1 Changes with Apache 2.1.0-dev
3 [Remove entries to the current 2.0 section below, when backported]
5 *) Add code to buildconf that produces an httpd.spec file from
6 httpd.spec.in, using build/get-version.sh from APR.
9 *) ssl_toolkit_compat.h and code fixes to build clean on SSLC.
10 [William Rowe, Madhusudan Mathihalli]
12 *) Fix the inability to log errors like exec failure in
13 mod_ext_filter/mod_cgi script children. This was broken after
14 such children stopped inheriting the error log handle.
17 *) Fix a compile failure with recent OpenSSL and picky compilers
18 (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
20 *) Fix a build problem with passing unsupported --enable-layout
21 args to apr and apr-util. This broke binbuild.sh as well as
22 user-specified layout parameters. PR 18649 [Justin Erenkrantz,
25 *) ap_get_mime_headers_core: allocate space for the trailing null
26 when folding is in effect.
27 PR 18170 [Peter Mayne <PeterMayne@SPAM_SUX.ap.spherion.com>]
29 *) Do not bypass output filters when redirecting subrequests internally.
30 PR 17629. [André Malo]
32 *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
33 the INCLUDE path to be defined properly.
34 PR 11310. [Geoff Thrope <geoff@geoffthorpe.net>]
36 *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
38 *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
39 autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc).
40 [Geoff Thorpe <geoff@geoffthorpe.net>]
42 *) ssl session caching(shmht) : Fix a SEGV problem with SHMHT session
44 [Andreas Leimbacher <andreasl67@yahoo.de>, Madhusudan Mathihalli]
46 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
47 [Ian Holsman, André Malo]
49 *) mod_negotiation: quality values are now parsed independent from
50 the current locale. level values are now really parsed as integers.
51 PR 17564. [André Malo]
53 *) Linux 2.4+: enable coredumps when Apache is started as root
54 if CoreDumpDir is configured [Greg Ames]
56 *) Added the WindowsSocketsWorkaround directive for Windows NT/2000/XP
57 to work around problems with certain VPN and Firewall products that
58 have buggy AcceptEx implementations.
59 [Allan Edwards w/ suggestions from Bill Stoddard & Bill Rowe]
61 *) Unescape the supplied wildcard pattern in mod_autoindex. Otherwise
62 the pattern will not always match as desired. PR 12596.
65 *) mod_autoindex now emits and accepts modern query string parameter
66 delimiters (;). Thus column headers no longer contain unescaped
67 ampersands. PR 10880 [André Malo]
69 *) Extend mod_negotiation to evaluate the environment variables
70 no-gzip and gzip-only-text/html the same way as mod_deflate does.
73 *) mod_rewrite: Fix some problems reporting errors with mapping
74 programs (RewriteMap prg:/something). [Jeff Trawick]
76 *) When using Redirect in directory context, append requested query
77 string if there's no one supplied by configuration. PR 10961.
80 *) Fix mod_rewrite's handling of absolute URIs. The escaping routines
81 now work scheme dependent and the query string will only be
82 appended if supported by the particular scheme. [André Malo]
84 *) Return 413 if chunk-ext-header is too long rather than reading from
85 the truncated line. PR 15857. [Justin Erenkrantz]
87 *) If mod_mime_magic does not know the content-type, do not attempt to
88 guess. PR 16908. [Andrew Gapon <agapon@telcordia.com>]
90 *) Allow restart of httpd to occur even with syntax errors in the config
91 file. PR 16813. [Justin Erenkrantz]
93 *) Use APR_LAYOUT instead of APACHE_LAYOUT in configure. PR 15679.
96 *) Remove files on 'make distclean' that should be. PR 15592.
99 *) Allow apachectl to perform status with links and elinks as well.
102 *) Extend the SetEnvIf directive to capture subexpressions of the
103 matched value. [André Malo]
105 *) mod_log_config change optional hook to return previous handler
108 *) Forward port of mod_actions' ability to handle arbitrary methods
109 with the Script directive. [André Malo]
111 *) Let suexec send a message to stderr, if it failed or its policy
112 was violated. This message appears in the error log and allows
113 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
115 *) Modify buildconf to copy all required files into httpd's tree.
116 [Thom May <thom@planetarytramp.net>]
118 *) Allow mod_dav to do weak entity comparison functions.
121 *) mod_negotiation: Introduce "prefer-language" environment variable,
122 which allows to influence the negotiation process on request basis
123 to prefer a certain language. [André Malo]
125 *) Added AllowEncodedSlashes directive which permits request URIs
126 to encode '/' as '%2f' and pass it to scripts in path-info without
127 triggering the 'no encoded slashes anywhere' legacy rule.
128 PR 543, 2389, 3581, 3589, 5687, 7066, 7865, 14639. [Ken Coar]
130 *) Move RFC 1413 ident requests from core to new module mod_ident.
133 *) Add mod_authz_owner - a forward port of "Require file-owner"
134 and "Require file-group", which was already present in version
137 *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
140 *) Replace some of the mutex locking in the worker MPM with
141 atomic operations for higher concurrency. [Brian Pane]
143 *) Allow 'make depend' to work with non-GCC compilers.
146 *) If an httpd.conf has commented out AddModule directives,
147 apxs -i -a will add an un-commented AddModule directive for
148 the new module, which breaks the config.
149 PR: 11212 [Joe Orton]
151 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
153 *) Move the check of the Expect request header field after the hook
154 for ap_post_read_request, since that is the only opportunity for
155 modules to handle Expect extensions. [Justin Erenkrantz]
157 *) Rewrite of aaa modules to an authn/authz model.
158 [Dirk-Willem van Gulik, Justin Erenkrantz]
161 [Apache 2.1.0-dev includes those bug fixes and changes with the
162 Apache 2.0.xx tree as documented, and except as noted, below.]
164 Changes with Apache 2.0.46
166 *) Fixed a segfault when multiple ProxyBlock directives were used.
167 PR: 19023 [Sami Tikka <sami.tikka@f-secure.com>]
169 *) SECURITY [CAN-2003-0134] OS2: Fix a Denial of Service vulnerability
170 identified and reported by Robert Howard <rihoward@rawbw.com> that
171 where device names faulted the running OS2 worker process.
172 The fix is actually in APR 0.9.4. [Brian Havard]
174 *) Forward port: Escape special characters (especially control
175 characters) in mod_log_config to make a clear distinction between
176 client-supplied strings (with special characters) and server-side
177 strings. This was already introduced in version 1.3.25.
180 *) mod_deflate: Check also err_headers_out for an already set
181 Content-Encoding: gzip header. This prevents gzip compressed content
182 from a CGI script from being compressed once more. PR 17797.
185 Changes with Apache 2.0.45
187 *) Fix possible segfaults under obscure error conditions within the
188 cgid daemon. [Jeff Trawick, William Rowe]
190 *) SECURITY [CAN-2003-0132]: Close a Denial of Service vulnerability
191 identified by David Endler <DEndler@iDefense.com> on all platforms.
192 An unlimited stream of newlines were acceptable between requests
193 where each <lf> would allocate an 80 byte buffer, leading very
194 quickly to memory exahustion. [Brian Pane]
196 *) Added an rpm build script.
197 [Graham Leggett, Joe Orton <jorton@redhat.com>]
199 *) Simpler, faster code path for request header scanning [Brian Pane]
201 *) SECURITY: Eliminated leaks of several file descriptors to child
202 processes, such as CGI scripts. This fix depends on the APR library
203 release 0.9.2 or later (0.9.3 was distributed with the httpd
204 source tarball for Apache 2.0.45.) PR 17206
205 [Christian Kratzer <ck@cksoft.de>, Bjoern A. Zeeb <bz@zabbadoz.net>]
207 *) Fix path handling of mod_rewrite, especially on non-unix systems.
208 There was some confusion between local paths and URL paths.
209 PR 12902. [André Malo]
211 *) Prevent endless loops of internal redirects in mod_rewrite by
212 aborting after exceeding a limit of internal redirects. The
213 limit defaults to 10 and can be changed using the RewriteOptions
214 directive. PR 17462. [André Malo]
216 *) Win32: Avoid busy wait (consuming all the CPU idle cycles) when
217 all worker threads are busy.
218 [Igor Nazarenko <igor_nazarenko@hotmail.com>]
220 *) Keep the subrequest filter in place when a subrequest is
221 redirected. PR 15423. [Jeff Trawick]
223 *) you can now specify the compression level for mod_deflate.
224 [Ian Holsman, Stephen Pierzchala <stephen@pierzchala.com>,
225 Michael Schroepl <Michael.Schroepl@telekurs.de>]
227 *) mod_deflate: Extend the DeflateFilterNote directive to
228 allow accurate logging of the filter's in- and outstream.
231 *) Allow SSLMutex to select/use the full range of APR locking
232 mechanisms available to it. Also, fix the bug that SSLMutex uses
233 APR_LOCK_DEFAULT no matter what. PR 8122 [Jim Jagielski,
234 martin.t.kutschker@blackbox.net (Martin Kutschker)]
236 *) Restore the ability of htdigest.exe to create files that contain
237 more than one user. PR 12910. [André Malo]
239 *) Improve binary compatibility of the core between debug (aka
240 maintainer-mode) and a non-debug compile.
243 *) mod_usertrack: don't set the cookie in subrequests. This works
244 around the problem that cookies were set twice during fast internal
245 redirects. PR 13211. [André Malo]
247 *) mod_autoindex no longer forgets output format and enabled version
248 sort in linked column headers. [André Malo]
250 *) Use .sv instead of .se as extension for Swedish documents in the
251 default configuration. PR 12877. [André Malo]
253 *) Updated mod_ldap and mod_auth_ldap to support the Novell LDAP SDK SSL
254 and standardized the LDAP SSL support across the various LDAP SDKs.
255 Isolated the SSL functionality to mod_ldap rather than speading it
256 across mod_auth_ldap and mod_ldap. Also added LDAPTrustedCA
257 and LDAPTrustedCAType directives to mod_ldap to allow for a more
258 common method of specifying the SSL certificate.
259 [Dave Ward, Brad Nicholes]
261 *) Fixed mod_ssl's SSLCertificateChain initialization to no longer
262 skip the first cert of the chain by default. This misbehavior
263 was introduced in 2.0.34. PR 14560 [Madhusudan Mathihalli]
265 *) mod_cgi, mod_cgid, mod_ext_filter: Log errors when scripts cannot
266 be started on Unix because of such problems as bad permissions,
267 bad shebang line, etc. [Jeff Trawick]
269 *) Fix 64-bit problem in mod_ssl input logic.
270 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
272 *) Fix potential memory leaks in mod_deflate on malformed data. PR 16046.
275 *) Rewrite ap_xml_parse_input to use bucket brigades. PR 16134.
278 *) Fix segfault which occurred when a section in an included
279 configuration file was not closed. PR 17093. [André Malo]
281 *) Enhance the behavior of mod_isapi's WriteClient() callback to
282 provide better emulation for isapi modules that presume that the
283 first WriteClient() call may send status and headers. An example
284 of WriteClient() abuse is the foxisapi module, which relies on
285 that assumpion and now works. [William Rowe, Milan Kosina]
287 *) Check the return value of ap_run_pre_connection(). So if the
288 pre_connection phase fails (without setting c->aborted)
289 ap_run_process_connection is not executed. [Stas Bekman]
291 *) Fixed a problem with mod_ldap which caused it to fault when caching
292 was disabled. Needed to make sure that the code did not
293 attempt to use the cache if it didn't exist. Also fixed some memory
294 leaks which were due to not releasing LDAP resources on error
295 conditions. [Brad Nicholes]
297 *) Hook mod_proxy's fixup before mod_rewrite's fixup, so that by
298 mod_rewrite proxied URLs will not be escaped accidentally by
299 mod_proxy's fixup. PR 16368 [André Malo]
301 *) While processing filters on internal redirects, remember seen EOS
302 buckets also in the request structure of the redirect issuer(s). This
303 prevents filters (such as mod_deflate) from adding garbage to the
304 response. PR 14451. [André Malo]
306 *) suexec: Be more pedantic when cleaning environment. Clean it
307 immediately after startup. PR 2790, 10449.
308 [Jeff Stewart <jws@purdue.edu>, André Malo]
310 *) Fix apxs to insert LoadModule directives only outside of sections.
311 PR 8712, 9012. [André Malo]
313 *) Fix suexec compile error under SUNOS4, where strerror() doesn't
314 exist. PR 5913, 9977.
315 [Jonathan W Miner <Jonathan.W.Miner@lmco.com>]
317 *) Fix If header parsing when a non-mod_dav lock token is passed to it.
318 PR 16452. [Justin Erenkrantz]
320 *) mod_auth_digest no longer tries to guess AuthDigestDomain, if it's
321 not specified. Now it assumes "/" as already documented. PR 16937.
324 *) Try to log an error if a piped log program fails. Try to
325 restart a piped log program in more failure situations. Fix an
326 existing problem with error handling in piped_log_spawn(). Use
327 new APR apr_proc_create() features to prevent Apache from starting
328 on Unix* in most cases where a piped log program can be started,
329 and add log messages for the other situations. *Other platforms
330 already failed Apache initialization if a piped log program
331 couldn't be started. PR 15761 [Jeff Trawick]
333 *) Fix mod_cern_meta to not create empty metafiles when the
334 metafile searched for does not exist. PR 12353
335 [Owen Rees <owen_rees@hp.com>]
337 *) Introduce debugging symbols for Win32 release builds, both .pdb
338 and .dbg files (older debuggers and Dr. Watson-type utilities
339 on WinNT or Win9x don't support the newer .pdb flavor.)
340 [Allen Edwards, William Rowe]
342 *) Fix bug where 'Satisfy Any' without an AuthType lost all MIME
343 information (and more). Related to PR 9076. [André Malo]
345 *) mod_file_cache: fix segfault serving mmaped cached files.
348 *) mod_file_cache: fixed a segfault when multiple MMapFile directives
349 were used. PR 16313. [Cliff Woolley]
351 *) Fix a nasty segfault in mmap_bucket_setaside() caused by passing
352 an incompatible pointer type to mmap_bucket_destroy(void*).
353 [Gerard Eviston <geviston@bigpond.net.au>]
355 *) Enable the -n name parameter on NetWare to allow the
356 administrator to rename the Apache console screen
359 *) Fixed piped access logs on Win32 by disabling OTHER_CHILD
360 support by default in APR. More development is required
361 to deploy OTHER_CHILD on Win32. [William Rowe]
363 *) Use saner default config values for suexec. PR 15713.
364 [Thom May <thom@planetarytramp.net>]
366 *) mod_rewrite: Allow "RewriteEngine Off" even if no "Options FollowSymlinks"
367 (or SymlinksIfOwnermatch) is set. PR 12395. [André Malo]
369 *) apxs: Include any special APR ld flags when linking the DSO.
370 This resolves problems on AIX when building a DSO with apxs+gcc.
373 *) Added character set support to mod_auth_LDAP to allow it to
374 convert extended characters used in the user ID to UTF-8
375 before authenticating against the LDAP directory. The new
376 directive AuthLDAPCharsetConfig is used to specify the config
377 file that contains the character set conversion table.
380 *) Don't remove the Content-Length from responses in mod_proxy
381 PR: 8677 [Brian Pane]
383 *) Ensure LDAP version is set to v3 on every bind. PR 14235.
384 [Sergey A. Lipnevich <sergeyli@pisem.net>]
386 *) Fix mod_ldap to open an existing shared memory file should one
387 already exist. PR 12757. [Scooter Morris <scooter@gene.com>,
390 *) Fix the ulimit command used by apachectl on Tru64. PR 13609.
391 [Joseph Senulis <Joseph.Senulis@dnr.state.wi.us>, Jeff Trawick]
393 *) Change the ulimit command used by apachectl on AIX so that it
394 works in all locales. [Jeff Trawick]
396 *) mod_ext_filter: Fix a problem building argument lists which
397 occasionally caused exec to fail. PR 15491. [Jeff Trawick]
399 Changes with Apache 2.0.44
401 *) mod_autoindex: Bring forward the IndexOptions IgnoreCase option
402 from Apache 1.3. PR 14276
403 [David Shane Holden <dpejesh@yahoo.com>, William Rowe]
405 *) mod_mime: Workaround to prevent a segfault if r->filename=NULL
408 *) Reorder the definitions for mod_ldap and mod_auth_ldap within
409 config.m4 to make sure the parent mod_ldap is defined first.
410 This ensures that mod_ldap comes before mod_auth_ldap in the
411 httpd.conf file, which is necessary for mod_auth_ldap to load.
412 PR 14256 [Graham Leggett]
414 *) Fix the building of cgi command lines when the query string
415 contains '='. PR 13914 [Ville Skyttä <ville.skytta@iki.fi>,
418 *) Rename CacheMaxStreamingBuffer to MCacheMaxStreamingBuffer. Move
419 implementation of MCacheMaxStreamingBuffer from mod_cache to
420 mod_mem_cache. MCacheMaxStreamingBuffer now defaults to the
421 lesser of 100,000 bytes or MCacheMaxCacheObjectSize. This should
422 eliminate the need for explicitly coding MCacheMaxStreamingBuffer
423 in most configurations. [Bill Stoddard]
425 *) mod_cache: Fix PR 15113, a core dump in cache_in_filter when
426 a redirect occurs. The code was passing a format string and
427 integer to apr_pstrcat. Changed to apr_psprintf.
430 *) Replace APU_HAS_LDAPSSL_CLIENT_INIT with APU_HAS_LDAP_NETSCAPE_SSL
431 as set by apr-util in util_ldap.c. This should allow mod_ldap
432 to work with the Netscape/Mozilla LDAP library. [Øyvin Sømme
433 <somme@oslo.westerngeco.slb.com>, Graham Leggett]
435 *) Fix critical bug in new --enable-v4-mapped configure option
436 implementation which broke IPv4 listening sockets on some
437 systems. [hiroyuki hanai <hanai@imgsrc.co.jp>]
439 *) mod_setenvif: Fix BrowserMatchNoCase support for non-regex
440 patterns [André Malo <nd@perlig.de>]
442 *) Add version string to provider API. [Justin Erenkrantz]
444 *) build: './configure && make' now works without an in-tree
445 apr and apr-util. [Wilfredo Sanchez]
447 *) mod_negotiation: Set the appropriate mime response headers
448 (Content-Type, charset, Content-Language and Content-Encoding)
449 for negotated type-map "Body:" responses (such as the error
450 pages.) [André Malo <nd@perlig.de>]
452 *) mod_log_config: Allow '%%' escaping in CustomLog format
453 strings to insert a literal, single '%'.
454 [André Malo <nd@perlig.de>]
456 *) mod_autoindex: AddDescription directives for directories
457 now work as in Apache 1.3, where no trailing '/' is
458 specified on the directory name. Previously, the trailing
459 '/' *had* to be specified, which was incompatible with
460 Apache 1.3. PR 7990 [Jeff Trawick]
462 *) Fix for PR 14556. The expiry calculations in mod_cache were
463 trying to perform "now + ((date - lastmod) * factor)" where
464 date == lastmod resulting in "now + 0". The code now follows
465 the else path (using the default expiration) if date is
466 equal to lastmod. [rx@armstrike.com (Sergey), Paul J. Reder]
468 *) Use AP_DECLARE in the debug versions of ap_strXXX in case the
469 default calling convention is not the same as the one used by
470 AP_DECLARE. [Juan Rivera <Juan.Rivera@citrix.com>]
472 *) mod_cache: Don't cache response header fields designated
473 as hop-by-hop headers in HTTP/1.1 (RFC 2616 Section 13.5.1).
474 [Estrade Matthieu <estrade-m@ifrance.com>, Brian Pane]
476 *) mod_cgid: Handle environment variables containing newlines.
477 PR 14550 [Piotr Czejkowski <apache@czarny.eu.org>, Jeff
480 *) Move mod_ext_filter out of experimental and into filters.
483 *) Fixed a memory leak in mod_deflate with dynamic content.
484 PR 14321 [Ken Franken <kfranken@decisionmark.com>]
486 *) Add --[enable|disable]-v4-mapped configure option to control
487 whether or not Apache expects to handle IPv4 connections
488 on IPv6 listening sockets. Either setting will work on
489 systems with the IPV6_V6ONLY socket option. --enable-v4-mapped
490 must be used on systems that always allow IPv4 connections on
491 IPv6 listening sockets. PR 14037 (Bugzilla), PR 7492 (Gnats)
494 *) This fixes a problem where the underlying cache code
495 indicated that there was one more element on the cache
496 than there actually was. This happened since element 0
497 exists but is not used. This code allocates the correct
498 number of useable elements and reports the number of
499 actually used elements. The previous code only allowed
500 MCacheMaxObjectCount-1 objects to be stored in the
501 cache. [Paul J. Reder]
503 *) mod_setenvif: Add SERVER_ADDR special keyword to allow
504 envariable setting according to the server IP address
505 which received the request. [Ken Coar]
507 *) mod_cgid: Terminate CGI scripts when the client connection
508 drops. PR 8388 [Jeff Trawick]
510 *) Rearrange OpenSSL engine initialization to support RAND
511 redirection on crypto accelerator.
512 [Frederic DONNAT <frederic.donnat@zencod.com>]
514 *) Always emit Vary header if mod_deflate is involved in the
515 request. [Andre Malo <nd@perlig.de>]
517 *) mod_isapi: Stop unsetting the 'empty' query string result with
518 a NULL argument in ecb->lpszQueryString, eliminating segfaults
519 for some ISAPI modules. PR 14399
520 [Detlev Vendt <detlev.vendt@brillit.de>]
522 *) mod_isapi: Fix an issue where the HSE_REQ_DONE_WITH_SESSION
523 notification is received before the HttpExtensionProc() returns
524 HSE_STATUS_PENDING. This only affected isapi .dll's configured
525 with the ISAPIFakeAsync on directive. PR 11918
526 [John DeSetto <jdesetto@radiantsystems.com>, William Rowe]
528 *) mod_isapi: Fix the issue where all results from mod_isapi would
529 run through the core die handler resulting in invalid responses
530 or access log entries. PR 10216 [William Rowe]
532 *) Improves the user friendliness of the CacheRoot processing
533 over my last pass. This version avoids the pool allocations
534 but doesn't avoid all of the runtime checks. It no longer
535 terminates during post-config processing. An error is logged
536 once per worker, indicating that the CacheRoot needs to be set.
539 *) Fix a bug where we keep files open until the end of a
540 keepalive connection, which can result in:
541 (24)Too many open files: file permissions deny server access
542 especially on threaded servers. [Greg Ames, Jeff Trawick]
544 *) Fix a bug in which mod_proxy sent an invalid Content-Length
545 when a proxied URL was invoked as a server-side include within
546 a page generated in response to a form POST. [Brian Pane]
548 *) Added code to process min and max file size directives and to
549 init the expirychk flag in mod_disk_cache. Added a clarifying
550 comment to cache_util. [Paul J. Reder]
552 *) The value emitted by ServerSignature now mimics the Server HTTP
553 header as controlled by ServerTokens. [Francis Daly <deva@daoine.org>]
555 *) Gracefully handly retry situations in the SSL input filter,
556 by following the SSL libraries' retry semantics.
559 *) Terminate CGI scripts when the client connection drops. This
560 fix only applies to some normal paths in mod_cgi. mod_cgid
561 is still busted. PR 8388 [Jeff Trawick]
563 *) Fix a bug where 416 "Range not satisfiable" was being
564 returned for content that should have been redirected.
567 *) Fix memory leak in mod_ssl from internal SSL library allocations
568 within SSL_get_peer_certificate and X509_get_pubkey.
569 [Zvi Har'El <rl@math.technion.ac.il>
570 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>].
572 *) mod_ssl uses free() inappropriately in several places, to free
573 memory which has been previously allocated inside OpenSSL.
574 Such memory should be freed with OPENSSL_free(), not with free().

590 [Jonas Eriksson <jonas@webkonsulterna.com>]
592 *) Change the CacheRoot processing to check for a required
593 value at config time. This saves a lot of wasted processing
594 if the mod_disk_cache module is loaded but no CacheRoot
595 was provided. This fix also adds code to log an error
596 and avoid useless pallocs and procesing when the computed
597 cache file name cannot be opened. This also updates the
598 docs accordingly. [Paul J. Reder]
600 *) Introduce the EnableSendfile directive, allowing users of NFS
601 shares to disable sendfile mechanics when they either fail
602 outright or provide intermitantly corrupted data. PR

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

636 Changes with Apache 2.0.43
638 *) SECURITY: [CAN-2002-0840] HTML-escape the address produced by
639 ap_server_signature() against this cross-site scripting
640 vulnerability exposed by the directive 'UseCanonicalName Off'.
641 Also HTML-escape the SERVER_NAME environment variable for CGI
642 and SSI requests. It's safe to escape as only the '<', '>',
643 and '&' characters are affected, which won't appear in a valid
644 hostname. Reported by Matthew Murphy <mattmurphy@kc.rr.com>.
647 *) Fix a core dump in mod_cache when it attemtped to store uncopyable
648 buckets. This happened, for instance, when a file to be cached
649 contained SSI tags to execute a CGI script (passed as a pipe
650 bucket). [Paul J. Reder]
652 *) Ensure that output already available is flushed to the network
653 when the content-length filter realizes that no new output will
654 be available for a while. This helps some streaming CGIs as

765 *) The content-length filter no longer tries to buffer up
766 the entire output of a long-running request before sending
767 anything to the client. [Brian Pane]
769 *) Win32: Lower the default stack size from 1MB to 256K. This will
770 allow around 8000 threads to be started per child process.
771 'EDITBIN /STACK:size apache.exe' can be used to change this

822 *) mod_disk_cache works much better. This module should still
823 be considered experimental. [Eric Prud'hommeaux]
825 *) Performance improvement for keepalive requests: when setting
826 aside a small file for potential concatenation with the next
827 response on the connection, set aside the file descriptor rather
828 than copying the file into the heap. [Brian Pane]
830 *) Modified version check on openssl so that it finds the executable
831 first and then performs a check of the version, only warning the
832 user if they chose, or we selected, an old version of OpenSSL.
833 This change also allows the code to work for non-openssl libraries
834 selected via the --with-ssl=dir option, which can override the
835 automated library check in any case. [Roy Fielding]
837 Changes with Apache 2.0.40
839 *) SECURITY: [CAN-2002-0661] Close a very significant security hole that
840 applies only to the Win32, OS2 and Netware platforms. Unix was not
841 affected, Cygwin may be affected. Certain URIs will bypass security
842 and allow users to invoke or access any file depending on the system
843 configuration. Without upgrading, a single .conf change will close
844 the vulnerability. Add the following directive in the global server
845 httpd.conf context before any other Alias or Redirect directives;
846 RedirectMatch 400 "\\\.\."
847 Reported by Auriemma Luigi <bugtest@sitoverde.com>.
850 *) SECURITY: Close a path-revealing exposure in multiview type
851 map negotiation (such as the default error documents) where the
852 module would report the full path of the typemapped .var file when
853 multiple documents or no documents could be served based on the mime
854 negotiation. Reported by Auriemma Luigi <bugtest@sitoverde.com>.
855 [CAN-2002-0654] [William Rowe]
857 *) SECURITY: Close a path-revealing exposure in cgi/cgid when we
858 fail to invoke a script. The modules would report "couldn't create
859 child process /path-to-script/script.pl" revealing the full path
860 of the script. Reported by Jim Race <jrace@qualys.com>.
861 [CAN-2002-0654] [Bill Stoddard]
863 *) Set aside the apr-iconv and apr_xlate() features for the Win32
864 build of 2.0.40 so development can be completed. A patch, from
865 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
866 will be available for those that wish to work with apr-iconv.
869 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
870 chain. [Peter Van Biesen <peter.vanbiesen@vlafo.be>]
872 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
873 set to 1, so we can exclude things from the general case with
874 browsermatch. [Ian Holsman, Andre Schild <A.Schild@aarboard.ch>]
876 *) Accept multiple leading /'s for requests within the DocumentRoot.
877 PR 10946 [William Rowe, David Shane Holden <dpejesh@yahoo.com>]
879 *) Solved the reports of .pdf byterange failures on Win32 alone.
880 APR's sendfile for the win32 platform collapses header and trailer
881 buffers into a single buffer. However, we destroyed the pointers
882 to the header buffer if a trailer buffer was present. PR 10781
885 *) mod_ext_filter: Add the ability to enable or disable a filter via
886 an environment variable. Add the ability to register a filter of
887 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
889 *) Restore the ability to specify host names on Listen directives.
890 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh@yahoo.com>]
892 *) When deciding on the default address family for listening sockets,
893 make sure we can actually bind to an AF_INET6 socket before
894 deciding that we should default to AF_INET6. This fixes a startup
895 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
897 *) Replace usage of atol() to parse strings when we might want a
898 larger-than-long value with apr_atoll(), which returns long long.
899 This allows HTTPD to deal with larger files correctly.
900 [Shantonu Sen <ssen@apple.com>]
902 *) mod_ext_filter: Ignore any content-type parameters when checking if
903 the response should be filtered. Previously, "intype=text/html"
904 wouldn't match something like "text/html;charset=8859_1".
907 *) mod_ext_filter: Set up environment variables for external programs.
908 [Craig Sebenik <craig@netapp.com>]
910 *) Modified the HTTP_IN filter to immediately append the EOS (end of
911 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
912 the caller to determine that no content remains without prefetching
913 additional POST body. [William Rowe]

938 *) APR-Util Renames pending have been completed [Thom May]
940 *) Performance improvements for the code that reads request
941 headers (ap_rgetline_core() and related functions) [Brian Pane]
943 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
944 to configure the maximum amount of memory the allocators will
945 hold on to for reuse. Anything over the MaxMemFree threshold
946 will be free()d. This directive is useful when uncommon large
947 peaks occur in memory usage. It should _not_ be used to mask
948 defective modules' memory use. [Sander Striker]
950 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
951 scripts would not result in a truncated response.
952 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
954 *) Add a filter_init parameter to the filter registration functions
955 so that a filter can execute arbitrary code before the handlers
956 are invoked. This resolves a problem where mod_include requests
957 would incorrectly return a 304. [Justin Erenkrantz]
959 *) Fix a long-standing bug in 2.0, CGI scripts were being called
960 with relative paths instead of absolute paths. Apache 1.3 used
961 absolute paths for everything except for SuExec, this brings back
962 that standard. [Ryan Bloom]
964 *) Fix infinite loop due to two HTTP_IN filters being present for
965 internally redirected requests. PR 10146. [Justin Erenkrantz]
967 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
970 *) Fix mod_ext_filter to look in the main server for filter definitions
971 when running in a vhost if the filter definition is not found in
972 the vhost. PR 10147 [Jeff Trawick]
974 *) Support WinNT CGI invocation through ScriptInterpreterSource
975 'registry' for script interpreter paths and names with non-ascii
976 characters in the executable filepath. [William Rowe]
978 *) Support the -w flag on to keep the Win32 console open on error.
981 *) Normalize the hostname value in the request_rec to all-lowercase
982 [Perry Harrington <pedward@webcom.com>]
984 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
985 extended characters (non US-ASCII) in non-utf8 format. This brings
986 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
987 to the cgi application itself. [William Rowe]
989 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
990 modules to bring them up to the current apr/apr-util APIs.
993 *) Fix segfault in mod_mem_cache most frequently observed when
994 serving the same file to multiple clients on an MP machine.
997 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
998 [Brian Degenhardt <bmd@mp3.com>, Ian Holsman]
1000 *) Fix perchild to work with apachectl by adding -k support to perchild.
1001 PR 10074 [Jeff Trawick]
1003 *) Fix a silly htpasswd.c logic error that incorrectly reported that
1004 both -c and -n had been used. PR 9989 [Cliff Woolley]
1006 *) Fixed a mod_include error case in which no HTTP response was sent
1007 to the client if an shtml document contained an unterminated SSI
1008 directive [Brian Pane]
1010 *) Improve ap_get_client_block implementation by using APR-util brigade
1011 helper functions and relying on current filter assumptions.
1014 Changes with Apache 2.0.39
1016 *) Fixed a build problem in htpasswd.c on Win32.
1017 [Guenter Knauf <eflash@gmx.net>, Cliff Woolley]
1019 Changes with Apache 2.0.38
1021 *) Rewrite htpasswd to use APR. The removes the annoying warning about
1022 tmpnam being unsafe. [Ryan Bloom]
1024 *) We must set the MIME-type for .shtml files to text/html if we want them
1025 to be parsed for SSI tags. Add the config for that to the default
1026 config file so that it is easier to enable .shtml parsing.
1027 [Dave Dyer <ddyer@real-me.net>]
1029 *) Fixed a problem with 'make install' on ReliantUnix.
1030 [Jean-frederic Clere <jfrederic.clere@fujitsu-siemens.com>]
1032 *) Make the default_handler catch all requests that aren't served by
1033 another handler. This also gets us to return a 404 if a directory
1034 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1035 loaded. [Justin Erenkrantz]
1037 *) Fixed the handling of nested if-statements in shtml files.
1038 PR 9866 [Brian Pane]
1040 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1041 into a directory different from the one that was configured. This
1042 also mirrors the root= feature from 1.3. We cannot use prefix=,
1043 because both APR and APR-util resolve their installation paths at
1044 configuration time. This means that there is no variable prefix
1045 to replace. [Andreas Hasenack <andreas@netbank.com.br>]
1047 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1048 These levels of AIX don't have a thundering herd problem with
1049 accept(). [Jeff Trawick]
1051 *) prefork MPM: Ignore mutex errors during graceful restart. For
1052 certain types of mutexes (particularly SysV semaphores), we
1053 should expect to occasionally fail to obtain or release the
1054 mutex during restart processing. [Jeff Trawick]
1056 *) Fix install-bindist.sh so that it finds any perl instead of just
1057 early perl 5.x versions. This is consistent with a build/install
1058 from source, and it allows the perl scripts installed by a bindist
1059 to work on systems with perl 5.6. [Jeff Trawick]
1061 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
1062 Tru64 (and probably some other platforms). [Jeff Trawick]
1064 *) Allow CGI scripts to return their Content-Length. This also fixes a
1065 hang on HEAD requests seen on certain platforms (such as FreeBSD).

1421 explicitly tell the server that warning messages should be sent
1422 to the client in addition to being recorded in the error log.
1423 Prior to this change, ap_log_rerror() always sent warning
1424 messages to the client. In one case, a faulty CGI script caused
1425 the server to send a warning message to the client that contained
1426 the full path to the CGI script. This could be considered a
1427 minor security exposure. [Bill Stoddard]

1443 *) Change instdso.sh to use libtool --install everywhere and then
1444 clean up some stray files and symlinks that libtool leaves around
1445 on some platforms. This gets subversion building properly since
1446 it needed a re-link to be performed by libtool at install time,

1460 cache entry. [Bill Stoddard]
1462 *) Introduced -E startup_logfile_name option to httpd to allow admins
1463 to begin logging errors immediately. This provides Win32 users
1464 an alternative to sending startup errors to the event viewer, and

1554 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
1555 cause the Apache parent process to run in the foreground (similar to
1556 -DNO_DETACH except that it doesn't switch session ids).
1559 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
1560 for those platforms that support it. If using the default
1561 implementation, this is between pthread and sysvsem in priority.

1650 *) Added exp_foo and rel_foo variables to config_vars.mk for
1651 all Apache and Autoconf path variables (like --sysconfdir,
1652 --sbindir, etc). exp_foo is the "expanded" version, which means
1653 that all internal variable references have been interpolated.

