1 Changes with Apache 2.1.0-dev
3 [Remove entries to the current 2.0 section below, when backported]
5 *) Fixed file extensions for real media files and removed rpm extension
6 from mime.types. PR 26079. [Allan Sandfeld <kde carewolf.com>]
8 *) worker MPM: fix stack overlay bug that could cause the parent
9 process to crash. [Jeff Trawick]
11 *) Unix MPMs: Stop dropping connections when the file descriptor
12 is at least FD_SETSIZE. [Jeff Trawick]
14 *) Add core version query function (ap_get_server_revision) and
15 accompanying ap_version_t structure (minor MMN bump).
18 *) mod_rewrite: EOLs sent by external rewritemaps are now consumed
19 as whole. That way, on systems with more than one EOL character
20 rewritemap programs no longer need to switch stdout to binary
21 mode. PR 25635. [André Malo]
23 *) mod_rewrite: Introduce the ability to force a content handler via
24 the [handler=...] flag. [André Malo]
26 *) mod_rewrite: Introduce the RewriteCond -x check, which returns
27 true if the pattern is a file with execution permissions.

54 *) mod_usertrack no longer overwrites other cookies.
55 PR 26002. [Scott Moore <apache nopdesign.com>]
57 *) proxy_http fix: mod_proxy hangs when both KeepAlive and
58 ProxyErrorOverride are enabled, and a non-200 response without a
59 body is generated by the backend server. (e.g.: a client makes a
60 request containing the "If-Modified-Since" and "If-None-Match"
61 headers, to which the backend server respond with status 304.)
62 [Graham Wiseman <gwiseman fscinternet.com>, Richard Reiner]
64 *) mod_ssl: Add support for distributed session cache using 'distcache'.
65 [Geoff Thorpe <geoff geoffthorpe.net>]

79 PR: 22951 [Ermanno Scaglione scaglione ..at.. starnetone.de]
81 *) Bring ErrorHeader concept forward from 1.3, so that response
82 header fields can be set for return even on errors or external
85 *) Fix some piped log problems: bogus "piped log program '(null)'
86 failed" messages during restart and problem with the logger
87 respawning again after Apache is stopped. PR 21648, PR 24805.
90 *) Fix <Limit> and <LimitExcept> parsing to require a closing '>'
91 in the initial container. PR 25414.
92 [Geoffrey Young <geoff apache.org>]
94 *) Clean up httpd -V output: Instead of displaying the MPM source
95 directory, display the MPM name and some MPM properties.
96 [Geoffrey Young <geoff apache.org>]
98 *) Fixed cache-removal order in mod_mem_cache.
99 [Jean-Jacques Clar, Cliff Woolley]
101 *) Add fatal exception hook for use by debug modules. The hook is only
102 available if the --enable-exception-hook configure parm is used.
105 *) mod_ssl/mod_status: Re-enable support for output of SSL session
106 cache information in server-status page. [Joe Orton]
108 *) mod_ssl: Remove the shmht session cache, shmcb should be used

121 [Matthieu Estrade <apache moresecurity.org>]
123 *) mod_setenvif: Fix the regex optimizer, which under circumstances
124 treated the supplied regex as literal string. PR 24219.
127 *) Log an error when requests for URIs which fail to map to a valid
128 filesystem name are rejected with 403. [Jeff Trawick]
130 *) Switch to APR 1.0 API.
132 *) Fix mod_include's expression parser to recognize strings correctly
133 even if they start with an escaped token. [André Malo]
135 *) Major overhaul of mod_include's filter parser. The new parser code
136 is expected to be more robust and should catch all of the edge cases
137 that were not handled by the previous one. This includes a binary
138 incompatible change of mod_include's external API. [André Malo]
140 *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
141 PR 14223. [André Malo]
143 *) mod_rewrite: Catch an edge case, where strange subsequent RewriteRules
144 could lead to a 400 (Bad Request) response. [André Malo]
146 *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously
147 the current rewrite state was just used as lookup path, which lead to
148 strange and often useless results. Related to PR 8493. [André Malo]
150 *) Change Listen directive to bind to all addresses when a hostname is
151 not specified. [Justin Erenkrantz]
153 *) Correct failure with Listen directives on machines with IPv6 enabled.
154 [Colm MacCárthaigh <colm stdlib.net>, Justin Erenkrantz]
156 *) Fix a link failure in mod_ssl when the OpenSSL libraries contain
157 the ENGINE functions but the engine header files are missing.
160 *) mod_rewrite: RewriteRules in server context using the force
161 type feature [T=...] no longer disable MultiViews. [André Malo]
163 *) mod_rewrite: Allow piped rewrite logs to be relative to ServerRoot.
166 *) mod_authz_groupfile: Strip trailing spaces of group names. This
167 hopefully saves some hours of searching for typos. PR 12863.
170 *) mod_actions: Propagate the handler name to the action script via
171 the REDIRECT_HANDLER environment variable. [André Malo]
173 *) mod_actions: Introduce the "virtual" modifier to the Action directive,
174 which allows the use of handlers for virtual locations. PR 8431.
177 *) mod_speling: Recognize AcceptPathInfo setting for the particular
178 location. Default is to reject path information. PR 21059.
181 *) mod_ext_filter: Add the ability to filter request bodies.
182 [Philipp Reisner <philipp.reisner linbit.com>]

193 *) prefork MPM: Use the right permissions for the directory created
194 for gprof support. [Jim Carlson <jcarlson jnous.com>]
196 *) Fix a compile failure with recent OpenSSL and picky compilers
197 (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
199 *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
200 the INCLUDE path to be defined properly.
201 PR 11310. [Geoff Thorpe <geoff geoffthorpe.net>]
203 *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
205 *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
206 autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc).
207 [Geoff Thorpe <geoff geoffthorpe.net>]
209 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
210 [Ian Holsman, André Malo]
212 *) mod_negotiation: quality values are now parsed independent from
213 the current locale. level values are now really parsed as integers.
214 PR 17564. [André Malo]
216 *) Extend mod_negotiation to evaluate the environment variables
217 no-gzip and gzip-only-text/html the same way as mod_deflate does.
220 *) mod_rewrite: Fix some problems reporting errors with mapping
221 programs (RewriteMap prg:/something). [Jeff Trawick]
223 *) Return 413 if chunk-ext-header is too long rather than reading from
224 the truncated line. PR 15857. [Justin Erenkrantz]
226 *) Allow restart of httpd to occur even with syntax errors in the config
227 file. PR 16813. [Justin Erenkrantz]

232 *) Remove files on 'make distclean' that should be. PR 15592.
235 *) Allow apachectl to perform status with links and elinks as well.
238 *) Extend the SetEnvIf directive to capture subexpressions of the
239 matched value. [André Malo]
241 *) mod_log_config change optional hook to return previous handler
244 *) Forward port of mod_actions' ability to handle arbitrary methods
245 with the Script directive. [André Malo]
247 *) Let suexec send a message to stderr, if it failed or its policy
248 was violated. This message appears in the error log and allows
249 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
251 *) Modify buildconf to copy all required files into httpd's tree.
252 [Thom May <thom planetarytramp.net>]
254 *) Allow mod_dav to do weak entity comparison functions.
257 *) Move RFC 1413 ident requests from core to new module mod_ident.
260 *) Add mod_authz_owner - a forward port of "Require file-owner"

264 *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
267 *) Replace some of the mutex locking in the worker MPM with
268 atomic operations for higher concurrency. [Brian Pane]
270 *) Allow 'make depend' to work with non-GCC compilers.
273 *) If an httpd.conf has commented out AddModule directives,
274 apxs -i -a will add an un-commented AddModule directive for
275 the new module, which breaks the config.
276 PR: 11212 [Joe Orton]
278 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
280 *) Move the check of the Expect request header field after the hook
281 for ap_post_read_request, since that is the only opportunity for
282 modules to handle Expect extensions. [Justin Erenkrantz]
284 *) Rewrite of aaa modules to an authn/authz model.
285 [Dirk-Willem van Gulik, Justin Erenkrantz]
288 [Apache 2.1.0-dev includes those bug fixes and changes with the
289 Apache 2.0.xx tree as documented, and except as noted, below.]
291 Changes with Apache 2.0.49
293 *) Win32: Add Win32DisableAcceptEx directive. This Windows
294 NT/2000/CP directive is useful to work around bugs in some
295 third party layered service providers like virus scanners,
296 VPN and firewall products, that do not properly handle
297 WinSock 2 APIs. Use this directive if your server is issuing
298 AcceptEx failed messages.

301 *) Make REMOTE_PORT variable available in mod_rewrite.
302 PR 25772. [André Malo]

321 *) mod_rewrite: In external rewrite maps lookup keys containing
322 a newline now cause a lookup failure. PR 14453.
323 [Cedric Gavage <cedric.gavage unixtech.be>, André Malo]
325 *) Backport major overhaul of mod_include's filter parser from 2.1.
326 The new parser code is expected to be more robust and should
327 catch all of the edge cases that were not handled by the previous one.
328 The 2.1 external API changes were hidden by a wrapper which is
329 expected to keep the API backwards compatible. [André Malo]
331 *) Add a hook (insert_error_filter) to allow filters to re-insert
332 themselves during processing of error responses. Enable mod_expires
333 to use the new hook to include Expires headers in valid error
334 responses. This addresses an RFC violation. It fixes PRs 19794,
335 24884, and 25123. [Paul J. Reder]
337 *) Add Polish translation of error messages. PR 25101.
338 [Tomasz Kepczynski <tomek jot23.org>]
340 *) Add AP_MPMQ_MPM_STATE function code for ap_mpm_query. (Not yet
341 supported for BeOS, OS/2, or Win32 MPMs.) [Jeff Trawick,
344 *) Add mod_status hook to allow modules to add to the mod_status
347 *) Fix htdbm to generate comment fields in DBM files correctly.
350 *) mod_dav: Use bucket brigades when reading PUT data. This avoids
351 problems if the data stream is modified by an input filter. PR 22104.
352 [Tim Robbins <tim robbins.dropbear.id.au>, André Malo]
354 *) Fix RewriteBase directive to not add double slashes. [André Malo]
356 *) Improve 'configure --help' output for some modules. [Astrid Keßler]
358 *) Correct UseCanonicalName Off to properly check incoming port number.
361 *) Fix slow graceful restarts with prefork MPM. [Joe Orton]
363 *) Fix a problem with namespace mappings being dropped in mod_dav_fs;
364 if any property values were set which defined namespaces these
365 came out mangled in the PROPFIND response. PR 11637.
366 [Amit Athavale <amit_athavale persistent.co.in>]
368 *) mod_dav: Return a WWW-auth header for MOVE/COPY requests where
369 the destination resource gives a 401. PR 15571. [Joe Orton]
371 *) SECURITY: CAN-2003-0020 (cve.mitre.org)
372 Escape arbitrary data before writing into the errorlog. Unescaped
373 errorlogs are still possible using the compile time switch
374 "-DAP_UNSAFE_ERROR_LOG_UNESCAPED". [Geoffrey Young, André Malo]
376 *) mod_autoindex / core: Don't fail to show filenames containing
377 special characters like '%'. PR 13598. [André Malo]
379 *) mod_status: Report total CPU time accurately when using a threaded
380 MPM. PR 23795. [Jeff Trawick]

383 proxy operations. PR 24991. [Larry Toppi <larry.toppi citrix.com>]
385 *) Win32 MPM: Implement MaxMemFree to enable setting an upper
386 limit on the amount of storage used by the bucket brigades
387 in each server thread. [Bill Stoddard]
389 *) Modified the cache code to be header-location agnostic. Also
390 fixed a number of other cache code bugs related to PR 15852.
391 Includes a patch submitted by Sushma Rai <rsushma novell.com>.
392 This fixes mod_mem_cache but not mod_disk_cache yet so I'm not
393 closing the PR since that is what they are using. [Paul J. Reder]
395 *) complain via error_log when mod_include's INCLUDES filter is
396 enabled, but the relevant Options flag allowing the filter to run
397 for the specific resource wasn't set, so that the filter won't
398 silently get skipped. next remove itself, so the warning will be
399 logged only once [Stas Bekman, Jeff Trawick, Bill Rowe]
401 *) mod_info: HTML escape configuration information so it displays
402 correctly. PR 24232. [Thom May]

416 *) mod_ssl: Fix segfaults at startup if other modules which use OpenSSL
417 are also loaded. [Joe Orton]
419 *) mod_ssl: Use human-readable OpenSSL error strings in logs; use
420 thread-safe interface for retrieving error strings. [Joe Orton]
422 *) mod_expires: Initialize ExpiresDefault to NULL instead of "" to
423 avoid reporting an Internal Server error if it is used without
424 having been set in the httpd.conf file. PR: 23748, 24459
425 [Andre Malo, Liam Quinn <liam htmlhelp.com>]
427 *) mod_autoindex: Don't omit the <tr> start tag if the SuppressIcon
428 option is set. PR 21668. [Jesse Tie-Ten-Quee <highos highos.com>]

442 config file name. [Aryeh Katz <aryeh secured-services.com>]
444 *) Set the scoreboard state to indicate logging prior to running

446 instead of 'W'. [Jeff Trawick]
448 Changes with Apache 2.0.48
450 *) SECURITY [CAN-2003-0789]: mod_cgid: Resolve some mishandling of
451 the AF_UNIX socket used to communicate with the cgid daemon and
452 the CGI script. [Jeff Trawick]

455 mod_rewrite which occurred if one configured a regular expression
456 with more than 9 captures. [André Malo]

459 set, for example, when processing some error conditions.
460 PR 23836. [Brian Akins <bakins web.turner.com>, André Malo]
462 *) fix the config parser to support <Foo>..</Foo> containers (no
463 arguments in the opening tag) supported by httpd 1.3. Without
464 this change mod_perl 2.0's <Perl> sections are broken.
465 ["Philippe M. Chiasson" <gozer cpan.org>]
467 *) mod_cgid: fix a hash table corruption problem which could
468 result in the wrong script being cleaned up at the end of a

476 PR 23416. [André Malo]
478 *) mod_rewrite: Fix mod_rewrite's support of the [P] option to send

480 fields in the rewritten URI. PR: 13946.
481 [Eider Oliveira <eider bol.com.br>]
483 *) cache_util: Fix ap_check_cache_freshness to check max_age, smax_age, and
484 expires as directed in RFC 2616. [Thomas Castelle <tcastelle generali.fr>]

514 *) Fix a bug, where mod_deflate sometimes unconditionally compressed the
515 content if the Accept-Encoding header contained only other tokens than
516 "gzip" (such as "deflate"). PR 21523. [Joe Orton, André Malo]
518 *) Avoid an infinite recursion, which occured if the name of an included
519 config file or directory contained a wildcard character. PR 22194.

1145 HSE_STATUS_PENDING. This only affected isapi .dll's configured
1146 with the ISAPIFakeAsync on directive. PR 11918
1147 [John DeSetto <jdesetto radiantsystems.com>, William Rowe]
1149 *) mod_isapi: Fix the issue where all results from mod_isapi would
1150 run through the core die handler resulting in invalid responses
1151 or access log entries. PR 10216 [William Rowe]
1153 *) Improves the user friendliness of the CacheRoot processing
1154 over my last pass. This version avoids the pool allocations
1155 but doesn't avoid all of the runtime checks. It no longer
1156 terminates during post-config processing. An error is logged
1157 once per worker, indicating that the CacheRoot needs to be set.
1160 *) Fix a bug where we keep files open until the end of a
1161 keepalive connection, which can result in:
1162 (24)Too many open files: file permissions deny server access
1163 especially on threaded servers. [Greg Ames, Jeff Trawick]
1165 *) Fix a bug in which mod_proxy sent an invalid Content-Length
1166 when a proxied URL was invoked as a server-side include within
1167 a page generated in response to a form POST. [Brian Pane]
1169 *) Added code to process min and max file size directives and to
1170 init the expirychk flag in mod_disk_cache. Added a clarifying
1171 comment to cache_util. [Paul J. Reder]
1173 *) The value emitted by ServerSignature now mimics the Server HTTP
1174 header as controlled by ServerTokens. [Francis Daly <deva daoine.org>]
1176 *) Gracefully handly retry situations in the SSL input filter,
1177 by following the SSL libraries' retry semantics.
1180 *) Terminate CGI scripts when the client connection drops. This
1181 fix only applies to some normal paths in mod_cgi. mod_cgid
1182 is still busted. PR 8388 [Jeff Trawick]
1184 *) Fix a bug where 416 "Range not satisfiable" was being
1185 returned for content that should have been redirected.
1188 *) Fix memory leak in mod_ssl from internal SSL library allocations
1189 within SSL_get_peer_certificate and X509_get_pubkey.
1190 [Zvi Har'El <rl math.technion.ac.il>
1191 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>].
1193 *) mod_ssl uses free() inappropriately in several places, to free
1194 memory which has been previously allocated inside OpenSSL.
1195 Such memory should be freed with OPENSSL_free(), not with free().

1197 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>].
1199 *) Emit a message to the error log when we return 404 because
1200 the URI contained '%2f'. (This was previously nastily silent
1201 and difficult to debug.) [Ken Coar]
1203 *) Fix streaming output from an nph- CGI script. CGI:IRC now
1204 works. PR 8482 [Jeff Trawick]
1206 *) More accurate logging of bytes sent in mod_logio when
1207 the client terminates the connection before the response
1208 is completely sent [Bojan Smojver <bojan rexursive.com>]
1210 *) Fix some problems in the perchild MPM.
1211 [Jonas Eriksson <jonas webkonsulterna.com>]
1213 *) Change the CacheRoot processing to check for a required
1214 value at config time. This saves a lot of wasted processing
1215 if the mod_disk_cache module is loaded but no CacheRoot
1216 was provided. This fix also adds code to log an error
1217 and avoid useless pallocs and procesing when the computed
1218 cache file name cannot be opened. This also updates the
1219 docs accordingly. [Paul J. Reder]
1221 *) Introduce the EnableSendfile directive, allowing users of NFS
1222 shares to disable sendfile mechanics when they either fail
1223 outright or provide intermitantly corrupted data. PR
1226 *) Resolve the error "An operation was attempted on something
1227 that is not a socket. : winnt_accept: AcceptEx failed.
1228 Attempting to recover." for users of various firewall and
1229 anti-virus software on Windows. PR 8325 [William Rowe]
1231 *) Add the ProxyBadHeader directive, which gives the admin some
1232 control on how mod_proxy should handle bogus HTTP headers from
1233 proxied servers. This allows 2.0 to "emulate" 1.3's behavior if
1234 desired. [Jim Jagielski]
1236 *) Change the LDAP modules to export their symbols correctly
1237 during a Windows build. Add dsp files for Windows. Update
1238 README.ldap file for Windows build instructions.
1239 [Andre Schild <A.Schild aarboard.ch>]
1241 *) Performance improvements for the code that generates HTTP
1242 response headers [Brian Pane]
1244 *) Add -S as a synonym for -t -DDUMP_VHOSTS.

1255 [John K. Sterling <john sterls.com>, Justin Erenkrantz]
1257 Changes with Apache 2.0.43
1259 *) SECURITY [CAN-2002-0840]: HTML-escape the address produced by
1260 ap_server_signature() against this cross-site scripting
1261 vulnerability exposed by the directive 'UseCanonicalName Off'.
1262 Also HTML-escape the SERVER_NAME environment variable for CGI
1263 and SSI requests. It's safe to escape as only the '<', '>',
1264 and '&' characters are affected, which won't appear in a valid
1265 hostname. Reported by Matthew Murphy <mattmurphy kc.rr.com>.
1268 *) Fix a core dump in mod_cache when it attemtped to store uncopyable
1269 buckets. This happened, for instance, when a file to be cached
1270 contained SSI tags to execute a CGI script (passed as a pipe
1271 bucket). [Paul J. Reder]
1273 *) Ensure that output already available is flushed to the network
1274 when the content-length filter realizes that no new output will
1275 be available for a while. This helps some streaming CGIs as
1276 well as some other dynamically-generated content. [Jeff Trawick]
1278 *) Fix a mutex problem in mod_ssl session cache support which
1279 could lead to an infinite loop. PR 12705

1284 a location where both DAV and CGI are enabled. [Ryan Bloom]
1286 *) Allow the UserDir directive to accept a list of directories.
1287 This matches what Apache 1.3 does. Also add documentation for
1288 this feature. [Jay Ball <jay veggiespam.com>]
1290 *) New Module: mod_logio. adds the ability to log bytes sent and
1291 received. [Bojan Smojver <bojan rexursive.com>]

1298 [Thomas Bennett <thomas.bennett eds.com>, Graham Leggett]
1300 *) Make sure the contents of the WWW-Authenticate header is

1308 *) Make mod_cache's CacheMaxStreamingBuffer directive work
1309 properly for virtual hosts that override server-wide mod_cache
1310 setttings. [Matthieu Estrade <estrade-m ifrance.com>]
1312 *) Add -p option to apxs to allow programs to be compiled with apxs.
1315 Changes with Apache 2.0.42
1317 *) mod_dav: Check for versioning hooks before using them.
1320 Changes with Apache 2.0.41
1322 *) The protocol version (eg: HTTP/1.1) in the request line parsing
1323 is now case insensitive. [Jim Jagielski]
1325 *) Allow AddOutputFilterByType to add multiple filters per directive.
1328 *) Remove warnings with Sun's Forte compiler. [Justin Erenkrantz]
1330 *) Fixed mod_disk_cache's generation of 304s
1331 [Kris Verbeeck <Kris.Verbeeck ubizen.com>]
1333 *) Add support for using fnmatch patterns in the final path
1334 segment of an Include statement (eg.. include /foo/bar/*.conf).
1335 and remove the noise on stderr during config dir processing.
1336 [Joe Orton <jorton redhat.com>]
1338 *) mod_cache: cache_storage.c. Add the hostname and any request
1339 args to the key generated for caching. This provides a unique
1340 key for each virtual host and for each request with unique
1341 args. [Paul J. Reder, args code provided by Kris Verbeeck]
1343 *) mod_cache: Do not cache responses to GET requests with query

1383 PR 12132,12181,12172.
1384 [Ian Holsman / Rob Cromwell <apachechangelog robcromwell.com>]
1386 *) The content-length filter no longer tries to buffer up
1387 the entire output of a long-running request before sending
1388 anything to the client. [Brian Pane]
1390 *) Win32: Lower the default stack size from 1MB to 256K. This will
1391 allow around 8000 threads to be started per child process.
1392 'EDITBIN /STACK:size apache.exe' can be used to change this
1393 value directly in the apache.exe executable.
1396 *) Win32: Implement ThreadLimit directive in the Windows MPM.
1399 *) Remove CacheOn config directive since it is set but never checked.
1400 No sense wasting cycles on unused code. Besides, the only truly
1401 bug free code is deleted code. :) [Paul J. Reder]
1403 *) BufferLogs are now run-time enabled, and the log_config now has 2 new
1404 callbacks to allow a 3rd party module to actually do the writing of the
1405 log file [Ian Holsman]
1407 *) Correct ISAPIReadAheadBuffer to default to 49152, per mod_isapi docs.

1417 Also Surfaced this directive in the standard config (default FULL)
1420 *) Change mod_rewrite to use apr-util's dbm support for dbm rewrite
1421 maps. The dbm type (e.g., ndbm, gdbm) can be specified on the
1422 RewriteMap directive. PR 10644 [Jeff Trawick]
1424 *) Fixed mod_rewrite's RewriteMap prg: support so that request/response
1425 pairs will no longer get out of sync with each other. PR 9534
1428 *) Fixes required to get quoted and escaped command args working in
1429 mod_ext_filter. PR 11793 [Paul J. Reder]

1441 *) thread safety & proxy-ftp [Alexey Panchenko <alexey liwest.ru>, Ian Holsman]
1443 *) mod_disk_cache works much better. This module should still
1444 be considered experimental. [Eric Prud'hommeaux]
1446 *) Performance improvement for keepalive requests: when setting
1447 aside a small file for potential concatenation with the next
1448 response on the connection, set aside the file descriptor rather
1449 than copying the file into the heap. [Brian Pane]
1451 *) Modified version check on openssl so that it finds the executable
1452 first and then performs a check of the version, only warning the
1453 user if they chose, or we selected, an old version of OpenSSL.
1454 This change also allows the code to work for non-openssl libraries
1455 selected via the --with-ssl=dir option, which can override the
1456 automated library check in any case. [Roy Fielding]
1458 Changes with Apache 2.0.40
1460 *) SECURITY [CAN-2002-0661] (cve.mitre.org):
1461 Close a very significant security hole that
1462 applies only to the Win32, OS2 and Netware platforms. Unix was not
1463 affected, Cygwin may be affected. Certain URIs will bypass security
1464 and allow users to invoke or access any file depending on the system
1465 configuration. Without upgrading, a single .conf change will close
1466 the vulnerability. Add the following directive in the global server
1467 httpd.conf context before any other Alias or Redirect directives;
1468 RedirectMatch 400 "\\\.\."
1469 Reported by Auriemma Luigi <bugtest sitoverde.com>.
1472 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1473 Close a path-revealing exposure in multiview type
1474 map negotiation (such as the default error documents) where the
1475 module would report the full path of the typemapped .var file when
1476 multiple documents or no documents could be served based on the mime
1477 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
1480 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1481 Close a path-revealing exposure in cgi/cgid when we
1482 fail to invoke a script. The modules would report "couldn't create
1483 child process /path-to-script/script.pl" revealing the full path
1484 of the script. Reported by Jim Race <jrace qualys.com>.
1487 *) Set aside the apr-iconv and apr_xlate() features for the Win32
1488 build of 2.0.40 so development can be completed. A patch, from
1489 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
1490 will be available for those that wish to work with apr-iconv.
1493 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
1494 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
1496 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
1497 set to 1, so we can exclude things from the general case with
1498 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
1500 *) Accept multiple leading /'s for requests within the DocumentRoot.
1501 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
1503 *) Solved the reports of .pdf byterange failures on Win32 alone.
1504 APR's sendfile for the win32 platform collapses header and trailer
1505 buffers into a single buffer. However, we destroyed the pointers
1506 to the header buffer if a trailer buffer was present. PR 10781
1509 *) mod_ext_filter: Add the ability to enable or disable a filter via
1510 an environment variable. Add the ability to register a filter of
1511 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
1513 *) Restore the ability to specify host names on Listen directives.
1514 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh yahoo.com>]
1516 *) When deciding on the default address family for listening sockets,
1517 make sure we can actually bind to an AF_INET6 socket before
1518 deciding that we should default to AF_INET6. This fixes a startup
1519 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
1521 *) Replace usage of atol() to parse strings when we might want a
1522 larger-than-long value with apr_atoll(), which returns long long.
1523 This allows HTTPD to deal with larger files correctly.
1524 [Shantonu Sen <ssen apple.com>]
1526 *) mod_ext_filter: Ignore any content-type parameters when checking if
1527 the response should be filtered. Previously, "intype=text/html"
1528 wouldn't match something like "text/html;charset=8859_1".
1531 *) mod_ext_filter: Set up environment variables for external programs.
1532 [Craig Sebenik <craig netapp.com>]
1534 *) Modified the HTTP_IN filter to immediately append the EOS (end of
1535 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
1536 the caller to determine that no content remains without prefetching
1537 additional POST body. [William Rowe]

1562 *) APR-Util Renames pending have been completed [Thom May]
1564 *) Performance improvements for the code that reads request
1565 headers (ap_rgetline_core() and related functions) [Brian Pane]
1567 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
1568 to configure the maximum amount of memory the allocators will
1569 hold on to for reuse. Anything over the MaxMemFree threshold
1570 will be free()d. This directive is useful when uncommon large
1571 peaks occur in memory usage. It should _not_ be used to mask
1572 defective modules' memory use. [Sander Striker]
1574 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
1575 scripts would not result in a truncated response.
1576 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
1578 *) Add a filter_init parameter to the filter registration functions
1579 so that a filter can execute arbitrary code before the handlers
1580 are invoked. This resolves a problem where mod_include requests
1581 would incorrectly return a 304. [Justin Erenkrantz]
1583 *) Fix a long-standing bug in 2.0, CGI scripts were being called
1584 with relative paths instead of absolute paths. Apache 1.3 used
1585 absolute paths for everything except for SuExec, this brings back
1586 that standard. [Ryan Bloom]
1588 *) Fix infinite loop due to two HTTP_IN filters being present for
1589 internally redirected requests. PR 10146. [Justin Erenkrantz]
1591 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
1594 *) Fix mod_ext_filter to look in the main server for filter definitions
1595 when running in a vhost if the filter definition is not found in
1596 the vhost. PR 10147 [Jeff Trawick]
1598 *) Support WinNT CGI invocation through ScriptInterpreterSource
1599 'registry' for script interpreter paths and names with non-ascii
1600 characters in the executable filepath. [William Rowe]
1602 *) Support the -w flag on to keep the Win32 console open on error.
1605 *) Normalize the hostname value in the request_rec to all-lowercase
1606 [Perry Harrington <pedward webcom.com>]
1608 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
1609 extended characters (non US-ASCII) in non-utf8 format. This brings
1610 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
1611 to the cgi application itself. [William Rowe]
1613 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
1614 modules to bring them up to the current apr/apr-util APIs.
1617 *) Fix segfault in mod_mem_cache most frequently observed when
1618 serving the same file to multiple clients on an MP machine.
1621 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
1622 [Brian Degenhardt <bmd mp3.com>, Ian Holsman]
1624 *) Fix perchild to work with apachectl by adding -k support to perchild.

1627 *) Fix a silly htpasswd.c logic error that incorrectly reported that
1628 both -c and -n had been used. PR 9989 [Cliff Woolley]
1630 *) Fixed a mod_include error case in which no HTTP response was sent
1631 to the client if an shtml document contained an unterminated SSI
1632 directive [Brian Pane]
1634 *) Improve ap_get_client_block implementation by using APR-util brigade
1635 helper functions and relying on current filter assumptions.
1638 Changes with Apache 2.0.39
1640 *) Fixed a build problem in htpasswd.c on Win32.

1643 Changes with Apache 2.0.38
1645 *) Rewrite htpasswd to use APR. The removes the annoying warning about
1646 tmpnam being unsafe. [Ryan Bloom]
1648 *) We must set the MIME-type for .shtml files to text/html if we want them
1649 to be parsed for SSI tags. Add the config for that to the default
1650 config file so that it is easier to enable .shtml parsing.
1651 [Dave Dyer <ddyer real-me.net>]
1653 *) Fixed a problem with 'make install' on ReliantUnix.
1654 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
1656 *) Make the default_handler catch all requests that aren't served by
1657 another handler. This also gets us to return a 404 if a directory
1658 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1659 loaded. [Justin Erenkrantz]
1661 *) Fixed the handling of nested if-statements in shtml files.
1662 PR 9866 [Brian Pane]
1664 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1665 into a directory different from the one that was configured. This
1666 also mirrors the root= feature from 1.3. We cannot use prefix=,
1667 because both APR and APR-util resolve their installation paths at
1668 configuration time. This means that there is no variable prefix
1669 to replace. [Andreas Hasenack <andreas netbank.com.br>]
1671 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1672 These levels of AIX don't have a thundering herd problem with
1673 accept(). [Jeff Trawick]
1675 *) prefork MPM: Ignore mutex errors during graceful restart. For
1676 certain types of mutexes (particularly SysV semaphores), we
1677 should expect to occasionally fail to obtain or release the
1678 mutex during restart processing. [Jeff Trawick]
1680 *) Fix install-bindist.sh so that it finds any perl instead of just
1681 early perl 5.x versions. This is consistent with a build/install
1682 from source, and it allows the perl scripts installed by a bindist
1683 to work on systems with perl 5.6. [Jeff Trawick]
1685 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
1686 Tru64 (and probably some other platforms). [Jeff Trawick]
1688 *) Allow CGI scripts to return their Content-Length. This also fixes a
1689 hang on HEAD requests seen on certain platforms (such as FreeBSD).

1700 *) allow POST method over SSL when per-directory client cert
1701 authentication is used with 'SSLOptions +OptRenegotiate' enabled
1702 and a client cert was found in the ssl session cache.
1704 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
1705 session cache when there is no cert chain in the cache. prior to
1706 the fix this situation would result in a FORBIDDEN response and
1707 error message "Cannot find peer certificate chain"

1751 it has sent an EOS bucket up the stack, if so, it will only ever
1752 send an EOS bucket for this request.

1755 *) Remove all special mod_ssl URIs. This also fixes the bug where
1756 redirecting (.*) will allow an SSL protected page to be viewed
1757 without SSL. [Ryan Bloom]

2045 explicitly tell the server that warning messages should be sent
2046 to the client in addition to being recorded in the error log.
2047 Prior to this change, ap_log_rerror() always sent warning
2048 messages to the client. In one case, a faulty CGI script caused
2049 the server to send a warning message to the client that contained
2050 the full path to the CGI script. This could be considered a
2051 minor security exposure. [Bill Stoddard]
2053 *) mod_autoindex output when SuppressRules was specified would
2054 omit the first carriage return so the first item in the list

2067 *) Change instdso.sh to use libtool --install everywhere and then
2068 clean up some stray files and symlinks that libtool leaves around
2069 on some platforms. This gets subversion building properly since
2070 it needed a re-link to be performed by libtool at install time,
2071 and the old instdso.sh logic to simply cp the DSO didn't handle
2072 that requirement. [Sander Striker]

2084 cache entry. [Bill Stoddard]
2086 *) Introduced -E startup_logfile_name option to httpd to allow admins
2087 to begin logging errors immediately. This provides Win32 users
2088 an alternative to sending startup errors to the event viewer, and

2178 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
2179 cause the Apache parent process to run in the foreground (similar to
2180 -DNO_DETACH except that it doesn't switch session ids).
2183 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
2184 for those platforms that support it. If using the default
2185 implementation, this is between pthread and sysvsem in priority.
2186 This implies it's the new default for Darwin. [Jim Jagielski]

