12 containing the .htaccess file is requested without a trailing slash.
13 PR 20195. [André Malo]
15 *) mod_autoindex: If a directory contains a file listed in the
16 DirectoryIndex directive, the folder icon is no longer replaced
17 by the icon of that file. PR 9587.
18 [David Shane Holden <dpejesh@yahoo.com>]
20 *) mod_authz_groupfile: Strip trailing spaces of group names. This
21 hopefully saves some hours of searching for typos. PR 12863.

35 [Updated and reviewed by: Paul J. Reder]
37 *) mod_actions: Propagate the handler name to the action script via
38 the REDIRECT_HANDLER environment variable. [André Malo]
40 *) mod_actions: Introduce the "virtual" modifier to the Action directive,
41 which allows the use of handlers for virtual locations. PR 8431.
44 *) mod_speling: Recognize AcceptPathInfo setting for the particular

72 to using the expanded config variables to work the same as
73 httpd-std.conf PR 19611
76 *) Fix a problem with namespace mappings being dropped in mod_dav_fs;
77 if any property values were set which defined namespaces these
78 came out mangled in the PROPFIND response. PR 11637.
79 [Amit Athavale <amit_athavale@persistent.co.in>]
81 *) prefork MPM: Use the right permissions for the directory created
82 for gprof support. [Jim Carlson <jcarlson@jnous.com>]
84 *) Fix the inability to log errors like exec failure in
85 mod_ext_filter/mod_cgi script children. This was broken after
86 such children stopped inheriting the error log handle.
89 *) Fix a compile failure with recent OpenSSL and picky compilers
90 (e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
92 *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
93 the INCLUDE path to be defined properly.
94 PR 11310. [Geoff Thrope <geoff@geoffthorpe.net>]
96 *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
98 *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using

100 [Geoff Thorpe <geoff@geoffthorpe.net>]
102 *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
103 [Ian Holsman, André Malo]
105 *) mod_negotiation: quality values are now parsed independent from
106 the current locale. level values are now really parsed as integers.
107 PR 17564. [André Malo]
109 *) Added the WindowsSocketsWorkaround directive for Windows NT/2000/XP
110 to work around problems with certain VPN and Firewall products that
111 have buggy AcceptEx implementations.
112 [Allan Edwards w/ suggestions from Bill Stoddard & Bill Rowe]
114 *) Extend mod_negotiation to evaluate the environment variables
115 no-gzip and gzip-only-text/html the same way as mod_deflate does.
118 *) mod_rewrite: Fix some problems reporting errors with mapping
119 programs (RewriteMap prg:/something). [Jeff Trawick]
121 *) Return 413 if chunk-ext-header is too long rather than reading from
122 the truncated line. PR 15857. [Justin Erenkrantz]
124 *) Allow restart of httpd to occur even with syntax errors in the config
125 file. PR 16813. [Justin Erenkrantz]

133 *) Allow apachectl to perform status with links and elinks as well.
136 *) Extend the SetEnvIf directive to capture subexpressions of the
137 matched value. [André Malo]
139 *) mod_log_config change optional hook to return previous handler
142 *) Forward port of mod_actions' ability to handle arbitrary methods
143 with the Script directive. [André Malo]
145 *) Let suexec send a message to stderr, if it failed or its policy
146 was violated. This message appears in the error log and allows
147 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
149 *) Modify buildconf to copy all required files into httpd's tree.
150 [Thom May <thom@planetarytramp.net>]
152 *) Allow mod_dav to do weak entity comparison functions.
155 *) Move RFC 1413 ident requests from core to new module mod_ident.
158 *) Add mod_authz_owner - a forward port of "Require file-owner"
159 and "Require file-group", which was already present in version
162 *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
165 *) Replace some of the mutex locking in the worker MPM with
166 atomic operations for higher concurrency. [Brian Pane]
168 *) Allow 'make depend' to work with non-GCC compilers.
171 *) If an httpd.conf has commented out AddModule directives,
172 apxs -i -a will add an un-commented AddModule directive for
173 the new module, which breaks the config.
174 PR: 11212 [Joe Orton]
176 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
178 *) Move the check of the Expect request header field after the hook
179 for ap_post_read_request, since that is the only opportunity for
180 modules to handle Expect extensions. [Justin Erenkrantz]
182 *) Rewrite of aaa modules to an authn/authz model.
183 [Dirk-Willem van Gulik, Justin Erenkrantz]
186 [Apache 2.1.0-dev includes those bug fixes and changes with the
187 Apache 2.0.xx tree as documented, and except as noted, below.]
189 Changes with Apache 2.0.48
191 *) mod_deflate: Don't attempt to hold all of the response until we're
192 done. [Justin Erenkrantz]
194 *) Assure that we block properly when reading input bodies with SSL.
195 PR 19242. [David Deaves <David.Deaves@dd.id.au>, William Rowe]
197 *) Update mime.types to include latest IANA and W3C types. [Roy Fielding]
199 *) mod_ext_filter: Set additional environment variables for use by
200 the external filter. PR 20944. [Andrew Ho, Jeff Trawick]
202 *) Fix buildconf errors when libtool version changes. [Jeff Trawick]
204 *) Remember an authenticated user during internal redirects if the
205 redirection target is not access protected and pass it
206 to scripts using the REDIRECT_REMOTE_USER environment variable.
207 PR 10678, 11602. [André Malo]
209 *) mod_include: Fix a trio of bugs that would cause various unusual
210 sequences of parsed bytes to omit portions of the output stream.
211 PR 21095. [Ron Park <ronald.park@cnet.com>, André Malo, Cliff Woolley]
213 *) Update the header token parsing code to allow LWS between the
214 token word and the ':' seperator. [PR 16520]
215 [Kris Verbeeck <kris.verbeeck@advalvas.be>,Nicel KM <mnicel@yahoo.com>]
217 *) Eliminate creation of a temporary table in ap_get_mime_headers_core()
218 [Joe Schaefer <joe+gmane@sunstarsys.com>]
220 *) Added FreeBSD directory layout. PR 21100.
221 [Sander Holthaus <info@orangexl.com>, André Malo]
223 *) Fix NULL-pointer issue in ab when parsing an incomplete or non-HTTP
224 response. PR 21085. [Glenn Nielsen <glenn@apache.org>, André Malo]
226 *) mod_rewrite: Perform child initialization on the rewrite log lock.
227 This fixes a log corruption issue when flock-based serialization
228 is used (e.g., FreeBSD). [Jeff Trawick]
230 *) Don't respect the Server header field as set by modules and CGIs.
231 As with 1.3, for proxy requests any such field is from the origin
232 server; otherwise it will have our server info as controlled by
233 the ServerTokens directive. [Jeff Trawick]
235 Changes with Apache 2.0.47
237 *) SECURITY [CAN-2003-0192]: Fixed a bug whereby certain sequences
238 of per-directory renegotiations and the SSLCipherSuite directive
239 being used to upgrade from a weak ciphersuite to a strong one
240 could result in the weak ciphersuite being used in place of the
241 strong one. [Ben Laurie]
243 *) SECURITY [CAN-2003-0253]: Fixed a bug in prefork MPM causing
244 temporary denial of service when accept() on a rarely accessed port
245 returns certain errors. Reported by Saheed Akhtar
246 <S.Akhtar@talis.com>. [Jeff Trawick]
248 *) SECURITY [CAN-2003-0254]: Fixed a bug in ftp proxy causing denial
249 of service when target host is IPv6 but proxy server can't create
250 IPv6 socket. Fixed by the reporter. [Yoshioka Tsuneo
251 <tsuneo.yoshioka@f-secure.com>]
253 *) SECURITY [VU#379828] Prevent the server from crashing when entering
254 infinite loops. The new LimitInternalRecursion directive configures
255 limits of subsequent internal redirects and nested subrequests, after
256 which the request will be aborted. PR 19753 (and probably others).
257 [William Rowe, Jeff Trawick, André Malo]
259 *) core_output_filter: don't split the brigade after a FLUSH bucket if
260 it's the last bucket. This prevents creating unneccessary empty
261 brigades which may not be destroyed until the end of a keepalive
263 [Juan Rivera <Juan.Rivera@citrix.com>]
265 *) Add support for "streamy" PROPFIND responses.
266 [Ben Collins-Sussman <sussman@collab.net>]
268 *) mod_cgid: Eliminate a double-close of a socket. This resolves
269 various operational problems in a threaded MPM, since on the
270 second attempt to close the socket, the same descriptor was
271 often already in use by another thread for another purpose.
274 *) mod_negotiation: Introduce "prefer-language" environment variable,
275 which allows to influence the negotiation process on request basis
276 to prefer a certain language. [André Malo]
278 *) Make mod_expires' ExpiresByType work properly, including for
279 dynamically-generated documents. [Ken Coar, Bill Stoddard]
281 Changes with Apache 2.0.46
283 *) SECURITY [CAN-2003-0245]: Fixed a bug causing apr_pvsprintf() to crash
284 by sending an overly long string. This can be triggered remotely
285 through mod_dav, mod_ssl, and other mechanisms. Reported by David
286 Endler <DEndler@iDefense.com>.
287 [Joe Orton <jorton@redhat.com>]
289 *) SECURITY [CAN-2003-0189]: Fixed a denial-of-service vulnerability
290 affecting basic authentication on Unix platforms related to
291 thread-safety in apr_password_validate(). The problem was reported
292 by John Hughes <john.hughes@entegrity.com>.
294 *) Fix for mod_dav. Call the 'can_be_activity' callback, if provided,
295 when a MKACTIVITY request comes in.
296 [Ben Collins-Sussman <sussman@collab.net>]
298 *) Perform run-time query in apxs for apr and apr-util's includes.
301 *) run libtool from the apr install directory (in case that is different
302 from the apache install directory) [Jeff Trawick]
304 *) configure.in: Play nice with libtool-1.5. [Wilfredo Sanchez]
306 *) If mod_mime_magic does not know the content-type, do not attempt to
307 guess. PR 16908. [Andrew Gapon <agapon@telcordia.com>]
309 *) ssl session caching(shmht) : Fix a SEGV problem with SHMHT session
311 [Andreas Leimbacher <andreasl67@yahoo.de>, Madhusudan Mathihalli]
313 *) Add a delete flag to htpasswd.
316 *) Fix mod_rewrite's handling of absolute URIs. The escaping routines
317 now work scheme dependent and the query string will only be
318 appended if supported by the particular scheme. [André Malo]
320 *) Add another check for already compressed content in mod_deflate.
321 PR 19913. [Tsuyoshi SASAMOTO <nazonazo@super.win.ne.jp>]
323 *) Fixes for VPATH builds; copying special.mk and any future .mk files
324 from the source tree as well as the build tree (now creates a usable
325 configuration for apxs), and eliminated redundant -I'nclude paths.
328 *) Code fixes, constness corrections and ssl_toolkit_compat.h updates
329 for SSLC and OpenSSL toolkit compatibility. Still work remains to
330 be done to cripple features based on the limitations of RSA's binary
331 distribution of their SSL-C toolkit.
332 [William Rowe, Madhusudan Mathihalli, Jeff Trawick]
334 *) Linux 2.4+: If Apache is started as root and you code
335 CoreDumpDirectory, coredumps are enabled via the prctl() syscall.
338 *) ap_get_mime_headers_core: allocate space for the trailing null
339 when folding is in effect.
340 PR 18170 [Peter Mayne <PeterMayne@SPAM_SUX.ap.spherion.com>]
342 *) Fix --enable-mods-shared=most and other variants. [Aaron Bannert]
344 *) mod_log_config: Add the ability to log the id of the thread
345 processing the request via new %P formats. [Jeff Trawick]
347 *) Use appropriate language codes for Czech (cs) and Traditional Chinese
348 (zh-tw) in default config files. PR 9427. [André Malo]
350 *) mod_auth_ldap: Use generic whitespace character class when parsing
351 "require" directives, instead of literal spaces only. PR 17135.
354 *) Hook mod_rewrite's type checker before mod_mime's one. That way the
355 RewriteRule [T=...] Flag should work as expected now. PR 19626.
358 *) htpasswd: Check the processed file on validity. If a line is not empty
359 and not a comment, it must contain at least one colon. Otherwise exit
360 with error code 7. [Kris Verbeeck <Kris.Verbeeck@ubizen.com>, Thom May]
362 *) Fix a problem that caused httpd to be linked with incorrect flags
363 on some platforms when mod_so was enabled by default, breaking
364 DSOs on AIX. PR 19012 [Jeff Trawick]
366 *) By default, use the same CC and CPP with which APR was built.
367 The user can override with CC and CPP environment variables.
370 *) Fix ap_construct_url() so that it surrounds IPv6 literal address
371 strings with []. This fixes certain types of redirection.
372 PR 19207. [Jeff Trawick]
374 *) forward port of buffer overflow fixes for htdigest. [Thom May]
376 *) Added AllowEncodedSlashes directive to permit control of whether
377 the server will accept encoded slashes ('%2f') in the URI path.
378 Default condition is off (the historical behaviour). This permits
379 environments in which the path-info needs to contain encoded
380 slashes. PR 543, 2389, 3581, 3589, 5687, 7066, 7865, 14639. [Ken Coar]
382 *) When using Redirect in directory context, append requested query
383 string if there's no one supplied by configuration. PR 10961.
386 *) Unescape the supplied wildcard pattern in mod_autoindex. Otherwise
387 the pattern will not always match as desired. PR 12596.
390 *) mod_autoindex now emits and accepts modern query string parameter
391 delimiters (;). Thus column headers no longer contain unescaped
392 ampersands. PR 10880 [André Malo]
394 *) Enable ap_sock_disable_nagle for Windows. This along with the
395 addition of APR_TCP_NODELAY_INHERITED to apr.hw will cause Nagle
396 to be disabled for Windows. [Allan Edwards]
398 *) Correct a mis-correlation between mpm_common.c and mpm_common.h;
399 This patch reverts us to pre-2.0.46 behavior, using the
400 ap_sock_disable_nagle noop macro, because ap_sock_disable_nagle
401 was never compiled on Win32. [Allan Edwards, William Rowe]
403 *) Fix a build problem with passing unsupported --enable-layout
404 args to apr and apr-util. This broke binbuild.sh as well as
405 user-specified layout parameters. PR 18649 [Justin Erenkrantz,
408 *) If a Date response header was already set in the headers array,
409 this value was ignored in favour of the current time. This meant
410 that Date headers on proxied requests where rewritten when they
411 should not have been. PR: 14376 [Graham Leggett]
413 *) Add code to buildconf that produces an httpd.spec file from
414 httpd.spec.in, using build/get-version.sh from APR.
417 *) Fixed a segfault when multiple ProxyBlock directives were used.
418 PR: 19023 [Sami Tikka <sami.tikka@f-secure.com>]
420 *) SECURITY [CAN-2003-0134] OS2: Fix a Denial of Service vulnerability
421 identified and reported by Robert Howard <rihoward@rawbw.com> that
422 where device names faulted the running OS2 worker process.
423 The fix is actually in APR 0.9.4. [Brian Havard]
425 *) Forward port: Escape special characters (especially control
426 characters) in mod_log_config to make a clear distinction between
427 client-supplied strings (with special characters) and server-side
428 strings. This was already introduced in version 1.3.25.
431 *) mod_deflate: Check also err_headers_out for an already set
432 Content-Encoding: gzip header. This prevents gzip compressed content
433 from a CGI script from being compressed once more. PR 17797.
436 Changes with Apache 2.0.45
438 *) Fix possible segfaults under obscure error conditions within the
439 cgid daemon. [Jeff Trawick, William Rowe]
441 *) SECURITY [CAN-2003-0132]: Close a Denial of Service vulnerability
442 identified by David Endler <DEndler@iDefense.com> on all platforms.
443 An unlimited stream of newlines were acceptable between requests
444 where each <lf> would allocate an 80 byte buffer, leading very
445 quickly to memory exahustion. [Brian Pane]
447 *) Added an rpm build script.
448 [Graham Leggett, Joe Orton <jorton@redhat.com>]
450 *) Simpler, faster code path for request header scanning [Brian Pane]
452 *) SECURITY: Eliminated leaks of several file descriptors to child
453 processes, such as CGI scripts. This fix depends on the APR library
454 release 0.9.2 or later (0.9.3 was distributed with the httpd
455 source tarball for Apache 2.0.45.) PR 17206
456 [Christian Kratzer <ck@cksoft.de>, Bjoern A. Zeeb <bz@zabbadoz.net>]
458 *) Fix path handling of mod_rewrite, especially on non-unix systems.
459 There was some confusion between local paths and URL paths.
460 PR 12902. [André Malo]
462 *) Prevent endless loops of internal redirects in mod_rewrite by
463 aborting after exceeding a limit of internal redirects. The
464 limit defaults to 10 and can be changed using the RewriteOptions
465 directive. PR 17462. [André Malo]
467 *) Win32: Avoid busy wait (consuming all the CPU idle cycles) when
468 all worker threads are busy.
469 [Igor Nazarenko <igor_nazarenko@hotmail.com>]
471 *) Keep the subrequest filter in place when a subrequest is
472 redirected. PR 15423. [Jeff Trawick]
474 *) you can now specify the compression level for mod_deflate.
475 [Ian Holsman, Stephen Pierzchala <stephen@pierzchala.com>,
476 Michael Schroepl <Michael.Schroepl@telekurs.de>]
478 *) mod_deflate: Extend the DeflateFilterNote directive to
479 allow accurate logging of the filter's in- and outstream.
482 *) Allow SSLMutex to select/use the full range of APR locking
483 mechanisms available to it. Also, fix the bug that SSLMutex uses
484 APR_LOCK_DEFAULT no matter what. PR 8122 [Jim Jagielski,
485 martin.t.kutschker@blackbox.net (Martin Kutschker)]
487 *) Restore the ability of htdigest.exe to create files that contain
488 more than one user. PR 12910. [André Malo]
490 *) Improve binary compatibility of the core between debug (aka
491 maintainer-mode) and a non-debug compile.
494 *) mod_usertrack: don't set the cookie in subrequests. This works
495 around the problem that cookies were set twice during fast internal
496 redirects. PR 13211. [André Malo]
498 *) mod_autoindex no longer forgets output format and enabled version
499 sort in linked column headers. [André Malo]
501 *) Use .sv instead of .se as extension for Swedish documents in the
502 default configuration. PR 12877. [André Malo]
504 *) Updated mod_ldap and mod_auth_ldap to support the Novell LDAP SDK SSL
505 and standardized the LDAP SSL support across the various LDAP SDKs.
506 Isolated the SSL functionality to mod_ldap rather than speading it
507 across mod_auth_ldap and mod_ldap. Also added LDAPTrustedCA
508 and LDAPTrustedCAType directives to mod_ldap to allow for a more
509 common method of specifying the SSL certificate.
510 [Dave Ward, Brad Nicholes]
512 *) Fixed mod_ssl's SSLCertificateChain initialization to no longer
513 skip the first cert of the chain by default. This misbehavior
514 was introduced in 2.0.34. PR 14560 [Madhusudan Mathihalli]
516 *) mod_cgi, mod_cgid, mod_ext_filter: Log errors when scripts cannot
517 be started on Unix because of such problems as bad permissions,
518 bad shebang line, etc. [Jeff Trawick]
520 *) Fix 64-bit problem in mod_ssl input logic.
521 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
523 *) Fix potential memory leaks in mod_deflate on malformed data. PR 16046.
526 *) Rewrite ap_xml_parse_input to use bucket brigades. PR 16134.
529 *) Fix segfault which occurred when a section in an included
530 configuration file was not closed. PR 17093. [André Malo]
532 *) Enhance the behavior of mod_isapi's WriteClient() callback to
533 provide better emulation for isapi modules that presume that the
534 first WriteClient() call may send status and headers. An example
535 of WriteClient() abuse is the foxisapi module, which relies on
536 that assumpion and now works. [William Rowe, Milan Kosina]
538 *) Check the return value of ap_run_pre_connection(). So if the
539 pre_connection phase fails (without setting c->aborted)
540 ap_run_process_connection is not executed. [Stas Bekman]
542 *) Fixed a problem with mod_ldap which caused it to fault when caching
543 was disabled. Needed to make sure that the code did not
544 attempt to use the cache if it didn't exist. Also fixed some memory
545 leaks which were due to not releasing LDAP resources on error
546 conditions. [Brad Nicholes]
548 *) Hook mod_proxy's fixup before mod_rewrite's fixup, so that by
549 mod_rewrite proxied URLs will not be escaped accidentally by
550 mod_proxy's fixup. PR 16368 [André Malo]
552 *) While processing filters on internal redirects, remember seen EOS
553 buckets also in the request structure of the redirect issuer(s). This
554 prevents filters (such as mod_deflate) from adding garbage to the
555 response. PR 14451. [André Malo]
557 *) suexec: Be more pedantic when cleaning environment. Clean it
558 immediately after startup. PR 2790, 10449.
559 [Jeff Stewart <jws@purdue.edu>, André Malo]
561 *) Fix apxs to insert LoadModule directives only outside of sections.
562 PR 8712, 9012. [André Malo]
564 *) Fix suexec compile error under SUNOS4, where strerror() doesn't
565 exist. PR 5913, 9977.
566 [Jonathan W Miner <Jonathan.W.Miner@lmco.com>]
568 *) Fix If header parsing when a non-mod_dav lock token is passed to it.
569 PR 16452. [Justin Erenkrantz]
571 *) mod_auth_digest no longer tries to guess AuthDigestDomain, if it's
572 not specified. Now it assumes "/" as already documented. PR 16937.
575 *) Try to log an error if a piped log program fails. Try to

1198 to configure the maximum amount of memory the allocators will
1199 hold on to for reuse. Anything over the MaxMemFree threshold
1200 will be free()d. This directive is useful when uncommon large
1201 peaks occur in memory usage. It should _not_ be used to mask
1202 defective modules' memory use. [Sander Striker]
1204 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
1205 scripts would not result in a truncated response.
1206 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
1208 *) Add a filter_init parameter to the filter registration functions
1209 so that a filter can execute arbitrary code before the handlers
1210 are invoked. This resolves a problem where mod_include requests
1211 would incorrectly return a 304. [Justin Erenkrantz]
1213 *) Fix a long-standing bug in 2.0, CGI scripts were being called
1214 with relative paths instead of absolute paths. Apache 1.3 used

1238 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
1239 extended characters (non US-ASCII) in non-utf8 format. This brings

1241 to the cgi application itself. [William Rowe]
1243 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
1244 modules to bring them up to the current apr/apr-util APIs.
1247 *) Fix segfault in mod_mem_cache most frequently observed when

1276 tmpnam being unsafe. [Ryan Bloom]
1278 *) We must set the MIME-type for .shtml files to text/html if we want them

1286 *) Make the default_handler catch all requests that aren't served by
1287 another handler. This also gets us to return a 404 if a directory
1288 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1289 loaded. [Justin Erenkrantz]
1291 *) Fixed the handling of nested if-statements in shtml files.
1292 PR 9866 [Brian Pane]
1294 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1295 into a directory different from the one that was configured. This
1296 also mirrors the root= feature from 1.3. We cannot use prefix=,
1297 because both APR and APR-util resolve their installation paths at
1298 configuration time. This means that there is no variable prefix
1299 to replace. [Andreas Hasenack <andreas@netbank.com.br>]
1301 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1302 These levels of AIX don't have a thundering herd problem with
1303 accept(). [Jeff Trawick]
1305 *) prefork MPM: Ignore mutex errors during graceful restart. For
1306 certain types of mutexes (particularly SysV semaphores), we
1307 should expect to occasionally fail to obtain or release the
1308 mutex during restart processing. [Jeff Trawick]
1310 *) Fix install-bindist.sh so that it finds any perl instead of just
1311 early perl 5.x versions. This is consistent with a build/install
1312 from source, and it allows the perl scripts installed by a bindist
1313 to work on systems with perl 5.6. [Jeff Trawick]

1690 at init everytime you use the MMapFile directive. PR 8314
1693 *) Trigger an error when a LoadModule directive attempts to
1694 load a module which is built-in. This is a common error when
1695 switching from a DSO build to a static build. [Jeff Trawick]
1697 *) Change instdso.sh to use libtool --install everywhere and then
1698 clean up some stray files and symlinks that libtool leaves around
1699 on some platforms. This gets subversion building properly since
1700 it needed a re-link to be performed by libtool at install time,
1701 and the old instdso.sh logic to simply cp the DSO didn't handle
1702 that requirement. [Sander Striker]
1704 *) Allow VPATH builds to succeed when configured from an empty
1705 directory. [Thom May <thom@planetarytramp.net>]
1707 *) Fix 'control reaches end of non-void function' warning in
1708 server/log.c. [Ben Collins-Sussman <sussman@collab.net>]
1710 *) Perchild MPM is now correctly deemed as experimental and is now
1711 located in server/mpm/experimental. [Justin Erenkrantz]
1713 *) Fix segfault in mod_mem_cache when garabge collecting an expired
1714 cache entry. [Bill Stoddard]
1716 *) Introduced -E startup_logfile_name option to httpd to allow admins
1717 to begin logging errors immediately. This provides Win32 users
1718 an alternative to sending startup errors to the event viewer, and
1719 allows other daemon tool authors an alternative to logging to stderr.

1739 *) Properly substitute sbindir as httpd's location in apachectl. PR 7840.
1740 [Andreas Hasenack <andreas@netbank.com.br>]
1742 *) Allow Win32 shebang scripts to follow the path (or omit the .exe
1743 suffix from the shebang command), and allow ScriptInterpreterSource
1744 Registry or RegistryStrict to override shebang lines, as 1.3 did.
1745 PR 8004 [William Rowe]
1747 *) worker MPM: Fix a situation where a child exited without releasing
1748 the accept mutex. Depending on the OS and mutex mechanism this
1749 could result in a hang. [Jeff Trawick]
1751 *) Update the instructions for how to get started with mod_example.

1755 rel_logfiledir. PR 7841. [Andreas Hasenack <andreas@netbank.com.br>]
1757 *) Win32: Fix problem that caused rapid performance degradation
1758 when number of connecting clients exceeded ThreadsPerChild.
1761 *) Fixed a segfault parsing large SSIs on non-mmap systems.
1764 *) Proxy was bombing out every second keepalive request, caused by a
1765 stray CRLF before the second response's status line. Proxy now
1766 tries to read one more line if it encounters a CRLF where it
1767 expected a status. PR 10010 [Graham Leggett]
1769 *) Deprecated the apr_lock.h API. Please see the following files
1770 for the improved thread and process locking and signaling:
1771 apr_proc_mutex.h, apr_thread_mutex.h, apr_thread_rwlock.h,
1772 apr_thread_cond.h, and apr_global_mutex.h. [Aaron Bannert]
1774 *) Change mod_status to use scoreboard accessor functions so it can
1775 be used in any MPM without having to be recompiled.
1776 [Ryan Morgan <rmorgan@covalent.net>]
1778 *) Fix parsing of some AP_DECLARE_DATA declarations so that the filter

1799 Changes with Apache 2.0.35
1801 *) mod_rewrite: updated to use the new APR global mutex type.
1804 *) Fixes for mod_include errors on boundary conditions in which
1805 "<!--#" occurs at the very end of a bucket
1806 [Paul Reder, Brian Pane]
1808 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
1809 cause the Apache parent process to run in the foreground (similar to
1810 -DNO_DETACH except that it doesn't switch session ids).
1813 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
1814 for those platforms that support it. If using the default
1815 implementation, this is between pthread and sysvsem in priority.
1816 This implies it's the new default for Darwin. [Jim Jagielski]
1818 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
1819 environment variables in the envvars file. [Jeff Trawick]
1821 *) worker MPM: Don't create a listener thread until we have a worker
1822 thread. Otherwise, in situations where we'll have to wait a while
1823 to take over scoreboard slots from a previous generation, we'll be
1824 accepting connections we can't process yet. [Jeff Trawick]
1826 *) Allow worker MPM to build on systems without pthread_kill().
1827 [Pier Fumagalli, Jeff Trawick]
1829 *) Prevent ap_add_output_filters_by_type from being called in
1830 ap_set_content_type if the content-type hasn't changed.
1833 *) Performance: implemented the bucket allocator made possible by the
1834 API change in 2.0.34. [Cliff Woolley]
1836 *) Don't allow initialization to succeed if we can't get a socket
1837 corresponding to one of the Listen statements. [Jeff Trawick]
1839 Changes with Apache 2.0.34
1841 *) Allow all Perchild directives to accept either numerical UID/GID
1842 or logical user/group names. [Scott Lamb <slamb@slamb.org>]
1844 *) Make Perchild compile cleanly and serve pages again. [Ryan Bloom]
1846 *) implement ssl proxy to support ProxyPass / https:// and the
1847 SSLProxy* directives [Doug MacEachern]
1849 *) Update mod_cgid to not do single-byte socket reads for CGI headers
1852 *) Made AB's use of the Host: header rfc2616 compliant
1853 by Taisuke Yamada <tai@iij.ad.jp> [Dirk-Willem van Gulik].
1855 *) The old, legacy (and unused) code in which the scoreboard was totally
1856 and completely contained in a file (SCOREBOARD_FILE) has been
1857 removed. This does not affect scoreboards which are *mapped* to
1858 files using named-shared-memory. [Jim Jagielski]
1860 *) Change bucket brigades API to allow a "bucket allocator" to be
1861 passed in at certain points. This allows us to implement freelists
1862 so that we can stop using malloc/free so frequently.
1863 [Cliff Woolley, Brian Pane]
1865 *) Add support for macro expansion within the variable names in
1866 <!--#echo--> and <!--#set--> directives [Brian Pane]

1870 *) Update the "RedHat" Layout to match Red Hat Linux version 7. PR BZ-7422
1873 *) add compat layer to support RSA SSLC 1.x and 2.x in mod_ssl
1874 [Jon Travis, John Barbee, William Rowe, Ryan Bloom, Doug MacEachern]
1876 *) Add a new parameter to the quick_handler hook to instruct
1877 quick handlers to optionally do a lookup rather than actually
1878 serve content. This is the first of several changes required fix
1879 several problems with how quick handlers work with subrequests.
1882 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]
1884 *) [APR-related] The ordering of the default accept mutex method has
1885 been changed to better match what's done in Apache 1.3. The ordering
1886 is now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
1889 *) Ensure that the build/ directory is created when using VPATH.
1892 *) Add some popular types to the mime magic file. PR 7730.
1893 [Linus Walleij <triad@df.lth.se>, Justin Erenkrantz]
1895 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
1897 *) When a proxied site was being served, Apache was replacing
1898 the original site Server header with it's own, which is not
1899 allowed by RFC2616. Fixed. [Graham Leggett]
1901 *) Fix a mod_cgid problem that left daemon processes stranded
1902 in some server restart scenarios. [Jeff Trawick]
1904 *) Added exp_foo and rel_foo variables to config_vars.mk for
1905 all Apache and Autoconf path variables (like --sysconfdir,
1906 --sbindir, etc). exp_foo is the "expanded" version, which means
1907 that all internal variable references have been interpolated.
1908 rel_foo is the same as $exp_foo, only relative to $prefix if they
1909 share a common path. [Aaron Bannert]
1911 *) Fix some restart/terminate problems in the worker MPM. Don't
1912 drop connections during graceful restart. [Jeff Trawick]
1914 *) Change the header merging behaviour in proxy, as some headers
1915 (like Set-Cookie) cannot be unmerged due to stray commas in
1916 dates. [Graham Leggett]
1918 *) Be more vocal about what AcceptMutex values we allow, to make
1919 us closer to how 1.3 does it. [Jim Jagielski]
1921 *) Get nph- CGI scripts working again. PRs 8902, 8907, 9983
1924 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
1926 *) Add accessor function to set r->content_type. From now on,
1927 ap_rset_content_type() should be used to set r->content_type.
1928 This change is required to properly implement the
1929 AddOutputFilterByType configuration directive.
1930 [Bill Stoddard, Sander Striker, Ryan Bloom]
1932 *) Add new M_FOO symbols for the WebDAV/DeltaV methods specified by
1933 RFC 3253. Improved the method name/number mapping functions.
1936 *) remove sock_enable_linger from connection.c [Ian Holsman]
1938 *) Fix for virtual host processing where the requested hostname
1939 has a '.' at the end (PR 9187) [Ryan Cruse <ryan@estara.com>]
1941 *) mod_dav's APIs for REPORT response handling was changed so that
1942 providers can generate the content directly into the output filter
1943 stack, rather than buffering the response into memory. [Greg Stein]
1945 *) Fix a hang condition with graceful restart and prefork MPM
1946 in the situation where MaxClients is very high but
1947 much fewer servers are actually started at the time of the
1948 restart. [Jeff Trawick]
1950 *) Small performance fixes for mod_include [Brian Pane]
1952 *) Performance improvement for the error logger [Brian Pane]
1954 *) Change configure so that Solaris 8 and above have
1955 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
1956 according to sun people solaris 8+ doesn't have a thundering
1957 herd problem [Ian Holsman]
1959 *) Allow URIs specifying CGI scripts to include '/' at the end
1960 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
1961 which ignore '/' at the end of the names of non-directories).

