3 [Remove entries to the current 2.0 section below, when backported]
7 Changes with Apache 2.0.44
9 *) mod_negotiation: Set the appropriate mime response headers
10 (Content-Type, charset, Content-Language and Content-Encoding)
11 for negotated type-map "Body:" responses (such as the error
12 pages.) [André Malo <nd@perlig.de>]
14 *) mod_log_config: Allow '%%' escaping in CustomLog format
15 strings to insert a literal, single '%'.
16 [André Malo <nd@perlig.de>]
18 *) Fix the building of cgi command lines when the query string
19 contains '='. PR 13914 [Ville Skyttä <ville.skytta@iki.fi>,
22 *) Replace APU_HAS_LDAPSSL_CLIENT_INIT with APU_HAS_LDAP_NETSCAPE_SSL
23 as set by apr-util in util_ldap.c. This should allow mod_ldap
24 to work with the Netscape/Mozilla LDAP library. [Øyvin Sømme
25 <somme@oslo.westerngeco.slb.com>, Graham Leggett]
27 *) Reorder the definitions for mod_ldap and mod_auth_ldap within
28 config.m4 to make sure the parent mod_ldap is defined first.
29 This ensures that mod_ldap comes before mod_auth_ldap in the
30 httpd.conf file, which is necessary for mod_auth_ldap to load.
31 PR 14256 [Graham Leggett]
33 *) Fix critical bug in new --enable-v4-mapped configure option
34 implementation which broke IPv4 listening sockets on some
35 systems. [hiroyuki hanai <hanai@imgsrc.co.jp>]
37 *) mod_autoindex: AddDescription directives for directories
38 now work as in Apache 1.3, where no trailing '/' is
39 specified on the directory name. Previously, the trailing
40 '/' *had* to be specified, which was incompatible with
41 Apache 1.3. PR 7990 [Jeff Trawick]
43 *) Fix for PR 14556. The expiry calculations in mod_cache were
44 trying to perform "now + ((date - lastmod) * factor)" where
45 date == lastmod resulting in "now + 0". The code now follows
46 the else path (using the default expiration) if date is
47 equal to lastmod. [rx@armstrike.com (Sergey), Paul J. Reder]
49 *) Use AP_DECLARE in the debug versions of ap_strXXX in case the
50 default calling convention is not the same as the one used by
51 AP_DECLARE. [Juan Rivera <Juan.Rivera@citrix.com>]
53 *) mod_cache: Don't cache response header fields designated
54 as hop-by-hop headers in HTTP/1.1 (RFC 2616 Section 13.5.1).
55 [Estrade Matthieu <estrade-m@ifrance.com>, Brian Pane]
57 *) mod_cgid: Handle environment variables containing newlines.
58 PR 14550 [Piotr Czejkowski <apache@czarny.eu.org>, Jeff
61 *) Move mod_ext_filter out of experimental and into filters.
64 *) Fixed a memory leak in mod_deflate with dynamic content.
65 PR 14321 [Ken Franken <kfranken@decisionmark.com>]
67 *) Add --[enable|disable]-v4-mapped configure option to control
68 whether or not Apache expects to handle IPv4 connections
69 on IPv6 listening sockets. Either setting will work on
70 systems with the IPV6_V6ONLY socket option. --enable-v4-mapped
71 must be used on systems that always allow IPv4 connections on
72 IPv6 listening sockets. PR 14037 (Bugzilla), PR 7492 (Gnats)
75 *) This fixes a problem where the underlying cache code
76 indicated that there was one more element on the cache
77 than there actually was. This happened since element 0
78 exists but is not used. This code allocates the correct
79 number of useable elements and reports the number of
80 actually used elements. The previous code only allowed
81 MCacheMaxObjectCount-1 objects to be stored in the
82 cache. [Paul J. Reder]
84 *) mod_setenvif: Add SERVER_ADDR special keyword to allow
85 envariable setting according to the server IP address
86 which received the request. [Ken Coar]
88 *) mod_cgid: Terminate CGI scripts when the client connection
89 drops. PR 8388 [Jeff Trawick]
91 *) Rearrange OpenSSL engine initialization to support RAND
92 redirection on crypto accelerator.
93 [Frederic DONNAT <frederic.donnat@zencod.com>]
95 *) Always emit Vary header if mod_deflate is involved in the
96 request. [Andre Malo <nd@perlig.de>]
98 *) mod_isapi: Stop unsetting the 'empty' query string result with
99 a NULL argument in ecb->lpszQueryString, eliminating segfaults
100 for some ISAPI modules. PR 14399
101 [Detlev Vendt <detlev.vendt@brillit.de>]
103 *) mod_isapi: Fix an issue where the HSE_REQ_DONE_WITH_SESSION
104 notification is received before the HttpExtensionProc() returns
105 HSE_STATUS_PENDING. This only affected isapi .dll's configured
106 with the ISAPIFakeAsync on directive. PR 11918
107 [John DeSetto <jdesetto@radiantsystems.com>, William Rowe]
109 *) mod_isapi: Fix the issue where all results from mod_isapi would
110 run through the core die handler resulting in invalid responses
111 or access log entries. PR 10216 [William Rowe]
113 *) Improves the user friendliness of the CacheRoot processing
114 over my last pass. This version avoids the pool allocations
115 but doesn't avoid all of the runtime checks. It no longer
116 terminates during post-config processing. An error is logged
117 once per worker, indicating that the CacheRoot needs to be set.
120 *) Fix a bug where we keep files open until the end of a
121 keepalive connection, which can result in:
122 (24)Too many open files: file permissions deny server access
123 especially on threaded servers. [Greg Ames, Jeff Trawick]
125 *) Fix a bug in which mod_proxy sent an invalid Content-Length
126 when a proxied URL was invoked as a server-side include within
127 a page generated in response to a form POST. [Brian Pane]
129 *) Added code to process min and max file size directives and to
130 init the expirychk flag in mod_disk_cache. Added a clarifying
131 comment to cache_util. [Paul J. Reder]
133 *) The value emitted by ServerSignature now mimics the Server HTTP
134 header as controlled by ServerTokens. [Francis Daly <deva@daoine.org>]
136 *) Gracefully handly retry situations in the SSL input filter,
137 by following the SSL libraries' retry semantics.
140 *) Terminate CGI scripts when the client connection drops. This
141 fix only applies to some normal paths in mod_cgi. mod_cgid
142 is still busted. PR 8388 [Jeff Trawick]
144 *) Fix a bug where 416 "Range not satisfiable" was being
145 returned for content that should have been redirected.
148 *) Fix memory leak in mod_ssl from internal SSL library allocations
149 within SSL_get_peer_certificate and X509_get_pubkey.
150 [Zvi Har'El <rl@math.technion.ac.il>
151 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>].
153 *) mod_ssl uses free() inappropriately in several places, to free
154 memory which has been previously allocated inside OpenSSL.
155 Such memory should be freed with OPENSSL_free(), not with free().
156 [Nadav Har'El <nyh@math.technion.ac.il>,
157 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>].
159 *) Emit a message to the error log when we return 404 because
160 the URI contained '%2f'. (This was previously nastily silent
161 and difficult to debug.) [Ken Coar]
163 *) Fix streaming output from an nph- CGI script. CGI:IRC now
164 works. PR 8482 [Jeff Trawick]
166 *) More accurate logging of bytes sent in mod_logio when
167 the client terminates the connection before the response
168 is completely sent [Bojan Smojver <bojan@rexursive.com>]
170 *) Fix some problems in the perchild MPM.
171 [Jonas Eriksson <jonas@webkonsulterna.com>]
173 *) Change the CacheRoot processing to check for a required
174 value at config time. This saves a lot of wasted processing
175 if the mod_disk_cache module is loaded but no CacheRoot
176 was provided. This fix also adds code to log an error
177 and avoid useless pallocs and procesing when the computed
178 cache file name cannot be opened. This also updates the
179 docs accordingly. [Paul J. Reder]
181 *) Introduce the EnableSendfile directive, allowing users of NFS
182 shares to disable sendfile mechanics when they either fail
183 outright or provide intermitantly corrupted data. PR
186 *) Resolve the error "An operation was attempted on something
187 that is not a socket. : winnt_accept: AcceptEx failed.
188 Attempting to recover." for users of various firewall and
189 anti-virus software on Windows. PR 8325 [William Rowe]
191 *) Add the ProxyBadHeader directive, which gives the admin some
192 control on how mod_proxy should handle bogus HTTP headers from
193 proxied servers. This allows 2.0 to "emulate" 1.3's behavior if
194 desired. [Jim Jagielski]
196 *) Change the LDAP modules to export their symbols correctly
197 during a Windows build. Add dsp files for Windows. Update
198 README.ldap file for Windows build instructions.
199 [Andre Schild <A.Schild@aarboard.ch>]
201 *) Performance improvements for the code that generates HTTP
202 response headers [Brian Pane]
204 *) Add -S as a synonym for -t -DDUMP_VHOSTS.
205 [Thom May <thom@planetarytramp.net>]
207 *) Fix a bug with dbm rewrite maps which caused the wrong value to
208 be used when the key was not found in the dbm. PR 13204
211 *) Fix a problem with streaming script output and mod_cgid.
214 *) Add ap_register_provider/ap_lookup_provider API.
215 [John K. Sterling <john@sterls.com>, Justin Erenkrantz]
217 *) Rewrite of aaa modules to an authn/authz model.
218 [Dirk-Willem van Gulik, Justin Erenkrantz]
220 Changes with Apache 2.0.43
222 *) SECURITY: [CAN-2002-0840] HTML-escape the address produced by
223 ap_server_signature() against this cross-site scripting
224 vulnerability exposed by the directive 'UseCanonicalName Off'.
225 Also HTML-escape the SERVER_NAME environment variable for CGI
226 and SSI requests. It's safe to escape as only the '<', '>',
227 and '&' characters are affected, which won't appear in a valid
228 hostname. Reported by Matthew Murphy <mattmurphy@kc.rr.com>.
231 *) Fix a core dump in mod_cache when it attemtped to store uncopyable
232 buckets. This happened, for instance, when a file to be cached
233 contained SSI tags to execute a CGI script (passed as a pipe
234 bucket). [Paul J. Reder]
236 *) Ensure that output already available is flushed to the network
237 when the content-length filter realizes that no new output will
238 be available for a while. This helps some streaming CGIs as
239 well as some other dynamically-generated content. [Jeff Trawick]
241 *) Fix a mutex problem in mod_ssl session cache support which
242 could lead to an infinite loop. PR 12705
243 [amund.elstad@ergo.no (Amund Elstad), Jeff Trawick]
245 *) SECURITY: CAN-2002-1156 (cve.mitre.org)
246 Fix the exposure of CGI source when a POST request is sent to
247 a location where both DAV and CGI are enabled. [Ryan Bloom]
249 *) Allow the UserDir directive to accept a list of directories.
250 This matches what Apache 1.3 does. Also add documentation for
251 this feature. [Jay Ball <jay@veggiespam.com>]
253 *) New Module: mod_logio. adds the ability to log bytes sent and
254 received. [Bojan Smojver <bojan@rexursive.com>]
256 *) SuExec needs to use the same default directory as the rest of
257 server, namely /usr/local/apache2.
258 [SangBeom han <sbhan@os.korea.ac.kr>]
260 *) Get mod_auth_ldap to retry connections on LDAP_SERVER_DOWN.
261 [Thomas Bennett <thomas.bennett@eds.com>, Graham Leggett]
263 *) Make sure the contents of the WWW-Authenticate header is
264 passed on a 4xx error by proxy. Previously all headers
265 were dropped, resulting in the browser being unable to
266 authenticate. [Dr Richard Reiner <rreiner@fscinternet.com>,
267 Richard Danielli <rdanielli@fscinternet.com>, Graham Wiseman
268 <gwiseman@fscinternet.com>, David Henderson
269 <dhenderson@fscinternet.com>]
271 *) Make mod_cache's CacheMaxStreamingBuffer directive work
272 properly for virtual hosts that override server-wide mod_cache
273 setttings. [Matthieu Estrade <estrade-m@ifrance.com>]
275 *) Add -p option to apxs to allow programs to be compiled with apxs.
278 Changes with Apache 2.0.42
280 *) mod_dav: Check for versioning hooks before using them.
283 Changes with Apache 2.0.41
285 *) The protocol version (eg: HTTP/1.1) in the request line parsing
286 is now case insensitive. [Jim Jagielski]
288 *) Allow AddOutputFilterByType to add multiple filters per directive.
291 *) Remove warnings with Sun's Forte compiler. [Justin Erenkrantz]
293 *) Fixed mod_disk_cache's generation of 304s
294 [Kris Verbeeck <Kris.Verbeeck@ubizen.com>]
296 *) Add support for using fnmatch patterns in the final path
297 segment of an Include statement (eg.. include /foo/bar/*.conf).
298 and remove the noise on stderr during config dir processing.
299 [Joe Orton <jorton@redhat.com>]
301 *) mod_cache: cache_storage.c. Add the hostname and any request
302 args to the key generated for caching. This provides a unique
303 key for each virtual host and for each request with unique
304 args. [Paul J. Reder, args code provided by Kris Verbeeck]
306 *) mod_cache: Do not cache responses to GET requests with query
307 URLs if the origin server does not explicitly provide an
308 Expires header on the response (RFC 2616 Section 13.9)
309 [Kris Verbeeck krisv@be.ubizen.com]
311 *) Fix memory leak in core_output_filter. [Justin Erenkrantz]
313 *) Update OpenSSL detection to work on Darwin.
314 [Sander Temme <sctemme@covalent.net>]
316 *) Update the xslt and css to give the documentation a more
318 [André Malo <nd@perlig.de>, Gernot Winkler <greh@o3media.de>]
320 *) Fix some bucket memory leaks in the chunking code
321 [Joe Schaefer <joe+apache@sunstarsys.com>]
323 *) Add ModMimeUsePathInfo directive. [Justin Erenkrantz]
325 *) mod_cache: added support for caching streamed responses (proxy,
326 CGI, etc) with optional CacheMaxStreamingBuffer setting [Brian Pane]
328 *) Add image/x-icon to httpd.conf PR 10993.
329 [Ian Holsman, Peter Bieringer <pb@bieringer.de>]
331 *) Fix FileETags none operation. PR 12207.
332 [Justin Erenkrantz, Andrew Ho <andrew@tellme.com>]
334 *) Restored the experimental leader/followers MPM to working
335 condition and converted its thread synchronization from
336 mutexes to atomic CAS. [Brian Pane]
338 *) Fix Logic on non-html file removal in mod_deflate
339 [Kris Verbeeck <Kris.Verbeeck@ubizen.com>]
341 *) Fix "ab -g"'s truncated year: the last digit was cut off.
342 [Leon Brocard <acme@astray.com>]
344 *) mod_rewrite can now sets cookies in err_headers, uses the correct
345 expiry date, and can now set the path as well
346 PR 12132,12181,12172.
347 [Ian Holsman / Rob Cromwell <apachechangelog@robcromwell.com>]
349 *) The content-length filter no longer tries to buffer up
350 the entire output of a long-running request before sending
351 anything to the client. [Brian Pane]
353 *) Win32: Lower the default stack size from 1MB to 256K. This will
354 allow around 8000 threads to be started per child process.
355 'EDITBIN /STACK:size apache.exe' can be used to change this
356 value directly in the apache.exe executable.
359 *) Win32: Implement ThreadLimit directive in the Windows MPM.
362 *) Remove CacheOn config directive since it is set but never checked.
363 No sense wasting cycles on unused code. Besides, the only truly
364 bug free code is deleted code. :) [Paul J. Reder]
366 *) BufferLogs are now run-time enabled, and the log_config now has 2 new
367 callbacks to allow a 3rd party module to actually do the writing of the
368 log file [Ian Holsman]
370 *) Correct ISAPIReadAheadBuffer to default to 49152, per mod_isapi docs.
371 [André Malo, Astrid Keßler <kess@kess-net.de>]
373 *) Fix Segfault in mod_cache. [Kris Verbeeck <Kris.Verbeeck@ubizen.com>]
375 *) Fix a null pointer dereference in the merge_env_dir_configs
376 function of the mod_env module. PR 11791
379 *) New option to ServerTokens 'maj[or]'. Only show the major version
380 Also Surfaced this directive in the standard config (default FULL)
383 *) Change mod_rewrite to use apr-util's dbm support for dbm rewrite
384 maps. The dbm type (e.g., ndbm, gdbm) can be specified on the
385 RewriteMap directive. PR 10644 [Jeff Trawick]
387 *) Fixed mod_rewrite's RewriteMap prg: support so that request/response
388 pairs will no longer get out of sync with each other. PR 9534
391 *) Fixes required to get quoted and escaped command args working in
392 mod_ext_filter. PR 11793 [Paul J. Reder]
394 *) mod-proxy: handle proxied responses with no status lines
395 [JD Silvester <jsilves@uwo.ca>, Brett Huttley <brett@huttley.net>]
397 *) Fix bug where environment or command line arguments containing
398 non-ASCII-7 characters would cause the Win32 child process creation
399 to fail. PR 11854 [William Rowe]
401 *) Bug #11213.. make module loading error messages more informative
402 [Ian Darwin <Ian779@darwinsys.com>]
404 *) thread safety & proxy-ftp [Alexey Panchenko alexey@liwest.ru, Ian Holsman]
406 *) mod_disk_cache works much better. This module should still
407 be considered experimental. [Eric Prud'hommeaux]
409 *) Performance improvement for keepalive requests: when setting
410 aside a small file for potential concatenation with the next
411 response on the connection, set aside the file descriptor rather
412 than copying the file into the heap. [Brian Pane]
414 Changes with Apache 2.0.40
416 *) SECURITY: [CAN-2002-0661] Close a very significant security hole that
417 applies only to the Win32, OS2 and Netware platforms. Unix was not
418 affected, Cygwin may be affected. Certain URIs will bypass security
419 and allow users to invoke or access any file depending on the system
420 configuration. Without upgrading, a single .conf change will close
421 the vulnerability. Add the following directive in the global server
422 httpd.conf context before any other Alias or Redirect directives;
423 RedirectMatch 400 "\\\.\."
424 Reported by Auriemma Luigi <bugtest@sitoverde.com>.
427 *) SECURITY: Close a path-revealing exposure in multiview type
428 map negotiation (such as the default error documents) where the
429 module would report the full path of the typemapped .var file when
430 multiple documents or no documents could be served based on the mime
431 negotiation. Reported by Auriemma Luigi <bugtest@sitoverde.com>.
432 [CAN-2002-0654] [William Rowe]
434 *) SECURITY: Close a path-revealing exposure in cgi/cgid when we
435 fail to invoke a script. The modules would report "couldn't create
436 child process /path-to-script/script.pl" revealing the full path
437 of the script. Reported by Jim Race <jrace@qualys.com>.
438 [CAN-2002-0654] [Bill Stoddard]
440 *) Set aside the apr-iconv and apr_xlate() features for the Win32
441 build of 2.0.40 so development can be completed. A patch, from
442 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
443 will be available for those that wish to work with apr-iconv.
446 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
447 chain. [Peter Van Biesen <peter.vanbiesen@vlafo.be>]
449 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
450 set to 1, so we can exclude things from the general case with
451 browsermatch. [Ian Holsman, Andre Schild <A.Schild@aarboard.ch>]
453 *) Accept multiple leading /'s for requests within the DocumentRoot.
454 PR 10946 [William Rowe, David Shane Holden <dpejesh@yahoo.com>]
456 *) Solved the reports of .pdf byterange failures on Win32 alone.
457 APR's sendfile for the win32 platform collapses header and trailer
458 buffers into a single buffer. However, we destroyed the pointers
459 to the header buffer if a trailer buffer was present. PR 10781
462 *) mod_ext_filter: Add the ability to enable or disable a filter via
463 an environment variable. Add the ability to register a filter of
464 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
466 *) Restore the ability to specify host names on Listen directives.
467 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh@yahoo.com>]
469 *) When deciding on the default address family for listening sockets,
470 make sure we can actually bind to an AF_INET6 socket before
471 deciding that we should default to AF_INET6. This fixes a startup
472 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
474 *) Replace usage of atol() to parse strings when we might want a
475 larger-than-long value with apr_atoll(), which returns long long.
476 This allows HTTPD to deal with larger files correctly.
477 [Shantonu Sen <ssen@apple.com>]
479 *) mod_ext_filter: Ignore any content-type parameters when checking if
480 the response should be filtered. Previously, "intype=text/html"
481 wouldn't match something like "text/html;charset=8859_1".
484 *) mod_ext_filter: Set up environment variables for external programs.
485 [Craig Sebenik <craig@netapp.com>]
487 *) Modified the HTTP_IN filter to immediately append the EOS (end of
488 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
489 the caller to determine that no content remains without prefetching
490 additional POST body. [William Rowe]
492 *) Get proxy ftp to work over IPv6. [Shoichi Sakane <sakane@kame.net>]
494 *) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml@suse.de>]
496 *) Update SuSE layout. [Peter Poeml <poeml@suse.de>]
498 *) Changes to the internationalized error documents:
499 Comment them out in the default config file to make the default
500 install as simple as possible; Correct the english 500 error to
501 be more understandable; Add a Swedish translation.
502 [Thomas Sjogren <thomas@northernsecurity.net>,
503 Erik Abele <erik@codefaktor.de>, Rich Bowen, Joshua Slive]
505 *) Increase the limit on file descriptors per process in apachectl.
508 *) Fix a dependency error when building ApacheMonitor, so that Win32
509 and MSVC now trust that the project is current (when it is).
510 [James Cox <imajes@php.net>]
512 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
513 [Arthur P. Smith <apsmith@aps.org>, Jeff Trawick]
515 *) APR-Util Renames pending have been completed [Thom May]
517 *) Performance improvements for the code that reads request
518 headers (ap_rgetline_core() and related functions) [Brian Pane]
520 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
521 to configure the maximum amount of memory the allocators will
522 hold on to for reuse. Anything over the MaxMemFree threshold
523 will be free()d. This directive is useful when uncommon large
524 peaks occur in memory usage. It should _not_ be used to mask
525 defective modules' memory use. [Sander Striker]
527 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
528 scripts would not result in a truncated response.
529 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
531 *) Add a filter_init parameter to the filter registration functions
532 so that a filter can execute arbitrary code before the handlers
533 are invoked. This resolves a problem where mod_include requests
534 would incorrectly return a 304. [Justin Erenkrantz]
536 *) Fix a long-standing bug in 2.0, CGI scripts were being called
537 with relative paths instead of absolute paths. Apache 1.3 used
538 absolute paths for everything except for SuExec, this brings back
539 that standard. [Ryan Bloom]
541 *) Fix infinite loop due to two HTTP_IN filters being present for
542 internally redirected requests. PR 10146. [Justin Erenkrantz]
544 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
547 *) Fix mod_ext_filter to look in the main server for filter definitions
548 when running in a vhost if the filter definition is not found in
549 the vhost. PR 10147 [Jeff Trawick]
551 *) Support WinNT CGI invocation through ScriptInterpreterSource
552 'registry' for script interpreter paths and names with non-ascii
553 characters in the executable filepath. [William Rowe]
555 *) Support the -w flag on to keep the Win32 console open on error.
558 *) Normalize the hostname value in the request_rec to all-lowercase
559 [Perry Harrington <pedward@webcom.com>]
561 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
562 extended characters (non US-ASCII) in non-utf8 format. This brings
563 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
564 to the cgi application itself. [William Rowe]
566 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
567 modules to bring them up to the current apr/apr-util APIs.
570 *) Fix segfault in mod_mem_cache most frequently observed when
571 serving the same file to multiple clients on an MP machine.
574 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
575 [Brian Degenhardt <bmd@mp3.com>, Ian Holsman]
577 *) Fix perchild to work with apachectl by adding -k support to perchild.
578 PR 10074 [Jeff Trawick]
580 *) Fix a silly htpasswd.c logic error that incorrectly reported that
581 both -c and -n had been used. PR 9989 [Cliff Woolley]
583 *) Fixed a mod_include error case in which no HTTP response was sent
584 to the client if an shtml document contained an unterminated SSI
585 directive [Brian Pane]
587 *) Improve ap_get_client_block implementation by using APR-util brigade
588 helper functions and relying on current filter assumptions.
591 Changes with Apache 2.0.39
593 *) Fixed a build problem in htpasswd.c on Win32.
594 [Guenter Knauf <eflash@gmx.net>, Cliff Woolley]
596 Changes with Apache 2.0.38
598 *) Rewrite htpasswd to use APR. The removes the annoying warning about
599 tmpnam being unsafe. [Ryan Bloom]
601 *) We must set the MIME-type for .shtml files to text/html if we want them
602 to be parsed for SSI tags. Add the config for that to the default
603 config file so that it is easier to enable .shtml parsing.
604 [Dave Dyer <ddyer@real-me.net>]
606 *) Fixed a problem with 'make install' on ReliantUnix.
607 [Jean-frederic Clere <jfrederic.clere@fujitsu-siemens.com>]
609 *) Make the default_handler catch all requests that aren't served by
610 another handler. This also gets us to return a 404 if a directory
611 is requested, there is no DirectoryIndex, and mod_autoindex isn't
612 loaded. [Justin Erenkrantz]
614 *) Fixed the handling of nested if-statements in shtml files.
617 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
618 into a directory different from the one that was configured. This
619 also mirrors the root= feature from 1.3. We cannot use prefix=,
620 because both APR and APR-util resolve their installation paths at
621 configuration time. This means that there is no variable prefix
622 to replace. [Andreas Hasenack <andreas@netbank.com.br>]
624 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
625 These levels of AIX don't have a thundering herd problem with
626 accept(). [Jeff Trawick]
628 *) prefork MPM: Ignore mutex errors during graceful restart. For
629 certain types of mutexes (particularly SysV semaphores), we
630 should expect to occasionally fail to obtain or release the
631 mutex during restart processing. [Jeff Trawick]
633 *) Fix install-bindist.sh so that it finds any perl instead of just
634 early perl 5.x versions. This is consistent with a build/install
635 from source, and it allows the perl scripts installed by a bindist
636 to work on systems with perl 5.6. [Jeff Trawick]
638 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
639 Tru64 (and probably some other platforms). [Jeff Trawick]
641 *) Allow CGI scripts to return their Content-Length. This also fixes a
642 hang on HEAD requests seen on certain platforms (such as FreeBSD).
645 *) Added log rotation based on file size to the RotateLog support
646 utility. [Brad Nicholes]
648 *) Fix some casting in mod_rewrite which broke random maps.
649 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
651 Changes with Apache 2.0.37
653 *) allow POST method over SSL when per-directory client cert
654 authentication is used with 'SSLOptions +OptRenegotiate' enabled
655 and a client cert was found in the ssl session cache.
657 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
658 session cache when there is no cert chain in the cache. prior to
659 the fix this situation would result in a FORBIDDEN response and
660 error message "Cannot find peer certificate chain"
663 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
664 one was already sent. PR 9644 [Jeff Trawick]

667 file. PR 9729 [Matthew Brecknell <mbrecknell@orchestream.com>]

672 Solves the case of ServerRoot /foo paths where /foo was not
673 on the same drive as /winnt/system32. [William Rowe]

676 match how 1.3 does it. [Jim Jagielski]
678 *) Implement a fixed size memory cache using a priority queue
681 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
682 querying certain other variables from config_vars.mk. PR 9316
685 *) Added the "detached" attribute to the cgi_exec_info_t internals
686 so that Win32 and Netware won't create a new window or console
687 for each CGI invoked. PR 8387
688 [Brad Nicholes, William Rowe]
690 *) Consolidated the command line parameters and attributes that are
691 manipulated by the optional function ap_cgi_build_command() in
692 mod_cgi into a single structure.
695 *) Get rid of uninitialized value errors with "apxs -q" on certain
696 variables. [Stas Bekman <stas@stason.org>]
698 *) Fix apxs to allow it to work when the build directory is somewhere
699 besides server-root/build. PR 8453
700 [Jeff Trawick and a host of others]
702 *) Allow ap_discard_request_body to be called multiple times in the
703 same request. Essentially, ap_http_filter keeps track of whether
704 it has sent an EOS bucket up the stack, if so, it will only ever
705 send an EOS bucket for this request.
706 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
708 *) Remove all special mod_ssl URIs. This also fixes the bug where
709 redirecting (.*) will allow an SSL protected page to be viewed
710 without SSL. [Ryan Bloom]
712 *) Fix the binary build install script so that the build logic
713 created by "apxs -g" will work when the user has a binary
714 build. [Jeff Trawick]
716 *) Allow instdso.sh to work with full paths to the shared module.
719 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
720 in module for NetWare [Brad Nicholes]
722 *) Changed cgi and piped log behavior to accept 65536 characters
723 on Win32 (matching Linux) before deadlocking between outputing
724 client stdin, slurping the output from stdout and then the stderr
725 stream. PR 8179 [William Rowe]
727 *) Fixed Win32 wintty.exe support to assure the window title is valid.
728 Elimiates possible gpfault or garbage title without the -t option.
731 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
732 brigades and input filters. [Justin Erenkrantz]
734 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
735 body. [Justin Erenkrantz]
737 *) NetWare: Piping log entries through RotateLogs using the
738 CustomLogs directive is finally supported now that we have

761 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
762 stripping the content_type from cached responses.
765 *) apachectl passes through any httpd options. Note: apachectl
766 should be used in preference to httpd since it ensures that any
767 appropriate environment variables have been set up.

814 of Apache. [Jeff Trawick]
816 *) Removed documentation references to the no-longer-supported

818 certificates, if truly desired, can be generated using openssl
819 commands. PR 8724. [Cliff Woolley]
821 *) Remove SSLLog and SSLLogLevel directives in favor of having
822 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
824 *) OS/390: LIBPATH no longer has to be manually uncommented in
825 envvars to get apachectl to set up httpd properly. [Jeff Trawick]
827 *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
828 may now be specified to the <File/Directory > container, rather
829 than by vhost. [William Rowe]
831 *) mod_isapi: Experimental support for faux async support for ISAPI
832 modules. [William Rowe]
834 *) mod_isapi: Major refactoring of the code to rely on apr internals
835 rather than MS APIs (using our own mod_isapi.h headers for ISAPI
836 symbol definitions.) [William Rowe]
838 *) mod_isapi: Fixed the return string length from GetServerVariable
839 callback, it was not including the trailing null in the consumed

909 This left the user in an ambiguous state. PR 8320 [Paul J. Reder]
911 *) Close sockets on worker MPM when doing a graceless restart.
914 *) Reverted a minor optimization in mod_ssl.c that used the vhost ID
915 as the session id context rather that a MD5 hash of that vhost ID,
916 because it caused very long vhost id's to be unusable with mod_ssl.
917 PR 8572. [Cliff Woolley]
919 *) Fix the link to the description of the CoredumpDirectory
920 directive in the server-wide document. PR 8643. [Jeff Trawick]
922 *) Fixed SHMCB session caching. [Aaron Bannert, Cliff Woolley]
924 *) Synced with remaining changes from mod_ssl 2.8.8-1.3.24:
925 - Avoid SIGBUS on sparc machines with SHMCB session caches
926 - Allow whitespace between the pipe and the name of the
927 program in SSLLog "| /path/to/program". [Cliff Woolley]
929 *) Introduce mod_ext_filter and mod_deflate experimental modules
930 to the Win32 build (zlib sources must be in srclib\zlib.)
933 *) Changes to the worker MPM's queue management and thread
934 synchronization code to reduce mutex contention [Brian Pane]
936 *) Don't install *.in configuration files since we already install
937 *-std.conf files. [Aaron Bannert]
939 *) Many improvements to the threadpool MPM. [Aaron Bannert]
941 *) Fix subreqs that are promoted via fast_redirect from having invalid
942 frec->r structures. This would cause subtle errors later on in
943 request processing such as seen in PR 7966. [Justin Erenkrantz]
945 *) More efficient pool recycling logic for the worker MPM [Brian Pane]
947 *) Modify the worker MPM to not accept() new connections until
948 there is an available worker thread. This prevents queued
949 connections from starving for processing time while long-running
950 connections were hogging all the available threads. [Aaron Bannert]

995 *) Fix AcceptPathInfo. PR 8234 [Cliff Woolley]
997 *) SECURITY: Added the APLOG_TOCLIENT flag to ap_log_rerror() to
998 explicitly tell the server that warning messages should be sent
999 to the client in addition to being recorded in the error log.
1000 Prior to this change, ap_log_rerror() always sent warning
1001 messages to the client. In one case, a faulty CGI script caused
1002 the server to send a warning message to the client that contained
1003 the full path to the CGI script. This could be considered a
1004 minor security exposure. [Bill Stoddard]
1006 *) mod_autoindex output when SuppressRules was specified would
1007 omit the first carriage return so the first item in the list

1009 underneath them. PR 8016 [David Shane Holden <dpejesh@yahoo.com>]
1011 *) Moved the call to apr_mmap_dup outside the error branch so
1012 that it would actually get called. This fixes a core dump
1013 at init everytime you use the MMapFile directive. PR 8314
1016 *) Trigger an error when a LoadModule directive attempts to
1017 load a module which is built-in. This is a common error when
1018 switching from a DSO build to a static build. [Jeff Trawick]
1020 *) Change instdso.sh to use libtool --install everywhere and then
1021 clean up some stray files and symlinks that libtool leaves around
1022 on some platforms. This gets subversion building properly since
1023 it needed a re-link to be performed by libtool at install time,
1024 and the old instdso.sh logic to simply cp the DSO didn't handle
1025 that requirement. [Sander Striker]

1036 *) Fix segfault in mod_mem_cache when garabge collecting an expired
1037 cache entry. [Bill Stoddard]
1039 *) Introduced -E startup_logfile_name option to httpd to allow admins
1040 to begin logging errors immediately. This provides Win32 users
1041 an alternative to sending startup errors to the event viewer, and
1042 allows other daemon tool authors an alternative to logging to stderr.

1132 cause the Apache parent process to run in the foreground (similar to
1133 -DNO_DETACH except that it doesn't switch session ids).
1136 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
1137 for those platforms that support it. If using the default
1138 implementation, this is between pthread and sysvsem in priority.
1139 This implies it's the new default for Darwin. [Jim Jagielski]