2268 the original site Server header with it's own, which is not
2269 allowed by RFC2616. Fixed. [Graham Leggett]
2271 *) Fix a mod_cgid problem that left daemon processes stranded
2272 in some server restart scenarios. [Jeff Trawick]
2274 *) Added exp_foo and rel_foo variables to config_vars.mk for
2275 all Apache and Autoconf path variables (like --sysconfdir,
2276 --sbindir, etc). exp_foo is the "expanded" version, which means
2277 that all internal variable references have been interpolated.
2278 rel_foo is the same as $exp_foo, only relative to $prefix if they
2279 share a common path. [Aaron Bannert]
2281 *) Fix some restart/terminate problems in the worker MPM. Don't
2282 drop connections during graceful restart. [Jeff Trawick]
2284 *) Change the header merging behaviour in proxy, as some headers
2285 (like Set-Cookie) cannot be unmerged due to stray commas in
2286 dates. [Graham Leggett]
2288 *) Be more vocal about what AcceptMutex values we allow, to make
2289 us closer to how 1.3 does it. [Jim Jagielski]
2291 *) Get nph- CGI scripts working again. PRs 8902, 8907, 9983
2294 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
2296 *) Add accessor function to set r->content_type. From now on,
2297 ap_rset_content_type() should be used to set r->content_type.
2298 This change is required to properly implement the
2299 AddOutputFilterByType configuration directive.
2300 [Bill Stoddard, Sander Striker, Ryan Bloom]
2302 *) Add new M_FOO symbols for the WebDAV/DeltaV methods specified by
2303 RFC 3253. Improved the method name/number mapping functions.
2306 *) remove sock_enable_linger from connection.c [Ian Holsman]
2308 *) Fix for virtual host processing where the requested hostname
2309 has a '.' at the end (PR 9187) [Ryan Cruse <ryan estara.com>]
2311 *) mod_dav's APIs for REPORT response handling was changed so that
2312 providers can generate the content directly into the output filter
2313 stack, rather than buffering the response into memory. [Greg Stein]
2315 *) Fix a hang condition with graceful restart and prefork MPM
2316 in the situation where MaxClients is very high but
2317 much fewer servers are actually started at the time of the
2318 restart. [Jeff Trawick]
2320 *) Small performance fixes for mod_include [Brian Pane]
2322 *) Performance improvement for the error logger [Brian Pane]
2324 *) Change configure so that Solaris 8 and above have
2325 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
2326 according to sun people solaris 8+ doesn't have a thundering
2327 herd problem [Ian Holsman]
2329 *) Allow URIs specifying CGI scripts to include '/' at the end
2330 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
2331 which ignore '/' at the end of the names of non-directories).
2332 PR 10138 [Jeff Trawick]
2334 *) implement SSLSessionCache shmht and shmcb based on apr_rmm and
2335 apr_shm. [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
2337 *) Fix apxs -g handling. Move config_vars.mk from the top build
2338 directory to the build directory. PR 10163 [Jeff Trawick]
2340 *) Fix some mod_include problems which broke evaluation of some
2341 expressions. PR 10108 [Jeff Trawick]
2343 *) Fix the calculation of request time in mod_status. [Stas Bekman]
2345 *) Fix the calculation of thread_num in the worker score structure.
2348 *) Use apr_atomic operations in managing the mod_mem_cache
2349 cache_objects for SMP scalability. (see USE_ATOMICS
2350 preprocessor directive in mod_file_cache)
2353 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
2354 preprocessor directive in mod_file_cache)
2357 *) Implement prototype mod_disk_cache for use with mod_cache.
2360 *) Add a missing manualdir entry in the Debian config.layout.
2361 [Thom May <thom planetarytramp.net>]
2363 *) Stop installing libtool for APR and tell APR where it should place
2364 its copy of libtool (via our installbuildpath layout variable).
2367 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
2368 when reading from a remote HTTP server in proxy. [Graham Leggett]
2370 *) Modify receive/send loop in proxy_http and proxy_ftp so that
2371 should it be necessary, the remote server socket is closed before
2372 transmitting the last buffer (set by ProxyIOBufferSize) to the
2373 client. This prevents the backend server from being forced to hang
2374 around while the last few bytes are transmitted to a slow client.
2375 Fix the case where no error checking was performed on the final
2376 brigade in the loop. [Graham Leggett]
2378 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
2379 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
2380 hours. [Graham Leggett, Bill Stoddard]
2382 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
2383 for a undefined variable. [Ian Holsman]
2385 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
2386 when we can't get a socket in the specified address family. We may
2387 have gotten back an IPv6 address first and yet our system is not
2388 configured to allow IPv6 sockets. [Jeff Trawick]
2390 *) Be more careful about recursively removing CVS directories. Make
2391 sure that we aren't cd'ing to their home directory first. PR: 9993
2392 [Aaron Bannert, James LewisMoss <dres lewismoss.net>]
2394 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
2395 [Dirk-Jan Faber <dirk-jan selwerd.nl>, Aaron Bannert,
2396 Thom May <thom planetarytramp.net>]
2398 *) Rename the filter ordering priorities. The recent filtering fixes
2399 have showcased problems with their usage. Therefore, we need to
2400 rename them to increase the clarity. (CONTENT->RESOURCE,
2401 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
2403 Changes with Apache 2.0.33
2405 *) Fix a problem in the new --enable-layout functionality where
2406 it wouldn't allow overrides from variables like --prefix,
2407 --bindir, etc. [Thom May <thom planetarytramp.net>]
2409 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
2410 no longer hangs around waiting for the socket to close before
2411 returning exhaustive data. [Aaron Bannert]
2413 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
2414 [Thom May <thom planetarytramp.net>]
2416 *) Change mod_ssl to always do a full startup/teardown on restarts.
2417 this allows mod_ssl to be added to a server that is already
2418 running and makes it possible to add/change certs/keys after the
2419 server has been started. [Doug MacEachern]
2421 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
2422 This pipe must be a bidirectional 'console' style relay, which
2423 mod_ssl prints all prompts to the pipe's stdin, and reads the
2424 passphrases from the pipe's stdout. [William Rowe]
2426 *) Fix bug where --sysconfdir and --localstatedir were being
2427 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
2430 *) Fix --enable-layout to work again. Caution: When specifying
2431 --enable-layout, common arguments like --prefix, --exec-prefix,
2432 etc. will be ignored and the settings from the layout will be
2433 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]
2436 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
2437 regex pattern matching for the determination of which requests
2438 to use the remote proxy for. [Jim Jagielski]
2440 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
2442 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
2443 cruft in piped logs and rewritemap child processes.
2446 *) All instances of apr_lock_t have been removed and converted
2447 to one of the following new lock APIs: apr_thread_mutex.h,
2448 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
2449 use the apr_lock.h API, as the old API will soon be deprecated.
2452 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
2453 [Ralf S. Engelschall, Cliff Woolley]
2455 *) mod-include: make it handle flush'es and fix the 'false-alarm'
2456 [Justin Erenkrantz, Brian Pane, Ian Holsman]
2458 *) ap_get_*_filter_handle() functions to allow 3rd party modules
2459 to lookup filter handles so they can bypass the filter name
2460 lookup when adding filters to a request (via ap_add_*_filter_handle())
2461 [Ryan Morgan <rmorgan covalent.net>]
2463 *) Fix for multiple file buckets on Win32, where the first file
2464 bucket would cause the immediate closure of the socket on any
2465 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
2467 *) Correct Win32 failure of mmap of a segment beyond start of the
2468 file; fixes large SSL and similar transfers. [William Rowe]
2471 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
2472 multi-process mode to not "daemonize" while detaching from the
2473 controlling terminal. This is necessary for Apache to work with
2474 process-management tools like AIX's "System Resource Controller"
2475 as well as Dan Bernstein's "daemontools".
2476 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
2478 *) Convert mod_auth_digest to use the new apr_global_mutex_t
2479 type. [Aaron Bannert]
2481 *) fix bug in mod-include where it wouldn't send a unmatched
2482 part if it was at the end of a bucket [Ian Holsman]
2484 *) worker MPM: Improve logging of errors with the interface between
2485 the listener thread and worker threads. [Jeff Trawick]
2487 *) Some browsers ignore cookies that have been merged into a
2488 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
2489 are now unmerged in the http proxy before being sent to the
2490 client. [Graham Leggett]
2492 *) Fix a problem with proxy where each entry of a duplicated
2493 header such as Set-Cookie would overwrite and obliterate the
2494 previous value of the header, resulting in multiple header
2495 values (like cookies) going missing.
2496 [Graham Leggett, Joshua Slive]
2498 *) Add the server-limit and thread-limit values to the scoreboard
2499 for the sake of third-party applications.
2500 [Adam Sussman <myddryn vishnu.vidya.com>]
2502 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
2504 *) OS/390: Get make install to properly copy DSO modules.
2507 *) Win32: Fix bug in mod_status with displaying "Restart Time"
2508 and "Server uptime".
2511 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
2513 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
2515 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
2516 [David MacKenzie <djm pix.net>]
2518 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
2519 [David MacKenzie <djm pix.net>]
2521 *) Fix segfault and display error when SSLMutex file can not be
2522 created. [Adam Sussman <myddryn vishnu.vidya.com>]
2524 *) Add reference counting to mod_mem_cache cache objects to
2525 better manage removing objects from the cache.
2528 *) Change the verbage on the ScoreBoardFile in our default configs.
2529 Also change the default to be commented out (unspecified) so we
2530 get anonymous shared memory by default. [Aaron Bannert]
2532 *) Implement new ScoreBoardFile directive logic. This affects how
2533 we create the scoreboard's shared memory segment. If the directive
2534 is present, a name-based segment is created. If the directive is
2535 not present, first an anonymous segment is created, and if that
2536 fails, a name-based segment is created from a file of the name
2537 DEFAULT_SCOREBOARD. This gives third-party applications the
2538 ability to access our scoreboard. [Aaron Bannert]
2540 *) Allow mod_deflate to work with non-GET requests and properly send
2541 Content-Lengths. [Sander Striker <striker apache.org>]
2543 *) Fix ap_directory_merge() to correctly merge configs when there is
2544 no <Directory /> block. [Justin Erenkrantz, William Rowe]
2546 *) Remove spurious debug messsages that are normal under HTTP
2547 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
2549 *) Fix a bug in mod_cgid that would prevent proper shutdown death
2550 of the cgid process. [Aaron Bannert]
2552 *) Add signal handling back in to the worker MPM for the one_process
2553 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
2555 *) Performance: Reuse per-connection transaction pools in the
2556 worker MPM, rather than destroying and recreating them. [Brian Pane]
2558 *) Remove all signals from the worker MPM's child process. Instead,
2559 the parent uses the Pipe of Death for all communication with the
2560 child processes. [Ryan Bloom]
2562 Changes with Apache 2.0.32
2564 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
2565 default if the directive is not specified. This mirrors older
2566 behavior without changes to the httpd.conf. [William Rowe]
2568 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
2569 the service, mpm and logging code, and bugs in apr_file_open_stderr
2570 and apr_file_dup2 functions. Win2K/XP services have no handles
2571 associated for stdin/out/err, which caused unpredictable behavior
2572 in the prior release. [William Rowe, Bill Stoddard]
2574 *) Win32: simplify the Application Event Log messages, since there isn't
2575 likely to be 'more information in the error log' before an error log
2576 has been opened. [William Rowe]
2578 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
2579 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
2581 *) Win32: apache -k shutdown now behaves like apache -k stop.
2584 *) Fix prefork to not kill the parent if a child hits a resource shortage
2585 on accept(). [Greg Ames]
2587 *) Fix seg faults that occur when what should be the httpd request line
2588 starts with \r\n followed by garbage. [Greg Ames]
2590 *) Allow statically linked support binaries with the new
2591 --enable-static-support flag, and enable this behavior in
2592 the binbuild script. Also add a new --enable-static-htdbm
2593 flag. [Aaron Bannert]
2595 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
2596 do only one stat() call when generating the directory listings.
2599 *) Fix resolve_symlink to save the original symlink name if known.
2602 *) Be a bit more sane with regard to CanonicalNames. If the user has
2603 specified they want to use the CanonicalName, but they have not
2604 configured a port with the ServerName, then use the same port that
2605 the original request used. [Ryan Bloom and Ken Coar]
2607 *) In core_input_filter, check for an empty brigade after
2608 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
2609 client says it will post some data but we get FIN before any
2610 data arrives. [Jeff Trawick]
2612 *) Not being able to bind to the socket is a fatal error. We should
2613 print an error to the console, and return a non-zero status code.
2614 With these changes, all of the Unix MPMs do that correctly.
2617 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
2618 through to CGI scripts. PR 9163
2619 [Brian Reid <breid customlogic.com>,
2620 Zvi Har'El <rl math.technion.ac.il>]
2622 *) binbuild.sh: Make sure that we use the expat from our source
2623 tree so that there aren't any surprises on the target machine.
2626 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2627 enough to keep up with new requests. Start using
2628 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2629 when we can't talk to the daemon. [Jeff Trawick]
2631 *) apxs: LTFLAGS envvar can override default libtool options. Try
2632 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2633 the covers. [Jeff Trawick]
2635 *) The Location: response header field, used for external
2636 redirect, *must* be an absoluteURI. The Redirect directive
2637 tested for that, but RedirectMatch didn't -- it would allow
2638 almost anything through. Now it will try to turn an abs_path
2639 into an absoluteURI, but it will correctly varf like Redirect
2640 if the final redirection target isn't an absoluteURI. [Ken Coar]
2642 Changes with Apache 2.0.31
2644 *) Create the scoreboard (in the parent) in a global pool context,
2645 so it survives graceful restarts. This fixes a SEGV during
2646 graceful restarts. [Aaron Bannert]
2648 *) Add a timeout option to the proxy code 'ProxyTimeout'
2651 *) FTP directory listings are now always retrieved in ASCII mode.
2652 The FTP proxy properly escapes URI's and HTML in the generated
2653 listing, and escapes the path components when talking to the FTP
2654 server. It is now possible to browse the root directory by using
2655 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2656 Also, the last path component may contain wildcard characters
2657 '*' and '?', and if they do, a directory listing is created instead
2658 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2661 *) Added single-listener unserialized accept support to the
2662 worker MPM [Brian Pane]
2664 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2665 the incoming host header through to the proxied server
2666 [Geoff <g.russell ieee.org>]
2668 *) New Directive Option for ProxyPass. It now can block a location
2669 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
2671 *) Don't let the default handler try to serve a raw directory. At
2672 best you get gibberish. Much worse things can happen depending
2673 on the OS. [Jeff Trawick]
2675 *) Change the pre_config hook to return a value. Modules can now emit
2676 an error message and then cause the server to quit gracefully during
2677 startup. This required a bump to the MMN. [Aaron Bannert]
2679 *) Fix some unix socket descriptor leaks in the handler side of
2680 mod_cgid (the part that runs in the server process). Whack a
2681 silly "close(-1)" in the handler too. [Jeff Trawick]
2683 *) Change the pre_mpm hook to return a value, so that scoreboard
2684 init errors percolate up to code that knows how to exit
2685 cleanly. This required a bump to the MMN. [Jeff Trawick]
2687 *) Add the socket back to the conn_rec and remove the create_connection
2688 hook. The create_connection hook had a design flaw that did not
2689 allow creating connections based on vhost info. [Bill Stoddard]
2691 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2692 Resolves the common case of using negotation to resolve the request
2693 /script/foo for /script.cgi/foo. [William Rowe]
2695 *) Added new functions ap_add_(input|output)_filter_handle to
2696 allow modules to bypass the usual filter name lookup when
2697 adding hard-coded filters to a request [Brian Pane]
2699 *) caching should now work on subrequests (still very experimental)
2702 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2704 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2707 *) Refactor ap_rgetline so that it does not use an internal brigade.
2708 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2710 *) Remove mod_auth_db. [Justin Erenkrantz]
2712 *) Do not install unnecessary pcre headers like config.h and internal.h.
2713 [Joe Orton <joe manyfish.co.uk>]
2715 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
2716 (as it does for a normal request). quick_handled sub-requests now work
2717 in mod-include [Ian Holsman]
2719 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
2720 'CONTENT' one, as it needs to run AFTER all content headers
2722 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
2725 *) Split out blocking from the mode in the input filters.
2728 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
2730 *) Cause Win32 to capture all child-worker process errors in
2731 Apache to the main server error log, until the child can
2732 open its own error logs. [William Rowe]
2734 *) HPUX 11.*: Do not kill the child process when accept()
2735 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
2736 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
2738 *) Fix a problem in the parsing of the <Proxy foo> directive.
2741 *) rewrite of mod_ssl input filter for better performance and less
2742 memory usage [Doug MacEachern]
2744 *) allow quick_handler to be run on subrequests. [Ian Holsman]
2746 *) mod_dav now asks its provider to place content directly into the
2747 filter stack when handling a GET request. The mod_dav/provider
2748 API has changed, so providers need to be updated. [Greg Stein]
2750 *) Clear the output socket descriptor in unixd_accept() to make sure
2751 we don't supply a bogus socket to the caller if the accept fails.
2752 This caused problems with the worker MPM, which tried to process
2753 the returned socket if it was non-NULL. [Brian Pane]
2755 *) Move a check for an empty brigade to the start of core input filter
2756 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
2758 *) Add FileETag directive to allow configurable control of what
2759 data are used to form ETag values for file-based URIs. MMN
2760 bumped to 20020111 because of fields added to the end of
2761 the core_dir_config structure. [Ken Coar]
2763 *) Fix a segfault in mod_rewrite's logging code caused by passing the
2764 wrong config to ap_get_remote_host(). [Jeff Trawick]
2766 *) Allow mod_cgid to work from a binary distribution install by
2767 using 755 for the permissions on the log directory instead of
2770 *) Fixed a segfault that happened during graceful shutdown (or when
2771 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
2773 *) Split all Win32 modules [excluding the core components mod_core,
2774 mod_so, mod_win32 and the winnt mpm] into individual loadable
2775 modules, so the administrator may individually disable the former
2776 compiled-in modules by simply commenting out their LoadModule
2777 directives. [William Rowe]
2779 *) Saved Win32 module authors and porters many future headaches, by
2780 duplicating the appropriate .h files such as os.h into the include
2781 directory, including in the build tree. [William Rowe]
2783 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
2784 Use SSL functions/macros instead of directly dereferencing SSL
2785 structures wherever possible.
2786 Add type-casts for the cases where functions return a generic pointer.
2787 Add $SSL/include to configure search path.
2788 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
2790 *) Moved several pointers out of the shared Scoreboard so it is
2791 more portable, and will present the vhost name across server
2792 generation restarts. [William Rowe]
2794 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
2797 Changes with Apache 2.0.30
2799 *) Fix the main bug for FreeBSD and threaded MPM's. There are
2800 still issues (see STATUS) but at least the server will now
2801 run without crashing the machine.
2802 [David Reid, Aaron Bannert, Justin Erenkrantz]
2804 *) Fix a typo in mod_deflate's m4 config section.
2805 [albert chin <china thewrittenword.com>]
2807 *) Fix a couple of mod_proxy problems forwarding HTTP connections
2808 and handling CONNECT:
2809 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
2810 (2) Proxy failed to connect when the first IP address returned by
2811 the resolver was unreachable but a secondary IP address was.
2814 *) Fix the module identifer as shown in the docs for various core
2815 modules (e.g., the identifer for mod_log_config was previously
2816 listed as config_log_module). PR #9338
2817 [James Watson <ap2bug sowega.org>]
2819 *) Fix LimitRequestBody directive by placing it in the HTTP
2820 filter. [Justin Erenkrantz]
2822 *) Fix mod_proxy seg fault when the proxied server returns
2823 an HTTP/0.9 response or a bogus status line.
2826 *) Prevent mod_proxy from truncating one character off the
2827 end of the status line returned from the proxied server.
2828 [Adam Sussman, Bill Stoddard]
2830 *) Eliminate loop in ap_proxy_string_read().
2831 [Adam Sussman, Bill Stoddard]
2833 *) Provide $0..$9 results from mod_include regex parsing.
2836 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
2838 *) Introduced the ForceLanguagePriority directive, to prevent
2839 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
2840 when using Multiviews. [William Rowe]
2842 *) Fix a problem which prevented mod_cgid and suexec from working
2843 together reliably [Greg Ames]
2845 *) Remove the call to exit() from within mod_auth_digest's post_config
2846 phase. [Aaron Bannert]
2848 *) Fix a problem in mod_auth_digest that could potentially cause
2849 problems with initialized static data on a system that uses DSOs.
2852 *) Fix a segfault in the worker MPM that could happen during
2853 child process exits. [Brian Pane, Aaron Bannert]
2855 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
2857 *) Fix matching of vhosts by ip address so we find IPv4
2858 vhost address when target address is v4-mapped form of
2859 that address. [Jeff Trawick]
2861 *) More performance tweaks to the BNDM string-search algorithm
2862 used to find "<!--#" tokens in mod_include [Brian Pane]
2864 *) Miscellaneous small performance fixes: optimized away various
2865 string copy operations and removed large temp buffers from
2866 the stack [Brian Pane]
2868 *) Fixed startup segfault that occurred when a VirtualHost
2869 directive had a port but no address [Brian Pane]
2871 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
2873 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
2874 if oslevel < WINNT. This should fix several problems reported
2875 Against 2.0.28 on Windows 98 [Bill Stoddard]
2877 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
2878 to fail. [Bill Stoddard]
2880 *) Change core code to allow an MPM to set hard thread/server
2881 limits at startup. prefork, worker, and perchild MPMs now have
2882 directives to set these limits. [Jeff Trawick]
2884 *) Win32: The async AcceptEx() event should be autoreset upon
2885 successful completion of a wait (WaitForSingleObject). This
2886 eliminates a number of spurious
2887 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
2890 *) Move any load library path environment variables out of
2891 apachectl and into a separate environment variable file which
2892 can be more easily tailored by the admin. The environment
2893 variable file as built by Apache may have additional system-
2894 specific settings. For example, on OS/390 we tailor the heap
2895 settings to allow lots of threads. [Jeff Trawick]
2897 *) Use the new APR pool code to reduce pool-related lock
2898 contention in the worker MPM. [Sander Striker]
2900 *) The POD no longer assumes the child is listening on 127.0.0.1
2901 and now pulls the first hostname in the list of listeners to
2902 perform the dummy connect on. This fixes a bug when the user
2903 had configured the Listen directive for an IP other than
2904 127.0.0.1. This would result in undead children and error
2905 messages such as "Connection refused: connect to listener".
2908 *) The worker MPM now respects the LockFile setting, needed to
2909 avoid locking problems with NFS. [Jeff Trawick]
2911 *) Fix segfault when worker MPM receives SIGHUP.
2912 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
2914 *) Fix bug that could potentially prevent the perchild MPM from
2915 working with more than one vhost/uid. [Aaron Bannert]
2917 *) Change make install and apxs -i processing of DSO modules to
2918 perform special handling on platforms where libtool doesn't install
2919 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
2920 which prevented standard LoadModule statements from working.
2923 *) Whenever mod_so is enabled (not just when there are DSOs for
2924 our modules), do whatever special magic is required for compiling/
2925 loading third-party modules. This allows third-party DSOs to
2926 be used on an AIX build when there were no built-in modules
2927 built as DSOs. (This should help on OS/390 and BeOS as well.)
2930 *) Allow apxs to be used to build DSOs on AIX without requiring the
2931 user to hard-code the list of import files. (This should help
2932 on OS/390 and BeOS as well.) [Jeff Trawick]
2934 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
2935 PR 8563, 8919 [William Rowe]
2937 *) Get binary builds working when libapr and libaprutil are built
2940 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
2941 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
2942 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
2944 *) Fix the handling of SSI directives in which the ">" of the
2945 terminating "-->" is the last byte in a file [Brian Pane]
2947 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
2948 message that we had back in apache-1.3 and still have scattered
2949 throughout our docs. [Aaron Bannert]
2951 *) Prevent the Win32 port from continuing after encountering an
2952 error in the command line args to apache. [William Rowe]
2954 *) On a error in the proxy, make it write a line to the error log
2957 *) Various mod_ssl performance improvements [Doug MacEachern]
2959 Changes with Apache 2.0.29
2961 *) Add buffering in core_output_filter to ensure that long
2962 lists of small buckets don't cause small packet writes.
2963 [Brian Pane, Ryan Bloom]
2965 *) Fix the installation target to make sure that the manual is
2966 installed in the correct location.
2967 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
2968 Gomez Henri <hgomez slib.fr>]
2970 *) Fix the cmd command for mod_include. When we are processing
2971 a cmd command, we do not want to use the r->filename to set
2972 the command name. The command comes from the SSI tag. To do this,
2973 I added a variable to the function that builds the command line
2974 in mod_cgi. This allows the include_cmd function to specify
2975 the command line itself. [Ryan Bloom]
2977 *) Change open_logs hook to return a value, allowing you
2978 to flag a error while opening logs
2979 [Ian Holsman, Doug MacEachern]
2981 *) Change post_config hook to return a value, allowing you
2982 to flag a error post config
2983 [Ian Holsman, Jeff Trawick]
2985 *) Allow SUEXEC_BIN (the path to the suexec binary that is
2986 hard-coded into the server) to be specified to the configure
2987 script by the --with-suexec-bin parameter. [Aaron Bannert]
2989 *) Fix segv in worker MPM following accept on pipe-of-death
2992 *) Add mod_deflate to experimental.
2993 [Ian Holsman, Justin Erenkrantz]
2995 *) Bail out at configure time if an invalid MPM was specified.
2996 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
2998 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
2999 configured [John Sterling <sterling covalent.net>]
3001 *) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>]
3003 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
3005 *) Optimization for the BNDM string-search function in
3006 mod_include. [Brian Pane]
3008 *) Fixed the behavior of the XBitHack directive.
3009 [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
3011 *) The threaded MPM for Unix has been removed. Use the worker
3012 MPM instead. [various]
3014 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
3015 in logging the error from a failed DNS lookup. [Jeff Trawick]
3017 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
3020 *) Get mod_cgid killed when a MPM exits due to a fatal error.
3023 *) Fix a file descriptor leak in mod_include. When we include a
3024 file, we use a sub-request, but we didn't destroy the sub-request
3025 immediately, instead we waited until the original request was
3026 done. This patch closes the sub-request as soon as the data is
3027 done being generated. [Brian Pane <bpane pacbell.net>]
3029 *) Allow modules that add sockets to the ap_listeners list to
3030 define the function that should be used to accept on that
3031 socket. Each MPM can define their own function to use for
3032 the accept function with the MPM_ACCEPT_FUNC macro. This
3033 also abstracts out all of the Unix accept error handling
3034 logic, which has become out of synch across Unix MPMs.
3037 *) Fix a bug which would cause the response headers to be omitted
3038 when sending a negotiated ErrorDocument because the required
3039 filters were attached to the wrong request_rec.
3040 [John Sterling <sterling covalent.net>]
3042 *) Remove commas from the end of the macros that define
3043 directives that are used by MPMs. Prior to this patch,
3044 you would use these macros without commas, which was unlike
3045 the macros for any other directives. Now, the caller provides
3046 the comma rather than the macro providing it. This makes
3047 the macros look more like the rest of the directives.
3048 [Ryan Bloom and Cliff Woolley]
3050 *) Add 'redirect-carefully' environment option to disable sending
3051 redirects under special circumstances. This is helpful for
3052 Microsoft's WebFolders when accessing a directory resource via
3053 DAV methods. [Justin Erenkrantz]
3055 *) Begin to abstract out the underlying transport layer.
3056 The first step is to remove the socket from the conn_rec,
3057 the server now lives in a context that is passed to the
3058 core's input and output filters. This forces us to be very
3059 careful when adding calls that use the socket directly,
3060 because the socket isn't available in most locations.
3063 *) Really reset the MaxClients value in worker and threaded
3064 when the configured value is not a multiple of the number
3065 of threads per child. We said we did previously but we
3066 forgot to. [Jeff Trawick]
3068 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
3070 *) If shared modules are requested and mod_so is not available,
3071 produce a fatal config-time error. [Justin Erenkrantz]
3073 *) Improve http2env's performance by cutting the work it has to
3074 do. [Brian Pane <bpane pacbell.net>]
3076 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
3077 [Brian Pane <bpane pacbell.net>]
3079 Changes with Apache 2.0.28
3081 *) Fix infinite loop in mod_cgid.c.
3082 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
3084 *) When no port is given in a "ServerName host" directive, the
3085 server_rec->port is now set to zero, not 80. That allows for
3086 run-time deduction of the correct server port (depending on
3087 SSL/plain, and depending also on the current setting of
3088 UseCanonicalName). This change makes redirections
3089 work, even with https:// connections. As in Apache-1.3, the
3090 connection's actual port number is never used, only the ServerName
3091 setting or the client's Host: setting. Documentation updated
3092 to reflect the change. [Martin Kraemer]
3094 *) Add a '%{note-name}e' argument to mod-headers, which works in
3095 the same way as mod_log_confg. [Ian Holsman]
3097 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
3098 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
3099 MPMs. [Cliff Woolley]
3101 *) Introduce htdbm, a user management utility for db/dbm authorization
3102 databases. [Mladen Turk <mturk mappingsoft.com>]
3104 *) Optimize usage of strlen and strcat in ap_directory_walk.
3105 [Brian Pane <bpane pacbell.net>]
3107 Changes with Apache 2.0.27
3109 *) Introduce an Apache mod_ssl initial configuration template
3110 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
3112 *) Fixed a memory leak in the getline parsing code that could
3113 be triggered by arbitrarily large header lines. Requests
3114 from the core input filter for single lines are now limited
3115 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
3117 *) Fix a truncation bug in how we print the port on the Via: header.
3118 The routine that prints the Via: header now takes a length for
3119 the port string. [Zvi Har'El <rl math.technion.ac.il>]
3121 *) Some syntax errors in mod_mime_magic's magic file can result
3122 in a 500 error, which previously was unlogged. Now we log the
3123 error. [Jeff Trawick]
3125 *) Add the support/checkgid helper app, which checks the run-time
3126 validity of group identifiers usable in the Group directive.
3129 *) Various --enable-so options have been fixed: --enable-so is
3130 treated as "static"; explicit --enable-so=shared issues an error;
3131 and explicit --enable-so fails with error on systems without
3132 APR_HAS_DSO. [Aaron Bannert]
3134 *) Fix a segfault in the core input filter when the client socket
3135 gets disconnected unexpectedly. [Cliff Woolley]
3137 *) Fix the reporting for child processes that die. This removes
3138 all of the non-portable W* macros from Apache.
3139 [Jeff Trawick and Ryan Bloom]
3141 *) Win32: Track and display "Parent Server Generation:" in
3142 mod_status output. The generation will be bumped at
3143 server graceful restart, when the child process exits
3144 by hitting MaxRequestsPerChild or if the child
3145 process exits abnormally. [Bill Stoddard]
3147 *) Win32: Fix problem where MaxRequestsPerChild directive was
3148 not being picked up in favor of the default. Enable
3149 the parent to start up a new child process immediately upon
3150 the old child starting shutdown.
3153 *) Fix some bungling of the remote port in rfc1413.c so that
3154 IdentityCheck retrieves the proper user id instead of failing
3155 and thus always returning "nobody."
3156 [Dick Streefland <Dick.Streefland xs4all.nl>]
3158 *) Introduced thread saftey for mod_rewrite's internal cache.
3159 [Brian Pane <bpane pacbell.net>]
3161 *) Simplified mod_env's directives to behave as most directives are
3162 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
3163 directive following that UnsetEnv within the same container.
3164 Also provides a runtime startup warning if a PassEnv configured
3165 environment value is undefined. [William Rowe]
3167 *) The worker MPM is now completely ported to APR's new lock API. It
3168 uses native APR types for thread mutexes, cross-process mutexes,
3169 and condition variables. [Aaron Bannert]
3171 *) Sync up documentation to remove all references to the now deprecated
3172 Port directive. [Justin Erenkrantz]
3174 *) Moved all ldap modules from the core to httpd-ldap sub-project
3177 *) Exit when we can't listen on any of the configured ports. This
3178 is the same behavior as 1.3, and it avoids having the MPMs to
3179 deal with bogus ap_listen_rec structures. [Jeff Trawick]
3181 *) Cleanup the proxy code that creates a request to the origin
3182 server. This change adds an optional hook, which allows modules
3183 to gain control while the request is created if the proxy module
3184 is loaded. The purpose of this hook is to allow modules to add
3185 input and/or output filters to the request to the origin. While
3186 I was at it, I made the core use this hook, so that proxy request
3187 creation uses some of the code from the core. This can still be
3188 greatly improved, but this is a good start. [Ryan Bloom]
3190 Changes with Apache 2.0.26
3192 *) Port the MaxClients changes from the worker MPM to the threaded
3195 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
3196 with the new input filtering system. [Justin Erenkrantz]
3198 *) Introduce the MultiviewsMatch directive, to allow the operator
3199 to be flexible in recognizing Handlers and Filters filename
3200 extensions as part of the Multiviews matching logic, strict with
3201 MultiviewsMatch NegotiatedOnly to accept only filename extentions
3202 that designate negotiated parameters, (content type, charset, etc.)
3203 or MultiviewsAll for the 1.3 behavior of matching any files, even
3204 if they have unregistered extensions. [William Rowe]
3206 *) Fixed the configure script to add a LoadModule directive to
3207 the default httpd.conf for any module that was compiled
3208 as a DSO. [Aaron Bannert <aaron clove.org>]
3210 *) rewrite mod_ssl input filtering to work with the new input filtering
3211 system. [Justin Erenkrantz]
3213 *) prefork: Don't segfault when we are able to listen on some but
3214 not all of the configured ports. [Jeff Trawick]
3216 *) Build mod_so even if no core modules are built shared.
3217 [Aaron Bannert <aaron clove.org>]
3219 *) Introduce ap_directory_walk rewrite (with further optimizations
3220 required) to adapt to the ap_process_request_internal() changes.
3221 Optimized so subrequests and redirects now reuse previous section
3222 merges, until we mismatch with the original directory_walk, and
3223 precomputed r->finfo results will cause directory_walk to skip
3224 the most expensive phases of the function. [William Rowe]
3226 *) Allow ApacheMonitor to connect to and control Apache on other
3227 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
3229 *) Remove the Port directive. In it's place, the Listen directive
3230 is now a required directive, which tells Apache what port to
3231 listen on. The ServerName directive has also been extended
3232 to accept an optional port. If the port is specified to the
3233 ServerName, the server will report that port whenever it
3234 reports the port that it is listening on. This change was
3235 made to ease configuration errors that stem from having a Port
3236 directive, and a Listen directive. In that situation, the server
3237 would only listen to the port specified by the Listen command,
3238 which caused a lot of confusion to users. [Ryan Bloom]
3240 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
3241 build, as loadable modules. [William Rowe]
3243 *) Fix --enable-mods-shared processing. If most is specified,
3244 then all modules that can be compiled as shared modules are.
3245 [Aaron Bannert <aaron clove.org>]
3247 *) Update the mime.types file to map video/vnd.mpegurl to mxu
3248 and add commonly used audio/x-mpegurl for m3u extensions.
3249 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
3251 *) Eliminate the depreciated r->content_language, in favor of the array
3252 r->content_languages introduced many years ago. Module authors must
3253 substantially overhaul their modules, so this needs to be upgraded
3254 if the module still relied on backwards-brokeness. [William Rowe]
3256 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
3259 *) Rewrite the input filtering mechanisms to consolidate and reorganize
3260 code. In short, core_input_filter does something now and
3261 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
3263 *) Update the Win32 build to re-absorb mod_proxy and family.
3266 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
3267 current SDK.) [William Rowe]
3269 *) Some style changes to the code that does ProxyErrorOverride. Fixed
3270 config merge behaviour. [Graham Leggett]
3272 *) Allow support programs to be compiled against a static version
3273 of libapr. This allows the smaller support programs to be
3274 relocated. [Aaron Bannert <aaron clove.org>]
3276 *) Update the mime.types file to the registered media types as
3277 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
3279 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
3280 number of clients that can connect at the same time, instead of
3281 specifying the maximum number of child processes.
3282 [Aaron Bannert <aaron clove.org>]
3284 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
3285 be consistent with 1.3. [Justin Erenkrantz]
3287 *) Cache apr_explode_localtime() value for 15 seconds.
3288 [Brian Pane <bpane pacbell.net>]
3290 *) Fix mod_include to not return ETag or Last-Modified headers.
3291 [Ian Holsman <ianh cnet.com>]
3293 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
3295 *) Eliminate the wasteful run-time conversion of method names from strings
3296 to numbers in places where the methods are known at compile time.
3297 [Brian Pane <bpane pacbell.net>]
3299 *) Turn the worker MPM's queue into a LIFO. This may
3300 improve cache-hit performance under some conditions.
3301 [Aaron Bannert <aaron clove.org>]
3303 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
3304 support it. [Justin Erenkrantz]
3306 *) Cleanup the worker MPM. We no longer re-use transaction
3307 pools. This incurs less overhead than shuffling the pools
3308 around so that they can be re-used. Remove one of the
3309 queue's condition variables. We just redefined the API to
3310 state that you can't try to add more stuff than you allocated
3311 segments for. [Aaron Bannert <aaron clove.org>]
3313 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
3315 *) Fixed persistent connections when a request contains a body.
3318 *) mod_dav uses a new API to speak to the backend provider for dead
3319 property management. [Greg Stein]
3321 *) Remove the Win32 script-processing exception from mod_cgi, and
3322 roll build_command_line/build_argv_list into a unified, overrideable
3323 ap_cgi_build_command optional function. [William Rowe]
3325 *) Rewrite find_start_sequence to use a better search algorithm
3326 to find the start tag. [Justin Erenkrantz]
3328 *) Fix a seg fault in mod_include. When we are generating an
3329 internal redirect, we must set r->uri to "", not a bogus
3330 string, and not NULL. [Ryan Bloom]
3332 *) Optimized location_walk, so subrequests, redirects and second passes
3333 now reuse previous section merges on a <Location > by <Location >
3334 basis, until we mismatch with the original location_walk.
3337 *) Back out the 1.45 change to util_script.c. This change made
3338 us set the environment variable REQUEST_URI to the redirected
3339 URI, instead of the originally requested URI.
3340 [Taketo Kabe <kabe sra-tohoku.co.jp>]
3342 *) Make mod_include do lazy evaluation of potentially expensive to
3343 compute variables. [Brian Pane <bpane pacbell.net>]
3345 *) Fix logging of bytes sent for HEAD requests. %b and %B should
3346 log either - or 0, before this patch, they were both logging
3347 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
3349 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
3350 than per character. [Brian Pane <bpane pacbell.net>]
3352 *) Normalize the primary request, redirects and sub-requests to
3353 run the same ap_process_request_internal for consistency in
3354 robustness, behavior and security. [William Rowe]
3356 *) Fix a segfault with mod_include when r->path_info is not set
3357 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
3359 *) Add -X functionality back. This indicates to all MPMs and any other
3360 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
3362 *) Some initial support for the cygwin platform [prefork only].
3363 This is not to be confused with support for the WinNT/Win32
3364 platform, which is the recommended configuration for native
3365 Win32 users. The cygwin platform support is recommended for
3366 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
3368 *) Changed syntax of Set{Input|Output}Filter. The list of filters
3369 must be semicolon delimited (if more than one filter is given.)
3370 The Set{Input|Output}Filter directive now overrides a parent
3371 container's directive (e.g. SetInputFilter in <Directory /web/foo>
3372 will override any SetInputFilter directive in <Directory /web>.)
3373 This new syntax is more consistent with Add{Input|Output}Filter
3374 directives defined in mod_mime. Also cures a bug in prior releases
3375 where the Set{Input|Output}Filter directive would corrupt the
3376 global configuration if the multiple directives were nested.
3379 *) Cured what's ailed mime for quite some time. If an AddSomething
3380 was given in the configuration (Language, Charset, Handler or
3381 Encoding) Apache would set the content type as given by AddType,
3382 but refused to check the mime.types file if AddType wasn't given
3383 for that specific extension. Setting the AddHandler for .html
3384 without setting the AddType text/html html would cause Apache to
3385 use the default content type. [William Rowe]
3387 *) Added some bulletproofing to memory allocation in the LDAP cache
3388 code. [Graham Leggett]
3390 Changes with Apache 2.0.25
3392 *) Move the installed /manual directory out of the /htdocs/ tree, so
3393 that it can be kept more independently from the remaining document
3394 root. The "Alias /manual ..." already allowed for easy projection
3395 into existing private document trees. [Martin Kraemer]
3397 *) Add specified user attributes to the environment when using
3398 mod_auth_ldap. This allows you to use mod_include to embed specified
3399 user attributes in a page like so:
3400 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
3403 *) Fix a performance problem with the worker MPM. We now create
3404 transaction pools once, and re-use them for each connection.
3405 [Aaron Bannert <aaron clove.org>]
3407 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
3408 of a 'handler' or 'filter', so that any filename extension that does
3409 not contribute to the negotiated metadata can't be served without
3410 an explicit request. E.g., if the .Z extension is associated with
3411 an unzip filter, the user request somefile.Z.html, mod_negotiation
3412 won't serve it. It can serve somefile.Z.html when somefile.Z is
3413 requested, since the .Z extension is explictly requested, if the
3414 .html extension is associated with ContentType text/html.
3417 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
3418 and corresponding AddOutputFilter syntax, to insert one or more
3419 filters by mod_mime filename extension processing.
3422 *) Fix a growing connection pool in core_output_filter() for
3423 keepalive requests. [Jeff Trawick]
3425 *) Moved split_and_pass_pretag_buckets back to being a
3426 macro at Ryans's request. Removed the return from it
3427 by setting and returning a return code instead. Updated
3428 the code to check the return code from the macro and
3429 do the right thing. [Paul J. Reder]
3431 *) Fix a segfault when a numeric value was received for Host:.
3434 *) Add a function ap_remove_input_filter. This is to match
3435 up with ap_remove_output_filter. [Ryan Bloom]
3437 *) Clean up location_walk, so that this step performs a minimum
3438 amount of redundant effort (it must be run twice, but it will no
3439 longer reparse all <Location > blocks when the request uri
3440 hadn't changed.) [William Rowe]
3442 *) Eliminate proxy: (and all other 'special') processing from the
3443 ap_directory_walk() phase. Modules that want to use special
3444 walk logic should refer to the mod_proxy map_to_location example,
3445 with it's proxy_walk and proxysection implementation. This makes
3446 either directory_walk flavor much more legible, since that phase
3447 only runs against real <Directory > blocks.
3450 *) SECURITY: Fix a security problem in mod_include which would allow
3451 an SSI document to be passed to the client unparsed.
3452 [Cliff Woolley, Brian Pane]
3454 *) Introduce the map_to_storage hook, which allows modules to bypass
3455 the directory_walk and file_walk for non-file requests. TRACE
3456 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
3457 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
3460 *) Add the ability for mod_include to add the INCLUDES filter
3461 if the file is configured for the server-parsed handler.
3462 This makes the configuration for .shtml files much easier
3463 to understand, and allows mod_include to honor Apache 1.3
3464 config files. Based on Doug MacEachern's patch to PHP
3465 to do the same thing. [Ryan Bloom]
3467 *) force OpenSSL to ignore process local-caching and to always
3468 get/set/delete sessions using mod_ssl's callbacks
3469 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3470 Geoff Thorpe <geoff geoffthorpe.net>]
3472 *) Make the worker MPM shutdown and restart cleanly. This also
3473 cleans up some race conditions, and gets the worker using
3474 pools more cleanly. [Aaron Bannert <aaron clove.org>]
3476 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
3478 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3480 *) Fix for mod_include. Ryan's patch to check error
3481 codes put a return in the wrong place. Also, the
3482 include handler return code wasn't being checked.
3483 I don't like macros with returns, so I converted
3484 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
3485 [Paul J. Reder <rederpj raleigh.ibm.com>]
3487 *) fix segv in mod_mime if no AddTypes are configured
3488 [John Sterling <sterling covalent.net>]
3490 *) Enable ssl client authentication at SSL_accept time
3491 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3493 *) Fix a segfault in mod_include when the original request has no
3494 associated filename (e.g., we're filtering the error document for
3495 a bad URI). [Jeff Trawick]
3497 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
3499 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
3500 of httpd is started and shuts down due to socket conflict. Moving the
3501 call to ap_log_pid solves the problem.
3503 *) Changed the late-1.3 log_config substitution %c to %X, to log the
3504 status of the closed connection, as it conflicts with the far more
3505 common, historical ssl logging directive %...{var}c. [William Rowe]
3507 *) Added the common error/ tree to the build/install targets
3508 (similar to the common icons/ tree) for the multi-language error
3509 messages that Lars committed earlier. [William Rowe]
3511 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
3513 *) Added a default commented-out mod_ldap and mod_auth_ldap
3514 configuration to httpd-std.conf and httpd-win.conf
3517 *) Added documentation for mod_ldap and mod_auth_ldap.
3520 *) Enabled negative caching on attribute comparisons in the LDAP cache.
3521 Fixed a problem where the default cache TTL was set in milliseconds
3522 not microseconds causing the cache to time out almost immediately.
3525 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
3526 module code to follow APR. [Graham Leggett]
3528 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
3529 cleaned up when the connection pool pool is cleaned up.
3532 *) Fix a minor issue with Jeff Trawick's mod_include
3533 patch. Without this patch, the code will just allocate
3534 more bytes in get_combined_directive than are needed.
3537 *) Added the LDAP authentication module mod_auth_ldap.
3538 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3540 *) Added the LDAP cache and connection pooling module mod_ldap.
3541 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3543 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
3544 by allowing a module to disable itself if its prerequisites are not
3545 met. [Justin Erenkrantz]
3547 Changes with Apache 2.0.24
3549 *) Fix a couple of issues in mod_include when the tag appeared at
3550 offsets near 8192 in the file being parsed. [Jeff Trawick]
3552 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
3553 reached. [Jeff Trawick]
3555 *) Numerous improvements to the Win32 build system. Introduced command line
3556 builds without requiring .mak files for MSVC 6.0 and later versions.
3557 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
3560 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
3561 reporting of uninstalled services and other error conditions, and changed the
3562 default service name to Apache2. [William Rowe]
3564 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
3565 compatibility with existing Apache 1.3 Win32 Apache management utilites.
3566 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
3568 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
3569 [William Rowe, Greg Ames]
3571 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
3572 and RemoveCharset directives. [William Rowe]
3574 *) The Unix MPMs other than perchild now allow child server
3575 processes to use the accept mutex when starting as root and
3576 using SysV sems for the accept mutex. Previously, this
3577 combination would lead to fatal errors in the child server
3578 processes. perchild can't use SysV sems because of security
3579 issues. [Jeff Trawick, Greg Ames]
3581 *) Added Win32 revision stamp resources to all http binaries
3582 (including modules/ and support/ tools.) PR7322 [William Rowe]
3584 *) Fix ap_rvprintf to support more than 4K of data at one time.
3585 [Cody Sherr <csherr covalent.net>]
3587 *) We have always used the obsolete/deprecated Netscape syntax
3588 for our tracking cookies; now the CookieStyle directive
3589 allows the Webmaster to choose the Netscape, RFC2109, or
3590 RFC2965 format. The new CookieDomain directive allows the
3591 setting of the cookie's Domain= attribute, too. PR #s 5006,
3592 5023, 5920, 6140 [Ken Coar]
3594 *) Tweak server/Makefile so that the rules for generating exports.c
3595 are compatible with make utilities which don't expand wildcards
3596 in a dependency list (e.g., OS/390 make, certain levels of GNU
3597 make). [Jeff Trawick]
3599 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
3601 *) Begin to sanitize the MPM configuration directives. Now, all
3602 MPMs use the same functions for all common MPM directives. This
3603 should make it easier to catch all bugs in these directives once.
3604 [Cody Sherr <csherr covalent.net>]
3606 *) Close a major resource leak. Every time we had issued a
3607 graceful restart, we leaked a socket descriptor.
3610 *) Fix a problem with the new method code. We need to cast
3611 the 1 to an apr_int64_t or it will be treated as a 32-bit
3612 integer, and it will wrap after being shifted 32 times.
3613 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
3615 *) Fix a bug in mod_expires. Previous to this patch, if you
3616 told mod_expires to add 604800 seconds to the last-modified
3617 time, it actually added 604800 usec's to the last-modified time,
3618 so that when looking at the response it looked like nothing
3619 had been done. The root of the problem was that we always compute
3620 time in usec's, but we ask users to input sec's. This means we
3621 need to convert to usec's before using those values.
3624 *) The worker MPM now handles shutdown and restart requests. It
3625 definitely isn't perfect, but we do stop the servers correctly.
3626 The biggest problem right now is that SIGHUP causes the server to
3627 just die. [Ryan Bloom]
3629 Changes with Apache 2.0.23
3631 *) Use the prefork MPM by default on Unix. [various]
3633 *) Added a systray icon monitor application for Win32.
3634 [Mladen Turk <mturk mappingsoft.com>]
3636 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3637 messages written to the rewrite log.
3638 [Richard Labennett <rlabenn us.ibm.com>]
3640 *) All mod_autoindex query parsing is now quietly quashed with the
3641 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3642 still drops the column sort <a href>'s for the column headers, but
3643 IgnoreClient is required to ignore these Query options entirely.
3646 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3647 to allow the client to select plain, FancyIndexing or HTMLTable
3648 formatting, V=[0|1] to inhibit or enable version sorting, and
3649 P=pattern to return only specific files. The old Query Arguments
3650 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3651 as before), and O=A|D for ordering ascending or descending.
3654 *) Fixed an error in mod_include's directive parsing routines which
3655 caused #if, #elif, and #else expressions containing backslashes
3656 to be improperly evaluated. [Cliff Woolley]
3658 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3659 drop the icon column, SuppressRules to drop the <hr> elements,
3660 and HTMLTable to create rudimentary HTML table listings (implies
3661 FancyIndexing). [William Rowe]
3663 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3664 from Apache 1.3.15. This is needed for two reasons, first, given
3665 multiple machines within a server farm, ETags and Last-Modified
3666 stamps won't correspond from machine to machine, and second, many
3667 Unixes don't capture changes to the date or time stamp of existing
3668 files, since these don't modify the dirent itself. [William Rowe]
3670 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3671 and DirectoryWidth options from Apache 1.3.10.
3672 [William Rowe, Ken Coar]
3674 *) Eliminated FancyIndexing directive, deprecated early in Apache
3675 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3677 *) mod_autoindex now excludes any file names that would result in
3678 an error, other than a success or redirect. Also optimized
3679 the parent directory, always included except in the URI '/'.
3682 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3683 negotiated index pages, and prevent the server from defaulting
3684 to an autoindex of the directory. mod_negotiation will now die
3685 with a 500 Internal Error if it could match some filenames
3686 (e.g. for mod_dir) but none can be served. mod_negotation now
3687 refuses to serve any file with an extention that mod_mime doesn't
3688 recognize, and wasn't part of the request. [William Rowe]
3690 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3691 extension. This is already handled by multiviews, if the admin
3692 wishes to AddHandler .exe or define a content type handler and
3693 associate .exe files with that content type. Multiviews must be
3694 enabled to allow these to be served. [William Rowe]
3696 *) Speed up the server's response to a spike in incoming workload
3697 or restarts by assigning empty scoreboard slots to new processes
3698 when they are available. [Greg Ames]
3700 *) Add a handler to mod_includes.c. This handler is designed to
3701 implement the XbitHack directive. This can't be done with a
3702 fixup, because we need to check the content-type, which is
3703 only available in the handler phase. [Ryan Bloom]
3705 *) Make the includes filter check return codes from filters lower in
3706 the filter chain. If a lower level filter returns an error, then
3707 the request needs to stop immediately. This allows mod_include to
3708 stop parsing data once a lower filter recognizes an error.
3711 *) Add the ability to extend the methods that Apache understands
3712 and have those methods <limit>able in the httpd.conf. It uses
3713 the same bit mask/shifted offset as the original HTTP methods
3714 such as M_GET or M_POST, but expands the total bits from an int to
3715 an ap_int64_t to handle more bits for new request methods than
3716 an int provides. [Cody Sherr <csherr covalent.net>]
3718 *) Fix broken mod_mime behavior in merging its arguments. Possible
3719 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
3721 *) Solve many mod_ssl porting issues (too many to detail) with
3722 help from the whole team, but most notably [Ralf S. Engelschall,
3723 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3724 Doug MacEachern, William Rowe, Cliff Woolley]
3726 *) More stall fixes for the threaded & worker mpm's.
3727 Make mod_status output more accurate. Don't
3728 count workers in processes which aren't actively
3729 serving requests. [Greg Ames]
3731 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
3733 *) Add a single listener/multiple worker MPM. This MPM is
3734 definately not fully correct, but it allows us to solve many
3735 of the problems that exist in the threaded MPM. This is a
3736 modified version of the threaded MPM. [Ryan Bloom]
3738 *) Improve content generation throughout Apache, providing closer
3739 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
3740 Transitional specifications. [William Rowe]
3742 Changes with Apache 2.0.22
3744 *) Fix a problem where the threaded MPM stalls after restarts or
3745 segfaults. Also prevent multiple active processes from using
3746 the same scoreboard slot. [Greg Ames]
3748 *) Apache/Win32 now fills in the service description with Apache's
3749 server version string, including loaded and advertised modules.
3752 *) Improved support for the Win32 build, to recover gracefully from
3753 missing apr or apr-util directories or the awk interpreter,
3754 create the proper cgi-bin examples, including a test-cgi.bat, and
3755 fix the perl shebang line for printenv.pl, when installing from
3756 the build environment. [William Rowe]
3758 *) Fix a segfault in threaded.c caused by passing uninitialized
3759 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
3761 *) Use new APR number conversion functions to reduce CPU consumption
3762 when setting the content length, and in mod_log_config.
3765 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
3766 where HEAD response headers were being repeated twice for
3767 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
3768 problem in the http_header filter was exposed by the recent rewrite
3769 of the content_length filter. [Taketo Kabe, Bill Stoddard]
3771 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
3772 restarts. A garbage pointer to a vhost's server_rec from the
3773 previous generation was being left around under certain
3774 conditions. [Greg Ames]
3776 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
3777 used to appear as '(none', without the closing paren.
3778 [Günter Knauf <eflash gmx.net>]
3780 *) Improve the exports generating awk script. In the past, we had
3781 work around problems in the awk script by avoiding some #if and
3782 #ifdefs. This has bitten us many times in generating the exports.c
3783 file. This improvement allows corrects the header file parsing.
3784 [Sander Striker <striker apache.org>]
3786 Changes with Apache 2.0.21
3788 *) Resolve the Win32 htpasswd bug, where a file that existed would be
3789 overwritten, regardless of the -c flag.
3790 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
3792 *) Introduce connection sub-pools into ab. Truncating the lifetime
3793 of these allocations means that ab no longer perpetually grows
3794 its working set, running out of memory on large request attempts.
3797 *) Make scoreboard creation a hook. This allows management
3798 modules to have access to the scoreboard at the time that it is
3799 created, and at every restart request.
3800 [Cody Sherr <csherr covalent.net>]
3802 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
3803 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
3804 daemon index actually used in the scoreboard. I also
3805 updated the pertinent calls. [Paul J. Reder]
3807 *) Win32: Prevent listening sockets from being inherited by
3808 the Apache child process, CGI scripts, rotatelog process
3809 etc. If the Apache child process segfaults, any processes
3810 that the child started are not reaped. Prior to this fix,
3811 these processes inherited the listening sockets which sometimes
3812 prevented the restarted Apache child process from accepting
3813 connections (ie, the server would hang).
3816 *) Provide vhost and request strings when ExtendedStatus is on.
3819 *) Fix some issues with the pod and prefork: check the pod *after*
3820 processing a connection so that a server processing a time-
3821 consuming request bails out as soon as practical; when the
3822 parent process wakes up a server process via connect(), use an
3823 APR timeout on the connect() so that we don't hang for a long
3824 time if there aren't server processes around to do accept().
3825 [Jeff Trawick, Greg Ames]
3827 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
3828 spends a lot of time in apr_table_get calls. Using the default
3829 httpd.conf, the tables for languages and charsets are somewhat
3830 large, so the time spent scanning them on each request is
3831 significant. Replacing the tables with hash tables provides
3832 a nice speedup. [Brian Pane <bpane pacbell.net>]
3834 *) Add two functions to allow modules to access random parts of the
3835 scoreboard. This allows modules compiled for one MPM to access the
3836 scoreboard, even if it the server was compiled for another MPM.
3837 [Harrie Hazewinkel <harrie covalent.net>]
3839 Changes with Apache 2.0.20
3841 *) Fix problem in content-length filter where the filter would
3842 buffer all the output from a CGI before sending any bytes
3843 down the filter stack to the network. This problem would cause
3844 significant memory consumption if the CGIs generated
3845 lots of bytes. [Bill Stoddard]
3847 *) Get non-blocking CGI pipe reads working with the bucket brigades.
3850 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
3853 *) Fix a bug in the threaded MPM that would cause it to kill off all
3854 workers immediately after starting if the number of workers started
3855 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
3857 Changes with Apache 2.0.19
3859 *) Fix problem with threaded MPM. The problem was that if each child
3860 process was busy serving a single long-lived request and the server
3861 was sent a graceful restart signal, the server would stop serving
3862 requests. This would happen because each child process would wait to
3863 die until the last thread was done, and the parent wouldn't spawn any
3864 new children until a process died. Now, the parent looks at the fact
3865 that the children are dying gracefully, and starts new children.
3866 Those new children only start enough threads to compliment the number
3867 of threads in the other child process that shares the same spot in
3868 the scoreboard. In this way, we make sure to never go over
3869 MaxClients. [Ryan Bloom]
3871 *) modified mod_negotiation and mod_autoindex to speed up by almost a
3872 factor of two on apr_dir_read()-enhanced platforms, such as Win32
3873 and OS2, by calling ap_sub_request_lookup_dirent() with the results
3874 already provided by apr_dir_read(). [William Rowe]
3876 *) mod_file_cache is now more robust to filtering and serves requests
3877 slightly more efficiently. [Cliff Woolley]
3879 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
3880 Module was calling ap_rwrite() followed by ap_rflush() but the
3881 served content was not being displayed in the browser. Inspection
3882 of the output stream revealed that the first data chunk was
3883 missing the trailing CRLF required by the RFC. [Bill Stoddard]
3885 *) apxs no longer generates ap_send_http_header() in the example handler
3887 *) Fix an ab problem which could cause a divide-by-zero exception
3888 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
3889 [Ian Holsman <ianh cnet.com>]
3891 *) Solve case-insensitive platforms' confusion about negotiated
3892 filenames, allowing files of differnt case to match in choosing
3893 the document to serve. [William Rowe]
3895 *) Fix brokenness when ThreadsPerChild is higher than the built-in
3896 limit. We left ap_threads_per_child at the higher value which
3897 led to segfaults when doing certain scoreboard operations.
3900 *) Fix seg faults and/or missing output from mod_include. The
3901 default_handler was using the subrequest pool for files and
3902 MMAPs, even though the associated APR structures typically
3903 live longer than the subrequest. [Greg Ames]
3905 *) Extend mod_setenvif to support specifying regular expressions
3906 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
3907 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
3908 will cause HAVE_TS to be set if any of the request headers begins
3909 with "TS" and has a value that begins with any character in the
3910 set [a-z]. [Bill Stoddard]
3912 *) httpd children now re-bind themselves to a random CPU on
3913 multiprocessor systems on AIX via bindprocessor() in 2.0.
3914 [Victor J. Orlikowski]
3916 *) Fix htdigest. It would go into a loop in getline when adding
3917 a second user. [Bill Stoddard]
3919 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
3921 *) Automatically generate httpd.exp for AIX.
3922 DSOs now work again on AIX in 2.0
3923 [Victor J. Orlikowski]
3925 *) Add a new request hook, error_log. This phase allows modules
3926 to act on the error log string _after_ it has been written
3927 to the error log. The goal for this hook is to allow monitoring
3928 modules to send the error string to the monitoring agent.
3931 *) Modify mod_echo to make it use filters for input and output.
3932 [Ryan Morgan <rmorgan covalent.net>]
3934 *) Extend mod_headers to support conditional driven Header
3935 add, append and set. Use SetEnvIf to set an envar and conditionally
3936 add/append/set headers based on this envar thusly:
3938 SetEnvIf TSMyHeader value HAVE_TSMyHeader
3939 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
3941 If the request contains header "TSMyHeader: value" then header
3942 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
3945 *) Extend mod_headers to support using format specifiers on Header
3946 add, append and set header values. Two format specifiers are supported:
3948 %t - reports, in UTC microseconds since the epoch, when the
3949 request was received.
3951 %D - reports the time, in microseconds, between when the request was
3952 received and the response sent.
3955 Header add MyHeader "This request served in %D microseconds. %t"
3957 results in a header being added to the response that looks like this:
3959 MyHeader: This request served in D=5438 microseconds. t=991424704447256
3963 *) Fix reset_filter(). We need to be careful how we remove filters.
3964 If we set r->output_filters to NULL, we also have to reset the
3965 connection's filters. [John Sterling]
3967 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
3969 *) Add a check to ap_die() to make sure the filter stack is sane and
3970 contains the correct basic filters when an error occurs. This fixes
3971 a problem where headers are not being sent on error. [John Sterling]
3973 *) New Header directive 'echo' option. "Header echo regex" will
3974 cause any headers received on the request that match regex to be
3975 echoed to (included in) the response headers.
3978 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
3979 This prevented the inclusion of apr_compat.h. PR #7773
3980 [Oleg Broytmann <phd phd.pp.ru>]
3982 *) Moved util_uri to the apr-util library. This required a bunch of
3983 apr_name changes for the uri utility functions. [Justin Erenkrantz]
3985 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
3986 insert_filter phase so that other filters are not bypassed by default.
3989 *) Reimplement mod_headers as an output filter. mod_headers can now
3990 add custom headers to inbound requests using the RequestHeader directive
3991 and to responses using the same old Header directive. [Graham Leggett]
3993 Changes with Apache 2.0.18
3995 *) Fix command-line processing so that if a bad argument is specified
3996 Apache will exit. [Jeff Trawick]
3998 *) Change the make targets and rules to be consistent in all of the
3999 Apache-owned source trees. [Roy Fielding]
4001 *) Fix processing of the TRACE method. Previously we passed bogus
4002 parms to form_header_field() and it overlaid some vhost structures,
4003 resulting in a segfault in check_hostalias().
4004 [Greg Ames, Jeff Trawick]
4006 *) Win32: Add support for reliable piped logs. If the logging process
4007 goes down, Apache will automatically restart it. This function has
4008 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
4011 *) Do not start piped log processes during the config file
4012 preflight. This change also circumvents a problem on
4013 Windows where the rotatelog processes created during preflight
4014 was not getting cleaned up properly.
4017 *) add "Request Phase Participation" info to mod_info
4020 *) Make first phase changes to the scoreboard data structures in
4021 preparation for the rewriting of the scoreboard per my posted
4022 design notes. [Paul J. Reder]
4024 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
4025 and apr-util, allow it to be overridden by the configure command-line
4026 (default="--silent") and introduce LT_LDFLAGS to replace what we were
4027 formerly abusing as LTFLAGS. [Roy Fielding]
4029 *) Clean up the reporting of incorrect closing container tags.
4030 [Barrie Slaymaker <barries slaysys.com>]
4032 *) Simplify the configure process by moving all libtool stuff to APR
4033 and moving hints.m4 inline. [Roy Fielding]
4035 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
4036 of functions used by mod_proxy for export in the DLL
4037 [Ian Holsman <IanH cnet.com>]
4039 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
4040 request body from its stdin but no reqest body is being written to
4041 the cgi. [Jeff Trawick]
4043 *) mod_log_config: %c connection status incorrectly logged
4044 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
4047 *) Get mod_cern_meta working under Windows
4050 *) Create Files, and thus MMAPs, out of the request pool, not the
4051 connection pool. This solves a small resource leak that had us
4052 not closing files until a connection was closed. In order to do
4053 this, at the end of the core_output_filter, we loop through the
4054 brigade and convert any data we have into a single HEAP bucket
4055 that we know will survive clearing the request_rec.
4056 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
4059 *) Completely revamp configure so that it preserves the standard make
4060 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
4061 the configure additions to EXTRA_* variables. Also, allow the user
4062 to specify NOTEST_* values for all of the above, which eliminates the
4063 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
4064 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
4065 avoid pointless duplications. Fix the order in which flags are given
4066 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
4067 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
4068 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
4069 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
4071 *) Get mod_tls to compile/work better on Windows. PR #7612
4072 [Bernhard Schrenk <b.schrenk improx.com>]
4074 *) Fix shutdown/restart hangs in the threaded MPM.
4075 [Jeff Trawick, Greg Ames, Ryan Bloom]
4077 *) Removed the keptalive boolean from conn_rec because it is now only
4078 used by a single routine and can be replaced by a local variable.
4079 [Greg Stein, Ryan Bloom, Roy Fielding]
4081 *) Patch prefork to put enough of the signal processing back in so that
4082 signals are all handled properly now. The previous patch fixed the
4083 deadlock race condition, but broke the user directed signal handling.
4084 This fixes it to work the way it did before my previous prefork patch
4085 (primarily, SIGTERM is now working).
4087 *) Change how input filters decide how much data is returned to the
4088 higher filter. We used to use a field in the conn_rec, with this
4089 change, we use an argument to ap_get_brigade to determine how much
4090 data is retrieved. [Ryan Bloom]
4092 *) Fix seg fault at start-up introduced by Ryan's change to enable
4093 modules to specify their own logging tags. mod_log_config
4094 registers an optional function, ap_register_log_handler().
4095 ap_register_log_handler() was being called by http_core before
4096 the directive hash table was created. This patch creates the
4097 directive hash table before ap_register_log_handler() is
4098 registered as an optional function.
4099 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4101 *) Add ap_set_int_slot() function
4102 [John K. Sterling <sterling covalent.net>]
4104 *) Under certain circumstances, Apache did not supply the
4105 right response headers when requiring authentication.
4106 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
4107 (This is a port of the change that went into Apache 1.3.19.)
4109 *) Allow modules to specify their own logging tags. This basically
4110 allows a module to tell mod_log_config that when %x is encountered
4111 a specific function should be called. Currently, x can be any single
4112 character. It may be more useful to make this a string at some point.
4115 Changes with Apache 2.0.17
4117 *) If a higher-level filter handles the byterange aspects of a
4118 request, then the byterange filter should not try to redo the
4119 work. The most common case of this happening, is a byterange
4120 request going through the proxy, and the origin server handles
4121 the byterange request. The proxy should ignore it.
4122 [Graham Leggett <minfrin sharp.fm>]
4124 *) Changed the threaded mpm to have child_main join to each of the
4125 worker threads to make sure the kids are all gone before child_main
4126 exits after a signal (cleanup from perform_idle_server_maintenance).
4127 This is an extension of Ryans recent commit to make the child_main
4130 *) Add more options to the ap_mpm_query function. This also allows MPMs to
4131 report if their threads are dynamic or static. Finally, this also
4132 implements a new API, ap_show_mpm, which returns the MPM that was
4133 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
4135 *) Do not install the binaries from the support directory twice.
4136 [jun-ichiro hagino <itojun iijlab.net>]
4138 *) The ap_f* functions should flush data to the filter that is passed
4139 in, not the filter after the one passed in.
4140 [Ryan Morgan <rmorgan covalent.net>]
4142 *) Make ab work again by changing its native types to apr types and formats.
4143 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4145 *) Move the byterange filter and all of the supporting functions back
4146 to the HTTP module. The byterange filter turned out to be very
4147 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
4149 *) Make clean, distclean, and extraclean consistently according to the
4150 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4152 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
4153 This may have been causing problems stopping processes in the threaded
4156 *) Fix content-length in mod_negotiation to a long int representation.
4159 *) Remove BindAddress from the default config file.
4160 [<giles nemeton.com.au>]
4162 *) Allow module authors to add a module to their Apache build using
4163 --with-module, without re-running buildconf. The syntax is:
4164 --with-module=module_type:/path/to/module.c
4165 The configure script will copy the module.c file to
4166 modules/module_type, and it will be added to the relevant Makefiles.
4167 currently, this only works for static modules. [Ryan Bloom]
4169 *) Changes required to make prefork clean up idle children properly.
4170 There was a window during which a starting worker deadlocks when
4171 an idle cleanup arrives before it completes init. Apache then keeps
4172 trying to cleanup the same deadlocked worker forever (until higher
4173 pids come along, but it still will never reduce below the deadlocked
4174 pid). Thus the number of children would not reduce to the correct
4175 idle level. [Paul J. Reder]
4177 Changes with Apache 2.0.16
4179 *) Change the default installation directory to /usr/local/apache2,
4180 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
4182 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
4185 *) Get MaxRequestsPerChild working with the Windows MPM.
4188 *) Make generic hooks to work, with mod_generic_hook_import/export
4189 experimental modules. [Ben Laurie, Will Rowe]
4191 *) Fix segfaults for configuration file syntax errors such as
4192 "<Directory>" followed by "</Directory" and
4193 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
4195 *) Cleanup the --enable-layout option of configure. This makes
4196 us use a consistent location for the config.layout file, and it
4197 makes configure more portable.
4198 [jun-ichiro hagino <itojun iijlab.net>]
4200 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
4201 csv/gnuplot format, rudimentary ssl support and various other tweaks
4202 to make results more true to what is measured. The upshot of this it
4203 turns out that 'ab' has often underreported the true performance of
4204 apache. Often by a order of magnitude :-) See talk/paper of Sander
4205 Temme at April ApacheCon 2001 for details.
4206 [Dirk-Willem van Gulik]
4208 *) Clean up mod_cgid's temporary request pool. Besides fixing a
4209 storage leak this ensures that some unnecessary pipes are closed.
4212 *) Performance: Add quick_handler hook. This hook is called at the
4213 very beginning of the request processing before location_walk,
4214 translate_name, etc. This hook is useful for URI keyed content
4215 caches like Mike Abbott's Quick Shortcut Cache.
4218 *) top_module global variable renamed to ap_top_module [Perl]
4220 *) Move ap_set_last_modified to the core. This is a potentially
4221 controversial change, because this is kind of HTTP specific. However
4222 many protocols should be able to take advantage of this kind of
4223 information. I expect that headers will need one more layer of
4224 indirection for multi-protocol work, but this is a small step in
4225 the right direction. [Ryan Bloom]
4227 *) Enable mod_status by default. This matches what Apache 1.3 does.
4230 *) Add a ScriptSock directive to the default config file. This is
4231 only enabled when mod_cgid is used.
4232 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4234 Changes with Apache 2.0.15
4236 *) Untangled the buildconf script and eliminated the need for build's
4237 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
4238 libtool muck that is now under srclib/apr/build. [Roy Fielding]
4240 *) Win32: Don't accept more connections than we have worker threads
4244 *) Fix bug in the Unix threaded.c MPM that allowed child processes
4245 to fork() new child processes.
4248 *) SECURITY: Fix a major security problem with double-reverse lookup
4249 checking. Previously, a client connecting over IPv4 would not be
4250 matched properly when the server had an IPv6 listening socket.
4251 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
4253 *) Change the way the beos MPM handles polling to allow it to stop and
4254 restart. Problem was the sockets being polled were being reset by
4255 the select call, so once it had accepted a connection it was no
4256 longer listening on the UDP socket we use for shutdown instructions.
4257 APR needs to be altered, patch on it's way. [David Reid]
4259 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
4260 on error exit from ap_getline(). Some other code got upset because
4261 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
4263 *) Handle ap_discard_request_body() being called more than once.
4264 [Greg Ames, Jeff Trawick]
4266 *) Get rid of an inadvertent close of file descriptor 2 in
4267 mod_mime_magic. [Greg Ames, Jeff Trawick]
4269 *) Add a hook, create_request. This hook allows modules to modify
4270 a request while it is being created. This hook is called for all
4271 request_rec's, main request, sub request, and internal redirect.
4272 When this hook is called, the r->main, r->prev, r->next
4273 pointers have been set, so modules can determine what kind of
4274 request this is. [Ryan Bloom]
4276 *) Cleanup the build process a bit more. The Apache configure
4277 script no longer creates its own helper scripts, it just
4279 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4281 *) Stop the forced downgrade of the connection to HTTP/1.0 for
4282 proxy requests. [Graham Leggett]
4284 *) Avoid using sscanf to determine the HTTP protocol number in
4285 the common case because sscanf is a performance hog. From
4286 Mike Abbot's Accelerating Apache patch number 6.
4287 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
4289 *) SECURITY: Fix a security exposure in mod_access. Previously when
4290 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
4291 were not evaluated properly (PR #7407). Also, add the ability to
4292 specify IPv6 address strings with optional prefix length on Allow
4293 and Deny. [Jeff Trawick]
4295 *) Enhance rotatelogs so that a UTC offset can be specified, and
4296 the logfile name can be formatted using strftime(3). (Brought
4297 forward from 1.3.) [Ken Coar]
4299 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
4300 DuplicateHandle on an IOCompletionPort (a practice which
4301 MS "discourages"). The new model does not rely on associating
4302 the completion port with the listening sockets, thus the
4303 completion port can be completely managed within the child
4304 process. A dedicated thread accepts connections off the network,
4305 then calls PostQueuedCompletionStatus() to wake up worker
4306 threads blocked on the completion port.
4309 *) Bring forward the --suexec-umask option which allows the
4310 builder to preset the umask for suexec processes. [Ken Coar]
4312 *) Add a -V flag to suexec, which causes it to display the
4313 compile-time settings with which it was built. (Only
4314 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
4316 *) Mod_include should always unset the content-length if the file is
4317 going to be passed through send_parsed_content. There is no to
4318 determine if the content will change before actually scanning the
4319 entire content. It is far safer to just remove the C-L as long
4320 as we are scanning it. [Ryan Bloom]
4322 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
4323 request and not Proxy-Authenticate.
4324 [Graham Leggett <minfrin sharp.fm>]
4326 Changes with Apache 2.0.14
4328 *) Fix content-length computation. We ONLY compute a content-length if
4329 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
4330 or we already have all the data. [Ryan Bloom]
4332 *) Report unbounded containers in the config file. Previously, a typo
4333 in the </container> directive could result in the rest of the config
4334 file being silently ignored, with undesired defaults used.
4337 *) Make the old_write filter use the ap_f* functions for the buffering.
4340 *) Move more code from the http module into the core server. This
4341 is core code, basically the default handler, the default input
4342 and output filters, and all of the core configuration directives.
4343 All of this code is required in order for the server to work, with or
4344 without HTTP. The server is closer to working without the HTTP
4345 module, although there is still more to do. [Ryan Bloom]
4347 *) Fix a number of SGI compile warnings throughout the server. Fix some
4348 bad parameters to apr_bucket_read(). Fix a bad statement in
4349 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
4350 consistently; we were mixing apr_time_t and time_t in invalid ways
4351 before. In load_file(), call apr_dso_error() instead of
4352 apr_strerror() so that we get a more specific string on some platforms.
4353 PR #6980 [Jeff Trawick]
4355 *) Allow modules to query the MPM about it's execution profile. This
4356 query API can and should be extended in the future, but for now,
4357 max_daemons, and threading or forking is a very good start.
4358 [Jon Travis <jtravis covalent.net>]
4360 *) Modify mod_include to send blocks of data no larger than 9k.
4361 Without this, mod_include will wait until the whole file is parsed,
4362 or the first tag is found to send any data to the client.
4363 [Paul J. Reder <rederpj raleigh.ibm.com>]
4365 *) Fix mod_info, so that <Directory> and <Location> directives are
4366 not displayed twice when displaying the current configuration.
4367 [Ryan Morgan <rmorgan covalent.net>]
4369 *) Add config directives to override DEFAULT_ERROR_MSG and
4370 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
4371 [Dan Rench <drench xnet.com>]
4373 *) Get mod_info building and loading on Win32. [William Rowe]
4375 *) Begin to move protocol independant functions out of mod_http. The goal
4376 is to have only functions that are HTTP specific in the http directory.
4379 Changes with Apache 2.0.13
4381 *) Don't assume that there will always be multiple calls to the byterange
4382 filter. It is possible that we will need to do byteranges with only
4383 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
4385 *) Move the error_bucket definition from the http module to the
4386 core server. Every protocol will need this ability, not just
4389 Changes with Apache 2.0.12
4391 *) Modify mod_file_cache to save pre-formatted strings for
4392 content-length and last-modified headers for performance.

