5 *) Make REMOTE_PORT variable available in mod_rewrite.
8 *) Allow unescaped error logs via compile time switch
9 "-DAP_UNSAFE_ERROR_LOG_UNESCAPED".
10 [Geoffrey Young <geoff modperlcookbook.org>, André Malo]
12 *) proxy_http fix: mod_proxy hangs when both KeepAlive and
13 ProxyErrorOverride are enabled, and a non-200 response without a
14 body is generated by the backend server. (e.g.: a client makes a
15 request containing the "If-Modified-Since" and "If-None-Match"
16 headers, to which the backend server respond with status 304.)
17 [Graham Wiseman <gwiseman fscinternet.com>, Richard Reiner]
19 *) mod_ssl: Add support for distributed session cache using 'distcache'.
20 [Geoff Thorpe <geoff geoffthorpe.net>]

23 the Request-URI. PR 21779. [Amit Athavale <amit_athavale lycos.com>]
25 *) Add forensic logging module (mod_log_forensic).
28 *) Fix segfault in mod_mem_cache cache_insert() due to cache size
29 becoming negative. PR: 21285, 21287
30 [Bill Stoddard, Massimo Torquati, Jean-Jacques Clar]
32 *) mod_proxy with ProxyErrorOverride On in a reverse-proxy configuration attaches
33 a body to the 302 response and a wrong Content-Length header.
34 PR: 22951 [Ermanno Scaglione scaglione ..at.. starnetone.de]
36 *) Bring ErrorHeader concept forward from 1.3, so that response
37 header fields can be set for return even on errors or external
40 *) Fix some piped log problems: bogus "piped log program '(null)'
41 failed" messages during restart and problem with the logger
42 respawning again after Apache is stopped. PR 21648, PR 24805.
45 *) Fix <Limit> and <LimitExcept> parsing to require a closing '>'
46 in the initial container. PR 25414.
47 [Geoffrey Young <geoff apache.org>]
49 *) Clean up httpd -V output: Instead of displaying the MPM source
50 directory, display the MPM name and some MPM properties.
51 [Geoffrey Young <geoff apache.org>]
53 *) Fixed cache-removal order in mod_mem_cache.
54 [Jean-Jacques Clar, Cliff Woolley]
56 *) Add fatal exception hook for use by debug modules. The hook is only
57 available if the --enable-exception-hook configure parm is used.
60 *) mod_ssl/mod_status: Re-enable support for output of SSL session
61 cache information in server-status page. [Joe Orton]

76 [Matthieu Estrade <apache moresecurity.org>]
78 *) mod_setenvif: Fix the regex optimizer, which under circumstances
79 treated the supplied regex as literal string. PR 24219.
82 *) Log an error when requests for URIs which fail to map to a valid
83 filesystem name are rejected with 403. [Jeff Trawick]
85 *) Switch to APR 1.0 API.
87 *) Fix mod_include's expression parser to recognize strings correctly
88 even if they start with an escaped token. [André Malo]
90 *) Major overhaul of mod_include's filter parser. The new parser code
91 is expected to be more robust and should catch all of the edge cases
92 that were not handled by the previous one. This includes a binary
93 incompatible change of mod_include's external API. [André Malo]
95 *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
96 PR 14223. [André Malo]
98 *) mod_rewrite: Catch an edge case, where strange subsequent RewriteRules
99 could lead to a 400 (Bad Request) response. [André Malo]
101 *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously
102 the current rewrite state was just used as lookup path, which lead to
103 strange and often useless results. Related to PR 8493. [André Malo]
105 *) Change Listen directive to bind to all addresses when a hostname is
106 not specified. [Justin Erenkrantz]
108 *) Correct failure with Listen directives on machines with IPv6 enabled.
109 [Colm MacCárthaigh <colm stdlib.net>, Justin Erenkrantz]
111 *) Fix a link failure in mod_ssl when the OpenSSL libraries contain
112 the ENGINE functions but the engine header files are missing.
115 *) mod_rewrite: RewriteRules in server context using the force
116 type feature [T=...] no longer disable MultiViews. [André Malo]
118 *) mod_rewrite: Allow piped rewrite logs to be relative to ServerRoot.
121 *) mod_authz_groupfile: Strip trailing spaces of group names. This
122 hopefully saves some hours of searching for typos. PR 12863.
125 *) mod_actions: Propagate the handler name to the action script via
126 the REDIRECT_HANDLER environment variable. [André Malo]
128 *) mod_actions: Introduce the "virtual" modifier to the Action directive,
129 which allows the use of handlers for virtual locations. PR 8431.
132 *) mod_speling: Recognize AcceptPathInfo setting for the particular
133 location. Default is to reject path information. PR 21059.
136 *) mod_ext_filter: Add the ability to filter request bodies.
137 [Philipp Reisner <philipp.reisner linbit.com>]

148 *) prefork MPM: Use the right permissions for the directory created
149 for gprof support. [Jim Carlson <jcarlson jnous.com>]
151 *) Fix a compile failure with recent OpenSSL and picky compilers
152 (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
154 *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
155 the INCLUDE path to be defined properly.
156 PR 11310. [Geoff Thorpe <geoff geoffthorpe.net>]
158 *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
160 *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
161 autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc).
162 [Geoff Thorpe <geoff geoffthorpe.net>]
164 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
165 [Ian Holsman, André Malo]
167 *) mod_negotiation: quality values are now parsed independent from
168 the current locale. level values are now really parsed as integers.
169 PR 17564. [André Malo]
171 *) Added the WindowsSocketsWorkaround directive for Windows NT/2000/XP
172 to work around problems with certain VPN and Firewall products that
173 have buggy AcceptEx implementations.
174 [Allan Edwards w/ suggestions from Bill Stoddard & Bill Rowe]
176 *) Extend mod_negotiation to evaluate the environment variables
177 no-gzip and gzip-only-text/html the same way as mod_deflate does.
180 *) mod_rewrite: Fix some problems reporting errors with mapping
181 programs (RewriteMap prg:/something). [Jeff Trawick]
183 *) Return 413 if chunk-ext-header is too long rather than reading from
184 the truncated line. PR 15857. [Justin Erenkrantz]
186 *) Allow restart of httpd to occur even with syntax errors in the config
187 file. PR 16813. [Justin Erenkrantz]
189 *) Use APR_LAYOUT instead of APACHE_LAYOUT in configure. PR 15679.
192 *) Remove files on 'make distclean' that should be. PR 15592.
195 *) Allow apachectl to perform status with links and elinks as well.
198 *) Extend the SetEnvIf directive to capture subexpressions of the
199 matched value. [André Malo]
201 *) mod_log_config change optional hook to return previous handler
204 *) Forward port of mod_actions' ability to handle arbitrary methods
205 with the Script directive. [André Malo]
207 *) Let suexec send a message to stderr, if it failed or its policy
208 was violated. This message appears in the error log and allows
209 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
211 *) Modify buildconf to copy all required files into httpd's tree.
212 [Thom May <thom planetarytramp.net>]
214 *) Allow mod_dav to do weak entity comparison functions.
217 *) Move RFC 1413 ident requests from core to new module mod_ident.
220 *) Add mod_authz_owner - a forward port of "Require file-owner"
221 and "Require file-group", which was already present in version
224 *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
227 *) Replace some of the mutex locking in the worker MPM with
228 atomic operations for higher concurrency. [Brian Pane]
230 *) Allow 'make depend' to work with non-GCC compilers.
233 *) If an httpd.conf has commented out AddModule directives,
234 apxs -i -a will add an un-commented AddModule directive for
235 the new module, which breaks the config.
236 PR: 11212 [Joe Orton]
238 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
240 *) Move the check of the Expect request header field after the hook
241 for ap_post_read_request, since that is the only opportunity for
242 modules to handle Expect extensions. [Justin Erenkrantz]
244 *) Rewrite of aaa modules to an authn/authz model.
245 [Dirk-Willem van Gulik, Justin Erenkrantz]
248 [Apache 2.1.0-dev includes those bug fixes and changes with the
249 Apache 2.0.xx tree as documented, and except as noted, below.]

274 *) Backport major overhaul of mod_include's filter parser from 2.1.
275 The new parser code is expected to be more robust and should
276 catch all of the edge cases that were not handled by the previous one.
277 The 2.1 external API changes were hidden by a wrapper which is
278 expected to keep the API backwards compatible. [André Malo]
280 *) Add a hook (insert_error_filter) to allow filters to re-insert
281 themselves during processing of error responses. Enable mod_expires
282 to use the new hook to include Expires headers in valid error
283 responses. This addresses an RFC violation. It fixes PRs 19794,
284 24884, and 25123. [Paul J. Reder]
286 *) Add Polish translation of error messages. PR 25101.
287 [Tomasz Kepczynski <tomek jot23.org>]
289 *) Add AP_MPMQ_MPM_STATE function code for ap_mpm_query. (Not yet

307 *) Correct UseCanonicalName Off to properly check incoming port number.
310 *) Fix slow graceful restarts with prefork MPM. [Joe Orton]
312 *) Fix a problem with namespace mappings being dropped in mod_dav_fs;
313 if any property values were set which defined namespaces these
314 came out mangled in the PROPFIND response. PR 11637.
315 [Amit Athavale <amit_athavale persistent.co.in>]
317 *) mod_dav: Return a WWW-auth header for MOVE/COPY requests where
318 the destination resource gives a 401. PR 15571. [Joe Orton]
320 *) SECURITY [CAN-2003-0020]: Escape arbitrary data before writing
321 into the errorlog. [André Malo]
323 *) mod_autoindex / core: Don't fail to show filenames containing
324 special characters like '%'. PR 13598. [André Malo]

333 limit on the amount of storage used by the bucket brigades
334 in each server thread. [Bill Stoddard]

337 fixed a number of other cache code bugs related to PR 15852.
338 Includes a patch submitted by Sushma Rai <rsushma novell.com>.
339 This fixes mod_mem_cache but not mod_disk_cache yet so I'm not
340 closing the PR since that is what they are using. [Paul J. Reder]
342 *) complain via error_log when mod_include's INCLUDES filter is
343 enabled, but the relevant Options flag allowing the filter to run
344 for the specific resource wasn't set, so that the filter won't
345 silently get skipped. next remove itself, so the warning will be
346 logged only once [Stas Bekman, Jeff Trawick, Bill Rowe]
348 *) mod_info: HTML escape configuration information so it displays
349 correctly. PR 24232. [Thom May]

364 are also loaded. [Joe Orton]
366 *) mod_ssl: Use human-readable OpenSSL error strings in logs; use
367 thread-safe interface for retrieving error strings. [Joe Orton]
369 *) mod_expires: Initialize ExpiresDefault to NULL instead of "" to
370 avoid reporting an Internal Server error if it is used without
371 having been set in the httpd.conf file. PR: 23748, 24459
372 [Andre Malo, Liam Quinn <liam htmlhelp.com>]
374 *) mod_autoindex: Don't omit the <tr> start tag if the SuppressIcon
375 option is set. PR 21668. [Jesse Tie-Ten-Quee <highos highos.com>]
377 *) mod_include no longer allows an ETag header on 304 responses.
378 PR 19355. [Geoffrey Young <geoff apache.org>, André Malo]
380 *) EBCDIC: Convert header fields to ASCII before sending (broken
381 since 2.0.44). [Martin Kraemer]
383 *) Fix the inability to log errors like exec failure in
384 mod_ext_filter/mod_cgi script children. This was broken after
385 such children stopped inheriting the error log handle.
388 *) Fix mod_info to use the real config file name, not the default
389 config file name. [Aryeh Katz <aryeh secured-services.com>]

393 instead of 'W'. [Jeff Trawick]
395 Changes with Apache 2.0.48
397 *) SECURITY [CAN-2003-0789]: mod_cgid: Resolve some mishandling of
398 the AF_UNIX socket used to communicate with the cgid daemon and
399 the CGI script. [Jeff Trawick]
401 *) SECURITY [CAN-2003-0542]: Fix buffer overflows in mod_alias and
402 mod_rewrite which occurred if one configured a regular expression
403 with more than 9 captures. [André Malo]
405 *) mod_include: fix segfault which occured if the filename was not
406 set, for example, when processing some error conditions.
407 PR 23836. [Brian Akins <bakins web.turner.com>, André Malo]
409 *) fix the config parser to support <Foo>..</Foo> containers (no
410 arguments in the opening tag) supported by httpd 1.3. Without
411 this change mod_perl 2.0's <Perl> sections are broken.
412 ["Philippe M. Chiasson" <gozer cpan.org>]
414 *) mod_cgid: fix a hash table corruption problem which could
415 result in the wrong script being cleaned up at the end of a
416 request. [Jeff Trawick]
418 *) Update httpd-*.conf to be clearer in describing the connection
419 between AddType and AddEncoding for defining the meaning of
420 compressed file extensions. [Roy Fielding]
422 *) mod_rewrite: Don't die silently when failing to open RewriteLogs.
423 PR 23416. [André Malo]
425 *) mod_rewrite: Fix mod_rewrite's support of the [P] option to send
426 rewritten request using "proxy:". The code was adding multiple "proxy:"
427 fields in the rewritten URI. PR: 13946.
428 [Eider Oliveira <eider bol.com.br>]
430 *) cache_util: Fix ap_check_cache_freshness to check max_age, smax_age, and
431 expires as directed in RFC 2616. [Thomas Castelle <tcastelle generali.fr>]

461 *) Fix a bug, where mod_deflate sometimes unconditionally compressed the
462 content if the Accept-Encoding header contained only other tokens than
463 "gzip" (such as "deflate"). PR 21523. [Joe Orton, André Malo]

482 *) Lower the severity of the "listener thread didn't exit" message
483 to debug, as it is of interest only to developers. PR 9011

487 [Cliff Woolley, Jean-Jacques Clar]
489 *) Install config.nice into the build/ directory to make
490 minor version upgrades easier. [Joshua Slive]
492 *) Fix mod_deflate so that it does not call deflate() without checking
493 first whether it has something to deflate. (Currently this causes
494 deflate to generate a fatal error according to the zlib spec.)
495 PR 22259. [Stas Bekman]
497 *) mod_ssl: Fix FakeBasicAuth for subrequest. Log an error when an
498 identity spoof is encountered.

543 *) mod_rewrite: Perform child initialization on the rewrite log lock.
544 This fixes a log corruption issue when flock-based serialization
545 is used (e.g., FreeBSD). [Jeff Trawick]
547 *) Don't respect the Server header field as set by modules and CGIs.
548 As with 1.3, for proxy requests any such field is from the origin
549 server; otherwise it will have our server info as controlled by
550 the ServerTokens directive. [Jeff Trawick]
552 Changes with Apache 2.0.47
554 *) SECURITY [CAN-2003-0192]: Fixed a bug whereby certain sequences
555 of per-directory renegotiations and the SSLCipherSuite directive
556 being used to upgrade from a weak ciphersuite to a strong one
557 could result in the weak ciphersuite being used in place of the
558 strong one. [Ben Laurie]
560 *) SECURITY [CAN-2003-0253]: Fixed a bug in prefork MPM causing
561 temporary denial of service when accept() on a rarely accessed port
562 returns certain errors. Reported by Saheed Akhtar
563 <S.Akhtar talis.com>. [Jeff Trawick]

568 <tsuneo.yoshioka f-secure.com>]
570 *) SECURITY [VU#379828] Prevent the server from crashing when entering
571 infinite loops. The new LimitInternalRecursion directive configures
572 limits of subsequent internal redirects and nested subrequests, after
573 which the request will be aborted. PR 19753 (and probably others).
574 [William Rowe, Jeff Trawick, André Malo]
576 *) core_output_filter: don't split the brigade after a FLUSH bucket if
577 it's the last bucket. This prevents creating unneccessary empty
578 brigades which may not be destroyed until the end of a keepalive
580 [Juan Rivera <Juan.Rivera citrix.com>]
582 *) Add support for "streamy" PROPFIND responses.
583 [Ben Collins-Sussman <sussman collab.net>]
585 *) mod_cgid: Eliminate a double-close of a socket. This resolves
586 various operational problems in a threaded MPM, since on the
587 second attempt to close the socket, the same descriptor was

822 and standardized the LDAP SSL support across the various LDAP SDKs.
823 Isolated the SSL functionality to mod_ldap rather than speading it
824 across mod_auth_ldap and mod_ldap. Also added LDAPTrustedCA
825 and LDAPTrustedCAType directives to mod_ldap to allow for a more
826 common method of specifying the SSL certificate.

1150 *) Fix streaming output from an nph- CGI script. CGI:IRC now
1151 works. PR 8482 [Jeff Trawick]
1153 *) More accurate logging of bytes sent in mod_logio when
1154 the client terminates the connection before the response
1155 is completely sent [Bojan Smojver <bojan rexursive.com>]

1158 [Jonas Eriksson <jonas webkonsulterna.com>]
1160 *) Change the CacheRoot processing to check for a required
1161 value at config time. This saves a lot of wasted processing
1162 if the mod_disk_cache module is loaded but no CacheRoot
1163 was provided. This fix also adds code to log an error
1164 and avoid useless pallocs and procesing when the computed
1165 cache file name cannot be opened. This also updates the
1166 docs accordingly. [Paul J. Reder]
1168 *) Introduce the EnableSendfile directive, allowing users of NFS
1169 shares to disable sendfile mechanics when they either fail
1170 outright or provide intermitantly corrupted data. PR

1178 *) Add the ProxyBadHeader directive, which gives the admin some
1179 control on how mod_proxy should handle bogus HTTP headers from
1180 proxied servers. This allows 2.0 to "emulate" 1.3's behavior if
1181 desired. [Jim Jagielski]

1206 *) SECURITY [CAN-2002-0840]: HTML-escape the address produced by
1207 ap_server_signature() against this cross-site scripting
1208 vulnerability exposed by the directive 'UseCanonicalName Off'.
1209 Also HTML-escape the SERVER_NAME environment variable for CGI
1210 and SSI requests. It's safe to escape as only the '<', '>',
1211 and '&' characters are affected, which won't appear in a valid
1212 hostname. Reported by Matthew Murphy <mattmurphy kc.rr.com>.
1215 *) Fix a core dump in mod_cache when it attemtped to store uncopyable
1216 buckets. This happened, for instance, when a file to be cached
1217 contained SSI tags to execute a CGI script (passed as a pipe
1218 bucket). [Paul J. Reder]
1220 *) Ensure that output already available is flushed to the network

1333 *) The content-length filter no longer tries to buffer up
1334 the entire output of a long-running request before sending
1335 anything to the client. [Brian Pane]
1337 *) Win32: Lower the default stack size from 1MB to 256K. This will

1393 *) Performance improvement for keepalive requests: when setting
1394 aside a small file for potential concatenation with the next
1395 response on the connection, set aside the file descriptor rather
1396 than copying the file into the heap. [Brian Pane]
1398 *) Modified version check on openssl so that it finds the executable
1399 first and then performs a check of the version, only warning the
1400 user if they chose, or we selected, an old version of OpenSSL.
1401 This change also allows the code to work for non-openssl libraries
1402 selected via the --with-ssl=dir option, which can override the
1403 automated library check in any case. [Roy Fielding]
1405 Changes with Apache 2.0.40
1407 *) SECURITY [CAN-2002-0661] (cve.mitre.org):
1408 Close a very significant security hole that
1409 applies only to the Win32, OS2 and Netware platforms. Unix was not
1410 affected, Cygwin may be affected. Certain URIs will bypass security
1411 and allow users to invoke or access any file depending on the system
1412 configuration. Without upgrading, a single .conf change will close
1413 the vulnerability. Add the following directive in the global server
1414 httpd.conf context before any other Alias or Redirect directives;
1415 RedirectMatch 400 "\\\.\."
1416 Reported by Auriemma Luigi <bugtest sitoverde.com>.
1419 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1420 Close a path-revealing exposure in multiview type
1421 map negotiation (such as the default error documents) where the
1422 module would report the full path of the typemapped .var file when
1423 multiple documents or no documents could be served based on the mime
1424 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
1427 *) SECURITY [CAN-2002-0654] (cve.mitre.org):

1440 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
1441 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
1443 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
1444 set to 1, so we can exclude things from the general case with
1445 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
1447 *) Accept multiple leading /'s for requests within the DocumentRoot.
1448 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
1450 *) Solved the reports of .pdf byterange failures on Win32 alone.
1451 APR's sendfile for the win32 platform collapses header and trailer
1452 buffers into a single buffer. However, we destroyed the pointers
1453 to the header buffer if a trailer buffer was present. PR 10781
1456 *) mod_ext_filter: Add the ability to enable or disable a filter via
1457 an environment variable. Add the ability to register a filter of
1458 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
1460 *) Restore the ability to specify host names on Listen directives.

1463 *) When deciding on the default address family for listening sockets,
1464 make sure we can actually bind to an AF_INET6 socket before
1465 deciding that we should default to AF_INET6. This fixes a startup
1466 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
1468 *) Replace usage of atol() to parse strings when we might want a
1469 larger-than-long value with apr_atoll(), which returns long long.
1470 This allows HTTPD to deal with larger files correctly.
1471 [Shantonu Sen <ssen apple.com>]
1473 *) mod_ext_filter: Ignore any content-type parameters when checking if
1474 the response should be filtered. Previously, "intype=text/html"
1475 wouldn't match something like "text/html;charset=8859_1".
1478 *) mod_ext_filter: Set up environment variables for external programs.
1479 [Craig Sebenik <craig netapp.com>]
1481 *) Modified the HTTP_IN filter to immediately append the EOS (end of
1482 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
1483 the caller to determine that no content remains without prefetching
1484 additional POST body. [William Rowe]

1511 *) Performance improvements for the code that reads request
1512 headers (ap_rgetline_core() and related functions) [Brian Pane]
1514 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
1515 to configure the maximum amount of memory the allocators will
1516 hold on to for reuse. Anything over the MaxMemFree threshold
1517 will be free()d. This directive is useful when uncommon large
1518 peaks occur in memory usage. It should _not_ be used to mask
1519 defective modules' memory use. [Sander Striker]
1521 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
1522 scripts would not result in a truncated response.
1523 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
1525 *) Add a filter_init parameter to the filter registration functions
1526 so that a filter can execute arbitrary code before the handlers
1527 are invoked. This resolves a problem where mod_include requests
1528 would incorrectly return a 304. [Justin Erenkrantz]
1530 *) Fix a long-standing bug in 2.0, CGI scripts were being called
1531 with relative paths instead of absolute paths. Apache 1.3 used
1532 absolute paths for everything except for SuExec, this brings back
1533 that standard. [Ryan Bloom]
1535 *) Fix infinite loop due to two HTTP_IN filters being present for
1536 internally redirected requests. PR 10146. [Justin Erenkrantz]
1538 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
1541 *) Fix mod_ext_filter to look in the main server for filter definitions
1542 when running in a vhost if the filter definition is not found in
1543 the vhost. PR 10147 [Jeff Trawick]
1545 *) Support WinNT CGI invocation through ScriptInterpreterSource
1546 'registry' for script interpreter paths and names with non-ascii
1547 characters in the executable filepath. [William Rowe]
1549 *) Support the -w flag on to keep the Win32 console open on error.
1552 *) Normalize the hostname value in the request_rec to all-lowercase
1553 [Perry Harrington <pedward webcom.com>]
1555 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
1556 extended characters (non US-ASCII) in non-utf8 format. This brings
1557 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
1558 to the cgi application itself. [William Rowe]
1560 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
1561 modules to bring them up to the current apr/apr-util APIs.
1564 *) Fix segfault in mod_mem_cache most frequently observed when
1565 serving the same file to multiple clients on an MP machine.
1568 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])

1581 *) Improve ap_get_client_block implementation by using APR-util brigade
1582 helper functions and relying on current filter assumptions.
1585 Changes with Apache 2.0.39

1590 Changes with Apache 2.0.38
1592 *) Rewrite htpasswd to use APR. The removes the annoying warning about
1593 tmpnam being unsafe. [Ryan Bloom]
1595 *) We must set the MIME-type for .shtml files to text/html if we want them
1596 to be parsed for SSI tags. Add the config for that to the default
1597 config file so that it is easier to enable .shtml parsing.

1600 *) Fixed a problem with 'make install' on ReliantUnix.
1601 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
1603 *) Make the default_handler catch all requests that aren't served by
1604 another handler. This also gets us to return a 404 if a directory
1605 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1606 loaded. [Justin Erenkrantz]
1608 *) Fixed the handling of nested if-statements in shtml files.
1609 PR 9866 [Brian Pane]
1611 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1612 into a directory different from the one that was configured. This
1613 also mirrors the root= feature from 1.3. We cannot use prefix=,
1614 because both APR and APR-util resolve their installation paths at
1615 configuration time. This means that there is no variable prefix
1616 to replace. [Andreas Hasenack <andreas netbank.com.br>]
1618 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1619 These levels of AIX don't have a thundering herd problem with
1620 accept(). [Jeff Trawick]
1622 *) prefork MPM: Ignore mutex errors during graceful restart. For
1623 certain types of mutexes (particularly SysV semaphores), we
1624 should expect to occasionally fail to obtain or release the
1625 mutex during restart processing. [Jeff Trawick]
1627 *) Fix install-bindist.sh so that it finds any perl instead of just
1628 early perl 5.x versions. This is consistent with a build/install
1629 from source, and it allows the perl scripts installed by a bindist
1630 to work on systems with perl 5.6. [Jeff Trawick]
1632 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
1633 Tru64 (and probably some other platforms). [Jeff Trawick]
1635 *) Allow CGI scripts to return their Content-Length. This also fixes a
1636 hang on HEAD requests seen on certain platforms (such as FreeBSD).
1639 *) Added log rotation based on file size to the RotateLog support
1640 utility. [Brad Nicholes]

1992 explicitly tell the server that warning messages should be sent
1993 to the client in addition to being recorded in the error log.
1994 Prior to this change, ap_log_rerror() always sent warning
1995 messages to the client. In one case, a faulty CGI script caused
1996 the server to send a warning message to the client that contained
1997 the full path to the CGI script. This could be considered a
1998 minor security exposure. [Bill Stoddard]

2014 *) Change instdso.sh to use libtool --install everywhere and then
2015 clean up some stray files and symlinks that libtool leaves around
2016 on some platforms. This gets subversion building properly since
2017 it needed a re-link to be performed by libtool at install time,

2031 cache entry. [Bill Stoddard]
2033 *) Introduced -E startup_logfile_name option to httpd to allow admins
2034 to begin logging errors immediately. This provides Win32 users
2035 an alternative to sending startup errors to the event viewer, and

2122 "<!--#" occurs at the very end of a bucket
2123 [Paul Reder, Brian Pane]
2125 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
2126 cause the Apache parent process to run in the foreground (similar to
2127 -DNO_DETACH except that it doesn't switch session ids).
2130 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
2131 for those platforms that support it. If using the default
2132 implementation, this is between pthread and sysvsem in priority.
2133 This implies it's the new default for Darwin. [Jim Jagielski]
2135 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
2136 environment variables in the envvars file. [Jeff Trawick]
2138 *) worker MPM: Don't create a listener thread until we have a worker

2221 *) Added exp_foo and rel_foo variables to config_vars.mk for
2222 all Apache and Autoconf path variables (like --sysconfdir,
2223 --sbindir, etc). exp_foo is the "expanded" version, which means
2224 that all internal variable references have been interpolated.
2225 rel_foo is the same as $exp_foo, only relative to $prefix if they
2226 share a common path. [Aaron Bannert]
2228 *) Fix some restart/terminate problems in the worker MPM. Don't
2229 drop connections during graceful restart. [Jeff Trawick]

2314 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
2315 when reading from a remote HTTP server in proxy. [Graham Leggett]
2317 *) Modify receive/send loop in proxy_http and proxy_ftp so that
2318 should it be necessary, the remote server socket is closed before
2319 transmitting the last buffer (set by ProxyIOBufferSize) to the
2320 client. This prevents the backend server from being forced to hang
2321 around while the last few bytes are transmitted to a slow client.

2363 *) Change mod_ssl to always do a full startup/teardown on restarts.
2364 this allows mod_ssl to be added to a server that is already
2365 running and makes it possible to add/change certs/keys after the
2366 server has been started. [Doug MacEachern]
2368 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
2369 This pipe must be a bidirectional 'console' style relay, which
2370 mod_ssl prints all prompts to the pipe's stdin, and reads the
2371 passphrases from the pipe's stdout. [William Rowe]
2373 *) Fix bug where --sysconfdir and --localstatedir were being
2374 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
2377 *) Fix --enable-layout to work again. Caution: When specifying
2378 --enable-layout, common arguments like --prefix, --exec-prefix,

2380 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]

2393 *) All instances of apr_lock_t have been removed and converted
2394 to one of the following new lock APIs: apr_thread_mutex.h,
2395 apr_proc_mutex.h, or apr_global_mutex.h. No new code should

2408 [Ryan Morgan <rmorgan covalent.net>]
2410 *) Fix for multiple file buckets on Win32, where the first file

2418 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
2419 multi-process mode to not "daemonize" while detaching from the

2435 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
2436 are now unmerged in the http proxy before being sent to the
2437 client. [Graham Leggett]
2439 *) Fix a problem with proxy where each entry of a duplicated
2440 header such as Set-Cookie would overwrite and obliterate the
2441 previous value of the header, resulting in multiple header
2442 values (like cookies) going missing.

