1 Changes with Apache 2.1.0-dev
3 [Remove entries to the current 2.0 section below, when backported]
5 *) Unix: Handle permissions settings for flock-based mutexes in
6 unixd_set_global|proc_mutex_perms(). Allow the functions to be
7 called for any type of mutex. PR 20312 [Jeff Trawick]
9 *) mod_rewrite: Perform child initialization on the rewrite log lock.
10 This fixes a log corruption issue when flock-based serialization
11 is used (e.g., FreeBSD). [Jeff Trawick]
13 *) Don't respect the Server header field as set by modules and CGIs.
14 As with 1.3, for proxy requests any such field is from the origin
15 server; otherwise it will have our server info as controlled by
16 the ServerTokens directive. [Jeff Trawick]
18 *) Fix some broken log messages in WinNT MPM.
19 [Juan Rivera <Juan.Rivera@citrix.com>]
21 *) Add support for "streamy" PROPFIND responses.
22 [Ben Collins-Sussman <sussman@collab.net>]
24 *) Add support for IMT minor-type wildcards (e.g., text/*) to
25 ExpiresByType. PR#7991 [Ken Coar]
27 *) Prevent the server from crashing when entering infinite loops. The
28 new LimitInternalRecursion directive configures limits of subsequent
29 internal redirects and nested subrequests, after which the request
30 will be aborted. PR 19753 (and probably others).
31 [William Rowe, Jeff Trawick, André Malo]
33 *) mod_rewrite: Fix LA-U variable look ahead which didn't work correctly
34 in directory context. Related to PR 8493. [André Malo]
36 *) Ensure that ssl-std.conf is generated at configure time, and switch
37 to using the expanded config variables to work the same as
38 httpd-std.conf PR 19611
41 *) Fix a problem with namespace mappings being dropped in mod_dav_fs;
42 if any property values were set which defined namespaces these
43 came out mangled in the PROPFIND response. PR 11637.
44 [Amit Athavale <amit_athavale@persistent.co.in>]
46 *) prefork MPM: Use the right permissions for the directory created
47 for gprof support. [Jim Carlson <jcarlson@jnous.com>]
49 *) Fix the inability to log errors like exec failure in
50 mod_ext_filter/mod_cgi script children. This was broken after
51 such children stopped inheriting the error log handle.
54 *) Fix a compile failure with recent OpenSSL and picky compilers
55 (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
57 *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
58 the INCLUDE path to be defined properly.
59 PR 11310. [Geoff Thrope <geoff@geoffthorpe.net>]
61 *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
63 *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
64 autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc).
65 [Geoff Thorpe <geoff@geoffthorpe.net>]
67 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
68 [Ian Holsman, André Malo]
70 *) mod_negotiation: quality values are now parsed independent from
71 the current locale. level values are now really parsed as integers.
72 PR 17564. [André Malo]
74 *) Added the WindowsSocketsWorkaround directive for Windows NT/2000/XP
75 to work around problems with certain VPN and Firewall products that
76 have buggy AcceptEx implementations.
77 [Allan Edwards w/ suggestions from Bill Stoddard & Bill Rowe]
79 *) Extend mod_negotiation to evaluate the environment variables
80 no-gzip and gzip-only-text/html the same way as mod_deflate does.
83 *) mod_rewrite: Fix some problems reporting errors with mapping
84 programs (RewriteMap prg:/something). [Jeff Trawick]
86 *) Return 413 if chunk-ext-header is too long rather than reading from
87 the truncated line. PR 15857. [Justin Erenkrantz]
89 *) Allow restart of httpd to occur even with syntax errors in the config
90 file. PR 16813. [Justin Erenkrantz]
92 *) Use APR_LAYOUT instead of APACHE_LAYOUT in configure. PR 15679.
95 *) Remove files on 'make distclean' that should be. PR 15592.
98 *) Allow apachectl to perform status with links and elinks as well.
101 *) Extend the SetEnvIf directive to capture subexpressions of the
102 matched value. [André Malo]
104 *) mod_log_config change optional hook to return previous handler
107 *) Forward port of mod_actions' ability to handle arbitrary methods
108 with the Script directive. [André Malo]
110 *) Let suexec send a message to stderr, if it failed or its policy
111 was violated. This message appears in the error log and allows
112 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
114 *) Modify buildconf to copy all required files into httpd's tree.
115 [Thom May <thom@planetarytramp.net>]
117 *) Allow mod_dav to do weak entity comparison functions.
120 *) Move RFC 1413 ident requests from core to new module mod_ident.
123 *) Add mod_authz_owner - a forward port of "Require file-owner"
124 and "Require file-group", which was already present in version
127 *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
130 *) Replace some of the mutex locking in the worker MPM with
131 atomic operations for higher concurrency. [Brian Pane]
133 *) Allow 'make depend' to work with non-GCC compilers.
136 *) If an httpd.conf has commented out AddModule directives,
137 apxs -i -a will add an un-commented AddModule directive for
138 the new module, which breaks the config.
139 PR: 11212 [Joe Orton]
141 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
143 *) Move the check of the Expect request header field after the hook
144 for ap_post_read_request, since that is the only opportunity for
145 modules to handle Expect extensions. [Justin Erenkrantz]
147 *) Rewrite of aaa modules to an authn/authz model.
148 [Dirk-Willem van Gulik, Justin Erenkrantz]
151 [Apache 2.1.0-dev includes those bug fixes and changes with the
152 Apache 2.0.xx tree as documented, and except as noted, below.]
154 Changes with Apache 2.0.47
156 *) mod_negotiation: Introduce "prefer-language" environment variable,
157 which allows to influence the negotiation process on request basis
158 to prefer a certain language. [André Malo]
160 *) Make mod_expires' ExpiresByType work properly, including for
161 dynamically-generated documents. [Ken Coar, Bill Stoddard]
163 Changes with Apache 2.0.46
165 *) SECURITY [CAN-2003-0245]: Fixed a bug causing apr_pvsprintf() to crash
166 by sending an overly long string. This can be triggered remotely
167 through mod_dav, mod_ssl, and other mechanisms. Reported by David
168 Endler <DEndler@iDefense.com>.
169 [Joe Orton <jorton@redhat.com>]
171 *) SECURITY [CAN-2003-0189]: Fixed a denial-of-service vulnerability
172 affecting basic authentication on Unix platforms related to
173 thread-safety in apr_password_validate(). The problem was reported
174 by John Hughes <john.hughes@entegrity.com>.
176 *) Fix for mod_dav. Call the 'can_be_activity' callback, if provided,
177 when a MKACTIVITY request comes in.
178 [Ben Collins-Sussman <sussman@collab.net>]
180 *) Perform run-time query in apxs for apr and apr-util's includes.
183 *) run libtool from the apr install directory (in case that is different
184 from the apache install directory) [Jeff Trawick]
186 *) configure.in: Play nice with libtool-1.5. [Wilfredo Sanchez]
188 *) If mod_mime_magic does not know the content-type, do not attempt to
189 guess. PR 16908. [Andrew Gapon <agapon@telcordia.com>]
191 *) ssl session caching(shmht) : Fix a SEGV problem with SHMHT session
193 [Andreas Leimbacher <andreasl67@yahoo.de>, Madhusudan Mathihalli]
195 *) Add a delete flag to htpasswd.
198 *) Fix mod_rewrite's handling of absolute URIs. The escaping routines
199 now work scheme dependent and the query string will only be
200 appended if supported by the particular scheme. [André Malo]
202 *) Add another check for already compressed content in mod_deflate.
203 PR 19913. [Tsuyoshi SASAMOTO <nazonazo@super.win.ne.jp>]
205 *) Fixes for VPATH builds; copying special.mk and any future .mk files
206 from the source tree as well as the build tree (now creates a usable
207 configuration for apxs), and eliminated redundant -I'nclude paths.
210 *) Code fixes, constness corrections and ssl_toolkit_compat.h updates
211 for SSLC and OpenSSL toolkit compatibility. Still work remains to
212 be done to cripple features based on the limitations of RSA's binary
213 distribution of their SSL-C toolkit.
214 [William Rowe, Madhusudan Mathihalli, Jeff Trawick]
216 *) Linux 2.4+: If Apache is started as root and you code
217 CoreDumpDirectory, coredumps are enabled via the prctl() syscall.
220 *) ap_get_mime_headers_core: allocate space for the trailing null
221 when folding is in effect.
222 PR 18170 [Peter Mayne <PeterMayne@SPAM_SUX.ap.spherion.com>]
224 *) Fix --enable-mods-shared=most and other variants. [Aaron Bannert]
226 *) mod_log_config: Add the ability to log the id of the thread
227 processing the request via new %P formats. [Jeff Trawick]
229 *) Use appropriate language codes for Czech (cs) and Traditional Chinese
230 (zh-tw) in default config files. PR 9427. [André Malo]
232 *) mod_auth_ldap: Use generic whitespace character class when parsing
233 "require" directives, instead of literal spaces only. PR 17135.
236 *) Hook mod_rewrite's type checker before mod_mime's one. That way the
237 RewriteRule [T=...] Flag should work as expected now. PR 19626.
240 *) htpasswd: Check the processed file on validity. If a line is not empty
241 and not a comment, it must contain at least one colon. Otherwise exit
242 with error code 7. [Kris Verbeeck <Kris.Verbeeck@ubizen.com>, Thom May]
244 *) Fix a problem that caused httpd to be linked with incorrect flags
245 on some platforms when mod_so was enabled by default, breaking
246 DSOs on AIX. PR 19012 [Jeff Trawick]
248 *) By default, use the same CC and CPP with which APR was built.
249 The user can override with CC and CPP environment variables.
252 *) Fix ap_construct_url() so that it surrounds IPv6 literal address
253 strings with []. This fixes certain types of redirection.
254 PR 19207. [Jeff Trawick]
256 *) forward port of buffer overflow fixes for htdigest. [Thom May]
258 *) Added AllowEncodedSlashes directive to permit control of whether
259 the server will accept encoded slashes ('%2f') in the URI path.
260 Default condition is off (the historical behaviour). This permits
261 environments in which the path-info needs to contain encoded
262 slashes. PR 543, 2389, 3581, 3589, 5687, 7066, 7865, 14639. [Ken Coar]
264 *) When using Redirect in directory context, append requested query
265 string if there's no one supplied by configuration. PR 10961.
268 *) Unescape the supplied wildcard pattern in mod_autoindex. Otherwise
269 the pattern will not always match as desired. PR 12596.
272 *) mod_autoindex now emits and accepts modern query string parameter
273 delimiters (;). Thus column headers no longer contain unescaped
274 ampersands. PR 10880 [André Malo]
276 *) Enable ap_sock_disable_nagle for Windows. This along with the
277 addition of APR_TCP_NODELAY_INHERITED to apr.hw will cause Nagle
278 to be disabled for Windows. [Allan Edwards]
280 *) Correct a mis-correlation between mpm_common.c and mpm_common.h;
281 This patch reverts us to pre-2.0.46 behavior, using the
282 ap_sock_disable_nagle noop macro, because ap_sock_disable_nagle
283 was never compiled on Win32. [Allan Edwards, William Rowe]
285 *) Fix a build problem with passing unsupported --enable-layout
286 args to apr and apr-util. This broke binbuild.sh as well as
287 user-specified layout parameters. PR 18649 [Justin Erenkrantz,
290 *) If a Date response header was already set in the headers array,
291 this value was ignored in favour of the current time. This meant
292 that Date headers on proxied requests where rewritten when they
293 should not have been. PR: 14376 [Graham Leggett]
295 *) Add code to buildconf that produces an httpd.spec file from
296 httpd.spec.in, using build/get-version.sh from APR.
299 *) Fixed a segfault when multiple ProxyBlock directives were used.
300 PR: 19023 [Sami Tikka <sami.tikka@f-secure.com>]
302 *) SECURITY [CAN-2003-0134] OS2: Fix a Denial of Service vulnerability
303 identified and reported by Robert Howard <rihoward@rawbw.com> that
304 where device names faulted the running OS2 worker process.
305 The fix is actually in APR 0.9.4. [Brian Havard]
307 *) Forward port: Escape special characters (especially control
308 characters) in mod_log_config to make a clear distinction between
309 client-supplied strings (with special characters) and server-side
310 strings. This was already introduced in version 1.3.25.
313 *) mod_deflate: Check also err_headers_out for an already set
314 Content-Encoding: gzip header. This prevents gzip compressed content
315 from a CGI script from being compressed once more. PR 17797.
318 Changes with Apache 2.0.45
320 *) Fix possible segfaults under obscure error conditions within the
321 cgid daemon. [Jeff Trawick, William Rowe]
323 *) SECURITY [CAN-2003-0132]: Close a Denial of Service vulnerability
324 identified by David Endler <DEndler@iDefense.com> on all platforms.
325 An unlimited stream of newlines were acceptable between requests
326 where each <lf> would allocate an 80 byte buffer, leading very
327 quickly to memory exahustion. [Brian Pane]
329 *) Added an rpm build script.
330 [Graham Leggett, Joe Orton <jorton@redhat.com>]
332 *) Simpler, faster code path for request header scanning [Brian Pane]
334 *) SECURITY: Eliminated leaks of several file descriptors to child
335 processes, such as CGI scripts. This fix depends on the APR library
336 release 0.9.2 or later (0.9.3 was distributed with the httpd
337 source tarball for Apache 2.0.45.) PR 17206
338 [Christian Kratzer <ck@cksoft.de>, Bjoern A. Zeeb <bz@zabbadoz.net>]
340 *) Fix path handling of mod_rewrite, especially on non-unix systems.
341 There was some confusion between local paths and URL paths.
342 PR 12902. [André Malo]
344 *) Prevent endless loops of internal redirects in mod_rewrite by
345 aborting after exceeding a limit of internal redirects. The
346 limit defaults to 10 and can be changed using the RewriteOptions
347 directive. PR 17462. [André Malo]
349 *) Win32: Avoid busy wait (consuming all the CPU idle cycles) when
350 all worker threads are busy.
351 [Igor Nazarenko <igor_nazarenko@hotmail.com>]
353 *) Keep the subrequest filter in place when a subrequest is
354 redirected. PR 15423. [Jeff Trawick]
356 *) you can now specify the compression level for mod_deflate.
357 [Ian Holsman, Stephen Pierzchala <stephen@pierzchala.com>,
358 Michael Schroepl <Michael.Schroepl@telekurs.de>]
360 *) mod_deflate: Extend the DeflateFilterNote directive to
361 allow accurate logging of the filter's in- and outstream.
364 *) Allow SSLMutex to select/use the full range of APR locking
365 mechanisms available to it. Also, fix the bug that SSLMutex uses
366 APR_LOCK_DEFAULT no matter what. PR 8122 [Jim Jagielski,
367 martin.t.kutschker@blackbox.net (Martin Kutschker)]
369 *) Restore the ability of htdigest.exe to create files that contain
370 more than one user. PR 12910. [André Malo]
372 *) Improve binary compatibility of the core between debug (aka
373 maintainer-mode) and a non-debug compile.
376 *) mod_usertrack: don't set the cookie in subrequests. This works
377 around the problem that cookies were set twice during fast internal
378 redirects. PR 13211. [André Malo]
380 *) mod_autoindex no longer forgets output format and enabled version
381 sort in linked column headers. [André Malo]
383 *) Use .sv instead of .se as extension for Swedish documents in the
384 default configuration. PR 12877. [André Malo]
386 *) Updated mod_ldap and mod_auth_ldap to support the Novell LDAP SDK SSL
387 and standardized the LDAP SSL support across the various LDAP SDKs.
388 Isolated the SSL functionality to mod_ldap rather than speading it
389 across mod_auth_ldap and mod_ldap. Also added LDAPTrustedCA
390 and LDAPTrustedCAType directives to mod_ldap to allow for a more
391 common method of specifying the SSL certificate.
392 [Dave Ward, Brad Nicholes]
394 *) Fixed mod_ssl's SSLCertificateChain initialization to no longer
395 skip the first cert of the chain by default. This misbehavior
396 was introduced in 2.0.34. PR 14560 [Madhusudan Mathihalli]
398 *) mod_cgi, mod_cgid, mod_ext_filter: Log errors when scripts cannot
399 be started on Unix because of such problems as bad permissions,
400 bad shebang line, etc. [Jeff Trawick]
402 *) Fix 64-bit problem in mod_ssl input logic.
403 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
405 *) Fix potential memory leaks in mod_deflate on malformed data. PR 16046.
408 *) Rewrite ap_xml_parse_input to use bucket brigades. PR 16134.
411 *) Fix segfault which occurred when a section in an included
412 configuration file was not closed. PR 17093. [André Malo]
414 *) Enhance the behavior of mod_isapi's WriteClient() callback to
415 provide better emulation for isapi modules that presume that the
416 first WriteClient() call may send status and headers. An example
417 of WriteClient() abuse is the foxisapi module, which relies on
418 that assumpion and now works. [William Rowe, Milan Kosina]
420 *) Check the return value of ap_run_pre_connection(). So if the
421 pre_connection phase fails (without setting c->aborted)
422 ap_run_process_connection is not executed. [Stas Bekman]
424 *) Fixed a problem with mod_ldap which caused it to fault when caching
425 was disabled. Needed to make sure that the code did not
426 attempt to use the cache if it didn't exist. Also fixed some memory
427 leaks which were due to not releasing LDAP resources on error
428 conditions. [Brad Nicholes]
430 *) Hook mod_proxy's fixup before mod_rewrite's fixup, so that by
431 mod_rewrite proxied URLs will not be escaped accidentally by
432 mod_proxy's fixup. PR 16368 [André Malo]
434 *) While processing filters on internal redirects, remember seen EOS
435 buckets also in the request structure of the redirect issuer(s). This
436 prevents filters (such as mod_deflate) from adding garbage to the
437 response. PR 14451. [André Malo]
439 *) suexec: Be more pedantic when cleaning environment. Clean it
440 immediately after startup. PR 2790, 10449.
441 [Jeff Stewart <jws@purdue.edu>, André Malo]
443 *) Fix apxs to insert LoadModule directives only outside of sections.
444 PR 8712, 9012. [André Malo]
446 *) Fix suexec compile error under SUNOS4, where strerror() doesn't
447 exist. PR 5913, 9977.
448 [Jonathan W Miner <Jonathan.W.Miner@lmco.com>]
450 *) Fix If header parsing when a non-mod_dav lock token is passed to it.
451 PR 16452. [Justin Erenkrantz]
453 *) mod_auth_digest no longer tries to guess AuthDigestDomain, if it's
454 not specified. Now it assumes "/" as already documented. PR 16937.
457 *) Try to log an error if a piped log program fails. Try to
458 restart a piped log program in more failure situations. Fix an
459 existing problem with error handling in piped_log_spawn(). Use
460 new APR apr_proc_create() features to prevent Apache from starting
461 on Unix* in most cases where a piped log program can be started,
462 and add log messages for the other situations. *Other platforms
463 already failed Apache initialization if a piped log program
464 couldn't be started. PR 15761 [Jeff Trawick]
466 *) Fix mod_cern_meta to not create empty metafiles when the
467 metafile searched for does not exist. PR 12353
468 [Owen Rees <owen_rees@hp.com>]
470 *) Introduce debugging symbols for Win32 release builds, both .pdb
471 and .dbg files (older debuggers and Dr. Watson-type utilities
472 on WinNT or Win9x don't support the newer .pdb flavor.)
473 [Allen Edwards, William Rowe]
475 *) Fix bug where 'Satisfy Any' without an AuthType lost all MIME
476 information (and more). Related to PR 9076. [André Malo]
478 *) mod_file_cache: fix segfault serving mmaped cached files.
481 *) mod_file_cache: fixed a segfault when multiple MMapFile directives
482 were used. PR 16313. [Cliff Woolley]
484 *) Fix a nasty segfault in mmap_bucket_setaside() caused by passing
485 an incompatible pointer type to mmap_bucket_destroy(void*).
486 [Gerard Eviston <geviston@bigpond.net.au>]
488 *) Enable the -n name parameter on NetWare to allow the
489 administrator to rename the Apache console screen
492 *) Fixed piped access logs on Win32 by disabling OTHER_CHILD
493 support by default in APR. More development is required
494 to deploy OTHER_CHILD on Win32. [William Rowe]
496 *) Use saner default config values for suexec. PR 15713.
497 [Thom May <thom@planetarytramp.net>]
499 *) mod_rewrite: Allow "RewriteEngine Off" even if no "Options FollowSymlinks"
500 (or SymlinksIfOwnermatch) is set. PR 12395. [André Malo]
502 *) apxs: Include any special APR ld flags when linking the DSO.
503 This resolves problems on AIX when building a DSO with apxs+gcc.
506 *) Added character set support to mod_auth_LDAP to allow it to
507 convert extended characters used in the user ID to UTF-8
508 before authenticating against the LDAP directory. The new
509 directive AuthLDAPCharsetConfig is used to specify the config
510 file that contains the character set conversion table.
513 *) Don't remove the Content-Length from responses in mod_proxy
514 PR: 8677 [Brian Pane]
516 *) Ensure LDAP version is set to v3 on every bind. PR 14235.
517 [Sergey A. Lipnevich <sergeyli@pisem.net>]
519 *) Fix mod_ldap to open an existing shared memory file should one
520 already exist. PR 12757. [Scooter Morris <scooter@gene.com>,
523 *) Fix the ulimit command used by apachectl on Tru64. PR 13609.
524 [Joseph Senulis <Joseph.Senulis@dnr.state.wi.us>, Jeff Trawick]
526 *) Change the ulimit command used by apachectl on AIX so that it
527 works in all locales. [Jeff Trawick]
529 *) mod_ext_filter: Fix a problem building argument lists which
530 occasionally caused exec to fail. PR 15491. [Jeff Trawick]
532 Changes with Apache 2.0.44
534 *) mod_autoindex: Bring forward the IndexOptions IgnoreCase option
535 from Apache 1.3. PR 14276
536 [David Shane Holden <dpejesh@yahoo.com>, William Rowe]
538 *) mod_mime: Workaround to prevent a segfault if r->filename=NULL
541 *) Reorder the definitions for mod_ldap and mod_auth_ldap within
542 config.m4 to make sure the parent mod_ldap is defined first.
543 This ensures that mod_ldap comes before mod_auth_ldap in the
544 httpd.conf file, which is necessary for mod_auth_ldap to load.
545 PR 14256 [Graham Leggett]
547 *) Fix the building of cgi command lines when the query string
548 contains '='. PR 13914 [Ville Skyttä <ville.skytta@iki.fi>,
551 *) Rename CacheMaxStreamingBuffer to MCacheMaxStreamingBuffer. Move
552 implementation of MCacheMaxStreamingBuffer from mod_cache to
553 mod_mem_cache. MCacheMaxStreamingBuffer now defaults to the
554 lesser of 100,000 bytes or MCacheMaxCacheObjectSize. This should
555 eliminate the need for explicitly coding MCacheMaxStreamingBuffer
556 in most configurations. [Bill Stoddard]
558 *) mod_cache: Fix PR 15113, a core dump in cache_in_filter when
559 a redirect occurs. The code was passing a format string and
560 integer to apr_pstrcat. Changed to apr_psprintf.
563 *) Replace APU_HAS_LDAPSSL_CLIENT_INIT with APU_HAS_LDAP_NETSCAPE_SSL
564 as set by apr-util in util_ldap.c. This should allow mod_ldap
565 to work with the Netscape/Mozilla LDAP library. [Øyvin Sømme
566 <somme@oslo.westerngeco.slb.com>, Graham Leggett]
568 *) Fix critical bug in new --enable-v4-mapped configure option
569 implementation which broke IPv4 listening sockets on some
570 systems. [hiroyuki hanai <hanai@imgsrc.co.jp>]
572 *) mod_setenvif: Fix BrowserMatchNoCase support for non-regex
573 patterns [André Malo <nd@perlig.de>]
575 *) Add version string to provider API. [Justin Erenkrantz]
577 *) build: './configure && make' now works without an in-tree
578 apr and apr-util. [Wilfredo Sanchez]
580 *) mod_negotiation: Set the appropriate mime response headers
581 (Content-Type, charset, Content-Language and Content-Encoding)
582 for negotated type-map "Body:" responses (such as the error
583 pages.) [André Malo <nd@perlig.de>]
585 *) mod_log_config: Allow '%%' escaping in CustomLog format
586 strings to insert a literal, single '%'.
587 [André Malo <nd@perlig.de>]
589 *) mod_autoindex: AddDescription directives for directories
590 now work as in Apache 1.3, where no trailing '/' is
591 specified on the directory name. Previously, the trailing
592 '/' *had* to be specified, which was incompatible with
593 Apache 1.3. PR 7990 [Jeff Trawick]
595 *) Fix for PR 14556. The expiry calculations in mod_cache were
596 trying to perform "now + ((date - lastmod) * factor)" where
597 date == lastmod resulting in "now + 0". The code now follows
598 the else path (using the default expiration) if date is
599 equal to lastmod. [rx@armstrike.com (Sergey), Paul J. Reder]
601 *) Use AP_DECLARE in the debug versions of ap_strXXX in case the
602 default calling convention is not the same as the one used by
603 AP_DECLARE. [Juan Rivera <Juan.Rivera@citrix.com>]
605 *) mod_cache: Don't cache response header fields designated
606 as hop-by-hop headers in HTTP/1.1 (RFC 2616 Section 13.5.1).
607 [Estrade Matthieu <estrade-m@ifrance.com>, Brian Pane]

610 PR 14550 [Piotr Czejkowski <apache@czarny.eu.org>, Jeff
613 *) Move mod_ext_filter out of experimental and into filters.
616 *) Fixed a memory leak in mod_deflate with dynamic content.
617 PR 14321 [Ken Franken <kfranken@decisionmark.com>]
619 *) Add --[enable|disable]-v4-mapped configure option to control
620 whether or not Apache expects to handle IPv4 connections
621 on IPv6 listening sockets. Either setting will work on
622 systems with the IPV6_V6ONLY socket option. --enable-v4-mapped
623 must be used on systems that always allow IPv4 connections on
624 IPv6 listening sockets. PR 14037 (Bugzilla), PR 7492 (Gnats)
627 *) This fixes a problem where the underlying cache code
628 indicated that there was one more element on the cache
629 than there actually was. This happened since element 0
630 exists but is not used. This code allocates the correct
631 number of useable elements and reports the number of
632 actually used elements. The previous code only allowed
633 MCacheMaxObjectCount-1 objects to be stored in the
634 cache. [Paul J. Reder]
636 *) mod_setenvif: Add SERVER_ADDR special keyword to allow
637 envariable setting according to the server IP address
638 which received the request. [Ken Coar]
640 *) mod_cgid: Terminate CGI scripts when the client connection
641 drops. PR 8388 [Jeff Trawick]

647 *) Always emit Vary header if mod_deflate is involved in the
648 request. [Andre Malo <nd@perlig.de>]
650 *) mod_isapi: Stop unsetting the 'empty' query string result with
651 a NULL argument in ecb->lpszQueryString, eliminating segfaults
652 for some ISAPI modules. PR 14399
653 [Detlev Vendt <detlev.vendt@brillit.de>]
655 *) mod_isapi: Fix an issue where the HSE_REQ_DONE_WITH_SESSION
656 notification is received before the HttpExtensionProc() returns
657 HSE_STATUS_PENDING. This only affected isapi .dll's configured
658 with the ISAPIFakeAsync on directive. PR 11918
659 [John DeSetto <jdesetto@radiantsystems.com>, William Rowe]
661 *) mod_isapi: Fix the issue where all results from mod_isapi would
662 run through the core die handler resulting in invalid responses
663 or access log entries. PR 10216 [William Rowe]
665 *) Improves the user friendliness of the CacheRoot processing
666 over my last pass. This version avoids the pool allocations
667 but doesn't avoid all of the runtime checks. It no longer
668 terminates during post-config processing. An error is logged
669 once per worker, indicating that the CacheRoot needs to be set.
672 *) Fix a bug where we keep files open until the end of a
673 keepalive connection, which can result in:
674 (24)Too many open files: file permissions deny server access
675 especially on threaded servers. [Greg Ames, Jeff Trawick]
677 *) Fix a bug in which mod_proxy sent an invalid Content-Length
678 when a proxied URL was invoked as a server-side include within
679 a page generated in response to a form POST. [Brian Pane]
681 *) Added code to process min and max file size directives and to
682 init the expirychk flag in mod_disk_cache. Added a clarifying
683 comment to cache_util. [Paul J. Reder]
685 *) The value emitted by ServerSignature now mimics the Server HTTP
686 header as controlled by ServerTokens. [Francis Daly <deva@daoine.org>]
688 *) Gracefully handly retry situations in the SSL input filter,
689 by following the SSL libraries' retry semantics.
692 *) Terminate CGI scripts when the client connection drops. This
693 fix only applies to some normal paths in mod_cgi. mod_cgid
694 is still busted. PR 8388 [Jeff Trawick]
696 *) Fix a bug where 416 "Range not satisfiable" was being
697 returned for content that should have been redirected.

711 *) Emit a message to the error log when we return 404 because
712 the URI contained '%2f'. (This was previously nastily silent
713 and difficult to debug.) [Ken Coar]
715 *) Fix streaming output from an nph- CGI script. CGI:IRC now
716 works. PR 8482 [Jeff Trawick]
718 *) More accurate logging of bytes sent in mod_logio when
719 the client terminates the connection before the response
720 is completely sent [Bojan Smojver <bojan@rexursive.com>]
722 *) Fix some problems in the perchild MPM.
723 [Jonas Eriksson <jonas@webkonsulterna.com>]
725 *) Change the CacheRoot processing to check for a required
726 value at config time. This saves a lot of wasted processing
727 if the mod_disk_cache module is loaded but no CacheRoot
728 was provided. This fix also adds code to log an error
729 and avoid useless pallocs and procesing when the computed
730 cache file name cannot be opened. This also updates the
731 docs accordingly. [Paul J. Reder]
733 *) Introduce the EnableSendfile directive, allowing users of NFS
734 shares to disable sendfile mechanics when they either fail
735 outright or provide intermitantly corrupted data. PR
738 *) Resolve the error "An operation was attempted on something
739 that is not a socket. : winnt_accept: AcceptEx failed.

741 anti-virus software on Windows. PR 8325 [William Rowe]
743 *) Add the ProxyBadHeader directive, which gives the admin some
744 control on how mod_proxy should handle bogus HTTP headers from
745 proxied servers. This allows 2.0 to "emulate" 1.3's behavior if
746 desired. [Jim Jagielski]

771 *) SECURITY [CAN-2002-0840]: HTML-escape the address produced by
772 ap_server_signature() against this cross-site scripting
773 vulnerability exposed by the directive 'UseCanonicalName Off'.
774 Also HTML-escape the SERVER_NAME environment variable for CGI
775 and SSI requests. It's safe to escape as only the '<', '>',
776 and '&' characters are affected, which won't appear in a valid
777 hostname. Reported by Matthew Murphy <mattmurphy@kc.rr.com>.
780 *) Fix a core dump in mod_cache when it attemtped to store uncopyable
781 buckets. This happened, for instance, when a file to be cached
782 contained SSI tags to execute a CGI script (passed as a pipe
783 bucket). [Paul J. Reder]
785 *) Ensure that output already available is flushed to the network
786 when the content-length filter realizes that no new output will
787 be available for a while. This helps some streaming CGIs as

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

912 No sense wasting cycles on unused code. Besides, the only truly
913 bug free code is deleted code. :) [Paul J. Reder]
915 *) BufferLogs are now run-time enabled, and the log_config now has 2 new

955 *) mod_disk_cache works much better. This module should still
956 be considered experimental. [Eric Prud'hommeaux]
958 *) Performance improvement for keepalive requests: when setting
959 aside a small file for potential concatenation with the next
960 response on the connection, set aside the file descriptor rather
961 than copying the file into the heap. [Brian Pane]
963 *) Modified version check on openssl so that it finds the executable
964 first and then performs a check of the version, only warning the
965 user if they chose, or we selected, an old version of OpenSSL.
966 This change also allows the code to work for non-openssl libraries
967 selected via the --with-ssl=dir option, which can override the
968 automated library check in any case. [Roy Fielding]
970 Changes with Apache 2.0.40
972 *) SECURITY [CAN-2002-0661] (cve.mitre.org):
973 Close a very significant security hole that
974 applies only to the Win32, OS2 and Netware platforms. Unix was not
975 affected, Cygwin may be affected. Certain URIs will bypass security
976 and allow users to invoke or access any file depending on the system
977 configuration. Without upgrading, a single .conf change will close
978 the vulnerability. Add the following directive in the global server
979 httpd.conf context before any other Alias or Redirect directives;

1033 *) Replace usage of atol() to parse strings when we might want a
1034 larger-than-long value with apr_atoll(), which returns long long.
1035 This allows HTTPD to deal with larger files correctly.
1036 [Shantonu Sen <ssen@apple.com>]
1038 *) mod_ext_filter: Ignore any content-type parameters when checking if
1039 the response should be filtered. Previously, "intype=text/html"
1040 wouldn't match something like "text/html;charset=8859_1".
1043 *) mod_ext_filter: Set up environment variables for external programs.
1044 [Craig Sebenik <craig@netapp.com>]
1046 *) Modified the HTTP_IN filter to immediately append the EOS (end of
1047 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
1048 the caller to determine that no content remains without prefetching
1049 additional POST body. [William Rowe]

1076 *) Performance improvements for the code that reads request
1077 headers (ap_rgetline_core() and related functions) [Brian Pane]
1079 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
1080 to configure the maximum amount of memory the allocators will
1081 hold on to for reuse. Anything over the MaxMemFree threshold
1082 will be free()d. This directive is useful when uncommon large
1083 peaks occur in memory usage. It should _not_ be used to mask
1084 defective modules' memory use. [Sander Striker]
1086 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
1087 scripts would not result in a truncated response.
1088 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
1090 *) Add a filter_init parameter to the filter registration functions
1091 so that a filter can execute arbitrary code before the handlers
1092 are invoked. This resolves a problem where mod_include requests
1093 would incorrectly return a 304. [Justin Erenkrantz]
1095 *) Fix a long-standing bug in 2.0, CGI scripts were being called
1096 with relative paths instead of absolute paths. Apache 1.3 used
1097 absolute paths for everything except for SuExec, this brings back
1098 that standard. [Ryan Bloom]
1100 *) Fix infinite loop due to two HTTP_IN filters being present for
1101 internally redirected requests. PR 10146. [Justin Erenkrantz]

1117 *) Normalize the hostname value in the request_rec to all-lowercase
1118 [Perry Harrington <pedward@webcom.com>]
1120 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
1121 extended characters (non US-ASCII) in non-utf8 format. This brings
1122 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
1123 to the cgi application itself. [William Rowe]
1125 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
1126 modules to bring them up to the current apr/apr-util APIs.
1129 *) Fix segfault in mod_mem_cache most frequently observed when
1130 serving the same file to multiple clients on an MP machine.

1147 helper functions and relying on current filter assumptions.
1150 Changes with Apache 2.0.39

1153 [Guenter Knauf <eflash@gmx.net>, Cliff Woolley]
1155 Changes with Apache 2.0.38
1157 *) Rewrite htpasswd to use APR. The removes the annoying warning about
1158 tmpnam being unsafe. [Ryan Bloom]
1160 *) We must set the MIME-type for .shtml files to text/html if we want them
1161 to be parsed for SSI tags. Add the config for that to the default
1162 config file so that it is easier to enable .shtml parsing.

1165 *) Fixed a problem with 'make install' on ReliantUnix.
1166 [Jean-frederic Clere <jfrederic.clere@fujitsu-siemens.com>]
1168 *) Make the default_handler catch all requests that aren't served by
1169 another handler. This also gets us to return a 404 if a directory
1170 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1171 loaded. [Justin Erenkrantz]
1173 *) Fixed the handling of nested if-statements in shtml files.
1174 PR 9866 [Brian Pane]
1176 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1177 into a directory different from the one that was configured. This
1178 also mirrors the root= feature from 1.3. We cannot use prefix=,
1179 because both APR and APR-util resolve their installation paths at
1180 configuration time. This means that there is no variable prefix
1181 to replace. [Andreas Hasenack <andreas@netbank.com.br>]
1183 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1184 These levels of AIX don't have a thundering herd problem with
1185 accept(). [Jeff Trawick]
1187 *) prefork MPM: Ignore mutex errors during graceful restart. For
1188 certain types of mutexes (particularly SysV semaphores), we
1189 should expect to occasionally fail to obtain or release the
1190 mutex during restart processing. [Jeff Trawick]
1192 *) Fix install-bindist.sh so that it finds any perl instead of just
1193 early perl 5.x versions. This is consistent with a build/install
1194 from source, and it allows the perl scripts installed by a bindist
1195 to work on systems with perl 5.6. [Jeff Trawick]
1197 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
1198 Tru64 (and probably some other platforms). [Jeff Trawick]
1200 *) Allow CGI scripts to return their Content-Length. This also fixes a

1216 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
1217 session cache when there is no cert chain in the cache. prior to
1218 the fix this situation would result in a FORBIDDEN response and
1219 error message "Cannot find peer certificate chain"

1267 *) Remove all special mod_ssl URIs. This also fixes the bug where
1268 redirecting (.*) will allow an SSL protected page to be viewed

1275 *) Allow instdso.sh to work with full paths to the shared module.
1278 *) NetWare: Enabled CGI functionality and added mod_cgi as a built

1281 *) Changed cgi and piped log behavior to accept 65536 characters

1321 stripping the content_type from cached responses.
1324 *) apachectl passes through any httpd options. Note: apachectl

1380 *) Remove SSLLog and SSLLogLevel directives in favor of having
1381 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
1383 *) OS/390: LIBPATH no longer has to be manually uncommented in

1498 *) Many improvements to the threadpool MPM. [Aaron Bannert]
1500 *) Fix subreqs that are promoted via fast_redirect from having invalid

1556 *) SECURITY: Added the APLOG_TOCLIENT flag to ap_log_rerror() to
1557 explicitly tell the server that warning messages should be sent
1558 to the client in addition to being recorded in the error log.
1559 Prior to this change, ap_log_rerror() always sent warning
1560 messages to the client. In one case, a faulty CGI script caused
1561 the server to send a warning message to the client that contained
1562 the full path to the CGI script. This could be considered a
1563 minor security exposure. [Bill Stoddard]
1565 *) mod_autoindex output when SuppressRules was specified would

1580 clean up some stray files and symlinks that libtool leaves around
1581 on some platforms. This gets subversion building properly since
1582 it needed a re-link to be performed by libtool at install time,