4395 *) Namespace protect IOBUFSIZ since it is exposed in the API.
4396 [Jon Travis <jtravis covalent.net>]

4399 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
4401 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
4402 without ever filling it out. This fixes PR 7271.
4403 [Taketo Kabe <kabe sra-tohoku.co.jp> and
4404 Cliff Woolley <cliffwoolley yahoo.com>]
4406 *) Add a couple of GCC attribute tags to printf style functions.
4407 [Jon Travis <jtravis covalent.net>]
4409 *) Add the correct language tag for interoperation with the Taiwanese
4410 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
4412 *) Migrate the perchild MPM to use the new apr signal child, and
4413 APR thread functions. [Ryan Bloom]
4415 *) Close one copy of the CGI's stdout before creating the new process.
4416 The CGI will still have stdout, because we have already dup'ed it.
4417 This keeps Apache from waiting forever to send the results of a CGI
4418 process that has forked a long-lived child process.
4419 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4421 *) Remove the rest of the pthreads functions from the threaded MPM.
4422 This requires the APR support for a signal thread that was just
4425 *) Make mod_dir use a fixup for sending a redirect to the browser.
4426 Before this, we were using a handler, which doesn't make much
4427 sense, because the handler wasn't generating any data, it would
4428 either return a redirect error code, or DECLINED. This fits the
4429 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
4431 *) Make the threaded MPM use APR threads instead of pthreads.
4434 *) Get mod_tls to the point where it actually appears to work in all cases.
4437 *) implement --enable-modules and --enable-mods-shared for "all" and
4438 "most". [Greg Stein]
4440 *) Move the threaded MPM to use APR locks instead of pthread locks.
4443 *) Rename mpmt_pthread to threaded. This is more in line with the
4444 fact that mpmt_pthread shouldn't be using pthreads directly, and
4445 it is a smaller name that doesn't tie into anything.
4448 *) Rename the module structures so that the exported symbol matches
4449 the file name, and it is easier to automate the installation
4450 process (generating LoadModule directives from the module filenames).
4453 *) Remove the coalesce filter. With the ap_f* functions, this filter
4454 is no longer needed. [Ryan Bloom]
4456 Changes with Apache 2.0.11
4458 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
4459 added feature of allowing a uid/gid per child process. If no
4460 uid/gid is specified, then Perchild behaves exactly like dexter.
4463 *) Get perchild building again. [Ryan Bloom]
4465 *) Don't disable threads just because we are using the prefork MPM.
4466 If somebody wants to compile without threads, they must now add
4467 --disable-threads to the configure command line. [Ryan Bloom]
4469 *) Begin to move the calls to update_child_status into common code, so
4470 that each individual MPM does not need to update the scoreboard itself.
4473 *) Allow mod_tls to compile under Unix boxes where openssl has been
4474 installed to the system include files.
4475 [Gomez Henri <new-httpd slib.fr>]
4477 *) Cleanup the mod_tls configure process. This should remove any need
4478 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
4479 configure doesn't check that yet. [Ryan Bloom]
4481 *) Add a very early prototype of SSL support (in mod_tls.c). It is
4482 vital that you read modules/tls/README before attempting to build
4485 *) Fix a potential seg fault on all platforms. David Reid fixed this
4486 on BEOS, but the problem could happen anywhere, so we don't want
4487 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
4489 *) Add new LogFormat directive, %D, to log time it takes to serve a
4490 request in microseconds. [Bill Stoddard]
4492 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
4493 SetOutputFilter. This corresponds nicely with the other Set
4494 directives, which operate on containers while the Add* directives
4495 tend to work directly on extensions. [Ryan Bloom]
4497 *) Cleanup the header handling a bit. This uses the apr_brigade_*
4498 functions for the buffering so that we don't need to compute
4499 the length of the headers before we actually create the header
4500 buffer. [Ryan Bloom]
4502 *) Allow filters to buffer data using the ap_f* functions. These have
4503 become macros that resolve directly to apr_brigade_*.
4506 *) Get the Unix MPM's to do a graceful restart again. If we are going
4507 to register a cleanup with ap_cleanup_scoreboard, then we have to
4508 kill the cleanup with the same function, and that function can't be
4509 static. [Ryan Bloom]
4511 *) Install all required header files. Without these, it was not
4512 possible to compile some modules outside of the server.
4515 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
4516 forward from 1.3 to 2.0, we missed a single line, which broke regex
4517 aliases. [Ryan Bloom]
4519 *) We have a poor abstraction in the protocol. This is a temporary
4520 hack to fix the bug, but it will need to be fixed for real. If
4521 we find an error while sending out a custom error response, we back
4522 up to the first non-OK request and send the data. Then, when we send
4523 the EOS from finalize_request_protocol, we go to the last request,
4524 to ensure that we aren't sending an EOS to a request that has already
4525 received one. Because the data is sent on a different request than
4526 the EOS, the error text never gets sent down the filter stack. This
4527 fixes the problem by finding the last request, and sending the data
4528 with that request. [Ryan Bloom]
4530 *) Make the server status page show the correct restart time, and
4531 thus the proper uptime. [Ryan Bloom]
4533 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
4534 should reduce the amount of duplicate code that is required to
4535 create CGI processes.
4536 [Paul J. Reder <rederpj raleigh.ibm.com>]
4538 *) ap_new_connection() closes the socket and returns NULL if a socket
4539 call fails. Usually this is due to a connection which has been
4540 reset. [Jeff Trawick]
4542 *) Move the Apache version information out of httpd.h and into release.h.
4543 This is in preparation for the first tag with the new tag and release
4544 system. [Ryan Bloom]
4546 *) Begin restructuring scoreboard code to enable adding back in
4547 the ability to use IPC other than shared memory.
4548 Get mod_status working on Windows again. [Bill Stoddard]
4550 *) Make mod_status work with 2.0. This will work for prefork,
4551 mpmt_pthread, and dexter. [Ryan Bloom]
4553 *) Correct a typo in httpd.conf.
4554 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
4556 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
4558 *) Get the correct IP address if ServerName isn't set and we can't
4559 find a fully-qualified domain name at startup.
4560 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
4562 *) Make mod_cgid work with SuExec. [Ryan Bloom]
4564 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
4565 'extra' stat's for user/group since they should never occur, and now
4566 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
4567 volumes. [William Rowe]
4569 *) Adopt apr features to simplify mod_includes. This changes the
4570 behavior of the USER_NAME variable, unknown uid's are now reported
4571 as USER_NAME="<unknown>" rather than the old user#000 result.
4572 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
4574 *) Adopt apr features for simplifing mod_userdir, and accept the new
4575 Win32/OS2 exceptions without hiccuping. [William Rowe]
4577 *) Replace configure --with-optim option by using and saving the
4578 environment variable OPTIM instead. This is needed because configure
4579 options do not support multiple flags separated by spaces.
4582 *) Fix some byterange handling. If we get a byte range that looks like
4583 "-999999" where that is past the end of the file, we should return
4584 a PARTIAL CONTENT status code, and return the whole file as one big
4585 byterange. This matches the 1.3 handling now. [Ryan Bloom]
4587 *) Make the error bucket a real meta-data bucket. This means that the
4588 bucket length is 0, and a read returns NULL data. If one of these
4589 buckets is passed down after the headers are sent, this data will
4590 just be ignored. [Greg Stein]
4592 *) The prefork MPM wasn't killing child processes correctly if a restart
4593 signal was received while the process was serving a request. The child
4594 process would become the equivalent of a second parent process. If
4595 we break out of the accept loop, then we need to do die after cleaning
4596 up after ourselves. [Ryan Bloom]
4598 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
4599 restarts. [Ryan Bloom]
4601 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
4602 the most optimal APR_FINFO_wanted bits. This spares Win32 from
4603 performing very expensive owner, group and permission lookups
4604 and allows the server to function until these apr_finfo_t fields
4605 are implemented under Win32. [William Rowe]
4607 *) Support for typedsafe optional functions - that is functions exported by
4608 optional modules, which, therefore, may or may not be present, depending
4609 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
4610 for sample code. [Ben Laurie]
4612 *) filters can now report an HTTP error to the server. This is done
4613 by sending a brigade where the first bucket is an error_bucket.
4614 This bucket is a simple bucket that stores an HTTP error and
4615 a string. Currently the string is not used, but it may be needed
4616 to output an error log. The http_header_filter will find this
4617 bucket, and output the error text, and then return
4618 AP_FILTER_ERROR, which informs the server that the error web page
4619 has already been sent. [Ryan Bloom]
4621 *) If we get an error, then we should remove all filters except for
4622 those critical to serving a web page. This fixes a bug, where
4623 error pages were going through the byterange filter, even though
4624 that made no sense. [Ryan Bloom]
4626 *) Relax the syntax checking of Host: headers in order to support
4627 iDNS. PR#6635 [Tony Finch]
4629 *) Cleanup the byterange filter to use the apr_brigade_partition
4630 and apr_bucket_copy functions. This removes a lot of very messy
4631 code, and hopefully makes this filter more stable.
4634 *) Remove AddModule and ClearModuleList directives. Both of these
4635 directives were used to ensure that modules could be enabled
4636 in the correct order. That requirement is now gone, because
4637 we use hooks to ensure that modules are in the correct order.
4640 *) When SuExec is specified, we need to add it to the list of
4641 targets to be built. If we don't, then any changes to the
4642 configuration won't affect SuExec, unless 'make suexec' is
4643 specifically run. [Ryan Bloom]
4645 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4646 the APR_XTHREAD argument to open a file for consumption by
4647 parallel threads on win32. [William Rowe]
4649 *) Correct a bug in determining when we follow symlinks. The code
4650 expected a stat -1 result, not an apr_status_t positive error.
4651 Also check if the APR_FINFO_USER fields are valid before we
4652 follow the link. [William Rowe]
4654 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4655 mpm_common.c. These functions are only valid on some platforms,
4656 so they should not be in the main-line code. [Ryan Bloom]
4658 *) Remove ap_chdir_file(). This function is not thread-safe,
4659 and nobody is currently using it. [Ryan Bloom]
4661 *) Do not try to run make depend if there are no .c files in the
4662 current directory, doing so makes `make depend` fail.
4665 *) Update highperformance.conf to work with either prefork or
4666 pthreads mpms. [Greg Ames]
4668 *) Stop checking to see if this is a pipelined request if we know
4669 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4670 This keeps us from making an extra read call when serving a 1.0
4671 request. [Ryan Bloom and Greg Stein]
4673 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4674 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4675 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4677 *) Fix the RFC number mentioned when complaining about a missing
4678 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
4680 *) Fix an endless loop in ab which occurred when ab was posting
4681 and the server dropped the connection unexpectedly.
4684 *) Fix a segfault while handling request bodies in ap_http_filter().
4685 This problem has been seen with mod_dav usage as well as with
4686 requests where the body was just being discarded. [Jeff Trawick]
4688 *) Some adjustment on the handling and automatic setting (via
4689 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4690 add the capability to specify flags (NOTEST_CFLAGS and
4691 NOTEST_LDFLAGS) which are used to compile Apache, but
4692 not used during the configuration process. Useful for
4693 flags like "-Werror". [Jim Jagielski]
4695 *) Stop using environment variables to force debug mode or
4696 no detach. We now use the -D command line argument to
4697 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4698 [Greg Stein, Ryan Bloom]
4700 *) Change handlers to use hooks. [Ben Laurie]
4702 *) Stop returning copies of filenames from both apr_file_t and
4703 apr_dir_t. We pstrdup the filenames that we store in the
4704 actual structures, so we don't need to pstrdup the strings again.
4707 *) mod_cgi: Fix some problems where the wrong error value was being
4708 traced. [Jeff Trawick]
4710 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
4713 *) Add generic hooks. [Ben Laurie]
4715 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
4717 *) Fix a segfault caused by mod_ext_filter when the external filter
4718 program does not exist. [Jeff Trawick]
4720 *) Fix an output truncation error when on an HTTP >= 1.0 request an
4721 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
4722 was served through mod_charset_lite (or anything else that would
4723 create a transient bucket in this size range). ap_bucket_make_heap()
4724 silently failed (fixed), transient_setaside() discovered it, but
4725 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
4727 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
4728 is that some browsers send extra lines at the end of POST requests, and
4729 we don't want to delay sending data back to the user just because the
4730 browser isn't well behaved. [Ryan Bloom]
4732 *) Get SuEXEC working again. We can't send absolute paths to suExec
4733 because it refuses to execute those programs. SuEXEC also wasn't
4734 always recognizing configuration changes made using the autoconf
4737 *) Allow the buildconf process to find the config.m4 files in the correct
4738 order. Basically, we can now name config.m4 files as config\d\d.m4,
4739 and we will sort them correctly when inserting them into the build
4740 process. [Ryan Bloom]
4742 *) Get mod_cgid to use apr calls for creating the actual CGI process.
4743 This also allows mod_cgid to use ap_os_create_priviledged_process,
4744 thus allowing for SuExec execution from mod_cgid. Currently, we do
4745 not support everything that standard SuExec supports, but at least
4746 it works minimally now. [Ryan Bloom]
4748 *) Allow SuExec to be configured from the ./configure command line.
4751 *) Update some of the docs in README and INSTALL to reflect some of
4752 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
4754 *) If we get EAGAIN returned from the call to apr_sendfile, then we
4755 need to call sendfile again. This gets us serving large files
4756 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
4758 *) Get the support programs building cleanly again.
4759 [Cliff Woolley <cliffwoolley yahoo.com>]
4761 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
4762 current directory logic now backs up over bin/ to determine the
4763 server root from the Apache.exe path.
4765 *) Apache/Win32 now follows the standard conventions of mod_foo.so
4766 loadable modules, dynamic libs are all named libfoo.dll, and the
4767 makefile.win populates the include, lib and libexec directories.
4769 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
4770 Apache gets IPv6 listening sockets by default. Additionally, the
4771 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
4772 numeric address strings (e.g., "Listen [fe80::1]:8080").
4775 *) Modify the install directory layout. Modules are now installed in
4776 modules/. Shared libraries should be installed in libraries/, but
4777 we don't have any of those on Unix yet. All install directories
4778 are modifyable at configure time. [Ryan Bloom]
4780 *) Install all header files in the same directory on Unix. [Ryan Bloom]
4782 *) Get the functions in server/linked into the server, regardless of
4783 which modules linked into the server. This uses the same hack
4784 for Apache that we use for APR and apr-util to ensure all of the
4785 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
4786 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
4787 the scripts a bit easier.
4790 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
4791 on the query, and remove IPv4 dependencies. [Jeff Trawick]
4793 *) Get all of the auth modules to the point that they will install and
4794 be loadable into the server. Our new build/install mechanism expects
4795 that all modules will have a common name format. The auth modules
4796 didn't use that format, so we didn't install them properly.
4799 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
4800 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
4802 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
4804 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
4805 after the end of the response. [Ryan Bloom]
4807 *) Get byterange requests working with responses that do not have a
4808 content-length. Because of the way byterange requests work, we have to
4809 have all of the data before we can actually do the byterange, so we
4810 can compute the content-length in the byterange filter.
4813 *) Get exe CGI's working again on Windows.
4816 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
4817 they keep track of whether or not their post config hook has been
4818 called before. Instead of a static variable (which is replaced when
4819 the DSO is loaded a second time), use userdata in the process pool.
4822 Changes with Apache 2.0a9
4824 *) Win32 now requires perl to complete the final install step for users
4825 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
4826 and installs the conf, htdocs and htdocs/manual directories.
4829 *) Make mod_include use a hash table to associate directive tags with
4830 functions. This allows modules to implement their own SSI tags easily.
4831 The idea is simple enough, a module can insert it's own tag and function
4832 combination into a hash table provided by mod_include. While mod_include
4833 parses an SSI file, when it encounters a tag in the file, it does a
4834 hash lookup to find the function that implements that tag, and passes
4835 all of the relevant data to the function. That function is then
4836 responsible for processing the tag and handing the remaining data back
4837 to mod_include for further processing.
4838 [Paul J. Reder <rederpj raleigh.ibm.com>]
4840 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
4841 fewer parameters: the local and remote socket addresses were removed
4842 from the parameter list because all required information is available
4843 via the APR socket. [Jeff Trawick]
4845 *) Distribution directory structure reorganized to reflect a
4846 normal source distribution with external install targets.
4849 *) The MPMs that need multiple segments of shared memory now create
4850 two apr_shmem_t variables, one for each shared memory allocation.
4851 the problem is that we can't determine how much memory will be required
4852 for shared memory allocations once we try to allocate more than one
4853 variable. The MM code automatically aligns the shared memory allocations,
4854 so we end up needing to pad the amount of shared memory we want based
4855 on how many variables will be allocated out of the shared memory segment.
4856 It is just easier to create a second apr_shmem_t variable, and two
4857 shmem memory blocks.
4860 *) Cleanup the export list a bit. This creates a single unified list of
4861 functions exported by APR. The export list is generated at configure
4862 time, and that list is then used to generate the exports.c file.
4863 Because of the way the export list is generated, we only export those
4864 functions that are valid on the platform we are building on.
4867 *) Enable logging the cookie with mod_log_config
4868 [Sander van Zoest <sander covalent.net>]
4870 *) Fix a segfault in mod_info when it reaches the end of the configuration.
4873 *) Added lib/aputil/ as a placeholder for utility functions which are not
4874 specific to the Apache HTTP Server (but do not make sense with APR).
4875 The first utility is "apu_dbm": a set of functions to work with DBM
4876 files. This first version can be compiled for SDBM or GDBM databases.
4879 *) Complete re-write of mod_include. This makes mod_include a filter that
4880 uses buckets directly. This has now served the FAQ correctly.
4881 [Paul Reder <rederpj raleigh.ibm.com>]
4883 *) Allow modules to specify the first filter in a sub_request when
4884 making the sub_request. This keeps modules from having to change the
4885 output_filter immediately after creating the sub-request, and therefore
4886 skip the sub_req_output_filter. [Ryan Bloom]
4888 *) Update ab to accept URLs with IPv6 literal address strings (in the
4889 format described in RFC 2732), and to build Host header fields in
4890 the same format. This allows IPv6 literal address strings to be
4891 used with ab. This support has been tested against Apache 1.3 with
4892 the KAME patch, but Apache 2.0 does not yet work with this format
4893 of the Host header field. [Jeff Trawick]
4895 *) Accomodate an out-of-space condition in the piped logs and the
4896 rotatelogs.c code, and no longer churn log processes for this
4897 condition. [Victor J. Orlikowski]
4899 *) Add support for partial writes with apr_sendfile() to core_output_filter.
4902 Changes with Apache 2.0a8
4904 *) Add a directive to mod_mime so that filters can be associated with
4908 *) Get multi-views working again. We were setting the path_info
4909 field incorrectly if we couldn't find the specified file.
4912 *) Fix 304 processing. The core should never try to send the headers
4913 down the filter stack. Always, just setup the table in the request
4914 record, and let the header filter convert it to data that is ready
4918 *) More fixes for the proxy. There are still bugs in the proxy code,
4919 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
4923 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
4926 *) APR: Add new apr_getopt_long function to handle long options.
4927 [B. W. Fitzpatrick <fitz red-bean.com>]
4929 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
4930 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
4931 hostname resolution/address string parsing and building
4932 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
4933 of one of the apr_sockaddr_t structures for a socket. Change
4934 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
4936 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
4937 I have proxied pages with it, cleanup will commence soon.
4940 *) Make the proxy work with filters. This isn't perfect, because we
4941 aren't dealing with the headers properly. [Ryan Bloom]
4943 *) Do not send a content-length iff the C-L is 0 and this is a head
4944 request. [Ryan Bloom]
4946 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
4947 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
4949 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
4951 *) Get the default_handler to stop trying to deal with HEAD requests.
4952 The idea is to let the content-length filter compute the C-L before
4953 we try to send the data. If we can get the C-L correctly, then we
4954 should send it in the HEAD response.
4957 *) The Header filter can now determine if a body should be sent based
4958 on r->header_only. The general idea of this is that if we delay
4959 deciding to send the body, then we might be able to compute the
4960 content-length correctly, which will help caching proxies to cache
4961 our data better. Any handler that doesn't want to try to compute
4962 the content-length can just send an EOS bucket without data and
4963 everything will just work.
4966 *) Add the referer to the error log if one is available.
4967 [Markus Gyger <mgyger itr.ch>]
4969 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
4970 change, the root of the configuration tree has been exposed to modules
4972 [Ryan Morgan <rmorgan covalent.net>]
4974 *) Get the core_output_filter to use the bucket interface directly.
4975 This keeps us from calling the content-length filter multiple times
4976 for a simple static request.
4979 *) We are sending the content-type correctly now.
4980 [Ryan Bloom and Will Rowe]
4982 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
4983 a bogus bytes-sent value when the only thing being sent was trailers
4984 and writev() returned an error (or EAGAIN). [Jeff Trawick]
4986 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
4987 hints file to determine which platforms define
4988 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
4991 *) APR: add apr_get_home_directory() [Jeff Trawick]
4993 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
4995 *) Not all platforms have INADDR_NONE defined by default. Apache
4996 used to make this check and define INADDR_NONE if appropriate,
4997 but APR needs the check too, and I suspect other applications will
4998 as well. APR now defines APR_INADDR_NONE, which is always a valid
4999 value on all platforms.
5000 [Branko Èibej <brane xbc.nu>]
5002 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
5003 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
5005 *) Relax the syntax checking of Host: headers in order to support
5006 iDNS. PR#6635 [Tony Finch]
5008 *) When reading from file buckets we convert to an MMAP if it makes
5009 sense. This also simplifies the default handler because the
5010 default handler no longer needs to try to create MMAPs.
5013 *) BUFF has been removed from the main server. The BUFF code will remain
5014 in the code until it has been purged from the proxy module as well.
5017 *) Byteranges have been completely re-written to be a filter. This
5018 has been tested, and I believe it is working correctly, but it could
5019 doesn't work for the Adobe Acrobat plug-in. The output almost matches
5020 the output from 1.3, the only difference being that 1.3 includes
5021 a content-length in the response, and this does not.
5024 *) APR read/write functions and bucket read functions now operate
5025 on unsigned integers, instead of signed ones. It doesn't make
5026 any sense to use signed ints, because we return the error codes,
5027 so if we have an error we should report 0 bytes read or written.
5030 *) Always compute the content length, whether it is sent or not.
5031 The reason for this, is that it allows us to correctly report
5032 the bytes_sent when logging the request. This also simplifies
5033 content-length filter a bit, and fixes the actual byte-reporing
5034 code in mod_log_config.c
5037 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
5038 it says, because it was only used by EOS and FLUSH buckets. Since
5039 neither of those are required at the end of a brigade, this was
5040 really signifying FLUSH_THE_DATA, but that can be determined better
5041 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
5042 buckets now return a length of 0, which is actually the amount of data
5043 read, so they make more sense.
5046 *) Allow the core_output_filter to save some data past the end of a
5047 request. If we get an EOS bucket, we only send the data if it
5048 makes sense to send it. This allows us to pipeline request
5049 responses. As a part of this, we also need to allocate mmap
5050 buckets out of the connection pool, not the request pool. This
5051 allows the mmap to outlive the request.
5054 *) Make blocking and non-blocking bucket reads work correctly for
5055 sockets and pipes. These are the only bucket types that should
5056 have non-blocking reads, because the other bucket types should
5057 ALWAYS be able to return something immediately.
5060 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
5061 server, but use Ctrl+Break to initiate a graceful restart
5062 instead of duplicating behavior. [John Sterling]
5064 *) Patch mod_autoindex to set the Last-Modified header based on
5065 the directory's mtime, and add the ETag header. [William Rowe]
5067 *) Merge the 1.3 patch to add support for logging query string in
5068 such a way that "%m %U%q %H" is the same as "%r".
5071 *) Port three log methods from mod_log_config 1.3 to 2.0:
5072 CLF compliant '-' byte count, method and protocol.
5075 *) Add a new LogFormat directive, %c, that will log connection
5076 status at the end of the response as follows:
5077 'X' - connection aborted before the response completed.
5078 '+' - connection may be kept-alive by the server.
5079 '-' - connection will be closed by the server.
5082 *) Expand APR for WinNT to fully accept and return utf-8 encoded
5083 Unicode file names and paths for Win32, and tag the Content-Type
5084 from mod_autoindex to reflect that charset if the feature
5085 macro APR_HAS_UNICODE_FS is true. [William Rowe]
5087 *) Compute the content length (and add appropriate header field) for
5088 the response when no content length is available and we can't use
5089 chunked encoding. [Jeff Trawick]
5091 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
5092 so that content input filters get dechunked data when using
5093 the default handler. Also removed REQUEST_CHUNKED_PASS.
5096 *) Add mod_ext_filter as an experimental module. This module allows
5097 the administrator to use external programs as filters. Currently,
5098 only filtering of output is supported. [Jeff Trawick]
5100 *) Most Apache functions work on EBCDIC machines again, as protocol
5101 data is now translated (again). [Jeff Trawick]
5103 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
5104 the EBCDIC support. They are noops on ASCII machines, so this
5105 type of translation doesn't have to be surrounded by #ifdef
5106 CHARSET_EBCDIC. [Jeff Trawick]
5108 *) Fix mod_include. tag commands work again, and the server will
5109 send the FAQ again. This also allows mod_include to set aside
5110 buckets that include partial buckets.
5111 [Ryan Bloom and David Reid]
5113 *) Add suexec support back. [Manoj Kasichainula]
5115 *) Lingering close now uses the socket directly instead of using
5116 BUFF. This has been tested, but since all we can tell is that it
5117 doesn't fail, this needs to be really hacked on.
5120 *) Allow filters to modify headers and have those headers be sent to
5121 the client. The idea is that we have an http_header filter that
5122 actually sends the headers to the network. This removes the need
5123 for the BUFF to send headers.
5126 *) Charset translation: mod_charset_lite handles translation of
5127 request bodies. Get rid of the xlate version of ap_md5_digest()
5128 since we don't compute digests of filtered (e.g., translated)
5129 response bodies this way anymore. (Note that we don't do it at
5130 all at the present; somebody needs to write a filter to do so.)
5133 *) Input filters and ap_get_brigade() now have a input mode parameter
5134 (blocking, non-blocking, peek) instead of a length parameter.
5137 *) Update the mime.types file to the registered media types as
5138 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
5141 *) Namespace protect some macros declared in ap_config.h
5144 *) Support HTTP header line folding with input filtering.
5147 *) Mod_include works again. This should still be re-written, but at
5148 least now we can serve an SHTML page again.
5151 *) Begin to remove BUFF from the core. Currently, we keep a pointer
5152 to both the BUFF and the socket in the conn_rec. Functions that
5153 want to use the BUFF can, functions that want to use the socket,
5154 can. They point to the same place.
5157 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
5158 [Tomas "Ögren" <stric ing.umu.se>]
5160 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
5161 associated pool goes away. (APR pipes on OS/2 were already had this
5162 logic.) This resolvs a fatal file descriptor leak with CGIs.
5165 *) The final line of the config file was not being read if there was
5166 no \n at the end of it. This was caused by apr_fgets returning
5167 APR_EOF even though we had read valid data. This is solved by
5168 making cfg_getline check the buff that was returned from apr_fgets.
5169 If apr_fgets return APR_EOF, but there was data in the buf, then we
5170 return the buf, otherwise we return NULL.
5173 *) Piped logs work again in the 2.0 series.
5176 *) Restore functionality broken by the mod_rewrite security fix:
5177 rewrite map lookup keys and default values are now expanded
5178 so that the lookup can depend on the requested URI etc.
5179 PR #6671 [Tony Finch]
5181 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
5182 security bug in some mass virtual hosting configurations
5183 that can allow a remote attacker to retrieve some files
5184 on the system that should be inaccessible. [Tony Finch]
5186 *) Add a pool bucket type. This bucket is used for data allocated out
5187 of a pool. If the pool is cleaned before the bucket is destroyed, then
5188 the data is converted to a heap bucket, allowing it to survive the
5192 *) Add a flush bucket. This allows modules to signal that the filters
5193 should all flush whatever data they currently have. There is no way
5194 to actually force them to do this, so if a filter ignores this bucket,
5195 that's life, but at least we can try with this.
5198 *) Add an output filter for sub-requests. This filter just strips the
5199 EOS bucket so that we don't confuse the main request's core output
5200 filter by sending multiple EOS buckets. This change also makes sub
5201 requests start to send EOS buckets when they are finished.
5204 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
5205 makes ap_bucket_destroy a return void, which is okay because it
5206 used to always return APR_SUCCESS, and nobody ever checked its
5207 return value anyway.
5208 [Cliff Woolley <cliffwoolley yahoo.com>]
5210 *) Remove the index into the bucket-type table from the buckets
5211 structure. This has now been replaced with a pointer to the
5212 bucket_type. Also add some macros to test the bucket-type.
5215 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
5216 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
5217 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
5218 All _VAR_ flavors changes to _DATA to be absolutely clear.
5221 *) Add support for /, //, //servername and //server/sharename
5222 parsing of <Directory> blocks under Win32 and OS2.
5223 [Tim Costello, William Rowe, Brian Harvard]
5225 *) Remove the function pointers from the ap_bucket type. They have been
5226 replaced with a global table. Modules are allowed to register bucket
5227 types and use then use those buckets.
5230 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
5231 once we finish writing the request body to the cgi child process;
5232 otherwise, the client doesn't hit EOF on stdin. Small request bodies
5233 worked without this change (for reasons I don't understand), but large
5234 ones didn't. [Jeff Trawick]
5236 *) Remove file bucket specific information from the ap_bucket type.
5237 This has been moved to a file_bucket specific type that hangs off
5238 the data pointer in the ap_bucket type.
5241 *) Input filtering now has a third argument. This is the amount of data
5242 to read from lower filters. This argument can be -1, 0, or a positive
5243 number. -1 means give me all the data you have, I'll deal with it and
5244 let you know if I need more. 0 means give me one line and one line
5245 only. A positive number means I want no more than this much data.
5247 Currently, only 0 and a positive number are implemented. This allows
5248 us to remove the remaining field from the conn_rec structure, which
5252 *) Big cleanup of the input filtering. The goal is that http_filter
5253 understands two conditions, headers and body. It knows where it is
5254 based on c->remaining. If c->remaining is 0, then we are in headers,
5255 and http_filter returns a line at a time. If it is not 0, then we are
5256 in body, and http_filter returns raw data, but only up to c->remaining
5257 bytes. It can return less, but never more.
5258 [Greg Ames, Ryan Bloom, Jeff Trawick]
5260 *) mod_cgi: Write all of the request body to the child, not just what
5261 the kernel would accept on the first write. [Jeff Trawick]
5263 *) Back out the change that moved the brigade from the core_output_filters
5264 ctx to the conn_rec. Since all requests over a given connection
5265 go through the same core_output_filter, the ctx pointer has the
5269 *) Fix another bug in the send_the_file() read/write loop. A partial
5270 send by apr_send would cause unsent data in the read buffer to
5271 get clobbered. Complete making send_the_file handle partial
5272 writes to the network.
5275 *) Fix a couple of type fixes to allow compilation on AIX again
5276 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
5278 *) Fix bug in send_the_file() which causes offset to be ignored
5279 if there are no headers to send.
5282 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
5283 filter. Useful for supporting Windows 9* with a binary
5284 compiled on Windows NT.
5287 Changes with Apache 2.0a7
5289 *) Reimplement core_output_filter to buffer/save bucket brigades
5290 across multiple calls to the core_filter. The brigade will be
5291 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
5292 thresholds are hit or the EOS bucket is received.
5295 *) Create experimental filter (buffer_filter) that coalesces bytes
5296 into one large buffer before invoking the next filter in the
5297 chain. This filter is particularly useful with the current
5298 implementation of mod_autoindex when it inserted above the
5299 chunk_filter. mod_autoindex generates a lot of brigades that
5300 containing buckets holding just a few bytes each. The
5301 buffer_filter coalesces these buckets into a single large bucket.
5304 *) Add apr_sendfile() support into the core_output_filter.
5307 *) Add apr_sendv() support into the core_output_filter.
5310 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
5311 [Mike Abbott <mja sgi.com>]
5313 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
5314 make much sense, because Apache uses buckets instead of BUFFs now.
5317 *) send_the_file now falls back to a read/write loop on platforms that
5318 do not have sendfile.
5319 [Ryan Bloom and Brian Havard]
5321 *) Install apachectl correctly, and substitute the proper values so
5322 that it works again. [Ryan Bloom]
5324 *) Better(??) handle platforms that lack sendfile().
5327 *) APR now has UUID generation/formatting/parsing support.
5330 *) Begin the http_filter. This is an input filter that understands
5331 the absolute basic amount required to parse an HTTP Request. The
5332 goal is to be able to split headers from request body before passing
5333 the data back to the other filters.
5336 *) Bring forward from 1.3.13 the config directory implementation
5339 *) install apxs if it is created
5342 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
5343 conversions. [William Rowe]
5345 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
5346 ap_add_output_filter(). [Jeff Trawick]
5348 *) Multiple build and configuration fixes
5351 -add datadir and localstatedir substitutions
5353 -fix logfilename misspelling
5354 -fix evaluation of installation dir variables and
5355 -replace $foobar by $(foobar) to be usefull in the makefile
5359 -add rules for cross-compiling in rules.mk. Okay, rule to check for
5360 $CC_FOR_BUILD is still missing
5361 -use CHECK_TOOL instead of CHECK_PROG for ranlib
5362 -add missing "AR=@AR@" to severaly Makefile.in's
5363 -cache result for "struct rlimit"
5364 -compile all helper programs with native and cross compiler
5365 and use the native version to generate header file
5366 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5368 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
5370 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5372 *) Fix a bug where a client which only sends \n to delimit header
5373 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
5374 message. Start working on ebcdic co-existance with input
5376 [William Rowe, Greg Ames]
5378 *) If mod_so is enabled in the server always create libexec, even
5379 if there are no modules installed in this directory. This is a
5380 requirement for APXS to work correctly.
5383 *) Connection oriented output filters are now stored in the
5384 conn_rec instead of the request_rec. This allows us to add the
5385 output filter in the pre-connection phase instead of the
5386 post_read_request phase, which keeps us from trying to write an
5387 error page before we have a filter to write to the network.
5388 [Ryan Bloom, Jeff Trawick, and Greg Ames]
5390 *) Cleaning up an mmap bucket no longer deletes the mmap. An
5391 mmap can be used across multiple buckets (default_handler with
5392 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
5393 the mmap itself can't be associated with the bucket.
5396 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
5399 *) Radical surgery to improve mod_isapi support under Win32.
5400 Includes a number of newer ServerSupportFunction calls, support
5401 for ReadClient (in order to retrieve POSTs greater than 48KB),
5402 and general bug fixes to more reliably load ISAPI .dll's and
5403 prevent leaking handle resources. Note: There are still
5404 discrepancies between IIS's and Apache's ServerVariables, and
5405 async calls are still not supported. Additional warnings are
5406 logged to facilitate debugging of unsupported ISAPI calls.
5409 *) Add input filtering to Apache. The basic idea for the input
5410 filters is the same as the ideas for output filters. The biggest
5411 difference is that instead of calling ap_pass_brigade, ap_get_brigade
5412 should be called, and the order of execution for the filter itself is
5413 different. When writing an output filter, a brigade is passed in,
5414 and filters operate directly on that brigade, when done, they call
5415 ap_pass_brigade. Input filters are the exact opposite. Because input
5416 is not a push operation, filters first call ap_get_brigade. When this
5417 function returns, the input filter will be left with a valid brigade.
5418 The input filter should then operate on the brigade, and return.
5421 *) Fix building on BSD/OS using its native make. The build system
5422 falls back to the BSD .include directive on that host platform.
5425 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
5426 SHA1 and plaintext password encodings. Make feature tests a
5427 bit more flexible. [William Rowe]
5429 *) Charset translation: mod_charset_lite handles output content
5430 translation in a filter. mod_charset_lite no longer ignores
5431 subrequests. A bunch of cruft related to BUFF's support for
5432 translating request and response bodies was removed.
5435 *) Move the addition of the CORE filter to the post_read_request
5436 hook in http_core.c. This removes the need to add the filter in
5437 multiple places and allows for an SSL module to be added much
5438 simpler. [Ryan Bloom]
5440 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
5441 Fix a security problem that affects certain configurations of
5442 mod_rewrite. If the result of a RewriteRule is a filename that
5443 contains expansion specifiers, especially regexp backreferences
5444 $0..$9 and %0..%9, then it may be possible for an attacker to
5445 access any file on the web server. [Tony Finch]
5447 *) Fix a bug where errors that are detected during early request parsing
5448 don't produce visible HTTP error messages at the browser, because
5449 the core_filter wasn't present. [Greg Ames]
5451 *) Provide apr_socklen_t as a portability aid.
5452 [Victor J. Orlikowski]
5454 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
5455 as well as a comment arg to the add, adduser and update cmds.
5456 update allows the user to clear or preserve pw/groups/comment.
5457 Fixed a bug in dbmmanage that prevented the check option from
5458 parsing a password followed by :group... text. Corrected the
5459 seed calcualation for Win32 systems, and added -lsdbm support.
5462 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
5465 *) Avoid a segfault when parsing .htaccess files. An
5466 uninitialized tree pointer was passed to ap_build_config().
5469 *) Change the way that inet_addr & inet_network are checked for
5470 in APR's configure process to allow BeOS BONE to correctly
5471 find them. With this change BeOS BONE now builds from source
5472 with no problems. [David Reid]
5474 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
5475 the end of the parameters to execve() was stored in the wrong
5476 location, overlaying the storage beyond the newargs[] array and
5477 also passing uninitialized storage to execve(), which would
5478 sometimes fail with EFAULT. [Jeff Trawick]
5480 *) Fix a bug parsing configuration file containers. With a sequence
5481 like this in the config file
5483 <IfModule mod_kilroy.c>
5486 <IfModule mod_lovejoy.c>
5491 the second container would be terminated at the blank line due to
5492 sediment in the buffer from reading the prior </IfModule> and an
5493 error message would be generated for the real </IfModule> for the
5494 second container. Also due to this problem, any two characters
5495 could be used for "</" in the close of a container.
5498 *) ap_add_filter prototype changed to remove the ctx pointer. The
5499 pointer still remains in the filter structure, but it can not be
5500 a part of the ap_add_filter prototype. The reason is that when
5501 the core uses AddFilter to add a filter to the stack it doesn't
5502 know how to allocate the ctx pointer, or even how much memory should
5503 be allocated. The filters will have to be responsible for allocating
5504 the ctx memory when they need it.
5507 *) Add an AddFilter directive. This directive takes a list of filters
5508 that should be activated for the requested resource.
5511 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
5512 some other platforms). [Jeff Trawick]
5514 *) Modify mod_include to be a filter. Currently, it has only been tested
5515 on actual files, but it should work for CGI scripts too.
5518 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
5519 writes. apr_flush() for Unix: handle interrupted writes.
5522 *) NameVirtualHost can now take "*" as an argument instead of
5523 an IP address. This allows you to create a purely name-based
5524 virtual hosting server that does not have any IP addresses in
5525 the configuration file and which ignores the local address
5526 of any connections. PR #5595, PR #4455 [Tony Finch]
5528 *) Fix some compile warnings in mod_mmap_static.c
5529 [Mike Abbott <mja sgi.com>]
5531 *) Fix chunking problem with CGI scripts. The general problem was that
5532 the CGI modules were adding an EOS bucket and then the core added an
5533 EOS bucket. The chunking filter finalizes the chunked response when it
5534 encounters an EOS bucket. Because two EOS buckets were sent, we
5535 finalized the response twice. The fix is to make sure we only send one
5536 EOS, by utilizing a flag in the request_rec.
5539 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
5540 and Win32. Previously, the first read from an apr_file_t set up via
5541 apr_put_os_file() would return a '\0'. [Jeff Trawick]
5543 *) Mod_cgid now creates a single element bucket brigade, with a pipe
5544 bucket, instead of using BUFF's and ap_r*.
5547 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