1164 *) Allow all Perchild directives to accept either numerical UID/GID
1165 or logical user/group names. [Scott Lamb <slamb@slamb.org>]
1167 *) Make Perchild compile cleanly and serve pages again. [Ryan Bloom]
1169 *) implement ssl proxy to support ProxyPass / https:// and the
1170 SSLProxy* directives [Doug MacEachern]
1172 *) Update mod_cgid to not do single-byte socket reads for CGI headers
1175 *) Made AB's use of the Host: header rfc2616 compliant
1176 by Taisuke Yamada <tai@iij.ad.jp> [Dirk-Willem van Gulik].
1178 *) The old, legacy (and unused) code in which the scoreboard was totally
1179 and completely contained in a file (SCOREBOARD_FILE) has been
1180 removed. This does not affect scoreboards which are *mapped* to
1181 files using named-shared-memory. [Jim Jagielski]
1183 *) Change bucket brigades API to allow a "bucket allocator" to be
1184 passed in at certain points. This allows us to implement freelists
1185 so that we can stop using malloc/free so frequently.
1186 [Cliff Woolley, Brian Pane]
1188 *) Add support for macro expansion within the variable names in
1189 <!--#echo--> and <!--#set--> directives [Brian Pane]
1191 *) Fix some mod_include segfaults [Cliff Woolley, Brian Pane, Brad Nicholes]
1193 *) Update the "RedHat" Layout to match Red Hat Linux version 7. PR BZ-7422
1196 *) add compat layer to support RSA SSLC 1.x and 2.x in mod_ssl
1197 [Jon Travis, John Barbee, William Rowe, Ryan Bloom, Doug MacEachern]
1199 *) Add a new parameter to the quick_handler hook to instruct
1200 quick handlers to optionally do a lookup rather than actually
1201 serve content. This is the first of several changes required fix
1202 several problems with how quick handlers work with subrequests.
1205 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]
1207 *) [APR-related] The ordering of the default accept mutex method has
1208 been changed to better match what's done in Apache 1.3. The ordering
1209 is now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
1212 *) Ensure that the build/ directory is created when using VPATH.
1215 *) Add some popular types to the mime magic file. PR 7730.
1216 [Linus Walleij <triad@df.lth.se>, Justin Erenkrantz]
1218 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
1220 *) When a proxied site was being served, Apache was replacing
1221 the original site Server header with it's own, which is not
1222 allowed by RFC2616. Fixed. [Graham Leggett]
1224 *) Fix a mod_cgid problem that left daemon processes stranded
1225 in some server restart scenarios. [Jeff Trawick]
1227 *) Added exp_foo and rel_foo variables to config_vars.mk for
1228 all Apache and Autoconf path variables (like --sysconfdir,
1229 --sbindir, etc). exp_foo is the "expanded" version, which means
1230 that all internal variable references have been interpolated.
1231 rel_foo is the same as $exp_foo, only relative to $prefix if they
1232 share a common path. [Aaron Bannert]
1234 *) Fix some restart/terminate problems in the worker MPM. Don't
1235 drop connections during graceful restart. [Jeff Trawick]
1237 *) Change the header merging behaviour in proxy, as some headers
1238 (like Set-Cookie) cannot be unmerged due to stray commas in
1239 dates. [Graham Leggett]
1241 *) Be more vocal about what AcceptMutex values we allow, to make
1242 us closer to how 1.3 does it. [Jim Jagielski]
1244 *) Get nph- CGI scripts working again. PRs 8902, 8907, 9983
1247 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
1249 *) Add accessor function to set r->content_type. From now on,
1250 ap_rset_content_type() should be used to set r->content_type.
1251 This change is required to properly implement the
1252 AddOutputFilterByType configuration directive.
1253 [Bill Stoddard, Sander Striker, Ryan Bloom]
1255 *) Add new M_FOO symbols for the WebDAV/DeltaV methods specified by
1256 RFC 3253. Improved the method name/number mapping functions.
1259 *) remove sock_enable_linger from connection.c [Ian Holsman]
1261 *) Fix for virtual host processing where the requested hostname
1262 has a '.' at the end (PR 9187) [Ryan Cruse <ryan@estara.com>]
1264 *) mod_dav's APIs for REPORT response handling was changed so that
1265 providers can generate the content directly into the output filter
1266 stack, rather than buffering the response into memory. [Greg Stein]
1268 *) Fix a hang condition with graceful restart and prefork MPM
1269 in the situation where MaxClients is very high but
1270 much fewer servers are actually started at the time of the
1271 restart. [Jeff Trawick]
1273 *) Small performance fixes for mod_include [Brian Pane]
1275 *) Performance improvement for the error logger [Brian Pane]
1277 *) Change configure so that Solaris 8 and above have
1278 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
1279 according to sun people solaris 8+ doesn't have a thundering
1280 herd problem [Ian Holsman]
1282 *) Allow URIs specifying CGI scripts to include '/' at the end
1283 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
1284 which ignore '/' at the end of the names of non-directories).
1285 PR 10138 [Jeff Trawick]
1287 *) implement SSLSessionCache shmht and shmcb based on apr_rmm and
1288 apr_shm. [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1290 *) Fix apxs -g handling. Move config_vars.mk from the top build
1291 directory to the build directory. PR 10163 [Jeff Trawick]
1293 *) Fix some mod_include problems which broke evaluation of some
1294 expressions. PR 10108 [Jeff Trawick]
1296 *) Fix the calculation of request time in mod_status. [Stas Bekman]
1298 *) Fix the calculation of thread_num in the worker score structure.
1301 *) Use apr_atomic operations in managing the mod_mem_cache
1302 cache_objects for SMP scalability. (see USE_ATOMICS
1303 preprocessor directive in mod_file_cache)
1306 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
1307 preprocessor directive in mod_file_cache)
1310 *) Implement prototype mod_disk_cache for use with mod_cache.
1313 *) Add a missing manualdir entry in the Debian config.layout.
1314 [Thom May <thom@planetarytramp.net>]
1316 *) Stop installing libtool for APR and tell APR where it should place
1317 its copy of libtool (via our installbuildpath layout variable).
1320 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
1321 when reading from a remote HTTP server in proxy. [Graham Leggett]
1323 *) Modify receive/send loop in proxy_http and proxy_ftp so that
1324 should it be necessary, the remote server socket is closed before
1325 transmitting the last buffer (set by ProxyIOBufferSize) to the
1326 client. This prevents the backend server from being forced to hang
1327 around while the last few bytes are transmitted to a slow client.
1328 Fix the case where no error checking was performed on the final
1329 brigade in the loop. [Graham Leggett]
1331 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
1332 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
1333 hours. [Graham Leggett, Bill Stoddard]
1335 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
1336 for a undefined variable. [Ian Holsman]
1338 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
1339 when we can't get a socket in the specified address family. We may
1340 have gotten back an IPv6 address first and yet our system is not
1341 configured to allow IPv6 sockets. [Jeff Trawick]
1343 *) Be more careful about recursively removing CVS directories. Make
1344 sure that we aren't cd'ing to their home directory first. PR: 9993
1345 [Aaron Bannert, James LewisMoss <dres@lewismoss.net>]
1347 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
1348 [Dirk-Jan Faber <dirk-jan@selwerd.nl>, Aaron Bannert,
1349 Thom May <thom@planetarytramp.net>]
1351 *) Rename the filter ordering priorities. The recent filtering fixes
1352 have showcased problems with their usage. Therefore, we need to
1353 rename them to increase the clarity. (CONTENT->RESOURCE,
1354 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
1356 Changes with Apache 2.0.33
1358 *) Fix a problem in the new --enable-layout functionality where
1359 it wouldn't allow overrides from variables like --prefix,
1360 --bindir, etc. [Thom May <thom@planetarytramp.net>]
1362 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
1363 no longer hangs around waiting for the socket to close before
1364 returning exhaustive data. [Aaron Bannert]
1366 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
1367 [Thom May <thom@planetarytramp.net>]
1369 *) Change mod_ssl to always do a full startup/teardown on restarts.
1370 this allows mod_ssl to be added to a server that is already
1371 running and makes it possible to add/change certs/keys after the
1372 server has been started. [Doug MacEachern]
1374 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
1375 This pipe must be a bidirectional 'console' style relay, which
1376 mod_ssl prints all prompts to the pipe's stdin, and reads the
1377 passphrases from the pipe's stdout. [William Rowe]
1379 *) Fix bug where --sysconfdir and --localstatedir were being
1380 ignored. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
1383 *) Fix --enable-layout to work again. Caution: When specifying
1384 --enable-layout, common arguments like --prefix, --exec-prefix,
1385 etc. will be ignored and the settings from the layout will be
1386 used instead. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
1389 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
1390 regex pattern matching for the determination of which requests
1391 to use the remote proxy for. [Jim Jagielski]
1393 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
1395 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
1396 cruft in piped logs and rewritemap child processes.
1399 *) All instances of apr_lock_t have been removed and converted
1400 to one of the following new lock APIs: apr_thread_mutex.h,
1401 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
1402 use the apr_lock.h API, as the old API will soon be deprecated.
1405 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
1406 [Ralf S. Engelschall, Cliff Woolley]
1408 *) mod-include: make it handle flush'es and fix the 'false-alarm'
1409 [Justin Erenkrantz, Brian Pane, Ian Holsman]
1411 *) ap_get_*_filter_handle() functions to allow 3rd party modules
1412 to lookup filter handles so they can bypass the filter name
1413 lookup when adding filters to a request (via ap_add_*_filter_handle())
1414 [Ryan Morgan <rmorgan@covalent.net>]
1416 *) Fix for multiple file buckets on Win32, where the first file
1417 bucket would cause the immediate closure of the socket on any
1418 non-keepalive requests. [Ryan Morgan <rmorgan@covalent.net>]
1420 *) Correct Win32 failure of mmap of a segment beyond start of the
1421 file; fixes large SSL and similar transfers. [William Rowe]
1424 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
1425 multi-process mode to not "daemonize" while detaching from the
1426 controlling terminal. This is necessary for Apache to work with
1427 process-management tools like AIX's "System Resource Controller"
1428 as well as Dan Bernstein's "daemontools".
1429 [Jos Backus <josb@cncdsl.com>, Aaron Bannert]
1431 *) Convert mod_auth_digest to use the new apr_global_mutex_t
1432 type. [Aaron Bannert]
1434 *) fix bug in mod-include where it wouldn't send a unmatched
1435 part if it was at the end of a bucket [Ian Holsman]
1437 *) worker MPM: Improve logging of errors with the interface between
1438 the listener thread and worker threads. [Jeff Trawick]
1440 *) Some browsers ignore cookies that have been merged into a
1441 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
1442 are now unmerged in the http proxy before being sent to the
1443 client. [Graham Leggett]
1445 *) Fix a problem with proxy where each entry of a duplicated
1446 header such as Set-Cookie would overwrite and obliterate the
1447 previous value of the header, resulting in multiple header
1448 values (like cookies) going missing.
1449 [Graham Leggett, Joshua Slive]
1451 *) Add the server-limit and thread-limit values to the scoreboard
1452 for the sake of third-party applications.
1453 [Adam Sussman <myddryn@vishnu.vidya.com>]
1455 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
1457 *) OS/390: Get make install to properly copy DSO modules.
1460 *) Win32: Fix bug in mod_status with displaying "Restart Time"
1461 and "Server uptime".
1464 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
1466 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
1468 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
1469 [David MacKenzie <djm@pix.net>]
1471 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
1472 [David MacKenzie <djm@pix.net>]
1474 *) Fix segfault and display error when SSLMutex file can not be
1475 created. [Adam Sussman <myddryn@vishnu.vidya.com>]
1477 *) Add reference counting to mod_mem_cache cache objects to
1478 better manage removing objects from the cache.
1481 *) Change the verbage on the ScoreBoardFile in our default configs.
1482 Also change the default to be commented out (unspecified) so we
1483 get anonymous shared memory by default. [Aaron Bannert]
1485 *) Implement new ScoreBoardFile directive logic. This affects how
1486 we create the scoreboard's shared memory segment. If the directive
1487 is present, a name-based segment is created. If the directive is
1488 not present, first an anonymous segment is created, and if that
1489 fails, a name-based segment is created from a file of the name
1490 DEFAULT_SCOREBOARD. This gives third-party applications the
1491 ability to access our scoreboard. [Aaron Bannert]
1493 *) Allow mod_deflate to work with non-GET requests and properly send
1494 Content-Lengths. [Sander Striker <striker@apache.org>]
1496 *) Fix ap_directory_merge() to correctly merge configs when there is
1497 no <Directory /> block. [Justin Erenkrantz, William Rowe]
1499 *) Remove spurious debug messsages that are normal under HTTP
1500 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
1502 *) Fix a bug in mod_cgid that would prevent proper shutdown death
1503 of the cgid process. [Aaron Bannert]
1505 *) Add signal handling back in to the worker MPM for the one_process
1506 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
1508 *) Performance: Reuse per-connection transaction pools in the
1509 worker MPM, rather than destroying and recreating them. [Brian Pane]
1511 *) Remove all signals from the worker MPM's child process. Instead,
1512 the parent uses the Pipe of Death for all communication with the
1513 child processes. [Ryan Bloom]
1515 Changes with Apache 2.0.32
1517 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
1518 default if the directive is not specified. This mirrors older
1519 behavior without changes to the httpd.conf. [William Rowe]
1521 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
1522 the service, mpm and logging code, and bugs in apr_file_open_stderr
1523 and apr_file_dup2 functions. Win2K/XP services have no handles
1524 associated for stdin/out/err, which caused unpredictable behavior
1525 in the prior release. [William Rowe, Bill Stoddard]
1527 *) Win32: simplify the Application Event Log messages, since there isn't
1528 likely to be 'more information in the error log' before an error log
1529 has been opened. [William Rowe]
1531 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
1532 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
1534 *) Win32: apache -k shutdown now behaves like apache -k stop.
1537 *) Fix prefork to not kill the parent if a child hits a resource shortage
1538 on accept(). [Greg Ames]
1540 *) Fix seg faults that occur when what should be the httpd request line
1541 starts with \r\n followed by garbage. [Greg Ames]
1543 *) Allow statically linked support binaries with the new
1544 --enable-static-support flag, and enable this behavior in
1545 the binbuild script. Also add a new --enable-static-htdbm
1546 flag. [Aaron Bannert]
1548 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
1549 do only one stat() call when generating the directory listings.
1552 *) Fix resolve_symlink to save the original symlink name if known.
1555 *) Be a bit more sane with regard to CanonicalNames. If the user has
1556 specified they want to use the CanonicalName, but they have not
1557 configured a port with the ServerName, then use the same port that
1558 the original request used. [Ryan Bloom and Ken Coar]
1560 *) In core_input_filter, check for an empty brigade after
1561 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
1562 client says it will post some data but we get FIN before any
1563 data arrives. [Jeff Trawick]
1565 *) Not being able to bind to the socket is a fatal error. We should
1566 print an error to the console, and return a non-zero status code.
1567 With these changes, all of the Unix MPMs do that correctly.
1570 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
1571 through to CGI scripts. PR 9163
1572 [Brian Reid <breid@customlogic.com>,
1573 Zvi Har'El <rl@math.technion.ac.il>]
1575 *) binbuild.sh: Make sure that we use the expat from our source
1576 tree so that there aren't any surprises on the target machine.
1579 *) mod_cgid: Add retry logic for when the daemon can't fork fast
1580 enough to keep up with new requests. Start using
1581 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
1582 when we can't talk to the daemon. [Jeff Trawick]
1584 *) apxs: LTFLAGS envvar can override default libtool options. Try
1585 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
1586 the covers. [Jeff Trawick]
1588 *) The Location: response header field, used for external
1589 redirect, *must* be an absoluteURI. The Redirect directive
1590 tested for that, but RedirectMatch didn't -- it would allow
1591 almost anything through. Now it will try to turn an abs_path
1592 into an absoluteURI, but it will correctly varf like Redirect
1593 if the final redirection target isn't an absoluteURI. [Ken Coar]
1595 Changes with Apache 2.0.31
1597 *) Create the scoreboard (in the parent) in a global pool context,
1598 so it survives graceful restarts. This fixes a SEGV during
1599 graceful restarts. [Aaron Bannert]
1601 *) Add a timeout option to the proxy code 'ProxyTimeout'
1604 *) FTP directory listings are now always retrieved in ASCII mode.
1605 The FTP proxy properly escapes URI's and HTML in the generated
1606 listing, and escapes the path components when talking to the FTP
1607 server. It is now possible to browse the root directory by using
1608 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
1609 Also, the last path component may contain wildcard characters
1610 '*' and '?', and if they do, a directory listing is created instead
1611 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
1614 *) Added single-listener unserialized accept support to the
1615 worker MPM [Brian Pane]
1617 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
1618 the incoming host header through to the proxied server
1619 [Geoff <g.russell@ieee.org>]
1621 *) New Directive Option for ProxyPass. It now can block a location
1622 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
1624 *) Don't let the default handler try to serve a raw directory. At
1625 best you get gibberish. Much worse things can happen depending
1626 on the OS. [Jeff Trawick]
1628 *) Change the pre_config hook to return a value. Modules can now emit
1629 an error message and then cause the server to quit gracefully during
1630 startup. This required a bump to the MMN. [Aaron Bannert]
1632 *) Fix some unix socket descriptor leaks in the handler side of
1633 mod_cgid (the part that runs in the server process). Whack a
1634 silly "close(-1)" in the handler too. [Jeff Trawick]
1636 *) Change the pre_mpm hook to return a value, so that scoreboard
1637 init errors percolate up to code that knows how to exit
1638 cleanly. This required a bump to the MMN. [Jeff Trawick]
1640 *) Add the socket back to the conn_rec and remove the create_connection
1641 hook. The create_connection hook had a design flaw that did not
1642 allow creating connections based on vhost info. [Bill Stoddard]
1644 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
1645 Resolves the common case of using negotation to resolve the request
1646 /script/foo for /script.cgi/foo. [William Rowe]
1648 *) Added new functions ap_add_(input|output)_filter_handle to
1649 allow modules to bypass the usual filter name lookup when
1650 adding hard-coded filters to a request [Brian Pane]
1652 *) caching should now work on subrequests (still very experimental)
1655 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
1657 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
1660 *) Refactor ap_rgetline so that it does not use an internal brigade.
1661 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
1663 *) Remove mod_auth_db. [Justin Erenkrantz]
1665 *) Do not install unnecessary pcre headers like config.h and internal.h.
1666 [Joe Orton <joe@manyfish.co.uk>]
1668 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
1669 (as it does for a normal request). quick_handled sub-requests now work
1670 in mod-include [Ian Holsman]
1672 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
1673 'CONTENT' one, as it needs to run AFTER all content headers
1675 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
1678 *) Split out blocking from the mode in the input filters.
1681 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
1683 *) Cause Win32 to capture all child-worker process errors in
1684 Apache to the main server error log, until the child can
1685 open its own error logs. [William Rowe]
1687 *) HPUX 11.*: Do not kill the child process when accept()
1688 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
1689 by [madhusudan_mathihalli@hp.com])
1692 *) Fix a problem in the parsing of the <Proxy foo> directive.
1695 *) rewrite of mod_ssl input filter for better performance and less
1696 memory usage [Doug MacEachern]
1698 *) allow quick_handler to be run on subrequests. [Ian Holsman]
1700 *) mod_dav now asks its provider to place content directly into the
1701 filter stack when handling a GET request. The mod_dav/provider
1702 API has changed, so providers need to be updated. [Greg Stein]
1704 *) Clear the output socket descriptor in unixd_accept() to make sure
1705 we don't supply a bogus socket to the caller if the accept fails.
1706 This caused problems with the worker MPM, which tried to process
1707 the returned socket if it was non-NULL. [Brian Pane]
1709 *) Move a check for an empty brigade to the start of core input filter
1710 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
1712 *) Add FileETag directive to allow configurable control of what
1713 data are used to form ETag values for file-based URIs. MMN
1714 bumped to 20020111 because of fields added to the end of
1715 the core_dir_config structure. [Ken Coar]
1717 *) Fix a segfault in mod_rewrite's logging code caused by passing the
1718 wrong config to ap_get_remote_host(). [Jeff Trawick]
1720 *) Allow mod_cgid to work from a binary distribution install by
1721 using 755 for the permissions on the log directory instead of
1724 *) Fixed a segfault that happened during graceful shutdown (or when
1725 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
1727 *) Split all Win32 modules [excluding the core components mod_core,
1728 mod_so, mod_win32 and the winnt mpm] into individual loadable
1729 modules, so the administrator may individually disable the former
1730 compiled-in modules by simply commenting out their LoadModule
1731 directives. [William Rowe]
1733 *) Saved Win32 module authors and porters many future headaches, by
1734 duplicating the appropriate .h files such as os.h into the include
1735 directory, including in the build tree. [William Rowe]
1737 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
1738 Use SSL functions/macros instead of directly dereferencing SSL
1739 structures wherever possible.
1740 Add type-casts for the cases where functions return a generic pointer.
1741 Add $SSL/include to configure search path.
1742 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1744 *) Moved several pointers out of the shared Scoreboard so it is
1745 more portable, and will present the vhost name across server
1746 generation restarts. [William Rowe]
1748 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
1751 Changes with Apache 2.0.30
1753 *) Fix the main bug for FreeBSD and threaded MPM's. There are
1754 still issues (see STATUS) but at least the server will now
1755 run without crashing the machine.
1756 [David Reid, Aaron Bannert, Justin Erenkrantz]
1758 *) Fix a typo in mod_deflate's m4 config section.
1759 [albert chin (china@thewrittenword.com)]
1761 *) Fix a couple of mod_proxy problems forwarding HTTP connections
1762 and handling CONNECT:
1763 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
1764 (2) Proxy failed to connect when the first IP address returned by
1765 the resolver was unreachable but a secondary IP address was.
1768 *) Fix the module identifer as shown in the docs for various core
1769 modules (e.g., the identifer for mod_log_config was previously
1770 listed as config_log_module). PR #9338
1771 [James Watson <ap2bug@sowega.org>]
1773 *) Fix LimitRequestBody directive by placing it in the HTTP
1774 filter. [Justin Erenkrantz]
1776 *) Fix mod_proxy seg fault when the proxied server returns
1777 an HTTP/0.9 response or a bogus status line.
1780 *) Prevent mod_proxy from truncating one character off the
1781 end of the status line returned from the proxied server.
1782 [Adam Sussman, Bill Stoddard]
1784 *) Eliminate loop in ap_proxy_string_read().
1785 [Adam Sussman, Bill Stoddard]
1787 *) Provide $0..$9 results from mod_include regex parsing.
1790 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
1792 *) Introduced the ForceLanguagePriority directive, to prevent
1793 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
1794 when using Multiviews. [William Rowe]
1796 *) Fix a problem which prevented mod_cgid and suexec from working
1797 together reliably [Greg Ames]
1799 *) Remove the call to exit() from within mod_auth_digest's post_config
1800 phase. [Aaron Bannert]
1802 *) Fix a problem in mod_auth_digest that could potentially cause
1803 problems with initialized static data on a system that uses DSOs.
1806 *) Fix a segfault in the worker MPM that could happen during
1807 child process exits. [Brian Pane, Aaron Bannert]
1809 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
1811 *) Fix matching of vhosts by ip address so we find IPv4
1812 vhost address when target address is v4-mapped form of
1813 that address. [Jeff Trawick]
1815 *) More performance tweaks to the BNDM string-search algorithm
1816 used to find "<!--#" tokens in mod_include [Brian Pane]
1818 *) Miscellaneous small performance fixes: optimized away various
1819 string copy operations and removed large temp buffers from
1820 the stack [Brian Pane]
1822 *) Fixed startup segfault that occurred when a VirtualHost
1823 directive had a port but no address [Brian Pane]
1825 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
1827 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
1828 if oslevel < WINNT. This should fix several problems reported
1829 Against 2.0.28 on Windows 98 [Bill Stoddard]
1831 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
1832 to fail. [Bill Stoddard]
1834 *) Change core code to allow an MPM to set hard thread/server
1835 limits at startup. prefork, worker, and perchild MPMs now have
1836 directives to set these limits. [Jeff Trawick]
1838 *) Win32: The async AcceptEx() event should be autoreset upon
1839 successful completion of a wait (WaitForSingleObject). This
1840 eliminates a number of spurious
1841 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
1844 *) Move any load library path environment variables out of
1845 apachectl and into a separate environment variable file which
1846 can be more easily tailored by the admin. The environment
1847 variable file as built by Apache may have additional system-
1848 specific settings. For example, on OS/390 we tailor the heap
1849 settings to allow lots of threads. [Jeff Trawick]
1851 *) Use the new APR pool code to reduce pool-related lock
1852 contention in the worker MPM. [Sander Striker]
1854 *) The POD no longer assumes the child is listening on 127.0.0.1
1855 and now pulls the first hostname in the list of listeners to
1856 perform the dummy connect on. This fixes a bug when the user
1857 had configured the Listen directive for an IP other than
1858 127.0.0.1. This would result in undead children and error
1859 messages such as "Connection refused: connect to listener".
1862 *) The worker MPM now respects the LockFile setting, needed to
1863 avoid locking problems with NFS. [Jeff Trawick]
1865 *) Fix segfault when worker MPM receives SIGHUP.
1866 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
1868 *) Fix bug that could potentially prevent the perchild MPM from
1869 working with more than one vhost/uid. [Aaron Bannert]
1871 *) Change make install and apxs -i processing of DSO modules to
1872 perform special handling on platforms where libtool doesn't install
1873 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
1874 which prevented standard LoadModule statements from working.
1877 *) Whenever mod_so is enabled (not just when there are DSOs for
1878 our modules), do whatever special magic is required for compiling/
1879 loading third-party modules. This allows third-party DSOs to
1880 be used on an AIX build when there were no built-in modules
1881 built as DSOs. (This should help on OS/390 and BeOS as well.)
1884 *) Allow apxs to be used to build DSOs on AIX without requiring the
1885 user to hard-code the list of import files. (This should help
1886 on OS/390 and BeOS as well.) [Jeff Trawick]
1888 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
1889 PR 8563, 8919 [William Rowe]
1891 *) Get binary builds working when libapr and libaprutil are built
1894 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
1895 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
1896 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
1898 *) Fix the handling of SSI directives in which the ">" of the
1899 terminating "-->" is the last byte in a file [Brian Pane]
1901 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
1902 message that we had back in apache-1.3 and still have scattered
1903 throughout our docs. [Aaron Bannert]
1905 *) Prevent the Win32 port from continuing after encountering an
1906 error in the command line args to apache. [William Rowe]
1908 *) On a error in the proxy, make it write a line to the error log
1911 *) Various mod_ssl performance improvements [Doug MacEachern]
1913 Changes with Apache 2.0.29
1915 *) Add buffering in core_output_filter to ensure that long
1916 lists of small buckets don't cause small packet writes.
1917 [Brian Pane, Ryan Bloom]
1919 *) Fix the installation target to make sure that the manual is
1920 installed in the correct location.
1921 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
1922 Gomez Henri <hgomez@slib.fr>]
1924 *) Fix the cmd command for mod_include. When we are processing
1925 a cmd command, we do not want to use the r->filename to set
1926 the command name. The command comes from the SSI tag. To do this,
1927 I added a variable to the function that builds the command line
1928 in mod_cgi. This allows the include_cmd function to specify
1929 the command line itself. [Ryan Bloom]
1931 *) Change open_logs hook to return a value, allowing you
1932 to flag a error while opening logs
1933 [Ian Holsman, Doug MacEachern]
1935 *) Change post_config hook to return a value, allowing you
1936 to flag a error post config
1937 [Ian Holsman, Jeff Trawick]
1939 *) Allow SUEXEC_BIN (the path to the suexec binary that is
1940 hard-coded into the server) to be specified to the configure
1941 script by the --with-suexec-bin parameter. [Aaron Bannert]
1943 *) Fix segv in worker MPM following accept on pipe-of-death
1946 *) Add mod_deflate to experimental.
1947 [Ian Holsman, Justin Erenkrantz]
1949 *) Bail out at configure time if an invalid MPM was specified.
1950 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1952 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
1953 configured [John Sterling <sterling@covalent.net>]