1714 directory to the build directory. PR 10163 [Jeff Trawick]
1716 *) Fix some mod_include problems which broke evaluation of some
1717 expressions. PR 10108 [Jeff Trawick]
1719 *) Fix the calculation of request time in mod_status. [Stas Bekman]
1721 *) Fix the calculation of thread_num in the worker score structure.
1724 *) Use apr_atomic operations in managing the mod_mem_cache
1725 cache_objects for SMP scalability. (see USE_ATOMICS
1726 preprocessor directive in mod_file_cache)
1729 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
1730 preprocessor directive in mod_file_cache)
1733 *) Implement prototype mod_disk_cache for use with mod_cache.
1736 *) Add a missing manualdir entry in the Debian config.layout.
1737 [Thom May <thom@planetarytramp.net>]
1739 *) Stop installing libtool for APR and tell APR where it should place
1740 its copy of libtool (via our installbuildpath layout variable).
1743 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
1744 when reading from a remote HTTP server in proxy. [Graham Leggett]
1746 *) Modify receive/send loop in proxy_http and proxy_ftp so that
1747 should it be necessary, the remote server socket is closed before
1748 transmitting the last buffer (set by ProxyIOBufferSize) to the
1749 client. This prevents the backend server from being forced to hang
1750 around while the last few bytes are transmitted to a slow client.
1751 Fix the case where no error checking was performed on the final
1752 brigade in the loop. [Graham Leggett]
1754 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
1755 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
1756 hours. [Graham Leggett, Bill Stoddard]
1758 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
1759 for a undefined variable. [Ian Holsman]
1761 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
1762 when we can't get a socket in the specified address family. We may
1763 have gotten back an IPv6 address first and yet our system is not
1764 configured to allow IPv6 sockets. [Jeff Trawick]
1766 *) Be more careful about recursively removing CVS directories. Make
1767 sure that we aren't cd'ing to their home directory first. PR: 9993
1768 [Aaron Bannert, James LewisMoss <dres@lewismoss.net>]
1770 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
1771 [Dirk-Jan Faber <dirk-jan@selwerd.nl>, Aaron Bannert,
1772 Thom May <thom@planetarytramp.net>]
1774 *) Rename the filter ordering priorities. The recent filtering fixes
1775 have showcased problems with their usage. Therefore, we need to
1776 rename them to increase the clarity. (CONTENT->RESOURCE,
1777 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
1779 Changes with Apache 2.0.33
1781 *) Fix a problem in the new --enable-layout functionality where
1782 it wouldn't allow overrides from variables like --prefix,
1783 --bindir, etc. [Thom May <thom@planetarytramp.net>]
1785 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
1786 no longer hangs around waiting for the socket to close before
1787 returning exhaustive data. [Aaron Bannert]
1789 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
1790 [Thom May <thom@planetarytramp.net>]
1792 *) Change mod_ssl to always do a full startup/teardown on restarts.
1793 this allows mod_ssl to be added to a server that is already
1794 running and makes it possible to add/change certs/keys after the
1795 server has been started. [Doug MacEachern]
1797 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
1798 This pipe must be a bidirectional 'console' style relay, which
1799 mod_ssl prints all prompts to the pipe's stdin, and reads the
1800 passphrases from the pipe's stdout. [William Rowe]
1802 *) Fix bug where --sysconfdir and --localstatedir were being
1803 ignored. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
1806 *) Fix --enable-layout to work again. Caution: When specifying
1807 --enable-layout, common arguments like --prefix, --exec-prefix,
1808 etc. will be ignored and the settings from the layout will be
1809 used instead. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
1812 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
1813 regex pattern matching for the determination of which requests
1814 to use the remote proxy for. [Jim Jagielski]
1816 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
1818 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
1819 cruft in piped logs and rewritemap child processes.
1822 *) All instances of apr_lock_t have been removed and converted
1823 to one of the following new lock APIs: apr_thread_mutex.h,
1824 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
1825 use the apr_lock.h API, as the old API will soon be deprecated.
1828 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
1829 [Ralf S. Engelschall, Cliff Woolley]
1831 *) mod-include: make it handle flush'es and fix the 'false-alarm'
1832 [Justin Erenkrantz, Brian Pane, Ian Holsman]
1834 *) ap_get_*_filter_handle() functions to allow 3rd party modules
1835 to lookup filter handles so they can bypass the filter name
1836 lookup when adding filters to a request (via ap_add_*_filter_handle())
1837 [Ryan Morgan <rmorgan@covalent.net>]
1839 *) Fix for multiple file buckets on Win32, where the first file
1840 bucket would cause the immediate closure of the socket on any
1841 non-keepalive requests. [Ryan Morgan <rmorgan@covalent.net>]
1843 *) Correct Win32 failure of mmap of a segment beyond start of the
1844 file; fixes large SSL and similar transfers. [William Rowe]
1847 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
1848 multi-process mode to not "daemonize" while detaching from the
1849 controlling terminal. This is necessary for Apache to work with
1850 process-management tools like AIX's "System Resource Controller"
1851 as well as Dan Bernstein's "daemontools".
1852 [Jos Backus <josb@cncdsl.com>, Aaron Bannert]
1854 *) Convert mod_auth_digest to use the new apr_global_mutex_t
1855 type. [Aaron Bannert]
1857 *) fix bug in mod-include where it wouldn't send a unmatched
1858 part if it was at the end of a bucket [Ian Holsman]
1860 *) worker MPM: Improve logging of errors with the interface between
1861 the listener thread and worker threads. [Jeff Trawick]
1863 *) Some browsers ignore cookies that have been merged into a
1864 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
1865 are now unmerged in the http proxy before being sent to the
1866 client. [Graham Leggett]
1868 *) Fix a problem with proxy where each entry of a duplicated
1869 header such as Set-Cookie would overwrite and obliterate the
1870 previous value of the header, resulting in multiple header
1871 values (like cookies) going missing.
1872 [Graham Leggett, Joshua Slive]
1874 *) Add the server-limit and thread-limit values to the scoreboard
1875 for the sake of third-party applications.
1876 [Adam Sussman <myddryn@vishnu.vidya.com>]
1878 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
1880 *) OS/390: Get make install to properly copy DSO modules.
1883 *) Win32: Fix bug in mod_status with displaying "Restart Time"
1884 and "Server uptime".
1887 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
1889 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
1891 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
1892 [David MacKenzie <djm@pix.net>]
1894 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
1895 [David MacKenzie <djm@pix.net>]
1897 *) Fix segfault and display error when SSLMutex file can not be
1898 created. [Adam Sussman <myddryn@vishnu.vidya.com>]
1900 *) Add reference counting to mod_mem_cache cache objects to
1901 better manage removing objects from the cache.
1904 *) Change the verbage on the ScoreBoardFile in our default configs.
1905 Also change the default to be commented out (unspecified) so we
1906 get anonymous shared memory by default. [Aaron Bannert]
1908 *) Implement new ScoreBoardFile directive logic. This affects how
1909 we create the scoreboard's shared memory segment. If the directive
1910 is present, a name-based segment is created. If the directive is
1911 not present, first an anonymous segment is created, and if that
1912 fails, a name-based segment is created from a file of the name
1913 DEFAULT_SCOREBOARD. This gives third-party applications the
1914 ability to access our scoreboard. [Aaron Bannert]
1916 *) Allow mod_deflate to work with non-GET requests and properly send
1917 Content-Lengths. [Sander Striker <striker@apache.org>]
1919 *) Fix ap_directory_merge() to correctly merge configs when there is
1920 no <Directory /> block. [Justin Erenkrantz, William Rowe]
1922 *) Remove spurious debug messsages that are normal under HTTP
1923 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
1925 *) Fix a bug in mod_cgid that would prevent proper shutdown death
1926 of the cgid process. [Aaron Bannert]
1928 *) Add signal handling back in to the worker MPM for the one_process
1929 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
1931 *) Performance: Reuse per-connection transaction pools in the
1932 worker MPM, rather than destroying and recreating them. [Brian Pane]
1934 *) Remove all signals from the worker MPM's child process. Instead,
1935 the parent uses the Pipe of Death for all communication with the
1936 child processes. [Ryan Bloom]
1938 Changes with Apache 2.0.32
1940 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
1941 default if the directive is not specified. This mirrors older
1942 behavior without changes to the httpd.conf. [William Rowe]
1944 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
1945 the service, mpm and logging code, and bugs in apr_file_open_stderr
1946 and apr_file_dup2 functions. Win2K/XP services have no handles
1947 associated for stdin/out/err, which caused unpredictable behavior
1948 in the prior release. [William Rowe, Bill Stoddard]
1950 *) Win32: simplify the Application Event Log messages, since there isn't
1951 likely to be 'more information in the error log' before an error log
1952 has been opened. [William Rowe]
1954 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
1955 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
1957 *) Win32: apache -k shutdown now behaves like apache -k stop.
1960 *) Fix prefork to not kill the parent if a child hits a resource shortage
1961 on accept(). [Greg Ames]
1963 *) Fix seg faults that occur when what should be the httpd request line
1964 starts with \r\n followed by garbage. [Greg Ames]
1966 *) Allow statically linked support binaries with the new
1967 --enable-static-support flag, and enable this behavior in
1968 the binbuild script. Also add a new --enable-static-htdbm
1969 flag. [Aaron Bannert]
1971 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
1972 do only one stat() call when generating the directory listings.
1975 *) Fix resolve_symlink to save the original symlink name if known.
1978 *) Be a bit more sane with regard to CanonicalNames. If the user has
1979 specified they want to use the CanonicalName, but they have not
1980 configured a port with the ServerName, then use the same port that
1981 the original request used. [Ryan Bloom and Ken Coar]
1983 *) In core_input_filter, check for an empty brigade after
1984 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
1985 client says it will post some data but we get FIN before any
1986 data arrives. [Jeff Trawick]
1988 *) Not being able to bind to the socket is a fatal error. We should
1989 print an error to the console, and return a non-zero status code.
1990 With these changes, all of the Unix MPMs do that correctly.
1993 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
1994 through to CGI scripts. PR 9163
1995 [Brian Reid <breid@customlogic.com>,
1996 Zvi Har'El <rl@math.technion.ac.il>]
1998 *) binbuild.sh: Make sure that we use the expat from our source
1999 tree so that there aren't any surprises on the target machine.
2002 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2003 enough to keep up with new requests. Start using
2004 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2005 when we can't talk to the daemon. [Jeff Trawick]
2007 *) apxs: LTFLAGS envvar can override default libtool options. Try
2008 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2009 the covers. [Jeff Trawick]
2011 *) The Location: response header field, used for external
2012 redirect, *must* be an absoluteURI. The Redirect directive
2013 tested for that, but RedirectMatch didn't -- it would allow
2014 almost anything through. Now it will try to turn an abs_path
2015 into an absoluteURI, but it will correctly varf like Redirect
2016 if the final redirection target isn't an absoluteURI. [Ken Coar]
2018 Changes with Apache 2.0.31
2020 *) Create the scoreboard (in the parent) in a global pool context,
2021 so it survives graceful restarts. This fixes a SEGV during
2022 graceful restarts. [Aaron Bannert]
2024 *) Add a timeout option to the proxy code 'ProxyTimeout'
2027 *) FTP directory listings are now always retrieved in ASCII mode.
2028 The FTP proxy properly escapes URI's and HTML in the generated
2029 listing, and escapes the path components when talking to the FTP
2030 server. It is now possible to browse the root directory by using
2031 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2032 Also, the last path component may contain wildcard characters
2033 '*' and '?', and if they do, a directory listing is created instead
2034 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2037 *) Added single-listener unserialized accept support to the
2038 worker MPM [Brian Pane]
2040 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2041 the incoming host header through to the proxied server
2042 [Geoff <g.russell@ieee.org>]
2044 *) New Directive Option for ProxyPass. It now can block a location
2045 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
2047 *) Don't let the default handler try to serve a raw directory. At
2048 best you get gibberish. Much worse things can happen depending
2049 on the OS. [Jeff Trawick]
2051 *) Change the pre_config hook to return a value. Modules can now emit
2052 an error message and then cause the server to quit gracefully during
2053 startup. This required a bump to the MMN. [Aaron Bannert]
2055 *) Fix some unix socket descriptor leaks in the handler side of
2056 mod_cgid (the part that runs in the server process). Whack a
2057 silly "close(-1)" in the handler too. [Jeff Trawick]
2059 *) Change the pre_mpm hook to return a value, so that scoreboard
2060 init errors percolate up to code that knows how to exit
2061 cleanly. This required a bump to the MMN. [Jeff Trawick]
2063 *) Add the socket back to the conn_rec and remove the create_connection
2064 hook. The create_connection hook had a design flaw that did not
2065 allow creating connections based on vhost info. [Bill Stoddard]
2067 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2068 Resolves the common case of using negotation to resolve the request
2069 /script/foo for /script.cgi/foo. [William Rowe]
2071 *) Added new functions ap_add_(input|output)_filter_handle to
2072 allow modules to bypass the usual filter name lookup when
2073 adding hard-coded filters to a request [Brian Pane]
2075 *) caching should now work on subrequests (still very experimental)
2078 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2080 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2083 *) Refactor ap_rgetline so that it does not use an internal brigade.
2084 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2086 *) Remove mod_auth_db. [Justin Erenkrantz]
2088 *) Do not install unnecessary pcre headers like config.h and internal.h.
2089 [Joe Orton <joe@manyfish.co.uk>]
2091 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
2092 (as it does for a normal request). quick_handled sub-requests now work
2093 in mod-include [Ian Holsman]
2095 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
2096 'CONTENT' one, as it needs to run AFTER all content headers
2098 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
2101 *) Split out blocking from the mode in the input filters.
2104 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
2106 *) Cause Win32 to capture all child-worker process errors in
2107 Apache to the main server error log, until the child can
2108 open its own error logs. [William Rowe]
2110 *) HPUX 11.*: Do not kill the child process when accept()
2111 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
2112 by [madhusudan_mathihalli@hp.com])
2115 *) Fix a problem in the parsing of the <Proxy foo> directive.
2118 *) rewrite of mod_ssl input filter for better performance and less
2119 memory usage [Doug MacEachern]
2121 *) allow quick_handler to be run on subrequests. [Ian Holsman]
2123 *) mod_dav now asks its provider to place content directly into the
2124 filter stack when handling a GET request. The mod_dav/provider
2125 API has changed, so providers need to be updated. [Greg Stein]
2127 *) Clear the output socket descriptor in unixd_accept() to make sure
2128 we don't supply a bogus socket to the caller if the accept fails.
2129 This caused problems with the worker MPM, which tried to process
2130 the returned socket if it was non-NULL. [Brian Pane]
2132 *) Move a check for an empty brigade to the start of core input filter
2133 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
2135 *) Add FileETag directive to allow configurable control of what
2136 data are used to form ETag values for file-based URIs. MMN
2137 bumped to 20020111 because of fields added to the end of
2138 the core_dir_config structure. [Ken Coar]
2140 *) Fix a segfault in mod_rewrite's logging code caused by passing the
2141 wrong config to ap_get_remote_host(). [Jeff Trawick]
2143 *) Allow mod_cgid to work from a binary distribution install by
2144 using 755 for the permissions on the log directory instead of
2147 *) Fixed a segfault that happened during graceful shutdown (or when
2148 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
2150 *) Split all Win32 modules [excluding the core components mod_core,
2151 mod_so, mod_win32 and the winnt mpm] into individual loadable
2152 modules, so the administrator may individually disable the former
2153 compiled-in modules by simply commenting out their LoadModule
2154 directives. [William Rowe]
2156 *) Saved Win32 module authors and porters many future headaches, by
2157 duplicating the appropriate .h files such as os.h into the include
2158 directory, including in the build tree. [William Rowe]
2160 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
2161 Use SSL functions/macros instead of directly dereferencing SSL
2162 structures wherever possible.
2163 Add type-casts for the cases where functions return a generic pointer.
2164 Add $SSL/include to configure search path.
2165 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2167 *) Moved several pointers out of the shared Scoreboard so it is
2168 more portable, and will present the vhost name across server
2169 generation restarts. [William Rowe]
2171 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
2174 Changes with Apache 2.0.30
2176 *) Fix the main bug for FreeBSD and threaded MPM's. There are
2177 still issues (see STATUS) but at least the server will now
2178 run without crashing the machine.
2179 [David Reid, Aaron Bannert, Justin Erenkrantz]
2181 *) Fix a typo in mod_deflate's m4 config section.
2182 [albert chin (china@thewrittenword.com)]
2184 *) Fix a couple of mod_proxy problems forwarding HTTP connections
2185 and handling CONNECT:
2186 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
2187 (2) Proxy failed to connect when the first IP address returned by
2188 the resolver was unreachable but a secondary IP address was.
2191 *) Fix the module identifer as shown in the docs for various core
2192 modules (e.g., the identifer for mod_log_config was previously
2193 listed as config_log_module). PR #9338
2194 [James Watson <ap2bug@sowega.org>]
2196 *) Fix LimitRequestBody directive by placing it in the HTTP
2197 filter. [Justin Erenkrantz]
2199 *) Fix mod_proxy seg fault when the proxied server returns
2200 an HTTP/0.9 response or a bogus status line.
2203 *) Prevent mod_proxy from truncating one character off the
2204 end of the status line returned from the proxied server.
2205 [Adam Sussman, Bill Stoddard]
2207 *) Eliminate loop in ap_proxy_string_read().
2208 [Adam Sussman, Bill Stoddard]
2210 *) Provide $0..$9 results from mod_include regex parsing.
2213 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
2215 *) Introduced the ForceLanguagePriority directive, to prevent
2216 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
2217 when using Multiviews. [William Rowe]
2219 *) Fix a problem which prevented mod_cgid and suexec from working
2220 together reliably [Greg Ames]
2222 *) Remove the call to exit() from within mod_auth_digest's post_config
2223 phase. [Aaron Bannert]
2225 *) Fix a problem in mod_auth_digest that could potentially cause
2226 problems with initialized static data on a system that uses DSOs.
2229 *) Fix a segfault in the worker MPM that could happen during
2230 child process exits. [Brian Pane, Aaron Bannert]
2232 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
2234 *) Fix matching of vhosts by ip address so we find IPv4
2235 vhost address when target address is v4-mapped form of
2236 that address. [Jeff Trawick]
2238 *) More performance tweaks to the BNDM string-search algorithm
2239 used to find "<!--#" tokens in mod_include [Brian Pane]
2241 *) Miscellaneous small performance fixes: optimized away various
2242 string copy operations and removed large temp buffers from
2243 the stack [Brian Pane]
2245 *) Fixed startup segfault that occurred when a VirtualHost
2246 directive had a port but no address [Brian Pane]
2248 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
2250 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
2251 if oslevel < WINNT. This should fix several problems reported
2252 Against 2.0.28 on Windows 98 [Bill Stoddard]
2254 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
2255 to fail. [Bill Stoddard]
2257 *) Change core code to allow an MPM to set hard thread/server
2258 limits at startup. prefork, worker, and perchild MPMs now have
2259 directives to set these limits. [Jeff Trawick]
2261 *) Win32: The async AcceptEx() event should be autoreset upon
2262 successful completion of a wait (WaitForSingleObject). This
2263 eliminates a number of spurious
2264 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
2267 *) Move any load library path environment variables out of
2268 apachectl and into a separate environment variable file which
2269 can be more easily tailored by the admin. The environment
2270 variable file as built by Apache may have additional system-
2271 specific settings. For example, on OS/390 we tailor the heap
2272 settings to allow lots of threads. [Jeff Trawick]
2274 *) Use the new APR pool code to reduce pool-related lock
2275 contention in the worker MPM. [Sander Striker]
2277 *) The POD no longer assumes the child is listening on 127.0.0.1
2278 and now pulls the first hostname in the list of listeners to
2279 perform the dummy connect on. This fixes a bug when the user
2280 had configured the Listen directive for an IP other than
2281 127.0.0.1. This would result in undead children and error
2282 messages such as "Connection refused: connect to listener".
2285 *) The worker MPM now respects the LockFile setting, needed to
2286 avoid locking problems with NFS. [Jeff Trawick]
2288 *) Fix segfault when worker MPM receives SIGHUP.
2289 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
2291 *) Fix bug that could potentially prevent the perchild MPM from
2292 working with more than one vhost/uid. [Aaron Bannert]
2294 *) Change make install and apxs -i processing of DSO modules to
2295 perform special handling on platforms where libtool doesn't install
2296 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
2297 which prevented standard LoadModule statements from working.
2300 *) Whenever mod_so is enabled (not just when there are DSOs for
2301 our modules), do whatever special magic is required for compiling/
2302 loading third-party modules. This allows third-party DSOs to
2303 be used on an AIX build when there were no built-in modules
2304 built as DSOs. (This should help on OS/390 and BeOS as well.)
2307 *) Allow apxs to be used to build DSOs on AIX without requiring the
2308 user to hard-code the list of import files. (This should help
2309 on OS/390 and BeOS as well.) [Jeff Trawick]
2311 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
2312 PR 8563, 8919 [William Rowe]
2314 *) Get binary builds working when libapr and libaprutil are built
2317 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
2318 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
2319 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
2321 *) Fix the handling of SSI directives in which the ">" of the
2322 terminating "-->" is the last byte in a file [Brian Pane]
2324 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
2325 message that we had back in apache-1.3 and still have scattered
2326 throughout our docs. [Aaron Bannert]
2328 *) Prevent the Win32 port from continuing after encountering an
2329 error in the command line args to apache. [William Rowe]
2331 *) On a error in the proxy, make it write a line to the error log
2334 *) Various mod_ssl performance improvements [Doug MacEachern]
2336 Changes with Apache 2.0.29
2338 *) Add buffering in core_output_filter to ensure that long
2339 lists of small buckets don't cause small packet writes.
2340 [Brian Pane, Ryan Bloom]
2342 *) Fix the installation target to make sure that the manual is
2343 installed in the correct location.
2344 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
2345 Gomez Henri <hgomez@slib.fr>]
2347 *) Fix the cmd command for mod_include. When we are processing
2348 a cmd command, we do not want to use the r->filename to set
2349 the command name. The command comes from the SSI tag. To do this,
2350 I added a variable to the function that builds the command line
2351 in mod_cgi. This allows the include_cmd function to specify
2352 the command line itself. [Ryan Bloom]
2354 *) Change open_logs hook to return a value, allowing you
2355 to flag a error while opening logs
2356 [Ian Holsman, Doug MacEachern]
2358 *) Change post_config hook to return a value, allowing you
2359 to flag a error post config
2360 [Ian Holsman, Jeff Trawick]
2362 *) Allow SUEXEC_BIN (the path to the suexec binary that is
2363 hard-coded into the server) to be specified to the configure
2364 script by the --with-suexec-bin parameter. [Aaron Bannert]
2366 *) Fix segv in worker MPM following accept on pipe-of-death
2369 *) Add mod_deflate to experimental.
2370 [Ian Holsman, Justin Erenkrantz]
2372 *) Bail out at configure time if an invalid MPM was specified.
2373 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2375 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
2376 configured [John Sterling <sterling@covalent.net>]
2378 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
2380 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
2382 *) Optimization for the BNDM string-search function in
2383 mod_include. [Brian Pane]
2385 *) Fixed the behavior of the XBitHack directive.
2386 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
2388 *) The threaded MPM for Unix has been removed. Use the worker
2389 MPM instead. [various]
2391 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
2392 in logging the error from a failed DNS lookup. [Jeff Trawick]
2394 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
2397 *) Get mod_cgid killed when a MPM exits due to a fatal error.
2400 *) Fix a file descriptor leak in mod_include. When we include a
2401 file, we use a sub-request, but we didn't destroy the sub-request
2402 immediately, instead we waited until the original request was
2403 done. This patch closes the sub-request as soon as the data is
2404 done being generated. [Brian Pane <bpane@pacbell.net>]
2406 *) Allow modules that add sockets to the ap_listeners list to
2407 define the function that should be used to accept on that
2408 socket. Each MPM can define their own function to use for
2409 the accept function with the MPM_ACCEPT_FUNC macro. This
2410 also abstracts out all of the Unix accept error handling
2411 logic, which has become out of synch across Unix MPMs.
2414 *) Fix a bug which would cause the response headers to be omitted
2415 when sending a negotiated ErrorDocument because the required
2416 filters were attached to the wrong request_rec.
2417 [John Sterling <sterling@covalent.net>]
2419 *) Remove commas from the end of the macros that define
2420 directives that are used by MPMs. Prior to this patch,
2421 you would use these macros without commas, which was unlike
2422 the macros for any other directives. Now, the caller provides
2423 the comma rather than the macro providing it. This makes
2424 the macros look more like the rest of the directives.
2425 [Ryan Bloom and Cliff Woolley]
2427 *) Add 'redirect-carefully' environment option to disable sending
2428 redirects under special circumstances. This is helpful for
2429 Microsoft's WebFolders when accessing a directory resource via
2430 DAV methods. [Justin Erenkrantz]
2432 *) Begin to abstract out the underlying transport layer.
2433 The first step is to remove the socket from the conn_rec,
2434 the server now lives in a context that is passed to the
2435 core's input and output filters. This forces us to be very
2436 careful when adding calls that use the socket directly,
2437 because the socket isn't available in most locations.
2440 *) Really reset the MaxClients value in worker and threaded
2441 when the configured value is not a multiple of the number
2442 of threads per child. We said we did previously but we
2443 forgot to. [Jeff Trawick]
2445 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
2447 *) If shared modules are requested and mod_so is not available,
2448 produce a fatal config-time error. [Justin Erenkrantz]
2450 *) Improve http2env's performance by cutting the work it has to
2451 do. [Brian Pane <bpane@pacbell.net>]
2453 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
2454 [Brian Pane <bpane@pacbell.net>]
2456 Changes with Apache 2.0.28
2458 *) Fix infinite loop in mod_cgid.c.
2459 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
2461 *) When no port is given in a "ServerName host" directive, the
2462 server_rec->port is now set to zero, not 80. That allows for
2463 run-time deduction of the correct server port (depending on
2464 SSL/plain, and depending also on the current setting of
2465 UseCanonicalName). This change makes redirections
2466 work, even with https:// connections. As in Apache-1.3, the
2467 connection's actual port number is never used, only the ServerName
2468 setting or the client's Host: setting. Documentation updated
2469 to reflect the change. [Martin Kraemer]
2471 *) Add a '%{note-name}e' argument to mod-headers, which works in
2472 the same way as mod_log_confg. [Ian Holsman]
2474 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
2475 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
2476 MPMs. [Cliff Woolley]
2478 *) Introduce htdbm, a user management utility for db/dbm authorization
2479 databases. [Mladen Turk <mturk@mappingsoft.com>]
2481 *) Optimize usage of strlen and strcat in ap_directory_walk.
2482 [Brian Pane <bpane@pacbell.net>]
2484 Changes with Apache 2.0.27
2486 *) Introduce an Apache mod_ssl initial configuration template
2487 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
2489 *) Fixed a memory leak in the getline parsing code that could
2490 be triggered by arbitrarily large header lines. Requests
2491 from the core input filter for single lines are now limited
2492 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
2494 *) Fix a truncation bug in how we print the port on the Via: header.
2495 The routine that prints the Via: header now takes a length for
2496 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
2498 *) Some syntax errors in mod_mime_magic's magic file can result
2499 in a 500 error, which previously was unlogged. Now we log the
2500 error. [Jeff Trawick]
2502 *) Add the support/checkgid helper app, which checks the run-time
2503 validity of group identifiers usable in the Group directive.
2506 *) Various --enable-so options have been fixed: --enable-so is
2507 treated as "static"; explicit --enable-so=shared issues an error;
2508 and explicit --enable-so fails with error on systems without
2509 APR_HAS_DSO. [Aaron Bannert]
2511 *) Fix a segfault in the core input filter when the client socket
2512 gets disconnected unexpectedly. [Cliff Woolley]
2514 *) Fix the reporting for child processes that die. This removes
2515 all of the non-portable W* macros from Apache.
2516 [Jeff Trawick and Ryan Bloom]
2518 *) Win32: Track and display "Parent Server Generation:" in
2519 mod_status output. The generation will be bumped at
2520 server graceful restart, when the child process exits
2521 by hitting MaxRequestsPerChild or if the child
2522 process exits abnormally. [Bill Stoddard]
2524 *) Win32: Fix problem where MaxRequestsPerChild directive was
2525 not being picked up in favor of the default. Enable
2526 the parent to start up a new child process immediately upon
2527 the old child starting shutdown.
2530 *) Fix some bungling of the remote port in rfc1413.c so that
2531 IdentityCheck retrieves the proper user id instead of failing
2532 and thus always returning "nobody."
2533 [Dick Streefland <Dick.Streefland@xs4all.nl>]
2535 *) Introduced thread saftey for mod_rewrite's internal cache.
2536 [Brian Pane <bpane@pacbell.net>]
2538 *) Simplified mod_env's directives to behave as most directives are
2539 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
2540 directive following that UnsetEnv within the same container.
2541 Also provides a runtime startup warning if a PassEnv configured
2542 environment value is undefined. [William Rowe]
2544 *) The worker MPM is now completely ported to APR's new lock API. It
2545 uses native APR types for thread mutexes, cross-process mutexes,
2546 and condition variables. [Aaron Bannert]
2548 *) Sync up documentation to remove all references to the now deprecated
2549 Port directive. [Justin Erenkrantz]
2551 *) Moved all ldap modules from the core to httpd-ldap sub-project
2554 *) Exit when we can't listen on any of the configured ports. This
2555 is the same behavior as 1.3, and it avoids having the MPMs to
2556 deal with bogus ap_listen_rec structures. [Jeff Trawick]
2558 *) Cleanup the proxy code that creates a request to the origin
2559 server. This change adds an optional hook, which allows modules
2560 to gain control while the request is created if the proxy module
2561 is loaded. The purpose of this hook is to allow modules to add
2562 input and/or output filters to the request to the origin. While
2563 I was at it, I made the core use this hook, so that proxy request
2564 creation uses some of the code from the core. This can still be
2565 greatly improved, but this is a good start. [Ryan Bloom]
2567 Changes with Apache 2.0.26
2569 *) Port the MaxClients changes from the worker MPM to the threaded
2572 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
2573 with the new input filtering system. [Justin Erenkrantz]
2575 *) Introduce the MultiviewsMatch directive, to allow the operator
2576 to be flexible in recognizing Handlers and Filters filename
2577 extensions as part of the Multiviews matching logic, strict with
2578 MultiviewsMatch NegotiatedOnly to accept only filename extentions
2579 that designate negotiated parameters, (content type, charset, etc.)
2580 or MultiviewsAll for the 1.3 behavior of matching any files, even
2581 if they have unregistered extensions. [William Rowe]
2583 *) Fixed the configure script to add a LoadModule directive to
2584 the default httpd.conf for any module that was compiled
2585 as a DSO. [Aaron Bannert <aaron@clove.org>]
2587 *) rewrite mod_ssl input filtering to work with the new input filtering
2588 system. [Justin Erenkrantz]
2590 *) prefork: Don't segfault when we are able to listen on some but
2591 not all of the configured ports. [Jeff Trawick]
2593 *) Build mod_so even if no core modules are built shared.
2594 [Aaron Bannert <aaron@clove.org>]
2596 *) Introduce ap_directory_walk rewrite (with further optimizations
2597 required) to adapt to the ap_process_request_internal() changes.
2598 Optimized so subrequests and redirects now reuse previous section
2599 merges, until we mismatch with the original directory_walk, and
2600 precomputed r->finfo results will cause directory_walk to skip
2601 the most expensive phases of the function. [William Rowe]
2603 *) Allow ApacheMonitor to connect to and control Apache on other
2604 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
2606 *) Remove the Port directive. In it's place, the Listen directive
2607 is now a required directive, which tells Apache what port to
2608 listen on. The ServerName directive has also been extended
2609 to accept an optional port. If the port is specified to the
2610 ServerName, the server will report that port whenever it
2611 reports the port that it is listening on. This change was
2612 made to ease configuration errors that stem from having a Port
2613 directive, and a Listen directive. In that situation, the server
2614 would only listen to the port specified by the Listen command,
2615 which caused a lot of confusion to users. [Ryan Bloom]
2617 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
2618 build, as loadable modules. [William Rowe]
2620 *) Fix --enable-mods-shared processing. If most is specified,
2621 then all modules that can be compiled as shared modules are.
2622 [Aaron Bannert <aaron@clove.org>]
2624 *) Update the mime.types file to map video/vnd.mpegurl to mxu
2625 and add commonly used audio/x-mpegurl for m3u extensions.
2626 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
2628 *) Eliminate the depreciated r->content_language, in favor of the array
2629 r->content_languages introduced many years ago. Module authors must
2630 substantially overhaul their modules, so this needs to be upgraded
2631 if the module still relied on backwards-brokeness. [William Rowe]
2633 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
2636 *) Rewrite the input filtering mechanisms to consolidate and reorganize
2637 code. In short, core_input_filter does something now and
2638 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
2640 *) Update the Win32 build to re-absorb mod_proxy and family.
2643 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
2644 current SDK.) [William Rowe]
2646 *) Some style changes to the code that does ProxyErrorOverride. Fixed
2647 config merge behaviour. [Graham Leggett]
2649 *) Allow support programs to be compiled against a static version
2650 of libapr. This allows the smaller support programs to be
2651 relocated. [Aaron Bannert <aaron@clove.org>]
2653 *) Update the mime.types file to the registered media types as
2654 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
2656 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
2657 number of clients that can connect at the same time, instead of
2658 specifying the maximum number of child processes.
2659 [Aaron Bannert <aaron@clove.org>]
2661 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
2662 be consistent with 1.3. [Justin Erenkrantz]
2664 *) Cache apr_explode_localtime() value for 15 seconds.
2665 [Brian Pane <bpane@pacbell.net>]
2667 *) Fix mod_include to not return ETag or Last-Modified headers.
2668 [Ian Holsman <ianh@cnet.com>]
2670 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
2672 *) Eliminate the wasteful run-time conversion of method names from strings
2673 to numbers in places where the methods are known at compile time.
2674 [Brian Pane <bpane@pacbell.net>]
2676 *) Turn the worker MPM's queue into a LIFO. This may
2677 improve cache-hit performance under some conditions.
2678 [Aaron Bannert <aaron@clove.org>]
2680 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
2681 support it. [Justin Erenkrantz]
2683 *) Cleanup the worker MPM. We no longer re-use transaction
2684 pools. This incurs less overhead than shuffling the pools
2685 around so that they can be re-used. Remove one of the
2686 queue's condition variables. We just redefined the API to
2687 state that you can't try to add more stuff than you allocated
2688 segments for. [Aaron Bannert <aaron@clove.org>]
2690 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
2692 *) Fixed persistent connections when a request contains a body.
2695 *) mod_dav uses a new API to speak to the backend provider for dead
2696 property management. [Greg Stein]
2698 *) Remove the Win32 script-processing exception from mod_cgi, and
2699 roll build_command_line/build_argv_list into a unified, overrideable
2700 ap_cgi_build_command optional function. [William Rowe]
2702 *) Rewrite find_start_sequence to use a better search algorithm
2703 to find the start tag. [Justin Erenkrantz]
2705 *) Fix a seg fault in mod_include. When we are generating an
2706 internal redirect, we must set r->uri to "", not a bogus
2707 string, and not NULL. [Ryan Bloom]
2709 *) Optimized location_walk, so subrequests, redirects and second passes
2710 now reuse previous section merges on a <Location > by <Location >
2711 basis, until we mismatch with the original location_walk.
2714 *) Back out the 1.45 change to util_script.c. This change made
2715 us set the environment variable REQUEST_URI to the redirected
2716 URI, instead of the originally requested URI.
2717 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2719 *) Make mod_include do lazy evaluation of potentially expensive to
2720 compute variables. [Brian Pane <bpane@pacbell.net>]
2722 *) Fix logging of bytes sent for HEAD requests. %b and %B should
2723 log either - or 0, before this patch, they were both logging
2724 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2726 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
2727 than per character. [Brian Pane <bpane@pacbell.net>]
2729 *) Normalize the primary request, redirects and sub-requests to
2730 run the same ap_process_request_internal for consistency in
2731 robustness, behavior and security. [William Rowe]
2733 *) Fix a segfault with mod_include when r->path_info is not set
2734 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
2736 *) Add -X functionality back. This indicates to all MPMs and any other
2737 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
2739 *) Some initial support for the cygwin platform [prefork only].
2740 This is not to be confused with support for the WinNT/Win32
2741 platform, which is the recommended configuration for native
2742 Win32 users. The cygwin platform support is recommended for
2743 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
2745 *) Changed syntax of Set{Input|Output}Filter. The list of filters
2746 must be semicolon delimited (if more than one filter is given.)
2747 The Set{Input|Output}Filter directive now overrides a parent
2748 container's directive (e.g. SetInputFilter in <Directory /web/foo>
2749 will override any SetInputFilter directive in <Directory /web>.)
2750 This new syntax is more consistent with Add{Input|Output}Filter
2751 directives defined in mod_mime. Also cures a bug in prior releases
2752 where the Set{Input|Output}Filter directive would corrupt the
2753 global configuration if the multiple directives were nested.
2756 *) Cured what's ailed mime for quite some time. If an AddSomething
2757 was given in the configuration (Language, Charset, Handler or
2758 Encoding) Apache would set the content type as given by AddType,
2759 but refused to check the mime.types file if AddType wasn't given
2760 for that specific extension. Setting the AddHandler for .html
2761 without setting the AddType text/html html would cause Apache to
2762 use the default content type. [William Rowe]
2764 *) Added some bulletproofing to memory allocation in the LDAP cache
2765 code. [Graham Leggett]
2767 Changes with Apache 2.0.25
2769 *) Move the installed /manual directory out of the /htdocs/ tree, so
2770 that it can be kept more independently from the remaining document
2771 root. The "Alias /manual ..." already allowed for easy projection
2772 into existing private document trees. [Martin Kraemer]
2774 *) Add specified user attributes to the environment when using
2775 mod_auth_ldap. This allows you to use mod_include to embed specified
2776 user attributes in a page like so:
2777 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
2780 *) Fix a performance problem with the worker MPM. We now create
2781 transaction pools once, and re-use them for each connection.
2782 [Aaron Bannert <aaron@clove.org>]
2784 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
2785 of a 'handler' or 'filter', so that any filename extension that does
2786 not contribute to the negotiated metadata can't be served without
2787 an explicit request. E.g., if the .Z extension is associated with
2788 an unzip filter, the user request somefile.Z.html, mod_negotiation
2789 won't serve it. It can serve somefile.Z.html when somefile.Z is
2790 requested, since the .Z extension is explictly requested, if the
2791 .html extension is associated with ContentType text/html.
2794 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
2795 and corresponding AddOutputFilter syntax, to insert one or more
2796 filters by mod_mime filename extension processing.
2799 *) Fix a growing connection pool in core_output_filter() for
2800 keepalive requests. [Jeff Trawick]
2802 *) Moved split_and_pass_pretag_buckets back to being a
2803 macro at Ryans's request. Removed the return from it
2804 by setting and returning a return code instead. Updated
2805 the code to check the return code from the macro and
2806 do the right thing. [Paul J. Reder]
2808 *) Fix a segfault when a numeric value was received for Host:.
2811 *) Add a function ap_remove_input_filter. This is to match
2812 up with ap_remove_output_filter. [Ryan Bloom]
2814 *) Clean up location_walk, so that this step performs a minimum
2815 amount of redundant effort (it must be run twice, but it will no
2816 longer reparse all <Location > blocks when the request uri
2817 hadn't changed.) [William Rowe]
2819 *) Eliminate proxy: (and all other 'special') processing from the
2820 ap_directory_walk() phase. Modules that want to use special
2821 walk logic should refer to the mod_proxy map_to_location example,
2822 with it's proxy_walk and proxysection implementation. This makes
2823 either directory_walk flavor much more legible, since that phase
2824 only runs against real <Directory > blocks.
2827 *) SECURITY: Fix a security problem in mod_include which would allow
2828 an SSI document to be passed to the client unparsed.
2829 [Cliff Woolley, Brian Pane]
2831 *) Introduce the map_to_storage hook, which allows modules to bypass
2832 the directory_walk and file_walk for non-file requests. TRACE
2833 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
2834 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
2837 *) Add the ability for mod_include to add the INCLUDES filter
2838 if the file is configured for the server-parsed handler.
2839 This makes the configuration for .shtml files much easier
2840 to understand, and allows mod_include to honor Apache 1.3
2841 config files. Based on Doug MacEachern's patch to PHP
2842 to do the same thing. [Ryan Bloom]
2844 *) force OpenSSL to ignore process local-caching and to always
2845 get/set/delete sessions using mod_ssl's callbacks
2846 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
2847 Geoff Thorpe <geoff@geoffthorpe.net>]
2849 *) Make the worker MPM shutdown and restart cleanly. This also
2850 cleans up some race conditions, and gets the worker using
2851 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
2853 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
2855 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2857 *) Fix for mod_include. Ryan's patch to check error
2858 codes put a return in the wrong place. Also, the
2859 include handler return code wasn't being checked.
2860 I don't like macros with returns, so I converted
2861 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
2862 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2864 *) fix segv in mod_mime if no AddTypes are configured
2865 [John Sterling <sterling@covalent.net>]
2867 *) Enable ssl client authentication at SSL_accept time
2868 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2870 *) Fix a segfault in mod_include when the original request has no
2871 associated filename (e.g., we're filtering the error document for
2872 a bad URI). [Jeff Trawick]
2874 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
2876 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
2877 of httpd is started and shuts down due to socket conflict. Moving the
2878 call to ap_log_pid solves the problem.
2880 *) Changed the late-1.3 log_config substitution %c to %X, to log the
2881 status of the closed connection, as it conflicts with the far more
2882 common, historical ssl logging directive %...{var}c. [William Rowe]
2884 *) Added the common error/ tree to the build/install targets
2885 (similar to the common icons/ tree) for the multi-language error
2886 messages that Lars committed earlier. [William Rowe]
2888 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
2890 *) Added a default commented-out mod_ldap and mod_auth_ldap
2891 configuration to httpd-std.conf and httpd-win.conf
2894 *) Added documentation for mod_ldap and mod_auth_ldap.
2897 *) Enabled negative caching on attribute comparisons in the LDAP cache.
2898 Fixed a problem where the default cache TTL was set in milliseconds
2899 not microseconds causing the cache to time out almost immediately.
2902 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
2903 module code to follow APR. [Graham Leggett]
2905 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
2906 cleaned up when the connection pool pool is cleaned up.
2909 *) Fix a minor issue with Jeff Trawick's mod_include
2910 patch. Without this patch, the code will just allocate
2911 more bytes in get_combined_directive than are needed.
2914 *) Added the LDAP authentication module mod_auth_ldap.
2915 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
2917 *) Added the LDAP cache and connection pooling module mod_ldap.
2918 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
2920 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
2921 by allowing a module to disable itself if its prerequisites are not
2922 met. [Justin Erenkrantz]
2924 Changes with Apache 2.0.24
2926 *) Fix a couple of issues in mod_include when the tag appeared at
2927 offsets near 8192 in the file being parsed. [Jeff Trawick]
2929 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
2930 reached. [Jeff Trawick]
2932 *) Numerous improvements to the Win32 build system. Introduced command line
2933 builds without requiring .mak files for MSVC 6.0 and later versions.
2934 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
2937 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
2938 reporting of uninstalled services and other error conditions, and changed the
2939 default service name to Apache2. [William Rowe]
2941 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
2942 compatibility with existing Apache 1.3 Win32 Apache management utilites.
2943 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
2945 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
2946 [William Rowe, Greg Ames]
2948 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
2949 and RemoveCharset directives. [William Rowe]
2951 *) The Unix MPMs other than perchild now allow child server
2952 processes to use the accept mutex when starting as root and
2953 using SysV sems for the accept mutex. Previously, this
2954 combination would lead to fatal errors in the child server
2955 processes. perchild can't use SysV sems because of security
2956 issues. [Jeff Trawick, Greg Ames]
2958 *) Added Win32 revision stamp resources to all http binaries
2959 (including modules/ and support/ tools.) PR7322 [William Rowe]
2961 *) Fix ap_rvprintf to support more than 4K of data at one time.
2962 [Cody Sherr <csherr@covalent.net>]
2964 *) We have always used the obsolete/deprecated Netscape syntax
2965 for our tracking cookies; now the CookieStyle directive
2966 allows the Webmaster to choose the Netscape, RFC2109, or
2967 RFC2965 format. The new CookieDomain directive allows the
2968 setting of the cookie's Domain= attribute, too. PR #s 5006,
2969 5023, 5920, 6140 [Ken Coar]
2971 *) Tweak server/Makefile so that the rules for generating exports.c
2972 are compatible with make utilities which don't expand wildcards
2973 in a dependency list (e.g., OS/390 make, certain levels of GNU
2974 make). [Jeff Trawick]
2976 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
2978 *) Begin to sanitize the MPM configuration directives. Now, all
2979 MPMs use the same functions for all common MPM directives. This
2980 should make it easier to catch all bugs in these directives once.
2981 [Cody Sherr <csherr@covalent.net>]
2983 *) Close a major resource leak. Every time we had issued a
2984 graceful restart, we leaked a socket descriptor.
2987 *) Fix a problem with the new method code. We need to cast
2988 the 1 to an apr_int64_t or it will be treated as a 32-bit
2989 integer, and it will wrap after being shifted 32 times.
2990 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
2992 *) Fix a bug in mod_expires. Previous to this patch, if you
2993 told mod_expires to add 604800 seconds to the last-modified
2994 time, it actually added 604800 usec's to the last-modified time,
2995 so that when looking at the response it looked like nothing
2996 had been done. The root of the problem was that we always compute
2997 time in usec's, but we ask users to input sec's. This means we
2998 need to convert to usec's before using those values.
3001 *) The worker MPM now handles shutdown and restart requests. It
3002 definitely isn't perfect, but we do stop the servers correctly.
3003 The biggest problem right now is that SIGHUP causes the server to
3004 just die. [Ryan Bloom]
3006 Changes with Apache 2.0.23
3008 *) Use the prefork MPM by default on Unix. [various]
3010 *) Added a systray icon monitor application for Win32.
3011 [Mladen Turk <mturk@mappingsoft.com>]
3013 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3014 messages written to the rewrite log.
3015 [Richard Labennett <rlabenn@us.ibm.com>]
3017 *) All mod_autoindex query parsing is now quietly quashed with the
3018 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3019 still drops the column sort <a href>'s for the column headers, but
3020 IgnoreClient is required to ignore these Query options entirely.
3023 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3024 to allow the client to select plain, FancyIndexing or HTMLTable
3025 formatting, V=[0|1] to inhibit or enable version sorting, and
3026 P=pattern to return only specific files. The old Query Arguments
3027 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3028 as before), and O=A|D for ordering ascending or descending.
3031 *) Fixed an error in mod_include's directive parsing routines which
3032 caused #if, #elif, and #else expressions containing backslashes
3033 to be improperly evaluated. [Cliff Woolley]
3035 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3036 drop the icon column, SuppressRules to drop the <hr> elements,
3037 and HTMLTable to create rudimentary HTML table listings (implies
3038 FancyIndexing). [William Rowe]
3040 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3041 from Apache 1.3.15. This is needed for two reasons, first, given
3042 multiple machines within a server farm, ETags and Last-Modified
3043 stamps won't correspond from machine to machine, and second, many
3044 Unixes don't capture changes to the date or time stamp of existing
3045 files, since these don't modify the dirent itself. [William Rowe]
3047 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3048 and DirectoryWidth options from Apache 1.3.10.
3049 [William Rowe, Ken Coar]
3051 *) Eliminated FancyIndexing directive, deprecated early in Apache
3052 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3054 *) mod_autoindex now excludes any file names that would result in
3055 an error, other than a success or redirect. Also optimized
3056 the parent directory, always included except in the URI '/'.
3059 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3060 negotiated index pages, and prevent the server from defaulting
3061 to an autoindex of the directory. mod_negotiation will now die
3062 with a 500 Internal Error if it could match some filenames
3063 (e.g. for mod_dir) but none can be served. mod_negotation now
3064 refuses to serve any file with an extention that mod_mime doesn't
3065 recognize, and wasn't part of the request. [William Rowe]
3067 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3068 extension. This is already handled by multiviews, if the admin
3069 wishes to AddHandler .exe or define a content type handler and
3070 associate .exe files with that content type. Multiviews must be
3071 enabled to allow these to be served. [William Rowe]
3073 *) Speed up the server's response to a spike in incoming workload
3074 or restarts by assigning empty scoreboard slots to new processes
3075 when they are available. [Greg Ames]
3077 *) Add a handler to mod_includes.c. This handler is designed to
3078 implement the XbitHack directive. This can't be done with a
3079 fixup, because we need to check the content-type, which is
3080 only available in the handler phase. [Ryan Bloom]
3082 *) Make the includes filter check return codes from filters lower in
3083 the filter chain. If a lower level filter returns an error, then
3084 the request needs to stop immediately. This allows mod_include to
3085 stop parsing data once a lower filter recognizes an error.
3088 *) Add the ability to extend the methods that Apache understands
3089 and have those methods <limit>able in the httpd.conf. It uses
3090 the same bit mask/shifted offset as the original HTTP methods
3091 such as M_GET or M_POST, but expands the total bits from an int to
3092 an ap_int64_t to handle more bits for new request methods than
3093 an int provides. [Cody Sherr <csherr@covalent.net>]
3095 *) Fix broken mod_mime behavior in merging its arguments. Possible
3096 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
3098 *) Solve many mod_ssl porting issues (too many to detail) with
3099 help from the whole team, but most notably [Ralf S. Engelschall,
3100 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
3101 Doug MacEachern, William Rowe, Cliff Woolley]
3103 *) More stall fixes for the threaded & worker mpm's.
3104 Make mod_status output more accurate. Don't
3105 count workers in processes which aren't actively
3106 serving requests. [Greg Ames]
3108 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
3110 *) Add a single listener/multiple worker MPM. This MPM is
3111 definately not fully correct, but it allows us to solve many
3112 of the problems that exist in the threaded MPM. This is a
3113 modified version of the threaded MPM. [Ryan Bloom]
3115 *) Improve content generation throughout Apache, providing closer
3116 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
3117 Transitional specifications. [William Rowe]
3119 Changes with Apache 2.0.22
3121 *) Fix a problem where the threaded MPM stalls after restarts or
3122 segfaults. Also prevent multiple active processes from using
3123 the same scoreboard slot. [Greg Ames]
3125 *) Apache/Win32 now fills in the service description with Apache's
3126 server version string, including loaded and advertised modules.
3129 *) Improved support for the Win32 build, to recover gracefully from
3130 missing apr or apr-util directories or the awk interpreter,
3131 create the proper cgi-bin examples, including a test-cgi.bat, and
3132 fix the perl shebang line for printenv.pl, when installing from
3133 the build environment. [William Rowe]
3135 *) Fix a segfault in threaded.c caused by passing uninitialized
3136 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
3138 *) Use new APR number conversion functions to reduce CPU consumption
3139 when setting the content length, and in mod_log_config.
3142 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
3143 where HEAD response headers were being repeated twice for
3144 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
3145 problem in the http_header filter was exposed by the recent rewrite
3146 of the content_length filter. [Taketo Kabe, Bill Stoddard]
3148 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
3149 restarts. A garbage pointer to a vhost's server_rec from the
3150 previous generation was being left around under certain
3151 conditions. [Greg Ames]
3153 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
3154 used to appear as '(none', without the closing paren.
3155 [Günter Knauf <eflash@gmx.net>]
3157 *) Improve the exports generating awk script. In the past, we had
3158 work around problems in the awk script by avoiding some #if and
3159 #ifdefs. This has bitten us many times in generating the exports.c
3160 file. This improvement allows corrects the header file parsing.
3161 [Sander Striker <striker@apache.org>]
3163 Changes with Apache 2.0.21
3165 *) Resolve the Win32 htpasswd bug, where a file that existed would be
3166 overwritten, regardless of the -c flag.
3167 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
3169 *) Introduce connection sub-pools into ab. Truncating the lifetime
3170 of these allocations means that ab no longer perpetually grows
3171 its working set, running out of memory on large request attempts.
3174 *) Make scoreboard creation a hook. This allows management
3175 modules to have access to the scoreboard at the time that it is
3176 created, and at every restart request.
3177 [Cody Sherr <csherr@covalent.net>]
3179 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
3180 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
3181 daemon index actually used in the scoreboard. I also
3182 updated the pertinent calls. [Paul J. Reder]
3184 *) Win32: Prevent listening sockets from being inherited by
3185 the Apache child process, CGI scripts, rotatelog process
3186 etc. If the Apache child process segfaults, any processes
3187 that the child started are not reaped. Prior to this fix,
3188 these processes inherited the listening sockets which sometimes
3189 prevented the restarted Apache child process from accepting
3190 connections (ie, the server would hang).
3193 *) Provide vhost and request strings when ExtendedStatus is on.
3196 *) Fix some issues with the pod and prefork: check the pod *after*
3197 processing a connection so that a server processing a time-
3198 consuming request bails out as soon as practical; when the
3199 parent process wakes up a server process via connect(), use an
3200 APR timeout on the connect() so that we don't hang for a long
3201 time if there aren't server processes around to do accept().
3202 [Jeff Trawick, Greg Ames]
3204 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
3205 spends a lot of time in apr_table_get calls. Using the default
3206 httpd.conf, the tables for languages and charsets are somewhat
3207 large, so the time spent scanning them on each request is
3208 significant. Replacing the tables with hash tables provides
3209 a nice speedup. [Brian Pane <bpane@pacbell.net>]
3211 *) Add two functions to allow modules to access random parts of the
3212 scoreboard. This allows modules compiled for one MPM to access the
3213 scoreboard, even if it the server was compiled for another MPM.
3214 [Harrie Hazewinkel <harrie@covalent.net>]
3216 Changes with Apache 2.0.20
3218 *) Fix problem in content-length filter where the filter would
3219 buffer all the output from a CGI before sending any bytes
3220 down the filter stack to the network. This problem would cause
3221 significant memory consumption if the CGIs generated
3222 lots of bytes. [Bill Stoddard]
3224 *) Get non-blocking CGI pipe reads working with the bucket brigades.
3227 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
3230 *) Fix a bug in the threaded MPM that would cause it to kill off all
3231 workers immediately after starting if the number of workers started
3232 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
3234 Changes with Apache 2.0.19
3236 *) Fix problem with threaded MPM. The problem was that if each child
3237 process was busy serving a single long-lived request and the server
3238 was sent a graceful restart signal, the server would stop serving
3239 requests. This would happen because each child process would wait to
3240 die until the last thread was done, and the parent wouldn't spawn any
3241 new children until a process died. Now, the parent looks at the fact
3242 that the children are dying gracefully, and starts new children.
3243 Those new children only start enough threads to compliment the number
3244 of threads in the other child process that shares the same spot in
3245 the scoreboard. In this way, we make sure to never go over
3246 MaxClients. [Ryan Bloom]
3248 *) modified mod_negotiation and mod_autoindex to speed up by almost a
3249 factor of two on apr_dir_read()-enhanced platforms, such as Win32
3250 and OS2, by calling ap_sub_request_lookup_dirent() with the results
3251 already provided by apr_dir_read(). [William Rowe]
3253 *) mod_file_cache is now more robust to filtering and serves requests
3254 slightly more efficiently. [Cliff Woolley]
3256 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
3257 Module was calling ap_rwrite() followed by ap_rflush() but the
3258 served content was not being displayed in the browser. Inspection
3259 of the output stream revealed that the first data chunk was
3260 missing the trailing CRLF required by the RFC. [Bill Stoddard]
3262 *) apxs no longer generates ap_send_http_header() in the example handler
3264 *) Fix an ab problem which could cause a divide-by-zero exception
3265 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
3266 [Ian Holsman <ianh@cnet.com>]
3268 *) Solve case-insensitive platforms' confusion about negotiated
3269 filenames, allowing files of differnt case to match in choosing
3270 the document to serve. [William Rowe]
3272 *) Fix brokenness when ThreadsPerChild is higher than the built-in
3273 limit. We left ap_threads_per_child at the higher value which
3274 led to segfaults when doing certain scoreboard operations.
3277 *) Fix seg faults and/or missing output from mod_include. The
3278 default_handler was using the subrequest pool for files and
3279 MMAPs, even though the associated APR structures typically
3280 live longer than the subrequest. [Greg Ames]
3282 *) Extend mod_setenvif to support specifying regular expressions
3283 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
3284 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
3285 will cause HAVE_TS to be set if any of the request headers begins
3286 with "TS" and has a value that begins with any character in the
3287 set [a-z]. [Bill Stoddard]
3289 *) httpd children now re-bind themselves to a random CPU on
3290 multiprocessor systems on AIX via bindprocessor() in 2.0.
3291 [Victor J. Orlikowski]
3293 *) Fix htdigest. It would go into a loop in getline when adding
3294 a second user. [Bill Stoddard]
3296 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
3298 *) Automatically generate httpd.exp for AIX.
3299 DSOs now work again on AIX in 2.0
3300 [Victor J. Orlikowski]
3302 *) Add a new request hook, error_log. This phase allows modules
3303 to act on the error log string _after_ it has been written
3304 to the error log. The goal for this hook is to allow monitoring
3305 modules to send the error string to the monitoring agent.
3308 *) Modify mod_echo to make it use filters for input and output.
3309 [Ryan Morgan <rmorgan@covalent.net>]
3311 *) Extend mod_headers to support conditional driven Header
3312 add, append and set. Use SetEnvIf to set an envar and conditionally
3313 add/append/set headers based on this envar thusly:
3315 SetEnvIf TSMyHeader value HAVE_TSMyHeader
3316 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
3318 If the request contains header "TSMyHeader: value" then header
3319 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
3322 *) Extend mod_headers to support using format specifiers on Header
3323 add, append and set header values. Two format specifiers are supported:
3325 %t - reports, in UTC microseconds since the epoch, when the
3326 request was received.
3328 %D - reports the time, in microseconds, between when the request was
3329 received and the response sent.
3332 Header add MyHeader "This request served in %D microseconds. %t"
3334 results in a header being added to the response that looks like this:
3336 MyHeader: This request served in D=5438 microseconds. t=991424704447256
3340 *) Fix reset_filter(). We need to be careful how we remove filters.
3341 If we set r->output_filters to NULL, we also have to reset the
3342 connection's filters. [John Sterling]
3344 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
3346 *) Add a check to ap_die() to make sure the filter stack is sane and
3347 contains the correct basic filters when an error occurs. This fixes
3348 a problem where headers are not being sent on error. [John Sterling]
3350 *) New Header directive 'echo' option. "Header echo regex" will
3351 cause any headers received on the request that match regex to be
3352 echoed to (included in) the response headers.
3355 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
3356 This prevented the inclusion of apr_compat.h. PR #7773
3357 [Oleg Broytmann <phd@phd.pp.ru>]
3359 *) Moved util_uri to the apr-util library. This required a bunch of
3360 apr_name changes for the uri utility functions. [Justin Erenkrantz]
3362 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
3363 insert_filter phase so that other filters are not bypassed by default.
3366 *) Reimplement mod_headers as an output filter. mod_headers can now
3367 add custom headers to inbound requests using the RequestHeader directive
3368 and to responses using the same old Header directive. [Graham Leggett]
3370 Changes with Apache 2.0.18
3372 *) Fix command-line processing so that if a bad argument is specified
3373 Apache will exit. [Jeff Trawick]
3375 *) Change the make targets and rules to be consistent in all of the
3376 Apache-owned source trees. [Roy Fielding]
3378 *) Fix processing of the TRACE method. Previously we passed bogus
3379 parms to form_header_field() and it overlaid some vhost structures,
3380 resulting in a segfault in check_hostalias().
3381 [Greg Ames, Jeff Trawick]
3383 *) Win32: Add support for reliable piped logs. If the logging process
3384 goes down, Apache will automatically restart it. This function has
3385 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
3388 *) Do not start piped log processes during the config file
3389 preflight. This change also circumvents a problem on
3390 Windows where the rotatelog processes created during preflight
3391 was not getting cleaned up properly.
3394 *) add "Request Phase Participation" info to mod_info
3397 *) Make first phase changes to the scoreboard data structures in
3398 preparation for the rewriting of the scoreboard per my posted
3399 design notes. [Paul J. Reder]
3401 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
3402 and apr-util, allow it to be overridden by the configure command-line
3403 (default="--silent") and introduce LT_LDFLAGS to replace what we were
3404 formerly abusing as LTFLAGS. [Roy Fielding]
3406 *) Clean up the reporting of incorrect closing container tags.
3407 [Barrie Slaymaker <barries@slaysys.com>]
3409 *) Simplify the configure process by moving all libtool stuff to APR
3410 and moving hints.m4 inline. [Roy Fielding]
3412 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
3413 of functions used by mod_proxy for export in the DLL
3414 [Ian Holsman <IanH@cnet.com>]
3416 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
3417 request body from its stdin but no reqest body is being written to
3418 the cgi. [Jeff Trawick]
3420 *) mod_log_config: %c connection status incorrectly logged
3421 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
3424 *) Get mod_cern_meta working under Windows
3427 *) Create Files, and thus MMAPs, out of the request pool, not the
3428 connection pool. This solves a small resource leak that had us
3429 not closing files until a connection was closed. In order to do
3430 this, at the end of the core_output_filter, we loop through the
3431 brigade and convert any data we have into a single HEAP bucket
3432 that we know will survive clearing the request_rec.
3433 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
3436 *) Completely revamp configure so that it preserves the standard make
3437 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
3438 the configure additions to EXTRA_* variables. Also, allow the user
3439 to specify NOTEST_* values for all of the above, which eliminates the
3440 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
3441 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
3442 avoid pointless duplications. Fix the order in which flags are given
3443 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
3444 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
3445 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
3446 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
3448 *) Get mod_tls to compile/work better on Windows. PR #7612
3449 [Bernhard Schrenk <b.schrenk@improx.com>]
3451 *) Fix shutdown/restart hangs in the threaded MPM.
3452 [Jeff Trawick, Greg Ames, Ryan Bloom]
3454 *) Removed the keptalive boolean from conn_rec because it is now only
3455 used by a single routine and can be replaced by a local variable.
3456 [Greg Stein, Ryan Bloom, Roy Fielding]
3458 *) Patch prefork to put enough of the signal processing back in so that
3459 signals are all handled properly now. The previous patch fixed the
3460 deadlock race condition, but broke the user directed signal handling.
3461 This fixes it to work the way it did before my previous prefork patch
3462 (primarily, SIGTERM is now working).
3464 *) Change how input filters decide how much data is returned to the
3465 higher filter. We used to use a field in the conn_rec, with this
3466 change, we use an argument to ap_get_brigade to determine how much
3467 data is retrieved. [Ryan Bloom]
3469 *) Fix seg fault at start-up introduced by Ryan's change to enable
3470 modules to specify their own logging tags. mod_log_config
3471 registers an optional function, ap_register_log_handler().
3472 ap_register_log_handler() was being called by http_core before
3473 the directive hash table was created. This patch creates the
3474 directive hash table before ap_register_log_handler() is
3475 registered as an optional function.
3476 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
3478 *) Add ap_set_int_slot() function
3479 [John K. Sterling <sterling@covalent.net>]
3481 *) Under certain circumstances, Apache did not supply the
3482 right response headers when requiring authentication.
3483 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
3484 (This is a port of the change that went into Apache 1.3.19.)
3486 *) Allow modules to specify their own logging tags. This basically
3487 allows a module to tell mod_log_config that when %x is encountered
3488 a specific function should be called. Currently, x can be any single
3489 character. It may be more useful to make this a string at some point.
3492 Changes with Apache 2.0.17
3494 *) If a higher-level filter handles the the byterange aspects of a
3495 request, then the byterange filter should not try to redo the
3496 work. The most common case of this happening, is a byterange
3497 request going through the proxy, and the origin server handles
3498 the byterange request. The proxy should ignore it.
3499 [Graham Leggett <minfrin@sharp.fm>]
3501 *) Changed the threaded mpm to have child_main join to each of the
3502 worker threads to make sure the kids are all gone before child_main
3503 exits after a signal (cleanup from perform_idle_server_maintenance).
3504 This is an extension of Ryans recent commit to make the child_main
3507 *) Add more options to the ap_mpm_query function. This also allows MPMs to
3508 report if their threads are dynamic or static. Finally, this also
3509 implements a new API, ap_show_mpm, which returns the MPM that was
3510 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
3512 *) Do not install the binaries from the support directory twice.
3513 [jun-ichiro hagino <itojun@iijlab.net>]
3515 *) The ap_f* functions should flush data to the filter that is passed
3516 in, not the the filter after the one passed in.
3517 [Ryan Morgan <rmorgan@covalent.net>]
3519 *) Make ab work again by changing its native types to apr types and formats.
3520 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3522 *) Move the byterange filter and all of the supporting functions back
3523 to the HTTP module. The byterange filter turned out to be very
3524 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
3526 *) Make clean, distclean, and extraclean consistently according to the
3527 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3529 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
3530 This may have been causing problems stopping processes in the threaded
3533 *) Fix content-length in mod_negotiation to a long int representation.
3536 *) Remove BindAddress from the default config file.
3537 [giles@nemeton.com.au]
3539 *) Allow module authors to add a module to their Apache build using
3540 --with-module, without re-running buildconf. The syntax is:
3541 --with-module=module_type:/path/to/module.c
3542 The configure script will copy the module.c file to
3543 modules/module_type, and it will be added to the relevant Makefiles.
3544 currently, this only works for static modules. [Ryan Bloom]
3546 *) Changes required to make prefork clean up idle children properly.
3547 There was a window during which a starting worker deadlocks when
3548 an idle cleanup arrives before it completes init. Apache then keeps
3549 trying to cleanup the same deadlocked worker forever (until higher
3550 pids come along, but it still will never reduce below the deadlocked
3551 pid). Thus the number of children would not reduce to the correct
3552 idle level. [Paul J. Reder]
3554 Changes with Apache 2.0.16
3556 *) Change the default installation directory to /usr/local/apache2,
3557 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
3559 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
3562 *) Get MaxRequestsPerChild working with the Windows MPM.
3565 *) Make generic hooks to work, with mod_generic_hook_import/export
3566 experimental modules. [Ben Laurie, Will Rowe]
3568 *) Fix segfaults for configuration file syntax errors such as
3569 "<Directory>" followed by "</Directory" and
3570 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
3572 *) Cleanup the --enable-layout option of configure. This makes
3573 us use a consistent location for the config.layout file, and it
3574 makes configure more portable.
3575 [jun-ichiro hagino <itojun@iijlab.net>]
3577 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
3578 csv/gnuplot format, rudimentary ssl support and various other tweaks
3579 to make results more true to what is measured. The upshot of this it
3580 turns out that 'ab' has often underreported the true performance of
3581 apache. Often by a order of magnitude :-) See talk/paper of Sander
3582 Temme at April ApacheCon 2001 for details.
3583 [Dirk-Willem van Gulik]
3585 *) Clean up mod_cgid's temporary request pool. Besides fixing a
3586 storage leak this ensures that some unnecessary pipes are closed.
3589 *) Performance: Add quick_handler hook. This hook is called at the
3590 very beginning of the request processing before location_walk,
3591 translate_name, etc. This hook is useful for URI keyed content
3592 caches like Mike Abbott's Quick Shortcut Cache.
3595 *) top_module global variable renamed to ap_top_module [Perl]
3597 *) Move ap_set_last_modified to the core. This is a potentially
3598 controversial change, because this is kind of HTTP specific. However
3599 many protocols should be able to take advantage of this kind of
3600 information. I expect that headers will need one more layer of
3601 indirection for multi-protocol work, but this is a small step in
3602 the right direction. [Ryan Bloom]
3604 *) Enable mod_status by default. This matches what Apache 1.3 does.
3607 *) Add a ScriptSock directive to the default config file. This is
3608 only enabled when mod_cgid is used.
3609 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3611 Changes with Apache 2.0.15
3613 *) Untangled the buildconf script and eliminated the need for build's
3614 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
3615 libtool muck that is now under srclib/apr/build. [Roy Fielding]
3617 *) Win32: Don't accept more connections than we have worker threads
3621 *) Fix bug in the Unix threaded.c MPM that allowed child processes
3622 to fork() new child processes.
3625 *) SECURITY: Fix a major security problem with double-reverse lookup
3626 checking. Previously, a client connecting over IPv4 would not be
3627 matched properly when the server had an IPv6 listening socket.
3628 PR #7407 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
3630 *) Change the way the beos MPM handles polling to allow it to stop and
3631 restart. Problem was the sockets being polled were being reset by
3632 the select call, so once it had accepted a connection it was no
3633 longer listening on the UDP socket we use for shutdown instructions.
3634 APR needs to be altered, patch on it's way. [David Reid]
3636 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
3637 on error exit from ap_getline(). Some other code got upset because
3638 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
3640 *) Handle ap_discard_request_body() being called more than once.
3641 [Greg Ames, Jeff Trawick]
3643 *) Get rid of an inadvertent close of file descriptor 2 in
3644 mod_mime_magic. [Greg Ames, Jeff Trawick]
3646 *) Add a hook, create_request. This hook allows modules to modify
3647 a request while it is being created. This hook is called for all