2471 *) Add reference counting to mod_mem_cache cache objects to
2472 better manage removing objects from the cache.
2475 *) Change the verbage on the ScoreBoardFile in our default configs.
2476 Also change the default to be commented out (unspecified) so we
2477 get anonymous shared memory by default. [Aaron Bannert]
2479 *) Implement new ScoreBoardFile directive logic. This affects how
2480 we create the scoreboard's shared memory segment. If the directive
2481 is present, a name-based segment is created. If the directive is
2482 not present, first an anonymous segment is created, and if that
2483 fails, a name-based segment is created from a file of the name
2484 DEFAULT_SCOREBOARD. This gives third-party applications the
2485 ability to access our scoreboard. [Aaron Bannert]
2487 *) Allow mod_deflate to work with non-GET requests and properly send
2488 Content-Lengths. [Sander Striker <striker apache.org>]
2490 *) Fix ap_directory_merge() to correctly merge configs when there is
2491 no <Directory /> block. [Justin Erenkrantz, William Rowe]
2493 *) Remove spurious debug messsages that are normal under HTTP
2494 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
2496 *) Fix a bug in mod_cgid that would prevent proper shutdown death
2497 of the cgid process. [Aaron Bannert]
2499 *) Add signal handling back in to the worker MPM for the one_process
2500 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
2502 *) Performance: Reuse per-connection transaction pools in the
2503 worker MPM, rather than destroying and recreating them. [Brian Pane]
2505 *) Remove all signals from the worker MPM's child process. Instead,
2506 the parent uses the Pipe of Death for all communication with the
2507 child processes. [Ryan Bloom]
2509 Changes with Apache 2.0.32
2511 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
2512 default if the directive is not specified. This mirrors older
2513 behavior without changes to the httpd.conf. [William Rowe]
2515 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
2516 the service, mpm and logging code, and bugs in apr_file_open_stderr
2517 and apr_file_dup2 functions. Win2K/XP services have no handles
2518 associated for stdin/out/err, which caused unpredictable behavior
2519 in the prior release. [William Rowe, Bill Stoddard]
2521 *) Win32: simplify the Application Event Log messages, since there isn't
2522 likely to be 'more information in the error log' before an error log
2523 has been opened. [William Rowe]
2525 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
2526 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
2528 *) Win32: apache -k shutdown now behaves like apache -k stop.
2531 *) Fix prefork to not kill the parent if a child hits a resource shortage
2532 on accept(). [Greg Ames]
2534 *) Fix seg faults that occur when what should be the httpd request line
2535 starts with \r\n followed by garbage. [Greg Ames]
2537 *) Allow statically linked support binaries with the new
2538 --enable-static-support flag, and enable this behavior in
2539 the binbuild script. Also add a new --enable-static-htdbm
2540 flag. [Aaron Bannert]
2542 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
2543 do only one stat() call when generating the directory listings.
2546 *) Fix resolve_symlink to save the original symlink name if known.
2549 *) Be a bit more sane with regard to CanonicalNames. If the user has
2550 specified they want to use the CanonicalName, but they have not
2551 configured a port with the ServerName, then use the same port that
2552 the original request used. [Ryan Bloom and Ken Coar]
2554 *) In core_input_filter, check for an empty brigade after
2555 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
2556 client says it will post some data but we get FIN before any
2557 data arrives. [Jeff Trawick]
2559 *) Not being able to bind to the socket is a fatal error. We should
2560 print an error to the console, and return a non-zero status code.
2561 With these changes, all of the Unix MPMs do that correctly.
2564 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
2565 through to CGI scripts. PR 9163
2566 [Brian Reid <breid customlogic.com>,
2567 Zvi Har'El <rl math.technion.ac.il>]
2569 *) binbuild.sh: Make sure that we use the expat from our source
2570 tree so that there aren't any surprises on the target machine.
2573 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2574 enough to keep up with new requests. Start using
2575 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2576 when we can't talk to the daemon. [Jeff Trawick]
2578 *) apxs: LTFLAGS envvar can override default libtool options. Try
2579 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2580 the covers. [Jeff Trawick]
2582 *) The Location: response header field, used for external
2583 redirect, *must* be an absoluteURI. The Redirect directive
2584 tested for that, but RedirectMatch didn't -- it would allow
2585 almost anything through. Now it will try to turn an abs_path
2586 into an absoluteURI, but it will correctly varf like Redirect
2587 if the final redirection target isn't an absoluteURI. [Ken Coar]
2589 Changes with Apache 2.0.31
2591 *) Create the scoreboard (in the parent) in a global pool context,
2592 so it survives graceful restarts. This fixes a SEGV during
2593 graceful restarts. [Aaron Bannert]
2595 *) Add a timeout option to the proxy code 'ProxyTimeout'
2598 *) FTP directory listings are now always retrieved in ASCII mode.
2599 The FTP proxy properly escapes URI's and HTML in the generated
2600 listing, and escapes the path components when talking to the FTP
2601 server. It is now possible to browse the root directory by using
2602 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2603 Also, the last path component may contain wildcard characters
2604 '*' and '?', and if they do, a directory listing is created instead
2605 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2608 *) Added single-listener unserialized accept support to the
2609 worker MPM [Brian Pane]
2611 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2612 the incoming host header through to the proxied server
2613 [Geoff <g.russell ieee.org>]
2615 *) New Directive Option for ProxyPass. It now can block a location
2616 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
2618 *) Don't let the default handler try to serve a raw directory. At
2619 best you get gibberish. Much worse things can happen depending
2620 on the OS. [Jeff Trawick]
2622 *) Change the pre_config hook to return a value. Modules can now emit
2623 an error message and then cause the server to quit gracefully during
2624 startup. This required a bump to the MMN. [Aaron Bannert]
2626 *) Fix some unix socket descriptor leaks in the handler side of
2627 mod_cgid (the part that runs in the server process). Whack a
2628 silly "close(-1)" in the handler too. [Jeff Trawick]
2630 *) Change the pre_mpm hook to return a value, so that scoreboard
2631 init errors percolate up to code that knows how to exit
2632 cleanly. This required a bump to the MMN. [Jeff Trawick]
2634 *) Add the socket back to the conn_rec and remove the create_connection
2635 hook. The create_connection hook had a design flaw that did not
2636 allow creating connections based on vhost info. [Bill Stoddard]
2638 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2639 Resolves the common case of using negotation to resolve the request
2640 /script/foo for /script.cgi/foo. [William Rowe]
2642 *) Added new functions ap_add_(input|output)_filter_handle to
2643 allow modules to bypass the usual filter name lookup when
2644 adding hard-coded filters to a request [Brian Pane]
2646 *) caching should now work on subrequests (still very experimental)
2649 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2651 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2654 *) Refactor ap_rgetline so that it does not use an internal brigade.
2655 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2657 *) Remove mod_auth_db. [Justin Erenkrantz]
2659 *) Do not install unnecessary pcre headers like config.h and internal.h.
2660 [Joe Orton <joe manyfish.co.uk>]
2662 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
2663 (as it does for a normal request). quick_handled sub-requests now work
2664 in mod-include [Ian Holsman]
2666 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
2667 'CONTENT' one, as it needs to run AFTER all content headers
2669 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
2672 *) Split out blocking from the mode in the input filters.
2675 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
2677 *) Cause Win32 to capture all child-worker process errors in
2678 Apache to the main server error log, until the child can
2679 open its own error logs. [William Rowe]
2681 *) HPUX 11.*: Do not kill the child process when accept()
2682 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
2683 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
2685 *) Fix a problem in the parsing of the <Proxy foo> directive.
2688 *) rewrite of mod_ssl input filter for better performance and less
2689 memory usage [Doug MacEachern]
2691 *) allow quick_handler to be run on subrequests. [Ian Holsman]
2693 *) mod_dav now asks its provider to place content directly into the
2694 filter stack when handling a GET request. The mod_dav/provider
2695 API has changed, so providers need to be updated. [Greg Stein]
2697 *) Clear the output socket descriptor in unixd_accept() to make sure
2698 we don't supply a bogus socket to the caller if the accept fails.
2699 This caused problems with the worker MPM, which tried to process
2700 the returned socket if it was non-NULL. [Brian Pane]
2702 *) Move a check for an empty brigade to the start of core input filter
2703 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
2705 *) Add FileETag directive to allow configurable control of what
2706 data are used to form ETag values for file-based URIs. MMN
2707 bumped to 20020111 because of fields added to the end of
2708 the core_dir_config structure. [Ken Coar]
2710 *) Fix a segfault in mod_rewrite's logging code caused by passing the
2711 wrong config to ap_get_remote_host(). [Jeff Trawick]
2713 *) Allow mod_cgid to work from a binary distribution install by
2714 using 755 for the permissions on the log directory instead of
2717 *) Fixed a segfault that happened during graceful shutdown (or when
2718 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
2720 *) Split all Win32 modules [excluding the core components mod_core,
2721 mod_so, mod_win32 and the winnt mpm] into individual loadable
2722 modules, so the administrator may individually disable the former
2723 compiled-in modules by simply commenting out their LoadModule
2724 directives. [William Rowe]
2726 *) Saved Win32 module authors and porters many future headaches, by
2727 duplicating the appropriate .h files such as os.h into the include
2728 directory, including in the build tree. [William Rowe]
2730 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
2731 Use SSL functions/macros instead of directly dereferencing SSL
2732 structures wherever possible.
2733 Add type-casts for the cases where functions return a generic pointer.
2734 Add $SSL/include to configure search path.
2735 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
2737 *) Moved several pointers out of the shared Scoreboard so it is
2738 more portable, and will present the vhost name across server
2739 generation restarts. [William Rowe]
2741 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
2744 Changes with Apache 2.0.30
2746 *) Fix the main bug for FreeBSD and threaded MPM's. There are
2747 still issues (see STATUS) but at least the server will now
2748 run without crashing the machine.
2749 [David Reid, Aaron Bannert, Justin Erenkrantz]
2751 *) Fix a typo in mod_deflate's m4 config section.
2752 [albert chin <china thewrittenword.com>]
2754 *) Fix a couple of mod_proxy problems forwarding HTTP connections
2755 and handling CONNECT:
2756 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
2757 (2) Proxy failed to connect when the first IP address returned by
2758 the resolver was unreachable but a secondary IP address was.
2761 *) Fix the module identifer as shown in the docs for various core
2762 modules (e.g., the identifer for mod_log_config was previously
2763 listed as config_log_module). PR #9338
2764 [James Watson <ap2bug sowega.org>]
2766 *) Fix LimitRequestBody directive by placing it in the HTTP
2767 filter. [Justin Erenkrantz]
2769 *) Fix mod_proxy seg fault when the proxied server returns
2770 an HTTP/0.9 response or a bogus status line.
2773 *) Prevent mod_proxy from truncating one character off the
2774 end of the status line returned from the proxied server.
2775 [Adam Sussman, Bill Stoddard]
2777 *) Eliminate loop in ap_proxy_string_read().
2778 [Adam Sussman, Bill Stoddard]
2780 *) Provide $0..$9 results from mod_include regex parsing.
2783 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
2785 *) Introduced the ForceLanguagePriority directive, to prevent
2786 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
2787 when using Multiviews. [William Rowe]
2789 *) Fix a problem which prevented mod_cgid and suexec from working
2790 together reliably [Greg Ames]
2792 *) Remove the call to exit() from within mod_auth_digest's post_config
2793 phase. [Aaron Bannert]
2795 *) Fix a problem in mod_auth_digest that could potentially cause
2796 problems with initialized static data on a system that uses DSOs.
2799 *) Fix a segfault in the worker MPM that could happen during
2800 child process exits. [Brian Pane, Aaron Bannert]
2802 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
2804 *) Fix matching of vhosts by ip address so we find IPv4
2805 vhost address when target address is v4-mapped form of
2806 that address. [Jeff Trawick]
2808 *) More performance tweaks to the BNDM string-search algorithm
2809 used to find "<!--#" tokens in mod_include [Brian Pane]
2811 *) Miscellaneous small performance fixes: optimized away various
2812 string copy operations and removed large temp buffers from
2813 the stack [Brian Pane]
2815 *) Fixed startup segfault that occurred when a VirtualHost
2816 directive had a port but no address [Brian Pane]
2818 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
2820 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
2821 if oslevel < WINNT. This should fix several problems reported
2822 Against 2.0.28 on Windows 98 [Bill Stoddard]
2824 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
2825 to fail. [Bill Stoddard]
2827 *) Change core code to allow an MPM to set hard thread/server
2828 limits at startup. prefork, worker, and perchild MPMs now have
2829 directives to set these limits. [Jeff Trawick]
2831 *) Win32: The async AcceptEx() event should be autoreset upon
2832 successful completion of a wait (WaitForSingleObject). This
2833 eliminates a number of spurious
2834 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
2837 *) Move any load library path environment variables out of
2838 apachectl and into a separate environment variable file which
2839 can be more easily tailored by the admin. The environment
2840 variable file as built by Apache may have additional system-
2841 specific settings. For example, on OS/390 we tailor the heap
2842 settings to allow lots of threads. [Jeff Trawick]
2844 *) Use the new APR pool code to reduce pool-related lock
2845 contention in the worker MPM. [Sander Striker]
2847 *) The POD no longer assumes the child is listening on 127.0.0.1
2848 and now pulls the first hostname in the list of listeners to
2849 perform the dummy connect on. This fixes a bug when the user
2850 had configured the Listen directive for an IP other than
2851 127.0.0.1. This would result in undead children and error
2852 messages such as "Connection refused: connect to listener".
2855 *) The worker MPM now respects the LockFile setting, needed to
2856 avoid locking problems with NFS. [Jeff Trawick]
2858 *) Fix segfault when worker MPM receives SIGHUP.
2859 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
2861 *) Fix bug that could potentially prevent the perchild MPM from
2862 working with more than one vhost/uid. [Aaron Bannert]
2864 *) Change make install and apxs -i processing of DSO modules to
2865 perform special handling on platforms where libtool doesn't install
2866 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
2867 which prevented standard LoadModule statements from working.
2870 *) Whenever mod_so is enabled (not just when there are DSOs for
2871 our modules), do whatever special magic is required for compiling/
2872 loading third-party modules. This allows third-party DSOs to
2873 be used on an AIX build when there were no built-in modules
2874 built as DSOs. (This should help on OS/390 and BeOS as well.)
2877 *) Allow apxs to be used to build DSOs on AIX without requiring the
2878 user to hard-code the list of import files. (This should help
2879 on OS/390 and BeOS as well.) [Jeff Trawick]
2881 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
2882 PR 8563, 8919 [William Rowe]
2884 *) Get binary builds working when libapr and libaprutil are built
2887 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
2888 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
2889 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
2891 *) Fix the handling of SSI directives in which the ">" of the
2892 terminating "-->" is the last byte in a file [Brian Pane]
2894 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
2895 message that we had back in apache-1.3 and still have scattered
2896 throughout our docs. [Aaron Bannert]
2898 *) Prevent the Win32 port from continuing after encountering an
2899 error in the command line args to apache. [William Rowe]
2901 *) On a error in the proxy, make it write a line to the error log
2904 *) Various mod_ssl performance improvements [Doug MacEachern]
2906 Changes with Apache 2.0.29
2908 *) Add buffering in core_output_filter to ensure that long
2909 lists of small buckets don't cause small packet writes.
2910 [Brian Pane, Ryan Bloom]
2912 *) Fix the installation target to make sure that the manual is
2913 installed in the correct location.
2914 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
2915 Gomez Henri <hgomez slib.fr>]
2917 *) Fix the cmd command for mod_include. When we are processing
2918 a cmd command, we do not want to use the r->filename to set
2919 the command name. The command comes from the SSI tag. To do this,
2920 I added a variable to the function that builds the command line
2921 in mod_cgi. This allows the include_cmd function to specify
2922 the command line itself. [Ryan Bloom]
2924 *) Change open_logs hook to return a value, allowing you
2925 to flag a error while opening logs
2926 [Ian Holsman, Doug MacEachern]
2928 *) Change post_config hook to return a value, allowing you
2929 to flag a error post config
2930 [Ian Holsman, Jeff Trawick]
2932 *) Allow SUEXEC_BIN (the path to the suexec binary that is
2933 hard-coded into the server) to be specified to the configure
2934 script by the --with-suexec-bin parameter. [Aaron Bannert]
2936 *) Fix segv in worker MPM following accept on pipe-of-death
2939 *) Add mod_deflate to experimental.
2940 [Ian Holsman, Justin Erenkrantz]
2942 *) Bail out at configure time if an invalid MPM was specified.
2943 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
2945 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
2946 configured [John Sterling <sterling covalent.net>]
2948 *) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>]
2950 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
2952 *) Optimization for the BNDM string-search function in
2953 mod_include. [Brian Pane]
2955 *) Fixed the behavior of the XBitHack directive.
2956 [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
2958 *) The threaded MPM for Unix has been removed. Use the worker
2959 MPM instead. [various]
2961 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
2962 in logging the error from a failed DNS lookup. [Jeff Trawick]
2964 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
2967 *) Get mod_cgid killed when a MPM exits due to a fatal error.
2970 *) Fix a file descriptor leak in mod_include. When we include a
2971 file, we use a sub-request, but we didn't destroy the sub-request
2972 immediately, instead we waited until the original request was
2973 done. This patch closes the sub-request as soon as the data is
2974 done being generated. [Brian Pane <bpane pacbell.net>]
2976 *) Allow modules that add sockets to the ap_listeners list to
2977 define the function that should be used to accept on that
2978 socket. Each MPM can define their own function to use for
2979 the accept function with the MPM_ACCEPT_FUNC macro. This
2980 also abstracts out all of the Unix accept error handling
2981 logic, which has become out of synch across Unix MPMs.
2984 *) Fix a bug which would cause the response headers to be omitted
2985 when sending a negotiated ErrorDocument because the required
2986 filters were attached to the wrong request_rec.
2987 [John Sterling <sterling covalent.net>]
2989 *) Remove commas from the end of the macros that define
2990 directives that are used by MPMs. Prior to this patch,
2991 you would use these macros without commas, which was unlike
2992 the macros for any other directives. Now, the caller provides
2993 the comma rather than the macro providing it. This makes
2994 the macros look more like the rest of the directives.
2995 [Ryan Bloom and Cliff Woolley]
2997 *) Add 'redirect-carefully' environment option to disable sending
2998 redirects under special circumstances. This is helpful for
2999 Microsoft's WebFolders when accessing a directory resource via
3000 DAV methods. [Justin Erenkrantz]
3002 *) Begin to abstract out the underlying transport layer.
3003 The first step is to remove the socket from the conn_rec,
3004 the server now lives in a context that is passed to the
3005 core's input and output filters. This forces us to be very
3006 careful when adding calls that use the socket directly,
3007 because the socket isn't available in most locations.
3010 *) Really reset the MaxClients value in worker and threaded
3011 when the configured value is not a multiple of the number
3012 of threads per child. We said we did previously but we
3013 forgot to. [Jeff Trawick]
3015 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
3017 *) If shared modules are requested and mod_so is not available,
3018 produce a fatal config-time error. [Justin Erenkrantz]
3020 *) Improve http2env's performance by cutting the work it has to
3021 do. [Brian Pane <bpane pacbell.net>]
3023 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
3024 [Brian Pane <bpane pacbell.net>]
3026 Changes with Apache 2.0.28
3028 *) Fix infinite loop in mod_cgid.c.
3029 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
3031 *) When no port is given in a "ServerName host" directive, the
3032 server_rec->port is now set to zero, not 80. That allows for
3033 run-time deduction of the correct server port (depending on
3034 SSL/plain, and depending also on the current setting of
3035 UseCanonicalName). This change makes redirections
3036 work, even with https:// connections. As in Apache-1.3, the
3037 connection's actual port number is never used, only the ServerName
3038 setting or the client's Host: setting. Documentation updated
3039 to reflect the change. [Martin Kraemer]
3041 *) Add a '%{note-name}e' argument to mod-headers, which works in
3042 the same way as mod_log_confg. [Ian Holsman]
3044 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
3045 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
3046 MPMs. [Cliff Woolley]
3048 *) Introduce htdbm, a user management utility for db/dbm authorization
3049 databases. [Mladen Turk <mturk mappingsoft.com>]
3051 *) Optimize usage of strlen and strcat in ap_directory_walk.
3052 [Brian Pane <bpane pacbell.net>]
3054 Changes with Apache 2.0.27
3056 *) Introduce an Apache mod_ssl initial configuration template
3057 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
3059 *) Fixed a memory leak in the getline parsing code that could
3060 be triggered by arbitrarily large header lines. Requests
3061 from the core input filter for single lines are now limited
3062 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
3064 *) Fix a truncation bug in how we print the port on the Via: header.
3065 The routine that prints the Via: header now takes a length for
3066 the port string. [Zvi Har'El <rl math.technion.ac.il>]
3068 *) Some syntax errors in mod_mime_magic's magic file can result
3069 in a 500 error, which previously was unlogged. Now we log the
3070 error. [Jeff Trawick]
3072 *) Add the support/checkgid helper app, which checks the run-time
3073 validity of group identifiers usable in the Group directive.
3076 *) Various --enable-so options have been fixed: --enable-so is
3077 treated as "static"; explicit --enable-so=shared issues an error;
3078 and explicit --enable-so fails with error on systems without
3079 APR_HAS_DSO. [Aaron Bannert]
3081 *) Fix a segfault in the core input filter when the client socket
3082 gets disconnected unexpectedly. [Cliff Woolley]
3084 *) Fix the reporting for child processes that die. This removes
3085 all of the non-portable W* macros from Apache.
3086 [Jeff Trawick and Ryan Bloom]
3088 *) Win32: Track and display "Parent Server Generation:" in
3089 mod_status output. The generation will be bumped at
3090 server graceful restart, when the child process exits
3091 by hitting MaxRequestsPerChild or if the child
3092 process exits abnormally. [Bill Stoddard]
3094 *) Win32: Fix problem where MaxRequestsPerChild directive was
3095 not being picked up in favor of the default. Enable
3096 the parent to start up a new child process immediately upon
3097 the old child starting shutdown.
3100 *) Fix some bungling of the remote port in rfc1413.c so that
3101 IdentityCheck retrieves the proper user id instead of failing
3102 and thus always returning "nobody."
3103 [Dick Streefland <Dick.Streefland xs4all.nl>]
3105 *) Introduced thread saftey for mod_rewrite's internal cache.
3106 [Brian Pane <bpane pacbell.net>]
3108 *) Simplified mod_env's directives to behave as most directives are
3109 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
3110 directive following that UnsetEnv within the same container.
3111 Also provides a runtime startup warning if a PassEnv configured
3112 environment value is undefined. [William Rowe]
3114 *) The worker MPM is now completely ported to APR's new lock API. It
3115 uses native APR types for thread mutexes, cross-process mutexes,
3116 and condition variables. [Aaron Bannert]
3118 *) Sync up documentation to remove all references to the now deprecated
3119 Port directive. [Justin Erenkrantz]
3121 *) Moved all ldap modules from the core to httpd-ldap sub-project
3124 *) Exit when we can't listen on any of the configured ports. This
3125 is the same behavior as 1.3, and it avoids having the MPMs to
3126 deal with bogus ap_listen_rec structures. [Jeff Trawick]
3128 *) Cleanup the proxy code that creates a request to the origin
3129 server. This change adds an optional hook, which allows modules
3130 to gain control while the request is created if the proxy module
3131 is loaded. The purpose of this hook is to allow modules to add
3132 input and/or output filters to the request to the origin. While
3133 I was at it, I made the core use this hook, so that proxy request
3134 creation uses some of the code from the core. This can still be
3135 greatly improved, but this is a good start. [Ryan Bloom]
3137 Changes with Apache 2.0.26
3139 *) Port the MaxClients changes from the worker MPM to the threaded
3142 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
3143 with the new input filtering system. [Justin Erenkrantz]
3145 *) Introduce the MultiviewsMatch directive, to allow the operator
3146 to be flexible in recognizing Handlers and Filters filename
3147 extensions as part of the Multiviews matching logic, strict with
3148 MultiviewsMatch NegotiatedOnly to accept only filename extentions
3149 that designate negotiated parameters, (content type, charset, etc.)
3150 or MultiviewsAll for the 1.3 behavior of matching any files, even
3151 if they have unregistered extensions. [William Rowe]
3153 *) Fixed the configure script to add a LoadModule directive to
3154 the default httpd.conf for any module that was compiled
3155 as a DSO. [Aaron Bannert <aaron clove.org>]
3157 *) rewrite mod_ssl input filtering to work with the new input filtering
3158 system. [Justin Erenkrantz]
3160 *) prefork: Don't segfault when we are able to listen on some but
3161 not all of the configured ports. [Jeff Trawick]
3163 *) Build mod_so even if no core modules are built shared.
3164 [Aaron Bannert <aaron clove.org>]
3166 *) Introduce ap_directory_walk rewrite (with further optimizations
3167 required) to adapt to the ap_process_request_internal() changes.
3168 Optimized so subrequests and redirects now reuse previous section
3169 merges, until we mismatch with the original directory_walk, and
3170 precomputed r->finfo results will cause directory_walk to skip
3171 the most expensive phases of the function. [William Rowe]
3173 *) Allow ApacheMonitor to connect to and control Apache on other
3174 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
3176 *) Remove the Port directive. In it's place, the Listen directive
3177 is now a required directive, which tells Apache what port to
3178 listen on. The ServerName directive has also been extended
3179 to accept an optional port. If the port is specified to the
3180 ServerName, the server will report that port whenever it
3181 reports the port that it is listening on. This change was
3182 made to ease configuration errors that stem from having a Port
3183 directive, and a Listen directive. In that situation, the server
3184 would only listen to the port specified by the Listen command,
3185 which caused a lot of confusion to users. [Ryan Bloom]
3187 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
3188 build, as loadable modules. [William Rowe]
3190 *) Fix --enable-mods-shared processing. If most is specified,
3191 then all modules that can be compiled as shared modules are.
3192 [Aaron Bannert <aaron clove.org>]
3194 *) Update the mime.types file to map video/vnd.mpegurl to mxu
3195 and add commonly used audio/x-mpegurl for m3u extensions.
3196 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
3198 *) Eliminate the depreciated r->content_language, in favor of the array
3199 r->content_languages introduced many years ago. Module authors must
3200 substantially overhaul their modules, so this needs to be upgraded
3201 if the module still relied on backwards-brokeness. [William Rowe]
3203 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
3206 *) Rewrite the input filtering mechanisms to consolidate and reorganize
3207 code. In short, core_input_filter does something now and
3208 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
3210 *) Update the Win32 build to re-absorb mod_proxy and family.
3213 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
3214 current SDK.) [William Rowe]
3216 *) Some style changes to the code that does ProxyErrorOverride. Fixed
3217 config merge behaviour. [Graham Leggett]
3219 *) Allow support programs to be compiled against a static version
3220 of libapr. This allows the smaller support programs to be
3221 relocated. [Aaron Bannert <aaron clove.org>]
3223 *) Update the mime.types file to the registered media types as
3224 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
3226 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
3227 number of clients that can connect at the same time, instead of
3228 specifying the maximum number of child processes.
3229 [Aaron Bannert <aaron clove.org>]
3231 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
3232 be consistent with 1.3. [Justin Erenkrantz]
3234 *) Cache apr_explode_localtime() value for 15 seconds.
3235 [Brian Pane <bpane pacbell.net>]
3237 *) Fix mod_include to not return ETag or Last-Modified headers.
3238 [Ian Holsman <ianh cnet.com>]
3240 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
3242 *) Eliminate the wasteful run-time conversion of method names from strings
3243 to numbers in places where the methods are known at compile time.
3244 [Brian Pane <bpane pacbell.net>]
3246 *) Turn the worker MPM's queue into a LIFO. This may
3247 improve cache-hit performance under some conditions.
3248 [Aaron Bannert <aaron clove.org>]
3250 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
3251 support it. [Justin Erenkrantz]
3253 *) Cleanup the worker MPM. We no longer re-use transaction
3254 pools. This incurs less overhead than shuffling the pools
3255 around so that they can be re-used. Remove one of the
3256 queue's condition variables. We just redefined the API to
3257 state that you can't try to add more stuff than you allocated
3258 segments for. [Aaron Bannert <aaron clove.org>]
3260 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
3262 *) Fixed persistent connections when a request contains a body.
3265 *) mod_dav uses a new API to speak to the backend provider for dead
3266 property management. [Greg Stein]
3268 *) Remove the Win32 script-processing exception from mod_cgi, and
3269 roll build_command_line/build_argv_list into a unified, overrideable
3270 ap_cgi_build_command optional function. [William Rowe]
3272 *) Rewrite find_start_sequence to use a better search algorithm
3273 to find the start tag. [Justin Erenkrantz]
3275 *) Fix a seg fault in mod_include. When we are generating an
3276 internal redirect, we must set r->uri to "", not a bogus
3277 string, and not NULL. [Ryan Bloom]
3279 *) Optimized location_walk, so subrequests, redirects and second passes
3280 now reuse previous section merges on a <Location > by <Location >
3281 basis, until we mismatch with the original location_walk.
3284 *) Back out the 1.45 change to util_script.c. This change made
3285 us set the environment variable REQUEST_URI to the redirected
3286 URI, instead of the originally requested URI.
3287 [Taketo Kabe <kabe sra-tohoku.co.jp>]
3289 *) Make mod_include do lazy evaluation of potentially expensive to
3290 compute variables. [Brian Pane <bpane pacbell.net>]
3292 *) Fix logging of bytes sent for HEAD requests. %b and %B should
3293 log either - or 0, before this patch, they were both logging
3294 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
3296 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
3297 than per character. [Brian Pane <bpane pacbell.net>]
3299 *) Normalize the primary request, redirects and sub-requests to
3300 run the same ap_process_request_internal for consistency in
3301 robustness, behavior and security. [William Rowe]
3303 *) Fix a segfault with mod_include when r->path_info is not set
3304 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
3306 *) Add -X functionality back. This indicates to all MPMs and any other
3307 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
3309 *) Some initial support for the cygwin platform [prefork only].
3310 This is not to be confused with support for the WinNT/Win32
3311 platform, which is the recommended configuration for native
3312 Win32 users. The cygwin platform support is recommended for
3313 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
3315 *) Changed syntax of Set{Input|Output}Filter. The list of filters
3316 must be semicolon delimited (if more than one filter is given.)
3317 The Set{Input|Output}Filter directive now overrides a parent
3318 container's directive (e.g. SetInputFilter in <Directory /web/foo>
3319 will override any SetInputFilter directive in <Directory /web>.)
3320 This new syntax is more consistent with Add{Input|Output}Filter
3321 directives defined in mod_mime. Also cures a bug in prior releases
3322 where the Set{Input|Output}Filter directive would corrupt the
3323 global configuration if the multiple directives were nested.
3326 *) Cured what's ailed mime for quite some time. If an AddSomething
3327 was given in the configuration (Language, Charset, Handler or
3328 Encoding) Apache would set the content type as given by AddType,
3329 but refused to check the mime.types file if AddType wasn't given
3330 for that specific extension. Setting the AddHandler for .html
3331 without setting the AddType text/html html would cause Apache to
3332 use the default content type. [William Rowe]
3334 *) Added some bulletproofing to memory allocation in the LDAP cache
3335 code. [Graham Leggett]
3337 Changes with Apache 2.0.25
3339 *) Move the installed /manual directory out of the /htdocs/ tree, so
3340 that it can be kept more independently from the remaining document
3341 root. The "Alias /manual ..." already allowed for easy projection
3342 into existing private document trees. [Martin Kraemer]
3344 *) Add specified user attributes to the environment when using
3345 mod_auth_ldap. This allows you to use mod_include to embed specified
3346 user attributes in a page like so:
3347 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
3350 *) Fix a performance problem with the worker MPM. We now create
3351 transaction pools once, and re-use them for each connection.
3352 [Aaron Bannert <aaron clove.org>]
3354 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
3355 of a 'handler' or 'filter', so that any filename extension that does
3356 not contribute to the negotiated metadata can't be served without
3357 an explicit request. E.g., if the .Z extension is associated with
3358 an unzip filter, the user request somefile.Z.html, mod_negotiation
3359 won't serve it. It can serve somefile.Z.html when somefile.Z is
3360 requested, since the .Z extension is explictly requested, if the
3361 .html extension is associated with ContentType text/html.
3364 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
3365 and corresponding AddOutputFilter syntax, to insert one or more
3366 filters by mod_mime filename extension processing.
3369 *) Fix a growing connection pool in core_output_filter() for
3370 keepalive requests. [Jeff Trawick]
3372 *) Moved split_and_pass_pretag_buckets back to being a
3373 macro at Ryans's request. Removed the return from it
3374 by setting and returning a return code instead. Updated
3375 the code to check the return code from the macro and
3376 do the right thing. [Paul J. Reder]
3378 *) Fix a segfault when a numeric value was received for Host:.
3381 *) Add a function ap_remove_input_filter. This is to match
3382 up with ap_remove_output_filter. [Ryan Bloom]
3384 *) Clean up location_walk, so that this step performs a minimum
3385 amount of redundant effort (it must be run twice, but it will no
3386 longer reparse all <Location > blocks when the request uri
3387 hadn't changed.) [William Rowe]
3389 *) Eliminate proxy: (and all other 'special') processing from the
3390 ap_directory_walk() phase. Modules that want to use special
3391 walk logic should refer to the mod_proxy map_to_location example,
3392 with it's proxy_walk and proxysection implementation. This makes
3393 either directory_walk flavor much more legible, since that phase
3394 only runs against real <Directory > blocks.
3397 *) SECURITY: Fix a security problem in mod_include which would allow
3398 an SSI document to be passed to the client unparsed.
3399 [Cliff Woolley, Brian Pane]
3401 *) Introduce the map_to_storage hook, which allows modules to bypass
3402 the directory_walk and file_walk for non-file requests. TRACE
3403 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
3404 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
3407 *) Add the ability for mod_include to add the INCLUDES filter
3408 if the file is configured for the server-parsed handler.
3409 This makes the configuration for .shtml files much easier
3410 to understand, and allows mod_include to honor Apache 1.3
3411 config files. Based on Doug MacEachern's patch to PHP
3412 to do the same thing. [Ryan Bloom]
3414 *) force OpenSSL to ignore process local-caching and to always
3415 get/set/delete sessions using mod_ssl's callbacks
3416 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3417 Geoff Thorpe <geoff geoffthorpe.net>]
3419 *) Make the worker MPM shutdown and restart cleanly. This also
3420 cleans up some race conditions, and gets the worker using
3421 pools more cleanly. [Aaron Bannert <aaron clove.org>]
3423 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
3425 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3427 *) Fix for mod_include. Ryan's patch to check error
3428 codes put a return in the wrong place. Also, the
3429 include handler return code wasn't being checked.
3430 I don't like macros with returns, so I converted
3431 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
3432 [Paul J. Reder <rederpj raleigh.ibm.com>]
3434 *) fix segv in mod_mime if no AddTypes are configured
3435 [John Sterling <sterling covalent.net>]
3437 *) Enable ssl client authentication at SSL_accept time
3438 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3440 *) Fix a segfault in mod_include when the original request has no
3441 associated filename (e.g., we're filtering the error document for
3442 a bad URI). [Jeff Trawick]
3444 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
3446 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
3447 of httpd is started and shuts down due to socket conflict. Moving the
3448 call to ap_log_pid solves the problem.
3450 *) Changed the late-1.3 log_config substitution %c to %X, to log the
3451 status of the closed connection, as it conflicts with the far more
3452 common, historical ssl logging directive %...{var}c. [William Rowe]
3454 *) Added the common error/ tree to the build/install targets
3455 (similar to the common icons/ tree) for the multi-language error
3456 messages that Lars committed earlier. [William Rowe]
3458 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
3460 *) Added a default commented-out mod_ldap and mod_auth_ldap
3461 configuration to httpd-std.conf and httpd-win.conf
3464 *) Added documentation for mod_ldap and mod_auth_ldap.
3467 *) Enabled negative caching on attribute comparisons in the LDAP cache.
3468 Fixed a problem where the default cache TTL was set in milliseconds
3469 not microseconds causing the cache to time out almost immediately.
3472 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
3473 module code to follow APR. [Graham Leggett]
3475 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
3476 cleaned up when the connection pool pool is cleaned up.
3479 *) Fix a minor issue with Jeff Trawick's mod_include
3480 patch. Without this patch, the code will just allocate
3481 more bytes in get_combined_directive than are needed.
3484 *) Added the LDAP authentication module mod_auth_ldap.
3485 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3487 *) Added the LDAP cache and connection pooling module mod_ldap.
3488 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3490 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
3491 by allowing a module to disable itself if its prerequisites are not
3492 met. [Justin Erenkrantz]
3494 Changes with Apache 2.0.24
3496 *) Fix a couple of issues in mod_include when the tag appeared at
3497 offsets near 8192 in the file being parsed. [Jeff Trawick]
3499 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
3500 reached. [Jeff Trawick]
3502 *) Numerous improvements to the Win32 build system. Introduced command line
3503 builds without requiring .mak files for MSVC 6.0 and later versions.
3504 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
3507 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
3508 reporting of uninstalled services and other error conditions, and changed the
3509 default service name to Apache2. [William Rowe]
3511 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
3512 compatibility with existing Apache 1.3 Win32 Apache management utilites.
3513 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
3515 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
3516 [William Rowe, Greg Ames]
3518 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
3519 and RemoveCharset directives. [William Rowe]
3521 *) The Unix MPMs other than perchild now allow child server
3522 processes to use the accept mutex when starting as root and
3523 using SysV sems for the accept mutex. Previously, this
3524 combination would lead to fatal errors in the child server
3525 processes. perchild can't use SysV sems because of security
3526 issues. [Jeff Trawick, Greg Ames]
3528 *) Added Win32 revision stamp resources to all http binaries
3529 (including modules/ and support/ tools.) PR7322 [William Rowe]
3531 *) Fix ap_rvprintf to support more than 4K of data at one time.
3532 [Cody Sherr <csherr covalent.net>]
3534 *) We have always used the obsolete/deprecated Netscape syntax
3535 for our tracking cookies; now the CookieStyle directive
3536 allows the Webmaster to choose the Netscape, RFC2109, or
3537 RFC2965 format. The new CookieDomain directive allows the
3538 setting of the cookie's Domain= attribute, too. PR #s 5006,
3539 5023, 5920, 6140 [Ken Coar]
3541 *) Tweak server/Makefile so that the rules for generating exports.c
3542 are compatible with make utilities which don't expand wildcards
3543 in a dependency list (e.g., OS/390 make, certain levels of GNU
3544 make). [Jeff Trawick]
3546 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
3548 *) Begin to sanitize the MPM configuration directives. Now, all
3549 MPMs use the same functions for all common MPM directives. This
3550 should make it easier to catch all bugs in these directives once.
3551 [Cody Sherr <csherr covalent.net>]
3553 *) Close a major resource leak. Every time we had issued a
3554 graceful restart, we leaked a socket descriptor.
3557 *) Fix a problem with the new method code. We need to cast
3558 the 1 to an apr_int64_t or it will be treated as a 32-bit
3559 integer, and it will wrap after being shifted 32 times.
3560 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
3562 *) Fix a bug in mod_expires. Previous to this patch, if you
3563 told mod_expires to add 604800 seconds to the last-modified
3564 time, it actually added 604800 usec's to the last-modified time,
3565 so that when looking at the response it looked like nothing
3566 had been done. The root of the problem was that we always compute
3567 time in usec's, but we ask users to input sec's. This means we
3568 need to convert to usec's before using those values.
3571 *) The worker MPM now handles shutdown and restart requests. It
3572 definitely isn't perfect, but we do stop the servers correctly.
3573 The biggest problem right now is that SIGHUP causes the server to
3574 just die. [Ryan Bloom]
3576 Changes with Apache 2.0.23
3578 *) Use the prefork MPM by default on Unix. [various]
3580 *) Added a systray icon monitor application for Win32.
3581 [Mladen Turk <mturk mappingsoft.com>]
3583 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3584 messages written to the rewrite log.
3585 [Richard Labennett <rlabenn us.ibm.com>]
3587 *) All mod_autoindex query parsing is now quietly quashed with the
3588 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3589 still drops the column sort <a href>'s for the column headers, but
3590 IgnoreClient is required to ignore these Query options entirely.
3593 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3594 to allow the client to select plain, FancyIndexing or HTMLTable
3595 formatting, V=[0|1] to inhibit or enable version sorting, and
3596 P=pattern to return only specific files. The old Query Arguments
3597 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3598 as before), and O=A|D for ordering ascending or descending.
3601 *) Fixed an error in mod_include's directive parsing routines which
3602 caused #if, #elif, and #else expressions containing backslashes
3603 to be improperly evaluated. [Cliff Woolley]
3605 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3606 drop the icon column, SuppressRules to drop the <hr> elements,
3607 and HTMLTable to create rudimentary HTML table listings (implies
3608 FancyIndexing). [William Rowe]
3610 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3611 from Apache 1.3.15. This is needed for two reasons, first, given
3612 multiple machines within a server farm, ETags and Last-Modified
3613 stamps won't correspond from machine to machine, and second, many
3614 Unixes don't capture changes to the date or time stamp of existing
3615 files, since these don't modify the dirent itself. [William Rowe]
3617 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3618 and DirectoryWidth options from Apache 1.3.10.
3619 [William Rowe, Ken Coar]
3621 *) Eliminated FancyIndexing directive, deprecated early in Apache
3622 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3624 *) mod_autoindex now excludes any file names that would result in
3625 an error, other than a success or redirect. Also optimized
3626 the parent directory, always included except in the URI '/'.
3629 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3630 negotiated index pages, and prevent the server from defaulting
3631 to an autoindex of the directory. mod_negotiation will now die
3632 with a 500 Internal Error if it could match some filenames
3633 (e.g. for mod_dir) but none can be served. mod_negotation now
3634 refuses to serve any file with an extention that mod_mime doesn't
3635 recognize, and wasn't part of the request. [William Rowe]
3637 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3638 extension. This is already handled by multiviews, if the admin
3639 wishes to AddHandler .exe or define a content type handler and
3640 associate .exe files with that content type. Multiviews must be
3641 enabled to allow these to be served. [William Rowe]
3643 *) Speed up the server's response to a spike in incoming workload
3644 or restarts by assigning empty scoreboard slots to new processes
3645 when they are available. [Greg Ames]
3647 *) Add a handler to mod_includes.c. This handler is designed to
3648 implement the XbitHack directive. This can't be done with a
3649 fixup, because we need to check the content-type, which is
3650 only available in the handler phase. [Ryan Bloom]
3652 *) Make the includes filter check return codes from filters lower in
3653 the filter chain. If a lower level filter returns an error, then
3654 the request needs to stop immediately. This allows mod_include to
3655 stop parsing data once a lower filter recognizes an error.
3658 *) Add the ability to extend the methods that Apache understands
3659 and have those methods <limit>able in the httpd.conf. It uses
3660 the same bit mask/shifted offset as the original HTTP methods
3661 such as M_GET or M_POST, but expands the total bits from an int to
3662 an ap_int64_t to handle more bits for new request methods than
3663 an int provides. [Cody Sherr <csherr covalent.net>]
3665 *) Fix broken mod_mime behavior in merging its arguments. Possible
3666 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
3668 *) Solve many mod_ssl porting issues (too many to detail) with
3669 help from the whole team, but most notably [Ralf S. Engelschall,
3670 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3671 Doug MacEachern, William Rowe, Cliff Woolley]
3673 *) More stall fixes for the threaded & worker mpm's.
3674 Make mod_status output more accurate. Don't
3675 count workers in processes which aren't actively
3676 serving requests. [Greg Ames]
3678 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
3680 *) Add a single listener/multiple worker MPM. This MPM is
3681 definately not fully correct, but it allows us to solve many
3682 of the problems that exist in the threaded MPM. This is a
3683 modified version of the threaded MPM. [Ryan Bloom]
3685 *) Improve content generation throughout Apache, providing closer
3686 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
3687 Transitional specifications. [William Rowe]
3689 Changes with Apache 2.0.22
3691 *) Fix a problem where the threaded MPM stalls after restarts or
3692 segfaults. Also prevent multiple active processes from using
3693 the same scoreboard slot. [Greg Ames]
3695 *) Apache/Win32 now fills in the service description with Apache's
3696 server version string, including loaded and advertised modules.
3699 *) Improved support for the Win32 build, to recover gracefully from
3700 missing apr or apr-util directories or the awk interpreter,
3701 create the proper cgi-bin examples, including a test-cgi.bat, and
3702 fix the perl shebang line for printenv.pl, when installing from
3703 the build environment. [William Rowe]
3705 *) Fix a segfault in threaded.c caused by passing uninitialized
3706 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
3708 *) Use new APR number conversion functions to reduce CPU consumption
3709 when setting the content length, and in mod_log_config.
3712 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
3713 where HEAD response headers were being repeated twice for
3714 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
3715 problem in the http_header filter was exposed by the recent rewrite
3716 of the content_length filter. [Taketo Kabe, Bill Stoddard]
3718 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
3719 restarts. A garbage pointer to a vhost's server_rec from the
3720 previous generation was being left around under certain
3721 conditions. [Greg Ames]
3723 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
3724 used to appear as '(none', without the closing paren.
3725 [Günter Knauf <eflash gmx.net>]
3727 *) Improve the exports generating awk script. In the past, we had
3728 work around problems in the awk script by avoiding some #if and
3729 #ifdefs. This has bitten us many times in generating the exports.c
3730 file. This improvement allows corrects the header file parsing.
3731 [Sander Striker <striker apache.org>]
3733 Changes with Apache 2.0.21
3735 *) Resolve the Win32 htpasswd bug, where a file that existed would be
3736 overwritten, regardless of the -c flag.
3737 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
3739 *) Introduce connection sub-pools into ab. Truncating the lifetime
3740 of these allocations means that ab no longer perpetually grows
3741 its working set, running out of memory on large request attempts.
3744 *) Make scoreboard creation a hook. This allows management
3745 modules to have access to the scoreboard at the time that it is
3746 created, and at every restart request.
3747 [Cody Sherr <csherr covalent.net>]
3749 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
3750 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
3751 daemon index actually used in the scoreboard. I also
3752 updated the pertinent calls. [Paul J. Reder]
3754 *) Win32: Prevent listening sockets from being inherited by
3755 the Apache child process, CGI scripts, rotatelog process
3756 etc. If the Apache child process segfaults, any processes
3757 that the child started are not reaped. Prior to this fix,
3758 these processes inherited the listening sockets which sometimes
3759 prevented the restarted Apache child process from accepting
3760 connections (ie, the server would hang).
3763 *) Provide vhost and request strings when ExtendedStatus is on.
3766 *) Fix some issues with the pod and prefork: check the pod *after*
3767 processing a connection so that a server processing a time-
3768 consuming request bails out as soon as practical; when the
3769 parent process wakes up a server process via connect(), use an
3770 APR timeout on the connect() so that we don't hang for a long
3771 time if there aren't server processes around to do accept().
3772 [Jeff Trawick, Greg Ames]
3774 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
3775 spends a lot of time in apr_table_get calls. Using the default
3776 httpd.conf, the tables for languages and charsets are somewhat
3777 large, so the time spent scanning them on each request is
3778 significant. Replacing the tables with hash tables provides
3779 a nice speedup. [Brian Pane <bpane pacbell.net>]
3781 *) Add two functions to allow modules to access random parts of the
3782 scoreboard. This allows modules compiled for one MPM to access the
3783 scoreboard, even if it the server was compiled for another MPM.
3784 [Harrie Hazewinkel <harrie covalent.net>]
3786 Changes with Apache 2.0.20
3788 *) Fix problem in content-length filter where the filter would
3789 buffer all the output from a CGI before sending any bytes
3790 down the filter stack to the network. This problem would cause
3791 significant memory consumption if the CGIs generated
3792 lots of bytes. [Bill Stoddard]
3794 *) Get non-blocking CGI pipe reads working with the bucket brigades.
3797 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
3800 *) Fix a bug in the threaded MPM that would cause it to kill off all
3801 workers immediately after starting if the number of workers started
3802 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
3804 Changes with Apache 2.0.19
3806 *) Fix problem with threaded MPM. The problem was that if each child
3807 process was busy serving a single long-lived request and the server
3808 was sent a graceful restart signal, the server would stop serving
3809 requests. This would happen because each child process would wait to
3810 die until the last thread was done, and the parent wouldn't spawn any
3811 new children until a process died. Now, the parent looks at the fact
3812 that the children are dying gracefully, and starts new children.
3813 Those new children only start enough threads to compliment the number
3814 of threads in the other child process that shares the same spot in
3815 the scoreboard. In this way, we make sure to never go over
3816 MaxClients. [Ryan Bloom]
3818 *) modified mod_negotiation and mod_autoindex to speed up by almost a
3819 factor of two on apr_dir_read()-enhanced platforms, such as Win32
3820 and OS2, by calling ap_sub_request_lookup_dirent() with the results
3821 already provided by apr_dir_read(). [William Rowe]
3823 *) mod_file_cache is now more robust to filtering and serves requests
3824 slightly more efficiently. [Cliff Woolley]
3826 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
3827 Module was calling ap_rwrite() followed by ap_rflush() but the
3828 served content was not being displayed in the browser. Inspection
3829 of the output stream revealed that the first data chunk was
3830 missing the trailing CRLF required by the RFC. [Bill Stoddard]
3832 *) apxs no longer generates ap_send_http_header() in the example handler
3834 *) Fix an ab problem which could cause a divide-by-zero exception
3835 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
3836 [Ian Holsman <ianh cnet.com>]
3838 *) Solve case-insensitive platforms' confusion about negotiated
3839 filenames, allowing files of differnt case to match in choosing
3840 the document to serve. [William Rowe]
3842 *) Fix brokenness when ThreadsPerChild is higher than the built-in
3843 limit. We left ap_threads_per_child at the higher value which
3844 led to segfaults when doing certain scoreboard operations.
3847 *) Fix seg faults and/or missing output from mod_include. The
3848 default_handler was using the subrequest pool for files and
3849 MMAPs, even though the associated APR structures typically
3850 live longer than the subrequest. [Greg Ames]
3852 *) Extend mod_setenvif to support specifying regular expressions
3853 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
3854 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
3855 will cause HAVE_TS to be set if any of the request headers begins
3856 with "TS" and has a value that begins with any character in the
3857 set [a-z]. [Bill Stoddard]
3859 *) httpd children now re-bind themselves to a random CPU on
3860 multiprocessor systems on AIX via bindprocessor() in 2.0.
3861 [Victor J. Orlikowski]
3863 *) Fix htdigest. It would go into a loop in getline when adding
