6 failed" messages during restart and problem with the logger
7 respawning again after Apache is stopped. PR 21648, PR 24805.
10 *) Add a hook (insert_error_filter) to allow filters to re-insert
11 themselves during processing of error responses. Enable mod_expires
12 to use the new hook to include Expires headers in valid error
13 responses. This addresses an RFC violation. It fixes PRs 19794,
14 24884, and 25123. [Paul J. Reder]
16 *) Fix <Limit> and <LimitExcept> parsing to require a closing '>'
17 in the initial container. PR 25414.

24 directory, display the MPM name and some MPM properties.
25 [Geoffrey Young <geoff apache.org>]
27 *) Fixed cache-removal order in mod_mem_cache.
28 [Jean-Jacques Clar, Cliff Woolley]
30 *) Add fatal exception hook for use by debug modules. The hook is only
31 available if the --enable-exception-hook configure parm is used.
34 *) mod_ssl/mod_status: Re-enable support for output of SSL session
35 cache information in server-status page. [Joe Orton]
37 *) mod_ssl: Remove the shmht session cache, shmcb should be used
40 *) mod_ssl: SSL_VERSION_LIBRARY is set to the version string from the
41 SSL library used at run-time, rather than at compile-time.
42 PR: 23956 [Eric Seidel <eseidel apple.com>]
44 *) SECURITY [CAN-2003-0020]: Escape arbitrary data before writing
45 into the errorlog. [André Malo]
47 *) mod_logio: Account for some bytes handed to the network layer prior to
48 dropped connections. [Jeff Trawick]
50 *) mod_autoindex: new directive IndexStyleSheet
51 [Tyler Riddle <triddle_1999 yahoo.com>, Paul Querna <chip force-elite.com>]

85 filesystem name are rejected with 403. [Jeff Trawick]
87 *) Switch to APR 1.0 API.
89 *) Fix mod_include's expression parser to recognize strings correctly
90 even if they start with an escaped token. [André Malo]
92 *) Major overhaul of mod_include's filter parser. The new parser code
93 is expected to be more robust and should catch all of the edge cases
94 that were not handled by the previous one. This includes a binary
95 incompatible change of mod_include's external API. [André Malo]
97 *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
98 PR 14223. [André Malo]
100 *) mod_rewrite: Catch an edge case, where strange subsequent RewriteRules
101 could lead to a 400 (Bad Request) response. [André Malo]
103 *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously
104 the current rewrite state was just used as lookup path, which lead to
105 strange and often useless results. Related to PR 8493. [André Malo]

108 not specified. [Justin Erenkrantz]
110 *) Correct failure with Listen directives on machines with IPv6 enabled.

113 *) Fix a link failure in mod_ssl when the OpenSSL libraries contain
114 the ENGINE functions but the engine header files are missing.
117 *) mod_dav: Use bucket brigades when reading PUT data. This avoids
118 problems if the data stream is modified by an input filter. PR 22104.
119 [Tim Robbins <tim robbins.dropbear.id.au>, André Malo]
121 *) mod_rewrite: RewriteRules in server context using the force
122 type feature [T=...] no longer disable MultiViews. [André Malo]
124 *) mod_rewrite: In external rewrite maps lookup keys containing
125 a newline now cause a lookup failure. PR 14453.
126 [Cedric Gavage <cedric.gavage unixtech.be>, André Malo]
128 *) mod_rewrite: Allow piped rewrite logs to be relative to ServerRoot.
131 *) mod_authz_groupfile: Strip trailing spaces of group names. This
132 hopefully saves some hours of searching for typos. PR 12863.
135 *) mod_actions: Propagate the handler name to the action script via
136 the REDIRECT_HANDLER environment variable. [André Malo]
138 *) mod_actions: Introduce the "virtual" modifier to the Action directive,
139 which allows the use of handlers for virtual locations. PR 8431.
142 *) mod_speling: Recognize AcceptPathInfo setting for the particular
143 location. Default is to reject path information. PR 21059.
146 *) mod_ext_filter: Add the ability to filter request bodies.
147 [Philipp Reisner <philipp.reisner linbit.com>]

156 ExpiresByType. PR#7991 [Ken Coar]
158 *) Fix a problem with namespace mappings being dropped in mod_dav_fs;
159 if any property values were set which defined namespaces these
160 came out mangled in the PROPFIND response. PR 11637.
161 [Amit Athavale <amit_athavale persistent.co.in>]
163 *) prefork MPM: Use the right permissions for the directory created
164 for gprof support. [Jim Carlson <jcarlson jnous.com>]
166 *) Fix a compile failure with recent OpenSSL and picky compilers
167 (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
169 *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
170 the INCLUDE path to be defined properly.
171 PR 11310. [Geoff Thorpe <geoff geoffthorpe.net>]
173 *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
175 *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
176 autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc).
177 [Geoff Thorpe <geoff geoffthorpe.net>]
179 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
180 [Ian Holsman, André Malo]
182 *) mod_negotiation: quality values are now parsed independent from
183 the current locale. level values are now really parsed as integers.
184 PR 17564. [André Malo]
186 *) Added the WindowsSocketsWorkaround directive for Windows NT/2000/XP
187 to work around problems with certain VPN and Firewall products that
188 have buggy AcceptEx implementations.
189 [Allan Edwards w/ suggestions from Bill Stoddard & Bill Rowe]
191 *) Extend mod_negotiation to evaluate the environment variables
192 no-gzip and gzip-only-text/html the same way as mod_deflate does.
195 *) mod_rewrite: Fix some problems reporting errors with mapping
196 programs (RewriteMap prg:/something). [Jeff Trawick]
198 *) Return 413 if chunk-ext-header is too long rather than reading from
199 the truncated line. PR 15857. [Justin Erenkrantz]
201 *) Allow restart of httpd to occur even with syntax errors in the config
202 file. PR 16813. [Justin Erenkrantz]
204 *) Use APR_LAYOUT instead of APACHE_LAYOUT in configure. PR 15679.
207 *) Remove files on 'make distclean' that should be. PR 15592.

219 *) Forward port of mod_actions' ability to handle arbitrary methods
220 with the Script directive. [André Malo]

223 was violated. This message appears in the error log and allows
224 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
226 *) Modify buildconf to copy all required files into httpd's tree.
227 [Thom May <thom planetarytramp.net>]
229 *) Allow mod_dav to do weak entity comparison functions.
232 *) Move RFC 1413 ident requests from core to new module mod_ident.

239 *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
242 *) Replace some of the mutex locking in the worker MPM with
243 atomic operations for higher concurrency. [Brian Pane]
245 *) Allow 'make depend' to work with non-GCC compilers.
248 *) If an httpd.conf has commented out AddModule directives,
249 apxs -i -a will add an un-commented AddModule directive for
250 the new module, which breaks the config.
251 PR: 11212 [Joe Orton]
253 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
255 *) Move the check of the Expect request header field after the hook
256 for ap_post_read_request, since that is the only opportunity for
257 modules to handle Expect extensions. [Justin Erenkrantz]
259 *) Rewrite of aaa modules to an authn/authz model.
260 [Dirk-Willem van Gulik, Justin Erenkrantz]
263 [Apache 2.1.0-dev includes those bug fixes and changes with the

273 Includes a patch submitted by Sushma Rai <rsushma novell.com>.
274 This fixes mod_mem_cache but not mod_disk_cache yet so I'm not
275 closing the PR since that is what they are using. [Paul J. Reder]
277 *) complain via error_log when mod_include's INCLUDES filter is
278 enabled, but the relevant Options flag allowing the filter to run
279 for the specific resource wasn't set, so that the filter won't
280 silently get skipped. next remove itself, so the warning will be
281 logged only once [Stas Bekman, Jeff Trawick, Bill Rowe]

298 *) mod_ssl: Fix segfaults at startup if other modules which use OpenSSL
299 are also loaded. [Joe Orton]
301 *) mod_ssl: Use human-readable OpenSSL error strings in logs; use
302 thread-safe interface for retrieving error strings. [Joe Orton]
304 *) mod_expires: Initialize ExpiresDefault to NULL instead of "" to
305 avoid reporting an Internal Server error if it is used without
306 having been set in the httpd.conf file. PR: 23748, 24459
307 [Andre Malo, Liam Quinn <liam htmlhelp.com>]
309 *) mod_autoindex: Don't omit the <tr> start tag if the SuppressIcon
310 option is set. PR 21668. [Jesse Tie-Ten-Quee <highos highos.com>]
312 *) mod_include no longer allows an ETag header on 304 responses.
313 PR 19355. [Geoffrey Young <geoff apache.org>, André Malo]
315 *) EBCDIC: Convert header fields to ASCII before sending (broken
316 since 2.0.44). [Martin Kraemer]
318 *) Fix the inability to log errors like exec failure in
319 mod_ext_filter/mod_cgi script children. This was broken after
320 such children stopped inheriting the error log handle.
323 *) Fix mod_info to use the real config file name, not the default
324 config file name. [Aryeh Katz <aryeh secured-services.com>]
326 *) Set the scoreboard state to indicate logging prior to running

345 arguments in the opening tag) supported by httpd 1.3. Without
346 this change mod_perl 2.0's <Perl> sections are broken.
347 ["Philippe M. Chiasson" <gozer cpan.org>]

424 *) Install config.nice into the build/ directory to make
425 minor version upgrades easier. [Joshua Slive]
427 *) Fix mod_deflate so that it does not call deflate() without checking

485 the ServerTokens directive. [Jeff Trawick]
487 Changes with Apache 2.0.47
489 *) SECURITY [CAN-2003-0192]: Fixed a bug whereby certain sequences
490 of per-directory renegotiations and the SSLCipherSuite directive
491 being used to upgrade from a weak ciphersuite to a strong one
492 could result in the weak ciphersuite being used in place of the
493 strong one. [Ben Laurie]

509 [William Rowe, Jeff Trawick, André Malo]
511 *) core_output_filter: don't split the brigade after a FLUSH bucket if
512 it's the last bucket. This prevents creating unneccessary empty
513 brigades which may not be destroyed until the end of a keepalive
515 [Juan Rivera <Juan.Rivera citrix.com>]
517 *) Add support for "streamy" PROPFIND responses.
518 [Ben Collins-Sussman <sussman collab.net>]
520 *) mod_cgid: Eliminate a double-close of a socket. This resolves
521 various operational problems in a threaded MPM, since on the
522 second attempt to close the socket, the same descriptor was
523 often already in use by another thread for another purpose.
526 *) mod_negotiation: Introduce "prefer-language" environment variable,
527 which allows to influence the negotiation process on request basis
528 to prefer a certain language. [André Malo]

563 [Andreas Leimbacher <andreasl67 yahoo.de>, Madhusudan Mathihalli]
565 *) Add a delete flag to htpasswd.
568 *) Fix mod_rewrite's handling of absolute URIs. The escaping routines
569 now work scheme dependent and the query string will only be
570 appended if supported by the particular scheme. [André Malo]
572 *) Add another check for already compressed content in mod_deflate.
573 PR 19913. [Tsuyoshi SASAMOTO <nazonazo super.win.ne.jp>]

576 from the source tree as well as the build tree (now creates a usable
577 configuration for apxs), and eliminated redundant -I'nclude paths.
580 *) Code fixes, constness corrections and ssl_toolkit_compat.h updates
581 for SSLC and OpenSSL toolkit compatibility. Still work remains to
582 be done to cripple features based on the limitations of RSA's binary
583 distribution of their SSL-C toolkit.
584 [William Rowe, Madhusudan Mathihalli, Jeff Trawick]

1141 *) SECURITY [CAN-2002-0840]: HTML-escape the address produced by
1142 ap_server_signature() against this cross-site scripting
1143 vulnerability exposed by the directive 'UseCanonicalName Off'.
1144 Also HTML-escape the SERVER_NAME environment variable for CGI
1145 and SSI requests. It's safe to escape as only the '<', '>',
1146 and '&' characters are affected, which won't appear in a valid
1147 hostname. Reported by Matthew Murphy <mattmurphy kc.rr.com>.
1150 *) Fix a core dump in mod_cache when it attemtped to store uncopyable
1151 buckets. This happened, for instance, when a file to be cached
1152 contained SSI tags to execute a CGI script (passed as a pipe
1153 bucket). [Paul J. Reder]
1155 *) Ensure that output already available is flushed to the network
1156 when the content-length filter realizes that no new output will
1157 be available for a while. This helps some streaming CGIs as
1158 well as some other dynamically-generated content. [Jeff Trawick]
1160 *) Fix a mutex problem in mod_ssl session cache support which
1161 could lead to an infinite loop. PR 12705
1162 [Amund Elstad <amund.elstad ergo.no>, Jeff Trawick]
1164 *) SECURITY [CAN-2002-1156] (cve.mitre.org):
1165 Fix the exposure of CGI source when a POST request is sent to
1166 a location where both DAV and CGI are enabled. [Ryan Bloom]
1168 *) Allow the UserDir directive to accept a list of directories.
1169 This matches what Apache 1.3 does. Also add documentation for
1170 this feature. [Jay Ball <jay veggiespam.com>]
1172 *) New Module: mod_logio. adds the ability to log bytes sent and
1173 received. [Bojan Smojver <bojan rexursive.com>]
1175 *) SuExec needs to use the same default directory as the rest of
1176 server, namely /usr/local/apache2.
1177 [SangBeom han <sbhan os.korea.ac.kr>]
1179 *) Get mod_auth_ldap to retry connections on LDAP_SERVER_DOWN.
1180 [Thomas Bennett <thomas.bennett eds.com>, Graham Leggett]
1182 *) Make sure the contents of the WWW-Authenticate header is
1183 passed on a 4xx error by proxy. Previously all headers
1184 were dropped, resulting in the browser being unable to
1185 authenticate. [Dr Richard Reiner <rreiner fscinternet.com>,
1186 Richard Danielli <rdanielli fscinternet.com>, Graham Wiseman
1187 <gwiseman fscinternet.com>, David Henderson
1188 <dhenderson fscinternet.com>]
1190 *) Make mod_cache's CacheMaxStreamingBuffer directive work
1191 properly for virtual hosts that override server-wide mod_cache
1192 setttings. [Matthieu Estrade <estrade-m ifrance.com>]
1194 *) Add -p option to apxs to allow programs to be compiled with apxs.
1197 Changes with Apache 2.0.42
1199 *) mod_dav: Check for versioning hooks before using them.
1202 Changes with Apache 2.0.41
1204 *) The protocol version (eg: HTTP/1.1) in the request line parsing
1205 is now case insensitive. [Jim Jagielski]
1207 *) Allow AddOutputFilterByType to add multiple filters per directive.
1210 *) Remove warnings with Sun's Forte compiler. [Justin Erenkrantz]
1212 *) Fixed mod_disk_cache's generation of 304s
1213 [Kris Verbeeck <Kris.Verbeeck ubizen.com>]
1215 *) Add support for using fnmatch patterns in the final path
1216 segment of an Include statement (eg.. include /foo/bar/*.conf).
1217 and remove the noise on stderr during config dir processing.
1218 [Joe Orton <jorton redhat.com>]
1220 *) mod_cache: cache_storage.c. Add the hostname and any request
1221 args to the key generated for caching. This provides a unique
1222 key for each virtual host and for each request with unique
1223 args. [Paul J. Reder, args code provided by Kris Verbeeck]
1225 *) mod_cache: Do not cache responses to GET requests with query
1226 URLs if the origin server does not explicitly provide an
1227 Expires header on the response (RFC 2616 Section 13.9)
1228 [Kris Verbeeck <krisv be.ubizen.com>]
1230 *) Fix memory leak in core_output_filter. [Justin Erenkrantz]
1232 *) Update OpenSSL detection to work on Darwin.
1233 [Sander Temme <sctemme covalent.net>]
1235 *) Update the xslt and css to give the documentation a more
1237 [André Malo <nd perlig.de>, Gernot Winkler <greh o3media.de>]
1239 *) Fix some bucket memory leaks in the chunking code
1240 [Joe Schaefer <joe+apache sunstarsys.com>]
1242 *) Add ModMimeUsePathInfo directive. [Justin Erenkrantz]
1244 *) mod_cache: added support for caching streamed responses (proxy,
1245 CGI, etc) with optional CacheMaxStreamingBuffer setting [Brian Pane]
1247 *) Add image/x-icon to httpd.conf PR 10993.
1248 [Ian Holsman, Peter Bieringer <pb bieringer.de>]
1250 *) Fix FileETags none operation. PR 12207.
1251 [Justin Erenkrantz, Andrew Ho <andrew tellme.com>]
1253 *) Restored the experimental leader/followers MPM to working
1254 condition and converted its thread synchronization from
1255 mutexes to atomic CAS. [Brian Pane]
1257 *) Fix Logic on non-html file removal in mod_deflate
1258 [Kris Verbeeck <Kris.Verbeeck ubizen.com>]
1260 *) Fix "ab -g"'s truncated year: the last digit was cut off.
1261 [Leon Brocard <acme astray.com>]
1263 *) mod_rewrite can now sets cookies in err_headers, uses the correct
1264 expiry date, and can now set the path as well
1265 PR 12132,12181,12172.
1266 [Ian Holsman / Rob Cromwell <apachechangelog robcromwell.com>]
1268 *) The content-length filter no longer tries to buffer up
1269 the entire output of a long-running request before sending
1270 anything to the client. [Brian Pane]
1272 *) Win32: Lower the default stack size from 1MB to 256K. This will
1273 allow around 8000 threads to be started per child process.
1274 'EDITBIN /STACK:size apache.exe' can be used to change this
1275 value directly in the apache.exe executable.
1278 *) Win32: Implement ThreadLimit directive in the Windows MPM.
1281 *) Remove CacheOn config directive since it is set but never checked.
1282 No sense wasting cycles on unused code. Besides, the only truly
1283 bug free code is deleted code. :) [Paul J. Reder]
1285 *) BufferLogs are now run-time enabled, and the log_config now has 2 new
1286 callbacks to allow a 3rd party module to actually do the writing of the
1287 log file [Ian Holsman]
1289 *) Correct ISAPIReadAheadBuffer to default to 49152, per mod_isapi docs.
1290 [André Malo, Astrid Keßler <kess kess-net.de>]
1292 *) Fix Segfault in mod_cache. [Kris Verbeeck <Kris.Verbeeck ubizen.com>]
1294 *) Fix a null pointer dereference in the merge_env_dir_configs
1295 function of the mod_env module. PR 11791
1298 *) New option to ServerTokens 'maj[or]'. Only show the major version
1299 Also Surfaced this directive in the standard config (default FULL)
1302 *) Change mod_rewrite to use apr-util's dbm support for dbm rewrite
1303 maps. The dbm type (e.g., ndbm, gdbm) can be specified on the
1304 RewriteMap directive. PR 10644 [Jeff Trawick]
1306 *) Fixed mod_rewrite's RewriteMap prg: support so that request/response
1307 pairs will no longer get out of sync with each other. PR 9534
1310 *) Fixes required to get quoted and escaped command args working in
1311 mod_ext_filter. PR 11793 [Paul J. Reder]
1313 *) mod-proxy: handle proxied responses with no status lines
1314 [JD Silvester <jsilves uwo.ca>, Brett Huttley <brett huttley.net>]
1316 *) Fix bug where environment or command line arguments containing
1317 non-ASCII-7 characters would cause the Win32 child process creation
1318 to fail. PR 11854 [William Rowe]
1320 *) Bug #11213.. make module loading error messages more informative
1321 [Ian Darwin <Ian779 darwinsys.com>]
1323 *) thread safety & proxy-ftp [Alexey Panchenko <alexey liwest.ru>, Ian Holsman]
1325 *) mod_disk_cache works much better. This module should still
1326 be considered experimental. [Eric Prud'hommeaux]
1328 *) Performance improvement for keepalive requests: when setting
1329 aside a small file for potential concatenation with the next
1330 response on the connection, set aside the file descriptor rather
1331 than copying the file into the heap. [Brian Pane]
1333 *) Modified version check on openssl so that it finds the executable
1334 first and then performs a check of the version, only warning the
1335 user if they chose, or we selected, an old version of OpenSSL.
1336 This change also allows the code to work for non-openssl libraries
1337 selected via the --with-ssl=dir option, which can override the
1338 automated library check in any case. [Roy Fielding]
1340 Changes with Apache 2.0.40
1342 *) SECURITY [CAN-2002-0661] (cve.mitre.org):
1343 Close a very significant security hole that
1344 applies only to the Win32, OS2 and Netware platforms. Unix was not
1345 affected, Cygwin may be affected. Certain URIs will bypass security
1346 and allow users to invoke or access any file depending on the system
1347 configuration. Without upgrading, a single .conf change will close
1348 the vulnerability. Add the following directive in the global server
1349 httpd.conf context before any other Alias or Redirect directives;
1350 RedirectMatch 400 "\\\.\."
1351 Reported by Auriemma Luigi <bugtest sitoverde.com>.
1354 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1355 Close a path-revealing exposure in multiview type
1356 map negotiation (such as the default error documents) where the
1357 module would report the full path of the typemapped .var file when
1358 multiple documents or no documents could be served based on the mime
1359 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
1362 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1363 Close a path-revealing exposure in cgi/cgid when we
1364 fail to invoke a script. The modules would report "couldn't create
1365 child process /path-to-script/script.pl" revealing the full path
1366 of the script. Reported by Jim Race <jrace qualys.com>.
1369 *) Set aside the apr-iconv and apr_xlate() features for the Win32
1370 build of 2.0.40 so development can be completed. A patch, from
1371 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
1372 will be available for those that wish to work with apr-iconv.
1375 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
1376 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
1378 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
1379 set to 1, so we can exclude things from the general case with
1380 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
1382 *) Accept multiple leading /'s for requests within the DocumentRoot.
1383 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
1385 *) Solved the reports of .pdf byterange failures on Win32 alone.
1386 APR's sendfile for the win32 platform collapses header and trailer
1387 buffers into a single buffer. However, we destroyed the pointers
1388 to the header buffer if a trailer buffer was present. PR 10781
1391 *) mod_ext_filter: Add the ability to enable or disable a filter via
1392 an environment variable. Add the ability to register a filter of
1393 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
1395 *) Restore the ability to specify host names on Listen directives.
1396 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh yahoo.com>]
1398 *) When deciding on the default address family for listening sockets,
1399 make sure we can actually bind to an AF_INET6 socket before
1400 deciding that we should default to AF_INET6. This fixes a startup
1401 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
1403 *) Replace usage of atol() to parse strings when we might want a
1404 larger-than-long value with apr_atoll(), which returns long long.
1405 This allows HTTPD to deal with larger files correctly.
1406 [Shantonu Sen <ssen apple.com>]
1408 *) mod_ext_filter: Ignore any content-type parameters when checking if
1409 the response should be filtered. Previously, "intype=text/html"
1410 wouldn't match something like "text/html;charset=8859_1".
1413 *) mod_ext_filter: Set up environment variables for external programs.
1414 [Craig Sebenik <craig netapp.com>]
1416 *) Modified the HTTP_IN filter to immediately append the EOS (end of
1417 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
1418 the caller to determine that no content remains without prefetching
1419 additional POST body. [William Rowe]
1421 *) Get proxy ftp to work over IPv6. [Shoichi Sakane <sakane kame.net>]
1423 *) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml suse.de>]
1425 *) Update SuSE layout. [Peter Poeml <poeml suse.de>]
1427 *) Changes to the internationalized error documents:
1428 Comment them out in the default config file to make the default
1429 install as simple as possible; Correct the english 500 error to
1430 be more understandable; Add a Swedish translation.
1431 [Thomas Sjogren <thomas northernsecurity.net>,
1432 Erik Abele <erik codefaktor.de>, Rich Bowen, Joshua Slive]
1434 *) Increase the limit on file descriptors per process in apachectl.
1437 *) Fix a dependency error when building ApacheMonitor, so that Win32
1438 and MSVC now trust that the project is current (when it is).
1439 [James Cox <imajes php.net>]
1441 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
1442 [Arthur P. Smith <apsmith aps.org>, Jeff Trawick]
1444 *) APR-Util Renames pending have been completed [Thom May]
1446 *) Performance improvements for the code that reads request
1447 headers (ap_rgetline_core() and related functions) [Brian Pane]
1449 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
1450 to configure the maximum amount of memory the allocators will
1451 hold on to for reuse. Anything over the MaxMemFree threshold
1452 will be free()d. This directive is useful when uncommon large
1453 peaks occur in memory usage. It should _not_ be used to mask
1454 defective modules' memory use. [Sander Striker]
1456 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
1457 scripts would not result in a truncated response.
1458 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
1460 *) Add a filter_init parameter to the filter registration functions
1461 so that a filter can execute arbitrary code before the handlers
1462 are invoked. This resolves a problem where mod_include requests
1463 would incorrectly return a 304. [Justin Erenkrantz]
1465 *) Fix a long-standing bug in 2.0, CGI scripts were being called
1466 with relative paths instead of absolute paths. Apache 1.3 used
1467 absolute paths for everything except for SuExec, this brings back
1468 that standard. [Ryan Bloom]
1470 *) Fix infinite loop due to two HTTP_IN filters being present for
1471 internally redirected requests. PR 10146. [Justin Erenkrantz]
1473 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
1476 *) Fix mod_ext_filter to look in the main server for filter definitions
1477 when running in a vhost if the filter definition is not found in
1478 the vhost. PR 10147 [Jeff Trawick]
1480 *) Support WinNT CGI invocation through ScriptInterpreterSource
1481 'registry' for script interpreter paths and names with non-ascii
1482 characters in the executable filepath. [William Rowe]
1484 *) Support the -w flag on to keep the Win32 console open on error.
1487 *) Normalize the hostname value in the request_rec to all-lowercase
1488 [Perry Harrington <pedward webcom.com>]
1490 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
1491 extended characters (non US-ASCII) in non-utf8 format. This brings
1492 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
1493 to the cgi application itself. [William Rowe]
1495 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
1496 modules to bring them up to the current apr/apr-util APIs.
1499 *) Fix segfault in mod_mem_cache most frequently observed when
1500 serving the same file to multiple clients on an MP machine.
1503 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
1504 [Brian Degenhardt <bmd mp3.com>, Ian Holsman]
1506 *) Fix perchild to work with apachectl by adding -k support to perchild.
1507 PR 10074 [Jeff Trawick]
1509 *) Fix a silly htpasswd.c logic error that incorrectly reported that
1510 both -c and -n had been used. PR 9989 [Cliff Woolley]
1512 *) Fixed a mod_include error case in which no HTTP response was sent
1513 to the client if an shtml document contained an unterminated SSI
1514 directive [Brian Pane]
1516 *) Improve ap_get_client_block implementation by using APR-util brigade
1517 helper functions and relying on current filter assumptions.
1520 Changes with Apache 2.0.39
1522 *) Fixed a build problem in htpasswd.c on Win32.
1523 [Guenter Knauf <eflash gmx.net>, Cliff Woolley]
1525 Changes with Apache 2.0.38
1527 *) Rewrite htpasswd to use APR. The removes the annoying warning about
1528 tmpnam being unsafe. [Ryan Bloom]
1530 *) We must set the MIME-type for .shtml files to text/html if we want them
1531 to be parsed for SSI tags. Add the config for that to the default
1532 config file so that it is easier to enable .shtml parsing.
1533 [Dave Dyer <ddyer real-me.net>]
1535 *) Fixed a problem with 'make install' on ReliantUnix.
1536 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
1538 *) Make the default_handler catch all requests that aren't served by
1539 another handler. This also gets us to return a 404 if a directory
1540 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1541 loaded. [Justin Erenkrantz]
1543 *) Fixed the handling of nested if-statements in shtml files.
1544 PR 9866 [Brian Pane]
1546 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1547 into a directory different from the one that was configured. This
1548 also mirrors the root= feature from 1.3. We cannot use prefix=,
1549 because both APR and APR-util resolve their installation paths at
1550 configuration time. This means that there is no variable prefix
1551 to replace. [Andreas Hasenack <andreas netbank.com.br>]
1553 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1554 These levels of AIX don't have a thundering herd problem with
1555 accept(). [Jeff Trawick]
1557 *) prefork MPM: Ignore mutex errors during graceful restart. For
1558 certain types of mutexes (particularly SysV semaphores), we
1559 should expect to occasionally fail to obtain or release the
1560 mutex during restart processing. [Jeff Trawick]
1562 *) Fix install-bindist.sh so that it finds any perl instead of just
1563 early perl 5.x versions. This is consistent with a build/install
1564 from source, and it allows the perl scripts installed by a bindist
1565 to work on systems with perl 5.6. [Jeff Trawick]
1567 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
1568 Tru64 (and probably some other platforms). [Jeff Trawick]
1570 *) Allow CGI scripts to return their Content-Length. This also fixes a
1571 hang on HEAD requests seen on certain platforms (such as FreeBSD).
1574 *) Added log rotation based on file size to the RotateLog support
1575 utility. [Brad Nicholes]
1577 *) Fix some casting in mod_rewrite which broke random maps.
1578 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
1580 Changes with Apache 2.0.37
1582 *) allow POST method over SSL when per-directory client cert
1583 authentication is used with 'SSLOptions +OptRenegotiate' enabled
1584 and a client cert was found in the ssl session cache.
1586 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
1587 session cache when there is no cert chain in the cache. prior to
1588 the fix this situation would result in a FORBIDDEN response and
1589 error message "Cannot find peer certificate chain"
1592 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
1593 one was already sent. PR 9644 [Jeff Trawick]
1595 *) Fix the display of the default name for the mime types config
1596 file. PR 9729 [Matthew Brecknell <mbrecknell orchestream.com>]
1598 *) Fix the working directory *for WinNT/2K/XP services only* to

1600 of Apache.exe, in the case that Apache.exe resides in bin/.)
1601 Solves the case of ServerRoot /foo paths where /foo was not
1602 on the same drive as /winnt/system32. [William Rowe]
1604 *) Make 2.0's "AcceptMutex" startup message now "completely"
1605 match how 1.3 does it. [Jim Jagielski]
1607 *) Implement a fixed size memory cache using a priority queue
1610 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
1611 querying certain other variables from config_vars.mk. PR 9316
1614 *) Added the "detached" attribute to the cgi_exec_info_t internals
1615 so that Win32 and Netware won't create a new window or console
1616 for each CGI invoked. PR 8387
1617 [Brad Nicholes, William Rowe]
1619 *) Consolidated the command line parameters and attributes that are
1620 manipulated by the optional function ap_cgi_build_command() in
1621 mod_cgi into a single structure.
1624 *) Get rid of uninitialized value errors with "apxs -q" on certain
1625 variables. [Stas Bekman <stas stason.org>]
1627 *) Fix apxs to allow it to work when the build directory is somewhere
1628 besides server-root/build. PR 8453
1629 [Jeff Trawick and a host of others]
1631 *) Allow ap_discard_request_body to be called multiple times in the
1632 same request. Essentially, ap_http_filter keeps track of whether
1633 it has sent an EOS bucket up the stack, if so, it will only ever
1634 send an EOS bucket for this request.
1635 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
1637 *) Remove all special mod_ssl URIs. This also fixes the bug where
1638 redirecting (.*) will allow an SSL protected page to be viewed
1639 without SSL. [Ryan Bloom]
1641 *) Fix the binary build install script so that the build logic
1642 created by "apxs -g" will work when the user has a binary
1643 build. [Jeff Trawick]
1645 *) Allow instdso.sh to work with full paths to the shared module.
1648 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
1649 in module for NetWare [Brad Nicholes]
1651 *) Changed cgi and piped log behavior to accept 65536 characters
1652 on Win32 (matching Linux) before deadlocking between outputing
1653 client stdin, slurping the output from stdout and then the stderr
1654 stream. PR 8179 [William Rowe]
1656 *) Fixed Win32 wintty.exe support to assure the window title is valid.
1657 Elimiates possible gpfault or garbage title without the -t option.
1660 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
1661 brigades and input filters. [Justin Erenkrantz]
1663 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
1664 body. [Justin Erenkrantz]
1666 *) NetWare: Piping log entries through RotateLogs using the
1667 CustomLogs directive is finally supported now that we have
1668 the pipes and spawning functionality working.
1671 *) SECURITY [CVE-2002-0392] (cve.mitre.org) [CERT VU#944335]:

1680 on sub-requests or when the connection will be dropped.
1683 *) Fix the TIME_* SSL var lookups to be threadsafe. PR 9469.
1686 *) Ensure that apr_brigade_write() flushes in all of the cases that

1927 explicitly tell the server that warning messages should be sent
1928 to the client in addition to being recorded in the error log.
1929 Prior to this change, ap_log_rerror() always sent warning
1930 messages to the client. In one case, a faulty CGI script caused
1931 the server to send a warning message to the client that contained
1932 the full path to the CGI script. This could be considered a
1933 minor security exposure. [Bill Stoddard]
1935 *) mod_autoindex output when SuppressRules was specified would

1949 *) Change instdso.sh to use libtool --install everywhere and then
1950 clean up some stray files and symlinks that libtool leaves around
1951 on some platforms. This gets subversion building properly since
1952 it needed a re-link to be performed by libtool at install time,
1953 and the old instdso.sh logic to simply cp the DSO didn't handle
1954 that requirement. [Sander Striker]

1965 *) Fix segfault in mod_mem_cache when garabge collecting an expired
1966 cache entry. [Bill Stoddard]
1968 *) Introduced -E startup_logfile_name option to httpd to allow admins
1969 to begin logging errors immediately. This provides Win32 users
1970 an alternative to sending startup errors to the event viewer, and
1971 allows other daemon tool authors an alternative to logging to stderr.

2060 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
2061 cause the Apache parent process to run in the foreground (similar to
2062 -DNO_DETACH except that it doesn't switch session ids).
2065 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
2066 for those platforms that support it. If using the default
2067 implementation, this is between pthread and sysvsem in priority.
2068 This implies it's the new default for Darwin. [Jim Jagielski]
2070 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
2071 environment variables in the envvars file. [Jeff Trawick]

2156 *) Added exp_foo and rel_foo variables to config_vars.mk for
2157 all Apache and Autoconf path variables (like --sysconfdir,
2158 --sbindir, etc). exp_foo is the "expanded" version, which means
2159 that all internal variable references have been interpolated.

2161 share a common path. [Aaron Bannert]
2163 *) Fix some restart/terminate problems in the worker MPM. Don't

2252 *) Modify receive/send loop in proxy_http and proxy_ftp so that
2253 should it be necessary, the remote server socket is closed before
2254 transmitting the last buffer (set by ProxyIOBufferSize) to the

