.
8573 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
8575 *) The Makefiles assumed that DSO files are build via $(LD). This
8576 is broken for two reasons: First we never defined at least LD=ld
8577 somewhere to make sure this works (it was silently assumed that most Make
8578 provide a built-in LD definition - ARGL!) and second using the generic LD
8579 variable is not the truth. Instead a special variable named LD_SHLIB is
8580 reasonable because although "ld" is usually the default, the command for
8581 building DSO files can be "libtool" or even "cc" on some systems.
8582 [Ralf S. Engelschall]
8584 *) Replace the AddVersionPlatform directive with ServerTokens which
8585 provides for more control over the format of the Server:
8586 header line. SERVER_SUBVERSION is no longer supported;
8587 all module should use the ap_add_version_component()
8588 API function instead. [Jim Jagielski]
8590 *) Support for the NCR MP/RAS 3.0
8591 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
8593 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
8594 not retrieved in src/Configure and thus was not useable.
8595 [Ralf S. Engelschall]
8597 *) Various Makefile consistency cleanups:
8598 - make OSDIR also automatically be relative to src/ like INCDIR
8599 - SUBDIRS is now generated in src/Makefile only and not in
8600 Makefile.config because it is a local define for this location.
8601 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
8602 any Makefile but make sure that at least the "-K inline" is kept in
8604 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
8605 - updated the dependencies theirself
8606 - removed not existing SHLIB variable from "clean" targets
8607 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
8608 already exists and OBJS_PIC are also just plain objects and have not
8609 directly to do with "shared" things. The only difference is that they
8610 contain PIC. So OBJS_PIC is the more canonical name.
8611 - Updated the Makefile-dependency lines for OBJS_PIC
8612 - Removed the Makefile-dependency line in Configure to avoid double
8614 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
8615 of xxx.lo as GNU libtool does with its PIC objects
8616 - reduce local complexity in modules Makefile.tmpl by moving the last
8617 existing target "depend" to the generation section in Configure, too.
8618 - removed the historical $(SPACER) which was used in the past together
8619 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
8620 is no longer needed.
8621 - force the build and run of the gen_xxx programs under main/ as the
8622 first step before building the objects because it looks cleaner
8623 [Ralf S. Engelschall]
8625 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
8628 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
8631 *) WIN32: Don't force ISAPI headers to finish with \n.
8632 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
8634 *) When opening "configuration" files (like httpd.conf, htaccess
8635 and htpasswd), Apache will not allow them to be non-/dev/null
8636 device files. This closes a DoS hole. At the same time,
8637 we use ap_pfopen to open these files to handle timeouts.
8638 [Jim Jagielski, Martin Kraemer]
8640 *) Apache will now log the reason its httpd children exit if they exit
8641 due to an unexpected signal. (It requires a new porting define,
8642 SYS_SIGLIST, which if defined should point to a list of text
8643 descriptions of the signals available. See PORTING.) [Dean Gaudet]
8645 *) WIN32: chdir() doesn't make sense in a multithreaded environment
8646 like WIN32. Before, Win32 CGI's could have had sporadic failures
8647 if a chdir call from one thread was made between another chdir call
8648 and a spawn in another thread. So, for now don't chdir for CGI scripts
8649 in WIN32. The current CGI "spec" is unclear as to whether it's
8650 necessary. Long-term fix is to either serialize the chdir/spawn combo
8651 or use WIN32 native calls to spawn a process. This temp fix was
8652 necessary to remove this as a showstopper for 1.3's release.
8655 *) Cleanup the suEXEC support in APACI and make it more safe:
8656 1. Add big fat hint in INSTALL about risks and to read the
8657 htdocs/manual/suexec.html document before using the suexec-related
8659 2. Make sure the user has at least provided one --suexec-xxxx option
8660 (specifies suEXEC parameters) in addition to --enable-suexec option.
8661 If only --enable-suexec is given APACI stops with a hint to INSTALL
8662 and htdocs/manual/suexec.html documents.
8663 3. Provide two additional --suexec-xxxx options to make the suEXEC
8664 configuration complete (especially for package maintainers who else
8665 had to patch the source tree) by providing ways to configure minimal
8666 UID/GID and safe PATH, too.
8667 [Ralf S. Engelschall]
8669 *) Cleanup of the `configure --shadow' process:
8670 - make sure the configure script creates its temporary files in the
8671 shadow tree to avoid conflicts with parallel configure runs
8672 - removed unnecessary option "-r" from "rm" call for Makefiles
8673 - make sure the configure scripts creates the shadow-wrapper Makefile
8674 only when no shadow trees already exists
8675 - make sure "make distclean" removes the shadow-wrapper Makefile but only
8676 when no more shadow trees exists
8677 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
8678 as fast (in the past it needed 70sec, now it runs just 38sec)
8679 - make sure CVS does not complain about the created files
8680 Makefille.<gnutriple> and directories src.<gnutriple>
8681 [Ralf S. Engelschall]
8683 *) Added the ap_add_version_component() API routine and the
8684 AddVersionPlatform core directive. The first allows modules to
8685 declare themselves in the Server response header field value,
8686 augmenting the SERVER_SUBVERSION define in the Configuration file
8687 with run-time settings (more useful in a loadable-module environment).
8688 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
8689 into the server version string. [Ken Coar] PR#2056
8691 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
8694 *) Emit the "Accept-Range" header for the default handler.
8695 [Brian Behlendorf] PR#1464
8697 *) Add a note to httpd.conf-dist that apache will on some systems fail
8698 to start when the Group # is set to a negative or large positive value.
8701 *) Make sure the module execution order is correct even when some modules
8702 are loaded under runtime (`LoadModule') via the DSO mechanism:
8703 1. The list of loaded modules is now a dynamically allocated one
8704 and not the original statically list from modules.c
8705 2. The loaded modules are now correctly setup by LoadModule for
8706 later use by the AddModule command.
8707 3. When the DSO mechanism for modules is used APACI's `install'
8708 target now enables all created `LoadModule' lines per default because
8709 this is both already expected by the user _and_ needed to avoid
8710 confusion with the next point and reduces the Makefile.tmpl complexity
8711 4. When the DSO mechanism for modules is used, APACI's `install'
8712 target now additionally makes sure the module list is reconstructed
8713 via a complete `ClearModuleList+AddModule...' entry.
8714 5. The support tool `apxs' now also makes sure an AddModule command
8715 is added in addition to the LoadModule command.
8716 6. The modules.c generation was extended to now contain two
8717 comments to make sure no one is confused by the confusing terminology
8718 of loading/linking (we use load=link+load & link=activate instead of
8719 the obvious load=activate & link=link :-( )
8720 This way now there is no longer a difference under execution time between
8721 statically and dynamically linked modules.

8724 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
8725 Big Symbol Renaming. [Ralf S. Engelschall]
8727 *) Add a comment to mod_example.c showing the format of a FLAG command
8730 *) Standardized the time format in mod_status to match that of other
8731 places in the code (e.g. DATE_GMT). PR#1551
8733 *) Fix handling of %Z in timefmt strings for those platforms with no time
8734 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
8737 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
8738 feature compatible with 'UseCanonicalName off' by changing
8739 r->server->server_hostname to ap_get_server_name(). And I changed some
8740 functions which use r->server->port to use ap_get_server_port() instead,
8741 because if there's no Port directive in the config r->server->port is 0.
8744 *) get/set_module_config are trivial enough to be better off inline. Worth
8745 1.5% performance boost. [Dean Gaudet]
8747 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
8748 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
8751 *) [BS2000 security] BS2000 needs an extra authentication to initialize
8752 the task environment to the unprivileged User id. Otherwise CGI scripts
8753 would have a way to gain super user access. [Martin Kraemer]
8755 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
8756 absolute path, only log base name of logging source as is done
8757 in unix. [Martin Kraemer]
8759 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
8760 the encoding type from the Accept-Encoding header (if it's there)
8761 and use it in the response, as that's probably what it'll be expecting.
8762 [Ronald.Tschalaer@psi.ch]
8764 *) Fix to mod_alias: translate_alias_redir is dealing with
8765 a URI, not a filename, so the check for drive letters for win32
8766 and emx is not necessary. [Dean Gaudet]
8768 *) WIN32: Allow .cmd as an executable extension.

8774 *) Child processes can now "signal" (by exiting with a status
8775 of APEXIT_CHILDFATAL) the parent process to abort and
8776 shutdown the server if the error in the child process was
8777 fatal enough. [Jim Jagielski]

8786 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
8788 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
8791 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
8792 Additionally the checks for finding the vendor DSO library were moved
8793 from mod_so.c to Configure because first it needs $PLAT etc. and second
8794 mod_so already uses an abstraction layer and does not fiddle with the
8795 vendor functions itself.
8796 [Jens-Uwe Mager, Ralf S. Engelschall]
8798 *) PORT: Some optimization defines for NetBSD
8799 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
8801 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
8802 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
8804 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
8805 AIX variants should work fine, too. Even AIX 3.x should work). This is
8806 accomplished by using the free DSO emulation code from Jens-Uwe Mager
8807 which we put into a os/unix/os-dso-aix.c file.
8808 [Ralf S. Engelschall]
8810 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
8811 that we should use NET_SIZE_T == int but the include files force size_t.
8812 [Ralf S. Engelschall]
8814 *) Fix two bugs in select() handling in http_main.c.
8817 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
8818 is unset (as it is in situations like timeouts) where it is unclear
8819 whether errno is set or not. [Martin Kraemer]
8821 *) Just having APACI's localstatedir is too general and not enough for most
8822 of the systems. 1.3b6 again required manual APACI patches by package
8823 maintainers from Red Hat and FreeBSD because for their filesystem layout a
8824 little bit more flexibility in configuring the paths is needed. Hence we
8825 provide three additional configure options (--runtimedir, --logfiledir,
8826 --proxycachedir) which now can be used for more granular adjustments if
8827 --localstatedir is not enough to fit the particular needs. As a nice
8828 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
8829 [Ralf S. Engelschall]
8831 *) Make the install root for "make install" in APACI's Makefile overrideable
8832 by package authors. This way we are even more friendly to package
8833 maintainers (especially Debian and Red Hat) who build for the real prefix
8834 via "configure --prefix=/<real>" but use a different local prefix via
8835 "make root=/tmp/apache install" for rolling the package without bristling
8836 the target location on their system.
8837 [Ralf S. Engelschall]
8839 *) Workaround sed limitations in APACI's configure script by now
8840 substituting in chunks of 50 commands (because for instance HPUX's vendor
8841 sed has a limit of max. 98 commands)
8842 [Ralf S. Engelschall] PR#2136
8844 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
8845 [Ralf S. Engelschall] PR#2140
8847 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
8848 RENAMING process because they are defined as pre-processor macros instead
8849 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
8850 [Ralf S. Engelschall]
8852 *) Workaround braindead AWK's when generating ap_config.h: The split() and
8853 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
8854 [Ralf S. Engelschall] PR#2139
8856 *) Various bugfixes and cleanups for the APACI configure script:
8857 o fix IFS handling for _nested_ situation
8858 o fix Perl interpreter search: take first one found instead of last one
8859 o fix DSO consistency check
8860 o print error messages to stderr instead of stdout
8861 o add install-quiet for --shadow situation to Makefile stub
8862 o reduce complexity by avoiding sed-hacks for rule and module list loops
8863 [Ralf S. Engelschall]
8865 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
8867 *) Make sure the input field separator (IFS) shell variable is explicitly
8868 initialized correctly before _every_ `for' loop and also restored after
8869 the loops. [Ralf S. Engelschall]
8871 *) Make sure that "make install" doesn't overwrite the `mime.types' and
8872 `magic' files from an existing Apache installation. Because people often
8873 customize these for own MIME and content types.
8874 [Ralf S. Engelschall]
8876 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
8877 [Peter Galbavy, Ralf S. Engelschall] PR#2109
8879 *) Fix the path to the ScoreBoardFile in the install-config target, too.
8880 [Ralf S. Engelschall] PR#2105
8882 *) Let "configure" clear out the users parameters (provided as shell
8883 variables) to avoid side-effects in "src/Configure" when the user
8884 exported them (which is not needed, but some users do it).
8885 [Ralf S. Engelschall] PR#2101
8887 *) Provide backward compatibility from some old src/Configuration.tmpl
8888 parameter names to the canonical Autoconf-style shell variable names. For
8889 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
8890 but a hint message is displayed. [Ralf S. Engelschall]

8893 CGI scripts from an existing Apache installation.
8894 [Ralf S. Engelschall, Jim Jagielski] PR#2084
8896 *) Make `configure --compat' more "compatible" by first
8897 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
8898 second by making sure the "avoid-bristling-suffix" /apache is not
8899 appended to sysconfdir, datadir, localstatedir and includedir when
8900 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]

8908 *) Fix the path to the MimeMagicFile in the install-config target, too.
8909 [Ralf S. Engelschall] PR#2089
8911 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
8913 *) If you start apache with the -S command line option it will dump
8914 out the parsed vhost settings. This is useful for folks trying
8915 to figure out what is wrong with their vhost configuration.
8916 (Other dumps may be added in the future.) [Dean Gaudet]
8918 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
8919 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
8922 *) Because /usr/local/apache is the default prefix the ``configure
8923 --compat'' option no longer has to set prefix, again. This way the
8924 --compat option honors a leading --prefix option. [Lars Eilebrecht]
8926 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
8927 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
8928 to avoid "discard const" warnings. [Ralf S. Engelschall]
8930 *) If a specific handler is set for a file yet the request still
8931 ends up being handled by the default handler, log an error
8932 message before handling it. This catches things such as trying
8933 to use SSIs without mod_include enabled. [Marc Slemko]
8935 *) Fix error logging for the startup case where ap_log_error() still uses
8936 stderr as the target. Now the default log level is honored here, too.
8937 [Ralf S. Engelschall]
8939 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
8940 long" errors when generating the MODULES entry for src/Makefile
8941 [Ben Hyde, Ralf S. Engelschall]
8943 *) Make sure src/Configure doesn't complain about the old directory
8944 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
8946 Changes with Apache 1.3b6
8948 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
8950 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
8951 interface via the similar but proprietary HP/UX shl_xxx-style system
8952 calls. [Ralf S. Engelschall]
8954 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
8955 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
8956 Make. [Ralf S. Engelschall]
8958 *) ++++ THE BIG SYMBOL RENAMING ++++
8959 To avoid symbol clashes with third-party code compiled into the server,
8960 we globally applied the prefix "ap_" to the following classes of
8962 - Apache provided general functions (e.g., ap_cpystrn)
8963 - Public API functions (e.g., palloc, bgets)
8964 - Private functions which we can't make static (because of
8965 cross-object usage) but should be (e.g., new_connection)
8966 For backward source compatibility a new header file named compat.h was
8967 created which provides defines for the old symbol names and can be used
8968 by third-party module authors.
8971 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
8972 problem under SVR4 is that there is no command flag to force the linker
8973 to export the global symbols of the httpd executable therewith they are
8974 available to the DSO's. Instead of problematic hacks like creating a
8975 dummy.so file (containing dummy references to all global symbols) the
8976 httpd binary is linked against, we use a clean trick stolen from Perl 5:
8977 Placing the Apache core code itself into a DSO library named libhttpd.so.
8978 This way the global symbols _HAVE_ to be exported and thus are available
8979 to any manually loaded DSO's under runtime. To reduce the impact to the
8980 user to null we go even further and create a stub httpd executable which
8981 automatically keeps track of the DSO library loading itself and thus
8982 hides the complete mechanism from the user. Although the generation of
8983 this DSO library is automatically triggered for platforms which
8984 essentially need it (mostly all SVR4-derivates) it can be also enabled
8985 manually via the Rule SHARED_CORE. This can be interesting in the future
8986 where we perhaps exploit this libhttpd.so mechanism for providing nifty
8987 features like graceful upgrades, or whatever.
8988 [Ralf S. Engelschall, Martin Kraemer]
8990 *) Build the libraries before building the rest of the tools. [Ben Hyde]
8992 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
8993 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
8994 conventions while "clean" removes only stuff created by "all" targets,
8995 "distclean" additionally removes the stuff from the configuration
8996 process. This way "make distclean" (hence the name) provides a fresh
8997 source tree as it was for distribution.
8998 [Ralf S. Engelschall]
9000 *) Allow top-level (APACI) Makefile to break on build errors
9001 the same way the src/ subtree Makefiles breaks on them by replacing the
9002 initial APACI sed-subdir-display-kludge with a more clean
9003 variable-passing-solution: variable SDP can optionally hold the subdir
9004 prefix which is consistently used for displaying the subdir movement.
9005 This way even the top-level Makefile can stop correctly on errors as the
9006 user expects. [Ralf S. Engelschall]
9008 *) Fixed ordering of argument checks for RewriteBase directive.
9009 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
9011 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
9012 indicating that a module is being compiled for dynamic loading. Also
9013 remove #define IS_MODULE from modules and add SHARED_MODULE define
9014 to the mak/dsp files. [Alexei Kosut]
9016 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
9017 since we are now logging APLOG_WARNING by default. [Roy Fielding]
9019 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
9021 *) Add documentation file and src/Configuration.tmpl entry for the
9022 experimental mod_mmap_static module. Because although it is and marked as
9023 an experimental one it is distributed and thus should be documented and
9024 prepared for configuration the same way as all others modules.
9025 [Ralf S. Engelschall]
9027 *) Add query (-q) option to apxs support tool to be able to manually query
9028 specific settings from apxs. This is needed for instance when you
9029 manually want to access Apache's header files and you need to assemble
9030 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
9031 [Ralf S. Engelschall]
9033 *) Now src/Configure uses a fallback strategy for the shared object support
9034 on platforms where no explicit information is available: If a Perl
9035 installation exists we ask it about its shared object support and if it's
9036 the dlopen-style one we shamelessly guess the compiler and linker flags
9037 for creating shared objects from Perls knowledge. Of course, the user is
9038 warning about what we are doing and informed that he should send us
9039 the guessed flags when they work. [Ralf S. Engelschall]
9041 *) Provide APACI --without-support option to be able to disable the build
9042 and installation of the support tools from the src/support/ area.
9043 Although its useful to have these installed per default we should provide
9044 a way to compile and install without them for backward-compatibility.
9045 [Ralf S. Engelschall]
9047 *) Add of the new APache eXtenSion (apxs) support tool for building and
9048 installing modules into an _already installed_ Apache package through the
9049 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
9050 this approach actually doesn't need the Apache source tree. The
9051 (APACI-installed) server package is enough, because this now includes the
9052 Apache C header files (PREFIX/include) and the new APXS tool
9053 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
9054 module authors to build their Apache modules _OUTSIDE_ the Apache source
9055 tree while avoiding them to fiddle around with the totally platform
9056 dependend way of compiling DSO files. The tool supports all ranges of
9057 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
9058 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
9059 on-the-fly generate a minimalistic Makefile and sample module for the
9060 first step to provide both a quick success event and to demonstrate the
9061 APXS mechanism to module authors. [Ralf S. Engelschall]
9063 *) Fix core dumps in use of CONNECT in proxy.
9064 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
9066 *) Modify the log directives in httpd.conf-dist files to use CustomLog
9067 so that users have examples of how CustomLog can be used.
9070 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
9071 the Apache distribution tree. Until Apache 1.3 there was no real
9072 out-of-the-box batch-capable build and installation procedure for the
9073 complete Apache package. This is now provided by a top-level "configure"
9074 script and a corresponding top-level "Makefile.tmpl" file. The goal is
9075 to provide a GNU Autoconf-style frontend which is capable to both drive
9076 the old src/Configure stuff in batch and additionally installs the
9077 package with a GNU-conforming directory layout. Any options from the old
9078 configuration scheme are available plus a lot of new options for flexibly
9079 customizing Apache. [Ralf S. Engelschall]
9081 *) The floating point ap_snprintf code wasn't threadsafe.
9082 Had to remove the HAVE_CVT macro in order to do threadsafe
9083 calling of the ?cvt() floating point routines. [Dean Gaudet]
9085 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
9087 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
9088 [Jim Jagielski] PR#1901
9090 *) BUG: Configure was using TCC and CC inconsistently. Make sure
9091 Configure knows which CC we are using. [Jim Jagielski]
9093 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
9094 was defined in a parent directory. [Lars Eilebrecht]
9096 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
9097 a generic printf-style routine that can call arbitrary output
9098 routines. Use this to replace http_bprintf.c. Add new routines
9099 psprintf(), pvsprintf() which allocate the exact amount of memory
9100 required for a string from a pool. Use psprintf() to clean up
9101 various bits of code which used ap_snprintf()/pstrdup().
9104 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
9105 ap_snprintf() has different semantics and formatting codes than
9106 snprintf(). [Dean Gaudet]
9108 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
9109 is necessary on at least Solaris where the /etc/rc?.d scripts
9110 are run with these signals ignored, and "SIG_IGN" settings are
9111 maintained across exec().