3864 a second user. [Bill Stoddard]
3866 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
3868 *) Automatically generate httpd.exp for AIX.
3869 DSOs now work again on AIX in 2.0
3870 [Victor J. Orlikowski]
3872 *) Add a new request hook, error_log. This phase allows modules
3873 to act on the error log string _after_ it has been written
3874 to the error log. The goal for this hook is to allow monitoring
3875 modules to send the error string to the monitoring agent.
3878 *) Modify mod_echo to make it use filters for input and output.
3879 [Ryan Morgan <rmorgan covalent.net>]
3881 *) Extend mod_headers to support conditional driven Header
3882 add, append and set. Use SetEnvIf to set an envar and conditionally
3883 add/append/set headers based on this envar thusly:
3885 SetEnvIf TSMyHeader value HAVE_TSMyHeader
3886 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
3888 If the request contains header "TSMyHeader: value" then header
3889 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
3892 *) Extend mod_headers to support using format specifiers on Header
3893 add, append and set header values. Two format specifiers are supported:
3895 %t - reports, in UTC microseconds since the epoch, when the
3896 request was received.
3898 %D - reports the time, in microseconds, between when the request was
3899 received and the response sent.
3902 Header add MyHeader "This request served in %D microseconds. %t"
3904 results in a header being added to the response that looks like this:
3906 MyHeader: This request served in D=5438 microseconds. t=991424704447256
3910 *) Fix reset_filter(). We need to be careful how we remove filters.
3911 If we set r->output_filters to NULL, we also have to reset the
3912 connection's filters. [John Sterling]
3914 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
3916 *) Add a check to ap_die() to make sure the filter stack is sane and
3917 contains the correct basic filters when an error occurs. This fixes
3918 a problem where headers are not being sent on error. [John Sterling]
3920 *) New Header directive 'echo' option. "Header echo regex" will
3921 cause any headers received on the request that match regex to be
3922 echoed to (included in) the response headers.
3925 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
3926 This prevented the inclusion of apr_compat.h. PR #7773
3927 [Oleg Broytmann <phd phd.pp.ru>]
3929 *) Moved util_uri to the apr-util library. This required a bunch of
3930 apr_name changes for the uri utility functions. [Justin Erenkrantz]
3932 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
3933 insert_filter phase so that other filters are not bypassed by default.
3936 *) Reimplement mod_headers as an output filter. mod_headers can now
3937 add custom headers to inbound requests using the RequestHeader directive
3938 and to responses using the same old Header directive. [Graham Leggett]
3940 Changes with Apache 2.0.18
3942 *) Fix command-line processing so that if a bad argument is specified
3943 Apache will exit. [Jeff Trawick]
3945 *) Change the make targets and rules to be consistent in all of the
3946 Apache-owned source trees. [Roy Fielding]
3948 *) Fix processing of the TRACE method. Previously we passed bogus
3949 parms to form_header_field() and it overlaid some vhost structures,
3950 resulting in a segfault in check_hostalias().
3951 [Greg Ames, Jeff Trawick]
3953 *) Win32: Add support for reliable piped logs. If the logging process
3954 goes down, Apache will automatically restart it. This function has
3955 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
3958 *) Do not start piped log processes during the config file
3959 preflight. This change also circumvents a problem on
3960 Windows where the rotatelog processes created during preflight
3961 was not getting cleaned up properly.
3964 *) add "Request Phase Participation" info to mod_info
3967 *) Make first phase changes to the scoreboard data structures in
3968 preparation for the rewriting of the scoreboard per my posted
3969 design notes. [Paul J. Reder]
3971 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
3972 and apr-util, allow it to be overridden by the configure command-line
3973 (default="--silent") and introduce LT_LDFLAGS to replace what we were
3974 formerly abusing as LTFLAGS. [Roy Fielding]
3976 *) Clean up the reporting of incorrect closing container tags.
3977 [Barrie Slaymaker <barries slaysys.com>]
3979 *) Simplify the configure process by moving all libtool stuff to APR
3980 and moving hints.m4 inline. [Roy Fielding]
3982 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
3983 of functions used by mod_proxy for export in the DLL
3984 [Ian Holsman <IanH cnet.com>]
3986 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
3987 request body from its stdin but no reqest body is being written to
3988 the cgi. [Jeff Trawick]
3990 *) mod_log_config: %c connection status incorrectly logged
3991 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
3994 *) Get mod_cern_meta working under Windows
3997 *) Create Files, and thus MMAPs, out of the request pool, not the
3998 connection pool. This solves a small resource leak that had us
3999 not closing files until a connection was closed. In order to do
4000 this, at the end of the core_output_filter, we loop through the
4001 brigade and convert any data we have into a single HEAP bucket
4002 that we know will survive clearing the request_rec.
4003 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
4006 *) Completely revamp configure so that it preserves the standard make
4007 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
4008 the configure additions to EXTRA_* variables. Also, allow the user
4009 to specify NOTEST_* values for all of the above, which eliminates the
4010 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
4011 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
4012 avoid pointless duplications. Fix the order in which flags are given
4013 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
4014 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
4015 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
4016 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
4018 *) Get mod_tls to compile/work better on Windows. PR #7612
4019 [Bernhard Schrenk <b.schrenk improx.com>]
4021 *) Fix shutdown/restart hangs in the threaded MPM.
4022 [Jeff Trawick, Greg Ames, Ryan Bloom]
4024 *) Removed the keptalive boolean from conn_rec because it is now only
4025 used by a single routine and can be replaced by a local variable.
4026 [Greg Stein, Ryan Bloom, Roy Fielding]
4028 *) Patch prefork to put enough of the signal processing back in so that
4029 signals are all handled properly now. The previous patch fixed the
4030 deadlock race condition, but broke the user directed signal handling.
4031 This fixes it to work the way it did before my previous prefork patch
4032 (primarily, SIGTERM is now working).
4034 *) Change how input filters decide how much data is returned to the
4035 higher filter. We used to use a field in the conn_rec, with this
4036 change, we use an argument to ap_get_brigade to determine how much
4037 data is retrieved. [Ryan Bloom]
4039 *) Fix seg fault at start-up introduced by Ryan's change to enable
4040 modules to specify their own logging tags. mod_log_config
4041 registers an optional function, ap_register_log_handler().
4042 ap_register_log_handler() was being called by http_core before
4043 the directive hash table was created. This patch creates the
4044 directive hash table before ap_register_log_handler() is
4045 registered as an optional function.
4046 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4048 *) Add ap_set_int_slot() function
4049 [John K. Sterling <sterling covalent.net>]
4051 *) Under certain circumstances, Apache did not supply the
4052 right response headers when requiring authentication.
4053 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
4054 (This is a port of the change that went into Apache 1.3.19.)
4056 *) Allow modules to specify their own logging tags. This basically
4057 allows a module to tell mod_log_config that when %x is encountered
4058 a specific function should be called. Currently, x can be any single
4059 character. It may be more useful to make this a string at some point.
4062 Changes with Apache 2.0.17
4064 *) If a higher-level filter handles the byterange aspects of a
4065 request, then the byterange filter should not try to redo the
4066 work. The most common case of this happening, is a byterange
4067 request going through the proxy, and the origin server handles
4068 the byterange request. The proxy should ignore it.
4069 [Graham Leggett <minfrin sharp.fm>]
4071 *) Changed the threaded mpm to have child_main join to each of the
4072 worker threads to make sure the kids are all gone before child_main
4073 exits after a signal (cleanup from perform_idle_server_maintenance).
4074 This is an extension of Ryans recent commit to make the child_main
4077 *) Add more options to the ap_mpm_query function. This also allows MPMs to
4078 report if their threads are dynamic or static. Finally, this also
4079 implements a new API, ap_show_mpm, which returns the MPM that was
4080 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
4082 *) Do not install the binaries from the support directory twice.
4083 [jun-ichiro hagino <itojun iijlab.net>]
4085 *) The ap_f* functions should flush data to the filter that is passed
4086 in, not the filter after the one passed in.
4087 [Ryan Morgan <rmorgan covalent.net>]
4089 *) Make ab work again by changing its native types to apr types and formats.
4090 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4092 *) Move the byterange filter and all of the supporting functions back
4093 to the HTTP module. The byterange filter turned out to be very
4094 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
4096 *) Make clean, distclean, and extraclean consistently according to the
4097 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4099 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
4100 This may have been causing problems stopping processes in the threaded
4103 *) Fix content-length in mod_negotiation to a long int representation.
4106 *) Remove BindAddress from the default config file.
4107 [<giles nemeton.com.au>]
4109 *) Allow module authors to add a module to their Apache build using
4110 --with-module, without re-running buildconf. The syntax is:
4111 --with-module=module_type:/path/to/module.c
4112 The configure script will copy the module.c file to
4113 modules/module_type, and it will be added to the relevant Makefiles.
4114 currently, this only works for static modules. [Ryan Bloom]
4116 *) Changes required to make prefork clean up idle children properly.
4117 There was a window during which a starting worker deadlocks when
4118 an idle cleanup arrives before it completes init. Apache then keeps
4119 trying to cleanup the same deadlocked worker forever (until higher
4120 pids come along, but it still will never reduce below the deadlocked
4121 pid). Thus the number of children would not reduce to the correct
4122 idle level. [Paul J. Reder]
4124 Changes with Apache 2.0.16
4126 *) Change the default installation directory to /usr/local/apache2,
4127 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
4129 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
4132 *) Get MaxRequestsPerChild working with the Windows MPM.
4135 *) Make generic hooks to work, with mod_generic_hook_import/export
4136 experimental modules. [Ben Laurie, Will Rowe]
4138 *) Fix segfaults for configuration file syntax errors such as
4139 "<Directory>" followed by "</Directory" and
4140 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
4142 *) Cleanup the --enable-layout option of configure. This makes
4143 us use a consistent location for the config.layout file, and it
4144 makes configure more portable.
4145 [jun-ichiro hagino <itojun iijlab.net>]
4147 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
4148 csv/gnuplot format, rudimentary ssl support and various other tweaks
4149 to make results more true to what is measured. The upshot of this it
4150 turns out that 'ab' has often underreported the true performance of
4151 apache. Often by a order of magnitude :-) See talk/paper of Sander
4152 Temme at April ApacheCon 2001 for details.
4153 [Dirk-Willem van Gulik]
4155 *) Clean up mod_cgid's temporary request pool. Besides fixing a
4156 storage leak this ensures that some unnecessary pipes are closed.
4159 *) Performance: Add quick_handler hook. This hook is called at the
4160 very beginning of the request processing before location_walk,
4161 translate_name, etc. This hook is useful for URI keyed content
4162 caches like Mike Abbott's Quick Shortcut Cache.
4165 *) top_module global variable renamed to ap_top_module [Perl]
4167 *) Move ap_set_last_modified to the core. This is a potentially
4168 controversial change, because this is kind of HTTP specific. However
4169 many protocols should be able to take advantage of this kind of
4170 information. I expect that headers will need one more layer of
4171 indirection for multi-protocol work, but this is a small step in
4172 the right direction. [Ryan Bloom]
4174 *) Enable mod_status by default. This matches what Apache 1.3 does.
4177 *) Add a ScriptSock directive to the default config file. This is
4178 only enabled when mod_cgid is used.
4179 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4181 Changes with Apache 2.0.15
4183 *) Untangled the buildconf script and eliminated the need for build's
4184 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
4185 libtool muck that is now under srclib/apr/build. [Roy Fielding]
4187 *) Win32: Don't accept more connections than we have worker threads
4191 *) Fix bug in the Unix threaded.c MPM that allowed child processes
4192 to fork() new child processes.
4195 *) SECURITY: Fix a major security problem with double-reverse lookup
4196 checking. Previously, a client connecting over IPv4 would not be
4197 matched properly when the server had an IPv6 listening socket.
4198 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
4200 *) Change the way the beos MPM handles polling to allow it to stop and
4201 restart. Problem was the sockets being polled were being reset by
4202 the select call, so once it had accepted a connection it was no
4203 longer listening on the UDP socket we use for shutdown instructions.
4204 APR needs to be altered, patch on it's way. [David Reid]
4206 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
4207 on error exit from ap_getline(). Some other code got upset because
4208 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
4210 *) Handle ap_discard_request_body() being called more than once.
4211 [Greg Ames, Jeff Trawick]
4213 *) Get rid of an inadvertent close of file descriptor 2 in
4214 mod_mime_magic. [Greg Ames, Jeff Trawick]
4216 *) Add a hook, create_request. This hook allows modules to modify
4217 a request while it is being created. This hook is called for all
4218 request_rec's, main request, sub request, and internal redirect.
4219 When this hook is called, the r->main, r->prev, r->next
4220 pointers have been set, so modules can determine what kind of
4221 request this is. [Ryan Bloom]
4223 *) Cleanup the build process a bit more. The Apache configure
4224 script no longer creates its own helper scripts, it just
4226 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4228 *) Stop the forced downgrade of the connection to HTTP/1.0 for
4229 proxy requests. [Graham Leggett]
4231 *) Avoid using sscanf to determine the HTTP protocol number in
4232 the common case because sscanf is a performance hog. From
4233 Mike Abbot's Accelerating Apache patch number 6.
4234 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
4236 *) SECURITY: Fix a security exposure in mod_access. Previously when
4237 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
4238 were not evaluated properly (PR #7407). Also, add the ability to
4239 specify IPv6 address strings with optional prefix length on Allow
4240 and Deny. [Jeff Trawick]
4242 *) Enhance rotatelogs so that a UTC offset can be specified, and
4243 the logfile name can be formatted using strftime(3). (Brought
4244 forward from 1.3.) [Ken Coar]
4246 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
4247 DuplicateHandle on an IOCompletionPort (a practice which
4248 MS "discourages"). The new model does not rely on associating
4249 the completion port with the listening sockets, thus the
4250 completion port can be completely managed within the child
4251 process. A dedicated thread accepts connections off the network,
4252 then calls PostQueuedCompletionStatus() to wake up worker
4253 threads blocked on the completion port.
4256 *) Bring forward the --suexec-umask option which allows the
4257 builder to preset the umask for suexec processes. [Ken Coar]
4259 *) Add a -V flag to suexec, which causes it to display the
4260 compile-time settings with which it was built. (Only
4261 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
4263 *) Mod_include should always unset the content-length if the file is
4264 going to be passed through send_parsed_content. There is no to
4265 determine if the content will change before actually scanning the
4266 entire content. It is far safer to just remove the C-L as long
4267 as we are scanning it. [Ryan Bloom]
4269 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
4270 request and not Proxy-Authenticate.
4271 [Graham Leggett <minfrin sharp.fm>]
4273 Changes with Apache 2.0.14
4275 *) Fix content-length computation. We ONLY compute a content-length if
4276 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
4277 or we already have all the data. [Ryan Bloom]
4279 *) Report unbounded containers in the config file. Previously, a typo
4280 in the </container> directive could result in the rest of the config
4281 file being silently ignored, with undesired defaults used.
4284 *) Make the old_write filter use the ap_f* functions for the buffering.
4287 *) Move more code from the http module into the core server. This
4288 is core code, basically the default handler, the default input
4289 and output filters, and all of the core configuration directives.
4290 All of this code is required in order for the server to work, with or
4291 without HTTP. The server is closer to working without the HTTP
4292 module, although there is still more to do. [Ryan Bloom]
4294 *) Fix a number of SGI compile warnings throughout the server. Fix some
4295 bad parameters to apr_bucket_read(). Fix a bad statement in
4296 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
4297 consistently; we were mixing apr_time_t and time_t in invalid ways
4298 before. In load_file(), call apr_dso_error() instead of
4299 apr_strerror() so that we get a more specific string on some platforms.
4300 PR #6980 [Jeff Trawick]
4302 *) Allow modules to query the MPM about it's execution profile. This
4303 query API can and should be extended in the future, but for now,
4304 max_daemons, and threading or forking is a very good start.
4305 [Jon Travis <jtravis covalent.net>]
4307 *) Modify mod_include to send blocks of data no larger than 9k.
4308 Without this, mod_include will wait until the whole file is parsed,
4309 or the first tag is found to send any data to the client.
4310 [Paul J. Reder <rederpj raleigh.ibm.com>]
4312 *) Fix mod_info, so that <Directory> and <Location> directives are
4313 not displayed twice when displaying the current configuration.
4314 [Ryan Morgan <rmorgan covalent.net>]
4316 *) Add config directives to override DEFAULT_ERROR_MSG and
4317 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
4318 [Dan Rench <drench xnet.com>]
4320 *) Get mod_info building and loading on Win32. [William Rowe]
4322 *) Begin to move protocol independant functions out of mod_http. The goal
4323 is to have only functions that are HTTP specific in the http directory.
4326 Changes with Apache 2.0.13
4328 *) Don't assume that there will always be multiple calls to the byterange
4329 filter. It is possible that we will need to do byteranges with only
4330 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
4332 *) Move the error_bucket definition from the http module to the
4333 core server. Every protocol will need this ability, not just
4336 Changes with Apache 2.0.12
4338 *) Modify mod_file_cache to save pre-formatted strings for
4339 content-length and last-modified headers for performance.
4340 [Mike Abbot <mja trudge.engr.sgi.com>]
4342 *) Namespace protect IOBUFSIZ since it is exposed in the API.
4343 [Jon Travis <jtravis covalent.net>]
4345 *) Use "Basic" authentication instead of "basic" in ab, as the spec
4346 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
4348 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
4349 without ever filling it out. This fixes PR 7271.
4350 [Taketo Kabe <kabe sra-tohoku.co.jp> and
4351 Cliff Woolley <cliffwoolley yahoo.com>]
4353 *) Add a couple of GCC attribute tags to printf style functions.
4354 [Jon Travis <jtravis covalent.net>]
4356 *) Add the correct language tag for interoperation with the Taiwanese
4357 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
4359 *) Migrate the perchild MPM to use the new apr signal child, and
4360 APR thread functions. [Ryan Bloom]
4362 *) Close one copy of the CGI's stdout before creating the new process.
4363 The CGI will still have stdout, because we have already dup'ed it.
4364 This keeps Apache from waiting forever to send the results of a CGI
4365 process that has forked a long-lived child process.
4366 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4368 *) Remove the rest of the pthreads functions from the threaded MPM.
4369 This requires the APR support for a signal thread that was just
4372 *) Make mod_dir use a fixup for sending a redirect to the browser.
4373 Before this, we were using a handler, which doesn't make much
4374 sense, because the handler wasn't generating any data, it would
4375 either return a redirect error code, or DECLINED. This fits the
4376 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
4378 *) Make the threaded MPM use APR threads instead of pthreads.
4381 *) Get mod_tls to the point where it actually appears to work in all cases.
4384 *) implement --enable-modules and --enable-mods-shared for "all" and
4385 "most". [Greg Stein]
4387 *) Move the threaded MPM to use APR locks instead of pthread locks.
4390 *) Rename mpmt_pthread to threaded. This is more in line with the
4391 fact that mpmt_pthread shouldn't be using pthreads directly, and
4392 it is a smaller name that doesn't tie into anything.
4395 *) Rename the module structures so that the exported symbol matches
4396 the file name, and it is easier to automate the installation
4397 process (generating LoadModule directives from the module filenames).
4400 *) Remove the coalesce filter. With the ap_f* functions, this filter
4401 is no longer needed. [Ryan Bloom]
4403 Changes with Apache 2.0.11
4405 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
4406 added feature of allowing a uid/gid per child process. If no
4407 uid/gid is specified, then Perchild behaves exactly like dexter.
4410 *) Get perchild building again. [Ryan Bloom]
4412 *) Don't disable threads just because we are using the prefork MPM.
4413 If somebody wants to compile without threads, they must now add
4414 --disable-threads to the configure command line. [Ryan Bloom]
4416 *) Begin to move the calls to update_child_status into common code, so
4417 that each individual MPM does not need to update the scoreboard itself.
4420 *) Allow mod_tls to compile under Unix boxes where openssl has been
4421 installed to the system include files.
4422 [Gomez Henri <new-httpd slib.fr>]
4424 *) Cleanup the mod_tls configure process. This should remove any need
4425 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
4426 configure doesn't check that yet. [Ryan Bloom]
4428 *) Add a very early prototype of SSL support (in mod_tls.c). It is
4429 vital that you read modules/tls/README before attempting to build
4432 *) Fix a potential seg fault on all platforms. David Reid fixed this
4433 on BEOS, but the problem could happen anywhere, so we don't want
4434 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
4436 *) Add new LogFormat directive, %D, to log time it takes to serve a
4437 request in microseconds. [Bill Stoddard]
4439 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
4440 SetOutputFilter. This corresponds nicely with the other Set
4441 directives, which operate on containers while the Add* directives
4442 tend to work directly on extensions. [Ryan Bloom]
4444 *) Cleanup the header handling a bit. This uses the apr_brigade_*
4445 functions for the buffering so that we don't need to compute
4446 the length of the headers before we actually create the header
4447 buffer. [Ryan Bloom]
4449 *) Allow filters to buffer data using the ap_f* functions. These have
4450 become macros that resolve directly to apr_brigade_*.
4453 *) Get the Unix MPM's to do a graceful restart again. If we are going
4454 to register a cleanup with ap_cleanup_scoreboard, then we have to
4455 kill the cleanup with the same function, and that function can't be
4456 static. [Ryan Bloom]
4458 *) Install all required header files. Without these, it was not
4459 possible to compile some modules outside of the server.
4462 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
4463 forward from 1.3 to 2.0, we missed a single line, which broke regex
4464 aliases. [Ryan Bloom]
4466 *) We have a poor abstraction in the protocol. This is a temporary
4467 hack to fix the bug, but it will need to be fixed for real. If
4468 we find an error while sending out a custom error response, we back
4469 up to the first non-OK request and send the data. Then, when we send
4470 the EOS from finalize_request_protocol, we go to the last request,
4471 to ensure that we aren't sending an EOS to a request that has already
4472 received one. Because the data is sent on a different request than
4473 the EOS, the error text never gets sent down the filter stack. This
4474 fixes the problem by finding the last request, and sending the data
4475 with that request. [Ryan Bloom]
4477 *) Make the server status page show the correct restart time, and
4478 thus the proper uptime. [Ryan Bloom]
4480 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
4481 should reduce the amount of duplicate code that is required to
4482 create CGI processes.
4483 [Paul J. Reder <rederpj raleigh.ibm.com>]
4485 *) ap_new_connection() closes the socket and returns NULL if a socket
4486 call fails. Usually this is due to a connection which has been
4487 reset. [Jeff Trawick]
4489 *) Move the Apache version information out of httpd.h and into release.h.
4490 This is in preparation for the first tag with the new tag and release
4491 system. [Ryan Bloom]
4493 *) Begin restructuring scoreboard code to enable adding back in
4494 the ability to use IPC other than shared memory.
4495 Get mod_status working on Windows again. [Bill Stoddard]
4497 *) Make mod_status work with 2.0. This will work for prefork,
4498 mpmt_pthread, and dexter. [Ryan Bloom]
4500 *) Correct a typo in httpd.conf.
4501 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
4503 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
4505 *) Get the correct IP address if ServerName isn't set and we can't
4506 find a fully-qualified domain name at startup.
4507 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
4509 *) Make mod_cgid work with SuExec. [Ryan Bloom]
4511 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
4512 'extra' stat's for user/group since they should never occur, and now
4513 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
4514 volumes. [William Rowe]
4516 *) Adopt apr features to simplify mod_includes. This changes the
4517 behavior of the USER_NAME variable, unknown uid's are now reported
4518 as USER_NAME="<unknown>" rather than the old user#000 result.
4519 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
4521 *) Adopt apr features for simplifing mod_userdir, and accept the new
4522 Win32/OS2 exceptions without hiccuping. [William Rowe]
4524 *) Replace configure --with-optim option by using and saving the
4525 environment variable OPTIM instead. This is needed because configure
4526 options do not support multiple flags separated by spaces.
4529 *) Fix some byterange handling. If we get a byte range that looks like
4530 "-999999" where that is past the end of the file, we should return
4531 a PARTIAL CONTENT status code, and return the whole file as one big
4532 byterange. This matches the 1.3 handling now. [Ryan Bloom]
4534 *) Make the error bucket a real meta-data bucket. This means that the
4535 bucket length is 0, and a read returns NULL data. If one of these
4536 buckets is passed down after the headers are sent, this data will
4537 just be ignored. [Greg Stein]
4539 *) The prefork MPM wasn't killing child processes correctly if a restart
4540 signal was received while the process was serving a request. The child
4541 process would become the equivalent of a second parent process. If
4542 we break out of the accept loop, then we need to do die after cleaning
4543 up after ourselves. [Ryan Bloom]
4545 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
4546 restarts. [Ryan Bloom]
4548 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
4549 the most optimal APR_FINFO_wanted bits. This spares Win32 from
4550 performing very expensive owner, group and permission lookups
4551 and allows the server to function until these apr_finfo_t fields
4552 are implemented under Win32. [William Rowe]
4554 *) Support for typedsafe optional functions - that is functions exported by
4555 optional modules, which, therefore, may or may not be present, depending
4556 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
4557 for sample code. [Ben Laurie]
4559 *) filters can now report an HTTP error to the server. This is done
4560 by sending a brigade where the first bucket is an error_bucket.
4561 This bucket is a simple bucket that stores an HTTP error and
4562 a string. Currently the string is not used, but it may be needed
4563 to output an error log. The http_header_filter will find this
4564 bucket, and output the error text, and then return
4565 AP_FILTER_ERROR, which informs the server that the error web page
4566 has already been sent. [Ryan Bloom]
4568 *) If we get an error, then we should remove all filters except for
4569 those critical to serving a web page. This fixes a bug, where
4570 error pages were going through the byterange filter, even though
4571 that made no sense. [Ryan Bloom]
4573 *) Relax the syntax checking of Host: headers in order to support
4574 iDNS. PR#6635 [Tony Finch]
4576 *) Cleanup the byterange filter to use the apr_brigade_partition
4577 and apr_bucket_copy functions. This removes a lot of very messy
4578 code, and hopefully makes this filter more stable.
4581 *) Remove AddModule and ClearModuleList directives. Both of these
4582 directives were used to ensure that modules could be enabled
4583 in the correct order. That requirement is now gone, because
4584 we use hooks to ensure that modules are in the correct order.
4587 *) When SuExec is specified, we need to add it to the list of
4588 targets to be built. If we don't, then any changes to the
4589 configuration won't affect SuExec, unless 'make suexec' is
4590 specifically run. [Ryan Bloom]
4592 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4593 the APR_XTHREAD argument to open a file for consumption by
4594 parallel threads on win32. [William Rowe]
4596 *) Correct a bug in determining when we follow symlinks. The code
4597 expected a stat -1 result, not an apr_status_t positive error.
4598 Also check if the APR_FINFO_USER fields are valid before we
4599 follow the link. [William Rowe]
4601 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4602 mpm_common.c. These functions are only valid on some platforms,
4603 so they should not be in the main-line code. [Ryan Bloom]
4605 *) Remove ap_chdir_file(). This function is not thread-safe,
4606 and nobody is currently using it. [Ryan Bloom]
4608 *) Do not try to run make depend if there are no .c files in the
4609 current directory, doing so makes `make depend` fail.
4612 *) Update highperformance.conf to work with either prefork or
4613 pthreads mpms. [Greg Ames]
4615 *) Stop checking to see if this is a pipelined request if we know
4616 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4617 This keeps us from making an extra read call when serving a 1.0
4618 request. [Ryan Bloom and Greg Stein]
4620 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4621 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4622 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4624 *) Fix the RFC number mentioned when complaining about a missing
4625 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
4627 *) Fix an endless loop in ab which occurred when ab was posting
4628 and the server dropped the connection unexpectedly.
4631 *) Fix a segfault while handling request bodies in ap_http_filter().
4632 This problem has been seen with mod_dav usage as well as with
4633 requests where the body was just being discarded. [Jeff Trawick]
4635 *) Some adjustment on the handling and automatic setting (via
4636 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4637 add the capability to specify flags (NOTEST_CFLAGS and
4638 NOTEST_LDFLAGS) which are used to compile Apache, but
4639 not used during the configuration process. Useful for
4640 flags like "-Werror". [Jim Jagielski]
4642 *) Stop using environment variables to force debug mode or
4643 no detach. We now use the -D command line argument to
4644 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4645 [Greg Stein, Ryan Bloom]
4647 *) Change handlers to use hooks. [Ben Laurie]
4649 *) Stop returning copies of filenames from both apr_file_t and
4650 apr_dir_t. We pstrdup the filenames that we store in the
4651 actual structures, so we don't need to pstrdup the strings again.
4654 *) mod_cgi: Fix some problems where the wrong error value was being
4655 traced. [Jeff Trawick]
4657 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
4660 *) Add generic hooks. [Ben Laurie]
4662 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
4664 *) Fix a segfault caused by mod_ext_filter when the external filter
4665 program does not exist. [Jeff Trawick]
4667 *) Fix an output truncation error when on an HTTP >= 1.0 request an
4668 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
4669 was served through mod_charset_lite (or anything else that would
4670 create a transient bucket in this size range). ap_bucket_make_heap()
4671 silently failed (fixed), transient_setaside() discovered it, but
4672 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
4674 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
4675 is that some browsers send extra lines at the end of POST requests, and
4676 we don't want to delay sending data back to the user just because the
4677 browser isn't well behaved. [Ryan Bloom]
4679 *) Get SuEXEC working again. We can't send absolute paths to suExec
4680 because it refuses to execute those programs. SuEXEC also wasn't
4681 always recognizing configuration changes made using the autoconf
4684 *) Allow the buildconf process to find the config.m4 files in the correct
4685 order. Basically, we can now name config.m4 files as config\d\d.m4,
4686 and we will sort them correctly when inserting them into the build
4687 process. [Ryan Bloom]
4689 *) Get mod_cgid to use apr calls for creating the actual CGI process.
4690 This also allows mod_cgid to use ap_os_create_priviledged_process,
4691 thus allowing for SuExec execution from mod_cgid. Currently, we do
4692 not support everything that standard SuExec supports, but at least
4693 it works minimally now. [Ryan Bloom]
4695 *) Allow SuExec to be configured from the ./configure command line.
4698 *) Update some of the docs in README and INSTALL to reflect some of
4699 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
4701 *) If we get EAGAIN returned from the call to apr_sendfile, then we
4702 need to call sendfile again. This gets us serving large files
4703 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
4705 *) Get the support programs building cleanly again.
4706 [Cliff Woolley <cliffwoolley yahoo.com>]
4708 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
4709 current directory logic now backs up over bin/ to determine the
4710 server root from the Apache.exe path.
4712 *) Apache/Win32 now follows the standard conventions of mod_foo.so
4713 loadable modules, dynamic libs are all named libfoo.dll, and the
4714 makefile.win populates the include, lib and libexec directories.
4716 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
4717 Apache gets IPv6 listening sockets by default. Additionally, the
4718 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
4719 numeric address strings (e.g., "Listen [fe80::1]:8080").
4722 *) Modify the install directory layout. Modules are now installed in
4723 modules/. Shared libraries should be installed in libraries/, but
4724 we don't have any of those on Unix yet. All install directories
4725 are modifyable at configure time. [Ryan Bloom]
4727 *) Install all header files in the same directory on Unix. [Ryan Bloom]
4729 *) Get the functions in server/linked into the server, regardless of
4730 which modules linked into the server. This uses the same hack
4731 for Apache that we use for APR and apr-util to ensure all of the
4732 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
4733 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
4734 the scripts a bit easier.
4737 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
4738 on the query, and remove IPv4 dependencies. [Jeff Trawick]
4740 *) Get all of the auth modules to the point that they will install and
4741 be loadable into the server. Our new build/install mechanism expects
4742 that all modules will have a common name format. The auth modules
4743 didn't use that format, so we didn't install them properly.
4746 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
4747 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
4749 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
4751 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
4752 after the end of the response. [Ryan Bloom]
4754 *) Get byterange requests working with responses that do not have a
4755 content-length. Because of the way byterange requests work, we have to
4756 have all of the data before we can actually do the byterange, so we
4757 can compute the content-length in the byterange filter.
4760 *) Get exe CGI's working again on Windows.
4763 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
4764 they keep track of whether or not their post config hook has been
4765 called before. Instead of a static variable (which is replaced when
4766 the DSO is loaded a second time), use userdata in the process pool.
4769 Changes with Apache 2.0a9
4771 *) Win32 now requires perl to complete the final install step for users
4772 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
4773 and installs the conf, htdocs and htdocs/manual directories.
4776 *) Make mod_include use a hash table to associate directive tags with
4777 functions. This allows modules to implement their own SSI tags easily.
4778 The idea is simple enough, a module can insert it's own tag and function
4779 combination into a hash table provided by mod_include. While mod_include
4780 parses an SSI file, when it encounters a tag in the file, it does a
4781 hash lookup to find the function that implements that tag, and passes
4782 all of the relevant data to the function. That function is then
4783 responsible for processing the tag and handing the remaining data back
4784 to mod_include for further processing.
4785 [Paul J. Reder <rederpj raleigh.ibm.com>]
4787 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
4788 fewer parameters: the local and remote socket addresses were removed
4789 from the parameter list because all required information is available
4790 via the APR socket. [Jeff Trawick]
4792 *) Distribution directory structure reorganized to reflect a
4793 normal source distribution with external install targets.
4796 *) The MPMs that need multiple segments of shared memory now create
4797 two apr_shmem_t variables, one for each shared memory allocation.
4798 the problem is that we can't determine how much memory will be required
4799 for shared memory allocations once we try to allocate more than one
4800 variable. The MM code automatically aligns the shared memory allocations,
4801 so we end up needing to pad the amount of shared memory we want based
4802 on how many variables will be allocated out of the shared memory segment.
4803 It is just easier to create a second apr_shmem_t variable, and two
4804 shmem memory blocks.
4807 *) Cleanup the export list a bit. This creates a single unified list of
4808 functions exported by APR. The export list is generated at configure
4809 time, and that list is then used to generate the exports.c file.
4810 Because of the way the export list is generated, we only export those
4811 functions that are valid on the platform we are building on.
4814 *) Enable logging the cookie with mod_log_config
4815 [Sander van Zoest <sander covalent.net>]
4817 *) Fix a segfault in mod_info when it reaches the end of the configuration.
4820 *) Added lib/aputil/ as a placeholder for utility functions which are not
4821 specific to the Apache HTTP Server (but do not make sense with APR).
4822 The first utility is "apu_dbm": a set of functions to work with DBM
4823 files. This first version can be compiled for SDBM or GDBM databases.
4826 *) Complete re-write of mod_include. This makes mod_include a filter that
4827 uses buckets directly. This has now served the FAQ correctly.
4828 [Paul Reder <rederpj raleigh.ibm.com>]
4830 *) Allow modules to specify the first filter in a sub_request when
4831 making the sub_request. This keeps modules from having to change the
4832 output_filter immediately after creating the sub-request, and therefore
4833 skip the sub_req_output_filter. [Ryan Bloom]
4835 *) Update ab to accept URLs with IPv6 literal address strings (in the
4836 format described in RFC 2732), and to build Host header fields in
4837 the same format. This allows IPv6 literal address strings to be
4838 used with ab. This support has been tested against Apache 1.3 with
4839 the KAME patch, but Apache 2.0 does not yet work with this format
4840 of the Host header field. [Jeff Trawick]
4842 *) Accomodate an out-of-space condition in the piped logs and the
4843 rotatelogs.c code, and no longer churn log processes for this
4844 condition. [Victor J. Orlikowski]
4846 *) Add support for partial writes with apr_sendfile() to core_output_filter.
4849 Changes with Apache 2.0a8
4851 *) Add a directive to mod_mime so that filters can be associated with
4855 *) Get multi-views working again. We were setting the path_info
4856 field incorrectly if we couldn't find the specified file.
4859 *) Fix 304 processing. The core should never try to send the headers
4860 down the filter stack. Always, just setup the table in the request
4861 record, and let the header filter convert it to data that is ready
4865 *) More fixes for the proxy. There are still bugs in the proxy code,
4866 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
4870 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
4873 *) APR: Add new apr_getopt_long function to handle long options.
4874 [B. W. Fitzpatrick <fitz red-bean.com>]
4876 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
4877 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
4878 hostname resolution/address string parsing and building
4879 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
4880 of one of the apr_sockaddr_t structures for a socket. Change
4881 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
4883 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
4884 I have proxied pages with it, cleanup will commence soon.
4887 *) Make the proxy work with filters. This isn't perfect, because we
4888 aren't dealing with the headers properly. [Ryan Bloom]
4890 *) Do not send a content-length iff the C-L is 0 and this is a head
4891 request. [Ryan Bloom]
4893 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
4894 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
4896 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
4898 *) Get the default_handler to stop trying to deal with HEAD requests.
4899 The idea is to let the content-length filter compute the C-L before
4900 we try to send the data. If we can get the C-L correctly, then we
4901 should send it in the HEAD response.
4904 *) The Header filter can now determine if a body should be sent based
4905 on r->header_only. The general idea of this is that if we delay
4906 deciding to send the body, then we might be able to compute the
4907 content-length correctly, which will help caching proxies to cache
4908 our data better. Any handler that doesn't want to try to compute
4909 the content-length can just send an EOS bucket without data and
4910 everything will just work.
4913 *) Add the referer to the error log if one is available.
4914 [Markus Gyger <mgyger itr.ch>]
4916 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
4917 change, the root of the configuration tree has been exposed to modules
4919 [Ryan Morgan <rmorgan covalent.net>]
4921 *) Get the core_output_filter to use the bucket interface directly.
4922 This keeps us from calling the content-length filter multiple times
4923 for a simple static request.
4926 *) We are sending the content-type correctly now.
4927 [Ryan Bloom and Will Rowe]
4929 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
4930 a bogus bytes-sent value when the only thing being sent was trailers
4931 and writev() returned an error (or EAGAIN). [Jeff Trawick]
4933 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
4934 hints file to determine which platforms define
4935 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
4938 *) APR: add apr_get_home_directory() [Jeff Trawick]
4940 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
4942 *) Not all platforms have INADDR_NONE defined by default. Apache
4943 used to make this check and define INADDR_NONE if appropriate,
4944 but APR needs the check too, and I suspect other applications will
4945 as well. APR now defines APR_INADDR_NONE, which is always a valid
4946 value on all platforms.
4947 [Branko Èibej <brane xbc.nu>]
4949 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
4950 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
4952 *) Relax the syntax checking of Host: headers in order to support
4953 iDNS. PR#6635 [Tony Finch]
4955 *) When reading from file buckets we convert to an MMAP if it makes
4956 sense. This also simplifies the default handler because the
4957 default handler no longer needs to try to create MMAPs.
4960 *) BUFF has been removed from the main server. The BUFF code will remain
4961 in the code until it has been purged from the proxy module as well.
4964 *) Byteranges have been completely re-written to be a filter. This
4965 has been tested, and I believe it is working correctly, but it could
4966 doesn't work for the Adobe Acrobat plug-in. The output almost matches
4967 the output from 1.3, the only difference being that 1.3 includes
4968 a content-length in the response, and this does not.
4971 *) APR read/write functions and bucket read functions now operate
4972 on unsigned integers, instead of signed ones. It doesn't make
4973 any sense to use signed ints, because we return the error codes,
4974 so if we have an error we should report 0 bytes read or written.
4977 *) Always compute the content length, whether it is sent or not.
4978 The reason for this, is that it allows us to correctly report
4979 the bytes_sent when logging the request. This also simplifies
4980 content-length filter a bit, and fixes the actual byte-reporing
4981 code in mod_log_config.c
4984 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
4985 it says, because it was only used by EOS and FLUSH buckets. Since
4986 neither of those are required at the end of a brigade, this was
4987 really signifying FLUSH_THE_DATA, but that can be determined better
4988 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
4989 buckets now return a length of 0, which is actually the amount of data
4990 read, so they make more sense.
4993 *) Allow the core_output_filter to save some data past the end of a
4994 request. If we get an EOS bucket, we only send the data if it
4995 makes sense to send it. This allows us to pipeline request
4996 responses. As a part of this, we also need to allocate mmap
4997 buckets out of the connection pool, not the request pool. This
4998 allows the mmap to outlive the request.
5001 *) Make blocking and non-blocking bucket reads work correctly for
5002 sockets and pipes. These are the only bucket types that should
5003 have non-blocking reads, because the other bucket types should
5004 ALWAYS be able to return something immediately.
5007 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
5008 server, but use Ctrl+Break to initiate a graceful restart
5009 instead of duplicating behavior. [John Sterling]
5011 *) Patch mod_autoindex to set the Last-Modified header based on
5012 the directory's mtime, and add the ETag header. [William Rowe]
5014 *) Merge the 1.3 patch to add support for logging query string in
5015 such a way that "%m %U%q %H" is the same as "%r".
5018 *) Port three log methods from mod_log_config 1.3 to 2.0:
5019 CLF compliant '-' byte count, method and protocol.
5022 *) Add a new LogFormat directive, %c, that will log connection
5023 status at the end of the response as follows:
5024 'X' - connection aborted before the response completed.
5025 '+' - connection may be kept-alive by the server.
5026 '-' - connection will be closed by the server.
5029 *) Expand APR for WinNT to fully accept and return utf-8 encoded
5030 Unicode file names and paths for Win32, and tag the Content-Type
5031 from mod_autoindex to reflect that charset if the feature
5032 macro APR_HAS_UNICODE_FS is true. [William Rowe]
5034 *) Compute the content length (and add appropriate header field) for
5035 the response when no content length is available and we can't use
5036 chunked encoding. [Jeff Trawick]
5038 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
5039 so that content input filters get dechunked data when using
5040 the default handler. Also removed REQUEST_CHUNKED_PASS.
5043 *) Add mod_ext_filter as an experimental module. This module allows
5044 the administrator to use external programs as filters. Currently,
5045 only filtering of output is supported. [Jeff Trawick]
5047 *) Most Apache functions work on EBCDIC machines again, as protocol
5048 data is now translated (again). [Jeff Trawick]
5050 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
5051 the EBCDIC support. They are noops on ASCII machines, so this
5052 type of translation doesn't have to be surrounded by #ifdef
5053 CHARSET_EBCDIC. [Jeff Trawick]
5055 *) Fix mod_include. tag commands work again, and the server will
5056 send the FAQ again. This also allows mod_include to set aside
5057 buckets that include partial buckets.
5058 [Ryan Bloom and David Reid]
5060 *) Add suexec support back. [Manoj Kasichainula]
5062 *) Lingering close now uses the socket directly instead of using
5063 BUFF. This has been tested, but since all we can tell is that it
5064 doesn't fail, this needs to be really hacked on.
5067 *) Allow filters to modify headers and have those headers be sent to
5068 the client. The idea is that we have an http_header filter that
5069 actually sends the headers to the network. This removes the need
5070 for the BUFF to send headers.
5073 *) Charset translation: mod_charset_lite handles translation of
5074 request bodies. Get rid of the xlate version of ap_md5_digest()
5075 since we don't compute digests of filtered (e.g., translated)
5076 response bodies this way anymore. (Note that we don't do it at
5077 all at the present; somebody needs to write a filter to do so.)
5080 *) Input filters and ap_get_brigade() now have a input mode parameter
5081 (blocking, non-blocking, peek) instead of a length parameter.
5084 *) Update the mime.types file to the registered media types as
5085 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
5088 *) Namespace protect some macros declared in ap_config.h
5091 *) Support HTTP header line folding with input filtering.
5094 *) Mod_include works again. This should still be re-written, but at
5095 least now we can serve an SHTML page again.
5098 *) Begin to remove BUFF from the core. Currently, we keep a pointer
5099 to both the BUFF and the socket in the conn_rec. Functions that
5100 want to use the BUFF can, functions that want to use the socket,
5101 can. They point to the same place.
5104 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
5105 [Tomas "Ögren" <stric ing.umu.se>]
5107 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
5108 associated pool goes away. (APR pipes on OS/2 were already had this
5109 logic.) This resolvs a fatal file descriptor leak with CGIs.
5112 *) The final line of the config file was not being read if there was
5113 no \n at the end of it. This was caused by apr_fgets returning
5114 APR_EOF even though we had read valid data. This is solved by
5115 making cfg_getline check the buff that was returned from apr_fgets.
5116 If apr_fgets return APR_EOF, but there was data in the buf, then we
5117 return the buf, otherwise we return NULL.
5120 *) Piped logs work again in the 2.0 series.
5123 *) Restore functionality broken by the mod_rewrite security fix:
5124 rewrite map lookup keys and default values are now expanded
5125 so that the lookup can depend on the requested URI etc.
5126 PR #6671 [Tony Finch]
5128 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
5129 security bug in some mass virtual hosting configurations
5130 that can allow a remote attacker to retrieve some files
5131 on the system that should be inaccessible. [Tony Finch]
5133 *) Add a pool bucket type. This bucket is used for data allocated out
5134 of a pool. If the pool is cleaned before the bucket is destroyed, then
5135 the data is converted to a heap bucket, allowing it to survive the
5139 *) Add a flush bucket. This allows modules to signal that the filters
5140 should all flush whatever data they currently have. There is no way
5141 to actually force them to do this, so if a filter ignores this bucket,
5142 that's life, but at least we can try with this.
5145 *) Add an output filter for sub-requests. This filter just strips the
5146 EOS bucket so that we don't confuse the main request's core output
5147 filter by sending multiple EOS buckets. This change also makes sub
5148 requests start to send EOS buckets when they are finished.
5151 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
5152 makes ap_bucket_destroy a return void, which is okay because it
5153 used to always return APR_SUCCESS, and nobody ever checked its
5154 return value anyway.
5155 [Cliff Woolley <cliffwoolley yahoo.com>]
5157 *) Remove the index into the bucket-type table from the buckets
5158 structure. This has now been replaced with a pointer to the
5159 bucket_type. Also add some macros to test the bucket-type.
5162 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
5163 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
5164 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
5165 All _VAR_ flavors changes to _DATA to be absolutely clear.
5168 *) Add support for /, //, //servername and //server/sharename
5169 parsing of <Directory> blocks under Win32 and OS2.
5170 [Tim Costello, William Rowe, Brian Harvard]
5172 *) Remove the function pointers from the ap_bucket type. They have been
5173 replaced with a global table. Modules are allowed to register bucket
5174 types and use then use those buckets.
5177 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
5178 once we finish writing the request body to the cgi child process;
5179 otherwise, the client doesn't hit EOF on stdin. Small request bodies
5180 worked without this change (for reasons I don't understand), but large
5181 ones didn't. [Jeff Trawick]
5183 *) Remove file bucket specific information from the ap_bucket type.
5184 This has been moved to a file_bucket specific type that hangs off
5185 the data pointer in the ap_bucket type.
5188 *) Input filtering now has a third argument. This is the amount of data
5189 to read from lower filters. This argument can be -1, 0, or a positive
5190 number. -1 means give me all the data you have, I'll deal with it and
5191 let you know if I need more. 0 means give me one line and one line
5192 only. A positive number means I want no more than this much data.
5194 Currently, only 0 and a positive number are implemented. This allows
5195 us to remove the remaining field from the conn_rec structure, which
5199 *) Big cleanup of the input filtering. The goal is that http_filter
5200 understands two conditions, headers and body. It knows where it is
5201 based on c->remaining. If c->remaining is 0, then we are in headers,
5202 and http_filter returns a line at a time. If it is not 0, then we are
5203 in body, and http_filter returns raw data, but only up to c->remaining
5204 bytes. It can return less, but never more.
5205 [Greg Ames, Ryan Bloom, Jeff Trawick]
5207 *) mod_cgi: Write all of the request body to the child, not just what
5208 the kernel would accept on the first write. [Jeff Trawick]
5210 *) Back out the change that moved the brigade from the core_output_filters
5211 ctx to the conn_rec. Since all requests over a given connection
5212 go through the same core_output_filter, the ctx pointer has the
5216 *) Fix another bug in the send_the_file() read/write loop. A partial
5217 send by apr_send would cause unsent data in the read buffer to
5218 get clobbered. Complete making send_the_file handle partial
5219 writes to the network.
5222 *) Fix a couple of type fixes to allow compilation on AIX again
5223 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
5225 *) Fix bug in send_the_file() which causes offset to be ignored
5226 if there are no headers to send.
5229 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
5230 filter. Useful for supporting Windows 9* with a binary
5231 compiled on Windows NT.
5234 Changes with Apache 2.0a7
5236 *) Reimplement core_output_filter to buffer/save bucket brigades
5237 across multiple calls to the core_filter. The brigade will be
5238 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
5239 thresholds are hit or the EOS bucket is received.
5242 *) Create experimental filter (buffer_filter) that coalesces bytes
5243 into one large buffer before invoking the next filter in the
5244 chain. This filter is particularly useful with the current
5245 implementation of mod_autoindex when it inserted above the
5246 chunk_filter. mod_autoindex generates a lot of brigades that
5247 containing buckets holding just a few bytes each. The
5248 buffer_filter coalesces these buckets into a single large bucket.
5251 *) Add apr_sendfile() support into the core_output_filter.
5254 *) Add apr_sendv() support into the core_output_filter.
5257 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
5258 [Mike Abbott <mja sgi.com>]
5260 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
5261 make much sense, because Apache uses buckets instead of BUFFs now.
5264 *) send_the_file now falls back to a read/write loop on platforms that
5265 do not have sendfile.
5266 [Ryan Bloom and Brian Havard]
5268 *) Install apachectl correctly, and substitute the proper values so
5269 that it works again. [Ryan Bloom]
