1 Changes with Apache 2.1.0-dev
3 [Remove entries to the current 2.0 section below, when backported]
5 *) SECURITY [CAN-2003-0020]: Escape arbitrary data before writing
6 into the errorlog. [André Malo]
8 *) mod_expires: Initialize ExpiresDefault to NULL instead of "" to
9 avoid reporting an Internal Server error if it is used without
10 having been set in the httpd.conf file. PR: 23748, 24459
11 [Andre Malo, Liam Quinn <liam htmlhelp.com>]
13 *) mod_logio: Account for some bytes handed to the network layer prior to
14 dropped connections. [Jeff Trawick]
16 *) Fix a problem with the display of empty variables ("SetEnv foo") in
17 mod_include. PR 24734 [Markus Julen <mj zermatt.net>]
19 *) Win32 MPM: The bucket brigades subsystem now honors the MaxMemFree setting.
22 *) mod_autoindex: new directive IndexStyleSheet
23 [Tyler Riddle <triddle_1999 yahoo.com>, Paul Querna <chip force-elite.com>]
25 *) Fix a long delay with CGI requests and keepalive connections on
28 *) Fix uninitialized gprof directory name in prefork MPM. PR 24450.
29 [Chris Knight <Christopher.D.Knight nasa.gov>]
31 *) mod_auth_ldap: Fix some segfaults in the cache logic. PR 18756.
32 [Matthieu Estrade <apache moresecurity.org>]
34 *) mod_autoindex: Restore the ability to add a description for
35 directories that don't contain an index file. [André Malo]
37 *) mod_autoindex: Add 'XHTML' option in order to allow switching between
38 HTML 3.2 and XHTML 1.0 output. PR 23747. [André Malo]
40 *) Add XHTML Document Type Definitions to httpd.h (minor MMN bump).
43 *) mod_setenvif: Fix the regex optimizer, which under circumstances
44 treated the supplied regex as literal string. PR 24219.
47 *) mod_autoindex / core: Don't fail to show filenames containing
48 special characters like '%'. PR 13598. [André Malo]
50 *) mod_info: HTML escape configuration information so it displays
51 correctly. PR 24232. [Thom May]
53 *) mod_status: Report total CPU time accurately when using a threaded
54 MPM. PR 23795. [Jeff Trawick]

59 *) Log an error when requests for URIs which fail to map to a valid
60 filesystem name are rejected with 403. [Jeff Trawick]
62 *) Fix a couple of AIX xlc_r compiler issues in the code I just
63 committed. [Paul J. Reder]
65 *) Modified the cache code to be header-location agnostic. Also
66 fixed a number of other cache code bugs related to PR 15852.
67 Includes a patch submitted by Sushma Rai <rsushma novell.com>.
68 This fixes mod_mem_cache but not mod_disk_cache yet so I'm not
69 closing the PR since that is what they are using. [Paul J. Reder]
71 *) Switch to APR 1.0 API.
73 *) Fix mod_include's expression parser to recognize strings correctly
74 even if they start with an escaped token. [André Malo]
76 *) Major overhaul of mod_include's filter parser. The new parser code
77 is expected to be more robust and should catch all of the edge cases
78 that were not handled by the previous one. This includes a binary
79 incompatible change of mod_include's external API. [André Malo]
81 *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
82 PR 14223. [André Malo]

85 could lead to a 400 (Bad Request) response. [André Malo]
87 *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously
88 the current rewrite state was just used as lookup path, which lead to
89 strange and often useless results. Related to PR 8493. [André Malo]

97 *) Fix a link failure in mod_ssl when the OpenSSL libraries contain
98 the ENGINE functions but the engine header files are missing.
101 *) mod_dav: Use bucket brigades when reading PUT data. This avoids
102 problems if the data stream is modified by an input filter. PR 22104.
103 [Tim Robbins <tim robbins.dropbear.id.au>, André Malo]
105 *) mod_rewrite: RewriteRules in server context using the force
106 type feature [T=...] no longer disable MultiViews. [André Malo]
108 *) mod_rewrite: In external rewrite maps lookup keys containing
109 a newline now cause a lookup failure. PR 14453.
110 [Cedric Gavage <cedric.gavage unixtech.be>, André Malo]
112 *) mod_rewrite: Allow piped rewrite logs to be relative to ServerRoot.
115 *) mod_authz_groupfile: Strip trailing spaces of group names. This
116 hopefully saves some hours of searching for typos. PR 12863.
119 *) mod_actions: Propagate the handler name to the action script via
120 the REDIRECT_HANDLER environment variable. [André Malo]
122 *) mod_actions: Introduce the "virtual" modifier to the Action directive,
123 which allows the use of handlers for virtual locations. PR 8431.
126 *) mod_speling: Recognize AcceptPathInfo setting for the particular
127 location. Default is to reject path information. PR 21059.
130 *) mod_ext_filter: Add the ability to filter request bodies.
131 [Philipp Reisner <philipp.reisner linbit.com>]
133 *) mod_cgid: Restart the cgid daemon if it crashes. PR 19849
134 [Glenn Nielsen <glenn apache.org>]
136 *) Fix some broken log messages in WinNT MPM.
137 [Juan Rivera <Juan.Rivera citrix.com>]
139 *) Add support for IMT minor-type wildcards (e.g., text/*) to
140 ExpiresByType. PR#7991 [Ken Coar]
142 *) Fix a problem with namespace mappings being dropped in mod_dav_fs;
143 if any property values were set which defined namespaces these
144 came out mangled in the PROPFIND response. PR 11637.
145 [Amit Athavale <amit_athavale persistent.co.in>]
147 *) prefork MPM: Use the right permissions for the directory created
148 for gprof support. [Jim Carlson <jcarlson jnous.com>]
150 *) Fix a compile failure with recent OpenSSL and picky compilers
151 (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
153 *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
154 the INCLUDE path to be defined properly.
155 PR 11310. [Geoff Thorpe <geoff geoffthorpe.net>]
157 *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
159 *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
160 autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc).
161 [Geoff Thorpe <geoff geoffthorpe.net>]
163 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
164 [Ian Holsman, André Malo]
166 *) mod_negotiation: quality values are now parsed independent from
167 the current locale. level values are now really parsed as integers.
168 PR 17564. [André Malo]
170 *) Added the WindowsSocketsWorkaround directive for Windows NT/2000/XP
171 to work around problems with certain VPN and Firewall products that
172 have buggy AcceptEx implementations.
173 [Allan Edwards w/ suggestions from Bill Stoddard & Bill Rowe]
175 *) Extend mod_negotiation to evaluate the environment variables
176 no-gzip and gzip-only-text/html the same way as mod_deflate does.
179 *) mod_rewrite: Fix some problems reporting errors with mapping
180 programs (RewriteMap prg:/something). [Jeff Trawick]
182 *) Return 413 if chunk-ext-header is too long rather than reading from
183 the truncated line. PR 15857. [Justin Erenkrantz]
185 *) Allow restart of httpd to occur even with syntax errors in the config
186 file. PR 16813. [Justin Erenkrantz]

200 *) mod_log_config change optional hook to return previous handler
203 *) Forward port of mod_actions' ability to handle arbitrary methods
204 with the Script directive. [André Malo]
206 *) Let suexec send a message to stderr, if it failed or its policy
207 was violated. This message appears in the error log and allows
208 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
210 *) Modify buildconf to copy all required files into httpd's tree.
211 [Thom May <thom planetarytramp.net>]
213 *) Allow mod_dav to do weak entity comparison functions.
216 *) Move RFC 1413 ident requests from core to new module mod_ident.
219 *) Add mod_authz_owner - a forward port of "Require file-owner"
220 and "Require file-group", which was already present in version
223 *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
226 *) Replace some of the mutex locking in the worker MPM with
227 atomic operations for higher concurrency. [Brian Pane]
229 *) Allow 'make depend' to work with non-GCC compilers.
232 *) If an httpd.conf has commented out AddModule directives,
233 apxs -i -a will add an un-commented AddModule directive for
234 the new module, which breaks the config.
235 PR: 11212 [Joe Orton]
237 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
239 *) Move the check of the Expect request header field after the hook
240 for ap_post_read_request, since that is the only opportunity for
241 modules to handle Expect extensions. [Justin Erenkrantz]
243 *) Rewrite of aaa modules to an authn/authz model.
244 [Dirk-Willem van Gulik, Justin Erenkrantz]
247 [Apache 2.1.0-dev includes those bug fixes and changes with the

256 PR 19355. [Geoffrey Young <geoff apache.org>, André Malo]
258 *) EBCDIC: Convert header fields to ASCII before sending (broken
259 since 2.0.44). [Martin Kraemer]
261 *) Fix the inability to log errors like exec failure in
262 mod_ext_filter/mod_cgi script children. This was broken after
263 such children stopped inheriting the error log handle.
266 *) Fix mod_info to use the real config file name, not the default
267 config file name. [Aryeh Katz <aryeh secured-services.com>]
269 *) Set the scoreboard state to indicate logging prior to running
270 logging hooks so that server-status will show 'L' for hung loggers
271 instead of 'W'. [Jeff Trawick]
273 Changes with Apache 2.0.48
275 *) SECURITY [CAN-2003-0789]: mod_cgid: Resolve some mishandling of
276 the AF_UNIX socket used to communicate with the cgid daemon and
277 the CGI script. [Jeff Trawick]
279 *) SECURITY [CAN-2003-0542]: Fix buffer overflows in mod_alias and
280 mod_rewrite which occurred if one configured a regular expression
281 with more than 9 captures. [André Malo]
283 *) mod_include: fix segfault which occured if the filename was not
284 set, for example, when processing some error conditions.
285 PR 23836. [Brian Akins <bakins web.turner.com>, André Malo]
287 *) fix the config parser to support <Foo>..</Foo> containers (no
288 arguments in the opening tag) supported by httpd 1.3. Without
289 this change mod_perl 2.0's <Perl> sections are broken.
290 ["Philippe M. Chiasson" <gozer cpan.org>]
292 *) mod_cgid: fix a hash table corruption problem which could
293 result in the wrong script being cleaned up at the end of a
294 request. [Jeff Trawick]
296 *) Update httpd-*.conf to be clearer in describing the connection
297 between AddType and AddEncoding for defining the meaning of
298 compressed file extensions. [Roy Fielding]
300 *) mod_rewrite: Don't die silently when failing to open RewriteLogs.
301 PR 23416. [André Malo]
303 *) mod_rewrite: Fix mod_rewrite's support of the [P] option to send
304 rewritten request using "proxy:". The code was adding multiple "proxy:"
305 fields in the rewritten URI. PR: 13946.
306 [Eider Oliveira <eider bol.com.br>]
308 *) cache_util: Fix ap_check_cache_freshness to check max_age, smax_age, and
309 expires as directed in RFC 2616. [Thomas Castelle <tcastelle generali.fr>]
311 *) Ensure that ssl-std.conf is generated at configure time, and switch
312 to using the expanded config variables to work the same as
313 httpd-std.conf PR: 19611
316 *) mod_ssl: Fix segfaults after renegotiation failure. PR 21370
317 [Hartmut Keil <Hartmut.Keil adnovum.ch>]
319 *) mod_autoindex: If a directory contains a file listed in the
320 DirectoryIndex directive, the folder icon is no longer replaced
321 by the icon of that file. PR 9587.
322 [David Shane Holden <dpejesh yahoo.com>]
324 *) Fixed mod_usertrack to not get false positive matches on the
325 user-tracking cookie's name. PR 16661.
326 [Manni Wood <manniwood planet-save.com>]
328 *) mod_cache: Fix the cache code so that responses can be cached
329 if they have an Expires header but no Etag or Last-Modified
333 *) mod_log_config: Fix %b log format to write really "-" when 0 bytes
334 were sent (e.g. with 304 or 204 response codes). [Astrid Keßler]
336 *) Modify ap_get_client_block() to note if it has seen EOS.
339 *) Fix a bug, where mod_deflate sometimes unconditionally compressed the
340 content if the Accept-Encoding header contained only other tokens than
341 "gzip" (such as "deflate"). PR 21523. [Joe Orton, André Malo]
343 *) Avoid an infinite recursion, which occured if the name of an included
344 config file or directory contained a wildcard character. PR 22194.

357 MaxClients has to be lowered due to the setting of ServerLimit.
360 *) Lower the severity of the "listener thread didn't exit" message
361 to debug, as it is of interest only to developers. PR 9011
364 *) MPMs: The bucket brigades subsystem now honors the MaxMemFree setting.
365 [Cliff Woolley, Jean-Jacques Clar]
367 *) Install config.nice into the build/ directory to make
368 minor version upgrades easier. [Joshua Slive]
370 *) Fix mod_deflate so that it does not call deflate() without checking
371 first whether it has something to deflate. (Currently this causes
372 deflate to generate a fatal error according to the zlib spec.)
373 PR 22259. [Stas Bekman]
375 *) mod_ssl: Fix FakeBasicAuth for subrequest. Log an error when an
376 identity spoof is encountered.
379 *) mod_rewrite: Ignore RewriteRules in .htaccess files if the directory
380 containing the .htaccess file is requested without a trailing slash.
381 PR 20195. [André Malo]
383 *) ab: Overlong credentials given via command line no longer clobber
384 the buffer. [André Malo]
386 *) mod_deflate: Don't attempt to hold all of the response until we're
387 done. [Justin Erenkrantz]

401 to scripts using the REDIRECT_REMOTE_USER environment variable.
402 PR 10678, 11602. [André Malo]
404 *) mod_include: Fix a trio of bugs that would cause various unusual
405 sequences of parsed bytes to omit portions of the output stream.
406 PR 21095. [Ron Park <ronald.park cnet.com>, André Malo, Cliff Woolley]
408 *) Update the header token parsing code to allow LWS between the
409 token word and the ':' seperator. [PR 16520]

419 response. PR 21085. [Glenn Nielsen <glenn apache.org>, André Malo]
421 *) mod_rewrite: Perform child initialization on the rewrite log lock.
422 This fixes a log corruption issue when flock-based serialization
423 is used (e.g., FreeBSD). [Jeff Trawick]
425 *) Don't respect the Server header field as set by modules and CGIs.
426 As with 1.3, for proxy requests any such field is from the origin
427 server; otherwise it will have our server info as controlled by
428 the ServerTokens directive. [Jeff Trawick]
430 Changes with Apache 2.0.47
432 *) SECURITY [CAN-2003-0192]: Fixed a bug whereby certain sequences
433 of per-directory renegotiations and the SSLCipherSuite directive
434 being used to upgrade from a weak ciphersuite to a strong one
435 could result in the weak ciphersuite being used in place of the
436 strong one. [Ben Laurie]
438 *) SECURITY [CAN-2003-0253]: Fixed a bug in prefork MPM causing
439 temporary denial of service when accept() on a rarely accessed port
440 returns certain errors. Reported by Saheed Akhtar
441 <S.Akhtar talis.com>. [Jeff Trawick]
443 *) SECURITY [CAN-2003-0254]: Fixed a bug in ftp proxy causing denial
444 of service when target host is IPv6 but proxy server can't create
445 IPv6 socket. Fixed by the reporter. [Yoshioka Tsuneo
446 <tsuneo.yoshioka f-secure.com>]
448 *) SECURITY [VU#379828] Prevent the server from crashing when entering
449 infinite loops. The new LimitInternalRecursion directive configures
450 limits of subsequent internal redirects and nested subrequests, after
451 which the request will be aborted. PR 19753 (and probably others).
452 [William Rowe, Jeff Trawick, André Malo]
454 *) core_output_filter: don't split the brigade after a FLUSH bucket if
455 it's the last bucket. This prevents creating unneccessary empty
456 brigades which may not be destroyed until the end of a keepalive
458 [Juan Rivera <Juan.Rivera citrix.com>]
460 *) Add support for "streamy" PROPFIND responses.
461 [Ben Collins-Sussman <sussman collab.net>]
463 *) mod_cgid: Eliminate a double-close of a socket. This resolves
464 various operational problems in a threaded MPM, since on the
465 second attempt to close the socket, the same descriptor was
466 often already in use by another thread for another purpose.
469 *) mod_negotiation: Introduce "prefer-language" environment variable,
470 which allows to influence the negotiation process on request basis
471 to prefer a certain language. [André Malo]
473 *) Make mod_expires' ExpiresByType work properly, including for
474 dynamically-generated documents. [Ken Coar, Bill Stoddard]
476 Changes with Apache 2.0.46
478 *) SECURITY [CAN-2003-0245]: Fixed a bug causing apr_pvsprintf() to crash
479 by sending an overly long string. This can be triggered remotely
480 through mod_dav, mod_ssl, and other mechanisms. Reported by David
481 Endler <DEndler iDefense.com>.
482 [Joe Orton <jorton redhat.com>]
484 *) SECURITY [CAN-2003-0189]: Fixed a denial-of-service vulnerability
485 affecting basic authentication on Unix platforms related to
486 thread-safety in apr_password_validate(). The problem was reported
487 by John Hughes <john.hughes entegrity.com>.
489 *) Fix for mod_dav. Call the 'can_be_activity' callback, if provided,
490 when a MKACTIVITY request comes in.
491 [Ben Collins-Sussman <sussman collab.net>]
493 *) Perform run-time query in apxs for apr and apr-util's includes.
496 *) run libtool from the apr install directory (in case that is different
497 from the apache install directory) [Jeff Trawick]
499 *) configure.in: Play nice with libtool-1.5. [Wilfredo Sanchez]
501 *) If mod_mime_magic does not know the content-type, do not attempt to
502 guess. PR 16908. [Andrew Gapon <agapon telcordia.com>]
504 *) ssl session caching(shmht) : Fix a SEGV problem with SHMHT session
506 [Andreas Leimbacher <andreasl67 yahoo.de>, Madhusudan Mathihalli]
508 *) Add a delete flag to htpasswd.
511 *) Fix mod_rewrite's handling of absolute URIs. The escaping routines
512 now work scheme dependent and the query string will only be
513 appended if supported by the particular scheme. [André Malo]
515 *) Add another check for already compressed content in mod_deflate.
516 PR 19913. [Tsuyoshi SASAMOTO <nazonazo super.win.ne.jp>]
518 *) Fixes for VPATH builds; copying special.mk and any future .mk files
519 from the source tree as well as the build tree (now creates a usable
520 configuration for apxs), and eliminated redundant -I'nclude paths.
523 *) Code fixes, constness corrections and ssl_toolkit_compat.h updates
524 for SSLC and OpenSSL toolkit compatibility. Still work remains to
525 be done to cripple features based on the limitations of RSA's binary
526 distribution of their SSL-C toolkit.
527 [William Rowe, Madhusudan Mathihalli, Jeff Trawick]
529 *) Linux 2.4+: If Apache is started as root and you code
530 CoreDumpDirectory, coredumps are enabled via the prctl() syscall.
533 *) ap_get_mime_headers_core: allocate space for the trailing null
534 when folding is in effect.
535 PR 18170 [Peter Mayne <PeterMayne SPAM_SUX.ap.spherion.com>]
537 *) Fix --enable-mods-shared=most and other variants. [Aaron Bannert]
539 *) mod_log_config: Add the ability to log the id of the thread
540 processing the request via new %P formats. [Jeff Trawick]
542 *) Use appropriate language codes for Czech (cs) and Traditional Chinese
543 (zh-tw) in default config files. PR 9427. [André Malo]
545 *) mod_auth_ldap: Use generic whitespace character class when parsing
546 "require" directives, instead of literal spaces only. PR 17135.
549 *) Hook mod_rewrite's type checker before mod_mime's one. That way the
550 RewriteRule [T=...] Flag should work as expected now. PR 19626.
553 *) htpasswd: Check the processed file on validity. If a line is not empty
554 and not a comment, it must contain at least one colon. Otherwise exit
555 with error code 7. [Kris Verbeeck <Kris.Verbeeck ubizen.com>, Thom May]
557 *) Fix a problem that caused httpd to be linked with incorrect flags
558 on some platforms when mod_so was enabled by default, breaking
559 DSOs on AIX. PR 19012 [Jeff Trawick]
561 *) By default, use the same CC and CPP with which APR was built.
562 The user can override with CC and CPP environment variables.
565 *) Fix ap_construct_url() so that it surrounds IPv6 literal address
566 strings with []. This fixes certain types of redirection.
567 PR 19207. [Jeff Trawick]
569 *) forward port of buffer overflow fixes for htdigest. [Thom May]
571 *) Added AllowEncodedSlashes directive to permit control of whether
572 the server will accept encoded slashes ('%2f') in the URI path.
573 Default condition is off (the historical behaviour). This permits
574 environments in which the path-info needs to contain encoded
575 slashes. PR 543, 2389, 3581, 3589, 5687, 7066, 7865, 14639. [Ken Coar]
577 *) When using Redirect in directory context, append requested query
578 string if there's no one supplied by configuration. PR 10961.
581 *) Unescape the supplied wildcard pattern in mod_autoindex. Otherwise
582 the pattern will not always match as desired. PR 12596.
585 *) mod_autoindex now emits and accepts modern query string parameter
586 delimiters (;). Thus column headers no longer contain unescaped
587 ampersands. PR 10880 [André Malo]

1160 and remove the noise on stderr during config dir processing.
1161 [Joe Orton <jorton redhat.com>]
1163 *) mod_cache: cache_storage.c. Add the hostname and any request
1164 args to the key generated for caching. This provides a unique
1165 key for each virtual host and for each request with unique
1166 args. [Paul J. Reder, args code provided by Kris Verbeeck]
1168 *) mod_cache: Do not cache responses to GET requests with query
1169 URLs if the origin server does not explicitly provide an
1170 Expires header on the response (RFC 2616 Section 13.9)

1206 *) mod_rewrite can now sets cookies in err_headers, uses the correct
1207 expiry date, and can now set the path as well
1208 PR 12132,12181,12172.
1209 [Ian Holsman / Rob Cromwell <apachechangelog robcromwell.com>]
1211 *) The content-length filter no longer tries to buffer up
1212 the entire output of a long-running request before sending
1213 anything to the client. [Brian Pane]
1215 *) Win32: Lower the default stack size from 1MB to 256K. This will
1216 allow around 8000 threads to be started per child process.
1217 'EDITBIN /STACK:size apache.exe' can be used to change this
1218 value directly in the apache.exe executable.
1221 *) Win32: Implement ThreadLimit directive in the Windows MPM.
1224 *) Remove CacheOn config directive since it is set but never checked.
1225 No sense wasting cycles on unused code. Besides, the only truly
1226 bug free code is deleted code. :) [Paul J. Reder]
1228 *) BufferLogs are now run-time enabled, and the log_config now has 2 new
1229 callbacks to allow a 3rd party module to actually do the writing of the
1230 log file [Ian Holsman]
1232 *) Correct ISAPIReadAheadBuffer to default to 49152, per mod_isapi docs.

1241 *) New option to ServerTokens 'maj[or]'. Only show the major version
1242 Also Surfaced this directive in the standard config (default FULL)
1245 *) Change mod_rewrite to use apr-util's dbm support for dbm rewrite
1246 maps. The dbm type (e.g., ndbm, gdbm) can be specified on the
1247 RewriteMap directive. PR 10644 [Jeff Trawick]
1249 *) Fixed mod_rewrite's RewriteMap prg: support so that request/response

1259 *) Fix bug where environment or command line arguments containing
1260 non-ASCII-7 characters would cause the Win32 child process creation
1261 to fail. PR 11854 [William Rowe]
1263 *) Bug #11213.. make module loading error messages more informative
1264 [Ian Darwin <Ian779 darwinsys.com>]
1266 *) thread safety & proxy-ftp [Alexey Panchenko <alexey liwest.ru>, Ian Holsman]
1268 *) mod_disk_cache works much better. This module should still
1269 be considered experimental. [Eric Prud'hommeaux]
1271 *) Performance improvement for keepalive requests: when setting
1272 aside a small file for potential concatenation with the next
1273 response on the connection, set aside the file descriptor rather
1274 than copying the file into the heap. [Brian Pane]
1276 *) Modified version check on openssl so that it finds the executable
1277 first and then performs a check of the version, only warning the
1278 user if they chose, or we selected, an old version of OpenSSL.
1279 This change also allows the code to work for non-openssl libraries
1280 selected via the --with-ssl=dir option, which can override the
1281 automated library check in any case. [Roy Fielding]
1283 Changes with Apache 2.0.40
1285 *) SECURITY [CAN-2002-0661] (cve.mitre.org):
1286 Close a very significant security hole that
1287 applies only to the Win32, OS2 and Netware platforms. Unix was not
1288 affected, Cygwin may be affected. Certain URIs will bypass security
1289 and allow users to invoke or access any file depending on the system
1290 configuration. Without upgrading, a single .conf change will close
1291 the vulnerability. Add the following directive in the global server
1292 httpd.conf context before any other Alias or Redirect directives;
1293 RedirectMatch 400 "\\\.\."
1294 Reported by Auriemma Luigi <bugtest sitoverde.com>.
1297 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1298 Close a path-revealing exposure in multiview type
1299 map negotiation (such as the default error documents) where the
1300 module would report the full path of the typemapped .var file when
1301 multiple documents or no documents could be served based on the mime
1302 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
1305 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1306 Close a path-revealing exposure in cgi/cgid when we
1307 fail to invoke a script. The modules would report "couldn't create
1308 child process /path-to-script/script.pl" revealing the full path
1309 of the script. Reported by Jim Race <jrace qualys.com>.
1312 *) Set aside the apr-iconv and apr_xlate() features for the Win32
1313 build of 2.0.40 so development can be completed. A patch, from
1314 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
1315 will be available for those that wish to work with apr-iconv.
1318 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
1319 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
1321 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
1322 set to 1, so we can exclude things from the general case with
1323 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
1325 *) Accept multiple leading /'s for requests within the DocumentRoot.
1326 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
1328 *) Solved the reports of .pdf byterange failures on Win32 alone.
1329 APR's sendfile for the win32 platform collapses header and trailer
1330 buffers into a single buffer. However, we destroyed the pointers
1331 to the header buffer if a trailer buffer was present. PR 10781
1334 *) mod_ext_filter: Add the ability to enable or disable a filter via
1335 an environment variable. Add the ability to register a filter of
1336 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
1338 *) Restore the ability to specify host names on Listen directives.
1339 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh yahoo.com>]
1341 *) When deciding on the default address family for listening sockets,
1342 make sure we can actually bind to an AF_INET6 socket before
1343 deciding that we should default to AF_INET6. This fixes a startup
1344 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
1346 *) Replace usage of atol() to parse strings when we might want a
1347 larger-than-long value with apr_atoll(), which returns long long.
1348 This allows HTTPD to deal with larger files correctly.
1349 [Shantonu Sen <ssen apple.com>]
1351 *) mod_ext_filter: Ignore any content-type parameters when checking if
1352 the response should be filtered. Previously, "intype=text/html"
1353 wouldn't match something like "text/html;charset=8859_1".
1356 *) mod_ext_filter: Set up environment variables for external programs.
1357 [Craig Sebenik <craig netapp.com>]
1359 *) Modified the HTTP_IN filter to immediately append the EOS (end of
1360 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
1361 the caller to determine that no content remains without prefetching
1362 additional POST body. [William Rowe]
1364 *) Get proxy ftp to work over IPv6. [Shoichi Sakane <sakane kame.net>]
1366 *) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml suse.de>]
1368 *) Update SuSE layout. [Peter Poeml <poeml suse.de>]
1370 *) Changes to the internationalized error documents:
1371 Comment them out in the default config file to make the default
1372 install as simple as possible; Correct the english 500 error to
1373 be more understandable; Add a Swedish translation.
1374 [Thomas Sjogren <thomas northernsecurity.net>,
1375 Erik Abele <erik codefaktor.de>, Rich Bowen, Joshua Slive]
1377 *) Increase the limit on file descriptors per process in apachectl.
1380 *) Fix a dependency error when building ApacheMonitor, so that Win32
1381 and MSVC now trust that the project is current (when it is).
1382 [James Cox <imajes php.net>]
1384 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
1385 [Arthur P. Smith <apsmith aps.org>, Jeff Trawick]
1387 *) APR-Util Renames pending have been completed [Thom May]
1389 *) Performance improvements for the code that reads request
1390 headers (ap_rgetline_core() and related functions) [Brian Pane]
1392 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
1393 to configure the maximum amount of memory the allocators will
1394 hold on to for reuse. Anything over the MaxMemFree threshold
1395 will be free()d. This directive is useful when uncommon large
1396 peaks occur in memory usage. It should _not_ be used to mask
1397 defective modules' memory use. [Sander Striker]
1399 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
1400 scripts would not result in a truncated response.
1401 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
1403 *) Add a filter_init parameter to the filter registration functions
1404 so that a filter can execute arbitrary code before the handlers
1405 are invoked. This resolves a problem where mod_include requests
1406 would incorrectly return a 304. [Justin Erenkrantz]
1408 *) Fix a long-standing bug in 2.0, CGI scripts were being called
1409 with relative paths instead of absolute paths. Apache 1.3 used
1410 absolute paths for everything except for SuExec, this brings back
1411 that standard. [Ryan Bloom]
1413 *) Fix infinite loop due to two HTTP_IN filters being present for
1414 internally redirected requests. PR 10146. [Justin Erenkrantz]
1416 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
1419 *) Fix mod_ext_filter to look in the main server for filter definitions
1420 when running in a vhost if the filter definition is not found in
1421 the vhost. PR 10147 [Jeff Trawick]
1423 *) Support WinNT CGI invocation through ScriptInterpreterSource
1424 'registry' for script interpreter paths and names with non-ascii
1425 characters in the executable filepath. [William Rowe]
1427 *) Support the -w flag on to keep the Win32 console open on error.
1430 *) Normalize the hostname value in the request_rec to all-lowercase
1431 [Perry Harrington <pedward webcom.com>]
1433 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
1434 extended characters (non US-ASCII) in non-utf8 format. This brings
1435 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
1436 to the cgi application itself. [William Rowe]
1438 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
1439 modules to bring them up to the current apr/apr-util APIs.
1442 *) Fix segfault in mod_mem_cache most frequently observed when
1443 serving the same file to multiple clients on an MP machine.
1446 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
1447 [Brian Degenhardt <bmd mp3.com>, Ian Holsman]
1449 *) Fix perchild to work with apachectl by adding -k support to perchild.
1450 PR 10074 [Jeff Trawick]
1452 *) Fix a silly htpasswd.c logic error that incorrectly reported that
1453 both -c and -n had been used. PR 9989 [Cliff Woolley]
1455 *) Fixed a mod_include error case in which no HTTP response was sent
1456 to the client if an shtml document contained an unterminated SSI
1457 directive [Brian Pane]
1459 *) Improve ap_get_client_block implementation by using APR-util brigade
1460 helper functions and relying on current filter assumptions.
1463 Changes with Apache 2.0.39
1465 *) Fixed a build problem in htpasswd.c on Win32.
1466 [Guenter Knauf <eflash gmx.net>, Cliff Woolley]
1468 Changes with Apache 2.0.38
1470 *) Rewrite htpasswd to use APR. The removes the annoying warning about
1471 tmpnam being unsafe. [Ryan Bloom]
1473 *) We must set the MIME-type for .shtml files to text/html if we want them
1474 to be parsed for SSI tags. Add the config for that to the default
1475 config file so that it is easier to enable .shtml parsing.
1476 [Dave Dyer <ddyer real-me.net>]
1478 *) Fixed a problem with 'make install' on ReliantUnix.
1479 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
1481 *) Make the default_handler catch all requests that aren't served by
1482 another handler. This also gets us to return a 404 if a directory
1483 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1484 loaded. [Justin Erenkrantz]
1486 *) Fixed the handling of nested if-statements in shtml files.
1487 PR 9866 [Brian Pane]
1489 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1490 into a directory different from the one that was configured. This
1491 also mirrors the root= feature from 1.3. We cannot use prefix=,
1492 because both APR and APR-util resolve their installation paths at
1493 configuration time. This means that there is no variable prefix
1494 to replace. [Andreas Hasenack <andreas netbank.com.br>]
1496 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1497 These levels of AIX don't have a thundering herd problem with
1498 accept(). [Jeff Trawick]
1500 *) prefork MPM: Ignore mutex errors during graceful restart. For
1501 certain types of mutexes (particularly SysV semaphores), we
1502 should expect to occasionally fail to obtain or release the
1503 mutex during restart processing. [Jeff Trawick]
1505 *) Fix install-bindist.sh so that it finds any perl instead of just
1506 early perl 5.x versions. This is consistent with a build/install
1507 from source, and it allows the perl scripts installed by a bindist
1508 to work on systems with perl 5.6. [Jeff Trawick]
1510 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
1511 Tru64 (and probably some other platforms). [Jeff Trawick]
1513 *) Allow CGI scripts to return their Content-Length. This also fixes a
1514 hang on HEAD requests seen on certain platforms (such as FreeBSD).
1517 *) Added log rotation based on file size to the RotateLog support
1518 utility. [Brad Nicholes]
1520 *) Fix some casting in mod_rewrite which broke random maps.
1521 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
1523 Changes with Apache 2.0.37
1525 *) allow POST method over SSL when per-directory client cert
1526 authentication is used with 'SSLOptions +OptRenegotiate' enabled
1527 and a client cert was found in the ssl session cache.
1529 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
1530 session cache when there is no cert chain in the cache. prior to
1531 the fix this situation would result in a FORBIDDEN response and
1532 error message "Cannot find peer certificate chain"
1535 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
1536 one was already sent. PR 9644 [Jeff Trawick]
1538 *) Fix the display of the default name for the mime types config
1539 file. PR 9729 [Matthew Brecknell <mbrecknell orchestream.com>]

1543 of Apache.exe, in the case that Apache.exe resides in bin/.)
1544 Solves the case of ServerRoot /foo paths where /foo was not
1545 on the same drive as /winnt/system32. [William Rowe]
1547 *) Make 2.0's "AcceptMutex" startup message now "completely"
1548 match how 1.3 does it. [Jim Jagielski]
1550 *) Implement a fixed size memory cache using a priority queue
1553 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
1554 querying certain other variables from config_vars.mk. PR 9316
1557 *) Added the "detached" attribute to the cgi_exec_info_t internals
1558 so that Win32 and Netware won't create a new window or console
1559 for each CGI invoked. PR 8387
1560 [Brad Nicholes, William Rowe]
1562 *) Consolidated the command line parameters and attributes that are
1563 manipulated by the optional function ap_cgi_build_command() in
1564 mod_cgi into a single structure.
1567 *) Get rid of uninitialized value errors with "apxs -q" on certain
1568 variables. [Stas Bekman <stas stason.org>]
1570 *) Fix apxs to allow it to work when the build directory is somewhere
1571 besides server-root/build. PR 8453
1572 [Jeff Trawick and a host of others]
1574 *) Allow ap_discard_request_body to be called multiple times in the
1575 same request. Essentially, ap_http_filter keeps track of whether
1576 it has sent an EOS bucket up the stack, if so, it will only ever
1577 send an EOS bucket for this request.
1578 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
1580 *) Remove all special mod_ssl URIs. This also fixes the bug where
1581 redirecting (.*) will allow an SSL protected page to be viewed
1582 without SSL. [Ryan Bloom]
1584 *) Fix the binary build install script so that the build logic
1585 created by "apxs -g" will work when the user has a binary
1586 build. [Jeff Trawick]
1588 *) Allow instdso.sh to work with full paths to the shared module.
1591 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
1592 in module for NetWare [Brad Nicholes]
1594 *) Changed cgi and piped log behavior to accept 65536 characters
1595 on Win32 (matching Linux) before deadlocking between outputing
1596 client stdin, slurping the output from stdout and then the stderr
1597 stream. PR 8179 [William Rowe]
1599 *) Fixed Win32 wintty.exe support to assure the window title is valid.
1600 Elimiates possible gpfault or garbage title without the -t option.
1603 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
1604 brigades and input filters. [Justin Erenkrantz]
1606 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
1607 body. [Justin Erenkrantz]
1609 *) NetWare: Piping log entries through RotateLogs using the
1610 CustomLogs directive is finally supported now that we have

1629 *) Ensure that apr_brigade_write() flushes in all of the cases that
1630 it should to avoid conditions in some modules that could cause
1631 large amounts of data to be buffered. [Cliff Woolley]
1633 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
1634 stripping the content_type from cached responses.
1637 *) apachectl passes through any httpd options. Note: apachectl
1638 should be used in preference to httpd since it ensures that any
1639 appropriate environment variables have been set up.

1798 - Allow whitespace between the pipe and the name of the
1799 program in SSLLog "| /path/to/program". [Cliff Woolley]

1870 explicitly tell the server that warning messages should be sent
1871 to the client in addition to being recorded in the error log.
1872 Prior to this change, ap_log_rerror() always sent warning
1873 messages to the client. In one case, a faulty CGI script caused
1874 the server to send a warning message to the client that contained
1875 the full path to the CGI script. This could be considered a
1876 minor security exposure. [Bill Stoddard]
1878 *) mod_autoindex output when SuppressRules was specified would

1892 *) Change instdso.sh to use libtool --install everywhere and then
1893 clean up some stray files and symlinks that libtool leaves around
1894 on some platforms. This gets subversion building properly since
1895 it needed a re-link to be performed by libtool at install time,

1908 *) Fix segfault in mod_mem_cache when garabge collecting an expired
1909 cache entry. [Bill Stoddard]
1911 *) Introduced -E startup_logfile_name option to httpd to allow admins
1912 to begin logging errors immediately. This provides Win32 users
1913 an alternative to sending startup errors to the event viewer, and

2003 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
2004 cause the Apache parent process to run in the foreground (similar to
2005 -DNO_DETACH except that it doesn't switch session ids).
2008 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
2009 for those platforms that support it. If using the default
2010 implementation, this is between pthread and sysvsem in priority.
2011 This implies it's the new default for Darwin. [Jim Jagielski]
2013 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
2014 environment variables in the envvars file. [Jeff Trawick]
2016 *) worker MPM: Don't create a listener thread until we have a worker

2052 removed. This does not affect scoreboards which are *mapped* to
2053 files using named-shared-memory. [Jim Jagielski]
2055 *) Change bucket brigades API to allow a "bucket allocator" to be

2096 *) Fix a mod_cgid problem that left daemon processes stranded
2097 in some server restart scenarios. [Jeff Trawick]
2099 *) Added exp_foo and rel_foo variables to config_vars.mk for
2100 all Apache and Autoconf path variables (like --sysconfdir,
2101 --sbindir, etc). exp_foo is the "expanded" version, which means
2102 that all internal variable references have been interpolated.
2103 rel_foo is the same as $exp_foo, only relative to $prefix if they
2104 share a common path. [Aaron Bannert]
2106 *) Fix some restart/terminate problems in the worker MPM. Don't
2107 drop connections during graceful restart. [Jeff Trawick]

2195 *) Modify receive/send loop in proxy_http and proxy_ftp so that
2196 should it be necessary, the remote server socket is closed before
2197 transmitting the last buffer (set by ProxyIOBufferSize) to the
2198 client. This prevents the backend server from being forced to hang
2199 around while the last few bytes are transmitted to a slow client.
2200 Fix the case where no error checking was performed on the final
2201 brigade in the loop. [Graham Leggett]

2242 this allows mod_ssl to be added to a server that is already
2243 running and makes it possible to add/change certs/keys after the