9132 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
9135 *) After a SIGHUP the listening sockets in the parent weren't
9136 properly marked for closure on fork().
9137 [Jürgen Keil <jk@tools.de>] PR#2000
9139 *) Allow %2F in two situations: 1) it is in the query part of the URI,
9140 therefore not exposed to %2F -> '/' translations and 2) the request
9141 is a proxy request, so we're not dealing with a local resource anyway.
9142 Without this, the proxy would fail to work for any URL's with
9143 %2f in them (occurs quite often in
9144 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
9146 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
9148 *) Make the shared object compilation command more portable by avoiding
9149 the direct combination of `-c' & `-o' which is not honored by some
9150 compilers like UnixWare's cc. [Ralf S. Engelschall]
9152 *) WIN32: the proxy was creating filenames missing the last four
9153 characters. While this normally doesn't stop anything from
9154 working, it can result in extra collisions.

9157 *) Now mod_proxy uses the response string (in addition to the response status
9158 code) from the already used FTP SIZE command to setup the Content-Length
9159 header if available. [Ralf S. Engelschall] PR#1183
9161 *) Reanimated the (still undocumented) proxy receive buffer size directive:
9162 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
9163 name was really too generic, added documentation for this directive to
9164 the mod_proxy.html and corrected the hyperlink to it in the
9165 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
9167 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
9168 faster [Martin Kraemer]
9170 *) Make Configure die when you give it an unknown command switch.
9173 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
9174 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
9175 and per default compiled support programs have manual pages - just to
9176 document our stuff a little bit more and to be able to do really
9177 Unix-like installations ;-) [Ralf S. Engelschall]
9179 *) Major cleanups to the Configure script to make it and its generated
9180 Makefiles again readable and maintainable: add SRCDIR option, removed
9181 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
9182 generated sections, consequently added Makefile headers with inheritance
9183 information, added subdir movement messages for easier following where
9184 the build process currently stays (more verbose then standard Make, less
9185 verbose than GNU make), same style to comments in the Configure script,
9186 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
9188 *) Add the new ApacheBench program "ab" to src/support/: This is derived
9189 from the ZeusBench benchmarking program and can be used to determine the
9190 response performance of an Apache installation. This version is
9191 officially licensed with Zeus Technology, Ltd. See the license agreement
9192 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.

9195 *) API: Various core functions that are definately not part of the API
9196 have been made static, and a few have been marked API_EXPORT. Still
9197 more have been marked CORE_EXPORT and are not intended for general
9198 use by modules. [Doug MacEachern, Dean Gaudet]
9200 *) mod_proxy was not clearing the Proxy-Connection header from
9201 requests; now it does. This did not violate any spec, however

9211 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
9213 *) Clean up some undocumented behavior of mod_setenvif related to
9214 "merging" two SetEnvIf directives when they match the same header
9215 and regex. Document that mod_setenvif will perform comparisons in
9216 the order they appear in the config file. Optimize mod_setenvif by
9217 doing more work at config time rather than at runtime.
9220 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
9221 to allow for modules to overrule them and to reduce redefinition
9222 warnings [Jim Jagielski]
9224 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
9227 *) Making the hard-coded cross-module function call mime_find_ct() (from
9228 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
9229 checking is really called even for proxy requests except for URLs with
9230 HTTP schemes (because there we can optimize by not running the type
9231 checking hooks due to the fact that the proxy gets the MIME Content-type
9232 from the remote host later). This change cleans up mod_mime by removing
9233 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
9234 especially unbundles mod_proxy and mod_mime. This way they both now can
9235 be compiled as shared objects and are no longer tied together.
9236 [Ralf S. Engelschall]
9238 *) util.c cleanup and speedup. [Dean Gaudet]
9240 *) API: Clarification, pstrndup() will always copy n bytes of the source

9243 *) Mark module command_rec and handler_rec structures const so that they
9244 end up in the read-only data section (and are friendlier to systems

9248 port is in the appropriate range. [Ben Hyde]
9250 *) Performance improvements to invoke_handler().
9251 [Dmitry Khrustalev <dima@bog.msu.su>]
9253 *) Added support for building shared objects even for library-style modules
9254 (which are built from more than one object file). This now provides the
9255 ability to build mod_proxy as a shared object module. Additionally
9256 modules like mod_example are now also supported for shared object
9257 building because the generated Makefiles now no longer assume there is at
9258 least one statically linked module. [Ralf S. Engelschall]
9260 *) API: Clarify usage of content_type, handler, content_encoding,
9261 content_language and content_languages fields in request_rec. They
9262 must always be lowercased; and the strings pointed to shouldn't
9263 be modified (you must copy them to modify them). Fix a few bugs
9264 related to this. [Dean Gaudet]
9266 *) API: Clarification: except for RAW_ARGS, all command handlers can
9267 treat the char * parameters as permanent, and modifiable. There
9268 is no need to pstrdup() them. Clean up some needless pstrdup().
9271 *) Now mod_so keeps track of which module shared objects with which names
9272 are loaded and thus avoids multiple loading and unloading and irritating
9273 error_log messages. [Ralf S. Engelschall]
9275 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
9276 environment variable in the apache core. But that tweaking interferes
9277 with mod_setenv. So don't tweak if the user has specified an explicit
9278 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888

9288 *) Various improvements to the configuration and build support for compiling
9289 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
9290 OSF1 support with GCC and vendor compilers was added. This way shared
9291 object support is now provided out-of-the-box for FreeBSD, Linux,
9292 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!

9295 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
9296 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
9297 and USE_OS2_SCOREBOARD. [Dean Gaudet]
9299 *) Fix one more special locking problem for RewriteMap programs in
9300 mod_rewrite: According to the documentation of flock(), "Locks are on
9301 files, not file descriptors. That is, file descriptors duplicated
9302 through dup(2) or fork(2) do not result in multiple instances of a lock,
9303 but rather multiple references to a single lock. If a process holding a
9304 lock on a file forks and the child explicitly unlocks the file, the
9305 parent will lose its lock.". To overcome this we have to make sure the
9306 RewriteLock file is opened _AFTER_ the childs were spawned which is now
9307 the case by opening it in the child_init instead of the module_init API
9308 hook. [Ralf S. Engelschall] PR#1029
9310 *) Change to Location and LocationMatch semantics. LocationMatch no
9311 longer lets a single slash match multiple adjacent slashes in the
9312 URL. This change is for consistency with RewriteRule and
9313 AliasMatch. Multiple slashes have meaning in URLs that they do
9314 not have in (some) filesystems. Location on the other hand can
9315 be considered a shorthand for a more complicated regex, and it
9316 does match multiple slashes with a single slash -- which is
9317 also consistent with the Alias directive.

9320 *) Fix bug with mod_mime_magic causing certain files, including files
9321 of length 0, to result in no response from the server.
9324 *) The Configure script now generates src/include/ap_config.h which
9325 contains the set of defines used when Apache is compiled on a platform.
9326 This file can then be included by external modules before including
9327 any Apache header files in case they are being built separately from
9328 Apache. Along with this change, a couple of minor changes were
9329 made to make Apache's #defines coexist peacefully with any autoconf
9330 defines an external module might have. [Rasmus Lerdorf]
9332 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9333 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9334 chance by the API to initialize its per-server configuration and thus
9335 receives the wrong one from the main server. This is now avoided by
9336 remembering the server together with the config structure while
9337 configuring and later assuming there is no config when we see a
9338 difference between the remembered server and the one calling us.
9339 [Ralf S. Engelschall] PR#1790
9341 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9342 is automatically disabled under configure time when the dbm_xxx functions
9343 are not available. Second, two heavy source code errors in the DBM
9344 support code were fixed. This makes DBM RewriteMap's usable again after
9345 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9347 *) Now all configuration files support Unix-style line-continuation via
9348 the trailing backslash ("\") character. This enables us to write down
9349 complex or just very long directives in a more readable way. The
9350 backslash character has to be really the last character before the
9351 newline and it has not been prefixed by another (escaping) backslash.

9357 *) To deal with modules being compiled and [dynamically] linked
9358 at a different time from the core, the SERVER_VERSION and
9359 SERVER_BUILT symbols have been abstracted through the new
9360 API routines apapi_get_server_version() and apapi_get_server_built().
9363 *) WIN32: Preserve trailing slash in canonical path (and hence
9364 in PATH_INFO). [Paul Sutton, Ben Laurie]
9366 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
9367 depending on the rev of Solaris and what mixture of modules
9368 are in use. So it has been disabled, and Solaris is back to
9369 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9370 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9371 up static content only servers. Or it may fail unpredictably.

9374 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9377 *) API: Rewrite of absoluteURI handling, and in particular how
9378 absoluteURIs match vhosts. Unless a request is a proxy request, a
9379 "http://host" url is treated as if a similar "Host:" header had been
9380 supplied. This change was made to support future HTTP/1.x protocols
9381 which may require clients to send absoluteURIs for all requests.
9383 In order to achieve this change subtle changes were made to the API. In a
9384 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9385 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9386 by the core, modules must set it during the post_read_request or
9387 translate_names phase.
9389 Plus changes to the virtualhost test suite for absoluteURI testing.
9391 This fixes several bugs with the proxy proxying requests to vhosts
9392 managed by the same httpd.
9395 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
9396 code from mod_rewrite. The vhost matching is now performed by a
9397 globally available function matches_request_vhost(). [Dean Gaudet]

9410 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
9411 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
9413 *) API: A new source module main/util_uri.c; It contains a routine
9414 parse_uri_components() and friends which breaks a URI into its component
9415 parts. These parts are stored in a uri_components structure called
9416 parsed_uri within each request_rec, and are available to all modules.
9417 Additionally, an unparse routine is supplied which re-assembles the URI
9418 components back to an URI, optionally hiding the username:password@ part
9419 from ftp proxy requests, and other useful routines. Within the structure,
9420 you find on a ready-for-use basis:
9421 scheme; /* scheme ("http"/"ftp"/...) */
9422 hostinfo; /* combined [user[:password]@]host[:port] */
9423 user; /* user name, as in http://user:passwd@host:port/ */
9424 password; /* password, as in http://user:passwd@host:port/ */
9425 hostname; /* hostname from URI (or from Host: header) */
9426 port_str; /* port string (integer representation is in "port") */
9427 path; /* the request path (or "/" if only scheme://host was given) */
9428 query; /* Everything after a '?' in the path, if present */
9429 fragment; /* Trailing "#fragment" string, if present */
9430 This is meant to serve as the platform for *BIG* savings in
9431 code complexity for the proxy module (and maybe the vhost logic).
9434 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
9435 ${map:key}) available for all location where a string is created in
9436 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
9437 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
9438 possible expansions are consequently usable at all string creation
9439 locations. [Ralf S. Engelschall]
9441 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
9442 and not 1) and the per-virtual-server merging of directives. Now all
9443 directives except `RewriteEngine' and `RewriteOption' are either
9444 completely overridden (default) or completely inherited (when
9445 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

9454 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
9455 (like SunOS and FreeBSD) which don't accept the locking of pipes
9456 directly. A new directive RewriteLock is introduced which can be used to
9457 setup a separate locking file which then is used for synchronization.

9475 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
9476 type but with a special post-processing for the looked-up value: It
9477 parses it into alternatives according to `|' chars and then only one
9478 particular alternative is chosen randomly (this is an essential
9479 functionality needed for balancing between backend-servers when using
9480 Apache as a Reverse Proxy. The looked up value here is a list of
9481 servers). Second, `int' with the built-in maps named `tolower' and
9482 `toupper' which can be used to map URL parts to a fixed case (this is an
9483 essential feature to fix the case of server names when doing mass
9484 virtual-hosting with the help of mod_rewrite instead of using
9485 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
9486 Jay Soffian <jay@cimedia.com>] PR#1631
9488 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
9489 This directive lets Apache adjust the URL in Location-headers on HTTP
9490 redirect responses sent by the remote server. This way the virtually
9491 mapped area is no longer left on redirects and thus by-passed which is
9492 especially essential when running Apache as a reverse proxy.

9642 references in Makefiles have been changed to the simpler -Iinclude

9681 *) API: table_add, table_merge, and table_set include implicit pstrdup()
9682 of the key and value. But in many cases this is not required
9683 because the key/value is a constant, or the value has been built
9684 by pstrcat() or other similar means. New routines table_addn,
9685 table_mergen, and table_setn have been added to the API, these
9686 routines do not pstrdup() their arguments. The core code and
9687 standard modules were changed to take advantage of these routines.
9688 The resulting server is up to 20% faster in some situations.
9690 Note that it is easy to get code subtly wrong if you pass a key/value
9691 which is in a pool other than the pool of the table. The only
9692 safe thing to do is to pass key/values which are in the pool of
9693 the table, or in one of the ancestors of the pool of the table.
9694 i.e. if the table is part of a subrequest, a value from the main
9695 request's pool is OK since the subrequest pool is a sub_pool of the
9696 main request's pool (and therefore has a lifespan at most as long as
9697 the main pool). There is debugging code which can detect improper
9698 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.