1959 *) Optimization for the BNDM string-search function in
1960 mod_include. [Brian Pane]
1962 *) Fixed the behavior of the XBitHack directive.
1963 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
1965 *) The threaded MPM for Unix has been removed. Use the worker
1966 MPM instead. [various]
1968 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
1969 in logging the error from a failed DNS lookup. [Jeff Trawick]
1971 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
1974 *) Get mod_cgid killed when a MPM exits due to a fatal error.
1977 *) Fix a file descriptor leak in mod_include. When we include a
1978 file, we use a sub-request, but we didn't destroy the sub-request
1979 immediately, instead we waited until the original request was
1980 done. This patch closes the sub-request as soon as the data is
1981 done being generated. [Brian Pane <bpane@pacbell.net>]
1983 *) Allow modules that add sockets to the ap_listeners list to
1984 define the function that should be used to accept on that
1985 socket. Each MPM can define their own function to use for
1986 the accept function with the MPM_ACCEPT_FUNC macro. This
1987 also abstracts out all of the Unix accept error handling
1988 logic, which has become out of synch across Unix MPMs.
1991 *) Fix a bug which would cause the response headers to be omitted
1992 when sending a negotiated ErrorDocument because the required
1993 filters were attached to the wrong request_rec.
1994 [John Sterling <sterling@covalent.net>]
1996 *) Remove commas from the end of the macros that define
1997 directives that are used by MPMs. Prior to this patch,
1998 you would use these macros without commas, which was unlike
1999 the macros for any other directives. Now, the caller provides
2000 the comma rather than the macro providing it. This makes
2001 the macros look more like the rest of the directives.
2002 [Ryan Bloom and Cliff Woolley]
2004 *) Add 'redirect-carefully' environment option to disable sending
2005 redirects under special circumstances. This is helpful for
2006 Microsoft's WebFolders when accessing a directory resource via
2007 DAV methods. [Justin Erenkrantz]
2009 *) Begin to abstract out the underlying transport layer.
2010 The first step is to remove the socket from the conn_rec,
2011 the server now lives in a context that is passed to the
2012 core's input and output filters. This forces us to be very
2013 careful when adding calls that use the socket directly,
2014 because the socket isn't available in most locations.
2017 *) Really reset the MaxClients value in worker and threaded
2018 when the configured value is not a multiple of the number
2019 of threads per child. We said we did previously but we
2020 forgot to. [Jeff Trawick]
2022 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
2024 *) If shared modules are requested and mod_so is not available,
2025 produce a fatal config-time error. [Justin Erenkrantz]
2027 *) Improve http2env's performance by cutting the work it has to
2028 do. [Brian Pane <bpane@pacbell.net>]
2030 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
2031 [Brian Pane <bpane@pacbell.net>]
2033 Changes with Apache 2.0.28
2035 *) Fix infinite loop in mod_cgid.c.
2036 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
2038 *) When no port is given in a "ServerName host" directive, the
2039 server_rec->port is now set to zero, not 80. That allows for
2040 run-time deduction of the correct server port (depending on
2041 SSL/plain, and depending also on the current setting of
2042 UseCanonicalName). This change makes redirections
2043 work, even with https:// connections. As in Apache-1.3, the
2044 connection's actual port number is never used, only the ServerName
2045 setting or the client's Host: setting. Documentation updated
2046 to reflect the change. [Martin Kraemer]
2048 *) Add a '%{note-name}e' argument to mod-headers, which works in
2049 the same way as mod_log_confg. [Ian Holsman]
2051 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
2052 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
2053 MPMs. [Cliff Woolley]
2055 *) Introduce htdbm, a user management utility for db/dbm authorization
2056 databases. [Mladen Turk <mturk@mappingsoft.com>]
2058 *) Optimize usage of strlen and strcat in ap_directory_walk.
2059 [Brian Pane <bpane@pacbell.net>]
2061 Changes with Apache 2.0.27
2063 *) Introduce an Apache mod_ssl initial configuration template
2064 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
2066 *) Fixed a memory leak in the getline parsing code that could
2067 be triggered by arbitrarily large header lines. Requests
2068 from the core input filter for single lines are now limited
2069 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
2071 *) Fix a truncation bug in how we print the port on the Via: header.
2072 The routine that prints the Via: header now takes a length for
2073 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
2075 *) Some syntax errors in mod_mime_magic's magic file can result
2076 in a 500 error, which previously was unlogged. Now we log the
2077 error. [Jeff Trawick]
2079 *) Add the support/checkgid helper app, which checks the run-time
2080 validity of group identifiers usable in the Group directive.
2083 *) Various --enable-so options have been fixed: --enable-so is
2084 treated as "static"; explicit --enable-so=shared issues an error;
2085 and explicit --enable-so fails with error on systems without
2086 APR_HAS_DSO. [Aaron Bannert]
2088 *) Fix a segfault in the core input filter when the client socket
2089 gets disconnected unexpectedly. [Cliff Woolley]
2091 *) Fix the reporting for child processes that die. This removes
2092 all of the non-portable W* macros from Apache.
2093 [Jeff Trawick and Ryan Bloom]
2095 *) Win32: Track and display "Parent Server Generation:" in
2096 mod_status output. The generation will be bumped at
2097 server graceful restart, when the child process exits
2098 by hitting MaxRequestsPerChild or if the child
2099 process exits abnormally. [Bill Stoddard]
2101 *) Win32: Fix problem where MaxRequestsPerChild directive was
2102 not being picked up in favor of the default. Enable
2103 the parent to start up a new child process immediately upon
2104 the old child starting shutdown.
2107 *) Fix some bungling of the remote port in rfc1413.c so that
2108 IdentityCheck retrieves the proper user id instead of failing
2109 and thus always returning "nobody."
2110 [Dick Streefland <Dick.Streefland@xs4all.nl>]
2112 *) Introduced thread saftey for mod_rewrite's internal cache.
2113 [Brian Pane <bpane@pacbell.net>]
2115 *) Simplified mod_env's directives to behave as most directives are
2116 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
2117 directive following that UnsetEnv within the same container.
2118 Also provides a runtime startup warning if a PassEnv configured
2119 environment value is undefined. [William Rowe]
2121 *) The worker MPM is now completely ported to APR's new lock API. It
2122 uses native APR types for thread mutexes, cross-process mutexes,
2123 and condition variables. [Aaron Bannert]
2125 *) Sync up documentation to remove all references to the now deprecated
2126 Port directive. [Justin Erenkrantz]
2128 *) Moved all ldap modules from the core to httpd-ldap sub-project
2131 *) Exit when we can't listen on any of the configured ports. This
2132 is the same behavior as 1.3, and it avoids having the MPMs to
2133 deal with bogus ap_listen_rec structures. [Jeff Trawick]
2135 *) Cleanup the proxy code that creates a request to the origin
2136 server. This change adds an optional hook, which allows modules
2137 to gain control while the request is created if the proxy module
2138 is loaded. The purpose of this hook is to allow modules to add
2139 input and/or output filters to the request to the origin. While
2140 I was at it, I made the core use this hook, so that proxy request
2141 creation uses some of the code from the core. This can still be
2142 greatly improved, but this is a good start. [Ryan Bloom]
2144 Changes with Apache 2.0.26
2146 *) Port the MaxClients changes from the worker MPM to the threaded
2149 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
2150 with the new input filtering system. [Justin Erenkrantz]
2152 *) Introduce the MultiviewsMatch directive, to allow the operator
2153 to be flexible in recognizing Handlers and Filters filename
2154 extensions as part of the Multiviews matching logic, strict with
2155 MultiviewsMatch NegotiatedOnly to accept only filename extentions
2156 that designate negotiated parameters, (content type, charset, etc.)
2157 or MultiviewsAll for the 1.3 behavior of matching any files, even
2158 if they have unregistered extensions. [William Rowe]
2160 *) Fixed the configure script to add a LoadModule directive to
2161 the default httpd.conf for any module that was compiled
2162 as a DSO. [Aaron Bannert <aaron@clove.org>]
2164 *) rewrite mod_ssl input filtering to work with the new input filtering
2165 system. [Justin Erenkrantz]
2167 *) prefork: Don't segfault when we are able to listen on some but
2168 not all of the configured ports. [Jeff Trawick]
2170 *) Build mod_so even if no core modules are built shared.
2171 [Aaron Bannert <aaron@clove.org>]
2173 *) Introduce ap_directory_walk rewrite (with further optimizations
2174 required) to adapt to the ap_process_request_internal() changes.
2175 Optimized so subrequests and redirects now reuse previous section
2176 merges, until we mismatch with the original directory_walk, and
2177 precomputed r->finfo results will cause directory_walk to skip
2178 the most expensive phases of the function. [William Rowe]
2180 *) Allow ApacheMonitor to connect to and control Apache on other
2181 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
2183 *) Remove the Port directive. In it's place, the Listen directive
2184 is now a required directive, which tells Apache what port to
2185 listen on. The ServerName directive has also been extended
2186 to accept an optional port. If the port is specified to the
2187 ServerName, the server will report that port whenever it
2188 reports the port that it is listening on. This change was
2189 made to ease configuration errors that stem from having a Port
2190 directive, and a Listen directive. In that situation, the server
2191 would only listen to the port specified by the Listen command,
2192 which caused a lot of confusion to users. [Ryan Bloom]
2194 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
2195 build, as loadable modules. [William Rowe]
2197 *) Fix --enable-mods-shared processing. If most is specified,
2198 then all modules that can be compiled as shared modules are.
2199 [Aaron Bannert <aaron@clove.org>]
2201 *) Update the mime.types file to map video/vnd.mpegurl to mxu
2202 and add commonly used audio/x-mpegurl for m3u extensions.
2203 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
2205 *) Eliminate the depreciated r->content_language, in favor of the array
2206 r->content_languages introduced many years ago. Module authors must
2207 substantially overhaul their modules, so this needs to be upgraded
2208 if the module still relied on backwards-brokeness. [William Rowe]
2210 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
2213 *) Rewrite the input filtering mechanisms to consolidate and reorganize
2214 code. In short, core_input_filter does something now and
2215 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
2217 *) Update the Win32 build to re-absorb mod_proxy and family.
2220 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
2221 current SDK.) [William Rowe]
2223 *) Some style changes to the code that does ProxyErrorOverride. Fixed
2224 config merge behaviour. [Graham Leggett]
2226 *) Allow support programs to be compiled against a static version
2227 of libapr. This allows the smaller support programs to be
2228 relocated. [Aaron Bannert <aaron@clove.org>]
2230 *) Update the mime.types file to the registered media types as
2231 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
2233 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
2234 number of clients that can connect at the same time, instead of
2235 specifying the maximum number of child processes.
2236 [Aaron Bannert <aaron@clove.org>]
2238 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
2239 be consistent with 1.3. [Justin Erenkrantz]
2241 *) Cache apr_explode_localtime() value for 15 seconds.
2242 [Brian Pane <bpane@pacbell.net>]
2244 *) Fix mod_include to not return ETag or Last-Modified headers.
2245 [Ian Holsman <ianh@cnet.com>]
2247 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
2249 *) Eliminate the wasteful run-time conversion of method names from strings
2250 to numbers in places where the methods are known at compile time.
2251 [Brian Pane <bpane@pacbell.net>]
2253 *) Turn the worker MPM's queue into a LIFO. This may
2254 improve cache-hit performance under some conditions.
2255 [Aaron Bannert <aaron@clove.org>]
2257 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
2258 support it. [Justin Erenkrantz]
2260 *) Cleanup the worker MPM. We no longer re-use transaction
2261 pools. This incurs less overhead than shuffling the pools
2262 around so that they can be re-used. Remove one of the
2263 queue's condition variables. We just redefined the API to
2264 state that you can't try to add more stuff than you allocated
2265 segments for. [Aaron Bannert <aaron@clove.org>]
2267 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
2269 *) Fixed persistent connections when a request contains a body.
2272 *) mod_dav uses a new API to speak to the backend provider for dead
2273 property management. [Greg Stein]
2275 *) Remove the Win32 script-processing exception from mod_cgi, and
2276 roll build_command_line/build_argv_list into a unified, overrideable
2277 ap_cgi_build_command optional function. [William Rowe]
2279 *) Rewrite find_start_sequence to use a better search algorithm
2280 to find the start tag. [Justin Erenkrantz]
2282 *) Fix a seg fault in mod_include. When we are generating an
2283 internal redirect, we must set r->uri to "", not a bogus
2284 string, and not NULL. [Ryan Bloom]
2286 *) Optimized location_walk, so subrequests, redirects and second passes
2287 now reuse previous section merges on a <Location > by <Location >
2288 basis, until we mismatch with the original location_walk.
2291 *) Back out the 1.45 change to util_script.c. This change made
2292 us set the environment variable REQUEST_URI to the redirected
2293 URI, instead of the originally requested URI.
2294 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2296 *) Make mod_include do lazy evaluation of potentially expensive to
2297 compute variables. [Brian Pane <bpane@pacbell.net>]
2299 *) Fix logging of bytes sent for HEAD requests. %b and %B should
2300 log either - or 0, before this patch, they were both logging
2301 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2303 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
2304 than per character. [Brian Pane <bpane@pacbell.net>]
2306 *) Normalize the primary request, redirects and sub-requests to
2307 run the same ap_process_request_internal for consistency in
2308 robustness, behavior and security. [William Rowe]
2310 *) Fix a segfault with mod_include when r->path_info is not set
2311 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
2313 *) Add -X functionality back. This indicates to all MPMs and any other
2314 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
2316 *) Some initial support for the cygwin platform [prefork only].
2317 This is not to be confused with support for the WinNT/Win32
2318 platform, which is the recommended configuration for native
2319 Win32 users. The cygwin platform support is recommended for
2320 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
2322 *) Changed syntax of Set{Input|Output}Filter. The list of filters
2323 must be semicolon delimited (if more than one filter is given.)
2324 The Set{Input|Output}Filter directive now overrides a parent
2325 container's directive (e.g. SetInputFilter in <Directory /web/foo>
2326 will override any SetInputFilter directive in <Directory /web>.)
2327 This new syntax is more consistent with Add{Input|Output}Filter
2328 directives defined in mod_mime. Also cures a bug in prior releases
2329 where the Set{Input|Output}Filter directive would corrupt the
2330 global configuration if the multiple directives were nested.
2333 *) Cured what's ailed mime for quite some time. If an AddSomething
2334 was given in the configuration (Language, Charset, Handler or
2335 Encoding) Apache would set the content type as given by AddType,
2336 but refused to check the mime.types file if AddType wasn't given
2337 for that specific extension. Setting the AddHandler for .html
2338 without setting the AddType text/html html would cause Apache to
2339 use the default content type. [William Rowe]
2341 *) Added some bulletproofing to memory allocation in the LDAP cache
2342 code. [Graham Leggett]
2344 Changes with Apache 2.0.25
2346 *) Move the installed /manual directory out of the /htdocs/ tree, so
2347 that it can be kept more independently from the remaining document
2348 root. The "Alias /manual ..." already allowed for easy projection
2349 into existing private document trees. [Martin Kraemer]
2351 *) Add specified user attributes to the environment when using
2352 mod_auth_ldap. This allows you to use mod_include to embed specified
2353 user attributes in a page like so:
2354 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
2357 *) Fix a performance problem with the worker MPM. We now create
2358 transaction pools once, and re-use them for each connection.
2359 [Aaron Bannert <aaron@clove.org>]
2361 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
2362 of a 'handler' or 'filter', so that any filename extension that does
2363 not contribute to the negotiated metadata can't be served without
2364 an explicit request. E.g., if the .Z extension is associated with
2365 an unzip filter, the user request somefile.Z.html, mod_negotiation
2366 won't serve it. It can serve somefile.Z.html when somefile.Z is
2367 requested, since the .Z extension is explictly requested, if the
2368 .html extension is associated with ContentType text/html.
2371 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
2372 and corresponding AddOutputFilter syntax, to insert one or more
2373 filters by mod_mime filename extension processing.
2376 *) Fix a growing connection pool in core_output_filter() for
2377 keepalive requests. [Jeff Trawick]
2379 *) Moved split_and_pass_pretag_buckets back to being a
2380 macro at Ryans's request. Removed the return from it
2381 by setting and returning a return code instead. Updated
2382 the code to check the return code from the macro and
2383 do the right thing. [Paul J. Reder]
2385 *) Fix a segfault when a numeric value was received for Host:.
2388 *) Add a function ap_remove_input_filter. This is to match
2389 up with ap_remove_output_filter. [Ryan Bloom]
2391 *) Clean up location_walk, so that this step performs a minimum
2392 amount of redundant effort (it must be run twice, but it will no
2393 longer reparse all <Location > blocks when the request uri
2394 hadn't changed.) [William Rowe]
2396 *) Eliminate proxy: (and all other 'special') processing from the
2397 ap_directory_walk() phase. Modules that want to use special
2398 walk logic should refer to the mod_proxy map_to_location example,
2399 with it's proxy_walk and proxysection implementation. This makes
2400 either directory_walk flavor much more legible, since that phase
2401 only runs against real <Directory > blocks.
2404 *) SECURITY: Fix a security problem in mod_include which would allow
2405 an SSI document to be passed to the client unparsed.
2406 [Cliff Woolley, Brian Pane]
2408 *) Introduce the map_to_storage hook, which allows modules to bypass
2409 the directory_walk and file_walk for non-file requests. TRACE
2410 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
2411 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
2414 *) Add the ability for mod_include to add the INCLUDES filter
2415 if the file is configured for the server-parsed handler.
2416 This makes the configuration for .shtml files much easier
2417 to understand, and allows mod_include to honor Apache 1.3
2418 config files. Based on Doug MacEachern's patch to PHP
2419 to do the same thing. [Ryan Bloom]
2421 *) force OpenSSL to ignore process local-caching and to always
2422 get/set/delete sessions using mod_ssl's callbacks
2423 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
2424 Geoff Thorpe <geoff@geoffthorpe.net>]
2426 *) Make the worker MPM shutdown and restart cleanly. This also
2427 cleans up some race conditions, and gets the worker using
2428 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
2430 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
2432 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2434 *) Fix for mod_include. Ryan's patch to check error
2435 codes put a return in the wrong place. Also, the
2436 include handler return code wasn't being checked.
2437 I don't like macros with returns, so I converted
2438 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
2439 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2441 *) fix segv in mod_mime if no AddTypes are configured
2442 [John Sterling <sterling@covalent.net>]
2444 *) Enable ssl client authentication at SSL_accept time
2445 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2447 *) Fix a segfault in mod_include when the original request has no
2448 associated filename (e.g., we're filtering the error document for
2449 a bad URI). [Jeff Trawick]
2451 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
2453 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
2454 of httpd is started and shuts down due to socket conflict. Moving the
2455 call to ap_log_pid solves the problem.
2457 *) Changed the late-1.3 log_config substitution %c to %X, to log the
2458 status of the closed connection, as it conflicts with the far more
2459 common, historical ssl logging directive %...{var}c. [William Rowe]
2461 *) Added the common error/ tree to the build/install targets
2462 (similar to the common icons/ tree) for the multi-language error
2463 messages that Lars committed earlier. [William Rowe]
2465 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
2467 *) Added a default commented-out mod_ldap and mod_auth_ldap
2468 configuration to httpd-std.conf and httpd-win.conf
2471 *) Added documentation for mod_ldap and mod_auth_ldap.
2474 *) Enabled negative caching on attribute comparisons in the LDAP cache.
2475 Fixed a problem where the default cache TTL was set in milliseconds
2476 not microseconds causing the cache to time out almost immediately.
2479 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
2480 module code to follow APR. [Graham Leggett]
2482 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
2483 cleaned up when the connection pool pool is cleaned up.
2486 *) Fix a minor issue with Jeff Trawick's mod_include
2487 patch. Without this patch, the code will just allocate
2488 more bytes in get_combined_directive than are needed.
2491 *) Added the LDAP authentication module mod_auth_ldap.
2492 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
2494 *) Added the LDAP cache and connection pooling module mod_ldap.
2495 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
2497 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
2498 by allowing a module to disable itself if its prerequisites are not
2499 met. [Justin Erenkrantz]
2501 Changes with Apache 2.0.24
2503 *) Fix a couple of issues in mod_include when the tag appeared at
2504 offsets near 8192 in the file being parsed. [Jeff Trawick]
2506 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
2507 reached. [Jeff Trawick]
2509 *) Numerous improvements to the Win32 build system. Introduced command line
2510 builds without requiring .mak files for MSVC 6.0 and later versions.
2511 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
2514 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
2515 reporting of uninstalled services and other error conditions, and changed the
2516 default service name to Apache2. [William Rowe]
2518 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
2519 compatibility with existing Apache 1.3 Win32 Apache management utilites.
2520 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
2522 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
2523 [William Rowe, Greg Ames]
2525 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
2526 and RemoveCharset directives. [William Rowe]
2528 *) The Unix MPMs other than perchild now allow child server
2529 processes to use the accept mutex when starting as root and
2530 using SysV sems for the accept mutex. Previously, this
2531 combination would lead to fatal errors in the child server
2532 processes. perchild can't use SysV sems because of security
2533 issues. [Jeff Trawick, Greg Ames]
2535 *) Added Win32 revision stamp resources to all http binaries
2536 (including modules/ and support/ tools.) PR7322 [William Rowe]
2538 *) Fix ap_rvprintf to support more than 4K of data at one time.
2539 [Cody Sherr <csherr@covalent.net>]
2541 *) We have always used the obsolete/deprecated Netscape syntax
2542 for our tracking cookies; now the CookieStyle directive
2543 allows the Webmaster to choose the Netscape, RFC2109, or
2544 RFC2965 format. The new CookieDomain directive allows the
2545 setting of the cookie's Domain= attribute, too. PR #s 5006,
2546 5023, 5920, 6140 [Ken Coar]
2548 *) Tweak server/Makefile so that the rules for generating exports.c
2549 are compatible with make utilities which don't expand wildcards
2550 in a dependency list (e.g., OS/390 make, certain levels of GNU
2551 make). [Jeff Trawick]
2553 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
2555 *) Begin to sanitize the MPM configuration directives. Now, all
2556 MPMs use the same functions for all common MPM directives. This
2557 should make it easier to catch all bugs in these directives once.
2558 [Cody Sherr <csherr@covalent.net>]
2560 *) Close a major resource leak. Every time we had issued a
2561 graceful restart, we leaked a socket descriptor.
2564 *) Fix a problem with the new method code. We need to cast
2565 the 1 to an apr_int64_t or it will be treated as a 32-bit
2566 integer, and it will wrap after being shifted 32 times.
2567 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
2569 *) Fix a bug in mod_expires. Previous to this patch, if you
2570 told mod_expires to add 604800 seconds to the last-modified
2571 time, it actually added 604800 usec's to the last-modified time,
2572 so that when looking at the response it looked like nothing
2573 had been done. The root of the problem was that we always compute
2574 time in usec's, but we ask users to input sec's. This means we
2575 need to convert to usec's before using those values.
2578 *) The worker MPM now handles shutdown and restart requests. It
2579 definitely isn't perfect, but we do stop the servers correctly.
2580 The biggest problem right now is that SIGHUP causes the server to
2581 just die. [Ryan Bloom]
2583 Changes with Apache 2.0.23
2585 *) Use the prefork MPM by default on Unix. [various]
2587 *) Added a systray icon monitor application for Win32.
2588 [Mladen Turk <mturk@mappingsoft.com>]
2590 *) mod_rewrite: Fix the line ending on some non-Unix systems for
2591 messages written to the rewrite log.
2592 [Richard Labennett <rlabenn@us.ibm.com>]
2594 *) All mod_autoindex query parsing is now quietly quashed with the
2595 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
2596 still drops the column sort <a href>'s for the column headers, but
2597 IgnoreClient is required to ignore these Query options entirely.
2600 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
2601 to allow the client to select plain, FancyIndexing or HTMLTable
2602 formatting, V=[0|1] to inhibit or enable version sorting, and
2603 P=pattern to return only specific files. The old Query Arguments
2604 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
2605 as before), and O=A|D for ordering ascending or descending.
2608 *) Fixed an error in mod_include's directive parsing routines which
2609 caused #if, #elif, and #else expressions containing backslashes
2610 to be improperly evaluated. [Cliff Woolley]
2612 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
2613 drop the icon column, SuppressRules to drop the <hr> elements,
2614 and HTMLTable to create rudimentary HTML table listings (implies
2615 FancyIndexing). [William Rowe]
2617 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
2618 from Apache 1.3.15. This is needed for two reasons, first, given
2619 multiple machines within a server farm, ETags and Last-Modified
2620 stamps won't correspond from machine to machine, and second, many
2621 Unixes don't capture changes to the date or time stamp of existing
2622 files, since these don't modify the dirent itself. [William Rowe]
2624 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
2625 and DirectoryWidth options from Apache 1.3.10.
2626 [William Rowe, Ken Coar]
2628 *) Eliminated FancyIndexing directive, deprecated early in Apache
2629 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
2631 *) mod_autoindex now excludes any file names that would result in
2632 an error, other than a success or redirect. Also optimized
2633 the parent directory, always included except in the URI '/'.
2636 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
2637 negotiated index pages, and prevent the server from defaulting
2638 to an autoindex of the directory. mod_negotiation will now die
2639 with a 500 Internal Error if it could match some filenames
2640 (e.g. for mod_dir) but none can be served. mod_negotation now
2641 refuses to serve any file with an extention that mod_mime doesn't
2642 recognize, and wasn't part of the request. [William Rowe]
2644 *) Eliminate mod_cgi's handling of .exe files without the .exe file
2645 extension. This is already handled by multiviews, if the admin
2646 wishes to AddHandler .exe or define a content type handler and
2647 associate .exe files with that content type. Multiviews must be
2648 enabled to allow these to be served. [William Rowe]
2650 *) Speed up the server's response to a spike in incoming workload
2651 or restarts by assigning empty scoreboard slots to new processes
2652 when they are available. [Greg Ames]
2654 *) Add a handler to mod_includes.c. This handler is designed to
2655 implement the XbitHack directive. This can't be done with a
2656 fixup, because we need to check the content-type, which is
2657 only available in the handler phase. [Ryan Bloom]
2659 *) Make the includes filter check return codes from filters lower in
2660 the filter chain. If a lower level filter returns an error, then
2661 the request needs to stop immediately. This allows mod_include to
2662 stop parsing data once a lower filter recognizes an error.
2665 *) Add the ability to extend the methods that Apache understands
2666 and have those methods <limit>able in the httpd.conf. It uses
2667 the same bit mask/shifted offset as the original HTTP methods
2668 such as M_GET or M_POST, but expands the total bits from an int to
2669 an ap_int64_t to handle more bits for new request methods than
2670 an int provides. [Cody Sherr <csherr@covalent.net>]
2672 *) Fix broken mod_mime behavior in merging its arguments. Possible
2673 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
2675 *) Solve many mod_ssl porting issues (too many to detail) with
2676 help from the whole team, but most notably [Ralf S. Engelschall,
2677 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
2678 Doug MacEachern, William Rowe, Cliff Woolley]
2680 *) More stall fixes for the threaded & worker mpm's.
2681 Make mod_status output more accurate. Don't
2682 count workers in processes which aren't actively
2683 serving requests. [Greg Ames]
2685 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
2687 *) Add a single listener/multiple worker MPM. This MPM is
2688 definately not fully correct, but it allows us to solve many
2689 of the problems that exist in the threaded MPM. This is a
2690 modified version of the threaded MPM. [Ryan Bloom]
2692 *) Improve content generation throughout Apache, providing closer
2693 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
2694 Transitional specifications. [William Rowe]
2696 Changes with Apache 2.0.22
2698 *) Fix a problem where the threaded MPM stalls after restarts or
2699 segfaults. Also prevent multiple active processes from using
2700 the same scoreboard slot. [Greg Ames]
2702 *) Apache/Win32 now fills in the service description with Apache's
2703 server version string, including loaded and advertised modules.
2706 *) Improved support for the Win32 build, to recover gracefully from
2707 missing apr or apr-util directories or the awk interpreter,
2708 create the proper cgi-bin examples, including a test-cgi.bat, and
2709 fix the perl shebang line for printenv.pl, when installing from
2710 the build environment. [William Rowe]
2712 *) Fix a segfault in threaded.c caused by passing uninitialized
2713 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
2715 *) Use new APR number conversion functions to reduce CPU consumption
2716 when setting the content length, and in mod_log_config.
2719 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
2720 where HEAD response headers were being repeated twice for
2721 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
2722 problem in the http_header filter was exposed by the recent rewrite
2723 of the content_length filter. [Taketo Kabe, Bill Stoddard]
2725 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
2726 restarts. A garbage pointer to a vhost's server_rec from the
2727 previous generation was being left around under certain
2728 conditions. [Greg Ames]
2730 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
2731 used to appear as '(none', without the closing paren.
2732 [Günter Knauf <eflash@gmx.net>]
2734 *) Improve the exports generating awk script. In the past, we had
2735 work around problems in the awk script by avoiding some #if and
2736 #ifdefs. This has bitten us many times in generating the exports.c
2737 file. This improvement allows corrects the header file parsing.
2738 [Sander Striker <striker@apache.org>]
2740 Changes with Apache 2.0.21
2742 *) Resolve the Win32 htpasswd bug, where a file that existed would be
2743 overwritten, regardless of the -c flag.
2744 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
2746 *) Introduce connection sub-pools into ab. Truncating the lifetime
2747 of these allocations means that ab no longer perpetually grows
2748 its working set, running out of memory on large request attempts.
2751 *) Make scoreboard creation a hook. This allows management
2752 modules to have access to the scoreboard at the time that it is
2753 created, and at every restart request.
2754 [Cody Sherr <csherr@covalent.net>]
2756 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
2757 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
2758 daemon index actually used in the scoreboard. I also
2759 updated the pertinent calls. [Paul J. Reder]
2761 *) Win32: Prevent listening sockets from being inherited by
2762 the Apache child process, CGI scripts, rotatelog process
2763 etc. If the Apache child process segfaults, any processes
2764 that the child started are not reaped. Prior to this fix,
2765 these processes inherited the listening sockets which sometimes
2766 prevented the restarted Apache child process from accepting
2767 connections (ie, the server would hang).
2770 *) Provide vhost and request strings when ExtendedStatus is on.
2773 *) Fix some issues with the pod and prefork: check the pod *after*
2774 processing a connection so that a server processing a time-
2775 consuming request bails out as soon as practical; when the
2776 parent process wakes up a server process via connect(), use an
2777 APR timeout on the connect() so that we don't hang for a long
2778 time if there aren't server processes around to do accept().
2779 [Jeff Trawick, Greg Ames]
2781 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
2782 spends a lot of time in apr_table_get calls. Using the default
2783 httpd.conf, the tables for languages and charsets are somewhat
2784 large, so the time spent scanning them on each request is
2785 significant. Replacing the tables with hash tables provides
2786 a nice speedup. [Brian Pane <bpane@pacbell.net>]
2788 *) Add two functions to allow modules to access random parts of the
2789 scoreboard. This allows modules compiled for one MPM to access the
2790 scoreboard, even if it the server was compiled for another MPM.
2791 [Harrie Hazewinkel <harrie@covalent.net>]
2793 Changes with Apache 2.0.20
2795 *) Fix problem in content-length filter where the filter would
2796 buffer all the output from a CGI before sending any bytes
2797 down the filter stack to the network. This problem would cause
2798 significant memory consumption if the CGIs generated
2799 lots of bytes. [Bill Stoddard]
2801 *) Get non-blocking CGI pipe reads working with the bucket brigades.
2804 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
2807 *) Fix a bug in the threaded MPM that would cause it to kill off all
2808 workers immediately after starting if the number of workers started
2809 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
2811 Changes with Apache 2.0.19
2813 *) Fix problem with threaded MPM. The problem was that if each child
2814 process was busy serving a single long-lived request and the server
2815 was sent a graceful restart signal, the server would stop serving
2816 requests. This would happen because each child process would wait to
2817 die until the last thread was done, and the parent wouldn't spawn any
2818 new children until a process died. Now, the parent looks at the fact
2819 that the children are dying gracefully, and starts new children.
2820 Those new children only start enough threads to compliment the number
2821 of threads in the other child process that shares the same spot in
2822 the scoreboard. In this way, we make sure to never go over
2823 MaxClients. [Ryan Bloom]
2825 *) modified mod_negotiation and mod_autoindex to speed up by almost a
2826 factor of two on apr_dir_read()-enhanced platforms, such as Win32
2827 and OS2, by calling ap_sub_request_lookup_dirent() with the results
2828 already provided by apr_dir_read(). [William Rowe]
2830 *) mod_file_cache is now more robust to filtering and serves requests
2831 slightly more efficiently. [Cliff Woolley]
2833 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
2834 Module was calling ap_rwrite() followed by ap_rflush() but the
2835 served content was not being displayed in the browser. Inspection
2836 of the output stream revealed that the first data chunk was
2837 missing the trailing CRLF required by the RFC. [Bill Stoddard]
2839 *) apxs no longer generates ap_send_http_header() in the example handler
2841 *) Fix an ab problem which could cause a divide-by-zero exception
2842 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
2843 [Ian Holsman <ianh@cnet.com>]
2845 *) Solve case-insensitive platforms' confusion about negotiated
2846 filenames, allowing files of differnt case to match in choosing
2847 the document to serve. [William Rowe]
2849 *) Fix brokenness when ThreadsPerChild is higher than the built-in
2850 limit. We left ap_threads_per_child at the higher value which
2851 led to segfaults when doing certain scoreboard operations.
2854 *) Fix seg faults and/or missing output from mod_include. The
2855 default_handler was using the subrequest pool for files and
2856 MMAPs, even though the associated APR structures typically
2857 live longer than the subrequest. [Greg Ames]
2859 *) Extend mod_setenvif to support specifying regular expressions
2860 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
2861 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
2862 will cause HAVE_TS to be set if any of the request headers begins
2863 with "TS" and has a value that begins with any character in the
2864 set [a-z]. [Bill Stoddard]
2866 *) httpd children now re-bind themselves to a random CPU on
2867 multiprocessor systems on AIX via bindprocessor() in 2.0.
2868 [Victor J. Orlikowski]
2870 *) Fix htdigest. It would go into a loop in getline when adding
2871 a second user. [Bill Stoddard]
2873 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
2875 *) Automatically generate httpd.exp for AIX.
2876 DSOs now work again on AIX in 2.0
2877 [Victor J. Orlikowski]
2879 *) Add a new request hook, error_log. This phase allows modules
2880 to act on the error log string _after_ it has been written
2881 to the error log. The goal for this hook is to allow monitoring
2882 modules to send the error string to the monitoring agent.
2885 *) Modify mod_echo to make it use filters for input and output.
2886 [Ryan Morgan <rmorgan@covalent.net>]
2888 *) Extend mod_headers to support conditional driven Header
2889 add, append and set. Use SetEnvIf to set an envar and conditionally
2890 add/append/set headers based on this envar thusly:
2892 SetEnvIf TSMyHeader value HAVE_TSMyHeader
2893 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
2895 If the request contains header "TSMyHeader: value" then header
2896 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
2899 *) Extend mod_headers to support using format specifiers on Header
2900 add, append and set header values. Two format specifiers are supported:
2902 %t - reports, in UTC microseconds since the epoch, when the
2903 request was received.
2905 %D - reports the time, in microseconds, between when the request was
2906 received and the response sent.
2909 Header add MyHeader "This request served in %D microseconds. %t"
2911 results in a header being added to the response that looks like this:
2913 MyHeader: This request served in D=5438 microseconds. t=991424704447256
2917 *) Fix reset_filter(). We need to be careful how we remove filters.
2918 If we set r->output_filters to NULL, we also have to reset the
2919 connection's filters. [John Sterling]
2921 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
2923 *) Add a check to ap_die() to make sure the filter stack is sane and
2924 contains the correct basic filters when an error occurs. This fixes
2925 a problem where headers are not being sent on error. [John Sterling]
2927 *) New Header directive 'echo' option. "Header echo regex" will
2928 cause any headers received on the request that match regex to be
2929 echoed to (included in) the response headers.
2932 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
2933 This prevented the inclusion of apr_compat.h. PR #7773
2934 [Oleg Broytmann <phd@phd.pp.ru>]
2936 *) Moved util_uri to the apr-util library. This required a bunch of
2937 apr_name changes for the uri utility functions. [Justin Erenkrantz]
2939 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
2940 insert_filter phase so that other filters are not bypassed by default.
2943 *) Reimplement mod_headers as an output filter. mod_headers can now
2944 add custom headers to inbound requests using the RequestHeader directive
2945 and to responses using the same old Header directive. [Graham Leggett]
2947 Changes with Apache 2.0.18
2949 *) Fix command-line processing so that if a bad argument is specified
2950 Apache will exit. [Jeff Trawick]
2952 *) Change the make targets and rules to be consistent in all of the
2953 Apache-owned source trees. [Roy Fielding]
2955 *) Fix processing of the TRACE method. Previously we passed bogus
2956 parms to form_header_field() and it overlaid some vhost structures,
2957 resulting in a segfault in check_hostalias().
2958 [Greg Ames, Jeff Trawick]
2960 *) Win32: Add support for reliable piped logs. If the logging process
2961 goes down, Apache will automatically restart it. This function has
2962 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
2965 *) Do not start piped log processes during the config file
2966 preflight. This change also circumvents a problem on
2967 Windows where the rotatelog processes created during preflight
2968 was not getting cleaned up properly.
2971 *) add "Request Phase Participation" info to mod_info
2974 *) Make first phase changes to the scoreboard data structures in
2975 preparation for the rewriting of the scoreboard per my posted
2976 design notes. [Paul J. Reder]
2978 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
2979 and apr-util, allow it to be overridden by the configure command-line
2980 (default="--silent") and introduce LT_LDFLAGS to replace what we were
2981 formerly abusing as LTFLAGS. [Roy Fielding]
2983 *) Clean up the reporting of incorrect closing container tags.
2984 [Barrie Slaymaker <barries@slaysys.com>]
2986 *) Simplify the configure process by moving all libtool stuff to APR
2987 and moving hints.m4 inline. [Roy Fielding]
2989 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
2990 of functions used by mod_proxy for export in the DLL
2991 [Ian Holsman <IanH@cnet.com>]
2993 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
2994 request body from its stdin but no reqest body is being written to
2995 the cgi. [Jeff Trawick]
2997 *) mod_log_config: %c connection status incorrectly logged
2998 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
3001 *) Get mod_cern_meta working under Windows
3004 *) Create Files, and thus MMAPs, out of the request pool, not the
3005 connection pool. This solves a small resource leak that had us
3006 not closing files until a connection was closed. In order to do
3007 this, at the end of the core_output_filter, we loop through the
3008 brigade and convert any data we have into a single HEAP bucket
3009 that we know will survive clearing the request_rec.
3010 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
3013 *) Completely revamp configure so that it preserves the standard make
3014 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
3015 the configure additions to EXTRA_* variables. Also, allow the user
3016 to specify NOTEST_* values for all of the above, which eliminates the
3017 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
3018 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
3019 avoid pointless duplications. Fix the order in which flags are given
3020 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
3021 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
3022 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
3023 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
3025 *) Get mod_tls to compile/work better on Windows. PR #7612
3026 [Bernhard Schrenk <b.schrenk@improx.com>]
3028 *) Fix shutdown/restart hangs in the threaded MPM.
3029 [Jeff Trawick, Greg Ames, Ryan Bloom]
3031 *) Removed the keptalive boolean from conn_rec because it is now only
3032 used by a single routine and can be replaced by a local variable.
3033 [Greg Stein, Ryan Bloom, Roy Fielding]
3035 *) Patch prefork to put enough of the signal processing back in so that
3036 signals are all handled properly now. The previous patch fixed the
3037 deadlock race condition, but broke the user directed signal handling.
3038 This fixes it to work the way it did before my previous prefork patch
3039 (primarily, SIGTERM is now working).
3041 *) Change how input filters decide how much data is returned to the
3042 higher filter. We used to use a field in the conn_rec, with this
3043 change, we use an argument to ap_get_brigade to determine how much
3044 data is retrieved. [Ryan Bloom]
3046 *) Fix seg fault at start-up introduced by Ryan's change to enable
3047 modules to specify their own logging tags. mod_log_config
3048 registers an optional function, ap_register_log_handler().
3049 ap_register_log_handler() was being called by http_core before
3050 the directive hash table was created. This patch creates the
3051 directive hash table before ap_register_log_handler() is
3052 registered as an optional function.
3053 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
3055 *) Add ap_set_int_slot() function
3056 [John K. Sterling <sterling@covalent.net>]
3058 *) Under certain circumstances, Apache did not supply the
3059 right response headers when requiring authentication.
3060 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
3061 (This is a port of the change that went into Apache 1.3.19.)
3063 *) Allow modules to specify their own logging tags. This basically
3064 allows a module to tell mod_log_config that when %x is encountered
3065 a specific function should be called. Currently, x can be any single
3066 character. It may be more useful to make this a string at some point.
3069 Changes with Apache 2.0.17
3071 *) If a higher-level filter handles the the byterange aspects of a
3072 request, then the byterange filter should not try to redo the
3073 work. The most common case of this happening, is a byterange
3074 request going through the proxy, and the origin server handles
3075 the byterange request. The proxy should ignore it.
3076 [Graham Leggett <minfrin@sharp.fm>]
3078 *) Changed the threaded mpm to have child_main join to each of the
3079 worker threads to make sure the kids are all gone before child_main
3080 exits after a signal (cleanup from perform_idle_server_maintenance).
3081 This is an extension of Ryans recent commit to make the child_main
3084 *) Add more options to the ap_mpm_query function. This also allows MPMs to
3085 report if their threads are dynamic or static. Finally, this also
3086 implements a new API, ap_show_mpm, which returns the MPM that was
3087 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
3089 *) Do not install the binaries from the support directory twice.
3090 [jun-ichiro hagino <itojun@iijlab.net>]
3092 *) The ap_f* functions should flush data to the filter that is passed
3093 in, not the the filter after the one passed in.
3094 [Ryan Morgan <rmorgan@covalent.net>]
3096 *) Make ab work again by changing its native types to apr types and formats.
3097 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3099 *) Move the byterange filter and all of the supporting functions back
3100 to the HTTP module. The byterange filter turned out to be very
3101 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
3103 *) Make clean, distclean, and extraclean consistently according to the
3104 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3106 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
3107 This may have been causing problems stopping processes in the threaded
3110 *) Fix content-length in mod_negotiation to a long int representation.
3113 *) Remove BindAddress from the default config file.
3114 [giles@nemeton.com.au]
3116 *) Allow module authors to add a module to their Apache build using
3117 --with-module, without re-running buildconf. The syntax is:
3118 --with-module=module_type:/path/to/module.c
3119 The configure script will copy the module.c file to
3120 modules/module_type, and it will be added to the relevant Makefiles.
3121 currently, this only works for static modules. [Ryan Bloom]
3123 *) Changes required to make prefork clean up idle children properly.
3124 There was a window during which a starting worker deadlocks when
3125 an idle cleanup arrives before it completes init. Apache then keeps
3126 trying to cleanup the same deadlocked worker forever (until higher
3127 pids come along, but it still will never reduce below the deadlocked
3128 pid). Thus the number of children would not reduce to the correct
3129 idle level. [Paul J. Reder]
3131 Changes with Apache 2.0.16
3133 *) Change the default installation directory to /usr/local/apache2,
3134 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
3136 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
3139 *) Get MaxRequestsPerChild working with the Windows MPM.
3142 *) Make generic hooks to work, with mod_generic_hook_import/export
3143 experimental modules. [Ben Laurie, Will Rowe]
3145 *) Fix segfaults for configuration file syntax errors such as
3146 "<Directory>" followed by "</Directory" and
3147 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
3149 *) Cleanup the --enable-layout option of configure. This makes
3150 us use a consistent location for the config.layout file, and it
3151 makes configure more portable.
3152 [jun-ichiro hagino <itojun@iijlab.net>]
3154 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
3155 csv/gnuplot format, rudimentary ssl support and various other tweaks
3156 to make results more true to what is measured. The upshot of this it
3157 turns out that 'ab' has often underreported the true performance of
3158 apache. Often by a order of magnitude :-) See talk/paper of Sander
3159 Temme at April ApacheCon 2001 for details.
3160 [Dirk-Willem van Gulik]
3162 *) Clean up mod_cgid's temporary request pool. Besides fixing a
3163 storage leak this ensures that some unnecessary pipes are closed.
3166 *) Performance: Add quick_handler hook. This hook is called at the
3167 very beginning of the request processing before location_walk,
3168 translate_name, etc. This hook is useful for URI keyed content
3169 caches like Mike Abbott's Quick Shortcut Cache.
3172 *) top_module global variable renamed to ap_top_module [Perl]
3174 *) Move ap_set_last_modified to the core. This is a potentially
3175 controversial change, because this is kind of HTTP specific. However
3176 many protocols should be able to take advantage of this kind of
3177 information. I expect that headers will need one more layer of
3178 indirection for multi-protocol work, but this is a small step in
3179 the right direction. [Ryan Bloom]
3181 *) Enable mod_status by default. This matches what Apache 1.3 does.
3184 *) Add a ScriptSock directive to the default config file. This is
3185 only enabled when mod_cgid is used.
3186 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3188 Changes with Apache 2.0.15
3190 *) Untangled the buildconf script and eliminated the need for build's
3191 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
3192 libtool muck that is now under srclib/apr/build. [Roy Fielding]
3194 *) Win32: Don't accept more connections than we have worker threads
3198 *) Fix bug in the Unix threaded.c MPM that allowed child processes
3199 to fork() new child processes.
3202 *) SECURITY: Fix a major security problem with double-reverse lookup
3203 checking. Previously, a client connecting over IPv4 would not be
3204 matched properly when the server had an IPv6 listening socket.
3205 PR #7407 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
3207 *) Change the way the beos MPM handles polling to allow it to stop and
3208 restart. Problem was the sockets being polled were being reset by
3209 the select call, so once it had accepted a connection it was no
3210 longer listening on the UDP socket we use for shutdown instructions.
3211 APR needs to be altered, patch on it's way. [David Reid]
3213 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
3214 on error exit from ap_getline(). Some other code got upset because
3215 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
3217 *) Handle ap_discard_request_body() being called more than once.
3218 [Greg Ames, Jeff Trawick]
3220 *) Get rid of an inadvertent close of file descriptor 2 in
3221 mod_mime_magic. [Greg Ames, Jeff Trawick]
3223 *) Add a hook, create_request. This hook allows modules to modify
3224 a request while it is being created. This hook is called for all
3225 request_rec's, main request, sub request, and internal redirect.
3226 When this hook is called, the the r->main, r->prev, r->next
3227 pointers have been set, so modules can determine what kind of
3228 request this is. [Ryan Bloom]
3230 *) Cleanup the build process a bit more. The Apache configure
3231 script no longer creates its own helper scripts, it just
3233 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
3235 *) Stop the forced downgrade of the connection to HTTP/1.0 for
3236 proxy requests. [Graham Leggett]
3238 *) Avoid using sscanf to determine the HTTP protocol number in
3239 the common case because sscanf is a performance hog. From
3240 Mike Abbot's Accelerating Apache patch number 6.
3241 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
3243 *) SECURITY: Fix a security exposure in mod_access. Previously when
3244 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
3245 were not evaluated properly (PR #7407). Also, add the ability to
3246 specify IPv6 address strings with optional prefix length on Allow
3247 and Deny. [Jeff Trawick]
3249 *) Enhance rotatelogs so that a UTC offset can be specified, and
3250 the logfile name can be formatted using strftime(3). (Brought
3251 forward from 1.3.) [Ken Coar]
3253 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
3254 DuplicateHandle on an IOCompletionPort (a practice which
3255 MS "discourages"). The new model does not rely on associating
3256 the completion port with the listening sockets, thus the
3257 completion port can be completely managed within the child
3258 process. A dedicated thread accepts connections off the network,
3259 then calls PostQueuedCompletionStatus() to wake up worker
3260 threads blocked on the completion port.
3263 *) Bring forward the --suexec-umask option which allows the
3264 builder to preset the umask for suexec processes. [Ken Coar]
3266 *) Add a -V flag to suexec, which causes it to display the
3267 compile-time settings with which it was built. (Only
3268 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
3270 *) Mod_include should always unset the content-length if the file is
3271 going to be passed through send_parsed_content. There is no to
3272 determine if the content will change before actually scanning the
3273 entire content. It is far safer to just remove the C-L as long
3274 as we are scanning it. [Ryan Bloom]
3276 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
3277 request and not Proxy-Authenticate.
3278 [Graham Leggett <minfrin@sharp.fm>]
3280 Changes with Apache 2.0.14
3282 *) Fix content-length computation. We ONLY compute a content-length if
3283 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
3284 or we already have all the data. [Ryan Bloom]
3286 *) Report unbounded containers in the config file. Previously, a typo
3287 in the </container> directive could result in the rest of the config
3288 file being silently ignored, with undesired defaults used.
3291 *) Make the old_write filter use the ap_f* functions for the buffering.
3294 *) Move more code from the http module into the core server. This
3295 is core code, basically the default handler, the default input
3296 and output filters, and all of the core configuration directives.
3297 All of this code is required in order for the server to work, with or
3298 without HTTP. The server is closer to working without the HTTP
3299 module, although there is still more to do. [Ryan Bloom]
3301 *) Fix a number of SGI compile warnings throughout the server. Fix some
3302 bad parameters to apr_bucket_read(). Fix a bad statement in
3303 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
3304 consistently; we were mixing apr_time_t and time_t in invalid ways
3305 before. In load_file(), call apr_dso_error() instead of
3306 apr_strerror() so that we get a more specific string on some platforms.
3307 PR #6980 [Jeff Trawick]
3309 *) Allow modules to query the MPM about it's execution profile. This
3310 query API can and should be extended in the future, but for now,
3311 max_daemons, and threading or forking is a very good start.
3312 [Jon Travis <jtravis@covalent.net>]
3314 *) Modify mod_include to send blocks of data no larger than 9k.
3315 Without this, mod_include will wait until the whole file is parsed,
3316 or the first tag is found to send any data to the client.
3317 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3319 *) Fix mod_info, so that <Directory> and <Location> directives are
3320 not displayed twice when displaying the current configuration.
3321 [Ryan Morgan <rmorgan@covalent.net>]
3323 *) Add config directives to override DEFAULT_ERROR_MSG and
3324 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
3325 [Dan Rench <drench@xnet.com>]
3327 *) Get mod_info building and loading on Win32. [William Rowe]
3329 *) Begin to move protocol independant functions out of mod_http. The goal
3330 is to have only functions that are HTTP specific in the http directory.
3333 Changes with Apache 2.0.13
3335 *) Don't assume that there will always be multiple calls to the byterange
3336 filter. It is possible that we will need to do byteranges with only
3337 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
3339 *) Move the error_bucket definition from the http module to the
3340 core server. Every protocol will need this ability, not just
3343 Changes with Apache 2.0.12
3345 *) Modify mod_file_cache to save pre-formatted strings for
3346 content-length and last-modified headers for performance.
3347 [Mike Abbot <mja@trudge.engr.sgi.com>]
3349 *) Namespace protect IOBUFSIZ since it is exposed in the API.
3350 [Jon Travis <jtravis@covalent.net>]
3352 *) Use "Basic" authentication instead of "basic" in ab, as the spec
3353 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
3355 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
3356 without ever filling it out. This fixes PR 7271.
3357 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
3358 Cliff Woolley <cliffwoolley@yahoo.com>]
3360 *) Add a couple of GCC attribute tags to printf style functions.
3361 [Jon Travis <jtravis@covalent.net>]
3363 *) Add the correct language tag for interoperation with the Taiwanese
3364 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
3366 *) Migrate the perchild MPM to use the new apr signal child, and
3367 APR thread functions. [Ryan Bloom]
3369 *) Close one copy of the CGI's stdout before creating the new process.
3370 The CGI will still have stdout, because we have already dup'ed it.
3371 This keeps Apache from waiting forever to send the results of a CGI
3372 process that has forked a long-lived child process.
3373 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3375 *) Remove the rest of the pthreads functions from the threaded MPM.
3376 This requires the APR support for a signal thread that was just
3379 *) Make mod_dir use a fixup for sending a redirect to the browser.
3380 Before this, we were using a handler, which doesn't make much
3381 sense, because the handler wasn't generating any data, it would
3382 either return a redirect error code, or DECLINED. This fits the
3383 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
3385 *) Make the threaded MPM use APR threads instead of pthreads.
3388 *) Get mod_tls to the point where it actually appears to work in all cases.
3391 *) implement --enable-modules and --enable-mods-shared for "all" and
3392 "most". [Greg Stein]
3394 *) Move the threaded MPM to use APR locks instead of pthread locks.
3397 *) Rename mpmt_pthread to threaded. This is more in line with the
3398 fact that mpmt_pthread shouldn't be using pthreads directly, and
3399 it is a smaller name that doesn't tie into anything.
3402 *) Rename the module structures so that the exported symbol matches
3403 the file name, and it is easier to automate the installation
3404 process (generating LoadModule directives from the module filenames).
3407 *) Remove the coalesce filter. With the ap_f* functions, this filter
3408 is no longer needed. [Ryan Bloom]
3410 Changes with Apache 2.0.11
3412 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
3413 added feature of allowing a uid/gid per child process. If no
3414 uid/gid is specified, then Perchild behaves exactly like dexter.
3417 *) Get perchild building again. [Ryan Bloom]
3419 *) Don't disable threads just because we are using the prefork MPM.
3420 If somebody wants to compile without threads, they must now add
3421 --disable-threads to the configure command line. [Ryan Bloom]
3423 *) Begin to move the calls to update_child_status into common code, so
3424 that each individual MPM does not need to update the scoreboard itself.
3427 *) Allow mod_tls to compile under Unix boxes where openssl has been
3428 installed to the system include files.
3429 [Gomez Henri <new-httpd@slib.fr>]
3431 *) Cleanup the mod_tls configure process. This should remove any need
3432 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
3433 configure doesn't check that yet. [Ryan Bloom]
3435 *) Add a very early prototype of SSL support (in mod_tls.c). It is
3436 vital that you read modules/tls/README before attempting to build
3439 *) Fix a potential seg fault on all platforms. David Reid fixed this
3440 on BEOS, but the problem could happen anywhere, so we don't want
3441 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
3443 *) Add new LogFormat directive, %D, to log time it takes to serve a
3444 request in microseconds. [Bill Stoddard]
3446 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
3447 SetOutputFilter. This corresponds nicely with the other Set
3448 directives, which operate on containers while the Add* directives
3449 tend to work directly on extensions. [Ryan Bloom]
3451 *) Cleanup the header handling a bit. This uses the apr_brigade_*
3452 functions for the buffering so that we don't need to compute
3453 the length of the headers before we actually create the header
3454 buffer. [Ryan Bloom]
3456 *) Allow filters to buffer data using the ap_f* functions. These have
3457 become macros that resolve directly to apr_brigade_*.
3460 *) Get the Unix MPM's to do a graceful restart again. If we are going
3461 to register a cleanup with ap_cleanup_scoreboard, then we have to
3462 kill the cleanup with the same function, and that function can't be
3463 static. [Ryan Bloom]
3465 *) Install all required header files. Without these, it was not
3466 possible to compile some modules outside of the server.
3469 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
3470 forward from 1.3 to 2.0, we missed a single line, which broke regex
3471 aliases. [Ryan Bloom]
3473 *) We have a poor abstraction in the protocol. This is a temporary
3474 hack to fix the bug, but it will need to be fixed for real. If
3475 we find an error while sending out a custom error response, we back
3476 up to the first non-OK request and send the data. Then, when we send
3477 the EOS from finalize_request_protocol, we go to the last request,
3478 to ensure that we aren't sending an EOS to a request that has already
3479 received one. Because the data is sent on a different request than
3480 the EOS, the error text never gets sent down the filter stack. This
3481 fixes the problem by finding the last request, and sending the data
3482 with that request. [Ryan Bloom]
3484 *) Make the server status page show the correct restart time, and
3485 thus the proper uptime. [Ryan Bloom]
3487 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
3488 should reduce the amount of duplicate code that is required to
3489 create CGI processes.
3490 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3492 *) ap_new_connection() closes the socket and returns NULL if a socket
3493 call fails. Usually this is due to a connection which has been
3494 reset. [Jeff Trawick]
3496 *) Move the Apache version information out of httpd.h and into release.h.
3497 This is in preparation for the first tag with the new tag and release
3498 system. [Ryan Bloom]
3500 *) Begin restructuring scoreboard code to enable adding back in
3501 the ability to use IPC other than shared memory.
3502 Get mod_status working on Windows again. [Bill Stoddard]
3504 *) Make mod_status work with 2.0. This will work for prefork,
3505 mpmt_pthread, and dexter. [Ryan Bloom]
3507 *) Correct a typo in httpd.conf.
3508 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
3510 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
3512 *) Get the correct IP address if ServerName isn't set and we can't
3513 find a fully-qualified domain name at startup.
3514 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
3516 *) Make mod_cgid work with SuExec. [Ryan Bloom]
3518 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
3519 'extra' stat's for user/group since they should never occur, and now
3520 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
3521 volumes. [William Rowe]
3523 *) Adopt apr features to simplify mod_includes. This changes the
3524 behavior of the USER_NAME variable, unknown uid's are now reported
3525 as USER_NAME="<unknown>" rather than the old user#000 result.
3526 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
3528 *) Adopt apr features for simplifing mod_userdir, and accept the new
3529 Win32/OS2 exceptions without hiccuping. [William Rowe]
3531 *) Replace configure --with-optim option by using and saving the
3532 environment variable OPTIM instead. This is needed because configure
3533 options do not support multiple flags separated by spaces.
3536 *) Fix some byterange handling. If we get a byte range that looks like
3537 "-999999" where that is past the end of the file, we should return
3538 a PARTIAL CONTENT status code, and return the whole file as one big
3539 byterange. This matches the 1.3 handling now. [Ryan Bloom]
3541 *) Make the error bucket a real meta-data bucket. This means that the
3542 bucket length is 0, and a read returns NULL data. If one of these
3543 buckets is passed down after the headers are sent, this data will
3544 just be ignored. [Greg Stein]
3546 *) The prefork MPM wasn't killing child processes correctly if a restart
3547 signal was received while the process was serving a request. The child
3548 process would become the equivalent of a second parent process. If
3549 we break out of the accept loop, then we need to do die after cleaning
3550 up after ourselves. [Ryan Bloom]
3552 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
3553 restarts. [Ryan Bloom]
3555 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
3556 the most optimal APR_FINFO_wanted bits. This spares Win32 from
3557 performing very expensive owner, group and permission lookups
3558 and allows the server to function until these apr_finfo_t fields
3559 are implemented under Win32. [William Rowe]
3561 *) Support for typedsafe optional functions - that is functions exported by
3562 optional modules, which, therefore, may or may not be present, depending
3563 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
3564 for sample code. [Ben Laurie]
3566 *) filters can now report an HTTP error to the server. This is done
3567 by sending a brigade where the first bucket is an error_bucket.
3568 This bucket is a simple bucket that stores an HTTP error and
3569 a string. Currently the string is not used, but it may be needed
3570 to output an error log. The http_header_filter will find this
3571 bucket, and output the error text, and then return
3572 AP_FILTER_ERROR, which informs the server that the error web page
3573 has already been sent. [Ryan Bloom]
3575 *) If we get an error, then we should remove all filters except for
3576 those critical to serving a web page. This fixes a bug, where
3577 error pages were going through the byterange filter, even though
3578 that made no sense. [Ryan Bloom]
3580 *) Relax the syntax checking of Host: headers in order to support
3581 iDNS. PR#6635 [Tony Finch]
3583 *) Cleanup the byterange filter to use the apr_brigade_partition
3584 and apr_bucket_copy functions. This removes a lot of very messy
3585 code, and hopefully makes this filter more stable.
3588 *) Remove AddModule and ClearModuleList directives. Both of these
3589 directives were used to ensure that modules could be enabled
3590 in the correct order. That requirement is now gone, because
3591 we use hooks to ensure that modules are in the correct order.
3594 *) When SuExec is specified, we need to add it to the list of
3595 targets to be built. If we don't, then any changes to the
3596 configuration won't affect SuExec, unless 'make suexec' is
3597 specifically run. [Ryan Bloom]
3599 *) Cleaned out open_file from mod_file_cache, as apr now accepts
3600 the APR_XTHREAD argument to open a file for consumption by
3601 parallel threads on win32. [William Rowe]
3603 *) Correct a bug in determining when we follow symlinks. The code
3604 expected a stat -1 result, not an apr_status_t positive error.
3605 Also check if the APR_FINFO_USER fields are valid before we
3606 follow the link. [William Rowe]
3608 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
3609 mpm_common.c. These functions are only valid on some platforms,
3610 so they should not be in the main-line code. [Ryan Bloom]
3612 *) Remove ap_chdir_file(). This function is not thread-safe,
3613 and nobody is currently using it. [Ryan Bloom]
3615 *) Do not try to run make depend if there are no .c files in the
3616 current directory, doing so makes `make depend` fail.
3619 *) Update highperformance.conf to work with either prefork or
3620 pthreads mpms. [Greg Ames]
3622 *) Stop checking to see if this is a pipelined request if we know
3623 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
3624 This keeps us from making an extra read call when serving a 1.0
3625 request. [Ryan Bloom and Greg Stein]
3627 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
3628 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
3629 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
3631 *) Fix the RFC number mentioned when complaining about a missing
3632 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
3634 *) Fix an endless loop in ab which occurred when ab was posting
3635 and the server dropped the connection unexpectedly.
3638 *) Fix a segfault while handling request bodies in ap_http_filter().
3639 This problem has been seen with mod_dav usage as well as with
3640 requests where the body was just being discarded. [Jeff Trawick]
3642 *) Some adjustment on the handling and automatic setting (via
3643 hints.m4) of various compilation flags (eg: CFLAGS). Also,
3644 add the capability to specify flags (NOTEST_CFLAGS and
3645 NOTEST_LDFLAGS) which are used to compile Apache, but
3646 not used during the configuration process. Useful for
3647 flags like "-Werror". [Jim Jagielski]
3649 *) Stop using environment variables to force debug mode or
3650 no detach. We now use the -D command line argument to
3651 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
3652 [Greg Stein, Ryan Bloom]
3654 *) Change handlers to use hooks. [Ben Laurie]
3656 *) Stop returning copies of filenames from both apr_file_t and
3657 apr_dir_t. We pstrdup the filenames that we store in the
3658 actual structures, so we don't need to pstrdup the strings again.
3661 *) mod_cgi: Fix some problems where the wrong error value was being
3662 traced. [Jeff Trawick]
3664 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
3667 *) Add generic hooks. [Ben Laurie]
3669 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
3671 *) Fix a segfault caused by mod_ext_filter when the external filter
3672 program does not exist. [Jeff Trawick]
3674 *) Fix an output truncation error when on an HTTP >= 1.0 request an
3675 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
3676 was served through mod_charset_lite (or anything else that would
3677 create a transient bucket in this size range). ap_bucket_make_heap()
3678 silently failed (fixed), transient_setaside() discovered it, but
3679 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
3681 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
3682 is that some browsers send extra lines at the end of POST requests, and
3683 we don't want to delay sending data back to the user just because the
3684 browser isn't well behaved. [Ryan Bloom]
3686 *) Get SuEXEC working again. We can't send absolute paths to suExec
3687 because it refuses to execute those programs. SuEXEC also wasn't
3688 always recognizing configuration changes made using the autoconf
3691 *) Allow the buildconf process to find the config.m4 files in the correct
3692 order. Basically, we can now name config.m4 files as config\d\d.m4,
3693 and we will sort them correctly when inserting them into the build
3694 process. [Ryan Bloom]
3696 *) Get mod_cgid to use apr calls for creating the actual CGI process.
3697 This also allows mod_cgid to use ap_os_create_priviledged_process,
3698 thus allowing for SuExec execution from mod_cgid. Currently, we do
3699 not support everything that standard SuExec supports, but at least
3700 it works minimally now. [Ryan Bloom]
3702 *) Allow SuExec to be configured from the ./configure command line.
3705 *) Update some of the docs in README and INSTALL to reflect some of
3706 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
3708 *) If we get EAGAIN returned from the call to apr_sendfile, then we
3709 need to call sendfile again. This gets us serving large files
3710 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
3712 *) Get the support programs building cleanly again.
3713 [Cliff Woolley <cliffwoolley@yahoo.com>]
3715 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
3716 current directory logic now backs up over bin/ to determine the
3717 server root from the Apache.exe path.
3719 *) Apache/Win32 now follows the standard conventions of mod_foo.so
3720 loadable modules, dynamic libs are all named libfoo.dll, and the
3721 makefile.win populates the include, lib and libexec directories.
3723 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
3724 Apache gets IPv6 listening sockets by default. Additionally, the
3725 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
3726 numeric address strings (e.g., "Listen [fe80::1]:8080").
3729 *) Modify the install directory layout. Modules are now installed in
3730 modules/. Shared libraries should be installed in libraries/, but
3731 we don't have any of those on Unix yet. All install directories
3732 are modifyable at configure time. [Ryan Bloom]
3734 *) Install all header files in the same directory on Unix. [Ryan Bloom]
3736 *) Get the functions in server/linked into the server, regardless of
3737 which modules linked into the server. This uses the same hack
3738 for Apache that we use for APR and apr-util to ensure all of the
3739 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
3740 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
3741 the scripts a bit easier.
3744 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
3745 on the query, and remove IPv4 dependencies. [Jeff Trawick]
3747 *) Get all of the auth modules to the point that they will install and
3748 be loadable into the server. Our new build/install mechanism expects
3749 that all modules will have a common name format. The auth modules
3750 didn't use that format, so we didn't install them properly.
3753 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
3754 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
3756 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
3758 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
3759 after the end of the response. [Ryan Bloom]
3761 *) Get byterange requests working with responses that do not have a
3762 content-length. Because of the way byterange requests work, we have to
3763 have all of the data before we can actually do the byterange, so we
3764 can compute the content-length in the byterange filter.
3767 *) Get exe CGI's working again on Windows.
3770 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
3771 they keep track of whether or not their post config hook has been
3772 called before. Instead of a static variable (which is replaced when
3773 the DSO is loaded a second time), use userdata in the process pool.
3776 Changes with Apache 2.0a9
3778 *) Win32 now requires perl to complete the final install step for users
3779 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
3780 and installs the conf, htdocs and htdocs/manual directories.
3783 *) Make mod_include use a hash table to associate directive tags with
3784 functions. This allows modules to implement their own SSI tags easily.
3785 The idea is simple enough, a module can insert it's own tag and function
3786 combination into a hash table provided by mod_include. While mod_include
3787 parses an SSI file, when it encounters a tag in the file, it does a
3788 hash lookup to find the function that implements that tag, and passes
3789 all of the relevant data to the function. That function is then
3790 responsible for processing the tag and handing the remaining data back
3791 to mod_include for further processing.
3792 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3794 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
3795 fewer parameters: the local and remote socket addresses were removed
3796 from the parameter list because all required information is available
3797 via the APR socket. [Jeff Trawick]
3799 *) Distribution directory structure reorganized to reflect a
3800 normal source distribution with external install targets.
3803 *) The MPMs that need multiple segments of shared memory now create
3804 two apr_shmem_t variables, one for each shared memory allocation.
3805 the problem is that we can't determine how much memory will be required
3806 for shared memory allocations once we try to allocate more than one
3807 variable. The MM code automatically aligns the shared memory allocations,
3808 so we end up needing to pad the amount of shared memory we want based
3809 on how many variables will be allocated out of the shared memory segment.
3810 It is just easier to create a second apr_shmem_t variable, and two
3811 shmem memory blocks.
3814 *) Cleanup the export list a bit. This creates a single unified list of
3815 functions exported by APR. The export list is generated at configure
3816 time, and that list is then used to generate the exports.c file.
3817 Because of the way the export list is generated, we only export those
3818 functions that are valid on the platform we are building on.
3821 *) Enable logging the cookie with mod_log_config
3822 [Sander van Zoest <sander@covalent.net>]
3824 *) Fix a segfault in mod_info when it reaches the end of the configuration.
3827 *) Added lib/aputil/ as a placeholder for utility functions which are not
3828 specific to the Apache HTTP Server (but do not make sense with APR).
3829 The first utility is "apu_dbm": a set of functions to work with DBM
3830 files. This first version can be compiled for SDBM or GDBM databases.
3833 *) Complete re-write of mod_include. This makes mod_include a filter that
3834 uses buckets directly. This has now served the FAQ correctly.
3835 [Paul Reder <rederpj@raleigh.ibm.com>]
3837 *) Allow modules to specify the first filter in a sub_request when
3838 making the sub_request. This keeps modules from having to change the
3839 output_filter immediately after creating the sub-request, and therefore
3840 skip the sub_req_output_filter. [Ryan Bloom]
3842 *) Update ab to accept URLs with IPv6 literal address strings (in the
3843 format described in RFC 2732), and to build Host header fields in
3844 the same format. This allows IPv6 literal address strings to be
3845 used with ab. This support has been tested against Apache 1.3 with
3846 the KAME patch, but Apache 2.0 does not yet work with this format
3847 of the Host header field. [Jeff Trawick]
3849 *) Accomodate an out-of-space condition in the piped logs and the
3850 rotatelogs.c code, and no longer churn log processes for this
3851 condition. [Victor J. Orlikowski]
3853 *) Add support for partial writes with apr_sendfile() to core_output_filter.
3856 Changes with Apache 2.0a8
3858 *) Add a directive to mod_mime so that filters can be associated with
3862 *) Get multi-views working again. We were setting the path_info
3863 field incorrectly if we couldn't find the specified file.
3866 *) Fix 304 processing. The core should never try to send the headers
3867 down the filter stack. Always, just setup the table in the request
3868 record, and let the header filter convert it to data that is ready
3872 *) More fixes for the proxy. There are still bugs in the proxy code,
3873 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
3877 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
3880 *) APR: Add new apr_getopt_long function to handle long options.
3881 [B. W. Fitzpatrick <fitz@red-bean.com>]
3883 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
3884 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
3885 hostname resolution/address string parsing and building
3886 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
3887 of one of the apr_sockaddr_t structures for a socket. Change
3888 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
3890 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
3891 I have proxied pages with it, cleanup will commence soon.
3894 *) Make the proxy work with filters. This isn't perfect, because we
3895 aren't dealing with the headers properly. [Ryan Bloom]
3897 *) Do not send a content-length iff the C-L is 0 and this is a head
3898 request. [Ryan Bloom]
3900 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
3901 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
3903 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
3905 *) Get the default_handler to stop trying to deal with HEAD requests.
3906 The idea is to let the content-length filter compute the C-L before
3907 we try to send the data. If we can get the C-L correctly, then we
3908 should send it in the HEAD response.
3911 *) The Header filter can now determine if a body should be sent based
3912 on r->header_only. The general idea of this is that if we delay
3913 deciding to send the body, then we might be able to compute the
3914 content-length correctly, which will help caching proxies to cache
3915 our data better. Any handler that doesn't want to try to compute
3916 the content-length can just send an EOS bucket without data and
3917 everything will just work.
3920 *) Add the referer to the error log if one is available.
3921 [Markus Gyger <mgyger@itr.ch>]
3923 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
3924 change, the root of the configuration tree has been exposed to modules
3926 [Ryan Morgan <rmorgan@covalent.net>]
3928 *) Get the core_output_filter to use the bucket interface directly.
3929 This keeps us from calling the content-length filter multiple times
3930 for a simple static request.
3933 *) We are sending the content-type correctly now.
3934 [Ryan Bloom and Will Rowe]
3936 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
3937 a bogus bytes-sent value when the only thing being sent was trailers
3938 and writev() returned an error (or EAGAIN). [Jeff Trawick]
3940 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
3941 hints file to determine which platforms define
3942 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
3945 *) APR: add apr_get_home_directory() [Jeff Trawick]
3947 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
3949 *) Not all platforms have INADDR_NONE defined by default. Apache
3950 used to make this check and define INADDR_NONE if appropriate,
3951 but APR needs the check too, and I suspect other applications will
3952 as well. APR now defines APR_INADDR_NONE, which is always a valid
3953 value on all platforms.
3954 [Branko Èibej <brane@xbc.nu>]
3956 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
3957 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
3959 *) Relax the syntax checking of Host: headers in order to support
3960 iDNS. PR#6635 [Tony Finch]
3962 *) When reading from file buckets we convert to an MMAP if it makes
3963 sense. This also simplifies the default handler because the
3964 default handler no longer needs to try to create MMAPs.
3967 *) BUFF has been removed from the main server. The BUFF code will remain
3968 in the code until it has been purged from the proxy module as well.
3971 *) Byteranges have been completely re-written to be a filter. This
3972 has been tested, and I believe it is working correctly, but it could
3973 doesn't work for the Adobe Acrobat plug-in. The output almost matches
3974 the output from 1.3, the only difference being that 1.3 includes
3975 a content-length in the response, and this does not.
3978 *) APR read/write functions and bucket read functions now operate
3979 on unsigned integers, instead of signed ones. It doesn't make
3980 any sense to use signed ints, because we return the error codes,
3981 so if we have an error we should report 0 bytes read or written.
3984 *) Always compute the content length, whether it is sent or not.
3985 The reason for this, is that it allows us to correctly report
3986 the bytes_sent when logging the request. This also simplifies
3987 content-length filter a bit, and fixes the actual byte-reporing
3988 code in mod_log_config.c
3991 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
3992 it says, because it was only used by EOS and FLUSH buckets. Since
3993 neither of those are required at the end of a brigade, this was
3994 really signifying FLUSH_THE_DATA, but that can be determined better
3995 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
3996 buckets now return a length of 0, which is actually the amount of data
3997 read, so they make more sense.
4000 *) Allow the core_output_filter to save some data past the end of a
4001 request. If we get an EOS bucket, we only send the data if it
4002 makes sense to send it. This allows us to pipeline request
4003 responses. As a part of this, we also need to allocate mmap
4004 buckets out of the connection pool, not the request pool. This
4005 allows the mmap to outlive the request.
4008 *) Make blocking and non-blocking bucket reads work correctly for
4009 sockets and pipes. These are the only bucket types that should
4010 have non-blocking reads, because the other bucket types should
4011 ALWAYS be able to return something immediately.
4014 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
4015 server, but use Ctrl+Break to initiate a graceful restart
4016 instead of duplicating behavior. [John Sterling]
4018 *) Patch mod_autoindex to set the Last-Modified header based on
4019 the directory's mtime, and add the ETag header. [William Rowe]
4021 *) Merge the 1.3 patch to add support for logging query string in
4022 such a way that "%m %U%q %H" is the same as "%r".
4025 *) Port three log methods from mod_log_config 1.3 to 2.0:
4026 CLF compliant '-' byte count, method and protocol.
4029 *) Add a new LogFormat directive, %c, that will log connection
4030 status at the end of the response as follows:
4031 'X' - connection aborted before the response completed.
4032 '+' - connection may be kept-alive by the server.
4033 '-' - connection will be closed by the server.
4036 *) Expand APR for WinNT to fully accept and return utf-8 encoded
4037 Unicode file names and paths for Win32, and tag the Content-Type
4038 from mod_autoindex to reflect that charset if the the feature
4039 macro APR_HAS_UNICODE_FS is true. [William Rowe]
4041 *) Compute the content length (and add appropriate header field) for
4042 the response when no content length is available and we can't use
4043 chunked encoding. [Jeff Trawick]
4045 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
4046 so that content input filters get dechunked data when using
4047 the default handler. Also removed REQUEST_CHUNKED_PASS.
4050 *) Add mod_ext_filter as an experimental module. This module allows
4051 the administrator to use external programs as filters. Currently,
4052 only filtering of output is supported. [Jeff Trawick]
4054 *) Most Apache functions work on EBCDIC machines again, as protocol
4055 data is now translated (again). [Jeff Trawick]
4057 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
4058 the EBCDIC support. They are noops on ASCII machines, so this
4059 type of translation doesn't have to be surrounded by #ifdef
4060 CHARSET_EBCDIC. [Jeff Trawick]
4062 *) Fix mod_include. tag commands work again, and the server will
4063 send the FAQ again. This also allows mod_include to set aside
4064 buckets that include partial buckets.
4065 [Ryan Bloom and David Reid]
4067 *) Add suexec support back. [Manoj Kasichainula]
4069 *) Lingering close now uses the socket directly instead of using
4070 BUFF. This has been tested, but since all we can tell is that it
4071 doesn't fail, this needs to be really hacked on.
4074 *) Allow filters to modify headers and have those headers be sent to
4075 the client. The idea is that we have an http_header filter that
4076 actually sends the headers to the network. This removes the need
4077 for the BUFF to send headers.
4080 *) Charset translation: mod_charset_lite handles translation of
4081 request bodies. Get rid of the xlate version of ap_md5_digest()
4082 since we don't compute digests of filtered (e.g., translated)
4083 response bodies this way anymore. (Note that we don't do it at
4084 all at the present; somebody needs to write a filter to do so.)
4087 *) Input filters and ap_get_brigade() now have a input mode parameter
4088 (blocking, non-blocking, peek) instead of a length parameter.
4091 *) Update the mime.types file to the registered media types as
4092 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
4095 *) Namespace protect some macros declared in ap_config.h
4098 *) Support HTTP header line folding with input filtering.
4101 *) Mod_include works again. This should still be re-written, but at
4102 least now we can serve an SHTML page again.
4105 *) Begin to remove BUFF from the core. Currently, we keep a pointer
4106 to both the BUFF and the socket in the conn_rec. Functions that
4107 want to use the BUFF can, functions that want to use the socket,
4108 can. They point to the same place.
4111 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
4112 [Tomas "Ögren" <stric@ing.umu.se>]
4114 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
4115 associated pool goes away. (APR pipes on OS/2 were already had this
4116 logic.) This resolvs a fatal file descriptor leak with CGIs.
4119 *) The final line of the config file was not being read if there was
4120 no \n at the end of it. This was caused by apr_fgets returning
4121 APR_EOF even though we had read valid data. This is solved by
4122 making cfg_getline check the buff that was returned from apr_fgets.
4123 If apr_fgets return APR_EOF, but there was data in the buf, then we
4124 return the buf, otherwise we return NULL.
4127 *) Piped logs work again in the 2.0 series.
4130 *) Restore functionality broken by the mod_rewrite security fix:
4131 rewrite map lookup keys and default values are now expanded
4132 so that the lookup can depend on the requested URI etc.
4133 PR #6671 [Tony Finch]
4135 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
4136 security bug in some mass virtual hosting configurations
4137 that can allow a remote attacker to retrieve some files
4138 on the system that should be inaccessible. [Tony Finch]
4140 *) Add a pool bucket type. This bucket is used for data allocated out
4141 of a pool. If the pool is cleaned before the bucket is destroyed, then
4142 the data is converted to a heap bucket, allowing it to survive the
4146 *) Add a flush bucket. This allows modules to signal that the filters
4147 should all flush whatever data they currently have. There is no way
4148 to actually force them to do this, so if a filter ignores this bucket,
4149 that's life, but at least we can try with this.
4152 *) Add an output filter for sub-requests. This filter just strips the
4153 EOS bucket so that we don't confuse the main request's core output
4154 filter by sending multiple EOS buckets. This change also makes sub
4155 requests start to send EOS buckets when they are finished.
4158 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
4159 makes ap_bucket_destroy a return void, which is okay because it
4160 used to always return APR_SUCCESS, and nobody ever checked its
4161 return value anyway.
4162 [Cliff Woolley <cliffwoolley@yahoo.com>]
4164 *) Remove the index into the bucket-type table from the buckets
4165 structure. This has now been replaced with a pointer to the
4166 bucket_type. Also add some macros to test the bucket-type.
4169 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
4170 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
4171 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
4172 All _VAR_ flavors changes to _DATA to be absolutely clear.
4175 *) Add support for /, //, //servername and //server/sharename
4176 parsing of <Directory> blocks under Win32 and OS2.
4177 [Tim Costello, William Rowe, Brian Harvard]
4179 *) Remove the function pointers from the ap_bucket type. They have been
4180 replaced with a global table. Modules are allowed to register bucket
4181 types and use then use those buckets.
4184 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
4185 once we finish writing the request body to the cgi child process;
4186 otherwise, the client doesn't hit EOF on stdin. Small request bodies
4187 worked without this change (for reasons I don't understand), but large
4188 ones didn't. [Jeff Trawick]
4190 *) Remove file bucket specific information from the ap_bucket type.
4191 This has been moved to a file_bucket specific type that hangs off
4192 the data pointer in the ap_bucket type.
4195 *) Input filtering now has a third argument. This is the amount of data
4196 to read from lower filters. This argument can be -1, 0, or a positive
4197 number. -1 means give me all the data you have, I'll deal with it and
4198 let you know if I need more. 0 means give me one line and one line
4199 only. A positive number means I want no more than this much data.
4201 Currently, only 0 and a positive number are implemented. This allows
4202 us to remove the remaining field from the conn_rec structure, which
4206 *) Big cleanup of the input filtering. The goal is that http_filter
4207 understands two conditions, headers and body. It knows where it is
4208 based on c->remaining. If c->remaining is 0, then we are in headers,
4209 and http_filter returns a line at a time. If it is not 0, then we are
4210 in body, and http_filter returns raw data, but only up to c->remaining
4211 bytes. It can return less, but never more.
4212 [Greg Ames, Ryan Bloom, Jeff Trawick]
4214 *) mod_cgi: Write all of the request body to the child, not just what
4215 the kernel would accept on the first write. [Jeff Trawick]
4217 *) Back out the change that moved the brigade from the core_output_filters
4218 ctx to the conn_rec. Since all requests over a given connection
4219 go through the same core_output_filter, the ctx pointer has the
4223 *) Fix another bug in the send_the_file() read/write loop. A partial
4224 send by apr_send would cause unsent data in the read buffer to
4225 get clobbered. Complete making send_the_file handle partial
4226 writes to the network.
4229 *) Fix a couple of type fixes to allow compilation on AIX again
4230 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
4232 *) Fix bug in send_the_file() which causes offset to be ignored
4233 if there are no headers to send.
4236 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
4237 filter. Useful for supporting Windows 9* with a binary
4238 compiled on Windows NT.
4241 Changes with Apache 2.0a7
4243 *) Reimplement core_output_filter to buffer/save bucket brigades
4244 across multiple calls to the core_filter. The brigade will be
4245 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
4246 thresholds are hit or the EOS bucket is received.
4249 *) Create experimental filter (buffer_filter) that coalesces bytes
4250 into one large buffer before invoking the next filter in the
4251 chain. This filter is particularly useful with the current
4252 implementation of mod_autoindex when it inserted above the
4253 chunk_filter. mod_autoindex generates a lot of brigades that
4254 containing buckets holding just a few bytes each. The
4255 buffer_filter coalesces these buckets into a single large bucket.
4258 *) Add apr_sendfile() support into the core_output_filter.
4261 *) Add apr_sendv() support into the core_output_filter.
4264 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
4265 [Mike Abbott <mja@sgi.com>]
4267 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
4268 make much sense, because Apache uses buckets instead of BUFFs now.
4271 *) send_the_file now falls back to a read/write loop on platforms that
4272 do not have sendfile.
4273 [Ryan Bloom and Brian Havard]
4275 *) Install apachectl correctly, and substitute the proper values so
4276 that it works again. [Ryan Bloom]
4278 *) Better(??) handle platforms that lack sendfile().
4281 *) APR now has UUID generation/formatting/parsing support.
4284 *) Begin the http_filter. This is an input filter that understands
4285 the absolute basic amount required to parse an HTTP Request. The
4286 goal is to be able to split headers from request body before passing
4287 the data back to the other filters.
4290 *) Bring forward from 1.3.13 the config directory implementation
4293 *) install apxs if it is created
4296 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
4297 conversions. [William Rowe]
4299 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
4300 ap_add_output_filter(). [Jeff Trawick]
4302 *) Multiple build and configuration fixes
4305 -add datadir and localstatedir substitutions
4307 -fix logfilename misspelling
4308 -fix evaluation of installation dir variables and
4309 -replace $foobar by $(foobar) to be usefull in the makefile
4313 -add rules for cross-compiling in rules.mk. Okay, rule to check for
4314 $CC_FOR_BUILD is still missing
4315 -use CHECK_TOOL instead of CHECK_PROG for ranlib
4316 -add missing "AR=@AR@" to severaly Makefile.in's
4317 -cache result for "struct rlimit"
4318 -compile all helper programs with native and cross compiler
4319 and use the native version to generate header file
4320 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
4322 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
4324 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
4326 *) Fix a bug where a client which only sends \n to delimit header
4327 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
4328 message. Start working on ebcdic co-existance with input
4330 [William Rowe, Greg Ames]
4332 *) If mod_so is enabled in the server always create libexec, even
4333 if there are no modules installed in this directory. This is a
4334 requirement for APXS to work correctly.
4337 *) Connection oriented output filters are now stored in the
4338 conn_rec instead of the request_rec. This allows us to add the
4339 output filter in the pre-connection phase instead of the
4340 post_read_request phase, which keeps us from trying to write an
4341 error page before we have a filter to write to the network.
4342 [Ryan Bloom, Jeff Trawick, and Greg Ames]
4344 *) Cleaning up an mmap bucket no longer deletes the mmap. An
4345 mmap can be used across multiple buckets (default_handler with
4346 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
4347 the mmap itself can't be associated with the bucket.
4350 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
4353 *) Radical surgery to improve mod_isapi support under Win32.
4354 Includes a number of newer ServerSupportFunction calls, support
4355 for ReadClient (in order to retrieve POSTs greater than 48KB),
4356 and general bug fixes to more reliably load ISAPI .dll's and
4357 prevent leaking handle resources. Note: There are still
4358 discrepancies between IIS's and Apache's ServerVariables, and
4359 async calls are still not supported. Additional warnings are
4360 logged to facilitate debugging of unsupported ISAPI calls.
4363 *) Add input filtering to Apache. The basic idea for the input
4364 filters is the same as the ideas for output filters. The biggest
4365 difference is that instead of calling ap_pass_brigade, ap_get_brigade
4366 should be called, and the order of execution for the filter itself is
4367 different. When writing an output filter, a brigade is passed in,
4368 and filters operate directly on that brigade, when done, they call
4369 ap_pass_brigade. Input filters are the exact opposite. Because input
4370 is not a push operation, filters first call ap_get_brigade. When this
4371 function returns, the input filter will be left with a valid brigade.
4372 The input filter should then operate on the brigade, and return.
4375 *) Fix building on BSD/OS using its native make. The build system
4376 falls back to the BSD .include directive on that host platform.
4379 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
4380 SHA1 and plaintext password encodings. Make feature tests a
4381 bit more flexible. [William Rowe]
4383 *) Charset translation: mod_charset_lite handles output content
4384 translation in a filter. mod_charset_lite no longer ignores
4385 subrequests. A bunch of cruft related to BUFF's support for
4386 translating request and response bodies was removed.
4389 *) Move the addition of the CORE filter to the post_read_request
4390 hook in http_core.c. This removes the need to add the filter in
4391 multiple places and allows for an SSL module to be added much
4392 simpler. [Ryan Bloom]
4394 *) SECURITY: CVE-2000-0913 (cve.mitre.org)
4395 Fix a security problem that affects certain configurations of
4396 mod_rewrite. If the result of a RewriteRule is a filename that
4397 contains expansion specifiers, especially regexp backreferences
4398 $0..$9 and %0..%9, then it may be possible for an attacker to
4399 access any file on the web server. [Tony Finch]
4401 *) Fix a bug where errors that are detected during early request parsing
4402 don't produce visible HTTP error messages at the browser, because
4403 the core_filter wasn't present. [Greg Ames]
4405 *) Provide apr_socklen_t as a portability aid.
4406 [Victor J. Orlikowski]
4408 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
4409 as well as a comment arg to the add, adduser and update cmds.
4410 update allows the user to clear or preserve pw/groups/comment.
4411 Fixed a bug in dbmmanage that prevented the check option from
4412 parsing a password followed by :group... text. Corrected the
4413 seed calcualation for Win32 systems, and added -lsdbm support.
4416 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
4419 *) Avoid a segfault when parsing .htaccess files. An
4420 uninitialized tree pointer was passed to ap_build_config().
4423 *) Change the way that inet_addr & inet_network are checked for
4424 in APR's configure process to allow BeOS BONE to correctly
4425 find them. With this change BeOS BONE now builds from source
4426 with no problems. [David Reid]
4428 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
4429 the end of the parameters to execve() was stored in the wrong
4430 location, overlaying the storage beyond the newargs[] array and
4431 also passing uninitialized storage to execve(), which would
4432 sometimes fail with EFAULT. [Jeff Trawick]
4434 *) Fix a bug parsing configuration file containers. With a sequence
4435 like this in the config file
4437 <IfModule mod_kilroy.c>
4440 <IfModule mod_lovejoy.c>
4445 the second container would be terminated at the blank line due to
4446 sediment in the buffer from reading the prior </IfModule> and an
4447 error message would be generated for the real </IfModule> for the
4448 second container. Also due to this problem, any two characters
4449 could be used for "</" in the close of a container.
4452 *) ap_add_filter prototype changed to remove the ctx pointer. The
4453 pointer still remains in the filter structure, but it can not be
4454 a part of the ap_add_filter prototype. The reason is that when
4455 the core uses AddFilter to add a filter to the stack it doesn't
4456 know how to allocate the ctx pointer, or even how much memory should
4457 be allocated. The filters will have to be responsible for allocating
4458 the ctx memory when they need it.
4461 *) Add an AddFilter directive. This directive takes a list of filters
4462 that should be activated for the requested resource.
4465 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
4466 some other platforms). [Jeff Trawick]
4468 *) Modify mod_include to be a filter. Currently, it has only been tested
4469 on actual files, but it should work for CGI scripts too.
4472 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
4473 writes. apr_flush() for Unix: handle interrupted writes.
4476 *) NameVirtualHost can now take "*" as an argument instead of
4477 an IP address. This allows you to create a purely name-based
4478 virtual hosting server that does not have any IP addresses in
4479 the configuration file and which ignores the local address
4480 of any connections. PR #5595, PR #4455 [Tony Finch]
4482 *) Fix some compile warnings in mod_mmap_static.c
4483 [Mike Abbott <mja@sgi.com>]
4485 *) Fix chunking problem with CGI scripts. The general problem was that
4486 the CGI modules were adding an EOS bucket and then the core added an
4487 EOS bucket. The chunking filter finalizes the chunked response when it
4488 encounters an EOS bucket. Because two EOS buckets were sent, we
4489 finalized the response twice. The fix is to make sure we only send one
4490 EOS, by utilizing a flag in the request_rec.
4493 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
4494 and Win32. Previously, the first read from an apr_file_t set up via
4495 apr_put_os_file() would return a '\0'. [Jeff Trawick]
4497 *) Mod_cgid now creates a single element bucket brigade, with a pipe
4498 bucket, instead of using BUFF's and ap_r*.
4501 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
4502 [Mike Abbott <mja@sgi.com>]
4504 *) Remove ap_bopenf from buff code. This required modifying the file_cache
4505 code to use APR file's directly instead of going through BUFFs.
4508 *) Fix compile break on some platforms for mod_mime_magic.c
4509 [John K. Sterling <sterling@covalent.net>]
4511 *) Fix merging of AddDefaultCharset directive.
4512 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
4514 *) Minor revamp of the rlimit sections of code. We now test
4515 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
4516 is now "available" even if the platform doesn't support
4517 the rlimit family (it's just a noop though). [Jim Jagielski]
4519 *) Migrate the pre-selection of which MPM to use for specific
4520 platforms to hints.m4, which contains (or should contain)
4521 all platform specific "hints". [Jim Jagielski]
4523 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
4526 *) Add tables with non-string/binary values to APR.
4529 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
4532 *) Update PCRE to version 3.2. [Ryan Bloom]
4534 *) Change the way buckets' destroy functions are called so that
4535 they can be more directly used when changing the type of a
4536 bucket in place. [Tony Finch]
4538 *) Add generic support for reference-counting the resources used by
4539 buckets, and alter the HEAP and MMAP buckets to use it. Change
4540 the way buckets are initialised to support changing the type of
4541 buckets in place, and use it when setting aside TRANSIENT buckets.
4542 Change the implementation of TRANSIENT buckets so that it can be
4543 mostly shared with IMMORTAL buckets, which are now implemented.
4546 Changes with Apache 2.0a6
4548 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
4550 *) Add a chunking filter to Apache. This brings us one step closer
4551 to removing BUFF. [Ryan Bloom]
4553 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
4554 added to the stack is the last filter to be called. [Ryan Bloom]
4556 *) Apache 2.0 has been completely documented using Scandoc. The
4557 docs can be generated by running 'make docs'. [Ryan Bloom]
4559 *) Add filtered I/O to Apache. This is based on bucket brigades,
4560 Currently the buckets still use BUFF under the covers, but that
4561 should change quickly. The only currently written filter is the
4562 core filter which just calls ap_bwrite. [The Apache Group]
4564 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
4565 built with thread support. [Jeff Trawick]
4567 *) Abort configuration if --with-layout was specified and there's
4568 no layout definition file. [Ken Coar]
4570 *) Add support for '--with-port=n' option to configure. [Ken Coar]
4572 *) Add support for extension methods for the Allow response header
4573 field, and an API routine for accessing r->allowed and the
4574 list of extension methods in a unified manner. [Ken Coar]
4576 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
4577 [Rob Simonson <simo@us.ibm.com>]
4579 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
4580 APACHE_XLATE builds. [Jeff Trawick]
4582 *) A configuration file parsing problem was fixed. When the
4583 configuration file started with an IfModule/IfDefine container,
4584 only the last statement in the container would be retained.
4587 Changes with Apache 2.0a5
4589 *) Perchild is serving pages after passing them to different child
4590 processes. There are still a lot of bugs, but this does work. I
4591 have made requests against the same installation of Apache, and had
4592 different servers use different user IDs to serve the responses.
4593 This change moves to using socketpair instead of an AF_UNIX socket.
4596 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
4597 It can't seem to pass between child processes yet, but I think we
4598 are closer now than before. This moves us back to using Unix
4599 Domain Sockets. [Ryan Bloom]
4601 *) libapr functions and types renamed with apr_ prefix.
4602 #include "apr_compat.h" for 1.3.x backwards compat
4605 *) Fix problems with APR sockaddr handling on Win32. It didn't always
4606 return the right information on the local socket address.
4607 [Gregory Nicholls <gnicholls@level8.com>]
4609 *) ap_recv() on Win32: Set bytes-read to 0 on error.
4610 [Gregory Nicholls <gnicholls@level8.com>]
4612 *) Add an option to not detach from the controlling terminal without
4613 going into single process mode. This allows for much easier
4614 debugging of the process startup code. [Ryan Bloom]
4616 *) ab: don't use perror() to report the failure of an APR function.
4619 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
4620 scoreboard on graceful restarts.
4623 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
4624 An invalid ap_proc_t was passed to ap_create_process().
4627 *) Allow modules to register filters. Those filters are still
4628 never called, but this is a step in the right direction.
4629 [Ryan Bloom and Greg Stein]
4631 *) Register the mod_cgid daemon process for cleanup so that it is
4632 killed at termination if it does not die when the parent gets
4633 SIGTERM. This change is to fix occasional problems where the
4634 process stays around. Bugs in similar logic in mod_rewrite and
4635 mod_include were also fixed. [Jeff Trawick]
4637 *) Fix a bug in the time handling. Basically, we were imploding a time
4638 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
4639 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
4640 uses those two fields to adjust the time value. Because of the HTTP
4641 spec, both of those values can be zero'ed out safely. This fixes
4642 the bug correctly. [Ryan Bloom]
4644 *) Fix a couple of place in the Windows code where the wrong error
4645 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
4647 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
4649 *) Added the APR_EOL_STR macro for platform dependent differences in
4650 logfiles and other raw text (such as all APR files). Fixes logfiles
4651 not terminated with cr/lf sequences in Win32. [William Rowe]
4653 *) Move all strings functions in APR to src/lib/apr/strings and create
4654 apr_strings.h for the prototypes. [Ryan Bloom]
4656 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
4657 to repeat the syscall until we stop getting EINTR. I noticed a
4658 related problem at termination (SIGTERM) on FreeBSD when using
4659 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
4660 implementation work properly with child init. Previously, ap_lock()
4661 was essentially a no-op because all children were using different
4662 locks and thus nobody ever blocked. [Jeff Trawick]
4664 *) The htdocs/ tree has been moved out of the CVS source tree into
4665 a separate area for easier development. This has NO EFFECT on
4666 end-users or Apache installations. [Ken Coar]
4668 *) Integrate the mod_dav module for WebDAV protocol handling. This
4669 adds the dav and dav_fs modules, the SDBM library, and additional
4670 XML handling utilities. [Greg Stein]
4672 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
4675 *) Update the lib/expat-lite/ library (bring forward changes from
4676 the Apache 1.3 repository). [Greg Stein]
4678 *) If sizeof(long long) == sizeof(long), then prefer long in APR
4679 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
4681 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
4682 machines where sendfile is detected, but nobody has written ap_sendfile.
4683 [Dave Hill <ddhill@zk3.dec.com>]
4685 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
4687 *) ab would start up more connections than needed, then quit when the
4688 desired number were finished. Also fixed a logic error involving
4689 ab keepalives. [Victor J. Orlikowski]
4691 *) WinNT: Implement non-blocking pipes with timeouts to communicate
4692 with CGIs. Apache 2.0a4 had non-blocking pipes but without
4693 timeouts (i.e, if a timeout was specified, the pipe reverted to
4694 a full blocking pipe). Now the behaviour is more in line with
4695 Unix non-blocking pipes.
4698 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
4699 cache open file handles along with accept socket reuse enables
4700 Apache 2.0 to serve non-keepalive requests for static files at
4701 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
4702 and Apache 2.0 will serve almost 1200 rps on my system).
4705 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
4706 supports two config directives, mmapfile (same behavious as
4707 mod_mmap_static) and cachefile. Use the cachefile directive
4708 to cache open file handles. This directive only works on systems
4709 that have implemented the ap_sendfile API. cachefile works today
4710 on Windows NT, but has not been tested on any flavors of Unix.
4713 *) Cleanup the configuration. With the last few changes the
4714 configuration process automatically:
4715 inherits information about how to build from APR. Allowing
4716 APR to inform Apache that it should or should not use -ldl
4718 Detects which mod_cgi should be used mod_cgi or mod_cgid,
4719 based on the threading model
4721 Apache calls APR's configure process before finishing it's
4722 configuration processing, allowing for more information flow
4727 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
4728 with non-zero argument makes the socket non-blocking. BeOS and
4729 OS/2 already worked this way. [Jeff Trawick]
4731 *) ap_close() now calls ap_flush() for buffered files, so write
4732 operations work a whole lot better on buffered files.
4735 *) Fix error messages issued from MPMs which explain where to change
4736 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
4739 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
4740 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
4741 now the way that the blocking state of a pipe is manipulated.
4742 ap_block_pipe() is gone. [Jeff Trawick]
4744 *) Correct the problem where the only local host name that the IP stack
4745 can discover are 'undotted' private names. If no fully qualified
4746 domain name can be identified, the default ServerName will be set to
4747 the machine's IP address string. A warning is always provided if the
4748 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
4750 *) Repair problems with config file processing which caused segfault
4751 at init when virtual hosts were defined and which caused ServerName to
4752 be ignored when there was no valid DNS setup. [Jeff Trawick]
4754 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
4756 *) Add ap_sendfile implementation for AIX
4757 [Victor J. Orlikowski]
4759 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
4760 apr_network_io.h, and apr_thread_proc.h.
4761 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
4763 *) Bring the allocation and pool debugging code back into a working
4764 state. This will need to be tested as so far it's only been used on
4767 *) Change configuration command setup to be properly typesafe when in
4768 maintainer mode. Note that this requires a compiler that can initialise
4769 unions. [Ben Laurie]
4771 *) Turn on buffering for config file reads. Part of this was to
4772 repair buffered I/O support in Unix and implement buffered
4773 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
4775 *) Win32: Fix problem where UTC offset was not being set correctly
4776 in the access log. Problem reported on news group by Jerry Baker.
4779 *) Fix segfault when reporting this type of syntax error:
4780 "</container> without matching <container> section", where
4781 container is VirtualHost or Directory or whatever.
4784 *) SECURITY: CAN-2000-1204 (cve.mitre.org)
4785 Prevent the source code for CGIs from being revealed when
4786 using mod_vhost_alias and the CGI directory is under the document root
4787 and a user makes a request like http://www.example.com//cgi-bin/cgi
4788 as reported in <news:960999105.344321@ernani.logica.co.uk>
4791 *) Add support for the new Beos NetwOrking Environment (BONE)
4794 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
4795 final input char is incomplete; ap_bwrite_xlate() now handles
4796 incomplete final input chars. [Jeff Trawick]
4798 *) Yet another update to saferead/halfduplex stuff -- need to ensure
4799 that a bhalfduplex call occurs before logging or else DNS and
4800 such can delay the last packet of the response. [Dean Gaudet]
4802 *) Some syscall reduction in APR on unix -- don't seek when setting
4803 up an mmap; and don't fcntl() more than once per socket.
4806 *) When mod_cgid is started as root, the cgi daemon now switches
4807 to the configured User/Group (like other httpd processes)
4808 instead of continuing as root. [Jeff Trawick]
4810 *) The prefork MPM now uses an APR lock for the accept() mutex.
4811 It has not been getting a lock at all recently. httpd -V now
4812 displays APR's selection of the lock mechanism instead of the
4813 symbols previously respected by prefork. [Jeff Trawick]
4815 *) Change the mmap() feature test to check only for existence.
4816 The previous check required features not used by Apache.
4819 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
4820 sometimes mangled. The len parm to accept() was not
4821 initialized, leading sometimes to an endless loop of failed
4822 accept() calls on OS/390 and anywhere else that failed the call
4823 if the len was negative. Use <sys/un.h> for struct sockaddr_un
4824 instead of declaring it ourselves to fix a compilation problem
4825 on Solaris. [Jeff Trawick]
4827 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
4829 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
4831 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
4833 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
4834 initialization if ALLOC_DEBUG is defined; no known symptom
4835 otherwise. [Jeff Trawick]
4837 *) Fix typo in configure script when checking for mod_so. bash
4838 doesn't seem to have a problem but /bin/sh on Solaris does.
4839 Symptom: "./configure: test: unknown operator =="
4842 *) Rebind the Win32 NT and 9x services control into the MPM.
4843 All console, WinNT SCM and Win9x pseudo-service control code is
4844 now wrapped within the WinNT MPM.
4847 *) Make a copy of getenv("PATH") before storing for later use. Some
4848 getenv() implementations use the same storage for successive calls.
4849 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
4851 *) Server Tokens work in 2.0 again. This also propogates the change
4852 to allow just the product name in the server string using
4856 Changes with Apache 2.0a4
4858 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
4859 won't need to call it. [Greg Ames, Jeff Trawick]
4861 *) Move pre_config hook call to between configuration read and config
4862 tree walk. This allows all modules to implement pre_config hooks
4863 and know that they will be called at an appropriate time.
4866 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
4869 *) Add pre-config hooks back to all modules.
4872 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
4873 ContentDigest enabled and we can't/don't mmap the file.
4876 *) We now report the correct line number for syntax errors in config
4877 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
4879 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
4880 related bugs, and changed shmem/locking to use apr API. Shared-mem
4881 is currently disabled, however, because of problems with graceful
4882 restarts. [Ronald Tschalär]
4884 *) Fix corruption of IFS variable in --with-module= handling.
4885 Depending on the user's shell or customization thereof, there
4886 would be errors generating ap_config_auto.h later in the configure
4887 procedure. [Jeff Trawick]
4889 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
4890 isn't used (as in 1.3), except that on Unix it is now logged via
4891 ap_log_rerror() instead of by the child having STDERR_FILENO refer
4892 to the error log. [Greg Ames, Jeff Trawick]
4894 *) Add '-D' argument processing for run time configuration defines.
4897 *) Organize http_main.c as independent code, such that no code or
4898 global data is exported from it. WIN32 will dynamically link it
4899 to the server core, so this will prevent mutual dependency.
4902 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
4903 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
4906 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
4907 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
4909 *) Add mod_charset_lite for configuring character set translation.
4912 *) Add '-n' option to htpasswd to make it print its user:pw record
4913 on stdout rather than having to frob a text file. [Ken Coar]
4915 *) Fix saferead. Basically, we flush the output buffer if a read on the
4919 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
4920 a conversion is single-byte only. [Jeff Trawick]
4922 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
4923 the BeOS 5.0 documentation says that shutdown doesn't work yet.
4926 *) Fix some minor errors where pid was being manipulated as an int
4927 instead of the portable pid_t. [Roy Fielding]
4929 *) Fix some error log prints that were printing the pointer to a
4930 structure rather than the pid within the structure.
4931 [Jeff Trawick, Roy Fielding]
4933 *) ab: Fix a command-line processing bug; track bad headers in
4934 err_response; support reading headers up to 2K.
4935 [Ask Bjoern Hansen <ask@valueclick.com>]
4937 *) Fix ap_resolve_env() so that it handles new function added in a prior
4938 alpha (see "Added the capability to do ${ENVVAR} constructs in the
4939 config file.") as well as the constructs used by mod_rewrite.
4940 [Paul Reder <rederpj@raleigh.ibm.com>]
4942 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
4944 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
4945 APR to perform translation, instead of accessing the hard-coded tables
4946 in 1.3's ebcdic.c. [Jeff Trawick]
4948 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
4951 *) Add the ability to hook into the config file reading phase. Basically
4952 if a directive is specified EXEC_ON_READ, then when that directive is
4953 read from the config file, the assocaited function is executed. This
4954 should only be used for those directives that must muck with HOW the
4955 server INTERPRETS the config. This should not be used for directives
4956 that re-order or replace items in the config tree. Those changes should
4957 be made in the pre-config step.
4960 *) Add mod_example to the build system.
4963 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
4964 byte character sets. [Jeff Trawick]
4966 *) Pick up various EBCDIC fixes from 1.3 (from Martin
4967 Kraemer and Oliver Reh originally according to the change log).
4970 *) Fix a couple of problems in RFC1413 support (controlled by the
4971 IdentityCheck directive). Apache did not build the request string
4972 properly and more importantly Apache would loop forever if the
4973 would-be ident server dropped the connection before sending a
4974 properly terminated response. [Jeff Trawick]
4976 *) apxs works in 2.0.
4979 *) Reliable piped logs work in 2.0.
4982 *) Introduce a hash table implementation into APR to be used for
4983 replacing tables and other random data structures in Apache.
4986 *) Add some more error reporting to htpasswd in the case of problems
4987 generating or accessing the temporary file. Also, pass in a
4988 buffer if the implementation knows how to use it (i.e., if L_tmpnam
4989 is defined). [Ken Coar]
4991 *) Configure creates config.nice now containing your configure
4992 options. Syntax: ./config.nice [--more-options]
4995 *) Fix various return code problems in APR on Win32. For most of
4996 these, APR was returning APR_EEXIST instead of GetLastError()/
4997 WSAGetLastError(). [Jeff Trawick]
4999 *) Make piped logs work again in version 2.0
5002 *) Add VPATH support to UNIX build system of Apache and APR.
5005 *) Fix ap_tokenize_to_argv to respect the const arguments that are
5009 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
5010 Patch submitted to author.
5013 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
5014 /sbin in PATH on FreeBSD (all submitted to rse previously)
5017 *) Fix building Pthread-based MPMs on OpenBSD
5018 [Sascha Schumann] PR#26
5020 *) Fix ap_readdir() problem on systems where d_name[] field in
5021 struct dirent is declared with only one byte. (This problem only
5022 affected multithreaded builds.) This caused a segfault during
5023 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
5024 least). [Jeff Trawick]
5026 *) Fix some make-portability problems on at least Tru64, Irix
5028 [Sascha Schumann] PR#18, PR#39
5030 *) Add ap_sigwait() to support old-style sigwait() on systems
5031 like OS/390 and UnixWare.
5034 *) Add POSIX-thread flags for more platforms.
5037 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
5038 (on Unix, at least) to handle resolver errors. Fix a bug in
5039 the definition of APR_ENOMEM so that ap_strerror() can spit
5040 out the correct error message for it.
5043 Changes with Apache 2.0a3
5045 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
5048 *) API: *HOOK* macros now have an AP_ prefix
5051 *) Win32: Eliminate redundant calls to initialize winsock.
5052 [Tim Costello <timcostello@ozemail.com.au>]
5054 *) Fix bugs initializing ungetchar for pipes.
5055 [Chia-liang Kao <clkao@CirX.ORG>]
5057 *) The ab program in the src/support directory is now portable using
5061 *) Support directory is being compiled when the server is built
5064 *) The configure option --with-program-name has been added to allow
5065 developers to rename the executable at configure time. This also
5066 changes the name of the config files to match the executable's name.
5069 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
5070 containing version numbers. [Martin Pool]
5072 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
5073 Unix; access_log and error_log now created with these perms; non-
5074 Unix is unaffected [Jeff Trawick]
5076 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
5077 Replaced more magic numbers with MD5_DIGESTSIZE.
5078 [William Rowe, Roy Fielding]
5080 *) Win32: Get mod_auth_digest compiling and added to the Windows
5081 build environment. Not tested and I'd be suprised if it
5082 actually works. [Bill Stoddard]
5084 *) Revamp the Win32 make environment. Makefiles have been removed and
5085 Apache.dsw created to bring together all the pieces. Create new file
5086 os/win32/BaseAddr.ref to define module base addresses (to prevent
5087 dll relocation at start-up).
5088 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
5090 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
5091 of the \015, \012, and \015\012 constants with macros.
5094 *) Add ap_xlate_open() et al for translation of text between different
5095 character sets. The initial implementation requires iconv().
5098 *) More FAQs and answers from comp.infosystems.www.servers.unix.
5099 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5101 *) CGI output is being timed out now.
5104 *) Fix the problem with dieing quietly. dupfile now takes a pool which
5105 is used by the new apr file. There is no reason to create a new file
5106 with the same lifetime as the original file.
5109 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
5110 module base addresses. This will help shooting seg faults
5111 in the field. [William Rowe <wrowe@lnd.com>]
5113 *) Update Apache on Windows documentation. Add new document
5114 describing how to compile Apache on Windows.
5115 [William Rowe <wrowe@lnd.com>]
5117 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
5118 microseconds instead of seconds. Some storage leaks and other
5119 minor bugs in related code were fixed. [Jeff Trawick]
5121 *) Win32: First cut at getting mod_isapi working under 2.0
5122 [William Rowe <wrowe@lnd.com>]
5124 *) First stab at getting mod_auth_digest working under 2.0
5125 quick change summary:
5126 - moved the random byte generation (ap_generate_random_bytes) into APR
5127 - now uses ap_time_t
5128 - compiles and runs on linux
5130 [Brian Martin <bmartin@penguincomputing.com>]
5132 *) Win32: Move the space stripping of physical service names
5133 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
5134 unresolved symbol. Add dependency checking to the
5135 CreateService call to ensure TCPIP and AFP (winsock) is started
5137 [William Rowe <wrowe@lnd.com>]
5139 *) Win32: Add code to perform latebinding on functions that may
5140 not exist on all levels of Windows where Apache runs. This
5141 is needed to allow Apache to start-up on Win95/98. All calls
5142 to non portable functions should be protected with
5143 ap_oslevel checks to prevent runtime segfaults.
5144 [William Rowe <wrowe@lnd.com>]
5146 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
5148 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
5150 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
5151 This addresses PR 1623. Still need to address timing out runaway
5152 CGI scripts. [Bill Stoddard]
5154 *) Win32: Make ap_stat Windows 95/98 friendly
5155 [William Rowe <wrowe@lnd.com>]
5157 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
5158 always fail. Need to initialise the dwOSVersionInfoSize member of the
5159 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
5162 The patch also enhances ap_get_oslevel (and the associated enum) to
5163 handle selected service packs for NT4, and adds recognition for
5164 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
5165 we can use ReadFileScatter and WriteFileGather in readwrite.c.
5166 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
5168 *) Get mod_rewrite building and running, and mod_status building for Win NT
5169 [Allan Edwards <ake@raleigh.ibm.com>]
5171 *) Patch to port mod_auth_db to the 2.0 api and also to support
5172 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
5173 2.7.7. It should work with version 1 as well but I haven't tested it.
5174 [Brian Martin <bmartin@penguincomputing.com>]
5176 *) Get APR DSO code working under Windows. Includes cross platform
5178 [Tim.Costello@BTFinancialgroup.com]
5180 *) Fix some of the Windows APR time functions.
5183 *) FAQ changes related to tidying up historical documents on the web site.
5184 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5186 *) Move Windows DSO code into APR.
5189 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
5190 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
5191 at build time. At this point, the server will not compile on Windows because
5192 of the recent DSO commits. Fixing those next.
5193 [Bill Rowe & Bill Stoddard]
5195 *) Added error checking for file I/O APR routines.
5196 [Jon Travis <jtravis@covalent.net>]
5198 *) APR: Don't use the values of resolver error codes for the
5199 corresponding APR error codes. On Unix and Win32, return the
5200 proper APR error code after a resolver error. [Jeff Trawick]
5202 Changes with Apache 2.0a2
5204 *) Renamed the executable back to httpd on all platforms other
5208 *) Allow BeOS to survive restarts, log properly and a few
5209 small things it had problems with due to the way it setup
5210 users and groups. [David Reid]
5212 *) Get mod_rewrite working with APR locks
5213 [Paul Reder <rederpj@raleigh.ibm.com>]
5215 *) Actually remove the sempahore when the lock cleanup routine
5216 is called on BeOS. [David Reid]
5218 *) Clear hook registrations between reads of the config file.
5219 When DSOs are unloaded and re-loaded the old hook pointers may
5220 no longer be valid. This fix eliminates potential segfaults.
5221 [Allan Edwards <ake@raleigh.ibm.com>]
5223 *) Fix a problem with Sigfunc not being defined or bypassed
5224 if sigaction() wasn't found. [Jim Jagielski]
5226 *) Fix the locking mechanism on BSD variants. They now use fcntl
5227 locks. This allows the server to start and serve pages.
5230 *) First cut at getting the Win32 installer to work
5231 [William Rowe <wrowe@lnd.com>]
5233 *) Get htpasswd compiling under Windows
5234 [William Rowe <wrowe@lnd.com>]
5236 *) Change the log message for a bind() failure to show the
5237 interface and port number. [Jeff Trawick]
5239 *) Import the documentation from 1.3.12 and bring parts of it
5240 up-to-date with respect to the changes that have occurred
5244 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
5245 now logged correctly on BeOS.
5248 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
5249 Makefile.win includes the same user interface as the old
5251 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
5253 *) Win32 exec now uses COMSPEC environment string for command
5254 shell path resolution.
5255 [William Rowe <wrowe@lnd.com>] PR#3715
5257 *) Win32: ap_connect() was not returning correct error condition
5259 [Allen Prescott <allen@clanprescott.com>]
5261 *) Win32: ap_open() was broken on Win9x because an NT-specific
5262 flag was passed to CreateFile. ap_puts() added an unnecessary
5264 [Jeff Trawick <trawick@us.ibm.com>]
5266 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
5267 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
5268 confusing ee/et name and made all extensions language/dialect
5269 rather than country reflecting. Changed example files to
5270 explicit reflect the ISO charset and added a few common
5271 ones to the example config [dirkx]
5273 *) Extend external module capability. To use this, you call
5274 configure with --with-module=path/to/mod1,path/to/mod2,etc.
5277 *) Backported the various "default charset" fixes from 1.3.12,
5278 including the AddDefaultCharset directive. [Jim Jagielski]
5280 *) Added the capability to do ${ENVVAR} constructs in the
5281 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
5282 it does this on a line by line basis; i.e. if the envvar
5283 expands to something with spaces you have to protect it
5284 by adding quotes around it (Unless of course you expect it
5285 to contains more than one argument. Alternatively you
5286 can compile it on a per token basis; which is what people
5287 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
5288 hampers fancier hacks.
5289 [Dirk-Willem van Gulik]
5291 *) Changed the 'ErrorDocument' syntax in that it NO longer
5292 supports the asymetric
5294 ErrorDocument 301 "Some message
5296 Note the opening " quote, without a closing quote. It now
5297 has either the following syntaxes
5299 ErrorDocument XXX /local/uri
5300 ErrorDocument XXX http://valid/url
5301 ErrorDocument XXX "Some Message"
5303 The recognition heuristic is: if it has a space it
5304 is a message. If it has no spaces and starts with a /
5305 or is a valid URL then treat it that way. Otherwise it
5306 is assumed to be a message.
5308 This breaks backward compatibility but makes live a hell
5309 of a lot easier for GUI's and config file parsers.
5310 [Dirk-Willem van Gulik]
5312 *) Changed 'CacheNegotiatedDocs' from its present/not-present
5313 syntax into a 'on' or 'off' syntax. As it currently is the
5314 only non nesting token which uses NO_ARGS and thus is an
5315 absolute pain for any config interface automation. This
5316 breaks backward compatibility. [Dirk-Willem van Gulik]
5318 *) Add ability to add external modules to the build process. This is
5319 done with --with-module=/path/to/module. Modules can only be added
5320 as static modules at this point.
5323 Changes with Apache 2.0a1
5325 *) Fix FreeBSD 3.3 core dump.
5326 Basically, ap_initialize() needs to get called before
5327 create_process(), since create_process() passes op_on structure
5328 to semop() to get a lock, but op_on isn't initialized until
5329 ap_initialize() calls setup_lock(). Here is a slight
5330 rearrangement to main() which calls ap_initialize() earlier...
5331 [Jeff Trawick <trawick@us.ibm.com>]
5333 *) Enable Apache to use sendfile/TransmitFile API
5334 [Bill Stoddard, David Reid, Paul Reder]
5336 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
5340 *) Make file I/O and network I/O writev/sendv APIs consistent.
5341 Eliminate use of ap_iovec_t and use Posix struct iovec.
5342 Use seperate variable on ap_writev to set the number of iovecs
5343 passed in and number of bytes written.
5346 *) Adapt file iol to use APR functions. Replaced ap_open_file()
5347 with ap_create_file_iol(). ap_create_file_iol() requires that
5348 the file be opened prior to the call using ap_open().
5351 *) Port mod_include and mod_cgi to 2.0
5352 [Paul Reder, Bill Stoddard]
5354 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
5355 bytes_read/bytes_written is always valid (never -1). Plus
5356 some fixes to buff.c to correct problems introduced by the
5357 errno => ap_status_t changes a while back. Plus a fix to
5358 chunked encoding introduced right at the beginning of 2.0.
5361 *) Revamped UNIX build system to use autoconf and libtool.
5362 [Manoj Kasichainula, Sascha Schumann]
5364 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
5366 *) SECURITY: More rigorous checking of Host: headers to fix security
5367 problems with mass name-based virtual hosting (whether using mod_rewrite
5368 or mod_vhost_alias).
5369 [Ben Hyde, Tony Finch]
5371 *) Add back support for UseCanonicalName in <Directory> containers.
5372 [Manoj Kasichainula]
5374 *) Added APLOG_STARTUP log type. This allows us to write an error
5375 message without any of the date and time information. As a part
5376 of this change, I also removed all of the calls to fprintf(stderr
5377 and replaced them with calls to ap_log_error using APLOG_STARTUP
5378 writing to stderr is no longer portable, because we don't direct
5379 stderr to the error log on all platforms.
5382 *) Convert error logging functions to take errno as an argument.
5383 This makes our error logs more portable, because some Windows API's
5384 don't set errno. This change allows us to still output a valid
5385 message on all of our platforms.
5388 *) mod_mime_magic runs in 2.0-dev now.
5389 [Paul Reder <rederpj@raleigh.ibm.com>]
5391 *) sendfile has been added to APR.
5392 [John Zedlewski <zedlwski@Princeton.EDU>]
5394 *) buff.c has been converted to no longer use errno.
5395 [Manoj Kasichainula]
5397 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
5398 interface adaption to APR functions did it. [Martin Kraemer]
5400 *) Support DSOs properly on 32-bit HP-UX 11.0
5401 [Dilip Khandekar <dilip@cup.hp.com>]
5403 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
5404 [Ralf S. Engelschall]
5406 *) Cleaned APR build environment integration and bootstrap APR
5407 automatically for developers from src/Configure.
5408 [Ralf S. Engelschall]
5410 *) Fixed building of src/support/htpasswd.c
5411 [Ralf S. Engelschall]
5413 *) When generating the Location: header, mod_speling forgot
5414 to escape the spelling-fixed uri. (Forw-Port from 1.3)
5417 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
5419 *) Change all pools to APR contexts. This is the first step to
5420 incorporating APR into Apache. [Ryan Bloom]
5422 *) Move "handler not found" warning message to below the check
5423 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
5424 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
5426 *) Support line-continuation feature in config.option file and
5427 allow the loading of multiple option sections at once via
5428 ``--with-option=<section1>,<section2>,...''
5429 [Ralf S. Engelschall]
5431 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
5433 Changes with Apache MPM
5435 *) Use asynchronous AcceptEx() and a completion port to accept and
5436 dispatch connections to threads in Windows NT/2000.
5439 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
5442 *) Implement the APACI --with-option facility
5443 (per default used the config.option file).
5444 [Ralf S. Engelschall]
5446 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
5448 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
5449 Replace pre_connection module call with a register_hook call and
5450 implement pre_connection as a hook. The intent is that these hooks will
5451 be extended to allow Apache to be multi-protocol, and also to allow the
5452 calling order to be specified on a per-hook/per-module basis.
5455 *) Implement mpm_* methods as "modules". Each method gets its own
5456 subdir in src/modules (eg: src/modules/prefork). Selection
5457 of method uses Rule MPM_METHOD. [Jim Jagielski]
5459 *) Port the hybrid server from the apache-apr repository as
5460 mpm_mpmt_pthread. [Manoj Kasichainula]
5462 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
5463 amongst the unix MPMs.
5465 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
5466 signal handling for the new world order. [Dean Gaudet]
5468 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
5469 of alloc.c for now. [Dean Gaudet]
5471 *) Handle partial large writes correctly. [Ben Laurie]
5473 *) Eliminate conn_rec's pointer to server. All it knows is the base server
5474 based on IP/port. [Ben Laurie]
5476 *) Port a bunch of modules to the new module structure.
5477 ["Michael H. Voase" <mvoase@midcoast.com.au>]
5479 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
5481 *) Basic restructuring to introduce the MPM concept; includes various
5482 changes to the module API... better described by
5483 docs/initial_blurb.txt. [Dean Gaudet]
5485 Changes with Apache pthreads
5487 *) New buff option added: BO_TIMEOUT. It describes the timeout for
5488 buff operations (generally over a network).
5489 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
5491 *) Created http_accept abstraction. Added 4 new functions (not exported):
5492 init_accept(), begin_accepting_requests(), get_request(),
5493 stop_accepting_requests() [Bill Stoddard]
5495 *) Fix to ap_rprintf call that allows mod_info to work properly.
5496 [James Morris <jmorris@intercode.com.au>]
5498 *) user and ap_auth_type fields were moved from connection_rec to
5499 request_rec. [Ryan Bloom]
5501 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
5502 needed in a threaded server.
5504 *) Initial pthread implementation from from Dean's apache-nspr code.
5505 [Bill Stoddard, Ryan Bloom]
5508 Changes with Apache 1.3.9
5510 *) Remove bogus error message when a redirect doesn't set Location.
5511 Instead, use an empty string to avoid coredump if the error message
5512 was supposed to include a location. [Roy Fielding]
5514 *) Don't allow configure to include mod_auth_digest unless it is
5515 explicitly requested, even if the user asked for all modules.
5518 *) Translate module names to dll names for OS/2 so that they are no more
5519 than 8 characters long and have an extension of "dll" instead of "so".
5522 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
5523 Fix test-compile check to check for randbyte instead of trand32.
5524 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
5525 and tweak to make Amaya happier. [Ronald Tschalär]
5527 *) Ensure that the installed expat include files are world readable,
5528 just like the other header files. [Martin Kraemer]
5530 *) Fixed generated AddModule adjustments in APACI's `configure' script
5531 in order to allow (new) modules like mod_vhost_alias to be handled
5532 correctly (which was touched by the adjustments for mod_alias).
5533 [Ralf S. Engelschall]
5535 *) For binary builds, add -R flag to apachectl to work around the lack of
5536 an absolute path to the ./libexec directory where the libhttp.ep file
5537 is needed for SHARED_CORE architectures. [Randy Terbush]
5539 *) WIN32: Create the CGI script process as DETACHED. This may solve the
5540 problem observed by some Win95/98 users where they get CGI script
5541 output sent to the console. [Bill Stoddard]
5543 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
5544 routines are now called ap_base64* and are 'plain' (i.e., no
5545 pool access or anything clever). Inside util.c the routines acting
5546 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
5547 The oddly named ap_uuencode(), ap_uudecode() are kept around for
5548 now but deprecated. [dirkx]
5550 *) Clean up the base64 and SHA1 additions and make sure they are
5551 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
5552 files. [Roy Fielding]
5554 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
5555 checking. Allow compiling on VS 6.0. [Randy Terbush]
5557 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
5559 *) Use TestCompile to search for the truerand library (rather than blindly
5560 assuming its existence). If it is not found, complain (but do not
5561 exit - yet). [Martin Kraemer]
5563 *) We forgot to add the new exported function names to
5564 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
5566 *) Add description of -T command-line option to usage().
5567 [Ralf S. Engelschall]
5569 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
5570 searched only AFTER libap has been searched, because libap needs
5571 some symbols from libos. [Martin Kraemer]
5573 *) Fix conflict with original mod_digest related to the symbol of the
5574 module dispatch list (which has to be unique for DSO and follow the
5575 usual conventions for the installation procedure).
5576 [Ralf S. Engelschall]
5578 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
5579 for other platforms as well. [Martin Kraemer]
5581 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
5582 types by AP_LONG and replace reference to renamed variable 'ubuf'
5583 by 'buffer'. [Martin Kraemer]
5585 Changes with Apache 1.3.8 [not released]
5587 *) Flush the output buffer immediately after sending an error or redirect
5588 response, since the result may be needed by the client to abort a
5589 long data transfer or restart a series of pipelined requests.
5590 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
5592 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
5593 [Ian Turner <iant@sequent.com>] PR#4735
5595 *) Local struct mmap in http_core.c conflicted with system structure
5596 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
5598 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
5599 [Ronald Tschalär <ronald@innovation.ch>]
5601 *) Fix a memory leak where the module counts were getting messed
5602 up across restarts. [David Harris <dharris@drh.net>]
5604 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
5605 properly in mod_access.
5606 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
5608 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
5609 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
5611 *) PORT: Support for compaq/tandem/com.
5612 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
5614 *) Added SHA1 password encryption support to easy migration from
5615 Netscape servers. See support/SHA1 for more information.
5616 Caused the separation of ap_md5.c into md5, sha1 and a general
5617 ap_checkpass.c with just a validate_passwd routine. Added a
5618 couple of flags to support/htpasswd. Some reuse of the to64()
5619 function; hence renamed to ap_to64().
5620 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
5622 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
5623 with ASCII/EBCDIC conversions in "ident" query.
5624 [David McCreedy <McCreedy@us.ibm.com>]
5626 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
5627 Change "Power Macintosh" to Power* so if uname prints "Power Book"
5628 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
5630 *) Fix SIGSEGV on some systems because the Vary fix below included
5631 a call to table_do with a variable argument list that was not
5632 NULL terminated. Replaced with better implementation. [Roy Fielding]
5634 Changes with Apache 1.3.7 [not released]
5636 *) The "Vary" response header field is now sanitised right before
5637 the header is sent back to the client. Multiple "Vary" fields
5638 are combined, and duplicate tokens (e.g., "Vary: host, host" or
5639 "Vary: host, negotiate, host, accept-language") are reduced to
5640 single instances. This is a better solution than the force-no-vary
5641 one (which is still valid for clients that can't cope with Vary
5642 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
5644 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
5646 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
5647 least on Linux and FreeBSD for now.
5650 *) Win32: More apache -k restart work. Restarts are now honored
5651 immediately and connections in the listen queue are -not- lost.
5652 This is made possible by the use of the WSADuplicateSocket()
5653 call. The listeners are opened in the parent, duplicated, then
5654 the duplicates are passed to the child. The original listen sockets
5655 are not closed by the parent across a restart, thus the listen queue
5657 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5659 *) Fix handling of case when a client has sent "Expect: 100-continue"
5660 and we are going to respond with an error, but get stuck waiting to
5661 discard the body in the pointless hope of preserving the connection.
5662 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
5664 *) Fix 'configure' to work correctly with SysV-based versions of
5665 'tr' (consistent with Configure's use as well). [Jim Jagielski]
5667 *) apxs: Add "-S var=val" option which allows for override of CFG_*
5668 built-in values. Add "-e" option which works like -i but doesn't
5669 install the DSO; useful for editing httpd.conf with apxs. Fix
5670 editing code so that multiple invocations of apxs -a will not
5671 create duplicate LoadModule/AddModule entries; apxs can now be
5672 used to re- enable/disable a module. [Wilfredo Sanchez]
5674 *) Win32: Update the server to use Winsock 2. Specifically, link with
5675 ws2_32.lib rather than wsock32.lib. This gives us access to
5676 WSADuplcateSocket() in addition to some other enhanced comm APIs.
5677 Win 95 users may need to update their TCP/IP stack to pick up
5678 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
5679 [Bill Stoddard stoddard@raleigh.ibm.com]
5681 *) Win32: Redirect CGI script stderr (script debug info) into the
5682 error.log when CGI scripts fail. This makes Apache on Win32
5683 behave more like Unix.
5684 [Bill Stoddard stoddard@raleigh.ibm.com]
5686 *) Fixed `httpd' usage display: -D was missing.