1705 to take over scoreboard slots from a previous generation, we'll be
1706 accepting connections we can't process yet. [Jeff Trawick]
1708 *) Allow worker MPM to build on systems without pthread_kill().
1709 [Pier Fumagalli, Jeff Trawick]
1711 *) Prevent ap_add_output_filters_by_type from being called in
1712 ap_set_content_type if the content-type hasn't changed.
1715 *) Performance: implemented the bucket allocator made possible by the
1716 API change in 2.0.34. [Cliff Woolley]
1718 *) Don't allow initialization to succeed if we can't get a socket
1719 corresponding to one of the Listen statements. [Jeff Trawick]
1721 Changes with Apache 2.0.34
1723 *) Allow all Perchild directives to accept either numerical UID/GID
1724 or logical user/group names. [Scott Lamb <slamb@slamb.org>]
1726 *) Make Perchild compile cleanly and serve pages again. [Ryan Bloom]
1728 *) implement ssl proxy to support ProxyPass / https:// and the
1729 SSLProxy* directives [Doug MacEachern]
1731 *) Update mod_cgid to not do single-byte socket reads for CGI headers
1734 *) Made AB's use of the Host: header rfc2616 compliant
1735 by Taisuke Yamada <tai@iij.ad.jp> [Dirk-Willem van Gulik].
1737 *) The old, legacy (and unused) code in which the scoreboard was totally
1738 and completely contained in a file (SCOREBOARD_FILE) has been
1739 removed. This does not affect scoreboards which are *mapped* to
1740 files using named-shared-memory. [Jim Jagielski]
1742 *) Change bucket brigades API to allow a "bucket allocator" to be
1743 passed in at certain points. This allows us to implement freelists
1744 so that we can stop using malloc/free so frequently.
1745 [Cliff Woolley, Brian Pane]
1747 *) Add support for macro expansion within the variable names in
1748 <!--#echo--> and <!--#set--> directives [Brian Pane]
1750 *) Fix some mod_include segfaults [Cliff Woolley, Brian Pane, Brad Nicholes]
1752 *) Update the "RedHat" Layout to match Red Hat Linux version 7. PR BZ-7422
1755 *) add compat layer to support RSA SSLC 1.x and 2.x in mod_ssl
1756 [Jon Travis, John Barbee, William Rowe, Ryan Bloom, Doug MacEachern]
1758 *) Add a new parameter to the quick_handler hook to instruct
1759 quick handlers to optionally do a lookup rather than actually
1760 serve content. This is the first of several changes required fix
1761 several problems with how quick handlers work with subrequests.
1764 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]
1766 *) [APR-related] The ordering of the default accept mutex method has
1767 been changed to better match what's done in Apache 1.3. The ordering
1768 is now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
1771 *) Ensure that the build/ directory is created when using VPATH.
1774 *) Add some popular types to the mime magic file. PR 7730.
1775 [Linus Walleij <triad@df.lth.se>, Justin Erenkrantz]
1777 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
1779 *) When a proxied site was being served, Apache was replacing
1780 the original site Server header with it's own, which is not
1781 allowed by RFC2616. Fixed. [Graham Leggett]
1783 *) Fix a mod_cgid problem that left daemon processes stranded
1784 in some server restart scenarios. [Jeff Trawick]
1786 *) Added exp_foo and rel_foo variables to config_vars.mk for
1787 all Apache and Autoconf path variables (like --sysconfdir,
1788 --sbindir, etc). exp_foo is the "expanded" version, which means
1789 that all internal variable references have been interpolated.
1790 rel_foo is the same as $exp_foo, only relative to $prefix if they
1791 share a common path. [Aaron Bannert]
1793 *) Fix some restart/terminate problems in the worker MPM. Don't
1794 drop connections during graceful restart. [Jeff Trawick]
1796 *) Change the header merging behaviour in proxy, as some headers
1797 (like Set-Cookie) cannot be unmerged due to stray commas in
1798 dates. [Graham Leggett]
1800 *) Be more vocal about what AcceptMutex values we allow, to make
1801 us closer to how 1.3 does it. [Jim Jagielski]
1803 *) Get nph- CGI scripts working again. PRs 8902, 8907, 9983
1806 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
1808 *) Add accessor function to set r->content_type. From now on,
1809 ap_rset_content_type() should be used to set r->content_type.
1810 This change is required to properly implement the
1811 AddOutputFilterByType configuration directive.
1812 [Bill Stoddard, Sander Striker, Ryan Bloom]
1814 *) Add new M_FOO symbols for the WebDAV/DeltaV methods specified by
1815 RFC 3253. Improved the method name/number mapping functions.
1818 *) remove sock_enable_linger from connection.c [Ian Holsman]
1820 *) Fix for virtual host processing where the requested hostname
1821 has a '.' at the end (PR 9187) [Ryan Cruse <ryan@estara.com>]
1823 *) mod_dav's APIs for REPORT response handling was changed so that
1824 providers can generate the content directly into the output filter
1825 stack, rather than buffering the response into memory. [Greg Stein]
1827 *) Fix a hang condition with graceful restart and prefork MPM
1828 in the situation where MaxClients is very high but
1829 much fewer servers are actually started at the time of the
1830 restart. [Jeff Trawick]
1832 *) Small performance fixes for mod_include [Brian Pane]
1834 *) Performance improvement for the error logger [Brian Pane]
1836 *) Change configure so that Solaris 8 and above have
1837 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
1838 according to sun people solaris 8+ doesn't have a thundering
1839 herd problem [Ian Holsman]
1841 *) Allow URIs specifying CGI scripts to include '/' at the end
1842 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
1843 which ignore '/' at the end of the names of non-directories).
1844 PR 10138 [Jeff Trawick]
1846 *) implement SSLSessionCache shmht and shmcb based on apr_rmm and
1847 apr_shm. [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1849 *) Fix apxs -g handling. Move config_vars.mk from the top build
1850 directory to the build directory. PR 10163 [Jeff Trawick]
1852 *) Fix some mod_include problems which broke evaluation of some
1853 expressions. PR 10108 [Jeff Trawick]
1855 *) Fix the calculation of request time in mod_status. [Stas Bekman]
1857 *) Fix the calculation of thread_num in the worker score structure.
1860 *) Use apr_atomic operations in managing the mod_mem_cache
1861 cache_objects for SMP scalability. (see USE_ATOMICS
1862 preprocessor directive in mod_file_cache)
1865 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
1866 preprocessor directive in mod_file_cache)
1869 *) Implement prototype mod_disk_cache for use with mod_cache.
1872 *) Add a missing manualdir entry in the Debian config.layout.
1873 [Thom May <thom@planetarytramp.net>]
1875 *) Stop installing libtool for APR and tell APR where it should place
1876 its copy of libtool (via our installbuildpath layout variable).
1879 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
1880 when reading from a remote HTTP server in proxy. [Graham Leggett]
1882 *) Modify receive/send loop in proxy_http and proxy_ftp so that
1883 should it be necessary, the remote server socket is closed before
1884 transmitting the last buffer (set by ProxyIOBufferSize) to the
1885 client. This prevents the backend server from being forced to hang
1886 around while the last few bytes are transmitted to a slow client.
1887 Fix the case where no error checking was performed on the final
1888 brigade in the loop. [Graham Leggett]
1890 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
1891 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
1892 hours. [Graham Leggett, Bill Stoddard]
1894 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
1895 for a undefined variable. [Ian Holsman]
1897 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
1898 when we can't get a socket in the specified address family. We may
1899 have gotten back an IPv6 address first and yet our system is not
1900 configured to allow IPv6 sockets. [Jeff Trawick]
1902 *) Be more careful about recursively removing CVS directories. Make
1903 sure that we aren't cd'ing to their home directory first. PR: 9993
1904 [Aaron Bannert, James LewisMoss <dres@lewismoss.net>]
1906 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
1907 [Dirk-Jan Faber <dirk-jan@selwerd.nl>, Aaron Bannert,
1908 Thom May <thom@planetarytramp.net>]
1910 *) Rename the filter ordering priorities. The recent filtering fixes
1911 have showcased problems with their usage. Therefore, we need to
1912 rename them to increase the clarity. (CONTENT->RESOURCE,
1913 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
1915 Changes with Apache 2.0.33
1917 *) Fix a problem in the new --enable-layout functionality where
1918 it wouldn't allow overrides from variables like --prefix,
1919 --bindir, etc. [Thom May <thom@planetarytramp.net>]
1921 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
1922 no longer hangs around waiting for the socket to close before
1923 returning exhaustive data. [Aaron Bannert]
1925 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
1926 [Thom May <thom@planetarytramp.net>]
1928 *) Change mod_ssl to always do a full startup/teardown on restarts.
1929 this allows mod_ssl to be added to a server that is already
1930 running and makes it possible to add/change certs/keys after the
1931 server has been started. [Doug MacEachern]
1933 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
1934 This pipe must be a bidirectional 'console' style relay, which
1935 mod_ssl prints all prompts to the pipe's stdin, and reads the
1936 passphrases from the pipe's stdout. [William Rowe]
1938 *) Fix bug where --sysconfdir and --localstatedir were being
1939 ignored. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
1942 *) Fix --enable-layout to work again. Caution: When specifying
1943 --enable-layout, common arguments like --prefix, --exec-prefix,
1944 etc. will be ignored and the settings from the layout will be
1945 used instead. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
1948 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
1949 regex pattern matching for the determination of which requests
1950 to use the remote proxy for. [Jim Jagielski]
1952 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
1954 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
1955 cruft in piped logs and rewritemap child processes.
1958 *) All instances of apr_lock_t have been removed and converted
1959 to one of the following new lock APIs: apr_thread_mutex.h,
1960 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
1961 use the apr_lock.h API, as the old API will soon be deprecated.
1964 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
1965 [Ralf S. Engelschall, Cliff Woolley]
1967 *) mod-include: make it handle flush'es and fix the 'false-alarm'
1968 [Justin Erenkrantz, Brian Pane, Ian Holsman]
1970 *) ap_get_*_filter_handle() functions to allow 3rd party modules
1971 to lookup filter handles so they can bypass the filter name
1972 lookup when adding filters to a request (via ap_add_*_filter_handle())
1973 [Ryan Morgan <rmorgan@covalent.net>]
1975 *) Fix for multiple file buckets on Win32, where the first file
1976 bucket would cause the immediate closure of the socket on any
1977 non-keepalive requests. [Ryan Morgan <rmorgan@covalent.net>]
1979 *) Correct Win32 failure of mmap of a segment beyond start of the
1980 file; fixes large SSL and similar transfers. [William Rowe]
1983 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
1984 multi-process mode to not "daemonize" while detaching from the
1985 controlling terminal. This is necessary for Apache to work with
1986 process-management tools like AIX's "System Resource Controller"
1987 as well as Dan Bernstein's "daemontools".
1988 [Jos Backus <josb@cncdsl.com>, Aaron Bannert]
1990 *) Convert mod_auth_digest to use the new apr_global_mutex_t
1991 type. [Aaron Bannert]
1993 *) fix bug in mod-include where it wouldn't send a unmatched
1994 part if it was at the end of a bucket [Ian Holsman]
1996 *) worker MPM: Improve logging of errors with the interface between
1997 the listener thread and worker threads. [Jeff Trawick]
1999 *) Some browsers ignore cookies that have been merged into a
2000 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
2001 are now unmerged in the http proxy before being sent to the
2002 client. [Graham Leggett]
2004 *) Fix a problem with proxy where each entry of a duplicated
2005 header such as Set-Cookie would overwrite and obliterate the
2006 previous value of the header, resulting in multiple header
2007 values (like cookies) going missing.
2008 [Graham Leggett, Joshua Slive]
2010 *) Add the server-limit and thread-limit values to the scoreboard
2011 for the sake of third-party applications.
2012 [Adam Sussman <myddryn@vishnu.vidya.com>]
2014 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
2016 *) OS/390: Get make install to properly copy DSO modules.
2019 *) Win32: Fix bug in mod_status with displaying "Restart Time"
2020 and "Server uptime".
2023 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
2025 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
2027 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
2028 [David MacKenzie <djm@pix.net>]
2030 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
2031 [David MacKenzie <djm@pix.net>]
2033 *) Fix segfault and display error when SSLMutex file can not be
2034 created. [Adam Sussman <myddryn@vishnu.vidya.com>]
2036 *) Add reference counting to mod_mem_cache cache objects to
2037 better manage removing objects from the cache.
2040 *) Change the verbage on the ScoreBoardFile in our default configs.
2041 Also change the default to be commented out (unspecified) so we
2042 get anonymous shared memory by default. [Aaron Bannert]
2044 *) Implement new ScoreBoardFile directive logic. This affects how
2045 we create the scoreboard's shared memory segment. If the directive
2046 is present, a name-based segment is created. If the directive is
2047 not present, first an anonymous segment is created, and if that
2048 fails, a name-based segment is created from a file of the name
2049 DEFAULT_SCOREBOARD. This gives third-party applications the
2050 ability to access our scoreboard. [Aaron Bannert]
2052 *) Allow mod_deflate to work with non-GET requests and properly send
2053 Content-Lengths. [Sander Striker <striker@apache.org>]
2055 *) Fix ap_directory_merge() to correctly merge configs when there is
2056 no <Directory /> block. [Justin Erenkrantz, William Rowe]
2058 *) Remove spurious debug messsages that are normal under HTTP
2059 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
2061 *) Fix a bug in mod_cgid that would prevent proper shutdown death
2062 of the cgid process. [Aaron Bannert]
2064 *) Add signal handling back in to the worker MPM for the one_process
2065 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
2067 *) Performance: Reuse per-connection transaction pools in the
2068 worker MPM, rather than destroying and recreating them. [Brian Pane]
2070 *) Remove all signals from the worker MPM's child process. Instead,
2071 the parent uses the Pipe of Death for all communication with the
2072 child processes. [Ryan Bloom]
2074 Changes with Apache 2.0.32
2076 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
2077 default if the directive is not specified. This mirrors older
2078 behavior without changes to the httpd.conf. [William Rowe]
2080 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
2081 the service, mpm and logging code, and bugs in apr_file_open_stderr
2082 and apr_file_dup2 functions. Win2K/XP services have no handles
2083 associated for stdin/out/err, which caused unpredictable behavior
2084 in the prior release. [William Rowe, Bill Stoddard]
2086 *) Win32: simplify the Application Event Log messages, since there isn't
2087 likely to be 'more information in the error log' before an error log
2088 has been opened. [William Rowe]
2090 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
2091 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
2093 *) Win32: apache -k shutdown now behaves like apache -k stop.
2096 *) Fix prefork to not kill the parent if a child hits a resource shortage
2097 on accept(). [Greg Ames]
2099 *) Fix seg faults that occur when what should be the httpd request line
2100 starts with \r\n followed by garbage. [Greg Ames]
2102 *) Allow statically linked support binaries with the new
2103 --enable-static-support flag, and enable this behavior in
2104 the binbuild script. Also add a new --enable-static-htdbm
2105 flag. [Aaron Bannert]
2107 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
2108 do only one stat() call when generating the directory listings.
2111 *) Fix resolve_symlink to save the original symlink name if known.
2114 *) Be a bit more sane with regard to CanonicalNames. If the user has
2115 specified they want to use the CanonicalName, but they have not
2116 configured a port with the ServerName, then use the same port that
2117 the original request used. [Ryan Bloom and Ken Coar]
2119 *) In core_input_filter, check for an empty brigade after
2120 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
2121 client says it will post some data but we get FIN before any
2122 data arrives. [Jeff Trawick]
2124 *) Not being able to bind to the socket is a fatal error. We should
2125 print an error to the console, and return a non-zero status code.
2126 With these changes, all of the Unix MPMs do that correctly.
2129 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
2130 through to CGI scripts. PR 9163
2131 [Brian Reid <breid@customlogic.com>,
2132 Zvi Har'El <rl@math.technion.ac.il>]
2134 *) binbuild.sh: Make sure that we use the expat from our source
2135 tree so that there aren't any surprises on the target machine.
2138 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2139 enough to keep up with new requests. Start using
2140 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2141 when we can't talk to the daemon. [Jeff Trawick]
2143 *) apxs: LTFLAGS envvar can override default libtool options. Try
2144 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2145 the covers. [Jeff Trawick]
2147 *) The Location: response header field, used for external
2148 redirect, *must* be an absoluteURI. The Redirect directive
2149 tested for that, but RedirectMatch didn't -- it would allow
2150 almost anything through. Now it will try to turn an abs_path
2151 into an absoluteURI, but it will correctly varf like Redirect
2152 if the final redirection target isn't an absoluteURI. [Ken Coar]
2154 Changes with Apache 2.0.31
2156 *) Create the scoreboard (in the parent) in a global pool context,
2157 so it survives graceful restarts. This fixes a SEGV during
2158 graceful restarts. [Aaron Bannert]
2160 *) Add a timeout option to the proxy code 'ProxyTimeout'
2163 *) FTP directory listings are now always retrieved in ASCII mode.
2164 The FTP proxy properly escapes URI's and HTML in the generated
2165 listing, and escapes the path components when talking to the FTP
2166 server. It is now possible to browse the root directory by using
2167 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2168 Also, the last path component may contain wildcard characters
2169 '*' and '?', and if they do, a directory listing is created instead
2170 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2173 *) Added single-listener unserialized accept support to the
2174 worker MPM [Brian Pane]
2176 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2177 the incoming host header through to the proxied server
2178 [Geoff <g.russell@ieee.org>]
2180 *) New Directive Option for ProxyPass. It now can block a location
2181 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
2183 *) Don't let the default handler try to serve a raw directory. At
2184 best you get gibberish. Much worse things can happen depending
2185 on the OS. [Jeff Trawick]
2187 *) Change the pre_config hook to return a value. Modules can now emit
2188 an error message and then cause the server to quit gracefully during
2189 startup. This required a bump to the MMN. [Aaron Bannert]
2191 *) Fix some unix socket descriptor leaks in the handler side of
2192 mod_cgid (the part that runs in the server process). Whack a
2193 silly "close(-1)" in the handler too. [Jeff Trawick]
2195 *) Change the pre_mpm hook to return a value, so that scoreboard
2196 init errors percolate up to code that knows how to exit
2197 cleanly. This required a bump to the MMN. [Jeff Trawick]
2199 *) Add the socket back to the conn_rec and remove the create_connection
2200 hook. The create_connection hook had a design flaw that did not
2201 allow creating connections based on vhost info. [Bill Stoddard]
2203 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2204 Resolves the common case of using negotation to resolve the request
2205 /script/foo for /script.cgi/foo. [William Rowe]
2207 *) Added new functions ap_add_(input|output)_filter_handle to
2208 allow modules to bypass the usual filter name lookup when
2209 adding hard-coded filters to a request [Brian Pane]
2211 *) caching should now work on subrequests (still very experimental)
2214 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2216 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2219 *) Refactor ap_rgetline so that it does not use an internal brigade.
2220 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2222 *) Remove mod_auth_db. [Justin Erenkrantz]
2224 *) Do not install unnecessary pcre headers like config.h and internal.h.
2225 [Joe Orton <joe@manyfish.co.uk>]
2227 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
2228 (as it does for a normal request). quick_handled sub-requests now work
2229 in mod-include [Ian Holsman]
2231 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
2232 'CONTENT' one, as it needs to run AFTER all content headers
2234 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
2237 *) Split out blocking from the mode in the input filters.
2240 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
2242 *) Cause Win32 to capture all child-worker process errors in
2243 Apache to the main server error log, until the child can
2244 open its own error logs. [William Rowe]
2246 *) HPUX 11.*: Do not kill the child process when accept()
2247 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
2248 by [madhusudan_mathihalli@hp.com])
2251 *) Fix a problem in the parsing of the <Proxy foo> directive.
2254 *) rewrite of mod_ssl input filter for better performance and less
2255 memory usage [Doug MacEachern]
2257 *) allow quick_handler to be run on subrequests. [Ian Holsman]
2259 *) mod_dav now asks its provider to place content directly into the
2260 filter stack when handling a GET request. The mod_dav/provider
2261 API has changed, so providers need to be updated. [Greg Stein]
2263 *) Clear the output socket descriptor in unixd_accept() to make sure
2264 we don't supply a bogus socket to the caller if the accept fails.
2265 This caused problems with the worker MPM, which tried to process
2266 the returned socket if it was non-NULL. [Brian Pane]
2268 *) Move a check for an empty brigade to the start of core input filter
2269 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
2271 *) Add FileETag directive to allow configurable control of what
2272 data are used to form ETag values for file-based URIs. MMN
2273 bumped to 20020111 because of fields added to the end of
2274 the core_dir_config structure. [Ken Coar]
2276 *) Fix a segfault in mod_rewrite's logging code caused by passing the
2277 wrong config to ap_get_remote_host(). [Jeff Trawick]
2279 *) Allow mod_cgid to work from a binary distribution install by
2280 using 755 for the permissions on the log directory instead of
2283 *) Fixed a segfault that happened during graceful shutdown (or when
2284 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
2286 *) Split all Win32 modules [excluding the core components mod_core,
2287 mod_so, mod_win32 and the winnt mpm] into individual loadable
2288 modules, so the administrator may individually disable the former
2289 compiled-in modules by simply commenting out their LoadModule
2290 directives. [William Rowe]
2292 *) Saved Win32 module authors and porters many future headaches, by
2293 duplicating the appropriate .h files such as os.h into the include
2294 directory, including in the build tree. [William Rowe]
2296 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
2297 Use SSL functions/macros instead of directly dereferencing SSL
2298 structures wherever possible.
2299 Add type-casts for the cases where functions return a generic pointer.
2300 Add $SSL/include to configure search path.
2301 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2303 *) Moved several pointers out of the shared Scoreboard so it is
2304 more portable, and will present the vhost name across server
2305 generation restarts. [William Rowe]
2307 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
2310 Changes with Apache 2.0.30
2312 *) Fix the main bug for FreeBSD and threaded MPM's. There are
2313 still issues (see STATUS) but at least the server will now
2314 run without crashing the machine.
2315 [David Reid, Aaron Bannert, Justin Erenkrantz]
2317 *) Fix a typo in mod_deflate's m4 config section.
2318 [albert chin (china@thewrittenword.com)]
2320 *) Fix a couple of mod_proxy problems forwarding HTTP connections
2321 and handling CONNECT:
2322 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
2323 (2) Proxy failed to connect when the first IP address returned by
2324 the resolver was unreachable but a secondary IP address was.
2327 *) Fix the module identifer as shown in the docs for various core
2328 modules (e.g., the identifer for mod_log_config was previously
2329 listed as config_log_module). PR #9338
2330 [James Watson <ap2bug@sowega.org>]
2332 *) Fix LimitRequestBody directive by placing it in the HTTP
2333 filter. [Justin Erenkrantz]
2335 *) Fix mod_proxy seg fault when the proxied server returns
2336 an HTTP/0.9 response or a bogus status line.
2339 *) Prevent mod_proxy from truncating one character off the
2340 end of the status line returned from the proxied server.
2341 [Adam Sussman, Bill Stoddard]
2343 *) Eliminate loop in ap_proxy_string_read().
2344 [Adam Sussman, Bill Stoddard]
2346 *) Provide $0..$9 results from mod_include regex parsing.
2349 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
2351 *) Introduced the ForceLanguagePriority directive, to prevent
2352 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
2353 when using Multiviews. [William Rowe]
2355 *) Fix a problem which prevented mod_cgid and suexec from working
2356 together reliably [Greg Ames]
2358 *) Remove the call to exit() from within mod_auth_digest's post_config
2359 phase. [Aaron Bannert]
2361 *) Fix a problem in mod_auth_digest that could potentially cause
2362 problems with initialized static data on a system that uses DSOs.
2365 *) Fix a segfault in the worker MPM that could happen during
2366 child process exits. [Brian Pane, Aaron Bannert]
2368 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
2370 *) Fix matching of vhosts by ip address so we find IPv4
2371 vhost address when target address is v4-mapped form of
2372 that address. [Jeff Trawick]
2374 *) More performance tweaks to the BNDM string-search algorithm
2375 used to find "<!--#" tokens in mod_include [Brian Pane]
2377 *) Miscellaneous small performance fixes: optimized away various
2378 string copy operations and removed large temp buffers from
2379 the stack [Brian Pane]
2381 *) Fixed startup segfault that occurred when a VirtualHost
2382 directive had a port but no address [Brian Pane]
2384 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
2386 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
2387 if oslevel < WINNT. This should fix several problems reported
2388 Against 2.0.28 on Windows 98 [Bill Stoddard]
2390 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
2391 to fail. [Bill Stoddard]
2393 *) Change core code to allow an MPM to set hard thread/server
2394 limits at startup. prefork, worker, and perchild MPMs now have
2395 directives to set these limits. [Jeff Trawick]
2397 *) Win32: The async AcceptEx() event should be autoreset upon
2398 successful completion of a wait (WaitForSingleObject). This
2399 eliminates a number of spurious
2400 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
2403 *) Move any load library path environment variables out of
2404 apachectl and into a separate environment variable file which
2405 can be more easily tailored by the admin. The environment
2406 variable file as built by Apache may have additional system-
2407 specific settings. For example, on OS/390 we tailor the heap
2408 settings to allow lots of threads. [Jeff Trawick]
2410 *) Use the new APR pool code to reduce pool-related lock
2411 contention in the worker MPM. [Sander Striker]
2413 *) The POD no longer assumes the child is listening on 127.0.0.1
2414 and now pulls the first hostname in the list of listeners to
2415 perform the dummy connect on. This fixes a bug when the user
2416 had configured the Listen directive for an IP other than
2417 127.0.0.1. This would result in undead children and error
2418 messages such as "Connection refused: connect to listener".
2421 *) The worker MPM now respects the LockFile setting, needed to
2422 avoid locking problems with NFS. [Jeff Trawick]
2424 *) Fix segfault when worker MPM receives SIGHUP.
2425 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
2427 *) Fix bug that could potentially prevent the perchild MPM from
2428 working with more than one vhost/uid. [Aaron Bannert]
2430 *) Change make install and apxs -i processing of DSO modules to
2431 perform special handling on platforms where libtool doesn't install
2432 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
2433 which prevented standard LoadModule statements from working.
2436 *) Whenever mod_so is enabled (not just when there are DSOs for
2437 our modules), do whatever special magic is required for compiling/
2438 loading third-party modules. This allows third-party DSOs to
2439 be used on an AIX build when there were no built-in modules
2440 built as DSOs. (This should help on OS/390 and BeOS as well.)
2443 *) Allow apxs to be used to build DSOs on AIX without requiring the
2444 user to hard-code the list of import files. (This should help
2445 on OS/390 and BeOS as well.) [Jeff Trawick]
2447 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
2448 PR 8563, 8919 [William Rowe]
2450 *) Get binary builds working when libapr and libaprutil are built
2453 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
2454 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
2455 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
2457 *) Fix the handling of SSI directives in which the ">" of the
2458 terminating "-->" is the last byte in a file [Brian Pane]
2460 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
2461 message that we had back in apache-1.3 and still have scattered
2462 throughout our docs. [Aaron Bannert]
2464 *) Prevent the Win32 port from continuing after encountering an
2465 error in the command line args to apache. [William Rowe]
2467 *) On a error in the proxy, make it write a line to the error log
2470 *) Various mod_ssl performance improvements [Doug MacEachern]
2472 Changes with Apache 2.0.29
2474 *) Add buffering in core_output_filter to ensure that long
2475 lists of small buckets don't cause small packet writes.
2476 [Brian Pane, Ryan Bloom]
2478 *) Fix the installation target to make sure that the manual is
2479 installed in the correct location.
2480 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
2481 Gomez Henri <hgomez@slib.fr>]
2483 *) Fix the cmd command for mod_include. When we are processing
2484 a cmd command, we do not want to use the r->filename to set
2485 the command name. The command comes from the SSI tag. To do this,
2486 I added a variable to the function that builds the command line
2487 in mod_cgi. This allows the include_cmd function to specify
2488 the command line itself. [Ryan Bloom]
2490 *) Change open_logs hook to return a value, allowing you
2491 to flag a error while opening logs
2492 [Ian Holsman, Doug MacEachern]
2494 *) Change post_config hook to return a value, allowing you
2495 to flag a error post config
2496 [Ian Holsman, Jeff Trawick]
2498 *) Allow SUEXEC_BIN (the path to the suexec binary that is
2499 hard-coded into the server) to be specified to the configure
2500 script by the --with-suexec-bin parameter. [Aaron Bannert]
2502 *) Fix segv in worker MPM following accept on pipe-of-death
2505 *) Add mod_deflate to experimental.
2506 [Ian Holsman, Justin Erenkrantz]
2508 *) Bail out at configure time if an invalid MPM was specified.
2509 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2511 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
2512 configured [John Sterling <sterling@covalent.net>]