2268 cruft in piped logs and rewritemap child processes.
2271 *) All instances of apr_lock_t have been removed and converted
2272 to one of the following new lock APIs: apr_thread_mutex.h,
2273 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
2274 use the apr_lock.h API, as the old API will soon be deprecated.
2277 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
2278 [Ralf S. Engelschall, Cliff Woolley]
2280 *) mod-include: make it handle flush'es and fix the 'false-alarm'
2281 [Justin Erenkrantz, Brian Pane, Ian Holsman]
2283 *) ap_get_*_filter_handle() functions to allow 3rd party modules
2284 to lookup filter handles so they can bypass the filter name
2285 lookup when adding filters to a request (via ap_add_*_filter_handle())
2286 [Ryan Morgan <rmorgan covalent.net>]
2288 *) Fix for multiple file buckets on Win32, where the first file
2289 bucket would cause the immediate closure of the socket on any
2290 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
2292 *) Correct Win32 failure of mmap of a segment beyond start of the
2293 file; fixes large SSL and similar transfers. [William Rowe]
2296 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
2297 multi-process mode to not "daemonize" while detaching from the
2298 controlling terminal. This is necessary for Apache to work with
2299 process-management tools like AIX's "System Resource Controller"
2300 as well as Dan Bernstein's "daemontools".
2301 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
2303 *) Convert mod_auth_digest to use the new apr_global_mutex_t
2304 type. [Aaron Bannert]
2306 *) fix bug in mod-include where it wouldn't send a unmatched
2307 part if it was at the end of a bucket [Ian Holsman]
2309 *) worker MPM: Improve logging of errors with the interface between
2310 the listener thread and worker threads. [Jeff Trawick]
2312 *) Some browsers ignore cookies that have been merged into a
2313 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
2314 are now unmerged in the http proxy before being sent to the
2315 client. [Graham Leggett]
2317 *) Fix a problem with proxy where each entry of a duplicated
2318 header such as Set-Cookie would overwrite and obliterate the
2319 previous value of the header, resulting in multiple header
2320 values (like cookies) going missing.
2321 [Graham Leggett, Joshua Slive]
2323 *) Add the server-limit and thread-limit values to the scoreboard
2324 for the sake of third-party applications.
2325 [Adam Sussman <myddryn vishnu.vidya.com>]
2327 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
2329 *) OS/390: Get make install to properly copy DSO modules.
2332 *) Win32: Fix bug in mod_status with displaying "Restart Time"
2333 and "Server uptime".
2336 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
2338 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
2340 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
2341 [David MacKenzie <djm pix.net>]
2343 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
2344 [David MacKenzie <djm pix.net>]
2346 *) Fix segfault and display error when SSLMutex file can not be
2347 created. [Adam Sussman <myddryn vishnu.vidya.com>]
2349 *) Add reference counting to mod_mem_cache cache objects to
2350 better manage removing objects from the cache.
2353 *) Change the verbage on the ScoreBoardFile in our default configs.
2354 Also change the default to be commented out (unspecified) so we
2355 get anonymous shared memory by default. [Aaron Bannert]
2357 *) Implement new ScoreBoardFile directive logic. This affects how
2358 we create the scoreboard's shared memory segment. If the directive
2359 is present, a name-based segment is created. If the directive is
2360 not present, first an anonymous segment is created, and if that
2361 fails, a name-based segment is created from a file of the name
2362 DEFAULT_SCOREBOARD. This gives third-party applications the
2363 ability to access our scoreboard. [Aaron Bannert]
2365 *) Allow mod_deflate to work with non-GET requests and properly send
2366 Content-Lengths. [Sander Striker <striker apache.org>]
2368 *) Fix ap_directory_merge() to correctly merge configs when there is
2369 no <Directory /> block. [Justin Erenkrantz, William Rowe]
2371 *) Remove spurious debug messsages that are normal under HTTP
2372 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
2374 *) Fix a bug in mod_cgid that would prevent proper shutdown death
2375 of the cgid process. [Aaron Bannert]
2377 *) Add signal handling back in to the worker MPM for the one_process
2378 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
2380 *) Performance: Reuse per-connection transaction pools in the
2381 worker MPM, rather than destroying and recreating them. [Brian Pane]
2383 *) Remove all signals from the worker MPM's child process. Instead,
2384 the parent uses the Pipe of Death for all communication with the
2385 child processes. [Ryan Bloom]
2387 Changes with Apache 2.0.32
2389 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
2390 default if the directive is not specified. This mirrors older
2391 behavior without changes to the httpd.conf. [William Rowe]
2393 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
2394 the service, mpm and logging code, and bugs in apr_file_open_stderr
2395 and apr_file_dup2 functions. Win2K/XP services have no handles
2396 associated for stdin/out/err, which caused unpredictable behavior
2397 in the prior release. [William Rowe, Bill Stoddard]
2399 *) Win32: simplify the Application Event Log messages, since there isn't
2400 likely to be 'more information in the error log' before an error log
2401 has been opened. [William Rowe]
2403 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
2404 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
2406 *) Win32: apache -k shutdown now behaves like apache -k stop.
2409 *) Fix prefork to not kill the parent if a child hits a resource shortage
2410 on accept(). [Greg Ames]
2412 *) Fix seg faults that occur when what should be the httpd request line
2413 starts with \r\n followed by garbage. [Greg Ames]
2415 *) Allow statically linked support binaries with the new
2416 --enable-static-support flag, and enable this behavior in
2417 the binbuild script. Also add a new --enable-static-htdbm
2418 flag. [Aaron Bannert]
2420 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
2421 do only one stat() call when generating the directory listings.
2424 *) Fix resolve_symlink to save the original symlink name if known.
2427 *) Be a bit more sane with regard to CanonicalNames. If the user has
2428 specified they want to use the CanonicalName, but they have not
2429 configured a port with the ServerName, then use the same port that
2430 the original request used. [Ryan Bloom and Ken Coar]
2432 *) In core_input_filter, check for an empty brigade after
2433 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
2434 client says it will post some data but we get FIN before any
2435 data arrives. [Jeff Trawick]
2437 *) Not being able to bind to the socket is a fatal error. We should
2438 print an error to the console, and return a non-zero status code.
2439 With these changes, all of the Unix MPMs do that correctly.
2442 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
2443 through to CGI scripts. PR 9163
2444 [Brian Reid <breid customlogic.com>,
2445 Zvi Har'El <rl math.technion.ac.il>]
2447 *) binbuild.sh: Make sure that we use the expat from our source
2448 tree so that there aren't any surprises on the target machine.
2451 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2452 enough to keep up with new requests. Start using
2453 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2454 when we can't talk to the daemon. [Jeff Trawick]
2456 *) apxs: LTFLAGS envvar can override default libtool options. Try
2457 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2458 the covers. [Jeff Trawick]
2460 *) The Location: response header field, used for external
2461 redirect, *must* be an absoluteURI. The Redirect directive
2462 tested for that, but RedirectMatch didn't -- it would allow
2463 almost anything through. Now it will try to turn an abs_path
2464 into an absoluteURI, but it will correctly varf like Redirect
2465 if the final redirection target isn't an absoluteURI. [Ken Coar]
2467 Changes with Apache 2.0.31
2469 *) Create the scoreboard (in the parent) in a global pool context,
2470 so it survives graceful restarts. This fixes a SEGV during
2471 graceful restarts. [Aaron Bannert]
2473 *) Add a timeout option to the proxy code 'ProxyTimeout'
2476 *) FTP directory listings are now always retrieved in ASCII mode.
2477 The FTP proxy properly escapes URI's and HTML in the generated
2478 listing, and escapes the path components when talking to the FTP
2479 server. It is now possible to browse the root directory by using
2480 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2481 Also, the last path component may contain wildcard characters
2482 '*' and '?', and if they do, a directory listing is created instead
2483 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2486 *) Added single-listener unserialized accept support to the
2487 worker MPM [Brian Pane]
2489 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2490 the incoming host header through to the proxied server
2491 [Geoff <g.russell ieee.org>]
2493 *) New Directive Option for ProxyPass. It now can block a location
2494 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
2496 *) Don't let the default handler try to serve a raw directory. At
2497 best you get gibberish. Much worse things can happen depending
2498 on the OS. [Jeff Trawick]
2500 *) Change the pre_config hook to return a value. Modules can now emit
2501 an error message and then cause the server to quit gracefully during
2502 startup. This required a bump to the MMN. [Aaron Bannert]
2504 *) Fix some unix socket descriptor leaks in the handler side of
2505 mod_cgid (the part that runs in the server process). Whack a
2506 silly "close(-1)" in the handler too. [Jeff Trawick]
2508 *) Change the pre_mpm hook to return a value, so that scoreboard
2509 init errors percolate up to code that knows how to exit
2510 cleanly. This required a bump to the MMN. [Jeff Trawick]
2512 *) Add the socket back to the conn_rec and remove the create_connection
2513 hook. The create_connection hook had a design flaw that did not
2514 allow creating connections based on vhost info. [Bill Stoddard]
2516 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2517 Resolves the common case of using negotation to resolve the request
2518 /script/foo for /script.cgi/foo. [William Rowe]
2520 *) Added new functions ap_add_(input|output)_filter_handle to
2521 allow modules to bypass the usual filter name lookup when
2522 adding hard-coded filters to a request [Brian Pane]
2524 *) caching should now work on subrequests (still very experimental)
2527 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2529 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2532 *) Refactor ap_rgetline so that it does not use an internal brigade.
2533 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2535 *) Remove mod_auth_db. [Justin Erenkrantz]
2537 *) Do not install unnecessary pcre headers like config.h and internal.h.
2538 [Joe Orton <joe manyfish.co.uk>]
2540 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
2541 (as it does for a normal request). quick_handled sub-requests now work
2542 in mod-include [Ian Holsman]
2544 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
2545 'CONTENT' one, as it needs to run AFTER all content headers
2547 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
2550 *) Split out blocking from the mode in the input filters.
2553 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
2555 *) Cause Win32 to capture all child-worker process errors in
2556 Apache to the main server error log, until the child can
2557 open its own error logs. [William Rowe]
2559 *) HPUX 11.*: Do not kill the child process when accept()
2560 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
2561 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
2563 *) Fix a problem in the parsing of the <Proxy foo> directive.
2566 *) rewrite of mod_ssl input filter for better performance and less
2567 memory usage [Doug MacEachern]
2569 *) allow quick_handler to be run on subrequests. [Ian Holsman]
2571 *) mod_dav now asks its provider to place content directly into the
2572 filter stack when handling a GET request. The mod_dav/provider
2573 API has changed, so providers need to be updated. [Greg Stein]
2575 *) Clear the output socket descriptor in unixd_accept() to make sure
2576 we don't supply a bogus socket to the caller if the accept fails.
2577 This caused problems with the worker MPM, which tried to process
2578 the returned socket if it was non-NULL. [Brian Pane]
2580 *) Move a check for an empty brigade to the start of core input filter
2581 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
2583 *) Add FileETag directive to allow configurable control of what
2584 data are used to form ETag values for file-based URIs. MMN
2585 bumped to 20020111 because of fields added to the end of
2586 the core_dir_config structure. [Ken Coar]
2588 *) Fix a segfault in mod_rewrite's logging code caused by passing the
2589 wrong config to ap_get_remote_host(). [Jeff Trawick]
2591 *) Allow mod_cgid to work from a binary distribution install by
2592 using 755 for the permissions on the log directory instead of
2595 *) Fixed a segfault that happened during graceful shutdown (or when
2596 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
2598 *) Split all Win32 modules [excluding the core components mod_core,
2599 mod_so, mod_win32 and the winnt mpm] into individual loadable
2600 modules, so the administrator may individually disable the former
2601 compiled-in modules by simply commenting out their LoadModule
2602 directives. [William Rowe]
2604 *) Saved Win32 module authors and porters many future headaches, by
2605 duplicating the appropriate .h files such as os.h into the include
2606 directory, including in the build tree. [William Rowe]
2608 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
2609 Use SSL functions/macros instead of directly dereferencing SSL
2610 structures wherever possible.
2611 Add type-casts for the cases where functions return a generic pointer.
2612 Add $SSL/include to configure search path.
2613 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
2615 *) Moved several pointers out of the shared Scoreboard so it is
2616 more portable, and will present the vhost name across server
2617 generation restarts. [William Rowe]
2619 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
2622 Changes with Apache 2.0.30
2624 *) Fix the main bug for FreeBSD and threaded MPM's. There are
2625 still issues (see STATUS) but at least the server will now
2626 run without crashing the machine.
2627 [David Reid, Aaron Bannert, Justin Erenkrantz]
2629 *) Fix a typo in mod_deflate's m4 config section.
2630 [albert chin <china thewrittenword.com>]
2632 *) Fix a couple of mod_proxy problems forwarding HTTP connections
2633 and handling CONNECT:
2634 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
2635 (2) Proxy failed to connect when the first IP address returned by
2636 the resolver was unreachable but a secondary IP address was.
2639 *) Fix the module identifer as shown in the docs for various core
2640 modules (e.g., the identifer for mod_log_config was previously
2641 listed as config_log_module). PR #9338
2642 [James Watson <ap2bug sowega.org>]
2644 *) Fix LimitRequestBody directive by placing it in the HTTP
2645 filter. [Justin Erenkrantz]
2647 *) Fix mod_proxy seg fault when the proxied server returns
2648 an HTTP/0.9 response or a bogus status line.
2651 *) Prevent mod_proxy from truncating one character off the
2652 end of the status line returned from the proxied server.
2653 [Adam Sussman, Bill Stoddard]
2655 *) Eliminate loop in ap_proxy_string_read().
2656 [Adam Sussman, Bill Stoddard]
2658 *) Provide $0..$9 results from mod_include regex parsing.
2661 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
2663 *) Introduced the ForceLanguagePriority directive, to prevent
2664 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
2665 when using Multiviews. [William Rowe]
2667 *) Fix a problem which prevented mod_cgid and suexec from working
2668 together reliably [Greg Ames]
2670 *) Remove the call to exit() from within mod_auth_digest's post_config
2671 phase. [Aaron Bannert]
2673 *) Fix a problem in mod_auth_digest that could potentially cause
2674 problems with initialized static data on a system that uses DSOs.
2677 *) Fix a segfault in the worker MPM that could happen during
2678 child process exits. [Brian Pane, Aaron Bannert]
2680 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
2682 *) Fix matching of vhosts by ip address so we find IPv4
2683 vhost address when target address is v4-mapped form of
2684 that address. [Jeff Trawick]
2686 *) More performance tweaks to the BNDM string-search algorithm
2687 used to find "<!--#" tokens in mod_include [Brian Pane]
2689 *) Miscellaneous small performance fixes: optimized away various
2690 string copy operations and removed large temp buffers from
2691 the stack [Brian Pane]
2693 *) Fixed startup segfault that occurred when a VirtualHost
2694 directive had a port but no address [Brian Pane]
2696 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
2698 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
2699 if oslevel < WINNT. This should fix several problems reported
2700 Against 2.0.28 on Windows 98 [Bill Stoddard]
2702 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
2703 to fail. [Bill Stoddard]
2705 *) Change core code to allow an MPM to set hard thread/server
2706 limits at startup. prefork, worker, and perchild MPMs now have
2707 directives to set these limits. [Jeff Trawick]
2709 *) Win32: The async AcceptEx() event should be autoreset upon
2710 successful completion of a wait (WaitForSingleObject). This
2711 eliminates a number of spurious
2712 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
2715 *) Move any load library path environment variables out of
2716 apachectl and into a separate environment variable file which
2717 can be more easily tailored by the admin. The environment
2718 variable file as built by Apache may have additional system-
2719 specific settings. For example, on OS/390 we tailor the heap
2720 settings to allow lots of threads. [Jeff Trawick]
2722 *) Use the new APR pool code to reduce pool-related lock
2723 contention in the worker MPM. [Sander Striker]
2725 *) The POD no longer assumes the child is listening on 127.0.0.1
2726 and now pulls the first hostname in the list of listeners to
2727 perform the dummy connect on. This fixes a bug when the user
2728 had configured the Listen directive for an IP other than
2729 127.0.0.1. This would result in undead children and error
2730 messages such as "Connection refused: connect to listener".
2733 *) The worker MPM now respects the LockFile setting, needed to
2734 avoid locking problems with NFS. [Jeff Trawick]
2736 *) Fix segfault when worker MPM receives SIGHUP.
2737 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
2739 *) Fix bug that could potentially prevent the perchild MPM from
2740 working with more than one vhost/uid. [Aaron Bannert]
2742 *) Change make install and apxs -i processing of DSO modules to
2743 perform special handling on platforms where libtool doesn't install
2744 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
2745 which prevented standard LoadModule statements from working.
2748 *) Whenever mod_so is enabled (not just when there are DSOs for
2749 our modules), do whatever special magic is required for compiling/
2750 loading third-party modules. This allows third-party DSOs to
2751 be used on an AIX build when there were no built-in modules
2752 built as DSOs. (This should help on OS/390 and BeOS as well.)
2755 *) Allow apxs to be used to build DSOs on AIX without requiring the
2756 user to hard-code the list of import files. (This should help
2757 on OS/390 and BeOS as well.) [Jeff Trawick]
2759 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
2760 PR 8563, 8919 [William Rowe]
2762 *) Get binary builds working when libapr and libaprutil are built
2765 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
2766 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
2767 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
2769 *) Fix the handling of SSI directives in which the ">" of the
2770 terminating "-->" is the last byte in a file [Brian Pane]
2772 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
2773 message that we had back in apache-1.3 and still have scattered
2774 throughout our docs. [Aaron Bannert]
2776 *) Prevent the Win32 port from continuing after encountering an
2777 error in the command line args to apache. [William Rowe]
2779 *) On a error in the proxy, make it write a line to the error log
2782 *) Various mod_ssl performance improvements [Doug MacEachern]
2784 Changes with Apache 2.0.29
2786 *) Add buffering in core_output_filter to ensure that long
2787 lists of small buckets don't cause small packet writes.
2788 [Brian Pane, Ryan Bloom]
2790 *) Fix the installation target to make sure that the manual is
2791 installed in the correct location.
2792 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
2793 Gomez Henri <hgomez slib.fr>]
2795 *) Fix the cmd command for mod_include. When we are processing
2796 a cmd command, we do not want to use the r->filename to set
2797 the command name. The command comes from the SSI tag. To do this,
2798 I added a variable to the function that builds the command line
2799 in mod_cgi. This allows the include_cmd function to specify
2800 the command line itself. [Ryan Bloom]
2802 *) Change open_logs hook to return a value, allowing you
2803 to flag a error while opening logs
2804 [Ian Holsman, Doug MacEachern]
2806 *) Change post_config hook to return a value, allowing you
2807 to flag a error post config
2808 [Ian Holsman, Jeff Trawick]
2810 *) Allow SUEXEC_BIN (the path to the suexec binary that is
2811 hard-coded into the server) to be specified to the configure
2812 script by the --with-suexec-bin parameter. [Aaron Bannert]
2814 *) Fix segv in worker MPM following accept on pipe-of-death
2817 *) Add mod_deflate to experimental.
2818 [Ian Holsman, Justin Erenkrantz]
2820 *) Bail out at configure time if an invalid MPM was specified.