5548 [Mike Abbott <mja sgi.com>]
5550 *) Remove ap_bopenf from buff code. This required modifying the file_cache
5551 code to use APR file's directly instead of going through BUFFs.
5554 *) Fix compile break on some platforms for mod_mime_magic.c
5555 [John K. Sterling <sterling covalent.net>]
5557 *) Fix merging of AddDefaultCharset directive.
5558 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
5560 *) Minor revamp of the rlimit sections of code. We now test
5561 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
5562 is now "available" even if the platform doesn't support
5563 the rlimit family (it's just a noop though). [Jim Jagielski]
5565 *) Migrate the pre-selection of which MPM to use for specific
5566 platforms to hints.m4, which contains (or should contain)
5567 all platform specific "hints". [Jim Jagielski]
5569 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
5572 *) Add tables with non-string/binary values to APR.
5575 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
5578 *) Update PCRE to version 3.2. [Ryan Bloom]
5580 *) Change the way buckets' destroy functions are called so that
5581 they can be more directly used when changing the type of a
5582 bucket in place. [Tony Finch]
5584 *) Add generic support for reference-counting the resources used by
5585 buckets, and alter the HEAP and MMAP buckets to use it. Change
5586 the way buckets are initialised to support changing the type of
5587 buckets in place, and use it when setting aside TRANSIENT buckets.
5588 Change the implementation of TRANSIENT buckets so that it can be
5589 mostly shared with IMMORTAL buckets, which are now implemented.
5592 Changes with Apache 2.0a6
5594 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
5596 *) Add a chunking filter to Apache. This brings us one step closer
5597 to removing BUFF. [Ryan Bloom]
5599 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
5600 added to the stack is the last filter to be called. [Ryan Bloom]
5602 *) Apache 2.0 has been completely documented using Scandoc. The
5603 docs can be generated by running 'make docs'. [Ryan Bloom]
5605 *) Add filtered I/O to Apache. This is based on bucket brigades,
5606 Currently the buckets still use BUFF under the covers, but that
5607 should change quickly. The only currently written filter is the
5608 core filter which just calls ap_bwrite. [The Apache Group]
5610 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
5611 built with thread support. [Jeff Trawick]
5613 *) Abort configuration if --with-layout was specified and there's
5614 no layout definition file. [Ken Coar]
5616 *) Add support for '--with-port=n' option to configure. [Ken Coar]
5618 *) Add support for extension methods for the Allow response header
5619 field, and an API routine for accessing r->allowed and the
5620 list of extension methods in a unified manner. [Ken Coar]
5622 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5623 [Rob Simonson <simo us.ibm.com>]
5625 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5626 APACHE_XLATE builds. [Jeff Trawick]
5628 *) A configuration file parsing problem was fixed. When the
5629 configuration file started with an IfModule/IfDefine container,
5630 only the last statement in the container would be retained.
5633 Changes with Apache 2.0a5
5635 *) Perchild is serving pages after passing them to different child
5636 processes. There are still a lot of bugs, but this does work. I
5637 have made requests against the same installation of Apache, and had
5638 different servers use different user IDs to serve the responses.
5639 This change moves to using socketpair instead of an AF_UNIX socket.
5642 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5643 It can't seem to pass between child processes yet, but I think we
5644 are closer now than before. This moves us back to using Unix
5645 Domain Sockets. [Ryan Bloom]
5647 *) libapr functions and types renamed with apr_ prefix.
5648 #include "apr_compat.h" for 1.3.x backwards compat
5651 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5652 return the right information on the local socket address.
5653 [Gregory Nicholls <gnicholls level8.com>]
5655 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5656 [Gregory Nicholls <gnicholls level8.com>]
5658 *) Add an option to not detach from the controlling terminal without
5659 going into single process mode. This allows for much easier
5660 debugging of the process startup code. [Ryan Bloom]
5662 *) ab: don't use perror() to report the failure of an APR function.
5665 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5666 scoreboard on graceful restarts.
5669 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5670 An invalid ap_proc_t was passed to ap_create_process().
5673 *) Allow modules to register filters. Those filters are still
5674 never called, but this is a step in the right direction.
5675 [Ryan Bloom and Greg Stein]
5677 *) Register the mod_cgid daemon process for cleanup so that it is
5678 killed at termination if it does not die when the parent gets
5679 SIGTERM. This change is to fix occasional problems where the
5680 process stays around. Bugs in similar logic in mod_rewrite and
5681 mod_include were also fixed. [Jeff Trawick]
5683 *) Fix a bug in the time handling. Basically, we were imploding a time
5684 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5685 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5686 uses those two fields to adjust the time value. Because of the HTTP
5687 spec, both of those values can be zero'ed out safely. This fixes
5688 the bug correctly. [Ryan Bloom]
5690 *) Fix a couple of place in the Windows code where the wrong error
5691 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
5693 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5695 *) Added the APR_EOL_STR macro for platform dependent differences in
5696 logfiles and other raw text (such as all APR files). Fixes logfiles
5697 not terminated with cr/lf sequences in Win32. [William Rowe]
5699 *) Move all strings functions in APR to src/lib/apr/strings and create
5700 apr_strings.h for the prototypes. [Ryan Bloom]
5702 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5703 to repeat the syscall until we stop getting EINTR. I noticed a
5704 related problem at termination (SIGTERM) on FreeBSD when using
5705 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5706 implementation work properly with child init. Previously, ap_lock()
5707 was essentially a no-op because all children were using different
5708 locks and thus nobody ever blocked. [Jeff Trawick]
5710 *) The htdocs/ tree has been moved out of the CVS source tree into
5711 a separate area for easier development. This has NO EFFECT on
5712 end-users or Apache installations. [Ken Coar]
5714 *) Integrate the mod_dav module for WebDAV protocol handling. This
5715 adds the dav and dav_fs modules, the SDBM library, and additional
5716 XML handling utilities. [Greg Stein]
5718 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
5721 *) Update the lib/expat-lite/ library (bring forward changes from
5722 the Apache 1.3 repository). [Greg Stein]
5724 *) If sizeof(long long) == sizeof(long), then prefer long in APR
5725 configure.in. [Dave Hill <ddhill zk3.dec.com>]
5727 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
5728 machines where sendfile is detected, but nobody has written ap_sendfile.
5729 [Dave Hill <ddhill zk3.dec.com>]
5731 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
5733 *) ab would start up more connections than needed, then quit when the
5734 desired number were finished. Also fixed a logic error involving
5735 ab keepalives. [Victor J. Orlikowski]
5737 *) WinNT: Implement non-blocking pipes with timeouts to communicate
5738 with CGIs. Apache 2.0a4 had non-blocking pipes but without
5739 timeouts (i.e, if a timeout was specified, the pipe reverted to
5740 a full blocking pipe). Now the behaviour is more in line with
5741 Unix non-blocking pipes.
5744 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
5745 cache open file handles along with accept socket reuse enables
5746 Apache 2.0 to serve non-keepalive requests for static files at
5747 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
5748 and Apache 2.0 will serve almost 1200 rps on my system).
5751 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
5752 supports two config directives, mmapfile (same behavious as
5753 mod_mmap_static) and cachefile. Use the cachefile directive
5754 to cache open file handles. This directive only works on systems
5755 that have implemented the ap_sendfile API. cachefile works today
5756 on Windows NT, but has not been tested on any flavors of Unix.
5759 *) Cleanup the configuration. With the last few changes the
5760 configuration process automatically:
5761 inherits information about how to build from APR. Allowing
5762 APR to inform Apache that it should or should not use -ldl
5764 Detects which mod_cgi should be used mod_cgi or mod_cgid,
5765 based on the threading model
5767 Apache calls APR's configure process before finishing it's
5768 configuration processing, allowing for more information flow
5773 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
5774 with non-zero argument makes the socket non-blocking. BeOS and
5775 OS/2 already worked this way. [Jeff Trawick]
5777 *) ap_close() now calls ap_flush() for buffered files, so write
5778 operations work a whole lot better on buffered files.
5781 *) Fix error messages issued from MPMs which explain where to change
5782 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
5785 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
5786 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
5787 now the way that the blocking state of a pipe is manipulated.
5788 ap_block_pipe() is gone. [Jeff Trawick]
5790 *) Correct the problem where the only local host name that the IP stack
5791 can discover are 'undotted' private names. If no fully qualified
5792 domain name can be identified, the default ServerName will be set to
5793 the machine's IP address string. A warning is always provided if the
5794 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
5796 *) Repair problems with config file processing which caused segfault
5797 at init when virtual hosts were defined and which caused ServerName to
5798 be ignored when there was no valid DNS setup. [Jeff Trawick]
5800 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
5802 *) Add ap_sendfile implementation for AIX
5803 [Victor J. Orlikowski]
5805 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
5806 apr_network_io.h, and apr_thread_proc.h.
5807 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
5809 *) Bring the allocation and pool debugging code back into a working
5810 state. This will need to be tested as so far it's only been used on
5813 *) Change configuration command setup to be properly typesafe when in
5814 maintainer mode. Note that this requires a compiler that can initialise
5815 unions. [Ben Laurie]
5817 *) Turn on buffering for config file reads. Part of this was to
5818 repair buffered I/O support in Unix and implement buffered
5819 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
5821 *) Win32: Fix problem where UTC offset was not being set correctly
5822 in the access log. Problem reported on news group by Jerry Baker.
5825 *) Fix segfault when reporting this type of syntax error:
5826 "</container> without matching <container> section", where
5827 container is VirtualHost or Directory or whatever.
5830 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
5831 Prevent the source code for CGIs from being revealed when
5832 using mod_vhost_alias and the CGI directory is under the document root
5833 and a user makes a request like http://www.example.com//cgi-bin/cgi
5834 as reported in <news:960999105.344321 ernani.logica.co.uk>
5837 *) Add support for the new Beos NetwOrking Environment (BONE)
5840 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
5841 final input char is incomplete; ap_bwrite_xlate() now handles
5842 incomplete final input chars. [Jeff Trawick]
5844 *) Yet another update to saferead/halfduplex stuff -- need to ensure
5845 that a bhalfduplex call occurs before logging or else DNS and
5846 such can delay the last packet of the response. [Dean Gaudet]
5848 *) Some syscall reduction in APR on unix -- don't seek when setting
5849 up an mmap; and don't fcntl() more than once per socket.
5852 *) When mod_cgid is started as root, the cgi daemon now switches
5853 to the configured User/Group (like other httpd processes)
5854 instead of continuing as root. [Jeff Trawick]
5856 *) The prefork MPM now uses an APR lock for the accept() mutex.
5857 It has not been getting a lock at all recently. httpd -V now
5858 displays APR's selection of the lock mechanism instead of the
5859 symbols previously respected by prefork. [Jeff Trawick]
5861 *) Change the mmap() feature test to check only for existence.
5862 The previous check required features not used by Apache.
5865 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
5866 sometimes mangled. The len parm to accept() was not
5867 initialized, leading sometimes to an endless loop of failed
5868 accept() calls on OS/390 and anywhere else that failed the call
5869 if the len was negative. Use <sys/un.h> for struct sockaddr_un
5870 instead of declaring it ourselves to fix a compilation problem
5871 on Solaris. [Jeff Trawick]
5873 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
5875 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
5877 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
5879 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
5880 initialization if ALLOC_DEBUG is defined; no known symptom
5881 otherwise. [Jeff Trawick]
5883 *) Fix typo in configure script when checking for mod_so. bash
5884 doesn't seem to have a problem but /bin/sh on Solaris does.
5885 Symptom: "./configure: test: unknown operator =="
5888 *) Rebind the Win32 NT and 9x services control into the MPM.
5889 All console, WinNT SCM and Win9x pseudo-service control code is
5890 now wrapped within the WinNT MPM.
5893 *) Make a copy of getenv("PATH") before storing for later use. Some
5894 getenv() implementations use the same storage for successive calls.
5895 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
5897 *) Server Tokens work in 2.0 again. This also propogates the change
5898 to allow just the product name in the server string using
5902 Changes with Apache 2.0a4
5904 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
5905 won't need to call it. [Greg Ames, Jeff Trawick]
5907 *) Move pre_config hook call to between configuration read and config
5908 tree walk. This allows all modules to implement pre_config hooks
5909 and know that they will be called at an appropriate time.
5912 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
5915 *) Add pre-config hooks back to all modules.
5918 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
5919 ContentDigest enabled and we can't/don't mmap the file.
5922 *) We now report the correct line number for syntax errors in config
5923 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
5925 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
5926 related bugs, and changed shmem/locking to use apr API. Shared-mem
5927 is currently disabled, however, because of problems with graceful
5928 restarts. [Ronald Tschalär]
5930 *) Fix corruption of IFS variable in --with-module= handling.
5931 Depending on the user's shell or customization thereof, there
5932 would be errors generating ap_config_auto.h later in the configure
5933 procedure. [Jeff Trawick]
5935 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
5936 isn't used (as in 1.3), except that on Unix it is now logged via
5937 ap_log_rerror() instead of by the child having STDERR_FILENO refer
5938 to the error log. [Greg Ames, Jeff Trawick]
5940 *) Add '-D' argument processing for run time configuration defines.
5943 *) Organize http_main.c as independent code, such that no code or
5944 global data is exported from it. WIN32 will dynamically link it
5945 to the server core, so this will prevent mutual dependency.
5948 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
5949 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
5952 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
5953 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
5955 *) Add mod_charset_lite for configuring character set translation.
5958 *) Add '-n' option to htpasswd to make it print its user:pw record
5959 on stdout rather than having to frob a text file. [Ken Coar]
5961 *) Fix saferead. Basically, we flush the output buffer if a read on the
5965 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
5966 a conversion is single-byte only. [Jeff Trawick]
5968 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
5969 the BeOS 5.0 documentation says that shutdown doesn't work yet.
5972 *) Fix some minor errors where pid was being manipulated as an int
5973 instead of the portable pid_t. [Roy Fielding]
5975 *) Fix some error log prints that were printing the pointer to a
5976 structure rather than the pid within the structure.
5977 [Jeff Trawick, Roy Fielding]
5979 *) ab: Fix a command-line processing bug; track bad headers in
5980 err_response; support reading headers up to 2K.
5981 [Ask Bjoern Hansen <ask valueclick.com>]
5983 *) Fix ap_resolve_env() so that it handles new function added in a prior
5984 alpha (see "Added the capability to do ${ENVVAR} constructs in the
5985 config file.") as well as the constructs used by mod_rewrite.
5986 [Paul Reder <rederpj raleigh.ibm.com>]
5988 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
5990 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
5991 APR to perform translation, instead of accessing the hard-coded tables
5992 in 1.3's ebcdic.c. [Jeff Trawick]
5994 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
5997 *) Add the ability to hook into the config file reading phase. Basically
5998 if a directive is specified EXEC_ON_READ, then when that directive is
5999 read from the config file, the assocaited function is executed. This
6000 should only be used for those directives that must muck with HOW the
6001 server INTERPRETS the config. This should not be used for directives
6002 that re-order or replace items in the config tree. Those changes should
6003 be made in the pre-config step.
6006 *) Add mod_example to the build system.
6009 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
6010 byte character sets. [Jeff Trawick]
6012 *) Pick up various EBCDIC fixes from 1.3 (from Martin
6013 Kraemer and Oliver Reh originally according to the change log).
6016 *) Fix a couple of problems in RFC1413 support (controlled by the
6017 IdentityCheck directive). Apache did not build the request string
6018 properly and more importantly Apache would loop forever if the
6019 would-be ident server dropped the connection before sending a
6020 properly terminated response. [Jeff Trawick]
6022 *) apxs works in 2.0.
6025 *) Reliable piped logs work in 2.0.
6028 *) Introduce a hash table implementation into APR to be used for
6029 replacing tables and other random data structures in Apache.
6032 *) Add some more error reporting to htpasswd in the case of problems
6033 generating or accessing the temporary file. Also, pass in a
6034 buffer if the implementation knows how to use it (i.e., if L_tmpnam
6035 is defined). [Ken Coar]
6037 *) Configure creates config.nice now containing your configure
6038 options. Syntax: ./config.nice [--more-options]
6041 *) Fix various return code problems in APR on Win32. For most of
6042 these, APR was returning APR_EEXIST instead of GetLastError()/
6043 WSAGetLastError(). [Jeff Trawick]
6045 *) Make piped logs work again in version 2.0
6048 *) Add VPATH support to UNIX build system of Apache and APR.
6051 *) Fix ap_tokenize_to_argv to respect the const arguments that are
6055 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
6056 Patch submitted to author.
6059 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
6060 /sbin in PATH on FreeBSD (all submitted to rse previously)
6063 *) Fix building Pthread-based MPMs on OpenBSD
6064 [Sascha Schumann] PR#26
6066 *) Fix ap_readdir() problem on systems where d_name[] field in
6067 struct dirent is declared with only one byte. (This problem only
6068 affected multithreaded builds.) This caused a segfault during
6069 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
6070 least). [Jeff Trawick]
6072 *) Fix some make-portability problems on at least Tru64, Irix
6074 [Sascha Schumann] PR#18, PR#39
6076 *) Add ap_sigwait() to support old-style sigwait() on systems
6077 like OS/390 and UnixWare.
6080 *) Add POSIX-thread flags for more platforms.
6083 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
6084 (on Unix, at least) to handle resolver errors. Fix a bug in
6085 the definition of APR_ENOMEM so that ap_strerror() can spit
6086 out the correct error message for it.
6089 Changes with Apache 2.0a3
6091 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
6094 *) API: *HOOK* macros now have an AP_ prefix
6097 *) Win32: Eliminate redundant calls to initialize winsock.
6098 [Tim Costello <timcostello ozemail.com.au>]
6100 *) Fix bugs initializing ungetchar for pipes.
6101 [Chia-liang Kao <clkao CirX.ORG>]
6103 *) The ab program in the src/support directory is now portable using
6107 *) Support directory is being compiled when the server is built
6110 *) The configure option --with-program-name has been added to allow
6111 developers to rename the executable at configure time. This also
6112 changes the name of the config files to match the executable's name.
6115 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
6116 containing version numbers. [Martin Pool]
6118 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
6119 Unix; access_log and error_log now created with these perms; non-
6120 Unix is unaffected [Jeff Trawick]
6122 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
6123 Replaced more magic numbers with MD5_DIGESTSIZE.
6124 [William Rowe, Roy Fielding]
6126 *) Win32: Get mod_auth_digest compiling and added to the Windows
6127 build environment. Not tested and I'd be suprised if it
6128 actually works. [Bill Stoddard]
6130 *) Revamp the Win32 make environment. Makefiles have been removed and
6131 Apache.dsw created to bring together all the pieces. Create new file
6132 os/win32/BaseAddr.ref to define module base addresses (to prevent
6133 dll relocation at start-up).
6134 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
6136 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
6137 of the \015, \012, and \015\012 constants with macros.
6140 *) Add ap_xlate_open() et al for translation of text between different
6141 character sets. The initial implementation requires iconv().
6144 *) More FAQs and answers from comp.infosystems.www.servers.unix.
6145 [Joshua Slive <slive finance.commerce.ubc.ca>]
6147 *) CGI output is being timed out now.
6150 *) Fix the problem with dieing quietly. dupfile now takes a pool which
6151 is used by the new apr file. There is no reason to create a new file
6152 with the same lifetime as the original file.
6155 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
6156 module base addresses. This will help shooting seg faults
6157 in the field. [William Rowe <wrowe lnd.com>]
6159 *) Update Apache on Windows documentation. Add new document
6160 describing how to compile Apache on Windows.
6161 [William Rowe <wrowe lnd.com>]
6163 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
6164 microseconds instead of seconds. Some storage leaks and other
6165 minor bugs in related code were fixed. [Jeff Trawick]
6167 *) Win32: First cut at getting mod_isapi working under 2.0
6168 [William Rowe <wrowe lnd.com>]
6170 *) First stab at getting mod_auth_digest working under 2.0
6171 quick change summary:
6172 - moved the random byte generation (ap_generate_random_bytes) into APR
6173 - now uses ap_time_t
6174 - compiles and runs on linux
6176 [Brian Martin <bmartin penguincomputing.com>]
6178 *) Win32: Move the space stripping of physical service names
6179 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
6180 unresolved symbol. Add dependency checking to the
6181 CreateService call to ensure TCPIP and AFP (winsock) is started
6183 [William Rowe <wrowe lnd.com>]
6185 *) Win32: Add code to perform latebinding on functions that may
6186 not exist on all levels of Windows where Apache runs. This
6187 is needed to allow Apache to start-up on Win95/98. All calls
6188 to non portable functions should be protected with
6189 ap_oslevel checks to prevent runtime segfaults.
6190 [William Rowe <wrowe lnd.com>]
6192 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
6194 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
6196 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
6197 This addresses PR 1623. Still need to address timing out runaway
6198 CGI scripts. [Bill Stoddard]
6200 *) Win32: Make ap_stat Windows 95/98 friendly
6201 [William Rowe <wrowe lnd.com>]
6203 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
6204 always fail. Need to initialise the dwOSVersionInfoSize member of the
6205 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
6208 The patch also enhances ap_get_oslevel (and the associated enum) to
6209 handle selected service packs for NT4, and adds recognition for
6210 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
6211 we can use ReadFileScatter and WriteFileGather in readwrite.c.
6212 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
6214 *) Get mod_rewrite building and running, and mod_status building for Win NT
6215 [Allan Edwards <ake raleigh.ibm.com>]
6217 *) Patch to port mod_auth_db to the 2.0 api and also to support
6218 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
6219 2.7.7. It should work with version 1 as well but I haven't tested it.
6220 [Brian Martin <bmartin penguincomputing.com>]
6222 *) Get APR DSO code working under Windows. Includes cross platform
6224 [<Tim.Costello BTFinancialgroup.com>]
6226 *) Fix some of the Windows APR time functions.
6229 *) FAQ changes related to tidying up historical documents on the web site.
6230 [Joshua Slive <slive finance.commerce.ubc.ca>]
6232 *) Move Windows DSO code into APR.
6235 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
6236 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
6237 at build time. At this point, the server will not compile on Windows because
6238 of the recent DSO commits. Fixing those next.
6239 [Bill Rowe & Bill Stoddard]
6241 *) Added error checking for file I/O APR routines.
6242 [Jon Travis <jtravis covalent.net>]
6244 *) APR: Don't use the values of resolver error codes for the
6245 corresponding APR error codes. On Unix and Win32, return the
6246 proper APR error code after a resolver error. [Jeff Trawick]
6248 Changes with Apache 2.0a2
6250 *) Renamed the executable back to httpd on all platforms other
6254 *) Allow BeOS to survive restarts, log properly and a few
6255 small things it had problems with due to the way it setup
6256 users and groups. [David Reid]
6258 *) Get mod_rewrite working with APR locks
6259 [Paul Reder <rederpj raleigh.ibm.com>]
6261 *) Actually remove the sempahore when the lock cleanup routine
6262 is called on BeOS. [David Reid]
6264 *) Clear hook registrations between reads of the config file.
6265 When DSOs are unloaded and re-loaded the old hook pointers may
6266 no longer be valid. This fix eliminates potential segfaults.
6267 [Allan Edwards <ake raleigh.ibm.com>]
6269 *) Fix a problem with Sigfunc not being defined or bypassed
6270 if sigaction() wasn't found. [Jim Jagielski]
6272 *) Fix the locking mechanism on BSD variants. They now use fcntl
6273 locks. This allows the server to start and serve pages.
6276 *) First cut at getting the Win32 installer to work
6277 [William Rowe <wrowe lnd.com>]
6279 *) Get htpasswd compiling under Windows
6280 [William Rowe <wrowe lnd.com>]
6282 *) Change the log message for a bind() failure to show the
6283 interface and port number. [Jeff Trawick]
6285 *) Import the documentation from 1.3.12 and bring parts of it
6286 up-to-date with respect to the changes that have occurred
6290 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
6291 now logged correctly on BeOS.
6294 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
6295 Makefile.win includes the same user interface as the old
6297 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
6299 *) Win32 exec now uses COMSPEC environment string for command
6300 shell path resolution.
6301 [William Rowe <wrowe lnd.com>] PR#3715
6303 *) Win32: ap_connect() was not returning correct error condition
6305 [Allen Prescott <allen clanprescott.com>]
6307 *) Win32: ap_open() was broken on Win9x because an NT-specific
6308 flag was passed to CreateFile. ap_puts() added an unnecessary
6310 [Jeff Trawick <trawick us.ibm.com>]
6312 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
6313 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
6314 confusing ee/et name and made all extensions language/dialect
6315 rather than country reflecting. Changed example files to
6316 explicit reflect the ISO charset and added a few common
6317 ones to the example config [dirkx]
6319 *) Extend external module capability. To use this, you call
6320 configure with --with-module=path/to/mod1,path/to/mod2,etc.
6323 *) Backported the various "default charset" fixes from 1.3.12,
6324 including the AddDefaultCharset directive. [Jim Jagielski]
6326 *) Added the capability to do ${ENVVAR} constructs in the
6327 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
6328 it does this on a line by line basis; i.e. if the envvar
6329 expands to something with spaces you have to protect it
6330 by adding quotes around it (Unless of course you expect it
6331 to contains more than one argument. Alternatively you
6332 can compile it on a per token basis; which is what people
6333 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
6334 hampers fancier hacks.
6335 [Dirk-Willem van Gulik]
6337 *) Changed the 'ErrorDocument' syntax in that it NO longer
6338 supports the asymetric
6340 ErrorDocument 301 "Some message
6342 Note the opening " quote, without a closing quote. It now
6343 has either the following syntaxes
6345 ErrorDocument XXX /local/uri
6346 ErrorDocument XXX http://valid/url
6347 ErrorDocument XXX "Some Message"
6349 The recognition heuristic is: if it has a space it
6350 is a message. If it has no spaces and starts with a /
6351 or is a valid URL then treat it that way. Otherwise it
6352 is assumed to be a message.
6354 This breaks backward compatibility but makes live a hell
6355 of a lot easier for GUI's and config file parsers.
6356 [Dirk-Willem van Gulik]
6358 *) Changed 'CacheNegotiatedDocs' from its present/not-present
6359 syntax into a 'on' or 'off' syntax. As it currently is the
6360 only non nesting token which uses NO_ARGS and thus is an
6361 absolute pain for any config interface automation. This
6362 breaks backward compatibility. [Dirk-Willem van Gulik]
6364 *) Add ability to add external modules to the build process. This is
6365 done with --with-module=/path/to/module. Modules can only be added
6366 as static modules at this point.
6369 Changes with Apache 2.0a1
6371 *) Fix FreeBSD 3.3 core dump.
6372 Basically, ap_initialize() needs to get called before
6373 create_process(), since create_process() passes op_on structure
6374 to semop() to get a lock, but op_on isn't initialized until
6375 ap_initialize() calls setup_lock(). Here is a slight
6376 rearrangement to main() which calls ap_initialize() earlier...
6377 [Jeff Trawick <trawick us.ibm.com>]
6379 *) Enable Apache to use sendfile/TransmitFile API
6380 [Bill Stoddard, David Reid, Paul Reder]
6382 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
6386 *) Make file I/O and network I/O writev/sendv APIs consistent.
6387 Eliminate use of ap_iovec_t and use Posix struct iovec.
6388 Use seperate variable on ap_writev to set the number of iovecs
6389 passed in and number of bytes written.
6392 *) Adapt file iol to use APR functions. Replaced ap_open_file()
6393 with ap_create_file_iol(). ap_create_file_iol() requires that
6394 the file be opened prior to the call using ap_open().
6397 *) Port mod_include and mod_cgi to 2.0
6398 [Paul Reder, Bill Stoddard]
6400 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
6401 bytes_read/bytes_written is always valid (never -1). Plus
6402 some fixes to buff.c to correct problems introduced by the
6403 errno => ap_status_t changes a while back. Plus a fix to
6404 chunked encoding introduced right at the beginning of 2.0.
6407 *) Revamped UNIX build system to use autoconf and libtool.
6408 [Manoj Kasichainula, Sascha Schumann]
6410 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
6412 *) SECURITY: More rigorous checking of Host: headers to fix security
6413 problems with mass name-based virtual hosting (whether using mod_rewrite
6414 or mod_vhost_alias).
6415 [Ben Hyde, Tony Finch]
6417 *) Add back support for UseCanonicalName in <Directory> containers.
6418 [Manoj Kasichainula]
6420 *) Added APLOG_STARTUP log type. This allows us to write an error
6421 message without any of the date and time information. As a part
6422 of this change, I also removed all of the calls to fprintf(stderr
6423 and replaced them with calls to ap_log_error using APLOG_STARTUP
6424 writing to stderr is no longer portable, because we don't direct
6425 stderr to the error log on all platforms.
6428 *) Convert error logging functions to take errno as an argument.
6429 This makes our error logs more portable, because some Windows API's
6430 don't set errno. This change allows us to still output a valid
6431 message on all of our platforms.
6434 *) mod_mime_magic runs in 2.0-dev now.
6435 [Paul Reder <rederpj raleigh.ibm.com>]
6437 *) sendfile has been added to APR.
6438 [John Zedlewski <zedlwski Princeton.EDU>]
6440 *) buff.c has been converted to no longer use errno.
6441 [Manoj Kasichainula]
6443 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
6444 interface adaption to APR functions did it. [Martin Kraemer]
6446 *) Support DSOs properly on 32-bit HP-UX 11.0
6447 [Dilip Khandekar <dilip cup.hp.com>]
6449 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
6450 [Ralf S. Engelschall]
6452 *) Cleaned APR build environment integration and bootstrap APR
6453 automatically for developers from src/Configure.
6454 [Ralf S. Engelschall]
6456 *) Fixed building of src/support/htpasswd.c
6457 [Ralf S. Engelschall]
6459 *) When generating the Location: header, mod_speling forgot
6460 to escape the spelling-fixed uri. (Forw-Port from 1.3)
6463 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
6465 *) Change all pools to APR contexts. This is the first step to
6466 incorporating APR into Apache. [Ryan Bloom]
6468 *) Move "handler not found" warning message to below the check
6469 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
6470 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
6472 *) Support line-continuation feature in config.option file and
6473 allow the loading of multiple option sections at once via
6474 ``--with-option=<section1>,<section2>,...''
6475 [Ralf S. Engelschall]
6477 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
6479 Changes with Apache MPM
6481 *) Use asynchronous AcceptEx() and a completion port to accept and
6482 dispatch connections to threads in Windows NT/2000.
6485 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
6488 *) Implement the APACI --with-option facility
6489 (per default used the config.option file).
6490 [Ralf S. Engelschall]
6492 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
6494 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
6495 Replace pre_connection module call with a register_hook call and
6496 implement pre_connection as a hook. The intent is that these hooks will
6497 be extended to allow Apache to be multi-protocol, and also to allow the
6498 calling order to be specified on a per-hook/per-module basis.
6501 *) Implement mpm_* methods as "modules". Each method gets its own
6502 subdir in src/modules (eg: src/modules/prefork). Selection
6503 of method uses Rule MPM_METHOD. [Jim Jagielski]
6505 *) Port the hybrid server from the apache-apr repository as
6506 mpm_mpmt_pthread. [Manoj Kasichainula]
6508 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
6509 amongst the unix MPMs.
6511 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
6512 signal handling for the new world order. [Dean Gaudet]
6514 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
6515 of alloc.c for now. [Dean Gaudet]
6517 *) Handle partial large writes correctly. [Ben Laurie]
6519 *) Eliminate conn_rec's pointer to server. All it knows is the base server
6520 based on IP/port. [Ben Laurie]
6522 *) Port a bunch of modules to the new module structure.
6523 ["Michael H. Voase" <mvoase midcoast.com.au>]
6525 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
6527 *) Basic restructuring to introduce the MPM concept; includes various
6528 changes to the module API... better described by
6529 docs/initial_blurb.txt. [Dean Gaudet]
6531 Changes with Apache pthreads
6533 *) New buff option added: BO_TIMEOUT. It describes the timeout for
6534 buff operations (generally over a network).
6535 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
6537 *) Created http_accept abstraction. Added 4 new functions (not exported):
6538 init_accept(), begin_accepting_requests(), get_request(),
6539 stop_accepting_requests() [Bill Stoddard]
6541 *) Fix to ap_rprintf call that allows mod_info to work properly.
6542 [James Morris <jmorris intercode.com.au>]
6544 *) user and ap_auth_type fields were moved from connection_rec to
6545 request_rec. [Ryan Bloom]
6547 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
6548 needed in a threaded server.
6550 *) Initial pthread implementation from from Dean's apache-nspr code.
6551 [Bill Stoddard, Ryan Bloom]
6554 Changes with Apache 1.3.9
6556 *) Remove bogus error message when a redirect doesn't set Location.
6557 Instead, use an empty string to avoid coredump if the error message
6558 was supposed to include a location. [Roy Fielding]
6560 *) Don't allow configure to include mod_auth_digest unless it is
6561 explicitly requested, even if the user asked for all modules.
6564 *) Translate module names to dll names for OS/2 so that they are no more
6565 than 8 characters long and have an extension of "dll" instead of "so".
6568 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
6569 Fix test-compile check to check for randbyte instead of trand32.
6570 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
6571 and tweak to make Amaya happier. [Ronald Tschalär]
6573 *) Ensure that the installed expat include files are world readable,
6574 just like the other header files. [Martin Kraemer]
6576 *) Fixed generated AddModule adjustments in APACI's `configure' script
6577 in order to allow (new) modules like mod_vhost_alias to be handled
6578 correctly (which was touched by the adjustments for mod_alias).
6579 [Ralf S. Engelschall]
6581 *) For binary builds, add -R flag to apachectl to work around the lack of
6582 an absolute path to the ./libexec directory where the libhttp.ep file
6583 is needed for SHARED_CORE architectures. [Randy Terbush]
6585 *) WIN32: Create the CGI script process as DETACHED. This may solve the
6586 problem observed by some Win95/98 users where they get CGI script
6587 output sent to the console. [Bill Stoddard]
6589 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
6590 routines are now called ap_base64* and are 'plain' (i.e., no
6591 pool access or anything clever). Inside util.c the routines acting
6592 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
6593 The oddly named ap_uuencode(), ap_uudecode() are kept around for
6594 now but deprecated. [dirkx]
6596 *) Clean up the base64 and SHA1 additions and make sure they are
6597 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
6598 files. [Roy Fielding]
6600 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
6601 checking. Allow compiling on VS 6.0. [Randy Terbush]
6603 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
6605 *) Use TestCompile to search for the truerand library (rather than blindly
6606 assuming its existence). If it is not found, complain (but do not
6607 exit - yet). [Martin Kraemer]
6609 *) We forgot to add the new exported function names to
6610 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
6612 *) Add description of -T command-line option to usage().
6613 [Ralf S. Engelschall]
6615 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
6616 searched only AFTER libap has been searched, because libap needs
6617 some symbols from libos. [Martin Kraemer]
6619 *) Fix conflict with original mod_digest related to the symbol of the
6620 module dispatch list (which has to be unique for DSO and follow the
6621 usual conventions for the installation procedure).
6622 [Ralf S. Engelschall]
6624 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6625 for other platforms as well. [Martin Kraemer]
6627 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6628 types by AP_LONG and replace reference to renamed variable 'ubuf'
6629 by 'buffer'. [Martin Kraemer]
6631 Changes with Apache 1.3.8 [not released]
6633 *) Flush the output buffer immediately after sending an error or redirect
6634 response, since the result may be needed by the client to abort a
6635 long data transfer or restart a series of pipelined requests.
6636 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
6638 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6639 [Ian Turner <iant sequent.com>] PR#4735
6641 *) Local struct mmap in http_core.c conflicted with system structure
6642 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6644 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6645 [Ronald Tschalär <ronald innovation.ch>]
6647 *) Fix a memory leak where the module counts were getting messed
6648 up across restarts. [David Harris <dharris drh.net>]
6650 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6651 properly in mod_access.
6652 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
6654 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6655 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
6657 *) PORT: Support for compaq/tandem/com.
6658 [Michael Ottati <michael.ottati compaq.com>, dirkx]
6660 *) Added SHA1 password encryption support to easy migration from
6661 Netscape servers. See support/SHA1 for more information.
6662 Caused the separation of ap_md5.c into md5, sha1 and a general
6663 ap_checkpass.c with just a validate_passwd routine. Added a
6664 couple of flags to support/htpasswd. Some reuse of the to64()
6665 function; hence renamed to ap_to64().
6666 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
6668 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6669 with ASCII/EBCDIC conversions in "ident" query.
6670 [David McCreedy <McCreedy us.ibm.com>]
6672 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6673 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6674 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6676 *) Fix SIGSEGV on some systems because the Vary fix below included
6677 a call to table_do with a variable argument list that was not
6678 NULL terminated. Replaced with better implementation. [Roy Fielding]
6680 Changes with Apache 1.3.7 [not released]
6682 *) The "Vary" response header field is now sanitised right before
6683 the header is sent back to the client. Multiple "Vary" fields
6684 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6685 "Vary: host, negotiate, host, accept-language") are reduced to
6686 single instances. This is a better solution than the force-no-vary
6687 one (which is still valid for clients that can't cope with Vary
6688 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6690 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
6692 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6693 least on Linux and FreeBSD for now.
6696 *) Win32: More apache -k restart work. Restarts are now honored
6697 immediately and connections in the listen queue are -not- lost.
6698 This is made possible by the use of the WSADuplicateSocket()
6699 call. The listeners are opened in the parent, duplicated, then
6700 the duplicates are passed to the child. The original listen sockets
6701 are not closed by the parent across a restart, thus the listen queue
6703 [Bill Stoddard <stoddard raleigh.ibm.com>]
6705 *) Fix handling of case when a client has sent "Expect: 100-continue"
6706 and we are going to respond with an error, but get stuck waiting to
6707 discard the body in the pointless hope of preserving the connection.
6708 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
6710 *) Fix 'configure' to work correctly with SysV-based versions of
6711 'tr' (consistent with Configure's use as well). [Jim Jagielski]
6713 *) apxs: Add "-S var=val" option which allows for override of CFG_*
6714 built-in values. Add "-e" option which works like -i but doesn't
6715 install the DSO; useful for editing httpd.conf with apxs. Fix
6716 editing code so that multiple invocations of apxs -a will not
6717 create duplicate LoadModule/AddModule entries; apxs can now be
6718 used to re- enable/disable a module. [Wilfredo Sanchez]
6720 *) Win32: Update the server to use Winsock 2. Specifically, link with
6721 ws2_32.lib rather than wsock32.lib. This gives us access to
6722 WSADuplcateSocket() in addition to some other enhanced comm APIs.
6723 Win 95 users may need to update their TCP/IP stack to pick up
6724 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
6725 [Bill Stoddard <stoddard raleigh.ibm.com>]
6727 *) Win32: Redirect CGI script stderr (script debug info) into the
6728 error.log when CGI scripts fail. This makes Apache on Win32
6729 behave more like Unix.
6730 [Bill Stoddard <stoddard raleigh.ibm.com>]
6732 *) Fixed `httpd' usage display: -D was missing.
6733 [Ralf S. Engelschall] PR#4614
6735 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
6736 [Ralf S. Engelschall] PR#4561, PR#4562
6738 *) OS/2: Fix problem with accept lock semaphores where server would die with
6739 "OS2SEM: Error 105 getting accept lock. Exiting!"
6740 [Brian Havard] PR#4505
6742 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
6743 [Randy Terbush <randy covalent.net>]
6745 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
6746 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
6748 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
6749 command potentially _is_ GCC. [Ralf S. Engelschall]
6751 *) Fix apxs build issues on AIX
6752 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
6754 *) DocumentRoot Checking: Under previous versions, when Apache
6755 first started up, it used to do a stat of each DocumentRoot to
6756 see if it existed and was a directory. If not, then an error
6757 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
6758 does not exist, you will get error messages in error_log. If
6759 the '-t' command line option is used (to check the configuration)
6760 the check of DocumentRoot IS performed. An additional command
6761 line option, '-T', has been added if you want to avoid the
6762 DocumentRoot check even when checking the configuration.
6765 *) Win32: The query switch "apache -S" didn't exit after showing the
6766 vhost settings. That was inconsistent with the other query functions.
6767 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
6769 *) Win32: Changed behaviour of apache -k restart.
6770 Previously, the server would drain all connections in the stack's
6771 listen queue before honoring the restart. On a busy server, this
6772 could take hours. Now, a restart is honored almost immediately.
6773 All connections in Apache's queues are handled but connections in
6774 the stack's listen queue are discarded. Restart triggered by
6775 MaxRequestPerChild is unchanged.
6776 [Bill Stoddard <stoddard raleigh.ibm.com>]
6778 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
6779 the accept loop. Good for a 5% performance boost. Cleaned up
6780 parent/child process management code.
6781 [Bill Stoddard <stoddard raleigh.ibm.com>]
6783 *) Added ceiling on file size for memory mapped files.