2518 *) Optimization for the BNDM string-search function in
2519 mod_include. [Brian Pane]
2521 *) Fixed the behavior of the XBitHack directive.
2522 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
2524 *) The threaded MPM for Unix has been removed. Use the worker
2525 MPM instead. [various]
2527 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
2528 in logging the error from a failed DNS lookup. [Jeff Trawick]
2530 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
2533 *) Get mod_cgid killed when a MPM exits due to a fatal error.
2536 *) Fix a file descriptor leak in mod_include. When we include a
2537 file, we use a sub-request, but we didn't destroy the sub-request
2538 immediately, instead we waited until the original request was
2539 done. This patch closes the sub-request as soon as the data is
2540 done being generated. [Brian Pane <bpane@pacbell.net>]
2542 *) Allow modules that add sockets to the ap_listeners list to
2543 define the function that should be used to accept on that
2544 socket. Each MPM can define their own function to use for
2545 the accept function with the MPM_ACCEPT_FUNC macro. This
2546 also abstracts out all of the Unix accept error handling
2547 logic, which has become out of synch across Unix MPMs.
2550 *) Fix a bug which would cause the response headers to be omitted
2551 when sending a negotiated ErrorDocument because the required
2552 filters were attached to the wrong request_rec.
2553 [John Sterling <sterling@covalent.net>]
2555 *) Remove commas from the end of the macros that define
2556 directives that are used by MPMs. Prior to this patch,
2557 you would use these macros without commas, which was unlike
2558 the macros for any other directives. Now, the caller provides
2559 the comma rather than the macro providing it. This makes
2560 the macros look more like the rest of the directives.
2561 [Ryan Bloom and Cliff Woolley]
2563 *) Add 'redirect-carefully' environment option to disable sending
2564 redirects under special circumstances. This is helpful for
2565 Microsoft's WebFolders when accessing a directory resource via
2566 DAV methods. [Justin Erenkrantz]
2568 *) Begin to abstract out the underlying transport layer.
2569 The first step is to remove the socket from the conn_rec,
2570 the server now lives in a context that is passed to the
2571 core's input and output filters. This forces us to be very
2572 careful when adding calls that use the socket directly,
2573 because the socket isn't available in most locations.
2576 *) Really reset the MaxClients value in worker and threaded
2577 when the configured value is not a multiple of the number
2578 of threads per child. We said we did previously but we
2579 forgot to. [Jeff Trawick]
2581 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
2583 *) If shared modules are requested and mod_so is not available,
2584 produce a fatal config-time error. [Justin Erenkrantz]
2586 *) Improve http2env's performance by cutting the work it has to
2587 do. [Brian Pane <bpane@pacbell.net>]
2589 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
2590 [Brian Pane <bpane@pacbell.net>]
2592 Changes with Apache 2.0.28
2594 *) Fix infinite loop in mod_cgid.c.
2595 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
2597 *) When no port is given in a "ServerName host" directive, the
2598 server_rec->port is now set to zero, not 80. That allows for
2599 run-time deduction of the correct server port (depending on
2600 SSL/plain, and depending also on the current setting of
2601 UseCanonicalName). This change makes redirections
2602 work, even with https:// connections. As in Apache-1.3, the
2603 connection's actual port number is never used, only the ServerName
2604 setting or the client's Host: setting. Documentation updated
2605 to reflect the change. [Martin Kraemer]
2607 *) Add a '%{note-name}e' argument to mod-headers, which works in
2608 the same way as mod_log_confg. [Ian Holsman]
2610 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
2611 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
2612 MPMs. [Cliff Woolley]
2614 *) Introduce htdbm, a user management utility for db/dbm authorization
2615 databases. [Mladen Turk <mturk@mappingsoft.com>]
2617 *) Optimize usage of strlen and strcat in ap_directory_walk.
2618 [Brian Pane <bpane@pacbell.net>]
2620 Changes with Apache 2.0.27
2622 *) Introduce an Apache mod_ssl initial configuration template
2623 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
2625 *) Fixed a memory leak in the getline parsing code that could
2626 be triggered by arbitrarily large header lines. Requests
2627 from the core input filter for single lines are now limited
2628 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
2630 *) Fix a truncation bug in how we print the port on the Via: header.
2631 The routine that prints the Via: header now takes a length for
2632 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
2634 *) Some syntax errors in mod_mime_magic's magic file can result
2635 in a 500 error, which previously was unlogged. Now we log the
2636 error. [Jeff Trawick]
2638 *) Add the support/checkgid helper app, which checks the run-time
2639 validity of group identifiers usable in the Group directive.
2642 *) Various --enable-so options have been fixed: --enable-so is
2643 treated as "static"; explicit --enable-so=shared issues an error;
2644 and explicit --enable-so fails with error on systems without
2645 APR_HAS_DSO. [Aaron Bannert]
2647 *) Fix a segfault in the core input filter when the client socket
2648 gets disconnected unexpectedly. [Cliff Woolley]
2650 *) Fix the reporting for child processes that die. This removes
2651 all of the non-portable W* macros from Apache.
2652 [Jeff Trawick and Ryan Bloom]
2654 *) Win32: Track and display "Parent Server Generation:" in
2655 mod_status output. The generation will be bumped at
2656 server graceful restart, when the child process exits
2657 by hitting MaxRequestsPerChild or if the child
2658 process exits abnormally. [Bill Stoddard]
2660 *) Win32: Fix problem where MaxRequestsPerChild directive was
2661 not being picked up in favor of the default. Enable
2662 the parent to start up a new child process immediately upon
2663 the old child starting shutdown.
2666 *) Fix some bungling of the remote port in rfc1413.c so that
2667 IdentityCheck retrieves the proper user id instead of failing
2668 and thus always returning "nobody."
2669 [Dick Streefland <Dick.Streefland@xs4all.nl>]
2671 *) Introduced thread saftey for mod_rewrite's internal cache.
2672 [Brian Pane <bpane@pacbell.net>]
2674 *) Simplified mod_env's directives to behave as most directives are
2675 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
2676 directive following that UnsetEnv within the same container.
2677 Also provides a runtime startup warning if a PassEnv configured
2678 environment value is undefined. [William Rowe]
2680 *) The worker MPM is now completely ported to APR's new lock API. It
2681 uses native APR types for thread mutexes, cross-process mutexes,
2682 and condition variables. [Aaron Bannert]
2684 *) Sync up documentation to remove all references to the now deprecated
2685 Port directive. [Justin Erenkrantz]
2687 *) Moved all ldap modules from the core to httpd-ldap sub-project
2690 *) Exit when we can't listen on any of the configured ports. This
2691 is the same behavior as 1.3, and it avoids having the MPMs to
2692 deal with bogus ap_listen_rec structures. [Jeff Trawick]
2694 *) Cleanup the proxy code that creates a request to the origin
2695 server. This change adds an optional hook, which allows modules
2696 to gain control while the request is created if the proxy module
2697 is loaded. The purpose of this hook is to allow modules to add
2698 input and/or output filters to the request to the origin. While
2699 I was at it, I made the core use this hook, so that proxy request
2700 creation uses some of the code from the core. This can still be
2701 greatly improved, but this is a good start. [Ryan Bloom]
2703 Changes with Apache 2.0.26
2705 *) Port the MaxClients changes from the worker MPM to the threaded
2708 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
2709 with the new input filtering system. [Justin Erenkrantz]
2711 *) Introduce the MultiviewsMatch directive, to allow the operator
2712 to be flexible in recognizing Handlers and Filters filename
2713 extensions as part of the Multiviews matching logic, strict with
2714 MultiviewsMatch NegotiatedOnly to accept only filename extentions
2715 that designate negotiated parameters, (content type, charset, etc.)
2716 or MultiviewsAll for the 1.3 behavior of matching any files, even
2717 if they have unregistered extensions. [William Rowe]
2719 *) Fixed the configure script to add a LoadModule directive to
2720 the default httpd.conf for any module that was compiled
2721 as a DSO. [Aaron Bannert <aaron@clove.org>]
2723 *) rewrite mod_ssl input filtering to work with the new input filtering
2724 system. [Justin Erenkrantz]
2726 *) prefork: Don't segfault when we are able to listen on some but
2727 not all of the configured ports. [Jeff Trawick]
2729 *) Build mod_so even if no core modules are built shared.
2730 [Aaron Bannert <aaron@clove.org>]
2732 *) Introduce ap_directory_walk rewrite (with further optimizations
2733 required) to adapt to the ap_process_request_internal() changes.
2734 Optimized so subrequests and redirects now reuse previous section
2735 merges, until we mismatch with the original directory_walk, and
2736 precomputed r->finfo results will cause directory_walk to skip
2737 the most expensive phases of the function. [William Rowe]
2739 *) Allow ApacheMonitor to connect to and control Apache on other
2740 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
2742 *) Remove the Port directive. In it's place, the Listen directive
2743 is now a required directive, which tells Apache what port to
2744 listen on. The ServerName directive has also been extended
2745 to accept an optional port. If the port is specified to the
2746 ServerName, the server will report that port whenever it
2747 reports the port that it is listening on. This change was
2748 made to ease configuration errors that stem from having a Port
2749 directive, and a Listen directive. In that situation, the server
2750 would only listen to the port specified by the Listen command,
2751 which caused a lot of confusion to users. [Ryan Bloom]
2753 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
2754 build, as loadable modules. [William Rowe]
2756 *) Fix --enable-mods-shared processing. If most is specified,
2757 then all modules that can be compiled as shared modules are.
2758 [Aaron Bannert <aaron@clove.org>]
2760 *) Update the mime.types file to map video/vnd.mpegurl to mxu
2761 and add commonly used audio/x-mpegurl for m3u extensions.
2762 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
2764 *) Eliminate the depreciated r->content_language, in favor of the array
2765 r->content_languages introduced many years ago. Module authors must
2766 substantially overhaul their modules, so this needs to be upgraded
2767 if the module still relied on backwards-brokeness. [William Rowe]
2769 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
2772 *) Rewrite the input filtering mechanisms to consolidate and reorganize
2773 code. In short, core_input_filter does something now and
2774 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
2776 *) Update the Win32 build to re-absorb mod_proxy and family.
2779 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
2780 current SDK.) [William Rowe]
2782 *) Some style changes to the code that does ProxyErrorOverride. Fixed
2783 config merge behaviour. [Graham Leggett]
2785 *) Allow support programs to be compiled against a static version
2786 of libapr. This allows the smaller support programs to be
2787 relocated. [Aaron Bannert <aaron@clove.org>]
2789 *) Update the mime.types file to the registered media types as
2790 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
2792 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
2793 number of clients that can connect at the same time, instead of
2794 specifying the maximum number of child processes.
2795 [Aaron Bannert <aaron@clove.org>]
2797 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
2798 be consistent with 1.3. [Justin Erenkrantz]
2800 *) Cache apr_explode_localtime() value for 15 seconds.
2801 [Brian Pane <bpane@pacbell.net>]
2803 *) Fix mod_include to not return ETag or Last-Modified headers.
2804 [Ian Holsman <ianh@cnet.com>]
2806 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
2808 *) Eliminate the wasteful run-time conversion of method names from strings
2809 to numbers in places where the methods are known at compile time.
2810 [Brian Pane <bpane@pacbell.net>]
2812 *) Turn the worker MPM's queue into a LIFO. This may
2813 improve cache-hit performance under some conditions.
2814 [Aaron Bannert <aaron@clove.org>]
2816 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
2817 support it. [Justin Erenkrantz]
2819 *) Cleanup the worker MPM. We no longer re-use transaction
2820 pools. This incurs less overhead than shuffling the pools
2821 around so that they can be re-used. Remove one of the
2822 queue's condition variables. We just redefined the API to
2823 state that you can't try to add more stuff than you allocated
2824 segments for. [Aaron Bannert <aaron@clove.org>]
2826 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
2828 *) Fixed persistent connections when a request contains a body.
2831 *) mod_dav uses a new API to speak to the backend provider for dead
2832 property management. [Greg Stein]
2834 *) Remove the Win32 script-processing exception from mod_cgi, and
2835 roll build_command_line/build_argv_list into a unified, overrideable
2836 ap_cgi_build_command optional function. [William Rowe]
2838 *) Rewrite find_start_sequence to use a better search algorithm
2839 to find the start tag. [Justin Erenkrantz]
2841 *) Fix a seg fault in mod_include. When we are generating an
2842 internal redirect, we must set r->uri to "", not a bogus
2843 string, and not NULL. [Ryan Bloom]
2845 *) Optimized location_walk, so subrequests, redirects and second passes
2846 now reuse previous section merges on a <Location > by <Location >
2847 basis, until we mismatch with the original location_walk.
2850 *) Back out the 1.45 change to util_script.c. This change made
2851 us set the environment variable REQUEST_URI to the redirected
2852 URI, instead of the originally requested URI.
2853 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2855 *) Make mod_include do lazy evaluation of potentially expensive to
2856 compute variables. [Brian Pane <bpane@pacbell.net>]
2858 *) Fix logging of bytes sent for HEAD requests. %b and %B should
2859 log either - or 0, before this patch, they were both logging
2860 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2862 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
2863 than per character. [Brian Pane <bpane@pacbell.net>]
2865 *) Normalize the primary request, redirects and sub-requests to
2866 run the same ap_process_request_internal for consistency in
2867 robustness, behavior and security. [William Rowe]
2869 *) Fix a segfault with mod_include when r->path_info is not set
2870 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
2872 *) Add -X functionality back. This indicates to all MPMs and any other
2873 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
2875 *) Some initial support for the cygwin platform [prefork only].
2876 This is not to be confused with support for the WinNT/Win32
2877 platform, which is the recommended configuration for native
2878 Win32 users. The cygwin platform support is recommended for
2879 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
2881 *) Changed syntax of Set{Input|Output}Filter. The list of filters
2882 must be semicolon delimited (if more than one filter is given.)
2883 The Set{Input|Output}Filter directive now overrides a parent
2884 container's directive (e.g. SetInputFilter in <Directory /web/foo>
2885 will override any SetInputFilter directive in <Directory /web>.)
2886 This new syntax is more consistent with Add{Input|Output}Filter
2887 directives defined in mod_mime. Also cures a bug in prior releases
2888 where the Set{Input|Output}Filter directive would corrupt the
2889 global configuration if the multiple directives were nested.
2892 *) Cured what's ailed mime for quite some time. If an AddSomething
2893 was given in the configuration (Language, Charset, Handler or
2894 Encoding) Apache would set the content type as given by AddType,
2895 but refused to check the mime.types file if AddType wasn't given
2896 for that specific extension. Setting the AddHandler for .html
2897 without setting the AddType text/html html would cause Apache to
2898 use the default content type. [William Rowe]
2900 *) Added some bulletproofing to memory allocation in the LDAP cache
2901 code. [Graham Leggett]
2903 Changes with Apache 2.0.25
2905 *) Move the installed /manual directory out of the /htdocs/ tree, so
2906 that it can be kept more independently from the remaining document
2907 root. The "Alias /manual ..." already allowed for easy projection
2908 into existing private document trees. [Martin Kraemer]
2910 *) Add specified user attributes to the environment when using
2911 mod_auth_ldap. This allows you to use mod_include to embed specified
2912 user attributes in a page like so:
2913 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
2916 *) Fix a performance problem with the worker MPM. We now create
2917 transaction pools once, and re-use them for each connection.
2918 [Aaron Bannert <aaron@clove.org>]
2920 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
2921 of a 'handler' or 'filter', so that any filename extension that does
2922 not contribute to the negotiated metadata can't be served without
2923 an explicit request. E.g., if the .Z extension is associated with
2924 an unzip filter, the user request somefile.Z.html, mod_negotiation
2925 won't serve it. It can serve somefile.Z.html when somefile.Z is
2926 requested, since the .Z extension is explictly requested, if the
2927 .html extension is associated with ContentType text/html.
2930 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
2931 and corresponding AddOutputFilter syntax, to insert one or more
2932 filters by mod_mime filename extension processing.
2935 *) Fix a growing connection pool in core_output_filter() for
2936 keepalive requests. [Jeff Trawick]
2938 *) Moved split_and_pass_pretag_buckets back to being a
2939 macro at Ryans's request. Removed the return from it
2940 by setting and returning a return code instead. Updated
2941 the code to check the return code from the macro and
2942 do the right thing. [Paul J. Reder]
2944 *) Fix a segfault when a numeric value was received for Host:.
2947 *) Add a function ap_remove_input_filter. This is to match
2948 up with ap_remove_output_filter. [Ryan Bloom]
2950 *) Clean up location_walk, so that this step performs a minimum
2951 amount of redundant effort (it must be run twice, but it will no
2952 longer reparse all <Location > blocks when the request uri
2953 hadn't changed.) [William Rowe]
2955 *) Eliminate proxy: (and all other 'special') processing from the
2956 ap_directory_walk() phase. Modules that want to use special
2957 walk logic should refer to the mod_proxy map_to_location example,
2958 with it's proxy_walk and proxysection implementation. This makes
2959 either directory_walk flavor much more legible, since that phase
2960 only runs against real <Directory > blocks.
2963 *) SECURITY: Fix a security problem in mod_include which would allow
2964 an SSI document to be passed to the client unparsed.
2965 [Cliff Woolley, Brian Pane]
2967 *) Introduce the map_to_storage hook, which allows modules to bypass
2968 the directory_walk and file_walk for non-file requests. TRACE
2969 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
2970 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
2973 *) Add the ability for mod_include to add the INCLUDES filter
2974 if the file is configured for the server-parsed handler.
2975 This makes the configuration for .shtml files much easier
2976 to understand, and allows mod_include to honor Apache 1.3
2977 config files. Based on Doug MacEachern's patch to PHP
2978 to do the same thing. [Ryan Bloom]
2980 *) force OpenSSL to ignore process local-caching and to always
2981 get/set/delete sessions using mod_ssl's callbacks
2982 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
2983 Geoff Thorpe <geoff@geoffthorpe.net>]
2985 *) Make the worker MPM shutdown and restart cleanly. This also
2986 cleans up some race conditions, and gets the worker using
2987 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
2989 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
2991 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2993 *) Fix for mod_include. Ryan's patch to check error
2994 codes put a return in the wrong place. Also, the
2995 include handler return code wasn't being checked.
2996 I don't like macros with returns, so I converted
2997 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
2998 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3000 *) fix segv in mod_mime if no AddTypes are configured
3001 [John Sterling <sterling@covalent.net>]
3003 *) Enable ssl client authentication at SSL_accept time
3004 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
3006 *) Fix a segfault in mod_include when the original request has no
3007 associated filename (e.g., we're filtering the error document for
3008 a bad URI). [Jeff Trawick]
3010 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
3012 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
3013 of httpd is started and shuts down due to socket conflict. Moving the
3014 call to ap_log_pid solves the problem.
3016 *) Changed the late-1.3 log_config substitution %c to %X, to log the
3017 status of the closed connection, as it conflicts with the far more
3018 common, historical ssl logging directive %...{var}c. [William Rowe]
3020 *) Added the common error/ tree to the build/install targets
3021 (similar to the common icons/ tree) for the multi-language error
3022 messages that Lars committed earlier. [William Rowe]
3024 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
3026 *) Added a default commented-out mod_ldap and mod_auth_ldap
3027 configuration to httpd-std.conf and httpd-win.conf
3030 *) Added documentation for mod_ldap and mod_auth_ldap.
3033 *) Enabled negative caching on attribute comparisons in the LDAP cache.
3034 Fixed a problem where the default cache TTL was set in milliseconds
3035 not microseconds causing the cache to time out almost immediately.
3038 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
3039 module code to follow APR. [Graham Leggett]
3041 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
3042 cleaned up when the connection pool pool is cleaned up.
3045 *) Fix a minor issue with Jeff Trawick's mod_include
3046 patch. Without this patch, the code will just allocate
3047 more bytes in get_combined_directive than are needed.
3050 *) Added the LDAP authentication module mod_auth_ldap.
3051 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
3053 *) Added the LDAP cache and connection pooling module mod_ldap.
3054 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
3056 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
3057 by allowing a module to disable itself if its prerequisites are not
3058 met. [Justin Erenkrantz]
3060 Changes with Apache 2.0.24
3062 *) Fix a couple of issues in mod_include when the tag appeared at
3063 offsets near 8192 in the file being parsed. [Jeff Trawick]
3065 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
3066 reached. [Jeff Trawick]
3068 *) Numerous improvements to the Win32 build system. Introduced command line
3069 builds without requiring .mak files for MSVC 6.0 and later versions.
3070 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
3073 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
3074 reporting of uninstalled services and other error conditions, and changed the
3075 default service name to Apache2. [William Rowe]
3077 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
3078 compatibility with existing Apache 1.3 Win32 Apache management utilites.
3079 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
3081 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
3082 [William Rowe, Greg Ames]
3084 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
3085 and RemoveCharset directives. [William Rowe]
3087 *) The Unix MPMs other than perchild now allow child server
3088 processes to use the accept mutex when starting as root and
3089 using SysV sems for the accept mutex. Previously, this
3090 combination would lead to fatal errors in the child server
3091 processes. perchild can't use SysV sems because of security
3092 issues. [Jeff Trawick, Greg Ames]
3094 *) Added Win32 revision stamp resources to all http binaries
3095 (including modules/ and support/ tools.) PR7322 [William Rowe]
3097 *) Fix ap_rvprintf to support more than 4K of data at one time.
3098 [Cody Sherr <csherr@covalent.net>]
3100 *) We have always used the obsolete/deprecated Netscape syntax
3101 for our tracking cookies; now the CookieStyle directive
3102 allows the Webmaster to choose the Netscape, RFC2109, or
3103 RFC2965 format. The new CookieDomain directive allows the
3104 setting of the cookie's Domain= attribute, too. PR #s 5006,
3105 5023, 5920, 6140 [Ken Coar]
3107 *) Tweak server/Makefile so that the rules for generating exports.c
3108 are compatible with make utilities which don't expand wildcards
3109 in a dependency list (e.g., OS/390 make, certain levels of GNU
3110 make). [Jeff Trawick]
3112 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
3114 *) Begin to sanitize the MPM configuration directives. Now, all
3115 MPMs use the same functions for all common MPM directives. This
3116 should make it easier to catch all bugs in these directives once.
3117 [Cody Sherr <csherr@covalent.net>]
3119 *) Close a major resource leak. Every time we had issued a
3120 graceful restart, we leaked a socket descriptor.
3123 *) Fix a problem with the new method code. We need to cast
3124 the 1 to an apr_int64_t or it will be treated as a 32-bit
3125 integer, and it will wrap after being shifted 32 times.
3126 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
3128 *) Fix a bug in mod_expires. Previous to this patch, if you
3129 told mod_expires to add 604800 seconds to the last-modified
3130 time, it actually added 604800 usec's to the last-modified time,
3131 so that when looking at the response it looked like nothing
3132 had been done. The root of the problem was that we always compute
3133 time in usec's, but we ask users to input sec's. This means we
3134 need to convert to usec's before using those values.
3137 *) The worker MPM now handles shutdown and restart requests. It
3138 definitely isn't perfect, but we do stop the servers correctly.
3139 The biggest problem right now is that SIGHUP causes the server to
3140 just die. [Ryan Bloom]
3142 Changes with Apache 2.0.23
3144 *) Use the prefork MPM by default on Unix. [various]
3146 *) Added a systray icon monitor application for Win32.
3147 [Mladen Turk <mturk@mappingsoft.com>]
3149 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3150 messages written to the rewrite log.
3151 [Richard Labennett <rlabenn@us.ibm.com>]
3153 *) All mod_autoindex query parsing is now quietly quashed with the
3154 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3155 still drops the column sort <a href>'s for the column headers, but
3156 IgnoreClient is required to ignore these Query options entirely.
3159 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3160 to allow the client to select plain, FancyIndexing or HTMLTable
3161 formatting, V=[0|1] to inhibit or enable version sorting, and
3162 P=pattern to return only specific files. The old Query Arguments
3163 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3164 as before), and O=A|D for ordering ascending or descending.
3167 *) Fixed an error in mod_include's directive parsing routines which
3168 caused #if, #elif, and #else expressions containing backslashes
3169 to be improperly evaluated. [Cliff Woolley]
3171 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3172 drop the icon column, SuppressRules to drop the <hr> elements,
3173 and HTMLTable to create rudimentary HTML table listings (implies
3174 FancyIndexing). [William Rowe]
3176 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3177 from Apache 1.3.15. This is needed for two reasons, first, given
3178 multiple machines within a server farm, ETags and Last-Modified
3179 stamps won't correspond from machine to machine, and second, many
3180 Unixes don't capture changes to the date or time stamp of existing
3181 files, since these don't modify the dirent itself. [William Rowe]
3183 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3184 and DirectoryWidth options from Apache 1.3.10.
3185 [William Rowe, Ken Coar]
3187 *) Eliminated FancyIndexing directive, deprecated early in Apache
3188 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3190 *) mod_autoindex now excludes any file names that would result in
3191 an error, other than a success or redirect. Also optimized
3192 the parent directory, always included except in the URI '/'.
3195 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3196 negotiated index pages, and prevent the server from defaulting
3197 to an autoindex of the directory. mod_negotiation will now die
3198 with a 500 Internal Error if it could match some filenames
3199 (e.g. for mod_dir) but none can be served. mod_negotation now
3200 refuses to serve any file with an extention that mod_mime doesn't
3201 recognize, and wasn't part of the request. [William Rowe]
3203 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3204 extension. This is already handled by multiviews, if the admin
3205 wishes to AddHandler .exe or define a content type handler and
3206 associate .exe files with that content type. Multiviews must be
3207 enabled to allow these to be served. [William Rowe]
3209 *) Speed up the server's response to a spike in incoming workload
3210 or restarts by assigning empty scoreboard slots to new processes
3211 when they are available. [Greg Ames]
3213 *) Add a handler to mod_includes.c. This handler is designed to
3214 implement the XbitHack directive. This can't be done with a
3215 fixup, because we need to check the content-type, which is
3216 only available in the handler phase. [Ryan Bloom]
3218 *) Make the includes filter check return codes from filters lower in
3219 the filter chain. If a lower level filter returns an error, then
3220 the request needs to stop immediately. This allows mod_include to
3221 stop parsing data once a lower filter recognizes an error.
3224 *) Add the ability to extend the methods that Apache understands
3225 and have those methods <limit>able in the httpd.conf. It uses
3226 the same bit mask/shifted offset as the original HTTP methods
3227 such as M_GET or M_POST, but expands the total bits from an int to
3228 an ap_int64_t to handle more bits for new request methods than
3229 an int provides. [Cody Sherr <csherr@covalent.net>]
3231 *) Fix broken mod_mime behavior in merging its arguments. Possible
3232 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
3234 *) Solve many mod_ssl porting issues (too many to detail) with
3235 help from the whole team, but most notably [Ralf S. Engelschall,
3236 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
3237 Doug MacEachern, William Rowe, Cliff Woolley]
3239 *) More stall fixes for the threaded & worker mpm's.
3240 Make mod_status output more accurate. Don't
3241 count workers in processes which aren't actively
3242 serving requests. [Greg Ames]
3244 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
3246 *) Add a single listener/multiple worker MPM. This MPM is
3247 definately not fully correct, but it allows us to solve many
3248 of the problems that exist in the threaded MPM. This is a
3249 modified version of the threaded MPM. [Ryan Bloom]
3251 *) Improve content generation throughout Apache, providing closer
3252 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
3253 Transitional specifications. [William Rowe]
3255 Changes with Apache 2.0.22
3257 *) Fix a problem where the threaded MPM stalls after restarts or
3258 segfaults. Also prevent multiple active processes from using
3259 the same scoreboard slot. [Greg Ames]
3261 *) Apache/Win32 now fills in the service description with Apache's
3262 server version string, including loaded and advertised modules.
3265 *) Improved support for the Win32 build, to recover gracefully from
3266 missing apr or apr-util directories or the awk interpreter,
3267 create the proper cgi-bin examples, including a test-cgi.bat, and
3268 fix the perl shebang line for printenv.pl, when installing from
3269 the build environment. [William Rowe]
3271 *) Fix a segfault in threaded.c caused by passing uninitialized
3272 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
3274 *) Use new APR number conversion functions to reduce CPU consumption
3275 when setting the content length, and in mod_log_config.
3278 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
3279 where HEAD response headers were being repeated twice for
3280 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
3281 problem in the http_header filter was exposed by the recent rewrite
3282 of the content_length filter. [Taketo Kabe, Bill Stoddard]
3284 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
3285 restarts. A garbage pointer to a vhost's server_rec from the
3286 previous generation was being left around under certain
3287 conditions. [Greg Ames]
3289 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
3290 used to appear as '(none', without the closing paren.
3291 [Günter Knauf <eflash@gmx.net>]
3293 *) Improve the exports generating awk script. In the past, we had
3294 work around problems in the awk script by avoiding some #if and
3295 #ifdefs. This has bitten us many times in generating the exports.c
3296 file. This improvement allows corrects the header file parsing.
3297 [Sander Striker <striker@apache.org>]
3299 Changes with Apache 2.0.21
3301 *) Resolve the Win32 htpasswd bug, where a file that existed would be
3302 overwritten, regardless of the -c flag.
3303 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
3305 *) Introduce connection sub-pools into ab. Truncating the lifetime
3306 of these allocations means that ab no longer perpetually grows
3307 its working set, running out of memory on large request attempts.
3310 *) Make scoreboard creation a hook. This allows management
3311 modules to have access to the scoreboard at the time that it is
3312 created, and at every restart request.
3313 [Cody Sherr <csherr@covalent.net>]
3315 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
3316 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
3317 daemon index actually used in the scoreboard. I also
3318 updated the pertinent calls. [Paul J. Reder]
3320 *) Win32: Prevent listening sockets from being inherited by
3321 the Apache child process, CGI scripts, rotatelog process
3322 etc. If the Apache child process segfaults, any processes
3323 that the child started are not reaped. Prior to this fix,
3324 these processes inherited the listening sockets which sometimes
3325 prevented the restarted Apache child process from accepting
3326 connections (ie, the server would hang).
3329 *) Provide vhost and request strings when ExtendedStatus is on.
3332 *) Fix some issues with the pod and prefork: check the pod *after*
3333 processing a connection so that a server processing a time-
3334 consuming request bails out as soon as practical; when the
3335 parent process wakes up a server process via connect(), use an
3336 APR timeout on the connect() so that we don't hang for a long
3337 time if there aren't server processes around to do accept().
3338 [Jeff Trawick, Greg Ames]
3340 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
3341 spends a lot of time in apr_table_get calls. Using the default
3342 httpd.conf, the tables for languages and charsets are somewhat
3343 large, so the time spent scanning them on each request is
3344 significant. Replacing the tables with hash tables provides
3345 a nice speedup. [Brian Pane <bpane@pacbell.net>]
3347 *) Add two functions to allow modules to access random parts of the
3348 scoreboard. This allows modules compiled for one MPM to access the
3349 scoreboard, even if it the server was compiled for another MPM.
3350 [Harrie Hazewinkel <harrie@covalent.net>]
3352 Changes with Apache 2.0.20
3354 *) Fix problem in content-length filter where the filter would
3355 buffer all the output from a CGI before sending any bytes
3356 down the filter stack to the network. This problem would cause
3357 significant memory consumption if the CGIs generated
3358 lots of bytes. [Bill Stoddard]
3360 *) Get non-blocking CGI pipe reads working with the bucket brigades.
3363 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
3366 *) Fix a bug in the threaded MPM that would cause it to kill off all
3367 workers immediately after starting if the number of workers started
3368 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
3370 Changes with Apache 2.0.19
3372 *) Fix problem with threaded MPM. The problem was that if each child
3373 process was busy serving a single long-lived request and the server
3374 was sent a graceful restart signal, the server would stop serving
3375 requests. This would happen because each child process would wait to
3376 die until the last thread was done, and the parent wouldn't spawn any
3377 new children until a process died. Now, the parent looks at the fact
3378 that the children are dying gracefully, and starts new children.
3379 Those new children only start enough threads to compliment the number
3380 of threads in the other child process that shares the same spot in
3381 the scoreboard. In this way, we make sure to never go over
3382 MaxClients. [Ryan Bloom]
3384 *) modified mod_negotiation and mod_autoindex to speed up by almost a
3385 factor of two on apr_dir_read()-enhanced platforms, such as Win32
3386 and OS2, by calling ap_sub_request_lookup_dirent() with the results
3387 already provided by apr_dir_read(). [William Rowe]
3389 *) mod_file_cache is now more robust to filtering and serves requests
3390 slightly more efficiently. [Cliff Woolley]
3392 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
3393 Module was calling ap_rwrite() followed by ap_rflush() but the
3394 served content was not being displayed in the browser. Inspection
3395 of the output stream revealed that the first data chunk was
3396 missing the trailing CRLF required by the RFC. [Bill Stoddard]
3398 *) apxs no longer generates ap_send_http_header() in the example handler
3400 *) Fix an ab problem which could cause a divide-by-zero exception
3401 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
3402 [Ian Holsman <ianh@cnet.com>]
3404 *) Solve case-insensitive platforms' confusion about negotiated
3405 filenames, allowing files of differnt case to match in choosing
3406 the document to serve. [William Rowe]
3408 *) Fix brokenness when ThreadsPerChild is higher than the built-in
3409 limit. We left ap_threads_per_child at the higher value which
3410 led to segfaults when doing certain scoreboard operations.
3413 *) Fix seg faults and/or missing output from mod_include. The
3414 default_handler was using the subrequest pool for files and
3415 MMAPs, even though the associated APR structures typically
3416 live longer than the subrequest. [Greg Ames]
3418 *) Extend mod_setenvif to support specifying regular expressions
3419 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
3420 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
3421 will cause HAVE_TS to be set if any of the request headers begins
3422 with "TS" and has a value that begins with any character in the
3423 set [a-z]. [Bill Stoddard]
3425 *) httpd children now re-bind themselves to a random CPU on
3426 multiprocessor systems on AIX via bindprocessor() in 2.0.
3427 [Victor J. Orlikowski]
3429 *) Fix htdigest. It would go into a loop in getline when adding
3430 a second user. [Bill Stoddard]
3432 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
3434 *) Automatically generate httpd.exp for AIX.
3435 DSOs now work again on AIX in 2.0
3436 [Victor J. Orlikowski]
3438 *) Add a new request hook, error_log. This phase allows modules
3439 to act on the error log string _after_ it has been written
3440 to the error log. The goal for this hook is to allow monitoring
3441 modules to send the error string to the monitoring agent.
3444 *) Modify mod_echo to make it use filters for input and output.
3445 [Ryan Morgan <rmorgan@covalent.net>]
3447 *) Extend mod_headers to support conditional driven Header
3448 add, append and set. Use SetEnvIf to set an envar and conditionally
3449 add/append/set headers based on this envar thusly:
3451 SetEnvIf TSMyHeader value HAVE_TSMyHeader
3452 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
3454 If the request contains header "TSMyHeader: value" then header
3455 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
3458 *) Extend mod_headers to support using format specifiers on Header
3459 add, append and set header values. Two format specifiers are supported:
3461 %t - reports, in UTC microseconds since the epoch, when the
3462 request was received.
3464 %D - reports the time, in microseconds, between when the request was
3465 received and the response sent.
3468 Header add MyHeader "This request served in %D microseconds. %t"
3470 results in a header being added to the response that looks like this:
3472 MyHeader: This request served in D=5438 microseconds. t=991424704447256
3476 *) Fix reset_filter(). We need to be careful how we remove filters.
3477 If we set r->output_filters to NULL, we also have to reset the
3478 connection's filters. [John Sterling]
3480 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
3482 *) Add a check to ap_die() to make sure the filter stack is sane and
3483 contains the correct basic filters when an error occurs. This fixes
3484 a problem where headers are not being sent on error. [John Sterling]
3486 *) New Header directive 'echo' option. "Header echo regex" will
3487 cause any headers received on the request that match regex to be
3488 echoed to (included in) the response headers.
3491 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
3492 This prevented the inclusion of apr_compat.h. PR #7773
3493 [Oleg Broytmann <phd@phd.pp.ru>]
3495 *) Moved util_uri to the apr-util library. This required a bunch of
3496 apr_name changes for the uri utility functions. [Justin Erenkrantz]
3498 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
3499 insert_filter phase so that other filters are not bypassed by default.
3502 *) Reimplement mod_headers as an output filter. mod_headers can now
3503 add custom headers to inbound requests using the RequestHeader directive
3504 and to responses using the same old Header directive. [Graham Leggett]
3506 Changes with Apache 2.0.18
3508 *) Fix command-line processing so that if a bad argument is specified
3509 Apache will exit. [Jeff Trawick]
3511 *) Change the make targets and rules to be consistent in all of the
3512 Apache-owned source trees. [Roy Fielding]
3514 *) Fix processing of the TRACE method. Previously we passed bogus
3515 parms to form_header_field() and it overlaid some vhost structures,
3516 resulting in a segfault in check_hostalias().
3517 [Greg Ames, Jeff Trawick]
3519 *) Win32: Add support for reliable piped logs. If the logging process
3520 goes down, Apache will automatically restart it. This function has
3521 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
3524 *) Do not start piped log processes during the config file
3525 preflight. This change also circumvents a problem on
3526 Windows where the rotatelog processes created during preflight
3527 was not getting cleaned up properly.
3530 *) add "Request Phase Participation" info to mod_info
3533 *) Make first phase changes to the scoreboard data structures in
3534 preparation for the rewriting of the scoreboard per my posted
3535 design notes. [Paul J. Reder]
3537 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
3538 and apr-util, allow it to be overridden by the configure command-line
3539 (default="--silent") and introduce LT_LDFLAGS to replace what we were
3540 formerly abusing as LTFLAGS. [Roy Fielding]
3542 *) Clean up the reporting of incorrect closing container tags.
3543 [Barrie Slaymaker <barries@slaysys.com>]
3545 *) Simplify the configure process by moving all libtool stuff to APR
3546 and moving hints.m4 inline. [Roy Fielding]
3548 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
3549 of functions used by mod_proxy for export in the DLL
3550 [Ian Holsman <IanH@cnet.com>]
3552 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
3553 request body from its stdin but no reqest body is being written to
3554 the cgi. [Jeff Trawick]
3556 *) mod_log_config: %c connection status incorrectly logged
3557 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
3560 *) Get mod_cern_meta working under Windows
3563 *) Create Files, and thus MMAPs, out of the request pool, not the
3564 connection pool. This solves a small resource leak that had us
3565 not closing files until a connection was closed. In order to do
3566 this, at the end of the core_output_filter, we loop through the
3567 brigade and convert any data we have into a single HEAP bucket
3568 that we know will survive clearing the request_rec.
3569 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
3572 *) Completely revamp configure so that it preserves the standard make
3573 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
3574 the configure additions to EXTRA_* variables. Also, allow the user
3575 to specify NOTEST_* values for all of the above, which eliminates the
3576 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
3577 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
3578 avoid pointless duplications. Fix the order in which flags are given
3579 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
3580 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
3581 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
3582 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
3584 *) Get mod_tls to compile/work better on Windows. PR #7612
3585 [Bernhard Schrenk <b.schrenk@improx.com>]
3587 *) Fix shutdown/restart hangs in the threaded MPM.
3588 [Jeff Trawick, Greg Ames, Ryan Bloom]
3590 *) Removed the keptalive boolean from conn_rec because it is now only
3591 used by a single routine and can be replaced by a local variable.
3592 [Greg Stein, Ryan Bloom, Roy Fielding]
3594 *) Patch prefork to put enough of the signal processing back in so that
3595 signals are all handled properly now. The previous patch fixed the
3596 deadlock race condition, but broke the user directed signal handling.
3597 This fixes it to work the way it did before my previous prefork patch
3598 (primarily, SIGTERM is now working).
3600 *) Change how input filters decide how much data is returned to the
3601 higher filter. We used to use a field in the conn_rec, with this
3602 change, we use an argument to ap_get_brigade to determine how much
3603 data is retrieved. [Ryan Bloom]
3605 *) Fix seg fault at start-up introduced by Ryan's change to enable
3606 modules to specify their own logging tags. mod_log_config
3607 registers an optional function, ap_register_log_handler().
3608 ap_register_log_handler() was being called by http_core before
3609 the directive hash table was created. This patch creates the
3610 directive hash table before ap_register_log_handler() is
3611 registered as an optional function.
3612 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
3614 *) Add ap_set_int_slot() function
3615 [John K. Sterling <sterling@covalent.net>]
3617 *) Under certain circumstances, Apache did not supply the
3618 right response headers when requiring authentication.
3619 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
3620 (This is a port of the change that went into Apache 1.3.19.)
3622 *) Allow modules to specify their own logging tags. This basically
3623 allows a module to tell mod_log_config that when %x is encountered
3624 a specific function should be called. Currently, x can be any single
3625 character. It may be more useful to make this a string at some point.
3628 Changes with Apache 2.0.17
3630 *) If a higher-level filter handles the the byterange aspects of a
3631 request, then the byterange filter should not try to redo the
3632 work. The most common case of this happening, is a byterange
3633 request going through the proxy, and the origin server handles
3634 the byterange request. The proxy should ignore it.
3635 [Graham Leggett <minfrin@sharp.fm>]
3637 *) Changed the threaded mpm to have child_main join to each of the
3638 worker threads to make sure the kids are all gone before child_main
3639 exits after a signal (cleanup from perform_idle_server_maintenance).
3640 This is an extension of Ryans recent commit to make the child_main
3643 *) Add more options to the ap_mpm_query function. This also allows MPMs to
3644 report if their threads are dynamic or static. Finally, this also
3645 implements a new API, ap_show_mpm, which returns the MPM that was
3646 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
3648 *) Do not install the binaries from the support directory twice.
3649 [jun-ichiro hagino <itojun@iijlab.net>]
3651 *) The ap_f* functions should flush data to the filter that is passed
3652 in, not the the filter after the one passed in.
3653 [Ryan Morgan <rmorgan@covalent.net>]
3655 *) Make ab work again by changing its native types to apr types and formats.
3656 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3658 *) Move the byterange filter and all of the supporting functions back
3659 to the HTTP module. The byterange filter turned out to be very
3660 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
3662 *) Make clean, distclean, and extraclean consistently according to the
3663 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3665 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
3666 This may have been causing problems stopping processes in the threaded
3669 *) Fix content-length in mod_negotiation to a long int representation.
3672 *) Remove BindAddress from the default config file.
3673 [giles@nemeton.com.au]
3675 *) Allow module authors to add a module to their Apache build using
3676 --with-module, without re-running buildconf. The syntax is:
3677 --with-module=module_type:/path/to/module.c
3678 The configure script will copy the module.c file to
3679 modules/module_type, and it will be added to the relevant Makefiles.
3680 currently, this only works for static modules. [Ryan Bloom]
3682 *) Changes required to make prefork clean up idle children properly.
3683 There was a window during which a starting worker deadlocks when
3684 an idle cleanup arrives before it completes init. Apache then keeps
3685 trying to cleanup the same deadlocked worker forever (until higher
3686 pids come along, but it still will never reduce below the deadlocked
3687 pid). Thus the number of children would not reduce to the correct
3688 idle level. [Paul J. Reder]
3690 Changes with Apache 2.0.16
3692 *) Change the default installation directory to /usr/local/apache2,
3693 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
3695 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
3698 *) Get MaxRequestsPerChild working with the Windows MPM.
3701 *) Make generic hooks to work, with mod_generic_hook_import/export
3702 experimental modules. [Ben Laurie, Will Rowe]
3704 *) Fix segfaults for configuration file syntax errors such as
3705 "<Directory>" followed by "</Directory" and
3706 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
3708 *) Cleanup the --enable-layout option of configure. This makes
3709 us use a consistent location for the config.layout file, and it
3710 makes configure more portable.
3711 [jun-ichiro hagino <itojun@iijlab.net>]
3713 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
3714 csv/gnuplot format, rudimentary ssl support and various other tweaks
3715 to make results more true to what is measured. The upshot of this it
3716 turns out that 'ab' has often underreported the true performance of
3717 apache. Often by a order of magnitude :-) See talk/paper of Sander
3718 Temme at April ApacheCon 2001 for details.
3719 [Dirk-Willem van Gulik]
3721 *) Clean up mod_cgid's temporary request pool. Besides fixing a
3722 storage leak this ensures that some unnecessary pipes are closed.
3725 *) Performance: Add quick_handler hook. This hook is called at the
3726 very beginning of the request processing before location_walk,
3727 translate_name, etc. This hook is useful for URI keyed content
3728 caches like Mike Abbott's Quick Shortcut Cache.
3731 *) top_module global variable renamed to ap_top_module [Perl]
3733 *) Move ap_set_last_modified to the core. This is a potentially
3734 controversial change, because this is kind of HTTP specific. However
3735 many protocols should be able to take advantage of this kind of
3736 information. I expect that headers will need one more layer of
3737 indirection for multi-protocol work, but this is a small step in
3738 the right direction. [Ryan Bloom]
3740 *) Enable mod_status by default. This matches what Apache 1.3 does.
3743 *) Add a ScriptSock directive to the default config file. This is
3744 only enabled when mod_cgid is used.
3745 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3747 Changes with Apache 2.0.15
3749 *) Untangled the buildconf script and eliminated the need for build's
3750 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
3751 libtool muck that is now under srclib/apr/build. [Roy Fielding]
3753 *) Win32: Don't accept more connections than we have worker threads
3757 *) Fix bug in the Unix threaded.c MPM that allowed child processes
3758 to fork() new child processes.
3761 *) SECURITY: Fix a major security problem with double-reverse lookup
3762 checking. Previously, a client connecting over IPv4 would not be
3763 matched properly when the server had an IPv6 listening socket.
3764 PR #7407 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
3766 *) Change the way the beos MPM handles polling to allow it to stop and
3767 restart. Problem was the sockets being polled were being reset by
3768 the select call, so once it had accepted a connection it was no
3769 longer listening on the UDP socket we use for shutdown instructions.
3770 APR needs to be altered, patch on it's way. [David Reid]
3772 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
3773 on error exit from ap_getline(). Some other code got upset because
3774 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
3776 *) Handle ap_discard_request_body() being called more than once.
3777 [Greg Ames, Jeff Trawick]
3779 *) Get rid of an inadvertent close of file descriptor 2 in
3780 mod_mime_magic. [Greg Ames, Jeff Trawick]
3782 *) Add a hook, create_request. This hook allows modules to modify
3783 a request while it is being created. This hook is called for all
3784 request_rec's, main request, sub request, and internal redirect.
3785 When this hook is called, the the r->main, r->prev, r->next
3786 pointers have been set, so modules can determine what kind of
3787 request this is. [Ryan Bloom]
3789 *) Cleanup the build process a bit more. The Apache configure
3790 script no longer creates its own helper scripts, it just
3792 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
3794 *) Stop the forced downgrade of the connection to HTTP/1.0 for
3795 proxy requests. [Graham Leggett]
3797 *) Avoid using sscanf to determine the HTTP protocol number in
3798 the common case because sscanf is a performance hog. From
3799 Mike Abbot's Accelerating Apache patch number 6.
3800 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
3802 *) SECURITY: Fix a security exposure in mod_access. Previously when
3803 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
3804 were not evaluated properly (PR #7407). Also, add the ability to
3805 specify IPv6 address strings with optional prefix length on Allow
3806 and Deny. [Jeff Trawick]
3808 *) Enhance rotatelogs so that a UTC offset can be specified, and
3809 the logfile name can be formatted using strftime(3). (Brought
3810 forward from 1.3.) [Ken Coar]
3812 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
3813 DuplicateHandle on an IOCompletionPort (a practice which
3814 MS "discourages"). The new model does not rely on associating
3815 the completion port with the listening sockets, thus the
3816 completion port can be completely managed within the child
3817 process. A dedicated thread accepts connections off the network,
3818 then calls PostQueuedCompletionStatus() to wake up worker
3819 threads blocked on the completion port.
3822 *) Bring forward the --suexec-umask option which allows the
3823 builder to preset the umask for suexec processes. [Ken Coar]
3825 *) Add a -V flag to suexec, which causes it to display the
3826 compile-time settings with which it was built. (Only
3827 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
3829 *) Mod_include should always unset the content-length if the file is
3830 going to be passed through send_parsed_content. There is no to
3831 determine if the content will change before actually scanning the
3832 entire content. It is far safer to just remove the C-L as long
3833 as we are scanning it. [Ryan Bloom]
3835 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
3836 request and not Proxy-Authenticate.
3837 [Graham Leggett <minfrin@sharp.fm>]
3839 Changes with Apache 2.0.14
3841 *) Fix content-length computation. We ONLY compute a content-length if
3842 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
3843 or we already have all the data. [Ryan Bloom]
3845 *) Report unbounded containers in the config file. Previously, a typo
3846 in the </container> directive could result in the rest of the config
3847 file being silently ignored, with undesired defaults used.
3850 *) Make the old_write filter use the ap_f* functions for the buffering.
3853 *) Move more code from the http module into the core server. This
3854 is core code, basically the default handler, the default input
3855 and output filters, and all of the core configuration directives.
3856 All of this code is required in order for the server to work, with or
3857 without HTTP. The server is closer to working without the HTTP
3858 module, although there is still more to do. [Ryan Bloom]
3860 *) Fix a number of SGI compile warnings throughout the server. Fix some
3861 bad parameters to apr_bucket_read(). Fix a bad statement in
3862 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
3863 consistently; we were mixing apr_time_t and time_t in invalid ways
3864 before. In load_file(), call apr_dso_error() instead of
3865 apr_strerror() so that we get a more specific string on some platforms.
3866 PR #6980 [Jeff Trawick]
3868 *) Allow modules to query the MPM about it's execution profile. This
3869 query API can and should be extended in the future, but for now,
3870 max_daemons, and threading or forking is a very good start.
3871 [Jon Travis <jtravis@covalent.net>]
3873 *) Modify mod_include to send blocks of data no larger than 9k.
3874 Without this, mod_include will wait until the whole file is parsed,
3875 or the first tag is found to send any data to the client.
3876 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3878 *) Fix mod_info, so that <Directory> and <Location> directives are
3879 not displayed twice when displaying the current configuration.
3880 [Ryan Morgan <rmorgan@covalent.net>]
3882 *) Add config directives to override DEFAULT_ERROR_MSG and
3883 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
3884 [Dan Rench <drench@xnet.com>]
3886 *) Get mod_info building and loading on Win32. [William Rowe]
3888 *) Begin to move protocol independant functions out of mod_http. The goal
3889 is to have only functions that are HTTP specific in the http directory.
3892 Changes with Apache 2.0.13
3894 *) Don't assume that there will always be multiple calls to the byterange
3895 filter. It is possible that we will need to do byteranges with only
3896 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
3898 *) Move the error_bucket definition from the http module to the
3899 core server. Every protocol will need this ability, not just
3902 Changes with Apache 2.0.12
3904 *) Modify mod_file_cache to save pre-formatted strings for
3905 content-length and last-modified headers for performance.
3906 [Mike Abbot <mja@trudge.engr.sgi.com>]
3908 *) Namespace protect IOBUFSIZ since it is exposed in the API.
3909 [Jon Travis <jtravis@covalent.net>]
3911 *) Use "Basic" authentication instead of "basic" in ab, as the spec
3912 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
3914 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
3915 without ever filling it out. This fixes PR 7271.
3916 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
3917 Cliff Woolley <cliffwoolley@yahoo.com>]
3919 *) Add a couple of GCC attribute tags to printf style functions.
3920 [Jon Travis <jtravis@covalent.net>]
3922 *) Add the correct language tag for interoperation with the Taiwanese
3923 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
3925 *) Migrate the perchild MPM to use the new apr signal child, and
3926 APR thread functions. [Ryan Bloom]
3928 *) Close one copy of the CGI's stdout before creating the new process.
3929 The CGI will still have stdout, because we have already dup'ed it.
3930 This keeps Apache from waiting forever to send the results of a CGI
3931 process that has forked a long-lived child process.
3932 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3934 *) Remove the rest of the pthreads functions from the threaded MPM.
3935 This requires the APR support for a signal thread that was just
3938 *) Make mod_dir use a fixup for sending a redirect to the browser.
3939 Before this, we were using a handler, which doesn't make much
3940 sense, because the handler wasn't generating any data, it would
3941 either return a redirect error code, or DECLINED. This fits the
3942 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
3944 *) Make the threaded MPM use APR threads instead of pthreads.
3947 *) Get mod_tls to the point where it actually appears to work in all cases.
3950 *) implement --enable-modules and --enable-mods-shared for "all" and
3951 "most". [Greg Stein]
3953 *) Move the threaded MPM to use APR locks instead of pthread locks.
3956 *) Rename mpmt_pthread to threaded. This is more in line with the
3957 fact that mpmt_pthread shouldn't be using pthreads directly, and
3958 it is a smaller name that doesn't tie into anything.
3961 *) Rename the module structures so that the exported symbol matches
3962 the file name, and it is easier to automate the installation
3963 process (generating LoadModule directives from the module filenames).
3966 *) Remove the coalesce filter. With the ap_f* functions, this filter
3967 is no longer needed. [Ryan Bloom]
3969 Changes with Apache 2.0.11
3971 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
3972 added feature of allowing a uid/gid per child process. If no
3973 uid/gid is specified, then Perchild behaves exactly like dexter.
3976 *) Get perchild building again. [Ryan Bloom]
3978 *) Don't disable threads just because we are using the prefork MPM.
3979 If somebody wants to compile without threads, they must now add
3980 --disable-threads to the configure command line. [Ryan Bloom]
3982 *) Begin to move the calls to update_child_status into common code, so
3983 that each individual MPM does not need to update the scoreboard itself.
3986 *) Allow mod_tls to compile under Unix boxes where openssl has been
3987 installed to the system include files.
3988 [Gomez Henri <new-httpd@slib.fr>]
3990 *) Cleanup the mod_tls configure process. This should remove any need
3991 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
3992 configure doesn't check that yet. [Ryan Bloom]
3994 *) Add a very early prototype of SSL support (in mod_tls.c). It is
3995 vital that you read modules/tls/README before attempting to build
3998 *) Fix a potential seg fault on all platforms. David Reid fixed this
3999 on BEOS, but the problem could happen anywhere, so we don't want
4000 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
4002 *) Add new LogFormat directive, %D, to log time it takes to serve a
4003 request in microseconds. [Bill Stoddard]
4005 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
4006 SetOutputFilter. This corresponds nicely with the other Set
4007 directives, which operate on containers while the Add* directives
4008 tend to work directly on extensions. [Ryan Bloom]
4010 *) Cleanup the header handling a bit. This uses the apr_brigade_*
4011 functions for the buffering so that we don't need to compute
4012 the length of the headers before we actually create the header
4013 buffer. [Ryan Bloom]
4015 *) Allow filters to buffer data using the ap_f* functions. These have
4016 become macros that resolve directly to apr_brigade_*.
4019 *) Get the Unix MPM's to do a graceful restart again. If we are going
4020 to register a cleanup with ap_cleanup_scoreboard, then we have to
4021 kill the cleanup with the same function, and that function can't be
4022 static. [Ryan Bloom]
4024 *) Install all required header files. Without these, it was not
4025 possible to compile some modules outside of the server.
4028 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
4029 forward from 1.3 to 2.0, we missed a single line, which broke regex
4030 aliases. [Ryan Bloom]
4032 *) We have a poor abstraction in the protocol. This is a temporary
4033 hack to fix the bug, but it will need to be fixed for real. If
4034 we find an error while sending out a custom error response, we back
4035 up to the first non-OK request and send the data. Then, when we send
4036 the EOS from finalize_request_protocol, we go to the last request,
4037 to ensure that we aren't sending an EOS to a request that has already
4038 received one. Because the data is sent on a different request than
4039 the EOS, the error text never gets sent down the filter stack. This
4040 fixes the problem by finding the last request, and sending the data
4041 with that request. [Ryan Bloom]
4043 *) Make the server status page show the correct restart time, and
4044 thus the proper uptime. [Ryan Bloom]
4046 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
4047 should reduce the amount of duplicate code that is required to
4048 create CGI processes.
4049 [Paul J. Reder <rederpj@raleigh.ibm.com>]
4051 *) ap_new_connection() closes the socket and returns NULL if a socket
4052 call fails. Usually this is due to a connection which has been
4053 reset. [Jeff Trawick]
4055 *) Move the Apache version information out of httpd.h and into release.h.
4056 This is in preparation for the first tag with the new tag and release
4057 system. [Ryan Bloom]
4059 *) Begin restructuring scoreboard code to enable adding back in
4060 the ability to use IPC other than shared memory.
4061 Get mod_status working on Windows again. [Bill Stoddard]
4063 *) Make mod_status work with 2.0. This will work for prefork,
4064 mpmt_pthread, and dexter. [Ryan Bloom]
4066 *) Correct a typo in httpd.conf.
4067 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
4069 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
4071 *) Get the correct IP address if ServerName isn't set and we can't
4072 find a fully-qualified domain name at startup.
4073 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
4075 *) Make mod_cgid work with SuExec. [Ryan Bloom]
4077 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
4078 'extra' stat's for user/group since they should never occur, and now
4079 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
4080 volumes. [William Rowe]
4082 *) Adopt apr features to simplify mod_includes. This changes the
4083 behavior of the USER_NAME variable, unknown uid's are now reported
4084 as USER_NAME="<unknown>" rather than the old user#000 result.
4085 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
4087 *) Adopt apr features for simplifing mod_userdir, and accept the new
4088 Win32/OS2 exceptions without hiccuping. [William Rowe]
4090 *) Replace configure --with-optim option by using and saving the
4091 environment variable OPTIM instead. This is needed because configure
4092 options do not support multiple flags separated by spaces.
4095 *) Fix some byterange handling. If we get a byte range that looks like
4096 "-999999" where that is past the end of the file, we should return
4097 a PARTIAL CONTENT status code, and return the whole file as one big
4098 byterange. This matches the 1.3 handling now. [Ryan Bloom]
4100 *) Make the error bucket a real meta-data bucket. This means that the
4101 bucket length is 0, and a read returns NULL data. If one of these
4102 buckets is passed down after the headers are sent, this data will
4103 just be ignored. [Greg Stein]
4105 *) The prefork MPM wasn't killing child processes correctly if a restart
4106 signal was received while the process was serving a request. The child
4107 process would become the equivalent of a second parent process. If
4108 we break out of the accept loop, then we need to do die after cleaning
4109 up after ourselves. [Ryan Bloom]
4111 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
4112 restarts. [Ryan Bloom]
4114 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
4115 the most optimal APR_FINFO_wanted bits. This spares Win32 from
4116 performing very expensive owner, group and permission lookups
4117 and allows the server to function until these apr_finfo_t fields
4118 are implemented under Win32. [William Rowe]
4120 *) Support for typedsafe optional functions - that is functions exported by
4121 optional modules, which, therefore, may or may not be present, depending
4122 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
4123 for sample code. [Ben Laurie]
4125 *) filters can now report an HTTP error to the server. This is done
4126 by sending a brigade where the first bucket is an error_bucket.
4127 This bucket is a simple bucket that stores an HTTP error and
4128 a string. Currently the string is not used, but it may be needed
4129 to output an error log. The http_header_filter will find this
4130 bucket, and output the error text, and then return
4131 AP_FILTER_ERROR, which informs the server that the error web page
4132 has already been sent. [Ryan Bloom]
4134 *) If we get an error, then we should remove all filters except for
4135 those critical to serving a web page. This fixes a bug, where
4136 error pages were going through the byterange filter, even though
4137 that made no sense. [Ryan Bloom]
4139 *) Relax the syntax checking of Host: headers in order to support
4140 iDNS. PR#6635 [Tony Finch]
4142 *) Cleanup the byterange filter to use the apr_brigade_partition
4143 and apr_bucket_copy functions. This removes a lot of very messy
4144 code, and hopefully makes this filter more stable.
4147 *) Remove AddModule and ClearModuleList directives. Both of these
4148 directives were used to ensure that modules could be enabled
4149 in the correct order. That requirement is now gone, because
4150 we use hooks to ensure that modules are in the correct order.
4153 *) When SuExec is specified, we need to add it to the list of
4154 targets to be built. If we don't, then any changes to the
4155 configuration won't affect SuExec, unless 'make suexec' is
4156 specifically run. [Ryan Bloom]
4158 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4159 the APR_XTHREAD argument to open a file for consumption by
4160 parallel threads on win32. [William Rowe]
4162 *) Correct a bug in determining when we follow symlinks. The code
4163 expected a stat -1 result, not an apr_status_t positive error.
4164 Also check if the APR_FINFO_USER fields are valid before we
4165 follow the link. [William Rowe]
4167 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4168 mpm_common.c. These functions are only valid on some platforms,
4169 so they should not be in the main-line code. [Ryan Bloom]
4171 *) Remove ap_chdir_file(). This function is not thread-safe,
4172 and nobody is currently using it. [Ryan Bloom]
4174 *) Do not try to run make depend if there are no .c files in the
4175 current directory, doing so makes `make depend` fail.
4178 *) Update highperformance.conf to work with either prefork or
4179 pthreads mpms. [Greg Ames]
4181 *) Stop checking to see if this is a pipelined request if we know
4182 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4183 This keeps us from making an extra read call when serving a 1.0
4184 request. [Ryan Bloom and Greg Stein]
4186 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4187 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4188 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4190 *) Fix the RFC number mentioned when complaining about a missing
4191 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
4193 *) Fix an endless loop in ab which occurred when ab was posting
4194 and the server dropped the connection unexpectedly.
4197 *) Fix a segfault while handling request bodies in ap_http_filter().
4198 This problem has been seen with mod_dav usage as well as with
4199 requests where the body was just being discarded. [Jeff Trawick]
4201 *) Some adjustment on the handling and automatic setting (via
4202 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4203 add the capability to specify flags (NOTEST_CFLAGS and
4204 NOTEST_LDFLAGS) which are used to compile Apache, but
4205 not used during the configuration process. Useful for
4206 flags like "-Werror". [Jim Jagielski]
4208 *) Stop using environment variables to force debug mode or
4209 no detach. We now use the -D command line argument to
4210 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4211 [Greg Stein, Ryan Bloom]
4213 *) Change handlers to use hooks. [Ben Laurie]
4215 *) Stop returning copies of filenames from both apr_file_t and
4216 apr_dir_t. We pstrdup the filenames that we store in the
4217 actual structures, so we don't need to pstrdup the strings again.
4220 *) mod_cgi: Fix some problems where the wrong error value was being
4221 traced. [Jeff Trawick]
4223 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
4226 *) Add generic hooks. [Ben Laurie]
4228 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
4230 *) Fix a segfault caused by mod_ext_filter when the external filter
4231 program does not exist. [Jeff Trawick]
4233 *) Fix an output truncation error when on an HTTP >= 1.0 request an
4234 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
4235 was served through mod_charset_lite (or anything else that would
4236 create a transient bucket in this size range). ap_bucket_make_heap()
4237 silently failed (fixed), transient_setaside() discovered it, but
4238 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
4240 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
4241 is that some browsers send extra lines at the end of POST requests, and
4242 we don't want to delay sending data back to the user just because the
4243 browser isn't well behaved. [Ryan Bloom]
4245 *) Get SuEXEC working again. We can't send absolute paths to suExec
4246 because it refuses to execute those programs. SuEXEC also wasn't
4247 always recognizing configuration changes made using the autoconf
4250 *) Allow the buildconf process to find the config.m4 files in the correct
4251 order. Basically, we can now name config.m4 files as config\d\d.m4,
4252 and we will sort them correctly when inserting them into the build
4253 process. [Ryan Bloom]
4255 *) Get mod_cgid to use apr calls for creating the actual CGI process.
4256 This also allows mod_cgid to use ap_os_create_priviledged_process,
4257 thus allowing for SuExec execution from mod_cgid. Currently, we do
4258 not support everything that standard SuExec supports, but at least
4259 it works minimally now. [Ryan Bloom]
4261 *) Allow SuExec to be configured from the ./configure command line.
4264 *) Update some of the docs in README and INSTALL to reflect some of
4265 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
4267 *) If we get EAGAIN returned from the call to apr_sendfile, then we
4268 need to call sendfile again. This gets us serving large files
4269 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
4271 *) Get the support programs building cleanly again.
4272 [Cliff Woolley <cliffwoolley@yahoo.com>]
4274 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
4275 current directory logic now backs up over bin/ to determine the
4276 server root from the Apache.exe path.
4278 *) Apache/Win32 now follows the standard conventions of mod_foo.so
4279 loadable modules, dynamic libs are all named libfoo.dll, and the
4280 makefile.win populates the include, lib and libexec directories.
4282 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
4283 Apache gets IPv6 listening sockets by default. Additionally, the
4284 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
4285 numeric address strings (e.g., "Listen [fe80::1]:8080").
4288 *) Modify the install directory layout. Modules are now installed in
4289 modules/. Shared libraries should be installed in libraries/, but