2269 have gotten back an IPv6 address first and yet our system is not
2270 configured to allow IPv6 sockets. [Jeff Trawick]
2272 *) Be more careful about recursively removing CVS directories. Make
2273 sure that we aren't cd'ing to their home directory first. PR: 9993
2274 [Aaron Bannert, James LewisMoss <dres lewismoss.net>]
2276 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
2277 [Dirk-Jan Faber <dirk-jan selwerd.nl>, Aaron Bannert,
2278 Thom May <thom planetarytramp.net>]
2280 *) Rename the filter ordering priorities. The recent filtering fixes
2281 have showcased problems with their usage. Therefore, we need to
2282 rename them to increase the clarity. (CONTENT->RESOURCE,
2283 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
2285 Changes with Apache 2.0.33
2287 *) Fix a problem in the new --enable-layout functionality where
2288 it wouldn't allow overrides from variables like --prefix,
2289 --bindir, etc. [Thom May <thom planetarytramp.net>]
2291 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
2292 no longer hangs around waiting for the socket to close before
2293 returning exhaustive data. [Aaron Bannert]
2295 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
2296 [Thom May <thom planetarytramp.net>]
2298 *) Change mod_ssl to always do a full startup/teardown on restarts.
2299 this allows mod_ssl to be added to a server that is already
2300 running and makes it possible to add/change certs/keys after the
2301 server has been started. [Doug MacEachern]
2303 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
2304 This pipe must be a bidirectional 'console' style relay, which
2305 mod_ssl prints all prompts to the pipe's stdin, and reads the
2306 passphrases from the pipe's stdout. [William Rowe]
2308 *) Fix bug where --sysconfdir and --localstatedir were being
2309 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
2312 *) Fix --enable-layout to work again. Caution: When specifying
2313 --enable-layout, common arguments like --prefix, --exec-prefix,
2314 etc. will be ignored and the settings from the layout will be
2315 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]
2318 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
2319 regex pattern matching for the determination of which requests
2320 to use the remote proxy for. [Jim Jagielski]
2322 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
2324 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
2325 cruft in piped logs and rewritemap child processes.
2328 *) All instances of apr_lock_t have been removed and converted
2329 to one of the following new lock APIs: apr_thread_mutex.h,
2330 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
2331 use the apr_lock.h API, as the old API will soon be deprecated.
2334 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
2335 [Ralf S. Engelschall, Cliff Woolley]
2337 *) mod-include: make it handle flush'es and fix the 'false-alarm'
2338 [Justin Erenkrantz, Brian Pane, Ian Holsman]
2340 *) ap_get_*_filter_handle() functions to allow 3rd party modules
2341 to lookup filter handles so they can bypass the filter name
2342 lookup when adding filters to a request (via ap_add_*_filter_handle())
2343 [Ryan Morgan <rmorgan covalent.net>]
2345 *) Fix for multiple file buckets on Win32, where the first file
2346 bucket would cause the immediate closure of the socket on any
2347 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
2349 *) Correct Win32 failure of mmap of a segment beyond start of the
2350 file; fixes large SSL and similar transfers. [William Rowe]
2353 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
2354 multi-process mode to not "daemonize" while detaching from the
2355 controlling terminal. This is necessary for Apache to work with
2356 process-management tools like AIX's "System Resource Controller"
2357 as well as Dan Bernstein's "daemontools".
2358 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
2360 *) Convert mod_auth_digest to use the new apr_global_mutex_t
2361 type. [Aaron Bannert]
2363 *) fix bug in mod-include where it wouldn't send a unmatched
2364 part if it was at the end of a bucket [Ian Holsman]
2366 *) worker MPM: Improve logging of errors with the interface between
2367 the listener thread and worker threads. [Jeff Trawick]
2369 *) Some browsers ignore cookies that have been merged into a
2370 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
2371 are now unmerged in the http proxy before being sent to the
2372 client. [Graham Leggett]
2374 *) Fix a problem with proxy where each entry of a duplicated
2375 header such as Set-Cookie would overwrite and obliterate the
2376 previous value of the header, resulting in multiple header
2377 values (like cookies) going missing.
2378 [Graham Leggett, Joshua Slive]
2380 *) Add the server-limit and thread-limit values to the scoreboard
2381 for the sake of third-party applications.
2382 [Adam Sussman <myddryn vishnu.vidya.com>]
2384 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
2386 *) OS/390: Get make install to properly copy DSO modules.
2389 *) Win32: Fix bug in mod_status with displaying "Restart Time"
2390 and "Server uptime".
2393 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
2395 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
2397 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
2398 [David MacKenzie <djm pix.net>]
2400 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
2401 [David MacKenzie <djm pix.net>]
2403 *) Fix segfault and display error when SSLMutex file can not be
2404 created. [Adam Sussman <myddryn vishnu.vidya.com>]
2406 *) Add reference counting to mod_mem_cache cache objects to
2407 better manage removing objects from the cache.
2410 *) Change the verbage on the ScoreBoardFile in our default configs.
2411 Also change the default to be commented out (unspecified) so we
2412 get anonymous shared memory by default. [Aaron Bannert]
2414 *) Implement new ScoreBoardFile directive logic. This affects how
2415 we create the scoreboard's shared memory segment. If the directive
2416 is present, a name-based segment is created. If the directive is
2417 not present, first an anonymous segment is created, and if that
2418 fails, a name-based segment is created from a file of the name
2419 DEFAULT_SCOREBOARD. This gives third-party applications the
2420 ability to access our scoreboard. [Aaron Bannert]
2422 *) Allow mod_deflate to work with non-GET requests and properly send
2423 Content-Lengths. [Sander Striker <striker apache.org>]
2425 *) Fix ap_directory_merge() to correctly merge configs when there is
2426 no <Directory /> block. [Justin Erenkrantz, William Rowe]
2428 *) Remove spurious debug messsages that are normal under HTTP
2429 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
2431 *) Fix a bug in mod_cgid that would prevent proper shutdown death
2432 of the cgid process. [Aaron Bannert]
2434 *) Add signal handling back in to the worker MPM for the one_process
2435 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
2437 *) Performance: Reuse per-connection transaction pools in the
2438 worker MPM, rather than destroying and recreating them. [Brian Pane]
2440 *) Remove all signals from the worker MPM's child process. Instead,
2441 the parent uses the Pipe of Death for all communication with the
2442 child processes. [Ryan Bloom]
2444 Changes with Apache 2.0.32
2446 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
2447 default if the directive is not specified. This mirrors older
2448 behavior without changes to the httpd.conf. [William Rowe]
2450 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
2451 the service, mpm and logging code, and bugs in apr_file_open_stderr
2452 and apr_file_dup2 functions. Win2K/XP services have no handles
2453 associated for stdin/out/err, which caused unpredictable behavior
2454 in the prior release. [William Rowe, Bill Stoddard]
2456 *) Win32: simplify the Application Event Log messages, since there isn't
2457 likely to be 'more information in the error log' before an error log
2458 has been opened. [William Rowe]
2460 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
2461 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
2463 *) Win32: apache -k shutdown now behaves like apache -k stop.
2466 *) Fix prefork to not kill the parent if a child hits a resource shortage
2467 on accept(). [Greg Ames]
2469 *) Fix seg faults that occur when what should be the httpd request line
2470 starts with \r\n followed by garbage. [Greg Ames]
2472 *) Allow statically linked support binaries with the new
2473 --enable-static-support flag, and enable this behavior in
2474 the binbuild script. Also add a new --enable-static-htdbm
2475 flag. [Aaron Bannert]
2477 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
2478 do only one stat() call when generating the directory listings.
2481 *) Fix resolve_symlink to save the original symlink name if known.
2484 *) Be a bit more sane with regard to CanonicalNames. If the user has
2485 specified they want to use the CanonicalName, but they have not
2486 configured a port with the ServerName, then use the same port that
2487 the original request used. [Ryan Bloom and Ken Coar]
2489 *) In core_input_filter, check for an empty brigade after
2490 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
2491 client says it will post some data but we get FIN before any
2492 data arrives. [Jeff Trawick]
2494 *) Not being able to bind to the socket is a fatal error. We should
2495 print an error to the console, and return a non-zero status code.
2496 With these changes, all of the Unix MPMs do that correctly.
2499 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
2500 through to CGI scripts. PR 9163
2501 [Brian Reid <breid customlogic.com>,
2502 Zvi Har'El <rl math.technion.ac.il>]
2504 *) binbuild.sh: Make sure that we use the expat from our source
2505 tree so that there aren't any surprises on the target machine.
2508 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2509 enough to keep up with new requests. Start using
2510 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2511 when we can't talk to the daemon. [Jeff Trawick]
2513 *) apxs: LTFLAGS envvar can override default libtool options. Try
2514 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2515 the covers. [Jeff Trawick]
2517 *) The Location: response header field, used for external
2518 redirect, *must* be an absoluteURI. The Redirect directive
2519 tested for that, but RedirectMatch didn't -- it would allow
2520 almost anything through. Now it will try to turn an abs_path
2521 into an absoluteURI, but it will correctly varf like Redirect
2522 if the final redirection target isn't an absoluteURI. [Ken Coar]
2524 Changes with Apache 2.0.31
2526 *) Create the scoreboard (in the parent) in a global pool context,
2527 so it survives graceful restarts. This fixes a SEGV during
2528 graceful restarts. [Aaron Bannert]
2530 *) Add a timeout option to the proxy code 'ProxyTimeout'
2533 *) FTP directory listings are now always retrieved in ASCII mode.
2534 The FTP proxy properly escapes URI's and HTML in the generated
2535 listing, and escapes the path components when talking to the FTP
2536 server. It is now possible to browse the root directory by using
2537 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2538 Also, the last path component may contain wildcard characters
2539 '*' and '?', and if they do, a directory listing is created instead
2540 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2543 *) Added single-listener unserialized accept support to the
2544 worker MPM [Brian Pane]
2546 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2547 the incoming host header through to the proxied server
2548 [Geoff <g.russell ieee.org>]
2550 *) New Directive Option for ProxyPass. It now can block a location
2551 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
2553 *) Don't let the default handler try to serve a raw directory. At
2554 best you get gibberish. Much worse things can happen depending
2555 on the OS. [Jeff Trawick]
2557 *) Change the pre_config hook to return a value. Modules can now emit
2558 an error message and then cause the server to quit gracefully during
2559 startup. This required a bump to the MMN. [Aaron Bannert]
2561 *) Fix some unix socket descriptor leaks in the handler side of
2562 mod_cgid (the part that runs in the server process). Whack a
2563 silly "close(-1)" in the handler too. [Jeff Trawick]
2565 *) Change the pre_mpm hook to return a value, so that scoreboard
2566 init errors percolate up to code that knows how to exit
2567 cleanly. This required a bump to the MMN. [Jeff Trawick]
2569 *) Add the socket back to the conn_rec and remove the create_connection
2570 hook. The create_connection hook had a design flaw that did not
2571 allow creating connections based on vhost info. [Bill Stoddard]
2573 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2574 Resolves the common case of using negotation to resolve the request
2575 /script/foo for /script.cgi/foo. [William Rowe]
2577 *) Added new functions ap_add_(input|output)_filter_handle to
2578 allow modules to bypass the usual filter name lookup when
2579 adding hard-coded filters to a request [Brian Pane]
2581 *) caching should now work on subrequests (still very experimental)
2584 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2586 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2589 *) Refactor ap_rgetline so that it does not use an internal brigade.
2590 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2592 *) Remove mod_auth_db. [Justin Erenkrantz]
2594 *) Do not install unnecessary pcre headers like config.h and internal.h.
2595 [Joe Orton <joe manyfish.co.uk>]
2597 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
2598 (as it does for a normal request). quick_handled sub-requests now work
2599 in mod-include [Ian Holsman]
2601 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
2602 'CONTENT' one, as it needs to run AFTER all content headers
2604 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
2607 *) Split out blocking from the mode in the input filters.
2610 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
2612 *) Cause Win32 to capture all child-worker process errors in
2613 Apache to the main server error log, until the child can
2614 open its own error logs. [William Rowe]
2616 *) HPUX 11.*: Do not kill the child process when accept()
2617 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
2618 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
2620 *) Fix a problem in the parsing of the <Proxy foo> directive.
2623 *) rewrite of mod_ssl input filter for better performance and less
2624 memory usage [Doug MacEachern]
2626 *) allow quick_handler to be run on subrequests. [Ian Holsman]
2628 *) mod_dav now asks its provider to place content directly into the
2629 filter stack when handling a GET request. The mod_dav/provider
2630 API has changed, so providers need to be updated. [Greg Stein]
2632 *) Clear the output socket descriptor in unixd_accept() to make sure
2633 we don't supply a bogus socket to the caller if the accept fails.
2634 This caused problems with the worker MPM, which tried to process
2635 the returned socket if it was non-NULL. [Brian Pane]
2637 *) Move a check for an empty brigade to the start of core input filter
2638 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
2640 *) Add FileETag directive to allow configurable control of what
2641 data are used to form ETag values for file-based URIs. MMN
2642 bumped to 20020111 because of fields added to the end of
2643 the core_dir_config structure. [Ken Coar]
2645 *) Fix a segfault in mod_rewrite's logging code caused by passing the
2646 wrong config to ap_get_remote_host(). [Jeff Trawick]
2648 *) Allow mod_cgid to work from a binary distribution install by
2649 using 755 for the permissions on the log directory instead of
2652 *) Fixed a segfault that happened during graceful shutdown (or when
2653 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
2655 *) Split all Win32 modules [excluding the core components mod_core,
2656 mod_so, mod_win32 and the winnt mpm] into individual loadable
2657 modules, so the administrator may individually disable the former
2658 compiled-in modules by simply commenting out their LoadModule
2659 directives. [William Rowe]
2661 *) Saved Win32 module authors and porters many future headaches, by
2662 duplicating the appropriate .h files such as os.h into the include
2663 directory, including in the build tree. [William Rowe]
2665 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
2666 Use SSL functions/macros instead of directly dereferencing SSL
2667 structures wherever possible.
2668 Add type-casts for the cases where functions return a generic pointer.
2669 Add $SSL/include to configure search path.
2670 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
2672 *) Moved several pointers out of the shared Scoreboard so it is
2673 more portable, and will present the vhost name across server
2674 generation restarts. [William Rowe]
2676 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
2679 Changes with Apache 2.0.30
2681 *) Fix the main bug for FreeBSD and threaded MPM's. There are
2682 still issues (see STATUS) but at least the server will now
2683 run without crashing the machine.
2684 [David Reid, Aaron Bannert, Justin Erenkrantz]
2686 *) Fix a typo in mod_deflate's m4 config section.
2687 [albert chin <china thewrittenword.com>]
2689 *) Fix a couple of mod_proxy problems forwarding HTTP connections
2690 and handling CONNECT:
2691 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
2692 (2) Proxy failed to connect when the first IP address returned by
2693 the resolver was unreachable but a secondary IP address was.
2696 *) Fix the module identifer as shown in the docs for various core
2697 modules (e.g., the identifer for mod_log_config was previously
2698 listed as config_log_module). PR #9338
2699 [James Watson <ap2bug sowega.org>]
2701 *) Fix LimitRequestBody directive by placing it in the HTTP
2702 filter. [Justin Erenkrantz]
2704 *) Fix mod_proxy seg fault when the proxied server returns
2705 an HTTP/0.9 response or a bogus status line.
2708 *) Prevent mod_proxy from truncating one character off the
2709 end of the status line returned from the proxied server.
2710 [Adam Sussman, Bill Stoddard]
2712 *) Eliminate loop in ap_proxy_string_read().
2713 [Adam Sussman, Bill Stoddard]
2715 *) Provide $0..$9 results from mod_include regex parsing.
2718 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
2720 *) Introduced the ForceLanguagePriority directive, to prevent
2721 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
2722 when using Multiviews. [William Rowe]
2724 *) Fix a problem which prevented mod_cgid and suexec from working
2725 together reliably [Greg Ames]
2727 *) Remove the call to exit() from within mod_auth_digest's post_config
2728 phase. [Aaron Bannert]
2730 *) Fix a problem in mod_auth_digest that could potentially cause
2731 problems with initialized static data on a system that uses DSOs.
2734 *) Fix a segfault in the worker MPM that could happen during
2735 child process exits. [Brian Pane, Aaron Bannert]
2737 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
2739 *) Fix matching of vhosts by ip address so we find IPv4
2740 vhost address when target address is v4-mapped form of
2741 that address. [Jeff Trawick]
2743 *) More performance tweaks to the BNDM string-search algorithm
2744 used to find "<!--#" tokens in mod_include [Brian Pane]
2746 *) Miscellaneous small performance fixes: optimized away various
2747 string copy operations and removed large temp buffers from
2748 the stack [Brian Pane]
2750 *) Fixed startup segfault that occurred when a VirtualHost
2751 directive had a port but no address [Brian Pane]
2753 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
2755 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
2756 if oslevel < WINNT. This should fix several problems reported
2757 Against 2.0.28 on Windows 98 [Bill Stoddard]
2759 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
2760 to fail. [Bill Stoddard]
2762 *) Change core code to allow an MPM to set hard thread/server
2763 limits at startup. prefork, worker, and perchild MPMs now have
2764 directives to set these limits. [Jeff Trawick]
2766 *) Win32: The async AcceptEx() event should be autoreset upon
2767 successful completion of a wait (WaitForSingleObject). This
2768 eliminates a number of spurious
2769 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
2772 *) Move any load library path environment variables out of
2773 apachectl and into a separate environment variable file which
2774 can be more easily tailored by the admin. The environment
2775 variable file as built by Apache may have additional system-
2776 specific settings. For example, on OS/390 we tailor the heap
2777 settings to allow lots of threads. [Jeff Trawick]
2779 *) Use the new APR pool code to reduce pool-related lock
2780 contention in the worker MPM. [Sander Striker]
2782 *) The POD no longer assumes the child is listening on 127.0.0.1
2783 and now pulls the first hostname in the list of listeners to
2784 perform the dummy connect on. This fixes a bug when the user
2785 had configured the Listen directive for an IP other than
2786 127.0.0.1. This would result in undead children and error
2787 messages such as "Connection refused: connect to listener".
2790 *) The worker MPM now respects the LockFile setting, needed to
2791 avoid locking problems with NFS. [Jeff Trawick]
2793 *) Fix segfault when worker MPM receives SIGHUP.
2794 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
2796 *) Fix bug that could potentially prevent the perchild MPM from
2797 working with more than one vhost/uid. [Aaron Bannert]
2799 *) Change make install and apxs -i processing of DSO modules to
2800 perform special handling on platforms where libtool doesn't install
2801 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
2802 which prevented standard LoadModule statements from working.
2805 *) Whenever mod_so is enabled (not just when there are DSOs for
2806 our modules), do whatever special magic is required for compiling/
2807 loading third-party modules. This allows third-party DSOs to
2808 be used on an AIX build when there were no built-in modules
2809 built as DSOs. (This should help on OS/390 and BeOS as well.)
2812 *) Allow apxs to be used to build DSOs on AIX without requiring the
2813 user to hard-code the list of import files. (This should help
2814 on OS/390 and BeOS as well.) [Jeff Trawick]
2816 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
2817 PR 8563, 8919 [William Rowe]
2819 *) Get binary builds working when libapr and libaprutil are built
2822 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
2823 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
2824 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
2826 *) Fix the handling of SSI directives in which the ">" of the
2827 terminating "-->" is the last byte in a file [Brian Pane]
2829 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
2830 message that we had back in apache-1.3 and still have scattered
2831 throughout our docs. [Aaron Bannert]
2833 *) Prevent the Win32 port from continuing after encountering an
2834 error in the command line args to apache. [William Rowe]
2836 *) On a error in the proxy, make it write a line to the error log
2839 *) Various mod_ssl performance improvements [Doug MacEachern]
2841 Changes with Apache 2.0.29
2843 *) Add buffering in core_output_filter to ensure that long
2844 lists of small buckets don't cause small packet writes.
2845 [Brian Pane, Ryan Bloom]
2847 *) Fix the installation target to make sure that the manual is
2848 installed in the correct location.
2849 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
2850 Gomez Henri <hgomez slib.fr>]
2852 *) Fix the cmd command for mod_include. When we are processing
2853 a cmd command, we do not want to use the r->filename to set
2854 the command name. The command comes from the SSI tag. To do this,
2855 I added a variable to the function that builds the command line
2856 in mod_cgi. This allows the include_cmd function to specify
2857 the command line itself. [Ryan Bloom]
2859 *) Change open_logs hook to return a value, allowing you
2860 to flag a error while opening logs
2861 [Ian Holsman, Doug MacEachern]
2863 *) Change post_config hook to return a value, allowing you
2864 to flag a error post config
2865 [Ian Holsman, Jeff Trawick]
2867 *) Allow SUEXEC_BIN (the path to the suexec binary that is
2868 hard-coded into the server) to be specified to the configure
2869 script by the --with-suexec-bin parameter. [Aaron Bannert]
2871 *) Fix segv in worker MPM following accept on pipe-of-death
2874 *) Add mod_deflate to experimental.
2875 [Ian Holsman, Justin Erenkrantz]
2877 *) Bail out at configure time if an invalid MPM was specified.
2878 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
2880 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
2881 configured [John Sterling <sterling covalent.net>]
2883 *) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>]
2885 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
2887 *) Optimization for the BNDM string-search function in
2888 mod_include. [Brian Pane]
2890 *) Fixed the behavior of the XBitHack directive.
2891 [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
2893 *) The threaded MPM for Unix has been removed. Use the worker
2894 MPM instead. [various]
2896 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
2897 in logging the error from a failed DNS lookup. [Jeff Trawick]
2899 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
2902 *) Get mod_cgid killed when a MPM exits due to a fatal error.
2905 *) Fix a file descriptor leak in mod_include. When we include a
2906 file, we use a sub-request, but we didn't destroy the sub-request
2907 immediately, instead we waited until the original request was
2908 done. This patch closes the sub-request as soon as the data is
2909 done being generated. [Brian Pane <bpane pacbell.net>]
2911 *) Allow modules that add sockets to the ap_listeners list to
2912 define the function that should be used to accept on that
2913 socket. Each MPM can define their own function to use for
2914 the accept function with the MPM_ACCEPT_FUNC macro. This
2915 also abstracts out all of the Unix accept error handling
2916 logic, which has become out of synch across Unix MPMs.
2919 *) Fix a bug which would cause the response headers to be omitted
2920 when sending a negotiated ErrorDocument because the required
2921 filters were attached to the wrong request_rec.
2922 [John Sterling <sterling covalent.net>]
2924 *) Remove commas from the end of the macros that define
2925 directives that are used by MPMs. Prior to this patch,
2926 you would use these macros without commas, which was unlike
2927 the macros for any other directives. Now, the caller provides
2928 the comma rather than the macro providing it. This makes
2929 the macros look more like the rest of the directives.
2930 [Ryan Bloom and Cliff Woolley]
2932 *) Add 'redirect-carefully' environment option to disable sending
2933 redirects under special circumstances. This is helpful for
2934 Microsoft's WebFolders when accessing a directory resource via
2935 DAV methods. [Justin Erenkrantz]
2937 *) Begin to abstract out the underlying transport layer.
2938 The first step is to remove the socket from the conn_rec,
2939 the server now lives in a context that is passed to the
2940 core's input and output filters. This forces us to be very
2941 careful when adding calls that use the socket directly,
2942 because the socket isn't available in most locations.
2945 *) Really reset the MaxClients value in worker and threaded
2946 when the configured value is not a multiple of the number
2947 of threads per child. We said we did previously but we
2948 forgot to. [Jeff Trawick]
2950 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
2952 *) If shared modules are requested and mod_so is not available,
2953 produce a fatal config-time error. [Justin Erenkrantz]
2955 *) Improve http2env's performance by cutting the work it has to
2956 do. [Brian Pane <bpane pacbell.net>]
2958 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
2959 [Brian Pane <bpane pacbell.net>]
2961 Changes with Apache 2.0.28
2963 *) Fix infinite loop in mod_cgid.c.
2964 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
2966 *) When no port is given in a "ServerName host" directive, the
2967 server_rec->port is now set to zero, not 80. That allows for
2968 run-time deduction of the correct server port (depending on
2969 SSL/plain, and depending also on the current setting of
2970 UseCanonicalName). This change makes redirections
2971 work, even with https:// connections. As in Apache-1.3, the
2972 connection's actual port number is never used, only the ServerName
2973 setting or the client's Host: setting. Documentation updated
2974 to reflect the change. [Martin Kraemer]
2976 *) Add a '%{note-name}e' argument to mod-headers, which works in
2977 the same way as mod_log_confg. [Ian Holsman]
2979 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
2980 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
2981 MPMs. [Cliff Woolley]
2983 *) Introduce htdbm, a user management utility for db/dbm authorization
2984 databases. [Mladen Turk <mturk mappingsoft.com>]
2986 *) Optimize usage of strlen and strcat in ap_directory_walk.
2987 [Brian Pane <bpane pacbell.net>]
2989 Changes with Apache 2.0.27
2991 *) Introduce an Apache mod_ssl initial configuration template
2992 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
2994 *) Fixed a memory leak in the getline parsing code that could
2995 be triggered by arbitrarily large header lines. Requests
2996 from the core input filter for single lines are now limited
2997 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
2999 *) Fix a truncation bug in how we print the port on the Via: header.
3000 The routine that prints the Via: header now takes a length for
3001 the port string. [Zvi Har'El <rl math.technion.ac.il>]
3003 *) Some syntax errors in mod_mime_magic's magic file can result
3004 in a 500 error, which previously was unlogged. Now we log the
3005 error. [Jeff Trawick]
3007 *) Add the support/checkgid helper app, which checks the run-time
3008 validity of group identifiers usable in the Group directive.
3011 *) Various --enable-so options have been fixed: --enable-so is
3012 treated as "static"; explicit --enable-so=shared issues an error;
3013 and explicit --enable-so fails with error on systems without
3014 APR_HAS_DSO. [Aaron Bannert]
3016 *) Fix a segfault in the core input filter when the client socket
3017 gets disconnected unexpectedly. [Cliff Woolley]
3019 *) Fix the reporting for child processes that die. This removes
3020 all of the non-portable W* macros from Apache.
3021 [Jeff Trawick and Ryan Bloom]
3023 *) Win32: Track and display "Parent Server Generation:" in
3024 mod_status output. The generation will be bumped at
3025 server graceful restart, when the child process exits
3026 by hitting MaxRequestsPerChild or if the child
3027 process exits abnormally. [Bill Stoddard]
3029 *) Win32: Fix problem where MaxRequestsPerChild directive was
3030 not being picked up in favor of the default. Enable
3031 the parent to start up a new child process immediately upon
3032 the old child starting shutdown.
3035 *) Fix some bungling of the remote port in rfc1413.c so that
3036 IdentityCheck retrieves the proper user id instead of failing
3037 and thus always returning "nobody."
3038 [Dick Streefland <Dick.Streefland xs4all.nl>]
3040 *) Introduced thread saftey for mod_rewrite's internal cache.
3041 [Brian Pane <bpane pacbell.net>]
3043 *) Simplified mod_env's directives to behave as most directives are
3044 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
3045 directive following that UnsetEnv within the same container.
3046 Also provides a runtime startup warning if a PassEnv configured
3047 environment value is undefined. [William Rowe]
3049 *) The worker MPM is now completely ported to APR's new lock API. It
3050 uses native APR types for thread mutexes, cross-process mutexes,
3051 and condition variables. [Aaron Bannert]
3053 *) Sync up documentation to remove all references to the now deprecated
3054 Port directive. [Justin Erenkrantz]
3056 *) Moved all ldap modules from the core to httpd-ldap sub-project
3059 *) Exit when we can't listen on any of the configured ports. This
3060 is the same behavior as 1.3, and it avoids having the MPMs to
3061 deal with bogus ap_listen_rec structures. [Jeff Trawick]
3063 *) Cleanup the proxy code that creates a request to the origin
3064 server. This change adds an optional hook, which allows modules
3065 to gain control while the request is created if the proxy module
3066 is loaded. The purpose of this hook is to allow modules to add
3067 input and/or output filters to the request to the origin. While
3068 I was at it, I made the core use this hook, so that proxy request
3069 creation uses some of the code from the core. This can still be
3070 greatly improved, but this is a good start. [Ryan Bloom]
3072 Changes with Apache 2.0.26
3074 *) Port the MaxClients changes from the worker MPM to the threaded
3077 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
3078 with the new input filtering system. [Justin Erenkrantz]
3080 *) Introduce the MultiviewsMatch directive, to allow the operator
3081 to be flexible in recognizing Handlers and Filters filename
3082 extensions as part of the Multiviews matching logic, strict with
3083 MultiviewsMatch NegotiatedOnly to accept only filename extentions
3084 that designate negotiated parameters, (content type, charset, etc.)
3085 or MultiviewsAll for the 1.3 behavior of matching any files, even
3086 if they have unregistered extensions. [William Rowe]
3088 *) Fixed the configure script to add a LoadModule directive to
3089 the default httpd.conf for any module that was compiled
3090 as a DSO. [Aaron Bannert <aaron clove.org>]
3092 *) rewrite mod_ssl input filtering to work with the new input filtering
3093 system. [Justin Erenkrantz]
3095 *) prefork: Don't segfault when we are able to listen on some but
3096 not all of the configured ports. [Jeff Trawick]
3098 *) Build mod_so even if no core modules are built shared.
3099 [Aaron Bannert <aaron clove.org>]
3101 *) Introduce ap_directory_walk rewrite (with further optimizations
3102 required) to adapt to the ap_process_request_internal() changes.
3103 Optimized so subrequests and redirects now reuse previous section
3104 merges, until we mismatch with the original directory_walk, and
3105 precomputed r->finfo results will cause directory_walk to skip
3106 the most expensive phases of the function. [William Rowe]
3108 *) Allow ApacheMonitor to connect to and control Apache on other
3109 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
3111 *) Remove the Port directive. In it's place, the Listen directive
3112 is now a required directive, which tells Apache what port to
3113 listen on. The ServerName directive has also been extended
3114 to accept an optional port. If the port is specified to the
3115 ServerName, the server will report that port whenever it
3116 reports the port that it is listening on. This change was
3117 made to ease configuration errors that stem from having a Port
3118 directive, and a Listen directive. In that situation, the server
3119 would only listen to the port specified by the Listen command,
3120 which caused a lot of confusion to users. [Ryan Bloom]
3122 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
3123 build, as loadable modules. [William Rowe]
3125 *) Fix --enable-mods-shared processing. If most is specified,
3126 then all modules that can be compiled as shared modules are.
3127 [Aaron Bannert <aaron clove.org>]
3129 *) Update the mime.types file to map video/vnd.mpegurl to mxu
3130 and add commonly used audio/x-mpegurl for m3u extensions.
3131 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
3133 *) Eliminate the depreciated r->content_language, in favor of the array
3134 r->content_languages introduced many years ago. Module authors must
3135 substantially overhaul their modules, so this needs to be upgraded
3136 if the module still relied on backwards-brokeness. [William Rowe]
3138 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
3141 *) Rewrite the input filtering mechanisms to consolidate and reorganize
3142 code. In short, core_input_filter does something now and
3143 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
3145 *) Update the Win32 build to re-absorb mod_proxy and family.
3148 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
3149 current SDK.) [William Rowe]
3151 *) Some style changes to the code that does ProxyErrorOverride. Fixed
3152 config merge behaviour. [Graham Leggett]
3154 *) Allow support programs to be compiled against a static version
3155 of libapr. This allows the smaller support programs to be
3156 relocated. [Aaron Bannert <aaron clove.org>]
3158 *) Update the mime.types file to the registered media types as
3159 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
3161 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
3162 number of clients that can connect at the same time, instead of
3163 specifying the maximum number of child processes.
3164 [Aaron Bannert <aaron clove.org>]
3166 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
3167 be consistent with 1.3. [Justin Erenkrantz]
3169 *) Cache apr_explode_localtime() value for 15 seconds.
3170 [Brian Pane <bpane pacbell.net>]
3172 *) Fix mod_include to not return ETag or Last-Modified headers.
3173 [Ian Holsman <ianh cnet.com>]
3175 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
3177 *) Eliminate the wasteful run-time conversion of method names from strings
3178 to numbers in places where the methods are known at compile time.
3179 [Brian Pane <bpane pacbell.net>]
3181 *) Turn the worker MPM's queue into a LIFO. This may
3182 improve cache-hit performance under some conditions.
3183 [Aaron Bannert <aaron clove.org>]
3185 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
3186 support it. [Justin Erenkrantz]
3188 *) Cleanup the worker MPM. We no longer re-use transaction
3189 pools. This incurs less overhead than shuffling the pools
3190 around so that they can be re-used. Remove one of the
3191 queue's condition variables. We just redefined the API to
3192 state that you can't try to add more stuff than you allocated
3193 segments for. [Aaron Bannert <aaron clove.org>]
3195 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
3197 *) Fixed persistent connections when a request contains a body.
3200 *) mod_dav uses a new API to speak to the backend provider for dead
3201 property management. [Greg Stein]
3203 *) Remove the Win32 script-processing exception from mod_cgi, and
3204 roll build_command_line/build_argv_list into a unified, overrideable
3205 ap_cgi_build_command optional function. [William Rowe]
3207 *) Rewrite find_start_sequence to use a better search algorithm
3208 to find the start tag. [Justin Erenkrantz]
3210 *) Fix a seg fault in mod_include. When we are generating an
3211 internal redirect, we must set r->uri to "", not a bogus
3212 string, and not NULL. [Ryan Bloom]
3214 *) Optimized location_walk, so subrequests, redirects and second passes
3215 now reuse previous section merges on a <Location > by <Location >
3216 basis, until we mismatch with the original location_walk.
3219 *) Back out the 1.45 change to util_script.c. This change made
3220 us set the environment variable REQUEST_URI to the redirected
3221 URI, instead of the originally requested URI.
3222 [Taketo Kabe <kabe sra-tohoku.co.jp>]
3224 *) Make mod_include do lazy evaluation of potentially expensive to
3225 compute variables. [Brian Pane <bpane pacbell.net>]
3227 *) Fix logging of bytes sent for HEAD requests. %b and %B should
3228 log either - or 0, before this patch, they were both logging
3229 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
3231 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
3232 than per character. [Brian Pane <bpane pacbell.net>]
3234 *) Normalize the primary request, redirects and sub-requests to
3235 run the same ap_process_request_internal for consistency in
3236 robustness, behavior and security. [William Rowe]
3238 *) Fix a segfault with mod_include when r->path_info is not set
3239 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
3241 *) Add -X functionality back. This indicates to all MPMs and any other
3242 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
3244 *) Some initial support for the cygwin platform [prefork only].
3245 This is not to be confused with support for the WinNT/Win32
3246 platform, which is the recommended configuration for native
3247 Win32 users. The cygwin platform support is recommended for
3248 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
3250 *) Changed syntax of Set{Input|Output}Filter. The list of filters
3251 must be semicolon delimited (if more than one filter is given.)
3252 The Set{Input|Output}Filter directive now overrides a parent
3253 container's directive (e.g. SetInputFilter in <Directory /web/foo>
3254 will override any SetInputFilter directive in <Directory /web>.)
3255 This new syntax is more consistent with Add{Input|Output}Filter
3256 directives defined in mod_mime. Also cures a bug in prior releases
3257 where the Set{Input|Output}Filter directive would corrupt the
3258 global configuration if the multiple directives were nested.
3261 *) Cured what's ailed mime for quite some time. If an AddSomething
3262 was given in the configuration (Language, Charset, Handler or
3263 Encoding) Apache would set the content type as given by AddType,
3264 but refused to check the mime.types file if AddType wasn't given
3265 for that specific extension. Setting the AddHandler for .html
3266 without setting the AddType text/html html would cause Apache to
3267 use the default content type. [William Rowe]
3269 *) Added some bulletproofing to memory allocation in the LDAP cache
3270 code. [Graham Leggett]
3272 Changes with Apache 2.0.25
3274 *) Move the installed /manual directory out of the /htdocs/ tree, so
3275 that it can be kept more independently from the remaining document
3276 root. The "Alias /manual ..." already allowed for easy projection
3277 into existing private document trees. [Martin Kraemer]
3279 *) Add specified user attributes to the environment when using
3280 mod_auth_ldap. This allows you to use mod_include to embed specified
3281 user attributes in a page like so:
3282 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
3285 *) Fix a performance problem with the worker MPM. We now create
3286 transaction pools once, and re-use them for each connection.
3287 [Aaron Bannert <aaron clove.org>]
3289 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
3290 of a 'handler' or 'filter', so that any filename extension that does
3291 not contribute to the negotiated metadata can't be served without
3292 an explicit request. E.g., if the .Z extension is associated with
3293 an unzip filter, the user request somefile.Z.html, mod_negotiation
3294 won't serve it. It can serve somefile.Z.html when somefile.Z is
3295 requested, since the .Z extension is explictly requested, if the
3296 .html extension is associated with ContentType text/html.
3299 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
3300 and corresponding AddOutputFilter syntax, to insert one or more
3301 filters by mod_mime filename extension processing.
3304 *) Fix a growing connection pool in core_output_filter() for
3305 keepalive requests. [Jeff Trawick]
3307 *) Moved split_and_pass_pretag_buckets back to being a
3308 macro at Ryans's request. Removed the return from it
3309 by setting and returning a return code instead. Updated
3310 the code to check the return code from the macro and
3311 do the right thing. [Paul J. Reder]
3313 *) Fix a segfault when a numeric value was received for Host:.
3316 *) Add a function ap_remove_input_filter. This is to match
3317 up with ap_remove_output_filter. [Ryan Bloom]
3319 *) Clean up location_walk, so that this step performs a minimum
3320 amount of redundant effort (it must be run twice, but it will no
3321 longer reparse all <Location > blocks when the request uri
3322 hadn't changed.) [William Rowe]
3324 *) Eliminate proxy: (and all other 'special') processing from the
3325 ap_directory_walk() phase. Modules that want to use special
3326 walk logic should refer to the mod_proxy map_to_location example,
3327 with it's proxy_walk and proxysection implementation. This makes
3328 either directory_walk flavor much more legible, since that phase
3329 only runs against real <Directory > blocks.
3332 *) SECURITY: Fix a security problem in mod_include which would allow
3333 an SSI document to be passed to the client unparsed.
3334 [Cliff Woolley, Brian Pane]
3336 *) Introduce the map_to_storage hook, which allows modules to bypass
3337 the directory_walk and file_walk for non-file requests. TRACE
3338 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
3339 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
3342 *) Add the ability for mod_include to add the INCLUDES filter
3343 if the file is configured for the server-parsed handler.
3344 This makes the configuration for .shtml files much easier
3345 to understand, and allows mod_include to honor Apache 1.3
3346 config files. Based on Doug MacEachern's patch to PHP
3347 to do the same thing. [Ryan Bloom]
3349 *) force OpenSSL to ignore process local-caching and to always
3350 get/set/delete sessions using mod_ssl's callbacks
3351 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3352 Geoff Thorpe <geoff geoffthorpe.net>]
3354 *) Make the worker MPM shutdown and restart cleanly. This also
3355 cleans up some race conditions, and gets the worker using
3356 pools more cleanly. [Aaron Bannert <aaron clove.org>]
3358 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
3360 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3362 *) Fix for mod_include. Ryan's patch to check error
3363 codes put a return in the wrong place. Also, the
3364 include handler return code wasn't being checked.
3365 I don't like macros with returns, so I converted
3366 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
3367 [Paul J. Reder <rederpj raleigh.ibm.com>]
3369 *) fix segv in mod_mime if no AddTypes are configured
3370 [John Sterling <sterling covalent.net>]
3372 *) Enable ssl client authentication at SSL_accept time
3373 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3375 *) Fix a segfault in mod_include when the original request has no
3376 associated filename (e.g., we're filtering the error document for
3377 a bad URI). [Jeff Trawick]
3379 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
3381 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
3382 of httpd is started and shuts down due to socket conflict. Moving the
3383 call to ap_log_pid solves the problem.
3385 *) Changed the late-1.3 log_config substitution %c to %X, to log the
3386 status of the closed connection, as it conflicts with the far more
3387 common, historical ssl logging directive %...{var}c. [William Rowe]
3389 *) Added the common error/ tree to the build/install targets
3390 (similar to the common icons/ tree) for the multi-language error
3391 messages that Lars committed earlier. [William Rowe]
3393 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
3395 *) Added a default commented-out mod_ldap and mod_auth_ldap
3396 configuration to httpd-std.conf and httpd-win.conf
3399 *) Added documentation for mod_ldap and mod_auth_ldap.
3402 *) Enabled negative caching on attribute comparisons in the LDAP cache.
3403 Fixed a problem where the default cache TTL was set in milliseconds
3404 not microseconds causing the cache to time out almost immediately.
3407 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
3408 module code to follow APR. [Graham Leggett]
3410 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
3411 cleaned up when the connection pool pool is cleaned up.
3414 *) Fix a minor issue with Jeff Trawick's mod_include
3415 patch. Without this patch, the code will just allocate
3416 more bytes in get_combined_directive than are needed.
3419 *) Added the LDAP authentication module mod_auth_ldap.
3420 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3422 *) Added the LDAP cache and connection pooling module mod_ldap.
3423 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3425 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
3426 by allowing a module to disable itself if its prerequisites are not
3427 met. [Justin Erenkrantz]
3429 Changes with Apache 2.0.24
3431 *) Fix a couple of issues in mod_include when the tag appeared at
3432 offsets near 8192 in the file being parsed. [Jeff Trawick]
3434 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
3435 reached. [Jeff Trawick]
3437 *) Numerous improvements to the Win32 build system. Introduced command line
3438 builds without requiring .mak files for MSVC 6.0 and later versions.
3439 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
3442 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
3443 reporting of uninstalled services and other error conditions, and changed the
3444 default service name to Apache2. [William Rowe]
3446 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
3447 compatibility with existing Apache 1.3 Win32 Apache management utilites.
3448 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
3450 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
3451 [William Rowe, Greg Ames]
3453 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
3454 and RemoveCharset directives. [William Rowe]
3456 *) The Unix MPMs other than perchild now allow child server
3457 processes to use the accept mutex when starting as root and
3458 using SysV sems for the accept mutex. Previously, this
3459 combination would lead to fatal errors in the child server
3460 processes. perchild can't use SysV sems because of security
3461 issues. [Jeff Trawick, Greg Ames]
3463 *) Added Win32 revision stamp resources to all http binaries
3464 (including modules/ and support/ tools.) PR7322 [William Rowe]
3466 *) Fix ap_rvprintf to support more than 4K of data at one time.
3467 [Cody Sherr <csherr covalent.net>]
3469 *) We have always used the obsolete/deprecated Netscape syntax
3470 for our tracking cookies; now the CookieStyle directive
3471 allows the Webmaster to choose the Netscape, RFC2109, or
3472 RFC2965 format. The new CookieDomain directive allows the
3473 setting of the cookie's Domain= attribute, too. PR #s 5006,
3474 5023, 5920, 6140 [Ken Coar]
3476 *) Tweak server/Makefile so that the rules for generating exports.c
3477 are compatible with make utilities which don't expand wildcards
3478 in a dependency list (e.g., OS/390 make, certain levels of GNU
3479 make). [Jeff Trawick]
3481 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
3483 *) Begin to sanitize the MPM configuration directives. Now, all
3484 MPMs use the same functions for all common MPM directives. This
3485 should make it easier to catch all bugs in these directives once.
3486 [Cody Sherr <csherr covalent.net>]
3488 *) Close a major resource leak. Every time we had issued a
3489 graceful restart, we leaked a socket descriptor.
3492 *) Fix a problem with the new method code. We need to cast
3493 the 1 to an apr_int64_t or it will be treated as a 32-bit
3494 integer, and it will wrap after being shifted 32 times.
3495 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
3497 *) Fix a bug in mod_expires. Previous to this patch, if you
3498 told mod_expires to add 604800 seconds to the last-modified
3499 time, it actually added 604800 usec's to the last-modified time,
3500 so that when looking at the response it looked like nothing
3501 had been done. The root of the problem was that we always compute
3502 time in usec's, but we ask users to input sec's. This means we
3503 need to convert to usec's before using those values.
3506 *) The worker MPM now handles shutdown and restart requests. It
3507 definitely isn't perfect, but we do stop the servers correctly.
3508 The biggest problem right now is that SIGHUP causes the server to
3509 just die. [Ryan Bloom]
3511 Changes with Apache 2.0.23
3513 *) Use the prefork MPM by default on Unix. [various]
3515 *) Added a systray icon monitor application for Win32.
3516 [Mladen Turk <mturk mappingsoft.com>]
3518 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3519 messages written to the rewrite log.
3520 [Richard Labennett <rlabenn us.ibm.com>]
3522 *) All mod_autoindex query parsing is now quietly quashed with the
3523 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3524 still drops the column sort <a href>'s for the column headers, but
3525 IgnoreClient is required to ignore these Query options entirely.
3528 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3529 to allow the client to select plain, FancyIndexing or HTMLTable
3530 formatting, V=[0|1] to inhibit or enable version sorting, and
3531 P=pattern to return only specific files. The old Query Arguments
3532 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3533 as before), and O=A|D for ordering ascending or descending.
3536 *) Fixed an error in mod_include's directive parsing routines which
3537 caused #if, #elif, and #else expressions containing backslashes
3538 to be improperly evaluated. [Cliff Woolley]
3540 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3541 drop the icon column, SuppressRules to drop the <hr> elements,
3542 and HTMLTable to create rudimentary HTML table listings (implies
3543 FancyIndexing). [William Rowe]
3545 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3546 from Apache 1.3.15. This is needed for two reasons, first, given
3547 multiple machines within a server farm, ETags and Last-Modified
3548 stamps won't correspond from machine to machine, and second, many
3549 Unixes don't capture changes to the date or time stamp of existing
3550 files, since these don't modify the dirent itself. [William Rowe]
3552 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3553 and DirectoryWidth options from Apache 1.3.10.
3554 [William Rowe, Ken Coar]
3556 *) Eliminated FancyIndexing directive, deprecated early in Apache
3557 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3559 *) mod_autoindex now excludes any file names that would result in
3560 an error, other than a success or redirect. Also optimized
3561 the parent directory, always included except in the URI '/'.
3564 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3565 negotiated index pages, and prevent the server from defaulting
3566 to an autoindex of the directory. mod_negotiation will now die
3567 with a 500 Internal Error if it could match some filenames
3568 (e.g. for mod_dir) but none can be served. mod_negotation now
3569 refuses to serve any file with an extention that mod_mime doesn't
3570 recognize, and wasn't part of the request. [William Rowe]
3572 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3573 extension. This is already handled by multiviews, if the admin
3574 wishes to AddHandler .exe or define a content type handler and
3575 associate .exe files with that content type. Multiviews must be
3576 enabled to allow these to be served. [William Rowe]
3578 *) Speed up the server's response to a spike in incoming workload
3579 or restarts by assigning empty scoreboard slots to new processes
3580 when they are available. [Greg Ames]
3582 *) Add a handler to mod_includes.c. This handler is designed to
3583 implement the XbitHack directive. This can't be done with a
3584 fixup, because we need to check the content-type, which is
3585 only available in the handler phase. [Ryan Bloom]
3587 *) Make the includes filter check return codes from filters lower in
3588 the filter chain. If a lower level filter returns an error, then
3589 the request needs to stop immediately. This allows mod_include to
3590 stop parsing data once a lower filter recognizes an error.
3593 *) Add the ability to extend the methods that Apache understands
3594 and have those methods <limit>able in the httpd.conf. It uses
3595 the same bit mask/shifted offset as the original HTTP methods
3596 such as M_GET or M_POST, but expands the total bits from an int to
3597 an ap_int64_t to handle more bits for new request methods than
3598 an int provides. [Cody Sherr <csherr covalent.net>]
3600 *) Fix broken mod_mime behavior in merging its arguments. Possible
3601 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
3603 *) Solve many mod_ssl porting issues (too many to detail) with
3604 help from the whole team, but most notably [Ralf S. Engelschall,
3605 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3606 Doug MacEachern, William Rowe, Cliff Woolley]
3608 *) More stall fixes for the threaded & worker mpm's.
3609 Make mod_status output more accurate. Don't
3610 count workers in processes which aren't actively
3611 serving requests. [Greg Ames]
3613 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
3615 *) Add a single listener/multiple worker MPM. This MPM is
3616 definately not fully correct, but it allows us to solve many
3617 of the problems that exist in the threaded MPM. This is a
3618 modified version of the threaded MPM. [Ryan Bloom]
3620 *) Improve content generation throughout Apache, providing closer
3621 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
3622 Transitional specifications. [William Rowe]
3624 Changes with Apache 2.0.22
3626 *) Fix a problem where the threaded MPM stalls after restarts or
3627 segfaults. Also prevent multiple active processes from using
3628 the same scoreboard slot. [Greg Ames]
3630 *) Apache/Win32 now fills in the service description with Apache's
3631 server version string, including loaded and advertised modules.
3634 *) Improved support for the Win32 build, to recover gracefully from
3635 missing apr or apr-util directories or the awk interpreter,
3636 create the proper cgi-bin examples, including a test-cgi.bat, and
3637 fix the perl shebang line for printenv.pl, when installing from
3638 the build environment. [William Rowe]
3640 *) Fix a segfault in threaded.c caused by passing uninitialized
3641 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
3643 *) Use new APR number conversion functions to reduce CPU consumption
3644 when setting the content length, and in mod_log_config.
3647 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
3648 where HEAD response headers were being repeated twice for
3649 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
3650 problem in the http_header filter was exposed by the recent rewrite
3651 of the content_length filter. [Taketo Kabe, Bill Stoddard]
3653 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
3654 restarts. A garbage pointer to a vhost's server_rec from the
3655 previous generation was being left around under certain
3656 conditions. [Greg Ames]
3658 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
3659 used to appear as '(none', without the closing paren.
3660 [Günter Knauf <eflash gmx.net>]
3662 *) Improve the exports generating awk script. In the past, we had
3663 work around problems in the awk script by avoiding some #if and
3664 #ifdefs. This has bitten us many times in generating the exports.c
3665 file. This improvement allows corrects the header file parsing.
3666 [Sander Striker <striker apache.org>]
3668 Changes with Apache 2.0.21
3670 *) Resolve the Win32 htpasswd bug, where a file that existed would be
3671 overwritten, regardless of the -c flag.
3672 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
3674 *) Introduce connection sub-pools into ab. Truncating the lifetime
3675 of these allocations means that ab no longer perpetually grows
3676 its working set, running out of memory on large request attempts.
3679 *) Make scoreboard creation a hook. This allows management
3680 modules to have access to the scoreboard at the time that it is
3681 created, and at every restart request.
3682 [Cody Sherr <csherr covalent.net>]
3684 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
3685 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
3686 daemon index actually used in the scoreboard. I also
3687 updated the pertinent calls. [Paul J. Reder]
3689 *) Win32: Prevent listening sockets from being inherited by
3690 the Apache child process, CGI scripts, rotatelog process
3691 etc. If the Apache child process segfaults, any processes
3692 that the child started are not reaped. Prior to this fix,
3693 these processes inherited the listening sockets which sometimes
3694 prevented the restarted Apache child process from accepting
3695 connections (ie, the server would hang).
3698 *) Provide vhost and request strings when ExtendedStatus is on.
3701 *) Fix some issues with the pod and prefork: check the pod *after*
3702 processing a connection so that a server processing a time-
3703 consuming request bails out as soon as practical; when the
3704 parent process wakes up a server process via connect(), use an
3705 APR timeout on the connect() so that we don't hang for a long
3706 time if there aren't server processes around to do accept().
3707 [Jeff Trawick, Greg Ames]
3709 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
3710 spends a lot of time in apr_table_get calls. Using the default
3711 httpd.conf, the tables for languages and charsets are somewhat
3712 large, so the time spent scanning them on each request is
3713 significant. Replacing the tables with hash tables provides
3714 a nice speedup. [Brian Pane <bpane pacbell.net>]
3716 *) Add two functions to allow modules to access random parts of the
3717 scoreboard. This allows modules compiled for one MPM to access the
3718 scoreboard, even if it the server was compiled for another MPM.
3719 [Harrie Hazewinkel <harrie covalent.net>]
3721 Changes with Apache 2.0.20
3723 *) Fix problem in content-length filter where the filter would
3724 buffer all the output from a CGI before sending any bytes
3725 down the filter stack to the network. This problem would cause
3726 significant memory consumption if the CGIs generated
3727 lots of bytes. [Bill Stoddard]
3729 *) Get non-blocking CGI pipe reads working with the bucket brigades.
3732 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
3735 *) Fix a bug in the threaded MPM that would cause it to kill off all
3736 workers immediately after starting if the number of workers started
3737 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
3739 Changes with Apache 2.0.19
3741 *) Fix problem with threaded MPM. The problem was that if each child
3742 process was busy serving a single long-lived request and the server
3743 was sent a graceful restart signal, the server would stop serving
3744 requests. This would happen because each child process would wait to
3745 die until the last thread was done, and the parent wouldn't spawn any
3746 new children until a process died. Now, the parent looks at the fact
3747 that the children are dying gracefully, and starts new children.
3748 Those new children only start enough threads to compliment the number
3749 of threads in the other child process that shares the same spot in
3750 the scoreboard. In this way, we make sure to never go over
3751 MaxClients. [Ryan Bloom]
3753 *) modified mod_negotiation and mod_autoindex to speed up by almost a
3754 factor of two on apr_dir_read()-enhanced platforms, such as Win32
3755 and OS2, by calling ap_sub_request_lookup_dirent() with the results
3756 already provided by apr_dir_read(). [William Rowe]
3758 *) mod_file_cache is now more robust to filtering and serves requests
3759 slightly more efficiently. [Cliff Woolley]
3761 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
3762 Module was calling ap_rwrite() followed by ap_rflush() but the
3763 served content was not being displayed in the browser. Inspection
3764 of the output stream revealed that the first data chunk was
3765 missing the trailing CRLF required by the RFC. [Bill Stoddard]
3767 *) apxs no longer generates ap_send_http_header() in the example handler
3769 *) Fix an ab problem which could cause a divide-by-zero exception
3770 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
3771 [Ian Holsman <ianh cnet.com>]
3773 *) Solve case-insensitive platforms' confusion about negotiated
3774 filenames, allowing files of differnt case to match in choosing
3775 the document to serve. [William Rowe]
3777 *) Fix brokenness when ThreadsPerChild is higher than the built-in
3778 limit. We left ap_threads_per_child at the higher value which
3779 led to segfaults when doing certain scoreboard operations.
3782 *) Fix seg faults and/or missing output from mod_include. The
3783 default_handler was using the subrequest pool for files and
3784 MMAPs, even though the associated APR structures typically
3785 live longer than the subrequest. [Greg Ames]
3787 *) Extend mod_setenvif to support specifying regular expressions
3788 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
3789 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
3790 will cause HAVE_TS to be set if any of the request headers begins
3791 with "TS" and has a value that begins with any character in the
3792 set [a-z]. [Bill Stoddard]
3794 *) httpd children now re-bind themselves to a random CPU on
3795 multiprocessor systems on AIX via bindprocessor() in 2.0.
3796 [Victor J. Orlikowski]
3798 *) Fix htdigest. It would go into a loop in getline when adding
3799 a second user. [Bill Stoddard]
3801 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
3803 *) Automatically generate httpd.exp for AIX.
3804 DSOs now work again on AIX in 2.0
3805 [Victor J. Orlikowski]
3807 *) Add a new request hook, error_log. This phase allows modules
3808 to act on the error log string _after_ it has been written
3809 to the error log. The goal for this hook is to allow monitoring
3810 modules to send the error string to the monitoring agent.
3813 *) Modify mod_echo to make it use filters for input and output.
3814 [Ryan Morgan <rmorgan covalent.net>]
3816 *) Extend mod_headers to support conditional driven Header
3817 add, append and set. Use SetEnvIf to set an envar and conditionally
3818 add/append/set headers based on this envar thusly:
3820 SetEnvIf TSMyHeader value HAVE_TSMyHeader
3821 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
3823 If the request contains header "TSMyHeader: value" then header
3824 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
3827 *) Extend mod_headers to support using format specifiers on Header
3828 add, append and set header values. Two format specifiers are supported:
3830 %t - reports, in UTC microseconds since the epoch, when the
3831 request was received.
3833 %D - reports the time, in microseconds, between when the request was
3834 received and the response sent.
3837 Header add MyHeader "This request served in %D microseconds. %t"
3839 results in a header being added to the response that looks like this:
3841 MyHeader: This request served in D=5438 microseconds. t=991424704447256
3845 *) Fix reset_filter(). We need to be careful how we remove filters.
3846 If we set r->output_filters to NULL, we also have to reset the
3847 connection's filters. [John Sterling]
3849 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
3851 *) Add a check to ap_die() to make sure the filter stack is sane and
3852 contains the correct basic filters when an error occurs. This fixes
3853 a problem where headers are not being sent on error. [John Sterling]
3855 *) New Header directive 'echo' option. "Header echo regex" will
3856 cause any headers received on the request that match regex to be
3857 echoed to (included in) the response headers.
3860 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
3861 This prevented the inclusion of apr_compat.h. PR #7773
3862 [Oleg Broytmann <phd phd.pp.ru>]
3864 *) Moved util_uri to the apr-util library. This required a bunch of
3865 apr_name changes for the uri utility functions. [Justin Erenkrantz]
3867 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
3868 insert_filter phase so that other filters are not bypassed by default.
3871 *) Reimplement mod_headers as an output filter. mod_headers can now
3872 add custom headers to inbound requests using the RequestHeader directive
3873 and to responses using the same old Header directive. [Graham Leggett]
3875 Changes with Apache 2.0.18
3877 *) Fix command-line processing so that if a bad argument is specified
3878 Apache will exit. [Jeff Trawick]
3880 *) Change the make targets and rules to be consistent in all of the
3881 Apache-owned source trees. [Roy Fielding]
3883 *) Fix processing of the TRACE method. Previously we passed bogus
3884 parms to form_header_field() and it overlaid some vhost structures,
3885 resulting in a segfault in check_hostalias().
3886 [Greg Ames, Jeff Trawick]
3888 *) Win32: Add support for reliable piped logs. If the logging process
3889 goes down, Apache will automatically restart it. This function has
3890 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
3893 *) Do not start piped log processes during the config file
3894 preflight. This change also circumvents a problem on
3895 Windows where the rotatelog processes created during preflight
3896 was not getting cleaned up properly.
3899 *) add "Request Phase Participation" info to mod_info
3902 *) Make first phase changes to the scoreboard data structures in
3903 preparation for the rewriting of the scoreboard per my posted
3904 design notes. [Paul J. Reder]
3906 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
3907 and apr-util, allow it to be overridden by the configure command-line
3908 (default="--silent") and introduce LT_LDFLAGS to replace what we were
3909 formerly abusing as LTFLAGS. [Roy Fielding]
3911 *) Clean up the reporting of incorrect closing container tags.
3912 [Barrie Slaymaker <barries slaysys.com>]
3914 *) Simplify the configure process by moving all libtool stuff to APR
3915 and moving hints.m4 inline. [Roy Fielding]
3917 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
3918 of functions used by mod_proxy for export in the DLL
3919 [Ian Holsman <IanH cnet.com>]
3921 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
3922 request body from its stdin but no reqest body is being written to
3923 the cgi. [Jeff Trawick]
3925 *) mod_log_config: %c connection status incorrectly logged
3926 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
3929 *) Get mod_cern_meta working under Windows
3932 *) Create Files, and thus MMAPs, out of the request pool, not the
3933 connection pool. This solves a small resource leak that had us
3934 not closing files until a connection was closed. In order to do
3935 this, at the end of the core_output_filter, we loop through the
3936 brigade and convert any data we have into a single HEAP bucket
3937 that we know will survive clearing the request_rec.
3938 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
3941 *) Completely revamp configure so that it preserves the standard make
3942 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
3943 the configure additions to EXTRA_* variables. Also, allow the user
3944 to specify NOTEST_* values for all of the above, which eliminates the
3945 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
3946 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
3947 avoid pointless duplications. Fix the order in which flags are given
3948 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
3949 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
3950 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
3951 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
3953 *) Get mod_tls to compile/work better on Windows. PR #7612
3954 [Bernhard Schrenk <b.schrenk improx.com>]
3956 *) Fix shutdown/restart hangs in the threaded MPM.
3957 [Jeff Trawick, Greg Ames, Ryan Bloom]
3959 *) Removed the keptalive boolean from conn_rec because it is now only
3960 used by a single routine and can be replaced by a local variable.
3961 [Greg Stein, Ryan Bloom, Roy Fielding]
3963 *) Patch prefork to put enough of the signal processing back in so that
3964 signals are all handled properly now. The previous patch fixed the
3965 deadlock race condition, but broke the user directed signal handling.
3966 This fixes it to work the way it did before my previous prefork patch
3967 (primarily, SIGTERM is now working).
3969 *) Change how input filters decide how much data is returned to the
3970 higher filter. We used to use a field in the conn_rec, with this
3971 change, we use an argument to ap_get_brigade to determine how much
3972 data is retrieved. [Ryan Bloom]
3974 *) Fix seg fault at start-up introduced by Ryan's change to enable
3975 modules to specify their own logging tags. mod_log_config
3976 registers an optional function, ap_register_log_handler().
3977 ap_register_log_handler() was being called by http_core before
3978 the directive hash table was created. This patch creates the
3979 directive hash table before ap_register_log_handler() is
3980 registered as an optional function.
3981 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
3983 *) Add ap_set_int_slot() function
3984 [John K. Sterling <sterling covalent.net>]
3986 *) Under certain circumstances, Apache did not supply the
3987 right response headers when requiring authentication.
3988 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
3989 (This is a port of the change that went into Apache 1.3.19.)
3991 *) Allow modules to specify their own logging tags. This basically
3992 allows a module to tell mod_log_config that when %x is encountered
3993 a specific function should be called. Currently, x can be any single
3994 character. It may be more useful to make this a string at some point.
3997 Changes with Apache 2.0.17
3999 *) If a higher-level filter handles the the byterange aspects of a
4000 request, then the byterange filter should not try to redo the
4001 work. The most common case of this happening, is a byterange
4002 request going through the proxy, and the origin server handles
4003 the byterange request. The proxy should ignore it.
4004 [Graham Leggett <minfrin sharp.fm>]
4006 *) Changed the threaded mpm to have child_main join to each of the
4007 worker threads to make sure the kids are all gone before child_main
4008 exits after a signal (cleanup from perform_idle_server_maintenance).
4009 This is an extension of Ryans recent commit to make the child_main
4012 *) Add more options to the ap_mpm_query function. This also allows MPMs to
4013 report if their threads are dynamic or static. Finally, this also
4014 implements a new API, ap_show_mpm, which returns the MPM that was
4015 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
4017 *) Do not install the binaries from the support directory twice.
4018 [jun-ichiro hagino <itojun iijlab.net>]
4020 *) The ap_f* functions should flush data to the filter that is passed
4021 in, not the the filter after the one passed in.
4022 [Ryan Morgan <rmorgan covalent.net>]
4024 *) Make ab work again by changing its native types to apr types and formats.
4025 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4027 *) Move the byterange filter and all of the supporting functions back
4028 to the HTTP module. The byterange filter turned out to be very
4029 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
4031 *) Make clean, distclean, and extraclean consistently according to the
4032 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4034 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
4035 This may have been causing problems stopping processes in the threaded
4038 *) Fix content-length in mod_negotiation to a long int representation.
4041 *) Remove BindAddress from the default config file.
4042 [<giles nemeton.com.au>]
4044 *) Allow module authors to add a module to their Apache build using
4045 --with-module, without re-running buildconf. The syntax is:
4046 --with-module=module_type:/path/to/module.c
4047 The configure script will copy the module.c file to
4048 modules/module_type, and it will be added to the relevant Makefiles.
4049 currently, this only works for static modules. [Ryan Bloom]
4051 *) Changes required to make prefork clean up idle children properly.
4052 There was a window during which a starting worker deadlocks when
4053 an idle cleanup arrives before it completes init. Apache then keeps
4054 trying to cleanup the same deadlocked worker forever (until higher
4055 pids come along, but it still will never reduce below the deadlocked
4056 pid). Thus the number of children would not reduce to the correct
4057 idle level. [Paul J. Reder]
4059 Changes with Apache 2.0.16
4061 *) Change the default installation directory to /usr/local/apache2,
4062 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
4064 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
4067 *) Get MaxRequestsPerChild working with the Windows MPM.
4070 *) Make generic hooks to work, with mod_generic_hook_import/export
4071 experimental modules. [Ben Laurie, Will Rowe]
4073 *) Fix segfaults for configuration file syntax errors such as
4074 "<Directory>" followed by "</Directory" and
4075 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
4077 *) Cleanup the --enable-layout option of configure. This makes
4078 us use a consistent location for the config.layout file, and it
4079 makes configure more portable.
4080 [jun-ichiro hagino <itojun iijlab.net>]
4082 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
4083 csv/gnuplot format, rudimentary ssl support and various other tweaks
4084 to make results more true to what is measured. The upshot of this it
4085 turns out that 'ab' has often underreported the true performance of
4086 apache. Often by a order of magnitude :-) See talk/paper of Sander
4087 Temme at April ApacheCon 2001 for details.
4088 [Dirk-Willem van Gulik]
4090 *) Clean up mod_cgid's temporary request pool. Besides fixing a
4091 storage leak this ensures that some unnecessary pipes are closed.
4094 *) Performance: Add quick_handler hook. This hook is called at the
4095 very beginning of the request processing before location_walk,
4096 translate_name, etc. This hook is useful for URI keyed content
4097 caches like Mike Abbott's Quick Shortcut Cache.
4100 *) top_module global variable renamed to ap_top_module [Perl]
4102 *) Move ap_set_last_modified to the core. This is a potentially
4103 controversial change, because this is kind of HTTP specific. However
4104 many protocols should be able to take advantage of this kind of
4105 information. I expect that headers will need one more layer of
4106 indirection for multi-protocol work, but this is a small step in
4107 the right direction. [Ryan Bloom]
4109 *) Enable mod_status by default. This matches what Apache 1.3 does.
4112 *) Add a ScriptSock directive to the default config file. This is
4113 only enabled when mod_cgid is used.
4114 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4116 Changes with Apache 2.0.15
4118 *) Untangled the buildconf script and eliminated the need for build's
4119 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
4120 libtool muck that is now under srclib/apr/build. [Roy Fielding]
4122 *) Win32: Don't accept more connections than we have worker threads
4126 *) Fix bug in the Unix threaded.c MPM that allowed child processes
4127 to fork() new child processes.
4130 *) SECURITY: Fix a major security problem with double-reverse lookup
4131 checking. Previously, a client connecting over IPv4 would not be
4132 matched properly when the server had an IPv6 listening socket.
4133 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
4135 *) Change the way the beos MPM handles polling to allow it to stop and
4136 restart. Problem was the sockets being polled were being reset by
4137 the select call, so once it had accepted a connection it was no
4138 longer listening on the UDP socket we use for shutdown instructions.
4139 APR needs to be altered, patch on it's way. [David Reid]
4141 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
4142 on error exit from ap_getline(). Some other code got upset because
4143 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
4145 *) Handle ap_discard_request_body() being called more than once.
4146 [Greg Ames, Jeff Trawick]
4148 *) Get rid of an inadvertent close of file descriptor 2 in
4149 mod_mime_magic. [Greg Ames, Jeff Trawick]
4151 *) Add a hook, create_request. This hook allows modules to modify
4152 a request while it is being created. This hook is called for all
4153 request_rec's, main request, sub request, and internal redirect.
4154 When this hook is called, the the r->main, r->prev, r->next
4155 pointers have been set, so modules can determine what kind of
4156 request this is. [Ryan Bloom]
4158 *) Cleanup the build process a bit more. The Apache configure
4159 script no longer creates its own helper scripts, it just
4161 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4163 *) Stop the forced downgrade of the connection to HTTP/1.0 for
4164 proxy requests. [Graham Leggett]
4166 *) Avoid using sscanf to determine the HTTP protocol number in
4167 the common case because sscanf is a performance hog. From
4168 Mike Abbot's Accelerating Apache patch number 6.
4169 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
4171 *) SECURITY: Fix a security exposure in mod_access. Previously when
4172 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
4173 were not evaluated properly (PR #7407). Also, add the ability to
4174 specify IPv6 address strings with optional prefix length on Allow
4175 and Deny. [Jeff Trawick]
4177 *) Enhance rotatelogs so that a UTC offset can be specified, and
4178 the logfile name can be formatted using strftime(3). (Brought
4179 forward from 1.3.) [Ken Coar]
4181 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
4182 DuplicateHandle on an IOCompletionPort (a practice which
4183 MS "discourages"). The new model does not rely on associating
4184 the completion port with the listening sockets, thus the
4185 completion port can be completely managed within the child
4186 process. A dedicated thread accepts connections off the network,
4187 then calls PostQueuedCompletionStatus() to wake up worker
4188 threads blocked on the completion port.
4191 *) Bring forward the --suexec-umask option which allows the
4192 builder to preset the umask for suexec processes. [Ken Coar]
4194 *) Add a -V flag to suexec, which causes it to display the
4195 compile-time settings with which it was built. (Only
4196 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
4198 *) Mod_include should always unset the content-length if the file is
4199 going to be passed through send_parsed_content. There is no to
4200 determine if the content will change before actually scanning the
4201 entire content. It is far safer to just remove the C-L as long
4202 as we are scanning it. [Ryan Bloom]
4204 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
4205 request and not Proxy-Authenticate.
4206 [Graham Leggett <minfrin sharp.fm>]
4208 Changes with Apache 2.0.14
4210 *) Fix content-length computation. We ONLY compute a content-length if
4211 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
4212 or we already have all the data. [Ryan Bloom]
4214 *) Report unbounded containers in the config file. Previously, a typo
4215 in the </container> directive could result in the rest of the config
4216 file being silently ignored, with undesired defaults used.
4219 *) Make the old_write filter use the ap_f* functions for the buffering.
4222 *) Move more code from the http module into the core server. This
4223 is core code, basically the default handler, the default input
4224 and output filters, and all of the core configuration directives.
4225 All of this code is required in order for the server to work, with or
4226 without HTTP. The server is closer to working without the HTTP
4227 module, although there is still more to do. [Ryan Bloom]
4229 *) Fix a number of SGI compile warnings throughout the server. Fix some
4230 bad parameters to apr_bucket_read(). Fix a bad statement in
4231 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
4232 consistently; we were mixing apr_time_t and time_t in invalid ways
4233 before. In load_file(), call apr_dso_error() instead of
4234 apr_strerror() so that we get a more specific string on some platforms.
4235 PR #6980 [Jeff Trawick]
4237 *) Allow modules to query the MPM about it's execution profile. This
4238 query API can and should be extended in the future, but for now,
4239 max_daemons, and threading or forking is a very good start.
4240 [Jon Travis <jtravis covalent.net>]
4242 *) Modify mod_include to send blocks of data no larger than 9k.
4243 Without this, mod_include will wait until the whole file is parsed,
4244 or the first tag is found to send any data to the client.
4245 [Paul J. Reder <rederpj raleigh.ibm.com>]
4247 *) Fix mod_info, so that <Directory> and <Location> directives are
4248 not displayed twice when displaying the current configuration.
4249 [Ryan Morgan <rmorgan covalent.net>]
4251 *) Add config directives to override DEFAULT_ERROR_MSG and
4252 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
4253 [Dan Rench <drench xnet.com>]
4255 *) Get mod_info building and loading on Win32. [William Rowe]
4257 *) Begin to move protocol independant functions out of mod_http. The goal
4258 is to have only functions that are HTTP specific in the http directory.
4261 Changes with Apache 2.0.13
4263 *) Don't assume that there will always be multiple calls to the byterange
4264 filter. It is possible that we will need to do byteranges with only
4265 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
4267 *) Move the error_bucket definition from the http module to the
4268 core server. Every protocol will need this ability, not just
4271 Changes with Apache 2.0.12
4273 *) Modify mod_file_cache to save pre-formatted strings for
4274 content-length and last-modified headers for performance.
4275 [Mike Abbot <mja trudge.engr.sgi.com>]
4277 *) Namespace protect IOBUFSIZ since it is exposed in the API.
4278 [Jon Travis <jtravis covalent.net>]
4280 *) Use "Basic" authentication instead of "basic" in ab, as the spec
4281 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
4283 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
4284 without ever filling it out. This fixes PR 7271.
4285 [Taketo Kabe <kabe sra-tohoku.co.jp> and
4286 Cliff Woolley <cliffwoolley yahoo.com>]
4288 *) Add a couple of GCC attribute tags to printf style functions.
4289 [Jon Travis <jtravis covalent.net>]
4291 *) Add the correct language tag for interoperation with the Taiwanese
4292 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
4294 *) Migrate the perchild MPM to use the new apr signal child, and
4295 APR thread functions. [Ryan Bloom]
4297 *) Close one copy of the CGI's stdout before creating the new process.
4298 The CGI will still have stdout, because we have already dup'ed it.
4299 This keeps Apache from waiting forever to send the results of a CGI
4300 process that has forked a long-lived child process.
4301 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4303 *) Remove the rest of the pthreads functions from the threaded MPM.
4304 This requires the APR support for a signal thread that was just
4307 *) Make mod_dir use a fixup for sending a redirect to the browser.
4308 Before this, we were using a handler, which doesn't make much
4309 sense, because the handler wasn't generating any data, it would
4310 either return a redirect error code, or DECLINED. This fits the
4311 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
4313 *) Make the threaded MPM use APR threads instead of pthreads.
4316 *) Get mod_tls to the point where it actually appears to work in all cases.
4319 *) implement --enable-modules and --enable-mods-shared for "all" and
4320 "most". [Greg Stein]
4322 *) Move the threaded MPM to use APR locks instead of pthread locks.
4325 *) Rename mpmt_pthread to threaded. This is more in line with the
4326 fact that mpmt_pthread shouldn't be using pthreads directly, and
4327 it is a smaller name that doesn't tie into anything.
4330 *) Rename the module structures so that the exported symbol matches
4331 the file name, and it is easier to automate the installation
4332 process (generating LoadModule directives from the module filenames).
4335 *) Remove the coalesce filter. With the ap_f* functions, this filter
4336 is no longer needed. [Ryan Bloom]
4338 Changes with Apache 2.0.11
4340 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
4341 added feature of allowing a uid/gid per child process. If no
4342 uid/gid is specified, then Perchild behaves exactly like dexter.
4345 *) Get perchild building again. [Ryan Bloom]
4347 *) Don't disable threads just because we are using the prefork MPM.
4348 If somebody wants to compile without threads, they must now add
4349 --disable-threads to the configure command line. [Ryan Bloom]
4351 *) Begin to move the calls to update_child_status into common code, so
4352 that each individual MPM does not need to update the scoreboard itself.
4355 *) Allow mod_tls to compile under Unix boxes where openssl has been
4356 installed to the system include files.
4357 [Gomez Henri <new-httpd slib.fr>]
4359 *) Cleanup the mod_tls configure process. This should remove any need
4360 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
4361 configure doesn't check that yet. [Ryan Bloom]
4363 *) Add a very early prototype of SSL support (in mod_tls.c). It is
4364 vital that you read modules/tls/README before attempting to build
4367 *) Fix a potential seg fault on all platforms. David Reid fixed this
4368 on BEOS, but the problem could happen anywhere, so we don't want
4369 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
4371 *) Add new LogFormat directive, %D, to log time it takes to serve a
4372 request in microseconds. [Bill Stoddard]
4374 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
4375 SetOutputFilter. This corresponds nicely with the other Set
4376 directives, which operate on containers while the Add* directives
4377 tend to work directly on extensions. [Ryan Bloom]
4379 *) Cleanup the header handling a bit. This uses the apr_brigade_*
4380 functions for the buffering so that we don't need to compute
4381 the length of the headers before we actually create the header
4382 buffer. [Ryan Bloom]
4384 *) Allow filters to buffer data using the ap_f* functions. These have
4385 become macros that resolve directly to apr_brigade_*.
4388 *) Get the Unix MPM's to do a graceful restart again. If we are going
4389 to register a cleanup with ap_cleanup_scoreboard, then we have to
4390 kill the cleanup with the same function, and that function can't be
4391 static. [Ryan Bloom]
4393 *) Install all required header files. Without these, it was not
4394 possible to compile some modules outside of the server.
4397 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
4398 forward from 1.3 to 2.0, we missed a single line, which broke regex
4399 aliases. [Ryan Bloom]
4401 *) We have a poor abstraction in the protocol. This is a temporary
4402 hack to fix the bug, but it will need to be fixed for real. If
4403 we find an error while sending out a custom error response, we back
4404 up to the first non-OK request and send the data. Then, when we send
4405 the EOS from finalize_request_protocol, we go to the last request,
4406 to ensure that we aren't sending an EOS to a request that has already
4407 received one. Because the data is sent on a different request than
4408 the EOS, the error text never gets sent down the filter stack. This
4409 fixes the problem by finding the last request, and sending the data
4410 with that request. [Ryan Bloom]
4412 *) Make the server status page show the correct restart time, and
4413 thus the proper uptime. [Ryan Bloom]
4415 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
4416 should reduce the amount of duplicate code that is required to
4417 create CGI processes.
4418 [Paul J. Reder <rederpj raleigh.ibm.com>]
4420 *) ap_new_connection() closes the socket and returns NULL if a socket
4421 call fails. Usually this is due to a connection which has been
4422 reset. [Jeff Trawick]
4424 *) Move the Apache version information out of httpd.h and into release.h.
4425 This is in preparation for the first tag with the new tag and release
4426 system. [Ryan Bloom]
4428 *) Begin restructuring scoreboard code to enable adding back in
4429 the ability to use IPC other than shared memory.
4430 Get mod_status working on Windows again. [Bill Stoddard]
4432 *) Make mod_status work with 2.0. This will work for prefork,
4433 mpmt_pthread, and dexter. [Ryan Bloom]
4435 *) Correct a typo in httpd.conf.
4436 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
4438 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
4440 *) Get the correct IP address if ServerName isn't set and we can't
4441 find a fully-qualified domain name at startup.
4442 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
4444 *) Make mod_cgid work with SuExec. [Ryan Bloom]
4446 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
4447 'extra' stat's for user/group since they should never occur, and now
4448 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
4449 volumes. [William Rowe]
4451 *) Adopt apr features to simplify mod_includes. This changes the
4452 behavior of the USER_NAME variable, unknown uid's are now reported
4453 as USER_NAME="<unknown>" rather than the old user#000 result.