5271 *) Better(??) handle platforms that lack sendfile().
5274 *) APR now has UUID generation/formatting/parsing support.
5277 *) Begin the http_filter. This is an input filter that understands
5278 the absolute basic amount required to parse an HTTP Request. The
5279 goal is to be able to split headers from request body before passing
5280 the data back to the other filters.
5283 *) Bring forward from 1.3.13 the config directory implementation
5286 *) install apxs if it is created
5289 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
5290 conversions. [William Rowe]
5292 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
5293 ap_add_output_filter(). [Jeff Trawick]
5295 *) Multiple build and configuration fixes
5298 -add datadir and localstatedir substitutions
5300 -fix logfilename misspelling
5301 -fix evaluation of installation dir variables and
5302 -replace $foobar by $(foobar) to be usefull in the makefile
5306 -add rules for cross-compiling in rules.mk. Okay, rule to check for
5307 $CC_FOR_BUILD is still missing
5308 -use CHECK_TOOL instead of CHECK_PROG for ranlib
5309 -add missing "AR=@AR@" to severaly Makefile.in's
5310 -cache result for "struct rlimit"
5311 -compile all helper programs with native and cross compiler
5312 and use the native version to generate header file
5313 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5315 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
5317 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5319 *) Fix a bug where a client which only sends \n to delimit header
5320 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
5321 message. Start working on ebcdic co-existance with input
5323 [William Rowe, Greg Ames]
5325 *) If mod_so is enabled in the server always create libexec, even
5326 if there are no modules installed in this directory. This is a
5327 requirement for APXS to work correctly.
5330 *) Connection oriented output filters are now stored in the
5331 conn_rec instead of the request_rec. This allows us to add the
5332 output filter in the pre-connection phase instead of the
5333 post_read_request phase, which keeps us from trying to write an
5334 error page before we have a filter to write to the network.
5335 [Ryan Bloom, Jeff Trawick, and Greg Ames]
5337 *) Cleaning up an mmap bucket no longer deletes the mmap. An
5338 mmap can be used across multiple buckets (default_handler with
5339 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
5340 the mmap itself can't be associated with the bucket.
5343 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
5346 *) Radical surgery to improve mod_isapi support under Win32.
5347 Includes a number of newer ServerSupportFunction calls, support
5348 for ReadClient (in order to retrieve POSTs greater than 48KB),
5349 and general bug fixes to more reliably load ISAPI .dll's and
5350 prevent leaking handle resources. Note: There are still
5351 discrepancies between IIS's and Apache's ServerVariables, and
5352 async calls are still not supported. Additional warnings are
5353 logged to facilitate debugging of unsupported ISAPI calls.
5356 *) Add input filtering to Apache. The basic idea for the input
5357 filters is the same as the ideas for output filters. The biggest
5358 difference is that instead of calling ap_pass_brigade, ap_get_brigade
5359 should be called, and the order of execution for the filter itself is
5360 different. When writing an output filter, a brigade is passed in,
5361 and filters operate directly on that brigade, when done, they call
5362 ap_pass_brigade. Input filters are the exact opposite. Because input
5363 is not a push operation, filters first call ap_get_brigade. When this
5364 function returns, the input filter will be left with a valid brigade.
5365 The input filter should then operate on the brigade, and return.
5368 *) Fix building on BSD/OS using its native make. The build system
5369 falls back to the BSD .include directive on that host platform.
5372 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
5373 SHA1 and plaintext password encodings. Make feature tests a
5374 bit more flexible. [William Rowe]
5376 *) Charset translation: mod_charset_lite handles output content
5377 translation in a filter. mod_charset_lite no longer ignores
5378 subrequests. A bunch of cruft related to BUFF's support for
5379 translating request and response bodies was removed.
5382 *) Move the addition of the CORE filter to the post_read_request
5383 hook in http_core.c. This removes the need to add the filter in
5384 multiple places and allows for an SSL module to be added much
5385 simpler. [Ryan Bloom]
5387 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
5388 Fix a security problem that affects certain configurations of
5389 mod_rewrite. If the result of a RewriteRule is a filename that
5390 contains expansion specifiers, especially regexp backreferences
5391 $0..$9 and %0..%9, then it may be possible for an attacker to
5392 access any file on the web server. [Tony Finch]
5394 *) Fix a bug where errors that are detected during early request parsing
5395 don't produce visible HTTP error messages at the browser, because
5396 the core_filter wasn't present. [Greg Ames]
5398 *) Provide apr_socklen_t as a portability aid.
5399 [Victor J. Orlikowski]
5401 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
5402 as well as a comment arg to the add, adduser and update cmds.
5403 update allows the user to clear or preserve pw/groups/comment.
5404 Fixed a bug in dbmmanage that prevented the check option from
5405 parsing a password followed by :group... text. Corrected the
5406 seed calcualation for Win32 systems, and added -lsdbm support.
5409 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
5412 *) Avoid a segfault when parsing .htaccess files. An
5413 uninitialized tree pointer was passed to ap_build_config().
5416 *) Change the way that inet_addr & inet_network are checked for
5417 in APR's configure process to allow BeOS BONE to correctly
5418 find them. With this change BeOS BONE now builds from source
5419 with no problems. [David Reid]
5421 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
5422 the end of the parameters to execve() was stored in the wrong
5423 location, overlaying the storage beyond the newargs[] array and
5424 also passing uninitialized storage to execve(), which would
5425 sometimes fail with EFAULT. [Jeff Trawick]
5427 *) Fix a bug parsing configuration file containers. With a sequence
5428 like this in the config file
5430 <IfModule mod_kilroy.c>
5433 <IfModule mod_lovejoy.c>
5438 the second container would be terminated at the blank line due to
5439 sediment in the buffer from reading the prior </IfModule> and an
5440 error message would be generated for the real </IfModule> for the
5441 second container. Also due to this problem, any two characters
5442 could be used for "</" in the close of a container.
5445 *) ap_add_filter prototype changed to remove the ctx pointer. The
5446 pointer still remains in the filter structure, but it can not be
5447 a part of the ap_add_filter prototype. The reason is that when
5448 the core uses AddFilter to add a filter to the stack it doesn't
5449 know how to allocate the ctx pointer, or even how much memory should
5450 be allocated. The filters will have to be responsible for allocating
5451 the ctx memory when they need it.
5454 *) Add an AddFilter directive. This directive takes a list of filters
5455 that should be activated for the requested resource.
5458 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
5459 some other platforms). [Jeff Trawick]
5461 *) Modify mod_include to be a filter. Currently, it has only been tested
5462 on actual files, but it should work for CGI scripts too.
5465 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
5466 writes. apr_flush() for Unix: handle interrupted writes.
5469 *) NameVirtualHost can now take "*" as an argument instead of
5470 an IP address. This allows you to create a purely name-based
5471 virtual hosting server that does not have any IP addresses in
5472 the configuration file and which ignores the local address
5473 of any connections. PR #5595, PR #4455 [Tony Finch]
5475 *) Fix some compile warnings in mod_mmap_static.c
5476 [Mike Abbott <mja sgi.com>]
5478 *) Fix chunking problem with CGI scripts. The general problem was that
5479 the CGI modules were adding an EOS bucket and then the core added an
5480 EOS bucket. The chunking filter finalizes the chunked response when it
5481 encounters an EOS bucket. Because two EOS buckets were sent, we
5482 finalized the response twice. The fix is to make sure we only send one
5483 EOS, by utilizing a flag in the request_rec.
5486 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
5487 and Win32. Previously, the first read from an apr_file_t set up via
5488 apr_put_os_file() would return a '\0'. [Jeff Trawick]
5490 *) Mod_cgid now creates a single element bucket brigade, with a pipe
5491 bucket, instead of using BUFF's and ap_r*.
5494 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
5495 [Mike Abbott <mja sgi.com>]
5497 *) Remove ap_bopenf from buff code. This required modifying the file_cache
5498 code to use APR file's directly instead of going through BUFFs.
5501 *) Fix compile break on some platforms for mod_mime_magic.c
5502 [John K. Sterling <sterling covalent.net>]
5504 *) Fix merging of AddDefaultCharset directive.
5505 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
5507 *) Minor revamp of the rlimit sections of code. We now test
5508 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
5509 is now "available" even if the platform doesn't support
5510 the rlimit family (it's just a noop though). [Jim Jagielski]
5512 *) Migrate the pre-selection of which MPM to use for specific
5513 platforms to hints.m4, which contains (or should contain)
5514 all platform specific "hints". [Jim Jagielski]
5516 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
5519 *) Add tables with non-string/binary values to APR.
5522 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
5525 *) Update PCRE to version 3.2. [Ryan Bloom]
5527 *) Change the way buckets' destroy functions are called so that
5528 they can be more directly used when changing the type of a
5529 bucket in place. [Tony Finch]
5531 *) Add generic support for reference-counting the resources used by
5532 buckets, and alter the HEAP and MMAP buckets to use it. Change
5533 the way buckets are initialised to support changing the type of
5534 buckets in place, and use it when setting aside TRANSIENT buckets.
5535 Change the implementation of TRANSIENT buckets so that it can be
5536 mostly shared with IMMORTAL buckets, which are now implemented.
5539 Changes with Apache 2.0a6
5541 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
5543 *) Add a chunking filter to Apache. This brings us one step closer
5544 to removing BUFF. [Ryan Bloom]
5546 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
5547 added to the stack is the last filter to be called. [Ryan Bloom]
5549 *) Apache 2.0 has been completely documented using Scandoc. The
5550 docs can be generated by running 'make docs'. [Ryan Bloom]
5552 *) Add filtered I/O to Apache. This is based on bucket brigades,
5553 Currently the buckets still use BUFF under the covers, but that
5554 should change quickly. The only currently written filter is the
5555 core filter which just calls ap_bwrite. [The Apache Group]
5557 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
5558 built with thread support. [Jeff Trawick]
5560 *) Abort configuration if --with-layout was specified and there's
5561 no layout definition file. [Ken Coar]
5563 *) Add support for '--with-port=n' option to configure. [Ken Coar]
5565 *) Add support for extension methods for the Allow response header
5566 field, and an API routine for accessing r->allowed and the
5567 list of extension methods in a unified manner. [Ken Coar]
5569 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5570 [Rob Simonson <simo us.ibm.com>]
5572 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5573 APACHE_XLATE builds. [Jeff Trawick]
5575 *) A configuration file parsing problem was fixed. When the
5576 configuration file started with an IfModule/IfDefine container,
5577 only the last statement in the container would be retained.
5580 Changes with Apache 2.0a5
5582 *) Perchild is serving pages after passing them to different child
5583 processes. There are still a lot of bugs, but this does work. I
5584 have made requests against the same installation of Apache, and had
5585 different servers use different user IDs to serve the responses.
5586 This change moves to using socketpair instead of an AF_UNIX socket.
5589 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5590 It can't seem to pass between child processes yet, but I think we
5591 are closer now than before. This moves us back to using Unix
5592 Domain Sockets. [Ryan Bloom]
5594 *) libapr functions and types renamed with apr_ prefix.
5595 #include "apr_compat.h" for 1.3.x backwards compat
5598 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5599 return the right information on the local socket address.
5600 [Gregory Nicholls <gnicholls level8.com>]
5602 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5603 [Gregory Nicholls <gnicholls level8.com>]
5605 *) Add an option to not detach from the controlling terminal without
5606 going into single process mode. This allows for much easier
5607 debugging of the process startup code. [Ryan Bloom]
5609 *) ab: don't use perror() to report the failure of an APR function.
5612 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5613 scoreboard on graceful restarts.
5616 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5617 An invalid ap_proc_t was passed to ap_create_process().
5620 *) Allow modules to register filters. Those filters are still
5621 never called, but this is a step in the right direction.
5622 [Ryan Bloom and Greg Stein]
5624 *) Register the mod_cgid daemon process for cleanup so that it is
5625 killed at termination if it does not die when the parent gets
5626 SIGTERM. This change is to fix occasional problems where the
5627 process stays around. Bugs in similar logic in mod_rewrite and
5628 mod_include were also fixed. [Jeff Trawick]
5630 *) Fix a bug in the time handling. Basically, we were imploding a time
5631 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5632 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5633 uses those two fields to adjust the time value. Because of the HTTP
5634 spec, both of those values can be zero'ed out safely. This fixes
5635 the bug correctly. [Ryan Bloom]
5637 *) Fix a couple of place in the Windows code where the wrong error
5638 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
5640 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5642 *) Added the APR_EOL_STR macro for platform dependent differences in
5643 logfiles and other raw text (such as all APR files). Fixes logfiles
5644 not terminated with cr/lf sequences in Win32. [William Rowe]
5646 *) Move all strings functions in APR to src/lib/apr/strings and create
5647 apr_strings.h for the prototypes. [Ryan Bloom]
5649 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5650 to repeat the syscall until we stop getting EINTR. I noticed a
5651 related problem at termination (SIGTERM) on FreeBSD when using
5652 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5653 implementation work properly with child init. Previously, ap_lock()
5654 was essentially a no-op because all children were using different
5655 locks and thus nobody ever blocked. [Jeff Trawick]
5657 *) The htdocs/ tree has been moved out of the CVS source tree into
5658 a separate area for easier development. This has NO EFFECT on
5659 end-users or Apache installations. [Ken Coar]
5661 *) Integrate the mod_dav module for WebDAV protocol handling. This
5662 adds the dav and dav_fs modules, the SDBM library, and additional
5663 XML handling utilities. [Greg Stein]
5665 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
5668 *) Update the lib/expat-lite/ library (bring forward changes from
5669 the Apache 1.3 repository). [Greg Stein]
5671 *) If sizeof(long long) == sizeof(long), then prefer long in APR
5672 configure.in. [Dave Hill <ddhill zk3.dec.com>]
5674 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
5675 machines where sendfile is detected, but nobody has written ap_sendfile.
5676 [Dave Hill <ddhill zk3.dec.com>]
5678 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
5680 *) ab would start up more connections than needed, then quit when the
5681 desired number were finished. Also fixed a logic error involving
5682 ab keepalives. [Victor J. Orlikowski]
5684 *) WinNT: Implement non-blocking pipes with timeouts to communicate
5685 with CGIs. Apache 2.0a4 had non-blocking pipes but without
5686 timeouts (i.e, if a timeout was specified, the pipe reverted to
5687 a full blocking pipe). Now the behaviour is more in line with
5688 Unix non-blocking pipes.
5691 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
5692 cache open file handles along with accept socket reuse enables
5693 Apache 2.0 to serve non-keepalive requests for static files at
5694 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
5695 and Apache 2.0 will serve almost 1200 rps on my system).
5698 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
5699 supports two config directives, mmapfile (same behavious as
5700 mod_mmap_static) and cachefile. Use the cachefile directive
5701 to cache open file handles. This directive only works on systems
5702 that have implemented the ap_sendfile API. cachefile works today
5703 on Windows NT, but has not been tested on any flavors of Unix.
5706 *) Cleanup the configuration. With the last few changes the
5707 configuration process automatically:
5708 inherits information about how to build from APR. Allowing
5709 APR to inform Apache that it should or should not use -ldl
5711 Detects which mod_cgi should be used mod_cgi or mod_cgid,
5712 based on the threading model
5714 Apache calls APR's configure process before finishing it's
5715 configuration processing, allowing for more information flow
5720 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
5721 with non-zero argument makes the socket non-blocking. BeOS and
5722 OS/2 already worked this way. [Jeff Trawick]
5724 *) ap_close() now calls ap_flush() for buffered files, so write
5725 operations work a whole lot better on buffered files.
5728 *) Fix error messages issued from MPMs which explain where to change
5729 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
5732 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
5733 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
5734 now the way that the blocking state of a pipe is manipulated.
5735 ap_block_pipe() is gone. [Jeff Trawick]
5737 *) Correct the problem where the only local host name that the IP stack
5738 can discover are 'undotted' private names. If no fully qualified
5739 domain name can be identified, the default ServerName will be set to
5740 the machine's IP address string. A warning is always provided if the
5741 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
5743 *) Repair problems with config file processing which caused segfault
5744 at init when virtual hosts were defined and which caused ServerName to
5745 be ignored when there was no valid DNS setup. [Jeff Trawick]
5747 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
5749 *) Add ap_sendfile implementation for AIX
5750 [Victor J. Orlikowski]
5752 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
5753 apr_network_io.h, and apr_thread_proc.h.
5754 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
5756 *) Bring the allocation and pool debugging code back into a working
5757 state. This will need to be tested as so far it's only been used on
5760 *) Change configuration command setup to be properly typesafe when in
5761 maintainer mode. Note that this requires a compiler that can initialise
5762 unions. [Ben Laurie]
5764 *) Turn on buffering for config file reads. Part of this was to
5765 repair buffered I/O support in Unix and implement buffered
5766 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
5768 *) Win32: Fix problem where UTC offset was not being set correctly
5769 in the access log. Problem reported on news group by Jerry Baker.
5772 *) Fix segfault when reporting this type of syntax error:
5773 "</container> without matching <container> section", where
5774 container is VirtualHost or Directory or whatever.
5777 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
5778 Prevent the source code for CGIs from being revealed when
5779 using mod_vhost_alias and the CGI directory is under the document root
5780 and a user makes a request like http://www.example.com//cgi-bin/cgi
5781 as reported in <news:960999105.344321 ernani.logica.co.uk>
5784 *) Add support for the new Beos NetwOrking Environment (BONE)
5787 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
5788 final input char is incomplete; ap_bwrite_xlate() now handles
5789 incomplete final input chars. [Jeff Trawick]
5791 *) Yet another update to saferead/halfduplex stuff -- need to ensure
5792 that a bhalfduplex call occurs before logging or else DNS and
5793 such can delay the last packet of the response. [Dean Gaudet]
5795 *) Some syscall reduction in APR on unix -- don't seek when setting
5796 up an mmap; and don't fcntl() more than once per socket.
5799 *) When mod_cgid is started as root, the cgi daemon now switches
5800 to the configured User/Group (like other httpd processes)
5801 instead of continuing as root. [Jeff Trawick]
5803 *) The prefork MPM now uses an APR lock for the accept() mutex.
5804 It has not been getting a lock at all recently. httpd -V now
5805 displays APR's selection of the lock mechanism instead of the
5806 symbols previously respected by prefork. [Jeff Trawick]
5808 *) Change the mmap() feature test to check only for existence.
5809 The previous check required features not used by Apache.
5812 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
5813 sometimes mangled. The len parm to accept() was not
5814 initialized, leading sometimes to an endless loop of failed
5815 accept() calls on OS/390 and anywhere else that failed the call
5816 if the len was negative. Use <sys/un.h> for struct sockaddr_un
5817 instead of declaring it ourselves to fix a compilation problem
5818 on Solaris. [Jeff Trawick]
5820 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
5822 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
5824 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
5826 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
5827 initialization if ALLOC_DEBUG is defined; no known symptom
5828 otherwise. [Jeff Trawick]
5830 *) Fix typo in configure script when checking for mod_so. bash
5831 doesn't seem to have a problem but /bin/sh on Solaris does.
5832 Symptom: "./configure: test: unknown operator =="
5835 *) Rebind the Win32 NT and 9x services control into the MPM.
5836 All console, WinNT SCM and Win9x pseudo-service control code is
5837 now wrapped within the WinNT MPM.
5840 *) Make a copy of getenv("PATH") before storing for later use. Some
5841 getenv() implementations use the same storage for successive calls.
5842 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
5844 *) Server Tokens work in 2.0 again. This also propogates the change
5845 to allow just the product name in the server string using
5849 Changes with Apache 2.0a4
5851 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
5852 won't need to call it. [Greg Ames, Jeff Trawick]
5854 *) Move pre_config hook call to between configuration read and config
5855 tree walk. This allows all modules to implement pre_config hooks
5856 and know that they will be called at an appropriate time.
5859 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
5862 *) Add pre-config hooks back to all modules.
5865 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
5866 ContentDigest enabled and we can't/don't mmap the file.
5869 *) We now report the correct line number for syntax errors in config
5870 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
5872 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
5873 related bugs, and changed shmem/locking to use apr API. Shared-mem
5874 is currently disabled, however, because of problems with graceful
5875 restarts. [Ronald Tschalär]
5877 *) Fix corruption of IFS variable in --with-module= handling.
5878 Depending on the user's shell or customization thereof, there
5879 would be errors generating ap_config_auto.h later in the configure
5880 procedure. [Jeff Trawick]
5882 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
5883 isn't used (as in 1.3), except that on Unix it is now logged via
5884 ap_log_rerror() instead of by the child having STDERR_FILENO refer
5885 to the error log. [Greg Ames, Jeff Trawick]
5887 *) Add '-D' argument processing for run time configuration defines.
5890 *) Organize http_main.c as independent code, such that no code or
5891 global data is exported from it. WIN32 will dynamically link it
5892 to the server core, so this will prevent mutual dependency.
5895 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
5896 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
5899 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
5900 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
5902 *) Add mod_charset_lite for configuring character set translation.
5905 *) Add '-n' option to htpasswd to make it print its user:pw record
5906 on stdout rather than having to frob a text file. [Ken Coar]
5908 *) Fix saferead. Basically, we flush the output buffer if a read on the
5912 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
5913 a conversion is single-byte only. [Jeff Trawick]
5915 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
5916 the BeOS 5.0 documentation says that shutdown doesn't work yet.
5919 *) Fix some minor errors where pid was being manipulated as an int
5920 instead of the portable pid_t. [Roy Fielding]
5922 *) Fix some error log prints that were printing the pointer to a
5923 structure rather than the pid within the structure.
5924 [Jeff Trawick, Roy Fielding]
5926 *) ab: Fix a command-line processing bug; track bad headers in
5927 err_response; support reading headers up to 2K.
5928 [Ask Bjoern Hansen <ask valueclick.com>]
5930 *) Fix ap_resolve_env() so that it handles new function added in a prior
5931 alpha (see "Added the capability to do ${ENVVAR} constructs in the
5932 config file.") as well as the constructs used by mod_rewrite.
5933 [Paul Reder <rederpj raleigh.ibm.com>]
5935 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
5937 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
5938 APR to perform translation, instead of accessing the hard-coded tables
5939 in 1.3's ebcdic.c. [Jeff Trawick]
5941 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
5944 *) Add the ability to hook into the config file reading phase. Basically
5945 if a directive is specified EXEC_ON_READ, then when that directive is
5946 read from the config file, the assocaited function is executed. This
5947 should only be used for those directives that must muck with HOW the
5948 server INTERPRETS the config. This should not be used for directives
5949 that re-order or replace items in the config tree. Those changes should
5950 be made in the pre-config step.
5953 *) Add mod_example to the build system.
5956 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
5957 byte character sets. [Jeff Trawick]
5959 *) Pick up various EBCDIC fixes from 1.3 (from Martin
5960 Kraemer and Oliver Reh originally according to the change log).
5963 *) Fix a couple of problems in RFC1413 support (controlled by the
5964 IdentityCheck directive). Apache did not build the request string
5965 properly and more importantly Apache would loop forever if the
5966 would-be ident server dropped the connection before sending a
5967 properly terminated response. [Jeff Trawick]
5969 *) apxs works in 2.0.
5972 *) Reliable piped logs work in 2.0.
5975 *) Introduce a hash table implementation into APR to be used for
5976 replacing tables and other random data structures in Apache.
5979 *) Add some more error reporting to htpasswd in the case of problems
5980 generating or accessing the temporary file. Also, pass in a
5981 buffer if the implementation knows how to use it (i.e., if L_tmpnam
5982 is defined). [Ken Coar]
5984 *) Configure creates config.nice now containing your configure
5985 options. Syntax: ./config.nice [--more-options]
5988 *) Fix various return code problems in APR on Win32. For most of
5989 these, APR was returning APR_EEXIST instead of GetLastError()/
5990 WSAGetLastError(). [Jeff Trawick]
5992 *) Make piped logs work again in version 2.0
5995 *) Add VPATH support to UNIX build system of Apache and APR.
5998 *) Fix ap_tokenize_to_argv to respect the const arguments that are
6002 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
6003 Patch submitted to author.
6006 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
6007 /sbin in PATH on FreeBSD (all submitted to rse previously)
6010 *) Fix building Pthread-based MPMs on OpenBSD
6011 [Sascha Schumann] PR#26
6013 *) Fix ap_readdir() problem on systems where d_name[] field in
6014 struct dirent is declared with only one byte. (This problem only
6015 affected multithreaded builds.) This caused a segfault during
6016 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
6017 least). [Jeff Trawick]
6019 *) Fix some make-portability problems on at least Tru64, Irix
6021 [Sascha Schumann] PR#18, PR#39
6023 *) Add ap_sigwait() to support old-style sigwait() on systems
6024 like OS/390 and UnixWare.
6027 *) Add POSIX-thread flags for more platforms.
6030 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
6031 (on Unix, at least) to handle resolver errors. Fix a bug in
6032 the definition of APR_ENOMEM so that ap_strerror() can spit
6033 out the correct error message for it.
6036 Changes with Apache 2.0a3
6038 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
6041 *) API: *HOOK* macros now have an AP_ prefix
6044 *) Win32: Eliminate redundant calls to initialize winsock.
6045 [Tim Costello <timcostello ozemail.com.au>]
6047 *) Fix bugs initializing ungetchar for pipes.
6048 [Chia-liang Kao <clkao CirX.ORG>]
6050 *) The ab program in the src/support directory is now portable using
6054 *) Support directory is being compiled when the server is built
6057 *) The configure option --with-program-name has been added to allow
6058 developers to rename the executable at configure time. This also
6059 changes the name of the config files to match the executable's name.
6062 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
6063 containing version numbers. [Martin Pool]
6065 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
6066 Unix; access_log and error_log now created with these perms; non-
6067 Unix is unaffected [Jeff Trawick]
6069 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
6070 Replaced more magic numbers with MD5_DIGESTSIZE.
6071 [William Rowe, Roy Fielding]
6073 *) Win32: Get mod_auth_digest compiling and added to the Windows
6074 build environment. Not tested and I'd be suprised if it
6075 actually works. [Bill Stoddard]
6077 *) Revamp the Win32 make environment. Makefiles have been removed and
6078 Apache.dsw created to bring together all the pieces. Create new file
6079 os/win32/BaseAddr.ref to define module base addresses (to prevent
6080 dll relocation at start-up).
6081 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
6083 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
6084 of the \015, \012, and \015\012 constants with macros.
6087 *) Add ap_xlate_open() et al for translation of text between different
6088 character sets. The initial implementation requires iconv().
6091 *) More FAQs and answers from comp.infosystems.www.servers.unix.
6092 [Joshua Slive <slive finance.commerce.ubc.ca>]
6094 *) CGI output is being timed out now.
6097 *) Fix the problem with dieing quietly. dupfile now takes a pool which
6098 is used by the new apr file. There is no reason to create a new file
6099 with the same lifetime as the original file.
6102 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
6103 module base addresses. This will help shooting seg faults
6104 in the field. [William Rowe <wrowe lnd.com>]
6106 *) Update Apache on Windows documentation. Add new document
6107 describing how to compile Apache on Windows.
6108 [William Rowe <wrowe lnd.com>]
6110 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
6111 microseconds instead of seconds. Some storage leaks and other
6112 minor bugs in related code were fixed. [Jeff Trawick]
6114 *) Win32: First cut at getting mod_isapi working under 2.0
6115 [William Rowe <wrowe lnd.com>]
6117 *) First stab at getting mod_auth_digest working under 2.0
6118 quick change summary:
6119 - moved the random byte generation (ap_generate_random_bytes) into APR
6120 - now uses ap_time_t
6121 - compiles and runs on linux
6123 [Brian Martin <bmartin penguincomputing.com>]
6125 *) Win32: Move the space stripping of physical service names
6126 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
6127 unresolved symbol. Add dependency checking to the
6128 CreateService call to ensure TCPIP and AFP (winsock) is started
6130 [William Rowe <wrowe lnd.com>]
6132 *) Win32: Add code to perform latebinding on functions that may
6133 not exist on all levels of Windows where Apache runs. This
6134 is needed to allow Apache to start-up on Win95/98. All calls
6135 to non portable functions should be protected with
6136 ap_oslevel checks to prevent runtime segfaults.
6137 [William Rowe <wrowe lnd.com>]
6139 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
6141 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
6143 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
6144 This addresses PR 1623. Still need to address timing out runaway
6145 CGI scripts. [Bill Stoddard]
6147 *) Win32: Make ap_stat Windows 95/98 friendly
6148 [William Rowe <wrowe lnd.com>]
6150 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
6151 always fail. Need to initialise the dwOSVersionInfoSize member of the
6152 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
6155 The patch also enhances ap_get_oslevel (and the associated enum) to
6156 handle selected service packs for NT4, and adds recognition for
6157 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
6158 we can use ReadFileScatter and WriteFileGather in readwrite.c.
6159 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
6161 *) Get mod_rewrite building and running, and mod_status building for Win NT
6162 [Allan Edwards <ake raleigh.ibm.com>]
6164 *) Patch to port mod_auth_db to the 2.0 api and also to support
6165 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
6166 2.7.7. It should work with version 1 as well but I haven't tested it.
6167 [Brian Martin <bmartin penguincomputing.com>]
6169 *) Get APR DSO code working under Windows. Includes cross platform
6171 [<Tim.Costello BTFinancialgroup.com>]
6173 *) Fix some of the Windows APR time functions.
6176 *) FAQ changes related to tidying up historical documents on the web site.
6177 [Joshua Slive <slive finance.commerce.ubc.ca>]
6179 *) Move Windows DSO code into APR.
6182 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
6183 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
6184 at build time. At this point, the server will not compile on Windows because
6185 of the recent DSO commits. Fixing those next.
6186 [Bill Rowe & Bill Stoddard]
6188 *) Added error checking for file I/O APR routines.
6189 [Jon Travis <jtravis covalent.net>]
6191 *) APR: Don't use the values of resolver error codes for the
6192 corresponding APR error codes. On Unix and Win32, return the
6193 proper APR error code after a resolver error. [Jeff Trawick]
6195 Changes with Apache 2.0a2
6197 *) Renamed the executable back to httpd on all platforms other
6201 *) Allow BeOS to survive restarts, log properly and a few
6202 small things it had problems with due to the way it setup
6203 users and groups. [David Reid]
6205 *) Get mod_rewrite working with APR locks
6206 [Paul Reder <rederpj raleigh.ibm.com>]
6208 *) Actually remove the sempahore when the lock cleanup routine
6209 is called on BeOS. [David Reid]
6211 *) Clear hook registrations between reads of the config file.
6212 When DSOs are unloaded and re-loaded the old hook pointers may
6213 no longer be valid. This fix eliminates potential segfaults.
6214 [Allan Edwards <ake raleigh.ibm.com>]
6216 *) Fix a problem with Sigfunc not being defined or bypassed
6217 if sigaction() wasn't found. [Jim Jagielski]
6219 *) Fix the locking mechanism on BSD variants. They now use fcntl
6220 locks. This allows the server to start and serve pages.
6223 *) First cut at getting the Win32 installer to work
6224 [William Rowe <wrowe lnd.com>]
6226 *) Get htpasswd compiling under Windows
6227 [William Rowe <wrowe lnd.com>]
6229 *) Change the log message for a bind() failure to show the
6230 interface and port number. [Jeff Trawick]
6232 *) Import the documentation from 1.3.12 and bring parts of it
6233 up-to-date with respect to the changes that have occurred
6237 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
6238 now logged correctly on BeOS.
6241 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
6242 Makefile.win includes the same user interface as the old
6244 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
6246 *) Win32 exec now uses COMSPEC environment string for command
6247 shell path resolution.
6248 [William Rowe <wrowe lnd.com>] PR#3715
6250 *) Win32: ap_connect() was not returning correct error condition
6252 [Allen Prescott <allen clanprescott.com>]
6254 *) Win32: ap_open() was broken on Win9x because an NT-specific
6255 flag was passed to CreateFile. ap_puts() added an unnecessary
6257 [Jeff Trawick <trawick us.ibm.com>]
6259 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
6260 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
6261 confusing ee/et name and made all extensions language/dialect
6262 rather than country reflecting. Changed example files to
6263 explicit reflect the ISO charset and added a few common
6264 ones to the example config [dirkx]
6266 *) Extend external module capability. To use this, you call
6267 configure with --with-module=path/to/mod1,path/to/mod2,etc.
6270 *) Backported the various "default charset" fixes from 1.3.12,
6271 including the AddDefaultCharset directive. [Jim Jagielski]
6273 *) Added the capability to do ${ENVVAR} constructs in the
6274 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
6275 it does this on a line by line basis; i.e. if the envvar
6276 expands to something with spaces you have to protect it
6277 by adding quotes around it (Unless of course you expect it
6278 to contains more than one argument. Alternatively you
6279 can compile it on a per token basis; which is what people
6280 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
6281 hampers fancier hacks.
6282 [Dirk-Willem van Gulik]
6284 *) Changed the 'ErrorDocument' syntax in that it NO longer
6285 supports the asymetric
6287 ErrorDocument 301 "Some message
6289 Note the opening " quote, without a closing quote. It now
6290 has either the following syntaxes
6292 ErrorDocument XXX /local/uri
6293 ErrorDocument XXX http://valid/url
6294 ErrorDocument XXX "Some Message"
6296 The recognition heuristic is: if it has a space it
6297 is a message. If it has no spaces and starts with a /
6298 or is a valid URL then treat it that way. Otherwise it
6299 is assumed to be a message.
6301 This breaks backward compatibility but makes live a hell
6302 of a lot easier for GUI's and config file parsers.
6303 [Dirk-Willem van Gulik]
6305 *) Changed 'CacheNegotiatedDocs' from its present/not-present
6306 syntax into a 'on' or 'off' syntax. As it currently is the
6307 only non nesting token which uses NO_ARGS and thus is an
6308 absolute pain for any config interface automation. This
6309 breaks backward compatibility. [Dirk-Willem van Gulik]
6311 *) Add ability to add external modules to the build process. This is
6312 done with --with-module=/path/to/module. Modules can only be added
6313 as static modules at this point.
6316 Changes with Apache 2.0a1
6318 *) Fix FreeBSD 3.3 core dump.
6319 Basically, ap_initialize() needs to get called before
6320 create_process(), since create_process() passes op_on structure
6321 to semop() to get a lock, but op_on isn't initialized until
6322 ap_initialize() calls setup_lock(). Here is a slight
6323 rearrangement to main() which calls ap_initialize() earlier...
6324 [Jeff Trawick <trawick us.ibm.com>]
6326 *) Enable Apache to use sendfile/TransmitFile API
6327 [Bill Stoddard, David Reid, Paul Reder]
6329 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
6333 *) Make file I/O and network I/O writev/sendv APIs consistent.
6334 Eliminate use of ap_iovec_t and use Posix struct iovec.
6335 Use seperate variable on ap_writev to set the number of iovecs
6336 passed in and number of bytes written.
6339 *) Adapt file iol to use APR functions. Replaced ap_open_file()
6340 with ap_create_file_iol(). ap_create_file_iol() requires that
6341 the file be opened prior to the call using ap_open().
6344 *) Port mod_include and mod_cgi to 2.0
6345 [Paul Reder, Bill Stoddard]
6347 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
6348 bytes_read/bytes_written is always valid (never -1). Plus
6349 some fixes to buff.c to correct problems introduced by the
6350 errno => ap_status_t changes a while back. Plus a fix to
6351 chunked encoding introduced right at the beginning of 2.0.
6354 *) Revamped UNIX build system to use autoconf and libtool.
6355 [Manoj Kasichainula, Sascha Schumann]
6357 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
6359 *) SECURITY: More rigorous checking of Host: headers to fix security
6360 problems with mass name-based virtual hosting (whether using mod_rewrite
6361 or mod_vhost_alias).
6362 [Ben Hyde, Tony Finch]
6364 *) Add back support for UseCanonicalName in <Directory> containers.
6365 [Manoj Kasichainula]
6367 *) Added APLOG_STARTUP log type. This allows us to write an error
6368 message without any of the date and time information. As a part
6369 of this change, I also removed all of the calls to fprintf(stderr
6370 and replaced them with calls to ap_log_error using APLOG_STARTUP
6371 writing to stderr is no longer portable, because we don't direct
6372 stderr to the error log on all platforms.
6375 *) Convert error logging functions to take errno as an argument.
6376 This makes our error logs more portable, because some Windows API's
6377 don't set errno. This change allows us to still output a valid
6378 message on all of our platforms.
6381 *) mod_mime_magic runs in 2.0-dev now.
6382 [Paul Reder <rederpj raleigh.ibm.com>]
6384 *) sendfile has been added to APR.
6385 [John Zedlewski <zedlwski Princeton.EDU>]
6387 *) buff.c has been converted to no longer use errno.
6388 [Manoj Kasichainula]
6390 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
6391 interface adaption to APR functions did it. [Martin Kraemer]
6393 *) Support DSOs properly on 32-bit HP-UX 11.0
6394 [Dilip Khandekar <dilip cup.hp.com>]
6396 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
6397 [Ralf S. Engelschall]
6399 *) Cleaned APR build environment integration and bootstrap APR
6400 automatically for developers from src/Configure.
6401 [Ralf S. Engelschall]
6403 *) Fixed building of src/support/htpasswd.c
6404 [Ralf S. Engelschall]
6406 *) When generating the Location: header, mod_speling forgot
6407 to escape the spelling-fixed uri. (Forw-Port from 1.3)
6410 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
6412 *) Change all pools to APR contexts. This is the first step to
6413 incorporating APR into Apache. [Ryan Bloom]
6415 *) Move "handler not found" warning message to below the check
6416 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
6417 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
6419 *) Support line-continuation feature in config.option file and
6420 allow the loading of multiple option sections at once via
6421 ``--with-option=<section1>,<section2>,...''
6422 [Ralf S. Engelschall]
6424 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
6426 Changes with Apache MPM
6428 *) Use asynchronous AcceptEx() and a completion port to accept and
6429 dispatch connections to threads in Windows NT/2000.
6432 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
6435 *) Implement the APACI --with-option facility
6436 (per default used the config.option file).
6437 [Ralf S. Engelschall]
6439 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
6441 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
6442 Replace pre_connection module call with a register_hook call and
6443 implement pre_connection as a hook. The intent is that these hooks will
6444 be extended to allow Apache to be multi-protocol, and also to allow the
6445 calling order to be specified on a per-hook/per-module basis.
6448 *) Implement mpm_* methods as "modules". Each method gets its own
6449 subdir in src/modules (eg: src/modules/prefork). Selection
6450 of method uses Rule MPM_METHOD. [Jim Jagielski]
6452 *) Port the hybrid server from the apache-apr repository as
6453 mpm_mpmt_pthread. [Manoj Kasichainula]
6455 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
6456 amongst the unix MPMs.
6458 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
6459 signal handling for the new world order. [Dean Gaudet]
6461 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
6462 of alloc.c for now. [Dean Gaudet]
6464 *) Handle partial large writes correctly. [Ben Laurie]
6466 *) Eliminate conn_rec's pointer to server. All it knows is the base server
6467 based on IP/port. [Ben Laurie]
6469 *) Port a bunch of modules to the new module structure.
6470 ["Michael H. Voase" <mvoase midcoast.com.au>]
6472 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
6474 *) Basic restructuring to introduce the MPM concept; includes various
6475 changes to the module API... better described by
6476 docs/initial_blurb.txt. [Dean Gaudet]
6478 Changes with Apache pthreads
6480 *) New buff option added: BO_TIMEOUT. It describes the timeout for
6481 buff operations (generally over a network).
6482 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
6484 *) Created http_accept abstraction. Added 4 new functions (not exported):
6485 init_accept(), begin_accepting_requests(), get_request(),
6486 stop_accepting_requests() [Bill Stoddard]
6488 *) Fix to ap_rprintf call that allows mod_info to work properly.
6489 [James Morris <jmorris intercode.com.au>]
6491 *) user and ap_auth_type fields were moved from connection_rec to
6492 request_rec. [Ryan Bloom]
6494 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
6495 needed in a threaded server.
6497 *) Initial pthread implementation from from Dean's apache-nspr code.
6498 [Bill Stoddard, Ryan Bloom]
6501 Changes with Apache 1.3.9
6503 *) Remove bogus error message when a redirect doesn't set Location.
6504 Instead, use an empty string to avoid coredump if the error message
6505 was supposed to include a location. [Roy Fielding]
6507 *) Don't allow configure to include mod_auth_digest unless it is
6508 explicitly requested, even if the user asked for all modules.
6511 *) Translate module names to dll names for OS/2 so that they are no more
6512 than 8 characters long and have an extension of "dll" instead of "so".
6515 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
6516 Fix test-compile check to check for randbyte instead of trand32.
6517 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
6518 and tweak to make Amaya happier. [Ronald Tschalär]
6520 *) Ensure that the installed expat include files are world readable,
6521 just like the other header files. [Martin Kraemer]
6523 *) Fixed generated AddModule adjustments in APACI's `configure' script
6524 in order to allow (new) modules like mod_vhost_alias to be handled
6525 correctly (which was touched by the adjustments for mod_alias).
6526 [Ralf S. Engelschall]
6528 *) For binary builds, add -R flag to apachectl to work around the lack of
6529 an absolute path to the ./libexec directory where the libhttp.ep file
6530 is needed for SHARED_CORE architectures. [Randy Terbush]
6532 *) WIN32: Create the CGI script process as DETACHED. This may solve the
6533 problem observed by some Win95/98 users where they get CGI script
6534 output sent to the console. [Bill Stoddard]
6536 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
6537 routines are now called ap_base64* and are 'plain' (i.e., no
6538 pool access or anything clever). Inside util.c the routines acting
6539 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
6540 The oddly named ap_uuencode(), ap_uudecode() are kept around for
6541 now but deprecated. [dirkx]
6543 *) Clean up the base64 and SHA1 additions and make sure they are
6544 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
6545 files. [Roy Fielding]
6547 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
6548 checking. Allow compiling on VS 6.0. [Randy Terbush]
6550 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
6552 *) Use TestCompile to search for the truerand library (rather than blindly
6553 assuming its existence). If it is not found, complain (but do not
6554 exit - yet). [Martin Kraemer]
6556 *) We forgot to add the new exported function names to
6557 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
6559 *) Add description of -T command-line option to usage().
6560 [Ralf S. Engelschall]
6562 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
6563 searched only AFTER libap has been searched, because libap needs
6564 some symbols from libos. [Martin Kraemer]
6566 *) Fix conflict with original mod_digest related to the symbol of the
6567 module dispatch list (which has to be unique for DSO and follow the
6568 usual conventions for the installation procedure).
6569 [Ralf S. Engelschall]
6571 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6572 for other platforms as well. [Martin Kraemer]
6574 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6575 types by AP_LONG and replace reference to renamed variable 'ubuf'
6576 by 'buffer'. [Martin Kraemer]
6578 Changes with Apache 1.3.8 [not released]
6580 *) Flush the output buffer immediately after sending an error or redirect
6581 response, since the result may be needed by the client to abort a
6582 long data transfer or restart a series of pipelined requests.
6583 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
6585 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6586 [Ian Turner <iant sequent.com>] PR#4735
6588 *) Local struct mmap in http_core.c conflicted with system structure
6589 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6591 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6592 [Ronald Tschalär <ronald innovation.ch>]
6594 *) Fix a memory leak where the module counts were getting messed
6595 up across restarts. [David Harris <dharris drh.net>]
6597 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6598 properly in mod_access.
6599 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
6601 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6602 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
6604 *) PORT: Support for compaq/tandem/com.
6605 [Michael Ottati <michael.ottati compaq.com>, dirkx]
6607 *) Added SHA1 password encryption support to easy migration from
6608 Netscape servers. See support/SHA1 for more information.
6609 Caused the separation of ap_md5.c into md5, sha1 and a general
6610 ap_checkpass.c with just a validate_passwd routine. Added a
6611 couple of flags to support/htpasswd. Some reuse of the to64()
6612 function; hence renamed to ap_to64().
6613 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
6615 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6616 with ASCII/EBCDIC conversions in "ident" query.
6617 [David McCreedy <McCreedy us.ibm.com>]
6619 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6620 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6621 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6623 *) Fix SIGSEGV on some systems because the Vary fix below included
6624 a call to table_do with a variable argument list that was not
6625 NULL terminated. Replaced with better implementation. [Roy Fielding]
6627 Changes with Apache 1.3.7 [not released]
6629 *) The "Vary" response header field is now sanitised right before
6630 the header is sent back to the client. Multiple "Vary" fields
6631 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6632 "Vary: host, negotiate, host, accept-language") are reduced to
6633 single instances. This is a better solution than the force-no-vary
6634 one (which is still valid for clients that can't cope with Vary
6635 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6637 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
6639 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6640 least on Linux and FreeBSD for now.
6643 *) Win32: More apache -k restart work. Restarts are now honored
6644 immediately and connections in the listen queue are -not- lost.
6645 This is made possible by the use of the WSADuplicateSocket()
6646 call. The listeners are opened in the parent, duplicated, then
6647 the duplicates are passed to the child. The original listen sockets
6648 are not closed by the parent across a restart, thus the listen queue
6650 [Bill Stoddard <stoddard raleigh.ibm.com>]
6652 *) Fix handling of case when a client has sent "Expect: 100-continue"
6653 and we are going to respond with an error, but get stuck waiting to
6654 discard the body in the pointless hope of preserving the connection.
6655 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
6657 *) Fix 'configure' to work correctly with SysV-based versions of
6658 'tr' (consistent with Configure's use as well). [Jim Jagielski]
6660 *) apxs: Add "-S var=val" option which allows for override of CFG_*
6661 built-in values. Add "-e" option which works like -i but doesn't
6662 install the DSO; useful for editing httpd.conf with apxs. Fix
6663 editing code so that multiple invocations of apxs -a will not
6664 create duplicate LoadModule/AddModule entries; apxs can now be
6665 used to re- enable/disable a module. [Wilfredo Sanchez]
6667 *) Win32: Update the server to use Winsock 2. Specifically, link with
6668 ws2_32.lib rather than wsock32.lib. This gives us access to
6669 WSADuplcateSocket() in addition to some other enhanced comm APIs.
6670 Win 95 users may need to update their TCP/IP stack to pick up
6671 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
6672 [Bill Stoddard <stoddard raleigh.ibm.com>]
6674 *) Win32: Redirect CGI script stderr (script debug info) into the
6675 error.log when CGI scripts fail. This makes Apache on Win32
6676 behave more like Unix.
6677 [Bill Stoddard <stoddard raleigh.ibm.com>]
6679 *) Fixed `httpd' usage display: -D was missing.
6680 [Ralf S. Engelschall] PR#4614
6682 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
6683 [Ralf S. Engelschall] PR#4561, PR#4562
6685 *) OS/2: Fix problem with accept lock semaphores where server would die with
6686 "OS2SEM: Error 105 getting accept lock. Exiting!"
6687 [Brian Havard] PR#4505
6689 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
6690 [Randy Terbush <randy covalent.net>]
6692 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
6693 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
6695 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
6696 command potentially _is_ GCC. [Ralf S. Engelschall]
6698 *) Fix apxs build issues on AIX
6699 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
6701 *) DocumentRoot Checking: Under previous versions, when Apache
6702 first started up, it used to do a stat of each DocumentRoot to
6703 see if it existed and was a directory. If not, then an error
6704 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
6705 does not exist, you will get error messages in error_log. If
6706 the '-t' command line option is used (to check the configuration)
6707 the check of DocumentRoot IS performed. An additional command
6708 line option, '-T', has been added if you want to avoid the
6709 DocumentRoot check even when checking the configuration.
6712 *) Win32: The query switch "apache -S" didn't exit after showing the
6713 vhost settings. That was inconsistent with the other query functions.
6714 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
6716 *) Win32: Changed behaviour of apache -k restart.
6717 Previously, the server would drain all connections in the stack's
6718 listen queue before honoring the restart. On a busy server, this
6719 could take hours. Now, a restart is honored almost immediately.
6720 All connections in Apache's queues are handled but connections in
6721 the stack's listen queue are discarded. Restart triggered by
6722 MaxRequestPerChild is unchanged.
6723 [Bill Stoddard <stoddard raleigh.ibm.com>]
6725 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
6726 the accept loop. Good for a 5% performance boost. Cleaned up
6727 parent/child process management code.
6728 [Bill Stoddard <stoddard raleigh.ibm.com>]
6730 *) Added ceiling on file size for memory mapped files.
6731 [John Giannandrea <jg meer.net>] PR#4122
6733 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
6734 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
6735 [Henri Gomez <gomez slib.fr>, Ralf S. Engelschall]
6737 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
6738 use this at least for Expat. [Ralf S. Engelschall]
6740 *) Allow .module files to specify libraries with Lib:.
6743 *) Allow SetEnvIf[NoCase] to test environment variables as well
6744 as header fields and request attributes. [Ken Coar]
6746 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
6747 content-types are "text/html;parameters". PR#4524 [Ken Coar]
6749 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
6750 never accepted into any standard, and it opens up certain DoS
6751 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
6753 *) TestCompile updated. We can now run programs and output the
6754 results during the Configure process. [ Jim Jagielski]
6756 *) The source is now quad (long long) aware as needed. Specifically,
6757 the Configure process determines the correct size of off_t and
6758 *void. When the OS/platform/compiler supports quads, ap_snprintf()
6759 provides for the 'q' format qualifier (if quads are not available,
6760 'q' is silently "demoted" to long). [Jim Jagielski]
6762 *) When the username or password fed to htpasswd is too long, include the
6763 size limit in the error message. Also report illegal characters
6764 (currently only ':') in the username. Add the size restrictions
6765 to the man page. [Ken Coar]
6767 *) Fixed the configure --without-support option so it doesn't result in
6768 an infinite loop. [Marc Slemko]
6770 *) Piped error logs could cause a segfault if an error occured
6771 during configuration after a restart.
6772 [Aidan Cully <aidan panix.com>] PR#4456
6774 *) If a "Location" field was stored in r->err_headers_out rather
6775 than r->headers_out, redirect processing wouldn't find it and
6776 the server would core dump on ap_escape_html(NULL). Check both
6777 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
6778 if Location isn't set. [Doug MacEachern, Ken Coar]
6780 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
6781 of the Expat 1.0.2 distribution. [Greg Stein]
6783 *) Replace regexec() calls with calls to a new API stub function
6784 ap_regexec(). This solves problems with DSO modules which use the regex
6785 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]
6787 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
6788 environment variables can be set according to the protocol version
6789 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