4290 we don't have any of those on Unix yet. All install directories
4291 are modifyable at configure time. [Ryan Bloom]
4293 *) Install all header files in the same directory on Unix. [Ryan Bloom]
4295 *) Get the functions in server/linked into the server, regardless of
4296 which modules linked into the server. This uses the same hack
4297 for Apache that we use for APR and apr-util to ensure all of the
4298 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
4299 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
4300 the scripts a bit easier.
4303 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
4304 on the query, and remove IPv4 dependencies. [Jeff Trawick]
4306 *) Get all of the auth modules to the point that they will install and
4307 be loadable into the server. Our new build/install mechanism expects
4308 that all modules will have a common name format. The auth modules
4309 didn't use that format, so we didn't install them properly.
4312 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
4313 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
4315 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
4317 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
4318 after the end of the response. [Ryan Bloom]
4320 *) Get byterange requests working with responses that do not have a
4321 content-length. Because of the way byterange requests work, we have to
4322 have all of the data before we can actually do the byterange, so we
4323 can compute the content-length in the byterange filter.
4326 *) Get exe CGI's working again on Windows.
4329 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
4330 they keep track of whether or not their post config hook has been
4331 called before. Instead of a static variable (which is replaced when
4332 the DSO is loaded a second time), use userdata in the process pool.
4335 Changes with Apache 2.0a9
4337 *) Win32 now requires perl to complete the final install step for users
4338 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
4339 and installs the conf, htdocs and htdocs/manual directories.
4342 *) Make mod_include use a hash table to associate directive tags with
4343 functions. This allows modules to implement their own SSI tags easily.
4344 The idea is simple enough, a module can insert it's own tag and function
4345 combination into a hash table provided by mod_include. While mod_include
4346 parses an SSI file, when it encounters a tag in the file, it does a
4347 hash lookup to find the function that implements that tag, and passes
4348 all of the relevant data to the function. That function is then
4349 responsible for processing the tag and handing the remaining data back
4350 to mod_include for further processing.
4351 [Paul J. Reder <rederpj@raleigh.ibm.com>]
4353 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
4354 fewer parameters: the local and remote socket addresses were removed
4355 from the parameter list because all required information is available
4356 via the APR socket. [Jeff Trawick]
4358 *) Distribution directory structure reorganized to reflect a
4359 normal source distribution with external install targets.
4362 *) The MPMs that need multiple segments of shared memory now create
4363 two apr_shmem_t variables, one for each shared memory allocation.
4364 the problem is that we can't determine how much memory will be required
4365 for shared memory allocations once we try to allocate more than one
4366 variable. The MM code automatically aligns the shared memory allocations,
4367 so we end up needing to pad the amount of shared memory we want based
4368 on how many variables will be allocated out of the shared memory segment.
4369 It is just easier to create a second apr_shmem_t variable, and two
4370 shmem memory blocks.
4373 *) Cleanup the export list a bit. This creates a single unified list of
4374 functions exported by APR. The export list is generated at configure
4375 time, and that list is then used to generate the exports.c file.
4376 Because of the way the export list is generated, we only export those
4377 functions that are valid on the platform we are building on.
4380 *) Enable logging the cookie with mod_log_config
4381 [Sander van Zoest <sander@covalent.net>]
4383 *) Fix a segfault in mod_info when it reaches the end of the configuration.
4386 *) Added lib/aputil/ as a placeholder for utility functions which are not
4387 specific to the Apache HTTP Server (but do not make sense with APR).
4388 The first utility is "apu_dbm": a set of functions to work with DBM
4389 files. This first version can be compiled for SDBM or GDBM databases.
4392 *) Complete re-write of mod_include. This makes mod_include a filter that
4393 uses buckets directly. This has now served the FAQ correctly.
4394 [Paul Reder <rederpj@raleigh.ibm.com>]
4396 *) Allow modules to specify the first filter in a sub_request when
4397 making the sub_request. This keeps modules from having to change the
4398 output_filter immediately after creating the sub-request, and therefore
4399 skip the sub_req_output_filter. [Ryan Bloom]
4401 *) Update ab to accept URLs with IPv6 literal address strings (in the
4402 format described in RFC 2732), and to build Host header fields in
4403 the same format. This allows IPv6 literal address strings to be
4404 used with ab. This support has been tested against Apache 1.3 with
4405 the KAME patch, but Apache 2.0 does not yet work with this format
4406 of the Host header field. [Jeff Trawick]
4408 *) Accomodate an out-of-space condition in the piped logs and the
4409 rotatelogs.c code, and no longer churn log processes for this
4410 condition. [Victor J. Orlikowski]
4412 *) Add support for partial writes with apr_sendfile() to core_output_filter.
4415 Changes with Apache 2.0a8
4417 *) Add a directive to mod_mime so that filters can be associated with
4421 *) Get multi-views working again. We were setting the path_info
4422 field incorrectly if we couldn't find the specified file.
4425 *) Fix 304 processing. The core should never try to send the headers
4426 down the filter stack. Always, just setup the table in the request
4427 record, and let the header filter convert it to data that is ready
4431 *) More fixes for the proxy. There are still bugs in the proxy code,
4432 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
4436 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
4439 *) APR: Add new apr_getopt_long function to handle long options.
4440 [B. W. Fitzpatrick <fitz@red-bean.com>]
4442 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
4443 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
4444 hostname resolution/address string parsing and building
4445 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
4446 of one of the apr_sockaddr_t structures for a socket. Change
4447 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
4449 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
4450 I have proxied pages with it, cleanup will commence soon.
4453 *) Make the proxy work with filters. This isn't perfect, because we
4454 aren't dealing with the headers properly. [Ryan Bloom]
4456 *) Do not send a content-length iff the C-L is 0 and this is a head
4457 request. [Ryan Bloom]
4459 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
4460 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
4462 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
4464 *) Get the default_handler to stop trying to deal with HEAD requests.
4465 The idea is to let the content-length filter compute the C-L before
4466 we try to send the data. If we can get the C-L correctly, then we
4467 should send it in the HEAD response.
4470 *) The Header filter can now determine if a body should be sent based
4471 on r->header_only. The general idea of this is that if we delay
4472 deciding to send the body, then we might be able to compute the
4473 content-length correctly, which will help caching proxies to cache
4474 our data better. Any handler that doesn't want to try to compute
4475 the content-length can just send an EOS bucket without data and
4476 everything will just work.
4479 *) Add the referer to the error log if one is available.
4480 [Markus Gyger <mgyger@itr.ch>]
4482 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
4483 change, the root of the configuration tree has been exposed to modules
4485 [Ryan Morgan <rmorgan@covalent.net>]
4487 *) Get the core_output_filter to use the bucket interface directly.
4488 This keeps us from calling the content-length filter multiple times
4489 for a simple static request.
4492 *) We are sending the content-type correctly now.
4493 [Ryan Bloom and Will Rowe]
4495 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
4496 a bogus bytes-sent value when the only thing being sent was trailers
4497 and writev() returned an error (or EAGAIN). [Jeff Trawick]
4499 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
4500 hints file to determine which platforms define
4501 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
4504 *) APR: add apr_get_home_directory() [Jeff Trawick]
4506 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
4508 *) Not all platforms have INADDR_NONE defined by default. Apache
4509 used to make this check and define INADDR_NONE if appropriate,
4510 but APR needs the check too, and I suspect other applications will
4511 as well. APR now defines APR_INADDR_NONE, which is always a valid
4512 value on all platforms.
4513 [Branko Èibej <brane@xbc.nu>]
4515 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
4516 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
4518 *) Relax the syntax checking of Host: headers in order to support
4519 iDNS. PR#6635 [Tony Finch]
4521 *) When reading from file buckets we convert to an MMAP if it makes
4522 sense. This also simplifies the default handler because the
4523 default handler no longer needs to try to create MMAPs.
4526 *) BUFF has been removed from the main server. The BUFF code will remain
4527 in the code until it has been purged from the proxy module as well.
4530 *) Byteranges have been completely re-written to be a filter. This
4531 has been tested, and I believe it is working correctly, but it could
4532 doesn't work for the Adobe Acrobat plug-in. The output almost matches
4533 the output from 1.3, the only difference being that 1.3 includes
4534 a content-length in the response, and this does not.
4537 *) APR read/write functions and bucket read functions now operate
4538 on unsigned integers, instead of signed ones. It doesn't make
4539 any sense to use signed ints, because we return the error codes,
4540 so if we have an error we should report 0 bytes read or written.
4543 *) Always compute the content length, whether it is sent or not.
4544 The reason for this, is that it allows us to correctly report
4545 the bytes_sent when logging the request. This also simplifies
4546 content-length filter a bit, and fixes the actual byte-reporing
4547 code in mod_log_config.c
4550 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
4551 it says, because it was only used by EOS and FLUSH buckets. Since
4552 neither of those are required at the end of a brigade, this was
4553 really signifying FLUSH_THE_DATA, but that can be determined better
4554 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
4555 buckets now return a length of 0, which is actually the amount of data
4556 read, so they make more sense.
4559 *) Allow the core_output_filter to save some data past the end of a
4560 request. If we get an EOS bucket, we only send the data if it
4561 makes sense to send it. This allows us to pipeline request
4562 responses. As a part of this, we also need to allocate mmap
4563 buckets out of the connection pool, not the request pool. This
4564 allows the mmap to outlive the request.
4567 *) Make blocking and non-blocking bucket reads work correctly for
4568 sockets and pipes. These are the only bucket types that should
4569 have non-blocking reads, because the other bucket types should
4570 ALWAYS be able to return something immediately.
4573 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
4574 server, but use Ctrl+Break to initiate a graceful restart
4575 instead of duplicating behavior. [John Sterling]
4577 *) Patch mod_autoindex to set the Last-Modified header based on
4578 the directory's mtime, and add the ETag header. [William Rowe]
4580 *) Merge the 1.3 patch to add support for logging query string in
4581 such a way that "%m %U%q %H" is the same as "%r".
4584 *) Port three log methods from mod_log_config 1.3 to 2.0:
4585 CLF compliant '-' byte count, method and protocol.
4588 *) Add a new LogFormat directive, %c, that will log connection
4589 status at the end of the response as follows:
4590 'X' - connection aborted before the response completed.
4591 '+' - connection may be kept-alive by the server.
4592 '-' - connection will be closed by the server.
4595 *) Expand APR for WinNT to fully accept and return utf-8 encoded
4596 Unicode file names and paths for Win32, and tag the Content-Type
4597 from mod_autoindex to reflect that charset if the the feature
4598 macro APR_HAS_UNICODE_FS is true. [William Rowe]
4600 *) Compute the content length (and add appropriate header field) for
4601 the response when no content length is available and we can't use
4602 chunked encoding. [Jeff Trawick]
4604 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
4605 so that content input filters get dechunked data when using
4606 the default handler. Also removed REQUEST_CHUNKED_PASS.
4609 *) Add mod_ext_filter as an experimental module. This module allows
4610 the administrator to use external programs as filters. Currently,
4611 only filtering of output is supported. [Jeff Trawick]
4613 *) Most Apache functions work on EBCDIC machines again, as protocol
4614 data is now translated (again). [Jeff Trawick]
4616 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
4617 the EBCDIC support. They are noops on ASCII machines, so this
4618 type of translation doesn't have to be surrounded by #ifdef
4619 CHARSET_EBCDIC. [Jeff Trawick]
4621 *) Fix mod_include. tag commands work again, and the server will
4622 send the FAQ again. This also allows mod_include to set aside
4623 buckets that include partial buckets.
4624 [Ryan Bloom and David Reid]
4626 *) Add suexec support back. [Manoj Kasichainula]
4628 *) Lingering close now uses the socket directly instead of using
4629 BUFF. This has been tested, but since all we can tell is that it
4630 doesn't fail, this needs to be really hacked on.
4633 *) Allow filters to modify headers and have those headers be sent to
4634 the client. The idea is that we have an http_header filter that
4635 actually sends the headers to the network. This removes the need
4636 for the BUFF to send headers.
4639 *) Charset translation: mod_charset_lite handles translation of
4640 request bodies. Get rid of the xlate version of ap_md5_digest()
4641 since we don't compute digests of filtered (e.g., translated)
4642 response bodies this way anymore. (Note that we don't do it at
4643 all at the present; somebody needs to write a filter to do so.)
4646 *) Input filters and ap_get_brigade() now have a input mode parameter
4647 (blocking, non-blocking, peek) instead of a length parameter.
4650 *) Update the mime.types file to the registered media types as
4651 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
4654 *) Namespace protect some macros declared in ap_config.h
4657 *) Support HTTP header line folding with input filtering.
4660 *) Mod_include works again. This should still be re-written, but at
4661 least now we can serve an SHTML page again.
4664 *) Begin to remove BUFF from the core. Currently, we keep a pointer
4665 to both the BUFF and the socket in the conn_rec. Functions that
4666 want to use the BUFF can, functions that want to use the socket,
4667 can. They point to the same place.
4670 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
4671 [Tomas "Ögren" <stric@ing.umu.se>]
4673 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
4674 associated pool goes away. (APR pipes on OS/2 were already had this
4675 logic.) This resolvs a fatal file descriptor leak with CGIs.
4678 *) The final line of the config file was not being read if there was
4679 no \n at the end of it. This was caused by apr_fgets returning
4680 APR_EOF even though we had read valid data. This is solved by
4681 making cfg_getline check the buff that was returned from apr_fgets.
4682 If apr_fgets return APR_EOF, but there was data in the buf, then we
4683 return the buf, otherwise we return NULL.
4686 *) Piped logs work again in the 2.0 series.
4689 *) Restore functionality broken by the mod_rewrite security fix:
4690 rewrite map lookup keys and default values are now expanded
4691 so that the lookup can depend on the requested URI etc.
4692 PR #6671 [Tony Finch]
4694 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
4695 security bug in some mass virtual hosting configurations
4696 that can allow a remote attacker to retrieve some files
4697 on the system that should be inaccessible. [Tony Finch]
4699 *) Add a pool bucket type. This bucket is used for data allocated out
4700 of a pool. If the pool is cleaned before the bucket is destroyed, then
4701 the data is converted to a heap bucket, allowing it to survive the
4705 *) Add a flush bucket. This allows modules to signal that the filters
4706 should all flush whatever data they currently have. There is no way
4707 to actually force them to do this, so if a filter ignores this bucket,
4708 that's life, but at least we can try with this.
4711 *) Add an output filter for sub-requests. This filter just strips the
4712 EOS bucket so that we don't confuse the main request's core output
4713 filter by sending multiple EOS buckets. This change also makes sub
4714 requests start to send EOS buckets when they are finished.
4717 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
4718 makes ap_bucket_destroy a return void, which is okay because it
4719 used to always return APR_SUCCESS, and nobody ever checked its
4720 return value anyway.
4721 [Cliff Woolley <cliffwoolley@yahoo.com>]
4723 *) Remove the index into the bucket-type table from the buckets
4724 structure. This has now been replaced with a pointer to the
4725 bucket_type. Also add some macros to test the bucket-type.
4728 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
4729 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
4730 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
4731 All _VAR_ flavors changes to _DATA to be absolutely clear.
4734 *) Add support for /, //, //servername and //server/sharename
4735 parsing of <Directory> blocks under Win32 and OS2.
4736 [Tim Costello, William Rowe, Brian Harvard]
4738 *) Remove the function pointers from the ap_bucket type. They have been
4739 replaced with a global table. Modules are allowed to register bucket
4740 types and use then use those buckets.
4743 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
4744 once we finish writing the request body to the cgi child process;
4745 otherwise, the client doesn't hit EOF on stdin. Small request bodies
4746 worked without this change (for reasons I don't understand), but large
4747 ones didn't. [Jeff Trawick]
4749 *) Remove file bucket specific information from the ap_bucket type.
4750 This has been moved to a file_bucket specific type that hangs off
4751 the data pointer in the ap_bucket type.
4754 *) Input filtering now has a third argument. This is the amount of data
4755 to read from lower filters. This argument can be -1, 0, or a positive
4756 number. -1 means give me all the data you have, I'll deal with it and
4757 let you know if I need more. 0 means give me one line and one line
4758 only. A positive number means I want no more than this much data.
4760 Currently, only 0 and a positive number are implemented. This allows
4761 us to remove the remaining field from the conn_rec structure, which
4765 *) Big cleanup of the input filtering. The goal is that http_filter
4766 understands two conditions, headers and body. It knows where it is
4767 based on c->remaining. If c->remaining is 0, then we are in headers,
4768 and http_filter returns a line at a time. If it is not 0, then we are
4769 in body, and http_filter returns raw data, but only up to c->remaining
4770 bytes. It can return less, but never more.
4771 [Greg Ames, Ryan Bloom, Jeff Trawick]
4773 *) mod_cgi: Write all of the request body to the child, not just what
4774 the kernel would accept on the first write. [Jeff Trawick]
4776 *) Back out the change that moved the brigade from the core_output_filters
4777 ctx to the conn_rec. Since all requests over a given connection
4778 go through the same core_output_filter, the ctx pointer has the
4782 *) Fix another bug in the send_the_file() read/write loop. A partial
4783 send by apr_send would cause unsent data in the read buffer to
4784 get clobbered. Complete making send_the_file handle partial
4785 writes to the network.
4788 *) Fix a couple of type fixes to allow compilation on AIX again
4789 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
4791 *) Fix bug in send_the_file() which causes offset to be ignored
4792 if there are no headers to send.
4795 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
4796 filter. Useful for supporting Windows 9* with a binary
4797 compiled on Windows NT.
4800 Changes with Apache 2.0a7
4802 *) Reimplement core_output_filter to buffer/save bucket brigades
4803 across multiple calls to the core_filter. The brigade will be
4804 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
4805 thresholds are hit or the EOS bucket is received.
4808 *) Create experimental filter (buffer_filter) that coalesces bytes
4809 into one large buffer before invoking the next filter in the
4810 chain. This filter is particularly useful with the current
4811 implementation of mod_autoindex when it inserted above the
4812 chunk_filter. mod_autoindex generates a lot of brigades that
4813 containing buckets holding just a few bytes each. The
4814 buffer_filter coalesces these buckets into a single large bucket.
4817 *) Add apr_sendfile() support into the core_output_filter.
4820 *) Add apr_sendv() support into the core_output_filter.
4823 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
4824 [Mike Abbott <mja@sgi.com>]
4826 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
4827 make much sense, because Apache uses buckets instead of BUFFs now.
4830 *) send_the_file now falls back to a read/write loop on platforms that
4831 do not have sendfile.
4832 [Ryan Bloom and Brian Havard]
4834 *) Install apachectl correctly, and substitute the proper values so
4835 that it works again. [Ryan Bloom]
4837 *) Better(??) handle platforms that lack sendfile().
4840 *) APR now has UUID generation/formatting/parsing support.
4843 *) Begin the http_filter. This is an input filter that understands
4844 the absolute basic amount required to parse an HTTP Request. The
4845 goal is to be able to split headers from request body before passing
4846 the data back to the other filters.
4849 *) Bring forward from 1.3.13 the config directory implementation
4852 *) install apxs if it is created
4855 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
4856 conversions. [William Rowe]
4858 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
4859 ap_add_output_filter(). [Jeff Trawick]
4861 *) Multiple build and configuration fixes
4864 -add datadir and localstatedir substitutions
4866 -fix logfilename misspelling
4867 -fix evaluation of installation dir variables and
4868 -replace $foobar by $(foobar) to be usefull in the makefile
4872 -add rules for cross-compiling in rules.mk. Okay, rule to check for
4873 $CC_FOR_BUILD is still missing
4874 -use CHECK_TOOL instead of CHECK_PROG for ranlib
4875 -add missing "AR=@AR@" to severaly Makefile.in's
4876 -cache result for "struct rlimit"
4877 -compile all helper programs with native and cross compiler
4878 and use the native version to generate header file
4879 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
4881 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
4883 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
4885 *) Fix a bug where a client which only sends \n to delimit header
4886 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
4887 message. Start working on ebcdic co-existance with input
4889 [William Rowe, Greg Ames]
4891 *) If mod_so is enabled in the server always create libexec, even
4892 if there are no modules installed in this directory. This is a
4893 requirement for APXS to work correctly.
4896 *) Connection oriented output filters are now stored in the
4897 conn_rec instead of the request_rec. This allows us to add the
4898 output filter in the pre-connection phase instead of the
4899 post_read_request phase, which keeps us from trying to write an
4900 error page before we have a filter to write to the network.
4901 [Ryan Bloom, Jeff Trawick, and Greg Ames]
4903 *) Cleaning up an mmap bucket no longer deletes the mmap. An
4904 mmap can be used across multiple buckets (default_handler with
4905 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
4906 the mmap itself can't be associated with the bucket.
4909 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
4912 *) Radical surgery to improve mod_isapi support under Win32.
4913 Includes a number of newer ServerSupportFunction calls, support
4914 for ReadClient (in order to retrieve POSTs greater than 48KB),
4915 and general bug fixes to more reliably load ISAPI .dll's and
4916 prevent leaking handle resources. Note: There are still
4917 discrepancies between IIS's and Apache's ServerVariables, and
4918 async calls are still not supported. Additional warnings are
4919 logged to facilitate debugging of unsupported ISAPI calls.
4922 *) Add input filtering to Apache. The basic idea for the input
4923 filters is the same as the ideas for output filters. The biggest
4924 difference is that instead of calling ap_pass_brigade, ap_get_brigade
4925 should be called, and the order of execution for the filter itself is
4926 different. When writing an output filter, a brigade is passed in,
4927 and filters operate directly on that brigade, when done, they call
4928 ap_pass_brigade. Input filters are the exact opposite. Because input
4929 is not a push operation, filters first call ap_get_brigade. When this
4930 function returns, the input filter will be left with a valid brigade.
4931 The input filter should then operate on the brigade, and return.
4934 *) Fix building on BSD/OS using its native make. The build system
4935 falls back to the BSD .include directive on that host platform.
4938 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
4939 SHA1 and plaintext password encodings. Make feature tests a
4940 bit more flexible. [William Rowe]
4942 *) Charset translation: mod_charset_lite handles output content
4943 translation in a filter. mod_charset_lite no longer ignores
4944 subrequests. A bunch of cruft related to BUFF's support for
4945 translating request and response bodies was removed.
4948 *) Move the addition of the CORE filter to the post_read_request
4949 hook in http_core.c. This removes the need to add the filter in
4950 multiple places and allows for an SSL module to be added much
4951 simpler. [Ryan Bloom]
4953 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
4954 Fix a security problem that affects certain configurations of
4955 mod_rewrite. If the result of a RewriteRule is a filename that
4956 contains expansion specifiers, especially regexp backreferences
4957 $0..$9 and %0..%9, then it may be possible for an attacker to
4958 access any file on the web server. [Tony Finch]
4960 *) Fix a bug where errors that are detected during early request parsing
4961 don't produce visible HTTP error messages at the browser, because
4962 the core_filter wasn't present. [Greg Ames]
4964 *) Provide apr_socklen_t as a portability aid.
4965 [Victor J. Orlikowski]
4967 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
4968 as well as a comment arg to the add, adduser and update cmds.
4969 update allows the user to clear or preserve pw/groups/comment.
4970 Fixed a bug in dbmmanage that prevented the check option from
4971 parsing a password followed by :group... text. Corrected the
4972 seed calcualation for Win32 systems, and added -lsdbm support.
4975 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
4978 *) Avoid a segfault when parsing .htaccess files. An
4979 uninitialized tree pointer was passed to ap_build_config().
4982 *) Change the way that inet_addr & inet_network are checked for
4983 in APR's configure process to allow BeOS BONE to correctly
4984 find them. With this change BeOS BONE now builds from source
4985 with no problems. [David Reid]
4987 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
4988 the end of the parameters to execve() was stored in the wrong
4989 location, overlaying the storage beyond the newargs[] array and
4990 also passing uninitialized storage to execve(), which would
4991 sometimes fail with EFAULT. [Jeff Trawick]
4993 *) Fix a bug parsing configuration file containers. With a sequence
4994 like this in the config file
4996 <IfModule mod_kilroy.c>
4999 <IfModule mod_lovejoy.c>
5004 the second container would be terminated at the blank line due to
5005 sediment in the buffer from reading the prior </IfModule> and an
5006 error message would be generated for the real </IfModule> for the
5007 second container. Also due to this problem, any two characters
5008 could be used for "</" in the close of a container.
5011 *) ap_add_filter prototype changed to remove the ctx pointer. The
5012 pointer still remains in the filter structure, but it can not be
5013 a part of the ap_add_filter prototype. The reason is that when
5014 the core uses AddFilter to add a filter to the stack it doesn't
5015 know how to allocate the ctx pointer, or even how much memory should
5016 be allocated. The filters will have to be responsible for allocating
5017 the ctx memory when they need it.
5020 *) Add an AddFilter directive. This directive takes a list of filters
5021 that should be activated for the requested resource.
5024 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
5025 some other platforms). [Jeff Trawick]
5027 *) Modify mod_include to be a filter. Currently, it has only been tested
5028 on actual files, but it should work for CGI scripts too.
5031 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
5032 writes. apr_flush() for Unix: handle interrupted writes.
5035 *) NameVirtualHost can now take "*" as an argument instead of
5036 an IP address. This allows you to create a purely name-based
5037 virtual hosting server that does not have any IP addresses in
5038 the configuration file and which ignores the local address
5039 of any connections. PR #5595, PR #4455 [Tony Finch]
5041 *) Fix some compile warnings in mod_mmap_static.c
5042 [Mike Abbott <mja@sgi.com>]
5044 *) Fix chunking problem with CGI scripts. The general problem was that
5045 the CGI modules were adding an EOS bucket and then the core added an
5046 EOS bucket. The chunking filter finalizes the chunked response when it
5047 encounters an EOS bucket. Because two EOS buckets were sent, we
5048 finalized the response twice. The fix is to make sure we only send one
5049 EOS, by utilizing a flag in the request_rec.
5052 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
5053 and Win32. Previously, the first read from an apr_file_t set up via
5054 apr_put_os_file() would return a '\0'. [Jeff Trawick]
5056 *) Mod_cgid now creates a single element bucket brigade, with a pipe
5057 bucket, instead of using BUFF's and ap_r*.
5060 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
5061 [Mike Abbott <mja@sgi.com>]
5063 *) Remove ap_bopenf from buff code. This required modifying the file_cache
5064 code to use APR file's directly instead of going through BUFFs.
5067 *) Fix compile break on some platforms for mod_mime_magic.c
5068 [John K. Sterling <sterling@covalent.net>]
5070 *) Fix merging of AddDefaultCharset directive.
5071 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
5073 *) Minor revamp of the rlimit sections of code. We now test
5074 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
5075 is now "available" even if the platform doesn't support
5076 the rlimit family (it's just a noop though). [Jim Jagielski]
5078 *) Migrate the pre-selection of which MPM to use for specific
5079 platforms to hints.m4, which contains (or should contain)
5080 all platform specific "hints". [Jim Jagielski]
5082 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
5085 *) Add tables with non-string/binary values to APR.
5088 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
5091 *) Update PCRE to version 3.2. [Ryan Bloom]
5093 *) Change the way buckets' destroy functions are called so that
5094 they can be more directly used when changing the type of a
5095 bucket in place. [Tony Finch]
5097 *) Add generic support for reference-counting the resources used by
5098 buckets, and alter the HEAP and MMAP buckets to use it. Change
5099 the way buckets are initialised to support changing the type of
5100 buckets in place, and use it when setting aside TRANSIENT buckets.
5101 Change the implementation of TRANSIENT buckets so that it can be
5102 mostly shared with IMMORTAL buckets, which are now implemented.
5105 Changes with Apache 2.0a6
5107 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
5109 *) Add a chunking filter to Apache. This brings us one step closer
5110 to removing BUFF. [Ryan Bloom]
5112 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
5113 added to the stack is the last filter to be called. [Ryan Bloom]
5115 *) Apache 2.0 has been completely documented using Scandoc. The
5116 docs can be generated by running 'make docs'. [Ryan Bloom]
5118 *) Add filtered I/O to Apache. This is based on bucket brigades,
5119 Currently the buckets still use BUFF under the covers, but that
5120 should change quickly. The only currently written filter is the
5121 core filter which just calls ap_bwrite. [The Apache Group]
5123 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
5124 built with thread support. [Jeff Trawick]
5126 *) Abort configuration if --with-layout was specified and there's
5127 no layout definition file. [Ken Coar]
5129 *) Add support for '--with-port=n' option to configure. [Ken Coar]
5131 *) Add support for extension methods for the Allow response header
5132 field, and an API routine for accessing r->allowed and the
5133 list of extension methods in a unified manner. [Ken Coar]
5135 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5136 [Rob Simonson <simo@us.ibm.com>]
5138 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5139 APACHE_XLATE builds. [Jeff Trawick]
5141 *) A configuration file parsing problem was fixed. When the
5142 configuration file started with an IfModule/IfDefine container,
5143 only the last statement in the container would be retained.
5146 Changes with Apache 2.0a5
5148 *) Perchild is serving pages after passing them to different child
5149 processes. There are still a lot of bugs, but this does work. I
5150 have made requests against the same installation of Apache, and had
5151 different servers use different user IDs to serve the responses.
5152 This change moves to using socketpair instead of an AF_UNIX socket.
5155 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5156 It can't seem to pass between child processes yet, but I think we
5157 are closer now than before. This moves us back to using Unix
5158 Domain Sockets. [Ryan Bloom]
5160 *) libapr functions and types renamed with apr_ prefix.
5161 #include "apr_compat.h" for 1.3.x backwards compat
5164 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5165 return the right information on the local socket address.
5166 [Gregory Nicholls <gnicholls@level8.com>]
5168 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5169 [Gregory Nicholls <gnicholls@level8.com>]
5171 *) Add an option to not detach from the controlling terminal without
5172 going into single process mode. This allows for much easier
5173 debugging of the process startup code. [Ryan Bloom]
5175 *) ab: don't use perror() to report the failure of an APR function.
5178 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5179 scoreboard on graceful restarts.
5182 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5183 An invalid ap_proc_t was passed to ap_create_process().
5186 *) Allow modules to register filters. Those filters are still
5187 never called, but this is a step in the right direction.
5188 [Ryan Bloom and Greg Stein]
5190 *) Register the mod_cgid daemon process for cleanup so that it is
5191 killed at termination if it does not die when the parent gets
5192 SIGTERM. This change is to fix occasional problems where the
5193 process stays around. Bugs in similar logic in mod_rewrite and
5194 mod_include were also fixed. [Jeff Trawick]
5196 *) Fix a bug in the time handling. Basically, we were imploding a time
5197 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5198 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5199 uses those two fields to adjust the time value. Because of the HTTP
5200 spec, both of those values can be zero'ed out safely. This fixes
5201 the bug correctly. [Ryan Bloom]
5203 *) Fix a couple of place in the Windows code where the wrong error
5204 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
5206 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5208 *) Added the APR_EOL_STR macro for platform dependent differences in
5209 logfiles and other raw text (such as all APR files). Fixes logfiles
5210 not terminated with cr/lf sequences in Win32. [William Rowe]
5212 *) Move all strings functions in APR to src/lib/apr/strings and create
5213 apr_strings.h for the prototypes. [Ryan Bloom]
5215 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5216 to repeat the syscall until we stop getting EINTR. I noticed a
5217 related problem at termination (SIGTERM) on FreeBSD when using
5218 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5219 implementation work properly with child init. Previously, ap_lock()
5220 was essentially a no-op because all children were using different
5221 locks and thus nobody ever blocked. [Jeff Trawick]
5223 *) The htdocs/ tree has been moved out of the CVS source tree into
5224 a separate area for easier development. This has NO EFFECT on
5225 end-users or Apache installations. [Ken Coar]
5227 *) Integrate the mod_dav module for WebDAV protocol handling. This
5228 adds the dav and dav_fs modules, the SDBM library, and additional
5229 XML handling utilities. [Greg Stein]
5231 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
5234 *) Update the lib/expat-lite/ library (bring forward changes from
5235 the Apache 1.3 repository). [Greg Stein]
5237 *) If sizeof(long long) == sizeof(long), then prefer long in APR
5238 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
5240 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
5241 machines where sendfile is detected, but nobody has written ap_sendfile.
5242 [Dave Hill <ddhill@zk3.dec.com>]
5244 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
5246 *) ab would start up more connections than needed, then quit when the
5247 desired number were finished. Also fixed a logic error involving
5248 ab keepalives. [Victor J. Orlikowski]
5250 *) WinNT: Implement non-blocking pipes with timeouts to communicate
5251 with CGIs. Apache 2.0a4 had non-blocking pipes but without
5252 timeouts (i.e, if a timeout was specified, the pipe reverted to
5253 a full blocking pipe). Now the behaviour is more in line with
5254 Unix non-blocking pipes.
5257 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
5258 cache open file handles along with accept socket reuse enables
5259 Apache 2.0 to serve non-keepalive requests for static files at
5260 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
5261 and Apache 2.0 will serve almost 1200 rps on my system).
5264 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
5265 supports two config directives, mmapfile (same behavious as
5266 mod_mmap_static) and cachefile. Use the cachefile directive
5267 to cache open file handles. This directive only works on systems
5268 that have implemented the ap_sendfile API. cachefile works today
5269 on Windows NT, but has not been tested on any flavors of Unix.
5272 *) Cleanup the configuration. With the last few changes the
5273 configuration process automatically:
5274 inherits information about how to build from APR. Allowing
5275 APR to inform Apache that it should or should not use -ldl
5277 Detects which mod_cgi should be used mod_cgi or mod_cgid,
5278 based on the threading model
5280 Apache calls APR's configure process before finishing it's
5281 configuration processing, allowing for more information flow
5286 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
5287 with non-zero argument makes the socket non-blocking. BeOS and
5288 OS/2 already worked this way. [Jeff Trawick]
5290 *) ap_close() now calls ap_flush() for buffered files, so write
5291 operations work a whole lot better on buffered files.
5294 *) Fix error messages issued from MPMs which explain where to change
5295 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
5298 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
5299 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
5300 now the way that the blocking state of a pipe is manipulated.
5301 ap_block_pipe() is gone. [Jeff Trawick]
5303 *) Correct the problem where the only local host name that the IP stack
5304 can discover are 'undotted' private names. If no fully qualified
5305 domain name can be identified, the default ServerName will be set to
5306 the machine's IP address string. A warning is always provided if the
5307 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
5309 *) Repair problems with config file processing which caused segfault
5310 at init when virtual hosts were defined and which caused ServerName to
5311 be ignored when there was no valid DNS setup. [Jeff Trawick]
5313 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
5315 *) Add ap_sendfile implementation for AIX
5316 [Victor J. Orlikowski]
5318 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
5319 apr_network_io.h, and apr_thread_proc.h.
5320 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
5322 *) Bring the allocation and pool debugging code back into a working
5323 state. This will need to be tested as so far it's only been used on
5326 *) Change configuration command setup to be properly typesafe when in
5327 maintainer mode. Note that this requires a compiler that can initialise
5328 unions. [Ben Laurie]
5330 *) Turn on buffering for config file reads. Part of this was to
5331 repair buffered I/O support in Unix and implement buffered
5332 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
5334 *) Win32: Fix problem where UTC offset was not being set correctly
5335 in the access log. Problem reported on news group by Jerry Baker.
5338 *) Fix segfault when reporting this type of syntax error:
5339 "</container> without matching <container> section", where
5340 container is VirtualHost or Directory or whatever.
5343 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
5344 Prevent the source code for CGIs from being revealed when
5345 using mod_vhost_alias and the CGI directory is under the document root
5346 and a user makes a request like http://www.example.com//cgi-bin/cgi
5347 as reported in <news:960999105.344321@ernani.logica.co.uk>
5350 *) Add support for the new Beos NetwOrking Environment (BONE)
5353 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
5354 final input char is incomplete; ap_bwrite_xlate() now handles
5355 incomplete final input chars. [Jeff Trawick]
5357 *) Yet another update to saferead/halfduplex stuff -- need to ensure
5358 that a bhalfduplex call occurs before logging or else DNS and
5359 such can delay the last packet of the response. [Dean Gaudet]
5361 *) Some syscall reduction in APR on unix -- don't seek when setting
5362 up an mmap; and don't fcntl() more than once per socket.
5365 *) When mod_cgid is started as root, the cgi daemon now switches
5366 to the configured User/Group (like other httpd processes)
5367 instead of continuing as root. [Jeff Trawick]
5369 *) The prefork MPM now uses an APR lock for the accept() mutex.
5370 It has not been getting a lock at all recently. httpd -V now
5371 displays APR's selection of the lock mechanism instead of the
5372 symbols previously respected by prefork. [Jeff Trawick]
5374 *) Change the mmap() feature test to check only for existence.
5375 The previous check required features not used by Apache.
5378 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
5379 sometimes mangled. The len parm to accept() was not
5380 initialized, leading sometimes to an endless loop of failed
5381 accept() calls on OS/390 and anywhere else that failed the call
5382 if the len was negative. Use <sys/un.h> for struct sockaddr_un
5383 instead of declaring it ourselves to fix a compilation problem
5384 on Solaris. [Jeff Trawick]
5386 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
5388 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
5390 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
5392 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
5393 initialization if ALLOC_DEBUG is defined; no known symptom
5394 otherwise. [Jeff Trawick]
5396 *) Fix typo in configure script when checking for mod_so. bash
5397 doesn't seem to have a problem but /bin/sh on Solaris does.
5398 Symptom: "./configure: test: unknown operator =="
5401 *) Rebind the Win32 NT and 9x services control into the MPM.
5402 All console, WinNT SCM and Win9x pseudo-service control code is
5403 now wrapped within the WinNT MPM.
5406 *) Make a copy of getenv("PATH") before storing for later use. Some
5407 getenv() implementations use the same storage for successive calls.
5408 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
5410 *) Server Tokens work in 2.0 again. This also propogates the change
5411 to allow just the product name in the server string using
5415 Changes with Apache 2.0a4
5417 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
5418 won't need to call it. [Greg Ames, Jeff Trawick]
5420 *) Move pre_config hook call to between configuration read and config
5421 tree walk. This allows all modules to implement pre_config hooks
5422 and know that they will be called at an appropriate time.
5425 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
5428 *) Add pre-config hooks back to all modules.
5431 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
5432 ContentDigest enabled and we can't/don't mmap the file.
5435 *) We now report the correct line number for syntax errors in config
5436 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
5438 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
5439 related bugs, and changed shmem/locking to use apr API. Shared-mem
5440 is currently disabled, however, because of problems with graceful
5441 restarts. [Ronald Tschalär]
5443 *) Fix corruption of IFS variable in --with-module= handling.
5444 Depending on the user's shell or customization thereof, there
5445 would be errors generating ap_config_auto.h later in the configure
5446 procedure. [Jeff Trawick]
5448 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
5449 isn't used (as in 1.3), except that on Unix it is now logged via
5450 ap_log_rerror() instead of by the child having STDERR_FILENO refer
5451 to the error log. [Greg Ames, Jeff Trawick]
5453 *) Add '-D' argument processing for run time configuration defines.
5456 *) Organize http_main.c as independent code, such that no code or
5457 global data is exported from it. WIN32 will dynamically link it
5458 to the server core, so this will prevent mutual dependency.
5461 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
5462 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
5465 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
5466 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
5468 *) Add mod_charset_lite for configuring character set translation.
5471 *) Add '-n' option to htpasswd to make it print its user:pw record
5472 on stdout rather than having to frob a text file. [Ken Coar]
5474 *) Fix saferead. Basically, we flush the output buffer if a read on the
5478 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
5479 a conversion is single-byte only. [Jeff Trawick]
5481 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
5482 the BeOS 5.0 documentation says that shutdown doesn't work yet.
5485 *) Fix some minor errors where pid was being manipulated as an int
5486 instead of the portable pid_t. [Roy Fielding]
5488 *) Fix some error log prints that were printing the pointer to a
5489 structure rather than the pid within the structure.
5490 [Jeff Trawick, Roy Fielding]
5492 *) ab: Fix a command-line processing bug; track bad headers in
5493 err_response; support reading headers up to 2K.
5494 [Ask Bjoern Hansen <ask@valueclick.com>]
5496 *) Fix ap_resolve_env() so that it handles new function added in a prior
5497 alpha (see "Added the capability to do ${ENVVAR} constructs in the
5498 config file.") as well as the constructs used by mod_rewrite.
5499 [Paul Reder <rederpj@raleigh.ibm.com>]
5501 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
5503 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
5504 APR to perform translation, instead of accessing the hard-coded tables
5505 in 1.3's ebcdic.c. [Jeff Trawick]
5507 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
5510 *) Add the ability to hook into the config file reading phase. Basically
5511 if a directive is specified EXEC_ON_READ, then when that directive is
5512 read from the config file, the assocaited function is executed. This
5513 should only be used for those directives that must muck with HOW the
5514 server INTERPRETS the config. This should not be used for directives
5515 that re-order or replace items in the config tree. Those changes should
5516 be made in the pre-config step.
5519 *) Add mod_example to the build system.
5522 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
5523 byte character sets. [Jeff Trawick]
5525 *) Pick up various EBCDIC fixes from 1.3 (from Martin
5526 Kraemer and Oliver Reh originally according to the change log).
5529 *) Fix a couple of problems in RFC1413 support (controlled by the
5530 IdentityCheck directive). Apache did not build the request string
5531 properly and more importantly Apache would loop forever if the
5532 would-be ident server dropped the connection before sending a
5533 properly terminated response. [Jeff Trawick]
5535 *) apxs works in 2.0.
5538 *) Reliable piped logs work in 2.0.
5541 *) Introduce a hash table implementation into APR to be used for
5542 replacing tables and other random data structures in Apache.
5545 *) Add some more error reporting to htpasswd in the case of problems
5546 generating or accessing the temporary file. Also, pass in a
5547 buffer if the implementation knows how to use it (i.e., if L_tmpnam
5548 is defined). [Ken Coar]
5550 *) Configure creates config.nice now containing your configure
5551 options. Syntax: ./config.nice [--more-options]
5554 *) Fix various return code problems in APR on Win32. For most of
5555 these, APR was returning APR_EEXIST instead of GetLastError()/
5556 WSAGetLastError(). [Jeff Trawick]
5558 *) Make piped logs work again in version 2.0
5561 *) Add VPATH support to UNIX build system of Apache and APR.
5564 *) Fix ap_tokenize_to_argv to respect the const arguments that are
5568 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
5569 Patch submitted to author.
5572 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
5573 /sbin in PATH on FreeBSD (all submitted to rse previously)
5576 *) Fix building Pthread-based MPMs on OpenBSD
5577 [Sascha Schumann] PR#26
5579 *) Fix ap_readdir() problem on systems where d_name[] field in
5580 struct dirent is declared with only one byte. (This problem only
5581 affected multithreaded builds.) This caused a segfault during
5582 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
5583 least). [Jeff Trawick]
5585 *) Fix some make-portability problems on at least Tru64, Irix
5587 [Sascha Schumann] PR#18, PR#39
5589 *) Add ap_sigwait() to support old-style sigwait() on systems
5590 like OS/390 and UnixWare.
5593 *) Add POSIX-thread flags for more platforms.
5596 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
5597 (on Unix, at least) to handle resolver errors. Fix a bug in
5598 the definition of APR_ENOMEM so that ap_strerror() can spit
5599 out the correct error message for it.
5602 Changes with Apache 2.0a3
5604 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
5607 *) API: *HOOK* macros now have an AP_ prefix
5610 *) Win32: Eliminate redundant calls to initialize winsock.
5611 [Tim Costello <timcostello@ozemail.com.au>]
5613 *) Fix bugs initializing ungetchar for pipes.
5614 [Chia-liang Kao <clkao@CirX.ORG>]
5616 *) The ab program in the src/support directory is now portable using
5620 *) Support directory is being compiled when the server is built
5623 *) The configure option --with-program-name has been added to allow
5624 developers to rename the executable at configure time. This also
5625 changes the name of the config files to match the executable's name.
5628 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
5629 containing version numbers. [Martin Pool]
5631 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
5632 Unix; access_log and error_log now created with these perms; non-
5633 Unix is unaffected [Jeff Trawick]
5635 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
5636 Replaced more magic numbers with MD5_DIGESTSIZE.
5637 [William Rowe, Roy Fielding]
5639 *) Win32: Get mod_auth_digest compiling and added to the Windows
5640 build environment. Not tested and I'd be suprised if it
5641 actually works. [Bill Stoddard]
5643 *) Revamp the Win32 make environment. Makefiles have been removed and
5644 Apache.dsw created to bring together all the pieces. Create new file
5645 os/win32/BaseAddr.ref to define module base addresses (to prevent
5646 dll relocation at start-up).
5647 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
5649 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
5650 of the \015, \012, and \015\012 constants with macros.
5653 *) Add ap_xlate_open() et al for translation of text between different
5654 character sets. The initial implementation requires iconv().
5657 *) More FAQs and answers from comp.infosystems.www.servers.unix.
5658 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5660 *) CGI output is being timed out now.
5663 *) Fix the problem with dieing quietly. dupfile now takes a pool which
5664 is used by the new apr file. There is no reason to create a new file
5665 with the same lifetime as the original file.
5668 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
5669 module base addresses. This will help shooting seg faults
5670 in the field. [William Rowe <wrowe@lnd.com>]
5672 *) Update Apache on Windows documentation. Add new document
5673 describing how to compile Apache on Windows.
5674 [William Rowe <wrowe@lnd.com>]
5676 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
5677 microseconds instead of seconds. Some storage leaks and other
5678 minor bugs in related code were fixed. [Jeff Trawick]
5680 *) Win32: First cut at getting mod_isapi working under 2.0
5681 [William Rowe <wrowe@lnd.com>]
5683 *) First stab at getting mod_auth_digest working under 2.0
5684 quick change summary:
5685 - moved the random byte generation (ap_generate_random_bytes) into APR
5686 - now uses ap_time_t
5687 - compiles and runs on linux
5689 [Brian Martin <bmartin@penguincomputing.com>]
5691 *) Win32: Move the space stripping of physical service names
5692 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
5693 unresolved symbol. Add dependency checking to the
5694 CreateService call to ensure TCPIP and AFP (winsock) is started
5696 [William Rowe <wrowe@lnd.com>]
5698 *) Win32: Add code to perform latebinding on functions that may
5699 not exist on all levels of Windows where Apache runs. This
5700 is needed to allow Apache to start-up on Win95/98. All calls
5701 to non portable functions should be protected with
5702 ap_oslevel checks to prevent runtime segfaults.
5703 [William Rowe <wrowe@lnd.com>]
5705 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
5707 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
5709 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
5710 This addresses PR 1623. Still need to address timing out runaway
5711 CGI scripts. [Bill Stoddard]
5713 *) Win32: Make ap_stat Windows 95/98 friendly
5714 [William Rowe <wrowe@lnd.com>]
5716 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
5717 always fail. Need to initialise the dwOSVersionInfoSize member of the
5718 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
5721 The patch also enhances ap_get_oslevel (and the associated enum) to
5722 handle selected service packs for NT4, and adds recognition for
5723 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
5724 we can use ReadFileScatter and WriteFileGather in readwrite.c.
5725 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
5727 *) Get mod_rewrite building and running, and mod_status building for Win NT
5728 [Allan Edwards <ake@raleigh.ibm.com>]
5730 *) Patch to port mod_auth_db to the 2.0 api and also to support
5731 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
5732 2.7.7. It should work with version 1 as well but I haven't tested it.
5733 [Brian Martin <bmartin@penguincomputing.com>]
5735 *) Get APR DSO code working under Windows. Includes cross platform
5737 [Tim.Costello@BTFinancialgroup.com]
5739 *) Fix some of the Windows APR time functions.
5742 *) FAQ changes related to tidying up historical documents on the web site.
5743 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5745 *) Move Windows DSO code into APR.
5748 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
5749 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
5750 at build time. At this point, the server will not compile on Windows because
5751 of the recent DSO commits. Fixing those next.
5752 [Bill Rowe & Bill Stoddard]
5754 *) Added error checking for file I/O APR routines.
5755 [Jon Travis <jtravis@covalent.net>]
5757 *) APR: Don't use the values of resolver error codes for the
5758 corresponding APR error codes. On Unix and Win32, return the
5759 proper APR error code after a resolver error. [Jeff Trawick]
5761 Changes with Apache 2.0a2
5763 *) Renamed the executable back to httpd on all platforms other
5767 *) Allow BeOS to survive restarts, log properly and a few
5768 small things it had problems with due to the way it setup
5769 users and groups. [David Reid]
5771 *) Get mod_rewrite working with APR locks
5772 [Paul Reder <rederpj@raleigh.ibm.com>]
5774 *) Actually remove the sempahore when the lock cleanup routine
5775 is called on BeOS. [David Reid]
5777 *) Clear hook registrations between reads of the config file.
5778 When DSOs are unloaded and re-loaded the old hook pointers may
5779 no longer be valid. This fix eliminates potential segfaults.
5780 [Allan Edwards <ake@raleigh.ibm.com>]
5782 *) Fix a problem with Sigfunc not being defined or bypassed
5783 if sigaction() wasn't found. [Jim Jagielski]
5785 *) Fix the locking mechanism on BSD variants. They now use fcntl
5786 locks. This allows the server to start and serve pages.
5789 *) First cut at getting the Win32 installer to work
5790 [William Rowe <wrowe@lnd.com>]
5792 *) Get htpasswd compiling under Windows
5793 [William Rowe <wrowe@lnd.com>]
5795 *) Change the log message for a bind() failure to show the
5796 interface and port number. [Jeff Trawick]
5798 *) Import the documentation from 1.3.12 and bring parts of it
5799 up-to-date with respect to the changes that have occurred
5803 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
5804 now logged correctly on BeOS.
5807 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
5808 Makefile.win includes the same user interface as the old
5810 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
5812 *) Win32 exec now uses COMSPEC environment string for command
5813 shell path resolution.
5814 [William Rowe <wrowe@lnd.com>] PR#3715
5816 *) Win32: ap_connect() was not returning correct error condition
5818 [Allen Prescott <allen@clanprescott.com>]
5820 *) Win32: ap_open() was broken on Win9x because an NT-specific
5821 flag was passed to CreateFile. ap_puts() added an unnecessary
5823 [Jeff Trawick <trawick@us.ibm.com>]
5825 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
5826 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
5827 confusing ee/et name and made all extensions language/dialect
5828 rather than country reflecting. Changed example files to
5829 explicit reflect the ISO charset and added a few common
5830 ones to the example config [dirkx]
5832 *) Extend external module capability. To use this, you call
5833 configure with --with-module=path/to/mod1,path/to/mod2,etc.
5836 *) Backported the various "default charset" fixes from 1.3.12,
5837 including the AddDefaultCharset directive. [Jim Jagielski]
5839 *) Added the capability to do ${ENVVAR} constructs in the
5840 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
5841 it does this on a line by line basis; i.e. if the envvar
5842 expands to something with spaces you have to protect it
5843 by adding quotes around it (Unless of course you expect it
5844 to contains more than one argument. Alternatively you
5845 can compile it on a per token basis; which is what people
5846 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
5847 hampers fancier hacks.
5848 [Dirk-Willem van Gulik]
5850 *) Changed the 'ErrorDocument' syntax in that it NO longer
5851 supports the asymetric
5853 ErrorDocument 301 "Some message
5855 Note the opening " quote, without a closing quote. It now
5856 has either the following syntaxes
5858 ErrorDocument XXX /local/uri
5859 ErrorDocument XXX http://valid/url
5860 ErrorDocument XXX "Some Message"
5862 The recognition heuristic is: if it has a space it
5863 is a message. If it has no spaces and starts with a /
5864 or is a valid URL then treat it that way. Otherwise it
5865 is assumed to be a message.
5867 This breaks backward compatibility but makes live a hell
5868 of a lot easier for GUI's and config file parsers.
5869 [Dirk-Willem van Gulik]
5871 *) Changed 'CacheNegotiatedDocs' from its present/not-present
5872 syntax into a 'on' or 'off' syntax. As it currently is the
5873 only non nesting token which uses NO_ARGS and thus is an
5874 absolute pain for any config interface automation. This
5875 breaks backward compatibility. [Dirk-Willem van Gulik]
5877 *) Add ability to add external modules to the build process. This is
5878 done with --with-module=/path/to/module. Modules can only be added
5879 as static modules at this point.
5882 Changes with Apache 2.0a1
5884 *) Fix FreeBSD 3.3 core dump.
5885 Basically, ap_initialize() needs to get called before
5886 create_process(), since create_process() passes op_on structure
5887 to semop() to get a lock, but op_on isn't initialized until
5888 ap_initialize() calls setup_lock(). Here is a slight
5889 rearrangement to main() which calls ap_initialize() earlier...
5890 [Jeff Trawick <trawick@us.ibm.com>]
5892 *) Enable Apache to use sendfile/TransmitFile API
5893 [Bill Stoddard, David Reid, Paul Reder]
5895 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
5899 *) Make file I/O and network I/O writev/sendv APIs consistent.
5900 Eliminate use of ap_iovec_t and use Posix struct iovec.
5901 Use seperate variable on ap_writev to set the number of iovecs
5902 passed in and number of bytes written.
5905 *) Adapt file iol to use APR functions. Replaced ap_open_file()
5906 with ap_create_file_iol(). ap_create_file_iol() requires that
5907 the file be opened prior to the call using ap_open().
5910 *) Port mod_include and mod_cgi to 2.0
5911 [Paul Reder, Bill Stoddard]
5913 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
5914 bytes_read/bytes_written is always valid (never -1). Plus
5915 some fixes to buff.c to correct problems introduced by the
5916 errno => ap_status_t changes a while back. Plus a fix to
5917 chunked encoding introduced right at the beginning of 2.0.
5920 *) Revamped UNIX build system to use autoconf and libtool.
5921 [Manoj Kasichainula, Sascha Schumann]
5923 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
5925 *) SECURITY: More rigorous checking of Host: headers to fix security
5926 problems with mass name-based virtual hosting (whether using mod_rewrite
5927 or mod_vhost_alias).
5928 [Ben Hyde, Tony Finch]
5930 *) Add back support for UseCanonicalName in <Directory> containers.
5931 [Manoj Kasichainula]
5933 *) Added APLOG_STARTUP log type. This allows us to write an error
5934 message without any of the date and time information. As a part
5935 of this change, I also removed all of the calls to fprintf(stderr
5936 and replaced them with calls to ap_log_error using APLOG_STARTUP
5937 writing to stderr is no longer portable, because we don't direct
5938 stderr to the error log on all platforms.
5941 *) Convert error logging functions to take errno as an argument.
5942 This makes our error logs more portable, because some Windows API's
5943 don't set errno. This change allows us to still output a valid
5944 message on all of our platforms.
5947 *) mod_mime_magic runs in 2.0-dev now.
5948 [Paul Reder <rederpj@raleigh.ibm.com>]
5950 *) sendfile has been added to APR.
5951 [John Zedlewski <zedlwski@Princeton.EDU>]
5953 *) buff.c has been converted to no longer use errno.
5954 [Manoj Kasichainula]
5956 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
5957 interface adaption to APR functions did it. [Martin Kraemer]
5959 *) Support DSOs properly on 32-bit HP-UX 11.0
5960 [Dilip Khandekar <dilip@cup.hp.com>]
5962 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
5963 [Ralf S. Engelschall]
5965 *) Cleaned APR build environment integration and bootstrap APR
5966 automatically for developers from src/Configure.
5967 [Ralf S. Engelschall]
5969 *) Fixed building of src/support/htpasswd.c
5970 [Ralf S. Engelschall]
5972 *) When generating the Location: header, mod_speling forgot
5973 to escape the spelling-fixed uri. (Forw-Port from 1.3)
5976 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
5978 *) Change all pools to APR contexts. This is the first step to
5979 incorporating APR into Apache. [Ryan Bloom]
5981 *) Move "handler not found" warning message to below the check
5982 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
5983 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
5985 *) Support line-continuation feature in config.option file and
5986 allow the loading of multiple option sections at once via
5987 ``--with-option=<section1>,<section2>,...''
5988 [Ralf S. Engelschall]
5990 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
5992 Changes with Apache MPM
5994 *) Use asynchronous AcceptEx() and a completion port to accept and
5995 dispatch connections to threads in Windows NT/2000.
5998 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
6001 *) Implement the APACI --with-option facility
6002 (per default used the config.option file).
6003 [Ralf S. Engelschall]
6005 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
6007 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
6008 Replace pre_connection module call with a register_hook call and
6009 implement pre_connection as a hook. The intent is that these hooks will
6010 be extended to allow Apache to be multi-protocol, and also to allow the
6011 calling order to be specified on a per-hook/per-module basis.
6014 *) Implement mpm_* methods as "modules". Each method gets its own
6015 subdir in src/modules (eg: src/modules/prefork). Selection
6016 of method uses Rule MPM_METHOD. [Jim Jagielski]
6018 *) Port the hybrid server from the apache-apr repository as
6019 mpm_mpmt_pthread. [Manoj Kasichainula]
6021 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
6022 amongst the unix MPMs.
6024 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
6025 signal handling for the new world order. [Dean Gaudet]
6027 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
6028 of alloc.c for now. [Dean Gaudet]
6030 *) Handle partial large writes correctly. [Ben Laurie]
6032 *) Eliminate conn_rec's pointer to server. All it knows is the base server
6033 based on IP/port. [Ben Laurie]
6035 *) Port a bunch of modules to the new module structure.
6036 ["Michael H. Voase" <mvoase@midcoast.com.au>]
6038 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
6040 *) Basic restructuring to introduce the MPM concept; includes various
6041 changes to the module API... better described by
6042 docs/initial_blurb.txt. [Dean Gaudet]
6044 Changes with Apache pthreads
6046 *) New buff option added: BO_TIMEOUT. It describes the timeout for
6047 buff operations (generally over a network).
6048 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
6050 *) Created http_accept abstraction. Added 4 new functions (not exported):
6051 init_accept(), begin_accepting_requests(), get_request(),
6052 stop_accepting_requests() [Bill Stoddard]
6054 *) Fix to ap_rprintf call that allows mod_info to work properly.
6055 [James Morris <jmorris@intercode.com.au>]
6057 *) user and ap_auth_type fields were moved from connection_rec to
6058 request_rec. [Ryan Bloom]
6060 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
6061 needed in a threaded server.
6063 *) Initial pthread implementation from from Dean's apache-nspr code.
6064 [Bill Stoddard, Ryan Bloom]
6067 Changes with Apache 1.3.9
6069 *) Remove bogus error message when a redirect doesn't set Location.
6070 Instead, use an empty string to avoid coredump if the error message
6071 was supposed to include a location. [Roy Fielding]
6073 *) Don't allow configure to include mod_auth_digest unless it is
6074 explicitly requested, even if the user asked for all modules.
6077 *) Translate module names to dll names for OS/2 so that they are no more
6078 than 8 characters long and have an extension of "dll" instead of "so".
6081 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
6082 Fix test-compile check to check for randbyte instead of trand32.
6083 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
6084 and tweak to make Amaya happier. [Ronald Tschalär]
6086 *) Ensure that the installed expat include files are world readable,
6087 just like the other header files. [Martin Kraemer]
6089 *) Fixed generated AddModule adjustments in APACI's `configure' script
6090 in order to allow (new) modules like mod_vhost_alias to be handled
6091 correctly (which was touched by the adjustments for mod_alias).
6092 [Ralf S. Engelschall]
6094 *) For binary builds, add -R flag to apachectl to work around the lack of
6095 an absolute path to the ./libexec directory where the libhttp.ep file
6096 is needed for SHARED_CORE architectures. [Randy Terbush]
6098 *) WIN32: Create the CGI script process as DETACHED. This may solve the
6099 problem observed by some Win95/98 users where they get CGI script
6100 output sent to the console. [Bill Stoddard]
6102 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
6103 routines are now called ap_base64* and are 'plain' (i.e., no
6104 pool access or anything clever). Inside util.c the routines acting
6105 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
6106 The oddly named ap_uuencode(), ap_uudecode() are kept around for
6107 now but deprecated. [dirkx]
6109 *) Clean up the base64 and SHA1 additions and make sure they are
6110 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
6111 files. [Roy Fielding]
6113 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
6114 checking. Allow compiling on VS 6.0. [Randy Terbush]
6116 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
6118 *) Use TestCompile to search for the truerand library (rather than blindly
6119 assuming its existence). If it is not found, complain (but do not
6120 exit - yet). [Martin Kraemer]
6122 *) We forgot to add the new exported function names to
6123 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
6125 *) Add description of -T command-line option to usage().
6126 [Ralf S. Engelschall]
6128 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
6129 searched only AFTER libap has been searched, because libap needs
6130 some symbols from libos. [Martin Kraemer]
6132 *) Fix conflict with original mod_digest related to the symbol of the
6133 module dispatch list (which has to be unique for DSO and follow the
6134 usual conventions for the installation procedure).
6135 [Ralf S. Engelschall]
6137 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6138 for other platforms as well. [Martin Kraemer]
6140 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6141 types by AP_LONG and replace reference to renamed variable 'ubuf'
6142 by 'buffer'. [Martin Kraemer]
6144 Changes with Apache 1.3.8 [not released]
6146 *) Flush the output buffer immediately after sending an error or redirect
6147 response, since the result may be needed by the client to abort a
6148 long data transfer or restart a series of pipelined requests.
6149 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
6151 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6152 [Ian Turner <iant@sequent.com>] PR#4735
6154 *) Local struct mmap in http_core.c conflicted with system structure
6155 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6157 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6158 [Ronald Tschalär <ronald@innovation.ch>]
6160 *) Fix a memory leak where the module counts were getting messed
6161 up across restarts. [David Harris <dharris@drh.net>]
6163 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6164 properly in mod_access.
6165 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
6167 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6168 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
6170 *) PORT: Support for compaq/tandem/com.
6171 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
6173 *) Added SHA1 password encryption support to easy migration from
6174 Netscape servers. See support/SHA1 for more information.
6175 Caused the separation of ap_md5.c into md5, sha1 and a general
6176 ap_checkpass.c with just a validate_passwd routine. Added a
6177 couple of flags to support/htpasswd. Some reuse of the to64()
6178 function; hence renamed to ap_to64().
6179 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
6181 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6182 with ASCII/EBCDIC conversions in "ident" query.
6183 [David McCreedy <McCreedy@us.ibm.com>]
6185 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6186 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6187 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6189 *) Fix SIGSEGV on some systems because the Vary fix below included
6190 a call to table_do with a variable argument list that was not
6191 NULL terminated. Replaced with better implementation. [Roy Fielding]
6193 Changes with Apache 1.3.7 [not released]
6195 *) The "Vary" response header field is now sanitised right before
6196 the header is sent back to the client. Multiple "Vary" fields
6197 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6198 "Vary: host, negotiate, host, accept-language") are reduced to
6199 single instances. This is a better solution than the force-no-vary
6200 one (which is still valid for clients that can't cope with Vary
6201 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6203 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
6205 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6206 least on Linux and FreeBSD for now.
6209 *) Win32: More apache -k restart work. Restarts are now honored
6210 immediately and connections in the listen queue are -not- lost.
6211 This is made possible by the use of the WSADuplicateSocket()
6212 call. The listeners are opened in the parent, duplicated, then
6213 the duplicates are passed to the child. The original listen sockets
6214 are not closed by the parent across a restart, thus the listen queue
6216 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6218 *) Fix handling of case when a client has sent "Expect: 100-continue"
6219 and we are going to respond with an error, but get stuck waiting to
6220 discard the body in the pointless hope of preserving the connection.
6221 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
6223 *) Fix 'configure' to work correctly with SysV-based versions of
6224 'tr' (consistent with Configure's use as well). [Jim Jagielski]
6226 *) apxs: Add "-S var=val" option which allows for override of CFG_*
6227 built-in values. Add "-e" option which works like -i but doesn't
6228 install the DSO; useful for editing httpd.conf with apxs. Fix
6229 editing code so that multiple invocations of apxs -a will not
6230 create duplicate LoadModule/AddModule entries; apxs can now be
6231 used to re- enable/disable a module. [Wilfredo Sanchez]
6233 *) Win32: Update the server to use Winsock 2. Specifically, link with
6234 ws2_32.lib rather than wsock32.lib. This gives us access to
6235 WSADuplcateSocket() in addition to some other enhanced comm APIs.
6236 Win 95 users may need to update their TCP/IP stack to pick up
6237 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
6238 [Bill Stoddard stoddard@raleigh.ibm.com]
6240 *) Win32: Redirect CGI script stderr (script debug info) into the
6241 error.log when CGI scripts fail. This makes Apache on Win32
6242 behave more like Unix.