5693 "OS2SEM: Error 105 getting accept lock. Exiting!"
5694 [Brian Havard] PR#4505
5696 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
5697 [Randy Terbush <randy@covalent.net>]
5699 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
5700 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
5702 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
5703 command potentially _is_ GCC. [Ralf S. Engelschall]
5705 *) Fix apxs build issues on AIX
5706 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
5708 *) DocumentRoot Checking: Under previous versions, when Apache
5709 first started up, it used to do a stat of each DocumentRoot to
5710 see if it existed and was a directory. If not, then an error
5711 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
5712 does not exist, you will get error messages in error_log. If
5713 the '-t' command line option is used (to check the configuration)
5714 the check of DocumentRoot IS performed. An additional command
5715 line option, '-T', has been added if you want to avoid the
5716 DocumentRoot check even when checking the configuration.
5719 *) Win32: The query switch "apache -S" didn't exit after showing the
5720 vhost settings. That was inconsistent with the other query functions.
5721 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
5723 *) Win32: Changed behaviour of apache -k restart.
5724 Previously, the server would drain all connections in the stack's
5725 listen queue before honoring the restart. On a busy server, this
5726 could take hours. Now, a restart is honored almost immediately.
5727 All connections in Apache's queues are handled but connections in
5728 the stack's listen queue are discarded. Restart triggered by
5729 MaxRequestPerChild is unchanged.
5730 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5732 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
5733 the accept loop. Good for a 5% performance boost. Cleaned up
5734 parent/child process management code.