1967 *) Fix apxs -g handling. Move config_vars.mk from the top build
1968 directory to the build directory. PR 10163 [Jeff Trawick]
1970 *) Fix some mod_include problems which broke evaluation of some
1971 expressions. PR 10108 [Jeff Trawick]
1973 *) Fix the calculation of request time in mod_status. [Stas Bekman]
1975 *) Fix the calculation of thread_num in the worker score structure.
1978 *) Use apr_atomic operations in managing the mod_mem_cache
1979 cache_objects for SMP scalability. (see USE_ATOMICS
1980 preprocessor directive in mod_file_cache)
1983 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
1984 preprocessor directive in mod_file_cache)
1987 *) Implement prototype mod_disk_cache for use with mod_cache.
1990 *) Add a missing manualdir entry in the Debian config.layout.
1991 [Thom May <thom@planetarytramp.net>]
1993 *) Stop installing libtool for APR and tell APR where it should place
1994 its copy of libtool (via our installbuildpath layout variable).
1997 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
1998 when reading from a remote HTTP server in proxy. [Graham Leggett]
2000 *) Modify receive/send loop in proxy_http and proxy_ftp so that
2001 should it be necessary, the remote server socket is closed before
2002 transmitting the last buffer (set by ProxyIOBufferSize) to the
2003 client. This prevents the backend server from being forced to hang
2004 around while the last few bytes are transmitted to a slow client.
2005 Fix the case where no error checking was performed on the final
2006 brigade in the loop. [Graham Leggett]
2008 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
2009 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
2010 hours. [Graham Leggett, Bill Stoddard]
2012 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
2013 for a undefined variable. [Ian Holsman]
2015 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
2016 when we can't get a socket in the specified address family. We may
2017 have gotten back an IPv6 address first and yet our system is not
2018 configured to allow IPv6 sockets. [Jeff Trawick]
2020 *) Be more careful about recursively removing CVS directories. Make
2021 sure that we aren't cd'ing to their home directory first. PR: 9993
2022 [Aaron Bannert, James LewisMoss <dres@lewismoss.net>]
2024 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
2025 [Dirk-Jan Faber <dirk-jan@selwerd.nl>, Aaron Bannert,
2026 Thom May <thom@planetarytramp.net>]
2028 *) Rename the filter ordering priorities. The recent filtering fixes
2029 have showcased problems with their usage. Therefore, we need to
2030 rename them to increase the clarity. (CONTENT->RESOURCE,
2031 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
2033 Changes with Apache 2.0.33
2035 *) Fix a problem in the new --enable-layout functionality where
2036 it wouldn't allow overrides from variables like --prefix,
2037 --bindir, etc. [Thom May <thom@planetarytramp.net>]
2039 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
2040 no longer hangs around waiting for the socket to close before
2041 returning exhaustive data. [Aaron Bannert]
2043 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
2044 [Thom May <thom@planetarytramp.net>]
2046 *) Change mod_ssl to always do a full startup/teardown on restarts.
2047 this allows mod_ssl to be added to a server that is already
2048 running and makes it possible to add/change certs/keys after the
2049 server has been started. [Doug MacEachern]
2051 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
2052 This pipe must be a bidirectional 'console' style relay, which
2053 mod_ssl prints all prompts to the pipe's stdin, and reads the
2054 passphrases from the pipe's stdout. [William Rowe]
2056 *) Fix bug where --sysconfdir and --localstatedir were being
2057 ignored. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
2060 *) Fix --enable-layout to work again. Caution: When specifying
2061 --enable-layout, common arguments like --prefix, --exec-prefix,
2062 etc. will be ignored and the settings from the layout will be
2063 used instead. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
2066 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
2067 regex pattern matching for the determination of which requests
2068 to use the remote proxy for. [Jim Jagielski]
2070 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
2072 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
2073 cruft in piped logs and rewritemap child processes.
2076 *) All instances of apr_lock_t have been removed and converted
2077 to one of the following new lock APIs: apr_thread_mutex.h,
2078 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
2079 use the apr_lock.h API, as the old API will soon be deprecated.
2082 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
2083 [Ralf S. Engelschall, Cliff Woolley]
2085 *) mod-include: make it handle flush'es and fix the 'false-alarm'
2086 [Justin Erenkrantz, Brian Pane, Ian Holsman]
2088 *) ap_get_*_filter_handle() functions to allow 3rd party modules
2089 to lookup filter handles so they can bypass the filter name
2090 lookup when adding filters to a request (via ap_add_*_filter_handle())
2091 [Ryan Morgan <rmorgan@covalent.net>]
2093 *) Fix for multiple file buckets on Win32, where the first file
2094 bucket would cause the immediate closure of the socket on any
2095 non-keepalive requests. [Ryan Morgan <rmorgan@covalent.net>]
2097 *) Correct Win32 failure of mmap of a segment beyond start of the
2098 file; fixes large SSL and similar transfers. [William Rowe]
2101 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
2102 multi-process mode to not "daemonize" while detaching from the
2103 controlling terminal. This is necessary for Apache to work with
2104 process-management tools like AIX's "System Resource Controller"
2105 as well as Dan Bernstein's "daemontools".
2106 [Jos Backus <josb@cncdsl.com>, Aaron Bannert]
2108 *) Convert mod_auth_digest to use the new apr_global_mutex_t
2109 type. [Aaron Bannert]
2111 *) fix bug in mod-include where it wouldn't send a unmatched
2112 part if it was at the end of a bucket [Ian Holsman]
2114 *) worker MPM: Improve logging of errors with the interface between
2115 the listener thread and worker threads. [Jeff Trawick]
2117 *) Some browsers ignore cookies that have been merged into a
2118 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
2119 are now unmerged in the http proxy before being sent to the
2120 client. [Graham Leggett]
2122 *) Fix a problem with proxy where each entry of a duplicated
2123 header such as Set-Cookie would overwrite and obliterate the
2124 previous value of the header, resulting in multiple header
2125 values (like cookies) going missing.
2126 [Graham Leggett, Joshua Slive]
2128 *) Add the server-limit and thread-limit values to the scoreboard
2129 for the sake of third-party applications.
2130 [Adam Sussman <myddryn@vishnu.vidya.com>]
2132 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
2134 *) OS/390: Get make install to properly copy DSO modules.
2137 *) Win32: Fix bug in mod_status with displaying "Restart Time"
2138 and "Server uptime".
2141 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
2143 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
2145 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.

2148 *) Fix incorrect check for script_in in mod_cgi. PR 9669.