3648 request_rec's, main request, sub request, and internal redirect.
3649 When this hook is called, the the r->main, r->prev, r->next
3650 pointers have been set, so modules can determine what kind of
3651 request this is. [Ryan Bloom]
3653 *) Cleanup the build process a bit more. The Apache configure
3654 script no longer creates its own helper scripts, it just
3656 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
3658 *) Stop the forced downgrade of the connection to HTTP/1.0 for
3659 proxy requests. [Graham Leggett]
3661 *) Avoid using sscanf to determine the HTTP protocol number in
3662 the common case because sscanf is a performance hog. From
3663 Mike Abbot's Accelerating Apache patch number 6.
3664 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
3666 *) SECURITY: Fix a security exposure in mod_access. Previously when
3667 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
3668 were not evaluated properly (PR #7407). Also, add the ability to
3669 specify IPv6 address strings with optional prefix length on Allow
3670 and Deny. [Jeff Trawick]
3672 *) Enhance rotatelogs so that a UTC offset can be specified, and
3673 the logfile name can be formatted using strftime(3). (Brought
3674 forward from 1.3.) [Ken Coar]
3676 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
3677 DuplicateHandle on an IOCompletionPort (a practice which
3678 MS "discourages"). The new model does not rely on associating
3679 the completion port with the listening sockets, thus the
3680 completion port can be completely managed within the child
3681 process. A dedicated thread accepts connections off the network,
3682 then calls PostQueuedCompletionStatus() to wake up worker
3683 threads blocked on the completion port.
3686 *) Bring forward the --suexec-umask option which allows the
3687 builder to preset the umask for suexec processes. [Ken Coar]
3689 *) Add a -V flag to suexec, which causes it to display the
3690 compile-time settings with which it was built. (Only
3691 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
3693 *) Mod_include should always unset the content-length if the file is
3694 going to be passed through send_parsed_content. There is no to
3695 determine if the content will change before actually scanning the
3696 entire content. It is far safer to just remove the C-L as long
3697 as we are scanning it. [Ryan Bloom]
3699 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
3700 request and not Proxy-Authenticate.
3701 [Graham Leggett <minfrin@sharp.fm>]
3703 Changes with Apache 2.0.14
3705 *) Fix content-length computation. We ONLY compute a content-length if
3706 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
3707 or we already have all the data. [Ryan Bloom]
3709 *) Report unbounded containers in the config file. Previously, a typo
3710 in the </container> directive could result in the rest of the config
3711 file being silently ignored, with undesired defaults used.
3714 *) Make the old_write filter use the ap_f* functions for the buffering.
3717 *) Move more code from the http module into the core server. This
3718 is core code, basically the default handler, the default input
3719 and output filters, and all of the core configuration directives.
3720 All of this code is required in order for the server to work, with or
3721 without HTTP. The server is closer to working without the HTTP
3722 module, although there is still more to do. [Ryan Bloom]
3724 *) Fix a number of SGI compile warnings throughout the server. Fix some
3725 bad parameters to apr_bucket_read(). Fix a bad statement in
3726 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
3727 consistently; we were mixing apr_time_t and time_t in invalid ways
3728 before. In load_file(), call apr_dso_error() instead of
3729 apr_strerror() so that we get a more specific string on some platforms.
3730 PR #6980 [Jeff Trawick]
3732 *) Allow modules to query the MPM about it's execution profile. This
3733 query API can and should be extended in the future, but for now,
3734 max_daemons, and threading or forking is a very good start.
3735 [Jon Travis <jtravis@covalent.net>]
3737 *) Modify mod_include to send blocks of data no larger than 9k.
3738 Without this, mod_include will wait until the whole file is parsed,
3739 or the first tag is found to send any data to the client.
3740 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3742 *) Fix mod_info, so that <Directory> and <Location> directives are
3743 not displayed twice when displaying the current configuration.
3744 [Ryan Morgan <rmorgan@covalent.net>]
3746 *) Add config directives to override DEFAULT_ERROR_MSG and
3747 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
3748 [Dan Rench <drench@xnet.com>]
3750 *) Get mod_info building and loading on Win32. [William Rowe]
3752 *) Begin to move protocol independant functions out of mod_http. The goal
3753 is to have only functions that are HTTP specific in the http directory.
3756 Changes with Apache 2.0.13
3758 *) Don't assume that there will always be multiple calls to the byterange
3759 filter. It is possible that we will need to do byteranges with only
3760 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
3762 *) Move the error_bucket definition from the http module to the
3763 core server. Every protocol will need this ability, not just
3766 Changes with Apache 2.0.12
3768 *) Modify mod_file_cache to save pre-formatted strings for
3769 content-length and last-modified headers for performance.
3770 [Mike Abbot <mja@trudge.engr.sgi.com>]
3772 *) Namespace protect IOBUFSIZ since it is exposed in the API.
3773 [Jon Travis <jtravis@covalent.net>]
3775 *) Use "Basic" authentication instead of "basic" in ab, as the spec
3776 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
3778 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
3779 without ever filling it out. This fixes PR 7271.
3780 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
3781 Cliff Woolley <cliffwoolley@yahoo.com>]
3783 *) Add a couple of GCC attribute tags to printf style functions.
3784 [Jon Travis <jtravis@covalent.net>]
3786 *) Add the correct language tag for interoperation with the Taiwanese
3787 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
3789 *) Migrate the perchild MPM to use the new apr signal child, and
3790 APR thread functions. [Ryan Bloom]
3792 *) Close one copy of the CGI's stdout before creating the new process.
3793 The CGI will still have stdout, because we have already dup'ed it.
3794 This keeps Apache from waiting forever to send the results of a CGI
3795 process that has forked a long-lived child process.
3796 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3798 *) Remove the rest of the pthreads functions from the threaded MPM.
3799 This requires the APR support for a signal thread that was just
3802 *) Make mod_dir use a fixup for sending a redirect to the browser.
3803 Before this, we were using a handler, which doesn't make much
3804 sense, because the handler wasn't generating any data, it would
3805 either return a redirect error code, or DECLINED. This fits the
3806 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
3808 *) Make the threaded MPM use APR threads instead of pthreads.
3811 *) Get mod_tls to the point where it actually appears to work in all cases.
3814 *) implement --enable-modules and --enable-mods-shared for "all" and
3815 "most". [Greg Stein]
3817 *) Move the threaded MPM to use APR locks instead of pthread locks.
3820 *) Rename mpmt_pthread to threaded. This is more in line with the
3821 fact that mpmt_pthread shouldn't be using pthreads directly, and
3822 it is a smaller name that doesn't tie into anything.
3825 *) Rename the module structures so that the exported symbol matches
3826 the file name, and it is easier to automate the installation
3827 process (generating LoadModule directives from the module filenames).
3830 *) Remove the coalesce filter. With the ap_f* functions, this filter
3831 is no longer needed. [Ryan Bloom]
3833 Changes with Apache 2.0.11
3835 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
3836 added feature of allowing a uid/gid per child process. If no
3837 uid/gid is specified, then Perchild behaves exactly like dexter.
3840 *) Get perchild building again. [Ryan Bloom]
3842 *) Don't disable threads just because we are using the prefork MPM.
3843 If somebody wants to compile without threads, they must now add
3844 --disable-threads to the configure command line. [Ryan Bloom]
3846 *) Begin to move the calls to update_child_status into common code, so
3847 that each individual MPM does not need to update the scoreboard itself.
3850 *) Allow mod_tls to compile under Unix boxes where openssl has been
3851 installed to the system include files.
3852 [Gomez Henri <new-httpd@slib.fr>]
3854 *) Cleanup the mod_tls configure process. This should remove any need
3855 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
3856 configure doesn't check that yet. [Ryan Bloom]
3858 *) Add a very early prototype of SSL support (in mod_tls.c). It is
3859 vital that you read modules/tls/README before attempting to build
3862 *) Fix a potential seg fault on all platforms. David Reid fixed this
3863 on BEOS, but the problem could happen anywhere, so we don't want
3864 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
3866 *) Add new LogFormat directive, %D, to log time it takes to serve a
3867 request in microseconds. [Bill Stoddard]
3869 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
3870 SetOutputFilter. This corresponds nicely with the other Set
3871 directives, which operate on containers while the Add* directives
3872 tend to work directly on extensions. [Ryan Bloom]
3874 *) Cleanup the header handling a bit. This uses the apr_brigade_*
3875 functions for the buffering so that we don't need to compute
3876 the length of the headers before we actually create the header
3877 buffer. [Ryan Bloom]
3879 *) Allow filters to buffer data using the ap_f* functions. These have
3880 become macros that resolve directly to apr_brigade_*.
3883 *) Get the Unix MPM's to do a graceful restart again. If we are going
3884 to register a cleanup with ap_cleanup_scoreboard, then we have to
3885 kill the cleanup with the same function, and that function can't be
3886 static. [Ryan Bloom]
3888 *) Install all required header files. Without these, it was not
3889 possible to compile some modules outside of the server.
3892 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
3893 forward from 1.3 to 2.0, we missed a single line, which broke regex
3894 aliases. [Ryan Bloom]
3896 *) We have a poor abstraction in the protocol. This is a temporary
3897 hack to fix the bug, but it will need to be fixed for real. If
3898 we find an error while sending out a custom error response, we back
3899 up to the first non-OK request and send the data. Then, when we send
3900 the EOS from finalize_request_protocol, we go to the last request,
3901 to ensure that we aren't sending an EOS to a request that has already
3902 received one. Because the data is sent on a different request than
3903 the EOS, the error text never gets sent down the filter stack. This
3904 fixes the problem by finding the last request, and sending the data
3905 with that request. [Ryan Bloom]
3907 *) Make the server status page show the correct restart time, and
3908 thus the proper uptime. [Ryan Bloom]
3910 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
3911 should reduce the amount of duplicate code that is required to
3912 create CGI processes.
3913 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3915 *) ap_new_connection() closes the socket and returns NULL if a socket
3916 call fails. Usually this is due to a connection which has been
3917 reset. [Jeff Trawick]
3919 *) Move the Apache version information out of httpd.h and into release.h.
3920 This is in preparation for the first tag with the new tag and release
3921 system. [Ryan Bloom]
3923 *) Begin restructuring scoreboard code to enable adding back in
3924 the ability to use IPC other than shared memory.
3925 Get mod_status working on Windows again. [Bill Stoddard]
3927 *) Make mod_status work with 2.0. This will work for prefork,
3928 mpmt_pthread, and dexter. [Ryan Bloom]
3930 *) Correct a typo in httpd.conf.
3931 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
3933 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
3935 *) Get the correct IP address if ServerName isn't set and we can't
3936 find a fully-qualified domain name at startup.
3937 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
3939 *) Make mod_cgid work with SuExec. [Ryan Bloom]
3941 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
3942 'extra' stat's for user/group since they should never occur, and now
3943 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
3944 volumes. [William Rowe]
3946 *) Adopt apr features to simplify mod_includes. This changes the
3947 behavior of the USER_NAME variable, unknown uid's are now reported
3948 as USER_NAME="<unknown>" rather than the old user#000 result.
3949 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
3951 *) Adopt apr features for simplifing mod_userdir, and accept the new
3952 Win32/OS2 exceptions without hiccuping. [William Rowe]
3954 *) Replace configure --with-optim option by using and saving the
3955 environment variable OPTIM instead. This is needed because configure
3956 options do not support multiple flags separated by spaces.
3959 *) Fix some byterange handling. If we get a byte range that looks like
3960 "-999999" where that is past the end of the file, we should return
3961 a PARTIAL CONTENT status code, and return the whole file as one big
3962 byterange. This matches the 1.3 handling now. [Ryan Bloom]
3964 *) Make the error bucket a real meta-data bucket. This means that the
3965 bucket length is 0, and a read returns NULL data. If one of these
3966 buckets is passed down after the headers are sent, this data will
3967 just be ignored. [Greg Stein]
3969 *) The prefork MPM wasn't killing child processes correctly if a restart
3970 signal was received while the process was serving a request. The child
3971 process would become the equivalent of a second parent process. If
3972 we break out of the accept loop, then we need to do die after cleaning
3973 up after ourselves. [Ryan Bloom]
3975 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
3976 restarts. [Ryan Bloom]
3978 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
3979 the most optimal APR_FINFO_wanted bits. This spares Win32 from
3980 performing very expensive owner, group and permission lookups
3981 and allows the server to function until these apr_finfo_t fields
3982 are implemented under Win32. [William Rowe]
3984 *) Support for typedsafe optional functions - that is functions exported by
3985 optional modules, which, therefore, may or may not be present, depending
3986 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
3987 for sample code. [Ben Laurie]
3989 *) filters can now report an HTTP error to the server. This is done
3990 by sending a brigade where the first bucket is an error_bucket.
3991 This bucket is a simple bucket that stores an HTTP error and
3992 a string. Currently the string is not used, but it may be needed
3993 to output an error log. The http_header_filter will find this
3994 bucket, and output the error text, and then return
3995 AP_FILTER_ERROR, which informs the server that the error web page
3996 has already been sent. [Ryan Bloom]
3998 *) If we get an error, then we should remove all filters except for
3999 those critical to serving a web page. This fixes a bug, where
4000 error pages were going through the byterange filter, even though
4001 that made no sense. [Ryan Bloom]
4003 *) Relax the syntax checking of Host: headers in order to support
4004 iDNS. PR#6635 [Tony Finch]
4006 *) Cleanup the byterange filter to use the apr_brigade_partition
4007 and apr_bucket_copy functions. This removes a lot of very messy
4008 code, and hopefully makes this filter more stable.
4011 *) Remove AddModule and ClearModuleList directives. Both of these
4012 directives were used to ensure that modules could be enabled
4013 in the correct order. That requirement is now gone, because
4014 we use hooks to ensure that modules are in the correct order.
4017 *) When SuExec is specified, we need to add it to the list of
4018 targets to be built. If we don't, then any changes to the
4019 configuration won't affect SuExec, unless 'make suexec' is
4020 specifically run. [Ryan Bloom]
4022 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4023 the APR_XTHREAD argument to open a file for consumption by
4024 parallel threads on win32. [William Rowe]
4026 *) Correct a bug in determining when we follow symlinks. The code
4027 expected a stat -1 result, not an apr_status_t positive error.
4028 Also check if the APR_FINFO_USER fields are valid before we
4029 follow the link. [William Rowe]
4031 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4032 mpm_common.c. These functions are only valid on some platforms,
4033 so they should not be in the main-line code. [Ryan Bloom]
4035 *) Remove ap_chdir_file(). This function is not thread-safe,
4036 and nobody is currently using it. [Ryan Bloom]
4038 *) Do not try to run make depend if there are no .c files in the
4039 current directory, doing so makes `make depend` fail.
4042 *) Update highperformance.conf to work with either prefork or
4043 pthreads mpms. [Greg Ames]
4045 *) Stop checking to see if this is a pipelined request if we know
4046 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4047 This keeps us from making an extra read call when serving a 1.0
4048 request. [Ryan Bloom and Greg Stein]
4050 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4051 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4052 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4054 *) Fix the RFC number mentioned when complaining about a missing
4055 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
4057 *) Fix an endless loop in ab which occurred when ab was posting
4058 and the server dropped the connection unexpectedly.
4061 *) Fix a segfault while handling request bodies in ap_http_filter().
4062 This problem has been seen with mod_dav usage as well as with
4063 requests where the body was just being discarded. [Jeff Trawick]
4065 *) Some adjustment on the handling and automatic setting (via
4066 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4067 add the capability to specify flags (NOTEST_CFLAGS and
4068 NOTEST_LDFLAGS) which are used to compile Apache, but
4069 not used during the configuration process. Useful for
4070 flags like "-Werror". [Jim Jagielski]
4072 *) Stop using environment variables to force debug mode or
4073 no detach. We now use the -D command line argument to
4074 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4075 [Greg Stein, Ryan Bloom]
4077 *) Change handlers to use hooks. [Ben Laurie]
4079 *) Stop returning copies of filenames from both apr_file_t and
4080 apr_dir_t. We pstrdup the filenames that we store in the
4081 actual structures, so we don't need to pstrdup the strings again.
4084 *) mod_cgi: Fix some problems where the wrong error value was being
4085 traced. [Jeff Trawick]
4087 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
4090 *) Add generic hooks. [Ben Laurie]
4092 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
4094 *) Fix a segfault caused by mod_ext_filter when the external filter
4095 program does not exist. [Jeff Trawick]
4097 *) Fix an output truncation error when on an HTTP >= 1.0 request an
4098 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
4099 was served through mod_charset_lite (or anything else that would
4100 create a transient bucket in this size range). ap_bucket_make_heap()
4101 silently failed (fixed), transient_setaside() discovered it, but
4102 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
4104 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
4105 is that some browsers send extra lines at the end of POST requests, and
4106 we don't want to delay sending data back to the user just because the
4107 browser isn't well behaved. [Ryan Bloom]
4109 *) Get SuEXEC working again. We can't send absolute paths to suExec
4110 because it refuses to execute those programs. SuEXEC also wasn't
4111 always recognizing configuration changes made using the autoconf
4114 *) Allow the buildconf process to find the config.m4 files in the correct
4115 order. Basically, we can now name config.m4 files as config\d\d.m4,
4116 and we will sort them correctly when inserting them into the build
4117 process. [Ryan Bloom]
4119 *) Get mod_cgid to use apr calls for creating the actual CGI process.
4120 This also allows mod_cgid to use ap_os_create_priviledged_process,
4121 thus allowing for SuExec execution from mod_cgid. Currently, we do
4122 not support everything that standard SuExec supports, but at least
4123 it works minimally now. [Ryan Bloom]
4125 *) Allow SuExec to be configured from the ./configure command line.
4128 *) Update some of the docs in README and INSTALL to reflect some of
4129 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
4131 *) If we get EAGAIN returned from the call to apr_sendfile, then we
4132 need to call sendfile again. This gets us serving large files
4133 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
4135 *) Get the support programs building cleanly again.
4136 [Cliff Woolley <cliffwoolley@yahoo.com>]
4138 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
4139 current directory logic now backs up over bin/ to determine the
4140 server root from the Apache.exe path.
4142 *) Apache/Win32 now follows the standard conventions of mod_foo.so
4143 loadable modules, dynamic libs are all named libfoo.dll, and the
4144 makefile.win populates the include, lib and libexec directories.
4146 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
4147 Apache gets IPv6 listening sockets by default. Additionally, the
4148 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
4149 numeric address strings (e.g., "Listen [fe80::1]:8080").
4152 *) Modify the install directory layout. Modules are now installed in
4153 modules/. Shared libraries should be installed in libraries/, but
4154 we don't have any of those on Unix yet. All install directories
4155 are modifyable at configure time. [Ryan Bloom]
4157 *) Install all header files in the same directory on Unix. [Ryan Bloom]
4159 *) Get the functions in server/linked into the server, regardless of
4160 which modules linked into the server. This uses the same hack
4161 for Apache that we use for APR and apr-util to ensure all of the
4162 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
4163 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
4164 the scripts a bit easier.
4167 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
4168 on the query, and remove IPv4 dependencies. [Jeff Trawick]
4170 *) Get all of the auth modules to the point that they will install and
4171 be loadable into the server. Our new build/install mechanism expects
4172 that all modules will have a common name format. The auth modules
4173 didn't use that format, so we didn't install them properly.
4176 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
4177 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
4179 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
4181 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
4182 after the end of the response. [Ryan Bloom]
4184 *) Get byterange requests working with responses that do not have a
4185 content-length. Because of the way byterange requests work, we have to
4186 have all of the data before we can actually do the byterange, so we
4187 can compute the content-length in the byterange filter.
4190 *) Get exe CGI's working again on Windows.
4193 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
4194 they keep track of whether or not their post config hook has been
4195 called before. Instead of a static variable (which is replaced when
4196 the DSO is loaded a second time), use userdata in the process pool.
4199 Changes with Apache 2.0a9
4201 *) Win32 now requires perl to complete the final install step for users
4202 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
4203 and installs the conf, htdocs and htdocs/manual directories.
4206 *) Make mod_include use a hash table to associate directive tags with
4207 functions. This allows modules to implement their own SSI tags easily.
4208 The idea is simple enough, a module can insert it's own tag and function
4209 combination into a hash table provided by mod_include. While mod_include
4210 parses an SSI file, when it encounters a tag in the file, it does a
4211 hash lookup to find the function that implements that tag, and passes
4212 all of the relevant data to the function. That function is then
4213 responsible for processing the tag and handing the remaining data back
4214 to mod_include for further processing.
4215 [Paul J. Reder <rederpj@raleigh.ibm.com>]
4217 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
4218 fewer parameters: the local and remote socket addresses were removed
4219 from the parameter list because all required information is available
4220 via the APR socket. [Jeff Trawick]
4222 *) Distribution directory structure reorganized to reflect a
4223 normal source distribution with external install targets.
4226 *) The MPMs that need multiple segments of shared memory now create
4227 two apr_shmem_t variables, one for each shared memory allocation.
4228 the problem is that we can't determine how much memory will be required
4229 for shared memory allocations once we try to allocate more than one
4230 variable. The MM code automatically aligns the shared memory allocations,
4231 so we end up needing to pad the amount of shared memory we want based
4232 on how many variables will be allocated out of the shared memory segment.
4233 It is just easier to create a second apr_shmem_t variable, and two
4234 shmem memory blocks.
4237 *) Cleanup the export list a bit. This creates a single unified list of
4238 functions exported by APR. The export list is generated at configure
4239 time, and that list is then used to generate the exports.c file.
4240 Because of the way the export list is generated, we only export those
4241 functions that are valid on the platform we are building on.
4244 *) Enable logging the cookie with mod_log_config
4245 [Sander van Zoest <sander@covalent.net>]
4247 *) Fix a segfault in mod_info when it reaches the end of the configuration.
4250 *) Added lib/aputil/ as a placeholder for utility functions which are not
4251 specific to the Apache HTTP Server (but do not make sense with APR).
4252 The first utility is "apu_dbm": a set of functions to work with DBM
4253 files. This first version can be compiled for SDBM or GDBM databases.
4256 *) Complete re-write of mod_include. This makes mod_include a filter that
4257 uses buckets directly. This has now served the FAQ correctly.
4258 [Paul Reder <rederpj@raleigh.ibm.com>]
4260 *) Allow modules to specify the first filter in a sub_request when
4261 making the sub_request. This keeps modules from having to change the
4262 output_filter immediately after creating the sub-request, and therefore
4263 skip the sub_req_output_filter. [Ryan Bloom]
4265 *) Update ab to accept URLs with IPv6 literal address strings (in the
4266 format described in RFC 2732), and to build Host header fields in
4267 the same format. This allows IPv6 literal address strings to be
4268 used with ab. This support has been tested against Apache 1.3 with
4269 the KAME patch, but Apache 2.0 does not yet work with this format
4270 of the Host header field. [Jeff Trawick]
4272 *) Accomodate an out-of-space condition in the piped logs and the
4273 rotatelogs.c code, and no longer churn log processes for this
4274 condition. [Victor J. Orlikowski]
4276 *) Add support for partial writes with apr_sendfile() to core_output_filter.
4279 Changes with Apache 2.0a8
4281 *) Add a directive to mod_mime so that filters can be associated with
4285 *) Get multi-views working again. We were setting the path_info
4286 field incorrectly if we couldn't find the specified file.
4289 *) Fix 304 processing. The core should never try to send the headers
4290 down the filter stack. Always, just setup the table in the request
4291 record, and let the header filter convert it to data that is ready
4295 *) More fixes for the proxy. There are still bugs in the proxy code,
4296 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
4300 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
4303 *) APR: Add new apr_getopt_long function to handle long options.
4304 [B. W. Fitzpatrick <fitz@red-bean.com>]
4306 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
4307 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
4308 hostname resolution/address string parsing and building
4309 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
4310 of one of the apr_sockaddr_t structures for a socket. Change
4311 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
4313 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
4314 I have proxied pages with it, cleanup will commence soon.
4317 *) Make the proxy work with filters. This isn't perfect, because we
4318 aren't dealing with the headers properly. [Ryan Bloom]
4320 *) Do not send a content-length iff the C-L is 0 and this is a head
4321 request. [Ryan Bloom]
4323 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
4324 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
4326 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
4328 *) Get the default_handler to stop trying to deal with HEAD requests.
4329 The idea is to let the content-length filter compute the C-L before
4330 we try to send the data. If we can get the C-L correctly, then we
4331 should send it in the HEAD response.
4334 *) The Header filter can now determine if a body should be sent based
4335 on r->header_only. The general idea of this is that if we delay
4336 deciding to send the body, then we might be able to compute the
4337 content-length correctly, which will help caching proxies to cache
4338 our data better. Any handler that doesn't want to try to compute
4339 the content-length can just send an EOS bucket without data and
4340 everything will just work.
4343 *) Add the referer to the error log if one is available.
4344 [Markus Gyger <mgyger@itr.ch>]
4346 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
4347 change, the root of the configuration tree has been exposed to modules
4349 [Ryan Morgan <rmorgan@covalent.net>]
4351 *) Get the core_output_filter to use the bucket interface directly.
4352 This keeps us from calling the content-length filter multiple times
4353 for a simple static request.
4356 *) We are sending the content-type correctly now.
4357 [Ryan Bloom and Will Rowe]
4359 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
4360 a bogus bytes-sent value when the only thing being sent was trailers
4361 and writev() returned an error (or EAGAIN). [Jeff Trawick]
4363 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
4364 hints file to determine which platforms define
4365 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
4368 *) APR: add apr_get_home_directory() [Jeff Trawick]
4370 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
4372 *) Not all platforms have INADDR_NONE defined by default. Apache
4373 used to make this check and define INADDR_NONE if appropriate,
4374 but APR needs the check too, and I suspect other applications will
4375 as well. APR now defines APR_INADDR_NONE, which is always a valid
4376 value on all platforms.
4377 [Branko Èibej <brane@xbc.nu>]
4379 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
4380 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
4382 *) Relax the syntax checking of Host: headers in order to support
4383 iDNS. PR#6635 [Tony Finch]
4385 *) When reading from file buckets we convert to an MMAP if it makes
4386 sense. This also simplifies the default handler because the
4387 default handler no longer needs to try to create MMAPs.
4390 *) BUFF has been removed from the main server. The BUFF code will remain
4391 in the code until it has been purged from the proxy module as well.
4394 *) Byteranges have been completely re-written to be a filter. This
4395 has been tested, and I believe it is working correctly, but it could
4396 doesn't work for the Adobe Acrobat plug-in. The output almost matches
4397 the output from 1.3, the only difference being that 1.3 includes
4398 a content-length in the response, and this does not.
4401 *) APR read/write functions and bucket read functions now operate
4402 on unsigned integers, instead of signed ones. It doesn't make
4403 any sense to use signed ints, because we return the error codes,
4404 so if we have an error we should report 0 bytes read or written.
4407 *) Always compute the content length, whether it is sent or not.
4408 The reason for this, is that it allows us to correctly report
4409 the bytes_sent when logging the request. This also simplifies
4410 content-length filter a bit, and fixes the actual byte-reporing
4411 code in mod_log_config.c
4414 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
4415 it says, because it was only used by EOS and FLUSH buckets. Since
4416 neither of those are required at the end of a brigade, this was
4417 really signifying FLUSH_THE_DATA, but that can be determined better
4418 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
4419 buckets now return a length of 0, which is actually the amount of data
4420 read, so they make more sense.
4423 *) Allow the core_output_filter to save some data past the end of a
4424 request. If we get an EOS bucket, we only send the data if it
4425 makes sense to send it. This allows us to pipeline request
4426 responses. As a part of this, we also need to allocate mmap
4427 buckets out of the connection pool, not the request pool. This
4428 allows the mmap to outlive the request.
4431 *) Make blocking and non-blocking bucket reads work correctly for
4432 sockets and pipes. These are the only bucket types that should
4433 have non-blocking reads, because the other bucket types should
4434 ALWAYS be able to return something immediately.
4437 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
4438 server, but use Ctrl+Break to initiate a graceful restart
4439 instead of duplicating behavior. [John Sterling]
4441 *) Patch mod_autoindex to set the Last-Modified header based on
4442 the directory's mtime, and add the ETag header. [William Rowe]
4444 *) Merge the 1.3 patch to add support for logging query string in
4445 such a way that "%m %U%q %H" is the same as "%r".
4448 *) Port three log methods from mod_log_config 1.3 to 2.0:
4449 CLF compliant '-' byte count, method and protocol.
4452 *) Add a new LogFormat directive, %c, that will log connection
4453 status at the end of the response as follows:
4454 'X' - connection aborted before the response completed.
4455 '+' - connection may be kept-alive by the server.
4456 '-' - connection will be closed by the server.
4459 *) Expand APR for WinNT to fully accept and return utf-8 encoded
4460 Unicode file names and paths for Win32, and tag the Content-Type
4461 from mod_autoindex to reflect that charset if the the feature
4462 macro APR_HAS_UNICODE_FS is true. [William Rowe]
4464 *) Compute the content length (and add appropriate header field) for
4465 the response when no content length is available and we can't use
4466 chunked encoding. [Jeff Trawick]
4468 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
4469 so that content input filters get dechunked data when using
4470 the default handler. Also removed REQUEST_CHUNKED_PASS.
4473 *) Add mod_ext_filter as an experimental module. This module allows
4474 the administrator to use external programs as filters. Currently,
4475 only filtering of output is supported. [Jeff Trawick]
4477 *) Most Apache functions work on EBCDIC machines again, as protocol
4478 data is now translated (again). [Jeff Trawick]
4480 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
4481 the EBCDIC support. They are noops on ASCII machines, so this
4482 type of translation doesn't have to be surrounded by #ifdef
4483 CHARSET_EBCDIC. [Jeff Trawick]
4485 *) Fix mod_include. tag commands work again, and the server will
4486 send the FAQ again. This also allows mod_include to set aside
4487 buckets that include partial buckets.
4488 [Ryan Bloom and David Reid]
4490 *) Add suexec support back. [Manoj Kasichainula]
4492 *) Lingering close now uses the socket directly instead of using
4493 BUFF. This has been tested, but since all we can tell is that it
4494 doesn't fail, this needs to be really hacked on.
4497 *) Allow filters to modify headers and have those headers be sent to
4498 the client. The idea is that we have an http_header filter that
4499 actually sends the headers to the network. This removes the need
4500 for the BUFF to send headers.
4503 *) Charset translation: mod_charset_lite handles translation of
4504 request bodies. Get rid of the xlate version of ap_md5_digest()
4505 since we don't compute digests of filtered (e.g., translated)
4506 response bodies this way anymore. (Note that we don't do it at
4507 all at the present; somebody needs to write a filter to do so.)
4510 *) Input filters and ap_get_brigade() now have a input mode parameter
4511 (blocking, non-blocking, peek) instead of a length parameter.
4514 *) Update the mime.types file to the registered media types as
4515 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
4518 *) Namespace protect some macros declared in ap_config.h
4521 *) Support HTTP header line folding with input filtering.
4524 *) Mod_include works again. This should still be re-written, but at
4525 least now we can serve an SHTML page again.
4528 *) Begin to remove BUFF from the core. Currently, we keep a pointer
4529 to both the BUFF and the socket in the conn_rec. Functions that
4530 want to use the BUFF can, functions that want to use the socket,
4531 can. They point to the same place.
4534 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
4535 [Tomas "Ögren" <stric@ing.umu.se>]
4537 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
4538 associated pool goes away. (APR pipes on OS/2 were already had this
4539 logic.) This resolvs a fatal file descriptor leak with CGIs.
4542 *) The final line of the config file was not being read if there was
4543 no \n at the end of it. This was caused by apr_fgets returning
4544 APR_EOF even though we had read valid data. This is solved by
4545 making cfg_getline check the buff that was returned from apr_fgets.
4546 If apr_fgets return APR_EOF, but there was data in the buf, then we
4547 return the buf, otherwise we return NULL.
4550 *) Piped logs work again in the 2.0 series.
4553 *) Restore functionality broken by the mod_rewrite security fix:
4554 rewrite map lookup keys and default values are now expanded
4555 so that the lookup can depend on the requested URI etc.
4556 PR #6671 [Tony Finch]
4558 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
4559 security bug in some mass virtual hosting configurations
4560 that can allow a remote attacker to retrieve some files
4561 on the system that should be inaccessible. [Tony Finch]
4563 *) Add a pool bucket type. This bucket is used for data allocated out
4564 of a pool. If the pool is cleaned before the bucket is destroyed, then
4565 the data is converted to a heap bucket, allowing it to survive the
4569 *) Add a flush bucket. This allows modules to signal that the filters
4570 should all flush whatever data they currently have. There is no way
4571 to actually force them to do this, so if a filter ignores this bucket,
4572 that's life, but at least we can try with this.
4575 *) Add an output filter for sub-requests. This filter just strips the
4576 EOS bucket so that we don't confuse the main request's core output
4577 filter by sending multiple EOS buckets. This change also makes sub
4578 requests start to send EOS buckets when they are finished.
4581 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
4582 makes ap_bucket_destroy a return void, which is okay because it
4583 used to always return APR_SUCCESS, and nobody ever checked its
4584 return value anyway.
4585 [Cliff Woolley <cliffwoolley@yahoo.com>]
4587 *) Remove the index into the bucket-type table from the buckets
4588 structure. This has now been replaced with a pointer to the
4589 bucket_type. Also add some macros to test the bucket-type.
4592 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
4593 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
4594 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
4595 All _VAR_ flavors changes to _DATA to be absolutely clear.
4598 *) Add support for /, //, //servername and //server/sharename
4599 parsing of <Directory> blocks under Win32 and OS2.
4600 [Tim Costello, William Rowe, Brian Harvard]
4602 *) Remove the function pointers from the ap_bucket type. They have been
4603 replaced with a global table. Modules are allowed to register bucket
4604 types and use then use those buckets.
4607 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
4608 once we finish writing the request body to the cgi child process;
4609 otherwise, the client doesn't hit EOF on stdin. Small request bodies
4610 worked without this change (for reasons I don't understand), but large
4611 ones didn't. [Jeff Trawick]
4613 *) Remove file bucket specific information from the ap_bucket type.
4614 This has been moved to a file_bucket specific type that hangs off
4615 the data pointer in the ap_bucket type.
4618 *) Input filtering now has a third argument. This is the amount of data
4619 to read from lower filters. This argument can be -1, 0, or a positive
4620 number. -1 means give me all the data you have, I'll deal with it and
4621 let you know if I need more. 0 means give me one line and one line
4622 only. A positive number means I want no more than this much data.
4624 Currently, only 0 and a positive number are implemented. This allows
4625 us to remove the remaining field from the conn_rec structure, which
4629 *) Big cleanup of the input filtering. The goal is that http_filter
4630 understands two conditions, headers and body. It knows where it is
4631 based on c->remaining. If c->remaining is 0, then we are in headers,
4632 and http_filter returns a line at a time. If it is not 0, then we are
4633 in body, and http_filter returns raw data, but only up to c->remaining
4634 bytes. It can return less, but never more.
4635 [Greg Ames, Ryan Bloom, Jeff Trawick]
4637 *) mod_cgi: Write all of the request body to the child, not just what
4638 the kernel would accept on the first write. [Jeff Trawick]
4640 *) Back out the change that moved the brigade from the core_output_filters
4641 ctx to the conn_rec. Since all requests over a given connection
4642 go through the same core_output_filter, the ctx pointer has the
4646 *) Fix another bug in the send_the_file() read/write loop. A partial
4647 send by apr_send would cause unsent data in the read buffer to
4648 get clobbered. Complete making send_the_file handle partial
4649 writes to the network.
4652 *) Fix a couple of type fixes to allow compilation on AIX again
4653 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
4655 *) Fix bug in send_the_file() which causes offset to be ignored
4656 if there are no headers to send.
4659 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
4660 filter. Useful for supporting Windows 9* with a binary
4661 compiled on Windows NT.
4664 Changes with Apache 2.0a7
4666 *) Reimplement core_output_filter to buffer/save bucket brigades
4667 across multiple calls to the core_filter. The brigade will be
4668 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
4669 thresholds are hit or the EOS bucket is received.
4672 *) Create experimental filter (buffer_filter) that coalesces bytes
4673 into one large buffer before invoking the next filter in the
4674 chain. This filter is particularly useful with the current
4675 implementation of mod_autoindex when it inserted above the
4676 chunk_filter. mod_autoindex generates a lot of brigades that
4677 containing buckets holding just a few bytes each. The
4678 buffer_filter coalesces these buckets into a single large bucket.
4681 *) Add apr_sendfile() support into the core_output_filter.
4684 *) Add apr_sendv() support into the core_output_filter.
4687 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
4688 [Mike Abbott <mja@sgi.com>]
4690 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
4691 make much sense, because Apache uses buckets instead of BUFFs now.
4694 *) send_the_file now falls back to a read/write loop on platforms that
4695 do not have sendfile.
4696 [Ryan Bloom and Brian Havard]
4698 *) Install apachectl correctly, and substitute the proper values so
4699 that it works again. [Ryan Bloom]
4701 *) Better(??) handle platforms that lack sendfile().
4704 *) APR now has UUID generation/formatting/parsing support.
4707 *) Begin the http_filter. This is an input filter that understands
4708 the absolute basic amount required to parse an HTTP Request. The
4709 goal is to be able to split headers from request body before passing
4710 the data back to the other filters.
4713 *) Bring forward from 1.3.13 the config directory implementation
4716 *) install apxs if it is created
4719 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
4720 conversions. [William Rowe]
4722 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
4723 ap_add_output_filter(). [Jeff Trawick]
4725 *) Multiple build and configuration fixes
4728 -add datadir and localstatedir substitutions
4730 -fix logfilename misspelling
4731 -fix evaluation of installation dir variables and
4732 -replace $foobar by $(foobar) to be usefull in the makefile
4736 -add rules for cross-compiling in rules.mk. Okay, rule to check for
4737 $CC_FOR_BUILD is still missing
4738 -use CHECK_TOOL instead of CHECK_PROG for ranlib
4739 -add missing "AR=@AR@" to severaly Makefile.in's
4740 -cache result for "struct rlimit"
4741 -compile all helper programs with native and cross compiler
4742 and use the native version to generate header file
4743 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
4745 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
4747 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
4749 *) Fix a bug where a client which only sends \n to delimit header
4750 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
4751 message. Start working on ebcdic co-existance with input
4753 [William Rowe, Greg Ames]
4755 *) If mod_so is enabled in the server always create libexec, even
4756 if there are no modules installed in this directory. This is a
4757 requirement for APXS to work correctly.
4760 *) Connection oriented output filters are now stored in the
4761 conn_rec instead of the request_rec. This allows us to add the
4762 output filter in the pre-connection phase instead of the
4763 post_read_request phase, which keeps us from trying to write an
4764 error page before we have a filter to write to the network.
4765 [Ryan Bloom, Jeff Trawick, and Greg Ames]
4767 *) Cleaning up an mmap bucket no longer deletes the mmap. An
4768 mmap can be used across multiple buckets (default_handler with
4769 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
4770 the mmap itself can't be associated with the bucket.
4773 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
4776 *) Radical surgery to improve mod_isapi support under Win32.
4777 Includes a number of newer ServerSupportFunction calls, support
4778 for ReadClient (in order to retrieve POSTs greater than 48KB),
4779 and general bug fixes to more reliably load ISAPI .dll's and
4780 prevent leaking handle resources. Note: There are still
4781 discrepancies between IIS's and Apache's ServerVariables, and
4782 async calls are still not supported. Additional warnings are
4783 logged to facilitate debugging of unsupported ISAPI calls.
4786 *) Add input filtering to Apache. The basic idea for the input
4787 filters is the same as the ideas for output filters. The biggest
4788 difference is that instead of calling ap_pass_brigade, ap_get_brigade
4789 should be called, and the order of execution for the filter itself is
4790 different. When writing an output filter, a brigade is passed in,
4791 and filters operate directly on that brigade, when done, they call
4792 ap_pass_brigade. Input filters are the exact opposite. Because input
4793 is not a push operation, filters first call ap_get_brigade. When this
4794 function returns, the input filter will be left with a valid brigade.
4795 The input filter should then operate on the brigade, and return.
4798 *) Fix building on BSD/OS using its native make. The build system
4799 falls back to the BSD .include directive on that host platform.
4802 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
4803 SHA1 and plaintext password encodings. Make feature tests a
4804 bit more flexible. [William Rowe]
4806 *) Charset translation: mod_charset_lite handles output content
4807 translation in a filter. mod_charset_lite no longer ignores
4808 subrequests. A bunch of cruft related to BUFF's support for
4809 translating request and response bodies was removed.
4812 *) Move the addition of the CORE filter to the post_read_request
4813 hook in http_core.c. This removes the need to add the filter in
4814 multiple places and allows for an SSL module to be added much
4815 simpler. [Ryan Bloom]
4817 *) SECURITY: CVE-2000-0913 (cve.mitre.org)
4818 Fix a security problem that affects certain configurations of
4819 mod_rewrite. If the result of a RewriteRule is a filename that
4820 contains expansion specifiers, especially regexp backreferences
4821 $0..$9 and %0..%9, then it may be possible for an attacker to
4822 access any file on the web server. [Tony Finch]
4824 *) Fix a bug where errors that are detected during early request parsing
4825 don't produce visible HTTP error messages at the browser, because
4826 the core_filter wasn't present. [Greg Ames]
4828 *) Provide apr_socklen_t as a portability aid.
4829 [Victor J. Orlikowski]
4831 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
4832 as well as a comment arg to the add, adduser and update cmds.
4833 update allows the user to clear or preserve pw/groups/comment.
4834 Fixed a bug in dbmmanage that prevented the check option from
4835 parsing a password followed by :group... text. Corrected the
4836 seed calcualation for Win32 systems, and added -lsdbm support.
4839 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
4842 *) Avoid a segfault when parsing .htaccess files. An
4843 uninitialized tree pointer was passed to ap_build_config().
4846 *) Change the way that inet_addr & inet_network are checked for
4847 in APR's configure process to allow BeOS BONE to correctly
4848 find them. With this change BeOS BONE now builds from source
4849 with no problems. [David Reid]
4851 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
4852 the end of the parameters to execve() was stored in the wrong
4853 location, overlaying the storage beyond the newargs[] array and
4854 also passing uninitialized storage to execve(), which would
4855 sometimes fail with EFAULT. [Jeff Trawick]
4857 *) Fix a bug parsing configuration file containers. With a sequence
4858 like this in the config file
4860 <IfModule mod_kilroy.c>
4863 <IfModule mod_lovejoy.c>
4868 the second container would be terminated at the blank line due to
4869 sediment in the buffer from reading the prior </IfModule> and an
4870 error message would be generated for the real </IfModule> for the
4871 second container. Also due to this problem, any two characters
4872 could be used for "</" in the close of a container.
4875 *) ap_add_filter prototype changed to remove the ctx pointer. The
4876 pointer still remains in the filter structure, but it can not be
4877 a part of the ap_add_filter prototype. The reason is that when
4878 the core uses AddFilter to add a filter to the stack it doesn't
4879 know how to allocate the ctx pointer, or even how much memory should
4880 be allocated. The filters will have to be responsible for allocating
4881 the ctx memory when they need it.
4884 *) Add an AddFilter directive. This directive takes a list of filters
4885 that should be activated for the requested resource.
4888 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
4889 some other platforms). [Jeff Trawick]
4891 *) Modify mod_include to be a filter. Currently, it has only been tested
4892 on actual files, but it should work for CGI scripts too.
4895 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
4896 writes. apr_flush() for Unix: handle interrupted writes.
4899 *) NameVirtualHost can now take "*" as an argument instead of
4900 an IP address. This allows you to create a purely name-based
4901 virtual hosting server that does not have any IP addresses in
4902 the configuration file and which ignores the local address
4903 of any connections. PR #5595, PR #4455 [Tony Finch]
4905 *) Fix some compile warnings in mod_mmap_static.c
4906 [Mike Abbott <mja@sgi.com>]
4908 *) Fix chunking problem with CGI scripts. The general problem was that
4909 the CGI modules were adding an EOS bucket and then the core added an
4910 EOS bucket. The chunking filter finalizes the chunked response when it
4911 encounters an EOS bucket. Because two EOS buckets were sent, we
4912 finalized the response twice. The fix is to make sure we only send one
4913 EOS, by utilizing a flag in the request_rec.
4916 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
4917 and Win32. Previously, the first read from an apr_file_t set up via
4918 apr_put_os_file() would return a '\0'. [Jeff Trawick]
4920 *) Mod_cgid now creates a single element bucket brigade, with a pipe
4921 bucket, instead of using BUFF's and ap_r*.
4924 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
4925 [Mike Abbott <mja@sgi.com>]
4927 *) Remove ap_bopenf from buff code. This required modifying the file_cache
4928 code to use APR file's directly instead of going through BUFFs.
4931 *) Fix compile break on some platforms for mod_mime_magic.c
4932 [John K. Sterling <sterling@covalent.net>]
4934 *) Fix merging of AddDefaultCharset directive.
4935 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
4937 *) Minor revamp of the rlimit sections of code. We now test
4938 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
4939 is now "available" even if the platform doesn't support
4940 the rlimit family (it's just a noop though). [Jim Jagielski]
4942 *) Migrate the pre-selection of which MPM to use for specific
4943 platforms to hints.m4, which contains (or should contain)
4944 all platform specific "hints". [Jim Jagielski]
4946 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
4949 *) Add tables with non-string/binary values to APR.
4952 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
4955 *) Update PCRE to version 3.2. [Ryan Bloom]
4957 *) Change the way buckets' destroy functions are called so that
4958 they can be more directly used when changing the type of a
4959 bucket in place. [Tony Finch]
4961 *) Add generic support for reference-counting the resources used by
4962 buckets, and alter the HEAP and MMAP buckets to use it. Change
4963 the way buckets are initialised to support changing the type of
4964 buckets in place, and use it when setting aside TRANSIENT buckets.
4965 Change the implementation of TRANSIENT buckets so that it can be
4966 mostly shared with IMMORTAL buckets, which are now implemented.
4969 Changes with Apache 2.0a6
4971 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
4973 *) Add a chunking filter to Apache. This brings us one step closer
4974 to removing BUFF. [Ryan Bloom]
4976 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
4977 added to the stack is the last filter to be called. [Ryan Bloom]
4979 *) Apache 2.0 has been completely documented using Scandoc. The
4980 docs can be generated by running 'make docs'. [Ryan Bloom]
4982 *) Add filtered I/O to Apache. This is based on bucket brigades,
4983 Currently the buckets still use BUFF under the covers, but that
4984 should change quickly. The only currently written filter is the
4985 core filter which just calls ap_bwrite. [The Apache Group]
4987 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
4988 built with thread support. [Jeff Trawick]
4990 *) Abort configuration if --with-layout was specified and there's
4991 no layout definition file. [Ken Coar]
4993 *) Add support for '--with-port=n' option to configure. [Ken Coar]
4995 *) Add support for extension methods for the Allow response header
4996 field, and an API routine for accessing r->allowed and the
4997 list of extension methods in a unified manner. [Ken Coar]
4999 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5000 [Rob Simonson <simo@us.ibm.com>]
5002 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5003 APACHE_XLATE builds. [Jeff Trawick]
5005 *) A configuration file parsing problem was fixed. When the
5006 configuration file started with an IfModule/IfDefine container,
5007 only the last statement in the container would be retained.
5010 Changes with Apache 2.0a5
5012 *) Perchild is serving pages after passing them to different child
5013 processes. There are still a lot of bugs, but this does work. I
5014 have made requests against the same installation of Apache, and had
5015 different servers use different user IDs to serve the responses.
5016 This change moves to using socketpair instead of an AF_UNIX socket.
5019 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5020 It can't seem to pass between child processes yet, but I think we
5021 are closer now than before. This moves us back to using Unix
5022 Domain Sockets. [Ryan Bloom]
5024 *) libapr functions and types renamed with apr_ prefix.
5025 #include "apr_compat.h" for 1.3.x backwards compat
5028 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5029 return the right information on the local socket address.
5030 [Gregory Nicholls <gnicholls@level8.com>]
5032 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5033 [Gregory Nicholls <gnicholls@level8.com>]
5035 *) Add an option to not detach from the controlling terminal without
5036 going into single process mode. This allows for much easier
5037 debugging of the process startup code. [Ryan Bloom]
5039 *) ab: don't use perror() to report the failure of an APR function.
5042 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5043 scoreboard on graceful restarts.
5046 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5047 An invalid ap_proc_t was passed to ap_create_process().
5050 *) Allow modules to register filters. Those filters are still
5051 never called, but this is a step in the right direction.
5052 [Ryan Bloom and Greg Stein]
5054 *) Register the mod_cgid daemon process for cleanup so that it is
5055 killed at termination if it does not die when the parent gets
5056 SIGTERM. This change is to fix occasional problems where the
5057 process stays around. Bugs in similar logic in mod_rewrite and
5058 mod_include were also fixed. [Jeff Trawick]
5060 *) Fix a bug in the time handling. Basically, we were imploding a time
5061 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5062 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5063 uses those two fields to adjust the time value. Because of the HTTP
5064 spec, both of those values can be zero'ed out safely. This fixes
5065 the bug correctly. [Ryan Bloom]
5067 *) Fix a couple of place in the Windows code where the wrong error
5068 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
5070 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5072 *) Added the APR_EOL_STR macro for platform dependent differences in
5073 logfiles and other raw text (such as all APR files). Fixes logfiles
5074 not terminated with cr/lf sequences in Win32. [William Rowe]
5076 *) Move all strings functions in APR to src/lib/apr/strings and create
5077 apr_strings.h for the prototypes. [Ryan Bloom]
5079 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5080 to repeat the syscall until we stop getting EINTR. I noticed a
5081 related problem at termination (SIGTERM) on FreeBSD when using
5082 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5083 implementation work properly with child init. Previously, ap_lock()
5084 was essentially a no-op because all children were using different
5085 locks and thus nobody ever blocked. [Jeff Trawick]
5087 *) The htdocs/ tree has been moved out of the CVS source tree into
5088 a separate area for easier development. This has NO EFFECT on
5089 end-users or Apache installations. [Ken Coar]
5091 *) Integrate the mod_dav module for WebDAV protocol handling. This
5092 adds the dav and dav_fs modules, the SDBM library, and additional
5093 XML handling utilities. [Greg Stein]
5095 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
5098 *) Update the lib/expat-lite/ library (bring forward changes from
5099 the Apache 1.3 repository). [Greg Stein]
5101 *) If sizeof(long long) == sizeof(long), then prefer long in APR
5102 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
5104 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
5105 machines where sendfile is detected, but nobody has written ap_sendfile.
5106 [Dave Hill <ddhill@zk3.dec.com>]
5108 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
5110 *) ab would start up more connections than needed, then quit when the
5111 desired number were finished. Also fixed a logic error involving
5112 ab keepalives. [Victor J. Orlikowski]
5114 *) WinNT: Implement non-blocking pipes with timeouts to communicate
5115 with CGIs. Apache 2.0a4 had non-blocking pipes but without
5116 timeouts (i.e, if a timeout was specified, the pipe reverted to
5117 a full blocking pipe). Now the behaviour is more in line with
5118 Unix non-blocking pipes.
5121 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
5122 cache open file handles along with accept socket reuse enables
5123 Apache 2.0 to serve non-keepalive requests for static files at
5124 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
5125 and Apache 2.0 will serve almost 1200 rps on my system).
5128 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
5129 supports two config directives, mmapfile (same behavious as
5130 mod_mmap_static) and cachefile. Use the cachefile directive
5131 to cache open file handles. This directive only works on systems
5132 that have implemented the ap_sendfile API. cachefile works today
5133 on Windows NT, but has not been tested on any flavors of Unix.
5136 *) Cleanup the configuration. With the last few changes the
5137 configuration process automatically:
5138 inherits information about how to build from APR. Allowing
5139 APR to inform Apache that it should or should not use -ldl
5141 Detects which mod_cgi should be used mod_cgi or mod_cgid,
5142 based on the threading model
5144 Apache calls APR's configure process before finishing it's
5145 configuration processing, allowing for more information flow
5150 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
5151 with non-zero argument makes the socket non-blocking. BeOS and
5152 OS/2 already worked this way. [Jeff Trawick]
5154 *) ap_close() now calls ap_flush() for buffered files, so write
5155 operations work a whole lot better on buffered files.
5158 *) Fix error messages issued from MPMs which explain where to change
5159 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
5162 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
5163 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
5164 now the way that the blocking state of a pipe is manipulated.
5165 ap_block_pipe() is gone. [Jeff Trawick]
5167 *) Correct the problem where the only local host name that the IP stack
5168 can discover are 'undotted' private names. If no fully qualified
5169 domain name can be identified, the default ServerName will be set to
5170 the machine's IP address string. A warning is always provided if the
5171 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
5173 *) Repair problems with config file processing which caused segfault
5174 at init when virtual hosts were defined and which caused ServerName to
5175 be ignored when there was no valid DNS setup. [Jeff Trawick]
5177 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
5179 *) Add ap_sendfile implementation for AIX
5180 [Victor J. Orlikowski]
5182 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
5183 apr_network_io.h, and apr_thread_proc.h.
5184 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
5186 *) Bring the allocation and pool debugging code back into a working
5187 state. This will need to be tested as so far it's only been used on
5190 *) Change configuration command setup to be properly typesafe when in
5191 maintainer mode. Note that this requires a compiler that can initialise
5192 unions. [Ben Laurie]
5194 *) Turn on buffering for config file reads. Part of this was to
5195 repair buffered I/O support in Unix and implement buffered
5196 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
5198 *) Win32: Fix problem where UTC offset was not being set correctly
5199 in the access log. Problem reported on news group by Jerry Baker.
5202 *) Fix segfault when reporting this type of syntax error:
5203 "</container> without matching <container> section", where
5204 container is VirtualHost or Directory or whatever.
5207 *) SECURITY: CAN-2000-1204 (cve.mitre.org)
5208 Prevent the source code for CGIs from being revealed when
5209 using mod_vhost_alias and the CGI directory is under the document root
5210 and a user makes a request like http://www.example.com//cgi-bin/cgi
5211 as reported in <news:960999105.344321@ernani.logica.co.uk>
5214 *) Add support for the new Beos NetwOrking Environment (BONE)
5217 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
5218 final input char is incomplete; ap_bwrite_xlate() now handles
5219 incomplete final input chars. [Jeff Trawick]
5221 *) Yet another update to saferead/halfduplex stuff -- need to ensure
5222 that a bhalfduplex call occurs before logging or else DNS and
5223 such can delay the last packet of the response. [Dean Gaudet]
5225 *) Some syscall reduction in APR on unix -- don't seek when setting
5226 up an mmap; and don't fcntl() more than once per socket.
5229 *) When mod_cgid is started as root, the cgi daemon now switches
5230 to the configured User/Group (like other httpd processes)
5231 instead of continuing as root. [Jeff Trawick]
5233 *) The prefork MPM now uses an APR lock for the accept() mutex.
5234 It has not been getting a lock at all recently. httpd -V now
5235 displays APR's selection of the lock mechanism instead of the
5236 symbols previously respected by prefork. [Jeff Trawick]
5238 *) Change the mmap() feature test to check only for existence.
5239 The previous check required features not used by Apache.
5242 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
5243 sometimes mangled. The len parm to accept() was not
5244 initialized, leading sometimes to an endless loop of failed
5245 accept() calls on OS/390 and anywhere else that failed the call
5246 if the len was negative. Use <sys/un.h> for struct sockaddr_un
5247 instead of declaring it ourselves to fix a compilation problem
5248 on Solaris. [Jeff Trawick]
5250 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
5252 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
5254 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
5256 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
5257 initialization if ALLOC_DEBUG is defined; no known symptom
5258 otherwise. [Jeff Trawick]
5260 *) Fix typo in configure script when checking for mod_so. bash
5261 doesn't seem to have a problem but /bin/sh on Solaris does.
5262 Symptom: "./configure: test: unknown operator =="
5265 *) Rebind the Win32 NT and 9x services control into the MPM.
5266 All console, WinNT SCM and Win9x pseudo-service control code is
5267 now wrapped within the WinNT MPM.
5270 *) Make a copy of getenv("PATH") before storing for later use. Some
5271 getenv() implementations use the same storage for successive calls.
5272 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
5274 *) Server Tokens work in 2.0 again. This also propogates the change
5275 to allow just the product name in the server string using
5279 Changes with Apache 2.0a4
5281 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
5282 won't need to call it. [Greg Ames, Jeff Trawick]
5284 *) Move pre_config hook call to between configuration read and config
5285 tree walk. This allows all modules to implement pre_config hooks
5286 and know that they will be called at an appropriate time.
5289 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
5292 *) Add pre-config hooks back to all modules.
5295 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
5296 ContentDigest enabled and we can't/don't mmap the file.
5299 *) We now report the correct line number for syntax errors in config
5300 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
5302 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
5303 related bugs, and changed shmem/locking to use apr API. Shared-mem
5304 is currently disabled, however, because of problems with graceful
5305 restarts. [Ronald Tschalär]
5307 *) Fix corruption of IFS variable in --with-module= handling.
5308 Depending on the user's shell or customization thereof, there
5309 would be errors generating ap_config_auto.h later in the configure
5310 procedure. [Jeff Trawick]
5312 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
5313 isn't used (as in 1.3), except that on Unix it is now logged via
5314 ap_log_rerror() instead of by the child having STDERR_FILENO refer
5315 to the error log. [Greg Ames, Jeff Trawick]
5317 *) Add '-D' argument processing for run time configuration defines.
5320 *) Organize http_main.c as independent code, such that no code or
5321 global data is exported from it. WIN32 will dynamically link it
5322 to the server core, so this will prevent mutual dependency.
5325 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
5326 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
5329 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
5330 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
5332 *) Add mod_charset_lite for configuring character set translation.
5335 *) Add '-n' option to htpasswd to make it print its user:pw record
5336 on stdout rather than having to frob a text file. [Ken Coar]
5338 *) Fix saferead. Basically, we flush the output buffer if a read on the
5342 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
5343 a conversion is single-byte only. [Jeff Trawick]
5345 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
5346 the BeOS 5.0 documentation says that shutdown doesn't work yet.
5349 *) Fix some minor errors where pid was being manipulated as an int
5350 instead of the portable pid_t. [Roy Fielding]
5352 *) Fix some error log prints that were printing the pointer to a
5353 structure rather than the pid within the structure.
5354 [Jeff Trawick, Roy Fielding]
5356 *) ab: Fix a command-line processing bug; track bad headers in
5357 err_response; support reading headers up to 2K.
5358 [Ask Bjoern Hansen <ask@valueclick.com>]
5360 *) Fix ap_resolve_env() so that it handles new function added in a prior
5361 alpha (see "Added the capability to do ${ENVVAR} constructs in the
5362 config file.") as well as the constructs used by mod_rewrite.
5363 [Paul Reder <rederpj@raleigh.ibm.com>]
5365 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
5367 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
5368 APR to perform translation, instead of accessing the hard-coded tables
5369 in 1.3's ebcdic.c. [Jeff Trawick]
5371 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
5374 *) Add the ability to hook into the config file reading phase. Basically
5375 if a directive is specified EXEC_ON_READ, then when that directive is
5376 read from the config file, the assocaited function is executed. This
5377 should only be used for those directives that must muck with HOW the
5378 server INTERPRETS the config. This should not be used for directives
5379 that re-order or replace items in the config tree. Those changes should
5380 be made in the pre-config step.
5383 *) Add mod_example to the build system.
5386 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
5387 byte character sets. [Jeff Trawick]
5389 *) Pick up various EBCDIC fixes from 1.3 (from Martin
5390 Kraemer and Oliver Reh originally according to the change log).
5393 *) Fix a couple of problems in RFC1413 support (controlled by the
5394 IdentityCheck directive). Apache did not build the request string
5395 properly and more importantly Apache would loop forever if the
5396 would-be ident server dropped the connection before sending a
5397 properly terminated response. [Jeff Trawick]
5399 *) apxs works in 2.0.
5402 *) Reliable piped logs work in 2.0.
5405 *) Introduce a hash table implementation into APR to be used for
5406 replacing tables and other random data structures in Apache.
5409 *) Add some more error reporting to htpasswd in the case of problems
5410 generating or accessing the temporary file. Also, pass in a
5411 buffer if the implementation knows how to use it (i.e., if L_tmpnam
5412 is defined). [Ken Coar]
5414 *) Configure creates config.nice now containing your configure
5415 options. Syntax: ./config.nice [--more-options]
5418 *) Fix various return code problems in APR on Win32. For most of
5419 these, APR was returning APR_EEXIST instead of GetLastError()/
5420 WSAGetLastError(). [Jeff Trawick]
5422 *) Make piped logs work again in version 2.0
5425 *) Add VPATH support to UNIX build system of Apache and APR.
5428 *) Fix ap_tokenize_to_argv to respect the const arguments that are
5432 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
5433 Patch submitted to author.
5436 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
5437 /sbin in PATH on FreeBSD (all submitted to rse previously)
5440 *) Fix building Pthread-based MPMs on OpenBSD
5441 [Sascha Schumann] PR#26
5443 *) Fix ap_readdir() problem on systems where d_name[] field in
5444 struct dirent is declared with only one byte. (This problem only
5445 affected multithreaded builds.) This caused a segfault during
5446 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
5447 least). [Jeff Trawick]
5449 *) Fix some make-portability problems on at least Tru64, Irix
5451 [Sascha Schumann] PR#18, PR#39
5453 *) Add ap_sigwait() to support old-style sigwait() on systems
5454 like OS/390 and UnixWare.
5457 *) Add POSIX-thread flags for more platforms.
5460 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
5461 (on Unix, at least) to handle resolver errors. Fix a bug in
5462 the definition of APR_ENOMEM so that ap_strerror() can spit
5463 out the correct error message for it.
5466 Changes with Apache 2.0a3
5468 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
5471 *) API: *HOOK* macros now have an AP_ prefix
5474 *) Win32: Eliminate redundant calls to initialize winsock.
5475 [Tim Costello <timcostello@ozemail.com.au>]
5477 *) Fix bugs initializing ungetchar for pipes.
5478 [Chia-liang Kao <clkao@CirX.ORG>]
5480 *) The ab program in the src/support directory is now portable using
5484 *) Support directory is being compiled when the server is built
5487 *) The configure option --with-program-name has been added to allow
5488 developers to rename the executable at configure time. This also
5489 changes the name of the config files to match the executable's name.
5492 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
5493 containing version numbers. [Martin Pool]
5495 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
5496 Unix; access_log and error_log now created with these perms; non-
5497 Unix is unaffected [Jeff Trawick]
5499 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
5500 Replaced more magic numbers with MD5_DIGESTSIZE.
5501 [William Rowe, Roy Fielding]
5503 *) Win32: Get mod_auth_digest compiling and added to the Windows
5504 build environment. Not tested and I'd be suprised if it
5505 actually works. [Bill Stoddard]
5507 *) Revamp the Win32 make environment. Makefiles have been removed and
5508 Apache.dsw created to bring together all the pieces. Create new file
5509 os/win32/BaseAddr.ref to define module base addresses (to prevent
5510 dll relocation at start-up).
5511 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
5513 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
5514 of the \015, \012, and \015\012 constants with macros.
5517 *) Add ap_xlate_open() et al for translation of text between different
5518 character sets. The initial implementation requires iconv().
5521 *) More FAQs and answers from comp.infosystems.www.servers.unix.
5522 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5524 *) CGI output is being timed out now.
5527 *) Fix the problem with dieing quietly. dupfile now takes a pool which
5528 is used by the new apr file. There is no reason to create a new file
5529 with the same lifetime as the original file.
5532 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
5533 module base addresses. This will help shooting seg faults
5534 in the field. [William Rowe <wrowe@lnd.com>]
5536 *) Update Apache on Windows documentation. Add new document
5537 describing how to compile Apache on Windows.
5538 [William Rowe <wrowe@lnd.com>]
5540 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
5541 microseconds instead of seconds. Some storage leaks and other
5542 minor bugs in related code were fixed. [Jeff Trawick]
5544 *) Win32: First cut at getting mod_isapi working under 2.0
5545 [William Rowe <wrowe@lnd.com>]
5547 *) First stab at getting mod_auth_digest working under 2.0
5548 quick change summary:
5549 - moved the random byte generation (ap_generate_random_bytes) into APR
5550 - now uses ap_time_t
5551 - compiles and runs on linux
5553 [Brian Martin <bmartin@penguincomputing.com>]
5555 *) Win32: Move the space stripping of physical service names
5556 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
5557 unresolved symbol. Add dependency checking to the
5558 CreateService call to ensure TCPIP and AFP (winsock) is started
5560 [William Rowe <wrowe@lnd.com>]
5562 *) Win32: Add code to perform latebinding on functions that may
5563 not exist on all levels of Windows where Apache runs. This
5564 is needed to allow Apache to start-up on Win95/98. All calls
5565 to non portable functions should be protected with
5566 ap_oslevel checks to prevent runtime segfaults.
5567 [William Rowe <wrowe@lnd.com>]
5569 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
5571 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
5573 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
5574 This addresses PR 1623. Still need to address timing out runaway
5575 CGI scripts. [Bill Stoddard]
5577 *) Win32: Make ap_stat Windows 95/98 friendly
5578 [William Rowe <wrowe@lnd.com>]
5580 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
5581 always fail. Need to initialise the dwOSVersionInfoSize member of the
5582 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
5585 The patch also enhances ap_get_oslevel (and the associated enum) to
5586 handle selected service packs for NT4, and adds recognition for
5587 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
5588 we can use ReadFileScatter and WriteFileGather in readwrite.c.
5589 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
5591 *) Get mod_rewrite building and running, and mod_status building for Win NT
5592 [Allan Edwards <ake@raleigh.ibm.com>]
5594 *) Patch to port mod_auth_db to the 2.0 api and also to support
5595 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
5596 2.7.7. It should work with version 1 as well but I haven't tested it.
5597 [Brian Martin <bmartin@penguincomputing.com>]
5599 *) Get APR DSO code working under Windows. Includes cross platform
5601 [Tim.Costello@BTFinancialgroup.com]
5603 *) Fix some of the Windows APR time functions.
5606 *) FAQ changes related to tidying up historical documents on the web site.
5607 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5609 *) Move Windows DSO code into APR.
5612 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
5613 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
5614 at build time. At this point, the server will not compile on Windows because
5615 of the recent DSO commits. Fixing those next.
5616 [Bill Rowe & Bill Stoddard]
5618 *) Added error checking for file I/O APR routines.
5619 [Jon Travis <jtravis@covalent.net>]
5621 *) APR: Don't use the values of resolver error codes for the
5622 corresponding APR error codes. On Unix and Win32, return the
5623 proper APR error code after a resolver error. [Jeff Trawick]
5625 Changes with Apache 2.0a2
5627 *) Renamed the executable back to httpd on all platforms other
5631 *) Allow BeOS to survive restarts, log properly and a few
5632 small things it had problems with due to the way it setup
5633 users and groups. [David Reid]
5635 *) Get mod_rewrite working with APR locks
5636 [Paul Reder <rederpj@raleigh.ibm.com>]
5638 *) Actually remove the sempahore when the lock cleanup routine
5639 is called on BeOS. [David Reid]
5641 *) Clear hook registrations between reads of the config file.
5642 When DSOs are unloaded and re-loaded the old hook pointers may
5643 no longer be valid. This fix eliminates potential segfaults.
5644 [Allan Edwards <ake@raleigh.ibm.com>]
5646 *) Fix a problem with Sigfunc not being defined or bypassed
5647 if sigaction() wasn't found. [Jim Jagielski]
5649 *) Fix the locking mechanism on BSD variants. They now use fcntl
5650 locks. This allows the server to start and serve pages.
5653 *) First cut at getting the Win32 installer to work
5654 [William Rowe <wrowe@lnd.com>]
5656 *) Get htpasswd compiling under Windows
5657 [William Rowe <wrowe@lnd.com>]
5659 *) Change the log message for a bind() failure to show the
5660 interface and port number. [Jeff Trawick]
5662 *) Import the documentation from 1.3.12 and bring parts of it
5663 up-to-date with respect to the changes that have occurred
5667 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
5668 now logged correctly on BeOS.
5671 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
5672 Makefile.win includes the same user interface as the old
5674 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
5676 *) Win32 exec now uses COMSPEC environment string for command