9702 which don't exist on disk more gracefully; handles vhosts properly.
9703 Update documentation to reflect the code -- if there's no
9704 MimeMagicFile directive then the module is not enabled.
9707 *) PORT: Some older *nix dialects cannot automatically start scripts
9708 which begin with a #! interpreter line (the shell starts the scripts
9709 appropriately on these platforms). Apache now supports starting of
9710 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
9711 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
9714 *) API: "typedef array_header table" removed from alloc.h, folks should
9715 have been writing to use table as if it were an opaque type, but even
9716 some standard modules got this wrong. By changing the definition
9717 to "typedef struct table table" module authors will receive compile
9718 time warnings that they're doing the wrong thing. This change
9719 facilitates future changes with more sophisticated table
9720 structures. Specifically, module authors should be using table_elts()
9721 to get access to an array_header * for the table. [Dean Gaudet]
9723 *) API: Renamed new_connection() to avoid namespace collision with LDAP
9724 library routines. [Ken Coar, Rasmus Lerdorf]
9726 *) WIN32: mod_speling is now available on the Win32 platform.
9729 *) For clarity the following compile time definition was changed:
9731 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
9733 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
9734 and not be a general notice that the OS has mmap(). Now the
9735 HAVE_MMAP/SHMGET #defines strictly are informational that the
9736 OS has that method of shared memory; the type to use for
9737 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
9738 and USE_SHMGET_SCOREBOARD). This allows outside modules to
9739 determine if shared memory is available and allows Apache
9740 to determine the best method to use for the scoreboard.
9743 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
9744 as do various earlier versions. It should be safe on all versions.
9745 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
9746 the slack code. A few other cleanups for Unixware.
9747 [Tom Hughes <thh@cyberscience.com>] PR#1082, PR#1282, PR#1499, PR#1553
9749 *) PORT: A/UX can handle single-listen accepts without mutex
9750 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
9752 *) When die() happens we need to eat any request body if one exists.
9753 Otherwise we can't continue with a keepalive session. This shows up
9754 as a POST problem with MSIE 4.0, typically against pages which are
9755 authenticated. [Roy Fielding] PR#1399
9757 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
9758 header will be passed to CGIs. This is generally a security hole, so
9759 it's not a default. [Marc Slemko] PR#549
9761 *) Fix Y2K problem with date printing in suexec log.
9762 [Paul Eggert <eggert@twinsun.com>] PR#1343
9764 *) WIN32 deserves a pid file. [Ben Hyde]
9766 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
9768 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
9769 The choice of flock vs. fcntl was made based on timings which showed that
9770 even on non-NFS, non-exported filesystems fcntl() was an order of
9771 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
9772 that single socket users will see no difference. [Dean Gaudet] PR#467
9774 *) "File does not exist" error message was erroneously including the
9775 errno. [Marc Slemko]
9777 *) Improve the warning message generated when a client drops the
9778 connection (hits stop button, etc.) during a send. [Roy Fielding]
9780 *) Defining GPROF will disable profiling in the parent and enable it
9781 in the children. If you're profiling under Linux this is pretty much
9782 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
9784 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
9787 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
9788 gcc functionality. Work around it.
9789 [Keith Severson <keith@sssd.navy.mil>] PR#1613
9791 *) Some linkers complain when .o files contain no functions.
9792 [Keith Severson <keith@sssd.navy.mil>] PR#1614
9794 *) Some const declarations in mod_imap.c that were added for debugging
9795 purposes caused some compilers heartburn without adding any
9796 significant value, so they've been removed. [Ken Coar]
9798 *) The src/main/*.h header files have had #ifndef wrappers added to
9799 insulate them against duplicate calls if they get included through
9800 multiple paths (e.g., in .c files as well as other .h files).
9803 *) The libap routines now have a header file for their prototypes,
9804 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
9806 *) mod_autoindex with a plaintext header file would emit the <PRE>
9807 start-tag before the HTML preamble, rather than after the preamble
9808 but before the header file contents. [John Van Essen <jve@gamers.org>]
9811 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
9812 only an issue on systems without a MAXDNAME define or where
9813 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
9815 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
9816 is used to read various types of files such as htaccess and
9817 htpasswd files. [Marc Slemko]
9819 *) SECURITY: Ensure that the buffer returned by ht_time is always
9820 properly null terminated. [Marc Slemko]
9822 *) The "Connection" header could be sent back with multiple "close"
9823 tokens. Not an error, but a waste.
9824 [Ronald.Tschalaer@psi.ch] PR#1683
9826 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
9827 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
9829 *) "basic" auth needs a case-insensitive comparison.
9830 [Ronald.Tschalaer@psi.ch] PR#1666
9832 *) For maximum portability, the environment passed to CGIs should
9833 only contain variables whose names match the regex
9834 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
9835 underscores over any character outside the regex. This
9836 affects HTTP_* variables, in a way that should be backward
9837 compatible for all the standard headers; and affects variables
9838 set with SetEnv/BrowserMatch and similar directives.
9841 *) mod_speling returned incorrect HREF's when an ambigous match
9842 was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)
9843 [robinton@amtrash.comlink.de (Soeren Ziehe), Martin Kraemer]
9845 *) PORT: Apache now compiles & runs on an EBCDIC mainframe
9846 (the Siemens BS2000/OSD family) in the POSIX subsystem
9849 *) PORT: Fix problem killing children when terminating. Allow ^C
9850 to shut down the server. [Brian Havard]
9852 *) pstrdup() is implicit in calls to table_* functions, so there's
9853 no need to do it before calling. Clean up a few cases.
9854 [Marc Slemko, Dean Gaudet]
9856 *) new -C and -c command line arguments
9858 -C "directive" : process directive before reading config files
9859 -c "directive" : process directive after reading config files
9861 httpd -C "PerlModule Apache::httpd_conf"
9862 [Doug MacEachern, Martin Kraemer]
9864 *) WIN32: Fix the execution of CGIs that are scripts and called
9865 with path info that does not have an '=' in.
9866 (eg. http://server/cgi-bin/printenv?foobar)
9867 [Marc Slemko] PR#1591
9869 *) WIN32: Fix a call to os_canonical_filename so it doesn't try to
9870 mess with fake filenames. This fixes proxy caching on
9873 *) SECURITY: General mod_include cleanup, including fixing several
9874 possible buffer overflows and a possible infinite loop.
9875 [Dean Gaudet, Marc Slemko]
9877 *) SECURITY: Numerous changes to mod_imap in a general cleanup
9878 including fixing a possible buffer overflow. [Dean Gaudet]
9880 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
9881 (connections are not dropped). Code can handle graceful restarts
9882 (but there is as yet no way to signal this to Apache). Various
9883 other cleanups. [Paul Sutton]
9885 *) The aplog_error changes specific to 1.3 introduced a buffer
9886 overrun in the (now legacy) log_printf function. Fixed.
9889 *) mod_digest didn't properly deal with proxy authentication. It
9890 also lacked a case-insensitive comparision of the "Digest"
9891 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
9893 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
9895 *) A few cleanups in mod_info to make it thread-safe, and remove an
9896 off-by-5 bug that could hammer \0 on the stack. [Dean Gaudet]
9898 *) no2slash() was O(n^2) in the length of the input. Make it O(n).
9901 *) API: migration from strncpy() to our "enhanced" version called
9902 ap_cpystrn() for performance and functionality reasons.
9903 Located in libap.a. [Jim Jagielski]
9905 *) table_set() and table_unset() did not deal correctly with
9906 multiple occurrences of the same key.

9909 *) The AuthName must now be enclosed in quotes if it is to contain

9915 versions. [Ben Laurie] PR#1533
9917 *) PORT: Update the MPE port [Mark Bixby, Jim Jagielski]
9919 *) Interim (slow) fix for p->sub_pool critical sections in
9920 alloc.c (affects win32 only). [Ben Hyde]
9922 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
9924 *) send_fd_length() did not calculate total_bytes_sent properly.
9925 [Ben Reser <breser@regnow.com>] PR#1366
9927 *) The bputc() macro was not properly integrated with the chunking
9928 code; in many cases modules using bputc() could cause completely
9929 bogus chunked output. (Typically this will show up as problems
9930 with Internet Explorer 4.0 reading a page, but other browsers
9931 having no problem.) [Dean Gaudet]
9933 *) Create LARGE_WRITE_THRESHOLD define which determines how many
9934 bytes have to be supplied to bwrite() before it will consider
9935 doing a writev() to assemble multiple buffers in one system
9936 call. This is critical for modules such as mod_include,
9937 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
9938 strings in some cases. The result would be extra effort
9939 setting up writev(), and in many cases extra effort building
9940 chunks. The default is 31, it can be overriden at compile
9943 *) Move the gid switching code into the child so that log files
9944 and pid files are opened with the root gid.
9945 [Gregory A Lundberg <lundberg@vr.net>]

9948 instead of counting control characters.
9949 [Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340
9951 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
9952 so the functionality is available to applications other than the
9953 server itself (like the src/support tools). [Ken Coar]
9955 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
9956 the libap consolidation work. [Ken Coar]
9958 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
9959 useful, and isn't what the standards require. Now it returns 0
9960 and writes nothing. [Dean Gaudet]
9962 *) When an error occurs in fcntl() locking suggest the user look up
9963 the docs for LockFile. [Dean Gaudet]
9965 *) Eliminate some dead code from writev_it_all().

9968 *) mod_autoindex had an fread() without checking the result code.
9969 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"

9972 *) It appears the "257th byte" bug (see

10050 This turns out to be a bug in Winsock - select() doesn't always
10051 return the correct status. [Ben Laurie]
10053 *) Directives owned by http_core can now use the new check_cmd_context()
10054 routine to ensure that they're not being used within a container
10055 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
10057 *) PORT: Recent changes made it necessary to add explicit prototype
10058 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
10060 *) It was necessary to distinguish between resources which are
10061 allocated in the parent, for cleanup in the parent, and resources
10062 which are allocated in each child, for cleanup in each child.
10063 A new pool was created which is passed to the module child_init
10064 and child_exit functions; modules are free to register per-child
10065 cleanups there. This fixes a bug with reliable piped logs.
10068 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
10069 unless it was also doing FancyIndexes, but it displayed the
10070 HeaderName file at the top under all circumstances. It now shows
10071 the ReadmeName file for simple indices, too, as it should.
10074 *) http_core was mmap()ing even in cases where it wasn't going to
10075 read the file. [Ben Hyde <bhyde@gensym.com>]
10077 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
10078 Now the rewriting engine (the heart of mod_rewrite) is organized more
10079 straight-forward, first time well documented and reduced to the really
10080 essential parts. All redundant cases were stripped off and processing now
10081 is the same for both per-server and per-directory context with only a
10082 minimum difference (the prefix stripping in per-dir context). As a
10083 side-effect some subtle restrictions and two recently discovered problems
10084 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
10085 context and restrictions on the substitution URL on redirects.
10086 Additionally some minor source cleanups were done.