2151 *) Fix segfault and display error when SSLMutex file can not be
2152 created. [Adam Sussman <myddryn@vishnu.vidya.com>]
2154 *) Add reference counting to mod_mem_cache cache objects to
2155 better manage removing objects from the cache.
2158 *) Change the verbage on the ScoreBoardFile in our default configs.
2159 Also change the default to be commented out (unspecified) so we
2160 get anonymous shared memory by default. [Aaron Bannert]
2162 *) Implement new ScoreBoardFile directive logic. This affects how
2163 we create the scoreboard's shared memory segment. If the directive
2164 is present, a name-based segment is created. If the directive is
2165 not present, first an anonymous segment is created, and if that
2166 fails, a name-based segment is created from a file of the name
2167 DEFAULT_SCOREBOARD. This gives third-party applications the
2168 ability to access our scoreboard. [Aaron Bannert]
2170 *) Allow mod_deflate to work with non-GET requests and properly send
2171 Content-Lengths. [Sander Striker <striker@apache.org>]
2173 *) Fix ap_directory_merge() to correctly merge configs when there is
2174 no <Directory /> block. [Justin Erenkrantz, William Rowe]
2176 *) Remove spurious debug messsages that are normal under HTTP
2177 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
2179 *) Fix a bug in mod_cgid that would prevent proper shutdown death
2180 of the cgid process. [Aaron Bannert]
2182 *) Add signal handling back in to the worker MPM for the one_process
2183 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
2185 *) Performance: Reuse per-connection transaction pools in the
2186 worker MPM, rather than destroying and recreating them. [Brian Pane]
2188 *) Remove all signals from the worker MPM's child process. Instead,
2189 the parent uses the Pipe of Death for all communication with the
2190 child processes. [Ryan Bloom]
2192 Changes with Apache 2.0.32
2194 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
2195 default if the directive is not specified. This mirrors older
2196 behavior without changes to the httpd.conf. [William Rowe]
2198 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
2199 the service, mpm and logging code, and bugs in apr_file_open_stderr
2200 and apr_file_dup2 functions. Win2K/XP services have no handles
2201 associated for stdin/out/err, which caused unpredictable behavior
2202 in the prior release. [William Rowe, Bill Stoddard]
2204 *) Win32: simplify the Application Event Log messages, since there isn't
2205 likely to be 'more information in the error log' before an error log
2206 has been opened. [William Rowe]
2208 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
2209 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
2211 *) Win32: apache -k shutdown now behaves like apache -k stop.
2214 *) Fix prefork to not kill the parent if a child hits a resource shortage
2215 on accept(). [Greg Ames]
2217 *) Fix seg faults that occur when what should be the httpd request line
2218 starts with \r\n followed by garbage. [Greg Ames]
2220 *) Allow statically linked support binaries with the new
2221 --enable-static-support flag, and enable this behavior in
2222 the binbuild script. Also add a new --enable-static-htdbm
2223 flag. [Aaron Bannert]
2225 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
2226 do only one stat() call when generating the directory listings.
2229 *) Fix resolve_symlink to save the original symlink name if known.
2232 *) Be a bit more sane with regard to CanonicalNames. If the user has
2233 specified they want to use the CanonicalName, but they have not
2234 configured a port with the ServerName, then use the same port that
2235 the original request used. [Ryan Bloom and Ken Coar]
2237 *) In core_input_filter, check for an empty brigade after
2238 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
2239 client says it will post some data but we get FIN before any
2240 data arrives. [Jeff Trawick]
2242 *) Not being able to bind to the socket is a fatal error. We should
2243 print an error to the console, and return a non-zero status code.
2244 With these changes, all of the Unix MPMs do that correctly.
2247 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
2248 through to CGI scripts. PR 9163
2249 [Brian Reid <breid@customlogic.com>,
2250 Zvi Har'El <rl@math.technion.ac.il>]
2252 *) binbuild.sh: Make sure that we use the expat from our source
2253 tree so that there aren't any surprises on the target machine.
2256 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2257 enough to keep up with new requests. Start using
2258 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2259 when we can't talk to the daemon. [Jeff Trawick]
2261 *) apxs: LTFLAGS envvar can override default libtool options. Try
2262 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2263 the covers. [Jeff Trawick]
2265 *) The Location: response header field, used for external
2266 redirect, *must* be an absoluteURI. The Redirect directive
2267 tested for that, but RedirectMatch didn't -- it would allow
2268 almost anything through. Now it will try to turn an abs_path
2269 into an absoluteURI, but it will correctly varf like Redirect
2270 if the final redirection target isn't an absoluteURI. [Ken Coar]
2272 Changes with Apache 2.0.31
2274 *) Create the scoreboard (in the parent) in a global pool context,
2275 so it survives graceful restarts. This fixes a SEGV during
2276 graceful restarts. [Aaron Bannert]
2278 *) Add a timeout option to the proxy code 'ProxyTimeout'
2281 *) FTP directory listings are now always retrieved in ASCII mode.
2282 The FTP proxy properly escapes URI's and HTML in the generated
2283 listing, and escapes the path components when talking to the FTP
2284 server. It is now possible to browse the root directory by using
2285 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2286 Also, the last path component may contain wildcard characters
2287 '*' and '?', and if they do, a directory listing is created instead
2288 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2291 *) Added single-listener unserialized accept support to the
2292 worker MPM [Brian Pane]
2294 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2295 the incoming host header through to the proxied server
2296 [Geoff <g.russell@ieee.org>]
2298 *) New Directive Option for ProxyPass. It now can block a location
2299 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
2301 *) Don't let the default handler try to serve a raw directory. At
2302 best you get gibberish. Much worse things can happen depending
2303 on the OS. [Jeff Trawick]
2305 *) Change the pre_config hook to return a value. Modules can now emit
2306 an error message and then cause the server to quit gracefully during
2307 startup. This required a bump to the MMN. [Aaron Bannert]
2309 *) Fix some unix socket descriptor leaks in the handler side of
2310 mod_cgid (the part that runs in the server process). Whack a
2311 silly "close(-1)" in the handler too. [Jeff Trawick]
2313 *) Change the pre_mpm hook to return a value, so that scoreboard
2314 init errors percolate up to code that knows how to exit
2315 cleanly. This required a bump to the MMN. [Jeff Trawick]
2317 *) Add the socket back to the conn_rec and remove the create_connection
2318 hook. The create_connection hook had a design flaw that did not
2319 allow creating connections based on vhost info. [Bill Stoddard]
2321 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2322 Resolves the common case of using negotation to resolve the request
2323 /script/foo for /script.cgi/foo. [William Rowe]
2325 *) Added new functions ap_add_(input|output)_filter_handle to
2326 allow modules to bypass the usual filter name lookup when
2327 adding hard-coded filters to a request [Brian Pane]
2329 *) caching should now work on subrequests (still very experimental)
2332 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2334 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2337 *) Refactor ap_rgetline so that it does not use an internal brigade.
2338 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2340 *) Remove mod_auth_db. [Justin Erenkrantz]
2342 *) Do not install unnecessary pcre headers like config.h and internal.h.
2343 [Joe Orton <joe@manyfish.co.uk>]
2345 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
2346 (as it does for a normal request). quick_handled sub-requests now work
2347 in mod-include [Ian Holsman]
2349 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
2350 'CONTENT' one, as it needs to run AFTER all content headers
2352 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
2355 *) Split out blocking from the mode in the input filters.
2358 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
2360 *) Cause Win32 to capture all child-worker process errors in
2361 Apache to the main server error log, until the child can
2362 open its own error logs. [William Rowe]
2364 *) HPUX 11.*: Do not kill the child process when accept()
2365 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
2366 by [madhusudan_mathihalli@hp.com])
2369 *) Fix a problem in the parsing of the <Proxy foo> directive.
2372 *) rewrite of mod_ssl input filter for better performance and less
2373 memory usage [Doug MacEachern]
2375 *) allow quick_handler to be run on subrequests. [Ian Holsman]
2377 *) mod_dav now asks its provider to place content directly into the
2378 filter stack when handling a GET request. The mod_dav/provider
2379 API has changed, so providers need to be updated. [Greg Stein]
2381 *) Clear the output socket descriptor in unixd_accept() to make sure
2382 we don't supply a bogus socket to the caller if the accept fails.
2383 This caused problems with the worker MPM, which tried to process
2384 the returned socket if it was non-NULL. [Brian Pane]
2386 *) Move a check for an empty brigade to the start of core input filter
2387 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
2389 *) Add FileETag directive to allow configurable control of what
2390 data are used to form ETag values for file-based URIs. MMN
2391 bumped to 20020111 because of fields added to the end of
2392 the core_dir_config structure. [Ken Coar]
2394 *) Fix a segfault in mod_rewrite's logging code caused by passing the
2395 wrong config to ap_get_remote_host(). [Jeff Trawick]
2397 *) Allow mod_cgid to work from a binary distribution install by
2398 using 755 for the permissions on the log directory instead of
2401 *) Fixed a segfault that happened during graceful shutdown (or when
2402 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
2404 *) Split all Win32 modules [excluding the core components mod_core,
2405 mod_so, mod_win32 and the winnt mpm] into individual loadable
2406 modules, so the administrator may individually disable the former
2407 compiled-in modules by simply commenting out their LoadModule
2408 directives. [William Rowe]
2410 *) Saved Win32 module authors and porters many future headaches, by
2411 duplicating the appropriate .h files such as os.h into the include
2412 directory, including in the build tree. [William Rowe]
2414 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
2415 Use SSL functions/macros instead of directly dereferencing SSL
2416 structures wherever possible.
2417 Add type-casts for the cases where functions return a generic pointer.
2418 Add $SSL/include to configure search path.
2419 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
2421 *) Moved several pointers out of the shared Scoreboard so it is
2422 more portable, and will present the vhost name across server
2423 generation restarts. [William Rowe]
2425 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
2428 Changes with Apache 2.0.30
2430 *) Fix the main bug for FreeBSD and threaded MPM's. There are
2431 still issues (see STATUS) but at least the server will now
2432 run without crashing the machine.
2433 [David Reid, Aaron Bannert, Justin Erenkrantz]
2435 *) Fix a typo in mod_deflate's m4 config section.
2436 [albert chin (china@thewrittenword.com)]
2438 *) Fix a couple of mod_proxy problems forwarding HTTP connections
2439 and handling CONNECT:
2440 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
2441 (2) Proxy failed to connect when the first IP address returned by
2442 the resolver was unreachable but a secondary IP address was.
2445 *) Fix the module identifer as shown in the docs for various core
2446 modules (e.g., the identifer for mod_log_config was previously
2447 listed as config_log_module). PR #9338
2448 [James Watson <ap2bug@sowega.org>]
2450 *) Fix LimitRequestBody directive by placing it in the HTTP
2451 filter. [Justin Erenkrantz]
2453 *) Fix mod_proxy seg fault when the proxied server returns
2454 an HTTP/0.9 response or a bogus status line.
2457 *) Prevent mod_proxy from truncating one character off the
2458 end of the status line returned from the proxied server.
2459 [Adam Sussman, Bill Stoddard]
2461 *) Eliminate loop in ap_proxy_string_read().
2462 [Adam Sussman, Bill Stoddard]
2464 *) Provide $0..$9 results from mod_include regex parsing.
2467 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
2469 *) Introduced the ForceLanguagePriority directive, to prevent
2470 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
2471 when using Multiviews. [William Rowe]
2473 *) Fix a problem which prevented mod_cgid and suexec from working
2474 together reliably [Greg Ames]
2476 *) Remove the call to exit() from within mod_auth_digest's post_config
2477 phase. [Aaron Bannert]
2479 *) Fix a problem in mod_auth_digest that could potentially cause
2480 problems with initialized static data on a system that uses DSOs.
2483 *) Fix a segfault in the worker MPM that could happen during
2484 child process exits. [Brian Pane, Aaron Bannert]
2486 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
2488 *) Fix matching of vhosts by ip address so we find IPv4
2489 vhost address when target address is v4-mapped form of
2490 that address. [Jeff Trawick]
2492 *) More performance tweaks to the BNDM string-search algorithm
2493 used to find "<!--#" tokens in mod_include [Brian Pane]
2495 *) Miscellaneous small performance fixes: optimized away various
2496 string copy operations and removed large temp buffers from
2497 the stack [Brian Pane]
2499 *) Fixed startup segfault that occurred when a VirtualHost
2500 directive had a port but no address [Brian Pane]
2502 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
2504 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
2505 if oslevel < WINNT. This should fix several problems reported
2506 Against 2.0.28 on Windows 98 [Bill Stoddard]
2508 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
2509 to fail. [Bill Stoddard]
2511 *) Change core code to allow an MPM to set hard thread/server
2512 limits at startup. prefork, worker, and perchild MPMs now have
2513 directives to set these limits. [Jeff Trawick]
2515 *) Win32: The async AcceptEx() event should be autoreset upon
2516 successful completion of a wait (WaitForSingleObject). This
2517 eliminates a number of spurious
2518 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
2521 *) Move any load library path environment variables out of
2522 apachectl and into a separate environment variable file which
2523 can be more easily tailored by the admin. The environment
2524 variable file as built by Apache may have additional system-
2525 specific settings. For example, on OS/390 we tailor the heap
2526 settings to allow lots of threads. [Jeff Trawick]
2528 *) Use the new APR pool code to reduce pool-related lock
2529 contention in the worker MPM. [Sander Striker]
2531 *) The POD no longer assumes the child is listening on 127.0.0.1
2532 and now pulls the first hostname in the list of listeners to
2533 perform the dummy connect on. This fixes a bug when the user
2534 had configured the Listen directive for an IP other than
2535 127.0.0.1. This would result in undead children and error
2536 messages such as "Connection refused: connect to listener".
2539 *) The worker MPM now respects the LockFile setting, needed to
2540 avoid locking problems with NFS. [Jeff Trawick]
2542 *) Fix segfault when worker MPM receives SIGHUP.
2543 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
2545 *) Fix bug that could potentially prevent the perchild MPM from
2546 working with more than one vhost/uid. [Aaron Bannert]
2548 *) Change make install and apxs -i processing of DSO modules to
2549 perform special handling on platforms where libtool doesn't install
2550 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
2551 which prevented standard LoadModule statements from working.
2554 *) Whenever mod_so is enabled (not just when there are DSOs for
2555 our modules), do whatever special magic is required for compiling/
2556 loading third-party modules. This allows third-party DSOs to
2557 be used on an AIX build when there were no built-in modules
2558 built as DSOs. (This should help on OS/390 and BeOS as well.)
2561 *) Allow apxs to be used to build DSOs on AIX without requiring the
2562 user to hard-code the list of import files. (This should help
2563 on OS/390 and BeOS as well.) [Jeff Trawick]
2565 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
2566 PR 8563, 8919 [William Rowe]
2568 *) Get binary builds working when libapr and libaprutil are built
2571 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
2572 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
2573 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
2575 *) Fix the handling of SSI directives in which the ">" of the
2576 terminating "-->" is the last byte in a file [Brian Pane]
2578 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
2579 message that we had back in apache-1.3 and still have scattered
2580 throughout our docs. [Aaron Bannert]
2582 *) Prevent the Win32 port from continuing after encountering an
2583 error in the command line args to apache. [William Rowe]
2585 *) On a error in the proxy, make it write a line to the error log
2588 *) Various mod_ssl performance improvements [Doug MacEachern]
2590 Changes with Apache 2.0.29
2592 *) Add buffering in core_output_filter to ensure that long
2593 lists of small buckets don't cause small packet writes.
2594 [Brian Pane, Ryan Bloom]
2596 *) Fix the installation target to make sure that the manual is
2597 installed in the correct location.
2598 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
2599 Gomez Henri <hgomez@slib.fr>]
2601 *) Fix the cmd command for mod_include. When we are processing
2602 a cmd command, we do not want to use the r->filename to set
2603 the command name. The command comes from the SSI tag. To do this,
2604 I added a variable to the function that builds the command line
2605 in mod_cgi. This allows the include_cmd function to specify
2606 the command line itself. [Ryan Bloom]
2608 *) Change open_logs hook to return a value, allowing you
2609 to flag a error while opening logs
2610 [Ian Holsman, Doug MacEachern]
2612 *) Change post_config hook to return a value, allowing you
2613 to flag a error post config
2614 [Ian Holsman, Jeff Trawick]
2616 *) Allow SUEXEC_BIN (the path to the suexec binary that is
2617 hard-coded into the server) to be specified to the configure
2618 script by the --with-suexec-bin parameter. [Aaron Bannert]
2620 *) Fix segv in worker MPM following accept on pipe-of-death
2623 *) Add mod_deflate to experimental.
2624 [Ian Holsman, Justin Erenkrantz]
2626 *) Bail out at configure time if an invalid MPM was specified.
2627 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2629 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
2630 configured [John Sterling <sterling@covalent.net>]
2632 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
2634 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
2636 *) Optimization for the BNDM string-search function in
2637 mod_include. [Brian Pane]
2639 *) Fixed the behavior of the XBitHack directive.
2640 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
2642 *) The threaded MPM for Unix has been removed. Use the worker
2643 MPM instead. [various]
2645 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
2646 in logging the error from a failed DNS lookup. [Jeff Trawick]
2648 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
2651 *) Get mod_cgid killed when a MPM exits due to a fatal error.
2654 *) Fix a file descriptor leak in mod_include. When we include a
2655 file, we use a sub-request, but we didn't destroy the sub-request
2656 immediately, instead we waited until the original request was
2657 done. This patch closes the sub-request as soon as the data is
2658 done being generated. [Brian Pane <bpane@pacbell.net>]
2660 *) Allow modules that add sockets to the ap_listeners list to
2661 define the function that should be used to accept on that
2662 socket. Each MPM can define their own function to use for
2663 the accept function with the MPM_ACCEPT_FUNC macro. This
2664 also abstracts out all of the Unix accept error handling
2665 logic, which has become out of synch across Unix MPMs.
2668 *) Fix a bug which would cause the response headers to be omitted
2669 when sending a negotiated ErrorDocument because the required
2670 filters were attached to the wrong request_rec.
2671 [John Sterling <sterling@covalent.net>]
2673 *) Remove commas from the end of the macros that define
2674 directives that are used by MPMs. Prior to this patch,
2675 you would use these macros without commas, which was unlike
2676 the macros for any other directives. Now, the caller provides
2677 the comma rather than the macro providing it. This makes
2678 the macros look more like the rest of the directives.
2679 [Ryan Bloom and Cliff Woolley]
2681 *) Add 'redirect-carefully' environment option to disable sending
2682 redirects under special circumstances. This is helpful for
2683 Microsoft's WebFolders when accessing a directory resource via
2684 DAV methods. [Justin Erenkrantz]
2686 *) Begin to abstract out the underlying transport layer.
2687 The first step is to remove the socket from the conn_rec,
2688 the server now lives in a context that is passed to the
2689 core's input and output filters. This forces us to be very
2690 careful when adding calls that use the socket directly,
2691 because the socket isn't available in most locations.
2694 *) Really reset the MaxClients value in worker and threaded
2695 when the configured value is not a multiple of the number
2696 of threads per child. We said we did previously but we
2697 forgot to. [Jeff Trawick]
2699 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
2701 *) If shared modules are requested and mod_so is not available,
2702 produce a fatal config-time error. [Justin Erenkrantz]
2704 *) Improve http2env's performance by cutting the work it has to
2705 do. [Brian Pane <bpane@pacbell.net>]
2707 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
2708 [Brian Pane <bpane@pacbell.net>]
2710 Changes with Apache 2.0.28
2712 *) Fix infinite loop in mod_cgid.c.
2713 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
2715 *) When no port is given in a "ServerName host" directive, the
2716 server_rec->port is now set to zero, not 80. That allows for
2717 run-time deduction of the correct server port (depending on
2718 SSL/plain, and depending also on the current setting of
2719 UseCanonicalName). This change makes redirections
2720 work, even with https:// connections. As in Apache-1.3, the
2721 connection's actual port number is never used, only the ServerName
2722 setting or the client's Host: setting. Documentation updated
2723 to reflect the change. [Martin Kraemer]
2725 *) Add a '%{note-name}e' argument to mod-headers, which works in
2726 the same way as mod_log_confg. [Ian Holsman]
2728 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
2729 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
2730 MPMs. [Cliff Woolley]
2732 *) Introduce htdbm, a user management utility for db/dbm authorization
2733 databases. [Mladen Turk <mturk@mappingsoft.com>]
2735 *) Optimize usage of strlen and strcat in ap_directory_walk.
2736 [Brian Pane <bpane@pacbell.net>]
2738 Changes with Apache 2.0.27
2740 *) Introduce an Apache mod_ssl initial configuration template
2741 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
2743 *) Fixed a memory leak in the getline parsing code that could
2744 be triggered by arbitrarily large header lines. Requests
2745 from the core input filter for single lines are now limited
2746 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
2748 *) Fix a truncation bug in how we print the port on the Via: header.
2749 The routine that prints the Via: header now takes a length for
2750 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
2752 *) Some syntax errors in mod_mime_magic's magic file can result
2753 in a 500 error, which previously was unlogged. Now we log the
2754 error. [Jeff Trawick]
2756 *) Add the support/checkgid helper app, which checks the run-time
2757 validity of group identifiers usable in the Group directive.
2760 *) Various --enable-so options have been fixed: --enable-so is
2761 treated as "static"; explicit --enable-so=shared issues an error;
2762 and explicit --enable-so fails with error on systems without
2763 APR_HAS_DSO. [Aaron Bannert]
2765 *) Fix a segfault in the core input filter when the client socket
2766 gets disconnected unexpectedly. [Cliff Woolley]
2768 *) Fix the reporting for child processes that die. This removes
2769 all of the non-portable W* macros from Apache.
2770 [Jeff Trawick and Ryan Bloom]
2772 *) Win32: Track and display "Parent Server Generation:" in
2773 mod_status output. The generation will be bumped at
2774 server graceful restart, when the child process exits
2775 by hitting MaxRequestsPerChild or if the child
2776 process exits abnormally. [Bill Stoddard]
2778 *) Win32: Fix problem where MaxRequestsPerChild directive was
2779 not being picked up in favor of the default. Enable
2780 the parent to start up a new child process immediately upon
2781 the old child starting shutdown.
2784 *) Fix some bungling of the remote port in rfc1413.c so that
2785 IdentityCheck retrieves the proper user id instead of failing
2786 and thus always returning "nobody."
2787 [Dick Streefland <Dick.Streefland@xs4all.nl>]
2789 *) Introduced thread saftey for mod_rewrite's internal cache.
2790 [Brian Pane <bpane@pacbell.net>]
2792 *) Simplified mod_env's directives to behave as most directives are
2793 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
2794 directive following that UnsetEnv within the same container.
2795 Also provides a runtime startup warning if a PassEnv configured
2796 environment value is undefined. [William Rowe]
2798 *) The worker MPM is now completely ported to APR's new lock API. It
2799 uses native APR types for thread mutexes, cross-process mutexes,
2800 and condition variables. [Aaron Bannert]
2802 *) Sync up documentation to remove all references to the now deprecated
2803 Port directive. [Justin Erenkrantz]
2805 *) Moved all ldap modules from the core to httpd-ldap sub-project
2808 *) Exit when we can't listen on any of the configured ports. This
2809 is the same behavior as 1.3, and it avoids having the MPMs to
2810 deal with bogus ap_listen_rec structures. [Jeff Trawick]
2812 *) Cleanup the proxy code that creates a request to the origin
2813 server. This change adds an optional hook, which allows modules
2814 to gain control while the request is created if the proxy module
2815 is loaded. The purpose of this hook is to allow modules to add
2816 input and/or output filters to the request to the origin. While
2817 I was at it, I made the core use this hook, so that proxy request
2818 creation uses some of the code from the core. This can still be
2819 greatly improved, but this is a good start. [Ryan Bloom]
2821 Changes with Apache 2.0.26
2823 *) Port the MaxClients changes from the worker MPM to the threaded
2826 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
2827 with the new input filtering system. [Justin Erenkrantz]
2829 *) Introduce the MultiviewsMatch directive, to allow the operator
2830 to be flexible in recognizing Handlers and Filters filename
2831 extensions as part of the Multiviews matching logic, strict with
2832 MultiviewsMatch NegotiatedOnly to accept only filename extentions
2833 that designate negotiated parameters, (content type, charset, etc.)
2834 or MultiviewsAll for the 1.3 behavior of matching any files, even
2835 if they have unregistered extensions. [William Rowe]
2837 *) Fixed the configure script to add a LoadModule directive to
2838 the default httpd.conf for any module that was compiled
2839 as a DSO. [Aaron Bannert <aaron@clove.org>]
2841 *) rewrite mod_ssl input filtering to work with the new input filtering
2842 system. [Justin Erenkrantz]
2844 *) prefork: Don't segfault when we are able to listen on some but
2845 not all of the configured ports. [Jeff Trawick]
2847 *) Build mod_so even if no core modules are built shared.
2848 [Aaron Bannert <aaron@clove.org>]
2850 *) Introduce ap_directory_walk rewrite (with further optimizations
2851 required) to adapt to the ap_process_request_internal() changes.
2852 Optimized so subrequests and redirects now reuse previous section
2853 merges, until we mismatch with the original directory_walk, and
2854 precomputed r->finfo results will cause directory_walk to skip
2855 the most expensive phases of the function. [William Rowe]
2857 *) Allow ApacheMonitor to connect to and control Apache on other
2858 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
2860 *) Remove the Port directive. In it's place, the Listen directive
2861 is now a required directive, which tells Apache what port to
2862 listen on. The ServerName directive has also been extended
2863 to accept an optional port. If the port is specified to the
2864 ServerName, the server will report that port whenever it
2865 reports the port that it is listening on. This change was
2866 made to ease configuration errors that stem from having a Port
2867 directive, and a Listen directive. In that situation, the server
2868 would only listen to the port specified by the Listen command,
2869 which caused a lot of confusion to users. [Ryan Bloom]
2871 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
2872 build, as loadable modules. [William Rowe]
2874 *) Fix --enable-mods-shared processing. If most is specified,
2875 then all modules that can be compiled as shared modules are.
2876 [Aaron Bannert <aaron@clove.org>]
2878 *) Update the mime.types file to map video/vnd.mpegurl to mxu
2879 and add commonly used audio/x-mpegurl for m3u extensions.
2880 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
2882 *) Eliminate the depreciated r->content_language, in favor of the array
2883 r->content_languages introduced many years ago. Module authors must
2884 substantially overhaul their modules, so this needs to be upgraded
2885 if the module still relied on backwards-brokeness. [William Rowe]
2887 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
2890 *) Rewrite the input filtering mechanisms to consolidate and reorganize
2891 code. In short, core_input_filter does something now and
2892 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
2894 *) Update the Win32 build to re-absorb mod_proxy and family.
2897 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
2898 current SDK.) [William Rowe]
2900 *) Some style changes to the code that does ProxyErrorOverride. Fixed
2901 config merge behaviour. [Graham Leggett]
2903 *) Allow support programs to be compiled against a static version
2904 of libapr. This allows the smaller support programs to be
2905 relocated. [Aaron Bannert <aaron@clove.org>]
2907 *) Update the mime.types file to the registered media types as
2908 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
2910 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
2911 number of clients that can connect at the same time, instead of
2912 specifying the maximum number of child processes.
2913 [Aaron Bannert <aaron@clove.org>]
2915 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
2916 be consistent with 1.3. [Justin Erenkrantz]
2918 *) Cache apr_explode_localtime() value for 15 seconds.
2919 [Brian Pane <bpane@pacbell.net>]
2921 *) Fix mod_include to not return ETag or Last-Modified headers.
2922 [Ian Holsman <ianh@cnet.com>]
2924 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
2926 *) Eliminate the wasteful run-time conversion of method names from strings
2927 to numbers in places where the methods are known at compile time.
2928 [Brian Pane <bpane@pacbell.net>]
2930 *) Turn the worker MPM's queue into a LIFO. This may
2931 improve cache-hit performance under some conditions.
2932 [Aaron Bannert <aaron@clove.org>]
2934 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
2935 support it. [Justin Erenkrantz]
2937 *) Cleanup the worker MPM. We no longer re-use transaction
2938 pools. This incurs less overhead than shuffling the pools
2939 around so that they can be re-used. Remove one of the
2940 queue's condition variables. We just redefined the API to
2941 state that you can't try to add more stuff than you allocated
2942 segments for. [Aaron Bannert <aaron@clove.org>]
2944 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
2946 *) Fixed persistent connections when a request contains a body.
2949 *) mod_dav uses a new API to speak to the backend provider for dead
2950 property management. [Greg Stein]
2952 *) Remove the Win32 script-processing exception from mod_cgi, and
2953 roll build_command_line/build_argv_list into a unified, overrideable
2954 ap_cgi_build_command optional function. [William Rowe]
2956 *) Rewrite find_start_sequence to use a better search algorithm
2957 to find the start tag. [Justin Erenkrantz]
2959 *) Fix a seg fault in mod_include. When we are generating an
2960 internal redirect, we must set r->uri to "", not a bogus
2961 string, and not NULL. [Ryan Bloom]
2963 *) Optimized location_walk, so subrequests, redirects and second passes
2964 now reuse previous section merges on a <Location > by <Location >
2965 basis, until we mismatch with the original location_walk.
2968 *) Back out the 1.45 change to util_script.c. This change made
2969 us set the environment variable REQUEST_URI to the redirected
2970 URI, instead of the originally requested URI.
2971 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2973 *) Make mod_include do lazy evaluation of potentially expensive to
2974 compute variables. [Brian Pane <bpane@pacbell.net>]
2976 *) Fix logging of bytes sent for HEAD requests. %b and %B should
2977 log either - or 0, before this patch, they were both logging
2978 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2980 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
2981 than per character. [Brian Pane <bpane@pacbell.net>]
2983 *) Normalize the primary request, redirects and sub-requests to
2984 run the same ap_process_request_internal for consistency in
2985 robustness, behavior and security. [William Rowe]
2987 *) Fix a segfault with mod_include when r->path_info is not set
2988 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
2990 *) Add -X functionality back. This indicates to all MPMs and any other
2991 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
2993 *) Some initial support for the cygwin platform [prefork only].
2994 This is not to be confused with support for the WinNT/Win32
2995 platform, which is the recommended configuration for native
2996 Win32 users. The cygwin platform support is recommended for
2997 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
2999 *) Changed syntax of Set{Input|Output}Filter. The list of filters
3000 must be semicolon delimited (if more than one filter is given.)
3001 The Set{Input|Output}Filter directive now overrides a parent
3002 container's directive (e.g. SetInputFilter in <Directory /web/foo>
3003 will override any SetInputFilter directive in <Directory /web>.)
3004 This new syntax is more consistent with Add{Input|Output}Filter
3005 directives defined in mod_mime. Also cures a bug in prior releases
3006 where the Set{Input|Output}Filter directive would corrupt the
3007 global configuration if the multiple directives were nested.
3010 *) Cured what's ailed mime for quite some time. If an AddSomething
3011 was given in the configuration (Language, Charset, Handler or
3012 Encoding) Apache would set the content type as given by AddType,
3013 but refused to check the mime.types file if AddType wasn't given
3014 for that specific extension. Setting the AddHandler for .html
3015 without setting the AddType text/html html would cause Apache to
3016 use the default content type. [William Rowe]
3018 *) Added some bulletproofing to memory allocation in the LDAP cache
3019 code. [Graham Leggett]
3021 Changes with Apache 2.0.25
3023 *) Move the installed /manual directory out of the /htdocs/ tree, so
3024 that it can be kept more independently from the remaining document
3025 root. The "Alias /manual ..." already allowed for easy projection
3026 into existing private document trees. [Martin Kraemer]
3028 *) Add specified user attributes to the environment when using
3029 mod_auth_ldap. This allows you to use mod_include to embed specified
3030 user attributes in a page like so:
3031 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
3034 *) Fix a performance problem with the worker MPM. We now create
3035 transaction pools once, and re-use them for each connection.
3036 [Aaron Bannert <aaron@clove.org>]
3038 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
3039 of a 'handler' or 'filter', so that any filename extension that does
3040 not contribute to the negotiated metadata can't be served without
3041 an explicit request. E.g., if the .Z extension is associated with
3042 an unzip filter, the user request somefile.Z.html, mod_negotiation
3043 won't serve it. It can serve somefile.Z.html when somefile.Z is
3044 requested, since the .Z extension is explictly requested, if the
3045 .html extension is associated with ContentType text/html.
3048 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
3049 and corresponding AddOutputFilter syntax, to insert one or more
3050 filters by mod_mime filename extension processing.
3053 *) Fix a growing connection pool in core_output_filter() for
3054 keepalive requests. [Jeff Trawick]
3056 *) Moved split_and_pass_pretag_buckets back to being a
3057 macro at Ryans's request. Removed the return from it
3058 by setting and returning a return code instead. Updated
3059 the code to check the return code from the macro and
3060 do the right thing. [Paul J. Reder]
3062 *) Fix a segfault when a numeric value was received for Host:.
3065 *) Add a function ap_remove_input_filter. This is to match
3066 up with ap_remove_output_filter. [Ryan Bloom]
3068 *) Clean up location_walk, so that this step performs a minimum
3069 amount of redundant effort (it must be run twice, but it will no
3070 longer reparse all <Location > blocks when the request uri
3071 hadn't changed.) [William Rowe]
3073 *) Eliminate proxy: (and all other 'special') processing from the
3074 ap_directory_walk() phase. Modules that want to use special
3075 walk logic should refer to the mod_proxy map_to_location example,
3076 with it's proxy_walk and proxysection implementation. This makes
3077 either directory_walk flavor much more legible, since that phase
3078 only runs against real <Directory > blocks.
3081 *) SECURITY: Fix a security problem in mod_include which would allow
3082 an SSI document to be passed to the client unparsed.
3083 [Cliff Woolley, Brian Pane]
3085 *) Introduce the map_to_storage hook, which allows modules to bypass
3086 the directory_walk and file_walk for non-file requests. TRACE
3087 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
3088 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
3091 *) Add the ability for mod_include to add the INCLUDES filter
3092 if the file is configured for the server-parsed handler.
3093 This makes the configuration for .shtml files much easier
3094 to understand, and allows mod_include to honor Apache 1.3
3095 config files. Based on Doug MacEachern's patch to PHP
3096 to do the same thing. [Ryan Bloom]
3098 *) force OpenSSL to ignore process local-caching and to always
3099 get/set/delete sessions using mod_ssl's callbacks
3100 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
3101 Geoff Thorpe <geoff@geoffthorpe.net>]
3103 *) Make the worker MPM shutdown and restart cleanly. This also
3104 cleans up some race conditions, and gets the worker using
3105 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
3107 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
3109 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
3111 *) Fix for mod_include. Ryan's patch to check error
3112 codes put a return in the wrong place. Also, the
3113 include handler return code wasn't being checked.
3114 I don't like macros with returns, so I converted
3115 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
3116 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3118 *) fix segv in mod_mime if no AddTypes are configured
3119 [John Sterling <sterling@covalent.net>]
3121 *) Enable ssl client authentication at SSL_accept time
3122 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
3124 *) Fix a segfault in mod_include when the original request has no
3125 associated filename (e.g., we're filtering the error document for
3126 a bad URI). [Jeff Trawick]
3128 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
3130 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
3131 of httpd is started and shuts down due to socket conflict. Moving the
3132 call to ap_log_pid solves the problem.
3134 *) Changed the late-1.3 log_config substitution %c to %X, to log the
3135 status of the closed connection, as it conflicts with the far more
3136 common, historical ssl logging directive %...{var}c. [William Rowe]
3138 *) Added the common error/ tree to the build/install targets
3139 (similar to the common icons/ tree) for the multi-language error
3140 messages that Lars committed earlier. [William Rowe]
3142 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
3144 *) Added a default commented-out mod_ldap and mod_auth_ldap
3145 configuration to httpd-std.conf and httpd-win.conf
3148 *) Added documentation for mod_ldap and mod_auth_ldap.
3151 *) Enabled negative caching on attribute comparisons in the LDAP cache.
3152 Fixed a problem where the default cache TTL was set in milliseconds
3153 not microseconds causing the cache to time out almost immediately.
3156 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
3157 module code to follow APR. [Graham Leggett]
3159 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
3160 cleaned up when the connection pool pool is cleaned up.
3163 *) Fix a minor issue with Jeff Trawick's mod_include
3164 patch. Without this patch, the code will just allocate
3165 more bytes in get_combined_directive than are needed.
3168 *) Added the LDAP authentication module mod_auth_ldap.
3169 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
3171 *) Added the LDAP cache and connection pooling module mod_ldap.
3172 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
3174 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
3175 by allowing a module to disable itself if its prerequisites are not
3176 met. [Justin Erenkrantz]
3178 Changes with Apache 2.0.24
3180 *) Fix a couple of issues in mod_include when the tag appeared at
3181 offsets near 8192 in the file being parsed. [Jeff Trawick]
3183 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
3184 reached. [Jeff Trawick]
3186 *) Numerous improvements to the Win32 build system. Introduced command line
3187 builds without requiring .mak files for MSVC 6.0 and later versions.
3188 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
3191 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
3192 reporting of uninstalled services and other error conditions, and changed the
3193 default service name to Apache2. [William Rowe]
3195 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
3196 compatibility with existing Apache 1.3 Win32 Apache management utilites.
3197 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
3199 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
3200 [William Rowe, Greg Ames]
3202 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
3203 and RemoveCharset directives. [William Rowe]
3205 *) The Unix MPMs other than perchild now allow child server
3206 processes to use the accept mutex when starting as root and
3207 using SysV sems for the accept mutex. Previously, this
3208 combination would lead to fatal errors in the child server
3209 processes. perchild can't use SysV sems because of security
3210 issues. [Jeff Trawick, Greg Ames]
3212 *) Added Win32 revision stamp resources to all http binaries
3213 (including modules/ and support/ tools.) PR7322 [William Rowe]
3215 *) Fix ap_rvprintf to support more than 4K of data at one time.
3216 [Cody Sherr <csherr@covalent.net>]
3218 *) We have always used the obsolete/deprecated Netscape syntax
3219 for our tracking cookies; now the CookieStyle directive
3220 allows the Webmaster to choose the Netscape, RFC2109, or
3221 RFC2965 format. The new CookieDomain directive allows the
3222 setting of the cookie's Domain= attribute, too. PR #s 5006,
3223 5023, 5920, 6140 [Ken Coar]
3225 *) Tweak server/Makefile so that the rules for generating exports.c
3226 are compatible with make utilities which don't expand wildcards
3227 in a dependency list (e.g., OS/390 make, certain levels of GNU
3228 make). [Jeff Trawick]
3230 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
3232 *) Begin to sanitize the MPM configuration directives. Now, all
3233 MPMs use the same functions for all common MPM directives. This
3234 should make it easier to catch all bugs in these directives once.
3235 [Cody Sherr <csherr@covalent.net>]
3237 *) Close a major resource leak. Every time we had issued a
3238 graceful restart, we leaked a socket descriptor.
3241 *) Fix a problem with the new method code. We need to cast
3242 the 1 to an apr_int64_t or it will be treated as a 32-bit
3243 integer, and it will wrap after being shifted 32 times.
3244 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
3246 *) Fix a bug in mod_expires. Previous to this patch, if you
3247 told mod_expires to add 604800 seconds to the last-modified
3248 time, it actually added 604800 usec's to the last-modified time,
3249 so that when looking at the response it looked like nothing
3250 had been done. The root of the problem was that we always compute
3251 time in usec's, but we ask users to input sec's. This means we
3252 need to convert to usec's before using those values.
3255 *) The worker MPM now handles shutdown and restart requests. It
3256 definitely isn't perfect, but we do stop the servers correctly.
3257 The biggest problem right now is that SIGHUP causes the server to
3258 just die. [Ryan Bloom]
3260 Changes with Apache 2.0.23
3262 *) Use the prefork MPM by default on Unix. [various]
3264 *) Added a systray icon monitor application for Win32.
3265 [Mladen Turk <mturk@mappingsoft.com>]
3267 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3268 messages written to the rewrite log.
3269 [Richard Labennett <rlabenn@us.ibm.com>]
3271 *) All mod_autoindex query parsing is now quietly quashed with the
3272 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3273 still drops the column sort <a href>'s for the column headers, but
3274 IgnoreClient is required to ignore these Query options entirely.
3277 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3278 to allow the client to select plain, FancyIndexing or HTMLTable
3279 formatting, V=[0|1] to inhibit or enable version sorting, and
3280 P=pattern to return only specific files. The old Query Arguments
3281 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3282 as before), and O=A|D for ordering ascending or descending.
3285 *) Fixed an error in mod_include's directive parsing routines which
3286 caused #if, #elif, and #else expressions containing backslashes
3287 to be improperly evaluated. [Cliff Woolley]
3289 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3290 drop the icon column, SuppressRules to drop the <hr> elements,
3291 and HTMLTable to create rudimentary HTML table listings (implies
3292 FancyIndexing). [William Rowe]
3294 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3295 from Apache 1.3.15. This is needed for two reasons, first, given
3296 multiple machines within a server farm, ETags and Last-Modified
3297 stamps won't correspond from machine to machine, and second, many
3298 Unixes don't capture changes to the date or time stamp of existing
3299 files, since these don't modify the dirent itself. [William Rowe]
3301 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3302 and DirectoryWidth options from Apache 1.3.10.
3303 [William Rowe, Ken Coar]
3305 *) Eliminated FancyIndexing directive, deprecated early in Apache
3306 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3308 *) mod_autoindex now excludes any file names that would result in
3309 an error, other than a success or redirect. Also optimized
3310 the parent directory, always included except in the URI '/'.
3313 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3314 negotiated index pages, and prevent the server from defaulting
3315 to an autoindex of the directory. mod_negotiation will now die
3316 with a 500 Internal Error if it could match some filenames
3317 (e.g. for mod_dir) but none can be served. mod_negotation now
3318 refuses to serve any file with an extention that mod_mime doesn't
3319 recognize, and wasn't part of the request. [William Rowe]
3321 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3322 extension. This is already handled by multiviews, if the admin
3323 wishes to AddHandler .exe or define a content type handler and
3324 associate .exe files with that content type. Multiviews must be
3325 enabled to allow these to be served. [William Rowe]
3327 *) Speed up the server's response to a spike in incoming workload
3328 or restarts by assigning empty scoreboard slots to new processes
3329 when they are available. [Greg Ames]
3331 *) Add a handler to mod_includes.c. This handler is designed to
3332 implement the XbitHack directive. This can't be done with a
3333 fixup, because we need to check the content-type, which is
3334 only available in the handler phase. [Ryan Bloom]
3336 *) Make the includes filter check return codes from filters lower in
3337 the filter chain. If a lower level filter returns an error, then
3338 the request needs to stop immediately. This allows mod_include to
3339 stop parsing data once a lower filter recognizes an error.
3342 *) Add the ability to extend the methods that Apache understands
3343 and have those methods <limit>able in the httpd.conf. It uses
3344 the same bit mask/shifted offset as the original HTTP methods
3345 such as M_GET or M_POST, but expands the total bits from an int to
3346 an ap_int64_t to handle more bits for new request methods than
3347 an int provides. [Cody Sherr <csherr@covalent.net>]
3349 *) Fix broken mod_mime behavior in merging its arguments. Possible
3350 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
3352 *) Solve many mod_ssl porting issues (too many to detail) with
3353 help from the whole team, but most notably [Ralf S. Engelschall,
3354 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
3355 Doug MacEachern, William Rowe, Cliff Woolley]
3357 *) More stall fixes for the threaded & worker mpm's.
3358 Make mod_status output more accurate. Don't
3359 count workers in processes which aren't actively
3360 serving requests. [Greg Ames]
3362 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
3364 *) Add a single listener/multiple worker MPM. This MPM is
3365 definately not fully correct, but it allows us to solve many
3366 of the problems that exist in the threaded MPM. This is a
3367 modified version of the threaded MPM. [Ryan Bloom]
3369 *) Improve content generation throughout Apache, providing closer
3370 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
3371 Transitional specifications. [William Rowe]
3373 Changes with Apache 2.0.22
3375 *) Fix a problem where the threaded MPM stalls after restarts or
3376 segfaults. Also prevent multiple active processes from using
3377 the same scoreboard slot. [Greg Ames]
3379 *) Apache/Win32 now fills in the service description with Apache's
3380 server version string, including loaded and advertised modules.
3383 *) Improved support for the Win32 build, to recover gracefully from
3384 missing apr or apr-util directories or the awk interpreter,
3385 create the proper cgi-bin examples, including a test-cgi.bat, and
3386 fix the perl shebang line for printenv.pl, when installing from
3387 the build environment. [William Rowe]
3389 *) Fix a segfault in threaded.c caused by passing uninitialized
3390 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
3392 *) Use new APR number conversion functions to reduce CPU consumption
3393 when setting the content length, and in mod_log_config.
3396 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
3397 where HEAD response headers were being repeated twice for
3398 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
3399 problem in the http_header filter was exposed by the recent rewrite
3400 of the content_length filter. [Taketo Kabe, Bill Stoddard]
3402 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
3403 restarts. A garbage pointer to a vhost's server_rec from the
3404 previous generation was being left around under certain
3405 conditions. [Greg Ames]
3407 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
3408 used to appear as '(none', without the closing paren.
3409 [Günter Knauf <eflash@gmx.net>]
3411 *) Improve the exports generating awk script. In the past, we had
3412 work around problems in the awk script by avoiding some #if and
3413 #ifdefs. This has bitten us many times in generating the exports.c
3414 file. This improvement allows corrects the header file parsing.
3415 [Sander Striker <striker@apache.org>]
3417 Changes with Apache 2.0.21
3419 *) Resolve the Win32 htpasswd bug, where a file that existed would be
3420 overwritten, regardless of the -c flag.
3421 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
3423 *) Introduce connection sub-pools into ab. Truncating the lifetime
3424 of these allocations means that ab no longer perpetually grows
3425 its working set, running out of memory on large request attempts.
3428 *) Make scoreboard creation a hook. This allows management
3429 modules to have access to the scoreboard at the time that it is
3430 created, and at every restart request.
3431 [Cody Sherr <csherr@covalent.net>]
3433 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
3434 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
3435 daemon index actually used in the scoreboard. I also
3436 updated the pertinent calls. [Paul J. Reder]
3438 *) Win32: Prevent listening sockets from being inherited by
3439 the Apache child process, CGI scripts, rotatelog process
3440 etc. If the Apache child process segfaults, any processes
3441 that the child started are not reaped. Prior to this fix,
3442 these processes inherited the listening sockets which sometimes
3443 prevented the restarted Apache child process from accepting
3444 connections (ie, the server would hang).
3447 *) Provide vhost and request strings when ExtendedStatus is on.
3450 *) Fix some issues with the pod and prefork: check the pod *after*
3451 processing a connection so that a server processing a time-
3452 consuming request bails out as soon as practical; when the
3453 parent process wakes up a server process via connect(), use an
3454 APR timeout on the connect() so that we don't hang for a long
3455 time if there aren't server processes around to do accept().
3456 [Jeff Trawick, Greg Ames]
3458 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
3459 spends a lot of time in apr_table_get calls. Using the default
3460 httpd.conf, the tables for languages and charsets are somewhat
3461 large, so the time spent scanning them on each request is
3462 significant. Replacing the tables with hash tables provides
3463 a nice speedup. [Brian Pane <bpane@pacbell.net>]
3465 *) Add two functions to allow modules to access random parts of the
3466 scoreboard. This allows modules compiled for one MPM to access the
3467 scoreboard, even if it the server was compiled for another MPM.
3468 [Harrie Hazewinkel <harrie@covalent.net>]
3470 Changes with Apache 2.0.20
3472 *) Fix problem in content-length filter where the filter would
3473 buffer all the output from a CGI before sending any bytes
3474 down the filter stack to the network. This problem would cause
3475 significant memory consumption if the CGIs generated
3476 lots of bytes. [Bill Stoddard]
3478 *) Get non-blocking CGI pipe reads working with the bucket brigades.
3481 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
3484 *) Fix a bug in the threaded MPM that would cause it to kill off all
3485 workers immediately after starting if the number of workers started
3486 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
3488 Changes with Apache 2.0.19
3490 *) Fix problem with threaded MPM. The problem was that if each child
3491 process was busy serving a single long-lived request and the server
3492 was sent a graceful restart signal, the server would stop serving
3493 requests. This would happen because each child process would wait to
3494 die until the last thread was done, and the parent wouldn't spawn any
3495 new children until a process died. Now, the parent looks at the fact
3496 that the children are dying gracefully, and starts new children.
3497 Those new children only start enough threads to compliment the number
3498 of threads in the other child process that shares the same spot in
3499 the scoreboard. In this way, we make sure to never go over
3500 MaxClients. [Ryan Bloom]
3502 *) modified mod_negotiation and mod_autoindex to speed up by almost a
3503 factor of two on apr_dir_read()-enhanced platforms, such as Win32
3504 and OS2, by calling ap_sub_request_lookup_dirent() with the results
3505 already provided by apr_dir_read(). [William Rowe]
3507 *) mod_file_cache is now more robust to filtering and serves requests
3508 slightly more efficiently. [Cliff Woolley]
3510 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
3511 Module was calling ap_rwrite() followed by ap_rflush() but the
3512 served content was not being displayed in the browser. Inspection
3513 of the output stream revealed that the first data chunk was
3514 missing the trailing CRLF required by the RFC. [Bill Stoddard]
3516 *) apxs no longer generates ap_send_http_header() in the example handler
3518 *) Fix an ab problem which could cause a divide-by-zero exception
3519 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
3520 [Ian Holsman <ianh@cnet.com>]
3522 *) Solve case-insensitive platforms' confusion about negotiated
3523 filenames, allowing files of differnt case to match in choosing
3524 the document to serve. [William Rowe]
3526 *) Fix brokenness when ThreadsPerChild is higher than the built-in
3527 limit. We left ap_threads_per_child at the higher value which
3528 led to segfaults when doing certain scoreboard operations.
3531 *) Fix seg faults and/or missing output from mod_include. The
3532 default_handler was using the subrequest pool for files and
3533 MMAPs, even though the associated APR structures typically
3534 live longer than the subrequest. [Greg Ames]
3536 *) Extend mod_setenvif to support specifying regular expressions
3537 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
3538 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
3539 will cause HAVE_TS to be set if any of the request headers begins
3540 with "TS" and has a value that begins with any character in the
3541 set [a-z]. [Bill Stoddard]
3543 *) httpd children now re-bind themselves to a random CPU on
3544 multiprocessor systems on AIX via bindprocessor() in 2.0.
3545 [Victor J. Orlikowski]
3547 *) Fix htdigest. It would go into a loop in getline when adding
3548 a second user. [Bill Stoddard]
3550 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
3552 *) Automatically generate httpd.exp for AIX.
3553 DSOs now work again on AIX in 2.0
3554 [Victor J. Orlikowski]
3556 *) Add a new request hook, error_log. This phase allows modules
3557 to act on the error log string _after_ it has been written
3558 to the error log. The goal for this hook is to allow monitoring
3559 modules to send the error string to the monitoring agent.
3562 *) Modify mod_echo to make it use filters for input and output.
3563 [Ryan Morgan <rmorgan@covalent.net>]
3565 *) Extend mod_headers to support conditional driven Header
3566 add, append and set. Use SetEnvIf to set an envar and conditionally
3567 add/append/set headers based on this envar thusly:
3569 SetEnvIf TSMyHeader value HAVE_TSMyHeader
3570 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
3572 If the request contains header "TSMyHeader: value" then header
3573 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
3576 *) Extend mod_headers to support using format specifiers on Header
3577 add, append and set header values. Two format specifiers are supported:
3579 %t - reports, in UTC microseconds since the epoch, when the
3580 request was received.
3582 %D - reports the time, in microseconds, between when the request was
3583 received and the response sent.
3586 Header add MyHeader "This request served in %D microseconds. %t"
3588 results in a header being added to the response that looks like this:
3590 MyHeader: This request served in D=5438 microseconds. t=991424704447256
3594 *) Fix reset_filter(). We need to be careful how we remove filters.
3595 If we set r->output_filters to NULL, we also have to reset the
3596 connection's filters. [John Sterling]
3598 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
3600 *) Add a check to ap_die() to make sure the filter stack is sane and
3601 contains the correct basic filters when an error occurs. This fixes
3602 a problem where headers are not being sent on error. [John Sterling]
3604 *) New Header directive 'echo' option. "Header echo regex" will
3605 cause any headers received on the request that match regex to be
3606 echoed to (included in) the response headers.
3609 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
3610 This prevented the inclusion of apr_compat.h. PR #7773
3611 [Oleg Broytmann <phd@phd.pp.ru>]
3613 *) Moved util_uri to the apr-util library. This required a bunch of
3614 apr_name changes for the uri utility functions. [Justin Erenkrantz]
3616 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
3617 insert_filter phase so that other filters are not bypassed by default.
3620 *) Reimplement mod_headers as an output filter. mod_headers can now
3621 add custom headers to inbound requests using the RequestHeader directive
3622 and to responses using the same old Header directive. [Graham Leggett]
3624 Changes with Apache 2.0.18
3626 *) Fix command-line processing so that if a bad argument is specified
3627 Apache will exit. [Jeff Trawick]
3629 *) Change the make targets and rules to be consistent in all of the
3630 Apache-owned source trees. [Roy Fielding]
3632 *) Fix processing of the TRACE method. Previously we passed bogus
3633 parms to form_header_field() and it overlaid some vhost structures,
3634 resulting in a segfault in check_hostalias().
3635 [Greg Ames, Jeff Trawick]
3637 *) Win32: Add support for reliable piped logs. If the logging process
3638 goes down, Apache will automatically restart it. This function has
3639 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
3642 *) Do not start piped log processes during the config file
3643 preflight. This change also circumvents a problem on
3644 Windows where the rotatelog processes created during preflight
3645 was not getting cleaned up properly.
3648 *) add "Request Phase Participation" info to mod_info
3651 *) Make first phase changes to the scoreboard data structures in
3652 preparation for the rewriting of the scoreboard per my posted
3653 design notes. [Paul J. Reder]
3655 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
3656 and apr-util, allow it to be overridden by the configure command-line
3657 (default="--silent") and introduce LT_LDFLAGS to replace what we were
3658 formerly abusing as LTFLAGS. [Roy Fielding]
3660 *) Clean up the reporting of incorrect closing container tags.
3661 [Barrie Slaymaker <barries@slaysys.com>]
3663 *) Simplify the configure process by moving all libtool stuff to APR
3664 and moving hints.m4 inline. [Roy Fielding]
3666 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
3667 of functions used by mod_proxy for export in the DLL
3668 [Ian Holsman <IanH@cnet.com>]
3670 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
3671 request body from its stdin but no reqest body is being written to
3672 the cgi. [Jeff Trawick]
3674 *) mod_log_config: %c connection status incorrectly logged
3675 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
3678 *) Get mod_cern_meta working under Windows
3681 *) Create Files, and thus MMAPs, out of the request pool, not the
3682 connection pool. This solves a small resource leak that had us
3683 not closing files until a connection was closed. In order to do
3684 this, at the end of the core_output_filter, we loop through the
3685 brigade and convert any data we have into a single HEAP bucket
3686 that we know will survive clearing the request_rec.
3687 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
3690 *) Completely revamp configure so that it preserves the standard make
3691 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
3692 the configure additions to EXTRA_* variables. Also, allow the user
3693 to specify NOTEST_* values for all of the above, which eliminates the
3694 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
3695 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
3696 avoid pointless duplications. Fix the order in which flags are given
3697 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
3698 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
3699 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
3700 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
3702 *) Get mod_tls to compile/work better on Windows. PR #7612
3703 [Bernhard Schrenk <b.schrenk@improx.com>]
3705 *) Fix shutdown/restart hangs in the threaded MPM.
3706 [Jeff Trawick, Greg Ames, Ryan Bloom]
3708 *) Removed the keptalive boolean from conn_rec because it is now only
3709 used by a single routine and can be replaced by a local variable.
3710 [Greg Stein, Ryan Bloom, Roy Fielding]
3712 *) Patch prefork to put enough of the signal processing back in so that
3713 signals are all handled properly now. The previous patch fixed the
3714 deadlock race condition, but broke the user directed signal handling.
3715 This fixes it to work the way it did before my previous prefork patch
3716 (primarily, SIGTERM is now working).
3718 *) Change how input filters decide how much data is returned to the
3719 higher filter. We used to use a field in the conn_rec, with this
3720 change, we use an argument to ap_get_brigade to determine how much
3721 data is retrieved. [Ryan Bloom]
3723 *) Fix seg fault at start-up introduced by Ryan's change to enable
3724 modules to specify their own logging tags. mod_log_config
3725 registers an optional function, ap_register_log_handler().
3726 ap_register_log_handler() was being called by http_core before
3727 the directive hash table was created. This patch creates the
3728 directive hash table before ap_register_log_handler() is
3729 registered as an optional function.
3730 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
3732 *) Add ap_set_int_slot() function
3733 [John K. Sterling <sterling@covalent.net>]
3735 *) Under certain circumstances, Apache did not supply the
3736 right response headers when requiring authentication.
3737 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
3738 (This is a port of the change that went into Apache 1.3.19.)
3740 *) Allow modules to specify their own logging tags. This basically
3741 allows a module to tell mod_log_config that when %x is encountered
3742 a specific function should be called. Currently, x can be any single
3743 character. It may be more useful to make this a string at some point.
3746 Changes with Apache 2.0.17
3748 *) If a higher-level filter handles the the byterange aspects of a
3749 request, then the byterange filter should not try to redo the
3750 work. The most common case of this happening, is a byterange
3751 request going through the proxy, and the origin server handles
3752 the byterange request. The proxy should ignore it.
3753 [Graham Leggett <minfrin@sharp.fm>]
3755 *) Changed the threaded mpm to have child_main join to each of the
3756 worker threads to make sure the kids are all gone before child_main
3757 exits after a signal (cleanup from perform_idle_server_maintenance).
3758 This is an extension of Ryans recent commit to make the child_main
3761 *) Add more options to the ap_mpm_query function. This also allows MPMs to
3762 report if their threads are dynamic or static. Finally, this also
3763 implements a new API, ap_show_mpm, which returns the MPM that was
3764 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
3766 *) Do not install the binaries from the support directory twice.
3767 [jun-ichiro hagino <itojun@iijlab.net>]
3769 *) The ap_f* functions should flush data to the filter that is passed
3770 in, not the the filter after the one passed in.
3771 [Ryan Morgan <rmorgan@covalent.net>]
3773 *) Make ab work again by changing its native types to apr types and formats.
3774 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3776 *) Move the byterange filter and all of the supporting functions back
3777 to the HTTP module. The byterange filter turned out to be very
3778 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
3780 *) Make clean, distclean, and extraclean consistently according to the
3781 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
3783 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
3784 This may have been causing problems stopping processes in the threaded
3787 *) Fix content-length in mod_negotiation to a long int representation.
3790 *) Remove BindAddress from the default config file.
3791 [giles@nemeton.com.au]
3793 *) Allow module authors to add a module to their Apache build using
3794 --with-module, without re-running buildconf. The syntax is:
3795 --with-module=module_type:/path/to/module.c
3796 The configure script will copy the module.c file to
3797 modules/module_type, and it will be added to the relevant Makefiles.
3798 currently, this only works for static modules. [Ryan Bloom]
3800 *) Changes required to make prefork clean up idle children properly.
3801 There was a window during which a starting worker deadlocks when
3802 an idle cleanup arrives before it completes init. Apache then keeps
3803 trying to cleanup the same deadlocked worker forever (until higher
3804 pids come along, but it still will never reduce below the deadlocked
3805 pid). Thus the number of children would not reduce to the correct
3806 idle level. [Paul J. Reder]
3808 Changes with Apache 2.0.16
3810 *) Change the default installation directory to /usr/local/apache2,
3811 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
3813 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
3816 *) Get MaxRequestsPerChild working with the Windows MPM.
3819 *) Make generic hooks to work, with mod_generic_hook_import/export
3820 experimental modules. [Ben Laurie, Will Rowe]
3822 *) Fix segfaults for configuration file syntax errors such as
3823 "<Directory>" followed by "</Directory" and
3824 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
3826 *) Cleanup the --enable-layout option of configure. This makes
3827 us use a consistent location for the config.layout file, and it
3828 makes configure more portable.
3829 [jun-ichiro hagino <itojun@iijlab.net>]
3831 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
3832 csv/gnuplot format, rudimentary ssl support and various other tweaks
3833 to make results more true to what is measured. The upshot of this it
3834 turns out that 'ab' has often underreported the true performance of
3835 apache. Often by a order of magnitude :-) See talk/paper of Sander
3836 Temme at April ApacheCon 2001 for details.
3837 [Dirk-Willem van Gulik]
3839 *) Clean up mod_cgid's temporary request pool. Besides fixing a
3840 storage leak this ensures that some unnecessary pipes are closed.
3843 *) Performance: Add quick_handler hook. This hook is called at the
3844 very beginning of the request processing before location_walk,
3845 translate_name, etc. This hook is useful for URI keyed content
3846 caches like Mike Abbott's Quick Shortcut Cache.
3849 *) top_module global variable renamed to ap_top_module [Perl]
3851 *) Move ap_set_last_modified to the core. This is a potentially
3852 controversial change, because this is kind of HTTP specific. However
3853 many protocols should be able to take advantage of this kind of
3854 information. I expect that headers will need one more layer of
3855 indirection for multi-protocol work, but this is a small step in
3856 the right direction. [Ryan Bloom]
3858 *) Enable mod_status by default. This matches what Apache 1.3 does.
3861 *) Add a ScriptSock directive to the default config file. This is
3862 only enabled when mod_cgid is used.
3863 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
3865 Changes with Apache 2.0.15
3867 *) Untangled the buildconf script and eliminated the need for build's
3868 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
3869 libtool muck that is now under srclib/apr/build. [Roy Fielding]
3871 *) Win32: Don't accept more connections than we have worker threads
3875 *) Fix bug in the Unix threaded.c MPM that allowed child processes
3876 to fork() new child processes.
3879 *) SECURITY: Fix a major security problem with double-reverse lookup
3880 checking. Previously, a client connecting over IPv4 would not be
3881 matched properly when the server had an IPv6 listening socket.
3882 PR #7407 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
3884 *) Change the way the beos MPM handles polling to allow it to stop and
3885 restart. Problem was the sockets being polled were being reset by
3886 the select call, so once it had accepted a connection it was no
3887 longer listening on the UDP socket we use for shutdown instructions.
3888 APR needs to be altered, patch on it's way. [David Reid]
3890 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
3891 on error exit from ap_getline(). Some other code got upset because
3892 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
3894 *) Handle ap_discard_request_body() being called more than once.
3895 [Greg Ames, Jeff Trawick]
3897 *) Get rid of an inadvertent close of file descriptor 2 in
3898 mod_mime_magic. [Greg Ames, Jeff Trawick]
3900 *) Add a hook, create_request. This hook allows modules to modify
3901 a request while it is being created. This hook is called for all
3902 request_rec's, main request, sub request, and internal redirect.
3903 When this hook is called, the the r->main, r->prev, r->next
3904 pointers have been set, so modules can determine what kind of
3905 request this is. [Ryan Bloom]
3907 *) Cleanup the build process a bit more. The Apache configure
3908 script no longer creates its own helper scripts, it just
3910 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
3912 *) Stop the forced downgrade of the connection to HTTP/1.0 for
3913 proxy requests. [Graham Leggett]
3915 *) Avoid using sscanf to determine the HTTP protocol number in
3916 the common case because sscanf is a performance hog. From
3917 Mike Abbot's Accelerating Apache patch number 6.
3918 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
3920 *) SECURITY: Fix a security exposure in mod_access. Previously when
3921 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
3922 were not evaluated properly (PR #7407). Also, add the ability to
3923 specify IPv6 address strings with optional prefix length on Allow
3924 and Deny. [Jeff Trawick]
3926 *) Enhance rotatelogs so that a UTC offset can be specified, and
3927 the logfile name can be formatted using strftime(3). (Brought
3928 forward from 1.3.) [Ken Coar]
3930 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
3931 DuplicateHandle on an IOCompletionPort (a practice which
3932 MS "discourages"). The new model does not rely on associating
3933 the completion port with the listening sockets, thus the
3934 completion port can be completely managed within the child
3935 process. A dedicated thread accepts connections off the network,
3936 then calls PostQueuedCompletionStatus() to wake up worker
3937 threads blocked on the completion port.
3940 *) Bring forward the --suexec-umask option which allows the
3941 builder to preset the umask for suexec processes. [Ken Coar]
3943 *) Add a -V flag to suexec, which causes it to display the
3944 compile-time settings with which it was built. (Only
3945 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
3947 *) Mod_include should always unset the content-length if the file is
3948 going to be passed through send_parsed_content. There is no to
3949 determine if the content will change before actually scanning the
3950 entire content. It is far safer to just remove the C-L as long
3951 as we are scanning it. [Ryan Bloom]
3953 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
3954 request and not Proxy-Authenticate.
3955 [Graham Leggett <minfrin@sharp.fm>]
3957 Changes with Apache 2.0.14
3959 *) Fix content-length computation. We ONLY compute a content-length if
3960 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
3961 or we already have all the data. [Ryan Bloom]
3963 *) Report unbounded containers in the config file. Previously, a typo
3964 in the </container> directive could result in the rest of the config
3965 file being silently ignored, with undesired defaults used.
3968 *) Make the old_write filter use the ap_f* functions for the buffering.
3971 *) Move more code from the http module into the core server. This
3972 is core code, basically the default handler, the default input
3973 and output filters, and all of the core configuration directives.
3974 All of this code is required in order for the server to work, with or
3975 without HTTP. The server is closer to working without the HTTP
3976 module, although there is still more to do. [Ryan Bloom]
3978 *) Fix a number of SGI compile warnings throughout the server. Fix some
3979 bad parameters to apr_bucket_read(). Fix a bad statement in
3980 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
3981 consistently; we were mixing apr_time_t and time_t in invalid ways
3982 before. In load_file(), call apr_dso_error() instead of
3983 apr_strerror() so that we get a more specific string on some platforms.
3984 PR #6980 [Jeff Trawick]
3986 *) Allow modules to query the MPM about it's execution profile. This
3987 query API can and should be extended in the future, but for now,
3988 max_daemons, and threading or forking is a very good start.
3989 [Jon Travis <jtravis@covalent.net>]
3991 *) Modify mod_include to send blocks of data no larger than 9k.
3992 Without this, mod_include will wait until the whole file is parsed,
3993 or the first tag is found to send any data to the client.
3994 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3996 *) Fix mod_info, so that <Directory> and <Location> directives are
3997 not displayed twice when displaying the current configuration.
3998 [Ryan Morgan <rmorgan@covalent.net>]
4000 *) Add config directives to override DEFAULT_ERROR_MSG and
4001 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
4002 [Dan Rench <drench@xnet.com>]
4004 *) Get mod_info building and loading on Win32. [William Rowe]
4006 *) Begin to move protocol independant functions out of mod_http. The goal
4007 is to have only functions that are HTTP specific in the http directory.
4010 Changes with Apache 2.0.13
4012 *) Don't assume that there will always be multiple calls to the byterange
4013 filter. It is possible that we will need to do byteranges with only
4014 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
4016 *) Move the error_bucket definition from the http module to the
4017 core server. Every protocol will need this ability, not just
4020 Changes with Apache 2.0.12
4022 *) Modify mod_file_cache to save pre-formatted strings for
4023 content-length and last-modified headers for performance.
4024 [Mike Abbot <mja@trudge.engr.sgi.com>]
4026 *) Namespace protect IOBUFSIZ since it is exposed in the API.
4027 [Jon Travis <jtravis@covalent.net>]
4029 *) Use "Basic" authentication instead of "basic" in ab, as the spec
4030 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
4032 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
4033 without ever filling it out. This fixes PR 7271.
4034 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
4035 Cliff Woolley <cliffwoolley@yahoo.com>]
4037 *) Add a couple of GCC attribute tags to printf style functions.
4038 [Jon Travis <jtravis@covalent.net>]
4040 *) Add the correct language tag for interoperation with the Taiwanese
4041 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
4043 *) Migrate the perchild MPM to use the new apr signal child, and
4044 APR thread functions. [Ryan Bloom]
4046 *) Close one copy of the CGI's stdout before creating the new process.
4047 The CGI will still have stdout, because we have already dup'ed it.
4048 This keeps Apache from waiting forever to send the results of a CGI
4049 process that has forked a long-lived child process.
4050 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
4052 *) Remove the rest of the pthreads functions from the threaded MPM.
4053 This requires the APR support for a signal thread that was just
4056 *) Make mod_dir use a fixup for sending a redirect to the browser.
4057 Before this, we were using a handler, which doesn't make much
4058 sense, because the handler wasn't generating any data, it would
4059 either return a redirect error code, or DECLINED. This fits the
4060 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
4062 *) Make the threaded MPM use APR threads instead of pthreads.
4065 *) Get mod_tls to the point where it actually appears to work in all cases.
4068 *) implement --enable-modules and --enable-mods-shared for "all" and
4069 "most". [Greg Stein]
4071 *) Move the threaded MPM to use APR locks instead of pthread locks.
4074 *) Rename mpmt_pthread to threaded. This is more in line with the
4075 fact that mpmt_pthread shouldn't be using pthreads directly, and
4076 it is a smaller name that doesn't tie into anything.
4079 *) Rename the module structures so that the exported symbol matches
4080 the file name, and it is easier to automate the installation
4081 process (generating LoadModule directives from the module filenames).
4084 *) Remove the coalesce filter. With the ap_f* functions, this filter
4085 is no longer needed. [Ryan Bloom]
4087 Changes with Apache 2.0.11
4089 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
4090 added feature of allowing a uid/gid per child process. If no
4091 uid/gid is specified, then Perchild behaves exactly like dexter.
4094 *) Get perchild building again. [Ryan Bloom]
4096 *) Don't disable threads just because we are using the prefork MPM.
4097 If somebody wants to compile without threads, they must now add
4098 --disable-threads to the configure command line. [Ryan Bloom]
4100 *) Begin to move the calls to update_child_status into common code, so
4101 that each individual MPM does not need to update the scoreboard itself.
4104 *) Allow mod_tls to compile under Unix boxes where openssl has been
4105 installed to the system include files.
4106 [Gomez Henri <new-httpd@slib.fr>]
4108 *) Cleanup the mod_tls configure process. This should remove any need
4109 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
4110 configure doesn't check that yet. [Ryan Bloom]
4112 *) Add a very early prototype of SSL support (in mod_tls.c). It is
4113 vital that you read modules/tls/README before attempting to build
4116 *) Fix a potential seg fault on all platforms. David Reid fixed this
4117 on BEOS, but the problem could happen anywhere, so we don't want
4118 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
4120 *) Add new LogFormat directive, %D, to log time it takes to serve a
4121 request in microseconds. [Bill Stoddard]
4123 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
4124 SetOutputFilter. This corresponds nicely with the other Set
4125 directives, which operate on containers while the Add* directives
4126 tend to work directly on extensions. [Ryan Bloom]
4128 *) Cleanup the header handling a bit. This uses the apr_brigade_*
4129 functions for the buffering so that we don't need to compute
4130 the length of the headers before we actually create the header
4131 buffer. [Ryan Bloom]
4133 *) Allow filters to buffer data using the ap_f* functions. These have
4134 become macros that resolve directly to apr_brigade_*.
4137 *) Get the Unix MPM's to do a graceful restart again. If we are going
4138 to register a cleanup with ap_cleanup_scoreboard, then we have to
4139 kill the cleanup with the same function, and that function can't be
4140 static. [Ryan Bloom]
4142 *) Install all required header files. Without these, it was not
4143 possible to compile some modules outside of the server.
4146 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
4147 forward from 1.3 to 2.0, we missed a single line, which broke regex
4148 aliases. [Ryan Bloom]
4150 *) We have a poor abstraction in the protocol. This is a temporary
4151 hack to fix the bug, but it will need to be fixed for real. If
4152 we find an error while sending out a custom error response, we back
4153 up to the first non-OK request and send the data. Then, when we send
4154 the EOS from finalize_request_protocol, we go to the last request,
4155 to ensure that we aren't sending an EOS to a request that has already
4156 received one. Because the data is sent on a different request than
4157 the EOS, the error text never gets sent down the filter stack. This
4158 fixes the problem by finding the last request, and sending the data
4159 with that request. [Ryan Bloom]
4161 *) Make the server status page show the correct restart time, and
4162 thus the proper uptime. [Ryan Bloom]
4164 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
4165 should reduce the amount of duplicate code that is required to
4166 create CGI processes.
4167 [Paul J. Reder <rederpj@raleigh.ibm.com>]
4169 *) ap_new_connection() closes the socket and returns NULL if a socket
4170 call fails. Usually this is due to a connection which has been
4171 reset. [Jeff Trawick]
4173 *) Move the Apache version information out of httpd.h and into release.h.
4174 This is in preparation for the first tag with the new tag and release
4175 system. [Ryan Bloom]
4177 *) Begin restructuring scoreboard code to enable adding back in
4178 the ability to use IPC other than shared memory.
4179 Get mod_status working on Windows again. [Bill Stoddard]
4181 *) Make mod_status work with 2.0. This will work for prefork,
4182 mpmt_pthread, and dexter. [Ryan Bloom]
4184 *) Correct a typo in httpd.conf.
4185 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
4187 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
4189 *) Get the correct IP address if ServerName isn't set and we can't
4190 find a fully-qualified domain name at startup.
4191 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
4193 *) Make mod_cgid work with SuExec. [Ryan Bloom]
4195 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
4196 'extra' stat's for user/group since they should never occur, and now
4197 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
4198 volumes. [William Rowe]
4200 *) Adopt apr features to simplify mod_includes. This changes the
4201 behavior of the USER_NAME variable, unknown uid's are now reported
4202 as USER_NAME="<unknown>" rather than the old user#000 result.
4203 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
4205 *) Adopt apr features for simplifing mod_userdir, and accept the new
4206 Win32/OS2 exceptions without hiccuping. [William Rowe]
4208 *) Replace configure --with-optim option by using and saving the
4209 environment variable OPTIM instead. This is needed because configure
4210 options do not support multiple flags separated by spaces.
4213 *) Fix some byterange handling. If we get a byte range that looks like
4214 "-999999" where that is past the end of the file, we should return
4215 a PARTIAL CONTENT status code, and return the whole file as one big
4216 byterange. This matches the 1.3 handling now. [Ryan Bloom]
4218 *) Make the error bucket a real meta-data bucket. This means that the
4219 bucket length is 0, and a read returns NULL data. If one of these
4220 buckets is passed down after the headers are sent, this data will
4221 just be ignored. [Greg Stein]
4223 *) The prefork MPM wasn't killing child processes correctly if a restart
4224 signal was received while the process was serving a request. The child
4225 process would become the equivalent of a second parent process. If
4226 we break out of the accept loop, then we need to do die after cleaning
4227 up after ourselves. [Ryan Bloom]
4229 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
4230 restarts. [Ryan Bloom]
4232 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
4233 the most optimal APR_FINFO_wanted bits. This spares Win32 from
4234 performing very expensive owner, group and permission lookups
4235 and allows the server to function until these apr_finfo_t fields
4236 are implemented under Win32. [William Rowe]
4238 *) Support for typedsafe optional functions - that is functions exported by
4239 optional modules, which, therefore, may or may not be present, depending
4240 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
4241 for sample code. [Ben Laurie]
4243 *) filters can now report an HTTP error to the server. This is done
4244 by sending a brigade where the first bucket is an error_bucket.
4245 This bucket is a simple bucket that stores an HTTP error and
4246 a string. Currently the string is not used, but it may be needed
4247 to output an error log. The http_header_filter will find this
4248 bucket, and output the error text, and then return
4249 AP_FILTER_ERROR, which informs the server that the error web page
4250 has already been sent. [Ryan Bloom]
4252 *) If we get an error, then we should remove all filters except for
4253 those critical to serving a web page. This fixes a bug, where
4254 error pages were going through the byterange filter, even though
4255 that made no sense. [Ryan Bloom]
4257 *) Relax the syntax checking of Host: headers in order to support
4258 iDNS. PR#6635 [Tony Finch]
4260 *) Cleanup the byterange filter to use the apr_brigade_partition
4261 and apr_bucket_copy functions. This removes a lot of very messy
4262 code, and hopefully makes this filter more stable.
4265 *) Remove AddModule and ClearModuleList directives. Both of these
4266 directives were used to ensure that modules could be enabled
4267 in the correct order. That requirement is now gone, because
4268 we use hooks to ensure that modules are in the correct order.
4271 *) When SuExec is specified, we need to add it to the list of
4272 targets to be built. If we don't, then any changes to the
4273 configuration won't affect SuExec, unless 'make suexec' is
4274 specifically run. [Ryan Bloom]
4276 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4277 the APR_XTHREAD argument to open a file for consumption by
4278 parallel threads on win32. [William Rowe]
4280 *) Correct a bug in determining when we follow symlinks. The code
4281 expected a stat -1 result, not an apr_status_t positive error.
4282 Also check if the APR_FINFO_USER fields are valid before we
4283 follow the link. [William Rowe]
4285 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4286 mpm_common.c. These functions are only valid on some platforms,
4287 so they should not be in the main-line code. [Ryan Bloom]
4289 *) Remove ap_chdir_file(). This function is not thread-safe,
4290 and nobody is currently using it. [Ryan Bloom]
4292 *) Do not try to run make depend if there are no .c files in the
4293 current directory, doing so makes `make depend` fail.
4296 *) Update highperformance.conf to work with either prefork or
4297 pthreads mpms. [Greg Ames]
4299 *) Stop checking to see if this is a pipelined request if we know
4300 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4301 This keeps us from making an extra read call when serving a 1.0
4302 request. [Ryan Bloom and Greg Stein]
4304 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4305 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4306 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4308 *) Fix the RFC number mentioned when complaining about a missing
4309 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
4311 *) Fix an endless loop in ab which occurred when ab was posting
4312 and the server dropped the connection unexpectedly.
4315 *) Fix a segfault while handling request bodies in ap_http_filter().
4316 This problem has been seen with mod_dav usage as well as with
4317 requests where the body was just being discarded. [Jeff Trawick]
4319 *) Some adjustment on the handling and automatic setting (via
4320 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4321 add the capability to specify flags (NOTEST_CFLAGS and
4322 NOTEST_LDFLAGS) which are used to compile Apache, but
4323 not used during the configuration process. Useful for
4324 flags like "-Werror". [Jim Jagielski]
4326 *) Stop using environment variables to force debug mode or
4327 no detach. We now use the -D command line argument to
4328 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4329 [Greg Stein, Ryan Bloom]
4331 *) Change handlers to use hooks. [Ben Laurie]
4333 *) Stop returning copies of filenames from both apr_file_t and
4334 apr_dir_t. We pstrdup the filenames that we store in the
4335 actual structures, so we don't need to pstrdup the strings again.
4338 *) mod_cgi: Fix some problems where the wrong error value was being
4339 traced. [Jeff Trawick]
4341 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
4344 *) Add generic hooks. [Ben Laurie]
4346 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
4348 *) Fix a segfault caused by mod_ext_filter when the external filter
4349 program does not exist. [Jeff Trawick]
4351 *) Fix an output truncation error when on an HTTP >= 1.0 request an
4352 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
4353 was served through mod_charset_lite (or anything else that would
4354 create a transient bucket in this size range). ap_bucket_make_heap()
4355 silently failed (fixed), transient_setaside() discovered it, but
4356 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
4358 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
4359 is that some browsers send extra lines at the end of POST requests, and
4360 we don't want to delay sending data back to the user just because the
4361 browser isn't well behaved. [Ryan Bloom]
4363 *) Get SuEXEC working again. We can't send absolute paths to suExec
4364 because it refuses to execute those programs. SuEXEC also wasn't
4365 always recognizing configuration changes made using the autoconf
4368 *) Allow the buildconf process to find the config.m4 files in the correct
4369 order. Basically, we can now name config.m4 files as config\d\d.m4,
4370 and we will sort them correctly when inserting them into the build
4371 process. [Ryan Bloom]
4373 *) Get mod_cgid to use apr calls for creating the actual CGI process.
4374 This also allows mod_cgid to use ap_os_create_priviledged_process,
4375 thus allowing for SuExec execution from mod_cgid. Currently, we do
4376 not support everything that standard SuExec supports, but at least
4377 it works minimally now. [Ryan Bloom]
4379 *) Allow SuExec to be configured from the ./configure command line.
4382 *) Update some of the docs in README and INSTALL to reflect some of
4383 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
4385 *) If we get EAGAIN returned from the call to apr_sendfile, then we
4386 need to call sendfile again. This gets us serving large files
4387 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
4389 *) Get the support programs building cleanly again.
4390 [Cliff Woolley <cliffwoolley@yahoo.com>]
4392 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
4393 current directory logic now backs up over bin/ to determine the
4394 server root from the Apache.exe path.
4396 *) Apache/Win32 now follows the standard conventions of mod_foo.so
4397 loadable modules, dynamic libs are all named libfoo.dll, and the
4398 makefile.win populates the include, lib and libexec directories.
4400 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
4401 Apache gets IPv6 listening sockets by default. Additionally, the
4402 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
4403 numeric address strings (e.g., "Listen [fe80::1]:8080").
4406 *) Modify the install directory layout. Modules are now installed in
4407 modules/. Shared libraries should be installed in libraries/, but
4408 we don't have any of those on Unix yet. All install directories
4409 are modifyable at configure time. [Ryan Bloom]
4411 *) Install all header files in the same directory on Unix. [Ryan Bloom]
4413 *) Get the functions in server/linked into the server, regardless of
4414 which modules linked into the server. This uses the same hack
4415 for Apache that we use for APR and apr-util to ensure all of the
4416 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
4417 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
4418 the scripts a bit easier.
4421 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
4422 on the query, and remove IPv4 dependencies. [Jeff Trawick]
4424 *) Get all of the auth modules to the point that they will install and
4425 be loadable into the server. Our new build/install mechanism expects
4426 that all modules will have a common name format. The auth modules
4427 didn't use that format, so we didn't install them properly.
4430 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
4431 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
4433 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
4435 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
4436 after the end of the response. [Ryan Bloom]
4438 *) Get byterange requests working with responses that do not have a
4439 content-length. Because of the way byterange requests work, we have to
4440 have all of the data before we can actually do the byterange, so we
4441 can compute the content-length in the byterange filter.
4444 *) Get exe CGI's working again on Windows.
4447 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
4448 they keep track of whether or not their post config hook has been
4449 called before. Instead of a static variable (which is replaced when
4450 the DSO is loaded a second time), use userdata in the process pool.
4453 Changes with Apache 2.0a9
4455 *) Win32 now requires perl to complete the final install step for users
4456 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
4457 and installs the conf, htdocs and htdocs/manual directories.
4460 *) Make mod_include use a hash table to associate directive tags with
4461 functions. This allows modules to implement their own SSI tags easily.
4462 The idea is simple enough, a module can insert it's own tag and function
4463 combination into a hash table provided by mod_include. While mod_include
4464 parses an SSI file, when it encounters a tag in the file, it does a
4465 hash lookup to find the function that implements that tag, and passes
4466 all of the relevant data to the function. That function is then
4467 responsible for processing the tag and handing the remaining data back
4468 to mod_include for further processing.
4469 [Paul J. Reder <rederpj@raleigh.ibm.com>]
4471 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
4472 fewer parameters: the local and remote socket addresses were removed
4473 from the parameter list because all required information is available
4474 via the APR socket. [Jeff Trawick]
4476 *) Distribution directory structure reorganized to reflect a
4477 normal source distribution with external install targets.
4480 *) The MPMs that need multiple segments of shared memory now create
4481 two apr_shmem_t variables, one for each shared memory allocation.
4482 the problem is that we can't determine how much memory will be required
4483 for shared memory allocations once we try to allocate more than one
4484 variable. The MM code automatically aligns the shared memory allocations,
4485 so we end up needing to pad the amount of shared memory we want based
4486 on how many variables will be allocated out of the shared memory segment.
4487 It is just easier to create a second apr_shmem_t variable, and two
4488 shmem memory blocks.
4491 *) Cleanup the export list a bit. This creates a single unified list of
4492 functions exported by APR. The export list is generated at configure
4493 time, and that list is then used to generate the exports.c file.
4494 Because of the way the export list is generated, we only export those
4495 functions that are valid on the platform we are building on.
4498 *) Enable logging the cookie with mod_log_config
4499 [Sander van Zoest <sander@covalent.net>]
4501 *) Fix a segfault in mod_info when it reaches the end of the configuration.
4504 *) Added lib/aputil/ as a placeholder for utility functions which are not
4505 specific to the Apache HTTP Server (but do not make sense with APR).
4506 The first utility is "apu_dbm": a set of functions to work with DBM
4507 files. This first version can be compiled for SDBM or GDBM databases.
4510 *) Complete re-write of mod_include. This makes mod_include a filter that
4511 uses buckets directly. This has now served the FAQ correctly.
4512 [Paul Reder <rederpj@raleigh.ibm.com>]
4514 *) Allow modules to specify the first filter in a sub_request when
4515 making the sub_request. This keeps modules from having to change the
4516 output_filter immediately after creating the sub-request, and therefore
4517 skip the sub_req_output_filter. [Ryan Bloom]
4519 *) Update ab to accept URLs with IPv6 literal address strings (in the
4520 format described in RFC 2732), and to build Host header fields in
4521 the same format. This allows IPv6 literal address strings to be
4522 used with ab. This support has been tested against Apache 1.3 with
4523 the KAME patch, but Apache 2.0 does not yet work with this format
4524 of the Host header field. [Jeff Trawick]
4526 *) Accomodate an out-of-space condition in the piped logs and the
4527 rotatelogs.c code, and no longer churn log processes for this
4528 condition. [Victor J. Orlikowski]
4530 *) Add support for partial writes with apr_sendfile() to core_output_filter.
4533 Changes with Apache 2.0a8
4535 *) Add a directive to mod_mime so that filters can be associated with
4539 *) Get multi-views working again. We were setting the path_info
4540 field incorrectly if we couldn't find the specified file.
4543 *) Fix 304 processing. The core should never try to send the headers
4544 down the filter stack. Always, just setup the table in the request
4545 record, and let the header filter convert it to data that is ready
4549 *) More fixes for the proxy. There are still bugs in the proxy code,
4550 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
4554 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
4557 *) APR: Add new apr_getopt_long function to handle long options.
4558 [B. W. Fitzpatrick <fitz@red-bean.com>]
4560 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
4561 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
4562 hostname resolution/address string parsing and building
4563 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
4564 of one of the apr_sockaddr_t structures for a socket. Change
4565 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
4567 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
4568 I have proxied pages with it, cleanup will commence soon.
4571 *) Make the proxy work with filters. This isn't perfect, because we
4572 aren't dealing with the headers properly. [Ryan Bloom]
4574 *) Do not send a content-length iff the C-L is 0 and this is a head
4575 request. [Ryan Bloom]
4577 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
4578 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
4580 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
4582 *) Get the default_handler to stop trying to deal with HEAD requests.
4583 The idea is to let the content-length filter compute the C-L before
4584 we try to send the data. If we can get the C-L correctly, then we
4585 should send it in the HEAD response.
4588 *) The Header filter can now determine if a body should be sent based
4589 on r->header_only. The general idea of this is that if we delay
4590 deciding to send the body, then we might be able to compute the
4591 content-length correctly, which will help caching proxies to cache
4592 our data better. Any handler that doesn't want to try to compute
4593 the content-length can just send an EOS bucket without data and
4594 everything will just work.
4597 *) Add the referer to the error log if one is available.
4598 [Markus Gyger <mgyger@itr.ch>]
4600 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
4601 change, the root of the configuration tree has been exposed to modules
4603 [Ryan Morgan <rmorgan@covalent.net>]
4605 *) Get the core_output_filter to use the bucket interface directly.
4606 This keeps us from calling the content-length filter multiple times
4607 for a simple static request.
4610 *) We are sending the content-type correctly now.
4611 [Ryan Bloom and Will Rowe]
4613 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
4614 a bogus bytes-sent value when the only thing being sent was trailers
4615 and writev() returned an error (or EAGAIN). [Jeff Trawick]
4617 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
4618 hints file to determine which platforms define
4619 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
4622 *) APR: add apr_get_home_directory() [Jeff Trawick]
4624 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
4626 *) Not all platforms have INADDR_NONE defined by default. Apache
4627 used to make this check and define INADDR_NONE if appropriate,
4628 but APR needs the check too, and I suspect other applications will
4629 as well. APR now defines APR_INADDR_NONE, which is always a valid
4630 value on all platforms.
4631 [Branko Èibej <brane@xbc.nu>]
4633 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
4634 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
4636 *) Relax the syntax checking of Host: headers in order to support
4637 iDNS. PR#6635 [Tony Finch]
4639 *) When reading from file buckets we convert to an MMAP if it makes
4640 sense. This also simplifies the default handler because the
4641 default handler no longer needs to try to create MMAPs.
4644 *) BUFF has been removed from the main server. The BUFF code will remain
4645 in the code until it has been purged from the proxy module as well.
4648 *) Byteranges have been completely re-written to be a filter. This
4649 has been tested, and I believe it is working correctly, but it could
4650 doesn't work for the Adobe Acrobat plug-in. The output almost matches
4651 the output from 1.3, the only difference being that 1.3 includes
4652 a content-length in the response, and this does not.
4655 *) APR read/write functions and bucket read functions now operate
4656 on unsigned integers, instead of signed ones. It doesn't make
4657 any sense to use signed ints, because we return the error codes,
4658 so if we have an error we should report 0 bytes read or written.
4661 *) Always compute the content length, whether it is sent or not.
4662 The reason for this, is that it allows us to correctly report
4663 the bytes_sent when logging the request. This also simplifies
4664 content-length filter a bit, and fixes the actual byte-reporing
4665 code in mod_log_config.c
4668 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
4669 it says, because it was only used by EOS and FLUSH buckets. Since
4670 neither of those are required at the end of a brigade, this was
4671 really signifying FLUSH_THE_DATA, but that can be determined better
4672 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
4673 buckets now return a length of 0, which is actually the amount of data
4674 read, so they make more sense.
4677 *) Allow the core_output_filter to save some data past the end of a
4678 request. If we get an EOS bucket, we only send the data if it
4679 makes sense to send it. This allows us to pipeline request
4680 responses. As a part of this, we also need to allocate mmap
4681 buckets out of the connection pool, not the request pool. This
4682 allows the mmap to outlive the request.
4685 *) Make blocking and non-blocking bucket reads work correctly for
4686 sockets and pipes. These are the only bucket types that should
4687 have non-blocking reads, because the other bucket types should
4688 ALWAYS be able to return something immediately.
4691 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
4692 server, but use Ctrl+Break to initiate a graceful restart
4693 instead of duplicating behavior. [John Sterling]
4695 *) Patch mod_autoindex to set the Last-Modified header based on
4696 the directory's mtime, and add the ETag header. [William Rowe]
4698 *) Merge the 1.3 patch to add support for logging query string in
4699 such a way that "%m %U%q %H" is the same as "%r".
4702 *) Port three log methods from mod_log_config 1.3 to 2.0:
4703 CLF compliant '-' byte count, method and protocol.
4706 *) Add a new LogFormat directive, %c, that will log connection
4707 status at the end of the response as follows:
4708 'X' - connection aborted before the response completed.
4709 '+' - connection may be kept-alive by the server.
4710 '-' - connection will be closed by the server.
4713 *) Expand APR for WinNT to fully accept and return utf-8 encoded
4714 Unicode file names and paths for Win32, and tag the Content-Type
4715 from mod_autoindex to reflect that charset if the the feature
4716 macro APR_HAS_UNICODE_FS is true. [William Rowe]
4718 *) Compute the content length (and add appropriate header field) for
4719 the response when no content length is available and we can't use
4720 chunked encoding. [Jeff Trawick]
4722 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
4723 so that content input filters get dechunked data when using
4724 the default handler. Also removed REQUEST_CHUNKED_PASS.
4727 *) Add mod_ext_filter as an experimental module. This module allows
4728 the administrator to use external programs as filters. Currently,
4729 only filtering of output is supported. [Jeff Trawick]
4731 *) Most Apache functions work on EBCDIC machines again, as protocol
4732 data is now translated (again). [Jeff Trawick]
4734 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
4735 the EBCDIC support. They are noops on ASCII machines, so this
4736 type of translation doesn't have to be surrounded by #ifdef
4737 CHARSET_EBCDIC. [Jeff Trawick]
4739 *) Fix mod_include. tag commands work again, and the server will
4740 send the FAQ again. This also allows mod_include to set aside
4741 buckets that include partial buckets.
4742 [Ryan Bloom and David Reid]
4744 *) Add suexec support back. [Manoj Kasichainula]
4746 *) Lingering close now uses the socket directly instead of using
4747 BUFF. This has been tested, but since all we can tell is that it
4748 doesn't fail, this needs to be really hacked on.
4751 *) Allow filters to modify headers and have those headers be sent to
4752 the client. The idea is that we have an http_header filter that
4753 actually sends the headers to the network. This removes the need
4754 for the BUFF to send headers.
4757 *) Charset translation: mod_charset_lite handles translation of
4758 request bodies. Get rid of the xlate version of ap_md5_digest()
4759 since we don't compute digests of filtered (e.g., translated)
4760 response bodies this way anymore. (Note that we don't do it at
4761 all at the present; somebody needs to write a filter to do so.)
4764 *) Input filters and ap_get_brigade() now have a input mode parameter
4765 (blocking, non-blocking, peek) instead of a length parameter.
4768 *) Update the mime.types file to the registered media types as
4769 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
4772 *) Namespace protect some macros declared in ap_config.h
4775 *) Support HTTP header line folding with input filtering.
4778 *) Mod_include works again. This should still be re-written, but at
4779 least now we can serve an SHTML page again.
4782 *) Begin to remove BUFF from the core. Currently, we keep a pointer
4783 to both the BUFF and the socket in the conn_rec. Functions that
4784 want to use the BUFF can, functions that want to use the socket,
4785 can. They point to the same place.
4788 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
4789 [Tomas "Ögren" <stric@ing.umu.se>]
4791 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
4792 associated pool goes away. (APR pipes on OS/2 were already had this
4793 logic.) This resolvs a fatal file descriptor leak with CGIs.
4796 *) The final line of the config file was not being read if there was
4797 no \n at the end of it. This was caused by apr_fgets returning
4798 APR_EOF even though we had read valid data. This is solved by
4799 making cfg_getline check the buff that was returned from apr_fgets.
4800 If apr_fgets return APR_EOF, but there was data in the buf, then we
4801 return the buf, otherwise we return NULL.
4804 *) Piped logs work again in the 2.0 series.
4807 *) Restore functionality broken by the mod_rewrite security fix:
4808 rewrite map lookup keys and default values are now expanded
4809 so that the lookup can depend on the requested URI etc.
4810 PR #6671 [Tony Finch]
4812 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
4813 security bug in some mass virtual hosting configurations
4814 that can allow a remote attacker to retrieve some files
4815 on the system that should be inaccessible. [Tony Finch]
4817 *) Add a pool bucket type. This bucket is used for data allocated out
4818 of a pool. If the pool is cleaned before the bucket is destroyed, then
4819 the data is converted to a heap bucket, allowing it to survive the
4823 *) Add a flush bucket. This allows modules to signal that the filters
4824 should all flush whatever data they currently have. There is no way
4825 to actually force them to do this, so if a filter ignores this bucket,
4826 that's life, but at least we can try with this.
4829 *) Add an output filter for sub-requests. This filter just strips the
4830 EOS bucket so that we don't confuse the main request's core output
4831 filter by sending multiple EOS buckets. This change also makes sub
4832 requests start to send EOS buckets when they are finished.
4835 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
4836 makes ap_bucket_destroy a return void, which is okay because it
4837 used to always return APR_SUCCESS, and nobody ever checked its
4838 return value anyway.
4839 [Cliff Woolley <cliffwoolley@yahoo.com>]
4841 *) Remove the index into the bucket-type table from the buckets
4842 structure. This has now been replaced with a pointer to the
4843 bucket_type. Also add some macros to test the bucket-type.
4846 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
4847 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
4848 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
4849 All _VAR_ flavors changes to _DATA to be absolutely clear.
4852 *) Add support for /, //, //servername and //server/sharename
4853 parsing of <Directory> blocks under Win32 and OS2.
4854 [Tim Costello, William Rowe, Brian Harvard]
4856 *) Remove the function pointers from the ap_bucket type. They have been
4857 replaced with a global table. Modules are allowed to register bucket
4858 types and use then use those buckets.
4861 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
4862 once we finish writing the request body to the cgi child process;
4863 otherwise, the client doesn't hit EOF on stdin. Small request bodies
4864 worked without this change (for reasons I don't understand), but large
4865 ones didn't. [Jeff Trawick]
4867 *) Remove file bucket specific information from the ap_bucket type.
4868 This has been moved to a file_bucket specific type that hangs off
4869 the data pointer in the ap_bucket type.
4872 *) Input filtering now has a third argument. This is the amount of data
4873 to read from lower filters. This argument can be -1, 0, or a positive
4874 number. -1 means give me all the data you have, I'll deal with it and
4875 let you know if I need more. 0 means give me one line and one line
4876 only. A positive number means I want no more than this much data.
4878 Currently, only 0 and a positive number are implemented. This allows
4879 us to remove the remaining field from the conn_rec structure, which
4883 *) Big cleanup of the input filtering. The goal is that http_filter
4884 understands two conditions, headers and body. It knows where it is
4885 based on c->remaining. If c->remaining is 0, then we are in headers,
4886 and http_filter returns a line at a time. If it is not 0, then we are
4887 in body, and http_filter returns raw data, but only up to c->remaining
4888 bytes. It can return less, but never more.
4889 [Greg Ames, Ryan Bloom, Jeff Trawick]
4891 *) mod_cgi: Write all of the request body to the child, not just what
4892 the kernel would accept on the first write. [Jeff Trawick]
4894 *) Back out the change that moved the brigade from the core_output_filters
4895 ctx to the conn_rec. Since all requests over a given connection
4896 go through the same core_output_filter, the ctx pointer has the
4900 *) Fix another bug in the send_the_file() read/write loop. A partial
4901 send by apr_send would cause unsent data in the read buffer to
4902 get clobbered. Complete making send_the_file handle partial
4903 writes to the network.
4906 *) Fix a couple of type fixes to allow compilation on AIX again
4907 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
4909 *) Fix bug in send_the_file() which causes offset to be ignored
4910 if there are no headers to send.
4913 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
4914 filter. Useful for supporting Windows 9* with a binary
4915 compiled on Windows NT.
4918 Changes with Apache 2.0a7
4920 *) Reimplement core_output_filter to buffer/save bucket brigades
4921 across multiple calls to the core_filter. The brigade will be
4922 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
4923 thresholds are hit or the EOS bucket is received.
4926 *) Create experimental filter (buffer_filter) that coalesces bytes
4927 into one large buffer before invoking the next filter in the
4928 chain. This filter is particularly useful with the current
4929 implementation of mod_autoindex when it inserted above the
4930 chunk_filter. mod_autoindex generates a lot of brigades that
4931 containing buckets holding just a few bytes each. The
4932 buffer_filter coalesces these buckets into a single large bucket.
4935 *) Add apr_sendfile() support into the core_output_filter.
4938 *) Add apr_sendv() support into the core_output_filter.
4941 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
4942 [Mike Abbott <mja@sgi.com>]
4944 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
4945 make much sense, because Apache uses buckets instead of BUFFs now.
4948 *) send_the_file now falls back to a read/write loop on platforms that
4949 do not have sendfile.
4950 [Ryan Bloom and Brian Havard]
4952 *) Install apachectl correctly, and substitute the proper values so
4953 that it works again. [Ryan Bloom]
4955 *) Better(??) handle platforms that lack sendfile().
4958 *) APR now has UUID generation/formatting/parsing support.
4961 *) Begin the http_filter. This is an input filter that understands
4962 the absolute basic amount required to parse an HTTP Request. The
4963 goal is to be able to split headers from request body before passing
4964 the data back to the other filters.
4967 *) Bring forward from 1.3.13 the config directory implementation
4970 *) install apxs if it is created
4973 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
4974 conversions. [William Rowe]
4976 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
4977 ap_add_output_filter(). [Jeff Trawick]
4979 *) Multiple build and configuration fixes
4982 -add datadir and localstatedir substitutions
4984 -fix logfilename misspelling
4985 -fix evaluation of installation dir variables and
4986 -replace $foobar by $(foobar) to be usefull in the makefile
4990 -add rules for cross-compiling in rules.mk. Okay, rule to check for
4991 $CC_FOR_BUILD is still missing
4992 -use CHECK_TOOL instead of CHECK_PROG for ranlib
4993 -add missing "AR=@AR@" to severaly Makefile.in's
4994 -cache result for "struct rlimit"
4995 -compile all helper programs with native and cross compiler
4996 and use the native version to generate header file
4997 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
4999 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
5001 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
5003 *) Fix a bug where a client which only sends \n to delimit header
5004 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
5005 message. Start working on ebcdic co-existance with input
5007 [William Rowe, Greg Ames]
5009 *) If mod_so is enabled in the server always create libexec, even
5010 if there are no modules installed in this directory. This is a
5011 requirement for APXS to work correctly.
5014 *) Connection oriented output filters are now stored in the
5015 conn_rec instead of the request_rec. This allows us to add the
5016 output filter in the pre-connection phase instead of the
5017 post_read_request phase, which keeps us from trying to write an
5018 error page before we have a filter to write to the network.
5019 [Ryan Bloom, Jeff Trawick, and Greg Ames]
5021 *) Cleaning up an mmap bucket no longer deletes the mmap. An
5022 mmap can be used across multiple buckets (default_handler with
5023 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
5024 the mmap itself can't be associated with the bucket.