2836 *) The threaded MPM for Unix has been removed. Use the worker
2837 MPM instead. [various]
2839 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
2840 in logging the error from a failed DNS lookup. [Jeff Trawick]
2842 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
2845 *) Get mod_cgid killed when a MPM exits due to a fatal error.
2848 *) Fix a file descriptor leak in mod_include. When we include a
2849 file, we use a sub-request, but we didn't destroy the sub-request
2850 immediately, instead we waited until the original request was
2851 done. This patch closes the sub-request as soon as the data is
2852 done being generated. [Brian Pane <bpane pacbell.net>]
2854 *) Allow modules that add sockets to the ap_listeners list to
2855 define the function that should be used to accept on that
2856 socket. Each MPM can define their own function to use for
2857 the accept function with the MPM_ACCEPT_FUNC macro. This
2858 also abstracts out all of the Unix accept error handling
2859 logic, which has become out of synch across Unix MPMs.
2862 *) Fix a bug which would cause the response headers to be omitted
2863 when sending a negotiated ErrorDocument because the required
2864 filters were attached to the wrong request_rec.
2865 [John Sterling <sterling covalent.net>]
2867 *) Remove commas from the end of the macros that define
2868 directives that are used by MPMs. Prior to this patch,
2869 you would use these macros without commas, which was unlike
2870 the macros for any other directives. Now, the caller provides
2871 the comma rather than the macro providing it. This makes
2872 the macros look more like the rest of the directives.
2873 [Ryan Bloom and Cliff Woolley]
2875 *) Add 'redirect-carefully' environment option to disable sending
2876 redirects under special circumstances. This is helpful for
2877 Microsoft's WebFolders when accessing a directory resource via
2878 DAV methods. [Justin Erenkrantz]
2880 *) Begin to abstract out the underlying transport layer.
2881 The first step is to remove the socket from the conn_rec,
2882 the server now lives in a context that is passed to the
2883 core's input and output filters. This forces us to be very
2884 careful when adding calls that use the socket directly,
2885 because the socket isn't available in most locations.
2888 *) Really reset the MaxClients value in worker and threaded
2889 when the configured value is not a multiple of the number
2890 of threads per child. We said we did previously but we
2891 forgot to. [Jeff Trawick]
2893 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
2895 *) If shared modules are requested and mod_so is not available,
2896 produce a fatal config-time error. [Justin Erenkrantz]
2898 *) Improve http2env's performance by cutting the work it has to
2899 do. [Brian Pane <bpane pacbell.net>]
2901 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
2902 [Brian Pane <bpane pacbell.net>]
2904 Changes with Apache 2.0.28
2906 *) Fix infinite loop in mod_cgid.c.
2907 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
2909 *) When no port is given in a "ServerName host" directive, the
2910 server_rec->port is now set to zero, not 80. That allows for
2911 run-time deduction of the correct server port (depending on
2912 SSL/plain, and depending also on the current setting of
2913 UseCanonicalName). This change makes redirections
2914 work, even with https:// connections. As in Apache-1.3, the
2915 connection's actual port number is never used, only the ServerName
2916 setting or the client's Host: setting. Documentation updated
2917 to reflect the change. [Martin Kraemer]
2919 *) Add a '%{note-name}e' argument to mod-headers, which works in
2920 the same way as mod_log_confg. [Ian Holsman]
2922 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
2923 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
2924 MPMs. [Cliff Woolley]
2926 *) Introduce htdbm, a user management utility for db/dbm authorization
2927 databases. [Mladen Turk <mturk mappingsoft.com>]
2929 *) Optimize usage of strlen and strcat in ap_directory_walk.
2930 [Brian Pane <bpane pacbell.net>]
2932 Changes with Apache 2.0.27
2934 *) Introduce an Apache mod_ssl initial configuration template
2935 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
2937 *) Fixed a memory leak in the getline parsing code that could
2938 be triggered by arbitrarily large header lines. Requests
2939 from the core input filter for single lines are now limited
2940 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
2942 *) Fix a truncation bug in how we print the port on the Via: header.
2943 The routine that prints the Via: header now takes a length for
2944 the port string. [Zvi Har'El <rl math.technion.ac.il>]
2946 *) Some syntax errors in mod_mime_magic's magic file can result
2947 in a 500 error, which previously was unlogged. Now we log the
2948 error. [Jeff Trawick]
2950 *) Add the support/checkgid helper app, which checks the run-time
2951 validity of group identifiers usable in the Group directive.
2954 *) Various --enable-so options have been fixed: --enable-so is
2955 treated as "static"; explicit --enable-so=shared issues an error;
2956 and explicit --enable-so fails with error on systems without
2957 APR_HAS_DSO. [Aaron Bannert]
2959 *) Fix a segfault in the core input filter when the client socket
2960 gets disconnected unexpectedly. [Cliff Woolley]
2962 *) Fix the reporting for child processes that die. This removes
2963 all of the non-portable W* macros from Apache.
2964 [Jeff Trawick and Ryan Bloom]
2966 *) Win32: Track and display "Parent Server Generation:" in
2967 mod_status output. The generation will be bumped at
2968 server graceful restart, when the child process exits
2969 by hitting MaxRequestsPerChild or if the child
2970 process exits abnormally. [Bill Stoddard]
2972 *) Win32: Fix problem where MaxRequestsPerChild directive was
2973 not being picked up in favor of the default. Enable
2974 the parent to start up a new child process immediately upon
2975 the old child starting shutdown.
2978 *) Fix some bungling of the remote port in rfc1413.c so that
2979 IdentityCheck retrieves the proper user id instead of failing
2980 and thus always returning "nobody."
2981 [Dick Streefland <Dick.Streefland xs4all.nl>]
2983 *) Introduced thread saftey for mod_rewrite's internal cache.
2984 [Brian Pane <bpane pacbell.net>]
2986 *) Simplified mod_env's directives to behave as most directives are
2987 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
2988 directive following that UnsetEnv within the same container.
2989 Also provides a runtime startup warning if a PassEnv configured
2990 environment value is undefined. [William Rowe]
2992 *) The worker MPM is now completely ported to APR's new lock API. It
2993 uses native APR types for thread mutexes, cross-process mutexes,
2994 and condition variables. [Aaron Bannert]
2996 *) Sync up documentation to remove all references to the now deprecated
2997 Port directive. [Justin Erenkrantz]
2999 *) Moved all ldap modules from the core to httpd-ldap sub-project
3002 *) Exit when we can't listen on any of the configured ports. This
3003 is the same behavior as 1.3, and it avoids having the MPMs to
3004 deal with bogus ap_listen_rec structures. [Jeff Trawick]
3006 *) Cleanup the proxy code that creates a request to the origin
3007 server. This change adds an optional hook, which allows modules
3008 to gain control while the request is created if the proxy module
3009 is loaded. The purpose of this hook is to allow modules to add
3010 input and/or output filters to the request to the origin. While
3011 I was at it, I made the core use this hook, so that proxy request
3012 creation uses some of the code from the core. This can still be
3013 greatly improved, but this is a good start. [Ryan Bloom]
3015 Changes with Apache 2.0.26
3017 *) Port the MaxClients changes from the worker MPM to the threaded
3020 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
3021 with the new input filtering system. [Justin Erenkrantz]
3023 *) Introduce the MultiviewsMatch directive, to allow the operator
3024 to be flexible in recognizing Handlers and Filters filename
3025 extensions as part of the Multiviews matching logic, strict with
3026 MultiviewsMatch NegotiatedOnly to accept only filename extentions
3027 that designate negotiated parameters, (content type, charset, etc.)
3028 or MultiviewsAll for the 1.3 behavior of matching any files, even
3029 if they have unregistered extensions. [William Rowe]
3031 *) Fixed the configure script to add a LoadModule directive to
3032 the default httpd.conf for any module that was compiled
3033 as a DSO. [Aaron Bannert <aaron clove.org>]
3035 *) rewrite mod_ssl input filtering to work with the new input filtering
3036 system. [Justin Erenkrantz]
3038 *) prefork: Don't segfault when we are able to listen on some but
3039 not all of the configured ports. [Jeff Trawick]
3041 *) Build mod_so even if no core modules are built shared.
3042 [Aaron Bannert <aaron clove.org>]
3044 *) Introduce ap_directory_walk rewrite (with further optimizations
3045 required) to adapt to the ap_process_request_internal() changes.
3046 Optimized so subrequests and redirects now reuse previous section
3047 merges, until we mismatch with the original directory_walk, and
3048 precomputed r->finfo results will cause directory_walk to skip
3049 the most expensive phases of the function. [William Rowe]
3051 *) Allow ApacheMonitor to connect to and control Apache on other
3052 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
3054 *) Remove the Port directive. In it's place, the Listen directive
3055 is now a required directive, which tells Apache what port to
3056 listen on. The ServerName directive has also been extended
3057 to accept an optional port. If the port is specified to the
3058 ServerName, the server will report that port whenever it
3059 reports the port that it is listening on. This change was
3060 made to ease configuration errors that stem from having a Port
3061 directive, and a Listen directive. In that situation, the server
3062 would only listen to the port specified by the Listen command,
3063 which caused a lot of confusion to users. [Ryan Bloom]
3065 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
3066 build, as loadable modules. [William Rowe]
3068 *) Fix --enable-mods-shared processing. If most is specified,
3069 then all modules that can be compiled as shared modules are.
3070 [Aaron Bannert <aaron clove.org>]
3072 *) Update the mime.types file to map video/vnd.mpegurl to mxu
3073 and add commonly used audio/x-mpegurl for m3u extensions.
3074 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
3076 *) Eliminate the depreciated r->content_language, in favor of the array
3077 r->content_languages introduced many years ago. Module authors must
3078 substantially overhaul their modules, so this needs to be upgraded
3079 if the module still relied on backwards-brokeness. [William Rowe]
3081 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
3084 *) Rewrite the input filtering mechanisms to consolidate and reorganize
3085 code. In short, core_input_filter does something now and
3086 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
3088 *) Update the Win32 build to re-absorb mod_proxy and family.
3091 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
3092 current SDK.) [William Rowe]
3094 *) Some style changes to the code that does ProxyErrorOverride. Fixed
3095 config merge behaviour. [Graham Leggett]
3097 *) Allow support programs to be compiled against a static version
3098 of libapr. This allows the smaller support programs to be
3099 relocated. [Aaron Bannert <aaron clove.org>]
3101 *) Update the mime.types file to the registered media types as
3102 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
3104 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
3105 number of clients that can connect at the same time, instead of
3106 specifying the maximum number of child processes.
3107 [Aaron Bannert <aaron clove.org>]
3109 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
3110 be consistent with 1.3. [Justin Erenkrantz]
3112 *) Cache apr_explode_localtime() value for 15 seconds.
3113 [Brian Pane <bpane pacbell.net>]
3115 *) Fix mod_include to not return ETag or Last-Modified headers.
3116 [Ian Holsman <ianh cnet.com>]
3118 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
3120 *) Eliminate the wasteful run-time conversion of method names from strings
3121 to numbers in places where the methods are known at compile time.
3122 [Brian Pane <bpane pacbell.net>]
3124 *) Turn the worker MPM's queue into a LIFO. This may
3125 improve cache-hit performance under some conditions.
3126 [Aaron Bannert <aaron clove.org>]
3128 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
3129 support it. [Justin Erenkrantz]
3131 *) Cleanup the worker MPM. We no longer re-use transaction
3132 pools. This incurs less overhead than shuffling the pools
3133 around so that they can be re-used. Remove one of the
3134 queue's condition variables. We just redefined the API to
3135 state that you can't try to add more stuff than you allocated
3136 segments for. [Aaron Bannert <aaron clove.org>]
3138 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
3140 *) Fixed persistent connections when a request contains a body.
3143 *) mod_dav uses a new API to speak to the backend provider for dead
3144 property management. [Greg Stein]
3146 *) Remove the Win32 script-processing exception from mod_cgi, and
3147 roll build_command_line/build_argv_list into a unified, overrideable
3148 ap_cgi_build_command optional function. [William Rowe]
3150 *) Rewrite find_start_sequence to use a better search algorithm
3151 to find the start tag. [Justin Erenkrantz]
3153 *) Fix a seg fault in mod_include. When we are generating an
3154 internal redirect, we must set r->uri to "", not a bogus
3155 string, and not NULL. [Ryan Bloom]
3157 *) Optimized location_walk, so subrequests, redirects and second passes
3158 now reuse previous section merges on a <Location > by <Location >
3159 basis, until we mismatch with the original location_walk.
3162 *) Back out the 1.45 change to util_script.c. This change made
3163 us set the environment variable REQUEST_URI to the redirected
3164 URI, instead of the originally requested URI.
3165 [Taketo Kabe <kabe sra-tohoku.co.jp>]
3167 *) Make mod_include do lazy evaluation of potentially expensive to
3168 compute variables. [Brian Pane <bpane pacbell.net>]
3170 *) Fix logging of bytes sent for HEAD requests. %b and %B should
3171 log either - or 0, before this patch, they were both logging
3172 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
3174 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
3175 than per character. [Brian Pane <bpane pacbell.net>]
3177 *) Normalize the primary request, redirects and sub-requests to
3178 run the same ap_process_request_internal for consistency in
3179 robustness, behavior and security. [William Rowe]
3181 *) Fix a segfault with mod_include when r->path_info is not set
3182 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
3184 *) Add -X functionality back. This indicates to all MPMs and any other
3185 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
3187 *) Some initial support for the cygwin platform [prefork only].
3188 This is not to be confused with support for the WinNT/Win32
3189 platform, which is the recommended configuration for native
3190 Win32 users. The cygwin platform support is recommended for
3191 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
3193 *) Changed syntax of Set{Input|Output}Filter. The list of filters
3194 must be semicolon delimited (if more than one filter is given.)
3195 The Set{Input|Output}Filter directive now overrides a parent
3196 container's directive (e.g. SetInputFilter in <Directory /web/foo>
3197 will override any SetInputFilter directive in <Directory /web>.)
3198 This new syntax is more consistent with Add{Input|Output}Filter
3199 directives defined in mod_mime. Also cures a bug in prior releases
3200 where the Set{Input|Output}Filter directive would corrupt the
3201 global configuration if the multiple directives were nested.
3204 *) Cured what's ailed mime for quite some time. If an AddSomething
3205 was given in the configuration (Language, Charset, Handler or
3206 Encoding) Apache would set the content type as given by AddType,
3207 but refused to check the mime.types file if AddType wasn't given
3208 for that specific extension. Setting the AddHandler for .html
3209 without setting the AddType text/html html would cause Apache to
3210 use the default content type. [William Rowe]
3212 *) Added some bulletproofing to memory allocation in the LDAP cache
3213 code. [Graham Leggett]
3215 Changes with Apache 2.0.25
3217 *) Move the installed /manual directory out of the /htdocs/ tree, so
3218 that it can be kept more independently from the remaining document
3219 root. The "Alias /manual ..." already allowed for easy projection
3220 into existing private document trees. [Martin Kraemer]
3222 *) Add specified user attributes to the environment when using
3223 mod_auth_ldap. This allows you to use mod_include to embed specified
3224 user attributes in a page like so:
3225 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
3228 *) Fix a performance problem with the worker MPM. We now create
3229 transaction pools once, and re-use them for each connection.
3230 [Aaron Bannert <aaron clove.org>]
3232 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
3233 of a 'handler' or 'filter', so that any filename extension that does
3234 not contribute to the negotiated metadata can't be served without
3235 an explicit request. E.g., if the .Z extension is associated with
3236 an unzip filter, the user request somefile.Z.html, mod_negotiation
3237 won't serve it. It can serve somefile.Z.html when somefile.Z is
3238 requested, since the .Z extension is explictly requested, if the
3239 .html extension is associated with ContentType text/html.
3242 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
3243 and corresponding AddOutputFilter syntax, to insert one or more
3244 filters by mod_mime filename extension processing.
3247 *) Fix a growing connection pool in core_output_filter() for
3248 keepalive requests. [Jeff Trawick]
3250 *) Moved split_and_pass_pretag_buckets back to being a
3251 macro at Ryans's request. Removed the return from it
3252 by setting and returning a return code instead. Updated
3253 the code to check the return code from the macro and
3254 do the right thing. [Paul J. Reder]
3256 *) Fix a segfault when a numeric value was received for Host:.
3259 *) Add a function ap_remove_input_filter. This is to match
3260 up with ap_remove_output_filter. [Ryan Bloom]
3262 *) Clean up location_walk, so that this step performs a minimum
3263 amount of redundant effort (it must be run twice, but it will no
3264 longer reparse all <Location > blocks when the request uri
3265 hadn't changed.) [William Rowe]
3267 *) Eliminate proxy: (and all other 'special') processing from the
3268 ap_directory_walk() phase. Modules that want to use special
3269 walk logic should refer to the mod_proxy map_to_location example,
3270 with it's proxy_walk and proxysection implementation. This makes
3271 either directory_walk flavor much more legible, since that phase
3272 only runs against real <Directory > blocks.
3275 *) SECURITY: Fix a security problem in mod_include which would allow
3276 an SSI document to be passed to the client unparsed.
3277 [Cliff Woolley, Brian Pane]
3279 *) Introduce the map_to_storage hook, which allows modules to bypass
3280 the directory_walk and file_walk for non-file requests. TRACE
3281 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
3282 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
3285 *) Add the ability for mod_include to add the INCLUDES filter
3286 if the file is configured for the server-parsed handler.
3287 This makes the configuration for .shtml files much easier
3288 to understand, and allows mod_include to honor Apache 1.3
3289 config files. Based on Doug MacEachern's patch to PHP
3290 to do the same thing. [Ryan Bloom]
3292 *) force OpenSSL to ignore process local-caching and to always
3293 get/set/delete sessions using mod_ssl's callbacks
3294 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3295 Geoff Thorpe <geoff geoffthorpe.net>]
3297 *) Make the worker MPM shutdown and restart cleanly. This also
3298 cleans up some race conditions, and gets the worker using
3299 pools more cleanly. [Aaron Bannert <aaron clove.org>]
3301 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
3303 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3305 *) Fix for mod_include. Ryan's patch to check error
3306 codes put a return in the wrong place. Also, the
3307 include handler return code wasn't being checked.
3308 I don't like macros with returns, so I converted
3309 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
3310 [Paul J. Reder <rederpj raleigh.ibm.com>]
3312 *) fix segv in mod_mime if no AddTypes are configured
3313 [John Sterling <sterling covalent.net>]
3315 *) Enable ssl client authentication at SSL_accept time
3316 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3318 *) Fix a segfault in mod_include when the original request has no
3319 associated filename (e.g., we're filtering the error document for
3320 a bad URI). [Jeff Trawick]
3322 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
3324 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
3325 of httpd is started and shuts down due to socket conflict. Moving the
3326 call to ap_log_pid solves the problem.
3328 *) Changed the late-1.3 log_config substitution %c to %X, to log the
3329 status of the closed connection, as it conflicts with the far more
3330 common, historical ssl logging directive %...{var}c. [William Rowe]
3332 *) Added the common error/ tree to the build/install targets
3333 (similar to the common icons/ tree) for the multi-language error
3334 messages that Lars committed earlier. [William Rowe]
3336 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
3338 *) Added a default commented-out mod_ldap and mod_auth_ldap
3339 configuration to httpd-std.conf and httpd-win.conf
3342 *) Added documentation for mod_ldap and mod_auth_ldap.
3345 *) Enabled negative caching on attribute comparisons in the LDAP cache.
3346 Fixed a problem where the default cache TTL was set in milliseconds
3347 not microseconds causing the cache to time out almost immediately.
3350 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
3351 module code to follow APR. [Graham Leggett]
3353 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
3354 cleaned up when the connection pool pool is cleaned up.
3357 *) Fix a minor issue with Jeff Trawick's mod_include
3358 patch. Without this patch, the code will just allocate
3359 more bytes in get_combined_directive than are needed.
3362 *) Added the LDAP authentication module mod_auth_ldap.
3363 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3365 *) Added the LDAP cache and connection pooling module mod_ldap.
3366 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3368 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
3369 by allowing a module to disable itself if its prerequisites are not
3370 met. [Justin Erenkrantz]
3372 Changes with Apache 2.0.24
3374 *) Fix a couple of issues in mod_include when the tag appeared at
3375 offsets near 8192 in the file being parsed. [Jeff Trawick]
3377 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
3378 reached. [Jeff Trawick]
3380 *) Numerous improvements to the Win32 build system. Introduced command line
3381 builds without requiring .mak files for MSVC 6.0 and later versions.
3382 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
3385 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
3386 reporting of uninstalled services and other error conditions, and changed the
3387 default service name to Apache2. [William Rowe]
3389 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
3390 compatibility with existing Apache 1.3 Win32 Apache management utilites.
3391 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
3393 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
3394 [William Rowe, Greg Ames]
3396 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
3397 and RemoveCharset directives. [William Rowe]
3399 *) The Unix MPMs other than perchild now allow child server
3400 processes to use the accept mutex when starting as root and
3401 using SysV sems for the accept mutex. Previously, this
3402 combination would lead to fatal errors in the child server
3403 processes. perchild can't use SysV sems because of security
3404 issues. [Jeff Trawick, Greg Ames]
3406 *) Added Win32 revision stamp resources to all http binaries
3407 (including modules/ and support/ tools.) PR7322 [William Rowe]
3409 *) Fix ap_rvprintf to support more than 4K of data at one time.
3410 [Cody Sherr <csherr covalent.net>]
3412 *) We have always used the obsolete/deprecated Netscape syntax
3413 for our tracking cookies; now the CookieStyle directive
3414 allows the Webmaster to choose the Netscape, RFC2109, or
3415 RFC2965 format. The new CookieDomain directive allows the
3416 setting of the cookie's Domain= attribute, too. PR #s 5006,
3417 5023, 5920, 6140 [Ken Coar]
3419 *) Tweak server/Makefile so that the rules for generating exports.c
3420 are compatible with make utilities which don't expand wildcards
3421 in a dependency list (e.g., OS/390 make, certain levels of GNU
3422 make). [Jeff Trawick]
3424 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
3426 *) Begin to sanitize the MPM configuration directives. Now, all
3427 MPMs use the same functions for all common MPM directives. This
3428 should make it easier to catch all bugs in these directives once.
3429 [Cody Sherr <csherr covalent.net>]
3431 *) Close a major resource leak. Every time we had issued a
3432 graceful restart, we leaked a socket descriptor.
3435 *) Fix a problem with the new method code. We need to cast
3436 the 1 to an apr_int64_t or it will be treated as a 32-bit
3437 integer, and it will wrap after being shifted 32 times.
3438 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
3440 *) Fix a bug in mod_expires. Previous to this patch, if you
3441 told mod_expires to add 604800 seconds to the last-modified
3442 time, it actually added 604800 usec's to the last-modified time,
3443 so that when looking at the response it looked like nothing
3444 had been done. The root of the problem was that we always compute
3445 time in usec's, but we ask users to input sec's. This means we
3446 need to convert to usec's before using those values.
3449 *) The worker MPM now handles shutdown and restart requests. It
3450 definitely isn't perfect, but we do stop the servers correctly.
3451 The biggest problem right now is that SIGHUP causes the server to
3452 just die. [Ryan Bloom]
3454 Changes with Apache 2.0.23
3456 *) Use the prefork MPM by default on Unix. [various]
3458 *) Added a systray icon monitor application for Win32.
3459 [Mladen Turk <mturk mappingsoft.com>]
3461 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3462 messages written to the rewrite log.
3463 [Richard Labennett <rlabenn us.ibm.com>]
3465 *) All mod_autoindex query parsing is now quietly quashed with the
3466 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3467 still drops the column sort <a href>'s for the column headers, but
3468 IgnoreClient is required to ignore these Query options entirely.
3471 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3472 to allow the client to select plain, FancyIndexing or HTMLTable
3473 formatting, V=[0|1] to inhibit or enable version sorting, and
3474 P=pattern to return only specific files. The old Query Arguments
3475 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3476 as before), and O=A|D for ordering ascending or descending.
3479 *) Fixed an error in mod_include's directive parsing routines which
3480 caused #if, #elif, and #else expressions containing backslashes
3481 to be improperly evaluated. [Cliff Woolley]
3483 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3484 drop the icon column, SuppressRules to drop the <hr> elements,
3485 and HTMLTable to create rudimentary HTML table listings (implies
3486 FancyIndexing). [William Rowe]
3488 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3489 from Apache 1.3.15. This is needed for two reasons, first, given
3490 multiple machines within a server farm, ETags and Last-Modified
3491 stamps won't correspond from machine to machine, and second, many
3492 Unixes don't capture changes to the date or time stamp of existing
3493 files, since these don't modify the dirent itself. [William Rowe]
3495 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3496 and DirectoryWidth options from Apache 1.3.10.
3497 [William Rowe, Ken Coar]
3499 *) Eliminated FancyIndexing directive, deprecated early in Apache
3500 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3502 *) mod_autoindex now excludes any file names that would result in
3503 an error, other than a success or redirect. Also optimized
3504 the parent directory, always included except in the URI '/'.
3507 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3508 negotiated index pages, and prevent the server from defaulting
3509 to an autoindex of the directory. mod_negotiation will now die
3510 with a 500 Internal Error if it could match some filenames
3511 (e.g. for mod_dir) but none can be served. mod_negotation now
3512 refuses to serve any file with an extention that mod_mime doesn't
3513 recognize, and wasn't part of the request. [William Rowe]
3515 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3516 extension. This is already handled by multiviews, if the admin
3517 wishes to AddHandler .exe or define a content type handler and
3518 associate .exe files with that content type. Multiviews must be
3519 enabled to allow these to be served. [William Rowe]
3521 *) Speed up the server's response to a spike in incoming workload
3522 or restarts by assigning empty scoreboard slots to new processes
3523 when they are available. [Greg Ames]
3525 *) Add a handler to mod_includes.c. This handler is designed to
3526 implement the XbitHack directive. This can't be done with a
3527 fixup, because we need to check the content-type, which is
3528 only available in the handler phase. [Ryan Bloom]
3530 *) Make the includes filter check return codes from filters lower in
3531 the filter chain. If a lower level filter returns an error, then
3532 the request needs to stop immediately. This allows mod_include to
3533 stop parsing data once a lower filter recognizes an error.
3536 *) Add the ability to extend the methods that Apache understands
3537 and have those methods <limit>able in the httpd.conf. It uses
3538 the same bit mask/shifted offset as the original HTTP methods
3539 such as M_GET or M_POST, but expands the total bits from an int to
3540 an ap_int64_t to handle more bits for new request methods than
3541 an int provides. [Cody Sherr <csherr covalent.net>]
3543 *) Fix broken mod_mime behavior in merging its arguments. Possible
3544 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
3546 *) Solve many mod_ssl porting issues (too many to detail) with
3547 help from the whole team, but most notably [Ralf S. Engelschall,
3548 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3549 Doug MacEachern, William Rowe, Cliff Woolley]
3551 *) More stall fixes for the threaded & worker mpm's.
3552 Make mod_status output more accurate. Don't
3553 count workers in processes which aren't actively
3554 serving requests. [Greg Ames]
3556 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
3558 *) Add a single listener/multiple worker MPM. This MPM is
3559 definately not fully correct, but it allows us to solve many
3560 of the problems that exist in the threaded MPM. This is a
3561 modified version of the threaded MPM. [Ryan Bloom]
3563 *) Improve content generation throughout Apache, providing closer
3564 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
3565 Transitional specifications. [William Rowe]
3567 Changes with Apache 2.0.22
3569 *) Fix a problem where the threaded MPM stalls after restarts or
3570 segfaults. Also prevent multiple active processes from using
3571 the same scoreboard slot. [Greg Ames]
3573 *) Apache/Win32 now fills in the service description with Apache's
3574 server version string, including loaded and advertised modules.
3577 *) Improved support for the Win32 build, to recover gracefully from
3578 missing apr or apr-util directories or the awk interpreter,
3579 create the proper cgi-bin examples, including a test-cgi.bat, and
3580 fix the perl shebang line for printenv.pl, when installing from
3581 the build environment. [William Rowe]
3583 *) Fix a segfault in threaded.c caused by passing uninitialized
3584 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
3586 *) Use new APR number conversion functions to reduce CPU consumption
3587 when setting the content length, and in mod_log_config.
3590 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
3591 where HEAD response headers were being repeated twice for
3592 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
3593 problem in the http_header filter was exposed by the recent rewrite
3594 of the content_length filter. [Taketo Kabe, Bill Stoddard]
3596 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
3597 restarts. A garbage pointer to a vhost's server_rec from the
3598 previous generation was being left around under certain
3599 conditions. [Greg Ames]
3601 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
3602 used to appear as '(none', without the closing paren.
3603 [Günter Knauf <eflash gmx.net>]
3605 *) Improve the exports generating awk script. In the past, we had
3606 work around problems in the awk script by avoiding some #if and
3607 #ifdefs. This has bitten us many times in generating the exports.c
3608 file. This improvement allows corrects the header file parsing.
3609 [Sander Striker <striker apache.org>]
3611 Changes with Apache 2.0.21
3613 *) Resolve the Win32 htpasswd bug, where a file that existed would be
3614 overwritten, regardless of the -c flag.
3615 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
3617 *) Introduce connection sub-pools into ab. Truncating the lifetime
3618 of these allocations means that ab no longer perpetually grows
3619 its working set, running out of memory on large request attempts.
3622 *) Make scoreboard creation a hook. This allows management
3623 modules to have access to the scoreboard at the time that it is
3624 created, and at every restart request.
3625 [Cody Sherr <csherr covalent.net>]
3627 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
3628 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
3629 daemon index actually used in the scoreboard. I also
3630 updated the pertinent calls. [Paul J. Reder]
3632 *) Win32: Prevent listening sockets from being inherited by
3633 the Apache child process, CGI scripts, rotatelog process
3634 etc. If the Apache child process segfaults, any processes
3635 that the child started are not reaped. Prior to this fix,
3636 these processes inherited the listening sockets which sometimes
3637 prevented the restarted Apache child process from accepting
3638 connections (ie, the server would hang).
3641 *) Provide vhost and request strings when ExtendedStatus is on.
3644 *) Fix some issues with the pod and prefork: check the pod *after*
3645 processing a connection so that a server processing a time-
3646 consuming request bails out as soon as practical; when the
3647 parent process wakes up a server process via connect(), use an
3648 APR timeout on the connect() so that we don't hang for a long
3649 time if there aren't server processes around to do accept().
3650 [Jeff Trawick, Greg Ames]
3652 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
3653 spends a lot of time in apr_table_get calls. Using the default
3654 httpd.conf, the tables for languages and charsets are somewhat
3655 large, so the time spent scanning them on each request is
3656 significant. Replacing the tables with hash tables provides
3657 a nice speedup. [Brian Pane <bpane pacbell.net>]
3659 *) Add two functions to allow modules to access random parts of the
3660 scoreboard. This allows modules compiled for one MPM to access the
3661 scoreboard, even if it the server was compiled for another MPM.
3662 [Harrie Hazewinkel <harrie covalent.net>]
3664 Changes with Apache 2.0.20
3666 *) Fix problem in content-length filter where the filter would
3667 buffer all the output from a CGI before sending any bytes
3668 down the filter stack to the network. This problem would cause
3669 significant memory consumption if the CGIs generated
3670 lots of bytes. [Bill Stoddard]
3672 *) Get non-blocking CGI pipe reads working with the bucket brigades.
3675 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
3678 *) Fix a bug in the threaded MPM that would cause it to kill off all
3679 workers immediately after starting if the number of workers started
3680 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
3682 Changes with Apache 2.0.19
3684 *) Fix problem with threaded MPM. The problem was that if each child
3685 process was busy serving a single long-lived request and the server
3686 was sent a graceful restart signal, the server would stop serving
3687 requests. This would happen because each child process would wait to
3688 die until the last thread was done, and the parent wouldn't spawn any
3689 new children until a process died. Now, the parent looks at the fact
3690 that the children are dying gracefully, and starts new children.
3691 Those new children only start enough threads to compliment the number
3692 of threads in the other child process that shares the same spot in
3693 the scoreboard. In this way, we make sure to never go over
3694 MaxClients. [Ryan Bloom]
3696 *) modified mod_negotiation and mod_autoindex to speed up by almost a
3697 factor of two on apr_dir_read()-enhanced platforms, such as Win32
3698 and OS2, by calling ap_sub_request_lookup_dirent() with the results
3699 already provided by apr_dir_read(). [William Rowe]
3701 *) mod_file_cache is now more robust to filtering and serves requests
3702 slightly more efficiently. [Cliff Woolley]
3704 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
3705 Module was calling ap_rwrite() followed by ap_rflush() but the
3706 served content was not being displayed in the browser. Inspection
3707 of the output stream revealed that the first data chunk was
3708 missing the trailing CRLF required by the RFC. [Bill Stoddard]
3710 *) apxs no longer generates ap_send_http_header() in the example handler
3712 *) Fix an ab problem which could cause a divide-by-zero exception
3713 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
3714 [Ian Holsman <ianh cnet.com>]
3716 *) Solve case-insensitive platforms' confusion about negotiated
3717 filenames, allowing files of differnt case to match in choosing
3718 the document to serve. [William Rowe]
3720 *) Fix brokenness when ThreadsPerChild is higher than the built-in
3721 limit. We left ap_threads_per_child at the higher value which
3722 led to segfaults when doing certain scoreboard operations.
3725 *) Fix seg faults and/or missing output from mod_include. The
3726 default_handler was using the subrequest pool for files and
3727 MMAPs, even though the associated APR structures typically
3728 live longer than the subrequest. [Greg Ames]
3730 *) Extend mod_setenvif to support specifying regular expressions
3731 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
3732 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
3733 will cause HAVE_TS to be set if any of the request headers begins
3734 with "TS" and has a value that begins with any character in the
3735 set [a-z]. [Bill Stoddard]
3737 *) httpd children now re-bind themselves to a random CPU on
3738 multiprocessor systems on AIX via bindprocessor() in 2.0.
3739 [Victor J. Orlikowski]
3741 *) Fix htdigest. It would go into a loop in getline when adding
3742 a second user. [Bill Stoddard]
3744 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
3746 *) Automatically generate httpd.exp for AIX.
3747 DSOs now work again on AIX in 2.0
3748 [Victor J. Orlikowski]
3750 *) Add a new request hook, error_log. This phase allows modules
3751 to act on the error log string _after_ it has been written
3752 to the error log. The goal for this hook is to allow monitoring
3753 modules to send the error string to the monitoring agent.
3756 *) Modify mod_echo to make it use filters for input and output.
3757 [Ryan Morgan <rmorgan covalent.net>]
3759 *) Extend mod_headers to support conditional driven Header
3760 add, append and set. Use SetEnvIf to set an envar and conditionally
3761 add/append/set headers based on this envar thusly:
3763 SetEnvIf TSMyHeader value HAVE_TSMyHeader
3764 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
3766 If the request contains header "TSMyHeader: value" then header
3767 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
3770 *) Extend mod_headers to support using format specifiers on Header
3771 add, append and set header values. Two format specifiers are supported:
3773 %t - reports, in UTC microseconds since the epoch, when the
3774 request was received.
3776 %D - reports the time, in microseconds, between when the request was
3777 received and the response sent.
3780 Header add MyHeader "This request served in %D microseconds. %t"
3782 results in a header being added to the response that looks like this:
3784 MyHeader: This request served in D=5438 microseconds. t=991424704447256
3788 *) Fix reset_filter(). We need to be careful how we remove filters.
3789 If we set r->output_filters to NULL, we also have to reset the
3790 connection's filters. [John Sterling]
3792 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
3794 *) Add a check to ap_die() to make sure the filter stack is sane and
3795 contains the correct basic filters when an error occurs. This fixes
3796 a problem where headers are not being sent on error. [John Sterling]
3798 *) New Header directive 'echo' option. "Header echo regex" will
3799 cause any headers received on the request that match regex to be
3800 echoed to (included in) the response headers.
3803 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
3804 This prevented the inclusion of apr_compat.h. PR #7773
3805 [Oleg Broytmann <phd phd.pp.ru>]
3807 *) Moved util_uri to the apr-util library. This required a bunch of
3808 apr_name changes for the uri utility functions. [Justin Erenkrantz]
3810 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
3811 insert_filter phase so that other filters are not bypassed by default.
3814 *) Reimplement mod_headers as an output filter. mod_headers can now
3815 add custom headers to inbound requests using the RequestHeader directive
3816 and to responses using the same old Header directive. [Graham Leggett]
3818 Changes with Apache 2.0.18
3820 *) Fix command-line processing so that if a bad argument is specified
3821 Apache will exit. [Jeff Trawick]
3823 *) Change the make targets and rules to be consistent in all of the
3824 Apache-owned source trees. [Roy Fielding]
3826 *) Fix processing of the TRACE method. Previously we passed bogus
3827 parms to form_header_field() and it overlaid some vhost structures,
3828 resulting in a segfault in check_hostalias().
3829 [Greg Ames, Jeff Trawick]
3831 *) Win32: Add support for reliable piped logs. If the logging process
3832 goes down, Apache will automatically restart it. This function has
3833 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
3836 *) Do not start piped log processes during the config file
3837 preflight. This change also circumvents a problem on
3838 Windows where the rotatelog processes created during preflight
3839 was not getting cleaned up properly.
3842 *) add "Request Phase Participation" info to mod_info
3845 *) Make first phase changes to the scoreboard data structures in
3846 preparation for the rewriting of the scoreboard per my posted
3847 design notes. [Paul J. Reder]
3849 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
3850 and apr-util, allow it to be overridden by the configure command-line
3851 (default="--silent") and introduce LT_LDFLAGS to replace what we were
3852 formerly abusing as LTFLAGS. [Roy Fielding]
3854 *) Clean up the reporting of incorrect closing container tags.
3855 [Barrie Slaymaker <barries slaysys.com>]
3857 *) Simplify the configure process by moving all libtool stuff to APR
3858 and moving hints.m4 inline. [Roy Fielding]
3860 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
3861 of functions used by mod_proxy for export in the DLL
3862 [Ian Holsman <IanH cnet.com>]
3864 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
3865 request body from its stdin but no reqest body is being written to
3866 the cgi. [Jeff Trawick]
3868 *) mod_log_config: %c connection status incorrectly logged
3869 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
3872 *) Get mod_cern_meta working under Windows
3875 *) Create Files, and thus MMAPs, out of the request pool, not the
3876 connection pool. This solves a small resource leak that had us
3877 not closing files until a connection was closed. In order to do
3878 this, at the end of the core_output_filter, we loop through the
3879 brigade and convert any data we have into a single HEAP bucket
3880 that we know will survive clearing the request_rec.
3881 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
3884 *) Completely revamp configure so that it preserves the standard make
3885 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
3886 the configure additions to EXTRA_* variables. Also, allow the user
3887 to specify NOTEST_* values for all of the above, which eliminates the
3888 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
3889 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
3890 avoid pointless duplications. Fix the order in which flags are given
3891 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
3892 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
3893 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
3894 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
3896 *) Get mod_tls to compile/work better on Windows. PR #7612
3897 [Bernhard Schrenk <b.schrenk improx.com>]
3899 *) Fix shutdown/restart hangs in the threaded MPM.
3900 [Jeff Trawick, Greg Ames, Ryan Bloom]
3902 *) Removed the keptalive boolean from conn_rec because it is now only
3903 used by a single routine and can be replaced by a local variable.
3904 [Greg Stein, Ryan Bloom, Roy Fielding]
3906 *) Patch prefork to put enough of the signal processing back in so that
3907 signals are all handled properly now. The previous patch fixed the
3908 deadlock race condition, but broke the user directed signal handling.
3909 This fixes it to work the way it did before my previous prefork patch
3910 (primarily, SIGTERM is now working).
3912 *) Change how input filters decide how much data is returned to the
3913 higher filter. We used to use a field in the conn_rec, with this
3914 change, we use an argument to ap_get_brigade to determine how much
3915 data is retrieved. [Ryan Bloom]
3917 *) Fix seg fault at start-up introduced by Ryan's change to enable
3918 modules to specify their own logging tags. mod_log_config
3919 registers an optional function, ap_register_log_handler().
3920 ap_register_log_handler() was being called by http_core before
3921 the directive hash table was created. This patch creates the
3922 directive hash table before ap_register_log_handler() is
3923 registered as an optional function.
3924 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
3926 *) Add ap_set_int_slot() function
3927 [John K. Sterling <sterling covalent.net>]
3929 *) Under certain circumstances, Apache did not supply the
3930 right response headers when requiring authentication.
3931 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
3932 (This is a port of the change that went into Apache 1.3.19.)
3934 *) Allow modules to specify their own logging tags. This basically
3935 allows a module to tell mod_log_config that when %x is encountered
3936 a specific function should be called. Currently, x can be any single
3937 character. It may be more useful to make this a string at some point.
3940 Changes with Apache 2.0.17
3942 *) If a higher-level filter handles the the byterange aspects of a
3943 request, then the byterange filter should not try to redo the
3944 work. The most common case of this happening, is a byterange
3945 request going through the proxy, and the origin server handles
3946 the byterange request. The proxy should ignore it.
3947 [Graham Leggett <minfrin sharp.fm>]
3949 *) Changed the threaded mpm to have child_main join to each of the
3950 worker threads to make sure the kids are all gone before child_main
3951 exits after a signal (cleanup from perform_idle_server_maintenance).
3952 This is an extension of Ryans recent commit to make the child_main
3955 *) Add more options to the ap_mpm_query function. This also allows MPMs to
3956 report if their threads are dynamic or static. Finally, this also
3957 implements a new API, ap_show_mpm, which returns the MPM that was
3958 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
3960 *) Do not install the binaries from the support directory twice.
3961 [jun-ichiro hagino <itojun iijlab.net>]
3963 *) The ap_f* functions should flush data to the filter that is passed
3964 in, not the the filter after the one passed in.
3965 [Ryan Morgan <rmorgan covalent.net>]
3967 *) Make ab work again by changing its native types to apr types and formats.
3968 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
3970 *) Move the byterange filter and all of the supporting functions back
3971 to the HTTP module. The byterange filter turned out to be very
3972 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
3974 *) Make clean, distclean, and extraclean consistently according to the
3975 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
3977 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
3978 This may have been causing problems stopping processes in the threaded
3981 *) Fix content-length in mod_negotiation to a long int representation.
3984 *) Remove BindAddress from the default config file.
3985 [<giles nemeton.com.au>]
3987 *) Allow module authors to add a module to their Apache build using
3988 --with-module, without re-running buildconf. The syntax is:
3989 --with-module=module_type:/path/to/module.c
3990 The configure script will copy the module.c file to
3991 modules/module_type, and it will be added to the relevant Makefiles.
3992 currently, this only works for static modules. [Ryan Bloom]
3994 *) Changes required to make prefork clean up idle children properly.
3995 There was a window during which a starting worker deadlocks when
3996 an idle cleanup arrives before it completes init. Apache then keeps
3997 trying to cleanup the same deadlocked worker forever (until higher
3998 pids come along, but it still will never reduce below the deadlocked
3999 pid). Thus the number of children would not reduce to the correct
4000 idle level. [Paul J. Reder]
4002 Changes with Apache 2.0.16
4004 *) Change the default installation directory to /usr/local/apache2,
4005 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
4007 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
4010 *) Get MaxRequestsPerChild working with the Windows MPM.
4013 *) Make generic hooks to work, with mod_generic_hook_import/export
4014 experimental modules. [Ben Laurie, Will Rowe]
4016 *) Fix segfaults for configuration file syntax errors such as
4017 "<Directory>" followed by "</Directory" and
4018 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
4020 *) Cleanup the --enable-layout option of configure. This makes
4021 us use a consistent location for the config.layout file, and it
4022 makes configure more portable.
4023 [jun-ichiro hagino <itojun iijlab.net>]
4025 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
4026 csv/gnuplot format, rudimentary ssl support and various other tweaks
4027 to make results more true to what is measured. The upshot of this it
4028 turns out that 'ab' has often underreported the true performance of
4029 apache. Often by a order of magnitude :-) See talk/paper of Sander
4030 Temme at April ApacheCon 2001 for details.
4031 [Dirk-Willem van Gulik]
4033 *) Clean up mod_cgid's temporary request pool. Besides fixing a
4034 storage leak this ensures that some unnecessary pipes are closed.
4037 *) Performance: Add quick_handler hook. This hook is called at the
4038 very beginning of the request processing before location_walk,
4039 translate_name, etc. This hook is useful for URI keyed content
4040 caches like Mike Abbott's Quick Shortcut Cache.
4043 *) top_module global variable renamed to ap_top_module [Perl]
4045 *) Move ap_set_last_modified to the core. This is a potentially
4046 controversial change, because this is kind of HTTP specific. However
4047 many protocols should be able to take advantage of this kind of
4048 information. I expect that headers will need one more layer of
4049 indirection for multi-protocol work, but this is a small step in
4050 the right direction. [Ryan Bloom]
4052 *) Enable mod_status by default. This matches what Apache 1.3 does.
4055 *) Add a ScriptSock directive to the default config file. This is
4056 only enabled when mod_cgid is used.
4057 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4059 Changes with Apache 2.0.15
4061 *) Untangled the buildconf script and eliminated the need for build's
4062 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
4063 libtool muck that is now under srclib/apr/build. [Roy Fielding]
4065 *) Win32: Don't accept more connections than we have worker threads
4069 *) Fix bug in the Unix threaded.c MPM that allowed child processes
4070 to fork() new child processes.
4073 *) SECURITY: Fix a major security problem with double-reverse lookup
4074 checking. Previously, a client connecting over IPv4 would not be
4075 matched properly when the server had an IPv6 listening socket.
4076 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
4078 *) Change the way the beos MPM handles polling to allow it to stop and
4079 restart. Problem was the sockets being polled were being reset by
4080 the select call, so once it had accepted a connection it was no
4081 longer listening on the UDP socket we use for shutdown instructions.
4082 APR needs to be altered, patch on it's way. [David Reid]
4084 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
4085 on error exit from ap_getline(). Some other code got upset because
4086 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
4088 *) Handle ap_discard_request_body() being called more than once.
4089 [Greg Ames, Jeff Trawick]
4091 *) Get rid of an inadvertent close of file descriptor 2 in
4092 mod_mime_magic. [Greg Ames, Jeff Trawick]
4094 *) Add a hook, create_request. This hook allows modules to modify
4095 a request while it is being created. This hook is called for all
4096 request_rec's, main request, sub request, and internal redirect.
4097 When this hook is called, the the r->main, r->prev, r->next
4098 pointers have been set, so modules can determine what kind of
4099 request this is. [Ryan Bloom]
4101 *) Cleanup the build process a bit more. The Apache configure
4102 script no longer creates its own helper scripts, it just
4104 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4106 *) Stop the forced downgrade of the connection to HTTP/1.0 for
4107 proxy requests. [Graham Leggett]
4109 *) Avoid using sscanf to determine the HTTP protocol number in
4110 the common case because sscanf is a performance hog. From
4111 Mike Abbot's Accelerating Apache patch number 6.
4112 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
4114 *) SECURITY: Fix a security exposure in mod_access. Previously when
4115 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
4116 were not evaluated properly (PR #7407). Also, add the ability to
4117 specify IPv6 address strings with optional prefix length on Allow
4118 and Deny. [Jeff Trawick]
4120 *) Enhance rotatelogs so that a UTC offset can be specified, and
4121 the logfile name can be formatted using strftime(3). (Brought
4122 forward from 1.3.) [Ken Coar]
4124 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
4125 DuplicateHandle on an IOCompletionPort (a practice which
4126 MS "discourages"). The new model does not rely on associating
4127 the completion port with the listening sockets, thus the
4128 completion port can be completely managed within the child
4129 process. A dedicated thread accepts connections off the network,
4130 then calls PostQueuedCompletionStatus() to wake up worker
4131 threads blocked on the completion port.
4134 *) Bring forward the --suexec-umask option which allows the
4135 builder to preset the umask for suexec processes. [Ken Coar]
4137 *) Add a -V flag to suexec, which causes it to display the
4138 compile-time settings with which it was built. (Only
4139 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
4141 *) Mod_include should always unset the content-length if the file is
4142 going to be passed through send_parsed_content. There is no to
4143 determine if the content will change before actually scanning the
4144 entire content. It is far safer to just remove the C-L as long
4145 as we are scanning it. [Ryan Bloom]
4147 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
4148 request and not Proxy-Authenticate.
4149 [Graham Leggett <minfrin sharp.fm>]
4151 Changes with Apache 2.0.14
4153 *) Fix content-length computation. We ONLY compute a content-length if
4154 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
4155 or we already have all the data. [Ryan Bloom]
4157 *) Report unbounded containers in the config file. Previously, a typo
4158 in the </container> directive could result in the rest of the config
4159 file being silently ignored, with undesired defaults used.
4162 *) Make the old_write filter use the ap_f* functions for the buffering.
4165 *) Move more code from the http module into the core server. This
4166 is core code, basically the default handler, the default input
4167 and output filters, and all of the core configuration directives.
4168 All of this code is required in order for the server to work, with or
4169 without HTTP. The server is closer to working without the HTTP
4170 module, although there is still more to do. [Ryan Bloom]
4172 *) Fix a number of SGI compile warnings throughout the server. Fix some
4173 bad parameters to apr_bucket_read(). Fix a bad statement in
4174 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
4175 consistently; we were mixing apr_time_t and time_t in invalid ways
4176 before. In load_file(), call apr_dso_error() instead of
4177 apr_strerror() so that we get a more specific string on some platforms.
4178 PR #6980 [Jeff Trawick]
4180 *) Allow modules to query the MPM about it's execution profile. This
4181 query API can and should be extended in the future, but for now,
4182 max_daemons, and threading or forking is a very good start.
4183 [Jon Travis <jtravis covalent.net>]
4185 *) Modify mod_include to send blocks of data no larger than 9k.
4186 Without this, mod_include will wait until the whole file is parsed,
4187 or the first tag is found to send any data to the client.
4188 [Paul J. Reder <rederpj raleigh.ibm.com>]
4190 *) Fix mod_info, so that <Directory> and <Location> directives are
4191 not displayed twice when displaying the current configuration.
4192 [Ryan Morgan <rmorgan covalent.net>]
4194 *) Add config directives to override DEFAULT_ERROR_MSG and
4195 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
4196 [Dan Rench <drench xnet.com>]
4198 *) Get mod_info building and loading on Win32. [William Rowe]
4200 *) Begin to move protocol independant functions out of mod_http. The goal
4201 is to have only functions that are HTTP specific in the http directory.
4204 Changes with Apache 2.0.13
4206 *) Don't assume that there will always be multiple calls to the byterange
4207 filter. It is possible that we will need to do byteranges with only
4208 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
4210 *) Move the error_bucket definition from the http module to the
4211 core server. Every protocol will need this ability, not just
4214 Changes with Apache 2.0.12
4216 *) Modify mod_file_cache to save pre-formatted strings for
4217 content-length and last-modified headers for performance.
4218 [Mike Abbot <mja trudge.engr.sgi.com>]
4220 *) Namespace protect IOBUFSIZ since it is exposed in the API.
4221 [Jon Travis <jtravis covalent.net>]
4223 *) Use "Basic" authentication instead of "basic" in ab, as the spec
4224 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
4226 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
4227 without ever filling it out. This fixes PR 7271.
4228 [Taketo Kabe <kabe sra-tohoku.co.jp> and
4229 Cliff Woolley <cliffwoolley yahoo.com>]
4231 *) Add a couple of GCC attribute tags to printf style functions.
4232 [Jon Travis <jtravis covalent.net>]
4234 *) Add the correct language tag for interoperation with the Taiwanese
4235 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
4237 *) Migrate the perchild MPM to use the new apr signal child, and
4238 APR thread functions. [Ryan Bloom]
4240 *) Close one copy of the CGI's stdout before creating the new process.
4241 The CGI will still have stdout, because we have already dup'ed it.
4242 This keeps Apache from waiting forever to send the results of a CGI
4243 process that has forked a long-lived child process.
4244 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4246 *) Remove the rest of the pthreads functions from the threaded MPM.
4247 This requires the APR support for a signal thread that was just
4250 *) Make mod_dir use a fixup for sending a redirect to the browser.
4251 Before this, we were using a handler, which doesn't make much
4252 sense, because the handler wasn't generating any data, it would
4253 either return a redirect error code, or DECLINED. This fits the
4254 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
4256 *) Make the threaded MPM use APR threads instead of pthreads.
4259 *) Get mod_tls to the point where it actually appears to work in all cases.
4262 *) implement --enable-modules and --enable-mods-shared for "all" and
4263 "most". [Greg Stein]
4265 *) Move the threaded MPM to use APR locks instead of pthread locks.
4268 *) Rename mpmt_pthread to threaded. This is more in line with the
4269 fact that mpmt_pthread shouldn't be using pthreads directly, and
4270 it is a smaller name that doesn't tie into anything.
4273 *) Rename the module structures so that the exported symbol matches
4274 the file name, and it is easier to automate the installation
4275 process (generating LoadModule directives from the module filenames).
4278 *) Remove the coalesce filter. With the ap_f* functions, this filter
4279 is no longer needed. [Ryan Bloom]
4281 Changes with Apache 2.0.11
4283 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
4284 added feature of allowing a uid/gid per child process. If no
4285 uid/gid is specified, then Perchild behaves exactly like dexter.
4288 *) Get perchild building again. [Ryan Bloom]
4290 *) Don't disable threads just because we are using the prefork MPM.
4291 If somebody wants to compile without threads, they must now add
4292 --disable-threads to the configure command line. [Ryan Bloom]
4294 *) Begin to move the calls to update_child_status into common code, so
4295 that each individual MPM does not need to update the scoreboard itself.
4298 *) Allow mod_tls to compile under Unix boxes where openssl has been
4299 installed to the system include files.
4300 [Gomez Henri <new-httpd slib.fr>]
4302 *) Cleanup the mod_tls configure process. This should remove any need
4303 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
4304 configure doesn't check that yet. [Ryan Bloom]
4306 *) Add a very early prototype of SSL support (in mod_tls.c). It is
4307 vital that you read modules/tls/README before attempting to build
4310 *) Fix a potential seg fault on all platforms. David Reid fixed this
4311 on BEOS, but the problem could happen anywhere, so we don't want
4312 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
4314 *) Add new LogFormat directive, %D, to log time it takes to serve a
4315 request in microseconds. [Bill Stoddard]
4317 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
4318 SetOutputFilter. This corresponds nicely with the other Set
4319 directives, which operate on containers while the Add* directives
4320 tend to work directly on extensions. [Ryan Bloom]
4322 *) Cleanup the header handling a bit. This uses the apr_brigade_*
4323 functions for the buffering so that we don't need to compute
4324 the length of the headers before we actually create the header
4325 buffer. [Ryan Bloom]
4327 *) Allow filters to buffer data using the ap_f* functions. These have
4328 become macros that resolve directly to apr_brigade_*.
4331 *) Get the Unix MPM's to do a graceful restart again. If we are going
4332 to register a cleanup with ap_cleanup_scoreboard, then we have to
4333 kill the cleanup with the same function, and that function can't be
4334 static. [Ryan Bloom]
4336 *) Install all required header files. Without these, it was not
4337 possible to compile some modules outside of the server.
4340 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
4341 forward from 1.3 to 2.0, we missed a single line, which broke regex
4342 aliases. [Ryan Bloom]
4344 *) We have a poor abstraction in the protocol. This is a temporary
4345 hack to fix the bug, but it will need to be fixed for real. If
4346 we find an error while sending out a custom error response, we back
4347 up to the first non-OK request and send the data. Then, when we send
4348 the EOS from finalize_request_protocol, we go to the last request,
4349 to ensure that we aren't sending an EOS to a request that has already
4350 received one. Because the data is sent on a different request than
4351 the EOS, the error text never gets sent down the filter stack. This
4352 fixes the problem by finding the last request, and sending the data
4353 with that request. [Ryan Bloom]
4355 *) Make the server status page show the correct restart time, and
4356 thus the proper uptime. [Ryan Bloom]
4358 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
4359 should reduce the amount of duplicate code that is required to
4360 create CGI processes.
4361 [Paul J. Reder <rederpj raleigh.ibm.com>]
4363 *) ap_new_connection() closes the socket and returns NULL if a socket
4364 call fails. Usually this is due to a connection which has been
4365 reset. [Jeff Trawick]
4367 *) Move the Apache version information out of httpd.h and into release.h.
4368 This is in preparation for the first tag with the new tag and release
4369 system. [Ryan Bloom]
4371 *) Begin restructuring scoreboard code to enable adding back in
4372 the ability to use IPC other than shared memory.
4373 Get mod_status working on Windows again. [Bill Stoddard]
4375 *) Make mod_status work with 2.0. This will work for prefork,
4376 mpmt_pthread, and dexter. [Ryan Bloom]
4378 *) Correct a typo in httpd.conf.
4379 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
4381 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
4383 *) Get the correct IP address if ServerName isn't set and we can't
4384 find a fully-qualified domain name at startup.
4385 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
4387 *) Make mod_cgid work with SuExec. [Ryan Bloom]
4389 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
4390 'extra' stat's for user/group since they should never occur, and now
4391 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
4392 volumes. [William Rowe]
4394 *) Adopt apr features to simplify mod_includes. This changes the
4395 behavior of the USER_NAME variable, unknown uid's are now reported
4396 as USER_NAME="<unknown>" rather than the old user#000 result.
4397 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
4399 *) Adopt apr features for simplifing mod_userdir, and accept the new
4400 Win32/OS2 exceptions without hiccuping. [William Rowe]
4402 *) Replace configure --with-optim option by using and saving the
4403 environment variable OPTIM instead. This is needed because configure
4404 options do not support multiple flags separated by spaces.
4407 *) Fix some byterange handling. If we get a byte range that looks like
4408 "-999999" where that is past the end of the file, we should return
4409 a PARTIAL CONTENT status code, and return the whole file as one big
4410 byterange. This matches the 1.3 handling now. [Ryan Bloom]
4412 *) Make the error bucket a real meta-data bucket. This means that the
4413 bucket length is 0, and a read returns NULL data. If one of these
4414 buckets is passed down after the headers are sent, this data will
4415 just be ignored. [Greg Stein]
4417 *) The prefork MPM wasn't killing child processes correctly if a restart
4418 signal was received while the process was serving a request. The child
4419 process would become the equivalent of a second parent process. If
4420 we break out of the accept loop, then we need to do die after cleaning
4421 up after ourselves. [Ryan Bloom]
4423 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
4424 restarts. [Ryan Bloom]
4426 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
4427 the most optimal APR_FINFO_wanted bits. This spares Win32 from
4428 performing very expensive owner, group and permission lookups
4429 and allows the server to function until these apr_finfo_t fields
4430 are implemented under Win32. [William Rowe]
4432 *) Support for typedsafe optional functions - that is functions exported by
4433 optional modules, which, therefore, may or may not be present, depending
4434 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
4435 for sample code. [Ben Laurie]
4437 *) filters can now report an HTTP error to the server. This is done
4438 by sending a brigade where the first bucket is an error_bucket.
4439 This bucket is a simple bucket that stores an HTTP error and
4440 a string. Currently the string is not used, but it may be needed
4441 to output an error log. The http_header_filter will find this
4442 bucket, and output the error text, and then return
4443 AP_FILTER_ERROR, which informs the server that the error web page
4444 has already been sent. [Ryan Bloom]
4446 *) If we get an error, then we should remove all filters except for
4447 those critical to serving a web page. This fixes a bug, where
4448 error pages were going through the byterange filter, even though
4449 that made no sense. [Ryan Bloom]
4451 *) Relax the syntax checking of Host: headers in order to support
4452 iDNS. PR#6635 [Tony Finch]
4454 *) Cleanup the byterange filter to use the apr_brigade_partition
4455 and apr_bucket_copy functions. This removes a lot of very messy
4456 code, and hopefully makes this filter more stable.
4459 *) Remove AddModule and ClearModuleList directives. Both of these
4460 directives were used to ensure that modules could be enabled
4461 in the correct order. That requirement is now gone, because
4462 we use hooks to ensure that modules are in the correct order.
4465 *) When SuExec is specified, we need to add it to the list of
4466 targets to be built. If we don't, then any changes to the
4467 configuration won't affect SuExec, unless 'make suexec' is
4468 specifically run. [Ryan Bloom]
4470 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4471 the APR_XTHREAD argument to open a file for consumption by
4472 parallel threads on win32. [William Rowe]
4474 *) Correct a bug in determining when we follow symlinks. The code
4475 expected a stat -1 result, not an apr_status_t positive error.
4476 Also check if the APR_FINFO_USER fields are valid before we
4477 follow the link. [William Rowe]
4479 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4480 mpm_common.c. These functions are only valid on some platforms,
4481 so they should not be in the main-line code. [Ryan Bloom]
4483 *) Remove ap_chdir_file(). This function is not thread-safe,
4484 and nobody is currently using it. [Ryan Bloom]
4486 *) Do not try to run make depend if there are no .c files in the
4487 current directory, doing so makes `make depend` fail.
4490 *) Update highperformance.conf to work with either prefork or
4491 pthreads mpms. [Greg Ames]
4493 *) Stop checking to see if this is a pipelined request if we know
4494 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4495 This keeps us from making an extra read call when serving a 1.0
4496 request. [Ryan Bloom and Greg Stein]
4498 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4499 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4500 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4502 *) Fix the RFC number mentioned when complaining about a missing
4503 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
4505 *) Fix an endless loop in ab which occurred when ab was posting
4506 and the server dropped the connection unexpectedly.
4509 *) Fix a segfault while handling request bodies in ap_http_filter().
4510 This problem has been seen with mod_dav usage as well as with
4511 requests where the body was just being discarded. [Jeff Trawick]
4513 *) Some adjustment on the handling and automatic setting (via
4514 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4515 add the capability to specify flags (NOTEST_CFLAGS and
4516 NOTEST_LDFLAGS) which are used to compile Apache, but
4517 not used during the configuration process. Useful for
4518 flags like "-Werror". [Jim Jagielski]
4520 *) Stop using environment variables to force debug mode or
4521 no detach. We now use the -D command line argument to
4522 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4523 [Greg Stein, Ryan Bloom]
4525 *) Change handlers to use hooks. [Ben Laurie]
4527 *) Stop returning copies of filenames from both apr_file_t and
4528 apr_dir_t. We pstrdup the filenames that we store in the
4529 actual structures, so we don't need to pstrdup the strings again.
4532 *) mod_cgi: Fix some problems where the wrong error value was being
4533 traced. [Jeff Trawick]
4535 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
4538 *) Add generic hooks. [Ben Laurie]
4540 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
4542 *) Fix a segfault caused by mod_ext_filter when the external filter
4543 program does not exist. [Jeff Trawick]
4545 *) Fix an output truncation error when on an HTTP >= 1.0 request an
4546 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
4547 was served through mod_charset_lite (or anything else that would
4548 create a transient bucket in this size range). ap_bucket_make_heap()
4549 silently failed (fixed), transient_setaside() discovered it, but
4550 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
4552 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
4553 is that some browsers send extra lines at the end of POST requests, and
4554 we don't want to delay sending data back to the user just because the
4555 browser isn't well behaved. [Ryan Bloom]
4557 *) Get SuEXEC working again. We can't send absolute paths to suExec
4558 because it refuses to execute those programs. SuEXEC also wasn't
4559 always recognizing configuration changes made using the autoconf
4562 *) Allow the buildconf process to find the config.m4 files in the correct
4563 order. Basically, we can now name config.m4 files as config\d\d.m4,
4564 and we will sort them correctly when inserting them into the build
4565 process. [Ryan Bloom]
4567 *) Get mod_cgid to use apr calls for creating the actual CGI process.
4568 This also allows mod_cgid to use ap_os_create_priviledged_process,
4569 thus allowing for SuExec execution from mod_cgid. Currently, we do
4570 not support everything that standard SuExec supports, but at least
4571 it works minimally now. [Ryan Bloom]
4573 *) Allow SuExec to be configured from the ./configure command line.
4576 *) Update some of the docs in README and INSTALL to reflect some of
4577 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
4579 *) If we get EAGAIN returned from the call to apr_sendfile, then we
4580 need to call sendfile again. This gets us serving large files
4581 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
4583 *) Get the support programs building cleanly again.
4584 [Cliff Woolley <cliffwoolley yahoo.com>]
4586 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
4587 current directory logic now backs up over bin/ to determine the
4588 server root from the Apache.exe path.
4590 *) Apache/Win32 now follows the standard conventions of mod_foo.so
4591 loadable modules, dynamic libs are all named libfoo.dll, and the
4592 makefile.win populates the include, lib and libexec directories.
4594 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
4595 Apache gets IPv6 listening sockets by default. Additionally, the
4596 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
4597 numeric address strings (e.g., "Listen [fe80::1]:8080").
4600 *) Modify the install directory layout. Modules are now installed in
4601 modules/. Shared libraries should be installed in libraries/, but
4602 we don't have any of those on Unix yet. All install directories
4603 are modifyable at configure time. [Ryan Bloom]
4605 *) Install all header files in the same directory on Unix. [Ryan Bloom]
4607 *) Get the functions in server/linked into the server, regardless of
4608 which modules linked into the server. This uses the same hack
4609 for Apache that we use for APR and apr-util to ensure all of the
4610 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
4611 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
4612 the scripts a bit easier.
4615 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
4616 on the query, and remove IPv4 dependencies. [Jeff Trawick]
4618 *) Get all of the auth modules to the point that they will install and
4619 be loadable into the server. Our new build/install mechanism expects
4620 that all modules will have a common name format. The auth modules
4621 didn't use that format, so we didn't install them properly.
4624 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
4625 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
4627 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
4629 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
4630 after the end of the response. [Ryan Bloom]
4632 *) Get byterange requests working with responses that do not have a
4633 content-length. Because of the way byterange requests work, we have to
4634 have all of the data before we can actually do the byterange, so we
4635 can compute the content-length in the byterange filter.
4638 *) Get exe CGI's working again on Windows.
4641 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
4642 they keep track of whether or not their post config hook has been
4643 called before. Instead of a static variable (which is replaced when
4644 the DSO is loaded a second time), use userdata in the process pool.
4647 Changes with Apache 2.0a9
4649 *) Win32 now requires perl to complete the final install step for users
4650 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
4651 and installs the conf, htdocs and htdocs/manual directories.
4654 *) Make mod_include use a hash table to associate directive tags with
4655 functions. This allows modules to implement their own SSI tags easily.
4656 The idea is simple enough, a module can insert it's own tag and function
4657 combination into a hash table provided by mod_include. While mod_include
4658 parses an SSI file, when it encounters a tag in the file, it does a
4659 hash lookup to find the function that implements that tag, and passes
4660 all of the relevant data to the function. That function is then
4661 responsible for processing the tag and handing the remaining data back
4662 to mod_include for further processing.
4663 [Paul J. Reder <rederpj raleigh.ibm.com>]
4665 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
4666 fewer parameters: the local and remote socket addresses were removed
4667 from the parameter list because all required information is available
4668 via the APR socket. [Jeff Trawick]
4670 *) Distribution directory structure reorganized to reflect a
4671 normal source distribution with external install targets.
4674 *) The MPMs that need multiple segments of shared memory now create
4675 two apr_shmem_t variables, one for each shared memory allocation.
4676 the problem is that we can't determine how much memory will be required
4677 for shared memory allocations once we try to allocate more than one
4678 variable. The MM code automatically aligns the shared memory allocations,
4679 so we end up needing to pad the amount of shared memory we want based
4680 on how many variables will be allocated out of the shared memory segment.
4681 It is just easier to create a second apr_shmem_t variable, and two
4682 shmem memory blocks.
4685 *) Cleanup the export list a bit. This creates a single unified list of
4686 functions exported by APR. The export list is generated at configure
4687 time, and that list is then used to generate the exports.c file.
4688 Because of the way the export list is generated, we only export those
4689 functions that are valid on the platform we are building on.
4692 *) Enable logging the cookie with mod_log_config
4693 [Sander van Zoest <sander covalent.net>]
4695 *) Fix a segfault in mod_info when it reaches the end of the configuration.
4698 *) Added lib/aputil/ as a placeholder for utility functions which are not
4699 specific to the Apache HTTP Server (but do not make sense with APR).
4700 The first utility is "apu_dbm": a set of functions to work with DBM