6806 *) Support for server-parsed and multiview-determined ReadmeName and
6807 HeaderName files in mod_autoindex. Removed the restriction on
6808 "/"s in ReadmeName and HeaderName directives since the *sub_req*
6809 routines will deal with the access issues. (It's now possible to
6810 have {site|group|project|customer|...} wide readmes and headers.)

6821 handful of problems seen with mod_perl <Perl> configuration sections
6822 [Salvador Ortiz Garcia <sog msg.com.mx>]
6824 *) Mac OS and Mac OS X Server now use the appropriate custom layout
6825 by default when building with APACI; allow for platform-specific
6826 variable defaults in configure. [Wilfredo Sanchez]
6828 *) Do setgid() before initgroups() in http_main; some platforms
6829 zap the grouplist when setgid() is called. This was fixed in
6830 suexec earlier, but the main httpd code missed the change.

6846 being newer than Configuration so that it is less likely to fail
6847 when using APACI and shadow sources. [Wilfredo Sanchez]
6849 *) PORT: Add initial support for Mac OS (versions 10.0 and
6850 greater). Use Mac OS X Server layout for now. Clean up dyld code
6851 in unix/os.c, and don't install the dyld error handlers, which
6852 are no longer needed in Mac OS. [Wilfredo Sanchez]
6854 *) Rename Rhapsody layout to "Mac OS X Server". Change install
6855 locations to appropriate ones for user-built (as opposed to
6856 system) installs. [Wilfredo Sanchez]
6858 *) Modify mod_autoindex's handling of AddDescription so that the
6859 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
6861 *) Add functionality to the install-bindist.sh script created by
6862 binbuild.sh to use tar when copying distribution files to the
6863 serverroot. This allows upgrading an existing installation
6864 without nesting the new distribution in the old.
6866 install-bindist.sh now detects the local perl5 path to install
6867 apxs and dbmmanage with proper path to perl interpreter.
6869 Add an install-binsupport target which copies the source files
6870 for apxs and dbmmanage to bindist to allow these scripts to
6871 be properly installed relative to the destination serverroot.

6899 value of the DirectoryIndex directive is a single dot. Also likely
6900 to happen for anyother values of DirectoryIndex that will map back

6987 *) Correct an apparent typo: on the Windows and MPE platforms, the
6988 htpasswd utility was limiting passwords to only 8 characters.
6991 *) EBCDIC platforms: David submitted patches for two bugs in the
6992 MD5 digest port for EBCDIC machines:
6993 a) the htdigest utility overwrote the old contents of the digest file
6994 b) the Content-MD5 header value (ContentDigest directive) was wrong
6995 when the returned file was not converted from EBCDIC, but was a
6996 binary (e.g., image file) in the first place.
6997 [David McCreedy <mccreedy us.ibm.com>]
6999 *) support/htpasswd now permits the password to be specified on the
7000 command line with the '-b' switch. This is useful when passwords
7001 need to be maintained by scripts -- particularly in the Win32
7002 environment. [Ken Coar]
7004 *) Win32: Win32 multiple services patch. Added capability to install and
7005 run multiple copies of apache as individual services.
7008 apache -n apache1 -i -f c:/httpd.conf
7009 Installs apache as service 'apache1' and associates c:/httpd.conf

7035 mismatches were causing compilation problems with gcc -pedantic and
7036 in the TPF cross-compilation. [Ken Coar]
7038 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
7039 a roughly 5 fold speed up. [Brian Havard]
7041 *) proxy ftp: instead of using the hardwired string "text/plain" as
7042 a fallback type for files served by the ftp proxy, use the
7043 ap_default_type() function to determine the configured type.
7044 This allows for special configurations like
7045 <Directory proxy:ftp://some.host>
7046 DefaultType gargle/blurb
7048 Additionally, add the Content-Encoding: header to FTP proxy replies
7049 when the encoding is defined (by the AddEncoding directive).
7050 Because it was missing, it was almost impossible to browse compressed
7051 files using the FTP proxy (works now perfectly in Communicator).
7052 The ftp proxy now also returns the Date: and Server: header lines (if not
7053 much else... This code is "somewhat" broken) like normal requests do.
7056 *) Be more smart in APACI's configure script when determining the UID/GID
7057 for User/Group directives and use the determined UID/GID to initialize
7058 the permissions on the proxycachedir.
7059 [Dirk-Willem van Gulik, Ralf S. Engelschall]
7061 *) Changed the forking-prior-to-cleanup in the proxy module to first
7062 check wether it actually needs to collect garbage. This reduces
7063 the number of fork()s from one/request to just the odd one an hour.
7064 [Dirk-Willem van Gulik]

7093 *) M_INVALID needed a value within the scope of METHODS so that unknown
7094 methods can be access controlled. [Roy Fielding] PR#3821
7096 *) Added PassAllEnv; makes server's entire environment available
7097 to CGIs and SSIs executed within directive's scope. [Ken Coar]
7099 *) ap_uuencode() always added two trailing '='s and encoding of
7100 8 bit characters on a machine with signed char may produced
7101 incorrect results. Additionally ap_uuencode() should now
7102 work correctly on EBCDIC platforms.
7103 [Ronald Tschalär <ronald innovation.ch>] PR#3411
7105 *) WIN32: Binary installer now runs the configuration DLL before
7106 the reboot prompt (which is only given if MSVCRT.DLL system
7107 DLL is new or updated). This should avoid the configuration
7108 directory being empty after installation. [Paul Sutton]
7109 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

7113 the Apache service on NT. [Paul Sutton] PR#3741
7115 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
7117 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
7118 have been reported with flock() locking (probably related to kernel
7119 version). [Dean Gaudet] PR#2723, 3531

7132 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
7133 for 8-bit safeness. [Dean Gaudet]
7135 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
7136 because SPARCs have a small machine-specific maximum size for the Global
7137 Offset Table which is often exceeded when compiling one of the larger
7138 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977
7140 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

7160 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
7161 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
7162 possible buffer overflows. [Ralf S. Engelschall]
7164 *) Remove no longer used non-API function ap_single_module_init().
7165 [Ralf S. Engelschall]
7167 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
7170 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
7171 to make platform installations easier. [Wilfredo Sanchez]
7173 *) In configure, do not append the target name to the directory path if
7174 the path already contains "apache". [Ralf S. Engelschall]
7176 *) SIGPIPE is now ignored by the server core. The request write routines
7177 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
7178 correctly check for output errors and mark the connection as aborted.
7179 Replaced many direct (unchecked) calls to ap_b* routines with the
7180 analogous ap_r* calls. [Roy Fielding]
7182 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
7183 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
7184 Furthermore map lookups for non-existent keys are now cached as well.
7185 Additionally "txt" maps are now parsed with simple string functions
7186 instead of using ap_pregcomp(). As a side effect a bug that prevented
7187 the usage of keys containing the "," character was fixed.
7188 The changes drastically improve the performance when large rewrite maps
7190 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
7192 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
7193 other than GET, and const'd the definition of method in request_rec.
7196 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
7198 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
7199 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
7201 *) Add %V to mod_log_config, this logs the hostname according to the
7202 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
7203 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
7205 *) Add support for \n and \t to mod_log_config, can be used to produce
7206 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
7208 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
7210 *) Added informative error messages for failed munmap() and fseek() calls
7211 in http_core.c. [John Bley, Roy Fielding]
7213 *) Added some informative error messages for some failed malloc()
7214 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
7216 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
7217 is removed. This allows <Directory proxy:*> directives to work and
7218 prevents invalid requests from killing the process.
7219 [Brian Havard <brianh kheldar.apana.org.au>]
7221 *) Reorganised FAQ document.
7222 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497
7224 *) src/support/: The ApacheBench benchmark program was overhauled by
7225 David N. Welton: you can now have it generate an HTML TABLE, presumably
7226 for integration into other HTML sources. David updated the ab man page
7227 as well and added some missing descriptions. Thanks!
7228 [David N. Welton <davidw prosa.it>]
7230 *) Win32: The filename validity checker now allows filenames containing
7231 characters in the range 0x80 to 0xff (for example accented characters).
7232 [Paul Sutton] PR#3890
7234 *) Added conditional logging based upon environment variables to
7235 mod_log_config. mod_log_referer and mod_log_agent
7236 are now deprecated. [Ken Coar]
7238 *) Allow apache acting as a proxy server to relay the real
7239 reason of a failure to a client rather than the "internal
7240 server error" it does currently. The general exposure mechanism
7241 can be triggered by any module by setting the "verbose-error-to"
7242 note to "*"; this allows more than just proxy errors to be exposed.
7243 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
7245 *) Moved man pages for ab and apachectrl to section 8.
7246 [Wilfredo Sanchez, Roy Fielding]
7248 *) Added -S option to install.sh so that options can be passed to
7249 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
7251 *) Tweak modules Makefile generated by Configure so that it handles
7252 the test case of no modules being selected. [<chaz reliant.com>]
7254 *) Added a <LimitExcept method ...> sectioning directive that allows
7255 the user to assign authentication control to any HTTP method that
7256 is *not* given in the argument list; i.e., the logical negation
7257 of the <Limit> directive. This is particularly useful for controlling
7258 access on methods unknown to the Apache core, but perhaps known by
7259 some module or CGI script. [Roy Fielding, Tony Finch]
7261 *) Prevent apachectl from complaining if the PIDFILE exists but
7262 does not contain a process id, as might occur if the server is
7263 being rapidly restarted. [Wilfredo Sanchez]
7265 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
7267 *) Entity tag comparisons for If-Match and If-None-Match were not being
7268 performed correctly -- weak tags might cause false positives. Also,
7269 strong comparison wasn't properly enforced in all cases.
7270 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
7272 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
7275 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
7276 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
7278 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
7279 to util.c for parsing an HTTP header field value to extract the next
7280 list item, taking into account the possible presence of nested comments,
7281 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
7282 insignificant whitespace and lowercases non-quoted tokens.
7283 [Roy Fielding] PR#2065
7285 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
7286 code different from 500. This allows the proxy to, e.g., return
7287 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
7289 *) Fix ordering of language variants for the case where the traditional
7290 negotiation algorithm is being used with multiple language variants
7291 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
7293 *) Do not round the TCN quality calculation to 5 decimal places,
7294 unlike RFC 2296, because the calculation might need 12 decimal places
7295 to get the right result. [Roy Fielding]
7297 *) Remove unused code to disable transparent negotiation when
7298 negotiating on encoding only, as we now handle encoding too
7299 (though this is nonstandard for TCN), remove charset=ISO-8859-1
7300 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
7301 some debugging statements within mod_negotiation. [Koen Holtman]
7303 *) Fixed a rare memory corruption possibility in mod_dir if the index
7304 file is negotiable and no acceptable variant can be found.
7305 [Dean Gaudet, Roy Fielding, Martin Kraemer]
7307 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
7308 searching the Win32 registry for script interpreters.
7311 *) Win32: The compiled-in default filename for the error log is now
7312 error.log, which matches the default in the distributed httpd.conf.
7315 *) Win32: Any error messages from -i or -u command line options are now
7316 displayed on the console output rather than sent to the error log.
7317 Also the "Running Apache..." message is not output unless Apache is
7318 going to serve requests. [Paul Sutton]
7320 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
7321 and use a private significator ('$apr1$') to mark passwords as
7322 being smashed with our own algorithm. Also abstract the password
7323 checking into a new ap_validate_password() routine. [Ken Coar]
7325 *) Win32: The filename validity checker now allows "COM" but refuses
7326 access to "COM1" through "COM4". This allows filenames such
7327 as "com.name" to be served. [Paul Sutton] PR#3769.
7329 *) BS2000: Adapt to the new ufork() system call interface which will
7330 make subtasking easier on the OSD/POSIX mainframe environment.
7333 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
7334 ap_compat.h. [David White <david persimmon.com>] PR#3725
7336 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
7337 use `.db' instead of `.pag' not only for FreeBSD, but also when
7338 the NDBM library looks like Berkeley-DB based.
7339 [Ralf S. Engelschall] PR#3773

7342 [Ryan Bloom <rbb Raleigh.IBM.Com>]
7344 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
7346 *) SECURITY: Avoid some buffer overflow problems when escaping
7347 quoted strings. (This overflow was on the heap and we believe
7348 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
7350 *) Let src/Configure be aware of CFLAGS options starting with plus
7351 signs as it's the case for the HP/UX compiler.
7352 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
7354 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
7355 and check to see if the tar we wind up with supports '-h'.
7356 [Jim Jagielski] PR#3671
7358 *) A consistent and conservative style for all shell scripts has been
7359 implemented. Basically, all shell string tests use the traditional
7360 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
7361 to protect against bare null variable strings (ie: wrapping both
7362 sides with double quotes and prepending 'x'). 'x' was chosen
7363 because it's more universal and hopefully easier for old shell
7364 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
7367 *) The status module now prints out both the main server generation as
7368 well as the generation of each process. Also, the vhost info is
7369 printed with '?notable'. [Jim Jagielski]
7371 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
7372 and this makes its functions available to things in src/support.
7375 Changes with Apache 1.3.4
7377 *) Renamed macros status_drops_connection to ap_status_drops_connection
7378 and vestigial scan_script_header to ap_scan_script_header_err,
7379 mostly for aesthetic reasons. [Roy Fielding]
7381 *) The query switch "httpd -S" didn't exit after showing the
7382 vhost settings. That was inconsistent with the other query functions.
7385 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
7386 filename to the end of the STANDARD_MODULE_STUFF. Its
7387 presence at the beginning prevented reporting of the filename
7388 for modules compiled before 1 January 1999. [Ken Coar]
7390 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
7391 to detect and prevent access to special DOS device file names.
7392 [Paul Sutton, Ken Parzygnat]
7394 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
7395 and Makefile_win32_debug.txt (debug build) that work on Win95.
7396 Run each of the following from the src directory:
7397 nmake /f Makefile_win32.txt # compiles normal build
7398 nmake /f Makefile_win32.txt install # compiles and installs
7399 nmake /f Makefile_win32.txt clean # removes compiled junk
7400 nmake /f Makefile_win32_debug.txt # compiles debug build
7401 nmake /f Makefile_win32_debug.txt install
7402 nmake /f Makefile_win32_debug.txt clean
7405 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
7406 to build binary distributions. [Lars Eilebrecht]
7408 *) IndexOptions SuppressColumnSorting only turned off making
7409 the column headers anchors; you could still change the display
7410 order by manually adding a '?N=A' or similar query string to the
7411 URL. Now SuppressColumnSorting locks in the sort order so
7412 it can't be overridden this way. [Ken Coar]
7414 *) Added IndexOrderDefault directive to supply a default sort order
7415 for FancyIndexed directory listings. [Ken Coar] PR#1699
7417 *) Change the ap_assert macro to a variant that works on all platforms.
7418 [Richard Prinz <richard.prinz cso.net>] PR#2575
7420 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
7421 search for an underscore on dlsym() (as it's already the case
7422 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
7424 *) Small fix for mod_env.html: The module was documented as to be _not_
7425 compiled into Apache per default, although it _IS_ compiled into
7426 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
7428 *) Instead of fixing a bug in the generation procedure for config.status (a
7429 backslash was missing) we remove the bug together with it's complete
7430 context because the special cases of the past can now no longer occur
7431 because of the recent magic for the --with-layout default.
7432 [Ralf S. Engelschall] PR#3590
7434 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
7435 making sure the src/support/ tools are _forced_ to be build last (they
7436 depend on other libraries).
7437 [Markus Theissinger <markus.theissinger gmx.de>]
7439 *) Fix installation procedure: Now that os-inline.c is actually used (a
7440 recently fixed bug prevented this) we need to also install os-include.c
7441 in addition to os.h into the PREFIX/include/ location or building of
7442 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
7444 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
7445 allow us to distinguish between a garbled DSO (or even a file which isn't
7446 an Apache module DSO at all) and a DSO which doesn't match the current
7447 Apache API. [Ralf S. Engelschall] PR#3152
7449 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
7450 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
7451 match case insensitive (this especially avoids nasty patterns like
7452 `[tT][eE][sS][tT]'). Second two additional internal map functions
7453 `escape' and `unescape' were added which can be used to escape/unescape
7454 to/from hex-encodings in URLs parts (this is especially useful in
7455 combination with map lookups).
7456 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
7458 *) Renamed the macro escape_uri() to ap_escape_uri() which was
7459 forgotten (because it was a macro) in the symbol renaming process.
7460 [Ralf S. Engelschall]
7462 *) Fix some inconsistencies related to the scopes of directives. The only
7463 user visible change is that the directives `UseCanonicalName' and
7464 `ContentDigest' now use the (more correct) `Options' scope instead of
7465 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
7467 *) Using DSO, the Server token was being mangled. Specifically, the
7468 module's token was being added first before the Apache token. This
7469 has been fixed. [Jim Jagielski]
7471 *) Major overhaul of mod_negotiation.c, part 2.
7472 - properly handle "identity" within Accept-Encoding.
7473 - allow encoded variants in RVSA negotiation and let them appear in
7474 the Alternates field using the non-standard "encoding" tag-list.
7475 - fixed both negotiation algorithms so that an explicitly accepted
7476 encoding is preferred over no encoding if "identity" is not
7477 included within Accept-Encoding.
7478 - added ap_array_pstrcat() to alloc.c for efficient concatenation
7479 of large substring sequences.
7480 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
7483 *) Major overhaul of mod_negotiation.c, part 1.
7484 - cleanups to mod_negotiation comments and code structure
7485 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
7486 support for everything in the upcoming HTTP/1.1
7487 revision (draft-ietf-http-v11-spec-rev-06.txt).
7488 - language tag matching also handles tags with more than 2
7490 - empty Accept, Accept-Language, Accept-Charset headers are
7491 processed correctly; previously an empty header would make all
7492 values acceptable instead of unacceptable.
7493 - allowed for q values in Accept-Encoding
7494 - added support for transparent content negotiation (rfc2295 and
7495 rfc2296) (though we do not implement all features in these drafts,
7496 e.g. no feature negotiation). Removed old experimental version.
7497 - implemented 'structured entity tags' for better cache correctness
7498 (structured entity tags ensure that caches which can deal with Vary
7499 will (eventually) be updated if the set of variants on the server
7501 - this involved adding a vlist_validator element to request_rec
7502 - this involved adding the ap_make_etag() function to the global API
7503 - modified guessing of charsets used by Apache negotiation algorithm
7504 to guess 'no charset' if the variant is not a text/* type
7505 - added code to sort multiviews variants into a canonical order so that
7506 negotiation results are consistent across backup/restores and mirrors
7507 - removed possibility of a type map file resolving to another type map
7508 file as its best variant
7509 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
7511 *) RFC2396 allows the syntax http://host:/path (with no port number)
7512 but the proxy disallowed it (ap_proxy_canon_netloc()).
7513 [David Kristol <dmk bell-labs.com>] PR#3530
7515 *) When modules update/modify the file name in the configfile_t structure,
7516 syntax errors will report the updated name, not the original one.
7517 [Fabien Coelho <coelho cri.ensmp.fr>] PR#3573
7519 *) Correct some filename case assumptions from WIN32 to
7520 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
7522 *) For %v log ServerName regardless of the UseCanonicalName
7523 setting (similarly for %p). [Dean Gaudet]
7525 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
7526 rather late (too late for some invocations of TestCompile).
7527 This improves the make environment available to TestCompile and
7528 the *.module scripts. [Martin Kraemer]
7530 *) The hashbang emulation code in ap_execve.c would interpret
7531 #!/hashbang/scripts correctly, but failed to fall back to a
7532 standard shell for scripts which did NOT start with #!
7533 Now SHELL_PATH is started in these cases. [Martin Kraemer]
7535 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
7538 *) Update APXS manual page: some -q option arguments were missing
7539 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
7541 *) Cleanup the command line options: `-?' was documented to show
7542 the usage list but does it with an error because `?' is not a valid
7543 command. OTOH a lot of users expect `-h' to print such a usage list and
7544 instead are annoyed for ages by our huge unreadable list of directives.
7545 So we now changed the command line options this way:
7547 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
7548 very similar to the popular linker option.
7550 Intent: while -l gives the small list of modules, -L now gives the
7551 large list of directives implemented by these modules. This is also
7552 consistent with -v (short version info) and -V (large version info).
7554 Intent: it's now the expected option ;-)
7555 The manual page was adjusted accordingly.
7556 [Ralf S. Engelschall] PR#2714
7558 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
7559 wasn't defined. [Rick Franchuk <rickf transpect.net>]
7561 *) Removed recently introduced bugs and disfigurements in APACI:
7562 o fixed argument line processing: using $args was broken: It was not
7563 initialized and using args="$args $apc_option" and even args="$args
7564 \"$apc_option\"" fails in the second processing round for any arguments
7565 containing whitespaces. The only correct way is to use the construct
7566 "$@" (but not possible here) or iterate _both_ times over the implicit
7567 argument line (no argument to for-loop) which is what we now use.
7568 o make --with-layout=Apache the default without creating
7569 redundancy (copying the --with-layout block in the argument parsing
7570 loop). We achieve this by using the "$@" construct together with the
7571 `set' command to prepend --with-layout=Apache to the command line in
7572 case --with-layout is not used.
7573 o fixed auto-suffix handling now that config.layout exists.
7574 Paths which are auto-suffixed are marked with a trailing plus sign in
7575 config.layout and every path now can be marked this way (not only the
7576 four paths for which we do it currently). Additionally the suffix is
7577 no longer a static one. Instead it's now `/<target>' where <target> is
7578 the argument of the --target option or per default `httpd'.
7579 o allow also tabs (and only spaces) where we match whitespaces
7580 o various fixes and cleanups related to used shell coding style
7581 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7582 o trimmed output of --help to fit into 80 columns
7583 [Ralf S. Engelschall]
7585 *) Added two new core API functions, ap_single_module_configure() and
7586 ap_single_module_init(), which are now used by mod_so to configure a module
7587 after loading. [Ralf S. Engelschall]
7589 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
7590 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
7591 of ap_config.h to allow serialized accept for multiport listens.
7592 [Roy Fielding, Curt Sampson] PR#3120
7594 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
7595 of ap_config.h that would skip several defines if DEFAULT_GROUP
7596 was overridden. [Roy Fielding]
7598 *) PORT: The I86 version of DGUX has support for strncasecmp and
7599 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
7601 *) Fix ordering of definitions in ap_config.h so that ap_inline is
7602 defined before it might be used. [Victor Khimenko]
7604 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
7605 [Tom Serkowski <tks bsdi.com>] PR#3453
7607 *) Make generation of src/Configuration.apaci more robust: It failed to
7608 differenciate between modules when one module name was a postfix of
7609 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
7610 just XXX (think about totally non-standard names like "apache_ssl", too).
7611 [Ralf S. Engelschall] PR#3380
7613 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
7614 since 1.3b7) and make whitespace handling more robust (it failed horrible
7615 when whitespaces were present in the arguments of -D options).
7616 [Ralf S. Engelschall] PR#3240
7618 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
7619 creates an external package shadow tree in DIR before the local build
7620 shadow tree is generated under DIR. This way one can have the extracted
7621 Apache distribution tree read-only on NFS or CDROM and still build Apache
7622 from these sources. An automatically triggered VPATH-like mechanism is
7623 provided through the TOP variable, too.
7624 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez apple.com>]
7626 *) Fix negotiation so that a Vary response header is correctly
7627 generated when, for a particular dimension, variants only vary
7628 in having or not having a value for that dimension. [Paul Sutton]
7630 *) Fix negotiation so that we prefer an encoded variant over an
7631 unencoded variant if the user-agent explicitly says it can
7632 accept that encoding. Previously we always preferred the unencoded
7634 [Paul Ausbeck <paula alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
7636 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
7637 and the usage page was inconsistent with the functionality and manpage.
7638 [Ralf S. Engelschall]
7640 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
7641 They can occur multiple times and their arguments (`xxx') are passed AS
7642 IS to the compiler/linker command. [Ralf S. Engelschall]
7644 *) Fixed possible (but harmless in practice) bug in the DBM lookup
7645 procedure of mod_rewrite: very long keys were truncated.
7646 [Ralf S. Engelschall]
7648 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
7649 identifier, currently "Apache" and "GNU" are pre-defined in the file
7650 config.layout. Custom layouts are possible by using FILE:ID as the
7651 argument where the layout ID is taken from FILE.
7653 The config.layout file consists of <Layout ID>..</Layout> sections
7654 where inside those sections "path_variable: path_value" pairs can be
7655 specified. These lines are converted to path_variable='path_value'.
7657 *) Add a DefaultLanguage directive so that files missing a language
7658 extension (e.g., .fr, .de) can be labelled as being some other
7659 default language. DefaultLanguage can appear in <Directory> and
7660 <Files> containers as well as .htaccess files. [Paul Sutton]
7663 *) Fix TARGET configuration when configuring and installing using
7664 APACI configure. TARGET now defines the basename of the configuration
7665 file, startup script, manual page, etc. log_error_core() now reports
7666 the server binary name given by argv[0]. TARGET can now also be defined
7667 with --target=TARGET parameter passed to APACI configure.
7668 [Ralf Engelschall, Randy Terbush]
7670 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
7671 rather than OPT_INCLUDES [Rainer Schoepf <schoepf uni-mainz.de>]

7776 supported for the option argument: first BEGIN:foo which permutes module
7777 mod_foo with the begin of the module list, i.e. it `moves' the module to
7778 the begin of the list (gives it lowest priority). And second foo:END
7779 which permutes mod_foo with the end of the module list, i.e. it `moves'
7780 the module to the end of the list (gives it highest priority).

7783 *) Fix problem with 'apache -k shutdown' and startup event
7784 synchronisation (Win32). [Ken Parzygnat <kparz raleigh.ibm.com>]
7787 *) The config parser wasn't correctly noticing a missing '>'
7788 on container start lines (e.g., it wouldn't spot
7789 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom us.ibm.com>]
7792 *) Add a 'RemoveHandler' directive which will selectively remove
7793 all handler associations for the specified file extensions.
7794 [Ryan Bloom <rbbloom us.ibm.com>] PR#1799.
7796 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
7797 ResourceConfig directives on Win32. Also add a note to the effect
7798 of 'useless User directive ignored on Win32' to the errorlog if
7799 a User directive is encountered on Win32.
7800 [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2078, 2303.
7802 *) Fix multiple whitespace handling in imagemaps for mod_imap which was
7803 broken since Apache 1.3.1 where we took out compressing of multiple
7804 spaces in ap_cfg_getline().
7805 [Ivan Richwalski <ivan seppuku.net>] PR#3249
7807 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
7808 initialized correctly and the db_open() call used an invalid mode
7809 parameter. [Ron Klatchko <ron ckm.ucsf.edu>] PR#3171
7811 *) PORT: DSO support for UnixWare 7
7812 [Ralf S. Engelschall, Ron Record <rr sco.com>]
7814 *) Merge the contents of the {srm,access}.conf-dist* files into the
7815 httpd.conf-dist* files. The srm and access files now contain
7816 only comments, and httpd.conf has all the combined contents in
7817 a rational order. [Ken Coar]
7819 *) PORT: DSO/ELF support for FreeBSD 3.0.
7820 [Ralf S. Engelschall, Dirk Froemberg <ibex physik.TU-Berlin.DE>]
7822 *) Add a "default-handler" handler that calls the default_hander()
7823 function which is normally called for static content. This allows
7824 you to override a specific handler. [Marc Slemko]
7826 *) Further simplify checking for absolute paths by replacing an
7827 hard-coded syntax check with a call to a routine we already created to
7828 do this. [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2976, 3074
7830 *) Log an error if we encounter a malformed "require" directive
7831 in mod_auth if we know that we know that no other module can
7832 deal with it. [Marc Slemko]
7834 *) Remove ap_private_extern method of hiding conflicting symbols
7835 on the NEXT platform because it is not correct for all versions,
7836 and the versions for which it is correct are unknown.
7837 [Wilfredo Sanchez <wsanchez apple.com>]
7839 *) Fix inheritance of IndexOptions NameWidth and remove unintended
7840 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]

7843 is encountered in an .htaccess file somewhere down the tree.
7846 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
7848 *) Fixed a segmentation violation in mod_proxy when a response is
7849 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
7851 Changes with Apache 1.3.3
7853 *) Added a complete implementation of the Expect header field as
7854 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
7855 response when we already know the final status, which is mighty
7856 useful for PUT responses that result in 302 or 401. [Roy Fielding]
7858 *) Remove extra trailing whitespace from the getline results as part
7859 of the protocol processing, which is extra nice because it works
7860 between continuation lines, is almost no cost in the normal case
7861 of no extra whitespace, and saves memory. [Roy Fielding]
7863 *) Added new HTTP status codes and default response bodies from the
7864 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
7865 HTTP Extension Framework (510) specifications. Did not add the
7866 WebDAV 424 and 425 codes because they are bogus. We don't use any
7867 of these codes yet, but they are now available to 3rd-party modules.
7870 *) Fix a possible race condition between timed-out requests and the
7871 ap_bhalfduplex select that might result in an infinite loop on
7872 platforms that do not validate the descriptor. [Roy Fielding]
7874 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
7875 running Apache server [Paul Sutton]
7877 *) Fix mod_autoindex bug where directories got a size of "0k" instead
7878 of "-". [Martin Plechsmid <plechsmi karlin.mff.cuni.cz>, Marc Slemko]
7881 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker jetair.be>]
7883 *) Add the server signature text (from the core ServerSignature directive)
7884 to the list of envariables available to scripts, SSI, and the like.
7887 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
7888 [M. Laak <maert proinv.ee>] PR#3108
7890 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
7891 calculation in mod_status for all systems which don't have POSIX
7892 sysconf() (like UTS 2.1) and not only for the NEXT platform.
7893 [Dave Dykstra <dwd bell-labs.com>] PR#3055
7895 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
7896 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
7897 instead of ap_getword(..., ' ') (which parses only according to spaces
7898 but not tabs). [James Morris <jmorris intercode.com.au>,

7901 *) Fix the SERVER_NAME variable under sub-request situations (where
7902 `UseCanonicalName off' is used) like CGI's called from SSI pages or

7925 working directory to fill in some blanks. [Ken Parzygnat

7940 <steve.cameron compaq.com>]
7942 *) Reconstructed the loop through multiple htaccess file names so
7943 that missing files are not confused with unreadable files.
7946 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
7947 errno on an error, which leads to one error being mistaken for
7948 another when reading non-existent .htaccess files.
7951 *) OS/2: The new header tests get things right, need to update

7966 *) Avoid possible line overflow in Configure: Use an awkfile to

7969 Changes with Apache 1.3.2
7971 *) Fix bug in ap_remove_module(), which caused problems for dso's
7972 who were the top_module. [Doug MacEachern]
7974 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
7975 mod_auth_db to both be friendly to users who wants to use this version
7976 and to avoid problems under platforms where only version 2.x is present.
7977 [Dan Jacobowitz <drow false.org>, Ralf S. Engelschall]
7979 *) When using ap_log_rerror(), make the error message available to the
7980 *ERROR_NOTES envariables by default. [Ken Coar]
7982 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
7983 You now must define a BS2000Account name for the server User.
7984 This has fewer security implications than the old approach.
7987 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
7988 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
7989 platform to make the braindead HPUX linker happy. Notice, for the module
7990 DSOs we don't have to use this, because these are loaded manually (and
7991 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
7993 *) Remove 64 thread limit on Win32.
7994 [Bill Stoddard <stoddard raleigh.ibm.com>]
7996 *) Remove redundant substitutions in top-level Makefile.tmpl.
7997 [Ralf S. Engelschall]
7999 *) Fix APACI's `Group' configuration adjustment - especially for Linux
8000 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
8002 *) Make PrintPath work generically instead of having one version
8003 strictly for OS/2. [Jim Jagielski, Brian Havard]
8005 *) Fix the recently introduced C header file checking: We now use the C
8006 pre-processor pass only (and no longer the complete compiler pass) to
8007 determine whether a C header file exists or not. Because only this way
8008 we're safe against inter-header dependencies (which caused horrible
8009 portability problems). The only drawback is that we now have a CPP
8010 configuration variable which has to be determined first (we do a similar
8011 approach as GNU Autoconf does here). When all fails the user still has
8012 the possibility to override it manually via APACI or src/Configuration.
8013 As a fallback for the header check itself we can directly check the
8014 existance of the file under /usr/include, too.
8015 [Ralf S. Engelschall] PR#2777
8017 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
8018 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
8019 ap_private_extern defined to hide symbols that conflict with loaded
8020 dynamic libraries on the NEXT and RHAPSODY platforms.

8036 [Jeff Stewart <jws purdue.edu>] PR#2790
8038 *) Add some more LIBS for the SCO5 platform which are needed for the already
8039 used -lprot. It's actually a bug in SCO5, of course.
8040 [Ronald Record <rr sco.com>] PR#2533
8042 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
8043 trailing slash problem. [Jon Drukman <jsd gamespot.com>] PR#2933
8045 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
8046 platform, because it's only supported under version 4.0 and higher. But
8047 because our GuessOS is still unaware of Digital UNIX versions and the
8048 -msym is just to optimize the DSO statup time a little bit it's safe and
8049 best when we leave it out now. [Ralf S. Engelschall] PR#2969
8051 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
8052 functions: First all three functions no longer fail on strings containing
8053 "%" chars and second ap_log_printf() no longer does a double-formatting
8054 (instead it directly passes through the message to be formatted to the
8055 real internal formatting function). [Ralf S. Engelschall] PR#2941
8057 *) Allow "Include" directives anywhere in the server config
8058 files (but not .htaccess files). [Ken Coar] PR#2727
8060 *) The proxy was refusing to serve CONNECT requests except to
8061 port 443 (https://) and 563 (snews://). The new AllowCONNECT
8062 directive allows the configuration of the ports to which a
8063 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
8065 *) mod_expires will now act on content that is not sent from a file
8066 on disk. Previously it would never add an Expires: header to
8067 any response that did not come from a file on disk; the only
8068 case where it still doesn't (and can't) add one for that type of
8069 content is if you are using a modification date based setting.
8070 [Marc Slemko, Paul Phillips <paulp go2net.com>]
8072 *) Problems encountered during .htaccess parsing or CGI execution
8073 that lead to a "500 Server Error" condition now provide explanatory
8074 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
8077 *) Add NameWidth keyword to IndexOptions directive so that the
8078 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
8081 *) Recognize lowercase _and_ uppercase `uname' results under
8082 SCO OpenServer. [David Coelho <drc ppt.com>]
8084 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
8085 a common problem of (mis-administrated?) IIS servers, make the apache
8086 proxy immune to these errors (and ignore the duplicates, but log
8087 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
8089 *) The <IfModule and <IfDefine block starting directives now only
8090 allow exactly one argument. Previously, the optional negation
8091 character '!' could be separated by whitespace without a syntax
8092 error being reported, albeit defeating the IfModule functionality
8093 (enclosed directives would ALWAYS be executed). By using the
8094 stricter syntax, these hard-to-track errors can be avoided.
8097 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
8098 cause the standalone FancyIndexing directive to logically OR
8099 into any existing IndexOptions settings rather than wiping
8100 them out. [Ken Coar]
8102 *) Changes in ftp proxy: make URL parsing simpler by using the
8104 + Add display of the "current directory" in cases where it's
8105 different from the supplied path (e.g., ftp://user@host/ lives
8106 in /home/user, not in /, therefore clicking on "../" in the
8107 starting directory might send us to /home/).
8108 + When ftp login fails, (esp. when a user name was part of the
8109 URL already), we now return [401 Unauthorized ] to allow the
8110 browser to pop up an authorization dialog. This makes passwords
8111 slightly less visible (they don't appear in the regular log files)
8112 and implements a functionality that other www proxy servers
8116 *) Triggered by the recent "Via:" header changes, the proxy module would
8117 dump core for replies with invalid headers (e.g., duplicate
8118 "HTTP/1.0 200 OK" lines). These errors are now logged and the
8119 core dump is avoided. Also, broken replies are not cached.
8120 [Martin Kraemer] PR#2914
8122 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
8123 plop gmon.out profile data for each child [Doug MacEachern]
8125 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
8126 config.status script to be immune against arguments with whitespaces.
8127 [Yves Arrouye <yves apple.com>] PR#2866
8129 *) Replace the inlined information grabbing stuff for the configuration
8130 adjustment feature (no --without-confadjust) with calls to a new helper
8131 script `buildinfo.sh' which is both more flexible and already proofed to
8132 be more robust against platform differences. This mainly fixes the
8133 recently occured ``sed: command garbled: ...'' problems.
8134 [Ralf S. Engelschall] PR#2776, PR#2848
8136 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
8137 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
8138 without complains after we recently added the POST feature.
8139 [Ralf S. Engelschall]
8141 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
8142 modules as API functions and we forgot them at the big symbol renaming.
8143 [Ralf S. Engelschall]
8145 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
8146 [Youichirou Koga <y-koga jp.FreeBSD.ORG>] PR#2895
8148 *) Dynamically size the filename column of mod_autoindex output.
8151 *) Add the ability to do POST requests to the ab benchmarking tool.
8152 [Kurt Sussman <kls best.com>] PR#2871
8154 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
8155 5 to 10 because there are some users out there who always have 5 to 8
8156 variables in one RewriteRule and had to patch mod_rewrite.h for every
8157 release. So 15 should be now more than enough, even for them. (I never
8158 needed more than 4 in my RewriteRules ;-)
8159 [Ralf S. Engelschall]
8161 *) Make the proxy generate and understand Via: headers
8164 *) Change the proxy to use tables instead of array_headers for
8165 the header lines. [Martin Kraemer]
8167 *) Make sure the config.status file is not overridden when just
8168 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
8170 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
8171 provide a way to trace API changes that add functionality but do
8172 not create a compatibility issue for precompiled modules, etc.
8173 See include/ap_mmn.h for more details. [Randy Terbush]
8175 *) Fix suexec installation under `make install root=xxx' situation.
8176 [Ralf S. Engelschall]
8178 *) Extend the output of the -V switch to include the paths of all
8179 compiled-in configuration files, if they were overridden at
8180 compile time, for least astonishment of the user.
8183 *) When READing a request in ExtendedStatus mode, the "old"
8184 vhost, request and client information is not displayed.
8187 *) STATUS is no longer available. Full status information now
8188 run-time configurable using the ExtendedStatus directive.
8191 *) SECURITY [CAN-1999-1199] (cve.mitre.org):
8192 Eliminate O(n^2) space DoS attacks (and other O(n^2)
8193 cpu time attacks) in header parsing. Add ap_overlap_tables(),
8194 a function which can be used to perform bulk update operations
8195 on tables in a more efficient manner.
8198 *) SECURITY: Added compile-time and configurable limits for
8199 various aspects of reading a client request to avoid some simple
8200 denial of service attacks, including limits on maximum request-line
8201 size (LimitRequestLine), number of header fields (LimitRequestFields),
8202 and size of any one header field (LimitRequestFieldsize). Also added
8203 a configurable directive LimitRequestBody for limiting the size of the
8204 request message body. [Roy Fielding]
8206 *) Make status module aware of DNS and logging states, even if
8207 STATUS not defined. [Jim Jagielski]
8209 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
8211 *) Enhance mod_speling so that CheckSpelling can be used in
8212 <Directory> containers and .htaccess files. [Ken Coar]
8214 *) API: new ap_custom_response() function for hooking into the
8215 ErrorDocument mechanism at runtime [Doug MacEachern]
8217 *) API: new ap_uuencode() function [Doug MacEachern]
8219 *) API: scan_script_header_err_core() now "public" and renamed
8220 ap_scan_script_header_err_core() [Doug MacEachern]
8222 *) The 'status' module will now show the process pid's and their
8223 state even without full STATUS accounting. [Jim Jagielski]
8225 *) Restore the client IP address to the error log messages, this
8226 was lost during the transition from 1.2 to 1.3. Add a new
8227 function ap_log_rerror() which takes a request_rec * and
8228 formats it appropriately. [Dean Gaudet] PR#2661
8230 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
8231 whitespace in input lines -- including within quoted strings.
8233 but leading and trailing whitespace should continue to be
8234 stripped [Martin Kraemer]
8236 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
8237 the ugly use of an env. variable and use command-line args for
8238 alternate $PATH. Make more like advanced 'type's as well.
8241 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
8242 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
8243 <alain.st-denis ec.gc.ca>] PR#2736
8245 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
8247 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
8248 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
8249 directory was renamed to src/os/os2/ for consistency.
8250 [Brian Havard, Ralf S. Engelschall]
8252 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
8253 files (here modules) against other DSO files (here shared libraries).
8254 This is done by determining a subset of LIBS which can be safely used for
8255 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
8256 disabled for all platforms to avoid problems with this (experimental)
8257 rule. But we provide it now for those people how ran into problems and
8258 want to came out by forcing linking against DSOs.
8259 [Ralf S. Engelschall] PR#2587
8261 *) Fix suEXEC start message: Has to be of `notice' level to really get

8277 *) One more portability fix for APACI shadow tree support: Swap order of awk
8278 and sed in top-level configure script to avoid sed fails on some
8279 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the

8546 as <IfModule>..</IfModule> sections) which can be used to skip or process
8547 contained commands dependend of ``-D PARAMETER'' options on the command
8548 line. This can be used to achieve logical conditions like <IfDefine

8562 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
8563 in top-level configure script to avoid sed fails on some platforms (for

8565 output of Awk. [Bill Houle <bhoule sandiegoca.ncr.com>] PR#2435
8567 *) Improve performance of directory listings (mod_autoindex) by comparing
8568 integer keys (last-modified and size) as integers rather than converting
8569 them to strings first. Also use a set of explicit byte tests rather
8570 than strcmp() to check for parent directory-ness of an entry. Oh, and
8571 make sure the parent directory (if displayed) is *always* listed first
8572 regardless of the sort key. Overall performance winnage should be good
8573 in CPU time, instruction cache, and memory usage, particularly for large
8574 directories. [Ken Coar]
8576 *) Add a tiny but useful goody to APACI's configure script: The generation
8577 of a config.status script (as GNU Autoconf does) which remembers the used
8578 configure command and hence can be used to restore the configuration by
8579 just re-running this script or for remembering the configuration between
8581 [Ralf S. Engelschall]
8583 *) Add httpd -t (test) option for running configuration syntax tests only.
8584 If something is broken it complains and exits with a return code
8585 non-equal to 0. This can be used manually by the user to check the Apache
8586 configuration after editing and is also automatically used by apachectl
8587 on (graceful) restart command to make sure Apache doesn't die on restarts
8588 because of a configuration which is now broken since the last (re)start.
8589 This way `apachectl restart' can be used inside cronjobs without having
8590 to expect Apache to be falling down. Additionally the httpd -t can be run
8591 via `apachectl configtest'.

8745 proxy errors to be treated by ErrorDocument's as well. For this
8746 purpose, a new module-to-core communication variable "error-notes"
8747 was introduced; the proxy (and possibly other modules) communicates
8748 its error text using this variable. Its content is copied to a new
8749 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.