4454 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
4456 *) Adopt apr features for simplifing mod_userdir, and accept the new
4457 Win32/OS2 exceptions without hiccuping. [William Rowe]
4459 *) Replace configure --with-optim option by using and saving the
4460 environment variable OPTIM instead. This is needed because configure
4461 options do not support multiple flags separated by spaces.
4464 *) Fix some byterange handling. If we get a byte range that looks like
4465 "-999999" where that is past the end of the file, we should return
4466 a PARTIAL CONTENT status code, and return the whole file as one big
4467 byterange. This matches the 1.3 handling now. [Ryan Bloom]
4469 *) Make the error bucket a real meta-data bucket. This means that the
4470 bucket length is 0, and a read returns NULL data. If one of these
4471 buckets is passed down after the headers are sent, this data will
4472 just be ignored. [Greg Stein]
4474 *) The prefork MPM wasn't killing child processes correctly if a restart
4475 signal was received while the process was serving a request. The child
4476 process would become the equivalent of a second parent process. If
4477 we break out of the accept loop, then we need to do die after cleaning
4478 up after ourselves. [Ryan Bloom]
4480 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
4481 restarts. [Ryan Bloom]
4483 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
4484 the most optimal APR_FINFO_wanted bits. This spares Win32 from
4485 performing very expensive owner, group and permission lookups
4486 and allows the server to function until these apr_finfo_t fields
4487 are implemented under Win32. [William Rowe]
4489 *) Support for typedsafe optional functions - that is functions exported by
4490 optional modules, which, therefore, may or may not be present, depending
4491 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
4492 for sample code. [Ben Laurie]
4494 *) filters can now report an HTTP error to the server. This is done
4495 by sending a brigade where the first bucket is an error_bucket.
4496 This bucket is a simple bucket that stores an HTTP error and
4497 a string. Currently the string is not used, but it may be needed
4498 to output an error log. The http_header_filter will find this
4499 bucket, and output the error text, and then return
4500 AP_FILTER_ERROR, which informs the server that the error web page
4501 has already been sent. [Ryan Bloom]
4503 *) If we get an error, then we should remove all filters except for
4504 those critical to serving a web page. This fixes a bug, where
4505 error pages were going through the byterange filter, even though
4506 that made no sense. [Ryan Bloom]
4508 *) Relax the syntax checking of Host: headers in order to support
4509 iDNS. PR#6635 [Tony Finch]
4511 *) Cleanup the byterange filter to use the apr_brigade_partition
4512 and apr_bucket_copy functions. This removes a lot of very messy
4513 code, and hopefully makes this filter more stable.
4516 *) Remove AddModule and ClearModuleList directives. Both of these
4517 directives were used to ensure that modules could be enabled
4518 in the correct order. That requirement is now gone, because
4519 we use hooks to ensure that modules are in the correct order.
4522 *) When SuExec is specified, we need to add it to the list of
4523 targets to be built. If we don't, then any changes to the
4524 configuration won't affect SuExec, unless 'make suexec' is
4525 specifically run. [Ryan Bloom]
4527 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4528 the APR_XTHREAD argument to open a file for consumption by
4529 parallel threads on win32. [William Rowe]
4531 *) Correct a bug in determining when we follow symlinks. The code
4532 expected a stat -1 result, not an apr_status_t positive error.
4533 Also check if the APR_FINFO_USER fields are valid before we
4534 follow the link. [William Rowe]
4536 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4537 mpm_common.c. These functions are only valid on some platforms,
4538 so they should not be in the main-line code. [Ryan Bloom]
4540 *) Remove ap_chdir_file(). This function is not thread-safe,
4541 and nobody is currently using it. [Ryan Bloom]
4543 *) Do not try to run make depend if there are no .c files in the
4544 current directory, doing so makes `make depend` fail.
4547 *) Update highperformance.conf to work with either prefork or
4548 pthreads mpms. [Greg Ames]
4550 *) Stop checking to see if this is a pipelined request if we know
4551 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4552 This keeps us from making an extra read call when serving a 1.0
4553 request. [Ryan Bloom and Greg Stein]
4555 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4556 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4557 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4559 *) Fix the RFC number mentioned when complaining about a missing
4560 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
4562 *) Fix an endless loop in ab which occurred when ab was posting
4563 and the server dropped the connection unexpectedly.
4566 *) Fix a segfault while handling request bodies in ap_http_filter().
4567 This problem has been seen with mod_dav usage as well as with
4568 requests where the body was just being discarded. [Jeff Trawick]
4570 *) Some adjustment on the handling and automatic setting (via
4571 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4572 add the capability to specify flags (NOTEST_CFLAGS and
4573 NOTEST_LDFLAGS) which are used to compile Apache, but
4574 not used during the configuration process. Useful for
4575 flags like "-Werror". [Jim Jagielski]
4577 *) Stop using environment variables to force debug mode or
4578 no detach. We now use the -D command line argument to
4579 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4580 [Greg Stein, Ryan Bloom]
4582 *) Change handlers to use hooks. [Ben Laurie]
4584 *) Stop returning copies of filenames from both apr_file_t and
4585 apr_dir_t. We pstrdup the filenames that we store in the
4586 actual structures, so we don't need to pstrdup the strings again.
4589 *) mod_cgi: Fix some problems where the wrong error value was being
4590 traced. [Jeff Trawick]
4592 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
4595 *) Add generic hooks. [Ben Laurie]
4597 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
4599 *) Fix a segfault caused by mod_ext_filter when the external filter
4600 program does not exist. [Jeff Trawick]
4602 *) Fix an output truncation error when on an HTTP >= 1.0 request an
4603 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
4604 was served through mod_charset_lite (or anything else that would
4605 create a transient bucket in this size range). ap_bucket_make_heap()
4606 silently failed (fixed), transient_setaside() discovered it, but
4607 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
4609 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
4610 is that some browsers send extra lines at the end of POST requests, and
4611 we don't want to delay sending data back to the user just because the
4612 browser isn't well behaved. [Ryan Bloom]
4614 *) Get SuEXEC working again. We can't send absolute paths to suExec
4615 because it refuses to execute those programs. SuEXEC also wasn't
4616 always recognizing configuration changes made using the autoconf
4619 *) Allow the buildconf process to find the config.m4 files in the correct
4620 order. Basically, we can now name config.m4 files as config\d\d.m4,
4621 and we will sort them correctly when inserting them into the build
4622 process. [Ryan Bloom]
4624 *) Get mod_cgid to use apr calls for creating the actual CGI process.
4625 This also allows mod_cgid to use ap_os_create_priviledged_process,
4626 thus allowing for SuExec execution from mod_cgid. Currently, we do
4627 not support everything that standard SuExec supports, but at least
4628 it works minimally now. [Ryan Bloom]
4630 *) Allow SuExec to be configured from the ./configure command line.
4633 *) Update some of the docs in README and INSTALL to reflect some of
4634 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
4636 *) If we get EAGAIN returned from the call to apr_sendfile, then we
4637 need to call sendfile again. This gets us serving large files
4638 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
4640 *) Get the support programs building cleanly again.
4641 [Cliff Woolley <cliffwoolley yahoo.com>]
4643 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
4644 current directory logic now backs up over bin/ to determine the
4645 server root from the Apache.exe path.
4647 *) Apache/Win32 now follows the standard conventions of mod_foo.so
4648 loadable modules, dynamic libs are all named libfoo.dll, and the
4649 makefile.win populates the include, lib and libexec directories.
4651 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
4652 Apache gets IPv6 listening sockets by default. Additionally, the
4653 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
4654 numeric address strings (e.g., "Listen [fe80::1]:8080").
4657 *) Modify the install directory layout. Modules are now installed in
4658 modules/. Shared libraries should be installed in libraries/, but
4659 we don't have any of those on Unix yet. All install directories
4660 are modifyable at configure time. [Ryan Bloom]
4662 *) Install all header files in the same directory on Unix. [Ryan Bloom]
4664 *) Get the functions in server/linked into the server, regardless of
4665 which modules linked into the server. This uses the same hack
4666 for Apache that we use for APR and apr-util to ensure all of the
4667 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
4668 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
4669 the scripts a bit easier.
4672 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
4673 on the query, and remove IPv4 dependencies. [Jeff Trawick]
4675 *) Get all of the auth modules to the point that they will install and
4676 be loadable into the server. Our new build/install mechanism expects
4677 that all modules will have a common name format. The auth modules
4678 didn't use that format, so we didn't install them properly.
4681 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
4682 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
4684 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
4686 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
4687 after the end of the response. [Ryan Bloom]
4689 *) Get byterange requests working with responses that do not have a
4690 content-length. Because of the way byterange requests work, we have to
4691 have all of the data before we can actually do the byterange, so we
4692 can compute the content-length in the byterange filter.
4695 *) Get exe CGI's working again on Windows.
4698 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
4699 they keep track of whether or not their post config hook has been
4700 called before. Instead of a static variable (which is replaced when
4701 the DSO is loaded a second time), use userdata in the process pool.
4704 Changes with Apache 2.0a9
4706 *) Win32 now requires perl to complete the final install step for users
4707 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
4708 and installs the conf, htdocs and htdocs/manual directories.
4711 *) Make mod_include use a hash table to associate directive tags with
4712 functions. This allows modules to implement their own SSI tags easily.
4713 The idea is simple enough, a module can insert it's own tag and function
4714 combination into a hash table provided by mod_include. While mod_include
4715 parses an SSI file, when it encounters a tag in the file, it does a
4716 hash lookup to find the function that implements that tag, and passes
4717 all of the relevant data to the function. That function is then
4718 responsible for processing the tag and handing the remaining data back
4719 to mod_include for further processing.
4720 [Paul J. Reder <rederpj raleigh.ibm.com>]
4722 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
4723 fewer parameters: the local and remote socket addresses were removed
4724 from the parameter list because all required information is available
4725 via the APR socket. [Jeff Trawick]
4727 *) Distribution directory structure reorganized to reflect a
4728 normal source distribution with external install targets.
4731 *) The MPMs that need multiple segments of shared memory now create
4732 two apr_shmem_t variables, one for each shared memory allocation.
4733 the problem is that we can't determine how much memory will be required
4734 for shared memory allocations once we try to allocate more than one
4735 variable. The MM code automatically aligns the shared memory allocations,
4736 so we end up needing to pad the amount of shared memory we want based
4737 on how many variables will be allocated out of the shared memory segment.
4738 It is just easier to create a second apr_shmem_t variable, and two
4739 shmem memory blocks.
4742 *) Cleanup the export list a bit. This creates a single unified list of
4743 functions exported by APR. The export list is generated at configure
4744 time, and that list is then used to generate the exports.c file.
4745 Because of the way the export list is generated, we only export those
4746 functions that are valid on the platform we are building on.
4749 *) Enable logging the cookie with mod_log_config
4750 [Sander van Zoest <sander covalent.net>]
4752 *) Fix a segfault in mod_info when it reaches the end of the configuration.
4755 *) Added lib/aputil/ as a placeholder for utility functions which are not
4756 specific to the Apache HTTP Server (but do not make sense with APR).
4757 The first utility is "apu_dbm": a set of functions to work with DBM
4758 files. This first version can be compiled for SDBM or GDBM databases.
4761 *) Complete re-write of mod_include. This makes mod_include a filter that
4762 uses buckets directly. This has now served the FAQ correctly.
4763 [Paul Reder <rederpj raleigh.ibm.com>]
4765 *) Allow modules to specify the first filter in a sub_request when
4766 making the sub_request. This keeps modules from having to change the
4767 output_filter immediately after creating the sub-request, and therefore
4768 skip the sub_req_output_filter. [Ryan Bloom]
4770 *) Update ab to accept URLs with IPv6 literal address strings (in the
4771 format described in RFC 2732), and to build Host header fields in
4772 the same format. This allows IPv6 literal address strings to be
4773 used with ab. This support has been tested against Apache 1.3 with
4774 the KAME patch, but Apache 2.0 does not yet work with this format
4775 of the Host header field. [Jeff Trawick]
4777 *) Accomodate an out-of-space condition in the piped logs and the
4778 rotatelogs.c code, and no longer churn log processes for this
4779 condition. [Victor J. Orlikowski]
4781 *) Add support for partial writes with apr_sendfile() to core_output_filter.
4784 Changes with Apache 2.0a8
4786 *) Add a directive to mod_mime so that filters can be associated with
4790 *) Get multi-views working again. We were setting the path_info
4791 field incorrectly if we couldn't find the specified file.
4794 *) Fix 304 processing. The core should never try to send the headers
4795 down the filter stack. Always, just setup the table in the request
4796 record, and let the header filter convert it to data that is ready
4800 *) More fixes for the proxy. There are still bugs in the proxy code,
4801 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
4805 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
4808 *) APR: Add new apr_getopt_long function to handle long options.
4809 [B. W. Fitzpatrick <fitz red-bean.com>]
4811 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
4812 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
4813 hostname resolution/address string parsing and building
4814 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
4815 of one of the apr_sockaddr_t structures for a socket. Change
4816 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
4818 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
4819 I have proxied pages with it, cleanup will commence soon.
4822 *) Make the proxy work with filters. This isn't perfect, because we
4823 aren't dealing with the headers properly. [Ryan Bloom]
4825 *) Do not send a content-length iff the C-L is 0 and this is a head
4826 request. [Ryan Bloom]
4828 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
4829 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
4831 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
4833 *) Get the default_handler to stop trying to deal with HEAD requests.
4834 The idea is to let the content-length filter compute the C-L before
4835 we try to send the data. If we can get the C-L correctly, then we
4836 should send it in the HEAD response.
4839 *) The Header filter can now determine if a body should be sent based
4840 on r->header_only. The general idea of this is that if we delay
4841 deciding to send the body, then we might be able to compute the
4842 content-length correctly, which will help caching proxies to cache
4843 our data better. Any handler that doesn't want to try to compute
4844 the content-length can just send an EOS bucket without data and
4845 everything will just work.
4848 *) Add the referer to the error log if one is available.
4849 [Markus Gyger <mgyger itr.ch>]
4851 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
4852 change, the root of the configuration tree has been exposed to modules
4854 [Ryan Morgan <rmorgan covalent.net>]
4856 *) Get the core_output_filter to use the bucket interface directly.
4857 This keeps us from calling the content-length filter multiple times
4858 for a simple static request.
4861 *) We are sending the content-type correctly now.
4862 [Ryan Bloom and Will Rowe]
4864 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
4865 a bogus bytes-sent value when the only thing being sent was trailers
4866 and writev() returned an error (or EAGAIN). [Jeff Trawick]
4868 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
4869 hints file to determine which platforms define
4870 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
4873 *) APR: add apr_get_home_directory() [Jeff Trawick]
4875 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
4877 *) Not all platforms have INADDR_NONE defined by default. Apache
4878 used to make this check and define INADDR_NONE if appropriate,
4879 but APR needs the check too, and I suspect other applications will
4880 as well. APR now defines APR_INADDR_NONE, which is always a valid
4881 value on all platforms.
4882 [Branko Èibej <brane xbc.nu>]
4884 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
4885 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
4887 *) Relax the syntax checking of Host: headers in order to support
4888 iDNS. PR#6635 [Tony Finch]
4890 *) When reading from file buckets we convert to an MMAP if it makes
4891 sense. This also simplifies the default handler because the
4892 default handler no longer needs to try to create MMAPs.
4895 *) BUFF has been removed from the main server. The BUFF code will remain
4896 in the code until it has been purged from the proxy module as well.
4899 *) Byteranges have been completely re-written to be a filter. This
4900 has been tested, and I believe it is working correctly, but it could
4901 doesn't work for the Adobe Acrobat plug-in. The output almost matches
4902 the output from 1.3, the only difference being that 1.3 includes
4903 a content-length in the response, and this does not.
4906 *) APR read/write functions and bucket read functions now operate
4907 on unsigned integers, instead of signed ones. It doesn't make
4908 any sense to use signed ints, because we return the error codes,
4909 so if we have an error we should report 0 bytes read or written.
4912 *) Always compute the content length, whether it is sent or not.
4913 The reason for this, is that it allows us to correctly report
4914 the bytes_sent when logging the request. This also simplifies
4915 content-length filter a bit, and fixes the actual byte-reporing
4916 code in mod_log_config.c
4919 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
4920 it says, because it was only used by EOS and FLUSH buckets. Since
4921 neither of those are required at the end of a brigade, this was
4922 really signifying FLUSH_THE_DATA, but that can be determined better
4923 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
4924 buckets now return a length of 0, which is actually the amount of data
4925 read, so they make more sense.
4928 *) Allow the core_output_filter to save some data past the end of a
4929 request. If we get an EOS bucket, we only send the data if it
4930 makes sense to send it. This allows us to pipeline request
4931 responses. As a part of this, we also need to allocate mmap
4932 buckets out of the connection pool, not the request pool. This
4933 allows the mmap to outlive the request.
4936 *) Make blocking and non-blocking bucket reads work correctly for
4937 sockets and pipes. These are the only bucket types that should
4938 have non-blocking reads, because the other bucket types should
4939 ALWAYS be able to return something immediately.
4942 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
4943 server, but use Ctrl+Break to initiate a graceful restart
4944 instead of duplicating behavior. [John Sterling]
4946 *) Patch mod_autoindex to set the Last-Modified header based on
4947 the directory's mtime, and add the ETag header. [William Rowe]
4949 *) Merge the 1.3 patch to add support for logging query string in
4950 such a way that "%m %U%q %H" is the same as "%r".
4953 *) Port three log methods from mod_log_config 1.3 to 2.0:
4954 CLF compliant '-' byte count, method and protocol.
4957 *) Add a new LogFormat directive, %c, that will log connection
4958 status at the end of the response as follows:
4959 'X' - connection aborted before the response completed.
4960 '+' - connection may be kept-alive by the server.
4961 '-' - connection will be closed by the server.
4964 *) Expand APR for WinNT to fully accept and return utf-8 encoded
4965 Unicode file names and paths for Win32, and tag the Content-Type
4966 from mod_autoindex to reflect that charset if the the feature
4967 macro APR_HAS_UNICODE_FS is true. [William Rowe]
4969 *) Compute the content length (and add appropriate header field) for
4970 the response when no content length is available and we can't use
4971 chunked encoding. [Jeff Trawick]
4973 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
4974 so that content input filters get dechunked data when using
4975 the default handler. Also removed REQUEST_CHUNKED_PASS.
4978 *) Add mod_ext_filter as an experimental module. This module allows
4979 the administrator to use external programs as filters. Currently,
4980 only filtering of output is supported. [Jeff Trawick]
4982 *) Most Apache functions work on EBCDIC machines again, as protocol
4983 data is now translated (again). [Jeff Trawick]
4985 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
4986 the EBCDIC support. They are noops on ASCII machines, so this
4987 type of translation doesn't have to be surrounded by #ifdef
4988 CHARSET_EBCDIC. [Jeff Trawick]
4990 *) Fix mod_include. tag commands work again, and the server will
4991 send the FAQ again. This also allows mod_include to set aside
4992 buckets that include partial buckets.
4993 [Ryan Bloom and David Reid]
4995 *) Add suexec support back. [Manoj Kasichainula]
4997 *) Lingering close now uses the socket directly instead of using
4998 BUFF. This has been tested, but since all we can tell is that it
4999 doesn't fail, this needs to be really hacked on.
5002 *) Allow filters to modify headers and have those headers be sent to
5003 the client. The idea is that we have an http_header filter that
5004 actually sends the headers to the network. This removes the need
5005 for the BUFF to send headers.
5008 *) Charset translation: mod_charset_lite handles translation of
5009 request bodies. Get rid of the xlate version of ap_md5_digest()
5010 since we don't compute digests of filtered (e.g., translated)
5011 response bodies this way anymore. (Note that we don't do it at
5012 all at the present; somebody needs to write a filter to do so.)
5015 *) Input filters and ap_get_brigade() now have a input mode parameter
5016 (blocking, non-blocking, peek) instead of a length parameter.
5019 *) Update the mime.types file to the registered media types as
5020 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
5023 *) Namespace protect some macros declared in ap_config.h
5026 *) Support HTTP header line folding with input filtering.
5029 *) Mod_include works again. This should still be re-written, but at
5030 least now we can serve an SHTML page again.
5033 *) Begin to remove BUFF from the core. Currently, we keep a pointer
5034 to both the BUFF and the socket in the conn_rec. Functions that
5035 want to use the BUFF can, functions that want to use the socket,
5036 can. They point to the same place.
5039 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
5040 [Tomas "Ögren" <stric ing.umu.se>]
5042 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
5043 associated pool goes away. (APR pipes on OS/2 were already had this
5044 logic.) This resolvs a fatal file descriptor leak with CGIs.
5047 *) The final line of the config file was not being read if there was
5048 no \n at the end of it. This was caused by apr_fgets returning
5049 APR_EOF even though we had read valid data. This is solved by
5050 making cfg_getline check the buff that was returned from apr_fgets.
5051 If apr_fgets return APR_EOF, but there was data in the buf, then we
5052 return the buf, otherwise we return NULL.
5055 *) Piped logs work again in the 2.0 series.
5058 *) Restore functionality broken by the mod_rewrite security fix:
5059 rewrite map lookup keys and default values are now expanded
5060 so that the lookup can depend on the requested URI etc.
5061 PR #6671 [Tony Finch]
5063 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
5064 security bug in some mass virtual hosting configurations
5065 that can allow a remote attacker to retrieve some files
5066 on the system that should be inaccessible. [Tony Finch]
5068 *) Add a pool bucket type. This bucket is used for data allocated out
5069 of a pool. If the pool is cleaned before the bucket is destroyed, then
5070 the data is converted to a heap bucket, allowing it to survive the
5074 *) Add a flush bucket. This allows modules to signal that the filters
5075 should all flush whatever data they currently have. There is no way
5076 to actually force them to do this, so if a filter ignores this bucket,
5077 that's life, but at least we can try with this.
5080 *) Add an output filter for sub-requests. This filter just strips the
5081 EOS bucket so that we don't confuse the main request's core output
5082 filter by sending multiple EOS buckets. This change also makes sub
5083 requests start to send EOS buckets when they are finished.
5086 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
5087 makes ap_bucket_destroy a return void, which is okay because it
5088 used to always return APR_SUCCESS, and nobody ever checked its
5089 return value anyway.
5090 [Cliff Woolley <cliffwoolley yahoo.com>]
5092 *) Remove the index into the bucket-type table from the buckets
5093 structure. This has now been replaced with a pointer to the
5094 bucket_type. Also add some macros to test the bucket-type.
5097 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
5098 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
5099 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
5100 All _VAR_ flavors changes to _DATA to be absolutely clear.
5103 *) Add support for /, //, //servername and //server/sharename
5104 parsing of <Directory> blocks under Win32 and OS2.
5105 [Tim Costello, William Rowe, Brian Harvard]
5107 *) Remove the function pointers from the ap_bucket type. They have been
5108 replaced with a global table. Modules are allowed to register bucket
5109 types and use then use those buckets.
5112 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
5113 once we finish writing the request body to the cgi child process;
5114 otherwise, the client doesn't hit EOF on stdin. Small request bodies
5115 worked without this change (for reasons I don't understand), but large
5116 ones didn't. [Jeff Trawick]
5118 *) Remove file bucket specific information from the ap_bucket type.
5119 This has been moved to a file_bucket specific type that hangs off
5120 the data pointer in the ap_bucket type.
5123 *) Input filtering now has a third argument. This is the amount of data
5124 to read from lower filters. This argument can be -1, 0, or a positive
5125 number. -1 means give me all the data you have, I'll deal with it and
5126 let you know if I need more. 0 means give me one line and one line
5127 only. A positive number means I want no more than this much data.
5129 Currently, only 0 and a positive number are implemented. This allows
5130 us to remove the remaining field from the conn_rec structure, which
5134 *) Big cleanup of the input filtering. The goal is that http_filter
5135 understands two conditions, headers and body. It knows where it is
5136 based on c->remaining. If c->remaining is 0, then we are in headers,
5137 and http_filter returns a line at a time. If it is not 0, then we are
5138 in body, and http_filter returns raw data, but only up to c->remaining
5139 bytes. It can return less, but never more.
5140 [Greg Ames, Ryan Bloom, Jeff Trawick]
5142 *) mod_cgi: Write all of the request body to the child, not just what
5143 the kernel would accept on the first write. [Jeff Trawick]
5145 *) Back out the change that moved the brigade from the core_output_filters
5146 ctx to the conn_rec. Since all requests over a given connection
5147 go through the same core_output_filter, the ctx pointer has the
5151 *) Fix another bug in the send_the_file() read/write loop. A partial
5152 send by apr_send would cause unsent data in the read buffer to
5153 get clobbered. Complete making send_the_file handle partial
5154 writes to the network.
5157 *) Fix a couple of type fixes to allow compilation on AIX again
5158 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
5160 *) Fix bug in send_the_file() which causes offset to be ignored
5161 if there are no headers to send.
5164 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
5165 filter. Useful for supporting Windows 9* with a binary
5166 compiled on Windows NT.
5169 Changes with Apache 2.0a7
5171 *) Reimplement core_output_filter to buffer/save bucket brigades
5172 across multiple calls to the core_filter. The brigade will be
5173 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
5174 thresholds are hit or the EOS bucket is received.
5177 *) Create experimental filter (buffer_filter) that coalesces bytes
5178 into one large buffer before invoking the next filter in the
5179 chain. This filter is particularly useful with the current
5180 implementation of mod_autoindex when it inserted above the
5181 chunk_filter. mod_autoindex generates a lot of brigades that
5182 containing buckets holding just a few bytes each. The
5183 buffer_filter coalesces these buckets into a single large bucket.
5186 *) Add apr_sendfile() support into the core_output_filter.
5189 *) Add apr_sendv() support into the core_output_filter.
5192 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
5193 [Mike Abbott <mja sgi.com>]
5195 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
5196 make much sense, because Apache uses buckets instead of BUFFs now.
5199 *) send_the_file now falls back to a read/write loop on platforms that
5200 do not have sendfile.
5201 [Ryan Bloom and Brian Havard]
5203 *) Install apachectl correctly, and substitute the proper values so
5204 that it works again. [Ryan Bloom]
5206 *) Better(??) handle platforms that lack sendfile().
5209 *) APR now has UUID generation/formatting/parsing support.
5212 *) Begin the http_filter. This is an input filter that understands
5213 the absolute basic amount required to parse an HTTP Request. The
5214 goal is to be able to split headers from request body before passing
5215 the data back to the other filters.
5218 *) Bring forward from 1.3.13 the config directory implementation
5221 *) install apxs if it is created
5224 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
5225 conversions. [William Rowe]
5227 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
5228 ap_add_output_filter(). [Jeff Trawick]
5230 *) Multiple build and configuration fixes
5233 -add datadir and localstatedir substitutions
5235 -fix logfilename misspelling
5236 -fix evaluation of installation dir variables and
5237 -replace $foobar by $(foobar) to be usefull in the makefile
5241 -add rules for cross-compiling in rules.mk. Okay, rule to check for
5242 $CC_FOR_BUILD is still missing
5243 -use CHECK_TOOL instead of CHECK_PROG for ranlib
5244 -add missing "AR=@AR@" to severaly Makefile.in's
5245 -cache result for "struct rlimit"
5246 -compile all helper programs with native and cross compiler
5247 and use the native version to generate header file
5248 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5250 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
5252 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5254 *) Fix a bug where a client which only sends \n to delimit header
5255 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
5256 message. Start working on ebcdic co-existance with input
5258 [William Rowe, Greg Ames]
5260 *) If mod_so is enabled in the server always create libexec, even
5261 if there are no modules installed in this directory. This is a
5262 requirement for APXS to work correctly.
5265 *) Connection oriented output filters are now stored in the
5266 conn_rec instead of the request_rec. This allows us to add the
5267 output filter in the pre-connection phase instead of the
5268 post_read_request phase, which keeps us from trying to write an
5269 error page before we have a filter to write to the network.
5270 [Ryan Bloom, Jeff Trawick, and Greg Ames]
5272 *) Cleaning up an mmap bucket no longer deletes the mmap. An
5273 mmap can be used across multiple buckets (default_handler with
5274 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
5275 the mmap itself can't be associated with the bucket.
5278 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
5281 *) Radical surgery to improve mod_isapi support under Win32.
5282 Includes a number of newer ServerSupportFunction calls, support
5283 for ReadClient (in order to retrieve POSTs greater than 48KB),
5284 and general bug fixes to more reliably load ISAPI .dll's and
5285 prevent leaking handle resources. Note: There are still
5286 discrepancies between IIS's and Apache's ServerVariables, and
5287 async calls are still not supported. Additional warnings are
5288 logged to facilitate debugging of unsupported ISAPI calls.
5291 *) Add input filtering to Apache. The basic idea for the input
5292 filters is the same as the ideas for output filters. The biggest
5293 difference is that instead of calling ap_pass_brigade, ap_get_brigade
5294 should be called, and the order of execution for the filter itself is
5295 different. When writing an output filter, a brigade is passed in,
5296 and filters operate directly on that brigade, when done, they call
5297 ap_pass_brigade. Input filters are the exact opposite. Because input
5298 is not a push operation, filters first call ap_get_brigade. When this
5299 function returns, the input filter will be left with a valid brigade.
5300 The input filter should then operate on the brigade, and return.
5303 *) Fix building on BSD/OS using its native make. The build system
5304 falls back to the BSD .include directive on that host platform.
5307 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
5308 SHA1 and plaintext password encodings. Make feature tests a
5309 bit more flexible. [William Rowe]
5311 *) Charset translation: mod_charset_lite handles output content
5312 translation in a filter. mod_charset_lite no longer ignores
5313 subrequests. A bunch of cruft related to BUFF's support for
5314 translating request and response bodies was removed.
5317 *) Move the addition of the CORE filter to the post_read_request
5318 hook in http_core.c. This removes the need to add the filter in
5319 multiple places and allows for an SSL module to be added much
5320 simpler. [Ryan Bloom]
5322 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
5323 Fix a security problem that affects certain configurations of
5324 mod_rewrite. If the result of a RewriteRule is a filename that
5325 contains expansion specifiers, especially regexp backreferences
5326 $0..$9 and %0..%9, then it may be possible for an attacker to
5327 access any file on the web server. [Tony Finch]
5329 *) Fix a bug where errors that are detected during early request parsing
5330 don't produce visible HTTP error messages at the browser, because
5331 the core_filter wasn't present. [Greg Ames]
5333 *) Provide apr_socklen_t as a portability aid.
5334 [Victor J. Orlikowski]
5336 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
5337 as well as a comment arg to the add, adduser and update cmds.
5338 update allows the user to clear or preserve pw/groups/comment.
5339 Fixed a bug in dbmmanage that prevented the check option from
5340 parsing a password followed by :group... text. Corrected the
5341 seed calcualation for Win32 systems, and added -lsdbm support.
5344 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
5347 *) Avoid a segfault when parsing .htaccess files. An
5348 uninitialized tree pointer was passed to ap_build_config().
5351 *) Change the way that inet_addr & inet_network are checked for
5352 in APR's configure process to allow BeOS BONE to correctly
5353 find them. With this change BeOS BONE now builds from source
5354 with no problems. [David Reid]
5356 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
5357 the end of the parameters to execve() was stored in the wrong
5358 location, overlaying the storage beyond the newargs[] array and
5359 also passing uninitialized storage to execve(), which would
5360 sometimes fail with EFAULT. [Jeff Trawick]
5362 *) Fix a bug parsing configuration file containers. With a sequence
5363 like this in the config file
5365 <IfModule mod_kilroy.c>
5368 <IfModule mod_lovejoy.c>
5373 the second container would be terminated at the blank line due to
5374 sediment in the buffer from reading the prior </IfModule> and an
5375 error message would be generated for the real </IfModule> for the
5376 second container. Also due to this problem, any two characters
5377 could be used for "</" in the close of a container.
5380 *) ap_add_filter prototype changed to remove the ctx pointer. The
5381 pointer still remains in the filter structure, but it can not be
5382 a part of the ap_add_filter prototype. The reason is that when
5383 the core uses AddFilter to add a filter to the stack it doesn't
5384 know how to allocate the ctx pointer, or even how much memory should
5385 be allocated. The filters will have to be responsible for allocating
5386 the ctx memory when they need it.
5389 *) Add an AddFilter directive. This directive takes a list of filters
5390 that should be activated for the requested resource.
5393 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
5394 some other platforms). [Jeff Trawick]
5396 *) Modify mod_include to be a filter. Currently, it has only been tested
5397 on actual files, but it should work for CGI scripts too.
5400 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
5401 writes. apr_flush() for Unix: handle interrupted writes.
5404 *) NameVirtualHost can now take "*" as an argument instead of
5405 an IP address. This allows you to create a purely name-based
5406 virtual hosting server that does not have any IP addresses in
5407 the configuration file and which ignores the local address
5408 of any connections. PR #5595, PR #4455 [Tony Finch]
5410 *) Fix some compile warnings in mod_mmap_static.c
5411 [Mike Abbott <mja sgi.com>]
5413 *) Fix chunking problem with CGI scripts. The general problem was that
5414 the CGI modules were adding an EOS bucket and then the core added an
5415 EOS bucket. The chunking filter finalizes the chunked response when it
5416 encounters an EOS bucket. Because two EOS buckets were sent, we
5417 finalized the response twice. The fix is to make sure we only send one
5418 EOS, by utilizing a flag in the request_rec.
5421 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
5422 and Win32. Previously, the first read from an apr_file_t set up via
5423 apr_put_os_file() would return a '\0'. [Jeff Trawick]
5425 *) Mod_cgid now creates a single element bucket brigade, with a pipe
5426 bucket, instead of using BUFF's and ap_r*.
5429 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
5430 [Mike Abbott <mja sgi.com>]
5432 *) Remove ap_bopenf from buff code. This required modifying the file_cache
5433 code to use APR file's directly instead of going through BUFFs.
5436 *) Fix compile break on some platforms for mod_mime_magic.c
5437 [John K. Sterling <sterling covalent.net>]
5439 *) Fix merging of AddDefaultCharset directive.
5440 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
5442 *) Minor revamp of the rlimit sections of code. We now test
5443 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
5444 is now "available" even if the platform doesn't support
5445 the rlimit family (it's just a noop though). [Jim Jagielski]
5447 *) Migrate the pre-selection of which MPM to use for specific
5448 platforms to hints.m4, which contains (or should contain)
5449 all platform specific "hints". [Jim Jagielski]
5451 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
5454 *) Add tables with non-string/binary values to APR.
5457 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
5460 *) Update PCRE to version 3.2. [Ryan Bloom]
5462 *) Change the way buckets' destroy functions are called so that
5463 they can be more directly used when changing the type of a
5464 bucket in place. [Tony Finch]
5466 *) Add generic support for reference-counting the resources used by
5467 buckets, and alter the HEAP and MMAP buckets to use it. Change
5468 the way buckets are initialised to support changing the type of
5469 buckets in place, and use it when setting aside TRANSIENT buckets.
5470 Change the implementation of TRANSIENT buckets so that it can be
5471 mostly shared with IMMORTAL buckets, which are now implemented.
5474 Changes with Apache 2.0a6
5476 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
5478 *) Add a chunking filter to Apache. This brings us one step closer
5479 to removing BUFF. [Ryan Bloom]
5481 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
5482 added to the stack is the last filter to be called. [Ryan Bloom]
5484 *) Apache 2.0 has been completely documented using Scandoc. The
5485 docs can be generated by running 'make docs'. [Ryan Bloom]
5487 *) Add filtered I/O to Apache. This is based on bucket brigades,
5488 Currently the buckets still use BUFF under the covers, but that
5489 should change quickly. The only currently written filter is the
5490 core filter which just calls ap_bwrite. [The Apache Group]
5492 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
5493 built with thread support. [Jeff Trawick]
5495 *) Abort configuration if --with-layout was specified and there's
5496 no layout definition file. [Ken Coar]
5498 *) Add support for '--with-port=n' option to configure. [Ken Coar]
5500 *) Add support for extension methods for the Allow response header
5501 field, and an API routine for accessing r->allowed and the
5502 list of extension methods in a unified manner. [Ken Coar]
5504 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5505 [Rob Simonson <simo us.ibm.com>]
5507 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5508 APACHE_XLATE builds. [Jeff Trawick]
5510 *) A configuration file parsing problem was fixed. When the
5511 configuration file started with an IfModule/IfDefine container,
5512 only the last statement in the container would be retained.
5515 Changes with Apache 2.0a5
5517 *) Perchild is serving pages after passing them to different child
5518 processes. There are still a lot of bugs, but this does work. I
5519 have made requests against the same installation of Apache, and had
5520 different servers use different user IDs to serve the responses.
5521 This change moves to using socketpair instead of an AF_UNIX socket.
5524 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5525 It can't seem to pass between child processes yet, but I think we
5526 are closer now than before. This moves us back to using Unix
5527 Domain Sockets. [Ryan Bloom]
5529 *) libapr functions and types renamed with apr_ prefix.
5530 #include "apr_compat.h" for 1.3.x backwards compat
5533 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5534 return the right information on the local socket address.
5535 [Gregory Nicholls <gnicholls level8.com>]
5537 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5538 [Gregory Nicholls <gnicholls level8.com>]
5540 *) Add an option to not detach from the controlling terminal without
5541 going into single process mode. This allows for much easier
5542 debugging of the process startup code. [Ryan Bloom]
5544 *) ab: don't use perror() to report the failure of an APR function.
5547 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5548 scoreboard on graceful restarts.
5551 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5552 An invalid ap_proc_t was passed to ap_create_process().
5555 *) Allow modules to register filters. Those filters are still
5556 never called, but this is a step in the right direction.
5557 [Ryan Bloom and Greg Stein]
5559 *) Register the mod_cgid daemon process for cleanup so that it is
5560 killed at termination if it does not die when the parent gets
5561 SIGTERM. This change is to fix occasional problems where the
5562 process stays around. Bugs in similar logic in mod_rewrite and
5563 mod_include were also fixed. [Jeff Trawick]
5565 *) Fix a bug in the time handling. Basically, we were imploding a time
5566 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5567 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5568 uses those two fields to adjust the time value. Because of the HTTP
5569 spec, both of those values can be zero'ed out safely. This fixes
5570 the bug correctly. [Ryan Bloom]
5572 *) Fix a couple of place in the Windows code where the wrong error
5573 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
5575 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5577 *) Added the APR_EOL_STR macro for platform dependent differences in
5578 logfiles and other raw text (such as all APR files). Fixes logfiles
5579 not terminated with cr/lf sequences in Win32. [William Rowe]
5581 *) Move all strings functions in APR to src/lib/apr/strings and create
5582 apr_strings.h for the prototypes. [Ryan Bloom]
5584 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5585 to repeat the syscall until we stop getting EINTR. I noticed a
5586 related problem at termination (SIGTERM) on FreeBSD when using
5587 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5588 implementation work properly with child init. Previously, ap_lock()
5589 was essentially a no-op because all children were using different
5590 locks and thus nobody ever blocked. [Jeff Trawick]
5592 *) The htdocs/ tree has been moved out of the CVS source tree into
5593 a separate area for easier development. This has NO EFFECT on
5594 end-users or Apache installations. [Ken Coar]
5596 *) Integrate the mod_dav module for WebDAV protocol handling. This
5597 adds the dav and dav_fs modules, the SDBM library, and additional
5598 XML handling utilities. [Greg Stein]
5600 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
5603 *) Update the lib/expat-lite/ library (bring forward changes from
5604 the Apache 1.3 repository). [Greg Stein]
5606 *) If sizeof(long long) == sizeof(long), then prefer long in APR
5607 configure.in. [Dave Hill <ddhill zk3.dec.com>]
5609 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
5610 machines where sendfile is detected, but nobody has written ap_sendfile.
5611 [Dave Hill <ddhill zk3.dec.com>]
5613 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
5615 *) ab would start up more connections than needed, then quit when the
5616 desired number were finished. Also fixed a logic error involving
5617 ab keepalives. [Victor J. Orlikowski]
5619 *) WinNT: Implement non-blocking pipes with timeouts to communicate
5620 with CGIs. Apache 2.0a4 had non-blocking pipes but without
5621 timeouts (i.e, if a timeout was specified, the pipe reverted to
5622 a full blocking pipe). Now the behaviour is more in line with
5623 Unix non-blocking pipes.
5626 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
5627 cache open file handles along with accept socket reuse enables
5628 Apache 2.0 to serve non-keepalive requests for static files at
5629 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
5630 and Apache 2.0 will serve almost 1200 rps on my system).
5633 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
5634 supports two config directives, mmapfile (same behavious as
5635 mod_mmap_static) and cachefile. Use the cachefile directive
5636 to cache open file handles. This directive only works on systems
5637 that have implemented the ap_sendfile API. cachefile works today
5638 on Windows NT, but has not been tested on any flavors of Unix.
5641 *) Cleanup the configuration. With the last few changes the
5642 configuration process automatically:
5643 inherits information about how to build from APR. Allowing
5644 APR to inform Apache that it should or should not use -ldl
5646 Detects which mod_cgi should be used mod_cgi or mod_cgid,
5647 based on the threading model
5649 Apache calls APR's configure process before finishing it's
5650 configuration processing, allowing for more information flow
5655 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
5656 with non-zero argument makes the socket non-blocking. BeOS and
5657 OS/2 already worked this way. [Jeff Trawick]
5659 *) ap_close() now calls ap_flush() for buffered files, so write
5660 operations work a whole lot better on buffered files.
5663 *) Fix error messages issued from MPMs which explain where to change
5664 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
5667 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
5668 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
5669 now the way that the blocking state of a pipe is manipulated.
5670 ap_block_pipe() is gone. [Jeff Trawick]
5672 *) Correct the problem where the only local host name that the IP stack
5673 can discover are 'undotted' private names. If no fully qualified
5674 domain name can be identified, the default ServerName will be set to
5675 the machine's IP address string. A warning is always provided if the
5676 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
5678 *) Repair problems with config file processing which caused segfault
5679 at init when virtual hosts were defined and which caused ServerName to
5680 be ignored when there was no valid DNS setup. [Jeff Trawick]
5682 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
5684 *) Add ap_sendfile implementation for AIX
5685 [Victor J. Orlikowski]
5687 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
5688 apr_network_io.h, and apr_thread_proc.h.
5689 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
5691 *) Bring the allocation and pool debugging code back into a working
5692 state. This will need to be tested as so far it's only been used on
5695 *) Change configuration command setup to be properly typesafe when in
5696 maintainer mode. Note that this requires a compiler that can initialise
5697 unions. [Ben Laurie]
5699 *) Turn on buffering for config file reads. Part of this was to
5700 repair buffered I/O support in Unix and implement buffered
5701 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
5703 *) Win32: Fix problem where UTC offset was not being set correctly
5704 in the access log. Problem reported on news group by Jerry Baker.
5707 *) Fix segfault when reporting this type of syntax error:
5708 "</container> without matching <container> section", where
5709 container is VirtualHost or Directory or whatever.
5712 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
5713 Prevent the source code for CGIs from being revealed when
5714 using mod_vhost_alias and the CGI directory is under the document root
5715 and a user makes a request like http://www.example.com//cgi-bin/cgi
5716 as reported in <news:960999105.344321 ernani.logica.co.uk>
5719 *) Add support for the new Beos NetwOrking Environment (BONE)
5722 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
5723 final input char is incomplete; ap_bwrite_xlate() now handles
5724 incomplete final input chars. [Jeff Trawick]
5726 *) Yet another update to saferead/halfduplex stuff -- need to ensure
5727 that a bhalfduplex call occurs before logging or else DNS and
5728 such can delay the last packet of the response. [Dean Gaudet]
5730 *) Some syscall reduction in APR on unix -- don't seek when setting
5731 up an mmap; and don't fcntl() more than once per socket.
5734 *) When mod_cgid is started as root, the cgi daemon now switches
5735 to the configured User/Group (like other httpd processes)
5736 instead of continuing as root. [Jeff Trawick]
5738 *) The prefork MPM now uses an APR lock for the accept() mutex.
5739 It has not been getting a lock at all recently. httpd -V now
5740 displays APR's selection of the lock mechanism instead of the
5741 symbols previously respected by prefork. [Jeff Trawick]
5743 *) Change the mmap() feature test to check only for existence.
5744 The previous check required features not used by Apache.
5747 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
5748 sometimes mangled. The len parm to accept() was not
5749 initialized, leading sometimes to an endless loop of failed
5750 accept() calls on OS/390 and anywhere else that failed the call
5751 if the len was negative. Use <sys/un.h> for struct sockaddr_un
5752 instead of declaring it ourselves to fix a compilation problem
5753 on Solaris. [Jeff Trawick]
5755 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
5757 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
5759 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
5761 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
5762 initialization if ALLOC_DEBUG is defined; no known symptom
5763 otherwise. [Jeff Trawick]
5765 *) Fix typo in configure script when checking for mod_so. bash
5766 doesn't seem to have a problem but /bin/sh on Solaris does.
5767 Symptom: "./configure: test: unknown operator =="
5770 *) Rebind the Win32 NT and 9x services control into the MPM.
5771 All console, WinNT SCM and Win9x pseudo-service control code is
5772 now wrapped within the WinNT MPM.
5775 *) Make a copy of getenv("PATH") before storing for later use. Some
5776 getenv() implementations use the same storage for successive calls.
5777 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
5779 *) Server Tokens work in 2.0 again. This also propogates the change
5780 to allow just the product name in the server string using
5784 Changes with Apache 2.0a4
5786 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
5787 won't need to call it. [Greg Ames, Jeff Trawick]
5789 *) Move pre_config hook call to between configuration read and config
5790 tree walk. This allows all modules to implement pre_config hooks
5791 and know that they will be called at an appropriate time.
5794 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
5797 *) Add pre-config hooks back to all modules.
5800 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
5801 ContentDigest enabled and we can't/don't mmap the file.
5804 *) We now report the correct line number for syntax errors in config
5805 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
5807 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
5808 related bugs, and changed shmem/locking to use apr API. Shared-mem
5809 is currently disabled, however, because of problems with graceful
5810 restarts. [Ronald Tschalär]
5812 *) Fix corruption of IFS variable in --with-module= handling.
5813 Depending on the user's shell or customization thereof, there
5814 would be errors generating ap_config_auto.h later in the configure
5815 procedure. [Jeff Trawick]
5817 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
5818 isn't used (as in 1.3), except that on Unix it is now logged via
5819 ap_log_rerror() instead of by the child having STDERR_FILENO refer
5820 to the error log. [Greg Ames, Jeff Trawick]
5822 *) Add '-D' argument processing for run time configuration defines.
5825 *) Organize http_main.c as independent code, such that no code or
5826 global data is exported from it. WIN32 will dynamically link it
5827 to the server core, so this will prevent mutual dependency.
5830 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
5831 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
5834 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
5835 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
5837 *) Add mod_charset_lite for configuring character set translation.
5840 *) Add '-n' option to htpasswd to make it print its user:pw record
5841 on stdout rather than having to frob a text file. [Ken Coar]
5843 *) Fix saferead. Basically, we flush the output buffer if a read on the
5847 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
5848 a conversion is single-byte only. [Jeff Trawick]
5850 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
5851 the BeOS 5.0 documentation says that shutdown doesn't work yet.
5854 *) Fix some minor errors where pid was being manipulated as an int
5855 instead of the portable pid_t. [Roy Fielding]
5857 *) Fix some error log prints that were printing the pointer to a
5858 structure rather than the pid within the structure.
5859 [Jeff Trawick, Roy Fielding]
5861 *) ab: Fix a command-line processing bug; track bad headers in
5862 err_response; support reading headers up to 2K.
5863 [Ask Bjoern Hansen <ask valueclick.com>]
5865 *) Fix ap_resolve_env() so that it handles new function added in a prior
5866 alpha (see "Added the capability to do ${ENVVAR} constructs in the
5867 config file.") as well as the constructs used by mod_rewrite.
5868 [Paul Reder <rederpj raleigh.ibm.com>]
5870 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
5872 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
5873 APR to perform translation, instead of accessing the hard-coded tables
5874 in 1.3's ebcdic.c. [Jeff Trawick]
5876 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
5879 *) Add the ability to hook into the config file reading phase. Basically
5880 if a directive is specified EXEC_ON_READ, then when that directive is
5881 read from the config file, the assocaited function is executed. This
5882 should only be used for those directives that must muck with HOW the
5883 server INTERPRETS the config. This should not be used for directives
5884 that re-order or replace items in the config tree. Those changes should
5885 be made in the pre-config step.
5888 *) Add mod_example to the build system.
5891 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
5892 byte character sets. [Jeff Trawick]
5894 *) Pick up various EBCDIC fixes from 1.3 (from Martin
5895 Kraemer and Oliver Reh originally according to the change log).
5898 *) Fix a couple of problems in RFC1413 support (controlled by the
5899 IdentityCheck directive). Apache did not build the request string
5900 properly and more importantly Apache would loop forever if the
5901 would-be ident server dropped the connection before sending a
5902 properly terminated response. [Jeff Trawick]
5904 *) apxs works in 2.0.
5907 *) Reliable piped logs work in 2.0.
5910 *) Introduce a hash table implementation into APR to be used for
5911 replacing tables and other random data structures in Apache.
5914 *) Add some more error reporting to htpasswd in the case of problems
5915 generating or accessing the temporary file. Also, pass in a
5916 buffer if the implementation knows how to use it (i.e., if L_tmpnam
5917 is defined). [Ken Coar]
5919 *) Configure creates config.nice now containing your configure
5920 options. Syntax: ./config.nice [--more-options]
5923 *) Fix various return code problems in APR on Win32. For most of
5924 these, APR was returning APR_EEXIST instead of GetLastError()/
5925 WSAGetLastError(). [Jeff Trawick]
5927 *) Make piped logs work again in version 2.0
5930 *) Add VPATH support to UNIX build system of Apache and APR.
5933 *) Fix ap_tokenize_to_argv to respect the const arguments that are
5937 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
5938 Patch submitted to author.
5941 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
5942 /sbin in PATH on FreeBSD (all submitted to rse previously)
5945 *) Fix building Pthread-based MPMs on OpenBSD
5946 [Sascha Schumann] PR#26
5948 *) Fix ap_readdir() problem on systems where d_name[] field in
5949 struct dirent is declared with only one byte. (This problem only
5950 affected multithreaded builds.) This caused a segfault during
5951 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
5952 least). [Jeff Trawick]
5954 *) Fix some make-portability problems on at least Tru64, Irix
5956 [Sascha Schumann] PR#18, PR#39
5958 *) Add ap_sigwait() to support old-style sigwait() on systems
5959 like OS/390 and UnixWare.
5962 *) Add POSIX-thread flags for more platforms.
5965 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
5966 (on Unix, at least) to handle resolver errors. Fix a bug in
5967 the definition of APR_ENOMEM so that ap_strerror() can spit
5968 out the correct error message for it.
5971 Changes with Apache 2.0a3
5973 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
5976 *) API: *HOOK* macros now have an AP_ prefix
5979 *) Win32: Eliminate redundant calls to initialize winsock.
5980 [Tim Costello <timcostello ozemail.com.au>]
5982 *) Fix bugs initializing ungetchar for pipes.
5983 [Chia-liang Kao <clkao CirX.ORG>]
5985 *) The ab program in the src/support directory is now portable using
5989 *) Support directory is being compiled when the server is built
5992 *) The configure option --with-program-name has been added to allow
5993 developers to rename the executable at configure time. This also
5994 changes the name of the config files to match the executable's name.
5997 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
5998 containing version numbers. [Martin Pool]
6000 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
6001 Unix; access_log and error_log now created with these perms; non-
6002 Unix is unaffected [Jeff Trawick]
6004 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
6005 Replaced more magic numbers with MD5_DIGESTSIZE.
6006 [William Rowe, Roy Fielding]
6008 *) Win32: Get mod_auth_digest compiling and added to the Windows
6009 build environment. Not tested and I'd be suprised if it
6010 actually works. [Bill Stoddard]
6012 *) Revamp the Win32 make environment. Makefiles have been removed and
6013 Apache.dsw created to bring together all the pieces. Create new file
6014 os/win32/BaseAddr.ref to define module base addresses (to prevent
6015 dll relocation at start-up).
6016 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
6018 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
6019 of the \015, \012, and \015\012 constants with macros.
6022 *) Add ap_xlate_open() et al for translation of text between different
6023 character sets. The initial implementation requires iconv().
6026 *) More FAQs and answers from comp.infosystems.www.servers.unix.
6027 [Joshua Slive <slive finance.commerce.ubc.ca>]
6029 *) CGI output is being timed out now.
6032 *) Fix the problem with dieing quietly. dupfile now takes a pool which
6033 is used by the new apr file. There is no reason to create a new file
6034 with the same lifetime as the original file.
6037 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
6038 module base addresses. This will help shooting seg faults
6039 in the field. [William Rowe <wrowe lnd.com>]
6041 *) Update Apache on Windows documentation. Add new document
6042 describing how to compile Apache on Windows.
6043 [William Rowe <wrowe lnd.com>]
6045 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
6046 microseconds instead of seconds. Some storage leaks and other
6047 minor bugs in related code were fixed. [Jeff Trawick]
6049 *) Win32: First cut at getting mod_isapi working under 2.0
6050 [William Rowe <wrowe lnd.com>]
6052 *) First stab at getting mod_auth_digest working under 2.0
6053 quick change summary:
6054 - moved the random byte generation (ap_generate_random_bytes) into APR
6055 - now uses ap_time_t
6056 - compiles and runs on linux
6058 [Brian Martin <bmartin penguincomputing.com>]
6060 *) Win32: Move the space stripping of physical service names
6061 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
6062 unresolved symbol. Add dependency checking to the
6063 CreateService call to ensure TCPIP and AFP (winsock) is started
6065 [William Rowe <wrowe lnd.com>]
6067 *) Win32: Add code to perform latebinding on functions that may
6068 not exist on all levels of Windows where Apache runs. This
6069 is needed to allow Apache to start-up on Win95/98. All calls
6070 to non portable functions should be protected with
6071 ap_oslevel checks to prevent runtime segfaults.
6072 [William Rowe <wrowe lnd.com>]
6074 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
6076 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
6078 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
6079 This addresses PR 1623. Still need to address timing out runaway
6080 CGI scripts. [Bill Stoddard]
6082 *) Win32: Make ap_stat Windows 95/98 friendly
6083 [William Rowe <wrowe lnd.com>]
6085 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
6086 always fail. Need to initialise the dwOSVersionInfoSize member of the
6087 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
6090 The patch also enhances ap_get_oslevel (and the associated enum) to
6091 handle selected service packs for NT4, and adds recognition for
6092 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
6093 we can use ReadFileScatter and WriteFileGather in readwrite.c.
6094 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
6096 *) Get mod_rewrite building and running, and mod_status building for Win NT
6097 [Allan Edwards <ake raleigh.ibm.com>]
6099 *) Patch to port mod_auth_db to the 2.0 api and also to support
6100 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
6101 2.7.7. It should work with version 1 as well but I haven't tested it.
6102 [Brian Martin <bmartin penguincomputing.com>]
6104 *) Get APR DSO code working under Windows. Includes cross platform
6106 [<Tim.Costello BTFinancialgroup.com>]
6108 *) Fix some of the Windows APR time functions.
6111 *) FAQ changes related to tidying up historical documents on the web site.
6112 [Joshua Slive <slive finance.commerce.ubc.ca>]
6114 *) Move Windows DSO code into APR.
6117 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
6118 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
6119 at build time. At this point, the server will not compile on Windows because
6120 of the recent DSO commits. Fixing those next.
6121 [Bill Rowe & Bill Stoddard]
6123 *) Added error checking for file I/O APR routines.
6124 [Jon Travis <jtravis covalent.net>]
6126 *) APR: Don't use the values of resolver error codes for the
6127 corresponding APR error codes. On Unix and Win32, return the
6128 proper APR error code after a resolver error. [Jeff Trawick]
6130 Changes with Apache 2.0a2
6132 *) Renamed the executable back to httpd on all platforms other
6136 *) Allow BeOS to survive restarts, log properly and a few
6137 small things it had problems with due to the way it setup
6138 users and groups. [David Reid]
6140 *) Get mod_rewrite working with APR locks
6141 [Paul Reder <rederpj raleigh.ibm.com>]
6143 *) Actually remove the sempahore when the lock cleanup routine
6144 is called on BeOS. [David Reid]
6146 *) Clear hook registrations between reads of the config file.
6147 When DSOs are unloaded and re-loaded the old hook pointers may
6148 no longer be valid. This fix eliminates potential segfaults.
6149 [Allan Edwards <ake raleigh.ibm.com>]
6151 *) Fix a problem with Sigfunc not being defined or bypassed
6152 if sigaction() wasn't found. [Jim Jagielski]
6154 *) Fix the locking mechanism on BSD variants. They now use fcntl
6155 locks. This allows the server to start and serve pages.
6158 *) First cut at getting the Win32 installer to work
6159 [William Rowe <wrowe lnd.com>]
6161 *) Get htpasswd compiling under Windows
6162 [William Rowe <wrowe lnd.com>]
6164 *) Change the log message for a bind() failure to show the
6165 interface and port number. [Jeff Trawick]
6167 *) Import the documentation from 1.3.12 and bring parts of it
6168 up-to-date with respect to the changes that have occurred
6172 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
6173 now logged correctly on BeOS.
6176 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
6177 Makefile.win includes the same user interface as the old
6179 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
6181 *) Win32 exec now uses COMSPEC environment string for command
6182 shell path resolution.
6183 [William Rowe <wrowe lnd.com>] PR#3715
6185 *) Win32: ap_connect() was not returning correct error condition
6187 [Allen Prescott <allen clanprescott.com>]
6189 *) Win32: ap_open() was broken on Win9x because an NT-specific
6190 flag was passed to CreateFile. ap_puts() added an unnecessary
6192 [Jeff Trawick <trawick us.ibm.com>]
6194 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
6195 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
6196 confusing ee/et name and made all extensions language/dialect
6197 rather than country reflecting. Changed example files to
6198 explicit reflect the ISO charset and added a few common
6199 ones to the example config [dirkx]
6201 *) Extend external module capability. To use this, you call
6202 configure with --with-module=path/to/mod1,path/to/mod2,etc.
6205 *) Backported the various "default charset" fixes from 1.3.12,
6206 including the AddDefaultCharset directive. [Jim Jagielski]
6208 *) Added the capability to do ${ENVVAR} constructs in the
6209 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
6210 it does this on a line by line basis; i.e. if the envvar
6211 expands to something with spaces you have to protect it
6212 by adding quotes around it (Unless of course you expect it
6213 to contains more than one argument. Alternatively you
6214 can compile it on a per token basis; which is what people
6215 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
6216 hampers fancier hacks.
6217 [Dirk-Willem van Gulik]
6219 *) Changed the 'ErrorDocument' syntax in that it NO longer
6220 supports the asymetric
6222 ErrorDocument 301 "Some message
6224 Note the opening " quote, without a closing quote. It now
6225 has either the following syntaxes
6227 ErrorDocument XXX /local/uri
6228 ErrorDocument XXX http://valid/url
6229 ErrorDocument XXX "Some Message"
6231 The recognition heuristic is: if it has a space it
6232 is a message. If it has no spaces and starts with a /
6233 or is a valid URL then treat it that way. Otherwise it
6234 is assumed to be a message.
6236 This breaks backward compatibility but makes live a hell
6237 of a lot easier for GUI's and config file parsers.
6238 [Dirk-Willem van Gulik]
6240 *) Changed 'CacheNegotiatedDocs' from its present/not-present
6241 syntax into a 'on' or 'off' syntax. As it currently is the
6242 only non nesting token which uses NO_ARGS and thus is an
6243 absolute pain for any config interface automation. This
6244 breaks backward compatibility. [Dirk-Willem van Gulik]
6246 *) Add ability to add external modules to the build process. This is
6247 done with --with-module=/path/to/module. Modules can only be added
6248 as static modules at this point.
6251 Changes with Apache 2.0a1
6253 *) Fix FreeBSD 3.3 core dump.
6254 Basically, ap_initialize() needs to get called before
6255 create_process(), since create_process() passes op_on structure
6256 to semop() to get a lock, but op_on isn't initialized until
6257 ap_initialize() calls setup_lock(). Here is a slight
6258 rearrangement to main() which calls ap_initialize() earlier...
6259 [Jeff Trawick <trawick us.ibm.com>]
6261 *) Enable Apache to use sendfile/TransmitFile API
6262 [Bill Stoddard, David Reid, Paul Reder]
6264 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
6268 *) Make file I/O and network I/O writev/sendv APIs consistent.
6269 Eliminate use of ap_iovec_t and use Posix struct iovec.
6270 Use seperate variable on ap_writev to set the number of iovecs
6271 passed in and number of bytes written.
6274 *) Adapt file iol to use APR functions. Replaced ap_open_file()
6275 with ap_create_file_iol(). ap_create_file_iol() requires that
6276 the file be opened prior to the call using ap_open().
6279 *) Port mod_include and mod_cgi to 2.0
6280 [Paul Reder, Bill Stoddard]
6282 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
6283 bytes_read/bytes_written is always valid (never -1). Plus
6284 some fixes to buff.c to correct problems introduced by the
6285 errno => ap_status_t changes a while back. Plus a fix to
6286 chunked encoding introduced right at the beginning of 2.0.
6289 *) Revamped UNIX build system to use autoconf and libtool.
6290 [Manoj Kasichainula, Sascha Schumann]
6292 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
6294 *) SECURITY: More rigorous checking of Host: headers to fix security
6295 problems with mass name-based virtual hosting (whether using mod_rewrite
6296 or mod_vhost_alias).
6297 [Ben Hyde, Tony Finch]
6299 *) Add back support for UseCanonicalName in <Directory> containers.
6300 [Manoj Kasichainula]
6302 *) Added APLOG_STARTUP log type. This allows us to write an error
6303 message without any of the date and time information. As a part
6304 of this change, I also removed all of the calls to fprintf(stderr
6305 and replaced them with calls to ap_log_error using APLOG_STARTUP
6306 writing to stderr is no longer portable, because we don't direct
6307 stderr to the error log on all platforms.
6310 *) Convert error logging functions to take errno as an argument.
6311 This makes our error logs more portable, because some Windows API's
6312 don't set errno. This change allows us to still output a valid
6313 message on all of our platforms.
6316 *) mod_mime_magic runs in 2.0-dev now.
6317 [Paul Reder <rederpj raleigh.ibm.com>]
6319 *) sendfile has been added to APR.
6320 [John Zedlewski <zedlwski Princeton.EDU>]
6322 *) buff.c has been converted to no longer use errno.
6323 [Manoj Kasichainula]
6325 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
6326 interface adaption to APR functions did it. [Martin Kraemer]
6328 *) Support DSOs properly on 32-bit HP-UX 11.0
6329 [Dilip Khandekar <dilip cup.hp.com>]
6331 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
6332 [Ralf S. Engelschall]
6334 *) Cleaned APR build environment integration and bootstrap APR
6335 automatically for developers from src/Configure.
6336 [Ralf S. Engelschall]
6338 *) Fixed building of src/support/htpasswd.c
6339 [Ralf S. Engelschall]
6341 *) When generating the Location: header, mod_speling forgot
6342 to escape the spelling-fixed uri. (Forw-Port from 1.3)
6345 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
6347 *) Change all pools to APR contexts. This is the first step to
6348 incorporating APR into Apache. [Ryan Bloom]
6350 *) Move "handler not found" warning message to below the check
6351 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
6352 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
6354 *) Support line-continuation feature in config.option file and
6355 allow the loading of multiple option sections at once via
6356 ``--with-option=<section1>,<section2>,...''
6357 [Ralf S. Engelschall]
6359 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
6361 Changes with Apache MPM
6363 *) Use asynchronous AcceptEx() and a completion port to accept and
6364 dispatch connections to threads in Windows NT/2000.
6367 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
6370 *) Implement the APACI --with-option facility
6371 (per default used the config.option file).
6372 [Ralf S. Engelschall]
6374 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
6376 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
6377 Replace pre_connection module call with a register_hook call and
6378 implement pre_connection as a hook. The intent is that these hooks will
6379 be extended to allow Apache to be multi-protocol, and also to allow the
6380 calling order to be specified on a per-hook/per-module basis.
6383 *) Implement mpm_* methods as "modules". Each method gets its own
6384 subdir in src/modules (eg: src/modules/prefork). Selection
6385 of method uses Rule MPM_METHOD. [Jim Jagielski]
6387 *) Port the hybrid server from the apache-apr repository as
6388 mpm_mpmt_pthread. [Manoj Kasichainula]
6390 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
6391 amongst the unix MPMs.
6393 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
6394 signal handling for the new world order. [Dean Gaudet]
6396 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
6397 of alloc.c for now. [Dean Gaudet]
6399 *) Handle partial large writes correctly. [Ben Laurie]
6401 *) Eliminate conn_rec's pointer to server. All it knows is the base server
6402 based on IP/port. [Ben Laurie]
6404 *) Port a bunch of modules to the new module structure.
6405 ["Michael H. Voase" <mvoase midcoast.com.au>]
6407 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
6409 *) Basic restructuring to introduce the MPM concept; includes various
6410 changes to the module API... better described by
6411 docs/initial_blurb.txt. [Dean Gaudet]
6413 Changes with Apache pthreads
6415 *) New buff option added: BO_TIMEOUT. It describes the timeout for
6416 buff operations (generally over a network).
6417 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
6419 *) Created http_accept abstraction. Added 4 new functions (not exported):
6420 init_accept(), begin_accepting_requests(), get_request(),
6421 stop_accepting_requests() [Bill Stoddard]
6423 *) Fix to ap_rprintf call that allows mod_info to work properly.
6424 [James Morris <jmorris intercode.com.au>]
6426 *) user and ap_auth_type fields were moved from connection_rec to
6427 request_rec. [Ryan Bloom]
6429 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
6430 needed in a threaded server.
6432 *) Initial pthread implementation from from Dean's apache-nspr code.
6433 [Bill Stoddard, Ryan Bloom]
6436 Changes with Apache 1.3.9
6438 *) Remove bogus error message when a redirect doesn't set Location.
6439 Instead, use an empty string to avoid coredump if the error message
6440 was supposed to include a location. [Roy Fielding]
6442 *) Don't allow configure to include mod_auth_digest unless it is
6443 explicitly requested, even if the user asked for all modules.
6446 *) Translate module names to dll names for OS/2 so that they are no more
6447 than 8 characters long and have an extension of "dll" instead of "so".
6450 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
6451 Fix test-compile check to check for randbyte instead of trand32.
6452 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
6453 and tweak to make Amaya happier. [Ronald Tschalär]
6455 *) Ensure that the installed expat include files are world readable,
6456 just like the other header files. [Martin Kraemer]
6458 *) Fixed generated AddModule adjustments in APACI's `configure' script
6459 in order to allow (new) modules like mod_vhost_alias to be handled
6460 correctly (which was touched by the adjustments for mod_alias).
6461 [Ralf S. Engelschall]
6463 *) For binary builds, add -R flag to apachectl to work around the lack of
6464 an absolute path to the ./libexec directory where the libhttp.ep file
6465 is needed for SHARED_CORE architectures. [Randy Terbush]
6467 *) WIN32: Create the CGI script process as DETACHED. This may solve the
6468 problem observed by some Win95/98 users where they get CGI script
6469 output sent to the console. [Bill Stoddard]
6471 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
6472 routines are now called ap_base64* and are 'plain' (i.e., no
6473 pool access or anything clever). Inside util.c the routines acting
6474 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
6475 The oddly named ap_uuencode(), ap_uudecode() are kept around for
6476 now but deprecated. [dirkx]
6478 *) Clean up the base64 and SHA1 additions and make sure they are
6479 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
6480 files. [Roy Fielding]
6482 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
6483 checking. Allow compiling on VS 6.0. [Randy Terbush]
6485 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
6487 *) Use TestCompile to search for the truerand library (rather than blindly
6488 assuming its existence). If it is not found, complain (but do not
6489 exit - yet). [Martin Kraemer]
6491 *) We forgot to add the new exported function names to
6492 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
6494 *) Add description of -T command-line option to usage().
6495 [Ralf S. Engelschall]
6497 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
6498 searched only AFTER libap has been searched, because libap needs
6499 some symbols from libos. [Martin Kraemer]
6501 *) Fix conflict with original mod_digest related to the symbol of the
6502 module dispatch list (which has to be unique for DSO and follow the
6503 usual conventions for the installation procedure).
6504 [Ralf S. Engelschall]
6506 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6507 for other platforms as well. [Martin Kraemer]
6509 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6510 types by AP_LONG and replace reference to renamed variable 'ubuf'
6511 by 'buffer'. [Martin Kraemer]
6513 Changes with Apache 1.3.8 [not released]
6515 *) Flush the output buffer immediately after sending an error or redirect
6516 response, since the result may be needed by the client to abort a
6517 long data transfer or restart a series of pipelined requests.
6518 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
6520 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6521 [Ian Turner <iant sequent.com>] PR#4735
6523 *) Local struct mmap in http_core.c conflicted with system structure
6524 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6526 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6527 [Ronald Tschalär <ronald innovation.ch>]
6529 *) Fix a memory leak where the module counts were getting messed
6530 up across restarts. [David Harris <dharris drh.net>]
6532 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6533 properly in mod_access.
6534 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
6536 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6537 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
6539 *) PORT: Support for compaq/tandem/com.
6540 [Michael Ottati <michael.ottati compaq.com>, dirkx]
6542 *) Added SHA1 password encryption support to easy migration from
6543 Netscape servers. See support/SHA1 for more information.
6544 Caused the separation of ap_md5.c into md5, sha1 and a general
6545 ap_checkpass.c with just a validate_passwd routine. Added a
6546 couple of flags to support/htpasswd. Some reuse of the to64()
6547 function; hence renamed to ap_to64().
6548 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
6550 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6551 with ASCII/EBCDIC conversions in "ident" query.
6552 [David McCreedy <McCreedy us.ibm.com>]
6554 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6555 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6556 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6558 *) Fix SIGSEGV on some systems because the Vary fix below included
6559 a call to table_do with a variable argument list that was not
6560 NULL terminated. Replaced with better implementation. [Roy Fielding]
6562 Changes with Apache 1.3.7 [not released]
6564 *) The "Vary" response header field is now sanitised right before
6565 the header is sent back to the client. Multiple "Vary" fields
6566 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6567 "Vary: host, negotiate, host, accept-language") are reduced to
6568 single instances. This is a better solution than the force-no-vary
6569 one (which is still valid for clients that can't cope with Vary
6570 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6572 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
6574 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6575 least on Linux and FreeBSD for now.
6578 *) Win32: More apache -k restart work. Restarts are now honored
6579 immediately and connections in the listen queue are -not- lost.
6580 This is made possible by the use of the WSADuplicateSocket()
6581 call. The listeners are opened in the parent, duplicated, then
6582 the duplicates are passed to the child. The original listen sockets
6583 are not closed by the parent across a restart, thus the listen queue
6585 [Bill Stoddard <stoddard raleigh.ibm.com>]
6587 *) Fix handling of case when a client has sent "Expect: 100-continue"
6588 and we are going to respond with an error, but get stuck waiting to
6589 discard the body in the pointless hope of preserving the connection.
6590 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
6592 *) Fix 'configure' to work correctly with SysV-based versions of
6593 'tr' (consistent with Configure's use as well). [Jim Jagielski]
6595 *) apxs: Add "-S var=val" option which allows for override of CFG_*
6596 built-in values. Add "-e" option which works like -i but doesn't
6597 install the DSO; useful for editing httpd.conf with apxs. Fix
6598 editing code so that multiple invocations of apxs -a will not
6599 create duplicate LoadModule/AddModule entries; apxs can now be
6600 used to re- enable/disable a module. [Wilfredo Sanchez]
6602 *) Win32: Update the server to use Winsock 2. Specifically, link with
6603 ws2_32.lib rather than wsock32.lib. This gives us access to
6604 WSADuplcateSocket() in addition to some other enhanced comm APIs.
6605 Win 95 users may need to update their TCP/IP stack to pick up
6606 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
6607 [Bill Stoddard <stoddard raleigh.ibm.com>]
6609 *) Win32: Redirect CGI script stderr (script debug info) into the
6610 error.log when CGI scripts fail. This makes Apache on Win32
6611 behave more like Unix.
6612 [Bill Stoddard <stoddard raleigh.ibm.com>]
6614 *) Fixed `httpd' usage display: -D was missing.
6615 [Ralf S. Engelschall] PR#4614
6617 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
6618 [Ralf S. Engelschall] PR#4561, PR#4562
6620 *) OS/2: Fix problem with accept lock semaphores where server would die with
6621 "OS2SEM: Error 105 getting accept lock. Exiting!"
6622 [Brian Havard] PR#4505
6624 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
6625 [Randy Terbush <randy covalent.net>]
6627 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
6628 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
6630 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
6631 command potentially _is_ GCC. [Ralf S. Engelschall]
6633 *) Fix apxs build issues on AIX
6634 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
6636 *) DocumentRoot Checking: Under previous versions, when Apache
6637 first started up, it used to do a stat of each DocumentRoot to
6638 see if it existed and was a directory. If not, then an error
6639 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
6640 does not exist, you will get error messages in error_log. If
6641 the '-t' command line option is used (to check the configuration)
6642 the check of DocumentRoot IS performed. An additional command
6643 line option, '-T', has been added if you want to avoid the
6644 DocumentRoot check even when checking the configuration.
6647 *) Win32: The query switch "apache -S" didn't exit after showing the
6648 vhost settings. That was inconsistent with the other query functions.
6649 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
6651 *) Win32: Changed behaviour of apache -k restart.
6652 Previously, the server would drain all connections in the stack's
6653 listen queue before honoring the restart. On a busy server, this
6654 could take hours. Now, a restart is honored almost immediately.
6655 All connections in Apache's queues are handled but connections in
6656 the stack's listen queue are discarded. Restart triggered by
6657 MaxRequestPerChild is unchanged.
6658 [Bill Stoddard <stoddard raleigh.ibm.com>]
6660 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
6661 the accept loop. Good for a 5% performance boost. Cleaned up
6662 parent/child process management code.
6663 [Bill Stoddard <stoddard raleigh.ibm.com>]
6665 *) Added ceiling on file size for memory mapped files.
6666 [John Giannandrea <jg meer.net>] PR#4122
6668 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
6669 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
6670 [Henri Gomez <gomez slib.fr>, Ralf S. Engelschall]
6672 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
6673 use this at least for Expat. [Ralf S. Engelschall]
6675 *) Allow .module files to specify libraries with Lib:.
6678 *) Allow SetEnvIf[NoCase] to test environment variables as well
6679 as header fields and request attributes. [Ken Coar]
6681 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
6682 content-types are "text/html;parameters". PR#4524 [Ken Coar]
6684 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
6685 never accepted into any standard, and it opens up certain DoS
6686 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
6688 *) TestCompile updated. We can now run programs and output the
6689 results during the Configure process. [ Jim Jagielski]
6691 *) The source is now quad (long long) aware as needed. Specifically,
6692 the Configure process determines the correct size of off_t and
6693 *void. When the OS/platform/compiler supports quads, ap_snprintf()
6694 provides for the 'q' format qualifier (if quads are not available,
6695 'q' is silently "demoted" to long). [Jim Jagielski]
6697 *) When the username or password fed to htpasswd is too long, include the
6698 size limit in the error message. Also report illegal characters
6699 (currently only ':') in the username. Add the size restrictions
6700 to the man page. [Ken Coar]
6702 *) Fixed the configure --without-support option so it doesn't result in
6703 an infinite loop. [Marc Slemko]
6705 *) Piped error logs could cause a segfault if an error occured
6706 during configuration after a restart.
6707 [Aidan Cully <aidan panix.com>] PR#4456
6709 *) If a "Location" field was stored in r->err_headers_out rather
6710 than r->headers_out, redirect processing wouldn't find it and
6711 the server would core dump on ap_escape_html(NULL). Check both
6712 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
6713 if Location isn't set. [Doug MacEachern, Ken Coar]
6715 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
6716 of the Expat 1.0.2 distribution. [Greg Stein]
6718 *) Replace regexec() calls with calls to a new API stub function
6719 ap_regexec(). This solves problems with DSO modules which use the regex
6720 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]
6722 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
6723 environment variables can be set according to the protocol version
6724 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
6726 *) Add DSO support for OpenStep (Mach 4.2) platform.
6727 [Ralf S. Engelschall, Rex Dieter <rdieter math.unl.edu>] PR#3997
6729 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
6730 [Jan Gallo <gallo pvt.sk>] PR#3690, PR#4373
6732 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
6733 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
6735 *) Better DSO flags recognition on NetBSD platforms using ELF.
6736 [Todd Vierling <tv pobox.com>] PR#4310
6738 *) Always log months in english format for %t in mod_log_config.
6739 [Petr Lampa <lampa fee.vutbr.cz>] PR#4366, 679
6741 *) Support for server-parsed and multiview-determined ReadmeName and
6742 HeaderName files in mod_autoindex. Removed the restriction on
6743 "/"s in ReadmeName and HeaderName directives since the *sub_req*
6744 routines will deal with the access issues. (It's now possible to
6745 have {site|group|project|customer|...} wide readmes and headers.)
6746 [Raymond S Brand <rsbx rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
6749 *) When stat() fails, don't assume anything about the contents of
6750 the struct stat. [Ed Korthof <ed bitmechanic.com>]
6752 *) It's OK for a semop to return EINTR, just loop around and try
6753 again. [Dean Gaudet]
6755 *) Fix configuration engine re-entrant hangups, which solve a
6756 handful of problems seen with mod_perl <Perl> configuration sections
6757 [Salvador Ortiz Garcia <sog msg.com.mx>]
6759 *) Mac OS and Mac OS X Server now use the appropriate custom layout
6760 by default when building with APACI; allow for platform-specific
6761 variable defaults in configure. [Wilfredo Sanchez]
6763 *) Do setgid() before initgroups() in http_main; some platforms

