39 *) Make REMOTE_PORT variable available in mod_rewrite.
40 PR 25772. [André Malo]
42 *) proxy_http fix: mod_proxy hangs when both KeepAlive and
43 ProxyErrorOverride are enabled, and a non-200 response without a
44 body is generated by the backend server. (e.g.: a client makes a
45 request containing the "If-Modified-Since" and "If-None-Match"
46 headers, to which the backend server respond with status 304.)
47 [Graham Wiseman <gwiseman fscinternet.com>, Richard Reiner]

64 PR: 22951 [Ermanno Scaglione scaglione ..at.. starnetone.de]
66 *) Bring ErrorHeader concept forward from 1.3, so that response
67 header fields can be set for return even on errors or external

71 failed" messages during restart and problem with the logger
72 respawning again after Apache is stopped. PR 21648, PR 24805.
75 *) Fix <Limit> and <LimitExcept> parsing to require a closing '>'
76 in the initial container. PR 25414.
77 [Geoffrey Young <geoff apache.org>]

80 directory, display the MPM name and some MPM properties.
81 [Geoffrey Young <geoff apache.org>]
83 *) Fixed cache-removal order in mod_mem_cache.
84 [Jean-Jacques Clar, Cliff Woolley]

109 treated the supplied regex as literal string. PR 24219.
112 *) Log an error when requests for URIs which fail to map to a valid
113 filesystem name are rejected with 403. [Jeff Trawick]
115 *) Switch to APR 1.0 API.
117 *) Fix mod_include's expression parser to recognize strings correctly
118 even if they start with an escaped token. [André Malo]
120 *) Major overhaul of mod_include's filter parser. The new parser code
121 is expected to be more robust and should catch all of the edge cases
122 that were not handled by the previous one. This includes a binary
123 incompatible change of mod_include's external API. [André Malo]
125 *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
126 PR 14223. [André Malo]

129 could lead to a 400 (Bad Request) response. [André Malo]
131 *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously
132 the current rewrite state was just used as lookup path, which lead to
133 strange and often useless results. Related to PR 8493. [André Malo]
135 *) Change Listen directive to bind to all addresses when a hostname is
136 not specified. [Justin Erenkrantz]
138 *) Correct failure with Listen directives on machines with IPv6 enabled.
139 [Colm MacCárthaigh <colm stdlib.net>, Justin Erenkrantz]
141 *) Fix a link failure in mod_ssl when the OpenSSL libraries contain
142 the ENGINE functions but the engine header files are missing.
145 *) mod_rewrite: RewriteRules in server context using the force
146 type feature [T=...] no longer disable MultiViews. [André Malo]
148 *) mod_rewrite: Allow piped rewrite logs to be relative to ServerRoot.
151 *) mod_authz_groupfile: Strip trailing spaces of group names. This
152 hopefully saves some hours of searching for typos. PR 12863.
155 *) mod_actions: Propagate the handler name to the action script via
156 the REDIRECT_HANDLER environment variable. [André Malo]
158 *) mod_actions: Introduce the "virtual" modifier to the Action directive,
159 which allows the use of handlers for virtual locations. PR 8431.
162 *) mod_speling: Recognize AcceptPathInfo setting for the particular
163 location. Default is to reject path information. PR 21059.
166 *) mod_ext_filter: Add the ability to filter request bodies.

181 *) Fix a compile failure with recent OpenSSL and picky compilers
182 (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
184 *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
185 the INCLUDE path to be defined properly.
186 PR 11310. [Geoff Thorpe <geoff geoffthorpe.net>]
188 *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
190 *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
191 autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc).
192 [Geoff Thorpe <geoff geoffthorpe.net>]
194 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
195 [Ian Holsman, André Malo]
197 *) mod_negotiation: quality values are now parsed independent from
198 the current locale. level values are now really parsed as integers.
199 PR 17564. [André Malo]
201 *) Added the WindowsSocketsWorkaround directive for Windows NT/2000/XP
202 to work around problems with certain VPN and Firewall products that
203 have buggy AcceptEx implementations.
204 [Allan Edwards w/ suggestions from Bill Stoddard & Bill Rowe]
206 *) Extend mod_negotiation to evaluate the environment variables
207 no-gzip and gzip-only-text/html the same way as mod_deflate does.
210 *) mod_rewrite: Fix some problems reporting errors with mapping
211 programs (RewriteMap prg:/something). [Jeff Trawick]

229 matched value. [André Malo]
231 *) mod_log_config change optional hook to return previous handler
234 *) Forward port of mod_actions' ability to handle arbitrary methods
235 with the Script directive. [André Malo]
237 *) Let suexec send a message to stderr, if it failed or its policy
238 was violated. This message appears in the error log and allows
239 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]

264 apxs -i -a will add an un-commented AddModule directive for
265 the new module, which breaks the config.
266 PR: 11212 [Joe Orton]
268 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
270 *) Move the check of the Expect request header field after the hook
271 for ap_post_read_request, since that is the only opportunity for
272 modules to handle Expect extensions. [Justin Erenkrantz]

305 The new parser code is expected to be more robust and should
306 catch all of the edge cases that were not handled by the previous one.
307 The 2.1 external API changes were hidden by a wrapper which is
308 expected to keep the API backwards compatible. [André Malo]
310 *) Add a hook (insert_error_filter) to allow filters to re-insert
311 themselves during processing of error responses. Enable mod_expires
312 to use the new hook to include Expires headers in valid error
313 responses. This addresses an RFC violation. It fixes PRs 19794,
314 24884, and 25123. [Paul J. Reder]
316 *) Add Polish translation of error messages. PR 25101.
317 [Tomasz Kepczynski <tomek jot23.org>]

340 *) Fix slow graceful restarts with prefork MPM. [Joe Orton]
342 *) Fix a problem with namespace mappings being dropped in mod_dav_fs;
343 if any property values were set which defined namespaces these
344 came out mangled in the PROPFIND response. PR 11637.
345 [Amit Athavale <amit_athavale persistent.co.in>]
347 *) mod_dav: Return a WWW-auth header for MOVE/COPY requests where

369 fixed a number of other cache code bugs related to PR 15852.
370 Includes a patch submitted by Sushma Rai <rsushma novell.com>.
371 This fixes mod_mem_cache but not mod_disk_cache yet so I'm not
372 closing the PR since that is what they are using. [Paul J. Reder]
374 *) complain via error_log when mod_include's INCLUDES filter is
375 enabled, but the relevant Options flag allowing the filter to run
376 for the specific resource wasn't set, so that the filter won't
377 silently get skipped. next remove itself, so the warning will be
378 logged only once [Stas Bekman, Jeff Trawick, Bill Rowe]

398 *) mod_ssl: Use human-readable OpenSSL error strings in logs; use
399 thread-safe interface for retrieving error strings. [Joe Orton]
401 *) mod_expires: Initialize ExpiresDefault to NULL instead of "" to
402 avoid reporting an Internal Server error if it is used without
403 having been set in the httpd.conf file. PR: 23748, 24459
404 [Andre Malo, Liam Quinn <liam htmlhelp.com>]

438 set, for example, when processing some error conditions.
439 PR 23836. [Brian Akins <bakins web.turner.com>, André Malo]
441 *) fix the config parser to support <Foo>..</Foo> containers (no
442 arguments in the opening tag) supported by httpd 1.3. Without

582 the ServerTokens directive. [Jeff Trawick]
584 Changes with Apache 2.0.47
586 *) SECURITY [CAN-2003-0192]: Fixed a bug whereby certain sequences
587 of per-directory renegotiations and the SSLCipherSuite directive

1142 especially on threaded servers. [Greg Ames, Jeff Trawick]
1144 *) Fix a bug in which mod_proxy sent an invalid Content-Length
1145 when a proxied URL was invoked as a server-side include within
1146 a page generated in response to a form POST. [Brian Pane]
1148 *) Added code to process min and max file size directives and to
1149 init the expirychk flag in mod_disk_cache. Added a clarifying
1150 comment to cache_util. [Paul J. Reder]
1152 *) The value emitted by ServerSignature now mimics the Server HTTP
1153 header as controlled by ServerTokens. [Francis Daly <deva daoine.org>]
1155 *) Gracefully handly retry situations in the SSL input filter,
1156 by following the SSL libraries' retry semantics.
1159 *) Terminate CGI scripts when the client connection drops. This
1160 fix only applies to some normal paths in mod_cgi. mod_cgid
1161 is still busted. PR 8388 [Jeff Trawick]
1163 *) Fix a bug where 416 "Range not satisfiable" was being
1164 returned for content that should have been redirected.

1170 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>].
1172 *) mod_ssl uses free() inappropriately in several places, to free
1173 memory which has been previously allocated inside OpenSSL.
1174 Such memory should be freed with OPENSSL_free(), not with free().

1178 *) Emit a message to the error log when we return 404 because
1179 the URI contained '%2f'. (This was previously nastily silent
1180 and difficult to debug.) [Ken Coar]
1182 *) Fix streaming output from an nph- CGI script. CGI:IRC now
1183 works. PR 8482 [Jeff Trawick]
1185 *) More accurate logging of bytes sent in mod_logio when
1186 the client terminates the connection before the response
1187 is completely sent [Bojan Smojver <bojan rexursive.com>]
1189 *) Fix some problems in the perchild MPM.
1190 [Jonas Eriksson <jonas webkonsulterna.com>]
1192 *) Change the CacheRoot processing to check for a required
1193 value at config time. This saves a lot of wasted processing
1194 if the mod_disk_cache module is loaded but no CacheRoot
1195 was provided. This fix also adds code to log an error
1196 and avoid useless pallocs and procesing when the computed
1197 cache file name cannot be opened. This also updates the
1198 docs accordingly. [Paul J. Reder]
1200 *) Introduce the EnableSendfile directive, allowing users of NFS
1201 shares to disable sendfile mechanics when they either fail
1202 outright or provide intermitantly corrupted data. PR
1205 *) Resolve the error "An operation was attempted on something
1206 that is not a socket. : winnt_accept: AcceptEx failed.

1208 anti-virus software on Windows. PR 8325 [William Rowe]
1210 *) Add the ProxyBadHeader directive, which gives the admin some
1211 control on how mod_proxy should handle bogus HTTP headers from
1212 proxied servers. This allows 2.0 to "emulate" 1.3's behavior if
1213 desired. [Jim Jagielski]
1215 *) Change the LDAP modules to export their symbols correctly
1216 during a Windows build. Add dsp files for Windows. Update
1217 README.ldap file for Windows build instructions.

1236 Changes with Apache 2.0.43
1238 *) SECURITY [CAN-2002-0840]: HTML-escape the address produced by
1239 ap_server_signature() against this cross-site scripting
1240 vulnerability exposed by the directive 'UseCanonicalName Off'.
1241 Also HTML-escape the SERVER_NAME environment variable for CGI
1242 and SSI requests. It's safe to escape as only the '<', '>',
1243 and '&' characters are affected, which won't appear in a valid
1244 hostname. Reported by Matthew Murphy <mattmurphy kc.rr.com>.
1247 *) Fix a core dump in mod_cache when it attemtped to store uncopyable
1248 buckets. This happened, for instance, when a file to be cached
1249 contained SSI tags to execute a CGI script (passed as a pipe
1250 bucket). [Paul J. Reder]
1252 *) Ensure that output already available is flushed to the network
1253 when the content-length filter realizes that no new output will
1254 be available for a while. This helps some streaming CGIs as
1255 well as some other dynamically-generated content. [Jeff Trawick]

1267 this feature. [Jay Ball <jay veggiespam.com>]
1269 *) New Module: mod_logio. adds the ability to log bytes sent and

1287 *) Make mod_cache's CacheMaxStreamingBuffer directive work
1288 properly for virtual hosts that override server-wide mod_cache
1289 setttings. [Matthieu Estrade <estrade-m ifrance.com>]
1291 *) Add -p option to apxs to allow programs to be compiled with apxs.

1315 [Joe Orton <jorton redhat.com>]
1317 *) mod_cache: cache_storage.c. Add the hostname and any request
1318 args to the key generated for caching. This provides a unique
1319 key for each virtual host and for each request with unique
1320 args. [Paul J. Reder, args code provided by Kris Verbeeck]
1322 *) mod_cache: Do not cache responses to GET requests with query

1365 *) The content-length filter no longer tries to buffer up
1366 the entire output of a long-running request before sending
1367 anything to the client. [Brian Pane]
1369 *) Win32: Lower the default stack size from 1MB to 256K. This will
1370 allow around 8000 threads to be started per child process.
1371 'EDITBIN /STACK:size apache.exe' can be used to change this
1372 value directly in the apache.exe executable.
1375 *) Win32: Implement ThreadLimit directive in the Windows MPM.
1378 *) Remove CacheOn config directive since it is set but never checked.
1379 No sense wasting cycles on unused code. Besides, the only truly
1380 bug free code is deleted code. :) [Paul J. Reder]

1400 maps. The dbm type (e.g., ndbm, gdbm) can be specified on the
1401 RewriteMap directive. PR 10644 [Jeff Trawick]

1422 *) mod_disk_cache works much better. This module should still
1423 be considered experimental. [Eric Prud'hommeaux]
1425 *) Performance improvement for keepalive requests: when setting
1426 aside a small file for potential concatenation with the next
1427 response on the connection, set aside the file descriptor rather
1428 than copying the file into the heap. [Brian Pane]
1430 *) Modified version check on openssl so that it finds the executable
1431 first and then performs a check of the version, only warning the
1432 user if they chose, or we selected, an old version of OpenSSL.
1433 This change also allows the code to work for non-openssl libraries
1434 selected via the --with-ssl=dir option, which can override the
1435 automated library check in any case. [Roy Fielding]
1437 Changes with Apache 2.0.40
1439 *) SECURITY [CAN-2002-0661] (cve.mitre.org):
1440 Close a very significant security hole that
1441 applies only to the Win32, OS2 and Netware platforms. Unix was not
1442 affected, Cygwin may be affected. Certain URIs will bypass security
1443 and allow users to invoke or access any file depending on the system
1444 configuration. Without upgrading, a single .conf change will close
1445 the vulnerability. Add the following directive in the global server
1446 httpd.conf context before any other Alias or Redirect directives;
1447 RedirectMatch 400 "\\\.\."
1448 Reported by Auriemma Luigi <bugtest sitoverde.com>.
1451 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1452 Close a path-revealing exposure in multiview type
1453 map negotiation (such as the default error documents) where the
1454 module would report the full path of the typemapped .var file when
1455 multiple documents or no documents could be served based on the mime
1456 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
1459 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1460 Close a path-revealing exposure in cgi/cgid when we

1468 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
1469 will be available for those that wish to work with apr-iconv.
1472 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
1473 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
1475 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
1476 set to 1, so we can exclude things from the general case with
1477 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
1479 *) Accept multiple leading /'s for requests within the DocumentRoot.
1480 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
1482 *) Solved the reports of .pdf byterange failures on Win32 alone.
1483 APR's sendfile for the win32 platform collapses header and trailer
1484 buffers into a single buffer. However, we destroyed the pointers
1485 to the header buffer if a trailer buffer was present. PR 10781
1488 *) mod_ext_filter: Add the ability to enable or disable a filter via
1489 an environment variable. Add the ability to register a filter of
1490 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
1492 *) Restore the ability to specify host names on Listen directives.
1493 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh yahoo.com>]
1495 *) When deciding on the default address family for listening sockets,
1496 make sure we can actually bind to an AF_INET6 socket before
1497 deciding that we should default to AF_INET6. This fixes a startup
1498 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
1500 *) Replace usage of atol() to parse strings when we might want a
1501 larger-than-long value with apr_atoll(), which returns long long.
1502 This allows HTTPD to deal with larger files correctly.
1503 [Shantonu Sen <ssen apple.com>]
1505 *) mod_ext_filter: Ignore any content-type parameters when checking if
1506 the response should be filtered. Previously, "intype=text/html"
1507 wouldn't match something like "text/html;charset=8859_1".
1510 *) mod_ext_filter: Set up environment variables for external programs.
1511 [Craig Sebenik <craig netapp.com>]
1513 *) Modified the HTTP_IN filter to immediately append the EOS (end of
1514 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
1515 the caller to determine that no content remains without prefetching
1516 additional POST body. [William Rowe]

1541 *) APR-Util Renames pending have been completed [Thom May]
1543 *) Performance improvements for the code that reads request
1544 headers (ap_rgetline_core() and related functions) [Brian Pane]
1546 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
1547 to configure the maximum amount of memory the allocators will
1548 hold on to for reuse. Anything over the MaxMemFree threshold
1549 will be free()d. This directive is useful when uncommon large
1550 peaks occur in memory usage. It should _not_ be used to mask
1551 defective modules' memory use. [Sander Striker]
1553 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
1554 scripts would not result in a truncated response.
1555 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
1557 *) Add a filter_init parameter to the filter registration functions
1558 so that a filter can execute arbitrary code before the handlers
1559 are invoked. This resolves a problem where mod_include requests
1560 would incorrectly return a 304. [Justin Erenkrantz]
1562 *) Fix a long-standing bug in 2.0, CGI scripts were being called
1563 with relative paths instead of absolute paths. Apache 1.3 used
1564 absolute paths for everything except for SuExec, this brings back
1565 that standard. [Ryan Bloom]
1567 *) Fix infinite loop due to two HTTP_IN filters being present for
1568 internally redirected requests. PR 10146. [Justin Erenkrantz]
1570 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
1573 *) Fix mod_ext_filter to look in the main server for filter definitions
1574 when running in a vhost if the filter definition is not found in
1575 the vhost. PR 10147 [Jeff Trawick]
1577 *) Support WinNT CGI invocation through ScriptInterpreterSource
1578 'registry' for script interpreter paths and names with non-ascii
1579 characters in the executable filepath. [William Rowe]
1581 *) Support the -w flag on to keep the Win32 console open on error.
1584 *) Normalize the hostname value in the request_rec to all-lowercase
1585 [Perry Harrington <pedward webcom.com>]
1587 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
1588 extended characters (non US-ASCII) in non-utf8 format. This brings
1589 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
1590 to the cgi application itself. [William Rowe]
1592 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
1593 modules to bring them up to the current apr/apr-util APIs.
1596 *) Fix segfault in mod_mem_cache most frequently observed when
1597 serving the same file to multiple clients on an MP machine.
1600 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])

1613 *) Improve ap_get_client_block implementation by using APR-util brigade
1614 helper functions and relying on current filter assumptions.
1617 Changes with Apache 2.0.39

1622 Changes with Apache 2.0.38
1624 *) Rewrite htpasswd to use APR. The removes the annoying warning about
1625 tmpnam being unsafe. [Ryan Bloom]
1627 *) We must set the MIME-type for .shtml files to text/html if we want them
1628 to be parsed for SSI tags. Add the config for that to the default
1629 config file so that it is easier to enable .shtml parsing.
1630 [Dave Dyer <ddyer real-me.net>]
1632 *) Fixed a problem with 'make install' on ReliantUnix.
1633 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
1635 *) Make the default_handler catch all requests that aren't served by
1636 another handler. This also gets us to return a 404 if a directory
1637 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1638 loaded. [Justin Erenkrantz]
1640 *) Fixed the handling of nested if-statements in shtml files.
1641 PR 9866 [Brian Pane]
1643 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1644 into a directory different from the one that was configured. This
1645 also mirrors the root= feature from 1.3. We cannot use prefix=,
1646 because both APR and APR-util resolve their installation paths at
1647 configuration time. This means that there is no variable prefix
1648 to replace. [Andreas Hasenack <andreas netbank.com.br>]
1650 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1651 These levels of AIX don't have a thundering herd problem with
1652 accept(). [Jeff Trawick]
1654 *) prefork MPM: Ignore mutex errors during graceful restart. For
1655 certain types of mutexes (particularly SysV semaphores), we
1656 should expect to occasionally fail to obtain or release the
1657 mutex during restart processing. [Jeff Trawick]
1659 *) Fix install-bindist.sh so that it finds any perl instead of just
1660 early perl 5.x versions. This is consistent with a build/install
1661 from source, and it allows the perl scripts installed by a bindist
1662 to work on systems with perl 5.6. [Jeff Trawick]
1664 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
1665 Tru64 (and probably some other platforms). [Jeff Trawick]
1667 *) Allow CGI scripts to return their Content-Length. This also fixes a
1668 hang on HEAD requests seen on certain platforms (such as FreeBSD).
1671 *) Added log rotation based on file size to the RotateLog support
1672 utility. [Brad Nicholes]

2024 explicitly tell the server that warning messages should be sent
2025 to the client in addition to being recorded in the error log.
2026 Prior to this change, ap_log_rerror() always sent warning
2027 messages to the client. In one case, a faulty CGI script caused
2028 the server to send a warning message to the client that contained
2029 the full path to the CGI script. This could be considered a
2030 minor security exposure. [Bill Stoddard]
2032 *) mod_autoindex output when SuppressRules was specified would

2046 *) Change instdso.sh to use libtool --install everywhere and then
2047 clean up some stray files and symlinks that libtool leaves around
2048 on some platforms. This gets subversion building properly since
2049 it needed a re-link to be performed by libtool at install time,
2050 and the old instdso.sh logic to simply cp the DSO didn't handle
2051 that requirement. [Sander Striker]

2062 *) Fix segfault in mod_mem_cache when garabge collecting an expired
2063 cache entry. [Bill Stoddard]
2065 *) Introduced -E startup_logfile_name option to httpd to allow admins
2066 to begin logging errors immediately. This provides Win32 users
2067 an alternative to sending startup errors to the event viewer, and
2068 allows other daemon tool authors an alternative to logging to stderr.

2157 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
2158 cause the Apache parent process to run in the foreground (similar to
2159 -DNO_DETACH except that it doesn't switch session ids).
2162 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
2163 for those platforms that support it. If using the default
2164 implementation, this is between pthread and sysvsem in priority.
2165 This implies it's the new default for Darwin. [Jim Jagielski]
2167 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
2168 environment variables in the envvars file. [Jeff Trawick]
2170 *) worker MPM: Don't create a listener thread until we have a worker

2253 *) Added exp_foo and rel_foo variables to config_vars.mk for
2254 all Apache and Autoconf path variables (like --sysconfdir,
2255 --sbindir, etc). exp_foo is the "expanded" version, which means
2256 that all internal variable references have been interpolated.
2257 rel_foo is the same as $exp_foo, only relative to $prefix if they
2258 share a common path. [Aaron Bannert]
2260 *) Fix some restart/terminate problems in the worker MPM. Don't

2265 dates. [Graham Leggett]
2267 *) Be more vocal about what AcceptMutex values we allow, to make
2268 us closer to how 1.3 does it. [Jim Jagielski]
2270 *) Get nph- CGI scripts working again. PRs 8902, 8907, 9983
2273 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
2275 *) Add accessor function to set r->content_type. From now on,
2276 ap_rset_content_type() should be used to set r->content_type.
2277 This change is required to properly implement the
2278 AddOutputFilterByType configuration directive.
2279 [Bill Stoddard, Sander Striker, Ryan Bloom]
2281 *) Add new M_FOO symbols for the WebDAV/DeltaV methods specified by
2282 RFC 3253. Improved the method name/number mapping functions.
2285 *) remove sock_enable_linger from connection.c [Ian Holsman]
2287 *) Fix for virtual host processing where the requested hostname
2288 has a '.' at the end (PR 9187) [Ryan Cruse <ryan estara.com>]
2290 *) mod_dav's APIs for REPORT response handling was changed so that
2291 providers can generate the content directly into the output filter
2292 stack, rather than buffering the response into memory. [Greg Stein]
2294 *) Fix a hang condition with graceful restart and prefork MPM
2295 in the situation where MaxClients is very high but
2296 much fewer servers are actually started at the time of the
2297 restart. [Jeff Trawick]
2299 *) Small performance fixes for mod_include [Brian Pane]
2301 *) Performance improvement for the error logger [Brian Pane]
2303 *) Change configure so that Solaris 8 and above have
2304 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
2305 according to sun people solaris 8+ doesn't have a thundering
2306 herd problem [Ian Holsman]
2308 *) Allow URIs specifying CGI scripts to include '/' at the end
2309 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
2310 which ignore '/' at the end of the names of non-directories).
2311 PR 10138 [Jeff Trawick]
2313 *) implement SSLSessionCache shmht and shmcb based on apr_rmm and
2314 apr_shm. [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
2316 *) Fix apxs -g handling. Move config_vars.mk from the top build
2317 directory to the build directory. PR 10163 [Jeff Trawick]
2319 *) Fix some mod_include problems which broke evaluation of some
2320 expressions. PR 10108 [Jeff Trawick]
2322 *) Fix the calculation of request time in mod_status. [Stas Bekman]
2324 *) Fix the calculation of thread_num in the worker score structure.
2327 *) Use apr_atomic operations in managing the mod_mem_cache
2328 cache_objects for SMP scalability. (see USE_ATOMICS
2329 preprocessor directive in mod_file_cache)
2332 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
2333 preprocessor directive in mod_file_cache)
2336 *) Implement prototype mod_disk_cache for use with mod_cache.
2339 *) Add a missing manualdir entry in the Debian config.layout.
2340 [Thom May <thom planetarytramp.net>]
2342 *) Stop installing libtool for APR and tell APR where it should place
2343 its copy of libtool (via our installbuildpath layout variable).
2346 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
2347 when reading from a remote HTTP server in proxy. [Graham Leggett]
2349 *) Modify receive/send loop in proxy_http and proxy_ftp so that
2350 should it be necessary, the remote server socket is closed before
2351 transmitting the last buffer (set by ProxyIOBufferSize) to the
2352 client. This prevents the backend server from being forced to hang
2353 around while the last few bytes are transmitted to a slow client.
2354 Fix the case where no error checking was performed on the final
2355 brigade in the loop. [Graham Leggett]
2357 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
2358 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
2359 hours. [Graham Leggett, Bill Stoddard]
2361 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
2362 for a undefined variable. [Ian Holsman]
2364 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
2365 when we can't get a socket in the specified address family. We may
2366 have gotten back an IPv6 address first and yet our system is not
2367 configured to allow IPv6 sockets. [Jeff Trawick]
2369 *) Be more careful about recursively removing CVS directories. Make
2370 sure that we aren't cd'ing to their home directory first. PR: 9993
2371 [Aaron Bannert, James LewisMoss <dres lewismoss.net>]