5747 *) Allow .module files to specify libraries with Lib:.
5750 *) Allow SetEnvIf[NoCase] to test environment variables as well
5751 as header fields and request attributes. [Ken Coar]
5753 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
5754 content-types are "text/html;parameters". PR#4524 [Ken Coar]
5756 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
5757 never accepted into any standard, and it opens up certain DoS
5758 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
5760 *) TestCompile updated. We can now run programs and output the
5761 results during the Configure process. [ Jim Jagielski]
5763 *) The source is now quad (long long) aware as needed. Specifically,
5764 the Configure process determines the correct size of off_t and
5765 *void. When the OS/platform/compiler supports quads, ap_snprintf()
5766 provides for the 'q' format qualifier (if quads are not available,
5767 'q' is silently "demoted" to long). [Jim Jagielski]
5769 *) When the username or password fed to htpasswd is too long, include the
5770 size limit in the error message. Also report illegal characters
5771 (currently only ':') in the username. Add the size restrictions
5772 to the man page. [Ken Coar]
5774 *) Fixed the configure --without-support option so it doesn't result in
5775 an infinite loop. [Marc Slemko]
5777 *) Piped error logs could cause a segfault if an error occured
5778 during configuration after a restart.
5779 [Aidan Cully <aidan@panix.com>] PR#4456
5781 *) If a "Location" field was stored in r->err_headers_out rather
5782 than r->headers_out, redirect processing wouldn't find it and
5783 the server would core dump on ap_escape_html(NULL). Check both
5784 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
5785 if Location isn't set. [Doug MacEachern, Ken Coar]
5787 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
5788 of the Expat 1.0.2 distribution. [Greg Stein]
5790 *) Replace regexec() calls with calls to a new API stub function
5791 ap_regexec(). This solves problems with DSO modules which use the regex
5792 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
5794 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
5795 environment variables can be set according to the protocol version
5796 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

5813 *) Support for server-parsed and multiview-determined ReadmeName and
5814 HeaderName files in mod_autoindex. Removed the restriction on
5815 "/"s in ReadmeName and HeaderName directives since the *sub_req*
5816 routines will deal with the access issues. (It's now possible to
5817 have {site|group|project|customer|...} wide readmes and headers.)

5828 handful of problems seen with mod_perl <Perl> configuration sections
5829 [Salvador Ortiz Garcia <sog@msg.com.mx>]
5831 *) Mac OS and Mac OS X Server now use the appropriate custom layout
5832 by default when building with APACI; allow for platform-specific
5833 variable defaults in configure. [Wilfredo Sanchez]
5835 *) Do setgid() before initgroups() in http_main; some platforms
5836 zap the grouplist when setgid() is called. This was fixed in
5837 suexec earlier, but the main httpd code missed the change.

5853 being newer than Configuration so that it is less likely to fail
5854 when using APACI and shadow sources. [Wilfredo Sanchez]

5857 greater). Use Mac OS X Server layout for now. Clean up dyld code
5858 in unix/os.c, and don't install the dyld error handlers, which
5859 are no longer needed in Mac OS. [Wilfredo Sanchez]
5861 *) Rename Rhapsody layout to "Mac OS X Server". Change install
5862 locations to appropriate ones for user-built (as opposed to
5863 system) installs. [Wilfredo Sanchez]
5865 *) Modify mod_autoindex's handling of AddDescription so that the
5866 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
5868 *) Add functionality to the install-bindist.sh script created by
5869 binbuild.sh to use tar when copying distribution files to the
5870 serverroot. This allows upgrading an existing installation
5871 without nesting the new distribution in the old.
5873 install-bindist.sh now detects the local perl5 path to install
5874 apxs and dbmmanage with proper path to perl interpreter.
5876 Add an install-binsupport target which copies the source files
5877 for apxs and dbmmanage to bindist to allow these scripts to
5878 be properly installed relative to the destination serverroot.

6000 a) the htdigest utility overwrote the old contents of the digest file
6001 b) the Content-MD5 header value (ContentDigest directive) was wrong
6002 when the returned file was not converted from EBCDIC, but was a
6003 binary (e.g., image file) in the first place.
6004 [David McCreedy <mccreedy@us.ibm.com>]

6045 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
6046 a roughly 5 fold speed up. [Brian Havard]
6048 *) proxy ftp: instead of using the hardwired string "text/plain" as
6049 a fallback type for files served by the ftp proxy, use the
6050 ap_default_type() function to determine the configured type.
6051 This allows for special configurations like
6052 <Directory proxy:ftp://some.host>
6053 DefaultType gargle/blurb
6055 Additionally, add the Content-Encoding: header to FTP proxy replies
6056 when the encoding is defined (by the AddEncoding directive).
6057 Because it was missing, it was almost impossible to browse compressed
6058 files using the FTP proxy (works now perfectly in Communicator).
6059 The ftp proxy now also returns the Date: and Server: header lines (if not
6060 much else... This code is "somewhat" broken) like normal requests do.
6063 *) Be more smart in APACI's configure script when determining the UID/GID
6064 for User/Group directives and use the determined UID/GID to initialize
6065 the permissions on the proxycachedir.
6066 [Dirk-Willem van Gulik, Ralf S. Engelschall]
6068 *) Changed the forking-prior-to-cleanup in the proxy module to first

6180 *) In configure, do not append the target name to the directory path if
6181 the path already contains "apache". [Ralf S. Engelschall]
6183 *) SIGPIPE is now ignored by the server core. The request write routines
6184 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
6185 correctly check for output errors and mark the connection as aborted.
6186 Replaced many direct (unchecked) calls to ap_b* routines with the
6187 analogous ap_r* calls. [Roy Fielding]
6189 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
6190 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
6191 Furthermore map lookups for non-existent keys are now cached as well.
6192 Additionally "txt" maps are now parsed with simple string functions
6193 instead of using ap_pregcomp(). As a side effect a bug that prevented
6194 the usage of keys containing the "," character was fixed.
6195 The changes drastically improve the performance when large rewrite maps
6197 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
6199 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
6200 other than GET, and const'd the definition of method in request_rec.
6203 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
6205 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
6206 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
6208 *) Add %V to mod_log_config, this logs the hostname according to the
6209 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
6210 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
6212 *) Add support for \n and \t to mod_log_config, can be used to produce
6213 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
6215 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
6217 *) Added informative error messages for failed munmap() and fseek() calls
6218 in http_core.c. [John Bley, Roy Fielding]
6220 *) Added some informative error messages for some failed malloc()
6221 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
6223 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
6224 is removed. This allows <Directory proxy:*> directives to work and
6225 prevents invalid requests from killing the process.
6226 [Brian Havard <brianh@kheldar.apana.org.au>]
6228 *) Reorganised FAQ document.
6229 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
6231 *) src/support/: The ApacheBench benchmark program was overhauled by
6232 David N. Welton: you can now have it generate an HTML TABLE, presumably
6233 for integration into other HTML sources. David updated the ab man page
6234 as well and added some missing descriptions. Thanks!
6235 [David N. Welton <davidw@prosa.it>]
6237 *) Win32: The filename validity checker now allows filenames containing
6238 characters in the range 0x80 to 0xff (for example accented characters).
6239 [Paul Sutton] PR#3890
6241 *) Added conditional logging based upon environment variables to
6242 mod_log_config. mod_log_referer and mod_log_agent
6243 are now deprecated. [Ken Coar]
6245 *) Allow apache acting as a proxy server to relay the real
6246 reason of a failure to a client rather than the "internal
6247 server error" it does currently. The general exposure mechanism
6248 can be triggered by any module by setting the "verbose-error-to"
6249 note to "*"; this allows more than just proxy errors to be exposed.
6250 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
6252 *) Moved man pages for ab and apachectrl to section 8.
6253 [Wilfredo Sanchez, Roy Fielding]
6255 *) Added -S option to install.sh so that options can be passed to
6256 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
6258 *) Tweak modules Makefile generated by Configure so that it handles
6259 the test case of no modules being selected. [chaz@reliant.com]
6261 *) Added a <LimitExcept method ...> sectioning directive that allows
6262 the user to assign authentication control to any HTTP method that
6263 is *not* given in the argument list; i.e., the logical negation
6264 of the <Limit> directive. This is particularly useful for controlling
6265 access on methods unknown to the Apache core, but perhaps known by
6266 some module or CGI script. [Roy Fielding, Tony Finch]
6268 *) Prevent apachectl from complaining if the PIDFILE exists but
6269 does not contain a process id, as might occur if the server is
6270 being rapidly restarted. [Wilfredo Sanchez]
6272 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
6274 *) Entity tag comparisons for If-Match and If-None-Match were not being
6275 performed correctly -- weak tags might cause false positives. Also,
6276 strong comparison wasn't properly enforced in all cases.
6277 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
6279 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
6282 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
6283 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
6285 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
6286 to util.c for parsing an HTTP header field value to extract the next
6287 list item, taking into account the possible presence of nested comments,
6288 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
6289 insignificant whitespace and lowercases non-quoted tokens.
6290 [Roy Fielding] PR#2065
6292 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
6293 code different from 500. This allows the proxy to, e.g., return
6294 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
6296 *) Fix ordering of language variants for the case where the traditional
6297 negotiation algorithm is being used with multiple language variants
6298 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
6300 *) Do not round the TCN quality calculation to 5 decimal places,
6301 unlike RFC 2296, because the calculation might need 12 decimal places
6302 to get the right result. [Roy Fielding]
6304 *) Remove unused code to disable transparent negotiation when
6305 negotiating on encoding only, as we now handle encoding too
6306 (though this is nonstandard for TCN), remove charset=ISO-8859-1
6307 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
6308 some debugging statements within mod_negotiation. [Koen Holtman]
6310 *) Fixed a rare memory corruption possibility in mod_dir if the index
6311 file is negotiable and no acceptable variant can be found.
6312 [Dean Gaudet, Roy Fielding, Martin Kraemer]
6314 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
6315 searching the Win32 registry for script interpreters.
6318 *) Win32: The compiled-in default filename for the error log is now
6319 error.log, which matches the default in the distributed httpd.conf.
6322 *) Win32: Any error messages from -i or -u command line options are now
6323 displayed on the console output rather than sent to the error log.
6324 Also the "Running Apache..." message is not output unless Apache is
6325 going to serve requests. [Paul Sutton]
6327 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
6328 and use a private significator ('$apr1$') to mark passwords as
6329 being smashed with our own algorithm. Also abstract the password
6330 checking into a new ap_validate_password() routine. [Ken Coar]
6332 *) Win32: The filename validity checker now allows "COM" but refuses
6333 access to "COM1" through "COM4". This allows filenames such
6334 as "com.name" to be served. [Paul Sutton] PR#3769.
6336 *) BS2000: Adapt to the new ufork() system call interface which will
6337 make subtasking easier on the OSD/POSIX mainframe environment.
6340 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
6341 ap_compat.h. [David White <david@persimmon.com>] PR#3725
6343 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
6344 use `.db' instead of `.pag' not only for FreeBSD, but also when
6345 the NDBM library looks like Berkeley-DB based.
6346 [Ralf S. Engelschall] PR#3773
6348 *) Add ability to handle DES or MD5 authentication passwords.
6349 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
6351 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
6353 *) SECURITY: Avoid some buffer overflow problems when escaping
6354 quoted strings. (This overflow was on the heap and we believe
6355 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
6357 *) Let src/Configure be aware of CFLAGS options starting with plus
6358 signs as it's the case for the HP/UX compiler.
6359 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
6361 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
6362 and check to see if the tar we wind up with supports '-h'.
6363 [Jim Jagielski] PR#3671
6365 *) A consistent and conservative style for all shell scripts has been
6366 implemented. Basically, all shell string tests use the traditional
6367 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
6368 to protect against bare null variable strings (ie: wrapping both
6369 sides with double quotes and prepending 'x'). 'x' was chosen
6370 because it's more universal and hopefully easier for old shell
6371 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
6374 *) The status module now prints out both the main server generation as
6375 well as the generation of each process. Also, the vhost info is
6376 printed with '?notable'. [Jim Jagielski]
6378 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
6379 and this makes its functions available to things in src/support.
6382 Changes with Apache 1.3.4
6384 *) Renamed macros status_drops_connection to ap_status_drops_connection
6385 and vestigial scan_script_header to ap_scan_script_header_err,
6386 mostly for aesthetic reasons. [Roy Fielding]
6388 *) The query switch "httpd -S" didn't exit after showing the
6389 vhost settings. That was inconsistent with the other query functions.
6392 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
6393 filename to the end of the STANDARD_MODULE_STUFF. Its
6394 presence at the beginning prevented reporting of the filename
6395 for modules compiled before 1 January 1999. [Ken Coar]
6397 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
6398 to detect and prevent access to special DOS device file names.
6399 [Paul Sutton, Ken Parzygnat]
6401 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
6402 and Makefile_win32_debug.txt (debug build) that work on Win95.
6403 Run each of the following from the src directory:
6404 nmake /f Makefile_win32.txt # compiles normal build
6405 nmake /f Makefile_win32.txt install # compiles and installs
6406 nmake /f Makefile_win32.txt clean # removes compiled junk
6407 nmake /f Makefile_win32_debug.txt # compiles debug build
6408 nmake /f Makefile_win32_debug.txt install
6409 nmake /f Makefile_win32_debug.txt clean
6412 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
6413 to build binary distributions. [Lars Eilebrecht]
6415 *) IndexOptions SuppressColumnSorting only turned off making
6416 the column headers anchors; you could still change the display
6417 order by manually adding a '?N=A' or similar query string to the
6418 URL. Now SuppressColumnSorting locks in the sort order so
6419 it can't be overridden this way. [Ken Coar]
6421 *) Added IndexOrderDefault directive to supply a default sort order
6422 for FancyIndexed directory listings. [Ken Coar] PR#1699
6424 *) Change the ap_assert macro to a variant that works on all platforms.
6425 [Richard Prinz <richard.prinz@cso.net>] PR#2575
6427 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
6428 search for an underscore on dlsym() (as it's already the case
6429 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
6431 *) Small fix for mod_env.html: The module was documented as to be _not_
6432 compiled into Apache per default, although it _IS_ compiled into
6433 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
6435 *) Instead of fixing a bug in the generation procedure for config.status (a
6436 backslash was missing) we remove the bug together with it's complete
6437 context because the special cases of the past can now no longer occur
6438 because of the recent magic for the --with-layout default.
6439 [Ralf S. Engelschall] PR#3590
6441 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
6442 making sure the src/support/ tools are _forced_ to be build last (they
6443 depend on other libraries).
6444 [Markus Theissinger <markus.theissinger@gmx.de>]
6446 *) Fix installation procedure: Now that os-inline.c is actually used (a
6447 recently fixed bug prevented this) we need to also install os-include.c
6448 in addition to os.h into the PREFIX/include/ location or building of
6449 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
6451 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
6452 allow us to distinguish between a garbled DSO (or even a file which isn't
6453 an Apache module DSO at all) and a DSO which doesn't match the current
6454 Apache API. [Ralf S. Engelschall] PR#3152
6456 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
6457 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
6458 match case insensitive (this especially avoids nasty patterns like
6459 `[tT][eE][sS][tT]'). Second two additional internal map functions
6460 `escape' and `unescape' were added which can be used to escape/unescape
6461 to/from hex-encodings in URLs parts (this is especially useful in
6462 combination with map lookups).
6463 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
6465 *) Renamed the macro escape_uri() to ap_escape_uri() which was
6466 forgotten (because it was a macro) in the symbol renaming process.
6467 [Ralf S. Engelschall]
6469 *) Fix some inconsistencies related to the scopes of directives. The only
6470 user visible change is that the directives `UseCanonicalName' and
6471 `ContentDigest' now use the (more correct) `Options' scope instead of
6472 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
6474 *) Using DSO, the Server token was being mangled. Specifically, the
6475 module's token was being added first before the Apache token. This
6476 has been fixed. [Jim Jagielski]
6478 *) Major overhaul of mod_negotiation.c, part 2.
6479 - properly handle "identity" within Accept-Encoding.
6480 - allow encoded variants in RVSA negotiation and let them appear in
6481 the Alternates field using the non-standard "encoding" tag-list.
6482 - fixed both negotiation algorithms so that an explicitly accepted
6483 encoding is preferred over no encoding if "identity" is not
6484 included within Accept-Encoding.
6485 - added ap_array_pstrcat() to alloc.c for efficient concatenation
6486 of large substring sequences.
6487 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
6490 *) Major overhaul of mod_negotiation.c, part 1.
6491 - cleanups to mod_negotiation comments and code structure
6492 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
6493 support for everything in the upcoming HTTP/1.1
6494 revision (draft-ietf-http-v11-spec-rev-06.txt).
6495 - language tag matching also handles tags with more than 2
6497 - empty Accept, Accept-Language, Accept-Charset headers are
6498 processed correctly; previously an empty header would make all
6499 values acceptable instead of unacceptable.
6500 - allowed for q values in Accept-Encoding
6501 - added support for transparent content negotiation (rfc2295 and
6502 rfc2296) (though we do not implement all features in these drafts,
6503 e.g. no feature negotiation). Removed old experimental version.
6504 - implemented 'structured entity tags' for better cache correctness
6505 (structured entity tags ensure that caches which can deal with Vary
6506 will (eventually) be updated if the set of variants on the server
6508 - this involved adding a vlist_validator element to request_rec
6509 - this involved adding the ap_make_etag() function to the global API
6510 - modified guessing of charsets used by Apache negotiation algorithm
6511 to guess 'no charset' if the variant is not a text/* type
6512 - added code to sort multiviews variants into a canonical order so that
6513 negotiation results are consistent across backup/restores and mirrors
6514 - removed possibility of a type map file resolving to another type map
6515 file as its best variant
6516 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
6518 *) RFC2396 allows the syntax http://host:/path (with no port number)
6519 but the proxy disallowed it (ap_proxy_canon_netloc()).
6520 [David Kristol <dmk@bell-labs.com>] PR#3530
6522 *) When modules update/modify the file name in the configfile_t structure,
6523 syntax errors will report the updated name, not the original one.
6524 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
6526 *) Correct some filename case assumptions from WIN32 to
6527 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
6529 *) For %v log ServerName regardless of the UseCanonicalName
6530 setting (similarly for %p). [Dean Gaudet]
6532 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
6533 rather late (too late for some invocations of TestCompile).
6534 This improves the make environment available to TestCompile and
6535 the *.module scripts. [Martin Kraemer]
6537 *) The hashbang emulation code in ap_execve.c would interpret
6538 #!/hashbang/scripts correctly, but failed to fall back to a
6539 standard shell for scripts which did NOT start with #!
6540 Now SHELL_PATH is started in these cases. [Martin Kraemer]
6542 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
6545 *) Update APXS manual page: some -q option arguments were missing
6546 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
6548 *) Cleanup the command line options: `-?' was documented to show
6549 the usage list but does it with an error because `?' is not a valid
6550 command. OTOH a lot of users expect `-h' to print such a usage list and
6551 instead are annoyed for ages by our huge unreadable list of directives.
6552 So we now changed the command line options this way:
6554 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
6555 very similar to the popular linker option.
6557 Intent: while -l gives the small list of modules, -L now gives the
6558 large list of directives implemented by these modules. This is also
6559 consistent with -v (short version info) and -V (large version info).
6561 Intent: it's now the expected option ;-)
6562 The manual page was adjusted accordingly.
6563 [Ralf S. Engelschall] PR#2714
6565 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
6566 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
6568 *) Removed recently introduced bugs and disfigurements in APACI:
6569 o fixed argument line processing: using $args was broken: It was not
6570 initialized and using args="$args $apc_option" and even args="$args
6571 \"$apc_option\"" fails in the second processing round for any arguments
6572 containing whitespaces. The only correct way is to use the construct
6573 "$@" (but not possible here) or iterate _both_ times over the implicit
6574 argument line (no argument to for-loop) which is what we now use.
6575 o make --with-layout=Apache the default without creating
6576 redundancy (copying the --with-layout block in the argument parsing
6577 loop). We achieve this by using the "$@" construct together with the
6578 `set' command to prepend --with-layout=Apache to the command line in
6579 case --with-layout is not used.
6580 o fixed auto-suffix handling now that config.layout exists.
6581 Paths which are auto-suffixed are marked with a trailing plus sign in
6582 config.layout and every path now can be marked this way (not only the
6583 four paths for which we do it currently). Additionally the suffix is
6584 no longer a static one. Instead it's now `/<target>' where <target> is
6585 the argument of the --target option or per default `httpd'.
6586 o allow also tabs (and only spaces) where we match whitespaces
6587 o various fixes and cleanups related to used shell coding style
6588 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
6589 o trimmed output of --help to fit into 80 columns
6590 [Ralf S. Engelschall]
6592 *) Added two new core API functions, ap_single_module_configure() and
6593 ap_single_module_init(), which are now used by mod_so to configure a module
6594 after loading. [Ralf S. Engelschall]
6596 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
6597 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
6598 of ap_config.h to allow serialized accept for multiport listens.
6599 [Roy Fielding, Curt Sampson] PR#3120
6601 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
6602 of ap_config.h that would skip several defines if DEFAULT_GROUP
6603 was overridden. [Roy Fielding]
6605 *) PORT: The I86 version of DGUX has support for strncasecmp and
6606 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
6608 *) Fix ordering of definitions in ap_config.h so that ap_inline is
6609 defined before it might be used. [Victor Khimenko]
6611 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
6612 [Tom Serkowski <tks@bsdi.com>] PR#3453
6614 *) Make generation of src/Configuration.apaci more robust: It failed to
6615 differenciate between modules when one module name was a postfix of
6616 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
6617 just XXX (think about totally non-standard names like "apache_ssl", too).
6618 [Ralf S. Engelschall] PR#3380
6620 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
6621 since 1.3b7) and make whitespace handling more robust (it failed horrible
6622 when whitespaces were present in the arguments of -D options).
6623 [Ralf S. Engelschall] PR#3240
6625 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
6626 creates an external package shadow tree in DIR before the local build
6627 shadow tree is generated under DIR. This way one can have the extracted
6628 Apache distribution tree read-only on NFS or CDROM and still build Apache
6629 from these sources. An automatically triggered VPATH-like mechanism is
6630 provided through the TOP variable, too.
6631 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
6633 *) Fix negotiation so that a Vary response header is correctly
6634 generated when, for a particular dimension, variants only vary
6635 in having or not having a value for that dimension. [Paul Sutton]
6637 *) Fix negotiation so that we prefer an encoded variant over an
6638 unencoded variant if the user-agent explicitly says it can
6639 accept that encoding. Previously we always preferred the unencoded
6641 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
6643 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
6644 and the usage page was inconsistent with the functionality and manpage.
6645 [Ralf S. Engelschall]
6647 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
6648 They can occur multiple times and their arguments (`xxx') are passed AS
6649 IS to the compiler/linker command. [Ralf S. Engelschall]
6651 *) Fixed possible (but harmless in practice) bug in the DBM lookup
6652 procedure of mod_rewrite: very long keys were truncated.
6653 [Ralf S. Engelschall]
6655 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
6656 identifier, currently "Apache" and "GNU" are pre-defined in the file
6657 config.layout. Custom layouts are possible by using FILE:ID as the
6658 argument where the layout ID is taken from FILE.
6660 The config.layout file consists of <Layout ID>..</Layout> sections
6661 where inside those sections "path_variable: path_value" pairs can be
6662 specified. These lines are converted to path_variable='path_value'.
6664 *) Add a DefaultLanguage directive so that files missing a language
6665 extension (e.g., .fr, .de) can be labelled as being some other
6666 default language. DefaultLanguage can appear in <Directory> and
6667 <Files> containers as well as .htaccess files. [Paul Sutton]
6670 *) Fix TARGET configuration when configuring and installing using
6671 APACI configure. TARGET now defines the basename of the configuration
6672 file, startup script, manual page, etc. log_error_core() now reports
6673 the server binary name given by argv[0]. TARGET can now also be defined
6674 with --target=TARGET parameter passed to APACI configure.
6675 [Ralf Engelschall, Randy Terbush]
6677 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC

6698 and a redirect at the same time. [Lars Eilebrecht]
6700 *) Fallback to native compilers for IRIX-32 platform. It seems that
6701 a gcc 2.8.1 compiled apache is logging client addresses with all
6702 bits set (255.255.255.255). This is the second such problem caused
6703 by gcc 2.8.1 compiler. The first being broken semaphore locking.

6783 supported for the option argument: first BEGIN:foo which permutes module
6784 mod_foo with the begin of the module list, i.e. it `moves' the module to
6785 the begin of the list (gives it lowest priority). And second foo:END
6786 which permutes mod_foo with the end of the module list, i.e. it `moves'
6787 the module to the end of the list (gives it highest priority).

6858 Changes with Apache 1.3.3
6860 *) Added a complete implementation of the Expect header field as

6862 response when we already know the final status, which is mighty
6863 useful for PUT responses that result in 302 or 401. [Roy Fielding]
6865 *) Remove extra trailing whitespace from the getline results as part
6866 of the protocol processing, which is extra nice because it works
6867 between continuation lines, is almost no cost in the normal case
6868 of no extra whitespace, and saves memory. [Roy Fielding]
6870 *) Added new HTTP status codes and default response bodies from the
6871 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
6872 HTTP Extension Framework (510) specifications. Did not add the
6873 WebDAV 424 and 425 codes because they are bogus. We don't use any
6874 of these codes yet, but they are now available to 3rd-party modules.

6990 You now must define a BS2000Account name for the server User.
6991 This has fewer security implications than the old approach.
6994 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
6995 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
6996 platform to make the braindead HPUX linker happy. Notice, for the module
6997 DSOs we don't have to use this, because these are loaded manually (and

7009 *) Make PrintPath work generically instead of having one version
7010 strictly for OS/2. [Jim Jagielski, Brian Havard]
7012 *) Fix the recently introduced C header file checking: We now use the C
7013 pre-processor pass only (and no longer the complete compiler pass) to
7014 determine whether a C header file exists or not. Because only this way
7015 we're safe against inter-header dependencies (which caused horrible
7016 portability problems). The only drawback is that we now have a CPP
7017 configuration variable which has to be determined first (we do a similar
7018 approach as GNU Autoconf does here). When all fails the user still has
7019 the possibility to override it manually via APACI or src/Configuration.
7020 As a fallback for the header check itself we can directly check the
7021 existance of the file under /usr/include, too.

7061 (instead it directly passes through the message to be formatted to the
7062 real internal formatting function). [Ralf S. Engelschall] PR#2941
7064 *) Allow "Include" directives anywhere in the server config
7065 files (but not .htaccess files). [Ken Coar] PR#2727
7067 *) The proxy was refusing to serve CONNECT requests except to
7068 port 443 (https://) and 563 (snews://). The new AllowCONNECT
7069 directive allows the configuration of the ports to which a
7070 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
7072 *) mod_expires will now act on content that is not sent from a file
7073 on disk. Previously it would never add an Expires: header to
7074 any response that did not come from a file on disk; the only
7075 case where it still doesn't (and can't) add one for that type of
7076 content is if you are using a modification date based setting.
7077 [Marc Slemko, Paul Phillips <paulp@go2net.com>]

7080 that lead to a "500 Server Error" condition now provide explanatory
7081 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
7084 *) Add NameWidth keyword to IndexOptions directive so that the

7088 *) Recognize lowercase _and_ uppercase `uname' results under

7091 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
7092 a common problem of (mis-administrated?) IIS servers, make the apache
7093 proxy immune to these errors (and ignore the duplicates, but log
7094 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
7096 *) The <IfModule and <IfDefine block starting directives now only
7097 allow exactly one argument. Previously, the optional negation
7098 character '!' could be separated by whitespace without a syntax
7099 error being reported, albeit defeating the IfModule functionality
7100 (enclosed directives would ALWAYS be executed). By using the
7101 stricter syntax, these hard-to-track errors can be avoided.
7104 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
7105 cause the standalone FancyIndexing directive to logically OR
7106 into any existing IndexOptions settings rather than wiping
7107 them out. [Ken Coar]
7109 *) Changes in ftp proxy: make URL parsing simpler by using the
7111 + Add display of the "current directory" in cases where it's
7112 different from the supplied path (e.g., ftp://user@host/ lives
7113 in /home/user, not in /, therefore clicking on "../" in the
7114 starting directory might send us to /home/).
7115 + When ftp login fails, (esp. when a user name was part of the
7116 URL already), we now return [401 Unauthorized ] to allow the
7117 browser to pop up an authorization dialog. This makes passwords
7118 slightly less visible (they don't appear in the regular log files)
7119 and implements a functionality that other www proxy servers
7123 *) Triggered by the recent "Via:" header changes, the proxy module would
7124 dump core for replies with invalid headers (e.g., duplicate
7125 "HTTP/1.0 200 OK" lines). These errors are now logged and the
7126 core dump is avoided. Also, broken replies are not cached.

7168 *) Make the proxy generate and understand Via: headers
7171 *) Change the proxy to use tables instead of array_headers for
7172 the header lines. [Martin Kraemer]
7174 *) Make sure the config.status file is not overridden when just
7175 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
7177 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
7178 provide a way to trace API changes that add functionality but do
7179 not create a compatibility issue for precompiled modules, etc.
7180 See include/ap_mmn.h for more details. [Randy Terbush]
7182 *) Fix suexec installation under `make install root=xxx' situation.
7183 [Ralf S. Engelschall]
7185 *) Extend the output of the -V switch to include the paths of all
7186 compiled-in configuration files, if they were overridden at
7187 compile time, for least astonishment of the user.
7190 *) When READing a request in ExtendedStatus mode, the "old"
7191 vhost, request and client information is not displayed.
7194 *) STATUS is no longer available. Full status information now
7195 run-time configurable using the ExtendedStatus directive.
7198 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
7199 cpu time attacks) in header parsing. Add ap_overlap_tables(),
7200 a function which can be used to perform bulk update operations
7201 on tables in a more efficient manner. CAN-1999-1199 (cve.mitre.org)
7204 *) SECURITY: Added compile-time and configurable limits for
7205 various aspects of reading a client request to avoid some simple
7206 denial of service attacks, including limits on maximum request-line
7207 size (LimitRequestLine), number of header fields (LimitRequestFields),
7208 and size of any one header field (LimitRequestFieldsize). Also added
7209 a configurable directive LimitRequestBody for limiting the size of the
7210 request message body. [Roy Fielding]
7212 *) Make status module aware of DNS and logging states, even if
7213 STATUS not defined. [Jim Jagielski]
7215 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
7217 *) Enhance mod_speling so that CheckSpelling can be used in
7218 <Directory> containers and .htaccess files. [Ken Coar]
7220 *) API: new ap_custom_response() function for hooking into the
7221 ErrorDocument mechanism at runtime [Doug MacEachern]
7223 *) API: new ap_uuencode() function [Doug MacEachern]
7225 *) API: scan_script_header_err_core() now "public" and renamed
7226 ap_scan_script_header_err_core() [Doug MacEachern]
7228 *) The 'status' module will now show the process pid's and their
7229 state even without full STATUS accounting. [Jim Jagielski]
7231 *) Restore the client IP address to the error log messages, this
7232 was lost during the transition from 1.2 to 1.3. Add a new
7233 function ap_log_rerror() which takes a request_rec * and
7234 formats it appropriately. [Dean Gaudet] PR#2661
7236 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
7237 whitespace in input lines -- including within quoted strings.
7239 but leading and trailing whitespace should continue to be
7240 stripped [Martin Kraemer]
7242 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
7243 the ugly use of an env. variable and use command-line args for
7244 alternate $PATH. Make more like advanced 'type's as well.
7247 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
7248 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
7249 <alain.st-denis@ec.gc.ca>] PR#2736
7251 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
7253 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
7254 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
7255 directory was renamed to src/os/os2/ for consistency.
7256 [Brian Havard, Ralf S. Engelschall]
7258 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
7259 files (here modules) against other DSO files (here shared libraries).
7260 This is done by determining a subset of LIBS which can be safely used for
7261 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
7262 disabled for all platforms to avoid problems with this (experimental)
7263 rule. But we provide it now for those people how ran into problems and
7264 want to came out by forcing linking against DSOs.
7265 [Ralf S. Engelschall] PR#2587
7267 *) Fix suEXEC start message: Has to be of `notice' level to really get
7268 printed together with the standard startup message because the `notice'
7269 level is handled special inside ap_log_error() for startup messages.
7270 [Ralf S. Engelschall] PR#2761 PR#2761 PR#2765
7272 *) Add correct `model' MIME types from RFC2077 to mime.types file.
7273 [Ralf S. Engelschall] PR#2732
7275 *) Fixed examples in mod_rewrite.html document.
7276 [Youichirou Koga <y-koga@jp.FreeBSD.org>, Ralf S. Engelschall] PR#2756
7278 *) Allow ap_read_request errors to propagate through the normal request
7279 handling loop so that the connection can be properly closed with
7280 lingering_close, thus avoiding a potential TCP reset that would
7281 cause the client to miss the HTTP error response. [Roy Fielding]
7283 *) One more portability fix for APACI shadow tree support: Swap order of awk
7284 and sed in top-level configure script to avoid sed fails on some
7285 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
7286 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729
7288 *) PORT: NEC EWS4800 support.
7289 [MATSUURA Takanori <t-matsuu@protein.osaka-u.ac.jp>]
7291 *) Fix a segfault in the proxy on OS/2. [Brian Havard]
7293 *) Fix Win32 part of ap_spawn_child() by providing a reasonable child_info
7294 structure instead of just NULL. This fixes at least the RewriteMap
7295 programs under Win32. [Marco De Michele <mdemichele@tin.it>] PR#2483
7297 *) Add workaround to top-level `configure' script for brain dead
7298 `echo' commands which interpet escape sequences per default.
7299 [Ralf S. Engelschall] PR#2654
7301 *) Make sure that the path to the Perl interpreter is correctly
7302 adjusted under `make install' also for the printenv CGI script.
7303 [Ralf S. Engelschall] PR#2595
7305 *) Update the mod_rewrite.html document to correctly reflect the situation
7306 of the `proxy' (`[P]') feature. [Ralf S. Engelschall] PR#2679
7308 *) Fix `install-includes' sub-target of `install' target in top-level
7309 Makefile.tmpl: The umask+cp approach didn't work as expected (especially
7310 for users which extracted the distribution under 'umask 077'), so replace
7311 it by an explicit cp+chmod approach.
7312 [Richard Lloyd, Curt Sampson, Ralf S. Engelschall] PR#2656 PR#2626
7314 *) Fix `distclean' and `clean' targets in src/Makefile.tmpl to have same
7315 behavior and to cleanup correctly even under enabled SHARED_CORE rule.
7316 [Ralf S. Engelschall]
7318 *) Use a more straight forward and thus less problematic Sed command in
7319 src/helper/mkdir.sh script. [Ralf S. Engelschall]
7321 *) Make sure the `configure' scripts doesn't fail when trying to guess the
7322 domainname of the machine and there are multiple `domainname' and
7323 `search' entries in /etc/resolv.conf.
7324 [Ralf S. Engelschall] PR#2710
7326 *) Add note about the SHARED_CORE requirement on some platforms also to the
7327 INSTALL file because a lot of users don't read htdocs/manual/dso.html
7328 first. [Ralf S. Engelschall] PR#2701
7330 *) Fix document "hyperlink" for dso.html in src/Configuration.tmpl
7331 [Knut A.Syed <Knut.Syed@nhh.no>] PR#2674
7333 *) Modify mod_rewrite to update the Vary response field if the URL rewriting
7334 engine does any manipulations or decisions based upon request fields.
7337 *) Document the special APACI behavior for installation paths where
7338 ``/apache'' is appended to paths under some (well defined, of course)
7339 situations to prevent pollution of system locations with Apache files.
7340 [Ralf S. Engelschall] PR#2660
7342 *) Fixed problem with buffered response message not being sent for
7343 the read_request error conditions of URI-too-long (414) and
7344 malformed header fields (400). [Roy Fielding] PR#2646
7346 *) Add support for the Max-Forwards: header line required by RFC2068 for
7347 the TRACE method. This allows apache to TRACE along a chain of proxies
7348 up to a predetermined depth. [Martin Kraemer]
7350 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled
7351 (compilers complained) and the .so.V.R.P filename extension was adjusted
7352 to correctly reflect the 1.3.2 version.
7353 [Ralf S. Engelschall] PR#2644
7355 *) SECURITY: Plug "..." and other canonicalization holes under OS/2.
7358 *) PORT: implement serialized accepts for OS/2. [Brian Havard]
7360 *) mod_include had problems with the fsize and flastmod directives
7361 under WIN32. Fix also avoids the minor security hole of using
7362 ".." paths for fsize and flastmod.
7363 [Manoj Kasichainula <manojk@raleigh.ibm.com>] PR#2355
7365 *) Fixed some Makefile dependency problems. [Dean Gaudet]
7367 Changes with Apache 1.3.1
7369 *) Disable the incorrect entry for application/msword in the
7370 mod_mime_magic "magic" file because it also matches other Office
7371 documents. [Ralf S. Engelschall] PR#2608
7373 *) Fix broken RANLIB handling in src/Configure (the entry from
7374 src/Configuration.tmpl was ignored) and additionally force RANLIB to
7375 /bin/true under HP/UX where ranlib exists but is deprecated.
7376 [Ralf S. Engelschall] PR#2627
7378 *) 'apachectl status' failed on some systems.
7379 [Steve VanDevender <stevev@darkwing.uoregon.edu>, Lars Eilebrecht] PR#2613
7381 *) Add new flags for ap_unparse_uri_components() to make it generate
7382 the scheme://sitepart string only, or to omit the query string.
7385 *) WIN32: Canonicalize ServerRoot before checking to see if it
7386 is a valid directory. The failure to do this caused certain
7387 ServerRoot settings (eg. "ServerRoot /apache") to be improperly
7388 rejected. [Marc Slemko]
7390 *) Global renaming of C header files to both get rid of conflicts with third
7391 party packages and to again reach consistency:
7392 1. conf.h -> ap_config.h
7393 2. conf_auto.h -> ap_config_auto.h \ these are now merged
7394 3. ap_config.h -> ap_config_auto.h / in the config process
7395 4. compat.h -> ap_compat.h
7396 5. apctype.h -> ap_ctype.h
7397 Backward compatibility files for conf.h and compat.h were created.
7399 *) mod_mmap_static will no longer take action on requests unless at
7400 least one "mmapfile" directive is present in the configuration.
7401 This experimental module has to do some black magic to operate
7402 inside the current API and thus creates side-effects for other
7403 modules under some circumstances.
7404 [Ralf S. Engelschall]
7406 *) Add conservative ticks around more egrep arguments in top-level configure
7407 to avoid problems under brain-dead platforms like Digital UNIX (OSF1).
7408 [Ralf S. Engelschall] PR#2596
7410 *) mod_rewrite created RewriteLock files under the UID of the parent
7411 process, thus the child processes had no write access to the files.
7412 Now a chown() is done on the file to the uid of the children,
7413 if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341
7415 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
7416 TestCompile) instead of defining them manually in conf.h based on less
7417 accurate platform definitions. This way we no longer have to fiddle with
7418 OS-type and/or OS-version identifiers to discover whether a system header
7419 file exists or not. Instead we now directly check for the existence of
7420 those esoteric ones.

7424 *) mod_setenvif (BrowserMatch* and friends) will now match a missing
7425 field with "^$". [Ken Coar]
7427 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
7428 modules to load their own modules dynamically. This improves mod_perl
7429 and mod_php3 when these modules are loaded dynamically into Apache.
7432 *) Cache a proxied request in the event that the client cancels the
7433 transfer, provided that the configured percentage of the file has
7434 already been transfered. It works for HTTP transfers only. The
7435 new configuration directive is called CacheForceCompletion.

7439 required by HTML 3.2 and later) to mod_mime_magic's conf/magic.

7443 Signals suck. [Dean Gaudet]
7445 *) suexec's error messages have been clarified a little bit. [Ken Coar]
7447 *) Clean up some, but perhaps not all, 8-bit character set problems
7448 with config file parsing, and URL parsing. We now define
7449 ap_isdigit(), ap_isupper(), ... which cast to an (unsigned char).
7450 This should work on most modern unixes.
7451 [Dean Gaudet] PR#800, 2282, 2553 (and others)

7457 *) Add Dynamic Shared Object (DSO) support for SCO5 (OpenServer 5.0.x).
7458 [Ronald Record <rr@sco.com>] PR#2533
7460 *) The APACI libexecdir was not extended with an "apache/" subdir
7461 if the installation prefix didn't already contain "apache", but
7462 it should be because the DSO files are Apache-specific. Now
7463 libexecdir is treated the same way sysconfdir, datadir, localstatedir
7464 and includedir are already treated.
7465 [Charles Levert <charles@comm.polymtl.ca>] PR#2551
7467 *) The <Limit> parsing routine was incorrectly treating methods as
7468 case-insensitive. [Ken Coar]

7471 the connection. ap_bflush() misdiagnosed a failure as a success.
7474 *) add support for #perl arg interpolation in mod_include
7477 *) API: Name changes of table_elts to ap_table_elts, is_table_empty
7478 to ap_is_table_empty and bgetflag to ap_bgetflag. [Ben Laurie]

7484 used instead of "$PERL" which contains the correctly determined Perl
7485 interpreter (important for instance on systems where "perl" and "perl5"
7486 exists, like BSDI or FreeBSD, etc).
7487 [Ralf S. Engelschall] PR#2505
7489 *) Move the initial suEXEC-related startup message from plain
7490 fprintf()/stderr to a delayed ap_log_error()-based one to avoid problems
7491 when Apache is started from inetd (instead of standalone). Under this
7492 situation startup messages on stderr lead to problems (the line is sent
7493 to the client in front of the requested document).

7499 *) WIN32: Don't collapse multiple slashes in PATH_INFO.
7500 [Ben Laurie, Bill Stoddard <wgstodda@us.ibm.com>] PR#2274
7502 *) WIN32 SECURITY: Eliminate trailing "."s in path components. These are
7503 ignored by the Windows filesystem, and so can be used to bypass security.
7504 [Ben Laurie, Alexei Kosut].
7506 *) We now attempt to dump core when we get SIGILL. [Jim Jagielski]
7508 *) PORT: remove broken test for MAP_FILE in http_main.c.
7509 [Wilfredo Sanchez <wsanchez@apple.com>]
7511 *) PORT: Change support/apachectl to use "kill -0 $pid" to test if the
7512 httpd is running. This should be more portable than figuring out
7513 which of three dozen different versions of "ps" are installed.
7516 *) WIN32: If we can't figure out how to execute a file in a script
7517 directory, bail out of the request with an error message. [W G Stoddard]
7519 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
7520 these are treated by Win32 as if they are ".." but are not detected by
7521 other machinery within Apache. This is something of a kludge but
7522 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
7524 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
7525 pools and thus pollutes libap (until the pool stuff is moved there).
7528 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
7529 but case-insensitive platforms). New #define for this added to conf.h
7530 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455
7532 *) Enable DSO support for OpenBSD in general, not only for 2.x, because it
7533 also works for OpenBSD 1.x. [Ralf S. Engelschall]
7535 *) PORT: Fix compilation problem on ARM Linux.
7536 [Sam Kington <sam@illuminated.co.uk>] PR#2443
7538 *) Let APACI's configure script determine some configuration parameters
7539 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
7540 remove some of the classical hurdles for new users when setting up
7541 Apache. This is done per default because it is useful for the average
7542 user. Package authors can use the --without-confadjust option to disable
7543 these configuration adjustments.
7544 [Ralf S. Engelschall]
7546 *) Added an EXTRA_DEPS configuration parameter which can be used
7547 to add an extra Makefile dependency for the httpd target, for instance
7548 to external third-party libraries, etc.
7549 [Ralf S. Engelschall]
7551 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
7552 as <IfModule>..</IfModule> sections) which can be used to skip or process
7553 contained commands dependend of ``-D PARAMETER'' options on the command
7554 line. This can be used to achieve logical conditions like <IfDefine
7555 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
7556 and thus especially can be used for conditionally loading DSO-based
7557 modules via LoadModule, etc. [Ralf S. Engelschall]
7559 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
7561 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
7563 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
7564 truncated which forced following HTTP headers to be data in the HTTP
7565 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
7568 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
7569 in top-level configure script to avoid sed fails on some platforms (for
7570 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
7571 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
7573 *) Improve performance of directory listings (mod_autoindex) by comparing
7574 integer keys (last-modified and size) as integers rather than converting
7575 them to strings first. Also use a set of explicit byte tests rather
7576 than strcmp() to check for parent directory-ness of an entry. Oh, and
7577 make sure the parent directory (if displayed) is *always* listed first
7578 regardless of the sort key. Overall performance winnage should be good
7579 in CPU time, instruction cache, and memory usage, particularly for large
7580 directories. [Ken Coar]
7582 *) Add a tiny but useful goody to APACI's configure script: The generation
7583 of a config.status script (as GNU Autoconf does) which remembers the used
7584 configure command and hence can be used to restore the configuration by
7585 just re-running this script or for remembering the configuration between
7587 [Ralf S. Engelschall]
7589 *) Add httpd -t (test) option for running configuration syntax tests only.
7590 If something is broken it complains and exits with a return code
7591 non-equal to 0. This can be used manually by the user to check the Apache
7592 configuration after editing and is also automatically used by apachectl
7593 on (graceful) restart command to make sure Apache doesn't die on restarts
7594 because of a configuration which is now broken since the last (re)start.
7595 This way `apachectl restart' can be used inside cronjobs without having
7596 to expect Apache to be falling down. Additionally the httpd -t can be run
7597 via `apachectl configtest'.

7670 solved by another helper script findprg.sh which searches for Perl and
7671 Awk like PrintPath but _via different names_.