6781 being newer than Configuration so that it is less likely to fail
6782 when using APACI and shadow sources. [Wilfredo Sanchez]
6784 *) PORT: Add initial support for Mac OS (versions 10.0 and
6785 greater). Use Mac OS X Server layout for now. Clean up dyld code
6786 in unix/os.c, and don't install the dyld error handlers, which
6787 are no longer needed in Mac OS. [Wilfredo Sanchez]
6789 *) Rename Rhapsody layout to "Mac OS X Server". Change install
6790 locations to appropriate ones for user-built (as opposed to
6791 system) installs. [Wilfredo Sanchez]
6793 *) Modify mod_autoindex's handling of AddDescription so that the
6794 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
6796 *) Add functionality to the install-bindist.sh script created by
6797 binbuild.sh to use tar when copying distribution files to the
6798 serverroot. This allows upgrading an existing installation
6799 without nesting the new distribution in the old.
6801 install-bindist.sh now detects the local perl5 path to install
6802 apxs and dbmmanage with proper path to perl interpreter.
6804 Add an install-binsupport target which copies the source files
6805 for apxs and dbmmanage to bindist to allow these scripts to
6806 be properly installed relative to the destination serverroot.

6834 value of the DirectoryIndex directive is a single dot. Also likely
6835 to happen for anyother values of DirectoryIndex that will map back