8779 [Ralf S. Engelschall]
8781 Changes with Apache 1.3b7
8783 *) Make sure a MIME-type can be forced via a RewriteRule even when no
8784 substitution takes place, for instance via the following rule:
8785 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
8786 requested by users in the past to force a single script without a .cgi
8787 extension and outside any cgi-bin dirs to be executed as a CGI program.
8788 [Ralf S. Engelschall] PR#2254
8790 *) A fix for protocol issues surrounding 400, 408, and
8791 414 responses. [Ed Korthof]
8793 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
8795 *) Fix discrepancy in proxy_ftp.c which was causing failures when
8796 trying to connect to certain ftpd's, such as anonftpd.
8797 [Rick Ohnemus <rick ecompcon.com>]
8799 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
8800 logfile instead of fiddling around itself with child spawning stuff.
8801 [Ralf S. Engelschall]
8803 *) Made RefererIgnore case-insensitive.
8805 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
8808 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
8809 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
8812 *) Improve RFC1413 support. [Bob Beck <beck bofh.ucs.ualberta.ca>]
8814 *) Fix support script `dbmmanage': It was unable to handle some sort
8815 of passwords, especially passwords with "0" chars.
8816 [Ralf S. Engelschall] PR#2242
8818 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
8819 [Ben Laurie] PR#2238
8821 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
8822 library), so CGI handling has been changed to use Win32 native handles
8823 instead of C file descriptors.
8824 [Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
8826 *) The proxy cache would store an incorrect content-length in the cached
8827 file copy after a cache update. That resulted in repeated fetching
8828 of the original copy instead of using the cached copy.
8829 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
8831 *) The Makefiles assumed that DSO files are build via $(LD). This
8832 is broken for two reasons: First we never defined at least LD=ld
8833 somewhere to make sure this works (it was silently assumed that most Make
8834 provide a built-in LD definition - ARGL!) and second using the generic LD
8835 variable is not the truth. Instead a special variable named LD_SHLIB is
8836 reasonable because although "ld" is usually the default, the command for
8837 building DSO files can be "libtool" or even "cc" on some systems.
8838 [Ralf S. Engelschall]
8840 *) Replace the AddVersionPlatform directive with ServerTokens which
8841 provides for more control over the format of the Server:
8842 header line. SERVER_SUBVERSION is no longer supported;
8843 all module should use the ap_add_version_component()
8844 API function instead. [Jim Jagielski]
8846 *) Support for the NCR MP/RAS 3.0
8847 [John Withers <withers semi.kcsc.mwr.irs.gov>]
8849 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
8850 not retrieved in src/Configure and thus was not useable.
8851 [Ralf S. Engelschall]
8853 *) Various Makefile consistency cleanups:
8854 - make OSDIR also automatically be relative to src/ like INCDIR
8855 - SUBDIRS is now generated in src/Makefile only and not in
8856 Makefile.config because it is a local define for this location.
8857 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
8858 any Makefile but make sure that at least the "-K inline" is kept in
8860 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
8861 - updated the dependencies theirself
8862 - removed not existing SHLIB variable from "clean" targets
8863 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
8864 already exists and OBJS_PIC are also just plain objects and have not
8865 directly to do with "shared" things. The only difference is that they
8866 contain PIC. So OBJS_PIC is the more canonical name.
8867 - Updated the Makefile-dependency lines for OBJS_PIC
8868 - Removed the Makefile-dependency line in Configure to avoid double
8870 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
8871 of xxx.lo as GNU libtool does with its PIC objects
8872 - reduce local complexity in modules Makefile.tmpl by moving the last
8873 existing target "depend" to the generation section in Configure, too.
8874 - removed the historical $(SPACER) which was used in the past together
8875 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
8876 is no longer needed.
8877 - force the build and run of the gen_xxx programs under main/ as the
8878 first step before building the objects because it looks cleaner
8879 [Ralf S. Engelschall]
8881 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
8884 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
8887 *) WIN32: Don't force ISAPI headers to finish with \n.
8888 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
8890 *) When opening "configuration" files (like httpd.conf, htaccess
8891 and htpasswd), Apache will not allow them to be non-/dev/null
8892 device files. This closes a DoS hole. At the same time,
8893 we use ap_pfopen to open these files to handle timeouts.
8894 [Jim Jagielski, Martin Kraemer]
8896 *) Apache will now log the reason its httpd children exit if they exit
8897 due to an unexpected signal. (It requires a new porting define,
8898 SYS_SIGLIST, which if defined should point to a list of text
8899 descriptions of the signals available. See PORTING.) [Dean Gaudet]
8901 *) WIN32: chdir() doesn't make sense in a multithreaded environment
8902 like WIN32. Before, Win32 CGI's could have had sporadic failures
8903 if a chdir call from one thread was made between another chdir call
8904 and a spawn in another thread. So, for now don't chdir for CGI scripts
8905 in WIN32. The current CGI "spec" is unclear as to whether it's
8906 necessary. Long-term fix is to either serialize the chdir/spawn combo
8907 or use WIN32 native calls to spawn a process. This temp fix was
8908 necessary to remove this as a showstopper for 1.3's release.
8911 *) Cleanup the suEXEC support in APACI and make it more safe:
8912 1. Add big fat hint in INSTALL about risks and to read the
8913 htdocs/manual/suexec.html document before using the suexec-related
8915 2. Make sure the user has at least provided one --suexec-xxxx option
8916 (specifies suEXEC parameters) in addition to --enable-suexec option.
8917 If only --enable-suexec is given APACI stops with a hint to INSTALL
8918 and htdocs/manual/suexec.html documents.
8919 3. Provide two additional --suexec-xxxx options to make the suEXEC
8920 configuration complete (especially for package maintainers who else
8921 had to patch the source tree) by providing ways to configure minimal
8922 UID/GID and safe PATH, too.
8923 [Ralf S. Engelschall]
8925 *) Cleanup of the `configure --shadow' process:
8926 - make sure the configure script creates its temporary files in the
8927 shadow tree to avoid conflicts with parallel configure runs
8928 - removed unnecessary option "-r" from "rm" call for Makefiles
8929 - make sure the configure scripts creates the shadow-wrapper Makefile
8930 only when no shadow trees already exists
8931 - make sure "make distclean" removes the shadow-wrapper Makefile but only
8932 when no more shadow trees exists
8933 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
8934 as fast (in the past it needed 70sec, now it runs just 38sec)
8935 - make sure CVS does not complain about the created files
8936 Makefille.<gnutriple> and directories src.<gnutriple>
8937 [Ralf S. Engelschall]
8939 *) Added the ap_add_version_component() API routine and the
8940 AddVersionPlatform core directive. The first allows modules to
8941 declare themselves in the Server response header field value,
8942 augmenting the SERVER_SUBVERSION define in the Configuration file
8943 with run-time settings (more useful in a loadable-module environment).
8944 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
8945 into the server version string. [Ken Coar] PR#2056
8947 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
8950 *) Emit the "Accept-Range" header for the default handler.
8951 [Brian Behlendorf] PR#1464
8953 *) Add a note to httpd.conf-dist that apache will on some systems fail
8954 to start when the Group # is set to a negative or large positive value.
8957 *) Make sure the module execution order is correct even when some modules
8958 are loaded under runtime (`LoadModule') via the DSO mechanism:
8959 1. The list of loaded modules is now a dynamically allocated one
8960 and not the original statically list from modules.c
8961 2. The loaded modules are now correctly setup by LoadModule for
8962 later use by the AddModule command.
8963 3. When the DSO mechanism for modules is used APACI's `install'
8964 target now enables all created `LoadModule' lines per default because
8965 this is both already expected by the user _and_ needed to avoid
8966 confusion with the next point and reduces the Makefile.tmpl complexity
8967 4. When the DSO mechanism for modules is used, APACI's `install'
8968 target now additionally makes sure the module list is reconstructed
8969 via a complete `ClearModuleList+AddModule...' entry.
8970 5. The support tool `apxs' now also makes sure an AddModule command
8971 is added in addition to the LoadModule command.
8972 6. The modules.c generation was extended to now contain two
8973 comments to make sure no one is confused by the confusing terminology
8974 of loading/linking (we use load=link+load & link=activate instead of
8975 the obvious load=activate & link=link :-( )
8976 This way now there is no longer a difference under execution time between
8977 statically and dynamically linked modules.
8978 [Ralf S. Engelschall]
8980 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
8981 Big Symbol Renaming. [Ralf S. Engelschall]
8983 *) Add a comment to mod_example.c showing the format of a FLAG command
8986 *) Standardized the time format in mod_status to match that of other
8987 places in the code (e.g. DATE_GMT). PR#1551
8989 *) Fix handling of %Z in timefmt strings for those platforms with no time
8990 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
8993 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
8994 feature compatible with 'UseCanonicalName off' by changing
8995 r->server->server_hostname to ap_get_server_name(). And I changed some
8996 functions which use r->server->port to use ap_get_server_port() instead,
8997 because if there's no Port directive in the config r->server->port is 0.
9000 *) get/set_module_config are trivial enough to be better off inline. Worth
9001 1.5% performance boost. [Dean Gaudet]
9003 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
9004 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
9007 *) [BS2000 security] BS2000 needs an extra authentication to initialize
9008 the task environment to the unprivileged User id. Otherwise CGI scripts
9009 would have a way to gain super user access. [Martin Kraemer]
9011 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
9012 absolute path, only log base name of logging source as is done
9013 in unix. [Martin Kraemer]
9015 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
9016 the encoding type from the Accept-Encoding header (if it's there)
9017 and use it in the response, as that's probably what it'll be expecting.
9018 [<Ronald.Tschalaer psi.ch>]
9020 *) Fix to mod_alias: translate_alias_redir is dealing with
9021 a URI, not a filename, so the check for drive letters for win32
9022 and emx is not necessary. [Dean Gaudet]
9024 *) WIN32: Allow .cmd as an executable extension.
9025 [Kari Likovuori <Kari.Likovuori mol.fi>] PR#2146
9027 *) Make Apache header files, and some variables, C++ friendly.
9028 [Michael Anderson's <mka redes.int.com.mx>]
9030 *) Child processes can now "signal" (by exiting with a status
9031 of APEXIT_CHILDFATAL) the parent process to abort and
9032 shutdown the server if the error in the child process was
9033 fatal enough. [Jim Jagielski]
9035 *) mod_autoindex's find_itme() was sensitive to MIME type case.
9036 [Jim Jagielski] PR#2112
9038 *) Make sure the referer_log and agent_log entries in the default httpd.conf
9039 file are also adjusted for the actual relative installation paths.
9040 [Ralf S. Engelschall] PR#2175
9042 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
9044 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
9047 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
9048 Additionally the checks for finding the vendor DSO library were moved
9049 from mod_so.c to Configure because first it needs $PLAT etc. and second
9050 mod_so already uses an abstraction layer and does not fiddle with the
9051 vendor functions itself.
9052 [Jens-Uwe Mager, Ralf S. Engelschall]
9054 *) PORT: Some optimization defines for NetBSD
9055 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
9057 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
9058 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
9060 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
9061 AIX variants should work fine, too. Even AIX 3.x should work). This is
9062 accomplished by using the free DSO emulation code from Jens-Uwe Mager
9063 which we put into a os/unix/os-dso-aix.c file.
9064 [Ralf S. Engelschall]
9066 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
9067 that we should use NET_SIZE_T == int but the include files force size_t.
9068 [Ralf S. Engelschall]
9070 *) Fix two bugs in select() handling in http_main.c.
9073 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
9074 is unset (as it is in situations like timeouts) where it is unclear
9075 whether errno is set or not. [Martin Kraemer]
9077 *) Just having APACI's localstatedir is too general and not enough for most
9078 of the systems. 1.3b6 again required manual APACI patches by package
9079 maintainers from Red Hat and FreeBSD because for their filesystem layout a
9080 little bit more flexibility in configuring the paths is needed. Hence we
9081 provide three additional configure options (--runtimedir, --logfiledir,
9082 --proxycachedir) which now can be used for more granular adjustments if
9083 --localstatedir is not enough to fit the particular needs. As a nice
9084 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
9085 [Ralf S. Engelschall]
9087 *) Make the install root for "make install" in APACI's Makefile overrideable
9088 by package authors. This way we are even more friendly to package
9089 maintainers (especially Debian and Red Hat) who build for the real prefix
9090 via "configure --prefix=/<real>" but use a different local prefix via
9091 "make root=/tmp/apache install" for rolling the package without bristling
9092 the target location on their system.
9093 [Ralf S. Engelschall]
9095 *) Workaround sed limitations in APACI's configure script by now
9096 substituting in chunks of 50 commands (because for instance HPUX's vendor
9097 sed has a limit of max. 98 commands)
9098 [Ralf S. Engelschall] PR#2136
9100 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
9101 [Ralf S. Engelschall] PR#2140
9103 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
9104 RENAMING process because they are defined as pre-processor macros instead
9105 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
9106 [Ralf S. Engelschall]
9108 *) Workaround braindead AWK's when generating ap_config.h: The split() and
9109 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
9110 [Ralf S. Engelschall] PR#2139
9112 *) Various bugfixes and cleanups for the APACI configure script:
9113 o fix IFS handling for _nested_ situation
9114 o fix Perl interpreter search: take first one found instead of last one
9115 o fix DSO consistency check
9116 o print error messages to stderr instead of stdout
9117 o add install-quiet for --shadow situation to Makefile stub
9118 o reduce complexity by avoiding sed-hacks for rule and module list loops
9119 [Ralf S. Engelschall]
9121 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
9123 *) Make sure the input field separator (IFS) shell variable is explicitly
9124 initialized correctly before _every_ `for' loop and also restored after
9125 the loops. [Ralf S. Engelschall]
9127 *) Make sure that "make install" doesn't overwrite the `mime.types' and
9128 `magic' files from an existing Apache installation. Because people often
9129 customize these for own MIME and content types.
9130 [Ralf S. Engelschall]
9132 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
9133 [Peter Galbavy, Ralf S. Engelschall] PR#2109
9135 *) Fix the path to the ScoreBoardFile in the install-config target, too.
9136 [Ralf S. Engelschall] PR#2105
9138 *) Let "configure" clear out the users parameters (provided as shell
9139 variables) to avoid side-effects in "src/Configure" when the user
9140 exported them (which is not needed, but some users do it).
9141 [Ralf S. Engelschall] PR#2101
9143 *) Provide backward compatibility from some old src/Configuration.tmpl
9144 parameter names to the canonical Autoconf-style shell variable names. For
9145 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
9146 but a hint message is displayed. [Ralf S. Engelschall]
9148 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
9149 CGI scripts from an existing Apache installation.
9150 [Ralf S. Engelschall, Jim Jagielski] PR#2084
9152 *) Make `configure --compat' more "compatible" by first
9153 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
9154 second by making sure the "avoid-bristling-suffix" /apache is not
9155 appended to sysconfdir, datadir, localstatedir and includedir when
9156 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
9158 *) NeXT required strdup() in support/logresolve.c
9159 [Francisco Tomei <fatomei sandburg.unm.edu>] PR#2082
9161 *) AIX required sys/select.h in support/ab.c
9162 [Jens Schleusener <Jens.Schleusener dlr.de>] PR#2081
9164 *) Fix the path to the MimeMagicFile in the install-config target, too.
9165 [Ralf S. Engelschall] PR#2089
9167 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
9169 *) If you start apache with the -S command line option it will dump
9170 out the parsed vhost settings. This is useful for folks trying
9171 to figure out what is wrong with their vhost configuration.
9172 (Other dumps may be added in the future.) [Dean Gaudet]
9174 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
9175 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
9178 *) Because /usr/local/apache is the default prefix the ``configure
9179 --compat'' option no longer has to set prefix, again. This way the
9180 --compat option honors a leading --prefix option. [Lars Eilebrecht]
9182 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
9183 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
9184 to avoid "discard const" warnings. [Ralf S. Engelschall]
9186 *) If a specific handler is set for a file yet the request still
9187 ends up being handled by the default handler, log an error
9188 message before handling it. This catches things such as trying
9189 to use SSIs without mod_include enabled. [Marc Slemko]
9191 *) Fix error logging for the startup case where ap_log_error() still uses
9192 stderr as the target. Now the default log level is honored here, too.
9193 [Ralf S. Engelschall]
9195 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
9196 long" errors when generating the MODULES entry for src/Makefile
9197 [Ben Hyde, Ralf S. Engelschall]
9199 *) Make sure src/Configure doesn't complain about the old directory
9200 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
9202 Changes with Apache 1.3b6
9204 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
9206 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
9207 interface via the similar but proprietary HP/UX shl_xxx-style system
9208 calls. [Ralf S. Engelschall]
9210 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
9211 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
9212 Make. [Ralf S. Engelschall]
9214 *) ++++ THE BIG SYMBOL RENAMING ++++
9215 To avoid symbol clashes with third-party code compiled into the server,
9216 we globally applied the prefix "ap_" to the following classes of
9218 - Apache provided general functions (e.g., ap_cpystrn)
9219 - Public API functions (e.g., palloc, bgets)
9220 - Private functions which we can't make static (because of
9221 cross-object usage) but should be (e.g., new_connection)
9222 For backward source compatibility a new header file named compat.h was
9223 created which provides defines for the old symbol names and can be used
9224 by third-party module authors.
9227 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
9228 problem under SVR4 is that there is no command flag to force the linker
9229 to export the global symbols of the httpd executable therewith they are
9230 available to the DSO's. Instead of problematic hacks like creating a
9231 dummy.so file (containing dummy references to all global symbols) the
9232 httpd binary is linked against, we use a clean trick stolen from Perl 5:
9233 Placing the Apache core code itself into a DSO library named libhttpd.so.
9234 This way the global symbols _HAVE_ to be exported and thus are available
9235 to any manually loaded DSO's under runtime. To reduce the impact to the
9236 user to null we go even further and create a stub httpd executable which
9237 automatically keeps track of the DSO library loading itself and thus
9238 hides the complete mechanism from the user. Although the generation of
9239 this DSO library is automatically triggered for platforms which
9240 essentially need it (mostly all SVR4-derivates) it can be also enabled
9241 manually via the Rule SHARED_CORE. This can be interesting in the future
9242 where we perhaps exploit this libhttpd.so mechanism for providing nifty
9243 features like graceful upgrades, or whatever.
9244 [Ralf S. Engelschall, Martin Kraemer]
9246 *) Build the libraries before building the rest of the tools. [Ben Hyde]
9248 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
9249 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
9250 conventions while "clean" removes only stuff created by "all" targets,
9251 "distclean" additionally removes the stuff from the configuration
9252 process. This way "make distclean" (hence the name) provides a fresh
9253 source tree as it was for distribution.
9254 [Ralf S. Engelschall]
9256 *) Allow top-level (APACI) Makefile to break on build errors
9257 the same way the src/ subtree Makefiles breaks on them by replacing the
9258 initial APACI sed-subdir-display-kludge with a more clean
9259 variable-passing-solution: variable SDP can optionally hold the subdir
9260 prefix which is consistently used for displaying the subdir movement.
9261 This way even the top-level Makefile can stop correctly on errors as the
9262 user expects. [Ralf S. Engelschall]
9264 *) Fixed ordering of argument checks for RewriteBase directive.
9265 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
9267 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
9268 indicating that a module is being compiled for dynamic loading. Also
9269 remove #define IS_MODULE from modules and add SHARED_MODULE define
9270 to the mak/dsp files. [Alexei Kosut]
9272 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
9273 since we are now logging APLOG_WARNING by default. [Roy Fielding]
9275 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
9277 *) Add documentation file and src/Configuration.tmpl entry for the
9278 experimental mod_mmap_static module. Because although it is and marked as
9279 an experimental one it is distributed and thus should be documented and
9280 prepared for configuration the same way as all others modules.
9281 [Ralf S. Engelschall]
9283 *) Add query (-q) option to apxs support tool to be able to manually query
9284 specific settings from apxs. This is needed for instance when you
9285 manually want to access Apache's header files and you need to assemble
9286 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
9287 [Ralf S. Engelschall]
9289 *) Now src/Configure uses a fallback strategy for the shared object support
9290 on platforms where no explicit information is available: If a Perl
9291 installation exists we ask it about its shared object support and if it's
9292 the dlopen-style one we shamelessly guess the compiler and linker flags
9293 for creating shared objects from Perls knowledge. Of course, the user is
9294 warning about what we are doing and informed that he should send us
9295 the guessed flags when they work. [Ralf S. Engelschall]
9297 *) Provide APACI --without-support option to be able to disable the build
9298 and installation of the support tools from the src/support/ area.
9299 Although its useful to have these installed per default we should provide
9300 a way to compile and install without them for backward-compatibility.
9301 [Ralf S. Engelschall]
9303 *) Add of the new APache eXtenSion (apxs) support tool for building and
9304 installing modules into an _already installed_ Apache package through the
9305 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
9306 this approach actually doesn't need the Apache source tree. The
9307 (APACI-installed) server package is enough, because this now includes the
9308 Apache C header files (PREFIX/include) and the new APXS tool
9309 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
9310 module authors to build their Apache modules _OUTSIDE_ the Apache source
9311 tree while avoiding them to fiddle around with the totally platform
9312 dependend way of compiling DSO files. The tool supports all ranges of
9313 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
9314 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
9315 on-the-fly generate a minimalistic Makefile and sample module for the
9316 first step to provide both a quick success event and to demonstrate the
9317 APXS mechanism to module authors. [Ralf S. Engelschall]
9319 *) Fix core dumps in use of CONNECT in proxy.
9320 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
9322 *) Modify the log directives in httpd.conf-dist files to use CustomLog
9323 so that users have examples of how CustomLog can be used.
9326 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
9327 the Apache distribution tree. Until Apache 1.3 there was no real
9328 out-of-the-box batch-capable build and installation procedure for the
9329 complete Apache package. This is now provided by a top-level "configure"
9330 script and a corresponding top-level "Makefile.tmpl" file. The goal is
9331 to provide a GNU Autoconf-style frontend which is capable to both drive
9332 the old src/Configure stuff in batch and additionally installs the
9333 package with a GNU-conforming directory layout. Any options from the old
9334 configuration scheme are available plus a lot of new options for flexibly
9335 customizing Apache. [Ralf S. Engelschall]
9337 *) The floating point ap_snprintf code wasn't threadsafe.
9338 Had to remove the HAVE_CVT macro in order to do threadsafe
9339 calling of the ?cvt() floating point routines. [Dean Gaudet]
9341 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
9343 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
9344 [Jim Jagielski] PR#1901
9346 *) BUG: Configure was using TCC and CC inconsistently. Make sure
9347 Configure knows which CC we are using. [Jim Jagielski]
9349 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
9350 was defined in a parent directory. [Lars Eilebrecht]
9352 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
9353 a generic printf-style routine that can call arbitrary output
9354 routines. Use this to replace http_bprintf.c. Add new routines
9355 psprintf(), pvsprintf() which allocate the exact amount of memory
9356 required for a string from a pool. Use psprintf() to clean up
9357 various bits of code which used ap_snprintf()/pstrdup().
9360 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
9361 ap_snprintf() has different semantics and formatting codes than
9362 snprintf(). [Dean Gaudet]
9364 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
9365 is necessary on at least Solaris where the /etc/rc?.d scripts
9366 are run with these signals ignored, and "SIG_IGN" settings are
9367 maintained across exec().
9368 [Rein Tollevik <reint sys.sol.no>] PR#2009
9370 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
9371 used instead of lstat() and thus this flag didn't work as expected.

9374 *) Fix the proxy pass-through feature of mod_rewrite for the case of
9375 existing QUERY_STRING now that mod_proxy was recently changed because of
9376 the new URL parsing stuff. [Ralf S. Engelschall]
9378 *) A few changes to scoreboard definitions which helps gcc generate
9379 better code. [Dean Gaudet]
9381 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
9382 be a signed bitfield. So mark a few bitfields as signed to
9383 ensure correct code. [Dean Gaudet]
9385 *) The default for HostnameLookups was changed to Off, but there
9386 was a problem and it wasn't taking effect. [Dean Gaudet]
9388 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
9391 *) After a SIGHUP the listening sockets in the parent weren't
9392 properly marked for closure on fork().
9393 [Jürgen Keil <jk tools.de>] PR#2000
9395 *) Allow %2F in two situations: 1) it is in the query part of the URI,
9396 therefore not exposed to %2F -> '/' translations and 2) the request
9397 is a proxy request, so we're not dealing with a local resource anyway.
9398 Without this, the proxy would fail to work for any URL's with
9399 %2f in them (occurs quite often in
9400 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
9402 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
9404 *) Make the shared object compilation command more portable by avoiding
9405 the direct combination of `-c' & `-o' which is not honored by some
9406 compilers like UnixWare's cc. [Ralf S. Engelschall]
9408 *) WIN32: the proxy was creating filenames missing the last four
9409 characters. While this normally doesn't stop anything from
9410 working, it can result in extra collisions.
9411 [Tim Costello <tjcostel socs.uts.edu.au>] PR#1890
9413 *) Now mod_proxy uses the response string (in addition to the response status
9414 code) from the already used FTP SIZE command to setup the Content-Length
9415 header if available. [Ralf S. Engelschall] PR#1183
9417 *) Reanimated the (still undocumented) proxy receive buffer size directive:
9418 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
9419 name was really too generic, added documentation for this directive to
9420 the mod_proxy.html and corrected the hyperlink to it in the
9421 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
9423 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
9424 faster [Martin Kraemer]
9426 *) Make Configure die when you give it an unknown command switch.
9429 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
9430 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
9431 and per default compiled support programs have manual pages - just to
9432 document our stuff a little bit more and to be able to do really
9433 Unix-like installations ;-) [Ralf S. Engelschall]
9435 *) Major cleanups to the Configure script to make it and its generated
9436 Makefiles again readable and maintainable: add SRCDIR option, removed
9437 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
9438 generated sections, consequently added Makefile headers with inheritance
9439 information, added subdir movement messages for easier following where
9440 the build process currently stays (more verbose then standard Make, less
9441 verbose than GNU make), same style to comments in the Configure script,
9442 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
9444 *) Add the new ApacheBench program "ab" to src/support/: This is derived
9445 from the ZeusBench benchmarking program and can be used to determine the
9446 response performance of an Apache installation. This version is
9447 officially licensed with Zeus Technology, Ltd. See the license agreement
9448 statements in <199803171224.NAA24547 en1.engelschall.com> in apache-core.
9449 [Ralf S. Engelschall]
9451 *) API: Various core functions that are definately not part of the API
9452 have been made static, and a few have been marked API_EXPORT. Still
9453 more have been marked CORE_EXPORT and are not intended for general
9454 use by modules. [Doug MacEachern, Dean Gaudet]
9456 *) mod_proxy was not clearing the Proxy-Connection header from
9457 requests; now it does. This did not violate any spec, however
9458 causes poor interactions when you are talking to remote proxies.
9459 [Marc Slemko] PR#1741
9461 *) Various cleanups to the command line interface and manual pages.
9462 [Ralf S. Engelschall]
9464 *) cfg_getline() was not properly handling lines that did not end
9465 with a line termination character. [Marc Slemko] PR#1869, 1909
9467 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
9469 *) Clean up some undocumented behavior of mod_setenvif related to
9470 "merging" two SetEnvIf directives when they match the same header
9471 and regex. Document that mod_setenvif will perform comparisons in
9472 the order they appear in the config file. Optimize mod_setenvif by
9473 doing more work at config time rather than at runtime.
9476 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
9477 to allow for modules to overrule them and to reduce redefinition
9478 warnings [Jim Jagielski]
9480 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
9483 *) Making the hard-coded cross-module function call mime_find_ct() (from
9484 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
9485 checking is really called even for proxy requests except for URLs with
9486 HTTP schemes (because there we can optimize by not running the type
9487 checking hooks due to the fact that the proxy gets the MIME Content-type
9488 from the remote host later). This change cleans up mod_mime by removing
9489 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
9490 especially unbundles mod_proxy and mod_mime. This way they both now can
9491 be compiled as shared objects and are no longer tied together.
9492 [Ralf S. Engelschall]
9494 *) util.c cleanup and speedup. [Dean Gaudet]
9496 *) API: Clarification, pstrndup() will always copy n bytes of the source
9497 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
9499 *) Mark module command_rec and handler_rec structures const so that they
9500 end up in the read-only data section (and are friendlier to systems
9501 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
9503 *) Add check to the "Port" directive to make sure the specified
9504 port is in the appropriate range. [Ben Hyde]
9506 *) Performance improvements to invoke_handler().
9507 [Dmitry Khrustalev <dima bog.msu.su>]
9509 *) Added support for building shared objects even for library-style modules
9510 (which are built from more than one object file). This now provides the
9511 ability to build mod_proxy as a shared object module. Additionally
9512 modules like mod_example are now also supported for shared object
9513 building because the generated Makefiles now no longer assume there is at
9514 least one statically linked module. [Ralf S. Engelschall]
9516 *) API: Clarify usage of content_type, handler, content_encoding,
9517 content_language and content_languages fields in request_rec. They
9518 must always be lowercased; and the strings pointed to shouldn't
9519 be modified (you must copy them to modify them). Fix a few bugs
9520 related to this. [Dean Gaudet]
9522 *) API: Clarification: except for RAW_ARGS, all command handlers can
9523 treat the char * parameters as permanent, and modifiable. There
9524 is no need to pstrdup() them. Clean up some needless pstrdup().
9527 *) Now mod_so keeps track of which module shared objects with which names
9528 are loaded and thus avoids multiple loading and unloading and irritating
9529 error_log messages. [Ralf S. Engelschall]
9531 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
9532 environment variable in the apache core. But that tweaking interferes
9533 with mod_setenv. So don't tweak if the user has specified an explicit
9534 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888
9536 *) rputs() did not calculate r->sent_bodyct properly.
9537 [Siegmund Stirnweiss <siegst kat.ina.de>] PR#1900
9539 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
9540 name, or left unset if this value is unavailable. Apache was setting
9541 it to the IP address when unavailable.
9542 [Tony Finch <fanf demon.net>] PR#1925
9544 *) Various improvements to the configuration and build support for compiling
9545 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
9546 OSF1 support with GCC and vendor compilers was added. This way shared
9547 object support is now provided out-of-the-box for FreeBSD, Linux,
9548 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
9549 [Ralf S. Engelschall]
9551 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
9552 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
9553 and USE_OS2_SCOREBOARD. [Dean Gaudet]
9555 *) Fix one more special locking problem for RewriteMap programs in
9556 mod_rewrite: According to the documentation of flock(), "Locks are on
9557 files, not file descriptors. That is, file descriptors duplicated
9558 through dup(2) or fork(2) do not result in multiple instances of a lock,
9559 but rather multiple references to a single lock. If a process holding a
9560 lock on a file forks and the child explicitly unlocks the file, the
9561 parent will lose its lock.". To overcome this we have to make sure the
9562 RewriteLock file is opened _AFTER_ the childs were spawned which is now
9563 the case by opening it in the child_init instead of the module_init API
9564 hook. [Ralf S. Engelschall] PR#1029
9566 *) Change to Location and LocationMatch semantics. LocationMatch no
9567 longer lets a single slash match multiple adjacent slashes in the
9568 URL. This change is for consistency with RewriteRule and
9569 AliasMatch. Multiple slashes have meaning in URLs that they do
9570 not have in (some) filesystems. Location on the other hand can
9571 be considered a shorthand for a more complicated regex, and it
9572 does match multiple slashes with a single slash -- which is
9573 also consistent with the Alias directive.
9574 [Dean Gaudet] related PR#1440
9576 *) Fix bug with mod_mime_magic causing certain files, including files
9577 of length 0, to result in no response from the server.
9580 *) The Configure script now generates src/include/ap_config.h which
9581 contains the set of defines used when Apache is compiled on a platform.
9582 This file can then be included by external modules before including
9583 any Apache header files in case they are being built separately from
9584 Apache. Along with this change, a couple of minor changes were
9585 made to make Apache's #defines coexist peacefully with any autoconf
9586 defines an external module might have. [Rasmus Lerdorf]
9588 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9589 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9590 chance by the API to initialize its per-server configuration and thus
9591 receives the wrong one from the main server. This is now avoided by
9592 remembering the server together with the config structure while
9593 configuring and later assuming there is no config when we see a
9594 difference between the remembered server and the one calling us.
9595 [Ralf S. Engelschall] PR#1790
9597 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9598 is automatically disabled under configure time when the dbm_xxx functions
9599 are not available. Second, two heavy source code errors in the DBM
9600 support code were fixed. This makes DBM RewriteMap's usable again after
9601 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9603 *) Now all configuration files support Unix-style line-continuation via
9604 the trailing backslash ("\") character. This enables us to write down
9605 complex or just very long directives in a more readable way. The
9606 backslash character has to be really the last character before the
9607 newline and it has not been prefixed by another (escaping) backslash.

9613 *) To deal with modules being compiled and [dynamically] linked
9614 at a different time from the core, the SERVER_VERSION and
9615 SERVER_BUILT symbols have been abstracted through the new
9616 API routines apapi_get_server_version() and apapi_get_server_built().
9619 *) WIN32: Preserve trailing slash in canonical path (and hence
9620 in PATH_INFO). [Paul Sutton, Ben Laurie]
9622 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
9623 depending on the rev of Solaris and what mixture of modules
9624 are in use. So it has been disabled, and Solaris is back to
9625 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9626 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9627 up static content only servers. Or it may fail unpredictably.

9630 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9633 *) API: Rewrite of absoluteURI handling, and in particular how
9634 absoluteURIs match vhosts. Unless a request is a proxy request, a
9635 "http://host" url is treated as if a similar "Host:" header had been
9636 supplied. This change was made to support future HTTP/1.x protocols
9637 which may require clients to send absoluteURIs for all requests.
9639 In order to achieve this change subtle changes were made to the API. In a
9640 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9641 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9642 by the core, modules must set it during the post_read_request or
9643 translate_names phase.
9645 Plus changes to the virtualhost test suite for absoluteURI testing.
9647 This fixes several bugs with the proxy proxying requests to vhosts
9648 managed by the same httpd.
9651 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
9652 code from mod_rewrite. The vhost matching is now performed by a
9653 globally available function matches_request_vhost(). [Dean Gaudet]

9669 *) API: A new source module main/util_uri.c; It contains a routine
9670 parse_uri_components() and friends which breaks a URI into its component
9671 parts. These parts are stored in a uri_components structure called
9672 parsed_uri within each request_rec, and are available to all modules.
9673 Additionally, an unparse routine is supplied which re-assembles the URI
9674 components back to an URI, optionally hiding the username:password@ part
9675 from ftp proxy requests, and other useful routines. Within the structure,
9676 you find on a ready-for-use basis:
9677 scheme; /* scheme ("http"/"ftp"/...) */
9678 hostinfo; /* combined [user[:password]@]host[:port] */
9679 user; /* user name, as in http://user:passwd@host:port/ */
9680 password; /* password, as in http://user:passwd@host:port/ */
9681 hostname; /* hostname from URI (or from Host: header) */
9682 port_str; /* port string (integer representation is in "port") */
9683 path; /* the request path (or "/" if only scheme://host was given) */
9684 query; /* Everything after a '?' in the path, if present */
9685 fragment; /* Trailing "#fragment" string, if present */
9686 This is meant to serve as the platform for *BIG* savings in
9687 code complexity for the proxy module (and maybe the vhost logic).
9690 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
9691 ${map:key}) available for all location where a string is created in
9692 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

9694 possible expansions are consequently usable at all string creation
9695 locations. [Ralf S. Engelschall]

9698 and not 1) and the per-virtual-server merging of directives. Now all
9699 directives except `RewriteEngine' and `RewriteOption' are either
9700 completely overridden (default) or completely inherited (when
9701 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

9710 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
9711 (like SunOS and FreeBSD) which don't accept the locking of pipes

9732 type but with a special post-processing for the looked-up value: It
9733 parses it into alternatives according to `|' chars and then only one
9734 particular alternative is chosen randomly (this is an essential
9735 functionality needed for balancing between backend-servers when using
9736 Apache as a Reverse Proxy. The looked up value here is a list of
9737 servers). Second, `int' with the built-in maps named `tolower' and
9738 `toupper' which can be used to map URL parts to a fixed case (this is an
9739 essential feature to fix the case of server names when doing mass

9744 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
9745 This directive lets Apache adjust the URL in Location-headers on HTTP
9746 redirect responses sent by the remote server. This way the virtually
9747 mapped area is no longer left on redirects and thus by-passed which is
9748 especially essential when running Apache as a reverse proxy.

9751 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
9752 hidden. [Alvaro Martinez Echevarria]
9754 *) Apache will, when started with the -X (single process) debugging flag,
9755 honor the SIGINT or SIGQUIT signals again now. This capability got lost
9756 a while ago during OS/2 signal handling changes.

9766 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
9767 In particular the handlers could trigger themselves into an infinite
9768 loop if RLimitMem was used with a small amount of memory -- too small
9769 for the signal stack frame to be set up. [Dean Gaudet]

9783 *) mod_info would occasionally produce an unpaired <tt> in its
9784 output. Fixed. [Martin Kraemer]
9786 *) By default AIX binds a process (and it's children) to a single
9787 processor. httpd children now unbind themselves from that cpu
9788 and re-bind to one selected at random via bindprocessor()
9791 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
9792 effect. Work around it by using RLIMIT_AS for the RLimitMEM
9793 directive. [Enrik Berkhan <enrik inka.de>] PR#1816
9795 *) mod_mime_magic error message should indicate the filename when
9796 reads fail. ["M.D.Parker" <mdpc netcom.com>] PR#1827
9798 *) Previously Apache would permit </Files> to end <FilesMatch> (and
9799 similary for Location and Directory), now this is diagnosed as an

9801 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).

9804 *) <Files> is not permitted within <Location> (because of the
9805 semantic ordering). [Dean Gaudet] PR#379
9807 *) <Files> with wildcards was broken by the change in wildcard
9808 semantics (* does not match /). To fix this, <Files> now
9809 apply only to the basename of the request filename. This

9821 a generally bad scene. Now the child exits immediately,

9846 *) Sort out problems with canonical filename handling happening too late.
9847 [Dean Gaudet, Ben Laurie]
9849 Changes with Apache 1.3b4
9851 *) The module structure was modified to include a *dynamic_load_handle
9852 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
9853 has been bumped accordingly. [Paul Sutton]
9855 *) All BrowserMatch directives mentioned in
9856 htdocs/manual/known_client_problems.html are in the default
9857 configuration files. [Lars Eilebrecht]
9859 *) MiNT port update. [Jan Paul Schmidt]
9861 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
9862 equivalent, similarly for x-compress and compress. Apache
9863 now ignores a leading x- when comparing encodings. It also
9864 preserves the encoding the client requests (for example if
9865 it requests x-gzip, then Apache will respond with x-gzip
9866 in the Content-Encoding header).
9867 [Ronald Tschalaer <Ronald.Tschalaer psi.ch>] PR#1772
9869 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
9871 *) Added mod_so module to support dynamic loading of modules on Unix
9872 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
9873 instead of AddModule in Configuration to build shared modules
9874 [Sameer Parekh, Paul Sutton]
9876 *) Minor cleanups to r->finfo handling in some modules.
9879 *) Abstract read()/write() to ap_read()/ap_write().
9880 Makes it easier to add other types of IO code such as SFIO.
9883 *) API: Generalize default_port manipulations to make support of
9884 different protocols easier. [Ben Laurie, Randy Terbush]
9886 *) There are many cases where users do not want Apache to form
9887 self-referential urls using the "canonical" ServerName and Port.
9888 The new UseCanonicalName directive (default on), if set to off
9889 will cause Apache to use the client-supplied hostname and port.
9890 API: Part of this change required a change to the construct_url()
9891 prototype; and the addition of get_server_name() and
9893 [Michael Douglass <mikedoug texas.net>, Dean Gaudet]
9894 PR#315, 459, 485, 1433
9896 *) Yet another rearrangement of the source tree.. now all the common
9897 header files are in the src/include directory. The -Imain -Iap
9898 references in Makefiles have been changed to the simpler -Iinclude
9899 instead. In addition to simplifying the build a little bit, this
9900 also makes it clear when a module is referencing something in a
9901 other than kosher manner (e.g., the proxy including mod_mime.h).
9902 Module-private header files (the proxy, mod_mime, the regex library,
9903 and mod_rewrite) have not been moved to src/include; nor have
9904 the OS-abstraction files. [Ken Coar]
9906 *) Fix a bug where r->hostname didn't have the :port stripped
9907 from it. [Dean Gaudet]
9909 *) Tweaked the headers_out table size, and the subprocess_env
9910 table size guess in rename_original_environment(). Added
9911 MAKE_TABLE_PROFILE which can help discover make_table()
9912 calls that use too small an initial guess, see alloc.c.
9915 *) Options and AllowOverride weren't properly merging in the main
9916 server setting inside vhosts (only an issue when you have no
9917 <Directory> or other section containing an Options that affects
9918 a request). Options +foo or -foo in the main_server wouldn't
9919 affect the main_server's lookup defaults. [Dean Gaudet]
9921 *) Variable 'cwd' was being used pointlessly before being set.
9924 *) r->allowed handling cleaned up in the standard modules.
9927 *) Some case-sensitivity issues cleaned up to be consistent with
9928 RFC2068. [Dean Gaudet]
9930 *) SIGURG doesn't exist everywhere.
9931 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
9933 *) mod_unique_id was erroneously generating a second unique id when
9934 an internal redirect occured. Such redirects occur, for example,
9935 when processing a DirectoryIndex match. [Dean Gaudet]
9937 *) API: table_add, table_merge, and table_set include implicit pstrdup()
9938 of the key and value. But in many cases this is not required
9939 because the key/value is a constant, or the value has been built
9940 by pstrcat() or other similar means. New routines table_addn,
9941 table_mergen, and table_setn have been added to the API, these
9942 routines do not pstrdup() their arguments. The core code and
9943 standard modules were changed to take advantage of these routines.
9944 The resulting server is up to 20% faster in some situations.
9946 Note that it is easy to get code subtly wrong if you pass a key/value
9947 which is in a pool other than the pool of the table. The only
9948 safe thing to do is to pass key/values which are in the pool of
9949 the table, or in one of the ancestors of the pool of the table.
9950 i.e. if the table is part of a subrequest, a value from the main
9951 request's pool is OK since the subrequest pool is a sub_pool of the
9952 main request's pool (and therefore has a lifespan at most as long as
9953 the main pool). There is debugging code which can detect improper
9954 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
9955 [Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet]
9957 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
9958 which don't exist on disk more gracefully; handles vhosts properly.
9959 Update documentation to reflect the code -- if there's no
9960 MimeMagicFile directive then the module is not enabled.
9963 *) PORT: Some older *nix dialects cannot automatically start scripts
9964 which begin with a #! interpreter line (the shell starts the scripts
9965 appropriately on these platforms). Apache now supports starting of
9966 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
9967 [Martin Kraemer, with code from Peter Wemm <peter zeus.dialix.oz.au>
9970 *) API: "typedef array_header table" removed from alloc.h, folks should
9971 have been writing to use table as if it were an opaque type, but even
9972 some standard modules got this wrong. By changing the definition
9973 to "typedef struct table table" module authors will receive compile
9974 time warnings that they're doing the wrong thing. This change
9975 facilitates future changes with more sophisticated table
9976 structures. Specifically, module authors should be using table_elts()
9977 to get access to an array_header * for the table. [Dean Gaudet]
9979 *) API: Renamed new_connection() to avoid namespace collision with LDAP
9980 library routines. [Ken Coar, Rasmus Lerdorf]
9982 *) WIN32: mod_speling is now available on the Win32 platform.
9985 *) For clarity the following compile time definition was changed:
9987 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
9989 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
9990 and not be a general notice that the OS has mmap(). Now the
9991 HAVE_MMAP/SHMGET #defines strictly are informational that the
9992 OS has that method of shared memory; the type to use for
9993 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
9994 and USE_SHMGET_SCOREBOARD). This allows outside modules to
9995 determine if shared memory is available and allows Apache
9996 to determine the best method to use for the scoreboard.
9999 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
10000 as do various earlier versions. It should be safe on all versions.
10001 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
10002 the slack code. A few other cleanups for Unixware.

10005 *) PORT: A/UX can handle single-listen accepts without mutex
10006 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
10008 *) When die() happens we need to eat any request body if one exists.
10009 Otherwise we can't continue with a keepalive session. This shows up
10010 as a POST problem with MSIE 4.0, typically against pages which are
10011 authenticated. [Roy Fielding] PR#1399
10013 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
10014 header will be passed to CGIs. This is generally a security hole, so
10015 it's not a default. [Marc Slemko] PR#549

10022 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
10024 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
10025 The choice of flock vs. fcntl was made based on timings which showed that
10026 even on non-NFS, non-exported filesystems fcntl() was an order of
10027 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
10028 that single socket users will see no difference. [Dean Gaudet] PR#467
10030 *) "File does not exist" error message was erroneously including the
10031 errno. [Marc Slemko]
10033 *) Improve the warning message generated when a client drops the
10034 connection (hits stop button, etc.) during a send. [Roy Fielding]
10036 *) Defining GPROF will disable profiling in the parent and enable it
10037 in the children. If you're profiling under Linux this is pretty much
10038 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
10040 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
10043 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some

10047 *) Some linkers complain when .o files contain no functions.

10050 *) Some const declarations in mod_imap.c that were added for debugging
10051 purposes caused some compilers heartburn without adding any
10052 significant value, so they've been removed. [Ken Coar]
10054 *) The src/main/*.h header files have had #ifndef wrappers added to
10055 insulate them against duplicate calls if they get included through
10056 multiple paths (e.g., in .c files as well as other .h files).
10059 *) The libap routines now have a header file for their prototypes,
10060 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
10062 *) mod_autoindex with a plaintext header file would emit the <PRE>
10063 start-tag before the HTML preamble, rather than after the preamble
10064 but before the header file contents. [John Van Essen <jve gamers.org>]
10067 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
10068 only an issue on systems without a MAXDNAME define or where
10069 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
10071 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
10072 is used to read various types of files such as htaccess and
10073 htpasswd files. [Marc Slemko]
10075 *) SECURITY: Ensure that the buffer returned by ht_time is always
10076 properly null terminated. [Marc Slemko]
10078 *) The "Connection" header could be sent back with multiple "close"
10079 tokens. Not an error, but a waste.
10080 [<Ronald.Tschalaer psi.ch>] PR#1683
10082 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
10083 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
10085 *) "basic" auth needs a case-insensitive comparison.
10086 [<Ronald.Tschalaer psi.ch>] PR#1666
10088 *) For maximum portability, the environment passed to CGIs should
10089 only contain variables whose names match the regex
10090 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
10091 underscores over any character outside the regex. This
10092 affects HTTP_* variables, in a way that should be backward
10093 compatible for all the standard headers; and affects variables
10094 set with SetEnv/BrowserMatch and similar directives.
10097 *) mod_speling returned incorrect HREF's when an ambigous match
10098 was found. Noticed by <robinton amtrash.comlink.de> (Soeren Ziehe)

10105 *) PORT: Fix problem killing children when terminating. Allow ^C
10106 to shut down the server. [Brian Havard]
10108 *) pstrdup() is implicit in calls to table_* functions, so there's
10109 no need to do it before calling. Clean up a few cases.

10133 *) SECURITY: Numerous changes to mod_imap in a general cleanup
10134 including fixing a possible buffer overflow. [Dean Gaudet]
10136 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
10137 (connections are not dropped). Code can handle graceful restarts
10138 (but there is as yet no way to signal this to Apache). Various
10139 other cleanups. [Paul Sutton]
10141 *) The aplog_error changes specific to 1.3 introduced a buffer
10142 overrun in the (now legacy) log_printf function. Fixed.
10145 *) mod_digest didn't properly deal with proxy authentication. It
10146 also lacked a case-insensitive comparision of the "Digest"

10158 ap_cpystrn() for performance and functionality reasons.