4701 files. This first version can be compiled for SDBM or GDBM databases.
4704 *) Complete re-write of mod_include. This makes mod_include a filter that
4705 uses buckets directly. This has now served the FAQ correctly.
4706 [Paul Reder <rederpj raleigh.ibm.com>]
4708 *) Allow modules to specify the first filter in a sub_request when
4709 making the sub_request. This keeps modules from having to change the
4710 output_filter immediately after creating the sub-request, and therefore
4711 skip the sub_req_output_filter. [Ryan Bloom]
4713 *) Update ab to accept URLs with IPv6 literal address strings (in the
4714 format described in RFC 2732), and to build Host header fields in
4715 the same format. This allows IPv6 literal address strings to be
4716 used with ab. This support has been tested against Apache 1.3 with
4717 the KAME patch, but Apache 2.0 does not yet work with this format
4718 of the Host header field. [Jeff Trawick]
4720 *) Accomodate an out-of-space condition in the piped logs and the
4721 rotatelogs.c code, and no longer churn log processes for this
4722 condition. [Victor J. Orlikowski]
4724 *) Add support for partial writes with apr_sendfile() to core_output_filter.
4727 Changes with Apache 2.0a8
4729 *) Add a directive to mod_mime so that filters can be associated with
4733 *) Get multi-views working again. We were setting the path_info
4734 field incorrectly if we couldn't find the specified file.
4737 *) Fix 304 processing. The core should never try to send the headers
4738 down the filter stack. Always, just setup the table in the request
4739 record, and let the header filter convert it to data that is ready
4743 *) More fixes for the proxy. There are still bugs in the proxy code,
4744 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
4748 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
4751 *) APR: Add new apr_getopt_long function to handle long options.
4752 [B. W. Fitzpatrick <fitz red-bean.com>]
4754 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
4755 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
4756 hostname resolution/address string parsing and building
4757 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
4758 of one of the apr_sockaddr_t structures for a socket. Change
4759 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
4761 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
4762 I have proxied pages with it, cleanup will commence soon.
4765 *) Make the proxy work with filters. This isn't perfect, because we
4766 aren't dealing with the headers properly. [Ryan Bloom]
4768 *) Do not send a content-length iff the C-L is 0 and this is a head
4769 request. [Ryan Bloom]
4771 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
4772 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
4774 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
4776 *) Get the default_handler to stop trying to deal with HEAD requests.
4777 The idea is to let the content-length filter compute the C-L before
4778 we try to send the data. If we can get the C-L correctly, then we
4779 should send it in the HEAD response.
4782 *) The Header filter can now determine if a body should be sent based
4783 on r->header_only. The general idea of this is that if we delay
4784 deciding to send the body, then we might be able to compute the
4785 content-length correctly, which will help caching proxies to cache
4786 our data better. Any handler that doesn't want to try to compute
4787 the content-length can just send an EOS bucket without data and
4788 everything will just work.
4791 *) Add the referer to the error log if one is available.
4792 [Markus Gyger <mgyger itr.ch>]
4794 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
4795 change, the root of the configuration tree has been exposed to modules
4797 [Ryan Morgan <rmorgan covalent.net>]
4799 *) Get the core_output_filter to use the bucket interface directly.
4800 This keeps us from calling the content-length filter multiple times
4801 for a simple static request.
4804 *) We are sending the content-type correctly now.
4805 [Ryan Bloom and Will Rowe]
4807 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
4808 a bogus bytes-sent value when the only thing being sent was trailers
4809 and writev() returned an error (or EAGAIN). [Jeff Trawick]
4811 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
4812 hints file to determine which platforms define
4813 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
4816 *) APR: add apr_get_home_directory() [Jeff Trawick]
4818 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
4820 *) Not all platforms have INADDR_NONE defined by default. Apache
4821 used to make this check and define INADDR_NONE if appropriate,
4822 but APR needs the check too, and I suspect other applications will
4823 as well. APR now defines APR_INADDR_NONE, which is always a valid
4824 value on all platforms.
4825 [Branko Èibej <brane xbc.nu>]
4827 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
4828 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
4830 *) Relax the syntax checking of Host: headers in order to support
4831 iDNS. PR#6635 [Tony Finch]
4833 *) When reading from file buckets we convert to an MMAP if it makes
4834 sense. This also simplifies the default handler because the
4835 default handler no longer needs to try to create MMAPs.
4838 *) BUFF has been removed from the main server. The BUFF code will remain
4839 in the code until it has been purged from the proxy module as well.
4842 *) Byteranges have been completely re-written to be a filter. This
4843 has been tested, and I believe it is working correctly, but it could
4844 doesn't work for the Adobe Acrobat plug-in. The output almost matches
4845 the output from 1.3, the only difference being that 1.3 includes
4846 a content-length in the response, and this does not.
4849 *) APR read/write functions and bucket read functions now operate
4850 on unsigned integers, instead of signed ones. It doesn't make
4851 any sense to use signed ints, because we return the error codes,
4852 so if we have an error we should report 0 bytes read or written.
4855 *) Always compute the content length, whether it is sent or not.
4856 The reason for this, is that it allows us to correctly report
4857 the bytes_sent when logging the request. This also simplifies
4858 content-length filter a bit, and fixes the actual byte-reporing
4859 code in mod_log_config.c
4862 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
4863 it says, because it was only used by EOS and FLUSH buckets. Since
4864 neither of those are required at the end of a brigade, this was
4865 really signifying FLUSH_THE_DATA, but that can be determined better
4866 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
4867 buckets now return a length of 0, which is actually the amount of data
4868 read, so they make more sense.
4871 *) Allow the core_output_filter to save some data past the end of a
4872 request. If we get an EOS bucket, we only send the data if it
4873 makes sense to send it. This allows us to pipeline request
4874 responses. As a part of this, we also need to allocate mmap
4875 buckets out of the connection pool, not the request pool. This
4876 allows the mmap to outlive the request.
4879 *) Make blocking and non-blocking bucket reads work correctly for
4880 sockets and pipes. These are the only bucket types that should
4881 have non-blocking reads, because the other bucket types should
4882 ALWAYS be able to return something immediately.
4885 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
4886 server, but use Ctrl+Break to initiate a graceful restart
4887 instead of duplicating behavior. [John Sterling]
4889 *) Patch mod_autoindex to set the Last-Modified header based on
4890 the directory's mtime, and add the ETag header. [William Rowe]
4892 *) Merge the 1.3 patch to add support for logging query string in
4893 such a way that "%m %U%q %H" is the same as "%r".
4896 *) Port three log methods from mod_log_config 1.3 to 2.0:
4897 CLF compliant '-' byte count, method and protocol.
4900 *) Add a new LogFormat directive, %c, that will log connection
4901 status at the end of the response as follows:
4902 'X' - connection aborted before the response completed.
4903 '+' - connection may be kept-alive by the server.
4904 '-' - connection will be closed by the server.
4907 *) Expand APR for WinNT to fully accept and return utf-8 encoded
4908 Unicode file names and paths for Win32, and tag the Content-Type
4909 from mod_autoindex to reflect that charset if the the feature
4910 macro APR_HAS_UNICODE_FS is true. [William Rowe]
4912 *) Compute the content length (and add appropriate header field) for
4913 the response when no content length is available and we can't use
4914 chunked encoding. [Jeff Trawick]
4916 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
4917 so that content input filters get dechunked data when using
4918 the default handler. Also removed REQUEST_CHUNKED_PASS.
4921 *) Add mod_ext_filter as an experimental module. This module allows
4922 the administrator to use external programs as filters. Currently,
4923 only filtering of output is supported. [Jeff Trawick]
4925 *) Most Apache functions work on EBCDIC machines again, as protocol
4926 data is now translated (again). [Jeff Trawick]
4928 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
4929 the EBCDIC support. They are noops on ASCII machines, so this
4930 type of translation doesn't have to be surrounded by #ifdef
4931 CHARSET_EBCDIC. [Jeff Trawick]
4933 *) Fix mod_include. tag commands work again, and the server will
4934 send the FAQ again. This also allows mod_include to set aside
4935 buckets that include partial buckets.
4936 [Ryan Bloom and David Reid]
4938 *) Add suexec support back. [Manoj Kasichainula]
4940 *) Lingering close now uses the socket directly instead of using
4941 BUFF. This has been tested, but since all we can tell is that it
4942 doesn't fail, this needs to be really hacked on.
4945 *) Allow filters to modify headers and have those headers be sent to
4946 the client. The idea is that we have an http_header filter that
4947 actually sends the headers to the network. This removes the need
4948 for the BUFF to send headers.
4951 *) Charset translation: mod_charset_lite handles translation of
4952 request bodies. Get rid of the xlate version of ap_md5_digest()
4953 since we don't compute digests of filtered (e.g., translated)
4954 response bodies this way anymore. (Note that we don't do it at
4955 all at the present; somebody needs to write a filter to do so.)
4958 *) Input filters and ap_get_brigade() now have a input mode parameter
4959 (blocking, non-blocking, peek) instead of a length parameter.
4962 *) Update the mime.types file to the registered media types as
4963 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
4966 *) Namespace protect some macros declared in ap_config.h
4969 *) Support HTTP header line folding with input filtering.
4972 *) Mod_include works again. This should still be re-written, but at
4973 least now we can serve an SHTML page again.
4976 *) Begin to remove BUFF from the core. Currently, we keep a pointer
4977 to both the BUFF and the socket in the conn_rec. Functions that
4978 want to use the BUFF can, functions that want to use the socket,
4979 can. They point to the same place.
4982 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
4983 [Tomas "Ögren" <stric ing.umu.se>]
4985 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
4986 associated pool goes away. (APR pipes on OS/2 were already had this
4987 logic.) This resolvs a fatal file descriptor leak with CGIs.
4990 *) The final line of the config file was not being read if there was
4991 no \n at the end of it. This was caused by apr_fgets returning
4992 APR_EOF even though we had read valid data. This is solved by
4993 making cfg_getline check the buff that was returned from apr_fgets.
4994 If apr_fgets return APR_EOF, but there was data in the buf, then we
4995 return the buf, otherwise we return NULL.
4998 *) Piped logs work again in the 2.0 series.
5001 *) Restore functionality broken by the mod_rewrite security fix:
5002 rewrite map lookup keys and default values are now expanded
5003 so that the lookup can depend on the requested URI etc.
5004 PR #6671 [Tony Finch]
5006 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
5007 security bug in some mass virtual hosting configurations
5008 that can allow a remote attacker to retrieve some files
5009 on the system that should be inaccessible. [Tony Finch]
5011 *) Add a pool bucket type. This bucket is used for data allocated out
5012 of a pool. If the pool is cleaned before the bucket is destroyed, then
5013 the data is converted to a heap bucket, allowing it to survive the
5017 *) Add a flush bucket. This allows modules to signal that the filters
5018 should all flush whatever data they currently have. There is no way
5019 to actually force them to do this, so if a filter ignores this bucket,
5020 that's life, but at least we can try with this.
5023 *) Add an output filter for sub-requests. This filter just strips the
5024 EOS bucket so that we don't confuse the main request's core output
5025 filter by sending multiple EOS buckets. This change also makes sub
5026 requests start to send EOS buckets when they are finished.
5029 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
5030 makes ap_bucket_destroy a return void, which is okay because it
5031 used to always return APR_SUCCESS, and nobody ever checked its
5032 return value anyway.
5033 [Cliff Woolley <cliffwoolley yahoo.com>]
5035 *) Remove the index into the bucket-type table from the buckets
5036 structure. This has now been replaced with a pointer to the
5037 bucket_type. Also add some macros to test the bucket-type.
5040 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
5041 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
5042 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
5043 All _VAR_ flavors changes to _DATA to be absolutely clear.
5046 *) Add support for /, //, //servername and //server/sharename
5047 parsing of <Directory> blocks under Win32 and OS2.
5048 [Tim Costello, William Rowe, Brian Harvard]
5050 *) Remove the function pointers from the ap_bucket type. They have been
5051 replaced with a global table. Modules are allowed to register bucket
5052 types and use then use those buckets.
5055 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
5056 once we finish writing the request body to the cgi child process;
5057 otherwise, the client doesn't hit EOF on stdin. Small request bodies
5058 worked without this change (for reasons I don't understand), but large
5059 ones didn't. [Jeff Trawick]
5061 *) Remove file bucket specific information from the ap_bucket type.
5062 This has been moved to a file_bucket specific type that hangs off
5063 the data pointer in the ap_bucket type.
5066 *) Input filtering now has a third argument. This is the amount of data
5067 to read from lower filters. This argument can be -1, 0, or a positive
5068 number. -1 means give me all the data you have, I'll deal with it and
5069 let you know if I need more. 0 means give me one line and one line
5070 only. A positive number means I want no more than this much data.
5072 Currently, only 0 and a positive number are implemented. This allows
5073 us to remove the remaining field from the conn_rec structure, which
5077 *) Big cleanup of the input filtering. The goal is that http_filter
5078 understands two conditions, headers and body. It knows where it is
5079 based on c->remaining. If c->remaining is 0, then we are in headers,
5080 and http_filter returns a line at a time. If it is not 0, then we are
5081 in body, and http_filter returns raw data, but only up to c->remaining
5082 bytes. It can return less, but never more.
5083 [Greg Ames, Ryan Bloom, Jeff Trawick]
5085 *) mod_cgi: Write all of the request body to the child, not just what
5086 the kernel would accept on the first write. [Jeff Trawick]
5088 *) Back out the change that moved the brigade from the core_output_filters
5089 ctx to the conn_rec. Since all requests over a given connection
5090 go through the same core_output_filter, the ctx pointer has the
5094 *) Fix another bug in the send_the_file() read/write loop. A partial
5095 send by apr_send would cause unsent data in the read buffer to
5096 get clobbered. Complete making send_the_file handle partial
5097 writes to the network.
5100 *) Fix a couple of type fixes to allow compilation on AIX again
5101 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
5103 *) Fix bug in send_the_file() which causes offset to be ignored
5104 if there are no headers to send.
5107 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
5108 filter. Useful for supporting Windows 9* with a binary
5109 compiled on Windows NT.
5112 Changes with Apache 2.0a7
5114 *) Reimplement core_output_filter to buffer/save bucket brigades
5115 across multiple calls to the core_filter. The brigade will be
5116 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
5117 thresholds are hit or the EOS bucket is received.
5120 *) Create experimental filter (buffer_filter) that coalesces bytes
5121 into one large buffer before invoking the next filter in the
5122 chain. This filter is particularly useful with the current
5123 implementation of mod_autoindex when it inserted above the
5124 chunk_filter. mod_autoindex generates a lot of brigades that
5125 containing buckets holding just a few bytes each. The
5126 buffer_filter coalesces these buckets into a single large bucket.
5129 *) Add apr_sendfile() support into the core_output_filter.
5132 *) Add apr_sendv() support into the core_output_filter.
5135 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
5136 [Mike Abbott <mja sgi.com>]
5138 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
5139 make much sense, because Apache uses buckets instead of BUFFs now.
5142 *) send_the_file now falls back to a read/write loop on platforms that
5143 do not have sendfile.
5144 [Ryan Bloom and Brian Havard]
5146 *) Install apachectl correctly, and substitute the proper values so
5147 that it works again. [Ryan Bloom]
5149 *) Better(??) handle platforms that lack sendfile().
5152 *) APR now has UUID generation/formatting/parsing support.
5155 *) Begin the http_filter. This is an input filter that understands
5156 the absolute basic amount required to parse an HTTP Request. The
5157 goal is to be able to split headers from request body before passing
5158 the data back to the other filters.
5161 *) Bring forward from 1.3.13 the config directory implementation
5164 *) install apxs if it is created
5167 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
5168 conversions. [William Rowe]
5170 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
5171 ap_add_output_filter(). [Jeff Trawick]
5173 *) Multiple build and configuration fixes
5176 -add datadir and localstatedir substitutions
5178 -fix logfilename misspelling
5179 -fix evaluation of installation dir variables and
5180 -replace $foobar by $(foobar) to be usefull in the makefile
5184 -add rules for cross-compiling in rules.mk. Okay, rule to check for
5185 $CC_FOR_BUILD is still missing
5186 -use CHECK_TOOL instead of CHECK_PROG for ranlib
5187 -add missing "AR=@AR@" to severaly Makefile.in's
5188 -cache result for "struct rlimit"
5189 -compile all helper programs with native and cross compiler
5190 and use the native version to generate header file
5191 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5193 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
5195 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5197 *) Fix a bug where a client which only sends \n to delimit header
5198 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
5199 message. Start working on ebcdic co-existance with input
5201 [William Rowe, Greg Ames]
5203 *) If mod_so is enabled in the server always create libexec, even
5204 if there are no modules installed in this directory. This is a
5205 requirement for APXS to work correctly.
5208 *) Connection oriented output filters are now stored in the
5209 conn_rec instead of the request_rec. This allows us to add the
5210 output filter in the pre-connection phase instead of the
5211 post_read_request phase, which keeps us from trying to write an
5212 error page before we have a filter to write to the network.
5213 [Ryan Bloom, Jeff Trawick, and Greg Ames]
5215 *) Cleaning up an mmap bucket no longer deletes the mmap. An
5216 mmap can be used across multiple buckets (default_handler with
5217 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
5218 the mmap itself can't be associated with the bucket.
5221 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
5224 *) Radical surgery to improve mod_isapi support under Win32.
5225 Includes a number of newer ServerSupportFunction calls, support
5226 for ReadClient (in order to retrieve POSTs greater than 48KB),
5227 and general bug fixes to more reliably load ISAPI .dll's and
5228 prevent leaking handle resources. Note: There are still
5229 discrepancies between IIS's and Apache's ServerVariables, and
5230 async calls are still not supported. Additional warnings are
5231 logged to facilitate debugging of unsupported ISAPI calls.
5234 *) Add input filtering to Apache. The basic idea for the input
5235 filters is the same as the ideas for output filters. The biggest
5236 difference is that instead of calling ap_pass_brigade, ap_get_brigade
5237 should be called, and the order of execution for the filter itself is
5238 different. When writing an output filter, a brigade is passed in,
5239 and filters operate directly on that brigade, when done, they call
5240 ap_pass_brigade. Input filters are the exact opposite. Because input
5241 is not a push operation, filters first call ap_get_brigade. When this
5242 function returns, the input filter will be left with a valid brigade.
5243 The input filter should then operate on the brigade, and return.
5246 *) Fix building on BSD/OS using its native make. The build system
5247 falls back to the BSD .include directive on that host platform.
5250 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
5251 SHA1 and plaintext password encodings. Make feature tests a
5252 bit more flexible. [William Rowe]
5254 *) Charset translation: mod_charset_lite handles output content
5255 translation in a filter. mod_charset_lite no longer ignores
5256 subrequests. A bunch of cruft related to BUFF's support for
5257 translating request and response bodies was removed.
5260 *) Move the addition of the CORE filter to the post_read_request
5261 hook in http_core.c. This removes the need to add the filter in
5262 multiple places and allows for an SSL module to be added much
5263 simpler. [Ryan Bloom]
5265 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
5266 Fix a security problem that affects certain configurations of
5267 mod_rewrite. If the result of a RewriteRule is a filename that
5268 contains expansion specifiers, especially regexp backreferences
5269 $0..$9 and %0..%9, then it may be possible for an attacker to
5270 access any file on the web server. [Tony Finch]
5272 *) Fix a bug where errors that are detected during early request parsing
5273 don't produce visible HTTP error messages at the browser, because
5274 the core_filter wasn't present. [Greg Ames]
5276 *) Provide apr_socklen_t as a portability aid.
5277 [Victor J. Orlikowski]
5279 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
5280 as well as a comment arg to the add, adduser and update cmds.
5281 update allows the user to clear or preserve pw/groups/comment.
5282 Fixed a bug in dbmmanage that prevented the check option from
5283 parsing a password followed by :group... text. Corrected the
5284 seed calcualation for Win32 systems, and added -lsdbm support.
5287 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
5290 *) Avoid a segfault when parsing .htaccess files. An
5291 uninitialized tree pointer was passed to ap_build_config().
5294 *) Change the way that inet_addr & inet_network are checked for
5295 in APR's configure process to allow BeOS BONE to correctly
5296 find them. With this change BeOS BONE now builds from source
5297 with no problems. [David Reid]
5299 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
5300 the end of the parameters to execve() was stored in the wrong
5301 location, overlaying the storage beyond the newargs[] array and
5302 also passing uninitialized storage to execve(), which would
5303 sometimes fail with EFAULT. [Jeff Trawick]
5305 *) Fix a bug parsing configuration file containers. With a sequence
5306 like this in the config file
5308 <IfModule mod_kilroy.c>
5311 <IfModule mod_lovejoy.c>
5316 the second container would be terminated at the blank line due to
5317 sediment in the buffer from reading the prior </IfModule> and an
5318 error message would be generated for the real </IfModule> for the
5319 second container. Also due to this problem, any two characters
5320 could be used for "</" in the close of a container.
5323 *) ap_add_filter prototype changed to remove the ctx pointer. The
5324 pointer still remains in the filter structure, but it can not be
5325 a part of the ap_add_filter prototype. The reason is that when
5326 the core uses AddFilter to add a filter to the stack it doesn't
5327 know how to allocate the ctx pointer, or even how much memory should
5328 be allocated. The filters will have to be responsible for allocating
5329 the ctx memory when they need it.
5332 *) Add an AddFilter directive. This directive takes a list of filters
5333 that should be activated for the requested resource.
5336 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
5337 some other platforms). [Jeff Trawick]
5339 *) Modify mod_include to be a filter. Currently, it has only been tested
5340 on actual files, but it should work for CGI scripts too.
5343 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
5344 writes. apr_flush() for Unix: handle interrupted writes.
5347 *) NameVirtualHost can now take "*" as an argument instead of
5348 an IP address. This allows you to create a purely name-based
5349 virtual hosting server that does not have any IP addresses in
5350 the configuration file and which ignores the local address
5351 of any connections. PR #5595, PR #4455 [Tony Finch]
5353 *) Fix some compile warnings in mod_mmap_static.c
5354 [Mike Abbott <mja sgi.com>]
5356 *) Fix chunking problem with CGI scripts. The general problem was that
5357 the CGI modules were adding an EOS bucket and then the core added an
5358 EOS bucket. The chunking filter finalizes the chunked response when it
5359 encounters an EOS bucket. Because two EOS buckets were sent, we
5360 finalized the response twice. The fix is to make sure we only send one
5361 EOS, by utilizing a flag in the request_rec.
5364 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
5365 and Win32. Previously, the first read from an apr_file_t set up via
5366 apr_put_os_file() would return a '\0'. [Jeff Trawick]
5368 *) Mod_cgid now creates a single element bucket brigade, with a pipe
5369 bucket, instead of using BUFF's and ap_r*.
5372 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
5373 [Mike Abbott <mja sgi.com>]
5375 *) Remove ap_bopenf from buff code. This required modifying the file_cache
5376 code to use APR file's directly instead of going through BUFFs.
5379 *) Fix compile break on some platforms for mod_mime_magic.c
5380 [John K. Sterling <sterling covalent.net>]
5382 *) Fix merging of AddDefaultCharset directive.
5383 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
5385 *) Minor revamp of the rlimit sections of code. We now test
5386 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
5387 is now "available" even if the platform doesn't support
5388 the rlimit family (it's just a noop though). [Jim Jagielski]
5390 *) Migrate the pre-selection of which MPM to use for specific
5391 platforms to hints.m4, which contains (or should contain)
5392 all platform specific "hints". [Jim Jagielski]
5394 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
5397 *) Add tables with non-string/binary values to APR.
5400 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
5403 *) Update PCRE to version 3.2. [Ryan Bloom]
5405 *) Change the way buckets' destroy functions are called so that
5406 they can be more directly used when changing the type of a
5407 bucket in place. [Tony Finch]
5409 *) Add generic support for reference-counting the resources used by
5410 buckets, and alter the HEAP and MMAP buckets to use it. Change
5411 the way buckets are initialised to support changing the type of
5412 buckets in place, and use it when setting aside TRANSIENT buckets.
5413 Change the implementation of TRANSIENT buckets so that it can be
5414 mostly shared with IMMORTAL buckets, which are now implemented.
5417 Changes with Apache 2.0a6
5419 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
5421 *) Add a chunking filter to Apache. This brings us one step closer
5422 to removing BUFF. [Ryan Bloom]
5424 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
5425 added to the stack is the last filter to be called. [Ryan Bloom]
5427 *) Apache 2.0 has been completely documented using Scandoc. The
5428 docs can be generated by running 'make docs'. [Ryan Bloom]
5430 *) Add filtered I/O to Apache. This is based on bucket brigades,
5431 Currently the buckets still use BUFF under the covers, but that
5432 should change quickly. The only currently written filter is the
5433 core filter which just calls ap_bwrite. [The Apache Group]
5435 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
5436 built with thread support. [Jeff Trawick]
5438 *) Abort configuration if --with-layout was specified and there's
5439 no layout definition file. [Ken Coar]
5441 *) Add support for '--with-port=n' option to configure. [Ken Coar]
5443 *) Add support for extension methods for the Allow response header
5444 field, and an API routine for accessing r->allowed and the
5445 list of extension methods in a unified manner. [Ken Coar]
5447 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5448 [Rob Simonson <simo us.ibm.com>]
5450 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5451 APACHE_XLATE builds. [Jeff Trawick]
5453 *) A configuration file parsing problem was fixed. When the
5454 configuration file started with an IfModule/IfDefine container,
5455 only the last statement in the container would be retained.
5458 Changes with Apache 2.0a5
5460 *) Perchild is serving pages after passing them to different child
5461 processes. There are still a lot of bugs, but this does work. I
5462 have made requests against the same installation of Apache, and had
5463 different servers use different user IDs to serve the responses.
5464 This change moves to using socketpair instead of an AF_UNIX socket.
5467 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5468 It can't seem to pass between child processes yet, but I think we
5469 are closer now than before. This moves us back to using Unix
5470 Domain Sockets. [Ryan Bloom]
5472 *) libapr functions and types renamed with apr_ prefix.
5473 #include "apr_compat.h" for 1.3.x backwards compat
5476 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5477 return the right information on the local socket address.
5478 [Gregory Nicholls <gnicholls level8.com>]
5480 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5481 [Gregory Nicholls <gnicholls level8.com>]
5483 *) Add an option to not detach from the controlling terminal without
5484 going into single process mode. This allows for much easier
5485 debugging of the process startup code. [Ryan Bloom]
5487 *) ab: don't use perror() to report the failure of an APR function.
5490 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5491 scoreboard on graceful restarts.
5494 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5495 An invalid ap_proc_t was passed to ap_create_process().
5498 *) Allow modules to register filters. Those filters are still
5499 never called, but this is a step in the right direction.
5500 [Ryan Bloom and Greg Stein]
5502 *) Register the mod_cgid daemon process for cleanup so that it is
5503 killed at termination if it does not die when the parent gets
5504 SIGTERM. This change is to fix occasional problems where the
5505 process stays around. Bugs in similar logic in mod_rewrite and
5506 mod_include were also fixed. [Jeff Trawick]
5508 *) Fix a bug in the time handling. Basically, we were imploding a time
5509 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5510 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5511 uses those two fields to adjust the time value. Because of the HTTP
5512 spec, both of those values can be zero'ed out safely. This fixes
5513 the bug correctly. [Ryan Bloom]
5515 *) Fix a couple of place in the Windows code where the wrong error
5516 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
5518 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5520 *) Added the APR_EOL_STR macro for platform dependent differences in
5521 logfiles and other raw text (such as all APR files). Fixes logfiles
5522 not terminated with cr/lf sequences in Win32. [William Rowe]
5524 *) Move all strings functions in APR to src/lib/apr/strings and create
5525 apr_strings.h for the prototypes. [Ryan Bloom]
5527 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5528 to repeat the syscall until we stop getting EINTR. I noticed a
5529 related problem at termination (SIGTERM) on FreeBSD when using
5530 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5531 implementation work properly with child init. Previously, ap_lock()
5532 was essentially a no-op because all children were using different
5533 locks and thus nobody ever blocked. [Jeff Trawick]
5535 *) The htdocs/ tree has been moved out of the CVS source tree into
5536 a separate area for easier development. This has NO EFFECT on
5537 end-users or Apache installations. [Ken Coar]
5539 *) Integrate the mod_dav module for WebDAV protocol handling. This
5540 adds the dav and dav_fs modules, the SDBM library, and additional
5541 XML handling utilities. [Greg Stein]
5543 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
5546 *) Update the lib/expat-lite/ library (bring forward changes from
5547 the Apache 1.3 repository). [Greg Stein]
5549 *) If sizeof(long long) == sizeof(long), then prefer long in APR
5550 configure.in. [Dave Hill <ddhill zk3.dec.com>]
5552 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
5553 machines where sendfile is detected, but nobody has written ap_sendfile.
5554 [Dave Hill <ddhill zk3.dec.com>]
5556 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
5558 *) ab would start up more connections than needed, then quit when the
5559 desired number were finished. Also fixed a logic error involving
5560 ab keepalives. [Victor J. Orlikowski]
5562 *) WinNT: Implement non-blocking pipes with timeouts to communicate
5563 with CGIs. Apache 2.0a4 had non-blocking pipes but without
5564 timeouts (i.e, if a timeout was specified, the pipe reverted to
5565 a full blocking pipe). Now the behaviour is more in line with
5566 Unix non-blocking pipes.
5569 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
5570 cache open file handles along with accept socket reuse enables
5571 Apache 2.0 to serve non-keepalive requests for static files at
5572 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
5573 and Apache 2.0 will serve almost 1200 rps on my system).
5576 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
5577 supports two config directives, mmapfile (same behavious as
5578 mod_mmap_static) and cachefile. Use the cachefile directive
5579 to cache open file handles. This directive only works on systems
5580 that have implemented the ap_sendfile API. cachefile works today
5581 on Windows NT, but has not been tested on any flavors of Unix.
5584 *) Cleanup the configuration. With the last few changes the
5585 configuration process automatically:
5586 inherits information about how to build from APR. Allowing
5587 APR to inform Apache that it should or should not use -ldl
5589 Detects which mod_cgi should be used mod_cgi or mod_cgid,
5590 based on the threading model
5592 Apache calls APR's configure process before finishing it's
5593 configuration processing, allowing for more information flow
5598 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
5599 with non-zero argument makes the socket non-blocking. BeOS and
5600 OS/2 already worked this way. [Jeff Trawick]
5602 *) ap_close() now calls ap_flush() for buffered files, so write
5603 operations work a whole lot better on buffered files.
5606 *) Fix error messages issued from MPMs which explain where to change
5607 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
5610 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
5611 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
5612 now the way that the blocking state of a pipe is manipulated.
5613 ap_block_pipe() is gone. [Jeff Trawick]
5615 *) Correct the problem where the only local host name that the IP stack
5616 can discover are 'undotted' private names. If no fully qualified
5617 domain name can be identified, the default ServerName will be set to
5618 the machine's IP address string. A warning is always provided if the
5619 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
5621 *) Repair problems with config file processing which caused segfault
5622 at init when virtual hosts were defined and which caused ServerName to
5623 be ignored when there was no valid DNS setup. [Jeff Trawick]
5625 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
5627 *) Add ap_sendfile implementation for AIX
5628 [Victor J. Orlikowski]
5630 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
5631 apr_network_io.h, and apr_thread_proc.h.
5632 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
5634 *) Bring the allocation and pool debugging code back into a working
5635 state. This will need to be tested as so far it's only been used on
5638 *) Change configuration command setup to be properly typesafe when in
5639 maintainer mode. Note that this requires a compiler that can initialise
5640 unions. [Ben Laurie]
5642 *) Turn on buffering for config file reads. Part of this was to
5643 repair buffered I/O support in Unix and implement buffered
5644 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
5646 *) Win32: Fix problem where UTC offset was not being set correctly
5647 in the access log. Problem reported on news group by Jerry Baker.
5650 *) Fix segfault when reporting this type of syntax error:
5651 "</container> without matching <container> section", where
5652 container is VirtualHost or Directory or whatever.
5655 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
5656 Prevent the source code for CGIs from being revealed when
5657 using mod_vhost_alias and the CGI directory is under the document root
5658 and a user makes a request like http://www.example.com//cgi-bin/cgi
5659 as reported in <news:960999105.344321 ernani.logica.co.uk>
5662 *) Add support for the new Beos NetwOrking Environment (BONE)
5665 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
5666 final input char is incomplete; ap_bwrite_xlate() now handles
5667 incomplete final input chars. [Jeff Trawick]
5669 *) Yet another update to saferead/halfduplex stuff -- need to ensure
5670 that a bhalfduplex call occurs before logging or else DNS and
5671 such can delay the last packet of the response. [Dean Gaudet]
5673 *) Some syscall reduction in APR on unix -- don't seek when setting
5674 up an mmap; and don't fcntl() more than once per socket.
5677 *) When mod_cgid is started as root, the cgi daemon now switches
5678 to the configured User/Group (like other httpd processes)
5679 instead of continuing as root. [Jeff Trawick]
5681 *) The prefork MPM now uses an APR lock for the accept() mutex.
5682 It has not been getting a lock at all recently. httpd -V now
5683 displays APR's selection of the lock mechanism instead of the
5684 symbols previously respected by prefork. [Jeff Trawick]
5686 *) Change the mmap() feature test to check only for existence.
5687 The previous check required features not used by Apache.
5690 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
5691 sometimes mangled. The len parm to accept() was not
5692 initialized, leading sometimes to an endless loop of failed
5693 accept() calls on OS/390 and anywhere else that failed the call
5694 if the len was negative. Use <sys/un.h> for struct sockaddr_un
5695 instead of declaring it ourselves to fix a compilation problem
5696 on Solaris. [Jeff Trawick]
5698 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
5700 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
5702 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
5704 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
5705 initialization if ALLOC_DEBUG is defined; no known symptom
5706 otherwise. [Jeff Trawick]
5708 *) Fix typo in configure script when checking for mod_so. bash
5709 doesn't seem to have a problem but /bin/sh on Solaris does.
5710 Symptom: "./configure: test: unknown operator =="
5713 *) Rebind the Win32 NT and 9x services control into the MPM.
5714 All console, WinNT SCM and Win9x pseudo-service control code is
5715 now wrapped within the WinNT MPM.
5718 *) Make a copy of getenv("PATH") before storing for later use. Some
5719 getenv() implementations use the same storage for successive calls.
5720 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
5722 *) Server Tokens work in 2.0 again. This also propogates the change
5723 to allow just the product name in the server string using
5727 Changes with Apache 2.0a4
5729 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
5730 won't need to call it. [Greg Ames, Jeff Trawick]
5732 *) Move pre_config hook call to between configuration read and config
5733 tree walk. This allows all modules to implement pre_config hooks
5734 and know that they will be called at an appropriate time.
5737 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
5740 *) Add pre-config hooks back to all modules.
5743 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
5744 ContentDigest enabled and we can't/don't mmap the file.
5747 *) We now report the correct line number for syntax errors in config
5748 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
5750 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
5751 related bugs, and changed shmem/locking to use apr API. Shared-mem
5752 is currently disabled, however, because of problems with graceful
5753 restarts. [Ronald Tschalär]
5755 *) Fix corruption of IFS variable in --with-module= handling.
5756 Depending on the user's shell or customization thereof, there
5757 would be errors generating ap_config_auto.h later in the configure
5758 procedure. [Jeff Trawick]
5760 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
5761 isn't used (as in 1.3), except that on Unix it is now logged via
5762 ap_log_rerror() instead of by the child having STDERR_FILENO refer
5763 to the error log. [Greg Ames, Jeff Trawick]
5765 *) Add '-D' argument processing for run time configuration defines.
5768 *) Organize http_main.c as independent code, such that no code or
5769 global data is exported from it. WIN32 will dynamically link it
5770 to the server core, so this will prevent mutual dependency.
5773 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
5774 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
5777 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
5778 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
5780 *) Add mod_charset_lite for configuring character set translation.
5783 *) Add '-n' option to htpasswd to make it print its user:pw record
5784 on stdout rather than having to frob a text file. [Ken Coar]
5786 *) Fix saferead. Basically, we flush the output buffer if a read on the
5790 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
5791 a conversion is single-byte only. [Jeff Trawick]
5793 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
5794 the BeOS 5.0 documentation says that shutdown doesn't work yet.
5797 *) Fix some minor errors where pid was being manipulated as an int
5798 instead of the portable pid_t. [Roy Fielding]
5800 *) Fix some error log prints that were printing the pointer to a
5801 structure rather than the pid within the structure.
5802 [Jeff Trawick, Roy Fielding]
5804 *) ab: Fix a command-line processing bug; track bad headers in
5805 err_response; support reading headers up to 2K.
5806 [Ask Bjoern Hansen <ask valueclick.com>]
5808 *) Fix ap_resolve_env() so that it handles new function added in a prior
5809 alpha (see "Added the capability to do ${ENVVAR} constructs in the
5810 config file.") as well as the constructs used by mod_rewrite.
5811 [Paul Reder <rederpj raleigh.ibm.com>]
5813 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
5815 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
5816 APR to perform translation, instead of accessing the hard-coded tables
5817 in 1.3's ebcdic.c. [Jeff Trawick]
5819 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
5822 *) Add the ability to hook into the config file reading phase. Basically
5823 if a directive is specified EXEC_ON_READ, then when that directive is
5824 read from the config file, the assocaited function is executed. This
5825 should only be used for those directives that must muck with HOW the
5826 server INTERPRETS the config. This should not be used for directives
5827 that re-order or replace items in the config tree. Those changes should
5828 be made in the pre-config step.
5831 *) Add mod_example to the build system.
5834 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
5835 byte character sets. [Jeff Trawick]
5837 *) Pick up various EBCDIC fixes from 1.3 (from Martin
5838 Kraemer and Oliver Reh originally according to the change log).
5841 *) Fix a couple of problems in RFC1413 support (controlled by the
5842 IdentityCheck directive). Apache did not build the request string
5843 properly and more importantly Apache would loop forever if the
5844 would-be ident server dropped the connection before sending a
5845 properly terminated response. [Jeff Trawick]
5847 *) apxs works in 2.0.
5850 *) Reliable piped logs work in 2.0.
5853 *) Introduce a hash table implementation into APR to be used for
5854 replacing tables and other random data structures in Apache.
5857 *) Add some more error reporting to htpasswd in the case of problems
5858 generating or accessing the temporary file. Also, pass in a
5859 buffer if the implementation knows how to use it (i.e., if L_tmpnam
5860 is defined). [Ken Coar]
5862 *) Configure creates config.nice now containing your configure
5863 options. Syntax: ./config.nice [--more-options]
5866 *) Fix various return code problems in APR on Win32. For most of
5867 these, APR was returning APR_EEXIST instead of GetLastError()/
5868 WSAGetLastError(). [Jeff Trawick]
5870 *) Make piped logs work again in version 2.0
5873 *) Add VPATH support to UNIX build system of Apache and APR.
5876 *) Fix ap_tokenize_to_argv to respect the const arguments that are
5880 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
5881 Patch submitted to author.
5884 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
5885 /sbin in PATH on FreeBSD (all submitted to rse previously)
5888 *) Fix building Pthread-based MPMs on OpenBSD
5889 [Sascha Schumann] PR#26
5891 *) Fix ap_readdir() problem on systems where d_name[] field in
5892 struct dirent is declared with only one byte. (This problem only
5893 affected multithreaded builds.) This caused a segfault during
5894 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
5895 least). [Jeff Trawick]
5897 *) Fix some make-portability problems on at least Tru64, Irix
5899 [Sascha Schumann] PR#18, PR#39
5901 *) Add ap_sigwait() to support old-style sigwait() on systems
5902 like OS/390 and UnixWare.
5905 *) Add POSIX-thread flags for more platforms.
5908 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
5909 (on Unix, at least) to handle resolver errors. Fix a bug in
5910 the definition of APR_ENOMEM so that ap_strerror() can spit
5911 out the correct error message for it.
5914 Changes with Apache 2.0a3
5916 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
5919 *) API: *HOOK* macros now have an AP_ prefix
5922 *) Win32: Eliminate redundant calls to initialize winsock.
5923 [Tim Costello <timcostello ozemail.com.au>]
5925 *) Fix bugs initializing ungetchar for pipes.
5926 [Chia-liang Kao <clkao CirX.ORG>]
5928 *) The ab program in the src/support directory is now portable using
5932 *) Support directory is being compiled when the server is built
5935 *) The configure option --with-program-name has been added to allow
5936 developers to rename the executable at configure time. This also
5937 changes the name of the config files to match the executable's name.
5940 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
5941 containing version numbers. [Martin Pool]
5943 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
5944 Unix; access_log and error_log now created with these perms; non-
5945 Unix is unaffected [Jeff Trawick]
5947 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
5948 Replaced more magic numbers with MD5_DIGESTSIZE.
5949 [William Rowe, Roy Fielding]
5951 *) Win32: Get mod_auth_digest compiling and added to the Windows
5952 build environment. Not tested and I'd be suprised if it
5953 actually works. [Bill Stoddard]
5955 *) Revamp the Win32 make environment. Makefiles have been removed and
5956 Apache.dsw created to bring together all the pieces. Create new file
5957 os/win32/BaseAddr.ref to define module base addresses (to prevent
5958 dll relocation at start-up).
5959 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
5961 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
5962 of the \015, \012, and \015\012 constants with macros.
5965 *) Add ap_xlate_open() et al for translation of text between different
5966 character sets. The initial implementation requires iconv().
5969 *) More FAQs and answers from comp.infosystems.www.servers.unix.
5970 [Joshua Slive <slive finance.commerce.ubc.ca>]
5972 *) CGI output is being timed out now.
5975 *) Fix the problem with dieing quietly. dupfile now takes a pool which
5976 is used by the new apr file. There is no reason to create a new file
5977 with the same lifetime as the original file.
5980 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
5981 module base addresses. This will help shooting seg faults
5982 in the field. [William Rowe <wrowe lnd.com>]
5984 *) Update Apache on Windows documentation. Add new document
5985 describing how to compile Apache on Windows.
5986 [William Rowe <wrowe lnd.com>]
5988 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
5989 microseconds instead of seconds. Some storage leaks and other
5990 minor bugs in related code were fixed. [Jeff Trawick]
5992 *) Win32: First cut at getting mod_isapi working under 2.0
5993 [William Rowe <wrowe lnd.com>]
5995 *) First stab at getting mod_auth_digest working under 2.0
5996 quick change summary:
5997 - moved the random byte generation (ap_generate_random_bytes) into APR
5998 - now uses ap_time_t
5999 - compiles and runs on linux
6001 [Brian Martin <bmartin penguincomputing.com>]
6003 *) Win32: Move the space stripping of physical service names
6004 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
6005 unresolved symbol. Add dependency checking to the
6006 CreateService call to ensure TCPIP and AFP (winsock) is started
6008 [William Rowe <wrowe lnd.com>]
6010 *) Win32: Add code to perform latebinding on functions that may
6011 not exist on all levels of Windows where Apache runs. This
6012 is needed to allow Apache to start-up on Win95/98. All calls
6013 to non portable functions should be protected with
6014 ap_oslevel checks to prevent runtime segfaults.
6015 [William Rowe <wrowe lnd.com>]
6017 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
6019 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
6021 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
6022 This addresses PR 1623. Still need to address timing out runaway
6023 CGI scripts. [Bill Stoddard]
6025 *) Win32: Make ap_stat Windows 95/98 friendly
6026 [William Rowe <wrowe lnd.com>]
6028 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
6029 always fail. Need to initialise the dwOSVersionInfoSize member of the
6030 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
6033 The patch also enhances ap_get_oslevel (and the associated enum) to
6034 handle selected service packs for NT4, and adds recognition for
6035 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
6036 we can use ReadFileScatter and WriteFileGather in readwrite.c.
6037 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
6039 *) Get mod_rewrite building and running, and mod_status building for Win NT
6040 [Allan Edwards <ake raleigh.ibm.com>]
6042 *) Patch to port mod_auth_db to the 2.0 api and also to support
6043 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
6044 2.7.7. It should work with version 1 as well but I haven't tested it.
6045 [Brian Martin <bmartin penguincomputing.com>]
6047 *) Get APR DSO code working under Windows. Includes cross platform
6049 [<Tim.Costello BTFinancialgroup.com>]
6051 *) Fix some of the Windows APR time functions.
6054 *) FAQ changes related to tidying up historical documents on the web site.
6055 [Joshua Slive <slive finance.commerce.ubc.ca>]
6057 *) Move Windows DSO code into APR.
6060 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
6061 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
6062 at build time. At this point, the server will not compile on Windows because
6063 of the recent DSO commits. Fixing those next.
6064 [Bill Rowe & Bill Stoddard]
6066 *) Added error checking for file I/O APR routines.
6067 [Jon Travis <jtravis covalent.net>]
6069 *) APR: Don't use the values of resolver error codes for the
6070 corresponding APR error codes. On Unix and Win32, return the
6071 proper APR error code after a resolver error. [Jeff Trawick]
6073 Changes with Apache 2.0a2
6075 *) Renamed the executable back to httpd on all platforms other
6079 *) Allow BeOS to survive restarts, log properly and a few
6080 small things it had problems with due to the way it setup
6081 users and groups. [David Reid]
6083 *) Get mod_rewrite working with APR locks
6084 [Paul Reder <rederpj raleigh.ibm.com>]
6086 *) Actually remove the sempahore when the lock cleanup routine
6087 is called on BeOS. [David Reid]
6089 *) Clear hook registrations between reads of the config file.
6090 When DSOs are unloaded and re-loaded the old hook pointers may
6091 no longer be valid. This fix eliminates potential segfaults.
6092 [Allan Edwards <ake raleigh.ibm.com>]
6094 *) Fix a problem with Sigfunc not being defined or bypassed
6095 if sigaction() wasn't found. [Jim Jagielski]
6097 *) Fix the locking mechanism on BSD variants. They now use fcntl
6098 locks. This allows the server to start and serve pages.
6101 *) First cut at getting the Win32 installer to work
6102 [William Rowe <wrowe lnd.com>]
6104 *) Get htpasswd compiling under Windows
6105 [William Rowe <wrowe lnd.com>]
6107 *) Change the log message for a bind() failure to show the
6108 interface and port number. [Jeff Trawick]
6110 *) Import the documentation from 1.3.12 and bring parts of it
6111 up-to-date with respect to the changes that have occurred
6115 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
6116 now logged correctly on BeOS.
6119 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
6120 Makefile.win includes the same user interface as the old
6122 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
6124 *) Win32 exec now uses COMSPEC environment string for command
6125 shell path resolution.
6126 [William Rowe <wrowe lnd.com>] PR#3715
6128 *) Win32: ap_connect() was not returning correct error condition
6130 [Allen Prescott <allen clanprescott.com>]
6132 *) Win32: ap_open() was broken on Win9x because an NT-specific
6133 flag was passed to CreateFile. ap_puts() added an unnecessary
6135 [Jeff Trawick <trawick us.ibm.com>]
6137 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
6138 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
6139 confusing ee/et name and made all extensions language/dialect
6140 rather than country reflecting. Changed example files to
6141 explicit reflect the ISO charset and added a few common
6142 ones to the example config [dirkx]
6144 *) Extend external module capability. To use this, you call
6145 configure with --with-module=path/to/mod1,path/to/mod2,etc.
6148 *) Backported the various "default charset" fixes from 1.3.12,
6149 including the AddDefaultCharset directive. [Jim Jagielski]
6151 *) Added the capability to do ${ENVVAR} constructs in the
6152 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
6153 it does this on a line by line basis; i.e. if the envvar
6154 expands to something with spaces you have to protect it
6155 by adding quotes around it (Unless of course you expect it
6156 to contains more than one argument. Alternatively you
6157 can compile it on a per token basis; which is what people
6158 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
6159 hampers fancier hacks.
6160 [Dirk-Willem van Gulik]
6162 *) Changed the 'ErrorDocument' syntax in that it NO longer
6163 supports the asymetric
6165 ErrorDocument 301 "Some message
6167 Note the opening " quote, without a closing quote. It now
6168 has either the following syntaxes
6170 ErrorDocument XXX /local/uri
6171 ErrorDocument XXX http://valid/url
6172 ErrorDocument XXX "Some Message"
6174 The recognition heuristic is: if it has a space it
6175 is a message. If it has no spaces and starts with a /
6176 or is a valid URL then treat it that way. Otherwise it
6177 is assumed to be a message.
6179 This breaks backward compatibility but makes live a hell
6180 of a lot easier for GUI's and config file parsers.
6181 [Dirk-Willem van Gulik]
6183 *) Changed 'CacheNegotiatedDocs' from its present/not-present
6184 syntax into a 'on' or 'off' syntax. As it currently is the
6185 only non nesting token which uses NO_ARGS and thus is an
6186 absolute pain for any config interface automation. This
6187 breaks backward compatibility. [Dirk-Willem van Gulik]
6189 *) Add ability to add external modules to the build process. This is
6190 done with --with-module=/path/to/module. Modules can only be added
6191 as static modules at this point.
6194 Changes with Apache 2.0a1
6196 *) Fix FreeBSD 3.3 core dump.
6197 Basically, ap_initialize() needs to get called before
6198 create_process(), since create_process() passes op_on structure
6199 to semop() to get a lock, but op_on isn't initialized until
6200 ap_initialize() calls setup_lock(). Here is a slight
6201 rearrangement to main() which calls ap_initialize() earlier...
6202 [Jeff Trawick <trawick us.ibm.com>]
6204 *) Enable Apache to use sendfile/TransmitFile API
6205 [Bill Stoddard, David Reid, Paul Reder]
6207 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
6211 *) Make file I/O and network I/O writev/sendv APIs consistent.
6212 Eliminate use of ap_iovec_t and use Posix struct iovec.
6213 Use seperate variable on ap_writev to set the number of iovecs
6214 passed in and number of bytes written.
6217 *) Adapt file iol to use APR functions. Replaced ap_open_file()
6218 with ap_create_file_iol(). ap_create_file_iol() requires that
6219 the file be opened prior to the call using ap_open().
6222 *) Port mod_include and mod_cgi to 2.0
6223 [Paul Reder, Bill Stoddard]
6225 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
6226 bytes_read/bytes_written is always valid (never -1). Plus
6227 some fixes to buff.c to correct problems introduced by the
6228 errno => ap_status_t changes a while back. Plus a fix to
6229 chunked encoding introduced right at the beginning of 2.0.
6232 *) Revamped UNIX build system to use autoconf and libtool.
6233 [Manoj Kasichainula, Sascha Schumann]
6235 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
6237 *) SECURITY: More rigorous checking of Host: headers to fix security
6238 problems with mass name-based virtual hosting (whether using mod_rewrite
6239 or mod_vhost_alias).
6240 [Ben Hyde, Tony Finch]
6242 *) Add back support for UseCanonicalName in <Directory> containers.
6243 [Manoj Kasichainula]
6245 *) Added APLOG_STARTUP log type. This allows us to write an error
6246 message without any of the date and time information. As a part
6247 of this change, I also removed all of the calls to fprintf(stderr
6248 and replaced them with calls to ap_log_error using APLOG_STARTUP
6249 writing to stderr is no longer portable, because we don't direct
6250 stderr to the error log on all platforms.
6253 *) Convert error logging functions to take errno as an argument.
6254 This makes our error logs more portable, because some Windows API's
6255 don't set errno. This change allows us to still output a valid
6256 message on all of our platforms.
6259 *) mod_mime_magic runs in 2.0-dev now.
6260 [Paul Reder <rederpj raleigh.ibm.com>]
6262 *) sendfile has been added to APR.
6263 [John Zedlewski <zedlwski Princeton.EDU>]
6265 *) buff.c has been converted to no longer use errno.
6266 [Manoj Kasichainula]
6268 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
6269 interface adaption to APR functions did it. [Martin Kraemer]
6271 *) Support DSOs properly on 32-bit HP-UX 11.0
6272 [Dilip Khandekar <dilip cup.hp.com>]
6274 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
6275 [Ralf S. Engelschall]
6277 *) Cleaned APR build environment integration and bootstrap APR
6278 automatically for developers from src/Configure.
6279 [Ralf S. Engelschall]
6281 *) Fixed building of src/support/htpasswd.c
6282 [Ralf S. Engelschall]
6284 *) When generating the Location: header, mod_speling forgot
6285 to escape the spelling-fixed uri. (Forw-Port from 1.3)
6288 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
6290 *) Change all pools to APR contexts. This is the first step to
6291 incorporating APR into Apache. [Ryan Bloom]
6293 *) Move "handler not found" warning message to below the check
6294 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
6295 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
6297 *) Support line-continuation feature in config.option file and
6298 allow the loading of multiple option sections at once via
6299 ``--with-option=<section1>,<section2>,...''
6300 [Ralf S. Engelschall]
6302 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
6304 Changes with Apache MPM
6306 *) Use asynchronous AcceptEx() and a completion port to accept and
6307 dispatch connections to threads in Windows NT/2000.
6310 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
6313 *) Implement the APACI --with-option facility
6314 (per default used the config.option file).
6315 [Ralf S. Engelschall]
6317 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
6319 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
6320 Replace pre_connection module call with a register_hook call and
6321 implement pre_connection as a hook. The intent is that these hooks will
6322 be extended to allow Apache to be multi-protocol, and also to allow the
6323 calling order to be specified on a per-hook/per-module basis.
6326 *) Implement mpm_* methods as "modules". Each method gets its own
6327 subdir in src/modules (eg: src/modules/prefork). Selection
6328 of method uses Rule MPM_METHOD. [Jim Jagielski]
6330 *) Port the hybrid server from the apache-apr repository as
6331 mpm_mpmt_pthread. [Manoj Kasichainula]
6333 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
6334 amongst the unix MPMs.
6336 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
6337 signal handling for the new world order. [Dean Gaudet]
6339 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
6340 of alloc.c for now. [Dean Gaudet]
6342 *) Handle partial large writes correctly. [Ben Laurie]
6344 *) Eliminate conn_rec's pointer to server. All it knows is the base server
6345 based on IP/port. [Ben Laurie]
6347 *) Port a bunch of modules to the new module structure.
6348 ["Michael H. Voase" <mvoase midcoast.com.au>]
6350 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
6352 *) Basic restructuring to introduce the MPM concept; includes various
6353 changes to the module API... better described by
6354 docs/initial_blurb.txt. [Dean Gaudet]
6356 Changes with Apache pthreads
6358 *) New buff option added: BO_TIMEOUT. It describes the timeout for
6359 buff operations (generally over a network).
6360 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
6362 *) Created http_accept abstraction. Added 4 new functions (not exported):
6363 init_accept(), begin_accepting_requests(), get_request(),
6364 stop_accepting_requests() [Bill Stoddard]
6366 *) Fix to ap_rprintf call that allows mod_info to work properly.
6367 [James Morris <jmorris intercode.com.au>]
6369 *) user and ap_auth_type fields were moved from connection_rec to
6370 request_rec. [Ryan Bloom]
6372 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
6373 needed in a threaded server.
6375 *) Initial pthread implementation from from Dean's apache-nspr code.
6376 [Bill Stoddard, Ryan Bloom]
6379 Changes with Apache 1.3.9
6381 *) Remove bogus error message when a redirect doesn't set Location.
6382 Instead, use an empty string to avoid coredump if the error message
6383 was supposed to include a location. [Roy Fielding]
6385 *) Don't allow configure to include mod_auth_digest unless it is
6386 explicitly requested, even if the user asked for all modules.
6389 *) Translate module names to dll names for OS/2 so that they are no more
6390 than 8 characters long and have an extension of "dll" instead of "so".
6393 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
6394 Fix test-compile check to check for randbyte instead of trand32.
6395 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
6396 and tweak to make Amaya happier. [Ronald Tschalär]
6398 *) Ensure that the installed expat include files are world readable,
6399 just like the other header files. [Martin Kraemer]
6401 *) Fixed generated AddModule adjustments in APACI's `configure' script
6402 in order to allow (new) modules like mod_vhost_alias to be handled
6403 correctly (which was touched by the adjustments for mod_alias).
6404 [Ralf S. Engelschall]
6406 *) For binary builds, add -R flag to apachectl to work around the lack of
6407 an absolute path to the ./libexec directory where the libhttp.ep file
6408 is needed for SHARED_CORE architectures. [Randy Terbush]
6410 *) WIN32: Create the CGI script process as DETACHED. This may solve the
6411 problem observed by some Win95/98 users where they get CGI script
6412 output sent to the console. [Bill Stoddard]
6414 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
6415 routines are now called ap_base64* and are 'plain' (i.e., no
6416 pool access or anything clever). Inside util.c the routines acting
6417 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
6418 The oddly named ap_uuencode(), ap_uudecode() are kept around for
6419 now but deprecated. [dirkx]
6421 *) Clean up the base64 and SHA1 additions and make sure they are
6422 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
6423 files. [Roy Fielding]
6425 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
6426 checking. Allow compiling on VS 6.0. [Randy Terbush]
6428 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
6430 *) Use TestCompile to search for the truerand library (rather than blindly
6431 assuming its existence). If it is not found, complain (but do not
6432 exit - yet). [Martin Kraemer]
6434 *) We forgot to add the new exported function names to
6435 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
6437 *) Add description of -T command-line option to usage().
6438 [Ralf S. Engelschall]
6440 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
6441 searched only AFTER libap has been searched, because libap needs
6442 some symbols from libos. [Martin Kraemer]
6444 *) Fix conflict with original mod_digest related to the symbol of the
6445 module dispatch list (which has to be unique for DSO and follow the
6446 usual conventions for the installation procedure).
6447 [Ralf S. Engelschall]
6449 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6450 for other platforms as well. [Martin Kraemer]
6452 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6453 types by AP_LONG and replace reference to renamed variable 'ubuf'
6454 by 'buffer'. [Martin Kraemer]
6456 Changes with Apache 1.3.8 [not released]
6458 *) Flush the output buffer immediately after sending an error or redirect
6459 response, since the result may be needed by the client to abort a
6460 long data transfer or restart a series of pipelined requests.
6461 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
6463 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6464 [Ian Turner <iant sequent.com>] PR#4735
6466 *) Local struct mmap in http_core.c conflicted with system structure
6467 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6469 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6470 [Ronald Tschalär <ronald innovation.ch>]
6472 *) Fix a memory leak where the module counts were getting messed
6473 up across restarts. [David Harris <dharris drh.net>]
6475 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6476 properly in mod_access.
6477 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
6479 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6480 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
6482 *) PORT: Support for compaq/tandem/com.
6483 [Michael Ottati <michael.ottati compaq.com>, dirkx]
6485 *) Added SHA1 password encryption support to easy migration from
6486 Netscape servers. See support/SHA1 for more information.
6487 Caused the separation of ap_md5.c into md5, sha1 and a general
6488 ap_checkpass.c with just a validate_passwd routine. Added a
6489 couple of flags to support/htpasswd. Some reuse of the to64()
6490 function; hence renamed to ap_to64().
6491 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
6493 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6494 with ASCII/EBCDIC conversions in "ident" query.
6495 [David McCreedy <McCreedy us.ibm.com>]
6497 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6498 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6499 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6501 *) Fix SIGSEGV on some systems because the Vary fix below included
6502 a call to table_do with a variable argument list that was not
6503 NULL terminated. Replaced with better implementation. [Roy Fielding]
6505 Changes with Apache 1.3.7 [not released]
6507 *) The "Vary" response header field is now sanitised right before
6508 the header is sent back to the client. Multiple "Vary" fields
6509 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6510 "Vary: host, negotiate, host, accept-language") are reduced to
6511 single instances. This is a better solution than the force-no-vary
6512 one (which is still valid for clients that can't cope with Vary
6513 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6515 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
6517 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6518 least on Linux and FreeBSD for now.
6521 *) Win32: More apache -k restart work. Restarts are now honored
6522 immediately and connections in the listen queue are -not- lost.
6523 This is made possible by the use of the WSADuplicateSocket()
6524 call. The listeners are opened in the parent, duplicated, then
6525 the duplicates are passed to the child. The original listen sockets
6526 are not closed by the parent across a restart, thus the listen queue
6528 [Bill Stoddard <stoddard raleigh.ibm.com>]
6530 *) Fix handling of case when a client has sent "Expect: 100-continue"
6531 and we are going to respond with an error, but get stuck waiting to
6532 discard the body in the pointless hope of preserving the connection.
6533 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
6535 *) Fix 'configure' to work correctly with SysV-based versions of
6536 'tr' (consistent with Configure's use as well). [Jim Jagielski]
6538 *) apxs: Add "-S var=val" option which allows for override of CFG_*
6539 built-in values. Add "-e" option which works like -i but doesn't
6540 install the DSO; useful for editing httpd.conf with apxs. Fix
6541 editing code so that multiple invocations of apxs -a will not
6542 create duplicate LoadModule/AddModule entries; apxs can now be
6543 used to re- enable/disable a module. [Wilfredo Sanchez]
6545 *) Win32: Update the server to use Winsock 2. Specifically, link with
6546 ws2_32.lib rather than wsock32.lib. This gives us access to
6547 WSADuplcateSocket() in addition to some other enhanced comm APIs.
6548 Win 95 users may need to update their TCP/IP stack to pick up
6549 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
6550 [Bill Stoddard <stoddard raleigh.ibm.com>]
6552 *) Win32: Redirect CGI script stderr (script debug info) into the
6553 error.log when CGI scripts fail. This makes Apache on Win32
6554 behave more like Unix.
6555 [Bill Stoddard <stoddard raleigh.ibm.com>]
6557 *) Fixed `httpd' usage display: -D was missing.
6558 [Ralf S. Engelschall] PR#4614
6560 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
6561 [Ralf S. Engelschall] PR#4561, PR#4562
6563 *) OS/2: Fix problem with accept lock semaphores where server would die with
6564 "OS2SEM: Error 105 getting accept lock. Exiting!"
6565 [Brian Havard] PR#4505
6567 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
6568 [Randy Terbush <randy covalent.net>]
6570 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
6571 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
6573 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
6574 command potentially _is_ GCC. [Ralf S. Engelschall]
6576 *) Fix apxs build issues on AIX
6577 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
6579 *) DocumentRoot Checking: Under previous versions, when Apache
6580 first started up, it used to do a stat of each DocumentRoot to
6581 see if it existed and was a directory. If not, then an error
6582 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
6583 does not exist, you will get error messages in error_log. If
6584 the '-t' command line option is used (to check the configuration)
6585 the check of DocumentRoot IS performed. An additional command
6586 line option, '-T', has been added if you want to avoid the
6587 DocumentRoot check even when checking the configuration.
6590 *) Win32: The query switch "apache -S" didn't exit after showing the
6591 vhost settings. That was inconsistent with the other query functions.
6592 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
6594 *) Win32: Changed behaviour of apache -k restart.
6595 Previously, the server would drain all connections in the stack's
6596 listen queue before honoring the restart. On a busy server, this
6597 could take hours. Now, a restart is honored almost immediately.
6598 All connections in Apache's queues are handled but connections in
6599 the stack's listen queue are discarded. Restart triggered by
6600 MaxRequestPerChild is unchanged.
6601 [Bill Stoddard <stoddard raleigh.ibm.com>]
6603 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
6604 the accept loop. Good for a 5% performance boost. Cleaned up
6605 parent/child process management code.
6606 [Bill Stoddard <stoddard raleigh.ibm.com>]
6608 *) Added ceiling on file size for memory mapped files.
6609 [John Giannandrea <jg meer.net>] PR#4122
6611 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
6612 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
6613 [Henri Gomez <gomez slib.fr>, Ralf S. Engelschall]
6615 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
6616 use this at least for Expat. [Ralf S. Engelschall]
6618 *) Allow .module files to specify libraries with Lib:.
6621 *) Allow SetEnvIf[NoCase] to test environment variables as well
6622 as header fields and request attributes. [Ken Coar]
6624 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
6625 content-types are "text/html;parameters". PR#4524 [Ken Coar]
6627 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
6628 never accepted into any standard, and it opens up certain DoS
6629 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
6631 *) TestCompile updated. We can now run programs and output the
6632 results during the Configure process. [ Jim Jagielski]
6634 *) The source is now quad (long long) aware as needed. Specifically,
6635 the Configure process determines the correct size of off_t and
6636 *void. When the OS/platform/compiler supports quads, ap_snprintf()
6637 provides for the 'q' format qualifier (if quads are not available,
6638 'q' is silently "demoted" to long). [Jim Jagielski]
6640 *) When the username or password fed to htpasswd is too long, include the
6641 size limit in the error message. Also report illegal characters
6642 (currently only ':') in the username. Add the size restrictions
6643 to the man page. [Ken Coar]
6645 *) Fixed the configure --without-support option so it doesn't result in
6646 an infinite loop. [Marc Slemko]
6648 *) Piped error logs could cause a segfault if an error occured
6649 during configuration after a restart.
6650 [Aidan Cully <aidan panix.com>] PR#4456
6652 *) If a "Location" field was stored in r->err_headers_out rather
6653 than r->headers_out, redirect processing wouldn't find it and
6654 the server would core dump on ap_escape_html(NULL). Check both
6655 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
6656 if Location isn't set. [Doug MacEachern, Ken Coar]
6658 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
6659 of the Expat 1.0.2 distribution. [Greg Stein]
6661 *) Replace regexec() calls with calls to a new API stub function
6662 ap_regexec(). This solves problems with DSO modules which use the regex
6663 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]
6665 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
6666 environment variables can be set according to the protocol version
6667 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
6669 *) Add DSO support for OpenStep (Mach 4.2) platform.
6670 [Ralf S. Engelschall, Rex Dieter <rdieter math.unl.edu>] PR#3997
6672 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
6673 [Jan Gallo <gallo pvt.sk>] PR#3690, PR#4373
6675 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
6676 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
6678 *) Better DSO flags recognition on NetBSD platforms using ELF.
6679 [Todd Vierling <tv pobox.com>] PR#4310
6681 *) Always log months in english format for %t in mod_log_config.
6682 [Petr Lampa <lampa fee.vutbr.cz>] PR#4366, 679
6684 *) Support for server-parsed and multiview-determined ReadmeName and
6685 HeaderName files in mod_autoindex. Removed the restriction on
6686 "/"s in ReadmeName and HeaderName directives since the *sub_req*
6687 routines will deal with the access issues. (It's now possible to
6688 have {site|group|project|customer|...} wide readmes and headers.)
6689 [Raymond S Brand <rsbx rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
6692 *) When stat() fails, don't assume anything about the contents of
6693 the struct stat. [Ed Korthof <ed bitmechanic.com>]
6695 *) It's OK for a semop to return EINTR, just loop around and try
6696 again. [Dean Gaudet]
6698 *) Fix configuration engine re-entrant hangups, which solve a
6699 handful of problems seen with mod_perl <Perl> configuration sections
6700 [Salvador Ortiz Garcia <sog msg.com.mx>]
6702 *) Mac OS and Mac OS X Server now use the appropriate custom layout
6703 by default when building with APACI; allow for platform-specific
6704 variable defaults in configure. [Wilfredo Sanchez]
6706 *) Do setgid() before initgroups() in http_main; some platforms
6707 zap the grouplist when setgid() is called. This was fixed in
6708 suexec earlier, but the main httpd code missed the change.
6709 [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2579
6711 *) Add recognition of .tgz as a gzipped tarchive.
6712 [Bertrand de Singly <bertrand.de-singly polytechnique.fr>] PR#2364
6714 *) mod_include's fsize/flastmod should allow only relative paths, just
6715 like "include file". [Jaroslav Benkovsky <benkovsk pha.pvt.cz>]
6717 *) OS/2: Add support for building loadable modules using DLLs.
6720 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
6723 *) Fix minor but annoying bug with the test for Configuration.tmpl
6724 being newer than Configuration so that it is less likely to fail
6725 when using APACI and shadow sources. [Wilfredo Sanchez]
6727 *) PORT: Add initial support for Mac OS (versions 10.0 and
6728 greater). Use Mac OS X Server layout for now. Clean up dyld code
6729 in unix/os.c, and don't install the dyld error handlers, which
6730 are no longer needed in Mac OS. [Wilfredo Sanchez]
6732 *) Rename Rhapsody layout to "Mac OS X Server". Change install
6733 locations to appropriate ones for user-built (as opposed to
6734 system) installs. [Wilfredo Sanchez]
6736 *) Modify mod_autoindex's handling of AddDescription so that the
6737 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
6739 *) Add functionality to the install-bindist.sh script created by
6740 binbuild.sh to use tar when copying distribution files to the
6741 serverroot. This allows upgrading an existing installation
6742 without nesting the new distribution in the old.
6744 install-bindist.sh now detects the local perl5 path to install
6745 apxs and dbmmanage with proper path to perl interpreter.
6747 Add an install-binsupport target which copies the source files
6748 for apxs and dbmmanage to bindist to allow these scripts to
6749 be properly installed relative to the destination serverroot.
6750 [Randy Terbush, Covalent Technologies, <randy covalent.net>]
6752 *) Fix intermittent SEGV in ap_proxy_cache_error() in