6922 *) Correct an apparent typo: on the Windows and MPE platforms, the
6923 htpasswd utility was limiting passwords to only 8 characters.
6926 *) EBCDIC platforms: David submitted patches for two bugs in the
6927 MD5 digest port for EBCDIC machines:
6928 a) the htdigest utility overwrote the old contents of the digest file
6929 b) the Content-MD5 header value (ContentDigest directive) was wrong
6930 when the returned file was not converted from EBCDIC, but was a
6931 binary (e.g., image file) in the first place.
6932 [David McCreedy <mccreedy us.ibm.com>]
6934 *) support/htpasswd now permits the password to be specified on the

6970 mismatches were causing compilation problems with gcc -pedantic and

6973 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
6974 a roughly 5 fold speed up. [Brian Havard]
6976 *) proxy ftp: instead of using the hardwired string "text/plain" as
6977 a fallback type for files served by the ftp proxy, use the
6978 ap_default_type() function to determine the configured type.
6979 This allows for special configurations like
6980 <Directory proxy:ftp://some.host>
6981 DefaultType gargle/blurb
6983 Additionally, add the Content-Encoding: header to FTP proxy replies
6984 when the encoding is defined (by the AddEncoding directive).
6985 Because it was missing, it was almost impossible to browse compressed
6986 files using the FTP proxy (works now perfectly in Communicator).
6987 The ftp proxy now also returns the Date: and Server: header lines (if not
6988 much else... This code is "somewhat" broken) like normal requests do.
6991 *) Be more smart in APACI's configure script when determining the UID/GID
6992 for User/Group directives and use the determined UID/GID to initialize
6993 the permissions on the proxycachedir.
6994 [Dirk-Willem van Gulik, Ralf S. Engelschall]
6996 *) Changed the forking-prior-to-cleanup in the proxy module to first
6997 check wether it actually needs to collect garbage. This reduces
6998 the number of fork()s from one/request to just the odd one an hour.
6999 [Dirk-Willem van Gulik]

7028 *) M_INVALID needed a value within the scope of METHODS so that unknown
7029 methods can be access controlled. [Roy Fielding] PR#3821
7031 *) Added PassAllEnv; makes server's entire environment available
7032 to CGIs and SSIs executed within directive's scope. [Ken Coar]
7034 *) ap_uuencode() always added two trailing '='s and encoding of
7035 8 bit characters on a machine with signed char may produced
7036 incorrect results. Additionally ap_uuencode() should now
7037 work correctly on EBCDIC platforms.
7038 [Ronald Tschalär <ronald innovation.ch>] PR#3411
7040 *) WIN32: Binary installer now runs the configuration DLL before
7041 the reboot prompt (which is only given if MSVCRT.DLL system
7042 DLL is new or updated). This should avoid the configuration
7043 directory being empty after installation. [Paul Sutton]
7044 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

7048 the Apache service on NT. [Paul Sutton] PR#3741
7050 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
7052 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
7053 have been reported with flock() locking (probably related to kernel
7054 version). [Dean Gaudet] PR#2723, 3531
7056 *) Using APACI, the main config file (usually httpd.conf) was
7057 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez

7067 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
7068 for 8-bit safeness. [Dean Gaudet]
7070 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
7071 because SPARCs have a small machine-specific maximum size for the Global
7072 Offset Table which is often exceeded when compiling one of the larger
7073 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977
7075 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
7076 DSO/DLL section because it's a directive from mod_status and isn't
7077 available before the DLL of mod_status is loaded.

7092 *) Let APACI's configure script correctly complain for unknown --enable-XXX
7093 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
7095 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
7096 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
7097 possible buffer overflows. [Ralf S. Engelschall]
7099 *) Remove no longer used non-API function ap_single_module_init().
7100 [Ralf S. Engelschall]
7102 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
7105 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
7106 to make platform installations easier. [Wilfredo Sanchez]
7108 *) In configure, do not append the target name to the directory path if
7109 the path already contains "apache". [Ralf S. Engelschall]
7111 *) SIGPIPE is now ignored by the server core. The request write routines
7112 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
7113 correctly check for output errors and mark the connection as aborted.
7114 Replaced many direct (unchecked) calls to ap_b* routines with the
7115 analogous ap_r* calls. [Roy Fielding]
7117 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
7118 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
7119 Furthermore map lookups for non-existent keys are now cached as well.
7120 Additionally "txt" maps are now parsed with simple string functions
7121 instead of using ap_pregcomp(). As a side effect a bug that prevented
7122 the usage of keys containing the "," character was fixed.
7123 The changes drastically improve the performance when large rewrite maps
7125 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
7127 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
7128 other than GET, and const'd the definition of method in request_rec.
7131 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
7133 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
7134 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
7136 *) Add %V to mod_log_config, this logs the hostname according to the
7137 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
7138 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
7140 *) Add support for \n and \t to mod_log_config, can be used to produce
7141 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
7143 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
7145 *) Added informative error messages for failed munmap() and fseek() calls
7146 in http_core.c. [John Bley, Roy Fielding]
7148 *) Added some informative error messages for some failed malloc()
7149 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
7151 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
7152 is removed. This allows <Directory proxy:*> directives to work and
7153 prevents invalid requests from killing the process.
7154 [Brian Havard <brianh kheldar.apana.org.au>]
7156 *) Reorganised FAQ document.
7157 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497
7159 *) src/support/: The ApacheBench benchmark program was overhauled by
7160 David N. Welton: you can now have it generate an HTML TABLE, presumably
7161 for integration into other HTML sources. David updated the ab man page
7162 as well and added some missing descriptions. Thanks!
7163 [David N. Welton <davidw prosa.it>]
7165 *) Win32: The filename validity checker now allows filenames containing
7166 characters in the range 0x80 to 0xff (for example accented characters).
7167 [Paul Sutton] PR#3890
7169 *) Added conditional logging based upon environment variables to
7170 mod_log_config. mod_log_referer and mod_log_agent
7171 are now deprecated. [Ken Coar]
7173 *) Allow apache acting as a proxy server to relay the real
7174 reason of a failure to a client rather than the "internal
7175 server error" it does currently. The general exposure mechanism
7176 can be triggered by any module by setting the "verbose-error-to"
7177 note to "*"; this allows more than just proxy errors to be exposed.
7178 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
7180 *) Moved man pages for ab and apachectrl to section 8.
7181 [Wilfredo Sanchez, Roy Fielding]
7183 *) Added -S option to install.sh so that options can be passed to
7184 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
7186 *) Tweak modules Makefile generated by Configure so that it handles
7187 the test case of no modules being selected. [<chaz reliant.com>]
7189 *) Added a <LimitExcept method ...> sectioning directive that allows
7190 the user to assign authentication control to any HTTP method that
7191 is *not* given in the argument list; i.e., the logical negation
7192 of the <Limit> directive. This is particularly useful for controlling
7193 access on methods unknown to the Apache core, but perhaps known by
7194 some module or CGI script. [Roy Fielding, Tony Finch]
7196 *) Prevent apachectl from complaining if the PIDFILE exists but
7197 does not contain a process id, as might occur if the server is
7198 being rapidly restarted. [Wilfredo Sanchez]
7200 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
7202 *) Entity tag comparisons for If-Match and If-None-Match were not being
7203 performed correctly -- weak tags might cause false positives. Also,
7204 strong comparison wasn't properly enforced in all cases.
7205 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
7207 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
7210 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
7211 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
7213 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
7214 to util.c for parsing an HTTP header field value to extract the next
7215 list item, taking into account the possible presence of nested comments,
7216 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
7217 insignificant whitespace and lowercases non-quoted tokens.
7218 [Roy Fielding] PR#2065
7220 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
7221 code different from 500. This allows the proxy to, e.g., return
7222 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
7224 *) Fix ordering of language variants for the case where the traditional
7225 negotiation algorithm is being used with multiple language variants
7226 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
7228 *) Do not round the TCN quality calculation to 5 decimal places,
7229 unlike RFC 2296, because the calculation might need 12 decimal places
7230 to get the right result. [Roy Fielding]
7232 *) Remove unused code to disable transparent negotiation when
7233 negotiating on encoding only, as we now handle encoding too
7234 (though this is nonstandard for TCN), remove charset=ISO-8859-1
7235 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
7236 some debugging statements within mod_negotiation. [Koen Holtman]
7238 *) Fixed a rare memory corruption possibility in mod_dir if the index
7239 file is negotiable and no acceptable variant can be found.
7240 [Dean Gaudet, Roy Fielding, Martin Kraemer]
7242 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
7243 searching the Win32 registry for script interpreters.
7246 *) Win32: The compiled-in default filename for the error log is now
7247 error.log, which matches the default in the distributed httpd.conf.
7250 *) Win32: Any error messages from -i or -u command line options are now
7251 displayed on the console output rather than sent to the error log.
7252 Also the "Running Apache..." message is not output unless Apache is
7253 going to serve requests. [Paul Sutton]
7255 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
7256 and use a private significator ('$apr1$') to mark passwords as
7257 being smashed with our own algorithm. Also abstract the password
7258 checking into a new ap_validate_password() routine. [Ken Coar]
7260 *) Win32: The filename validity checker now allows "COM" but refuses
7261 access to "COM1" through "COM4". This allows filenames such
7262 as "com.name" to be served. [Paul Sutton] PR#3769.
7264 *) BS2000: Adapt to the new ufork() system call interface which will
7265 make subtasking easier on the OSD/POSIX mainframe environment.
7268 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
7269 ap_compat.h. [David White <david persimmon.com>] PR#3725
7271 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
7272 use `.db' instead of `.pag' not only for FreeBSD, but also when
7273 the NDBM library looks like Berkeley-DB based.
7274 [Ralf S. Engelschall] PR#3773

7289 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
7290 and check to see if the tar we wind up with supports '-h'.
7291 [Jim Jagielski] PR#3671
7293 *) A consistent and conservative style for all shell scripts has been
7294 implemented. Basically, all shell string tests use the traditional
7295 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
7296 to protect against bare null variable strings (ie: wrapping both
7297 sides with double quotes and prepending 'x'). 'x' was chosen
7298 because it's more universal and hopefully easier for old shell
7299 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
7302 *) The status module now prints out both the main server generation as
7303 well as the generation of each process. Also, the vhost info is
7304 printed with '?notable'. [Jim Jagielski]
7306 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
7307 and this makes its functions available to things in src/support.
7310 Changes with Apache 1.3.4
7312 *) Renamed macros status_drops_connection to ap_status_drops_connection
7313 and vestigial scan_script_header to ap_scan_script_header_err,
7314 mostly for aesthetic reasons. [Roy Fielding]
7316 *) The query switch "httpd -S" didn't exit after showing the
7317 vhost settings. That was inconsistent with the other query functions.
7320 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
7321 filename to the end of the STANDARD_MODULE_STUFF. Its
7322 presence at the beginning prevented reporting of the filename
7323 for modules compiled before 1 January 1999. [Ken Coar]
7325 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
7326 to detect and prevent access to special DOS device file names.
7327 [Paul Sutton, Ken Parzygnat]
7329 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
7330 and Makefile_win32_debug.txt (debug build) that work on Win95.
7331 Run each of the following from the src directory:
7332 nmake /f Makefile_win32.txt # compiles normal build
7333 nmake /f Makefile_win32.txt install # compiles and installs
7334 nmake /f Makefile_win32.txt clean # removes compiled junk
7335 nmake /f Makefile_win32_debug.txt # compiles debug build
7336 nmake /f Makefile_win32_debug.txt install
7337 nmake /f Makefile_win32_debug.txt clean
7340 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
7341 to build binary distributions. [Lars Eilebrecht]
7343 *) IndexOptions SuppressColumnSorting only turned off making
7344 the column headers anchors; you could still change the display
7345 order by manually adding a '?N=A' or similar query string to the
7346 URL. Now SuppressColumnSorting locks in the sort order so
7347 it can't be overridden this way. [Ken Coar]
7349 *) Added IndexOrderDefault directive to supply a default sort order
7350 for FancyIndexed directory listings. [Ken Coar] PR#1699
7352 *) Change the ap_assert macro to a variant that works on all platforms.
7353 [Richard Prinz <richard.prinz cso.net>] PR#2575
7355 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
7356 search for an underscore on dlsym() (as it's already the case
7357 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
7359 *) Small fix for mod_env.html: The module was documented as to be _not_
7360 compiled into Apache per default, although it _IS_ compiled into
7361 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
7363 *) Instead of fixing a bug in the generation procedure for config.status (a
7364 backslash was missing) we remove the bug together with it's complete
7365 context because the special cases of the past can now no longer occur
7366 because of the recent magic for the --with-layout default.
7367 [Ralf S. Engelschall] PR#3590
7369 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
7370 making sure the src/support/ tools are _forced_ to be build last (they
7371 depend on other libraries).
7372 [Markus Theissinger <markus.theissinger gmx.de>]
7374 *) Fix installation procedure: Now that os-inline.c is actually used (a
7375 recently fixed bug prevented this) we need to also install os-include.c
7376 in addition to os.h into the PREFIX/include/ location or building of
7377 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
7379 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
7380 allow us to distinguish between a garbled DSO (or even a file which isn't
7381 an Apache module DSO at all) and a DSO which doesn't match the current
7382 Apache API. [Ralf S. Engelschall] PR#3152
7384 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
7385 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
7386 match case insensitive (this especially avoids nasty patterns like
7387 `[tT][eE][sS][tT]'). Second two additional internal map functions
7388 `escape' and `unescape' were added which can be used to escape/unescape
7389 to/from hex-encodings in URLs parts (this is especially useful in
7390 combination with map lookups).
7391 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
7393 *) Renamed the macro escape_uri() to ap_escape_uri() which was
7394 forgotten (because it was a macro) in the symbol renaming process.
7395 [Ralf S. Engelschall]
7397 *) Fix some inconsistencies related to the scopes of directives. The only
7398 user visible change is that the directives `UseCanonicalName' and
7399 `ContentDigest' now use the (more correct) `Options' scope instead of
7400 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
7402 *) Using DSO, the Server token was being mangled. Specifically, the
7403 module's token was being added first before the Apache token. This
7404 has been fixed. [Jim Jagielski]
7406 *) Major overhaul of mod_negotiation.c, part 2.
7407 - properly handle "identity" within Accept-Encoding.
7408 - allow encoded variants in RVSA negotiation and let them appear in
7409 the Alternates field using the non-standard "encoding" tag-list.
7410 - fixed both negotiation algorithms so that an explicitly accepted
7411 encoding is preferred over no encoding if "identity" is not
7412 included within Accept-Encoding.
7413 - added ap_array_pstrcat() to alloc.c for efficient concatenation
7414 of large substring sequences.
7415 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
7418 *) Major overhaul of mod_negotiation.c, part 1.
7419 - cleanups to mod_negotiation comments and code structure
7420 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
7421 support for everything in the upcoming HTTP/1.1
7422 revision (draft-ietf-http-v11-spec-rev-06.txt).
7423 - language tag matching also handles tags with more than 2
7425 - empty Accept, Accept-Language, Accept-Charset headers are
7426 processed correctly; previously an empty header would make all
7427 values acceptable instead of unacceptable.
7428 - allowed for q values in Accept-Encoding
7429 - added support for transparent content negotiation (rfc2295 and
7430 rfc2296) (though we do not implement all features in these drafts,
7431 e.g. no feature negotiation). Removed old experimental version.
7432 - implemented 'structured entity tags' for better cache correctness
7433 (structured entity tags ensure that caches which can deal with Vary
7434 will (eventually) be updated if the set of variants on the server
7436 - this involved adding a vlist_validator element to request_rec
7437 - this involved adding the ap_make_etag() function to the global API
7438 - modified guessing of charsets used by Apache negotiation algorithm
7439 to guess 'no charset' if the variant is not a text/* type
7440 - added code to sort multiviews variants into a canonical order so that
7441 negotiation results are consistent across backup/restores and mirrors
7442 - removed possibility of a type map file resolving to another type map
7443 file as its best variant
7444 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
7446 *) RFC2396 allows the syntax http://host:/path (with no port number)
7447 but the proxy disallowed it (ap_proxy_canon_netloc()).
7448 [David Kristol <dmk bell-labs.com>] PR#3530
7450 *) When modules update/modify the file name in the configfile_t structure,
7451 syntax errors will report the updated name, not the original one.
7452 [Fabien Coelho <coelho cri.ensmp.fr>] PR#3573
7454 *) Correct some filename case assumptions from WIN32 to
7455 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
7457 *) For %v log ServerName regardless of the UseCanonicalName
7458 setting (similarly for %p). [Dean Gaudet]
7460 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
7461 rather late (too late for some invocations of TestCompile).
7462 This improves the make environment available to TestCompile and
7463 the *.module scripts. [Martin Kraemer]
7465 *) The hashbang emulation code in ap_execve.c would interpret
7466 #!/hashbang/scripts correctly, but failed to fall back to a
7467 standard shell for scripts which did NOT start with #!
7468 Now SHELL_PATH is started in these cases. [Martin Kraemer]
7470 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
7473 *) Update APXS manual page: some -q option arguments were missing
7474 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
7476 *) Cleanup the command line options: `-?' was documented to show
7477 the usage list but does it with an error because `?' is not a valid
7478 command. OTOH a lot of users expect `-h' to print such a usage list and
7479 instead are annoyed for ages by our huge unreadable list of directives.
7480 So we now changed the command line options this way:
7482 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
7483 very similar to the popular linker option.
7485 Intent: while -l gives the small list of modules, -L now gives the
7486 large list of directives implemented by these modules. This is also
7487 consistent with -v (short version info) and -V (large version info).
7489 Intent: it's now the expected option ;-)
7490 The manual page was adjusted accordingly.
7491 [Ralf S. Engelschall] PR#2714
7493 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
7494 wasn't defined. [Rick Franchuk <rickf transpect.net>]
7496 *) Removed recently introduced bugs and disfigurements in APACI:
7497 o fixed argument line processing: using $args was broken: It was not
7498 initialized and using args="$args $apc_option" and even args="$args
7499 \"$apc_option\"" fails in the second processing round for any arguments
7500 containing whitespaces. The only correct way is to use the construct
7501 "$@" (but not possible here) or iterate _both_ times over the implicit
7502 argument line (no argument to for-loop) which is what we now use.
7503 o make --with-layout=Apache the default without creating
7504 redundancy (copying the --with-layout block in the argument parsing
7505 loop). We achieve this by using the "$@" construct together with the
7506 `set' command to prepend --with-layout=Apache to the command line in
7507 case --with-layout is not used.
7508 o fixed auto-suffix handling now that config.layout exists.
7509 Paths which are auto-suffixed are marked with a trailing plus sign in
7510 config.layout and every path now can be marked this way (not only the
7511 four paths for which we do it currently). Additionally the suffix is
7512 no longer a static one. Instead it's now `/<target>' where <target> is
7513 the argument of the --target option or per default `httpd'.
7514 o allow also tabs (and only spaces) where we match whitespaces
7515 o various fixes and cleanups related to used shell coding style
7516 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7517 o trimmed output of --help to fit into 80 columns
7518 [Ralf S. Engelschall]
7520 *) Added two new core API functions, ap_single_module_configure() and
7521 ap_single_module_init(), which are now used by mod_so to configure a module
7522 after loading. [Ralf S. Engelschall]
7524 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
7525 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
7526 of ap_config.h to allow serialized accept for multiport listens.
7527 [Roy Fielding, Curt Sampson] PR#3120
7529 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
7530 of ap_config.h that would skip several defines if DEFAULT_GROUP
7531 was overridden. [Roy Fielding]
7533 *) PORT: The I86 version of DGUX has support for strncasecmp and
7534 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
7536 *) Fix ordering of definitions in ap_config.h so that ap_inline is
7537 defined before it might be used. [Victor Khimenko]
7539 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
7540 [Tom Serkowski <tks bsdi.com>] PR#3453
7542 *) Make generation of src/Configuration.apaci more robust: It failed to
7543 differenciate between modules when one module name was a postfix of
7544 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
7545 just XXX (think about totally non-standard names like "apache_ssl", too).
7546 [Ralf S. Engelschall] PR#3380
7548 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
7549 since 1.3b7) and make whitespace handling more robust (it failed horrible
7550 when whitespaces were present in the arguments of -D options).
7551 [Ralf S. Engelschall] PR#3240
7553 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
7554 creates an external package shadow tree in DIR before the local build
7555 shadow tree is generated under DIR. This way one can have the extracted
7556 Apache distribution tree read-only on NFS or CDROM and still build Apache
7557 from these sources. An automatically triggered VPATH-like mechanism is
7558 provided through the TOP variable, too.

7562 generated when, for a particular dimension, variants only vary
7563 in having or not having a value for that dimension. [Paul Sutton]

7566 unencoded variant if the user-agent explicitly says it can
7567 accept that encoding. Previously we always preferred the unencoded

7572 and the usage page was inconsistent with the functionality and manpage.

7575 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
7576 They can occur multiple times and their arguments (`xxx') are passed AS
7577 IS to the compiler/linker command. [Ralf S. Engelschall]
7579 *) Fixed possible (but harmless in practice) bug in the DBM lookup
7580 procedure of mod_rewrite: very long keys were truncated.
7581 [Ralf S. Engelschall]
7583 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
7584 identifier, currently "Apache" and "GNU" are pre-defined in the file
7585 config.layout. Custom layouts are possible by using FILE:ID as the
7586 argument where the layout ID is taken from FILE.
7588 The config.layout file consists of <Layout ID>..</Layout> sections
7589 where inside those sections "path_variable: path_value" pairs can be
7590 specified. These lines are converted to path_variable='path_value'.
7592 *) Add a DefaultLanguage directive so that files missing a language
7593 extension (e.g., .fr, .de) can be labelled as being some other
7594 default language. DefaultLanguage can appear in <Directory> and
7595 <Files> containers as well as .htaccess files. [Paul Sutton]
7598 *) Fix TARGET configuration when configuring and installing using
7599 APACI configure. TARGET now defines the basename of the configuration
7600 file, startup script, manual page, etc. log_error_core() now reports
7601 the server binary name given by argv[0]. TARGET can now also be defined
7602 with --target=TARGET parameter passed to APACI configure.
7603 [Ralf Engelschall, Randy Terbush]

7711 supported for the option argument: first BEGIN:foo which permutes module
7712 mod_foo with the begin of the module list, i.e. it `moves' the module to
7713 the begin of the list (gives it lowest priority). And second foo:END

7766 in mod_auth if we know that we know that no other module can
7767 deal with it. [Marc Slemko]
7769 *) Remove ap_private_extern method of hiding conflicting symbols
7770 on the NEXT platform because it is not correct for all versions,
7771 and the versions for which it is correct are unknown.
7772 [Wilfredo Sanchez <wsanchez apple.com>]
7774 *) Fix inheritance of IndexOptions NameWidth and remove unintended
7775 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
7777 *) Fix per-directory config merging for cases in which a 500 error
7778 is encountered in an .htaccess file somewhere down the tree.
7781 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
7783 *) Fixed a segmentation violation in mod_proxy when a response is
7784 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
7786 Changes with Apache 1.3.3
7788 *) Added a complete implementation of the Expect header field as
7789 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
7790 response when we already know the final status, which is mighty
7791 useful for PUT responses that result in 302 or 401. [Roy Fielding]
7793 *) Remove extra trailing whitespace from the getline results as part
7794 of the protocol processing, which is extra nice because it works
7795 between continuation lines, is almost no cost in the normal case
7796 of no extra whitespace, and saves memory. [Roy Fielding]
7798 *) Added new HTTP status codes and default response bodies from the
7799 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
7800 HTTP Extension Framework (510) specifications. Did not add the
7801 WebDAV 424 and 425 codes because they are bogus. We don't use any
7802 of these codes yet, but they are now available to 3rd-party modules.
7805 *) Fix a possible race condition between timed-out requests and the
7806 ap_bhalfduplex select that might result in an infinite loop on
7807 platforms that do not validate the descriptor. [Roy Fielding]
7809 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
7810 running Apache server [Paul Sutton]
7812 *) Fix mod_autoindex bug where directories got a size of "0k" instead
7813 of "-". [Martin Plechsmid <plechsmi karlin.mff.cuni.cz>, Marc Slemko]
7816 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker jetair.be>]
7818 *) Add the server signature text (from the core ServerSignature directive)
7819 to the list of envariables available to scripts, SSI, and the like.
7822 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
7823 [M. Laak <maert proinv.ee>] PR#3108
7825 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
7826 calculation in mod_status for all systems which don't have POSIX
7827 sysconf() (like UTS 2.1) and not only for the NEXT platform.
7828 [Dave Dykstra <dwd bell-labs.com>] PR#3055
7830 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
7831 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
7832 instead of ap_getword(..., ' ') (which parses only according to spaces
7833 but not tabs). [James Morris <jmorris intercode.com.au>,
7834 Ralf S. Engelschall] PR#3105
7836 *) Fix the SERVER_NAME variable under sub-request situations (where
7837 `UseCanonicalName off' is used) like CGI's called from SSI pages or
7838 RewriteCond variables by adopting r->hostname to sub-requests.

7852 *) PORT: Remove extra HAVE_SYS_RESOURCE_H define for RHAPSODY since
7853 it is now taken care of properly by the header file tests.
7854 [Wilfredo Sanchez <wsanchez apple.com>]
7856 *) Fix problem with scripts and filehandle inheritance on Win32.
7857 [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2884, 2910
7859 *) Win32 name canonicalisation could end up using the server's
7860 working directory to fill in some blanks. [Ken Parzygnat
7861 <kparz raleigh.ibm.com>] PR#3001
7863 *) Correct invalid assumption by ap_sub_req_lookup_file() that all
7864 absolute paths begin with "/" -- because they don't on Win32.
7865 [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2976, 3074
7867 *) Add [REDIRECT_]VARIANTS environment variable to mod_speling
7868 so that ErrorDocument 300 processors can reformat the list
7869 if desired. [Ken Coar] PR#2859
7871 *) Add +/- incremental prefixes to IndexOptions keywords, and
7872 enable merging of multiple IndexOptions directives. [Ken Coar]
7874 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
7875 <steve.cameron compaq.com>]
7877 *) Reconstructed the loop through multiple htaccess file names so
7878 that missing files are not confused with unreadable files.
7881 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
7882 errno on an error, which leads to one error being mistaken for
7883 another when reading non-existent .htaccess files.
7886 *) OS/2: The new header tests get things right, need to update
7887 ap_config.h. [Brian Havard]
7889 *) The Perl %ENV hash will now be setup by default when using the
7890 mod_include `perl' command [Doug MacEachern]
7892 *) PORT: Add Pyramid DC/OSx support to configuration mechanism.
7893 [Earle Ake <akee wpdiss1.wpafb.af.mil>]

7896 [Dave Dykstra <dwd bell-labs.com>] PR#3054
7898 *) Correct comment in mod_log_config.c about its internals.
7899 [Elf Sternberg <elf halcyon.com>]
7901 *) Avoid possible line overflow in Configure: Use an awkfile to
7902 handle the creation of modules.c [Jim Jagielski]
7904 Changes with Apache 1.3.2
7906 *) Fix bug in ap_remove_module(), which caused problems for dso's
7907 who were the top_module. [Doug MacEachern]
7909 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
7910 mod_auth_db to both be friendly to users who wants to use this version
7911 and to avoid problems under platforms where only version 2.x is present.
7912 [Dan Jacobowitz <drow false.org>, Ralf S. Engelschall]
7914 *) When using ap_log_rerror(), make the error message available to the
7915 *ERROR_NOTES envariables by default. [Ken Coar]
7917 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
7918 You now must define a BS2000Account name for the server User.
7919 This has fewer security implications than the old approach.
7922 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
7923 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
7924 platform to make the braindead HPUX linker happy. Notice, for the module
7925 DSOs we don't have to use this, because these are loaded manually (and
7926 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
7928 *) Remove 64 thread limit on Win32.
7929 [Bill Stoddard <stoddard raleigh.ibm.com>]
7931 *) Remove redundant substitutions in top-level Makefile.tmpl.
7932 [Ralf S. Engelschall]
7934 *) Fix APACI's `Group' configuration adjustment - especially for Linux
7935 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
7937 *) Make PrintPath work generically instead of having one version
7938 strictly for OS/2. [Jim Jagielski, Brian Havard]
7940 *) Fix the recently introduced C header file checking: We now use the C
7941 pre-processor pass only (and no longer the complete compiler pass) to
7942 determine whether a C header file exists or not. Because only this way
7943 we're safe against inter-header dependencies (which caused horrible
7944 portability problems). The only drawback is that we now have a CPP
7945 configuration variable which has to be determined first (we do a similar
7946 approach as GNU Autoconf does here). When all fails the user still has
7947 the possibility to override it manually via APACI or src/Configuration.
7948 As a fallback for the header check itself we can directly check the
7949 existance of the file under /usr/include, too.
7950 [Ralf S. Engelschall] PR#2777
7952 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
7953 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
7954 ap_private_extern defined to hide symbols that conflict with loaded
7955 dynamic libraries on the NEXT and RHAPSODY platforms.
7956 [Wilfredo Sanchez <wsanchez apple.com>]

7971 [Jeff Stewart <jws purdue.edu>] PR#2790
7973 *) Add some more LIBS for the SCO5 platform which are needed for the already
7974 used -lprot. It's actually a bug in SCO5, of course.
7975 [Ronald Record <rr sco.com>] PR#2533
7977 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
7978 trailing slash problem. [Jon Drukman <jsd gamespot.com>] PR#2933
7980 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
7981 platform, because it's only supported under version 4.0 and higher. But
7982 because our GuessOS is still unaware of Digital UNIX versions and the
7983 -msym is just to optimize the DSO statup time a little bit it's safe and
7984 best when we leave it out now. [Ralf S. Engelschall] PR#2969
7986 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
7987 functions: First all three functions no longer fail on strings containing
7988 "%" chars and second ap_log_printf() no longer does a double-formatting
7989 (instead it directly passes through the message to be formatted to the
7990 real internal formatting function). [Ralf S. Engelschall] PR#2941
7992 *) Allow "Include" directives anywhere in the server config
7993 files (but not .htaccess files). [Ken Coar] PR#2727
7995 *) The proxy was refusing to serve CONNECT requests except to
7996 port 443 (https://) and 563 (snews://). The new AllowCONNECT
7997 directive allows the configuration of the ports to which a
7998 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
8000 *) mod_expires will now act on content that is not sent from a file
8001 on disk. Previously it would never add an Expires: header to
8002 any response that did not come from a file on disk; the only
8003 case where it still doesn't (and can't) add one for that type of
8004 content is if you are using a modification date based setting.
8005 [Marc Slemko, Paul Phillips <paulp go2net.com>]
8007 *) Problems encountered during .htaccess parsing or CGI execution
8008 that lead to a "500 Server Error" condition now provide explanatory
8009 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
8012 *) Add NameWidth keyword to IndexOptions directive so that the
8013 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
8016 *) Recognize lowercase _and_ uppercase `uname' results under
8017 SCO OpenServer. [David Coelho <drc ppt.com>]
8019 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
8020 a common problem of (mis-administrated?) IIS servers, make the apache
8021 proxy immune to these errors (and ignore the duplicates, but log
8022 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
8024 *) The <IfModule and <IfDefine block starting directives now only
8025 allow exactly one argument. Previously, the optional negation
8026 character '!' could be separated by whitespace without a syntax
8027 error being reported, albeit defeating the IfModule functionality
8028 (enclosed directives would ALWAYS be executed). By using the
8029 stricter syntax, these hard-to-track errors can be avoided.
8032 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
8033 cause the standalone FancyIndexing directive to logically OR
8034 into any existing IndexOptions settings rather than wiping
8035 them out. [Ken Coar]
8037 *) Changes in ftp proxy: make URL parsing simpler by using the
8039 + Add display of the "current directory" in cases where it's
8040 different from the supplied path (e.g., ftp://user@host/ lives
8041 in /home/user, not in /, therefore clicking on "../" in the
8042 starting directory might send us to /home/).
8043 + When ftp login fails, (esp. when a user name was part of the
8044 URL already), we now return [401 Unauthorized ] to allow the
8045 browser to pop up an authorization dialog. This makes passwords
8046 slightly less visible (they don't appear in the regular log files)
8047 and implements a functionality that other www proxy servers
8051 *) Triggered by the recent "Via:" header changes, the proxy module would
8052 dump core for replies with invalid headers (e.g., duplicate
8053 "HTTP/1.0 200 OK" lines). These errors are now logged and the
8054 core dump is avoided. Also, broken replies are not cached.
8055 [Martin Kraemer] PR#2914
8057 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
8058 plop gmon.out profile data for each child [Doug MacEachern]
8060 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
8061 config.status script to be immune against arguments with whitespaces.
8062 [Yves Arrouye <yves apple.com>] PR#2866
8064 *) Replace the inlined information grabbing stuff for the configuration
8065 adjustment feature (no --without-confadjust) with calls to a new helper
8066 script `buildinfo.sh' which is both more flexible and already proofed to
8067 be more robust against platform differences. This mainly fixes the
8068 recently occured ``sed: command garbled: ...'' problems.
8069 [Ralf S. Engelschall] PR#2776, PR#2848
8071 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
8072 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
8073 without complains after we recently added the POST feature.
8074 [Ralf S. Engelschall]
8076 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
8077 modules as API functions and we forgot them at the big symbol renaming.
8078 [Ralf S. Engelschall]
8080 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
8081 [Youichirou Koga <y-koga jp.FreeBSD.ORG>] PR#2895
8083 *) Dynamically size the filename column of mod_autoindex output.
8086 *) Add the ability to do POST requests to the ab benchmarking tool.
8087 [Kurt Sussman <kls best.com>] PR#2871
8089 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
8090 5 to 10 because there are some users out there who always have 5 to 8
8091 variables in one RewriteRule and had to patch mod_rewrite.h for every
8092 release. So 15 should be now more than enough, even for them. (I never
8093 needed more than 4 in my RewriteRules ;-)
8094 [Ralf S. Engelschall]
8096 *) Make the proxy generate and understand Via: headers
8099 *) Change the proxy to use tables instead of array_headers for
8100 the header lines. [Martin Kraemer]
8102 *) Make sure the config.status file is not overridden when just
8103 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
8105 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
8106 provide a way to trace API changes that add functionality but do
8107 not create a compatibility issue for precompiled modules, etc.
8108 See include/ap_mmn.h for more details. [Randy Terbush]
8110 *) Fix suexec installation under `make install root=xxx' situation.
8111 [Ralf S. Engelschall]
8113 *) Extend the output of the -V switch to include the paths of all
8114 compiled-in configuration files, if they were overridden at
8115 compile time, for least astonishment of the user.
8118 *) When READing a request in ExtendedStatus mode, the "old"
8119 vhost, request and client information is not displayed.
8122 *) STATUS is no longer available. Full status information now
8123 run-time configurable using the ExtendedStatus directive.
8126 *) SECURITY [CAN-1999-1199] (cve.mitre.org):
8127 Eliminate O(n^2) space DoS attacks (and other O(n^2)
8128 cpu time attacks) in header parsing. Add ap_overlap_tables(),
8129 a function which can be used to perform bulk update operations
8130 on tables in a more efficient manner.
8133 *) SECURITY: Added compile-time and configurable limits for
8134 various aspects of reading a client request to avoid some simple
8135 denial of service attacks, including limits on maximum request-line
8136 size (LimitRequestLine), number of header fields (LimitRequestFields),
8137 and size of any one header field (LimitRequestFieldsize). Also added
8138 a configurable directive LimitRequestBody for limiting the size of the
8139 request message body. [Roy Fielding]
8141 *) Make status module aware of DNS and logging states, even if
8142 STATUS not defined. [Jim Jagielski]
8144 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
8146 *) Enhance mod_speling so that CheckSpelling can be used in
8147 <Directory> containers and .htaccess files. [Ken Coar]
8149 *) API: new ap_custom_response() function for hooking into the
8150 ErrorDocument mechanism at runtime [Doug MacEachern]
8152 *) API: new ap_uuencode() function [Doug MacEachern]
8154 *) API: scan_script_header_err_core() now "public" and renamed
8155 ap_scan_script_header_err_core() [Doug MacEachern]
8157 *) The 'status' module will now show the process pid's and their
8158 state even without full STATUS accounting. [Jim Jagielski]
8160 *) Restore the client IP address to the error log messages, this
8161 was lost during the transition from 1.2 to 1.3. Add a new
8162 function ap_log_rerror() which takes a request_rec * and
8163 formats it appropriately. [Dean Gaudet] PR#2661
8165 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
8166 whitespace in input lines -- including within quoted strings.
8168 but leading and trailing whitespace should continue to be
8169 stripped [Martin Kraemer]
8171 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
8172 the ugly use of an env. variable and use command-line args for
8173 alternate $PATH. Make more like advanced 'type's as well.
8176 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
8177 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
8178 <alain.st-denis ec.gc.ca>] PR#2736
8180 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
8182 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
8183 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
8184 directory was renamed to src/os/os2/ for consistency.
8185 [Brian Havard, Ralf S. Engelschall]
8187 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
8188 files (here modules) against other DSO files (here shared libraries).
8189 This is done by determining a subset of LIBS which can be safely used for
8190 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
8191 disabled for all platforms to avoid problems with this (experimental)
8192 rule. But we provide it now for those people how ran into problems and
8193 want to came out by forcing linking against DSOs.
8194 [Ralf S. Engelschall] PR#2587
8196 *) Fix suEXEC start message: Has to be of `notice' level to really get
8197 printed together with the standard startup message because the `notice'

8212 *) One more portability fix for APACI shadow tree support: Swap order of awk
8213 and sed in top-level configure script to avoid sed fails on some
8214 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the

8272 the read_request error conditions of URI-too-long (414) and
8273 malformed header fields (400). [Roy Fielding] PR#2646
8275 *) Add support for the Max-Forwards: header line required by RFC2068 for
8276 the TRACE method. This allows apache to TRACE along a chain of proxies
8277 up to a predetermined depth. [Martin Kraemer]
8279 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled
8280 (compilers complained) and the .so.V.R.P filename extension was adjusted

8319 *) Global renaming of C header files to both get rid of conflicts with third
8320 party packages and to again reach consistency:
8321 1. conf.h -> ap_config.h

8326 Backward compatibility files for conf.h and compat.h were created.
8328 *) mod_mmap_static will no longer take action on requests unless at
8329 least one "mmapfile" directive is present in the configuration.
8330 This experimental module has to do some black magic to operate
8331 inside the current API and thus creates side-effects for other

8445 *) WIN32: If we can't figure out how to execute a file in a script
8446 directory, bail out of the request with an error message. [W G Stoddard]
8448 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
8449 these are treated by Win32 as if they are ".." but are not detected by
8450 other machinery within Apache. This is something of a kludge but
8451 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
8453 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
8454 pools and thus pollutes libap (until the pool stuff is moved there).

8468 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
8469 remove some of the classical hurdles for new users when setting up
8470 Apache. This is done per default because it is useful for the average
8471 user. Package authors can use the --without-confadjust option to disable
8472 these configuration adjustments.
8473 [Ralf S. Engelschall]

8476 to add an extra Makefile dependency for the httpd target, for instance
8477 to external third-party libraries, etc.

8481 as <IfModule>..</IfModule> sections) which can be used to skip or process
8482 contained commands dependend of ``-D PARAMETER'' options on the command
8483 line. This can be used to achieve logical conditions like <IfDefine
8484 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
8485 and thus especially can be used for conditionally loading DSO-based
8486 modules via LoadModule, etc. [Ralf S. Engelschall]

8493 truncated which forced following HTTP headers to be data in the HTTP

8497 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
8498 in top-level configure script to avoid sed fails on some platforms (for
8499 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
8500 output of Awk. [Bill Houle <bhoule sandiegoca.ncr.com>] PR#2435
8502 *) Improve performance of directory listings (mod_autoindex) by comparing
8503 integer keys (last-modified and size) as integers rather than converting
8504 them to strings first. Also use a set of explicit byte tests rather
8505 than strcmp() to check for parent directory-ness of an entry. Oh, and
8506 make sure the parent directory (if displayed) is *always* listed first
8507 regardless of the sort key. Overall performance winnage should be good
8508 in CPU time, instruction cache, and memory usage, particularly for large
8509 directories. [Ken Coar]
8511 *) Add a tiny but useful goody to APACI's configure script: The generation
8512 of a config.status script (as GNU Autoconf does) which remembers the used
8513 configure command and hence can be used to restore the configuration by
8514 just re-running this script or for remembering the configuration between
8516 [Ralf S. Engelschall]
8518 *) Add httpd -t (test) option for running configuration syntax tests only.
8519 If something is broken it complains and exits with a return code
8520 non-equal to 0. This can be used manually by the user to check the Apache
8521 configuration after editing and is also automatically used by apachectl
8522 on (graceful) restart command to make sure Apache doesn't die on restarts
8523 because of a configuration which is now broken since the last (re)start.
8524 This way `apachectl restart' can be used inside cronjobs without having
8525 to expect Apache to be falling down. Additionally the httpd -t can be run
8526 via `apachectl configtest'.