6803 never accepted into any standard, and it opens up certain DoS
6804 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
6806 *) TestCompile updated. We can now run programs and output the
6807 results during the Configure process. [ Jim Jagielski]
6809 *) The source is now quad (long long) aware as needed. Specifically,
6810 the Configure process determines the correct size of off_t and
6811 *void. When the OS/platform/compiler supports quads, ap_snprintf()
6812 provides for the 'q' format qualifier (if quads are not available,
6813 'q' is silently "demoted" to long). [Jim Jagielski]
6815 *) When the username or password fed to htpasswd is too long, include the
6816 size limit in the error message. Also report illegal characters
6817 (currently only ':') in the username. Add the size restrictions

7092 a roughly 5 fold speed up. [Brian Havard]
7094 *) proxy ftp: instead of using the hardwired string "text/plain" as
7095 a fallback type for files served by the ftp proxy, use the
7096 ap_default_type() function to determine the configured type.
7097 This allows for special configurations like
7098 <Directory proxy:ftp://some.host>
7099 DefaultType gargle/blurb
7101 Additionally, add the Content-Encoding: header to FTP proxy replies
7102 when the encoding is defined (by the AddEncoding directive).
7103 Because it was missing, it was almost impossible to browse compressed
7104 files using the FTP proxy (works now perfectly in Communicator).
7105 The ftp proxy now also returns the Date: and Server: header lines (if not
7106 much else... This code is "somewhat" broken) like normal requests do.
7109 *) Be more smart in APACI's configure script when determining the UID/GID
7110 for User/Group directives and use the determined UID/GID to initialize

7155 work correctly on EBCDIC platforms.
7156 [Ronald Tschalär <ronald innovation.ch>] PR#3411
7158 *) WIN32: Binary installer now runs the configuration DLL before

7188 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
7189 because SPARCs have a small machine-specific maximum size for the Global
7190 Offset Table which is often exceeded when compiling one of the larger
7191 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977

7226 *) In configure, do not append the target name to the directory path if
7227 the path already contains "apache". [Ralf S. Engelschall]
7229 *) SIGPIPE is now ignored by the server core. The request write routines
7230 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
7231 correctly check for output errors and mark the connection as aborted.
7232 Replaced many direct (unchecked) calls to ap_b* routines with the
7233 analogous ap_r* calls. [Roy Fielding]
7235 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
7236 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
7237 Furthermore map lookups for non-existent keys are now cached as well.
7238 Additionally "txt" maps are now parsed with simple string functions
7239 instead of using ap_pregcomp(). As a side effect a bug that prevented
7240 the usage of keys containing the "," character was fixed.
7241 The changes drastically improve the performance when large rewrite maps
7243 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160

7251 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
7252 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
7254 *) Add %V to mod_log_config, this logs the hostname according to the

7291 *) Allow apache acting as a proxy server to relay the real
7292 reason of a failure to a client rather than the "internal
7293 server error" it does currently. The general exposure mechanism
7294 can be triggered by any module by setting the "verbose-error-to"

7309 is *not* given in the argument list; i.e., the logical negation
7310 of the <Limit> directive. This is particularly useful for controlling
7311 access on methods unknown to the Apache core, but perhaps known by
7312 some module or CGI script. [Roy Fielding, Tony Finch]
7314 *) Prevent apachectl from complaining if the PIDFILE exists but
7315 does not contain a process id, as might occur if the server is
7316 being rapidly restarted. [Wilfredo Sanchez]
7318 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
7320 *) Entity tag comparisons for If-Match and If-None-Match were not being
7321 performed correctly -- weak tags might cause false positives. Also,
7322 strong comparison wasn't properly enforced in all cases.
7323 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
7325 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
7328 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
7329 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
7331 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
7332 to util.c for parsing an HTTP header field value to extract the next
7333 list item, taking into account the possible presence of nested comments,
7334 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
7335 insignificant whitespace and lowercases non-quoted tokens.
7336 [Roy Fielding] PR#2065
7338 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
7339 code different from 500. This allows the proxy to, e.g., return
7340 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
7342 *) Fix ordering of language variants for the case where the traditional
7343 negotiation algorithm is being used with multiple language variants
7344 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
7346 *) Do not round the TCN quality calculation to 5 decimal places,
7347 unlike RFC 2296, because the calculation might need 12 decimal places
7348 to get the right result. [Roy Fielding]
7350 *) Remove unused code to disable transparent negotiation when
7351 negotiating on encoding only, as we now handle encoding too
7352 (though this is nonstandard for TCN), remove charset=ISO-8859-1
7353 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
7354 some debugging statements within mod_negotiation. [Koen Holtman]
7356 *) Fixed a rare memory corruption possibility in mod_dir if the index
7357 file is negotiable and no acceptable variant can be found.
7358 [Dean Gaudet, Roy Fielding, Martin Kraemer]
7360 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
7361 searching the Win32 registry for script interpreters.
7364 *) Win32: The compiled-in default filename for the error log is now
7365 error.log, which matches the default in the distributed httpd.conf.
7368 *) Win32: Any error messages from -i or -u command line options are now
7369 displayed on the console output rather than sent to the error log.
7370 Also the "Running Apache..." message is not output unless Apache is
7371 going to serve requests. [Paul Sutton]
7373 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
7374 and use a private significator ('$apr1$') to mark passwords as
7375 being smashed with our own algorithm. Also abstract the password
7376 checking into a new ap_validate_password() routine. [Ken Coar]
7378 *) Win32: The filename validity checker now allows "COM" but refuses
7379 access to "COM1" through "COM4". This allows filenames such
7380 as "com.name" to be served. [Paul Sutton] PR#3769.
7382 *) BS2000: Adapt to the new ufork() system call interface which will
7383 make subtasking easier on the OSD/POSIX mainframe environment.
7386 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
7387 ap_compat.h. [David White <david persimmon.com>] PR#3725
7389 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
7390 use `.db' instead of `.pag' not only for FreeBSD, but also when
7391 the NDBM library looks like Berkeley-DB based.
7392 [Ralf S. Engelschall] PR#3773
7394 *) Add ability to handle DES or MD5 authentication passwords.
7395 [Ryan Bloom <rbb Raleigh.IBM.Com>]
7397 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
7399 *) SECURITY: Avoid some buffer overflow problems when escaping
7400 quoted strings. (This overflow was on the heap and we believe
7401 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
7403 *) Let src/Configure be aware of CFLAGS options starting with plus
7404 signs as it's the case for the HP/UX compiler.
7405 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
7407 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
7408 and check to see if the tar we wind up with supports '-h'.
7409 [Jim Jagielski] PR#3671
7411 *) A consistent and conservative style for all shell scripts has been
7412 implemented. Basically, all shell string tests use the traditional
7413 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
7414 to protect against bare null variable strings (ie: wrapping both
7415 sides with double quotes and prepending 'x'). 'x' was chosen
7416 because it's more universal and hopefully easier for old shell
7417 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
7420 *) The status module now prints out both the main server generation as
7421 well as the generation of each process. Also, the vhost info is
7422 printed with '?notable'. [Jim Jagielski]
7424 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
7425 and this makes its functions available to things in src/support.
7428 Changes with Apache 1.3.4
7430 *) Renamed macros status_drops_connection to ap_status_drops_connection
7431 and vestigial scan_script_header to ap_scan_script_header_err,
7432 mostly for aesthetic reasons. [Roy Fielding]
7434 *) The query switch "httpd -S" didn't exit after showing the
7435 vhost settings. That was inconsistent with the other query functions.
7438 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
7439 filename to the end of the STANDARD_MODULE_STUFF. Its
7440 presence at the beginning prevented reporting of the filename
7441 for modules compiled before 1 January 1999. [Ken Coar]
7443 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
7444 to detect and prevent access to special DOS device file names.
7445 [Paul Sutton, Ken Parzygnat]
7447 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
7448 and Makefile_win32_debug.txt (debug build) that work on Win95.
7449 Run each of the following from the src directory:
7450 nmake /f Makefile_win32.txt # compiles normal build
7451 nmake /f Makefile_win32.txt install # compiles and installs
7452 nmake /f Makefile_win32.txt clean # removes compiled junk
7453 nmake /f Makefile_win32_debug.txt # compiles debug build
7454 nmake /f Makefile_win32_debug.txt install
7455 nmake /f Makefile_win32_debug.txt clean
7458 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
7459 to build binary distributions. [Lars Eilebrecht]
7461 *) IndexOptions SuppressColumnSorting only turned off making
7462 the column headers anchors; you could still change the display
7463 order by manually adding a '?N=A' or similar query string to the
7464 URL. Now SuppressColumnSorting locks in the sort order so
7465 it can't be overridden this way. [Ken Coar]
7467 *) Added IndexOrderDefault directive to supply a default sort order
7468 for FancyIndexed directory listings. [Ken Coar] PR#1699
7470 *) Change the ap_assert macro to a variant that works on all platforms.
7471 [Richard Prinz <richard.prinz cso.net>] PR#2575
7473 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
7474 search for an underscore on dlsym() (as it's already the case
7475 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
7477 *) Small fix for mod_env.html: The module was documented as to be _not_
7478 compiled into Apache per default, although it _IS_ compiled into
7479 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
7481 *) Instead of fixing a bug in the generation procedure for config.status (a
7482 backslash was missing) we remove the bug together with it's complete
7483 context because the special cases of the past can now no longer occur
7484 because of the recent magic for the --with-layout default.
7485 [Ralf S. Engelschall] PR#3590
7487 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
7488 making sure the src/support/ tools are _forced_ to be build last (they
7489 depend on other libraries).
7490 [Markus Theissinger <markus.theissinger gmx.de>]
7492 *) Fix installation procedure: Now that os-inline.c is actually used (a
7493 recently fixed bug prevented this) we need to also install os-include.c
7494 in addition to os.h into the PREFIX/include/ location or building of
7495 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
7497 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
7498 allow us to distinguish between a garbled DSO (or even a file which isn't
7499 an Apache module DSO at all) and a DSO which doesn't match the current
7500 Apache API. [Ralf S. Engelschall] PR#3152
7502 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
7503 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
7504 match case insensitive (this especially avoids nasty patterns like
7505 `[tT][eE][sS][tT]'). Second two additional internal map functions
7506 `escape' and `unescape' were added which can be used to escape/unescape
7507 to/from hex-encodings in URLs parts (this is especially useful in
7508 combination with map lookups).
7509 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
7511 *) Renamed the macro escape_uri() to ap_escape_uri() which was
7512 forgotten (because it was a macro) in the symbol renaming process.
7513 [Ralf S. Engelschall]
7515 *) Fix some inconsistencies related to the scopes of directives. The only
7516 user visible change is that the directives `UseCanonicalName' and
7517 `ContentDigest' now use the (more correct) `Options' scope instead of
7518 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
7520 *) Using DSO, the Server token was being mangled. Specifically, the
7521 module's token was being added first before the Apache token. This
7522 has been fixed. [Jim Jagielski]
7524 *) Major overhaul of mod_negotiation.c, part 2.
7525 - properly handle "identity" within Accept-Encoding.
7526 - allow encoded variants in RVSA negotiation and let them appear in
7527 the Alternates field using the non-standard "encoding" tag-list.
7528 - fixed both negotiation algorithms so that an explicitly accepted
7529 encoding is preferred over no encoding if "identity" is not
7530 included within Accept-Encoding.
7531 - added ap_array_pstrcat() to alloc.c for efficient concatenation
7532 of large substring sequences.
7533 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
7536 *) Major overhaul of mod_negotiation.c, part 1.
7537 - cleanups to mod_negotiation comments and code structure
7538 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
7539 support for everything in the upcoming HTTP/1.1
7540 revision (draft-ietf-http-v11-spec-rev-06.txt).
7541 - language tag matching also handles tags with more than 2
7543 - empty Accept, Accept-Language, Accept-Charset headers are
7544 processed correctly; previously an empty header would make all
7545 values acceptable instead of unacceptable.
7546 - allowed for q values in Accept-Encoding
7547 - added support for transparent content negotiation (rfc2295 and
7548 rfc2296) (though we do not implement all features in these drafts,
7549 e.g. no feature negotiation). Removed old experimental version.
7550 - implemented 'structured entity tags' for better cache correctness
7551 (structured entity tags ensure that caches which can deal with Vary
7552 will (eventually) be updated if the set of variants on the server
7554 - this involved adding a vlist_validator element to request_rec
7555 - this involved adding the ap_make_etag() function to the global API
7556 - modified guessing of charsets used by Apache negotiation algorithm
7557 to guess 'no charset' if the variant is not a text/* type
7558 - added code to sort multiviews variants into a canonical order so that
7559 negotiation results are consistent across backup/restores and mirrors
7560 - removed possibility of a type map file resolving to another type map
7561 file as its best variant
7562 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
7564 *) RFC2396 allows the syntax http://host:/path (with no port number)
7565 but the proxy disallowed it (ap_proxy_canon_netloc()).
7566 [David Kristol <dmk bell-labs.com>] PR#3530
7568 *) When modules update/modify the file name in the configfile_t structure,
7569 syntax errors will report the updated name, not the original one.
7570 [Fabien Coelho <coelho cri.ensmp.fr>] PR#3573
7572 *) Correct some filename case assumptions from WIN32 to
7573 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
7575 *) For %v log ServerName regardless of the UseCanonicalName
7576 setting (similarly for %p). [Dean Gaudet]
7578 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
7579 rather late (too late for some invocations of TestCompile).
7580 This improves the make environment available to TestCompile and
7581 the *.module scripts. [Martin Kraemer]
7583 *) The hashbang emulation code in ap_execve.c would interpret
7584 #!/hashbang/scripts correctly, but failed to fall back to a
7585 standard shell for scripts which did NOT start with #!
7586 Now SHELL_PATH is started in these cases. [Martin Kraemer]
7588 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
7591 *) Update APXS manual page: some -q option arguments were missing
7592 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
7594 *) Cleanup the command line options: `-?' was documented to show
7595 the usage list but does it with an error because `?' is not a valid
7596 command. OTOH a lot of users expect `-h' to print such a usage list and
7597 instead are annoyed for ages by our huge unreadable list of directives.
7598 So we now changed the command line options this way:
7600 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
7601 very similar to the popular linker option.
7603 Intent: while -l gives the small list of modules, -L now gives the
7604 large list of directives implemented by these modules. This is also
7605 consistent with -v (short version info) and -V (large version info).
7607 Intent: it's now the expected option ;-)
7608 The manual page was adjusted accordingly.
7609 [Ralf S. Engelschall] PR#2714
7611 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
7612 wasn't defined. [Rick Franchuk <rickf transpect.net>]
7614 *) Removed recently introduced bugs and disfigurements in APACI:
7615 o fixed argument line processing: using $args was broken: It was not
7616 initialized and using args="$args $apc_option" and even args="$args
7617 \"$apc_option\"" fails in the second processing round for any arguments
7618 containing whitespaces. The only correct way is to use the construct
7619 "$@" (but not possible here) or iterate _both_ times over the implicit
7620 argument line (no argument to for-loop) which is what we now use.
7621 o make --with-layout=Apache the default without creating
7622 redundancy (copying the --with-layout block in the argument parsing
7623 loop). We achieve this by using the "$@" construct together with the
7624 `set' command to prepend --with-layout=Apache to the command line in
7625 case --with-layout is not used.
7626 o fixed auto-suffix handling now that config.layout exists.
7627 Paths which are auto-suffixed are marked with a trailing plus sign in
7628 config.layout and every path now can be marked this way (not only the
7629 four paths for which we do it currently). Additionally the suffix is
7630 no longer a static one. Instead it's now `/<target>' where <target> is
7631 the argument of the --target option or per default `httpd'.
7632 o allow also tabs (and only spaces) where we match whitespaces
7633 o various fixes and cleanups related to used shell coding style
7634 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7635 o trimmed output of --help to fit into 80 columns
7636 [Ralf S. Engelschall]
7638 *) Added two new core API functions, ap_single_module_configure() and
7639 ap_single_module_init(), which are now used by mod_so to configure a module
7640 after loading. [Ralf S. Engelschall]
7642 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
7643 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
7644 of ap_config.h to allow serialized accept for multiport listens.
7645 [Roy Fielding, Curt Sampson] PR#3120
7647 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
7648 of ap_config.h that would skip several defines if DEFAULT_GROUP
7649 was overridden. [Roy Fielding]
7651 *) PORT: The I86 version of DGUX has support for strncasecmp and
7652 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
7654 *) Fix ordering of definitions in ap_config.h so that ap_inline is
7655 defined before it might be used. [Victor Khimenko]
7657 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
7658 [Tom Serkowski <tks bsdi.com>] PR#3453
7660 *) Make generation of src/Configuration.apaci more robust: It failed to
7661 differenciate between modules when one module name was a postfix of
7662 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
7663 just XXX (think about totally non-standard names like "apache_ssl", too).
7664 [Ralf S. Engelschall] PR#3380
7666 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
7667 since 1.3b7) and make whitespace handling more robust (it failed horrible
7668 when whitespaces were present in the arguments of -D options).
7669 [Ralf S. Engelschall] PR#3240
7671 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
7672 creates an external package shadow tree in DIR before the local build
7673 shadow tree is generated under DIR. This way one can have the extracted
7674 Apache distribution tree read-only on NFS or CDROM and still build Apache
7675 from these sources. An automatically triggered VPATH-like mechanism is
7676 provided through the TOP variable, too.
7677 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez apple.com>]
7679 *) Fix negotiation so that a Vary response header is correctly
7680 generated when, for a particular dimension, variants only vary
7681 in having or not having a value for that dimension. [Paul Sutton]
7683 *) Fix negotiation so that we prefer an encoded variant over an
7684 unencoded variant if the user-agent explicitly says it can
7685 accept that encoding. Previously we always preferred the unencoded
7687 [Paul Ausbeck <paula alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
7689 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
7690 and the usage page was inconsistent with the functionality and manpage.
7691 [Ralf S. Engelschall]
7693 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
7694 They can occur multiple times and their arguments (`xxx') are passed AS
7695 IS to the compiler/linker command. [Ralf S. Engelschall]
7697 *) Fixed possible (but harmless in practice) bug in the DBM lookup
7698 procedure of mod_rewrite: very long keys were truncated.
7699 [Ralf S. Engelschall]
7701 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
7702 identifier, currently "Apache" and "GNU" are pre-defined in the file
7703 config.layout. Custom layouts are possible by using FILE:ID as the
7704 argument where the layout ID is taken from FILE.
7706 The config.layout file consists of <Layout ID>..</Layout> sections
7707 where inside those sections "path_variable: path_value" pairs can be
7708 specified. These lines are converted to path_variable='path_value'.
7710 *) Add a DefaultLanguage directive so that files missing a language
7711 extension (e.g., .fr, .de) can be labelled as being some other
7712 default language. DefaultLanguage can appear in <Directory> and
7713 <Files> containers as well as .htaccess files. [Paul Sutton]
7716 *) Fix TARGET configuration when configuring and installing using
7717 APACI configure. TARGET now defines the basename of the configuration
7718 file, startup script, manual page, etc. log_error_core() now reports
7719 the server binary name given by argv[0]. TARGET can now also be defined
7720 with --target=TARGET parameter passed to APACI configure.
7721 [Ralf Engelschall, Randy Terbush]
7723 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
7724 rather than OPT_INCLUDES [Rainer Schoepf <schoepf uni-mainz.de>]
7726 *) ap_md5_binary() was using sprintf() rather than a table lookup
7727 to convert binary bytes to hex digits.

7744 and a redirect at the same time. [Lars Eilebrecht]
7746 *) Fallback to native compilers for IRIX-32 platform. It seems that
7747 a gcc 2.8.1 compiled apache is logging client addresses with all
7748 bits set (255.255.255.255). This is the second such problem caused
7749 by gcc 2.8.1 compiler. The first being broken semaphore locking.

7792 *) PORT: Add a port to the Concurrent PowerMAX OS. [Tom Horsley
7793 <Tom.Horsley mail.ccur.com>]
7795 *) WIN32: Log more explicit error messages if spawning an interpreted
7796 script failed, including the command line used to attempt to execute
7797 the interpreter and the Win32 error code returned. [Marc Slemko]
7799 *) Disable sending of error-notes on a 500 (Internal Server Error) response
7800 since it often includes file path info. Enable sending of error-notes
7801 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
7803 *) http_config.c would respond with 501 (Method Not Implemented) if a
7804 content type handler was specified but could not be found, which
7805 should have been a 500 response. Likewise, mod_proxy.c would responsd
7806 with a 501 if the URI scheme is unrecognized instead of the correct
7807 response of 403 (Forbidden). [Roy Fielding]
7809 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
7810 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
7812 *) Fix in mod_autoindex: for files where the last modified time stamp was
7813 unavailable, an empty string was printed which was 2 bytes short.
7814 The size and description columns were therefore not aligned correctly.
7815 [Martin Kraemer] (no PR#)
7817 *) Update BS2000 OS code to work with recent versions. Starting with
7818 release A17, the child fork() must be replaced by a _rfork().
7819 (BS2000 only) [Martin Kraemer]
7821 *) Add the actual server_rec structure of the specific Vhost to the
7822 scoreboard file and avoid a string copy (as well as allow some
7823 further future enhancements). [Harrie Hazewinkel
7824 <harrie.hazewinkel jrc.it>]
7826 *) Add APACI --permute-module=foo:bar option which can be used to
7827 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
7828 in the Configuration[.apaci] file. Two special and important variants are
7829 supported for the option argument: first BEGIN:foo which permutes module
7830 mod_foo with the begin of the module list, i.e. it `moves' the module to
7831 the begin of the list (gives it lowest priority). And second foo:END
7832 which permutes mod_foo with the end of the module list, i.e. it `moves'
7833 the module to the end of the list (gives it highest priority).

7836 *) Fix problem with 'apache -k shutdown' and startup event
7837 synchronisation (Win32). [Ken Parzygnat <kparz raleigh.ibm.com>]
7840 *) The config parser wasn't correctly noticing a missing '>'
7841 on container start lines (e.g., it wouldn't spot
7842 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom us.ibm.com>]
7845 *) Add a 'RemoveHandler' directive which will selectively remove
7846 all handler associations for the specified file extensions.
7847 [Ryan Bloom <rbbloom us.ibm.com>] PR#1799.
7849 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
7850 ResourceConfig directives on Win32. Also add a note to the effect
7851 of 'useless User directive ignored on Win32' to the errorlog if
7852 a User directive is encountered on Win32.

7855 *) Fix multiple whitespace handling in imagemaps for mod_imap which was
7856 broken since Apache 1.3.1 where we took out compressing of multiple
7857 spaces in ap_cfg_getline().
7858 [Ivan Richwalski <ivan seppuku.net>] PR#3249
7860 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
7861 initialized correctly and the db_open() call used an invalid mode
7862 parameter. [Ron Klatchko <ron ckm.ucsf.edu>] PR#3171
7864 *) PORT: DSO support for UnixWare 7
7865 [Ralf S. Engelschall, Ron Record <rr sco.com>]
7867 *) Merge the contents of the {srm,access}.conf-dist* files into the
7868 httpd.conf-dist* files. The srm and access files now contain
7869 only comments, and httpd.conf has all the combined contents in
7870 a rational order. [Ken Coar]
7872 *) PORT: DSO/ELF support for FreeBSD 3.0.
7873 [Ralf S. Engelschall, Dirk Froemberg <ibex physik.TU-Berlin.DE>]
7875 *) Add a "default-handler" handler that calls the default_hander()
7876 function which is normally called for static content. This allows
7877 you to override a specific handler. [Marc Slemko]
7879 *) Further simplify checking for absolute paths by replacing an
7880 hard-coded syntax check with a call to a routine we already created to
7881 do this. [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2976, 3074
7883 *) Log an error if we encounter a malformed "require" directive
7884 in mod_auth if we know that we know that no other module can
7885 deal with it. [Marc Slemko]
7887 *) Remove ap_private_extern method of hiding conflicting symbols
7888 on the NEXT platform because it is not correct for all versions,
7889 and the versions for which it is correct are unknown.
7890 [Wilfredo Sanchez <wsanchez apple.com>]
7892 *) Fix inheritance of IndexOptions NameWidth and remove unintended
7893 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]

7896 is encountered in an .htaccess file somewhere down the tree.
7899 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
7901 *) Fixed a segmentation violation in mod_proxy when a response is
7902 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
7904 Changes with Apache 1.3.3
7906 *) Added a complete implementation of the Expect header field as
7907 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
7908 response when we already know the final status, which is mighty
7909 useful for PUT responses that result in 302 or 401. [Roy Fielding]
7911 *) Remove extra trailing whitespace from the getline results as part
7912 of the protocol processing, which is extra nice because it works
7913 between continuation lines, is almost no cost in the normal case
7914 of no extra whitespace, and saves memory. [Roy Fielding]
7916 *) Added new HTTP status codes and default response bodies from the
7917 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
7918 HTTP Extension Framework (510) specifications. Did not add the
7919 WebDAV 424 and 425 codes because they are bogus. We don't use any
7920 of these codes yet, but they are now available to 3rd-party modules.
7923 *) Fix a possible race condition between timed-out requests and the
7924 ap_bhalfduplex select that might result in an infinite loop on
7925 platforms that do not validate the descriptor. [Roy Fielding]
7927 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
7928 running Apache server [Paul Sutton]

7931 of "-". [Martin Plechsmid <plechsmi karlin.mff.cuni.cz>, Marc Slemko]
7934 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker jetair.be>]

7941 [M. Laak <maert proinv.ee>] PR#3108

7948 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
7949 mod_auth_db by using ap_getword_white() (which uses ap_isspace())

7996 that missing files are not confused with unreadable files.
7999 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
8000 errno on an error, which leads to one error being mistaken for
8001 another when reading non-existent .htaccess files.
8004 *) OS/2: The new header tests get things right, need to update

8024 *) Fix bug in ap_remove_module(), which caused problems for dso's
8025 who were the top_module. [Doug MacEachern]
8027 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
8028 mod_auth_db to both be friendly to users who wants to use this version
8029 and to avoid problems under platforms where only version 2.x is present.
8030 [Dan Jacobowitz <drow false.org>, Ralf S. Engelschall]
8032 *) When using ap_log_rerror(), make the error message available to the
8033 *ERROR_NOTES envariables by default. [Ken Coar]
8035 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
8036 You now must define a BS2000Account name for the server User.
8037 This has fewer security implications than the old approach.
8040 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
8041 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
8042 platform to make the braindead HPUX linker happy. Notice, for the module
8043 DSOs we don't have to use this, because these are loaded manually (and
8044 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
8046 *) Remove 64 thread limit on Win32.
8047 [Bill Stoddard <stoddard raleigh.ibm.com>]
8049 *) Remove redundant substitutions in top-level Makefile.tmpl.

8053 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
8055 *) Make PrintPath work generically instead of having one version
8056 strictly for OS/2. [Jim Jagielski, Brian Havard]
8058 *) Fix the recently introduced C header file checking: We now use the C
8059 pre-processor pass only (and no longer the complete compiler pass) to
8060 determine whether a C header file exists or not. Because only this way
8061 we're safe against inter-header dependencies (which caused horrible
8062 portability problems). The only drawback is that we now have a CPP
8063 configuration variable which has to be determined first (we do a similar
8064 approach as GNU Autoconf does here). When all fails the user still has
8065 the possibility to override it manually via APACI or src/Configuration.
8066 As a fallback for the header check itself we can directly check the
8067 existance of the file under /usr/include, too.
8068 [Ralf S. Engelschall] PR#2777

8095 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
8096 trailing slash problem. [Jon Drukman <jsd gamespot.com>] PR#2933
8098 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
8099 platform, because it's only supported under version 4.0 and higher. But
8100 because our GuessOS is still unaware of Digital UNIX versions and the
8101 -msym is just to optimize the DSO statup time a little bit it's safe and
8102 best when we leave it out now. [Ralf S. Engelschall] PR#2969
8104 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
8105 functions: First all three functions no longer fail on strings containing
8106 "%" chars and second ap_log_printf() no longer does a double-formatting
8107 (instead it directly passes through the message to be formatted to the
8108 real internal formatting function). [Ralf S. Engelschall] PR#2941
8110 *) Allow "Include" directives anywhere in the server config
8111 files (but not .htaccess files). [Ken Coar] PR#2727
8113 *) The proxy was refusing to serve CONNECT requests except to
8114 port 443 (https://) and 563 (snews://). The new AllowCONNECT
8115 directive allows the configuration of the ports to which a
8116 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
8118 *) mod_expires will now act on content that is not sent from a file
8119 on disk. Previously it would never add an Expires: header to
8120 any response that did not come from a file on disk; the only
8121 case where it still doesn't (and can't) add one for that type of
8122 content is if you are using a modification date based setting.
8123 [Marc Slemko, Paul Phillips <paulp go2net.com>]
8125 *) Problems encountered during .htaccess parsing or CGI execution
8126 that lead to a "500 Server Error" condition now provide explanatory
8127 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
8130 *) Add NameWidth keyword to IndexOptions directive so that the
8131 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
8134 *) Recognize lowercase _and_ uppercase `uname' results under
8135 SCO OpenServer. [David Coelho <drc ppt.com>]
8137 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
8138 a common problem of (mis-administrated?) IIS servers, make the apache
8139 proxy immune to these errors (and ignore the duplicates, but log
8140 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
8142 *) The <IfModule and <IfDefine block starting directives now only
8143 allow exactly one argument. Previously, the optional negation
8144 character '!' could be separated by whitespace without a syntax
8145 error being reported, albeit defeating the IfModule functionality
8146 (enclosed directives would ALWAYS be executed). By using the
8147 stricter syntax, these hard-to-track errors can be avoided.
8150 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
8151 cause the standalone FancyIndexing directive to logically OR
8152 into any existing IndexOptions settings rather than wiping
8153 them out. [Ken Coar]
8155 *) Changes in ftp proxy: make URL parsing simpler by using the
8157 + Add display of the "current directory" in cases where it's
8158 different from the supplied path (e.g., ftp://user@host/ lives
8159 in /home/user, not in /, therefore clicking on "../" in the
8160 starting directory might send us to /home/).
8161 + When ftp login fails, (esp. when a user name was part of the
8162 URL already), we now return [401 Unauthorized ] to allow the
8163 browser to pop up an authorization dialog. This makes passwords
8164 slightly less visible (they don't appear in the regular log files)
8165 and implements a functionality that other www proxy servers
8169 *) Triggered by the recent "Via:" header changes, the proxy module would
8170 dump core for replies with invalid headers (e.g., duplicate
8171 "HTTP/1.0 200 OK" lines). These errors are now logged and the
8172 core dump is avoided. Also, broken replies are not cached.
8173 [Martin Kraemer] PR#2914
8175 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
8176 plop gmon.out profile data for each child [Doug MacEachern]

8179 config.status script to be immune against arguments with whitespaces.
8180 [Yves Arrouye <yves apple.com>] PR#2866
8182 *) Replace the inlined information grabbing stuff for the configuration
8183 adjustment feature (no --without-confadjust) with calls to a new helper
8184 script `buildinfo.sh' which is both more flexible and already proofed to
8185 be more robust against platform differences. This mainly fixes the
8186 recently occured ``sed: command garbled: ...'' problems.

8207 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
8208 5 to 10 because there are some users out there who always have 5 to 8
8209 variables in one RewriteRule and had to patch mod_rewrite.h for every
8210 release. So 15 should be now more than enough, even for them. (I never
8211 needed more than 4 in my RewriteRules ;-)
8212 [Ralf S. Engelschall]
8214 *) Make the proxy generate and understand Via: headers
8217 *) Change the proxy to use tables instead of array_headers for
8218 the header lines. [Martin Kraemer]
8220 *) Make sure the config.status file is not overridden when just
8221 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
8223 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
8224 provide a way to trace API changes that add functionality but do
8225 not create a compatibility issue for precompiled modules, etc.
8226 See include/ap_mmn.h for more details. [Randy Terbush]
8228 *) Fix suexec installation under `make install root=xxx' situation.
8229 [Ralf S. Engelschall]
8231 *) Extend the output of the -V switch to include the paths of all
8232 compiled-in configuration files, if they were overridden at
8233 compile time, for least astonishment of the user.
8236 *) When READing a request in ExtendedStatus mode, the "old"
8237 vhost, request and client information is not displayed.
8240 *) STATUS is no longer available. Full status information now
8241 run-time configurable using the ExtendedStatus directive.
8244 *) SECURITY [CAN-1999-1199] (cve.mitre.org):
8245 Eliminate O(n^2) space DoS attacks (and other O(n^2)
8246 cpu time attacks) in header parsing. Add ap_overlap_tables(),
8247 a function which can be used to perform bulk update operations
8248 on tables in a more efficient manner.
8251 *) SECURITY: Added compile-time and configurable limits for
8252 various aspects of reading a client request to avoid some simple
8253 denial of service attacks, including limits on maximum request-line
8254 size (LimitRequestLine), number of header fields (LimitRequestFields),
8255 and size of any one header field (LimitRequestFieldsize). Also added
8256 a configurable directive LimitRequestBody for limiting the size of the
8257 request message body. [Roy Fielding]

8273 ap_scan_script_header_err_core() [Doug MacEachern]
8275 *) The 'status' module will now show the process pid's and their
8276 state even without full STATUS accounting. [Jim Jagielski]
8278 *) Restore the client IP address to the error log messages, this
8279 was lost during the transition from 1.2 to 1.3. Add a new
8280 function ap_log_rerror() which takes a request_rec * and
8281 formats it appropriately. [Dean Gaudet] PR#2661
8283 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
8284 whitespace in input lines -- including within quoted strings.
8286 but leading and trailing whitespace should continue to be
8287 stripped [Martin Kraemer]
8289 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
8290 the ugly use of an env. variable and use command-line args for
8291 alternate $PATH. Make more like advanced 'type's as well.

8309 disabled for all platforms to avoid problems with this (experimental)

8623 than strcmp() to check for parent directory-ness of an entry. Oh, and
8624 make sure the parent directory (if displayed) is *always* listed first
8625 regardless of the sort key. Overall performance winnage should be good
8626 in CPU time, instruction cache, and memory usage, particularly for large

8636 *) Add httpd -t (test) option for running configuration syntax tests only.
8637 If something is broken it complains and exits with a return code
8638 non-equal to 0. This can be used manually by the user to check the Apache
8639 configuration after editing and is also automatically used by apachectl
8640 on (graceful) restart command to make sure Apache doesn't die on restarts
8641 because of a configuration which is now broken since the last (re)start.
8642 This way `apachectl restart' can be used inside cronjobs without having