7687 *) Fix recently introduced Win32 child spawning code in mod_rewrite.c which
7688 was broken because of invalid ap_pstrcat() -> strcat() transformation.
7689 [Ralf S. Engelschall]
7691 *) Proxy Cache Fixes: account for directory sizes, fork off garbage collection
7692 to continue in background, use predefined types (off_t, size_t, time_t),
7693 log the current cache usage percentage at LogLevel debug
7694 [Martin Kraemer, based on discussion between Dean Gaudet & Dirk vanGulik]
7696 Changes with Apache 1.3.0
7698 *) Using a type map file as a custom error document was not possible.
7699 [Lars Eilebrecht] PR#1031
7701 *) Avoid problems with braindead Awks by additionally searching for gawk
7702 and nawk in APACI's configure script.
7703 [Dave Dykstra <dwd@bell-labs.com>, Ralf S. Engelschall] PR#2319
7705 *) Rename md5.h to ap_md5.h to avoid conflicts with native MD5 on
7706 some systems. [Randy Terbush]
7708 *) Change usage of perror()+fprintf(stderr,...) in mod_rewrite to
7709 more proper ap_log_error() variants.
7710 [Ralf S. Engelschall]
7712 *) Make sure the argument for the --add-module option to APACI's configure
7713 script is of type [path/to/]mod_xxx.c because all calculations inside
7714 configure and src/Configure depend on this.
7715 [Ralf S. Engelschall] PR#2307
7717 *) Changes usage of perror/fprintf to stderr to more proper ap_log_error
7718 in mod_mime, mod_log_referer, mod_log_agent, and mod_log_config.
7721 *) Various OS/2 cleanups ["Brian Havard" <brianh@kheldar.apana.org.au>]
7723 *) PORT: QNX needed a #include <sys/mman.h>; and now it uses flock
7724 serialized accept to handle multiple sockets.
7725 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2295, 2296
7727 *) Have NT properly set the directory for CGI scripts
7728 (& other spawned children)
7729 [W G Stoddard <wgstodda@us.ibm.com>]
7731 *) Propagate environment to CGI scripts correctly in Win32.
7732 [W G Stoddard <wgstodda@us.ibm.com>] PR#2294
7734 *) Some symbol renaming:
7735 ap_spawn_child_err became ap_spawn_child
7736 ap_spawn_child_err_buff became ap_bspawn_child
7737 spawn_child was obsoleted and moved to compat.h
7740 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
7741 programs: ap_spawn_child_err() is used and the Win32 case now uses
7742 CreateProcess() instead of a low-level execl() (which caused problems in
7743 the past under Win32).
7744 [Ralf S. Engelschall]
7746 *) A few cosmetics and trivial enhancements to APXS to make the
7747 generated Makefile more user friendly. [Ralf S. Engelschall]
7749 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
7750 was updated to use the normal apache error processing, thereby allowing
7751 proxy errors to be treated by ErrorDocument's as well. For this
7752 purpose, a new module-to-core communication variable "error-notes"
7753 was introduced; the proxy (and possibly other modules) communicates
7754 its error text using this variable. Its content is copied to a new
7755 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
7756 The old proxy special error routine ap_proxy_log_uerror()
7757 was replaced by regular ap_log_error() calls, many messages were made
7759 [Martin Kraemer] PR#494, 1259
7761 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
7764 *) Transform the configure message "You need root privileges for suEXEC"
7765 from a fatal error into a (more friendly) warning because the building
7766 ("make") of Apache we can allow, of course. Root privileges are needed
7767 only for the installation step ("make install"). So make sure the
7768 user is aware of this fact but let him proceed as long as he can.
7769 [Ralf S. Engelschall] PR#2288
7771 *) Renamed three more functions to common ap_ prefix which we missed at the
7772 Big Symbol Renaming because they're #defines and not real C functions:
7773 is_default_port(), default_port(), http_method().
7774 [Ralf S. Engelschall]
7776 *) A zero-length name after a $ in an SSI document should cause
7777 just the $ to be in the expansion. This was broken during the
7778 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
7780 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
7781 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252

7784 used under AIX) because of recent changes to function names.
7785 [Ralf S. Engelschall]
7787 Changes with Apache 1.3b7
7789 *) Make sure a MIME-type can be forced via a RewriteRule even when no
7790 substitution takes place, for instance via the following rule:
7791 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
7792 requested by users in the past to force a single script without a .cgi
7793 extension and outside any cgi-bin dirs to be executed as a CGI program.

7796 *) A fix for protocol issues surrounding 400, 408, and
7797 414 responses. [Ed Korthof]

7801 *) Fix discrepancy in proxy_ftp.c which was causing failures when
7802 trying to connect to certain ftpd's, such as anonftpd.
7803 [Rick Ohnemus <rick@ecompcon.com>]
7805 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
7806 logfile instead of fiddling around itself with child spawning stuff.
7807 [Ralf S. Engelschall]
7809 *) Made RefererIgnore case-insensitive.
7811 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
7814 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
7815 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
7818 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
7820 *) Fix support script `dbmmanage': It was unable to handle some sort
7821 of passwords, especially passwords with "0" chars.
7822 [Ralf S. Engelschall] PR#2242
7824 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
7825 [Ben Laurie] PR#2238
7827 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
7828 library), so CGI handling has been changed to use Win32 native handles
7829 instead of C file descriptors.
7830 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
7832 *) The proxy cache would store an incorrect content-length in the cached
7833 file copy after a cache update. That resulted in repeated fetching
7834 of the original copy instead of using the cached copy.
7835 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
7837 *) The Makefiles assumed that DSO files are build via $(LD). This
7838 is broken for two reasons: First we never defined at least LD=ld
7839 somewhere to make sure this works (it was silently assumed that most Make
7840 provide a built-in LD definition - ARGL!) and second using the generic LD
7841 variable is not the truth. Instead a special variable named LD_SHLIB is
7842 reasonable because although "ld" is usually the default, the command for
7843 building DSO files can be "libtool" or even "cc" on some systems.
7844 [Ralf S. Engelschall]
7846 *) Replace the AddVersionPlatform directive with ServerTokens which
7847 provides for more control over the format of the Server:
7848 header line. SERVER_SUBVERSION is no longer supported;
7849 all module should use the ap_add_version_component()
7850 API function instead. [Jim Jagielski]
7852 *) Support for the NCR MP/RAS 3.0
7853 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
7855 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
7856 not retrieved in src/Configure and thus was not useable.
7857 [Ralf S. Engelschall]
7859 *) Various Makefile consistency cleanups:
7860 - make OSDIR also automatically be relative to src/ like INCDIR
7861 - SUBDIRS is now generated in src/Makefile only and not in
7862 Makefile.config because it is a local define for this location.
7863 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
7864 any Makefile but make sure that at least the "-K inline" is kept in
7866 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
7867 - updated the dependencies theirself
7868 - removed not existing SHLIB variable from "clean" targets
7869 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
7870 already exists and OBJS_PIC are also just plain objects and have not
7871 directly to do with "shared" things. The only difference is that they
7872 contain PIC. So OBJS_PIC is the more canonical name.
7873 - Updated the Makefile-dependency lines for OBJS_PIC
7874 - Removed the Makefile-dependency line in Configure to avoid double
7876 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
7877 of xxx.lo as GNU libtool does with its PIC objects
7878 - reduce local complexity in modules Makefile.tmpl by moving the last
7879 existing target "depend" to the generation section in Configure, too.
7880 - removed the historical $(SPACER) which was used in the past together
7881 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
7882 is no longer needed.
7883 - force the build and run of the gen_xxx programs under main/ as the
7884 first step before building the objects because it looks cleaner
7885 [Ralf S. Engelschall]
7887 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
7890 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
7893 *) WIN32: Don't force ISAPI headers to finish with \n.
7894 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
7896 *) When opening "configuration" files (like httpd.conf, htaccess
7897 and htpasswd), Apache will not allow them to be non-/dev/null
7898 device files. This closes a DoS hole. At the same time,
7899 we use ap_pfopen to open these files to handle timeouts.
7900 [Jim Jagielski, Martin Kraemer]
7902 *) Apache will now log the reason its httpd children exit if they exit
7903 due to an unexpected signal. (It requires a new porting define,
7904 SYS_SIGLIST, which if defined should point to a list of text
7905 descriptions of the signals available. See PORTING.) [Dean Gaudet]
7907 *) WIN32: chdir() doesn't make sense in a multithreaded environment
7908 like WIN32. Before, Win32 CGI's could have had sporadic failures
7909 if a chdir call from one thread was made between another chdir call
7910 and a spawn in another thread. So, for now don't chdir for CGI scripts
7911 in WIN32. The current CGI "spec" is unclear as to whether it's
7912 necessary. Long-term fix is to either serialize the chdir/spawn combo
7913 or use WIN32 native calls to spawn a process. This temp fix was
7914 necessary to remove this as a showstopper for 1.3's release.
7917 *) Cleanup the suEXEC support in APACI and make it more safe:
7918 1. Add big fat hint in INSTALL about risks and to read the
7919 htdocs/manual/suexec.html document before using the suexec-related
7921 2. Make sure the user has at least provided one --suexec-xxxx option
7922 (specifies suEXEC parameters) in addition to --enable-suexec option.
7923 If only --enable-suexec is given APACI stops with a hint to INSTALL
7924 and htdocs/manual/suexec.html documents.
7925 3. Provide two additional --suexec-xxxx options to make the suEXEC
7926 configuration complete (especially for package maintainers who else
7927 had to patch the source tree) by providing ways to configure minimal
7928 UID/GID and safe PATH, too.
7929 [Ralf S. Engelschall]
7931 *) Cleanup of the `configure --shadow' process:
7932 - make sure the configure script creates its temporary files in the
7933 shadow tree to avoid conflicts with parallel configure runs
7934 - removed unnecessary option "-r" from "rm" call for Makefiles
7935 - make sure the configure scripts creates the shadow-wrapper Makefile
7936 only when no shadow trees already exists
7937 - make sure "make distclean" removes the shadow-wrapper Makefile but only
7938 when no more shadow trees exists
7939 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
7940 as fast (in the past it needed 70sec, now it runs just 38sec)
7941 - make sure CVS does not complain about the created files
7942 Makefille.<gnutriple> and directories src.<gnutriple>
7943 [Ralf S. Engelschall]
7945 *) Added the ap_add_version_component() API routine and the
7946 AddVersionPlatform core directive. The first allows modules to
7947 declare themselves in the Server response header field value,
7948 augmenting the SERVER_SUBVERSION define in the Configuration file
7949 with run-time settings (more useful in a loadable-module environment).
7950 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
7951 into the server version string. [Ken Coar] PR#2056
7953 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
7956 *) Emit the "Accept-Range" header for the default handler.
7957 [Brian Behlendorf] PR#1464
7959 *) Add a note to httpd.conf-dist that apache will on some systems fail
7960 to start when the Group # is set to a negative or large positive value.
7963 *) Make sure the module execution order is correct even when some modules
7964 are loaded under runtime (`LoadModule') via the DSO mechanism:
7965 1. The list of loaded modules is now a dynamically allocated one
7966 and not the original statically list from modules.c
7967 2. The loaded modules are now correctly setup by LoadModule for
7968 later use by the AddModule command.
7969 3. When the DSO mechanism for modules is used APACI's `install'
7970 target now enables all created `LoadModule' lines per default because
7971 this is both already expected by the user _and_ needed to avoid
7972 confusion with the next point and reduces the Makefile.tmpl complexity
7973 4. When the DSO mechanism for modules is used, APACI's `install'
7974 target now additionally makes sure the module list is reconstructed
7975 via a complete `ClearModuleList+AddModule...' entry.
7976 5. The support tool `apxs' now also makes sure an AddModule command
7977 is added in addition to the LoadModule command.
7978 6. The modules.c generation was extended to now contain two
7979 comments to make sure no one is confused by the confusing terminology
7980 of loading/linking (we use load=link+load & link=activate instead of
7981 the obvious load=activate & link=link :-( )
7982 This way now there is no longer a difference under execution time between
7983 statically and dynamically linked modules.
7984 [Ralf S. Engelschall]
7986 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
7987 Big Symbol Renaming. [Ralf S. Engelschall]
7989 *) Add a comment to mod_example.c showing the format of a FLAG command
7992 *) Standardized the time format in mod_status to match that of other
7993 places in the code (e.g. DATE_GMT). PR#1551
7995 *) Fix handling of %Z in timefmt strings for those platforms with no time
7996 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
7999 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
8000 feature compatible with 'UseCanonicalName off' by changing
8001 r->server->server_hostname to ap_get_server_name(). And I changed some
8002 functions which use r->server->port to use ap_get_server_port() instead,
8003 because if there's no Port directive in the config r->server->port is 0.
8006 *) get/set_module_config are trivial enough to be better off inline. Worth
8007 1.5% performance boost. [Dean Gaudet]
8009 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
8010 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
8013 *) [BS2000 security] BS2000 needs an extra authentication to initialize
8014 the task environment to the unprivileged User id. Otherwise CGI scripts
8015 would have a way to gain super user access. [Martin Kraemer]
8017 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
8018 absolute path, only log base name of logging source as is done
8019 in unix. [Martin Kraemer]
8021 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
8022 the encoding type from the Accept-Encoding header (if it's there)
8023 and use it in the response, as that's probably what it'll be expecting.
8024 [Ronald.Tschalaer@psi.ch]
8026 *) Fix to mod_alias: translate_alias_redir is dealing with
8027 a URI, not a filename, so the check for drive letters for win32
8028 and emx is not necessary. [Dean Gaudet]
8030 *) WIN32: Allow .cmd as an executable extension.
8031 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
8033 *) Make Apache header files, and some variables, C++ friendly.
8034 [Michael Anderson's <mka@redes.int.com.mx>]
8036 *) Child processes can now "signal" (by exiting with a status
8037 of APEXIT_CHILDFATAL) the parent process to abort and
8038 shutdown the server if the error in the child process was
8039 fatal enough. [Jim Jagielski]
8041 *) mod_autoindex's find_itme() was sensitive to MIME type case.
8042 [Jim Jagielski] PR#2112
8044 *) Make sure the referer_log and agent_log entries in the default httpd.conf
8045 file are also adjusted for the actual relative installation paths.
8046 [Ralf S. Engelschall] PR#2175
8048 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
8050 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
8053 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
8054 Additionally the checks for finding the vendor DSO library were moved
8055 from mod_so.c to Configure because first it needs $PLAT etc. and second
8056 mod_so already uses an abstraction layer and does not fiddle with the
8057 vendor functions itself.
8058 [Jens-Uwe Mager, Ralf S. Engelschall]
8060 *) PORT: Some optimization defines for NetBSD
8061 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
8063 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
8064 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
8066 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
8067 AIX variants should work fine, too. Even AIX 3.x should work). This is
8068 accomplished by using the free DSO emulation code from Jens-Uwe Mager
8069 which we put into a os/unix/os-dso-aix.c file.
8070 [Ralf S. Engelschall]
8072 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
8073 that we should use NET_SIZE_T == int but the include files force size_t.
8074 [Ralf S. Engelschall]
8076 *) Fix two bugs in select() handling in http_main.c.
8079 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
8080 is unset (as it is in situations like timeouts) where it is unclear
8081 whether errno is set or not. [Martin Kraemer]
8083 *) Just having APACI's localstatedir is too general and not enough for most
8084 of the systems. 1.3b6 again required manual APACI patches by package
8085 maintainers from Red Hat and FreeBSD because for their filesystem layout a
8086 little bit more flexibility in configuring the paths is needed. Hence we
8087 provide three additional configure options (--runtimedir, --logfiledir,
8088 --proxycachedir) which now can be used for more granular adjustments if
8089 --localstatedir is not enough to fit the particular needs. As a nice
8090 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
8091 [Ralf S. Engelschall]
8093 *) Make the install root for "make install" in APACI's Makefile overrideable
8094 by package authors. This way we are even more friendly to package
8095 maintainers (especially Debian and Red Hat) who build for the real prefix
8096 via "configure --prefix=/<real>" but use a different local prefix via
8097 "make root=/tmp/apache install" for rolling the package without bristling
8098 the target location on their system.
8099 [Ralf S. Engelschall]
8101 *) Workaround sed limitations in APACI's configure script by now
8102 substituting in chunks of 50 commands (because for instance HPUX's vendor
8103 sed has a limit of max. 98 commands)
8104 [Ralf S. Engelschall] PR#2136
8106 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
8107 [Ralf S. Engelschall] PR#2140
8109 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
8110 RENAMING process because they are defined as pre-processor macros instead
8111 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
8112 [Ralf S. Engelschall]
8114 *) Workaround braindead AWK's when generating ap_config.h: The split() and
8115 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
8116 [Ralf S. Engelschall] PR#2139
8118 *) Various bugfixes and cleanups for the APACI configure script:
8119 o fix IFS handling for _nested_ situation
8120 o fix Perl interpreter search: take first one found instead of last one
8121 o fix DSO consistency check
8122 o print error messages to stderr instead of stdout
8123 o add install-quiet for --shadow situation to Makefile stub
8124 o reduce complexity by avoiding sed-hacks for rule and module list loops
8125 [Ralf S. Engelschall]
8127 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
8129 *) Make sure the input field separator (IFS) shell variable is explicitly
8130 initialized correctly before _every_ `for' loop and also restored after
8131 the loops. [Ralf S. Engelschall]
8133 *) Make sure that "make install" doesn't overwrite the `mime.types' and
8134 `magic' files from an existing Apache installation. Because people often
8135 customize these for own MIME and content types.
8136 [Ralf S. Engelschall]
8138 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
8139 [Peter Galbavy, Ralf S. Engelschall] PR#2109
8141 *) Fix the path to the ScoreBoardFile in the install-config target, too.
8142 [Ralf S. Engelschall] PR#2105
8144 *) Let "configure" clear out the users parameters (provided as shell
8145 variables) to avoid side-effects in "src/Configure" when the user
8146 exported them (which is not needed, but some users do it).
8147 [Ralf S. Engelschall] PR#2101
8149 *) Provide backward compatibility from some old src/Configuration.tmpl
8150 parameter names to the canonical Autoconf-style shell variable names. For
8151 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
8152 but a hint message is displayed. [Ralf S. Engelschall]

8155 CGI scripts from an existing Apache installation.
8156 [Ralf S. Engelschall, Jim Jagielski] PR#2084
8158 *) Make `configure --compat' more "compatible" by first
8159 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
8160 second by making sure the "avoid-bristling-suffix" /apache is not
8161 appended to sysconfdir, datadir, localstatedir and includedir when
8162 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
8164 *) NeXT required strdup() in support/logresolve.c
8165 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
8167 *) AIX required sys/select.h in support/ab.c

8170 *) Fix the path to the MimeMagicFile in the install-config target, too.
8171 [Ralf S. Engelschall] PR#2089
8173 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
8175 *) If you start apache with the -S command line option it will dump
8176 out the parsed vhost settings. This is useful for folks trying
8177 to figure out what is wrong with their vhost configuration.
8178 (Other dumps may be added in the future.) [Dean Gaudet]
8180 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
8181 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
8184 *) Because /usr/local/apache is the default prefix the ``configure
8185 --compat'' option no longer has to set prefix, again. This way the
8186 --compat option honors a leading --prefix option. [Lars Eilebrecht]
8188 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
8189 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
8190 to avoid "discard const" warnings. [Ralf S. Engelschall]
8192 *) If a specific handler is set for a file yet the request still
8193 ends up being handled by the default handler, log an error
8194 message before handling it. This catches things such as trying
8195 to use SSIs without mod_include enabled. [Marc Slemko]
8197 *) Fix error logging for the startup case where ap_log_error() still uses
8198 stderr as the target. Now the default log level is honored here, too.
8199 [Ralf S. Engelschall]
8201 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
8202 long" errors when generating the MODULES entry for src/Makefile
8203 [Ben Hyde, Ralf S. Engelschall]
8205 *) Make sure src/Configure doesn't complain about the old directory
8206 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
8208 Changes with Apache 1.3b6
8210 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
8212 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
8213 interface via the similar but proprietary HP/UX shl_xxx-style system
8214 calls. [Ralf S. Engelschall]
8216 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
8217 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
8218 Make. [Ralf S. Engelschall]
8220 *) ++++ THE BIG SYMBOL RENAMING ++++
8221 To avoid symbol clashes with third-party code compiled into the server,
8222 we globally applied the prefix "ap_" to the following classes of
8224 - Apache provided general functions (e.g., ap_cpystrn)
8225 - Public API functions (e.g., palloc, bgets)
8226 - Private functions which we can't make static (because of
8227 cross-object usage) but should be (e.g., new_connection)
8228 For backward source compatibility a new header file named compat.h was
8229 created which provides defines for the old symbol names and can be used
8230 by third-party module authors.
8233 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
8234 problem under SVR4 is that there is no command flag to force the linker
8235 to export the global symbols of the httpd executable therewith they are
8236 available to the DSO's. Instead of problematic hacks like creating a
8237 dummy.so file (containing dummy references to all global symbols) the
8238 httpd binary is linked against, we use a clean trick stolen from Perl 5:
8239 Placing the Apache core code itself into a DSO library named libhttpd.so.
8240 This way the global symbols _HAVE_ to be exported and thus are available
8241 to any manually loaded DSO's under runtime. To reduce the impact to the
8242 user to null we go even further and create a stub httpd executable which
8243 automatically keeps track of the DSO library loading itself and thus
8244 hides the complete mechanism from the user. Although the generation of
8245 this DSO library is automatically triggered for platforms which
8246 essentially need it (mostly all SVR4-derivates) it can be also enabled
8247 manually via the Rule SHARED_CORE. This can be interesting in the future
8248 where we perhaps exploit this libhttpd.so mechanism for providing nifty
8249 features like graceful upgrades, or whatever.
8250 [Ralf S. Engelschall, Martin Kraemer]
8252 *) Build the libraries before building the rest of the tools. [Ben Hyde]
8254 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
8255 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
8256 conventions while "clean" removes only stuff created by "all" targets,
8257 "distclean" additionally removes the stuff from the configuration
8258 process. This way "make distclean" (hence the name) provides a fresh
8259 source tree as it was for distribution.
8260 [Ralf S. Engelschall]
8262 *) Allow top-level (APACI) Makefile to break on build errors
8263 the same way the src/ subtree Makefiles breaks on them by replacing the
8264 initial APACI sed-subdir-display-kludge with a more clean
8265 variable-passing-solution: variable SDP can optionally hold the subdir
8266 prefix which is consistently used for displaying the subdir movement.
8267 This way even the top-level Makefile can stop correctly on errors as the
8268 user expects. [Ralf S. Engelschall]
8270 *) Fixed ordering of argument checks for RewriteBase directive.
8271 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
8273 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
8274 indicating that a module is being compiled for dynamic loading. Also
8275 remove #define IS_MODULE from modules and add SHARED_MODULE define
8276 to the mak/dsp files. [Alexei Kosut]
8278 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
8279 since we are now logging APLOG_WARNING by default. [Roy Fielding]
8281 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
8283 *) Add documentation file and src/Configuration.tmpl entry for the
8284 experimental mod_mmap_static module. Because although it is and marked as
8285 an experimental one it is distributed and thus should be documented and
8286 prepared for configuration the same way as all others modules.
8287 [Ralf S. Engelschall]
8289 *) Add query (-q) option to apxs support tool to be able to manually query
8290 specific settings from apxs. This is needed for instance when you
8291 manually want to access Apache's header files and you need to assemble
8292 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
8293 [Ralf S. Engelschall]
8295 *) Now src/Configure uses a fallback strategy for the shared object support
8296 on platforms where no explicit information is available: If a Perl
8297 installation exists we ask it about its shared object support and if it's
8298 the dlopen-style one we shamelessly guess the compiler and linker flags
8299 for creating shared objects from Perls knowledge. Of course, the user is
8300 warning about what we are doing and informed that he should send us
8301 the guessed flags when they work. [Ralf S. Engelschall]
8303 *) Provide APACI --without-support option to be able to disable the build
8304 and installation of the support tools from the src/support/ area.
8305 Although its useful to have these installed per default we should provide
8306 a way to compile and install without them for backward-compatibility.
8307 [Ralf S. Engelschall]
8309 *) Add of the new APache eXtenSion (apxs) support tool for building and
8310 installing modules into an _already installed_ Apache package through the
8311 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
8312 this approach actually doesn't need the Apache source tree. The
8313 (APACI-installed) server package is enough, because this now includes the
8314 Apache C header files (PREFIX/include) and the new APXS tool
8315 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
8316 module authors to build their Apache modules _OUTSIDE_ the Apache source
8317 tree while avoiding them to fiddle around with the totally platform
8318 dependend way of compiling DSO files. The tool supports all ranges of
8319 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
8320 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
8321 on-the-fly generate a minimalistic Makefile and sample module for the
8322 first step to provide both a quick success event and to demonstrate the
8323 APXS mechanism to module authors. [Ralf S. Engelschall]
8325 *) Fix core dumps in use of CONNECT in proxy.
8326 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
8328 *) Modify the log directives in httpd.conf-dist files to use CustomLog
8329 so that users have examples of how CustomLog can be used.
8332 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
8333 the Apache distribution tree. Until Apache 1.3 there was no real
8334 out-of-the-box batch-capable build and installation procedure for the
8335 complete Apache package. This is now provided by a top-level "configure"
8336 script and a corresponding top-level "Makefile.tmpl" file. The goal is
8337 to provide a GNU Autoconf-style frontend which is capable to both drive
8338 the old src/Configure stuff in batch and additionally installs the
8339 package with a GNU-conforming directory layout. Any options from the old
8340 configuration scheme are available plus a lot of new options for flexibly
8341 customizing Apache. [Ralf S. Engelschall]
8343 *) The floating point ap_snprintf code wasn't threadsafe.
8344 Had to remove the HAVE_CVT macro in order to do threadsafe
8345 calling of the ?cvt() floating point routines. [Dean Gaudet]
8347 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
8349 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
8350 [Jim Jagielski] PR#1901
8352 *) BUG: Configure was using TCC and CC inconsistently. Make sure
8353 Configure knows which CC we are using. [Jim Jagielski]
8355 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
8356 was defined in a parent directory. [Lars Eilebrecht]
8358 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
8359 a generic printf-style routine that can call arbitrary output
8360 routines. Use this to replace http_bprintf.c. Add new routines
8361 psprintf(), pvsprintf() which allocate the exact amount of memory
8362 required for a string from a pool. Use psprintf() to clean up
8363 various bits of code which used ap_snprintf()/pstrdup().
8366 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
8367 ap_snprintf() has different semantics and formatting codes than
8368 snprintf(). [Dean Gaudet]
8370 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
8371 is necessary on at least Solaris where the /etc/rc?.d scripts
8372 are run with these signals ignored, and "SIG_IGN" settings are
8373 maintained across exec().
8374 [Rein Tollevik <reint@sys.sol.no>] PR#2009
8376 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
8377 used instead of lstat() and thus this flag didn't work as expected.
8378 [Rein Tollevik <reint@sys.sol.no>] PR#2010
8380 *) Fix the proxy pass-through feature of mod_rewrite for the case of
8381 existing QUERY_STRING now that mod_proxy was recently changed because of
8382 the new URL parsing stuff. [Ralf S. Engelschall]
8384 *) A few changes to scoreboard definitions which helps gcc generate
8385 better code. [Dean Gaudet]
8387 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
8388 be a signed bitfield. So mark a few bitfields as signed to
8389 ensure correct code. [Dean Gaudet]
8391 *) The default for HostnameLookups was changed to Off, but there
8392 was a problem and it wasn't taking effect. [Dean Gaudet]
8394 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
8397 *) After a SIGHUP the listening sockets in the parent weren't
8398 properly marked for closure on fork().
8399 [Jürgen Keil <jk@tools.de>] PR#2000
8401 *) Allow %2F in two situations: 1) it is in the query part of the URI,
8402 therefore not exposed to %2F -> '/' translations and 2) the request
8403 is a proxy request, so we're not dealing with a local resource anyway.
8404 Without this, the proxy would fail to work for any URL's with
8405 %2f in them (occurs quite often in
8406 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
8408 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
8410 *) Make the shared object compilation command more portable by avoiding
8411 the direct combination of `-c' & `-o' which is not honored by some
8412 compilers like UnixWare's cc. [Ralf S. Engelschall]
8414 *) WIN32: the proxy was creating filenames missing the last four
8415 characters. While this normally doesn't stop anything from
8416 working, it can result in extra collisions.
8417 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
8419 *) Now mod_proxy uses the response string (in addition to the response status
8420 code) from the already used FTP SIZE command to setup the Content-Length
8421 header if available. [Ralf S. Engelschall] PR#1183
8423 *) Reanimated the (still undocumented) proxy receive buffer size directive:
8424 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
8425 name was really too generic, added documentation for this directive to
8426 the mod_proxy.html and corrected the hyperlink to it in the
8427 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
8429 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
8430 faster [Martin Kraemer]
8432 *) Make Configure die when you give it an unknown command switch.
8435 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
8436 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
8437 and per default compiled support programs have manual pages - just to
8438 document our stuff a little bit more and to be able to do really
8439 Unix-like installations ;-) [Ralf S. Engelschall]
8441 *) Major cleanups to the Configure script to make it and its generated
8442 Makefiles again readable and maintainable: add SRCDIR option, removed
8443 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
8444 generated sections, consequently added Makefile headers with inheritance
8445 information, added subdir movement messages for easier following where
8446 the build process currently stays (more verbose then standard Make, less
8447 verbose than GNU make), same style to comments in the Configure script,
8448 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
8450 *) Add the new ApacheBench program "ab" to src/support/: This is derived
8451 from the ZeusBench benchmarking program and can be used to determine the
8452 response performance of an Apache installation. This version is
8453 officially licensed with Zeus Technology, Ltd. See the license agreement
8454 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
8455 [Ralf S. Engelschall]
8457 *) API: Various core functions that are definately not part of the API
8458 have been made static, and a few have been marked API_EXPORT. Still
8459 more have been marked CORE_EXPORT and are not intended for general
8460 use by modules. [Doug MacEachern, Dean Gaudet]
8462 *) mod_proxy was not clearing the Proxy-Connection header from
8463 requests; now it does. This did not violate any spec, however
8464 causes poor interactions when you are talking to remote proxies.
8465 [Marc Slemko] PR#1741
8467 *) Various cleanups to the command line interface and manual pages.
8468 [Ralf S. Engelschall]
8470 *) cfg_getline() was not properly handling lines that did not end
8471 with a line termination character. [Marc Slemko] PR#1869, 1909
8473 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
8475 *) Clean up some undocumented behavior of mod_setenvif related to
8476 "merging" two SetEnvIf directives when they match the same header
8477 and regex. Document that mod_setenvif will perform comparisons in
8478 the order they appear in the config file. Optimize mod_setenvif by
8479 doing more work at config time rather than at runtime.
8482 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
8483 to allow for modules to overrule them and to reduce redefinition
8484 warnings [Jim Jagielski]
8486 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
8489 *) Making the hard-coded cross-module function call mime_find_ct() (from
8490 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
8491 checking is really called even for proxy requests except for URLs with
8492 HTTP schemes (because there we can optimize by not running the type
8493 checking hooks due to the fact that the proxy gets the MIME Content-type
8494 from the remote host later). This change cleans up mod_mime by removing
8495 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
8496 especially unbundles mod_proxy and mod_mime. This way they both now can
8497 be compiled as shared objects and are no longer tied together.
8498 [Ralf S. Engelschall]
8500 *) util.c cleanup and speedup. [Dean Gaudet]
8502 *) API: Clarification, pstrndup() will always copy n bytes of the source
8503 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
8505 *) Mark module command_rec and handler_rec structures const so that they
8506 end up in the read-only data section (and are friendlier to systems
8507 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
8509 *) Add check to the "Port" directive to make sure the specified
8510 port is in the appropriate range. [Ben Hyde]
8512 *) Performance improvements to invoke_handler().
8513 [Dmitry Khrustalev <dima@bog.msu.su>]
8515 *) Added support for building shared objects even for library-style modules
8516 (which are built from more than one object file). This now provides the
8517 ability to build mod_proxy as a shared object module. Additionally
8518 modules like mod_example are now also supported for shared object
8519 building because the generated Makefiles now no longer assume there is at
8520 least one statically linked module. [Ralf S. Engelschall]
8522 *) API: Clarify usage of content_type, handler, content_encoding,
8523 content_language and content_languages fields in request_rec. They
8524 must always be lowercased; and the strings pointed to shouldn't
8525 be modified (you must copy them to modify them). Fix a few bugs
8526 related to this. [Dean Gaudet]
8528 *) API: Clarification: except for RAW_ARGS, all command handlers can
8529 treat the char * parameters as permanent, and modifiable. There
8530 is no need to pstrdup() them. Clean up some needless pstrdup().
8533 *) Now mod_so keeps track of which module shared objects with which names
8534 are loaded and thus avoids multiple loading and unloading and irritating
8535 error_log messages. [Ralf S. Engelschall]
8537 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
8538 environment variable in the apache core. But that tweaking interferes
8539 with mod_setenv. So don't tweak if the user has specified an explicit
8540 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
8542 *) rputs() did not calculate r->sent_bodyct properly.
8543 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
8545 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
8546 name, or left unset if this value is unavailable. Apache was setting
8547 it to the IP address when unavailable.
8548 [Tony Finch <fanf@demon.net>] PR#1925
8550 *) Various improvements to the configuration and build support for compiling
8551 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
8552 OSF1 support with GCC and vendor compilers was added. This way shared
8553 object support is now provided out-of-the-box for FreeBSD, Linux,
8554 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
8555 [Ralf S. Engelschall]
8557 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
8558 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
8559 and USE_OS2_SCOREBOARD. [Dean Gaudet]
8561 *) Fix one more special locking problem for RewriteMap programs in
8562 mod_rewrite: According to the documentation of flock(), "Locks are on
8563 files, not file descriptors. That is, file descriptors duplicated
8564 through dup(2) or fork(2) do not result in multiple instances of a lock,
8565 but rather multiple references to a single lock. If a process holding a
8566 lock on a file forks and the child explicitly unlocks the file, the
8567 parent will lose its lock.". To overcome this we have to make sure the
8568 RewriteLock file is opened _AFTER_ the childs were spawned which is now
8569 the case by opening it in the child_init instead of the module_init API
8570 hook. [Ralf S. Engelschall] PR#1029
8572 *) Change to Location and LocationMatch semantics. LocationMatch no
8573 longer lets a single slash match multiple adjacent slashes in the
8574 URL. This change is for consistency with RewriteRule and
8575 AliasMatch. Multiple slashes have meaning in URLs that they do
8576 not have in (some) filesystems. Location on the other hand can
8577 be considered a shorthand for a more complicated regex, and it
8578 does match multiple slashes with a single slash -- which is
8579 also consistent with the Alias directive.

8582 *) Fix bug with mod_mime_magic causing certain files, including files
8583 of length 0, to result in no response from the server.
8586 *) The Configure script now generates src/include/ap_config.h which
8587 contains the set of defines used when Apache is compiled on a platform.
8588 This file can then be included by external modules before including
8589 any Apache header files in case they are being built separately from
8590 Apache. Along with this change, a couple of minor changes were
8591 made to make Apache's #defines coexist peacefully with any autoconf
8592 defines an external module might have. [Rasmus Lerdorf]
8594 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
8595 but without any RewriteXXXXX directives. Here mod_rewrite is given no
8596 chance by the API to initialize its per-server configuration and thus
8597 receives the wrong one from the main server. This is now avoided by
8598 remembering the server together with the config structure while
8599 configuring and later assuming there is no config when we see a
8600 difference between the remembered server and the one calling us.
8601 [Ralf S. Engelschall] PR#1790
8603 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
8604 is automatically disabled under configure time when the dbm_xxx functions
8605 are not available. Second, two heavy source code errors in the DBM
8606 support code were fixed. This makes DBM RewriteMap's usable again after
8607 a long time of brokenness. [Ralf S. Engelschall] PR#1696
8609 *) Now all configuration files support Unix-style line-continuation via
8610 the trailing backslash ("\") character. This enables us to write down
8611 complex or just very long directives in a more readable way. The

8642 supplied. This change was made to support future HTTP/1.x protocols
8643 which may require clients to send absoluteURIs for all requests.
8645 In order to achieve this change subtle changes were made to the API. In a
8646 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
8647 that the unmodified uri can be retrieved easily. r->proxyreq is not set
8648 by the core, modules must set it during the post_read_request or
8649 translate_names phase.
8651 Plus changes to the virtualhost test suite for absoluteURI testing.
8653 This fixes several bugs with the proxy proxying requests to vhosts
8654 managed by the same httpd.
8657 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
8658 code from mod_rewrite. The vhost matching is now performed by a
8659 globally available function matches_request_vhost(). [Dean Gaudet]
8661 *) Reduce memory usage, and speed up ServerAlias support. As a
8662 side-effect users can list multiple ServerAlias directives
8663 and they're all considered.

8670 *) Make \\ behave as expected. [Ronald.Tschalaer@psi.ch]
8672 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
8673 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
8675 *) API: A new source module main/util_uri.c; It contains a routine
8676 parse_uri_components() and friends which breaks a URI into its component
8677 parts. These parts are stored in a uri_components structure called
8678 parsed_uri within each request_rec, and are available to all modules.
8679 Additionally, an unparse routine is supplied which re-assembles the URI
8680 components back to an URI, optionally hiding the username:password@ part
8681 from ftp proxy requests, and other useful routines. Within the structure,
8682 you find on a ready-for-use basis:
8683 scheme; /* scheme ("http"/"ftp"/...) */
8684 hostinfo; /* combined [user[:password]@]host[:port] */
8685 user; /* user name, as in http://user:passwd@host:port/ */
8686 password; /* password, as in http://user:passwd@host:port/ */
8687 hostname; /* hostname from URI (or from Host: header) */
8688 port_str; /* port string (integer representation is in "port") */
8689 path; /* the request path (or "/" if only scheme://host was given) */
8690 query; /* Everything after a '?' in the path, if present */
8691 fragment; /* Trailing "#fragment" string, if present */
8692 This is meant to serve as the platform for *BIG* savings in
8693 code complexity for the proxy module (and maybe the vhost logic).
8696 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
8697 ${map:key}) available for all location where a string is created in
8698 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
8699 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
8700 possible expansions are consequently usable at all string creation
8701 locations. [Ralf S. Engelschall]
8703 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
8704 and not 1) and the per-virtual-server merging of directives. Now all
8705 directives except `RewriteEngine' and `RewriteOption' are either
8706 completely overridden (default) or completely inherited (when
8707 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

8710 defined but disabled (`RewriteEngine off') in per-server context.

8713 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
8714 server to bind to port 0 rather than 80. [Dean Gaudet]
8716 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
8717 (like SunOS and FreeBSD) which don't accept the locking of pipes
8718 directly. A new directive RewriteLock is introduced which can be used to
8719 setup a separate locking file which then is used for synchronization.

8725 value is stored by running "apache -i -d serverroot". [Paul Sutton]

8734 *) The mod_setenvif BrowserMatch backwards compatibility command did not
8735 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
8737 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
8738 type but with a special post-processing for the looked-up value: It
8739 parses it into alternatives according to `|' chars and then only one
8740 particular alternative is chosen randomly (this is an essential
8741 functionality needed for balancing between backend-servers when using
8742 Apache as a Reverse Proxy. The looked up value here is a list of
8743 servers). Second, `int' with the built-in maps named `tolower' and
8744 `toupper' which can be used to map URL parts to a fixed case (this is an
8745 essential feature to fix the case of server names when doing mass
8746 virtual-hosting with the help of mod_rewrite instead of using
8747 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
8748 Jay Soffian <jay@cimedia.com>] PR#1631
8750 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
8751 This directive lets Apache adjust the URL in Location-headers on HTTP
8752 redirect responses sent by the remote server. This way the virtually
8753 mapped area is no longer left on redirects and thus by-passed which is
8754 especially essential when running Apache as a reverse proxy.

8865 *) MiNT port update. [Jan Paul Schmidt]
8867 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
8868 equivalent, similarly for x-compress and compress. Apache
8869 now ignores a leading x- when comparing encodings. It also
8870 preserves the encoding the client requests (for example if
8871 it requests x-gzip, then Apache will respond with x-gzip
8872 in the Content-Encoding header).

8875 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]

8900 PR#315, 459, 485, 1433
8902 *) Yet another rearrangement of the source tree.. now all the common
8903 header files are in the src/include directory. The -Imain -Iap
8904 references in Makefiles have been changed to the simpler -Iinclude
8905 instead. In addition to simplifying the build a little bit, this
8906 also makes it clear when a module is referencing something in a
8907 other than kosher manner (e.g., the proxy including mod_mime.h).
8908 Module-private header files (the proxy, mod_mime, the regex library,
8909 and mod_rewrite) have not been moved to src/include; nor have
8910 the OS-abstraction files. [Ken Coar]
8912 *) Fix a bug where r->hostname didn't have the :port stripped
8913 from it. [Dean Gaudet]
8915 *) Tweaked the headers_out table size, and the subprocess_env

8917 MAKE_TABLE_PROFILE which can help discover make_table()
8918 calls that use too small an initial guess, see alloc.c.
8921 *) Options and AllowOverride weren't properly merging in the main
8922 server setting inside vhosts (only an issue when you have no
8923 <Directory> or other section containing an Options that affects
8924 a request). Options +foo or -foo in the main_server wouldn't
8925 affect the main_server's lookup defaults. [Dean Gaudet]
8927 *) Variable 'cwd' was being used pointlessly before being set.
8930 *) r->allowed handling cleaned up in the standard modules.

8936 *) SIGURG doesn't exist everywhere.
8937 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8939 *) mod_unique_id was erroneously generating a second unique id when
8940 an internal redirect occured. Such redirects occur, for example,
8941 when processing a DirectoryIndex match. [Dean Gaudet]
8943 *) API: table_add, table_merge, and table_set include implicit pstrdup()
8944 of the key and value. But in many cases this is not required
8945 because the key/value is a constant, or the value has been built
8946 by pstrcat() or other similar means. New routines table_addn,
8947 table_mergen, and table_setn have been added to the API, these
8948 routines do not pstrdup() their arguments. The core code and
8949 standard modules were changed to take advantage of these routines.
8950 The resulting server is up to 20% faster in some situations.
8952 Note that it is easy to get code subtly wrong if you pass a key/value
8953 which is in a pool other than the pool of the table. The only
8954 safe thing to do is to pass key/values which are in the pool of
8955 the table, or in one of the ancestors of the pool of the table.
8956 i.e. if the table is part of a subrequest, a value from the main
8957 request's pool is OK since the subrequest pool is a sub_pool of the
8958 main request's pool (and therefore has a lifespan at most as long as
8959 the main pool). There is debugging code which can detect improper
8960 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
8961 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
8963 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
8964 which don't exist on disk more gracefully; handles vhosts properly.
8965 Update documentation to reflect the code -- if there's no
8966 MimeMagicFile directive then the module is not enabled.
8969 *) PORT: Some older *nix dialects cannot automatically start scripts
8970 which begin with a #! interpreter line (the shell starts the scripts
8971 appropriately on these platforms). Apache now supports starting of
8972 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
8973 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
8976 *) API: "typedef array_header table" removed from alloc.h, folks should
8977 have been writing to use table as if it were an opaque type, but even
8978 some standard modules got this wrong. By changing the definition
8979 to "typedef struct table table" module authors will receive compile
8980 time warnings that they're doing the wrong thing. This change
8981 facilitates future changes with more sophisticated table
8982 structures. Specifically, module authors should be using table_elts()
8983 to get access to an array_header * for the table. [Dean Gaudet]
8985 *) API: Renamed new_connection() to avoid namespace collision with LDAP
8986 library routines. [Ken Coar, Rasmus Lerdorf]
8988 *) WIN32: mod_speling is now available on the Win32 platform.
8991 *) For clarity the following compile time definition was changed:
8993 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
8995 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
8996 and not be a general notice that the OS has mmap(). Now the
8997 HAVE_MMAP/SHMGET #defines strictly are informational that the
8998 OS has that method of shared memory; the type to use for
8999 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
9000 and USE_SHMGET_SCOREBOARD). This allows outside modules to
9001 determine if shared memory is available and allows Apache
9002 to determine the best method to use for the scoreboard.

9006 as do various earlier versions. It should be safe on all versions.

9153 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
9155 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
9157 *) A few cleanups in mod_info to make it thread-safe, and remove an
9158 off-by-5 bug that could hammer \0 on the stack. [Dean Gaudet]
9160 *) no2slash() was O(n^2) in the length of the input. Make it O(n).

9182 alloc.c (affects win32 only). [Ben Hyde]
9184 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
9186 *) send_fd_length() did not calculate total_bytes_sent properly.
9187 [Ben Reser <breser@regnow.com>] PR#1366
9189 *) The bputc() macro was not properly integrated with the chunking
9190 code; in many cases modules using bputc() could cause completely
9191 bogus chunked output. (Typically this will show up as problems
9192 with Internet Explorer 4.0 reading a page, but other browsers
9193 having no problem.) [Dean Gaudet]
9195 *) Create LARGE_WRITE_THRESHOLD define which determines how many
9196 bytes have to be supplied to bwrite() before it will consider
9197 doing a writev() to assemble multiple buffers in one system
9198 call. This is critical for modules such as mod_include,
9199 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
9200 strings in some cases. The result would be extra effort
9201 setting up writev(), and in many cases extra effort building
9202 chunks. The default is 31, it can be overriden at compile
9205 *) Move the gid switching code into the child so that log files
9206 and pid files are opened with the root gid.

9213 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
9214 so the functionality is available to applications other than the
9215 server itself (like the src/support tools). [Ken Coar]
9217 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
9218 the libap consolidation work. [Ken Coar]

9312 This turns out to be a bug in Winsock - select() doesn't always
9313 return the correct status. [Ben Laurie]
9315 *) Directives owned by http_core can now use the new check_cmd_context()
9316 routine to ensure that they're not being used within a container
9317 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
9319 *) PORT: Recent changes made it necessary to add explicit prototype
9320 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
9322 *) It was necessary to distinguish between resources which are
9323 allocated in the parent, for cleanup in the parent, and resources
9324 which are allocated in each child, for cleanup in each child.
9325 A new pool was created which is passed to the module child_init
9326 and child_exit functions; modules are free to register per-child
9327 cleanups there. This fixes a bug with reliable piped logs.
9330 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
9331 unless it was also doing FancyIndexes, but it displayed the
9332 HeaderName file at the top under all circumstances. It now shows
9333 the ReadmeName file for simple indices, too, as it should.
9336 *) http_core was mmap()ing even in cases where it wasn't going to
9337 read the file. [Ben Hyde <bhyde@gensym.com>]
9339 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
9340 Now the rewriting engine (the heart of mod_rewrite) is organized more
9341 straight-forward, first time well documented and reduced to the really
9342 essential parts. All redundant cases were stripped off and processing now
9343 is the same for both per-server and per-directory context with only a
9344 minimum difference (the prefix stripping in per-dir context). As a
9345 side-effect some subtle restrictions and two recently discovered problems
9346 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
9347 context and restrictions on the substitution URL on redirects.
9348 Additionally some minor source cleanups were done.

9503 Changes with Apache 1.3b2 (there is no 1.3b1)
9505 *) TestCompile was not passing $LIBS [Dean Gaudet]
9507 *) Makefile.tmpl was not using $CFLAGS in the link phase.
9510 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
9511 rudimentary memory debugger which can be used on live servers with
9512 low impact -- it sets all allocated and freed memory bytes to 0xa5.
9513 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
9514 and free() for each object. This is far more expensive and should
9515 only be used for testing with tools such as Electric Fence and
9516 Purify. See main/alloc.c for more details. [Dean Gaudet]
9518 *) Configure uses a sh trap and didn't set its exitcode properly.
9519 [Dean Gaudet] PR#1159
9521 *) Yet another vhost revamp. Add the NameVirtualHost directive which
9522 explicitly lists the ip:port pairs that are to be used for name-vhosts.
9523 From a given ip:port, regardless what the Host: header is, you can
9524 only reach the vhosts defined on that ip:port. The precedence of
9525 vhosts was reversed to match other precedences in the config --
9526 the earlier vhosts override the later vhosts. All vhost matching was
9527 moved into http_vhost.[ch]. [Dean Gaudet]
9529 *) ap_inline can be used to force inlining. GNUC __attribute__() can
9530 be used for whatever reason is appropriate (i.e. format() warnings
9531 for printf style functions). Both are enabled only with
9532 gcc >= 2.7.x (so that we have fewer support issues with older
9533 versions). [Dean Gaudet]
9535 *) Fix support for Proxy Authentication (we were testing the response
9536 status too early). [Marc Slemko]
9538 *) CoreDumpDirectory directive directs where the core file is
9539 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are

9543 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
9545 *) When booting, apache will now detach itself from stdin, stdout,
9546 and stderr. stderr will not be detached until after the config
9547 files have been read so you will be able to see initial error
9548 messages. After that all errors are logged in the error_log.
9549 This makes it more convenient to start apache via rsh, ssh,
9550 or crontabs. [Dean Gaudet] PR#523
9552 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
9553 Also removed the auto-generated link to www.apache.org that was the

9556 *) send_fb would not detect aborted connections in some situations.