2374 [Dirk-Jan Faber <dirk-jan selwerd.nl>, Aaron Bannert,
2375 Thom May <thom planetarytramp.net>]
2377 *) Rename the filter ordering priorities. The recent filtering fixes
2378 have showcased problems with their usage. Therefore, we need to
2379 rename them to increase the clarity. (CONTENT->RESOURCE,
2380 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
2382 Changes with Apache 2.0.33
2384 *) Fix a problem in the new --enable-layout functionality where
2385 it wouldn't allow overrides from variables like --prefix,
2386 --bindir, etc. [Thom May <thom planetarytramp.net>]
2388 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
2389 no longer hangs around waiting for the socket to close before
2390 returning exhaustive data. [Aaron Bannert]
2392 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
2393 [Thom May <thom planetarytramp.net>]
2395 *) Change mod_ssl to always do a full startup/teardown on restarts.
2396 this allows mod_ssl to be added to a server that is already
2397 running and makes it possible to add/change certs/keys after the
2398 server has been started. [Doug MacEachern]
2400 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
2401 This pipe must be a bidirectional 'console' style relay, which
2402 mod_ssl prints all prompts to the pipe's stdin, and reads the
2403 passphrases from the pipe's stdout. [William Rowe]
2405 *) Fix bug where --sysconfdir and --localstatedir were being
2406 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
2409 *) Fix --enable-layout to work again. Caution: When specifying
2410 --enable-layout, common arguments like --prefix, --exec-prefix,
2411 etc. will be ignored and the settings from the layout will be
2412 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]
2415 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
2416 regex pattern matching for the determination of which requests
2417 to use the remote proxy for. [Jim Jagielski]
2419 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
2421 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
2422 cruft in piped logs and rewritemap child processes.
2425 *) All instances of apr_lock_t have been removed and converted
2426 to one of the following new lock APIs: apr_thread_mutex.h,
2427 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
2428 use the apr_lock.h API, as the old API will soon be deprecated.
2431 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
2432 [Ralf S. Engelschall, Cliff Woolley]
2434 *) mod-include: make it handle flush'es and fix the 'false-alarm'
2435 [Justin Erenkrantz, Brian Pane, Ian Holsman]
2437 *) ap_get_*_filter_handle() functions to allow 3rd party modules
2438 to lookup filter handles so they can bypass the filter name
2439 lookup when adding filters to a request (via ap_add_*_filter_handle())
2440 [Ryan Morgan <rmorgan covalent.net>]
2442 *) Fix for multiple file buckets on Win32, where the first file
2443 bucket would cause the immediate closure of the socket on any
2444 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
2446 *) Correct Win32 failure of mmap of a segment beyond start of the
2447 file; fixes large SSL and similar transfers. [William Rowe]
2450 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
2451 multi-process mode to not "daemonize" while detaching from the
2452 controlling terminal. This is necessary for Apache to work with
2453 process-management tools like AIX's "System Resource Controller"
2454 as well as Dan Bernstein's "daemontools".
2455 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
2457 *) Convert mod_auth_digest to use the new apr_global_mutex_t
2458 type. [Aaron Bannert]
2460 *) fix bug in mod-include where it wouldn't send a unmatched
2461 part if it was at the end of a bucket [Ian Holsman]
2463 *) worker MPM: Improve logging of errors with the interface between
2464 the listener thread and worker threads. [Jeff Trawick]
2466 *) Some browsers ignore cookies that have been merged into a
2467 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
2468 are now unmerged in the http proxy before being sent to the
2469 client. [Graham Leggett]
2471 *) Fix a problem with proxy where each entry of a duplicated
2472 header such as Set-Cookie would overwrite and obliterate the
2473 previous value of the header, resulting in multiple header
2474 values (like cookies) going missing.
2475 [Graham Leggett, Joshua Slive]
2477 *) Add the server-limit and thread-limit values to the scoreboard
2478 for the sake of third-party applications.
2479 [Adam Sussman <myddryn vishnu.vidya.com>]
2481 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
2483 *) OS/390: Get make install to properly copy DSO modules.
2486 *) Win32: Fix bug in mod_status with displaying "Restart Time"
2487 and "Server uptime".
2490 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
2492 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
2494 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
2495 [David MacKenzie <djm pix.net>]
2497 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
2498 [David MacKenzie <djm pix.net>]
2500 *) Fix segfault and display error when SSLMutex file can not be
2501 created. [Adam Sussman <myddryn vishnu.vidya.com>]
2503 *) Add reference counting to mod_mem_cache cache objects to
2504 better manage removing objects from the cache.
2507 *) Change the verbage on the ScoreBoardFile in our default configs.
2508 Also change the default to be commented out (unspecified) so we
2509 get anonymous shared memory by default. [Aaron Bannert]
2511 *) Implement new ScoreBoardFile directive logic. This affects how
2512 we create the scoreboard's shared memory segment. If the directive
2513 is present, a name-based segment is created. If the directive is
2514 not present, first an anonymous segment is created, and if that
2515 fails, a name-based segment is created from a file of the name
2516 DEFAULT_SCOREBOARD. This gives third-party applications the
2517 ability to access our scoreboard. [Aaron Bannert]
2519 *) Allow mod_deflate to work with non-GET requests and properly send
2520 Content-Lengths. [Sander Striker <striker apache.org>]
2522 *) Fix ap_directory_merge() to correctly merge configs when there is
2523 no <Directory /> block. [Justin Erenkrantz, William Rowe]
2525 *) Remove spurious debug messsages that are normal under HTTP
2526 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
2528 *) Fix a bug in mod_cgid that would prevent proper shutdown death
2529 of the cgid process. [Aaron Bannert]
2531 *) Add signal handling back in to the worker MPM for the one_process
2532 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
2534 *) Performance: Reuse per-connection transaction pools in the
2535 worker MPM, rather than destroying and recreating them. [Brian Pane]
2537 *) Remove all signals from the worker MPM's child process. Instead,
2538 the parent uses the Pipe of Death for all communication with the
2539 child processes. [Ryan Bloom]
2541 Changes with Apache 2.0.32
2543 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
2544 default if the directive is not specified. This mirrors older
2545 behavior without changes to the httpd.conf. [William Rowe]
2547 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
2548 the service, mpm and logging code, and bugs in apr_file_open_stderr
2549 and apr_file_dup2 functions. Win2K/XP services have no handles
2550 associated for stdin/out/err, which caused unpredictable behavior
2551 in the prior release. [William Rowe, Bill Stoddard]
2553 *) Win32: simplify the Application Event Log messages, since there isn't
2554 likely to be 'more information in the error log' before an error log
2555 has been opened. [William Rowe]
2557 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
2558 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
2560 *) Win32: apache -k shutdown now behaves like apache -k stop.
2563 *) Fix prefork to not kill the parent if a child hits a resource shortage
2564 on accept(). [Greg Ames]
2566 *) Fix seg faults that occur when what should be the httpd request line
2567 starts with \r\n followed by garbage. [Greg Ames]
2569 *) Allow statically linked support binaries with the new
2570 --enable-static-support flag, and enable this behavior in
2571 the binbuild script. Also add a new --enable-static-htdbm
2572 flag. [Aaron Bannert]
2574 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
2575 do only one stat() call when generating the directory listings.
2578 *) Fix resolve_symlink to save the original symlink name if known.
2581 *) Be a bit more sane with regard to CanonicalNames. If the user has
2582 specified they want to use the CanonicalName, but they have not
2583 configured a port with the ServerName, then use the same port that
2584 the original request used. [Ryan Bloom and Ken Coar]
2586 *) In core_input_filter, check for an empty brigade after
2587 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
2588 client says it will post some data but we get FIN before any
2589 data arrives. [Jeff Trawick]
2591 *) Not being able to bind to the socket is a fatal error. We should
2592 print an error to the console, and return a non-zero status code.
2593 With these changes, all of the Unix MPMs do that correctly.
2596 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
2597 through to CGI scripts. PR 9163
2598 [Brian Reid <breid customlogic.com>,
2599 Zvi Har'El <rl math.technion.ac.il>]
2601 *) binbuild.sh: Make sure that we use the expat from our source
2602 tree so that there aren't any surprises on the target machine.
2605 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2606 enough to keep up with new requests. Start using
2607 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2608 when we can't talk to the daemon. [Jeff Trawick]
2610 *) apxs: LTFLAGS envvar can override default libtool options. Try
2611 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2612 the covers. [Jeff Trawick]
2614 *) The Location: response header field, used for external
2615 redirect, *must* be an absoluteURI. The Redirect directive
2616 tested for that, but RedirectMatch didn't -- it would allow
2617 almost anything through. Now it will try to turn an abs_path
2618 into an absoluteURI, but it will correctly varf like Redirect
2619 if the final redirection target isn't an absoluteURI. [Ken Coar]
2621 Changes with Apache 2.0.31
2623 *) Create the scoreboard (in the parent) in a global pool context,
2624 so it survives graceful restarts. This fixes a SEGV during
2625 graceful restarts. [Aaron Bannert]
2627 *) Add a timeout option to the proxy code 'ProxyTimeout'
2630 *) FTP directory listings are now always retrieved in ASCII mode.
2631 The FTP proxy properly escapes URI's and HTML in the generated
2632 listing, and escapes the path components when talking to the FTP
2633 server. It is now possible to browse the root directory by using
2634 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2635 Also, the last path component may contain wildcard characters
2636 '*' and '?', and if they do, a directory listing is created instead
2637 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2640 *) Added single-listener unserialized accept support to the
2641 worker MPM [Brian Pane]
2643 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2644 the incoming host header through to the proxied server
2645 [Geoff <g.russell ieee.org>]
2647 *) New Directive Option for ProxyPass. It now can block a location
2648 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
2650 *) Don't let the default handler try to serve a raw directory. At
2651 best you get gibberish. Much worse things can happen depending
2652 on the OS. [Jeff Trawick]
2654 *) Change the pre_config hook to return a value. Modules can now emit
2655 an error message and then cause the server to quit gracefully during
2656 startup. This required a bump to the MMN. [Aaron Bannert]
2658 *) Fix some unix socket descriptor leaks in the handler side of
2659 mod_cgid (the part that runs in the server process). Whack a
2660 silly "close(-1)" in the handler too. [Jeff Trawick]
2662 *) Change the pre_mpm hook to return a value, so that scoreboard
2663 init errors percolate up to code that knows how to exit
2664 cleanly. This required a bump to the MMN. [Jeff Trawick]
2666 *) Add the socket back to the conn_rec and remove the create_connection
2667 hook. The create_connection hook had a design flaw that did not
2668 allow creating connections based on vhost info. [Bill Stoddard]
2670 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2671 Resolves the common case of using negotation to resolve the request
2672 /script/foo for /script.cgi/foo. [William Rowe]
2674 *) Added new functions ap_add_(input|output)_filter_handle to
2675 allow modules to bypass the usual filter name lookup when
2676 adding hard-coded filters to a request [Brian Pane]
2678 *) caching should now work on subrequests (still very experimental)
2681 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2683 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2686 *) Refactor ap_rgetline so that it does not use an internal brigade.
2687 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2689 *) Remove mod_auth_db. [Justin Erenkrantz]
2691 *) Do not install unnecessary pcre headers like config.h and internal.h.
2692 [Joe Orton <joe manyfish.co.uk>]
2694 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
2695 (as it does for a normal request). quick_handled sub-requests now work
2696 in mod-include [Ian Holsman]
2698 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
2699 'CONTENT' one, as it needs to run AFTER all content headers
2701 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
2704 *) Split out blocking from the mode in the input filters.
2707 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
2709 *) Cause Win32 to capture all child-worker process errors in
2710 Apache to the main server error log, until the child can
2711 open its own error logs. [William Rowe]
2713 *) HPUX 11.*: Do not kill the child process when accept()
2714 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
2715 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
2717 *) Fix a problem in the parsing of the <Proxy foo> directive.
2720 *) rewrite of mod_ssl input filter for better performance and less
2721 memory usage [Doug MacEachern]
2723 *) allow quick_handler to be run on subrequests. [Ian Holsman]
2725 *) mod_dav now asks its provider to place content directly into the
2726 filter stack when handling a GET request. The mod_dav/provider
2727 API has changed, so providers need to be updated. [Greg Stein]
2729 *) Clear the output socket descriptor in unixd_accept() to make sure
2730 we don't supply a bogus socket to the caller if the accept fails.
2731 This caused problems with the worker MPM, which tried to process
2732 the returned socket if it was non-NULL. [Brian Pane]
2734 *) Move a check for an empty brigade to the start of core input filter
2735 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
2737 *) Add FileETag directive to allow configurable control of what
2738 data are used to form ETag values for file-based URIs. MMN
2739 bumped to 20020111 because of fields added to the end of
2740 the core_dir_config structure. [Ken Coar]
2742 *) Fix a segfault in mod_rewrite's logging code caused by passing the
2743 wrong config to ap_get_remote_host(). [Jeff Trawick]
2745 *) Allow mod_cgid to work from a binary distribution install by
2746 using 755 for the permissions on the log directory instead of
2749 *) Fixed a segfault that happened during graceful shutdown (or when
2750 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
2752 *) Split all Win32 modules [excluding the core components mod_core,
2753 mod_so, mod_win32 and the winnt mpm] into individual loadable
2754 modules, so the administrator may individually disable the former
2755 compiled-in modules by simply commenting out their LoadModule
2756 directives. [William Rowe]
2758 *) Saved Win32 module authors and porters many future headaches, by
2759 duplicating the appropriate .h files such as os.h into the include
2760 directory, including in the build tree. [William Rowe]
2762 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
2763 Use SSL functions/macros instead of directly dereferencing SSL
2764 structures wherever possible.
2765 Add type-casts for the cases where functions return a generic pointer.
2766 Add $SSL/include to configure search path.
2767 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
2769 *) Moved several pointers out of the shared Scoreboard so it is
2770 more portable, and will present the vhost name across server
2771 generation restarts. [William Rowe]
2773 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
2776 Changes with Apache 2.0.30
2778 *) Fix the main bug for FreeBSD and threaded MPM's. There are
2779 still issues (see STATUS) but at least the server will now
2780 run without crashing the machine.
2781 [David Reid, Aaron Bannert, Justin Erenkrantz]
2783 *) Fix a typo in mod_deflate's m4 config section.
2784 [albert chin <china thewrittenword.com>]
2786 *) Fix a couple of mod_proxy problems forwarding HTTP connections
2787 and handling CONNECT:
2788 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
2789 (2) Proxy failed to connect when the first IP address returned by
2790 the resolver was unreachable but a secondary IP address was.
2793 *) Fix the module identifer as shown in the docs for various core
2794 modules (e.g., the identifer for mod_log_config was previously
2795 listed as config_log_module). PR #9338
2796 [James Watson <ap2bug sowega.org>]
2798 *) Fix LimitRequestBody directive by placing it in the HTTP
2799 filter. [Justin Erenkrantz]
2801 *) Fix mod_proxy seg fault when the proxied server returns
2802 an HTTP/0.9 response or a bogus status line.
2805 *) Prevent mod_proxy from truncating one character off the
2806 end of the status line returned from the proxied server.
2807 [Adam Sussman, Bill Stoddard]
2809 *) Eliminate loop in ap_proxy_string_read().
2810 [Adam Sussman, Bill Stoddard]
2812 *) Provide $0..$9 results from mod_include regex parsing.
2815 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
2817 *) Introduced the ForceLanguagePriority directive, to prevent
2818 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
2819 when using Multiviews. [William Rowe]
2821 *) Fix a problem which prevented mod_cgid and suexec from working
2822 together reliably [Greg Ames]
2824 *) Remove the call to exit() from within mod_auth_digest's post_config
2825 phase. [Aaron Bannert]
2827 *) Fix a problem in mod_auth_digest that could potentially cause
2828 problems with initialized static data on a system that uses DSOs.
2831 *) Fix a segfault in the worker MPM that could happen during
2832 child process exits. [Brian Pane, Aaron Bannert]
2834 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
2836 *) Fix matching of vhosts by ip address so we find IPv4
2837 vhost address when target address is v4-mapped form of
2838 that address. [Jeff Trawick]
2840 *) More performance tweaks to the BNDM string-search algorithm
2841 used to find "<!--#" tokens in mod_include [Brian Pane]
2843 *) Miscellaneous small performance fixes: optimized away various
2844 string copy operations and removed large temp buffers from
2845 the stack [Brian Pane]
2847 *) Fixed startup segfault that occurred when a VirtualHost
2848 directive had a port but no address [Brian Pane]
2850 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
2852 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
2853 if oslevel < WINNT. This should fix several problems reported
2854 Against 2.0.28 on Windows 98 [Bill Stoddard]
2856 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
2857 to fail. [Bill Stoddard]
2859 *) Change core code to allow an MPM to set hard thread/server
2860 limits at startup. prefork, worker, and perchild MPMs now have
2861 directives to set these limits. [Jeff Trawick]
2863 *) Win32: The async AcceptEx() event should be autoreset upon
2864 successful completion of a wait (WaitForSingleObject). This
2865 eliminates a number of spurious
2866 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
2869 *) Move any load library path environment variables out of
2870 apachectl and into a separate environment variable file which
2871 can be more easily tailored by the admin. The environment
2872 variable file as built by Apache may have additional system-
2873 specific settings. For example, on OS/390 we tailor the heap
2874 settings to allow lots of threads. [Jeff Trawick]
2876 *) Use the new APR pool code to reduce pool-related lock
2877 contention in the worker MPM. [Sander Striker]
2879 *) The POD no longer assumes the child is listening on 127.0.0.1
2880 and now pulls the first hostname in the list of listeners to
2881 perform the dummy connect on. This fixes a bug when the user
2882 had configured the Listen directive for an IP other than
2883 127.0.0.1. This would result in undead children and error
2884 messages such as "Connection refused: connect to listener".
2887 *) The worker MPM now respects the LockFile setting, needed to
2888 avoid locking problems with NFS. [Jeff Trawick]
2890 *) Fix segfault when worker MPM receives SIGHUP.
2891 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
2893 *) Fix bug that could potentially prevent the perchild MPM from
2894 working with more than one vhost/uid. [Aaron Bannert]
2896 *) Change make install and apxs -i processing of DSO modules to
2897 perform special handling on platforms where libtool doesn't install
2898 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
2899 which prevented standard LoadModule statements from working.
2902 *) Whenever mod_so is enabled (not just when there are DSOs for
2903 our modules), do whatever special magic is required for compiling/
2904 loading third-party modules. This allows third-party DSOs to
2905 be used on an AIX build when there were no built-in modules
2906 built as DSOs. (This should help on OS/390 and BeOS as well.)
2909 *) Allow apxs to be used to build DSOs on AIX without requiring the
2910 user to hard-code the list of import files. (This should help
2911 on OS/390 and BeOS as well.) [Jeff Trawick]
2913 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
2914 PR 8563, 8919 [William Rowe]
2916 *) Get binary builds working when libapr and libaprutil are built
2919 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
2920 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
2921 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
2923 *) Fix the handling of SSI directives in which the ">" of the
2924 terminating "-->" is the last byte in a file [Brian Pane]
2926 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
2927 message that we had back in apache-1.3 and still have scattered
2928 throughout our docs. [Aaron Bannert]
2930 *) Prevent the Win32 port from continuing after encountering an
2931 error in the command line args to apache. [William Rowe]
2933 *) On a error in the proxy, make it write a line to the error log
2936 *) Various mod_ssl performance improvements [Doug MacEachern]
2938 Changes with Apache 2.0.29
2940 *) Add buffering in core_output_filter to ensure that long
2941 lists of small buckets don't cause small packet writes.
2942 [Brian Pane, Ryan Bloom]
2944 *) Fix the installation target to make sure that the manual is
2945 installed in the correct location.
2946 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
2947 Gomez Henri <hgomez slib.fr>]
2949 *) Fix the cmd command for mod_include. When we are processing
2950 a cmd command, we do not want to use the r->filename to set
2951 the command name. The command comes from the SSI tag. To do this,
2952 I added a variable to the function that builds the command line
2953 in mod_cgi. This allows the include_cmd function to specify
2954 the command line itself. [Ryan Bloom]
2956 *) Change open_logs hook to return a value, allowing you
2957 to flag a error while opening logs
2958 [Ian Holsman, Doug MacEachern]
2960 *) Change post_config hook to return a value, allowing you
2961 to flag a error post config
2962 [Ian Holsman, Jeff Trawick]
2964 *) Allow SUEXEC_BIN (the path to the suexec binary that is
2965 hard-coded into the server) to be specified to the configure
2966 script by the --with-suexec-bin parameter. [Aaron Bannert]
2968 *) Fix segv in worker MPM following accept on pipe-of-death
2971 *) Add mod_deflate to experimental.
2972 [Ian Holsman, Justin Erenkrantz]
2974 *) Bail out at configure time if an invalid MPM was specified.
2975 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
2977 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
2978 configured [John Sterling <sterling covalent.net>]
2980 *) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>]
2982 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
2984 *) Optimization for the BNDM string-search function in
2985 mod_include. [Brian Pane]
2987 *) Fixed the behavior of the XBitHack directive.
2988 [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
2990 *) The threaded MPM for Unix has been removed. Use the worker
2991 MPM instead. [various]
2993 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
2994 in logging the error from a failed DNS lookup. [Jeff Trawick]
2996 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
2999 *) Get mod_cgid killed when a MPM exits due to a fatal error.
3002 *) Fix a file descriptor leak in mod_include. When we include a
3003 file, we use a sub-request, but we didn't destroy the sub-request
3004 immediately, instead we waited until the original request was
3005 done. This patch closes the sub-request as soon as the data is
3006 done being generated. [Brian Pane <bpane pacbell.net>]
3008 *) Allow modules that add sockets to the ap_listeners list to
3009 define the function that should be used to accept on that
3010 socket. Each MPM can define their own function to use for
3011 the accept function with the MPM_ACCEPT_FUNC macro. This
3012 also abstracts out all of the Unix accept error handling
3013 logic, which has become out of synch across Unix MPMs.
3016 *) Fix a bug which would cause the response headers to be omitted
3017 when sending a negotiated ErrorDocument because the required
3018 filters were attached to the wrong request_rec.
3019 [John Sterling <sterling covalent.net>]
3021 *) Remove commas from the end of the macros that define
3022 directives that are used by MPMs. Prior to this patch,
3023 you would use these macros without commas, which was unlike
3024 the macros for any other directives. Now, the caller provides
3025 the comma rather than the macro providing it. This makes
3026 the macros look more like the rest of the directives.
3027 [Ryan Bloom and Cliff Woolley]
3029 *) Add 'redirect-carefully' environment option to disable sending
3030 redirects under special circumstances. This is helpful for
3031 Microsoft's WebFolders when accessing a directory resource via
3032 DAV methods. [Justin Erenkrantz]
3034 *) Begin to abstract out the underlying transport layer.
3035 The first step is to remove the socket from the conn_rec,
3036 the server now lives in a context that is passed to the
3037 core's input and output filters. This forces us to be very
3038 careful when adding calls that use the socket directly,
3039 because the socket isn't available in most locations.
3042 *) Really reset the MaxClients value in worker and threaded
3043 when the configured value is not a multiple of the number
3044 of threads per child. We said we did previously but we
3045 forgot to. [Jeff Trawick]
3047 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
3049 *) If shared modules are requested and mod_so is not available,
3050 produce a fatal config-time error. [Justin Erenkrantz]
3052 *) Improve http2env's performance by cutting the work it has to
3053 do. [Brian Pane <bpane pacbell.net>]
3055 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
3056 [Brian Pane <bpane pacbell.net>]
3058 Changes with Apache 2.0.28
3060 *) Fix infinite loop in mod_cgid.c.
3061 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
3063 *) When no port is given in a "ServerName host" directive, the
3064 server_rec->port is now set to zero, not 80. That allows for
3065 run-time deduction of the correct server port (depending on
3066 SSL/plain, and depending also on the current setting of
3067 UseCanonicalName). This change makes redirections
3068 work, even with https:// connections. As in Apache-1.3, the
3069 connection's actual port number is never used, only the ServerName
3070 setting or the client's Host: setting. Documentation updated
3071 to reflect the change. [Martin Kraemer]
3073 *) Add a '%{note-name}e' argument to mod-headers, which works in
3074 the same way as mod_log_confg. [Ian Holsman]
3076 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
3077 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
3078 MPMs. [Cliff Woolley]
3080 *) Introduce htdbm, a user management utility for db/dbm authorization
3081 databases. [Mladen Turk <mturk mappingsoft.com>]
3083 *) Optimize usage of strlen and strcat in ap_directory_walk.
3084 [Brian Pane <bpane pacbell.net>]
3086 Changes with Apache 2.0.27
3088 *) Introduce an Apache mod_ssl initial configuration template
3089 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
3091 *) Fixed a memory leak in the getline parsing code that could
3092 be triggered by arbitrarily large header lines. Requests
3093 from the core input filter for single lines are now limited
3094 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
3096 *) Fix a truncation bug in how we print the port on the Via: header.
3097 The routine that prints the Via: header now takes a length for
3098 the port string. [Zvi Har'El <rl math.technion.ac.il>]
3100 *) Some syntax errors in mod_mime_magic's magic file can result
3101 in a 500 error, which previously was unlogged. Now we log the
3102 error. [Jeff Trawick]
3104 *) Add the support/checkgid helper app, which checks the run-time
3105 validity of group identifiers usable in the Group directive.
3108 *) Various --enable-so options have been fixed: --enable-so is
3109 treated as "static"; explicit --enable-so=shared issues an error;
3110 and explicit --enable-so fails with error on systems without
3111 APR_HAS_DSO. [Aaron Bannert]
3113 *) Fix a segfault in the core input filter when the client socket
3114 gets disconnected unexpectedly. [Cliff Woolley]
3116 *) Fix the reporting for child processes that die. This removes
3117 all of the non-portable W* macros from Apache.
3118 [Jeff Trawick and Ryan Bloom]
3120 *) Win32: Track and display "Parent Server Generation:" in
3121 mod_status output. The generation will be bumped at
3122 server graceful restart, when the child process exits
3123 by hitting MaxRequestsPerChild or if the child
3124 process exits abnormally. [Bill Stoddard]
3126 *) Win32: Fix problem where MaxRequestsPerChild directive was
3127 not being picked up in favor of the default. Enable
3128 the parent to start up a new child process immediately upon
3129 the old child starting shutdown.
3132 *) Fix some bungling of the remote port in rfc1413.c so that
3133 IdentityCheck retrieves the proper user id instead of failing
3134 and thus always returning "nobody."
3135 [Dick Streefland <Dick.Streefland xs4all.nl>]
3137 *) Introduced thread saftey for mod_rewrite's internal cache.
3138 [Brian Pane <bpane pacbell.net>]
3140 *) Simplified mod_env's directives to behave as most directives are
3141 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
3142 directive following that UnsetEnv within the same container.
3143 Also provides a runtime startup warning if a PassEnv configured
3144 environment value is undefined. [William Rowe]
3146 *) The worker MPM is now completely ported to APR's new lock API. It
3147 uses native APR types for thread mutexes, cross-process mutexes,
3148 and condition variables. [Aaron Bannert]
3150 *) Sync up documentation to remove all references to the now deprecated
3151 Port directive. [Justin Erenkrantz]
3153 *) Moved all ldap modules from the core to httpd-ldap sub-project
3156 *) Exit when we can't listen on any of the configured ports. This
3157 is the same behavior as 1.3, and it avoids having the MPMs to
3158 deal with bogus ap_listen_rec structures. [Jeff Trawick]
3160 *) Cleanup the proxy code that creates a request to the origin
3161 server. This change adds an optional hook, which allows modules
3162 to gain control while the request is created if the proxy module
3163 is loaded. The purpose of this hook is to allow modules to add
3164 input and/or output filters to the request to the origin. While
3165 I was at it, I made the core use this hook, so that proxy request
3166 creation uses some of the code from the core. This can still be
3167 greatly improved, but this is a good start. [Ryan Bloom]
3169 Changes with Apache 2.0.26
3171 *) Port the MaxClients changes from the worker MPM to the threaded
3174 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
3175 with the new input filtering system. [Justin Erenkrantz]
3177 *) Introduce the MultiviewsMatch directive, to allow the operator
3178 to be flexible in recognizing Handlers and Filters filename
3179 extensions as part of the Multiviews matching logic, strict with
3180 MultiviewsMatch NegotiatedOnly to accept only filename extentions
3181 that designate negotiated parameters, (content type, charset, etc.)
3182 or MultiviewsAll for the 1.3 behavior of matching any files, even
3183 if they have unregistered extensions. [William Rowe]
3185 *) Fixed the configure script to add a LoadModule directive to
3186 the default httpd.conf for any module that was compiled
3187 as a DSO. [Aaron Bannert <aaron clove.org>]
3189 *) rewrite mod_ssl input filtering to work with the new input filtering
3190 system. [Justin Erenkrantz]
3192 *) prefork: Don't segfault when we are able to listen on some but
3193 not all of the configured ports. [Jeff Trawick]
3195 *) Build mod_so even if no core modules are built shared.
3196 [Aaron Bannert <aaron clove.org>]
3198 *) Introduce ap_directory_walk rewrite (with further optimizations
3199 required) to adapt to the ap_process_request_internal() changes.
3200 Optimized so subrequests and redirects now reuse previous section
3201 merges, until we mismatch with the original directory_walk, and
3202 precomputed r->finfo results will cause directory_walk to skip
3203 the most expensive phases of the function. [William Rowe]
3205 *) Allow ApacheMonitor to connect to and control Apache on other
3206 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
3208 *) Remove the Port directive. In it's place, the Listen directive
3209 is now a required directive, which tells Apache what port to
3210 listen on. The ServerName directive has also been extended
3211 to accept an optional port. If the port is specified to the
3212 ServerName, the server will report that port whenever it
3213 reports the port that it is listening on. This change was
3214 made to ease configuration errors that stem from having a Port
3215 directive, and a Listen directive. In that situation, the server
3216 would only listen to the port specified by the Listen command,
3217 which caused a lot of confusion to users. [Ryan Bloom]
3219 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
3220 build, as loadable modules. [William Rowe]
3222 *) Fix --enable-mods-shared processing. If most is specified,
3223 then all modules that can be compiled as shared modules are.
3224 [Aaron Bannert <aaron clove.org>]
3226 *) Update the mime.types file to map video/vnd.mpegurl to mxu
3227 and add commonly used audio/x-mpegurl for m3u extensions.
3228 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
3230 *) Eliminate the depreciated r->content_language, in favor of the array
3231 r->content_languages introduced many years ago. Module authors must
3232 substantially overhaul their modules, so this needs to be upgraded
3233 if the module still relied on backwards-brokeness. [William Rowe]
3235 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
3238 *) Rewrite the input filtering mechanisms to consolidate and reorganize
3239 code. In short, core_input_filter does something now and
3240 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
3242 *) Update the Win32 build to re-absorb mod_proxy and family.
3245 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
3246 current SDK.) [William Rowe]
3248 *) Some style changes to the code that does ProxyErrorOverride. Fixed
3249 config merge behaviour. [Graham Leggett]
3251 *) Allow support programs to be compiled against a static version
3252 of libapr. This allows the smaller support programs to be
3253 relocated. [Aaron Bannert <aaron clove.org>]
3255 *) Update the mime.types file to the registered media types as
3256 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
3258 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
3259 number of clients that can connect at the same time, instead of
3260 specifying the maximum number of child processes.
3261 [Aaron Bannert <aaron clove.org>]
3263 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
3264 be consistent with 1.3. [Justin Erenkrantz]
3266 *) Cache apr_explode_localtime() value for 15 seconds.
3267 [Brian Pane <bpane pacbell.net>]
3269 *) Fix mod_include to not return ETag or Last-Modified headers.
3270 [Ian Holsman <ianh cnet.com>]
3272 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
3274 *) Eliminate the wasteful run-time conversion of method names from strings
3275 to numbers in places where the methods are known at compile time.
3276 [Brian Pane <bpane pacbell.net>]
3278 *) Turn the worker MPM's queue into a LIFO. This may
3279 improve cache-hit performance under some conditions.
3280 [Aaron Bannert <aaron clove.org>]
3282 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
3283 support it. [Justin Erenkrantz]
3285 *) Cleanup the worker MPM. We no longer re-use transaction
3286 pools. This incurs less overhead than shuffling the pools
3287 around so that they can be re-used. Remove one of the
3288 queue's condition variables. We just redefined the API to
3289 state that you can't try to add more stuff than you allocated
3290 segments for. [Aaron Bannert <aaron clove.org>]
3292 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
3294 *) Fixed persistent connections when a request contains a body.
3297 *) mod_dav uses a new API to speak to the backend provider for dead
3298 property management. [Greg Stein]
3300 *) Remove the Win32 script-processing exception from mod_cgi, and
3301 roll build_command_line/build_argv_list into a unified, overrideable
3302 ap_cgi_build_command optional function. [William Rowe]
3304 *) Rewrite find_start_sequence to use a better search algorithm
3305 to find the start tag. [Justin Erenkrantz]
3307 *) Fix a seg fault in mod_include. When we are generating an
3308 internal redirect, we must set r->uri to "", not a bogus
3309 string, and not NULL. [Ryan Bloom]
3311 *) Optimized location_walk, so subrequests, redirects and second passes
3312 now reuse previous section merges on a <Location > by <Location >
3313 basis, until we mismatch with the original location_walk.
3316 *) Back out the 1.45 change to util_script.c. This change made
3317 us set the environment variable REQUEST_URI to the redirected
3318 URI, instead of the originally requested URI.
3319 [Taketo Kabe <kabe sra-tohoku.co.jp>]
3321 *) Make mod_include do lazy evaluation of potentially expensive to
3322 compute variables. [Brian Pane <bpane pacbell.net>]
3324 *) Fix logging of bytes sent for HEAD requests. %b and %B should
3325 log either - or 0, before this patch, they were both logging
3326 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
3328 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
3329 than per character. [Brian Pane <bpane pacbell.net>]
3331 *) Normalize the primary request, redirects and sub-requests to
3332 run the same ap_process_request_internal for consistency in
3333 robustness, behavior and security. [William Rowe]
3335 *) Fix a segfault with mod_include when r->path_info is not set
3336 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
3338 *) Add -X functionality back. This indicates to all MPMs and any other
3339 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
3341 *) Some initial support for the cygwin platform [prefork only].
3342 This is not to be confused with support for the WinNT/Win32
3343 platform, which is the recommended configuration for native
3344 Win32 users. The cygwin platform support is recommended for
3345 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
3347 *) Changed syntax of Set{Input|Output}Filter. The list of filters
3348 must be semicolon delimited (if more than one filter is given.)
3349 The Set{Input|Output}Filter directive now overrides a parent
3350 container's directive (e.g. SetInputFilter in <Directory /web/foo>
3351 will override any SetInputFilter directive in <Directory /web>.)
3352 This new syntax is more consistent with Add{Input|Output}Filter
3353 directives defined in mod_mime. Also cures a bug in prior releases
3354 where the Set{Input|Output}Filter directive would corrupt the
3355 global configuration if the multiple directives were nested.
3358 *) Cured what's ailed mime for quite some time. If an AddSomething
3359 was given in the configuration (Language, Charset, Handler or
3360 Encoding) Apache would set the content type as given by AddType,
3361 but refused to check the mime.types file if AddType wasn't given
3362 for that specific extension. Setting the AddHandler for .html
3363 without setting the AddType text/html html would cause Apache to
3364 use the default content type. [William Rowe]
3366 *) Added some bulletproofing to memory allocation in the LDAP cache
3367 code. [Graham Leggett]
3369 Changes with Apache 2.0.25
3371 *) Move the installed /manual directory out of the /htdocs/ tree, so
3372 that it can be kept more independently from the remaining document
3373 root. The "Alias /manual ..." already allowed for easy projection
3374 into existing private document trees. [Martin Kraemer]
3376 *) Add specified user attributes to the environment when using
3377 mod_auth_ldap. This allows you to use mod_include to embed specified
3378 user attributes in a page like so:
3379 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
3382 *) Fix a performance problem with the worker MPM. We now create
3383 transaction pools once, and re-use them for each connection.
3384 [Aaron Bannert <aaron clove.org>]
3386 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
3387 of a 'handler' or 'filter', so that any filename extension that does
3388 not contribute to the negotiated metadata can't be served without
3389 an explicit request. E.g., if the .Z extension is associated with
3390 an unzip filter, the user request somefile.Z.html, mod_negotiation
3391 won't serve it. It can serve somefile.Z.html when somefile.Z is
3392 requested, since the .Z extension is explictly requested, if the
3393 .html extension is associated with ContentType text/html.
3396 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
3397 and corresponding AddOutputFilter syntax, to insert one or more
3398 filters by mod_mime filename extension processing.
3401 *) Fix a growing connection pool in core_output_filter() for
3402 keepalive requests. [Jeff Trawick]
3404 *) Moved split_and_pass_pretag_buckets back to being a
3405 macro at Ryans's request. Removed the return from it
3406 by setting and returning a return code instead. Updated
3407 the code to check the return code from the macro and
3408 do the right thing. [Paul J. Reder]
3410 *) Fix a segfault when a numeric value was received for Host:.
3413 *) Add a function ap_remove_input_filter. This is to match
3414 up with ap_remove_output_filter. [Ryan Bloom]
3416 *) Clean up location_walk, so that this step performs a minimum
3417 amount of redundant effort (it must be run twice, but it will no
3418 longer reparse all <Location > blocks when the request uri
3419 hadn't changed.) [William Rowe]
3421 *) Eliminate proxy: (and all other 'special') processing from the
3422 ap_directory_walk() phase. Modules that want to use special
3423 walk logic should refer to the mod_proxy map_to_location example,
3424 with it's proxy_walk and proxysection implementation. This makes
3425 either directory_walk flavor much more legible, since that phase
3426 only runs against real <Directory > blocks.
3429 *) SECURITY: Fix a security problem in mod_include which would allow
3430 an SSI document to be passed to the client unparsed.
3431 [Cliff Woolley, Brian Pane]
3433 *) Introduce the map_to_storage hook, which allows modules to bypass
3434 the directory_walk and file_walk for non-file requests. TRACE
3435 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
3436 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
3439 *) Add the ability for mod_include to add the INCLUDES filter
3440 if the file is configured for the server-parsed handler.
3441 This makes the configuration for .shtml files much easier
3442 to understand, and allows mod_include to honor Apache 1.3
3443 config files. Based on Doug MacEachern's patch to PHP
3444 to do the same thing. [Ryan Bloom]
3446 *) force OpenSSL to ignore process local-caching and to always
3447 get/set/delete sessions using mod_ssl's callbacks
3448 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3449 Geoff Thorpe <geoff geoffthorpe.net>]
3451 *) Make the worker MPM shutdown and restart cleanly. This also
3452 cleans up some race conditions, and gets the worker using
3453 pools more cleanly. [Aaron Bannert <aaron clove.org>]
3455 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
3457 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3459 *) Fix for mod_include. Ryan's patch to check error
3460 codes put a return in the wrong place. Also, the
3461 include handler return code wasn't being checked.
3462 I don't like macros with returns, so I converted
3463 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
3464 [Paul J. Reder <rederpj raleigh.ibm.com>]
3466 *) fix segv in mod_mime if no AddTypes are configured
3467 [John Sterling <sterling covalent.net>]
3469 *) Enable ssl client authentication at SSL_accept time
3470 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3472 *) Fix a segfault in mod_include when the original request has no
3473 associated filename (e.g., we're filtering the error document for
3474 a bad URI). [Jeff Trawick]
3476 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
3478 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
3479 of httpd is started and shuts down due to socket conflict. Moving the
3480 call to ap_log_pid solves the problem.
3482 *) Changed the late-1.3 log_config substitution %c to %X, to log the
3483 status of the closed connection, as it conflicts with the far more
3484 common, historical ssl logging directive %...{var}c. [William Rowe]
3486 *) Added the common error/ tree to the build/install targets
3487 (similar to the common icons/ tree) for the multi-language error
3488 messages that Lars committed earlier. [William Rowe]
3490 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
3492 *) Added a default commented-out mod_ldap and mod_auth_ldap
3493 configuration to httpd-std.conf and httpd-win.conf
3496 *) Added documentation for mod_ldap and mod_auth_ldap.
3499 *) Enabled negative caching on attribute comparisons in the LDAP cache.
3500 Fixed a problem where the default cache TTL was set in milliseconds
3501 not microseconds causing the cache to time out almost immediately.
3504 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
3505 module code to follow APR. [Graham Leggett]
3507 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
3508 cleaned up when the connection pool pool is cleaned up.
3511 *) Fix a minor issue with Jeff Trawick's mod_include
3512 patch. Without this patch, the code will just allocate
3513 more bytes in get_combined_directive than are needed.
3516 *) Added the LDAP authentication module mod_auth_ldap.
3517 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3519 *) Added the LDAP cache and connection pooling module mod_ldap.
3520 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3522 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
3523 by allowing a module to disable itself if its prerequisites are not
3524 met. [Justin Erenkrantz]
3526 Changes with Apache 2.0.24
3528 *) Fix a couple of issues in mod_include when the tag appeared at
3529 offsets near 8192 in the file being parsed. [Jeff Trawick]
3531 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
3532 reached. [Jeff Trawick]
3534 *) Numerous improvements to the Win32 build system. Introduced command line
3535 builds without requiring .mak files for MSVC 6.0 and later versions.
3536 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
3539 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
3540 reporting of uninstalled services and other error conditions, and changed the
3541 default service name to Apache2. [William Rowe]
3543 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
3544 compatibility with existing Apache 1.3 Win32 Apache management utilites.
3545 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
3547 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
3548 [William Rowe, Greg Ames]
3550 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
3551 and RemoveCharset directives. [William Rowe]
3553 *) The Unix MPMs other than perchild now allow child server
3554 processes to use the accept mutex when starting as root and
3555 using SysV sems for the accept mutex. Previously, this
3556 combination would lead to fatal errors in the child server
3557 processes. perchild can't use SysV sems because of security
3558 issues. [Jeff Trawick, Greg Ames]
3560 *) Added Win32 revision stamp resources to all http binaries
3561 (including modules/ and support/ tools.) PR7322 [William Rowe]
3563 *) Fix ap_rvprintf to support more than 4K of data at one time.
3564 [Cody Sherr <csherr covalent.net>]
3566 *) We have always used the obsolete/deprecated Netscape syntax
3567 for our tracking cookies; now the CookieStyle directive
3568 allows the Webmaster to choose the Netscape, RFC2109, or
3569 RFC2965 format. The new CookieDomain directive allows the
3570 setting of the cookie's Domain= attribute, too. PR #s 5006,
3571 5023, 5920, 6140 [Ken Coar]
3573 *) Tweak server/Makefile so that the rules for generating exports.c
3574 are compatible with make utilities which don't expand wildcards
3575 in a dependency list (e.g., OS/390 make, certain levels of GNU
3576 make). [Jeff Trawick]
3578 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
3580 *) Begin to sanitize the MPM configuration directives. Now, all
3581 MPMs use the same functions for all common MPM directives. This
3582 should make it easier to catch all bugs in these directives once.
3583 [Cody Sherr <csherr covalent.net>]
3585 *) Close a major resource leak. Every time we had issued a
3586 graceful restart, we leaked a socket descriptor.
3589 *) Fix a problem with the new method code. We need to cast
3590 the 1 to an apr_int64_t or it will be treated as a 32-bit
3591 integer, and it will wrap after being shifted 32 times.
3592 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
3594 *) Fix a bug in mod_expires. Previous to this patch, if you
3595 told mod_expires to add 604800 seconds to the last-modified
3596 time, it actually added 604800 usec's to the last-modified time,
3597 so that when looking at the response it looked like nothing
3598 had been done. The root of the problem was that we always compute
3599 time in usec's, but we ask users to input sec's. This means we
3600 need to convert to usec's before using those values.
3603 *) The worker MPM now handles shutdown and restart requests. It
3604 definitely isn't perfect, but we do stop the servers correctly.
3605 The biggest problem right now is that SIGHUP causes the server to
3606 just die. [Ryan Bloom]
3608 Changes with Apache 2.0.23
3610 *) Use the prefork MPM by default on Unix. [various]
3612 *) Added a systray icon monitor application for Win32.
3613 [Mladen Turk <mturk mappingsoft.com>]
3615 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3616 messages written to the rewrite log.
3617 [Richard Labennett <rlabenn us.ibm.com>]
3619 *) All mod_autoindex query parsing is now quietly quashed with the
3620 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3621 still drops the column sort <a href>'s for the column headers, but
3622 IgnoreClient is required to ignore these Query options entirely.
3625 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3626 to allow the client to select plain, FancyIndexing or HTMLTable
3627 formatting, V=[0|1] to inhibit or enable version sorting, and
3628 P=pattern to return only specific files. The old Query Arguments
3629 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3630 as before), and O=A|D for ordering ascending or descending.
3633 *) Fixed an error in mod_include's directive parsing routines which
3634 caused #if, #elif, and #else expressions containing backslashes
3635 to be improperly evaluated. [Cliff Woolley]
3637 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3638 drop the icon column, SuppressRules to drop the <hr> elements,
3639 and HTMLTable to create rudimentary HTML table listings (implies
3640 FancyIndexing). [William Rowe]
3642 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3643 from Apache 1.3.15. This is needed for two reasons, first, given
3644 multiple machines within a server farm, ETags and Last-Modified
3645 stamps won't correspond from machine to machine, and second, many
3646 Unixes don't capture changes to the date or time stamp of existing
3647 files, since these don't modify the dirent itself. [William Rowe]
3649 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3650 and DirectoryWidth options from Apache 1.3.10.
3651 [William Rowe, Ken Coar]
3653 *) Eliminated FancyIndexing directive, deprecated early in Apache
3654 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3656 *) mod_autoindex now excludes any file names that would result in
3657 an error, other than a success or redirect. Also optimized
3658 the parent directory, always included except in the URI '/'.
3661 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3662 negotiated index pages, and prevent the server from defaulting
3663 to an autoindex of the directory. mod_negotiation will now die
3664 with a 500 Internal Error if it could match some filenames
3665 (e.g. for mod_dir) but none can be served. mod_negotation now
3666 refuses to serve any file with an extention that mod_mime doesn't
3667 recognize, and wasn't part of the request. [William Rowe]
3669 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3670 extension. This is already handled by multiviews, if the admin
3671 wishes to AddHandler .exe or define a content type handler and
3672 associate .exe files with that content type. Multiviews must be
3673 enabled to allow these to be served. [William Rowe]
3675 *) Speed up the server's response to a spike in incoming workload
3676 or restarts by assigning empty scoreboard slots to new processes
3677 when they are available. [Greg Ames]
3679 *) Add a handler to mod_includes.c. This handler is designed to
3680 implement the XbitHack directive. This can't be done with a
3681 fixup, because we need to check the content-type, which is
3682 only available in the handler phase. [Ryan Bloom]
3684 *) Make the includes filter check return codes from filters lower in
3685 the filter chain. If a lower level filter returns an error, then
3686 the request needs to stop immediately. This allows mod_include to
3687 stop parsing data once a lower filter recognizes an error.
3690 *) Add the ability to extend the methods that Apache understands
3691 and have those methods <limit>able in the httpd.conf. It uses
3692 the same bit mask/shifted offset as the original HTTP methods
3693 such as M_GET or M_POST, but expands the total bits from an int to
3694 an ap_int64_t to handle more bits for new request methods than
3695 an int provides. [Cody Sherr <csherr covalent.net>]
3697 *) Fix broken mod_mime behavior in merging its arguments. Possible
3698 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
3700 *) Solve many mod_ssl porting issues (too many to detail) with
3701 help from the whole team, but most notably [Ralf S. Engelschall,
3702 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3703 Doug MacEachern, William Rowe, Cliff Woolley]
3705 *) More stall fixes for the threaded & worker mpm's.
3706 Make mod_status output more accurate. Don't
3707 count workers in processes which aren't actively
3708 serving requests. [Greg Ames]
3710 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
3712 *) Add a single listener/multiple worker MPM. This MPM is
3713 definately not fully correct, but it allows us to solve many
3714 of the problems that exist in the threaded MPM. This is a
3715 modified version of the threaded MPM. [Ryan Bloom]
3717 *) Improve content generation throughout Apache, providing closer
3718 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
3719 Transitional specifications. [William Rowe]
3721 Changes with Apache 2.0.22
3723 *) Fix a problem where the threaded MPM stalls after restarts or
3724 segfaults. Also prevent multiple active processes from using
3725 the same scoreboard slot. [Greg Ames]
3727 *) Apache/Win32 now fills in the service description with Apache's
3728 server version string, including loaded and advertised modules.
3731 *) Improved support for the Win32 build, to recover gracefully from
3732 missing apr or apr-util directories or the awk interpreter,
3733 create the proper cgi-bin examples, including a test-cgi.bat, and
3734 fix the perl shebang line for printenv.pl, when installing from
3735 the build environment. [William Rowe]
3737 *) Fix a segfault in threaded.c caused by passing uninitialized
3738 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
3740 *) Use new APR number conversion functions to reduce CPU consumption
3741 when setting the content length, and in mod_log_config.
3744 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
3745 where HEAD response headers were being repeated twice for
3746 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
3747 problem in the http_header filter was exposed by the recent rewrite
3748 of the content_length filter. [Taketo Kabe, Bill Stoddard]
3750 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
3751 restarts. A garbage pointer to a vhost's server_rec from the
3752 previous generation was being left around under certain
3753 conditions. [Greg Ames]
3755 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
3756 used to appear as '(none', without the closing paren.
3757 [Günter Knauf <eflash gmx.net>]
3759 *) Improve the exports generating awk script. In the past, we had
3760 work around problems in the awk script by avoiding some #if and
3761 #ifdefs. This has bitten us many times in generating the exports.c
3762 file. This improvement allows corrects the header file parsing.
3763 [Sander Striker <striker apache.org>]
3765 Changes with Apache 2.0.21
3767 *) Resolve the Win32 htpasswd bug, where a file that existed would be
3768 overwritten, regardless of the -c flag.
3769 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
3771 *) Introduce connection sub-pools into ab. Truncating the lifetime
3772 of these allocations means that ab no longer perpetually grows
3773 its working set, running out of memory on large request attempts.
3776 *) Make scoreboard creation a hook. This allows management
3777 modules to have access to the scoreboard at the time that it is
3778 created, and at every restart request.
3779 [Cody Sherr <csherr covalent.net>]
3781 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
3782 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
3783 daemon index actually used in the scoreboard. I also
3784 updated the pertinent calls. [Paul J. Reder]
3786 *) Win32: Prevent listening sockets from being inherited by
3787 the Apache child process, CGI scripts, rotatelog process
3788 etc. If the Apache child process segfaults, any processes
3789 that the child started are not reaped. Prior to this fix,
3790 these processes inherited the listening sockets which sometimes
3791 prevented the restarted Apache child process from accepting
3792 connections (ie, the server would hang).
3795 *) Provide vhost and request strings when ExtendedStatus is on.
3798 *) Fix some issues with the pod and prefork: check the pod *after*
3799 processing a connection so that a server processing a time-
3800 consuming request bails out as soon as practical; when the
3801 parent process wakes up a server process via connect(), use an
3802 APR timeout on the connect() so that we don't hang for a long
3803 time if there aren't server processes around to do accept().
3804 [Jeff Trawick, Greg Ames]
3806 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
3807 spends a lot of time in apr_table_get calls. Using the default
3808 httpd.conf, the tables for languages and charsets are somewhat
3809 large, so the time spent scanning them on each request is
3810 significant. Replacing the tables with hash tables provides
3811 a nice speedup. [Brian Pane <bpane pacbell.net>]
3813 *) Add two functions to allow modules to access random parts of the
3814 scoreboard. This allows modules compiled for one MPM to access the
3815 scoreboard, even if it the server was compiled for another MPM.
3816 [Harrie Hazewinkel <harrie covalent.net>]
3818 Changes with Apache 2.0.20
3820 *) Fix problem in content-length filter where the filter would
3821 buffer all the output from a CGI before sending any bytes
3822 down the filter stack to the network. This problem would cause
3823 significant memory consumption if the CGIs generated
3824 lots of bytes. [Bill Stoddard]
3826 *) Get non-blocking CGI pipe reads working with the bucket brigades.
3829 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
3832 *) Fix a bug in the threaded MPM that would cause it to kill off all
3833 workers immediately after starting if the number of workers started
3834 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
3836 Changes with Apache 2.0.19
3838 *) Fix problem with threaded MPM. The problem was that if each child
3839 process was busy serving a single long-lived request and the server
3840 was sent a graceful restart signal, the server would stop serving
3841 requests. This would happen because each child process would wait to
3842 die until the last thread was done, and the parent wouldn't spawn any
3843 new children until a process died. Now, the parent looks at the fact
3844 that the children are dying gracefully, and starts new children.
3845 Those new children only start enough threads to compliment the number
3846 of threads in the other child process that shares the same spot in
3847 the scoreboard. In this way, we make sure to never go over
3848 MaxClients. [Ryan Bloom]
3850 *) modified mod_negotiation and mod_autoindex to speed up by almost a
3851 factor of two on apr_dir_read()-enhanced platforms, such as Win32
3852 and OS2, by calling ap_sub_request_lookup_dirent() with the results
3853 already provided by apr_dir_read(). [William Rowe]
3855 *) mod_file_cache is now more robust to filtering and serves requests
3856 slightly more efficiently. [Cliff Woolley]
3858 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
3859 Module was calling ap_rwrite() followed by ap_rflush() but the
3860 served content was not being displayed in the browser. Inspection
3861 of the output stream revealed that the first data chunk was
3862 missing the trailing CRLF required by the RFC. [Bill Stoddard]
3864 *) apxs no longer generates ap_send_http_header() in the example handler
3866 *) Fix an ab problem which could cause a divide-by-zero exception
3867 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
3868 [Ian Holsman <ianh cnet.com>]
3870 *) Solve case-insensitive platforms' confusion about negotiated
3871 filenames, allowing files of differnt case to match in choosing
3872 the document to serve. [William Rowe]
3874 *) Fix brokenness when ThreadsPerChild is higher than the built-in
3875 limit. We left ap_threads_per_child at the higher value which
3876 led to segfaults when doing certain scoreboard operations.
3879 *) Fix seg faults and/or missing output from mod_include. The
3880 default_handler was using the subrequest pool for files and
3881 MMAPs, even though the associated APR structures typically
3882 live longer than the subrequest. [Greg Ames]
3884 *) Extend mod_setenvif to support specifying regular expressions
3885 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
3886 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
3887 will cause HAVE_TS to be set if any of the request headers begins
3888 with "TS" and has a value that begins with any character in the
3889 set [a-z]. [Bill Stoddard]
3891 *) httpd children now re-bind themselves to a random CPU on
3892 multiprocessor systems on AIX via bindprocessor() in 2.0.
3893 [Victor J. Orlikowski]
3895 *) Fix htdigest. It would go into a loop in getline when adding
3896 a second user. [Bill Stoddard]
3898 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
3900 *) Automatically generate httpd.exp for AIX.
3901 DSOs now work again on AIX in 2.0
3902 [Victor J. Orlikowski]
3904 *) Add a new request hook, error_log. This phase allows modules
3905 to act on the error log string _after_ it has been written
3906 to the error log. The goal for this hook is to allow monitoring
3907 modules to send the error string to the monitoring agent.
3910 *) Modify mod_echo to make it use filters for input and output.
3911 [Ryan Morgan <rmorgan covalent.net>]
3913 *) Extend mod_headers to support conditional driven Header
3914 add, append and set. Use SetEnvIf to set an envar and conditionally
3915 add/append/set headers based on this envar thusly:
3917 SetEnvIf TSMyHeader value HAVE_TSMyHeader
3918 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
3920 If the request contains header "TSMyHeader: value" then header
3921 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
3924 *) Extend mod_headers to support using format specifiers on Header
3925 add, append and set header values. Two format specifiers are supported:
3927 %t - reports, in UTC microseconds since the epoch, when the
3928 request was received.
3930 %D - reports the time, in microseconds, between when the request was
3931 received and the response sent.
3934 Header add MyHeader "This request served in %D microseconds. %t"
3936 results in a header being added to the response that looks like this:
3938 MyHeader: This request served in D=5438 microseconds. t=991424704447256
3942 *) Fix reset_filter(). We need to be careful how we remove filters.
3943 If we set r->output_filters to NULL, we also have to reset the
3944 connection's filters. [John Sterling]
3946 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
3948 *) Add a check to ap_die() to make sure the filter stack is sane and
3949 contains the correct basic filters when an error occurs. This fixes
3950 a problem where headers are not being sent on error. [John Sterling]
3952 *) New Header directive 'echo' option. "Header echo regex" will
3953 cause any headers received on the request that match regex to be
3954 echoed to (included in) the response headers.
3957 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
3958 This prevented the inclusion of apr_compat.h. PR #7773
3959 [Oleg Broytmann <phd phd.pp.ru>]
3961 *) Moved util_uri to the apr-util library. This required a bunch of
3962 apr_name changes for the uri utility functions. [Justin Erenkrantz]
3964 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
3965 insert_filter phase so that other filters are not bypassed by default.
3968 *) Reimplement mod_headers as an output filter. mod_headers can now
3969 add custom headers to inbound requests using the RequestHeader directive
3970 and to responses using the same old Header directive. [Graham Leggett]
3972 Changes with Apache 2.0.18
3974 *) Fix command-line processing so that if a bad argument is specified
3975 Apache will exit. [Jeff Trawick]
3977 *) Change the make targets and rules to be consistent in all of the
3978 Apache-owned source trees. [Roy Fielding]
3980 *) Fix processing of the TRACE method. Previously we passed bogus
3981 parms to form_header_field() and it overlaid some vhost structures,
3982 resulting in a segfault in check_hostalias().
3983 [Greg Ames, Jeff Trawick]
3985 *) Win32: Add support for reliable piped logs. If the logging process
3986 goes down, Apache will automatically restart it. This function has
3987 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
3990 *) Do not start piped log processes during the config file
3991 preflight. This change also circumvents a problem on
3992 Windows where the rotatelog processes created during preflight
3993 was not getting cleaned up properly.
3996 *) add "Request Phase Participation" info to mod_info
3999 *) Make first phase changes to the scoreboard data structures in
4000 preparation for the rewriting of the scoreboard per my posted
4001 design notes. [Paul J. Reder]
4003 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
4004 and apr-util, allow it to be overridden by the configure command-line
4005 (default="--silent") and introduce LT_LDFLAGS to replace what we were
4006 formerly abusing as LTFLAGS. [Roy Fielding]
4008 *) Clean up the reporting of incorrect closing container tags.
4009 [Barrie Slaymaker <barries slaysys.com>]
4011 *) Simplify the configure process by moving all libtool stuff to APR
4012 and moving hints.m4 inline. [Roy Fielding]
4014 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
4015 of functions used by mod_proxy for export in the DLL
4016 [Ian Holsman <IanH cnet.com>]
4018 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
4019 request body from its stdin but no reqest body is being written to
4020 the cgi. [Jeff Trawick]
4022 *) mod_log_config: %c connection status incorrectly logged
4023 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
4026 *) Get mod_cern_meta working under Windows
4029 *) Create Files, and thus MMAPs, out of the request pool, not the
4030 connection pool. This solves a small resource leak that had us
4031 not closing files until a connection was closed. In order to do
4032 this, at the end of the core_output_filter, we loop through the
4033 brigade and convert any data we have into a single HEAP bucket
4034 that we know will survive clearing the request_rec.
4035 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
4038 *) Completely revamp configure so that it preserves the standard make
4039 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
4040 the configure additions to EXTRA_* variables. Also, allow the user
4041 to specify NOTEST_* values for all of the above, which eliminates the
4042 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
4043 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
4044 avoid pointless duplications. Fix the order in which flags are given
4045 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
4046 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
4047 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
4048 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
4050 *) Get mod_tls to compile/work better on Windows. PR #7612
4051 [Bernhard Schrenk <b.schrenk improx.com>]
4053 *) Fix shutdown/restart hangs in the threaded MPM.
4054 [Jeff Trawick, Greg Ames, Ryan Bloom]
4056 *) Removed the keptalive boolean from conn_rec because it is now only
4057 used by a single routine and can be replaced by a local variable.
4058 [Greg Stein, Ryan Bloom, Roy Fielding]
4060 *) Patch prefork to put enough of the signal processing back in so that
4061 signals are all handled properly now. The previous patch fixed the
4062 deadlock race condition, but broke the user directed signal handling.
4063 This fixes it to work the way it did before my previous prefork patch
4064 (primarily, SIGTERM is now working).
4066 *) Change how input filters decide how much data is returned to the
4067 higher filter. We used to use a field in the conn_rec, with this
4068 change, we use an argument to ap_get_brigade to determine how much
4069 data is retrieved. [Ryan Bloom]
4071 *) Fix seg fault at start-up introduced by Ryan's change to enable
4072 modules to specify their own logging tags. mod_log_config
4073 registers an optional function, ap_register_log_handler().
4074 ap_register_log_handler() was being called by http_core before
4075 the directive hash table was created. This patch creates the
4076 directive hash table before ap_register_log_handler() is
4077 registered as an optional function.
4078 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4080 *) Add ap_set_int_slot() function
4081 [John K. Sterling <sterling covalent.net>]
4083 *) Under certain circumstances, Apache did not supply the
4084 right response headers when requiring authentication.
4085 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
4086 (This is a port of the change that went into Apache 1.3.19.)
4088 *) Allow modules to specify their own logging tags. This basically
4089 allows a module to tell mod_log_config that when %x is encountered
4090 a specific function should be called. Currently, x can be any single
4091 character. It may be more useful to make this a string at some point.
4094 Changes with Apache 2.0.17
4096 *) If a higher-level filter handles the byterange aspects of a
4097 request, then the byterange filter should not try to redo the
4098 work. The most common case of this happening, is a byterange
4099 request going through the proxy, and the origin server handles
4100 the byterange request. The proxy should ignore it.
4101 [Graham Leggett <minfrin sharp.fm>]
4103 *) Changed the threaded mpm to have child_main join to each of the
4104 worker threads to make sure the kids are all gone before child_main
4105 exits after a signal (cleanup from perform_idle_server_maintenance).
4106 This is an extension of Ryans recent commit to make the child_main
4109 *) Add more options to the ap_mpm_query function. This also allows MPMs to
4110 report if their threads are dynamic or static. Finally, this also
4111 implements a new API, ap_show_mpm, which returns the MPM that was
4112 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
4114 *) Do not install the binaries from the support directory twice.
4115 [jun-ichiro hagino <itojun iijlab.net>]
4117 *) The ap_f* functions should flush data to the filter that is passed
4118 in, not the filter after the one passed in.
4119 [Ryan Morgan <rmorgan covalent.net>]
4121 *) Make ab work again by changing its native types to apr types and formats.
4122 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4124 *) Move the byterange filter and all of the supporting functions back
4125 to the HTTP module. The byterange filter turned out to be very
4126 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
4128 *) Make clean, distclean, and extraclean consistently according to the
4129 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4131 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
4132 This may have been causing problems stopping processes in the threaded
4135 *) Fix content-length in mod_negotiation to a long int representation.
4138 *) Remove BindAddress from the default config file.
4139 [<giles nemeton.com.au>]
4141 *) Allow module authors to add a module to their Apache build using
4142 --with-module, without re-running buildconf. The syntax is:
4143 --with-module=module_type:/path/to/module.c
4144 The configure script will copy the module.c file to
4145 modules/module_type, and it will be added to the relevant Makefiles.
4146 currently, this only works for static modules. [Ryan Bloom]
4148 *) Changes required to make prefork clean up idle children properly.
4149 There was a window during which a starting worker deadlocks when
4150 an idle cleanup arrives before it completes init. Apache then keeps
4151 trying to cleanup the same deadlocked worker forever (until higher
4152 pids come along, but it still will never reduce below the deadlocked
4153 pid). Thus the number of children would not reduce to the correct
4154 idle level. [Paul J. Reder]
4156 Changes with Apache 2.0.16
4158 *) Change the default installation directory to /usr/local/apache2,
4159 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
4161 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
4164 *) Get MaxRequestsPerChild working with the Windows MPM.
4167 *) Make generic hooks to work, with mod_generic_hook_import/export
4168 experimental modules. [Ben Laurie, Will Rowe]
4170 *) Fix segfaults for configuration file syntax errors such as
4171 "<Directory>" followed by "</Directory" and
4172 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
4174 *) Cleanup the --enable-layout option of configure. This makes
4175 us use a consistent location for the config.layout file, and it
4176 makes configure more portable.
4177 [jun-ichiro hagino <itojun iijlab.net>]
4179 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
4180 csv/gnuplot format, rudimentary ssl support and various other tweaks
4181 to make results more true to what is measured. The upshot of this it
4182 turns out that 'ab' has often underreported the true performance of
4183 apache. Often by a order of magnitude :-) See talk/paper of Sander
4184 Temme at April ApacheCon 2001 for details.
4185 [Dirk-Willem van Gulik]
4187 *) Clean up mod_cgid's temporary request pool. Besides fixing a
4188 storage leak this ensures that some unnecessary pipes are closed.
4191 *) Performance: Add quick_handler hook. This hook is called at the
4192 very beginning of the request processing before location_walk,
4193 translate_name, etc. This hook is useful for URI keyed content
4194 caches like Mike Abbott's Quick Shortcut Cache.
4197 *) top_module global variable renamed to ap_top_module [Perl]
4199 *) Move ap_set_last_modified to the core. This is a potentially
4200 controversial change, because this is kind of HTTP specific. However
4201 many protocols should be able to take advantage of this kind of
4202 information. I expect that headers will need one more layer of
4203 indirection for multi-protocol work, but this is a small step in
4204 the right direction. [Ryan Bloom]
4206 *) Enable mod_status by default. This matches what Apache 1.3 does.
4209 *) Add a ScriptSock directive to the default config file. This is
4210 only enabled when mod_cgid is used.
4211 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4213 Changes with Apache 2.0.15
4215 *) Untangled the buildconf script and eliminated the need for build's
4216 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
4217 libtool muck that is now under srclib/apr/build. [Roy Fielding]
4219 *) Win32: Don't accept more connections than we have worker threads
4223 *) Fix bug in the Unix threaded.c MPM that allowed child processes
4224 to fork() new child processes.
4227 *) SECURITY: Fix a major security problem with double-reverse lookup
4228 checking. Previously, a client connecting over IPv4 would not be
4229 matched properly when the server had an IPv6 listening socket.
4230 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
4232 *) Change the way the beos MPM handles polling to allow it to stop and
4233 restart. Problem was the sockets being polled were being reset by
4234 the select call, so once it had accepted a connection it was no
4235 longer listening on the UDP socket we use for shutdown instructions.
4236 APR needs to be altered, patch on it's way. [David Reid]
4238 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
4239 on error exit from ap_getline(). Some other code got upset because
4240 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
4242 *) Handle ap_discard_request_body() being called more than once.
4243 [Greg Ames, Jeff Trawick]
4245 *) Get rid of an inadvertent close of file descriptor 2 in
4246 mod_mime_magic. [Greg Ames, Jeff Trawick]
4248 *) Add a hook, create_request. This hook allows modules to modify
4249 a request while it is being created. This hook is called for all
4250 request_rec's, main request, sub request, and internal redirect.
4251 When this hook is called, the r->main, r->prev, r->next
4252 pointers have been set, so modules can determine what kind of
4253 request this is. [Ryan Bloom]
4255 *) Cleanup the build process a bit more. The Apache configure
4256 script no longer creates its own helper scripts, it just
4258 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4260 *) Stop the forced downgrade of the connection to HTTP/1.0 for
4261 proxy requests. [Graham Leggett]
4263 *) Avoid using sscanf to determine the HTTP protocol number in
4264 the common case because sscanf is a performance hog. From
4265 Mike Abbot's Accelerating Apache patch number 6.
4266 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
4268 *) SECURITY: Fix a security exposure in mod_access. Previously when
4269 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
4270 were not evaluated properly (PR #7407). Also, add the ability to
4271 specify IPv6 address strings with optional prefix length on Allow
4272 and Deny. [Jeff Trawick]
4274 *) Enhance rotatelogs so that a UTC offset can be specified, and
4275 the logfile name can be formatted using strftime(3). (Brought
4276 forward from 1.3.) [Ken Coar]
4278 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
4279 DuplicateHandle on an IOCompletionPort (a practice which
4280 MS "discourages"). The new model does not rely on associating
4281 the completion port with the listening sockets, thus the
4282 completion port can be completely managed within the child
4283 process. A dedicated thread accepts connections off the network,
4284 then calls PostQueuedCompletionStatus() to wake up worker
4285 threads blocked on the completion port.
4288 *) Bring forward the --suexec-umask option which allows the
4289 builder to preset the umask for suexec processes. [Ken Coar]
4291 *) Add a -V flag to suexec, which causes it to display the
4292 compile-time settings with which it was built. (Only
4293 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
4295 *) Mod_include should always unset the content-length if the file is
4296 going to be passed through send_parsed_content. There is no to
4297 determine if the content will change before actually scanning the
4298 entire content. It is far safer to just remove the C-L as long
4299 as we are scanning it. [Ryan Bloom]
4301 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
4302 request and not Proxy-Authenticate.
4303 [Graham Leggett <minfrin sharp.fm>]
4305 Changes with Apache 2.0.14
4307 *) Fix content-length computation. We ONLY compute a content-length if
4308 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
4309 or we already have all the data. [Ryan Bloom]
4311 *) Report unbounded containers in the config file. Previously, a typo
4312 in the </container> directive could result in the rest of the config
4313 file being silently ignored, with undesired defaults used.
4316 *) Make the old_write filter use the ap_f* functions for the buffering.
4319 *) Move more code from the http module into the core server. This
4320 is core code, basically the default handler, the default input
4321 and output filters, and all of the core configuration directives.
4322 All of this code is required in order for the server to work, with or
4323 without HTTP. The server is closer to working without the HTTP
4324 module, although there is still more to do. [Ryan Bloom]
4326 *) Fix a number of SGI compile warnings throughout the server. Fix some
4327 bad parameters to apr_bucket_read(). Fix a bad statement in
4328 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
4329 consistently; we were mixing apr_time_t and time_t in invalid ways
4330 before. In load_file(), call apr_dso_error() instead of
4331 apr_strerror() so that we get a more specific string on some platforms.
4332 PR #6980 [Jeff Trawick]
4334 *) Allow modules to query the MPM about it's execution profile. This
4335 query API can and should be extended in the future, but for now,
4336 max_daemons, and threading or forking is a very good start.
4337 [Jon Travis <jtravis covalent.net>]
4339 *) Modify mod_include to send blocks of data no larger than 9k.
4340 Without this, mod_include will wait until the whole file is parsed,
4341 or the first tag is found to send any data to the client.
4342 [Paul J. Reder <rederpj raleigh.ibm.com>]
4344 *) Fix mod_info, so that <Directory> and <Location> directives are
4345 not displayed twice when displaying the current configuration.
4346 [Ryan Morgan <rmorgan covalent.net>]
4348 *) Add config directives to override DEFAULT_ERROR_MSG and
4349 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
4350 [Dan Rench <drench xnet.com>]
4352 *) Get mod_info building and loading on Win32. [William Rowe]
4354 *) Begin to move protocol independant functions out of mod_http. The goal
4355 is to have only functions that are HTTP specific in the http directory.
4358 Changes with Apache 2.0.13
4360 *) Don't assume that there will always be multiple calls to the byterange
4361 filter. It is possible that we will need to do byteranges with only
4362 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
4364 *) Move the error_bucket definition from the http module to the
4365 core server. Every protocol will need this ability, not just
4368 Changes with Apache 2.0.12
4370 *) Modify mod_file_cache to save pre-formatted strings for
4371 content-length and last-modified headers for performance.
4372 [Mike Abbot <mja trudge.engr.sgi.com>]
4374 *) Namespace protect IOBUFSIZ since it is exposed in the API.
4375 [Jon Travis <jtravis covalent.net>]
4377 *) Use "Basic" authentication instead of "basic" in ab, as the spec
4378 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
4380 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
4381 without ever filling it out. This fixes PR 7271.
4382 [Taketo Kabe <kabe sra-tohoku.co.jp> and
4383 Cliff Woolley <cliffwoolley yahoo.com>]
4385 *) Add a couple of GCC attribute tags to printf style functions.
4386 [Jon Travis <jtravis covalent.net>]
4388 *) Add the correct language tag for interoperation with the Taiwanese
4389 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
4391 *) Migrate the perchild MPM to use the new apr signal child, and
4392 APR thread functions. [Ryan Bloom]
4394 *) Close one copy of the CGI's stdout before creating the new process.
4395 The CGI will still have stdout, because we have already dup'ed it.
4396 This keeps Apache from waiting forever to send the results of a CGI
4397 process that has forked a long-lived child process.
4398 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4400 *) Remove the rest of the pthreads functions from the threaded MPM.
4401 This requires the APR support for a signal thread that was just
4404 *) Make mod_dir use a fixup for sending a redirect to the browser.
4405 Before this, we were using a handler, which doesn't make much
4406 sense, because the handler wasn't generating any data, it would
4407 either return a redirect error code, or DECLINED. This fits the
4408 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
4410 *) Make the threaded MPM use APR threads instead of pthreads.
4413 *) Get mod_tls to the point where it actually appears to work in all cases.
4416 *) implement --enable-modules and --enable-mods-shared for "all" and
4417 "most". [Greg Stein]
4419 *) Move the threaded MPM to use APR locks instead of pthread locks.
4422 *) Rename mpmt_pthread to threaded. This is more in line with the
4423 fact that mpmt_pthread shouldn't be using pthreads directly, and
4424 it is a smaller name that doesn't tie into anything.
4427 *) Rename the module structures so that the exported symbol matches
4428 the file name, and it is easier to automate the installation
4429 process (generating LoadModule directives from the module filenames).
4432 *) Remove the coalesce filter. With the ap_f* functions, this filter
4433 is no longer needed. [Ryan Bloom]
4435 Changes with Apache 2.0.11
4437 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
4438 added feature of allowing a uid/gid per child process. If no
4439 uid/gid is specified, then Perchild behaves exactly like dexter.
4442 *) Get perchild building again. [Ryan Bloom]
4444 *) Don't disable threads just because we are using the prefork MPM.
4445 If somebody wants to compile without threads, they must now add
4446 --disable-threads to the configure command line. [Ryan Bloom]
4448 *) Begin to move the calls to update_child_status into common code, so
4449 that each individual MPM does not need to update the scoreboard itself.
4452 *) Allow mod_tls to compile under Unix boxes where openssl has been
4453 installed to the system include files.
4454 [Gomez Henri <new-httpd slib.fr>]
4456 *) Cleanup the mod_tls configure process. This should remove any need
4457 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
4458 configure doesn't check that yet. [Ryan Bloom]
4460 *) Add a very early prototype of SSL support (in mod_tls.c). It is
4461 vital that you read modules/tls/README before attempting to build
4464 *) Fix a potential seg fault on all platforms. David Reid fixed this
4465 on BEOS, but the problem could happen anywhere, so we don't want
4466 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
4468 *) Add new LogFormat directive, %D, to log time it takes to serve a
4469 request in microseconds. [Bill Stoddard]
4471 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
4472 SetOutputFilter. This corresponds nicely with the other Set
4473 directives, which operate on containers while the Add* directives
4474 tend to work directly on extensions. [Ryan Bloom]
4476 *) Cleanup the header handling a bit. This uses the apr_brigade_*
4477 functions for the buffering so that we don't need to compute
4478 the length of the headers before we actually create the header
4479 buffer. [Ryan Bloom]
4481 *) Allow filters to buffer data using the ap_f* functions. These have
4482 become macros that resolve directly to apr_brigade_*.
4485 *) Get the Unix MPM's to do a graceful restart again. If we are going
4486 to register a cleanup with ap_cleanup_scoreboard, then we have to
4487 kill the cleanup with the same function, and that function can't be
4488 static. [Ryan Bloom]
4490 *) Install all required header files. Without these, it was not
4491 possible to compile some modules outside of the server.
4494 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
4495 forward from 1.3 to 2.0, we missed a single line, which broke regex
4496 aliases. [Ryan Bloom]
4498 *) We have a poor abstraction in the protocol. This is a temporary
4499 hack to fix the bug, but it will need to be fixed for real. If
4500 we find an error while sending out a custom error response, we back
4501 up to the first non-OK request and send the data. Then, when we send
4502 the EOS from finalize_request_protocol, we go to the last request,
4503 to ensure that we aren't sending an EOS to a request that has already
4504 received one. Because the data is sent on a different request than
4505 the EOS, the error text never gets sent down the filter stack. This
4506 fixes the problem by finding the last request, and sending the data
4507 with that request. [Ryan Bloom]
4509 *) Make the server status page show the correct restart time, and
4510 thus the proper uptime. [Ryan Bloom]
4512 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
4513 should reduce the amount of duplicate code that is required to
4514 create CGI processes.
4515 [Paul J. Reder <rederpj raleigh.ibm.com>]
4517 *) ap_new_connection() closes the socket and returns NULL if a socket
4518 call fails. Usually this is due to a connection which has been
4519 reset. [Jeff Trawick]
4521 *) Move the Apache version information out of httpd.h and into release.h.
4522 This is in preparation for the first tag with the new tag and release
4523 system. [Ryan Bloom]
4525 *) Begin restructuring scoreboard code to enable adding back in
4526 the ability to use IPC other than shared memory.
4527 Get mod_status working on Windows again. [Bill Stoddard]
4529 *) Make mod_status work with 2.0. This will work for prefork,
4530 mpmt_pthread, and dexter. [Ryan Bloom]
4532 *) Correct a typo in httpd.conf.
4533 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