6262 command potentially _is_ GCC. [Ralf S. Engelschall]
6264 *) Fix apxs build issues on AIX
6265 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
6267 *) DocumentRoot Checking: Under previous versions, when Apache
6268 first started up, it used to do a stat of each DocumentRoot to
6269 see if it existed and was a directory. If not, then an error
6270 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
6271 does not exist, you will get error messages in error_log. If
6272 the '-t' command line option is used (to check the configuration)
6273 the check of DocumentRoot IS performed. An additional command
6274 line option, '-T', has been added if you want to avoid the
6275 DocumentRoot check even when checking the configuration.
6278 *) Win32: The query switch "apache -S" didn't exit after showing the
6279 vhost settings. That was inconsistent with the other query functions.
6280 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
6282 *) Win32: Changed behaviour of apache -k restart.
6283 Previously, the server would drain all connections in the stack's
6284 listen queue before honoring the restart. On a busy server, this
6285 could take hours. Now, a restart is honored almost immediately.
6286 All connections in Apache's queues are handled but connections in
6287 the stack's listen queue are discarded. Restart triggered by
6288 MaxRequestPerChild is unchanged.
6289 [Bill Stoddard <stoddard@raleigh.ibm.com>]

6319 *) TestCompile updated. We can now run programs and output the
6320 results during the Configure process. [ Jim Jagielski]
6322 *) The source is now quad (long long) aware as needed. Specifically,
6323 the Configure process determines the correct size of off_t and
6324 *void. When the OS/platform/compiler supports quads, ap_snprintf()
6325 provides for the 'q' format qualifier (if quads are not available,
6326 'q' is silently "demoted" to long). [Jim Jagielski]
6328 *) When the username or password fed to htpasswd is too long, include the
6329 size limit in the error message. Also report illegal characters
6330 (currently only ':') in the username. Add the size restrictions
6331 to the man page. [Ken Coar]

6344 if Location isn't set. [Doug MacEachern, Ken Coar]
6346 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
6347 of the Expat 1.0.2 distribution. [Greg Stein]
6349 *) Replace regexec() calls with calls to a new API stub function
6350 ap_regexec(). This solves problems with DSO modules which use the regex
6351 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]

6427 *) Add functionality to the install-bindist.sh script created by
6428 binbuild.sh to use tar when copying distribution files to the

6432 install-bindist.sh now detects the local perl5 path to install
6433 apxs and dbmmanage with proper path to perl interpreter.
6435 Add an install-binsupport target which copies the source files

6610 This allows for special configurations like
6611 <Directory proxy:ftp://some.host>
6612 DefaultType gargle/blurb
6614 Additionally, add the Content-Encoding: header to FTP proxy replies
6615 when the encoding is defined (by the AddEncoding directive).
6616 Because it was missing, it was almost impossible to browse compressed
6617 files using the FTP proxy (works now perfectly in Communicator).
6618 The ftp proxy now also returns the Date: and Server: header lines (if not

6743 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
6744 correctly check for output errors and mark the connection as aborted.
6745 Replaced many direct (unchecked) calls to ap_b* routines with the
6746 analogous ap_r* calls. [Roy Fielding]
6748 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
6749 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
6750 Furthermore map lookups for non-existent keys are now cached as well.
6751 Additionally "txt" maps are now parsed with simple string functions
6752 instead of using ap_pregcomp(). As a side effect a bug that prevented
6753 the usage of keys containing the "," character was fixed.
6754 The changes drastically improve the performance when large rewrite maps
6756 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
6758 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
6759 other than GET, and const'd the definition of method in request_rec.
6762 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
6764 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
6765 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
6767 *) Add %V to mod_log_config, this logs the hostname according to the
6768 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
6769 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
6771 *) Add support for \n and \t to mod_log_config, can be used to produce
6772 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
6774 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
6776 *) Added informative error messages for failed munmap() and fseek() calls
6777 in http_core.c. [John Bley, Roy Fielding]
6779 *) Added some informative error messages for some failed malloc()
6780 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
6782 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
6783 is removed. This allows <Directory proxy:*> directives to work and
6784 prevents invalid requests from killing the process.
6785 [Brian Havard <brianh@kheldar.apana.org.au>]
6787 *) Reorganised FAQ document.
6788 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
6790 *) src/support/: The ApacheBench benchmark program was overhauled by
6791 David N. Welton: you can now have it generate an HTML TABLE, presumably
6792 for integration into other HTML sources. David updated the ab man page
6793 as well and added some missing descriptions. Thanks!
6794 [David N. Welton <davidw@prosa.it>]
6796 *) Win32: The filename validity checker now allows filenames containing
6797 characters in the range 0x80 to 0xff (for example accented characters).
6798 [Paul Sutton] PR#3890
6800 *) Added conditional logging based upon environment variables to
6801 mod_log_config. mod_log_referer and mod_log_agent
6802 are now deprecated. [Ken Coar]
6804 *) Allow apache acting as a proxy server to relay the real
6805 reason of a failure to a client rather than the "internal
6806 server error" it does currently. The general exposure mechanism
6807 can be triggered by any module by setting the "verbose-error-to"
6808 note to "*"; this allows more than just proxy errors to be exposed.
6809 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
6811 *) Moved man pages for ab and apachectrl to section 8.
6812 [Wilfredo Sanchez, Roy Fielding]
6814 *) Added -S option to install.sh so that options can be passed to
6815 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
6817 *) Tweak modules Makefile generated by Configure so that it handles
6818 the test case of no modules being selected. [chaz@reliant.com]
6820 *) Added a <LimitExcept method ...> sectioning directive that allows
6821 the user to assign authentication control to any HTTP method that
6822 is *not* given in the argument list; i.e., the logical negation
6823 of the <Limit> directive. This is particularly useful for controlling
6824 access on methods unknown to the Apache core, but perhaps known by
6825 some module or CGI script. [Roy Fielding, Tony Finch]
6827 *) Prevent apachectl from complaining if the PIDFILE exists but
6828 does not contain a process id, as might occur if the server is
6829 being rapidly restarted. [Wilfredo Sanchez]
6831 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
6833 *) Entity tag comparisons for If-Match and If-None-Match were not being
6834 performed correctly -- weak tags might cause false positives. Also,
6835 strong comparison wasn't properly enforced in all cases.
6836 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
6838 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
6841 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
6842 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
6844 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
6845 to util.c for parsing an HTTP header field value to extract the next
6846 list item, taking into account the possible presence of nested comments,
6847 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
6848 insignificant whitespace and lowercases non-quoted tokens.
6849 [Roy Fielding] PR#2065
6851 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
6852 code different from 500. This allows the proxy to, e.g., return
6853 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
6855 *) Fix ordering of language variants for the case where the traditional
6856 negotiation algorithm is being used with multiple language variants
6857 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
6859 *) Do not round the TCN quality calculation to 5 decimal places,
6860 unlike RFC 2296, because the calculation might need 12 decimal places
6861 to get the right result. [Roy Fielding]
6863 *) Remove unused code to disable transparent negotiation when
6864 negotiating on encoding only, as we now handle encoding too
6865 (though this is nonstandard for TCN), remove charset=ISO-8859-1
6866 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
6867 some debugging statements within mod_negotiation. [Koen Holtman]
6869 *) Fixed a rare memory corruption possibility in mod_dir if the index
6870 file is negotiable and no acceptable variant can be found.
6871 [Dean Gaudet, Roy Fielding, Martin Kraemer]
6873 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
6874 searching the Win32 registry for script interpreters.
6877 *) Win32: The compiled-in default filename for the error log is now
6878 error.log, which matches the default in the distributed httpd.conf.
6881 *) Win32: Any error messages from -i or -u command line options are now
6882 displayed on the console output rather than sent to the error log.
6883 Also the "Running Apache..." message is not output unless Apache is
6884 going to serve requests. [Paul Sutton]
6886 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
6887 and use a private significator ('$apr1$') to mark passwords as
6888 being smashed with our own algorithm. Also abstract the password
6889 checking into a new ap_validate_password() routine. [Ken Coar]
6891 *) Win32: The filename validity checker now allows "COM" but refuses
6892 access to "COM1" through "COM4". This allows filenames such
6893 as "com.name" to be served. [Paul Sutton] PR#3769.
6895 *) BS2000: Adapt to the new ufork() system call interface which will
6896 make subtasking easier on the OSD/POSIX mainframe environment.
6899 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
6900 ap_compat.h. [David White <david@persimmon.com>] PR#3725
6902 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
6903 use `.db' instead of `.pag' not only for FreeBSD, but also when
6904 the NDBM library looks like Berkeley-DB based.
6905 [Ralf S. Engelschall] PR#3773
6907 *) Add ability to handle DES or MD5 authentication passwords.
6908 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
6910 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
6912 *) SECURITY: Avoid some buffer overflow problems when escaping
6913 quoted strings. (This overflow was on the heap and we believe
6914 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
6916 *) Let src/Configure be aware of CFLAGS options starting with plus
6917 signs as it's the case for the HP/UX compiler.
6918 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
6920 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
6921 and check to see if the tar we wind up with supports '-h'.
6922 [Jim Jagielski] PR#3671
6924 *) A consistent and conservative style for all shell scripts has been
6925 implemented. Basically, all shell string tests use the traditional
6926 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
6927 to protect against bare null variable strings (ie: wrapping both
6928 sides with double quotes and prepending 'x'). 'x' was chosen
6929 because it's more universal and hopefully easier for old shell
6930 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
6933 *) The status module now prints out both the main server generation as
6934 well as the generation of each process. Also, the vhost info is
6935 printed with '?notable'. [Jim Jagielski]
6937 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
6938 and this makes its functions available to things in src/support.
6941 Changes with Apache 1.3.4
6943 *) Renamed macros status_drops_connection to ap_status_drops_connection
6944 and vestigial scan_script_header to ap_scan_script_header_err,
6945 mostly for aesthetic reasons. [Roy Fielding]
6947 *) The query switch "httpd -S" didn't exit after showing the
6948 vhost settings. That was inconsistent with the other query functions.
6951 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
6952 filename to the end of the STANDARD_MODULE_STUFF. Its
6953 presence at the beginning prevented reporting of the filename
6954 for modules compiled before 1 January 1999. [Ken Coar]
6956 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
6957 to detect and prevent access to special DOS device file names.
6958 [Paul Sutton, Ken Parzygnat]
6960 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
6961 and Makefile_win32_debug.txt (debug build) that work on Win95.
6962 Run each of the following from the src directory:
6963 nmake /f Makefile_win32.txt # compiles normal build
6964 nmake /f Makefile_win32.txt install # compiles and installs
6965 nmake /f Makefile_win32.txt clean # removes compiled junk
6966 nmake /f Makefile_win32_debug.txt # compiles debug build
6967 nmake /f Makefile_win32_debug.txt install
6968 nmake /f Makefile_win32_debug.txt clean
6971 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
6972 to build binary distributions. [Lars Eilebrecht]
6974 *) IndexOptions SuppressColumnSorting only turned off making
6975 the column headers anchors; you could still change the display
6976 order by manually adding a '?N=A' or similar query string to the
6977 URL. Now SuppressColumnSorting locks in the sort order so
6978 it can't be overridden this way. [Ken Coar]
6980 *) Added IndexOrderDefault directive to supply a default sort order
6981 for FancyIndexed directory listings. [Ken Coar] PR#1699
6983 *) Change the ap_assert macro to a variant that works on all platforms.
6984 [Richard Prinz <richard.prinz@cso.net>] PR#2575
6986 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
6987 search for an underscore on dlsym() (as it's already the case
6988 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
6990 *) Small fix for mod_env.html: The module was documented as to be _not_
6991 compiled into Apache per default, although it _IS_ compiled into
6992 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
6994 *) Instead of fixing a bug in the generation procedure for config.status (a
6995 backslash was missing) we remove the bug together with it's complete
6996 context because the special cases of the past can now no longer occur
6997 because of the recent magic for the --with-layout default.
6998 [Ralf S. Engelschall] PR#3590
7000 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
7001 making sure the src/support/ tools are _forced_ to be build last (they
7002 depend on other libraries).
7003 [Markus Theissinger <markus.theissinger@gmx.de>]
7005 *) Fix installation procedure: Now that os-inline.c is actually used (a
7006 recently fixed bug prevented this) we need to also install os-include.c
7007 in addition to os.h into the PREFIX/include/ location or building of
7008 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
7010 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
7011 allow us to distinguish between a garbled DSO (or even a file which isn't
7012 an Apache module DSO at all) and a DSO which doesn't match the current
7013 Apache API. [Ralf S. Engelschall] PR#3152
7015 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
7016 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
7017 match case insensitive (this especially avoids nasty patterns like
7018 `[tT][eE][sS][tT]'). Second two additional internal map functions
7019 `escape' and `unescape' were added which can be used to escape/unescape
7020 to/from hex-encodings in URLs parts (this is especially useful in
7021 combination with map lookups).
7022 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
7024 *) Renamed the macro escape_uri() to ap_escape_uri() which was
7025 forgotten (because it was a macro) in the symbol renaming process.
7026 [Ralf S. Engelschall]
7028 *) Fix some inconsistencies related to the scopes of directives. The only
7029 user visible change is that the directives `UseCanonicalName' and
7030 `ContentDigest' now use the (more correct) `Options' scope instead of
7031 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
7033 *) Using DSO, the Server token was being mangled. Specifically, the
7034 module's token was being added first before the Apache token. This
7035 has been fixed. [Jim Jagielski]
7037 *) Major overhaul of mod_negotiation.c, part 2.
7038 - properly handle "identity" within Accept-Encoding.
7039 - allow encoded variants in RVSA negotiation and let them appear in
7040 the Alternates field using the non-standard "encoding" tag-list.
7041 - fixed both negotiation algorithms so that an explicitly accepted
7042 encoding is preferred over no encoding if "identity" is not
7043 included within Accept-Encoding.
7044 - added ap_array_pstrcat() to alloc.c for efficient concatenation
7045 of large substring sequences.
7046 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
7049 *) Major overhaul of mod_negotiation.c, part 1.
7050 - cleanups to mod_negotiation comments and code structure
7051 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
7052 support for everything in the upcoming HTTP/1.1
7053 revision (draft-ietf-http-v11-spec-rev-06.txt).
7054 - language tag matching also handles tags with more than 2
7056 - empty Accept, Accept-Language, Accept-Charset headers are
7057 processed correctly; previously an empty header would make all
7058 values acceptable instead of unacceptable.
7059 - allowed for q values in Accept-Encoding
7060 - added support for transparent content negotiation (rfc2295 and
7061 rfc2296) (though we do not implement all features in these drafts,
7062 e.g. no feature negotiation). Removed old experimental version.
7063 - implemented 'structured entity tags' for better cache correctness
7064 (structured entity tags ensure that caches which can deal with Vary
7065 will (eventually) be updated if the set of variants on the server
7067 - this involved adding a vlist_validator element to request_rec
7068 - this involved adding the ap_make_etag() function to the global API
7069 - modified guessing of charsets used by Apache negotiation algorithm
7070 to guess 'no charset' if the variant is not a text/* type
7071 - added code to sort multiviews variants into a canonical order so that
7072 negotiation results are consistent across backup/restores and mirrors
7073 - removed possibility of a type map file resolving to another type map
7074 file as its best variant
7075 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
7077 *) RFC2396 allows the syntax http://host:/path (with no port number)
7078 but the proxy disallowed it (ap_proxy_canon_netloc()).
7079 [David Kristol <dmk@bell-labs.com>] PR#3530
7081 *) When modules update/modify the file name in the configfile_t structure,
7082 syntax errors will report the updated name, not the original one.
7083 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
7085 *) Correct some filename case assumptions from WIN32 to
7086 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
7088 *) For %v log ServerName regardless of the UseCanonicalName
7089 setting (similarly for %p). [Dean Gaudet]
7091 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
7092 rather late (too late for some invocations of TestCompile).
7093 This improves the make environment available to TestCompile and
7094 the *.module scripts. [Martin Kraemer]
7096 *) The hashbang emulation code in ap_execve.c would interpret
7097 #!/hashbang/scripts correctly, but failed to fall back to a
7098 standard shell for scripts which did NOT start with #!
7099 Now SHELL_PATH is started in these cases. [Martin Kraemer]
7101 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
7104 *) Update APXS manual page: some -q option arguments were missing
7105 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
7107 *) Cleanup the command line options: `-?' was documented to show
7108 the usage list but does it with an error because `?' is not a valid
7109 command. OTOH a lot of users expect `-h' to print such a usage list and
7110 instead are annoyed for ages by our huge unreadable list of directives.
7111 So we now changed the command line options this way:
7113 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
7114 very similar to the popular linker option.
7116 Intent: while -l gives the small list of modules, -L now gives the
7117 large list of directives implemented by these modules. This is also
7118 consistent with -v (short version info) and -V (large version info).
7120 Intent: it's now the expected option ;-)
7121 The manual page was adjusted accordingly.
7122 [Ralf S. Engelschall] PR#2714
7124 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
7125 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
7127 *) Removed recently introduced bugs and disfigurements in APACI:
7128 o fixed argument line processing: using $args was broken: It was not
7129 initialized and using args="$args $apc_option" and even args="$args
7130 \"$apc_option\"" fails in the second processing round for any arguments
7131 containing whitespaces. The only correct way is to use the construct
7132 "$@" (but not possible here) or iterate _both_ times over the implicit
7133 argument line (no argument to for-loop) which is what we now use.
7134 o make --with-layout=Apache the default without creating
7135 redundancy (copying the --with-layout block in the argument parsing
7136 loop). We achieve this by using the "$@" construct together with the
7137 `set' command to prepend --with-layout=Apache to the command line in
7138 case --with-layout is not used.
7139 o fixed auto-suffix handling now that config.layout exists.
7140 Paths which are auto-suffixed are marked with a trailing plus sign in
7141 config.layout and every path now can be marked this way (not only the
7142 four paths for which we do it currently). Additionally the suffix is
7143 no longer a static one. Instead it's now `/<target>' where <target> is
7144 the argument of the --target option or per default `httpd'.
7145 o allow also tabs (and only spaces) where we match whitespaces
7146 o various fixes and cleanups related to used shell coding style
7147 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7148 o trimmed output of --help to fit into 80 columns
7149 [Ralf S. Engelschall]
7151 *) Added two new core API functions, ap_single_module_configure() and
7152 ap_single_module_init(), which are now used by mod_so to configure a module
7153 after loading. [Ralf S. Engelschall]
7155 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
7156 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
7157 of ap_config.h to allow serialized accept for multiport listens.
7158 [Roy Fielding, Curt Sampson] PR#3120
7160 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
7161 of ap_config.h that would skip several defines if DEFAULT_GROUP
7162 was overridden. [Roy Fielding]
7164 *) PORT: The I86 version of DGUX has support for strncasecmp and
7165 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
7167 *) Fix ordering of definitions in ap_config.h so that ap_inline is
7168 defined before it might be used. [Victor Khimenko]
7170 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
7171 [Tom Serkowski <tks@bsdi.com>] PR#3453
7173 *) Make generation of src/Configuration.apaci more robust: It failed to
7174 differenciate between modules when one module name was a postfix of
7175 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
7176 just XXX (think about totally non-standard names like "apache_ssl", too).
7177 [Ralf S. Engelschall] PR#3380
7179 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
7180 since 1.3b7) and make whitespace handling more robust (it failed horrible
7181 when whitespaces were present in the arguments of -D options).
7182 [Ralf S. Engelschall] PR#3240
7184 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
7185 creates an external package shadow tree in DIR before the local build
7186 shadow tree is generated under DIR. This way one can have the extracted
7187 Apache distribution tree read-only on NFS or CDROM and still build Apache
7188 from these sources. An automatically triggered VPATH-like mechanism is
7189 provided through the TOP variable, too.
7190 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
7192 *) Fix negotiation so that a Vary response header is correctly
7193 generated when, for a particular dimension, variants only vary
7194 in having or not having a value for that dimension. [Paul Sutton]
7196 *) Fix negotiation so that we prefer an encoded variant over an
7197 unencoded variant if the user-agent explicitly says it can
7198 accept that encoding. Previously we always preferred the unencoded
7200 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
7202 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
7203 and the usage page was inconsistent with the functionality and manpage.
7204 [Ralf S. Engelschall]
7206 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
7207 They can occur multiple times and their arguments (`xxx') are passed AS
7208 IS to the compiler/linker command. [Ralf S. Engelschall]
7210 *) Fixed possible (but harmless in practice) bug in the DBM lookup
7211 procedure of mod_rewrite: very long keys were truncated.
7212 [Ralf S. Engelschall]
7214 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
7215 identifier, currently "Apache" and "GNU" are pre-defined in the file
7216 config.layout. Custom layouts are possible by using FILE:ID as the
7217 argument where the layout ID is taken from FILE.
7219 The config.layout file consists of <Layout ID>..</Layout> sections
7220 where inside those sections "path_variable: path_value" pairs can be

7223 *) Add a DefaultLanguage directive so that files missing a language
7224 extension (e.g., .fr, .de) can be labelled as being some other
7225 default language. DefaultLanguage can appear in <Directory> and
7226 <Files> containers as well as .htaccess files. [Paul Sutton]
7229 *) Fix TARGET configuration when configuring and installing using
7230 APACI configure. TARGET now defines the basename of the configuration
7231 file, startup script, manual page, etc. log_error_core() now reports
7232 the server binary name given by argv[0]. TARGET can now also be defined
7233 with --target=TARGET parameter passed to APACI configure.

7236 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
7237 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]
7239 *) ap_md5_binary() was using sprintf() rather than a table lookup
7240 to convert binary bytes to hex digits.

7256 notice to the error log. It is not possible to send a 401 response
7257 and a redirect at the same time. [Lars Eilebrecht]
7259 *) Fallback to native compilers for IRIX-32 platform. It seems that
7260 a gcc 2.8.1 compiled apache is logging client addresses with all
7261 bits set (255.255.255.255). This is the second such problem caused
7262 by gcc 2.8.1 compiler. The first being broken semaphore locking.
7265 *) Updated mime.types to reflect current Internet media types
7266 and include a URL to the registry.

7270 an infinite loop of recursive SSI includes. [Marc Slemko] PR#3323

7273 used to set the document root directory (DOC_ROOT) and the suexec
7274 logfile (LOG_EXEC), respectively. Additionally the --layout option
7275 was changed to show more information about the suEXEC setup.

7278 *) Added the last two WebDAV status codes of 424 (Failed Dependency)
7279 and 507 (Insufficient Storage) for use by third-party modules.
7282 *) Enabled all of the WebDAV method names for use by third-party
7283 modules, Limit, and Script directives. That includes PATCH,
7284 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
7285 Improved mod_actions.c so that it can use any of the methods
7286 defined in httpd.h. Added ap_method_number_of(method) for

7310 the interpreter and the Win32 error code returned. [Marc Slemko]
7312 *) Disable sending of error-notes on a 500 (Internal Server Error) response
7313 since it often includes file path info. Enable sending of error-notes
7314 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
7316 *) http_config.c would respond with 501 (Method Not Implemented) if a
7317 content type handler was specified but could not be found, which
7318 should have been a 500 response. Likewise, mod_proxy.c would responsd
7319 with a 501 if the URI scheme is unrecognized instead of the correct
7320 response of 403 (Forbidden). [Roy Fielding]
7322 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
7323 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
7325 *) Fix in mod_autoindex: for files where the last modified time stamp was
7326 unavailable, an empty string was printed which was 2 bytes short.
7327 The size and description columns were therefore not aligned correctly.

7335 scoreboard file and avoid a string copy (as well as allow some
7336 further future enhancements). [Harrie Hazewinkel
7337 <harrie.hazewinkel@jrc.it>]
7339 *) Add APACI --permute-module=foo:bar option which can be used to
7340 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
7341 in the Configuration[.apaci] file. Two special and important variants are
7342 supported for the option argument: first BEGIN:foo which permutes module
7343 mod_foo with the begin of the module list, i.e. it `moves' the module to
7344 the begin of the list (gives it lowest priority). And second foo:END
7345 which permutes mod_foo with the end of the module list, i.e. it `moves'
7346 the module to the end of the list (gives it highest priority).

7388 *) Add a "default-handler" handler that calls the default_hander()
7389 function which is normally called for static content. This allows
7390 you to override a specific handler. [Marc Slemko]

7393 hard-coded syntax check with a call to a routine we already created to
7394 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
7396 *) Log an error if we encounter a malformed "require" directive
7397 in mod_auth if we know that we know that no other module can
7398 deal with it. [Marc Slemko]
7400 *) Remove ap_private_extern method of hiding conflicting symbols
7401 on the NEXT platform because it is not correct for all versions,
7402 and the versions for which it is correct are unknown.

7415 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
7417 Changes with Apache 1.3.3
7419 *) Added a complete implementation of the Expect header field as
7420 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
7421 response when we already know the final status, which is mighty
7422 useful for PUT responses that result in 302 or 401. [Roy Fielding]
7424 *) Remove extra trailing whitespace from the getline results as part
7425 of the protocol processing, which is extra nice because it works
7426 between continuation lines, is almost no cost in the normal case
7427 of no extra whitespace, and saves memory. [Roy Fielding]
7429 *) Added new HTTP status codes and default response bodies from the
7430 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
7431 HTTP Extension Framework (510) specifications. Did not add the
7432 WebDAV 424 and 425 codes because they are bogus. We don't use any
7433 of these codes yet, but they are now available to 3rd-party modules.
7436 *) Fix a possible race condition between timed-out requests and the
7437 ap_bhalfduplex select that might result in an infinite loop on
7438 platforms that do not validate the descriptor. [Roy Fielding]

7549 You now must define a BS2000Account name for the server User.
7550 This has fewer security implications than the old approach.
7553 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
7554 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
7555 platform to make the braindead HPUX linker happy. Notice, for the module
7556 DSOs we don't have to use this, because these are loaded manually (and
7557 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

7568 *) Make PrintPath work generically instead of having one version
7569 strictly for OS/2. [Jim Jagielski, Brian Havard]
7571 *) Fix the recently introduced C header file checking: We now use the C
7572 pre-processor pass only (and no longer the complete compiler pass) to
7573 determine whether a C header file exists or not. Because only this way
7574 we're safe against inter-header dependencies (which caused horrible
7575 portability problems). The only drawback is that we now have a CPP
7576 configuration variable which has to be determined first (we do a similar
7577 approach as GNU Autoconf does here). When all fails the user still has
7578 the possibility to override it manually via APACI or src/Configuration.
7579 As a fallback for the header check itself we can directly check the
7580 existance of the file under /usr/include, too.

7613 because our GuessOS is still unaware of Digital UNIX versions and the
7614 -msym is just to optimize the DSO statup time a little bit it's safe and
7615 best when we leave it out now. [Ralf S. Engelschall] PR#2969

7620 (instead it directly passes through the message to be formatted to the
7621 real internal formatting function). [Ralf S. Engelschall] PR#2941
7623 *) Allow "Include" directives anywhere in the server config
7624 files (but not .htaccess files). [Ken Coar] PR#2727
7626 *) The proxy was refusing to serve CONNECT requests except to
7627 port 443 (https://) and 563 (snews://). The new AllowCONNECT
7628 directive allows the configuration of the ports to which a
7629 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
7631 *) mod_expires will now act on content that is not sent from a file
7632 on disk. Previously it would never add an Expires: header to
7633 any response that did not come from a file on disk; the only
7634 case where it still doesn't (and can't) add one for that type of
7635 content is if you are using a modification date based setting.
7636 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
7638 *) Problems encountered during .htaccess parsing or CGI execution
7639 that lead to a "500 Server Error" condition now provide explanatory
7640 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
7643 *) Add NameWidth keyword to IndexOptions directive so that the

7647 *) Recognize lowercase _and_ uppercase `uname' results under
7648 SCO OpenServer. [David Coelho <drc@ppt.com>]
7650 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
7651 a common problem of (mis-administrated?) IIS servers, make the apache
7652 proxy immune to these errors (and ignore the duplicates, but log
7653 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
7655 *) The <IfModule and <IfDefine block starting directives now only
7656 allow exactly one argument. Previously, the optional negation
7657 character '!' could be separated by whitespace without a syntax
7658 error being reported, albeit defeating the IfModule functionality
7659 (enclosed directives would ALWAYS be executed). By using the
7660 stricter syntax, these hard-to-track errors can be avoided.
7663 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
7664 cause the standalone FancyIndexing directive to logically OR
7665 into any existing IndexOptions settings rather than wiping
7666 them out. [Ken Coar]
7668 *) Changes in ftp proxy: make URL parsing simpler by using the
7670 + Add display of the "current directory" in cases where it's
7671 different from the supplied path (e.g., ftp://user@host/ lives
7672 in /home/user, not in /, therefore clicking on "../" in the
7673 starting directory might send us to /home/).
7674 + When ftp login fails, (esp. when a user name was part of the
7675 URL already), we now return [401 Unauthorized ] to allow the
7676 browser to pop up an authorization dialog. This makes passwords
7677 slightly less visible (they don't appear in the regular log files)
7678 and implements a functionality that other www proxy servers
7682 *) Triggered by the recent "Via:" header changes, the proxy module would
7683 dump core for replies with invalid headers (e.g., duplicate
7684 "HTTP/1.0 200 OK" lines). These errors are now logged and the
7685 core dump is avoided. Also, broken replies are not cached.

7711 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
7712 [Youichirou Koga <y-koga@jp.FreeBSD.ORG>] PR#2895
7714 *) Dynamically size the filename column of mod_autoindex output.
7717 *) Add the ability to do POST requests to the ab benchmarking tool.
7718 [Kurt Sussman <kls@best.com>] PR#2871
7720 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
7721 5 to 10 because there are some users out there who always have 5 to 8
7722 variables in one RewriteRule and had to patch mod_rewrite.h for every
7723 release. So 15 should be now more than enough, even for them. (I never
7724 needed more than 4 in my RewriteRules ;-)
7725 [Ralf S. Engelschall]
7727 *) Make the proxy generate and understand Via: headers
7730 *) Change the proxy to use tables instead of array_headers for
7731 the header lines. [Martin Kraemer]
7733 *) Make sure the config.status file is not overridden when just
7734 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
7736 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
7737 provide a way to trace API changes that add functionality but do
7738 not create a compatibility issue for precompiled modules, etc.
7739 See include/ap_mmn.h for more details. [Randy Terbush]
7741 *) Fix suexec installation under `make install root=xxx' situation.
7742 [Ralf S. Engelschall]
7744 *) Extend the output of the -V switch to include the paths of all
7745 compiled-in configuration files, if they were overridden at
7746 compile time, for least astonishment of the user.
7749 *) When READing a request in ExtendedStatus mode, the "old"
7750 vhost, request and client information is not displayed.
7753 *) STATUS is no longer available. Full status information now
7754 run-time configurable using the ExtendedStatus directive.
7757 *) SECURITY [CAN-1999-1199] (cve.mitre.org):
7758 Eliminate O(n^2) space DoS attacks (and other O(n^2)
7759 cpu time attacks) in header parsing. Add ap_overlap_tables(),
7760 a function which can be used to perform bulk update operations
7761 on tables in a more efficient manner.
7764 *) SECURITY: Added compile-time and configurable limits for
7765 various aspects of reading a client request to avoid some simple
7766 denial of service attacks, including limits on maximum request-line
7767 size (LimitRequestLine), number of header fields (LimitRequestFields),
7768 and size of any one header field (LimitRequestFieldsize). Also added
7769 a configurable directive LimitRequestBody for limiting the size of the
7770 request message body. [Roy Fielding]

7773 STATUS not defined. [Jim Jagielski]

7777 *) Enhance mod_speling so that CheckSpelling can be used in
7778 <Directory> containers and .htaccess files. [Ken Coar]
7780 *) API: new ap_custom_response() function for hooking into the
7781 ErrorDocument mechanism at runtime [Doug MacEachern]
7783 *) API: new ap_uuencode() function [Doug MacEachern]
7785 *) API: scan_script_header_err_core() now "public" and renamed
7786 ap_scan_script_header_err_core() [Doug MacEachern]
7788 *) The 'status' module will now show the process pid's and their
7789 state even without full STATUS accounting. [Jim Jagielski]
7791 *) Restore the client IP address to the error log messages, this
7792 was lost during the transition from 1.2 to 1.3. Add a new
7793 function ap_log_rerror() which takes a request_rec * and
7794 formats it appropriately. [Dean Gaudet] PR#2661
7796 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
7797 whitespace in input lines -- including within quoted strings.
7799 but leading and trailing whitespace should continue to be
7800 stripped [Martin Kraemer]
7802 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
7803 the ugly use of an env. variable and use command-line args for
7804 alternate $PATH. Make more like advanced 'type's as well.
7807 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
7808 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
7809 <alain.st-denis@ec.gc.ca>] PR#2736
7811 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
7813 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
7814 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
7815 directory was renamed to src/os/os2/ for consistency.
7816 [Brian Havard, Ralf S. Engelschall]
7818 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
7819 files (here modules) against other DSO files (here shared libraries).
7820 This is done by determining a subset of LIBS which can be safely used for
7821 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
7822 disabled for all platforms to avoid problems with this (experimental)
7823 rule. But we provide it now for those people how ran into problems and
7824 want to came out by forcing linking against DSOs.
7825 [Ralf S. Engelschall] PR#2587
7827 *) Fix suEXEC start message: Has to be of `notice' level to really get
7828 printed together with the standard startup message because the `notice'
7829 level is handled special inside ap_log_error() for startup messages.
7830 [Ralf S. Engelschall] PR#2761 PR#2761 PR#2765
7832 *) Add correct `model' MIME types from RFC2077 to mime.types file.

7836 [Youichirou Koga <y-koga@jp.FreeBSD.org>, Ralf S. Engelschall] PR#2756
7838 *) Allow ap_read_request errors to propagate through the normal request
7839 handling loop so that the connection can be properly closed with
7840 lingering_close, thus avoiding a potential TCP reset that would
7841 cause the client to miss the HTTP error response. [Roy Fielding]
7843 *) One more portability fix for APACI shadow tree support: Swap order of awk
7844 and sed in top-level configure script to avoid sed fails on some
7845 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
7846 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729

7849 [MATSUURA Takanori <t-matsuu@protein.osaka-u.ac.jp>]
7851 *) Fix a segfault in the proxy on OS/2. [Brian Havard]
7853 *) Fix Win32 part of ap_spawn_child() by providing a reasonable child_info
7854 structure instead of just NULL. This fixes at least the RewriteMap
7855 programs under Win32. [Marco De Michele <mdemichele@tin.it>] PR#2483

7866 of the `proxy' (`[P]') feature. [Ralf S. Engelschall] PR#2679
7868 *) Fix `install-includes' sub-target of `install' target in top-level
7869 Makefile.tmpl: The umask+cp approach didn't work as expected (especially
7870 for users which extracted the distribution under 'umask 077'), so replace
7871 it by an explicit cp+chmod approach.
7872 [Richard Lloyd, Curt Sampson, Ralf S. Engelschall] PR#2656 PR#2626

7878 *) Use a more straight forward and thus less problematic Sed command in
7879 src/helper/mkdir.sh script. [Ralf S. Engelschall]
7881 *) Make sure the `configure' scripts doesn't fail when trying to guess the
7882 domainname of the machine and there are multiple `domainname' and
7883 `search' entries in /etc/resolv.conf.

7894 engine does any manipulations or decisions based upon request fields.
7897 *) Document the special APACI behavior for installation paths where
7898 ``/apache'' is appended to paths under some (well defined, of course)
7899 situations to prevent pollution of system locations with Apache files.
7900 [Ralf S. Engelschall] PR#2660
7902 *) Fixed problem with buffered response message not being sent for
7903 the read_request error conditions of URI-too-long (414) and
7904 malformed header fields (400). [Roy Fielding] PR#2646
7906 *) Add support for the Max-Forwards: header line required by RFC2068 for
7907 the TRACE method. This allows apache to TRACE along a chain of proxies
7908 up to a predetermined depth. [Martin Kraemer]
7910 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled
7911 (compilers complained) and the .so.V.R.P filename extension was adjusted
7912 to correctly reflect the 1.3.2 version.

7942 the scheme://sitepart string only, or to omit the query string.
7945 *) WIN32: Canonicalize ServerRoot before checking to see if it
7946 is a valid directory. The failure to do this caused certain
7947 ServerRoot settings (eg. "ServerRoot /apache") to be improperly
7948 rejected. [Marc Slemko]
7950 *) Global renaming of C header files to both get rid of conflicts with third
7951 party packages and to again reach consistency:
7952 1. conf.h -> ap_config.h
7953 2. conf_auto.h -> ap_config_auto.h \ these are now merged
7954 3. ap_config.h -> ap_config_auto.h / in the config process
7955 4. compat.h -> ap_compat.h
7956 5. apctype.h -> ap_ctype.h
7957 Backward compatibility files for conf.h and compat.h were created.
7959 *) mod_mmap_static will no longer take action on requests unless at
7960 least one "mmapfile" directive is present in the configuration.
7961 This experimental module has to do some black magic to operate
7962 inside the current API and thus creates side-effects for other
7963 modules under some circumstances.
7964 [Ralf S. Engelschall]

7967 to avoid problems under brain-dead platforms like Digital UNIX (OSF1).
7968 [Ralf S. Engelschall] PR#2596
7970 *) mod_rewrite created RewriteLock files under the UID of the parent
7971 process, thus the child processes had no write access to the files.
7972 Now a chown() is done on the file to the uid of the children,
7973 if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341
7975 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
7976 TestCompile) instead of defining them manually in conf.h based on less
7977 accurate platform definitions. This way we no longer have to fiddle with
7978 OS-type and/or OS-version identifiers to discover whether a system header
7979 file exists or not. Instead we now directly check for the existence of
7980 those esoteric ones.

7985 field with "^$". [Ken Coar]
7987 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
7988 modules to load their own modules dynamically. This improves mod_perl
7989 and mod_php3 when these modules are loaded dynamically into Apache.
7992 *) Cache a proxied request in the event that the client cancels the
7993 transfer, provided that the configured percentage of the file has
7994 already been transfered. It works for HTTP transfers only. The
7995 new configuration directive is called CacheForceCompletion.

8021 if the installation prefix didn't already contain "apache", but
8022 it should be because the DSO files are Apache-specific. Now

8077 directory, bail out of the request with an error message. [W G Stoddard]
8079 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
8080 these are treated by Win32 as if they are ".." but are not detected by

8112 as <IfModule>..</IfModule> sections) which can be used to skip or process
8113 contained commands dependend of ``-D PARAMETER'' options on the command
8114 line. This can be used to achieve logical conditions like <IfDefine
8115 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)

8133 *) Improve performance of directory listings (mod_autoindex) by comparing
8134 integer keys (last-modified and size) as integers rather than converting
8135 them to strings first. Also use a set of explicit byte tests rather
8136 than strcmp() to check for parent directory-ness of an entry. Oh, and
8137 make sure the parent directory (if displayed) is *always* listed first
8138 regardless of the sort key. Overall performance winnage should be good
8139 in CPU time, instruction cache, and memory usage, particularly for large
8140 directories. [Ken Coar]
8142 *) Add a tiny but useful goody to APACI's configure script: The generation
8143 of a config.status script (as GNU Autoconf does) which remembers the used
8144 configure command and hence can be used to restore the configuration by
8145 just re-running this script or for remembering the configuration between

8149 *) Add httpd -t (test) option for running configuration syntax tests only.
8150 If something is broken it complains and exits with a return code
8151 non-equal to 0. This can be used manually by the user to check the Apache
8152 configuration after editing and is also automatically used by apachectl
8153 on (graceful) restart command to make sure Apache doesn't die on restarts
8154 because of a configuration which is now broken since the last (re)start.
8155 This way `apachectl restart' can be used inside cronjobs without having
8156 to expect Apache to be falling down. Additionally the httpd -t can be run
8157 via `apachectl configtest'.

8216 *) Change "Options None" to "Options FollowSymLinks" in the
8217 <Directory /> section of the default access.conf-dist
8218 (and -win even though it doesn't matter there). This has better
8219 performance, and more intuitive semantics. [Dean Gaudet]

8226 [Jens-Uwe Mager <jum@helios.de>]
8228 *) Workaround for configure script and old `test' commands which do not
8229 support the -x flag (for instance under platforms like Ultrix). This is
8230 solved by another helper script findprg.sh which searches for Perl and
8231 Awk like PrintPath but _via different names_.

8256 Changes with Apache 1.3.0
8258 *) Using a type map file as a custom error document was not possible.

8261 *) Avoid problems with braindead Awks by additionally searching for gawk
8262 and nawk in APACI's configure script.