8676 generated Makefile more user friendly. [Ralf S. Engelschall]
8678 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
8679 was updated to use the normal apache error processing, thereby allowing
8680 proxy errors to be treated by ErrorDocument's as well. For this
8681 purpose, a new module-to-core communication variable "error-notes"
8682 was introduced; the proxy (and possibly other modules) communicates
8683 its error text using this variable. Its content is copied to a new
8684 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
8685 The old proxy special error routine ap_proxy_log_uerror()

8695 ("make") of Apache we can allow, of course. Root privileges are needed

8770 variable is not the truth. Instead a special variable named LD_SHLIB is
8771 reasonable because although "ld" is usually the default, the command for
8772 building DSO files can be "libtool" or even "cc" on some systems.
8773 [Ralf S. Engelschall]
8775 *) Replace the AddVersionPlatform directive with ServerTokens which
8776 provides for more control over the format of the Server:
8777 header line. SERVER_SUBVERSION is no longer supported;
8778 all module should use the ap_add_version_component()
8779 API function instead. [Jim Jagielski]
8781 *) Support for the NCR MP/RAS 3.0
8782 [John Withers <withers semi.kcsc.mwr.irs.gov>]
8784 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
8785 not retrieved in src/Configure and thus was not useable.
8786 [Ralf S. Engelschall]
8788 *) Various Makefile consistency cleanups:
8789 - make OSDIR also automatically be relative to src/ like INCDIR
8790 - SUBDIRS is now generated in src/Makefile only and not in
8791 Makefile.config because it is a local define for this location.
8792 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
8793 any Makefile but make sure that at least the "-K inline" is kept in
8795 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
8796 - updated the dependencies theirself
8797 - removed not existing SHLIB variable from "clean" targets
8798 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
8799 already exists and OBJS_PIC are also just plain objects and have not
8800 directly to do with "shared" things. The only difference is that they
8801 contain PIC. So OBJS_PIC is the more canonical name.
8802 - Updated the Makefile-dependency lines for OBJS_PIC
8803 - Removed the Makefile-dependency line in Configure to avoid double
8805 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
8806 of xxx.lo as GNU libtool does with its PIC objects
8807 - reduce local complexity in modules Makefile.tmpl by moving the last
8808 existing target "depend" to the generation section in Configure, too.
8809 - removed the historical $(SPACER) which was used in the past together
8810 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
8811 is no longer needed.
8812 - force the build and run of the gen_xxx programs under main/ as the
8813 first step before building the objects because it looks cleaner
8814 [Ralf S. Engelschall]
8816 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
8819 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
8822 *) WIN32: Don't force ISAPI headers to finish with \n.
8823 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
8825 *) When opening "configuration" files (like httpd.conf, htaccess
8826 and htpasswd), Apache will not allow them to be non-/dev/null
8827 device files. This closes a DoS hole. At the same time,
8828 we use ap_pfopen to open these files to handle timeouts.
8829 [Jim Jagielski, Martin Kraemer]
8831 *) Apache will now log the reason its httpd children exit if they exit
8832 due to an unexpected signal. (It requires a new porting define,
8833 SYS_SIGLIST, which if defined should point to a list of text
8834 descriptions of the signals available. See PORTING.) [Dean Gaudet]
8836 *) WIN32: chdir() doesn't make sense in a multithreaded environment
8837 like WIN32. Before, Win32 CGI's could have had sporadic failures
8838 if a chdir call from one thread was made between another chdir call
8839 and a spawn in another thread. So, for now don't chdir for CGI scripts
8840 in WIN32. The current CGI "spec" is unclear as to whether it's
8841 necessary. Long-term fix is to either serialize the chdir/spawn combo
8842 or use WIN32 native calls to spawn a process. This temp fix was
8843 necessary to remove this as a showstopper for 1.3's release.
8846 *) Cleanup the suEXEC support in APACI and make it more safe:
8847 1. Add big fat hint in INSTALL about risks and to read the
8848 htdocs/manual/suexec.html document before using the suexec-related
8850 2. Make sure the user has at least provided one --suexec-xxxx option
8851 (specifies suEXEC parameters) in addition to --enable-suexec option.
8852 If only --enable-suexec is given APACI stops with a hint to INSTALL
8853 and htdocs/manual/suexec.html documents.
8854 3. Provide two additional --suexec-xxxx options to make the suEXEC
8855 configuration complete (especially for package maintainers who else
8856 had to patch the source tree) by providing ways to configure minimal
8857 UID/GID and safe PATH, too.
8858 [Ralf S. Engelschall]
8860 *) Cleanup of the `configure --shadow' process:
8861 - make sure the configure script creates its temporary files in the
8862 shadow tree to avoid conflicts with parallel configure runs
8863 - removed unnecessary option "-r" from "rm" call for Makefiles
8864 - make sure the configure scripts creates the shadow-wrapper Makefile
8865 only when no shadow trees already exists
8866 - make sure "make distclean" removes the shadow-wrapper Makefile but only
8867 when no more shadow trees exists
8868 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
8869 as fast (in the past it needed 70sec, now it runs just 38sec)
8870 - make sure CVS does not complain about the created files
8871 Makefille.<gnutriple> and directories src.<gnutriple>
8872 [Ralf S. Engelschall]
8874 *) Added the ap_add_version_component() API routine and the
8875 AddVersionPlatform core directive. The first allows modules to
8876 declare themselves in the Server response header field value,
8877 augmenting the SERVER_SUBVERSION define in the Configuration file
8878 with run-time settings (more useful in a loadable-module environment).
8879 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
8880 into the server version string. [Ken Coar] PR#2056
8882 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
8885 *) Emit the "Accept-Range" header for the default handler.
8886 [Brian Behlendorf] PR#1464
8888 *) Add a note to httpd.conf-dist that apache will on some systems fail
8889 to start when the Group # is set to a negative or large positive value.
8892 *) Make sure the module execution order is correct even when some modules
8893 are loaded under runtime (`LoadModule') via the DSO mechanism:
8894 1. The list of loaded modules is now a dynamically allocated one
8895 and not the original statically list from modules.c
8896 2. The loaded modules are now correctly setup by LoadModule for
8897 later use by the AddModule command.
8898 3. When the DSO mechanism for modules is used APACI's `install'
8899 target now enables all created `LoadModule' lines per default because
8900 this is both already expected by the user _and_ needed to avoid
8901 confusion with the next point and reduces the Makefile.tmpl complexity
8902 4. When the DSO mechanism for modules is used, APACI's `install'
8903 target now additionally makes sure the module list is reconstructed
8904 via a complete `ClearModuleList+AddModule...' entry.
8905 5. The support tool `apxs' now also makes sure an AddModule command
8906 is added in addition to the LoadModule command.
8907 6. The modules.c generation was extended to now contain two
8908 comments to make sure no one is confused by the confusing terminology
8909 of loading/linking (we use load=link+load & link=activate instead of
8910 the obvious load=activate & link=link :-( )
8911 This way now there is no longer a difference under execution time between
8912 statically and dynamically linked modules.
8913 [Ralf S. Engelschall]
8915 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
8916 Big Symbol Renaming. [Ralf S. Engelschall]
8918 *) Add a comment to mod_example.c showing the format of a FLAG command
8921 *) Standardized the time format in mod_status to match that of other
8922 places in the code (e.g. DATE_GMT). PR#1551
8924 *) Fix handling of %Z in timefmt strings for those platforms with no time
8925 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
8928 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
8929 feature compatible with 'UseCanonicalName off' by changing
8930 r->server->server_hostname to ap_get_server_name(). And I changed some
8931 functions which use r->server->port to use ap_get_server_port() instead,
8932 because if there's no Port directive in the config r->server->port is 0.
8935 *) get/set_module_config are trivial enough to be better off inline. Worth
8936 1.5% performance boost. [Dean Gaudet]
8938 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
8939 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
8942 *) [BS2000 security] BS2000 needs an extra authentication to initialize
8943 the task environment to the unprivileged User id. Otherwise CGI scripts
8944 would have a way to gain super user access. [Martin Kraemer]
8946 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
8947 absolute path, only log base name of logging source as is done
8948 in unix. [Martin Kraemer]
8950 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
8951 the encoding type from the Accept-Encoding header (if it's there)
8952 and use it in the response, as that's probably what it'll be expecting.
8953 [<Ronald.Tschalaer psi.ch>]
8955 *) Fix to mod_alias: translate_alias_redir is dealing with
8956 a URI, not a filename, so the check for drive letters for win32
8957 and emx is not necessary. [Dean Gaudet]
8959 *) WIN32: Allow .cmd as an executable extension.
8960 [Kari Likovuori <Kari.Likovuori mol.fi>] PR#2146
8962 *) Make Apache header files, and some variables, C++ friendly.
8963 [Michael Anderson's <mka redes.int.com.mx>]
8965 *) Child processes can now "signal" (by exiting with a status
8966 of APEXIT_CHILDFATAL) the parent process to abort and
8967 shutdown the server if the error in the child process was
8968 fatal enough. [Jim Jagielski]
8970 *) mod_autoindex's find_itme() was sensitive to MIME type case.
8971 [Jim Jagielski] PR#2112
8973 *) Make sure the referer_log and agent_log entries in the default httpd.conf
8974 file are also adjusted for the actual relative installation paths.
8975 [Ralf S. Engelschall] PR#2175
8977 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
8979 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
8982 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
8983 Additionally the checks for finding the vendor DSO library were moved
8984 from mod_so.c to Configure because first it needs $PLAT etc. and second
8985 mod_so already uses an abstraction layer and does not fiddle with the
8986 vendor functions itself.
8987 [Jens-Uwe Mager, Ralf S. Engelschall]
8989 *) PORT: Some optimization defines for NetBSD
8990 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
8992 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
8993 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
8995 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
8996 AIX variants should work fine, too. Even AIX 3.x should work). This is
8997 accomplished by using the free DSO emulation code from Jens-Uwe Mager
8998 which we put into a os/unix/os-dso-aix.c file.
8999 [Ralf S. Engelschall]
9001 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
9002 that we should use NET_SIZE_T == int but the include files force size_t.
9003 [Ralf S. Engelschall]
9005 *) Fix two bugs in select() handling in http_main.c.
9008 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
9009 is unset (as it is in situations like timeouts) where it is unclear
9010 whether errno is set or not. [Martin Kraemer]
9012 *) Just having APACI's localstatedir is too general and not enough for most
9013 of the systems. 1.3b6 again required manual APACI patches by package
9014 maintainers from Red Hat and FreeBSD because for their filesystem layout a
9015 little bit more flexibility in configuring the paths is needed. Hence we
9016 provide three additional configure options (--runtimedir, --logfiledir,
9017 --proxycachedir) which now can be used for more granular adjustments if
9018 --localstatedir is not enough to fit the particular needs. As a nice
9019 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
9020 [Ralf S. Engelschall]
9022 *) Make the install root for "make install" in APACI's Makefile overrideable
9023 by package authors. This way we are even more friendly to package
9024 maintainers (especially Debian and Red Hat) who build for the real prefix
9025 via "configure --prefix=/<real>" but use a different local prefix via
9026 "make root=/tmp/apache install" for rolling the package without bristling
9027 the target location on their system.
9028 [Ralf S. Engelschall]
9030 *) Workaround sed limitations in APACI's configure script by now
9031 substituting in chunks of 50 commands (because for instance HPUX's vendor
9032 sed has a limit of max. 98 commands)
9033 [Ralf S. Engelschall] PR#2136
9035 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
9036 [Ralf S. Engelschall] PR#2140
9038 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
9039 RENAMING process because they are defined as pre-processor macros instead
9040 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
9041 [Ralf S. Engelschall]
9043 *) Workaround braindead AWK's when generating ap_config.h: The split() and
9044 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
9045 [Ralf S. Engelschall] PR#2139
9047 *) Various bugfixes and cleanups for the APACI configure script:
9048 o fix IFS handling for _nested_ situation
9049 o fix Perl interpreter search: take first one found instead of last one
9050 o fix DSO consistency check
9051 o print error messages to stderr instead of stdout
9052 o add install-quiet for --shadow situation to Makefile stub
9053 o reduce complexity by avoiding sed-hacks for rule and module list loops
9054 [Ralf S. Engelschall]
9056 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
9058 *) Make sure the input field separator (IFS) shell variable is explicitly
9059 initialized correctly before _every_ `for' loop and also restored after
9060 the loops. [Ralf S. Engelschall]
9062 *) Make sure that "make install" doesn't overwrite the `mime.types' and
9063 `magic' files from an existing Apache installation. Because people often
9064 customize these for own MIME and content types.
9065 [Ralf S. Engelschall]
9067 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
9068 [Peter Galbavy, Ralf S. Engelschall] PR#2109
9070 *) Fix the path to the ScoreBoardFile in the install-config target, too.
9071 [Ralf S. Engelschall] PR#2105
9073 *) Let "configure" clear out the users parameters (provided as shell
9074 variables) to avoid side-effects in "src/Configure" when the user
9075 exported them (which is not needed, but some users do it).
9076 [Ralf S. Engelschall] PR#2101
9078 *) Provide backward compatibility from some old src/Configuration.tmpl
9079 parameter names to the canonical Autoconf-style shell variable names. For
9080 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
9081 but a hint message is displayed. [Ralf S. Engelschall]

9084 CGI scripts from an existing Apache installation.
9085 [Ralf S. Engelschall, Jim Jagielski] PR#2084
9087 *) Make `configure --compat' more "compatible" by first
9088 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
9089 second by making sure the "avoid-bristling-suffix" /apache is not
9090 appended to sysconfdir, datadir, localstatedir and includedir when
9091 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]

9099 *) Fix the path to the MimeMagicFile in the install-config target, too.
9100 [Ralf S. Engelschall] PR#2089
9102 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
9104 *) If you start apache with the -S command line option it will dump
9105 out the parsed vhost settings. This is useful for folks trying
9106 to figure out what is wrong with their vhost configuration.
9107 (Other dumps may be added in the future.) [Dean Gaudet]
9109 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
9110 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
9113 *) Because /usr/local/apache is the default prefix the ``configure
9114 --compat'' option no longer has to set prefix, again. This way the
9115 --compat option honors a leading --prefix option. [Lars Eilebrecht]
9117 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
9118 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
9119 to avoid "discard const" warnings. [Ralf S. Engelschall]
9121 *) If a specific handler is set for a file yet the request still
9122 ends up being handled by the default handler, log an error
9123 message before handling it. This catches things such as trying
9124 to use SSIs without mod_include enabled. [Marc Slemko]
9126 *) Fix error logging for the startup case where ap_log_error() still uses
9127 stderr as the target. Now the default log level is honored here, too.
9128 [Ralf S. Engelschall]
9130 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
9131 long" errors when generating the MODULES entry for src/Makefile
9132 [Ben Hyde, Ralf S. Engelschall]
9134 *) Make sure src/Configure doesn't complain about the old directory
9135 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
9137 Changes with Apache 1.3b6
9139 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
9141 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
9142 interface via the similar but proprietary HP/UX shl_xxx-style system
9143 calls. [Ralf S. Engelschall]
9145 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
9146 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
9147 Make. [Ralf S. Engelschall]
9149 *) ++++ THE BIG SYMBOL RENAMING ++++
9150 To avoid symbol clashes with third-party code compiled into the server,
9151 we globally applied the prefix "ap_" to the following classes of
9153 - Apache provided general functions (e.g., ap_cpystrn)
9154 - Public API functions (e.g., palloc, bgets)
9155 - Private functions which we can't make static (because of
9156 cross-object usage) but should be (e.g., new_connection)
9157 For backward source compatibility a new header file named compat.h was
9158 created which provides defines for the old symbol names and can be used
9159 by third-party module authors.
9162 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
9163 problem under SVR4 is that there is no command flag to force the linker
9164 to export the global symbols of the httpd executable therewith they are
9165 available to the DSO's. Instead of problematic hacks like creating a
9166 dummy.so file (containing dummy references to all global symbols) the
9167 httpd binary is linked against, we use a clean trick stolen from Perl 5:
9168 Placing the Apache core code itself into a DSO library named libhttpd.so.
9169 This way the global symbols _HAVE_ to be exported and thus are available
9170 to any manually loaded DSO's under runtime. To reduce the impact to the
9171 user to null we go even further and create a stub httpd executable which
9172 automatically keeps track of the DSO library loading itself and thus
9173 hides the complete mechanism from the user. Although the generation of
9174 this DSO library is automatically triggered for platforms which
9175 essentially need it (mostly all SVR4-derivates) it can be also enabled
9176 manually via the Rule SHARED_CORE. This can be interesting in the future
9177 where we perhaps exploit this libhttpd.so mechanism for providing nifty
9178 features like graceful upgrades, or whatever.
9179 [Ralf S. Engelschall, Martin Kraemer]
9181 *) Build the libraries before building the rest of the tools. [Ben Hyde]
9183 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
9184 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
9185 conventions while "clean" removes only stuff created by "all" targets,
9186 "distclean" additionally removes the stuff from the configuration
9187 process. This way "make distclean" (hence the name) provides a fresh
9188 source tree as it was for distribution.
9189 [Ralf S. Engelschall]
9191 *) Allow top-level (APACI) Makefile to break on build errors
9192 the same way the src/ subtree Makefiles breaks on them by replacing the
9193 initial APACI sed-subdir-display-kludge with a more clean
9194 variable-passing-solution: variable SDP can optionally hold the subdir
9195 prefix which is consistently used for displaying the subdir movement.
9196 This way even the top-level Makefile can stop correctly on errors as the
9197 user expects. [Ralf S. Engelschall]
9199 *) Fixed ordering of argument checks for RewriteBase directive.
9200 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
9202 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
9203 indicating that a module is being compiled for dynamic loading. Also
9204 remove #define IS_MODULE from modules and add SHARED_MODULE define
9205 to the mak/dsp files. [Alexei Kosut]
9207 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
9208 since we are now logging APLOG_WARNING by default. [Roy Fielding]
9210 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
9212 *) Add documentation file and src/Configuration.tmpl entry for the
9213 experimental mod_mmap_static module. Because although it is and marked as
9214 an experimental one it is distributed and thus should be documented and
9215 prepared for configuration the same way as all others modules.
9216 [Ralf S. Engelschall]
9218 *) Add query (-q) option to apxs support tool to be able to manually query
9219 specific settings from apxs. This is needed for instance when you
9220 manually want to access Apache's header files and you need to assemble
9221 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
9222 [Ralf S. Engelschall]
9224 *) Now src/Configure uses a fallback strategy for the shared object support
9225 on platforms where no explicit information is available: If a Perl
9226 installation exists we ask it about its shared object support and if it's
9227 the dlopen-style one we shamelessly guess the compiler and linker flags
9228 for creating shared objects from Perls knowledge. Of course, the user is
9229 warning about what we are doing and informed that he should send us
9230 the guessed flags when they work. [Ralf S. Engelschall]
9232 *) Provide APACI --without-support option to be able to disable the build
9233 and installation of the support tools from the src/support/ area.
9234 Although its useful to have these installed per default we should provide
9235 a way to compile and install without them for backward-compatibility.
9236 [Ralf S. Engelschall]
9238 *) Add of the new APache eXtenSion (apxs) support tool for building and
9239 installing modules into an _already installed_ Apache package through the
9240 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
9241 this approach actually doesn't need the Apache source tree. The
9242 (APACI-installed) server package is enough, because this now includes the
9243 Apache C header files (PREFIX/include) and the new APXS tool
9244 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
9245 module authors to build their Apache modules _OUTSIDE_ the Apache source
9246 tree while avoiding them to fiddle around with the totally platform
9247 dependend way of compiling DSO files. The tool supports all ranges of
9248 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
9249 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
9250 on-the-fly generate a minimalistic Makefile and sample module for the
9251 first step to provide both a quick success event and to demonstrate the
9252 APXS mechanism to module authors. [Ralf S. Engelschall]
9254 *) Fix core dumps in use of CONNECT in proxy.
9255 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
9257 *) Modify the log directives in httpd.conf-dist files to use CustomLog
9258 so that users have examples of how CustomLog can be used.
9261 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
9262 the Apache distribution tree. Until Apache 1.3 there was no real
9263 out-of-the-box batch-capable build and installation procedure for the
9264 complete Apache package. This is now provided by a top-level "configure"
9265 script and a corresponding top-level "Makefile.tmpl" file. The goal is
9266 to provide a GNU Autoconf-style frontend which is capable to both drive
9267 the old src/Configure stuff in batch and additionally installs the
9268 package with a GNU-conforming directory layout. Any options from the old
9269 configuration scheme are available plus a lot of new options for flexibly
9270 customizing Apache. [Ralf S. Engelschall]
9272 *) The floating point ap_snprintf code wasn't threadsafe.
9273 Had to remove the HAVE_CVT macro in order to do threadsafe
9274 calling of the ?cvt() floating point routines. [Dean Gaudet]
9276 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
9278 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler

9281 *) BUG: Configure was using TCC and CC inconsistently. Make sure
9282 Configure knows which CC we are using. [Jim Jagielski]
9284 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
9285 was defined in a parent directory. [Lars Eilebrecht]
9287 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
9288 a generic printf-style routine that can call arbitrary output
9289 routines. Use this to replace http_bprintf.c. Add new routines
9290 psprintf(), pvsprintf() which allocate the exact amount of memory
9291 required for a string from a pool. Use psprintf() to clean up
9292 various bits of code which used ap_snprintf()/pstrdup().
9295 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
9296 ap_snprintf() has different semantics and formatting codes than
9297 snprintf(). [Dean Gaudet]
9299 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
9300 is necessary on at least Solaris where the /etc/rc?.d scripts
9301 are run with these signals ignored, and "SIG_IGN" settings are
9302 maintained across exec().

9313 *) A few changes to scoreboard definitions which helps gcc generate
9314 better code. [Dean Gaudet]
9316 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
9317 be a signed bitfield. So mark a few bitfields as signed to

9320 *) The default for HostnameLookups was changed to Off, but there
9321 was a problem and it wasn't taking effect. [Dean Gaudet]
9323 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
9326 *) After a SIGHUP the listening sockets in the parent weren't
9327 properly marked for closure on fork().
9328 [Jürgen Keil <jk tools.de>] PR#2000
9330 *) Allow %2F in two situations: 1) it is in the query part of the URI,
9331 therefore not exposed to %2F -> '/' translations and 2) the request
9332 is a proxy request, so we're not dealing with a local resource anyway.
9333 Without this, the proxy would fail to work for any URL's with
9334 %2f in them (occurs quite often in
9335 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
9337 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
9339 *) Make the shared object compilation command more portable by avoiding
9340 the direct combination of `-c' & `-o' which is not honored by some
9341 compilers like UnixWare's cc. [Ralf S. Engelschall]
9343 *) WIN32: the proxy was creating filenames missing the last four
9344 characters. While this normally doesn't stop anything from
9345 working, it can result in extra collisions.
9346 [Tim Costello <tjcostel socs.uts.edu.au>] PR#1890
9348 *) Now mod_proxy uses the response string (in addition to the response status
9349 code) from the already used FTP SIZE command to setup the Content-Length
9350 header if available. [Ralf S. Engelschall] PR#1183
9352 *) Reanimated the (still undocumented) proxy receive buffer size directive:
9353 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
9354 name was really too generic, added documentation for this directive to
9355 the mod_proxy.html and corrected the hyperlink to it in the
9356 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
9358 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
9359 faster [Martin Kraemer]
9361 *) Make Configure die when you give it an unknown command switch.
9364 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
9365 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
9366 and per default compiled support programs have manual pages - just to
9367 document our stuff a little bit more and to be able to do really
9368 Unix-like installations ;-) [Ralf S. Engelschall]
9370 *) Major cleanups to the Configure script to make it and its generated
9371 Makefiles again readable and maintainable: add SRCDIR option, removed
9372 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
9373 generated sections, consequently added Makefile headers with inheritance
9374 information, added subdir movement messages for easier following where
9375 the build process currently stays (more verbose then standard Make, less
9376 verbose than GNU make), same style to comments in the Configure script,
9377 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
9379 *) Add the new ApacheBench program "ab" to src/support/: This is derived
9380 from the ZeusBench benchmarking program and can be used to determine the
9381 response performance of an Apache installation. This version is
9382 officially licensed with Zeus Technology, Ltd. See the license agreement
9383 statements in <199803171224.NAA24547 en1.engelschall.com> in apache-core.
9384 [Ralf S. Engelschall]
9386 *) API: Various core functions that are definately not part of the API
9387 have been made static, and a few have been marked API_EXPORT. Still
9388 more have been marked CORE_EXPORT and are not intended for general
9389 use by modules. [Doug MacEachern, Dean Gaudet]
9391 *) mod_proxy was not clearing the Proxy-Connection header from
9392 requests; now it does. This did not violate any spec, however
9393 causes poor interactions when you are talking to remote proxies.
9394 [Marc Slemko] PR#1741
9396 *) Various cleanups to the command line interface and manual pages.
9397 [Ralf S. Engelschall]
9399 *) cfg_getline() was not properly handling lines that did not end
9400 with a line termination character. [Marc Slemko] PR#1869, 1909
9402 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
9404 *) Clean up some undocumented behavior of mod_setenvif related to
9405 "merging" two SetEnvIf directives when they match the same header
9406 and regex. Document that mod_setenvif will perform comparisons in
9407 the order they appear in the config file. Optimize mod_setenvif by
9408 doing more work at config time rather than at runtime.
9411 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
9412 to allow for modules to overrule them and to reduce redefinition
9413 warnings [Jim Jagielski]
9415 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
9418 *) Making the hard-coded cross-module function call mime_find_ct() (from
9419 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
9420 checking is really called even for proxy requests except for URLs with
9421 HTTP schemes (because there we can optimize by not running the type
9422 checking hooks due to the fact that the proxy gets the MIME Content-type
9423 from the remote host later). This change cleans up mod_mime by removing
9424 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
9425 especially unbundles mod_proxy and mod_mime. This way they both now can
9426 be compiled as shared objects and are no longer tied together.
9427 [Ralf S. Engelschall]
9429 *) util.c cleanup and speedup. [Dean Gaudet]
9431 *) API: Clarification, pstrndup() will always copy n bytes of the source
9432 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
9434 *) Mark module command_rec and handler_rec structures const so that they
9435 end up in the read-only data section (and are friendlier to systems
9436 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
9438 *) Add check to the "Port" directive to make sure the specified
9439 port is in the appropriate range. [Ben Hyde]
9441 *) Performance improvements to invoke_handler().
9442 [Dmitry Khrustalev <dima bog.msu.su>]
9444 *) Added support for building shared objects even for library-style modules
9445 (which are built from more than one object file). This now provides the
9446 ability to build mod_proxy as a shared object module. Additionally
9447 modules like mod_example are now also supported for shared object
9448 building because the generated Makefiles now no longer assume there is at
9449 least one statically linked module. [Ralf S. Engelschall]
9451 *) API: Clarify usage of content_type, handler, content_encoding,
9452 content_language and content_languages fields in request_rec. They
9453 must always be lowercased; and the strings pointed to shouldn't
9454 be modified (you must copy them to modify them). Fix a few bugs
9455 related to this. [Dean Gaudet]
9457 *) API: Clarification: except for RAW_ARGS, all command handlers can
9458 treat the char * parameters as permanent, and modifiable. There
9459 is no need to pstrdup() them. Clean up some needless pstrdup().
9462 *) Now mod_so keeps track of which module shared objects with which names
9463 are loaded and thus avoids multiple loading and unloading and irritating
9464 error_log messages. [Ralf S. Engelschall]
9466 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
9467 environment variable in the apache core. But that tweaking interferes
9468 with mod_setenv. So don't tweak if the user has specified an explicit
9469 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888
9471 *) rputs() did not calculate r->sent_bodyct properly.
9472 [Siegmund Stirnweiss <siegst kat.ina.de>] PR#1900
9474 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
9475 name, or left unset if this value is unavailable. Apache was setting
9476 it to the IP address when unavailable.
9477 [Tony Finch <fanf demon.net>] PR#1925
9479 *) Various improvements to the configuration and build support for compiling
9480 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
9481 OSF1 support with GCC and vendor compilers was added. This way shared
9482 object support is now provided out-of-the-box for FreeBSD, Linux,
9483 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
9484 [Ralf S. Engelschall]
9486 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
9487 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
9488 and USE_OS2_SCOREBOARD. [Dean Gaudet]
9490 *) Fix one more special locking problem for RewriteMap programs in
9491 mod_rewrite: According to the documentation of flock(), "Locks are on
9492 files, not file descriptors. That is, file descriptors duplicated
9493 through dup(2) or fork(2) do not result in multiple instances of a lock,
9494 but rather multiple references to a single lock. If a process holding a
9495 lock on a file forks and the child explicitly unlocks the file, the
9496 parent will lose its lock.". To overcome this we have to make sure the
9497 RewriteLock file is opened _AFTER_ the childs were spawned which is now
9498 the case by opening it in the child_init instead of the module_init API
9499 hook. [Ralf S. Engelschall] PR#1029
9501 *) Change to Location and LocationMatch semantics. LocationMatch no
9502 longer lets a single slash match multiple adjacent slashes in the
9503 URL. This change is for consistency with RewriteRule and
9504 AliasMatch. Multiple slashes have meaning in URLs that they do
9505 not have in (some) filesystems. Location on the other hand can
9506 be considered a shorthand for a more complicated regex, and it
9507 does match multiple slashes with a single slash -- which is
9508 also consistent with the Alias directive.
9509 [Dean Gaudet] related PR#1440
9511 *) Fix bug with mod_mime_magic causing certain files, including files
9512 of length 0, to result in no response from the server.
9515 *) The Configure script now generates src/include/ap_config.h which
9516 contains the set of defines used when Apache is compiled on a platform.
9517 This file can then be included by external modules before including
9518 any Apache header files in case they are being built separately from
9519 Apache. Along with this change, a couple of minor changes were
9520 made to make Apache's #defines coexist peacefully with any autoconf
9521 defines an external module might have. [Rasmus Lerdorf]
9523 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9524 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9525 chance by the API to initialize its per-server configuration and thus
9526 receives the wrong one from the main server. This is now avoided by
9527 remembering the server together with the config structure while
9528 configuring and later assuming there is no config when we see a
9529 difference between the remembered server and the one calling us.
9530 [Ralf S. Engelschall] PR#1790
9532 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9533 is automatically disabled under configure time when the dbm_xxx functions
9534 are not available. Second, two heavy source code errors in the DBM
9535 support code were fixed. This makes DBM RewriteMap's usable again after
9536 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9538 *) Now all configuration files support Unix-style line-continuation via
9539 the trailing backslash ("\") character. This enables us to write down
9540 complex or just very long directives in a more readable way. The
9541 backslash character has to be really the last character before the
9542 newline and it has not been prefixed by another (escaping) backslash.

9548 *) To deal with modules being compiled and [dynamically] linked
9549 at a different time from the core, the SERVER_VERSION and
9550 SERVER_BUILT symbols have been abstracted through the new
9551 API routines apapi_get_server_version() and apapi_get_server_built().
9554 *) WIN32: Preserve trailing slash in canonical path (and hence
9555 in PATH_INFO). [Paul Sutton, Ben Laurie]
9557 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
9558 depending on the rev of Solaris and what mixture of modules
9559 are in use. So it has been disabled, and Solaris is back to
9560 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9561 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9562 up static content only servers. Or it may fail unpredictably.
9563 [Dean Gaudet] PR#1779, 1854, 1904
9565 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9568 *) API: Rewrite of absoluteURI handling, and in particular how
9569 absoluteURIs match vhosts. Unless a request is a proxy request, a
9570 "http://host" url is treated as if a similar "Host:" header had been
9571 supplied. This change was made to support future HTTP/1.x protocols
9572 which may require clients to send absoluteURIs for all requests.
9574 In order to achieve this change subtle changes were made to the API. In a
9575 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9576 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9577 by the core, modules must set it during the post_read_request or
9578 translate_names phase.
9580 Plus changes to the virtualhost test suite for absoluteURI testing.
9582 This fixes several bugs with the proxy proxying requests to vhosts
9583 managed by the same httpd.
9586 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
9587 code from mod_rewrite. The vhost matching is now performed by a
9588 globally available function matches_request_vhost(). [Dean Gaudet]

9604 *) API: A new source module main/util_uri.c; It contains a routine
9605 parse_uri_components() and friends which breaks a URI into its component
9606 parts. These parts are stored in a uri_components structure called
9607 parsed_uri within each request_rec, and are available to all modules.
9608 Additionally, an unparse routine is supplied which re-assembles the URI
9609 components back to an URI, optionally hiding the username:password@ part
9610 from ftp proxy requests, and other useful routines. Within the structure,
9611 you find on a ready-for-use basis:
9612 scheme; /* scheme ("http"/"ftp"/...) */
9613 hostinfo; /* combined [user[:password]@]host[:port] */
9614 user; /* user name, as in http://user:passwd@host:port/ */
9615 password; /* password, as in http://user:passwd@host:port/ */
9616 hostname; /* hostname from URI (or from Host: header) */
9617 port_str; /* port string (integer representation is in "port") */
9618 path; /* the request path (or "/" if only scheme://host was given) */
9619 query; /* Everything after a '?' in the path, if present */
9620 fragment; /* Trailing "#fragment" string, if present */
9621 This is meant to serve as the platform for *BIG* savings in
9622 code complexity for the proxy module (and maybe the vhost logic).
9625 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
9626 ${map:key}) available for all location where a string is created in
9627 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
9628 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
9629 possible expansions are consequently usable at all string creation
9630 locations. [Ralf S. Engelschall]
9632 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
9633 and not 1) and the per-virtual-server merging of directives. Now all

9635 completely overridden (default) or completely inherited (when
9636 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

9645 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
9646 (like SunOS and FreeBSD) which don't accept the locking of pipes

9666 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
9667 type but with a special post-processing for the looked-up value: It
9668 parses it into alternatives according to `|' chars and then only one
9669 particular alternative is chosen randomly (this is an essential
9670 functionality needed for balancing between backend-servers when using
9671 Apache as a Reverse Proxy. The looked up value here is a list of
9672 servers). Second, `int' with the built-in maps named `tolower' and
9673 `toupper' which can be used to map URL parts to a fixed case (this is an
9674 essential feature to fix the case of server names when doing mass
9675 virtual-hosting with the help of mod_rewrite instead of using
9676 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
9677 Jay Soffian <jay cimedia.com>] PR#1631
9679 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
9680 This directive lets Apache adjust the URL in Location-headers on HTTP
9681 redirect responses sent by the remote server. This way the virtually
9682 mapped area is no longer left on redirects and thus by-passed which is
9683 especially essential when running Apache as a reverse proxy.

9734 similary for Location and Directory), now this is diagnosed as an
9735 error. Improve error messages for mismatched sections (<Files>,
9736 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).
9737 [Dean Gaudet, Martin Kraemer]
9739 *) <Files> is not permitted within <Location> (because of the
9740 semantic ordering). [Dean Gaudet] PR#379
9742 *) <Files> with wildcards was broken by the change in wildcard
9743 semantics (* does not match /). To fix this, <Files> now
9744 apply only to the basename of the request filename. This
9745 fixes some other inconsistencies in <Files> semantics

9753 *) Various errors from select() and accept() in child_main() would
9754 result in an infinite loop. It seems these two tickle kernel
9755 or library bugs occasionally, and result in log spammage and
9756 a generally bad scene. Now the child exits immediately,
9757 which seems to be a good workaround.

9771 Changes with Apache 1.3b5
9773 *) Source file dependencies in Makefile.tmpl files throughout the

9784 Changes with Apache 1.3b4
9786 *) The module structure was modified to include a *dynamic_load_handle
9787 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
9788 has been bumped accordingly. [Paul Sutton]
9790 *) All BrowserMatch directives mentioned in
9791 htdocs/manual/known_client_problems.html are in the default
9792 configuration files. [Lars Eilebrecht]
9794 *) MiNT port update. [Jan Paul Schmidt]
9796 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
9797 equivalent, similarly for x-compress and compress. Apache
9798 now ignores a leading x- when comparing encodings. It also
9799 preserves the encoding the client requests (for example if
9800 it requests x-gzip, then Apache will respond with x-gzip
9801 in the Content-Encoding header).
9802 [Ronald Tschalaer <Ronald.Tschalaer psi.ch>] PR#1772
9804 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
9806 *) Added mod_so module to support dynamic loading of modules on Unix
9807 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
9808 instead of AddModule in Configuration to build shared modules

9811 *) Minor cleanups to r->finfo handling in some modules.
9814 *) Abstract read()/write() to ap_read()/ap_write().
9815 Makes it easier to add other types of IO code such as SFIO.
9818 *) API: Generalize default_port manipulations to make support of
9819 different protocols easier. [Ben Laurie, Randy Terbush]
9821 *) There are many cases where users do not want Apache to form
9822 self-referential urls using the "canonical" ServerName and Port.
9823 The new UseCanonicalName directive (default on), if set to off
9824 will cause Apache to use the client-supplied hostname and port.

9829 PR#315, 459, 485, 1433
9831 *) Yet another rearrangement of the source tree.. now all the common
9832 header files are in the src/include directory. The -Imain -Iap
9833 references in Makefiles have been changed to the simpler -Iinclude
9834 instead. In addition to simplifying the build a little bit, this
9835 also makes it clear when a module is referencing something in a
9836 other than kosher manner (e.g., the proxy including mod_mime.h).
9837 Module-private header files (the proxy, mod_mime, the regex library,
9838 and mod_rewrite) have not been moved to src/include; nor have
9839 the OS-abstraction files. [Ken Coar]
9841 *) Fix a bug where r->hostname didn't have the :port stripped
9842 from it. [Dean Gaudet]
9844 *) Tweaked the headers_out table size, and the subprocess_env
9845 table size guess in rename_original_environment(). Added
9846 MAKE_TABLE_PROFILE which can help discover make_table()
9847 calls that use too small an initial guess, see alloc.c.
9850 *) Options and AllowOverride weren't properly merging in the main
9851 server setting inside vhosts (only an issue when you have no
9852 <Directory> or other section containing an Options that affects
9853 a request). Options +foo or -foo in the main_server wouldn't
9854 affect the main_server's lookup defaults. [Dean Gaudet]
9856 *) Variable 'cwd' was being used pointlessly before being set.
9859 *) r->allowed handling cleaned up in the standard modules.
9862 *) Some case-sensitivity issues cleaned up to be consistent with
9863 RFC2068. [Dean Gaudet]
9865 *) SIGURG doesn't exist everywhere.
9866 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
9868 *) mod_unique_id was erroneously generating a second unique id when
9869 an internal redirect occured. Such redirects occur, for example,
9870 when processing a DirectoryIndex match. [Dean Gaudet]
9872 *) API: table_add, table_merge, and table_set include implicit pstrdup()
9873 of the key and value. But in many cases this is not required
9874 because the key/value is a constant, or the value has been built
9875 by pstrcat() or other similar means. New routines table_addn,
9876 table_mergen, and table_setn have been added to the API, these
9877 routines do not pstrdup() their arguments. The core code and
9878 standard modules were changed to take advantage of these routines.
9879 The resulting server is up to 20% faster in some situations.
9881 Note that it is easy to get code subtly wrong if you pass a key/value
9882 which is in a pool other than the pool of the table. The only
9883 safe thing to do is to pass key/values which are in the pool of
9884 the table, or in one of the ancestors of the pool of the table.
9885 i.e. if the table is part of a subrequest, a value from the main
9886 request's pool is OK since the subrequest pool is a sub_pool of the
9887 main request's pool (and therefore has a lifespan at most as long as
9888 the main pool). There is debugging code which can detect improper
9889 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
9890 [Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet]
9892 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
9893 which don't exist on disk more gracefully; handles vhosts properly.
9894 Update documentation to reflect the code -- if there's no
9895 MimeMagicFile directive then the module is not enabled.
9898 *) PORT: Some older *nix dialects cannot automatically start scripts
9899 which begin with a #! interpreter line (the shell starts the scripts
9900 appropriately on these platforms). Apache now supports starting of
9901 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
9902 [Martin Kraemer, with code from Peter Wemm <peter zeus.dialix.oz.au>
9905 *) API: "typedef array_header table" removed from alloc.h, folks should
9906 have been writing to use table as if it were an opaque type, but even
9907 some standard modules got this wrong. By changing the definition
9908 to "typedef struct table table" module authors will receive compile
9909 time warnings that they're doing the wrong thing. This change
9910 facilitates future changes with more sophisticated table
9911 structures. Specifically, module authors should be using table_elts()
9912 to get access to an array_header * for the table. [Dean Gaudet]
9914 *) API: Renamed new_connection() to avoid namespace collision with LDAP
9915 library routines. [Ken Coar, Rasmus Lerdorf]
9917 *) WIN32: mod_speling is now available on the Win32 platform.
9920 *) For clarity the following compile time definition was changed:
9922 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
9924 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
9925 and not be a general notice that the OS has mmap(). Now the
9926 HAVE_MMAP/SHMGET #defines strictly are informational that the
9927 OS has that method of shared memory; the type to use for
9928 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
9929 and USE_SHMGET_SCOREBOARD). This allows outside modules to
9930 determine if shared memory is available and allows Apache
9931 to determine the best method to use for the scoreboard.
9934 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
9935 as do various earlier versions. It should be safe on all versions.
9936 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
9937 the slack code. A few other cleanups for Unixware.

9945 as a POST problem with MSIE 4.0, typically against pages which are
9946 authenticated. [Roy Fielding] PR#1399
9948 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization

9959 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
9960 The choice of flock vs. fcntl was made based on timings which showed that
9961 even on non-NFS, non-exported filesystems fcntl() was an order of
9962 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
9963 that single socket users will see no difference. [Dean Gaudet] PR#467

9985 *) Some const declarations in mod_imap.c that were added for debugging
9986 purposes caused some compilers heartburn without adding any
9987 significant value, so they've been removed. [Ken Coar]
9989 *) The src/main/*.h header files have had #ifndef wrappers added to
9990 insulate them against duplicate calls if they get included through
9991 multiple paths (e.g., in .c files as well as other .h files).
9994 *) The libap routines now have a header file for their prototypes,
9995 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
9997 *) mod_autoindex with a plaintext header file would emit the <PRE>
9998 start-tag before the HTML preamble, rather than after the preamble
9999 but before the header file contents. [John Van Essen <jve gamers.org>]
10002 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
10003 only an issue on systems without a MAXDNAME define or where
10004 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
10006 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
10007 is used to read various types of files such as htaccess and
10008 htpasswd files. [Marc Slemko]
10010 *) SECURITY: Ensure that the buffer returned by ht_time is always
10011 properly null terminated. [Marc Slemko]
10013 *) The "Connection" header could be sent back with multiple "close"
10014 tokens. Not an error, but a waste.
10015 [<Ronald.Tschalaer psi.ch>] PR#1683
10017 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
10018 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
10020 *) "basic" auth needs a case-insensitive comparison.
10021 [<Ronald.Tschalaer psi.ch>] PR#1666
10023 *) For maximum portability, the environment passed to CGIs should
10024 only contain variables whose names match the regex
10025 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
10026 underscores over any character outside the regex. This
10027 affects HTTP_* variables, in a way that should be backward
10028 compatible for all the standard headers; and affects variables
10029 set with SetEnv/BrowserMatch and similar directives.
10032 *) mod_speling returned incorrect HREF's when an ambigous match

10068 *) SECURITY: Numerous changes to mod_imap in a general cleanup
10069 including fixing a possible buffer overflow. [Dean Gaudet]
10071 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful

10073 (but there is as yet no way to signal this to Apache). Various
10074 other cleanups. [Paul Sutton]
10076 *) The aplog_error changes specific to 1.3 introduced a buffer
10077 overrun in the (now legacy) log_printf function. Fixed.
10080 *) mod_digest didn't properly deal with proxy authentication. It
10081 also lacked a case-insensitive comparision of the "Digest"
10082 token. [Ronald Tschalaer <Ronald.Tschalaer psi.ch>] PR#1599
10084 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
10086 *) A few cleanups in mod_info to make it thread-safe, and remove an

10093 ap_cpystrn() for performance and functionality reasons.

10111 alloc.c (affects win32 only). [Ben Hyde]
10113 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
10115 *) send_fd_length() did not calculate total_bytes_sent properly.
10116 [Ben Reser <breser regnow.com>] PR#1366
10118 *) The bputc() macro was not properly integrated with the chunking
10119 code; in many cases modules using bputc() could cause completely
10120 bogus chunked output. (Typically this will show up as problems
10121 with Internet Explorer 4.0 reading a page, but other browsers
10122 having no problem.) [Dean Gaudet]
10124 *) Create LARGE_WRITE_THRESHOLD define which determines how many
10125 bytes have to be supplied to bwrite() before it will consider
10126 doing a writev() to assemble multiple buffers in one system
10127 call. This is critical for modules such as mod_include,
10128 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
10129 strings in some cases. The result would be extra effort
10130 setting up writev(), and in many cases extra effort building
10131 chunks. The default is 31, it can be overriden at compile
10132 time. [Dean Gaudet]
10134 *) Move the gid switching code into the child so that log files

10253 which are allocated in each child, for cleanup in each child.
10254 A new pool was created which is passed to the module child_init
10255 and child_exit functions; modules are free to register per-child
10256 cleanups there. This fixes a bug with reliable piped logs.
10259 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
10260 unless it was also doing FancyIndexes, but it displayed the
10261 HeaderName file at the top under all circumstances. It now shows
10262 the ReadmeName file for simple indices, too, as it should.
10265 *) http_core was mmap()ing even in cases where it wasn't going to
10266 read the file. [Ben Hyde <bhyde gensym.com>]
10268 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
10269 Now the rewriting engine (the heart of mod_rewrite) is organized more
10270 straight-forward, first time well documented and reduced to the really
10271 essential parts. All redundant cases were stripped off and processing now
10272 is the same for both per-server and per-directory context with only a
10273 minimum difference (the prefix stripping in per-dir context). As a
10274 side-effect some subtle restrictions and two recently discovered problems
10275 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
10276 context and restrictions on the substitution URL on redirects.
10277 Additionally some minor source cleanups were done.