4535 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
4537 *) Get the correct IP address if ServerName isn't set and we can't
4538 find a fully-qualified domain name at startup.
4539 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
4541 *) Make mod_cgid work with SuExec. [Ryan Bloom]
4543 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
4544 'extra' stat's for user/group since they should never occur, and now
4545 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
4546 volumes. [William Rowe]
4548 *) Adopt apr features to simplify mod_includes. This changes the
4549 behavior of the USER_NAME variable, unknown uid's are now reported
4550 as USER_NAME="<unknown>" rather than the old user#000 result.
4551 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
4553 *) Adopt apr features for simplifing mod_userdir, and accept the new
4554 Win32/OS2 exceptions without hiccuping. [William Rowe]
4556 *) Replace configure --with-optim option by using and saving the
4557 environment variable OPTIM instead. This is needed because configure
4558 options do not support multiple flags separated by spaces.
4561 *) Fix some byterange handling. If we get a byte range that looks like
4562 "-999999" where that is past the end of the file, we should return
4563 a PARTIAL CONTENT status code, and return the whole file as one big
4564 byterange. This matches the 1.3 handling now. [Ryan Bloom]
4566 *) Make the error bucket a real meta-data bucket. This means that the
4567 bucket length is 0, and a read returns NULL data. If one of these
4568 buckets is passed down after the headers are sent, this data will
4569 just be ignored. [Greg Stein]
4571 *) The prefork MPM wasn't killing child processes correctly if a restart
4572 signal was received while the process was serving a request. The child
4573 process would become the equivalent of a second parent process. If
4574 we break out of the accept loop, then we need to do die after cleaning
4575 up after ourselves. [Ryan Bloom]
4577 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
4578 restarts. [Ryan Bloom]
4580 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
4581 the most optimal APR_FINFO_wanted bits. This spares Win32 from
4582 performing very expensive owner, group and permission lookups
4583 and allows the server to function until these apr_finfo_t fields
4584 are implemented under Win32. [William Rowe]
4586 *) Support for typedsafe optional functions - that is functions exported by
4587 optional modules, which, therefore, may or may not be present, depending
4588 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
4589 for sample code. [Ben Laurie]
4591 *) filters can now report an HTTP error to the server. This is done
4592 by sending a brigade where the first bucket is an error_bucket.
4593 This bucket is a simple bucket that stores an HTTP error and
4594 a string. Currently the string is not used, but it may be needed
4595 to output an error log. The http_header_filter will find this
4596 bucket, and output the error text, and then return
4597 AP_FILTER_ERROR, which informs the server that the error web page
4598 has already been sent. [Ryan Bloom]
4600 *) If we get an error, then we should remove all filters except for
4601 those critical to serving a web page. This fixes a bug, where
4602 error pages were going through the byterange filter, even though
4603 that made no sense. [Ryan Bloom]
4605 *) Relax the syntax checking of Host: headers in order to support
4606 iDNS. PR#6635 [Tony Finch]
4608 *) Cleanup the byterange filter to use the apr_brigade_partition
4609 and apr_bucket_copy functions. This removes a lot of very messy
4610 code, and hopefully makes this filter more stable.
4613 *) Remove AddModule and ClearModuleList directives. Both of these
4614 directives were used to ensure that modules could be enabled
4615 in the correct order. That requirement is now gone, because
4616 we use hooks to ensure that modules are in the correct order.
4619 *) When SuExec is specified, we need to add it to the list of
4620 targets to be built. If we don't, then any changes to the
4621 configuration won't affect SuExec, unless 'make suexec' is
4622 specifically run. [Ryan Bloom]
4624 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4625 the APR_XTHREAD argument to open a file for consumption by
4626 parallel threads on win32. [William Rowe]
4628 *) Correct a bug in determining when we follow symlinks. The code
4629 expected a stat -1 result, not an apr_status_t positive error.
4630 Also check if the APR_FINFO_USER fields are valid before we
4631 follow the link. [William Rowe]
4633 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4634 mpm_common.c. These functions are only valid on some platforms,
4635 so they should not be in the main-line code. [Ryan Bloom]
4637 *) Remove ap_chdir_file(). This function is not thread-safe,
4638 and nobody is currently using it. [Ryan Bloom]
4640 *) Do not try to run make depend if there are no .c files in the
4641 current directory, doing so makes `make depend` fail.
4644 *) Update highperformance.conf to work with either prefork or
4645 pthreads mpms. [Greg Ames]
4647 *) Stop checking to see if this is a pipelined request if we know
4648 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4649 This keeps us from making an extra read call when serving a 1.0
4650 request. [Ryan Bloom and Greg Stein]
4652 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4653 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4654 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4656 *) Fix the RFC number mentioned when complaining about a missing
4657 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
4659 *) Fix an endless loop in ab which occurred when ab was posting
4660 and the server dropped the connection unexpectedly.
4663 *) Fix a segfault while handling request bodies in ap_http_filter().
4664 This problem has been seen with mod_dav usage as well as with
4665 requests where the body was just being discarded. [Jeff Trawick]
4667 *) Some adjustment on the handling and automatic setting (via
4668 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4669 add the capability to specify flags (NOTEST_CFLAGS and
4670 NOTEST_LDFLAGS) which are used to compile Apache, but
4671 not used during the configuration process. Useful for
4672 flags like "-Werror". [Jim Jagielski]
4674 *) Stop using environment variables to force debug mode or
4675 no detach. We now use the -D command line argument to
4676 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4677 [Greg Stein, Ryan Bloom]
4679 *) Change handlers to use hooks. [Ben Laurie]
4681 *) Stop returning copies of filenames from both apr_file_t and
4682 apr_dir_t. We pstrdup the filenames that we store in the
4683 actual structures, so we don't need to pstrdup the strings again.
4686 *) mod_cgi: Fix some problems where the wrong error value was being
4687 traced. [Jeff Trawick]
4689 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
4692 *) Add generic hooks. [Ben Laurie]
4694 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
4696 *) Fix a segfault caused by mod_ext_filter when the external filter
4697 program does not exist. [Jeff Trawick]
4699 *) Fix an output truncation error when on an HTTP >= 1.0 request an
4700 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
4701 was served through mod_charset_lite (or anything else that would
4702 create a transient bucket in this size range). ap_bucket_make_heap()
4703 silently failed (fixed), transient_setaside() discovered it, but
4704 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
4706 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
4707 is that some browsers send extra lines at the end of POST requests, and
4708 we don't want to delay sending data back to the user just because the
4709 browser isn't well behaved. [Ryan Bloom]
4711 *) Get SuEXEC working again. We can't send absolute paths to suExec
4712 because it refuses to execute those programs. SuEXEC also wasn't
4713 always recognizing configuration changes made using the autoconf
4716 *) Allow the buildconf process to find the config.m4 files in the correct
4717 order. Basically, we can now name config.m4 files as config\d\d.m4,
4718 and we will sort them correctly when inserting them into the build
4719 process. [Ryan Bloom]
4721 *) Get mod_cgid to use apr calls for creating the actual CGI process.
4722 This also allows mod_cgid to use ap_os_create_priviledged_process,
4723 thus allowing for SuExec execution from mod_cgid. Currently, we do
4724 not support everything that standard SuExec supports, but at least
4725 it works minimally now. [Ryan Bloom]
4727 *) Allow SuExec to be configured from the ./configure command line.
4730 *) Update some of the docs in README and INSTALL to reflect some of
4731 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
4733 *) If we get EAGAIN returned from the call to apr_sendfile, then we
4734 need to call sendfile again. This gets us serving large files
4735 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
4737 *) Get the support programs building cleanly again.
4738 [Cliff Woolley <cliffwoolley yahoo.com>]
4740 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
4741 current directory logic now backs up over bin/ to determine the
4742 server root from the Apache.exe path.
4744 *) Apache/Win32 now follows the standard conventions of mod_foo.so
4745 loadable modules, dynamic libs are all named libfoo.dll, and the
4746 makefile.win populates the include, lib and libexec directories.
4748 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
4749 Apache gets IPv6 listening sockets by default. Additionally, the
4750 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
4751 numeric address strings (e.g., "Listen [fe80::1]:8080").
4754 *) Modify the install directory layout. Modules are now installed in
4755 modules/. Shared libraries should be installed in libraries/, but
4756 we don't have any of those on Unix yet. All install directories
4757 are modifyable at configure time. [Ryan Bloom]
4759 *) Install all header files in the same directory on Unix. [Ryan Bloom]
4761 *) Get the functions in server/linked into the server, regardless of
4762 which modules linked into the server. This uses the same hack
4763 for Apache that we use for APR and apr-util to ensure all of the
4764 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
4765 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
4766 the scripts a bit easier.
4769 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
4770 on the query, and remove IPv4 dependencies. [Jeff Trawick]
4772 *) Get all of the auth modules to the point that they will install and
4773 be loadable into the server. Our new build/install mechanism expects
4774 that all modules will have a common name format. The auth modules
4775 didn't use that format, so we didn't install them properly.
4778 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
4779 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
4781 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
4783 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
4784 after the end of the response. [Ryan Bloom]
4786 *) Get byterange requests working with responses that do not have a
4787 content-length. Because of the way byterange requests work, we have to
4788 have all of the data before we can actually do the byterange, so we
4789 can compute the content-length in the byterange filter.
4792 *) Get exe CGI's working again on Windows.
4795 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
4796 they keep track of whether or not their post config hook has been
4797 called before. Instead of a static variable (which is replaced when
4798 the DSO is loaded a second time), use userdata in the process pool.
4801 Changes with Apache 2.0a9
4803 *) Win32 now requires perl to complete the final install step for users
4804 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
4805 and installs the conf, htdocs and htdocs/manual directories.
4808 *) Make mod_include use a hash table to associate directive tags with
4809 functions. This allows modules to implement their own SSI tags easily.
4810 The idea is simple enough, a module can insert it's own tag and function
4811 combination into a hash table provided by mod_include. While mod_include
4812 parses an SSI file, when it encounters a tag in the file, it does a
4813 hash lookup to find the function that implements that tag, and passes
4814 all of the relevant data to the function. That function is then
4815 responsible for processing the tag and handing the remaining data back
4816 to mod_include for further processing.
4817 [Paul J. Reder <rederpj raleigh.ibm.com>]
4819 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
4820 fewer parameters: the local and remote socket addresses were removed
4821 from the parameter list because all required information is available
4822 via the APR socket. [Jeff Trawick]
4824 *) Distribution directory structure reorganized to reflect a
4825 normal source distribution with external install targets.
4828 *) The MPMs that need multiple segments of shared memory now create
4829 two apr_shmem_t variables, one for each shared memory allocation.
4830 the problem is that we can't determine how much memory will be required
4831 for shared memory allocations once we try to allocate more than one
4832 variable. The MM code automatically aligns the shared memory allocations,
4833 so we end up needing to pad the amount of shared memory we want based
4834 on how many variables will be allocated out of the shared memory segment.
4835 It is just easier to create a second apr_shmem_t variable, and two
4836 shmem memory blocks.
4839 *) Cleanup the export list a bit. This creates a single unified list of
4840 functions exported by APR. The export list is generated at configure
4841 time, and that list is then used to generate the exports.c file.
4842 Because of the way the export list is generated, we only export those
4843 functions that are valid on the platform we are building on.
4846 *) Enable logging the cookie with mod_log_config
4847 [Sander van Zoest <sander covalent.net>]
4849 *) Fix a segfault in mod_info when it reaches the end of the configuration.
4852 *) Added lib/aputil/ as a placeholder for utility functions which are not
4853 specific to the Apache HTTP Server (but do not make sense with APR).
4854 The first utility is "apu_dbm": a set of functions to work with DBM
4855 files. This first version can be compiled for SDBM or GDBM databases.
4858 *) Complete re-write of mod_include. This makes mod_include a filter that
4859 uses buckets directly. This has now served the FAQ correctly.
4860 [Paul Reder <rederpj raleigh.ibm.com>]
4862 *) Allow modules to specify the first filter in a sub_request when
4863 making the sub_request. This keeps modules from having to change the
4864 output_filter immediately after creating the sub-request, and therefore
4865 skip the sub_req_output_filter. [Ryan Bloom]
4867 *) Update ab to accept URLs with IPv6 literal address strings (in the
4868 format described in RFC 2732), and to build Host header fields in
4869 the same format. This allows IPv6 literal address strings to be
4870 used with ab. This support has been tested against Apache 1.3 with
4871 the KAME patch, but Apache 2.0 does not yet work with this format
4872 of the Host header field. [Jeff Trawick]
4874 *) Accomodate an out-of-space condition in the piped logs and the
4875 rotatelogs.c code, and no longer churn log processes for this
4876 condition. [Victor J. Orlikowski]
4878 *) Add support for partial writes with apr_sendfile() to core_output_filter.
4881 Changes with Apache 2.0a8
4883 *) Add a directive to mod_mime so that filters can be associated with
4887 *) Get multi-views working again. We were setting the path_info
4888 field incorrectly if we couldn't find the specified file.
4891 *) Fix 304 processing. The core should never try to send the headers
4892 down the filter stack. Always, just setup the table in the request
4893 record, and let the header filter convert it to data that is ready
4897 *) More fixes for the proxy. There are still bugs in the proxy code,
4898 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
4902 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
4905 *) APR: Add new apr_getopt_long function to handle long options.
4906 [B. W. Fitzpatrick <fitz red-bean.com>]
4908 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
4909 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
4910 hostname resolution/address string parsing and building
4911 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
4912 of one of the apr_sockaddr_t structures for a socket. Change
4913 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
4915 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
4916 I have proxied pages with it, cleanup will commence soon.
4919 *) Make the proxy work with filters. This isn't perfect, because we
4920 aren't dealing with the headers properly. [Ryan Bloom]
4922 *) Do not send a content-length iff the C-L is 0 and this is a head
4923 request. [Ryan Bloom]
4925 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
4926 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
4928 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
4930 *) Get the default_handler to stop trying to deal with HEAD requests.
4931 The idea is to let the content-length filter compute the C-L before
4932 we try to send the data. If we can get the C-L correctly, then we
4933 should send it in the HEAD response.
4936 *) The Header filter can now determine if a body should be sent based
4937 on r->header_only. The general idea of this is that if we delay
4938 deciding to send the body, then we might be able to compute the
4939 content-length correctly, which will help caching proxies to cache
4940 our data better. Any handler that doesn't want to try to compute
4941 the content-length can just send an EOS bucket without data and
4942 everything will just work.
4945 *) Add the referer to the error log if one is available.
4946 [Markus Gyger <mgyger itr.ch>]
4948 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
4949 change, the root of the configuration tree has been exposed to modules
4951 [Ryan Morgan <rmorgan covalent.net>]
4953 *) Get the core_output_filter to use the bucket interface directly.
4954 This keeps us from calling the content-length filter multiple times
4955 for a simple static request.
4958 *) We are sending the content-type correctly now.
4959 [Ryan Bloom and Will Rowe]
4961 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
4962 a bogus bytes-sent value when the only thing being sent was trailers
4963 and writev() returned an error (or EAGAIN). [Jeff Trawick]
4965 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
4966 hints file to determine which platforms define
4967 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
4970 *) APR: add apr_get_home_directory() [Jeff Trawick]
4972 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
4974 *) Not all platforms have INADDR_NONE defined by default. Apache
4975 used to make this check and define INADDR_NONE if appropriate,
4976 but APR needs the check too, and I suspect other applications will
4977 as well. APR now defines APR_INADDR_NONE, which is always a valid
4978 value on all platforms.
4979 [Branko Èibej <brane xbc.nu>]
4981 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
4982 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
4984 *) Relax the syntax checking of Host: headers in order to support
4985 iDNS. PR#6635 [Tony Finch]
4987 *) When reading from file buckets we convert to an MMAP if it makes
4988 sense. This also simplifies the default handler because the
4989 default handler no longer needs to try to create MMAPs.
4992 *) BUFF has been removed from the main server. The BUFF code will remain
4993 in the code until it has been purged from the proxy module as well.
4996 *) Byteranges have been completely re-written to be a filter. This
4997 has been tested, and I believe it is working correctly, but it could
4998 doesn't work for the Adobe Acrobat plug-in. The output almost matches
4999 the output from 1.3, the only difference being that 1.3 includes
5000 a content-length in the response, and this does not.
5003 *) APR read/write functions and bucket read functions now operate
5004 on unsigned integers, instead of signed ones. It doesn't make
5005 any sense to use signed ints, because we return the error codes,
5006 so if we have an error we should report 0 bytes read or written.
5009 *) Always compute the content length, whether it is sent or not.
5010 The reason for this, is that it allows us to correctly report
5011 the bytes_sent when logging the request. This also simplifies
5012 content-length filter a bit, and fixes the actual byte-reporing
5013 code in mod_log_config.c
5016 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
5017 it says, because it was only used by EOS and FLUSH buckets. Since
5018 neither of those are required at the end of a brigade, this was
5019 really signifying FLUSH_THE_DATA, but that can be determined better
5020 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
5021 buckets now return a length of 0, which is actually the amount of data
5022 read, so they make more sense.
5025 *) Allow the core_output_filter to save some data past the end of a
5026 request. If we get an EOS bucket, we only send the data if it
5027 makes sense to send it. This allows us to pipeline request
5028 responses. As a part of this, we also need to allocate mmap
5029 buckets out of the connection pool, not the request pool. This
5030 allows the mmap to outlive the request.
5033 *) Make blocking and non-blocking bucket reads work correctly for
5034 sockets and pipes. These are the only bucket types that should
5035 have non-blocking reads, because the other bucket types should
5036 ALWAYS be able to return something immediately.
5039 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
5040 server, but use Ctrl+Break to initiate a graceful restart
5041 instead of duplicating behavior. [John Sterling]
5043 *) Patch mod_autoindex to set the Last-Modified header based on
5044 the directory's mtime, and add the ETag header. [William Rowe]
5046 *) Merge the 1.3 patch to add support for logging query string in
5047 such a way that "%m %U%q %H" is the same as "%r".
5050 *) Port three log methods from mod_log_config 1.3 to 2.0:
5051 CLF compliant '-' byte count, method and protocol.
5054 *) Add a new LogFormat directive, %c, that will log connection
5055 status at the end of the response as follows:
5056 'X' - connection aborted before the response completed.
5057 '+' - connection may be kept-alive by the server.
5058 '-' - connection will be closed by the server.
5061 *) Expand APR for WinNT to fully accept and return utf-8 encoded
5062 Unicode file names and paths for Win32, and tag the Content-Type
5063 from mod_autoindex to reflect that charset if the feature
5064 macro APR_HAS_UNICODE_FS is true. [William Rowe]
5066 *) Compute the content length (and add appropriate header field) for
5067 the response when no content length is available and we can't use
5068 chunked encoding. [Jeff Trawick]
5070 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
5071 so that content input filters get dechunked data when using
5072 the default handler. Also removed REQUEST_CHUNKED_PASS.
5075 *) Add mod_ext_filter as an experimental module. This module allows
5076 the administrator to use external programs as filters. Currently,
5077 only filtering of output is supported. [Jeff Trawick]
5079 *) Most Apache functions work on EBCDIC machines again, as protocol
5080 data is now translated (again). [Jeff Trawick]
5082 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
5083 the EBCDIC support. They are noops on ASCII machines, so this
5084 type of translation doesn't have to be surrounded by #ifdef
5085 CHARSET_EBCDIC. [Jeff Trawick]
5087 *) Fix mod_include. tag commands work again, and the server will
5088 send the FAQ again. This also allows mod_include to set aside
5089 buckets that include partial buckets.
5090 [Ryan Bloom and David Reid]
5092 *) Add suexec support back. [Manoj Kasichainula]
5094 *) Lingering close now uses the socket directly instead of using
5095 BUFF. This has been tested, but since all we can tell is that it
5096 doesn't fail, this needs to be really hacked on.
5099 *) Allow filters to modify headers and have those headers be sent to
5100 the client. The idea is that we have an http_header filter that
5101 actually sends the headers to the network. This removes the need
5102 for the BUFF to send headers.
5105 *) Charset translation: mod_charset_lite handles translation of
5106 request bodies. Get rid of the xlate version of ap_md5_digest()
5107 since we don't compute digests of filtered (e.g., translated)
5108 response bodies this way anymore. (Note that we don't do it at
5109 all at the present; somebody needs to write a filter to do so.)
5112 *) Input filters and ap_get_brigade() now have a input mode parameter
5113 (blocking, non-blocking, peek) instead of a length parameter.
5116 *) Update the mime.types file to the registered media types as
5117 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
5120 *) Namespace protect some macros declared in ap_config.h
5123 *) Support HTTP header line folding with input filtering.
5126 *) Mod_include works again. This should still be re-written, but at
5127 least now we can serve an SHTML page again.
5130 *) Begin to remove BUFF from the core. Currently, we keep a pointer
5131 to both the BUFF and the socket in the conn_rec. Functions that
5132 want to use the BUFF can, functions that want to use the socket,
5133 can. They point to the same place.
5136 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
5137 [Tomas "Ögren" <stric ing.umu.se>]
5139 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
5140 associated pool goes away. (APR pipes on OS/2 were already had this
5141 logic.) This resolvs a fatal file descriptor leak with CGIs.
5144 *) The final line of the config file was not being read if there was
5145 no \n at the end of it. This was caused by apr_fgets returning
5146 APR_EOF even though we had read valid data. This is solved by
5147 making cfg_getline check the buff that was returned from apr_fgets.
5148 If apr_fgets return APR_EOF, but there was data in the buf, then we
5149 return the buf, otherwise we return NULL.
5152 *) Piped logs work again in the 2.0 series.
5155 *) Restore functionality broken by the mod_rewrite security fix:
5156 rewrite map lookup keys and default values are now expanded
5157 so that the lookup can depend on the requested URI etc.
5158 PR #6671 [Tony Finch]
5160 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
5161 security bug in some mass virtual hosting configurations
5162 that can allow a remote attacker to retrieve some files
5163 on the system that should be inaccessible. [Tony Finch]
5165 *) Add a pool bucket type. This bucket is used for data allocated out
5166 of a pool. If the pool is cleaned before the bucket is destroyed, then
5167 the data is converted to a heap bucket, allowing it to survive the
5171 *) Add a flush bucket. This allows modules to signal that the filters
5172 should all flush whatever data they currently have. There is no way
5173 to actually force them to do this, so if a filter ignores this bucket,
5174 that's life, but at least we can try with this.
5177 *) Add an output filter for sub-requests. This filter just strips the
5178 EOS bucket so that we don't confuse the main request's core output
5179 filter by sending multiple EOS buckets. This change also makes sub
5180 requests start to send EOS buckets when they are finished.
5183 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
5184 makes ap_bucket_destroy a return void, which is okay because it
5185 used to always return APR_SUCCESS, and nobody ever checked its
5186 return value anyway.
5187 [Cliff Woolley <cliffwoolley yahoo.com>]
5189 *) Remove the index into the bucket-type table from the buckets
5190 structure. This has now been replaced with a pointer to the
5191 bucket_type. Also add some macros to test the bucket-type.
5194 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
5195 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
5196 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
5197 All _VAR_ flavors changes to _DATA to be absolutely clear.
5200 *) Add support for /, //, //servername and //server/sharename
5201 parsing of <Directory> blocks under Win32 and OS2.
5202 [Tim Costello, William Rowe, Brian Harvard]
5204 *) Remove the function pointers from the ap_bucket type. They have been
5205 replaced with a global table. Modules are allowed to register bucket
5206 types and use then use those buckets.
5209 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
5210 once we finish writing the request body to the cgi child process;
5211 otherwise, the client doesn't hit EOF on stdin. Small request bodies
5212 worked without this change (for reasons I don't understand), but large
5213 ones didn't. [Jeff Trawick]
5215 *) Remove file bucket specific information from the ap_bucket type.
5216 This has been moved to a file_bucket specific type that hangs off
5217 the data pointer in the ap_bucket type.
5220 *) Input filtering now has a third argument. This is the amount of data
5221 to read from lower filters. This argument can be -1, 0, or a positive
5222 number. -1 means give me all the data you have, I'll deal with it and
5223 let you know if I need more. 0 means give me one line and one line
5224 only. A positive number means I want no more than this much data.
5226 Currently, only 0 and a positive number are implemented. This allows
5227 us to remove the remaining field from the conn_rec structure, which
5231 *) Big cleanup of the input filtering. The goal is that http_filter
5232 understands two conditions, headers and body. It knows where it is
5233 based on c->remaining. If c->remaining is 0, then we are in headers,
5234 and http_filter returns a line at a time. If it is not 0, then we are
5235 in body, and http_filter returns raw data, but only up to c->remaining
5236 bytes. It can return less, but never more.
5237 [Greg Ames, Ryan Bloom, Jeff Trawick]
5239 *) mod_cgi: Write all of the request body to the child, not just what
5240 the kernel would accept on the first write. [Jeff Trawick]
5242 *) Back out the change that moved the brigade from the core_output_filters
5243 ctx to the conn_rec. Since all requests over a given connection
5244 go through the same core_output_filter, the ctx pointer has the
5248 *) Fix another bug in the send_the_file() read/write loop. A partial
5249 send by apr_send would cause unsent data in the read buffer to
5250 get clobbered. Complete making send_the_file handle partial
5251 writes to the network.
5254 *) Fix a couple of type fixes to allow compilation on AIX again
5255 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
5257 *) Fix bug in send_the_file() which causes offset to be ignored
5258 if there are no headers to send.
5261 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
5262 filter. Useful for supporting Windows 9* with a binary
5263 compiled on Windows NT.
5266 Changes with Apache 2.0a7
5268 *) Reimplement core_output_filter to buffer/save bucket brigades
5269 across multiple calls to the core_filter. The brigade will be
5270 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
5271 thresholds are hit or the EOS bucket is received.
5274 *) Create experimental filter (buffer_filter) that coalesces bytes
5275 into one large buffer before invoking the next filter in the
5276 chain. This filter is particularly useful with the current
5277 implementation of mod_autoindex when it inserted above the
5278 chunk_filter. mod_autoindex generates a lot of brigades that
5279 containing buckets holding just a few bytes each. The
5280 buffer_filter coalesces these buckets into a single large bucket.
5283 *) Add apr_sendfile() support into the core_output_filter.
5286 *) Add apr_sendv() support into the core_output_filter.
5289 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
5290 [Mike Abbott <mja sgi.com>]
5292 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
5293 make much sense, because Apache uses buckets instead of BUFFs now.
5296 *) send_the_file now falls back to a read/write loop on platforms that
5297 do not have sendfile.
5298 [Ryan Bloom and Brian Havard]
5300 *) Install apachectl correctly, and substitute the proper values so
5301 that it works again. [Ryan Bloom]
5303 *) Better(??) handle platforms that lack sendfile().
5306 *) APR now has UUID generation/formatting/parsing support.
5309 *) Begin the http_filter. This is an input filter that understands
5310 the absolute basic amount required to parse an HTTP Request. The
5311 goal is to be able to split headers from request body before passing
5312 the data back to the other filters.
5315 *) Bring forward from 1.3.13 the config directory implementation
5318 *) install apxs if it is created
5321 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
5322 conversions. [William Rowe]
5324 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
5325 ap_add_output_filter(). [Jeff Trawick]
5327 *) Multiple build and configuration fixes
5330 -add datadir and localstatedir substitutions
5332 -fix logfilename misspelling
5333 -fix evaluation of installation dir variables and
5334 -replace $foobar by $(foobar) to be usefull in the makefile
5338 -add rules for cross-compiling in rules.mk. Okay, rule to check for
5339 $CC_FOR_BUILD is still missing
5340 -use CHECK_TOOL instead of CHECK_PROG for ranlib
5341 -add missing "AR=@AR@" to severaly Makefile.in's
5342 -cache result for "struct rlimit"
5343 -compile all helper programs with native and cross compiler
5344 and use the native version to generate header file
5345 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5347 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
5349 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5351 *) Fix a bug where a client which only sends \n to delimit header
5352 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
5353 message. Start working on ebcdic co-existance with input
5355 [William Rowe, Greg Ames]
5357 *) If mod_so is enabled in the server always create libexec, even
5358 if there are no modules installed in this directory. This is a
5359 requirement for APXS to work correctly.
5362 *) Connection oriented output filters are now stored in the
5363 conn_rec instead of the request_rec. This allows us to add the
5364 output filter in the pre-connection phase instead of the
5365 post_read_request phase, which keeps us from trying to write an
5366 error page before we have a filter to write to the network.
5367 [Ryan Bloom, Jeff Trawick, and Greg Ames]
5369 *) Cleaning up an mmap bucket no longer deletes the mmap. An
5370 mmap can be used across multiple buckets (default_handler with
5371 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
5372 the mmap itself can't be associated with the bucket.
5375 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
5378 *) Radical surgery to improve mod_isapi support under Win32.
5379 Includes a number of newer ServerSupportFunction calls, support
5380 for ReadClient (in order to retrieve POSTs greater than 48KB),
5381 and general bug fixes to more reliably load ISAPI .dll's and
5382 prevent leaking handle resources. Note: There are still
5383 discrepancies between IIS's and Apache's ServerVariables, and
5384 async calls are still not supported. Additional warnings are
5385 logged to facilitate debugging of unsupported ISAPI calls.
5388 *) Add input filtering to Apache. The basic idea for the input
5389 filters is the same as the ideas for output filters. The biggest
5390 difference is that instead of calling ap_pass_brigade, ap_get_brigade
5391 should be called, and the order of execution for the filter itself is
5392 different. When writing an output filter, a brigade is passed in,
5393 and filters operate directly on that brigade, when done, they call
5394 ap_pass_brigade. Input filters are the exact opposite. Because input
5395 is not a push operation, filters first call ap_get_brigade. When this
5396 function returns, the input filter will be left with a valid brigade.
5397 The input filter should then operate on the brigade, and return.
5400 *) Fix building on BSD/OS using its native make. The build system
5401 falls back to the BSD .include directive on that host platform.
5404 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
5405 SHA1 and plaintext password encodings. Make feature tests a
5406 bit more flexible. [William Rowe]
5408 *) Charset translation: mod_charset_lite handles output content
5409 translation in a filter. mod_charset_lite no longer ignores
5410 subrequests. A bunch of cruft related to BUFF's support for
5411 translating request and response bodies was removed.
5414 *) Move the addition of the CORE filter to the post_read_request
5415 hook in http_core.c. This removes the need to add the filter in
5416 multiple places and allows for an SSL module to be added much
5417 simpler. [Ryan Bloom]
5419 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
5420 Fix a security problem that affects certain configurations of
5421 mod_rewrite. If the result of a RewriteRule is a filename that
5422 contains expansion specifiers, especially regexp backreferences
5423 $0..$9 and %0..%9, then it may be possible for an attacker to
5424 access any file on the web server. [Tony Finch]
5426 *) Fix a bug where errors that are detected during early request parsing
5427 don't produce visible HTTP error messages at the browser, because
5428 the core_filter wasn't present. [Greg Ames]
5430 *) Provide apr_socklen_t as a portability aid.
5431 [Victor J. Orlikowski]
5433 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
5434 as well as a comment arg to the add, adduser and update cmds.
5435 update allows the user to clear or preserve pw/groups/comment.
5436 Fixed a bug in dbmmanage that prevented the check option from
5437 parsing a password followed by :group... text. Corrected the
5438 seed calcualation for Win32 systems, and added -lsdbm support.
5441 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
5444 *) Avoid a segfault when parsing .htaccess files. An
5445 uninitialized tree pointer was passed to ap_build_config().
5448 *) Change the way that inet_addr & inet_network are checked for
5449 in APR's configure process to allow BeOS BONE to correctly
5450 find them. With this change BeOS BONE now builds from source
5451 with no problems. [David Reid]
5453 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
5454 the end of the parameters to execve() was stored in the wrong
5455 location, overlaying the storage beyond the newargs[] array and
5456 also passing uninitialized storage to execve(), which would
5457 sometimes fail with EFAULT. [Jeff Trawick]
5459 *) Fix a bug parsing configuration file containers. With a sequence
5460 like this in the config file
5462 <IfModule mod_kilroy.c>
5465 <IfModule mod_lovejoy.c>
5470 the second container would be terminated at the blank line due to
5471 sediment in the buffer from reading the prior </IfModule> and an
5472 error message would be generated for the real </IfModule> for the
5473 second container. Also due to this problem, any two characters
5474 could be used for "</" in the close of a container.
5477 *) ap_add_filter prototype changed to remove the ctx pointer. The
5478 pointer still remains in the filter structure, but it can not be
5479 a part of the ap_add_filter prototype. The reason is that when
5480 the core uses AddFilter to add a filter to the stack it doesn't
5481 know how to allocate the ctx pointer, or even how much memory should
5482 be allocated. The filters will have to be responsible for allocating
5483 the ctx memory when they need it.
5486 *) Add an AddFilter directive. This directive takes a list of filters
5487 that should be activated for the requested resource.
5490 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
5491 some other platforms). [Jeff Trawick]
5493 *) Modify mod_include to be a filter. Currently, it has only been tested
5494 on actual files, but it should work for CGI scripts too.
5497 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
5498 writes. apr_flush() for Unix: handle interrupted writes.
5501 *) NameVirtualHost can now take "*" as an argument instead of
5502 an IP address. This allows you to create a purely name-based
5503 virtual hosting server that does not have any IP addresses in
5504 the configuration file and which ignores the local address
5505 of any connections. PR #5595, PR #4455 [Tony Finch]
5507 *) Fix some compile warnings in mod_mmap_static.c
5508 [Mike Abbott <mja sgi.com>]
5510 *) Fix chunking problem with CGI scripts. The general problem was that
5511 the CGI modules were adding an EOS bucket and then the core added an
5512 EOS bucket. The chunking filter finalizes the chunked response when it
5513 encounters an EOS bucket. Because two EOS buckets were sent, we
5514 finalized the response twice. The fix is to make sure we only send one
5515 EOS, by utilizing a flag in the request_rec.
5518 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
5519 and Win32. Previously, the first read from an apr_file_t set up via
5520 apr_put_os_file() would return a '\0'. [Jeff Trawick]
5522 *) Mod_cgid now creates a single element bucket brigade, with a pipe
5523 bucket, instead of using BUFF's and ap_r*.
5526 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
5527 [Mike Abbott <mja sgi.com>]
5529 *) Remove ap_bopenf from buff code. This required modifying the file_cache
5530 code to use APR file's directly instead of going through BUFFs.
5533 *) Fix compile break on some platforms for mod_mime_magic.c
5534 [John K. Sterling <sterling covalent.net>]
5536 *) Fix merging of AddDefaultCharset directive.
5537 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
5539 *) Minor revamp of the rlimit sections of code. We now test
5540 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
5541 is now "available" even if the platform doesn't support
5542 the rlimit family (it's just a noop though). [Jim Jagielski]
5544 *) Migrate the pre-selection of which MPM to use for specific
5545 platforms to hints.m4, which contains (or should contain)
5546 all platform specific "hints". [Jim Jagielski]
5548 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
5551 *) Add tables with non-string/binary values to APR.
5554 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
5557 *) Update PCRE to version 3.2. [Ryan Bloom]
5559 *) Change the way buckets' destroy functions are called so that
5560 they can be more directly used when changing the type of a
5561 bucket in place. [Tony Finch]
5563 *) Add generic support for reference-counting the resources used by
5564 buckets, and alter the HEAP and MMAP buckets to use it. Change
5565 the way buckets are initialised to support changing the type of
5566 buckets in place, and use it when setting aside TRANSIENT buckets.
5567 Change the implementation of TRANSIENT buckets so that it can be
5568 mostly shared with IMMORTAL buckets, which are now implemented.
5571 Changes with Apache 2.0a6
5573 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
5575 *) Add a chunking filter to Apache. This brings us one step closer
5576 to removing BUFF. [Ryan Bloom]
5578 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
5579 added to the stack is the last filter to be called. [Ryan Bloom]
5581 *) Apache 2.0 has been completely documented using Scandoc. The
5582 docs can be generated by running 'make docs'. [Ryan Bloom]
5584 *) Add filtered I/O to Apache. This is based on bucket brigades,
5585 Currently the buckets still use BUFF under the covers, but that
5586 should change quickly. The only currently written filter is the
5587 core filter which just calls ap_bwrite. [The Apache Group]
5589 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
5590 built with thread support. [Jeff Trawick]
5592 *) Abort configuration if --with-layout was specified and there's
5593 no layout definition file. [Ken Coar]
5595 *) Add support for '--with-port=n' option to configure. [Ken Coar]
5597 *) Add support for extension methods for the Allow response header
5598 field, and an API routine for accessing r->allowed and the
5599 list of extension methods in a unified manner. [Ken Coar]
5601 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5602 [Rob Simonson <simo us.ibm.com>]
5604 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5605 APACHE_XLATE builds. [Jeff Trawick]
5607 *) A configuration file parsing problem was fixed. When the
5608 configuration file started with an IfModule/IfDefine container,
5609 only the last statement in the container would be retained.
5612 Changes with Apache 2.0a5
5614 *) Perchild is serving pages after passing them to different child
5615 processes. There are still a lot of bugs, but this does work. I
5616 have made requests against the same installation of Apache, and had
5617 different servers use different user IDs to serve the responses.
5618 This change moves to using socketpair instead of an AF_UNIX socket.
5621 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5622 It can't seem to pass between child processes yet, but I think we
5623 are closer now than before. This moves us back to using Unix
5624 Domain Sockets. [Ryan Bloom]
5626 *) libapr functions and types renamed with apr_ prefix.
5627 #include "apr_compat.h" for 1.3.x backwards compat
5630 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5631 return the right information on the local socket address.
5632 [Gregory Nicholls <gnicholls level8.com>]
5634 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5635 [Gregory Nicholls <gnicholls level8.com>]
5637 *) Add an option to not detach from the controlling terminal without
5638 going into single process mode. This allows for much easier
5639 debugging of the process startup code. [Ryan Bloom]
5641 *) ab: don't use perror() to report the failure of an APR function.
5644 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5645 scoreboard on graceful restarts.
5648 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5649 An invalid ap_proc_t was passed to ap_create_process().
5652 *) Allow modules to register filters. Those filters are still
5653 never called, but this is a step in the right direction.
5654 [Ryan Bloom and Greg Stein]
5656 *) Register the mod_cgid daemon process for cleanup so that it is
5657 killed at termination if it does not die when the parent gets
5658 SIGTERM. This change is to fix occasional problems where the
5659 process stays around. Bugs in similar logic in mod_rewrite and
5660 mod_include were also fixed. [Jeff Trawick]
5662 *) Fix a bug in the time handling. Basically, we were imploding a time
5663 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5664 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5665 uses those two fields to adjust the time value. Because of the HTTP
5666 spec, both of those values can be zero'ed out safely. This fixes
5667 the bug correctly. [Ryan Bloom]
5669 *) Fix a couple of place in the Windows code where the wrong error
5670 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
5672 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5674 *) Added the APR_EOL_STR macro for platform dependent differences in
5675 logfiles and other raw text (such as all APR files). Fixes logfiles
5676 not terminated with cr/lf sequences in Win32. [William Rowe]
5678 *) Move all strings functions in APR to src/lib/apr/strings and create
5679 apr_strings.h for the prototypes. [Ryan Bloom]
5681 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5682 to repeat the syscall until we stop getting EINTR. I noticed a
5683 related problem at termination (SIGTERM) on FreeBSD when using
5684 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5685 implementation work properly with child init. Previously, ap_lock()
5686 was essentially a no-op because all children were using different
5687 locks and thus nobody ever blocked. [Jeff Trawick]
5689 *) The htdocs/ tree has been moved out of the CVS source tree into
5690 a separate area for easier development. This has NO EFFECT on
5691 end-users or Apache installations. [Ken Coar]
5693 *) Integrate the mod_dav module for WebDAV protocol handling. This
5694 adds the dav and dav_fs modules, the SDBM library, and additional
5695 XML handling utilities. [Greg Stein]
5697 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
5700 *) Update the lib/expat-lite/ library (bring forward changes from
5701 the Apache 1.3 repository). [Greg Stein]
5703 *) If sizeof(long long) == sizeof(long), then prefer long in APR
5704 configure.in. [Dave Hill <ddhill zk3.dec.com>]
5706 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
5707 machines where sendfile is detected, but nobody has written ap_sendfile.
5708 [Dave Hill <ddhill zk3.dec.com>]
5710 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
5712 *) ab would start up more connections than needed, then quit when the
5713 desired number were finished. Also fixed a logic error involving
5714 ab keepalives. [Victor J. Orlikowski]
5716 *) WinNT: Implement non-blocking pipes with timeouts to communicate
5717 with CGIs. Apache 2.0a4 had non-blocking pipes but without
5718 timeouts (i.e, if a timeout was specified, the pipe reverted to
5719 a full blocking pipe). Now the behaviour is more in line with
5720 Unix non-blocking pipes.
5723 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
5724 cache open file handles along with accept socket reuse enables
5725 Apache 2.0 to serve non-keepalive requests for static files at
5726 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
5727 and Apache 2.0 will serve almost 1200 rps on my system).
5730 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
5731 supports two config directives, mmapfile (same behavious as
5732 mod_mmap_static) and cachefile. Use the cachefile directive
5733 to cache open file handles. This directive only works on systems
5734 that have implemented the ap_sendfile API. cachefile works today
5735 on Windows NT, but has not been tested on any flavors of Unix.
5738 *) Cleanup the configuration. With the last few changes the
5739 configuration process automatically:
5740 inherits information about how to build from APR. Allowing
5741 APR to inform Apache that it should or should not use -ldl
5743 Detects which mod_cgi should be used mod_cgi or mod_cgid,
5744 based on the threading model
5746 Apache calls APR's configure process before finishing it's
5747 configuration processing, allowing for more information flow
5752 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
5753 with non-zero argument makes the socket non-blocking. BeOS and
5754 OS/2 already worked this way. [Jeff Trawick]
5756 *) ap_close() now calls ap_flush() for buffered files, so write
5757 operations work a whole lot better on buffered files.
5760 *) Fix error messages issued from MPMs which explain where to change
5761 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
5764 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
5765 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
5766 now the way that the blocking state of a pipe is manipulated.
5767 ap_block_pipe() is gone. [Jeff Trawick]
5769 *) Correct the problem where the only local host name that the IP stack
5770 can discover are 'undotted' private names. If no fully qualified
5771 domain name can be identified, the default ServerName will be set to
5772 the machine's IP address string. A warning is always provided if the
5773 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
5775 *) Repair problems with config file processing which caused segfault
5776 at init when virtual hosts were defined and which caused ServerName to
5777 be ignored when there was no valid DNS setup. [Jeff Trawick]
5779 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
5781 *) Add ap_sendfile implementation for AIX
5782 [Victor J. Orlikowski]
5784 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
5785 apr_network_io.h, and apr_thread_proc.h.
5786 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
5788 *) Bring the allocation and pool debugging code back into a working
5789 state. This will need to be tested as so far it's only been used on
5792 *) Change configuration command setup to be properly typesafe when in
5793 maintainer mode. Note that this requires a compiler that can initialise
5794 unions. [Ben Laurie]
5796 *) Turn on buffering for config file reads. Part of this was to
5797 repair buffered I/O support in Unix and implement buffered
5798 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
5800 *) Win32: Fix problem where UTC offset was not being set correctly
5801 in the access log. Problem reported on news group by Jerry Baker.
5804 *) Fix segfault when reporting this type of syntax error:
5805 "</container> without matching <container> section", where
5806 container is VirtualHost or Directory or whatever.
5809 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
5810 Prevent the source code for CGIs from being revealed when
5811 using mod_vhost_alias and the CGI directory is under the document root
5812 and a user makes a request like http://www.example.com//cgi-bin/cgi
5813 as reported in <news:960999105.344321 ernani.logica.co.uk>
5816 *) Add support for the new Beos NetwOrking Environment (BONE)
5819 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
5820 final input char is incomplete; ap_bwrite_xlate() now handles
5821 incomplete final input chars. [Jeff Trawick]
5823 *) Yet another update to saferead/halfduplex stuff -- need to ensure
5824 that a bhalfduplex call occurs before logging or else DNS and
5825 such can delay the last packet of the response. [Dean Gaudet]
5827 *) Some syscall reduction in APR on unix -- don't seek when setting
5828 up an mmap; and don't fcntl() more than once per socket.
5831 *) When mod_cgid is started as root, the cgi daemon now switches
5832 to the configured User/Group (like other httpd processes)
5833 instead of continuing as root. [Jeff Trawick]
5835 *) The prefork MPM now uses an APR lock for the accept() mutex.
5836 It has not been getting a lock at all recently. httpd -V now
5837 displays APR's selection of the lock mechanism instead of the
5838 symbols previously respected by prefork. [Jeff Trawick]
5840 *) Change the mmap() feature test to check only for existence.
5841 The previous check required features not used by Apache.
5844 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
5845 sometimes mangled. The len parm to accept() was not
5846 initialized, leading sometimes to an endless loop of failed
5847 accept() calls on OS/390 and anywhere else that failed the call
5848 if the len was negative. Use <sys/un.h> for struct sockaddr_un
5849 instead of declaring it ourselves to fix a compilation problem
5850 on Solaris. [Jeff Trawick]
5852 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
5854 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
5856 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
5858 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
5859 initialization if ALLOC_DEBUG is defined; no known symptom
5860 otherwise. [Jeff Trawick]
5862 *) Fix typo in configure script when checking for mod_so. bash
5863 doesn't seem to have a problem but /bin/sh on Solaris does.
5864 Symptom: "./configure: test: unknown operator =="
5867 *) Rebind the Win32 NT and 9x services control into the MPM.
5868 All console, WinNT SCM and Win9x pseudo-service control code is
5869 now wrapped within the WinNT MPM.
5872 *) Make a copy of getenv("PATH") before storing for later use. Some
5873 getenv() implementations use the same storage for successive calls.
5874 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
5876 *) Server Tokens work in 2.0 again. This also propogates the change
5877 to allow just the product name in the server string using
5881 Changes with Apache 2.0a4
5883 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
5884 won't need to call it. [Greg Ames, Jeff Trawick]
5886 *) Move pre_config hook call to between configuration read and config
5887 tree walk. This allows all modules to implement pre_config hooks
5888 and know that they will be called at an appropriate time.
5891 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
5894 *) Add pre-config hooks back to all modules.
5897 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
5898 ContentDigest enabled and we can't/don't mmap the file.
5901 *) We now report the correct line number for syntax errors in config
5902 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
5904 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
5905 related bugs, and changed shmem/locking to use apr API. Shared-mem
5906 is currently disabled, however, because of problems with graceful
5907 restarts. [Ronald Tschalär]
5909 *) Fix corruption of IFS variable in --with-module= handling.
5910 Depending on the user's shell or customization thereof, there
5911 would be errors generating ap_config_auto.h later in the configure
5912 procedure. [Jeff Trawick]
5914 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
5915 isn't used (as in 1.3), except that on Unix it is now logged via
5916 ap_log_rerror() instead of by the child having STDERR_FILENO refer
5917 to the error log. [Greg Ames, Jeff Trawick]
5919 *) Add '-D' argument processing for run time configuration defines.
5922 *) Organize http_main.c as independent code, such that no code or
5923 global data is exported from it. WIN32 will dynamically link it
5924 to the server core, so this will prevent mutual dependency.
5927 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
5928 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
5931 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
5932 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
5934 *) Add mod_charset_lite for configuring character set translation.
5937 *) Add '-n' option to htpasswd to make it print its user:pw record
5938 on stdout rather than having to frob a text file. [Ken Coar]
5940 *) Fix saferead. Basically, we flush the output buffer if a read on the
5944 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
5945 a conversion is single-byte only. [Jeff Trawick]
5947 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
5948 the BeOS 5.0 documentation says that shutdown doesn't work yet.
5951 *) Fix some minor errors where pid was being manipulated as an int
5952 instead of the portable pid_t. [Roy Fielding]
5954 *) Fix some error log prints that were printing the pointer to a
5955 structure rather than the pid within the structure.
5956 [Jeff Trawick, Roy Fielding]
5958 *) ab: Fix a command-line processing bug; track bad headers in
5959 err_response; support reading headers up to 2K.
5960 [Ask Bjoern Hansen <ask valueclick.com>]
5962 *) Fix ap_resolve_env() so that it handles new function added in a prior
5963 alpha (see "Added the capability to do ${ENVVAR} constructs in the
5964 config file.") as well as the constructs used by mod_rewrite.
5965 [Paul Reder <rederpj raleigh.ibm.com>]
5967 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
5969 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
5970 APR to perform translation, instead of accessing the hard-coded tables
5971 in 1.3's ebcdic.c. [Jeff Trawick]
5973 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
5976 *) Add the ability to hook into the config file reading phase. Basically
5977 if a directive is specified EXEC_ON_READ, then when that directive is
5978 read from the config file, the assocaited function is executed. This
5979 should only be used for those directives that must muck with HOW the
5980 server INTERPRETS the config. This should not be used for directives
5981 that re-order or replace items in the config tree. Those changes should
5982 be made in the pre-config step.
5985 *) Add mod_example to the build system.
5988 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
5989 byte character sets. [Jeff Trawick]
5991 *) Pick up various EBCDIC fixes from 1.3 (from Martin
5992 Kraemer and Oliver Reh originally according to the change log).
5995 *) Fix a couple of problems in RFC1413 support (controlled by the
5996 IdentityCheck directive). Apache did not build the request string
5997 properly and more importantly Apache would loop forever if the
5998 would-be ident server dropped the connection before sending a
5999 properly terminated response. [Jeff Trawick]
6001 *) apxs works in 2.0.
6004 *) Reliable piped logs work in 2.0.
6007 *) Introduce a hash table implementation into APR to be used for
6008 replacing tables and other random data structures in Apache.
6011 *) Add some more error reporting to htpasswd in the case of problems
6012 generating or accessing the temporary file. Also, pass in a
6013 buffer if the implementation knows how to use it (i.e., if L_tmpnam
6014 is defined). [Ken Coar]
6016 *) Configure creates config.nice now containing your configure
6017 options. Syntax: ./config.nice [--more-options]
6020 *) Fix various return code problems in APR on Win32. For most of
6021 these, APR was returning APR_EEXIST instead of GetLastError()/
6022 WSAGetLastError(). [Jeff Trawick]
6024 *) Make piped logs work again in version 2.0
6027 *) Add VPATH support to UNIX build system of Apache and APR.
6030 *) Fix ap_tokenize_to_argv to respect the const arguments that are
6034 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
6035 Patch submitted to author.
6038 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
6039 /sbin in PATH on FreeBSD (all submitted to rse previously)
6042 *) Fix building Pthread-based MPMs on OpenBSD
6043 [Sascha Schumann] PR#26
6045 *) Fix ap_readdir() problem on systems where d_name[] field in
6046 struct dirent is declared with only one byte. (This problem only
6047 affected multithreaded builds.) This caused a segfault during
6048 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
6049 least). [Jeff Trawick]
6051 *) Fix some make-portability problems on at least Tru64, Irix
6053 [Sascha Schumann] PR#18, PR#39
6055 *) Add ap_sigwait() to support old-style sigwait() on systems
6056 like OS/390 and UnixWare.
6059 *) Add POSIX-thread flags for more platforms.
6062 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
6063 (on Unix, at least) to handle resolver errors. Fix a bug in
6064 the definition of APR_ENOMEM so that ap_strerror() can spit
6065 out the correct error message for it.
6068 Changes with Apache 2.0a3
6070 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
6073 *) API: *HOOK* macros now have an AP_ prefix
6076 *) Win32: Eliminate redundant calls to initialize winsock.
6077 [Tim Costello <timcostello ozemail.com.au>]
6079 *) Fix bugs initializing ungetchar for pipes.
6080 [Chia-liang Kao <clkao CirX.ORG>]
6082 *) The ab program in the src/support directory is now portable using
6086 *) Support directory is being compiled when the server is built
6089 *) The configure option --with-program-name has been added to allow
6090 developers to rename the executable at configure time. This also
6091 changes the name of the config files to match the executable's name.
6094 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
6095 containing version numbers. [Martin Pool]
6097 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
6098 Unix; access_log and error_log now created with these perms; non-
6099 Unix is unaffected [Jeff Trawick]
6101 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
6102 Replaced more magic numbers with MD5_DIGESTSIZE.
6103 [William Rowe, Roy Fielding]
6105 *) Win32: Get mod_auth_digest compiling and added to the Windows
6106 build environment. Not tested and I'd be suprised if it
6107 actually works. [Bill Stoddard]
6109 *) Revamp the Win32 make environment. Makefiles have been removed and
6110 Apache.dsw created to bring together all the pieces. Create new file
6111 os/win32/BaseAddr.ref to define module base addresses (to prevent
6112 dll relocation at start-up).
6113 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
6115 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
6116 of the \015, \012, and \015\012 constants with macros.
6119 *) Add ap_xlate_open() et al for translation of text between different
6120 character sets. The initial implementation requires iconv().
6123 *) More FAQs and answers from comp.infosystems.www.servers.unix.
6124 [Joshua Slive <slive finance.commerce.ubc.ca>]
6126 *) CGI output is being timed out now.
6129 *) Fix the problem with dieing quietly. dupfile now takes a pool which
6130 is used by the new apr file. There is no reason to create a new file
6131 with the same lifetime as the original file.
6134 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
6135 module base addresses. This will help shooting seg faults
6136 in the field. [William Rowe <wrowe lnd.com>]
6138 *) Update Apache on Windows documentation. Add new document
6139 describing how to compile Apache on Windows.
6140 [William Rowe <wrowe lnd.com>]
6142 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
6143 microseconds instead of seconds. Some storage leaks and other
6144 minor bugs in related code were fixed. [Jeff Trawick]
6146 *) Win32: First cut at getting mod_isapi working under 2.0
6147 [William Rowe <wrowe lnd.com>]
6149 *) First stab at getting mod_auth_digest working under 2.0
6150 quick change summary:
6151 - moved the random byte generation (ap_generate_random_bytes) into APR
6152 - now uses ap_time_t
6153 - compiles and runs on linux
6155 [Brian Martin <bmartin penguincomputing.com>]
6157 *) Win32: Move the space stripping of physical service names
6158 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
6159 unresolved symbol. Add dependency checking to the
6160 CreateService call to ensure TCPIP and AFP (winsock) is started
6162 [William Rowe <wrowe lnd.com>]
6164 *) Win32: Add code to perform latebinding on functions that may
6165 not exist on all levels of Windows where Apache runs. This
6166 is needed to allow Apache to start-up on Win95/98. All calls
6167 to non portable functions should be protected with
6168 ap_oslevel checks to prevent runtime segfaults.
6169 [William Rowe <wrowe lnd.com>]
6171 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
6173 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
6175 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
6176 This addresses PR 1623. Still need to address timing out runaway
6177 CGI scripts. [Bill Stoddard]
6179 *) Win32: Make ap_stat Windows 95/98 friendly
6180 [William Rowe <wrowe lnd.com>]
6182 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
6183 always fail. Need to initialise the dwOSVersionInfoSize member of the
6184 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
6187 The patch also enhances ap_get_oslevel (and the associated enum) to
6188 handle selected service packs for NT4, and adds recognition for
6189 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
6190 we can use ReadFileScatter and WriteFileGather in readwrite.c.
6191 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
6193 *) Get mod_rewrite building and running, and mod_status building for Win NT
6194 [Allan Edwards <ake raleigh.ibm.com>]
6196 *) Patch to port mod_auth_db to the 2.0 api and also to support
6197 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
6198 2.7.7. It should work with version 1 as well but I haven't tested it.
6199 [Brian Martin <bmartin penguincomputing.com>]
6201 *) Get APR DSO code working under Windows. Includes cross platform
6203 [<Tim.Costello BTFinancialgroup.com>]
6205 *) Fix some of the Windows APR time functions.
6208 *) FAQ changes related to tidying up historical documents on the web site.
6209 [Joshua Slive <slive finance.commerce.ubc.ca>]
6211 *) Move Windows DSO code into APR.
6214 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
6215 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
6216 at build time. At this point, the server will not compile on Windows because
6217 of the recent DSO commits. Fixing those next.
6218 [Bill Rowe & Bill Stoddard]
6220 *) Added error checking for file I/O APR routines.
6221 [Jon Travis <jtravis covalent.net>]
6223 *) APR: Don't use the values of resolver error codes for the
6224 corresponding APR error codes. On Unix and Win32, return the
6225 proper APR error code after a resolver error. [Jeff Trawick]
6227 Changes with Apache 2.0a2
6229 *) Renamed the executable back to httpd on all platforms other
6233 *) Allow BeOS to survive restarts, log properly and a few
6234 small things it had problems with due to the way it setup
6235 users and groups. [David Reid]
6237 *) Get mod_rewrite working with APR locks
6238 [Paul Reder <rederpj raleigh.ibm.com>]
6240 *) Actually remove the sempahore when the lock cleanup routine
6241 is called on BeOS. [David Reid]
6243 *) Clear hook registrations between reads of the config file.
6244 When DSOs are unloaded and re-loaded the old hook pointers may
6245 no longer be valid. This fix eliminates potential segfaults.
6246 [Allan Edwards <ake raleigh.ibm.com>]
6248 *) Fix a problem with Sigfunc not being defined or bypassed
6249 if sigaction() wasn't found. [Jim Jagielski]
6251 *) Fix the locking mechanism on BSD variants. They now use fcntl
6252 locks. This allows the server to start and serve pages.
6255 *) First cut at getting the Win32 installer to work
6256 [William Rowe <wrowe lnd.com>]
6258 *) Get htpasswd compiling under Windows
6259 [William Rowe <wrowe lnd.com>]
6261 *) Change the log message for a bind() failure to show the
6262 interface and port number. [Jeff Trawick]
6264 *) Import the documentation from 1.3.12 and bring parts of it
6265 up-to-date with respect to the changes that have occurred
6269 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
6270 now logged correctly on BeOS.
6273 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
6274 Makefile.win includes the same user interface as the old
6276 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
6278 *) Win32 exec now uses COMSPEC environment string for command
6279 shell path resolution.
6280 [William Rowe <wrowe lnd.com>] PR#3715
6282 *) Win32: ap_connect() was not returning correct error condition
6284 [Allen Prescott <allen clanprescott.com>]
6286 *) Win32: ap_open() was broken on Win9x because an NT-specific
6287 flag was passed to CreateFile. ap_puts() added an unnecessary
6289 [Jeff Trawick <trawick us.ibm.com>]
6291 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
6292 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
6293 confusing ee/et name and made all extensions language/dialect
6294 rather than country reflecting. Changed example files to
6295 explicit reflect the ISO charset and added a few common
6296 ones to the example config [dirkx]
6298 *) Extend external module capability. To use this, you call
6299 configure with --with-module=path/to/mod1,path/to/mod2,etc.
6302 *) Backported the various "default charset" fixes from 1.3.12,
6303 including the AddDefaultCharset directive. [Jim Jagielski]
6305 *) Added the capability to do ${ENVVAR} constructs in the
6306 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
6307 it does this on a line by line basis; i.e. if the envvar
6308 expands to something with spaces you have to protect it
6309 by adding quotes around it (Unless of course you expect it
6310 to contains more than one argument. Alternatively you
6311 can compile it on a per token basis; which is what people
6312 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
6313 hampers fancier hacks.
6314 [Dirk-Willem van Gulik]
6316 *) Changed the 'ErrorDocument' syntax in that it NO longer
6317 supports the asymetric
6319 ErrorDocument 301 "Some message
6321 Note the opening " quote, without a closing quote. It now
6322 has either the following syntaxes
6324 ErrorDocument XXX /local/uri
6325 ErrorDocument XXX http://valid/url
6326 ErrorDocument XXX "Some Message"
6328 The recognition heuristic is: if it has a space it
6329 is a message. If it has no spaces and starts with a /
6330 or is a valid URL then treat it that way. Otherwise it
6331 is assumed to be a message.
6333 This breaks backward compatibility but makes live a hell
6334 of a lot easier for GUI's and config file parsers.
6335 [Dirk-Willem van Gulik]
6337 *) Changed 'CacheNegotiatedDocs' from its present/not-present
6338 syntax into a 'on' or 'off' syntax. As it currently is the
6339 only non nesting token which uses NO_ARGS and thus is an
6340 absolute pain for any config interface automation. This
6341 breaks backward compatibility. [Dirk-Willem van Gulik]
6343 *) Add ability to add external modules to the build process. This is
6344 done with --with-module=/path/to/module. Modules can only be added
6345 as static modules at this point.
6348 Changes with Apache 2.0a1
6350 *) Fix FreeBSD 3.3 core dump.
6351 Basically, ap_initialize() needs to get called before
6352 create_process(), since create_process() passes op_on structure
6353 to semop() to get a lock, but op_on isn't initialized until
6354 ap_initialize() calls setup_lock(). Here is a slight
6355 rearrangement to main() which calls ap_initialize() earlier...
6356 [Jeff Trawick <trawick us.ibm.com>]
6358 *) Enable Apache to use sendfile/TransmitFile API
6359 [Bill Stoddard, David Reid, Paul Reder]
6361 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
6365 *) Make file I/O and network I/O writev/sendv APIs consistent.
6366 Eliminate use of ap_iovec_t and use Posix struct iovec.
6367 Use seperate variable on ap_writev to set the number of iovecs
6368 passed in and number of bytes written.
6371 *) Adapt file iol to use APR functions. Replaced ap_open_file()
6372 with ap_create_file_iol(). ap_create_file_iol() requires that
6373 the file be opened prior to the call using ap_open().
6376 *) Port mod_include and mod_cgi to 2.0
6377 [Paul Reder, Bill Stoddard]
6379 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
6380 bytes_read/bytes_written is always valid (never -1). Plus
6381 some fixes to buff.c to correct problems introduced by the
6382 errno => ap_status_t changes a while back. Plus a fix to
6383 chunked encoding introduced right at the beginning of 2.0.
6386 *) Revamped UNIX build system to use autoconf and libtool.
6387 [Manoj Kasichainula, Sascha Schumann]
6389 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
6391 *) SECURITY: More rigorous checking of Host: headers to fix security
6392 problems with mass name-based virtual hosting (whether using mod_rewrite
6393 or mod_vhost_alias).
6394 [Ben Hyde, Tony Finch]
6396 *) Add back support for UseCanonicalName in <Directory> containers.
6397 [Manoj Kasichainula]
6399 *) Added APLOG_STARTUP log type. This allows us to write an error
6400 message without any of the date and time information. As a part
6401 of this change, I also removed all of the calls to fprintf(stderr
6402 and replaced them with calls to ap_log_error using APLOG_STARTUP
6403 writing to stderr is no longer portable, because we don't direct
6404 stderr to the error log on all platforms.
6407 *) Convert error logging functions to take errno as an argument.
6408 This makes our error logs more portable, because some Windows API's
6409 don't set errno. This change allows us to still output a valid
6410 message on all of our platforms.
6413 *) mod_mime_magic runs in 2.0-dev now.
6414 [Paul Reder <rederpj raleigh.ibm.com>]
6416 *) sendfile has been added to APR.
6417 [John Zedlewski <zedlwski Princeton.EDU>]
6419 *) buff.c has been converted to no longer use errno.
6420 [Manoj Kasichainula]
6422 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
6423 interface adaption to APR functions did it. [Martin Kraemer]
6425 *) Support DSOs properly on 32-bit HP-UX 11.0
6426 [Dilip Khandekar <dilip cup.hp.com>]
6428 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
6429 [Ralf S. Engelschall]
6431 *) Cleaned APR build environment integration and bootstrap APR
6432 automatically for developers from src/Configure.
6433 [Ralf S. Engelschall]
6435 *) Fixed building of src/support/htpasswd.c
6436 [Ralf S. Engelschall]
6438 *) When generating the Location: header, mod_speling forgot
6439 to escape the spelling-fixed uri. (Forw-Port from 1.3)
6442 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
6444 *) Change all pools to APR contexts. This is the first step to
6445 incorporating APR into Apache. [Ryan Bloom]
6447 *) Move "handler not found" warning message to below the check
6448 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
6449 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
6451 *) Support line-continuation feature in config.option file and
6452 allow the loading of multiple option sections at once via
6453 ``--with-option=<section1>,<section2>,...''
6454 [Ralf S. Engelschall]
6456 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
6458 Changes with Apache MPM
6460 *) Use asynchronous AcceptEx() and a completion port to accept and
6461 dispatch connections to threads in Windows NT/2000.
6464 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
6467 *) Implement the APACI --with-option facility
6468 (per default used the config.option file).
6469 [Ralf S. Engelschall]
6471 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
6473 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
6474 Replace pre_connection module call with a register_hook call and
6475 implement pre_connection as a hook. The intent is that these hooks will
6476 be extended to allow Apache to be multi-protocol, and also to allow the
6477 calling order to be specified on a per-hook/per-module basis.
6480 *) Implement mpm_* methods as "modules". Each method gets its own
6481 subdir in src/modules (eg: src/modules/prefork). Selection
6482 of method uses Rule MPM_METHOD. [Jim Jagielski]
6484 *) Port the hybrid server from the apache-apr repository as
6485 mpm_mpmt_pthread. [Manoj Kasichainula]
6487 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
6488 amongst the unix MPMs.
6490 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
6491 signal handling for the new world order. [Dean Gaudet]
6493 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
6494 of alloc.c for now. [Dean Gaudet]
6496 *) Handle partial large writes correctly. [Ben Laurie]
6498 *) Eliminate conn_rec's pointer to server. All it knows is the base server
6499 based on IP/port. [Ben Laurie]
6501 *) Port a bunch of modules to the new module structure.
6502 ["Michael H. Voase" <mvoase midcoast.com.au>]
6504 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
6506 *) Basic restructuring to introduce the MPM concept; includes various
6507 changes to the module API... better described by
6508 docs/initial_blurb.txt. [Dean Gaudet]
6510 Changes with Apache pthreads
6512 *) New buff option added: BO_TIMEOUT. It describes the timeout for
6513 buff operations (generally over a network).
6514 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
6516 *) Created http_accept abstraction. Added 4 new functions (not exported):
6517 init_accept(), begin_accepting_requests(), get_request(),
6518 stop_accepting_requests() [Bill Stoddard]
6520 *) Fix to ap_rprintf call that allows mod_info to work properly.
6521 [James Morris <jmorris intercode.com.au>]
6523 *) user and ap_auth_type fields were moved from connection_rec to
6524 request_rec. [Ryan Bloom]
6526 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
6527 needed in a threaded server.
6529 *) Initial pthread implementation from from Dean's apache-nspr code.
6530 [Bill Stoddard, Ryan Bloom]
6533 Changes with Apache 1.3.9
6535 *) Remove bogus error message when a redirect doesn't set Location.
6536 Instead, use an empty string to avoid coredump if the error message
6537 was supposed to include a location. [Roy Fielding]
6539 *) Don't allow configure to include mod_auth_digest unless it is
6540 explicitly requested, even if the user asked for all modules.
6543 *) Translate module names to dll names for OS/2 so that they are no more
6544 than 8 characters long and have an extension of "dll" instead of "so".
6547 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
6548 Fix test-compile check to check for randbyte instead of trand32.
6549 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
6550 and tweak to make Amaya happier. [Ronald Tschalär]
6552 *) Ensure that the installed expat include files are world readable,
6553 just like the other header files. [Martin Kraemer]
6555 *) Fixed generated AddModule adjustments in APACI's `configure' script
6556 in order to allow (new) modules like mod_vhost_alias to be handled
6557 correctly (which was touched by the adjustments for mod_alias).
6558 [Ralf S. Engelschall]
6560 *) For binary builds, add -R flag to apachectl to work around the lack of
6561 an absolute path to the ./libexec directory where the libhttp.ep file
6562 is needed for SHARED_CORE architectures. [Randy Terbush]
6564 *) WIN32: Create the CGI script process as DETACHED. This may solve the
6565 problem observed by some Win95/98 users where they get CGI script
6566 output sent to the console. [Bill Stoddard]
6568 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
6569 routines are now called ap_base64* and are 'plain' (i.e., no
6570 pool access or anything clever). Inside util.c the routines acting
6571 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
6572 The oddly named ap_uuencode(), ap_uudecode() are kept around for
6573 now but deprecated. [dirkx]
6575 *) Clean up the base64 and SHA1 additions and make sure they are
6576 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
6577 files. [Roy Fielding]
6579 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
6580 checking. Allow compiling on VS 6.0. [Randy Terbush]
6582 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
6584 *) Use TestCompile to search for the truerand library (rather than blindly
6585 assuming its existence). If it is not found, complain (but do not
6586 exit - yet). [Martin Kraemer]
6588 *) We forgot to add the new exported function names to
6589 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
6591 *) Add description of -T command-line option to usage().
6592 [Ralf S. Engelschall]
6594 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
6595 searched only AFTER libap has been searched, because libap needs
6596 some symbols from libos. [Martin Kraemer]
6598 *) Fix conflict with original mod_digest related to the symbol of the
6599 module dispatch list (which has to be unique for DSO and follow the
6600 usual conventions for the installation procedure).
6601 [Ralf S. Engelschall]
6603 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6604 for other platforms as well. [Martin Kraemer]
6606 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6607 types by AP_LONG and replace reference to renamed variable 'ubuf'
6608 by 'buffer'. [Martin Kraemer]
6610 Changes with Apache 1.3.8 [not released]
6612 *) Flush the output buffer immediately after sending an error or redirect
6613 response, since the result may be needed by the client to abort a
6614 long data transfer or restart a series of pipelined requests.
6615 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
6617 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6618 [Ian Turner <iant sequent.com>] PR#4735
6620 *) Local struct mmap in http_core.c conflicted with system structure
6621 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6623 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6624 [Ronald Tschalär <ronald innovation.ch>]
6626 *) Fix a memory leak where the module counts were getting messed
6627 up across restarts. [David Harris <dharris drh.net>]
6629 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6630 properly in mod_access.
6631 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
6633 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6634 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
6636 *) PORT: Support for compaq/tandem/com.
6637 [Michael Ottati <michael.ottati compaq.com>, dirkx]
6639 *) Added SHA1 password encryption support to easy migration from
6640 Netscape servers. See support/SHA1 for more information.
6641 Caused the separation of ap_md5.c into md5, sha1 and a general
6642 ap_checkpass.c with just a validate_passwd routine. Added a
6643 couple of flags to support/htpasswd. Some reuse of the to64()
6644 function; hence renamed to ap_to64().
6645 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
6647 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6648 with ASCII/EBCDIC conversions in "ident" query.
6649 [David McCreedy <McCreedy us.ibm.com>]
6651 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6652 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6653 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6655 *) Fix SIGSEGV on some systems because the Vary fix below included
6656 a call to table_do with a variable argument list that was not
6657 NULL terminated. Replaced with better implementation. [Roy Fielding]
6659 Changes with Apache 1.3.7 [not released]
6661 *) The "Vary" response header field is now sanitised right before
6662 the header is sent back to the client. Multiple "Vary" fields
6663 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6664 "Vary: host, negotiate, host, accept-language") are reduced to
6665 single instances. This is a better solution than the force-no-vary
6666 one (which is still valid for clients that can't cope with Vary
6667 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6669 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
6671 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6672 least on Linux and FreeBSD for now.
6675 *) Win32: More apache -k restart work. Restarts are now honored
6676 immediately and connections in the listen queue are -not- lost.
6677 This is made possible by the use of the WSADuplicateSocket()
6678 call. The listeners are opened in the parent, duplicated, then
6679 the duplicates are passed to the child. The original listen sockets
6680 are not closed by the parent across a restart, thus the listen queue
6682 [Bill Stoddard <stoddard raleigh.ibm.com>]
6684 *) Fix handling of case when a client has sent "Expect: 100-continue"
6685 and we are going to respond with an error, but get stuck waiting to
6686 discard the body in the pointless hope of preserving the connection.
6687 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
6689 *) Fix 'configure' to work correctly with SysV-based versions of
6690 'tr' (consistent with Configure's use as well). [Jim Jagielski]
6692 *) apxs: Add "-S var=val" option which allows for override of CFG_*
6693 built-in values. Add "-e" option which works like -i but doesn't
6694 install the DSO; useful for editing httpd.conf with apxs. Fix
6695 editing code so that multiple invocations of apxs -a will not
6696 create duplicate LoadModule/AddModule entries; apxs can now be
6697 used to re- enable/disable a module. [Wilfredo Sanchez]
6699 *) Win32: Update the server to use Winsock 2. Specifically, link with
6700 ws2_32.lib rather than wsock32.lib. This gives us access to
6701 WSADuplcateSocket() in addition to some other enhanced comm APIs.
6702 Win 95 users may need to update their TCP/IP stack to pick up
6703 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
6704 [Bill Stoddard <stoddard raleigh.ibm.com>]
6706 *) Win32: Redirect CGI script stderr (script debug info) into the
6707 error.log when CGI scripts fail. This makes Apache on Win32
6708 behave more like Unix.
6709 [Bill Stoddard <stoddard raleigh.ibm.com>]
6711 *) Fixed `httpd' usage display: -D was missing.
6712 [Ralf S. Engelschall] PR#4614
6714 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
6715 [Ralf S. Engelschall] PR#4561, PR#4562
6717 *) OS/2: Fix problem with accept lock semaphores where server would die with
6718 "OS2SEM: Error 105 getting accept lock. Exiting!"
6719 [Brian Havard] PR#4505
6721 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
6722 [Randy Terbush <randy covalent.net>]
6724 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
6725 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
6727 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
6728 command potentially _is_ GCC. [Ralf S. Engelschall]
6730 *) Fix apxs build issues on AIX
6731 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
6733 *) DocumentRoot Checking: Under previous versions, when Apache
6734 first started up, it used to do a stat of each DocumentRoot to
6735 see if it existed and was a directory. If not, then an error
6736 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
6737 does not exist, you will get error messages in error_log. If
6738 the '-t' command line option is used (to check the configuration)
6739 the check of DocumentRoot IS performed. An additional command
6740 line option, '-T', has been added if you want to avoid the
6741 DocumentRoot check even when checking the configuration.
6744 *) Win32: The query switch "apache -S" didn't exit after showing the
6745 vhost settings. That was inconsistent with the other query functions.
6746 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
6748 *) Win32: Changed behaviour of apache -k restart.
6749 Previously, the server would drain all connections in the stack's
6750 listen queue before honoring the restart. On a busy server, this
6751 could take hours. Now, a restart is honored almost immediately.
6752 All connections in Apache's queues are handled but connections in
6753 the stack's listen queue are discarded. Restart triggered by
6754 MaxRequestPerChild is unchanged.
6755 [Bill Stoddard <stoddard raleigh.ibm.com>]
6757 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
6758 the accept loop. Good for a 5% performance boost. Cleaned up
6759 parent/child process management code.
6760 [Bill Stoddard <stoddard raleigh.ibm.com>]
6762 *) Added ceiling on file size for memory mapped files.
6763 [John Giannandrea <jg meer.net>] PR#4122
6765 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
6766 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
6767 [Henri Gomez <gomez slib.fr>, Ralf S. Engelschall]
6769 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
6770 use this at least for Expat. [Ralf S. Engelschall]
6772 *) Allow .module files to specify libraries with Lib:.
6775 *) Allow SetEnvIf[NoCase] to test environment variables as well
6776 as header fields and request attributes. [Ken Coar]
6778 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
6779 content-types are "text/html;parameters". PR#4524 [Ken Coar]
6781 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
6782 never accepted into any standard, and it opens up certain DoS
6783 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
6785 *) TestCompile updated. We can now run programs and output the
6786 results during the Configure process. [ Jim Jagielski]
6788 *) The source is now quad (long long) aware as needed. Specifically,
6789 the Configure process determines the correct size of off_t and
6790 *void. When the OS/platform/compiler supports quads, ap_snprintf()
6791 provides for the 'q' format qualifier (if quads are not available,
6792 'q' is silently "demoted" to long). [Jim Jagielski]
6794 *) When the username or password fed to htpasswd is too long, include the
6795 size limit in the error message. Also report illegal characters
6796 (currently only ':') in the username. Add the size restrictions
6797 to the man page. [Ken Coar]
6799 *) Fixed the configure --without-support option so it doesn't result in
6800 an infinite loop. [Marc Slemko]
6802 *) Piped error logs could cause a segfault if an error occured
6803 during configuration after a restart.
6804 [Aidan Cully <aidan panix.com>] PR#4456
6806 *) If a "Location" field was stored in r->err_headers_out rather
6807 than r->headers_out, redirect processing wouldn't find it and
6808 the server would core dump on ap_escape_html(NULL). Check both
6809 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
6810 if Location isn't set. [Doug MacEachern, Ken Coar]
6812 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
6813 of the Expat 1.0.2 distribution. [Greg Stein]
6815 *) Replace regexec() calls with calls to a new API stub function
6816 ap_regexec(). This solves problems with DSO modules which use the regex
6817 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]
6819 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
6820 environment variables can be set according to the protocol version