10222 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
10223 use USE_SHMGET_SCOREBOARD.
10226 *) Various improvements in detecting config file errors (missing closing
10227 directives for <Directory>, <Files> etc. blocks, prohibiting global
10228 server settings in <VirtualHost> blocks, flagging unhandled multiple
10229 arguments to <Directory>, <Files> etc.)
10232 *) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
10233 variable to provide this one to suexec'd CGIs, too.
10234 [M.D.Parker <mdpc@netcom.com>] PR#1284
10236 *) New support tool: src/support/split-logfile, a sample Perl script which
10237 splits up a combined access log into separate files based on the
10238 name of the virtual host (listed first in the log records by "%v").
10241 Changes with Apache 1.3b2 (there is no 1.3b1)
10243 *) TestCompile was not passing $LIBS [Dean Gaudet]
10245 *) Makefile.tmpl was not using $CFLAGS in the link phase.
10248 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
10249 rudimentary memory debugger which can be used on live servers with
10250 low impact -- it sets all allocated and freed memory bytes to 0xa5.
10251 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
10252 and free() for each object. This is far more expensive and should
10253 only be used for testing with tools such as Electric Fence and
10254 Purify. See main/alloc.c for more details. [Dean Gaudet]
10256 *) Configure uses a sh trap and didn't set its exitcode properly.
10257 [Dean Gaudet] PR#1159
10259 *) Yet another vhost revamp. Add the NameVirtualHost directive which
10260 explicitly lists the ip:port pairs that are to be used for name-vhosts.
10261 From a given ip:port, regardless what the Host: header is, you can
10262 only reach the vhosts defined on that ip:port. The precedence of
10263 vhosts was reversed to match other precedences in the config --
10264 the earlier vhosts override the later vhosts. All vhost matching was
10265 moved into http_vhost.[ch]. [Dean Gaudet]
10267 *) ap_inline can be used to force inlining. GNUC __attribute__() can
10268 be used for whatever reason is appropriate (i.e. format() warnings
10269 for printf style functions). Both are enabled only with
10270 gcc >= 2.7.x (so that we have fewer support issues with older
10271 versions). [Dean Gaudet]
10273 *) Fix support for Proxy Authentication (we were testing the response
10274 status too early). [Marc Slemko]
10276 *) CoreDumpDirectory directive directs where the core file is
10277 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
10278 received. [Marc Slemko, Dean Gaudet]
10280 *) PORT: Support for Atari MINT.
10281 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
10283 *) When booting, apache will now detach itself from stdin, stdout,
10284 and stderr. stderr will not be detached until after the config
10285 files have been read so you will be able to see initial error
10286 messages. After that all errors are logged in the error_log.
10287 This makes it more convenient to start apache via rsh, ssh,
10288 or crontabs. [Dean Gaudet] PR#523
10290 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10291 Also removed the auto-generated link to www.apache.org that was the
10292 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10294 *) send_fb would not detect aborted connections in some situations.
10297 *) mod_include would use uninitialized data when parsing certain
10298 expressions involving && and ||. [Brian Slesinsky] PR#1139
10300 *) mod_imap should only handle GET methods. [Jay Bloodworth]
10302 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10304 *) mod_autoindex improperly counted &escapes; as more than one
10305 character in the description. It also improperly truncated
10306 descriptions that were exactly the maximum length.
10309 *) RedirectMatch was not properly escaping the result (PR#1155). Also
10310 "RedirectMatch /advertiser/(.*) $1" is now permitted.
10313 *) mod_include now uses symbolic names to check for request success
10314 and return HTTP errors, and correctly handles all types of
10315 redirections (previously it only did temporary redirect correctly).
10316 [Ken Coar, Roy Fielding]
10318 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10319 r->filename. Since those two are meant to be in sync with each other
10320 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
10322 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
10323 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
10325 *) Inetd mode (which is buggy) uses timeouts without having setup the
10326 jmpbuffer. [Dean Gaudet] PR#1064
10328 *) Work around problem under Linux where a child will start looping
10329 reporting a select error over and over.
10330 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
10332 *) Fixed error in proxy_util.c when looping through multiple host IP
10333 addresses. [Lars Eilebrecht] PR#974
10335 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10336 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10337 bytes before writing, but it will never split a log entry across a
10338 buffer boundary. [Dean Gaudet]
10340 *) API: the short_score record has been split into two pieces, one which
10341 the parent writes on, and one which the child writes on. As part of
10342 this change the get_scoreboard_info() function was removed, and
10343 scoreboard_image was exported. This change fixes a race condition
10344 in file based scoreboard systems, and speeds up changes involving the
10345 scoreboard in earlier 1.3 development. [Dean Gaudet]
10347 *) API: New register_other_child() API (see http_main.h) which allows
10348 modules to register children with the parent for maintenance. It
10349 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10351 *) API: New piped_log API (see http_log.h) which implements piped logs,
10352 and will use register_other_child to implement reliable piped logs
10353 when it is available. The reliable piped logs part can be disabled
10354 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10355 logs is only available on Unix. [Dean Gaudet]
10357 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10358 meets_conditions(). This allows conditional HTTP selection to be
10359 handled separately from the storing of the header fields, and provides
10360 the ability for CGIs to set their own ETags for conditional checking.
10361 [Ken Coar, Roy Fielding] PR#895
10363 *) Changes to mod_log_config to allow naming of format strings.
10364 Format nicknames are defined with "LogFormat fmt nickname", and can
10365 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
10368 *) New module, "mod_speling", which can help find files even when
10369 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
10371 *) API: New function child_terminate() triggers the child process to
10372 exit, while allowing the child finish what it needs to for the
10373 current request first.
10374 [Doug MacEachern, Alexei Kosut]
10376 *) Windows now defaults to using full status reports with mod_status.
10377 [Alexei Kosut] PR #1094
10379 *) *Really* disable all mod_rewrite operations if the engine is off.
10380 Some things (like RewriteMaps) were checked/performed even if they
10381 weren't supposed to be. [Ken Coar] PR #991
10383 *) Implement a new timer scheme which eliminates the need to call alarm() all
10384 the time. Instead a counter in the scoreboard for each child is used to
10385 show when the child has made forward progress. The parent samples this
10386 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10387 progress has been made in the timeout period. This reduces the static
10388 request best-case syscall count to 22 from 29. This scheme is only
10389 used by systems with memory-based scoreboards. [Dean Gaudet]
10391 *) The proxy now properly handles CONNECT requests which are sent
10392 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10394 *) A script called apachectl has been added to the support
10395 directory. This script allows you to do things such as
10396 "apachectl start" and "apachectl restart" from the command
10397 line. [Marc Slemko]
10399 *) Modules and core routines are now put into libraries, which
10400 simplifies the link line tremendously (among other advantages).
10403 *) Some of the MD5 names defined in Apache have been renamed to have
10404 an `ap_' prefix to avoid conflicts with routines supplied by
10405 external libraries. [Ken Coar]
10407 *) Removal of mod_auth_msql.c from the distribution. There are many
10408 other options for databases today. Rather than offer one option,
10409 offer none at this time. mod_auth_msql and other SQL database
10410 authentication modules can be found at the Apache Module Registry.
10411 http://modules.apache.org/ It would be nice to offer a generic
10412 mod_auth_sql option in the near future.
10414 *) PORT: BeOS support added [Alexei Kosut]
10416 *) Configure no longer accepts the -make option, since it creates
10417 Makefile on the fly based on Makefile.tmpl and Configuration.
10419 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
10420 of forcibly killing off all its processes and exiting without
10421 cleaning up. [Alexei Kosut]
10423 *) API: A new field in the request_rec, r->mtime, has been added to
10424 avoid gratuitous parsing of date strings. It is intended to hold
10425 the last-modified date of the resource (if applicable). An
10426 update_mtime() routine has also been added to advance it if
10427 appropriate. [Roy Fielding, Ken Coar]
10429 *) SECURITY: If a htaccess file can not be read due to bad permissions,
10430 deny access to the directory with a HTTP_FORBIDDEN. The previous
10431 behavior was to ignore the htaccess file if it could not be read.
10432 This change may make some setups with unreadable htaccess files
10433 stop working. [Marc Slemko] PR#817
10435 *) Add aplog_error() providing a mechanism to define levels of
10436 verbosity to the server error logging. This addition also provides
10437 the ability to log errors using syslogd. Error logging is configurable
10438 on a per-server basis using the LogLevel directive. Conversion
10439 of log_*() in progress. [Randy Terbush]
10441 *) Further enhance aplog_error() to not log filename, line number, and
10442 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
10444 *) WIN32: Canonicalise filenames under Win32. Short filenames are
10445 converted to long ones. Backslashes are converted to forward
10446 slashes. Case is converted to lower. Parts of URLs that do not
10447 correspond to files are left completely alone. [Ben Laurie]
10449 *) PORT: 2 new OSs added to the list of ports:
10450 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
10451 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
10453 *) Add the server version (SERVER_VERSION macro) to the "server
10454 configured and running" entry in the error_log. Also build an
10455 object file at link-time that contains the current time
10456 (SERVER_BUILT global const char[]), and include that in the
10457 message. [Ken Coar]
10459 *) Set r->headers_out when sending responses from the proxy.
10460 This fixes things such as the logging of headers sent from
10461 the proxy. [Marc Slemko] PR#659
10463 *) support/httpd_monitor is no longer distributed because the
10464 scoreboard should not be file based if at all possible. Use
10465 mod_status to see current server snapshot.
10467 *) (set_file_slot): New function, allowing auth directives to be
10468 independent of the server root, so the server documents can be
10469 moved to a different directory or machine more easily.
10470 [David J. MacKenzie]
10472 *) If no TransferLog is given explicitly, decline
10473 to log. This supports coexistence with other logging modules,
10474 such as the custom one that UUNET uses. [David J. MacKenzie]
10476 *) Check for titles in server-parsed HTML files.
10477 Ignore leading newlines and returns in titles. The old behavior
10478 of replacing a newline after <title> with a space causes the
10479 title to be misaligned in the listing. [David J. MacKenzie]
10481 *) Change mod_cern_meta to be configurable on a per-directory basis.
10482 [David J. MacKenzie]
10484 *) Add 'Include' directive to allow inclusion of configuration
10485 files within configuration files. [Randy Terbush]
10487 *) Proxy errors on connect() are logged to the error_log (nothing
10488 new); now they include the IP address and port that failed
10489 (*that's* new). [Ken Coar, Marc Slemko] PR#352
10491 *) Various architectures now define USE_MMAP_FILES which causes
10492 the server to use mmap() for static files. There are two
10493 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
10494 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
10495 number of bytes written in one cycle from a single mmap()d object,
10496 default 32768). [Dean Gaudet]
10498 *) API: Added post_read_request API phase which is run right after reading
10499 the request from a client, or right after an internal redirect. It is
10500 useful for modules setting environment variables that depend only on
10501 the headers/contents of the request. It does not run during subrequests
10502 because subrequests inherit pretty much everything from the main
10503 request. [Dean Gaudet]
10505 *) Added mod_unique_id which is used to generate a unique identifier for
10506 each hit, available in the environment variable UNIQUE_ID.
10509 *) init_modules is now called after the error logs have been opened. This
10510 allows modules to emit information messages into the error logs.
10513 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10514 information for case where proxy module is not available. [Marc Slemko]
10516 *) PORT: Apache has need for mutexes to serialize its children around
10517 accept. In prior versions either fcntl file locking or flock file
10518 locking were used. The method is chosen by the definition of
10519 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
10520 and FLOCK for flock(). New options have been added:
10521 - SYSVSEM to use System V style semaphores
10522 - PTHREAD to use POSIX threads (appears to work on Solaris only)
10523 - USLOCK to use IRIX uslock
10524 Based on timing various techniques, the following changes were made
10526 - Linux 2.x uses flock instead of fcntl
10527 - Solaris 2.x uses pthreads
10528 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
10529 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
10530 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
10531 Martijn Koster <m.koster@pobox.com>]
10533 *) PORT: The semantics of accept/select make it very desirable to use
10534 mutexes to serialize accept when multiple Listens are in use. But
10535 in the case where only a single socket is open it is sometimes
10536 redundant to serialize accept(). Not all unixes do a good job with
10537 potentially dozens of children blocked on accept() on the same
10538 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
10539 the server will avoid serialization when listening on only one socket,
10540 and use serialization when listening on multiple sockets.
10541 [Dean Gaudet] PR#467
10543 *) Configure changes: TestLib replaced by TestCompile, which has
10544 some additional capability (such as doing a sanity check of
10545 the compiler and flags selected); the version of Solaris is now
10546 available via the #define value of SOLARIS2; IRIX n32bit libs
10547 now supported and selectable by new Configuration Rule: IRIXN32;
10548 We no longer default to -O2 optimization. [Jim Jagielski]
10550 *) Updated Configure: Configuration now uses AddModule to specify
10551 module source or binary file location, relative to src directory.
10552 Modules can be dropped into modules/extra, or in their own
10553 directory, and modules can come with a Makefile or Configure can
10554 create one. Modules can add compiler or library information to
10555 generated Makefiles. [Paul Sutton]
10557 *) Source core re-organisation: distributed modules are now in
10558 modules/standard. All other source code is in main. OS-specific
10559 code is in os/{unix,emx,win32} directories. [Paul Sutton]
10561 *) mod_browser has been removed, since it's replaced by mod_setenvif.
10564 *) Fix another long-standing bug in sub_req_lookup_file where it would
10565 happily skip past access checks on subdirectories looked up with
10566 relative paths. (It's used by mod_dir, mod_negotiation,
10567 and mod_include.) [Dean Gaudet]
10569 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
10570 N is the number of <Directory> sections, and M is the number of
10571 components in the filename of an object.
10573 To achieve this optimization the following config changes were made:
10574 - Wildcards (* and ?, not the regex forms) in <Directory>s,
10575 <Files>s, and <Location>s now treat a slash as a special
10576 character. For example "/home/*/public_html" previously would
10577 match "/home/a/andrew/public_html", now it only matches things
10578 like "/home/bob/public_html". This mimics /bin/sh behaviour.
10579 - It's possible now to use [] wildcarding in <Directory>, <Files>
10581 - Regex <Directory>s are applied after all non-regex <Directory>s.
10585 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
10586 and corrupted paths. [Dean Gaudet]
10588 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
10589 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
10590 be accessed now via backreferences $1..$9 in RewriteConds test-against
10591 strings in addition to RewriteRules subst string. Second the grouped
10592 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
10593 via backreferences %1..%9 both in following RewriteCond test-against
10594 strings and RewriteRules subst string. This provides maximum flexibility
10595 through the use of backreferences.
10596 Additionally the rewriting engine was cleaned up by putting common
10597 code to the new expand_backrefs_inbuffer() function.
10598 [Ralf S. Engelschall]
10600 *) When merging the main server's <Directory> and <Location> sections into
10601 a vhost, put the main server's first and the vhost's second. Otherwise
10602 the vhost can't override the main server. [Dean Gaudet] PR#717
10604 *) The <Directory> code would merge and re-merge the same section after
10605 a match was found, possibly causing problems with some modules.
10608 *) ip-based vhosts are stored and queried using a hashing function, which
10609 has been shown to improve performance on servers with many ip-vhosts.
10610 Some other changes had to be made to accommodate this:
10611 - the * address for vhosts now behaves like _default_
10612 - the matching process now is:
10613 - match an ip-vhost directly via hash (possibly matches main
10615 - if that fails, just pretend it matched the main server
10616 - if so far only the main server has been matched, perform
10617 name-based lookups (ServerName, ServerAlias, ServerPath)
10618 *only on name-based vhosts*
10619 - if they fail, look for _default_ vhosts
10620 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
10622 *) dbmmanage overhaul:
10623 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
10624 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
10625 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
10626 - provide better seed for rand
10627 - prompt for password as per getpass(3) (turn off echo, read from
10629 - use "newstyle" crypt based on $Config{osname} ($^O)
10630 - will not add a user if already in database, use new `update' command
10632 - added `check' command to check a users' password
10633 - added `import' command to convert existing password text-files or
10634 dbm files exported with `view'
10635 - more descriptive usage, general cleanup, 'use strict' clean, etc.
10638 *) Added psocket() which is a pool form of socket(), various places within
10639 the proxy weren't properly blocking alarms while registering the cleanup
10640 for its sockets. bclose() now uses pclose() and pclosesocket(). There
10641 was a bug where the client socket was being close()d twice due a still
10642 registered cleanup. [Dean Gaudet]
10644 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
10647 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
10648 [Jason Venner <jason@idiom.com>] PR#667
10650 *) Enable ``=""'' for RewriteCond directives to match against
10651 the empty string. This is the preferred way instead of ``^$''.
10652 [Ralf S. Engelschall]
10654 *) Fixed an infinite loop in mod_imap for references above the server root
10655 [Dean Gaudet] PR#748
10657 *) mod_proxy now has a ReceiveBufferSize directive, similar to
10658 SendBufferSize, so that the TCP window can be set appropriately
10659 for LFNs. [Phillip A. Prindeville]
10661 *) mod_browser has been replaced by the more general mod_setenvif
10662 (courtesy of Paul Sutton). BrowserMatch* directives are still
10663 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
10664 UnSetEnvIfZero directives. [Ken Coar]
10666 *) "HostnameLookups double" forces double-reverse DNS to succeed in
10667 order for remote_host to be set (for logging, or for the env var
10668 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
10671 *) mod_access overhaul:
10672 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
10673 and cidr syntax (i.e. 10.1.0.0/16). PR#762
10674 - Critical path was sped up by pre-computing a few things at config time.
10675 - The undocumented syntax "allow user-agents" was removed,
10676 the replacement is "allow from env=foobar" combined with mod_browser.
10677 - When used with hostnames it now forces a double-reverse lookup
10678 no matter what the directory settings are. This double-reverse
10679 doesn't affect any of the other routines that use the remote
10680 hostname. In particular it's still passed to CGIs and the log
10681 without the double-reverse check. Related PR#860.
10684 *) When a large bwrite() occurs (larger than the internal buffer size),
10685 while there is already something in the buffer, apache will combine
10686 the large write and the buffer into a single writev(). (This is
10687 in anticipation of using mmap() for reading files.)
10690 *) In obscure cases where a partial socket write occurred while chunking,
10691 Apache would omit the chunk header/footer on the next block. Cleaned
10692 up other bugs/inconsistencies in error conditions in buff.c. Fixed
10693 a bug where a long pause in DNS lookups could cause the last packet
10694 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
10696 *) API: Added child_exit function to module structure. This is called
10697 once per "heavy-weight process" just before a server child exit()'s
10698 e.g. when max_requests_per_child is reached, etc.
10699 [Doug MacEachern, Dean Gaudet]
10701 *) mod_include cleanup showed that handle_else was being used to handle
10702 endif. It didn't cause problems, but it was cleaned up too.
10705 *) mod_cern_meta would attempt to find meta files for the directory itself
10706 in some cases, but not in others. It now avoids it in all cases.
10709 *) mod_mime_magic would core dump if there was a decompression error.
10710 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
10712 *) PORT: some variants of DGUX require -lsocket -lnsl
10713 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
10715 *) mod_autoindex now allows sorting of FancyIndexed directory listings
10716 by the various fields (name, size, et cetera), either in ascending
10717 or descending order. Just click on the column header. [Ken Coar]
10719 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
10720 CPUs like the Alpha. Apache still stores ints in pointers, but that's
10721 the relatively safe direction. [Dean Gaudet] PR#344
10723 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
10724 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
10726 *) child_main avoids an unneeded call to select() when there is only one
10727 listening socket. [Dean Gaudet]
10729 *) In the event that the server is starved for idle servers it will
10730 spawn 1, then 2, then 4, ..., then 32 servers each second,
10731 doubling each second. It'll also give a warning in the errorlog
10732 since the most common reason for this is a poor StartServers
10733 setting. The define MAX_SPAWN_RATE can be used to raise/lower
10734 the maximum. [Dean Gaudet]
10736 *) Apache now provides an effectively unbuffered connection for
10737 CGI scripts. This means that data will be sent to the client
10738 as soon as the CGI pauses or stops output; previously, Apache would
10739 buffer the output up to a fixed buffer size before sending, which
10740 could result in the user viewing an empty page until the CGI finished
10741 or output a complete buffer. It is no longer necessary to use an
10742 "nph-" CGI to get unbuffered output. Given that most CGIs are written
10743 in a language that by default does buffering (e.g. perl) this
10744 shouldn't have a detrimental effect on performance.
10746 "nph-" CGIs, which formerly provided a direct socket to the client
10747 without any server post-processing, were not fully compatible with
10748 HTTP/1.1 or SSL support. As such they would have had to implement
10749 the transport details, such as encryption or chunking, in order
10750 to work properly in certain situations. Now, the only difference
10751 between nph and non-nph scripts is "non-parsed headers".
10752 [Dean Gaudet, Sameer Parekh, Roy Fielding]
10754 *) If a BUFF is switched from buffered to unbuffered reading the first
10755 bread() will return whatever remained in the buffer prior to the
10756 switch. [Dean Gaudet]
10758 Changes with Apache 1.3a1
10760 *) Added another Configure helper script: TestLib. It determines
10761 if a specified library exists. [Jim Jagielski]
10763 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
10764 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
10767 *) PORT: Some architectures use size_t for various lengths in network
10768 functions such as accept(), and getsockname(). The definition
10769 NET_SIZE_T is used to control this. [Dean Gaudet]
10771 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
10772 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
10773 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
10775 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
10776 [Igor N Kovalenko <infoh@mail.wplus.net>]
10778 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
10779 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
10780 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
10781 [Dean Gaudet] related PR#875
10783 *) API: Correct child_init() slot declaration from int to void, to
10784 match the init() declaration. Update mod_example to use the new
10787 *) added transport handle slot (t_handle) to the BUFF structure
10790 *) get_client_block() returns wrong length if policy is
10791 REQUEST_CHUNKED_DECHUNK.
10792 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
10794 *) Support the image map format of FrontPage. For example:
10795 rect /url.hrm 10 20 30 40
10796 ["Chris O'Byrne" <obyrne@iol.ie>] PR#807
10798 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
10799 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
10801 *) AddModuleInfo directive for mod_info which allows you to annotate
10802 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
10804 *) Added NoProxy directive to avoid using ProxyRemote for selected
10805 addresses. Added ProxyDomain directive to cause unqualified
10806 names to be qualified by redirection.
10807 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
10809 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
10810 header to the remote host in the proxy. [Sameer Parekh and
10813 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
10814 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
10815 URLs, fixed rewritelog(), fixed forced response code handling on
10816 redirects from within .htaccess files, disabled pipe locking under
10817 braindead SunOS 4.1.x, allow env variables to be set even on rules with
10818 no substitution, bugfixed situations where HostnameLookups is off, made
10819 mod_rewrite more thread-safe for NT port and fixed problem when creating
10820 an empty query string via "xxx?".
10821 This update also removes the copyright of Ralf S. Engelschall,
10822 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
10823 exclusively copyrighted by the Apache Group now. This happened because
10824 the author now has gifted mod_rewrite exclusively to the Apache Group and
10825 no longer maintains an external version.
10826 [Ralf S. Engelschall]
10828 *) API: Added child_init function to module structure. This is called
10829 once per "heavy-weight process" before any requests are handled.
10830 See http_config.h for more details. [Dean Gaudet]
10832 *) Anonymous_LogEmail was logging on each subrequest.
10833 [Dean Gaudet] PR#421, 868
10835 *) API: Added is_initial_req() which tests if the request being
10836 processed is the initial request, or a subrequest.
10839 *) Extended SSI (mod_include) now handles additional relops for
10840 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
10842 *) Configure fixed to correctly propagate user-selected options and
10843 settings (such as CC and OPTIM) to Makefiles other than
10844 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
10846 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
10847 directory indices to start with the contents of the HeaderName file
10848 if there is one. If there isn't one, the behaviour is unchanged.
10849 [Ken Coar, Roy Fielding, Andrey A. Chernov]
10851 *) WIN32: Modules can now be dynamically loaded DLLs using the
10852 LoadModule/LoadFile directives. Note that module DLLs must be
10853 compiled with the multithreaded DLL version of the runtime library.
10854 [Alexei Kosut and Ben Laurie]
10856 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
10857 This allows the admin to completely remove automatic indexing
10858 from the server, while still supporting the basic functions of
10859 trailing-slash redirects and DirectoryIndex files. Note that if
10860 you're carrying over an old Configuration file and you use directory
10861 indexing then you'll want to add:
10863 Module autoindex_module mod_autoindex.o
10865 before mod_dir in your Configuration. [Dean Gaudet]
10867 *) popendir/pclosedir created to properly protect directory scanning.
10868 [Dean Gaudet] PR#525
10870 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
10871 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
10872 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
10875 *) The AccessFileName directive can now take more than one filename.
10876 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
10878 *) The new mod_mime_magic can be used to "magically" determine the type
10879 of a file if the extension is unknown. Based on the unix file(1)
10880 command. [Ian Kluft <ikluft@cisco.com>]
10882 *) We now determine and display the time spent processing a
10883 request if desired. [Jim Jagielski]
10885 *) mod_status: PID field of "dead" child slots no longer displays
10886 main httpd process's PID. [Jim Jagielski]
10888 *) Makefile.nt added - to build all the bits from the command line:
10889 nmake -f Makefile.nt
10890 Doesn't yet work properly. [Ben Laurie]
10892 *) Default text of 404 error is now "Not Found" rather than the
10893 potentially misleading "File Not Found". [Ken Coar]
10895 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
10896 for the net if we require people that actually need this data to
10897 enable it. [Linus Torvalds]
10899 *) directory_walk() is an expensive function, keep a little more state to
10900 avoid needless string counting. Add two new functions make_dirstr_parent
10901 and make_dirstr_prefix which replace all existing uses of make_dirstr.
10902 The new functions are a little less general than make_dirstr, but
10903 work more efficiently (less memory, less string counting).
10906 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
10907 to LDFLAGS) to avoid complications with lex rules in make files.
10908 [Dean Gaudet] PR#372
10910 *) run_method optimized to avoid needless scanning over NULLs in the
10911 module list. [Dean Gaudet]
10913 *) Revamp of (unix) scoreboard management code such that it avoids
10914 unnecessary traversals of the scoreboard on each hit. This is
10915 particularly important for high volume sites with a large
10916 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
10917 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
10918 httpd.h. [Dean Gaudet]
10920 *) In configurations using multiple Listen statements it was possible for
10921 busy sockets to starve other sockets of service. [Dean Gaudet]
10923 *) Added hook so standalone_main can be replaced at compile time
10924 (define STANDALONE_MAIN)
10927 *) Lowest-level read/write functions in buff.c will be replaced with
10928 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
10929 compile time. The default sfio discipline will behave as apache
10930 would without sfio compiled in.
10933 *) Enhance UserDir directive (mod_userdir) to accept a list of
10934 usernames for the 'disable' keyword, and add 'enable user...' to
10935 selectively *en*able userdirs if they're globally disabled.
10938 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
10939 will work with Netscape dbm files. (dbmmanage will probably not
10940 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
10942 *) Add a ListenBacklog directive to control the backlog parameter
10943 passed to listen(). Also change the default to 511 from 512.
10946 *) API: A new handler response DONE which informs apache that the
10947 request has been handled and it can finish off quickly, similar to
10948 how it handles errors. [Rob Hartill]
10950 *) Turn off chunked encoding after sending terminating chunk/footer
10951 so that we can't do it twice by accident. [Roy Fielding]
10953 *) mod_expire also issues Cache-Control: max-age headers.
10956 *) API: Added kill_only_once option for free_proc_chain so that it won't
10957 aggressively try to kill off specific children. For fastcgi.
10958 [Stanley Gambarin <gambarin@OpenMarket.com>]
10960 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
10962 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
10963 When used together, these cause mod_dir to emit HEIGHT and WIDTH
10964 attributes in the FancyIndexing IMG tags. [Ken Coar]
10966 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
10968 *) PORT: Added Windows NT support
10969 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
10971 Changes with Apache 1.2.6
10973 *) mod_include when using XBitHack Full would send ETags in addition to
10974 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
10975 [Dean Gaudet] PR#1133
10977 *) SECURITY: When a client connects to a particular port/addr, and
10978 gives a Host: header ensure that the virtual host requested can
10979 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
10981 *) Support virtual hosts with wildcard port and/or multiple ports
10982 properly. [Ed Korthof <ed@organic.com>]
10984 *) Fixed some case-sensitivity issues according to RFC2068.
10987 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
10988 and mod_include.c. [Dean Gaudet]
10990 *) Variable 'cwd' was being used pointlessly before being set.
10993 *) SIGURG doesn't exist on all platforms.
10994 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
10996 *) When an error occurs during a POST, or other operation with a
10997 request body, the body has to be read from the net before allowing
10998 a keepalive session to continue. [Roy Fielding] PR#1399
11000 *) When an error occurs in fcntl() locking suggest the user look up
11001 the docs for LockFile. [Dean Gaudet]
11003 *) table_set() and table_unset() did not deal correctly with
11004 multiple occurrences of the same key. [Stephen Scheck
11005 <sscheck@infonex.net>, Ben Laurie] PR#1604
11007 *) send_fd_length() did not calculate total_bytes_sent properly in error
11008 cases. [Ben Reser <breser@regnow.com>] PR#1366
11010 *) r->connection->user was allocated in the wrong pool causing corruption
11011 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
11013 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
11014 Also removed the auto-generated link to www.apache.org that was the
11015 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
11017 *) Multiple "close" tokens may have been set in the "Connection"
11018 header, not an error, but a waste.
11019 [Ronald.Tschalaer@psi.ch] PR#1683
11021 *) "basic" and "digest" auth tokens should be tested case-insensitive.
11022 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
11024 *) It appears the "257th byte" bug (see
11025 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
11026 at the 256th byte as well. Fixed. [Dean Gaudet]
11028 *) mod_rewrite would not handle %3f properly in some situations.
11031 *) Apache could generate improperly chunked HTTP/1.1 responses when
11032 the bputc() or rputc() functions were used by modules (such as
11033 mod_include). [Dean Gaudet]
11035 *) #ifdef wrap a few #defines in httpd.h to make life easier on
11036 some ports. [Ralf Engelschall]
11038 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
11040 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
11042 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
11044 Changes with Apache 1.2.5
11046 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
11047 only an issue on systems without a MAXDNAME define or where
11048 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
11050 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
11053 *) Fix core dump in the ftp proxy when reading incorrectly formatted
11054 directory listings. [Marc Slemko]
11056 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
11059 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
11060 is used to read various types of files such as htaccess and
11061 htpasswd files. [Marc Slemko]
11063 *) SECURITY: Ensure that the buffer returned by ht_time is always
11064 properly null terminated. [Marc Slemko]
11066 *) SECURITY: General mod_include cleanup, including fixing several
11067 possible buffer overflows and a possible infinite loop. This cleanup
11068 was done against 1.3 code and then backported to 1.2, the result
11069 is a large difference (due to indentation cleanup in 1.3 code).
11070 Users interested in seeing a smaller set of relevant differences
11071 should consider comparing against src/modules/standard/mod_include.c
11072 from the 1.3b3 release. Non-indentation changes to mod_include
11073 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
11075 *) SECURITY: Numerous changes to mod_imap in a general cleanup
11076 including fixing a possible buffer overflow. This cleanup also
11077 was done with 1.3 code as a basis, see the the previous note
11078 about mod_include. [Dean Gaudet]
11080 *) SECURITY: If a htaccess file can not be read due to bad
11081 permissions, deny access to the directory with a HTTP_FORBIDDEN.
11082 The previous behavior was to ignore the htaccess file if it could not
11083 be read. This change may make some setups with unreadable
11084 htaccess files stop working. PR#817 [Marc Slemko]
11086 *) SECURITY: no2slash() was O(n^2) in the length of the input.
11087 Make it O(n). This inefficiency could be used to mount a denial
11088 of service attack against the Apache server. Thanks to
11089 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
11090 this. [Dean Gaudet]
11092 *) mod_include used uninitialized data for some uses of && and ||.
11093 [Brian Slesinsky <bslesins@wired.com>] PR#1139
11095 *) mod_imap should decline all non-GET methods.
11096 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
11098 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
11100 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
11101 r->filename. Since those two are meant to be in sync with each other
11102 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
11104 *) mod_include did not properly handle all possible redirects from sub-
11105 requests. [Ken Coar]
11107 *) Inetd mode (which is buggy) uses timeouts without having setup the
11108 jmpbuffer. [Dean Gaudet] PR#1064
11110 *) Work around problem under Linux where a child will start looping
11111 reporting a select error over and over.
11112 [Rick Franchuk <rickf@transpect.net>] PR#1107
11114 Changes with Apache 1.2.4
11116 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
11117 always making requests with the full-URI instead of just the URI path.
11118 [Marc Slemko, Roy Fielding]
11120 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
11121 on this platform. [Marc Slemko]
11123 Changes with Apache 1.2.3
11125 *) The request to a remote proxy was mangled if it was generated as the
11126 result of a ProxyPass directive. URL schemes other than http:// were not
11127 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
11128 PR#812 [Lars Eilebrecht]
11130 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11131 information for case where proxy module is not available. [Marc Slemko]
11133 *) Force proxy to always respond as HTTP/1.0, which it was failing to
11134 do for errors and cached responses. [Roy Fielding]
11136 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
11138 Changes with Apache 1.2.2 [not released]
11140 *) Fixed another long-standing bug in sub_req_lookup_file where it would
11141 happily skip past access checks on subdirectories looked up with relative
11142 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
11145 *) Add lockfile name to error message printed out when
11146 USE_FLOCK_SERIALIZED_ACCEPT is defined.
11149 *) Enhanced the chunking and error handling inside the buffer functions.
11150 [Dean Gaudet, Roy Fielding]
11152 *) When merging the main server's <Directory> and <Location> sections into
11153 a vhost, put the main server's first and the vhost's second. Otherwise
11154 the vhost can't override the main server. [Dean Gaudet] PR#717
11156 *) The <Directory> code would merge and re-merge the same section after
11157 a match was found, possibly causing problems with some modules.
11160 *) Fixed an infinite loop in mod_imap for references above the server root.
11161 [Dean Gaudet] PR#748
11163 *) mod_include cleanup showed that handle_else was being used to handle
11164 endif. It didn't cause problems, but it was cleaned up too.
11167 *) Last official synchronization of mod_rewrite with author version (because
11168 mod_rewrite is now directly developed by the author at the Apache Group):
11169 o added diff between mod_rewrite 3.0.6+ and 3.0.9
11170 minus WIN32/NT stuff, but plus copyright removement.
11172 - workaround for detecting infinite rewriting loops
11173 - fixed setting of env vars when "-" is used as subst string
11174 - fixed forced response code on redirects (PR#777)
11175 - fixed cases where r->args is ""
11176 - kludge to disable locking on pipes under braindead SunOS
11177 - fix for rewritelog in cases where remote hostname is unknown
11178 - fixed totally damaged request_rec walk-back loop
11179 o remove static from local data and add static to global ones.
11180 o replaced ugly proxy finding stuff by simple
11181 find_linked_module("mod_proxy") call.
11182 o added missing negation char on rewritelog()
11183 o fixed a few comment typos
11184 [Ralf S. Engelschall]
11186 *) Anonymous_LogEmail was logging on each subrequest.
11187 [Dean Gaudet] PR#421, PR#868
11189 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11190 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11191 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11192 Additionally mod_browser now triggers during translate_name to workaround
11193 a deficiency in the header_parse phase.