5027 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
5030 *) Radical surgery to improve mod_isapi support under Win32.
5031 Includes a number of newer ServerSupportFunction calls, support
5032 for ReadClient (in order to retrieve POSTs greater than 48KB),
5033 and general bug fixes to more reliably load ISAPI .dll's and
5034 prevent leaking handle resources. Note: There are still
5035 discrepancies between IIS's and Apache's ServerVariables, and
5036 async calls are still not supported. Additional warnings are
5037 logged to facilitate debugging of unsupported ISAPI calls.
5040 *) Add input filtering to Apache. The basic idea for the input
5041 filters is the same as the ideas for output filters. The biggest
5042 difference is that instead of calling ap_pass_brigade, ap_get_brigade
5043 should be called, and the order of execution for the filter itself is
5044 different. When writing an output filter, a brigade is passed in,
5045 and filters operate directly on that brigade, when done, they call
5046 ap_pass_brigade. Input filters are the exact opposite. Because input
5047 is not a push operation, filters first call ap_get_brigade. When this
5048 function returns, the input filter will be left with a valid brigade.
5049 The input filter should then operate on the brigade, and return.
5052 *) Fix building on BSD/OS using its native make. The build system
5053 falls back to the BSD .include directive on that host platform.
5056 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
5057 SHA1 and plaintext password encodings. Make feature tests a
5058 bit more flexible. [William Rowe]
5060 *) Charset translation: mod_charset_lite handles output content
5061 translation in a filter. mod_charset_lite no longer ignores
5062 subrequests. A bunch of cruft related to BUFF's support for
5063 translating request and response bodies was removed.
5066 *) Move the addition of the CORE filter to the post_read_request
5067 hook in http_core.c. This removes the need to add the filter in
5068 multiple places and allows for an SSL module to be added much
5069 simpler. [Ryan Bloom]
5071 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
5072 Fix a security problem that affects certain configurations of
5073 mod_rewrite. If the result of a RewriteRule is a filename that
5074 contains expansion specifiers, especially regexp backreferences
5075 $0..$9 and %0..%9, then it may be possible for an attacker to
5076 access any file on the web server. [Tony Finch]
5078 *) Fix a bug where errors that are detected during early request parsing
5079 don't produce visible HTTP error messages at the browser, because
5080 the core_filter wasn't present. [Greg Ames]
5082 *) Provide apr_socklen_t as a portability aid.
5083 [Victor J. Orlikowski]
5085 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
5086 as well as a comment arg to the add, adduser and update cmds.
5087 update allows the user to clear or preserve pw/groups/comment.
5088 Fixed a bug in dbmmanage that prevented the check option from
5089 parsing a password followed by :group... text. Corrected the
5090 seed calcualation for Win32 systems, and added -lsdbm support.
5093 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
5096 *) Avoid a segfault when parsing .htaccess files. An
5097 uninitialized tree pointer was passed to ap_build_config().
5100 *) Change the way that inet_addr & inet_network are checked for
5101 in APR's configure process to allow BeOS BONE to correctly
5102 find them. With this change BeOS BONE now builds from source
5103 with no problems. [David Reid]
5105 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
5106 the end of the parameters to execve() was stored in the wrong
5107 location, overlaying the storage beyond the newargs[] array and
5108 also passing uninitialized storage to execve(), which would
5109 sometimes fail with EFAULT. [Jeff Trawick]
5111 *) Fix a bug parsing configuration file containers. With a sequence
5112 like this in the config file
5114 <IfModule mod_kilroy.c>
5117 <IfModule mod_lovejoy.c>
5122 the second container would be terminated at the blank line due to
5123 sediment in the buffer from reading the prior </IfModule> and an
5124 error message would be generated for the real </IfModule> for the
5125 second container. Also due to this problem, any two characters
5126 could be used for "</" in the close of a container.
5129 *) ap_add_filter prototype changed to remove the ctx pointer. The
5130 pointer still remains in the filter structure, but it can not be
5131 a part of the ap_add_filter prototype. The reason is that when
5132 the core uses AddFilter to add a filter to the stack it doesn't
5133 know how to allocate the ctx pointer, or even how much memory should
5134 be allocated. The filters will have to be responsible for allocating
5135 the ctx memory when they need it.
5138 *) Add an AddFilter directive. This directive takes a list of filters
5139 that should be activated for the requested resource.
5142 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
5143 some other platforms). [Jeff Trawick]
5145 *) Modify mod_include to be a filter. Currently, it has only been tested
5146 on actual files, but it should work for CGI scripts too.
5149 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
5150 writes. apr_flush() for Unix: handle interrupted writes.
5153 *) NameVirtualHost can now take "*" as an argument instead of
5154 an IP address. This allows you to create a purely name-based
5155 virtual hosting server that does not have any IP addresses in
5156 the configuration file and which ignores the local address
5157 of any connections. PR #5595, PR #4455 [Tony Finch]
5159 *) Fix some compile warnings in mod_mmap_static.c
5160 [Mike Abbott <mja@sgi.com>]
5162 *) Fix chunking problem with CGI scripts. The general problem was that
5163 the CGI modules were adding an EOS bucket and then the core added an
5164 EOS bucket. The chunking filter finalizes the chunked response when it
5165 encounters an EOS bucket. Because two EOS buckets were sent, we
5166 finalized the response twice. The fix is to make sure we only send one
5167 EOS, by utilizing a flag in the request_rec.
5170 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
5171 and Win32. Previously, the first read from an apr_file_t set up via
5172 apr_put_os_file() would return a '\0'. [Jeff Trawick]
5174 *) Mod_cgid now creates a single element bucket brigade, with a pipe
5175 bucket, instead of using BUFF's and ap_r*.
5178 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
5179 [Mike Abbott <mja@sgi.com>]
5181 *) Remove ap_bopenf from buff code. This required modifying the file_cache
5182 code to use APR file's directly instead of going through BUFFs.
5185 *) Fix compile break on some platforms for mod_mime_magic.c
5186 [John K. Sterling <sterling@covalent.net>]
5188 *) Fix merging of AddDefaultCharset directive.
5189 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
5191 *) Minor revamp of the rlimit sections of code. We now test
5192 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
5193 is now "available" even if the platform doesn't support
5194 the rlimit family (it's just a noop though). [Jim Jagielski]
5196 *) Migrate the pre-selection of which MPM to use for specific
5197 platforms to hints.m4, which contains (or should contain)
5198 all platform specific "hints". [Jim Jagielski]
5200 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
5203 *) Add tables with non-string/binary values to APR.
5206 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
5209 *) Update PCRE to version 3.2. [Ryan Bloom]
5211 *) Change the way buckets' destroy functions are called so that
5212 they can be more directly used when changing the type of a
5213 bucket in place. [Tony Finch]
5215 *) Add generic support for reference-counting the resources used by
5216 buckets, and alter the HEAP and MMAP buckets to use it. Change
5217 the way buckets are initialised to support changing the type of
5218 buckets in place, and use it when setting aside TRANSIENT buckets.
5219 Change the implementation of TRANSIENT buckets so that it can be
5220 mostly shared with IMMORTAL buckets, which are now implemented.
5223 Changes with Apache 2.0a6
5225 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
5227 *) Add a chunking filter to Apache. This brings us one step closer
5228 to removing BUFF. [Ryan Bloom]
5230 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
5231 added to the stack is the last filter to be called. [Ryan Bloom]
5233 *) Apache 2.0 has been completely documented using Scandoc. The
5234 docs can be generated by running 'make docs'. [Ryan Bloom]
5236 *) Add filtered I/O to Apache. This is based on bucket brigades,
5237 Currently the buckets still use BUFF under the covers, but that
5238 should change quickly. The only currently written filter is the
5239 core filter which just calls ap_bwrite. [The Apache Group]
5241 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
5242 built with thread support. [Jeff Trawick]
5244 *) Abort configuration if --with-layout was specified and there's
5245 no layout definition file. [Ken Coar]
5247 *) Add support for '--with-port=n' option to configure. [Ken Coar]
5249 *) Add support for extension methods for the Allow response header
5250 field, and an API routine for accessing r->allowed and the
5251 list of extension methods in a unified manner. [Ken Coar]
5253 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5254 [Rob Simonson <simo@us.ibm.com>]
5256 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5257 APACHE_XLATE builds. [Jeff Trawick]
5259 *) A configuration file parsing problem was fixed. When the
5260 configuration file started with an IfModule/IfDefine container,
5261 only the last statement in the container would be retained.
5264 Changes with Apache 2.0a5
5266 *) Perchild is serving pages after passing them to different child
5267 processes. There are still a lot of bugs, but this does work. I
5268 have made requests against the same installation of Apache, and had
5269 different servers use different user IDs to serve the responses.
5270 This change moves to using socketpair instead of an AF_UNIX socket.
5273 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5274 It can't seem to pass between child processes yet, but I think we
5275 are closer now than before. This moves us back to using Unix
5276 Domain Sockets. [Ryan Bloom]
5278 *) libapr functions and types renamed with apr_ prefix.
5279 #include "apr_compat.h" for 1.3.x backwards compat
5282 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5283 return the right information on the local socket address.
5284 [Gregory Nicholls <gnicholls@level8.com>]
5286 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5287 [Gregory Nicholls <gnicholls@level8.com>]
5289 *) Add an option to not detach from the controlling terminal without
5290 going into single process mode. This allows for much easier
5291 debugging of the process startup code. [Ryan Bloom]
5293 *) ab: don't use perror() to report the failure of an APR function.
5296 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5297 scoreboard on graceful restarts.
5300 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5301 An invalid ap_proc_t was passed to ap_create_process().
5304 *) Allow modules to register filters. Those filters are still
5305 never called, but this is a step in the right direction.
5306 [Ryan Bloom and Greg Stein]
5308 *) Register the mod_cgid daemon process for cleanup so that it is
5309 killed at termination if it does not die when the parent gets
5310 SIGTERM. This change is to fix occasional problems where the
5311 process stays around. Bugs in similar logic in mod_rewrite and
5312 mod_include were also fixed. [Jeff Trawick]
5314 *) Fix a bug in the time handling. Basically, we were imploding a time
5315 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5316 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5317 uses those two fields to adjust the time value. Because of the HTTP
5318 spec, both of those values can be zero'ed out safely. This fixes
5319 the bug correctly. [Ryan Bloom]
5321 *) Fix a couple of place in the Windows code where the wrong error
5322 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
5324 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5326 *) Added the APR_EOL_STR macro for platform dependent differences in
5327 logfiles and other raw text (such as all APR files). Fixes logfiles
5328 not terminated with cr/lf sequences in Win32. [William Rowe]
5330 *) Move all strings functions in APR to src/lib/apr/strings and create
5331 apr_strings.h for the prototypes. [Ryan Bloom]
5333 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5334 to repeat the syscall until we stop getting EINTR. I noticed a
5335 related problem at termination (SIGTERM) on FreeBSD when using
5336 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5337 implementation work properly with child init. Previously, ap_lock()
5338 was essentially a no-op because all children were using different
5339 locks and thus nobody ever blocked. [Jeff Trawick]
5341 *) The htdocs/ tree has been moved out of the CVS source tree into
5342 a separate area for easier development. This has NO EFFECT on
5343 end-users or Apache installations. [Ken Coar]
5345 *) Integrate the mod_dav module for WebDAV protocol handling. This
5346 adds the dav and dav_fs modules, the SDBM library, and additional
5347 XML handling utilities. [Greg Stein]
5349 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
5352 *) Update the lib/expat-lite/ library (bring forward changes from
5353 the Apache 1.3 repository). [Greg Stein]
5355 *) If sizeof(long long) == sizeof(long), then prefer long in APR
5356 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
5358 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
5359 machines where sendfile is detected, but nobody has written ap_sendfile.
5360 [Dave Hill <ddhill@zk3.dec.com>]
5362 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
5364 *) ab would start up more connections than needed, then quit when the
5365 desired number were finished. Also fixed a logic error involving
5366 ab keepalives. [Victor J. Orlikowski]
5368 *) WinNT: Implement non-blocking pipes with timeouts to communicate
5369 with CGIs. Apache 2.0a4 had non-blocking pipes but without
5370 timeouts (i.e, if a timeout was specified, the pipe reverted to
5371 a full blocking pipe). Now the behaviour is more in line with
5372 Unix non-blocking pipes.
5375 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
5376 cache open file handles along with accept socket reuse enables
5377 Apache 2.0 to serve non-keepalive requests for static files at
5378 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
5379 and Apache 2.0 will serve almost 1200 rps on my system).
5382 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
5383 supports two config directives, mmapfile (same behavious as
5384 mod_mmap_static) and cachefile. Use the cachefile directive
5385 to cache open file handles. This directive only works on systems
5386 that have implemented the ap_sendfile API. cachefile works today
5387 on Windows NT, but has not been tested on any flavors of Unix.
5390 *) Cleanup the configuration. With the last few changes the
5391 configuration process automatically:
5392 inherits information about how to build from APR. Allowing
5393 APR to inform Apache that it should or should not use -ldl
5395 Detects which mod_cgi should be used mod_cgi or mod_cgid,
5396 based on the threading model
5398 Apache calls APR's configure process before finishing it's
5399 configuration processing, allowing for more information flow
5404 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
5405 with non-zero argument makes the socket non-blocking. BeOS and
5406 OS/2 already worked this way. [Jeff Trawick]
5408 *) ap_close() now calls ap_flush() for buffered files, so write
5409 operations work a whole lot better on buffered files.
5412 *) Fix error messages issued from MPMs which explain where to change
5413 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
5416 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
5417 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
5418 now the way that the blocking state of a pipe is manipulated.
5419 ap_block_pipe() is gone. [Jeff Trawick]
5421 *) Correct the problem where the only local host name that the IP stack
5422 can discover are 'undotted' private names. If no fully qualified
5423 domain name can be identified, the default ServerName will be set to
5424 the machine's IP address string. A warning is always provided if the
5425 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
5427 *) Repair problems with config file processing which caused segfault
5428 at init when virtual hosts were defined and which caused ServerName to
5429 be ignored when there was no valid DNS setup. [Jeff Trawick]
5431 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
5433 *) Add ap_sendfile implementation for AIX
5434 [Victor J. Orlikowski]
5436 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
5437 apr_network_io.h, and apr_thread_proc.h.
5438 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
5440 *) Bring the allocation and pool debugging code back into a working
5441 state. This will need to be tested as so far it's only been used on
5444 *) Change configuration command setup to be properly typesafe when in
5445 maintainer mode. Note that this requires a compiler that can initialise
5446 unions. [Ben Laurie]
5448 *) Turn on buffering for config file reads. Part of this was to
5449 repair buffered I/O support in Unix and implement buffered
5450 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
5452 *) Win32: Fix problem where UTC offset was not being set correctly
5453 in the access log. Problem reported on news group by Jerry Baker.
5456 *) Fix segfault when reporting this type of syntax error:
5457 "</container> without matching <container> section", where
5458 container is VirtualHost or Directory or whatever.
5461 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
5462 Prevent the source code for CGIs from being revealed when
5463 using mod_vhost_alias and the CGI directory is under the document root
5464 and a user makes a request like http://www.example.com//cgi-bin/cgi
5465 as reported in <news:960999105.344321@ernani.logica.co.uk>
5468 *) Add support for the new Beos NetwOrking Environment (BONE)
5471 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
5472 final input char is incomplete; ap_bwrite_xlate() now handles
5473 incomplete final input chars. [Jeff Trawick]
5475 *) Yet another update to saferead/halfduplex stuff -- need to ensure
5476 that a bhalfduplex call occurs before logging or else DNS and
5477 such can delay the last packet of the response. [Dean Gaudet]
5479 *) Some syscall reduction in APR on unix -- don't seek when setting
5480 up an mmap; and don't fcntl() more than once per socket.
5483 *) When mod_cgid is started as root, the cgi daemon now switches
5484 to the configured User/Group (like other httpd processes)
5485 instead of continuing as root. [Jeff Trawick]
5487 *) The prefork MPM now uses an APR lock for the accept() mutex.
5488 It has not been getting a lock at all recently. httpd -V now
5489 displays APR's selection of the lock mechanism instead of the
5490 symbols previously respected by prefork. [Jeff Trawick]
5492 *) Change the mmap() feature test to check only for existence.
5493 The previous check required features not used by Apache.
5496 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
5497 sometimes mangled. The len parm to accept() was not
5498 initialized, leading sometimes to an endless loop of failed
5499 accept() calls on OS/390 and anywhere else that failed the call
5500 if the len was negative. Use <sys/un.h> for struct sockaddr_un
5501 instead of declaring it ourselves to fix a compilation problem
5502 on Solaris. [Jeff Trawick]
5504 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
5506 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
5508 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
5510 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
5511 initialization if ALLOC_DEBUG is defined; no known symptom
5512 otherwise. [Jeff Trawick]
5514 *) Fix typo in configure script when checking for mod_so. bash
5515 doesn't seem to have a problem but /bin/sh on Solaris does.
5516 Symptom: "./configure: test: unknown operator =="
5519 *) Rebind the Win32 NT and 9x services control into the MPM.
5520 All console, WinNT SCM and Win9x pseudo-service control code is
5521 now wrapped within the WinNT MPM.
5524 *) Make a copy of getenv("PATH") before storing for later use. Some
5525 getenv() implementations use the same storage for successive calls.
5526 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
5528 *) Server Tokens work in 2.0 again. This also propogates the change
5529 to allow just the product name in the server string using
5533 Changes with Apache 2.0a4
5535 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
5536 won't need to call it. [Greg Ames, Jeff Trawick]
5538 *) Move pre_config hook call to between configuration read and config
5539 tree walk. This allows all modules to implement pre_config hooks
5540 and know that they will be called at an appropriate time.
5543 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
5546 *) Add pre-config hooks back to all modules.
5549 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
5550 ContentDigest enabled and we can't/don't mmap the file.
5553 *) We now report the correct line number for syntax errors in config
5554 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
5556 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
5557 related bugs, and changed shmem/locking to use apr API. Shared-mem
5558 is currently disabled, however, because of problems with graceful
5559 restarts. [Ronald Tschalär]
5561 *) Fix corruption of IFS variable in --with-module= handling.
5562 Depending on the user's shell or customization thereof, there
5563 would be errors generating ap_config_auto.h later in the configure
5564 procedure. [Jeff Trawick]
5566 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
5567 isn't used (as in 1.3), except that on Unix it is now logged via
5568 ap_log_rerror() instead of by the child having STDERR_FILENO refer
5569 to the error log. [Greg Ames, Jeff Trawick]
5571 *) Add '-D' argument processing for run time configuration defines.
5574 *) Organize http_main.c as independent code, such that no code or
5575 global data is exported from it. WIN32 will dynamically link it
5576 to the server core, so this will prevent mutual dependency.
5579 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
5580 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
5583 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
5584 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
5586 *) Add mod_charset_lite for configuring character set translation.
5589 *) Add '-n' option to htpasswd to make it print its user:pw record
5590 on stdout rather than having to frob a text file. [Ken Coar]
5592 *) Fix saferead. Basically, we flush the output buffer if a read on the
5596 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
5597 a conversion is single-byte only. [Jeff Trawick]
5599 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
5600 the BeOS 5.0 documentation says that shutdown doesn't work yet.
5603 *) Fix some minor errors where pid was being manipulated as an int
5604 instead of the portable pid_t. [Roy Fielding]
5606 *) Fix some error log prints that were printing the pointer to a
5607 structure rather than the pid within the structure.
5608 [Jeff Trawick, Roy Fielding]
5610 *) ab: Fix a command-line processing bug; track bad headers in
5611 err_response; support reading headers up to 2K.
5612 [Ask Bjoern Hansen <ask@valueclick.com>]
5614 *) Fix ap_resolve_env() so that it handles new function added in a prior
5615 alpha (see "Added the capability to do ${ENVVAR} constructs in the
5616 config file.") as well as the constructs used by mod_rewrite.
5617 [Paul Reder <rederpj@raleigh.ibm.com>]
5619 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
5621 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
5622 APR to perform translation, instead of accessing the hard-coded tables
5623 in 1.3's ebcdic.c. [Jeff Trawick]
5625 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
5628 *) Add the ability to hook into the config file reading phase. Basically
5629 if a directive is specified EXEC_ON_READ, then when that directive is
5630 read from the config file, the assocaited function is executed. This
5631 should only be used for those directives that must muck with HOW the
5632 server INTERPRETS the config. This should not be used for directives
5633 that re-order or replace items in the config tree. Those changes should
5634 be made in the pre-config step.
5637 *) Add mod_example to the build system.
5640 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
5641 byte character sets. [Jeff Trawick]
5643 *) Pick up various EBCDIC fixes from 1.3 (from Martin
5644 Kraemer and Oliver Reh originally according to the change log).
5647 *) Fix a couple of problems in RFC1413 support (controlled by the
5648 IdentityCheck directive). Apache did not build the request string
5649 properly and more importantly Apache would loop forever if the
5650 would-be ident server dropped the connection before sending a
5651 properly terminated response. [Jeff Trawick]
5653 *) apxs works in 2.0.
5656 *) Reliable piped logs work in 2.0.
5659 *) Introduce a hash table implementation into APR to be used for
5660 replacing tables and other random data structures in Apache.
5663 *) Add some more error reporting to htpasswd in the case of problems
5664 generating or accessing the temporary file. Also, pass in a
5665 buffer if the implementation knows how to use it (i.e., if L_tmpnam
5666 is defined). [Ken Coar]
5668 *) Configure creates config.nice now containing your configure
5669 options. Syntax: ./config.nice [--more-options]
5672 *) Fix various return code problems in APR on Win32. For most of
5673 these, APR was returning APR_EEXIST instead of GetLastError()/
5674 WSAGetLastError(). [Jeff Trawick]
5676 *) Make piped logs work again in version 2.0
5679 *) Add VPATH support to UNIX build system of Apache and APR.
5682 *) Fix ap_tokenize_to_argv to respect the const arguments that are
5686 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
5687 Patch submitted to author.
5690 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
5691 /sbin in PATH on FreeBSD (all submitted to rse previously)
5694 *) Fix building Pthread-based MPMs on OpenBSD
5695 [Sascha Schumann] PR#26
5697 *) Fix ap_readdir() problem on systems where d_name[] field in
5698 struct dirent is declared with only one byte. (This problem only
5699 affected multithreaded builds.) This caused a segfault during
5700 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
5701 least). [Jeff Trawick]
5703 *) Fix some make-portability problems on at least Tru64, Irix
5705 [Sascha Schumann] PR#18, PR#39
5707 *) Add ap_sigwait() to support old-style sigwait() on systems
5708 like OS/390 and UnixWare.
5711 *) Add POSIX-thread flags for more platforms.
5714 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
5715 (on Unix, at least) to handle resolver errors. Fix a bug in
5716 the definition of APR_ENOMEM so that ap_strerror() can spit
5717 out the correct error message for it.
5720 Changes with Apache 2.0a3
5722 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
5725 *) API: *HOOK* macros now have an AP_ prefix
5728 *) Win32: Eliminate redundant calls to initialize winsock.
5729 [Tim Costello <timcostello@ozemail.com.au>]
5731 *) Fix bugs initializing ungetchar for pipes.
5732 [Chia-liang Kao <clkao@CirX.ORG>]
5734 *) The ab program in the src/support directory is now portable using
5738 *) Support directory is being compiled when the server is built
5741 *) The configure option --with-program-name has been added to allow
5742 developers to rename the executable at configure time. This also
5743 changes the name of the config files to match the executable's name.
5746 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
5747 containing version numbers. [Martin Pool]
5749 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
5750 Unix; access_log and error_log now created with these perms; non-
5751 Unix is unaffected [Jeff Trawick]
5753 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
5754 Replaced more magic numbers with MD5_DIGESTSIZE.
5755 [William Rowe, Roy Fielding]
5757 *) Win32: Get mod_auth_digest compiling and added to the Windows
5758 build environment. Not tested and I'd be suprised if it
5759 actually works. [Bill Stoddard]
5761 *) Revamp the Win32 make environment. Makefiles have been removed and
5762 Apache.dsw created to bring together all the pieces. Create new file
5763 os/win32/BaseAddr.ref to define module base addresses (to prevent
5764 dll relocation at start-up).
5765 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
5767 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
5768 of the \015, \012, and \015\012 constants with macros.
5771 *) Add ap_xlate_open() et al for translation of text between different
5772 character sets. The initial implementation requires iconv().
5775 *) More FAQs and answers from comp.infosystems.www.servers.unix.
5776 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5778 *) CGI output is being timed out now.
5781 *) Fix the problem with dieing quietly. dupfile now takes a pool which
5782 is used by the new apr file. There is no reason to create a new file
5783 with the same lifetime as the original file.
5786 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
5787 module base addresses. This will help shooting seg faults
5788 in the field. [William Rowe <wrowe@lnd.com>]
5790 *) Update Apache on Windows documentation. Add new document
5791 describing how to compile Apache on Windows.
5792 [William Rowe <wrowe@lnd.com>]
5794 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
5795 microseconds instead of seconds. Some storage leaks and other
5796 minor bugs in related code were fixed. [Jeff Trawick]
5798 *) Win32: First cut at getting mod_isapi working under 2.0
5799 [William Rowe <wrowe@lnd.com>]
5801 *) First stab at getting mod_auth_digest working under 2.0
5802 quick change summary:
5803 - moved the random byte generation (ap_generate_random_bytes) into APR
5804 - now uses ap_time_t
5805 - compiles and runs on linux
5807 [Brian Martin <bmartin@penguincomputing.com>]
5809 *) Win32: Move the space stripping of physical service names
5810 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
5811 unresolved symbol. Add dependency checking to the
5812 CreateService call to ensure TCPIP and AFP (winsock) is started
5814 [William Rowe <wrowe@lnd.com>]
5816 *) Win32: Add code to perform latebinding on functions that may
5817 not exist on all levels of Windows where Apache runs. This
5818 is needed to allow Apache to start-up on Win95/98. All calls
5819 to non portable functions should be protected with
5820 ap_oslevel checks to prevent runtime segfaults.
5821 [William Rowe <wrowe@lnd.com>]
5823 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
5825 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
5827 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
5828 This addresses PR 1623. Still need to address timing out runaway
5829 CGI scripts. [Bill Stoddard]
5831 *) Win32: Make ap_stat Windows 95/98 friendly
5832 [William Rowe <wrowe@lnd.com>]
5834 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
5835 always fail. Need to initialise the dwOSVersionInfoSize member of the
5836 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
5839 The patch also enhances ap_get_oslevel (and the associated enum) to
5840 handle selected service packs for NT4, and adds recognition for
5841 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
5842 we can use ReadFileScatter and WriteFileGather in readwrite.c.
5843 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
5845 *) Get mod_rewrite building and running, and mod_status building for Win NT
5846 [Allan Edwards <ake@raleigh.ibm.com>]
5848 *) Patch to port mod_auth_db to the 2.0 api and also to support
5849 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
5850 2.7.7. It should work with version 1 as well but I haven't tested it.
5851 [Brian Martin <bmartin@penguincomputing.com>]
5853 *) Get APR DSO code working under Windows. Includes cross platform
5855 [Tim.Costello@BTFinancialgroup.com]
5857 *) Fix some of the Windows APR time functions.
5860 *) FAQ changes related to tidying up historical documents on the web site.
5861 [Joshua Slive <slive@finance.commerce.ubc.ca>]
5863 *) Move Windows DSO code into APR.
5866 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
5867 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
5868 at build time. At this point, the server will not compile on Windows because
5869 of the recent DSO commits. Fixing those next.
5870 [Bill Rowe & Bill Stoddard]
5872 *) Added error checking for file I/O APR routines.
5873 [Jon Travis <jtravis@covalent.net>]
5875 *) APR: Don't use the values of resolver error codes for the
5876 corresponding APR error codes. On Unix and Win32, return the
5877 proper APR error code after a resolver error. [Jeff Trawick]
5879 Changes with Apache 2.0a2
5881 *) Renamed the executable back to httpd on all platforms other
5885 *) Allow BeOS to survive restarts, log properly and a few
5886 small things it had problems with due to the way it setup
5887 users and groups. [David Reid]
5889 *) Get mod_rewrite working with APR locks
5890 [Paul Reder <rederpj@raleigh.ibm.com>]
5892 *) Actually remove the sempahore when the lock cleanup routine
5893 is called on BeOS. [David Reid]
5895 *) Clear hook registrations between reads of the config file.
5896 When DSOs are unloaded and re-loaded the old hook pointers may
5897 no longer be valid. This fix eliminates potential segfaults.
5898 [Allan Edwards <ake@raleigh.ibm.com>]
5900 *) Fix a problem with Sigfunc not being defined or bypassed
5901 if sigaction() wasn't found. [Jim Jagielski]
5903 *) Fix the locking mechanism on BSD variants. They now use fcntl
5904 locks. This allows the server to start and serve pages.
5907 *) First cut at getting the Win32 installer to work
5908 [William Rowe <wrowe@lnd.com>]
5910 *) Get htpasswd compiling under Windows
5911 [William Rowe <wrowe@lnd.com>]
5913 *) Change the log message for a bind() failure to show the
5914 interface and port number. [Jeff Trawick]
5916 *) Import the documentation from 1.3.12 and bring parts of it
5917 up-to-date with respect to the changes that have occurred
5921 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
5922 now logged correctly on BeOS.
5925 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
5926 Makefile.win includes the same user interface as the old
5928 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
5930 *) Win32 exec now uses COMSPEC environment string for command
5931 shell path resolution.
5932 [William Rowe <wrowe@lnd.com>] PR#3715
5934 *) Win32: ap_connect() was not returning correct error condition
5936 [Allen Prescott <allen@clanprescott.com>]
5938 *) Win32: ap_open() was broken on Win9x because an NT-specific
5939 flag was passed to CreateFile. ap_puts() added an unnecessary
5941 [Jeff Trawick <trawick@us.ibm.com>]
5943 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
5944 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
5945 confusing ee/et name and made all extensions language/dialect
5946 rather than country reflecting. Changed example files to
5947 explicit reflect the ISO charset and added a few common
5948 ones to the example config [dirkx]
5950 *) Extend external module capability. To use this, you call
5951 configure with --with-module=path/to/mod1,path/to/mod2,etc.
5954 *) Backported the various "default charset" fixes from 1.3.12,
5955 including the AddDefaultCharset directive. [Jim Jagielski]
5957 *) Added the capability to do ${ENVVAR} constructs in the
5958 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
5959 it does this on a line by line basis; i.e. if the envvar
5960 expands to something with spaces you have to protect it
5961 by adding quotes around it (Unless of course you expect it
5962 to contains more than one argument. Alternatively you
5963 can compile it on a per token basis; which is what people
5964 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
5965 hampers fancier hacks.
5966 [Dirk-Willem van Gulik]
5968 *) Changed the 'ErrorDocument' syntax in that it NO longer
5969 supports the asymetric
5971 ErrorDocument 301 "Some message
5973 Note the opening " quote, without a closing quote. It now
5974 has either the following syntaxes
5976 ErrorDocument XXX /local/uri
5977 ErrorDocument XXX http://valid/url
5978 ErrorDocument XXX "Some Message"
5980 The recognition heuristic is: if it has a space it
5981 is a message. If it has no spaces and starts with a /
5982 or is a valid URL then treat it that way. Otherwise it
5983 is assumed to be a message.
5985 This breaks backward compatibility but makes live a hell
5986 of a lot easier for GUI's and config file parsers.
5987 [Dirk-Willem van Gulik]
5989 *) Changed 'CacheNegotiatedDocs' from its present/not-present
5990 syntax into a 'on' or 'off' syntax. As it currently is the
5991 only non nesting token which uses NO_ARGS and thus is an
5992 absolute pain for any config interface automation. This
5993 breaks backward compatibility. [Dirk-Willem van Gulik]
5995 *) Add ability to add external modules to the build process. This is
5996 done with --with-module=/path/to/module. Modules can only be added
5997 as static modules at this point.
6000 Changes with Apache 2.0a1
6002 *) Fix FreeBSD 3.3 core dump.
6003 Basically, ap_initialize() needs to get called before
6004 create_process(), since create_process() passes op_on structure
6005 to semop() to get a lock, but op_on isn't initialized until
6006 ap_initialize() calls setup_lock(). Here is a slight
6007 rearrangement to main() which calls ap_initialize() earlier...
6008 [Jeff Trawick <trawick@us.ibm.com>]
6010 *) Enable Apache to use sendfile/TransmitFile API
6011 [Bill Stoddard, David Reid, Paul Reder]
6013 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
6017 *) Make file I/O and network I/O writev/sendv APIs consistent.
6018 Eliminate use of ap_iovec_t and use Posix struct iovec.
6019 Use seperate variable on ap_writev to set the number of iovecs
6020 passed in and number of bytes written.
6023 *) Adapt file iol to use APR functions. Replaced ap_open_file()
6024 with ap_create_file_iol(). ap_create_file_iol() requires that
6025 the file be opened prior to the call using ap_open().
6028 *) Port mod_include and mod_cgi to 2.0
6029 [Paul Reder, Bill Stoddard]
6031 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
6032 bytes_read/bytes_written is always valid (never -1). Plus
6033 some fixes to buff.c to correct problems introduced by the
6034 errno => ap_status_t changes a while back. Plus a fix to
6035 chunked encoding introduced right at the beginning of 2.0.
6038 *) Revamped UNIX build system to use autoconf and libtool.
6039 [Manoj Kasichainula, Sascha Schumann]
6041 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
6043 *) SECURITY: More rigorous checking of Host: headers to fix security
6044 problems with mass name-based virtual hosting (whether using mod_rewrite
6045 or mod_vhost_alias).
6046 [Ben Hyde, Tony Finch]
6048 *) Add back support for UseCanonicalName in <Directory> containers.
6049 [Manoj Kasichainula]
6051 *) Added APLOG_STARTUP log type. This allows us to write an error
6052 message without any of the date and time information. As a part
6053 of this change, I also removed all of the calls to fprintf(stderr
6054 and replaced them with calls to ap_log_error using APLOG_STARTUP
6055 writing to stderr is no longer portable, because we don't direct
6056 stderr to the error log on all platforms.
6059 *) Convert error logging functions to take errno as an argument.
6060 This makes our error logs more portable, because some Windows API's
6061 don't set errno. This change allows us to still output a valid
6062 message on all of our platforms.
6065 *) mod_mime_magic runs in 2.0-dev now.
6066 [Paul Reder <rederpj@raleigh.ibm.com>]
6068 *) sendfile has been added to APR.
6069 [John Zedlewski <zedlwski@Princeton.EDU>]
6071 *) buff.c has been converted to no longer use errno.
6072 [Manoj Kasichainula]
6074 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
6075 interface adaption to APR functions did it. [Martin Kraemer]
6077 *) Support DSOs properly on 32-bit HP-UX 11.0
6078 [Dilip Khandekar <dilip@cup.hp.com>]
6080 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
6081 [Ralf S. Engelschall]
6083 *) Cleaned APR build environment integration and bootstrap APR
6084 automatically for developers from src/Configure.
6085 [Ralf S. Engelschall]
6087 *) Fixed building of src/support/htpasswd.c
6088 [Ralf S. Engelschall]
6090 *) When generating the Location: header, mod_speling forgot
6091 to escape the spelling-fixed uri. (Forw-Port from 1.3)
6094 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
6096 *) Change all pools to APR contexts. This is the first step to
6097 incorporating APR into Apache. [Ryan Bloom]
6099 *) Move "handler not found" warning message to below the check
6100 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
6101 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
6103 *) Support line-continuation feature in config.option file and
6104 allow the loading of multiple option sections at once via
6105 ``--with-option=<section1>,<section2>,...''
6106 [Ralf S. Engelschall]
6108 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
6110 Changes with Apache MPM
6112 *) Use asynchronous AcceptEx() and a completion port to accept and
6113 dispatch connections to threads in Windows NT/2000.
6116 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
6119 *) Implement the APACI --with-option facility
6120 (per default used the config.option file).
6121 [Ralf S. Engelschall]
6123 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
6125 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
6126 Replace pre_connection module call with a register_hook call and
6127 implement pre_connection as a hook. The intent is that these hooks will
6128 be extended to allow Apache to be multi-protocol, and also to allow the
6129 calling order to be specified on a per-hook/per-module basis.
6132 *) Implement mpm_* methods as "modules". Each method gets its own
6133 subdir in src/modules (eg: src/modules/prefork). Selection
6134 of method uses Rule MPM_METHOD. [Jim Jagielski]
6136 *) Port the hybrid server from the apache-apr repository as
6137 mpm_mpmt_pthread. [Manoj Kasichainula]
6139 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
6140 amongst the unix MPMs.
6142 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
6143 signal handling for the new world order. [Dean Gaudet]
6145 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
6146 of alloc.c for now. [Dean Gaudet]
6148 *) Handle partial large writes correctly. [Ben Laurie]
6150 *) Eliminate conn_rec's pointer to server. All it knows is the base server
6151 based on IP/port. [Ben Laurie]
6153 *) Port a bunch of modules to the new module structure.
6154 ["Michael H. Voase" <mvoase@midcoast.com.au>]
6156 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
6158 *) Basic restructuring to introduce the MPM concept; includes various
6159 changes to the module API... better described by
6160 docs/initial_blurb.txt. [Dean Gaudet]
6162 Changes with Apache pthreads
6164 *) New buff option added: BO_TIMEOUT. It describes the timeout for
6165 buff operations (generally over a network).
6166 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
6168 *) Created http_accept abstraction. Added 4 new functions (not exported):
6169 init_accept(), begin_accepting_requests(), get_request(),
6170 stop_accepting_requests() [Bill Stoddard]
6172 *) Fix to ap_rprintf call that allows mod_info to work properly.
6173 [James Morris <jmorris@intercode.com.au>]
6175 *) user and ap_auth_type fields were moved from connection_rec to
6176 request_rec. [Ryan Bloom]
6178 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
6179 needed in a threaded server.
6181 *) Initial pthread implementation from from Dean's apache-nspr code.
6182 [Bill Stoddard, Ryan Bloom]
6185 Changes with Apache 1.3.9
6187 *) Remove bogus error message when a redirect doesn't set Location.
6188 Instead, use an empty string to avoid coredump if the error message
6189 was supposed to include a location. [Roy Fielding]
6191 *) Don't allow configure to include mod_auth_digest unless it is
6192 explicitly requested, even if the user asked for all modules.
6195 *) Translate module names to dll names for OS/2 so that they are no more
6196 than 8 characters long and have an extension of "dll" instead of "so".
6199 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
6200 Fix test-compile check to check for randbyte instead of trand32.
6201 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
6202 and tweak to make Amaya happier. [Ronald Tschalär]
6204 *) Ensure that the installed expat include files are world readable,
6205 just like the other header files. [Martin Kraemer]
6207 *) Fixed generated AddModule adjustments in APACI's `configure' script
6208 in order to allow (new) modules like mod_vhost_alias to be handled
6209 correctly (which was touched by the adjustments for mod_alias).
6210 [Ralf S. Engelschall]
6212 *) For binary builds, add -R flag to apachectl to work around the lack of
6213 an absolute path to the ./libexec directory where the libhttp.ep file
6214 is needed for SHARED_CORE architectures. [Randy Terbush]
6216 *) WIN32: Create the CGI script process as DETACHED. This may solve the
6217 problem observed by some Win95/98 users where they get CGI script
6218 output sent to the console. [Bill Stoddard]
6220 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
6221 routines are now called ap_base64* and are 'plain' (i.e., no
6222 pool access or anything clever). Inside util.c the routines acting
6223 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
6224 The oddly named ap_uuencode(), ap_uudecode() are kept around for
6225 now but deprecated. [dirkx]
6227 *) Clean up the base64 and SHA1 additions and make sure they are
6228 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
6229 files. [Roy Fielding]
6231 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
6232 checking. Allow compiling on VS 6.0. [Randy Terbush]
6234 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
6236 *) Use TestCompile to search for the truerand library (rather than blindly
6237 assuming its existence). If it is not found, complain (but do not
6238 exit - yet). [Martin Kraemer]
6240 *) We forgot to add the new exported function names to
6241 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
6243 *) Add description of -T command-line option to usage().
6244 [Ralf S. Engelschall]
6246 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
6247 searched only AFTER libap has been searched, because libap needs
6248 some symbols from libos. [Martin Kraemer]
6250 *) Fix conflict with original mod_digest related to the symbol of the
6251 module dispatch list (which has to be unique for DSO and follow the
6252 usual conventions for the installation procedure).
6253 [Ralf S. Engelschall]
6255 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6256 for other platforms as well. [Martin Kraemer]
6258 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6259 types by AP_LONG and replace reference to renamed variable 'ubuf'
6260 by 'buffer'. [Martin Kraemer]
6262 Changes with Apache 1.3.8 [not released]
6264 *) Flush the output buffer immediately after sending an error or redirect
6265 response, since the result may be needed by the client to abort a
6266 long data transfer or restart a series of pipelined requests.
6267 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
6269 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6270 [Ian Turner <iant@sequent.com>] PR#4735
6272 *) Local struct mmap in http_core.c conflicted with system structure
6273 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6275 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6276 [Ronald Tschalär <ronald@innovation.ch>]
6278 *) Fix a memory leak where the module counts were getting messed
6279 up across restarts. [David Harris <dharris@drh.net>]
6281 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6282 properly in mod_access.
6283 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
6285 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6286 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
6288 *) PORT: Support for compaq/tandem/com.
6289 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
6291 *) Added SHA1 password encryption support to easy migration from
6292 Netscape servers. See support/SHA1 for more information.
6293 Caused the separation of ap_md5.c into md5, sha1 and a general
6294 ap_checkpass.c with just a validate_passwd routine. Added a
6295 couple of flags to support/htpasswd. Some reuse of the to64()
6296 function; hence renamed to ap_to64().
6297 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
6299 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6300 with ASCII/EBCDIC conversions in "ident" query.
6301 [David McCreedy <McCreedy@us.ibm.com>]
6303 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6304 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6305 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6307 *) Fix SIGSEGV on some systems because the Vary fix below included
6308 a call to table_do with a variable argument list that was not
6309 NULL terminated. Replaced with better implementation. [Roy Fielding]
6311 Changes with Apache 1.3.7 [not released]
6313 *) The "Vary" response header field is now sanitised right before
6314 the header is sent back to the client. Multiple "Vary" fields
6315 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6316 "Vary: host, negotiate, host, accept-language") are reduced to
6317 single instances. This is a better solution than the force-no-vary
6318 one (which is still valid for clients that can't cope with Vary
6319 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6321 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
6323 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6324 least on Linux and FreeBSD for now.
6327 *) Win32: More apache -k restart work. Restarts are now honored
6328 immediately and connections in the listen queue are -not- lost.
6329 This is made possible by the use of the WSADuplicateSocket()
6330 call. The listeners are opened in the parent, duplicated, then
6331 the duplicates are passed to the child. The original listen sockets
6332 are not closed by the parent across a restart, thus the listen queue
6334 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6336 *) Fix handling of case when a client has sent "Expect: 100-continue"
6337 and we are going to respond with an error, but get stuck waiting to
6338 discard the body in the pointless hope of preserving the connection.
6339 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
6341 *) Fix 'configure' to work correctly with SysV-based versions of
6342 'tr' (consistent with Configure's use as well). [Jim Jagielski]
6344 *) apxs: Add "-S var=val" option which allows for override of CFG_*
6345 built-in values. Add "-e" option which works like -i but doesn't
6346 install the DSO; useful for editing httpd.conf with apxs. Fix
6347 editing code so that multiple invocations of apxs -a will not
6348 create duplicate LoadModule/AddModule entries; apxs can now be
6349 used to re- enable/disable a module. [Wilfredo Sanchez]
6351 *) Win32: Update the server to use Winsock 2. Specifically, link with
6352 ws2_32.lib rather than wsock32.lib. This gives us access to
6353 WSADuplcateSocket() in addition to some other enhanced comm APIs.
6354 Win 95 users may need to update their TCP/IP stack to pick up
6355 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
6356 [Bill Stoddard stoddard@raleigh.ibm.com]
6358 *) Win32: Redirect CGI script stderr (script debug info) into the
6359 error.log when CGI scripts fail. This makes Apache on Win32
6360 behave more like Unix.
6361 [Bill Stoddard stoddard@raleigh.ibm.com]
6363 *) Fixed `httpd' usage display: -D was missing.
6364 [Ralf S. Engelschall] PR#4614
6366 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
6367 [Ralf S. Engelschall] PR#4561, PR#4562
6369 *) OS/2: Fix problem with accept lock semaphores where server would die with
6370 "OS2SEM: Error 105 getting accept lock. Exiting!"
6371 [Brian Havard] PR#4505
6373 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
6374 [Randy Terbush <randy@covalent.net>]
6376 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
6377 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
6379 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
6380 command potentially _is_ GCC. [Ralf S. Engelschall]
6382 *) Fix apxs build issues on AIX
6383 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
6385 *) DocumentRoot Checking: Under previous versions, when Apache
6386 first started up, it used to do a stat of each DocumentRoot to
6387 see if it existed and was a directory. If not, then an error
6388 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
6389 does not exist, you will get error messages in error_log. If
6390 the '-t' command line option is used (to check the configuration)
6391 the check of DocumentRoot IS performed. An additional command
6392 line option, '-T', has been added if you want to avoid the
6393 DocumentRoot check even when checking the configuration.
6396 *) Win32: The query switch "apache -S" didn't exit after showing the
6397 vhost settings. That was inconsistent with the other query functions.
6398 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
6400 *) Win32: Changed behaviour of apache -k restart.
6401 Previously, the server would drain all connections in the stack's
6402 listen queue before honoring the restart. On a busy server, this
6403 could take hours. Now, a restart is honored almost immediately.
6404 All connections in Apache's queues are handled but connections in
6405 the stack's listen queue are discarded. Restart triggered by
6406 MaxRequestPerChild is unchanged.
6407 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6409 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
6410 the accept loop. Good for a 5% performance boost. Cleaned up
6411 parent/child process management code.
6412 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6414 *) Added ceiling on file size for memory mapped files.
6415 [John Giannandrea <jg@meer.net>] PR#4122
6417 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
6418 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
6419 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
6421 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
6422 use this at least for Expat. [Ralf S. Engelschall]
6424 *) Allow .module files to specify libraries with Lib:.
6427 *) Allow SetEnvIf[NoCase] to test environment variables as well
6428 as header fields and request attributes. [Ken Coar]
6430 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
6431 content-types are "text/html;parameters". PR#4524 [Ken Coar]
6433 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
6434 never accepted into any standard, and it opens up certain DoS
6435 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
6437 *) TestCompile updated. We can now run programs and output the
6438 results during the Configure process. [ Jim Jagielski]
6440 *) The source is now quad (long long) aware as needed. Specifically,
6441 the Configure process determines the correct size of off_t and
6442 *void. When the OS/platform/compiler supports quads, ap_snprintf()
6443 provides for the 'q' format qualifier (if quads are not available,
6444 'q' is silently "demoted" to long). [Jim Jagielski]
6446 *) When the username or password fed to htpasswd is too long, include the
6447 size limit in the error message. Also report illegal characters
6448 (currently only ':') in the username. Add the size restrictions
6449 to the man page. [Ken Coar]
6451 *) Fixed the configure --without-support option so it doesn't result in
6452 an infinite loop. [Marc Slemko]
6454 *) Piped error logs could cause a segfault if an error occured
6455 during configuration after a restart.
6456 [Aidan Cully <aidan@panix.com>] PR#4456
6458 *) If a "Location" field was stored in r->err_headers_out rather
6459 than r->headers_out, redirect processing wouldn't find it and
6460 the server would core dump on ap_escape_html(NULL). Check both
6461 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
6462 if Location isn't set. [Doug MacEachern, Ken Coar]
6464 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
6465 of the Expat 1.0.2 distribution. [Greg Stein]
6467 *) Replace regexec() calls with calls to a new API stub function
6468 ap_regexec(). This solves problems with DSO modules which use the regex
6469 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
6471 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
6472 environment variables can be set according to the protocol version
6473 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
6475 *) Add DSO support for OpenStep (Mach 4.2) platform.
6476 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
6478 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
6479 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
6481 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
6482 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
6484 *) Better DSO flags recognition on NetBSD platforms using ELF.
6485 [Todd Vierling <tv@pobox.com>] PR#4310
6487 *) Always log months in english format for %t in mod_log_config.
6488 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
6490 *) Support for server-parsed and multiview-determined ReadmeName and
6491 HeaderName files in mod_autoindex. Removed the restriction on
6492 "/"s in ReadmeName and HeaderName directives since the *sub_req*
6493 routines will deal with the access issues. (It's now possible to
6494 have {site|group|project|customer|...} wide readmes and headers.)
6495 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
6498 *) When stat() fails, don't assume anything about the contents of
6499 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
6501 *) It's OK for a semop to return EINTR, just loop around and try
6502 again. [Dean Gaudet]
6504 *) Fix configuration engine re-entrant hangups, which solve a
6505 handful of problems seen with mod_perl <Perl> configuration sections
6506 [Salvador Ortiz Garcia <sog@msg.com.mx>]
6508 *) Mac OS and Mac OS X Server now use the appropriate custom layout
6509 by default when building with APACI; allow for platform-specific
6510 variable defaults in configure. [Wilfredo Sanchez]
6512 *) Do setgid() before initgroups() in http_main; some platforms
6513 zap the grouplist when setgid() is called. This was fixed in
6514 suexec earlier, but the main httpd code missed the change.
6515 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
6517 *) Add recognition of .tgz as a gzipped tarchive.
6518 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
6520 *) mod_include's fsize/flastmod should allow only relative paths, just
6521 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
6523 *) OS/2: Add support for building loadable modules using DLLs.
6526 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
6529 *) Fix minor but annoying bug with the test for Configuration.tmpl
6530 being newer than Configuration so that it is less likely to fail
6531 when using APACI and shadow sources. [Wilfredo Sanchez]
6533 *) PORT: Add initial support for Mac OS (versions 10.0 and
6534 greater). Use Mac OS X Server layout for now. Clean up dyld code
6535 in unix/os.c, and don't install the dyld error handlers, which
6536 are no longer needed in Mac OS. [Wilfredo Sanchez]
6538 *) Rename Rhapsody layout to "Mac OS X Server". Change install
6539 locations to appropriate ones for user-built (as opposed to
6540 system) installs. [Wilfredo Sanchez]
6542 *) Modify mod_autoindex's handling of AddDescription so that the
6543 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
6545 *) Add functionality to the install-bindist.sh script created by
6546 binbuild.sh to use tar when copying distribution files to the
6547 serverroot. This allows upgrading an existing installation
6548 without nesting the new distribution in the old.
6550 install-bindist.sh now detects the local perl5 path to install
6551 apxs and dbmmanage with proper path to perl interpreter.
6553 Add an install-binsupport target which copies the source files
6554 for apxs and dbmmanage to bindist to allow these scripts to
6555 be properly installed relative to the destination serverroot.
6556 [Randy Terbush, Covalent Technologies, randy@covalent.net]
6558 *) Fix intermittent SEGV in ap_proxy_cache_error() in
6559 src/modules/proxy_util.c where a NULL filepointer and