6839 HeaderName files in mod_autoindex. Removed the restriction on
6840 "/"s in ReadmeName and HeaderName directives since the *sub_req*
6841 routines will deal with the access issues. (It's now possible to

6878 being newer than Configuration so that it is less likely to fail
6879 when using APACI and shadow sources. [Wilfredo Sanchez]
6881 *) PORT: Add initial support for Mac OS (versions 10.0 and
6882 greater). Use Mac OS X Server layout for now. Clean up dyld code
6883 in unix/os.c, and don't install the dyld error handlers, which
6884 are no longer needed in Mac OS. [Wilfredo Sanchez]
6886 *) Rename Rhapsody layout to "Mac OS X Server". Change install
6887 locations to appropriate ones for user-built (as opposed to
6888 system) installs. [Wilfredo Sanchez]
6890 *) Modify mod_autoindex's handling of AddDescription so that the
6891 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
6893 *) Add functionality to the install-bindist.sh script created by
6894 binbuild.sh to use tar when copying distribution files to the
6895 serverroot. This allows upgrading an existing installation
6896 without nesting the new distribution in the old.
6898 install-bindist.sh now detects the local perl5 path to install
6899 apxs and dbmmanage with proper path to perl interpreter.
6901 Add an install-binsupport target which copies the source files
6902 for apxs and dbmmanage to bindist to allow these scripts to
6903 be properly installed relative to the destination serverroot.