11218 what to do with it; otherwise, the body would be mistaken for the
11219 next request on a persistent connection. discard_request_body()
11220 has been added to take care of that. [Roy Fielding] PR#378
11222 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
11223 release version number, such that it always increases along the
11224 same lines as our source code branching. [Roy Fielding]
11226 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
11228 Changes with Apache 1.2.1
11230 *) SECURITY: Don't serve file system objects unless they are plain files,
11231 symlinks, or directories. This prevents local users from using pipes
11232 or named sockets to invoke programs for an extremely crude form of
11235 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
11236 could contain "../" allowing a local user to "publish" any file on
11237 the system. No slashes are allowed now. [Dean Gaudet]
11239 *) SECURITY: It was possible to violate the symlink Options using mod_dir
11240 (headers, readmes, titles), mod_negotiation (type maps), or
11241 mod_cern_meta (meta files). [Dean Gaudet]
11243 *) SECURITY: Apache will refuse to run as "User root" unless
11244 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
11246 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
11247 if it contained a .htaccess disallowing symlinks. This is contrary
11248 to the rule that symlink permissions are tested with the symlink
11249 options of the parent directory. [Dean Gaudet] PR#353
11251 *) CONFIG: The LockFile directive can be used to place the serializing
11252 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
11253 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
11256 *) Request processing now retains state of whether or not the request
11257 body has been read, so that internal redirects and subrequests will
11258 not try to read it twice (and block). [Roy Fielding]
11260 *) Add a placeholder in modules/Makefile to avoid errors with certain
11261 makes. [Marc Slemko]
11263 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
11264 [Dean Gaudet] PR#644
11266 *) mod_include was not properly changing the current directory.
11267 [Marc Slemko] PR#742
11269 *) Attempt to work around problems with third party libraries that do not
11270 handle high numbered descriptors (examples include bind, and
11271 solaris libc). On all systems apache attempts to keep all permanent
11272 descriptors above 15 (called the low slack line). Solaris users
11273 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
11274 which keeps all non-FILE * descriptors above 255. On all systems
11275 this should make supporting large numbers of vhosts with many open
11276 log files more feasible. If this causes trouble please report it,
11277 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
11278 [Dean Gaudet] various PRs
11280 *) Related to the last entry, network sockets are now opened before
11281 log files are opened. The only known case where this can cause
11282 problems is under Solaris with many virtualhosts and many Listen
11283 directives. But using -DHIGH_SLACK_LINE=256 described above will
11284 work around this problem. [Dean Gaudet]
11286 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
11289 *) Improved unix error response logging. [Marc Slemko]
11291 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
11292 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
11293 when a URL http://... was used in conjunction with a special
11294 redirect flag, e.g. R=permanent, the permanent status was lost.
11295 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>, Ralf S. Engelschall]
11297 *) If an object has multiple variants that are otherwise equal Apache
11298 would prefer the last listed variant rather than the first.
11299 [Paul Sutton] PR#94
11301 *) "make clean" at the top level now removes *.o. [Dean Gaudet] PR#752
11303 *) mod_status dumps core in inetd mode. [Marc Slemko and Roy Fielding]
11306 *) pregsub had an off-by-1 in its error checking code. [Alexei Kosut]