5678 [William Rowe <wrowe@lnd.com>] PR#3715
5680 *) Win32: ap_connect() was not returning correct error condition
5682 [Allen Prescott <allen@clanprescott.com>]
5684 *) Win32: ap_open() was broken on Win9x because an NT-specific
5685 flag was passed to CreateFile. ap_puts() added an unnecessary
5687 [Jeff Trawick <trawick@us.ibm.com>]
5689 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
5690 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
5691 confusing ee/et name and made all extensions language/dialect
5692 rather than country reflecting. Changed example files to
5693 explicit reflect the ISO charset and added a few common
5694 ones to the example config [dirkx]
5696 *) Extend external module capability. To use this, you call
5697 configure with --with-module=path/to/mod1,path/to/mod2,etc.
5700 *) Backported the various "default charset" fixes from 1.3.12,
5701 including the AddDefaultCharset directive. [Jim Jagielski]
5703 *) Added the capability to do ${ENVVAR} constructs in the
5704 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
5705 it does this on a line by line basis; i.e. if the envvar
5706 expands to something with spaces you have to protect it
5707 by adding quotes around it (Unless of course you expect it
5708 to contains more than one argument. Alternatively you
5709 can compile it on a per token basis; which is what people
5710 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
5711 hampers fancier hacks.
5712 [Dirk-Willem van Gulik]
5714 *) Changed the 'ErrorDocument' syntax in that it NO longer
5715 supports the asymetric
5717 ErrorDocument 301 "Some message
5719 Note the opening " quote, without a closing quote. It now
5720 has either the following syntaxes
5722 ErrorDocument XXX /local/uri
5723 ErrorDocument XXX http://valid/url
5724 ErrorDocument XXX "Some Message"
5726 The recognition heuristic is: if it has a space it
5727 is a message. If it has no spaces and starts with a /
5728 or is a valid URL then treat it that way. Otherwise it
5729 is assumed to be a message.
5731 This breaks backward compatibility but makes live a hell
5732 of a lot easier for GUI's and config file parsers.
5733 [Dirk-Willem van Gulik]
5735 *) Changed 'CacheNegotiatedDocs' from its present/not-present
5736 syntax into a 'on' or 'off' syntax. As it currently is the
5737 only non nesting token which uses NO_ARGS and thus is an
5738 absolute pain for any config interface automation. This
5739 breaks backward compatibility. [Dirk-Willem van Gulik]
5741 *) Add ability to add external modules to the build process. This is
5742 done with --with-module=/path/to/module. Modules can only be added
5743 as static modules at this point.
5746 Changes with Apache 2.0a1
5748 *) Fix FreeBSD 3.3 core dump.
5749 Basically, ap_initialize() needs to get called before
5750 create_process(), since create_process() passes op_on structure
5751 to semop() to get a lock, but op_on isn't initialized until
5752 ap_initialize() calls setup_lock(). Here is a slight
5753 rearrangement to main() which calls ap_initialize() earlier...
5754 [Jeff Trawick <trawick@us.ibm.com>]
5756 *) Enable Apache to use sendfile/TransmitFile API
5757 [Bill Stoddard, David Reid, Paul Reder]
5759 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
5763 *) Make file I/O and network I/O writev/sendv APIs consistent.
5764 Eliminate use of ap_iovec_t and use Posix struct iovec.
5765 Use seperate variable on ap_writev to set the number of iovecs
5766 passed in and number of bytes written.
5769 *) Adapt file iol to use APR functions. Replaced ap_open_file()
5770 with ap_create_file_iol(). ap_create_file_iol() requires that
5771 the file be opened prior to the call using ap_open().
5774 *) Port mod_include and mod_cgi to 2.0
5775 [Paul Reder, Bill Stoddard]
5777 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
5778 bytes_read/bytes_written is always valid (never -1). Plus
5779 some fixes to buff.c to correct problems introduced by the
5780 errno => ap_status_t changes a while back. Plus a fix to
5781 chunked encoding introduced right at the beginning of 2.0.
5784 *) Revamped UNIX build system to use autoconf and libtool.
5785 [Manoj Kasichainula, Sascha Schumann]
5787 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
5789 *) SECURITY: More rigorous checking of Host: headers to fix security
5790 problems with mass name-based virtual hosting (whether using mod_rewrite
5791 or mod_vhost_alias).
5792 [Ben Hyde, Tony Finch]
5794 *) Add back support for UseCanonicalName in <Directory> containers.
5795 [Manoj Kasichainula]
5797 *) Added APLOG_STARTUP log type. This allows us to write an error
5798 message without any of the date and time information. As a part
5799 of this change, I also removed all of the calls to fprintf(stderr
5800 and replaced them with calls to ap_log_error using APLOG_STARTUP
5801 writing to stderr is no longer portable, because we don't direct
5802 stderr to the error log on all platforms.
5805 *) Convert error logging functions to take errno as an argument.
5806 This makes our error logs more portable, because some Windows API's
5807 don't set errno. This change allows us to still output a valid
5808 message on all of our platforms.
5811 *) mod_mime_magic runs in 2.0-dev now.
5812 [Paul Reder <rederpj@raleigh.ibm.com>]
5814 *) sendfile has been added to APR.
5815 [John Zedlewski <zedlwski@Princeton.EDU>]
5817 *) buff.c has been converted to no longer use errno.
5818 [Manoj Kasichainula]
5820 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
5821 interface adaption to APR functions did it. [Martin Kraemer]
5823 *) Support DSOs properly on 32-bit HP-UX 11.0
5824 [Dilip Khandekar <dilip@cup.hp.com>]
5826 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
5827 [Ralf S. Engelschall]
5829 *) Cleaned APR build environment integration and bootstrap APR
5830 automatically for developers from src/Configure.
5831 [Ralf S. Engelschall]
5833 *) Fixed building of src/support/htpasswd.c
5834 [Ralf S. Engelschall]
5836 *) When generating the Location: header, mod_speling forgot
5837 to escape the spelling-fixed uri. (Forw-Port from 1.3)
5840 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
5842 *) Change all pools to APR contexts. This is the first step to
5843 incorporating APR into Apache. [Ryan Bloom]
5845 *) Move "handler not found" warning message to below the check
5846 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
5847 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
5849 *) Support line-continuation feature in config.option file and
5850 allow the loading of multiple option sections at once via
5851 ``--with-option=<section1>,<section2>,...''
5852 [Ralf S. Engelschall]
5854 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
5856 Changes with Apache MPM
5858 *) Use asynchronous AcceptEx() and a completion port to accept and
5859 dispatch connections to threads in Windows NT/2000.
5862 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
5865 *) Implement the APACI --with-option facility
5866 (per default used the config.option file).
5867 [Ralf S. Engelschall]
5869 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
5871 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
5872 Replace pre_connection module call with a register_hook call and
5873 implement pre_connection as a hook. The intent is that these hooks will
5874 be extended to allow Apache to be multi-protocol, and also to allow the
5875 calling order to be specified on a per-hook/per-module basis.
5878 *) Implement mpm_* methods as "modules". Each method gets its own
5879 subdir in src/modules (eg: src/modules/prefork). Selection
5880 of method uses Rule MPM_METHOD. [Jim Jagielski]
5882 *) Port the hybrid server from the apache-apr repository as
5883 mpm_mpmt_pthread. [Manoj Kasichainula]
5885 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
5886 amongst the unix MPMs.
5888 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
5889 signal handling for the new world order. [Dean Gaudet]
5891 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
5892 of alloc.c for now. [Dean Gaudet]
5894 *) Handle partial large writes correctly. [Ben Laurie]
5896 *) Eliminate conn_rec's pointer to server. All it knows is the base server
5897 based on IP/port. [Ben Laurie]
5899 *) Port a bunch of modules to the new module structure.
5900 ["Michael H. Voase" <mvoase@midcoast.com.au>]
5902 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
5904 *) Basic restructuring to introduce the MPM concept; includes various
5905 changes to the module API... better described by
5906 docs/initial_blurb.txt. [Dean Gaudet]
5908 Changes with Apache pthreads
5910 *) New buff option added: BO_TIMEOUT. It describes the timeout for
5911 buff operations (generally over a network).
5912 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
5914 *) Created http_accept abstraction. Added 4 new functions (not exported):
5915 init_accept(), begin_accepting_requests(), get_request(),
5916 stop_accepting_requests() [Bill Stoddard]
5918 *) Fix to ap_rprintf call that allows mod_info to work properly.
5919 [James Morris <jmorris@intercode.com.au>]
5921 *) user and ap_auth_type fields were moved from connection_rec to
5922 request_rec. [Ryan Bloom]
5924 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
5925 needed in a threaded server.
5927 *) Initial pthread implementation from from Dean's apache-nspr code.
5928 [Bill Stoddard, Ryan Bloom]
5931 Changes with Apache 1.3.9
5933 *) Remove bogus error message when a redirect doesn't set Location.
5934 Instead, use an empty string to avoid coredump if the error message
5935 was supposed to include a location. [Roy Fielding]
5937 *) Don't allow configure to include mod_auth_digest unless it is
5938 explicitly requested, even if the user asked for all modules.
5941 *) Translate module names to dll names for OS/2 so that they are no more
5942 than 8 characters long and have an extension of "dll" instead of "so".
5945 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
5946 Fix test-compile check to check for randbyte instead of trand32.
5947 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
5948 and tweak to make Amaya happier. [Ronald Tschalär]
5950 *) Ensure that the installed expat include files are world readable,
5951 just like the other header files. [Martin Kraemer]
5953 *) Fixed generated AddModule adjustments in APACI's `configure' script
5954 in order to allow (new) modules like mod_vhost_alias to be handled
5955 correctly (which was touched by the adjustments for mod_alias).
5956 [Ralf S. Engelschall]
5958 *) For binary builds, add -R flag to apachectl to work around the lack of
5959 an absolute path to the ./libexec directory where the libhttp.ep file
5960 is needed for SHARED_CORE architectures. [Randy Terbush]
5962 *) WIN32: Create the CGI script process as DETACHED. This may solve the
5963 problem observed by some Win95/98 users where they get CGI script
5964 output sent to the console. [Bill Stoddard]
5966 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
5967 routines are now called ap_base64* and are 'plain' (i.e., no
5968 pool access or anything clever). Inside util.c the routines acting
5969 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
5970 The oddly named ap_uuencode(), ap_uudecode() are kept around for
5971 now but deprecated. [dirkx]
5973 *) Clean up the base64 and SHA1 additions and make sure they are
5974 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
5975 files. [Roy Fielding]
5977 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
5978 checking. Allow compiling on VS 6.0. [Randy Terbush]
5980 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
5982 *) Use TestCompile to search for the truerand library (rather than blindly
5983 assuming its existence). If it is not found, complain (but do not
5984 exit - yet). [Martin Kraemer]
5986 *) We forgot to add the new exported function names to
5987 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
5989 *) Add description of -T command-line option to usage().
5990 [Ralf S. Engelschall]
5992 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
5993 searched only AFTER libap has been searched, because libap needs
5994 some symbols from libos. [Martin Kraemer]
5996 *) Fix conflict with original mod_digest related to the symbol of the
5997 module dispatch list (which has to be unique for DSO and follow the
5998 usual conventions for the installation procedure).
5999 [Ralf S. Engelschall]
6001 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6002 for other platforms as well. [Martin Kraemer]
6004 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6005 types by AP_LONG and replace reference to renamed variable 'ubuf'
6006 by 'buffer'. [Martin Kraemer]
6008 Changes with Apache 1.3.8 [not released]
6010 *) Flush the output buffer immediately after sending an error or redirect
6011 response, since the result may be needed by the client to abort a
6012 long data transfer or restart a series of pipelined requests.
6013 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
6015 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6016 [Ian Turner <iant@sequent.com>] PR#4735
6018 *) Local struct mmap in http_core.c conflicted with system structure
6019 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6021 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6022 [Ronald Tschalär <ronald@innovation.ch>]
6024 *) Fix a memory leak where the module counts were getting messed
6025 up across restarts. [David Harris <dharris@drh.net>]
6027 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6028 properly in mod_access.
6029 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
6031 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6032 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
6034 *) PORT: Support for compaq/tandem/com.
6035 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
6037 *) Added SHA1 password encryption support to easy migration from
6038 Netscape servers. See support/SHA1 for more information.
6039 Caused the separation of ap_md5.c into md5, sha1 and a general
6040 ap_checkpass.c with just a validate_passwd routine. Added a
6041 couple of flags to support/htpasswd. Some reuse of the to64()
6042 function; hence renamed to ap_to64().
6043 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
6045 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6046 with ASCII/EBCDIC conversions in "ident" query.
6047 [David McCreedy <McCreedy@us.ibm.com>]
6049 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6050 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6051 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6053 *) Fix SIGSEGV on some systems because the Vary fix below included
6054 a call to table_do with a variable argument list that was not
6055 NULL terminated. Replaced with better implementation. [Roy Fielding]
6057 Changes with Apache 1.3.7 [not released]
6059 *) The "Vary" response header field is now sanitised right before
6060 the header is sent back to the client. Multiple "Vary" fields
6061 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6062 "Vary: host, negotiate, host, accept-language") are reduced to
6063 single instances. This is a better solution than the force-no-vary
6064 one (which is still valid for clients that can't cope with Vary
6065 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6067 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
6069 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6070 least on Linux and FreeBSD for now.
6073 *) Win32: More apache -k restart work. Restarts are now honored
6074 immediately and connections in the listen queue are -not- lost.
6075 This is made possible by the use of the WSADuplicateSocket()
6076 call. The listeners are opened in the parent, duplicated, then
6077 the duplicates are passed to the child. The original listen sockets
6078 are not closed by the parent across a restart, thus the listen queue
6080 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6082 *) Fix handling of case when a client has sent "Expect: 100-continue"
6083 and we are going to respond with an error, but get stuck waiting to
6084 discard the body in the pointless hope of preserving the connection.
6085 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
6087 *) Fix 'configure' to work correctly with SysV-based versions of
6088 'tr' (consistent with Configure's use as well). [Jim Jagielski]
6090 *) apxs: Add "-S var=val" option which allows for override of CFG_*
6091 built-in values. Add "-e" option which works like -i but doesn't
6092 install the DSO; useful for editing httpd.conf with apxs. Fix
6093 editing code so that multiple invocations of apxs -a will not
6094 create duplicate LoadModule/AddModule entries; apxs can now be
6095 used to re- enable/disable a module. [Wilfredo Sanchez]
6097 *) Win32: Update the server to use Winsock 2. Specifically, link with
6098 ws2_32.lib rather than wsock32.lib. This gives us access to
6099 WSADuplcateSocket() in addition to some other enhanced comm APIs.
6100 Win 95 users may need to update their TCP/IP stack to pick up
6101 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
6102 [Bill Stoddard stoddard@raleigh.ibm.com]
6104 *) Win32: Redirect CGI script stderr (script debug info) into the
6105 error.log when CGI scripts fail. This makes Apache on Win32
6106 behave more like Unix.
6107 [Bill Stoddard stoddard@raleigh.ibm.com]
6109 *) Fixed `httpd' usage display: -D was missing.
6110 [Ralf S. Engelschall] PR#4614
6112 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
6113 [Ralf S. Engelschall] PR#4561, PR#4562
6115 *) OS/2: Fix problem with accept lock semaphores where server would die with
6116 "OS2SEM: Error 105 getting accept lock. Exiting!"
6117 [Brian Havard] PR#4505
6119 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
6120 [Randy Terbush <randy@covalent.net>]
6122 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
6123 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
6125 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
6126 command potentially _is_ GCC. [Ralf S. Engelschall]
6128 *) Fix apxs build issues on AIX
6129 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
6131 *) DocumentRoot Checking: Under previous versions, when Apache
6132 first started up, it used to do a stat of each DocumentRoot to
6133 see if it existed and was a directory. If not, then an error
6134 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
6135 does not exist, you will get error messages in error_log. If
6136 the '-t' command line option is used (to check the configuration)
6137 the check of DocumentRoot IS performed. An additional command
6138 line option, '-T', has been added if you want to avoid the
6139 DocumentRoot check even when checking the configuration.
6142 *) Win32: The query switch "apache -S" didn't exit after showing the
6143 vhost settings. That was inconsistent with the other query functions.
6144 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
6146 *) Win32: Changed behaviour of apache -k restart.
6147 Previously, the server would drain all connections in the stack's
6148 listen queue before honoring the restart. On a busy server, this
6149 could take hours. Now, a restart is honored almost immediately.
6150 All connections in Apache's queues are handled but connections in
6151 the stack's listen queue are discarded. Restart triggered by
6152 MaxRequestPerChild is unchanged.
6153 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6155 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
6156 the accept loop. Good for a 5% performance boost. Cleaned up
6157 parent/child process management code.
6158 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6160 *) Added ceiling on file size for memory mapped files.
6161 [John Giannandrea <jg@meer.net>] PR#4122
6163 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
6164 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
6165 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
6167 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
6168 use this at least for Expat. [Ralf S. Engelschall]
6170 *) Allow .module files to specify libraries with Lib:.
6173 *) Allow SetEnvIf[NoCase] to test environment variables as well
6174 as header fields and request attributes. [Ken Coar]
6176 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
6177 content-types are "text/html;parameters". PR#4524 [Ken Coar]
6179 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
6180 never accepted into any standard, and it opens up certain DoS
6181 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
6183 *) TestCompile updated. We can now run programs and output the
6184 results during the Configure process. [ Jim Jagielski]
6186 *) The source is now quad (long long) aware as needed. Specifically,
6187 the Configure process determines the correct size of off_t and
6188 *void. When the OS/platform/compiler supports quads, ap_snprintf()
6189 provides for the 'q' format qualifier (if quads are not available,
6190 'q' is silently "demoted" to long). [Jim Jagielski]
6192 *) When the username or password fed to htpasswd is too long, include the
6193 size limit in the error message. Also report illegal characters
6194 (currently only ':') in the username. Add the size restrictions
6195 to the man page. [Ken Coar]
6197 *) Fixed the configure --without-support option so it doesn't result in
6198 an infinite loop. [Marc Slemko]
6200 *) Piped error logs could cause a segfault if an error occured
6201 during configuration after a restart.
6202 [Aidan Cully <aidan@panix.com>] PR#4456
6204 *) If a "Location" field was stored in r->err_headers_out rather
6205 than r->headers_out, redirect processing wouldn't find it and
6206 the server would core dump on ap_escape_html(NULL). Check both
6207 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
6208 if Location isn't set. [Doug MacEachern, Ken Coar]
6210 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
6211 of the Expat 1.0.2 distribution. [Greg Stein]
6213 *) Replace regexec() calls with calls to a new API stub function
6214 ap_regexec(). This solves problems with DSO modules which use the regex
6215 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
6217 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
6218 environment variables can be set according to the protocol version
6219 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