8788 programs: ap_spawn_child_err() is used and the Win32 case now uses
8789 CreateProcess() instead of a low-level execl() (which caused problems in
8790 the past under Win32).
8791 [Ralf S. Engelschall]
8793 *) A few cosmetics and trivial enhancements to APXS to make the
8794 generated Makefile more user friendly. [Ralf S. Engelschall]
8796 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
8797 was updated to use the normal apache error processing, thereby allowing
8798 proxy errors to be treated by ErrorDocument's as well. For this
8799 purpose, a new module-to-core communication variable "error-notes"
8800 was introduced; the proxy (and possibly other modules) communicates
8801 its error text using this variable. Its content is copied to a new
8802 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
8803 The old proxy special error routine ap_proxy_log_uerror()
8804 was replaced by regular ap_log_error() calls, many messages were made
8806 [Martin Kraemer] PR#494, 1259
8808 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
8811 *) Transform the configure message "You need root privileges for suEXEC"
8812 from a fatal error into a (more friendly) warning because the building
8813 ("make") of Apache we can allow, of course. Root privileges are needed
8814 only for the installation step ("make install"). So make sure the
8815 user is aware of this fact but let him proceed as long as he can.
8816 [Ralf S. Engelschall] PR#2288
8818 *) Renamed three more functions to common ap_ prefix which we missed at the
8819 Big Symbol Renaming because they're #defines and not real C functions:
8820 is_default_port(), default_port(), http_method().
8821 [Ralf S. Engelschall]
8823 *) A zero-length name after a $ in an SSI document should cause
8824 just the $ to be in the expansion. This was broken during the
8825 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
8827 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
8828 memory. [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2252
8830 *) Fix src/support/httpd.exp (DSO export file which is currently only
8831 used under AIX) because of recent changes to function names.
8832 [Ralf S. Engelschall]
8834 Changes with Apache 1.3b7
8836 *) Make sure a MIME-type can be forced via a RewriteRule even when no
8837 substitution takes place, for instance via the following rule:
8838 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
8839 requested by users in the past to force a single script without a .cgi
8840 extension and outside any cgi-bin dirs to be executed as a CGI program.
8841 [Ralf S. Engelschall] PR#2254
8843 *) A fix for protocol issues surrounding 400, 408, and
8844 414 responses. [Ed Korthof]
8846 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
8848 *) Fix discrepancy in proxy_ftp.c which was causing failures when
8849 trying to connect to certain ftpd's, such as anonftpd.
8850 [Rick Ohnemus <rick ecompcon.com>]
8852 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
8853 logfile instead of fiddling around itself with child spawning stuff.
8854 [Ralf S. Engelschall]
8856 *) Made RefererIgnore case-insensitive.
8858 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
8861 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
8862 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
8865 *) Improve RFC1413 support. [Bob Beck <beck bofh.ucs.ualberta.ca>]
8867 *) Fix support script `dbmmanage': It was unable to handle some sort
8868 of passwords, especially passwords with "0" chars.
8869 [Ralf S. Engelschall] PR#2242
8871 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
8872 [Ben Laurie] PR#2238
8874 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
8875 library), so CGI handling has been changed to use Win32 native handles
8876 instead of C file descriptors.
8877 [Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
8879 *) The proxy cache would store an incorrect content-length in the cached
8880 file copy after a cache update. That resulted in repeated fetching
8881 of the original copy instead of using the cached copy.
8882 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
8884 *) The Makefiles assumed that DSO files are build via $(LD). This
8885 is broken for two reasons: First we never defined at least LD=ld
8886 somewhere to make sure this works (it was silently assumed that most Make
8887 provide a built-in LD definition - ARGL!) and second using the generic LD
8888 variable is not the truth. Instead a special variable named LD_SHLIB is
8889 reasonable because although "ld" is usually the default, the command for
8890 building DSO files can be "libtool" or even "cc" on some systems.
8891 [Ralf S. Engelschall]
8893 *) Replace the AddVersionPlatform directive with ServerTokens which
8894 provides for more control over the format of the Server:
8895 header line. SERVER_SUBVERSION is no longer supported;
8896 all module should use the ap_add_version_component()
8897 API function instead. [Jim Jagielski]
8899 *) Support for the NCR MP/RAS 3.0
8900 [John Withers <withers semi.kcsc.mwr.irs.gov>]
8902 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
8903 not retrieved in src/Configure and thus was not useable.
8904 [Ralf S. Engelschall]
8906 *) Various Makefile consistency cleanups:
8907 - make OSDIR also automatically be relative to src/ like INCDIR
8908 - SUBDIRS is now generated in src/Makefile only and not in
8909 Makefile.config because it is a local define for this location.
8910 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
8911 any Makefile but make sure that at least the "-K inline" is kept in
8913 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
8914 - updated the dependencies theirself
8915 - removed not existing SHLIB variable from "clean" targets
8916 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
8917 already exists and OBJS_PIC are also just plain objects and have not
8918 directly to do with "shared" things. The only difference is that they
8919 contain PIC. So OBJS_PIC is the more canonical name.
8920 - Updated the Makefile-dependency lines for OBJS_PIC
8921 - Removed the Makefile-dependency line in Configure to avoid double
8923 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
8924 of xxx.lo as GNU libtool does with its PIC objects
8925 - reduce local complexity in modules Makefile.tmpl by moving the last
8926 existing target "depend" to the generation section in Configure, too.
8927 - removed the historical $(SPACER) which was used in the past together
8928 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
8929 is no longer needed.
8930 - force the build and run of the gen_xxx programs under main/ as the
8931 first step before building the objects because it looks cleaner
8932 [Ralf S. Engelschall]
8934 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
8937 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
8940 *) WIN32: Don't force ISAPI headers to finish with \n.
8941 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
8943 *) When opening "configuration" files (like httpd.conf, htaccess
8944 and htpasswd), Apache will not allow them to be non-/dev/null
8945 device files. This closes a DoS hole. At the same time,
8946 we use ap_pfopen to open these files to handle timeouts.
8947 [Jim Jagielski, Martin Kraemer]
8949 *) Apache will now log the reason its httpd children exit if they exit
8950 due to an unexpected signal. (It requires a new porting define,
8951 SYS_SIGLIST, which if defined should point to a list of text
8952 descriptions of the signals available. See PORTING.) [Dean Gaudet]
8954 *) WIN32: chdir() doesn't make sense in a multithreaded environment
8955 like WIN32. Before, Win32 CGI's could have had sporadic failures
8956 if a chdir call from one thread was made between another chdir call
8957 and a spawn in another thread. So, for now don't chdir for CGI scripts
8958 in WIN32. The current CGI "spec" is unclear as to whether it's
8959 necessary. Long-term fix is to either serialize the chdir/spawn combo
8960 or use WIN32 native calls to spawn a process. This temp fix was
8961 necessary to remove this as a showstopper for 1.3's release.
8964 *) Cleanup the suEXEC support in APACI and make it more safe:
8965 1. Add big fat hint in INSTALL about risks and to read the
8966 htdocs/manual/suexec.html document before using the suexec-related
8968 2. Make sure the user has at least provided one --suexec-xxxx option
8969 (specifies suEXEC parameters) in addition to --enable-suexec option.
8970 If only --enable-suexec is given APACI stops with a hint to INSTALL
8971 and htdocs/manual/suexec.html documents.
8972 3. Provide two additional --suexec-xxxx options to make the suEXEC
8973 configuration complete (especially for package maintainers who else
8974 had to patch the source tree) by providing ways to configure minimal
8975 UID/GID and safe PATH, too.
8976 [Ralf S. Engelschall]
8978 *) Cleanup of the `configure --shadow' process:
8979 - make sure the configure script creates its temporary files in the
8980 shadow tree to avoid conflicts with parallel configure runs
8981 - removed unnecessary option "-r" from "rm" call for Makefiles
8982 - make sure the configure scripts creates the shadow-wrapper Makefile
8983 only when no shadow trees already exists
8984 - make sure "make distclean" removes the shadow-wrapper Makefile but only
8985 when no more shadow trees exists
8986 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
8987 as fast (in the past it needed 70sec, now it runs just 38sec)
8988 - make sure CVS does not complain about the created files
8989 Makefille.<gnutriple> and directories src.<gnutriple>
8990 [Ralf S. Engelschall]
8992 *) Added the ap_add_version_component() API routine and the
8993 AddVersionPlatform core directive. The first allows modules to
8994 declare themselves in the Server response header field value,
8995 augmenting the SERVER_SUBVERSION define in the Configuration file
8996 with run-time settings (more useful in a loadable-module environment).
8997 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
8998 into the server version string. [Ken Coar] PR#2056
9000 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
9003 *) Emit the "Accept-Range" header for the default handler.
9004 [Brian Behlendorf] PR#1464
9006 *) Add a note to httpd.conf-dist that apache will on some systems fail
9007 to start when the Group # is set to a negative or large positive value.
9010 *) Make sure the module execution order is correct even when some modules
9011 are loaded under runtime (`LoadModule') via the DSO mechanism:
9012 1. The list of loaded modules is now a dynamically allocated one
9013 and not the original statically list from modules.c
9014 2. The loaded modules are now correctly setup by LoadModule for
9015 later use by the AddModule command.
9016 3. When the DSO mechanism for modules is used APACI's `install'
9017 target now enables all created `LoadModule' lines per default because
9018 this is both already expected by the user _and_ needed to avoid
9019 confusion with the next point and reduces the Makefile.tmpl complexity
9020 4. When the DSO mechanism for modules is used, APACI's `install'
9021 target now additionally makes sure the module list is reconstructed
9022 via a complete `ClearModuleList+AddModule...' entry.
9023 5. The support tool `apxs' now also makes sure an AddModule command
9024 is added in addition to the LoadModule command.
9025 6. The modules.c generation was extended to now contain two
9026 comments to make sure no one is confused by the confusing terminology
9027 of loading/linking (we use load=link+load & link=activate instead of
9028 the obvious load=activate & link=link :-( )
9029 This way now there is no longer a difference under execution time between
9030 statically and dynamically linked modules.
9031 [Ralf S. Engelschall]
9033 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
9034 Big Symbol Renaming. [Ralf S. Engelschall]
9036 *) Add a comment to mod_example.c showing the format of a FLAG command
9039 *) Standardized the time format in mod_status to match that of other
9040 places in the code (e.g. DATE_GMT). PR#1551
9042 *) Fix handling of %Z in timefmt strings for those platforms with no time
9043 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
9046 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
9047 feature compatible with 'UseCanonicalName off' by changing
9048 r->server->server_hostname to ap_get_server_name(). And I changed some
9049 functions which use r->server->port to use ap_get_server_port() instead,
9050 because if there's no Port directive in the config r->server->port is 0.
9053 *) get/set_module_config are trivial enough to be better off inline. Worth
9054 1.5% performance boost. [Dean Gaudet]
9056 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
9057 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
9060 *) [BS2000 security] BS2000 needs an extra authentication to initialize
9061 the task environment to the unprivileged User id. Otherwise CGI scripts
9062 would have a way to gain super user access. [Martin Kraemer]
9064 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
9065 absolute path, only log base name of logging source as is done
9066 in unix. [Martin Kraemer]
9068 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
9069 the encoding type from the Accept-Encoding header (if it's there)
9070 and use it in the response, as that's probably what it'll be expecting.
9071 [<Ronald.Tschalaer psi.ch>]
9073 *) Fix to mod_alias: translate_alias_redir is dealing with
9074 a URI, not a filename, so the check for drive letters for win32
9075 and emx is not necessary. [Dean Gaudet]
9077 *) WIN32: Allow .cmd as an executable extension.
9078 [Kari Likovuori <Kari.Likovuori mol.fi>] PR#2146
9080 *) Make Apache header files, and some variables, C++ friendly.
9081 [Michael Anderson's <mka redes.int.com.mx>]
9083 *) Child processes can now "signal" (by exiting with a status
9084 of APEXIT_CHILDFATAL) the parent process to abort and
9085 shutdown the server if the error in the child process was
9086 fatal enough. [Jim Jagielski]
9088 *) mod_autoindex's find_itme() was sensitive to MIME type case.
9089 [Jim Jagielski] PR#2112
9091 *) Make sure the referer_log and agent_log entries in the default httpd.conf
9092 file are also adjusted for the actual relative installation paths.
9093 [Ralf S. Engelschall] PR#2175
9095 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
9097 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
9100 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
9101 Additionally the checks for finding the vendor DSO library were moved
9102 from mod_so.c to Configure because first it needs $PLAT etc. and second
9103 mod_so already uses an abstraction layer and does not fiddle with the
9104 vendor functions itself.
9105 [Jens-Uwe Mager, Ralf S. Engelschall]
9107 *) PORT: Some optimization defines for NetBSD
9108 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
9110 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
9111 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
9113 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
9114 AIX variants should work fine, too. Even AIX 3.x should work). This is
9115 accomplished by using the free DSO emulation code from Jens-Uwe Mager
9116 which we put into a os/unix/os-dso-aix.c file.
9117 [Ralf S. Engelschall]
9119 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
9120 that we should use NET_SIZE_T == int but the include files force size_t.
9121 [Ralf S. Engelschall]
9123 *) Fix two bugs in select() handling in http_main.c.
9126 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
9127 is unset (as it is in situations like timeouts) where it is unclear
9128 whether errno is set or not. [Martin Kraemer]
9130 *) Just having APACI's localstatedir is too general and not enough for most
9131 of the systems. 1.3b6 again required manual APACI patches by package
9132 maintainers from Red Hat and FreeBSD because for their filesystem layout a
9133 little bit more flexibility in configuring the paths is needed. Hence we
9134 provide three additional configure options (--runtimedir, --logfiledir,
9135 --proxycachedir) which now can be used for more granular adjustments if
9136 --localstatedir is not enough to fit the particular needs. As a nice
9137 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
9138 [Ralf S. Engelschall]
9140 *) Make the install root for "make install" in APACI's Makefile overrideable
9141 by package authors. This way we are even more friendly to package
9142 maintainers (especially Debian and Red Hat) who build for the real prefix
9143 via "configure --prefix=/<real>" but use a different local prefix via
9144 "make root=/tmp/apache install" for rolling the package without bristling
9145 the target location on their system.
9146 [Ralf S. Engelschall]
9148 *) Workaround sed limitations in APACI's configure script by now
9149 substituting in chunks of 50 commands (because for instance HPUX's vendor
9150 sed has a limit of max. 98 commands)
9151 [Ralf S. Engelschall] PR#2136
9153 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
9154 [Ralf S. Engelschall] PR#2140
9156 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
9157 RENAMING process because they are defined as pre-processor macros instead
9158 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
9159 [Ralf S. Engelschall]
9161 *) Workaround braindead AWK's when generating ap_config.h: The split() and
9162 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
9163 [Ralf S. Engelschall] PR#2139
9165 *) Various bugfixes and cleanups for the APACI configure script:
9166 o fix IFS handling for _nested_ situation
9167 o fix Perl interpreter search: take first one found instead of last one
9168 o fix DSO consistency check
9169 o print error messages to stderr instead of stdout
9170 o add install-quiet for --shadow situation to Makefile stub
9171 o reduce complexity by avoiding sed-hacks for rule and module list loops
9172 [Ralf S. Engelschall]
9174 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
9176 *) Make sure the input field separator (IFS) shell variable is explicitly
9177 initialized correctly before _every_ `for' loop and also restored after
9178 the loops. [Ralf S. Engelschall]
9180 *) Make sure that "make install" doesn't overwrite the `mime.types' and
9181 `magic' files from an existing Apache installation. Because people often
9182 customize these for own MIME and content types.
9183 [Ralf S. Engelschall]
9185 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
9186 [Peter Galbavy, Ralf S. Engelschall] PR#2109
9188 *) Fix the path to the ScoreBoardFile in the install-config target, too.
9189 [Ralf S. Engelschall] PR#2105
9191 *) Let "configure" clear out the users parameters (provided as shell
9192 variables) to avoid side-effects in "src/Configure" when the user
9193 exported them (which is not needed, but some users do it).
9194 [Ralf S. Engelschall] PR#2101
9196 *) Provide backward compatibility from some old src/Configuration.tmpl
9197 parameter names to the canonical Autoconf-style shell variable names. For
9198 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
9199 but a hint message is displayed. [Ralf S. Engelschall]
9201 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
9202 CGI scripts from an existing Apache installation.
9203 [Ralf S. Engelschall, Jim Jagielski] PR#2084
9205 *) Make `configure --compat' more "compatible" by first
9206 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
9207 second by making sure the "avoid-bristling-suffix" /apache is not
9208 appended to sysconfdir, datadir, localstatedir and includedir when
9209 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
9211 *) NeXT required strdup() in support/logresolve.c

9217 *) Fix the path to the MimeMagicFile in the install-config target, too.
9218 [Ralf S. Engelschall] PR#2089
9220 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
9222 *) If you start apache with the -S command line option it will dump
9223 out the parsed vhost settings. This is useful for folks trying
9224 to figure out what is wrong with their vhost configuration.
9225 (Other dumps may be added in the future.) [Dean Gaudet]
9227 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
9228 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
9231 *) Because /usr/local/apache is the default prefix the ``configure
9232 --compat'' option no longer has to set prefix, again. This way the
9233 --compat option honors a leading --prefix option. [Lars Eilebrecht]
9235 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
9236 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
9237 to avoid "discard const" warnings. [Ralf S. Engelschall]
9239 *) If a specific handler is set for a file yet the request still
9240 ends up being handled by the default handler, log an error
9241 message before handling it. This catches things such as trying
9242 to use SSIs without mod_include enabled. [Marc Slemko]
9244 *) Fix error logging for the startup case where ap_log_error() still uses
9245 stderr as the target. Now the default log level is honored here, too.
9246 [Ralf S. Engelschall]
9248 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
9249 long" errors when generating the MODULES entry for src/Makefile
9250 [Ben Hyde, Ralf S. Engelschall]
9252 *) Make sure src/Configure doesn't complain about the old directory
9253 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
9255 Changes with Apache 1.3b6
9257 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
9259 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
9260 interface via the similar but proprietary HP/UX shl_xxx-style system
9261 calls. [Ralf S. Engelschall]
9263 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
9264 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
9265 Make. [Ralf S. Engelschall]
9267 *) ++++ THE BIG SYMBOL RENAMING ++++
9268 To avoid symbol clashes with third-party code compiled into the server,
9269 we globally applied the prefix "ap_" to the following classes of
9271 - Apache provided general functions (e.g., ap_cpystrn)
9272 - Public API functions (e.g., palloc, bgets)
9273 - Private functions which we can't make static (because of
9274 cross-object usage) but should be (e.g., new_connection)
9275 For backward source compatibility a new header file named compat.h was
9276 created which provides defines for the old symbol names and can be used
9277 by third-party module authors.
9280 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
9281 problem under SVR4 is that there is no command flag to force the linker
9282 to export the global symbols of the httpd executable therewith they are
9283 available to the DSO's. Instead of problematic hacks like creating a
9284 dummy.so file (containing dummy references to all global symbols) the
9285 httpd binary is linked against, we use a clean trick stolen from Perl 5:
9286 Placing the Apache core code itself into a DSO library named libhttpd.so.
9287 This way the global symbols _HAVE_ to be exported and thus are available
9288 to any manually loaded DSO's under runtime. To reduce the impact to the
9289 user to null we go even further and create a stub httpd executable which
9290 automatically keeps track of the DSO library loading itself and thus
9291 hides the complete mechanism from the user. Although the generation of
9292 this DSO library is automatically triggered for platforms which
9293 essentially need it (mostly all SVR4-derivates) it can be also enabled
9294 manually via the Rule SHARED_CORE. This can be interesting in the future
9295 where we perhaps exploit this libhttpd.so mechanism for providing nifty
9296 features like graceful upgrades, or whatever.
9297 [Ralf S. Engelschall, Martin Kraemer]
9299 *) Build the libraries before building the rest of the tools. [Ben Hyde]
9301 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
9302 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
9303 conventions while "clean" removes only stuff created by "all" targets,
9304 "distclean" additionally removes the stuff from the configuration
9305 process. This way "make distclean" (hence the name) provides a fresh
9306 source tree as it was for distribution.
9307 [Ralf S. Engelschall]
9309 *) Allow top-level (APACI) Makefile to break on build errors
9310 the same way the src/ subtree Makefiles breaks on them by replacing the
9311 initial APACI sed-subdir-display-kludge with a more clean
9312 variable-passing-solution: variable SDP can optionally hold the subdir
9313 prefix which is consistently used for displaying the subdir movement.
9314 This way even the top-level Makefile can stop correctly on errors as the
9315 user expects. [Ralf S. Engelschall]
9317 *) Fixed ordering of argument checks for RewriteBase directive.
9318 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
9320 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
9321 indicating that a module is being compiled for dynamic loading. Also
9322 remove #define IS_MODULE from modules and add SHARED_MODULE define
9323 to the mak/dsp files. [Alexei Kosut]
9325 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
9326 since we are now logging APLOG_WARNING by default. [Roy Fielding]
9328 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
9330 *) Add documentation file and src/Configuration.tmpl entry for the
9331 experimental mod_mmap_static module. Because although it is and marked as
9332 an experimental one it is distributed and thus should be documented and
9333 prepared for configuration the same way as all others modules.
9334 [Ralf S. Engelschall]
9336 *) Add query (-q) option to apxs support tool to be able to manually query
9337 specific settings from apxs. This is needed for instance when you
9338 manually want to access Apache's header files and you need to assemble
9339 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
9340 [Ralf S. Engelschall]
9342 *) Now src/Configure uses a fallback strategy for the shared object support
9343 on platforms where no explicit information is available: If a Perl
9344 installation exists we ask it about its shared object support and if it's
9345 the dlopen-style one we shamelessly guess the compiler and linker flags
9346 for creating shared objects from Perls knowledge. Of course, the user is
9347 warning about what we are doing and informed that he should send us
9348 the guessed flags when they work. [Ralf S. Engelschall]
9350 *) Provide APACI --without-support option to be able to disable the build
9351 and installation of the support tools from the src/support/ area.
9352 Although its useful to have these installed per default we should provide
9353 a way to compile and install without them for backward-compatibility.
9354 [Ralf S. Engelschall]
9356 *) Add of the new APache eXtenSion (apxs) support tool for building and
9357 installing modules into an _already installed_ Apache package through the
9358 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
9359 this approach actually doesn't need the Apache source tree. The
9360 (APACI-installed) server package is enough, because this now includes the
9361 Apache C header files (PREFIX/include) and the new APXS tool
9362 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
9363 module authors to build their Apache modules _OUTSIDE_ the Apache source
9364 tree while avoiding them to fiddle around with the totally platform
9365 dependend way of compiling DSO files. The tool supports all ranges of
9366 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
9367 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
9368 on-the-fly generate a minimalistic Makefile and sample module for the
9369 first step to provide both a quick success event and to demonstrate the
9370 APXS mechanism to module authors. [Ralf S. Engelschall]
9372 *) Fix core dumps in use of CONNECT in proxy.
9373 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
9375 *) Modify the log directives in httpd.conf-dist files to use CustomLog
9376 so that users have examples of how CustomLog can be used.
9379 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
9380 the Apache distribution tree. Until Apache 1.3 there was no real
9381 out-of-the-box batch-capable build and installation procedure for the
9382 complete Apache package. This is now provided by a top-level "configure"
9383 script and a corresponding top-level "Makefile.tmpl" file. The goal is
9384 to provide a GNU Autoconf-style frontend which is capable to both drive
9385 the old src/Configure stuff in batch and additionally installs the
9386 package with a GNU-conforming directory layout. Any options from the old
9387 configuration scheme are available plus a lot of new options for flexibly
9388 customizing Apache. [Ralf S. Engelschall]
9390 *) The floating point ap_snprintf code wasn't threadsafe.
9391 Had to remove the HAVE_CVT macro in order to do threadsafe
9392 calling of the ?cvt() floating point routines. [Dean Gaudet]
9394 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
9396 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
9397 [Jim Jagielski] PR#1901
9399 *) BUG: Configure was using TCC and CC inconsistently. Make sure
9400 Configure knows which CC we are using. [Jim Jagielski]
9402 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
9403 was defined in a parent directory. [Lars Eilebrecht]
9405 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
9406 a generic printf-style routine that can call arbitrary output
9407 routines. Use this to replace http_bprintf.c. Add new routines
9408 psprintf(), pvsprintf() which allocate the exact amount of memory
9409 required for a string from a pool. Use psprintf() to clean up
9410 various bits of code which used ap_snprintf()/pstrdup().
9413 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
9414 ap_snprintf() has different semantics and formatting codes than
9415 snprintf(). [Dean Gaudet]
9417 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
9418 is necessary on at least Solaris where the /etc/rc?.d scripts
9419 are run with these signals ignored, and "SIG_IGN" settings are
9420 maintained across exec().
9421 [Rein Tollevik <reint sys.sol.no>] PR#2009
9423 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
9424 used instead of lstat() and thus this flag didn't work as expected.
9425 [Rein Tollevik <reint sys.sol.no>] PR#2010
9427 *) Fix the proxy pass-through feature of mod_rewrite for the case of
9428 existing QUERY_STRING now that mod_proxy was recently changed because of
9429 the new URL parsing stuff. [Ralf S. Engelschall]
9431 *) A few changes to scoreboard definitions which helps gcc generate
9432 better code. [Dean Gaudet]
9434 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
9435 be a signed bitfield. So mark a few bitfields as signed to
9436 ensure correct code. [Dean Gaudet]
9438 *) The default for HostnameLookups was changed to Off, but there
9439 was a problem and it wasn't taking effect. [Dean Gaudet]
9441 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
9444 *) After a SIGHUP the listening sockets in the parent weren't
9445 properly marked for closure on fork().
9446 [Jürgen Keil <jk tools.de>] PR#2000
9448 *) Allow %2F in two situations: 1) it is in the query part of the URI,
9449 therefore not exposed to %2F -> '/' translations and 2) the request
9450 is a proxy request, so we're not dealing with a local resource anyway.
9451 Without this, the proxy would fail to work for any URL's with
9452 %2f in them (occurs quite often in
9453 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
9455 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
9457 *) Make the shared object compilation command more portable by avoiding
9458 the direct combination of `-c' & `-o' which is not honored by some
9459 compilers like UnixWare's cc. [Ralf S. Engelschall]
9461 *) WIN32: the proxy was creating filenames missing the last four
9462 characters. While this normally doesn't stop anything from
9463 working, it can result in extra collisions.
9464 [Tim Costello <tjcostel socs.uts.edu.au>] PR#1890
9466 *) Now mod_proxy uses the response string (in addition to the response status
9467 code) from the already used FTP SIZE command to setup the Content-Length
9468 header if available. [Ralf S. Engelschall] PR#1183
9470 *) Reanimated the (still undocumented) proxy receive buffer size directive:
9471 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
9472 name was really too generic, added documentation for this directive to
9473 the mod_proxy.html and corrected the hyperlink to it in the
9474 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
9476 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
9477 faster [Martin Kraemer]
9479 *) Make Configure die when you give it an unknown command switch.
9482 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
9483 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
9484 and per default compiled support programs have manual pages - just to
9485 document our stuff a little bit more and to be able to do really
9486 Unix-like installations ;-) [Ralf S. Engelschall]
9488 *) Major cleanups to the Configure script to make it and its generated
9489 Makefiles again readable and maintainable: add SRCDIR option, removed
9490 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
9491 generated sections, consequently added Makefile headers with inheritance
9492 information, added subdir movement messages for easier following where
9493 the build process currently stays (more verbose then standard Make, less
9494 verbose than GNU make), same style to comments in the Configure script,
9495 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
9497 *) Add the new ApacheBench program "ab" to src/support/: This is derived
9498 from the ZeusBench benchmarking program and can be used to determine the
9499 response performance of an Apache installation. This version is
9500 officially licensed with Zeus Technology, Ltd. See the license agreement
9501 statements in <199803171224.NAA24547 en1.engelschall.com> in apache-core.
9502 [Ralf S. Engelschall]
9504 *) API: Various core functions that are definately not part of the API
9505 have been made static, and a few have been marked API_EXPORT. Still
9506 more have been marked CORE_EXPORT and are not intended for general
9507 use by modules. [Doug MacEachern, Dean Gaudet]
9509 *) mod_proxy was not clearing the Proxy-Connection header from
9510 requests; now it does. This did not violate any spec, however
9511 causes poor interactions when you are talking to remote proxies.
9512 [Marc Slemko] PR#1741
9514 *) Various cleanups to the command line interface and manual pages.
9515 [Ralf S. Engelschall]
9517 *) cfg_getline() was not properly handling lines that did not end
9518 with a line termination character. [Marc Slemko] PR#1869, 1909
9520 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
9522 *) Clean up some undocumented behavior of mod_setenvif related to
9523 "merging" two SetEnvIf directives when they match the same header
9524 and regex. Document that mod_setenvif will perform comparisons in
9525 the order they appear in the config file. Optimize mod_setenvif by
9526 doing more work at config time rather than at runtime.
9529 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
9530 to allow for modules to overrule them and to reduce redefinition
9531 warnings [Jim Jagielski]
9533 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
9536 *) Making the hard-coded cross-module function call mime_find_ct() (from
9537 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
9538 checking is really called even for proxy requests except for URLs with
9539 HTTP schemes (because there we can optimize by not running the type
9540 checking hooks due to the fact that the proxy gets the MIME Content-type
9541 from the remote host later). This change cleans up mod_mime by removing
9542 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
9543 especially unbundles mod_proxy and mod_mime. This way they both now can
9544 be compiled as shared objects and are no longer tied together.
9545 [Ralf S. Engelschall]
9547 *) util.c cleanup and speedup. [Dean Gaudet]
9549 *) API: Clarification, pstrndup() will always copy n bytes of the source
9550 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
9552 *) Mark module command_rec and handler_rec structures const so that they
9553 end up in the read-only data section (and are friendlier to systems
9554 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
9556 *) Add check to the "Port" directive to make sure the specified
9557 port is in the appropriate range. [Ben Hyde]
9559 *) Performance improvements to invoke_handler().
9560 [Dmitry Khrustalev <dima bog.msu.su>]
9562 *) Added support for building shared objects even for library-style modules
9563 (which are built from more than one object file). This now provides the
9564 ability to build mod_proxy as a shared object module. Additionally
9565 modules like mod_example are now also supported for shared object
9566 building because the generated Makefiles now no longer assume there is at
9567 least one statically linked module. [Ralf S. Engelschall]
9569 *) API: Clarify usage of content_type, handler, content_encoding,
9570 content_language and content_languages fields in request_rec. They
9571 must always be lowercased; and the strings pointed to shouldn't
9572 be modified (you must copy them to modify them). Fix a few bugs
9573 related to this. [Dean Gaudet]
9575 *) API: Clarification: except for RAW_ARGS, all command handlers can
9576 treat the char * parameters as permanent, and modifiable. There
9577 is no need to pstrdup() them. Clean up some needless pstrdup().
9580 *) Now mod_so keeps track of which module shared objects with which names
9581 are loaded and thus avoids multiple loading and unloading and irritating
9582 error_log messages. [Ralf S. Engelschall]
9584 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
9585 environment variable in the apache core. But that tweaking interferes
9586 with mod_setenv. So don't tweak if the user has specified an explicit
9587 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888
9589 *) rputs() did not calculate r->sent_bodyct properly.
9590 [Siegmund Stirnweiss <siegst kat.ina.de>] PR#1900
9592 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
9593 name, or left unset if this value is unavailable. Apache was setting
9594 it to the IP address when unavailable.
9595 [Tony Finch <fanf demon.net>] PR#1925
9597 *) Various improvements to the configuration and build support for compiling
9598 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
9599 OSF1 support with GCC and vendor compilers was added. This way shared
9600 object support is now provided out-of-the-box for FreeBSD, Linux,
9601 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
9602 [Ralf S. Engelschall]
9604 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
9605 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
9606 and USE_OS2_SCOREBOARD. [Dean Gaudet]
9608 *) Fix one more special locking problem for RewriteMap programs in
9609 mod_rewrite: According to the documentation of flock(), "Locks are on
9610 files, not file descriptors. That is, file descriptors duplicated
9611 through dup(2) or fork(2) do not result in multiple instances of a lock,
9612 but rather multiple references to a single lock. If a process holding a
9613 lock on a file forks and the child explicitly unlocks the file, the
9614 parent will lose its lock.". To overcome this we have to make sure the
9615 RewriteLock file is opened _AFTER_ the childs were spawned which is now
9616 the case by opening it in the child_init instead of the module_init API
9617 hook. [Ralf S. Engelschall] PR#1029
9619 *) Change to Location and LocationMatch semantics. LocationMatch no
9620 longer lets a single slash match multiple adjacent slashes in the
9621 URL. This change is for consistency with RewriteRule and
9622 AliasMatch. Multiple slashes have meaning in URLs that they do
9623 not have in (some) filesystems. Location on the other hand can
9624 be considered a shorthand for a more complicated regex, and it
9625 does match multiple slashes with a single slash -- which is
9626 also consistent with the Alias directive.

9629 *) Fix bug with mod_mime_magic causing certain files, including files
9630 of length 0, to result in no response from the server.
9633 *) The Configure script now generates src/include/ap_config.h which
9634 contains the set of defines used when Apache is compiled on a platform.
9635 This file can then be included by external modules before including
9636 any Apache header files in case they are being built separately from
9637 Apache. Along with this change, a couple of minor changes were
9638 made to make Apache's #defines coexist peacefully with any autoconf
9639 defines an external module might have. [Rasmus Lerdorf]
9641 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9642 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9643 chance by the API to initialize its per-server configuration and thus
9644 receives the wrong one from the main server. This is now avoided by
9645 remembering the server together with the config structure while
9646 configuring and later assuming there is no config when we see a
9647 difference between the remembered server and the one calling us.
9648 [Ralf S. Engelschall] PR#1790
9650 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9651 is automatically disabled under configure time when the dbm_xxx functions
9652 are not available. Second, two heavy source code errors in the DBM
9653 support code were fixed. This makes DBM RewriteMap's usable again after
9654 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9656 *) Now all configuration files support Unix-style line-continuation via
9657 the trailing backslash ("\") character. This enables us to write down
9658 complex or just very long directives in a more readable way. The
9659 backslash character has to be really the last character before the
9660 newline and it has not been prefixed by another (escaping) backslash.

9675 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
9676 depending on the rev of Solaris and what mixture of modules
9677 are in use. So it has been disabled, and Solaris is back to
9678 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9679 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9680 up static content only servers. Or it may fail unpredictably.

9683 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9686 *) API: Rewrite of absoluteURI handling, and in particular how
9687 absoluteURIs match vhosts. Unless a request is a proxy request, a
9688 "http://host" url is treated as if a similar "Host:" header had been
9689 supplied. This change was made to support future HTTP/1.x protocols
9690 which may require clients to send absoluteURIs for all requests.
9692 In order to achieve this change subtle changes were made to the API. In a
9693 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9694 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9695 by the core, modules must set it during the post_read_request or
9696 translate_names phase.
9698 Plus changes to the virtualhost test suite for absoluteURI testing.
9700 This fixes several bugs with the proxy proxying requests to vhosts
9701 managed by the same httpd.
9704 *) API: Cleanup of code in http_vhost.c, and remove vhost matching

9722 *) API: A new source module main/util_uri.c; It contains a routine
9723 parse_uri_components() and friends which breaks a URI into its component
9724 parts. These parts are stored in a uri_components structure called
9725 parsed_uri within each request_rec, and are available to all modules.
9726 Additionally, an unparse routine is supplied which re-assembles the URI
9727 components back to an URI, optionally hiding the username:password@ part
9728 from ftp proxy requests, and other useful routines. Within the structure,
9729 you find on a ready-for-use basis:
9730 scheme; /* scheme ("http"/"ftp"/...) */
9731 hostinfo; /* combined [user[:password]@]host[:port] */
9732 user; /* user name, as in http://user:passwd@host:port/ */
9733 password; /* password, as in http://user:passwd@host:port/ */
9734 hostname; /* hostname from URI (or from Host: header) */

9737 query; /* Everything after a '?' in the path, if present */
9738 fragment; /* Trailing "#fragment" string, if present */
9739 This is meant to serve as the platform for *BIG* savings in
9740 code complexity for the proxy module (and maybe the vhost logic).
9743 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and

9760 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
9761 server to bind to port 0 rather than 80. [Dean Gaudet]
9763 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
9764 (like SunOS and FreeBSD) which don't accept the locking of pipes
9765 directly. A new directive RewriteLock is introduced which can be used to
9766 setup a separate locking file which then is used for synchronization.

9769 *) WIN32: The server root is obtained from the registry key
9770 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently
9771 "1.3 beta"), unless overridden by the -d command line flag. The
9772 value is stored by running "apache -i -d serverroot". [Paul Sutton]

9781 *) The mod_setenvif BrowserMatch backwards compatibility command did not
9782 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
9784 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
9785 type but with a special post-processing for the looked-up value: It
9786 parses it into alternatives according to `|' chars and then only one
9787 particular alternative is chosen randomly (this is an essential
9788 functionality needed for balancing between backend-servers when using
9789 Apache as a Reverse Proxy. The looked up value here is a list of
9790 servers). Second, `int' with the built-in maps named `tolower' and
9791 `toupper' which can be used to map URL parts to a fixed case (this is an
9792 essential feature to fix the case of server names when doing mass
9793 virtual-hosting with the help of mod_rewrite instead of using
9794 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
9795 Jay Soffian <jay cimedia.com>] PR#1631
9797 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
9798 This directive lets Apache adjust the URL in Location-headers on HTTP
9799 redirect responses sent by the remote server. This way the virtually
9800 mapped area is no longer left on redirects and thus by-passed which is
9801 especially essential when running Apache as a reverse proxy.

9804 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
9805 hidden. [Alvaro Martinez Echevarria]
9807 *) Apache will, when started with the -X (single process) debugging flag,
9808 honor the SIGINT or SIGQUIT signals again now. This capability got lost
9809 a while ago during OS/2 signal handling changes.

9844 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
9845 effect. Work around it by using RLIMIT_AS for the RLimitMEM

9899 *) Sort out problems with canonical filename handling happening too late.
9900 [Dean Gaudet, Ben Laurie]
9902 Changes with Apache 1.3b4
9904 *) The module structure was modified to include a *dynamic_load_handle
9905 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
9906 has been bumped accordingly. [Paul Sutton]
9908 *) All BrowserMatch directives mentioned in
9909 htdocs/manual/known_client_problems.html are in the default
9910 configuration files. [Lars Eilebrecht]
9912 *) MiNT port update. [Jan Paul Schmidt]
9914 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
9915 equivalent, similarly for x-compress and compress. Apache
9916 now ignores a leading x- when comparing encodings. It also
9917 preserves the encoding the client requests (for example if
9918 it requests x-gzip, then Apache will respond with x-gzip
9919 in the Content-Encoding header).
9920 [Ronald Tschalaer <Ronald.Tschalaer psi.ch>] PR#1772
9922 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
9924 *) Added mod_so module to support dynamic loading of modules on Unix
9925 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
9926 instead of AddModule in Configuration to build shared modules
9927 [Sameer Parekh, Paul Sutton]
9929 *) Minor cleanups to r->finfo handling in some modules.
9932 *) Abstract read()/write() to ap_read()/ap_write().
9933 Makes it easier to add other types of IO code such as SFIO.
9936 *) API: Generalize default_port manipulations to make support of
9937 different protocols easier. [Ben Laurie, Randy Terbush]
9939 *) There are many cases where users do not want Apache to form
9940 self-referential urls using the "canonical" ServerName and Port.
9941 The new UseCanonicalName directive (default on), if set to off
9942 will cause Apache to use the client-supplied hostname and port.
9943 API: Part of this change required a change to the construct_url()
9944 prototype; and the addition of get_server_name() and
9946 [Michael Douglass <mikedoug texas.net>, Dean Gaudet]
9947 PR#315, 459, 485, 1433
9949 *) Yet another rearrangement of the source tree.. now all the common
9950 header files are in the src/include directory. The -Imain -Iap
9951 references in Makefiles have been changed to the simpler -Iinclude
9952 instead. In addition to simplifying the build a little bit, this
9953 also makes it clear when a module is referencing something in a
9954 other than kosher manner (e.g., the proxy including mod_mime.h).
9955 Module-private header files (the proxy, mod_mime, the regex library,
9956 and mod_rewrite) have not been moved to src/include; nor have
9957 the OS-abstraction files. [Ken Coar]
9959 *) Fix a bug where r->hostname didn't have the :port stripped
9960 from it. [Dean Gaudet]
9962 *) Tweaked the headers_out table size, and the subprocess_env
9963 table size guess in rename_original_environment(). Added
9964 MAKE_TABLE_PROFILE which can help discover make_table()
9965 calls that use too small an initial guess, see alloc.c.
9968 *) Options and AllowOverride weren't properly merging in the main
9969 server setting inside vhosts (only an issue when you have no
9970 <Directory> or other section containing an Options that affects
9971 a request). Options +foo or -foo in the main_server wouldn't
9972 affect the main_server's lookup defaults. [Dean Gaudet]
9974 *) Variable 'cwd' was being used pointlessly before being set.
9977 *) r->allowed handling cleaned up in the standard modules.
9980 *) Some case-sensitivity issues cleaned up to be consistent with
9981 RFC2068. [Dean Gaudet]
9983 *) SIGURG doesn't exist everywhere.
9984 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
9986 *) mod_unique_id was erroneously generating a second unique id when
9987 an internal redirect occured. Such redirects occur, for example,
9988 when processing a DirectoryIndex match. [Dean Gaudet]
9990 *) API: table_add, table_merge, and table_set include implicit pstrdup()
9991 of the key and value. But in many cases this is not required
9992 because the key/value is a constant, or the value has been built
9993 by pstrcat() or other similar means. New routines table_addn,
9994 table_mergen, and table_setn have been added to the API, these
9995 routines do not pstrdup() their arguments. The core code and
9996 standard modules were changed to take advantage of these routines.
9997 The resulting server is up to 20% faster in some situations.
9999 Note that it is easy to get code subtly wrong if you pass a key/value
10000 which is in a pool other than the pool of the table. The only
10001 safe thing to do is to pass key/values which are in the pool of
10002 the table, or in one of the ancestors of the pool of the table.
10003 i.e. if the table is part of a subrequest, a value from the main
10004 request's pool is OK since the subrequest pool is a sub_pool of the
10005 main request's pool (and therefore has a lifespan at most as long as
10006 the main pool). There is debugging code which can detect improper
10007 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
10008 [Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet]
10010 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
10011 which don't exist on disk more gracefully; handles vhosts properly.
10012 Update documentation to reflect the code -- if there's no
10013 MimeMagicFile directive then the module is not enabled.
10016 *) PORT: Some older *nix dialects cannot automatically start scripts
10017 which begin with a #! interpreter line (the shell starts the scripts
10018 appropriately on these platforms). Apache now supports starting of
10019 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
10020 [Martin Kraemer, with code from Peter Wemm <peter zeus.dialix.oz.au>
10023 *) API: "typedef array_header table" removed from alloc.h, folks should
10024 have been writing to use table as if it were an opaque type, but even
10025 some standard modules got this wrong. By changing the definition
10026 to "typedef struct table table" module authors will receive compile
10027 time warnings that they're doing the wrong thing. This change
10028 facilitates future changes with more sophisticated table
10029 structures. Specifically, module authors should be using table_elts()
10030 to get access to an array_header * for the table. [Dean Gaudet]
10032 *) API: Renamed new_connection() to avoid namespace collision with LDAP
10033 library routines. [Ken Coar, Rasmus Lerdorf]
10035 *) WIN32: mod_speling is now available on the Win32 platform.
10038 *) For clarity the following compile time definition was changed:
10040 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
10042 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
10043 and not be a general notice that the OS has mmap(). Now the
10044 HAVE_MMAP/SHMGET #defines strictly are informational that the
10045 OS has that method of shared memory; the type to use for
10046 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
10047 and USE_SHMGET_SCOREBOARD). This allows outside modules to
10048 determine if shared memory is available and allows Apache
10049 to determine the best method to use for the scoreboard.
10052 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
10053 as do various earlier versions. It should be safe on all versions.
10054 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
10055 the slack code. A few other cleanups for Unixware.

10058 *) PORT: A/UX can handle single-listen accepts without mutex
10059 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
10061 *) When die() happens we need to eat any request body if one exists.
10062 Otherwise we can't continue with a keepalive session. This shows up
10063 as a POST problem with MSIE 4.0, typically against pages which are
10064 authenticated. [Roy Fielding] PR#1399
10066 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
10067 header will be passed to CGIs. This is generally a security hole, so
10068 it's not a default. [Marc Slemko] PR#549

10077 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
10078 The choice of flock vs. fcntl was made based on timings which showed that
10079 even on non-NFS, non-exported filesystems fcntl() was an order of
10080 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
10081 that single socket users will see no difference. [Dean Gaudet] PR#467
10083 *) "File does not exist" error message was erroneously including the
10084 errno. [Marc Slemko]
10086 *) Improve the warning message generated when a client drops the

10103 *) Some const declarations in mod_imap.c that were added for debugging
10104 purposes caused some compilers heartburn without adding any
10105 significant value, so they've been removed. [Ken Coar]
10107 *) The src/main/*.h header files have had #ifndef wrappers added to
10108 insulate them against duplicate calls if they get included through
10109 multiple paths (e.g., in .c files as well as other .h files).
10112 *) The libap routines now have a header file for their prototypes,
10113 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
10115 *) mod_autoindex with a plaintext header file would emit the <PRE>
10116 start-tag before the HTML preamble, rather than after the preamble
10117 but before the header file contents. [John Van Essen <jve gamers.org>]
10120 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
10121 only an issue on systems without a MAXDNAME define or where
10122 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
10124 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
10125 is used to read various types of files such as htaccess and
10126 htpasswd files. [Marc Slemko]
10128 *) SECURITY: Ensure that the buffer returned by ht_time is always
10129 properly null terminated. [Marc Slemko]

10139 [<Ronald.Tschalaer psi.ch>] PR#1666
10141 *) For maximum portability, the environment passed to CGIs should
10142 only contain variables whose names match the regex
10143 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
10144 underscores over any character outside the regex. This
10145 affects HTTP_* variables, in a way that should be backward
10146 compatible for all the standard headers; and affects variables
10147 set with SetEnv/BrowserMatch and similar directives.

10233 *) send_fd_length() did not calculate total_bytes_sent properly.
10234 [Ben Reser <breser regnow.com>] PR#1366
10236 *) The bputc() macro was not properly integrated with the chunking
10237 code; in many cases modules using bputc() could cause completely
10238 bogus chunked output. (Typically this will show up as problems
10239 with Internet Explorer 4.0 reading a page, but other browsers
10240 having no problem.) [Dean Gaudet]
10242 *) Create LARGE_WRITE_THRESHOLD define which determines how many
10243 bytes have to be supplied to bwrite() before it will consider
10244 doing a writev() to assemble multiple buffers in one system
10245 call. This is critical for modules such as mod_include,
10246 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
10247 strings in some cases. The result would be extra effort
10248 setting up writev(), and in many cases extra effort building
10249 chunks. The default is 31, it can be overriden at compile
10250 time. [Dean Gaudet]

10267 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
10268 useful, and isn't what the standards require. Now it returns 0
10269 and writes nothing. [Dean Gaudet]
10271 *) When an error occurs in fcntl() locking suggest the user look up
10272 the docs for LockFile. [Dean Gaudet]
10274 *) Eliminate some dead code from writev_it_all().
10275 [Igor Tatarinov <tatarino prairie.NoDak.edu>]
10277 *) mod_autoindex had an fread() without checking the result code.
10278 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"
10279 (note the missing closing paren) properly. [Dean Gaudet]
10281 *) It appears the "257th byte" bug (see

10318 now have a title in which the path components are clickable and allow
10319 quick navigation to the clicked-on directory on the currently listed
10320 ftp server. This also fixes a bug where the ".." directory links would
10321 sometimes refer to the wrong directory. [Martin Kraemer]

10358 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
10359 This turns out to be a bug in Winsock - select() doesn't always
10360 return the correct status. [Ben Laurie]
10362 *) Directives owned by http_core can now use the new check_cmd_context()
10363 routine to ensure that they're not being used within a container
10364 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
10366 *) PORT: Recent changes made it necessary to add explicit prototype
10367 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
10369 *) It was necessary to distinguish between resources which are
10370 allocated in the parent, for cleanup in the parent, and resources
10371 which are allocated in each child, for cleanup in each child.
10372 A new pool was created which is passed to the module child_init
10373 and child_exit functions; modules are free to register per-child
10374 cleanups there. This fixes a bug with reliable piped logs.
10377 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
10378 unless it was also doing FancyIndexes, but it displayed the
10379 HeaderName file at the top under all circumstances. It now shows
10380 the ReadmeName file for simple indices, too, as it should.
10383 *) http_core was mmap()ing even in cases where it wasn't going to
10384 read the file. [Ben Hyde <bhyde gensym.com>]
10386 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
10387 Now the rewriting engine (the heart of mod_rewrite) is organized more
10388 straight-forward, first time well documented and reduced to the really
10389 essential parts. All redundant cases were stripped off and processing now
10390 is the same for both per-server and per-directory context with only a
10391 minimum difference (the prefix stripping in per-dir context). As a
10392 side-effect some subtle restrictions and two recently discovered problems
10393 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
10394 context and restrictions on the substitution URL on redirects.
10395 Additionally some minor source cleanups were done.

10402 *) If ap_slack fails to allocate above the low slack line it's a good

10550 Changes with Apache 1.3b2 (there is no 1.3b1)
10552 *) TestCompile was not passing $LIBS [Dean Gaudet]
10554 *) Makefile.tmpl was not using $CFLAGS in the link phase.
10557 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
10558 rudimentary memory debugger which can be used on live servers with
10559 low impact -- it sets all allocated and freed memory bytes to 0xa5.
10560 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
10561 and free() for each object. This is far more expensive and should
10562 only be used for testing with tools such as Electric Fence and
10563 Purify. See main/alloc.c for more details. [Dean Gaudet]
10565 *) Configure uses a sh trap and didn't set its exitcode properly.
10566 [Dean Gaudet] PR#1159
10568 *) Yet another vhost revamp. Add the NameVirtualHost directive which
10569 explicitly lists the ip:port pairs that are to be used for name-vhosts.
10570 From a given ip:port, regardless what the Host: header is, you can
10571 only reach the vhosts defined on that ip:port. The precedence of
10572 vhosts was reversed to match other precedences in the config --
10573 the earlier vhosts override the later vhosts. All vhost matching was
10574 moved into http_vhost.[ch]. [Dean Gaudet]
10576 *) ap_inline can be used to force inlining. GNUC __attribute__() can
10577 be used for whatever reason is appropriate (i.e. format() warnings
10578 for printf style functions). Both are enabled only with
10579 gcc >= 2.7.x (so that we have fewer support issues with older
10580 versions). [Dean Gaudet]
10582 *) Fix support for Proxy Authentication (we were testing the response
10583 status too early). [Marc Slemko]
10585 *) CoreDumpDirectory directive directs where the core file is
10586 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
10587 received. [Marc Slemko, Dean Gaudet]

10590 [Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
10592 *) When booting, apache will now detach itself from stdin, stdout,
10593 and stderr. stderr will not be detached until after the config
10594 files have been read so you will be able to see initial error
10595 messages. After that all errors are logged in the error_log.
10596 This makes it more convenient to start apache via rsh, ssh,
10597 or crontabs. [Dean Gaudet] PR#523
10599 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10600 Also removed the auto-generated link to www.apache.org that was the
10601 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10603 *) send_fb would not detect aborted connections in some situations.
10606 *) mod_include would use uninitialized data when parsing certain
10607 expressions involving && and ||. [Brian Slesinsky] PR#1139
10609 *) mod_imap should only handle GET methods. [Jay Bloodworth]
10611 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10613 *) mod_autoindex improperly counted &escapes; as more than one
10614 character in the description. It also improperly truncated
10615 descriptions that were exactly the maximum length.
10618 *) RedirectMatch was not properly escaping the result (PR#1155). Also
10619 "RedirectMatch /advertiser/(.*) $1" is now permitted.
10622 *) mod_include now uses symbolic names to check for request success
10623 and return HTTP errors, and correctly handles all types of
10624 redirections (previously it only did temporary redirect correctly).
10625 [Ken Coar, Roy Fielding]
10627 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10628 r->filename. Since those two are meant to be in sync with each other
10629 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]

10641 *) Fixed error in proxy_util.c when looping through multiple host IP
10642 addresses. [Lars Eilebrecht] PR#974
10644 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10645 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10646 bytes before writing, but it will never split a log entry across a
10647 buffer boundary. [Dean Gaudet]
10649 *) API: the short_score record has been split into two pieces, one which
10650 the parent writes on, and one which the child writes on. As part of
10651 this change the get_scoreboard_info() function was removed, and
10652 scoreboard_image was exported. This change fixes a race condition
10653 in file based scoreboard systems, and speeds up changes involving the
10654 scoreboard in earlier 1.3 development. [Dean Gaudet]
10656 *) API: New register_other_child() API (see http_main.h) which allows
10657 modules to register children with the parent for maintenance. It
10658 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10660 *) API: New piped_log API (see http_log.h) which implements piped logs,
10661 and will use register_other_child to implement reliable piped logs
10662 when it is available. The reliable piped logs part can be disabled
10663 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10664 logs is only available on Unix. [Dean Gaudet]
10666 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10667 meets_conditions(). This allows conditional HTTP selection to be
10668 handled separately from the storing of the header fields, and provides
10669 the ability for CGIs to set their own ETags for conditional checking.
10670 [Ken Coar, Roy Fielding] PR#895
10672 *) Changes to mod_log_config to allow naming of format strings.
10673 Format nicknames are defined with "LogFormat fmt nickname", and can

10677 *) New module, "mod_speling", which can help find files even when
10678 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
10680 *) API: New function child_terminate() triggers the child process to
10681 exit, while allowing the child finish what it needs to for the
10682 current request first.