6567 *) OS/2: Fix terminating CGIs that aren't compiled by EMX GCC when a
6568 connection is aborted. [Brian Havard]
6570 *) Force the LANG envariable to the known state of "C" so that we
6571 have assurance about how string manipulators (e.g., tr) will
6572 function. [Ken Coar] PR#1630
6574 *) Add a directive to allow customising of the tracking cookie name.
6575 [Ken Coar] PR#2921, 4303
6577 *) Add "force-no-vary" envariable to allow servers to work around
6578 clients that choke on "Vary" fields in the response header.
6579 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
6581 *) Fixed a bug in mod_dir that causes a child process will infinitely
6582 recurse when it attemps to handle a request for a directory wnd the
6583 value of the DirectoryIndex directive is a single dot. Also likely
6584 to happen for anyother values of DirectoryIndex that will map back
6585 to the same directory. The handler now only considers regular files
6586 as being index candidates. No PR#s found.

6589 *) Ease configuration debugging by making TestCompile fall back to

6593 [Raymond S Brand <rsbx@rsbx.net>] PR#4248
6595 *) Add "opt" (SysV-style) layout to config.layout. [Raymond S Brand
6598 *) Add APACI --without-execstrip option which can be used to disable the
6599 stripping of executables on installation. This is very important for DSO
6600 and debugging situations. [Ralf S. Engelschall]

6622 *) Fix the ownership delegation for proxy directory under `make install'.