6764 *) Force the LANG envariable to the known state of "C" so that we
6765 have assurance about how string manipulators (e.g., tr) will

6772 clients that choke on "Vary" fields in the response header.
6773 [Ken Coar, Dmitry Khrustalev <dima zippy.machaon.ru>] PR#4118
6775 *) Fixed a bug in mod_dir that causes a child process will infinitely
6776 recurse when it attemps to handle a request for a directory wnd the
6777 value of the DirectoryIndex directive is a single dot. Also likely
6778 to happen for anyother values of DirectoryIndex that will map back
6779 to the same directory. The handler now only considers regular files
6780 as being index candidates. No PR#s found.

6789 *) Add "opt" (SysV-style) layout to config.layout. [Raymond S Brand
6792 *) Add APACI --without-execstrip option which can be used to disable the
6793 stripping of executables on installation. This is very important for DSO
6794 and debugging situations. [Ralf S. Engelschall]
6796 *) Add support for OS/2 (case insenstive filesystem, .exe suffix, etc)
6797 to APACI files and related scripts.

6860 [Peter 'Luna' Altberg <peter altberg.nu>, Ronald Tschalär]
6862 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
6865 *) Correct an apparent typo: on the Windows and MPE platforms, the
6866 htpasswd utility was limiting passwords to only 8 characters.
6869 *) EBCDIC platforms: David submitted patches for two bugs in the
6870 MD5 digest port for EBCDIC machines:
6871 a) the htdigest utility overwrote the old contents of the digest file
6872 b) the Content-MD5 header value (ContentDigest directive) was wrong
6873 when the returned file was not converted from EBCDIC, but was a
6874 binary (e.g., image file) in the first place.
6875 [David McCreedy <mccreedy us.ibm.com>]
6877 *) support/htpasswd now permits the password to be specified on the
6878 command line with the '-b' switch. This is useful when passwords
6879 need to be maintained by scripts -- particularly in the Win32
6880 environment. [Ken Coar]
6882 *) Win32: Win32 multiple services patch. Added capability to install and
6883 run multiple copies of apache as individual services.
6886 apache -n apache1 -i -f c:/httpd.conf
6887 Installs apache as service 'apache1' and associates c:/httpd.conf
6890 Starts apache1 service.
6892 Stops apache1 service
6895 apache -n apache2 -i
6896 Installs apache as service 'apache2'. httpd.conf is located under
6897 the default server root (/apache/conf/httpd.conf).
6899 Starts apache2 service.
6902 apache -n apache3 -i -d c:/program files/apache
6903 Install apache as service 'apache3' and sets server root to
6904 c:/program files/apache.
6907 apache -n apache2 -k restart
6908 Restart apache2 service
6910 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
6912 *) Correct the signed/unsigned character handling for the MD5 routines;
6913 mismatches were causing compilation problems with gcc -pedantic and
6914 in the TPF cross-compilation. [Ken Coar]
6916 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
6917 a roughly 5 fold speed up. [Brian Havard]
6919 *) proxy ftp: instead of using the hardwired string "text/plain" as
6920 a fallback type for files served by the ftp proxy, use the
6921 ap_default_type() function to determine the configured type.
6922 This allows for special configurations like
6923 <Directory proxy:ftp://some.host>
6924 DefaultType gargle/blurb
6926 Additionally, add the Content-Encoding: header to FTP proxy replies
6927 when the encoding is defined (by the AddEncoding directive).
6928 Because it was missing, it was almost impossible to browse compressed
6929 files using the FTP proxy (works now perfectly in Communicator).
6930 The ftp proxy now also returns the Date: and Server: header lines (if not
6931 much else... This code is "somewhat" broken) like normal requests do.
6934 *) Be more smart in APACI's configure script when determining the UID/GID
6935 for User/Group directives and use the determined UID/GID to initialize
6936 the permissions on the proxycachedir.
6937 [Dirk-Willem van Gulik, Ralf S. Engelschall]
6939 *) Changed the forking-prior-to-cleanup in the proxy module to first
6940 check wether it actually needs to collect garbage. This reduces
6941 the number of fork()s from one/request to just the odd one an hour.
6942 [Dirk-Willem van Gulik]
6944 *) Added proxy, auth and header support to src/support/ab.c. Added a

6951 *) Add support for DSO module compilation on BSD/OS 3.x.
6952 [Randy Terbush, Covalent Technologies]
6954 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
6955 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
6956 option) were substituted with $(TARGET).conf, etc. Same for other strings
6957 with dots where the dot wasn't matched as plain text.

6965 Changes with Apache 1.3.6
6967 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
6969 Changes with Apache 1.3.5 [not released]
6971 *) M_INVALID needed a value within the scope of METHODS so that unknown
6972 methods can be access controlled. [Roy Fielding] PR#3821
6974 *) Added PassAllEnv; makes server's entire environment available
6975 to CGIs and SSIs executed within directive's scope. [Ken Coar]
6977 *) ap_uuencode() always added two trailing '='s and encoding of
6978 8 bit characters on a machine with signed char may produced
6979 incorrect results. Additionally ap_uuencode() should now
6980 work correctly on EBCDIC platforms.
6981 [Ronald Tschalär <ronald innovation.ch>] PR#3411
6983 *) WIN32: Binary installer now runs the configuration DLL before
6984 the reboot prompt (which is only given if MSVCRT.DLL system
6985 DLL is new or updated). This should avoid the configuration
6986 directory being empty after installation. [Paul Sutton]
6987 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

6990 and stop Apache as a console application and to uninstall
6991 the Apache service on NT. [Paul Sutton] PR#3741
6993 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
6995 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
6996 have been reported with flock() locking (probably related to kernel
6997 version). [Dean Gaudet] PR#2723, 3531
6999 *) Using APACI, the main config file (usually httpd.conf) was
7000 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
7001 <wsanchez apple.com>]
7003 *) PORT: AIX does not require the SHARED_CODE "hack"

7010 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
7011 for 8-bit safeness. [Dean Gaudet]
7013 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
7014 because SPARCs have a small machine-specific maximum size for the Global
7015 Offset Table which is often exceeded when compiling one of the larger
7016 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977
7018 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
7019 DSO/DLL section because it's a directive from mod_status and isn't
7020 available before the DLL of mod_status is loaded.
7021 [Martin POESCHL <mpoeschl gmx.net>] PR#3936
7023 *) SECURITY: Fix a bug in the calculation of the buffer size for the line

7033 [John Tobey <jtobey banta-im.com>] PR#3983
7035 *) Let APACI's configure script correctly complain for unknown --enable-XXX
7036 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
7038 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
7039 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
7040 possible buffer overflows. [Ralf S. Engelschall]
7042 *) Remove no longer used non-API function ap_single_module_init().
7043 [Ralf S. Engelschall]
7045 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
7048 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
7049 to make platform installations easier. [Wilfredo Sanchez]
7051 *) In configure, do not append the target name to the directory path if
7052 the path already contains "apache". [Ralf S. Engelschall]
7054 *) SIGPIPE is now ignored by the server core. The request write routines
7055 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
7056 correctly check for output errors and mark the connection as aborted.
7057 Replaced many direct (unchecked) calls to ap_b* routines with the
7058 analogous ap_r* calls. [Roy Fielding]
7060 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
7061 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
7062 Furthermore map lookups for non-existent keys are now cached as well.
7063 Additionally "txt" maps are now parsed with simple string functions
7064 instead of using ap_pregcomp(). As a side effect a bug that prevented
7065 the usage of keys containing the "," character was fixed.
7066 The changes drastically improve the performance when large rewrite maps
7068 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
7070 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
7071 other than GET, and const'd the definition of method in request_rec.
7074 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
7076 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
7077 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
7079 *) Add %V to mod_log_config, this logs the hostname according to the
7080 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
7081 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
7083 *) Add support for \n and \t to mod_log_config, can be used to produce
7084 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
7086 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
7088 *) Added informative error messages for failed munmap() and fseek() calls
7089 in http_core.c. [John Bley, Roy Fielding]
7091 *) Added some informative error messages for some failed malloc()
7092 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
7094 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
7095 is removed. This allows <Directory proxy:*> directives to work and
7096 prevents invalid requests from killing the process.
7097 [Brian Havard <brianh kheldar.apana.org.au>]
7099 *) Reorganised FAQ document.
7100 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497
7102 *) src/support/: The ApacheBench benchmark program was overhauled by
7103 David N. Welton: you can now have it generate an HTML TABLE, presumably
7104 for integration into other HTML sources. David updated the ab man page
7105 as well and added some missing descriptions. Thanks!
7106 [David N. Welton <davidw prosa.it>]
7108 *) Win32: The filename validity checker now allows filenames containing
7109 characters in the range 0x80 to 0xff (for example accented characters).
7110 [Paul Sutton] PR#3890
7112 *) Added conditional logging based upon environment variables to
7113 mod_log_config. mod_log_referer and mod_log_agent
7114 are now deprecated. [Ken Coar]
7116 *) Allow apache acting as a proxy server to relay the real
7117 reason of a failure to a client rather than the "internal
7118 server error" it does currently. The general exposure mechanism
7119 can be triggered by any module by setting the "verbose-error-to"
7120 note to "*"; this allows more than just proxy errors to be exposed.
7121 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
7123 *) Moved man pages for ab and apachectrl to section 8.
7124 [Wilfredo Sanchez, Roy Fielding]
7126 *) Added -S option to install.sh so that options can be passed to
7127 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
7129 *) Tweak modules Makefile generated by Configure so that it handles
7130 the test case of no modules being selected. [<chaz reliant.com>]
7132 *) Added a <LimitExcept method ...> sectioning directive that allows
7133 the user to assign authentication control to any HTTP method that
7134 is *not* given in the argument list; i.e., the logical negation
7135 of the <Limit> directive. This is particularly useful for controlling
7136 access on methods unknown to the Apache core, but perhaps known by
7137 some module or CGI script. [Roy Fielding, Tony Finch]
7139 *) Prevent apachectl from complaining if the PIDFILE exists but
7140 does not contain a process id, as might occur if the server is
7141 being rapidly restarted. [Wilfredo Sanchez]
7143 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
7145 *) Entity tag comparisons for If-Match and If-None-Match were not being
7146 performed correctly -- weak tags might cause false positives. Also,
7147 strong comparison wasn't properly enforced in all cases.
7148 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
7150 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
7153 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
7154 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
7156 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
7157 to util.c for parsing an HTTP header field value to extract the next
7158 list item, taking into account the possible presence of nested comments,
7159 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
7160 insignificant whitespace and lowercases non-quoted tokens.
7161 [Roy Fielding] PR#2065
7163 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
7164 code different from 500. This allows the proxy to, e.g., return
7165 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
7167 *) Fix ordering of language variants for the case where the traditional
7168 negotiation algorithm is being used with multiple language variants
7169 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
7171 *) Do not round the TCN quality calculation to 5 decimal places,
7172 unlike RFC 2296, because the calculation might need 12 decimal places
7173 to get the right result. [Roy Fielding]
7175 *) Remove unused code to disable transparent negotiation when
7176 negotiating on encoding only, as we now handle encoding too
7177 (though this is nonstandard for TCN), remove charset=ISO-8859-1
7178 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
7179 some debugging statements within mod_negotiation. [Koen Holtman]
7181 *) Fixed a rare memory corruption possibility in mod_dir if the index
7182 file is negotiable and no acceptable variant can be found.
7183 [Dean Gaudet, Roy Fielding, Martin Kraemer]
7185 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
7186 searching the Win32 registry for script interpreters.
7189 *) Win32: The compiled-in default filename for the error log is now
7190 error.log, which matches the default in the distributed httpd.conf.
7193 *) Win32: Any error messages from -i or -u command line options are now
7194 displayed on the console output rather than sent to the error log.
7195 Also the "Running Apache..." message is not output unless Apache is
7196 going to serve requests. [Paul Sutton]
7198 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
7199 and use a private significator ('$apr1$') to mark passwords as
7200 being smashed with our own algorithm. Also abstract the password
7201 checking into a new ap_validate_password() routine. [Ken Coar]
7203 *) Win32: The filename validity checker now allows "COM" but refuses
7204 access to "COM1" through "COM4". This allows filenames such
7205 as "com.name" to be served. [Paul Sutton] PR#3769.
7207 *) BS2000: Adapt to the new ufork() system call interface which will
7208 make subtasking easier on the OSD/POSIX mainframe environment.
7211 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
7212 ap_compat.h. [David White <david persimmon.com>] PR#3725
7214 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
7215 use `.db' instead of `.pag' not only for FreeBSD, but also when
7216 the NDBM library looks like Berkeley-DB based.
7217 [Ralf S. Engelschall] PR#3773
7219 *) Add ability to handle DES or MD5 authentication passwords.
7220 [Ryan Bloom <rbb Raleigh.IBM.Com>]
7222 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
7224 *) SECURITY: Avoid some buffer overflow problems when escaping
7225 quoted strings. (This overflow was on the heap and we believe
7226 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
7228 *) Let src/Configure be aware of CFLAGS options starting with plus
7229 signs as it's the case for the HP/UX compiler.
7230 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
7232 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
7233 and check to see if the tar we wind up with supports '-h'.
7234 [Jim Jagielski] PR#3671
7236 *) A consistent and conservative style for all shell scripts has been
7237 implemented. Basically, all shell string tests use the traditional
7238 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
7239 to protect against bare null variable strings (ie: wrapping both
7240 sides with double quotes and prepending 'x'). 'x' was chosen
7241 because it's more universal and hopefully easier for old shell
7242 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
7245 *) The status module now prints out both the main server generation as
7246 well as the generation of each process. Also, the vhost info is
7247 printed with '?notable'. [Jim Jagielski]
7249 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
7250 and this makes its functions available to things in src/support.
7253 Changes with Apache 1.3.4
7255 *) Renamed macros status_drops_connection to ap_status_drops_connection
7256 and vestigial scan_script_header to ap_scan_script_header_err,
7257 mostly for aesthetic reasons. [Roy Fielding]
7259 *) The query switch "httpd -S" didn't exit after showing the
7260 vhost settings. That was inconsistent with the other query functions.
7263 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
7264 filename to the end of the STANDARD_MODULE_STUFF. Its
7265 presence at the beginning prevented reporting of the filename
7266 for modules compiled before 1 January 1999. [Ken Coar]
7268 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
7269 to detect and prevent access to special DOS device file names.
7270 [Paul Sutton, Ken Parzygnat]
7272 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
7273 and Makefile_win32_debug.txt (debug build) that work on Win95.
7274 Run each of the following from the src directory:
7275 nmake /f Makefile_win32.txt # compiles normal build
7276 nmake /f Makefile_win32.txt install # compiles and installs
7277 nmake /f Makefile_win32.txt clean # removes compiled junk
7278 nmake /f Makefile_win32_debug.txt # compiles debug build
7279 nmake /f Makefile_win32_debug.txt install
7280 nmake /f Makefile_win32_debug.txt clean
7283 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
7284 to build binary distributions. [Lars Eilebrecht]
7286 *) IndexOptions SuppressColumnSorting only turned off making
7287 the column headers anchors; you could still change the display
7288 order by manually adding a '?N=A' or similar query string to the
7289 URL. Now SuppressColumnSorting locks in the sort order so
7290 it can't be overridden this way. [Ken Coar]
7292 *) Added IndexOrderDefault directive to supply a default sort order
7293 for FancyIndexed directory listings. [Ken Coar] PR#1699
7295 *) Change the ap_assert macro to a variant that works on all platforms.
7296 [Richard Prinz <richard.prinz cso.net>] PR#2575
7298 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
7299 search for an underscore on dlsym() (as it's already the case
7300 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
7302 *) Small fix for mod_env.html: The module was documented as to be _not_
7303 compiled into Apache per default, although it _IS_ compiled into
7304 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
7306 *) Instead of fixing a bug in the generation procedure for config.status (a
7307 backslash was missing) we remove the bug together with it's complete
7308 context because the special cases of the past can now no longer occur
7309 because of the recent magic for the --with-layout default.
7310 [Ralf S. Engelschall] PR#3590
7312 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
7313 making sure the src/support/ tools are _forced_ to be build last (they
7314 depend on other libraries).
7315 [Markus Theissinger <markus.theissinger gmx.de>]
7317 *) Fix installation procedure: Now that os-inline.c is actually used (a
7318 recently fixed bug prevented this) we need to also install os-include.c
7319 in addition to os.h into the PREFIX/include/ location or building of
7320 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
7322 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
7323 allow us to distinguish between a garbled DSO (or even a file which isn't
7324 an Apache module DSO at all) and a DSO which doesn't match the current
7325 Apache API. [Ralf S. Engelschall] PR#3152
7327 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
7328 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
7329 match case insensitive (this especially avoids nasty patterns like
7330 `[tT][eE][sS][tT]'). Second two additional internal map functions
7331 `escape' and `unescape' were added which can be used to escape/unescape
7332 to/from hex-encodings in URLs parts (this is especially useful in
7333 combination with map lookups).
7334 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
7336 *) Renamed the macro escape_uri() to ap_escape_uri() which was
7337 forgotten (because it was a macro) in the symbol renaming process.
7338 [Ralf S. Engelschall]
7340 *) Fix some inconsistencies related to the scopes of directives. The only
7341 user visible change is that the directives `UseCanonicalName' and
7342 `ContentDigest' now use the (more correct) `Options' scope instead of
7343 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
7345 *) Using DSO, the Server token was being mangled. Specifically, the
7346 module's token was being added first before the Apache token. This
7347 has been fixed. [Jim Jagielski]
7349 *) Major overhaul of mod_negotiation.c, part 2.
7350 - properly handle "identity" within Accept-Encoding.
7351 - allow encoded variants in RVSA negotiation and let them appear in
7352 the Alternates field using the non-standard "encoding" tag-list.
7353 - fixed both negotiation algorithms so that an explicitly accepted
7354 encoding is preferred over no encoding if "identity" is not
7355 included within Accept-Encoding.
7356 - added ap_array_pstrcat() to alloc.c for efficient concatenation
7357 of large substring sequences.
7358 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
7361 *) Major overhaul of mod_negotiation.c, part 1.
7362 - cleanups to mod_negotiation comments and code structure
7363 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
7364 support for everything in the upcoming HTTP/1.1
7365 revision (draft-ietf-http-v11-spec-rev-06.txt).
7366 - language tag matching also handles tags with more than 2
7368 - empty Accept, Accept-Language, Accept-Charset headers are
7369 processed correctly; previously an empty header would make all
7370 values acceptable instead of unacceptable.
7371 - allowed for q values in Accept-Encoding
7372 - added support for transparent content negotiation (rfc2295 and
7373 rfc2296) (though we do not implement all features in these drafts,
7374 e.g. no feature negotiation). Removed old experimental version.
7375 - implemented 'structured entity tags' for better cache correctness
7376 (structured entity tags ensure that caches which can deal with Vary
7377 will (eventually) be updated if the set of variants on the server
7379 - this involved adding a vlist_validator element to request_rec
7380 - this involved adding the ap_make_etag() function to the global API
7381 - modified guessing of charsets used by Apache negotiation algorithm
7382 to guess 'no charset' if the variant is not a text/* type
7383 - added code to sort multiviews variants into a canonical order so that
7384 negotiation results are consistent across backup/restores and mirrors
7385 - removed possibility of a type map file resolving to another type map
7386 file as its best variant

7404 rather late (too late for some invocations of TestCompile).
7405 This improves the make environment available to TestCompile and
7406 the *.module scripts. [Martin Kraemer]
7408 *) The hashbang emulation code in ap_execve.c would interpret
7409 #!/hashbang/scripts correctly, but failed to fall back to a
7410 standard shell for scripts which did NOT start with #!
7411 Now SHELL_PATH is started in these cases. [Martin Kraemer]
7413 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
7416 *) Update APXS manual page: some -q option arguments were missing
7417 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
7419 *) Cleanup the command line options: `-?' was documented to show
7420 the usage list but does it with an error because `?' is not a valid
7421 command. OTOH a lot of users expect `-h' to print such a usage list and
7422 instead are annoyed for ages by our huge unreadable list of directives.
7423 So we now changed the command line options this way:
7425 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
7426 very similar to the popular linker option.
7428 Intent: while -l gives the small list of modules, -L now gives the
7429 large list of directives implemented by these modules. This is also
7430 consistent with -v (short version info) and -V (large version info).
7432 Intent: it's now the expected option ;-)
7433 The manual page was adjusted accordingly.

7436 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
7437 wasn't defined. [Rick Franchuk <rickf transpect.net>]
7439 *) Removed recently introduced bugs and disfigurements in APACI:
7440 o fixed argument line processing: using $args was broken: It was not
7441 initialized and using args="$args $apc_option" and even args="$args
7442 \"$apc_option\"" fails in the second processing round for any arguments
7443 containing whitespaces. The only correct way is to use the construct
7444 "$@" (but not possible here) or iterate _both_ times over the implicit
7445 argument line (no argument to for-loop) which is what we now use.
7446 o make --with-layout=Apache the default without creating
7447 redundancy (copying the --with-layout block in the argument parsing
7448 loop). We achieve this by using the "$@" construct together with the
7449 `set' command to prepend --with-layout=Apache to the command line in
7450 case --with-layout is not used.
7451 o fixed auto-suffix handling now that config.layout exists.
7452 Paths which are auto-suffixed are marked with a trailing plus sign in
7453 config.layout and every path now can be marked this way (not only the
7454 four paths for which we do it currently). Additionally the suffix is
7455 no longer a static one. Instead it's now `/<target>' where <target> is
7456 the argument of the --target option or per default `httpd'.
7457 o allow also tabs (and only spaces) where we match whitespaces
7458 o various fixes and cleanups related to used shell coding style
7459 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7460 o trimmed output of --help to fit into 80 columns
7461 [Ralf S. Engelschall]
7463 *) Added two new core API functions, ap_single_module_configure() and
7464 ap_single_module_init(), which are now used by mod_so to configure a module

7483 [Tom Serkowski <tks bsdi.com>] PR#3453
7485 *) Make generation of src/Configuration.apaci more robust: It failed to
7486 differenciate between modules when one module name was a postfix of
7487 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
7488 just XXX (think about totally non-standard names like "apache_ssl", too).
7489 [Ralf S. Engelschall] PR#3380
7491 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
7492 since 1.3b7) and make whitespace handling more robust (it failed horrible

7494 [Ralf S. Engelschall] PR#3240
7496 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
7497 creates an external package shadow tree in DIR before the local build
7498 shadow tree is generated under DIR. This way one can have the extracted
7499 Apache distribution tree read-only on NFS or CDROM and still build Apache
7500 from these sources. An automatically triggered VPATH-like mechanism is

7519 They can occur multiple times and their arguments (`xxx') are passed AS
7520 IS to the compiler/linker command. [Ralf S. Engelschall]
7522 *) Fixed possible (but harmless in practice) bug in the DBM lookup
7523 procedure of mod_rewrite: very long keys were truncated.
7524 [Ralf S. Engelschall]
7526 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
7527 identifier, currently "Apache" and "GNU" are pre-defined in the file
7528 config.layout. Custom layouts are possible by using FILE:ID as the
7529 argument where the layout ID is taken from FILE.
7531 The config.layout file consists of <Layout ID>..</Layout> sections
7532 where inside those sections "path_variable: path_value" pairs can be
7533 specified. These lines are converted to path_variable='path_value'.
7535 *) Add a DefaultLanguage directive so that files missing a language
7536 extension (e.g., .fr, .de) can be labelled as being some other
7537 default language. DefaultLanguage can appear in <Directory> and
7538 <Files> containers as well as .htaccess files. [Paul Sutton]
7541 *) Fix TARGET configuration when configuring and installing using
7542 APACI configure. TARGET now defines the basename of the configuration
7543 file, startup script, manual page, etc. log_error_core() now reports
7544 the server binary name given by argv[0]. TARGET can now also be defined
7545 with --target=TARGET parameter passed to APACI configure.

7654 supported for the option argument: first BEGIN:foo which permutes module
7655 mod_foo with the begin of the module list, i.e. it `moves' the module to
7656 the begin of the list (gives it lowest priority). And second foo:END

7866 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this

7880 *) Make PrintPath work generically instead of having one version
7881 strictly for OS/2. [Jim Jagielski, Brian Havard]
7883 *) Fix the recently introduced C header file checking: We now use the C
7884 pre-processor pass only (and no longer the complete compiler pass) to
7885 determine whether a C header file exists or not. Because only this way
7886 we're safe against inter-header dependencies (which caused horrible
7887 portability problems). The only drawback is that we now have a CPP
7888 configuration variable which has to be determined first (we do a similar
7889 approach as GNU Autoconf does here). When all fails the user still has
7890 the possibility to override it manually via APACI or src/Configuration.
7891 As a fallback for the header check itself we can directly check the
7892 existance of the file under /usr/include, too.

7941 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
7943 *) mod_expires will now act on content that is not sent from a file
7944 on disk. Previously it would never add an Expires: header to
7945 any response that did not come from a file on disk; the only
7946 case where it still doesn't (and can't) add one for that type of
7947 content is if you are using a modification date based setting.

7963 a common problem of (mis-administrated?) IIS servers, make the apache
7964 proxy immune to these errors (and ignore the duplicates, but log
7965 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
7967 *) The <IfModule and <IfDefine block starting directives now only
7968 allow exactly one argument. Previously, the optional negation
7969 character '!' could be separated by whitespace without a syntax
7970 error being reported, albeit defeating the IfModule functionality
7971 (enclosed directives would ALWAYS be executed). By using the
7972 stricter syntax, these hard-to-track errors can be avoided.
7975 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
7976 cause the standalone FancyIndexing directive to logically OR
7977 into any existing IndexOptions settings rather than wiping
7978 them out. [Ken Coar]
7980 *) Changes in ftp proxy: make URL parsing simpler by using the
7982 + Add display of the "current directory" in cases where it's
7983 different from the supplied path (e.g., ftp://user@host/ lives
7984 in /home/user, not in /, therefore clicking on "../" in the
7985 starting directory might send us to /home/).
7986 + When ftp login fails, (esp. when a user name was part of the
7987 URL already), we now return [401 Unauthorized ] to allow the
7988 browser to pop up an authorization dialog. This makes passwords
7989 slightly less visible (they don't appear in the regular log files)
7990 and implements a functionality that other www proxy servers
7994 *) Triggered by the recent "Via:" header changes, the proxy module would
7995 dump core for replies with invalid headers (e.g., duplicate
7996 "HTTP/1.0 200 OK" lines). These errors are now logged and the
7997 core dump is avoided. Also, broken replies are not cached.

8061 *) When READing a request in ExtendedStatus mode, the "old"
8062 vhost, request and client information is not displayed.
8065 *) STATUS is no longer available. Full status information now
8066 run-time configurable using the ExtendedStatus directive.
8069 *) SECURITY [CAN-1999-1199] (cve.mitre.org):
8070 Eliminate O(n^2) space DoS attacks (and other O(n^2)
8071 cpu time attacks) in header parsing. Add ap_overlap_tables(),
8072 a function which can be used to perform bulk update operations
8073 on tables in a more efficient manner.
8076 *) SECURITY: Added compile-time and configurable limits for
8077 various aspects of reading a client request to avoid some simple
8078 denial of service attacks, including limits on maximum request-line
8079 size (LimitRequestLine), number of header fields (LimitRequestFields),
8080 and size of any one header field (LimitRequestFieldsize). Also added
8081 a configurable directive LimitRequestBody for limiting the size of the

8100 *) The 'status' module will now show the process pid's and their
8101 state even without full STATUS accounting. [Jim Jagielski]
8103 *) Restore the client IP address to the error log messages, this
8104 was lost during the transition from 1.2 to 1.3. Add a new
8105 function ap_log_rerror() which takes a request_rec * and
8106 formats it appropriately. [Dean Gaudet] PR#2661
8108 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
8109 whitespace in input lines -- including within quoted strings.
8111 but leading and trailing whitespace should continue to be

8114 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
8115 the ugly use of an env. variable and use command-line args for
8116 alternate $PATH. Make more like advanced 'type's as well.

8127 directory was renamed to src/os/os2/ for consistency.
8128 [Brian Havard, Ralf S. Engelschall]
8130 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
8131 files (here modules) against other DSO files (here shared libraries).
8132 This is done by determining a subset of LIBS which can be safely used for
8133 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
8134 disabled for all platforms to avoid problems with this (experimental)

8272 least one "mmapfile" directive is present in the configuration.
8273 This experimental module has to do some black magic to operate
8274 inside the current API and thus creates side-effects for other
8275 modules under some circumstances.

8278 *) Add conservative ticks around more egrep arguments in top-level configure
8279 to avoid problems under brain-dead platforms like Digital UNIX (OSF1).

8282 *) mod_rewrite created RewriteLock files under the UID of the parent
8283 process, thus the child processes had no write access to the files.
8284 Now a chown() is done on the file to the uid of the children,
8285 if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341
8287 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
8288 TestCompile) instead of defining them manually in conf.h based on less
8289 accurate platform definitions. This way we no longer have to fiddle with
8290 OS-type and/or OS-version identifiers to discover whether a system header
8291 file exists or not. Instead we now directly check for the existence of
8292 those esoteric ones.

8299 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
8300 modules to load their own modules dynamically. This improves mod_perl
8301 and mod_php3 when these modules are loaded dynamically into Apache.
8304 *) Cache a proxied request in the event that the client cancels the

8332 *) The APACI libexecdir was not extended with an "apache/" subdir
8333 if the installation prefix didn't already contain "apache", but
8334 it should be because the DSO files are Apache-specific. Now
8335 libexecdir is treated the same way sysconfdir, datadir, localstatedir

8389 directory, bail out of the request with an error message. [W G Stoddard]

8392 these are treated by Win32 as if they are ".." but are not detected by
8393 other machinery within Apache. This is something of a kludge but
8394 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
8396 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
8397 pools and thus pollutes libap (until the pool stuff is moved there).
8400 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
8401 but case-insensitive platforms). New #define for this added to conf.h

8411 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
8412 remove some of the classical hurdles for new users when setting up
8413 Apache. This is done per default because it is useful for the average
8414 user. Package authors can use the --without-confadjust option to disable
8415 these configuration adjustments.
8416 [Ralf S. Engelschall]
8418 *) Added an EXTRA_DEPS configuration parameter which can be used
8419 to add an extra Makefile dependency for the httpd target, for instance
8420 to external third-party libraries, etc.
8421 [Ralf S. Engelschall]
8423 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
8424 as <IfModule>..</IfModule> sections) which can be used to skip or process
8425 contained commands dependend of ``-D PARAMETER'' options on the command
8426 line. This can be used to achieve logical conditions like <IfDefine
8427 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
8428 and thus especially can be used for conditionally loading DSO-based
8429 modules via LoadModule, etc. [Ralf S. Engelschall]

8436 truncated which forced following HTTP headers to be data in the HTTP

8440 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
8441 in top-level configure script to avoid sed fails on some platforms (for
8442 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
8443 output of Awk. [Bill Houle <bhoule sandiegoca.ncr.com>] PR#2435
8445 *) Improve performance of directory listings (mod_autoindex) by comparing
8446 integer keys (last-modified and size) as integers rather than converting
8447 them to strings first. Also use a set of explicit byte tests rather
8448 than strcmp() to check for parent directory-ness of an entry. Oh, and
8449 make sure the parent directory (if displayed) is *always* listed first
8450 regardless of the sort key. Overall performance winnage should be good
8451 in CPU time, instruction cache, and memory usage, particularly for large
8452 directories. [Ken Coar]
8454 *) Add a tiny but useful goody to APACI's configure script: The generation
8455 of a config.status script (as GNU Autoconf does) which remembers the used
8456 configure command and hence can be used to restore the configuration by
8457 just re-running this script or for remembering the configuration between
8459 [Ralf S. Engelschall]
8461 *) Add httpd -t (test) option for running configuration syntax tests only.
8462 If something is broken it complains and exits with a return code
8463 non-equal to 0. This can be used manually by the user to check the Apache
8464 configuration after editing and is also automatically used by apachectl
8465 on (graceful) restart command to make sure Apache doesn't die on restarts
8466 because of a configuration which is now broken since the last (re)start.
8467 This way `apachectl restart' can be used inside cronjobs without having
8468 to expect Apache to be falling down. Additionally the httpd -t can be run
8469 via `apachectl configtest'.

8609 spawn_child was obsoleted and moved to compat.h
8612 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
8613 programs: ap_spawn_child_err() is used and the Win32 case now uses
8614 CreateProcess() instead of a low-level execl() (which caused problems in
8615 the past under Win32).