7020 htpasswd utility was limiting passwords to only 8 characters.
7023 *) EBCDIC platforms: David submitted patches for two bugs in the
7024 MD5 digest port for EBCDIC machines:
7025 a) the htdigest utility overwrote the old contents of the digest file
7026 b) the Content-MD5 header value (ContentDigest directive) was wrong
7027 when the returned file was not converted from EBCDIC, but was a
7028 binary (e.g., image file) in the first place.
7029 [David McCreedy <mccreedy us.ibm.com>]

7070 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
7071 a roughly 5 fold speed up. [Brian Havard]
7073 *) proxy ftp: instead of using the hardwired string "text/plain" as
7074 a fallback type for files served by the ftp proxy, use the
7075 ap_default_type() function to determine the configured type.
7076 This allows for special configurations like
7077 <Directory proxy:ftp://some.host>
7078 DefaultType gargle/blurb
7080 Additionally, add the Content-Encoding: header to FTP proxy replies
7081 when the encoding is defined (by the AddEncoding directive).
7082 Because it was missing, it was almost impossible to browse compressed
7083 files using the FTP proxy (works now perfectly in Communicator).
7084 The ftp proxy now also returns the Date: and Server: header lines (if not
7085 much else... This code is "somewhat" broken) like normal requests do.
7088 *) Be more smart in APACI's configure script when determining the UID/GID
7089 for User/Group directives and use the determined UID/GID to initialize
7090 the permissions on the proxycachedir.
7091 [Dirk-Willem van Gulik, Ralf S. Engelschall]
7093 *) Changed the forking-prior-to-cleanup in the proxy module to first

7095 the number of fork()s from one/request to just the odd one an hour.
7096 [Dirk-Willem van Gulik]

7125 *) M_INVALID needed a value within the scope of METHODS so that unknown
7126 methods can be access controlled. [Roy Fielding] PR#3821
7128 *) Added PassAllEnv; makes server's entire environment available
7129 to CGIs and SSIs executed within directive's scope. [Ken Coar]
7131 *) ap_uuencode() always added two trailing '='s and encoding of
7132 8 bit characters on a machine with signed char may produced
7133 incorrect results. Additionally ap_uuencode() should now
7134 work correctly on EBCDIC platforms.
7135 [Ronald Tschalär <ronald innovation.ch>] PR#3411
7137 *) WIN32: Binary installer now runs the configuration DLL before
7138 the reboot prompt (which is only given if MSVCRT.DLL system
7139 DLL is new or updated). This should avoid the configuration
7140 directory being empty after installation. [Paul Sutton]
7141 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

7151 version). [Dean Gaudet] PR#2723, 3531

7164 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
7165 for 8-bit safeness. [Dean Gaudet]
7167 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
7168 because SPARCs have a small machine-specific maximum size for the Global
7169 Offset Table which is often exceeded when compiling one of the larger
7170 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977
7172 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

7199 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
7202 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
7203 to make platform installations easier. [Wilfredo Sanchez]
7205 *) In configure, do not append the target name to the directory path if
7206 the path already contains "apache". [Ralf S. Engelschall]
7208 *) SIGPIPE is now ignored by the server core. The request write routines
7209 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
7210 correctly check for output errors and mark the connection as aborted.
7211 Replaced many direct (unchecked) calls to ap_b* routines with the
7212 analogous ap_r* calls. [Roy Fielding]
7214 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
7215 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
7216 Furthermore map lookups for non-existent keys are now cached as well.
7217 Additionally "txt" maps are now parsed with simple string functions
7218 instead of using ap_pregcomp(). As a side effect a bug that prevented
7219 the usage of keys containing the "," character was fixed.
7220 The changes drastically improve the performance when large rewrite maps
7222 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
7224 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
7225 other than GET, and const'd the definition of method in request_rec.
7228 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
7230 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
7231 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
7233 *) Add %V to mod_log_config, this logs the hostname according to the
7234 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
7235 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
7237 *) Add support for \n and \t to mod_log_config, can be used to produce
7238 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
7240 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
7242 *) Added informative error messages for failed munmap() and fseek() calls

7245 *) Added some informative error messages for some failed malloc()
7246 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
7248 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
7249 is removed. This allows <Directory proxy:*> directives to work and
7250 prevents invalid requests from killing the process.
7251 [Brian Havard <brianh kheldar.apana.org.au>]
7253 *) Reorganised FAQ document.

7262 *) Win32: The filename validity checker now allows filenames containing
7263 characters in the range 0x80 to 0xff (for example accented characters).
7264 [Paul Sutton] PR#3890
7266 *) Added conditional logging based upon environment variables to
7267 mod_log_config. mod_log_referer and mod_log_agent
7268 are now deprecated. [Ken Coar]
7270 *) Allow apache acting as a proxy server to relay the real
7271 reason of a failure to a client rather than the "internal
7272 server error" it does currently. The general exposure mechanism
7273 can be triggered by any module by setting the "verbose-error-to"
7274 note to "*"; this allows more than just proxy errors to be exposed.
7275 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
7277 *) Moved man pages for ab and apachectrl to section 8.

7283 *) Tweak modules Makefile generated by Configure so that it handles
7284 the test case of no modules being selected. [<chaz reliant.com>]
7286 *) Added a <LimitExcept method ...> sectioning directive that allows
7287 the user to assign authentication control to any HTTP method that
7288 is *not* given in the argument list; i.e., the logical negation
7289 of the <Limit> directive. This is particularly useful for controlling
7290 access on methods unknown to the Apache core, but perhaps known by
7291 some module or CGI script. [Roy Fielding, Tony Finch]
7293 *) Prevent apachectl from complaining if the PIDFILE exists but
7294 does not contain a process id, as might occur if the server is
7295 being rapidly restarted. [Wilfredo Sanchez]
7297 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]

7308 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
7310 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
7311 to util.c for parsing an HTTP header field value to extract the next
7312 list item, taking into account the possible presence of nested comments,
7313 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
7314 insignificant whitespace and lowercases non-quoted tokens.
7315 [Roy Fielding] PR#2065
7317 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
7318 code different from 500. This allows the proxy to, e.g., return
7319 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
7321 *) Fix ordering of language variants for the case where the traditional
7322 negotiation algorithm is being used with multiple language variants
7323 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
7325 *) Do not round the TCN quality calculation to 5 decimal places,
7326 unlike RFC 2296, because the calculation might need 12 decimal places
7327 to get the right result. [Roy Fielding]
7329 *) Remove unused code to disable transparent negotiation when
7330 negotiating on encoding only, as we now handle encoding too
7331 (though this is nonstandard for TCN), remove charset=ISO-8859-1
7332 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
7333 some debugging statements within mod_negotiation. [Koen Holtman]
7335 *) Fixed a rare memory corruption possibility in mod_dir if the index
7336 file is negotiable and no acceptable variant can be found.
7337 [Dean Gaudet, Roy Fielding, Martin Kraemer]
7339 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
7340 searching the Win32 registry for script interpreters.
7343 *) Win32: The compiled-in default filename for the error log is now
7344 error.log, which matches the default in the distributed httpd.conf.
7347 *) Win32: Any error messages from -i or -u command line options are now
7348 displayed on the console output rather than sent to the error log.
7349 Also the "Running Apache..." message is not output unless Apache is
7350 going to serve requests. [Paul Sutton]
7352 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
7353 and use a private significator ('$apr1$') to mark passwords as
7354 being smashed with our own algorithm. Also abstract the password
7355 checking into a new ap_validate_password() routine. [Ken Coar]
7357 *) Win32: The filename validity checker now allows "COM" but refuses
7358 access to "COM1" through "COM4". This allows filenames such
7359 as "com.name" to be served. [Paul Sutton] PR#3769.
7361 *) BS2000: Adapt to the new ufork() system call interface which will
7362 make subtasking easier on the OSD/POSIX mainframe environment.
7365 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
7366 ap_compat.h. [David White <david persimmon.com>] PR#3725
7368 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
7369 use `.db' instead of `.pag' not only for FreeBSD, but also when
7370 the NDBM library looks like Berkeley-DB based.
7371 [Ralf S. Engelschall] PR#3773
7373 *) Add ability to handle DES or MD5 authentication passwords.
7374 [Ryan Bloom <rbb Raleigh.IBM.Com>]
7376 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
7378 *) SECURITY: Avoid some buffer overflow problems when escaping
7379 quoted strings. (This overflow was on the heap and we believe
7380 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
7382 *) Let src/Configure be aware of CFLAGS options starting with plus
7383 signs as it's the case for the HP/UX compiler.
7384 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
7386 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
7387 and check to see if the tar we wind up with supports '-h'.
7388 [Jim Jagielski] PR#3671
7390 *) A consistent and conservative style for all shell scripts has been
7391 implemented. Basically, all shell string tests use the traditional
7392 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
7393 to protect against bare null variable strings (ie: wrapping both
7394 sides with double quotes and prepending 'x'). 'x' was chosen
7395 because it's more universal and hopefully easier for old shell
7396 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
7399 *) The status module now prints out both the main server generation as
7400 well as the generation of each process. Also, the vhost info is
7401 printed with '?notable'. [Jim Jagielski]
7403 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
7404 and this makes its functions available to things in src/support.
7407 Changes with Apache 1.3.4
7409 *) Renamed macros status_drops_connection to ap_status_drops_connection
7410 and vestigial scan_script_header to ap_scan_script_header_err,
7411 mostly for aesthetic reasons. [Roy Fielding]
7413 *) The query switch "httpd -S" didn't exit after showing the
7414 vhost settings. That was inconsistent with the other query functions.
7417 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
7418 filename to the end of the STANDARD_MODULE_STUFF. Its
7419 presence at the beginning prevented reporting of the filename
7420 for modules compiled before 1 January 1999. [Ken Coar]
7422 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
7423 to detect and prevent access to special DOS device file names.
7424 [Paul Sutton, Ken Parzygnat]
7426 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
7427 and Makefile_win32_debug.txt (debug build) that work on Win95.
7428 Run each of the following from the src directory:
7429 nmake /f Makefile_win32.txt # compiles normal build
7430 nmake /f Makefile_win32.txt install # compiles and installs
7431 nmake /f Makefile_win32.txt clean # removes compiled junk
7432 nmake /f Makefile_win32_debug.txt # compiles debug build
7433 nmake /f Makefile_win32_debug.txt install
7434 nmake /f Makefile_win32_debug.txt clean
7437 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
7438 to build binary distributions. [Lars Eilebrecht]
7440 *) IndexOptions SuppressColumnSorting only turned off making
7441 the column headers anchors; you could still change the display
7442 order by manually adding a '?N=A' or similar query string to the
7443 URL. Now SuppressColumnSorting locks in the sort order so
7444 it can't be overridden this way. [Ken Coar]
7446 *) Added IndexOrderDefault directive to supply a default sort order
7447 for FancyIndexed directory listings. [Ken Coar] PR#1699
7449 *) Change the ap_assert macro to a variant that works on all platforms.
7450 [Richard Prinz <richard.prinz cso.net>] PR#2575
7452 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
7453 search for an underscore on dlsym() (as it's already the case
7454 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
7456 *) Small fix for mod_env.html: The module was documented as to be _not_
7457 compiled into Apache per default, although it _IS_ compiled into
7458 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
7460 *) Instead of fixing a bug in the generation procedure for config.status (a
7461 backslash was missing) we remove the bug together with it's complete
7462 context because the special cases of the past can now no longer occur
7463 because of the recent magic for the --with-layout default.
7464 [Ralf S. Engelschall] PR#3590
7466 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
7467 making sure the src/support/ tools are _forced_ to be build last (they
7468 depend on other libraries).
7469 [Markus Theissinger <markus.theissinger gmx.de>]
7471 *) Fix installation procedure: Now that os-inline.c is actually used (a
7472 recently fixed bug prevented this) we need to also install os-include.c
7473 in addition to os.h into the PREFIX/include/ location or building of
7474 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
7476 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
7477 allow us to distinguish between a garbled DSO (or even a file which isn't
7478 an Apache module DSO at all) and a DSO which doesn't match the current
7479 Apache API. [Ralf S. Engelschall] PR#3152
7481 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
7482 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
7483 match case insensitive (this especially avoids nasty patterns like
7484 `[tT][eE][sS][tT]'). Second two additional internal map functions
7485 `escape' and `unescape' were added which can be used to escape/unescape
7486 to/from hex-encodings in URLs parts (this is especially useful in
7487 combination with map lookups).
7488 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
7490 *) Renamed the macro escape_uri() to ap_escape_uri() which was
7491 forgotten (because it was a macro) in the symbol renaming process.
7492 [Ralf S. Engelschall]
7494 *) Fix some inconsistencies related to the scopes of directives. The only
7495 user visible change is that the directives `UseCanonicalName' and
7496 `ContentDigest' now use the (more correct) `Options' scope instead of
7497 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
7499 *) Using DSO, the Server token was being mangled. Specifically, the
7500 module's token was being added first before the Apache token. This
7501 has been fixed. [Jim Jagielski]
7503 *) Major overhaul of mod_negotiation.c, part 2.
7504 - properly handle "identity" within Accept-Encoding.
7505 - allow encoded variants in RVSA negotiation and let them appear in
7506 the Alternates field using the non-standard "encoding" tag-list.
7507 - fixed both negotiation algorithms so that an explicitly accepted
7508 encoding is preferred over no encoding if "identity" is not
7509 included within Accept-Encoding.
7510 - added ap_array_pstrcat() to alloc.c for efficient concatenation
7511 of large substring sequences.
7512 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
7515 *) Major overhaul of mod_negotiation.c, part 1.
7516 - cleanups to mod_negotiation comments and code structure
7517 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
7518 support for everything in the upcoming HTTP/1.1
7519 revision (draft-ietf-http-v11-spec-rev-06.txt).
7520 - language tag matching also handles tags with more than 2
7522 - empty Accept, Accept-Language, Accept-Charset headers are
7523 processed correctly; previously an empty header would make all
7524 values acceptable instead of unacceptable.
7525 - allowed for q values in Accept-Encoding
7526 - added support for transparent content negotiation (rfc2295 and
7527 rfc2296) (though we do not implement all features in these drafts,
7528 e.g. no feature negotiation). Removed old experimental version.
7529 - implemented 'structured entity tags' for better cache correctness
7530 (structured entity tags ensure that caches which can deal with Vary
7531 will (eventually) be updated if the set of variants on the server
7533 - this involved adding a vlist_validator element to request_rec
7534 - this involved adding the ap_make_etag() function to the global API
7535 - modified guessing of charsets used by Apache negotiation algorithm
7536 to guess 'no charset' if the variant is not a text/* type
7537 - added code to sort multiviews variants into a canonical order so that
7538 negotiation results are consistent across backup/restores and mirrors
7539 - removed possibility of a type map file resolving to another type map
7540 file as its best variant
7541 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
7543 *) RFC2396 allows the syntax http://host:/path (with no port number)
7544 but the proxy disallowed it (ap_proxy_canon_netloc()).
7545 [David Kristol <dmk bell-labs.com>] PR#3530
7547 *) When modules update/modify the file name in the configfile_t structure,
7548 syntax errors will report the updated name, not the original one.
7549 [Fabien Coelho <coelho cri.ensmp.fr>] PR#3573
7551 *) Correct some filename case assumptions from WIN32 to
7552 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
7554 *) For %v log ServerName regardless of the UseCanonicalName
7555 setting (similarly for %p). [Dean Gaudet]
7557 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
7558 rather late (too late for some invocations of TestCompile).
7559 This improves the make environment available to TestCompile and
7560 the *.module scripts. [Martin Kraemer]
7562 *) The hashbang emulation code in ap_execve.c would interpret
7563 #!/hashbang/scripts correctly, but failed to fall back to a
7564 standard shell for scripts which did NOT start with #!
7565 Now SHELL_PATH is started in these cases. [Martin Kraemer]
7567 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
7570 *) Update APXS manual page: some -q option arguments were missing
7571 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
7573 *) Cleanup the command line options: `-?' was documented to show
7574 the usage list but does it with an error because `?' is not a valid
7575 command. OTOH a lot of users expect `-h' to print such a usage list and
7576 instead are annoyed for ages by our huge unreadable list of directives.
7577 So we now changed the command line options this way:
7579 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
7580 very similar to the popular linker option.
7582 Intent: while -l gives the small list of modules, -L now gives the
7583 large list of directives implemented by these modules. This is also
7584 consistent with -v (short version info) and -V (large version info).
7586 Intent: it's now the expected option ;-)
7587 The manual page was adjusted accordingly.
7588 [Ralf S. Engelschall] PR#2714
7590 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
7591 wasn't defined. [Rick Franchuk <rickf transpect.net>]
7593 *) Removed recently introduced bugs and disfigurements in APACI:
7594 o fixed argument line processing: using $args was broken: It was not
7595 initialized and using args="$args $apc_option" and even args="$args
7596 \"$apc_option\"" fails in the second processing round for any arguments
7597 containing whitespaces. The only correct way is to use the construct
7598 "$@" (but not possible here) or iterate _both_ times over the implicit
7599 argument line (no argument to for-loop) which is what we now use.
7600 o make --with-layout=Apache the default without creating
7601 redundancy (copying the --with-layout block in the argument parsing
7602 loop). We achieve this by using the "$@" construct together with the
7603 `set' command to prepend --with-layout=Apache to the command line in
7604 case --with-layout is not used.
7605 o fixed auto-suffix handling now that config.layout exists.
7606 Paths which are auto-suffixed are marked with a trailing plus sign in
7607 config.layout and every path now can be marked this way (not only the
7608 four paths for which we do it currently). Additionally the suffix is
7609 no longer a static one. Instead it's now `/<target>' where <target> is
7610 the argument of the --target option or per default `httpd'.
7611 o allow also tabs (and only spaces) where we match whitespaces
7612 o various fixes and cleanups related to used shell coding style
7613 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7614 o trimmed output of --help to fit into 80 columns
7615 [Ralf S. Engelschall]
7617 *) Added two new core API functions, ap_single_module_configure() and
7618 ap_single_module_init(), which are now used by mod_so to configure a module
7619 after loading. [Ralf S. Engelschall]
7621 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
7622 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
7623 of ap_config.h to allow serialized accept for multiport listens.
7624 [Roy Fielding, Curt Sampson] PR#3120
7626 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
7627 of ap_config.h that would skip several defines if DEFAULT_GROUP
7628 was overridden. [Roy Fielding]
7630 *) PORT: The I86 version of DGUX has support for strncasecmp and
7631 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
7633 *) Fix ordering of definitions in ap_config.h so that ap_inline is
7634 defined before it might be used. [Victor Khimenko]
7636 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
7637 [Tom Serkowski <tks bsdi.com>] PR#3453
7639 *) Make generation of src/Configuration.apaci more robust: It failed to
7640 differenciate between modules when one module name was a postfix of
7641 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
7642 just XXX (think about totally non-standard names like "apache_ssl", too).
7643 [Ralf S. Engelschall] PR#3380
7645 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
7646 since 1.3b7) and make whitespace handling more robust (it failed horrible
7647 when whitespaces were present in the arguments of -D options).
7648 [Ralf S. Engelschall] PR#3240
7650 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
7651 creates an external package shadow tree in DIR before the local build
7652 shadow tree is generated under DIR. This way one can have the extracted
7653 Apache distribution tree read-only on NFS or CDROM and still build Apache
7654 from these sources. An automatically triggered VPATH-like mechanism is
7655 provided through the TOP variable, too.
7656 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez apple.com>]
7658 *) Fix negotiation so that a Vary response header is correctly
7659 generated when, for a particular dimension, variants only vary
7660 in having or not having a value for that dimension. [Paul Sutton]
7662 *) Fix negotiation so that we prefer an encoded variant over an
7663 unencoded variant if the user-agent explicitly says it can
7664 accept that encoding. Previously we always preferred the unencoded
7666 [Paul Ausbeck <paula alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
7668 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
7669 and the usage page was inconsistent with the functionality and manpage.
7670 [Ralf S. Engelschall]
7672 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
7673 They can occur multiple times and their arguments (`xxx') are passed AS
7674 IS to the compiler/linker command. [Ralf S. Engelschall]
7676 *) Fixed possible (but harmless in practice) bug in the DBM lookup
7677 procedure of mod_rewrite: very long keys were truncated.
7678 [Ralf S. Engelschall]
7680 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
7681 identifier, currently "Apache" and "GNU" are pre-defined in the file
7682 config.layout. Custom layouts are possible by using FILE:ID as the
7683 argument where the layout ID is taken from FILE.
7685 The config.layout file consists of <Layout ID>..</Layout> sections
7686 where inside those sections "path_variable: path_value" pairs can be
7687 specified. These lines are converted to path_variable='path_value'.
7689 *) Add a DefaultLanguage directive so that files missing a language
7690 extension (e.g., .fr, .de) can be labelled as being some other
7691 default language. DefaultLanguage can appear in <Directory> and
7692 <Files> containers as well as .htaccess files. [Paul Sutton]
7695 *) Fix TARGET configuration when configuring and installing using
7696 APACI configure. TARGET now defines the basename of the configuration
7697 file, startup script, manual page, etc. log_error_core() now reports
7698 the server binary name given by argv[0]. TARGET can now also be defined
7699 with --target=TARGET parameter passed to APACI configure.
7700 [Ralf Engelschall, Randy Terbush]
7702 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
7703 rather than OPT_INCLUDES [Rainer Schoepf <schoepf uni-mainz.de>]

7725 *) Fallback to native compilers for IRIX-32 platform. It seems that
7726 a gcc 2.8.1 compiled apache is logging client addresses with all
7727 bits set (255.255.255.255). This is the second such problem caused
7728 by gcc 2.8.1 compiler. The first being broken semaphore locking.

7786 response of 403 (Forbidden). [Roy Fielding]
7788 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
7789 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
7791 *) Fix in mod_autoindex: for files where the last modified time stamp was
7792 unavailable, an empty string was printed which was 2 bytes short.
7793 The size and description columns were therefore not aligned correctly.
7794 [Martin Kraemer] (no PR#)
7796 *) Update BS2000 OS code to work with recent versions. Starting with
7797 release A17, the child fork() must be replaced by a _rfork().
7798 (BS2000 only) [Martin Kraemer]
7800 *) Add the actual server_rec structure of the specific Vhost to the
7801 scoreboard file and avoid a string copy (as well as allow some
7802 further future enhancements). [Harrie Hazewinkel
7803 <harrie.hazewinkel jrc.it>]
7805 *) Add APACI --permute-module=foo:bar option which can be used to
7806 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
7807 in the Configuration[.apaci] file. Two special and important variants are
7808 supported for the option argument: first BEGIN:foo which permutes module
7809 mod_foo with the begin of the module list, i.e. it `moves' the module to
7810 the begin of the list (gives it lowest priority). And second foo:END
7811 which permutes mod_foo with the end of the module list, i.e. it `moves'
7812 the module to the end of the list (gives it highest priority).
7813 [Ralf S. Engelschall]
7815 *) Fix problem with 'apache -k shutdown' and startup event
7816 synchronisation (Win32). [Ken Parzygnat <kparz raleigh.ibm.com>]
7819 *) The config parser wasn't correctly noticing a missing '>'
7820 on container start lines (e.g., it wouldn't spot
7821 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom us.ibm.com>]
7824 *) Add a 'RemoveHandler' directive which will selectively remove
7825 all handler associations for the specified file extensions.
7826 [Ryan Bloom <rbbloom us.ibm.com>] PR#1799.
7828 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
7829 ResourceConfig directives on Win32. Also add a note to the effect
7830 of 'useless User directive ignored on Win32' to the errorlog if
7831 a User directive is encountered on Win32.
7832 [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2078, 2303.
7834 *) Fix multiple whitespace handling in imagemaps for mod_imap which was
7835 broken since Apache 1.3.1 where we took out compressing of multiple
7836 spaces in ap_cfg_getline().
7837 [Ivan Richwalski <ivan seppuku.net>] PR#3249
7839 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
7840 initialized correctly and the db_open() call used an invalid mode
7841 parameter. [Ron Klatchko <ron ckm.ucsf.edu>] PR#3171
7843 *) PORT: DSO support for UnixWare 7
7844 [Ralf S. Engelschall, Ron Record <rr sco.com>]
7846 *) Merge the contents of the {srm,access}.conf-dist* files into the
7847 httpd.conf-dist* files. The srm and access files now contain
7848 only comments, and httpd.conf has all the combined contents in
7849 a rational order. [Ken Coar]
7851 *) PORT: DSO/ELF support for FreeBSD 3.0.
7852 [Ralf S. Engelschall, Dirk Froemberg <ibex physik.TU-Berlin.DE>]
7854 *) Add a "default-handler" handler that calls the default_hander()
7855 function which is normally called for static content. This allows
7856 you to override a specific handler. [Marc Slemko]
7858 *) Further simplify checking for absolute paths by replacing an
7859 hard-coded syntax check with a call to a routine we already created to
7860 do this. [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2976, 3074
7862 *) Log an error if we encounter a malformed "require" directive
7863 in mod_auth if we know that we know that no other module can
7864 deal with it. [Marc Slemko]
7866 *) Remove ap_private_extern method of hiding conflicting symbols
7867 on the NEXT platform because it is not correct for all versions,
7868 and the versions for which it is correct are unknown.
7869 [Wilfredo Sanchez <wsanchez apple.com>]
7871 *) Fix inheritance of IndexOptions NameWidth and remove unintended
7872 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
7874 *) Fix per-directory config merging for cases in which a 500 error
7875 is encountered in an .htaccess file somewhere down the tree.
7878 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
7880 *) Fixed a segmentation violation in mod_proxy when a response is
7881 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
7883 Changes with Apache 1.3.3
7885 *) Added a complete implementation of the Expect header field as
7886 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
7887 response when we already know the final status, which is mighty
7888 useful for PUT responses that result in 302 or 401. [Roy Fielding]
7890 *) Remove extra trailing whitespace from the getline results as part
7891 of the protocol processing, which is extra nice because it works
7892 between continuation lines, is almost no cost in the normal case
7893 of no extra whitespace, and saves memory. [Roy Fielding]
7895 *) Added new HTTP status codes and default response bodies from the
7896 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
7897 HTTP Extension Framework (510) specifications. Did not add the
7898 WebDAV 424 and 425 codes because they are bogus. We don't use any
7899 of these codes yet, but they are now available to 3rd-party modules.
7902 *) Fix a possible race condition between timed-out requests and the
7903 ap_bhalfduplex select that might result in an infinite loop on
7904 platforms that do not validate the descriptor. [Roy Fielding]
7906 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
7907 running Apache server [Paul Sutton]
7909 *) Fix mod_autoindex bug where directories got a size of "0k" instead
7910 of "-". [Martin Plechsmid <plechsmi karlin.mff.cuni.cz>, Marc Slemko]
7913 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker jetair.be>]
7915 *) Add the server signature text (from the core ServerSignature directive)
7916 to the list of envariables available to scripts, SSI, and the like.
7919 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
7920 [M. Laak <maert proinv.ee>] PR#3108
7922 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
7923 calculation in mod_status for all systems which don't have POSIX
7924 sysconf() (like UTS 2.1) and not only for the NEXT platform.
7925 [Dave Dykstra <dwd bell-labs.com>] PR#3055
7927 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
7928 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
7929 instead of ap_getword(..., ' ') (which parses only according to spaces
7930 but not tabs). [James Morris <jmorris intercode.com.au>,
7931 Ralf S. Engelschall] PR#3105
7933 *) Fix the SERVER_NAME variable under sub-request situations (where
7934 `UseCanonicalName off' is used) like CGI's called from SSI pages or
7935 RewriteCond variables by adopting r->hostname to sub-requests.
7936 [James Grinter <jrg blodwen.demon.co.uk>] PR#3111
7938 *) Fix stderr redirection under syslog-based error logging situation.
7939 [Youichirou Koga <y-koga jp.FreeBSD.org>] PR#3095
7941 *) Document `ErrorLog syslog:facility' variant of error logging.
7942 [Youichirou Koga <y-koga jp.FreeBSD.org>] PR#3096
7944 *) Fix http://localhost/ hints in top-level INSTALL document.
7945 [Rob Jenson <robjen spotch.com>, Ralf S. Engelschall] PR#3088
7947 *) Quote paths in default configuration files. [Wilfredo Sanchez]
7949 *) PORT: Remove extra HAVE_SYS_RESOURCE_H define for RHAPSODY since
7950 it is now taken care of properly by the header file tests.
7951 [Wilfredo Sanchez <wsanchez apple.com>]
7953 *) Fix problem with scripts and filehandle inheritance on Win32.
7954 [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2884, 2910
7956 *) Win32 name canonicalisation could end up using the server's
7957 working directory to fill in some blanks. [Ken Parzygnat
7958 <kparz raleigh.ibm.com>] PR#3001
7960 *) Correct invalid assumption by ap_sub_req_lookup_file() that all
7961 absolute paths begin with "/" -- because they don't on Win32.
7962 [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2976, 3074
7964 *) Add [REDIRECT_]VARIANTS environment variable to mod_speling
7965 so that ErrorDocument 300 processors can reformat the list
7966 if desired. [Ken Coar] PR#2859
7968 *) Add +/- incremental prefixes to IndexOptions keywords, and
7969 enable merging of multiple IndexOptions directives. [Ken Coar]
7971 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
7972 <steve.cameron compaq.com>]
7974 *) Reconstructed the loop through multiple htaccess file names so
7975 that missing files are not confused with unreadable files.
7978 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
7979 errno on an error, which leads to one error being mistaken for
7980 another when reading non-existent .htaccess files.
7983 *) OS/2: The new header tests get things right, need to update
7984 ap_config.h. [Brian Havard]
7986 *) The Perl %ENV hash will now be setup by default when using the
7987 mod_include `perl' command [Doug MacEachern]
7989 *) PORT: Add Pyramid DC/OSx support to configuration mechanism.
7990 [Earle Ake <akee wpdiss1.wpafb.af.mil>]
7992 *) PORT: Fix sys/resource.h handling for Amdahl's UTS 2.1
7993 [Dave Dykstra <dwd bell-labs.com>] PR#3054
7995 *) Correct comment in mod_log_config.c about its internals.
7996 [Elf Sternberg <elf halcyon.com>]
7998 *) Avoid possible line overflow in Configure: Use an awkfile to
7999 handle the creation of modules.c [Jim Jagielski]
8001 Changes with Apache 1.3.2
8003 *) Fix bug in ap_remove_module(), which caused problems for dso's
8004 who were the top_module. [Doug MacEachern]
8006 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
8007 mod_auth_db to both be friendly to users who wants to use this version
8008 and to avoid problems under platforms where only version 2.x is present.
8009 [Dan Jacobowitz <drow false.org>, Ralf S. Engelschall]
8011 *) When using ap_log_rerror(), make the error message available to the
8012 *ERROR_NOTES envariables by default. [Ken Coar]
8014 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
8015 You now must define a BS2000Account name for the server User.
8016 This has fewer security implications than the old approach.
8019 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
8020 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
8021 platform to make the braindead HPUX linker happy. Notice, for the module
8022 DSOs we don't have to use this, because these are loaded manually (and
8023 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
8025 *) Remove 64 thread limit on Win32.
8026 [Bill Stoddard <stoddard raleigh.ibm.com>]
8028 *) Remove redundant substitutions in top-level Makefile.tmpl.
8029 [Ralf S. Engelschall]
8031 *) Fix APACI's `Group' configuration adjustment - especially for Linux
8032 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
8034 *) Make PrintPath work generically instead of having one version
8035 strictly for OS/2. [Jim Jagielski, Brian Havard]
8037 *) Fix the recently introduced C header file checking: We now use the C
8038 pre-processor pass only (and no longer the complete compiler pass) to
8039 determine whether a C header file exists or not. Because only this way
8040 we're safe against inter-header dependencies (which caused horrible
8041 portability problems). The only drawback is that we now have a CPP
8042 configuration variable which has to be determined first (we do a similar
8043 approach as GNU Autoconf does here). When all fails the user still has
8044 the possibility to override it manually via APACI or src/Configuration.
8045 As a fallback for the header check itself we can directly check the
8046 existance of the file under /usr/include, too.
8047 [Ralf S. Engelschall] PR#2777
8049 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
8050 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
8051 ap_private_extern defined to hide symbols that conflict with loaded
8052 dynamic libraries on the NEXT and RHAPSODY platforms.
8053 [Wilfredo Sanchez <wsanchez apple.com>]
8055 *) Delete PID file on clean shutdowns.

8065 [Youichirou Koga <y-koga jp.FreeBSD.org>] PR#2992
8067 *) Fix possible buffer overflow situation in suexec.c.
8068 [Jeff Stewart <jws purdue.edu>] PR#2790
8070 *) Add some more LIBS for the SCO5 platform which are needed for the already
8071 used -lprot. It's actually a bug in SCO5, of course.
8072 [Ronald Record <rr sco.com>] PR#2533
8074 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
8075 trailing slash problem. [Jon Drukman <jsd gamespot.com>] PR#2933
8077 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
8078 platform, because it's only supported under version 4.0 and higher. But
8079 because our GuessOS is still unaware of Digital UNIX versions and the
8080 -msym is just to optimize the DSO statup time a little bit it's safe and
8081 best when we leave it out now. [Ralf S. Engelschall] PR#2969
8083 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
8084 functions: First all three functions no longer fail on strings containing
8085 "%" chars and second ap_log_printf() no longer does a double-formatting
8086 (instead it directly passes through the message to be formatted to the
8087 real internal formatting function). [Ralf S. Engelschall] PR#2941
8089 *) Allow "Include" directives anywhere in the server config
8090 files (but not .htaccess files). [Ken Coar] PR#2727
8092 *) The proxy was refusing to serve CONNECT requests except to
8093 port 443 (https://) and 563 (snews://). The new AllowCONNECT
8094 directive allows the configuration of the ports to which a
8095 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
8097 *) mod_expires will now act on content that is not sent from a file
8098 on disk. Previously it would never add an Expires: header to
8099 any response that did not come from a file on disk; the only
8100 case where it still doesn't (and can't) add one for that type of
8101 content is if you are using a modification date based setting.
8102 [Marc Slemko, Paul Phillips <paulp go2net.com>]
8104 *) Problems encountered during .htaccess parsing or CGI execution
8105 that lead to a "500 Server Error" condition now provide explanatory
8106 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
8109 *) Add NameWidth keyword to IndexOptions directive so that the
8110 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
8113 *) Recognize lowercase _and_ uppercase `uname' results under
8114 SCO OpenServer. [David Coelho <drc ppt.com>]
8116 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
8117 a common problem of (mis-administrated?) IIS servers, make the apache
8118 proxy immune to these errors (and ignore the duplicates, but log
8119 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
8121 *) The <IfModule and <IfDefine block starting directives now only
8122 allow exactly one argument. Previously, the optional negation
8123 character '!' could be separated by whitespace without a syntax
8124 error being reported, albeit defeating the IfModule functionality
8125 (enclosed directives would ALWAYS be executed). By using the
8126 stricter syntax, these hard-to-track errors can be avoided.
8129 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
8130 cause the standalone FancyIndexing directive to logically OR
8131 into any existing IndexOptions settings rather than wiping
8132 them out. [Ken Coar]
8134 *) Changes in ftp proxy: make URL parsing simpler by using the
8136 + Add display of the "current directory" in cases where it's
8137 different from the supplied path (e.g., ftp://user@host/ lives
8138 in /home/user, not in /, therefore clicking on "../" in the
8139 starting directory might send us to /home/).
8140 + When ftp login fails, (esp. when a user name was part of the
8141 URL already), we now return [401 Unauthorized ] to allow the
8142 browser to pop up an authorization dialog. This makes passwords
8143 slightly less visible (they don't appear in the regular log files)
8144 and implements a functionality that other www proxy servers
8148 *) Triggered by the recent "Via:" header changes, the proxy module would
8149 dump core for replies with invalid headers (e.g., duplicate
8150 "HTTP/1.0 200 OK" lines). These errors are now logged and the
8151 core dump is avoided. Also, broken replies are not cached.
8152 [Martin Kraemer] PR#2914
8154 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
8155 plop gmon.out profile data for each child [Doug MacEachern]
8157 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
8158 config.status script to be immune against arguments with whitespaces.
8159 [Yves Arrouye <yves apple.com>] PR#2866
8161 *) Replace the inlined information grabbing stuff for the configuration
8162 adjustment feature (no --without-confadjust) with calls to a new helper
8163 script `buildinfo.sh' which is both more flexible and already proofed to
8164 be more robust against platform differences. This mainly fixes the
8165 recently occured ``sed: command garbled: ...'' problems.
8166 [Ralf S. Engelschall] PR#2776, PR#2848
8168 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
8169 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
8170 without complains after we recently added the POST feature.
8171 [Ralf S. Engelschall]
8173 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
8174 modules as API functions and we forgot them at the big symbol renaming.
8175 [Ralf S. Engelschall]
8177 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
8178 [Youichirou Koga <y-koga jp.FreeBSD.ORG>] PR#2895
8180 *) Dynamically size the filename column of mod_autoindex output.
8183 *) Add the ability to do POST requests to the ab benchmarking tool.
8184 [Kurt Sussman <kls best.com>] PR#2871
8186 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
8187 5 to 10 because there are some users out there who always have 5 to 8
8188 variables in one RewriteRule and had to patch mod_rewrite.h for every
8189 release. So 15 should be now more than enough, even for them. (I never
8190 needed more than 4 in my RewriteRules ;-)
8191 [Ralf S. Engelschall]
8193 *) Make the proxy generate and understand Via: headers
8196 *) Change the proxy to use tables instead of array_headers for
8197 the header lines. [Martin Kraemer]
8199 *) Make sure the config.status file is not overridden when just
8200 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
8202 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
8203 provide a way to trace API changes that add functionality but do
8204 not create a compatibility issue for precompiled modules, etc.
8205 See include/ap_mmn.h for more details. [Randy Terbush]
8207 *) Fix suexec installation under `make install root=xxx' situation.
8208 [Ralf S. Engelschall]
8210 *) Extend the output of the -V switch to include the paths of all
8211 compiled-in configuration files, if they were overridden at
8212 compile time, for least astonishment of the user.
8215 *) When READing a request in ExtendedStatus mode, the "old"
8216 vhost, request and client information is not displayed.
8219 *) STATUS is no longer available. Full status information now
8220 run-time configurable using the ExtendedStatus directive.
8223 *) SECURITY [CAN-1999-1199] (cve.mitre.org):
8224 Eliminate O(n^2) space DoS attacks (and other O(n^2)
8225 cpu time attacks) in header parsing. Add ap_overlap_tables(),
8226 a function which can be used to perform bulk update operations
8227 on tables in a more efficient manner.
8230 *) SECURITY: Added compile-time and configurable limits for
8231 various aspects of reading a client request to avoid some simple
8232 denial of service attacks, including limits on maximum request-line
8233 size (LimitRequestLine), number of header fields (LimitRequestFields),
8234 and size of any one header field (LimitRequestFieldsize). Also added
8235 a configurable directive LimitRequestBody for limiting the size of the
8236 request message body. [Roy Fielding]
8238 *) Make status module aware of DNS and logging states, even if
8239 STATUS not defined. [Jim Jagielski]
8241 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
8243 *) Enhance mod_speling so that CheckSpelling can be used in
8244 <Directory> containers and .htaccess files. [Ken Coar]
8246 *) API: new ap_custom_response() function for hooking into the
8247 ErrorDocument mechanism at runtime [Doug MacEachern]
8249 *) API: new ap_uuencode() function [Doug MacEachern]
8251 *) API: scan_script_header_err_core() now "public" and renamed
8252 ap_scan_script_header_err_core() [Doug MacEachern]
8254 *) The 'status' module will now show the process pid's and their
8255 state even without full STATUS accounting. [Jim Jagielski]
8257 *) Restore the client IP address to the error log messages, this
8258 was lost during the transition from 1.2 to 1.3. Add a new
8259 function ap_log_rerror() which takes a request_rec * and
8260 formats it appropriately. [Dean Gaudet] PR#2661
8262 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
8263 whitespace in input lines -- including within quoted strings.
8265 but leading and trailing whitespace should continue to be
8266 stripped [Martin Kraemer]
8268 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
8269 the ugly use of an env. variable and use command-line args for
8270 alternate $PATH. Make more like advanced 'type's as well.
8273 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
8274 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
8275 <alain.st-denis ec.gc.ca>] PR#2736
8277 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
8279 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
8280 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
8281 directory was renamed to src/os/os2/ for consistency.
8282 [Brian Havard, Ralf S. Engelschall]
8284 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
8285 files (here modules) against other DSO files (here shared libraries).
8286 This is done by determining a subset of LIBS which can be safely used for
8287 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
8288 disabled for all platforms to avoid problems with this (experimental)

8602 than strcmp() to check for parent directory-ness of an entry. Oh, and
8603 make sure the parent directory (if displayed) is *always* listed first
8604 regardless of the sort key. Overall performance winnage should be good
8605 in CPU time, instruction cache, and memory usage, particularly for large
8606 directories. [Ken Coar]

8615 *) Add httpd -t (test) option for running configuration syntax tests only.
8616 If something is broken it complains and exits with a return code
8617 non-equal to 0. This can be used manually by the user to check the Apache
8618 configuration after editing and is also automatically used by apachectl
8619 on (graceful) restart command to make sure Apache doesn't die on restarts
8620 because of a configuration which is now broken since the last (re)start.
8621 This way `apachectl restart' can be used inside cronjobs without having
8622 to expect Apache to be falling down. Additionally the httpd -t can be run