6625 *) APACI would not correctly build suexec. [Maria Verina
6626 <mariav@icgeb.trieste.it>] PR#4260

6668 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
6671 *) Correct an apparent typo: on the Windows and MPE platforms, the
6672 htpasswd utility was limiting passwords to only 8 characters.
6675 *) EBCDIC platforms: David submitted patches for two bugs in the
6676 MD5 digest port for EBCDIC machines:
6677 a) the htdigest utility overwrote the old contents of the digest file
6678 b) the Content-MD5 header value (ContentDigest directive) was wrong
6679 when the returned file was not converted from EBCDIC, but was a
6680 binary (e.g., image file) in the first place.
6681 [David McCreedy <mccreedy@us.ibm.com>]
6683 *) support/htpasswd now permits the password to be specified on the

6685 need to be maintained by scripts -- particularly in the Win32
6686 environment. [Ken Coar]
6688 *) Win32: Win32 multiple services patch. Added capability to install and
6689 run multiple copies of apache as individual services.

6720 in the TPF cross-compilation. [Ken Coar]
6722 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
6723 a roughly 5 fold speed up. [Brian Havard]
6725 *) proxy ftp: instead of using the hardwired string "text/plain" as
6726 a fallback type for files served by the ftp proxy, use the
6727 ap_default_type() function to determine the configured type.
6728 This allows for special configurations like
6729 <Directory proxy:ftp://some.host>
6730 DefaultType gargle/blurb
6732 Additionally, add the Content-Encoding: header to FTP proxy replies
6733 when the encoding is defined (by the AddEncoding directive).
6734 Because it was missing, it was almost impossible to browse compressed
6735 files using the FTP proxy (works now perfectly in Communicator).
6736 The ftp proxy now also returns the Date: and Server: header lines (if not
6737 much else... This code is "somewhat" broken) like normal requests do.
6740 *) Be more smart in APACI's configure script when determining the UID/GID
6741 for User/Group directives and use the determined UID/GID to initialize
6742 the permissions on the proxycachedir.
6743 [Dirk-Willem van Gulik, Ralf S. Engelschall]
6745 *) Changed the forking-prior-to-cleanup in the proxy module to first
6746 check wether it actually needs to collect garbage. This reduces
6747 the number of fork()s from one/request to just the odd one an hour.
6748 [Dirk-Willem van Gulik]
6750 *) Added proxy, auth and header support to src/support/ab.c. Added a
6751 README file to src/support/
6752 [Dirk-Willem van Gulik]
6754 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.
6755 [Ralf S. Engelschall] PR#4050
6757 *) Add support for DSO module compilation on BSD/OS 3.x.
6758 [Randy Terbush, Covalent Technologies]
6760 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
6761 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
6762 option) were substituted with $(TARGET).conf, etc. Same for other strings
6763 with dots where the dot wasn't matched as plain text.
6764 [Ralf S. Engelschall]
6766 *) PORT: Add support for FreeBSD 4.x [Ralf S. Engelschall]
6768 *) Fix verbose output of APACI configure (option -v)
6769 [Martin Kraemer, Ralf S. Engelschall]
6771 Changes with Apache 1.3.6
6773 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
6775 Changes with Apache 1.3.5 [not released]
6777 *) M_INVALID needed a value within the scope of METHODS so that unknown
6778 methods can be access controlled. [Roy Fielding] PR#3821
6780 *) Added PassAllEnv; makes server's entire environment available
6781 to CGIs and SSIs executed within directive's scope. [Ken Coar]
6783 *) ap_uuencode() always added two trailing '='s and encoding of
6784 8 bit characters on a machine with signed char may produced
6785 incorrect results. Additionally ap_uuencode() should now
6786 work correctly on EBCDIC platforms.
6787 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
6789 *) WIN32: Binary installer now runs the configuration DLL before
6790 the reboot prompt (which is only given if MSVCRT.DLL system
6791 DLL is new or updated). This should avoid the configuration
6792 directory being empty after installation. [Paul Sutton]
6793 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
6795 *) WIN32: Binary installer now creates Start menu options to start
6796 and stop Apache as a console application and to uninstall
6797 the Apache service on NT. [Paul Sutton] PR#3741
6799 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
6801 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
6802 have been reported with flock() locking (probably related to kernel
6803 version). [Dean Gaudet] PR#2723, 3531
6805 *) Using APACI, the main config file (usually httpd.conf) was
6806 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
6807 <wsanchez@apple.com>]
6809 *) PORT: AIX does not require the SHARED_CODE "hack"
6810 [Ryan Bloom <rbb@raleigh.ibm.com>]
6812 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
6813 avoidance code added in 1.3.3.
6814 [Dean Gaudet, Jeff Lewis <lewis@stanford.edu>] PR#3872
6816 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
6817 for 8-bit safeness. [Dean Gaudet]
6819 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
6820 because SPARCs have a small machine-specific maximum size for the Global
6821 Offset Table which is often exceeded when compiling one of the larger
6822 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
6824 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
6825 DSO/DLL section because it's a directive from mod_status and isn't
6826 available before the DLL of mod_status is loaded.
6827 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
6829 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
6830 continuation facility in Apache's configuration files which could
6831 lead to a buffer overflow situation.
6832 [Thomas Devanneaux <Thomas.Devanneaux@enst.fr>] PR#3617
6834 *) Make documentation and error messages of APACI's --activate-module=FILE
6835 option more clear. [Jan Wolter <janc@wwnet.net>] PR#3995
6837 *) Fix the gcc version check (for enabling the `inline' facility) to
6838 really support all future gcc versions >= 2.7 until we know more.
6839 [John Tobey <jtobey@banta-im.com>] PR#3983
6841 *) Let APACI's configure script correctly complain for unknown --enable-XXX
6842 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
6844 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
6845 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
6846 possible buffer overflows. [Ralf S. Engelschall]
6848 *) Remove no longer used non-API function ap_single_module_init().
6849 [Ralf S. Engelschall]
6851 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
6854 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
6855 to make platform installations easier. [Wilfredo Sanchez]
6857 *) In configure, do not append the target name to the directory path if
6858 the path already contains "apache". [Ralf S. Engelschall]
6860 *) SIGPIPE is now ignored by the server core. The request write routines
6861 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
6862 correctly check for output errors and mark the connection as aborted.
6863 Replaced many direct (unchecked) calls to ap_b* routines with the
6864 analogous ap_r* calls. [Roy Fielding]
6866 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
6867 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
6868 Furthermore map lookups for non-existent keys are now cached as well.
6869 Additionally "txt" maps are now parsed with simple string functions
6870 instead of using ap_pregcomp(). As a side effect a bug that prevented
6871 the usage of keys containing the "," character was fixed.
6872 The changes drastically improve the performance when large rewrite maps
6874 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
6876 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
6877 other than GET, and const'd the definition of method in request_rec.
6880 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
6882 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
6883 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
6885 *) Add %V to mod_log_config, this logs the hostname according to the
6886 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
6887 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
6889 *) Add support for \n and \t to mod_log_config, can be used to produce
6890 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
6892 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
6894 *) Added informative error messages for failed munmap() and fseek() calls
6895 in http_core.c. [John Bley, Roy Fielding]
6897 *) Added some informative error messages for some failed malloc()
6898 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
6900 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
6901 is removed. This allows <Directory proxy:*> directives to work and
6902 prevents invalid requests from killing the process.
6903 [Brian Havard <brianh@kheldar.apana.org.au>]
6905 *) Reorganised FAQ document.
6906 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
6908 *) src/support/: The ApacheBench benchmark program was overhauled by
6909 David N. Welton: you can now have it generate an HTML TABLE, presumably
6910 for integration into other HTML sources. David updated the ab man page
6911 as well and added some missing descriptions. Thanks!
6912 [David N. Welton <davidw@prosa.it>]
6914 *) Win32: The filename validity checker now allows filenames containing
6915 characters in the range 0x80 to 0xff (for example accented characters).
6916 [Paul Sutton] PR#3890
6918 *) Added conditional logging based upon environment variables to
6919 mod_log_config. mod_log_referer and mod_log_agent
6920 are now deprecated. [Ken Coar]
6922 *) Allow apache acting as a proxy server to relay the real
6923 reason of a failure to a client rather than the "internal
6924 server error" it does currently. The general exposure mechanism
6925 can be triggered by any module by setting the "verbose-error-to"
6926 note to "*"; this allows more than just proxy errors to be exposed.
6927 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
6929 *) Moved man pages for ab and apachectrl to section 8.
6930 [Wilfredo Sanchez, Roy Fielding]
6932 *) Added -S option to install.sh so that options can be passed to
6933 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
6935 *) Tweak modules Makefile generated by Configure so that it handles
6936 the test case of no modules being selected. [chaz@reliant.com]
6938 *) Added a <LimitExcept method ...> sectioning directive that allows
6939 the user to assign authentication control to any HTTP method that
6940 is *not* given in the argument list; i.e., the logical negation
6941 of the <Limit> directive. This is particularly useful for controlling
6942 access on methods unknown to the Apache core, but perhaps known by
6943 some module or CGI script. [Roy Fielding, Tony Finch]
6945 *) Prevent apachectl from complaining if the PIDFILE exists but
6946 does not contain a process id, as might occur if the server is
6947 being rapidly restarted. [Wilfredo Sanchez]
6949 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
6951 *) Entity tag comparisons for If-Match and If-None-Match were not being
6952 performed correctly -- weak tags might cause false positives. Also,
6953 strong comparison wasn't properly enforced in all cases.
6954 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
6956 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
6959 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
6960 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
6962 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
6963 to util.c for parsing an HTTP header field value to extract the next
6964 list item, taking into account the possible presence of nested comments,
6965 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
6966 insignificant whitespace and lowercases non-quoted tokens.
6967 [Roy Fielding] PR#2065
6969 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
6970 code different from 500. This allows the proxy to, e.g., return
6971 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
6973 *) Fix ordering of language variants for the case where the traditional
6974 negotiation algorithm is being used with multiple language variants
6975 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
6977 *) Do not round the TCN quality calculation to 5 decimal places,
6978 unlike RFC 2296, because the calculation might need 12 decimal places
6979 to get the right result. [Roy Fielding]
6981 *) Remove unused code to disable transparent negotiation when
6982 negotiating on encoding only, as we now handle encoding too
6983 (though this is nonstandard for TCN), remove charset=ISO-8859-1
6984 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
6985 some debugging statements within mod_negotiation. [Koen Holtman]
6987 *) Fixed a rare memory corruption possibility in mod_dir if the index
6988 file is negotiable and no acceptable variant can be found.
6989 [Dean Gaudet, Roy Fielding, Martin Kraemer]
6991 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
6992 searching the Win32 registry for script interpreters.
6995 *) Win32: The compiled-in default filename for the error log is now
6996 error.log, which matches the default in the distributed httpd.conf.
6999 *) Win32: Any error messages from -i or -u command line options are now
7000 displayed on the console output rather than sent to the error log.
7001 Also the "Running Apache..." message is not output unless Apache is
7002 going to serve requests. [Paul Sutton]
7004 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
7005 and use a private significator ('$apr1$') to mark passwords as
7006 being smashed with our own algorithm. Also abstract the password
7007 checking into a new ap_validate_password() routine. [Ken Coar]
7009 *) Win32: The filename validity checker now allows "COM" but refuses
7010 access to "COM1" through "COM4". This allows filenames such
7011 as "com.name" to be served. [Paul Sutton] PR#3769.
7013 *) BS2000: Adapt to the new ufork() system call interface which will
7014 make subtasking easier on the OSD/POSIX mainframe environment.
7017 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
7018 ap_compat.h. [David White <david@persimmon.com>] PR#3725
7020 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
7021 use `.db' instead of `.pag' not only for FreeBSD, but also when
7022 the NDBM library looks like Berkeley-DB based.
7023 [Ralf S. Engelschall] PR#3773
7025 *) Add ability to handle DES or MD5 authentication passwords.
7026 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
7028 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
7030 *) SECURITY: Avoid some buffer overflow problems when escaping
7031 quoted strings. (This overflow was on the heap and we believe
7032 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
7034 *) Let src/Configure be aware of CFLAGS options starting with plus
7035 signs as it's the case for the HP/UX compiler.
7036 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
7038 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
7039 and check to see if the tar we wind up with supports '-h'.
7040 [Jim Jagielski] PR#3671
7042 *) A consistent and conservative style for all shell scripts has been
7043 implemented. Basically, all shell string tests use the traditional
7044 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
7045 to protect against bare null variable strings (ie: wrapping both
7046 sides with double quotes and prepending 'x'). 'x' was chosen
7047 because it's more universal and hopefully easier for old shell
7048 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
7051 *) The status module now prints out both the main server generation as
7052 well as the generation of each process. Also, the vhost info is
7053 printed with '?notable'. [Jim Jagielski]
7055 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
7056 and this makes its functions available to things in src/support.
7059 Changes with Apache 1.3.4
7061 *) Renamed macros status_drops_connection to ap_status_drops_connection
7062 and vestigial scan_script_header to ap_scan_script_header_err,
7063 mostly for aesthetic reasons. [Roy Fielding]
7065 *) The query switch "httpd -S" didn't exit after showing the
7066 vhost settings. That was inconsistent with the other query functions.
7069 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
7070 filename to the end of the STANDARD_MODULE_STUFF. Its
7071 presence at the beginning prevented reporting of the filename
7072 for modules compiled before 1 January 1999. [Ken Coar]
7074 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
7075 to detect and prevent access to special DOS device file names.
7076 [Paul Sutton, Ken Parzygnat]
7078 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
7079 and Makefile_win32_debug.txt (debug build) that work on Win95.
7080 Run each of the following from the src directory:
7081 nmake /f Makefile_win32.txt # compiles normal build
7082 nmake /f Makefile_win32.txt install # compiles and installs
7083 nmake /f Makefile_win32.txt clean # removes compiled junk
7084 nmake /f Makefile_win32_debug.txt # compiles debug build
7085 nmake /f Makefile_win32_debug.txt install
7086 nmake /f Makefile_win32_debug.txt clean
7089 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
7090 to build binary distributions. [Lars Eilebrecht]
7092 *) IndexOptions SuppressColumnSorting only turned off making
7093 the column headers anchors; you could still change the display
7094 order by manually adding a '?N=A' or similar query string to the
7095 URL. Now SuppressColumnSorting locks in the sort order so
7096 it can't be overridden this way. [Ken Coar]
7098 *) Added IndexOrderDefault directive to supply a default sort order
7099 for FancyIndexed directory listings. [Ken Coar] PR#1699
7101 *) Change the ap_assert macro to a variant that works on all platforms.
7102 [Richard Prinz <richard.prinz@cso.net>] PR#2575
7104 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
7105 search for an underscore on dlsym() (as it's already the case
7106 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
7108 *) Small fix for mod_env.html: The module was documented as to be _not_
7109 compiled into Apache per default, although it _IS_ compiled into
7110 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
7112 *) Instead of fixing a bug in the generation procedure for config.status (a
7113 backslash was missing) we remove the bug together with it's complete
7114 context because the special cases of the past can now no longer occur
7115 because of the recent magic for the --with-layout default.
7116 [Ralf S. Engelschall] PR#3590
7118 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
7119 making sure the src/support/ tools are _forced_ to be build last (they
7120 depend on other libraries).
7121 [Markus Theissinger <markus.theissinger@gmx.de>]
7123 *) Fix installation procedure: Now that os-inline.c is actually used (a
7124 recently fixed bug prevented this) we need to also install os-include.c
7125 in addition to os.h into the PREFIX/include/ location or building of
7126 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
7128 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
7129 allow us to distinguish between a garbled DSO (or even a file which isn't
7130 an Apache module DSO at all) and a DSO which doesn't match the current
7131 Apache API. [Ralf S. Engelschall] PR#3152
7133 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
7134 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
7135 match case insensitive (this especially avoids nasty patterns like
7136 `[tT][eE][sS][tT]'). Second two additional internal map functions
7137 `escape' and `unescape' were added which can be used to escape/unescape
7138 to/from hex-encodings in URLs parts (this is especially useful in
7139 combination with map lookups).
7140 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
7142 *) Renamed the macro escape_uri() to ap_escape_uri() which was
7143 forgotten (because it was a macro) in the symbol renaming process.
7144 [Ralf S. Engelschall]
7146 *) Fix some inconsistencies related to the scopes of directives. The only
7147 user visible change is that the directives `UseCanonicalName' and
7148 `ContentDigest' now use the (more correct) `Options' scope instead of
7149 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
7151 *) Using DSO, the Server token was being mangled. Specifically, the
7152 module's token was being added first before the Apache token. This
7153 has been fixed. [Jim Jagielski]
7155 *) Major overhaul of mod_negotiation.c, part 2.
7156 - properly handle "identity" within Accept-Encoding.
7157 - allow encoded variants in RVSA negotiation and let them appear in
7158 the Alternates field using the non-standard "encoding" tag-list.
7159 - fixed both negotiation algorithms so that an explicitly accepted
7160 encoding is preferred over no encoding if "identity" is not
7161 included within Accept-Encoding.
7162 - added ap_array_pstrcat() to alloc.c for efficient concatenation
7163 of large substring sequences.
7164 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
7167 *) Major overhaul of mod_negotiation.c, part 1.
7168 - cleanups to mod_negotiation comments and code structure
7169 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
7170 support for everything in the upcoming HTTP/1.1
7171 revision (draft-ietf-http-v11-spec-rev-06.txt).
7172 - language tag matching also handles tags with more than 2
7174 - empty Accept, Accept-Language, Accept-Charset headers are
7175 processed correctly; previously an empty header would make all
7176 values acceptable instead of unacceptable.
7177 - allowed for q values in Accept-Encoding
7178 - added support for transparent content negotiation (rfc2295 and
7179 rfc2296) (though we do not implement all features in these drafts,
7180 e.g. no feature negotiation). Removed old experimental version.
7181 - implemented 'structured entity tags' for better cache correctness
7182 (structured entity tags ensure that caches which can deal with Vary
7183 will (eventually) be updated if the set of variants on the server
7185 - this involved adding a vlist_validator element to request_rec
7186 - this involved adding the ap_make_etag() function to the global API
7187 - modified guessing of charsets used by Apache negotiation algorithm
7188 to guess 'no charset' if the variant is not a text/* type
7189 - added code to sort multiviews variants into a canonical order so that
7190 negotiation results are consistent across backup/restores and mirrors
7191 - removed possibility of a type map file resolving to another type map
7192 file as its best variant
7193 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
7195 *) RFC2396 allows the syntax http://host:/path (with no port number)
7196 but the proxy disallowed it (ap_proxy_canon_netloc()).
7197 [David Kristol <dmk@bell-labs.com>] PR#3530
7199 *) When modules update/modify the file name in the configfile_t structure,
7200 syntax errors will report the updated name, not the original one.
7201 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
7203 *) Correct some filename case assumptions from WIN32 to
7204 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
7206 *) For %v log ServerName regardless of the UseCanonicalName
7207 setting (similarly for %p). [Dean Gaudet]
7209 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
7210 rather late (too late for some invocations of TestCompile).
7211 This improves the make environment available to TestCompile and
7212 the *.module scripts. [Martin Kraemer]
7214 *) The hashbang emulation code in ap_execve.c would interpret
7215 #!/hashbang/scripts correctly, but failed to fall back to a
7216 standard shell for scripts which did NOT start with #!
7217 Now SHELL_PATH is started in these cases. [Martin Kraemer]
7219 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
7222 *) Update APXS manual page: some -q option arguments were missing
7223 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
7225 *) Cleanup the command line options: `-?' was documented to show
7226 the usage list but does it with an error because `?' is not a valid
7227 command. OTOH a lot of users expect `-h' to print such a usage list and
7228 instead are annoyed for ages by our huge unreadable list of directives.
7229 So we now changed the command line options this way:
7231 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
7232 very similar to the popular linker option.
7234 Intent: while -l gives the small list of modules, -L now gives the
7235 large list of directives implemented by these modules. This is also

7242 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
7243 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
7245 *) Removed recently introduced bugs and disfigurements in APACI:
7246 o fixed argument line processing: using $args was broken: It was not
7247 initialized and using args="$args $apc_option" and even args="$args
7248 \"$apc_option\"" fails in the second processing round for any arguments
7249 containing whitespaces. The only correct way is to use the construct
7250 "$@" (but not possible here) or iterate _both_ times over the implicit
7251 argument line (no argument to for-loop) which is what we now use.
7252 o make --with-layout=Apache the default without creating
7253 redundancy (copying the --with-layout block in the argument parsing
7254 loop). We achieve this by using the "$@" construct together with the
7255 `set' command to prepend --with-layout=Apache to the command line in
7256 case --with-layout is not used.
7257 o fixed auto-suffix handling now that config.layout exists.
7258 Paths which are auto-suffixed are marked with a trailing plus sign in
7259 config.layout and every path now can be marked this way (not only the
7260 four paths for which we do it currently). Additionally the suffix is
7261 no longer a static one. Instead it's now `/<target>' where <target> is
7262 the argument of the --target option or per default `httpd'.
7263 o allow also tabs (and only spaces) where we match whitespaces
7264 o various fixes and cleanups related to used shell coding style
7265 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7266 o trimmed output of --help to fit into 80 columns

7270 ap_single_module_init(), which are now used by mod_so to configure a module
7271 after loading. [Ralf S. Engelschall]
7273 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
7274 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
7275 of ap_config.h to allow serialized accept for multiport listens.
7276 [Roy Fielding, Curt Sampson] PR#3120
7278 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
7279 of ap_config.h that would skip several defines if DEFAULT_GROUP
7280 was overridden. [Roy Fielding]
7282 *) PORT: The I86 version of DGUX has support for strncasecmp and
7283 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
7285 *) Fix ordering of definitions in ap_config.h so that ap_inline is
7286 defined before it might be used. [Victor Khimenko]
7288 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
7289 [Tom Serkowski <tks@bsdi.com>] PR#3453
7291 *) Make generation of src/Configuration.apaci more robust: It failed to
7292 differenciate between modules when one module name was a postfix of
7293 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
7294 just XXX (think about totally non-standard names like "apache_ssl", too).
7295 [Ralf S. Engelschall] PR#3380
7297 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
7298 since 1.3b7) and make whitespace handling more robust (it failed horrible
7299 when whitespaces were present in the arguments of -D options).

7302 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
7303 creates an external package shadow tree in DIR before the local build
7304 shadow tree is generated under DIR. This way one can have the extracted
7305 Apache distribution tree read-only on NFS or CDROM and still build Apache
7306 from these sources. An automatically triggered VPATH-like mechanism is
7307 provided through the TOP variable, too.

7321 and the usage page was inconsistent with the functionality and manpage.

7324 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
7325 They can occur multiple times and their arguments (`xxx') are passed AS
7326 IS to the compiler/linker command. [Ralf S. Engelschall]
7328 *) Fixed possible (but harmless in practice) bug in the DBM lookup
7329 procedure of mod_rewrite: very long keys were truncated.
7330 [Ralf S. Engelschall]
7332 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
7333 identifier, currently "Apache" and "GNU" are pre-defined in the file
7334 config.layout. Custom layouts are possible by using FILE:ID as the
7335 argument where the layout ID is taken from FILE.
7337 The config.layout file consists of <Layout ID>..</Layout> sections
7338 where inside those sections "path_variable: path_value" pairs can be
7339 specified. These lines are converted to path_variable='path_value'.
7341 *) Add a DefaultLanguage directive so that files missing a language
7342 extension (e.g., .fr, .de) can be labelled as being some other
7343 default language. DefaultLanguage can appear in <Directory> and
7344 <Files> containers as well as .htaccess files. [Paul Sutton]
7347 *) Fix TARGET configuration when configuring and installing using
7348 APACI configure. TARGET now defines the basename of the configuration
7349 file, startup script, manual page, etc. log_error_core() now reports
7350 the server binary name given by argv[0]. TARGET can now also be defined
7351 with --target=TARGET parameter passed to APACI configure.

7375 and a redirect at the same time. [Lars Eilebrecht]
7377 *) Fallback to native compilers for IRIX-32 platform. It seems that
7378 a gcc 2.8.1 compiled apache is logging client addresses with all
7379 bits set (255.255.255.255). This is the second such problem caused
7380 by gcc 2.8.1 compiler. The first being broken semaphore locking.
7383 *) Updated mime.types to reflect current Internet media types
7384 and include a URL to the registry.

7391 used to set the document root directory (DOC_ROOT) and the suexec
7392 logfile (LOG_EXEC), respectively. Additionally the --layout option
7393 was changed to show more information about the suEXEC setup.

7431 since it often includes file path info. Enable sending of error-notes
7432 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
7434 *) http_config.c would respond with 501 (Method Not Implemented) if a
7435 content type handler was specified but could not be found, which
7436 should have been a 500 response. Likewise, mod_proxy.c would responsd
7437 with a 501 if the URI scheme is unrecognized instead of the correct
7438 response of 403 (Forbidden). [Roy Fielding]

7444 unavailable, an empty string was printed which was 2 bytes short.
7445 The size and description columns were therefore not aligned correctly.

7457 *) Add APACI --permute-module=foo:bar option which can be used to
7458 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
7459 in the Configuration[.apaci] file. Two special and important variants are
7460 supported for the option argument: first BEGIN:foo which permutes module
7461 mod_foo with the begin of the module list, i.e. it `moves' the module to
7462 the begin of the list (gives it lowest priority). And second foo:END
7463 which permutes mod_foo with the end of the module list, i.e. it `moves'
7464 the module to the end of the list (gives it highest priority).

7540 useful for PUT responses that result in 302 or 401. [Roy Fielding]
7542 *) Remove extra trailing whitespace from the getline results as part
7543 of the protocol processing, which is extra nice because it works
7544 between continuation lines, is almost no cost in the normal case
7545 of no extra whitespace, and saves memory. [Roy Fielding]

7689 *) Fix the recently introduced C header file checking: We now use the C
7690 pre-processor pass only (and no longer the complete compiler pass) to
7691 determine whether a C header file exists or not. Because only this way
7692 we're safe against inter-header dependencies (which caused horrible
7693 portability problems). The only drawback is that we now have a CPP
7694 configuration variable which has to be determined first (we do a similar
7695 approach as GNU Autoconf does here). When all fails the user still has
7696 the possibility to override it manually via APACI or src/Configuration.
7697 As a fallback for the header check itself we can directly check the
7698 existance of the file under /usr/include, too.

7731 because our GuessOS is still unaware of Digital UNIX versions and the
7732 -msym is just to optimize the DSO statup time a little bit it's safe and
7733 best when we leave it out now. [Ralf S. Engelschall] PR#2969
7735 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
7736 functions: First all three functions no longer fail on strings containing
7737 "%" chars and second ap_log_printf() no longer does a double-formatting
7738 (instead it directly passes through the message to be formatted to the
7739 real internal formatting function). [Ralf S. Engelschall] PR#2941
7741 *) Allow "Include" directives anywhere in the server config
7742 files (but not .htaccess files). [Ken Coar] PR#2727
7744 *) The proxy was refusing to serve CONNECT requests except to
7745 port 443 (https://) and 563 (snews://). The new AllowCONNECT
7746 directive allows the configuration of the ports to which a
7747 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
7749 *) mod_expires will now act on content that is not sent from a file
7750 on disk. Previously it would never add an Expires: header to
7751 any response that did not come from a file on disk; the only
7752 case where it still doesn't (and can't) add one for that type of
7753 content is if you are using a modification date based setting.

7768 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
7769 a common problem of (mis-administrated?) IIS servers, make the apache
7770 proxy immune to these errors (and ignore the duplicates, but log
7771 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
7773 *) The <IfModule and <IfDefine block starting directives now only
7774 allow exactly one argument. Previously, the optional negation
7775 character '!' could be separated by whitespace without a syntax
7776 error being reported, albeit defeating the IfModule functionality
7777 (enclosed directives would ALWAYS be executed). By using the
7778 stricter syntax, these hard-to-track errors can be avoided.
7781 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
7782 cause the standalone FancyIndexing directive to logically OR
7783 into any existing IndexOptions settings rather than wiping
7784 them out. [Ken Coar]
7786 *) Changes in ftp proxy: make URL parsing simpler by using the
7788 + Add display of the "current directory" in cases where it's
7789 different from the supplied path (e.g., ftp://user@host/ lives
7790 in /home/user, not in /, therefore clicking on "../" in the
7791 starting directory might send us to /home/).
7792 + When ftp login fails, (esp. when a user name was part of the
7793 URL already), we now return [401 Unauthorized ] to allow the
7794 browser to pop up an authorization dialog. This makes passwords
7795 slightly less visible (they don't appear in the regular log files)
7796 and implements a functionality that other www proxy servers
7800 *) Triggered by the recent "Via:" header changes, the proxy module would
7801 dump core for replies with invalid headers (e.g., duplicate
7802 "HTTP/1.0 200 OK" lines). These errors are now logged and the
7803 core dump is avoided. Also, broken replies are not cached.

7811 [Yves Arrouye <yves@apple.com>] PR#2866
7813 *) Replace the inlined information grabbing stuff for the configuration
7814 adjustment feature (no --without-confadjust) with calls to a new helper
7815 script `buildinfo.sh' which is both more flexible and already proofed to
7816 be more robust against platform differences. This mainly fixes the
7817 recently occured ``sed: command garbled: ...'' problems.

7838 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
7839 5 to 10 because there are some users out there who always have 5 to 8
7840 variables in one RewriteRule and had to patch mod_rewrite.h for every

7852 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
7854 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
7855 provide a way to trace API changes that add functionality but do
7856 not create a compatibility issue for precompiled modules, etc.
7857 See include/ap_mmn.h for more details. [Randy Terbush]
7859 *) Fix suexec installation under `make install root=xxx' situation.
7860 [Ralf S. Engelschall]
7862 *) Extend the output of the -V switch to include the paths of all
7863 compiled-in configuration files, if they were overridden at
7864 compile time, for least astonishment of the user.
7867 *) When READing a request in ExtendedStatus mode, the "old"
7868 vhost, request and client information is not displayed.
7871 *) STATUS is no longer available. Full status information now
7872 run-time configurable using the ExtendedStatus directive.
7875 *) SECURITY [CAN-1999-1199] (cve.mitre.org):
7876 Eliminate O(n^2) space DoS attacks (and other O(n^2)
7877 cpu time attacks) in header parsing. Add ap_overlap_tables(),
7878 a function which can be used to perform bulk update operations
7879 on tables in a more efficient manner.
7882 *) SECURITY: Added compile-time and configurable limits for
7883 various aspects of reading a client request to avoid some simple
7884 denial of service attacks, including limits on maximum request-line
7885 size (LimitRequestLine), number of header fields (LimitRequestFields),
7886 and size of any one header field (LimitRequestFieldsize). Also added
7887 a configurable directive LimitRequestBody for limiting the size of the
7888 request message body. [Roy Fielding]

7891 STATUS not defined. [Jim Jagielski]
7893 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
7895 *) Enhance mod_speling so that CheckSpelling can be used in

7904 ap_scan_script_header_err_core() [Doug MacEachern]
7906 *) The 'status' module will now show the process pid's and their
7907 state even without full STATUS accounting. [Jim Jagielski]
7909 *) Restore the client IP address to the error log messages, this
7910 was lost during the transition from 1.2 to 1.3. Add a new
7911 function ap_log_rerror() which takes a request_rec * and
7912 formats it appropriately. [Dean Gaudet] PR#2661
7914 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
7915 whitespace in input lines -- including within quoted strings.
7917 but leading and trailing whitespace should continue to be
7918 stripped [Martin Kraemer]
7920 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
7921 the ugly use of an env. variable and use command-line args for
7922 alternate $PATH. Make more like advanced 'type's as well.
7925 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
7926 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
7927 <alain.st-denis@ec.gc.ca>] PR#2736
7929 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
7931 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
7932 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
7933 directory was renamed to src/os/os2/ for consistency.
7934 [Brian Havard, Ralf S. Engelschall]
7936 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
7937 files (here modules) against other DSO files (here shared libraries).
7938 This is done by determining a subset of LIBS which can be safely used for
7939 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
7940 disabled for all platforms to avoid problems with this (experimental)
7941 rule. But we provide it now for those people how ran into problems and
7942 want to came out by forcing linking against DSOs.
7943 [Ralf S. Engelschall] PR#2587
7945 *) Fix suEXEC start message: Has to be of `notice' level to really get

7961 *) One more portability fix for APACI shadow tree support: Swap order of awk
7962 and sed in top-level configure script to avoid sed fails on some

8226 to external third-party libraries, etc.
8227 [Ralf S. Engelschall]
8229 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
8230 as <IfModule>..</IfModule> sections) which can be used to skip or process
8231 contained commands dependend of ``-D PARAMETER'' options on the command
8232 line. This can be used to achieve logical conditions like <IfDefine
8233 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
8234 and thus especially can be used for conditionally loading DSO-based
8235 modules via LoadModule, etc. [Ralf S. Engelschall]
8237 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
8239 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
8241 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
8242 truncated which forced following HTTP headers to be data in the HTTP
8243 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
8246 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
8247 in top-level configure script to avoid sed fails on some platforms (for
8248 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
8249 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
8251 *) Improve performance of directory listings (mod_autoindex) by comparing
8252 integer keys (last-modified and size) as integers rather than converting
8253 them to strings first. Also use a set of explicit byte tests rather
8254 than strcmp() to check for parent directory-ness of an entry. Oh, and
8255 make sure the parent directory (if displayed) is *always* listed first
8256 regardless of the sort key. Overall performance winnage should be good
8257 in CPU time, instruction cache, and memory usage, particularly for large
8258 directories. [Ken Coar]
8260 *) Add a tiny but useful goody to APACI's configure script: The generation
8261 of a config.status script (as GNU Autoconf does) which remembers the used
8262 configure command and hence can be used to restore the configuration by
8263 just re-running this script or for remembering the configuration between
8265 [Ralf S. Engelschall]
8267 *) Add httpd -t (test) option for running configuration syntax tests only.
8268 If something is broken it complains and exits with a return code
8269 non-equal to 0. This can be used manually by the user to check the Apache
8270 configuration after editing and is also automatically used by apachectl
8271 on (graceful) restart command to make sure Apache doesn't die on restarts
8272 because of a configuration which is now broken since the last (re)start.
8273 This way `apachectl restart' can be used inside cronjobs without having
8274 to expect Apache to be falling down. Additionally the httpd -t can be run
8275 via `apachectl configtest'.