8618 *) A few cosmetics and trivial enhancements to APXS to make the
8619 generated Makefile more user friendly. [Ralf S. Engelschall]
8621 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
8622 was updated to use the normal apache error processing, thereby allowing
8623 proxy errors to be treated by ErrorDocument's as well. For this
8624 purpose, a new module-to-core communication variable "error-notes"
8625 was introduced; the proxy (and possibly other modules) communicates
8626 its error text using this variable. Its content is copied to a new
8627 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
8628 The old proxy special error routine ap_proxy_log_uerror()
8629 was replaced by regular ap_log_error() calls, many messages were made

8633 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
8636 *) Transform the configure message "You need root privileges for suEXEC"
8637 from a fatal error into a (more friendly) warning because the building
8638 ("make") of Apache we can allow, of course. Root privileges are needed
8639 only for the installation step ("make install"). So make sure the

8707 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
8709 *) The Makefiles assumed that DSO files are build via $(LD). This
8710 is broken for two reasons: First we never defined at least LD=ld
8711 somewhere to make sure this works (it was silently assumed that most Make
8712 provide a built-in LD definition - ARGL!) and second using the generic LD
8713 variable is not the truth. Instead a special variable named LD_SHLIB is
8714 reasonable because although "ld" is usually the default, the command for
8715 building DSO files can be "libtool" or even "cc" on some systems.
8716 [Ralf S. Engelschall]
8718 *) Replace the AddVersionPlatform directive with ServerTokens which
8719 provides for more control over the format of the Server:

8732 - make OSDIR also automatically be relative to src/ like INCDIR
8733 - SUBDIRS is now generated in src/Makefile only and not in
8734 Makefile.config because it is a local define for this location.
8735 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
8736 any Makefile but make sure that at least the "-K inline" is kept in
8738 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
8739 - updated the dependencies theirself
8740 - removed not existing SHLIB variable from "clean" targets
8741 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
8742 already exists and OBJS_PIC are also just plain objects and have not
8743 directly to do with "shared" things. The only difference is that they
8744 contain PIC. So OBJS_PIC is the more canonical name.
8745 - Updated the Makefile-dependency lines for OBJS_PIC
8746 - Removed the Makefile-dependency line in Configure to avoid double
8748 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
8749 of xxx.lo as GNU libtool does with its PIC objects
8750 - reduce local complexity in modules Makefile.tmpl by moving the last
8751 existing target "depend" to the generation section in Configure, too.
8752 - removed the historical $(SPACER) which was used in the past together
8753 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
8754 is no longer needed.
8755 - force the build and run of the gen_xxx programs under main/ as the
8756 first step before building the objects because it looks cleaner

8768 *) When opening "configuration" files (like httpd.conf, htaccess
8769 and htpasswd), Apache will not allow them to be non-/dev/null
8770 device files. This closes a DoS hole. At the same time,
8771 we use ap_pfopen to open these files to handle timeouts.
8772 [Jim Jagielski, Martin Kraemer]
8774 *) Apache will now log the reason its httpd children exit if they exit
8775 due to an unexpected signal. (It requires a new porting define,
8776 SYS_SIGLIST, which if defined should point to a list of text
8777 descriptions of the signals available. See PORTING.) [Dean Gaudet]
8779 *) WIN32: chdir() doesn't make sense in a multithreaded environment
8780 like WIN32. Before, Win32 CGI's could have had sporadic failures
8781 if a chdir call from one thread was made between another chdir call
8782 and a spawn in another thread. So, for now don't chdir for CGI scripts
8783 in WIN32. The current CGI "spec" is unclear as to whether it's
8784 necessary. Long-term fix is to either serialize the chdir/spawn combo
8785 or use WIN32 native calls to spawn a process. This temp fix was
8786 necessary to remove this as a showstopper for 1.3's release.
8789 *) Cleanup the suEXEC support in APACI and make it more safe:
8790 1. Add big fat hint in INSTALL about risks and to read the
8791 htdocs/manual/suexec.html document before using the suexec-related
8793 2. Make sure the user has at least provided one --suexec-xxxx option
8794 (specifies suEXEC parameters) in addition to --enable-suexec option.
8795 If only --enable-suexec is given APACI stops with a hint to INSTALL
8796 and htdocs/manual/suexec.html documents.
8797 3. Provide two additional --suexec-xxxx options to make the suEXEC
8798 configuration complete (especially for package maintainers who else
8799 had to patch the source tree) by providing ways to configure minimal
8800 UID/GID and safe PATH, too.
8801 [Ralf S. Engelschall]
8803 *) Cleanup of the `configure --shadow' process:
8804 - make sure the configure script creates its temporary files in the
8805 shadow tree to avoid conflicts with parallel configure runs
8806 - removed unnecessary option "-r" from "rm" call for Makefiles
8807 - make sure the configure scripts creates the shadow-wrapper Makefile
8808 only when no shadow trees already exists
8809 - make sure "make distclean" removes the shadow-wrapper Makefile but only
8810 when no more shadow trees exists
8811 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
8812 as fast (in the past it needed 70sec, now it runs just 38sec)
8813 - make sure CVS does not complain about the created files
8814 Makefille.<gnutriple> and directories src.<gnutriple>
8815 [Ralf S. Engelschall]
8817 *) Added the ap_add_version_component() API routine and the
8818 AddVersionPlatform core directive. The first allows modules to
8819 declare themselves in the Server response header field value,
8820 augmenting the SERVER_SUBVERSION define in the Configuration file
8821 with run-time settings (more useful in a loadable-module environment).
8822 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
8823 into the server version string. [Ken Coar] PR#2056
8825 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
8828 *) Emit the "Accept-Range" header for the default handler.
8829 [Brian Behlendorf] PR#1464
8831 *) Add a note to httpd.conf-dist that apache will on some systems fail
8832 to start when the Group # is set to a negative or large positive value.
8835 *) Make sure the module execution order is correct even when some modules
8836 are loaded under runtime (`LoadModule') via the DSO mechanism:
8837 1. The list of loaded modules is now a dynamically allocated one
8838 and not the original statically list from modules.c
8839 2. The loaded modules are now correctly setup by LoadModule for
8840 later use by the AddModule command.
8841 3. When the DSO mechanism for modules is used APACI's `install'
8842 target now enables all created `LoadModule' lines per default because
8843 this is both already expected by the user _and_ needed to avoid
8844 confusion with the next point and reduces the Makefile.tmpl complexity
8845 4. When the DSO mechanism for modules is used, APACI's `install'
8846 target now additionally makes sure the module list is reconstructed
8847 via a complete `ClearModuleList+AddModule...' entry.
8848 5. The support tool `apxs' now also makes sure an AddModule command
8849 is added in addition to the LoadModule command.
8850 6. The modules.c generation was extended to now contain two
8851 comments to make sure no one is confused by the confusing terminology
8852 of loading/linking (we use load=link+load & link=activate instead of
8853 the obvious load=activate & link=link :-( )
8854 This way now there is no longer a difference under execution time between
8855 statically and dynamically linked modules.
8856 [Ralf S. Engelschall]
8858 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
8859 Big Symbol Renaming. [Ralf S. Engelschall]
8861 *) Add a comment to mod_example.c showing the format of a FLAG command
8864 *) Standardized the time format in mod_status to match that of other
8865 places in the code (e.g. DATE_GMT). PR#1551
8867 *) Fix handling of %Z in timefmt strings for those platforms with no time
8868 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
8871 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
8872 feature compatible with 'UseCanonicalName off' by changing
8873 r->server->server_hostname to ap_get_server_name(). And I changed some
8874 functions which use r->server->port to use ap_get_server_port() instead,
8875 because if there's no Port directive in the config r->server->port is 0.
8878 *) get/set_module_config are trivial enough to be better off inline. Worth
8879 1.5% performance boost. [Dean Gaudet]
8881 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
8882 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
8885 *) [BS2000 security] BS2000 needs an extra authentication to initialize
8886 the task environment to the unprivileged User id. Otherwise CGI scripts
8887 would have a way to gain super user access. [Martin Kraemer]
8889 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
8890 absolute path, only log base name of logging source as is done
8891 in unix. [Martin Kraemer]
8893 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
8894 the encoding type from the Accept-Encoding header (if it's there)
8895 and use it in the response, as that's probably what it'll be expecting.
8896 [<Ronald.Tschalaer psi.ch>]
8898 *) Fix to mod_alias: translate_alias_redir is dealing with
8899 a URI, not a filename, so the check for drive letters for win32
8900 and emx is not necessary. [Dean Gaudet]
8902 *) WIN32: Allow .cmd as an executable extension.
8903 [Kari Likovuori <Kari.Likovuori mol.fi>] PR#2146
8905 *) Make Apache header files, and some variables, C++ friendly.
8906 [Michael Anderson's <mka redes.int.com.mx>]
8908 *) Child processes can now "signal" (by exiting with a status
8909 of APEXIT_CHILDFATAL) the parent process to abort and
8910 shutdown the server if the error in the child process was
8911 fatal enough. [Jim Jagielski]
8913 *) mod_autoindex's find_itme() was sensitive to MIME type case.
8914 [Jim Jagielski] PR#2112
8916 *) Make sure the referer_log and agent_log entries in the default httpd.conf
8917 file are also adjusted for the actual relative installation paths.
8918 [Ralf S. Engelschall] PR#2175
8920 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
8922 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
8925 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
8926 Additionally the checks for finding the vendor DSO library were moved
8927 from mod_so.c to Configure because first it needs $PLAT etc. and second
8928 mod_so already uses an abstraction layer and does not fiddle with the
8929 vendor functions itself.
8930 [Jens-Uwe Mager, Ralf S. Engelschall]
8932 *) PORT: Some optimization defines for NetBSD
8933 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
8935 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
8936 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
8938 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
8939 AIX variants should work fine, too. Even AIX 3.x should work). This is
8940 accomplished by using the free DSO emulation code from Jens-Uwe Mager
8941 which we put into a os/unix/os-dso-aix.c file.
8942 [Ralf S. Engelschall]
8944 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
8945 that we should use NET_SIZE_T == int but the include files force size_t.
8946 [Ralf S. Engelschall]
8948 *) Fix two bugs in select() handling in http_main.c.
8951 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
8952 is unset (as it is in situations like timeouts) where it is unclear
8953 whether errno is set or not. [Martin Kraemer]
8955 *) Just having APACI's localstatedir is too general and not enough for most
8956 of the systems. 1.3b6 again required manual APACI patches by package
8957 maintainers from Red Hat and FreeBSD because for their filesystem layout a
8958 little bit more flexibility in configuring the paths is needed. Hence we
8959 provide three additional configure options (--runtimedir, --logfiledir,
8960 --proxycachedir) which now can be used for more granular adjustments if
8961 --localstatedir is not enough to fit the particular needs. As a nice
8962 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
8963 [Ralf S. Engelschall]
8965 *) Make the install root for "make install" in APACI's Makefile overrideable
8966 by package authors. This way we are even more friendly to package
8967 maintainers (especially Debian and Red Hat) who build for the real prefix
8968 via "configure --prefix=/<real>" but use a different local prefix via
8969 "make root=/tmp/apache install" for rolling the package without bristling
8970 the target location on their system.
8971 [Ralf S. Engelschall]
8973 *) Workaround sed limitations in APACI's configure script by now
8974 substituting in chunks of 50 commands (because for instance HPUX's vendor
8975 sed has a limit of max. 98 commands)
8976 [Ralf S. Engelschall] PR#2136
8978 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
8979 [Ralf S. Engelschall] PR#2140
8981 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
8982 RENAMING process because they are defined as pre-processor macros instead
8983 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
8984 [Ralf S. Engelschall]
8986 *) Workaround braindead AWK's when generating ap_config.h: The split() and
8987 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
8988 [Ralf S. Engelschall] PR#2139
8990 *) Various bugfixes and cleanups for the APACI configure script:
8991 o fix IFS handling for _nested_ situation
8992 o fix Perl interpreter search: take first one found instead of last one
8993 o fix DSO consistency check
8994 o print error messages to stderr instead of stdout
8995 o add install-quiet for --shadow situation to Makefile stub
8996 o reduce complexity by avoiding sed-hacks for rule and module list loops
8997 [Ralf S. Engelschall]
8999 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
9001 *) Make sure the input field separator (IFS) shell variable is explicitly
9002 initialized correctly before _every_ `for' loop and also restored after
9003 the loops. [Ralf S. Engelschall]
9005 *) Make sure that "make install" doesn't overwrite the `mime.types' and
9006 `magic' files from an existing Apache installation. Because people often
9007 customize these for own MIME and content types.

9013 *) Fix the path to the ScoreBoardFile in the install-config target, too.
9014 [Ralf S. Engelschall] PR#2105
9016 *) Let "configure" clear out the users parameters (provided as shell

9018 exported them (which is not needed, but some users do it).
9019 [Ralf S. Engelschall] PR#2101
9021 *) Provide backward compatibility from some old src/Configuration.tmpl
9022 parameter names to the canonical Autoconf-style shell variable names. For
9023 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
9024 but a hint message is displayed. [Ralf S. Engelschall]

9030 *) Make `configure --compat' more "compatible" by first
9031 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
9032 second by making sure the "avoid-bristling-suffix" /apache is not
9033 appended to sysconfdir, datadir, localstatedir and includedir when

9043 [Ralf S. Engelschall] PR#2089
9045 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
9047 *) If you start apache with the -S command line option it will dump
9048 out the parsed vhost settings. This is useful for folks trying
9049 to figure out what is wrong with their vhost configuration.
9050 (Other dumps may be added in the future.) [Dean Gaudet]
9052 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
9053 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
9056 *) Because /usr/local/apache is the default prefix the ``configure
9057 --compat'' option no longer has to set prefix, again. This way the
9058 --compat option honors a leading --prefix option. [Lars Eilebrecht]
9060 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
9061 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
9062 to avoid "discard const" warnings. [Ralf S. Engelschall]
9064 *) If a specific handler is set for a file yet the request still
9065 ends up being handled by the default handler, log an error
9066 message before handling it. This catches things such as trying
9067 to use SSIs without mod_include enabled. [Marc Slemko]
9069 *) Fix error logging for the startup case where ap_log_error() still uses
9070 stderr as the target. Now the default log level is honored here, too.
9071 [Ralf S. Engelschall]
9073 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
9074 long" errors when generating the MODULES entry for src/Makefile
9075 [Ben Hyde, Ralf S. Engelschall]
9077 *) Make sure src/Configure doesn't complain about the old directory
9078 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
9080 Changes with Apache 1.3b6
9082 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
9084 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
9085 interface via the similar but proprietary HP/UX shl_xxx-style system
9086 calls. [Ralf S. Engelschall]
9088 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
9089 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
9090 Make. [Ralf S. Engelschall]
9092 *) ++++ THE BIG SYMBOL RENAMING ++++
9093 To avoid symbol clashes with third-party code compiled into the server,
9094 we globally applied the prefix "ap_" to the following classes of
9096 - Apache provided general functions (e.g., ap_cpystrn)
9097 - Public API functions (e.g., palloc, bgets)
9098 - Private functions which we can't make static (because of
9099 cross-object usage) but should be (e.g., new_connection)
9100 For backward source compatibility a new header file named compat.h was
9101 created which provides defines for the old symbol names and can be used
9102 by third-party module authors.
9105 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
9106 problem under SVR4 is that there is no command flag to force the linker
9107 to export the global symbols of the httpd executable therewith they are
9108 available to the DSO's. Instead of problematic hacks like creating a
9109 dummy.so file (containing dummy references to all global symbols) the
9110 httpd binary is linked against, we use a clean trick stolen from Perl 5:
9111 Placing the Apache core code itself into a DSO library named libhttpd.so.
9112 This way the global symbols _HAVE_ to be exported and thus are available
9113 to any manually loaded DSO's under runtime. To reduce the impact to the
9114 user to null we go even further and create a stub httpd executable which
9115 automatically keeps track of the DSO library loading itself and thus
9116 hides the complete mechanism from the user. Although the generation of
9117 this DSO library is automatically triggered for platforms which
9118 essentially need it (mostly all SVR4-derivates) it can be also enabled
9119 manually via the Rule SHARED_CORE. This can be interesting in the future
9120 where we perhaps exploit this libhttpd.so mechanism for providing nifty
9121 features like graceful upgrades, or whatever.
9122 [Ralf S. Engelschall, Martin Kraemer]
9124 *) Build the libraries before building the rest of the tools. [Ben Hyde]
9126 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
9127 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
9128 conventions while "clean" removes only stuff created by "all" targets,
9129 "distclean" additionally removes the stuff from the configuration
9130 process. This way "make distclean" (hence the name) provides a fresh
9131 source tree as it was for distribution.
9132 [Ralf S. Engelschall]
9134 *) Allow top-level (APACI) Makefile to break on build errors
9135 the same way the src/ subtree Makefiles breaks on them by replacing the
9136 initial APACI sed-subdir-display-kludge with a more clean
9137 variable-passing-solution: variable SDP can optionally hold the subdir
9138 prefix which is consistently used for displaying the subdir movement.
9139 This way even the top-level Makefile can stop correctly on errors as the
9140 user expects. [Ralf S. Engelschall]
9142 *) Fixed ordering of argument checks for RewriteBase directive.
9143 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
9145 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
9146 indicating that a module is being compiled for dynamic loading. Also
9147 remove #define IS_MODULE from modules and add SHARED_MODULE define
9148 to the mak/dsp files. [Alexei Kosut]
9150 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
9151 since we are now logging APLOG_WARNING by default. [Roy Fielding]
9153 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
9155 *) Add documentation file and src/Configuration.tmpl entry for the
9156 experimental mod_mmap_static module. Because although it is and marked as
9157 an experimental one it is distributed and thus should be documented and
9158 prepared for configuration the same way as all others modules.
9159 [Ralf S. Engelschall]
9161 *) Add query (-q) option to apxs support tool to be able to manually query
9162 specific settings from apxs. This is needed for instance when you
9163 manually want to access Apache's header files and you need to assemble
9164 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
9165 [Ralf S. Engelschall]
9167 *) Now src/Configure uses a fallback strategy for the shared object support
9168 on platforms where no explicit information is available: If a Perl
9169 installation exists we ask it about its shared object support and if it's
9170 the dlopen-style one we shamelessly guess the compiler and linker flags
9171 for creating shared objects from Perls knowledge. Of course, the user is
9172 warning about what we are doing and informed that he should send us
9173 the guessed flags when they work. [Ralf S. Engelschall]
9175 *) Provide APACI --without-support option to be able to disable the build
9176 and installation of the support tools from the src/support/ area.
9177 Although its useful to have these installed per default we should provide
9178 a way to compile and install without them for backward-compatibility.
9179 [Ralf S. Engelschall]
9181 *) Add of the new APache eXtenSion (apxs) support tool for building and
9182 installing modules into an _already installed_ Apache package through the
9183 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
9184 this approach actually doesn't need the Apache source tree. The
9185 (APACI-installed) server package is enough, because this now includes the
9186 Apache C header files (PREFIX/include) and the new APXS tool
9187 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
9188 module authors to build their Apache modules _OUTSIDE_ the Apache source
9189 tree while avoiding them to fiddle around with the totally platform
9190 dependend way of compiling DSO files. The tool supports all ranges of
9191 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
9192 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
9193 on-the-fly generate a minimalistic Makefile and sample module for the
9194 first step to provide both a quick success event and to demonstrate the
9195 APXS mechanism to module authors. [Ralf S. Engelschall]
9197 *) Fix core dumps in use of CONNECT in proxy.
9198 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
9200 *) Modify the log directives in httpd.conf-dist files to use CustomLog
9201 so that users have examples of how CustomLog can be used.
9204 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
9205 the Apache distribution tree. Until Apache 1.3 there was no real
9206 out-of-the-box batch-capable build and installation procedure for the
9207 complete Apache package. This is now provided by a top-level "configure"
9208 script and a corresponding top-level "Makefile.tmpl" file. The goal is
9209 to provide a GNU Autoconf-style frontend which is capable to both drive
9210 the old src/Configure stuff in batch and additionally installs the
9211 package with a GNU-conforming directory layout. Any options from the old
9212 configuration scheme are available plus a lot of new options for flexibly
9213 customizing Apache. [Ralf S. Engelschall]
9215 *) The floating point ap_snprintf code wasn't threadsafe.
9216 Had to remove the HAVE_CVT macro in order to do threadsafe
9217 calling of the ?cvt() floating point routines. [Dean Gaudet]
9219 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
9221 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
9222 [Jim Jagielski] PR#1901
9224 *) BUG: Configure was using TCC and CC inconsistently. Make sure
9225 Configure knows which CC we are using. [Jim Jagielski]
9227 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
9228 was defined in a parent directory. [Lars Eilebrecht]
9230 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
9231 a generic printf-style routine that can call arbitrary output
9232 routines. Use this to replace http_bprintf.c. Add new routines
9233 psprintf(), pvsprintf() which allocate the exact amount of memory
9234 required for a string from a pool. Use psprintf() to clean up
9235 various bits of code which used ap_snprintf()/pstrdup().
9238 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
9239 ap_snprintf() has different semantics and formatting codes than
9240 snprintf(). [Dean Gaudet]
9242 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
9243 is necessary on at least Solaris where the /etc/rc?.d scripts

9273 *) Allow %2F in two situations: 1) it is in the query part of the URI,
9274 therefore not exposed to %2F -> '/' translations and 2) the request
9275 is a proxy request, so we're not dealing with a local resource anyway.
9276 Without this, the proxy would fail to work for any URL's with
9277 %2f in them (occurs quite often in
9278 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]

9293 header if available. [Ralf S. Engelschall] PR#1183
9295 *) Reanimated the (still undocumented) proxy receive buffer size directive:
9296 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
9297 name was really too generic, added documentation for this directive to
9298 the mod_proxy.html and corrected the hyperlink to it in the

9307 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
9308 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
9309 and per default compiled support programs have manual pages - just to
9310 document our stuff a little bit more and to be able to do really
9311 Unix-like installations ;-) [Ralf S. Engelschall]
9313 *) Major cleanups to the Configure script to make it and its generated
9314 Makefiles again readable and maintainable: add SRCDIR option, removed
9315 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
9316 generated sections, consequently added Makefile headers with inheritance
9317 information, added subdir movement messages for easier following where
9318 the build process currently stays (more verbose then standard Make, less
9319 verbose than GNU make), same style to comments in the Configure script,
9320 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
9322 *) Add the new ApacheBench program "ab" to src/support/: This is derived
9323 from the ZeusBench benchmarking program and can be used to determine the
9324 response performance of an Apache installation. This version is
9325 officially licensed with Zeus Technology, Ltd. See the license agreement

9331 more have been marked CORE_EXPORT and are not intended for general
9332 use by modules. [Doug MacEachern, Dean Gaudet]
9334 *) mod_proxy was not clearing the Proxy-Connection header from
9335 requests; now it does. This did not violate any spec, however

9345 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
9347 *) Clean up some undocumented behavior of mod_setenvif related to
9348 "merging" two SetEnvIf directives when they match the same header
9349 and regex. Document that mod_setenvif will perform comparisons in
9350 the order they appear in the config file. Optimize mod_setenvif by
9351 doing more work at config time rather than at runtime.
9354 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
9355 to allow for modules to overrule them and to reduce redefinition
9356 warnings [Jim Jagielski]
9358 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
9361 *) Making the hard-coded cross-module function call mime_find_ct() (from
9362 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
9363 checking is really called even for proxy requests except for URLs with
9364 HTTP schemes (because there we can optimize by not running the type
9365 checking hooks due to the fact that the proxy gets the MIME Content-type
9366 from the remote host later). This change cleans up mod_mime by removing
9367 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
9368 especially unbundles mod_proxy and mod_mime. This way they both now can
9369 be compiled as shared objects and are no longer tied together.
9370 [Ralf S. Engelschall]
9372 *) util.c cleanup and speedup. [Dean Gaudet]
9374 *) API: Clarification, pstrndup() will always copy n bytes of the source
9375 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
9377 *) Mark module command_rec and handler_rec structures const so that they
9378 end up in the read-only data section (and are friendlier to systems
9379 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
9381 *) Add check to the "Port" directive to make sure the specified
9382 port is in the appropriate range. [Ben Hyde]
9384 *) Performance improvements to invoke_handler().
9385 [Dmitry Khrustalev <dima bog.msu.su>]
9387 *) Added support for building shared objects even for library-style modules
9388 (which are built from more than one object file). This now provides the
9389 ability to build mod_proxy as a shared object module. Additionally
9390 modules like mod_example are now also supported for shared object
9391 building because the generated Makefiles now no longer assume there is at
9392 least one statically linked module. [Ralf S. Engelschall]
9394 *) API: Clarify usage of content_type, handler, content_encoding,
9395 content_language and content_languages fields in request_rec. They
9396 must always be lowercased; and the strings pointed to shouldn't
9397 be modified (you must copy them to modify them). Fix a few bugs
9398 related to this. [Dean Gaudet]
9400 *) API: Clarification: except for RAW_ARGS, all command handlers can
9401 treat the char * parameters as permanent, and modifiable. There
9402 is no need to pstrdup() them. Clean up some needless pstrdup().
9405 *) Now mod_so keeps track of which module shared objects with which names
9406 are loaded and thus avoids multiple loading and unloading and irritating
9407 error_log messages. [Ralf S. Engelschall]
9409 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
9410 environment variable in the apache core. But that tweaking interferes
9411 with mod_setenv. So don't tweak if the user has specified an explicit
9412 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888

9417 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's

9422 *) Various improvements to the configuration and build support for compiling
9423 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
9424 OSF1 support with GCC and vendor compilers was added. This way shared
9425 object support is now provided out-of-the-box for FreeBSD, Linux,
9426 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
9427 [Ralf S. Engelschall]
9429 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
9430 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
9431 and USE_OS2_SCOREBOARD. [Dean Gaudet]
9433 *) Fix one more special locking problem for RewriteMap programs in
9434 mod_rewrite: According to the documentation of flock(), "Locks are on
9435 files, not file descriptors. That is, file descriptors duplicated
9436 through dup(2) or fork(2) do not result in multiple instances of a lock,
9437 but rather multiple references to a single lock. If a process holding a
9438 lock on a file forks and the child explicitly unlocks the file, the
9439 parent will lose its lock.". To overcome this we have to make sure the
9440 RewriteLock file is opened _AFTER_ the childs were spawned which is now
9441 the case by opening it in the child_init instead of the module_init API
9442 hook. [Ralf S. Engelschall] PR#1029
9444 *) Change to Location and LocationMatch semantics. LocationMatch no
9445 longer lets a single slash match multiple adjacent slashes in the
9446 URL. This change is for consistency with RewriteRule and
9447 AliasMatch. Multiple slashes have meaning in URLs that they do
9448 not have in (some) filesystems. Location on the other hand can
9449 be considered a shorthand for a more complicated regex, and it
9450 does match multiple slashes with a single slash -- which is
9451 also consistent with the Alias directive.

9454 *) Fix bug with mod_mime_magic causing certain files, including files
9455 of length 0, to result in no response from the server.
9458 *) The Configure script now generates src/include/ap_config.h which
9459 contains the set of defines used when Apache is compiled on a platform.
9460 This file can then be included by external modules before including
9461 any Apache header files in case they are being built separately from
9462 Apache. Along with this change, a couple of minor changes were
9463 made to make Apache's #defines coexist peacefully with any autoconf
9464 defines an external module might have. [Rasmus Lerdorf]
9466 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9467 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9468 chance by the API to initialize its per-server configuration and thus
9469 receives the wrong one from the main server. This is now avoided by
9470 remembering the server together with the config structure while
9471 configuring and later assuming there is no config when we see a
9472 difference between the remembered server and the one calling us.
9473 [Ralf S. Engelschall] PR#1790
9475 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9476 is automatically disabled under configure time when the dbm_xxx functions
9477 are not available. Second, two heavy source code errors in the DBM
9478 support code were fixed. This makes DBM RewriteMap's usable again after
9479 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9481 *) Now all configuration files support Unix-style line-continuation via
9482 the trailing backslash ("\") character. This enables us to write down
9483 complex or just very long directives in a more readable way. The
9484 backslash character has to be really the last character before the
9485 newline and it has not been prefixed by another (escaping) backslash.

9497 *) WIN32: Preserve trailing slash in canonical path (and hence
9498 in PATH_INFO). [Paul Sutton, Ben Laurie]
9500 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
9501 depending on the rev of Solaris and what mixture of modules
9502 are in use. So it has been disabled, and Solaris is back to
9503 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9504 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9505 up static content only servers. Or it may fail unpredictably.
9506 [Dean Gaudet] PR#1779, 1854, 1904
9508 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9511 *) API: Rewrite of absoluteURI handling, and in particular how
9512 absoluteURIs match vhosts. Unless a request is a proxy request, a
9513 "http://host" url is treated as if a similar "Host:" header had been
9514 supplied. This change was made to support future HTTP/1.x protocols
9515 which may require clients to send absoluteURIs for all requests.
9517 In order to achieve this change subtle changes were made to the API. In a
9518 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9519 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9520 by the core, modules must set it during the post_read_request or
9521 translate_names phase.
9523 Plus changes to the virtualhost test suite for absoluteURI testing.
9525 This fixes several bugs with the proxy proxying requests to vhosts
9526 managed by the same httpd.
9529 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
9530 code from mod_rewrite. The vhost matching is now performed by a
9531 globally available function matches_request_vhost(). [Dean Gaudet]

9547 *) API: A new source module main/util_uri.c; It contains a routine
9548 parse_uri_components() and friends which breaks a URI into its component
9549 parts. These parts are stored in a uri_components structure called
9550 parsed_uri within each request_rec, and are available to all modules.
9551 Additionally, an unparse routine is supplied which re-assembles the URI
9552 components back to an URI, optionally hiding the username:password@ part
9553 from ftp proxy requests, and other useful routines. Within the structure,
9554 you find on a ready-for-use basis:
9555 scheme; /* scheme ("http"/"ftp"/...) */
9556 hostinfo; /* combined [user[:password]@]host[:port] */
9557 user; /* user name, as in http://user:passwd@host:port/ */
9558 password; /* password, as in http://user:passwd@host:port/ */
9559 hostname; /* hostname from URI (or from Host: header) */
9560 port_str; /* port string (integer representation is in "port") */
9561 path; /* the request path (or "/" if only scheme://host was given) */
9562 query; /* Everything after a '?' in the path, if present */
9563 fragment; /* Trailing "#fragment" string, if present */
9564 This is meant to serve as the platform for *BIG* savings in
9565 code complexity for the proxy module (and maybe the vhost logic).
9568 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
9569 ${map:key}) available for all location where a string is created in
9570 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
9571 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
9572 possible expansions are consequently usable at all string creation
9573 locations. [Ralf S. Engelschall]
9575 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
9576 and not 1) and the per-virtual-server merging of directives. Now all
9577 directives except `RewriteEngine' and `RewriteOption' are either
9578 completely overridden (default) or completely inherited (when
9579 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

9588 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
9589 (like SunOS and FreeBSD) which don't accept the locking of pipes
9590 directly. A new directive RewriteLock is introduced which can be used to
9591 setup a separate locking file which then is used for synchronization.

9609 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
9610 type but with a special post-processing for the looked-up value: It
9611 parses it into alternatives according to `|' chars and then only one
9612 particular alternative is chosen randomly (this is an essential
9613 functionality needed for balancing between backend-servers when using
9614 Apache as a Reverse Proxy. The looked up value here is a list of
9615 servers). Second, `int' with the built-in maps named `tolower' and
9616 `toupper' which can be used to map URL parts to a fixed case (this is an
9617 essential feature to fix the case of server names when doing mass
9618 virtual-hosting with the help of mod_rewrite instead of using
9619 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
9620 Jay Soffian <jay cimedia.com>] PR#1631
9622 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
9623 This directive lets Apache adjust the URL in Location-headers on HTTP
9624 redirect responses sent by the remote server. This way the virtually
9625 mapped area is no longer left on redirects and thus by-passed which is
9626 especially essential when running Apache as a reverse proxy.

9741 now ignores a leading x- when comparing encodings. It also
9742 preserves the encoding the client requests (for example if
9743 it requests x-gzip, then Apache will respond with x-gzip
9744 in the Content-Encoding header).

9747 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
9749 *) Added mod_so module to support dynamic loading of modules on Unix

9774 *) Yet another rearrangement of the source tree.. now all the common
9775 header files are in the src/include directory. The -Imain -Iap
9776 references in Makefiles have been changed to the simpler -Iinclude
9777 instead. In addition to simplifying the build a little bit, this
9778 also makes it clear when a module is referencing something in a
9779 other than kosher manner (e.g., the proxy including mod_mime.h).
9780 Module-private header files (the proxy, mod_mime, the regex library,
9781 and mod_rewrite) have not been moved to src/include; nor have
9782 the OS-abstraction files. [Ken Coar]
9784 *) Fix a bug where r->hostname didn't have the :port stripped
9785 from it. [Dean Gaudet]
9787 *) Tweaked the headers_out table size, and the subprocess_env
9788 table size guess in rename_original_environment(). Added
9789 MAKE_TABLE_PROFILE which can help discover make_table()
9790 calls that use too small an initial guess, see alloc.c.
9793 *) Options and AllowOverride weren't properly merging in the main
9794 server setting inside vhosts (only an issue when you have no
9795 <Directory> or other section containing an Options that affects
9796 a request). Options +foo or -foo in the main_server wouldn't
9797 affect the main_server's lookup defaults. [Dean Gaudet]
9799 *) Variable 'cwd' was being used pointlessly before being set.
9802 *) r->allowed handling cleaned up in the standard modules.
9805 *) Some case-sensitivity issues cleaned up to be consistent with

9811 *) mod_unique_id was erroneously generating a second unique id when
9812 an internal redirect occured. Such redirects occur, for example,
9813 when processing a DirectoryIndex match. [Dean Gaudet]
9815 *) API: table_add, table_merge, and table_set include implicit pstrdup()
9816 of the key and value. But in many cases this is not required
9817 because the key/value is a constant, or the value has been built
9818 by pstrcat() or other similar means. New routines table_addn,
9819 table_mergen, and table_setn have been added to the API, these
9820 routines do not pstrdup() their arguments. The core code and
9821 standard modules were changed to take advantage of these routines.
9822 The resulting server is up to 20% faster in some situations.
9824 Note that it is easy to get code subtly wrong if you pass a key/value
9825 which is in a pool other than the pool of the table. The only
9826 safe thing to do is to pass key/values which are in the pool of
9827 the table, or in one of the ancestors of the pool of the table.
9828 i.e. if the table is part of a subrequest, a value from the main
9829 request's pool is OK since the subrequest pool is a sub_pool of the
9830 main request's pool (and therefore has a lifespan at most as long as
9831 the main pool). There is debugging code which can detect improper
9832 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.

9838 MimeMagicFile directive then the module is not enabled.
9841 *) PORT: Some older *nix dialects cannot automatically start scripts
9842 which begin with a #! interpreter line (the shell starts the scripts

9848 *) API: "typedef array_header table" removed from alloc.h, folks should
9849 have been writing to use table as if it were an opaque type, but even
9850 some standard modules got this wrong. By changing the definition
9851 to "typedef struct table table" module authors will receive compile
9852 time warnings that they're doing the wrong thing. This change
9853 facilitates future changes with more sophisticated table
9854 structures. Specifically, module authors should be using table_elts()
9855 to get access to an array_header * for the table. [Dean Gaudet]
9857 *) API: Renamed new_connection() to avoid namespace collision with LDAP
9858 library routines. [Ken Coar, Rasmus Lerdorf]
9860 *) WIN32: mod_speling is now available on the Win32 platform.
9863 *) For clarity the following compile time definition was changed:
9865 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
9867 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
9868 and not be a general notice that the OS has mmap(). Now the
9869 HAVE_MMAP/SHMGET #defines strictly are informational that the
9870 OS has that method of shared memory; the type to use for
9871 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
9872 and USE_SHMGET_SCOREBOARD). This allows outside modules to
9873 determine if shared memory is available and allows Apache
9874 to determine the best method to use for the scoreboard.