9564 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
9566 *) mod_autoindex improperly counted &escapes; as more than one
9567 character in the description. It also improperly truncated
9568 descriptions that were exactly the maximum length.
9571 *) RedirectMatch was not properly escaping the result (PR#1155). Also
9572 "RedirectMatch /advertiser/(.*) $1" is now permitted.
9575 *) mod_include now uses symbolic names to check for request success
9576 and return HTTP errors, and correctly handles all types of
9577 redirections (previously it only did temporary redirect correctly).
9578 [Ken Coar, Roy Fielding]
9580 *) mod_userdir was modifying r->finfo in cases where it wasn't setting

9594 *) Fixed error in proxy_util.c when looping through multiple host IP
9595 addresses. [Lars Eilebrecht] PR#974
9597 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
9598 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
9599 bytes before writing, but it will never split a log entry across a
9600 buffer boundary. [Dean Gaudet]
9602 *) API: the short_score record has been split into two pieces, one which
9603 the parent writes on, and one which the child writes on. As part of
9604 this change the get_scoreboard_info() function was removed, and
9605 scoreboard_image was exported. This change fixes a race condition
9606 in file based scoreboard systems, and speeds up changes involving the
9607 scoreboard in earlier 1.3 development. [Dean Gaudet]
9609 *) API: New register_other_child() API (see http_main.h) which allows
9610 modules to register children with the parent for maintenance. It
9611 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
9613 *) API: New piped_log API (see http_log.h) which implements piped logs,
9614 and will use register_other_child to implement reliable piped logs
9615 when it is available. The reliable piped logs part can be disabled
9616 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
9617 logs is only available on Unix. [Dean Gaudet]
9619 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
9620 meets_conditions(). This allows conditional HTTP selection to be
9621 handled separately from the storing of the header fields, and provides
9622 the ability for CGIs to set their own ETags for conditional checking.

9630 *) New module, "mod_speling", which can help find files even when
9631 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
9633 *) API: New function child_terminate() triggers the child process to
9634 exit, while allowing the child finish what it needs to for the
9635 current request first.

9638 *) Windows now defaults to using full status reports with mod_status.

9641 *) *Really* disable all mod_rewrite operations if the engine is off.
9642 Some things (like RewriteMaps) were checked/performed even if they
9643 weren't supposed to be. [Ken Coar] PR #991
9645 *) Implement a new timer scheme which eliminates the need to call alarm() all
9646 the time. Instead a counter in the scoreboard for each child is used to
9647 show when the child has made forward progress. The parent samples this
9648 counter every scoreboard maintenance cycle, and issues SIGALRM if no
9649 progress has been made in the timeout period. This reduces the static
9650 request best-case syscall count to 22 from 29. This scheme is only
9651 used by systems with memory-based scoreboards. [Dean Gaudet]
9653 *) The proxy now properly handles CONNECT requests which are sent
9654 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
9656 *) A script called apachectl has been added to the support
9657 directory. This script allows you to do things such as
9658 "apachectl start" and "apachectl restart" from the command
9661 *) Modules and core routines are now put into libraries, which
9662 simplifies the link line tremendously (among other advantages).
9665 *) Some of the MD5 names defined in Apache have been renamed to have
9666 an `ap_' prefix to avoid conflicts with routines supplied by
9667 external libraries. [Ken Coar]
9669 *) Removal of mod_auth_msql.c from the distribution. There are many
9670 other options for databases today. Rather than offer one option,
9671 offer none at this time. mod_auth_msql and other SQL database
9672 authentication modules can be found at the Apache Module Registry.
9673 http://modules.apache.org/ It would be nice to offer a generic
9674 mod_auth_sql option in the near future.
9676 *) PORT: BeOS support added [Alexei Kosut]
9678 *) Configure no longer accepts the -make option, since it creates
9679 Makefile on the fly based on Makefile.tmpl and Configuration.
9681 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
9682 of forcibly killing off all its processes and exiting without
9683 cleaning up. [Alexei Kosut]
9685 *) API: A new field in the request_rec, r->mtime, has been added to
9686 avoid gratuitous parsing of date strings. It is intended to hold
9687 the last-modified date of the resource (if applicable). An
9688 update_mtime() routine has also been added to advance it if
9689 appropriate. [Roy Fielding, Ken Coar]
9691 *) SECURITY: If a htaccess file can not be read due to bad permissions,
9692 deny access to the directory with a HTTP_FORBIDDEN. The previous
9693 behavior was to ignore the htaccess file if it could not be read.
9694 This change may make some setups with unreadable htaccess files
9695 stop working. [Marc Slemko] PR#817
9697 *) Add aplog_error() providing a mechanism to define levels of
9698 verbosity to the server error logging. This addition also provides
9699 the ability to log errors using syslogd. Error logging is configurable
9700 on a per-server basis using the LogLevel directive. Conversion
9701 of log_*() in progress. [Randy Terbush]
9703 *) Further enhance aplog_error() to not log filename, line number, and
9704 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
9706 *) WIN32: Canonicalise filenames under Win32. Short filenames are
9707 converted to long ones. Backslashes are converted to forward
9708 slashes. Case is converted to lower. Parts of URLs that do not
9709 correspond to files are left completely alone. [Ben Laurie]
9711 *) PORT: 2 new OSs added to the list of ports:
9712 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
9713 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
9715 *) Add the server version (SERVER_VERSION macro) to the "server
9716 configured and running" entry in the error_log. Also build an
9717 object file at link-time that contains the current time
9718 (SERVER_BUILT global const char[]), and include that in the
9721 *) Set r->headers_out when sending responses from the proxy.
9722 This fixes things such as the logging of headers sent from
9723 the proxy. [Marc Slemko] PR#659
9725 *) support/httpd_monitor is no longer distributed because the
9726 scoreboard should not be file based if at all possible. Use
9727 mod_status to see current server snapshot.
9729 *) (set_file_slot): New function, allowing auth directives to be
9730 independent of the server root, so the server documents can be
9731 moved to a different directory or machine more easily.
9732 [David J. MacKenzie]
9734 *) If no TransferLog is given explicitly, decline
9735 to log. This supports coexistence with other logging modules,
9736 such as the custom one that UUNET uses. [David J. MacKenzie]
9738 *) Check for titles in server-parsed HTML files.
9739 Ignore leading newlines and returns in titles. The old behavior
9740 of replacing a newline after <title> with a space causes the
9741 title to be misaligned in the listing. [David J. MacKenzie]
9743 *) Change mod_cern_meta to be configurable on a per-directory basis.
9744 [David J. MacKenzie]
9746 *) Add 'Include' directive to allow inclusion of configuration
9747 files within configuration files. [Randy Terbush]
9749 *) Proxy errors on connect() are logged to the error_log (nothing
9750 new); now they include the IP address and port that failed
9751 (*that's* new). [Ken Coar, Marc Slemko] PR#352
9753 *) Various architectures now define USE_MMAP_FILES which causes
9754 the server to use mmap() for static files. There are two
9755 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
9756 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
9757 number of bytes written in one cycle from a single mmap()d object,
9758 default 32768). [Dean Gaudet]
9760 *) API: Added post_read_request API phase which is run right after reading
9761 the request from a client, or right after an internal redirect. It is
9762 useful for modules setting environment variables that depend only on
9763 the headers/contents of the request. It does not run during subrequests
9764 because subrequests inherit pretty much everything from the main
9765 request. [Dean Gaudet]
9767 *) Added mod_unique_id which is used to generate a unique identifier for
9768 each hit, available in the environment variable UNIQUE_ID.
9771 *) init_modules is now called after the error logs have been opened. This
9772 allows modules to emit information messages into the error logs.
9775 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
9776 information for case where proxy module is not available. [Marc Slemko]
9778 *) PORT: Apache has need for mutexes to serialize its children around
9779 accept. In prior versions either fcntl file locking or flock file
9780 locking were used. The method is chosen by the definition of
9781 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
9782 and FLOCK for flock(). New options have been added:
9783 - SYSVSEM to use System V style semaphores
9784 - PTHREAD to use POSIX threads (appears to work on Solaris only)
9785 - USLOCK to use IRIX uslock
9786 Based on timing various techniques, the following changes were made
9788 - Linux 2.x uses flock instead of fcntl
9789 - Solaris 2.x uses pthreads
9790 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
9791 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
9792 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
9793 Martijn Koster <m.koster@pobox.com>]
9795 *) PORT: The semantics of accept/select make it very desirable to use
9796 mutexes to serialize accept when multiple Listens are in use. But
9797 in the case where only a single socket is open it is sometimes
9798 redundant to serialize accept(). Not all unixes do a good job with
9799 potentially dozens of children blocked on accept() on the same
9800 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
9801 the server will avoid serialization when listening on only one socket,
9802 and use serialization when listening on multiple sockets.
9803 [Dean Gaudet] PR#467
9805 *) Configure changes: TestLib replaced by TestCompile, which has
9806 some additional capability (such as doing a sanity check of
9807 the compiler and flags selected); the version of Solaris is now
9808 available via the #define value of SOLARIS2; IRIX n32bit libs
9809 now supported and selectable by new Configuration Rule: IRIXN32;
9810 We no longer default to -O2 optimization. [Jim Jagielski]
9812 *) Updated Configure: Configuration now uses AddModule to specify
9813 module source or binary file location, relative to src directory.
9814 Modules can be dropped into modules/extra, or in their own
9815 directory, and modules can come with a Makefile or Configure can
9816 create one. Modules can add compiler or library information to
9817 generated Makefiles. [Paul Sutton]
9819 *) Source core re-organisation: distributed modules are now in
9820 modules/standard. All other source code is in main. OS-specific
9821 code is in os/{unix,emx,win32} directories. [Paul Sutton]
9823 *) mod_browser has been removed, since it's replaced by mod_setenvif.
9826 *) Fix another long-standing bug in sub_req_lookup_file where it would
9827 happily skip past access checks on subdirectories looked up with
9828 relative paths. (It's used by mod_dir, mod_negotiation,
9829 and mod_include.) [Dean Gaudet]
9831 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
9832 N is the number of <Directory> sections, and M is the number of
9833 components in the filename of an object.
9835 To achieve this optimization the following config changes were made:
9836 - Wildcards (* and ?, not the regex forms) in <Directory>s,
9837 <Files>s, and <Location>s now treat a slash as a special
9838 character. For example "/home/*/public_html" previously would
9839 match "/home/a/andrew/public_html", now it only matches things
9840 like "/home/bob/public_html". This mimics /bin/sh behaviour.
9841 - It's possible now to use [] wildcarding in <Directory>, <Files>
9843 - Regex <Directory>s are applied after all non-regex <Directory>s.
9847 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
9848 and corrupted paths. [Dean Gaudet]
9850 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
9851 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
9852 be accessed now via backreferences $1..$9 in RewriteConds test-against
9853 strings in addition to RewriteRules subst string. Second the grouped
9854 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
9855 via backreferences %1..%9 both in following RewriteCond test-against
9856 strings and RewriteRules subst string. This provides maximum flexibility
9857 through the use of backreferences.
9858 Additionally the rewriting engine was cleaned up by putting common
9859 code to the new expand_backrefs_inbuffer() function.
9860 [Ralf S. Engelschall]
9862 *) When merging the main server's <Directory> and <Location> sections into
9863 a vhost, put the main server's first and the vhost's second. Otherwise
9864 the vhost can't override the main server. [Dean Gaudet] PR#717
9866 *) The <Directory> code would merge and re-merge the same section after
9867 a match was found, possibly causing problems with some modules.
9870 *) ip-based vhosts are stored and queried using a hashing function, which
9871 has been shown to improve performance on servers with many ip-vhosts.
9872 Some other changes had to be made to accommodate this:
9873 - the * address for vhosts now behaves like _default_
9874 - the matching process now is:
9875 - match an ip-vhost directly via hash (possibly matches main
9877 - if that fails, just pretend it matched the main server
9878 - if so far only the main server has been matched, perform
9879 name-based lookups (ServerName, ServerAlias, ServerPath)
9880 *only on name-based vhosts*
9881 - if they fail, look for _default_ vhosts
9882 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
9884 *) dbmmanage overhaul:
9885 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
9886 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
9887 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
9888 - provide better seed for rand
9889 - prompt for password as per getpass(3) (turn off echo, read from
9891 - use "newstyle" crypt based on $Config{osname} ($^O)
9892 - will not add a user if already in database, use new `update' command
9894 - added `check' command to check a users' password
9895 - added `import' command to convert existing password text-files or
9896 dbm files exported with `view'
9897 - more descriptive usage, general cleanup, 'use strict' clean, etc.
9900 *) Added psocket() which is a pool form of socket(), various places within
9901 the proxy weren't properly blocking alarms while registering the cleanup
9902 for its sockets. bclose() now uses pclose() and pclosesocket(). There
9903 was a bug where the client socket was being close()d twice due a still
9904 registered cleanup. [Dean Gaudet]
9906 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
9909 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
9910 [Jason Venner <jason@idiom.com>] PR#667
9912 *) Enable ``=""'' for RewriteCond directives to match against
9913 the empty string. This is the preferred way instead of ``^$''.
9914 [Ralf S. Engelschall]
9916 *) Fixed an infinite loop in mod_imap for references above the server root
9917 [Dean Gaudet] PR#748
9919 *) mod_proxy now has a ReceiveBufferSize directive, similar to
9920 SendBufferSize, so that the TCP window can be set appropriately
9921 for LFNs. [Phillip A. Prindeville]
9923 *) mod_browser has been replaced by the more general mod_setenvif
9924 (courtesy of Paul Sutton). BrowserMatch* directives are still
9925 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
9926 UnSetEnvIfZero directives. [Ken Coar]
9928 *) "HostnameLookups double" forces double-reverse DNS to succeed in
9929 order for remote_host to be set (for logging, or for the env var
9930 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
9933 *) mod_access overhaul:
9934 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
9935 and cidr syntax (i.e. 10.1.0.0/16). PR#762
9936 - Critical path was sped up by pre-computing a few things at config time.
9937 - The undocumented syntax "allow user-agents" was removed,
9938 the replacement is "allow from env=foobar" combined with mod_browser.
9939 - When used with hostnames it now forces a double-reverse lookup
9940 no matter what the directory settings are. This double-reverse
9941 doesn't affect any of the other routines that use the remote
9942 hostname. In particular it's still passed to CGIs and the log
9943 without the double-reverse check. Related PR#860.
9946 *) When a large bwrite() occurs (larger than the internal buffer size),
9947 while there is already something in the buffer, apache will combine
9948 the large write and the buffer into a single writev(). (This is
9949 in anticipation of using mmap() for reading files.)
9952 *) In obscure cases where a partial socket write occurred while chunking,
9953 Apache would omit the chunk header/footer on the next block. Cleaned
9954 up other bugs/inconsistencies in error conditions in buff.c. Fixed
9955 a bug where a long pause in DNS lookups could cause the last packet
9956 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
9958 *) API: Added child_exit function to module structure. This is called
9959 once per "heavy-weight process" just before a server child exit()'s
9960 e.g. when max_requests_per_child is reached, etc.
9961 [Doug MacEachern, Dean Gaudet]
9963 *) mod_include cleanup showed that handle_else was being used to handle
9964 endif. It didn't cause problems, but it was cleaned up too.
9967 *) mod_cern_meta would attempt to find meta files for the directory itself
9968 in some cases, but not in others. It now avoids it in all cases.
9971 *) mod_mime_magic would core dump if there was a decompression error.
9972 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
9974 *) PORT: some variants of DGUX require -lsocket -lnsl
9975 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
9977 *) mod_autoindex now allows sorting of FancyIndexed directory listings
9978 by the various fields (name, size, et cetera), either in ascending
9979 or descending order. Just click on the column header. [Ken Coar]
9981 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
9982 CPUs like the Alpha. Apache still stores ints in pointers, but that's
9983 the relatively safe direction. [Dean Gaudet] PR#344
9985 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
9986 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
9988 *) child_main avoids an unneeded call to select() when there is only one
9989 listening socket. [Dean Gaudet]
9991 *) In the event that the server is starved for idle servers it will
9992 spawn 1, then 2, then 4, ..., then 32 servers each second,
9993 doubling each second. It'll also give a warning in the errorlog
9994 since the most common reason for this is a poor StartServers
9995 setting. The define MAX_SPAWN_RATE can be used to raise/lower
9996 the maximum. [Dean Gaudet]
9998 *) Apache now provides an effectively unbuffered connection for
9999 CGI scripts. This means that data will be sent to the client
10000 as soon as the CGI pauses or stops output; previously, Apache would
10001 buffer the output up to a fixed buffer size before sending, which
10002 could result in the user viewing an empty page until the CGI finished
10003 or output a complete buffer. It is no longer necessary to use an
10004 "nph-" CGI to get unbuffered output. Given that most CGIs are written
10005 in a language that by default does buffering (e.g. perl) this
10006 shouldn't have a detrimental effect on performance.
10008 "nph-" CGIs, which formerly provided a direct socket to the client
10009 without any server post-processing, were not fully compatible with
10010 HTTP/1.1 or SSL support. As such they would have had to implement
10011 the transport details, such as encryption or chunking, in order
10012 to work properly in certain situations. Now, the only difference
10013 between nph and non-nph scripts is "non-parsed headers".
10014 [Dean Gaudet, Sameer Parekh, Roy Fielding]
10016 *) If a BUFF is switched from buffered to unbuffered reading the first
10017 bread() will return whatever remained in the buffer prior to the
10018 switch. [Dean Gaudet]
10020 Changes with Apache 1.3a1
10022 *) Added another Configure helper script: TestLib. It determines
10023 if a specified library exists. [Jim Jagielski]
10025 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
10026 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
10029 *) PORT: Some architectures use size_t for various lengths in network
10030 functions such as accept(), and getsockname(). The definition
10031 NET_SIZE_T is used to control this. [Dean Gaudet]
10033 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
10034 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
10035 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
10037 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
10038 [Igor N Kovalenko <infoh@mail.wplus.net>]
10040 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
10041 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
10042 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
10043 [Dean Gaudet] related PR#875
10045 *) API: Correct child_init() slot declaration from int to void, to
10046 match the init() declaration. Update mod_example to use the new
10049 *) added transport handle slot (t_handle) to the BUFF structure
10052 *) get_client_block() returns wrong length if policy is
10053 REQUEST_CHUNKED_DECHUNK.
10054 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
10056 *) Support the image map format of FrontPage. For example:

10058 ["Chris O'Byrne" <obyrne@iol.ie>] PR#807
10060 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
10061 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
10063 *) AddModuleInfo directive for mod_info which allows you to annotate
10064 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
10066 *) Added NoProxy directive to avoid using ProxyRemote for selected
10067 addresses. Added ProxyDomain directive to cause unqualified
10068 names to be qualified by redirection.
10069 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
10071 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
10072 header to the remote host in the proxy. [Sameer Parekh and
10075 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
10076 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
10077 URLs, fixed rewritelog(), fixed forced response code handling on
10078 redirects from within .htaccess files, disabled pipe locking under
10079 braindead SunOS 4.1.x, allow env variables to be set even on rules with
10080 no substitution, bugfixed situations where HostnameLookups is off, made
10081 mod_rewrite more thread-safe for NT port and fixed problem when creating
10082 an empty query string via "xxx?".
10083 This update also removes the copyright of Ralf S. Engelschall,
10084 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
10085 exclusively copyrighted by the Apache Group now. This happened because
10086 the author now has gifted mod_rewrite exclusively to the Apache Group and
10087 no longer maintains an external version.
10088 [Ralf S. Engelschall]
10090 *) API: Added child_init function to module structure. This is called
10091 once per "heavy-weight process" before any requests are handled.
10092 See http_config.h for more details. [Dean Gaudet]
10094 *) Anonymous_LogEmail was logging on each subrequest.
10095 [Dean Gaudet] PR#421, 868
10097 *) API: Added is_initial_req() which tests if the request being
10098 processed is the initial request, or a subrequest.
10101 *) Extended SSI (mod_include) now handles additional relops for
10102 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
10104 *) Configure fixed to correctly propagate user-selected options and
10105 settings (such as CC and OPTIM) to Makefiles other than
10106 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
10108 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
10109 directory indices to start with the contents of the HeaderName file
10110 if there is one. If there isn't one, the behaviour is unchanged.
10111 [Ken Coar, Roy Fielding, Andrey A. Chernov]
10113 *) WIN32: Modules can now be dynamically loaded DLLs using the
10114 LoadModule/LoadFile directives. Note that module DLLs must be
10115 compiled with the multithreaded DLL version of the runtime library.
10116 [Alexei Kosut and Ben Laurie]
10118 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
10119 This allows the admin to completely remove automatic indexing
10120 from the server, while still supporting the basic functions of
10121 trailing-slash redirects and DirectoryIndex files. Note that if
10122 you're carrying over an old Configuration file and you use directory
10123 indexing then you'll want to add:
10125 Module autoindex_module mod_autoindex.o
10127 before mod_dir in your Configuration. [Dean Gaudet]
10129 *) popendir/pclosedir created to properly protect directory scanning.
10130 [Dean Gaudet] PR#525
10132 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
10133 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
10134 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
10137 *) The AccessFileName directive can now take more than one filename.
10138 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
10140 *) The new mod_mime_magic can be used to "magically" determine the type
10141 of a file if the extension is unknown. Based on the unix file(1)
10142 command. [Ian Kluft <ikluft@cisco.com>]
10144 *) We now determine and display the time spent processing a
10145 request if desired. [Jim Jagielski]
10147 *) mod_status: PID field of "dead" child slots no longer displays
10148 main httpd process's PID. [Jim Jagielski]
10150 *) Makefile.nt added - to build all the bits from the command line:
10151 nmake -f Makefile.nt
10152 Doesn't yet work properly. [Ben Laurie]
10154 *) Default text of 404 error is now "Not Found" rather than the
10155 potentially misleading "File Not Found". [Ken Coar]
10157 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
10158 for the net if we require people that actually need this data to
10159 enable it. [Linus Torvalds]
10161 *) directory_walk() is an expensive function, keep a little more state to
10162 avoid needless string counting. Add two new functions make_dirstr_parent
10163 and make_dirstr_prefix which replace all existing uses of make_dirstr.
10164 The new functions are a little less general than make_dirstr, but
10165 work more efficiently (less memory, less string counting).
10168 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
10169 to LDFLAGS) to avoid complications with lex rules in make files.
10170 [Dean Gaudet] PR#372
10172 *) run_method optimized to avoid needless scanning over NULLs in the
10173 module list. [Dean Gaudet]
10175 *) Revamp of (unix) scoreboard management code such that it avoids
10176 unnecessary traversals of the scoreboard on each hit. This is
10177 particularly important for high volume sites with a large
10178 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
10179 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
10180 httpd.h. [Dean Gaudet]
10182 *) In configurations using multiple Listen statements it was possible for
10183 busy sockets to starve other sockets of service. [Dean Gaudet]
10185 *) Added hook so standalone_main can be replaced at compile time
10186 (define STANDALONE_MAIN)
10189 *) Lowest-level read/write functions in buff.c will be replaced with
10190 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
10191 compile time. The default sfio discipline will behave as apache
10192 would without sfio compiled in.
10195 *) Enhance UserDir directive (mod_userdir) to accept a list of
10196 usernames for the 'disable' keyword, and add 'enable user...' to
10197 selectively *en*able userdirs if they're globally disabled.
10200 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
10201 will work with Netscape dbm files. (dbmmanage will probably not
10202 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
10204 *) Add a ListenBacklog directive to control the backlog parameter
10205 passed to listen(). Also change the default to 511 from 512.
10208 *) API: A new handler response DONE which informs apache that the
10209 request has been handled and it can finish off quickly, similar to
10210 how it handles errors. [Rob Hartill]
10212 *) Turn off chunked encoding after sending terminating chunk/footer
10213 so that we can't do it twice by accident. [Roy Fielding]
10215 *) mod_expire also issues Cache-Control: max-age headers.
10218 *) API: Added kill_only_once option for free_proc_chain so that it won't
10219 aggressively try to kill off specific children. For fastcgi.

10222 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
10224 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
10225 When used together, these cause mod_dir to emit HEIGHT and WIDTH
10226 attributes in the FancyIndexing IMG tags. [Ken Coar]
10228 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
10230 *) PORT: Added Windows NT support
10231 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
10233 Changes with Apache 1.2.6
10235 *) mod_include when using XBitHack Full would send ETags in addition to
10236 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
10237 [Dean Gaudet] PR#1133
10239 *) SECURITY: When a client connects to a particular port/addr, and
10240 gives a Host: header ensure that the virtual host requested can
10241 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
10243 *) Support virtual hosts with wildcard port and/or multiple ports
10244 properly. [Ed Korthof <ed@organic.com>]
10246 *) Fixed some case-sensitivity issues according to RFC2068.
10249 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
10250 and mod_include.c. [Dean Gaudet]
10252 *) Variable 'cwd' was being used pointlessly before being set.
10255 *) SIGURG doesn't exist on all platforms.
10256 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
10258 *) When an error occurs during a POST, or other operation with a
10259 request body, the body has to be read from the net before allowing
10260 a keepalive session to continue. [Roy Fielding] PR#1399
10262 *) When an error occurs in fcntl() locking suggest the user look up
10263 the docs for LockFile. [Dean Gaudet]
10265 *) table_set() and table_unset() did not deal correctly with
10266 multiple occurrences of the same key. [Stephen Scheck
10267 <sscheck@infonex.net>, Ben Laurie] PR#1604
10269 *) send_fd_length() did not calculate total_bytes_sent properly in error
10270 cases. [Ben Reser <breser@regnow.com>] PR#1366
10272 *) r->connection->user was allocated in the wrong pool causing corruption
10273 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
10275 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10276 Also removed the auto-generated link to www.apache.org that was the
10277 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10279 *) Multiple "close" tokens may have been set in the "Connection"
10280 header, not an error, but a waste.
10281 [Ronald.Tschalaer@psi.ch] PR#1683
10283 *) "basic" and "digest" auth tokens should be tested case-insensitive.
10284 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
10286 *) It appears the "257th byte" bug (see
10287 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
10288 at the 256th byte as well. Fixed. [Dean Gaudet]
10290 *) mod_rewrite would not handle %3f properly in some situations.
10293 *) Apache could generate improperly chunked HTTP/1.1 responses when
10294 the bputc() or rputc() functions were used by modules (such as
10295 mod_include). [Dean Gaudet]
10297 *) #ifdef wrap a few #defines in httpd.h to make life easier on
10298 some ports. [Ralf Engelschall]
10300 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
10302 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
10304 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
10306 Changes with Apache 1.2.5
10308 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
10309 only an issue on systems without a MAXDNAME define or where
10310 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
10312 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
10315 *) Fix core dump in the ftp proxy when reading incorrectly formatted
10316 directory listings. [Marc Slemko]
10318 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
10321 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
10322 is used to read various types of files such as htaccess and
10323 htpasswd files. [Marc Slemko]
10325 *) SECURITY: Ensure that the buffer returned by ht_time is always
10326 properly null terminated. [Marc Slemko]
10328 *) SECURITY: General mod_include cleanup, including fixing several
10329 possible buffer overflows and a possible infinite loop. This cleanup
10330 was done against 1.3 code and then backported to 1.2, the result
10331 is a large difference (due to indentation cleanup in 1.3 code).
10332 Users interested in seeing a smaller set of relevant differences
10333 should consider comparing against src/modules/standard/mod_include.c
10334 from the 1.3b3 release. Non-indentation changes to mod_include
10335 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
10337 *) SECURITY: Numerous changes to mod_imap in a general cleanup
10338 including fixing a possible buffer overflow. This cleanup also
10339 was done with 1.3 code as a basis, see the the previous note
10340 about mod_include. [Dean Gaudet]
10342 *) SECURITY: If a htaccess file can not be read due to bad
10343 permissions, deny access to the directory with a HTTP_FORBIDDEN.
10344 The previous behavior was to ignore the htaccess file if it could not
10345 be read. This change may make some setups with unreadable
10346 htaccess files stop working. PR#817 [Marc Slemko]
10348 *) SECURITY: no2slash() was O(n^2) in the length of the input.
10349 Make it O(n). This inefficiency could be used to mount a denial
10350 of service attack against the Apache server. Thanks to
10351 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
10352 this. [Dean Gaudet]
10354 *) mod_include used uninitialized data for some uses of && and ||.
10355 [Brian Slesinsky <bslesins@wired.com>] PR#1139
10357 *) mod_imap should decline all non-GET methods.
10358 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
10360 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10362 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10363 r->filename. Since those two are meant to be in sync with each other
10364 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
10366 *) mod_include did not properly handle all possible redirects from sub-
10367 requests. [Ken Coar]
10369 *) Inetd mode (which is buggy) uses timeouts without having setup the
10370 jmpbuffer. [Dean Gaudet] PR#1064
10372 *) Work around problem under Linux where a child will start looping
10373 reporting a select error over and over.
10374 [Rick Franchuk <rickf@transpect.net>] PR#1107
10376 Changes with Apache 1.2.4
10378 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
10379 always making requests with the full-URI instead of just the URI path.
10380 [Marc Slemko, Roy Fielding]
10382 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
10383 on this platform. [Marc Slemko]
10385 Changes with Apache 1.2.3
10387 *) The request to a remote proxy was mangled if it was generated as the
10388 result of a ProxyPass directive. URL schemes other than http:// were not
10389 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
10390 PR#812 [Lars Eilebrecht]
10392 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10393 information for case where proxy module is not available. [Marc Slemko]
10395 *) Force proxy to always respond as HTTP/1.0, which it was failing to
10396 do for errors and cached responses. [Roy Fielding]
10398 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
10400 Changes with Apache 1.2.2 [not released]
10402 *) Fixed another long-standing bug in sub_req_lookup_file where it would
10403 happily skip past access checks on subdirectories looked up with relative
10404 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
10407 *) Add lockfile name to error message printed out when
10408 USE_FLOCK_SERIALIZED_ACCEPT is defined.
10411 *) Enhanced the chunking and error handling inside the buffer functions.
10412 [Dean Gaudet, Roy Fielding]
10414 *) When merging the main server's <Directory> and <Location> sections into
10415 a vhost, put the main server's first and the vhost's second. Otherwise
10416 the vhost can't override the main server. [Dean Gaudet] PR#717
10418 *) The <Directory> code would merge and re-merge the same section after
10419 a match was found, possibly causing problems with some modules.
10422 *) Fixed an infinite loop in mod_imap for references above the server root.
10423 [Dean Gaudet] PR#748
10425 *) mod_include cleanup showed that handle_else was being used to handle
10426 endif. It didn't cause problems, but it was cleaned up too.
10429 *) Last official synchronization of mod_rewrite with author version (because
10430 mod_rewrite is now directly developed by the author at the Apache Group):
10431 o added diff between mod_rewrite 3.0.6+ and 3.0.9
10432 minus WIN32/NT stuff, but plus copyright removement.
10434 - workaround for detecting infinite rewriting loops
10435 - fixed setting of env vars when "-" is used as subst string
10436 - fixed forced response code on redirects (PR#777)
10437 - fixed cases where r->args is ""
10438 - kludge to disable locking on pipes under braindead SunOS
10439 - fix for rewritelog in cases where remote hostname is unknown
10440 - fixed totally damaged request_rec walk-back loop
10441 o remove static from local data and add static to global ones.
10442 o replaced ugly proxy finding stuff by simple
10443 find_linked_module("mod_proxy") call.
10444 o added missing negation char on rewritelog()
10445 o fixed a few comment typos
10446 [Ralf S. Engelschall]
10448 *) Anonymous_LogEmail was logging on each subrequest.
10449 [Dean Gaudet] PR#421, PR#868
10451 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
10452 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
10453 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
10454 Additionally mod_browser now triggers during translate_name to workaround
10455 a deficiency in the header_parse phase.
10456 [Dean Gaudet] PR#875

10462 *) Properly treat <files> container like other containers in mod_info.
10463 [Marc Slemko] PR#848
10465 *) The proxy didn't treat the "Host:" keyword of the host header as case-
10466 insensitive. The proxy would corrupt the first line of a response from
10467 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
10469 *) mod_include would log some bogus values occasionally.

10472 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
10473 under Solaris 2.x (up through 2.5.1). It has been fixed.
10474 [Dean Gaudet] PR#832
10476 *) API: In HTTP/1.1, whether or not a request message contains a body
10477 is independent of the request method and based solely on the presence
10478 of a Content-Length or Transfer-Encoding. Therefore, our default
10479 handlers need to be prepared to read a body even if they don't know
10480 what to do with it; otherwise, the body would be mistaken for the
10481 next request on a persistent connection. discard_request_body()
10482 has been added to take care of that. [Roy Fielding] PR#378
10484 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
10485 release version number, such that it always increases along the
10486 same lines as our source code branching. [Roy Fielding]
10488 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
10490 Changes with Apache 1.2.1
10492 *) SECURITY: Don't serve file system objects unless they are plain files,
10493 symlinks, or directories. This prevents local users from using pipes
10494 or named sockets to invoke programs for an extremely crude form of

10498 could contain "../" allowing a local user to "publish" any file on
10499 the system. No slashes are allowed now. [Dean Gaudet]
10501 *) SECURITY: It was possible to violate the symlink Options using mod_dir
10502 (headers, readmes, titles), mod_negotiation (type maps), or
10503 mod_cern_meta (meta files). [Dean Gaudet]
10505 *) SECURITY: Apache will refuse to run as "User root" unless
10506 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
10508 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
10509 if it contained a .htaccess disallowing symlinks. This is contrary
10510 to the rule that symlink permissions are tested with the symlink
10511 options of the parent directory. [Dean Gaudet] PR#353
10513 *) CONFIG: The LockFile directive can be used to place the serializing
10514 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
10515 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
10518 *) Request processing now retains state of whether or not the request
10519 body has been read, so that internal redirects and subrequests will
10520 not try to read it twice (and block). [Roy Fielding]
10522 *) Add a placeholder in modules/Makefile to avoid errors with certain
10523 makes. [Marc Slemko]
10525 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

10531 *) Attempt to work around problems with third party libraries that do not
10532 handle high numbered descriptors (examples include bind, and
10533 solaris libc). On all systems apache attempts to keep all permanent
10534 descriptors above 15 (called the low slack line). Solaris users
10535 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
10536 which keeps all non-FILE * descriptors above 255. On all systems
10537 this should make supporting large numbers of vhosts with many open
10538 log files more feasible. If this causes trouble please report it,
10539 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
10540 [Dean Gaudet] various PRs
10542 *) Related to the last entry, network sockets are now opened before
10543 log files are opened. The only known case where this can cause
10544 problems is under Solaris with many virtualhosts and many Listen
10545 directives. But using -DHIGH_SLACK_LINE=256 described above will
10546 work around this problem. [Dean Gaudet]
10548 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and

10553 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
10554 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
10555 when a URL http://... was used in conjunction with a special

10600 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
10601 reading from one buffer and writing to another, at least until it has
10602 a custom timeout handler. [Roy Fielding and Petr Lampa]

10647 original request-line. [Roy Fielding]
10649 *) Test for error conditions before creating output header fields, since
10650 we don't want the error message to include those fields. Likewise,
10651 reset the content_language(s) and content_encoding of the response
10652 before generating or redirecting to an error message, since the new
10653 message will have its own Content-* definitions. [Dean Gaudet]

10656 and 304 responses) and err_headers_out (headers sent with all responses).
10657 Avoid the overhead of copying tables if err_headers_out is empty
10658 (the usual case). [Roy Fielding]

10661 not properly checking both the value configured by the DefaultType

10673 *) The method for determining PATH_INFO has been restored to the pre-1.2b
10674 (and NCSA httpd) definition wherein it was the extra path info beyond
10675 the CGI script filename. The environment variable FILEPATH_INFO has
10676 been removed, and instead we supply the original REQUEST_URI to any
10677 script that wants to be Apache-specific and needs the real URI path.
10678 This solves a problem with existing scripts that use extra path info
10679 in the ScriptAlias directive to pass options to the CGI script.
10682 *) The _default_ change in 1.2b10 will change the behaviour on configs
10683 that use multiple Listen statements for listening on multiple ports.
10684 But that change is necessary to make _default_ consistent with other

10697 Changes with Apache 1.2b10
10699 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
10700 to be configured via -D in Configuration. [Dean Gaudet] PR#449
10702 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
10704 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
10706 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
10707 config, in case the hostent struct returned is trash.
10708 [Chuck Murcko] PR #491
10710 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
10711 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
10713 Changes with Apache 1.2b9 [never announced]
10715 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
10716 changes and in anticipation of 1.2 final release. [Roy Fielding]
10718 *) Fix problem with scripts not receiving a SIGPIPE when client drops
10719 the connection (e.g., when user presses Stop). Apache will now stop
10720 trying to send a message body immediately after an error from write.
10721 [Roy Fielding and Nathan Kurz] PR#335
10723 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
10724 than mod_alias, and mod_alias has higher priority than mod_proxy;
10725 rearranged other modules to enhance understanding of their purpose
10726 and relative order (and maybe even reduce some overhead).
10727 [Roy Fielding and Sameer Parekh]
10729 *) Fix graceful restart. Eliminate many signal-related race
10730 conditions in both forms of restart, and in SIGTERM. See
10731 htdocs/manual/stopping.html for details on stopping and
10732 restarting the parent. [Dean Gaudet]
10734 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
10735 memory allocator to avoid a behaviour that required extra blocks to
10736 be allocated. [Dean Gaudet]
10738 *) Allow suexec to access files relative to current directory but not
10739 above. (Excluding leading / or any .. directory.) [Ken Coar]
10742 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
10743 PR#367, 368, 354, 453
10745 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
10746 while obtaining the /~user and save the username in a separate data
10747 area so that it won't be overwritten by the call to getgrgid(), and
10748 fix some misuse of the pool string allocation functions. Also fixes
10749 a general problem with parsing URL query info into args for CGI scripts.
10750 [Roy Fielding] PR#339, 367, 354, 453
10752 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
10754 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
10756 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
10757 AuthDBAuthoritative. [Marc Slemko] PR#420
10759 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
10761 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
10762 object that can't be PUT, or FOOBAR for some method FOOBAR that
10763 apache doesn't know about at all). Log 404s that occur in mod_include.
10764 [Paul Sutton, John Van Essen]
10766 *) If a soft timeout (or lingerout) occurs while trying to flush a
10767 buffer or write inside buff.c or fread'ing from a CGI's output,
10768 then the timeout would be ignored. [Roy Fielding] PR#373
10770 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
10771 parsing of headers. If the terminating empty-line CRLF occurs starting
10772 at the 256th or 257th byte of output, then Navigator will think a normal
10773 image is invalid. We are guessing that this is because their initial
10774 read of a new request uses a 256 byte buffer. We check the bytes written
10775 so far and, if we are about to tickle the bug, we instead insert a
10776 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
10778 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
10779 of an external redirection. [Roy Fielding and Paul Sutton]
10781 *) Configure would create a broken Makefile if the configuration file
10782 contained a commented-out Rule. [Roy Fielding]
10784 *) Promote per_dir_config and subprocess_env from the subrequest to the
10785 main request in mod_negotiation. In particular this fixes a bug
10786 where <Files> sections wouldn't properly apply to negotiated content.
10789 *) Fix a potential deadlock in mod_cgi script_err handling.
10790 [Ralf S. Engelschall]
10792 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
10793 [Mitchell Blank Jr]
10795 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
10796 .htaccess files because the RewriteBase was not replaced correctly.
10797 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
10798 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
10800 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
10801 1.x the settings are those of pre-1.2b8. For 2.x we include
10802 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
10803 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
10804 [Dean Gaudet] PR#336, PR#340
10806 *) Redirect did not preserve ?query_strings when present in the client's
10807 request. [Dean Gaudet]
10809 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
10811 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
10813 *) Add UnixWare compile/install instructions. [Chuck Murcko]
10815 *) Add mod_example (illustration of API techniques). [Ken Coar]
10817 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
10819 *) Improve handling of directories when filenames have spaces in them.
10822 *) For hosts with multiple IP addresses, try all additional addresses if
10823 necessary to get a connect. Fail only if hostent address list is
10824 exhausted. [Chuck Murcko]
10826 *) More signed/unsigned port fixes. [Dean Gaudet]
10828 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
10831 Changes with Apache 1.2b8
10833 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
10834 to it. [Marc Slemko]
10836 *) The addition of <Location> and <File> directives made the
10837 sub_req_lookup_simple() function bogus, so we now handle
10838 the special cases directly. [Dean Gaudet]
10840 *) We now try to log where the server is dumping core when a fatal
10841 signal is received. [Ken Coar]
10843 *) Improved lingering_close by adding a special timeout, removing the
10844 spurious log messages, removing the nonblocking settings (they
10845 are not needed with the better timeout), and adding commentary
10846 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
10847 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
10849 *) Send error messages about setsockopt failures to the server error
10850 log instead of stderr. [Roy Fielding]
10852 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
10854 *) Stopgap solution for CGI 3-second delay with server-side includes: if
10855 processing a subrequest, allocate memory from r->main->pool instead
10856 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
10857 in the middle of an SSI request. [Dean Gaudet] PR #122
10859 *) Fixed status of response when POST is received for a nonexistent URL
10860 (was sending 405, now 404) and when any method is sent with a
10861 full-URI that doesn't match the server and the server is not acting
10862 as a proxy (was sending 501, now 403). [Roy Fielding]
10864 *) Host port changed to unsigned short. [Ken Coar] PR #276
10866 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
10868 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
10870 *) Report extra info from errno with many errors that cause httpd to exit.
10871 spawn_child, popenf, and pclosef now have valid errno returns in the
10872 event of an error. Correct problems where errno was stomped on
10873 before being reported. [Dean Gaudet]
10875 *) In the proxy, if the cache filesystem was full, garbage_coll() was
10876 never called, and thus the filesystem would remain full indefinitely.
10877 We now also remove incomplete cache files left if the origin server
10878 didn't send a Content-Length header and either the client has aborted
10879 transfer or bwrite() to client has failed. [Petr Lampa]
10881 *) Fixed the handling of module and script-added header fields.
10882 Improved the interface for sending header fields and reduced
10883 the duplication of code between sending okay responses and errors.
10884 We now always send both headers_out and err_headers_out, and
10885 ensure that the server-reserved fields are not being overridden,
10886 while not overriding those that are not reserved. [Roy Fielding]
10888 *) Moved transparent content negotiation fields to err_headers_out
10889 to reflect above changes. [Petr Lampa]
10891 *) Fixed the determination of whether or not we should make the
10892 connection persistent for all of the cases where some other part
10893 of the server has already indicated that we should not. Also
10894 improved the ordering of the test so that chunked encoding will
10895 be set whenever it is desired instead of only when KeepAlive
10896 is enabled. Added persistent connection capability for most error
10897 responses (those that do not indicate a bad input stream) when
10898 accessed by an HTTP/1.1 client. [Roy Fielding]
10900 *) Added missing timeouts for sending header fields, error responses,
10901 and the last chunk of chunked encoding, each of which could have
10902 resulted in a process being stuck in write forever. Using soft_timeout
10903 requires that the sender check for an aborted connection rather than
10904 continuing after an EINTR. Timeouts that used to be initiated before
10905 send_http_header (and never killed) are now initiated only within or
10906 around the routines that actually do the sending, and not allowed to
10907 propagate above the caller. [Roy Fielding]
10909 *) mod_auth_anon required an @ or a . in the email address, not both.
10912 *) per_dir_defaults weren't set correctly until directory_walk for
10913 name-based vhosts. This fixes an obscure bug with the wrong config
10914 info being used for vhosts that share the same ip as the server.
10917 *) Improved generation of modules/Makefile to be more generic for
10918 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
10920 *) Generate makefile dependency for Configuration based on the actual
10921 name given when running the Configure process. [Dean Gaudet]
10923 *) Fixed problem with vhost error log not being set prior to
10924 initializing virtual hosts. [Dean Gaudet]
10926 *) Fixed infinite loop when a trailing slash is included after a type map
10927 file URL (extra path info). [Petr Lampa]
10929 *) Fixed server status updating of per-connection counters. [Roy Fielding]
10931 *) Add documentation for DNS issues (reliability and security), and try
10932 to explain the virtual host matching process. [Dean Gaudet]
10934 *) Try to continue gracefully by disabling the vhost if a DNS lookup
10935 fails while parsing the configuration file. [Dean Gaudet]
10937 *) Improved calls to setsockopt. [Roy Fielding]
10939 *) Negotiation changes: Don't output empty content-type in variant list;
10940 Output charset in variant list; Return sooner from handle_multi() if
10941 no variants found; Add handling of '*' wildcard in Accept-Charset.
10942 [Petr Lampa and Paul Sutton]
10944 *) Fixed overlaying of request/sub-request notes and headers in
10945 mod_negotiation. [Dean Gaudet]
10947 *) If two variants' charset quality are equal and one is the default
10948 charset (iso-8859-1), then prefer the variant that was specifically
10949 listed in Accept-Charset instead of the default. [Petr Lampa]
10951 *) Memory allocation problem in push_array() -- it would corrupt memory
10952 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
10954 *) invoke_handler() doesn't handle mime arguments in content-type
10955 [Petr Lampa] PR#160
10957 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
10960 *) Fixed problem with ErrorDocument not working for virtual hosts
10961 due to one of the performance changes in 1.2b7. [Dean Gaudet]
10963 *) Log an error message if we get a request header that is too long,
10964 since it may indicate a buffer overflow attack. [Marc Slemko]
10966 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
10967 not reject URLs without a double-slash, as per RFC2068 section 3.2.
10968 [Ken Coar] PR #146, #187
10970 *) Added table entry placeholder for new header_parser callback
10971 in all of the distributed modules. [Ken Coar] PR #191
10973 *) Allow for cgi files without the .EXE extension on them under OS/2.
10974 [Garey Smiley] PR #59
10976 *) Fixed error message when resource is not found and URL contains
10977 path info. [Petr Lampa and Dean Gaudet] PR #40
10979 *) Fixed user and server confusion over what should be a virtual host
10980 and what is the main server, resulting in access to something
10981 other than the name defined in the virtualhost directive (but
10982 with the same IP address) failing. [Dean Gaudet]
10984 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
10985 AIX; improves the redirection stuff to enable the users to generally
10986 redirect to http, https, gopher and ftp; added TIME variable for
10987 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
10988 special patterns >STRING, <STRING and =STRING to RewriteCond, which
10989 can be used in conjunction with %{TIME} or other variables to create
10990 time-dependent rewriting rules. [Ralf S. Engelschall]
10992 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
10993 Module authors may need to adjust their code for proper cleanup to take
10994 place (that is, call note_cleanups_for_fd()). This change fixes problems
10995 with file descriptors being erroneously closed when the proxy module was
10996 in use. [Ben Laurie]
10998 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
10999 initgroups() to hose the group information needed for later
11000 comparisons. [Randy Terbush]
11002 *) Remove unnecessary call to va_end() in create_argv() which
11003 caused a SEGV on some systems.
11005 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
11008 *) Clear memory allocated for listeners. [Randy Terbush]
11010 *) Improved handling of IP address as a virtualhost address and
11011 introduced "_default_" as a synonym for the default vhost config.
11012 [Dean Gaudet] PR #212
11014 Changes with Apache 1.2b7
11016 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
11018 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
11020 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
11021 - replace protocol response numbers with symbols
11022 - save variant-list into main request notes
11023 - free allocated memory from subrequests
11024 - merge notes, headers_out and err_headers_out
11026 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
11027 "HTTP/#.# ###*" to be more lenient about what we accept.
11030 *) more proxy FTP bug fixes:
11031 - Changed send_dir() to remove user/passwd from displayed URL.
11032 - Changed login error messages to be more descriptive.
11033 - remove setting of SO_DEBUG socket option
11034 - Make ftp_getrc() more lenient about multiline responses,
11035 specifically, 230 responses which don't have continuation 230-
11036 on each line). These seem to be all NT FTP servers, and while
11037 perhaps questionable, they appear to be legal by RFC 959.
11038 - Add missing kill_timeout() after transfer to user completes.
11041 *) Fixed problem where a busy server could hang when restarting
11042 after being sent a SIGHUP due to child processes not exiting.
11045 *) Modify mod_include escaping so a '\' only signifies an escaped
11046 character if the next character is one that needs
11047 escaping. [Ben Laurie]
11049 *) Eliminated possible infinite loop in mod_imap when relative URLs are
11050 used with a 'base' directive that does not have a '/' in it.
11051 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
11053 *) Reduced the default timeout from 1200 seconds to 300, and the
11054 one in the sample configfile from 400 to 300. [Marc Slemko]
11056 *) Stop vbprintf from crashing if given a NULL string pointer;
11057 print (null) instead. [Ken Coar]
11059 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
11060 [Marc Slemko and Roy Fielding]
11062 *) Fixed problem with mod_cgi-generated internal redirects trying to
11063 read the request message-body twice. [Archie Cobbs and Roy Fielding]
11065 *) Reduced timeout on lingering close, removed possibility of a blocked
11066 read causing the child to hang, and stopped logging of errors if
11067 the socket is not connected (reset by client). [Roy Fielding]
11069 *) Rearranged main child loop to remove duplication of code in
11070 select/accept and keep-alive requests, fixed several bugs regarding
11071 checking scoreboard_image for exit indication and failure to
11072 account for all success conditions and trap all error conditions,
11073 prevented multiple flushes before closing the socket; close the entire
11074 socket buffer instead of just one descriptor, prevent logging of
11075 EPROTO and ECONNABORTED on platforms where supported, and generally
11076 improved readability. [Roy Fielding]
11078 *) Extensive performance improvements. Cleaned up inefficient use of
11079 auto initializers, multiple is_matchexp calls on a static string,
11080 and excessive merging of response_code_strings. [Dean Gaudet]
11082 *) Added double-buffering to mod_include to improve performance on
11083 server-side includes. [Marc Slemko]
11085 *) Several fixes for suexec wrapper. [Randy Terbush]
11086 - Make wrapper work for files on NFS filesystem.
11087 - Fix portability problem of MAXPATHLEN.
11088 - Fix array overrun problem in clean_env().
11089 - Fix allocation of PATH environment variable
11091 *) Removed extraneous blank line is description of mod_status chars.
11094 *) Logging of errors from the call_exec routine simply went nowhere,
11095 since the logfile fd has been closed, so now we send them to stderr.
11096 [Harald T. Alvestrand]
11098 *) Fixed core dump when DocumentRoot is a CGI.
11099 [Ben Laurie, reported by geddis@tesserae.com]
11101 *) Fixed potential file descriptor leak in mod_asis; updated it and
11102 http_core to use pfopen/pfclose instead of fopen/fclose.
11103 [Randy Terbush and Roy Fielding]
11105 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
11106 as the DEC Alpha which is 64-bit but uses 32-bit ints.
11107 [Dean Gaudet and Ken Coar]
11109 *) Return a 302 response code to the client when sending a redirect
11110 due to a missing trailing '/' on a directory instead of a 301; now
11111 it is cacheable. [Markus Gyger]
11113 *) Fix condition where, if a bad directive occurs in .htaccess, and
11114 sub_request() goes first to this directory, then log_reason() will
11115 SIGSEGV because it doesn't have initialized r->per_dir_config.
11116 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
11118 *) Fix handling of lang_index in is_variant_better(). This was
11119 causing problems which resulted in the server sending the
11120 wrong language document in some cases. [Petr Lampa]
11122 *) Remove free() from clean_env() in suexec wrapper. This was nuking
11123 the clean environment on some systems.
11125 *) Tweak byteserving code (e.g. serving PDF files) to work around
11126 bugs in Netscape Navigator and Microsoft Internet Explorer.
11127 Emit Content-Length header when sending multipart/byteranges.
11130 *) Port to HI-UX/WE2. [Nick Maclaren]