8265 *) Rename md5.h to ap_md5.h to avoid conflicts with native MD5 on
8266 some systems. [Randy Terbush]
8268 *) Change usage of perror()+fprintf(stderr,...) in mod_rewrite to
8269 more proper ap_log_error() variants.
8270 [Ralf S. Engelschall]
8272 *) Make sure the argument for the --add-module option to APACI's configure
8273 script is of type [path/to/]mod_xxx.c because all calculations inside
8274 configure and src/Configure depend on this.
8275 [Ralf S. Engelschall] PR#2307
8277 *) Changes usage of perror/fprintf to stderr to more proper ap_log_error

8291 *) Propagate environment to CGI scripts correctly in Win32.
8292 [W G Stoddard <wgstodda@us.ibm.com>] PR#2294
8294 *) Some symbol renaming:
8295 ap_spawn_child_err became ap_spawn_child
8296 ap_spawn_child_err_buff became ap_bspawn_child
8297 spawn_child was obsoleted and moved to compat.h
8300 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
8301 programs: ap_spawn_child_err() is used and the Win32 case now uses
8302 CreateProcess() instead of a low-level execl() (which caused problems in
8303 the past under Win32).
8304 [Ralf S. Engelschall]
8306 *) A few cosmetics and trivial enhancements to APXS to make the
8307 generated Makefile more user friendly. [Ralf S. Engelschall]
8309 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
8310 was updated to use the normal apache error processing, thereby allowing
8311 proxy errors to be treated by ErrorDocument's as well. For this
8312 purpose, a new module-to-core communication variable "error-notes"
8313 was introduced; the proxy (and possibly other modules) communicates
8314 its error text using this variable. Its content is copied to a new
8315 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
8316 The old proxy special error routine ap_proxy_log_uerror()
8317 was replaced by regular ap_log_error() calls, many messages were made
8319 [Martin Kraemer] PR#494, 1259
8321 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
8324 *) Transform the configure message "You need root privileges for suEXEC"
8325 from a fatal error into a (more friendly) warning because the building
8326 ("make") of Apache we can allow, of course. Root privileges are needed
8327 only for the installation step ("make install"). So make sure the
8328 user is aware of this fact but let him proceed as long as he can.
8329 [Ralf S. Engelschall] PR#2288
8331 *) Renamed three more functions to common ap_ prefix which we missed at the
8332 Big Symbol Renaming because they're #defines and not real C functions:
8333 is_default_port(), default_port(), http_method().
8334 [Ralf S. Engelschall]
8336 *) A zero-length name after a $ in an SSI document should cause
8337 just the $ to be in the expansion. This was broken during the
8338 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
8340 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
8341 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252

8344 used under AIX) because of recent changes to function names.
8345 [Ralf S. Engelschall]
8347 Changes with Apache 1.3b7
8349 *) Make sure a MIME-type can be forced via a RewriteRule even when no
8350 substitution takes place, for instance via the following rule:
8351 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
8352 requested by users in the past to force a single script without a .cgi
8353 extension and outside any cgi-bin dirs to be executed as a CGI program.
8354 [Ralf S. Engelschall] PR#2254
8356 *) A fix for protocol issues surrounding 400, 408, and
8357 414 responses. [Ed Korthof]
8359 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
8361 *) Fix discrepancy in proxy_ftp.c which was causing failures when
8362 trying to connect to certain ftpd's, such as anonftpd.
8363 [Rick Ohnemus <rick@ecompcon.com>]
8365 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
8366 logfile instead of fiddling around itself with child spawning stuff.
8367 [Ralf S. Engelschall]
8369 *) Made RefererIgnore case-insensitive.
8371 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
8374 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
8375 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
8378 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
8380 *) Fix support script `dbmmanage': It was unable to handle some sort
8381 of passwords, especially passwords with "0" chars.
8382 [Ralf S. Engelschall] PR#2242
8384 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
8385 [Ben Laurie] PR#2238
8387 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
8388 library), so CGI handling has been changed to use Win32 native handles
8389 instead of C file descriptors.
8390 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
8392 *) The proxy cache would store an incorrect content-length in the cached
8393 file copy after a cache update. That resulted in repeated fetching
8394 of the original copy instead of using the cached copy.
8395 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
8397 *) The Makefiles assumed that DSO files are build via $(LD). This
8398 is broken for two reasons: First we never defined at least LD=ld
8399 somewhere to make sure this works (it was silently assumed that most Make
8400 provide a built-in LD definition - ARGL!) and second using the generic LD
8401 variable is not the truth. Instead a special variable named LD_SHLIB is
8402 reasonable because although "ld" is usually the default, the command for
8403 building DSO files can be "libtool" or even "cc" on some systems.
8404 [Ralf S. Engelschall]
8406 *) Replace the AddVersionPlatform directive with ServerTokens which
8407 provides for more control over the format of the Server:
8408 header line. SERVER_SUBVERSION is no longer supported;
8409 all module should use the ap_add_version_component()
8410 API function instead. [Jim Jagielski]
8412 *) Support for the NCR MP/RAS 3.0
8413 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
8415 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
8416 not retrieved in src/Configure and thus was not useable.
8417 [Ralf S. Engelschall]
8419 *) Various Makefile consistency cleanups:
8420 - make OSDIR also automatically be relative to src/ like INCDIR
8421 - SUBDIRS is now generated in src/Makefile only and not in
8422 Makefile.config because it is a local define for this location.
8423 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
8424 any Makefile but make sure that at least the "-K inline" is kept in
8426 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
8427 - updated the dependencies theirself
8428 - removed not existing SHLIB variable from "clean" targets
8429 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
8430 already exists and OBJS_PIC are also just plain objects and have not
8431 directly to do with "shared" things. The only difference is that they
8432 contain PIC. So OBJS_PIC is the more canonical name.
8433 - Updated the Makefile-dependency lines for OBJS_PIC
8434 - Removed the Makefile-dependency line in Configure to avoid double
8436 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
8437 of xxx.lo as GNU libtool does with its PIC objects
8438 - reduce local complexity in modules Makefile.tmpl by moving the last
8439 existing target "depend" to the generation section in Configure, too.
8440 - removed the historical $(SPACER) which was used in the past together
8441 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
8442 is no longer needed.
8443 - force the build and run of the gen_xxx programs under main/ as the
8444 first step before building the objects because it looks cleaner
8445 [Ralf S. Engelschall]
8447 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
8450 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
8453 *) WIN32: Don't force ISAPI headers to finish with \n.
8454 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
8456 *) When opening "configuration" files (like httpd.conf, htaccess
8457 and htpasswd), Apache will not allow them to be non-/dev/null
8458 device files. This closes a DoS hole. At the same time,
8459 we use ap_pfopen to open these files to handle timeouts.
8460 [Jim Jagielski, Martin Kraemer]
8462 *) Apache will now log the reason its httpd children exit if they exit
8463 due to an unexpected signal. (It requires a new porting define,
8464 SYS_SIGLIST, which if defined should point to a list of text
8465 descriptions of the signals available. See PORTING.) [Dean Gaudet]
8467 *) WIN32: chdir() doesn't make sense in a multithreaded environment
8468 like WIN32. Before, Win32 CGI's could have had sporadic failures
8469 if a chdir call from one thread was made between another chdir call
8470 and a spawn in another thread. So, for now don't chdir for CGI scripts
8471 in WIN32. The current CGI "spec" is unclear as to whether it's
8472 necessary. Long-term fix is to either serialize the chdir/spawn combo
8473 or use WIN32 native calls to spawn a process. This temp fix was
8474 necessary to remove this as a showstopper for 1.3's release.
8477 *) Cleanup the suEXEC support in APACI and make it more safe:
8478 1. Add big fat hint in INSTALL about risks and to read the
8479 htdocs/manual/suexec.html document before using the suexec-related
8481 2. Make sure the user has at least provided one --suexec-xxxx option
8482 (specifies suEXEC parameters) in addition to --enable-suexec option.
8483 If only --enable-suexec is given APACI stops with a hint to INSTALL
8484 and htdocs/manual/suexec.html documents.
8485 3. Provide two additional --suexec-xxxx options to make the suEXEC
8486 configuration complete (especially for package maintainers who else
8487 had to patch the source tree) by providing ways to configure minimal
8488 UID/GID and safe PATH, too.
8489 [Ralf S. Engelschall]
8491 *) Cleanup of the `configure --shadow' process:
8492 - make sure the configure script creates its temporary files in the
8493 shadow tree to avoid conflicts with parallel configure runs
8494 - removed unnecessary option "-r" from "rm" call for Makefiles
8495 - make sure the configure scripts creates the shadow-wrapper Makefile
8496 only when no shadow trees already exists
8497 - make sure "make distclean" removes the shadow-wrapper Makefile but only
8498 when no more shadow trees exists
8499 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
8500 as fast (in the past it needed 70sec, now it runs just 38sec)
8501 - make sure CVS does not complain about the created files
8502 Makefille.<gnutriple> and directories src.<gnutriple>
8503 [Ralf S. Engelschall]
8505 *) Added the ap_add_version_component() API routine and the
8506 AddVersionPlatform core directive. The first allows modules to
8507 declare themselves in the Server response header field value,
8508 augmenting the SERVER_SUBVERSION define in the Configuration file
8509 with run-time settings (more useful in a loadable-module environment).
8510 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
8511 into the server version string. [Ken Coar] PR#2056
8513 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
8516 *) Emit the "Accept-Range" header for the default handler.
8517 [Brian Behlendorf] PR#1464
8519 *) Add a note to httpd.conf-dist that apache will on some systems fail
8520 to start when the Group # is set to a negative or large positive value.
8523 *) Make sure the module execution order is correct even when some modules
8524 are loaded under runtime (`LoadModule') via the DSO mechanism:
8525 1. The list of loaded modules is now a dynamically allocated one
8526 and not the original statically list from modules.c
8527 2. The loaded modules are now correctly setup by LoadModule for
8528 later use by the AddModule command.
8529 3. When the DSO mechanism for modules is used APACI's `install'
8530 target now enables all created `LoadModule' lines per default because
8531 this is both already expected by the user _and_ needed to avoid
8532 confusion with the next point and reduces the Makefile.tmpl complexity
8533 4. When the DSO mechanism for modules is used, APACI's `install'
8534 target now additionally makes sure the module list is reconstructed
8535 via a complete `ClearModuleList+AddModule...' entry.
8536 5. The support tool `apxs' now also makes sure an AddModule command
8537 is added in addition to the LoadModule command.
8538 6. The modules.c generation was extended to now contain two
8539 comments to make sure no one is confused by the confusing terminology
8540 of loading/linking (we use load=link+load & link=activate instead of
8541 the obvious load=activate & link=link :-( )
8542 This way now there is no longer a difference under execution time between
8543 statically and dynamically linked modules.
8544 [Ralf S. Engelschall]
8546 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
8547 Big Symbol Renaming. [Ralf S. Engelschall]
8549 *) Add a comment to mod_example.c showing the format of a FLAG command
8552 *) Standardized the time format in mod_status to match that of other
8553 places in the code (e.g. DATE_GMT). PR#1551
8555 *) Fix handling of %Z in timefmt strings for those platforms with no time
8556 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
8559 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
8560 feature compatible with 'UseCanonicalName off' by changing
8561 r->server->server_hostname to ap_get_server_name(). And I changed some
8562 functions which use r->server->port to use ap_get_server_port() instead,
8563 because if there's no Port directive in the config r->server->port is 0.
8566 *) get/set_module_config are trivial enough to be better off inline. Worth
8567 1.5% performance boost. [Dean Gaudet]
8569 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
8570 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
8573 *) [BS2000 security] BS2000 needs an extra authentication to initialize
8574 the task environment to the unprivileged User id. Otherwise CGI scripts
8575 would have a way to gain super user access. [Martin Kraemer]
8577 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
8578 absolute path, only log base name of logging source as is done
8579 in unix. [Martin Kraemer]
8581 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
8582 the encoding type from the Accept-Encoding header (if it's there)
8583 and use it in the response, as that's probably what it'll be expecting.
8584 [Ronald.Tschalaer@psi.ch]
8586 *) Fix to mod_alias: translate_alias_redir is dealing with
8587 a URI, not a filename, so the check for drive letters for win32
8588 and emx is not necessary. [Dean Gaudet]
8590 *) WIN32: Allow .cmd as an executable extension.
8591 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
8593 *) Make Apache header files, and some variables, C++ friendly.
8594 [Michael Anderson's <mka@redes.int.com.mx>]
8596 *) Child processes can now "signal" (by exiting with a status
8597 of APEXIT_CHILDFATAL) the parent process to abort and
8598 shutdown the server if the error in the child process was
8599 fatal enough. [Jim Jagielski]
8601 *) mod_autoindex's find_itme() was sensitive to MIME type case.
8602 [Jim Jagielski] PR#2112
8604 *) Make sure the referer_log and agent_log entries in the default httpd.conf
8605 file are also adjusted for the actual relative installation paths.
8606 [Ralf S. Engelschall] PR#2175
8608 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
8610 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
8613 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
8614 Additionally the checks for finding the vendor DSO library were moved
8615 from mod_so.c to Configure because first it needs $PLAT etc. and second
8616 mod_so already uses an abstraction layer and does not fiddle with the
8617 vendor functions itself.
8618 [Jens-Uwe Mager, Ralf S. Engelschall]
8620 *) PORT: Some optimization defines for NetBSD
8621 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
8623 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
8624 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
8626 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
8627 AIX variants should work fine, too. Even AIX 3.x should work). This is
8628 accomplished by using the free DSO emulation code from Jens-Uwe Mager
8629 which we put into a os/unix/os-dso-aix.c file.
8630 [Ralf S. Engelschall]
8632 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
8633 that we should use NET_SIZE_T == int but the include files force size_t.
8634 [Ralf S. Engelschall]
8636 *) Fix two bugs in select() handling in http_main.c.
8639 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
8640 is unset (as it is in situations like timeouts) where it is unclear
8641 whether errno is set or not. [Martin Kraemer]
8643 *) Just having APACI's localstatedir is too general and not enough for most
8644 of the systems. 1.3b6 again required manual APACI patches by package
8645 maintainers from Red Hat and FreeBSD because for their filesystem layout a
8646 little bit more flexibility in configuring the paths is needed. Hence we
8647 provide three additional configure options (--runtimedir, --logfiledir,
8648 --proxycachedir) which now can be used for more granular adjustments if
8649 --localstatedir is not enough to fit the particular needs. As a nice
8650 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
8651 [Ralf S. Engelschall]
8653 *) Make the install root for "make install" in APACI's Makefile overrideable
8654 by package authors. This way we are even more friendly to package
8655 maintainers (especially Debian and Red Hat) who build for the real prefix
8656 via "configure --prefix=/<real>" but use a different local prefix via
8657 "make root=/tmp/apache install" for rolling the package without bristling
8658 the target location on their system.
8659 [Ralf S. Engelschall]
8661 *) Workaround sed limitations in APACI's configure script by now
8662 substituting in chunks of 50 commands (because for instance HPUX's vendor
8663 sed has a limit of max. 98 commands)
8664 [Ralf S. Engelschall] PR#2136
8666 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
8667 [Ralf S. Engelschall] PR#2140
8669 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
8670 RENAMING process because they are defined as pre-processor macros instead
8671 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
8672 [Ralf S. Engelschall]
8674 *) Workaround braindead AWK's when generating ap_config.h: The split() and
8675 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
8676 [Ralf S. Engelschall] PR#2139
8678 *) Various bugfixes and cleanups for the APACI configure script:
8679 o fix IFS handling for _nested_ situation
8680 o fix Perl interpreter search: take first one found instead of last one
8681 o fix DSO consistency check
8682 o print error messages to stderr instead of stdout
8683 o add install-quiet for --shadow situation to Makefile stub
8684 o reduce complexity by avoiding sed-hacks for rule and module list loops
8685 [Ralf S. Engelschall]
8687 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
8689 *) Make sure the input field separator (IFS) shell variable is explicitly
8690 initialized correctly before _every_ `for' loop and also restored after
8691 the loops. [Ralf S. Engelschall]
8693 *) Make sure that "make install" doesn't overwrite the `mime.types' and
8694 `magic' files from an existing Apache installation. Because people often
8695 customize these for own MIME and content types.
8696 [Ralf S. Engelschall]
8698 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
8699 [Peter Galbavy, Ralf S. Engelschall] PR#2109
8701 *) Fix the path to the ScoreBoardFile in the install-config target, too.
8702 [Ralf S. Engelschall] PR#2105
8704 *) Let "configure" clear out the users parameters (provided as shell
8705 variables) to avoid side-effects in "src/Configure" when the user
8706 exported them (which is not needed, but some users do it).
8707 [Ralf S. Engelschall] PR#2101
8709 *) Provide backward compatibility from some old src/Configuration.tmpl
8710 parameter names to the canonical Autoconf-style shell variable names. For
8711 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
8712 but a hint message is displayed. [Ralf S. Engelschall]
8714 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
8715 CGI scripts from an existing Apache installation.
8716 [Ralf S. Engelschall, Jim Jagielski] PR#2084
8718 *) Make `configure --compat' more "compatible" by first
8719 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
8720 second by making sure the "avoid-bristling-suffix" /apache is not
8721 appended to sysconfdir, datadir, localstatedir and includedir when
8722 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
8724 *) NeXT required strdup() in support/logresolve.c

8730 *) Fix the path to the MimeMagicFile in the install-config target, too.
8731 [Ralf S. Engelschall] PR#2089
8733 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
8735 *) If you start apache with the -S command line option it will dump
8736 out the parsed vhost settings. This is useful for folks trying
8737 to figure out what is wrong with their vhost configuration.
8738 (Other dumps may be added in the future.) [Dean Gaudet]
8740 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
8741 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
8744 *) Because /usr/local/apache is the default prefix the ``configure
8745 --compat'' option no longer has to set prefix, again. This way the
8746 --compat option honors a leading --prefix option. [Lars Eilebrecht]
8748 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
8749 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
8750 to avoid "discard const" warnings. [Ralf S. Engelschall]
8752 *) If a specific handler is set for a file yet the request still
8753 ends up being handled by the default handler, log an error
8754 message before handling it. This catches things such as trying
8755 to use SSIs without mod_include enabled. [Marc Slemko]
8757 *) Fix error logging for the startup case where ap_log_error() still uses
8758 stderr as the target. Now the default log level is honored here, too.
8759 [Ralf S. Engelschall]
8761 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
8762 long" errors when generating the MODULES entry for src/Makefile
8763 [Ben Hyde, Ralf S. Engelschall]
8765 *) Make sure src/Configure doesn't complain about the old directory
8766 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
8768 Changes with Apache 1.3b6
8770 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
8772 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
8773 interface via the similar but proprietary HP/UX shl_xxx-style system
8774 calls. [Ralf S. Engelschall]
8776 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
8777 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
8778 Make. [Ralf S. Engelschall]
8780 *) ++++ THE BIG SYMBOL RENAMING ++++
8781 To avoid symbol clashes with third-party code compiled into the server,
8782 we globally applied the prefix "ap_" to the following classes of
8784 - Apache provided general functions (e.g., ap_cpystrn)
8785 - Public API functions (e.g., palloc, bgets)
8786 - Private functions which we can't make static (because of
8787 cross-object usage) but should be (e.g., new_connection)
8788 For backward source compatibility a new header file named compat.h was
8789 created which provides defines for the old symbol names and can be used
8790 by third-party module authors.
8793 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
8794 problem under SVR4 is that there is no command flag to force the linker
8795 to export the global symbols of the httpd executable therewith they are
8796 available to the DSO's. Instead of problematic hacks like creating a
8797 dummy.so file (containing dummy references to all global symbols) the
8798 httpd binary is linked against, we use a clean trick stolen from Perl 5:
8799 Placing the Apache core code itself into a DSO library named libhttpd.so.
8800 This way the global symbols _HAVE_ to be exported and thus are available
8801 to any manually loaded DSO's under runtime. To reduce the impact to the
8802 user to null we go even further and create a stub httpd executable which
8803 automatically keeps track of the DSO library loading itself and thus
8804 hides the complete mechanism from the user. Although the generation of
8805 this DSO library is automatically triggered for platforms which
8806 essentially need it (mostly all SVR4-derivates) it can be also enabled
8807 manually via the Rule SHARED_CORE. This can be interesting in the future
8808 where we perhaps exploit this libhttpd.so mechanism for providing nifty
8809 features like graceful upgrades, or whatever.
8810 [Ralf S. Engelschall, Martin Kraemer]
8812 *) Build the libraries before building the rest of the tools. [Ben Hyde]
8814 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
8815 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
8816 conventions while "clean" removes only stuff created by "all" targets,
8817 "distclean" additionally removes the stuff from the configuration
8818 process. This way "make distclean" (hence the name) provides a fresh
8819 source tree as it was for distribution.
8820 [Ralf S. Engelschall]
8822 *) Allow top-level (APACI) Makefile to break on build errors
8823 the same way the src/ subtree Makefiles breaks on them by replacing the
8824 initial APACI sed-subdir-display-kludge with a more clean
8825 variable-passing-solution: variable SDP can optionally hold the subdir
8826 prefix which is consistently used for displaying the subdir movement.
8827 This way even the top-level Makefile can stop correctly on errors as the
8828 user expects. [Ralf S. Engelschall]
8830 *) Fixed ordering of argument checks for RewriteBase directive.
8831 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
8833 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
8834 indicating that a module is being compiled for dynamic loading. Also
8835 remove #define IS_MODULE from modules and add SHARED_MODULE define
8836 to the mak/dsp files. [Alexei Kosut]
8838 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
8839 since we are now logging APLOG_WARNING by default. [Roy Fielding]
8841 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
8843 *) Add documentation file and src/Configuration.tmpl entry for the
8844 experimental mod_mmap_static module. Because although it is and marked as
8845 an experimental one it is distributed and thus should be documented and
8846 prepared for configuration the same way as all others modules.
8847 [Ralf S. Engelschall]
8849 *) Add query (-q) option to apxs support tool to be able to manually query
8850 specific settings from apxs. This is needed for instance when you
8851 manually want to access Apache's header files and you need to assemble
8852 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
8853 [Ralf S. Engelschall]
8855 *) Now src/Configure uses a fallback strategy for the shared object support
8856 on platforms where no explicit information is available: If a Perl
8857 installation exists we ask it about its shared object support and if it's
8858 the dlopen-style one we shamelessly guess the compiler and linker flags
8859 for creating shared objects from Perls knowledge. Of course, the user is
8860 warning about what we are doing and informed that he should send us
8861 the guessed flags when they work. [Ralf S. Engelschall]
8863 *) Provide APACI --without-support option to be able to disable the build
8864 and installation of the support tools from the src/support/ area.
8865 Although its useful to have these installed per default we should provide
8866 a way to compile and install without them for backward-compatibility.
8867 [Ralf S. Engelschall]
8869 *) Add of the new APache eXtenSion (apxs) support tool for building and
8870 installing modules into an _already installed_ Apache package through the
8871 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
8872 this approach actually doesn't need the Apache source tree. The
8873 (APACI-installed) server package is enough, because this now includes the
8874 Apache C header files (PREFIX/include) and the new APXS tool
8875 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
8876 module authors to build their Apache modules _OUTSIDE_ the Apache source
8877 tree while avoiding them to fiddle around with the totally platform
8878 dependend way of compiling DSO files. The tool supports all ranges of
8879 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
8880 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
8881 on-the-fly generate a minimalistic Makefile and sample module for the
8882 first step to provide both a quick success event and to demonstrate the
8883 APXS mechanism to module authors. [Ralf S. Engelschall]
8885 *) Fix core dumps in use of CONNECT in proxy.
8886 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
8888 *) Modify the log directives in httpd.conf-dist files to use CustomLog
8889 so that users have examples of how CustomLog can be used.
8892 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
8893 the Apache distribution tree. Until Apache 1.3 there was no real
8894 out-of-the-box batch-capable build and installation procedure for the
8895 complete Apache package. This is now provided by a top-level "configure"
8896 script and a corresponding top-level "Makefile.tmpl" file. The goal is
8897 to provide a GNU Autoconf-style frontend which is capable to both drive
8898 the old src/Configure stuff in batch and additionally installs the
8899 package with a GNU-conforming directory layout. Any options from the old
8900 configuration scheme are available plus a lot of new options for flexibly
8901 customizing Apache. [Ralf S. Engelschall]
8903 *) The floating point ap_snprintf code wasn't threadsafe.
8904 Had to remove the HAVE_CVT macro in order to do threadsafe
8905 calling of the ?cvt() floating point routines. [Dean Gaudet]
8907 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
8909 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
8910 [Jim Jagielski] PR#1901
8912 *) BUG: Configure was using TCC and CC inconsistently. Make sure
8913 Configure knows which CC we are using. [Jim Jagielski]
8915 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
8916 was defined in a parent directory. [Lars Eilebrecht]
8918 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
8919 a generic printf-style routine that can call arbitrary output
8920 routines. Use this to replace http_bprintf.c. Add new routines
8921 psprintf(), pvsprintf() which allocate the exact amount of memory
8922 required for a string from a pool. Use psprintf() to clean up
8923 various bits of code which used ap_snprintf()/pstrdup().
8926 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
8927 ap_snprintf() has different semantics and formatting codes than
8928 snprintf(). [Dean Gaudet]
8930 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
8931 is necessary on at least Solaris where the /etc/rc?.d scripts
8932 are run with these signals ignored, and "SIG_IGN" settings are
8933 maintained across exec().
8934 [Rein Tollevik <reint@sys.sol.no>] PR#2009
8936 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
8937 used instead of lstat() and thus this flag didn't work as expected.
8938 [Rein Tollevik <reint@sys.sol.no>] PR#2010
8940 *) Fix the proxy pass-through feature of mod_rewrite for the case of
8941 existing QUERY_STRING now that mod_proxy was recently changed because of
8942 the new URL parsing stuff. [Ralf S. Engelschall]
8944 *) A few changes to scoreboard definitions which helps gcc generate
8945 better code. [Dean Gaudet]
8947 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
8948 be a signed bitfield. So mark a few bitfields as signed to
8949 ensure correct code. [Dean Gaudet]
8951 *) The default for HostnameLookups was changed to Off, but there
8952 was a problem and it wasn't taking effect. [Dean Gaudet]
8954 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
8957 *) After a SIGHUP the listening sockets in the parent weren't
8958 properly marked for closure on fork().
8959 [Jürgen Keil <jk@tools.de>] PR#2000
8961 *) Allow %2F in two situations: 1) it is in the query part of the URI,
8962 therefore not exposed to %2F -> '/' translations and 2) the request
8963 is a proxy request, so we're not dealing with a local resource anyway.
8964 Without this, the proxy would fail to work for any URL's with
8965 %2f in them (occurs quite often in
8966 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
8968 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
8970 *) Make the shared object compilation command more portable by avoiding
8971 the direct combination of `-c' & `-o' which is not honored by some
8972 compilers like UnixWare's cc. [Ralf S. Engelschall]
8974 *) WIN32: the proxy was creating filenames missing the last four
8975 characters. While this normally doesn't stop anything from
8976 working, it can result in extra collisions.
8977 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
8979 *) Now mod_proxy uses the response string (in addition to the response status
8980 code) from the already used FTP SIZE command to setup the Content-Length
8981 header if available. [Ralf S. Engelschall] PR#1183
8983 *) Reanimated the (still undocumented) proxy receive buffer size directive:
8984 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
8985 name was really too generic, added documentation for this directive to
8986 the mod_proxy.html and corrected the hyperlink to it in the
8987 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
8989 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
8990 faster [Martin Kraemer]
8992 *) Make Configure die when you give it an unknown command switch.
8995 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
8996 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
8997 and per default compiled support programs have manual pages - just to
8998 document our stuff a little bit more and to be able to do really
8999 Unix-like installations ;-) [Ralf S. Engelschall]
9001 *) Major cleanups to the Configure script to make it and its generated
9002 Makefiles again readable and maintainable: add SRCDIR option, removed
9003 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
9004 generated sections, consequently added Makefile headers with inheritance
9005 information, added subdir movement messages for easier following where
9006 the build process currently stays (more verbose then standard Make, less
9007 verbose than GNU make), same style to comments in the Configure script,
9008 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
9010 *) Add the new ApacheBench program "ab" to src/support/: This is derived
9011 from the ZeusBench benchmarking program and can be used to determine the
9012 response performance of an Apache installation. This version is
9013 officially licensed with Zeus Technology, Ltd. See the license agreement
9014 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
9015 [Ralf S. Engelschall]
9017 *) API: Various core functions that are definately not part of the API
9018 have been made static, and a few have been marked API_EXPORT. Still
9019 more have been marked CORE_EXPORT and are not intended for general
9020 use by modules. [Doug MacEachern, Dean Gaudet]
9022 *) mod_proxy was not clearing the Proxy-Connection header from
9023 requests; now it does. This did not violate any spec, however
9024 causes poor interactions when you are talking to remote proxies.
9025 [Marc Slemko] PR#1741
9027 *) Various cleanups to the command line interface and manual pages.
9028 [Ralf S. Engelschall]
9030 *) cfg_getline() was not properly handling lines that did not end
9031 with a line termination character. [Marc Slemko] PR#1869, 1909
9033 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
9035 *) Clean up some undocumented behavior of mod_setenvif related to
9036 "merging" two SetEnvIf directives when they match the same header
9037 and regex. Document that mod_setenvif will perform comparisons in
9038 the order they appear in the config file. Optimize mod_setenvif by
9039 doing more work at config time rather than at runtime.
9042 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
9043 to allow for modules to overrule them and to reduce redefinition
9044 warnings [Jim Jagielski]
9046 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
9049 *) Making the hard-coded cross-module function call mime_find_ct() (from
9050 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
9051 checking is really called even for proxy requests except for URLs with
9052 HTTP schemes (because there we can optimize by not running the type
9053 checking hooks due to the fact that the proxy gets the MIME Content-type
9054 from the remote host later). This change cleans up mod_mime by removing
9055 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
9056 especially unbundles mod_proxy and mod_mime. This way they both now can
9057 be compiled as shared objects and are no longer tied together.
9058 [Ralf S. Engelschall]
9060 *) util.c cleanup and speedup. [Dean Gaudet]
9062 *) API: Clarification, pstrndup() will always copy n bytes of the source
9063 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
9065 *) Mark module command_rec and handler_rec structures const so that they
9066 end up in the read-only data section (and are friendlier to systems
9067 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
9069 *) Add check to the "Port" directive to make sure the specified
9070 port is in the appropriate range. [Ben Hyde]
9072 *) Performance improvements to invoke_handler().
9073 [Dmitry Khrustalev <dima@bog.msu.su>]
9075 *) Added support for building shared objects even for library-style modules
9076 (which are built from more than one object file). This now provides the
9077 ability to build mod_proxy as a shared object module. Additionally
9078 modules like mod_example are now also supported for shared object
9079 building because the generated Makefiles now no longer assume there is at
9080 least one statically linked module. [Ralf S. Engelschall]
9082 *) API: Clarify usage of content_type, handler, content_encoding,
9083 content_language and content_languages fields in request_rec. They
9084 must always be lowercased; and the strings pointed to shouldn't
9085 be modified (you must copy them to modify them). Fix a few bugs
9086 related to this. [Dean Gaudet]
9088 *) API: Clarification: except for RAW_ARGS, all command handlers can
9089 treat the char * parameters as permanent, and modifiable. There
9090 is no need to pstrdup() them. Clean up some needless pstrdup().
9093 *) Now mod_so keeps track of which module shared objects with which names
9094 are loaded and thus avoids multiple loading and unloading and irritating
9095 error_log messages. [Ralf S. Engelschall]
9097 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
9098 environment variable in the apache core. But that tweaking interferes
9099 with mod_setenv. So don't tweak if the user has specified an explicit
9100 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
9102 *) rputs() did not calculate r->sent_bodyct properly.
9103 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
9105 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
9106 name, or left unset if this value is unavailable. Apache was setting
9107 it to the IP address when unavailable.
9108 [Tony Finch <fanf@demon.net>] PR#1925
9110 *) Various improvements to the configuration and build support for compiling
9111 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
9112 OSF1 support with GCC and vendor compilers was added. This way shared
9113 object support is now provided out-of-the-box for FreeBSD, Linux,
9114 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
9115 [Ralf S. Engelschall]
9117 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
9118 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
9119 and USE_OS2_SCOREBOARD. [Dean Gaudet]
9121 *) Fix one more special locking problem for RewriteMap programs in
9122 mod_rewrite: According to the documentation of flock(), "Locks are on
9123 files, not file descriptors. That is, file descriptors duplicated
9124 through dup(2) or fork(2) do not result in multiple instances of a lock,
9125 but rather multiple references to a single lock. If a process holding a
9126 lock on a file forks and the child explicitly unlocks the file, the
9127 parent will lose its lock.". To overcome this we have to make sure the
9128 RewriteLock file is opened _AFTER_ the childs were spawned which is now
9129 the case by opening it in the child_init instead of the module_init API
9130 hook. [Ralf S. Engelschall] PR#1029
9132 *) Change to Location and LocationMatch semantics. LocationMatch no
9133 longer lets a single slash match multiple adjacent slashes in the
9134 URL. This change is for consistency with RewriteRule and
9135 AliasMatch. Multiple slashes have meaning in URLs that they do
9136 not have in (some) filesystems. Location on the other hand can
9137 be considered a shorthand for a more complicated regex, and it
9138 does match multiple slashes with a single slash -- which is
9139 also consistent with the Alias directive.

9142 *) Fix bug with mod_mime_magic causing certain files, including files
9143 of length 0, to result in no response from the server.
9146 *) The Configure script now generates src/include/ap_config.h which
9147 contains the set of defines used when Apache is compiled on a platform.
9148 This file can then be included by external modules before including
9149 any Apache header files in case they are being built separately from
9150 Apache. Along with this change, a couple of minor changes were
9151 made to make Apache's #defines coexist peacefully with any autoconf
9152 defines an external module might have. [Rasmus Lerdorf]
9154 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9155 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9156 chance by the API to initialize its per-server configuration and thus
9157 receives the wrong one from the main server. This is now avoided by
9158 remembering the server together with the config structure while
9159 configuring and later assuming there is no config when we see a
9160 difference between the remembered server and the one calling us.
9161 [Ralf S. Engelschall] PR#1790
9163 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9164 is automatically disabled under configure time when the dbm_xxx functions
9165 are not available. Second, two heavy source code errors in the DBM
9166 support code were fixed. This makes DBM RewriteMap's usable again after
9167 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9169 *) Now all configuration files support Unix-style line-continuation via
9170 the trailing backslash ("\") character. This enables us to write down
9171 complex or just very long directives in a more readable way. The

9189 depending on the rev of Solaris and what mixture of modules
9190 are in use. So it has been disabled, and Solaris is back to
9191 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9192 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9193 up static content only servers. Or it may fail unpredictably.
9194 [Dean Gaudet] PR#1779, 1854, 1904
9196 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9199 *) API: Rewrite of absoluteURI handling, and in particular how
9200 absoluteURIs match vhosts. Unless a request is a proxy request, a
9201 "http://host" url is treated as if a similar "Host:" header had been
9202 supplied. This change was made to support future HTTP/1.x protocols
9203 which may require clients to send absoluteURIs for all requests.
9205 In order to achieve this change subtle changes were made to the API. In a
9206 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9207 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9208 by the core, modules must set it during the post_read_request or
9209 translate_names phase.
9211 Plus changes to the virtualhost test suite for absoluteURI testing.
9213 This fixes several bugs with the proxy proxying requests to vhosts
9214 managed by the same httpd.
9217 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
9218 code from mod_rewrite. The vhost matching is now performed by a
9219 globally available function matches_request_vhost(). [Dean Gaudet]

9235 *) API: A new source module main/util_uri.c; It contains a routine
9236 parse_uri_components() and friends which breaks a URI into its component
9237 parts. These parts are stored in a uri_components structure called
9238 parsed_uri within each request_rec, and are available to all modules.
9239 Additionally, an unparse routine is supplied which re-assembles the URI
9240 components back to an URI, optionally hiding the username:password@ part
9241 from ftp proxy requests, and other useful routines. Within the structure,
9242 you find on a ready-for-use basis:
9243 scheme; /* scheme ("http"/"ftp"/...) */
9244 hostinfo; /* combined [user[:password]@]host[:port] */
9245 user; /* user name, as in http://user:passwd@host:port/ */
9246 password; /* password, as in http://user:passwd@host:port/ */
9247 hostname; /* hostname from URI (or from Host: header) */
9248 port_str; /* port string (integer representation is in "port") */
9249 path; /* the request path (or "/" if only scheme://host was given) */
9250 query; /* Everything after a '?' in the path, if present */
9251 fragment; /* Trailing "#fragment" string, if present */
9252 This is meant to serve as the platform for *BIG* savings in
9253 code complexity for the proxy module (and maybe the vhost logic).
9256 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
9257 ${map:key}) available for all location where a string is created in
9258 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
9259 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
9260 possible expansions are consequently usable at all string creation
9261 locations. [Ralf S. Engelschall]
9263 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
9264 and not 1) and the per-virtual-server merging of directives. Now all
9265 directives except `RewriteEngine' and `RewriteOption' are either
9266 completely overridden (default) or completely inherited (when
9267 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

9276 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
9277 (like SunOS and FreeBSD) which don't accept the locking of pipes

9279 setup a separate locking file which then is used for synchronization.

9297 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
9298 type but with a special post-processing for the looked-up value: It
9299 parses it into alternatives according to `|' chars and then only one
9300 particular alternative is chosen randomly (this is an essential
9301 functionality needed for balancing between backend-servers when using
9302 Apache as a Reverse Proxy. The looked up value here is a list of
9303 servers). Second, `int' with the built-in maps named `tolower' and
9304 `toupper' which can be used to map URL parts to a fixed case (this is an
9305 essential feature to fix the case of server names when doing mass
9306 virtual-hosting with the help of mod_rewrite instead of using
9307 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from

9310 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
9311 This directive lets Apache adjust the URL in Location-headers on HTTP
9312 redirect responses sent by the remote server. This way the virtually
9313 mapped area is no longer left on redirects and thus by-passed which is
9314 especially essential when running Apache as a reverse proxy.

9429 now ignores a leading x- when comparing encodings. It also
9430 preserves the encoding the client requests (for example if

9462 *) Yet another rearrangement of the source tree.. now all the common
9463 header files are in the src/include directory. The -Imain -Iap
9464 references in Makefiles have been changed to the simpler -Iinclude
9465 instead. In addition to simplifying the build a little bit, this
9466 also makes it clear when a module is referencing something in a
9467 other than kosher manner (e.g., the proxy including mod_mime.h).
9468 Module-private header files (the proxy, mod_mime, the regex library,
9469 and mod_rewrite) have not been moved to src/include; nor have
9470 the OS-abstraction files. [Ken Coar]

9482 server setting inside vhosts (only an issue when you have no
9483 <Directory> or other section containing an Options that affects
9484 a request). Options +foo or -foo in the main_server wouldn't

9499 *) mod_unique_id was erroneously generating a second unique id when
9500 an internal redirect occured. Such redirects occur, for example,
9501 when processing a DirectoryIndex match. [Dean Gaudet]
9503 *) API: table_add, table_merge, and table_set include implicit pstrdup()
9504 of the key and value. But in many cases this is not required
9505 because the key/value is a constant, or the value has been built
9506 by pstrcat() or other similar means. New routines table_addn,
9507 table_mergen, and table_setn have been added to the API, these
9508 routines do not pstrdup() their arguments. The core code and
9509 standard modules were changed to take advantage of these routines.
9510 The resulting server is up to 20% faster in some situations.
9512 Note that it is easy to get code subtly wrong if you pass a key/value
9513 which is in a pool other than the pool of the table. The only
9514 safe thing to do is to pass key/values which are in the pool of
9515 the table, or in one of the ancestors of the pool of the table.
9516 i.e. if the table is part of a subrequest, a value from the main
9517 request's pool is OK since the subrequest pool is a sub_pool of the
9518 main request's pool (and therefore has a lifespan at most as long as
9519 the main pool). There is debugging code which can detect improper
9520 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
9521 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
9523 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
9524 which don't exist on disk more gracefully; handles vhosts properly.
9525 Update documentation to reflect the code -- if there's no
9526 MimeMagicFile directive then the module is not enabled.
9529 *) PORT: Some older *nix dialects cannot automatically start scripts
9530 which begin with a #! interpreter line (the shell starts the scripts
9531 appropriately on these platforms). Apache now supports starting of
9532 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.

9536 *) API: "typedef array_header table" removed from alloc.h, folks should
9537 have been writing to use table as if it were an opaque type, but even
9538 some standard modules got this wrong. By changing the definition
9539 to "typedef struct table table" module authors will receive compile
9540 time warnings that they're doing the wrong thing. This change
9541 facilitates future changes with more sophisticated table
9542 structures. Specifically, module authors should be using table_elts()
9543 to get access to an array_header * for the table. [Dean Gaudet]
9545 *) API: Renamed new_connection() to avoid namespace collision with LDAP
9546 library routines. [Ken Coar, Rasmus Lerdorf]
9548 *) WIN32: mod_speling is now available on the Win32 platform.
9551 *) For clarity the following compile time definition was changed:
9553 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
9555 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
9556 and not be a general notice that the OS has mmap(). Now the
9557 HAVE_MMAP/SHMGET #defines strictly are informational that the
9558 OS has that method of shared memory; the type to use for
9559 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
9560 and USE_SHMGET_SCOREBOARD). This allows outside modules to
9561 determine if shared memory is available and allows Apache
9562 to determine the best method to use for the scoreboard.

9699 *) SECURITY: Numerous changes to mod_imap in a general cleanup
9700 including fixing a possible buffer overflow. [Dean Gaudet]
9702 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
9703 (connections are not dropped). Code can handle graceful restarts
9704 (but there is as yet no way to signal this to Apache). Various
9705 other cleanups. [Paul Sutton]
9707 *) The aplog_error changes specific to 1.3 introduced a buffer
9708 overrun in the (now legacy) log_printf function. Fixed.
9711 *) mod_digest didn't properly deal with proxy authentication. It
9712 also lacked a case-insensitive comparision of the "Digest"
9713 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
9715 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
9717 *) A few cleanups in mod_info to make it thread-safe, and remove an
9718 off-by-5 bug that could hammer \0 on the stack. [Dean Gaudet]
9720 *) no2slash() was O(n^2) in the length of the input. Make it O(n).
9723 *) API: migration from strncpy() to our "enhanced" version called
9724 ap_cpystrn() for performance and functionality reasons.
9725 Located in libap.a. [Jim Jagielski]
9727 *) table_set() and table_unset() did not deal correctly with
9728 multiple occurrences of the same key.
9729 [Stephen Scheck <sscheck@infonex.net>, Ben Laurie] PR#1604
9731 *) The AuthName must now be enclosed in quotes if it is to contain
9732 spaces. [Ken Coar] PR#1195
9734 *) API: new function: ap_escape_quotes(). [Ken Coar] PR#1195
9736 *) WIN32: Work around optimiser bug that killed ISAPI in release
9737 versions. [Ben Laurie] PR#1533
9739 *) PORT: Update the MPE port [Mark Bixby, Jim Jagielski]
9741 *) Interim (slow) fix for p->sub_pool critical sections in
9742 alloc.c (affects win32 only). [Ben Hyde]
9744 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
9746 *) send_fd_length() did not calculate total_bytes_sent properly.
9747 [Ben Reser <breser@regnow.com>] PR#1366
9749 *) The bputc() macro was not properly integrated with the chunking
9750 code; in many cases modules using bputc() could cause completely
9751 bogus chunked output. (Typically this will show up as problems
9752 with Internet Explorer 4.0 reading a page, but other browsers
9753 having no problem.) [Dean Gaudet]
9755 *) Create LARGE_WRITE_THRESHOLD define which determines how many
9756 bytes have to be supplied to bwrite() before it will consider
9757 doing a writev() to assemble multiple buffers in one system
9758 call. This is critical for modules such as mod_include,
9759 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
9760 strings in some cases. The result would be extra effort
9761 setting up writev(), and in many cases extra effort building
9762 chunks. The default is 31, it can be overriden at compile
9765 *) Move the gid switching code into the child so that log files
9766 and pid files are opened with the root gid.
9767 [Gregory A Lundberg <lundberg@vr.net>]
9769 *) WIN32: Check for binaries by looking for the executable header
9770 instead of counting control characters.
9771 [Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340
9773 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
9774 so the functionality is available to applications other than the
9775 server itself (like the src/support tools). [Ken Coar]
9777 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
9778 the libap consolidation work. [Ken Coar]
9780 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
9781 useful, and isn't what the standards require. Now it returns 0
9782 and writes nothing. [Dean Gaudet]
9784 *) When an error occurs in fcntl() locking suggest the user look up
9785 the docs for LockFile. [Dean Gaudet]
9787 *) Eliminate some dead code from writev_it_all().
9788 [Igor Tatarinov <tatarino@prairie.NoDak.edu>]
9790 *) mod_autoindex had an fread() without checking the result code.
9791 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"
9792 (note the missing closing paren) properly. [Dean Gaudet]
9794 *) It appears the "257th byte" bug (see
9795 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
9796 at the 256th byte as well. Fixed. [Dean Gaudet]
9798 *) PORT: Fix mod_mime_magic under OS/2, no support for block devices.
9801 *) Fix memory corruption caused by allocating auth usernames in the
9802 wrong pool. [Dean Gaudet] PR#1500
9804 *) Fix an off-by-1, and an unterminated string error in
9805 mod_mime_magic. [Dean Gaudet]
9807 *) Fix a potential SEGV problem in mod_negotiation when dealing
9808 with type-maps. [Dean Gaudet]
9810 *) Better glibc support under Linux. [Dean Gaudet] PR#1542
9812 *) "RedirectMatch gone /" would cause a SIGSEGV. [Dean Gaudet] PR#1319
9814 *) WIN32: avoid overflows during file canonicalisations.
9815 [malcolm@mgdev.demon.co.uk] PR#1378
9817 *) WIN32: set_file_slot() didn't detect absolute paths. [Ben Laurie]
9820 *) WIN32: mod_status display header didn't match fields. [Ben Laurie]
9822 *) The pthread_mutex_* functions return an error code, and don't
9823 set errno. [Igor Tatarinov <tatarino@prairie.NoDak.edu>]
9825 *) WIN32: Allow spaces to prefix the interpreter in #! lines.
9826 [Ben Laurie] PR#1101
9828 *) WIN32: Cure file leak in CGIs. [Peter Tillemans <pti@net4all.be>] PR#1523
9830 *) proxy_ftp: the directory listings generated by the proxy ftp module
9831 now have a title in which the path components are clickable and allow
9832 quick navigation to the clicked-on directory on the currently listed
9833 ftp server. This also fixes a bug where the ".." directory links would
9834 sometimes refer to the wrong directory. [Martin Kraemer]
9836 *) WIN32: Allocate the correct amount of memory for the scoreboard.
9839 *) WIN32: Only lowercase the part of the path that is real. [Ben Laurie]
9842 *) Fix problems with timeouts in inetd mode and -X mode. [Dean Gaudet]
9844 *) Fix the spurious "(0)unknown error: mmap_handler: mmap failed"
9845 error messages. [Ben Hyde]
9847 Changes with Apache 1.3b3
9849 *) WIN32: Work around brain-damaged spawn calls that can't deal
9850 with spaces and slashes. [Ben Laurie]
9852 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
9853 The problem was that certain undocumented environment variables
9854 needed for sockets to work under Win32 were not being passed.
9855 [Frank Faubert <frank@sane.com>]
9857 *) Add a "-V" command line flag to the httpd binary. This
9858 flag shows some of the defines that Apache was compiled with.
9859 It is useful for debugging purposes. [Martin Kraemer]
9861 *) Start separating the ap_*() routines into their own library, so they
9862 can be used by items in src/support among other things.
9863 [Ken Coar] PR#512, 905, 1252, 1308
9865 *) Give a more informative error when no AuthType is set.
9868 *) Remove strtoul() use from mod_proxy because it isn't available
9869 on all platforms. [Marc Slemko] PR#1214
9871 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
9872 This turns out to be a bug in Winsock - select() doesn't always
9873 return the correct status. [Ben Laurie]
9875 *) Directives owned by http_core can now use the new check_cmd_context()
9876 routine to ensure that they're not being used within a container
9877 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
9879 *) PORT: Recent changes made it necessary to add explicit prototype
9880 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
9882 *) It was necessary to distinguish between resources which are
9883 allocated in the parent, for cleanup in the parent, and resources
9884 which are allocated in each child, for cleanup in each child.
9885 A new pool was created which is passed to the module child_init
9886 and child_exit functions; modules are free to register per-child
9887 cleanups there. This fixes a bug with reliable piped logs.
9890 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
9891 unless it was also doing FancyIndexes, but it displayed the
9892 HeaderName file at the top under all circumstances. It now shows
9893 the ReadmeName file for simple indices, too, as it should.
9896 *) http_core was mmap()ing even in cases where it wasn't going to
9897 read the file. [Ben Hyde <bhyde@gensym.com>]
9899 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
9900 Now the rewriting engine (the heart of mod_rewrite) is organized more
9901 straight-forward, first time well documented and reduced to the really
9902 essential parts. All redundant cases were stripped off and processing now
9903 is the same for both per-server and per-directory context with only a
9904 minimum difference (the prefix stripping in per-dir context). As a
9905 side-effect some subtle restrictions and two recently discovered problems
9906 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
9907 context and restrictions on the substitution URL on redirects.
9908 Additionally some minor source cleanups were done.
9909 [Ralf S. Engelschall]
9911 *) Lars Eilebrecht wrote a whole new set of Apache Vhost Internals
9912 documentation, examples, explanations and caveats. They live in a new
9913 subdirectory htdocs/manual/vhost/. [Lars Eilebrecht <sfx@unix-ag.org>]
9915 *) If ap_slack fails to allocate above the low slack line it's a good
9916 indication that further problems will occur; it's a better indication
9917 than many external libraries give us when we actually run out of
9918 descriptors. So report it to the user once per restart.