8787 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
8790 *) Transform the configure message "You need root privileges for suEXEC"
8791 from a fatal error into a (more friendly) warning because the building
8792 ("make") of Apache we can allow, of course. Root privileges are needed
8793 only for the installation step ("make install"). So make sure the
8794 user is aware of this fact but let him proceed as long as he can.
8795 [Ralf S. Engelschall] PR#2288
8797 *) Renamed three more functions to common ap_ prefix which we missed at the
8798 Big Symbol Renaming because they're #defines and not real C functions:
8799 is_default_port(), default_port(), http_method().
8800 [Ralf S. Engelschall]
8802 *) A zero-length name after a $ in an SSI document should cause
8803 just the $ to be in the expansion. This was broken during the
8804 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
8806 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
8807 memory. [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2252
8809 *) Fix src/support/httpd.exp (DSO export file which is currently only
8810 used under AIX) because of recent changes to function names.
8811 [Ralf S. Engelschall]
8813 Changes with Apache 1.3b7
8815 *) Make sure a MIME-type can be forced via a RewriteRule even when no
8816 substitution takes place, for instance via the following rule:
8817 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
8818 requested by users in the past to force a single script without a .cgi
8819 extension and outside any cgi-bin dirs to be executed as a CGI program.
8820 [Ralf S. Engelschall] PR#2254
8822 *) A fix for protocol issues surrounding 400, 408, and
8823 414 responses. [Ed Korthof]
8825 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
8827 *) Fix discrepancy in proxy_ftp.c which was causing failures when
8828 trying to connect to certain ftpd's, such as anonftpd.
8829 [Rick Ohnemus <rick ecompcon.com>]
8831 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
8832 logfile instead of fiddling around itself with child spawning stuff.
8833 [Ralf S. Engelschall]
8835 *) Made RefererIgnore case-insensitive.
8837 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
8840 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
8841 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
8844 *) Improve RFC1413 support. [Bob Beck <beck bofh.ucs.ualberta.ca>]
8846 *) Fix support script `dbmmanage': It was unable to handle some sort
8847 of passwords, especially passwords with "0" chars.
8848 [Ralf S. Engelschall] PR#2242
8850 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
8851 [Ben Laurie] PR#2238
8853 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
8854 library), so CGI handling has been changed to use Win32 native handles
8855 instead of C file descriptors.
8856 [Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
8858 *) The proxy cache would store an incorrect content-length in the cached
8859 file copy after a cache update. That resulted in repeated fetching
8860 of the original copy instead of using the cached copy.
8861 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
8863 *) The Makefiles assumed that DSO files are build via $(LD). This
8864 is broken for two reasons: First we never defined at least LD=ld
8865 somewhere to make sure this works (it was silently assumed that most Make
8866 provide a built-in LD definition - ARGL!) and second using the generic LD
8867 variable is not the truth. Instead a special variable named LD_SHLIB is
8868 reasonable because although "ld" is usually the default, the command for
8869 building DSO files can be "libtool" or even "cc" on some systems.
8870 [Ralf S. Engelschall]
8872 *) Replace the AddVersionPlatform directive with ServerTokens which
8873 provides for more control over the format of the Server:
8874 header line. SERVER_SUBVERSION is no longer supported;
8875 all module should use the ap_add_version_component()
8876 API function instead. [Jim Jagielski]
8878 *) Support for the NCR MP/RAS 3.0
8879 [John Withers <withers semi.kcsc.mwr.irs.gov>]
8881 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
8882 not retrieved in src/Configure and thus was not useable.
8883 [Ralf S. Engelschall]
8885 *) Various Makefile consistency cleanups:
8886 - make OSDIR also automatically be relative to src/ like INCDIR
8887 - SUBDIRS is now generated in src/Makefile only and not in
8888 Makefile.config because it is a local define for this location.
8889 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
8890 any Makefile but make sure that at least the "-K inline" is kept in
8892 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
8893 - updated the dependencies theirself
8894 - removed not existing SHLIB variable from "clean" targets
8895 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
8896 already exists and OBJS_PIC are also just plain objects and have not
8897 directly to do with "shared" things. The only difference is that they
8898 contain PIC. So OBJS_PIC is the more canonical name.
8899 - Updated the Makefile-dependency lines for OBJS_PIC
8900 - Removed the Makefile-dependency line in Configure to avoid double
8902 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
8903 of xxx.lo as GNU libtool does with its PIC objects
8904 - reduce local complexity in modules Makefile.tmpl by moving the last
8905 existing target "depend" to the generation section in Configure, too.
8906 - removed the historical $(SPACER) which was used in the past together
8907 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
8908 is no longer needed.
8909 - force the build and run of the gen_xxx programs under main/ as the
8910 first step before building the objects because it looks cleaner
8911 [Ralf S. Engelschall]
8913 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
8916 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
8919 *) WIN32: Don't force ISAPI headers to finish with \n.
8920 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
8922 *) When opening "configuration" files (like httpd.conf, htaccess
8923 and htpasswd), Apache will not allow them to be non-/dev/null
8924 device files. This closes a DoS hole. At the same time,
8925 we use ap_pfopen to open these files to handle timeouts.
8926 [Jim Jagielski, Martin Kraemer]
8928 *) Apache will now log the reason its httpd children exit if they exit
8929 due to an unexpected signal. (It requires a new porting define,
8930 SYS_SIGLIST, which if defined should point to a list of text
8931 descriptions of the signals available. See PORTING.) [Dean Gaudet]
8933 *) WIN32: chdir() doesn't make sense in a multithreaded environment
8934 like WIN32. Before, Win32 CGI's could have had sporadic failures
8935 if a chdir call from one thread was made between another chdir call
8936 and a spawn in another thread. So, for now don't chdir for CGI scripts
8937 in WIN32. The current CGI "spec" is unclear as to whether it's
8938 necessary. Long-term fix is to either serialize the chdir/spawn combo
8939 or use WIN32 native calls to spawn a process. This temp fix was
8940 necessary to remove this as a showstopper for 1.3's release.
8943 *) Cleanup the suEXEC support in APACI and make it more safe:
8944 1. Add big fat hint in INSTALL about risks and to read the
8945 htdocs/manual/suexec.html document before using the suexec-related
8947 2. Make sure the user has at least provided one --suexec-xxxx option
8948 (specifies suEXEC parameters) in addition to --enable-suexec option.
8949 If only --enable-suexec is given APACI stops with a hint to INSTALL
8950 and htdocs/manual/suexec.html documents.
8951 3. Provide two additional --suexec-xxxx options to make the suEXEC
8952 configuration complete (especially for package maintainers who else
8953 had to patch the source tree) by providing ways to configure minimal
8954 UID/GID and safe PATH, too.
8955 [Ralf S. Engelschall]
8957 *) Cleanup of the `configure --shadow' process:
8958 - make sure the configure script creates its temporary files in the
8959 shadow tree to avoid conflicts with parallel configure runs
8960 - removed unnecessary option "-r" from "rm" call for Makefiles
8961 - make sure the configure scripts creates the shadow-wrapper Makefile
8962 only when no shadow trees already exists
8963 - make sure "make distclean" removes the shadow-wrapper Makefile but only
8964 when no more shadow trees exists
8965 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
8966 as fast (in the past it needed 70sec, now it runs just 38sec)
8967 - make sure CVS does not complain about the created files
8968 Makefille.<gnutriple> and directories src.<gnutriple>
8969 [Ralf S. Engelschall]
8971 *) Added the ap_add_version_component() API routine and the
8972 AddVersionPlatform core directive. The first allows modules to
8973 declare themselves in the Server response header field value,
8974 augmenting the SERVER_SUBVERSION define in the Configuration file
8975 with run-time settings (more useful in a loadable-module environment).
8976 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
8977 into the server version string. [Ken Coar] PR#2056
8979 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
8982 *) Emit the "Accept-Range" header for the default handler.
8983 [Brian Behlendorf] PR#1464
8985 *) Add a note to httpd.conf-dist that apache will on some systems fail
8986 to start when the Group # is set to a negative or large positive value.
8989 *) Make sure the module execution order is correct even when some modules
8990 are loaded under runtime (`LoadModule') via the DSO mechanism:
8991 1. The list of loaded modules is now a dynamically allocated one
8992 and not the original statically list from modules.c
8993 2. The loaded modules are now correctly setup by LoadModule for
8994 later use by the AddModule command.
8995 3. When the DSO mechanism for modules is used APACI's `install'
8996 target now enables all created `LoadModule' lines per default because
8997 this is both already expected by the user _and_ needed to avoid
8998 confusion with the next point and reduces the Makefile.tmpl complexity
8999 4. When the DSO mechanism for modules is used, APACI's `install'
9000 target now additionally makes sure the module list is reconstructed
9001 via a complete `ClearModuleList+AddModule...' entry.
9002 5. The support tool `apxs' now also makes sure an AddModule command
9003 is added in addition to the LoadModule command.
9004 6. The modules.c generation was extended to now contain two
9005 comments to make sure no one is confused by the confusing terminology
9006 of loading/linking (we use load=link+load & link=activate instead of
9007 the obvious load=activate & link=link :-( )
9008 This way now there is no longer a difference under execution time between
9009 statically and dynamically linked modules.
9010 [Ralf S. Engelschall]
9012 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
9013 Big Symbol Renaming. [Ralf S. Engelschall]
9015 *) Add a comment to mod_example.c showing the format of a FLAG command
9018 *) Standardized the time format in mod_status to match that of other
9019 places in the code (e.g. DATE_GMT). PR#1551
9021 *) Fix handling of %Z in timefmt strings for those platforms with no time
9022 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
9025 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
9026 feature compatible with 'UseCanonicalName off' by changing
9027 r->server->server_hostname to ap_get_server_name(). And I changed some
9028 functions which use r->server->port to use ap_get_server_port() instead,
9029 because if there's no Port directive in the config r->server->port is 0.
9032 *) get/set_module_config are trivial enough to be better off inline. Worth
9033 1.5% performance boost. [Dean Gaudet]
9035 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
9036 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
9039 *) [BS2000 security] BS2000 needs an extra authentication to initialize
9040 the task environment to the unprivileged User id. Otherwise CGI scripts
9041 would have a way to gain super user access. [Martin Kraemer]
9043 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
9044 absolute path, only log base name of logging source as is done
9045 in unix. [Martin Kraemer]
9047 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
9048 the encoding type from the Accept-Encoding header (if it's there)
9049 and use it in the response, as that's probably what it'll be expecting.
9050 [<Ronald.Tschalaer psi.ch>]
9052 *) Fix to mod_alias: translate_alias_redir is dealing with
9053 a URI, not a filename, so the check for drive letters for win32
9054 and emx is not necessary. [Dean Gaudet]
9056 *) WIN32: Allow .cmd as an executable extension.
9057 [Kari Likovuori <Kari.Likovuori mol.fi>] PR#2146
9059 *) Make Apache header files, and some variables, C++ friendly.
9060 [Michael Anderson's <mka redes.int.com.mx>]
9062 *) Child processes can now "signal" (by exiting with a status
9063 of APEXIT_CHILDFATAL) the parent process to abort and
9064 shutdown the server if the error in the child process was
9065 fatal enough. [Jim Jagielski]
9067 *) mod_autoindex's find_itme() was sensitive to MIME type case.
9068 [Jim Jagielski] PR#2112
9070 *) Make sure the referer_log and agent_log entries in the default httpd.conf
9071 file are also adjusted for the actual relative installation paths.
9072 [Ralf S. Engelschall] PR#2175
9074 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
9076 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
9079 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
9080 Additionally the checks for finding the vendor DSO library were moved
9081 from mod_so.c to Configure because first it needs $PLAT etc. and second
9082 mod_so already uses an abstraction layer and does not fiddle with the
9083 vendor functions itself.
9084 [Jens-Uwe Mager, Ralf S. Engelschall]
9086 *) PORT: Some optimization defines for NetBSD
9087 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
9089 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
9090 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
9092 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
9093 AIX variants should work fine, too. Even AIX 3.x should work). This is
9094 accomplished by using the free DSO emulation code from Jens-Uwe Mager
9095 which we put into a os/unix/os-dso-aix.c file.
9096 [Ralf S. Engelschall]
9098 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
9099 that we should use NET_SIZE_T == int but the include files force size_t.
9100 [Ralf S. Engelschall]
9102 *) Fix two bugs in select() handling in http_main.c.
9105 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
9106 is unset (as it is in situations like timeouts) where it is unclear
9107 whether errno is set or not. [Martin Kraemer]
9109 *) Just having APACI's localstatedir is too general and not enough for most
9110 of the systems. 1.3b6 again required manual APACI patches by package
9111 maintainers from Red Hat and FreeBSD because for their filesystem layout a
9112 little bit more flexibility in configuring the paths is needed. Hence we
9113 provide three additional configure options (--runtimedir, --logfiledir,
9114 --proxycachedir) which now can be used for more granular adjustments if
9115 --localstatedir is not enough to fit the particular needs. As a nice
9116 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
9117 [Ralf S. Engelschall]
9119 *) Make the install root for "make install" in APACI's Makefile overrideable
9120 by package authors. This way we are even more friendly to package
9121 maintainers (especially Debian and Red Hat) who build for the real prefix
9122 via "configure --prefix=/<real>" but use a different local prefix via
9123 "make root=/tmp/apache install" for rolling the package without bristling
9124 the target location on their system.
9125 [Ralf S. Engelschall]
9127 *) Workaround sed limitations in APACI's configure script by now
9128 substituting in chunks of 50 commands (because for instance HPUX's vendor
9129 sed has a limit of max. 98 commands)
9130 [Ralf S. Engelschall] PR#2136
9132 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
9133 [Ralf S. Engelschall] PR#2140
9135 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
9136 RENAMING process because they are defined as pre-processor macros instead
9137 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
9138 [Ralf S. Engelschall]
9140 *) Workaround braindead AWK's when generating ap_config.h: The split() and
9141 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
9142 [Ralf S. Engelschall] PR#2139
9144 *) Various bugfixes and cleanups for the APACI configure script:
9145 o fix IFS handling for _nested_ situation
9146 o fix Perl interpreter search: take first one found instead of last one
9147 o fix DSO consistency check
9148 o print error messages to stderr instead of stdout
9149 o add install-quiet for --shadow situation to Makefile stub
9150 o reduce complexity by avoiding sed-hacks for rule and module list loops
9151 [Ralf S. Engelschall]
9153 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
9155 *) Make sure the input field separator (IFS) shell variable is explicitly
9156 initialized correctly before _every_ `for' loop and also restored after
9157 the loops. [Ralf S. Engelschall]
9159 *) Make sure that "make install" doesn't overwrite the `mime.types' and
9160 `magic' files from an existing Apache installation. Because people often
9161 customize these for own MIME and content types.
9162 [Ralf S. Engelschall]
9164 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
9165 [Peter Galbavy, Ralf S. Engelschall] PR#2109
9167 *) Fix the path to the ScoreBoardFile in the install-config target, too.
9168 [Ralf S. Engelschall] PR#2105
9170 *) Let "configure" clear out the users parameters (provided as shell
9171 variables) to avoid side-effects in "src/Configure" when the user
9172 exported them (which is not needed, but some users do it).
9173 [Ralf S. Engelschall] PR#2101
9175 *) Provide backward compatibility from some old src/Configuration.tmpl
9176 parameter names to the canonical Autoconf-style shell variable names. For
9177 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
9178 but a hint message is displayed. [Ralf S. Engelschall]
9180 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
9181 CGI scripts from an existing Apache installation.
9182 [Ralf S. Engelschall, Jim Jagielski] PR#2084
9184 *) Make `configure --compat' more "compatible" by first
9185 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
9186 second by making sure the "avoid-bristling-suffix" /apache is not
9187 appended to sysconfdir, datadir, localstatedir and includedir when
9188 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
9190 *) NeXT required strdup() in support/logresolve.c
9191 [Francisco Tomei <fatomei sandburg.unm.edu>] PR#2082
9193 *) AIX required sys/select.h in support/ab.c
9194 [Jens Schleusener <Jens.Schleusener dlr.de>] PR#2081
9196 *) Fix the path to the MimeMagicFile in the install-config target, too.
9197 [Ralf S. Engelschall] PR#2089
9199 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
9201 *) If you start apache with the -S command line option it will dump
9202 out the parsed vhost settings. This is useful for folks trying
9203 to figure out what is wrong with their vhost configuration.
9204 (Other dumps may be added in the future.) [Dean Gaudet]
9206 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
9207 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
9210 *) Because /usr/local/apache is the default prefix the ``configure
9211 --compat'' option no longer has to set prefix, again. This way the
9212 --compat option honors a leading --prefix option. [Lars Eilebrecht]
9214 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
9215 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
9216 to avoid "discard const" warnings. [Ralf S. Engelschall]
9218 *) If a specific handler is set for a file yet the request still
9219 ends up being handled by the default handler, log an error
9220 message before handling it. This catches things such as trying
9221 to use SSIs without mod_include enabled. [Marc Slemko]
9223 *) Fix error logging for the startup case where ap_log_error() still uses
9224 stderr as the target. Now the default log level is honored here, too.
9225 [Ralf S. Engelschall]
9227 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
9228 long" errors when generating the MODULES entry for src/Makefile
9229 [Ben Hyde, Ralf S. Engelschall]
9231 *) Make sure src/Configure doesn't complain about the old directory
9232 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
9234 Changes with Apache 1.3b6
9236 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
9238 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
9239 interface via the similar but proprietary HP/UX shl_xxx-style system
9240 calls. [Ralf S. Engelschall]
9242 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
9243 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
9244 Make. [Ralf S. Engelschall]
9246 *) ++++ THE BIG SYMBOL RENAMING ++++
9247 To avoid symbol clashes with third-party code compiled into the server,
9248 we globally applied the prefix "ap_" to the following classes of
9250 - Apache provided general functions (e.g., ap_cpystrn)
9251 - Public API functions (e.g., palloc, bgets)
9252 - Private functions which we can't make static (because of
9253 cross-object usage) but should be (e.g., new_connection)
9254 For backward source compatibility a new header file named compat.h was
9255 created which provides defines for the old symbol names and can be used
9256 by third-party module authors.
9259 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
9260 problem under SVR4 is that there is no command flag to force the linker
9261 to export the global symbols of the httpd executable therewith they are
9262 available to the DSO's. Instead of problematic hacks like creating a
9263 dummy.so file (containing dummy references to all global symbols) the
9264 httpd binary is linked against, we use a clean trick stolen from Perl 5:
9265 Placing the Apache core code itself into a DSO library named libhttpd.so.
9266 This way the global symbols _HAVE_ to be exported and thus are available
9267 to any manually loaded DSO's under runtime. To reduce the impact to the
9268 user to null we go even further and create a stub httpd executable which
9269 automatically keeps track of the DSO library loading itself and thus
9270 hides the complete mechanism from the user. Although the generation of
9271 this DSO library is automatically triggered for platforms which
9272 essentially need it (mostly all SVR4-derivates) it can be also enabled
9273 manually via the Rule SHARED_CORE. This can be interesting in the future
9274 where we perhaps exploit this libhttpd.so mechanism for providing nifty
9275 features like graceful upgrades, or whatever.
9276 [Ralf S. Engelschall, Martin Kraemer]
9278 *) Build the libraries before building the rest of the tools. [Ben Hyde]
9280 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
9281 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
9282 conventions while "clean" removes only stuff created by "all" targets,
9283 "distclean" additionally removes the stuff from the configuration
9284 process. This way "make distclean" (hence the name) provides a fresh
9285 source tree as it was for distribution.
9286 [Ralf S. Engelschall]
9288 *) Allow top-level (APACI) Makefile to break on build errors
9289 the same way the src/ subtree Makefiles breaks on them by replacing the
9290 initial APACI sed-subdir-display-kludge with a more clean
9291 variable-passing-solution: variable SDP can optionally hold the subdir
9292 prefix which is consistently used for displaying the subdir movement.
9293 This way even the top-level Makefile can stop correctly on errors as the
9294 user expects. [Ralf S. Engelschall]
9296 *) Fixed ordering of argument checks for RewriteBase directive.
9297 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
9299 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
9300 indicating that a module is being compiled for dynamic loading. Also
9301 remove #define IS_MODULE from modules and add SHARED_MODULE define
9302 to the mak/dsp files. [Alexei Kosut]
9304 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
9305 since we are now logging APLOG_WARNING by default. [Roy Fielding]
9307 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
9309 *) Add documentation file and src/Configuration.tmpl entry for the
9310 experimental mod_mmap_static module. Because although it is and marked as
9311 an experimental one it is distributed and thus should be documented and
9312 prepared for configuration the same way as all others modules.
9313 [Ralf S. Engelschall]
9315 *) Add query (-q) option to apxs support tool to be able to manually query
9316 specific settings from apxs. This is needed for instance when you
9317 manually want to access Apache's header files and you need to assemble
9318 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
9319 [Ralf S. Engelschall]
9321 *) Now src/Configure uses a fallback strategy for the shared object support
9322 on platforms where no explicit information is available: If a Perl
9323 installation exists we ask it about its shared object support and if it's
9324 the dlopen-style one we shamelessly guess the compiler and linker flags
9325 for creating shared objects from Perls knowledge. Of course, the user is
9326 warning about what we are doing and informed that he should send us
9327 the guessed flags when they work. [Ralf S. Engelschall]
9329 *) Provide APACI --without-support option to be able to disable the build
9330 and installation of the support tools from the src/support/ area.
9331 Although its useful to have these installed per default we should provide
9332 a way to compile and install without them for backward-compatibility.
9333 [Ralf S. Engelschall]
9335 *) Add of the new APache eXtenSion (apxs) support tool for building and
9336 installing modules into an _already installed_ Apache package through the
9337 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
9338 this approach actually doesn't need the Apache source tree. The
9339 (APACI-installed) server package is enough, because this now includes the
9340 Apache C header files (PREFIX/include) and the new APXS tool
9341 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
9342 module authors to build their Apache modules _OUTSIDE_ the Apache source
9343 tree while avoiding them to fiddle around with the totally platform
9344 dependend way of compiling DSO files. The tool supports all ranges of
9345 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
9346 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
9347 on-the-fly generate a minimalistic Makefile and sample module for the
9348 first step to provide both a quick success event and to demonstrate the
9349 APXS mechanism to module authors. [Ralf S. Engelschall]
9351 *) Fix core dumps in use of CONNECT in proxy.
9352 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
9354 *) Modify the log directives in httpd.conf-dist files to use CustomLog
9355 so that users have examples of how CustomLog can be used.
9358 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
9359 the Apache distribution tree. Until Apache 1.3 there was no real
9360 out-of-the-box batch-capable build and installation procedure for the
9361 complete Apache package. This is now provided by a top-level "configure"
9362 script and a corresponding top-level "Makefile.tmpl" file. The goal is
9363 to provide a GNU Autoconf-style frontend which is capable to both drive
9364 the old src/Configure stuff in batch and additionally installs the
9365 package with a GNU-conforming directory layout. Any options from the old
9366 configuration scheme are available plus a lot of new options for flexibly
9367 customizing Apache. [Ralf S. Engelschall]
9369 *) The floating point ap_snprintf code wasn't threadsafe.
9370 Had to remove the HAVE_CVT macro in order to do threadsafe
9371 calling of the ?cvt() floating point routines. [Dean Gaudet]
9373 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
9375 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
9376 [Jim Jagielski] PR#1901
9378 *) BUG: Configure was using TCC and CC inconsistently. Make sure
9379 Configure knows which CC we are using. [Jim Jagielski]
9381 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
9382 was defined in a parent directory. [Lars Eilebrecht]
9384 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
9385 a generic printf-style routine that can call arbitrary output
9386 routines. Use this to replace http_bprintf.c. Add new routines
9387 psprintf(), pvsprintf() which allocate the exact amount of memory
9388 required for a string from a pool. Use psprintf() to clean up
9389 various bits of code which used ap_snprintf()/pstrdup().
9392 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
9393 ap_snprintf() has different semantics and formatting codes than
9394 snprintf(). [Dean Gaudet]
9396 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
9397 is necessary on at least Solaris where the /etc/rc?.d scripts
9398 are run with these signals ignored, and "SIG_IGN" settings are
9399 maintained across exec().
9400 [Rein Tollevik <reint sys.sol.no>] PR#2009
9402 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
9403 used instead of lstat() and thus this flag didn't work as expected.
9404 [Rein Tollevik <reint sys.sol.no>] PR#2010
9406 *) Fix the proxy pass-through feature of mod_rewrite for the case of
9407 existing QUERY_STRING now that mod_proxy was recently changed because of
9408 the new URL parsing stuff. [Ralf S. Engelschall]
9410 *) A few changes to scoreboard definitions which helps gcc generate
9411 better code. [Dean Gaudet]
9413 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
9414 be a signed bitfield. So mark a few bitfields as signed to
9415 ensure correct code. [Dean Gaudet]
9417 *) The default for HostnameLookups was changed to Off, but there
9418 was a problem and it wasn't taking effect. [Dean Gaudet]
9420 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
9423 *) After a SIGHUP the listening sockets in the parent weren't
9424 properly marked for closure on fork().
9425 [Jürgen Keil <jk tools.de>] PR#2000
9427 *) Allow %2F in two situations: 1) it is in the query part of the URI,
9428 therefore not exposed to %2F -> '/' translations and 2) the request
9429 is a proxy request, so we're not dealing with a local resource anyway.
9430 Without this, the proxy would fail to work for any URL's with
9431 %2f in them (occurs quite often in
9432 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
9434 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
9436 *) Make the shared object compilation command more portable by avoiding
9437 the direct combination of `-c' & `-o' which is not honored by some
9438 compilers like UnixWare's cc. [Ralf S. Engelschall]
9440 *) WIN32: the proxy was creating filenames missing the last four
9441 characters. While this normally doesn't stop anything from
9442 working, it can result in extra collisions.
9443 [Tim Costello <tjcostel socs.uts.edu.au>] PR#1890
9445 *) Now mod_proxy uses the response string (in addition to the response status
9446 code) from the already used FTP SIZE command to setup the Content-Length
9447 header if available. [Ralf S. Engelschall] PR#1183
9449 *) Reanimated the (still undocumented) proxy receive buffer size directive:
9450 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
9451 name was really too generic, added documentation for this directive to
9452 the mod_proxy.html and corrected the hyperlink to it in the
9453 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
9455 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
9456 faster [Martin Kraemer]
9458 *) Make Configure die when you give it an unknown command switch.
9461 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
9462 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
9463 and per default compiled support programs have manual pages - just to
9464 document our stuff a little bit more and to be able to do really
9465 Unix-like installations ;-) [Ralf S. Engelschall]
9467 *) Major cleanups to the Configure script to make it and its generated
9468 Makefiles again readable and maintainable: add SRCDIR option, removed
9469 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
9470 generated sections, consequently added Makefile headers with inheritance
9471 information, added subdir movement messages for easier following where
9472 the build process currently stays (more verbose then standard Make, less
9473 verbose than GNU make), same style to comments in the Configure script,
9474 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
9476 *) Add the new ApacheBench program "ab" to src/support/: This is derived
9477 from the ZeusBench benchmarking program and can be used to determine the
9478 response performance of an Apache installation. This version is
9479 officially licensed with Zeus Technology, Ltd. See the license agreement
9480 statements in <199803171224.NAA24547 en1.engelschall.com> in apache-core.
9481 [Ralf S. Engelschall]
9483 *) API: Various core functions that are definately not part of the API
9484 have been made static, and a few have been marked API_EXPORT. Still
9485 more have been marked CORE_EXPORT and are not intended for general
9486 use by modules. [Doug MacEachern, Dean Gaudet]
9488 *) mod_proxy was not clearing the Proxy-Connection header from
9489 requests; now it does. This did not violate any spec, however
9490 causes poor interactions when you are talking to remote proxies.
9491 [Marc Slemko] PR#1741
9493 *) Various cleanups to the command line interface and manual pages.
9494 [Ralf S. Engelschall]
9496 *) cfg_getline() was not properly handling lines that did not end
9497 with a line termination character. [Marc Slemko] PR#1869, 1909
9499 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
9501 *) Clean up some undocumented behavior of mod_setenvif related to
9502 "merging" two SetEnvIf directives when they match the same header
9503 and regex. Document that mod_setenvif will perform comparisons in
9504 the order they appear in the config file. Optimize mod_setenvif by
9505 doing more work at config time rather than at runtime.
9508 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
9509 to allow for modules to overrule them and to reduce redefinition
9510 warnings [Jim Jagielski]
9512 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
9515 *) Making the hard-coded cross-module function call mime_find_ct() (from
9516 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
9517 checking is really called even for proxy requests except for URLs with
9518 HTTP schemes (because there we can optimize by not running the type
9519 checking hooks due to the fact that the proxy gets the MIME Content-type
9520 from the remote host later). This change cleans up mod_mime by removing
9521 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
9522 especially unbundles mod_proxy and mod_mime. This way they both now can
9523 be compiled as shared objects and are no longer tied together.
9524 [Ralf S. Engelschall]
9526 *) util.c cleanup and speedup. [Dean Gaudet]
9528 *) API: Clarification, pstrndup() will always copy n bytes of the source
9529 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
9531 *) Mark module command_rec and handler_rec structures const so that they
9532 end up in the read-only data section (and are friendlier to systems
9533 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
9535 *) Add check to the "Port" directive to make sure the specified
9536 port is in the appropriate range. [Ben Hyde]
9538 *) Performance improvements to invoke_handler().
9539 [Dmitry Khrustalev <dima bog.msu.su>]
9541 *) Added support for building shared objects even for library-style modules
9542 (which are built from more than one object file). This now provides the
9543 ability to build mod_proxy as a shared object module. Additionally
9544 modules like mod_example are now also supported for shared object
9545 building because the generated Makefiles now no longer assume there is at
9546 least one statically linked module. [Ralf S. Engelschall]
9548 *) API: Clarify usage of content_type, handler, content_encoding,
9549 content_language and content_languages fields in request_rec. They
9550 must always be lowercased; and the strings pointed to shouldn't
9551 be modified (you must copy them to modify them). Fix a few bugs
9552 related to this. [Dean Gaudet]
9554 *) API: Clarification: except for RAW_ARGS, all command handlers can
9555 treat the char * parameters as permanent, and modifiable. There
9556 is no need to pstrdup() them. Clean up some needless pstrdup().
9559 *) Now mod_so keeps track of which module shared objects with which names
9560 are loaded and thus avoids multiple loading and unloading and irritating
9561 error_log messages. [Ralf S. Engelschall]
9563 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
9564 environment variable in the apache core. But that tweaking interferes
9565 with mod_setenv. So don't tweak if the user has specified an explicit
9566 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888
9568 *) rputs() did not calculate r->sent_bodyct properly.
9569 [Siegmund Stirnweiss <siegst kat.ina.de>] PR#1900
9571 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
9572 name, or left unset if this value is unavailable. Apache was setting
9573 it to the IP address when unavailable.
9574 [Tony Finch <fanf demon.net>] PR#1925
9576 *) Various improvements to the configuration and build support for compiling
9577 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
9578 OSF1 support with GCC and vendor compilers was added. This way shared
9579 object support is now provided out-of-the-box for FreeBSD, Linux,
9580 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
9581 [Ralf S. Engelschall]
9583 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
9584 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
9585 and USE_OS2_SCOREBOARD. [Dean Gaudet]
9587 *) Fix one more special locking problem for RewriteMap programs in
9588 mod_rewrite: According to the documentation of flock(), "Locks are on
9589 files, not file descriptors. That is, file descriptors duplicated
9590 through dup(2) or fork(2) do not result in multiple instances of a lock,
9591 but rather multiple references to a single lock. If a process holding a
9592 lock on a file forks and the child explicitly unlocks the file, the
9593 parent will lose its lock.". To overcome this we have to make sure the
9594 RewriteLock file is opened _AFTER_ the childs were spawned which is now
9595 the case by opening it in the child_init instead of the module_init API
9596 hook. [Ralf S. Engelschall] PR#1029
9598 *) Change to Location and LocationMatch semantics. LocationMatch no
9599 longer lets a single slash match multiple adjacent slashes in the
9600 URL. This change is for consistency with RewriteRule and
9601 AliasMatch. Multiple slashes have meaning in URLs that they do
9602 not have in (some) filesystems. Location on the other hand can
9603 be considered a shorthand for a more complicated regex, and it
9604 does match multiple slashes with a single slash -- which is
9605 also consistent with the Alias directive.
9606 [Dean Gaudet] related PR#1440
9608 *) Fix bug with mod_mime_magic causing certain files, including files
9609 of length 0, to result in no response from the server.
9612 *) The Configure script now generates src/include/ap_config.h which
9613 contains the set of defines used when Apache is compiled on a platform.
9614 This file can then be included by external modules before including
9615 any Apache header files in case they are being built separately from
9616 Apache. Along with this change, a couple of minor changes were
9617 made to make Apache's #defines coexist peacefully with any autoconf
9618 defines an external module might have. [Rasmus Lerdorf]
9620 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9621 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9622 chance by the API to initialize its per-server configuration and thus
9623 receives the wrong one from the main server. This is now avoided by
9624 remembering the server together with the config structure while
9625 configuring and later assuming there is no config when we see a
9626 difference between the remembered server and the one calling us.
9627 [Ralf S. Engelschall] PR#1790
9629 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9630 is automatically disabled under configure time when the dbm_xxx functions
9631 are not available. Second, two heavy source code errors in the DBM
9632 support code were fixed. This makes DBM RewriteMap's usable again after
9633 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9635 *) Now all configuration files support Unix-style line-continuation via
9636 the trailing backslash ("\") character. This enables us to write down
9637 complex or just very long directives in a more readable way. The
9638 backslash character has to be really the last character before the
9639 newline and it has not been prefixed by another (escaping) backslash.

9645 *) To deal with modules being compiled and [dynamically] linked
9646 at a different time from the core, the SERVER_VERSION and
9647 SERVER_BUILT symbols have been abstracted through the new
9648 API routines apapi_get_server_version() and apapi_get_server_built().
9651 *) WIN32: Preserve trailing slash in canonical path (and hence
9652 in PATH_INFO). [Paul Sutton, Ben Laurie]
9654 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
9655 depending on the rev of Solaris and what mixture of modules
9656 are in use. So it has been disabled, and Solaris is back to
9657 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9658 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9659 up static content only servers. Or it may fail unpredictably.
9660 [Dean Gaudet] PR#1779, 1854, 1904
9662 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9665 *) API: Rewrite of absoluteURI handling, and in particular how
9666 absoluteURIs match vhosts. Unless a request is a proxy request, a
9667 "http://host" url is treated as if a similar "Host:" header had been
9668 supplied. This change was made to support future HTTP/1.x protocols
9669 which may require clients to send absoluteURIs for all requests.
9671 In order to achieve this change subtle changes were made to the API. In a
9672 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9673 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9674 by the core, modules must set it during the post_read_request or
9675 translate_names phase.
9677 Plus changes to the virtualhost test suite for absoluteURI testing.
9679 This fixes several bugs with the proxy proxying requests to vhosts
9680 managed by the same httpd.
9683 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
9684 code from mod_rewrite. The vhost matching is now performed by a
9685 globally available function matches_request_vhost(). [Dean Gaudet]

9701 *) API: A new source module main/util_uri.c; It contains a routine
9702 parse_uri_components() and friends which breaks a URI into its component
9703 parts. These parts are stored in a uri_components structure called
9704 parsed_uri within each request_rec, and are available to all modules.
9705 Additionally, an unparse routine is supplied which re-assembles the URI
9706 components back to an URI, optionally hiding the username:password@ part
9707 from ftp proxy requests, and other useful routines. Within the structure,
9708 you find on a ready-for-use basis:
9709 scheme; /* scheme ("http"/"ftp"/...) */
9710 hostinfo; /* combined [user[:password]@]host[:port] */
9711 user; /* user name, as in http://user:passwd@host:port/ */
9712 password; /* password, as in http://user:passwd@host:port/ */
9713 hostname; /* hostname from URI (or from Host: header) */
9714 port_str; /* port string (integer representation is in "port") */
9715 path; /* the request path (or "/" if only scheme://host was given) */
9716 query; /* Everything after a '?' in the path, if present */
9717 fragment; /* Trailing "#fragment" string, if present */
9718 This is meant to serve as the platform for *BIG* savings in
9719 code complexity for the proxy module (and maybe the vhost logic).
9722 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
9723 ${map:key}) available for all location where a string is created in
9724 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

9726 possible expansions are consequently usable at all string creation
9727 locations. [Ralf S. Engelschall]
9729 *) Fix initialization of RewriteLogLevel (default now is 0 as documented

9732 completely overridden (default) or completely inherited (when
9733 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

9757 a username can contain when trying to expand it via /etc/passwd.
9758 [Ralf S. Engelschall]
9760 *) The mod_setenvif BrowserMatch backwards compatibility command did not
9761 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
9763 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
9764 type but with a special post-processing for the looked-up value: It
9765 parses it into alternatives according to `|' chars and then only one
9766 particular alternative is chosen randomly (this is an essential
9767 functionality needed for balancing between backend-servers when using
9768 Apache as a Reverse Proxy. The looked up value here is a list of
9769 servers). Second, `int' with the built-in maps named `tolower' and
9770 `toupper' which can be used to map URL parts to a fixed case (this is an
9771 essential feature to fix the case of server names when doing mass
9772 virtual-hosting with the help of mod_rewrite instead of using
9773 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
9774 Jay Soffian <jay cimedia.com>] PR#1631
9776 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
9777 This directive lets Apache adjust the URL in Location-headers on HTTP
9778 redirect responses sent by the remote server. This way the virtually
9779 mapped area is no longer left on redirects and thus by-passed which is
9780 especially essential when running Apache as a reverse proxy.

9783 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
9784 hidden. [Alvaro Martinez Echevarria]
9786 *) Apache will, when started with the -X (single process) debugging flag,

9819 processor. httpd children now unbind themselves from that cpu

9878 *) Sort out problems with canonical filename handling happening too late.

9881 Changes with Apache 1.3b4
9883 *) The module structure was modified to include a *dynamic_load_handle
9884 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
9885 has been bumped accordingly. [Paul Sutton]
9887 *) All BrowserMatch directives mentioned in
9888 htdocs/manual/known_client_problems.html are in the default
9889 configuration files. [Lars Eilebrecht]
9891 *) MiNT port update. [Jan Paul Schmidt]
9893 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
9894 equivalent, similarly for x-compress and compress. Apache
9895 now ignores a leading x- when comparing encodings. It also
9896 preserves the encoding the client requests (for example if
9897 it requests x-gzip, then Apache will respond with x-gzip
9898 in the Content-Encoding header).
9899 [Ronald Tschalaer <Ronald.Tschalaer psi.ch>] PR#1772
9901 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
9903 *) Added mod_so module to support dynamic loading of modules on Unix
9904 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
9905 instead of AddModule in Configuration to build shared modules
9906 [Sameer Parekh, Paul Sutton]
9908 *) Minor cleanups to r->finfo handling in some modules.
9911 *) Abstract read()/write() to ap_read()/ap_write().
9912 Makes it easier to add other types of IO code such as SFIO.
9915 *) API: Generalize default_port manipulations to make support of
9916 different protocols easier. [Ben Laurie, Randy Terbush]
9918 *) There are many cases where users do not want Apache to form
9919 self-referential urls using the "canonical" ServerName and Port.
9920 The new UseCanonicalName directive (default on), if set to off
9921 will cause Apache to use the client-supplied hostname and port.

9923 prototype; and the addition of get_server_name() and

9926 PR#315, 459, 485, 1433
9928 *) Yet another rearrangement of the source tree.. now all the common
9929 header files are in the src/include directory. The -Imain -Iap
9930 references in Makefiles have been changed to the simpler -Iinclude
9931 instead. In addition to simplifying the build a little bit, this
9932 also makes it clear when a module is referencing something in a
9933 other than kosher manner (e.g., the proxy including mod_mime.h).
9934 Module-private header files (the proxy, mod_mime, the regex library,
9935 and mod_rewrite) have not been moved to src/include; nor have
9936 the OS-abstraction files. [Ken Coar]
9938 *) Fix a bug where r->hostname didn't have the :port stripped
9939 from it. [Dean Gaudet]
9941 *) Tweaked the headers_out table size, and the subprocess_env
9942 table size guess in rename_original_environment(). Added
9943 MAKE_TABLE_PROFILE which can help discover make_table()
9944 calls that use too small an initial guess, see alloc.c.
9947 *) Options and AllowOverride weren't properly merging in the main
9948 server setting inside vhosts (only an issue when you have no
9949 <Directory> or other section containing an Options that affects
9950 a request). Options +foo or -foo in the main_server wouldn't
9951 affect the main_server's lookup defaults. [Dean Gaudet]
9953 *) Variable 'cwd' was being used pointlessly before being set.
9956 *) r->allowed handling cleaned up in the standard modules.
9959 *) Some case-sensitivity issues cleaned up to be consistent with
9960 RFC2068. [Dean Gaudet]
9962 *) SIGURG doesn't exist everywhere.
9963 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
9965 *) mod_unique_id was erroneously generating a second unique id when
9966 an internal redirect occured. Such redirects occur, for example,
9967 when processing a DirectoryIndex match. [Dean Gaudet]
9969 *) API: table_add, table_merge, and table_set include implicit pstrdup()
9970 of the key and value. But in many cases this is not required
9971 because the key/value is a constant, or the value has been built
9972 by pstrcat() or other similar means. New routines table_addn,
9973 table_mergen, and table_setn have been added to the API, these
9974 routines do not pstrdup() their arguments. The core code and
9975 standard modules were changed to take advantage of these routines.
9976 The resulting server is up to 20% faster in some situations.
9978 Note that it is easy to get code subtly wrong if you pass a key/value
9979 which is in a pool other than the pool of the table. The only
9980 safe thing to do is to pass key/values which are in the pool of
9981 the table, or in one of the ancestors of the pool of the table.
9982 i.e. if the table is part of a subrequest, a value from the main
9983 request's pool is OK since the subrequest pool is a sub_pool of the
9984 main request's pool (and therefore has a lifespan at most as long as
9985 the main pool). There is debugging code which can detect improper
9986 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
9987 [Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet]
9989 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
9990 which don't exist on disk more gracefully; handles vhosts properly.
9991 Update documentation to reflect the code -- if there's no
9992 MimeMagicFile directive then the module is not enabled.
9995 *) PORT: Some older *nix dialects cannot automatically start scripts
9996 which begin with a #! interpreter line (the shell starts the scripts
9997 appropriately on these platforms). Apache now supports starting of
9998 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
9999 [Martin Kraemer, with code from Peter Wemm <peter zeus.dialix.oz.au>
10002 *) API: "typedef array_header table" removed from alloc.h, folks should
10003 have been writing to use table as if it were an opaque type, but even
10004 some standard modules got this wrong. By changing the definition
10005 to "typedef struct table table" module authors will receive compile
10006 time warnings that they're doing the wrong thing. This change
10007 facilitates future changes with more sophisticated table
10008 structures. Specifically, module authors should be using table_elts()
10009 to get access to an array_header * for the table. [Dean Gaudet]
10011 *) API: Renamed new_connection() to avoid namespace collision with LDAP
10012 library routines. [Ken Coar, Rasmus Lerdorf]
10014 *) WIN32: mod_speling is now available on the Win32 platform.
10017 *) For clarity the following compile time definition was changed:
10019 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
10021 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
10022 and not be a general notice that the OS has mmap(). Now the
10023 HAVE_MMAP/SHMGET #defines strictly are informational that the
10024 OS has that method of shared memory; the type to use for
10025 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
10026 and USE_SHMGET_SCOREBOARD). This allows outside modules to
10027 determine if shared memory is available and allows Apache
10028 to determine the best method to use for the scoreboard.
10031 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
10032 as do various earlier versions. It should be safe on all versions.
10033 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
10034 the slack code. A few other cleanups for Unixware.

10040 *) When die() happens we need to eat any request body if one exists.
10041 Otherwise we can't continue with a keepalive session. This shows up
10042 as a POST problem with MSIE 4.0, typically against pages which are
10043 authenticated. [Roy Fielding] PR#1399
10045 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization

10056 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
10057 The choice of flock vs. fcntl was made based on timings which showed that
10058 even on non-NFS, non-exported filesystems fcntl() was an order of
10059 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
10060 that single socket users will see no difference. [Dean Gaudet] PR#467

10082 *) Some const declarations in mod_imap.c that were added for debugging
10083 purposes caused some compilers heartburn without adding any
10084 significant value, so they've been removed. [Ken Coar]
10086 *) The src/main/*.h header files have had #ifndef wrappers added to
10087 insulate them against duplicate calls if they get included through
10088 multiple paths (e.g., in .c files as well as other .h files).
10091 *) The libap routines now have a header file for their prototypes,
10092 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
10094 *) mod_autoindex with a plaintext header file would emit the <PRE>
10095 start-tag before the HTML preamble, rather than after the preamble
10096 but before the header file contents. [John Van Essen <jve gamers.org>]
10099 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
10100 only an issue on systems without a MAXDNAME define or where
10101 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
10103 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
10104 is used to read various types of files such as htaccess and
10105 htpasswd files. [Marc Slemko]
10107 *) SECURITY: Ensure that the buffer returned by ht_time is always
10108 properly null terminated. [Marc Slemko]

10120 *) For maximum portability, the environment passed to CGIs should
10121 only contain variables whose names match the regex
10122 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
10123 underscores over any character outside the regex. This
10124 affects HTTP_* variables, in a way that should be backward
10125 compatible for all the standard headers; and affects variables
10126 set with SetEnv/BrowserMatch and similar directives.