11133 [Mark Bixby <markb@cccd.edu>]
11135 *) Fixed bug which caused a segmentation fault if only one argument
11136 given to RLimit* directives. [Ed Korthof]
11138 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
11140 *) Improved buffered output to the client by delaying the flush decision
11141 until the BUFF code is actually about to read the next request.
11142 This fixes a problem introduced in 1.2b5 with clients that send
11143 an extra CRLF after a POST request. Also improved chunked output
11144 performance by combining writes using writev() and removing as
11145 many bflush() calls as possible. NOTE: Platforms without writev()
11146 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
11147 or Configure, unless we have already done so. [Dean Gaudet]
11149 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
11151 *) Fixed mod_info output corruption bug introduced by buffer overflow
11152 fixes. [Dean Gaudet]
11154 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
11155 for the special case of a 304 response. [Paul Sutton]
11157 *) Improved handling of TRACE method by bypassing normal method handling
11158 and header parsing routines; fixed Allow response to always allow TRACE.
11161 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
11163 *) Cleaned-up some of the generated HTML. [Ken Coar]
11165 Changes with Apache 1.2b6
11167 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
11169 *) Fix typo introduced in fix for potential infinite loop around
11170 accept() in child_main(). This change caused the rev to 1.2b6.
11171 1.2b5 was never a public beta.
11173 Changes with Apache 1.2b5
11175 *) Change KeepAlive semantics (On|Off instead of a number), add
11176 MaxKeepAliveRequests directive. [Alexei Kosut]
11178 *) Various NeXT compilation patches, as well as a change in
11179 regex/regcomp.c since that file also used a NEXT define.
11182 *) Allow * to terminate the end of a directory match in mod_dir.
11183 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
11185 *) Don't call can_exec() if suexec_enabled. Calling this requires
11186 scripts executed by the suexec wrapper to be world executable, which
11187 defeats one of the advantages of running the wrapper. [Randy Terbush]
11189 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
11192 *) Migration from sprintf() to snprintf() to avoid buffer
11193 overflows. [Marc Slemko]
11195 *) Provide portable snprintf() implementation (ap_snprintf)
11196 as well as *cvt family. [Jim Jagielski]
11198 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
11201 *) Remove mod_fastcgi.c from the distribution. This module appears
11202 to be maintained more through the Open Market channels and should
11203 continue to be easily available at http://www.fastcgi.com/
11205 *) Fixed bug in modules/Makefile that wouldn't allow building in more
11206 than one subdirectory (or cleaning, either). [Jeremy Laidman]
11208 *) mod_info assumed that the config files were relative to ServerRoot.
11211 *) CGI scripts called as an error document resulting from failed
11212 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
11214 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
11217 *) Properly check errno to prevent display of a directory index
11218 when server receives a long enough URL to confuse stat().
11221 *) Several security enhancements to suexec wrapper. It is _highly_
11222 recommended that previously installed versions of the wrapper
11223 be replaced with this version. [Randy Terbush, Jason Dour]
11225 - ~user execution now properly restricted to ~user's home
11226 directory and below.
11227 - execution restricted to UID/GID > 100
11228 - restrict passed environment to known variables
11229 - call setgid() before initgroups() (portability fix)
11230 - remove use of setenv() (portability fix)
11232 *) Add HTTP/1.0 response forcing. [Ben Laurie]
11234 *) Add access control via environment variables. [Ben Laurie]
11236 *) Add rflush() function. [Alexei Kosut]
11238 *) remove duplicate pcalloc() call in new_connection().
11240 *) Fix incorrect comparison which could allow number of children =
11241 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
11242 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
11244 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
11245 AIX PS/2, CONVEXOS. [Jim Jagielski]
11247 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
11248 It's more portable. [Martin Kraemer]
11250 *) Replace references to make in Makefile.tmpl with $(MAKE).
11253 *) Add ProxyBlock directive w/IP address caching. Add IP address
11254 caching to NoCache directive as well. ProxyBlock works with all
11255 handlers; NoCache now also works with FTP for anonymous logins.
11256 Still more code cleanup. [Chuck Murcko]
11258 *) Add "header parse" API hook [Ben Laurie]
11260 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
11262 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
11264 *) Correctly allow access and auth directives in <Files> sections in
11265 server config files. [Alexei Kosut]
11267 *) Fix bug with ServerPath that could cause certain files to be not
11268 found by the server. [Alexei Kosut]
11270 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
11271 double-quote from text and so that it properly checks for unsupported
11272 status codes using the new index_of_response interface. [Roy Fielding]
11274 *) Multiple fixes to the lingering_close code in order to avoid being
11275 interrupted by a stray timeout, to avoid lingering on a connection
11276 that has already been aborted or never really existed, to ensure that
11277 we stop lingering as soon as any error condition is received, and to
11278 prevent being stuck indefinitely if the read blocks. Also improves
11279 reporting of error conditions. [Marc Slemko and Roy Fielding]
11281 *) Fixed initialization of parameter structure for sigaction.
11282 [mgyger@itr.ch, Adrian Filipi-Martin]
11284 *) Fixed reinitializing the parameters before each call to accept and
11285 select, and removed potential for infinite loop in accept.
11286 [Roy Fielding, after useful PR from adrian@virginia.edu]
11288 *) Fixed condition where, if a child fails to fork, the scoreboard would
11289 continue to say SERVER_STARTING forever. Eventually, the main process
11290 would refuse to start new children because count_idle_servers() will
11291 count those SERVER_STARTING entries and will always report that there
11292 are enough idle servers. [Phillip Vandry]
11294 *) Fixed bug in bcwrite regarding failure to account for partial writes.
11295 Avoided calling bflush() when the client is pipelining requests.
11296 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
11298 *) Added description of "." mode in server-status [Jim Jagielski]
11300 Changes with Apache 1.2b4
11302 *) Fix possible race condition in accept_mutex_init() that
11303 could leave a small security hole open allowing files to be
11304 overwritten in cases where the server UID has write permissions.
11307 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
11309 *) Fix portablity problem in util_script where ARG_MAX may not be
11310 defined for some systems.
11312 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
11315 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
11316 style magic #! token for better script portability. [Garey Smiley]
11318 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
11319 execution for ~userdir CGI. [Jason Dour]
11321 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
11323 *) Fix month off by one in suexec wrapper logging.
11325 Changes with Apache 1.2b3:
11327 *) Fix error in mod_cgi which could cause resources not to be properly
11328 freed, or worse. [Dean Gaudet]
11330 *) Fix find_string() NULL pointer dereference. [Howard Fear]
11332 *) Add set_flag_slot() at the request of Dirk and others.
11335 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
11337 *) Add changes to improve the error message given for invalid
11338 ServerName parameters. [Dirk vanGulik]
11340 *) Add "Authoritative" directive for Auth modules that don't
11341 currently have it. This gives admin control to assign authoritative
11342 control to an authentication scheme and allow "fall through" for
11343 those authentication modules that aren't "Authoritative" thereby
11344 allowing multiple authentication mechanisms to be chained.
11347 *) Remove requirement for ResourceConfig/AccessConfig if not using
11348 the three config file layout. [Randy Terbush]
11350 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
11352 *) Changes to suexec wrapper to fix the following problems:
11353 1. symlinked homedirs will kill ~userdirs.
11354 2. initgroups() on Linux 2.0.x clobbers gr->grid.
11355 3. CGI command lines paramters problems
11356 4. pw-pwdir for "docroot check" still the httpd user's pw record.
11357 [Randy Terbush, Jason Dour]
11359 *) Change create_argv() to accept variable arguments. This fixes
11360 a problem where arguments were not getting passed to the CGI via
11361 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
11363 *) Collapse multiple slashes in path URLs to properly apply
11364 handlers defined by <Location>. [Alexei Kosut]
11366 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
11368 *) Improve the accuracy of request duration timings by setting
11369 r->request_time in read_request_line() instead of read_request().
11372 *) Reset timeout while reading via get_client_block() in mod_cgi.c
11373 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
11375 *) Add the ability to pass different Makefile.tmpl files to Configure
11376 using the -make flag. [Rob Hartill]
11378 *) Fix coredump triggered when sending a SIGHUP to the server caused
11379 by an assertion failure, in turn caused by an uninitialised field in a
11383 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
11384 PATH_INFO from previous versions of Apache (in certain situations,
11385 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
11386 [later removed in 1.2b11]
11388 *) Add rwrite() function to API to allow for sending strings of
11389 arbitrary length. [Doug MacEachern]
11391 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
11393 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
11394 NeXT. [Jim Jagielski]
11396 *) Removed recent modification to promote the status code on internal
11397 redirects, since the correct fix was to change the default log format
11398 in mod_log_config so that it outputs the original status. [Rob Hartill]
11400 Changes with Apache 1.2b2:
11402 *) Update set_signals() to use sigaction() for setting handlers.
11403 This appears to fix a re-entrant problem in the seg_fault()
11404 bus_error() handlers. [Randy Terbush]
11406 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
11408 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
11410 *) proxy_http.c bugfixes: [Chuck Murcko]
11411 1) fixes possible NULL pointer reference w/NoCache
11412 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
11413 host would cache nothing if it was in the local domain,
11414 and the local domain was in the NoCache list)
11415 3) Adds Host: header when not available
11416 4) Some code cleanup and clarification
11418 *) mod_include.c bugfixes:
11419 1) Fixed an ommission that caused include variables to not
11420 be parsed in config errmsg directives [Howard Fear]
11421 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
11422 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
11423 4) Allow backslash-escaping to all quoted text
11424 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
11425 5) Pass variable to command line if not set in XSSI's env
11428 *) Fix infinite loop when processing Content-language lines in
11429 type-map files. [Alexei Kosut]
11431 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
11433 *) Fixed problem in set_[user|group] that prevented CGI execution
11434 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
11436 *) Added PORTING information file. [Jim Jagielski]
11438 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
11440 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
11442 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
11443 USE_FCNTL_SERIALIZED_ACCEPT was intended.
11445 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
11446 which caused problems of systems where socket s_addr is >32bits.
11448 *) Added comment to explain (r->chunked = 1) side-effect in
11449 http_protocol.c [Roy Fielding]
11451 *) Replaced use of index() in mod_expires.c with more appropriate
11452 and portable isdigit() test. [Ben Laurie]
11454 *) Updated Configure for ...
11455 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
11456 *-dg-dgux* (bad pattern match)
11457 QNX (DEF_WANTHSREGEX=yes)
11458 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
11460 *-unixware211 (new)
11461 and added some user diagnostic info. [Ben Laurie]
11463 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
11464 for better portability. [Jim Jagielski]
11466 *) Updated helpers/GuessOS for ...
11467 SCO 5 (recognize minor releases)
11468 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
11469 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
11470 IRIX64 (-sgi-irix64)
11471 ULTRIX (-unknown-ultrix)
11472 SINIX (-whatever-sysv4)
11473 NCR Unix (-ncr-sysv4)
11474 and fixed something in helpers/PrintPath [Ben Laurie]
11476 Changes with Apache 1.2b1
11478 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
11480 Changes with Apache 1.1.1
11482 *) Fixed bug where Cookie module would make two entries in the
11483 logfile for each access [Mark Cox]
11485 *) Fixed bug where Redirect in .htaccess files would cause memory
11486 leak. [Nathan Neulinger]
11488 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
11490 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
11492 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
11494 Changes with Apache 1.1.0
11496 *) Bring NeXT support up to date. [Takaaki Matsumoto]
11498 *) Bring QNX support up to date. [Ben Laurie]
11500 *) Make virtual hosts default to main server keepalive parameters.
11501 [Alexei Kosut, Ben Laurie]
11503 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
11505 *) Fix missing address family for connect, also remove unreachable statement
11506 in mod_proxy. [Ben Laurie]
11508 *) mod_env now turned on by default in Configuration.tmpl.
11510 *) Bugs which were fixed:
11511 a) yet more mod_proxy bugs [Ben Laurie]
11512 b) CGI works again with inetd [Alexei Kosut]
11513 c) Leading colons were stripped from passwords [osm@interguide.com]
11514 d) Another fix to multi-method Limit problem [jk@tools.de]
11516 Changes with Apache 1.1b4
11518 *) r->bytes_sent variable restored. [Robert Thau]
11520 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
11522 *) More possibly unsecure programs removed from the support directory.
11524 *) More mod_auth_msql authentication improvements.
11526 *) VirtualHosts based on Host: headers no longer conflict with the
11529 *) OS/2 compatibility enhancements. [Gary Smiley]
11531 *) POST now allowed to directory index CGI scripts.
11533 *) Actions now work with files of the default type.
11535 *) Bugs which were fixed:
11536 a) more mod_proxy bugs
11537 b) early termination of inetd requests
11538 c) compile warnings on several systems
11539 d) problems when scripts stop reading output early
11541 Changes with Apache 1.1b3
11543 *) Much of cgi-bin and all of cgi-src has been removed, due to
11544 various security holes found and that we could no longer support
11547 *) The "Set-Cookie" header is now special-cased to not merge multiple
11548 instances, since certain popular browsers can not handle multiple
11549 Set-Cookie instructions in a single header. [Paul Sutton]
11551 *) rprintf() added to buffer code, occurrences of sprintf removed.
11554 *) CONNECT method for proxy module, which means tunneling SSL should work.
11555 (No crypto needed) Also a NoCache config directive.
11557 *) Several API additions: pstrndup(), table_unset() and get_token()
11558 functions now available to modules.
11560 *) mod_imap fixups, in particular Location: headers are now complete
11563 *) New "info" module which reports on installed module set through a
11564 special URL, a la mod_status.
11566 *) "ServerPath" directive added - allows for graceful transition
11567 for Host:-header-based virtual hosts.
11569 *) Anonymous authentication module improvements.
11571 *) MSQL authentication module improvements.
11573 *) Status module design improved - output now table-based. [Ben Laurie]
11575 *) htdigest utility included for use with digest authentication
11578 *) mod_negotiation: Accept values with wildcards to be treated with
11579 less priority than those without wildcards at the same quality
11580 value. [Alexei Kosut]
11582 *) Bugs which were fixed:
11583 a) numerous mod_proxy bugs
11584 b) CGI early-termination bug [Ben Laurie]
11585 c) Keepalives not working with virtual hosts
11586 d) RefererIgnore problems
11587 e) closing fd's twice in mod_include (causing core dumps on
11588 Linux and elsewhere).
11590 Changes with Apache 1.1b2
11593 a) core dumps in mod_digest
11594 b) truncated hostnames/ip address in the logs
11595 c) relative URL's in mod_imap map files
11597 Changes with Apache 1.1b1
11599 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
11601 Changes with Apache 1.0.3
11603 *) Internal redirects which occur in mod_dir.c now preserve the
11604 query portion of a request (the bit after the question mark).
11607 *) Escape active characters '<', '>' and '&' in html output in
11608 directory listings, error messages and redirection links.
11611 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
11613 *) Fix for POSIX compliance in waiting for processes in alloc.c.
11616 *) setsockopt no longer takes a const declared argument [Martijn Koster]
11618 *) Reset timeout timer after each successful fwrite() to the network.
11619 This patch adds a reset_timeout() procedure that is called by
11620 send_fd() to reset the timeout ever time data is written to the net.
11623 *) timeout() signal handler now checks for SIGPIPE and reports
11624 lost connections in a more user friendly way. [Rob Hartill]
11626 *) Location of the "scoreboard" file which used to live in /tmp is
11627 now configurable (for OSes that can't use mmap) via ScoreBoardFile
11628 which works similar to PidFile (in httpd.conf) [Rob Hartill]
11630 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
11632 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
11633 which caused a SEGV with cookies enabled
11635 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
11638 *) Log the UNIX textual error returned by some system calls, in
11639 particular errors from accept() [David Robinson]
11641 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
11643 Changes with Apache 1.0.2
11645 *) patch to get Apache compiled on UnixWare 2.x, recommended as
11646 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
11648 *) Fix get_basic_auth_pw() to set the auth_type of the request.
11651 *) past changes to http_config.c to only use the
11652 setrlimit function on systems defining RLIMIT_NOFILE
11653 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
11654 for SUNOS and prototypes the needed functions.
11656 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
11659 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
11661 *) Merge multiple headers from CGI scripts instead of taking last
11662 one. [David Robinson]
11664 *) Add support for SCO 5. [Ben Laurie]
11666 Changes with Apache 1.0.1
11668 *) Silence mod_log_referer and mod_log_agent if not configured
11671 *) Recursive includes can occur if the client supplies PATH_INFO data
11672 and the server provider uses relative links; as file.html
11673 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
11675 *) The replacement for initgroups() did not call {set,end}grent(). This
11676 had two implications: if anything else used getgrent(), then
11677 initgroups() would fail, and it was consuming a file descriptor.
11680 *) On heavily loaded servers it was possible for the scoreboard to get
11681 out of sync with reality, as a result of a race condition.
11682 The observed symptoms are far more Apaches running than should
11683 be, and heavy system loads, generally followed by catastrophic
11684 system failure. [Ben Laurie]
11686 *) Fix typo in license. [David Robinson]
11688 Changes with Apache 1.0.0 23 Nov 1995
11690 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
11692 Changes with Apache 0.8.16 05 Nov 1995
11694 *) New man page for 'httpd' added to support directory [David Robinson]
11696 *) .htgroup files can have more than one line giving members for a
11697 given group (each must have the group name in front), for NCSA
11698 back-compatibility [Robert Thau]
11700 *) Mutual exclusion around accept() is on by default for SVR4 systems
11701 generally, since they generally can't handle multiple processes in
11702 accept() on the same socket. This should cure flaky behavior on
11703 a lot of those systems. [David Robinson]
11705 *) AddType, AddEncoding, and AddLanguage directives take multiple
11706 extensions on a single command line [David Robinson]
11708 *) UserDir can be disabled for a given virtual host by saying
11709 "UserDir disabled" in the <VirtualHost> section --- it was a bug
11710 that this didn't work. [David Robinson]
11712 *) Compiles on QNX [Ben Laurie]
11714 *) Corrected parsing of ctime time format [David Robinson]
11716 *) httpd does a perror() before exiting if it can't log its pid
11717 to the PidFile, to make diagnosing the error a bit easier.
11720 *) <!--#include file="..."--> can no longer include files in the
11721 parent directory, for NCSA back-compatibility. [David Robinson]
11723 *) '~' is *not* escaped in URIs generated for directory listings
11726 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
11728 *) Fixed bug involving handling URIs with escaped %-characters
11729 in redirects [David Robinson]
11731 Changes with Apache 0.8.15 14 Oct 1995
11733 *) Switched to new, simpler license
11735 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
11737 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
11739 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
11741 *) Correctly handles internal redirects to files with names containing '%'
11744 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
11746 *) Use geteuid() rather than getuid() to see if we have root privilege,
11747 so that server correctly resets privilege if run setuid root. [Andrew
11750 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
11753 *) Fix relative URLs in imagemap files [Randy Terbush]
11755 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
11758 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
11759 entries all name the same one. [David Robinson]
11761 *) Fix directory listings with filenames containing unusual characters
11764 *) Better URI-escaping for generated URIs in directories with filenames
11765 containing unusual characters [Ben Laurie]
11767 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
11769 *) Unblock alarms on error return from spawn_child() [David Robinson]
11771 *) Sample Config files have extra note for SCO users [Ben Laurie]
11773 *) Configuration has note for HP-UX users [Rob Hartill]
11775 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
11777 *) Nuked bogus #define in httpd.h [David Robinson]
11779 *) Better test for whether a system has setrlimit() [David Robinson]
11781 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
11783 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
11786 Changes with Apache 0.8.14 19 Sep 1995
11788 *) Compiles on SCO ODT 3.0 [Ben Laurie]
11790 *) AddDescription works (better) [Ben Laurie]
11792 *) Leaves an intelligible error diagnostic when it can't set group
11793 privileges on standalone startup [Andrew Wilson]
11795 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
11796 that machine, which claims to be BSD but does not support RLIMIT.
11799 *) gcc -Wall no longer complains about an unused variable when util.c
11800 is compiled with -DMINIMAL_DNS [Andrew Wilson]
11802 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
11804 Changes with Apache 0.8.13 07 Sep 1995
11806 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
11808 *) Have built-in imagemap code recognize & honor Point directive [James
11811 *) Generate cleaner directory listings in directories with a mix of
11812 long and short filenames [Rob Hartill]
11814 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
11816 *) Properly default ServerName for virtual servers [Robert Thau]
11818 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
11819 Paul Richards and a cast of thousands...]
11821 *) On self-identified BSD systems (we don't try to guess any more),
11822 allocate a few extra file descriptors per virtual host with setrlimit,
11823 if we can, to avoid running out. [Randy Terbush]
11825 *) Write 22-character lock file name into buffer with enough space
11826 on startup [Konstantin Olchanski]
11828 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
11831 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
11833 *) Suppress -Wall warning by initializing variable in negotiation code
11834 [Tobias Weingartner]
11836 Changes with Apache 0.8.12 31 Aug 1995
11838 *) Doesn't pause three seconds after including a CGI script which is
11839 too slow to die off (this is done by not even trying to kill off
11840 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
11841 after the entire document has been processed). [Robert Thau]
11843 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
11845 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
11847 *) Allows .htaccess files to override <Directory> sections naming the
11848 same directory [David Robinson]
11850 *) Removed an efficiency hack in sub_req_lookup_uri which was
11851 causing certain extremely marginal cases (e.g., ScriptAlias of a
11852 *particular* index.html file) to fail. [David Robinson]
11854 *) Doesn't log an error when the requested URI requires
11855 authentication, but no auth header line was supplied by the
11856 client; this is a normal condition (the client doesn't no auth is
11857 needed here yet). [Robert Thau]
11859 *) Behaves more sanely when the name server loses its mind [Sean Welch]
11861 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
11863 *) RFC931 code no longer passes out name of prior clients on current
11864 requests if the current request came from a server that doesn't
11865 do RFC931. [David Robinson]
11867 *) Configuration script accepts "Module" lines with trailing whitespace.
11870 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
11872 *) Cleaned up comments in mod_cgi.c [Robert Thau]
11874 Changes with Apache 0.8.11 24 Aug 1995
11876 *) Wildcard <Directory> specifications work. [Robert Thau]
11878 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
11880 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
11881 the file being requested itself, in addition to the directories leading
11882 up to it. [Robert Thau]
11884 *) Logs access failures due to symlink checks or invalid client address
11885 in the error log [Roy Fielding, Robert Thau]
11887 *) Symlink checks deal correctly with systems where lstat of
11888 "/path/to/some/link/" follows the link. [Thau, Fielding]
11890 *) Doesn't reset DirectoryIndex to 'index.html' when
11891 other directory options are set in a .htaccess file. [Robert Thau]
11893 *) Clarified init code and nuked bogus warning in mod_access.c
11894 [Florent Guillaume]
11896 *) Corrected several directives in sample srm.conf
11897 --- includes corrections to directory indexing icon-related directives
11898 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
11899 icons for encodings right, and turning on AddEncoding by default).
11902 *) Corrected descriptions of args to AddIcon and AddAlt in command table
11905 *) INSTALL & README mention "contributed modules" directory [Brian
11908 *) Fixed English in the license language... "for for" --> "for".
11911 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
11912 mod_alias.c, merging it almost completely with handling of Alias, and
11913 adding a 'notes' field to the request_rec which allows the CGI module
11914 to discover whether the Alias module has put this request through
11915 ScriptAlias (which it needs to know for back-compatibility, as the old
11916 NCSA code did not check Options ExecCGI in ScriptAlias directories).
11919 Changes with Apache 0.8.10 18 Aug 1995
11921 *) AllowOverride applies to the named directory, and not just
11922 subdirectories. [David Robinson]
11924 *) Do locking for accept() exclusion (on systems that need it)
11925 using a special file created for the purpose in /usr/tmp, and
11926 not the error log; using the error log causes real problems
11927 if it's NFS-mounted; this is known to be the cause of a whole
11928 lot of "server hang" problems with Solaris. [David Robinson;
11929 thanks to Merten Schumann for help diagnosing the problem].
11931 Changes with Apache 0.8.9 12 Aug 1995
11933 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
11935 *) Nested includes see environment variables of the including document,
11936 for NCSA bug-compatibility (some sites have standard footer includes
11937 which try to print out the last-modified date). [Eric Hagberg/Robert
11940 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
11941 URI as a CGI script, even if it would have been treated as something
11942 else if requested directly, for NCSA back-compatibility. (Note that
11943 this means that people who know the name of the script can see the
11944 code just by asking for it). [Robert Thau]
11946 *) New version of dbmmanage script included in support directory as
11949 *) Check if scoreboard file couldn't be opened, and say so, rather
11950 then going insane [David Robinson]
11952 *) POST to CGI works on A/UX [Jim Jagielski]
11954 *) AddIcon and AddAlt commands work properly [Rob Hartill]
11956 *) NCSA server push works properly --- the Arena bug compatibility
11957 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
11958 if you still want the workaround). [Rob Hartill]
11960 *) If client didn't submit any Accept-encodings, ignore encodings in
11961 content negotiation. (NB this will all have to be reworked anyway
11962 for the new HTTP draft). [Florent Guillaume]
11964 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
11966 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
11968 *) Give Redirect priority over Alias, for NCSA bug compatibility
11971 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
11972 paralleling earlier bug fix for CGI [David Robinson]
11974 *) If DBM auth is improperly configured, report a server error and don't
11977 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
11978 it seems to work well enough without it (even in a 10 hits/sec
11979 workout), and the overhead for the locking under A/UX is
11980 alarmingly high (though it is very low on other systems).
11981 [Eric Hagberg, Jim Jagielski]
11983 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
11985 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
11986 Behlendorf/Eric Hagberg]
11988 *) More improvements to default Configuration for A/UX [Jim Jagielski]
11990 *) Compiles clean on NEXT [Rob Hartill]
11992 *) Compiles clean on SGI [Robert Thau]
11994 Changes with Apache 0.8.8 08 Aug 1995
11996 *) SunOS library prototypes now never included unless explicitly
11997 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
11998 people using GNU libc on SunOS are screwed by prototypes for the
12001 (Those who wish to compile clean with gcc -Wall on a standard
12002 SunOS setup need the prototypes, and may obtain them using
12003 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
12004 with nonstandard libraries are presumably competent to make their
12007 *) Strips trailing '/' characters off both args to the Alias command,
12008 to make 'Alias /foo/ /bar/' work.
12010 Changes with Apache 0.8.7 03 Aug 1995
12012 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
12013 [reported by David Robinson]
12015 *) Compiles clean on OSF/1 [David Robinson]
12017 *) Added some of the more recent significant changes (AddLanguage stuff,
12018 experimental LogFormat support) to CHANGES file in distribution root
12021 Changes with Apache 0.8.6 02 Aug 1995
12023 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
12024 (If you actually wanted a conditional GET which bypassed the cache, you
12025 couldn't get it). [Reported by Roy Fielding]
12027 *) Properly terminate headers on '304 Not Modified' replies to conditional
12028 GETs --- no browser we can find cares much, but the CERN proxy chokes.
12029 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
12031 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
12033 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
12034 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
12035 and older versions don't set the __SUNPRO_C preprocessor variable). On
12036 all other systems, these are never used anyway. [Reported by Mark Cox].
12038 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
12040 Changes with Apache 0.8.5 01 Aug 1995
12042 *) Added last-minute configurable log experiment, as optional module
12044 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
12045 properly. (One-line fix to http_protocol.c).
12047 *) Work around bogus behavior when reloading from Netscape.
12048 It's Netscape's bug --- for some reason they expect a request with
12049 If-modified-since: to not function as a conditional GET if it also
12050 comes with Pragma: no-cache, which is way out of line with the HTTP
12051 spec (according to Roy Fielding, the redactor).
12053 *) Added parameter to set maximum number of server processes.
12055 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
12058 *) IdentityCheck bugfix [Chuck Murcko].
12060 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
12062 *) More sample config file corrections; add extension to AddType for
12063 *.asis, move AddType generic description to its proper place, and
12064 fix miscellaneous typos. [ Alexei Kosut ]
12066 *) Deleted the *other* reference to the regents from the Berkeley
12067 legal disclaimer (everyplace).
12069 *) Nuked Shambhala name from src/README; had already cleaned it out
12070 of everywhere else.
12072 Changes with Apache 0.8.4
12074 *) Changes to server-pool management parms --- renamed current
12075 StartServers to MinSpareServers, created separate StartServers
12076 parameter which means what it says, and renamed MaxServers to
12077 MaxSpareServers (though the old name still works, for NCSA 1.4
12078 back-compatibility). The old names were generally regarded as
12079 too confusing. Also altered "docs" in sample config files.
12081 *) More improvements to default config files ---
12082 sample directives (commented out) for XBitHack, BindAddress,
12083 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
12084 defaults, AddTypes for send-as-is and imagemap magic types, and
12085 improvements to samples for DirectoryIndex [Alexei Kosut]
12087 *) Yet more improvements to default config files --- changes to
12088 Alexei's sample AddLanguage directives, and sample LanguagePriority
12089 [ Florent Guillaume ]
12091 *) Set config file locations properly if not set in httpd.conf
12094 *) Don't escape URIs in internal redirects multiple times; don't
12095 do that when translating PATH_INFO to PATH_TRANSLATED either.
12098 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
12100 Changes with Apache 0.8.3
12102 *) Edited distribution README to *briefly* summarize installation
12103 procedures, and give a pointer to the INSTALL file in the src/
12106 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
12107 recent NCSA distributions.
12109 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
12110 exist for the same directory, use both and don't segfault. [Reported
12113 *) Proper makefile dependencies [David Robinson]
12115 *) Note (re)starts in error log --- reported by Rob Hartill.
12117 *) Only call no2slash() after get_path_info() has been done, to
12118 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
12119 reported by Andrew Wilson, though this one is probably a real bug]
12121 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
12122 dump core when Referer is not supplied. [Randy Terbush]
12124 *) Lightly edited sample config files to refer people to our documentation
12125 instead of NCSA's, and to list Rob McCool as *original* author (also
12126 deleted his old, and no doubt non-functional email address). Would be
12127 nice to have examples of new features...
12129 Changes with Apache 0.8.2 19 Jul 1995
12131 *) Added AddLanuage code [Florent Guillaume]
12133 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
12135 *) All sorts of problems when MultiViews finds a directory. It would
12136 be nice if mod_dir.c was robust enough to handle that, but for now,
12137 just punt. [reported by Brian Behlendorf]
12139 *) Wait for all children on restart, to make sure that the old socket
12140 is gone and we can reopen it. [reported by Randy Terbush]
12142 *) Imagemap module is enabled in default Configuration
12144 *) RefererLog and UserAgentLog modules properly default the logfile
12147 *) Mark Cox's mod_cookies added to the distribution as an optional
12148 module (commented out in the default Configuration, and noted as
12149 an experiment, along with mod_dld). [Mark Cox]
12151 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
12153 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
12155 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
12157 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
12160 Changes with Apache 0.8.1
12162 *) New imagemap module [Randy Terbush]
12164 *) Replacement referer log module with NCSA-compatible RefererIgnore
12165 [Matthew Gray again]
12167 *) Don't mung directory listings with very long filenames.
12168 [Florent Guillaume]
12170 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
12172 *) New config script. See INSTALL for info. [Robert Thau]
12174 *) Scoreboard mechanism for regulating the number of extant server
12175 processes. MaxServers and StartServers defaults are the same as
12176 for NCSA, but the meanings are slightly different. (Actually,
12177 I should probably lower the MaxServers default to 10).
12179 Before asking for a new connection, each server process checks
12180 the number of other servers which are also waiting for a
12181 connection. If there are more than MaxServers, it quietly dies
12182 off. Conversely, every second, the root, or caretaker, process
12183 looks to see how many servers are waiting for a new connection;
12184 if there are fewer than StartServers, it starts a new one. This
12185 does not depend on the number of server processes already extant.
12186 The accounting is arranged through a "scoreboard" file, named
12187 /tmp/htstatus.*, on which each process has an independent file
12188 descriptor (they need to seek without interference).
12190 The end effect is that MaxServers is the maximum number of
12191 servers on an *inactive* server machine, but more will be forked
12192 off to handle unusually heavy loads (or unusually slow clients);
12193 these will die off when they are no longer needed --- without
12194 reverting to the overhead of full forking operation. There is a
12195 hard maximum of 150 server processes compiled in, largely to
12196 avoid forking out of control and dragging the machine down.
12197 (This is arguably too high).
12199 In my server endurance tests, this mechanism did not appear to
12200 impose any significant overhead, even after I forced it to put the
12201 scoreboard file on a normal filesystem (which might have more
12202 overhead than tmpfs). [Robert Thau]
12204 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
12207 *) Read .htaccess files even in directory with <Directory> section.
12208 (Former incompatibility noted on mailing list, now fixed). [Robert
12211 *) "HEAD /" gives the client a "Bad Request" error message, rather
12212 than trying to send no body *and* no headers. [Cliff Skolnick].
12214 *) Don't produce double error reports for some very obscure cases
12215 mainly involving auth configuration (the "all modules decline to
12216 handle" case which is a sure sign of a server bug in most cases,
12217 but also happens when authentication is badly misconfigured).
12220 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
12221 it's *for*, and this sort of thing really shouldn't be cluttering
12222 up the Makefile). [Robert Thau]
12224 *) Incidental code cleanups in http_main.c --- stop dragging
12225 sa_client around; just declare it where used. [Robert Thau]
12227 *) Another acc-related fix. (It doesn't like const char
12228 in some places...). [Mark Cox]
12230 Changes with Shambhala 0.6.1 13 Jul 1995
12232 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
12233 Also, fixed auth typo in http_protocol.c unmasked by this fix.
12235 *) Compiles clean with acc on SunOS [Paul Sutton]
12237 *) Reordered modules in modules.c so that Redirect takes priority
12238 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
12239 believe it or not, he has an actual site with a ScriptAlias and
12240 a Redirect declared for the *exact same directory*. Even *my*
12241 compatibility fetish wouldn't motivate me to fix this if the fix
12242 required any effort, but it doesn't, so what the hey.
12244 *) Fixed to properly default several server_rec fields for virtual
12245 servers from the corresponding fields in the main server_rec.
12246 [Cliff Skolnick --- 'port' was a particular irritant].
12248 *) No longer kills off nph- child processes before they are
12249 finished sending output. [Matthew Gray]
12251 Changes with Shambhala 0.6.0 10 Jul 1995
12253 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
12254 the connection to the client in an "aborted" state, but otherwise
12255 allow whatever handlers are running to clean up. hard_timeout()s
12256 abort the request in progress completely; anything not tied to some
12257 resource pool cleanup will leak. They're still around because I
12258 haven't yet come up with a more elegant way of handling
12259 timeouts when talking to something that isn't the client. The
12260 default_handler and the dir_handler now use soft timeouts, largely
12261 so I can test the feature. [Robert Thau]
12263 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
12264 the case of log handlers dying prematurely is probably handled VERY
12265 gracelessly at this point, and if the logger stops reading input,
12266 the server will hang. (It is known to correctly restart the
12267 logging process on server restart; this is (should be!) going through
12268 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
12269 script). [Robert Thau]
12271 *) asis files supported (new module). [Robert Thau]
12273 *) IdentityCheck code is compiled in, but has not been tested. (I
12274 don't know anyone who runs identd). [Robert Thau]
12276 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
12277 came in with the request, for NCSA bug-compatibility. [Robert Thau]
12279 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
12281 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
12282 as timeouts are not in scope. [Robert Thau]
12284 *) quoted-string args in config files now handled correctly (doesn't drop
12285 the last character). [Robert Thau; reported by Randy Terbush]
12287 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
12288 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
12290 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
12291 default default type); the former default default behavior when all
12292 type-checkers defaulted had been a core dump. [Paul Sutton]
12294 *) Copy filenames out of the struct dirent when indexing
12295 directories. (On Linux, readdir() returns a pointer to the same
12296 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
12298 Changes with Shambhala 0.5.3 [not released]
12300 *) Default response handler notes "file not found" in the error log,
12301 if the file was not found. [Cliff Skolnick].
12303 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
12304 code no longer sets up bogus PATH_INFO which fakes out the directory
12305 handler). [Cliff Skolnick]
12307 Changes with Shambhala 0.5.2 06 Jul 1995
12309 *) Changes to http_main.c --- root server no longer plays silly
12310 games with SIGCHLD, and so now detects and replaces dying
12311 children. Child processes just die on SIGTERM, without taking
12312 the whole process group with them. Potential problem --- if any
12313 child process refuses to die, we hang in restart.
12314 MaxRequestsPerChild may still not work, but it certainly works
12315 better than it did before this! [Robert Thau]
12317 *) mod_dir.c bug fixes: ReadmeName and HeaderName
12318 work (or work better, at least); over-long description lines
12319 properly terminated. [Mark Cox]
12321 *) http_request.c now calls unescape_url() more places where it
12322 should [Paul Sutton].
12324 *) More directory handling bugs (reported by Cox)
12325 Parent Directory link is now set correctly. [Robert Thau]
12327 Changes with Shambhala 0.5.1 04 Jul 1995
12329 *) Generalized cleanup interface in alloc.c --- any function can be
12330 registered with alloc.c as a cleanup for a resource pool;
12331 tracking of files and file descriptors has been reimplemented in
12332 terms of this interface, so I can give it some sort of a test.
12335 *) More changes in alloc.c --- new cleanup_for_exec() function,
12336 which tracks down and closes all file descriptors which have been
12337 registered with the alloc.c machinery before the server exec()s a
12338 child process for CGI or <!--#exec-->. CGI children now get
12339 started with exactly three file descriptors open. Hopefully,
12340 this cures the problem Rob H. was having with overly persistent
12341 CGI connections. [Robert Thau]
12343 *) Mutual exclusion around the accept() in child_main() --- this is
12344 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
12345 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
12346 This uses fcntl(F_SETLK,...) on the error log descriptor because
12347 flock() on that descriptor won't work on systems which have BSD
12348 flock() semantics, including (I think) Linux 1.3 and Solaris.
12350 This does work on SunOS (when the server is idle, only one
12351 process in the pool is waiting on accept()); it *ought* to work
12352 on the other systems. [Robert Thau]
12354 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
12356 *) sizeof(*sa_client) bugfix from [Rob Hartill]
12358 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
12360 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
12361 be unnecessary if I go to the revised timeout-handling scheme).
12364 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
12365 string) even if none came in with the request. [Robert Thau]
12367 *) CHANGES file added to distribution ;-).
12369 Changes with Shambhala 0.4.5
12371 *) mod_dld --- early dynamic loading support [rst]
12372 *) Add wildcard content handlers for XBITHACK; default_hander now
12373 invoked with that mechanism (as a handler hanging off mod_core) [rst]
12374 *) XBITHACK supported as a wildcard content-handler, and
12375 configurable at run-time (not just at compile time, as in the
12376 "patchy server" releases) [rst]
12378 Changes with Shambhala 0.4.4 30 Jun 1995
12380 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
12381 *) Handle Addtype x/y .z [rst, reported by Cox]
12383 Changes with Shambhala 0.4.3
12385 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
12386 synonymous [rst, terbush]
12388 Changes with Shambhala 0.4.1 28 Jun 1995
12390 *) First-cut virtual host implementation; some refit in the config
12391 reading code, and log management, was necessary to support this [rst]
12392 *) Sub-pool machinery, originally added to avoid excessive storage
12393 allocation on listings of large directories (which turned out to
12394 be the problem that the 0.3 storage accounting was added to
12395 find). Subrequests and mod_dir changed to use subpools. [rst]
12396 *) More memory debugging --- free list consistency checks. [rst]
12397 *) Added err_headers to request_rec, with support elsewhere [rst]
12398 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
12400 Changes with Shambhala 0.3 19 Jun 1995
12402 *) Switch ONE_PROCESS to a runtime command-line option (-X)

12420 Changes with Shambhala 0.1 12 Jun 1995
12422 Major rewrite of the pre-existing "patchy server" codebase, by
12423 Robert Thau (rst). Significant portions of the server code, such
12424 as configuration-file handling and HTTP authentication support,
12425 were ripped out and rewritten from scratch. Code that was not
12426 completely rewritten was significantly altered.
12428 Major changes with this release include:
12430 *) Introduction of the module API; in request handling, the central
12431 machinery just dispatches to various modules, which actually do
12432 most of the work. Configuration handling is similar --- modules
12433 declare their own commands, and the central machinery just
12434 dispatches to them.
12436 API features from shambhala/0.1 were substantially unchanged in
12437 Apache 1.0 and 1.1. (1.0 API features not yet present in this
12438 release, such as wildcard handlers and subpools, were added in
12439 subsequent Shambhala releases, and were also generally rst's
12442 *) This release included the following modules:
12444 mod_access (access control --- allow and deny directives),
12445 mod_alias (Alias and Redirect commands),
12446 mod_auth (straight HTTP authentication, based on flat-files)
12447 mod_auth_dbm (same, with dbm files)
12448 mod_cgi (CGI scripts and, in this release, ScriptAlias)
12449 mod_common_log (CLF access logs; later renamed mod_log_common)
12450 mod_dir (directory indexing)
12451 mod_include (server-side includes)
12452 mod_mime (AddType directives)
12453 mod_negotiation (content negotiation)
12454 mod_userdir (support for users' public_html directories)
12456 It also included a mod_ai_backcompat, which was a private hack
12457 for back-compatibility with rst's own AI-lab servers.
12459 All of these modules were substantially complete, and functional
12460 or nearly so (a few, which implemented features not in use at
12461 Thau's site, required patches of a few lines).
12463 *) sub-request machinery, to allow modules to determine how other
12464 modules would assign MIME types to a given file, or optionally
12465 serve its content (this is heavily used by mod_dir, mod_include
12466 and mod_negotiation).
12468 *) Resource pool system for keeping track of memory allocated and
12469 files opened in service of a particular request. Much of the
12470 code in the modules (when they weren't rewrites) was adjusted to
12471 replace a pervasive convention of using fixed-size buffers on
12472 the stack with an equally pervasive convention of using memory
12473 allocated with palloc().
12475 *) Reorganization of data structures associated with a given
12476 request to eliminate use of global variables and the troublesome
12477 unmunge_name function (used in NCSA and early Apache releases to
12478 attempt to determine the URI which mapped to a given filename
12479 --- a difficult proposition, given that it is easy to produce
12480 setups in which multiple URIs map to the same file).
12482 *) Source files renamed and rearranged
12484 *) Very simple pre-forking behavior --- parent process forked off a
12485 fixed number of children, and then just waited for SIGHUP.
12487 *) Other more minor changes too numerous to list.
12489 This release included modified versions of a lot of code from the
12490 Apache 0.6.4 public release, plus an early pre-forking patch
12491 codeveloped by Robert Thau and Rob Hartill.
12493 Changes with Apache 0.7.3 20 Jun 1995
12495 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
12496 were incorporated by Rob Hartill on the main branch while Robert Thau
12497 worked on the Shambhala rewrite above. Most were merged into the
12498 Shambala architecture after Apache 0.8.0.
12500 Changes with Apache 0.6.4 13 May 1995
12502 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
12505 Changes with Apache 0.5.1 10 Apr 1995

12512 Changes with Apache 0.3 24 Mar 1995
12514 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
12517 Changes with Apache 0.2 18 Mar 1995
12519 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
12520 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
12521 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