6236 *) Support for server-parsed and multiview-determined ReadmeName and
6237 HeaderName files in mod_autoindex. Removed the restriction on
6238 "/"s in ReadmeName and HeaderName directives since the *sub_req*
6239 routines will deal with the access issues. (It's now possible to
6240 have {site|group|project|customer|...} wide readmes and headers.)

6255 by default when building with APACI; allow for platform-specific
6256 variable defaults in configure. [Wilfredo Sanchez]
6258 *) Do setgid() before initgroups() in http_main; some platforms
6259 zap the grouplist when setgid() is called. This was fixed in

6276 being newer than Configuration so that it is less likely to fail
6277 when using APACI and shadow sources. [Wilfredo Sanchez]
6279 *) PORT: Add initial support for Mac OS (versions 10.0 and
6280 greater). Use Mac OS X Server layout for now. Clean up dyld code
6281 in unix/os.c, and don't install the dyld error handlers, which
6282 are no longer needed in Mac OS. [Wilfredo Sanchez]
6284 *) Rename Rhapsody layout to "Mac OS X Server". Change install
6285 locations to appropriate ones for user-built (as opposed to
6286 system) installs. [Wilfredo Sanchez]
6288 *) Modify mod_autoindex's handling of AddDescription so that the
6289 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
6291 *) Add functionality to the install-bindist.sh script created by
6292 binbuild.sh to use tar when copying distribution files to the
6293 serverroot. This allows upgrading an existing installation
6294 without nesting the new distribution in the old.
6296 install-bindist.sh now detects the local perl5 path to install
6297 apxs and dbmmanage with proper path to perl interpreter.
6299 Add an install-binsupport target which copies the source files
6300 for apxs and dbmmanage to bindist to allow these scripts to
6301 be properly installed relative to the destination serverroot.

6417 *) Correct an apparent typo: on the Windows and MPE platforms, the
6418 htpasswd utility was limiting passwords to only 8 characters.
6421 *) EBCDIC platforms: David submitted patches for two bugs in the
6422 MD5 digest port for EBCDIC machines:
6423 a) the htdigest utility overwrote the old contents of the digest file
6424 b) the Content-MD5 header value (ContentDigest directive) was wrong
6425 when the returned file was not converted from EBCDIC, but was a
6426 binary (e.g., image file) in the first place.
6427 [David McCreedy <mccreedy@us.ibm.com>]
6429 *) support/htpasswd now permits the password to be specified on the
6430 command line with the '-b' switch. This is useful when passwords
6431 need to be maintained by scripts -- particularly in the Win32
6432 environment. [Ken Coar]
6434 *) Win32: Win32 multiple services patch. Added capability to install and
6435 run multiple copies of apache as individual services.
6438 apache -n apache1 -i -f c:/httpd.conf
6439 Installs apache as service 'apache1' and associates c:/httpd.conf

6465 mismatches were causing compilation problems with gcc -pedantic and

6468 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
6469 a roughly 5 fold speed up. [Brian Havard]
6471 *) proxy ftp: instead of using the hardwired string "text/plain" as
6472 a fallback type for files served by the ftp proxy, use the
6473 ap_default_type() function to determine the configured type.
6474 This allows for special configurations like
6475 <Directory proxy:ftp://some.host>
6476 DefaultType gargle/blurb
6478 Additionally, add the Content-Encoding: header to FTP proxy replies
6479 when the encoding is defined (by the AddEncoding directive).
6480 Because it was missing, it was almost impossible to browse compressed
6481 files using the FTP proxy (works now perfectly in Communicator).
6482 The ftp proxy now also returns the Date: and Server: header lines (if not
6483 much else... This code is "somewhat" broken) like normal requests do.
6486 *) Be more smart in APACI's configure script when determining the UID/GID
6487 for User/Group directives and use the determined UID/GID to initialize
6488 the permissions on the proxycachedir.
6489 [Dirk-Willem van Gulik, Ralf S. Engelschall]
6491 *) Changed the forking-prior-to-cleanup in the proxy module to first

6493 the number of fork()s from one/request to just the odd one an hour.
6494 [Dirk-Willem van Gulik]

6523 *) M_INVALID needed a value within the scope of METHODS so that unknown
6524 methods can be access controlled. [Roy Fielding] PR#3821
6526 *) Added PassAllEnv; makes server's entire environment available
6527 to CGIs and SSIs executed within directive's scope. [Ken Coar]
6529 *) ap_uuencode() always added two trailing '='s and encoding of
6530 8 bit characters on a machine with signed char may produced
6531 incorrect results. Additionally ap_uuencode() should now
6532 work correctly on EBCDIC platforms.
6533 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
6535 *) WIN32: Binary installer now runs the configuration DLL before
6536 the reboot prompt (which is only given if MSVCRT.DLL system
6537 DLL is new or updated). This should avoid the configuration
6538 directory being empty after installation. [Paul Sutton]
6539 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

6562 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
6563 for 8-bit safeness. [Dean Gaudet]
6565 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
6566 because SPARCs have a small machine-specific maximum size for the Global
6567 Offset Table which is often exceeded when compiling one of the larger
6568 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
6570 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

6594 *) Remove no longer used non-API function ap_single_module_init().
6595 [Ralf S. Engelschall]
6597 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
6600 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
6601 to make platform installations easier. [Wilfredo Sanchez]
6603 *) In configure, do not append the target name to the directory path if
6604 the path already contains "apache". [Ralf S. Engelschall]
6606 *) SIGPIPE is now ignored by the server core. The request write routines
6607 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
6608 correctly check for output errors and mark the connection as aborted.
6609 Replaced many direct (unchecked) calls to ap_b* routines with the
6610 analogous ap_r* calls. [Roy Fielding]
6612 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
6613 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
6614 Furthermore map lookups for non-existent keys are now cached as well.
6615 Additionally "txt" maps are now parsed with simple string functions
6616 instead of using ap_pregcomp(). As a side effect a bug that prevented
6617 the usage of keys containing the "," character was fixed.
6618 The changes drastically improve the performance when large rewrite maps
6620 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

6628 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
6629 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
6631 *) Add %V to mod_log_config, this logs the hostname according to the
6632 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
6633 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
6635 *) Add support for \n and \t to mod_log_config, can be used to produce
6636 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
6638 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
6640 *) Added informative error messages for failed munmap() and fseek() calls

6644 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
6646 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
6647 is removed. This allows <Directory proxy:*> directives to work and
6648 prevents invalid requests from killing the process.
6649 [Brian Havard <brianh@kheldar.apana.org.au>]

6655 David N. Welton: you can now have it generate an HTML TABLE, presumably
6656 for integration into other HTML sources. David updated the ab man page
6657 as well and added some missing descriptions. Thanks!
6658 [David N. Welton <davidw@prosa.it>]
6660 *) Win32: The filename validity checker now allows filenames containing
6661 characters in the range 0x80 to 0xff (for example accented characters).
6662 [Paul Sutton] PR#3890
6664 *) Added conditional logging based upon environment variables to
6665 mod_log_config. mod_log_referer and mod_log_agent
6666 are now deprecated. [Ken Coar]
6668 *) Allow apache acting as a proxy server to relay the real
6669 reason of a failure to a client rather than the "internal
6670 server error" it does currently. The general exposure mechanism
6671 can be triggered by any module by setting the "verbose-error-to"
6672 note to "*"; this allows more than just proxy errors to be exposed.
6673 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
6675 *) Moved man pages for ab and apachectrl to section 8.
6676 [Wilfredo Sanchez, Roy Fielding]
6678 *) Added -S option to install.sh so that options can be passed to
6679 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
6681 *) Tweak modules Makefile generated by Configure so that it handles
6682 the test case of no modules being selected. [chaz@reliant.com]
6684 *) Added a <LimitExcept method ...> sectioning directive that allows
6685 the user to assign authentication control to any HTTP method that
6686 is *not* given in the argument list; i.e., the logical negation
6687 of the <Limit> directive. This is particularly useful for controlling
6688 access on methods unknown to the Apache core, but perhaps known by
6689 some module or CGI script. [Roy Fielding, Tony Finch]
6691 *) Prevent apachectl from complaining if the PIDFILE exists but
6692 does not contain a process id, as might occur if the server is
6693 being rapidly restarted. [Wilfredo Sanchez]
6695 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
6697 *) Entity tag comparisons for If-Match and If-None-Match were not being
6698 performed correctly -- weak tags might cause false positives. Also,
6699 strong comparison wasn't properly enforced in all cases.
6700 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657

6705 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
6706 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
6708 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
6709 to util.c for parsing an HTTP header field value to extract the next
6710 list item, taking into account the possible presence of nested comments,
6711 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
6712 insignificant whitespace and lowercases non-quoted tokens.
6713 [Roy Fielding] PR#2065
6715 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
6716 code different from 500. This allows the proxy to, e.g., return
6717 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
6719 *) Fix ordering of language variants for the case where the traditional
6720 negotiation algorithm is being used with multiple language variants
6721 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
6723 *) Do not round the TCN quality calculation to 5 decimal places,
6724 unlike RFC 2296, because the calculation might need 12 decimal places
6725 to get the right result. [Roy Fielding]
6727 *) Remove unused code to disable transparent negotiation when
6728 negotiating on encoding only, as we now handle encoding too
6729 (though this is nonstandard for TCN), remove charset=ISO-8859-1
6730 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
6731 some debugging statements within mod_negotiation. [Koen Holtman]
6733 *) Fixed a rare memory corruption possibility in mod_dir if the index
6734 file is negotiable and no acceptable variant can be found.
6735 [Dean Gaudet, Roy Fielding, Martin Kraemer]
6737 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
6738 searching the Win32 registry for script interpreters.
6741 *) Win32: The compiled-in default filename for the error log is now
6742 error.log, which matches the default in the distributed httpd.conf.
6745 *) Win32: Any error messages from -i or -u command line options are now
6746 displayed on the console output rather than sent to the error log.
6747 Also the "Running Apache..." message is not output unless Apache is
6748 going to serve requests. [Paul Sutton]
6750 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
6751 and use a private significator ('$apr1$') to mark passwords as
6752 being smashed with our own algorithm. Also abstract the password
6753 checking into a new ap_validate_password() routine. [Ken Coar]
6755 *) Win32: The filename validity checker now allows "COM" but refuses
6756 access to "COM1" through "COM4". This allows filenames such
6757 as "com.name" to be served. [Paul Sutton] PR#3769.
6759 *) BS2000: Adapt to the new ufork() system call interface which will
6760 make subtasking easier on the OSD/POSIX mainframe environment.
6763 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
6764 ap_compat.h. [David White <david@persimmon.com>] PR#3725
6766 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
6767 use `.db' instead of `.pag' not only for FreeBSD, but also when
6768 the NDBM library looks like Berkeley-DB based.
6769 [Ralf S. Engelschall] PR#3773
6771 *) Add ability to handle DES or MD5 authentication passwords.
6772 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
6774 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
6776 *) SECURITY: Avoid some buffer overflow problems when escaping
6777 quoted strings. (This overflow was on the heap and we believe
6778 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
6780 *) Let src/Configure be aware of CFLAGS options starting with plus
6781 signs as it's the case for the HP/UX compiler.
6782 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
6784 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
6785 and check to see if the tar we wind up with supports '-h'.
6786 [Jim Jagielski] PR#3671
6788 *) A consistent and conservative style for all shell scripts has been
6789 implemented. Basically, all shell string tests use the traditional
6790 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
6791 to protect against bare null variable strings (ie: wrapping both
6792 sides with double quotes and prepending 'x'). 'x' was chosen
6793 because it's more universal and hopefully easier for old shell
6794 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
6797 *) The status module now prints out both the main server generation as
6798 well as the generation of each process. Also, the vhost info is
6799 printed with '?notable'. [Jim Jagielski]
6801 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
6802 and this makes its functions available to things in src/support.
6805 Changes with Apache 1.3.4
6807 *) Renamed macros status_drops_connection to ap_status_drops_connection
6808 and vestigial scan_script_header to ap_scan_script_header_err,
6809 mostly for aesthetic reasons. [Roy Fielding]
6811 *) The query switch "httpd -S" didn't exit after showing the
6812 vhost settings. That was inconsistent with the other query functions.
6815 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
6816 filename to the end of the STANDARD_MODULE_STUFF. Its
6817 presence at the beginning prevented reporting of the filename
6818 for modules compiled before 1 January 1999. [Ken Coar]
6820 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
6821 to detect and prevent access to special DOS device file names.
6822 [Paul Sutton, Ken Parzygnat]
6824 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
6825 and Makefile_win32_debug.txt (debug build) that work on Win95.
6826 Run each of the following from the src directory:
6827 nmake /f Makefile_win32.txt # compiles normal build
6828 nmake /f Makefile_win32.txt install # compiles and installs
6829 nmake /f Makefile_win32.txt clean # removes compiled junk
6830 nmake /f Makefile_win32_debug.txt # compiles debug build
6831 nmake /f Makefile_win32_debug.txt install
6832 nmake /f Makefile_win32_debug.txt clean
6835 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
6836 to build binary distributions. [Lars Eilebrecht]
6838 *) IndexOptions SuppressColumnSorting only turned off making
6839 the column headers anchors; you could still change the display
6840 order by manually adding a '?N=A' or similar query string to the
6841 URL. Now SuppressColumnSorting locks in the sort order so
6842 it can't be overridden this way. [Ken Coar]
6844 *) Added IndexOrderDefault directive to supply a default sort order
6845 for FancyIndexed directory listings. [Ken Coar] PR#1699
6847 *) Change the ap_assert macro to a variant that works on all platforms.
6848 [Richard Prinz <richard.prinz@cso.net>] PR#2575
6850 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
6851 search for an underscore on dlsym() (as it's already the case
6852 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
6854 *) Small fix for mod_env.html: The module was documented as to be _not_
6855 compiled into Apache per default, although it _IS_ compiled into
6856 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
6858 *) Instead of fixing a bug in the generation procedure for config.status (a
6859 backslash was missing) we remove the bug together with it's complete
6860 context because the special cases of the past can now no longer occur
6861 because of the recent magic for the --with-layout default.
6862 [Ralf S. Engelschall] PR#3590
6864 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
6865 making sure the src/support/ tools are _forced_ to be build last (they
6866 depend on other libraries).
6867 [Markus Theissinger <markus.theissinger@gmx.de>]
6869 *) Fix installation procedure: Now that os-inline.c is actually used (a
6870 recently fixed bug prevented this) we need to also install os-include.c
6871 in addition to os.h into the PREFIX/include/ location or building of
6872 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
6874 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
6875 allow us to distinguish between a garbled DSO (or even a file which isn't
6876 an Apache module DSO at all) and a DSO which doesn't match the current
6877 Apache API. [Ralf S. Engelschall] PR#3152
6879 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
6880 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
6881 match case insensitive (this especially avoids nasty patterns like
6882 `[tT][eE][sS][tT]'). Second two additional internal map functions
6883 `escape' and `unescape' were added which can be used to escape/unescape
6884 to/from hex-encodings in URLs parts (this is especially useful in
6885 combination with map lookups).
6886 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
6888 *) Renamed the macro escape_uri() to ap_escape_uri() which was
6889 forgotten (because it was a macro) in the symbol renaming process.
6890 [Ralf S. Engelschall]
6892 *) Fix some inconsistencies related to the scopes of directives. The only
6893 user visible change is that the directives `UseCanonicalName' and
6894 `ContentDigest' now use the (more correct) `Options' scope instead of
6895 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
6897 *) Using DSO, the Server token was being mangled. Specifically, the
6898 module's token was being added first before the Apache token. This
6899 has been fixed. [Jim Jagielski]
6901 *) Major overhaul of mod_negotiation.c, part 2.
6902 - properly handle "identity" within Accept-Encoding.
6903 - allow encoded variants in RVSA negotiation and let them appear in
6904 the Alternates field using the non-standard "encoding" tag-list.
6905 - fixed both negotiation algorithms so that an explicitly accepted
6906 encoding is preferred over no encoding if "identity" is not
6907 included within Accept-Encoding.
6908 - added ap_array_pstrcat() to alloc.c for efficient concatenation
6909 of large substring sequences.
6910 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
6913 *) Major overhaul of mod_negotiation.c, part 1.
6914 - cleanups to mod_negotiation comments and code structure
6915 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
6916 support for everything in the upcoming HTTP/1.1
6917 revision (draft-ietf-http-v11-spec-rev-06.txt).
6918 - language tag matching also handles tags with more than 2
6920 - empty Accept, Accept-Language, Accept-Charset headers are
6921 processed correctly; previously an empty header would make all
6922 values acceptable instead of unacceptable.
6923 - allowed for q values in Accept-Encoding
6924 - added support for transparent content negotiation (rfc2295 and
6925 rfc2296) (though we do not implement all features in these drafts,
6926 e.g. no feature negotiation). Removed old experimental version.
6927 - implemented 'structured entity tags' for better cache correctness
6928 (structured entity tags ensure that caches which can deal with Vary
6929 will (eventually) be updated if the set of variants on the server
6931 - this involved adding a vlist_validator element to request_rec
6932 - this involved adding the ap_make_etag() function to the global API
6933 - modified guessing of charsets used by Apache negotiation algorithm
6934 to guess 'no charset' if the variant is not a text/* type
6935 - added code to sort multiviews variants into a canonical order so that
6936 negotiation results are consistent across backup/restores and mirrors
6937 - removed possibility of a type map file resolving to another type map
6938 file as its best variant
6939 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
6941 *) RFC2396 allows the syntax http://host:/path (with no port number)
6942 but the proxy disallowed it (ap_proxy_canon_netloc()).
6943 [David Kristol <dmk@bell-labs.com>] PR#3530
6945 *) When modules update/modify the file name in the configfile_t structure,
6946 syntax errors will report the updated name, not the original one.
6947 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
6949 *) Correct some filename case assumptions from WIN32 to
6950 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
6952 *) For %v log ServerName regardless of the UseCanonicalName
6953 setting (similarly for %p). [Dean Gaudet]
6955 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
6956 rather late (too late for some invocations of TestCompile).
6957 This improves the make environment available to TestCompile and
6958 the *.module scripts. [Martin Kraemer]
6960 *) The hashbang emulation code in ap_execve.c would interpret
6961 #!/hashbang/scripts correctly, but failed to fall back to a
6962 standard shell for scripts which did NOT start with #!
6963 Now SHELL_PATH is started in these cases. [Martin Kraemer]
6965 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
6968 *) Update APXS manual page: some -q option arguments were missing
6969 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
6971 *) Cleanup the command line options: `-?' was documented to show
6972 the usage list but does it with an error because `?' is not a valid
6973 command. OTOH a lot of users expect `-h' to print such a usage list and
6974 instead are annoyed for ages by our huge unreadable list of directives.
6975 So we now changed the command line options this way:
6977 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
6978 very similar to the popular linker option.
6980 Intent: while -l gives the small list of modules, -L now gives the
6981 large list of directives implemented by these modules. This is also
6982 consistent with -v (short version info) and -V (large version info).
6984 Intent: it's now the expected option ;-)
6985 The manual page was adjusted accordingly.
6986 [Ralf S. Engelschall] PR#2714
6988 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
6989 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
6991 *) Removed recently introduced bugs and disfigurements in APACI:
6992 o fixed argument line processing: using $args was broken: It was not
6993 initialized and using args="$args $apc_option" and even args="$args
6994 \"$apc_option\"" fails in the second processing round for any arguments
6995 containing whitespaces. The only correct way is to use the construct
6996 "$@" (but not possible here) or iterate _both_ times over the implicit
6997 argument line (no argument to for-loop) which is what we now use.
6998 o make --with-layout=Apache the default without creating
6999 redundancy (copying the --with-layout block in the argument parsing
7000 loop). We achieve this by using the "$@" construct together with the
7001 `set' command to prepend --with-layout=Apache to the command line in
7002 case --with-layout is not used.
7003 o fixed auto-suffix handling now that config.layout exists.
7004 Paths which are auto-suffixed are marked with a trailing plus sign in
7005 config.layout and every path now can be marked this way (not only the
7006 four paths for which we do it currently). Additionally the suffix is
7007 no longer a static one. Instead it's now `/<target>' where <target> is
7008 the argument of the --target option or per default `httpd'.
7009 o allow also tabs (and only spaces) where we match whitespaces
7010 o various fixes and cleanups related to used shell coding style
7011 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7012 o trimmed output of --help to fit into 80 columns
7013 [Ralf S. Engelschall]
7015 *) Added two new core API functions, ap_single_module_configure() and
7016 ap_single_module_init(), which are now used by mod_so to configure a module
7017 after loading. [Ralf S. Engelschall]
7019 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
7020 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
7021 of ap_config.h to allow serialized accept for multiport listens.
7022 [Roy Fielding, Curt Sampson] PR#3120
7024 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
7025 of ap_config.h that would skip several defines if DEFAULT_GROUP
7026 was overridden. [Roy Fielding]
7028 *) PORT: The I86 version of DGUX has support for strncasecmp and
7029 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
7031 *) Fix ordering of definitions in ap_config.h so that ap_inline is
7032 defined before it might be used. [Victor Khimenko]
7034 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
7035 [Tom Serkowski <tks@bsdi.com>] PR#3453
7037 *) Make generation of src/Configuration.apaci more robust: It failed to
7038 differenciate between modules when one module name was a postfix of
7039 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
7040 just XXX (think about totally non-standard names like "apache_ssl", too).
7041 [Ralf S. Engelschall] PR#3380
7043 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
7044 since 1.3b7) and make whitespace handling more robust (it failed horrible
7045 when whitespaces were present in the arguments of -D options).
7046 [Ralf S. Engelschall] PR#3240
7048 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
7049 creates an external package shadow tree in DIR before the local build
7050 shadow tree is generated under DIR. This way one can have the extracted
7051 Apache distribution tree read-only on NFS or CDROM and still build Apache
7052 from these sources. An automatically triggered VPATH-like mechanism is
7053 provided through the TOP variable, too.
7054 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
7056 *) Fix negotiation so that a Vary response header is correctly
7057 generated when, for a particular dimension, variants only vary
7058 in having or not having a value for that dimension. [Paul Sutton]
7060 *) Fix negotiation so that we prefer an encoded variant over an
7061 unencoded variant if the user-agent explicitly says it can
7062 accept that encoding. Previously we always preferred the unencoded
7064 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
7066 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
7067 and the usage page was inconsistent with the functionality and manpage.
7068 [Ralf S. Engelschall]
7070 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
7071 They can occur multiple times and their arguments (`xxx') are passed AS
7072 IS to the compiler/linker command. [Ralf S. Engelschall]
7074 *) Fixed possible (but harmless in practice) bug in the DBM lookup
7075 procedure of mod_rewrite: very long keys were truncated.
7076 [Ralf S. Engelschall]
7078 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
7079 identifier, currently "Apache" and "GNU" are pre-defined in the file
7080 config.layout. Custom layouts are possible by using FILE:ID as the
7081 argument where the layout ID is taken from FILE.
7083 The config.layout file consists of <Layout ID>..</Layout> sections
7084 where inside those sections "path_variable: path_value" pairs can be
7085 specified. These lines are converted to path_variable='path_value'.
7087 *) Add a DefaultLanguage directive so that files missing a language
7088 extension (e.g., .fr, .de) can be labelled as being some other
7089 default language. DefaultLanguage can appear in <Directory> and
7090 <Files> containers as well as .htaccess files. [Paul Sutton]
7093 *) Fix TARGET configuration when configuring and installing using
7094 APACI configure. TARGET now defines the basename of the configuration
7095 file, startup script, manual page, etc. log_error_core() now reports
7096 the server binary name given by argv[0]. TARGET can now also be defined
7097 with --target=TARGET parameter passed to APACI configure.
7098 [Ralf Engelschall, Randy Terbush]
7100 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
7101 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

7123 *) Fallback to native compilers for IRIX-32 platform. It seems that
7124 a gcc 2.8.1 compiled apache is logging client addresses with all
7125 bits set (255.255.255.255). This is the second such problem caused

7205 in the Configuration[.apaci] file. Two special and important variants are
7206 supported for the option argument: first BEGIN:foo which permutes module
7207 mod_foo with the begin of the module list, i.e. it `moves' the module to
7208 the begin of the list (gives it lowest priority). And second foo:END
7209 which permutes mod_foo with the end of the module list, i.e. it `moves'
7210 the module to the end of the list (gives it highest priority).

7213 *) Fix problem with 'apache -k shutdown' and startup event
7214 synchronisation (Win32). [Ken Parzygnat <kparz@raleigh.ibm.com>]
7217 *) The config parser wasn't correctly noticing a missing '>'
7218 on container start lines (e.g., it wouldn't spot
7219 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom@us.ibm.com>]
7222 *) Add a 'RemoveHandler' directive which will selectively remove
7223 all handler associations for the specified file extensions.
7224 [Ryan Bloom <rbbloom@us.ibm.com>] PR#1799.
7226 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
7227 ResourceConfig directives on Win32. Also add a note to the effect
7228 of 'useless User directive ignored on Win32' to the errorlog if
7229 a User directive is encountered on Win32.
7230 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2078, 2303.
7232 *) Fix multiple whitespace handling in imagemaps for mod_imap which was
7233 broken since Apache 1.3.1 where we took out compressing of multiple
7234 spaces in ap_cfg_getline().
7235 [Ivan Richwalski <ivan@seppuku.net>] PR#3249
7237 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
7238 initialized correctly and the db_open() call used an invalid mode
7239 parameter. [Ron Klatchko <ron@ckm.ucsf.edu>] PR#3171
7241 *) PORT: DSO support for UnixWare 7
7242 [Ralf S. Engelschall, Ron Record <rr@sco.com>]
7244 *) Merge the contents of the {srm,access}.conf-dist* files into the
7245 httpd.conf-dist* files. The srm and access files now contain
7246 only comments, and httpd.conf has all the combined contents in
7247 a rational order. [Ken Coar]
7249 *) PORT: DSO/ELF support for FreeBSD 3.0.
7250 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
7252 *) Add a "default-handler" handler that calls the default_hander()
7253 function which is normally called for static content. This allows
7254 you to override a specific handler. [Marc Slemko]
7256 *) Further simplify checking for absolute paths by replacing an
7257 hard-coded syntax check with a call to a routine we already created to
7258 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
7260 *) Log an error if we encounter a malformed "require" directive
7261 in mod_auth if we know that we know that no other module can
7262 deal with it. [Marc Slemko]
7264 *) Remove ap_private_extern method of hiding conflicting symbols
7265 on the NEXT platform because it is not correct for all versions,
7266 and the versions for which it is correct are unknown.
7267 [Wilfredo Sanchez <wsanchez@apple.com>]
7269 *) Fix inheritance of IndexOptions NameWidth and remove unintended
7270 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]

7273 is encountered in an .htaccess file somewhere down the tree.
7276 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
7278 *) Fixed a segmentation violation in mod_proxy when a response is
7279 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
7281 Changes with Apache 1.3.3
7283 *) Added a complete implementation of the Expect header field as
7284 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
7285 response when we already know the final status, which is mighty
7286 useful for PUT responses that result in 302 or 401. [Roy Fielding]
7288 *) Remove extra trailing whitespace from the getline results as part
7289 of the protocol processing, which is extra nice because it works
7290 between continuation lines, is almost no cost in the normal case
7291 of no extra whitespace, and saves memory. [Roy Fielding]
7293 *) Added new HTTP status codes and default response bodies from the
7294 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
7295 HTTP Extension Framework (510) specifications. Did not add the
7296 WebDAV 424 and 425 codes because they are bogus. We don't use any
7297 of these codes yet, but they are now available to 3rd-party modules.
7300 *) Fix a possible race condition between timed-out requests and the
7301 ap_bhalfduplex select that might result in an infinite loop on
7302 platforms that do not validate the descriptor. [Roy Fielding]
7304 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
7305 running Apache server [Paul Sutton]
7307 *) Fix mod_autoindex bug where directories got a size of "0k" instead
7308 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]
7311 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker@jetair.be>]
7313 *) Add the server signature text (from the core ServerSignature directive)
7314 to the list of envariables available to scripts, SSI, and the like.
7317 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
7318 [M. Laak <maert@proinv.ee>] PR#3108
7320 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
7321 calculation in mod_status for all systems which don't have POSIX
7322 sysconf() (like UTS 2.1) and not only for the NEXT platform.
7323 [Dave Dykstra <dwd@bell-labs.com>] PR#3055
7325 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
7326 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
7327 instead of ap_getword(..., ' ') (which parses only according to spaces
7328 but not tabs). [James Morris <jmorris@intercode.com.au>,

7331 *) Fix the SERVER_NAME variable under sub-request situations (where
7332 `UseCanonicalName off' is used) like CGI's called from SSI pages or

7372 *) Reconstructed the loop through multiple htaccess file names so
7373 that missing files are not confused with unreadable files.
7376 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
7377 errno on an error, which leads to one error being mistaken for
7378 another when reading non-existent .htaccess files.
7381 *) OS/2: The new header tests get things right, need to update
7382 ap_config.h. [Brian Havard]

7396 *) Avoid possible line overflow in Configure: Use an awkfile to

7399 Changes with Apache 1.3.2
7401 *) Fix bug in ap_remove_module(), which caused problems for dso's
7402 who were the top_module. [Doug MacEachern]
7404 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
7405 mod_auth_db to both be friendly to users who wants to use this version
7406 and to avoid problems under platforms where only version 2.x is present.
7407 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
7409 *) When using ap_log_rerror(), make the error message available to the
7410 *ERROR_NOTES envariables by default. [Ken Coar]
7412 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
7413 You now must define a BS2000Account name for the server User.
7414 This has fewer security implications than the old approach.
7417 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
7418 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
7419 platform to make the braindead HPUX linker happy. Notice, for the module
7420 DSOs we don't have to use this, because these are loaded manually (and
7421 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
7423 *) Remove 64 thread limit on Win32.
7424 [Bill Stoddard <stoddard@raleigh.ibm.com>]
7426 *) Remove redundant substitutions in top-level Makefile.tmpl.
7427 [Ralf S. Engelschall]
7429 *) Fix APACI's `Group' configuration adjustment - especially for Linux
7430 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
7432 *) Make PrintPath work generically instead of having one version
7433 strictly for OS/2. [Jim Jagielski, Brian Havard]
7435 *) Fix the recently introduced C header file checking: We now use the C
7436 pre-processor pass only (and no longer the complete compiler pass) to
7437 determine whether a C header file exists or not. Because only this way
7438 we're safe against inter-header dependencies (which caused horrible
7439 portability problems). The only drawback is that we now have a CPP
7440 configuration variable which has to be determined first (we do a similar
7441 approach as GNU Autoconf does here). When all fails the user still has
7442 the possibility to override it manually via APACI or src/Configuration.
7443 As a fallback for the header check itself we can directly check the
7444 existance of the file under /usr/include, too.
7445 [Ralf S. Engelschall] PR#2777
7447 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
7448 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
7449 ap_private_extern defined to hide symbols that conflict with loaded
7450 dynamic libraries on the NEXT and RHAPSODY platforms.

7469 used -lprot. It's actually a bug in SCO5, of course.
7470 [Ronald Record <rr@sco.com>] PR#2533
7472 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
7473 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
7475 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
7476 platform, because it's only supported under version 4.0 and higher. But
7477 because our GuessOS is still unaware of Digital UNIX versions and the
7478 -msym is just to optimize the DSO statup time a little bit it's safe and
7479 best when we leave it out now. [Ralf S. Engelschall] PR#2969
7481 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
7482 functions: First all three functions no longer fail on strings containing
7483 "%" chars and second ap_log_printf() no longer does a double-formatting
7484 (instead it directly passes through the message to be formatted to the
7485 real internal formatting function). [Ralf S. Engelschall] PR#2941
7487 *) Allow "Include" directives anywhere in the server config
7488 files (but not .htaccess files). [Ken Coar] PR#2727
7490 *) The proxy was refusing to serve CONNECT requests except to
7491 port 443 (https://) and 563 (snews://). The new AllowCONNECT
7492 directive allows the configuration of the ports to which a
7493 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
7495 *) mod_expires will now act on content that is not sent from a file
7496 on disk. Previously it would never add an Expires: header to
7497 any response that did not come from a file on disk; the only
7498 case where it still doesn't (and can't) add one for that type of
7499 content is if you are using a modification date based setting.
7500 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
7502 *) Problems encountered during .htaccess parsing or CGI execution
7503 that lead to a "500 Server Error" condition now provide explanatory
7504 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
7507 *) Add NameWidth keyword to IndexOptions directive so that the
7508 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
7511 *) Recognize lowercase _and_ uppercase `uname' results under
7512 SCO OpenServer. [David Coelho <drc@ppt.com>]
7514 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
7515 a common problem of (mis-administrated?) IIS servers, make the apache
7516 proxy immune to these errors (and ignore the duplicates, but log
7517 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
7519 *) The <IfModule and <IfDefine block starting directives now only
7520 allow exactly one argument. Previously, the optional negation
7521 character '!' could be separated by whitespace without a syntax
7522 error being reported, albeit defeating the IfModule functionality
7523 (enclosed directives would ALWAYS be executed). By using the
7524 stricter syntax, these hard-to-track errors can be avoided.
7527 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
7528 cause the standalone FancyIndexing directive to logically OR
7529 into any existing IndexOptions settings rather than wiping
7530 them out. [Ken Coar]
7532 *) Changes in ftp proxy: make URL parsing simpler by using the
7534 + Add display of the "current directory" in cases where it's
7535 different from the supplied path (e.g., ftp://user@host/ lives
7536 in /home/user, not in /, therefore clicking on "../" in the
7537 starting directory might send us to /home/).
7538 + When ftp login fails, (esp. when a user name was part of the
7539 URL already), we now return [401 Unauthorized ] to allow the
7540 browser to pop up an authorization dialog. This makes passwords
7541 slightly less visible (they don't appear in the regular log files)
7542 and implements a functionality that other www proxy servers
7546 *) Triggered by the recent "Via:" header changes, the proxy module would
7547 dump core for replies with invalid headers (e.g., duplicate
7548 "HTTP/1.0 200 OK" lines). These errors are now logged and the
7549 core dump is avoided. Also, broken replies are not cached.
7550 [Martin Kraemer] PR#2914
7552 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
7553 plop gmon.out profile data for each child [Doug MacEachern]
7555 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
7556 config.status script to be immune against arguments with whitespaces.
7557 [Yves Arrouye <yves@apple.com>] PR#2866
7559 *) Replace the inlined information grabbing stuff for the configuration
7560 adjustment feature (no --without-confadjust) with calls to a new helper
7561 script `buildinfo.sh' which is both more flexible and already proofed to
7562 be more robust against platform differences. This mainly fixes the
7563 recently occured ``sed: command garbled: ...'' problems.
7564 [Ralf S. Engelschall] PR#2776, PR#2848
7566 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
7567 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
7568 without complains after we recently added the POST feature.
7569 [Ralf S. Engelschall]
7571 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
7572 modules as API functions and we forgot them at the big symbol renaming.
7573 [Ralf S. Engelschall]
7575 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
7576 [Youichirou Koga <y-koga@jp.FreeBSD.ORG>] PR#2895

7581 *) Add the ability to do POST requests to the ab benchmarking tool.
7582 [Kurt Sussman <kls@best.com>] PR#2871
7584 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
7585 5 to 10 because there are some users out there who always have 5 to 8
7586 variables in one RewriteRule and had to patch mod_rewrite.h for every
7587 release. So 15 should be now more than enough, even for them. (I never
7588 needed more than 4 in my RewriteRules ;-)
7589 [Ralf S. Engelschall]
7591 *) Make the proxy generate and understand Via: headers
7594 *) Change the proxy to use tables instead of array_headers for
7595 the header lines. [Martin Kraemer]
7597 *) Make sure the config.status file is not overridden when just
7598 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
7600 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
7601 provide a way to trace API changes that add functionality but do
7602 not create a compatibility issue for precompiled modules, etc.
7603 See include/ap_mmn.h for more details. [Randy Terbush]
7605 *) Fix suexec installation under `make install root=xxx' situation.
7606 [Ralf S. Engelschall]
7608 *) Extend the output of the -V switch to include the paths of all
7609 compiled-in configuration files, if they were overridden at
7610 compile time, for least astonishment of the user.
7613 *) When READing a request in ExtendedStatus mode, the "old"
7614 vhost, request and client information is not displayed.
7617 *) STATUS is no longer available. Full status information now
7618 run-time configurable using the ExtendedStatus directive.
7621 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
7622 cpu time attacks) in header parsing. Add ap_overlap_tables(),
7623 a function which can be used to perform bulk update operations
7624 on tables in a more efficient manner. CAN-1999-1199 (cve.mitre.org)
7627 *) SECURITY: Added compile-time and configurable limits for
7628 various aspects of reading a client request to avoid some simple
7629 denial of service attacks, including limits on maximum request-line
7630 size (LimitRequestLine), number of header fields (LimitRequestFields),
7631 and size of any one header field (LimitRequestFieldsize). Also added
7632 a configurable directive LimitRequestBody for limiting the size of the
7633 request message body. [Roy Fielding]
7635 *) Make status module aware of DNS and logging states, even if
7636 STATUS not defined. [Jim Jagielski]
7638 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
7640 *) Enhance mod_speling so that CheckSpelling can be used in
7641 <Directory> containers and .htaccess files. [Ken Coar]
7643 *) API: new ap_custom_response() function for hooking into the
7644 ErrorDocument mechanism at runtime [Doug MacEachern]
7646 *) API: new ap_uuencode() function [Doug MacEachern]
7648 *) API: scan_script_header_err_core() now "public" and renamed
7649 ap_scan_script_header_err_core() [Doug MacEachern]
7651 *) The 'status' module will now show the process pid's and their
7652 state even without full STATUS accounting. [Jim Jagielski]
7654 *) Restore the client IP address to the error log messages, this
7655 was lost during the transition from 1.2 to 1.3. Add a new
7656 function ap_log_rerror() which takes a request_rec * and
7657 formats it appropriately. [Dean Gaudet] PR#2661
7659 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
7660 whitespace in input lines -- including within quoted strings.
7662 but leading and trailing whitespace should continue to be
7663 stripped [Martin Kraemer]
7665 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
7666 the ugly use of an env. variable and use command-line args for
7667 alternate $PATH. Make more like advanced 'type's as well.
7670 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
7671 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
7672 <alain.st-denis@ec.gc.ca>] PR#2736
7674 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
7676 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
7677 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
7678 directory was renamed to src/os/os2/ for consistency.
7679 [Brian Havard, Ralf S. Engelschall]
7681 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
7682 files (here modules) against other DSO files (here shared libraries).
7683 This is done by determining a subset of LIBS which can be safely used for
7684 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
7685 disabled for all platforms to avoid problems with this (experimental)
7686 rule. But we provide it now for those people how ran into problems and
7687 want to came out by forcing linking against DSOs.
7688 [Ralf S. Engelschall] PR#2587
7690 *) Fix suEXEC start message: Has to be of `notice' level to really get
7691 printed together with the standard startup message because the `notice'

7699 [Youichirou Koga <y-koga@jp.FreeBSD.org>, Ralf S. Engelschall] PR#2756
7701 *) Allow ap_read_request errors to propagate through the normal request
7702 handling loop so that the connection can be properly closed with
7703 lingering_close, thus avoiding a potential TCP reset that would
7704 cause the client to miss the HTTP error response. [Roy Fielding]
7706 *) One more portability fix for APACI shadow tree support: Swap order of awk

7994 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
7996 *) Improve performance of directory listings (mod_autoindex) by comparing
7997 integer keys (last-modified and size) as integers rather than converting
7998 them to strings first. Also use a set of explicit byte tests rather
7999 than strcmp() to check for parent directory-ness of an entry. Oh, and
8000 make sure the parent directory (if displayed) is *always* listed first
8001 regardless of the sort key. Overall performance winnage should be good
8002 in CPU time, instruction cache, and memory usage, particularly for large
8003 directories. [Ken Coar]
8005 *) Add a tiny but useful goody to APACI's configure script: The generation
8006 of a config.status script (as GNU Autoconf does) which remembers the used
8007 configure command and hence can be used to restore the configuration by
8008 just re-running this script or for remembering the configuration between
8010 [Ralf S. Engelschall]
8012 *) Add httpd -t (test) option for running configuration syntax tests only.
8013 If something is broken it complains and exits with a return code
8014 non-equal to 0. This can be used manually by the user to check the Apache
8015 configuration after editing and is also automatically used by apachectl
8016 on (graceful) restart command to make sure Apache doesn't die on restarts
8017 because of a configuration which is now broken since the last (re)start.
8018 This way `apachectl restart' can be used inside cronjobs without having
8019 to expect Apache to be falling down. Additionally the httpd -t can be run
8020 via `apachectl configtest'.

8174 proxy errors to be treated by ErrorDocument's as well. For this
8175 purpose, a new module-to-core communication variable "error-notes"

8177 its error text using this variable. Its content is copied to a new
8178 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.