11329 Changes with Apache 1.2
11331 Changes with Apache 1.2b11
11333 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
11335 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
11336 [Doug MacEachern, Rob Hartill]
11338 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
11339 reading from one buffer and writing to another, at least until it has
11340 a custom timeout handler. [Roy Fielding and Petr Lampa]
11342 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
11343 apparently due to a mismatch between sigaction and setjmp.
11344 [Roy Fielding] PR#502
11346 *) Log correct status code if we timeout before receiving a request (408)
11347 or if we received a request-line that was too long to process (414).
11348 [Ed Korthof and Roy Fielding] PR#601
11350 *) Virtual hosts with the same ServerName, but on different ports, were
11351 not being selected properly. [Ed Korthof]
11353 *) Added code to return the requested IP address from proxy_host2addr()
11354 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
11355 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
11356 [Chuck Murcko] PR#614
11358 *) If multiple requests on a single connection are used to retrieve
11359 data from different virtual hosts, the virtual host list would be
11360 scanned starting with the most recently used VH instead of the first,
11361 causing most virtual hosts to be ignored.
11362 [Paul Sutton and Martin Mares] PR#610
11364 *) The OS/2 handling of process group was broken by a porting patch for
11365 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
11367 *) Inherit virtual server port from main server if none (or "*") is
11368 given for VirtualHost. [Dean Gaudet] PR#576
11370 *) If the lookup for a DirectoryIndex name with content negotiation
11371 has found matching variants, but none are acceptable, return the
11372 negotiation result if there are no more DirectoryIndex names to lookup.
11373 [Petr Lampa and Roy Fielding]
11375 *) If a soft_timeout occurs after keepalive is set, then the main child
11376 loop would try to read another request even though the connection
11377 has been aborted. [Roy Fielding]
11379 *) Configure changes: Allow for whitespace at the start of a
11380 Module declaration. Also, be more understanding about the
11381 CC=/OPTIM= format in Configuration. Finally, fix compiler
11382 flags if using HP-UX's cc compiler. [Jim Jagielski]
11384 *) Subrequests and internal redirects now inherit the_request from the
11385 original request-line. [Roy Fielding]
11387 *) Test for error conditions before creating output header fields, since
11388 we don't want the error message to include those fields. Likewise,
11389 reset the content_language(s) and content_encoding of the response
11390 before generating or redirecting to an error message, since the new
11391 message will have its own Content-* definitions. [Dean Gaudet]
11393 *) Restored the semantics of headers_out (headers sent only with 200..299
11394 and 304 responses) and err_headers_out (headers sent with all responses).
11395 Avoid the overhead of copying tables if err_headers_out is empty
11396 (the usual case). [Roy Fielding]
11398 *) Fixed a couple places where a check for the default Content-Type was
11399 not properly checking both the value configured by the DefaultType
11400 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
11401 of DEFAULT_TYPE to match the documented default (text/plain).
11402 [Dean Gaudet] PR#506
11404 *) Escape the HTML-sensitive characters in the Request-URI that is
11405 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
11407 *) Properly initialize the flock structures used by the mutex locking
11408 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
11411 *) The method for determining PATH_INFO has been restored to the pre-1.2b
11412 (and NCSA httpd) definition wherein it was the extra path info beyond
11413 the CGI script filename. The environment variable FILEPATH_INFO has
11414 been removed, and instead we supply the original REQUEST_URI to any
11415 script that wants to be Apache-specific and needs the real URI path.
11416 This solves a problem with existing scripts that use extra path info
11417 in the ScriptAlias directive to pass options to the CGI script.
11420 *) The _default_ change in 1.2b10 will change the behaviour on configs
11421 that use multiple Listen statements for listening on multiple ports.
11422 But that change is necessary to make _default_ consistent with other
11423 forms of <VirtualHost>. It requires such configs to be modified
11424 to use <VirtualHost _default_:*>. The documentation has been
11425 updated. [Dean Gaudet] PR#530
11427 *) If an ErrorDocument CGI script is used to respond to an error
11428 generated by another CGI script which has already read the message
11429 body of the request, the server would block trying to read the
11430 message body again. [Rob Hartill]
11432 *) signal() replacement conflicted with a define on QNX (and potentially
11433 other platforms). Fixed. [Ben Laurie] PR#512
11435 Changes with Apache 1.2b10
11437 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
11438 to be configured via -D in Configuration. [Dean Gaudet] PR#449
11440 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
11442 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
11444 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
11445 config, in case the hostent struct returned is trash.
11446 [Chuck Murcko] PR #491
11448 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
11449 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
11451 Changes with Apache 1.2b9 [never announced]
11453 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
11454 changes and in anticipation of 1.2 final release. [Roy Fielding]
11456 *) Fix problem with scripts not receiving a SIGPIPE when client drops
11457 the connection (e.g., when user presses Stop). Apache will now stop
11458 trying to send a message body immediately after an error from write.
11459 [Roy Fielding and Nathan Kurz] PR#335
11461 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
11462 than mod_alias, and mod_alias has higher priority than mod_proxy;
11463 rearranged other modules to enhance understanding of their purpose
11464 and relative order (and maybe even reduce some overhead).
11465 [Roy Fielding and Sameer Parekh]
11467 *) Fix graceful restart. Eliminate many signal-related race
11468 conditions in both forms of restart, and in SIGTERM. See
11469 htdocs/manual/stopping.html for details on stopping and
11470 restarting the parent. [Dean Gaudet]
11472 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
11473 memory allocator to avoid a behaviour that required extra blocks to
11474 be allocated. [Dean Gaudet]
11476 *) Allow suexec to access files relative to current directory but not
11477 above. (Excluding leading / or any .. directory.) [Ken Coar]
11480 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
11481 PR#367, 368, 354, 453
11483 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
11484 while obtaining the /~user and save the username in a separate data
11485 area so that it won't be overwritten by the call to getgrgid(), and
11486 fix some misuse of the pool string allocation functions. Also fixes
11487 a general problem with parsing URL query info into args for CGI scripts.
11488 [Roy Fielding] PR#339, 367, 354, 453
11490 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
11492 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
11494 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
11495 AuthDBAuthoritative. [Marc Slemko] PR#420
11497 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
11499 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
11500 object that can't be PUT, or FOOBAR for some method FOOBAR that
11501 apache doesn't know about at all). Log 404s that occur in mod_include.
11502 [Paul Sutton, John Van Essen]
11504 *) If a soft timeout (or lingerout) occurs while trying to flush a
11505 buffer or write inside buff.c or fread'ing from a CGI's output,
11506 then the timeout would be ignored. [Roy Fielding] PR#373
11508 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
11509 parsing of headers. If the terminating empty-line CRLF occurs starting
11510 at the 256th or 257th byte of output, then Navigator will think a normal
11511 image is invalid. We are guessing that this is because their initial
11512 read of a new request uses a 256 byte buffer. We check the bytes written
11513 so far and, if we are about to tickle the bug, we instead insert a
11514 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
11516 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
11517 of an external redirection. [Roy Fielding and Paul Sutton]
11519 *) Configure would create a broken Makefile if the configuration file
11520 contained a commented-out Rule. [Roy Fielding]
11522 *) Promote per_dir_config and subprocess_env from the subrequest to the
11523 main request in mod_negotiation. In particular this fixes a bug
11524 where <Files> sections wouldn't properly apply to negotiated content.
11527 *) Fix a potential deadlock in mod_cgi script_err handling.
11528 [Ralf S. Engelschall]
11530 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
11531 [Mitchell Blank Jr]
11533 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
11534 .htaccess files because the RewriteBase was not replaced correctly.
11535 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
11536 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
11538 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
11539 1.x the settings are those of pre-1.2b8. For 2.x we include
11540 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
11541 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
11542 [Dean Gaudet] PR#336, PR#340
11544 *) Redirect did not preserve ?query_strings when present in the client's
11545 request. [Dean Gaudet]
11547 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
11549 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
11551 *) Add UnixWare compile/install instructions. [Chuck Murcko]
11553 *) Add mod_example (illustration of API techniques). [Ken Coar]
11555 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
11557 *) Improve handling of directories when filenames have spaces in them.
11560 *) For hosts with multiple IP addresses, try all additional addresses if
11561 necessary to get a connect. Fail only if hostent address list is
11562 exhausted. [Chuck Murcko]
11564 *) More signed/unsigned port fixes. [Dean Gaudet]
11566 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
11569 Changes with Apache 1.2b8
11571 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
11572 to it. [Marc Slemko]
11574 *) The addition of <Location> and <File> directives made the
11575 sub_req_lookup_simple() function bogus, so we now handle
11576 the special cases directly. [Dean Gaudet]
11578 *) We now try to log where the server is dumping core when a fatal
11579 signal is received. [Ken Coar]
11581 *) Improved lingering_close by adding a special timeout, removing the
11582 spurious log messages, removing the nonblocking settings (they
11583 are not needed with the better timeout), and adding commentary
11584 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
11585 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
11587 *) Send error messages about setsockopt failures to the server error
11588 log instead of stderr. [Roy Fielding]
11590 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
11592 *) Stopgap solution for CGI 3-second delay with server-side includes: if
11593 processing a subrequest, allocate memory from r->main->pool instead
11594 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
11595 in the middle of an SSI request. [Dean Gaudet] PR #122
11597 *) Fixed status of response when POST is received for a nonexistent URL
11598 (was sending 405, now 404) and when any method is sent with a
11599 full-URI that doesn't match the server and the server is not acting
11600 as a proxy (was sending 501, now 403). [Roy Fielding]
11602 *) Host port changed to unsigned short. [Ken Coar] PR #276
11604 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
11606 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
11608 *) Report extra info from errno with many errors that cause httpd to exit.
11609 spawn_child, popenf, and pclosef now have valid errno returns in the
11610 event of an error. Correct problems where errno was stomped on
11611 before being reported. [Dean Gaudet]
11613 *) In the proxy, if the cache filesystem was full, garbage_coll() was
11614 never called, and thus the filesystem would remain full indefinitely.
11615 We now also remove incomplete cache files left if the origin server
11616 didn't send a Content-Length header and either the client has aborted
11617 transfer or bwrite() to client has failed. [Petr Lampa]
11619 *) Fixed the handling of module and script-added header fields.
11620 Improved the interface for sending header fields and reduced
11621 the duplication of code between sending okay responses and errors.
11622 We now always send both headers_out and err_headers_out, and
11623 ensure that the server-reserved fields are not being overridden,
11624 while not overriding those that are not reserved. [Roy Fielding]
11626 *) Moved transparent content negotiation fields to err_headers_out
11627 to reflect above changes. [Petr Lampa]
11629 *) Fixed the determination of whether or not we should make the
11630 connection persistent for all of the cases where some other part
11631 of the server has already indicated that we should not. Also
11632 improved the ordering of the test so that chunked encoding will
11633 be set whenever it is desired instead of only when KeepAlive
11634 is enabled. Added persistent connection capability for most error
11635 responses (those that do not indicate a bad input stream) when
11636 accessed by an HTTP/1.1 client. [Roy Fielding]
11638 *) Added missing timeouts for sending header fields, error responses,
11639 and the last chunk of chunked encoding, each of which could have
11640 resulted in a process being stuck in write forever. Using soft_timeout
11641 requires that the sender check for an aborted connection rather than
11642 continuing after an EINTR. Timeouts that used to be initiated before
11643 send_http_header (and never killed) are now initiated only within or
11644 around the routines that actually do the sending, and not allowed to
11645 propagate above the caller. [Roy Fielding]
11647 *) mod_auth_anon required an @ or a . in the email address, not both.
11650 *) per_dir_defaults weren't set correctly until directory_walk for
11651 name-based vhosts. This fixes an obscure bug with the wrong config
11652 info being used for vhosts that share the same ip as the server.
11655 *) Improved generation of modules/Makefile to be more generic for
11656 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
11658 *) Generate makefile dependency for Configuration based on the actual
11659 name given when running the Configure process. [Dean Gaudet]
11661 *) Fixed problem with vhost error log not being set prior to
11662 initializing virtual hosts. [Dean Gaudet]
11664 *) Fixed infinite loop when a trailing slash is included after a type map
11665 file URL (extra path info). [Petr Lampa]
11667 *) Fixed server status updating of per-connection counters. [Roy Fielding]
11669 *) Add documentation for DNS issues (reliability and security), and try
11670 to explain the virtual host matching process. [Dean Gaudet]
11672 *) Try to continue gracefully by disabling the vhost if a DNS lookup
11673 fails while parsing the configuration file. [Dean Gaudet]
11675 *) Improved calls to setsockopt. [Roy Fielding]
11677 *) Negotiation changes: Don't output empty content-type in variant list;
11678 Output charset in variant list; Return sooner from handle_multi() if
11679 no variants found; Add handling of '*' wildcard in Accept-Charset.
11680 [Petr Lampa and Paul Sutton]
11682 *) Fixed overlaying of request/sub-request notes and headers in
11683 mod_negotiation. [Dean Gaudet]
11685 *) If two variants' charset quality are equal and one is the default
11686 charset (iso-8859-1), then prefer the variant that was specifically
11687 listed in Accept-Charset instead of the default. [Petr Lampa]
11689 *) Memory allocation problem in push_array() -- it would corrupt memory
11690 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
11692 *) invoke_handler() doesn't handle mime arguments in content-type
11693 [Petr Lampa] PR#160
11695 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
11698 *) Fixed problem with ErrorDocument not working for virtual hosts
11699 due to one of the performance changes in 1.2b7. [Dean Gaudet]
11701 *) Log an error message if we get a request header that is too long,
11702 since it may indicate a buffer overflow attack. [Marc Slemko]
11704 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
11705 not reject URLs without a double-slash, as per RFC2068 section 3.2.
11706 [Ken Coar] PR #146, #187
11708 *) Added table entry placeholder for new header_parser callback
11709 in all of the distributed modules. [Ken Coar] PR #191
11711 *) Allow for cgi files without the .EXE extension on them under OS/2.
11712 [Garey Smiley] PR #59
11714 *) Fixed error message when resource is not found and URL contains
11715 path info. [Petr Lampa and Dean Gaudet] PR #40
11717 *) Fixed user and server confusion over what should be a virtual host
11718 and what is the main server, resulting in access to something
11719 other than the name defined in the virtualhost directive (but
11720 with the same IP address) failing. [Dean Gaudet]
11722 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
11723 AIX; improves the redirection stuff to enable the users to generally
11724 redirect to http, https, gopher and ftp; added TIME variable for
11725 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
11726 special patterns >STRING, <STRING and =STRING to RewriteCond, which
11727 can be used in conjunction with %{TIME} or other variables to create
11728 time-dependent rewriting rules. [Ralf S. Engelschall]
11730 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
11731 Module authors may need to adjust their code for proper cleanup to take
11732 place (that is, call note_cleanups_for_fd()). This change fixes problems
11733 with file descriptors being erroneously closed when the proxy module was
11734 in use. [Ben Laurie]
11736 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
11737 initgroups() to hose the group information needed for later
11738 comparisons. [Randy Terbush]
11740 *) Remove unnecessary call to va_end() in create_argv() which
11741 caused a SEGV on some systems.
11743 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
11746 *) Clear memory allocated for listeners. [Randy Terbush]
11748 *) Improved handling of IP address as a virtualhost address and
11749 introduced "_default_" as a synonym for the default vhost config.
11750 [Dean Gaudet] PR #212
11752 Changes with Apache 1.2b7
11754 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
11756 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
11758 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
11759 - replace protocol response numbers with symbols
11760 - save variant-list into main request notes
11761 - free allocated memory from subrequests
11762 - merge notes, headers_out and err_headers_out
11764 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
11765 "HTTP/#.# ###*" to be more lenient about what we accept.
11768 *) more proxy FTP bug fixes:
11769 - Changed send_dir() to remove user/passwd from displayed URL.
11770 - Changed login error messages to be more descriptive.
11771 - remove setting of SO_DEBUG socket option
11772 - Make ftp_getrc() more lenient about multiline responses,
11773 specifically, 230 responses which don't have continuation 230-
11774 on each line). These seem to be all NT FTP servers, and while
11775 perhaps questionable, they appear to be legal by RFC 959.
11776 - Add missing kill_timeout() after transfer to user completes.
11779 *) Fixed problem where a busy server could hang when restarting
11780 after being sent a SIGHUP due to child processes not exiting.
11783 *) Modify mod_include escaping so a '\' only signifies an escaped
11784 character if the next character is one that needs
11785 escaping. [Ben Laurie]
11787 *) Eliminated possible infinite loop in mod_imap when relative URLs are
11788 used with a 'base' directive that does not have a '/' in it.
11789 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
11791 *) Reduced the default timeout from 1200 seconds to 300, and the
11792 one in the sample configfile from 400 to 300. [Marc Slemko]
11794 *) Stop vbprintf from crashing if given a NULL string pointer;
11795 print (null) instead. [Ken Coar]
11797 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
11798 [Marc Slemko and Roy Fielding]
11800 *) Fixed problem with mod_cgi-generated internal redirects trying to
11801 read the request message-body twice. [Archie Cobbs and Roy Fielding]
11803 *) Reduced timeout on lingering close, removed possibility of a blocked
11804 read causing the child to hang, and stopped logging of errors if
11805 the socket is not connected (reset by client). [Roy Fielding]
11807 *) Rearranged main child loop to remove duplication of code in
11808 select/accept and keep-alive requests, fixed several bugs regarding
11809 checking scoreboard_image for exit indication and failure to
11810 account for all success conditions and trap all error conditions,
11811 prevented multiple flushes before closing the socket; close the entire
11812 socket buffer instead of just one descriptor, prevent logging of
11813 EPROTO and ECONNABORTED on platforms where supported, and generally
11814 improved readability. [Roy Fielding]
11816 *) Extensive performance improvements. Cleaned up inefficient use of
11817 auto initializers, multiple is_matchexp calls on a static string,
11818 and excessive merging of response_code_strings. [Dean Gaudet]
11820 *) Added double-buffering to mod_include to improve performance on
11821 server-side includes. [Marc Slemko]
11823 *) Several fixes for suexec wrapper. [Randy Terbush]
11824 - Make wrapper work for files on NFS filesystem.
11825 - Fix portability problem of MAXPATHLEN.
11826 - Fix array overrun problem in clean_env().
11827 - Fix allocation of PATH environment variable
11829 *) Removed extraneous blank line is description of mod_status chars.
11832 *) Logging of errors from the call_exec routine simply went nowhere,
11833 since the logfile fd has been closed, so now we send them to stderr.
11834 [Harald T. Alvestrand]
11836 *) Fixed core dump when DocumentRoot is a CGI.
11837 [Ben Laurie, reported by geddis@tesserae.com]
11839 *) Fixed potential file descriptor leak in mod_asis; updated it and
11840 http_core to use pfopen/pfclose instead of fopen/fclose.
11841 [Randy Terbush and Roy Fielding]
11843 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
11844 as the DEC Alpha which is 64-bit but uses 32-bit ints.
11845 [Dean Gaudet and Ken Coar]
11847 *) Return a 302 response code to the client when sending a redirect
11848 due to a missing trailing '/' on a directory instead of a 301; now
11849 it is cacheable. [Markus Gyger]
11851 *) Fix condition where, if a bad directive occurs in .htaccess, and
11852 sub_request() goes first to this directory, then log_reason() will
11853 SIGSEGV because it doesn't have initialized r->per_dir_config.
11854 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
11856 *) Fix handling of lang_index in is_variant_better(). This was
11857 causing problems which resulted in the server sending the
11858 wrong language document in some cases. [Petr Lampa]
11860 *) Remove free() from clean_env() in suexec wrapper. This was nuking
11861 the clean environment on some systems.
11863 *) Tweak byteserving code (e.g. serving PDF files) to work around
11864 bugs in Netscape Navigator and Microsoft Internet Explorer.
11865 Emit Content-Length header when sending multipart/byteranges.
11868 *) Port to HI-UX/WE2. [Nick Maclaren]
11870 *) Port to HP MPE operating system for HP 3000 machines
11871 [Mark Bixby <markb@cccd.edu>]
11873 *) Fixed bug which caused a segmentation fault if only one argument
11874 given to RLimit* directives. [Ed Korthof]
11876 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
11878 *) Improved buffered output to the client by delaying the flush decision
11879 until the BUFF code is actually about to read the next request.
11880 This fixes a problem introduced in 1.2b5 with clients that send
11881 an extra CRLF after a POST request. Also improved chunked output
11882 performance by combining writes using writev() and removing as
11883 many bflush() calls as possible. NOTE: Platforms without writev()
11884 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
11885 or Configure, unless we have already done so. [Dean Gaudet]
11887 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
11889 *) Fixed mod_info output corruption bug introduced by buffer overflow
11890 fixes. [Dean Gaudet]
11892 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
11893 for the special case of a 304 response. [Paul Sutton]
11895 *) Improved handling of TRACE method by bypassing normal method handling
11896 and header parsing routines; fixed Allow response to always allow TRACE.
11899 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
11901 *) Cleaned-up some of the generated HTML. [Ken Coar]
11903 Changes with Apache 1.2b6
11905 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
11907 *) Fix typo introduced in fix for potential infinite loop around
11908 accept() in child_main(). This change caused the rev to 1.2b6.
11909 1.2b5 was never a public beta.
11911 Changes with Apache 1.2b5
11913 *) Change KeepAlive semantics (On|Off instead of a number), add