9941 *) Fix a byte ordering problem in mod_access which prevented
9942 the old-style syntax (i.e. "a.b.c." to match a class C)
9943 from working properly. [Dean Gaudet] PR#1248, 1328, 1384

10063 Changes with Apache 1.3b2 (there is no 1.3b1)
10065 *) TestCompile was not passing $LIBS [Dean Gaudet]
10067 *) Makefile.tmpl was not using $CFLAGS in the link phase.
10070 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
10071 rudimentary memory debugger which can be used on live servers with
10072 low impact -- it sets all allocated and freed memory bytes to 0xa5.
10073 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
10074 and free() for each object. This is far more expensive and should
10075 only be used for testing with tools such as Electric Fence and
10076 Purify. See main/alloc.c for more details. [Dean Gaudet]
10078 *) Configure uses a sh trap and didn't set its exitcode properly.
10079 [Dean Gaudet] PR#1159
10081 *) Yet another vhost revamp. Add the NameVirtualHost directive which
10082 explicitly lists the ip:port pairs that are to be used for name-vhosts.
10083 From a given ip:port, regardless what the Host: header is, you can
10084 only reach the vhosts defined on that ip:port. The precedence of
10085 vhosts was reversed to match other precedences in the config --
10086 the earlier vhosts override the later vhosts. All vhost matching was
10087 moved into http_vhost.[ch]. [Dean Gaudet]
10089 *) ap_inline can be used to force inlining. GNUC __attribute__() can
10090 be used for whatever reason is appropriate (i.e. format() warnings
10091 for printf style functions). Both are enabled only with
10092 gcc >= 2.7.x (so that we have fewer support issues with older
10093 versions). [Dean Gaudet]
10095 *) Fix support for Proxy Authentication (we were testing the response
10096 status too early). [Marc Slemko]
10098 *) CoreDumpDirectory directive directs where the core file is

10105 *) When booting, apache will now detach itself from stdin, stdout,
10106 and stderr. stderr will not be detached until after the config
10107 files have been read so you will be able to see initial error
10108 messages. After that all errors are logged in the error_log.
10109 This makes it more convenient to start apache via rsh, ssh,
10110 or crontabs. [Dean Gaudet] PR#523
10112 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10113 Also removed the auto-generated link to www.apache.org that was the
10114 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10116 *) send_fb would not detect aborted connections in some situations.

10122 *) mod_imap should only handle GET methods. [Jay Bloodworth]
10124 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10126 *) mod_autoindex improperly counted &escapes; as more than one
10127 character in the description. It also improperly truncated
10128 descriptions that were exactly the maximum length.
10131 *) RedirectMatch was not properly escaping the result (PR#1155). Also
10132 "RedirectMatch /advertiser/(.*) $1" is now permitted.
10135 *) mod_include now uses symbolic names to check for request success
10136 and return HTTP errors, and correctly handles all types of
10137 redirections (previously it only did temporary redirect correctly).
10138 [Ken Coar, Roy Fielding]
10140 *) mod_userdir was modifying r->finfo in cases where it wasn't setting

10154 *) Fixed error in proxy_util.c when looping through multiple host IP
10155 addresses. [Lars Eilebrecht] PR#974
10157 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10158 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10159 bytes before writing, but it will never split a log entry across a
10160 buffer boundary. [Dean Gaudet]
10162 *) API: the short_score record has been split into two pieces, one which
10163 the parent writes on, and one which the child writes on. As part of
10164 this change the get_scoreboard_info() function was removed, and
10165 scoreboard_image was exported. This change fixes a race condition
10166 in file based scoreboard systems, and speeds up changes involving the
10167 scoreboard in earlier 1.3 development. [Dean Gaudet]
10169 *) API: New register_other_child() API (see http_main.h) which allows
10170 modules to register children with the parent for maintenance. It
10171 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10173 *) API: New piped_log API (see http_log.h) which implements piped logs,
10174 and will use register_other_child to implement reliable piped logs
10175 when it is available. The reliable piped logs part can be disabled
10176 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10177 logs is only available on Unix. [Dean Gaudet]
10179 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10180 meets_conditions(). This allows conditional HTTP selection to be
10181 handled separately from the storing of the header fields, and provides
10182 the ability for CGIs to set their own ETags for conditional checking.
10183 [Ken Coar, Roy Fielding] PR#895

10190 *) New module, "mod_speling", which can help find files even when
10191 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]

10202 Some things (like RewriteMaps) were checked/performed even if they
10203 weren't supposed to be. [Ken Coar] PR #991
10205 *) Implement a new timer scheme which eliminates the need to call alarm() all
10206 the time. Instead a counter in the scoreboard for each child is used to
10207 show when the child has made forward progress. The parent samples this
10208 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10209 progress has been made in the timeout period. This reduces the static
10210 request best-case syscall count to 22 from 29. This scheme is only
10211 used by systems with memory-based scoreboards. [Dean Gaudet]
10213 *) The proxy now properly handles CONNECT requests which are sent
10214 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10216 *) A script called apachectl has been added to the support
10217 directory. This script allows you to do things such as
10218 "apachectl start" and "apachectl restart" from the command
10219 line. [Marc Slemko]
10221 *) Modules and core routines are now put into libraries, which
10222 simplifies the link line tremendously (among other advantages).
10225 *) Some of the MD5 names defined in Apache have been renamed to have
10226 an `ap_' prefix to avoid conflicts with routines supplied by
10227 external libraries. [Ken Coar]
10229 *) Removal of mod_auth_msql.c from the distribution. There are many
10230 other options for databases today. Rather than offer one option,
10231 offer none at this time. mod_auth_msql and other SQL database
10232 authentication modules can be found at the Apache Module Registry.
10233 http://modules.apache.org/ It would be nice to offer a generic
10234 mod_auth_sql option in the near future.
10236 *) PORT: BeOS support added [Alexei Kosut]
10238 *) Configure no longer accepts the -make option, since it creates
10239 Makefile on the fly based on Makefile.tmpl and Configuration.
10241 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
10242 of forcibly killing off all its processes and exiting without
10243 cleaning up. [Alexei Kosut]
10245 *) API: A new field in the request_rec, r->mtime, has been added to
10246 avoid gratuitous parsing of date strings. It is intended to hold
10247 the last-modified date of the resource (if applicable). An
10248 update_mtime() routine has also been added to advance it if
10249 appropriate. [Roy Fielding, Ken Coar]
10251 *) SECURITY: If a htaccess file can not be read due to bad permissions,
10252 deny access to the directory with a HTTP_FORBIDDEN. The previous
10253 behavior was to ignore the htaccess file if it could not be read.
10254 This change may make some setups with unreadable htaccess files
10255 stop working. [Marc Slemko] PR#817
10257 *) Add aplog_error() providing a mechanism to define levels of
10258 verbosity to the server error logging. This addition also provides
10259 the ability to log errors using syslogd. Error logging is configurable
10260 on a per-server basis using the LogLevel directive. Conversion
10261 of log_*() in progress. [Randy Terbush]
10263 *) Further enhance aplog_error() to not log filename, line number, and
10264 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
10266 *) WIN32: Canonicalise filenames under Win32. Short filenames are
10267 converted to long ones. Backslashes are converted to forward
10268 slashes. Case is converted to lower. Parts of URLs that do not
10269 correspond to files are left completely alone. [Ben Laurie]
10271 *) PORT: 2 new OSs added to the list of ports:
10272 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
10273 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
10275 *) Add the server version (SERVER_VERSION macro) to the "server
10276 configured and running" entry in the error_log. Also build an
10277 object file at link-time that contains the current time
10278 (SERVER_BUILT global const char[]), and include that in the
10279 message. [Ken Coar]
10281 *) Set r->headers_out when sending responses from the proxy.
10282 This fixes things such as the logging of headers sent from
10283 the proxy. [Marc Slemko] PR#659
10285 *) support/httpd_monitor is no longer distributed because the
10286 scoreboard should not be file based if at all possible. Use
10287 mod_status to see current server snapshot.
10289 *) (set_file_slot): New function, allowing auth directives to be
10290 independent of the server root, so the server documents can be
10291 moved to a different directory or machine more easily.
10292 [David J. MacKenzie]
10294 *) If no TransferLog is given explicitly, decline
10295 to log. This supports coexistence with other logging modules,
10296 such as the custom one that UUNET uses. [David J. MacKenzie]
10298 *) Check for titles in server-parsed HTML files.
10299 Ignore leading newlines and returns in titles. The old behavior
10300 of replacing a newline after <title> with a space causes the
10301 title to be misaligned in the listing. [David J. MacKenzie]
10303 *) Change mod_cern_meta to be configurable on a per-directory basis.
10304 [David J. MacKenzie]
10306 *) Add 'Include' directive to allow inclusion of configuration
10307 files within configuration files. [Randy Terbush]
10309 *) Proxy errors on connect() are logged to the error_log (nothing
10310 new); now they include the IP address and port that failed
10311 (*that's* new). [Ken Coar, Marc Slemko] PR#352
10313 *) Various architectures now define USE_MMAP_FILES which causes
10314 the server to use mmap() for static files. There are two
10315 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
10316 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
10317 number of bytes written in one cycle from a single mmap()d object,
10318 default 32768). [Dean Gaudet]
10320 *) API: Added post_read_request API phase which is run right after reading
10321 the request from a client, or right after an internal redirect. It is
10322 useful for modules setting environment variables that depend only on
10323 the headers/contents of the request. It does not run during subrequests
10324 because subrequests inherit pretty much everything from the main
10325 request. [Dean Gaudet]
10327 *) Added mod_unique_id which is used to generate a unique identifier for
10328 each hit, available in the environment variable UNIQUE_ID.
10331 *) init_modules is now called after the error logs have been opened. This
10332 allows modules to emit information messages into the error logs.
10335 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10336 information for case where proxy module is not available. [Marc Slemko]
10338 *) PORT: Apache has need for mutexes to serialize its children around
10339 accept. In prior versions either fcntl file locking or flock file
10340 locking were used. The method is chosen by the definition of
10341 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
10342 and FLOCK for flock(). New options have been added:
10343 - SYSVSEM to use System V style semaphores
10344 - PTHREAD to use POSIX threads (appears to work on Solaris only)
10345 - USLOCK to use IRIX uslock
10346 Based on timing various techniques, the following changes were made
10348 - Linux 2.x uses flock instead of fcntl
10349 - Solaris 2.x uses pthreads
10350 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
10351 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
10352 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
10353 Martijn Koster <m.koster@pobox.com>]
10355 *) PORT: The semantics of accept/select make it very desirable to use
10356 mutexes to serialize accept when multiple Listens are in use. But
10357 in the case where only a single socket is open it is sometimes
10358 redundant to serialize accept(). Not all unixes do a good job with
10359 potentially dozens of children blocked on accept() on the same
10360 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
10361 the server will avoid serialization when listening on only one socket,
10362 and use serialization when listening on multiple sockets.
10363 [Dean Gaudet] PR#467
10365 *) Configure changes: TestLib replaced by TestCompile, which has
10366 some additional capability (such as doing a sanity check of
10367 the compiler and flags selected); the version of Solaris is now
10368 available via the #define value of SOLARIS2; IRIX n32bit libs
10369 now supported and selectable by new Configuration Rule: IRIXN32;
10370 We no longer default to -O2 optimization. [Jim Jagielski]
10372 *) Updated Configure: Configuration now uses AddModule to specify
10373 module source or binary file location, relative to src directory.
10374 Modules can be dropped into modules/extra, or in their own
10375 directory, and modules can come with a Makefile or Configure can
10376 create one. Modules can add compiler or library information to
10377 generated Makefiles. [Paul Sutton]
10379 *) Source core re-organisation: distributed modules are now in
10380 modules/standard. All other source code is in main. OS-specific
10381 code is in os/{unix,emx,win32} directories. [Paul Sutton]
10383 *) mod_browser has been removed, since it's replaced by mod_setenvif.
10386 *) Fix another long-standing bug in sub_req_lookup_file where it would
10387 happily skip past access checks on subdirectories looked up with
10388 relative paths. (It's used by mod_dir, mod_negotiation,
10389 and mod_include.) [Dean Gaudet]
10391 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
10392 N is the number of <Directory> sections, and M is the number of
10393 components in the filename of an object.
10395 To achieve this optimization the following config changes were made:
10396 - Wildcards (* and ?, not the regex forms) in <Directory>s,
10397 <Files>s, and <Location>s now treat a slash as a special
10398 character. For example "/home/*/public_html" previously would
10399 match "/home/a/andrew/public_html", now it only matches things
10400 like "/home/bob/public_html". This mimics /bin/sh behaviour.
10401 - It's possible now to use [] wildcarding in <Directory>, <Files>
10403 - Regex <Directory>s are applied after all non-regex <Directory>s.
10407 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
10408 and corrupted paths. [Dean Gaudet]
10410 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
10411 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
10412 be accessed now via backreferences $1..$9 in RewriteConds test-against
10413 strings in addition to RewriteRules subst string. Second the grouped
10414 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
10415 via backreferences %1..%9 both in following RewriteCond test-against
10416 strings and RewriteRules subst string. This provides maximum flexibility
10417 through the use of backreferences.
10418 Additionally the rewriting engine was cleaned up by putting common
10419 code to the new expand_backrefs_inbuffer() function.
10420 [Ralf S. Engelschall]
10422 *) When merging the main server's <Directory> and <Location> sections into
10423 a vhost, put the main server's first and the vhost's second. Otherwise
10424 the vhost can't override the main server. [Dean Gaudet] PR#717
10426 *) The <Directory> code would merge and re-merge the same section after
10427 a match was found, possibly causing problems with some modules.
10430 *) ip-based vhosts are stored and queried using a hashing function, which
10431 has been shown to improve performance on servers with many ip-vhosts.
10432 Some other changes had to be made to accommodate this:
10433 - the * address for vhosts now behaves like _default_
10434 - the matching process now is:
10435 - match an ip-vhost directly via hash (possibly matches main
10437 - if that fails, just pretend it matched the main server
10438 - if so far only the main server has been matched, perform
10439 name-based lookups (ServerName, ServerAlias, ServerPath)
10440 *only on name-based vhosts*
10441 - if they fail, look for _default_ vhosts
10442 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
10444 *) dbmmanage overhaul:
10445 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
10446 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
10447 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
10448 - provide better seed for rand
10449 - prompt for password as per getpass(3) (turn off echo, read from
10451 - use "newstyle" crypt based on $Config{osname} ($^O)
10452 - will not add a user if already in database, use new `update' command
10454 - added `check' command to check a users' password
10455 - added `import' command to convert existing password text-files or
10456 dbm files exported with `view'
10457 - more descriptive usage, general cleanup, 'use strict' clean, etc.
10460 *) Added psocket() which is a pool form of socket(), various places within
10461 the proxy weren't properly blocking alarms while registering the cleanup
10462 for its sockets. bclose() now uses pclose() and pclosesocket(). There
10463 was a bug where the client socket was being close()d twice due a still
10464 registered cleanup. [Dean Gaudet]
10466 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
10469 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
10470 [Jason Venner <jason@idiom.com>] PR#667
10472 *) Enable ``=""'' for RewriteCond directives to match against
10473 the empty string. This is the preferred way instead of ``^$''.
10474 [Ralf S. Engelschall]
10476 *) Fixed an infinite loop in mod_imap for references above the server root
10477 [Dean Gaudet] PR#748
10479 *) mod_proxy now has a ReceiveBufferSize directive, similar to
10480 SendBufferSize, so that the TCP window can be set appropriately
10481 for LFNs. [Phillip A. Prindeville]
10483 *) mod_browser has been replaced by the more general mod_setenvif
10484 (courtesy of Paul Sutton). BrowserMatch* directives are still
10485 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
10486 UnSetEnvIfZero directives. [Ken Coar]
10488 *) "HostnameLookups double" forces double-reverse DNS to succeed in
10489 order for remote_host to be set (for logging, or for the env var
10490 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
10493 *) mod_access overhaul:
10494 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
10495 and cidr syntax (i.e. 10.1.0.0/16). PR#762
10496 - Critical path was sped up by pre-computing a few things at config time.
10497 - The undocumented syntax "allow user-agents" was removed,
10498 the replacement is "allow from env=foobar" combined with mod_browser.
10499 - When used with hostnames it now forces a double-reverse lookup
10500 no matter what the directory settings are. This double-reverse
10501 doesn't affect any of the other routines that use the remote
10502 hostname. In particular it's still passed to CGIs and the log
10503 without the double-reverse check. Related PR#860.
10506 *) When a large bwrite() occurs (larger than the internal buffer size),
10507 while there is already something in the buffer, apache will combine
10508 the large write and the buffer into a single writev(). (This is
10509 in anticipation of using mmap() for reading files.)
10512 *) In obscure cases where a partial socket write occurred while chunking,
10513 Apache would omit the chunk header/footer on the next block. Cleaned
10514 up other bugs/inconsistencies in error conditions in buff.c. Fixed
10515 a bug where a long pause in DNS lookups could cause the last packet
10516 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
10518 *) API: Added child_exit function to module structure. This is called
10519 once per "heavy-weight process" just before a server child exit()'s
10520 e.g. when max_requests_per_child is reached, etc.
10521 [Doug MacEachern, Dean Gaudet]
10523 *) mod_include cleanup showed that handle_else was being used to handle
10524 endif. It didn't cause problems, but it was cleaned up too.
10527 *) mod_cern_meta would attempt to find meta files for the directory itself
10528 in some cases, but not in others. It now avoids it in all cases.
10531 *) mod_mime_magic would core dump if there was a decompression error.
10532 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
10534 *) PORT: some variants of DGUX require -lsocket -lnsl
10535 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
10537 *) mod_autoindex now allows sorting of FancyIndexed directory listings
10538 by the various fields (name, size, et cetera), either in ascending
10539 or descending order. Just click on the column header. [Ken Coar]
10541 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
10542 CPUs like the Alpha. Apache still stores ints in pointers, but that's
10543 the relatively safe direction. [Dean Gaudet] PR#344
10545 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
10546 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
10548 *) child_main avoids an unneeded call to select() when there is only one
10549 listening socket. [Dean Gaudet]
10551 *) In the event that the server is starved for idle servers it will
10552 spawn 1, then 2, then 4, ..., then 32 servers each second,
10553 doubling each second. It'll also give a warning in the errorlog
10554 since the most common reason for this is a poor StartServers
10555 setting. The define MAX_SPAWN_RATE can be used to raise/lower
10556 the maximum. [Dean Gaudet]
10558 *) Apache now provides an effectively unbuffered connection for
10559 CGI scripts. This means that data will be sent to the client
10560 as soon as the CGI pauses or stops output; previously, Apache would
10561 buffer the output up to a fixed buffer size before sending, which
10562 could result in the user viewing an empty page until the CGI finished
10563 or output a complete buffer. It is no longer necessary to use an
10564 "nph-" CGI to get unbuffered output. Given that most CGIs are written
10565 in a language that by default does buffering (e.g. perl) this
10566 shouldn't have a detrimental effect on performance.
10568 "nph-" CGIs, which formerly provided a direct socket to the client
10569 without any server post-processing, were not fully compatible with
10570 HTTP/1.1 or SSL support. As such they would have had to implement
10571 the transport details, such as encryption or chunking, in order
10572 to work properly in certain situations. Now, the only difference
10573 between nph and non-nph scripts is "non-parsed headers".
10574 [Dean Gaudet, Sameer Parekh, Roy Fielding]
10576 *) If a BUFF is switched from buffered to unbuffered reading the first
10577 bread() will return whatever remained in the buffer prior to the
10578 switch. [Dean Gaudet]
10580 Changes with Apache 1.3a1
10582 *) Added another Configure helper script: TestLib. It determines
10583 if a specified library exists. [Jim Jagielski]
10585 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
10586 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
10589 *) PORT: Some architectures use size_t for various lengths in network
10590 functions such as accept(), and getsockname(). The definition
10591 NET_SIZE_T is used to control this. [Dean Gaudet]
10593 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
10594 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
10595 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
10597 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
10598 [Igor N Kovalenko <infoh@mail.wplus.net>]
10600 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
10601 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
10602 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
10603 [Dean Gaudet] related PR#875
10605 *) API: Correct child_init() slot declaration from int to void, to
10606 match the init() declaration. Update mod_example to use the new

10612 *) get_client_block() returns wrong length if policy is

10624 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
10626 *) Added NoProxy directive to avoid using ProxyRemote for selected

10629 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
10631 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
10632 header to the remote host in the proxy. [Sameer Parekh and
10635 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
10636 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
10637 URLs, fixed rewritelog(), fixed forced response code handling on
10638 redirects from within .htaccess files, disabled pipe locking under
10639 braindead SunOS 4.1.x, allow env variables to be set even on rules with
10640 no substitution, bugfixed situations where HostnameLookups is off, made
10641 mod_rewrite more thread-safe for NT port and fixed problem when creating
10642 an empty query string via "xxx?".
10643 This update also removes the copyright of Ralf S. Engelschall,
10644 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
10645 exclusively copyrighted by the Apache Group now. This happened because
10646 the author now has gifted mod_rewrite exclusively to the Apache Group and
10647 no longer maintains an external version.
10648 [Ralf S. Engelschall]
10650 *) API: Added child_init function to module structure. This is called
10651 once per "heavy-weight process" before any requests are handled.

10654 *) Anonymous_LogEmail was logging on each subrequest.
10655 [Dean Gaudet] PR#421, 868

10668 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
10669 directory indices to start with the contents of the HeaderName file
10670 if there is one. If there isn't one, the behaviour is unchanged.
10671 [Ken Coar, Roy Fielding, Andrey A. Chernov]
10673 *) WIN32: Modules can now be dynamically loaded DLLs using the
10674 LoadModule/LoadFile directives. Note that module DLLs must be
10675 compiled with the multithreaded DLL version of the runtime library.
10676 [Alexei Kosut and Ben Laurie]
10678 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
10679 This allows the admin to completely remove automatic indexing
10680 from the server, while still supporting the basic functions of
10681 trailing-slash redirects and DirectoryIndex files. Note that if
10682 you're carrying over an old Configuration file and you use directory
10683 indexing then you'll want to add:
10685 Module autoindex_module mod_autoindex.o

10701 of a file if the extension is unknown. Based on the unix file(1)
10702 command. [Ian Kluft <ikluft@cisco.com>]
10704 *) We now determine and display the time spent processing a
10705 request if desired. [Jim Jagielski]
10707 *) mod_status: PID field of "dead" child slots no longer displays
10708 main httpd process's PID. [Jim Jagielski]
10710 *) Makefile.nt added - to build all the bits from the command line:
10711 nmake -f Makefile.nt
10712 Doesn't yet work properly. [Ben Laurie]
10714 *) Default text of 404 error is now "Not Found" rather than the
10715 potentially misleading "File Not Found". [Ken Coar]
10717 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
10718 for the net if we require people that actually need this data to
10719 enable it. [Linus Torvalds]
10721 *) directory_walk() is an expensive function, keep a little more state to
10722 avoid needless string counting. Add two new functions make_dirstr_parent
10723 and make_dirstr_prefix which replace all existing uses of make_dirstr.
10724 The new functions are a little less general than make_dirstr, but
10725 work more efficiently (less memory, less string counting).
10728 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
10729 to LDFLAGS) to avoid complications with lex rules in make files.
10730 [Dean Gaudet] PR#372
10732 *) run_method optimized to avoid needless scanning over NULLs in the
10733 module list. [Dean Gaudet]
10735 *) Revamp of (unix) scoreboard management code such that it avoids
10736 unnecessary traversals of the scoreboard on each hit. This is
10737 particularly important for high volume sites with a large
10738 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
10739 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
10740 httpd.h. [Dean Gaudet]
10742 *) In configurations using multiple Listen statements it was possible for
10743 busy sockets to starve other sockets of service. [Dean Gaudet]
10745 *) Added hook so standalone_main can be replaced at compile time
10746 (define STANDALONE_MAIN)
10749 *) Lowest-level read/write functions in buff.c will be replaced with
10750 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
10751 compile time. The default sfio discipline will behave as apache
10752 would without sfio compiled in.
10755 *) Enhance UserDir directive (mod_userdir) to accept a list of
10756 usernames for the 'disable' keyword, and add 'enable user...' to
10757 selectively *en*able userdirs if they're globally disabled.
10760 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
10761 will work with Netscape dbm files. (dbmmanage will probably not
10762 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
10764 *) Add a ListenBacklog directive to control the backlog parameter
10765 passed to listen(). Also change the default to 511 from 512.
10768 *) API: A new handler response DONE which informs apache that the
10769 request has been handled and it can finish off quickly, similar to
10770 how it handles errors. [Rob Hartill]
10772 *) Turn off chunked encoding after sending terminating chunk/footer
10773 so that we can't do it twice by accident. [Roy Fielding]
10775 *) mod_expire also issues Cache-Control: max-age headers.
10778 *) API: Added kill_only_once option for free_proc_chain so that it won't
10779 aggressively try to kill off specific children. For fastcgi.
10780 [Stanley Gambarin <gambarin@OpenMarket.com>]
10782 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
10784 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
10785 When used together, these cause mod_dir to emit HEIGHT and WIDTH
10786 attributes in the FancyIndexing IMG tags. [Ken Coar]
10788 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
10790 *) PORT: Added Windows NT support
10791 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
10793 Changes with Apache 1.2.6
10795 *) mod_include when using XBitHack Full would send ETags in addition to
10796 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
10797 [Dean Gaudet] PR#1133
10799 *) SECURITY: When a client connects to a particular port/addr, and
10800 gives a Host: header ensure that the virtual host requested can
10801 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
10803 *) Support virtual hosts with wildcard port and/or multiple ports
10804 properly. [Ed Korthof <ed@organic.com>]
10806 *) Fixed some case-sensitivity issues according to RFC2068.
10809 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
10810 and mod_include.c. [Dean Gaudet]
10812 *) Variable 'cwd' was being used pointlessly before being set.
10815 *) SIGURG doesn't exist on all platforms.
10816 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
10818 *) When an error occurs during a POST, or other operation with a
10819 request body, the body has to be read from the net before allowing
10820 a keepalive session to continue. [Roy Fielding] PR#1399
10822 *) When an error occurs in fcntl() locking suggest the user look up
10823 the docs for LockFile. [Dean Gaudet]
10825 *) table_set() and table_unset() did not deal correctly with
10826 multiple occurrences of the same key. [Stephen Scheck
10827 <sscheck@infonex.net>, Ben Laurie] PR#1604
10829 *) send_fd_length() did not calculate total_bytes_sent properly in error
10830 cases. [Ben Reser <breser@regnow.com>] PR#1366
10832 *) r->connection->user was allocated in the wrong pool causing corruption
10833 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
10835 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10836 Also removed the auto-generated link to www.apache.org that was the
10837 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10839 *) Multiple "close" tokens may have been set in the "Connection"
10840 header, not an error, but a waste.
10841 [Ronald.Tschalaer@psi.ch] PR#1683
10843 *) "basic" and "digest" auth tokens should be tested case-insensitive.
10844 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
10846 *) It appears the "257th byte" bug (see
10847 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
10848 at the 256th byte as well. Fixed. [Dean Gaudet]
10850 *) mod_rewrite would not handle %3f properly in some situations.
10853 *) Apache could generate improperly chunked HTTP/1.1 responses when
10854 the bputc() or rputc() functions were used by modules (such as
10855 mod_include). [Dean Gaudet]
10857 *) #ifdef wrap a few #defines in httpd.h to make life easier on
10858 some ports. [Ralf Engelschall]
10860 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
10862 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
10864 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
10866 Changes with Apache 1.2.5
10868 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
10869 only an issue on systems without a MAXDNAME define or where
10870 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
10872 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
10875 *) Fix core dump in the ftp proxy when reading incorrectly formatted
10876 directory listings. [Marc Slemko]
10878 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
10881 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
10882 is used to read various types of files such as htaccess and
10883 htpasswd files. [Marc Slemko]
10885 *) SECURITY: Ensure that the buffer returned by ht_time is always
10886 properly null terminated. [Marc Slemko]
10888 *) SECURITY: General mod_include cleanup, including fixing several
10889 possible buffer overflows and a possible infinite loop. This cleanup
10890 was done against 1.3 code and then backported to 1.2, the result
10891 is a large difference (due to indentation cleanup in 1.3 code).
10892 Users interested in seeing a smaller set of relevant differences
10893 should consider comparing against src/modules/standard/mod_include.c
10894 from the 1.3b3 release. Non-indentation changes to mod_include
10895 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
10897 *) SECURITY: Numerous changes to mod_imap in a general cleanup
10898 including fixing a possible buffer overflow. This cleanup also
10899 was done with 1.3 code as a basis, see the the previous note
10900 about mod_include. [Dean Gaudet]
10902 *) SECURITY: If a htaccess file can not be read due to bad
10903 permissions, deny access to the directory with a HTTP_FORBIDDEN.
10904 The previous behavior was to ignore the htaccess file if it could not
10905 be read. This change may make some setups with unreadable
10906 htaccess files stop working. PR#817 [Marc Slemko]
10908 *) SECURITY: no2slash() was O(n^2) in the length of the input.
10909 Make it O(n). This inefficiency could be used to mount a denial
10910 of service attack against the Apache server. Thanks to
10911 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
10912 this. [Dean Gaudet]
10914 *) mod_include used uninitialized data for some uses of && and ||.
10915 [Brian Slesinsky <bslesins@wired.com>] PR#1139
10917 *) mod_imap should decline all non-GET methods.
10918 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
10920 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10922 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10923 r->filename. Since those two are meant to be in sync with each other
10924 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
10926 *) mod_include did not properly handle all possible redirects from sub-
10927 requests. [Ken Coar]
10929 *) Inetd mode (which is buggy) uses timeouts without having setup the
10930 jmpbuffer. [Dean Gaudet] PR#1064

10933 reporting a select error over and over.

10936 Changes with Apache 1.2.4
10938 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
10939 always making requests with the full-URI instead of just the URI path.
10940 [Marc Slemko, Roy Fielding]
10942 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
10943 on this platform. [Marc Slemko]
10945 Changes with Apache 1.2.3
10947 *) The request to a remote proxy was mangled if it was generated as the
10948 result of a ProxyPass directive. URL schemes other than http:// were not
10949 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
10950 PR#812 [Lars Eilebrecht]
10952 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10953 information for case where proxy module is not available. [Marc Slemko]
10955 *) Force proxy to always respond as HTTP/1.0, which it was failing to
10956 do for errors and cached responses. [Roy Fielding]
10958 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
10960 Changes with Apache 1.2.2 [not released]
10962 *) Fixed another long-standing bug in sub_req_lookup_file where it would
10963 happily skip past access checks on subdirectories looked up with relative
10964 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
10967 *) Add lockfile name to error message printed out when
10968 USE_FLOCK_SERIALIZED_ACCEPT is defined.
10971 *) Enhanced the chunking and error handling inside the buffer functions.
10972 [Dean Gaudet, Roy Fielding]
10974 *) When merging the main server's <Directory> and <Location> sections into
10975 a vhost, put the main server's first and the vhost's second. Otherwise
10976 the vhost can't override the main server. [Dean Gaudet] PR#717
10978 *) The <Directory> code would merge and re-merge the same section after
10979 a match was found, possibly causing problems with some modules.
10982 *) Fixed an infinite loop in mod_imap for references above the server root.
10983 [Dean Gaudet] PR#748
10985 *) mod_include cleanup showed that handle_else was being used to handle
10986 endif. It didn't cause problems, but it was cleaned up too.
10989 *) Last official synchronization of mod_rewrite with author version (because
10990 mod_rewrite is now directly developed by the author at the Apache Group):
10991 o added diff between mod_rewrite 3.0.6+ and 3.0.9
10992 minus WIN32/NT stuff, but plus copyright removement.
10994 - workaround for detecting infinite rewriting loops
10995 - fixed setting of env vars when "-" is used as subst string
10996 - fixed forced response code on redirects (PR#777)
10997 - fixed cases where r->args is ""
10998 - kludge to disable locking on pipes under braindead SunOS
10999 - fix for rewritelog in cases where remote hostname is unknown
11000 - fixed totally damaged request_rec walk-back loop
11001 o remove static from local data and add static to global ones.
11002 o replaced ugly proxy finding stuff by simple
11003 find_linked_module("mod_proxy") call.
11004 o added missing negation char on rewritelog()
11005 o fixed a few comment typos
11006 [Ralf S. Engelschall]
11008 *) Anonymous_LogEmail was logging on each subrequest.
11009 [Dean Gaudet] PR#421, PR#868
11011 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11012 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11013 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11014 Additionally mod_browser now triggers during translate_name to workaround
11015 a deficiency in the header_parse phase.

11033 under Solaris 2.x (up through 2.5.1). It has been fixed.
11034 [Dean Gaudet] PR#832
11036 *) API: In HTTP/1.1, whether or not a request message contains a body
11037 is independent of the request method and based solely on the presence
11038 of a Content-Length or Transfer-Encoding. Therefore, our default
11039 handlers need to be prepared to read a body even if they don't know
11040 what to do with it; otherwise, the body would be mistaken for the
11041 next request on a persistent connection. discard_request_body()
11042 has been added to take care of that. [Roy Fielding] PR#378
11044 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
11045 release version number, such that it always increases along the
11046 same lines as our source code branching. [Roy Fielding]
11048 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
11050 Changes with Apache 1.2.1
11052 *) SECURITY: Don't serve file system objects unless they are plain files,
11053 symlinks, or directories. This prevents local users from using pipes
11054 or named sockets to invoke programs for an extremely crude form of

11058 could contain "../" allowing a local user to "publish" any file on
11059 the system. No slashes are allowed now. [Dean Gaudet]
11061 *) SECURITY: It was possible to violate the symlink Options using mod_dir
11062 (headers, readmes, titles), mod_negotiation (type maps), or
11063 mod_cern_meta (meta files). [Dean Gaudet]
11065 *) SECURITY: Apache will refuse to run as "User root" unless
11066 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
11068 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
11069 if it contained a .htaccess disallowing symlinks. This is contrary
11070 to the rule that symlink permissions are tested with the symlink
11071 options of the parent directory. [Dean Gaudet] PR#353
11073 *) CONFIG: The LockFile directive can be used to place the serializing
11074 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
11075 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
11078 *) Request processing now retains state of whether or not the request
11079 body has been read, so that internal redirects and subrequests will
11080 not try to read it twice (and block). [Roy Fielding]

11092 handle high numbered descriptors (examples include bind, and
11093 solaris libc). On all systems apache attempts to keep all permanent
11094 descriptors above 15 (called the low slack line). Solaris users
11095 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
11096 which keeps all non-FILE * descriptors above 255. On all systems
11097 this should make supporting large numbers of vhosts with many open
11098 log files more feasible. If this causes trouble please report it,
11099 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
11100 [Dean Gaudet] various PRs
11102 *) Related to the last entry, network sockets are now opened before
11103 log files are opened. The only known case where this can cause
11104 problems is under Solaris with many virtualhosts and many Listen
11105 directives. But using -DHIGH_SLACK_LINE=256 described above will
11106 work around this problem. [Dean Gaudet]

11216 and 304 responses) and err_headers_out (headers sent with all responses).
11217 Avoid the overhead of copying tables if err_headers_out is empty
11218 (the usual case). [Roy Fielding]
11220 *) Fixed a couple places where a check for the default Content-Type was
11221 not properly checking both the value configured by the DefaultType
11222 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
11223 of DEFAULT_TYPE to match the documented default (text/plain).
11224 [Dean Gaudet] PR#506
11226 *) Escape the HTML-sensitive characters in the Request-URI that is
11227 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
11229 *) Properly initialize the flock structures used by the mutex locking
11230 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
11233 *) The method for determining PATH_INFO has been restored to the pre-1.2b
11234 (and NCSA httpd) definition wherein it was the extra path info beyond
11235 the CGI script filename. The environment variable FILEPATH_INFO has
11236 been removed, and instead we supply the original REQUEST_URI to any
11237 script that wants to be Apache-specific and needs the real URI path.
11238 This solves a problem with existing scripts that use extra path info
11239 in the ScriptAlias directive to pass options to the CGI script.
11242 *) The _default_ change in 1.2b10 will change the behaviour on configs
11243 that use multiple Listen statements for listening on multiple ports.
11244 But that change is necessary to make _default_ consistent with other
11245 forms of <VirtualHost>. It requires such configs to be modified
11246 to use <VirtualHost _default_:*>. The documentation has been
11247 updated. [Dean Gaudet] PR#530
11249 *) If an ErrorDocument CGI script is used to respond to an error
11250 generated by another CGI script which has already read the message
11251 body of the request, the server would block trying to read the
11252 message body again. [Rob Hartill]
11254 *) signal() replacement conflicted with a define on QNX (and potentially
11255 other platforms). Fixed. [Ben Laurie] PR#512
11257 Changes with Apache 1.2b10
11259 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
11260 to be configured via -D in Configuration. [Dean Gaudet] PR#449
11262 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
11264 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
11266 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
11267 config, in case the hostent struct returned is trash.
11268 [Chuck Murcko] PR #491
11270 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
11271 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
11273 Changes with Apache 1.2b9 [never announced]
11275 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
11276 changes and in anticipation of 1.2 final release. [Roy Fielding]
11278 *) Fix problem with scripts not receiving a SIGPIPE when client drops
11279 the connection (e.g., when user presses Stop). Apache will now stop
11280 trying to send a message body immediately after an error from write.
11281 [Roy Fielding and Nathan Kurz] PR#335
11283 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
11284 than mod_alias, and mod_alias has higher priority than mod_proxy;
11285 rearranged other modules to enhance understanding of their purpose
11286 and relative order (and maybe even reduce some overhead).
11287 [Roy Fielding and Sameer Parekh]
11289 *) Fix graceful restart. Eliminate many signal-related race
11290 conditions in both forms of restart, and in SIGTERM. See
11291 htdocs/manual/stopping.html for details on stopping and
11292 restarting the parent. [Dean Gaudet]
11294 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
11295 memory allocator to avoid a behaviour that required extra blocks to
11296 be allocated. [Dean Gaudet]
11298 *) Allow suexec to access files relative to current directory but not
11299 above. (Excluding leading / or any .. directory.) [Ken Coar]
11302 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
11303 PR#367, 368, 354, 453
11305 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
11306 while obtaining the /~user and save the username in a separate data
11307 area so that it won't be overwritten by the call to getgrgid(), and
11308 fix some misuse of the pool string allocation functions. Also fixes
11309 a general problem with parsing URL query info into args for CGI scripts.
11310 [Roy Fielding] PR#339, 367, 354, 453
11312 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
11314 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
11316 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
11317 AuthDBAuthoritative. [Marc Slemko] PR#420
11319 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
11321 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
11322 object that can't be PUT, or FOOBAR for some method FOOBAR that
11323 apache doesn't know about at all). Log 404s that occur in mod_include.
11324 [Paul Sutton, John Van Essen]
11326 *) If a soft timeout (or lingerout) occurs while trying to flush a
11327 buffer or write inside buff.c or fread'ing from a CGI's output,
11328 then the timeout would be ignored. [Roy Fielding] PR#373
11330 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
11331 parsing of headers. If the terminating empty-line CRLF occurs starting
11332 at the 256th or 257th byte of output, then Navigator will think a normal
11333 image is invalid. We are guessing that this is because their initial
11334 read of a new request uses a 256 byte buffer. We check the bytes written
11335 so far and, if we are about to tickle the bug, we instead insert a
11336 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
11338 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
11339 of an external redirection. [Roy Fielding and Paul Sutton]
11341 *) Configure would create a broken Makefile if the configuration file
11342 contained a commented-out Rule. [Roy Fielding]
11344 *) Promote per_dir_config and subprocess_env from the subrequest to the
11345 main request in mod_negotiation. In particular this fixes a bug
11346 where <Files> sections wouldn't properly apply to negotiated content.
11349 *) Fix a potential deadlock in mod_cgi script_err handling.
11350 [Ralf S. Engelschall]
11352 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
11353 [Mitchell Blank Jr]
11355 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
11356 .htaccess files because the RewriteBase was not replaced correctly.
11357 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
11358 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
11360 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
11361 1.x the settings are those of pre-1.2b8. For 2.x we include
11362 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
11363 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
11364 [Dean Gaudet] PR#336, PR#340
11366 *) Redirect did not preserve ?query_strings when present in the client's
11367 request. [Dean Gaudet]
11369 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
11371 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
11373 *) Add UnixWare compile/install instructions. [Chuck Murcko]
11375 *) Add mod_example (illustration of API techniques). [Ken Coar]
11377 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
11379 *) Improve handling of directories when filenames have spaces in them.
11382 *) For hosts with multiple IP addresses, try all additional addresses if
11383 necessary to get a connect. Fail only if hostent address list is
11384 exhausted. [Chuck Murcko]
11386 *) More signed/unsigned port fixes. [Dean Gaudet]
11388 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
11391 Changes with Apache 1.2b8
11393 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
11394 to it. [Marc Slemko]
11396 *) The addition of <Location> and <File> directives made the
11397 sub_req_lookup_simple() function bogus, so we now handle
11398 the special cases directly. [Dean Gaudet]
11400 *) We now try to log where the server is dumping core when a fatal
11401 signal is received. [Ken Coar]
11403 *) Improved lingering_close by adding a special timeout, removing the
11404 spurious log messages, removing the nonblocking settings (they
11405 are not needed with the better timeout), and adding commentary
11406 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
11407 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
11409 *) Send error messages about setsockopt failures to the server error
11410 log instead of stderr. [Roy Fielding]
11412 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
11414 *) Stopgap solution for CGI 3-second delay with server-side includes: if
11415 processing a subrequest, allocate memory from r->main->pool instead
11416 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
11417 in the middle of an SSI request. [Dean Gaudet] PR #122
11419 *) Fixed status of response when POST is received for a nonexistent URL
11420 (was sending 405, now 404) and when any method is sent with a
11421 full-URI that doesn't match the server and the server is not acting
11422 as a proxy (was sending 501, now 403). [Roy Fielding]
11424 *) Host port changed to unsigned short. [Ken Coar] PR #276
11426 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
11428 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
11430 *) Report extra info from errno with many errors that cause httpd to exit.
11431 spawn_child, popenf, and pclosef now have valid errno returns in the
11432 event of an error. Correct problems where errno was stomped on
11433 before being reported. [Dean Gaudet]
11435 *) In the proxy, if the cache filesystem was full, garbage_coll() was
11436 never called, and thus the filesystem would remain full indefinitely.
11437 We now also remove incomplete cache files left if the origin server
11438 didn't send a Content-Length header and either the client has aborted
11439 transfer or bwrite() to client has failed. [Petr Lampa]
11441 *) Fixed the handling of module and script-added header fields.
11442 Improved the interface for sending header fields and reduced
11443 the duplication of code between sending okay responses and errors.
11444 We now always send both headers_out and err_headers_out, and
11445 ensure that the server-reserved fields are not being overridden,
11446 while not overriding those that are not reserved. [Roy Fielding]
11448 *) Moved transparent content negotiation fields to err_headers_out
11449 to reflect above changes. [Petr Lampa]
11451 *) Fixed the determination of whether or not we should make the
11452 connection persistent for all of the cases where some other part
11453 of the server has already indicated that we should not. Also
11454 improved the ordering of the test so that chunked encoding will
11455 be set whenever it is desired instead of only when KeepAlive
11456 is enabled. Added persistent connection capability for most error
11457 responses (those that do not indicate a bad input stream) when
11458 accessed by an HTTP/1.1 client. [Roy Fielding]
11460 *) Added missing timeouts for sending header fields, error responses,
11461 and the last chunk of chunked encoding, each of which could have
11462 resulted in a process being stuck in write forever. Using soft_timeout
11463 requires that the sender check for an aborted connection rather than
11464 continuing after an EINTR. Timeouts that used to be initiated before
11465 send_http_header (and never killed) are now initiated only within or
11466 around the routines that actually do the sending, and not allowed to
11467 propagate above the caller. [Roy Fielding]
11469 *) mod_auth_anon required an @ or a . in the email address, not both.
11472 *) per_dir_defaults weren't set correctly until directory_walk for
11473 name-based vhosts. This fixes an obscure bug with the wrong config
11474 info being used for vhosts that share the same ip as the server.
11477 *) Improved generation of modules/Makefile to be more generic for
11478 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
11480 *) Generate makefile dependency for Configuration based on the actual
11481 name given when running the Configure process. [Dean Gaudet]
11483 *) Fixed problem with vhost error log not being set prior to
11484 initializing virtual hosts. [Dean Gaudet]
11486 *) Fixed infinite loop when a trailing slash is included after a type map
11487 file URL (extra path info). [Petr Lampa]
11489 *) Fixed server status updating of per-connection counters. [Roy Fielding]
11491 *) Add documentation for DNS issues (reliability and security), and try
11492 to explain the virtual host matching process. [Dean Gaudet]
11494 *) Try to continue gracefully by disabling the vhost if a DNS lookup
11495 fails while parsing the configuration file. [Dean Gaudet]
11497 *) Improved calls to setsockopt. [Roy Fielding]
11499 *) Negotiation changes: Don't output empty content-type in variant list;
11500 Output charset in variant list; Return sooner from handle_multi() if
11501 no variants found; Add handling of '*' wildcard in Accept-Charset.
11502 [Petr Lampa and Paul Sutton]
11504 *) Fixed overlaying of request/sub-request notes and headers in
11505 mod_negotiation. [Dean Gaudet]
11507 *) If two variants' charset quality are equal and one is the default
11508 charset (iso-8859-1), then prefer the variant that was specifically
11509 listed in Accept-Charset instead of the default. [Petr Lampa]
11511 *) Memory allocation problem in push_array() -- it would corrupt memory
11512 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
11514 *) invoke_handler() doesn't handle mime arguments in content-type
11515 [Petr Lampa] PR#160
11517 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
11520 *) Fixed problem with ErrorDocument not working for virtual hosts
11521 due to one of the performance changes in 1.2b7. [Dean Gaudet]
11523 *) Log an error message if we get a request header that is too long,
11524 since it may indicate a buffer overflow attack. [Marc Slemko]
11526 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
11527 not reject URLs without a double-slash, as per RFC2068 section 3.2.
11528 [Ken Coar] PR #146, #187
11530 *) Added table entry placeholder for new header_parser callback
11531 in all of the distributed modules. [Ken Coar] PR #191
11533 *) Allow for cgi files without the .EXE extension on them under OS/2.
11534 [Garey Smiley] PR #59
11536 *) Fixed error message when resource is not found and URL contains
11537 path info. [Petr Lampa and Dean Gaudet] PR #40
11539 *) Fixed user and server confusion over what should be a virtual host
11540 and what is the main server, resulting in access to something
11541 other than the name defined in the virtualhost directive (but
11542 with the same IP address) failing. [Dean Gaudet]
11544 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
11545 AIX; improves the redirection stuff to enable the users to generally
11546 redirect to http, https, gopher and ftp; added TIME variable for
11547 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
11548 special patterns >STRING, <STRING and =STRING to RewriteCond, which
11549 can be used in conjunction with %{TIME} or other variables to create
11550 time-dependent rewriting rules. [Ralf S. Engelschall]
11552 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
11553 Module authors may need to adjust their code for proper cleanup to take
11554 place (that is, call note_cleanups_for_fd()). This change fixes problems
11555 with file descriptors being erroneously closed when the proxy module was
11556 in use. [Ben Laurie]
11558 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
11559 initgroups() to hose the group information needed for later
11560 comparisons. [Randy Terbush]
11562 *) Remove unnecessary call to va_end() in create_argv() which
11563 caused a SEGV on some systems.
11565 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
11568 *) Clear memory allocated for listeners. [Randy Terbush]
11570 *) Improved handling of IP address as a virtualhost address and
11571 introduced "_default_" as a synonym for the default vhost config.
11572 [Dean Gaudet] PR #212
11574 Changes with Apache 1.2b7

11580 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
11581 - replace protocol response numbers with symbols
11582 - save variant-list into main request notes
11583 - free allocated memory from subrequests
11584 - merge notes, headers_out and err_headers_out
11586 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
11587 "HTTP/#.# ###*" to be more lenient about what we accept.
11590 *) more proxy FTP bug fixes:
11591 - Changed send_dir() to remove user/passwd from displayed URL.
11592 - Changed login error messages to be more descriptive.
11593 - remove setting of SO_DEBUG socket option
11594 - Make ftp_getrc() more lenient about multiline responses,
11595 specifically, 230 responses which don't have continuation 230-
11596 on each line). These seem to be all NT FTP servers, and while
11597 perhaps questionable, they appear to be legal by RFC 959.
11598 - Add missing kill_timeout() after transfer to user completes.
11601 *) Fixed problem where a busy server could hang when restarting
11602 after being sent a SIGHUP due to child processes not exiting.
11605 *) Modify mod_include escaping so a '\' only signifies an escaped
11606 character if the next character is one that needs
11607 escaping. [Ben Laurie]
11609 *) Eliminated possible infinite loop in mod_imap when relative URLs are
11610 used with a 'base' directive that does not have a '/' in it.
11611 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
11613 *) Reduced the default timeout from 1200 seconds to 300, and the
11614 one in the sample configfile from 400 to 300. [Marc Slemko]
11616 *) Stop vbprintf from crashing if given a NULL string pointer;
11617 print (null) instead. [Ken Coar]
11619 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
11620 [Marc Slemko and Roy Fielding]
11622 *) Fixed problem with mod_cgi-generated internal redirects trying to
11623 read the request message-body twice. [Archie Cobbs and Roy Fielding]
11625 *) Reduced timeout on lingering close, removed possibility of a blocked
11626 read causing the child to hang, and stopped logging of errors if
11627 the socket is not connected (reset by client). [Roy Fielding]
11629 *) Rearranged main child loop to remove duplication of code in
11630 select/accept and keep-alive requests, fixed several bugs regarding
11631 checking scoreboard_image for exit indication and failure to
11632 account for all success conditions and trap all error conditions,
11633 prevented multiple flushes before closing the socket; close the entire
11634 socket buffer instead of just one descriptor, prevent logging of
11635 EPROTO and ECONNABORTED on platforms where supported, and generally
11636 improved readability. [Roy Fielding]
11638 *) Extensive performance improvements. Cleaned up inefficient use of
11639 auto initializers, multiple is_matchexp calls on a static string,
11640 and excessive merging of response_code_strings. [Dean Gaudet]
11642 *) Added double-buffering to mod_include to improve performance on
11643 server-side includes. [Marc Slemko]
11645 *) Several fixes for suexec wrapper. [Randy Terbush]
11646 - Make wrapper work for files on NFS filesystem.
11647 - Fix portability problem of MAXPATHLEN.
11648 - Fix array overrun problem in clean_env().
11649 - Fix allocation of PATH environment variable
11651 *) Removed extraneous blank line is description of mod_status chars.
11654 *) Logging of errors from the call_exec routine simply went nowhere,
11655 since the logfile fd has been closed, so now we send them to stderr.
11656 [Harald T. Alvestrand]
11658 *) Fixed core dump when DocumentRoot is a CGI.
11659 [Ben Laurie, reported by geddis@tesserae.com]
11661 *) Fixed potential file descriptor leak in mod_asis; updated it and
11662 http_core to use pfopen/pfclose instead of fopen/fclose.
11663 [Randy Terbush and Roy Fielding]
11665 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
11666 as the DEC Alpha which is 64-bit but uses 32-bit ints.
11667 [Dean Gaudet and Ken Coar]
11669 *) Return a 302 response code to the client when sending a redirect
11670 due to a missing trailing '/' on a directory instead of a 301; now
11671 it is cacheable. [Markus Gyger]
11673 *) Fix condition where, if a bad directive occurs in .htaccess, and
11674 sub_request() goes first to this directory, then log_reason() will
11675 SIGSEGV because it doesn't have initialized r->per_dir_config.
11676 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
11678 *) Fix handling of lang_index in is_variant_better(). This was
11679 causing problems which resulted in the server sending the
11680 wrong language document in some cases. [Petr Lampa]
11682 *) Remove free() from clean_env() in suexec wrapper. This was nuking
11683 the clean environment on some systems.
11685 *) Tweak byteserving code (e.g. serving PDF files) to work around
11686 bugs in Netscape Navigator and Microsoft Internet Explorer.
11687 Emit Content-Length header when sending multipart/byteranges.