10375 Changes with Apache 1.3b2 (there is no 1.3b1)
10377 *) TestCompile was not passing $LIBS [Dean Gaudet]
10379 *) Makefile.tmpl was not using $CFLAGS in the link phase.
10382 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
10383 rudimentary memory debugger which can be used on live servers with
10384 low impact -- it sets all allocated and freed memory bytes to 0xa5.
10385 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
10386 and free() for each object. This is far more expensive and should
10387 only be used for testing with tools such as Electric Fence and
10388 Purify. See main/alloc.c for more details. [Dean Gaudet]
10390 *) Configure uses a sh trap and didn't set its exitcode properly.
10391 [Dean Gaudet] PR#1159
10393 *) Yet another vhost revamp. Add the NameVirtualHost directive which
10394 explicitly lists the ip:port pairs that are to be used for name-vhosts.
10395 From a given ip:port, regardless what the Host: header is, you can
10396 only reach the vhosts defined on that ip:port. The precedence of
10397 vhosts was reversed to match other precedences in the config --
10398 the earlier vhosts override the later vhosts. All vhost matching was
10399 moved into http_vhost.[ch]. [Dean Gaudet]
10401 *) ap_inline can be used to force inlining. GNUC __attribute__() can
10402 be used for whatever reason is appropriate (i.e. format() warnings
10403 for printf style functions). Both are enabled only with
10404 gcc >= 2.7.x (so that we have fewer support issues with older
10405 versions). [Dean Gaudet]
10407 *) Fix support for Proxy Authentication (we were testing the response
10408 status too early). [Marc Slemko]
10410 *) CoreDumpDirectory directive directs where the core file is
10411 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
10412 received. [Marc Slemko, Dean Gaudet]
10414 *) PORT: Support for Atari MINT.
10415 [Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
10417 *) When booting, apache will now detach itself from stdin, stdout,
10418 and stderr. stderr will not be detached until after the config
10419 files have been read so you will be able to see initial error
10420 messages. After that all errors are logged in the error_log.
10421 This makes it more convenient to start apache via rsh, ssh,
10422 or crontabs. [Dean Gaudet] PR#523
10424 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10425 Also removed the auto-generated link to www.apache.org that was the
10426 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10428 *) send_fb would not detect aborted connections in some situations.
10431 *) mod_include would use uninitialized data when parsing certain
10432 expressions involving && and ||. [Brian Slesinsky] PR#1139
10434 *) mod_imap should only handle GET methods. [Jay Bloodworth]
10436 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10438 *) mod_autoindex improperly counted &escapes; as more than one
10439 character in the description. It also improperly truncated
10440 descriptions that were exactly the maximum length.
10443 *) RedirectMatch was not properly escaping the result (PR#1155). Also
10444 "RedirectMatch /advertiser/(.*) $1" is now permitted.
10447 *) mod_include now uses symbolic names to check for request success
10448 and return HTTP errors, and correctly handles all types of
10449 redirections (previously it only did temporary redirect correctly).
10450 [Ken Coar, Roy Fielding]
10452 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10453 r->filename. Since those two are meant to be in sync with each other
10454 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
10456 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
10457 ["Kaufman, Steven E" <Steven.Kaufman unisys.com>]
10459 *) Inetd mode (which is buggy) uses timeouts without having setup the
10460 jmpbuffer. [Dean Gaudet] PR#1064
10462 *) Work around problem under Linux where a child will start looping
10463 reporting a select error over and over.
10464 [Rick Franchuk <rickf transpect.net>] PR#1107, 987, 588
10466 *) Fixed error in proxy_util.c when looping through multiple host IP
10467 addresses. [Lars Eilebrecht] PR#974
10469 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10470 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10471 bytes before writing, but it will never split a log entry across a
10472 buffer boundary. [Dean Gaudet]
10474 *) API: the short_score record has been split into two pieces, one which
10475 the parent writes on, and one which the child writes on. As part of
10476 this change the get_scoreboard_info() function was removed, and
10477 scoreboard_image was exported. This change fixes a race condition
10478 in file based scoreboard systems, and speeds up changes involving the
10479 scoreboard in earlier 1.3 development. [Dean Gaudet]
10481 *) API: New register_other_child() API (see http_main.h) which allows
10482 modules to register children with the parent for maintenance. It
10483 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10485 *) API: New piped_log API (see http_log.h) which implements piped logs,
10486 and will use register_other_child to implement reliable piped logs
10487 when it is available. The reliable piped logs part can be disabled
10488 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10489 logs is only available on Unix. [Dean Gaudet]
10491 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10492 meets_conditions(). This allows conditional HTTP selection to be
10493 handled separately from the storing of the header fields, and provides
10494 the ability for CGIs to set their own ETags for conditional checking.
10495 [Ken Coar, Roy Fielding] PR#895
10497 *) Changes to mod_log_config to allow naming of format strings.
10498 Format nicknames are defined with "LogFormat fmt nickname", and can
10499 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
10502 *) New module, "mod_speling", which can help find files even when
10503 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
10505 *) API: New function child_terminate() triggers the child process to
10506 exit, while allowing the child finish what it needs to for the
10507 current request first.
10508 [Doug MacEachern, Alexei Kosut]
10510 *) Windows now defaults to using full status reports with mod_status.
10511 [Alexei Kosut] PR #1094
10513 *) *Really* disable all mod_rewrite operations if the engine is off.
10514 Some things (like RewriteMaps) were checked/performed even if they
10515 weren't supposed to be. [Ken Coar] PR #991
10517 *) Implement a new timer scheme which eliminates the need to call alarm() all
10518 the time. Instead a counter in the scoreboard for each child is used to
10519 show when the child has made forward progress. The parent samples this
10520 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10521 progress has been made in the timeout period. This reduces the static
10522 request best-case syscall count to 22 from 29. This scheme is only
10523 used by systems with memory-based scoreboards. [Dean Gaudet]
10525 *) The proxy now properly handles CONNECT requests which are sent
10526 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10528 *) A script called apachectl has been added to the support
10529 directory. This script allows you to do things such as
10530 "apachectl start" and "apachectl restart" from the command
10531 line. [Marc Slemko]
10533 *) Modules and core routines are now put into libraries, which
10534 simplifies the link line tremendously (among other advantages).
10537 *) Some of the MD5 names defined in Apache have been renamed to have
10538 an `ap_' prefix to avoid conflicts with routines supplied by
10539 external libraries. [Ken Coar]
10541 *) Removal of mod_auth_msql.c from the distribution. There are many
10542 other options for databases today. Rather than offer one option,
10543 offer none at this time. mod_auth_msql and other SQL database
10544 authentication modules can be found at the Apache Module Registry.
10545 http://modules.apache.org/ It would be nice to offer a generic
10546 mod_auth_sql option in the near future.
10548 *) PORT: BeOS support added [Alexei Kosut]
10550 *) Configure no longer accepts the -make option, since it creates
10551 Makefile on the fly based on Makefile.tmpl and Configuration.
10553 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
10554 of forcibly killing off all its processes and exiting without
10555 cleaning up. [Alexei Kosut]
10557 *) API: A new field in the request_rec, r->mtime, has been added to
10558 avoid gratuitous parsing of date strings. It is intended to hold
10559 the last-modified date of the resource (if applicable). An
10560 update_mtime() routine has also been added to advance it if
10561 appropriate. [Roy Fielding, Ken Coar]
10563 *) SECURITY: If a htaccess file can not be read due to bad permissions,
10564 deny access to the directory with a HTTP_FORBIDDEN. The previous
10565 behavior was to ignore the htaccess file if it could not be read.
10566 This change may make some setups with unreadable htaccess files
10567 stop working. [Marc Slemko] PR#817
10569 *) Add aplog_error() providing a mechanism to define levels of
10570 verbosity to the server error logging. This addition also provides
10571 the ability to log errors using syslogd. Error logging is configurable
10572 on a per-server basis using the LogLevel directive. Conversion
10573 of log_*() in progress. [Randy Terbush]
10575 *) Further enhance aplog_error() to not log filename, line number, and
10576 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
10578 *) WIN32: Canonicalise filenames under Win32. Short filenames are
10579 converted to long ones. Backslashes are converted to forward
10580 slashes. Case is converted to lower. Parts of URLs that do not
10581 correspond to files are left completely alone. [Ben Laurie]
10583 *) PORT: 2 new OSs added to the list of ports:
10584 Encore's UMAX V: Arieh Markel <amarkel encore.com>
10585 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
10587 *) Add the server version (SERVER_VERSION macro) to the "server
10588 configured and running" entry in the error_log. Also build an
10589 object file at link-time that contains the current time
10590 (SERVER_BUILT global const char[]), and include that in the
10591 message. [Ken Coar]
10593 *) Set r->headers_out when sending responses from the proxy.
10594 This fixes things such as the logging of headers sent from
10595 the proxy. [Marc Slemko] PR#659
10597 *) support/httpd_monitor is no longer distributed because the
10598 scoreboard should not be file based if at all possible. Use
10599 mod_status to see current server snapshot.
10601 *) (set_file_slot): New function, allowing auth directives to be
10602 independent of the server root, so the server documents can be
10603 moved to a different directory or machine more easily.
10604 [David J. MacKenzie]
10606 *) If no TransferLog is given explicitly, decline
10607 to log. This supports coexistence with other logging modules,
10608 such as the custom one that UUNET uses. [David J. MacKenzie]
10610 *) Check for titles in server-parsed HTML files.
10611 Ignore leading newlines and returns in titles. The old behavior
10612 of replacing a newline after <title> with a space causes the
10613 title to be misaligned in the listing. [David J. MacKenzie]
10615 *) Change mod_cern_meta to be configurable on a per-directory basis.
10616 [David J. MacKenzie]
10618 *) Add 'Include' directive to allow inclusion of configuration
10619 files within configuration files. [Randy Terbush]
10621 *) Proxy errors on connect() are logged to the error_log (nothing
10622 new); now they include the IP address and port that failed
10623 (*that's* new). [Ken Coar, Marc Slemko] PR#352
10625 *) Various architectures now define USE_MMAP_FILES which causes
10626 the server to use mmap() for static files. There are two
10627 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
10628 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
10629 number of bytes written in one cycle from a single mmap()d object,
10630 default 32768). [Dean Gaudet]
10632 *) API: Added post_read_request API phase which is run right after reading
10633 the request from a client, or right after an internal redirect. It is
10634 useful for modules setting environment variables that depend only on
10635 the headers/contents of the request. It does not run during subrequests
10636 because subrequests inherit pretty much everything from the main
10637 request. [Dean Gaudet]
10639 *) Added mod_unique_id which is used to generate a unique identifier for
10640 each hit, available in the environment variable UNIQUE_ID.
10643 *) init_modules is now called after the error logs have been opened. This
10644 allows modules to emit information messages into the error logs.
10647 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10648 information for case where proxy module is not available. [Marc Slemko]
10650 *) PORT: Apache has need for mutexes to serialize its children around
10651 accept. In prior versions either fcntl file locking or flock file
10652 locking were used. The method is chosen by the definition of
10653 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
10654 and FLOCK for flock(). New options have been added:
10655 - SYSVSEM to use System V style semaphores
10656 - PTHREAD to use POSIX threads (appears to work on Solaris only)
10657 - USLOCK to use IRIX uslock
10658 Based on timing various techniques, the following changes were made
10660 - Linux 2.x uses flock instead of fcntl
10661 - Solaris 2.x uses pthreads
10662 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
10663 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
10664 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
10665 Martijn Koster <m.koster pobox.com>]
10667 *) PORT: The semantics of accept/select make it very desirable to use
10668 mutexes to serialize accept when multiple Listens are in use. But
10669 in the case where only a single socket is open it is sometimes
10670 redundant to serialize accept(). Not all unixes do a good job with
10671 potentially dozens of children blocked on accept() on the same
10672 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
10673 the server will avoid serialization when listening on only one socket,
10674 and use serialization when listening on multiple sockets.
10675 [Dean Gaudet] PR#467
10677 *) Configure changes: TestLib replaced by TestCompile, which has
10678 some additional capability (such as doing a sanity check of
10679 the compiler and flags selected); the version of Solaris is now
10680 available via the #define value of SOLARIS2; IRIX n32bit libs
10681 now supported and selectable by new Configuration Rule: IRIXN32;
10682 We no longer default to -O2 optimization. [Jim Jagielski]
10684 *) Updated Configure: Configuration now uses AddModule to specify
10685 module source or binary file location, relative to src directory.
10686 Modules can be dropped into modules/extra, or in their own
10687 directory, and modules can come with a Makefile or Configure can
10688 create one. Modules can add compiler or library information to
10689 generated Makefiles. [Paul Sutton]
10691 *) Source core re-organisation: distributed modules are now in
10692 modules/standard. All other source code is in main. OS-specific
10693 code is in os/{unix,emx,win32} directories. [Paul Sutton]
10695 *) mod_browser has been removed, since it's replaced by mod_setenvif.
10698 *) Fix another long-standing bug in sub_req_lookup_file where it would
10699 happily skip past access checks on subdirectories looked up with
10700 relative paths. (It's used by mod_dir, mod_negotiation,
10701 and mod_include.) [Dean Gaudet]
10703 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
10704 N is the number of <Directory> sections, and M is the number of
10705 components in the filename of an object.
10707 To achieve this optimization the following config changes were made:
10708 - Wildcards (* and ?, not the regex forms) in <Directory>s,
10709 <Files>s, and <Location>s now treat a slash as a special
10710 character. For example "/home/*/public_html" previously would
10711 match "/home/a/andrew/public_html", now it only matches things
10712 like "/home/bob/public_html". This mimics /bin/sh behaviour.
10713 - It's possible now to use [] wildcarding in <Directory>, <Files>
10715 - Regex <Directory>s are applied after all non-regex <Directory>s.
10719 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
10720 and corrupted paths. [Dean Gaudet]
10722 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
10723 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
10724 be accessed now via backreferences $1..$9 in RewriteConds test-against
10725 strings in addition to RewriteRules subst string. Second the grouped
10726 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
10727 via backreferences %1..%9 both in following RewriteCond test-against
10728 strings and RewriteRules subst string. This provides maximum flexibility
10729 through the use of backreferences.
10730 Additionally the rewriting engine was cleaned up by putting common
10731 code to the new expand_backrefs_inbuffer() function.
10732 [Ralf S. Engelschall]
10734 *) When merging the main server's <Directory> and <Location> sections into
10735 a vhost, put the main server's first and the vhost's second. Otherwise
10736 the vhost can't override the main server. [Dean Gaudet] PR#717
10738 *) The <Directory> code would merge and re-merge the same section after
10739 a match was found, possibly causing problems with some modules.
10742 *) ip-based vhosts are stored and queried using a hashing function, which
10743 has been shown to improve performance on servers with many ip-vhosts.
10744 Some other changes had to be made to accommodate this:
10745 - the * address for vhosts now behaves like _default_
10746 - the matching process now is:
10747 - match an ip-vhost directly via hash (possibly matches main
10749 - if that fails, just pretend it matched the main server
10750 - if so far only the main server has been matched, perform
10751 name-based lookups (ServerName, ServerAlias, ServerPath)
10752 *only on name-based vhosts*
10753 - if they fail, look for _default_ vhosts
10754 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
10756 *) dbmmanage overhaul:
10757 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
10758 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
10759 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
10760 - provide better seed for rand
10761 - prompt for password as per getpass(3) (turn off echo, read from
10763 - use "newstyle" crypt based on $Config{osname} ($^O)
10764 - will not add a user if already in database, use new `update' command
10766 - added `check' command to check a users' password
10767 - added `import' command to convert existing password text-files or
10768 dbm files exported with `view'
10769 - more descriptive usage, general cleanup, 'use strict' clean, etc.
10772 *) Added psocket() which is a pool form of socket(), various places within
10773 the proxy weren't properly blocking alarms while registering the cleanup
10774 for its sockets. bclose() now uses pclose() and pclosesocket(). There
10775 was a bug where the client socket was being close()d twice due a still
10776 registered cleanup. [Dean Gaudet]
10778 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
10781 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
10782 [Jason Venner <jason idiom.com>] PR#667
10784 *) Enable ``=""'' for RewriteCond directives to match against
10785 the empty string. This is the preferred way instead of ``^$''.
10786 [Ralf S. Engelschall]
10788 *) Fixed an infinite loop in mod_imap for references above the server root
10789 [Dean Gaudet] PR#748
10791 *) mod_proxy now has a ReceiveBufferSize directive, similar to
10792 SendBufferSize, so that the TCP window can be set appropriately
10793 for LFNs. [Phillip A. Prindeville]
10795 *) mod_browser has been replaced by the more general mod_setenvif
10796 (courtesy of Paul Sutton). BrowserMatch* directives are still
10797 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
10798 UnSetEnvIfZero directives. [Ken Coar]
10800 *) "HostnameLookups double" forces double-reverse DNS to succeed in
10801 order for remote_host to be set (for logging, or for the env var
10802 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
10805 *) mod_access overhaul:
10806 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
10807 and cidr syntax (i.e. 10.1.0.0/16). PR#762
10808 - Critical path was sped up by pre-computing a few things at config time.
10809 - The undocumented syntax "allow user-agents" was removed,
10810 the replacement is "allow from env=foobar" combined with mod_browser.
10811 - When used with hostnames it now forces a double-reverse lookup
10812 no matter what the directory settings are. This double-reverse
10813 doesn't affect any of the other routines that use the remote
10814 hostname. In particular it's still passed to CGIs and the log
10815 without the double-reverse check. Related PR#860.
10818 *) When a large bwrite() occurs (larger than the internal buffer size),
10819 while there is already something in the buffer, apache will combine
10820 the large write and the buffer into a single writev(). (This is
10821 in anticipation of using mmap() for reading files.)
10824 *) In obscure cases where a partial socket write occurred while chunking,
10825 Apache would omit the chunk header/footer on the next block. Cleaned
10826 up other bugs/inconsistencies in error conditions in buff.c. Fixed
10827 a bug where a long pause in DNS lookups could cause the last packet
10828 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
10830 *) API: Added child_exit function to module structure. This is called
10831 once per "heavy-weight process" just before a server child exit()'s
10832 e.g. when max_requests_per_child is reached, etc.
10833 [Doug MacEachern, Dean Gaudet]
10835 *) mod_include cleanup showed that handle_else was being used to handle
10836 endif. It didn't cause problems, but it was cleaned up too.
10839 *) mod_cern_meta would attempt to find meta files for the directory itself
10840 in some cases, but not in others. It now avoids it in all cases.
10843 *) mod_mime_magic would core dump if there was a decompression error.
10844 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
10846 *) PORT: some variants of DGUX require -lsocket -lnsl
10847 [Alexander L Jones <alex systems-options.co.uk>] PR#732
10849 *) mod_autoindex now allows sorting of FancyIndexed directory listings
10850 by the various fields (name, size, et cetera), either in ascending
10851 or descending order. Just click on the column header. [Ken Coar]
10853 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
10854 CPUs like the Alpha. Apache still stores ints in pointers, but that's
10855 the relatively safe direction. [Dean Gaudet] PR#344
10857 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
10858 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
10860 *) child_main avoids an unneeded call to select() when there is only one
10861 listening socket. [Dean Gaudet]
10863 *) In the event that the server is starved for idle servers it will
10864 spawn 1, then 2, then 4, ..., then 32 servers each second,
10865 doubling each second. It'll also give a warning in the errorlog
10866 since the most common reason for this is a poor StartServers
10867 setting. The define MAX_SPAWN_RATE can be used to raise/lower
10868 the maximum. [Dean Gaudet]
10870 *) Apache now provides an effectively unbuffered connection for
10871 CGI scripts. This means that data will be sent to the client
10872 as soon as the CGI pauses or stops output; previously, Apache would
10873 buffer the output up to a fixed buffer size before sending, which
10874 could result in the user viewing an empty page until the CGI finished
10875 or output a complete buffer. It is no longer necessary to use an
10876 "nph-" CGI to get unbuffered output. Given that most CGIs are written
10877 in a language that by default does buffering (e.g. perl) this
10878 shouldn't have a detrimental effect on performance.
10880 "nph-" CGIs, which formerly provided a direct socket to the client
10881 without any server post-processing, were not fully compatible with
10882 HTTP/1.1 or SSL support. As such they would have had to implement
10883 the transport details, such as encryption or chunking, in order
10884 to work properly in certain situations. Now, the only difference
10885 between nph and non-nph scripts is "non-parsed headers".
10886 [Dean Gaudet, Sameer Parekh, Roy Fielding]
10888 *) If a BUFF is switched from buffered to unbuffered reading the first
10889 bread() will return whatever remained in the buffer prior to the
10890 switch. [Dean Gaudet]
10892 Changes with Apache 1.3a1
10894 *) Added another Configure helper script: TestLib. It determines
10895 if a specified library exists. [Jim Jagielski]
10897 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
10898 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
10901 *) PORT: Some architectures use size_t for various lengths in network
10902 functions such as accept(), and getsockname(). The definition
10903 NET_SIZE_T is used to control this. [Dean Gaudet]
10905 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
10906 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
10907 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
10909 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
10910 [Igor N Kovalenko <infoh mail.wplus.net>]
10912 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
10913 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
10914 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
10915 [Dean Gaudet] related PR#875
10917 *) API: Correct child_init() slot declaration from int to void, to
10918 match the init() declaration. Update mod_example to use the new
10921 *) added transport handle slot (t_handle) to the BUFF structure
10924 *) get_client_block() returns wrong length if policy is
10925 REQUEST_CHUNKED_DECHUNK.
10926 [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#815
10928 *) Support the image map format of FrontPage. For example:
10929 rect /url.hrm 10 20 30 40
10930 ["Chris O'Byrne" <obyrne iol.ie>] PR#807
10932 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
10933 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
10935 *) AddModuleInfo directive for mod_info which allows you to annotate
10936 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
10938 *) Added NoProxy directive to avoid using ProxyRemote for selected
10939 addresses. Added ProxyDomain directive to cause unqualified
10940 names to be qualified by redirection.
10941 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
10943 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
10944 header to the remote host in the proxy. [Sameer Parekh and
10947 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
10948 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
10949 URLs, fixed rewritelog(), fixed forced response code handling on
10950 redirects from within .htaccess files, disabled pipe locking under
10951 braindead SunOS 4.1.x, allow env variables to be set even on rules with
10952 no substitution, bugfixed situations where HostnameLookups is off, made
10953 mod_rewrite more thread-safe for NT port and fixed problem when creating
10954 an empty query string via "xxx?".
10955 This update also removes the copyright of Ralf S. Engelschall,
10956 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
10957 exclusively copyrighted by the Apache Group now. This happened because
10958 the author now has gifted mod_rewrite exclusively to the Apache Group and
10959 no longer maintains an external version.
10960 [Ralf S. Engelschall]
10962 *) API: Added child_init function to module structure. This is called
10963 once per "heavy-weight process" before any requests are handled.
10964 See http_config.h for more details. [Dean Gaudet]
10966 *) Anonymous_LogEmail was logging on each subrequest.
10967 [Dean Gaudet] PR#421, 868
10969 *) API: Added is_initial_req() which tests if the request being
10970 processed is the initial request, or a subrequest.
10973 *) Extended SSI (mod_include) now handles additional relops for
10974 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
10976 *) Configure fixed to correctly propagate user-selected options and
10977 settings (such as CC and OPTIM) to Makefiles other than
10978 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
10980 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
10981 directory indices to start with the contents of the HeaderName file
10982 if there is one. If there isn't one, the behaviour is unchanged.
10983 [Ken Coar, Roy Fielding, Andrey A. Chernov]
10985 *) WIN32: Modules can now be dynamically loaded DLLs using the
10986 LoadModule/LoadFile directives. Note that module DLLs must be
10987 compiled with the multithreaded DLL version of the runtime library.
10988 [Alexei Kosut and Ben Laurie]
10990 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
10991 This allows the admin to completely remove automatic indexing
10992 from the server, while still supporting the basic functions of
10993 trailing-slash redirects and DirectoryIndex files. Note that if
10994 you're carrying over an old Configuration file and you use directory
10995 indexing then you'll want to add:
10997 Module autoindex_module mod_autoindex.o
10999 before mod_dir in your Configuration. [Dean Gaudet]
11001 *) popendir/pclosedir created to properly protect directory scanning.
11002 [Dean Gaudet] PR#525
11004 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
11005 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
11006 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
11009 *) The AccessFileName directive can now take more than one filename.
11010 ["Lou D. Langholtz" <ldl usi.utah.edu>]
11012 *) The new mod_mime_magic can be used to "magically" determine the type
11013 of a file if the extension is unknown. Based on the unix file(1)
11014 command. [Ian Kluft <ikluft cisco.com>]
11016 *) We now determine and display the time spent processing a
11017 request if desired. [Jim Jagielski]
11019 *) mod_status: PID field of "dead" child slots no longer displays
11020 main httpd process's PID. [Jim Jagielski]
11022 *) Makefile.nt added - to build all the bits from the command line:
11023 nmake -f Makefile.nt
11024 Doesn't yet work properly. [Ben Laurie]
11026 *) Default text of 404 error is now "Not Found" rather than the
11027 potentially misleading "File Not Found". [Ken Coar]
11029 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
11030 for the net if we require people that actually need this data to
11031 enable it. [Linus Torvalds]
11033 *) directory_walk() is an expensive function, keep a little more state to
11034 avoid needless string counting. Add two new functions make_dirstr_parent
11035 and make_dirstr_prefix which replace all existing uses of make_dirstr.
11036 The new functions are a little less general than make_dirstr, but
11037 work more efficiently (less memory, less string counting).
11040 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
11041 to LDFLAGS) to avoid complications with lex rules in make files.
11042 [Dean Gaudet] PR#372
11044 *) run_method optimized to avoid needless scanning over NULLs in the
11045 module list. [Dean Gaudet]
11047 *) Revamp of (unix) scoreboard management code such that it avoids
11048 unnecessary traversals of the scoreboard on each hit. This is
11049 particularly important for high volume sites with a large
11050 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
11051 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
11052 httpd.h. [Dean Gaudet]
11054 *) In configurations using multiple Listen statements it was possible for
11055 busy sockets to starve other sockets of service. [Dean Gaudet]
11057 *) Added hook so standalone_main can be replaced at compile time
11058 (define STANDALONE_MAIN)
11061 *) Lowest-level read/write functions in buff.c will be replaced with
11062 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
11063 compile time. The default sfio discipline will behave as apache
11064 would without sfio compiled in.
11067 *) Enhance UserDir directive (mod_userdir) to accept a list of
11068 usernames for the 'disable' keyword, and add 'enable user...' to
11069 selectively *en*able userdirs if they're globally disabled.
11072 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
11073 will work with Netscape dbm files. (dbmmanage will probably not
11074 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
11076 *) Add a ListenBacklog directive to control the backlog parameter
11077 passed to listen(). Also change the default to 511 from 512.
11080 *) API: A new handler response DONE which informs apache that the
11081 request has been handled and it can finish off quickly, similar to
11082 how it handles errors. [Rob Hartill]
11084 *) Turn off chunked encoding after sending terminating chunk/footer
11085 so that we can't do it twice by accident. [Roy Fielding]
11087 *) mod_expire also issues Cache-Control: max-age headers.
11090 *) API: Added kill_only_once option for free_proc_chain so that it won't
11091 aggressively try to kill off specific children. For fastcgi.
11092 [Stanley Gambarin <gambarin OpenMarket.com>]
11094 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
11096 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
11097 When used together, these cause mod_dir to emit HEIGHT and WIDTH
11098 attributes in the FancyIndexing IMG tags. [Ken Coar]
11100 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
11102 *) PORT: Added Windows NT support
11103 [Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
11105 Changes with Apache 1.2.6
11107 *) mod_include when using XBitHack Full would send ETags in addition to
11108 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
11109 [Dean Gaudet] PR#1133
11111 *) SECURITY: When a client connects to a particular port/addr, and
11112 gives a Host: header ensure that the virtual host requested can
11113 actually be reached via that port/addr. [Ed Korthof <ed organic.com>]
11115 *) Support virtual hosts with wildcard port and/or multiple ports
11116 properly. [Ed Korthof <ed organic.com>]
11118 *) Fixed some case-sensitivity issues according to RFC2068.
11121 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
11122 and mod_include.c. [Dean Gaudet]
11124 *) Variable 'cwd' was being used pointlessly before being set.
11127 *) SIGURG doesn't exist on all platforms.
11128 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
11130 *) When an error occurs during a POST, or other operation with a
11131 request body, the body has to be read from the net before allowing
11132 a keepalive session to continue. [Roy Fielding] PR#1399
11134 *) When an error occurs in fcntl() locking suggest the user look up
11135 the docs for LockFile. [Dean Gaudet]
11137 *) table_set() and table_unset() did not deal correctly with
11138 multiple occurrences of the same key. [Stephen Scheck
11139 <sscheck infonex.net>, Ben Laurie] PR#1604
11141 *) send_fd_length() did not calculate total_bytes_sent properly in error
11142 cases. [Ben Reser <breser regnow.com>] PR#1366
11144 *) r->connection->user was allocated in the wrong pool causing corruption
11145 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
11147 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
11148 Also removed the auto-generated link to www.apache.org that was the
11149 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
11151 *) Multiple "close" tokens may have been set in the "Connection"
11152 header, not an error, but a waste.
11153 [<Ronald.Tschalaer psi.ch>] PR#1683
11155 *) "basic" and "digest" auth tokens should be tested case-insensitive.
11156 [<Ronald.Tschalaer psi.ch>] PR#1599, PR#1666
11158 *) It appears the "257th byte" bug (see
11159 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
11160 at the 256th byte as well. Fixed. [Dean Gaudet]
11162 *) mod_rewrite would not handle %3f properly in some situations.
11165 *) Apache could generate improperly chunked HTTP/1.1 responses when
11166 the bputc() or rputc() functions were used by modules (such as
11167 mod_include). [Dean Gaudet]
11169 *) #ifdef wrap a few #defines in httpd.h to make life easier on
11170 some ports. [Ralf Engelschall]
11172 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
11174 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
11176 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
11178 Changes with Apache 1.2.5
11180 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
11181 only an issue on systems without a MAXDNAME define or where
11182 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
11184 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
11187 *) Fix core dump in the ftp proxy when reading incorrectly formatted
11188 directory listings. [Marc Slemko]
11190 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
11193 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
11194 is used to read various types of files such as htaccess and
11195 htpasswd files. [Marc Slemko]
11197 *) SECURITY: Ensure that the buffer returned by ht_time is always
11198 properly null terminated. [Marc Slemko]
11200 *) SECURITY: General mod_include cleanup, including fixing several
11201 possible buffer overflows and a possible infinite loop. This cleanup
11202 was done against 1.3 code and then backported to 1.2, the result
11203 is a large difference (due to indentation cleanup in 1.3 code).
11204 Users interested in seeing a smaller set of relevant differences
11205 should consider comparing against src/modules/standard/mod_include.c
11206 from the 1.3b3 release. Non-indentation changes to mod_include
11207 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
11209 *) SECURITY: Numerous changes to mod_imap in a general cleanup
11210 including fixing a possible buffer overflow. This cleanup also
11211 was done with 1.3 code as a basis, see the the previous note
11212 about mod_include. [Dean Gaudet]
11214 *) SECURITY: If a htaccess file can not be read due to bad
11215 permissions, deny access to the directory with a HTTP_FORBIDDEN.
11216 The previous behavior was to ignore the htaccess file if it could not
11217 be read. This change may make some setups with unreadable
11218 htaccess files stop working. PR#817 [Marc Slemko]
11220 *) SECURITY: no2slash() was O(n^2) in the length of the input.
11221 Make it O(n). This inefficiency could be used to mount a denial
11222 of service attack against the Apache server. Thanks to
11223 Michal Zalewski <lcamtuf boss.staszic.waw.pl> for reporting
11224 this. [Dean Gaudet]
11226 *) mod_include used uninitialized data for some uses of && and ||.
11227 [Brian Slesinsky <bslesins wired.com>] PR#1139
11229 *) mod_imap should decline all non-GET methods.
11230 [Jay Bloodworth <jay pathways.sde.state.sc.us>]
11232 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
11234 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
11235 r->filename. Since those two are meant to be in sync with each other
11236 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
11238 *) mod_include did not properly handle all possible redirects from sub-
11239 requests. [Ken Coar]
11241 *) Inetd mode (which is buggy) uses timeouts without having setup the
11242 jmpbuffer. [Dean Gaudet] PR#1064
11244 *) Work around problem under Linux where a child will start looping
11245 reporting a select error over and over.
11246 [Rick Franchuk <rickf transpect.net>] PR#1107
11248 Changes with Apache 1.2.4
11250 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
11251 always making requests with the full-URI instead of just the URI path.
11252 [Marc Slemko, Roy Fielding]
11254 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
11255 on this platform. [Marc Slemko]
11257 Changes with Apache 1.2.3
11259 *) The request to a remote proxy was mangled if it was generated as the
11260 result of a ProxyPass directive. URL schemes other than http:// were not
11261 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
11262 PR#812 [Lars Eilebrecht]
11264 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11265 information for case where proxy module is not available. [Marc Slemko]
11267 *) Force proxy to always respond as HTTP/1.0, which it was failing to
11268 do for errors and cached responses. [Roy Fielding]
11270 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
11272 Changes with Apache 1.2.2 [not released]
11274 *) Fixed another long-standing bug in sub_req_lookup_file where it would
11275 happily skip past access checks on subdirectories looked up with relative
11276 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
11279 *) Add lockfile name to error message printed out when
11280 USE_FLOCK_SERIALIZED_ACCEPT is defined.
11283 *) Enhanced the chunking and error handling inside the buffer functions.
11284 [Dean Gaudet, Roy Fielding]
11286 *) When merging the main server's <Directory> and <Location> sections into
11287 a vhost, put the main server's first and the vhost's second. Otherwise
11288 the vhost can't override the main server. [Dean Gaudet] PR#717
11290 *) The <Directory> code would merge and re-merge the same section after
11291 a match was found, possibly causing problems with some modules.
11294 *) Fixed an infinite loop in mod_imap for references above the server root.
11295 [Dean Gaudet] PR#748
11297 *) mod_include cleanup showed that handle_else was being used to handle
11298 endif. It didn't cause problems, but it was cleaned up too.
11301 *) Last official synchronization of mod_rewrite with author version (because
11302 mod_rewrite is now directly developed by the author at the Apache Group):
11303 o added diff between mod_rewrite 3.0.6+ and 3.0.9
11304 minus WIN32/NT stuff, but plus copyright removement.
11306 - workaround for detecting infinite rewriting loops
11307 - fixed setting of env vars when "-" is used as subst string
11308 - fixed forced response code on redirects (PR#777)
11309 - fixed cases where r->args is ""
11310 - kludge to disable locking on pipes under braindead SunOS
11311 - fix for rewritelog in cases where remote hostname is unknown
11312 - fixed totally damaged request_rec walk-back loop
11313 o remove static from local data and add static to global ones.
11314 o replaced ugly proxy finding stuff by simple
11315 find_linked_module("mod_proxy") call.
11316 o added missing negation char on rewritelog()
11317 o fixed a few comment typos
11318 [Ralf S. Engelschall]
11320 *) Anonymous_LogEmail was logging on each subrequest.
11321 [Dean Gaudet] PR#421, PR#868
11323 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11324 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11325 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11326 Additionally mod_browser now triggers during translate_name to workaround
11327 a deficiency in the header_parse phase.

11335 [Marc Slemko] PR#848
11337 *) The proxy didn't treat the "Host:" keyword of the host header as case-
11338 insensitive. The proxy would corrupt the first line of a response from
11339 an HTTP/0.9 server. [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#813,814
11341 *) mod_include would log some bogus values occasionally.

11344 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
11345 under Solaris 2.x (up through 2.5.1). It has been fixed.
11346 [Dean Gaudet] PR#832
11348 *) API: In HTTP/1.1, whether or not a request message contains a body
11349 is independent of the request method and based solely on the presence
11350 of a Content-Length or Transfer-Encoding. Therefore, our default
11351 handlers need to be prepared to read a body even if they don't know
11352 what to do with it; otherwise, the body would be mistaken for the
11353 next request on a persistent connection. discard_request_body()
11354 has been added to take care of that. [Roy Fielding] PR#378
11356 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
11357 release version number, such that it always increases along the
11358 same lines as our source code branching. [Roy Fielding]
11360 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
11362 Changes with Apache 1.2.1
11364 *) SECURITY: Don't serve file system objects unless they are plain files,
11365 symlinks, or directories. This prevents local users from using pipes
11366 or named sockets to invoke programs for an extremely crude form of
11369 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
11370 could contain "../" allowing a local user to "publish" any file on
11371 the system. No slashes are allowed now. [Dean Gaudet]
11373 *) SECURITY: It was possible to violate the symlink Options using mod_dir
11374 (headers, readmes, titles), mod_negotiation (type maps), or
11375 mod_cern_meta (meta files). [Dean Gaudet]
11377 *) SECURITY: Apache will refuse to run as "User root" unless
11378 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
11380 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
11381 if it contained a .htaccess disallowing symlinks. This is contrary
11382 to the rule that symlink permissions are tested with the symlink
11383 options of the parent directory. [Dean Gaudet] PR#353
11385 *) CONFIG: The LockFile directive can be used to place the serializing
11386 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
11387 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
11390 *) Request processing now retains state of whether or not the request
11391 body has been read, so that internal redirects and subrequests will
11392 not try to read it twice (and block). [Roy Fielding]
11394 *) Add a placeholder in modules/Makefile to avoid errors with certain
11395 makes. [Marc Slemko]
11397 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
11398 [Dean Gaudet] PR#644
11400 *) mod_include was not properly changing the current directory.
11401 [Marc Slemko] PR#742
11403 *) Attempt to work around problems with third party libraries that do not
11404 handle high numbered descriptors (examples include bind, and
11405 solaris libc). On all systems apache attempts to keep all permanent
11406 descriptors above 15 (called the low slack line). Solaris users
11407 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
11408 which keeps all non-FILE * descriptors above 255. On all systems
11409 this should make supporting large numbers of vhosts with many open
11410 log files more feasible. If this causes trouble please report it,
11411 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
11412 [Dean Gaudet] various PRs
11414 *) Related to the last entry, network sockets are now opened before
11415 log files are opened. The only known case where this can cause
11416 problems is under Solaris with many virtualhosts and many Listen
11417 directives. But using -DHIGH_SLACK_LINE=256 described above will
11418 work around this problem. [Dean Gaudet]
11420 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
11423 *) Improved unix error response logging. [Marc Slemko]
11425 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
11426 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
11427 when a URL http://... was used in conjunction with a special
11428 redirect flag, e.g. R=permanent, the permanent status was lost.
11429 [Ronald Tschalaer <Ronald.Tschalaer psi.ch>, Ralf S. Engelschall]

11465 Changes with Apache 1.2b11
11467 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
11469 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
11470 [Doug MacEachern, Rob Hartill]
11472 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
11473 reading from one buffer and writing to another, at least until it has
11474 a custom timeout handler. [Roy Fielding and Petr Lampa]
11476 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
11477 apparently due to a mismatch between sigaction and setjmp.
11478 [Roy Fielding] PR#502
11480 *) Log correct status code if we timeout before receiving a request (408)
11481 or if we received a request-line that was too long to process (414).

11484 *) Virtual hosts with the same ServerName, but on different ports, were
11485 not being selected properly. [Ed Korthof]
11487 *) Added code to return the requested IP address from proxy_host2addr()
11488 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
11489 change submitted by Jozsef Hollosi <hollosi sbcm.com>.
11490 [Chuck Murcko] PR#614
11492 *) If multiple requests on a single connection are used to retrieve
11493 data from different virtual hosts, the virtual host list would be
11494 scanned starting with the most recently used VH instead of the first,
11495 causing most virtual hosts to be ignored.
11496 [Paul Sutton and Martin Mares] PR#610
11498 *) The OS/2 handling of process group was broken by a porting patch for
11499 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
11501 *) Inherit virtual server port from main server if none (or "*") is
11502 given for VirtualHost. [Dean Gaudet] PR#576
11504 *) If the lookup for a DirectoryIndex name with content negotiation
11505 has found matching variants, but none are acceptable, return the
11506 negotiation result if there are no more DirectoryIndex names to lookup.
11507 [Petr Lampa and Roy Fielding]
11509 *) If a soft_timeout occurs after keepalive is set, then the main child
11510 loop would try to read another request even though the connection
11511 has been aborted. [Roy Fielding]
11513 *) Configure changes: Allow for whitespace at the start of a
11514 Module declaration. Also, be more understanding about the
11515 CC=/OPTIM= format in Configuration. Finally, fix compiler
11516 flags if using HP-UX's cc compiler. [Jim Jagielski]
11518 *) Subrequests and internal redirects now inherit the_request from the
11519 original request-line. [Roy Fielding]
11521 *) Test for error conditions before creating output header fields, since
11522 we don't want the error message to include those fields. Likewise,
11523 reset the content_language(s) and content_encoding of the response
11524 before generating or redirecting to an error message, since the new
11525 message will have its own Content-* definitions. [Dean Gaudet]
11527 *) Restored the semantics of headers_out (headers sent only with 200..299
11528 and 304 responses) and err_headers_out (headers sent with all responses).
11529 Avoid the overhead of copying tables if err_headers_out is empty
11530 (the usual case). [Roy Fielding]
11532 *) Fixed a couple places where a check for the default Content-Type was
11533 not properly checking both the value configured by the DefaultType
11534 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
11535 of DEFAULT_TYPE to match the documented default (text/plain).
11536 [Dean Gaudet] PR#506
11538 *) Escape the HTML-sensitive characters in the Request-URI that is
11539 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
11541 *) Properly initialize the flock structures used by the mutex locking
11542 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
11545 *) The method for determining PATH_INFO has been restored to the pre-1.2b
11546 (and NCSA httpd) definition wherein it was the extra path info beyond
11547 the CGI script filename. The environment variable FILEPATH_INFO has
11548 been removed, and instead we supply the original REQUEST_URI to any
11549 script that wants to be Apache-specific and needs the real URI path.
11550 This solves a problem with existing scripts that use extra path info
11551 in the ScriptAlias directive to pass options to the CGI script.
11554 *) The _default_ change in 1.2b10 will change the behaviour on configs
11555 that use multiple Listen statements for listening on multiple ports.
11556 But that change is necessary to make _default_ consistent with other
11557 forms of <VirtualHost>. It requires such configs to be modified
11558 to use <VirtualHost _default_:*>. The documentation has been
11559 updated. [Dean Gaudet] PR#530
11561 *) If an ErrorDocument CGI script is used to respond to an error
11562 generated by another CGI script which has already read the message
11563 body of the request, the server would block trying to read the
11564 message body again. [Rob Hartill]
11566 *) signal() replacement conflicted with a define on QNX (and potentially
11567 other platforms). Fixed. [Ben Laurie] PR#512
11569 Changes with Apache 1.2b10
11571 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
11572 to be configured via -D in Configuration. [Dean Gaudet] PR#449
11574 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
11576 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
11578 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
11579 config, in case the hostent struct returned is trash.
11580 [Chuck Murcko] PR #491
11582 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
11583 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
11585 Changes with Apache 1.2b9 [never announced]
11587 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
11588 changes and in anticipation of 1.2 final release. [Roy Fielding]
11590 *) Fix problem with scripts not receiving a SIGPIPE when client drops
11591 the connection (e.g., when user presses Stop). Apache will now stop
11592 trying to send a message body immediately after an error from write.
11593 [Roy Fielding and Nathan Kurz] PR#335
11595 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
11596 than mod_alias, and mod_alias has higher priority than mod_proxy;
11597 rearranged other modules to enhance understanding of their purpose
11598 and relative order (and maybe even reduce some overhead).
11599 [Roy Fielding and Sameer Parekh]
11601 *) Fix graceful restart. Eliminate many signal-related race
11602 conditions in both forms of restart, and in SIGTERM. See
11603 htdocs/manual/stopping.html for details on stopping and
11604 restarting the parent. [Dean Gaudet]
11606 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
11607 memory allocator to avoid a behaviour that required extra blocks to
11608 be allocated. [Dean Gaudet]
11610 *) Allow suexec to access files relative to current directory but not
11611 above. (Excluding leading / or any .. directory.) [Ken Coar]

11615 PR#367, 368, 354, 453
11617 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
11618 while obtaining the /~user and save the username in a separate data
11619 area so that it won't be overwritten by the call to getgrgid(), and
11620 fix some misuse of the pool string allocation functions. Also fixes
11621 a general problem with parsing URL query info into args for CGI scripts.

11629 AuthDBAuthoritative. [Marc Slemko] PR#420
11631 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
11633 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
11634 object that can't be PUT, or FOOBAR for some method FOOBAR that
11635 apache doesn't know about at all). Log 404s that occur in mod_include.
11636 [Paul Sutton, John Van Essen]
11638 *) If a soft timeout (or lingerout) occurs while trying to flush a
11639 buffer or write inside buff.c or fread'ing from a CGI's output,
11640 then the timeout would be ignored. [Roy Fielding] PR#373
11642 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
11643 parsing of headers. If the terminating empty-line CRLF occurs starting
11644 at the 256th or 257th byte of output, then Navigator will think a normal
11645 image is invalid. We are guessing that this is because their initial
11646 read of a new request uses a 256 byte buffer. We check the bytes written
11647 so far and, if we are about to tickle the bug, we instead insert a
11648 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
11650 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
11651 of an external redirection. [Roy Fielding and Paul Sutton]
11653 *) Configure would create a broken Makefile if the configuration file
11654 contained a commented-out Rule. [Roy Fielding]
11656 *) Promote per_dir_config and subprocess_env from the subrequest to the
11657 main request in mod_negotiation. In particular this fixes a bug
11658 where <Files> sections wouldn't properly apply to negotiated content.
11661 *) Fix a potential deadlock in mod_cgi script_err handling.

11664 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
11665 [Mitchell Blank Jr]
11667 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
11668 .htaccess files because the RewriteBase was not replaced correctly.
11669 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
11670 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
11672 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
11673 1.x the settings are those of pre-1.2b8. For 2.x we include
11674 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
11675 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
11676 [Dean Gaudet] PR#336, PR#340
11678 *) Redirect did not preserve ?query_strings when present in the client's