11914 MaxKeepAliveRequests directive. [Alexei Kosut]
11916 *) Various NeXT compilation patches, as well as a change in
11917 regex/regcomp.c since that file also used a NEXT define.
11920 *) Allow * to terminate the end of a directory match in mod_dir.
11921 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
11923 *) Don't call can_exec() if suexec_enabled. Calling this requires
11924 scripts executed by the suexec wrapper to be world executable, which
11925 defeats one of the advantages of running the wrapper. [Randy Terbush]
11927 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
11930 *) Migration from sprintf() to snprintf() to avoid buffer
11931 overflows. [Marc Slemko]
11933 *) Provide portable snprintf() implementation (ap_snprintf)
11934 as well as *cvt family. [Jim Jagielski]
11936 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
11939 *) Remove mod_fastcgi.c from the distribution. This module appears
11940 to be maintained more through the Open Market channels and should
11941 continue to be easily available at http://www.fastcgi.com/
11943 *) Fixed bug in modules/Makefile that wouldn't allow building in more
11944 than one subdirectory (or cleaning, either). [Jeremy Laidman]
11946 *) mod_info assumed that the config files were relative to ServerRoot.
11949 *) CGI scripts called as an error document resulting from failed
11950 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
11952 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
11955 *) Properly check errno to prevent display of a directory index
11956 when server receives a long enough URL to confuse stat().
11959 *) Several security enhancements to suexec wrapper. It is _highly_
11960 recommended that previously installed versions of the wrapper
11961 be replaced with this version. [Randy Terbush, Jason Dour]
11963 - ~user execution now properly restricted to ~user's home
11964 directory and below.
11965 - execution restricted to UID/GID > 100
11966 - restrict passed environment to known variables
11967 - call setgid() before initgroups() (portability fix)
11968 - remove use of setenv() (portability fix)
11970 *) Add HTTP/1.0 response forcing. [Ben Laurie]
11972 *) Add access control via environment variables. [Ben Laurie]
11974 *) Add rflush() function. [Alexei Kosut]
11976 *) remove duplicate pcalloc() call in new_connection().
11978 *) Fix incorrect comparison which could allow number of children =
11979 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
11980 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
11982 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
11983 AIX PS/2, CONVEXOS. [Jim Jagielski]
11985 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
11986 It's more portable. [Martin Kraemer]
11988 *) Replace references to make in Makefile.tmpl with $(MAKE).
11991 *) Add ProxyBlock directive w/IP address caching. Add IP address
11992 caching to NoCache directive as well. ProxyBlock works with all
11993 handlers; NoCache now also works with FTP for anonymous logins.
11994 Still more code cleanup. [Chuck Murcko]
11996 *) Add "header parse" API hook [Ben Laurie]
11998 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
12000 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
12002 *) Correctly allow access and auth directives in <Files> sections in
12003 server config files. [Alexei Kosut]
12005 *) Fix bug with ServerPath that could cause certain files to be not
12006 found by the server. [Alexei Kosut]
12008 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
12009 double-quote from text and so that it properly checks for unsupported
12010 status codes using the new index_of_response interface. [Roy Fielding]
12012 *) Multiple fixes to the lingering_close code in order to avoid being
12013 interrupted by a stray timeout, to avoid lingering on a connection
12014 that has already been aborted or never really existed, to ensure that
12015 we stop lingering as soon as any error condition is received, and to
12016 prevent being stuck indefinitely if the read blocks. Also improves
12017 reporting of error conditions. [Marc Slemko and Roy Fielding]
12019 *) Fixed initialization of parameter structure for sigaction.
12020 [mgyger@itr.ch, Adrian Filipi-Martin]
12022 *) Fixed reinitializing the parameters before each call to accept and
12023 select, and removed potential for infinite loop in accept.
12024 [Roy Fielding, after useful PR from adrian@virginia.edu]
12026 *) Fixed condition where, if a child fails to fork, the scoreboard would
12027 continue to say SERVER_STARTING forever. Eventually, the main process
12028 would refuse to start new children because count_idle_servers() will
12029 count those SERVER_STARTING entries and will always report that there
12030 are enough idle servers. [Phillip Vandry]
12032 *) Fixed bug in bcwrite regarding failure to account for partial writes.
12033 Avoided calling bflush() when the client is pipelining requests.
12034 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
12036 *) Added description of "." mode in server-status [Jim Jagielski]
12038 Changes with Apache 1.2b4
12040 *) Fix possible race condition in accept_mutex_init() that
12041 could leave a small security hole open allowing files to be
12042 overwritten in cases where the server UID has write permissions.
12045 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
12047 *) Fix portablity problem in util_script where ARG_MAX may not be
12048 defined for some systems.
12050 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
12053 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
12054 style magic #! token for better script portability. [Garey Smiley]
12056 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
12057 execution for ~userdir CGI. [Jason Dour]
12059 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
12061 *) Fix month off by one in suexec wrapper logging.
12063 Changes with Apache 1.2b3:
12065 *) Fix error in mod_cgi which could cause resources not to be properly
12066 freed, or worse. [Dean Gaudet]
12068 *) Fix find_string() NULL pointer dereference. [Howard Fear]
12070 *) Add set_flag_slot() at the request of Dirk and others.
12073 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
12075 *) Add changes to improve the error message given for invalid
12076 ServerName parameters. [Dirk vanGulik]
12078 *) Add "Authoritative" directive for Auth modules that don't
12079 currently have it. This gives admin control to assign authoritative
12080 control to an authentication scheme and allow "fall through" for
12081 those authentication modules that aren't "Authoritative" thereby
12082 allowing multiple authentication mechanisms to be chained.
12085 *) Remove requirement for ResourceConfig/AccessConfig if not using
12086 the three config file layout. [Randy Terbush]
12088 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
12090 *) Changes to suexec wrapper to fix the following problems:
12091 1. symlinked homedirs will kill ~userdirs.
12092 2. initgroups() on Linux 2.0.x clobbers gr->grid.
12093 3. CGI command lines paramters problems
12094 4. pw-pwdir for "docroot check" still the httpd user's pw record.
12095 [Randy Terbush, Jason Dour]
12097 *) Change create_argv() to accept variable arguments. This fixes
12098 a problem where arguments were not getting passed to the CGI via
12099 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
12101 *) Collapse multiple slashes in path URLs to properly apply
12102 handlers defined by <Location>. [Alexei Kosut]
12104 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
12106 *) Improve the accuracy of request duration timings by setting
12107 r->request_time in read_request_line() instead of read_request().
12110 *) Reset timeout while reading via get_client_block() in mod_cgi.c
12111 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
12113 *) Add the ability to pass different Makefile.tmpl files to Configure
12114 using the -make flag. [Rob Hartill]
12116 *) Fix coredump triggered when sending a SIGHUP to the server caused
12117 by an assertion failure, in turn caused by an uninitialised field in a
12121 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
12122 PATH_INFO from previous versions of Apache (in certain situations,
12123 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
12124 [later removed in 1.2b11]
12126 *) Add rwrite() function to API to allow for sending strings of
12127 arbitrary length. [Doug MacEachern]
12129 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
12131 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
12132 NeXT. [Jim Jagielski]
12134 *) Removed recent modification to promote the status code on internal
12135 redirects, since the correct fix was to change the default log format
12136 in mod_log_config so that it outputs the original status. [Rob Hartill]
12138 Changes with Apache 1.2b2:
12140 *) Update set_signals() to use sigaction() for setting handlers.
12141 This appears to fix a re-entrant problem in the seg_fault()
12142 bus_error() handlers. [Randy Terbush]
12144 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
12146 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
12148 *) proxy_http.c bugfixes: [Chuck Murcko]
12149 1) fixes possible NULL pointer reference w/NoCache
12150 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
12151 host would cache nothing if it was in the local domain,
12152 and the local domain was in the NoCache list)
12153 3) Adds Host: header when not available
12154 4) Some code cleanup and clarification
12156 *) mod_include.c bugfixes:
12157 1) Fixed an ommission that caused include variables to not
12158 be parsed in config errmsg directives [Howard Fear]
12159 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
12160 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
12161 4) Allow backslash-escaping to all quoted text
12162 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
12163 5) Pass variable to command line if not set in XSSI's env
12166 *) Fix infinite loop when processing Content-language lines in
12167 type-map files. [Alexei Kosut]
12169 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
12171 *) Fixed problem in set_[user|group] that prevented CGI execution
12172 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
12174 *) Added PORTING information file. [Jim Jagielski]
12176 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
12178 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
12180 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
12181 USE_FCNTL_SERIALIZED_ACCEPT was intended.
12183 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
12184 which caused problems of systems where socket s_addr is >32bits.
12186 *) Added comment to explain (r->chunked = 1) side-effect in
12187 http_protocol.c [Roy Fielding]
12189 *) Replaced use of index() in mod_expires.c with more appropriate
12190 and portable isdigit() test. [Ben Laurie]
12192 *) Updated Configure for ...
12193 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
12194 *-dg-dgux* (bad pattern match)
12195 QNX (DEF_WANTHSREGEX=yes)
12196 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
12198 *-unixware211 (new)
12199 and added some user diagnostic info. [Ben Laurie]
12201 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
12202 for better portability. [Jim Jagielski]
12204 *) Updated helpers/GuessOS for ...
12205 SCO 5 (recognize minor releases)
12206 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
12207 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
12208 IRIX64 (-sgi-irix64)
12209 ULTRIX (-unknown-ultrix)
12210 SINIX (-whatever-sysv4)
12211 NCR Unix (-ncr-sysv4)
12212 and fixed something in helpers/PrintPath [Ben Laurie]
12214 Changes with Apache 1.2b1
12216 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
12218 Changes with Apache 1.1.1
12220 *) Fixed bug where Cookie module would make two entries in the
12221 logfile for each access [Mark Cox]
12223 *) Fixed bug where Redirect in .htaccess files would cause memory
12224 leak. [Nathan Neulinger]
12226 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
12228 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
12230 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
12232 Changes with Apache 1.1.0
12234 *) Bring NeXT support up to date. [Takaaki Matsumoto]
12236 *) Bring QNX support up to date. [Ben Laurie]
12238 *) Make virtual hosts default to main server keepalive parameters.
12239 [Alexei Kosut, Ben Laurie]
12241 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
12243 *) Fix missing address family for connect, also remove unreachable statement
12244 in mod_proxy. [Ben Laurie]
12246 *) mod_env now turned on by default in Configuration.tmpl.
12248 *) Bugs which were fixed:
12249 a) yet more mod_proxy bugs [Ben Laurie]
12250 b) CGI works again with inetd [Alexei Kosut]
12251 c) Leading colons were stripped from passwords [osm@interguide.com]
12252 d) Another fix to multi-method Limit problem [jk@tools.de]
12254 Changes with Apache 1.1b4
12256 *) r->bytes_sent variable restored. [Robert Thau]
12258 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
12260 *) More possibly unsecure programs removed from the support directory.
12262 *) More mod_auth_msql authentication improvements.
12264 *) VirtualHosts based on Host: headers no longer conflict with the
12267 *) OS/2 compatibility enhancements. [Gary Smiley]
12269 *) POST now allowed to directory index CGI scripts.
12271 *) Actions now work with files of the default type.
12273 *) Bugs which were fixed:
12274 a) more mod_proxy bugs
12275 b) early termination of inetd requests
12276 c) compile warnings on several systems
12277 d) problems when scripts stop reading output early
12279 Changes with Apache 1.1b3
12281 *) Much of cgi-bin and all of cgi-src has been removed, due to
12282 various security holes found and that we could no longer support
12285 *) The "Set-Cookie" header is now special-cased to not merge multiple
12286 instances, since certain popular browsers can not handle multiple
12287 Set-Cookie instructions in a single header. [Paul Sutton]
12289 *) rprintf() added to buffer code, occurrences of sprintf removed.
12292 *) CONNECT method for proxy module, which means tunneling SSL should work.
12293 (No crypto needed) Also a NoCache config directive.
12295 *) Several API additions: pstrndup(), table_unset() and get_token()
12296 functions now available to modules.
12298 *) mod_imap fixups, in particular Location: headers are now complete
12301 *) New "info" module which reports on installed module set through a
12302 special URL, a la mod_status.
12304 *) "ServerPath" directive added - allows for graceful transition
12305 for Host:-header-based virtual hosts.
12307 *) Anonymous authentication module improvements.
12309 *) MSQL authentication module improvements.
12311 *) Status module design improved - output now table-based. [Ben Laurie]
12313 *) htdigest utility included for use with digest authentication
12316 *) mod_negotiation: Accept values with wildcards to be treated with
12317 less priority than those without wildcards at the same quality
12318 value. [Alexei Kosut]
12320 *) Bugs which were fixed:
12321 a) numerous mod_proxy bugs
12322 b) CGI early-termination bug [Ben Laurie]
12323 c) Keepalives not working with virtual hosts
12324 d) RefererIgnore problems
12325 e) closing fd's twice in mod_include (causing core dumps on
12326 Linux and elsewhere).
12328 Changes with Apache 1.1b2
12331 a) core dumps in mod_digest
12332 b) truncated hostnames/ip address in the logs
12333 c) relative URL's in mod_imap map files
12335 Changes with Apache 1.1b1
12337 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12339 Changes with Apache 1.0.3
12341 *) Internal redirects which occur in mod_dir.c now preserve the
12342 query portion of a request (the bit after the question mark).
12345 *) Escape active characters '<', '>' and '&' in html output in
12346 directory listings, error messages and redirection links.
12349 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12351 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12354 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12356 *) Reset timeout timer after each successful fwrite() to the network.
12357 This patch adds a reset_timeout() procedure that is called by
12358 send_fd() to reset the timeout ever time data is written to the net.
12361 *) timeout() signal handler now checks for SIGPIPE and reports
12362 lost connections in a more user friendly way. [Rob Hartill]
12364 *) Location of the "scoreboard" file which used to live in /tmp is
12365 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12366 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12368 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12370 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12371 which caused a SEGV with cookies enabled
12373 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12376 *) Log the UNIX textual error returned by some system calls, in
12377 particular errors from accept() [David Robinson]
12379 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12381 Changes with Apache 1.0.2
12383 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12384 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12386 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12389 *) past changes to http_config.c to only use the
12390 setrlimit function on systems defining RLIMIT_NOFILE
12391 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12392 for SUNOS and prototypes the needed functions.
12394 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12397 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12399 *) Merge multiple headers from CGI scripts instead of taking last
12400 one. [David Robinson]
12402 *) Add support for SCO 5. [Ben Laurie]
12404 Changes with Apache 1.0.1
12406 *) Silence mod_log_referer and mod_log_agent if not configured
12409 *) Recursive includes can occur if the client supplies PATH_INFO data
12410 and the server provider uses relative links; as file.html
12411 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
12413 *) The replacement for initgroups() did not call {set,end}grent(). This
12414 had two implications: if anything else used getgrent(), then
12415 initgroups() would fail, and it was consuming a file descriptor.
12418 *) On heavily loaded servers it was possible for the scoreboard to get
12419 out of sync with reality, as a result of a race condition.
12420 The observed symptoms are far more Apaches running than should
12421 be, and heavy system loads, generally followed by catastrophic
12422 system failure. [Ben Laurie]
12424 *) Fix typo in license. [David Robinson]
12426 Changes with Apache 1.0.0 23 Nov 1995
12428 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
12430 Changes with Apache 0.8.16 05 Nov 1995
12432 *) New man page for 'httpd' added to support directory [David Robinson]
12434 *) .htgroup files can have more than one line giving members for a
12435 given group (each must have the group name in front), for NCSA
12436 back-compatibility [Robert Thau]
12438 *) Mutual exclusion around accept() is on by default for SVR4 systems
12439 generally, since they generally can't handle multiple processes in
12440 accept() on the same socket. This should cure flaky behavior on
12441 a lot of those systems. [David Robinson]
12443 *) AddType, AddEncoding, and AddLanguage directives take multiple
12444 extensions on a single command line [David Robinson]
12446 *) UserDir can be disabled for a given virtual host by saying
12447 "UserDir disabled" in the <VirtualHost> section --- it was a bug
12448 that this didn't work. [David Robinson]
12450 *) Compiles on QNX [Ben Laurie]
12452 *) Corrected parsing of ctime time format [David Robinson]
12454 *) httpd does a perror() before exiting if it can't log its pid
12455 to the PidFile, to make diagnosing the error a bit easier.
12458 *) <!--#include file="..."--> can no longer include files in the
12459 parent directory, for NCSA back-compatibility. [David Robinson]
12461 *) '~' is *not* escaped in URIs generated for directory listings
12464 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
12466 *) Fixed bug involving handling URIs with escaped %-characters
12467 in redirects [David Robinson]
12469 Changes with Apache 0.8.15 14 Oct 1995
12471 *) Switched to new, simpler license
12473 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
12475 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
12477 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
12479 *) Correctly handles internal redirects to files with names containing '%'
12482 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
12484 *) Use geteuid() rather than getuid() to see if we have root privilege,
12485 so that server correctly resets privilege if run setuid root. [Andrew
12488 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
12491 *) Fix relative URLs in imagemap files [Randy Terbush]
12493 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
12496 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
12497 entries all name the same one. [David Robinson]
12499 *) Fix directory listings with filenames containing unusual characters
12502 *) Better URI-escaping for generated URIs in directories with filenames
12503 containing unusual characters [Ben Laurie]
12505 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
12507 *) Unblock alarms on error return from spawn_child() [David Robinson]
12509 *) Sample Config files have extra note for SCO users [Ben Laurie]
12511 *) Configuration has note for HP-UX users [Rob Hartill]
12513 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
12515 *) Nuked bogus #define in httpd.h [David Robinson]
12517 *) Better test for whether a system has setrlimit() [David Robinson]
12519 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
12521 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
12524 Changes with Apache 0.8.14 19 Sep 1995
12526 *) Compiles on SCO ODT 3.0 [Ben Laurie]
12528 *) AddDescription works (better) [Ben Laurie]
12530 *) Leaves an intelligible error diagnostic when it can't set group
12531 privileges on standalone startup [Andrew Wilson]
12533 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
12534 that machine, which claims to be BSD but does not support RLIMIT.
12537 *) gcc -Wall no longer complains about an unused variable when util.c
12538 is compiled with -DMINIMAL_DNS [Andrew Wilson]
12540 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
12542 Changes with Apache 0.8.13 07 Sep 1995
12544 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
12546 *) Have built-in imagemap code recognize & honor Point directive [James
12549 *) Generate cleaner directory listings in directories with a mix of
12550 long and short filenames [Rob Hartill]
12552 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
12554 *) Properly default ServerName for virtual servers [Robert Thau]
12556 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
12557 Paul Richards and a cast of thousands...]
12559 *) On self-identified BSD systems (we don't try to guess any more),
12560 allocate a few extra file descriptors per virtual host with setrlimit,
12561 if we can, to avoid running out. [Randy Terbush]
12563 *) Write 22-character lock file name into buffer with enough space
12564 on startup [Konstantin Olchanski]
12566 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
12569 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
12571 *) Suppress -Wall warning by initializing variable in negotiation code
12572 [Tobias Weingartner]
12574 Changes with Apache 0.8.12 31 Aug 1995
12576 *) Doesn't pause three seconds after including a CGI script which is
12577 too slow to die off (this is done by not even trying to kill off
12578 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
12579 after the entire document has been processed). [Robert Thau]
12581 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
12583 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
12585 *) Allows .htaccess files to override <Directory> sections naming the
12586 same directory [David Robinson]
12588 *) Removed an efficiency hack in sub_req_lookup_uri which was
12589 causing certain extremely marginal cases (e.g., ScriptAlias of a
12590 *particular* index.html file) to fail. [David Robinson]
12592 *) Doesn't log an error when the requested URI requires
12593 authentication, but no auth header line was supplied by the
12594 client; this is a normal condition (the client doesn't no auth is
12595 needed here yet). [Robert Thau]
12597 *) Behaves more sanely when the name server loses its mind [Sean Welch]
12599 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
12601 *) RFC931 code no longer passes out name of prior clients on current
12602 requests if the current request came from a server that doesn't
12603 do RFC931. [David Robinson]
12605 *) Configuration script accepts "Module" lines with trailing whitespace.
12608 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
12610 *) Cleaned up comments in mod_cgi.c [Robert Thau]
12612 Changes with Apache 0.8.11 24 Aug 1995
12614 *) Wildcard <Directory> specifications work. [Robert Thau]
12616 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
12618 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
12619 the file being requested itself, in addition to the directories leading
12620 up to it. [Robert Thau]
12622 *) Logs access failures due to symlink checks or invalid client address
12623 in the error log [Roy Fielding, Robert Thau]
12625 *) Symlink checks deal correctly with systems where lstat of
12626 "/path/to/some/link/" follows the link. [Thau, Fielding]
12628 *) Doesn't reset DirectoryIndex to 'index.html' when
12629 other directory options are set in a .htaccess file. [Robert Thau]
12631 *) Clarified init code and nuked bogus warning in mod_access.c
12632 [Florent Guillaume]