8203 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
8204 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252
8206 *) Fix src/support/httpd.exp (DSO export file which is currently only
8207 used under AIX) because of recent changes to function names.
8208 [Ralf S. Engelschall]
8210 Changes with Apache 1.3b7
8212 *) Make sure a MIME-type can be forced via a RewriteRule even when no
8213 substitution takes place, for instance via the following rule:
8214 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
8215 requested by users in the past to force a single script without a .cgi
8216 extension and outside any cgi-bin dirs to be executed as a CGI program.
8217 [Ralf S. Engelschall] PR#2254
8219 *) A fix for protocol issues surrounding 400, 408, and
8220 414 responses. [Ed Korthof]
8222 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
8224 *) Fix discrepancy in proxy_ftp.c which was causing failures when
8225 trying to connect to certain ftpd's, such as anonftpd.
8226 [Rick Ohnemus <rick@ecompcon.com>]
8228 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
8229 logfile instead of fiddling around itself with child spawning stuff.
8230 [Ralf S. Engelschall]
8232 *) Made RefererIgnore case-insensitive.
8234 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
8237 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
8238 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
8241 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
8243 *) Fix support script `dbmmanage': It was unable to handle some sort
8244 of passwords, especially passwords with "0" chars.
8245 [Ralf S. Engelschall] PR#2242
8247 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
8248 [Ben Laurie] PR#2238
8250 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
8251 library), so CGI handling has been changed to use Win32 native handles
8252 instead of C file descriptors.
8253 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
8255 *) The proxy cache would store an incorrect content-length in the cached
8256 file copy after a cache update. That resulted in repeated fetching
8257 of the original copy instead of using the cached copy.
8258 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
8260 *) The Makefiles assumed that DSO files are build via $(LD). This
8261 is broken for two reasons: First we never defined at least LD=ld
8262 somewhere to make sure this works (it was silently assumed that most Make
8263 provide a built-in LD definition - ARGL!) and second using the generic LD
8264 variable is not the truth. Instead a special variable named LD_SHLIB is
8265 reasonable because although "ld" is usually the default, the command for
8266 building DSO files can be "libtool" or even "cc" on some systems.
8267 [Ralf S. Engelschall]
8269 *) Replace the AddVersionPlatform directive with ServerTokens which
8270 provides for more control over the format of the Server:
8271 header line. SERVER_SUBVERSION is no longer supported;
8272 all module should use the ap_add_version_component()
8273 API function instead. [Jim Jagielski]
8275 *) Support for the NCR MP/RAS 3.0
8276 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
8278 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
8279 not retrieved in src/Configure and thus was not useable.
8280 [Ralf S. Engelschall]
8282 *) Various Makefile consistency cleanups:
8283 - make OSDIR also automatically be relative to src/ like INCDIR
8284 - SUBDIRS is now generated in src/Makefile only and not in
8285 Makefile.config because it is a local define for this location.
8286 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
8287 any Makefile but make sure that at least the "-K inline" is kept in
8289 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
8290 - updated the dependencies theirself
8291 - removed not existing SHLIB variable from "clean" targets
8292 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
8293 already exists and OBJS_PIC are also just plain objects and have not
8294 directly to do with "shared" things. The only difference is that they
8295 contain PIC. So OBJS_PIC is the more canonical name.
8296 - Updated the Makefile-dependency lines for OBJS_PIC
8297 - Removed the Makefile-dependency line in Configure to avoid double
8299 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
8300 of xxx.lo as GNU libtool does with its PIC objects
8301 - reduce local complexity in modules Makefile.tmpl by moving the last
8302 existing target "depend" to the generation section in Configure, too.
8303 - removed the historical $(SPACER) which was used in the past together
8304 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
8305 is no longer needed.
8306 - force the build and run of the gen_xxx programs under main/ as the
8307 first step before building the objects because it looks cleaner
8308 [Ralf S. Engelschall]
8310 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
8313 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
8316 *) WIN32: Don't force ISAPI headers to finish with \n.
8317 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
8319 *) When opening "configuration" files (like httpd.conf, htaccess
8320 and htpasswd), Apache will not allow them to be non-/dev/null
8321 device files. This closes a DoS hole. At the same time,
8322 we use ap_pfopen to open these files to handle timeouts.
8323 [Jim Jagielski, Martin Kraemer]
8325 *) Apache will now log the reason its httpd children exit if they exit
8326 due to an unexpected signal. (It requires a new porting define,
8327 SYS_SIGLIST, which if defined should point to a list of text
8328 descriptions of the signals available. See PORTING.) [Dean Gaudet]
8330 *) WIN32: chdir() doesn't make sense in a multithreaded environment
8331 like WIN32. Before, Win32 CGI's could have had sporadic failures
8332 if a chdir call from one thread was made between another chdir call
8333 and a spawn in another thread. So, for now don't chdir for CGI scripts
8334 in WIN32. The current CGI "spec" is unclear as to whether it's
8335 necessary. Long-term fix is to either serialize the chdir/spawn combo
8336 or use WIN32 native calls to spawn a process. This temp fix was
8337 necessary to remove this as a showstopper for 1.3's release.
8340 *) Cleanup the suEXEC support in APACI and make it more safe:
8341 1. Add big fat hint in INSTALL about risks and to read the
8342 htdocs/manual/suexec.html document before using the suexec-related
8344 2. Make sure the user has at least provided one --suexec-xxxx option
8345 (specifies suEXEC parameters) in addition to --enable-suexec option.
8346 If only --enable-suexec is given APACI stops with a hint to INSTALL
8347 and htdocs/manual/suexec.html documents.
8348 3. Provide two additional --suexec-xxxx options to make the suEXEC
8349 configuration complete (especially for package maintainers who else
8350 had to patch the source tree) by providing ways to configure minimal
8351 UID/GID and safe PATH, too.
8352 [Ralf S. Engelschall]
8354 *) Cleanup of the `configure --shadow' process:
8355 - make sure the configure script creates its temporary files in the
8356 shadow tree to avoid conflicts with parallel configure runs
8357 - removed unnecessary option "-r" from "rm" call for Makefiles
8358 - make sure the configure scripts creates the shadow-wrapper Makefile
8359 only when no shadow trees already exists
8360 - make sure "make distclean" removes the shadow-wrapper Makefile but only
8361 when no more shadow trees exists
8362 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
8363 as fast (in the past it needed 70sec, now it runs just 38sec)
8364 - make sure CVS does not complain about the created files
8365 Makefille.<gnutriple> and directories src.<gnutriple>
8366 [Ralf S. Engelschall]
8368 *) Added the ap_add_version_component() API routine and the
8369 AddVersionPlatform core directive. The first allows modules to
8370 declare themselves in the Server response header field value,
8371 augmenting the SERVER_SUBVERSION define in the Configuration file
8372 with run-time settings (more useful in a loadable-module environment).
8373 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
8374 into the server version string. [Ken Coar] PR#2056
8376 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
8379 *) Emit the "Accept-Range" header for the default handler.
8380 [Brian Behlendorf] PR#1464
8382 *) Add a note to httpd.conf-dist that apache will on some systems fail
8383 to start when the Group # is set to a negative or large positive value.
8386 *) Make sure the module execution order is correct even when some modules
8387 are loaded under runtime (`LoadModule') via the DSO mechanism:
8388 1. The list of loaded modules is now a dynamically allocated one
8389 and not the original statically list from modules.c
8390 2. The loaded modules are now correctly setup by LoadModule for
8391 later use by the AddModule command.
8392 3. When the DSO mechanism for modules is used APACI's `install'
8393 target now enables all created `LoadModule' lines per default because
8394 this is both already expected by the user _and_ needed to avoid
8395 confusion with the next point and reduces the Makefile.tmpl complexity
8396 4. When the DSO mechanism for modules is used, APACI's `install'
8397 target now additionally makes sure the module list is reconstructed
8398 via a complete `ClearModuleList+AddModule...' entry.
8399 5. The support tool `apxs' now also makes sure an AddModule command
8400 is added in addition to the LoadModule command.
8401 6. The modules.c generation was extended to now contain two
8402 comments to make sure no one is confused by the confusing terminology
8403 of loading/linking (we use load=link+load & link=activate instead of
8404 the obvious load=activate & link=link :-( )
8405 This way now there is no longer a difference under execution time between
8406 statically and dynamically linked modules.
8407 [Ralf S. Engelschall]
8409 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
8410 Big Symbol Renaming. [Ralf S. Engelschall]
8412 *) Add a comment to mod_example.c showing the format of a FLAG command
8415 *) Standardized the time format in mod_status to match that of other
8416 places in the code (e.g. DATE_GMT). PR#1551
8418 *) Fix handling of %Z in timefmt strings for those platforms with no time
8419 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
8422 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
8423 feature compatible with 'UseCanonicalName off' by changing
8424 r->server->server_hostname to ap_get_server_name(). And I changed some
8425 functions which use r->server->port to use ap_get_server_port() instead,
8426 because if there's no Port directive in the config r->server->port is 0.
8429 *) get/set_module_config are trivial enough to be better off inline. Worth
8430 1.5% performance boost. [Dean Gaudet]
8432 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
8433 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
8436 *) [BS2000 security] BS2000 needs an extra authentication to initialize
8437 the task environment to the unprivileged User id. Otherwise CGI scripts
8438 would have a way to gain super user access. [Martin Kraemer]
8440 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
8441 absolute path, only log base name of logging source as is done
8442 in unix. [Martin Kraemer]
8444 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
8445 the encoding type from the Accept-Encoding header (if it's there)
8446 and use it in the response, as that's probably what it'll be expecting.
8447 [Ronald.Tschalaer@psi.ch]
8449 *) Fix to mod_alias: translate_alias_redir is dealing with
8450 a URI, not a filename, so the check for drive letters for win32
8451 and emx is not necessary. [Dean Gaudet]
8453 *) WIN32: Allow .cmd as an executable extension.
8454 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
8456 *) Make Apache header files, and some variables, C++ friendly.
8457 [Michael Anderson's <mka@redes.int.com.mx>]
8459 *) Child processes can now "signal" (by exiting with a status
8460 of APEXIT_CHILDFATAL) the parent process to abort and
8461 shutdown the server if the error in the child process was
8462 fatal enough. [Jim Jagielski]
8464 *) mod_autoindex's find_itme() was sensitive to MIME type case.
8465 [Jim Jagielski] PR#2112
8467 *) Make sure the referer_log and agent_log entries in the default httpd.conf
8468 file are also adjusted for the actual relative installation paths.
8469 [Ralf S. Engelschall] PR#2175
8471 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
8473 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
8476 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
8477 Additionally the checks for finding the vendor DSO library were moved
8478 from mod_so.c to Configure because first it needs $PLAT etc. and second
8479 mod_so already uses an abstraction layer and does not fiddle with the
8480 vendor functions itself.
8481 [Jens-Uwe Mager, Ralf S. Engelschall]
8483 *) PORT: Some optimization defines for NetBSD
8484 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
8486 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
8487 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
8489 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
8490 AIX variants should work fine, too. Even AIX 3.x should work). This is
8491 accomplished by using the free DSO emulation code from Jens-Uwe Mager
8492 which we put into a os/unix/os-dso-aix.c file.
8493 [Ralf S. Engelschall]
8495 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
8496 that we should use NET_SIZE_T == int but the include files force size_t.
8497 [Ralf S. Engelschall]
8499 *) Fix two bugs in select() handling in http_main.c.
8502 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
8503 is unset (as it is in situations like timeouts) where it is unclear
8504 whether errno is set or not. [Martin Kraemer]
8506 *) Just having APACI's localstatedir is too general and not enough for most
8507 of the systems. 1.3b6 again required manual APACI patches by package
8508 maintainers from Red Hat and FreeBSD because for their filesystem layout a
8509 little bit more flexibility in configuring the paths is needed. Hence we
8510 provide three additional configure options (--runtimedir, --logfiledir,
8511 --proxycachedir) which now can be used for more granular adjustments if
8512 --localstatedir is not enough to fit the particular needs. As a nice
8513 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
8514 [Ralf S. Engelschall]
8516 *) Make the install root for "make install" in APACI's Makefile overrideable
8517 by package authors. This way we are even more friendly to package
8518 maintainers (especially Debian and Red Hat) who build for the real prefix
8519 via "configure --prefix=/<real>" but use a different local prefix via
8520 "make root=/tmp/apache install" for rolling the package without bristling
8521 the target location on their system.
8522 [Ralf S. Engelschall]
8524 *) Workaround sed limitations in APACI's configure script by now
8525 substituting in chunks of 50 commands (because for instance HPUX's vendor
8526 sed has a limit of max. 98 commands)
8527 [Ralf S. Engelschall] PR#2136
8529 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
8530 [Ralf S. Engelschall] PR#2140
8532 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
8533 RENAMING process because they are defined as pre-processor macros instead
8534 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
8535 [Ralf S. Engelschall]
8537 *) Workaround braindead AWK's when generating ap_config.h: The split() and
8538 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
8539 [Ralf S. Engelschall] PR#2139
8541 *) Various bugfixes and cleanups for the APACI configure script:
8542 o fix IFS handling for _nested_ situation
8543 o fix Perl interpreter search: take first one found instead of last one
8544 o fix DSO consistency check
8545 o print error messages to stderr instead of stdout
8546 o add install-quiet for --shadow situation to Makefile stub
8547 o reduce complexity by avoiding sed-hacks for rule and module list loops
8548 [Ralf S. Engelschall]
8550 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
8552 *) Make sure the input field separator (IFS) shell variable is explicitly
8553 initialized correctly before _every_ `for' loop and also restored after
8554 the loops. [Ralf S. Engelschall]
8556 *) Make sure that "make install" doesn't overwrite the `mime.types' and
8557 `magic' files from an existing Apache installation. Because people often
8558 customize these for own MIME and content types.
8559 [Ralf S. Engelschall]
8561 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
8562 [Peter Galbavy, Ralf S. Engelschall] PR#2109
8564 *) Fix the path to the ScoreBoardFile in the install-config target, too.
8565 [Ralf S. Engelschall] PR#2105
8567 *) Let "configure" clear out the users parameters (provided as shell
8568 variables) to avoid side-effects in "src/Configure" when the user
8569 exported them (which is not needed, but some users do it).
8570 [Ralf S. Engelschall] PR#2101
8572 *) Provide backward compatibility from some old src/Configuration.tmpl
8573 parameter names to the canonical Autoconf-style shell variable names. For
8574 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
8575 but a hint message is displayed. [Ralf S. Engelschall]
8577 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
8578 CGI scripts from an existing Apache installation.
8579 [Ralf S. Engelschall, Jim Jagielski] PR#2084
8581 *) Make `configure --compat' more "compatible" by first
8582 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
8583 second by making sure the "avoid-bristling-suffix" /apache is not
8584 appended to sysconfdir, datadir, localstatedir and includedir when
8585 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
8587 *) NeXT required strdup() in support/logresolve.c
8588 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
8590 *) AIX required sys/select.h in support/ab.c
8591 [Jens Schleusener <Jens.Schleusener@dlr.de>] PR#2081
8593 *) Fix the path to the MimeMagicFile in the install-config target, too.
8594 [Ralf S. Engelschall] PR#2089
8596 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
8598 *) If you start apache with the -S command line option it will dump
8599 out the parsed vhost settings. This is useful for folks trying
8600 to figure out what is wrong with their vhost configuration.
8601 (Other dumps may be added in the future.) [Dean Gaudet]
8603 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
8604 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
8607 *) Because /usr/local/apache is the default prefix the ``configure
8608 --compat'' option no longer has to set prefix, again. This way the
8609 --compat option honors a leading --prefix option. [Lars Eilebrecht]
8611 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
8612 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
8613 to avoid "discard const" warnings. [Ralf S. Engelschall]
8615 *) If a specific handler is set for a file yet the request still
8616 ends up being handled by the default handler, log an error
8617 message before handling it. This catches things such as trying
8618 to use SSIs without mod_include enabled. [Marc Slemko]
8620 *) Fix error logging for the startup case where ap_log_error() still uses
8621 stderr as the target. Now the default log level is honored here, too.
8622 [Ralf S. Engelschall]
8624 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
8625 long" errors when generating the MODULES entry for src/Makefile
8626 [Ben Hyde, Ralf S. Engelschall]
8628 *) Make sure src/Configure doesn't complain about the old directory
8629 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
8631 Changes with Apache 1.3b6
8633 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
8635 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
8636 interface via the similar but proprietary HP/UX shl_xxx-style system
8637 calls. [Ralf S. Engelschall]
8639 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
8640 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
8641 Make. [Ralf S. Engelschall]
8643 *) ++++ THE BIG SYMBOL RENAMING ++++
8644 To avoid symbol clashes with third-party code compiled into the server,
8645 we globally applied the prefix "ap_" to the following classes of
8647 - Apache provided general functions (e.g., ap_cpystrn)
8648 - Public API functions (e.g., palloc, bgets)
8649 - Private functions which we can't make static (because of
8650 cross-object usage) but should be (e.g., new_connection)
8651 For backward source compatibility a new header file named compat.h was
8652 created which provides defines for the old symbol names and can be used
8653 by third-party module authors.
8656 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
8657 problem under SVR4 is that there is no command flag to force the linker
8658 to export the global symbols of the httpd executable therewith they are
8659 available to the DSO's. Instead of problematic hacks like creating a
8660 dummy.so file (containing dummy references to all global symbols) the
8661 httpd binary is linked against, we use a clean trick stolen from Perl 5:
8662 Placing the Apache core code itself into a DSO library named libhttpd.so.
8663 This way the global symbols _HAVE_ to be exported and thus are available
8664 to any manually loaded DSO's under runtime. To reduce the impact to the
8665 user to null we go even further and create a stub httpd executable which
8666 automatically keeps track of the DSO library loading itself and thus
8667 hides the complete mechanism from the user. Although the generation of
8668 this DSO library is automatically triggered for platforms which
8669 essentially need it (mostly all SVR4-derivates) it can be also enabled
8670 manually via the Rule SHARED_CORE. This can be interesting in the future
8671 where we perhaps exploit this libhttpd.so mechanism for providing nifty
8672 features like graceful upgrades, or whatever.
8673 [Ralf S. Engelschall, Martin Kraemer]
8675 *) Build the libraries before building the rest of the tools. [Ben Hyde]
8677 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
8678 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
8679 conventions while "clean" removes only stuff created by "all" targets,
8680 "distclean" additionally removes the stuff from the configuration
8681 process. This way "make distclean" (hence the name) provides a fresh
8682 source tree as it was for distribution.
8683 [Ralf S. Engelschall]
8685 *) Allow top-level (APACI) Makefile to break on build errors
8686 the same way the src/ subtree Makefiles breaks on them by replacing the
8687 initial APACI sed-subdir-display-kludge with a more clean
8688 variable-passing-solution: variable SDP can optionally hold the subdir
8689 prefix which is consistently used for displaying the subdir movement.
8690 This way even the top-level Makefile can stop correctly on errors as the
8691 user expects. [Ralf S. Engelschall]
8693 *) Fixed ordering of argument checks for RewriteBase directive.
8694 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
8696 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
8697 indicating that a module is being compiled for dynamic loading. Also
8698 remove #define IS_MODULE from modules and add SHARED_MODULE define
8699 to the mak/dsp files. [Alexei Kosut]
8701 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
8702 since we are now logging APLOG_WARNING by default. [Roy Fielding]
8704 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
8706 *) Add documentation file and src/Configuration.tmpl entry for the
8707 experimental mod_mmap_static module. Because although it is and marked as
8708 an experimental one it is distributed and thus should be documented and
8709 prepared for configuration the same way as all others modules.
8710 [Ralf S. Engelschall]
8712 *) Add query (-q) option to apxs support tool to be able to manually query
8713 specific settings from apxs. This is needed for instance when you
8714 manually want to access Apache's header files and you need to assemble
8715 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
8716 [Ralf S. Engelschall]
8718 *) Now src/Configure uses a fallback strategy for the shared object support
8719 on platforms where no explicit information is available: If a Perl
8720 installation exists we ask it about its shared object support and if it's
8721 the dlopen-style one we shamelessly guess the compiler and linker flags
8722 for creating shared objects from Perls knowledge. Of course, the user is
8723 warning about what we are doing and informed that he should send us
8724 the guessed flags when they work. [Ralf S. Engelschall]
8726 *) Provide APACI --without-support option to be able to disable the build
8727 and installation of the support tools from the src/support/ area.
8728 Although its useful to have these installed per default we should provide
8729 a way to compile and install without them for backward-compatibility.
8730 [Ralf S. Engelschall]
8732 *) Add of the new APache eXtenSion (apxs) support tool for building and
8733 installing modules into an _already installed_ Apache package through the
8734 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
8735 this approach actually doesn't need the Apache source tree. The
8736 (APACI-installed) server package is enough, because this now includes the
8737 Apache C header files (PREFIX/include) and the new APXS tool
8738 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
8739 module authors to build their Apache modules _OUTSIDE_ the Apache source
8740 tree while avoiding them to fiddle around with the totally platform
8741 dependend way of compiling DSO files. The tool supports all ranges of
8742 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
8743 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
8744 on-the-fly generate a minimalistic Makefile and sample module for the
8745 first step to provide both a quick success event and to demonstrate the
8746 APXS mechanism to module authors. [Ralf S. Engelschall]
8748 *) Fix core dumps in use of CONNECT in proxy.
8749 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
8751 *) Modify the log directives in httpd.conf-dist files to use CustomLog
8752 so that users have examples of how CustomLog can be used.
8755 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
8756 the Apache distribution tree. Until Apache 1.3 there was no real
8757 out-of-the-box batch-capable build and installation procedure for the
8758 complete Apache package. This is now provided by a top-level "configure"
8759 script and a corresponding top-level "Makefile.tmpl" file. The goal is
8760 to provide a GNU Autoconf-style frontend which is capable to both drive
8761 the old src/Configure stuff in batch and additionally installs the
8762 package with a GNU-conforming directory layout. Any options from the old
8763 configuration scheme are available plus a lot of new options for flexibly
8764 customizing Apache. [Ralf S. Engelschall]
8766 *) The floating point ap_snprintf code wasn't threadsafe.
8767 Had to remove the HAVE_CVT macro in order to do threadsafe
8768 calling of the ?cvt() floating point routines. [Dean Gaudet]
8770 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
8772 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
8773 [Jim Jagielski] PR#1901
8775 *) BUG: Configure was using TCC and CC inconsistently. Make sure
8776 Configure knows which CC we are using. [Jim Jagielski]
8778 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
8779 was defined in a parent directory. [Lars Eilebrecht]
8781 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
8782 a generic printf-style routine that can call arbitrary output
8783 routines. Use this to replace http_bprintf.c. Add new routines
8784 psprintf(), pvsprintf() which allocate the exact amount of memory
8785 required for a string from a pool. Use psprintf() to clean up
8786 various bits of code which used ap_snprintf()/pstrdup().
8789 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
8790 ap_snprintf() has different semantics and formatting codes than
8791 snprintf(). [Dean Gaudet]
8793 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
8794 is necessary on at least Solaris where the /etc/rc?.d scripts
8795 are run with these signals ignored, and "SIG_IGN" settings are
8796 maintained across exec().
8797 [Rein Tollevik <reint@sys.sol.no>] PR#2009
8799 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
8800 used instead of lstat() and thus this flag didn't work as expected.
8801 [Rein Tollevik <reint@sys.sol.no>] PR#2010
8803 *) Fix the proxy pass-through feature of mod_rewrite for the case of
8804 existing QUERY_STRING now that mod_proxy was recently changed because of
8805 the new URL parsing stuff. [Ralf S. Engelschall]
8807 *) A few changes to scoreboard definitions which helps gcc generate
8808 better code. [Dean Gaudet]
8810 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
8811 be a signed bitfield. So mark a few bitfields as signed to
8812 ensure correct code. [Dean Gaudet]
8814 *) The default for HostnameLookups was changed to Off, but there
8815 was a problem and it wasn't taking effect. [Dean Gaudet]
8817 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
8820 *) After a SIGHUP the listening sockets in the parent weren't
8821 properly marked for closure on fork().
8822 [Jürgen Keil <jk@tools.de>] PR#2000
8824 *) Allow %2F in two situations: 1) it is in the query part of the URI,
8825 therefore not exposed to %2F -> '/' translations and 2) the request
8826 is a proxy request, so we're not dealing with a local resource anyway.
8827 Without this, the proxy would fail to work for any URL's with
8828 %2f in them (occurs quite often in
8829 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
8831 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
8833 *) Make the shared object compilation command more portable by avoiding
8834 the direct combination of `-c' & `-o' which is not honored by some
8835 compilers like UnixWare's cc. [Ralf S. Engelschall]
8837 *) WIN32: the proxy was creating filenames missing the last four
8838 characters. While this normally doesn't stop anything from
8839 working, it can result in extra collisions.
8840 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
8842 *) Now mod_proxy uses the response string (in addition to the response status
8843 code) from the already used FTP SIZE command to setup the Content-Length
8844 header if available. [Ralf S. Engelschall] PR#1183
8846 *) Reanimated the (still undocumented) proxy receive buffer size directive:
8847 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
8848 name was really too generic, added documentation for this directive to
8849 the mod_proxy.html and corrected the hyperlink to it in the
8850 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
8852 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
8853 faster [Martin Kraemer]
8855 *) Make Configure die when you give it an unknown command switch.
8858 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
8859 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
8860 and per default compiled support programs have manual pages - just to
8861 document our stuff a little bit more and to be able to do really
8862 Unix-like installations ;-) [Ralf S. Engelschall]
8864 *) Major cleanups to the Configure script to make it and its generated
8865 Makefiles again readable and maintainable: add SRCDIR option, removed
8866 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
8867 generated sections, consequently added Makefile headers with inheritance
8868 information, added subdir movement messages for easier following where
8869 the build process currently stays (more verbose then standard Make, less
8870 verbose than GNU make), same style to comments in the Configure script,
8871 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
8873 *) Add the new ApacheBench program "ab" to src/support/: This is derived
8874 from the ZeusBench benchmarking program and can be used to determine the
8875 response performance of an Apache installation. This version is
8876 officially licensed with Zeus Technology, Ltd. See the license agreement
8877 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
8878 [Ralf S. Engelschall]
8880 *) API: Various core functions that are definately not part of the API
8881 have been made static, and a few have been marked API_EXPORT. Still
8882 more have been marked CORE_EXPORT and are not intended for general
8883 use by modules. [Doug MacEachern, Dean Gaudet]
8885 *) mod_proxy was not clearing the Proxy-Connection header from
8886 requests; now it does. This did not violate any spec, however
8887 causes poor interactions when you are talking to remote proxies.
8888 [Marc Slemko] PR#1741
8890 *) Various cleanups to the command line interface and manual pages.
8891 [Ralf S. Engelschall]
8893 *) cfg_getline() was not properly handling lines that did not end
8894 with a line termination character. [Marc Slemko] PR#1869, 1909
8896 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
8898 *) Clean up some undocumented behavior of mod_setenvif related to
8899 "merging" two SetEnvIf directives when they match the same header
8900 and regex. Document that mod_setenvif will perform comparisons in
8901 the order they appear in the config file. Optimize mod_setenvif by
8902 doing more work at config time rather than at runtime.
8905 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
8906 to allow for modules to overrule them and to reduce redefinition
8907 warnings [Jim Jagielski]
8909 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
8912 *) Making the hard-coded cross-module function call mime_find_ct() (from
8913 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
8914 checking is really called even for proxy requests except for URLs with
8915 HTTP schemes (because there we can optimize by not running the type
8916 checking hooks due to the fact that the proxy gets the MIME Content-type
8917 from the remote host later). This change cleans up mod_mime by removing
8918 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
8919 especially unbundles mod_proxy and mod_mime. This way they both now can
8920 be compiled as shared objects and are no longer tied together.
8921 [Ralf S. Engelschall]
8923 *) util.c cleanup and speedup. [Dean Gaudet]
8925 *) API: Clarification, pstrndup() will always copy n bytes of the source
8926 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
8928 *) Mark module command_rec and handler_rec structures const so that they
8929 end up in the read-only data section (and are friendlier to systems
8930 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
8932 *) Add check to the "Port" directive to make sure the specified
8933 port is in the appropriate range. [Ben Hyde]
8935 *) Performance improvements to invoke_handler().
8936 [Dmitry Khrustalev <dima@bog.msu.su>]
8938 *) Added support for building shared objects even for library-style modules
8939 (which are built from more than one object file). This now provides the
8940 ability to build mod_proxy as a shared object module. Additionally
8941 modules like mod_example are now also supported for shared object
8942 building because the generated Makefiles now no longer assume there is at
8943 least one statically linked module. [Ralf S. Engelschall]
8945 *) API: Clarify usage of content_type, handler, content_encoding,
8946 content_language and content_languages fields in request_rec. They
8947 must always be lowercased; and the strings pointed to shouldn't
8948 be modified (you must copy them to modify them). Fix a few bugs
8949 related to this. [Dean Gaudet]
8951 *) API: Clarification: except for RAW_ARGS, all command handlers can
8952 treat the char * parameters as permanent, and modifiable. There
8953 is no need to pstrdup() them. Clean up some needless pstrdup().
8956 *) Now mod_so keeps track of which module shared objects with which names
8957 are loaded and thus avoids multiple loading and unloading and irritating
8958 error_log messages. [Ralf S. Engelschall]
8960 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
8961 environment variable in the apache core. But that tweaking interferes
8962 with mod_setenv. So don't tweak if the user has specified an explicit
8963 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
8965 *) rputs() did not calculate r->sent_bodyct properly.
8966 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
8968 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
8969 name, or left unset if this value is unavailable. Apache was setting
8970 it to the IP address when unavailable.
8971 [Tony Finch <fanf@demon.net>] PR#1925
8973 *) Various improvements to the configuration and build support for compiling
8974 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
8975 OSF1 support with GCC and vendor compilers was added. This way shared
8976 object support is now provided out-of-the-box for FreeBSD, Linux,
8977 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
8978 [Ralf S. Engelschall]
8980 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
8981 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
8982 and USE_OS2_SCOREBOARD. [Dean Gaudet]
8984 *) Fix one more special locking problem for RewriteMap programs in
8985 mod_rewrite: According to the documentation of flock(), "Locks are on
8986 files, not file descriptors. That is, file descriptors duplicated
8987 through dup(2) or fork(2) do not result in multiple instances of a lock,
8988 but rather multiple references to a single lock. If a process holding a
8989 lock on a file forks and the child explicitly unlocks the file, the
8990 parent will lose its lock.". To overcome this we have to make sure the
8991 RewriteLock file is opened _AFTER_ the childs were spawned which is now
8992 the case by opening it in the child_init instead of the module_init API
8993 hook. [Ralf S. Engelschall] PR#1029
8995 *) Change to Location and LocationMatch semantics. LocationMatch no
8996 longer lets a single slash match multiple adjacent slashes in the
8997 URL. This change is for consistency with RewriteRule and
8998 AliasMatch. Multiple slashes have meaning in URLs that they do
8999 not have in (some) filesystems. Location on the other hand can
9000 be considered a shorthand for a more complicated regex, and it
9001 does match multiple slashes with a single slash -- which is
9002 also consistent with the Alias directive.
9003 [Dean Gaudet] related PR#1440
9005 *) Fix bug with mod_mime_magic causing certain files, including files
9006 of length 0, to result in no response from the server.
9009 *) The Configure script now generates src/include/ap_config.h which
9010 contains the set of defines used when Apache is compiled on a platform.
9011 This file can then be included by external modules before including
9012 any Apache header files in case they are being built separately from
9013 Apache. Along with this change, a couple of minor changes were
9014 made to make Apache's #defines coexist peacefully with any autoconf
9015 defines an external module might have. [Rasmus Lerdorf]
9017 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9018 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9019 chance by the API to initialize its per-server configuration and thus
9020 receives the wrong one from the main server. This is now avoided by
9021 remembering the server together with the config structure while
9022 configuring and later assuming there is no config when we see a
9023 difference between the remembered server and the one calling us.
9024 [Ralf S. Engelschall] PR#1790
9026 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9027 is automatically disabled under configure time when the dbm_xxx functions
9028 are not available. Second, two heavy source code errors in the DBM
9029 support code were fixed. This makes DBM RewriteMap's usable again after
9030 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9032 *) Now all configuration files support Unix-style line-continuation via
9033 the trailing backslash ("\") character. This enables us to write down
9034 complex or just very long directives in a more readable way. The
9035 backslash character has to be really the last character before the
9036 newline and it has not been prefixed by another (escaping) backslash.

9048 *) WIN32: Preserve trailing slash in canonical path (and hence
9049 in PATH_INFO). [Paul Sutton, Ben Laurie]
9051 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
9052 depending on the rev of Solaris and what mixture of modules
9053 are in use. So it has been disabled, and Solaris is back to
9054 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9055 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9056 up static content only servers. Or it may fail unpredictably.

9059 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9062 *) API: Rewrite of absoluteURI handling, and in particular how
9063 absoluteURIs match vhosts. Unless a request is a proxy request, a
9064 "http://host" url is treated as if a similar "Host:" header had been
9065 supplied. This change was made to support future HTTP/1.x protocols
9066 which may require clients to send absoluteURIs for all requests.
9068 In order to achieve this change subtle changes were made to the API. In a
9069 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9070 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9071 by the core, modules must set it during the post_read_request or
9072 translate_names phase.
9074 Plus changes to the virtualhost test suite for absoluteURI testing.
9076 This fixes several bugs with the proxy proxying requests to vhosts
9077 managed by the same httpd.
9080 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
9081 code from mod_rewrite. The vhost matching is now performed by a
9082 globally available function matches_request_vhost(). [Dean Gaudet]

9098 *) API: A new source module main/util_uri.c; It contains a routine
9099 parse_uri_components() and friends which breaks a URI into its component
9100 parts. These parts are stored in a uri_components structure called
9101 parsed_uri within each request_rec, and are available to all modules.
9102 Additionally, an unparse routine is supplied which re-assembles the URI
9103 components back to an URI, optionally hiding the username:password@ part
9104 from ftp proxy requests, and other useful routines. Within the structure,
9105 you find on a ready-for-use basis:
9106 scheme; /* scheme ("http"/"ftp"/...) */
9107 hostinfo; /* combined [user[:password]@]host[:port] */
9108 user; /* user name, as in http://user:passwd@host:port/ */
9109 password; /* password, as in http://user:passwd@host:port/ */
9110 hostname; /* hostname from URI (or from Host: header) */
9111 port_str; /* port string (integer representation is in "port") */
9112 path; /* the request path (or "/" if only scheme://host was given) */
9113 query; /* Everything after a '?' in the path, if present */
9114 fragment; /* Trailing "#fragment" string, if present */
9115 This is meant to serve as the platform for *BIG* savings in
9116 code complexity for the proxy module (and maybe the vhost logic).
9119 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
9120 ${map:key}) available for all location where a string is created in
9121 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

9123 possible expansions are consequently usable at all string creation
9124 locations. [Ralf S. Engelschall]
9126 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
9127 and not 1) and the per-virtual-server merging of directives. Now all
9128 directives except `RewriteEngine' and `RewriteOption' are either
9129 completely overridden (default) or completely inherited (when
9130 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

9139 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
9140 (like SunOS and FreeBSD) which don't accept the locking of pipes

9161 type but with a special post-processing for the looked-up value: It
9162 parses it into alternatives according to `|' chars and then only one
9163 particular alternative is chosen randomly (this is an essential
9164 functionality needed for balancing between backend-servers when using
9165 Apache as a Reverse Proxy. The looked up value here is a list of
9166 servers). Second, `int' with the built-in maps named `tolower' and
9167 `toupper' which can be used to map URL parts to a fixed case (this is an
9168 essential feature to fix the case of server names when doing mass
9169 virtual-hosting with the help of mod_rewrite instead of using
9170 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
9171 Jay Soffian <jay@cimedia.com>] PR#1631
9173 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
9174 This directive lets Apache adjust the URL in Location-headers on HTTP
9175 redirect responses sent by the remote server. This way the virtually
9176 mapped area is no longer left on redirects and thus by-passed which is
9177 especially essential when running Apache as a reverse proxy.

9180 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
9181 hidden. [Alvaro Martinez Echevarria]
9183 *) Apache will, when started with the -X (single process) debugging flag,
9184 honor the SIGINT or SIGQUIT signals again now. This capability got lost
9185 a while ago during OS/2 signal handling changes.
9187 *) [PORT] Work around the fact that NeXT runs on more than the
9188 m68k chips in mod_status [Scott Anguish and Timothy Luoma
9191 *) [PORT] Recognize FreeBSD versions so we can use the OS regex as well
9192 as handling unsigned-chars for FreeBSD v3 and v2 [Andrey Chernov
9193 <ache@nagual.pp.ru> and Jim] PR#1450
9195 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
9196 In particular the handlers could trigger themselves into an infinite
9197 loop if RLimitMem was used with a small amount of memory -- too small
9198 for the signal stack frame to be set up. [Dean Gaudet]

9209 *) API: As Ken suggested the check_cmd_context() function and related
9210 defines are non-static now so modules can use 'em. [Martin Kraemer]
9212 *) mod_info would occasionally produce an unpaired <tt> in its
9213 output. Fixed. [Martin Kraemer]
9215 *) By default AIX binds a process (and it's children) to a single
9216 processor. httpd children now unbind themselves from that cpu
9217 and re-bind to one selected at random via bindprocessor()
9220 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
9221 effect. Work around it by using RLIMIT_AS for the RLimitMEM
9222 directive. [Enrik Berkhan <enrik@inka.de>] PR#1816
9224 *) mod_mime_magic error message should indicate the filename when
9225 reads fail. ["M.D.Parker" <mdpc@netcom.com>] PR#1827
9227 *) Previously Apache would permit </Files> to end <FilesMatch> (and
9228 similary for Location and Directory), now this is diagnosed as an
9229 error. Improve error messages for mismatched sections (<Files>,
9230 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).
9231 [Dean Gaudet, Martin Kraemer]
9233 *) <Files> is not permitted within <Location> (because of the
9234 semantic ordering). [Dean Gaudet] PR#379
9236 *) <Files> with wildcards was broken by the change in wildcard
9237 semantics (* does not match /). To fix this, <Files> now
9238 apply only to the basename of the request filename. This
9239 fixes some other inconsistencies in <Files> semantics

9247 *) Various errors from select() and accept() in child_main() would
9248 result in an infinite loop. It seems these two tickle kernel
9249 or library bugs occasionally, and result in log spammage and
9250 a generally bad scene. Now the child exits immediately,
9251 which seems to be a good workaround.

9265 Changes with Apache 1.3b5
9267 *) Source file dependencies in Makefile.tmpl files throughout the
9268 source tree were updated to accurately reflect reality.
9271 *) Preserve the content encoding given by the AddEncoding directive
9272 when the client doesn't otherwise specify an encoding.
9273 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>]
9275 *) Sort out problems with canonical filename handling happening too late.
9276 [Dean Gaudet, Ben Laurie]
9278 Changes with Apache 1.3b4
9280 *) The module structure was modified to include a *dynamic_load_handle
9281 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
9282 has been bumped accordingly. [Paul Sutton]
9284 *) All BrowserMatch directives mentioned in
9285 htdocs/manual/known_client_problems.html are in the default
9286 configuration files. [Lars Eilebrecht]
9288 *) MiNT port update. [Jan Paul Schmidt]
9290 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
9291 equivalent, similarly for x-compress and compress. Apache
9292 now ignores a leading x- when comparing encodings. It also
9293 preserves the encoding the client requests (for example if
9294 it requests x-gzip, then Apache will respond with x-gzip
9295 in the Content-Encoding header).
9296 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
9298 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
9300 *) Added mod_so module to support dynamic loading of modules on Unix
9301 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
9302 instead of AddModule in Configuration to build shared modules
9303 [Sameer Parekh, Paul Sutton]
9305 *) Minor cleanups to r->finfo handling in some modules.
9308 *) Abstract read()/write() to ap_read()/ap_write().
9309 Makes it easier to add other types of IO code such as SFIO.
9312 *) API: Generalize default_port manipulations to make support of
9313 different protocols easier. [Ben Laurie, Randy Terbush]
9315 *) There are many cases where users do not want Apache to form
9316 self-referential urls using the "canonical" ServerName and Port.
9317 The new UseCanonicalName directive (default on), if set to off
9318 will cause Apache to use the client-supplied hostname and port.
9319 API: Part of this change required a change to the construct_url()
9320 prototype; and the addition of get_server_name() and
9322 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
9323 PR#315, 459, 485, 1433
9325 *) Yet another rearrangement of the source tree.. now all the common
9326 header files are in the src/include directory. The -Imain -Iap
9327 references in Makefiles have been changed to the simpler -Iinclude
9328 instead. In addition to simplifying the build a little bit, this
9329 also makes it clear when a module is referencing something in a
9330 other than kosher manner (e.g., the proxy including mod_mime.h).
9331 Module-private header files (the proxy, mod_mime, the regex library,
9332 and mod_rewrite) have not been moved to src/include; nor have
9333 the OS-abstraction files. [Ken Coar]
9335 *) Fix a bug where r->hostname didn't have the :port stripped
9336 from it. [Dean Gaudet]
9338 *) Tweaked the headers_out table size, and the subprocess_env
9339 table size guess in rename_original_environment(). Added
9340 MAKE_TABLE_PROFILE which can help discover make_table()
9341 calls that use too small an initial guess, see alloc.c.
9344 *) Options and AllowOverride weren't properly merging in the main
9345 server setting inside vhosts (only an issue when you have no
9346 <Directory> or other section containing an Options that affects
9347 a request). Options +foo or -foo in the main_server wouldn't
9348 affect the main_server's lookup defaults. [Dean Gaudet]
9350 *) Variable 'cwd' was being used pointlessly before being set.
9353 *) r->allowed handling cleaned up in the standard modules.
9356 *) Some case-sensitivity issues cleaned up to be consistent with
9357 RFC2068. [Dean Gaudet]
9359 *) SIGURG doesn't exist everywhere.
9360 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
9362 *) mod_unique_id was erroneously generating a second unique id when
9363 an internal redirect occured. Such redirects occur, for example,
9364 when processing a DirectoryIndex match. [Dean Gaudet]
9366 *) API: table_add, table_merge, and table_set include implicit pstrdup()
9367 of the key and value. But in many cases this is not required
9368 because the key/value is a constant, or the value has been built
9369 by pstrcat() or other similar means. New routines table_addn,
9370 table_mergen, and table_setn have been added to the API, these
9371 routines do not pstrdup() their arguments. The core code and
9372 standard modules were changed to take advantage of these routines.
9373 The resulting server is up to 20% faster in some situations.
9375 Note that it is easy to get code subtly wrong if you pass a key/value
9376 which is in a pool other than the pool of the table. The only
9377 safe thing to do is to pass key/values which are in the pool of
9378 the table, or in one of the ancestors of the pool of the table.
9379 i.e. if the table is part of a subrequest, a value from the main
9380 request's pool is OK since the subrequest pool is a sub_pool of the
9381 main request's pool (and therefore has a lifespan at most as long as
9382 the main pool). There is debugging code which can detect improper
9383 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
9384 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
9386 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
9387 which don't exist on disk more gracefully; handles vhosts properly.
9388 Update documentation to reflect the code -- if there's no
9389 MimeMagicFile directive then the module is not enabled.
9392 *) PORT: Some older *nix dialects cannot automatically start scripts
9393 which begin with a #! interpreter line (the shell starts the scripts
9394 appropriately on these platforms). Apache now supports starting of
9395 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
9396 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
9399 *) API: "typedef array_header table" removed from alloc.h, folks should
9400 have been writing to use table as if it were an opaque type, but even
9401 some standard modules got this wrong. By changing the definition
9402 to "typedef struct table table" module authors will receive compile
9403 time warnings that they're doing the wrong thing. This change
9404 facilitates future changes with more sophisticated table
9405 structures. Specifically, module authors should be using table_elts()
9406 to get access to an array_header * for the table. [Dean Gaudet]
9408 *) API: Renamed new_connection() to avoid namespace collision with LDAP
9409 library routines. [Ken Coar, Rasmus Lerdorf]
9411 *) WIN32: mod_speling is now available on the Win32 platform.
9414 *) For clarity the following compile time definition was changed:
9416 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
9418 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
9419 and not be a general notice that the OS has mmap(). Now the
9420 HAVE_MMAP/SHMGET #defines strictly are informational that the
9421 OS has that method of shared memory; the type to use for
9422 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
9423 and USE_SHMGET_SCOREBOARD). This allows outside modules to
9424 determine if shared memory is available and allows Apache
9425 to determine the best method to use for the scoreboard.
9428 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
9429 as do various earlier versions. It should be safe on all versions.
9430 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
9431 the slack code. A few other cleanups for Unixware.

9434 *) PORT: A/UX can handle single-listen accepts without mutex
9435 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
9437 *) When die() happens we need to eat any request body if one exists.
9438 Otherwise we can't continue with a keepalive session. This shows up
9439 as a POST problem with MSIE 4.0, typically against pages which are
9440 authenticated. [Roy Fielding] PR#1399
9442 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
9443 header will be passed to CGIs. This is generally a security hole, so
9444 it's not a default. [Marc Slemko] PR#549
9446 *) Fix Y2K problem with date printing in suexec log.

9449 *) WIN32 deserves a pid file. [Ben Hyde]
9451 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
9453 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
9454 The choice of flock vs. fcntl was made based on timings which showed that
9455 even on non-NFS, non-exported filesystems fcntl() was an order of
9456 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
9457 that single socket users will see no difference. [Dean Gaudet] PR#467
9459 *) "File does not exist" error message was erroneously including the
9460 errno. [Marc Slemko]
9462 *) Improve the warning message generated when a client drops the
9463 connection (hits stop button, etc.) during a send. [Roy Fielding]
9465 *) Defining GPROF will disable profiling in the parent and enable it
9466 in the children. If you're profiling under Linux this is pretty much
9467 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
9469 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
9472 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
9473 gcc functionality. Work around it.

9476 *) Some linkers complain when .o files contain no functions.
9477 [Keith Severson <keith@sssd.navy.mil>] PR#1614
9479 *) Some const declarations in mod_imap.c that were added for debugging
9480 purposes caused some compilers heartburn without adding any
9481 significant value, so they've been removed. [Ken Coar]
9483 *) The src/main/*.h header files have had #ifndef wrappers added to
9484 insulate them against duplicate calls if they get included through
9485 multiple paths (e.g., in .c files as well as other .h files).
9488 *) The libap routines now have a header file for their prototypes,
9489 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
9491 *) mod_autoindex with a plaintext header file would emit the <PRE>
9492 start-tag before the HTML preamble, rather than after the preamble
9493 but before the header file contents. [John Van Essen <jve@gamers.org>]
9496 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
9497 only an issue on systems without a MAXDNAME define or where
9498 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
9500 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
9501 is used to read various types of files such as htaccess and
9502 htpasswd files. [Marc Slemko]
9504 *) SECURITY: Ensure that the buffer returned by ht_time is always
9505 properly null terminated. [Marc Slemko]
9507 *) The "Connection" header could be sent back with multiple "close"
9508 tokens. Not an error, but a waste.
9509 [Ronald.Tschalaer@psi.ch] PR#1683
9511 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
9512 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
9514 *) "basic" auth needs a case-insensitive comparison.
9515 [Ronald.Tschalaer@psi.ch] PR#1666
9517 *) For maximum portability, the environment passed to CGIs should
9518 only contain variables whose names match the regex
9519 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
9520 underscores over any character outside the regex. This
9521 affects HTTP_* variables, in a way that should be backward
9522 compatible for all the standard headers; and affects variables
9523 set with SetEnv/BrowserMatch and similar directives.
9526 *) mod_speling returned incorrect HREF's when an ambigous match
9527 was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)
9528 [robinton@amtrash.comlink.de (Soeren Ziehe), Martin Kraemer]
9530 *) PORT: Apache now compiles & runs on an EBCDIC mainframe
9531 (the Siemens BS2000/OSD family) in the POSIX subsystem
9534 *) PORT: Fix problem killing children when terminating. Allow ^C
9535 to shut down the server. [Brian Havard]
9537 *) pstrdup() is implicit in calls to table_* functions, so there's
9538 no need to do it before calling. Clean up a few cases.
9539 [Marc Slemko, Dean Gaudet]
9541 *) new -C and -c command line arguments

9559 possible buffer overflows and a possible infinite loop.
9560 [Dean Gaudet, Marc Slemko]
9562 *) SECURITY: Numerous changes to mod_imap in a general cleanup
9563 including fixing a possible buffer overflow. [Dean Gaudet]
9565 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
9566 (connections are not dropped). Code can handle graceful restarts
9567 (but there is as yet no way to signal this to Apache). Various
9568 other cleanups. [Paul Sutton]
9570 *) The aplog_error changes specific to 1.3 introduced a buffer
9571 overrun in the (now legacy) log_printf function. Fixed.
9574 *) mod_digest didn't properly deal with proxy authentication. It
9575 also lacked a case-insensitive comparision of the "Digest"

9605 alloc.c (affects win32 only). [Ben Hyde]
9607 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
9609 *) send_fd_length() did not calculate total_bytes_sent properly.
9610 [Ben Reser <breser@regnow.com>] PR#1366
9612 *) The bputc() macro was not properly integrated with the chunking
9613 code; in many cases modules using bputc() could cause completely
9614 bogus chunked output. (Typically this will show up as problems
9615 with Internet Explorer 4.0 reading a page, but other browsers
9616 having no problem.) [Dean Gaudet]
9618 *) Create LARGE_WRITE_THRESHOLD define which determines how many
9619 bytes have to be supplied to bwrite() before it will consider
9620 doing a writev() to assemble multiple buffers in one system
9621 call. This is critical for modules such as mod_include,
9622 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
9623 strings in some cases. The result would be extra effort
9624 setting up writev(), and in many cases extra effort building
9625 chunks. The default is 31, it can be overriden at compile

9641 the libap consolidation work. [Ken Coar]

9697 sometimes refer to the wrong directory. [Martin Kraemer]
9699 *) WIN32: Allocate the correct amount of memory for the scoreboard.
9702 *) WIN32: Only lowercase the part of the path that is real. [Ben Laurie]
9705 *) Fix problems with timeouts in inetd mode and -X mode. [Dean Gaudet]

9708 error messages. [Ben Hyde]
9710 Changes with Apache 1.3b3
9712 *) WIN32: Work around brain-damaged spawn calls that can't deal
9713 with spaces and slashes. [Ben Laurie]
9715 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
9716 The problem was that certain undocumented environment variables
9717 needed for sockets to work under Win32 were not being passed.
9718 [Frank Faubert <frank@sane.com>]
9720 *) Add a "-V" command line flag to the httpd binary. This
9721 flag shows some of the defines that Apache was compiled with.
9722 It is useful for debugging purposes. [Martin Kraemer]
9724 *) Start separating the ap_*() routines into their own library, so they
9725 can be used by items in src/support among other things.
9726 [Ken Coar] PR#512, 905, 1252, 1308
9728 *) Give a more informative error when no AuthType is set.
9731 *) Remove strtoul() use from mod_proxy because it isn't available
9732 on all platforms. [Marc Slemko] PR#1214
9734 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
9735 This turns out to be a bug in Winsock - select() doesn't always
9736 return the correct status. [Ben Laurie]
9738 *) Directives owned by http_core can now use the new check_cmd_context()
9739 routine to ensure that they're not being used within a container
9740 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
9742 *) PORT: Recent changes made it necessary to add explicit prototype
9743 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
9745 *) It was necessary to distinguish between resources which are
9746 allocated in the parent, for cleanup in the parent, and resources
9747 which are allocated in each child, for cleanup in each child.
9748 A new pool was created which is passed to the module child_init
9749 and child_exit functions; modules are free to register per-child
9750 cleanups there. This fixes a bug with reliable piped logs.
9753 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
9754 unless it was also doing FancyIndexes, but it displayed the
9755 HeaderName file at the top under all circumstances. It now shows
9756 the ReadmeName file for simple indices, too, as it should.
9759 *) http_core was mmap()ing even in cases where it wasn't going to
9760 read the file. [Ben Hyde <bhyde@gensym.com>]
9762 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
9763 Now the rewriting engine (the heart of mod_rewrite) is organized more
9764 straight-forward, first time well documented and reduced to the really
9765 essential parts. All redundant cases were stripped off and processing now
9766 is the same for both per-server and per-directory context with only a
9767 minimum difference (the prefix stripping in per-dir context). As a
9768 side-effect some subtle restrictions and two recently discovered problems
9769 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
9770 context and restrictions on the substitution URL on redirects.
9771 Additionally some minor source cleanups were done.