10212 *) send_fd_length() did not calculate total_bytes_sent properly.
10213 [Ben Reser <breser regnow.com>] PR#1366
10215 *) The bputc() macro was not properly integrated with the chunking
10216 code; in many cases modules using bputc() could cause completely
10217 bogus chunked output. (Typically this will show up as problems
10218 with Internet Explorer 4.0 reading a page, but other browsers
10219 having no problem.) [Dean Gaudet]
10221 *) Create LARGE_WRITE_THRESHOLD define which determines how many
10222 bytes have to be supplied to bwrite() before it will consider
10223 doing a writev() to assemble multiple buffers in one system
10224 call. This is critical for modules such as mod_include,
10225 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
10226 strings in some cases. The result would be extra effort
10227 setting up writev(), and in many cases extra effort building
10228 chunks. The default is 31, it can be overriden at compile
10229 time. [Dean Gaudet]

10338 This turns out to be a bug in Winsock - select() doesn't always

10341 *) Directives owned by http_core can now use the new check_cmd_context()
10342 routine to ensure that they're not being used within a container
10343 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
10345 *) PORT: Recent changes made it necessary to add explicit prototype
10346 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
10348 *) It was necessary to distinguish between resources which are
10349 allocated in the parent, for cleanup in the parent, and resources
10350 which are allocated in each child, for cleanup in each child.
10351 A new pool was created which is passed to the module child_init
10352 and child_exit functions; modules are free to register per-child
10353 cleanups there. This fixes a bug with reliable piped logs.
10356 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
10357 unless it was also doing FancyIndexes, but it displayed the
10358 HeaderName file at the top under all circumstances. It now shows
10359 the ReadmeName file for simple indices, too, as it should.
10362 *) http_core was mmap()ing even in cases where it wasn't going to
10363 read the file. [Ben Hyde <bhyde gensym.com>]
10365 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
10366 Now the rewriting engine (the heart of mod_rewrite) is organized more
10367 straight-forward, first time well documented and reduced to the really
10368 essential parts. All redundant cases were stripped off and processing now
10369 is the same for both per-server and per-directory context with only a
10370 minimum difference (the prefix stripping in per-dir context). As a
10371 side-effect some subtle restrictions and two recently discovered problems
10372 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
10373 context and restrictions on the substitution URL on redirects.
10374 Additionally some minor source cleanups were done.

10529 Changes with Apache 1.3b2 (there is no 1.3b1)
10531 *) TestCompile was not passing $LIBS [Dean Gaudet]
10533 *) Makefile.tmpl was not using $CFLAGS in the link phase.
10536 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
10537 rudimentary memory debugger which can be used on live servers with
10538 low impact -- it sets all allocated and freed memory bytes to 0xa5.
10539 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
10540 and free() for each object. This is far more expensive and should
10541 only be used for testing with tools such as Electric Fence and
10542 Purify. See main/alloc.c for more details. [Dean Gaudet]
10544 *) Configure uses a sh trap and didn't set its exitcode properly.
10545 [Dean Gaudet] PR#1159
10547 *) Yet another vhost revamp. Add the NameVirtualHost directive which
10548 explicitly lists the ip:port pairs that are to be used for name-vhosts.
10549 From a given ip:port, regardless what the Host: header is, you can
10550 only reach the vhosts defined on that ip:port. The precedence of
10551 vhosts was reversed to match other precedences in the config --
10552 the earlier vhosts override the later vhosts. All vhost matching was
10553 moved into http_vhost.[ch]. [Dean Gaudet]
10555 *) ap_inline can be used to force inlining. GNUC __attribute__() can
10556 be used for whatever reason is appropriate (i.e. format() warnings
10557 for printf style functions). Both are enabled only with
10558 gcc >= 2.7.x (so that we have fewer support issues with older
10559 versions). [Dean Gaudet]
10561 *) Fix support for Proxy Authentication (we were testing the response
10562 status too early). [Marc Slemko]
10564 *) CoreDumpDirectory directive directs where the core file is
10565 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
10566 received. [Marc Slemko, Dean Gaudet]
10568 *) PORT: Support for Atari MINT.
10569 [Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
10571 *) When booting, apache will now detach itself from stdin, stdout,
10572 and stderr. stderr will not be detached until after the config
10573 files have been read so you will be able to see initial error
10574 messages. After that all errors are logged in the error_log.
10575 This makes it more convenient to start apache via rsh, ssh,
10576 or crontabs. [Dean Gaudet] PR#523
10578 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10579 Also removed the auto-generated link to www.apache.org that was the
10580 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10582 *) send_fb would not detect aborted connections in some situations.
10585 *) mod_include would use uninitialized data when parsing certain
10586 expressions involving && and ||. [Brian Slesinsky] PR#1139
10588 *) mod_imap should only handle GET methods. [Jay Bloodworth]
10590 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10592 *) mod_autoindex improperly counted &escapes; as more than one
10593 character in the description. It also improperly truncated
10594 descriptions that were exactly the maximum length.
10597 *) RedirectMatch was not properly escaping the result (PR#1155). Also
10598 "RedirectMatch /advertiser/(.*) $1" is now permitted.
10601 *) mod_include now uses symbolic names to check for request success
10602 and return HTTP errors, and correctly handles all types of
10603 redirections (previously it only did temporary redirect correctly).
10604 [Ken Coar, Roy Fielding]
10606 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10607 r->filename. Since those two are meant to be in sync with each other
10608 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]

10617 reporting a select error over and over.

10620 *) Fixed error in proxy_util.c when looping through multiple host IP
10621 addresses. [Lars Eilebrecht] PR#974
10623 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10624 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10625 bytes before writing, but it will never split a log entry across a
10626 buffer boundary. [Dean Gaudet]
10628 *) API: the short_score record has been split into two pieces, one which
10629 the parent writes on, and one which the child writes on. As part of
10630 this change the get_scoreboard_info() function was removed, and
10631 scoreboard_image was exported. This change fixes a race condition
10632 in file based scoreboard systems, and speeds up changes involving the
10633 scoreboard in earlier 1.3 development. [Dean Gaudet]
10635 *) API: New register_other_child() API (see http_main.h) which allows
10636 modules to register children with the parent for maintenance. It
10637 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10639 *) API: New piped_log API (see http_log.h) which implements piped logs,
10640 and will use register_other_child to implement reliable piped logs
10641 when it is available. The reliable piped logs part can be disabled
10642 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10643 logs is only available on Unix. [Dean Gaudet]
10645 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10646 meets_conditions(). This allows conditional HTTP selection to be
10647 handled separately from the storing of the header fields, and provides
10648 the ability for CGIs to set their own ETags for conditional checking.
10649 [Ken Coar, Roy Fielding] PR#895
10651 *) Changes to mod_log_config to allow naming of format strings.
10652 Format nicknames are defined with "LogFormat fmt nickname", and can
10653 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
10656 *) New module, "mod_speling", which can help find files even when
10657 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
10659 *) API: New function child_terminate() triggers the child process to
10660 exit, while allowing the child finish what it needs to for the
10661 current request first.
10662 [Doug MacEachern, Alexei Kosut]
10664 *) Windows now defaults to using full status reports with mod_status.
10665 [Alexei Kosut] PR #1094
10667 *) *Really* disable all mod_rewrite operations if the engine is off.
10668 Some things (like RewriteMaps) were checked/performed even if they
10669 weren't supposed to be. [Ken Coar] PR #991
10671 *) Implement a new timer scheme which eliminates the need to call alarm() all
10672 the time. Instead a counter in the scoreboard for each child is used to
10673 show when the child has made forward progress. The parent samples this
10674 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10675 progress has been made in the timeout period. This reduces the static
10676 request best-case syscall count to 22 from 29. This scheme is only
10677 used by systems with memory-based scoreboards. [Dean Gaudet]
10679 *) The proxy now properly handles CONNECT requests which are sent
10680 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10682 *) A script called apachectl has been added to the support
10683 directory. This script allows you to do things such as
10684 "apachectl start" and "apachectl restart" from the command
10685 line. [Marc Slemko]
10687 *) Modules and core routines are now put into libraries, which
10688 simplifies the link line tremendously (among other advantages).
10691 *) Some of the MD5 names defined in Apache have been renamed to have
10692 an `ap_' prefix to avoid conflicts with routines supplied by
10693 external libraries. [Ken Coar]
10695 *) Removal of mod_auth_msql.c from the distribution. There are many
10696 other options for databases today. Rather than offer one option,
10697 offer none at this time. mod_auth_msql and other SQL database
10698 authentication modules can be found at the Apache Module Registry.
10699 http://modules.apache.org/ It would be nice to offer a generic
10700 mod_auth_sql option in the near future.
10702 *) PORT: BeOS support added [Alexei Kosut]
10704 *) Configure no longer accepts the -make option, since it creates
10705 Makefile on the fly based on Makefile.tmpl and Configuration.
10707 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
10708 of forcibly killing off all its processes and exiting without
10709 cleaning up. [Alexei Kosut]
10711 *) API: A new field in the request_rec, r->mtime, has been added to
10712 avoid gratuitous parsing of date strings. It is intended to hold
10713 the last-modified date of the resource (if applicable). An
10714 update_mtime() routine has also been added to advance it if
10715 appropriate. [Roy Fielding, Ken Coar]
10717 *) SECURITY: If a htaccess file can not be read due to bad permissions,
10718 deny access to the directory with a HTTP_FORBIDDEN. The previous
10719 behavior was to ignore the htaccess file if it could not be read.
10720 This change may make some setups with unreadable htaccess files
10721 stop working. [Marc Slemko] PR#817
10723 *) Add aplog_error() providing a mechanism to define levels of
10724 verbosity to the server error logging. This addition also provides
10725 the ability to log errors using syslogd. Error logging is configurable
10726 on a per-server basis using the LogLevel directive. Conversion
10727 of log_*() in progress. [Randy Terbush]
10729 *) Further enhance aplog_error() to not log filename, line number, and
10730 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
10732 *) WIN32: Canonicalise filenames under Win32. Short filenames are
10733 converted to long ones. Backslashes are converted to forward
10734 slashes. Case is converted to lower. Parts of URLs that do not
10735 correspond to files are left completely alone. [Ben Laurie]
10737 *) PORT: 2 new OSs added to the list of ports:
10738 Encore's UMAX V: Arieh Markel <amarkel encore.com>
10739 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
10741 *) Add the server version (SERVER_VERSION macro) to the "server
10742 configured and running" entry in the error_log. Also build an
10743 object file at link-time that contains the current time
10744 (SERVER_BUILT global const char[]), and include that in the
10745 message. [Ken Coar]
10747 *) Set r->headers_out when sending responses from the proxy.
10748 This fixes things such as the logging of headers sent from
10749 the proxy. [Marc Slemko] PR#659
10751 *) support/httpd_monitor is no longer distributed because the
10752 scoreboard should not be file based if at all possible. Use
10753 mod_status to see current server snapshot.
10755 *) (set_file_slot): New function, allowing auth directives to be
10756 independent of the server root, so the server documents can be
10757 moved to a different directory or machine more easily.
10758 [David J. MacKenzie]

10761 to log. This supports coexistence with other logging modules,
10762 such as the custom one that UUNET uses. [David J. MacKenzie]
10764 *) Check for titles in server-parsed HTML files.
10765 Ignore leading newlines and returns in titles. The old behavior
10766 of replacing a newline after <title> with a space causes the
10767 title to be misaligned in the listing. [David J. MacKenzie]
10769 *) Change mod_cern_meta to be configurable on a per-directory basis.
10770 [David J. MacKenzie]
10772 *) Add 'Include' directive to allow inclusion of configuration
10773 files within configuration files. [Randy Terbush]
10775 *) Proxy errors on connect() are logged to the error_log (nothing
10776 new); now they include the IP address and port that failed
10777 (*that's* new). [Ken Coar, Marc Slemko] PR#352
10779 *) Various architectures now define USE_MMAP_FILES which causes
10780 the server to use mmap() for static files. There are two
10781 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
10782 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
10783 number of bytes written in one cycle from a single mmap()d object,
10784 default 32768). [Dean Gaudet]
10786 *) API: Added post_read_request API phase which is run right after reading
10787 the request from a client, or right after an internal redirect. It is
10788 useful for modules setting environment variables that depend only on
10789 the headers/contents of the request. It does not run during subrequests
10790 because subrequests inherit pretty much everything from the main
10791 request. [Dean Gaudet]
10793 *) Added mod_unique_id which is used to generate a unique identifier for
10794 each hit, available in the environment variable UNIQUE_ID.
10797 *) init_modules is now called after the error logs have been opened. This
10798 allows modules to emit information messages into the error logs.
10801 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10802 information for case where proxy module is not available. [Marc Slemko]
10804 *) PORT: Apache has need for mutexes to serialize its children around
10805 accept. In prior versions either fcntl file locking or flock file
10806 locking were used. The method is chosen by the definition of
10807 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
10808 and FLOCK for flock(). New options have been added:
10809 - SYSVSEM to use System V style semaphores
10810 - PTHREAD to use POSIX threads (appears to work on Solaris only)
10811 - USLOCK to use IRIX uslock
10812 Based on timing various techniques, the following changes were made
10814 - Linux 2.x uses flock instead of fcntl
10815 - Solaris 2.x uses pthreads
10816 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
10817 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
10818 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
10819 Martijn Koster <m.koster pobox.com>]
10821 *) PORT: The semantics of accept/select make it very desirable to use
10822 mutexes to serialize accept when multiple Listens are in use. But
10823 in the case where only a single socket is open it is sometimes
10824 redundant to serialize accept(). Not all unixes do a good job with
10825 potentially dozens of children blocked on accept() on the same
10826 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
10827 the server will avoid serialization when listening on only one socket,
10828 and use serialization when listening on multiple sockets.
10829 [Dean Gaudet] PR#467
10831 *) Configure changes: TestLib replaced by TestCompile, which has
10832 some additional capability (such as doing a sanity check of
10833 the compiler and flags selected); the version of Solaris is now
10834 available via the #define value of SOLARIS2; IRIX n32bit libs
10835 now supported and selectable by new Configuration Rule: IRIXN32;
10836 We no longer default to -O2 optimization. [Jim Jagielski]
10838 *) Updated Configure: Configuration now uses AddModule to specify
10839 module source or binary file location, relative to src directory.
10840 Modules can be dropped into modules/extra, or in their own
10841 directory, and modules can come with a Makefile or Configure can
10842 create one. Modules can add compiler or library information to
10843 generated Makefiles. [Paul Sutton]
10845 *) Source core re-organisation: distributed modules are now in
10846 modules/standard. All other source code is in main. OS-specific
10847 code is in os/{unix,emx,win32} directories. [Paul Sutton]
10849 *) mod_browser has been removed, since it's replaced by mod_setenvif.
10852 *) Fix another long-standing bug in sub_req_lookup_file where it would
10853 happily skip past access checks on subdirectories looked up with
10854 relative paths. (It's used by mod_dir, mod_negotiation,
10855 and mod_include.) [Dean Gaudet]
10857 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
10858 N is the number of <Directory> sections, and M is the number of
10859 components in the filename of an object.
10861 To achieve this optimization the following config changes were made:
10862 - Wildcards (* and ?, not the regex forms) in <Directory>s,
10863 <Files>s, and <Location>s now treat a slash as a special
10864 character. For example "/home/*/public_html" previously would
10865 match "/home/a/andrew/public_html", now it only matches things
10866 like "/home/bob/public_html". This mimics /bin/sh behaviour.
10867 - It's possible now to use [] wildcarding in <Directory>, <Files>
10869 - Regex <Directory>s are applied after all non-regex <Directory>s.
10873 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
10874 and corrupted paths. [Dean Gaudet]
10876 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
10877 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
10878 be accessed now via backreferences $1..$9 in RewriteConds test-against
10879 strings in addition to RewriteRules subst string. Second the grouped
10880 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
10881 via backreferences %1..%9 both in following RewriteCond test-against
10882 strings and RewriteRules subst string. This provides maximum flexibility
10883 through the use of backreferences.
10884 Additionally the rewriting engine was cleaned up by putting common
10885 code to the new expand_backrefs_inbuffer() function.
10886 [Ralf S. Engelschall]
10888 *) When merging the main server's <Directory> and <Location> sections into
10889 a vhost, put the main server's first and the vhost's second. Otherwise
10890 the vhost can't override the main server. [Dean Gaudet] PR#717
10892 *) The <Directory> code would merge and re-merge the same section after
10893 a match was found, possibly causing problems with some modules.
10896 *) ip-based vhosts are stored and queried using a hashing function, which
10897 has been shown to improve performance on servers with many ip-vhosts.
10898 Some other changes had to be made to accommodate this:
10899 - the * address for vhosts now behaves like _default_
10900 - the matching process now is:
10901 - match an ip-vhost directly via hash (possibly matches main
10903 - if that fails, just pretend it matched the main server
10904 - if so far only the main server has been matched, perform
10905 name-based lookups (ServerName, ServerAlias, ServerPath)
10906 *only on name-based vhosts*
10907 - if they fail, look for _default_ vhosts
10908 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
10910 *) dbmmanage overhaul:
10911 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
10912 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
10913 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
10914 - provide better seed for rand
10915 - prompt for password as per getpass(3) (turn off echo, read from
10917 - use "newstyle" crypt based on $Config{osname} ($^O)
10918 - will not add a user if already in database, use new `update' command
10920 - added `check' command to check a users' password
10921 - added `import' command to convert existing password text-files or
10922 dbm files exported with `view'
10923 - more descriptive usage, general cleanup, 'use strict' clean, etc.
10926 *) Added psocket() which is a pool form of socket(), various places within
10927 the proxy weren't properly blocking alarms while registering the cleanup
10928 for its sockets. bclose() now uses pclose() and pclosesocket(). There
10929 was a bug where the client socket was being close()d twice due a still
10930 registered cleanup. [Dean Gaudet]
10932 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
10935 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
10936 [Jason Venner <jason idiom.com>] PR#667
10938 *) Enable ``=""'' for RewriteCond directives to match against
10939 the empty string. This is the preferred way instead of ``^$''.
10940 [Ralf S. Engelschall]
10942 *) Fixed an infinite loop in mod_imap for references above the server root
10943 [Dean Gaudet] PR#748
10945 *) mod_proxy now has a ReceiveBufferSize directive, similar to
10946 SendBufferSize, so that the TCP window can be set appropriately
10947 for LFNs. [Phillip A. Prindeville]
10949 *) mod_browser has been replaced by the more general mod_setenvif
10950 (courtesy of Paul Sutton). BrowserMatch* directives are still
10951 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
10952 UnSetEnvIfZero directives. [Ken Coar]
10954 *) "HostnameLookups double" forces double-reverse DNS to succeed in
10955 order for remote_host to be set (for logging, or for the env var
10956 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
10959 *) mod_access overhaul:
10960 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
10961 and cidr syntax (i.e. 10.1.0.0/16). PR#762
10962 - Critical path was sped up by pre-computing a few things at config time.
10963 - The undocumented syntax "allow user-agents" was removed,
10964 the replacement is "allow from env=foobar" combined with mod_browser.
10965 - When used with hostnames it now forces a double-reverse lookup
10966 no matter what the directory settings are. This double-reverse
10967 doesn't affect any of the other routines that use the remote
10968 hostname. In particular it's still passed to CGIs and the log
10969 without the double-reverse check. Related PR#860.
10972 *) When a large bwrite() occurs (larger than the internal buffer size),
10973 while there is already something in the buffer, apache will combine
10974 the large write and the buffer into a single writev(). (This is
10975 in anticipation of using mmap() for reading files.)
10978 *) In obscure cases where a partial socket write occurred while chunking,
10979 Apache would omit the chunk header/footer on the next block. Cleaned
10980 up other bugs/inconsistencies in error conditions in buff.c. Fixed
10981 a bug where a long pause in DNS lookups could cause the last packet
10982 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
10984 *) API: Added child_exit function to module structure. This is called
10985 once per "heavy-weight process" just before a server child exit()'s
10986 e.g. when max_requests_per_child is reached, etc.
10987 [Doug MacEachern, Dean Gaudet]
10989 *) mod_include cleanup showed that handle_else was being used to handle
10990 endif. It didn't cause problems, but it was cleaned up too.
10993 *) mod_cern_meta would attempt to find meta files for the directory itself
10994 in some cases, but not in others. It now avoids it in all cases.
10997 *) mod_mime_magic would core dump if there was a decompression error.
10998 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
11000 *) PORT: some variants of DGUX require -lsocket -lnsl
11001 [Alexander L Jones <alex systems-options.co.uk>] PR#732
11003 *) mod_autoindex now allows sorting of FancyIndexed directory listings
11004 by the various fields (name, size, et cetera), either in ascending
11005 or descending order. Just click on the column header. [Ken Coar]
11007 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
11008 CPUs like the Alpha. Apache still stores ints in pointers, but that's
11009 the relatively safe direction. [Dean Gaudet] PR#344
11011 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
11012 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
11014 *) child_main avoids an unneeded call to select() when there is only one
11015 listening socket. [Dean Gaudet]
11017 *) In the event that the server is starved for idle servers it will
11018 spawn 1, then 2, then 4, ..., then 32 servers each second,
11019 doubling each second. It'll also give a warning in the errorlog
11020 since the most common reason for this is a poor StartServers
11021 setting. The define MAX_SPAWN_RATE can be used to raise/lower
11022 the maximum. [Dean Gaudet]
11024 *) Apache now provides an effectively unbuffered connection for
11025 CGI scripts. This means that data will be sent to the client
11026 as soon as the CGI pauses or stops output; previously, Apache would
11027 buffer the output up to a fixed buffer size before sending, which
11028 could result in the user viewing an empty page until the CGI finished
11029 or output a complete buffer. It is no longer necessary to use an
11030 "nph-" CGI to get unbuffered output. Given that most CGIs are written
11031 in a language that by default does buffering (e.g. perl) this
11032 shouldn't have a detrimental effect on performance.
11034 "nph-" CGIs, which formerly provided a direct socket to the client
11035 without any server post-processing, were not fully compatible with
11036 HTTP/1.1 or SSL support. As such they would have had to implement
11037 the transport details, such as encryption or chunking, in order
11038 to work properly in certain situations. Now, the only difference
11039 between nph and non-nph scripts is "non-parsed headers".
11040 [Dean Gaudet, Sameer Parekh, Roy Fielding]
11042 *) If a BUFF is switched from buffered to unbuffered reading the first
11043 bread() will return whatever remained in the buffer prior to the
11044 switch. [Dean Gaudet]
11046 Changes with Apache 1.3a1
11048 *) Added another Configure helper script: TestLib. It determines
11049 if a specified library exists. [Jim Jagielski]
11051 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
11052 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
11055 *) PORT: Some architectures use size_t for various lengths in network
11056 functions such as accept(), and getsockname(). The definition
11057 NET_SIZE_T is used to control this. [Dean Gaudet]
11059 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
11060 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
11061 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
11063 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
11064 [Igor N Kovalenko <infoh mail.wplus.net>]
11066 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11067 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11068 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11069 [Dean Gaudet] related PR#875
11071 *) API: Correct child_init() slot declaration from int to void, to
11072 match the init() declaration. Update mod_example to use the new
11075 *) added transport handle slot (t_handle) to the BUFF structure
11078 *) get_client_block() returns wrong length if policy is
11079 REQUEST_CHUNKED_DECHUNK.

11087 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
11089 *) AddModuleInfo directive for mod_info which allows you to annotate
11090 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
11092 *) Added NoProxy directive to avoid using ProxyRemote for selected
11093 addresses. Added ProxyDomain directive to cause unqualified
11094 names to be qualified by redirection.
11095 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
11097 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
11098 header to the remote host in the proxy. [Sameer Parekh and
11101 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
11102 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
11103 URLs, fixed rewritelog(), fixed forced response code handling on
11104 redirects from within .htaccess files, disabled pipe locking under
11105 braindead SunOS 4.1.x, allow env variables to be set even on rules with
11106 no substitution, bugfixed situations where HostnameLookups is off, made
11107 mod_rewrite more thread-safe for NT port and fixed problem when creating
11108 an empty query string via "xxx?".
11109 This update also removes the copyright of Ralf S. Engelschall,
11110 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
11111 exclusively copyrighted by the Apache Group now. This happened because
11112 the author now has gifted mod_rewrite exclusively to the Apache Group and
11113 no longer maintains an external version.
11114 [Ralf S. Engelschall]
11116 *) API: Added child_init function to module structure. This is called
11117 once per "heavy-weight process" before any requests are handled.
11118 See http_config.h for more details. [Dean Gaudet]
11120 *) Anonymous_LogEmail was logging on each subrequest.
11121 [Dean Gaudet] PR#421, 868
11123 *) API: Added is_initial_req() which tests if the request being
11124 processed is the initial request, or a subrequest.
11127 *) Extended SSI (mod_include) now handles additional relops for
11128 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
11130 *) Configure fixed to correctly propagate user-selected options and
11131 settings (such as CC and OPTIM) to Makefiles other than
11132 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
11134 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
11135 directory indices to start with the contents of the HeaderName file
11136 if there is one. If there isn't one, the behaviour is unchanged.
11137 [Ken Coar, Roy Fielding, Andrey A. Chernov]
11139 *) WIN32: Modules can now be dynamically loaded DLLs using the
11140 LoadModule/LoadFile directives. Note that module DLLs must be
11141 compiled with the multithreaded DLL version of the runtime library.
11142 [Alexei Kosut and Ben Laurie]
11144 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
11145 This allows the admin to completely remove automatic indexing
11146 from the server, while still supporting the basic functions of
11147 trailing-slash redirects and DirectoryIndex files. Note that if
11148 you're carrying over an old Configuration file and you use directory
11149 indexing then you'll want to add:
11151 Module autoindex_module mod_autoindex.o
11153 before mod_dir in your Configuration. [Dean Gaudet]
11155 *) popendir/pclosedir created to properly protect directory scanning.
11156 [Dean Gaudet] PR#525
11158 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
11159 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
11160 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
11163 *) The AccessFileName directive can now take more than one filename.
11164 ["Lou D. Langholtz" <ldl usi.utah.edu>]
11166 *) The new mod_mime_magic can be used to "magically" determine the type
11167 of a file if the extension is unknown. Based on the unix file(1)
11168 command. [Ian Kluft <ikluft cisco.com>]
11170 *) We now determine and display the time spent processing a

11173 *) mod_status: PID field of "dead" child slots no longer displays
11174 main httpd process's PID. [Jim Jagielski]
11176 *) Makefile.nt added - to build all the bits from the command line:
11177 nmake -f Makefile.nt
11178 Doesn't yet work properly. [Ben Laurie]
11180 *) Default text of 404 error is now "Not Found" rather than the
11181 potentially misleading "File Not Found". [Ken Coar]
11183 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
11184 for the net if we require people that actually need this data to
11185 enable it. [Linus Torvalds]
11187 *) directory_walk() is an expensive function, keep a little more state to
11188 avoid needless string counting. Add two new functions make_dirstr_parent
11189 and make_dirstr_prefix which replace all existing uses of make_dirstr.
11190 The new functions are a little less general than make_dirstr, but
11191 work more efficiently (less memory, less string counting).
11194 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
11195 to LDFLAGS) to avoid complications with lex rules in make files.
11196 [Dean Gaudet] PR#372
11198 *) run_method optimized to avoid needless scanning over NULLs in the
11199 module list. [Dean Gaudet]
11201 *) Revamp of (unix) scoreboard management code such that it avoids
11202 unnecessary traversals of the scoreboard on each hit. This is
11203 particularly important for high volume sites with a large
11204 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
11205 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
11206 httpd.h. [Dean Gaudet]
11208 *) In configurations using multiple Listen statements it was possible for
11209 busy sockets to starve other sockets of service. [Dean Gaudet]
11211 *) Added hook so standalone_main can be replaced at compile time
11212 (define STANDALONE_MAIN)
11215 *) Lowest-level read/write functions in buff.c will be replaced with
11216 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
11217 compile time. The default sfio discipline will behave as apache
11218 would without sfio compiled in.
11221 *) Enhance UserDir directive (mod_userdir) to accept a list of
11222 usernames for the 'disable' keyword, and add 'enable user...' to
11223 selectively *en*able userdirs if they're globally disabled.
11226 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
11227 will work with Netscape dbm files. (dbmmanage will probably not
11228 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
11230 *) Add a ListenBacklog directive to control the backlog parameter
11231 passed to listen(). Also change the default to 511 from 512.
11234 *) API: A new handler response DONE which informs apache that the
11235 request has been handled and it can finish off quickly, similar to
11236 how it handles errors. [Rob Hartill]
11238 *) Turn off chunked encoding after sending terminating chunk/footer
11239 so that we can't do it twice by accident. [Roy Fielding]
11241 *) mod_expire also issues Cache-Control: max-age headers.
11244 *) API: Added kill_only_once option for free_proc_chain so that it won't
11245 aggressively try to kill off specific children. For fastcgi.
11246 [Stanley Gambarin <gambarin OpenMarket.com>]
11248 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
11250 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
11251 When used together, these cause mod_dir to emit HEIGHT and WIDTH
11252 attributes in the FancyIndexing IMG tags. [Ken Coar]
11254 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
11256 *) PORT: Added Windows NT support
11257 [Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
11259 Changes with Apache 1.2.6
11261 *) mod_include when using XBitHack Full would send ETags in addition to
11262 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.

11355 possible buffer overflows and a possible infinite loop. This cleanup
11356 was done against 1.3 code and then backported to 1.2, the result
11357 is a large difference (due to indentation cleanup in 1.3 code).
11358 Users interested in seeing a smaller set of relevant differences

11426 Changes with Apache 1.2.2 [not released]
11428 *) Fixed another long-standing bug in sub_req_lookup_file where it would
11429 happily skip past access checks on subdirectories looked up with relative
11430 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
11433 *) Add lockfile name to error message printed out when
11434 USE_FLOCK_SERIALIZED_ACCEPT is defined.
11437 *) Enhanced the chunking and error handling inside the buffer functions.

11441 a vhost, put the main server's first and the vhost's second. Otherwise
11442 the vhost can't override the main server. [Dean Gaudet] PR#717
11444 *) The <Directory> code would merge and re-merge the same section after
11445 a match was found, possibly causing problems with some modules.

11449 [Dean Gaudet] PR#748
11451 *) mod_include cleanup showed that handle_else was being used to handle
11452 endif. It didn't cause problems, but it was cleaned up too.
11455 *) Last official synchronization of mod_rewrite with author version (because
11456 mod_rewrite is now directly developed by the author at the Apache Group):
11457 o added diff between mod_rewrite 3.0.6+ and 3.0.9

11500 [Dean Gaudet] PR#832
11502 *) API: In HTTP/1.1, whether or not a request message contains a body
11503 is independent of the request method and based solely on the presence
11504 of a Content-Length or Transfer-Encoding. Therefore, our default
11505 handlers need to be prepared to read a body even if they don't know
11506 what to do with it; otherwise, the body would be mistaken for the
11507 next request on a persistent connection. discard_request_body()
11508 has been added to take care of that. [Roy Fielding] PR#378

11511 release version number, such that it always increases along the
11512 same lines as our source code branching. [Roy Fielding]

11528 (headers, readmes, titles), mod_negotiation (type maps), or
11529 mod_cern_meta (meta files). [Dean Gaudet]
11531 *) SECURITY: Apache will refuse to run as "User root" unless
11532 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
11534 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
11535 if it contained a .htaccess disallowing symlinks. This is contrary
11536 to the rule that symlink permissions are tested with the symlink
11537 options of the parent directory. [Dean Gaudet] PR#353

11558 handle high numbered descriptors (examples include bind, and
11559 solaris libc). On all systems apache attempts to keep all permanent
11560 descriptors above 15 (called the low slack line). Solaris users
11561 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
11562 which keeps all non-FILE * descriptors above 255. On all systems
11563 this should make supporting large numbers of vhosts with many open
11564 log files more feasible. If this causes trouble please report it,
11565 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
11566 [Dean Gaudet] various PRs
11568 *) Related to the last entry, network sockets are now opened before
11569 log files are opened. The only known case where this can cause
11570 problems is under Solaris with many virtualhosts and many Listen
11571 directives. But using -DHIGH_SLACK_LINE=256 described above will
11572 work around this problem. [Dean Gaudet]

11627 reading from one buffer and writing to another, at least until it has
11628 a custom timeout handler. [Roy Fielding and Petr Lampa]

11673 original request-line. [Roy Fielding]
11675 *) Test for error conditions before creating output header fields, since
11676 we don't want the error message to include those fields. Likewise,
11677 reset the content_language(s) and content_encoding of the response
11678 before generating or redirecting to an error message, since the new
11679 message will have its own Content-* definitions. [Dean Gaudet]

11682 and 304 responses) and err_headers_out (headers sent with all responses).
11683 Avoid the overhead of copying tables if err_headers_out is empty
11684 (the usual case). [Roy Fielding]
11686 *) Fixed a couple places where a check for the default Content-Type was
11687 not properly checking both the value configured by the DefaultType

11699 *) The method for determining PATH_INFO has been restored to the pre-1.2b
11700 (and NCSA httpd) definition wherein it was the extra path info beyond
11701 the CGI script filename. The environment variable FILEPATH_INFO has
11702 been removed, and instead we supply the original REQUEST_URI to any
11703 script that wants to be Apache-specific and needs the real URI path.
11704 This solves a problem with existing scripts that use extra path info
11705 in the ScriptAlias directive to pass options to the CGI script.
11708 *) The _default_ change in 1.2b10 will change the behaviour on configs
11709 that use multiple Listen statements for listening on multiple ports.
11710 But that change is necessary to make _default_ consistent with other
11711 forms of <VirtualHost>. It requires such configs to be modified
11712 to use <VirtualHost _default_:*>. The documentation has been
11713 updated. [Dean Gaudet] PR#530