10178 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
10180 *) send_fd_length() did not calculate total_bytes_sent properly.
10181 [Ben Reser <breser regnow.com>] PR#1366
10183 *) The bputc() macro was not properly integrated with the chunking
10184 code; in many cases modules using bputc() could cause completely
10185 bogus chunked output. (Typically this will show up as problems
10186 with Internet Explorer 4.0 reading a page, but other browsers
10187 having no problem.) [Dean Gaudet]
10189 *) Create LARGE_WRITE_THRESHOLD define which determines how many
10190 bytes have to be supplied to bwrite() before it will consider
10191 doing a writev() to assemble multiple buffers in one system
10192 call. This is critical for modules such as mod_include,
10193 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
10194 strings in some cases. The result would be extra effort
10195 setting up writev(), and in many cases extra effort building
10196 chunks. The default is 31, it can be overriden at compile
10197 time. [Dean Gaudet]

10264 *) proxy_ftp: the directory listings generated by the proxy ftp module
10265 now have a title in which the path components are clickable and allow
10266 quick navigation to the clicked-on directory on the currently listed
10267 ftp server. This also fixes a bug where the ".." directory links would
10268 sometimes refer to the wrong directory. [Martin Kraemer]
10270 *) WIN32: Allocate the correct amount of memory for the scoreboard.
10273 *) WIN32: Only lowercase the part of the path that is real. [Ben Laurie]
10276 *) Fix problems with timeouts in inetd mode and -X mode. [Dean Gaudet]
10278 *) Fix the spurious "(0)unknown error: mmap_handler: mmap failed"
10279 error messages. [Ben Hyde]
10281 Changes with Apache 1.3b3
10283 *) WIN32: Work around brain-damaged spawn calls that can't deal
10284 with spaces and slashes. [Ben Laurie]
10286 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
10287 The problem was that certain undocumented environment variables
10288 needed for sockets to work under Win32 were not being passed.
10289 [Frank Faubert <frank sane.com>]
10291 *) Add a "-V" command line flag to the httpd binary. This
10292 flag shows some of the defines that Apache was compiled with.
10293 It is useful for debugging purposes. [Martin Kraemer]
10295 *) Start separating the ap_*() routines into their own library, so they
10296 can be used by items in src/support among other things.
10297 [Ken Coar] PR#512, 905, 1252, 1308
10299 *) Give a more informative error when no AuthType is set.
10302 *) Remove strtoul() use from mod_proxy because it isn't available
10303 on all platforms. [Marc Slemko] PR#1214
10305 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
10306 This turns out to be a bug in Winsock - select() doesn't always
10307 return the correct status. [Ben Laurie]
10309 *) Directives owned by http_core can now use the new check_cmd_context()
10310 routine to ensure that they're not being used within a container
10311 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
10313 *) PORT: Recent changes made it necessary to add explicit prototype
10314 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
10316 *) It was necessary to distinguish between resources which are
10317 allocated in the parent, for cleanup in the parent, and resources
10318 which are allocated in each child, for cleanup in each child.
10319 A new pool was created which is passed to the module child_init
10320 and child_exit functions; modules are free to register per-child
10321 cleanups there. This fixes a bug with reliable piped logs.
10324 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
10325 unless it was also doing FancyIndexes, but it displayed the
10326 HeaderName file at the top under all circumstances. It now shows
10327 the ReadmeName file for simple indices, too, as it should.
10330 *) http_core was mmap()ing even in cases where it wasn't going to
10331 read the file. [Ben Hyde <bhyde gensym.com>]
10333 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
10334 Now the rewriting engine (the heart of mod_rewrite) is organized more
10335 straight-forward, first time well documented and reduced to the really
10336 essential parts. All redundant cases were stripped off and processing now
10337 is the same for both per-server and per-directory context with only a
10338 minimum difference (the prefix stripping in per-dir context). As a
10339 side-effect some subtle restrictions and two recently discovered problems
10340 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
10341 context and restrictions on the substitution URL on redirects.
10342 Additionally some minor source cleanups were done.

10345 *) Lars Eilebrecht wrote a whole new set of Apache Vhost Internals
10346 documentation, examples, explanations and caveats. They live in a new

10349 *) If ap_slack fails to allocate above the low slack line it's a good
10350 indication that further problems will occur; it's a better indication
10351 than many external libraries give us when we actually run out of
10352 descriptors. So report it to the user once per restart.

10484 server settings in <VirtualHost> blocks, flagging unhandled multiple
10485 arguments to <Directory>, <Files> etc.)

10489 variable to provide this one to suexec'd CGIs, too.
10490 [M.D.Parker <mdpc netcom.com>] PR#1284
10492 *) New support tool: src/support/split-logfile, a sample Perl script which
10493 splits up a combined access log into separate files based on the
10494 name of the virtual host (listed first in the log records by "%v").
10497 Changes with Apache 1.3b2 (there is no 1.3b1)
10499 *) TestCompile was not passing $LIBS [Dean Gaudet]
10501 *) Makefile.tmpl was not using $CFLAGS in the link phase.
10504 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
10505 rudimentary memory debugger which can be used on live servers with
10506 low impact -- it sets all allocated and freed memory bytes to 0xa5.
10507 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
10508 and free() for each object. This is far more expensive and should
10509 only be used for testing with tools such as Electric Fence and
10510 Purify. See main/alloc.c for more details. [Dean Gaudet]
10512 *) Configure uses a sh trap and didn't set its exitcode properly.
10513 [Dean Gaudet] PR#1159
10515 *) Yet another vhost revamp. Add the NameVirtualHost directive which
10516 explicitly lists the ip:port pairs that are to be used for name-vhosts.
10517 From a given ip:port, regardless what the Host: header is, you can
10518 only reach the vhosts defined on that ip:port. The precedence of
10519 vhosts was reversed to match other precedences in the config --
10520 the earlier vhosts override the later vhosts. All vhost matching was
10521 moved into http_vhost.[ch]. [Dean Gaudet]
10523 *) ap_inline can be used to force inlining. GNUC __attribute__() can
10524 be used for whatever reason is appropriate (i.e. format() warnings
10525 for printf style functions). Both are enabled only with
10526 gcc >= 2.7.x (so that we have fewer support issues with older
10527 versions). [Dean Gaudet]
10529 *) Fix support for Proxy Authentication (we were testing the response
10530 status too early). [Marc Slemko]
10532 *) CoreDumpDirectory directive directs where the core file is
10533 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
10534 received. [Marc Slemko, Dean Gaudet]
10536 *) PORT: Support for Atari MINT.
10537 [Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
10539 *) When booting, apache will now detach itself from stdin, stdout,
10540 and stderr. stderr will not be detached until after the config
10541 files have been read so you will be able to see initial error
10542 messages. After that all errors are logged in the error_log.
10543 This makes it more convenient to start apache via rsh, ssh,
10544 or crontabs. [Dean Gaudet] PR#523
10546 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10547 Also removed the auto-generated link to www.apache.org that was the
10548 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10550 *) send_fb would not detect aborted connections in some situations.
10553 *) mod_include would use uninitialized data when parsing certain
10554 expressions involving && and ||. [Brian Slesinsky] PR#1139
10556 *) mod_imap should only handle GET methods. [Jay Bloodworth]
10558 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10560 *) mod_autoindex improperly counted &escapes; as more than one
10561 character in the description. It also improperly truncated
10562 descriptions that were exactly the maximum length.
10565 *) RedirectMatch was not properly escaping the result (PR#1155). Also
10566 "RedirectMatch /advertiser/(.*) $1" is now permitted.
10569 *) mod_include now uses symbolic names to check for request success
10570 and return HTTP errors, and correctly handles all types of
10571 redirections (previously it only did temporary redirect correctly).
10572 [Ken Coar, Roy Fielding]
10574 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10575 r->filename. Since those two are meant to be in sync with each other
10576 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
10578 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
10579 ["Kaufman, Steven E" <Steven.Kaufman unisys.com>]
10581 *) Inetd mode (which is buggy) uses timeouts without having setup the
10582 jmpbuffer. [Dean Gaudet] PR#1064
10584 *) Work around problem under Linux where a child will start looping
10585 reporting a select error over and over.
10586 [Rick Franchuk <rickf transpect.net>] PR#1107, 987, 588
10588 *) Fixed error in proxy_util.c when looping through multiple host IP
10589 addresses. [Lars Eilebrecht] PR#974
10591 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10592 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10593 bytes before writing, but it will never split a log entry across a
10594 buffer boundary. [Dean Gaudet]
10596 *) API: the short_score record has been split into two pieces, one which
10597 the parent writes on, and one which the child writes on. As part of
10598 this change the get_scoreboard_info() function was removed, and
10599 scoreboard_image was exported. This change fixes a race condition
10600 in file based scoreboard systems, and speeds up changes involving the
10601 scoreboard in earlier 1.3 development. [Dean Gaudet]
10603 *) API: New register_other_child() API (see http_main.h) which allows
10604 modules to register children with the parent for maintenance. It
10605 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10607 *) API: New piped_log API (see http_log.h) which implements piped logs,
10608 and will use register_other_child to implement reliable piped logs
10609 when it is available. The reliable piped logs part can be disabled
10610 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10611 logs is only available on Unix. [Dean Gaudet]
10613 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10614 meets_conditions(). This allows conditional HTTP selection to be
10615 handled separately from the storing of the header fields, and provides
10616 the ability for CGIs to set their own ETags for conditional checking.
10617 [Ken Coar, Roy Fielding] PR#895
10619 *) Changes to mod_log_config to allow naming of format strings.
10620 Format nicknames are defined with "LogFormat fmt nickname", and can
10621 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
10624 *) New module, "mod_speling", which can help find files even when
10625 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
10627 *) API: New function child_terminate() triggers the child process to
10628 exit, while allowing the child finish what it needs to for the
10629 current request first.
10630 [Doug MacEachern, Alexei Kosut]
10632 *) Windows now defaults to using full status reports with mod_status.
10633 [Alexei Kosut] PR #1094
10635 *) *Really* disable all mod_rewrite operations if the engine is off.
10636 Some things (like RewriteMaps) were checked/performed even if they
10637 weren't supposed to be. [Ken Coar] PR #991
10639 *) Implement a new timer scheme which eliminates the need to call alarm() all
10640 the time. Instead a counter in the scoreboard for each child is used to
10641 show when the child has made forward progress. The parent samples this
10642 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10643 progress has been made in the timeout period. This reduces the static
10644 request best-case syscall count to 22 from 29. This scheme is only
10645 used by systems with memory-based scoreboards. [Dean Gaudet]
10647 *) The proxy now properly handles CONNECT requests which are sent
10648 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10650 *) A script called apachectl has been added to the support
10651 directory. This script allows you to do things such as
10652 "apachectl start" and "apachectl restart" from the command
10653 line. [Marc Slemko]
10655 *) Modules and core routines are now put into libraries, which
10656 simplifies the link line tremendously (among other advantages).
10659 *) Some of the MD5 names defined in Apache have been renamed to have
10660 an `ap_' prefix to avoid conflicts with routines supplied by
10661 external libraries. [Ken Coar]
10663 *) Removal of mod_auth_msql.c from the distribution. There are many
10664 other options for databases today. Rather than offer one option,
10665 offer none at this time. mod_auth_msql and other SQL database
10666 authentication modules can be found at the Apache Module Registry.
10667 http://modules.apache.org/ It would be nice to offer a generic
10668 mod_auth_sql option in the near future.
10670 *) PORT: BeOS support added [Alexei Kosut]
10672 *) Configure no longer accepts the -make option, since it creates
10673 Makefile on the fly based on Makefile.tmpl and Configuration.
10675 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
10676 of forcibly killing off all its processes and exiting without
10677 cleaning up. [Alexei Kosut]
10679 *) API: A new field in the request_rec, r->mtime, has been added to
10680 avoid gratuitous parsing of date strings. It is intended to hold
10681 the last-modified date of the resource (if applicable). An
10682 update_mtime() routine has also been added to advance it if
10683 appropriate. [Roy Fielding, Ken Coar]
10685 *) SECURITY: If a htaccess file can not be read due to bad permissions,
10686 deny access to the directory with a HTTP_FORBIDDEN. The previous
10687 behavior was to ignore the htaccess file if it could not be read.
10688 This change may make some setups with unreadable htaccess files
10689 stop working. [Marc Slemko] PR#817
10691 *) Add aplog_error() providing a mechanism to define levels of
10692 verbosity to the server error logging. This addition also provides
10693 the ability to log errors using syslogd. Error logging is configurable
10694 on a per-server basis using the LogLevel directive. Conversion
10695 of log_*() in progress. [Randy Terbush]
10697 *) Further enhance aplog_error() to not log filename, line number, and
10698 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
10700 *) WIN32: Canonicalise filenames under Win32. Short filenames are
10701 converted to long ones. Backslashes are converted to forward
10702 slashes. Case is converted to lower. Parts of URLs that do not
10703 correspond to files are left completely alone. [Ben Laurie]
10705 *) PORT: 2 new OSs added to the list of ports:
10706 Encore's UMAX V: Arieh Markel <amarkel encore.com>
10707 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
10709 *) Add the server version (SERVER_VERSION macro) to the "server
10710 configured and running" entry in the error_log. Also build an
10711 object file at link-time that contains the current time
10712 (SERVER_BUILT global const char[]), and include that in the
10713 message. [Ken Coar]
10715 *) Set r->headers_out when sending responses from the proxy.
10716 This fixes things such as the logging of headers sent from
10717 the proxy. [Marc Slemko] PR#659
10719 *) support/httpd_monitor is no longer distributed because the
10720 scoreboard should not be file based if at all possible. Use
10721 mod_status to see current server snapshot.
10723 *) (set_file_slot): New function, allowing auth directives to be
10724 independent of the server root, so the server documents can be
10725 moved to a different directory or machine more easily.
10726 [David J. MacKenzie]
10728 *) If no TransferLog is given explicitly, decline
10729 to log. This supports coexistence with other logging modules,
10730 such as the custom one that UUNET uses. [David J. MacKenzie]
10732 *) Check for titles in server-parsed HTML files.
10733 Ignore leading newlines and returns in titles. The old behavior
10734 of replacing a newline after <title> with a space causes the
10735 title to be misaligned in the listing. [David J. MacKenzie]
10737 *) Change mod_cern_meta to be configurable on a per-directory basis.
10738 [David J. MacKenzie]
10740 *) Add 'Include' directive to allow inclusion of configuration
10741 files within configuration files. [Randy Terbush]
10743 *) Proxy errors on connect() are logged to the error_log (nothing
10744 new); now they include the IP address and port that failed
10745 (*that's* new). [Ken Coar, Marc Slemko] PR#352
10747 *) Various architectures now define USE_MMAP_FILES which causes
10748 the server to use mmap() for static files. There are two
10749 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
10750 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
10751 number of bytes written in one cycle from a single mmap()d object,
10752 default 32768). [Dean Gaudet]
10754 *) API: Added post_read_request API phase which is run right after reading
10755 the request from a client, or right after an internal redirect. It is
10756 useful for modules setting environment variables that depend only on
10757 the headers/contents of the request. It does not run during subrequests
10758 because subrequests inherit pretty much everything from the main
10759 request. [Dean Gaudet]
10761 *) Added mod_unique_id which is used to generate a unique identifier for
10762 each hit, available in the environment variable UNIQUE_ID.
10765 *) init_modules is now called after the error logs have been opened. This
10766 allows modules to emit information messages into the error logs.
10769 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10770 information for case where proxy module is not available. [Marc Slemko]
10772 *) PORT: Apache has need for mutexes to serialize its children around
10773 accept. In prior versions either fcntl file locking or flock file
10774 locking were used. The method is chosen by the definition of
10775 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
10776 and FLOCK for flock(). New options have been added:
10777 - SYSVSEM to use System V style semaphores
10778 - PTHREAD to use POSIX threads (appears to work on Solaris only)
10779 - USLOCK to use IRIX uslock
10780 Based on timing various techniques, the following changes were made
10782 - Linux 2.x uses flock instead of fcntl
10783 - Solaris 2.x uses pthreads
10784 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
10785 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
10786 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
10787 Martijn Koster <m.koster pobox.com>]
10789 *) PORT: The semantics of accept/select make it very desirable to use
10790 mutexes to serialize accept when multiple Listens are in use. But
10791 in the case where only a single socket is open it is sometimes
10792 redundant to serialize accept(). Not all unixes do a good job with
10793 potentially dozens of children blocked on accept() on the same
10794 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
10795 the server will avoid serialization when listening on only one socket,
10796 and use serialization when listening on multiple sockets.
10797 [Dean Gaudet] PR#467
10799 *) Configure changes: TestLib replaced by TestCompile, which has
10800 some additional capability (such as doing a sanity check of
10801 the compiler and flags selected); the version of Solaris is now
10802 available via the #define value of SOLARIS2; IRIX n32bit libs
10803 now supported and selectable by new Configuration Rule: IRIXN32;
10804 We no longer default to -O2 optimization. [Jim Jagielski]
10806 *) Updated Configure: Configuration now uses AddModule to specify
10807 module source or binary file location, relative to src directory.
10808 Modules can be dropped into modules/extra, or in their own
10809 directory, and modules can come with a Makefile or Configure can
10810 create one. Modules can add compiler or library information to
10811 generated Makefiles. [Paul Sutton]
10813 *) Source core re-organisation: distributed modules are now in
10814 modules/standard. All other source code is in main. OS-specific
10815 code is in os/{unix,emx,win32} directories. [Paul Sutton]
10817 *) mod_browser has been removed, since it's replaced by mod_setenvif.
10820 *) Fix another long-standing bug in sub_req_lookup_file where it would
10821 happily skip past access checks on subdirectories looked up with
10822 relative paths. (It's used by mod_dir, mod_negotiation,
10823 and mod_include.) [Dean Gaudet]
10825 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
10826 N is the number of <Directory> sections, and M is the number of
10827 components in the filename of an object.
10829 To achieve this optimization the following config changes were made:
10830 - Wildcards (* and ?, not the regex forms) in <Directory>s,
10831 <Files>s, and <Location>s now treat a slash as a special
10832 character. For example "/home/*/public_html" previously would
10833 match "/home/a/andrew/public_html", now it only matches things
10834 like "/home/bob/public_html". This mimics /bin/sh behaviour.
10835 - It's possible now to use [] wildcarding in <Directory>, <Files>
10837 - Regex <Directory>s are applied after all non-regex <Directory>s.
10841 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
10842 and corrupted paths. [Dean Gaudet]
10844 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
10845 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
10846 be accessed now via backreferences $1..$9 in RewriteConds test-against
10847 strings in addition to RewriteRules subst string. Second the grouped
10848 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
10849 via backreferences %1..%9 both in following RewriteCond test-against
10850 strings and RewriteRules subst string. This provides maximum flexibility
10851 through the use of backreferences.
10852 Additionally the rewriting engine was cleaned up by putting common
10853 code to the new expand_backrefs_inbuffer() function.
10854 [Ralf S. Engelschall]
10856 *) When merging the main server's <Directory> and <Location> sections into
10857 a vhost, put the main server's first and the vhost's second. Otherwise
10858 the vhost can't override the main server. [Dean Gaudet] PR#717
10860 *) The <Directory> code would merge and re-merge the same section after
10861 a match was found, possibly causing problems with some modules.
10864 *) ip-based vhosts are stored and queried using a hashing function, which
10865 has been shown to improve performance on servers with many ip-vhosts.
10866 Some other changes had to be made to accommodate this:
10867 - the * address for vhosts now behaves like _default_
10868 - the matching process now is:
10869 - match an ip-vhost directly via hash (possibly matches main
10871 - if that fails, just pretend it matched the main server
10872 - if so far only the main server has been matched, perform
10873 name-based lookups (ServerName, ServerAlias, ServerPath)
10874 *only on name-based vhosts*
10875 - if they fail, look for _default_ vhosts
10876 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
10878 *) dbmmanage overhaul:
10879 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
10880 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
10881 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
10882 - provide better seed for rand
10883 - prompt for password as per getpass(3) (turn off echo, read from
10885 - use "newstyle" crypt based on $Config{osname} ($^O)
10886 - will not add a user if already in database, use new `update' command
10888 - added `check' command to check a users' password
10889 - added `import' command to convert existing password text-files or
10890 dbm files exported with `view'
10891 - more descriptive usage, general cleanup, 'use strict' clean, etc.
10894 *) Added psocket() which is a pool form of socket(), various places within
10895 the proxy weren't properly blocking alarms while registering the cleanup
10896 for its sockets. bclose() now uses pclose() and pclosesocket(). There
10897 was a bug where the client socket was being close()d twice due a still
10898 registered cleanup. [Dean Gaudet]
10900 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
10903 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
10904 [Jason Venner <jason idiom.com>] PR#667
10906 *) Enable ``=""'' for RewriteCond directives to match against
10907 the empty string. This is the preferred way instead of ``^$''.
10908 [Ralf S. Engelschall]
10910 *) Fixed an infinite loop in mod_imap for references above the server root
10911 [Dean Gaudet] PR#748
10913 *) mod_proxy now has a ReceiveBufferSize directive, similar to
10914 SendBufferSize, so that the TCP window can be set appropriately
10915 for LFNs. [Phillip A. Prindeville]
10917 *) mod_browser has been replaced by the more general mod_setenvif
10918 (courtesy of Paul Sutton). BrowserMatch* directives are still
10919 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
10920 UnSetEnvIfZero directives. [Ken Coar]
10922 *) "HostnameLookups double" forces double-reverse DNS to succeed in
10923 order for remote_host to be set (for logging, or for the env var
10924 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
10927 *) mod_access overhaul:
10928 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
10929 and cidr syntax (i.e. 10.1.0.0/16). PR#762
10930 - Critical path was sped up by pre-computing a few things at config time.
10931 - The undocumented syntax "allow user-agents" was removed,
10932 the replacement is "allow from env=foobar" combined with mod_browser.
10933 - When used with hostnames it now forces a double-reverse lookup
10934 no matter what the directory settings are. This double-reverse
10935 doesn't affect any of the other routines that use the remote
10936 hostname. In particular it's still passed to CGIs and the log
10937 without the double-reverse check. Related PR#860.
10940 *) When a large bwrite() occurs (larger than the internal buffer size),
10941 while there is already something in the buffer, apache will combine
10942 the large write and the buffer into a single writev(). (This is
10943 in anticipation of using mmap() for reading files.)
10946 *) In obscure cases where a partial socket write occurred while chunking,
10947 Apache would omit the chunk header/footer on the next block. Cleaned
10948 up other bugs/inconsistencies in error conditions in buff.c. Fixed
10949 a bug where a long pause in DNS lookups could cause the last packet
10950 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
10952 *) API: Added child_exit function to module structure. This is called
10953 once per "heavy-weight process" just before a server child exit()'s
10954 e.g. when max_requests_per_child is reached, etc.
10955 [Doug MacEachern, Dean Gaudet]
10957 *) mod_include cleanup showed that handle_else was being used to handle
10958 endif. It didn't cause problems, but it was cleaned up too.
10961 *) mod_cern_meta would attempt to find meta files for the directory itself
10962 in some cases, but not in others. It now avoids it in all cases.
10965 *) mod_mime_magic would core dump if there was a decompression error.
10966 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
10968 *) PORT: some variants of DGUX require -lsocket -lnsl
10969 [Alexander L Jones <alex systems-options.co.uk>] PR#732
10971 *) mod_autoindex now allows sorting of FancyIndexed directory listings
10972 by the various fields (name, size, et cetera), either in ascending
10973 or descending order. Just click on the column header. [Ken Coar]
10975 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
10976 CPUs like the Alpha. Apache still stores ints in pointers, but that's
10977 the relatively safe direction. [Dean Gaudet] PR#344
10979 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
10980 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
10982 *) child_main avoids an unneeded call to select() when there is only one
10983 listening socket. [Dean Gaudet]
10985 *) In the event that the server is starved for idle servers it will
10986 spawn 1, then 2, then 4, ..., then 32 servers each second,
10987 doubling each second. It'll also give a warning in the errorlog
10988 since the most common reason for this is a poor StartServers
10989 setting. The define MAX_SPAWN_RATE can be used to raise/lower
10990 the maximum. [Dean Gaudet]
10992 *) Apache now provides an effectively unbuffered connection for
10993 CGI scripts. This means that data will be sent to the client
10994 as soon as the CGI pauses or stops output; previously, Apache would
10995 buffer the output up to a fixed buffer size before sending, which
10996 could result in the user viewing an empty page until the CGI finished
10997 or output a complete buffer. It is no longer necessary to use an
10998 "nph-" CGI to get unbuffered output. Given that most CGIs are written
10999 in a language that by default does buffering (e.g. perl) this
11000 shouldn't have a detrimental effect on performance.
11002 "nph-" CGIs, which formerly provided a direct socket to the client
11003 without any server post-processing, were not fully compatible with
11004 HTTP/1.1 or SSL support. As such they would have had to implement
11005 the transport details, such as encryption or chunking, in order
11006 to work properly in certain situations. Now, the only difference
11007 between nph and non-nph scripts is "non-parsed headers".

11010 *) If a BUFF is switched from buffered to unbuffered reading the first
11011 bread() will return whatever remained in the buffer prior to the
11012 switch. [Dean Gaudet]
11014 Changes with Apache 1.3a1
11016 *) Added another Configure helper script: TestLib. It determines
11017 if a specified library exists. [Jim Jagielski]
11019 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
11020 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
11023 *) PORT: Some architectures use size_t for various lengths in network
11024 functions such as accept(), and getsockname(). The definition
11025 NET_SIZE_T is used to control this. [Dean Gaudet]
11027 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
11028 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
11029 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
11031 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
11032 [Igor N Kovalenko <infoh mail.wplus.net>]
11034 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11035 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11036 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11037 [Dean Gaudet] related PR#875
11039 *) API: Correct child_init() slot declaration from int to void, to
11040 match the init() declaration. Update mod_example to use the new
11043 *) added transport handle slot (t_handle) to the BUFF structure
11046 *) get_client_block() returns wrong length if policy is

11055 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
11057 *) AddModuleInfo directive for mod_info which allows you to annotate
11058 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
11060 *) Added NoProxy directive to avoid using ProxyRemote for selected
11061 addresses. Added ProxyDomain directive to cause unqualified
11062 names to be qualified by redirection.
11063 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
11065 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
11066 header to the remote host in the proxy. [Sameer Parekh and
11069 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
11070 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
11071 URLs, fixed rewritelog(), fixed forced response code handling on
11072 redirects from within .htaccess files, disabled pipe locking under
11073 braindead SunOS 4.1.x, allow env variables to be set even on rules with
11074 no substitution, bugfixed situations where HostnameLookups is off, made
11075 mod_rewrite more thread-safe for NT port and fixed problem when creating
11076 an empty query string via "xxx?".
11077 This update also removes the copyright of Ralf S. Engelschall,
11078 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
11079 exclusively copyrighted by the Apache Group now. This happened because
11080 the author now has gifted mod_rewrite exclusively to the Apache Group and
11081 no longer maintains an external version.
11082 [Ralf S. Engelschall]
11084 *) API: Added child_init function to module structure. This is called
11085 once per "heavy-weight process" before any requests are handled.
11086 See http_config.h for more details. [Dean Gaudet]
11088 *) Anonymous_LogEmail was logging on each subrequest.
11089 [Dean Gaudet] PR#421, 868
11091 *) API: Added is_initial_req() which tests if the request being
11092 processed is the initial request, or a subrequest.
11095 *) Extended SSI (mod_include) now handles additional relops for
11096 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
11098 *) Configure fixed to correctly propagate user-selected options and
11099 settings (such as CC and OPTIM) to Makefiles other than
11100 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
11102 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
11103 directory indices to start with the contents of the HeaderName file
11104 if there is one. If there isn't one, the behaviour is unchanged.
11105 [Ken Coar, Roy Fielding, Andrey A. Chernov]
11107 *) WIN32: Modules can now be dynamically loaded DLLs using the
11108 LoadModule/LoadFile directives. Note that module DLLs must be
11109 compiled with the multithreaded DLL version of the runtime library.
11110 [Alexei Kosut and Ben Laurie]
11112 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
11113 This allows the admin to completely remove automatic indexing
11114 from the server, while still supporting the basic functions of
11115 trailing-slash redirects and DirectoryIndex files. Note that if
11116 you're carrying over an old Configuration file and you use directory
11117 indexing then you'll want to add:
11119 Module autoindex_module mod_autoindex.o
11121 before mod_dir in your Configuration. [Dean Gaudet]
11123 *) popendir/pclosedir created to properly protect directory scanning.
11124 [Dean Gaudet] PR#525
11126 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
11127 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
11128 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
11131 *) The AccessFileName directive can now take more than one filename.
11132 ["Lou D. Langholtz" <ldl usi.utah.edu>]
11134 *) The new mod_mime_magic can be used to "magically" determine the type
11135 of a file if the extension is unknown. Based on the unix file(1)
11136 command. [Ian Kluft <ikluft cisco.com>]
11138 *) We now determine and display the time spent processing a
11139 request if desired. [Jim Jagielski]
11141 *) mod_status: PID field of "dead" child slots no longer displays
11142 main httpd process's PID. [Jim Jagielski]
11144 *) Makefile.nt added - to build all the bits from the command line:
11145 nmake -f Makefile.nt
11146 Doesn't yet work properly. [Ben Laurie]
11148 *) Default text of 404 error is now "Not Found" rather than the
11149 potentially misleading "File Not Found". [Ken Coar]
11151 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
11152 for the net if we require people that actually need this data to
11153 enable it. [Linus Torvalds]
11155 *) directory_walk() is an expensive function, keep a little more state to
11156 avoid needless string counting. Add two new functions make_dirstr_parent
11157 and make_dirstr_prefix which replace all existing uses of make_dirstr.
11158 The new functions are a little less general than make_dirstr, but
11159 work more efficiently (less memory, less string counting).
11162 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
11163 to LDFLAGS) to avoid complications with lex rules in make files.
11164 [Dean Gaudet] PR#372
11166 *) run_method optimized to avoid needless scanning over NULLs in the
11167 module list. [Dean Gaudet]
11169 *) Revamp of (unix) scoreboard management code such that it avoids
11170 unnecessary traversals of the scoreboard on each hit. This is
11171 particularly important for high volume sites with a large
11172 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
11173 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
11174 httpd.h. [Dean Gaudet]
11176 *) In configurations using multiple Listen statements it was possible for
11177 busy sockets to starve other sockets of service. [Dean Gaudet]
11179 *) Added hook so standalone_main can be replaced at compile time
11180 (define STANDALONE_MAIN)
11183 *) Lowest-level read/write functions in buff.c will be replaced with
11184 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
11185 compile time. The default sfio discipline will behave as apache
11186 would without sfio compiled in.
11189 *) Enhance UserDir directive (mod_userdir) to accept a list of
11190 usernames for the 'disable' keyword, and add 'enable user...' to
11191 selectively *en*able userdirs if they're globally disabled.
11194 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
11195 will work with Netscape dbm files. (dbmmanage will probably not
11196 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
11198 *) Add a ListenBacklog directive to control the backlog parameter
11199 passed to listen(). Also change the default to 511 from 512.
11202 *) API: A new handler response DONE which informs apache that the
11203 request has been handled and it can finish off quickly, similar to
11204 how it handles errors. [Rob Hartill]
11206 *) Turn off chunked encoding after sending terminating chunk/footer
11207 so that we can't do it twice by accident. [Roy Fielding]
11209 *) mod_expire also issues Cache-Control: max-age headers.
11212 *) API: Added kill_only_once option for free_proc_chain so that it won't
11213 aggressively try to kill off specific children. For fastcgi.
11214 [Stanley Gambarin <gambarin OpenMarket.com>]
11216 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
11218 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
11219 When used together, these cause mod_dir to emit HEIGHT and WIDTH
11220 attributes in the FancyIndexing IMG tags. [Ken Coar]
11222 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
11224 *) PORT: Added Windows NT support

11227 Changes with Apache 1.2.6

11322 *) SECURITY: General mod_include cleanup, including fixing several
11323 possible buffer overflows and a possible infinite loop. This cleanup
11324 was done against 1.3 code and then backported to 1.2, the result
11325 is a large difference (due to indentation cleanup in 1.3 code).
11326 Users interested in seeing a smaller set of relevant differences
11327 should consider comparing against src/modules/standard/mod_include.c
11328 from the 1.3b3 release. Non-indentation changes to mod_include

11397 happily skip past access checks on subdirectories looked up with relative
11398 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
11401 *) Add lockfile name to error message printed out when
11402 USE_FLOCK_SERIALIZED_ACCEPT is defined.

11424 mod_rewrite is now directly developed by the author at the Apache Group):

11470 *) API: In HTTP/1.1, whether or not a request message contains a body
11471 is independent of the request method and based solely on the presence
11472 of a Content-Length or Transfer-Encoding. Therefore, our default
11473 handlers need to be prepared to read a body even if they don't know
11474 what to do with it; otherwise, the body would be mistaken for the
11475 next request on a persistent connection. discard_request_body()
11476 has been added to take care of that. [Roy Fielding] PR#378

11496 (headers, readmes, titles), mod_negotiation (type maps), or
11497 mod_cern_meta (meta files). [Dean Gaudet]
11499 *) SECURITY: Apache will refuse to run as "User root" unless
11500 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
11502 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
11503 if it contained a .htaccess disallowing symlinks. This is contrary
11504 to the rule that symlink permissions are tested with the symlink
11505 options of the parent directory. [Dean Gaudet] PR#353

11527 solaris libc). On all systems apache attempts to keep all permanent
11528 descriptors above 15 (called the low slack line). Solaris users
11529 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
11530 which keeps all non-FILE * descriptors above 255. On all systems
11531 this should make supporting large numbers of vhosts with many open
11532 log files more feasible. If this causes trouble please report it,
11533 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.

11667 *) The method for determining PATH_INFO has been restored to the pre-1.2b
11668 (and NCSA httpd) definition wherein it was the extra path info beyond
11669 the CGI script filename. The environment variable FILEPATH_INFO has
11670 been removed, and instead we supply the original REQUEST_URI to any
11671 script that wants to be Apache-specific and needs the real URI path.
11672 This solves a problem with existing scripts that use extra path info
11673 in the ScriptAlias directive to pass options to the CGI script.

11677 that use multiple Listen statements for listening on multiple ports.
11678 But that change is necessary to make _default_ consistent with other