10688 *) *Really* disable all mod_rewrite operations if the engine is off.
10689 Some things (like RewriteMaps) were checked/performed even if they
10690 weren't supposed to be. [Ken Coar] PR #991
10692 *) Implement a new timer scheme which eliminates the need to call alarm() all
10693 the time. Instead a counter in the scoreboard for each child is used to
10694 show when the child has made forward progress. The parent samples this
10695 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10696 progress has been made in the timeout period. This reduces the static
10697 request best-case syscall count to 22 from 29. This scheme is only
10698 used by systems with memory-based scoreboards. [Dean Gaudet]
10700 *) The proxy now properly handles CONNECT requests which are sent
10701 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10703 *) A script called apachectl has been added to the support
10704 directory. This script allows you to do things such as
10705 "apachectl start" and "apachectl restart" from the command
10706 line. [Marc Slemko]
10708 *) Modules and core routines are now put into libraries, which
10709 simplifies the link line tremendously (among other advantages).
10712 *) Some of the MD5 names defined in Apache have been renamed to have
10713 an `ap_' prefix to avoid conflicts with routines supplied by
10714 external libraries. [Ken Coar]
10716 *) Removal of mod_auth_msql.c from the distribution. There are many
10717 other options for databases today. Rather than offer one option,
10718 offer none at this time. mod_auth_msql and other SQL database
10719 authentication modules can be found at the Apache Module Registry.
10720 http://modules.apache.org/ It would be nice to offer a generic
10721 mod_auth_sql option in the near future.
10723 *) PORT: BeOS support added [Alexei Kosut]
10725 *) Configure no longer accepts the -make option, since it creates
10726 Makefile on the fly based on Makefile.tmpl and Configuration.
10728 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
10729 of forcibly killing off all its processes and exiting without
10730 cleaning up. [Alexei Kosut]
10732 *) API: A new field in the request_rec, r->mtime, has been added to
10733 avoid gratuitous parsing of date strings. It is intended to hold
10734 the last-modified date of the resource (if applicable). An
10735 update_mtime() routine has also been added to advance it if
10736 appropriate. [Roy Fielding, Ken Coar]
10738 *) SECURITY: If a htaccess file can not be read due to bad permissions,
10739 deny access to the directory with a HTTP_FORBIDDEN. The previous
10740 behavior was to ignore the htaccess file if it could not be read.
10741 This change may make some setups with unreadable htaccess files
10742 stop working. [Marc Slemko] PR#817
10744 *) Add aplog_error() providing a mechanism to define levels of
10745 verbosity to the server error logging. This addition also provides
10746 the ability to log errors using syslogd. Error logging is configurable
10747 on a per-server basis using the LogLevel directive. Conversion
10748 of log_*() in progress. [Randy Terbush]
10750 *) Further enhance aplog_error() to not log filename, line number, and
10751 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]

10754 converted to long ones. Backslashes are converted to forward
10755 slashes. Case is converted to lower. Parts of URLs that do not
10756 correspond to files are left completely alone. [Ben Laurie]

10768 *) Set r->headers_out when sending responses from the proxy.
10769 This fixes things such as the logging of headers sent from
10770 the proxy. [Marc Slemko] PR#659
10772 *) support/httpd_monitor is no longer distributed because the
10773 scoreboard should not be file based if at all possible. Use
10774 mod_status to see current server snapshot.
10776 *) (set_file_slot): New function, allowing auth directives to be
10777 independent of the server root, so the server documents can be
10778 moved to a different directory or machine more easily.
10779 [David J. MacKenzie]
10781 *) If no TransferLog is given explicitly, decline
10782 to log. This supports coexistence with other logging modules,
10783 such as the custom one that UUNET uses. [David J. MacKenzie]
10785 *) Check for titles in server-parsed HTML files.
10786 Ignore leading newlines and returns in titles. The old behavior
10787 of replacing a newline after <title> with a space causes the
10788 title to be misaligned in the listing. [David J. MacKenzie]
10790 *) Change mod_cern_meta to be configurable on a per-directory basis.
10791 [David J. MacKenzie]
10793 *) Add 'Include' directive to allow inclusion of configuration
10794 files within configuration files. [Randy Terbush]
10796 *) Proxy errors on connect() are logged to the error_log (nothing
10797 new); now they include the IP address and port that failed
10798 (*that's* new). [Ken Coar, Marc Slemko] PR#352
10800 *) Various architectures now define USE_MMAP_FILES which causes
10801 the server to use mmap() for static files. There are two
10802 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
10803 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
10804 number of bytes written in one cycle from a single mmap()d object,
10805 default 32768). [Dean Gaudet]
10807 *) API: Added post_read_request API phase which is run right after reading
10808 the request from a client, or right after an internal redirect. It is
10809 useful for modules setting environment variables that depend only on
10810 the headers/contents of the request. It does not run during subrequests
10811 because subrequests inherit pretty much everything from the main
10812 request. [Dean Gaudet]
10814 *) Added mod_unique_id which is used to generate a unique identifier for
10815 each hit, available in the environment variable UNIQUE_ID.
10818 *) init_modules is now called after the error logs have been opened. This
10819 allows modules to emit information messages into the error logs.
10822 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10823 information for case where proxy module is not available. [Marc Slemko]
10825 *) PORT: Apache has need for mutexes to serialize its children around
10826 accept. In prior versions either fcntl file locking or flock file
10827 locking were used. The method is chosen by the definition of
10828 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
10829 and FLOCK for flock(). New options have been added:
10830 - SYSVSEM to use System V style semaphores
10831 - PTHREAD to use POSIX threads (appears to work on Solaris only)
10832 - USLOCK to use IRIX uslock
10833 Based on timing various techniques, the following changes were made
10835 - Linux 2.x uses flock instead of fcntl
10836 - Solaris 2.x uses pthreads
10837 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
10838 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
10839 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
10840 Martijn Koster <m.koster pobox.com>]
10842 *) PORT: The semantics of accept/select make it very desirable to use
10843 mutexes to serialize accept when multiple Listens are in use. But
10844 in the case where only a single socket is open it is sometimes
10845 redundant to serialize accept(). Not all unixes do a good job with
10846 potentially dozens of children blocked on accept() on the same
10847 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
10848 the server will avoid serialization when listening on only one socket,
10849 and use serialization when listening on multiple sockets.
10850 [Dean Gaudet] PR#467
10852 *) Configure changes: TestLib replaced by TestCompile, which has
10853 some additional capability (such as doing a sanity check of
10854 the compiler and flags selected); the version of Solaris is now
10855 available via the #define value of SOLARIS2; IRIX n32bit libs
10856 now supported and selectable by new Configuration Rule: IRIXN32;
10857 We no longer default to -O2 optimization. [Jim Jagielski]
10859 *) Updated Configure: Configuration now uses AddModule to specify
10860 module source or binary file location, relative to src directory.
10861 Modules can be dropped into modules/extra, or in their own
10862 directory, and modules can come with a Makefile or Configure can
10863 create one. Modules can add compiler or library information to
10864 generated Makefiles. [Paul Sutton]
10866 *) Source core re-organisation: distributed modules are now in
10867 modules/standard. All other source code is in main. OS-specific
10868 code is in os/{unix,emx,win32} directories. [Paul Sutton]
10870 *) mod_browser has been removed, since it's replaced by mod_setenvif.
10873 *) Fix another long-standing bug in sub_req_lookup_file where it would
10874 happily skip past access checks on subdirectories looked up with
10875 relative paths. (It's used by mod_dir, mod_negotiation,
10876 and mod_include.) [Dean Gaudet]
10878 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
10879 N is the number of <Directory> sections, and M is the number of
10880 components in the filename of an object.
10882 To achieve this optimization the following config changes were made:
10883 - Wildcards (* and ?, not the regex forms) in <Directory>s,
10884 <Files>s, and <Location>s now treat a slash as a special
10885 character. For example "/home/*/public_html" previously would
10886 match "/home/a/andrew/public_html", now it only matches things
10887 like "/home/bob/public_html". This mimics /bin/sh behaviour.
10888 - It's possible now to use [] wildcarding in <Directory>, <Files>
10890 - Regex <Directory>s are applied after all non-regex <Directory>s.
10894 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
10895 and corrupted paths. [Dean Gaudet]
10897 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
10898 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
10899 be accessed now via backreferences $1..$9 in RewriteConds test-against
10900 strings in addition to RewriteRules subst string. Second the grouped
10901 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
10902 via backreferences %1..%9 both in following RewriteCond test-against
10903 strings and RewriteRules subst string. This provides maximum flexibility
10904 through the use of backreferences.
10905 Additionally the rewriting engine was cleaned up by putting common
10906 code to the new expand_backrefs_inbuffer() function.
10907 [Ralf S. Engelschall]
10909 *) When merging the main server's <Directory> and <Location> sections into
10910 a vhost, put the main server's first and the vhost's second. Otherwise
10911 the vhost can't override the main server. [Dean Gaudet] PR#717
10913 *) The <Directory> code would merge and re-merge the same section after
10914 a match was found, possibly causing problems with some modules.
10917 *) ip-based vhosts are stored and queried using a hashing function, which
10918 has been shown to improve performance on servers with many ip-vhosts.
10919 Some other changes had to be made to accommodate this:
10920 - the * address for vhosts now behaves like _default_
10921 - the matching process now is:
10922 - match an ip-vhost directly via hash (possibly matches main
10924 - if that fails, just pretend it matched the main server
10925 - if so far only the main server has been matched, perform
10926 name-based lookups (ServerName, ServerAlias, ServerPath)
10927 *only on name-based vhosts*
10928 - if they fail, look for _default_ vhosts
10929 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
10931 *) dbmmanage overhaul:
10932 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
10933 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
10934 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
10935 - provide better seed for rand
10936 - prompt for password as per getpass(3) (turn off echo, read from
10938 - use "newstyle" crypt based on $Config{osname} ($^O)
10939 - will not add a user if already in database, use new `update' command
10941 - added `check' command to check a users' password
10942 - added `import' command to convert existing password text-files or
10943 dbm files exported with `view'
10944 - more descriptive usage, general cleanup, 'use strict' clean, etc.
10947 *) Added psocket() which is a pool form of socket(), various places within
10948 the proxy weren't properly blocking alarms while registering the cleanup
10949 for its sockets. bclose() now uses pclose() and pclosesocket(). There
10950 was a bug where the client socket was being close()d twice due a still
10951 registered cleanup. [Dean Gaudet]
10953 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
10956 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
10957 [Jason Venner <jason idiom.com>] PR#667
10959 *) Enable ``=""'' for RewriteCond directives to match against
10960 the empty string. This is the preferred way instead of ``^$''.
10961 [Ralf S. Engelschall]
10963 *) Fixed an infinite loop in mod_imap for references above the server root
10964 [Dean Gaudet] PR#748
10966 *) mod_proxy now has a ReceiveBufferSize directive, similar to
10967 SendBufferSize, so that the TCP window can be set appropriately
10968 for LFNs. [Phillip A. Prindeville]
10970 *) mod_browser has been replaced by the more general mod_setenvif
10971 (courtesy of Paul Sutton). BrowserMatch* directives are still
10972 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
10973 UnSetEnvIfZero directives. [Ken Coar]
10975 *) "HostnameLookups double" forces double-reverse DNS to succeed in
10976 order for remote_host to be set (for logging, or for the env var
10977 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
10980 *) mod_access overhaul:
10981 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
10982 and cidr syntax (i.e. 10.1.0.0/16). PR#762
10983 - Critical path was sped up by pre-computing a few things at config time.
10984 - The undocumented syntax "allow user-agents" was removed,
10985 the replacement is "allow from env=foobar" combined with mod_browser.
10986 - When used with hostnames it now forces a double-reverse lookup
10987 no matter what the directory settings are. This double-reverse
10988 doesn't affect any of the other routines that use the remote
10989 hostname. In particular it's still passed to CGIs and the log
10990 without the double-reverse check. Related PR#860.
10993 *) When a large bwrite() occurs (larger than the internal buffer size),
10994 while there is already something in the buffer, apache will combine
10995 the large write and the buffer into a single writev(). (This is
10996 in anticipation of using mmap() for reading files.)
10999 *) In obscure cases where a partial socket write occurred while chunking,
11000 Apache would omit the chunk header/footer on the next block. Cleaned
11001 up other bugs/inconsistencies in error conditions in buff.c. Fixed
11002 a bug where a long pause in DNS lookups could cause the last packet
11003 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
11005 *) API: Added child_exit function to module structure. This is called
11006 once per "heavy-weight process" just before a server child exit()'s
11007 e.g. when max_requests_per_child is reached, etc.
11008 [Doug MacEachern, Dean Gaudet]
11010 *) mod_include cleanup showed that handle_else was being used to handle
11011 endif. It didn't cause problems, but it was cleaned up too.
11014 *) mod_cern_meta would attempt to find meta files for the directory itself
11015 in some cases, but not in others. It now avoids it in all cases.
11018 *) mod_mime_magic would core dump if there was a decompression error.
11019 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
11021 *) PORT: some variants of DGUX require -lsocket -lnsl
11022 [Alexander L Jones <alex systems-options.co.uk>] PR#732
11024 *) mod_autoindex now allows sorting of FancyIndexed directory listings
11025 by the various fields (name, size, et cetera), either in ascending
11026 or descending order. Just click on the column header. [Ken Coar]
11028 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
11029 CPUs like the Alpha. Apache still stores ints in pointers, but that's
11030 the relatively safe direction. [Dean Gaudet] PR#344
11032 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
11033 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
11035 *) child_main avoids an unneeded call to select() when there is only one
11036 listening socket. [Dean Gaudet]
11038 *) In the event that the server is starved for idle servers it will
11039 spawn 1, then 2, then 4, ..., then 32 servers each second,
11040 doubling each second. It'll also give a warning in the errorlog
11041 since the most common reason for this is a poor StartServers
11042 setting. The define MAX_SPAWN_RATE can be used to raise/lower
11043 the maximum. [Dean Gaudet]
11045 *) Apache now provides an effectively unbuffered connection for
11046 CGI scripts. This means that data will be sent to the client
11047 as soon as the CGI pauses or stops output; previously, Apache would
11048 buffer the output up to a fixed buffer size before sending, which
11049 could result in the user viewing an empty page until the CGI finished
11050 or output a complete buffer. It is no longer necessary to use an
11051 "nph-" CGI to get unbuffered output. Given that most CGIs are written
11052 in a language that by default does buffering (e.g. perl) this
11053 shouldn't have a detrimental effect on performance.
11055 "nph-" CGIs, which formerly provided a direct socket to the client
11056 without any server post-processing, were not fully compatible with
11057 HTTP/1.1 or SSL support. As such they would have had to implement
11058 the transport details, such as encryption or chunking, in order
11059 to work properly in certain situations. Now, the only difference
11060 between nph and non-nph scripts is "non-parsed headers".
11061 [Dean Gaudet, Sameer Parekh, Roy Fielding]
11063 *) If a BUFF is switched from buffered to unbuffered reading the first
11064 bread() will return whatever remained in the buffer prior to the
11065 switch. [Dean Gaudet]
11067 Changes with Apache 1.3a1
11069 *) Added another Configure helper script: TestLib. It determines
11070 if a specified library exists. [Jim Jagielski]
11072 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
11073 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
11076 *) PORT: Some architectures use size_t for various lengths in network
11077 functions such as accept(), and getsockname(). The definition
11078 NET_SIZE_T is used to control this. [Dean Gaudet]
11080 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
11081 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
11082 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
11084 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
11085 [Igor N Kovalenko <infoh mail.wplus.net>]
11087 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11088 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11089 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11090 [Dean Gaudet] related PR#875
11092 *) API: Correct child_init() slot declaration from int to void, to
11093 match the init() declaration. Update mod_example to use the new
11096 *) added transport handle slot (t_handle) to the BUFF structure
11099 *) get_client_block() returns wrong length if policy is
11100 REQUEST_CHUNKED_DECHUNK.
11101 [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#815
11103 *) Support the image map format of FrontPage. For example:

11108 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
11110 *) AddModuleInfo directive for mod_info which allows you to annotate
11111 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
11113 *) Added NoProxy directive to avoid using ProxyRemote for selected
11114 addresses. Added ProxyDomain directive to cause unqualified
11115 names to be qualified by redirection.
11116 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
11118 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
11119 header to the remote host in the proxy. [Sameer Parekh and
11122 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
11123 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
11124 URLs, fixed rewritelog(), fixed forced response code handling on
11125 redirects from within .htaccess files, disabled pipe locking under
11126 braindead SunOS 4.1.x, allow env variables to be set even on rules with
11127 no substitution, bugfixed situations where HostnameLookups is off, made
11128 mod_rewrite more thread-safe for NT port and fixed problem when creating
11129 an empty query string via "xxx?".
11130 This update also removes the copyright of Ralf S. Engelschall,
11131 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
11132 exclusively copyrighted by the Apache Group now. This happened because
11133 the author now has gifted mod_rewrite exclusively to the Apache Group and
11134 no longer maintains an external version.
11135 [Ralf S. Engelschall]
11137 *) API: Added child_init function to module structure. This is called
11138 once per "heavy-weight process" before any requests are handled.
11139 See http_config.h for more details. [Dean Gaudet]
11141 *) Anonymous_LogEmail was logging on each subrequest.
11142 [Dean Gaudet] PR#421, 868
11144 *) API: Added is_initial_req() which tests if the request being
11145 processed is the initial request, or a subrequest.
11148 *) Extended SSI (mod_include) now handles additional relops for
11149 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
11151 *) Configure fixed to correctly propagate user-selected options and
11152 settings (such as CC and OPTIM) to Makefiles other than
11153 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
11155 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
11156 directory indices to start with the contents of the HeaderName file
11157 if there is one. If there isn't one, the behaviour is unchanged.
11158 [Ken Coar, Roy Fielding, Andrey A. Chernov]
11160 *) WIN32: Modules can now be dynamically loaded DLLs using the
11161 LoadModule/LoadFile directives. Note that module DLLs must be
11162 compiled with the multithreaded DLL version of the runtime library.
11163 [Alexei Kosut and Ben Laurie]
11165 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
11166 This allows the admin to completely remove automatic indexing
11167 from the server, while still supporting the basic functions of
11168 trailing-slash redirects and DirectoryIndex files. Note that if
11169 you're carrying over an old Configuration file and you use directory
11170 indexing then you'll want to add:
11172 Module autoindex_module mod_autoindex.o
11174 before mod_dir in your Configuration. [Dean Gaudet]
11176 *) popendir/pclosedir created to properly protect directory scanning.
11177 [Dean Gaudet] PR#525
11179 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
11180 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
11181 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
11184 *) The AccessFileName directive can now take more than one filename.
11185 ["Lou D. Langholtz" <ldl usi.utah.edu>]
11187 *) The new mod_mime_magic can be used to "magically" determine the type
11188 of a file if the extension is unknown. Based on the unix file(1)
11189 command. [Ian Kluft <ikluft cisco.com>]
11191 *) We now determine and display the time spent processing a
11192 request if desired. [Jim Jagielski]
11194 *) mod_status: PID field of "dead" child slots no longer displays
11195 main httpd process's PID. [Jim Jagielski]
11197 *) Makefile.nt added - to build all the bits from the command line:
11198 nmake -f Makefile.nt
11199 Doesn't yet work properly. [Ben Laurie]
11201 *) Default text of 404 error is now "Not Found" rather than the
11202 potentially misleading "File Not Found". [Ken Coar]
11204 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
11205 for the net if we require people that actually need this data to
11206 enable it. [Linus Torvalds]
11208 *) directory_walk() is an expensive function, keep a little more state to
11209 avoid needless string counting. Add two new functions make_dirstr_parent
11210 and make_dirstr_prefix which replace all existing uses of make_dirstr.
11211 The new functions are a little less general than make_dirstr, but
11212 work more efficiently (less memory, less string counting).
11215 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
11216 to LDFLAGS) to avoid complications with lex rules in make files.
11217 [Dean Gaudet] PR#372
11219 *) run_method optimized to avoid needless scanning over NULLs in the
11220 module list. [Dean Gaudet]
11222 *) Revamp of (unix) scoreboard management code such that it avoids
11223 unnecessary traversals of the scoreboard on each hit. This is
11224 particularly important for high volume sites with a large
11225 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
11226 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
11227 httpd.h. [Dean Gaudet]
11229 *) In configurations using multiple Listen statements it was possible for
11230 busy sockets to starve other sockets of service. [Dean Gaudet]
11232 *) Added hook so standalone_main can be replaced at compile time
11233 (define STANDALONE_MAIN)
11236 *) Lowest-level read/write functions in buff.c will be replaced with
11237 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
11238 compile time. The default sfio discipline will behave as apache
11239 would without sfio compiled in.
11242 *) Enhance UserDir directive (mod_userdir) to accept a list of
11243 usernames for the 'disable' keyword, and add 'enable user...' to
11244 selectively *en*able userdirs if they're globally disabled.
11247 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
11248 will work with Netscape dbm files. (dbmmanage will probably not
11249 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
11251 *) Add a ListenBacklog directive to control the backlog parameter
11252 passed to listen(). Also change the default to 511 from 512.
11255 *) API: A new handler response DONE which informs apache that the
11256 request has been handled and it can finish off quickly, similar to
11257 how it handles errors. [Rob Hartill]
11259 *) Turn off chunked encoding after sending terminating chunk/footer

11262 *) mod_expire also issues Cache-Control: max-age headers.
11265 *) API: Added kill_only_once option for free_proc_chain so that it won't
11266 aggressively try to kill off specific children. For fastcgi.

11269 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
11271 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
11272 When used together, these cause mod_dir to emit HEIGHT and WIDTH
11273 attributes in the FancyIndexing IMG tags. [Ken Coar]
11275 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
11277 *) PORT: Added Windows NT support
11278 [Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
11280 Changes with Apache 1.2.6
11282 *) mod_include when using XBitHack Full would send ETags in addition to
11283 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
11284 [Dean Gaudet] PR#1133
11286 *) SECURITY: When a client connects to a particular port/addr, and
11287 gives a Host: header ensure that the virtual host requested can
11288 actually be reached via that port/addr. [Ed Korthof <ed organic.com>]
11290 *) Support virtual hosts with wildcard port and/or multiple ports
11291 properly. [Ed Korthof <ed organic.com>]
11293 *) Fixed some case-sensitivity issues according to RFC2068.
11296 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
11297 and mod_include.c. [Dean Gaudet]
11299 *) Variable 'cwd' was being used pointlessly before being set.
11302 *) SIGURG doesn't exist on all platforms.
11303 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
11305 *) When an error occurs during a POST, or other operation with a
11306 request body, the body has to be read from the net before allowing
11307 a keepalive session to continue. [Roy Fielding] PR#1399
11309 *) When an error occurs in fcntl() locking suggest the user look up
11310 the docs for LockFile. [Dean Gaudet]
11312 *) table_set() and table_unset() did not deal correctly with
11313 multiple occurrences of the same key. [Stephen Scheck
11314 <sscheck infonex.net>, Ben Laurie] PR#1604
11316 *) send_fd_length() did not calculate total_bytes_sent properly in error
11317 cases. [Ben Reser <breser regnow.com>] PR#1366
11319 *) r->connection->user was allocated in the wrong pool causing corruption
11320 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
11322 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
11323 Also removed the auto-generated link to www.apache.org that was the
11324 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
11326 *) Multiple "close" tokens may have been set in the "Connection"
11327 header, not an error, but a waste.
11328 [<Ronald.Tschalaer psi.ch>] PR#1683
11330 *) "basic" and "digest" auth tokens should be tested case-insensitive.
11331 [<Ronald.Tschalaer psi.ch>] PR#1599, PR#1666
11333 *) It appears the "257th byte" bug (see
11334 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
11335 at the 256th byte as well. Fixed. [Dean Gaudet]
11337 *) mod_rewrite would not handle %3f properly in some situations.
11340 *) Apache could generate improperly chunked HTTP/1.1 responses when
11341 the bputc() or rputc() functions were used by modules (such as
11342 mod_include). [Dean Gaudet]
11344 *) #ifdef wrap a few #defines in httpd.h to make life easier on
11345 some ports. [Ralf Engelschall]
11347 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
11349 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
11351 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
11353 Changes with Apache 1.2.5
11355 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
11356 only an issue on systems without a MAXDNAME define or where
11357 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
11359 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
11362 *) Fix core dump in the ftp proxy when reading incorrectly formatted
11363 directory listings. [Marc Slemko]
11365 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
11368 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
11369 is used to read various types of files such as htaccess and
11370 htpasswd files. [Marc Slemko]
11372 *) SECURITY: Ensure that the buffer returned by ht_time is always
11373 properly null terminated. [Marc Slemko]
11375 *) SECURITY: General mod_include cleanup, including fixing several
11376 possible buffer overflows and a possible infinite loop. This cleanup
11377 was done against 1.3 code and then backported to 1.2, the result
11378 is a large difference (due to indentation cleanup in 1.3 code).
11379 Users interested in seeing a smaller set of relevant differences
11380 should consider comparing against src/modules/standard/mod_include.c
11381 from the 1.3b3 release. Non-indentation changes to mod_include
11382 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
11384 *) SECURITY: Numerous changes to mod_imap in a general cleanup
11385 including fixing a possible buffer overflow. This cleanup also
11386 was done with 1.3 code as a basis, see the previous note
11387 about mod_include. [Dean Gaudet]
11389 *) SECURITY: If a htaccess file can not be read due to bad
11390 permissions, deny access to the directory with a HTTP_FORBIDDEN.
11391 The previous behavior was to ignore the htaccess file if it could not
11392 be read. This change may make some setups with unreadable
11393 htaccess files stop working. PR#817 [Marc Slemko]
11395 *) SECURITY: no2slash() was O(n^2) in the length of the input.
11396 Make it O(n). This inefficiency could be used to mount a denial
11397 of service attack against the Apache server. Thanks to
11398 Michal Zalewski <lcamtuf boss.staszic.waw.pl> for reporting
11399 this. [Dean Gaudet]
11401 *) mod_include used uninitialized data for some uses of && and ||.
11402 [Brian Slesinsky <bslesins wired.com>] PR#1139
11404 *) mod_imap should decline all non-GET methods.
11405 [Jay Bloodworth <jay pathways.sde.state.sc.us>]
11407 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
11409 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
11410 r->filename. Since those two are meant to be in sync with each other
11411 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
11413 *) mod_include did not properly handle all possible redirects from sub-
11414 requests. [Ken Coar]
11416 *) Inetd mode (which is buggy) uses timeouts without having setup the
11417 jmpbuffer. [Dean Gaudet] PR#1064
11419 *) Work around problem under Linux where a child will start looping
11420 reporting a select error over and over.
11421 [Rick Franchuk <rickf transpect.net>] PR#1107
11423 Changes with Apache 1.2.4
11425 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
11426 always making requests with the full-URI instead of just the URI path.
11427 [Marc Slemko, Roy Fielding]
11429 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
11430 on this platform. [Marc Slemko]
11432 Changes with Apache 1.2.3
11434 *) The request to a remote proxy was mangled if it was generated as the
11435 result of a ProxyPass directive. URL schemes other than http:// were not
11436 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
11437 PR#812 [Lars Eilebrecht]
11439 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11440 information for case where proxy module is not available. [Marc Slemko]
11442 *) Force proxy to always respond as HTTP/1.0, which it was failing to
11443 do for errors and cached responses. [Roy Fielding]
11445 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
11447 Changes with Apache 1.2.2 [not released]
11449 *) Fixed another long-standing bug in sub_req_lookup_file where it would
11450 happily skip past access checks on subdirectories looked up with relative
11451 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
11454 *) Add lockfile name to error message printed out when
11455 USE_FLOCK_SERIALIZED_ACCEPT is defined.
11458 *) Enhanced the chunking and error handling inside the buffer functions.
11459 [Dean Gaudet, Roy Fielding]
11461 *) When merging the main server's <Directory> and <Location> sections into
11462 a vhost, put the main server's first and the vhost's second. Otherwise
11463 the vhost can't override the main server. [Dean Gaudet] PR#717
11465 *) The <Directory> code would merge and re-merge the same section after
11466 a match was found, possibly causing problems with some modules.
11469 *) Fixed an infinite loop in mod_imap for references above the server root.
11470 [Dean Gaudet] PR#748
11472 *) mod_include cleanup showed that handle_else was being used to handle
11473 endif. It didn't cause problems, but it was cleaned up too.
11476 *) Last official synchronization of mod_rewrite with author version (because
11477 mod_rewrite is now directly developed by the author at the Apache Group):
11478 o added diff between mod_rewrite 3.0.6+ and 3.0.9
11479 minus WIN32/NT stuff, but plus copyright removement.
11481 - workaround for detecting infinite rewriting loops
11482 - fixed setting of env vars when "-" is used as subst string
11483 - fixed forced response code on redirects (PR#777)
11484 - fixed cases where r->args is ""
11485 - kludge to disable locking on pipes under braindead SunOS
11486 - fix for rewritelog in cases where remote hostname is unknown
11487 - fixed totally damaged request_rec walk-back loop
11488 o remove static from local data and add static to global ones.
11489 o replaced ugly proxy finding stuff by simple
11490 find_linked_module("mod_proxy") call.
11491 o added missing negation char on rewritelog()
11492 o fixed a few comment typos
11493 [Ralf S. Engelschall]
11495 *) Anonymous_LogEmail was logging on each subrequest.
11496 [Dean Gaudet] PR#421, PR#868
11498 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11499 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11500 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11501 Additionally mod_browser now triggers during translate_name to workaround
11502 a deficiency in the header_parse phase.

11509 *) Properly treat <files> container like other containers in mod_info.
11510 [Marc Slemko] PR#848
11512 *) The proxy didn't treat the "Host:" keyword of the host header as case-
11513 insensitive. The proxy would corrupt the first line of a response from
11514 an HTTP/0.9 server. [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#813,814
11516 *) mod_include would log some bogus values occasionally.

11519 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
11520 under Solaris 2.x (up through 2.5.1). It has been fixed.
11521 [Dean Gaudet] PR#832
11523 *) API: In HTTP/1.1, whether or not a request message contains a body
11524 is independent of the request method and based solely on the presence
11525 of a Content-Length or Transfer-Encoding. Therefore, our default
11526 handlers need to be prepared to read a body even if they don't know
11527 what to do with it; otherwise, the body would be mistaken for the
11528 next request on a persistent connection. discard_request_body()
11529 has been added to take care of that. [Roy Fielding] PR#378
11531 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
11532 release version number, such that it always increases along the
11533 same lines as our source code branching. [Roy Fielding]
11535 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
11537 Changes with Apache 1.2.1
11539 *) SECURITY: Don't serve file system objects unless they are plain files,
11540 symlinks, or directories. This prevents local users from using pipes
11541 or named sockets to invoke programs for an extremely crude form of

11545 could contain "../" allowing a local user to "publish" any file on
11546 the system. No slashes are allowed now. [Dean Gaudet]
11548 *) SECURITY: It was possible to violate the symlink Options using mod_dir
11549 (headers, readmes, titles), mod_negotiation (type maps), or
11550 mod_cern_meta (meta files). [Dean Gaudet]
11552 *) SECURITY: Apache will refuse to run as "User root" unless
11553 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
11555 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
11556 if it contained a .htaccess disallowing symlinks. This is contrary
11557 to the rule that symlink permissions are tested with the symlink
11558 options of the parent directory. [Dean Gaudet] PR#353
11560 *) CONFIG: The LockFile directive can be used to place the serializing
11561 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
11562 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
11565 *) Request processing now retains state of whether or not the request
11566 body has been read, so that internal redirects and subrequests will
11567 not try to read it twice (and block). [Roy Fielding]
11569 *) Add a placeholder in modules/Makefile to avoid errors with certain
11570 makes. [Marc Slemko]
11572 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

11578 *) Attempt to work around problems with third party libraries that do not
11579 handle high numbered descriptors (examples include bind, and
11580 solaris libc). On all systems apache attempts to keep all permanent
11581 descriptors above 15 (called the low slack line). Solaris users
11582 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
11583 which keeps all non-FILE * descriptors above 255. On all systems
11584 this should make supporting large numbers of vhosts with many open
11585 log files more feasible. If this causes trouble please report it,
11586 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
11587 [Dean Gaudet] various PRs
11589 *) Related to the last entry, network sockets are now opened before
11590 log files are opened. The only known case where this can cause
11591 problems is under Solaris with many virtualhosts and many Listen
11592 directives. But using -DHIGH_SLACK_LINE=256 described above will
11593 work around this problem. [Dean Gaudet]
11595 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
11598 *) Improved unix error response logging. [Marc Slemko]
11600 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
11601 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
11602 when a URL http://... was used in conjunction with a special

11647 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
11648 reading from one buffer and writing to another, at least until it has
11649 a custom timeout handler. [Roy Fielding and Petr Lampa]

11659 *) Virtual hosts with the same ServerName, but on different ports, were

11690 CC=/OPTIM= format in Configuration. Finally, fix compiler
11691 flags if using HP-UX's cc compiler. [Jim Jagielski]
11693 *) Subrequests and internal redirects now inherit the_request from the
11694 original request-line. [Roy Fielding]
11696 *) Test for error conditions before creating output header fields, since
11697 we don't want the error message to include those fields. Likewise,
11698 reset the content_language(s) and content_encoding of the response
11699 before generating or redirecting to an error message, since the new
11700 message will have its own Content-* definitions. [Dean Gaudet]
11702 *) Restored the semantics of headers_out (headers sent only with 200..299
11703 and 304 responses) and err_headers_out (headers sent with all responses).
11704 Avoid the overhead of copying tables if err_headers_out is empty
11705 (the usual case). [Roy Fielding]
11707 *) Fixed a couple places where a check for the default Content-Type was
11708 not properly checking both the value configured by the DefaultType

11717 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
11720 *) The method for determining PATH_INFO has been restored to the pre-1.2b
11721 (and NCSA httpd) definition wherein it was the extra path info beyond
11722 the CGI script filename. The environment variable FILEPATH_INFO has
11723 been removed, and instead we supply the original REQUEST_URI to any
11724 script that wants to be Apache-specific and needs the real URI path.
11725 This solves a problem with existing scripts that use extra path info
11726 in the ScriptAlias directive to pass options to the CGI script.
11729 *) The _default_ change in 1.2b10 will change the behaviour on configs
11730 that use multiple Listen statements for listening on multiple ports.
11731 But that change is necessary to make _default_ consistent with other
11732 forms of <VirtualHost>. It requires such configs to be modified
11733 to use <VirtualHost _default_:*>. The documentation has been
11734 updated. [Dean Gaudet] PR#530