11691 *) Improve handling of directories when filenames have spaces in them.
11694 *) For hosts with multiple IP addresses, try all additional addresses if
11695 necessary to get a connect. Fail only if hostent address list is
11696 exhausted. [Chuck Murcko]
11698 *) More signed/unsigned port fixes. [Dean Gaudet]
11700 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
11703 Changes with Apache 1.2b8
11705 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
11706 to it. [Marc Slemko]
11708 *) The addition of <Location> and <File> directives made the
11709 sub_req_lookup_simple() function bogus, so we now handle
11710 the special cases directly. [Dean Gaudet]
11712 *) We now try to log where the server is dumping core when a fatal
11713 signal is received. [Ken Coar]
11715 *) Improved lingering_close by adding a special timeout, removing the
11716 spurious log messages, removing the nonblocking settings (they
11717 are not needed with the better timeout), and adding commentary
11718 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
11719 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
11721 *) Send error messages about setsockopt failures to the server error
11722 log instead of stderr. [Roy Fielding]
11724 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
11726 *) Stopgap solution for CGI 3-second delay with server-side includes: if
11727 processing a subrequest, allocate memory from r->main->pool instead
11728 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
11729 in the middle of an SSI request. [Dean Gaudet] PR #122
11731 *) Fixed status of response when POST is received for a nonexistent URL
11732 (was sending 405, now 404) and when any method is sent with a
11733 full-URI that doesn't match the server and the server is not acting
11734 as a proxy (was sending 501, now 403). [Roy Fielding]
11736 *) Host port changed to unsigned short. [Ken Coar] PR #276
11738 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
11740 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
11742 *) Report extra info from errno with many errors that cause httpd to exit.
11743 spawn_child, popenf, and pclosef now have valid errno returns in the
11744 event of an error. Correct problems where errno was stomped on
11745 before being reported. [Dean Gaudet]
11747 *) In the proxy, if the cache filesystem was full, garbage_coll() was
11748 never called, and thus the filesystem would remain full indefinitely.
11749 We now also remove incomplete cache files left if the origin server
11750 didn't send a Content-Length header and either the client has aborted
11751 transfer or bwrite() to client has failed. [Petr Lampa]
11753 *) Fixed the handling of module and script-added header fields.
11754 Improved the interface for sending header fields and reduced
11755 the duplication of code between sending okay responses and errors.
11756 We now always send both headers_out and err_headers_out, and
11757 ensure that the server-reserved fields are not being overridden,
11758 while not overriding those that are not reserved. [Roy Fielding]
11760 *) Moved transparent content negotiation fields to err_headers_out
11761 to reflect above changes. [Petr Lampa]
11763 *) Fixed the determination of whether or not we should make the
11764 connection persistent for all of the cases where some other part
11765 of the server has already indicated that we should not. Also
11766 improved the ordering of the test so that chunked encoding will
11767 be set whenever it is desired instead of only when KeepAlive
11768 is enabled. Added persistent connection capability for most error
11769 responses (those that do not indicate a bad input stream) when
11770 accessed by an HTTP/1.1 client. [Roy Fielding]
11772 *) Added missing timeouts for sending header fields, error responses,
11773 and the last chunk of chunked encoding, each of which could have
11774 resulted in a process being stuck in write forever. Using soft_timeout
11775 requires that the sender check for an aborted connection rather than
11776 continuing after an EINTR. Timeouts that used to be initiated before
11777 send_http_header (and never killed) are now initiated only within or
11778 around the routines that actually do the sending, and not allowed to
11779 propagate above the caller. [Roy Fielding]
11781 *) mod_auth_anon required an @ or a . in the email address, not both.
11784 *) per_dir_defaults weren't set correctly until directory_walk for
11785 name-based vhosts. This fixes an obscure bug with the wrong config
11786 info being used for vhosts that share the same ip as the server.
11789 *) Improved generation of modules/Makefile to be more generic for
11790 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
11792 *) Generate makefile dependency for Configuration based on the actual
11793 name given when running the Configure process. [Dean Gaudet]
11795 *) Fixed problem with vhost error log not being set prior to
11796 initializing virtual hosts. [Dean Gaudet]
11798 *) Fixed infinite loop when a trailing slash is included after a type map
11799 file URL (extra path info). [Petr Lampa]
11801 *) Fixed server status updating of per-connection counters. [Roy Fielding]
11803 *) Add documentation for DNS issues (reliability and security), and try
11804 to explain the virtual host matching process. [Dean Gaudet]
11806 *) Try to continue gracefully by disabling the vhost if a DNS lookup
11807 fails while parsing the configuration file. [Dean Gaudet]
11809 *) Improved calls to setsockopt. [Roy Fielding]
11811 *) Negotiation changes: Don't output empty content-type in variant list;
11812 Output charset in variant list; Return sooner from handle_multi() if
11813 no variants found; Add handling of '*' wildcard in Accept-Charset.
11814 [Petr Lampa and Paul Sutton]
11816 *) Fixed overlaying of request/sub-request notes and headers in
11817 mod_negotiation. [Dean Gaudet]
11819 *) If two variants' charset quality are equal and one is the default
11820 charset (iso-8859-1), then prefer the variant that was specifically
11821 listed in Accept-Charset instead of the default. [Petr Lampa]
11823 *) Memory allocation problem in push_array() -- it would corrupt memory
11824 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
11826 *) invoke_handler() doesn't handle mime arguments in content-type
11827 [Petr Lampa] PR#160
11829 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
11832 *) Fixed problem with ErrorDocument not working for virtual hosts
11833 due to one of the performance changes in 1.2b7. [Dean Gaudet]
11835 *) Log an error message if we get a request header that is too long,
11836 since it may indicate a buffer overflow attack. [Marc Slemko]
11838 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
11839 not reject URLs without a double-slash, as per RFC2068 section 3.2.
11840 [Ken Coar] PR #146, #187
11842 *) Added table entry placeholder for new header_parser callback
11843 in all of the distributed modules. [Ken Coar] PR #191
11845 *) Allow for cgi files without the .EXE extension on them under OS/2.
11846 [Garey Smiley] PR #59
11848 *) Fixed error message when resource is not found and URL contains
11849 path info. [Petr Lampa and Dean Gaudet] PR #40
11851 *) Fixed user and server confusion over what should be a virtual host
11852 and what is the main server, resulting in access to something
11853 other than the name defined in the virtualhost directive (but
11854 with the same IP address) failing. [Dean Gaudet]
11856 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
11857 AIX; improves the redirection stuff to enable the users to generally
11858 redirect to http, https, gopher and ftp; added TIME variable for
11859 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
11860 special patterns >STRING, <STRING and =STRING to RewriteCond, which
11861 can be used in conjunction with %{TIME} or other variables to create
11862 time-dependent rewriting rules. [Ralf S. Engelschall]
11864 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
11865 Module authors may need to adjust their code for proper cleanup to take
11866 place (that is, call note_cleanups_for_fd()). This change fixes problems
11867 with file descriptors being erroneously closed when the proxy module was
11868 in use. [Ben Laurie]
11870 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
11871 initgroups() to hose the group information needed for later
11872 comparisons. [Randy Terbush]
11874 *) Remove unnecessary call to va_end() in create_argv() which
11875 caused a SEGV on some systems.
11877 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
11880 *) Clear memory allocated for listeners. [Randy Terbush]
11882 *) Improved handling of IP address as a virtualhost address and
11883 introduced "_default_" as a synonym for the default vhost config.
11884 [Dean Gaudet] PR #212
11886 Changes with Apache 1.2b7
11888 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
11890 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
11892 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
11893 - replace protocol response numbers with symbols
11894 - save variant-list into main request notes
11895 - free allocated memory from subrequests
11896 - merge notes, headers_out and err_headers_out
11898 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
11899 "HTTP/#.# ###*" to be more lenient about what we accept.
11902 *) more proxy FTP bug fixes:
11903 - Changed send_dir() to remove user/passwd from displayed URL.
11904 - Changed login error messages to be more descriptive.
11905 - remove setting of SO_DEBUG socket option
11906 - Make ftp_getrc() more lenient about multiline responses,
11907 specifically, 230 responses which don't have continuation 230-
11908 on each line). These seem to be all NT FTP servers, and while
11909 perhaps questionable, they appear to be legal by RFC 959.
11910 - Add missing kill_timeout() after transfer to user completes.
11913 *) Fixed problem where a busy server could hang when restarting
11914 after being sent a SIGHUP due to child processes not exiting.
11917 *) Modify mod_include escaping so a '\' only signifies an escaped
11918 character if the next character is one that needs
11919 escaping. [Ben Laurie]
11921 *) Eliminated possible infinite loop in mod_imap when relative URLs are
11922 used with a 'base' directive that does not have a '/' in it.
11923 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
11925 *) Reduced the default timeout from 1200 seconds to 300, and the
11926 one in the sample configfile from 400 to 300. [Marc Slemko]
11928 *) Stop vbprintf from crashing if given a NULL string pointer;
11929 print (null) instead. [Ken Coar]
11931 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
11932 [Marc Slemko and Roy Fielding]
11934 *) Fixed problem with mod_cgi-generated internal redirects trying to
11935 read the request message-body twice. [Archie Cobbs and Roy Fielding]
11937 *) Reduced timeout on lingering close, removed possibility of a blocked
11938 read causing the child to hang, and stopped logging of errors if
11939 the socket is not connected (reset by client). [Roy Fielding]
11941 *) Rearranged main child loop to remove duplication of code in
11942 select/accept and keep-alive requests, fixed several bugs regarding
11943 checking scoreboard_image for exit indication and failure to
11944 account for all success conditions and trap all error conditions,
11945 prevented multiple flushes before closing the socket; close the entire
11946 socket buffer instead of just one descriptor, prevent logging of
11947 EPROTO and ECONNABORTED on platforms where supported, and generally
11948 improved readability. [Roy Fielding]
11950 *) Extensive performance improvements. Cleaned up inefficient use of
11951 auto initializers, multiple is_matchexp calls on a static string,
11952 and excessive merging of response_code_strings. [Dean Gaudet]
11954 *) Added double-buffering to mod_include to improve performance on
11955 server-side includes. [Marc Slemko]
11957 *) Several fixes for suexec wrapper. [Randy Terbush]
11958 - Make wrapper work for files on NFS filesystem.
11959 - Fix portability problem of MAXPATHLEN.
11960 - Fix array overrun problem in clean_env().
11961 - Fix allocation of PATH environment variable
11963 *) Removed extraneous blank line is description of mod_status chars.
11966 *) Logging of errors from the call_exec routine simply went nowhere,
11967 since the logfile fd has been closed, so now we send them to stderr.
11968 [Harald T. Alvestrand]
11970 *) Fixed core dump when DocumentRoot is a CGI.
11971 [Ben Laurie, reported by <geddis tesserae.com>]
11973 *) Fixed potential file descriptor leak in mod_asis; updated it and
11974 http_core to use pfopen/pfclose instead of fopen/fclose.
11975 [Randy Terbush and Roy Fielding]
11977 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
11978 as the DEC Alpha which is 64-bit but uses 32-bit ints.
11979 [Dean Gaudet and Ken Coar]
11981 *) Return a 302 response code to the client when sending a redirect
11982 due to a missing trailing '/' on a directory instead of a 301; now
11983 it is cacheable. [Markus Gyger]
11985 *) Fix condition where, if a bad directive occurs in .htaccess, and
11986 sub_request() goes first to this directory, then log_reason() will
11987 SIGSEGV because it doesn't have initialized r->per_dir_config.
11988 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
11990 *) Fix handling of lang_index in is_variant_better(). This was
11991 causing problems which resulted in the server sending the
11992 wrong language document in some cases. [Petr Lampa]
11994 *) Remove free() from clean_env() in suexec wrapper. This was nuking
11995 the clean environment on some systems.
11997 *) Tweak byteserving code (e.g. serving PDF files) to work around
11998 bugs in Netscape Navigator and Microsoft Internet Explorer.
11999 Emit Content-Length header when sending multipart/byteranges.
12002 *) Port to HI-UX/WE2. [Nick Maclaren]
12004 *) Port to HP MPE operating system for HP 3000 machines
12005 [Mark Bixby <markb cccd.edu>]
12007 *) Fixed bug which caused a segmentation fault if only one argument
12008 given to RLimit* directives. [Ed Korthof]
12010 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
12012 *) Improved buffered output to the client by delaying the flush decision
12013 until the BUFF code is actually about to read the next request.
12014 This fixes a problem introduced in 1.2b5 with clients that send
12015 an extra CRLF after a POST request. Also improved chunked output
12016 performance by combining writes using writev() and removing as
12017 many bflush() calls as possible. NOTE: Platforms without writev()
12018 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
12019 or Configure, unless we have already done so. [Dean Gaudet]
12021 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
12023 *) Fixed mod_info output corruption bug introduced by buffer overflow
12024 fixes. [Dean Gaudet]
12026 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
12027 for the special case of a 304 response. [Paul Sutton]
12029 *) Improved handling of TRACE method by bypassing normal method handling
12030 and header parsing routines; fixed Allow response to always allow TRACE.
12033 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
12035 *) Cleaned-up some of the generated HTML. [Ken Coar]
12037 Changes with Apache 1.2b6
12039 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
12041 *) Fix typo introduced in fix for potential infinite loop around
12042 accept() in child_main(). This change caused the rev to 1.2b6.
12043 1.2b5 was never a public beta.
12045 Changes with Apache 1.2b5
12047 *) Change KeepAlive semantics (On|Off instead of a number), add
12048 MaxKeepAliveRequests directive. [Alexei Kosut]
12050 *) Various NeXT compilation patches, as well as a change in
12051 regex/regcomp.c since that file also used a NEXT define.
12054 *) Allow * to terminate the end of a directory match in mod_dir.
12055 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
12057 *) Don't call can_exec() if suexec_enabled. Calling this requires
12058 scripts executed by the suexec wrapper to be world executable, which
12059 defeats one of the advantages of running the wrapper. [Randy Terbush]
12061 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
12064 *) Migration from sprintf() to snprintf() to avoid buffer
12065 overflows. [Marc Slemko]
12067 *) Provide portable snprintf() implementation (ap_snprintf)
12068 as well as *cvt family. [Jim Jagielski]
12070 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
12073 *) Remove mod_fastcgi.c from the distribution. This module appears
12074 to be maintained more through the Open Market channels and should
12075 continue to be easily available at http://www.fastcgi.com/
12077 *) Fixed bug in modules/Makefile that wouldn't allow building in more
12078 than one subdirectory (or cleaning, either). [Jeremy Laidman]
12080 *) mod_info assumed that the config files were relative to ServerRoot.
12083 *) CGI scripts called as an error document resulting from failed
12084 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
12086 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
12089 *) Properly check errno to prevent display of a directory index
12090 when server receives a long enough URL to confuse stat().
12093 *) Several security enhancements to suexec wrapper. It is _highly_
12094 recommended that previously installed versions of the wrapper
12095 be replaced with this version. [Randy Terbush, Jason Dour]
12097 - ~user execution now properly restricted to ~user's home
12098 directory and below.
12099 - execution restricted to UID/GID > 100
12100 - restrict passed environment to known variables
12101 - call setgid() before initgroups() (portability fix)
12102 - remove use of setenv() (portability fix)
12104 *) Add HTTP/1.0 response forcing. [Ben Laurie]
12106 *) Add access control via environment variables. [Ben Laurie]
12108 *) Add rflush() function. [Alexei Kosut]
12110 *) remove duplicate pcalloc() call in new_connection().
12112 *) Fix incorrect comparison which could allow number of children =
12113 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
12114 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
12116 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
12117 AIX PS/2, CONVEXOS. [Jim Jagielski]
12119 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
12120 It's more portable. [Martin Kraemer]
12122 *) Replace references to make in Makefile.tmpl with $(MAKE).
12125 *) Add ProxyBlock directive w/IP address caching. Add IP address
12126 caching to NoCache directive as well. ProxyBlock works with all
12127 handlers; NoCache now also works with FTP for anonymous logins.
12128 Still more code cleanup. [Chuck Murcko]
12130 *) Add "header parse" API hook [Ben Laurie]
12132 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
12134 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
12136 *) Correctly allow access and auth directives in <Files> sections in
12137 server config files. [Alexei Kosut]
12139 *) Fix bug with ServerPath that could cause certain files to be not
12140 found by the server. [Alexei Kosut]
12142 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
12143 double-quote from text and so that it properly checks for unsupported
12144 status codes using the new index_of_response interface. [Roy Fielding]
12146 *) Multiple fixes to the lingering_close code in order to avoid being
12147 interrupted by a stray timeout, to avoid lingering on a connection
12148 that has already been aborted or never really existed, to ensure that
12149 we stop lingering as soon as any error condition is received, and to
12150 prevent being stuck indefinitely if the read blocks. Also improves
12151 reporting of error conditions. [Marc Slemko and Roy Fielding]
12153 *) Fixed initialization of parameter structure for sigaction.
12154 [<mgyger itr.ch>, Adrian Filipi-Martin]
12156 *) Fixed reinitializing the parameters before each call to accept and
12157 select, and removed potential for infinite loop in accept.
12158 [Roy Fielding, after useful PR from <adrian virginia.edu>]
12160 *) Fixed condition where, if a child fails to fork, the scoreboard would
12161 continue to say SERVER_STARTING forever. Eventually, the main process
12162 would refuse to start new children because count_idle_servers() will
12163 count those SERVER_STARTING entries and will always report that there
12164 are enough idle servers. [Phillip Vandry]
12166 *) Fixed bug in bcwrite regarding failure to account for partial writes.
12167 Avoided calling bflush() when the client is pipelining requests.
12168 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
12170 *) Added description of "." mode in server-status [Jim Jagielski]
12172 Changes with Apache 1.2b4
12174 *) Fix possible race condition in accept_mutex_init() that
12175 could leave a small security hole open allowing files to be
12176 overwritten in cases where the server UID has write permissions.
12179 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
12181 *) Fix portablity problem in util_script where ARG_MAX may not be
12182 defined for some systems.
12184 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
12187 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
12188 style magic #! token for better script portability. [Garey Smiley]
12190 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
12191 execution for ~userdir CGI. [Jason Dour]
12193 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
12195 *) Fix month off by one in suexec wrapper logging.
12197 Changes with Apache 1.2b3:
12199 *) Fix error in mod_cgi which could cause resources not to be properly
12200 freed, or worse. [Dean Gaudet]
12202 *) Fix find_string() NULL pointer dereference. [Howard Fear]
12204 *) Add set_flag_slot() at the request of Dirk and others.
12207 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
12209 *) Add changes to improve the error message given for invalid
12210 ServerName parameters. [Dirk vanGulik]
12212 *) Add "Authoritative" directive for Auth modules that don't
12213 currently have it. This gives admin control to assign authoritative
12214 control to an authentication scheme and allow "fall through" for
12215 those authentication modules that aren't "Authoritative" thereby
12216 allowing multiple authentication mechanisms to be chained.
12219 *) Remove requirement for ResourceConfig/AccessConfig if not using
12220 the three config file layout. [Randy Terbush]
12222 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
12224 *) Changes to suexec wrapper to fix the following problems:
12225 1. symlinked homedirs will kill ~userdirs.
12226 2. initgroups() on Linux 2.0.x clobbers gr->grid.
12227 3. CGI command lines paramters problems
12228 4. pw-pwdir for "docroot check" still the httpd user's pw record.
12229 [Randy Terbush, Jason Dour]
12231 *) Change create_argv() to accept variable arguments. This fixes
12232 a problem where arguments were not getting passed to the CGI via
12233 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
12235 *) Collapse multiple slashes in path URLs to properly apply
12236 handlers defined by <Location>. [Alexei Kosut]
12238 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
12240 *) Improve the accuracy of request duration timings by setting
12241 r->request_time in read_request_line() instead of read_request().
12244 *) Reset timeout while reading via get_client_block() in mod_cgi.c
12245 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
12247 *) Add the ability to pass different Makefile.tmpl files to Configure
12248 using the -make flag. [Rob Hartill]
12250 *) Fix coredump triggered when sending a SIGHUP to the server caused
12251 by an assertion failure, in turn caused by an uninitialised field in a
12255 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
12256 PATH_INFO from previous versions of Apache (in certain situations,
12257 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
12258 [later removed in 1.2b11]
12260 *) Add rwrite() function to API to allow for sending strings of
12261 arbitrary length. [Doug MacEachern]
12263 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
12265 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
12266 NeXT. [Jim Jagielski]
12268 *) Removed recent modification to promote the status code on internal
12269 redirects, since the correct fix was to change the default log format
12270 in mod_log_config so that it outputs the original status. [Rob Hartill]
12272 Changes with Apache 1.2b2:
12274 *) Update set_signals() to use sigaction() for setting handlers.
12275 This appears to fix a re-entrant problem in the seg_fault()
12276 bus_error() handlers. [Randy Terbush]
12278 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
12280 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
12282 *) proxy_http.c bugfixes: [Chuck Murcko]
12283 1) fixes possible NULL pointer reference w/NoCache
12284 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
12285 host would cache nothing if it was in the local domain,
12286 and the local domain was in the NoCache list)
12287 3) Adds Host: header when not available
12288 4) Some code cleanup and clarification
12290 *) mod_include.c bugfixes:
12291 1) Fixed an ommission that caused include variables to not
12292 be parsed in config errmsg directives [Howard Fear]
12293 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
12294 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
12295 4) Allow backslash-escaping to all quoted text
12296 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
12297 5) Pass variable to command line if not set in XSSI's env
12300 *) Fix infinite loop when processing Content-language lines in
12301 type-map files. [Alexei Kosut]
12303 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
12305 *) Fixed problem in set_[user|group] that prevented CGI execution
12306 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
12308 *) Added PORTING information file. [Jim Jagielski]
12310 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
12312 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
12314 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
12315 USE_FCNTL_SERIALIZED_ACCEPT was intended.
12317 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
12318 which caused problems of systems where socket s_addr is >32bits.
12320 *) Added comment to explain (r->chunked = 1) side-effect in
12321 http_protocol.c [Roy Fielding]
12323 *) Replaced use of index() in mod_expires.c with more appropriate
12324 and portable isdigit() test. [Ben Laurie]
12326 *) Updated Configure for ...
12327 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
12328 *-dg-dgux* (bad pattern match)
12329 QNX (DEF_WANTHSREGEX=yes)
12330 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
12332 *-unixware211 (new)
12333 and added some user diagnostic info. [Ben Laurie]
12335 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
12336 for better portability. [Jim Jagielski]
12338 *) Updated helpers/GuessOS for ...
12339 SCO 5 (recognize minor releases)
12340 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
12341 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
12342 IRIX64 (-sgi-irix64)
12343 ULTRIX (-unknown-ultrix)
12344 SINIX (-whatever-sysv4)
12345 NCR Unix (-ncr-sysv4)
12346 and fixed something in helpers/PrintPath [Ben Laurie]
12348 Changes with Apache 1.2b1
12350 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
12352 Changes with Apache 1.1.1
12354 *) Fixed bug where Cookie module would make two entries in the
12355 logfile for each access [Mark Cox]
12357 *) Fixed bug where Redirect in .htaccess files would cause memory
12358 leak. [Nathan Neulinger]
12360 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
12362 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
12364 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
12366 Changes with Apache 1.1.0
12368 *) Bring NeXT support up to date. [Takaaki Matsumoto]
12370 *) Bring QNX support up to date. [Ben Laurie]
12372 *) Make virtual hosts default to main server keepalive parameters.
12373 [Alexei Kosut, Ben Laurie]
12375 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
12377 *) Fix missing address family for connect, also remove unreachable statement
12378 in mod_proxy. [Ben Laurie]
12380 *) mod_env now turned on by default in Configuration.tmpl.
12382 *) Bugs which were fixed:
12383 a) yet more mod_proxy bugs [Ben Laurie]
12384 b) CGI works again with inetd [Alexei Kosut]
12385 c) Leading colons were stripped from passwords [<osm interguide.com>]
12386 d) Another fix to multi-method Limit problem [<jk tools.de>]
12388 Changes with Apache 1.1b4
12390 *) r->bytes_sent variable restored. [Robert Thau]
12392 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
12394 *) More possibly unsecure programs removed from the support directory.
12396 *) More mod_auth_msql authentication improvements.
12398 *) VirtualHosts based on Host: headers no longer conflict with the
12401 *) OS/2 compatibility enhancements. [Gary Smiley]
12403 *) POST now allowed to directory index CGI scripts.
12405 *) Actions now work with files of the default type.
12407 *) Bugs which were fixed:
12408 a) more mod_proxy bugs
12409 b) early termination of inetd requests
12410 c) compile warnings on several systems
12411 d) problems when scripts stop reading output early
12413 Changes with Apache 1.1b3
12415 *) Much of cgi-bin and all of cgi-src has been removed, due to
12416 various security holes found and that we could no longer support
12419 *) The "Set-Cookie" header is now special-cased to not merge multiple
12420 instances, since certain popular browsers can not handle multiple
12421 Set-Cookie instructions in a single header. [Paul Sutton]
12423 *) rprintf() added to buffer code, occurrences of sprintf removed.
12426 *) CONNECT method for proxy module, which means tunneling SSL should work.
12427 (No crypto needed) Also a NoCache config directive.
12429 *) Several API additions: pstrndup(), table_unset() and get_token()
12430 functions now available to modules.
12432 *) mod_imap fixups, in particular Location: headers are now complete
12435 *) New "info" module which reports on installed module set through a
12436 special URL, a la mod_status.
12438 *) "ServerPath" directive added - allows for graceful transition
12439 for Host:-header-based virtual hosts.
12441 *) Anonymous authentication module improvements.
12443 *) MSQL authentication module improvements.
12445 *) Status module design improved - output now table-based. [Ben Laurie]
12447 *) htdigest utility included for use with digest authentication
12450 *) mod_negotiation: Accept values with wildcards to be treated with
12451 less priority than those without wildcards at the same quality
12452 value. [Alexei Kosut]
12454 *) Bugs which were fixed:
12455 a) numerous mod_proxy bugs
12456 b) CGI early-termination bug [Ben Laurie]
12457 c) Keepalives not working with virtual hosts
12458 d) RefererIgnore problems
12459 e) closing fd's twice in mod_include (causing core dumps on
12460 Linux and elsewhere).
12462 Changes with Apache 1.1b2
12465 a) core dumps in mod_digest
12466 b) truncated hostnames/ip address in the logs
12467 c) relative URL's in mod_imap map files
12469 Changes with Apache 1.1b1
12471 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12473 Changes with Apache 1.0.3
12475 *) Internal redirects which occur in mod_dir.c now preserve the
12476 query portion of a request (the bit after the question mark).
12479 *) Escape active characters '<', '>' and '&' in html output in
12480 directory listings, error messages and redirection links.
12483 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12485 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12488 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12490 *) Reset timeout timer after each successful fwrite() to the network.
12491 This patch adds a reset_timeout() procedure that is called by
12492 send_fd() to reset the timeout ever time data is written to the net.
12495 *) timeout() signal handler now checks for SIGPIPE and reports
12496 lost connections in a more user friendly way. [Rob Hartill]
12498 *) Location of the "scoreboard" file which used to live in /tmp is
12499 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12500 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12502 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12504 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12505 which caused a SEGV with cookies enabled
12507 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12510 *) Log the UNIX textual error returned by some system calls, in
12511 particular errors from accept() [David Robinson]
12513 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12515 Changes with Apache 1.0.2
12517 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12518 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12520 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12523 *) past changes to http_config.c to only use the
12524 setrlimit function on systems defining RLIMIT_NOFILE
12525 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12526 for SUNOS and prototypes the needed functions.
12528 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12531 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12533 *) Merge multiple headers from CGI scripts instead of taking last
12534 one. [David Robinson]
12536 *) Add support for SCO 5. [Ben Laurie]
12538 Changes with Apache 1.0.1
12540 *) Silence mod_log_referer and mod_log_agent if not configured
12543 *) Recursive includes can occur if the client supplies PATH_INFO data
12544 and the server provider uses relative links; as file.html
12545 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
12547 *) The replacement for initgroups() did not call {set,end}grent(). This
12548 had two implications: if anything else used getgrent(), then
12549 initgroups() would fail, and it was consuming a file descriptor.
12552 *) On heavily loaded servers it was possible for the scoreboard to get
12553 out of sync with reality, as a result of a race condition.
12554 The observed symptoms are far more Apaches running than should
12555 be, and heavy system loads, generally followed by catastrophic
12556 system failure. [Ben Laurie]
12558 *) Fix typo in license. [David Robinson]
12560 Changes with Apache 1.0.0 23 Nov 1995
12562 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
12564 Changes with Apache 0.8.16 05 Nov 1995
12566 *) New man page for 'httpd' added to support directory [David Robinson]
12568 *) .htgroup files can have more than one line giving members for a
12569 given group (each must have the group name in front), for NCSA
12570 back-compatibility [Robert Thau]
12572 *) Mutual exclusion around accept() is on by default for SVR4 systems
12573 generally, since they generally can't handle multiple processes in
12574 accept() on the same socket. This should cure flaky behavior on
12575 a lot of those systems. [David Robinson]
12577 *) AddType, AddEncoding, and AddLanguage directives take multiple
12578 extensions on a single command line [David Robinson]
12580 *) UserDir can be disabled for a given virtual host by saying
12581 "UserDir disabled" in the <VirtualHost> section --- it was a bug
12582 that this didn't work. [David Robinson]
12584 *) Compiles on QNX [Ben Laurie]
12586 *) Corrected parsing of ctime time format [David Robinson]
12588 *) httpd does a perror() before exiting if it can't log its pid
12589 to the PidFile, to make diagnosing the error a bit easier.
12592 *) <!--#include file="..."--> can no longer include files in the
12593 parent directory, for NCSA back-compatibility. [David Robinson]
12595 *) '~' is *not* escaped in URIs generated for directory listings
12598 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
12600 *) Fixed bug involving handling URIs with escaped %-characters
12601 in redirects [David Robinson]
12603 Changes with Apache 0.8.15 14 Oct 1995
12605 *) Switched to new, simpler license
12607 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
12609 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
12611 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
12613 *) Correctly handles internal redirects to files with names containing '%'
12616 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
12618 *) Use geteuid() rather than getuid() to see if we have root privilege,
12619 so that server correctly resets privilege if run setuid root. [Andrew
12622 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
12625 *) Fix relative URLs in imagemap files [Randy Terbush]
12627 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
12630 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
12631 entries all name the same one. [David Robinson]
12633 *) Fix directory listings with filenames containing unusual characters
12636 *) Better URI-escaping for generated URIs in directories with filenames
12637 containing unusual characters [Ben Laurie]
12639 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
12641 *) Unblock alarms on error return from spawn_child() [David Robinson]
12643 *) Sample Config files have extra note for SCO users [Ben Laurie]
12645 *) Configuration has note for HP-UX users [Rob Hartill]
12647 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
12649 *) Nuked bogus #define in httpd.h [David Robinson]
12651 *) Better test for whether a system has setrlimit() [David Robinson]
12653 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
12655 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
12658 Changes with Apache 0.8.14 19 Sep 1995
12660 *) Compiles on SCO ODT 3.0 [Ben Laurie]
12662 *) AddDescription works (better) [Ben Laurie]
12664 *) Leaves an intelligible error diagnostic when it can't set group
12665 privileges on standalone startup [Andrew Wilson]
12667 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
12668 that machine, which claims to be BSD but does not support RLIMIT.
12671 *) gcc -Wall no longer complains about an unused variable when util.c
12672 is compiled with -DMINIMAL_DNS [Andrew Wilson]
12674 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
12676 Changes with Apache 0.8.13 07 Sep 1995
12678 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
12680 *) Have built-in imagemap code recognize & honor Point directive [James
12683 *) Generate cleaner directory listings in directories with a mix of
12684 long and short filenames [Rob Hartill]
12686 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
12688 *) Properly default ServerName for virtual servers [Robert Thau]
12690 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
12691 Paul Richards and a cast of thousands...]
12693 *) On self-identified BSD systems (we don't try to guess any more),
12694 allocate a few extra file descriptors per virtual host with setrlimit,
12695 if we can, to avoid running out. [Randy Terbush]
12697 *) Write 22-character lock file name into buffer with enough space
12698 on startup [Konstantin Olchanski]
12700 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
12703 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
12705 *) Suppress -Wall warning by initializing variable in negotiation code
12706 [Tobias Weingartner]
12708 Changes with Apache 0.8.12 31 Aug 1995
12710 *) Doesn't pause three seconds after including a CGI script which is
12711 too slow to die off (this is done by not even trying to kill off
12712 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
12713 after the entire document has been processed). [Robert Thau]
12715 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
12717 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
12719 *) Allows .htaccess files to override <Directory> sections naming the
12720 same directory [David Robinson]
12722 *) Removed an efficiency hack in sub_req_lookup_uri which was
12723 causing certain extremely marginal cases (e.g., ScriptAlias of a
12724 *particular* index.html file) to fail. [David Robinson]
12726 *) Doesn't log an error when the requested URI requires
12727 authentication, but no auth header line was supplied by the
12728 client; this is a normal condition (the client doesn't no auth is
12729 needed here yet). [Robert Thau]
12731 *) Behaves more sanely when the name server loses its mind [Sean Welch]
12733 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
12735 *) RFC931 code no longer passes out name of prior clients on current
12736 requests if the current request came from a server that doesn't
12737 do RFC931. [David Robinson]
12739 *) Configuration script accepts "Module" lines with trailing whitespace.
12742 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
12744 *) Cleaned up comments in mod_cgi.c [Robert Thau]
12746 Changes with Apache 0.8.11 24 Aug 1995
12748 *) Wildcard <Directory> specifications work. [Robert Thau]
12750 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
12752 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
12753 the file being requested itself, in addition to the directories leading
12754 up to it. [Robert Thau]
12756 *) Logs access failures due to symlink checks or invalid client address
12757 in the error log [Roy Fielding, Robert Thau]
12759 *) Symlink checks deal correctly with systems where lstat of
12760 "/path/to/some/link/" follows the link. [Thau, Fielding]
12762 *) Doesn't reset DirectoryIndex to 'index.html' when
12763 other directory options are set in a .htaccess file. [Robert Thau]
12765 *) Clarified init code and nuked bogus warning in mod_access.c
12766 [Florent Guillaume]
12768 *) Corrected several directives in sample srm.conf
12769 --- includes corrections to directory indexing icon-related directives
12770 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
12771 icons for encodings right, and turning on AddEncoding by default).
12774 *) Corrected descriptions of args to AddIcon and AddAlt in command table
12777 *) INSTALL & README mention "contributed modules" directory [Brian
12780 *) Fixed English in the license language... "for for" --> "for".
12783 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
12784 mod_alias.c, merging it almost completely with handling of Alias, and
12785 adding a 'notes' field to the request_rec which allows the CGI module
12786 to discover whether the Alias module has put this request through
12787 ScriptAlias (which it needs to know for back-compatibility, as the old
12788 NCSA code did not check Options ExecCGI in ScriptAlias directories).
12791 Changes with Apache 0.8.10 18 Aug 1995
12793 *) AllowOverride applies to the named directory, and not just
12794 subdirectories. [David Robinson]
12796 *) Do locking for accept() exclusion (on systems that need it)
12797 using a special file created for the purpose in /usr/tmp, and
12798 not the error log; using the error log causes real problems
12799 if it's NFS-mounted; this is known to be the cause of a whole
12800 lot of "server hang" problems with Solaris. [David Robinson;
12801 thanks to Merten Schumann for help diagnosing the problem].
12803 Changes with Apache 0.8.9 12 Aug 1995
12805 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
12807 *) Nested includes see environment variables of the including document,
12808 for NCSA bug-compatibility (some sites have standard footer includes
12809 which try to print out the last-modified date). [Eric Hagberg/Robert
12812 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
12813 URI as a CGI script, even if it would have been treated as something
12814 else if requested directly, for NCSA back-compatibility. (Note that
12815 this means that people who know the name of the script can see the
12816 code just by asking for it). [Robert Thau]
12818 *) New version of dbmmanage script included in support directory as
12821 *) Check if scoreboard file couldn't be opened, and say so, rather
12822 then going insane [David Robinson]
12824 *) POST to CGI works on A/UX [Jim Jagielski]
12826 *) AddIcon and AddAlt commands work properly [Rob Hartill]
12828 *) NCSA server push works properly --- the Arena bug compatibility
12829 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
12830 if you still want the workaround). [Rob Hartill]
12832 *) If client didn't submit any Accept-encodings, ignore encodings in
12833 content negotiation. (NB this will all have to be reworked anyway
12834 for the new HTTP draft). [Florent Guillaume]
12836 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
12838 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
12840 *) Give Redirect priority over Alias, for NCSA bug compatibility
12843 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
12844 paralleling earlier bug fix for CGI [David Robinson]
12846 *) If DBM auth is improperly configured, report a server error and don't
12849 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
12850 it seems to work well enough without it (even in a 10 hits/sec
12851 workout), and the overhead for the locking under A/UX is
12852 alarmingly high (though it is very low on other systems).
12853 [Eric Hagberg, Jim Jagielski]
12855 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
12857 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
12858 Behlendorf/Eric Hagberg]
12860 *) More improvements to default Configuration for A/UX [Jim Jagielski]
12862 *) Compiles clean on NEXT [Rob Hartill]
12864 *) Compiles clean on SGI [Robert Thau]
12866 Changes with Apache 0.8.8 08 Aug 1995
12868 *) SunOS library prototypes now never included unless explicitly
12869 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
12870 people using GNU libc on SunOS are screwed by prototypes for the
12873 (Those who wish to compile clean with gcc -Wall on a standard
12874 SunOS setup need the prototypes, and may obtain them using
12875 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
12876 with nonstandard libraries are presumably competent to make their
12879 *) Strips trailing '/' characters off both args to the Alias command,
12880 to make 'Alias /foo/ /bar/' work.
12882 Changes with Apache 0.8.7 03 Aug 1995
12884 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
12885 [reported by David Robinson]
12887 *) Compiles clean on OSF/1 [David Robinson]
12889 *) Added some of the more recent significant changes (AddLanguage stuff,
12890 experimental LogFormat support) to CHANGES file in distribution root
12893 Changes with Apache 0.8.6 02 Aug 1995
12895 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
12896 (If you actually wanted a conditional GET which bypassed the cache, you
12897 couldn't get it). [Reported by Roy Fielding]
12899 *) Properly terminate headers on '304 Not Modified' replies to conditional
12900 GETs --- no browser we can find cares much, but the CERN proxy chokes.
12901 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
12903 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
12905 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
12906 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
12907 and older versions don't set the __SUNPRO_C preprocessor variable). On
12908 all other systems, these are never used anyway. [Reported by Mark Cox].
12910 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
12912 Changes with Apache 0.8.5 01 Aug 1995
12914 *) Added last-minute configurable log experiment, as optional module
12916 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
12917 properly. (One-line fix to http_protocol.c).
12919 *) Work around bogus behavior when reloading from Netscape.
12920 It's Netscape's bug --- for some reason they expect a request with
12921 If-modified-since: to not function as a conditional GET if it also
12922 comes with Pragma: no-cache, which is way out of line with the HTTP
12923 spec (according to Roy Fielding, the redactor).
12925 *) Added parameter to set maximum number of server processes.
12927 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
12930 *) IdentityCheck bugfix [Chuck Murcko].
12932 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
12934 *) More sample config file corrections; add extension to AddType for
12935 *.asis, move AddType generic description to its proper place, and
12936 fix miscellaneous typos. [ Alexei Kosut ]
12938 *) Deleted the *other* reference to the regents from the Berkeley
12939 legal disclaimer (everyplace).
12941 *) Nuked Shambhala name from src/README; had already cleaned it out
12942 of everywhere else.
12944 Changes with Apache 0.8.4
12946 *) Changes to server-pool management parms --- renamed current
12947 StartServers to MinSpareServers, created separate StartServers
12948 parameter which means what it says, and renamed MaxServers to
12949 MaxSpareServers (though the old name still works, for NCSA 1.4
12950 back-compatibility). The old names were generally regarded as
12951 too confusing. Also altered "docs" in sample config files.
12953 *) More improvements to default config files ---
12954 sample directives (commented out) for XBitHack, BindAddress,
12955 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
12956 defaults, AddTypes for send-as-is and imagemap magic types, and
12957 improvements to samples for DirectoryIndex [Alexei Kosut]
12959 *) Yet more improvements to default config files --- changes to
12960 Alexei's sample AddLanguage directives, and sample LanguagePriority
12961 [ Florent Guillaume ]
12963 *) Set config file locations properly if not set in httpd.conf
12966 *) Don't escape URIs in internal redirects multiple times; don't
12967 do that when translating PATH_INFO to PATH_TRANSLATED either.
12970 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
12972 Changes with Apache 0.8.3
12974 *) Edited distribution README to *briefly* summarize installation
12975 procedures, and give a pointer to the INSTALL file in the src/
12978 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
12979 recent NCSA distributions.
12981 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
12982 exist for the same directory, use both and don't segfault. [Reported
12985 *) Proper makefile dependencies [David Robinson]
12987 *) Note (re)starts in error log --- reported by Rob Hartill.
12989 *) Only call no2slash() after get_path_info() has been done, to
12990 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
12991 reported by Andrew Wilson, though this one is probably a real bug]
12993 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
12994 dump core when Referer is not supplied. [Randy Terbush]
12996 *) Lightly edited sample config files to refer people to our documentation
12997 instead of NCSA's, and to list Rob McCool as *original* author (also
12998 deleted his old, and no doubt non-functional email address). Would be
12999 nice to have examples of new features...
13001 Changes with Apache 0.8.2 19 Jul 1995
13003 *) Added AddLanuage code [Florent Guillaume]
13005 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
13007 *) All sorts of problems when MultiViews finds a directory. It would
13008 be nice if mod_dir.c was robust enough to handle that, but for now,
13009 just punt. [reported by Brian Behlendorf]
13011 *) Wait for all children on restart, to make sure that the old socket
13012 is gone and we can reopen it. [reported by Randy Terbush]
13014 *) Imagemap module is enabled in default Configuration
13016 *) RefererLog and UserAgentLog modules properly default the logfile
13019 *) Mark Cox's mod_cookies added to the distribution as an optional
13020 module (commented out in the default Configuration, and noted as
13021 an experiment, along with mod_dld). [Mark Cox]
13023 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
13025 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
13027 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
13029 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
13032 Changes with Apache 0.8.1
13034 *) New imagemap module [Randy Terbush]
13036 *) Replacement referer log module with NCSA-compatible RefererIgnore
13037 [Matthew Gray again]
13039 *) Don't mung directory listings with very long filenames.
13040 [Florent Guillaume]
13042 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
13044 *) New config script. See INSTALL for info. [Robert Thau]
13046 *) Scoreboard mechanism for regulating the number of extant server
13047 processes. MaxServers and StartServers defaults are the same as
13048 for NCSA, but the meanings are slightly different. (Actually,
13049 I should probably lower the MaxServers default to 10).
13051 Before asking for a new connection, each server process checks
13052 the number of other servers which are also waiting for a
13053 connection. If there are more than MaxServers, it quietly dies
13054 off. Conversely, every second, the root, or caretaker, process
13055 looks to see how many servers are waiting for a new connection;
13056 if there are fewer than StartServers, it starts a new one. This
13057 does not depend on the number of server processes already extant.
13058 The accounting is arranged through a "scoreboard" file, named
13059 /tmp/htstatus.*, on which each process has an independent file
13060 descriptor (they need to seek without interference).
13062 The end effect is that MaxServers is the maximum number of
13063 servers on an *inactive* server machine, but more will be forked
13064 off to handle unusually heavy loads (or unusually slow clients);
13065 these will die off when they are no longer needed --- without
13066 reverting to the overhead of full forking operation. There is a
13067 hard maximum of 150 server processes compiled in, largely to
13068 avoid forking out of control and dragging the machine down.
13069 (This is arguably too high).
13071 In my server endurance tests, this mechanism did not appear to
13072 impose any significant overhead, even after I forced it to put the
13073 scoreboard file on a normal filesystem (which might have more
13074 overhead than tmpfs). [Robert Thau]
13076 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
13079 *) Read .htaccess files even in directory with <Directory> section.
13080 (Former incompatibility noted on mailing list, now fixed). [Robert
13083 *) "HEAD /" gives the client a "Bad Request" error message, rather
13084 than trying to send no body *and* no headers. [Cliff Skolnick].
13086 *) Don't produce double error reports for some very obscure cases
13087 mainly involving auth configuration (the "all modules decline to
13088 handle" case which is a sure sign of a server bug in most cases,
13089 but also happens when authentication is badly misconfigured).
13092 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
13093 it's *for*, and this sort of thing really shouldn't be cluttering
13094 up the Makefile). [Robert Thau]
13096 *) Incidental code cleanups in http_main.c --- stop dragging
13097 sa_client around; just declare it where used. [Robert Thau]
13099 *) Another acc-related fix. (It doesn't like const char
13100 in some places...). [Mark Cox]
13102 Changes with Shambhala 0.6.1 13 Jul 1995
13104 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
13105 Also, fixed auth typo in http_protocol.c unmasked by this fix.
13107 *) Compiles clean with acc on SunOS [Paul Sutton]
13109 *) Reordered modules in modules.c so that Redirect takes priority
13110 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
13111 believe it or not, he has an actual site with a ScriptAlias and
13112 a Redirect declared for the *exact same directory*. Even *my*
13113 compatibility fetish wouldn't motivate me to fix this if the fix
13114 required any effort, but it doesn't, so what the hey.
13116 *) Fixed to properly default several server_rec fields for virtual
13117 servers from the corresponding fields in the main server_rec.
13118 [Cliff Skolnick --- 'port' was a particular irritant].
13120 *) No longer kills off nph- child processes before they are
13121 finished sending output. [Matthew Gray]
13123 Changes with Shambhala 0.6.0 10 Jul 1995
13125 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
13126 the connection to the client in an "aborted" state, but otherwise
13127 allow whatever handlers are running to clean up. hard_timeout()s
13128 abort the request in progress completely; anything not tied to some
13129 resource pool cleanup will leak. They're still around because I
13130 haven't yet come up with a more elegant way of handling
13131 timeouts when talking to something that isn't the client. The
13132 default_handler and the dir_handler now use soft timeouts, largely
13133 so I can test the feature. [Robert Thau]
13135 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
13136 the case of log handlers dying prematurely is probably handled VERY
13137 gracelessly at this point, and if the logger stops reading input,
13138 the server will hang. (It is known to correctly restart the
13139 logging process on server restart; this is (should be!) going through
13140 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
13141 script). [Robert Thau]
13143 *) asis files supported (new module). [Robert Thau]
13145 *) IdentityCheck code is compiled in, but has not been tested. (I
13146 don't know anyone who runs identd). [Robert Thau]
13148 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
13149 came in with the request, for NCSA bug-compatibility. [Robert Thau]
13151 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
13153 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
13154 as timeouts are not in scope. [Robert Thau]
13156 *) quoted-string args in config files now handled correctly (doesn't drop
13157 the last character). [Robert Thau; reported by Randy Terbush]
13159 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
13160 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
13162 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
13163 default default type); the former default default behavior when all
13164 type-checkers defaulted had been a core dump. [Paul Sutton]
13166 *) Copy filenames out of the struct dirent when indexing
13167 directories. (On Linux, readdir() returns a pointer to the same
13168 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
13170 Changes with Shambhala 0.5.3 [not released]
13172 *) Default response handler notes "file not found" in the error log,
13173 if the file was not found. [Cliff Skolnick].
13175 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
13176 code no longer sets up bogus PATH_INFO which fakes out the directory
13177 handler). [Cliff Skolnick]
13179 Changes with Shambhala 0.5.2 06 Jul 1995
13181 *) Changes to http_main.c --- root server no longer plays silly
13182 games with SIGCHLD, and so now detects and replaces dying
13183 children. Child processes just die on SIGTERM, without taking
13184 the whole process group with them. Potential problem --- if any
13185 child process refuses to die, we hang in restart.
13186 MaxRequestsPerChild may still not work, but it certainly works
13187 better than it did before this! [Robert Thau]
13189 *) mod_dir.c bug fixes: ReadmeName and HeaderName
13190 work (or work better, at least); over-long description lines
13191 properly terminated. [Mark Cox]
13193 *) http_request.c now calls unescape_url() more places where it
13194 should [Paul Sutton].
13196 *) More directory handling bugs (reported by Cox)
13197 Parent Directory link is now set correctly. [Robert Thau]
13199 Changes with Shambhala 0.5.1 04 Jul 1995
13201 *) Generalized cleanup interface in alloc.c --- any function can be
13202 registered with alloc.c as a cleanup for a resource pool;
13203 tracking of files and file descriptors has been reimplemented in
13204 terms of this interface, so I can give it some sort of a test.
13207 *) More changes in alloc.c --- new cleanup_for_exec() function,
13208 which tracks down and closes all file descriptors which have been
13209 registered with the alloc.c machinery before the server exec()s a
13210 child process for CGI or <!--#exec-->. CGI children now get
13211 started with exactly three file descriptors open. Hopefully,
13212 this cures the problem Rob H. was having with overly persistent
13213 CGI connections. [Robert Thau]
13215 *) Mutual exclusion around the accept() in child_main() --- this is
13216 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
13217 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
13218 This uses fcntl(F_SETLK,...) on the error log descriptor because
13219 flock() on that descriptor won't work on systems which have BSD
13220 flock() semantics, including (I think) Linux 1.3 and Solaris.
13222 This does work on SunOS (when the server is idle, only one
13223 process in the pool is waiting on accept()); it *ought* to work
13224 on the other systems. [Robert Thau]
13226 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
13228 *) sizeof(*sa_client) bugfix from [Rob Hartill]
13230 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
13232 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
13233 be unnecessary if I go to the revised timeout-handling scheme).
13236 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
13237 string) even if none came in with the request. [Robert Thau]
13239 *) CHANGES file added to distribution ;-).
13241 Changes with Shambhala 0.4.5
13243 *) mod_dld --- early dynamic loading support [rst]
13244 *) Add wildcard content handlers for XBITHACK; default_hander now
13245 invoked with that mechanism (as a handler hanging off mod_core) [rst]
13246 *) XBITHACK supported as a wildcard content-handler, and
13247 configurable at run-time (not just at compile time, as in the
13248 "patchy server" releases) [rst]
13250 Changes with Shambhala 0.4.4 30 Jun 1995
13252 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
13253 *) Handle Addtype x/y .z [rst, reported by Cox]
13255 Changes with Shambhala 0.4.3
13257 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
13258 synonymous [rst, terbush]
13260 Changes with Shambhala 0.4.1 28 Jun 1995
13262 *) First-cut virtual host implementation; some refit in the config
13263 reading code, and log management, was necessary to support this [rst]
13264 *) Sub-pool machinery, originally added to avoid excessive storage
13265 allocation on listings of large directories (which turned out to
13266 be the problem that the 0.3 storage accounting was added to
13267 find). Subrequests and mod_dir changed to use subpools. [rst]
13268 *) More memory debugging --- free list consistency checks. [rst]
13269 *) Added err_headers to request_rec, with support elsewhere [rst]
13270 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
13272 Changes with Shambhala 0.3 19 Jun 1995
13274 *) Switch ONE_PROCESS to a runtime command-line option (-X)
13275 *) Don't compile in mod_ai_backcompat by default
13276 *) Switch name of server from Apache to Shambhala in Makefile
13277 *) Add some accounting routines to track memory usage in the pools,
13280 Changes with Shambhala 0.2
13282 *) Set DOCUMENT_ROOT CGI variable
13283 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
13284 *) Add critical section protection to handling of cleanup structures
13286 *) Significant code reorg within the server core to group related
13287 functions together [rst]
13288 *) Correctly handle clients that hang up before sending any request
13290 *) Replace dying child processes. [rst]
13292 Changes with Shambhala 0.1 12 Jun 1995
13294 Major rewrite of the pre-existing "patchy server" codebase, by
13295 Robert Thau (rst). Significant portions of the server code, such
13296 as configuration-file handling and HTTP authentication support,
13297 were ripped out and rewritten from scratch. Code that was not
13298 completely rewritten was significantly altered.
13300 Major changes with this release include:
13302 *) Introduction of the module API; in request handling, the central
13303 machinery just dispatches to various modules, which actually do
13304 most of the work. Configuration handling is similar --- modules
13305 declare their own commands, and the central machinery just
13306 dispatches to them.
13308 API features from shambhala/0.1 were substantially unchanged in
13309 Apache 1.0 and 1.1. (1.0 API features not yet present in this
13310 release, such as wildcard handlers and subpools, were added in
13311 subsequent Shambhala releases, and were also generally rst's
13314 *) This release included the following modules:
13316 mod_access (access control --- allow and deny directives),
13317 mod_alias (Alias and Redirect commands),
13318 mod_auth (straight HTTP authentication, based on flat-files)
13319 mod_auth_dbm (same, with dbm files)
13320 mod_cgi (CGI scripts and, in this release, ScriptAlias)
13321 mod_common_log (CLF access logs; later renamed mod_log_common)
13322 mod_dir (directory indexing)
13323 mod_include (server-side includes)
13324 mod_mime (AddType directives)
13325 mod_negotiation (content negotiation)
13326 mod_userdir (support for users' public_html directories)
13328 It also included a mod_ai_backcompat, which was a private hack
13329 for back-compatibility with rst's own AI-lab servers.
13331 All of these modules were substantially complete, and functional
13332 or nearly so (a few, which implemented features not in use at
13333 Thau's site, required patches of a few lines).
13335 *) sub-request machinery, to allow modules to determine how other
13336 modules would assign MIME types to a given file, or optionally
13337 serve its content (this is heavily used by mod_dir, mod_include
13338 and mod_negotiation).
13340 *) Resource pool system for keeping track of memory allocated and
13341 files opened in service of a particular request. Much of the
13342 code in the modules (when they weren't rewrites) was adjusted to
13343 replace a pervasive convention of using fixed-size buffers on
13344 the stack with an equally pervasive convention of using memory
13345 allocated with palloc().
13347 *) Reorganization of data structures associated with a given
13348 request to eliminate use of global variables and the troublesome
13349 unmunge_name function (used in NCSA and early Apache releases to
13350 attempt to determine the URI which mapped to a given filename
13351 --- a difficult proposition, given that it is easy to produce
13352 setups in which multiple URIs map to the same file).
13354 *) Source files renamed and rearranged
13356 *) Very simple pre-forking behavior --- parent process forked off a
13357 fixed number of children, and then just waited for SIGHUP.
13359 *) Other more minor changes too numerous to list.
13361 This release included modified versions of a lot of code from the
13362 Apache 0.6.4 public release, plus an early pre-forking patch
13363 codeveloped by Robert Thau and Rob Hartill.
13365 Changes with Apache 0.7.3 20 Jun 1995
13367 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
13368 were incorporated by Rob Hartill on the main branch while Robert Thau
13369 worked on the Shambhala rewrite above. Most were merged into the
13370 Shambala architecture after Apache 0.8.0.
13372 Changes with Apache 0.6.4 13 May 1995
13374 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
13377 Changes with Apache 0.5.1 10 Apr 1995
13379 Changes with Apache 0.4 02 Apr 1995
13381 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
13384 Changes with Apache 0.3 24 Mar 1995
13386 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
13389 Changes with Apache 0.2 18 Mar 1995
13391 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
13392 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
13393 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