12634 *) Corrected several directives in sample srm.conf
12635 --- includes corrections to directory indexing icon-related directives
12636 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
12637 icons for encodings right, and turning on AddEncoding by default).
12640 *) Corrected descriptions of args to AddIcon and AddAlt in command table
12643 *) INSTALL & README mention "contributed modules" directory [Brian
12646 *) Fixed English in the license language... "for for" --> "for".
12649 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
12650 mod_alias.c, merging it almost completely with handling of Alias, and
12651 adding a 'notes' field to the request_rec which allows the CGI module
12652 to discover whether the Alias module has put this request through
12653 ScriptAlias (which it needs to know for back-compatibility, as the old
12654 NCSA code did not check Options ExecCGI in ScriptAlias directories).
12657 Changes with Apache 0.8.10 18 Aug 1995
12659 *) AllowOverride applies to the named directory, and not just
12660 subdirectories. [David Robinson]
12662 *) Do locking for accept() exclusion (on systems that need it)
12663 using a special file created for the purpose in /usr/tmp, and
12664 not the error log; using the error log causes real problems
12665 if it's NFS-mounted; this is known to be the cause of a whole
12666 lot of "server hang" problems with Solaris. [David Robinson;
12667 thanks to Merten Schumann for help diagnosing the problem].
12669 Changes with Apache 0.8.9 12 Aug 1995
12671 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
12673 *) Nested includes see environment variables of the including document,
12674 for NCSA bug-compatibility (some sites have standard footer includes
12675 which try to print out the last-modified date). [Eric Hagberg/Robert
12678 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
12679 URI as a CGI script, even if it would have been treated as something
12680 else if requested directly, for NCSA back-compatibility. (Note that
12681 this means that people who know the name of the script can see the
12682 code just by asking for it). [Robert Thau]
12684 *) New version of dbmmanage script included in support directory as
12687 *) Check if scoreboard file couldn't be opened, and say so, rather
12688 then going insane [David Robinson]
12690 *) POST to CGI works on A/UX [Jim Jagielski]
12692 *) AddIcon and AddAlt commands work properly [Rob Hartill]
12694 *) NCSA server push works properly --- the Arena bug compatibility
12695 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
12696 if you still want the workaround). [Rob Hartill]
12698 *) If client didn't submit any Accept-encodings, ignore encodings in
12699 content negotiation. (NB this will all have to be reworked anyway
12700 for the new HTTP draft). [Florent Guillaume]
12702 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
12704 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
12706 *) Give Redirect priority over Alias, for NCSA bug compatibility
12709 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
12710 paralleling earlier bug fix for CGI [David Robinson]
12712 *) If DBM auth is improperly configured, report a server error and don't
12715 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
12716 it seems to work well enough without it (even in a 10 hits/sec
12717 workout), and the overhead for the locking under A/UX is
12718 alarmingly high (though it is very low on other systems).
12719 [Eric Hagberg, Jim Jagielski]
12721 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
12723 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
12724 Behlendorf/Eric Hagberg]
12726 *) More improvements to default Configuration for A/UX [Jim Jagielski]
12728 *) Compiles clean on NEXT [Rob Hartill]
12730 *) Compiles clean on SGI [Robert Thau]
12732 Changes with Apache 0.8.8 08 Aug 1995
12734 *) SunOS library prototypes now never included unless explicitly
12735 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
12736 people using GNU libc on SunOS are screwed by prototypes for the
12739 (Those who wish to compile clean with gcc -Wall on a standard
12740 SunOS setup need the prototypes, and may obtain them using
12741 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
12742 with nonstandard libraries are presumably competent to make their
12745 *) Strips trailing '/' characters off both args to the Alias command,
12746 to make 'Alias /foo/ /bar/' work.
12748 Changes with Apache 0.8.7 03 Aug 1995
12750 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
12751 [reported by David Robinson]
12753 *) Compiles clean on OSF/1 [David Robinson]
12755 *) Added some of the more recent significant changes (AddLanguage stuff,
12756 experimental LogFormat support) to CHANGES file in distribution root
12759 Changes with Apache 0.8.6 02 Aug 1995
12761 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
12762 (If you actually wanted a conditional GET which bypassed the cache, you
12763 couldn't get it). [Reported by Roy Fielding]
12765 *) Properly terminate headers on '304 Not Modified' replies to conditional
12766 GETs --- no browser we can find cares much, but the CERN proxy chokes.
12767 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
12769 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
12771 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
12772 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
12773 and older versions don't set the __SUNPRO_C preprocessor variable). On
12774 all other systems, these are never used anyway. [Reported by Mark Cox].
12776 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
12778 Changes with Apache 0.8.5 01 Aug 1995
12780 *) Added last-minute configurable log experiment, as optional module
12782 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
12783 properly. (One-line fix to http_protocol.c).
12785 *) Work around bogus behavior when reloading from Netscape.
12786 It's Netscape's bug --- for some reason they expect a request with
12787 If-modified-since: to not function as a conditional GET if it also
12788 comes with Pragma: no-cache, which is way out of line with the HTTP
12789 spec (according to Roy Fielding, the redactor).
12791 *) Added parameter to set maximum number of server processes.
12793 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
12796 *) IdentityCheck bugfix [Chuck Murcko].
12798 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
12800 *) More sample config file corrections; add extension to AddType for
12801 *.asis, move AddType generic description to its proper place, and
12802 fix miscellaneous typos. [ Alexei Kosut ]
12804 *) Deleted the *other* reference to the regents from the Berkeley
12805 legal disclaimer (everyplace).
12807 *) Nuked Shambhala name from src/README; had already cleaned it out
12808 of everywhere else.
12810 Changes with Apache 0.8.4
12812 *) Changes to server-pool management parms --- renamed current
12813 StartServers to MinSpareServers, created separate StartServers
12814 parameter which means what it says, and renamed MaxServers to
12815 MaxSpareServers (though the old name still works, for NCSA 1.4
12816 back-compatibility). The old names were generally regarded as
12817 too confusing. Also altered "docs" in sample config files.
12819 *) More improvements to default config files ---
12820 sample directives (commented out) for XBitHack, BindAddress,
12821 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
12822 defaults, AddTypes for send-as-is and imagemap magic types, and
12823 improvements to samples for DirectoryIndex [Alexei Kosut]
12825 *) Yet more improvements to default config files --- changes to
12826 Alexei's sample AddLanguage directives, and sample LanguagePriority
12827 [ Florent Guillaume ]
12829 *) Set config file locations properly if not set in httpd.conf
12832 *) Don't escape URIs in internal redirects multiple times; don't
12833 do that when translating PATH_INFO to PATH_TRANSLATED either.
12836 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
12838 Changes with Apache 0.8.3
12840 *) Edited distribution README to *briefly* summarize installation
12841 procedures, and give a pointer to the INSTALL file in the src/
12844 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
12845 recent NCSA distributions.
12847 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
12848 exist for the same directory, use both and don't segfault. [Reported
12851 *) Proper makefile dependencies [David Robinson]
12853 *) Note (re)starts in error log --- reported by Rob Hartill.
12855 *) Only call no2slash() after get_path_info() has been done, to
12856 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
12857 reported by Andrew Wilson, though this one is probably a real bug]
12859 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
12860 dump core when Referer is not supplied. [Randy Terbush]
12862 *) Lightly edited sample config files to refer people to our documentation
12863 instead of NCSA's, and to list Rob McCool as *original* author (also
12864 deleted his old, and no doubt non-functional email address). Would be
12865 nice to have examples of new features...
12867 Changes with Apache 0.8.2 19 Jul 1995
12869 *) Added AddLanuage code [Florent Guillaume]
12871 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
12873 *) All sorts of problems when MultiViews finds a directory. It would
12874 be nice if mod_dir.c was robust enough to handle that, but for now,
12875 just punt. [reported by Brian Behlendorf]
12877 *) Wait for all children on restart, to make sure that the old socket
12878 is gone and we can reopen it. [reported by Randy Terbush]
12880 *) Imagemap module is enabled in default Configuration
12882 *) RefererLog and UserAgentLog modules properly default the logfile
12885 *) Mark Cox's mod_cookies added to the distribution as an optional
12886 module (commented out in the default Configuration, and noted as
12887 an experiment, along with mod_dld). [Mark Cox]
12889 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
12891 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
12893 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
12895 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
12898 Changes with Apache 0.8.1
12900 *) New imagemap module [Randy Terbush]
12902 *) Replacement referer log module with NCSA-compatible RefererIgnore
12903 [Matthew Gray again]
12905 *) Don't mung directory listings with very long filenames.
12906 [Florent Guillaume]
12908 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
12910 *) New config script. See INSTALL for info. [Robert Thau]
12912 *) Scoreboard mechanism for regulating the number of extant server
12913 processes. MaxServers and StartServers defaults are the same as
12914 for NCSA, but the meanings are slightly different. (Actually,
12915 I should probably lower the MaxServers default to 10).
12917 Before asking for a new connection, each server process checks
12918 the number of other servers which are also waiting for a
12919 connection. If there are more than MaxServers, it quietly dies
12920 off. Conversely, every second, the root, or caretaker, process
12921 looks to see how many servers are waiting for a new connection;
12922 if there are fewer than StartServers, it starts a new one. This
12923 does not depend on the number of server processes already extant.
12924 The accounting is arranged through a "scoreboard" file, named
12925 /tmp/htstatus.*, on which each process has an independent file
12926 descriptor (they need to seek without interference).
12928 The end effect is that MaxServers is the maximum number of
12929 servers on an *inactive* server machine, but more will be forked
12930 off to handle unusually heavy loads (or unusually slow clients);
12931 these will die off when they are no longer needed --- without
12932 reverting to the overhead of full forking operation. There is a
12933 hard maximum of 150 server processes compiled in, largely to
12934 avoid forking out of control and dragging the machine down.
12935 (This is arguably too high).
12937 In my server endurance tests, this mechanism did not appear to
12938 impose any significant overhead, even after I forced it to put the
12939 scoreboard file on a normal filesystem (which might have more
12940 overhead than tmpfs). [Robert Thau]
12942 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
12945 *) Read .htaccess files even in directory with <Directory> section.
12946 (Former incompatibility noted on mailing list, now fixed). [Robert
12949 *) "HEAD /" gives the client a "Bad Request" error message, rather
12950 than trying to send no body *and* no headers. [Cliff Skolnick].
12952 *) Don't produce double error reports for some very obscure cases
12953 mainly involving auth configuration (the "all modules decline to
12954 handle" case which is a sure sign of a server bug in most cases,
12955 but also happens when authentication is badly misconfigured).
12958 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
12959 it's *for*, and this sort of thing really shouldn't be cluttering
12960 up the Makefile). [Robert Thau]
12962 *) Incidental code cleanups in http_main.c --- stop dragging
12963 sa_client around; just declare it where used. [Robert Thau]
12965 *) Another acc-related fix. (It doesn't like const char
12966 in some places...). [Mark Cox]
12968 Changes with Shambhala 0.6.1 13 Jul 1995
12970 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
12971 Also, fixed auth typo in http_protocol.c unmasked by this fix.
12973 *) Compiles clean with acc on SunOS [Paul Sutton]
12975 *) Reordered modules in modules.c so that Redirect takes priority
12976 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
12977 believe it or not, he has an actual site with a ScriptAlias and
12978 a Redirect declared for the *exact same directory*. Even *my*
12979 compatibility fetish wouldn't motivate me to fix this if the fix
12980 required any effort, but it doesn't, so what the hey.
12982 *) Fixed to properly default several server_rec fields for virtual
12983 servers from the corresponding fields in the main server_rec.
12984 [Cliff Skolnick --- 'port' was a particular irritant].
12986 *) No longer kills off nph- child processes before they are
12987 finished sending output. [Matthew Gray]
12989 Changes with Shambhala 0.6.0 10 Jul 1995
12991 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
12992 the connection to the client in an "aborted" state, but otherwise
12993 allow whatever handlers are running to clean up. hard_timeout()s
12994 abort the request in progress completely; anything not tied to some
12995 resource pool cleanup will leak. They're still around because I
12996 haven't yet come up with a more elegant way of handling
12997 timeouts when talking to something that isn't the client. The
12998 default_handler and the dir_handler now use soft timeouts, largely
12999 so I can test the feature. [Robert Thau]
13001 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
13002 the case of log handlers dying prematurely is probably handled VERY
13003 gracelessly at this point, and if the logger stops reading input,
13004 the server will hang. (It is known to correctly restart the
13005 logging process on server restart; this is (should be!) going through
13006 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
13007 script). [Robert Thau]
13009 *) asis files supported (new module). [Robert Thau]
13011 *) IdentityCheck code is compiled in, but has not been tested. (I
13012 don't know anyone who runs identd). [Robert Thau]
13014 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
13015 came in with the request, for NCSA bug-compatibility. [Robert Thau]
13017 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
13019 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
13020 as timeouts are not in scope. [Robert Thau]
13022 *) quoted-string args in config files now handled correctly (doesn't drop
13023 the last character). [Robert Thau; reported by Randy Terbush]
13025 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
13026 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
13028 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
13029 default default type); the former default default behavior when all
13030 type-checkers defaulted had been a core dump. [Paul Sutton]
13032 *) Copy filenames out of the struct dirent when indexing
13033 directories. (On Linux, readdir() returns a pointer to the same
13034 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
13036 Changes with Shambhala 0.5.3 [not released]
13038 *) Default response handler notes "file not found" in the error log,
13039 if the file was not found. [Cliff Skolnick].
13041 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
13042 code no longer sets up bogus PATH_INFO which fakes out the directory
13043 handler). [Cliff Skolnick]
13045 Changes with Shambhala 0.5.2 06 Jul 1995
13047 *) Changes to http_main.c --- root server no longer plays silly
13048 games with SIGCHLD, and so now detects and replaces dying
13049 children. Child processes just die on SIGTERM, without taking
13050 the whole process group with them. Potential problem --- if any
13051 child process refuses to die, we hang in restart.
13052 MaxRequestsPerChild may still not work, but it certainly works
13053 better than it did before this! [Robert Thau]
13055 *) mod_dir.c bug fixes: ReadmeName and HeaderName
13056 work (or work better, at least); over-long description lines
13057 properly terminated. [Mark Cox]
13059 *) http_request.c now calls unescape_url() more places where it
13060 should [Paul Sutton].
13062 *) More directory handling bugs (reported by Cox)
13063 Parent Directory link is now set correctly. [Robert Thau]
13065 Changes with Shambhala 0.5.1 04 Jul 1995
13067 *) Generalized cleanup interface in alloc.c --- any function can be
13068 registered with alloc.c as a cleanup for a resource pool;
13069 tracking of files and file descriptors has been reimplemented in
13070 terms of this interface, so I can give it some sort of a test.
13073 *) More changes in alloc.c --- new cleanup_for_exec() function,
13074 which tracks down and closes all file descriptors which have been
13075 registered with the alloc.c machinery before the server exec()s a
13076 child process for CGI or <!--#exec-->. CGI children now get
13077 started with exactly three file descriptors open. Hopefully,
13078 this cures the problem Rob H. was having with overly persistent
13079 CGI connections. [Robert Thau]
13081 *) Mutual exclusion around the accept() in child_main() --- this is
13082 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
13083 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
13084 This uses fcntl(F_SETLK,...) on the error log descriptor because
13085 flock() on that descriptor won't work on systems which have BSD
13086 flock() semantics, including (I think) Linux 1.3 and Solaris.
13088 This does work on SunOS (when the server is idle, only one
13089 process in the pool is waiting on accept()); it *ought* to work
13090 on the other systems. [Robert Thau]
13092 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
13094 *) sizeof(*sa_client) bugfix from [Rob Hartill]
13096 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
13098 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
13099 be unnecessary if I go to the revised timeout-handling scheme).
13102 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
13103 string) even if none came in with the request. [Robert Thau]
13105 *) CHANGES file added to distribution ;-).
13107 Changes with Shambhala 0.4.5
13109 *) mod_dld --- early dynamic loading support [rst]
13110 *) Add wildcard content handlers for XBITHACK; default_hander now
13111 invoked with that mechanism (as a handler hanging off mod_core) [rst]
13112 *) XBITHACK supported as a wildcard content-handler, and
13113 configurable at run-time (not just at compile time, as in the
13114 "patchy server" releases) [rst]
13116 Changes with Shambhala 0.4.4 30 Jun 1995
13118 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
13119 *) Handle Addtype x/y .z [rst, reported by Cox]
13121 Changes with Shambhala 0.4.3
13123 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
13124 synonymous [rst, terbush]
13126 Changes with Shambhala 0.4.1 28 Jun 1995
13128 *) First-cut virtual host implementation; some refit in the config
13129 reading code, and log management, was necessary to support this [rst]
13130 *) Sub-pool machinery, originally added to avoid excessive storage
13131 allocation on listings of large directories (which turned out to
13132 be the problem that the 0.3 storage accounting was added to
13133 find). Subrequests and mod_dir changed to use subpools. [rst]
13134 *) More memory debugging --- free list consistency checks. [rst]
13135 *) Added err_headers to request_rec, with support elsewhere [rst]
13136 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
13138 Changes with Shambhala 0.3 19 Jun 1995
13140 *) Switch ONE_PROCESS to a runtime command-line option (-X)
13141 *) Don't compile in mod_ai_backcompat by default
13142 *) Switch name of server from Apache to Shambhala in Makefile
13143 *) Add some accounting routines to track memory usage in the pools,
13146 Changes with Shambhala 0.2
13148 *) Set DOCUMENT_ROOT CGI variable
13149 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
13150 *) Add critical section protection to handling of cleanup structures
13152 *) Significant code reorg within the server core to group related
13153 functions together [rst]
13154 *) Correctly handle clients that hang up before sending any request
13156 *) Replace dying child processes. [rst]
13158 Changes with Shambhala 0.1 12 Jun 1995
13160 Major rewrite of the pre-existing "patchy server" codebase, by
13161 Robert Thau (rst). Significant portions of the server code, such
13162 as configuration-file handling and HTTP authentication support,
13163 were ripped out and rewritten from scratch. Code that was not
13164 completely rewritten was significantly altered.
13166 Major changes with this release include:
13168 *) Introduction of the module API; in request handling, the central
13169 machinery just dispatches to various modules, which actually do
13170 most of the work. Configuration handling is similar --- modules
13171 declare their own commands, and the central machinery just
13172 dispatches to them.
13174 API features from shambhala/0.1 were substantially unchanged in
13175 Apache 1.0 and 1.1. (1.0 API features not yet present in this
13176 release, such as wildcard handlers and subpools, were added in
13177 subsequent Shambhala releases, and were also generally rst's
13180 *) This release included the following modules:
13182 mod_access (access control --- allow and deny directives),
13183 mod_alias (Alias and Redirect commands),
13184 mod_auth (straight HTTP authentication, based on flat-files)
13185 mod_auth_dbm (same, with dbm files)
13186 mod_cgi (CGI scripts and, in this release, ScriptAlias)
13187 mod_common_log (CLF access logs; later renamed mod_log_common)
13188 mod_dir (directory indexing)
13189 mod_include (server-side includes)
13190 mod_mime (AddType directives)
13191 mod_negotiation (content negotiation)
13192 mod_userdir (support for users' public_html directories)
13194 It also included a mod_ai_backcompat, which was a private hack
13195 for back-compatibility with rst's own AI-lab servers.
13197 All of these modules were substantially complete, and functional
13198 or nearly so (a few, which implemented features not in use at
13199 Thau's site, required patches of a few lines).
13201 *) sub-request machinery, to allow modules to determine how other
13202 modules would assign MIME types to a given file, or optionally
13203 serve its content (this is heavily used by mod_dir, mod_include
13204 and mod_negotiation).
13206 *) Resource pool system for keeping track of memory allocated and
13207 files opened in service of a particular request. Much of the
13208 code in the modules (when they weren't rewrites) was adjusted to
13209 replace a pervasive convention of using fixed-size buffers on
13210 the stack with an equally pervasive convention of using memory
13211 allocated with palloc().
13213 *) Reorganization of data structures associated with a given
13214 request to eliminate use of global variables and the troublesome
13215 unmunge_name function (used in NCSA and early Apache releases to
13216 attempt to determine the URI which mapped to a given filename
13217 --- a difficult proposition, given that it is easy to produce
13218 setups in which multiple URIs map to the same file).
13220 *) Source files renamed and rearranged
13222 *) Very simple pre-forking behavior --- parent process forked off a
13223 fixed number of children, and then just waited for SIGHUP.
13225 *) Other more minor changes too numerous to list.
13227 This release included modified versions of a lot of code from the
13228 Apache 0.6.4 public release, plus an early pre-forking patch
13229 codeveloped by Robert Thau and Rob Hartill.
13231 Changes with Apache 0.7.3 20 Jun 1995
13233 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
13234 were incorporated by Rob Hartill on the main branch while Robert Thau
13235 worked on the Shambhala rewrite above. Most were merged into the
13236 Shambala architecture after Apache 0.8.0.
13238 Changes with Apache 0.6.4 13 May 1995
13240 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
13243 Changes with Apache 0.5.1 10 Apr 1995
13245 Changes with Apache 0.4 02 Apr 1995
13247 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
13250 Changes with Apache 0.3 24 Mar 1995
13252 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
13255 Changes with Apache 0.2 18 Mar 1995
13257 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
13258 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
13259 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