10284 *) If ap_slack fails to allocate above the low slack line it's a good

10432 Changes with Apache 1.3b2 (there is no 1.3b1)
10434 *) TestCompile was not passing $LIBS [Dean Gaudet]
10436 *) Makefile.tmpl was not using $CFLAGS in the link phase.
10439 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
10440 rudimentary memory debugger which can be used on live servers with
10441 low impact -- it sets all allocated and freed memory bytes to 0xa5.
10442 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
10443 and free() for each object. This is far more expensive and should
10444 only be used for testing with tools such as Electric Fence and
10445 Purify. See main/alloc.c for more details. [Dean Gaudet]
10447 *) Configure uses a sh trap and didn't set its exitcode properly.
10448 [Dean Gaudet] PR#1159
10450 *) Yet another vhost revamp. Add the NameVirtualHost directive which
10451 explicitly lists the ip:port pairs that are to be used for name-vhosts.
10452 From a given ip:port, regardless what the Host: header is, you can
10453 only reach the vhosts defined on that ip:port. The precedence of
10454 vhosts was reversed to match other precedences in the config --
10455 the earlier vhosts override the later vhosts. All vhost matching was
10456 moved into http_vhost.[ch]. [Dean Gaudet]
10458 *) ap_inline can be used to force inlining. GNUC __attribute__() can
10459 be used for whatever reason is appropriate (i.e. format() warnings
10460 for printf style functions). Both are enabled only with
10461 gcc >= 2.7.x (so that we have fewer support issues with older
10462 versions). [Dean Gaudet]
10464 *) Fix support for Proxy Authentication (we were testing the response
10465 status too early). [Marc Slemko]
10467 *) CoreDumpDirectory directive directs where the core file is
10468 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
10469 received. [Marc Slemko, Dean Gaudet]
10471 *) PORT: Support for Atari MINT.
10472 [Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
10474 *) When booting, apache will now detach itself from stdin, stdout,
10475 and stderr. stderr will not be detached until after the config
10476 files have been read so you will be able to see initial error
10477 messages. After that all errors are logged in the error_log.
10478 This makes it more convenient to start apache via rsh, ssh,
10479 or crontabs. [Dean Gaudet] PR#523
10481 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10482 Also removed the auto-generated link to www.apache.org that was the
10483 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10485 *) send_fb would not detect aborted connections in some situations.
10488 *) mod_include would use uninitialized data when parsing certain
10489 expressions involving && and ||. [Brian Slesinsky] PR#1139
10491 *) mod_imap should only handle GET methods. [Jay Bloodworth]
10493 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10495 *) mod_autoindex improperly counted &escapes; as more than one
10496 character in the description. It also improperly truncated
10497 descriptions that were exactly the maximum length.
10500 *) RedirectMatch was not properly escaping the result (PR#1155). Also
10501 "RedirectMatch /advertiser/(.*) $1" is now permitted.
10504 *) mod_include now uses symbolic names to check for request success
10505 and return HTTP errors, and correctly handles all types of
10506 redirections (previously it only did temporary redirect correctly).
10507 [Ken Coar, Roy Fielding]
10509 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10510 r->filename. Since those two are meant to be in sync with each other
10511 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]

10520 reporting a select error over and over.
10521 [Rick Franchuk <rickf transpect.net>] PR#1107, 987, 588
10523 *) Fixed error in proxy_util.c when looping through multiple host IP
10524 addresses. [Lars Eilebrecht] PR#974
10526 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10527 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10528 bytes before writing, but it will never split a log entry across a
10529 buffer boundary. [Dean Gaudet]
10531 *) API: the short_score record has been split into two pieces, one which
10532 the parent writes on, and one which the child writes on. As part of
10533 this change the get_scoreboard_info() function was removed, and
10534 scoreboard_image was exported. This change fixes a race condition
10535 in file based scoreboard systems, and speeds up changes involving the
10536 scoreboard in earlier 1.3 development. [Dean Gaudet]
10538 *) API: New register_other_child() API (see http_main.h) which allows
10539 modules to register children with the parent for maintenance. It
10540 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10542 *) API: New piped_log API (see http_log.h) which implements piped logs,
10543 and will use register_other_child to implement reliable piped logs
10544 when it is available. The reliable piped logs part can be disabled
10545 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10546 logs is only available on Unix. [Dean Gaudet]
10548 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10549 meets_conditions(). This allows conditional HTTP selection to be
10550 handled separately from the storing of the header fields, and provides
10551 the ability for CGIs to set their own ETags for conditional checking.
10552 [Ken Coar, Roy Fielding] PR#895
10554 *) Changes to mod_log_config to allow naming of format strings.
10555 Format nicknames are defined with "LogFormat fmt nickname", and can
10556 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
10559 *) New module, "mod_speling", which can help find files even when
10560 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
10562 *) API: New function child_terminate() triggers the child process to
10563 exit, while allowing the child finish what it needs to for the
10564 current request first.
10565 [Doug MacEachern, Alexei Kosut]
10567 *) Windows now defaults to using full status reports with mod_status.
10568 [Alexei Kosut] PR #1094
10570 *) *Really* disable all mod_rewrite operations if the engine is off.
10571 Some things (like RewriteMaps) were checked/performed even if they
10572 weren't supposed to be. [Ken Coar] PR #991
10574 *) Implement a new timer scheme which eliminates the need to call alarm() all
10575 the time. Instead a counter in the scoreboard for each child is used to
10576 show when the child has made forward progress. The parent samples this
10577 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10578 progress has been made in the timeout period. This reduces the static
10579 request best-case syscall count to 22 from 29. This scheme is only
10580 used by systems with memory-based scoreboards. [Dean Gaudet]
10582 *) The proxy now properly handles CONNECT requests which are sent
10583 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10585 *) A script called apachectl has been added to the support
10586 directory. This script allows you to do things such as
10587 "apachectl start" and "apachectl restart" from the command
10588 line. [Marc Slemko]
10590 *) Modules and core routines are now put into libraries, which
10591 simplifies the link line tremendously (among other advantages).
10594 *) Some of the MD5 names defined in Apache have been renamed to have
10595 an `ap_' prefix to avoid conflicts with routines supplied by
10596 external libraries. [Ken Coar]
10598 *) Removal of mod_auth_msql.c from the distribution. There are many
10599 other options for databases today. Rather than offer one option,
10600 offer none at this time. mod_auth_msql and other SQL database
10601 authentication modules can be found at the Apache Module Registry.
10602 http://modules.apache.org/ It would be nice to offer a generic
10603 mod_auth_sql option in the near future.
10605 *) PORT: BeOS support added [Alexei Kosut]
10607 *) Configure no longer accepts the -make option, since it creates
10608 Makefile on the fly based on Makefile.tmpl and Configuration.
10610 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
10611 of forcibly killing off all its processes and exiting without
10612 cleaning up. [Alexei Kosut]
10614 *) API: A new field in the request_rec, r->mtime, has been added to
10615 avoid gratuitous parsing of date strings. It is intended to hold
10616 the last-modified date of the resource (if applicable). An
10617 update_mtime() routine has also been added to advance it if
10618 appropriate. [Roy Fielding, Ken Coar]
10620 *) SECURITY: If a htaccess file can not be read due to bad permissions,
10621 deny access to the directory with a HTTP_FORBIDDEN. The previous
10622 behavior was to ignore the htaccess file if it could not be read.
10623 This change may make some setups with unreadable htaccess files
10624 stop working. [Marc Slemko] PR#817
10626 *) Add aplog_error() providing a mechanism to define levels of
10627 verbosity to the server error logging. This addition also provides
10628 the ability to log errors using syslogd. Error logging is configurable
10629 on a per-server basis using the LogLevel directive. Conversion
10630 of log_*() in progress. [Randy Terbush]
10632 *) Further enhance aplog_error() to not log filename, line number, and
10633 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
10635 *) WIN32: Canonicalise filenames under Win32. Short filenames are
10636 converted to long ones. Backslashes are converted to forward
10637 slashes. Case is converted to lower. Parts of URLs that do not
10638 correspond to files are left completely alone. [Ben Laurie]
10640 *) PORT: 2 new OSs added to the list of ports:
10641 Encore's UMAX V: Arieh Markel <amarkel encore.com>
10642 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
10644 *) Add the server version (SERVER_VERSION macro) to the "server
10645 configured and running" entry in the error_log. Also build an
10646 object file at link-time that contains the current time
10647 (SERVER_BUILT global const char[]), and include that in the
10648 message. [Ken Coar]
10650 *) Set r->headers_out when sending responses from the proxy.
10651 This fixes things such as the logging of headers sent from
10652 the proxy. [Marc Slemko] PR#659
10654 *) support/httpd_monitor is no longer distributed because the
10655 scoreboard should not be file based if at all possible. Use
10656 mod_status to see current server snapshot.
10658 *) (set_file_slot): New function, allowing auth directives to be
10659 independent of the server root, so the server documents can be
10660 moved to a different directory or machine more easily.
10661 [David J. MacKenzie]
10663 *) If no TransferLog is given explicitly, decline
10664 to log. This supports coexistence with other logging modules,
10665 such as the custom one that UUNET uses. [David J. MacKenzie]
10667 *) Check for titles in server-parsed HTML files.
10668 Ignore leading newlines and returns in titles. The old behavior
10669 of replacing a newline after <title> with a space causes the
10670 title to be misaligned in the listing. [David J. MacKenzie]
10672 *) Change mod_cern_meta to be configurable on a per-directory basis.
10673 [David J. MacKenzie]
10675 *) Add 'Include' directive to allow inclusion of configuration
10676 files within configuration files. [Randy Terbush]
10678 *) Proxy errors on connect() are logged to the error_log (nothing
10679 new); now they include the IP address and port that failed
10680 (*that's* new). [Ken Coar, Marc Slemko] PR#352
10682 *) Various architectures now define USE_MMAP_FILES which causes
10683 the server to use mmap() for static files. There are two
10684 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
10685 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
10686 number of bytes written in one cycle from a single mmap()d object,
10687 default 32768). [Dean Gaudet]
10689 *) API: Added post_read_request API phase which is run right after reading
10690 the request from a client, or right after an internal redirect. It is
10691 useful for modules setting environment variables that depend only on
10692 the headers/contents of the request. It does not run during subrequests
10693 because subrequests inherit pretty much everything from the main
10694 request. [Dean Gaudet]
10696 *) Added mod_unique_id which is used to generate a unique identifier for
10697 each hit, available in the environment variable UNIQUE_ID.
10700 *) init_modules is now called after the error logs have been opened. This
10701 allows modules to emit information messages into the error logs.
10704 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10705 information for case where proxy module is not available. [Marc Slemko]
10707 *) PORT: Apache has need for mutexes to serialize its children around
10708 accept. In prior versions either fcntl file locking or flock file
10709 locking were used. The method is chosen by the definition of
10710 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
10711 and FLOCK for flock(). New options have been added:
10712 - SYSVSEM to use System V style semaphores
10713 - PTHREAD to use POSIX threads (appears to work on Solaris only)
10714 - USLOCK to use IRIX uslock
10715 Based on timing various techniques, the following changes were made
10717 - Linux 2.x uses flock instead of fcntl
10718 - Solaris 2.x uses pthreads
10719 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
10720 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
10721 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
10722 Martijn Koster <m.koster pobox.com>]
10724 *) PORT: The semantics of accept/select make it very desirable to use
10725 mutexes to serialize accept when multiple Listens are in use. But
10726 in the case where only a single socket is open it is sometimes
10727 redundant to serialize accept(). Not all unixes do a good job with
10728 potentially dozens of children blocked on accept() on the same
10729 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
10730 the server will avoid serialization when listening on only one socket,
10731 and use serialization when listening on multiple sockets.
10732 [Dean Gaudet] PR#467
10734 *) Configure changes: TestLib replaced by TestCompile, which has
10735 some additional capability (such as doing a sanity check of
10736 the compiler and flags selected); the version of Solaris is now
10737 available via the #define value of SOLARIS2; IRIX n32bit libs
10738 now supported and selectable by new Configuration Rule: IRIXN32;
10739 We no longer default to -O2 optimization. [Jim Jagielski]
10741 *) Updated Configure: Configuration now uses AddModule to specify
10742 module source or binary file location, relative to src directory.
10743 Modules can be dropped into modules/extra, or in their own
10744 directory, and modules can come with a Makefile or Configure can
10745 create one. Modules can add compiler or library information to
10746 generated Makefiles. [Paul Sutton]
10748 *) Source core re-organisation: distributed modules are now in
10749 modules/standard. All other source code is in main. OS-specific
10750 code is in os/{unix,emx,win32} directories. [Paul Sutton]
10752 *) mod_browser has been removed, since it's replaced by mod_setenvif.
10755 *) Fix another long-standing bug in sub_req_lookup_file where it would
10756 happily skip past access checks on subdirectories looked up with
10757 relative paths. (It's used by mod_dir, mod_negotiation,
10758 and mod_include.) [Dean Gaudet]
10760 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
10761 N is the number of <Directory> sections, and M is the number of
10762 components in the filename of an object.
10764 To achieve this optimization the following config changes were made:
10765 - Wildcards (* and ?, not the regex forms) in <Directory>s,
10766 <Files>s, and <Location>s now treat a slash as a special
10767 character. For example "/home/*/public_html" previously would
10768 match "/home/a/andrew/public_html", now it only matches things
10769 like "/home/bob/public_html". This mimics /bin/sh behaviour.
10770 - It's possible now to use [] wildcarding in <Directory>, <Files>
10772 - Regex <Directory>s are applied after all non-regex <Directory>s.
10776 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
10777 and corrupted paths. [Dean Gaudet]
10779 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
10780 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
10781 be accessed now via backreferences $1..$9 in RewriteConds test-against
10782 strings in addition to RewriteRules subst string. Second the grouped
10783 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
10784 via backreferences %1..%9 both in following RewriteCond test-against
10785 strings and RewriteRules subst string. This provides maximum flexibility
10786 through the use of backreferences.
10787 Additionally the rewriting engine was cleaned up by putting common
10788 code to the new expand_backrefs_inbuffer() function.
10789 [Ralf S. Engelschall]
10791 *) When merging the main server's <Directory> and <Location> sections into
10792 a vhost, put the main server's first and the vhost's second. Otherwise
10793 the vhost can't override the main server. [Dean Gaudet] PR#717
10795 *) The <Directory> code would merge and re-merge the same section after
10796 a match was found, possibly causing problems with some modules.
10799 *) ip-based vhosts are stored and queried using a hashing function, which
10800 has been shown to improve performance on servers with many ip-vhosts.
10801 Some other changes had to be made to accommodate this:
10802 - the * address for vhosts now behaves like _default_
10803 - the matching process now is:
10804 - match an ip-vhost directly via hash (possibly matches main
10806 - if that fails, just pretend it matched the main server
10807 - if so far only the main server has been matched, perform
10808 name-based lookups (ServerName, ServerAlias, ServerPath)
10809 *only on name-based vhosts*
10810 - if they fail, look for _default_ vhosts
10811 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
10813 *) dbmmanage overhaul:
10814 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
10815 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
10816 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
10817 - provide better seed for rand
10818 - prompt for password as per getpass(3) (turn off echo, read from
10820 - use "newstyle" crypt based on $Config{osname} ($^O)
10821 - will not add a user if already in database, use new `update' command
10823 - added `check' command to check a users' password
10824 - added `import' command to convert existing password text-files or
10825 dbm files exported with `view'
10826 - more descriptive usage, general cleanup, 'use strict' clean, etc.
10829 *) Added psocket() which is a pool form of socket(), various places within
10830 the proxy weren't properly blocking alarms while registering the cleanup
10831 for its sockets. bclose() now uses pclose() and pclosesocket(). There
10832 was a bug where the client socket was being close()d twice due a still
10833 registered cleanup. [Dean Gaudet]
10835 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
10838 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
10839 [Jason Venner <jason idiom.com>] PR#667
10841 *) Enable ``=""'' for RewriteCond directives to match against
10842 the empty string. This is the preferred way instead of ``^$''.
10843 [Ralf S. Engelschall]
10845 *) Fixed an infinite loop in mod_imap for references above the server root
10846 [Dean Gaudet] PR#748
10848 *) mod_proxy now has a ReceiveBufferSize directive, similar to
10849 SendBufferSize, so that the TCP window can be set appropriately
10850 for LFNs. [Phillip A. Prindeville]
10852 *) mod_browser has been replaced by the more general mod_setenvif
10853 (courtesy of Paul Sutton). BrowserMatch* directives are still
10854 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
10855 UnSetEnvIfZero directives. [Ken Coar]
10857 *) "HostnameLookups double" forces double-reverse DNS to succeed in
10858 order for remote_host to be set (for logging, or for the env var
10859 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
10862 *) mod_access overhaul:
10863 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
10864 and cidr syntax (i.e. 10.1.0.0/16). PR#762
10865 - Critical path was sped up by pre-computing a few things at config time.
10866 - The undocumented syntax "allow user-agents" was removed,
10867 the replacement is "allow from env=foobar" combined with mod_browser.
10868 - When used with hostnames it now forces a double-reverse lookup
10869 no matter what the directory settings are. This double-reverse
10870 doesn't affect any of the other routines that use the remote
10871 hostname. In particular it's still passed to CGIs and the log
10872 without the double-reverse check. Related PR#860.
10875 *) When a large bwrite() occurs (larger than the internal buffer size),
10876 while there is already something in the buffer, apache will combine
10877 the large write and the buffer into a single writev(). (This is
10878 in anticipation of using mmap() for reading files.)
10881 *) In obscure cases where a partial socket write occurred while chunking,
10882 Apache would omit the chunk header/footer on the next block. Cleaned
10883 up other bugs/inconsistencies in error conditions in buff.c. Fixed
10884 a bug where a long pause in DNS lookups could cause the last packet
10885 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
10887 *) API: Added child_exit function to module structure. This is called
10888 once per "heavy-weight process" just before a server child exit()'s
10889 e.g. when max_requests_per_child is reached, etc.
10890 [Doug MacEachern, Dean Gaudet]
10892 *) mod_include cleanup showed that handle_else was being used to handle
10893 endif. It didn't cause problems, but it was cleaned up too.
10896 *) mod_cern_meta would attempt to find meta files for the directory itself
10897 in some cases, but not in others. It now avoids it in all cases.
10900 *) mod_mime_magic would core dump if there was a decompression error.
10901 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
10903 *) PORT: some variants of DGUX require -lsocket -lnsl
10904 [Alexander L Jones <alex systems-options.co.uk>] PR#732
10906 *) mod_autoindex now allows sorting of FancyIndexed directory listings
10907 by the various fields (name, size, et cetera), either in ascending
10908 or descending order. Just click on the column header. [Ken Coar]
10910 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
10911 CPUs like the Alpha. Apache still stores ints in pointers, but that's
10912 the relatively safe direction. [Dean Gaudet] PR#344
10914 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
10915 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
10917 *) child_main avoids an unneeded call to select() when there is only one
10918 listening socket. [Dean Gaudet]
10920 *) In the event that the server is starved for idle servers it will
10921 spawn 1, then 2, then 4, ..., then 32 servers each second,
10922 doubling each second. It'll also give a warning in the errorlog
10923 since the most common reason for this is a poor StartServers
10924 setting. The define MAX_SPAWN_RATE can be used to raise/lower
10925 the maximum. [Dean Gaudet]
10927 *) Apache now provides an effectively unbuffered connection for
10928 CGI scripts. This means that data will be sent to the client
10929 as soon as the CGI pauses or stops output; previously, Apache would
10930 buffer the output up to a fixed buffer size before sending, which
10931 could result in the user viewing an empty page until the CGI finished
10932 or output a complete buffer. It is no longer necessary to use an
10933 "nph-" CGI to get unbuffered output. Given that most CGIs are written
10934 in a language that by default does buffering (e.g. perl) this
10935 shouldn't have a detrimental effect on performance.
10937 "nph-" CGIs, which formerly provided a direct socket to the client
10938 without any server post-processing, were not fully compatible with
10939 HTTP/1.1 or SSL support. As such they would have had to implement
10940 the transport details, such as encryption or chunking, in order
10941 to work properly in certain situations. Now, the only difference
10942 between nph and non-nph scripts is "non-parsed headers".
10943 [Dean Gaudet, Sameer Parekh, Roy Fielding]
10945 *) If a BUFF is switched from buffered to unbuffered reading the first
10946 bread() will return whatever remained in the buffer prior to the
10947 switch. [Dean Gaudet]
10949 Changes with Apache 1.3a1
10951 *) Added another Configure helper script: TestLib. It determines
10952 if a specified library exists. [Jim Jagielski]
10954 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
10955 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
10958 *) PORT: Some architectures use size_t for various lengths in network
10959 functions such as accept(), and getsockname(). The definition
10960 NET_SIZE_T is used to control this. [Dean Gaudet]
10962 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
10963 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
10964 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
10966 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
10967 [Igor N Kovalenko <infoh mail.wplus.net>]
10969 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
10970 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
10971 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
10972 [Dean Gaudet] related PR#875
10974 *) API: Correct child_init() slot declaration from int to void, to
10975 match the init() declaration. Update mod_example to use the new
10978 *) added transport handle slot (t_handle) to the BUFF structure
10981 *) get_client_block() returns wrong length if policy is
10982 REQUEST_CHUNKED_DECHUNK.

10990 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
10992 *) AddModuleInfo directive for mod_info which allows you to annotate
10993 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
10995 *) Added NoProxy directive to avoid using ProxyRemote for selected
10996 addresses. Added ProxyDomain directive to cause unqualified
10997 names to be qualified by redirection.
10998 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
11000 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
11001 header to the remote host in the proxy. [Sameer Parekh and
11004 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
11005 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
11006 URLs, fixed rewritelog(), fixed forced response code handling on
11007 redirects from within .htaccess files, disabled pipe locking under
11008 braindead SunOS 4.1.x, allow env variables to be set even on rules with
11009 no substitution, bugfixed situations where HostnameLookups is off, made
11010 mod_rewrite more thread-safe for NT port and fixed problem when creating
11011 an empty query string via "xxx?".
11012 This update also removes the copyright of Ralf S. Engelschall,
11013 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
11014 exclusively copyrighted by the Apache Group now. This happened because
11015 the author now has gifted mod_rewrite exclusively to the Apache Group and
11016 no longer maintains an external version.
11017 [Ralf S. Engelschall]
11019 *) API: Added child_init function to module structure. This is called
11020 once per "heavy-weight process" before any requests are handled.
11021 See http_config.h for more details. [Dean Gaudet]
11023 *) Anonymous_LogEmail was logging on each subrequest.
11024 [Dean Gaudet] PR#421, 868
11026 *) API: Added is_initial_req() which tests if the request being
11027 processed is the initial request, or a subrequest.
11030 *) Extended SSI (mod_include) now handles additional relops for
11031 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
11033 *) Configure fixed to correctly propagate user-selected options and
11034 settings (such as CC and OPTIM) to Makefiles other than
11035 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
11037 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
11038 directory indices to start with the contents of the HeaderName file
11039 if there is one. If there isn't one, the behaviour is unchanged.
11040 [Ken Coar, Roy Fielding, Andrey A. Chernov]
11042 *) WIN32: Modules can now be dynamically loaded DLLs using the
11043 LoadModule/LoadFile directives. Note that module DLLs must be
11044 compiled with the multithreaded DLL version of the runtime library.
11045 [Alexei Kosut and Ben Laurie]
11047 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
11048 This allows the admin to completely remove automatic indexing
11049 from the server, while still supporting the basic functions of
11050 trailing-slash redirects and DirectoryIndex files. Note that if
11051 you're carrying over an old Configuration file and you use directory
11052 indexing then you'll want to add:
11054 Module autoindex_module mod_autoindex.o
11056 before mod_dir in your Configuration. [Dean Gaudet]
11058 *) popendir/pclosedir created to properly protect directory scanning.
11059 [Dean Gaudet] PR#525
11061 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
11062 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
11063 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
11066 *) The AccessFileName directive can now take more than one filename.
11067 ["Lou D. Langholtz" <ldl usi.utah.edu>]
11069 *) The new mod_mime_magic can be used to "magically" determine the type
11070 of a file if the extension is unknown. Based on the unix file(1)
11071 command. [Ian Kluft <ikluft cisco.com>]
11073 *) We now determine and display the time spent processing a
11074 request if desired. [Jim Jagielski]
11076 *) mod_status: PID field of "dead" child slots no longer displays
11077 main httpd process's PID. [Jim Jagielski]
11079 *) Makefile.nt added - to build all the bits from the command line:
11080 nmake -f Makefile.nt
11081 Doesn't yet work properly. [Ben Laurie]
11083 *) Default text of 404 error is now "Not Found" rather than the
11084 potentially misleading "File Not Found". [Ken Coar]
11086 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
11087 for the net if we require people that actually need this data to
11088 enable it. [Linus Torvalds]
11090 *) directory_walk() is an expensive function, keep a little more state to
11091 avoid needless string counting. Add two new functions make_dirstr_parent
11092 and make_dirstr_prefix which replace all existing uses of make_dirstr.
11093 The new functions are a little less general than make_dirstr, but
11094 work more efficiently (less memory, less string counting).
11097 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
11098 to LDFLAGS) to avoid complications with lex rules in make files.
11099 [Dean Gaudet] PR#372
11101 *) run_method optimized to avoid needless scanning over NULLs in the
11102 module list. [Dean Gaudet]
11104 *) Revamp of (unix) scoreboard management code such that it avoids
11105 unnecessary traversals of the scoreboard on each hit. This is
11106 particularly important for high volume sites with a large
11107 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
11108 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
11109 httpd.h. [Dean Gaudet]
11111 *) In configurations using multiple Listen statements it was possible for
11112 busy sockets to starve other sockets of service. [Dean Gaudet]
11114 *) Added hook so standalone_main can be replaced at compile time
11115 (define STANDALONE_MAIN)
11118 *) Lowest-level read/write functions in buff.c will be replaced with
11119 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
11120 compile time. The default sfio discipline will behave as apache
11121 would without sfio compiled in.
11124 *) Enhance UserDir directive (mod_userdir) to accept a list of
11125 usernames for the 'disable' keyword, and add 'enable user...' to
11126 selectively *en*able userdirs if they're globally disabled.
11129 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
11130 will work with Netscape dbm files. (dbmmanage will probably not
11131 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
11133 *) Add a ListenBacklog directive to control the backlog parameter
11134 passed to listen(). Also change the default to 511 from 512.
11137 *) API: A new handler response DONE which informs apache that the
11138 request has been handled and it can finish off quickly, similar to
11139 how it handles errors. [Rob Hartill]
11141 *) Turn off chunked encoding after sending terminating chunk/footer
11142 so that we can't do it twice by accident. [Roy Fielding]
11144 *) mod_expire also issues Cache-Control: max-age headers.
11147 *) API: Added kill_only_once option for free_proc_chain so that it won't
11148 aggressively try to kill off specific children. For fastcgi.
11149 [Stanley Gambarin <gambarin OpenMarket.com>]
11151 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
11153 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
11154 When used together, these cause mod_dir to emit HEIGHT and WIDTH
11155 attributes in the FancyIndexing IMG tags. [Ken Coar]
11157 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
11159 *) PORT: Added Windows NT support
11160 [Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
11162 Changes with Apache 1.2.6
11164 *) mod_include when using XBitHack Full would send ETags in addition to
11165 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.

11168 *) SECURITY: When a client connects to a particular port/addr, and
11169 gives a Host: header ensure that the virtual host requested can
11170 actually be reached via that port/addr. [Ed Korthof <ed organic.com>]

11201 *) r->connection->user was allocated in the wrong pool causing corruption
11202 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
11204 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
11205 Also removed the auto-generated link to www.apache.org that was the
11206 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
11208 *) Multiple "close" tokens may have been set in the "Connection"
11209 header, not an error, but a waste.
11210 [<Ronald.Tschalaer psi.ch>] PR#1683
11212 *) "basic" and "digest" auth tokens should be tested case-insensitive.
11213 [<Ronald.Tschalaer psi.ch>] PR#1599, PR#1666
11215 *) It appears the "257th byte" bug (see
11216 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
11217 at the 256th byte as well. Fixed. [Dean Gaudet]
11219 *) mod_rewrite would not handle %3f properly in some situations.
11222 *) Apache could generate improperly chunked HTTP/1.1 responses when
11223 the bputc() or rputc() functions were used by modules (such as
11224 mod_include). [Dean Gaudet]
11226 *) #ifdef wrap a few #defines in httpd.h to make life easier on
11227 some ports. [Ralf Engelschall]
11229 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
11231 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
11233 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
11235 Changes with Apache 1.2.5
11237 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
11238 only an issue on systems without a MAXDNAME define or where
11239 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
11241 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
11244 *) Fix core dump in the ftp proxy when reading incorrectly formatted
11245 directory listings. [Marc Slemko]
11247 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
11250 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
11251 is used to read various types of files such as htaccess and
11252 htpasswd files. [Marc Slemko]
11254 *) SECURITY: Ensure that the buffer returned by ht_time is always
11255 properly null terminated. [Marc Slemko]
11257 *) SECURITY: General mod_include cleanup, including fixing several
11258 possible buffer overflows and a possible infinite loop. This cleanup
11259 was done against 1.3 code and then backported to 1.2, the result
11260 is a large difference (due to indentation cleanup in 1.3 code).
11261 Users interested in seeing a smaller set of relevant differences
11262 should consider comparing against src/modules/standard/mod_include.c
11263 from the 1.3b3 release. Non-indentation changes to mod_include
11264 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
11266 *) SECURITY: Numerous changes to mod_imap in a general cleanup
11267 including fixing a possible buffer overflow. This cleanup also
11268 was done with 1.3 code as a basis, see the the previous note
11269 about mod_include. [Dean Gaudet]
11271 *) SECURITY: If a htaccess file can not be read due to bad
11272 permissions, deny access to the directory with a HTTP_FORBIDDEN.
11273 The previous behavior was to ignore the htaccess file if it could not
11274 be read. This change may make some setups with unreadable
11275 htaccess files stop working. PR#817 [Marc Slemko]
11277 *) SECURITY: no2slash() was O(n^2) in the length of the input.
11278 Make it O(n). This inefficiency could be used to mount a denial
11279 of service attack against the Apache server. Thanks to
11280 Michal Zalewski <lcamtuf boss.staszic.waw.pl> for reporting
11281 this. [Dean Gaudet]

11291 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
11292 r->filename. Since those two are meant to be in sync with each other
11293 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]

11312 on this platform. [Marc Slemko]
11314 Changes with Apache 1.2.3
11316 *) The request to a remote proxy was mangled if it was generated as the
11317 result of a ProxyPass directive. URL schemes other than http:// were not
11318 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

11321 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11322 information for case where proxy module is not available. [Marc Slemko]
11324 *) Force proxy to always respond as HTTP/1.0, which it was failing to
11325 do for errors and cached responses. [Roy Fielding]
11327 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
11329 Changes with Apache 1.2.2 [not released]
11331 *) Fixed another long-standing bug in sub_req_lookup_file where it would
11332 happily skip past access checks on subdirectories looked up with relative
11333 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
11336 *) Add lockfile name to error message printed out when
11337 USE_FLOCK_SERIALIZED_ACCEPT is defined.
11340 *) Enhanced the chunking and error handling inside the buffer functions.
11341 [Dean Gaudet, Roy Fielding]
11343 *) When merging the main server's <Directory> and <Location> sections into
11344 a vhost, put the main server's first and the vhost's second. Otherwise
11345 the vhost can't override the main server. [Dean Gaudet] PR#717
11347 *) The <Directory> code would merge and re-merge the same section after
11348 a match was found, possibly causing problems with some modules.
11351 *) Fixed an infinite loop in mod_imap for references above the server root.
11352 [Dean Gaudet] PR#748
11354 *) mod_include cleanup showed that handle_else was being used to handle
11355 endif. It didn't cause problems, but it was cleaned up too.
11358 *) Last official synchronization of mod_rewrite with author version (because
11359 mod_rewrite is now directly developed by the author at the Apache Group):
11360 o added diff between mod_rewrite 3.0.6+ and 3.0.9
11361 minus WIN32/NT stuff, but plus copyright removement.
11363 - workaround for detecting infinite rewriting loops
11364 - fixed setting of env vars when "-" is used as subst string

11368 - fix for rewritelog in cases where remote hostname is unknown
11369 - fixed totally damaged request_rec walk-back loop
11370 o remove static from local data and add static to global ones.
11371 o replaced ugly proxy finding stuff by simple
11372 find_linked_module("mod_proxy") call.
11373 o added missing negation char on rewritelog()
11374 o fixed a few comment typos

11380 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11381 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11382 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

11384 a deficiency in the header_parse phase.

11402 under Solaris 2.x (up through 2.5.1). It has been fixed.
11403 [Dean Gaudet] PR#832
11405 *) API: In HTTP/1.1, whether or not a request message contains a body
11406 is independent of the request method and based solely on the presence
11407 of a Content-Length or Transfer-Encoding. Therefore, our default
11408 handlers need to be prepared to read a body even if they don't know
11409 what to do with it; otherwise, the body would be mistaken for the
11410 next request on a persistent connection. discard_request_body()
11411 has been added to take care of that. [Roy Fielding] PR#378
11413 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
11414 release version number, such that it always increases along the
11415 same lines as our source code branching. [Roy Fielding]
11417 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
11419 Changes with Apache 1.2.1
11421 *) SECURITY: Don't serve file system objects unless they are plain files,
11422 symlinks, or directories. This prevents local users from using pipes
11423 or named sockets to invoke programs for an extremely crude form of

11427 could contain "../" allowing a local user to "publish" any file on
11428 the system. No slashes are allowed now. [Dean Gaudet]
11430 *) SECURITY: It was possible to violate the symlink Options using mod_dir
11431 (headers, readmes, titles), mod_negotiation (type maps), or
11432 mod_cern_meta (meta files). [Dean Gaudet]
11434 *) SECURITY: Apache will refuse to run as "User root" unless
11435 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
11437 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
11438 if it contained a .htaccess disallowing symlinks. This is contrary
11439 to the rule that symlink permissions are tested with the symlink
11440 options of the parent directory. [Dean Gaudet] PR#353
11442 *) CONFIG: The LockFile directive can be used to place the serializing
11443 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
11444 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
11447 *) Request processing now retains state of whether or not the request
11448 body has been read, so that internal redirects and subrequests will
11449 not try to read it twice (and block). [Roy Fielding]
11451 *) Add a placeholder in modules/Makefile to avoid errors with certain
11452 makes. [Marc Slemko]
11454 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

11460 *) Attempt to work around problems with third party libraries that do not
11461 handle high numbered descriptors (examples include bind, and
11462 solaris libc). On all systems apache attempts to keep all permanent
11463 descriptors above 15 (called the low slack line). Solaris users
11464 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
11465 which keeps all non-FILE * descriptors above 255. On all systems
11466 this should make supporting large numbers of vhosts with many open
11467 log files more feasible. If this causes trouble please report it,
11468 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
11469 [Dean Gaudet] various PRs
11471 *) Related to the last entry, network sockets are now opened before
11472 log files are opened. The only known case where this can cause
11473 problems is under Solaris with many virtualhosts and many Listen
11474 directives. But using -DHIGH_SLACK_LINE=256 described above will
11475 work around this problem. [Dean Gaudet]

11526 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
11527 [Doug MacEachern, Rob Hartill]
11529 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
11530 reading from one buffer and writing to another, at least until it has
11531 a custom timeout handler. [Roy Fielding and Petr Lampa]
11533 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
11534 apparently due to a mismatch between sigaction and setjmp.

11541 *) Virtual hosts with the same ServerName, but on different ports, were
11542 not being selected properly. [Ed Korthof]

11549 *) If multiple requests on a single connection are used to retrieve
11550 data from different virtual hosts, the virtual host list would be
11551 scanned starting with the most recently used VH instead of the first,

11572 CC=/OPTIM= format in Configuration. Finally, fix compiler
11573 flags if using HP-UX's cc compiler. [Jim Jagielski]
11575 *) Subrequests and internal redirects now inherit the_request from the
11576 original request-line. [Roy Fielding]
11578 *) Test for error conditions before creating output header fields, since
11579 we don't want the error message to include those fields. Likewise,
11580 reset the content_language(s) and content_encoding of the response
11581 before generating or redirecting to an error message, since the new
11582 message will have its own Content-* definitions. [Dean Gaudet]
11584 *) Restored the semantics of headers_out (headers sent only with 200..299
11585 and 304 responses) and err_headers_out (headers sent with all responses).
11586 Avoid the overhead of copying tables if err_headers_out is empty
11587 (the usual case). [Roy Fielding]
11589 *) Fixed a couple places where a check for the default Content-Type was
11590 not properly checking both the value configured by the DefaultType
11591 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
11592 of DEFAULT_TYPE to match the documented default (text/plain).

11598 *) Properly initialize the flock structures used by the mutex locking
11599 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
11602 *) The method for determining PATH_INFO has been restored to the pre-1.2b
11603 (and NCSA httpd) definition wherein it was the extra path info beyond
11604 the CGI script filename. The environment variable FILEPATH_INFO has
11605 been removed, and instead we supply the original REQUEST_URI to any
11606 script that wants to be Apache-specific and needs the real URI path.
11607 This solves a problem with existing scripts that use extra path info
11608 in the ScriptAlias directive to pass options to the CGI script.
11611 *) The _default_ change in 1.2b10 will change the behaviour on configs
11612 that use multiple Listen statements for listening on multiple ports.
11613 But that change is necessary to make _default_ consistent with other
11614 forms of <VirtualHost>. It requires such configs to be modified
11615 to use <VirtualHost _default_:*>. The documentation has been
11616 updated. [Dean Gaudet] PR#530
11618 *) If an ErrorDocument CGI script is used to respond to an error
11619 generated by another CGI script which has already read the message
11620 body of the request, the server would block trying to read the
11621 message body again. [Rob Hartill]

11644 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
11645 changes and in anticipation of 1.2 final release. [Roy Fielding]
11647 *) Fix problem with scripts not receiving a SIGPIPE when client drops
11648 the connection (e.g., when user presses Stop). Apache will now stop

11655 and relative order (and maybe even reduce some overhead).
11656 [Roy Fielding and Sameer Parekh]
11658 *) Fix graceful restart. Eliminate many signal-related race
11659 conditions in both forms of restart, and in SIGTERM. See

11700 parsing of headers. If the terminating empty-line CRLF occurs starting
11701 at the 256th or 257th byte of output, then Navigator will think a normal
11702 image is invalid. We are guessing that this is because their initial
11703 read of a new request uses a 256 byte buffer. We check the bytes written
11704 so far and, if we are about to tickle the bug, we instead insert a
11705 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