11774 [Roy Fielding and Sameer Parekh]
11776 *) Fix graceful restart. Eliminate many signal-related race
11777 conditions in both forms of restart, and in SIGTERM. See
11778 htdocs/manual/stopping.html for details on stopping and
11779 restarting the parent. [Dean Gaudet]
11781 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
11782 memory allocator to avoid a behaviour that required extra blocks to
11783 be allocated. [Dean Gaudet]
11785 *) Allow suexec to access files relative to current directory but not
11786 above. (Excluding leading / or any .. directory.) [Ken Coar]
11789 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
11790 PR#367, 368, 354, 453
11792 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
11793 while obtaining the /~user and save the username in a separate data
11794 area so that it won't be overwritten by the call to getgrgid(), and
11795 fix some misuse of the pool string allocation functions. Also fixes
11796 a general problem with parsing URL query info into args for CGI scripts.
11797 [Roy Fielding] PR#339, 367, 354, 453
11799 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
11801 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
11803 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
11804 AuthDBAuthoritative. [Marc Slemko] PR#420
11806 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
11808 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
11809 object that can't be PUT, or FOOBAR for some method FOOBAR that
11810 apache doesn't know about at all). Log 404s that occur in mod_include.
11811 [Paul Sutton, John Van Essen]
11813 *) If a soft timeout (or lingerout) occurs while trying to flush a
11814 buffer or write inside buff.c or fread'ing from a CGI's output,
11815 then the timeout would be ignored. [Roy Fielding] PR#373
11817 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
11818 parsing of headers. If the terminating empty-line CRLF occurs starting
11819 at the 256th or 257th byte of output, then Navigator will think a normal
11820 image is invalid. We are guessing that this is because their initial
11821 read of a new request uses a 256 byte buffer. We check the bytes written
11822 so far and, if we are about to tickle the bug, we instead insert a
11823 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
11825 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
11826 of an external redirection. [Roy Fielding and Paul Sutton]
11828 *) Configure would create a broken Makefile if the configuration file
11829 contained a commented-out Rule. [Roy Fielding]
11831 *) Promote per_dir_config and subprocess_env from the subrequest to the
11832 main request in mod_negotiation. In particular this fixes a bug
11833 where <Files> sections wouldn't properly apply to negotiated content.
11836 *) Fix a potential deadlock in mod_cgi script_err handling.
11837 [Ralf S. Engelschall]
11839 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
11840 [Mitchell Blank Jr]
11842 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
11843 .htaccess files because the RewriteBase was not replaced correctly.
11844 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
11845 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
11847 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
11848 1.x the settings are those of pre-1.2b8. For 2.x we include
11849 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
11850 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
11851 [Dean Gaudet] PR#336, PR#340
11853 *) Redirect did not preserve ?query_strings when present in the client's
11854 request. [Dean Gaudet]
11856 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
11858 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
11860 *) Add UnixWare compile/install instructions. [Chuck Murcko]
11862 *) Add mod_example (illustration of API techniques). [Ken Coar]
11864 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
11866 *) Improve handling of directories when filenames have spaces in them.
11869 *) For hosts with multiple IP addresses, try all additional addresses if
11870 necessary to get a connect. Fail only if hostent address list is
11871 exhausted. [Chuck Murcko]
11873 *) More signed/unsigned port fixes. [Dean Gaudet]
11875 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
11878 Changes with Apache 1.2b8
11880 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
11881 to it. [Marc Slemko]
11883 *) The addition of <Location> and <File> directives made the
11884 sub_req_lookup_simple() function bogus, so we now handle
11885 the special cases directly. [Dean Gaudet]
11887 *) We now try to log where the server is dumping core when a fatal
11888 signal is received. [Ken Coar]
11890 *) Improved lingering_close by adding a special timeout, removing the
11891 spurious log messages, removing the nonblocking settings (they
11892 are not needed with the better timeout), and adding commentary
11893 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
11894 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
11896 *) Send error messages about setsockopt failures to the server error
11897 log instead of stderr. [Roy Fielding]
11899 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
11901 *) Stopgap solution for CGI 3-second delay with server-side includes: if
11902 processing a subrequest, allocate memory from r->main->pool instead
11903 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
11904 in the middle of an SSI request. [Dean Gaudet] PR #122
11906 *) Fixed status of response when POST is received for a nonexistent URL
11907 (was sending 405, now 404) and when any method is sent with a
11908 full-URI that doesn't match the server and the server is not acting
11909 as a proxy (was sending 501, now 403). [Roy Fielding]
11911 *) Host port changed to unsigned short. [Ken Coar] PR #276
11913 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
11915 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
11917 *) Report extra info from errno with many errors that cause httpd to exit.
11918 spawn_child, popenf, and pclosef now have valid errno returns in the
11919 event of an error. Correct problems where errno was stomped on
11920 before being reported. [Dean Gaudet]
11922 *) In the proxy, if the cache filesystem was full, garbage_coll() was
11923 never called, and thus the filesystem would remain full indefinitely.
11924 We now also remove incomplete cache files left if the origin server
11925 didn't send a Content-Length header and either the client has aborted
11926 transfer or bwrite() to client has failed. [Petr Lampa]
11928 *) Fixed the handling of module and script-added header fields.
11929 Improved the interface for sending header fields and reduced
11930 the duplication of code between sending okay responses and errors.
11931 We now always send both headers_out and err_headers_out, and
11932 ensure that the server-reserved fields are not being overridden,
11933 while not overriding those that are not reserved. [Roy Fielding]
11935 *) Moved transparent content negotiation fields to err_headers_out
11936 to reflect above changes. [Petr Lampa]
11938 *) Fixed the determination of whether or not we should make the
11939 connection persistent for all of the cases where some other part
11940 of the server has already indicated that we should not. Also
11941 improved the ordering of the test so that chunked encoding will
11942 be set whenever it is desired instead of only when KeepAlive
11943 is enabled. Added persistent connection capability for most error
11944 responses (those that do not indicate a bad input stream) when
11945 accessed by an HTTP/1.1 client. [Roy Fielding]
11947 *) Added missing timeouts for sending header fields, error responses,
11948 and the last chunk of chunked encoding, each of which could have
11949 resulted in a process being stuck in write forever. Using soft_timeout
11950 requires that the sender check for an aborted connection rather than
11951 continuing after an EINTR. Timeouts that used to be initiated before
11952 send_http_header (and never killed) are now initiated only within or
11953 around the routines that actually do the sending, and not allowed to
11954 propagate above the caller. [Roy Fielding]
11956 *) mod_auth_anon required an @ or a . in the email address, not both.
11959 *) per_dir_defaults weren't set correctly until directory_walk for
11960 name-based vhosts. This fixes an obscure bug with the wrong config
11961 info being used for vhosts that share the same ip as the server.
11964 *) Improved generation of modules/Makefile to be more generic for
11965 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
11967 *) Generate makefile dependency for Configuration based on the actual
11968 name given when running the Configure process. [Dean Gaudet]
11970 *) Fixed problem with vhost error log not being set prior to
11971 initializing virtual hosts. [Dean Gaudet]
11973 *) Fixed infinite loop when a trailing slash is included after a type map
11974 file URL (extra path info). [Petr Lampa]
11976 *) Fixed server status updating of per-connection counters. [Roy Fielding]
11978 *) Add documentation for DNS issues (reliability and security), and try
11979 to explain the virtual host matching process. [Dean Gaudet]
11981 *) Try to continue gracefully by disabling the vhost if a DNS lookup
11982 fails while parsing the configuration file. [Dean Gaudet]
11984 *) Improved calls to setsockopt. [Roy Fielding]
11986 *) Negotiation changes: Don't output empty content-type in variant list;
11987 Output charset in variant list; Return sooner from handle_multi() if
11988 no variants found; Add handling of '*' wildcard in Accept-Charset.
11989 [Petr Lampa and Paul Sutton]
11991 *) Fixed overlaying of request/sub-request notes and headers in
11992 mod_negotiation. [Dean Gaudet]
11994 *) If two variants' charset quality are equal and one is the default
11995 charset (iso-8859-1), then prefer the variant that was specifically
11996 listed in Accept-Charset instead of the default. [Petr Lampa]
11998 *) Memory allocation problem in push_array() -- it would corrupt memory
11999 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
12001 *) invoke_handler() doesn't handle mime arguments in content-type
12002 [Petr Lampa] PR#160
12004 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
12007 *) Fixed problem with ErrorDocument not working for virtual hosts
12008 due to one of the performance changes in 1.2b7. [Dean Gaudet]
12010 *) Log an error message if we get a request header that is too long,
12011 since it may indicate a buffer overflow attack. [Marc Slemko]
12013 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
12014 not reject URLs without a double-slash, as per RFC2068 section 3.2.
12015 [Ken Coar] PR #146, #187
12017 *) Added table entry placeholder for new header_parser callback
12018 in all of the distributed modules. [Ken Coar] PR #191
12020 *) Allow for cgi files without the .EXE extension on them under OS/2.
12021 [Garey Smiley] PR #59
12023 *) Fixed error message when resource is not found and URL contains
12024 path info. [Petr Lampa and Dean Gaudet] PR #40
12026 *) Fixed user and server confusion over what should be a virtual host
12027 and what is the main server, resulting in access to something
12028 other than the name defined in the virtualhost directive (but
12029 with the same IP address) failing. [Dean Gaudet]
12031 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
12032 AIX; improves the redirection stuff to enable the users to generally
12033 redirect to http, https, gopher and ftp; added TIME variable for
12034 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
12035 special patterns >STRING, <STRING and =STRING to RewriteCond, which
12036 can be used in conjunction with %{TIME} or other variables to create
12037 time-dependent rewriting rules. [Ralf S. Engelschall]
12039 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
12040 Module authors may need to adjust their code for proper cleanup to take
12041 place (that is, call note_cleanups_for_fd()). This change fixes problems
12042 with file descriptors being erroneously closed when the proxy module was
12043 in use. [Ben Laurie]
12045 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
12046 initgroups() to hose the group information needed for later
12047 comparisons. [Randy Terbush]
12049 *) Remove unnecessary call to va_end() in create_argv() which
12050 caused a SEGV on some systems.
12052 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
12055 *) Clear memory allocated for listeners. [Randy Terbush]
12057 *) Improved handling of IP address as a virtualhost address and
12058 introduced "_default_" as a synonym for the default vhost config.
12059 [Dean Gaudet] PR #212
12061 Changes with Apache 1.2b7
12063 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
12065 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
12067 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
12068 - replace protocol response numbers with symbols
12069 - save variant-list into main request notes
12070 - free allocated memory from subrequests
12071 - merge notes, headers_out and err_headers_out
12073 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
12074 "HTTP/#.# ###*" to be more lenient about what we accept.
12077 *) more proxy FTP bug fixes:
12078 - Changed send_dir() to remove user/passwd from displayed URL.
12079 - Changed login error messages to be more descriptive.
12080 - remove setting of SO_DEBUG socket option
12081 - Make ftp_getrc() more lenient about multiline responses,
12082 specifically, 230 responses which don't have continuation 230-
12083 on each line). These seem to be all NT FTP servers, and while
12084 perhaps questionable, they appear to be legal by RFC 959.
12085 - Add missing kill_timeout() after transfer to user completes.
12088 *) Fixed problem where a busy server could hang when restarting
12089 after being sent a SIGHUP due to child processes not exiting.
12092 *) Modify mod_include escaping so a '\' only signifies an escaped
12093 character if the next character is one that needs
12094 escaping. [Ben Laurie]
12096 *) Eliminated possible infinite loop in mod_imap when relative URLs are
12097 used with a 'base' directive that does not have a '/' in it.
12098 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
12100 *) Reduced the default timeout from 1200 seconds to 300, and the
12101 one in the sample configfile from 400 to 300. [Marc Slemko]
12103 *) Stop vbprintf from crashing if given a NULL string pointer;
12104 print (null) instead. [Ken Coar]
12106 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
12107 [Marc Slemko and Roy Fielding]
12109 *) Fixed problem with mod_cgi-generated internal redirects trying to
12110 read the request message-body twice. [Archie Cobbs and Roy Fielding]
12112 *) Reduced timeout on lingering close, removed possibility of a blocked
12113 read causing the child to hang, and stopped logging of errors if
12114 the socket is not connected (reset by client). [Roy Fielding]
12116 *) Rearranged main child loop to remove duplication of code in
12117 select/accept and keep-alive requests, fixed several bugs regarding
12118 checking scoreboard_image for exit indication and failure to
12119 account for all success conditions and trap all error conditions,
12120 prevented multiple flushes before closing the socket; close the entire
12121 socket buffer instead of just one descriptor, prevent logging of
12122 EPROTO and ECONNABORTED on platforms where supported, and generally
12123 improved readability. [Roy Fielding]
12125 *) Extensive performance improvements. Cleaned up inefficient use of
12126 auto initializers, multiple is_matchexp calls on a static string,
12127 and excessive merging of response_code_strings. [Dean Gaudet]
12129 *) Added double-buffering to mod_include to improve performance on
12130 server-side includes. [Marc Slemko]
12132 *) Several fixes for suexec wrapper. [Randy Terbush]
12133 - Make wrapper work for files on NFS filesystem.
12134 - Fix portability problem of MAXPATHLEN.
12135 - Fix array overrun problem in clean_env().
12136 - Fix allocation of PATH environment variable
12138 *) Removed extraneous blank line is description of mod_status chars.
12141 *) Logging of errors from the call_exec routine simply went nowhere,
12142 since the logfile fd has been closed, so now we send them to stderr.
12143 [Harald T. Alvestrand]
12145 *) Fixed core dump when DocumentRoot is a CGI.
12146 [Ben Laurie, reported by <geddis tesserae.com>]
12148 *) Fixed potential file descriptor leak in mod_asis; updated it and
12149 http_core to use pfopen/pfclose instead of fopen/fclose.
12150 [Randy Terbush and Roy Fielding]
12152 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
12153 as the DEC Alpha which is 64-bit but uses 32-bit ints.
12154 [Dean Gaudet and Ken Coar]
12156 *) Return a 302 response code to the client when sending a redirect
12157 due to a missing trailing '/' on a directory instead of a 301; now
12158 it is cacheable. [Markus Gyger]
12160 *) Fix condition where, if a bad directive occurs in .htaccess, and
12161 sub_request() goes first to this directory, then log_reason() will
12162 SIGSEGV because it doesn't have initialized r->per_dir_config.
12163 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
12165 *) Fix handling of lang_index in is_variant_better(). This was
12166 causing problems which resulted in the server sending the
12167 wrong language document in some cases. [Petr Lampa]
12169 *) Remove free() from clean_env() in suexec wrapper. This was nuking
12170 the clean environment on some systems.
12172 *) Tweak byteserving code (e.g. serving PDF files) to work around
12173 bugs in Netscape Navigator and Microsoft Internet Explorer.
12174 Emit Content-Length header when sending multipart/byteranges.
12177 *) Port to HI-UX/WE2. [Nick Maclaren]
12179 *) Port to HP MPE operating system for HP 3000 machines
12180 [Mark Bixby <markb cccd.edu>]
12182 *) Fixed bug which caused a segmentation fault if only one argument
12183 given to RLimit* directives. [Ed Korthof]
12185 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
12187 *) Improved buffered output to the client by delaying the flush decision
12188 until the BUFF code is actually about to read the next request.
12189 This fixes a problem introduced in 1.2b5 with clients that send
12190 an extra CRLF after a POST request. Also improved chunked output
12191 performance by combining writes using writev() and removing as
12192 many bflush() calls as possible. NOTE: Platforms without writev()
12193 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
12194 or Configure, unless we have already done so. [Dean Gaudet]
12196 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
12198 *) Fixed mod_info output corruption bug introduced by buffer overflow
12199 fixes. [Dean Gaudet]
12201 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
12202 for the special case of a 304 response. [Paul Sutton]
12204 *) Improved handling of TRACE method by bypassing normal method handling
12205 and header parsing routines; fixed Allow response to always allow TRACE.
12208 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
12210 *) Cleaned-up some of the generated HTML. [Ken Coar]
12212 Changes with Apache 1.2b6
12214 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
12216 *) Fix typo introduced in fix for potential infinite loop around
12217 accept() in child_main(). This change caused the rev to 1.2b6.
12218 1.2b5 was never a public beta.
12220 Changes with Apache 1.2b5
12222 *) Change KeepAlive semantics (On|Off instead of a number), add
12223 MaxKeepAliveRequests directive. [Alexei Kosut]
12225 *) Various NeXT compilation patches, as well as a change in
12226 regex/regcomp.c since that file also used a NEXT define.
12229 *) Allow * to terminate the end of a directory match in mod_dir.
12230 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
12232 *) Don't call can_exec() if suexec_enabled. Calling this requires
12233 scripts executed by the suexec wrapper to be world executable, which
12234 defeats one of the advantages of running the wrapper. [Randy Terbush]
12236 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
12239 *) Migration from sprintf() to snprintf() to avoid buffer
12240 overflows. [Marc Slemko]
12242 *) Provide portable snprintf() implementation (ap_snprintf)
12243 as well as *cvt family. [Jim Jagielski]
12245 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
12248 *) Remove mod_fastcgi.c from the distribution. This module appears
12249 to be maintained more through the Open Market channels and should
12250 continue to be easily available at http://www.fastcgi.com/
12252 *) Fixed bug in modules/Makefile that wouldn't allow building in more
12253 than one subdirectory (or cleaning, either). [Jeremy Laidman]
12255 *) mod_info assumed that the config files were relative to ServerRoot.
12258 *) CGI scripts called as an error document resulting from failed
12259 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
12261 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
12264 *) Properly check errno to prevent display of a directory index
12265 when server receives a long enough URL to confuse stat().
12268 *) Several security enhancements to suexec wrapper. It is _highly_
12269 recommended that previously installed versions of the wrapper
12270 be replaced with this version. [Randy Terbush, Jason Dour]
12272 - ~user execution now properly restricted to ~user's home
12273 directory and below.
12274 - execution restricted to UID/GID > 100
12275 - restrict passed environment to known variables
12276 - call setgid() before initgroups() (portability fix)
12277 - remove use of setenv() (portability fix)
12279 *) Add HTTP/1.0 response forcing. [Ben Laurie]
12281 *) Add access control via environment variables. [Ben Laurie]
12283 *) Add rflush() function. [Alexei Kosut]
12285 *) remove duplicate pcalloc() call in new_connection().
12287 *) Fix incorrect comparison which could allow number of children =
12288 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
12289 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
12291 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
12292 AIX PS/2, CONVEXOS. [Jim Jagielski]
12294 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
12295 It's more portable. [Martin Kraemer]
12297 *) Replace references to make in Makefile.tmpl with $(MAKE).
12300 *) Add ProxyBlock directive w/IP address caching. Add IP address
12301 caching to NoCache directive as well. ProxyBlock works with all
12302 handlers; NoCache now also works with FTP for anonymous logins.
12303 Still more code cleanup. [Chuck Murcko]
12305 *) Add "header parse" API hook [Ben Laurie]
12307 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
12309 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
12311 *) Correctly allow access and auth directives in <Files> sections in
12312 server config files. [Alexei Kosut]
12314 *) Fix bug with ServerPath that could cause certain files to be not
12315 found by the server. [Alexei Kosut]
12317 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
12318 double-quote from text and so that it properly checks for unsupported
12319 status codes using the new index_of_response interface. [Roy Fielding]
12321 *) Multiple fixes to the lingering_close code in order to avoid being
12322 interrupted by a stray timeout, to avoid lingering on a connection
12323 that has already been aborted or never really existed, to ensure that
12324 we stop lingering as soon as any error condition is received, and to
12325 prevent being stuck indefinitely if the read blocks. Also improves
12326 reporting of error conditions. [Marc Slemko and Roy Fielding]
12328 *) Fixed initialization of parameter structure for sigaction.
12329 [<mgyger itr.ch>, Adrian Filipi-Martin]
12331 *) Fixed reinitializing the parameters before each call to accept and
12332 select, and removed potential for infinite loop in accept.
12333 [Roy Fielding, after useful PR from <adrian virginia.edu>]
12335 *) Fixed condition where, if a child fails to fork, the scoreboard would
12336 continue to say SERVER_STARTING forever. Eventually, the main process
12337 would refuse to start new children because count_idle_servers() will
12338 count those SERVER_STARTING entries and will always report that there
12339 are enough idle servers. [Phillip Vandry]
12341 *) Fixed bug in bcwrite regarding failure to account for partial writes.
12342 Avoided calling bflush() when the client is pipelining requests.
12343 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
12345 *) Added description of "." mode in server-status [Jim Jagielski]
12347 Changes with Apache 1.2b4
12349 *) Fix possible race condition in accept_mutex_init() that
12350 could leave a small security hole open allowing files to be
12351 overwritten in cases where the server UID has write permissions.
12354 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
12356 *) Fix portablity problem in util_script where ARG_MAX may not be
12357 defined for some systems.
12359 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
12362 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
12363 style magic #! token for better script portability. [Garey Smiley]
12365 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
12366 execution for ~userdir CGI. [Jason Dour]
12368 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
12370 *) Fix month off by one in suexec wrapper logging.
12372 Changes with Apache 1.2b3:
12374 *) Fix error in mod_cgi which could cause resources not to be properly
12375 freed, or worse. [Dean Gaudet]
12377 *) Fix find_string() NULL pointer dereference. [Howard Fear]
12379 *) Add set_flag_slot() at the request of Dirk and others.
12382 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
12384 *) Add changes to improve the error message given for invalid
12385 ServerName parameters. [Dirk vanGulik]
12387 *) Add "Authoritative" directive for Auth modules that don't
12388 currently have it. This gives admin control to assign authoritative
12389 control to an authentication scheme and allow "fall through" for
12390 those authentication modules that aren't "Authoritative" thereby
12391 allowing multiple authentication mechanisms to be chained.
12394 *) Remove requirement for ResourceConfig/AccessConfig if not using
12395 the three config file layout. [Randy Terbush]
12397 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
12399 *) Changes to suexec wrapper to fix the following problems:
12400 1. symlinked homedirs will kill ~userdirs.
12401 2. initgroups() on Linux 2.0.x clobbers gr->grid.
12402 3. CGI command lines paramters problems
12403 4. pw-pwdir for "docroot check" still the httpd user's pw record.
12404 [Randy Terbush, Jason Dour]
12406 *) Change create_argv() to accept variable arguments. This fixes
12407 a problem where arguments were not getting passed to the CGI via
12408 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
12410 *) Collapse multiple slashes in path URLs to properly apply
12411 handlers defined by <Location>. [Alexei Kosut]
12413 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
12415 *) Improve the accuracy of request duration timings by setting
12416 r->request_time in read_request_line() instead of read_request().
12419 *) Reset timeout while reading via get_client_block() in mod_cgi.c
12420 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
12422 *) Add the ability to pass different Makefile.tmpl files to Configure
12423 using the -make flag. [Rob Hartill]
12425 *) Fix coredump triggered when sending a SIGHUP to the server caused
12426 by an assertion failure, in turn caused by an uninitialised field in a
12430 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
12431 PATH_INFO from previous versions of Apache (in certain situations,
12432 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
12433 [later removed in 1.2b11]
12435 *) Add rwrite() function to API to allow for sending strings of
12436 arbitrary length. [Doug MacEachern]
12438 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
12440 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
12441 NeXT. [Jim Jagielski]
12443 *) Removed recent modification to promote the status code on internal
12444 redirects, since the correct fix was to change the default log format
12445 in mod_log_config so that it outputs the original status. [Rob Hartill]
12447 Changes with Apache 1.2b2:
12449 *) Update set_signals() to use sigaction() for setting handlers.
12450 This appears to fix a re-entrant problem in the seg_fault()
12451 bus_error() handlers. [Randy Terbush]
12453 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
12455 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
12457 *) proxy_http.c bugfixes: [Chuck Murcko]
12458 1) fixes possible NULL pointer reference w/NoCache
12459 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
12460 host would cache nothing if it was in the local domain,
12461 and the local domain was in the NoCache list)
12462 3) Adds Host: header when not available
12463 4) Some code cleanup and clarification
12465 *) mod_include.c bugfixes:
12466 1) Fixed an ommission that caused include variables to not
12467 be parsed in config errmsg directives [Howard Fear]
12468 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
12469 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
12470 4) Allow backslash-escaping to all quoted text
12471 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
12472 5) Pass variable to command line if not set in XSSI's env
12475 *) Fix infinite loop when processing Content-language lines in
12476 type-map files. [Alexei Kosut]
12478 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
12480 *) Fixed problem in set_[user|group] that prevented CGI execution
12481 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
12483 *) Added PORTING information file. [Jim Jagielski]
12485 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
12487 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
12489 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
12490 USE_FCNTL_SERIALIZED_ACCEPT was intended.
12492 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
12493 which caused problems of systems where socket s_addr is >32bits.
12495 *) Added comment to explain (r->chunked = 1) side-effect in
12496 http_protocol.c [Roy Fielding]
12498 *) Replaced use of index() in mod_expires.c with more appropriate
12499 and portable isdigit() test. [Ben Laurie]
12501 *) Updated Configure for ...
12502 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
12503 *-dg-dgux* (bad pattern match)
12504 QNX (DEF_WANTHSREGEX=yes)
12505 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
12507 *-unixware211 (new)
12508 and added some user diagnostic info. [Ben Laurie]
12510 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
12511 for better portability. [Jim Jagielski]
12513 *) Updated helpers/GuessOS for ...
12514 SCO 5 (recognize minor releases)
12515 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
12516 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
12517 IRIX64 (-sgi-irix64)
12518 ULTRIX (-unknown-ultrix)
12519 SINIX (-whatever-sysv4)
12520 NCR Unix (-ncr-sysv4)
12521 and fixed something in helpers/PrintPath [Ben Laurie]
12523 Changes with Apache 1.2b1
12525 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
12527 Changes with Apache 1.1.1
12529 *) Fixed bug where Cookie module would make two entries in the
12530 logfile for each access [Mark Cox]
12532 *) Fixed bug where Redirect in .htaccess files would cause memory
12533 leak. [Nathan Neulinger]
12535 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
12537 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
12539 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
12541 Changes with Apache 1.1.0
12543 *) Bring NeXT support up to date. [Takaaki Matsumoto]
12545 *) Bring QNX support up to date. [Ben Laurie]
12547 *) Make virtual hosts default to main server keepalive parameters.
12548 [Alexei Kosut, Ben Laurie]
12550 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
12552 *) Fix missing address family for connect, also remove unreachable statement
12553 in mod_proxy. [Ben Laurie]
12555 *) mod_env now turned on by default in Configuration.tmpl.
12557 *) Bugs which were fixed:
12558 a) yet more mod_proxy bugs [Ben Laurie]
12559 b) CGI works again with inetd [Alexei Kosut]
12560 c) Leading colons were stripped from passwords [<osm interguide.com>]
12561 d) Another fix to multi-method Limit problem [<jk tools.de>]
12563 Changes with Apache 1.1b4
12565 *) r->bytes_sent variable restored. [Robert Thau]
12567 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
12569 *) More possibly unsecure programs removed from the support directory.
12571 *) More mod_auth_msql authentication improvements.
12573 *) VirtualHosts based on Host: headers no longer conflict with the
12576 *) OS/2 compatibility enhancements. [Gary Smiley]
12578 *) POST now allowed to directory index CGI scripts.
12580 *) Actions now work with files of the default type.
12582 *) Bugs which were fixed:
12583 a) more mod_proxy bugs
12584 b) early termination of inetd requests
12585 c) compile warnings on several systems
12586 d) problems when scripts stop reading output early
12588 Changes with Apache 1.1b3
12590 *) Much of cgi-bin and all of cgi-src has been removed, due to
12591 various security holes found and that we could no longer support
12594 *) The "Set-Cookie" header is now special-cased to not merge multiple
12595 instances, since certain popular browsers can not handle multiple
12596 Set-Cookie instructions in a single header. [Paul Sutton]
12598 *) rprintf() added to buffer code, occurrences of sprintf removed.
12601 *) CONNECT method for proxy module, which means tunneling SSL should work.
12602 (No crypto needed) Also a NoCache config directive.
12604 *) Several API additions: pstrndup(), table_unset() and get_token()
12605 functions now available to modules.
12607 *) mod_imap fixups, in particular Location: headers are now complete
12610 *) New "info" module which reports on installed module set through a
12611 special URL, a la mod_status.
12613 *) "ServerPath" directive added - allows for graceful transition
12614 for Host:-header-based virtual hosts.
12616 *) Anonymous authentication module improvements.
12618 *) MSQL authentication module improvements.
12620 *) Status module design improved - output now table-based. [Ben Laurie]
12622 *) htdigest utility included for use with digest authentication
12625 *) mod_negotiation: Accept values with wildcards to be treated with
12626 less priority than those without wildcards at the same quality
12627 value. [Alexei Kosut]
12629 *) Bugs which were fixed:
12630 a) numerous mod_proxy bugs
12631 b) CGI early-termination bug [Ben Laurie]
12632 c) Keepalives not working with virtual hosts
12633 d) RefererIgnore problems
12634 e) closing fd's twice in mod_include (causing core dumps on
12635 Linux and elsewhere).
12637 Changes with Apache 1.1b2
12640 a) core dumps in mod_digest
12641 b) truncated hostnames/ip address in the logs
12642 c) relative URL's in mod_imap map files
12644 Changes with Apache 1.1b1
12646 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12648 Changes with Apache 1.0.3
12650 *) Internal redirects which occur in mod_dir.c now preserve the
12651 query portion of a request (the bit after the question mark).
12654 *) Escape active characters '<', '>' and '&' in html output in
12655 directory listings, error messages and redirection links.
12658 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12660 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12663 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12665 *) Reset timeout timer after each successful fwrite() to the network.
12666 This patch adds a reset_timeout() procedure that is called by
12667 send_fd() to reset the timeout ever time data is written to the net.
12670 *) timeout() signal handler now checks for SIGPIPE and reports
12671 lost connections in a more user friendly way. [Rob Hartill]
12673 *) Location of the "scoreboard" file which used to live in /tmp is
12674 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12675 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12677 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12679 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12680 which caused a SEGV with cookies enabled
12682 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12685 *) Log the UNIX textual error returned by some system calls, in
12686 particular errors from accept() [David Robinson]
12688 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12690 Changes with Apache 1.0.2
12692 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12693 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12695 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12698 *) past changes to http_config.c to only use the
12699 setrlimit function on systems defining RLIMIT_NOFILE
12700 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12701 for SUNOS and prototypes the needed functions.
12703 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12706 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12708 *) Merge multiple headers from CGI scripts instead of taking last
12709 one. [David Robinson]
12711 *) Add support for SCO 5. [Ben Laurie]
12713 Changes with Apache 1.0.1
12715 *) Silence mod_log_referer and mod_log_agent if not configured
12718 *) Recursive includes can occur if the client supplies PATH_INFO data
12719 and the server provider uses relative links; as file.html
12720 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
12722 *) The replacement for initgroups() did not call {set,end}grent(). This
12723 had two implications: if anything else used getgrent(), then
12724 initgroups() would fail, and it was consuming a file descriptor.
12727 *) On heavily loaded servers it was possible for the scoreboard to get
12728 out of sync with reality, as a result of a race condition.
12729 The observed symptoms are far more Apaches running than should
12730 be, and heavy system loads, generally followed by catastrophic
12731 system failure. [Ben Laurie]
12733 *) Fix typo in license. [David Robinson]
12735 Changes with Apache 1.0.0 23 Nov 1995
12737 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
12739 Changes with Apache 0.8.16 05 Nov 1995
12741 *) New man page for 'httpd' added to support directory [David Robinson]
12743 *) .htgroup files can have more than one line giving members for a
12744 given group (each must have the group name in front), for NCSA
12745 back-compatibility [Robert Thau]
12747 *) Mutual exclusion around accept() is on by default for SVR4 systems
12748 generally, since they generally can't handle multiple processes in
12749 accept() on the same socket. This should cure flaky behavior on
12750 a lot of those systems. [David Robinson]
12752 *) AddType, AddEncoding, and AddLanguage directives take multiple
12753 extensions on a single command line [David Robinson]
12755 *) UserDir can be disabled for a given virtual host by saying
12756 "UserDir disabled" in the <VirtualHost> section --- it was a bug
12757 that this didn't work. [David Robinson]
12759 *) Compiles on QNX [Ben Laurie]
12761 *) Corrected parsing of ctime time format [David Robinson]
12763 *) httpd does a perror() before exiting if it can't log its pid
12764 to the PidFile, to make diagnosing the error a bit easier.
12767 *) <!--#include file="..."--> can no longer include files in the
12768 parent directory, for NCSA back-compatibility. [David Robinson]
12770 *) '~' is *not* escaped in URIs generated for directory listings
12773 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
12775 *) Fixed bug involving handling URIs with escaped %-characters
12776 in redirects [David Robinson]
12778 Changes with Apache 0.8.15 14 Oct 1995
12780 *) Switched to new, simpler license
12782 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
12784 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
12786 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
12788 *) Correctly handles internal redirects to files with names containing '%'
12791 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
12793 *) Use geteuid() rather than getuid() to see if we have root privilege,
12794 so that server correctly resets privilege if run setuid root. [Andrew
12797 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
12800 *) Fix relative URLs in imagemap files [Randy Terbush]
12802 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
12805 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
12806 entries all name the same one. [David Robinson]
12808 *) Fix directory listings with filenames containing unusual characters
12811 *) Better URI-escaping for generated URIs in directories with filenames
12812 containing unusual characters [Ben Laurie]
12814 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
12816 *) Unblock alarms on error return from spawn_child() [David Robinson]
12818 *) Sample Config files have extra note for SCO users [Ben Laurie]
12820 *) Configuration has note for HP-UX users [Rob Hartill]
12822 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
12824 *) Nuked bogus #define in httpd.h [David Robinson]
12826 *) Better test for whether a system has setrlimit() [David Robinson]
12828 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
12830 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
12833 Changes with Apache 0.8.14 19 Sep 1995
12835 *) Compiles on SCO ODT 3.0 [Ben Laurie]
12837 *) AddDescription works (better) [Ben Laurie]
12839 *) Leaves an intelligible error diagnostic when it can't set group
12840 privileges on standalone startup [Andrew Wilson]
12842 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
12843 that machine, which claims to be BSD but does not support RLIMIT.
12846 *) gcc -Wall no longer complains about an unused variable when util.c
12847 is compiled with -DMINIMAL_DNS [Andrew Wilson]
12849 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
12851 Changes with Apache 0.8.13 07 Sep 1995
12853 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
12855 *) Have built-in imagemap code recognize & honor Point directive [James
12858 *) Generate cleaner directory listings in directories with a mix of
12859 long and short filenames [Rob Hartill]
12861 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
12863 *) Properly default ServerName for virtual servers [Robert Thau]
12865 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
12866 Paul Richards and a cast of thousands...]
12868 *) On self-identified BSD systems (we don't try to guess any more),
12869 allocate a few extra file descriptors per virtual host with setrlimit,
12870 if we can, to avoid running out. [Randy Terbush]
12872 *) Write 22-character lock file name into buffer with enough space
12873 on startup [Konstantin Olchanski]
12875 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
12878 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
12880 *) Suppress -Wall warning by initializing variable in negotiation code
12881 [Tobias Weingartner]
12883 Changes with Apache 0.8.12 31 Aug 1995
12885 *) Doesn't pause three seconds after including a CGI script which is
12886 too slow to die off (this is done by not even trying to kill off
12887 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
12888 after the entire document has been processed). [Robert Thau]
12890 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
12892 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
12894 *) Allows .htaccess files to override <Directory> sections naming the
12895 same directory [David Robinson]
12897 *) Removed an efficiency hack in sub_req_lookup_uri which was
12898 causing certain extremely marginal cases (e.g., ScriptAlias of a
12899 *particular* index.html file) to fail. [David Robinson]
12901 *) Doesn't log an error when the requested URI requires
12902 authentication, but no auth header line was supplied by the
12903 client; this is a normal condition (the client doesn't no auth is
12904 needed here yet). [Robert Thau]
12906 *) Behaves more sanely when the name server loses its mind [Sean Welch]
12908 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
12910 *) RFC931 code no longer passes out name of prior clients on current
12911 requests if the current request came from a server that doesn't
12912 do RFC931. [David Robinson]
12914 *) Configuration script accepts "Module" lines with trailing whitespace.
12917 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
12919 *) Cleaned up comments in mod_cgi.c [Robert Thau]
12921 Changes with Apache 0.8.11 24 Aug 1995
12923 *) Wildcard <Directory> specifications work. [Robert Thau]
12925 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
12927 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
12928 the file being requested itself, in addition to the directories leading
12929 up to it. [Robert Thau]
12931 *) Logs access failures due to symlink checks or invalid client address
12932 in the error log [Roy Fielding, Robert Thau]
12934 *) Symlink checks deal correctly with systems where lstat of
12935 "/path/to/some/link/" follows the link. [Thau, Fielding]
12937 *) Doesn't reset DirectoryIndex to 'index.html' when
12938 other directory options are set in a .htaccess file. [Robert Thau]
12940 *) Clarified init code and nuked bogus warning in mod_access.c
12941 [Florent Guillaume]
12943 *) Corrected several directives in sample srm.conf
12944 --- includes corrections to directory indexing icon-related directives
12945 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
12946 icons for encodings right, and turning on AddEncoding by default).
12949 *) Corrected descriptions of args to AddIcon and AddAlt in command table
12952 *) INSTALL & README mention "contributed modules" directory [Brian
12955 *) Fixed English in the license language... "for for" --> "for".
12958 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
12959 mod_alias.c, merging it almost completely with handling of Alias, and
12960 adding a 'notes' field to the request_rec which allows the CGI module
12961 to discover whether the Alias module has put this request through
12962 ScriptAlias (which it needs to know for back-compatibility, as the old
12963 NCSA code did not check Options ExecCGI in ScriptAlias directories).
12966 Changes with Apache 0.8.10 18 Aug 1995
12968 *) AllowOverride applies to the named directory, and not just
12969 subdirectories. [David Robinson]
12971 *) Do locking for accept() exclusion (on systems that need it)
12972 using a special file created for the purpose in /usr/tmp, and
12973 not the error log; using the error log causes real problems
12974 if it's NFS-mounted; this is known to be the cause of a whole
12975 lot of "server hang" problems with Solaris. [David Robinson;
12976 thanks to Merten Schumann for help diagnosing the problem].
12978 Changes with Apache 0.8.9 12 Aug 1995
12980 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
12982 *) Nested includes see environment variables of the including document,
12983 for NCSA bug-compatibility (some sites have standard footer includes
12984 which try to print out the last-modified date). [Eric Hagberg/Robert
12987 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
12988 URI as a CGI script, even if it would have been treated as something
12989 else if requested directly, for NCSA back-compatibility. (Note that
12990 this means that people who know the name of the script can see the
12991 code just by asking for it). [Robert Thau]
12993 *) New version of dbmmanage script included in support directory as
12996 *) Check if scoreboard file couldn't be opened, and say so, rather
12997 then going insane [David Robinson]
12999 *) POST to CGI works on A/UX [Jim Jagielski]
13001 *) AddIcon and AddAlt commands work properly [Rob Hartill]
13003 *) NCSA server push works properly --- the Arena bug compatibility
13004 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
13005 if you still want the workaround). [Rob Hartill]
13007 *) If client didn't submit any Accept-encodings, ignore encodings in
13008 content negotiation. (NB this will all have to be reworked anyway
13009 for the new HTTP draft). [Florent Guillaume]
13011 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
13013 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
13015 *) Give Redirect priority over Alias, for NCSA bug compatibility
13018 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
13019 paralleling earlier bug fix for CGI [David Robinson]
13021 *) If DBM auth is improperly configured, report a server error and don't
13024 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
13025 it seems to work well enough without it (even in a 10 hits/sec
13026 workout), and the overhead for the locking under A/UX is
13027 alarmingly high (though it is very low on other systems).
13028 [Eric Hagberg, Jim Jagielski]
13030 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
13032 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
13033 Behlendorf/Eric Hagberg]
13035 *) More improvements to default Configuration for A/UX [Jim Jagielski]
13037 *) Compiles clean on NEXT [Rob Hartill]
13039 *) Compiles clean on SGI [Robert Thau]
13041 Changes with Apache 0.8.8 08 Aug 1995
13043 *) SunOS library prototypes now never included unless explicitly
13044 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
13045 people using GNU libc on SunOS are screwed by prototypes for the
13048 (Those who wish to compile clean with gcc -Wall on a standard
13049 SunOS setup need the prototypes, and may obtain them using
13050 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
13051 with nonstandard libraries are presumably competent to make their
13054 *) Strips trailing '/' characters off both args to the Alias command,
13055 to make 'Alias /foo/ /bar/' work.
13057 Changes with Apache 0.8.7 03 Aug 1995
13059 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
13060 [reported by David Robinson]
13062 *) Compiles clean on OSF/1 [David Robinson]
13064 *) Added some of the more recent significant changes (AddLanguage stuff,
13065 experimental LogFormat support) to CHANGES file in distribution root
13068 Changes with Apache 0.8.6 02 Aug 1995
13070 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
13071 (If you actually wanted a conditional GET which bypassed the cache, you
13072 couldn't get it). [Reported by Roy Fielding]
13074 *) Properly terminate headers on '304 Not Modified' replies to conditional
13075 GETs --- no browser we can find cares much, but the CERN proxy chokes.
13076 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
13078 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
13080 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
13081 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
13082 and older versions don't set the __SUNPRO_C preprocessor variable). On
13083 all other systems, these are never used anyway. [Reported by Mark Cox].
13085 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
13087 Changes with Apache 0.8.5 01 Aug 1995
13089 *) Added last-minute configurable log experiment, as optional module
13091 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
13092 properly. (One-line fix to http_protocol.c).
13094 *) Work around bogus behavior when reloading from Netscape.
13095 It's Netscape's bug --- for some reason they expect a request with
13096 If-modified-since: to not function as a conditional GET if it also
13097 comes with Pragma: no-cache, which is way out of line with the HTTP
13098 spec (according to Roy Fielding, the redactor).
13100 *) Added parameter to set maximum number of server processes.
13102 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
13105 *) IdentityCheck bugfix [Chuck Murcko].
13107 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
13109 *) More sample config file corrections; add extension to AddType for
13110 *.asis, move AddType generic description to its proper place, and
13111 fix miscellaneous typos. [ Alexei Kosut ]
13113 *) Deleted the *other* reference to the regents from the Berkeley
13114 legal disclaimer (everyplace).
13116 *) Nuked Shambhala name from src/README; had already cleaned it out
13117 of everywhere else.
13119 Changes with Apache 0.8.4
13121 *) Changes to server-pool management parms --- renamed current
13122 StartServers to MinSpareServers, created separate StartServers
13123 parameter which means what it says, and renamed MaxServers to
13124 MaxSpareServers (though the old name still works, for NCSA 1.4
13125 back-compatibility). The old names were generally regarded as
13126 too confusing. Also altered "docs" in sample config files.
13128 *) More improvements to default config files ---
13129 sample directives (commented out) for XBitHack, BindAddress,
13130 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
13131 defaults, AddTypes for send-as-is and imagemap magic types, and
13132 improvements to samples for DirectoryIndex [Alexei Kosut]
13134 *) Yet more improvements to default config files --- changes to
13135 Alexei's sample AddLanguage directives, and sample LanguagePriority
13136 [ Florent Guillaume ]
13138 *) Set config file locations properly if not set in httpd.conf
13141 *) Don't escape URIs in internal redirects multiple times; don't
13142 do that when translating PATH_INFO to PATH_TRANSLATED either.
13145 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
13147 Changes with Apache 0.8.3
13149 *) Edited distribution README to *briefly* summarize installation
13150 procedures, and give a pointer to the INSTALL file in the src/
13153 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
13154 recent NCSA distributions.
13156 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
13157 exist for the same directory, use both and don't segfault. [Reported
13160 *) Proper makefile dependencies [David Robinson]
13162 *) Note (re)starts in error log --- reported by Rob Hartill.
13164 *) Only call no2slash() after get_path_info() has been done, to
13165 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
13166 reported by Andrew Wilson, though this one is probably a real bug]
13168 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
13169 dump core when Referer is not supplied. [Randy Terbush]
13171 *) Lightly edited sample config files to refer people to our documentation
13172 instead of NCSA's, and to list Rob McCool as *original* author (also
13173 deleted his old, and no doubt non-functional email address). Would be
13174 nice to have examples of new features...
13176 Changes with Apache 0.8.2 19 Jul 1995
13178 *) Added AddLanuage code [Florent Guillaume]
13180 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
13182 *) All sorts of problems when MultiViews finds a directory. It would
13183 be nice if mod_dir.c was robust enough to handle that, but for now,
13184 just punt. [reported by Brian Behlendorf]
13186 *) Wait for all children on restart, to make sure that the old socket
13187 is gone and we can reopen it. [reported by Randy Terbush]
13189 *) Imagemap module is enabled in default Configuration
13191 *) RefererLog and UserAgentLog modules properly default the logfile
13194 *) Mark Cox's mod_cookies added to the distribution as an optional
13195 module (commented out in the default Configuration, and noted as
13196 an experiment, along with mod_dld). [Mark Cox]
13198 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
13200 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
13202 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
13204 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
13207 Changes with Apache 0.8.1
13209 *) New imagemap module [Randy Terbush]
13211 *) Replacement referer log module with NCSA-compatible RefererIgnore
13212 [Matthew Gray again]
13214 *) Don't mung directory listings with very long filenames.
13215 [Florent Guillaume]
13217 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
13219 *) New config script. See INSTALL for info. [Robert Thau]
13221 *) Scoreboard mechanism for regulating the number of extant server
13222 processes. MaxServers and StartServers defaults are the same as
13223 for NCSA, but the meanings are slightly different. (Actually,
13224 I should probably lower the MaxServers default to 10).
13226 Before asking for a new connection, each server process checks
13227 the number of other servers which are also waiting for a
13228 connection. If there are more than MaxServers, it quietly dies
13229 off. Conversely, every second, the root, or caretaker, process
13230 looks to see how many servers are waiting for a new connection;
13231 if there are fewer than StartServers, it starts a new one. This
13232 does not depend on the number of server processes already extant.
13233 The accounting is arranged through a "scoreboard" file, named
13234 /tmp/htstatus.*, on which each process has an independent file
13235 descriptor (they need to seek without interference).
13237 The end effect is that MaxServers is the maximum number of
13238 servers on an *inactive* server machine, but more will be forked
13239 off to handle unusually heavy loads (or unusually slow clients);
13240 these will die off when they are no longer needed --- without
13241 reverting to the overhead of full forking operation. There is a
13242 hard maximum of 150 server processes compiled in, largely to
13243 avoid forking out of control and dragging the machine down.
13244 (This is arguably too high).
13246 In my server endurance tests, this mechanism did not appear to
13247 impose any significant overhead, even after I forced it to put the
13248 scoreboard file on a normal filesystem (which might have more
13249 overhead than tmpfs). [Robert Thau]
13251 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
13254 *) Read .htaccess files even in directory with <Directory> section.
13255 (Former incompatibility noted on mailing list, now fixed). [Robert
13258 *) "HEAD /" gives the client a "Bad Request" error message, rather
13259 than trying to send no body *and* no headers. [Cliff Skolnick].
13261 *) Don't produce double error reports for some very obscure cases
13262 mainly involving auth configuration (the "all modules decline to
13263 handle" case which is a sure sign of a server bug in most cases,
13264 but also happens when authentication is badly misconfigured).
13267 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
13268 it's *for*, and this sort of thing really shouldn't be cluttering
13269 up the Makefile). [Robert Thau]
13271 *) Incidental code cleanups in http_main.c --- stop dragging
13272 sa_client around; just declare it where used. [Robert Thau]
13274 *) Another acc-related fix. (It doesn't like const char
13275 in some places...). [Mark Cox]
13277 Changes with Shambhala 0.6.1 13 Jul 1995
13279 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
13280 Also, fixed auth typo in http_protocol.c unmasked by this fix.
13282 *) Compiles clean with acc on SunOS [Paul Sutton]
13284 *) Reordered modules in modules.c so that Redirect takes priority
13285 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
13286 believe it or not, he has an actual site with a ScriptAlias and
13287 a Redirect declared for the *exact same directory*. Even *my*
13288 compatibility fetish wouldn't motivate me to fix this if the fix
13289 required any effort, but it doesn't, so what the hey.
13291 *) Fixed to properly default several server_rec fields for virtual
13292 servers from the corresponding fields in the main server_rec.
13293 [Cliff Skolnick --- 'port' was a particular irritant].
13295 *) No longer kills off nph- child processes before they are
13296 finished sending output. [Matthew Gray]
13298 Changes with Shambhala 0.6.0 10 Jul 1995
13300 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
13301 the connection to the client in an "aborted" state, but otherwise
13302 allow whatever handlers are running to clean up. hard_timeout()s
13303 abort the request in progress completely; anything not tied to some
13304 resource pool cleanup will leak. They're still around because I
13305 haven't yet come up with a more elegant way of handling
13306 timeouts when talking to something that isn't the client. The
13307 default_handler and the dir_handler now use soft timeouts, largely
13308 so I can test the feature. [Robert Thau]
13310 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
13311 the case of log handlers dying prematurely is probably handled VERY
13312 gracelessly at this point, and if the logger stops reading input,
13313 the server will hang. (It is known to correctly restart the
13314 logging process on server restart; this is (should be!) going through
13315 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
13316 script). [Robert Thau]
13318 *) asis files supported (new module). [Robert Thau]
13320 *) IdentityCheck code is compiled in, but has not been tested. (I
13321 don't know anyone who runs identd). [Robert Thau]
13323 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
13324 came in with the request, for NCSA bug-compatibility. [Robert Thau]
13326 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
13328 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
13329 as timeouts are not in scope. [Robert Thau]
13331 *) quoted-string args in config files now handled correctly (doesn't drop
13332 the last character). [Robert Thau; reported by Randy Terbush]
13334 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
13335 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
13337 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
13338 default default type); the former default default behavior when all
13339 type-checkers defaulted had been a core dump. [Paul Sutton]
13341 *) Copy filenames out of the struct dirent when indexing
13342 directories. (On Linux, readdir() returns a pointer to the same
13343 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
13345 Changes with Shambhala 0.5.3 [not released]
13347 *) Default response handler notes "file not found" in the error log,
13348 if the file was not found. [Cliff Skolnick].
13350 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
13351 code no longer sets up bogus PATH_INFO which fakes out the directory
13352 handler). [Cliff Skolnick]
13354 Changes with Shambhala 0.5.2 06 Jul 1995
13356 *) Changes to http_main.c --- root server no longer plays silly
13357 games with SIGCHLD, and so now detects and replaces dying
13358 children. Child processes just die on SIGTERM, without taking
13359 the whole process group with them. Potential problem --- if any
13360 child process refuses to die, we hang in restart.
13361 MaxRequestsPerChild may still not work, but it certainly works
13362 better than it did before this! [Robert Thau]
13364 *) mod_dir.c bug fixes: ReadmeName and HeaderName
13365 work (or work better, at least); over-long description lines
13366 properly terminated. [Mark Cox]
13368 *) http_request.c now calls unescape_url() more places where it
13369 should [Paul Sutton].
13371 *) More directory handling bugs (reported by Cox)
13372 Parent Directory link is now set correctly. [Robert Thau]
13374 Changes with Shambhala 0.5.1 04 Jul 1995
13376 *) Generalized cleanup interface in alloc.c --- any function can be
13377 registered with alloc.c as a cleanup for a resource pool;
13378 tracking of files and file descriptors has been reimplemented in
13379 terms of this interface, so I can give it some sort of a test.
13382 *) More changes in alloc.c --- new cleanup_for_exec() function,
13383 which tracks down and closes all file descriptors which have been
13384 registered with the alloc.c machinery before the server exec()s a
13385 child process for CGI or <!--#exec-->. CGI children now get
13386 started with exactly three file descriptors open. Hopefully,
13387 this cures the problem Rob H. was having with overly persistent
13388 CGI connections. [Robert Thau]
13390 *) Mutual exclusion around the accept() in child_main() --- this is
13391 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
13392 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
13393 This uses fcntl(F_SETLK,...) on the error log descriptor because
13394 flock() on that descriptor won't work on systems which have BSD
13395 flock() semantics, including (I think) Linux 1.3 and Solaris.
13397 This does work on SunOS (when the server is idle, only one
13398 process in the pool is waiting on accept()); it *ought* to work
13399 on the other systems. [Robert Thau]
13401 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
13403 *) sizeof(*sa_client) bugfix from [Rob Hartill]
13405 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
13407 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
13408 be unnecessary if I go to the revised timeout-handling scheme).
13411 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
13412 string) even if none came in with the request. [Robert Thau]
13414 *) CHANGES file added to distribution ;-).
13416 Changes with Shambhala 0.4.5
13418 *) mod_dld --- early dynamic loading support [rst]
13419 *) Add wildcard content handlers for XBITHACK; default_hander now
13420 invoked with that mechanism (as a handler hanging off mod_core) [rst]
13421 *) XBITHACK supported as a wildcard content-handler, and
13422 configurable at run-time (not just at compile time, as in the
13423 "patchy server" releases) [rst]
13425 Changes with Shambhala 0.4.4 30 Jun 1995
13427 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
13428 *) Handle Addtype x/y .z [rst, reported by Cox]
13430 Changes with Shambhala 0.4.3
13432 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
13433 synonymous [rst, terbush]
13435 Changes with Shambhala 0.4.1 28 Jun 1995
13437 *) First-cut virtual host implementation; some refit in the config
13438 reading code, and log management, was necessary to support this [rst]
13439 *) Sub-pool machinery, originally added to avoid excessive storage
13440 allocation on listings of large directories (which turned out to
13441 be the problem that the 0.3 storage accounting was added to
13442 find). Subrequests and mod_dir changed to use subpools. [rst]
13443 *) More memory debugging --- free list consistency checks. [rst]
13444 *) Added err_headers to request_rec, with support elsewhere [rst]
13445 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
13447 Changes with Shambhala 0.3 19 Jun 1995
13449 *) Switch ONE_PROCESS to a runtime command-line option (-X)
13450 *) Don't compile in mod_ai_backcompat by default
13451 *) Switch name of server from Apache to Shambhala in Makefile
13452 *) Add some accounting routines to track memory usage in the pools,
13455 Changes with Shambhala 0.2
13457 *) Set DOCUMENT_ROOT CGI variable
13458 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
13459 *) Add critical section protection to handling of cleanup structures
13461 *) Significant code reorg within the server core to group related
13462 functions together [rst]
13463 *) Correctly handle clients that hang up before sending any request
13465 *) Replace dying child processes. [rst]
13467 Changes with Shambhala 0.1 12 Jun 1995
13469 Major rewrite of the pre-existing "patchy server" codebase, by
13470 Robert Thau (rst). Significant portions of the server code, such
13471 as configuration-file handling and HTTP authentication support,
13472 were ripped out and rewritten from scratch. Code that was not
13473 completely rewritten was significantly altered.
13475 Major changes with this release include:
13477 *) Introduction of the module API; in request handling, the central
13478 machinery just dispatches to various modules, which actually do
13479 most of the work. Configuration handling is similar --- modules
13480 declare their own commands, and the central machinery just
13481 dispatches to them.
13483 API features from shambhala/0.1 were substantially unchanged in
13484 Apache 1.0 and 1.1. (1.0 API features not yet present in this
13485 release, such as wildcard handlers and subpools, were added in
13486 subsequent Shambhala releases, and were also generally rst's
13489 *) This release included the following modules:
13491 mod_access (access control --- allow and deny directives),
13492 mod_alias (Alias and Redirect commands),
13493 mod_auth (straight HTTP authentication, based on flat-files)
13494 mod_auth_dbm (same, with dbm files)
13495 mod_cgi (CGI scripts and, in this release, ScriptAlias)
13496 mod_common_log (CLF access logs; later renamed mod_log_common)
13497 mod_dir (directory indexing)
13498 mod_include (server-side includes)
13499 mod_mime (AddType directives)
13500 mod_negotiation (content negotiation)
13501 mod_userdir (support for users' public_html directories)
13503 It also included a mod_ai_backcompat, which was a private hack
13504 for back-compatibility with rst's own AI-lab servers.
13506 All of these modules were substantially complete, and functional
13507 or nearly so (a few, which implemented features not in use at
13508 Thau's site, required patches of a few lines).
13510 *) sub-request machinery, to allow modules to determine how other
13511 modules would assign MIME types to a given file, or optionally
13512 serve its content (this is heavily used by mod_dir, mod_include
13513 and mod_negotiation).
13515 *) Resource pool system for keeping track of memory allocated and
13516 files opened in service of a particular request. Much of the
13517 code in the modules (when they weren't rewrites) was adjusted to
13518 replace a pervasive convention of using fixed-size buffers on
13519 the stack with an equally pervasive convention of using memory
13520 allocated with palloc().
13522 *) Reorganization of data structures associated with a given
13523 request to eliminate use of global variables and the troublesome
13524 unmunge_name function (used in NCSA and early Apache releases to
13525 attempt to determine the URI which mapped to a given filename
13526 --- a difficult proposition, given that it is easy to produce
13527 setups in which multiple URIs map to the same file).
13529 *) Source files renamed and rearranged
13531 *) Very simple pre-forking behavior --- parent process forked off a
13532 fixed number of children, and then just waited for SIGHUP.
13534 *) Other more minor changes too numerous to list.
13536 This release included modified versions of a lot of code from the
13537 Apache 0.6.4 public release, plus an early pre-forking patch
13538 codeveloped by Robert Thau and Rob Hartill.
13540 Changes with Apache 0.7.3 20 Jun 1995
13542 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
13543 were incorporated by Rob Hartill on the main branch while Robert Thau
13544 worked on the Shambhala rewrite above. Most were merged into the
13545 Shambala architecture after Apache 0.8.0.