9778 *) If ap_slack fails to allocate above the low slack line it's a good

9913 server settings in <VirtualHost> blocks, flagging unhandled multiple
9914 arguments to <Directory>, <Files> etc.)

9921 *) New support tool: src/support/split-logfile, a sample Perl script which
9922 splits up a combined access log into separate files based on the
9923 name of the virtual host (listed first in the log records by "%v").
9926 Changes with Apache 1.3b2 (there is no 1.3b1)
9928 *) TestCompile was not passing $LIBS [Dean Gaudet]
9930 *) Makefile.tmpl was not using $CFLAGS in the link phase.
9933 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
9934 rudimentary memory debugger which can be used on live servers with
9935 low impact -- it sets all allocated and freed memory bytes to 0xa5.
9936 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
9937 and free() for each object. This is far more expensive and should
9938 only be used for testing with tools such as Electric Fence and
9939 Purify. See main/alloc.c for more details. [Dean Gaudet]
9941 *) Configure uses a sh trap and didn't set its exitcode properly.
9942 [Dean Gaudet] PR#1159
9944 *) Yet another vhost revamp. Add the NameVirtualHost directive which
9945 explicitly lists the ip:port pairs that are to be used for name-vhosts.
9946 From a given ip:port, regardless what the Host: header is, you can
9947 only reach the vhosts defined on that ip:port. The precedence of
9948 vhosts was reversed to match other precedences in the config --
9949 the earlier vhosts override the later vhosts. All vhost matching was
9950 moved into http_vhost.[ch]. [Dean Gaudet]
9952 *) ap_inline can be used to force inlining. GNUC __attribute__() can
9953 be used for whatever reason is appropriate (i.e. format() warnings
9954 for printf style functions). Both are enabled only with
9955 gcc >= 2.7.x (so that we have fewer support issues with older
9956 versions). [Dean Gaudet]
9958 *) Fix support for Proxy Authentication (we were testing the response
9959 status too early). [Marc Slemko]
9961 *) CoreDumpDirectory directive directs where the core file is
9962 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
9963 received. [Marc Slemko, Dean Gaudet]
9965 *) PORT: Support for Atari MINT.
9966 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
9968 *) When booting, apache will now detach itself from stdin, stdout,
9969 and stderr. stderr will not be detached until after the config
9970 files have been read so you will be able to see initial error
9971 messages. After that all errors are logged in the error_log.
9972 This makes it more convenient to start apache via rsh, ssh,
9973 or crontabs. [Dean Gaudet] PR#523
9975 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
9976 Also removed the auto-generated link to www.apache.org that was the
9977 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
9979 *) send_fb would not detect aborted connections in some situations.
9982 *) mod_include would use uninitialized data when parsing certain
9983 expressions involving && and ||. [Brian Slesinsky] PR#1139
9985 *) mod_imap should only handle GET methods. [Jay Bloodworth]
9987 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
9989 *) mod_autoindex improperly counted &escapes; as more than one
9990 character in the description. It also improperly truncated
9991 descriptions that were exactly the maximum length.
9994 *) RedirectMatch was not properly escaping the result (PR#1155). Also
9995 "RedirectMatch /advertiser/(.*) $1" is now permitted.
9998 *) mod_include now uses symbolic names to check for request success
9999 and return HTTP errors, and correctly handles all types of
10000 redirections (previously it only did temporary redirect correctly).
10001 [Ken Coar, Roy Fielding]
10003 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10004 r->filename. Since those two are meant to be in sync with each other
10005 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
10007 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
10008 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
10010 *) Inetd mode (which is buggy) uses timeouts without having setup the
10011 jmpbuffer. [Dean Gaudet] PR#1064
10013 *) Work around problem under Linux where a child will start looping
10014 reporting a select error over and over.
10015 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
10017 *) Fixed error in proxy_util.c when looping through multiple host IP
10018 addresses. [Lars Eilebrecht] PR#974
10020 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10021 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10022 bytes before writing, but it will never split a log entry across a
10023 buffer boundary. [Dean Gaudet]
10025 *) API: the short_score record has been split into two pieces, one which
10026 the parent writes on, and one which the child writes on. As part of
10027 this change the get_scoreboard_info() function was removed, and
10028 scoreboard_image was exported. This change fixes a race condition
10029 in file based scoreboard systems, and speeds up changes involving the
10030 scoreboard in earlier 1.3 development. [Dean Gaudet]
10032 *) API: New register_other_child() API (see http_main.h) which allows
10033 modules to register children with the parent for maintenance. It
10034 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10036 *) API: New piped_log API (see http_log.h) which implements piped logs,
10037 and will use register_other_child to implement reliable piped logs
10038 when it is available. The reliable piped logs part can be disabled
10039 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10040 logs is only available on Unix. [Dean Gaudet]
10042 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10043 meets_conditions(). This allows conditional HTTP selection to be
10044 handled separately from the storing of the header fields, and provides
10045 the ability for CGIs to set their own ETags for conditional checking.
10046 [Ken Coar, Roy Fielding] PR#895
10048 *) Changes to mod_log_config to allow naming of format strings.
10049 Format nicknames are defined with "LogFormat fmt nickname", and can
10050 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
10053 *) New module, "mod_speling", which can help find files even when
10054 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
10056 *) API: New function child_terminate() triggers the child process to
10057 exit, while allowing the child finish what it needs to for the
10058 current request first.
10059 [Doug MacEachern, Alexei Kosut]
10061 *) Windows now defaults to using full status reports with mod_status.
10062 [Alexei Kosut] PR #1094
10064 *) *Really* disable all mod_rewrite operations if the engine is off.
10065 Some things (like RewriteMaps) were checked/performed even if they
10066 weren't supposed to be. [Ken Coar] PR #991
10068 *) Implement a new timer scheme which eliminates the need to call alarm() all
10069 the time. Instead a counter in the scoreboard for each child is used to
10070 show when the child has made forward progress. The parent samples this
10071 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10072 progress has been made in the timeout period. This reduces the static
10073 request best-case syscall count to 22 from 29. This scheme is only
10074 used by systems with memory-based scoreboards. [Dean Gaudet]
10076 *) The proxy now properly handles CONNECT requests which are sent
10077 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10079 *) A script called apachectl has been added to the support
10080 directory. This script allows you to do things such as
10081 "apachectl start" and "apachectl restart" from the command
10082 line. [Marc Slemko]
10084 *) Modules and core routines are now put into libraries, which
10085 simplifies the link line tremendously (among other advantages).
10088 *) Some of the MD5 names defined in Apache have been renamed to have
10089 an `ap_' prefix to avoid conflicts with routines supplied by
10090 external libraries. [Ken Coar]
10092 *) Removal of mod_auth_msql.c from the distribution. There are many
10093 other options for databases today. Rather than offer one option,
10094 offer none at this time. mod_auth_msql and other SQL database
10095 authentication modules can be found at the Apache Module Registry.
10096 http://modules.apache.org/ It would be nice to offer a generic
10097 mod_auth_sql option in the near future.
10099 *) PORT: BeOS support added [Alexei Kosut]
10101 *) Configure no longer accepts the -make option, since it creates
10102 Makefile on the fly based on Makefile.tmpl and Configuration.
10104 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
10105 of forcibly killing off all its processes and exiting without
10106 cleaning up. [Alexei Kosut]
10108 *) API: A new field in the request_rec, r->mtime, has been added to
10109 avoid gratuitous parsing of date strings. It is intended to hold
10110 the last-modified date of the resource (if applicable). An
10111 update_mtime() routine has also been added to advance it if
10112 appropriate. [Roy Fielding, Ken Coar]
10114 *) SECURITY: If a htaccess file can not be read due to bad permissions,
10115 deny access to the directory with a HTTP_FORBIDDEN. The previous
10116 behavior was to ignore the htaccess file if it could not be read.
10117 This change may make some setups with unreadable htaccess files
10118 stop working. [Marc Slemko] PR#817
10120 *) Add aplog_error() providing a mechanism to define levels of
10121 verbosity to the server error logging. This addition also provides
10122 the ability to log errors using syslogd. Error logging is configurable
10123 on a per-server basis using the LogLevel directive. Conversion
10124 of log_*() in progress. [Randy Terbush]
10126 *) Further enhance aplog_error() to not log filename, line number, and
10127 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
10129 *) WIN32: Canonicalise filenames under Win32. Short filenames are
10130 converted to long ones. Backslashes are converted to forward
10131 slashes. Case is converted to lower. Parts of URLs that do not
10132 correspond to files are left completely alone. [Ben Laurie]
10134 *) PORT: 2 new OSs added to the list of ports:
10135 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
10136 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
10138 *) Add the server version (SERVER_VERSION macro) to the "server
10139 configured and running" entry in the error_log. Also build an
10140 object file at link-time that contains the current time
10141 (SERVER_BUILT global const char[]), and include that in the
10142 message. [Ken Coar]
10144 *) Set r->headers_out when sending responses from the proxy.
10145 This fixes things such as the logging of headers sent from
10146 the proxy. [Marc Slemko] PR#659
10148 *) support/httpd_monitor is no longer distributed because the
10149 scoreboard should not be file based if at all possible. Use
10150 mod_status to see current server snapshot.
10152 *) (set_file_slot): New function, allowing auth directives to be
10153 independent of the server root, so the server documents can be
10154 moved to a different directory or machine more easily.
10155 [David J. MacKenzie]
10157 *) If no TransferLog is given explicitly, decline
10158 to log. This supports coexistence with other logging modules,
10159 such as the custom one that UUNET uses. [David J. MacKenzie]
10161 *) Check for titles in server-parsed HTML files.
10162 Ignore leading newlines and returns in titles. The old behavior
10163 of replacing a newline after <title> with a space causes the
10164 title to be misaligned in the listing. [David J. MacKenzie]
10166 *) Change mod_cern_meta to be configurable on a per-directory basis.
10167 [David J. MacKenzie]
10169 *) Add 'Include' directive to allow inclusion of configuration
10170 files within configuration files. [Randy Terbush]
10172 *) Proxy errors on connect() are logged to the error_log (nothing
10173 new); now they include the IP address and port that failed
10174 (*that's* new). [Ken Coar, Marc Slemko] PR#352
10176 *) Various architectures now define USE_MMAP_FILES which causes
10177 the server to use mmap() for static files. There are two
10178 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
10179 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
10180 number of bytes written in one cycle from a single mmap()d object,
10181 default 32768). [Dean Gaudet]
10183 *) API: Added post_read_request API phase which is run right after reading
10184 the request from a client, or right after an internal redirect. It is
10185 useful for modules setting environment variables that depend only on
10186 the headers/contents of the request. It does not run during subrequests
10187 because subrequests inherit pretty much everything from the main
10188 request. [Dean Gaudet]
10190 *) Added mod_unique_id which is used to generate a unique identifier for
10191 each hit, available in the environment variable UNIQUE_ID.
10194 *) init_modules is now called after the error logs have been opened. This
10195 allows modules to emit information messages into the error logs.
10198 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10199 information for case where proxy module is not available. [Marc Slemko]
10201 *) PORT: Apache has need for mutexes to serialize its children around
10202 accept. In prior versions either fcntl file locking or flock file
10203 locking were used. The method is chosen by the definition of
10204 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
10205 and FLOCK for flock(). New options have been added:
10206 - SYSVSEM to use System V style semaphores
10207 - PTHREAD to use POSIX threads (appears to work on Solaris only)
10208 - USLOCK to use IRIX uslock
10209 Based on timing various techniques, the following changes were made
10211 - Linux 2.x uses flock instead of fcntl
10212 - Solaris 2.x uses pthreads
10213 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
10214 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT

10216 Martijn Koster <m.koster@pobox.com>]
10218 *) PORT: The semantics of accept/select make it very desirable to use
10219 mutexes to serialize accept when multiple Listens are in use. But
10220 in the case where only a single socket is open it is sometimes
10221 redundant to serialize accept(). Not all unixes do a good job with
10222 potentially dozens of children blocked on accept() on the same
10223 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
10224 the server will avoid serialization when listening on only one socket,
10225 and use serialization when listening on multiple sockets.
10226 [Dean Gaudet] PR#467
10228 *) Configure changes: TestLib replaced by TestCompile, which has
10229 some additional capability (such as doing a sanity check of
10230 the compiler and flags selected); the version of Solaris is now
10231 available via the #define value of SOLARIS2; IRIX n32bit libs
10232 now supported and selectable by new Configuration Rule: IRIXN32;
10233 We no longer default to -O2 optimization. [Jim Jagielski]
10235 *) Updated Configure: Configuration now uses AddModule to specify
10236 module source or binary file location, relative to src directory.
10237 Modules can be dropped into modules/extra, or in their own
10238 directory, and modules can come with a Makefile or Configure can
10239 create one. Modules can add compiler or library information to
10240 generated Makefiles. [Paul Sutton]
10242 *) Source core re-organisation: distributed modules are now in
10243 modules/standard. All other source code is in main. OS-specific
10244 code is in os/{unix,emx,win32} directories. [Paul Sutton]
10246 *) mod_browser has been removed, since it's replaced by mod_setenvif.
10249 *) Fix another long-standing bug in sub_req_lookup_file where it would
10250 happily skip past access checks on subdirectories looked up with
10251 relative paths. (It's used by mod_dir, mod_negotiation,
10252 and mod_include.) [Dean Gaudet]
10254 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
10255 N is the number of <Directory> sections, and M is the number of
10256 components in the filename of an object.
10258 To achieve this optimization the following config changes were made:
10259 - Wildcards (* and ?, not the regex forms) in <Directory>s,
10260 <Files>s, and <Location>s now treat a slash as a special
10261 character. For example "/home/*/public_html" previously would
10262 match "/home/a/andrew/public_html", now it only matches things
10263 like "/home/bob/public_html". This mimics /bin/sh behaviour.
10264 - It's possible now to use [] wildcarding in <Directory>, <Files>
10266 - Regex <Directory>s are applied after all non-regex <Directory>s.
10270 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
10271 and corrupted paths. [Dean Gaudet]
10273 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
10274 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
10275 be accessed now via backreferences $1..$9 in RewriteConds test-against
10276 strings in addition to RewriteRules subst string. Second the grouped
10277 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
10278 via backreferences %1..%9 both in following RewriteCond test-against
10279 strings and RewriteRules subst string. This provides maximum flexibility
10280 through the use of backreferences.
10281 Additionally the rewriting engine was cleaned up by putting common
10282 code to the new expand_backrefs_inbuffer() function.
10283 [Ralf S. Engelschall]
10285 *) When merging the main server's <Directory> and <Location> sections into
10286 a vhost, put the main server's first and the vhost's second. Otherwise
10287 the vhost can't override the main server. [Dean Gaudet] PR#717
10289 *) The <Directory> code would merge and re-merge the same section after
10290 a match was found, possibly causing problems with some modules.
10293 *) ip-based vhosts are stored and queried using a hashing function, which
10294 has been shown to improve performance on servers with many ip-vhosts.
10295 Some other changes had to be made to accommodate this:
10296 - the * address for vhosts now behaves like _default_
10297 - the matching process now is:
10298 - match an ip-vhost directly via hash (possibly matches main
10300 - if that fails, just pretend it matched the main server
10301 - if so far only the main server has been matched, perform
10302 name-based lookups (ServerName, ServerAlias, ServerPath)
10303 *only on name-based vhosts*
10304 - if they fail, look for _default_ vhosts
10305 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
10307 *) dbmmanage overhaul:
10308 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
10309 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
10310 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
10311 - provide better seed for rand
10312 - prompt for password as per getpass(3) (turn off echo, read from
10314 - use "newstyle" crypt based on $Config{osname} ($^O)
10315 - will not add a user if already in database, use new `update' command
10317 - added `check' command to check a users' password
10318 - added `import' command to convert existing password text-files or
10319 dbm files exported with `view'
10320 - more descriptive usage, general cleanup, 'use strict' clean, etc.
10323 *) Added psocket() which is a pool form of socket(), various places within
10324 the proxy weren't properly blocking alarms while registering the cleanup
10325 for its sockets. bclose() now uses pclose() and pclosesocket(). There
10326 was a bug where the client socket was being close()d twice due a still
10327 registered cleanup. [Dean Gaudet]
10329 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
10332 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
10333 [Jason Venner <jason@idiom.com>] PR#667
10335 *) Enable ``=""'' for RewriteCond directives to match against
10336 the empty string. This is the preferred way instead of ``^$''.
10337 [Ralf S. Engelschall]
10339 *) Fixed an infinite loop in mod_imap for references above the server root
10340 [Dean Gaudet] PR#748
10342 *) mod_proxy now has a ReceiveBufferSize directive, similar to
10343 SendBufferSize, so that the TCP window can be set appropriately
10344 for LFNs. [Phillip A. Prindeville]
10346 *) mod_browser has been replaced by the more general mod_setenvif
10347 (courtesy of Paul Sutton). BrowserMatch* directives are still
10348 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
10349 UnSetEnvIfZero directives. [Ken Coar]
10351 *) "HostnameLookups double" forces double-reverse DNS to succeed in
10352 order for remote_host to be set (for logging, or for the env var
10353 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
10356 *) mod_access overhaul:
10357 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
10358 and cidr syntax (i.e. 10.1.0.0/16). PR#762
10359 - Critical path was sped up by pre-computing a few things at config time.
10360 - The undocumented syntax "allow user-agents" was removed,
10361 the replacement is "allow from env=foobar" combined with mod_browser.
10362 - When used with hostnames it now forces a double-reverse lookup
10363 no matter what the directory settings are. This double-reverse
10364 doesn't affect any of the other routines that use the remote
10365 hostname. In particular it's still passed to CGIs and the log
10366 without the double-reverse check. Related PR#860.
10369 *) When a large bwrite() occurs (larger than the internal buffer size),
10370 while there is already something in the buffer, apache will combine
10371 the large write and the buffer into a single writev(). (This is
10372 in anticipation of using mmap() for reading files.)
10375 *) In obscure cases where a partial socket write occurred while chunking,
10376 Apache would omit the chunk header/footer on the next block. Cleaned
10377 up other bugs/inconsistencies in error conditions in buff.c. Fixed
10378 a bug where a long pause in DNS lookups could cause the last packet
10379 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
10381 *) API: Added child_exit function to module structure. This is called
10382 once per "heavy-weight process" just before a server child exit()'s
10383 e.g. when max_requests_per_child is reached, etc.
10384 [Doug MacEachern, Dean Gaudet]
10386 *) mod_include cleanup showed that handle_else was being used to handle
10387 endif. It didn't cause problems, but it was cleaned up too.
10390 *) mod_cern_meta would attempt to find meta files for the directory itself
10391 in some cases, but not in others. It now avoids it in all cases.
10394 *) mod_mime_magic would core dump if there was a decompression error.
10395 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
10397 *) PORT: some variants of DGUX require -lsocket -lnsl
10398 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
10400 *) mod_autoindex now allows sorting of FancyIndexed directory listings
10401 by the various fields (name, size, et cetera), either in ascending
10402 or descending order. Just click on the column header. [Ken Coar]
10404 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
10405 CPUs like the Alpha. Apache still stores ints in pointers, but that's
10406 the relatively safe direction. [Dean Gaudet] PR#344
10408 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
10409 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
10411 *) child_main avoids an unneeded call to select() when there is only one
10412 listening socket. [Dean Gaudet]
10414 *) In the event that the server is starved for idle servers it will
10415 spawn 1, then 2, then 4, ..., then 32 servers each second,
10416 doubling each second. It'll also give a warning in the errorlog
10417 since the most common reason for this is a poor StartServers
10418 setting. The define MAX_SPAWN_RATE can be used to raise/lower
10419 the maximum. [Dean Gaudet]
10421 *) Apache now provides an effectively unbuffered connection for
10422 CGI scripts. This means that data will be sent to the client
10423 as soon as the CGI pauses or stops output; previously, Apache would
10424 buffer the output up to a fixed buffer size before sending, which
10425 could result in the user viewing an empty page until the CGI finished
10426 or output a complete buffer. It is no longer necessary to use an
10427 "nph-" CGI to get unbuffered output. Given that most CGIs are written
10428 in a language that by default does buffering (e.g. perl) this
10429 shouldn't have a detrimental effect on performance.
10431 "nph-" CGIs, which formerly provided a direct socket to the client
10432 without any server post-processing, were not fully compatible with
10433 HTTP/1.1 or SSL support. As such they would have had to implement
10434 the transport details, such as encryption or chunking, in order
10435 to work properly in certain situations. Now, the only difference
10436 between nph and non-nph scripts is "non-parsed headers".
10437 [Dean Gaudet, Sameer Parekh, Roy Fielding]
10439 *) If a BUFF is switched from buffered to unbuffered reading the first
10440 bread() will return whatever remained in the buffer prior to the
10441 switch. [Dean Gaudet]
10443 Changes with Apache 1.3a1
10445 *) Added another Configure helper script: TestLib. It determines
10446 if a specified library exists. [Jim Jagielski]
10448 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
10449 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
10452 *) PORT: Some architectures use size_t for various lengths in network
10453 functions such as accept(), and getsockname(). The definition
10454 NET_SIZE_T is used to control this. [Dean Gaudet]
10456 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
10457 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
10458 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
10460 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
10461 [Igor N Kovalenko <infoh@mail.wplus.net>]
10463 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
10464 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
10465 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
10466 [Dean Gaudet] related PR#875
10468 *) API: Correct child_init() slot declaration from int to void, to
10469 match the init() declaration. Update mod_example to use the new

10475 *) get_client_block() returns wrong length if policy is
10476 REQUEST_CHUNKED_DECHUNK.

10486 *) AddModuleInfo directive for mod_info which allows you to annotate
10487 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
10489 *) Added NoProxy directive to avoid using ProxyRemote for selected
10490 addresses. Added ProxyDomain directive to cause unqualified
10491 names to be qualified by redirection.
10492 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
10494 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
10495 header to the remote host in the proxy. [Sameer Parekh and
10498 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
10499 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
10500 URLs, fixed rewritelog(), fixed forced response code handling on
10501 redirects from within .htaccess files, disabled pipe locking under
10502 braindead SunOS 4.1.x, allow env variables to be set even on rules with
10503 no substitution, bugfixed situations where HostnameLookups is off, made
10504 mod_rewrite more thread-safe for NT port and fixed problem when creating
10505 an empty query string via "xxx?".
10506 This update also removes the copyright of Ralf S. Engelschall,
10507 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
10508 exclusively copyrighted by the Apache Group now. This happened because
10509 the author now has gifted mod_rewrite exclusively to the Apache Group and
10510 no longer maintains an external version.
10511 [Ralf S. Engelschall]
10513 *) API: Added child_init function to module structure. This is called
10514 once per "heavy-weight process" before any requests are handled.
10515 See http_config.h for more details. [Dean Gaudet]
10517 *) Anonymous_LogEmail was logging on each subrequest.
10518 [Dean Gaudet] PR#421, 868
10520 *) API: Added is_initial_req() which tests if the request being
10521 processed is the initial request, or a subrequest.
10524 *) Extended SSI (mod_include) now handles additional relops for
10525 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
10527 *) Configure fixed to correctly propagate user-selected options and
10528 settings (such as CC and OPTIM) to Makefiles other than
10529 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
10531 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
10532 directory indices to start with the contents of the HeaderName file
10533 if there is one. If there isn't one, the behaviour is unchanged.
10534 [Ken Coar, Roy Fielding, Andrey A. Chernov]
10536 *) WIN32: Modules can now be dynamically loaded DLLs using the
10537 LoadModule/LoadFile directives. Note that module DLLs must be
10538 compiled with the multithreaded DLL version of the runtime library.
10539 [Alexei Kosut and Ben Laurie]
10541 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
10542 This allows the admin to completely remove automatic indexing
10543 from the server, while still supporting the basic functions of
10544 trailing-slash redirects and DirectoryIndex files. Note that if
10545 you're carrying over an old Configuration file and you use directory
10546 indexing then you'll want to add:
10548 Module autoindex_module mod_autoindex.o
10550 before mod_dir in your Configuration. [Dean Gaudet]
10552 *) popendir/pclosedir created to properly protect directory scanning.
10553 [Dean Gaudet] PR#525
10555 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
10556 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
10557 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
10560 *) The AccessFileName directive can now take more than one filename.
10561 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
10563 *) The new mod_mime_magic can be used to "magically" determine the type
10564 of a file if the extension is unknown. Based on the unix file(1)
10565 command. [Ian Kluft <ikluft@cisco.com>]
10567 *) We now determine and display the time spent processing a
10568 request if desired. [Jim Jagielski]
10570 *) mod_status: PID field of "dead" child slots no longer displays
10571 main httpd process's PID. [Jim Jagielski]
10573 *) Makefile.nt added - to build all the bits from the command line:
10574 nmake -f Makefile.nt
10575 Doesn't yet work properly. [Ben Laurie]
10577 *) Default text of 404 error is now "Not Found" rather than the
10578 potentially misleading "File Not Found". [Ken Coar]
10580 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
10581 for the net if we require people that actually need this data to
10582 enable it. [Linus Torvalds]
10584 *) directory_walk() is an expensive function, keep a little more state to
10585 avoid needless string counting. Add two new functions make_dirstr_parent
10586 and make_dirstr_prefix which replace all existing uses of make_dirstr.
10587 The new functions are a little less general than make_dirstr, but
10588 work more efficiently (less memory, less string counting).
10591 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
10592 to LDFLAGS) to avoid complications with lex rules in make files.
10593 [Dean Gaudet] PR#372
10595 *) run_method optimized to avoid needless scanning over NULLs in the
10596 module list. [Dean Gaudet]
10598 *) Revamp of (unix) scoreboard management code such that it avoids
10599 unnecessary traversals of the scoreboard on each hit. This is
10600 particularly important for high volume sites with a large
10601 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
10602 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
10603 httpd.h. [Dean Gaudet]
10605 *) In configurations using multiple Listen statements it was possible for
10606 busy sockets to starve other sockets of service. [Dean Gaudet]
10608 *) Added hook so standalone_main can be replaced at compile time
10609 (define STANDALONE_MAIN)
10612 *) Lowest-level read/write functions in buff.c will be replaced with
10613 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
10614 compile time. The default sfio discipline will behave as apache
10615 would without sfio compiled in.
10618 *) Enhance UserDir directive (mod_userdir) to accept a list of
10619 usernames for the 'disable' keyword, and add 'enable user...' to
10620 selectively *en*able userdirs if they're globally disabled.
10623 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
10624 will work with Netscape dbm files. (dbmmanage will probably not
10625 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
10627 *) Add a ListenBacklog directive to control the backlog parameter
10628 passed to listen(). Also change the default to 511 from 512.
10631 *) API: A new handler response DONE which informs apache that the
10632 request has been handled and it can finish off quickly, similar to
10633 how it handles errors. [Rob Hartill]
10635 *) Turn off chunked encoding after sending terminating chunk/footer
10636 so that we can't do it twice by accident. [Roy Fielding]
10638 *) mod_expire also issues Cache-Control: max-age headers.
10641 *) API: Added kill_only_once option for free_proc_chain so that it won't
10642 aggressively try to kill off specific children. For fastcgi.
10643 [Stanley Gambarin <gambarin@OpenMarket.com>]
10645 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
10647 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
10648 When used together, these cause mod_dir to emit HEIGHT and WIDTH
10649 attributes in the FancyIndexing IMG tags. [Ken Coar]
10651 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
10653 *) PORT: Added Windows NT support

10656 Changes with Apache 1.2.6

10707 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
10709 *) It appears the "257th byte" bug (see
10710 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
10711 at the 256th byte as well. Fixed. [Dean Gaudet]
10713 *) mod_rewrite would not handle %3f properly in some situations.
10716 *) Apache could generate improperly chunked HTTP/1.1 responses when
10717 the bputc() or rputc() functions were used by modules (such as
10718 mod_include). [Dean Gaudet]

10729 Changes with Apache 1.2.5
10731 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
10732 only an issue on systems without a MAXDNAME define or where
10733 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
10735 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
10738 *) Fix core dump in the ftp proxy when reading incorrectly formatted
10739 directory listings. [Marc Slemko]
10741 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
10744 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
10745 is used to read various types of files such as htaccess and
10746 htpasswd files. [Marc Slemko]
10748 *) SECURITY: Ensure that the buffer returned by ht_time is always
10749 properly null terminated. [Marc Slemko]
10751 *) SECURITY: General mod_include cleanup, including fixing several
10752 possible buffer overflows and a possible infinite loop. This cleanup
10753 was done against 1.3 code and then backported to 1.2, the result
10754 is a large difference (due to indentation cleanup in 1.3 code).
10755 Users interested in seeing a smaller set of relevant differences
10756 should consider comparing against src/modules/standard/mod_include.c
10757 from the 1.3b3 release. Non-indentation changes to mod_include
10758 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
10760 *) SECURITY: Numerous changes to mod_imap in a general cleanup
10761 including fixing a possible buffer overflow. This cleanup also
10762 was done with 1.3 code as a basis, see the the previous note
10763 about mod_include. [Dean Gaudet]
10765 *) SECURITY: If a htaccess file can not be read due to bad
10766 permissions, deny access to the directory with a HTTP_FORBIDDEN.
10767 The previous behavior was to ignore the htaccess file if it could not
10768 be read. This change may make some setups with unreadable
10769 htaccess files stop working. PR#817 [Marc Slemko]
10771 *) SECURITY: no2slash() was O(n^2) in the length of the input.
10772 Make it O(n). This inefficiency could be used to mount a denial

10806 on this platform. [Marc Slemko]
10808 Changes with Apache 1.2.3
10810 *) The request to a remote proxy was mangled if it was generated as the
10811 result of a ProxyPass directive. URL schemes other than http:// were not
10812 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

10816 information for case where proxy module is not available. [Marc Slemko]
10818 *) Force proxy to always respond as HTTP/1.0, which it was failing to
10819 do for errors and cached responses. [Roy Fielding]
10821 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
10823 Changes with Apache 1.2.2 [not released]
10825 *) Fixed another long-standing bug in sub_req_lookup_file where it would
10826 happily skip past access checks on subdirectories looked up with relative
10827 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
10830 *) Add lockfile name to error message printed out when
10831 USE_FLOCK_SERIALIZED_ACCEPT is defined.
10834 *) Enhanced the chunking and error handling inside the buffer functions.
10835 [Dean Gaudet, Roy Fielding]
10837 *) When merging the main server's <Directory> and <Location> sections into
10838 a vhost, put the main server's first and the vhost's second. Otherwise
10839 the vhost can't override the main server. [Dean Gaudet] PR#717
10841 *) The <Directory> code would merge and re-merge the same section after
10842 a match was found, possibly causing problems with some modules.
10845 *) Fixed an infinite loop in mod_imap for references above the server root.
10846 [Dean Gaudet] PR#748
10848 *) mod_include cleanup showed that handle_else was being used to handle
10849 endif. It didn't cause problems, but it was cleaned up too.
10852 *) Last official synchronization of mod_rewrite with author version (because
10853 mod_rewrite is now directly developed by the author at the Apache Group):
10854 o added diff between mod_rewrite 3.0.6+ and 3.0.9
10855 minus WIN32/NT stuff, but plus copyright removement.

10862 - fix for rewritelog in cases where remote hostname is unknown
10863 - fixed totally damaged request_rec walk-back loop
10864 o remove static from local data and add static to global ones.
10865 o replaced ugly proxy finding stuff by simple
10866 find_linked_module("mod_proxy") call.
10867 o added missing negation char on rewritelog()

10875 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
10876 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

10878 a deficiency in the header_parse phase.

10896 under Solaris 2.x (up through 2.5.1). It has been fixed.
10897 [Dean Gaudet] PR#832
10899 *) API: In HTTP/1.1, whether or not a request message contains a body
10900 is independent of the request method and based solely on the presence
10901 of a Content-Length or Transfer-Encoding. Therefore, our default
10902 handlers need to be prepared to read a body even if they don't know
10903 what to do with it; otherwise, the body would be mistaken for the
10904 next request on a persistent connection. discard_request_body()
10905 has been added to take care of that. [Roy Fielding] PR#378
10907 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
10908 release version number, such that it always increases along the
10909 same lines as our source code branching. [Roy Fielding]
10911 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
10913 Changes with Apache 1.2.1
10915 *) SECURITY: Don't serve file system objects unless they are plain files,
10916 symlinks, or directories. This prevents local users from using pipes
10917 or named sockets to invoke programs for an extremely crude form of

10921 could contain "../" allowing a local user to "publish" any file on
10922 the system. No slashes are allowed now. [Dean Gaudet]
10924 *) SECURITY: It was possible to violate the symlink Options using mod_dir
10925 (headers, readmes, titles), mod_negotiation (type maps), or
10926 mod_cern_meta (meta files). [Dean Gaudet]
10928 *) SECURITY: Apache will refuse to run as "User root" unless
10929 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
10931 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
10932 if it contained a .htaccess disallowing symlinks. This is contrary
10933 to the rule that symlink permissions are tested with the symlink
10934 options of the parent directory. [Dean Gaudet] PR#353
10936 *) CONFIG: The LockFile directive can be used to place the serializing
10937 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
10938 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
10941 *) Request processing now retains state of whether or not the request
10942 body has been read, so that internal redirects and subrequests will
10943 not try to read it twice (and block). [Roy Fielding]

10955 handle high numbered descriptors (examples include bind, and
10956 solaris libc). On all systems apache attempts to keep all permanent
10957 descriptors above 15 (called the low slack line). Solaris users
10958 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
10959 which keeps all non-FILE * descriptors above 255. On all systems
10960 this should make supporting large numbers of vhosts with many open
10961 log files more feasible. If this causes trouble please report it,
10962 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
10963 [Dean Gaudet] various PRs

10966 log files are opened. The only known case where this can cause

11024 reading from one buffer and writing to another, at least until it has
11025 a custom timeout handler. [Roy Fielding and Petr Lampa]

11070 original request-line. [Roy Fielding]
11072 *) Test for error conditions before creating output header fields, since
11073 we don't want the error message to include those fields. Likewise,
11074 reset the content_language(s) and content_encoding of the response
11075 before generating or redirecting to an error message, since the new

11079 and 304 responses) and err_headers_out (headers sent with all responses).
11080 Avoid the overhead of copying tables if err_headers_out is empty
11081 (the usual case). [Roy Fielding]

11096 *) The method for determining PATH_INFO has been restored to the pre-1.2b
11097 (and NCSA httpd) definition wherein it was the extra path info beyond
11098 the CGI script filename. The environment variable FILEPATH_INFO has
11099 been removed, and instead we supply the original REQUEST_URI to any
11100 script that wants to be Apache-specific and needs the real URI path.
11101 This solves a problem with existing scripts that use extra path info
11102 in the ScriptAlias directive to pass options to the CGI script.
11105 *) The _default_ change in 1.2b10 will change the behaviour on configs
11106 that use multiple Listen statements for listening on multiple ports.
11107 But that change is necessary to make _default_ consistent with other
11108 forms of <VirtualHost>. It requires such configs to be modified
11109 to use <VirtualHost _default_:*>. The documentation has been
11110 updated. [Dean Gaudet] PR#530

11194 parsing of headers. If the terminating empty-line CRLF occurs starting
11195 at the 256th or 257th byte of output, then Navigator will think a normal
11196 image is invalid. We are guessing that this is because their initial
11197 read of a new request uses a 256 byte buffer. We check the bytes written
11198 so far and, if we are about to tickle the bug, we instead insert a
11199 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