11762 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
11763 to it. [Marc Slemko]
11765 *) The addition of <Location> and <File> directives made the
11766 sub_req_lookup_simple() function bogus, so we now handle
11767 the special cases directly. [Dean Gaudet]
11769 *) We now try to log where the server is dumping core when a fatal
11770 signal is received. [Ken Coar]
11772 *) Improved lingering_close by adding a special timeout, removing the
11773 spurious log messages, removing the nonblocking settings (they
11774 are not needed with the better timeout), and adding commentary
11775 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
11776 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
11778 *) Send error messages about setsockopt failures to the server error
11779 log instead of stderr. [Roy Fielding]
11781 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
11783 *) Stopgap solution for CGI 3-second delay with server-side includes: if
11784 processing a subrequest, allocate memory from r->main->pool instead
11785 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
11786 in the middle of an SSI request. [Dean Gaudet] PR #122
11788 *) Fixed status of response when POST is received for a nonexistent URL
11789 (was sending 405, now 404) and when any method is sent with a
11790 full-URI that doesn't match the server and the server is not acting
11791 as a proxy (was sending 501, now 403). [Roy Fielding]
11793 *) Host port changed to unsigned short. [Ken Coar] PR #276
11795 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
11797 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
11799 *) Report extra info from errno with many errors that cause httpd to exit.
11800 spawn_child, popenf, and pclosef now have valid errno returns in the
11801 event of an error. Correct problems where errno was stomped on
11802 before being reported. [Dean Gaudet]
11804 *) In the proxy, if the cache filesystem was full, garbage_coll() was
11805 never called, and thus the filesystem would remain full indefinitely.
11806 We now also remove incomplete cache files left if the origin server
11807 didn't send a Content-Length header and either the client has aborted
11808 transfer or bwrite() to client has failed. [Petr Lampa]
11810 *) Fixed the handling of module and script-added header fields.
11811 Improved the interface for sending header fields and reduced
11812 the duplication of code between sending okay responses and errors.
11813 We now always send both headers_out and err_headers_out, and
11814 ensure that the server-reserved fields are not being overridden,
11815 while not overriding those that are not reserved. [Roy Fielding]
11817 *) Moved transparent content negotiation fields to err_headers_out
11818 to reflect above changes. [Petr Lampa]
11820 *) Fixed the determination of whether or not we should make the
11821 connection persistent for all of the cases where some other part
11822 of the server has already indicated that we should not. Also
11823 improved the ordering of the test so that chunked encoding will
11824 be set whenever it is desired instead of only when KeepAlive
11825 is enabled. Added persistent connection capability for most error
11826 responses (those that do not indicate a bad input stream) when
11827 accessed by an HTTP/1.1 client. [Roy Fielding]
11829 *) Added missing timeouts for sending header fields, error responses,
11830 and the last chunk of chunked encoding, each of which could have
11831 resulted in a process being stuck in write forever. Using soft_timeout
11832 requires that the sender check for an aborted connection rather than
11833 continuing after an EINTR. Timeouts that used to be initiated before
11834 send_http_header (and never killed) are now initiated only within or
11835 around the routines that actually do the sending, and not allowed to
11836 propagate above the caller. [Roy Fielding]
11838 *) mod_auth_anon required an @ or a . in the email address, not both.
11841 *) per_dir_defaults weren't set correctly until directory_walk for
11842 name-based vhosts. This fixes an obscure bug with the wrong config
11843 info being used for vhosts that share the same ip as the server.
11846 *) Improved generation of modules/Makefile to be more generic for
11847 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
11849 *) Generate makefile dependency for Configuration based on the actual
11850 name given when running the Configure process. [Dean Gaudet]
11852 *) Fixed problem with vhost error log not being set prior to
11853 initializing virtual hosts. [Dean Gaudet]
11855 *) Fixed infinite loop when a trailing slash is included after a type map
11856 file URL (extra path info). [Petr Lampa]
11858 *) Fixed server status updating of per-connection counters. [Roy Fielding]
11860 *) Add documentation for DNS issues (reliability and security), and try
11861 to explain the virtual host matching process. [Dean Gaudet]
11863 *) Try to continue gracefully by disabling the vhost if a DNS lookup
11864 fails while parsing the configuration file. [Dean Gaudet]
11866 *) Improved calls to setsockopt. [Roy Fielding]
11868 *) Negotiation changes: Don't output empty content-type in variant list;
11869 Output charset in variant list; Return sooner from handle_multi() if
11870 no variants found; Add handling of '*' wildcard in Accept-Charset.
11871 [Petr Lampa and Paul Sutton]
11873 *) Fixed overlaying of request/sub-request notes and headers in
11874 mod_negotiation. [Dean Gaudet]
11876 *) If two variants' charset quality are equal and one is the default
11877 charset (iso-8859-1), then prefer the variant that was specifically
11878 listed in Accept-Charset instead of the default. [Petr Lampa]
11880 *) Memory allocation problem in push_array() -- it would corrupt memory
11881 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
11883 *) invoke_handler() doesn't handle mime arguments in content-type
11884 [Petr Lampa] PR#160
11886 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
11889 *) Fixed problem with ErrorDocument not working for virtual hosts
11890 due to one of the performance changes in 1.2b7. [Dean Gaudet]
11892 *) Log an error message if we get a request header that is too long,
11893 since it may indicate a buffer overflow attack. [Marc Slemko]
11895 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
11896 not reject URLs without a double-slash, as per RFC2068 section 3.2.
11897 [Ken Coar] PR #146, #187
11899 *) Added table entry placeholder for new header_parser callback
11900 in all of the distributed modules. [Ken Coar] PR #191
11902 *) Allow for cgi files without the .EXE extension on them under OS/2.
11903 [Garey Smiley] PR #59
11905 *) Fixed error message when resource is not found and URL contains
11906 path info. [Petr Lampa and Dean Gaudet] PR #40
11908 *) Fixed user and server confusion over what should be a virtual host
11909 and what is the main server, resulting in access to something
11910 other than the name defined in the virtualhost directive (but
11911 with the same IP address) failing. [Dean Gaudet]
11913 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
11914 AIX; improves the redirection stuff to enable the users to generally
11915 redirect to http, https, gopher and ftp; added TIME variable for
11916 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
11917 special patterns >STRING, <STRING and =STRING to RewriteCond, which
11918 can be used in conjunction with %{TIME} or other variables to create
11919 time-dependent rewriting rules. [Ralf S. Engelschall]
11921 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
11922 Module authors may need to adjust their code for proper cleanup to take
11923 place (that is, call note_cleanups_for_fd()). This change fixes problems
11924 with file descriptors being erroneously closed when the proxy module was
11925 in use. [Ben Laurie]
11927 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
11928 initgroups() to hose the group information needed for later
11929 comparisons. [Randy Terbush]
11931 *) Remove unnecessary call to va_end() in create_argv() which
11932 caused a SEGV on some systems.
11934 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
11937 *) Clear memory allocated for listeners. [Randy Terbush]
11939 *) Improved handling of IP address as a virtualhost address and
11940 introduced "_default_" as a synonym for the default vhost config.
11941 [Dean Gaudet] PR #212
11943 Changes with Apache 1.2b7
11945 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
11947 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
11949 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
11950 - replace protocol response numbers with symbols
11951 - save variant-list into main request notes
11952 - free allocated memory from subrequests
11953 - merge notes, headers_out and err_headers_out
11955 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
11956 "HTTP/#.# ###*" to be more lenient about what we accept.
11959 *) more proxy FTP bug fixes:
11960 - Changed send_dir() to remove user/passwd from displayed URL.
11961 - Changed login error messages to be more descriptive.
11962 - remove setting of SO_DEBUG socket option
11963 - Make ftp_getrc() more lenient about multiline responses,
11964 specifically, 230 responses which don't have continuation 230-
11965 on each line). These seem to be all NT FTP servers, and while
11966 perhaps questionable, they appear to be legal by RFC 959.
11967 - Add missing kill_timeout() after transfer to user completes.
11970 *) Fixed problem where a busy server could hang when restarting
11971 after being sent a SIGHUP due to child processes not exiting.
11974 *) Modify mod_include escaping so a '\' only signifies an escaped
11975 character if the next character is one that needs
11976 escaping. [Ben Laurie]
11978 *) Eliminated possible infinite loop in mod_imap when relative URLs are
11979 used with a 'base' directive that does not have a '/' in it.
11980 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
11982 *) Reduced the default timeout from 1200 seconds to 300, and the
11983 one in the sample configfile from 400 to 300. [Marc Slemko]
11985 *) Stop vbprintf from crashing if given a NULL string pointer;
11986 print (null) instead. [Ken Coar]
11988 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
11989 [Marc Slemko and Roy Fielding]
11991 *) Fixed problem with mod_cgi-generated internal redirects trying to
11992 read the request message-body twice. [Archie Cobbs and Roy Fielding]
11994 *) Reduced timeout on lingering close, removed possibility of a blocked
11995 read causing the child to hang, and stopped logging of errors if
11996 the socket is not connected (reset by client). [Roy Fielding]
11998 *) Rearranged main child loop to remove duplication of code in
11999 select/accept and keep-alive requests, fixed several bugs regarding
12000 checking scoreboard_image for exit indication and failure to
12001 account for all success conditions and trap all error conditions,
12002 prevented multiple flushes before closing the socket; close the entire
12003 socket buffer instead of just one descriptor, prevent logging of
12004 EPROTO and ECONNABORTED on platforms where supported, and generally
12005 improved readability. [Roy Fielding]
12007 *) Extensive performance improvements. Cleaned up inefficient use of
12008 auto initializers, multiple is_matchexp calls on a static string,
12009 and excessive merging of response_code_strings. [Dean Gaudet]
12011 *) Added double-buffering to mod_include to improve performance on
12012 server-side includes. [Marc Slemko]
12014 *) Several fixes for suexec wrapper. [Randy Terbush]
12015 - Make wrapper work for files on NFS filesystem.
12016 - Fix portability problem of MAXPATHLEN.
12017 - Fix array overrun problem in clean_env().
12018 - Fix allocation of PATH environment variable
12020 *) Removed extraneous blank line is description of mod_status chars.
12023 *) Logging of errors from the call_exec routine simply went nowhere,
12024 since the logfile fd has been closed, so now we send them to stderr.
12025 [Harald T. Alvestrand]
12027 *) Fixed core dump when DocumentRoot is a CGI.
12028 [Ben Laurie, reported by <geddis tesserae.com>]
12030 *) Fixed potential file descriptor leak in mod_asis; updated it and
12031 http_core to use pfopen/pfclose instead of fopen/fclose.
12032 [Randy Terbush and Roy Fielding]
12034 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
12035 as the DEC Alpha which is 64-bit but uses 32-bit ints.
12036 [Dean Gaudet and Ken Coar]
12038 *) Return a 302 response code to the client when sending a redirect
12039 due to a missing trailing '/' on a directory instead of a 301; now
12040 it is cacheable. [Markus Gyger]
12042 *) Fix condition where, if a bad directive occurs in .htaccess, and
12043 sub_request() goes first to this directory, then log_reason() will
12044 SIGSEGV because it doesn't have initialized r->per_dir_config.
12045 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
12047 *) Fix handling of lang_index in is_variant_better(). This was
12048 causing problems which resulted in the server sending the
12049 wrong language document in some cases. [Petr Lampa]
12051 *) Remove free() from clean_env() in suexec wrapper. This was nuking
12052 the clean environment on some systems.
12054 *) Tweak byteserving code (e.g. serving PDF files) to work around
12055 bugs in Netscape Navigator and Microsoft Internet Explorer.
12056 Emit Content-Length header when sending multipart/byteranges.
12059 *) Port to HI-UX/WE2. [Nick Maclaren]
12061 *) Port to HP MPE operating system for HP 3000 machines
12062 [Mark Bixby <markb cccd.edu>]
12064 *) Fixed bug which caused a segmentation fault if only one argument
12065 given to RLimit* directives. [Ed Korthof]
12067 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
12069 *) Improved buffered output to the client by delaying the flush decision
12070 until the BUFF code is actually about to read the next request.
12071 This fixes a problem introduced in 1.2b5 with clients that send
12072 an extra CRLF after a POST request. Also improved chunked output
12073 performance by combining writes using writev() and removing as
12074 many bflush() calls as possible. NOTE: Platforms without writev()
12075 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
12076 or Configure, unless we have already done so. [Dean Gaudet]
12078 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
12080 *) Fixed mod_info output corruption bug introduced by buffer overflow
12081 fixes. [Dean Gaudet]
12083 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
12084 for the special case of a 304 response. [Paul Sutton]
12086 *) Improved handling of TRACE method by bypassing normal method handling
12087 and header parsing routines; fixed Allow response to always allow TRACE.
12090 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
12092 *) Cleaned-up some of the generated HTML. [Ken Coar]
12094 Changes with Apache 1.2b6
12096 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
12098 *) Fix typo introduced in fix for potential infinite loop around
12099 accept() in child_main(). This change caused the rev to 1.2b6.
12100 1.2b5 was never a public beta.
12102 Changes with Apache 1.2b5
12104 *) Change KeepAlive semantics (On|Off instead of a number), add
12105 MaxKeepAliveRequests directive. [Alexei Kosut]
12107 *) Various NeXT compilation patches, as well as a change in
12108 regex/regcomp.c since that file also used a NEXT define.
12111 *) Allow * to terminate the end of a directory match in mod_dir.
12112 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
12114 *) Don't call can_exec() if suexec_enabled. Calling this requires
12115 scripts executed by the suexec wrapper to be world executable, which
12116 defeats one of the advantages of running the wrapper. [Randy Terbush]
12118 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
12121 *) Migration from sprintf() to snprintf() to avoid buffer
12122 overflows. [Marc Slemko]
12124 *) Provide portable snprintf() implementation (ap_snprintf)
12125 as well as *cvt family. [Jim Jagielski]
12127 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
12130 *) Remove mod_fastcgi.c from the distribution. This module appears
12131 to be maintained more through the Open Market channels and should
12132 continue to be easily available at http://www.fastcgi.com/
12134 *) Fixed bug in modules/Makefile that wouldn't allow building in more
12135 than one subdirectory (or cleaning, either). [Jeremy Laidman]
12137 *) mod_info assumed that the config files were relative to ServerRoot.
12140 *) CGI scripts called as an error document resulting from failed
12141 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
12143 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
12146 *) Properly check errno to prevent display of a directory index
12147 when server receives a long enough URL to confuse stat().
12150 *) Several security enhancements to suexec wrapper. It is _highly_
12151 recommended that previously installed versions of the wrapper
12152 be replaced with this version. [Randy Terbush, Jason Dour]
12154 - ~user execution now properly restricted to ~user's home
12155 directory and below.
12156 - execution restricted to UID/GID > 100
12157 - restrict passed environment to known variables
12158 - call setgid() before initgroups() (portability fix)
12159 - remove use of setenv() (portability fix)
12161 *) Add HTTP/1.0 response forcing. [Ben Laurie]
12163 *) Add access control via environment variables. [Ben Laurie]
12165 *) Add rflush() function. [Alexei Kosut]
12167 *) remove duplicate pcalloc() call in new_connection().
12169 *) Fix incorrect comparison which could allow number of children =
12170 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
12171 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
12173 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
12174 AIX PS/2, CONVEXOS. [Jim Jagielski]
12176 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
12177 It's more portable. [Martin Kraemer]
12179 *) Replace references to make in Makefile.tmpl with $(MAKE).
12182 *) Add ProxyBlock directive w/IP address caching. Add IP address
12183 caching to NoCache directive as well. ProxyBlock works with all
12184 handlers; NoCache now also works with FTP for anonymous logins.
12185 Still more code cleanup. [Chuck Murcko]
12187 *) Add "header parse" API hook [Ben Laurie]
12189 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
12191 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
12193 *) Correctly allow access and auth directives in <Files> sections in
12194 server config files. [Alexei Kosut]
12196 *) Fix bug with ServerPath that could cause certain files to be not
12197 found by the server. [Alexei Kosut]
12199 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
12200 double-quote from text and so that it properly checks for unsupported
12201 status codes using the new index_of_response interface. [Roy Fielding]
12203 *) Multiple fixes to the lingering_close code in order to avoid being
12204 interrupted by a stray timeout, to avoid lingering on a connection
12205 that has already been aborted or never really existed, to ensure that
12206 we stop lingering as soon as any error condition is received, and to
12207 prevent being stuck indefinitely if the read blocks. Also improves
12208 reporting of error conditions. [Marc Slemko and Roy Fielding]
12210 *) Fixed initialization of parameter structure for sigaction.
12211 [<mgyger itr.ch>, Adrian Filipi-Martin]
12213 *) Fixed reinitializing the parameters before each call to accept and
12214 select, and removed potential for infinite loop in accept.
12215 [Roy Fielding, after useful PR from <adrian virginia.edu>]
12217 *) Fixed condition where, if a child fails to fork, the scoreboard would
12218 continue to say SERVER_STARTING forever. Eventually, the main process
12219 would refuse to start new children because count_idle_servers() will
12220 count those SERVER_STARTING entries and will always report that there
12221 are enough idle servers. [Phillip Vandry]
12223 *) Fixed bug in bcwrite regarding failure to account for partial writes.
12224 Avoided calling bflush() when the client is pipelining requests.
12225 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
12227 *) Added description of "." mode in server-status [Jim Jagielski]
12229 Changes with Apache 1.2b4
12231 *) Fix possible race condition in accept_mutex_init() that
12232 could leave a small security hole open allowing files to be
12233 overwritten in cases where the server UID has write permissions.
12236 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
12238 *) Fix portablity problem in util_script where ARG_MAX may not be
12239 defined for some systems.
12241 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
12244 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
12245 style magic #! token for better script portability. [Garey Smiley]
12247 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
12248 execution for ~userdir CGI. [Jason Dour]
12250 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
12252 *) Fix month off by one in suexec wrapper logging.
12254 Changes with Apache 1.2b3:
12256 *) Fix error in mod_cgi which could cause resources not to be properly
12257 freed, or worse. [Dean Gaudet]
12259 *) Fix find_string() NULL pointer dereference. [Howard Fear]
12261 *) Add set_flag_slot() at the request of Dirk and others.
12264 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
12266 *) Add changes to improve the error message given for invalid
12267 ServerName parameters. [Dirk vanGulik]
12269 *) Add "Authoritative" directive for Auth modules that don't
12270 currently have it. This gives admin control to assign authoritative
12271 control to an authentication scheme and allow "fall through" for
12272 those authentication modules that aren't "Authoritative" thereby
12273 allowing multiple authentication mechanisms to be chained.
12276 *) Remove requirement for ResourceConfig/AccessConfig if not using
12277 the three config file layout. [Randy Terbush]
12279 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
12281 *) Changes to suexec wrapper to fix the following problems:
12282 1. symlinked homedirs will kill ~userdirs.
12283 2. initgroups() on Linux 2.0.x clobbers gr->grid.
12284 3. CGI command lines paramters problems
12285 4. pw-pwdir for "docroot check" still the httpd user's pw record.
12286 [Randy Terbush, Jason Dour]
12288 *) Change create_argv() to accept variable arguments. This fixes
12289 a problem where arguments were not getting passed to the CGI via
12290 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
12292 *) Collapse multiple slashes in path URLs to properly apply
12293 handlers defined by <Location>. [Alexei Kosut]
12295 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
12297 *) Improve the accuracy of request duration timings by setting
12298 r->request_time in read_request_line() instead of read_request().
12301 *) Reset timeout while reading via get_client_block() in mod_cgi.c
12302 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
12304 *) Add the ability to pass different Makefile.tmpl files to Configure
12305 using the -make flag. [Rob Hartill]
12307 *) Fix coredump triggered when sending a SIGHUP to the server caused
12308 by an assertion failure, in turn caused by an uninitialised field in a
12312 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
12313 PATH_INFO from previous versions of Apache (in certain situations,
12314 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
12315 [later removed in 1.2b11]
12317 *) Add rwrite() function to API to allow for sending strings of
12318 arbitrary length. [Doug MacEachern]
12320 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
12322 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
12323 NeXT. [Jim Jagielski]
12325 *) Removed recent modification to promote the status code on internal
12326 redirects, since the correct fix was to change the default log format
12327 in mod_log_config so that it outputs the original status. [Rob Hartill]
12329 Changes with Apache 1.2b2:
12331 *) Update set_signals() to use sigaction() for setting handlers.
12332 This appears to fix a re-entrant problem in the seg_fault()
12333 bus_error() handlers. [Randy Terbush]
12335 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
12337 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
12339 *) proxy_http.c bugfixes: [Chuck Murcko]
12340 1) fixes possible NULL pointer reference w/NoCache
12341 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
12342 host would cache nothing if it was in the local domain,
12343 and the local domain was in the NoCache list)
12344 3) Adds Host: header when not available
12345 4) Some code cleanup and clarification
12347 *) mod_include.c bugfixes:
12348 1) Fixed an ommission that caused include variables to not
12349 be parsed in config errmsg directives [Howard Fear]
12350 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
12351 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
12352 4) Allow backslash-escaping to all quoted text
12353 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
12354 5) Pass variable to command line if not set in XSSI's env
12357 *) Fix infinite loop when processing Content-language lines in
12358 type-map files. [Alexei Kosut]
12360 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
12362 *) Fixed problem in set_[user|group] that prevented CGI execution
12363 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
12365 *) Added PORTING information file. [Jim Jagielski]
12367 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
12369 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
12371 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
12372 USE_FCNTL_SERIALIZED_ACCEPT was intended.
12374 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
12375 which caused problems of systems where socket s_addr is >32bits.
12377 *) Added comment to explain (r->chunked = 1) side-effect in
12378 http_protocol.c [Roy Fielding]
12380 *) Replaced use of index() in mod_expires.c with more appropriate
12381 and portable isdigit() test. [Ben Laurie]
12383 *) Updated Configure for ...
12384 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
12385 *-dg-dgux* (bad pattern match)
12386 QNX (DEF_WANTHSREGEX=yes)
12387 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
12389 *-unixware211 (new)
12390 and added some user diagnostic info. [Ben Laurie]
12392 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
12393 for better portability. [Jim Jagielski]
12395 *) Updated helpers/GuessOS for ...
12396 SCO 5 (recognize minor releases)
12397 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
12398 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
12399 IRIX64 (-sgi-irix64)
12400 ULTRIX (-unknown-ultrix)
12401 SINIX (-whatever-sysv4)
12402 NCR Unix (-ncr-sysv4)
12403 and fixed something in helpers/PrintPath [Ben Laurie]
12405 Changes with Apache 1.2b1
12407 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
12409 Changes with Apache 1.1.1
12411 *) Fixed bug where Cookie module would make two entries in the
12412 logfile for each access [Mark Cox]
12414 *) Fixed bug where Redirect in .htaccess files would cause memory
12415 leak. [Nathan Neulinger]
12417 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
12419 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
12421 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
12423 Changes with Apache 1.1.0
12425 *) Bring NeXT support up to date. [Takaaki Matsumoto]
12427 *) Bring QNX support up to date. [Ben Laurie]
12429 *) Make virtual hosts default to main server keepalive parameters.
12430 [Alexei Kosut, Ben Laurie]
12432 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
12434 *) Fix missing address family for connect, also remove unreachable statement
12435 in mod_proxy. [Ben Laurie]
12437 *) mod_env now turned on by default in Configuration.tmpl.
12439 *) Bugs which were fixed:
12440 a) yet more mod_proxy bugs [Ben Laurie]
12441 b) CGI works again with inetd [Alexei Kosut]
12442 c) Leading colons were stripped from passwords [<osm interguide.com>]
12443 d) Another fix to multi-method Limit problem [<jk tools.de>]
12445 Changes with Apache 1.1b4
12447 *) r->bytes_sent variable restored. [Robert Thau]
12449 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
12451 *) More possibly unsecure programs removed from the support directory.
12453 *) More mod_auth_msql authentication improvements.
12455 *) VirtualHosts based on Host: headers no longer conflict with the
12458 *) OS/2 compatibility enhancements. [Gary Smiley]
12460 *) POST now allowed to directory index CGI scripts.
12462 *) Actions now work with files of the default type.
12464 *) Bugs which were fixed:
12465 a) more mod_proxy bugs
12466 b) early termination of inetd requests
12467 c) compile warnings on several systems
12468 d) problems when scripts stop reading output early
12470 Changes with Apache 1.1b3
12472 *) Much of cgi-bin and all of cgi-src has been removed, due to
12473 various security holes found and that we could no longer support
12476 *) The "Set-Cookie" header is now special-cased to not merge multiple
12477 instances, since certain popular browsers can not handle multiple
12478 Set-Cookie instructions in a single header. [Paul Sutton]
12480 *) rprintf() added to buffer code, occurrences of sprintf removed.
12483 *) CONNECT method for proxy module, which means tunneling SSL should work.
12484 (No crypto needed) Also a NoCache config directive.
12486 *) Several API additions: pstrndup(), table_unset() and get_token()
12487 functions now available to modules.
12489 *) mod_imap fixups, in particular Location: headers are now complete
12492 *) New "info" module which reports on installed module set through a
12493 special URL, a la mod_status.
12495 *) "ServerPath" directive added - allows for graceful transition
12496 for Host:-header-based virtual hosts.
12498 *) Anonymous authentication module improvements.
12500 *) MSQL authentication module improvements.
12502 *) Status module design improved - output now table-based. [Ben Laurie]
12504 *) htdigest utility included for use with digest authentication
12507 *) mod_negotiation: Accept values with wildcards to be treated with
12508 less priority than those without wildcards at the same quality
12509 value. [Alexei Kosut]
12511 *) Bugs which were fixed:
12512 a) numerous mod_proxy bugs
12513 b) CGI early-termination bug [Ben Laurie]
12514 c) Keepalives not working with virtual hosts
12515 d) RefererIgnore problems
12516 e) closing fd's twice in mod_include (causing core dumps on
12517 Linux and elsewhere).
12519 Changes with Apache 1.1b2
12522 a) core dumps in mod_digest
12523 b) truncated hostnames/ip address in the logs
12524 c) relative URL's in mod_imap map files
12526 Changes with Apache 1.1b1
12528 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12530 Changes with Apache 1.0.3
12532 *) Internal redirects which occur in mod_dir.c now preserve the
12533 query portion of a request (the bit after the question mark).
12536 *) Escape active characters '<', '>' and '&' in html output in
12537 directory listings, error messages and redirection links.
12540 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12542 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12545 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12547 *) Reset timeout timer after each successful fwrite() to the network.
12548 This patch adds a reset_timeout() procedure that is called by
12549 send_fd() to reset the timeout ever time data is written to the net.
12552 *) timeout() signal handler now checks for SIGPIPE and reports
12553 lost connections in a more user friendly way. [Rob Hartill]
12555 *) Location of the "scoreboard" file which used to live in /tmp is
12556 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12557 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12559 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12561 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12562 which caused a SEGV with cookies enabled
12564 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12567 *) Log the UNIX textual error returned by some system calls, in
12568 particular errors from accept() [David Robinson]
12570 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12572 Changes with Apache 1.0.2
12574 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12575 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12577 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12580 *) past changes to http_config.c to only use the
12581 setrlimit function on systems defining RLIMIT_NOFILE
12582 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12583 for SUNOS and prototypes the needed functions.
12585 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12588 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12590 *) Merge multiple headers from CGI scripts instead of taking last
12591 one. [David Robinson]
12593 *) Add support for SCO 5. [Ben Laurie]
12595 Changes with Apache 1.0.1
12597 *) Silence mod_log_referer and mod_log_agent if not configured
12600 *) Recursive includes can occur if the client supplies PATH_INFO data
12601 and the server provider uses relative links; as file.html
12602 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
12604 *) The replacement for initgroups() did not call {set,end}grent(). This
12605 had two implications: if anything else used getgrent(), then
12606 initgroups() would fail, and it was consuming a file descriptor.
12609 *) On heavily loaded servers it was possible for the scoreboard to get
12610 out of sync with reality, as a result of a race condition.
12611 The observed symptoms are far more Apaches running than should
12612 be, and heavy system loads, generally followed by catastrophic
12613 system failure. [Ben Laurie]
12615 *) Fix typo in license. [David Robinson]
12617 Changes with Apache 1.0.0 23 Nov 1995
12619 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
12621 Changes with Apache 0.8.16 05 Nov 1995
12623 *) New man page for 'httpd' added to support directory [David Robinson]
12625 *) .htgroup files can have more than one line giving members for a
12626 given group (each must have the group name in front), for NCSA
12627 back-compatibility [Robert Thau]
12629 *) Mutual exclusion around accept() is on by default for SVR4 systems
12630 generally, since they generally can't handle multiple processes in
12631 accept() on the same socket. This should cure flaky behavior on
12632 a lot of those systems. [David Robinson]
12634 *) AddType, AddEncoding, and AddLanguage directives take multiple
12635 extensions on a single command line [David Robinson]
12637 *) UserDir can be disabled for a given virtual host by saying
12638 "UserDir disabled" in the <VirtualHost> section --- it was a bug
12639 that this didn't work. [David Robinson]
12641 *) Compiles on QNX [Ben Laurie]
12643 *) Corrected parsing of ctime time format [David Robinson]
12645 *) httpd does a perror() before exiting if it can't log its pid
12646 to the PidFile, to make diagnosing the error a bit easier.
12649 *) <!--#include file="..."--> can no longer include files in the
12650 parent directory, for NCSA back-compatibility. [David Robinson]
12652 *) '~' is *not* escaped in URIs generated for directory listings
12655 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
12657 *) Fixed bug involving handling URIs with escaped %-characters
12658 in redirects [David Robinson]
12660 Changes with Apache 0.8.15 14 Oct 1995
12662 *) Switched to new, simpler license
12664 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
12666 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
12668 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
12670 *) Correctly handles internal redirects to files with names containing '%'
12673 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
12675 *) Use geteuid() rather than getuid() to see if we have root privilege,
12676 so that server correctly resets privilege if run setuid root. [Andrew
12679 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
12682 *) Fix relative URLs in imagemap files [Randy Terbush]
12684 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
12687 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
12688 entries all name the same one. [David Robinson]
12690 *) Fix directory listings with filenames containing unusual characters
12693 *) Better URI-escaping for generated URIs in directories with filenames
12694 containing unusual characters [Ben Laurie]
12696 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
12698 *) Unblock alarms on error return from spawn_child() [David Robinson]
12700 *) Sample Config files have extra note for SCO users [Ben Laurie]
12702 *) Configuration has note for HP-UX users [Rob Hartill]
12704 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
12706 *) Nuked bogus #define in httpd.h [David Robinson]
12708 *) Better test for whether a system has setrlimit() [David Robinson]
12710 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
12712 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
12715 Changes with Apache 0.8.14 19 Sep 1995
12717 *) Compiles on SCO ODT 3.0 [Ben Laurie]
12719 *) AddDescription works (better) [Ben Laurie]
12721 *) Leaves an intelligible error diagnostic when it can't set group
12722 privileges on standalone startup [Andrew Wilson]
12724 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
12725 that machine, which claims to be BSD but does not support RLIMIT.
12728 *) gcc -Wall no longer complains about an unused variable when util.c
12729 is compiled with -DMINIMAL_DNS [Andrew Wilson]
12731 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
12733 Changes with Apache 0.8.13 07 Sep 1995
12735 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
12737 *) Have built-in imagemap code recognize & honor Point directive [James
12740 *) Generate cleaner directory listings in directories with a mix of
12741 long and short filenames [Rob Hartill]
12743 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
12745 *) Properly default ServerName for virtual servers [Robert Thau]
12747 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
12748 Paul Richards and a cast of thousands...]
12750 *) On self-identified BSD systems (we don't try to guess any more),
12751 allocate a few extra file descriptors per virtual host with setrlimit,
12752 if we can, to avoid running out. [Randy Terbush]
12754 *) Write 22-character lock file name into buffer with enough space
12755 on startup [Konstantin Olchanski]
12757 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
12760 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
12762 *) Suppress -Wall warning by initializing variable in negotiation code
12763 [Tobias Weingartner]
12765 Changes with Apache 0.8.12 31 Aug 1995
12767 *) Doesn't pause three seconds after including a CGI script which is
12768 too slow to die off (this is done by not even trying to kill off
12769 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
12770 after the entire document has been processed). [Robert Thau]
12772 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
12774 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
12776 *) Allows .htaccess files to override <Directory> sections naming the
12777 same directory [David Robinson]
12779 *) Removed an efficiency hack in sub_req_lookup_uri which was
12780 causing certain extremely marginal cases (e.g., ScriptAlias of a
12781 *particular* index.html file) to fail. [David Robinson]
12783 *) Doesn't log an error when the requested URI requires
12784 authentication, but no auth header line was supplied by the
12785 client; this is a normal condition (the client doesn't no auth is
12786 needed here yet). [Robert Thau]
12788 *) Behaves more sanely when the name server loses its mind [Sean Welch]
12790 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
12792 *) RFC931 code no longer passes out name of prior clients on current
12793 requests if the current request came from a server that doesn't
12794 do RFC931. [David Robinson]
12796 *) Configuration script accepts "Module" lines with trailing whitespace.
12799 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
12801 *) Cleaned up comments in mod_cgi.c [Robert Thau]
12803 Changes with Apache 0.8.11 24 Aug 1995
12805 *) Wildcard <Directory> specifications work. [Robert Thau]
12807 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
12809 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
12810 the file being requested itself, in addition to the directories leading
12811 up to it. [Robert Thau]
12813 *) Logs access failures due to symlink checks or invalid client address
12814 in the error log [Roy Fielding, Robert Thau]
12816 *) Symlink checks deal correctly with systems where lstat of
12817 "/path/to/some/link/" follows the link. [Thau, Fielding]
12819 *) Doesn't reset DirectoryIndex to 'index.html' when
12820 other directory options are set in a .htaccess file. [Robert Thau]
12822 *) Clarified init code and nuked bogus warning in mod_access.c
12823 [Florent Guillaume]
12825 *) Corrected several directives in sample srm.conf
12826 --- includes corrections to directory indexing icon-related directives
12827 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
12828 icons for encodings right, and turning on AddEncoding by default).
12831 *) Corrected descriptions of args to AddIcon and AddAlt in command table
12834 *) INSTALL & README mention "contributed modules" directory [Brian
12837 *) Fixed English in the license language... "for for" --> "for".
12840 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
12841 mod_alias.c, merging it almost completely with handling of Alias, and
12842 adding a 'notes' field to the request_rec which allows the CGI module
12843 to discover whether the Alias module has put this request through
12844 ScriptAlias (which it needs to know for back-compatibility, as the old
12845 NCSA code did not check Options ExecCGI in ScriptAlias directories).
12848 Changes with Apache 0.8.10 18 Aug 1995
12850 *) AllowOverride applies to the named directory, and not just
12851 subdirectories. [David Robinson]
12853 *) Do locking for accept() exclusion (on systems that need it)
12854 using a special file created for the purpose in /usr/tmp, and
12855 not the error log; using the error log causes real problems
12856 if it's NFS-mounted; this is known to be the cause of a whole
12857 lot of "server hang" problems with Solaris. [David Robinson;
12858 thanks to Merten Schumann for help diagnosing the problem].
12860 Changes with Apache 0.8.9 12 Aug 1995
12862 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
12864 *) Nested includes see environment variables of the including document,
12865 for NCSA bug-compatibility (some sites have standard footer includes
12866 which try to print out the last-modified date). [Eric Hagberg/Robert
12869 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
12870 URI as a CGI script, even if it would have been treated as something
12871 else if requested directly, for NCSA back-compatibility. (Note that
12872 this means that people who know the name of the script can see the
12873 code just by asking for it). [Robert Thau]
12875 *) New version of dbmmanage script included in support directory as
12878 *) Check if scoreboard file couldn't be opened, and say so, rather
12879 then going insane [David Robinson]
12881 *) POST to CGI works on A/UX [Jim Jagielski]
12883 *) AddIcon and AddAlt commands work properly [Rob Hartill]
12885 *) NCSA server push works properly --- the Arena bug compatibility
12886 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
12887 if you still want the workaround). [Rob Hartill]
12889 *) If client didn't submit any Accept-encodings, ignore encodings in
12890 content negotiation. (NB this will all have to be reworked anyway
12891 for the new HTTP draft). [Florent Guillaume]
12893 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
12895 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
12897 *) Give Redirect priority over Alias, for NCSA bug compatibility
12900 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
12901 paralleling earlier bug fix for CGI [David Robinson]
12903 *) If DBM auth is improperly configured, report a server error and don't
12906 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
12907 it seems to work well enough without it (even in a 10 hits/sec
12908 workout), and the overhead for the locking under A/UX is
12909 alarmingly high (though it is very low on other systems).
12910 [Eric Hagberg, Jim Jagielski]
12912 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
12914 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
12915 Behlendorf/Eric Hagberg]
12917 *) More improvements to default Configuration for A/UX [Jim Jagielski]
12919 *) Compiles clean on NEXT [Rob Hartill]
12921 *) Compiles clean on SGI [Robert Thau]
12923 Changes with Apache 0.8.8 08 Aug 1995
12925 *) SunOS library prototypes now never included unless explicitly
12926 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
12927 people using GNU libc on SunOS are screwed by prototypes for the
12930 (Those who wish to compile clean with gcc -Wall on a standard
12931 SunOS setup need the prototypes, and may obtain them using
12932 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
12933 with nonstandard libraries are presumably competent to make their
12936 *) Strips trailing '/' characters off both args to the Alias command,
12937 to make 'Alias /foo/ /bar/' work.
12939 Changes with Apache 0.8.7 03 Aug 1995
12941 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
12942 [reported by David Robinson]
12944 *) Compiles clean on OSF/1 [David Robinson]
12946 *) Added some of the more recent significant changes (AddLanguage stuff,
12947 experimental LogFormat support) to CHANGES file in distribution root
12950 Changes with Apache 0.8.6 02 Aug 1995
12952 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
12953 (If you actually wanted a conditional GET which bypassed the cache, you
12954 couldn't get it). [Reported by Roy Fielding]
12956 *) Properly terminate headers on '304 Not Modified' replies to conditional
12957 GETs --- no browser we can find cares much, but the CERN proxy chokes.
12958 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
12960 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
12962 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
12963 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
12964 and older versions don't set the __SUNPRO_C preprocessor variable). On
12965 all other systems, these are never used anyway. [Reported by Mark Cox].
12967 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
12969 Changes with Apache 0.8.5 01 Aug 1995
12971 *) Added last-minute configurable log experiment, as optional module
12973 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
12974 properly. (One-line fix to http_protocol.c).
12976 *) Work around bogus behavior when reloading from Netscape.
12977 It's Netscape's bug --- for some reason they expect a request with
12978 If-modified-since: to not function as a conditional GET if it also
12979 comes with Pragma: no-cache, which is way out of line with the HTTP
12980 spec (according to Roy Fielding, the redactor).
12982 *) Added parameter to set maximum number of server processes.
12984 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
12987 *) IdentityCheck bugfix [Chuck Murcko].
12989 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
12991 *) More sample config file corrections; add extension to AddType for
12992 *.asis, move AddType generic description to its proper place, and
12993 fix miscellaneous typos. [ Alexei Kosut ]
12995 *) Deleted the *other* reference to the regents from the Berkeley
12996 legal disclaimer (everyplace).
12998 *) Nuked Shambhala name from src/README; had already cleaned it out
12999 of everywhere else.
13001 Changes with Apache 0.8.4
13003 *) Changes to server-pool management parms --- renamed current
13004 StartServers to MinSpareServers, created separate StartServers
13005 parameter which means what it says, and renamed MaxServers to
13006 MaxSpareServers (though the old name still works, for NCSA 1.4
13007 back-compatibility). The old names were generally regarded as
13008 too confusing. Also altered "docs" in sample config files.
13010 *) More improvements to default config files ---
13011 sample directives (commented out) for XBitHack, BindAddress,
13012 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
13013 defaults, AddTypes for send-as-is and imagemap magic types, and
13014 improvements to samples for DirectoryIndex [Alexei Kosut]
13016 *) Yet more improvements to default config files --- changes to
13017 Alexei's sample AddLanguage directives, and sample LanguagePriority
13018 [ Florent Guillaume ]
13020 *) Set config file locations properly if not set in httpd.conf
13023 *) Don't escape URIs in internal redirects multiple times; don't
13024 do that when translating PATH_INFO to PATH_TRANSLATED either.
13027 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
13029 Changes with Apache 0.8.3
13031 *) Edited distribution README to *briefly* summarize installation
13032 procedures, and give a pointer to the INSTALL file in the src/
13035 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
13036 recent NCSA distributions.
13038 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
13039 exist for the same directory, use both and don't segfault. [Reported
13042 *) Proper makefile dependencies [David Robinson]
13044 *) Note (re)starts in error log --- reported by Rob Hartill.
13046 *) Only call no2slash() after get_path_info() has been done, to
13047 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
13048 reported by Andrew Wilson, though this one is probably a real bug]
13050 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
13051 dump core when Referer is not supplied. [Randy Terbush]
13053 *) Lightly edited sample config files to refer people to our documentation
13054 instead of NCSA's, and to list Rob McCool as *original* author (also
13055 deleted his old, and no doubt non-functional email address). Would be
13056 nice to have examples of new features...
13058 Changes with Apache 0.8.2 19 Jul 1995
13060 *) Added AddLanuage code [Florent Guillaume]
13062 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
13064 *) All sorts of problems when MultiViews finds a directory. It would
13065 be nice if mod_dir.c was robust enough to handle that, but for now,
13066 just punt. [reported by Brian Behlendorf]
13068 *) Wait for all children on restart, to make sure that the old socket
13069 is gone and we can reopen it. [reported by Randy Terbush]
13071 *) Imagemap module is enabled in default Configuration
13073 *) RefererLog and UserAgentLog modules properly default the logfile
13076 *) Mark Cox's mod_cookies added to the distribution as an optional
13077 module (commented out in the default Configuration, and noted as
13078 an experiment, along with mod_dld). [Mark Cox]
13080 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
13082 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
13084 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
13086 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
13089 Changes with Apache 0.8.1
13091 *) New imagemap module [Randy Terbush]
13093 *) Replacement referer log module with NCSA-compatible RefererIgnore
13094 [Matthew Gray again]
13096 *) Don't mung directory listings with very long filenames.
13097 [Florent Guillaume]
13099 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
13101 *) New config script. See INSTALL for info. [Robert Thau]
13103 *) Scoreboard mechanism for regulating the number of extant server
13104 processes. MaxServers and StartServers defaults are the same as
13105 for NCSA, but the meanings are slightly different. (Actually,
13106 I should probably lower the MaxServers default to 10).
13108 Before asking for a new connection, each server process checks
13109 the number of other servers which are also waiting for a
13110 connection. If there are more than MaxServers, it quietly dies
13111 off. Conversely, every second, the root, or caretaker, process
13112 looks to see how many servers are waiting for a new connection;
13113 if there are fewer than StartServers, it starts a new one. This
13114 does not depend on the number of server processes already extant.
13115 The accounting is arranged through a "scoreboard" file, named
13116 /tmp/htstatus.*, on which each process has an independent file
13117 descriptor (they need to seek without interference).
13119 The end effect is that MaxServers is the maximum number of
13120 servers on an *inactive* server machine, but more will be forked
13121 off to handle unusually heavy loads (or unusually slow clients);
13122 these will die off when they are no longer needed --- without
13123 reverting to the overhead of full forking operation. There is a
13124 hard maximum of 150 server processes compiled in, largely to
13125 avoid forking out of control and dragging the machine down.
13126 (This is arguably too high).
13128 In my server endurance tests, this mechanism did not appear to
13129 impose any significant overhead, even after I forced it to put the
13130 scoreboard file on a normal filesystem (which might have more
13131 overhead than tmpfs). [Robert Thau]
13133 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
13136 *) Read .htaccess files even in directory with <Directory> section.
13137 (Former incompatibility noted on mailing list, now fixed). [Robert
13140 *) "HEAD /" gives the client a "Bad Request" error message, rather
13141 than trying to send no body *and* no headers. [Cliff Skolnick].
13143 *) Don't produce double error reports for some very obscure cases
13144 mainly involving auth configuration (the "all modules decline to
13145 handle" case which is a sure sign of a server bug in most cases,
13146 but also happens when authentication is badly misconfigured).
13149 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
13150 it's *for*, and this sort of thing really shouldn't be cluttering
13151 up the Makefile). [Robert Thau]
13153 *) Incidental code cleanups in http_main.c --- stop dragging
13154 sa_client around; just declare it where used. [Robert Thau]
13156 *) Another acc-related fix. (It doesn't like const char
13157 in some places...). [Mark Cox]
13159 Changes with Shambhala 0.6.1 13 Jul 1995
13161 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
13162 Also, fixed auth typo in http_protocol.c unmasked by this fix.
13164 *) Compiles clean with acc on SunOS [Paul Sutton]
13166 *) Reordered modules in modules.c so that Redirect takes priority
13167 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
13168 believe it or not, he has an actual site with a ScriptAlias and
13169 a Redirect declared for the *exact same directory*. Even *my*
13170 compatibility fetish wouldn't motivate me to fix this if the fix
13171 required any effort, but it doesn't, so what the hey.
13173 *) Fixed to properly default several server_rec fields for virtual
13174 servers from the corresponding fields in the main server_rec.
13175 [Cliff Skolnick --- 'port' was a particular irritant].
13177 *) No longer kills off nph- child processes before they are
13178 finished sending output. [Matthew Gray]
13180 Changes with Shambhala 0.6.0 10 Jul 1995
13182 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
13183 the connection to the client in an "aborted" state, but otherwise
13184 allow whatever handlers are running to clean up. hard_timeout()s
13185 abort the request in progress completely; anything not tied to some
13186 resource pool cleanup will leak. They're still around because I
13187 haven't yet come up with a more elegant way of handling
13188 timeouts when talking to something that isn't the client. The
13189 default_handler and the dir_handler now use soft timeouts, largely
13190 so I can test the feature. [Robert Thau]
13192 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
13193 the case of log handlers dying prematurely is probably handled VERY
13194 gracelessly at this point, and if the logger stops reading input,
13195 the server will hang. (It is known to correctly restart the
13196 logging process on server restart; this is (should be!) going through
13197 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
13198 script). [Robert Thau]
13200 *) asis files supported (new module). [Robert Thau]
13202 *) IdentityCheck code is compiled in, but has not been tested. (I
13203 don't know anyone who runs identd). [Robert Thau]
13205 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
13206 came in with the request, for NCSA bug-compatibility. [Robert Thau]
13208 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
13210 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
13211 as timeouts are not in scope. [Robert Thau]
13213 *) quoted-string args in config files now handled correctly (doesn't drop
13214 the last character). [Robert Thau; reported by Randy Terbush]
13216 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
13217 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
13219 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
13220 default default type); the former default default behavior when all
13221 type-checkers defaulted had been a core dump. [Paul Sutton]
13223 *) Copy filenames out of the struct dirent when indexing
13224 directories. (On Linux, readdir() returns a pointer to the same
13225 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
13227 Changes with Shambhala 0.5.3 [not released]
13229 *) Default response handler notes "file not found" in the error log,
13230 if the file was not found. [Cliff Skolnick].
13232 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
13233 code no longer sets up bogus PATH_INFO which fakes out the directory
13234 handler). [Cliff Skolnick]
13236 Changes with Shambhala 0.5.2 06 Jul 1995
13238 *) Changes to http_main.c --- root server no longer plays silly
13239 games with SIGCHLD, and so now detects and replaces dying
13240 children. Child processes just die on SIGTERM, without taking
13241 the whole process group with them. Potential problem --- if any
13242 child process refuses to die, we hang in restart.
13243 MaxRequestsPerChild may still not work, but it certainly works
13244 better than it did before this! [Robert Thau]
13246 *) mod_dir.c bug fixes: ReadmeName and HeaderName
13247 work (or work better, at least); over-long description lines
13248 properly terminated. [Mark Cox]
13250 *) http_request.c now calls unescape_url() more places where it
13251 should [Paul Sutton].
13253 *) More directory handling bugs (reported by Cox)
13254 Parent Directory link is now set correctly. [Robert Thau]
13256 Changes with Shambhala 0.5.1 04 Jul 1995
13258 *) Generalized cleanup interface in alloc.c --- any function can be
13259 registered with alloc.c as a cleanup for a resource pool;
13260 tracking of files and file descriptors has been reimplemented in
13261 terms of this interface, so I can give it some sort of a test.
13264 *) More changes in alloc.c --- new cleanup_for_exec() function,
13265 which tracks down and closes all file descriptors which have been
13266 registered with the alloc.c machinery before the server exec()s a
13267 child process for CGI or <!--#exec-->. CGI children now get
13268 started with exactly three file descriptors open. Hopefully,
13269 this cures the problem Rob H. was having with overly persistent
13270 CGI connections. [Robert Thau]
13272 *) Mutual exclusion around the accept() in child_main() --- this is
13273 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
13274 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
13275 This uses fcntl(F_SETLK,...) on the error log descriptor because
13276 flock() on that descriptor won't work on systems which have BSD
13277 flock() semantics, including (I think) Linux 1.3 and Solaris.
13279 This does work on SunOS (when the server is idle, only one
13280 process in the pool is waiting on accept()); it *ought* to work
13281 on the other systems. [Robert Thau]
13283 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
13285 *) sizeof(*sa_client) bugfix from [Rob Hartill]
13287 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
13289 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
13290 be unnecessary if I go to the revised timeout-handling scheme).
13293 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
13294 string) even if none came in with the request. [Robert Thau]
13296 *) CHANGES file added to distribution ;-).
13298 Changes with Shambhala 0.4.5
13300 *) mod_dld --- early dynamic loading support [rst]
13301 *) Add wildcard content handlers for XBITHACK; default_hander now
13302 invoked with that mechanism (as a handler hanging off mod_core) [rst]
13303 *) XBITHACK supported as a wildcard content-handler, and
13304 configurable at run-time (not just at compile time, as in the
13305 "patchy server" releases) [rst]
13307 Changes with Shambhala 0.4.4 30 Jun 1995
13309 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
13310 *) Handle Addtype x/y .z [rst, reported by Cox]
13312 Changes with Shambhala 0.4.3
13314 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
13315 synonymous [rst, terbush]
13317 Changes with Shambhala 0.4.1 28 Jun 1995
13319 *) First-cut virtual host implementation; some refit in the config
13320 reading code, and log management, was necessary to support this [rst]
13321 *) Sub-pool machinery, originally added to avoid excessive storage
13322 allocation on listings of large directories (which turned out to
13323 be the problem that the 0.3 storage accounting was added to
13324 find). Subrequests and mod_dir changed to use subpools. [rst]
13325 *) More memory debugging --- free list consistency checks. [rst]
13326 *) Added err_headers to request_rec, with support elsewhere [rst]
13327 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
13329 Changes with Shambhala 0.3 19 Jun 1995
13331 *) Switch ONE_PROCESS to a runtime command-line option (-X)
13332 *) Don't compile in mod_ai_backcompat by default
13333 *) Switch name of server from Apache to Shambhala in Makefile
13334 *) Add some accounting routines to track memory usage in the pools,
13337 Changes with Shambhala 0.2
13339 *) Set DOCUMENT_ROOT CGI variable
13340 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
13341 *) Add critical section protection to handling of cleanup structures
13343 *) Significant code reorg within the server core to group related
13344 functions together [rst]
13345 *) Correctly handle clients that hang up before sending any request
13347 *) Replace dying child processes. [rst]
13349 Changes with Shambhala 0.1 12 Jun 1995
13351 Major rewrite of the pre-existing "patchy server" codebase, by
13352 Robert Thau (rst). Significant portions of the server code, such
13353 as configuration-file handling and HTTP authentication support,
13354 were ripped out and rewritten from scratch. Code that was not
13355 completely rewritten was significantly altered.
13357 Major changes with this release include:
13359 *) Introduction of the module API; in request handling, the central
13360 machinery just dispatches to various modules, which actually do
13361 most of the work. Configuration handling is similar --- modules
13362 declare their own commands, and the central machinery just
13363 dispatches to them.
13365 API features from shambhala/0.1 were substantially unchanged in
13366 Apache 1.0 and 1.1. (1.0 API features not yet present in this
13367 release, such as wildcard handlers and subpools, were added in
13368 subsequent Shambhala releases, and were also generally rst's
13371 *) This release included the following modules:
13373 mod_access (access control --- allow and deny directives),
13374 mod_alias (Alias and Redirect commands),
13375 mod_auth (straight HTTP authentication, based on flat-files)
13376 mod_auth_dbm (same, with dbm files)
13377 mod_cgi (CGI scripts and, in this release, ScriptAlias)
13378 mod_common_log (CLF access logs; later renamed mod_log_common)
13379 mod_dir (directory indexing)
13380 mod_include (server-side includes)
13381 mod_mime (AddType directives)
13382 mod_negotiation (content negotiation)
13383 mod_userdir (support for users' public_html directories)
13385 It also included a mod_ai_backcompat, which was a private hack
13386 for back-compatibility with rst's own AI-lab servers.
13388 All of these modules were substantially complete, and functional
13389 or nearly so (a few, which implemented features not in use at
13390 Thau's site, required patches of a few lines).
13392 *) sub-request machinery, to allow modules to determine how other
13393 modules would assign MIME types to a given file, or optionally
13394 serve its content (this is heavily used by mod_dir, mod_include
13395 and mod_negotiation).
13397 *) Resource pool system for keeping track of memory allocated and
13398 files opened in service of a particular request. Much of the
13399 code in the modules (when they weren't rewrites) was adjusted to
13400 replace a pervasive convention of using fixed-size buffers on
13401 the stack with an equally pervasive convention of using memory
13402 allocated with palloc().
13404 *) Reorganization of data structures associated with a given
13405 request to eliminate use of global variables and the troublesome
13406 unmunge_name function (used in NCSA and early Apache releases to
13407 attempt to determine the URI which mapped to a given filename
13408 --- a difficult proposition, given that it is easy to produce
13409 setups in which multiple URIs map to the same file).
13411 *) Source files renamed and rearranged
13413 *) Very simple pre-forking behavior --- parent process forked off a
13414 fixed number of children, and then just waited for SIGHUP.
13416 *) Other more minor changes too numerous to list.
13418 This release included modified versions of a lot of code from the
13419 Apache 0.6.4 public release, plus an early pre-forking patch
13420 codeveloped by Robert Thau and Rob Hartill.
13422 Changes with Apache 0.7.3 20 Jun 1995
13424 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
13425 were incorporated by Rob Hartill on the main branch while Robert Thau
13426 worked on the Shambhala rewrite above. Most were merged into the
13427 Shambala architecture after Apache 0.8.0.
13429 Changes with Apache 0.6.4 13 May 1995
13431 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
13434 Changes with Apache 0.5.1 10 Apr 1995
13436 Changes with Apache 0.4 02 Apr 1995
13438 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
13441 Changes with Apache 0.3 24 Mar 1995
13443 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
13446 Changes with Apache 0.2 18 Mar 1995
13448 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
13449 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
13450 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