11765 parsing of headers. If the terminating empty-line CRLF occurs starting
11766 at the 256th or 257th byte of output, then Navigator will think a normal
11767 image is invalid. We are guessing that this is because their initial
11768 read of a new request uses a 256 byte buffer. We check the bytes written
11769 so far and, if we are about to tickle the bug, we instead insert a
11770 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
11772 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
11773 of an external redirection. [Roy Fielding and Paul Sutton]
11775 *) Configure would create a broken Makefile if the configuration file
11776 contained a commented-out Rule. [Roy Fielding]
11778 *) Promote per_dir_config and subprocess_env from the subrequest to the
11779 main request in mod_negotiation. In particular this fixes a bug
11780 where <Files> sections wouldn't properly apply to negotiated content.
11783 *) Fix a potential deadlock in mod_cgi script_err handling.
11784 [Ralf S. Engelschall]
11786 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
11787 [Mitchell Blank Jr]
11789 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
11790 .htaccess files because the RewriteBase was not replaced correctly.
11791 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
11792 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
11794 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
11795 1.x the settings are those of pre-1.2b8. For 2.x we include
11796 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
11797 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
11798 [Dean Gaudet] PR#336, PR#340
11800 *) Redirect did not preserve ?query_strings when present in the client's
11801 request. [Dean Gaudet]
11803 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
11805 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
11807 *) Add UnixWare compile/install instructions. [Chuck Murcko]
11809 *) Add mod_example (illustration of API techniques). [Ken Coar]
11811 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
11813 *) Improve handling of directories when filenames have spaces in them.
11816 *) For hosts with multiple IP addresses, try all additional addresses if
11817 necessary to get a connect. Fail only if hostent address list is
11818 exhausted. [Chuck Murcko]
11820 *) More signed/unsigned port fixes. [Dean Gaudet]
11822 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
11825 Changes with Apache 1.2b8
11827 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
11828 to it. [Marc Slemko]
11830 *) The addition of <Location> and <File> directives made the
11831 sub_req_lookup_simple() function bogus, so we now handle
11832 the special cases directly. [Dean Gaudet]
11834 *) We now try to log where the server is dumping core when a fatal
11835 signal is received. [Ken Coar]
11837 *) Improved lingering_close by adding a special timeout, removing the
11838 spurious log messages, removing the nonblocking settings (they
11839 are not needed with the better timeout), and adding commentary
11840 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
11841 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
11843 *) Send error messages about setsockopt failures to the server error
11844 log instead of stderr. [Roy Fielding]
11846 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
11848 *) Stopgap solution for CGI 3-second delay with server-side includes: if
11849 processing a subrequest, allocate memory from r->main->pool instead
11850 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
11851 in the middle of an SSI request. [Dean Gaudet] PR #122
11853 *) Fixed status of response when POST is received for a nonexistent URL
11854 (was sending 405, now 404) and when any method is sent with a
11855 full-URI that doesn't match the server and the server is not acting
11856 as a proxy (was sending 501, now 403). [Roy Fielding]
11858 *) Host port changed to unsigned short. [Ken Coar] PR #276
11860 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
11862 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
11864 *) Report extra info from errno with many errors that cause httpd to exit.
11865 spawn_child, popenf, and pclosef now have valid errno returns in the
11866 event of an error. Correct problems where errno was stomped on
11867 before being reported. [Dean Gaudet]
11869 *) In the proxy, if the cache filesystem was full, garbage_coll() was
11870 never called, and thus the filesystem would remain full indefinitely.
11871 We now also remove incomplete cache files left if the origin server
11872 didn't send a Content-Length header and either the client has aborted
11873 transfer or bwrite() to client has failed. [Petr Lampa]
11875 *) Fixed the handling of module and script-added header fields.
11876 Improved the interface for sending header fields and reduced
11877 the duplication of code between sending okay responses and errors.
11878 We now always send both headers_out and err_headers_out, and
11879 ensure that the server-reserved fields are not being overridden,
11880 while not overriding those that are not reserved. [Roy Fielding]
11882 *) Moved transparent content negotiation fields to err_headers_out
11883 to reflect above changes. [Petr Lampa]
11885 *) Fixed the determination of whether or not we should make the
11886 connection persistent for all of the cases where some other part
11887 of the server has already indicated that we should not. Also
11888 improved the ordering of the test so that chunked encoding will
11889 be set whenever it is desired instead of only when KeepAlive
11890 is enabled. Added persistent connection capability for most error
11891 responses (those that do not indicate a bad input stream) when
11892 accessed by an HTTP/1.1 client. [Roy Fielding]
11894 *) Added missing timeouts for sending header fields, error responses,
11895 and the last chunk of chunked encoding, each of which could have
11896 resulted in a process being stuck in write forever. Using soft_timeout
11897 requires that the sender check for an aborted connection rather than
11898 continuing after an EINTR. Timeouts that used to be initiated before
11899 send_http_header (and never killed) are now initiated only within or
11900 around the routines that actually do the sending, and not allowed to
11901 propagate above the caller. [Roy Fielding]
11903 *) mod_auth_anon required an @ or a . in the email address, not both.
11906 *) per_dir_defaults weren't set correctly until directory_walk for
11907 name-based vhosts. This fixes an obscure bug with the wrong config
11908 info being used for vhosts that share the same ip as the server.
11911 *) Improved generation of modules/Makefile to be more generic for
11912 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
11914 *) Generate makefile dependency for Configuration based on the actual
11915 name given when running the Configure process. [Dean Gaudet]
11917 *) Fixed problem with vhost error log not being set prior to
11918 initializing virtual hosts. [Dean Gaudet]
11920 *) Fixed infinite loop when a trailing slash is included after a type map
11921 file URL (extra path info). [Petr Lampa]
11923 *) Fixed server status updating of per-connection counters. [Roy Fielding]
11925 *) Add documentation for DNS issues (reliability and security), and try
11926 to explain the virtual host matching process. [Dean Gaudet]
11928 *) Try to continue gracefully by disabling the vhost if a DNS lookup
11929 fails while parsing the configuration file. [Dean Gaudet]
11931 *) Improved calls to setsockopt. [Roy Fielding]
11933 *) Negotiation changes: Don't output empty content-type in variant list;
11934 Output charset in variant list; Return sooner from handle_multi() if
11935 no variants found; Add handling of '*' wildcard in Accept-Charset.
11936 [Petr Lampa and Paul Sutton]
11938 *) Fixed overlaying of request/sub-request notes and headers in
11939 mod_negotiation. [Dean Gaudet]
11941 *) If two variants' charset quality are equal and one is the default
11942 charset (iso-8859-1), then prefer the variant that was specifically
11943 listed in Accept-Charset instead of the default. [Petr Lampa]
11945 *) Memory allocation problem in push_array() -- it would corrupt memory
11946 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
11948 *) invoke_handler() doesn't handle mime arguments in content-type
11949 [Petr Lampa] PR#160
11951 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
11954 *) Fixed problem with ErrorDocument not working for virtual hosts
11955 due to one of the performance changes in 1.2b7. [Dean Gaudet]
11957 *) Log an error message if we get a request header that is too long,
11958 since it may indicate a buffer overflow attack. [Marc Slemko]
11960 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
11961 not reject URLs without a double-slash, as per RFC2068 section 3.2.
11962 [Ken Coar] PR #146, #187
11964 *) Added table entry placeholder for new header_parser callback
11965 in all of the distributed modules. [Ken Coar] PR #191
11967 *) Allow for cgi files without the .EXE extension on them under OS/2.
11968 [Garey Smiley] PR #59
11970 *) Fixed error message when resource is not found and URL contains
11971 path info. [Petr Lampa and Dean Gaudet] PR #40
11973 *) Fixed user and server confusion over what should be a virtual host
11974 and what is the main server, resulting in access to something
11975 other than the name defined in the virtualhost directive (but
11976 with the same IP address) failing. [Dean Gaudet]
11978 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
11979 AIX; improves the redirection stuff to enable the users to generally
11980 redirect to http, https, gopher and ftp; added TIME variable for
11981 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
11982 special patterns >STRING, <STRING and =STRING to RewriteCond, which
11983 can be used in conjunction with %{TIME} or other variables to create
11984 time-dependent rewriting rules. [Ralf S. Engelschall]
11986 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
11987 Module authors may need to adjust their code for proper cleanup to take
11988 place (that is, call note_cleanups_for_fd()). This change fixes problems
11989 with file descriptors being erroneously closed when the proxy module was
11990 in use. [Ben Laurie]
11992 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
11993 initgroups() to hose the group information needed for later
11994 comparisons. [Randy Terbush]
11996 *) Remove unnecessary call to va_end() in create_argv() which
11997 caused a SEGV on some systems.
11999 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
12002 *) Clear memory allocated for listeners. [Randy Terbush]
12004 *) Improved handling of IP address as a virtualhost address and
12005 introduced "_default_" as a synonym for the default vhost config.
12006 [Dean Gaudet] PR #212
12008 Changes with Apache 1.2b7
12010 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
12012 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
12014 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
12015 - replace protocol response numbers with symbols
12016 - save variant-list into main request notes
12017 - free allocated memory from subrequests
12018 - merge notes, headers_out and err_headers_out
12020 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
12021 "HTTP/#.# ###*" to be more lenient about what we accept.
12024 *) more proxy FTP bug fixes:
12025 - Changed send_dir() to remove user/passwd from displayed URL.
12026 - Changed login error messages to be more descriptive.
12027 - remove setting of SO_DEBUG socket option
12028 - Make ftp_getrc() more lenient about multiline responses,
12029 specifically, 230 responses which don't have continuation 230-
12030 on each line). These seem to be all NT FTP servers, and while
12031 perhaps questionable, they appear to be legal by RFC 959.
12032 - Add missing kill_timeout() after transfer to user completes.
12035 *) Fixed problem where a busy server could hang when restarting
12036 after being sent a SIGHUP due to child processes not exiting.
12039 *) Modify mod_include escaping so a '\' only signifies an escaped
12040 character if the next character is one that needs
12041 escaping. [Ben Laurie]
12043 *) Eliminated possible infinite loop in mod_imap when relative URLs are
12044 used with a 'base' directive that does not have a '/' in it.
12045 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
12047 *) Reduced the default timeout from 1200 seconds to 300, and the
12048 one in the sample configfile from 400 to 300. [Marc Slemko]
12050 *) Stop vbprintf from crashing if given a NULL string pointer;
12051 print (null) instead. [Ken Coar]
12053 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
12054 [Marc Slemko and Roy Fielding]
12056 *) Fixed problem with mod_cgi-generated internal redirects trying to
12057 read the request message-body twice. [Archie Cobbs and Roy Fielding]
12059 *) Reduced timeout on lingering close, removed possibility of a blocked
12060 read causing the child to hang, and stopped logging of errors if
12061 the socket is not connected (reset by client). [Roy Fielding]
12063 *) Rearranged main child loop to remove duplication of code in
12064 select/accept and keep-alive requests, fixed several bugs regarding
12065 checking scoreboard_image for exit indication and failure to
12066 account for all success conditions and trap all error conditions,
12067 prevented multiple flushes before closing the socket; close the entire
12068 socket buffer instead of just one descriptor, prevent logging of
12069 EPROTO and ECONNABORTED on platforms where supported, and generally
12070 improved readability. [Roy Fielding]
12072 *) Extensive performance improvements. Cleaned up inefficient use of
12073 auto initializers, multiple is_matchexp calls on a static string,
12074 and excessive merging of response_code_strings. [Dean Gaudet]
12076 *) Added double-buffering to mod_include to improve performance on
12077 server-side includes. [Marc Slemko]
12079 *) Several fixes for suexec wrapper. [Randy Terbush]
12080 - Make wrapper work for files on NFS filesystem.
12081 - Fix portability problem of MAXPATHLEN.
12082 - Fix array overrun problem in clean_env().
12083 - Fix allocation of PATH environment variable
12085 *) Removed extraneous blank line is description of mod_status chars.
12088 *) Logging of errors from the call_exec routine simply went nowhere,
12089 since the logfile fd has been closed, so now we send them to stderr.
12090 [Harald T. Alvestrand]
12092 *) Fixed core dump when DocumentRoot is a CGI.
12093 [Ben Laurie, reported by <geddis tesserae.com>]
12095 *) Fixed potential file descriptor leak in mod_asis; updated it and
12096 http_core to use pfopen/pfclose instead of fopen/fclose.
12097 [Randy Terbush and Roy Fielding]
12099 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
12100 as the DEC Alpha which is 64-bit but uses 32-bit ints.
12101 [Dean Gaudet and Ken Coar]
12103 *) Return a 302 response code to the client when sending a redirect
12104 due to a missing trailing '/' on a directory instead of a 301; now
12105 it is cacheable. [Markus Gyger]
12107 *) Fix condition where, if a bad directive occurs in .htaccess, and
12108 sub_request() goes first to this directory, then log_reason() will
12109 SIGSEGV because it doesn't have initialized r->per_dir_config.
12110 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
12112 *) Fix handling of lang_index in is_variant_better(). This was
12113 causing problems which resulted in the server sending the
12114 wrong language document in some cases. [Petr Lampa]
12116 *) Remove free() from clean_env() in suexec wrapper. This was nuking
12117 the clean environment on some systems.
12119 *) Tweak byteserving code (e.g. serving PDF files) to work around
12120 bugs in Netscape Navigator and Microsoft Internet Explorer.
12121 Emit Content-Length header when sending multipart/byteranges.
12124 *) Port to HI-UX/WE2. [Nick Maclaren]
12126 *) Port to HP MPE operating system for HP 3000 machines
12127 [Mark Bixby <markb cccd.edu>]
12129 *) Fixed bug which caused a segmentation fault if only one argument
12130 given to RLimit* directives. [Ed Korthof]
12132 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
12134 *) Improved buffered output to the client by delaying the flush decision
12135 until the BUFF code is actually about to read the next request.
12136 This fixes a problem introduced in 1.2b5 with clients that send
12137 an extra CRLF after a POST request. Also improved chunked output
12138 performance by combining writes using writev() and removing as
12139 many bflush() calls as possible. NOTE: Platforms without writev()
12140 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
12141 or Configure, unless we have already done so. [Dean Gaudet]
12143 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
12145 *) Fixed mod_info output corruption bug introduced by buffer overflow
12146 fixes. [Dean Gaudet]
12148 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
12149 for the special case of a 304 response. [Paul Sutton]
12151 *) Improved handling of TRACE method by bypassing normal method handling
12152 and header parsing routines; fixed Allow response to always allow TRACE.
12155 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
12157 *) Cleaned-up some of the generated HTML. [Ken Coar]
12159 Changes with Apache 1.2b6
12161 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
12163 *) Fix typo introduced in fix for potential infinite loop around
12164 accept() in child_main(). This change caused the rev to 1.2b6.
12165 1.2b5 was never a public beta.
12167 Changes with Apache 1.2b5
12169 *) Change KeepAlive semantics (On|Off instead of a number), add
12170 MaxKeepAliveRequests directive. [Alexei Kosut]
12172 *) Various NeXT compilation patches, as well as a change in
12173 regex/regcomp.c since that file also used a NEXT define.
12176 *) Allow * to terminate the end of a directory match in mod_dir.
12177 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
12179 *) Don't call can_exec() if suexec_enabled. Calling this requires
12180 scripts executed by the suexec wrapper to be world executable, which
12181 defeats one of the advantages of running the wrapper. [Randy Terbush]
12183 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
12186 *) Migration from sprintf() to snprintf() to avoid buffer
12187 overflows. [Marc Slemko]
12189 *) Provide portable snprintf() implementation (ap_snprintf)
12190 as well as *cvt family. [Jim Jagielski]
12192 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
12195 *) Remove mod_fastcgi.c from the distribution. This module appears
12196 to be maintained more through the Open Market channels and should
12197 continue to be easily available at http://www.fastcgi.com/
12199 *) Fixed bug in modules/Makefile that wouldn't allow building in more
12200 than one subdirectory (or cleaning, either). [Jeremy Laidman]
12202 *) mod_info assumed that the config files were relative to ServerRoot.
12205 *) CGI scripts called as an error document resulting from failed
12206 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
12208 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
12211 *) Properly check errno to prevent display of a directory index
12212 when server receives a long enough URL to confuse stat().
12215 *) Several security enhancements to suexec wrapper. It is _highly_
12216 recommended that previously installed versions of the wrapper
12217 be replaced with this version. [Randy Terbush, Jason Dour]
12219 - ~user execution now properly restricted to ~user's home
12220 directory and below.
12221 - execution restricted to UID/GID > 100
12222 - restrict passed environment to known variables
12223 - call setgid() before initgroups() (portability fix)
12224 - remove use of setenv() (portability fix)
12226 *) Add HTTP/1.0 response forcing. [Ben Laurie]
12228 *) Add access control via environment variables. [Ben Laurie]
12230 *) Add rflush() function. [Alexei Kosut]
12232 *) remove duplicate pcalloc() call in new_connection().
12234 *) Fix incorrect comparison which could allow number of children =
12235 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
12236 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
12238 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
12239 AIX PS/2, CONVEXOS. [Jim Jagielski]
12241 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
12242 It's more portable. [Martin Kraemer]
12244 *) Replace references to make in Makefile.tmpl with $(MAKE).
12247 *) Add ProxyBlock directive w/IP address caching. Add IP address
12248 caching to NoCache directive as well. ProxyBlock works with all
12249 handlers; NoCache now also works with FTP for anonymous logins.
12250 Still more code cleanup. [Chuck Murcko]
12252 *) Add "header parse" API hook [Ben Laurie]
12254 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
12256 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
12258 *) Correctly allow access and auth directives in <Files> sections in
12259 server config files. [Alexei Kosut]
12261 *) Fix bug with ServerPath that could cause certain files to be not
12262 found by the server. [Alexei Kosut]
12264 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
12265 double-quote from text and so that it properly checks for unsupported
12266 status codes using the new index_of_response interface. [Roy Fielding]
12268 *) Multiple fixes to the lingering_close code in order to avoid being
12269 interrupted by a stray timeout, to avoid lingering on a connection
12270 that has already been aborted or never really existed, to ensure that
12271 we stop lingering as soon as any error condition is received, and to
12272 prevent being stuck indefinitely if the read blocks. Also improves
12273 reporting of error conditions. [Marc Slemko and Roy Fielding]
12275 *) Fixed initialization of parameter structure for sigaction.
12276 [<mgyger itr.ch>, Adrian Filipi-Martin]
12278 *) Fixed reinitializing the parameters before each call to accept and
12279 select, and removed potential for infinite loop in accept.
12280 [Roy Fielding, after useful PR from <adrian virginia.edu>]
12282 *) Fixed condition where, if a child fails to fork, the scoreboard would
12283 continue to say SERVER_STARTING forever. Eventually, the main process
12284 would refuse to start new children because count_idle_servers() will
12285 count those SERVER_STARTING entries and will always report that there
12286 are enough idle servers. [Phillip Vandry]
12288 *) Fixed bug in bcwrite regarding failure to account for partial writes.
12289 Avoided calling bflush() when the client is pipelining requests.
12290 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
12292 *) Added description of "." mode in server-status [Jim Jagielski]
12294 Changes with Apache 1.2b4
12296 *) Fix possible race condition in accept_mutex_init() that
12297 could leave a small security hole open allowing files to be
12298 overwritten in cases where the server UID has write permissions.
12301 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
12303 *) Fix portablity problem in util_script where ARG_MAX may not be
12304 defined for some systems.
12306 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
12309 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
12310 style magic #! token for better script portability. [Garey Smiley]
12312 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
12313 execution for ~userdir CGI. [Jason Dour]
12315 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
12317 *) Fix month off by one in suexec wrapper logging.
12319 Changes with Apache 1.2b3:
12321 *) Fix error in mod_cgi which could cause resources not to be properly
12322 freed, or worse. [Dean Gaudet]
12324 *) Fix find_string() NULL pointer dereference. [Howard Fear]
12326 *) Add set_flag_slot() at the request of Dirk and others.
12329 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
12331 *) Add changes to improve the error message given for invalid
12332 ServerName parameters. [Dirk vanGulik]
12334 *) Add "Authoritative" directive for Auth modules that don't
12335 currently have it. This gives admin control to assign authoritative
12336 control to an authentication scheme and allow "fall through" for
12337 those authentication modules that aren't "Authoritative" thereby
12338 allowing multiple authentication mechanisms to be chained.
12341 *) Remove requirement for ResourceConfig/AccessConfig if not using
12342 the three config file layout. [Randy Terbush]
12344 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
12346 *) Changes to suexec wrapper to fix the following problems:
12347 1. symlinked homedirs will kill ~userdirs.
12348 2. initgroups() on Linux 2.0.x clobbers gr->grid.
12349 3. CGI command lines paramters problems
12350 4. pw-pwdir for "docroot check" still the httpd user's pw record.
12351 [Randy Terbush, Jason Dour]
12353 *) Change create_argv() to accept variable arguments. This fixes
12354 a problem where arguments were not getting passed to the CGI via
12355 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
12357 *) Collapse multiple slashes in path URLs to properly apply
12358 handlers defined by <Location>. [Alexei Kosut]
12360 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
12362 *) Improve the accuracy of request duration timings by setting
12363 r->request_time in read_request_line() instead of read_request().
12366 *) Reset timeout while reading via get_client_block() in mod_cgi.c
12367 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
12369 *) Add the ability to pass different Makefile.tmpl files to Configure
12370 using the -make flag. [Rob Hartill]
12372 *) Fix coredump triggered when sending a SIGHUP to the server caused
12373 by an assertion failure, in turn caused by an uninitialised field in a
12377 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
12378 PATH_INFO from previous versions of Apache (in certain situations,
12379 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
12380 [later removed in 1.2b11]
12382 *) Add rwrite() function to API to allow for sending strings of
12383 arbitrary length. [Doug MacEachern]
12385 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
12387 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
12388 NeXT. [Jim Jagielski]
12390 *) Removed recent modification to promote the status code on internal
12391 redirects, since the correct fix was to change the default log format
12392 in mod_log_config so that it outputs the original status. [Rob Hartill]
12394 Changes with Apache 1.2b2:
12396 *) Update set_signals() to use sigaction() for setting handlers.
12397 This appears to fix a re-entrant problem in the seg_fault()
12398 bus_error() handlers. [Randy Terbush]
12400 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
12402 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
12404 *) proxy_http.c bugfixes: [Chuck Murcko]
12405 1) fixes possible NULL pointer reference w/NoCache
12406 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
12407 host would cache nothing if it was in the local domain,
12408 and the local domain was in the NoCache list)
12409 3) Adds Host: header when not available
12410 4) Some code cleanup and clarification
12412 *) mod_include.c bugfixes:
12413 1) Fixed an ommission that caused include variables to not
12414 be parsed in config errmsg directives [Howard Fear]
12415 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
12416 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
12417 4) Allow backslash-escaping to all quoted text
12418 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
12419 5) Pass variable to command line if not set in XSSI's env
12422 *) Fix infinite loop when processing Content-language lines in
12423 type-map files. [Alexei Kosut]
12425 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
12427 *) Fixed problem in set_[user|group] that prevented CGI execution
12428 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
12430 *) Added PORTING information file. [Jim Jagielski]
12432 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
12434 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
12436 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
12437 USE_FCNTL_SERIALIZED_ACCEPT was intended.
12439 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
12440 which caused problems of systems where socket s_addr is >32bits.
12442 *) Added comment to explain (r->chunked = 1) side-effect in
12443 http_protocol.c [Roy Fielding]
12445 *) Replaced use of index() in mod_expires.c with more appropriate
12446 and portable isdigit() test. [Ben Laurie]
12448 *) Updated Configure for ...
12449 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
12450 *-dg-dgux* (bad pattern match)
12451 QNX (DEF_WANTHSREGEX=yes)
12452 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
12454 *-unixware211 (new)
12455 and added some user diagnostic info. [Ben Laurie]
12457 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
12458 for better portability. [Jim Jagielski]
12460 *) Updated helpers/GuessOS for ...
12461 SCO 5 (recognize minor releases)
12462 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
12463 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
12464 IRIX64 (-sgi-irix64)
12465 ULTRIX (-unknown-ultrix)
12466 SINIX (-whatever-sysv4)
12467 NCR Unix (-ncr-sysv4)
12468 and fixed something in helpers/PrintPath [Ben Laurie]
12470 Changes with Apache 1.2b1
12472 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
12474 Changes with Apache 1.1.1
12476 *) Fixed bug where Cookie module would make two entries in the
12477 logfile for each access [Mark Cox]
12479 *) Fixed bug where Redirect in .htaccess files would cause memory
12480 leak. [Nathan Neulinger]
12482 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
12484 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
12486 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
12488 Changes with Apache 1.1.0
12490 *) Bring NeXT support up to date. [Takaaki Matsumoto]
12492 *) Bring QNX support up to date. [Ben Laurie]
12494 *) Make virtual hosts default to main server keepalive parameters.
12495 [Alexei Kosut, Ben Laurie]
12497 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
12499 *) Fix missing address family for connect, also remove unreachable statement
12500 in mod_proxy. [Ben Laurie]
12502 *) mod_env now turned on by default in Configuration.tmpl.
12504 *) Bugs which were fixed:
12505 a) yet more mod_proxy bugs [Ben Laurie]
12506 b) CGI works again with inetd [Alexei Kosut]
12507 c) Leading colons were stripped from passwords [<osm interguide.com>]
12508 d) Another fix to multi-method Limit problem [<jk tools.de>]
12510 Changes with Apache 1.1b4
12512 *) r->bytes_sent variable restored. [Robert Thau]
12514 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
12516 *) More possibly unsecure programs removed from the support directory.
12518 *) More mod_auth_msql authentication improvements.
12520 *) VirtualHosts based on Host: headers no longer conflict with the
12523 *) OS/2 compatibility enhancements. [Gary Smiley]
12525 *) POST now allowed to directory index CGI scripts.
12527 *) Actions now work with files of the default type.
12529 *) Bugs which were fixed:
12530 a) more mod_proxy bugs
12531 b) early termination of inetd requests
12532 c) compile warnings on several systems
12533 d) problems when scripts stop reading output early
12535 Changes with Apache 1.1b3
12537 *) Much of cgi-bin and all of cgi-src has been removed, due to
12538 various security holes found and that we could no longer support
12541 *) The "Set-Cookie" header is now special-cased to not merge multiple
12542 instances, since certain popular browsers can not handle multiple
12543 Set-Cookie instructions in a single header. [Paul Sutton]
12545 *) rprintf() added to buffer code, occurrences of sprintf removed.
12548 *) CONNECT method for proxy module, which means tunneling SSL should work.
12549 (No crypto needed) Also a NoCache config directive.
12551 *) Several API additions: pstrndup(), table_unset() and get_token()
12552 functions now available to modules.
12554 *) mod_imap fixups, in particular Location: headers are now complete
12557 *) New "info" module which reports on installed module set through a
12558 special URL, a la mod_status.
12560 *) "ServerPath" directive added - allows for graceful transition
12561 for Host:-header-based virtual hosts.
12563 *) Anonymous authentication module improvements.
12565 *) MSQL authentication module improvements.
12567 *) Status module design improved - output now table-based. [Ben Laurie]
12569 *) htdigest utility included for use with digest authentication
12572 *) mod_negotiation: Accept values with wildcards to be treated with
12573 less priority than those without wildcards at the same quality
12574 value. [Alexei Kosut]
12576 *) Bugs which were fixed:
12577 a) numerous mod_proxy bugs
12578 b) CGI early-termination bug [Ben Laurie]
12579 c) Keepalives not working with virtual hosts
12580 d) RefererIgnore problems
12581 e) closing fd's twice in mod_include (causing core dumps on
12582 Linux and elsewhere).
12584 Changes with Apache 1.1b2
12587 a) core dumps in mod_digest
12588 b) truncated hostnames/ip address in the logs
12589 c) relative URL's in mod_imap map files
12591 Changes with Apache 1.1b1
12593 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12595 Changes with Apache 1.0.3
12597 *) Internal redirects which occur in mod_dir.c now preserve the
12598 query portion of a request (the bit after the question mark).
12601 *) Escape active characters '<', '>' and '&' in html output in
12602 directory listings, error messages and redirection links.
12605 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12607 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12610 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12612 *) Reset timeout timer after each successful fwrite() to the network.
12613 This patch adds a reset_timeout() procedure that is called by
12614 send_fd() to reset the timeout ever time data is written to the net.
12617 *) timeout() signal handler now checks for SIGPIPE and reports
12618 lost connections in a more user friendly way. [Rob Hartill]
12620 *) Location of the "scoreboard" file which used to live in /tmp is
12621 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12622 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12624 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12626 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12627 which caused a SEGV with cookies enabled
12629 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12632 *) Log the UNIX textual error returned by some system calls, in
12633 particular errors from accept() [David Robinson]
12635 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12637 Changes with Apache 1.0.2
12639 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12640 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12642 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12645 *) past changes to http_config.c to only use the
12646 setrlimit function on systems defining RLIMIT_NOFILE
12647 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12648 for SUNOS and prototypes the needed functions.
12650 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12653 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12655 *) Merge multiple headers from CGI scripts instead of taking last
12656 one. [David Robinson]
12658 *) Add support for SCO 5. [Ben Laurie]
12660 Changes with Apache 1.0.1
12662 *) Silence mod_log_referer and mod_log_agent if not configured
12665 *) Recursive includes can occur if the client supplies PATH_INFO data
12666 and the server provider uses relative links; as file.html
12667 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
12669 *) The replacement for initgroups() did not call {set,end}grent(). This
12670 had two implications: if anything else used getgrent(), then
12671 initgroups() would fail, and it was consuming a file descriptor.
12674 *) On heavily loaded servers it was possible for the scoreboard to get
12675 out of sync with reality, as a result of a race condition.
12676 The observed symptoms are far more Apaches running than should
12677 be, and heavy system loads, generally followed by catastrophic
12678 system failure. [Ben Laurie]
12680 *) Fix typo in license. [David Robinson]
12682 Changes with Apache 1.0.0 23 Nov 1995
12684 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
12686 Changes with Apache 0.8.16 05 Nov 1995
12688 *) New man page for 'httpd' added to support directory [David Robinson]
12690 *) .htgroup files can have more than one line giving members for a
12691 given group (each must have the group name in front), for NCSA
12692 back-compatibility [Robert Thau]
12694 *) Mutual exclusion around accept() is on by default for SVR4 systems
12695 generally, since they generally can't handle multiple processes in
12696 accept() on the same socket. This should cure flaky behavior on
12697 a lot of those systems. [David Robinson]
12699 *) AddType, AddEncoding, and AddLanguage directives take multiple
12700 extensions on a single command line [David Robinson]
12702 *) UserDir can be disabled for a given virtual host by saying
12703 "UserDir disabled" in the <VirtualHost> section --- it was a bug
12704 that this didn't work. [David Robinson]
12706 *) Compiles on QNX [Ben Laurie]
12708 *) Corrected parsing of ctime time format [David Robinson]
12710 *) httpd does a perror() before exiting if it can't log its pid
12711 to the PidFile, to make diagnosing the error a bit easier.
12714 *) <!--#include file="..."--> can no longer include files in the
12715 parent directory, for NCSA back-compatibility. [David Robinson]
12717 *) '~' is *not* escaped in URIs generated for directory listings
12720 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
12722 *) Fixed bug involving handling URIs with escaped %-characters
12723 in redirects [David Robinson]
12725 Changes with Apache 0.8.15 14 Oct 1995
12727 *) Switched to new, simpler license
12729 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
12731 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
12733 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
12735 *) Correctly handles internal redirects to files with names containing '%'
12738 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
12740 *) Use geteuid() rather than getuid() to see if we have root privilege,
12741 so that server correctly resets privilege if run setuid root. [Andrew
12744 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
12747 *) Fix relative URLs in imagemap files [Randy Terbush]
12749 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
12752 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
12753 entries all name the same one. [David Robinson]
12755 *) Fix directory listings with filenames containing unusual characters
12758 *) Better URI-escaping for generated URIs in directories with filenames
12759 containing unusual characters [Ben Laurie]
12761 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
12763 *) Unblock alarms on error return from spawn_child() [David Robinson]
12765 *) Sample Config files have extra note for SCO users [Ben Laurie]
12767 *) Configuration has note for HP-UX users [Rob Hartill]
12769 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
12771 *) Nuked bogus #define in httpd.h [David Robinson]
12773 *) Better test for whether a system has setrlimit() [David Robinson]
12775 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
12777 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
12780 Changes with Apache 0.8.14 19 Sep 1995
12782 *) Compiles on SCO ODT 3.0 [Ben Laurie]
12784 *) AddDescription works (better) [Ben Laurie]
12786 *) Leaves an intelligible error diagnostic when it can't set group
12787 privileges on standalone startup [Andrew Wilson]
12789 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
12790 that machine, which claims to be BSD but does not support RLIMIT.
12793 *) gcc -Wall no longer complains about an unused variable when util.c
12794 is compiled with -DMINIMAL_DNS [Andrew Wilson]
12796 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
12798 Changes with Apache 0.8.13 07 Sep 1995
12800 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
12802 *) Have built-in imagemap code recognize & honor Point directive [James
12805 *) Generate cleaner directory listings in directories with a mix of
12806 long and short filenames [Rob Hartill]
12808 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
12810 *) Properly default ServerName for virtual servers [Robert Thau]
12812 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
12813 Paul Richards and a cast of thousands...]
12815 *) On self-identified BSD systems (we don't try to guess any more),
12816 allocate a few extra file descriptors per virtual host with setrlimit,
12817 if we can, to avoid running out. [Randy Terbush]
12819 *) Write 22-character lock file name into buffer with enough space
12820 on startup [Konstantin Olchanski]
12822 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
12825 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
12827 *) Suppress -Wall warning by initializing variable in negotiation code
12828 [Tobias Weingartner]
12830 Changes with Apache 0.8.12 31 Aug 1995
12832 *) Doesn't pause three seconds after including a CGI script which is
12833 too slow to die off (this is done by not even trying to kill off
12834 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
12835 after the entire document has been processed). [Robert Thau]
12837 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
12839 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
12841 *) Allows .htaccess files to override <Directory> sections naming the
12842 same directory [David Robinson]
12844 *) Removed an efficiency hack in sub_req_lookup_uri which was
12845 causing certain extremely marginal cases (e.g., ScriptAlias of a
12846 *particular* index.html file) to fail. [David Robinson]
12848 *) Doesn't log an error when the requested URI requires
12849 authentication, but no auth header line was supplied by the
12850 client; this is a normal condition (the client doesn't no auth is
12851 needed here yet). [Robert Thau]
12853 *) Behaves more sanely when the name server loses its mind [Sean Welch]
12855 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
12857 *) RFC931 code no longer passes out name of prior clients on current
12858 requests if the current request came from a server that doesn't
12859 do RFC931. [David Robinson]
12861 *) Configuration script accepts "Module" lines with trailing whitespace.
12864 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
12866 *) Cleaned up comments in mod_cgi.c [Robert Thau]
12868 Changes with Apache 0.8.11 24 Aug 1995
12870 *) Wildcard <Directory> specifications work. [Robert Thau]
12872 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
12874 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
12875 the file being requested itself, in addition to the directories leading
12876 up to it. [Robert Thau]
12878 *) Logs access failures due to symlink checks or invalid client address
12879 in the error log [Roy Fielding, Robert Thau]
12881 *) Symlink checks deal correctly with systems where lstat of
12882 "/path/to/some/link/" follows the link. [Thau, Fielding]
12884 *) Doesn't reset DirectoryIndex to 'index.html' when
12885 other directory options are set in a .htaccess file. [Robert Thau]
12887 *) Clarified init code and nuked bogus warning in mod_access.c
12888 [Florent Guillaume]
12890 *) Corrected several directives in sample srm.conf
12891 --- includes corrections to directory indexing icon-related directives
12892 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
12893 icons for encodings right, and turning on AddEncoding by default).
12896 *) Corrected descriptions of args to AddIcon and AddAlt in command table
12899 *) INSTALL & README mention "contributed modules" directory [Brian
12902 *) Fixed English in the license language... "for for" --> "for".
12905 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
12906 mod_alias.c, merging it almost completely with handling of Alias, and
12907 adding a 'notes' field to the request_rec which allows the CGI module
12908 to discover whether the Alias module has put this request through
12909 ScriptAlias (which it needs to know for back-compatibility, as the old
12910 NCSA code did not check Options ExecCGI in ScriptAlias directories).
12913 Changes with Apache 0.8.10 18 Aug 1995
12915 *) AllowOverride applies to the named directory, and not just
12916 subdirectories. [David Robinson]
12918 *) Do locking for accept() exclusion (on systems that need it)
12919 using a special file created for the purpose in /usr/tmp, and
12920 not the error log; using the error log causes real problems
12921 if it's NFS-mounted; this is known to be the cause of a whole
12922 lot of "server hang" problems with Solaris. [David Robinson;
12923 thanks to Merten Schumann for help diagnosing the problem].
12925 Changes with Apache 0.8.9 12 Aug 1995
12927 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
12929 *) Nested includes see environment variables of the including document,
12930 for NCSA bug-compatibility (some sites have standard footer includes
12931 which try to print out the last-modified date). [Eric Hagberg/Robert
12934 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
12935 URI as a CGI script, even if it would have been treated as something
12936 else if requested directly, for NCSA back-compatibility. (Note that
12937 this means that people who know the name of the script can see the
12938 code just by asking for it). [Robert Thau]
12940 *) New version of dbmmanage script included in support directory as
12943 *) Check if scoreboard file couldn't be opened, and say so, rather
12944 then going insane [David Robinson]
12946 *) POST to CGI works on A/UX [Jim Jagielski]
12948 *) AddIcon and AddAlt commands work properly [Rob Hartill]
12950 *) NCSA server push works properly --- the Arena bug compatibility
12951 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
12952 if you still want the workaround). [Rob Hartill]
12954 *) If client didn't submit any Accept-encodings, ignore encodings in
12955 content negotiation. (NB this will all have to be reworked anyway
12956 for the new HTTP draft). [Florent Guillaume]
12958 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
12960 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
12962 *) Give Redirect priority over Alias, for NCSA bug compatibility
12965 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
12966 paralleling earlier bug fix for CGI [David Robinson]
12968 *) If DBM auth is improperly configured, report a server error and don't
12971 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
12972 it seems to work well enough without it (even in a 10 hits/sec
12973 workout), and the overhead for the locking under A/UX is
12974 alarmingly high (though it is very low on other systems).
12975 [Eric Hagberg, Jim Jagielski]
12977 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
12979 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
12980 Behlendorf/Eric Hagberg]
12982 *) More improvements to default Configuration for A/UX [Jim Jagielski]
12984 *) Compiles clean on NEXT [Rob Hartill]
12986 *) Compiles clean on SGI [Robert Thau]
12988 Changes with Apache 0.8.8 08 Aug 1995
12990 *) SunOS library prototypes now never included unless explicitly
12991 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
12992 people using GNU libc on SunOS are screwed by prototypes for the
12995 (Those who wish to compile clean with gcc -Wall on a standard
12996 SunOS setup need the prototypes, and may obtain them using
12997 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
12998 with nonstandard libraries are presumably competent to make their
13001 *) Strips trailing '/' characters off both args to the Alias command,
13002 to make 'Alias /foo/ /bar/' work.
13004 Changes with Apache 0.8.7 03 Aug 1995
13006 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
13007 [reported by David Robinson]
13009 *) Compiles clean on OSF/1 [David Robinson]
13011 *) Added some of the more recent significant changes (AddLanguage stuff,
13012 experimental LogFormat support) to CHANGES file in distribution root
13015 Changes with Apache 0.8.6 02 Aug 1995
13017 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
13018 (If you actually wanted a conditional GET which bypassed the cache, you
13019 couldn't get it). [Reported by Roy Fielding]
13021 *) Properly terminate headers on '304 Not Modified' replies to conditional
13022 GETs --- no browser we can find cares much, but the CERN proxy chokes.
13023 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
13025 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
13027 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
13028 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
13029 and older versions don't set the __SUNPRO_C preprocessor variable). On
13030 all other systems, these are never used anyway. [Reported by Mark Cox].
13032 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
13034 Changes with Apache 0.8.5 01 Aug 1995
13036 *) Added last-minute configurable log experiment, as optional module
13038 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
13039 properly. (One-line fix to http_protocol.c).
13041 *) Work around bogus behavior when reloading from Netscape.
13042 It's Netscape's bug --- for some reason they expect a request with
13043 If-modified-since: to not function as a conditional GET if it also
13044 comes with Pragma: no-cache, which is way out of line with the HTTP
13045 spec (according to Roy Fielding, the redactor).
13047 *) Added parameter to set maximum number of server processes.
13049 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
13052 *) IdentityCheck bugfix [Chuck Murcko].
13054 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
13056 *) More sample config file corrections; add extension to AddType for
13057 *.asis, move AddType generic description to its proper place, and
13058 fix miscellaneous typos. [ Alexei Kosut ]
13060 *) Deleted the *other* reference to the regents from the Berkeley
13061 legal disclaimer (everyplace).
13063 *) Nuked Shambhala name from src/README; had already cleaned it out
13064 of everywhere else.
13066 Changes with Apache 0.8.4
13068 *) Changes to server-pool management parms --- renamed current
13069 StartServers to MinSpareServers, created separate StartServers
13070 parameter which means what it says, and renamed MaxServers to
13071 MaxSpareServers (though the old name still works, for NCSA 1.4
13072 back-compatibility). The old names were generally regarded as
13073 too confusing. Also altered "docs" in sample config files.
13075 *) More improvements to default config files ---
13076 sample directives (commented out) for XBitHack, BindAddress,
13077 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
13078 defaults, AddTypes for send-as-is and imagemap magic types, and
13079 improvements to samples for DirectoryIndex [Alexei Kosut]
13081 *) Yet more improvements to default config files --- changes to
13082 Alexei's sample AddLanguage directives, and sample LanguagePriority
13083 [ Florent Guillaume ]
13085 *) Set config file locations properly if not set in httpd.conf
13088 *) Don't escape URIs in internal redirects multiple times; don't
13089 do that when translating PATH_INFO to PATH_TRANSLATED either.
13092 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
13094 Changes with Apache 0.8.3
13096 *) Edited distribution README to *briefly* summarize installation
13097 procedures, and give a pointer to the INSTALL file in the src/
13100 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
13101 recent NCSA distributions.
13103 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
13104 exist for the same directory, use both and don't segfault. [Reported
13107 *) Proper makefile dependencies [David Robinson]
13109 *) Note (re)starts in error log --- reported by Rob Hartill.
13111 *) Only call no2slash() after get_path_info() has been done, to
13112 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
13113 reported by Andrew Wilson, though this one is probably a real bug]
13115 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
13116 dump core when Referer is not supplied. [Randy Terbush]
13118 *) Lightly edited sample config files to refer people to our documentation
13119 instead of NCSA's, and to list Rob McCool as *original* author (also
13120 deleted his old, and no doubt non-functional email address). Would be
13121 nice to have examples of new features...
13123 Changes with Apache 0.8.2 19 Jul 1995
13125 *) Added AddLanuage code [Florent Guillaume]
13127 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
13129 *) All sorts of problems when MultiViews finds a directory. It would
13130 be nice if mod_dir.c was robust enough to handle that, but for now,
13131 just punt. [reported by Brian Behlendorf]
13133 *) Wait for all children on restart, to make sure that the old socket
13134 is gone and we can reopen it. [reported by Randy Terbush]
13136 *) Imagemap module is enabled in default Configuration
13138 *) RefererLog and UserAgentLog modules properly default the logfile
13141 *) Mark Cox's mod_cookies added to the distribution as an optional
13142 module (commented out in the default Configuration, and noted as
13143 an experiment, along with mod_dld). [Mark Cox]
13145 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
13147 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
13149 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
13151 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
13154 Changes with Apache 0.8.1
13156 *) New imagemap module [Randy Terbush]
13158 *) Replacement referer log module with NCSA-compatible RefererIgnore
13159 [Matthew Gray again]
13161 *) Don't mung directory listings with very long filenames.
13162 [Florent Guillaume]
13164 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
13166 *) New config script. See INSTALL for info. [Robert Thau]
13168 *) Scoreboard mechanism for regulating the number of extant server
13169 processes. MaxServers and StartServers defaults are the same as
13170 for NCSA, but the meanings are slightly different. (Actually,
13171 I should probably lower the MaxServers default to 10).
13173 Before asking for a new connection, each server process checks
13174 the number of other servers which are also waiting for a
13175 connection. If there are more than MaxServers, it quietly dies
13176 off. Conversely, every second, the root, or caretaker, process
13177 looks to see how many servers are waiting for a new connection;
13178 if there are fewer than StartServers, it starts a new one. This
13179 does not depend on the number of server processes already extant.
13180 The accounting is arranged through a "scoreboard" file, named
13181 /tmp/htstatus.*, on which each process has an independent file
13182 descriptor (they need to seek without interference).
13184 The end effect is that MaxServers is the maximum number of
13185 servers on an *inactive* server machine, but more will be forked
13186 off to handle unusually heavy loads (or unusually slow clients);
13187 these will die off when they are no longer needed --- without
13188 reverting to the overhead of full forking operation. There is a
13189 hard maximum of 150 server processes compiled in, largely to
13190 avoid forking out of control and dragging the machine down.
13191 (This is arguably too high).
13193 In my server endurance tests, this mechanism did not appear to
13194 impose any significant overhead, even after I forced it to put the
13195 scoreboard file on a normal filesystem (which might have more
13196 overhead than tmpfs). [Robert Thau]
13198 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
13201 *) Read .htaccess files even in directory with <Directory> section.
13202 (Former incompatibility noted on mailing list, now fixed). [Robert
13205 *) "HEAD /" gives the client a "Bad Request" error message, rather
13206 than trying to send no body *and* no headers. [Cliff Skolnick].
13208 *) Don't produce double error reports for some very obscure cases
13209 mainly involving auth configuration (the "all modules decline to
13210 handle" case which is a sure sign of a server bug in most cases,
13211 but also happens when authentication is badly misconfigured).
13214 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
13215 it's *for*, and this sort of thing really shouldn't be cluttering
13216 up the Makefile). [Robert Thau]
13218 *) Incidental code cleanups in http_main.c --- stop dragging
13219 sa_client around; just declare it where used. [Robert Thau]
13221 *) Another acc-related fix. (It doesn't like const char
13222 in some places...). [Mark Cox]
13224 Changes with Shambhala 0.6.1 13 Jul 1995
13226 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
13227 Also, fixed auth typo in http_protocol.c unmasked by this fix.
13229 *) Compiles clean with acc on SunOS [Paul Sutton]
13231 *) Reordered modules in modules.c so that Redirect takes priority
13232 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
13233 believe it or not, he has an actual site with a ScriptAlias and
13234 a Redirect declared for the *exact same directory*. Even *my*
13235 compatibility fetish wouldn't motivate me to fix this if the fix
13236 required any effort, but it doesn't, so what the hey.
13238 *) Fixed to properly default several server_rec fields for virtual
13239 servers from the corresponding fields in the main server_rec.
13240 [Cliff Skolnick --- 'port' was a particular irritant].
13242 *) No longer kills off nph- child processes before they are
13243 finished sending output. [Matthew Gray]
13245 Changes with Shambhala 0.6.0 10 Jul 1995
13247 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
13248 the connection to the client in an "aborted" state, but otherwise
13249 allow whatever handlers are running to clean up. hard_timeout()s
13250 abort the request in progress completely; anything not tied to some
13251 resource pool cleanup will leak. They're still around because I
13252 haven't yet come up with a more elegant way of handling
13253 timeouts when talking to something that isn't the client. The
13254 default_handler and the dir_handler now use soft timeouts, largely
13255 so I can test the feature. [Robert Thau]
13257 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
13258 the case of log handlers dying prematurely is probably handled VERY
13259 gracelessly at this point, and if the logger stops reading input,
13260 the server will hang. (It is known to correctly restart the
13261 logging process on server restart; this is (should be!) going through
13262 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
13263 script). [Robert Thau]
13265 *) asis files supported (new module). [Robert Thau]
13267 *) IdentityCheck code is compiled in, but has not been tested. (I
13268 don't know anyone who runs identd). [Robert Thau]
13270 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
13271 came in with the request, for NCSA bug-compatibility. [Robert Thau]
13273 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
13275 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
13276 as timeouts are not in scope. [Robert Thau]
13278 *) quoted-string args in config files now handled correctly (doesn't drop
13279 the last character). [Robert Thau; reported by Randy Terbush]
13281 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
13282 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
13284 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
13285 default default type); the former default default behavior when all
13286 type-checkers defaulted had been a core dump. [Paul Sutton]
13288 *) Copy filenames out of the struct dirent when indexing
13289 directories. (On Linux, readdir() returns a pointer to the same
13290 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
13292 Changes with Shambhala 0.5.3 [not released]
13294 *) Default response handler notes "file not found" in the error log,
13295 if the file was not found. [Cliff Skolnick].
13297 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
13298 code no longer sets up bogus PATH_INFO which fakes out the directory
13299 handler). [Cliff Skolnick]
13301 Changes with Shambhala 0.5.2 06 Jul 1995
13303 *) Changes to http_main.c --- root server no longer plays silly
13304 games with SIGCHLD, and so now detects and replaces dying
13305 children. Child processes just die on SIGTERM, without taking
13306 the whole process group with them. Potential problem --- if any
13307 child process refuses to die, we hang in restart.
13308 MaxRequestsPerChild may still not work, but it certainly works
13309 better than it did before this! [Robert Thau]
13311 *) mod_dir.c bug fixes: ReadmeName and HeaderName
13312 work (or work better, at least); over-long description lines
13313 properly terminated. [Mark Cox]
13315 *) http_request.c now calls unescape_url() more places where it
13316 should [Paul Sutton].
13318 *) More directory handling bugs (reported by Cox)
13319 Parent Directory link is now set correctly. [Robert Thau]
13321 Changes with Shambhala 0.5.1 04 Jul 1995
13323 *) Generalized cleanup interface in alloc.c --- any function can be
13324 registered with alloc.c as a cleanup for a resource pool;
13325 tracking of files and file descriptors has been reimplemented in
13326 terms of this interface, so I can give it some sort of a test.
13329 *) More changes in alloc.c --- new cleanup_for_exec() function,
13330 which tracks down and closes all file descriptors which have been
13331 registered with the alloc.c machinery before the server exec()s a
13332 child process for CGI or <!--#exec-->. CGI children now get
13333 started with exactly three file descriptors open. Hopefully,
13334 this cures the problem Rob H. was having with overly persistent
13335 CGI connections. [Robert Thau]
13337 *) Mutual exclusion around the accept() in child_main() --- this is
13338 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
13339 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
13340 This uses fcntl(F_SETLK,...) on the error log descriptor because
13341 flock() on that descriptor won't work on systems which have BSD
13342 flock() semantics, including (I think) Linux 1.3 and Solaris.
13344 This does work on SunOS (when the server is idle, only one
13345 process in the pool is waiting on accept()); it *ought* to work
13346 on the other systems. [Robert Thau]
13348 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
13350 *) sizeof(*sa_client) bugfix from [Rob Hartill]
13352 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
13354 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
13355 be unnecessary if I go to the revised timeout-handling scheme).
13358 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
13359 string) even if none came in with the request. [Robert Thau]
13361 *) CHANGES file added to distribution ;-).
13363 Changes with Shambhala 0.4.5
13365 *) mod_dld --- early dynamic loading support [rst]
13366 *) Add wildcard content handlers for XBITHACK; default_hander now
13367 invoked with that mechanism (as a handler hanging off mod_core) [rst]
13368 *) XBITHACK supported as a wildcard content-handler, and
13369 configurable at run-time (not just at compile time, as in the
13370 "patchy server" releases) [rst]
13372 Changes with Shambhala 0.4.4 30 Jun 1995
13374 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
13375 *) Handle Addtype x/y .z [rst, reported by Cox]
13377 Changes with Shambhala 0.4.3
13379 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
13380 synonymous [rst, terbush]
13382 Changes with Shambhala 0.4.1 28 Jun 1995
13384 *) First-cut virtual host implementation; some refit in the config
13385 reading code, and log management, was necessary to support this [rst]
13386 *) Sub-pool machinery, originally added to avoid excessive storage
13387 allocation on listings of large directories (which turned out to
13388 be the problem that the 0.3 storage accounting was added to
13389 find). Subrequests and mod_dir changed to use subpools. [rst]
13390 *) More memory debugging --- free list consistency checks. [rst]
13391 *) Added err_headers to request_rec, with support elsewhere [rst]
13392 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
13394 Changes with Shambhala 0.3 19 Jun 1995
13396 *) Switch ONE_PROCESS to a runtime command-line option (-X)
13397 *) Don't compile in mod_ai_backcompat by default
13398 *) Switch name of server from Apache to Shambhala in Makefile
13399 *) Add some accounting routines to track memory usage in the pools,
13402 Changes with Shambhala 0.2
13404 *) Set DOCUMENT_ROOT CGI variable
13405 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
13406 *) Add critical section protection to handling of cleanup structures
13408 *) Significant code reorg within the server core to group related
13409 functions together [rst]
13410 *) Correctly handle clients that hang up before sending any request
13412 *) Replace dying child processes. [rst]
13414 Changes with Shambhala 0.1 12 Jun 1995
13416 Major rewrite of the pre-existing "patchy server" codebase, by
13417 Robert Thau (rst). Significant portions of the server code, such
13418 as configuration-file handling and HTTP authentication support,
13419 were ripped out and rewritten from scratch. Code that was not
13420 completely rewritten was significantly altered.
13422 Major changes with this release include:
13424 *) Introduction of the module API; in request handling, the central
13425 machinery just dispatches to various modules, which actually do
13426 most of the work. Configuration handling is similar --- modules
13427 declare their own commands, and the central machinery just
13428 dispatches to them.
13430 API features from shambhala/0.1 were substantially unchanged in
13431 Apache 1.0 and 1.1. (1.0 API features not yet present in this
13432 release, such as wildcard handlers and subpools, were added in
13433 subsequent Shambhala releases, and were also generally rst's
13436 *) This release included the following modules:
13438 mod_access (access control --- allow and deny directives),
13439 mod_alias (Alias and Redirect commands),
13440 mod_auth (straight HTTP authentication, based on flat-files)
13441 mod_auth_dbm (same, with dbm files)
13442 mod_cgi (CGI scripts and, in this release, ScriptAlias)
13443 mod_common_log (CLF access logs; later renamed mod_log_common)
13444 mod_dir (directory indexing)
13445 mod_include (server-side includes)
13446 mod_mime (AddType directives)
13447 mod_negotiation (content negotiation)
13448 mod_userdir (support for users' public_html directories)
13450 It also included a mod_ai_backcompat, which was a private hack
13451 for back-compatibility with rst's own AI-lab servers.
13453 All of these modules were substantially complete, and functional
13454 or nearly so (a few, which implemented features not in use at
13455 Thau's site, required patches of a few lines).
13457 *) sub-request machinery, to allow modules to determine how other
13458 modules would assign MIME types to a given file, or optionally
13459 serve its content (this is heavily used by mod_dir, mod_include
13460 and mod_negotiation).
13462 *) Resource pool system for keeping track of memory allocated and
13463 files opened in service of a particular request. Much of the
13464 code in the modules (when they weren't rewrites) was adjusted to
13465 replace a pervasive convention of using fixed-size buffers on
13466 the stack with an equally pervasive convention of using memory
13467 allocated with palloc().
13469 *) Reorganization of data structures associated with a given
13470 request to eliminate use of global variables and the troublesome
13471 unmunge_name function (used in NCSA and early Apache releases to
13472 attempt to determine the URI which mapped to a given filename
13473 --- a difficult proposition, given that it is easy to produce
13474 setups in which multiple URIs map to the same file).
13476 *) Source files renamed and rearranged
13478 *) Very simple pre-forking behavior --- parent process forked off a
13479 fixed number of children, and then just waited for SIGHUP.