11696 given to RLimit* directives. [Ed Korthof]
11698 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
11700 *) Improved buffered output to the client by delaying the flush decision
11701 until the BUFF code is actually about to read the next request.
11702 This fixes a problem introduced in 1.2b5 with clients that send
11703 an extra CRLF after a POST request. Also improved chunked output
11704 performance by combining writes using writev() and removing as
11705 many bflush() calls as possible. NOTE: Platforms without writev()
11706 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
11707 or Configure, unless we have already done so. [Dean Gaudet]
11709 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
11711 *) Fixed mod_info output corruption bug introduced by buffer overflow
11712 fixes. [Dean Gaudet]
11714 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
11715 for the special case of a 304 response. [Paul Sutton]
11717 *) Improved handling of TRACE method by bypassing normal method handling
11718 and header parsing routines; fixed Allow response to always allow TRACE.
11721 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
11723 *) Cleaned-up some of the generated HTML. [Ken Coar]
11725 Changes with Apache 1.2b6
11727 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
11729 *) Fix typo introduced in fix for potential infinite loop around
11730 accept() in child_main(). This change caused the rev to 1.2b6.
11731 1.2b5 was never a public beta.

11735 *) Change KeepAlive semantics (On|Off instead of a number), add
11736 MaxKeepAliveRequests directive. [Alexei Kosut]
11738 *) Various NeXT compilation patches, as well as a change in
11739 regex/regcomp.c since that file also used a NEXT define.
11742 *) Allow * to terminate the end of a directory match in mod_dir.
11743 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
11745 *) Don't call can_exec() if suexec_enabled. Calling this requires
11746 scripts executed by the suexec wrapper to be world executable, which
11747 defeats one of the advantages of running the wrapper. [Randy Terbush]
11749 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
11752 *) Migration from sprintf() to snprintf() to avoid buffer
11753 overflows. [Marc Slemko]
11755 *) Provide portable snprintf() implementation (ap_snprintf)
11756 as well as *cvt family. [Jim Jagielski]
11758 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
11761 *) Remove mod_fastcgi.c from the distribution. This module appears
11762 to be maintained more through the Open Market channels and should
11763 continue to be easily available at http://www.fastcgi.com/
11765 *) Fixed bug in modules/Makefile that wouldn't allow building in more
11766 than one subdirectory (or cleaning, either). [Jeremy Laidman]
11768 *) mod_info assumed that the config files were relative to ServerRoot.
11771 *) CGI scripts called as an error document resulting from failed
11772 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
11774 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
11777 *) Properly check errno to prevent display of a directory index
11778 when server receives a long enough URL to confuse stat().
11781 *) Several security enhancements to suexec wrapper. It is _highly_
11782 recommended that previously installed versions of the wrapper
11783 be replaced with this version. [Randy Terbush, Jason Dour]
11785 - ~user execution now properly restricted to ~user's home
11786 directory and below.
11787 - execution restricted to UID/GID > 100
11788 - restrict passed environment to known variables
11789 - call setgid() before initgroups() (portability fix)
11790 - remove use of setenv() (portability fix)
11792 *) Add HTTP/1.0 response forcing. [Ben Laurie]
11794 *) Add access control via environment variables. [Ben Laurie]
11796 *) Add rflush() function. [Alexei Kosut]
11798 *) remove duplicate pcalloc() call in new_connection().
11800 *) Fix incorrect comparison which could allow number of children =
11801 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
11802 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
11804 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
11805 AIX PS/2, CONVEXOS. [Jim Jagielski]
11807 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
11808 It's more portable. [Martin Kraemer]
11810 *) Replace references to make in Makefile.tmpl with $(MAKE).
11813 *) Add ProxyBlock directive w/IP address caching. Add IP address
11814 caching to NoCache directive as well. ProxyBlock works with all
11815 handlers; NoCache now also works with FTP for anonymous logins.
11816 Still more code cleanup. [Chuck Murcko]
11818 *) Add "header parse" API hook [Ben Laurie]
11820 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
11822 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
11824 *) Correctly allow access and auth directives in <Files> sections in
11825 server config files. [Alexei Kosut]
11827 *) Fix bug with ServerPath that could cause certain files to be not
11828 found by the server. [Alexei Kosut]
11830 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
11831 double-quote from text and so that it properly checks for unsupported
11832 status codes using the new index_of_response interface. [Roy Fielding]
11834 *) Multiple fixes to the lingering_close code in order to avoid being
11835 interrupted by a stray timeout, to avoid lingering on a connection
11836 that has already been aborted or never really existed, to ensure that
11837 we stop lingering as soon as any error condition is received, and to
11838 prevent being stuck indefinitely if the read blocks. Also improves
11839 reporting of error conditions. [Marc Slemko and Roy Fielding]
11841 *) Fixed initialization of parameter structure for sigaction.
11842 [mgyger@itr.ch, Adrian Filipi-Martin]
11844 *) Fixed reinitializing the parameters before each call to accept and
11845 select, and removed potential for infinite loop in accept.
11846 [Roy Fielding, after useful PR from adrian@virginia.edu]
11848 *) Fixed condition where, if a child fails to fork, the scoreboard would
11849 continue to say SERVER_STARTING forever. Eventually, the main process
11850 would refuse to start new children because count_idle_servers() will
11851 count those SERVER_STARTING entries and will always report that there
11852 are enough idle servers. [Phillip Vandry]
11854 *) Fixed bug in bcwrite regarding failure to account for partial writes.
11855 Avoided calling bflush() when the client is pipelining requests.
11856 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
11858 *) Added description of "." mode in server-status [Jim Jagielski]
11860 Changes with Apache 1.2b4
11862 *) Fix possible race condition in accept_mutex_init() that
11863 could leave a small security hole open allowing files to be
11864 overwritten in cases where the server UID has write permissions.
11867 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
11869 *) Fix portablity problem in util_script where ARG_MAX may not be
11870 defined for some systems.
11872 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
11875 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
11876 style magic #! token for better script portability. [Garey Smiley]
11878 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
11879 execution for ~userdir CGI. [Jason Dour]
11881 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
11883 *) Fix month off by one in suexec wrapper logging.
11885 Changes with Apache 1.2b3:
11887 *) Fix error in mod_cgi which could cause resources not to be properly
11888 freed, or worse. [Dean Gaudet]
11890 *) Fix find_string() NULL pointer dereference. [Howard Fear]
11892 *) Add set_flag_slot() at the request of Dirk and others.
11895 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
11897 *) Add changes to improve the error message given for invalid
11898 ServerName parameters. [Dirk vanGulik]
11900 *) Add "Authoritative" directive for Auth modules that don't
11901 currently have it. This gives admin control to assign authoritative
11902 control to an authentication scheme and allow "fall through" for
11903 those authentication modules that aren't "Authoritative" thereby
11904 allowing multiple authentication mechanisms to be chained.
11907 *) Remove requirement for ResourceConfig/AccessConfig if not using
11908 the three config file layout. [Randy Terbush]
11910 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
11912 *) Changes to suexec wrapper to fix the following problems:
11913 1. symlinked homedirs will kill ~userdirs.
11914 2. initgroups() on Linux 2.0.x clobbers gr->grid.
11915 3. CGI command lines paramters problems
11916 4. pw-pwdir for "docroot check" still the httpd user's pw record.
11917 [Randy Terbush, Jason Dour]
11919 *) Change create_argv() to accept variable arguments. This fixes
11920 a problem where arguments were not getting passed to the CGI via
11921 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
11923 *) Collapse multiple slashes in path URLs to properly apply
11924 handlers defined by <Location>. [Alexei Kosut]
11926 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
11928 *) Improve the accuracy of request duration timings by setting
11929 r->request_time in read_request_line() instead of read_request().
11932 *) Reset timeout while reading via get_client_block() in mod_cgi.c
11933 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
11935 *) Add the ability to pass different Makefile.tmpl files to Configure
11936 using the -make flag. [Rob Hartill]
11938 *) Fix coredump triggered when sending a SIGHUP to the server caused
11939 by an assertion failure, in turn caused by an uninitialised field in a
11943 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
11944 PATH_INFO from previous versions of Apache (in certain situations,
11945 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
11946 [later removed in 1.2b11]
11948 *) Add rwrite() function to API to allow for sending strings of
11949 arbitrary length. [Doug MacEachern]
11951 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
11953 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
11954 NeXT. [Jim Jagielski]
11956 *) Removed recent modification to promote the status code on internal
11957 redirects, since the correct fix was to change the default log format
11958 in mod_log_config so that it outputs the original status. [Rob Hartill]
11960 Changes with Apache 1.2b2:
11962 *) Update set_signals() to use sigaction() for setting handlers.
11963 This appears to fix a re-entrant problem in the seg_fault()
11964 bus_error() handlers. [Randy Terbush]
11966 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
11968 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
11970 *) proxy_http.c bugfixes: [Chuck Murcko]
11971 1) fixes possible NULL pointer reference w/NoCache
11972 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
11973 host would cache nothing if it was in the local domain,
11974 and the local domain was in the NoCache list)
11975 3) Adds Host: header when not available
11976 4) Some code cleanup and clarification
11978 *) mod_include.c bugfixes:
11979 1) Fixed an ommission that caused include variables to not
11980 be parsed in config errmsg directives [Howard Fear]
11981 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
11982 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
11983 4) Allow backslash-escaping to all quoted text
11984 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
11985 5) Pass variable to command line if not set in XSSI's env
11988 *) Fix infinite loop when processing Content-language lines in
11989 type-map files. [Alexei Kosut]
11991 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
11993 *) Fixed problem in set_[user|group] that prevented CGI execution
11994 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
11996 *) Added PORTING information file. [Jim Jagielski]
11998 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
12000 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
12002 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
12003 USE_FCNTL_SERIALIZED_ACCEPT was intended.
12005 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
12006 which caused problems of systems where socket s_addr is >32bits.
12008 *) Added comment to explain (r->chunked = 1) side-effect in
12009 http_protocol.c [Roy Fielding]
12011 *) Replaced use of index() in mod_expires.c with more appropriate
12012 and portable isdigit() test. [Ben Laurie]
12014 *) Updated Configure for ...
12015 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
12016 *-dg-dgux* (bad pattern match)
12017 QNX (DEF_WANTHSREGEX=yes)
12018 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
12020 *-unixware211 (new)
12021 and added some user diagnostic info. [Ben Laurie]
12023 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
12024 for better portability. [Jim Jagielski]
12026 *) Updated helpers/GuessOS for ...
12027 SCO 5 (recognize minor releases)
12028 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
12029 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
12030 IRIX64 (-sgi-irix64)
12031 ULTRIX (-unknown-ultrix)
12032 SINIX (-whatever-sysv4)
12033 NCR Unix (-ncr-sysv4)
12034 and fixed something in helpers/PrintPath [Ben Laurie]
12036 Changes with Apache 1.2b1
12038 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
12040 Changes with Apache 1.1.1
12042 *) Fixed bug where Cookie module would make two entries in the
12043 logfile for each access [Mark Cox]
12045 *) Fixed bug where Redirect in .htaccess files would cause memory
12046 leak. [Nathan Neulinger]
12048 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
12050 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
12052 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
12054 Changes with Apache 1.1.0
12056 *) Bring NeXT support up to date. [Takaaki Matsumoto]
12058 *) Bring QNX support up to date. [Ben Laurie]
12060 *) Make virtual hosts default to main server keepalive parameters.
12061 [Alexei Kosut, Ben Laurie]
12063 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
12065 *) Fix missing address family for connect, also remove unreachable statement
12066 in mod_proxy. [Ben Laurie]
12068 *) mod_env now turned on by default in Configuration.tmpl.
12070 *) Bugs which were fixed:
12071 a) yet more mod_proxy bugs [Ben Laurie]
12072 b) CGI works again with inetd [Alexei Kosut]
12073 c) Leading colons were stripped from passwords [osm@interguide.com]
12074 d) Another fix to multi-method Limit problem [jk@tools.de]
12076 Changes with Apache 1.1b4
12078 *) r->bytes_sent variable restored. [Robert Thau]
12080 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
12082 *) More possibly unsecure programs removed from the support directory.
12084 *) More mod_auth_msql authentication improvements.
12086 *) VirtualHosts based on Host: headers no longer conflict with the
12089 *) OS/2 compatibility enhancements. [Gary Smiley]
12091 *) POST now allowed to directory index CGI scripts.
12093 *) Actions now work with files of the default type.
12095 *) Bugs which were fixed:
12096 a) more mod_proxy bugs
12097 b) early termination of inetd requests
12098 c) compile warnings on several systems
12099 d) problems when scripts stop reading output early
12101 Changes with Apache 1.1b3
12103 *) Much of cgi-bin and all of cgi-src has been removed, due to
12104 various security holes found and that we could no longer support
12107 *) The "Set-Cookie" header is now special-cased to not merge multiple
12108 instances, since certain popular browsers can not handle multiple
12109 Set-Cookie instructions in a single header. [Paul Sutton]
12111 *) rprintf() added to buffer code, occurrences of sprintf removed.
12114 *) CONNECT method for proxy module, which means tunneling SSL should work.
12115 (No crypto needed) Also a NoCache config directive.
12117 *) Several API additions: pstrndup(), table_unset() and get_token()
12118 functions now available to modules.
12120 *) mod_imap fixups, in particular Location: headers are now complete
12123 *) New "info" module which reports on installed module set through a
12124 special URL, a la mod_status.
12126 *) "ServerPath" directive added - allows for graceful transition
12127 for Host:-header-based virtual hosts.
12129 *) Anonymous authentication module improvements.
12131 *) MSQL authentication module improvements.
12133 *) Status module design improved - output now table-based. [Ben Laurie]
12135 *) htdigest utility included for use with digest authentication
12138 *) mod_negotiation: Accept values with wildcards to be treated with
12139 less priority than those without wildcards at the same quality
12140 value. [Alexei Kosut]
12142 *) Bugs which were fixed:
12143 a) numerous mod_proxy bugs
12144 b) CGI early-termination bug [Ben Laurie]
12145 c) Keepalives not working with virtual hosts
12146 d) RefererIgnore problems
12147 e) closing fd's twice in mod_include (causing core dumps on
12148 Linux and elsewhere).
12150 Changes with Apache 1.1b2
12153 a) core dumps in mod_digest
12154 b) truncated hostnames/ip address in the logs
12155 c) relative URL's in mod_imap map files
12157 Changes with Apache 1.1b1
12159 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12161 Changes with Apache 1.0.3
12163 *) Internal redirects which occur in mod_dir.c now preserve the
12164 query portion of a request (the bit after the question mark).
12167 *) Escape active characters '<', '>' and '&' in html output in
12168 directory listings, error messages and redirection links.
12171 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12173 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12176 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12178 *) Reset timeout timer after each successful fwrite() to the network.
12179 This patch adds a reset_timeout() procedure that is called by
12180 send_fd() to reset the timeout ever time data is written to the net.
12183 *) timeout() signal handler now checks for SIGPIPE and reports
12184 lost connections in a more user friendly way. [Rob Hartill]
12186 *) Location of the "scoreboard" file which used to live in /tmp is
12187 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12188 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12190 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12192 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12193 which caused a SEGV with cookies enabled
12195 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12198 *) Log the UNIX textual error returned by some system calls, in
12199 particular errors from accept() [David Robinson]
12201 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12203 Changes with Apache 1.0.2
12205 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12206 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12208 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12211 *) past changes to http_config.c to only use the
12212 setrlimit function on systems defining RLIMIT_NOFILE
12213 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12214 for SUNOS and prototypes the needed functions.
12216 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12219 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12221 *) Merge multiple headers from CGI scripts instead of taking last
12222 one. [David Robinson]
12224 *) Add support for SCO 5. [Ben Laurie]
12226 Changes with Apache 1.0.1
12228 *) Silence mod_log_referer and mod_log_agent if not configured
12231 *) Recursive includes can occur if the client supplies PATH_INFO data
12232 and the server provider uses relative links; as file.html
12233 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
12235 *) The replacement for initgroups() did not call {set,end}grent(). This
12236 had two implications: if anything else used getgrent(), then
12237 initgroups() would fail, and it was consuming a file descriptor.
12240 *) On heavily loaded servers it was possible for the scoreboard to get
12241 out of sync with reality, as a result of a race condition.
12242 The observed symptoms are far more Apaches running than should
12243 be, and heavy system loads, generally followed by catastrophic
12244 system failure. [Ben Laurie]
12246 *) Fix typo in license. [David Robinson]
12248 Changes with Apache 1.0.0 23 Nov 1995
12250 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
12252 Changes with Apache 0.8.16 05 Nov 1995
12254 *) New man page for 'httpd' added to support directory [David Robinson]
12256 *) .htgroup files can have more than one line giving members for a
12257 given group (each must have the group name in front), for NCSA
12258 back-compatibility [Robert Thau]
12260 *) Mutual exclusion around accept() is on by default for SVR4 systems
12261 generally, since they generally can't handle multiple processes in
12262 accept() on the same socket. This should cure flaky behavior on
12263 a lot of those systems. [David Robinson]
12265 *) AddType, AddEncoding, and AddLanguage directives take multiple
12266 extensions on a single command line [David Robinson]
12268 *) UserDir can be disabled for a given virtual host by saying
12269 "UserDir disabled" in the <VirtualHost> section --- it was a bug
12270 that this didn't work. [David Robinson]
12272 *) Compiles on QNX [Ben Laurie]
12274 *) Corrected parsing of ctime time format [David Robinson]
12276 *) httpd does a perror() before exiting if it can't log its pid
12277 to the PidFile, to make diagnosing the error a bit easier.
12280 *) <!--#include file="..."--> can no longer include files in the
12281 parent directory, for NCSA back-compatibility. [David Robinson]
12283 *) '~' is *not* escaped in URIs generated for directory listings
12286 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
12288 *) Fixed bug involving handling URIs with escaped %-characters
12289 in redirects [David Robinson]
12291 Changes with Apache 0.8.15 14 Oct 1995
12293 *) Switched to new, simpler license
12295 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
12297 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
12299 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
12301 *) Correctly handles internal redirects to files with names containing '%'
12304 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
12306 *) Use geteuid() rather than getuid() to see if we have root privilege,
12307 so that server correctly resets privilege if run setuid root. [Andrew
12310 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
12313 *) Fix relative URLs in imagemap files [Randy Terbush]
12315 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
12318 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
12319 entries all name the same one. [David Robinson]
12321 *) Fix directory listings with filenames containing unusual characters
12324 *) Better URI-escaping for generated URIs in directories with filenames
12325 containing unusual characters [Ben Laurie]
12327 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
12329 *) Unblock alarms on error return from spawn_child() [David Robinson]
12331 *) Sample Config files have extra note for SCO users [Ben Laurie]
12333 *) Configuration has note for HP-UX users [Rob Hartill]
12335 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
12337 *) Nuked bogus #define in httpd.h [David Robinson]
12339 *) Better test for whether a system has setrlimit() [David Robinson]
12341 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
12343 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
12346 Changes with Apache 0.8.14 19 Sep 1995
12348 *) Compiles on SCO ODT 3.0 [Ben Laurie]
12350 *) AddDescription works (better) [Ben Laurie]
12352 *) Leaves an intelligible error diagnostic when it can't set group
12353 privileges on standalone startup [Andrew Wilson]
12355 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
12356 that machine, which claims to be BSD but does not support RLIMIT.
12359 *) gcc -Wall no longer complains about an unused variable when util.c
12360 is compiled with -DMINIMAL_DNS [Andrew Wilson]
12362 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
12364 Changes with Apache 0.8.13 07 Sep 1995
12366 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
12368 *) Have built-in imagemap code recognize & honor Point directive [James
12371 *) Generate cleaner directory listings in directories with a mix of
12372 long and short filenames [Rob Hartill]
12374 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
12376 *) Properly default ServerName for virtual servers [Robert Thau]
12378 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
12379 Paul Richards and a cast of thousands...]
12381 *) On self-identified BSD systems (we don't try to guess any more),
12382 allocate a few extra file descriptors per virtual host with setrlimit,
12383 if we can, to avoid running out. [Randy Terbush]
12385 *) Write 22-character lock file name into buffer with enough space
12386 on startup [Konstantin Olchanski]
12388 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
12391 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
12393 *) Suppress -Wall warning by initializing variable in negotiation code
12394 [Tobias Weingartner]
12396 Changes with Apache 0.8.12 31 Aug 1995
12398 *) Doesn't pause three seconds after including a CGI script which is
12399 too slow to die off (this is done by not even trying to kill off
12400 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
12401 after the entire document has been processed). [Robert Thau]
12403 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
12405 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
12407 *) Allows .htaccess files to override <Directory> sections naming the
12408 same directory [David Robinson]
12410 *) Removed an efficiency hack in sub_req_lookup_uri which was
12411 causing certain extremely marginal cases (e.g., ScriptAlias of a
12412 *particular* index.html file) to fail. [David Robinson]
12414 *) Doesn't log an error when the requested URI requires
12415 authentication, but no auth header line was supplied by the
12416 client; this is a normal condition (the client doesn't no auth is
12417 needed here yet). [Robert Thau]
12419 *) Behaves more sanely when the name server loses its mind [Sean Welch]
12421 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
12423 *) RFC931 code no longer passes out name of prior clients on current
12424 requests if the current request came from a server that doesn't
12425 do RFC931. [David Robinson]
12427 *) Configuration script accepts "Module" lines with trailing whitespace.
12430 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
12432 *) Cleaned up comments in mod_cgi.c [Robert Thau]
12434 Changes with Apache 0.8.11 24 Aug 1995
12436 *) Wildcard <Directory> specifications work. [Robert Thau]
12438 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
12440 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
12441 the file being requested itself, in addition to the directories leading
12442 up to it. [Robert Thau]
12444 *) Logs access failures due to symlink checks or invalid client address
12445 in the error log [Roy Fielding, Robert Thau]
12447 *) Symlink checks deal correctly with systems where lstat of
12448 "/path/to/some/link/" follows the link. [Thau, Fielding]
12450 *) Doesn't reset DirectoryIndex to 'index.html' when
12451 other directory options are set in a .htaccess file. [Robert Thau]
12453 *) Clarified init code and nuked bogus warning in mod_access.c
12454 [Florent Guillaume]
12456 *) Corrected several directives in sample srm.conf
12457 --- includes corrections to directory indexing icon-related directives
12458 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
12459 icons for encodings right, and turning on AddEncoding by default).
12462 *) Corrected descriptions of args to AddIcon and AddAlt in command table
12465 *) INSTALL & README mention "contributed modules" directory [Brian
12468 *) Fixed English in the license language... "for for" --> "for".
12471 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
12472 mod_alias.c, merging it almost completely with handling of Alias, and
12473 adding a 'notes' field to the request_rec which allows the CGI module
12474 to discover whether the Alias module has put this request through
12475 ScriptAlias (which it needs to know for back-compatibility, as the old
12476 NCSA code did not check Options ExecCGI in ScriptAlias directories).
12479 Changes with Apache 0.8.10 18 Aug 1995
12481 *) AllowOverride applies to the named directory, and not just
12482 subdirectories. [David Robinson]
12484 *) Do locking for accept() exclusion (on systems that need it)
12485 using a special file created for the purpose in /usr/tmp, and
12486 not the error log; using the error log causes real problems
12487 if it's NFS-mounted; this is known to be the cause of a whole
12488 lot of "server hang" problems with Solaris. [David Robinson;
12489 thanks to Merten Schumann for help diagnosing the problem].
12491 Changes with Apache 0.8.9 12 Aug 1995
12493 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
12495 *) Nested includes see environment variables of the including document,
12496 for NCSA bug-compatibility (some sites have standard footer includes
12497 which try to print out the last-modified date). [Eric Hagberg/Robert
12500 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
12501 URI as a CGI script, even if it would have been treated as something
12502 else if requested directly, for NCSA back-compatibility. (Note that
12503 this means that people who know the name of the script can see the
12504 code just by asking for it). [Robert Thau]
12506 *) New version of dbmmanage script included in support directory as
12509 *) Check if scoreboard file couldn't be opened, and say so, rather
12510 then going insane [David Robinson]
12512 *) POST to CGI works on A/UX [Jim Jagielski]
12514 *) AddIcon and AddAlt commands work properly [Rob Hartill]
12516 *) NCSA server push works properly --- the Arena bug compatibility
12517 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
12518 if you still want the workaround). [Rob Hartill]
12520 *) If client didn't submit any Accept-encodings, ignore encodings in
12521 content negotiation. (NB this will all have to be reworked anyway
12522 for the new HTTP draft). [Florent Guillaume]
12524 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
12526 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
12528 *) Give Redirect priority over Alias, for NCSA bug compatibility
12531 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
12532 paralleling earlier bug fix for CGI [David Robinson]
12534 *) If DBM auth is improperly configured, report a server error and don't
12537 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
12538 it seems to work well enough without it (even in a 10 hits/sec
12539 workout), and the overhead for the locking under A/UX is
12540 alarmingly high (though it is very low on other systems).
12541 [Eric Hagberg, Jim Jagielski]
12543 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
12545 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
12546 Behlendorf/Eric Hagberg]
12548 *) More improvements to default Configuration for A/UX [Jim Jagielski]
12550 *) Compiles clean on NEXT [Rob Hartill]
12552 *) Compiles clean on SGI [Robert Thau]
12554 Changes with Apache 0.8.8 08 Aug 1995
12556 *) SunOS library prototypes now never included unless explicitly
12557 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
12558 people using GNU libc on SunOS are screwed by prototypes for the
12561 (Those who wish to compile clean with gcc -Wall on a standard
12562 SunOS setup need the prototypes, and may obtain them using
12563 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
12564 with nonstandard libraries are presumably competent to make their
12567 *) Strips trailing '/' characters off both args to the Alias command,
12568 to make 'Alias /foo/ /bar/' work.
12570 Changes with Apache 0.8.7 03 Aug 1995
12572 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
12573 [reported by David Robinson]
12575 *) Compiles clean on OSF/1 [David Robinson]
12577 *) Added some of the more recent significant changes (AddLanguage stuff,
12578 experimental LogFormat support) to CHANGES file in distribution root
12581 Changes with Apache 0.8.6 02 Aug 1995
12583 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
12584 (If you actually wanted a conditional GET which bypassed the cache, you
12585 couldn't get it). [Reported by Roy Fielding]
12587 *) Properly terminate headers on '304 Not Modified' replies to conditional
12588 GETs --- no browser we can find cares much, but the CERN proxy chokes.
12589 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
12591 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
12593 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
12594 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
12595 and older versions don't set the __SUNPRO_C preprocessor variable). On
12596 all other systems, these are never used anyway. [Reported by Mark Cox].
12598 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
12600 Changes with Apache 0.8.5 01 Aug 1995
12602 *) Added last-minute configurable log experiment, as optional module
12604 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
12605 properly. (One-line fix to http_protocol.c).
12607 *) Work around bogus behavior when reloading from Netscape.
12608 It's Netscape's bug --- for some reason they expect a request with
12609 If-modified-since: to not function as a conditional GET if it also
12610 comes with Pragma: no-cache, which is way out of line with the HTTP
12611 spec (according to Roy Fielding, the redactor).
12613 *) Added parameter to set maximum number of server processes.
12615 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
12618 *) IdentityCheck bugfix [Chuck Murcko].
12620 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
12622 *) More sample config file corrections; add extension to AddType for
12623 *.asis, move AddType generic description to its proper place, and
12624 fix miscellaneous typos. [ Alexei Kosut ]
12626 *) Deleted the *other* reference to the regents from the Berkeley
12627 legal disclaimer (everyplace).
12629 *) Nuked Shambhala name from src/README; had already cleaned it out
12630 of everywhere else.
12632 Changes with Apache 0.8.4
12634 *) Changes to server-pool management parms --- renamed current
12635 StartServers to MinSpareServers, created separate StartServers
12636 parameter which means what it says, and renamed MaxServers to
12637 MaxSpareServers (though the old name still works, for NCSA 1.4
12638 back-compatibility). The old names were generally regarded as
12639 too confusing. Also altered "docs" in sample config files.
12641 *) More improvements to default config files ---
12642 sample directives (commented out) for XBitHack, BindAddress,
12643 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
12644 defaults, AddTypes for send-as-is and imagemap magic types, and
12645 improvements to samples for DirectoryIndex [Alexei Kosut]
12647 *) Yet more improvements to default config files --- changes to
12648 Alexei's sample AddLanguage directives, and sample LanguagePriority
12649 [ Florent Guillaume ]
12651 *) Set config file locations properly if not set in httpd.conf
12654 *) Don't escape URIs in internal redirects multiple times; don't
12655 do that when translating PATH_INFO to PATH_TRANSLATED either.
12658 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
12660 Changes with Apache 0.8.3
12662 *) Edited distribution README to *briefly* summarize installation
12663 procedures, and give a pointer to the INSTALL file in the src/
12666 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
12667 recent NCSA distributions.
12669 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
12670 exist for the same directory, use both and don't segfault. [Reported
12673 *) Proper makefile dependencies [David Robinson]
12675 *) Note (re)starts in error log --- reported by Rob Hartill.
12677 *) Only call no2slash() after get_path_info() has been done, to
12678 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
12679 reported by Andrew Wilson, though this one is probably a real bug]
12681 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
12682 dump core when Referer is not supplied. [Randy Terbush]
12684 *) Lightly edited sample config files to refer people to our documentation
12685 instead of NCSA's, and to list Rob McCool as *original* author (also
12686 deleted his old, and no doubt non-functional email address). Would be
12687 nice to have examples of new features...
12689 Changes with Apache 0.8.2 19 Jul 1995
12691 *) Added AddLanuage code [Florent Guillaume]
12693 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
12695 *) All sorts of problems when MultiViews finds a directory. It would
12696 be nice if mod_dir.c was robust enough to handle that, but for now,
12697 just punt. [reported by Brian Behlendorf]
12699 *) Wait for all children on restart, to make sure that the old socket
12700 is gone and we can reopen it. [reported by Randy Terbush]
12702 *) Imagemap module is enabled in default Configuration
12704 *) RefererLog and UserAgentLog modules properly default the logfile
12707 *) Mark Cox's mod_cookies added to the distribution as an optional
12708 module (commented out in the default Configuration, and noted as
12709 an experiment, along with mod_dld). [Mark Cox]
12711 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
12713 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
12715 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
12717 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
12720 Changes with Apache 0.8.1
12722 *) New imagemap module [Randy Terbush]
12724 *) Replacement referer log module with NCSA-compatible RefererIgnore
12725 [Matthew Gray again]
12727 *) Don't mung directory listings with very long filenames.
12728 [Florent Guillaume]
12730 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
12732 *) New config script. See INSTALL for info. [Robert Thau]
12734 *) Scoreboard mechanism for regulating the number of extant server
12735 processes. MaxServers and StartServers defaults are the same as
12736 for NCSA, but the meanings are slightly different. (Actually,
12737 I should probably lower the MaxServers default to 10).
12739 Before asking for a new connection, each server process checks
12740 the number of other servers which are also waiting for a
12741 connection. If there are more than MaxServers, it quietly dies
12742 off. Conversely, every second, the root, or caretaker, process
12743 looks to see how many servers are waiting for a new connection;
12744 if there are fewer than StartServers, it starts a new one. This
12745 does not depend on the number of server processes already extant.
12746 The accounting is arranged through a "scoreboard" file, named
12747 /tmp/htstatus.*, on which each process has an independent file
12748 descriptor (they need to seek without interference).
12750 The end effect is that MaxServers is the maximum number of
12751 servers on an *inactive* server machine, but more will be forked
12752 off to handle unusually heavy loads (or unusually slow clients);
12753 these will die off when they are no longer needed --- without
12754 reverting to the overhead of full forking operation. There is a
12755 hard maximum of 150 server processes compiled in, largely to
12756 avoid forking out of control and dragging the machine down.
12757 (This is arguably too high).
12759 In my server endurance tests, this mechanism did not appear to
12760 impose any significant overhead, even after I forced it to put the
12761 scoreboard file on a normal filesystem (which might have more
12762 overhead than tmpfs). [Robert Thau]
12764 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
12767 *) Read .htaccess files even in directory with <Directory> section.
12768 (Former incompatibility noted on mailing list, now fixed). [Robert
12771 *) "HEAD /" gives the client a "Bad Request" error message, rather
12772 than trying to send no body *and* no headers. [Cliff Skolnick].
12774 *) Don't produce double error reports for some very obscure cases
12775 mainly involving auth configuration (the "all modules decline to
12776 handle" case which is a sure sign of a server bug in most cases,
12777 but also happens when authentication is badly misconfigured).
12780 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
12781 it's *for*, and this sort of thing really shouldn't be cluttering
12782 up the Makefile). [Robert Thau]
12784 *) Incidental code cleanups in http_main.c --- stop dragging
12785 sa_client around; just declare it where used. [Robert Thau]
12787 *) Another acc-related fix. (It doesn't like const char
12788 in some places...). [Mark Cox]
12790 Changes with Shambhala 0.6.1 13 Jul 1995
12792 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
12793 Also, fixed auth typo in http_protocol.c unmasked by this fix.
12795 *) Compiles clean with acc on SunOS [Paul Sutton]
12797 *) Reordered modules in modules.c so that Redirect takes priority
12798 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
12799 believe it or not, he has an actual site with a ScriptAlias and
12800 a Redirect declared for the *exact same directory*. Even *my*
12801 compatibility fetish wouldn't motivate me to fix this if the fix
12802 required any effort, but it doesn't, so what the hey.
12804 *) Fixed to properly default several server_rec fields for virtual
12805 servers from the corresponding fields in the main server_rec.
12806 [Cliff Skolnick --- 'port' was a particular irritant].
12808 *) No longer kills off nph- child processes before they are
12809 finished sending output. [Matthew Gray]
12811 Changes with Shambhala 0.6.0 10 Jul 1995
12813 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
12814 the connection to the client in an "aborted" state, but otherwise
12815 allow whatever handlers are running to clean up. hard_timeout()s
12816 abort the request in progress completely; anything not tied to some
12817 resource pool cleanup will leak. They're still around because I
12818 haven't yet come up with a more elegant way of handling
12819 timeouts when talking to something that isn't the client. The
12820 default_handler and the dir_handler now use soft timeouts, largely
12821 so I can test the feature. [Robert Thau]
12823 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
12824 the case of log handlers dying prematurely is probably handled VERY
12825 gracelessly at this point, and if the logger stops reading input,
12826 the server will hang. (It is known to correctly restart the
12827 logging process on server restart; this is (should be!) going through
12828 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
12829 script). [Robert Thau]
12831 *) asis files supported (new module). [Robert Thau]
12833 *) IdentityCheck code is compiled in, but has not been tested. (I
12834 don't know anyone who runs identd). [Robert Thau]
12836 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
12837 came in with the request, for NCSA bug-compatibility. [Robert Thau]
12839 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
12841 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
12842 as timeouts are not in scope. [Robert Thau]
12844 *) quoted-string args in config files now handled correctly (doesn't drop
12845 the last character). [Robert Thau; reported by Randy Terbush]
12847 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
12848 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
12850 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
12851 default default type); the former default default behavior when all
12852 type-checkers defaulted had been a core dump. [Paul Sutton]
12854 *) Copy filenames out of the struct dirent when indexing
12855 directories. (On Linux, readdir() returns a pointer to the same
12856 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
12858 Changes with Shambhala 0.5.3 [not released]
12860 *) Default response handler notes "file not found" in the error log,
12861 if the file was not found. [Cliff Skolnick].
12863 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
12864 code no longer sets up bogus PATH_INFO which fakes out the directory
12865 handler). [Cliff Skolnick]
12867 Changes with Shambhala 0.5.2 06 Jul 1995
12869 *) Changes to http_main.c --- root server no longer plays silly
12870 games with SIGCHLD, and so now detects and replaces dying
12871 children. Child processes just die on SIGTERM, without taking
12872 the whole process group with them. Potential problem --- if any
12873 child process refuses to die, we hang in restart.
12874 MaxRequestsPerChild may still not work, but it certainly works
12875 better than it did before this! [Robert Thau]
12877 *) mod_dir.c bug fixes: ReadmeName and HeaderName
12878 work (or work better, at least); over-long description lines
12879 properly terminated. [Mark Cox]
12881 *) http_request.c now calls unescape_url() more places where it
12882 should [Paul Sutton].
12884 *) More directory handling bugs (reported by Cox)
12885 Parent Directory link is now set correctly. [Robert Thau]
12887 Changes with Shambhala 0.5.1 04 Jul 1995
12889 *) Generalized cleanup interface in alloc.c --- any function can be
12890 registered with alloc.c as a cleanup for a resource pool;
12891 tracking of files and file descriptors has been reimplemented in
12892 terms of this interface, so I can give it some sort of a test.
12895 *) More changes in alloc.c --- new cleanup_for_exec() function,
12896 which tracks down and closes all file descriptors which have been
12897 registered with the alloc.c machinery before the server exec()s a
12898 child process for CGI or <!--#exec-->. CGI children now get
12899 started with exactly three file descriptors open. Hopefully,
12900 this cures the problem Rob H. was having with overly persistent
12901 CGI connections. [Robert Thau]
12903 *) Mutual exclusion around the accept() in child_main() --- this is
12904 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
12905 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
12906 This uses fcntl(F_SETLK,...) on the error log descriptor because
12907 flock() on that descriptor won't work on systems which have BSD
12908 flock() semantics, including (I think) Linux 1.3 and Solaris.
12910 This does work on SunOS (when the server is idle, only one
12911 process in the pool is waiting on accept()); it *ought* to work
12912 on the other systems. [Robert Thau]
12914 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
12916 *) sizeof(*sa_client) bugfix from [Rob Hartill]
12918 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
12920 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
12921 be unnecessary if I go to the revised timeout-handling scheme).
12924 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
12925 string) even if none came in with the request. [Robert Thau]
12927 *) CHANGES file added to distribution ;-).
12929 Changes with Shambhala 0.4.5
12931 *) mod_dld --- early dynamic loading support [rst]
12932 *) Add wildcard content handlers for XBITHACK; default_hander now
12933 invoked with that mechanism (as a handler hanging off mod_core) [rst]
12934 *) XBITHACK supported as a wildcard content-handler, and
12935 configurable at run-time (not just at compile time, as in the
12936 "patchy server" releases) [rst]
12938 Changes with Shambhala 0.4.4 30 Jun 1995
12940 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
12941 *) Handle Addtype x/y .z [rst, reported by Cox]
12943 Changes with Shambhala 0.4.3
12945 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
12946 synonymous [rst, terbush]
12948 Changes with Shambhala 0.4.1 28 Jun 1995
12950 *) First-cut virtual host implementation; some refit in the config
12951 reading code, and log management, was necessary to support this [rst]
12952 *) Sub-pool machinery, originally added to avoid excessive storage
12953 allocation on listings of large directories (which turned out to
12954 be the problem that the 0.3 storage accounting was added to
12955 find). Subrequests and mod_dir changed to use subpools. [rst]
12956 *) More memory debugging --- free list consistency checks. [rst]
12957 *) Added err_headers to request_rec, with support elsewhere [rst]
12958 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
12960 Changes with Shambhala 0.3 19 Jun 1995
12962 *) Switch ONE_PROCESS to a runtime command-line option (-X)
12963 *) Don't compile in mod_ai_backcompat by default
12964 *) Switch name of server from Apache to Shambhala in Makefile
12965 *) Add some accounting routines to track memory usage in the pools,
12968 Changes with Shambhala 0.2
12970 *) Set DOCUMENT_ROOT CGI variable
12971 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
12972 *) Add critical section protection to handling of cleanup structures
12974 *) Significant code reorg within the server core to group related
12975 functions together [rst]
12976 *) Correctly handle clients that hang up before sending any request
12978 *) Replace dying child processes. [rst]
12980 Changes with Shambhala 0.1 12 Jun 1995
12982 Major rewrite of the pre-existing "patchy server" codebase, by
12983 Robert Thau (rst). Significant portions of the server code, such
12984 as configuration-file handling and HTTP authentication support,
12985 were ripped out and rewritten from scratch. Code that was not
12986 completely rewritten was significantly altered.
12988 Major changes with this release include:
12990 *) Introduction of the module API; in request handling, the central
12991 machinery just dispatches to various modules, which actually do
12992 most of the work. Configuration handling is similar --- modules
12993 declare their own commands, and the central machinery just
12994 dispatches to them.
12996 API features from shambhala/0.1 were substantially unchanged in
12997 Apache 1.0 and 1.1. (1.0 API features not yet present in this
12998 release, such as wildcard handlers and subpools, were added in
12999 subsequent Shambhala releases, and were also generally rst's
13002 *) This release included the following modules:
13004 mod_access (access control --- allow and deny directives),
13005 mod_alias (Alias and Redirect commands),
13006 mod_auth (straight HTTP authentication, based on flat-files)
13007 mod_auth_dbm (same, with dbm files)
13008 mod_cgi (CGI scripts and, in this release, ScriptAlias)
13009 mod_common_log (CLF access logs; later renamed mod_log_common)
13010 mod_dir (directory indexing)
13011 mod_include (server-side includes)
13012 mod_mime (AddType directives)
13013 mod_negotiation (content negotiation)
13014 mod_userdir (support for users' public_html directories)
13016 It also included a mod_ai_backcompat, which was a private hack
13017 for back-compatibility with rst's own AI-lab servers.
13019 All of these modules were substantially complete, and functional
13020 or nearly so (a few, which implemented features not in use at
13021 Thau's site, required patches of a few lines).
13023 *) sub-request machinery, to allow modules to determine how other
13024 modules would assign MIME types to a given file, or optionally
13025 serve its content (this is heavily used by mod_dir, mod_include
13026 and mod_negotiation).
13028 *) Resource pool system for keeping track of memory allocated and
13029 files opened in service of a particular request. Much of the
13030 code in the modules (when they weren't rewrites) was adjusted to
13031 replace a pervasive convention of using fixed-size buffers on
13032 the stack with an equally pervasive convention of using memory
13033 allocated with palloc().
13035 *) Reorganization of data structures associated with a given
13036 request to eliminate use of global variables and the troublesome
13037 unmunge_name function (used in NCSA and early Apache releases to
13038 attempt to determine the URI which mapped to a given filename
13039 --- a difficult proposition, given that it is easy to produce
13040 setups in which multiple URIs map to the same file).
13042 *) Source files renamed and rearranged
13044 *) Very simple pre-forking behavior --- parent process forked off a
13045 fixed number of children, and then just waited for SIGHUP.
13047 *) Other more minor changes too numerous to list.
13049 This release included modified versions of a lot of code from the
13050 Apache 0.6.4 public release, plus an early pre-forking patch
13051 codeveloped by Robert Thau and Rob Hartill.
13053 Changes with Apache 0.7.3 20 Jun 1995
13055 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
13056 were incorporated by Rob Hartill on the main branch while Robert Thau
13057 worked on the Shambhala rewrite above. Most were merged into the
13058 Shambala architecture after Apache 0.8.0.
13060 Changes with Apache 0.6.4 13 May 1995
13062 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
13065 Changes with Apache 0.5.1 10 Apr 1995
13067 Changes with Apache 0.4 02 Apr 1995

13072 Changes with Apache 0.3 24 Mar 1995
13074 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
13077 Changes with Apache 0.2 18 Mar 1995
13079 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
13080 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
13081 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