11774 fix some misuse of the pool string allocation functions. Also fixes
11775 a general problem with parsing URL query info into args for CGI scripts.
11776 [Roy Fielding] PR#339, 367, 354, 453
11778 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
11780 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
11782 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
11783 AuthDBAuthoritative. [Marc Slemko] PR#420
11785 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
11787 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
11788 object that can't be PUT, or FOOBAR for some method FOOBAR that
11789 apache doesn't know about at all). Log 404s that occur in mod_include.
11790 [Paul Sutton, John Van Essen]
11792 *) If a soft timeout (or lingerout) occurs while trying to flush a
11793 buffer or write inside buff.c or fread'ing from a CGI's output,
11794 then the timeout would be ignored. [Roy Fielding] PR#373
11796 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
11797 parsing of headers. If the terminating empty-line CRLF occurs starting
11798 at the 256th or 257th byte of output, then Navigator will think a normal
11799 image is invalid. We are guessing that this is because their initial
11800 read of a new request uses a 256 byte buffer. We check the bytes written
11801 so far and, if we are about to tickle the bug, we instead insert a
11802 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
11804 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
11805 of an external redirection. [Roy Fielding and Paul Sutton]
11807 *) Configure would create a broken Makefile if the configuration file
11808 contained a commented-out Rule. [Roy Fielding]
11810 *) Promote per_dir_config and subprocess_env from the subrequest to the
11811 main request in mod_negotiation. In particular this fixes a bug
11812 where <Files> sections wouldn't properly apply to negotiated content.
11815 *) Fix a potential deadlock in mod_cgi script_err handling.
11816 [Ralf S. Engelschall]
11818 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
11819 [Mitchell Blank Jr]
11821 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
11822 .htaccess files because the RewriteBase was not replaced correctly.
11823 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
11824 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
11826 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
11827 1.x the settings are those of pre-1.2b8. For 2.x we include
11828 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
11829 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
11830 [Dean Gaudet] PR#336, PR#340
11832 *) Redirect did not preserve ?query_strings when present in the client's
11833 request. [Dean Gaudet]
11835 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
11837 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
11839 *) Add UnixWare compile/install instructions. [Chuck Murcko]
11841 *) Add mod_example (illustration of API techniques). [Ken Coar]
11843 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
11845 *) Improve handling of directories when filenames have spaces in them.
11848 *) For hosts with multiple IP addresses, try all additional addresses if
11849 necessary to get a connect. Fail only if hostent address list is
11850 exhausted. [Chuck Murcko]
11852 *) More signed/unsigned port fixes. [Dean Gaudet]
11854 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
11857 Changes with Apache 1.2b8
11859 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
11860 to it. [Marc Slemko]
11862 *) The addition of <Location> and <File> directives made the
11863 sub_req_lookup_simple() function bogus, so we now handle
11864 the special cases directly. [Dean Gaudet]
11866 *) We now try to log where the server is dumping core when a fatal
11867 signal is received. [Ken Coar]
11869 *) Improved lingering_close by adding a special timeout, removing the
11870 spurious log messages, removing the nonblocking settings (they
11871 are not needed with the better timeout), and adding commentary
11872 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
11873 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
11875 *) Send error messages about setsockopt failures to the server error
11876 log instead of stderr. [Roy Fielding]
11878 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
11880 *) Stopgap solution for CGI 3-second delay with server-side includes: if
11881 processing a subrequest, allocate memory from r->main->pool instead
11882 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
11883 in the middle of an SSI request. [Dean Gaudet] PR #122
11885 *) Fixed status of response when POST is received for a nonexistent URL
11886 (was sending 405, now 404) and when any method is sent with a
11887 full-URI that doesn't match the server and the server is not acting
11888 as a proxy (was sending 501, now 403). [Roy Fielding]
11890 *) Host port changed to unsigned short. [Ken Coar] PR #276
11892 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
11894 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
11896 *) Report extra info from errno with many errors that cause httpd to exit.
11897 spawn_child, popenf, and pclosef now have valid errno returns in the
11898 event of an error. Correct problems where errno was stomped on
11899 before being reported. [Dean Gaudet]
11901 *) In the proxy, if the cache filesystem was full, garbage_coll() was
11902 never called, and thus the filesystem would remain full indefinitely.
11903 We now also remove incomplete cache files left if the origin server
11904 didn't send a Content-Length header and either the client has aborted
11905 transfer or bwrite() to client has failed. [Petr Lampa]
11907 *) Fixed the handling of module and script-added header fields.
11908 Improved the interface for sending header fields and reduced
11909 the duplication of code between sending okay responses and errors.
11910 We now always send both headers_out and err_headers_out, and
11911 ensure that the server-reserved fields are not being overridden,
11912 while not overriding those that are not reserved. [Roy Fielding]
11914 *) Moved transparent content negotiation fields to err_headers_out
11915 to reflect above changes. [Petr Lampa]
11917 *) Fixed the determination of whether or not we should make the
11918 connection persistent for all of the cases where some other part
11919 of the server has already indicated that we should not. Also
11920 improved the ordering of the test so that chunked encoding will
11921 be set whenever it is desired instead of only when KeepAlive
11922 is enabled. Added persistent connection capability for most error
11923 responses (those that do not indicate a bad input stream) when
11924 accessed by an HTTP/1.1 client. [Roy Fielding]
11926 *) Added missing timeouts for sending header fields, error responses,
11927 and the last chunk of chunked encoding, each of which could have
11928 resulted in a process being stuck in write forever. Using soft_timeout
11929 requires that the sender check for an aborted connection rather than
11930 continuing after an EINTR. Timeouts that used to be initiated before
11931 send_http_header (and never killed) are now initiated only within or
11932 around the routines that actually do the sending, and not allowed to
11933 propagate above the caller. [Roy Fielding]
11935 *) mod_auth_anon required an @ or a . in the email address, not both.
11938 *) per_dir_defaults weren't set correctly until directory_walk for
11939 name-based vhosts. This fixes an obscure bug with the wrong config
11940 info being used for vhosts that share the same ip as the server.
11943 *) Improved generation of modules/Makefile to be more generic for
11944 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
11946 *) Generate makefile dependency for Configuration based on the actual
11947 name given when running the Configure process. [Dean Gaudet]
11949 *) Fixed problem with vhost error log not being set prior to
11950 initializing virtual hosts. [Dean Gaudet]
11952 *) Fixed infinite loop when a trailing slash is included after a type map
11953 file URL (extra path info). [Petr Lampa]
11955 *) Fixed server status updating of per-connection counters. [Roy Fielding]
11957 *) Add documentation for DNS issues (reliability and security), and try
11958 to explain the virtual host matching process. [Dean Gaudet]
11960 *) Try to continue gracefully by disabling the vhost if a DNS lookup
11961 fails while parsing the configuration file. [Dean Gaudet]
11963 *) Improved calls to setsockopt. [Roy Fielding]
11965 *) Negotiation changes: Don't output empty content-type in variant list;
11966 Output charset in variant list; Return sooner from handle_multi() if
11967 no variants found; Add handling of '*' wildcard in Accept-Charset.
11968 [Petr Lampa and Paul Sutton]
11970 *) Fixed overlaying of request/sub-request notes and headers in
11971 mod_negotiation. [Dean Gaudet]
11973 *) If two variants' charset quality are equal and one is the default
11974 charset (iso-8859-1), then prefer the variant that was specifically
11975 listed in Accept-Charset instead of the default. [Petr Lampa]
11977 *) Memory allocation problem in push_array() -- it would corrupt memory
11978 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
11980 *) invoke_handler() doesn't handle mime arguments in content-type
11981 [Petr Lampa] PR#160
11983 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
11986 *) Fixed problem with ErrorDocument not working for virtual hosts
11987 due to one of the performance changes in 1.2b7. [Dean Gaudet]
11989 *) Log an error message if we get a request header that is too long,
11990 since it may indicate a buffer overflow attack. [Marc Slemko]
11992 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
11993 not reject URLs without a double-slash, as per RFC2068 section 3.2.
11994 [Ken Coar] PR #146, #187
11996 *) Added table entry placeholder for new header_parser callback
11997 in all of the distributed modules. [Ken Coar] PR #191
11999 *) Allow for cgi files without the .EXE extension on them under OS/2.
12000 [Garey Smiley] PR #59
12002 *) Fixed error message when resource is not found and URL contains
12003 path info. [Petr Lampa and Dean Gaudet] PR #40
12005 *) Fixed user and server confusion over what should be a virtual host
12006 and what is the main server, resulting in access to something
12007 other than the name defined in the virtualhost directive (but
12008 with the same IP address) failing. [Dean Gaudet]
12010 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
12011 AIX; improves the redirection stuff to enable the users to generally
12012 redirect to http, https, gopher and ftp; added TIME variable for
12013 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
12014 special patterns >STRING, <STRING and =STRING to RewriteCond, which
12015 can be used in conjunction with %{TIME} or other variables to create
12016 time-dependent rewriting rules. [Ralf S. Engelschall]
12018 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
12019 Module authors may need to adjust their code for proper cleanup to take
12020 place (that is, call note_cleanups_for_fd()). This change fixes problems
12021 with file descriptors being erroneously closed when the proxy module was
12022 in use. [Ben Laurie]
12024 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
12025 initgroups() to hose the group information needed for later
12026 comparisons. [Randy Terbush]
12028 *) Remove unnecessary call to va_end() in create_argv() which
12029 caused a SEGV on some systems.
12031 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
12034 *) Clear memory allocated for listeners. [Randy Terbush]
12036 *) Improved handling of IP address as a virtualhost address and
12037 introduced "_default_" as a synonym for the default vhost config.
12038 [Dean Gaudet] PR #212
12040 Changes with Apache 1.2b7
12042 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
12044 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
12046 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
12047 - replace protocol response numbers with symbols
12048 - save variant-list into main request notes
12049 - free allocated memory from subrequests
12050 - merge notes, headers_out and err_headers_out
12052 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
12053 "HTTP/#.# ###*" to be more lenient about what we accept.
12056 *) more proxy FTP bug fixes:
12057 - Changed send_dir() to remove user/passwd from displayed URL.
12058 - Changed login error messages to be more descriptive.
12059 - remove setting of SO_DEBUG socket option
12060 - Make ftp_getrc() more lenient about multiline responses,
12061 specifically, 230 responses which don't have continuation 230-
12062 on each line). These seem to be all NT FTP servers, and while
12063 perhaps questionable, they appear to be legal by RFC 959.
12064 - Add missing kill_timeout() after transfer to user completes.
12067 *) Fixed problem where a busy server could hang when restarting
12068 after being sent a SIGHUP due to child processes not exiting.
12071 *) Modify mod_include escaping so a '\' only signifies an escaped
12072 character if the next character is one that needs
12073 escaping. [Ben Laurie]
12075 *) Eliminated possible infinite loop in mod_imap when relative URLs are
12076 used with a 'base' directive that does not have a '/' in it.
12077 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
12079 *) Reduced the default timeout from 1200 seconds to 300, and the
12080 one in the sample configfile from 400 to 300. [Marc Slemko]
12082 *) Stop vbprintf from crashing if given a NULL string pointer;
12083 print (null) instead. [Ken Coar]
12085 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
12086 [Marc Slemko and Roy Fielding]
12088 *) Fixed problem with mod_cgi-generated internal redirects trying to
12089 read the request message-body twice. [Archie Cobbs and Roy Fielding]
12091 *) Reduced timeout on lingering close, removed possibility of a blocked
12092 read causing the child to hang, and stopped logging of errors if
12093 the socket is not connected (reset by client). [Roy Fielding]
12095 *) Rearranged main child loop to remove duplication of code in
12096 select/accept and keep-alive requests, fixed several bugs regarding
12097 checking scoreboard_image for exit indication and failure to
12098 account for all success conditions and trap all error conditions,
12099 prevented multiple flushes before closing the socket; close the entire
12100 socket buffer instead of just one descriptor, prevent logging of
12101 EPROTO and ECONNABORTED on platforms where supported, and generally
12102 improved readability. [Roy Fielding]
12104 *) Extensive performance improvements. Cleaned up inefficient use of
12105 auto initializers, multiple is_matchexp calls on a static string,
12106 and excessive merging of response_code_strings. [Dean Gaudet]
12108 *) Added double-buffering to mod_include to improve performance on
12109 server-side includes. [Marc Slemko]
12111 *) Several fixes for suexec wrapper. [Randy Terbush]
12112 - Make wrapper work for files on NFS filesystem.
12113 - Fix portability problem of MAXPATHLEN.
12114 - Fix array overrun problem in clean_env().
12115 - Fix allocation of PATH environment variable
12117 *) Removed extraneous blank line is description of mod_status chars.
12120 *) Logging of errors from the call_exec routine simply went nowhere,
12121 since the logfile fd has been closed, so now we send them to stderr.
12122 [Harald T. Alvestrand]
12124 *) Fixed core dump when DocumentRoot is a CGI.
12125 [Ben Laurie, reported by <geddis tesserae.com>]
12127 *) Fixed potential file descriptor leak in mod_asis; updated it and
12128 http_core to use pfopen/pfclose instead of fopen/fclose.
12129 [Randy Terbush and Roy Fielding]
12131 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
12132 as the DEC Alpha which is 64-bit but uses 32-bit ints.
12133 [Dean Gaudet and Ken Coar]
12135 *) Return a 302 response code to the client when sending a redirect
12136 due to a missing trailing '/' on a directory instead of a 301; now
12137 it is cacheable. [Markus Gyger]
12139 *) Fix condition where, if a bad directive occurs in .htaccess, and
12140 sub_request() goes first to this directory, then log_reason() will
12141 SIGSEGV because it doesn't have initialized r->per_dir_config.
12142 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
12144 *) Fix handling of lang_index in is_variant_better(). This was
12145 causing problems which resulted in the server sending the
12146 wrong language document in some cases. [Petr Lampa]
12148 *) Remove free() from clean_env() in suexec wrapper. This was nuking
12149 the clean environment on some systems.
12151 *) Tweak byteserving code (e.g. serving PDF files) to work around
12152 bugs in Netscape Navigator and Microsoft Internet Explorer.
12153 Emit Content-Length header when sending multipart/byteranges.
12156 *) Port to HI-UX/WE2. [Nick Maclaren]
12158 *) Port to HP MPE operating system for HP 3000 machines
12159 [Mark Bixby <markb cccd.edu>]
12161 *) Fixed bug which caused a segmentation fault if only one argument
12162 given to RLimit* directives. [Ed Korthof]
12164 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
12166 *) Improved buffered output to the client by delaying the flush decision
12167 until the BUFF code is actually about to read the next request.
12168 This fixes a problem introduced in 1.2b5 with clients that send
12169 an extra CRLF after a POST request. Also improved chunked output
12170 performance by combining writes using writev() and removing as
12171 many bflush() calls as possible. NOTE: Platforms without writev()
12172 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
12173 or Configure, unless we have already done so. [Dean Gaudet]
12175 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
12177 *) Fixed mod_info output corruption bug introduced by buffer overflow
12178 fixes. [Dean Gaudet]
12180 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
12181 for the special case of a 304 response. [Paul Sutton]
12183 *) Improved handling of TRACE method by bypassing normal method handling
12184 and header parsing routines; fixed Allow response to always allow TRACE.
12187 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
12189 *) Cleaned-up some of the generated HTML. [Ken Coar]
12191 Changes with Apache 1.2b6
12193 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
12195 *) Fix typo introduced in fix for potential infinite loop around
12196 accept() in child_main(). This change caused the rev to 1.2b6.
12197 1.2b5 was never a public beta.
12199 Changes with Apache 1.2b5
12201 *) Change KeepAlive semantics (On|Off instead of a number), add
12202 MaxKeepAliveRequests directive. [Alexei Kosut]
12204 *) Various NeXT compilation patches, as well as a change in
12205 regex/regcomp.c since that file also used a NEXT define.
12208 *) Allow * to terminate the end of a directory match in mod_dir.
12209 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
12211 *) Don't call can_exec() if suexec_enabled. Calling this requires
12212 scripts executed by the suexec wrapper to be world executable, which
12213 defeats one of the advantages of running the wrapper. [Randy Terbush]
12215 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
12218 *) Migration from sprintf() to snprintf() to avoid buffer
12219 overflows. [Marc Slemko]
12221 *) Provide portable snprintf() implementation (ap_snprintf)
12222 as well as *cvt family. [Jim Jagielski]
12224 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
12227 *) Remove mod_fastcgi.c from the distribution. This module appears
12228 to be maintained more through the Open Market channels and should
12229 continue to be easily available at http://www.fastcgi.com/
12231 *) Fixed bug in modules/Makefile that wouldn't allow building in more
12232 than one subdirectory (or cleaning, either). [Jeremy Laidman]
12234 *) mod_info assumed that the config files were relative to ServerRoot.
12237 *) CGI scripts called as an error document resulting from failed
12238 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
12240 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
12243 *) Properly check errno to prevent display of a directory index
12244 when server receives a long enough URL to confuse stat().
12247 *) Several security enhancements to suexec wrapper. It is _highly_
12248 recommended that previously installed versions of the wrapper
12249 be replaced with this version. [Randy Terbush, Jason Dour]
12251 - ~user execution now properly restricted to ~user's home
12252 directory and below.
12253 - execution restricted to UID/GID > 100
12254 - restrict passed environment to known variables
12255 - call setgid() before initgroups() (portability fix)
12256 - remove use of setenv() (portability fix)
12258 *) Add HTTP/1.0 response forcing. [Ben Laurie]
12260 *) Add access control via environment variables. [Ben Laurie]
12262 *) Add rflush() function. [Alexei Kosut]
12264 *) remove duplicate pcalloc() call in new_connection().
12266 *) Fix incorrect comparison which could allow number of children =
12267 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
12268 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
12270 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
12271 AIX PS/2, CONVEXOS. [Jim Jagielski]
12273 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
12274 It's more portable. [Martin Kraemer]
12276 *) Replace references to make in Makefile.tmpl with $(MAKE).
12279 *) Add ProxyBlock directive w/IP address caching. Add IP address
12280 caching to NoCache directive as well. ProxyBlock works with all
12281 handlers; NoCache now also works with FTP for anonymous logins.
12282 Still more code cleanup. [Chuck Murcko]
12284 *) Add "header parse" API hook [Ben Laurie]
12286 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
12288 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
12290 *) Correctly allow access and auth directives in <Files> sections in
12291 server config files. [Alexei Kosut]
12293 *) Fix bug with ServerPath that could cause certain files to be not
12294 found by the server. [Alexei Kosut]
12296 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
12297 double-quote from text and so that it properly checks for unsupported
12298 status codes using the new index_of_response interface. [Roy Fielding]
12300 *) Multiple fixes to the lingering_close code in order to avoid being
12301 interrupted by a stray timeout, to avoid lingering on a connection
12302 that has already been aborted or never really existed, to ensure that
12303 we stop lingering as soon as any error condition is received, and to
12304 prevent being stuck indefinitely if the read blocks. Also improves
12305 reporting of error conditions. [Marc Slemko and Roy Fielding]
12307 *) Fixed initialization of parameter structure for sigaction.
12308 [<mgyger itr.ch>, Adrian Filipi-Martin]
12310 *) Fixed reinitializing the parameters before each call to accept and
12311 select, and removed potential for infinite loop in accept.
12312 [Roy Fielding, after useful PR from <adrian virginia.edu>]
12314 *) Fixed condition where, if a child fails to fork, the scoreboard would
12315 continue to say SERVER_STARTING forever. Eventually, the main process
12316 would refuse to start new children because count_idle_servers() will
12317 count those SERVER_STARTING entries and will always report that there
12318 are enough idle servers. [Phillip Vandry]
12320 *) Fixed bug in bcwrite regarding failure to account for partial writes.
12321 Avoided calling bflush() when the client is pipelining requests.
12322 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
12324 *) Added description of "." mode in server-status [Jim Jagielski]
12326 Changes with Apache 1.2b4
12328 *) Fix possible race condition in accept_mutex_init() that
12329 could leave a small security hole open allowing files to be
12330 overwritten in cases where the server UID has write permissions.
12333 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
12335 *) Fix portablity problem in util_script where ARG_MAX may not be
12336 defined for some systems.
12338 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
12341 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
12342 style magic #! token for better script portability. [Garey Smiley]
12344 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
12345 execution for ~userdir CGI. [Jason Dour]
12347 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
12349 *) Fix month off by one in suexec wrapper logging.
12351 Changes with Apache 1.2b3:
12353 *) Fix error in mod_cgi which could cause resources not to be properly
12354 freed, or worse. [Dean Gaudet]
12356 *) Fix find_string() NULL pointer dereference. [Howard Fear]
12358 *) Add set_flag_slot() at the request of Dirk and others.
12361 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
12363 *) Add changes to improve the error message given for invalid
12364 ServerName parameters. [Dirk vanGulik]
12366 *) Add "Authoritative" directive for Auth modules that don't
12367 currently have it. This gives admin control to assign authoritative
12368 control to an authentication scheme and allow "fall through" for
12369 those authentication modules that aren't "Authoritative" thereby
12370 allowing multiple authentication mechanisms to be chained.
12373 *) Remove requirement for ResourceConfig/AccessConfig if not using
12374 the three config file layout. [Randy Terbush]
12376 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
12378 *) Changes to suexec wrapper to fix the following problems:
12379 1. symlinked homedirs will kill ~userdirs.
12380 2. initgroups() on Linux 2.0.x clobbers gr->grid.
12381 3. CGI command lines paramters problems
12382 4. pw-pwdir for "docroot check" still the httpd user's pw record.
12383 [Randy Terbush, Jason Dour]
12385 *) Change create_argv() to accept variable arguments. This fixes
12386 a problem where arguments were not getting passed to the CGI via
12387 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
12389 *) Collapse multiple slashes in path URLs to properly apply
12390 handlers defined by <Location>. [Alexei Kosut]
12392 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
12394 *) Improve the accuracy of request duration timings by setting
12395 r->request_time in read_request_line() instead of read_request().
12398 *) Reset timeout while reading via get_client_block() in mod_cgi.c
12399 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
12401 *) Add the ability to pass different Makefile.tmpl files to Configure
12402 using the -make flag. [Rob Hartill]
12404 *) Fix coredump triggered when sending a SIGHUP to the server caused
12405 by an assertion failure, in turn caused by an uninitialised field in a
12409 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
12410 PATH_INFO from previous versions of Apache (in certain situations,
12411 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
12412 [later removed in 1.2b11]
12414 *) Add rwrite() function to API to allow for sending strings of
12415 arbitrary length. [Doug MacEachern]
12417 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
12419 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
12420 NeXT. [Jim Jagielski]
12422 *) Removed recent modification to promote the status code on internal
12423 redirects, since the correct fix was to change the default log format
12424 in mod_log_config so that it outputs the original status. [Rob Hartill]
12426 Changes with Apache 1.2b2:
12428 *) Update set_signals() to use sigaction() for setting handlers.
12429 This appears to fix a re-entrant problem in the seg_fault()
12430 bus_error() handlers. [Randy Terbush]
12432 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
12434 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
12436 *) proxy_http.c bugfixes: [Chuck Murcko]
12437 1) fixes possible NULL pointer reference w/NoCache
12438 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
12439 host would cache nothing if it was in the local domain,
12440 and the local domain was in the NoCache list)
12441 3) Adds Host: header when not available
12442 4) Some code cleanup and clarification
12444 *) mod_include.c bugfixes:
12445 1) Fixed an ommission that caused include variables to not
12446 be parsed in config errmsg directives [Howard Fear]
12447 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
12448 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
12449 4) Allow backslash-escaping to all quoted text
12450 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
12451 5) Pass variable to command line if not set in XSSI's env
12454 *) Fix infinite loop when processing Content-language lines in
12455 type-map files. [Alexei Kosut]
12457 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
12459 *) Fixed problem in set_[user|group] that prevented CGI execution
12460 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
12462 *) Added PORTING information file. [Jim Jagielski]
12464 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
12466 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
12468 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
12469 USE_FCNTL_SERIALIZED_ACCEPT was intended.
12471 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
12472 which caused problems of systems where socket s_addr is >32bits.
12474 *) Added comment to explain (r->chunked = 1) side-effect in
12475 http_protocol.c [Roy Fielding]
12477 *) Replaced use of index() in mod_expires.c with more appropriate
12478 and portable isdigit() test. [Ben Laurie]
12480 *) Updated Configure for ...
12481 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
12482 *-dg-dgux* (bad pattern match)
12483 QNX (DEF_WANTHSREGEX=yes)
12484 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
12486 *-unixware211 (new)
12487 and added some user diagnostic info. [Ben Laurie]
12489 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
12490 for better portability. [Jim Jagielski]
12492 *) Updated helpers/GuessOS for ...
12493 SCO 5 (recognize minor releases)
12494 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
12495 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
12496 IRIX64 (-sgi-irix64)
12497 ULTRIX (-unknown-ultrix)
12498 SINIX (-whatever-sysv4)
12499 NCR Unix (-ncr-sysv4)
12500 and fixed something in helpers/PrintPath [Ben Laurie]
12502 Changes with Apache 1.2b1
12504 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
12506 Changes with Apache 1.1.1
12508 *) Fixed bug where Cookie module would make two entries in the
12509 logfile for each access [Mark Cox]
12511 *) Fixed bug where Redirect in .htaccess files would cause memory
12512 leak. [Nathan Neulinger]
12514 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
12516 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
12518 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
12520 Changes with Apache 1.1.0
12522 *) Bring NeXT support up to date. [Takaaki Matsumoto]
12524 *) Bring QNX support up to date. [Ben Laurie]
12526 *) Make virtual hosts default to main server keepalive parameters.
12527 [Alexei Kosut, Ben Laurie]
12529 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
12531 *) Fix missing address family for connect, also remove unreachable statement
12532 in mod_proxy. [Ben Laurie]
12534 *) mod_env now turned on by default in Configuration.tmpl.
12536 *) Bugs which were fixed:
12537 a) yet more mod_proxy bugs [Ben Laurie]
12538 b) CGI works again with inetd [Alexei Kosut]
12539 c) Leading colons were stripped from passwords [<osm interguide.com>]
12540 d) Another fix to multi-method Limit problem [<jk tools.de>]
12542 Changes with Apache 1.1b4
12544 *) r->bytes_sent variable restored. [Robert Thau]
12546 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
12548 *) More possibly unsecure programs removed from the support directory.
12550 *) More mod_auth_msql authentication improvements.
12552 *) VirtualHosts based on Host: headers no longer conflict with the
12555 *) OS/2 compatibility enhancements. [Gary Smiley]
12557 *) POST now allowed to directory index CGI scripts.
12559 *) Actions now work with files of the default type.
12561 *) Bugs which were fixed:
12562 a) more mod_proxy bugs
12563 b) early termination of inetd requests
12564 c) compile warnings on several systems
12565 d) problems when scripts stop reading output early
12567 Changes with Apache 1.1b3
12569 *) Much of cgi-bin and all of cgi-src has been removed, due to
12570 various security holes found and that we could no longer support
12573 *) The "Set-Cookie" header is now special-cased to not merge multiple
12574 instances, since certain popular browsers can not handle multiple
12575 Set-Cookie instructions in a single header. [Paul Sutton]
12577 *) rprintf() added to buffer code, occurrences of sprintf removed.
12580 *) CONNECT method for proxy module, which means tunneling SSL should work.
12581 (No crypto needed) Also a NoCache config directive.
12583 *) Several API additions: pstrndup(), table_unset() and get_token()
12584 functions now available to modules.
12586 *) mod_imap fixups, in particular Location: headers are now complete
12589 *) New "info" module which reports on installed module set through a
12590 special URL, a la mod_status.
12592 *) "ServerPath" directive added - allows for graceful transition
12593 for Host:-header-based virtual hosts.
12595 *) Anonymous authentication module improvements.

12599 *) Status module design improved - output now table-based. [Ben Laurie]
12601 *) htdigest utility included for use with digest authentication
12604 *) mod_negotiation: Accept values with wildcards to be treated with
12605 less priority than those without wildcards at the same quality
12606 value. [Alexei Kosut]
12608 *) Bugs which were fixed:
12609 a) numerous mod_proxy bugs
12610 b) CGI early-termination bug [Ben Laurie]
12611 c) Keepalives not working with virtual hosts
12612 d) RefererIgnore problems
12613 e) closing fd's twice in mod_include (causing core dumps on
12614 Linux and elsewhere).
12616 Changes with Apache 1.1b2
12619 a) core dumps in mod_digest
12620 b) truncated hostnames/ip address in the logs
12621 c) relative URL's in mod_imap map files
12623 Changes with Apache 1.1b1
12625 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12627 Changes with Apache 1.0.3
12629 *) Internal redirects which occur in mod_dir.c now preserve the
12630 query portion of a request (the bit after the question mark).
12633 *) Escape active characters '<', '>' and '&' in html output in
12634 directory listings, error messages and redirection links.
12637 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12639 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12642 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12644 *) Reset timeout timer after each successful fwrite() to the network.
12645 This patch adds a reset_timeout() procedure that is called by
12646 send_fd() to reset the timeout ever time data is written to the net.
12649 *) timeout() signal handler now checks for SIGPIPE and reports
12650 lost connections in a more user friendly way. [Rob Hartill]
12652 *) Location of the "scoreboard" file which used to live in /tmp is
12653 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12654 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12656 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12658 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12659 which caused a SEGV with cookies enabled
12661 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12664 *) Log the UNIX textual error returned by some system calls, in
12665 particular errors from accept() [David Robinson]
12667 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12669 Changes with Apache 1.0.2
12671 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12672 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12674 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12677 *) past changes to http_config.c to only use the
12678 setrlimit function on systems defining RLIMIT_NOFILE
12679 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12680 for SUNOS and prototypes the needed functions.
12682 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12685 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12687 *) Merge multiple headers from CGI scripts instead of taking last
12688 one. [David Robinson]
12690 *) Add support for SCO 5. [Ben Laurie]
12692 Changes with Apache 1.0.1
12694 *) Silence mod_log_referer and mod_log_agent if not configured
12697 *) Recursive includes can occur if the client supplies PATH_INFO data
12698 and the server provider uses relative links; as file.html
12699 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
12701 *) The replacement for initgroups() did not call {set,end}grent(). This
12702 had two implications: if anything else used getgrent(), then
12703 initgroups() would fail, and it was consuming a file descriptor.
12706 *) On heavily loaded servers it was possible for the scoreboard to get
12707 out of sync with reality, as a result of a race condition.
12708 The observed symptoms are far more Apaches running than should
12709 be, and heavy system loads, generally followed by catastrophic
12710 system failure. [Ben Laurie]
12712 *) Fix typo in license. [David Robinson]
12714 Changes with Apache 1.0.0 23 Nov 1995
12716 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
12718 Changes with Apache 0.8.16 05 Nov 1995
12720 *) New man page for 'httpd' added to support directory [David Robinson]
12722 *) .htgroup files can have more than one line giving members for a
12723 given group (each must have the group name in front), for NCSA
12724 back-compatibility [Robert Thau]
12726 *) Mutual exclusion around accept() is on by default for SVR4 systems
12727 generally, since they generally can't handle multiple processes in
12728 accept() on the same socket. This should cure flaky behavior on
12729 a lot of those systems. [David Robinson]
12731 *) AddType, AddEncoding, and AddLanguage directives take multiple
12732 extensions on a single command line [David Robinson]
12734 *) UserDir can be disabled for a given virtual host by saying
12735 "UserDir disabled" in the <VirtualHost> section --- it was a bug
12736 that this didn't work. [David Robinson]
12738 *) Compiles on QNX [Ben Laurie]
12740 *) Corrected parsing of ctime time format [David Robinson]
12742 *) httpd does a perror() before exiting if it can't log its pid
12743 to the PidFile, to make diagnosing the error a bit easier.
12746 *) <!--#include file="..."--> can no longer include files in the
12747 parent directory, for NCSA back-compatibility. [David Robinson]
12749 *) '~' is *not* escaped in URIs generated for directory listings
12752 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
12754 *) Fixed bug involving handling URIs with escaped %-characters
12755 in redirects [David Robinson]
12757 Changes with Apache 0.8.15 14 Oct 1995
12759 *) Switched to new, simpler license
12761 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
12763 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
12765 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
12767 *) Correctly handles internal redirects to files with names containing '%'
12770 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
12772 *) Use geteuid() rather than getuid() to see if we have root privilege,
12773 so that server correctly resets privilege if run setuid root. [Andrew
12776 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
12779 *) Fix relative URLs in imagemap files [Randy Terbush]
12781 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
12784 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
12785 entries all name the same one. [David Robinson]
12787 *) Fix directory listings with filenames containing unusual characters
12790 *) Better URI-escaping for generated URIs in directories with filenames
12791 containing unusual characters [Ben Laurie]
12793 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
12795 *) Unblock alarms on error return from spawn_child() [David Robinson]
12797 *) Sample Config files have extra note for SCO users [Ben Laurie]
12799 *) Configuration has note for HP-UX users [Rob Hartill]
12801 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
12803 *) Nuked bogus #define in httpd.h [David Robinson]
12805 *) Better test for whether a system has setrlimit() [David Robinson]
12807 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
12809 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
12812 Changes with Apache 0.8.14 19 Sep 1995
12814 *) Compiles on SCO ODT 3.0 [Ben Laurie]
12816 *) AddDescription works (better) [Ben Laurie]
12818 *) Leaves an intelligible error diagnostic when it can't set group
12819 privileges on standalone startup [Andrew Wilson]
12821 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
12822 that machine, which claims to be BSD but does not support RLIMIT.
12825 *) gcc -Wall no longer complains about an unused variable when util.c
12826 is compiled with -DMINIMAL_DNS [Andrew Wilson]
12828 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
12830 Changes with Apache 0.8.13 07 Sep 1995
12832 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
12834 *) Have built-in imagemap code recognize & honor Point directive [James
12837 *) Generate cleaner directory listings in directories with a mix of
12838 long and short filenames [Rob Hartill]
12840 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
12842 *) Properly default ServerName for virtual servers [Robert Thau]
12844 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
12845 Paul Richards and a cast of thousands...]
12847 *) On self-identified BSD systems (we don't try to guess any more),
12848 allocate a few extra file descriptors per virtual host with setrlimit,
12849 if we can, to avoid running out. [Randy Terbush]
12851 *) Write 22-character lock file name into buffer with enough space
12852 on startup [Konstantin Olchanski]
12854 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
12857 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
12859 *) Suppress -Wall warning by initializing variable in negotiation code
12860 [Tobias Weingartner]
12862 Changes with Apache 0.8.12 31 Aug 1995
12864 *) Doesn't pause three seconds after including a CGI script which is
12865 too slow to die off (this is done by not even trying to kill off
12866 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
12867 after the entire document has been processed). [Robert Thau]
12869 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
12871 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
12873 *) Allows .htaccess files to override <Directory> sections naming the
12874 same directory [David Robinson]
12876 *) Removed an efficiency hack in sub_req_lookup_uri which was
12877 causing certain extremely marginal cases (e.g., ScriptAlias of a
12878 *particular* index.html file) to fail. [David Robinson]
12880 *) Doesn't log an error when the requested URI requires
12881 authentication, but no auth header line was supplied by the
12882 client; this is a normal condition (the client doesn't no auth is
12883 needed here yet). [Robert Thau]
12885 *) Behaves more sanely when the name server loses its mind [Sean Welch]
12887 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
12889 *) RFC931 code no longer passes out name of prior clients on current
12890 requests if the current request came from a server that doesn't
12891 do RFC931. [David Robinson]
12893 *) Configuration script accepts "Module" lines with trailing whitespace.
12896 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
12898 *) Cleaned up comments in mod_cgi.c [Robert Thau]
12900 Changes with Apache 0.8.11 24 Aug 1995
12902 *) Wildcard <Directory> specifications work. [Robert Thau]
12904 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
12906 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
12907 the file being requested itself, in addition to the directories leading
12908 up to it. [Robert Thau]
12910 *) Logs access failures due to symlink checks or invalid client address
12911 in the error log [Roy Fielding, Robert Thau]
12913 *) Symlink checks deal correctly with systems where lstat of
12914 "/path/to/some/link/" follows the link. [Thau, Fielding]
12916 *) Doesn't reset DirectoryIndex to 'index.html' when
12917 other directory options are set in a .htaccess file. [Robert Thau]
12919 *) Clarified init code and nuked bogus warning in mod_access.c
12920 [Florent Guillaume]
12922 *) Corrected several directives in sample srm.conf
12923 --- includes corrections to directory indexing icon-related directives
12924 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
12925 icons for encodings right, and turning on AddEncoding by default).
12928 *) Corrected descriptions of args to AddIcon and AddAlt in command table
12931 *) INSTALL & README mention "contributed modules" directory [Brian
12934 *) Fixed English in the license language... "for for" --> "for".
12937 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
12938 mod_alias.c, merging it almost completely with handling of Alias, and
12939 adding a 'notes' field to the request_rec which allows the CGI module
12940 to discover whether the Alias module has put this request through
12941 ScriptAlias (which it needs to know for back-compatibility, as the old
12942 NCSA code did not check Options ExecCGI in ScriptAlias directories).
12945 Changes with Apache 0.8.10 18 Aug 1995
12947 *) AllowOverride applies to the named directory, and not just
12948 subdirectories. [David Robinson]
12950 *) Do locking for accept() exclusion (on systems that need it)
12951 using a special file created for the purpose in /usr/tmp, and
12952 not the error log; using the error log causes real problems
12953 if it's NFS-mounted; this is known to be the cause of a whole
12954 lot of "server hang" problems with Solaris. [David Robinson;
12955 thanks to Merten Schumann for help diagnosing the problem].
12957 Changes with Apache 0.8.9 12 Aug 1995
12959 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
12961 *) Nested includes see environment variables of the including document,
12962 for NCSA bug-compatibility (some sites have standard footer includes
12963 which try to print out the last-modified date). [Eric Hagberg/Robert
12966 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
12967 URI as a CGI script, even if it would have been treated as something
12968 else if requested directly, for NCSA back-compatibility. (Note that
12969 this means that people who know the name of the script can see the
12970 code just by asking for it). [Robert Thau]
12972 *) New version of dbmmanage script included in support directory as
12975 *) Check if scoreboard file couldn't be opened, and say so, rather
12976 then going insane [David Robinson]
12978 *) POST to CGI works on A/UX [Jim Jagielski]
12980 *) AddIcon and AddAlt commands work properly [Rob Hartill]
12982 *) NCSA server push works properly --- the Arena bug compatibility
12983 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
12984 if you still want the workaround). [Rob Hartill]
12986 *) If client didn't submit any Accept-encodings, ignore encodings in
12987 content negotiation. (NB this will all have to be reworked anyway
12988 for the new HTTP draft). [Florent Guillaume]
12990 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
12992 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
12994 *) Give Redirect priority over Alias, for NCSA bug compatibility
12997 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
12998 paralleling earlier bug fix for CGI [David Robinson]
13000 *) If DBM auth is improperly configured, report a server error and don't
13003 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
13004 it seems to work well enough without it (even in a 10 hits/sec
13005 workout), and the overhead for the locking under A/UX is
13006 alarmingly high (though it is very low on other systems).
13007 [Eric Hagberg, Jim Jagielski]
13009 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
13011 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
13012 Behlendorf/Eric Hagberg]
13014 *) More improvements to default Configuration for A/UX [Jim Jagielski]
13016 *) Compiles clean on NEXT [Rob Hartill]
13018 *) Compiles clean on SGI [Robert Thau]
13020 Changes with Apache 0.8.8 08 Aug 1995
13022 *) SunOS library prototypes now never included unless explicitly
13023 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
13024 people using GNU libc on SunOS are screwed by prototypes for the
13027 (Those who wish to compile clean with gcc -Wall on a standard
13028 SunOS setup need the prototypes, and may obtain them using
13029 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
13030 with nonstandard libraries are presumably competent to make their
13033 *) Strips trailing '/' characters off both args to the Alias command,
13034 to make 'Alias /foo/ /bar/' work.
13036 Changes with Apache 0.8.7 03 Aug 1995
13038 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
13039 [reported by David Robinson]
13041 *) Compiles clean on OSF/1 [David Robinson]
13043 *) Added some of the more recent significant changes (AddLanguage stuff,
13044 experimental LogFormat support) to CHANGES file in distribution root
13047 Changes with Apache 0.8.6 02 Aug 1995
13049 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
13050 (If you actually wanted a conditional GET which bypassed the cache, you
13051 couldn't get it). [Reported by Roy Fielding]
13053 *) Properly terminate headers on '304 Not Modified' replies to conditional
13054 GETs --- no browser we can find cares much, but the CERN proxy chokes.
13055 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
13057 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
13059 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
13060 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
13061 and older versions don't set the __SUNPRO_C preprocessor variable). On
13062 all other systems, these are never used anyway. [Reported by Mark Cox].
13064 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
13066 Changes with Apache 0.8.5 01 Aug 1995
13068 *) Added last-minute configurable log experiment, as optional module
13070 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
13071 properly. (One-line fix to http_protocol.c).
13073 *) Work around bogus behavior when reloading from Netscape.
13074 It's Netscape's bug --- for some reason they expect a request with
13075 If-modified-since: to not function as a conditional GET if it also
13076 comes with Pragma: no-cache, which is way out of line with the HTTP
13077 spec (according to Roy Fielding, the redactor).
13079 *) Added parameter to set maximum number of server processes.
13081 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
13084 *) IdentityCheck bugfix [Chuck Murcko].
13086 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
13088 *) More sample config file corrections; add extension to AddType for
13089 *.asis, move AddType generic description to its proper place, and
13090 fix miscellaneous typos. [ Alexei Kosut ]
13092 *) Deleted the *other* reference to the regents from the Berkeley
13093 legal disclaimer (everyplace).
13095 *) Nuked Shambhala name from src/README; had already cleaned it out
13096 of everywhere else.
13098 Changes with Apache 0.8.4
13100 *) Changes to server-pool management parms --- renamed current
13101 StartServers to MinSpareServers, created separate StartServers
13102 parameter which means what it says, and renamed MaxServers to
13103 MaxSpareServers (though the old name still works, for NCSA 1.4
13104 back-compatibility). The old names were generally regarded as
13105 too confusing. Also altered "docs" in sample config files.
13107 *) More improvements to default config files ---
13108 sample directives (commented out) for XBitHack, BindAddress,
13109 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
13110 defaults, AddTypes for send-as-is and imagemap magic types, and
13111 improvements to samples for DirectoryIndex [Alexei Kosut]
13113 *) Yet more improvements to default config files --- changes to
13114 Alexei's sample AddLanguage directives, and sample LanguagePriority
13115 [ Florent Guillaume ]
13117 *) Set config file locations properly if not set in httpd.conf
13120 *) Don't escape URIs in internal redirects multiple times; don't
13121 do that when translating PATH_INFO to PATH_TRANSLATED either.
13124 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
13126 Changes with Apache 0.8.3
13128 *) Edited distribution README to *briefly* summarize installation
13129 procedures, and give a pointer to the INSTALL file in the src/
13132 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
13133 recent NCSA distributions.
13135 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
13136 exist for the same directory, use both and don't segfault. [Reported
13139 *) Proper makefile dependencies [David Robinson]
13141 *) Note (re)starts in error log --- reported by Rob Hartill.
13143 *) Only call no2slash() after get_path_info() has been done, to
13144 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
13145 reported by Andrew Wilson, though this one is probably a real bug]
13147 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
13148 dump core when Referer is not supplied. [Randy Terbush]
13150 *) Lightly edited sample config files to refer people to our documentation
13151 instead of NCSA's, and to list Rob McCool as *original* author (also
13152 deleted his old, and no doubt non-functional email address). Would be
13153 nice to have examples of new features...
13155 Changes with Apache 0.8.2 19 Jul 1995
13157 *) Added AddLanuage code [Florent Guillaume]
13159 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
13161 *) All sorts of problems when MultiViews finds a directory. It would
13162 be nice if mod_dir.c was robust enough to handle that, but for now,
13163 just punt. [reported by Brian Behlendorf]
13165 *) Wait for all children on restart, to make sure that the old socket
13166 is gone and we can reopen it. [reported by Randy Terbush]
13168 *) Imagemap module is enabled in default Configuration
13170 *) RefererLog and UserAgentLog modules properly default the logfile
13173 *) Mark Cox's mod_cookies added to the distribution as an optional
13174 module (commented out in the default Configuration, and noted as
13175 an experiment, along with mod_dld). [Mark Cox]
13177 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
13179 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
13181 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
13183 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
13186 Changes with Apache 0.8.1
13188 *) New imagemap module [Randy Terbush]
13190 *) Replacement referer log module with NCSA-compatible RefererIgnore
13191 [Matthew Gray again]
13193 *) Don't mung directory listings with very long filenames.
13194 [Florent Guillaume]
13196 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
13198 *) New config script. See INSTALL for info. [Robert Thau]
13200 *) Scoreboard mechanism for regulating the number of extant server
13201 processes. MaxServers and StartServers defaults are the same as
13202 for NCSA, but the meanings are slightly different. (Actually,
13203 I should probably lower the MaxServers default to 10).
13205 Before asking for a new connection, each server process checks
13206 the number of other servers which are also waiting for a
13207 connection. If there are more than MaxServers, it quietly dies
13208 off. Conversely, every second, the root, or caretaker, process
13209 looks to see how many servers are waiting for a new connection;
13210 if there are fewer than StartServers, it starts a new one. This
13211 does not depend on the number of server processes already extant.
13212 The accounting is arranged through a "scoreboard" file, named
13213 /tmp/htstatus.*, on which each process has an independent file
13214 descriptor (they need to seek without interference).
13216 The end effect is that MaxServers is the maximum number of
13217 servers on an *inactive* server machine, but more will be forked
13218 off to handle unusually heavy loads (or unusually slow clients);
13219 these will die off when they are no longer needed --- without
13220 reverting to the overhead of full forking operation. There is a
13221 hard maximum of 150 server processes compiled in, largely to
13222 avoid forking out of control and dragging the machine down.
13223 (This is arguably too high).
13225 In my server endurance tests, this mechanism did not appear to
13226 impose any significant overhead, even after I forced it to put the
13227 scoreboard file on a normal filesystem (which might have more
13228 overhead than tmpfs). [Robert Thau]
13230 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
13233 *) Read .htaccess files even in directory with <Directory> section.
13234 (Former incompatibility noted on mailing list, now fixed). [Robert
13237 *) "HEAD /" gives the client a "Bad Request" error message, rather
13238 than trying to send no body *and* no headers. [Cliff Skolnick].
13240 *) Don't produce double error reports for some very obscure cases
13241 mainly involving auth configuration (the "all modules decline to
13242 handle" case which is a sure sign of a server bug in most cases,
13243 but also happens when authentication is badly misconfigured).
13246 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
13247 it's *for*, and this sort of thing really shouldn't be cluttering
13248 up the Makefile). [Robert Thau]
13250 *) Incidental code cleanups in http_main.c --- stop dragging
13251 sa_client around; just declare it where used. [Robert Thau]
13253 *) Another acc-related fix. (It doesn't like const char
13254 in some places...). [Mark Cox]
13256 Changes with Shambhala 0.6.1 13 Jul 1995
13258 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
13259 Also, fixed auth typo in http_protocol.c unmasked by this fix.
13261 *) Compiles clean with acc on SunOS [Paul Sutton]
13263 *) Reordered modules in modules.c so that Redirect takes priority
13264 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
13265 believe it or not, he has an actual site with a ScriptAlias and
13266 a Redirect declared for the *exact same directory*. Even *my*
13267 compatibility fetish wouldn't motivate me to fix this if the fix
13268 required any effort, but it doesn't, so what the hey.
13270 *) Fixed to properly default several server_rec fields for virtual
13271 servers from the corresponding fields in the main server_rec.
13272 [Cliff Skolnick --- 'port' was a particular irritant].
13274 *) No longer kills off nph- child processes before they are
13275 finished sending output. [Matthew Gray]
13277 Changes with Shambhala 0.6.0 10 Jul 1995
13279 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
13280 the connection to the client in an "aborted" state, but otherwise
13281 allow whatever handlers are running to clean up. hard_timeout()s
13282 abort the request in progress completely; anything not tied to some
13283 resource pool cleanup will leak. They're still around because I
13284 haven't yet come up with a more elegant way of handling
13285 timeouts when talking to something that isn't the client. The
13286 default_handler and the dir_handler now use soft timeouts, largely
13287 so I can test the feature. [Robert Thau]
13289 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
13290 the case of log handlers dying prematurely is probably handled VERY
13291 gracelessly at this point, and if the logger stops reading input,
13292 the server will hang. (It is known to correctly restart the
13293 logging process on server restart; this is (should be!) going through
13294 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
13295 script). [Robert Thau]
13297 *) asis files supported (new module). [Robert Thau]
13299 *) IdentityCheck code is compiled in, but has not been tested. (I
13300 don't know anyone who runs identd). [Robert Thau]
13302 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
13303 came in with the request, for NCSA bug-compatibility. [Robert Thau]
13305 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
13307 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
13308 as timeouts are not in scope. [Robert Thau]
13310 *) quoted-string args in config files now handled correctly (doesn't drop
13311 the last character). [Robert Thau; reported by Randy Terbush]
13313 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
13314 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
13316 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
13317 default default type); the former default default behavior when all
13318 type-checkers defaulted had been a core dump. [Paul Sutton]
13320 *) Copy filenames out of the struct dirent when indexing
13321 directories. (On Linux, readdir() returns a pointer to the same
13322 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
13324 Changes with Shambhala 0.5.3 [not released]
13326 *) Default response handler notes "file not found" in the error log,
13327 if the file was not found. [Cliff Skolnick].
13329 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
13330 code no longer sets up bogus PATH_INFO which fakes out the directory
13331 handler). [Cliff Skolnick]
13333 Changes with Shambhala 0.5.2 06 Jul 1995
13335 *) Changes to http_main.c --- root server no longer plays silly
13336 games with SIGCHLD, and so now detects and replaces dying
13337 children. Child processes just die on SIGTERM, without taking
13338 the whole process group with them. Potential problem --- if any
13339 child process refuses to die, we hang in restart.
13340 MaxRequestsPerChild may still not work, but it certainly works
13341 better than it did before this! [Robert Thau]
13343 *) mod_dir.c bug fixes: ReadmeName and HeaderName
13344 work (or work better, at least); over-long description lines
13345 properly terminated. [Mark Cox]
13347 *) http_request.c now calls unescape_url() more places where it
13348 should [Paul Sutton].
13350 *) More directory handling bugs (reported by Cox)
13351 Parent Directory link is now set correctly. [Robert Thau]
13353 Changes with Shambhala 0.5.1 04 Jul 1995
13355 *) Generalized cleanup interface in alloc.c --- any function can be
13356 registered with alloc.c as a cleanup for a resource pool;
13357 tracking of files and file descriptors has been reimplemented in
13358 terms of this interface, so I can give it some sort of a test.
13361 *) More changes in alloc.c --- new cleanup_for_exec() function,
13362 which tracks down and closes all file descriptors which have been
13363 registered with the alloc.c machinery before the server exec()s a
13364 child process for CGI or <!--#exec-->. CGI children now get
13365 started with exactly three file descriptors open. Hopefully,
13366 this cures the problem Rob H. was having with overly persistent
13367 CGI connections. [Robert Thau]
13369 *) Mutual exclusion around the accept() in child_main() --- this is
13370 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
13371 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
13372 This uses fcntl(F_SETLK,...) on the error log descriptor because
13373 flock() on that descriptor won't work on systems which have BSD
13374 flock() semantics, including (I think) Linux 1.3 and Solaris.
13376 This does work on SunOS (when the server is idle, only one
13377 process in the pool is waiting on accept()); it *ought* to work
13378 on the other systems. [Robert Thau]
13380 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
13382 *) sizeof(*sa_client) bugfix from [Rob Hartill]
13384 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
13386 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
13387 be unnecessary if I go to the revised timeout-handling scheme).
13390 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
13391 string) even if none came in with the request. [Robert Thau]
13393 *) CHANGES file added to distribution ;-).
13395 Changes with Shambhala 0.4.5
13397 *) mod_dld --- early dynamic loading support [rst]
13398 *) Add wildcard content handlers for XBITHACK; default_hander now
13399 invoked with that mechanism (as a handler hanging off mod_core) [rst]
13400 *) XBITHACK supported as a wildcard content-handler, and
13401 configurable at run-time (not just at compile time, as in the
13402 "patchy server" releases) [rst]
13404 Changes with Shambhala 0.4.4 30 Jun 1995
13406 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
13407 *) Handle Addtype x/y .z [rst, reported by Cox]
13409 Changes with Shambhala 0.4.3
13411 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
13412 synonymous [rst, terbush]
13414 Changes with Shambhala 0.4.1 28 Jun 1995
13416 *) First-cut virtual host implementation; some refit in the config
13417 reading code, and log management, was necessary to support this [rst]
13418 *) Sub-pool machinery, originally added to avoid excessive storage
13419 allocation on listings of large directories (which turned out to
13420 be the problem that the 0.3 storage accounting was added to
13421 find). Subrequests and mod_dir changed to use subpools. [rst]
13422 *) More memory debugging --- free list consistency checks. [rst]
13423 *) Added err_headers to request_rec, with support elsewhere [rst]
13424 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
13426 Changes with Shambhala 0.3 19 Jun 1995
13428 *) Switch ONE_PROCESS to a runtime command-line option (-X)
13429 *) Don't compile in mod_ai_backcompat by default
13430 *) Switch name of server from Apache to Shambhala in Makefile
13431 *) Add some accounting routines to track memory usage in the pools,
13434 Changes with Shambhala 0.2
13436 *) Set DOCUMENT_ROOT CGI variable
13437 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
13438 *) Add critical section protection to handling of cleanup structures
13440 *) Significant code reorg within the server core to group related
13441 functions together [rst]
13442 *) Correctly handle clients that hang up before sending any request
13444 *) Replace dying child processes. [rst]
13446 Changes with Shambhala 0.1 12 Jun 1995
13448 Major rewrite of the pre-existing "patchy server" codebase, by
13449 Robert Thau (rst). Significant portions of the server code, such
13450 as configuration-file handling and HTTP authentication support,
13451 were ripped out and rewritten from scratch. Code that was not
13452 completely rewritten was significantly altered.
13454 Major changes with this release include:
13456 *) Introduction of the module API; in request handling, the central
13457 machinery just dispatches to various modules, which actually do
13458 most of the work. Configuration handling is similar --- modules
13459 declare their own commands, and the central machinery just
13460 dispatches to them.
13462 API features from shambhala/0.1 were substantially unchanged in
13463 Apache 1.0 and 1.1. (1.0 API features not yet present in this
13464 release, such as wildcard handlers and subpools, were added in
13465 subsequent Shambhala releases, and were also generally rst's
13468 *) This release included the following modules:
13470 mod_access (access control --- allow and deny directives),
13471 mod_alias (Alias and Redirect commands),
13472 mod_auth (straight HTTP authentication, based on flat-files)
13473 mod_auth_dbm (same, with dbm files)
13474 mod_cgi (CGI scripts and, in this release, ScriptAlias)
13475 mod_common_log (CLF access logs; later renamed mod_log_common)
13476 mod_dir (directory indexing)
13477 mod_include (server-side includes)
13478 mod_mime (AddType directives)
13479 mod_negotiation (content negotiation)
13480 mod_userdir (support for users' public_html directories)
13482 It also included a mod_ai_backcompat, which was a private hack
13483 for back-compatibility with rst's own AI-lab servers.
13485 All of these modules were substantially complete, and functional
13486 or nearly so (a few, which implemented features not in use at
13487 Thau's site, required patches of a few lines).
13489 *) sub-request machinery, to allow modules to determine how other
13490 modules would assign MIME types to a given file, or optionally
13491 serve its content (this is heavily used by mod_dir, mod_include
13492 and mod_negotiation).
13494 *) Resource pool system for keeping track of memory allocated and
13495 files opened in service of a particular request. Much of the
13496 code in the modules (when they weren't rewrites) was adjusted to
13497 replace a pervasive convention of using fixed-size buffers on
13498 the stack with an equally pervasive convention of using memory
13499 allocated with palloc().
13501 *) Reorganization of data structures associated with a given
13502 request to eliminate use of global variables and the troublesome
13503 unmunge_name function (used in NCSA and early Apache releases to
13504 attempt to determine the URI which mapped to a given filename
13505 --- a difficult proposition, given that it is easy to produce
13506 setups in which multiple URIs map to the same file).
13508 *) Source files renamed and rearranged
13510 *) Very simple pre-forking behavior --- parent process forked off a
13511 fixed number of children, and then just waited for SIGHUP.
13513 *) Other more minor changes too numerous to list.
13515 This release included modified versions of a lot of code from the
13516 Apache 0.6.4 public release, plus an early pre-forking patch
13517 codeveloped by Robert Thau and Rob Hartill.
13519 Changes with Apache 0.7.3 20 Jun 1995
13521 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
13522 were incorporated by Rob Hartill on the main branch while Robert Thau
13523 worked on the Shambhala rewrite above. Most were merged into the
13524 Shambala architecture after Apache 0.8.0.