11207 *) Promote per_dir_config and subprocess_env from the subrequest to the
11208 main request in mod_negotiation. In particular this fixes a bug
11209 where <Files> sections wouldn't properly apply to negotiated content.
11212 *) Fix a potential deadlock in mod_cgi script_err handling.
11213 [Ralf S. Engelschall]
11215 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
11216 [Mitchell Blank Jr]
11218 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
11219 .htaccess files because the RewriteBase was not replaced correctly.
11220 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
11221 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
11223 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
11224 1.x the settings are those of pre-1.2b8. For 2.x we include
11225 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
11226 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
11227 [Dean Gaudet] PR#336, PR#340
11229 *) Redirect did not preserve ?query_strings when present in the client's
11230 request. [Dean Gaudet]
11232 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
11234 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
11236 *) Add UnixWare compile/install instructions. [Chuck Murcko]
11238 *) Add mod_example (illustration of API techniques). [Ken Coar]
11240 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
11242 *) Improve handling of directories when filenames have spaces in them.
11245 *) For hosts with multiple IP addresses, try all additional addresses if
11246 necessary to get a connect. Fail only if hostent address list is
11247 exhausted. [Chuck Murcko]
11249 *) More signed/unsigned port fixes. [Dean Gaudet]
11251 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
11254 Changes with Apache 1.2b8
11256 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
11257 to it. [Marc Slemko]
11259 *) The addition of <Location> and <File> directives made the
11260 sub_req_lookup_simple() function bogus, so we now handle
11261 the special cases directly. [Dean Gaudet]
11263 *) We now try to log where the server is dumping core when a fatal
11264 signal is received. [Ken Coar]
11266 *) Improved lingering_close by adding a special timeout, removing the
11267 spurious log messages, removing the nonblocking settings (they
11268 are not needed with the better timeout), and adding commentary
11269 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
11270 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
11272 *) Send error messages about setsockopt failures to the server error
11273 log instead of stderr. [Roy Fielding]
11275 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
11277 *) Stopgap solution for CGI 3-second delay with server-side includes: if
11278 processing a subrequest, allocate memory from r->main->pool instead
11279 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
11280 in the middle of an SSI request. [Dean Gaudet] PR #122
11282 *) Fixed status of response when POST is received for a nonexistent URL
11283 (was sending 405, now 404) and when any method is sent with a
11284 full-URI that doesn't match the server and the server is not acting
11285 as a proxy (was sending 501, now 403). [Roy Fielding]
11287 *) Host port changed to unsigned short. [Ken Coar] PR #276
11289 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
11291 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
11293 *) Report extra info from errno with many errors that cause httpd to exit.
11294 spawn_child, popenf, and pclosef now have valid errno returns in the
11295 event of an error. Correct problems where errno was stomped on
11296 before being reported. [Dean Gaudet]
11298 *) In the proxy, if the cache filesystem was full, garbage_coll() was
11299 never called, and thus the filesystem would remain full indefinitely.
11300 We now also remove incomplete cache files left if the origin server
11301 didn't send a Content-Length header and either the client has aborted
11302 transfer or bwrite() to client has failed. [Petr Lampa]
11304 *) Fixed the handling of module and script-added header fields.
11305 Improved the interface for sending header fields and reduced
11306 the duplication of code between sending okay responses and errors.
11307 We now always send both headers_out and err_headers_out, and
11308 ensure that the server-reserved fields are not being overridden,
11309 while not overriding those that are not reserved. [Roy Fielding]
11311 *) Moved transparent content negotiation fields to err_headers_out
11312 to reflect above changes. [Petr Lampa]
11314 *) Fixed the determination of whether or not we should make the
11315 connection persistent for all of the cases where some other part
11316 of the server has already indicated that we should not. Also
11317 improved the ordering of the test so that chunked encoding will
11318 be set whenever it is desired instead of only when KeepAlive
11319 is enabled. Added persistent connection capability for most error
11320 responses (those that do not indicate a bad input stream) when
11321 accessed by an HTTP/1.1 client. [Roy Fielding]
11323 *) Added missing timeouts for sending header fields, error responses,
11324 and the last chunk of chunked encoding, each of which could have
11325 resulted in a process being stuck in write forever. Using soft_timeout
11326 requires that the sender check for an aborted connection rather than
11327 continuing after an EINTR. Timeouts that used to be initiated before
11328 send_http_header (and never killed) are now initiated only within or
11329 around the routines that actually do the sending, and not allowed to
11330 propagate above the caller. [Roy Fielding]
11332 *) mod_auth_anon required an @ or a . in the email address, not both.
11335 *) per_dir_defaults weren't set correctly until directory_walk for
11336 name-based vhosts. This fixes an obscure bug with the wrong config
11337 info being used for vhosts that share the same ip as the server.
11340 *) Improved generation of modules/Makefile to be more generic for
11341 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
11343 *) Generate makefile dependency for Configuration based on the actual
11344 name given when running the Configure process. [Dean Gaudet]
11346 *) Fixed problem with vhost error log not being set prior to
11347 initializing virtual hosts. [Dean Gaudet]
11349 *) Fixed infinite loop when a trailing slash is included after a type map
11350 file URL (extra path info). [Petr Lampa]
11352 *) Fixed server status updating of per-connection counters. [Roy Fielding]
11354 *) Add documentation for DNS issues (reliability and security), and try
11355 to explain the virtual host matching process. [Dean Gaudet]
11357 *) Try to continue gracefully by disabling the vhost if a DNS lookup
11358 fails while parsing the configuration file. [Dean Gaudet]
11360 *) Improved calls to setsockopt. [Roy Fielding]
11362 *) Negotiation changes: Don't output empty content-type in variant list;
11363 Output charset in variant list; Return sooner from handle_multi() if
11364 no variants found; Add handling of '*' wildcard in Accept-Charset.
11365 [Petr Lampa and Paul Sutton]
11367 *) Fixed overlaying of request/sub-request notes and headers in
11368 mod_negotiation. [Dean Gaudet]
11370 *) If two variants' charset quality are equal and one is the default
11371 charset (iso-8859-1), then prefer the variant that was specifically
11372 listed in Accept-Charset instead of the default. [Petr Lampa]
11374 *) Memory allocation problem in push_array() -- it would corrupt memory
11375 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
11377 *) invoke_handler() doesn't handle mime arguments in content-type
11378 [Petr Lampa] PR#160
11380 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
11383 *) Fixed problem with ErrorDocument not working for virtual hosts
11384 due to one of the performance changes in 1.2b7. [Dean Gaudet]
11386 *) Log an error message if we get a request header that is too long,
11387 since it may indicate a buffer overflow attack. [Marc Slemko]
11389 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
11390 not reject URLs without a double-slash, as per RFC2068 section 3.2.
11391 [Ken Coar] PR #146, #187
11393 *) Added table entry placeholder for new header_parser callback
11394 in all of the distributed modules. [Ken Coar] PR #191
11396 *) Allow for cgi files without the .EXE extension on them under OS/2.
11397 [Garey Smiley] PR #59
11399 *) Fixed error message when resource is not found and URL contains
11400 path info. [Petr Lampa and Dean Gaudet] PR #40
11402 *) Fixed user and server confusion over what should be a virtual host
11403 and what is the main server, resulting in access to something
11404 other than the name defined in the virtualhost directive (but
11405 with the same IP address) failing. [Dean Gaudet]
11407 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
11408 AIX; improves the redirection stuff to enable the users to generally
11409 redirect to http, https, gopher and ftp; added TIME variable for
11410 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
11411 special patterns >STRING, <STRING and =STRING to RewriteCond, which
11412 can be used in conjunction with %{TIME} or other variables to create
11413 time-dependent rewriting rules. [Ralf S. Engelschall]
11415 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
11416 Module authors may need to adjust their code for proper cleanup to take
11417 place (that is, call note_cleanups_for_fd()). This change fixes problems
11418 with file descriptors being erroneously closed when the proxy module was
11419 in use. [Ben Laurie]
11421 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
11422 initgroups() to hose the group information needed for later
11423 comparisons. [Randy Terbush]
11425 *) Remove unnecessary call to va_end() in create_argv() which
11426 caused a SEGV on some systems.
11428 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
11431 *) Clear memory allocated for listeners. [Randy Terbush]
11433 *) Improved handling of IP address as a virtualhost address and
11434 introduced "_default_" as a synonym for the default vhost config.
11435 [Dean Gaudet] PR #212
11437 Changes with Apache 1.2b7
11439 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
11441 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
11443 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
11444 - replace protocol response numbers with symbols
11445 - save variant-list into main request notes
11446 - free allocated memory from subrequests
11447 - merge notes, headers_out and err_headers_out
11449 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
11450 "HTTP/#.# ###*" to be more lenient about what we accept.
11453 *) more proxy FTP bug fixes:
11454 - Changed send_dir() to remove user/passwd from displayed URL.
11455 - Changed login error messages to be more descriptive.
11456 - remove setting of SO_DEBUG socket option
11457 - Make ftp_getrc() more lenient about multiline responses,
11458 specifically, 230 responses which don't have continuation 230-
11459 on each line). These seem to be all NT FTP servers, and while
11460 perhaps questionable, they appear to be legal by RFC 959.
11461 - Add missing kill_timeout() after transfer to user completes.
11464 *) Fixed problem where a busy server could hang when restarting
11465 after being sent a SIGHUP due to child processes not exiting.
11468 *) Modify mod_include escaping so a '\' only signifies an escaped
11469 character if the next character is one that needs
11470 escaping. [Ben Laurie]
11472 *) Eliminated possible infinite loop in mod_imap when relative URLs are
11473 used with a 'base' directive that does not have a '/' in it.
11474 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
11476 *) Reduced the default timeout from 1200 seconds to 300, and the
11477 one in the sample configfile from 400 to 300. [Marc Slemko]
11479 *) Stop vbprintf from crashing if given a NULL string pointer;
11480 print (null) instead. [Ken Coar]
11482 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
11483 [Marc Slemko and Roy Fielding]
11485 *) Fixed problem with mod_cgi-generated internal redirects trying to
11486 read the request message-body twice. [Archie Cobbs and Roy Fielding]
11488 *) Reduced timeout on lingering close, removed possibility of a blocked
11489 read causing the child to hang, and stopped logging of errors if
11490 the socket is not connected (reset by client). [Roy Fielding]
11492 *) Rearranged main child loop to remove duplication of code in
11493 select/accept and keep-alive requests, fixed several bugs regarding
11494 checking scoreboard_image for exit indication and failure to
11495 account for all success conditions and trap all error conditions,
11496 prevented multiple flushes before closing the socket; close the entire
11497 socket buffer instead of just one descriptor, prevent logging of
11498 EPROTO and ECONNABORTED on platforms where supported, and generally
11499 improved readability. [Roy Fielding]
11501 *) Extensive performance improvements. Cleaned up inefficient use of
11502 auto initializers, multiple is_matchexp calls on a static string,
11503 and excessive merging of response_code_strings. [Dean Gaudet]
11505 *) Added double-buffering to mod_include to improve performance on
11506 server-side includes. [Marc Slemko]
11508 *) Several fixes for suexec wrapper. [Randy Terbush]
11509 - Make wrapper work for files on NFS filesystem.
11510 - Fix portability problem of MAXPATHLEN.
11511 - Fix array overrun problem in clean_env().
11512 - Fix allocation of PATH environment variable
11514 *) Removed extraneous blank line is description of mod_status chars.
11517 *) Logging of errors from the call_exec routine simply went nowhere,
11518 since the logfile fd has been closed, so now we send them to stderr.
11519 [Harald T. Alvestrand]
11521 *) Fixed core dump when DocumentRoot is a CGI.
11522 [Ben Laurie, reported by geddis@tesserae.com]
11524 *) Fixed potential file descriptor leak in mod_asis; updated it and
11525 http_core to use pfopen/pfclose instead of fopen/fclose.
11526 [Randy Terbush and Roy Fielding]
11528 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
11529 as the DEC Alpha which is 64-bit but uses 32-bit ints.
11530 [Dean Gaudet and Ken Coar]
11532 *) Return a 302 response code to the client when sending a redirect
11533 due to a missing trailing '/' on a directory instead of a 301; now
11534 it is cacheable. [Markus Gyger]
11536 *) Fix condition where, if a bad directive occurs in .htaccess, and
11537 sub_request() goes first to this directory, then log_reason() will
11538 SIGSEGV because it doesn't have initialized r->per_dir_config.
11539 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
11541 *) Fix handling of lang_index in is_variant_better(). This was
11542 causing problems which resulted in the server sending the
11543 wrong language document in some cases. [Petr Lampa]
11545 *) Remove free() from clean_env() in suexec wrapper. This was nuking
11546 the clean environment on some systems.
11548 *) Tweak byteserving code (e.g. serving PDF files) to work around
11549 bugs in Netscape Navigator and Microsoft Internet Explorer.
11550 Emit Content-Length header when sending multipart/byteranges.
11553 *) Port to HI-UX/WE2. [Nick Maclaren]
11555 *) Port to HP MPE operating system for HP 3000 machines
11556 [Mark Bixby <markb@cccd.edu>]
11558 *) Fixed bug which caused a segmentation fault if only one argument
11559 given to RLimit* directives. [Ed Korthof]
11561 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
11563 *) Improved buffered output to the client by delaying the flush decision
11564 until the BUFF code is actually about to read the next request.
11565 This fixes a problem introduced in 1.2b5 with clients that send
11566 an extra CRLF after a POST request. Also improved chunked output
11567 performance by combining writes using writev() and removing as
11568 many bflush() calls as possible. NOTE: Platforms without writev()
11569 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
11570 or Configure, unless we have already done so. [Dean Gaudet]
11572 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
11574 *) Fixed mod_info output corruption bug introduced by buffer overflow
11575 fixes. [Dean Gaudet]
11577 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
11578 for the special case of a 304 response. [Paul Sutton]
11580 *) Improved handling of TRACE method by bypassing normal method handling
11581 and header parsing routines; fixed Allow response to always allow TRACE.
11584 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
11586 *) Cleaned-up some of the generated HTML. [Ken Coar]
11588 Changes with Apache 1.2b6
11590 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
11592 *) Fix typo introduced in fix for potential infinite loop around
11593 accept() in child_main(). This change caused the rev to 1.2b6.
11594 1.2b5 was never a public beta.
11596 Changes with Apache 1.2b5
11598 *) Change KeepAlive semantics (On|Off instead of a number), add
11599 MaxKeepAliveRequests directive. [Alexei Kosut]
11601 *) Various NeXT compilation patches, as well as a change in
11602 regex/regcomp.c since that file also used a NEXT define.
11605 *) Allow * to terminate the end of a directory match in mod_dir.
11606 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
11608 *) Don't call can_exec() if suexec_enabled. Calling this requires
11609 scripts executed by the suexec wrapper to be world executable, which
11610 defeats one of the advantages of running the wrapper. [Randy Terbush]
11612 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
11615 *) Migration from sprintf() to snprintf() to avoid buffer
11616 overflows. [Marc Slemko]
11618 *) Provide portable snprintf() implementation (ap_snprintf)
11619 as well as *cvt family. [Jim Jagielski]
11621 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
11624 *) Remove mod_fastcgi.c from the distribution. This module appears
11625 to be maintained more through the Open Market channels and should
11626 continue to be easily available at http://www.fastcgi.com/
11628 *) Fixed bug in modules/Makefile that wouldn't allow building in more
11629 than one subdirectory (or cleaning, either). [Jeremy Laidman]
11631 *) mod_info assumed that the config files were relative to ServerRoot.
11634 *) CGI scripts called as an error document resulting from failed
11635 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
11637 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
11640 *) Properly check errno to prevent display of a directory index
11641 when server receives a long enough URL to confuse stat().
11644 *) Several security enhancements to suexec wrapper. It is _highly_
11645 recommended that previously installed versions of the wrapper
11646 be replaced with this version. [Randy Terbush, Jason Dour]
11648 - ~user execution now properly restricted to ~user's home
11649 directory and below.
11650 - execution restricted to UID/GID > 100
11651 - restrict passed environment to known variables
11652 - call setgid() before initgroups() (portability fix)
11653 - remove use of setenv() (portability fix)
11655 *) Add HTTP/1.0 response forcing. [Ben Laurie]
11657 *) Add access control via environment variables. [Ben Laurie]
11659 *) Add rflush() function. [Alexei Kosut]
11661 *) remove duplicate pcalloc() call in new_connection().
11663 *) Fix incorrect comparison which could allow number of children =
11664 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
11665 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
11667 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
11668 AIX PS/2, CONVEXOS. [Jim Jagielski]
11670 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
11671 It's more portable. [Martin Kraemer]
11673 *) Replace references to make in Makefile.tmpl with $(MAKE).
11676 *) Add ProxyBlock directive w/IP address caching. Add IP address
11677 caching to NoCache directive as well. ProxyBlock works with all
11678 handlers; NoCache now also works with FTP for anonymous logins.
11679 Still more code cleanup. [Chuck Murcko]
11681 *) Add "header parse" API hook [Ben Laurie]
11683 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
11685 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
11687 *) Correctly allow access and auth directives in <Files> sections in
11688 server config files. [Alexei Kosut]
11690 *) Fix bug with ServerPath that could cause certain files to be not
11691 found by the server. [Alexei Kosut]
11693 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
11694 double-quote from text and so that it properly checks for unsupported
11695 status codes using the new index_of_response interface. [Roy Fielding]
11697 *) Multiple fixes to the lingering_close code in order to avoid being
11698 interrupted by a stray timeout, to avoid lingering on a connection
11699 that has already been aborted or never really existed, to ensure that
11700 we stop lingering as soon as any error condition is received, and to
11701 prevent being stuck indefinitely if the read blocks. Also improves
11702 reporting of error conditions. [Marc Slemko and Roy Fielding]
11704 *) Fixed initialization of parameter structure for sigaction.
11705 [mgyger@itr.ch, Adrian Filipi-Martin]
11707 *) Fixed reinitializing the parameters before each call to accept and
11708 select, and removed potential for infinite loop in accept.
11709 [Roy Fielding, after useful PR from adrian@virginia.edu]
11711 *) Fixed condition where, if a child fails to fork, the scoreboard would
11712 continue to say SERVER_STARTING forever. Eventually, the main process
11713 would refuse to start new children because count_idle_servers() will
11714 count those SERVER_STARTING entries and will always report that there
11715 are enough idle servers. [Phillip Vandry]
11717 *) Fixed bug in bcwrite regarding failure to account for partial writes.
11718 Avoided calling bflush() when the client is pipelining requests.
11719 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
11721 *) Added description of "." mode in server-status [Jim Jagielski]
11723 Changes with Apache 1.2b4
11725 *) Fix possible race condition in accept_mutex_init() that
11726 could leave a small security hole open allowing files to be
11727 overwritten in cases where the server UID has write permissions.
11730 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
11732 *) Fix portablity problem in util_script where ARG_MAX may not be
11733 defined for some systems.
11735 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
11738 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
11739 style magic #! token for better script portability. [Garey Smiley]
11741 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
11742 execution for ~userdir CGI. [Jason Dour]
11744 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
11746 *) Fix month off by one in suexec wrapper logging.
11748 Changes with Apache 1.2b3:
11750 *) Fix error in mod_cgi which could cause resources not to be properly
11751 freed, or worse. [Dean Gaudet]
11753 *) Fix find_string() NULL pointer dereference. [Howard Fear]
11755 *) Add set_flag_slot() at the request of Dirk and others.
11758 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
11760 *) Add changes to improve the error message given for invalid
11761 ServerName parameters. [Dirk vanGulik]
11763 *) Add "Authoritative" directive for Auth modules that don't
11764 currently have it. This gives admin control to assign authoritative
11765 control to an authentication scheme and allow "fall through" for
11766 those authentication modules that aren't "Authoritative" thereby
11767 allowing multiple authentication mechanisms to be chained.
11770 *) Remove requirement for ResourceConfig/AccessConfig if not using
11771 the three config file layout. [Randy Terbush]
11773 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
11775 *) Changes to suexec wrapper to fix the following problems:
11776 1. symlinked homedirs will kill ~userdirs.
11777 2. initgroups() on Linux 2.0.x clobbers gr->grid.
11778 3. CGI command lines paramters problems
11779 4. pw-pwdir for "docroot check" still the httpd user's pw record.
11780 [Randy Terbush, Jason Dour]
11782 *) Change create_argv() to accept variable arguments. This fixes
11783 a problem where arguments were not getting passed to the CGI via
11784 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
11786 *) Collapse multiple slashes in path URLs to properly apply
11787 handlers defined by <Location>. [Alexei Kosut]
11789 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
11791 *) Improve the accuracy of request duration timings by setting
11792 r->request_time in read_request_line() instead of read_request().
11795 *) Reset timeout while reading via get_client_block() in mod_cgi.c
11796 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
11798 *) Add the ability to pass different Makefile.tmpl files to Configure
11799 using the -make flag. [Rob Hartill]
11801 *) Fix coredump triggered when sending a SIGHUP to the server caused
11802 by an assertion failure, in turn caused by an uninitialised field in a
11806 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
11807 PATH_INFO from previous versions of Apache (in certain situations,
11808 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
11809 [later removed in 1.2b11]
11811 *) Add rwrite() function to API to allow for sending strings of
11812 arbitrary length. [Doug MacEachern]
11814 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
11816 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
11817 NeXT. [Jim Jagielski]
11819 *) Removed recent modification to promote the status code on internal
11820 redirects, since the correct fix was to change the default log format
11821 in mod_log_config so that it outputs the original status. [Rob Hartill]
11823 Changes with Apache 1.2b2:
11825 *) Update set_signals() to use sigaction() for setting handlers.
11826 This appears to fix a re-entrant problem in the seg_fault()
11827 bus_error() handlers. [Randy Terbush]
11829 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
11831 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
11833 *) proxy_http.c bugfixes: [Chuck Murcko]
11834 1) fixes possible NULL pointer reference w/NoCache
11835 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
11836 host would cache nothing if it was in the local domain,
11837 and the local domain was in the NoCache list)
11838 3) Adds Host: header when not available
11839 4) Some code cleanup and clarification
11841 *) mod_include.c bugfixes:
11842 1) Fixed an ommission that caused include variables to not
11843 be parsed in config errmsg directives [Howard Fear]
11844 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
11845 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
11846 4) Allow backslash-escaping to all quoted text
11847 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
11848 5) Pass variable to command line if not set in XSSI's env
11851 *) Fix infinite loop when processing Content-language lines in
11852 type-map files. [Alexei Kosut]
11854 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
11856 *) Fixed problem in set_[user|group] that prevented CGI execution
11857 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
11859 *) Added PORTING information file. [Jim Jagielski]
11861 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
11863 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
11865 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
11866 USE_FCNTL_SERIALIZED_ACCEPT was intended.
11868 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
11869 which caused problems of systems where socket s_addr is >32bits.
11871 *) Added comment to explain (r->chunked = 1) side-effect in
11872 http_protocol.c [Roy Fielding]
11874 *) Replaced use of index() in mod_expires.c with more appropriate
11875 and portable isdigit() test. [Ben Laurie]
11877 *) Updated Configure for ...
11878 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
11879 *-dg-dgux* (bad pattern match)
11880 QNX (DEF_WANTHSREGEX=yes)
11881 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
11883 *-unixware211 (new)
11884 and added some user diagnostic info. [Ben Laurie]
11886 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
11887 for better portability. [Jim Jagielski]
11889 *) Updated helpers/GuessOS for ...
11890 SCO 5 (recognize minor releases)
11891 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
11892 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
11893 IRIX64 (-sgi-irix64)
11894 ULTRIX (-unknown-ultrix)
11895 SINIX (-whatever-sysv4)
11896 NCR Unix (-ncr-sysv4)
11897 and fixed something in helpers/PrintPath [Ben Laurie]
11899 Changes with Apache 1.2b1
11901 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
11903 Changes with Apache 1.1.1
11905 *) Fixed bug where Cookie module would make two entries in the
11906 logfile for each access [Mark Cox]
11908 *) Fixed bug where Redirect in .htaccess files would cause memory
11909 leak. [Nathan Neulinger]
11911 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
11913 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
11915 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
11917 Changes with Apache 1.1.0
11919 *) Bring NeXT support up to date. [Takaaki Matsumoto]
11921 *) Bring QNX support up to date. [Ben Laurie]
11923 *) Make virtual hosts default to main server keepalive parameters.
11924 [Alexei Kosut, Ben Laurie]
11926 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
11928 *) Fix missing address family for connect, also remove unreachable statement
11929 in mod_proxy. [Ben Laurie]
11931 *) mod_env now turned on by default in Configuration.tmpl.
11933 *) Bugs which were fixed:
11934 a) yet more mod_proxy bugs [Ben Laurie]
11935 b) CGI works again with inetd [Alexei Kosut]
11936 c) Leading colons were stripped from passwords [osm@interguide.com]
11937 d) Another fix to multi-method Limit problem [jk@tools.de]
11939 Changes with Apache 1.1b4
11941 *) r->bytes_sent variable restored. [Robert Thau]
11943 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
11945 *) More possibly unsecure programs removed from the support directory.
11947 *) More mod_auth_msql authentication improvements.
11949 *) VirtualHosts based on Host: headers no longer conflict with the
11952 *) OS/2 compatibility enhancements. [Gary Smiley]
11954 *) POST now allowed to directory index CGI scripts.
11956 *) Actions now work with files of the default type.
11958 *) Bugs which were fixed:
11959 a) more mod_proxy bugs
11960 b) early termination of inetd requests
11961 c) compile warnings on several systems
11962 d) problems when scripts stop reading output early
11964 Changes with Apache 1.1b3
11966 *) Much of cgi-bin and all of cgi-src has been removed, due to
11967 various security holes found and that we could no longer support
11970 *) The "Set-Cookie" header is now special-cased to not merge multiple
11971 instances, since certain popular browsers can not handle multiple
11972 Set-Cookie instructions in a single header. [Paul Sutton]
11974 *) rprintf() added to buffer code, occurrences of sprintf removed.
11977 *) CONNECT method for proxy module, which means tunneling SSL should work.
11978 (No crypto needed) Also a NoCache config directive.
11980 *) Several API additions: pstrndup(), table_unset() and get_token()
11981 functions now available to modules.
11983 *) mod_imap fixups, in particular Location: headers are now complete
11986 *) New "info" module which reports on installed module set through a
11987 special URL, a la mod_status.
11989 *) "ServerPath" directive added - allows for graceful transition
11990 for Host:-header-based virtual hosts.
11992 *) Anonymous authentication module improvements.
11994 *) MSQL authentication module improvements.
11996 *) Status module design improved - output now table-based. [Ben Laurie]
11998 *) htdigest utility included for use with digest authentication
12001 *) mod_negotiation: Accept values with wildcards to be treated with
12002 less priority than those without wildcards at the same quality
12003 value. [Alexei Kosut]
12005 *) Bugs which were fixed:
12006 a) numerous mod_proxy bugs
12007 b) CGI early-termination bug [Ben Laurie]
12008 c) Keepalives not working with virtual hosts
12009 d) RefererIgnore problems
12010 e) closing fd's twice in mod_include (causing core dumps on
12011 Linux and elsewhere).
12013 Changes with Apache 1.1b2
12016 a) core dumps in mod_digest
12017 b) truncated hostnames/ip address in the logs
12018 c) relative URL's in mod_imap map files
12020 Changes with Apache 1.1b1
12022 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12024 Changes with Apache 1.0.3
12026 *) Internal redirects which occur in mod_dir.c now preserve the
12027 query portion of a request (the bit after the question mark).
12030 *) Escape active characters '<', '>' and '&' in html output in
12031 directory listings, error messages and redirection links.
12034 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12036 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12039 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12041 *) Reset timeout timer after each successful fwrite() to the network.
12042 This patch adds a reset_timeout() procedure that is called by
12043 send_fd() to reset the timeout ever time data is written to the net.
12046 *) timeout() signal handler now checks for SIGPIPE and reports
12047 lost connections in a more user friendly way. [Rob Hartill]
12049 *) Location of the "scoreboard" file which used to live in /tmp is
12050 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12051 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12053 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12055 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12056 which caused a SEGV with cookies enabled
12058 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12061 *) Log the UNIX textual error returned by some system calls, in
12062 particular errors from accept() [David Robinson]
12064 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12066 Changes with Apache 1.0.2
12068 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12069 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12071 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12074 *) past changes to http_config.c to only use the
12075 setrlimit function on systems defining RLIMIT_NOFILE
12076 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12077 for SUNOS and prototypes the needed functions.
12079 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12082 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12084 *) Merge multiple headers from CGI scripts instead of taking last
12085 one. [David Robinson]
12087 *) Add support for SCO 5. [Ben Laurie]
12089 Changes with Apache 1.0.1
12091 *) Silence mod_log_referer and mod_log_agent if not configured
12094 *) Recursive includes can occur if the client supplies PATH_INFO data
12095 and the server provider uses relative links; as file.html
12096 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
12098 *) The replacement for initgroups() did not call {set,end}grent(). This
12099 had two implications: if anything else used getgrent(), then
12100 initgroups() would fail, and it was consuming a file descriptor.
12103 *) On heavily loaded servers it was possible for the scoreboard to get
12104 out of sync with reality, as a result of a race condition.
12105 The observed symptoms are far more Apaches running than should
12106 be, and heavy system loads, generally followed by catastrophic
12107 system failure. [Ben Laurie]
12109 *) Fix typo in license. [David Robinson]
12111 Changes with Apache 1.0.0 23 Nov 1995
12113 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
12115 Changes with Apache 0.8.16 05 Nov 1995
12117 *) New man page for 'httpd' added to support directory [David Robinson]
12119 *) .htgroup files can have more than one line giving members for a
12120 given group (each must have the group name in front), for NCSA
12121 back-compatibility [Robert Thau]
12123 *) Mutual exclusion around accept() is on by default for SVR4 systems
12124 generally, since they generally can't handle multiple processes in
12125 accept() on the same socket. This should cure flaky behavior on
12126 a lot of those systems. [David Robinson]
12128 *) AddType, AddEncoding, and AddLanguage directives take multiple
12129 extensions on a single command line [David Robinson]
12131 *) UserDir can be disabled for a given virtual host by saying
12132 "UserDir disabled" in the <VirtualHost> section --- it was a bug
12133 that this didn't work. [David Robinson]
12135 *) Compiles on QNX [Ben Laurie]
12137 *) Corrected parsing of ctime time format [David Robinson]
12139 *) httpd does a perror() before exiting if it can't log its pid
12140 to the PidFile, to make diagnosing the error a bit easier.
12143 *) <!--#include file="..."--> can no longer include files in the
12144 parent directory, for NCSA back-compatibility. [David Robinson]
12146 *) '~' is *not* escaped in URIs generated for directory listings
12149 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
12151 *) Fixed bug involving handling URIs with escaped %-characters
12152 in redirects [David Robinson]
12154 Changes with Apache 0.8.15 14 Oct 1995
12156 *) Switched to new, simpler license
12158 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
12160 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
12162 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
12164 *) Correctly handles internal redirects to files with names containing '%'
12167 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
12169 *) Use geteuid() rather than getuid() to see if we have root privilege,
12170 so that server correctly resets privilege if run setuid root. [Andrew
12173 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
12176 *) Fix relative URLs in imagemap files [Randy Terbush]
12178 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
12181 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
12182 entries all name the same one. [David Robinson]
12184 *) Fix directory listings with filenames containing unusual characters
12187 *) Better URI-escaping for generated URIs in directories with filenames
12188 containing unusual characters [Ben Laurie]
12190 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
12192 *) Unblock alarms on error return from spawn_child() [David Robinson]
12194 *) Sample Config files have extra note for SCO users [Ben Laurie]
12196 *) Configuration has note for HP-UX users [Rob Hartill]
12198 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
12200 *) Nuked bogus #define in httpd.h [David Robinson]
12202 *) Better test for whether a system has setrlimit() [David Robinson]
12204 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
12206 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
12209 Changes with Apache 0.8.14 19 Sep 1995
12211 *) Compiles on SCO ODT 3.0 [Ben Laurie]
12213 *) AddDescription works (better) [Ben Laurie]
12215 *) Leaves an intelligible error diagnostic when it can't set group
12216 privileges on standalone startup [Andrew Wilson]
12218 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
12219 that machine, which claims to be BSD but does not support RLIMIT.
12222 *) gcc -Wall no longer complains about an unused variable when util.c
12223 is compiled with -DMINIMAL_DNS [Andrew Wilson]
12225 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
12227 Changes with Apache 0.8.13 07 Sep 1995
12229 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
12231 *) Have built-in imagemap code recognize & honor Point directive [James
12234 *) Generate cleaner directory listings in directories with a mix of
12235 long and short filenames [Rob Hartill]
12237 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
12239 *) Properly default ServerName for virtual servers [Robert Thau]
12241 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
12242 Paul Richards and a cast of thousands...]
12244 *) On self-identified BSD systems (we don't try to guess any more),
12245 allocate a few extra file descriptors per virtual host with setrlimit,
12246 if we can, to avoid running out. [Randy Terbush]
12248 *) Write 22-character lock file name into buffer with enough space
12249 on startup [Konstantin Olchanski]
12251 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
12254 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
12256 *) Suppress -Wall warning by initializing variable in negotiation code
12257 [Tobias Weingartner]
12259 Changes with Apache 0.8.12 31 Aug 1995
12261 *) Doesn't pause three seconds after including a CGI script which is
12262 too slow to die off (this is done by not even trying to kill off
12263 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
12264 after the entire document has been processed). [Robert Thau]
12266 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
12268 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
12270 *) Allows .htaccess files to override <Directory> sections naming the
12271 same directory [David Robinson]
12273 *) Removed an efficiency hack in sub_req_lookup_uri which was
12274 causing certain extremely marginal cases (e.g., ScriptAlias of a
12275 *particular* index.html file) to fail. [David Robinson]
12277 *) Doesn't log an error when the requested URI requires
12278 authentication, but no auth header line was supplied by the
12279 client; this is a normal condition (the client doesn't no auth is
12280 needed here yet). [Robert Thau]
12282 *) Behaves more sanely when the name server loses its mind [Sean Welch]
12284 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
12286 *) RFC931 code no longer passes out name of prior clients on current
12287 requests if the current request came from a server that doesn't
12288 do RFC931. [David Robinson]
12290 *) Configuration script accepts "Module" lines with trailing whitespace.
12293 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
12295 *) Cleaned up comments in mod_cgi.c [Robert Thau]
12297 Changes with Apache 0.8.11 24 Aug 1995
12299 *) Wildcard <Directory> specifications work. [Robert Thau]
12301 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
12303 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
12304 the file being requested itself, in addition to the directories leading
12305 up to it. [Robert Thau]
12307 *) Logs access failures due to symlink checks or invalid client address
12308 in the error log [Roy Fielding, Robert Thau]
12310 *) Symlink checks deal correctly with systems where lstat of
12311 "/path/to/some/link/" follows the link. [Thau, Fielding]
12313 *) Doesn't reset DirectoryIndex to 'index.html' when
12314 other directory options are set in a .htaccess file. [Robert Thau]
12316 *) Clarified init code and nuked bogus warning in mod_access.c
12317 [Florent Guillaume]
12319 *) Corrected several directives in sample srm.conf
12320 --- includes corrections to directory indexing icon-related directives
12321 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
12322 icons for encodings right, and turning on AddEncoding by default).
12325 *) Corrected descriptions of args to AddIcon and AddAlt in command table
12328 *) INSTALL & README mention "contributed modules" directory [Brian
12331 *) Fixed English in the license language... "for for" --> "for".
12334 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
12335 mod_alias.c, merging it almost completely with handling of Alias, and
12336 adding a 'notes' field to the request_rec which allows the CGI module
12337 to discover whether the Alias module has put this request through
12338 ScriptAlias (which it needs to know for back-compatibility, as the old
12339 NCSA code did not check Options ExecCGI in ScriptAlias directories).
12342 Changes with Apache 0.8.10 18 Aug 1995
12344 *) AllowOverride applies to the named directory, and not just
12345 subdirectories. [David Robinson]
12347 *) Do locking for accept() exclusion (on systems that need it)
12348 using a special file created for the purpose in /usr/tmp, and
12349 not the error log; using the error log causes real problems
12350 if it's NFS-mounted; this is known to be the cause of a whole
12351 lot of "server hang" problems with Solaris. [David Robinson;
12352 thanks to Merten Schumann for help diagnosing the problem].
12354 Changes with Apache 0.8.9 12 Aug 1995
12356 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
12358 *) Nested includes see environment variables of the including document,
12359 for NCSA bug-compatibility (some sites have standard footer includes
12360 which try to print out the last-modified date). [Eric Hagberg/Robert
12363 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
12364 URI as a CGI script, even if it would have been treated as something
12365 else if requested directly, for NCSA back-compatibility. (Note that
12366 this means that people who know the name of the script can see the
12367 code just by asking for it). [Robert Thau]
12369 *) New version of dbmmanage script included in support directory as
12372 *) Check if scoreboard file couldn't be opened, and say so, rather
12373 then going insane [David Robinson]
12375 *) POST to CGI works on A/UX [Jim Jagielski]
12377 *) AddIcon and AddAlt commands work properly [Rob Hartill]
12379 *) NCSA server push works properly --- the Arena bug compatibility
12380 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
12381 if you still want the workaround). [Rob Hartill]
12383 *) If client didn't submit any Accept-encodings, ignore encodings in
12384 content negotiation. (NB this will all have to be reworked anyway
12385 for the new HTTP draft). [Florent Guillaume]
12387 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
12389 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
12391 *) Give Redirect priority over Alias, for NCSA bug compatibility
12394 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
12395 paralleling earlier bug fix for CGI [David Robinson]
12397 *) If DBM auth is improperly configured, report a server error and don't
12400 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
12401 it seems to work well enough without it (even in a 10 hits/sec
12402 workout), and the overhead for the locking under A/UX is
12403 alarmingly high (though it is very low on other systems).
12404 [Eric Hagberg, Jim Jagielski]
12406 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
12408 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
12409 Behlendorf/Eric Hagberg]
12411 *) More improvements to default Configuration for A/UX [Jim Jagielski]
12413 *) Compiles clean on NEXT [Rob Hartill]
12415 *) Compiles clean on SGI [Robert Thau]
12417 Changes with Apache 0.8.8 08 Aug 1995
12419 *) SunOS library prototypes now never included unless explicitly
12420 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
12421 people using GNU libc on SunOS are screwed by prototypes for the
12424 (Those who wish to compile clean with gcc -Wall on a standard
12425 SunOS setup need the prototypes, and may obtain them using
12426 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
12427 with nonstandard libraries are presumably competent to make their
12430 *) Strips trailing '/' characters off both args to the Alias command,
12431 to make 'Alias /foo/ /bar/' work.
12433 Changes with Apache 0.8.7 03 Aug 1995
12435 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
12436 [reported by David Robinson]
12438 *) Compiles clean on OSF/1 [David Robinson]
12440 *) Added some of the more recent significant changes (AddLanguage stuff,
12441 experimental LogFormat support) to CHANGES file in distribution root
12444 Changes with Apache 0.8.6 02 Aug 1995
12446 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
12447 (If you actually wanted a conditional GET which bypassed the cache, you
12448 couldn't get it). [Reported by Roy Fielding]
12450 *) Properly terminate headers on '304 Not Modified' replies to conditional
12451 GETs --- no browser we can find cares much, but the CERN proxy chokes.
12452 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
12454 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
12456 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
12457 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
12458 and older versions don't set the __SUNPRO_C preprocessor variable). On
12459 all other systems, these are never used anyway. [Reported by Mark Cox].
12461 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
12463 Changes with Apache 0.8.5 01 Aug 1995
12465 *) Added last-minute configurable log experiment, as optional module
12467 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
12468 properly. (One-line fix to http_protocol.c).
12470 *) Work around bogus behavior when reloading from Netscape.
12471 It's Netscape's bug --- for some reason they expect a request with
12472 If-modified-since: to not function as a conditional GET if it also
12473 comes with Pragma: no-cache, which is way out of line with the HTTP
12474 spec (according to Roy Fielding, the redactor).
12476 *) Added parameter to set maximum number of server processes.
12478 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
12481 *) IdentityCheck bugfix [Chuck Murcko].
12483 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
12485 *) More sample config file corrections; add extension to AddType for
12486 *.asis, move AddType generic description to its proper place, and
12487 fix miscellaneous typos. [ Alexei Kosut ]
12489 *) Deleted the *other* reference to the regents from the Berkeley
12490 legal disclaimer (everyplace).
12492 *) Nuked Shambhala name from src/README; had already cleaned it out
12493 of everywhere else.
12495 Changes with Apache 0.8.4
12497 *) Changes to server-pool management parms --- renamed current
12498 StartServers to MinSpareServers, created separate StartServers
12499 parameter which means what it says, and renamed MaxServers to
12500 MaxSpareServers (though the old name still works, for NCSA 1.4
12501 back-compatibility). The old names were generally regarded as
12502 too confusing. Also altered "docs" in sample config files.
12504 *) More improvements to default config files ---
12505 sample directives (commented out) for XBitHack, BindAddress,
12506 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
12507 defaults, AddTypes for send-as-is and imagemap magic types, and
12508 improvements to samples for DirectoryIndex [Alexei Kosut]
12510 *) Yet more improvements to default config files --- changes to
12511 Alexei's sample AddLanguage directives, and sample LanguagePriority
12512 [ Florent Guillaume ]
12514 *) Set config file locations properly if not set in httpd.conf
12517 *) Don't escape URIs in internal redirects multiple times; don't
12518 do that when translating PATH_INFO to PATH_TRANSLATED either.
12521 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
12523 Changes with Apache 0.8.3
12525 *) Edited distribution README to *briefly* summarize installation
12526 procedures, and give a pointer to the INSTALL file in the src/
12529 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
12530 recent NCSA distributions.
12532 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
12533 exist for the same directory, use both and don't segfault. [Reported
12536 *) Proper makefile dependencies [David Robinson]
12538 *) Note (re)starts in error log --- reported by Rob Hartill.
12540 *) Only call no2slash() after get_path_info() has been done, to
12541 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
12542 reported by Andrew Wilson, though this one is probably a real bug]
12544 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
12545 dump core when Referer is not supplied. [Randy Terbush]
12547 *) Lightly edited sample config files to refer people to our documentation
12548 instead of NCSA's, and to list Rob McCool as *original* author (also
12549 deleted his old, and no doubt non-functional email address). Would be
12550 nice to have examples of new features...
12552 Changes with Apache 0.8.2 19 Jul 1995
12554 *) Added AddLanuage code [Florent Guillaume]
12556 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
12558 *) All sorts of problems when MultiViews finds a directory. It would
12559 be nice if mod_dir.c was robust enough to handle that, but for now,
12560 just punt. [reported by Brian Behlendorf]
12562 *) Wait for all children on restart, to make sure that the old socket
12563 is gone and we can reopen it. [reported by Randy Terbush]
12565 *) Imagemap module is enabled in default Configuration
12567 *) RefererLog and UserAgentLog modules properly default the logfile
12570 *) Mark Cox's mod_cookies added to the distribution as an optional
12571 module (commented out in the default Configuration, and noted as
12572 an experiment, along with mod_dld). [Mark Cox]
12574 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
12576 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
12578 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
12580 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
12583 Changes with Apache 0.8.1
12585 *) New imagemap module [Randy Terbush]
12587 *) Replacement referer log module with NCSA-compatible RefererIgnore
12588 [Matthew Gray again]
12590 *) Don't mung directory listings with very long filenames.
12591 [Florent Guillaume]
12593 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
12595 *) New config script. See INSTALL for info. [Robert Thau]
12597 *) Scoreboard mechanism for regulating the number of extant server
12598 processes. MaxServers and StartServers defaults are the same as
12599 for NCSA, but the meanings are slightly different. (Actually,
12600 I should probably lower the MaxServers default to 10).
12602 Before asking for a new connection, each server process checks
12603 the number of other servers which are also waiting for a
12604 connection. If there are more than MaxServers, it quietly dies
12605 off. Conversely, every second, the root, or caretaker, process
12606 looks to see how many servers are waiting for a new connection;
12607 if there are fewer than StartServers, it starts a new one. This
12608 does not depend on the number of server processes already extant.
12609 The accounting is arranged through a "scoreboard" file, named
12610 /tmp/htstatus.*, on which each process has an independent file
12611 descriptor (they need to seek without interference).
12613 The end effect is that MaxServers is the maximum number of
12614 servers on an *inactive* server machine, but more will be forked
12615 off to handle unusually heavy loads (or unusually slow clients);
12616 these will die off when they are no longer needed --- without
12617 reverting to the overhead of full forking operation. There is a
12618 hard maximum of 150 server processes compiled in, largely to
12619 avoid forking out of control and dragging the machine down.
12620 (This is arguably too high).
12622 In my server endurance tests, this mechanism did not appear to
12623 impose any significant overhead, even after I forced it to put the
12624 scoreboard file on a normal filesystem (which might have more
12625 overhead than tmpfs). [Robert Thau]
12627 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
12630 *) Read .htaccess files even in directory with <Directory> section.
12631 (Former incompatibility noted on mailing list, now fixed). [Robert
12634 *) "HEAD /" gives the client a "Bad Request" error message, rather
12635 than trying to send no body *and* no headers. [Cliff Skolnick].
12637 *) Don't produce double error reports for some very obscure cases
12638 mainly involving auth configuration (the "all modules decline to
12639 handle" case which is a sure sign of a server bug in most cases,
12640 but also happens when authentication is badly misconfigured).
12643 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
12644 it's *for*, and this sort of thing really shouldn't be cluttering
12645 up the Makefile). [Robert Thau]
12647 *) Incidental code cleanups in http_main.c --- stop dragging
12648 sa_client around; just declare it where used. [Robert Thau]
12650 *) Another acc-related fix. (It doesn't like const char
12651 in some places...). [Mark Cox]
12653 Changes with Shambhala 0.6.1 13 Jul 1995
12655 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
12656 Also, fixed auth typo in http_protocol.c unmasked by this fix.
12658 *) Compiles clean with acc on SunOS [Paul Sutton]
12660 *) Reordered modules in modules.c so that Redirect takes priority
12661 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
12662 believe it or not, he has an actual site with a ScriptAlias and
12663 a Redirect declared for the *exact same directory*. Even *my*
12664 compatibility fetish wouldn't motivate me to fix this if the fix
12665 required any effort, but it doesn't, so what the hey.
12667 *) Fixed to properly default several server_rec fields for virtual
12668 servers from the corresponding fields in the main server_rec.
12669 [Cliff Skolnick --- 'port' was a particular irritant].
12671 *) No longer kills off nph- child processes before they are
12672 finished sending output. [Matthew Gray]
12674 Changes with Shambhala 0.6.0 10 Jul 1995
12676 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
12677 the connection to the client in an "aborted" state, but otherwise
12678 allow whatever handlers are running to clean up. hard_timeout()s
12679 abort the request in progress completely; anything not tied to some
12680 resource pool cleanup will leak. They're still around because I
12681 haven't yet come up with a more elegant way of handling
12682 timeouts when talking to something that isn't the client. The
12683 default_handler and the dir_handler now use soft timeouts, largely
12684 so I can test the feature. [Robert Thau]
12686 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
12687 the case of log handlers dying prematurely is probably handled VERY
12688 gracelessly at this point, and if the logger stops reading input,
12689 the server will hang. (It is known to correctly restart the
12690 logging process on server restart; this is (should be!) going through
12691 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
12692 script). [Robert Thau]
12694 *) asis files supported (new module). [Robert Thau]
12696 *) IdentityCheck code is compiled in, but has not been tested. (I
12697 don't know anyone who runs identd). [Robert Thau]
12699 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
12700 came in with the request, for NCSA bug-compatibility. [Robert Thau]
12702 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
12704 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
12705 as timeouts are not in scope. [Robert Thau]
12707 *) quoted-string args in config files now handled correctly (doesn't drop
12708 the last character). [Robert Thau; reported by Randy Terbush]
12710 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
12711 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
12713 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
12714 default default type); the former default default behavior when all
12715 type-checkers defaulted had been a core dump. [Paul Sutton]
12717 *) Copy filenames out of the struct dirent when indexing
12718 directories. (On Linux, readdir() returns a pointer to the same
12719 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
12721 Changes with Shambhala 0.5.3 [not released]
12723 *) Default response handler notes "file not found" in the error log,
12724 if the file was not found. [Cliff Skolnick].
12726 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
12727 code no longer sets up bogus PATH_INFO which fakes out the directory
12728 handler). [Cliff Skolnick]
12730 Changes with Shambhala 0.5.2 06 Jul 1995
12732 *) Changes to http_main.c --- root server no longer plays silly
12733 games with SIGCHLD, and so now detects and replaces dying
12734 children. Child processes just die on SIGTERM, without taking
12735 the whole process group with them. Potential problem --- if any
12736 child process refuses to die, we hang in restart.
12737 MaxRequestsPerChild may still not work, but it certainly works
12738 better than it did before this! [Robert Thau]
12740 *) mod_dir.c bug fixes: ReadmeName and HeaderName
12741 work (or work better, at least); over-long description lines
12742 properly terminated. [Mark Cox]
12744 *) http_request.c now calls unescape_url() more places where it
12745 should [Paul Sutton].
12747 *) More directory handling bugs (reported by Cox)
12748 Parent Directory link is now set correctly. [Robert Thau]
12750 Changes with Shambhala 0.5.1 04 Jul 1995
12752 *) Generalized cleanup interface in alloc.c --- any function can be
12753 registered with alloc.c as a cleanup for a resource pool;
12754 tracking of files and file descriptors has been reimplemented in
12755 terms of this interface, so I can give it some sort of a test.
12758 *) More changes in alloc.c --- new cleanup_for_exec() function,
12759 which tracks down and closes all file descriptors which have been
12760 registered with the alloc.c machinery before the server exec()s a
12761 child process for CGI or <!--#exec-->. CGI children now get
12762 started with exactly three file descriptors open. Hopefully,
12763 this cures the problem Rob H. was having with overly persistent
12764 CGI connections. [Robert Thau]
12766 *) Mutual exclusion around the accept() in child_main() --- this is
12767 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
12768 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
12769 This uses fcntl(F_SETLK,...) on the error log descriptor because
12770 flock() on that descriptor won't work on systems which have BSD
12771 flock() semantics, including (I think) Linux 1.3 and Solaris.
12773 This does work on SunOS (when the server is idle, only one
12774 process in the pool is waiting on accept()); it *ought* to work
12775 on the other systems. [Robert Thau]
12777 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
12779 *) sizeof(*sa_client) bugfix from [Rob Hartill]
12781 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
12783 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
12784 be unnecessary if I go to the revised timeout-handling scheme).
12787 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
12788 string) even if none came in with the request. [Robert Thau]
12790 *) CHANGES file added to distribution ;-).
12792 Changes with Shambhala 0.4.5
12794 *) mod_dld --- early dynamic loading support [rst]
12795 *) Add wildcard content handlers for XBITHACK; default_hander now
12796 invoked with that mechanism (as a handler hanging off mod_core) [rst]
12797 *) XBITHACK supported as a wildcard content-handler, and
12798 configurable at run-time (not just at compile time, as in the
12799 "patchy server" releases) [rst]
12801 Changes with Shambhala 0.4.4 30 Jun 1995
12803 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
12804 *) Handle Addtype x/y .z [rst, reported by Cox]
12806 Changes with Shambhala 0.4.3
12808 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
12809 synonymous [rst, terbush]
12811 Changes with Shambhala 0.4.1 28 Jun 1995
12813 *) First-cut virtual host implementation; some refit in the config
12814 reading code, and log management, was necessary to support this [rst]
12815 *) Sub-pool machinery, originally added to avoid excessive storage
12816 allocation on listings of large directories (which turned out to
12817 be the problem that the 0.3 storage accounting was added to
12818 find). Subrequests and mod_dir changed to use subpools. [rst]
12819 *) More memory debugging --- free list consistency checks. [rst]
12820 *) Added err_headers to request_rec, with support elsewhere [rst]
12821 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
12823 Changes with Shambhala 0.3 19 Jun 1995
12825 *) Switch ONE_PROCESS to a runtime command-line option (-X)
12826 *) Don't compile in mod_ai_backcompat by default
12827 *) Switch name of server from Apache to Shambhala in Makefile
12828 *) Add some accounting routines to track memory usage in the pools,
12831 Changes with Shambhala 0.2
12833 *) Set DOCUMENT_ROOT CGI variable
12834 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
12835 *) Add critical section protection to handling of cleanup structures
12837 *) Significant code reorg within the server core to group related
12838 functions together [rst]
12839 *) Correctly handle clients that hang up before sending any request
12841 *) Replace dying child processes. [rst]
12843 Changes with Shambhala 0.1 12 Jun 1995
12845 Major rewrite of the pre-existing "patchy server" codebase, by
12846 Robert Thau (rst). Significant portions of the server code, such
12847 as configuration-file handling and HTTP authentication support,
12848 were ripped out and rewritten from scratch. Code that was not
12849 completely rewritten was significantly altered.
12851 Major changes with this release include:
12853 *) Introduction of the module API; in request handling, the central
12854 machinery just dispatches to various modules, which actually do
12855 most of the work. Configuration handling is similar --- modules
12856 declare their own commands, and the central machinery just
12857 dispatches to them.
12859 API features from shambhala/0.1 were substantially unchanged in
12860 Apache 1.0 and 1.1. (1.0 API features not yet present in this
12861 release, such as wildcard handlers and subpools, were added in
12862 subsequent Shambhala releases, and were also generally rst's
12865 *) This release included the following modules:
12867 mod_access (access control --- allow and deny directives),
12868 mod_alias (Alias and Redirect commands),
12869 mod_auth (straight HTTP authentication, based on flat-files)
12870 mod_auth_dbm (same, with dbm files)
12871 mod_cgi (CGI scripts and, in this release, ScriptAlias)
12872 mod_common_log (CLF access logs; later renamed mod_log_common)
12873 mod_dir (directory indexing)
12874 mod_include (server-side includes)
12875 mod_mime (AddType directives)
12876 mod_negotiation (content negotiation)
12877 mod_userdir (support for users' public_html directories)
12879 It also included a mod_ai_backcompat, which was a private hack
12880 for back-compatibility with rst's own AI-lab servers.
12882 All of these modules were substantially complete, and functional
12883 or nearly so (a few, which implemented features not in use at
12884 Thau's site, required patches of a few lines).
12886 *) sub-request machinery, to allow modules to determine how other
12887 modules would assign MIME types to a given file, or optionally
12888 serve its content (this is heavily used by mod_dir, mod_include
12889 and mod_negotiation).
12891 *) Resource pool system for keeping track of memory allocated and
12892 files opened in service of a particular request. Much of the
12893 code in the modules (when they weren't rewrites) was adjusted to
12894 replace a pervasive convention of using fixed-size buffers on
12895 the stack with an equally pervasive convention of using memory
12896 allocated with palloc().
12898 *) Reorganization of data structures associated with a given
12899 request to eliminate use of global variables and the troublesome
12900 unmunge_name function (used in NCSA and early Apache releases to
12901 attempt to determine the URI which mapped to a given filename
12902 --- a difficult proposition, given that it is easy to produce
12903 setups in which multiple URIs map to the same file).
12905 *) Source files renamed and rearranged
12907 *) Very simple pre-forking behavior --- parent process forked off a
12908 fixed number of children, and then just waited for SIGHUP.
12910 *) Other more minor changes too numerous to list.
12912 This release included modified versions of a lot of code from the
12913 Apache 0.6.4 public release, plus an early pre-forking patch
12914 codeveloped by Robert Thau and Rob Hartill.
12916 Changes with Apache 0.7.3 20 Jun 1995
12918 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
12919 were incorporated by Rob Hartill on the main branch while Robert Thau
12920 worked on the Shambhala rewrite above. Most were merged into the