8301 didn't match). [Ralf S. Engelschall]
8303 *) Add an additional "dummy" target to the "$(LIB)" target in generated

8386 *) Change usage of perror()+fprintf(stderr,...) in mod_rewrite to
8387 more proper ap_log_error() variants.

8393 [Ralf S. Engelschall] PR#2307
8395 *) Changes usage of perror/fprintf to stderr to more proper ap_log_error

8409 *) Propagate environment to CGI scripts correctly in Win32.
8410 [W G Stoddard <wgstodda@us.ibm.com>] PR#2294
8412 *) Some symbol renaming:
8413 ap_spawn_child_err became ap_spawn_child
8414 ap_spawn_child_err_buff became ap_bspawn_child
8415 spawn_child was obsoleted and moved to compat.h
8418 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
8419 programs: ap_spawn_child_err() is used and the Win32 case now uses
8420 CreateProcess() instead of a low-level execl() (which caused problems in
8421 the past under Win32).
8422 [Ralf S. Engelschall]
8424 *) A few cosmetics and trivial enhancements to APXS to make the
8425 generated Makefile more user friendly. [Ralf S. Engelschall]
8427 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
8428 was updated to use the normal apache error processing, thereby allowing
8429 proxy errors to be treated by ErrorDocument's as well. For this
8430 purpose, a new module-to-core communication variable "error-notes"
8431 was introduced; the proxy (and possibly other modules) communicates
8432 its error text using this variable. Its content is copied to a new
8433 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
8434 The old proxy special error routine ap_proxy_log_uerror()
8435 was replaced by regular ap_log_error() calls, many messages were made
8437 [Martin Kraemer] PR#494, 1259
8439 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
8442 *) Transform the configure message "You need root privileges for suEXEC"
8443 from a fatal error into a (more friendly) warning because the building
8444 ("make") of Apache we can allow, of course. Root privileges are needed
8445 only for the installation step ("make install"). So make sure the
8446 user is aware of this fact but let him proceed as long as he can.
8447 [Ralf S. Engelschall] PR#2288
8449 *) Renamed three more functions to common ap_ prefix which we missed at the
8450 Big Symbol Renaming because they're #defines and not real C functions:

8452 [Ralf S. Engelschall]
8454 *) A zero-length name after a $ in an SSI document should cause

8465 Changes with Apache 1.3b7
8467 *) Make sure a MIME-type can be forced via a RewriteRule even when no
8468 substitution takes place, for instance via the following rule:
8469 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
8470 requested by users in the past to force a single script without a .cgi
8471 extension and outside any cgi-bin dirs to be executed as a CGI program.

8474 *) A fix for protocol issues surrounding 400, 408, and

8479 *) Fix discrepancy in proxy_ftp.c which was causing failures when
8480 trying to connect to certain ftpd's, such as anonftpd.
8481 [Rick Ohnemus <rick@ecompcon.com>]
8483 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
8484 logfile instead of fiddling around itself with child spawning stuff.
8485 [Ralf S. Engelschall]
8487 *) Made RefererIgnore case-insensitive.
8489 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
8492 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
8493 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
8496 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
8498 *) Fix support script `dbmmanage': It was unable to handle some sort
8499 of passwords, especially passwords with "0" chars.
8500 [Ralf S. Engelschall] PR#2242
8502 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
8503 [Ben Laurie] PR#2238
8505 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
8506 library), so CGI handling has been changed to use Win32 native handles
8507 instead of C file descriptors.
8508 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
8510 *) The proxy cache would store an incorrect content-length in the cached
8511 file copy after a cache update. That resulted in repeated fetching
8512 of the original copy instead of using the cached copy.
8513 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
8515 *) The Makefiles assumed that DSO files are build via $(LD). This
8516 is broken for two reasons: First we never defined at least LD=ld
8517 somewhere to make sure this works (it was silently assumed that most Make
8518 provide a built-in LD definition - ARGL!) and second using the generic LD
8519 variable is not the truth. Instead a special variable named LD_SHLIB is
8520 reasonable because although "ld" is usually the default, the command for
8521 building DSO files can be "libtool" or even "cc" on some systems.
8522 [Ralf S. Engelschall]
8524 *) Replace the AddVersionPlatform directive with ServerTokens which
8525 provides for more control over the format of the Server:
8526 header line. SERVER_SUBVERSION is no longer supported;
8527 all module should use the ap_add_version_component()
8528 API function instead. [Jim Jagielski]
8530 *) Support for the NCR MP/RAS 3.0
8531 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
8533 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
8534 not retrieved in src/Configure and thus was not useable.
8535 [Ralf S. Engelschall]
8537 *) Various Makefile consistency cleanups:
8538 - make OSDIR also automatically be relative to src/ like INCDIR
8539 - SUBDIRS is now generated in src/Makefile only and not in
8540 Makefile.config because it is a local define for this location.
8541 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
8542 any Makefile but make sure that at least the "-K inline" is kept in
8544 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
8545 - updated the dependencies theirself
8546 - removed not existing SHLIB variable from "clean" targets
8547 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
8548 already exists and OBJS_PIC are also just plain objects and have not
8549 directly to do with "shared" things. The only difference is that they
8550 contain PIC. So OBJS_PIC is the more canonical name.
8551 - Updated the Makefile-dependency lines for OBJS_PIC
8552 - Removed the Makefile-dependency line in Configure to avoid double
8554 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
8555 of xxx.lo as GNU libtool does with its PIC objects
8556 - reduce local complexity in modules Makefile.tmpl by moving the last
8557 existing target "depend" to the generation section in Configure, too.
8558 - removed the historical $(SPACER) which was used in the past together
8559 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
8560 is no longer needed.
8561 - force the build and run of the gen_xxx programs under main/ as the
8562 first step before building the objects because it looks cleaner
8563 [Ralf S. Engelschall]
8565 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
8568 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
8571 *) WIN32: Don't force ISAPI headers to finish with \n.
8572 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
8574 *) When opening "configuration" files (like httpd.conf, htaccess
8575 and htpasswd), Apache will not allow them to be non-/dev/null
8576 device files. This closes a DoS hole. At the same time,
8577 we use ap_pfopen to open these files to handle timeouts.
8578 [Jim Jagielski, Martin Kraemer]
8580 *) Apache will now log the reason its httpd children exit if they exit
8581 due to an unexpected signal. (It requires a new porting define,
8582 SYS_SIGLIST, which if defined should point to a list of text
8583 descriptions of the signals available. See PORTING.) [Dean Gaudet]
8585 *) WIN32: chdir() doesn't make sense in a multithreaded environment
8586 like WIN32. Before, Win32 CGI's could have had sporadic failures
8587 if a chdir call from one thread was made between another chdir call
8588 and a spawn in another thread. So, for now don't chdir for CGI scripts
8589 in WIN32. The current CGI "spec" is unclear as to whether it's
8590 necessary. Long-term fix is to either serialize the chdir/spawn combo
8591 or use WIN32 native calls to spawn a process. This temp fix was
8592 necessary to remove this as a showstopper for 1.3's release.
8595 *) Cleanup the suEXEC support in APACI and make it more safe:
8596 1. Add big fat hint in INSTALL about risks and to read the
8597 htdocs/manual/suexec.html document before using the suexec-related
8599 2. Make sure the user has at least provided one --suexec-xxxx option
8600 (specifies suEXEC parameters) in addition to --enable-suexec option.
8601 If only --enable-suexec is given APACI stops with a hint to INSTALL
8602 and htdocs/manual/suexec.html documents.
8603 3. Provide two additional --suexec-xxxx options to make the suEXEC
8604 configuration complete (especially for package maintainers who else
8605 had to patch the source tree) by providing ways to configure minimal
8606 UID/GID and safe PATH, too.
8607 [Ralf S. Engelschall]
8609 *) Cleanup of the `configure --shadow' process:
8610 - make sure the configure script creates its temporary files in the
8611 shadow tree to avoid conflicts with parallel configure runs
8612 - removed unnecessary option "-r" from "rm" call for Makefiles
8613 - make sure the configure scripts creates the shadow-wrapper Makefile
8614 only when no shadow trees already exists
8615 - make sure "make distclean" removes the shadow-wrapper Makefile but only
8616 when no more shadow trees exists
8617 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
8618 as fast (in the past it needed 70sec, now it runs just 38sec)
8619 - make sure CVS does not complain about the created files
8620 Makefille.<gnutriple> and directories src.<gnutriple>
8621 [Ralf S. Engelschall]
8623 *) Added the ap_add_version_component() API routine and the
8624 AddVersionPlatform core directive. The first allows modules to
8625 declare themselves in the Server response header field value,
8626 augmenting the SERVER_SUBVERSION define in the Configuration file
8627 with run-time settings (more useful in a loadable-module environment).
8628 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
8629 into the server version string. [Ken Coar] PR#2056
8631 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
8634 *) Emit the "Accept-Range" header for the default handler.
8635 [Brian Behlendorf] PR#1464
8637 *) Add a note to httpd.conf-dist that apache will on some systems fail
8638 to start when the Group # is set to a negative or large positive value.
8641 *) Make sure the module execution order is correct even when some modules
8642 are loaded under runtime (`LoadModule') via the DSO mechanism:
8643 1. The list of loaded modules is now a dynamically allocated one
8644 and not the original statically list from modules.c
8645 2. The loaded modules are now correctly setup by LoadModule for
8646 later use by the AddModule command.
8647 3. When the DSO mechanism for modules is used APACI's `install'
8648 target now enables all created `LoadModule' lines per default because
8649 this is both already expected by the user _and_ needed to avoid
8650 confusion with the next point and reduces the Makefile.tmpl complexity
8651 4. When the DSO mechanism for modules is used, APACI's `install'
8652 target now additionally makes sure the module list is reconstructed
8653 via a complete `ClearModuleList+AddModule...' entry.
8654 5. The support tool `apxs' now also makes sure an AddModule command
8655 is added in addition to the LoadModule command.
8656 6. The modules.c generation was extended to now contain two
8657 comments to make sure no one is confused by the confusing terminology
8658 of loading/linking (we use load=link+load & link=activate instead of
8659 the obvious load=activate & link=link :-( )
8660 This way now there is no longer a difference under execution time between
8661 statically and dynamically linked modules.
8662 [Ralf S. Engelschall]
8664 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
8665 Big Symbol Renaming. [Ralf S. Engelschall]
8667 *) Add a comment to mod_example.c showing the format of a FLAG command
8670 *) Standardized the time format in mod_status to match that of other
8671 places in the code (e.g. DATE_GMT). PR#1551
8673 *) Fix handling of %Z in timefmt strings for those platforms with no time
8674 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
8677 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
8678 feature compatible with 'UseCanonicalName off' by changing
8679 r->server->server_hostname to ap_get_server_name(). And I changed some
8680 functions which use r->server->port to use ap_get_server_port() instead,
8681 because if there's no Port directive in the config r->server->port is 0.
8684 *) get/set_module_config are trivial enough to be better off inline. Worth
8685 1.5% performance boost. [Dean Gaudet]
8687 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
8688 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
8691 *) [BS2000 security] BS2000 needs an extra authentication to initialize
8692 the task environment to the unprivileged User id. Otherwise CGI scripts
8693 would have a way to gain super user access. [Martin Kraemer]
8695 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
8696 absolute path, only log base name of logging source as is done
8697 in unix. [Martin Kraemer]
8699 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
8700 the encoding type from the Accept-Encoding header (if it's there)
8701 and use it in the response, as that's probably what it'll be expecting.
8702 [Ronald.Tschalaer@psi.ch]
8704 *) Fix to mod_alias: translate_alias_redir is dealing with
8705 a URI, not a filename, so the check for drive letters for win32
8706 and emx is not necessary. [Dean Gaudet]
8708 *) WIN32: Allow .cmd as an executable extension.
8709 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
8711 *) Make Apache header files, and some variables, C++ friendly.

8714 *) Child processes can now "signal" (by exiting with a status
8715 of APEXIT_CHILDFATAL) the parent process to abort and
8716 shutdown the server if the error in the child process was
8717 fatal enough. [Jim Jagielski]
8719 *) mod_autoindex's find_itme() was sensitive to MIME type case.
8720 [Jim Jagielski] PR#2112
8722 *) Make sure the referer_log and agent_log entries in the default httpd.conf
8723 file are also adjusted for the actual relative installation paths.

8726 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
8728 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
8731 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
8732 Additionally the checks for finding the vendor DSO library were moved
8733 from mod_so.c to Configure because first it needs $PLAT etc. and second
8734 mod_so already uses an abstraction layer and does not fiddle with the
8735 vendor functions itself.
8736 [Jens-Uwe Mager, Ralf S. Engelschall]
8738 *) PORT: Some optimization defines for NetBSD
8739 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
8741 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
8742 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
8744 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
8745 AIX variants should work fine, too. Even AIX 3.x should work). This is
8746 accomplished by using the free DSO emulation code from Jens-Uwe Mager
8747 which we put into a os/unix/os-dso-aix.c file.
8748 [Ralf S. Engelschall]
8750 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
8751 that we should use NET_SIZE_T == int but the include files force size_t.
8752 [Ralf S. Engelschall]
8754 *) Fix two bugs in select() handling in http_main.c.
8757 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
8758 is unset (as it is in situations like timeouts) where it is unclear
8759 whether errno is set or not. [Martin Kraemer]
8761 *) Just having APACI's localstatedir is too general and not enough for most
8762 of the systems. 1.3b6 again required manual APACI patches by package
8763 maintainers from Red Hat and FreeBSD because for their filesystem layout a
8764 little bit more flexibility in configuring the paths is needed. Hence we
8765 provide three additional configure options (--runtimedir, --logfiledir,
8766 --proxycachedir) which now can be used for more granular adjustments if
8767 --localstatedir is not enough to fit the particular needs. As a nice
8768 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
8769 [Ralf S. Engelschall]
8771 *) Make the install root for "make install" in APACI's Makefile overrideable
8772 by package authors. This way we are even more friendly to package
8773 maintainers (especially Debian and Red Hat) who build for the real prefix
8774 via "configure --prefix=/<real>" but use a different local prefix via
8775 "make root=/tmp/apache install" for rolling the package without bristling
8776 the target location on their system.
8777 [Ralf S. Engelschall]
8779 *) Workaround sed limitations in APACI's configure script by now
8780 substituting in chunks of 50 commands (because for instance HPUX's vendor
8781 sed has a limit of max. 98 commands)
8782 [Ralf S. Engelschall] PR#2136
8784 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
8785 [Ralf S. Engelschall] PR#2140
8787 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
8788 RENAMING process because they are defined as pre-processor macros instead
8789 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
8790 [Ralf S. Engelschall]
8792 *) Workaround braindead AWK's when generating ap_config.h: The split() and
8793 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
8794 [Ralf S. Engelschall] PR#2139
8796 *) Various bugfixes and cleanups for the APACI configure script:
8797 o fix IFS handling for _nested_ situation
8798 o fix Perl interpreter search: take first one found instead of last one
8799 o fix DSO consistency check
8800 o print error messages to stderr instead of stdout
8801 o add install-quiet for --shadow situation to Makefile stub
8802 o reduce complexity by avoiding sed-hacks for rule and module list loops
8803 [Ralf S. Engelschall]
8805 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
8807 *) Make sure the input field separator (IFS) shell variable is explicitly
8808 initialized correctly before _every_ `for' loop and also restored after
8809 the loops. [Ralf S. Engelschall]
8811 *) Make sure that "make install" doesn't overwrite the `mime.types' and
8812 `magic' files from an existing Apache installation. Because people often
8813 customize these for own MIME and content types.
8814 [Ralf S. Engelschall]

8819 *) Fix the path to the ScoreBoardFile in the install-config target, too.
8820 [Ralf S. Engelschall] PR#2105
8822 *) Let "configure" clear out the users parameters (provided as shell
8823 variables) to avoid side-effects in "src/Configure" when the user
8824 exported them (which is not needed, but some users do it).
8825 [Ralf S. Engelschall] PR#2101
8827 *) Provide backward compatibility from some old src/Configuration.tmpl
8828 parameter names to the canonical Autoconf-style shell variable names. For
8829 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
8830 but a hint message is displayed. [Ralf S. Engelschall]

8833 CGI scripts from an existing Apache installation.
8834 [Ralf S. Engelschall, Jim Jagielski] PR#2084
8836 *) Make `configure --compat' more "compatible" by first
8837 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
8838 second by making sure the "avoid-bristling-suffix" /apache is not
8839 appended to sysconfdir, datadir, localstatedir and includedir when
8840 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]

8849 [Ralf S. Engelschall] PR#2089
8851 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
8853 *) If you start apache with the -S command line option it will dump
8854 out the parsed vhost settings. This is useful for folks trying
8855 to figure out what is wrong with their vhost configuration.
8856 (Other dumps may be added in the future.) [Dean Gaudet]
8858 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
8859 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
8862 *) Because /usr/local/apache is the default prefix the ``configure
8863 --compat'' option no longer has to set prefix, again. This way the
8864 --compat option honors a leading --prefix option. [Lars Eilebrecht]
8866 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
8867 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
8868 to avoid "discard const" warnings. [Ralf S. Engelschall]
8870 *) If a specific handler is set for a file yet the request still
8871 ends up being handled by the default handler, log an error
8872 message before handling it. This catches things such as trying
8873 to use SSIs without mod_include enabled. [Marc Slemko]
8875 *) Fix error logging for the startup case where ap_log_error() still uses
8876 stderr as the target. Now the default log level is honored here, too.
8877 [Ralf S. Engelschall]
8879 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
8880 long" errors when generating the MODULES entry for src/Makefile
8881 [Ben Hyde, Ralf S. Engelschall]
8883 *) Make sure src/Configure doesn't complain about the old directory
8884 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
8886 Changes with Apache 1.3b6
8888 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
8890 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
8891 interface via the similar but proprietary HP/UX shl_xxx-style system
8892 calls. [Ralf S. Engelschall]
8894 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
8895 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
8896 Make. [Ralf S. Engelschall]
8898 *) ++++ THE BIG SYMBOL RENAMING ++++
8899 To avoid symbol clashes with third-party code compiled into the server,
8900 we globally applied the prefix "ap_" to the following classes of
8902 - Apache provided general functions (e.g., ap_cpystrn)
8903 - Public API functions (e.g., palloc, bgets)
8904 - Private functions which we can't make static (because of
8905 cross-object usage) but should be (e.g., new_connection)
8906 For backward source compatibility a new header file named compat.h was
8907 created which provides defines for the old symbol names and can be used
8908 by third-party module authors.
8911 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
8912 problem under SVR4 is that there is no command flag to force the linker
8913 to export the global symbols of the httpd executable therewith they are
8914 available to the DSO's. Instead of problematic hacks like creating a
8915 dummy.so file (containing dummy references to all global symbols) the
8916 httpd binary is linked against, we use a clean trick stolen from Perl 5:
8917 Placing the Apache core code itself into a DSO library named libhttpd.so.
8918 This way the global symbols _HAVE_ to be exported and thus are available
8919 to any manually loaded DSO's under runtime. To reduce the impact to the
8920 user to null we go even further and create a stub httpd executable which
8921 automatically keeps track of the DSO library loading itself and thus
8922 hides the complete mechanism from the user. Although the generation of
8923 this DSO library is automatically triggered for platforms which
8924 essentially need it (mostly all SVR4-derivates) it can be also enabled
8925 manually via the Rule SHARED_CORE. This can be interesting in the future
8926 where we perhaps exploit this libhttpd.so mechanism for providing nifty
8927 features like graceful upgrades, or whatever.
8928 [Ralf S. Engelschall, Martin Kraemer]
8930 *) Build the libraries before building the rest of the tools. [Ben Hyde]
8932 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
8933 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
8934 conventions while "clean" removes only stuff created by "all" targets,
8935 "distclean" additionally removes the stuff from the configuration
8936 process. This way "make distclean" (hence the name) provides a fresh
8937 source tree as it was for distribution.
8938 [Ralf S. Engelschall]
8940 *) Allow top-level (APACI) Makefile to break on build errors
8941 the same way the src/ subtree Makefiles breaks on them by replacing the
8942 initial APACI sed-subdir-display-kludge with a more clean
8943 variable-passing-solution: variable SDP can optionally hold the subdir
8944 prefix which is consistently used for displaying the subdir movement.
8945 This way even the top-level Makefile can stop correctly on errors as the
8946 user expects. [Ralf S. Engelschall]
8948 *) Fixed ordering of argument checks for RewriteBase directive.
8949 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
8951 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
8952 indicating that a module is being compiled for dynamic loading. Also
8953 remove #define IS_MODULE from modules and add SHARED_MODULE define
8954 to the mak/dsp files. [Alexei Kosut]
8956 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
8957 since we are now logging APLOG_WARNING by default. [Roy Fielding]
8959 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
8961 *) Add documentation file and src/Configuration.tmpl entry for the
8962 experimental mod_mmap_static module. Because although it is and marked as
8963 an experimental one it is distributed and thus should be documented and
8964 prepared for configuration the same way as all others modules.
8965 [Ralf S. Engelschall]
8967 *) Add query (-q) option to apxs support tool to be able to manually query
8968 specific settings from apxs. This is needed for instance when you
8969 manually want to access Apache's header files and you need to assemble
8970 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
8971 [Ralf S. Engelschall]
8973 *) Now src/Configure uses a fallback strategy for the shared object support
8974 on platforms where no explicit information is available: If a Perl
8975 installation exists we ask it about its shared object support and if it's
8976 the dlopen-style one we shamelessly guess the compiler and linker flags
8977 for creating shared objects from Perls knowledge. Of course, the user is
8978 warning about what we are doing and informed that he should send us
8979 the guessed flags when they work. [Ralf S. Engelschall]
8981 *) Provide APACI --without-support option to be able to disable the build
8982 and installation of the support tools from the src/support/ area.
8983 Although its useful to have these installed per default we should provide
8984 a way to compile and install without them for backward-compatibility.
8985 [Ralf S. Engelschall]
8987 *) Add of the new APache eXtenSion (apxs) support tool for building and
8988 installing modules into an _already installed_ Apache package through the
8989 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
8990 this approach actually doesn't need the Apache source tree. The
8991 (APACI-installed) server package is enough, because this now includes the
8992 Apache C header files (PREFIX/include) and the new APXS tool
8993 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
8994 module authors to build their Apache modules _OUTSIDE_ the Apache source
8995 tree while avoiding them to fiddle around with the totally platform
8996 dependend way of compiling DSO files. The tool supports all ranges of
8997 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
8998 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
8999 on-the-fly generate a minimalistic Makefile and sample module for the
9000 first step to provide both a quick success event and to demonstrate the
9001 APXS mechanism to module authors. [Ralf S. Engelschall]
9003 *) Fix core dumps in use of CONNECT in proxy.
9004 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
9006 *) Modify the log directives in httpd.conf-dist files to use CustomLog
9007 so that users have examples of how CustomLog can be used.
9010 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
9011 the Apache distribution tree. Until Apache 1.3 there was no real
9012 out-of-the-box batch-capable build and installation procedure for the
9013 complete Apache package. This is now provided by a top-level "configure"
9014 script and a corresponding top-level "Makefile.tmpl" file. The goal is
9015 to provide a GNU Autoconf-style frontend which is capable to both drive
9016 the old src/Configure stuff in batch and additionally installs the
9017 package with a GNU-conforming directory layout. Any options from the old
9018 configuration scheme are available plus a lot of new options for flexibly
9019 customizing Apache. [Ralf S. Engelschall]
9021 *) The floating point ap_snprintf code wasn't threadsafe.
9022 Had to remove the HAVE_CVT macro in order to do threadsafe
9023 calling of the ?cvt() floating point routines. [Dean Gaudet]
9025 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
9027 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
9028 [Jim Jagielski] PR#1901
9030 *) BUG: Configure was using TCC and CC inconsistently. Make sure
9031 Configure knows which CC we are using. [Jim Jagielski]
9033 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
9034 was defined in a parent directory. [Lars Eilebrecht]
9036 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
9037 a generic printf-style routine that can call arbitrary output
9038 routines. Use this to replace http_bprintf.c. Add new routines
9039 psprintf(), pvsprintf() which allocate the exact amount of memory
9040 required for a string from a pool. Use psprintf() to clean up
9041 various bits of code which used ap_snprintf()/pstrdup().
9044 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
9045 ap_snprintf() has different semantics and formatting codes than
9046 snprintf(). [Dean Gaudet]
9048 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
9049 is necessary on at least Solaris where the /etc/rc?.d scripts
9050 are run with these signals ignored, and "SIG_IGN" settings are
9051 maintained across exec().
9052 [Rein Tollevik <reint@sys.sol.no>] PR#2009
9054 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
9055 used instead of lstat() and thus this flag didn't work as expected.

9058 *) Fix the proxy pass-through feature of mod_rewrite for the case of
9059 existing QUERY_STRING now that mod_proxy was recently changed because of
9060 the new URL parsing stuff. [Ralf S. Engelschall]
9062 *) A few changes to scoreboard definitions which helps gcc generate
9063 better code. [Dean Gaudet]
9065 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
9066 be a signed bitfield. So mark a few bitfields as signed to
9067 ensure correct code. [Dean Gaudet]
9069 *) The default for HostnameLookups was changed to Off, but there
9070 was a problem and it wasn't taking effect. [Dean Gaudet]
9072 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
9075 *) After a SIGHUP the listening sockets in the parent weren't
9076 properly marked for closure on fork().
9077 [Jürgen Keil <jk@tools.de>] PR#2000
9079 *) Allow %2F in two situations: 1) it is in the query part of the URI,
9080 therefore not exposed to %2F -> '/' translations and 2) the request
9081 is a proxy request, so we're not dealing with a local resource anyway.
9082 Without this, the proxy would fail to work for any URL's with
9083 %2f in them (occurs quite often in
9084 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
9086 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
9088 *) Make the shared object compilation command more portable by avoiding
9089 the direct combination of `-c' & `-o' which is not honored by some
9090 compilers like UnixWare's cc. [Ralf S. Engelschall]
9092 *) WIN32: the proxy was creating filenames missing the last four
9093 characters. While this normally doesn't stop anything from
9094 working, it can result in extra collisions.
9095 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
9097 *) Now mod_proxy uses the response string (in addition to the response status
9098 code) from the already used FTP SIZE command to setup the Content-Length
9099 header if available. [Ralf S. Engelschall] PR#1183
9101 *) Reanimated the (still undocumented) proxy receive buffer size directive:
9102 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
9103 name was really too generic, added documentation for this directive to
9104 the mod_proxy.html and corrected the hyperlink to it in the
9105 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
9107 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
9108 faster [Martin Kraemer]
9110 *) Make Configure die when you give it an unknown command switch.
9113 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
9114 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
9115 and per default compiled support programs have manual pages - just to
9116 document our stuff a little bit more and to be able to do really
9117 Unix-like installations ;-) [Ralf S. Engelschall]
9119 *) Major cleanups to the Configure script to make it and its generated
9120 Makefiles again readable and maintainable: add SRCDIR option, removed
9121 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
9122 generated sections, consequently added Makefile headers with inheritance
9123 information, added subdir movement messages for easier following where
9124 the build process currently stays (more verbose then standard Make, less
9125 verbose than GNU make), same style to comments in the Configure script,
9126 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
9128 *) Add the new ApacheBench program "ab" to src/support/: This is derived
9129 from the ZeusBench benchmarking program and can be used to determine the
9130 response performance of an Apache installation. This version is
9131 officially licensed with Zeus Technology, Ltd. See the license agreement
9132 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
9133 [Ralf S. Engelschall]
9135 *) API: Various core functions that are definately not part of the API
9136 have been made static, and a few have been marked API_EXPORT. Still
9137 more have been marked CORE_EXPORT and are not intended for general
9138 use by modules. [Doug MacEachern, Dean Gaudet]
9140 *) mod_proxy was not clearing the Proxy-Connection header from
9141 requests; now it does. This did not violate any spec, however
9142 causes poor interactions when you are talking to remote proxies.
9143 [Marc Slemko] PR#1741
9145 *) Various cleanups to the command line interface and manual pages.
9146 [Ralf S. Engelschall]
9148 *) cfg_getline() was not properly handling lines that did not end
9149 with a line termination character. [Marc Slemko] PR#1869, 1909
9151 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
9153 *) Clean up some undocumented behavior of mod_setenvif related to
9154 "merging" two SetEnvIf directives when they match the same header
9155 and regex. Document that mod_setenvif will perform comparisons in
9156 the order they appear in the config file. Optimize mod_setenvif by
9157 doing more work at config time rather than at runtime.
9160 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
9161 to allow for modules to overrule them and to reduce redefinition
9162 warnings [Jim Jagielski]
9164 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
9167 *) Making the hard-coded cross-module function call mime_find_ct() (from
9168 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
9169 checking is really called even for proxy requests except for URLs with
9170 HTTP schemes (because there we can optimize by not running the type
9171 checking hooks due to the fact that the proxy gets the MIME Content-type
9172 from the remote host later). This change cleans up mod_mime by removing
9173 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
9174 especially unbundles mod_proxy and mod_mime. This way they both now can
9175 be compiled as shared objects and are no longer tied together.
9176 [Ralf S. Engelschall]
9178 *) util.c cleanup and speedup. [Dean Gaudet]
9180 *) API: Clarification, pstrndup() will always copy n bytes of the source
9181 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
9183 *) Mark module command_rec and handler_rec structures const so that they
9184 end up in the read-only data section (and are friendlier to systems
9185 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
9187 *) Add check to the "Port" directive to make sure the specified
9188 port is in the appropriate range. [Ben Hyde]
9190 *) Performance improvements to invoke_handler().
9191 [Dmitry Khrustalev <dima@bog.msu.su>]
9193 *) Added support for building shared objects even for library-style modules
9194 (which are built from more than one object file). This now provides the
9195 ability to build mod_proxy as a shared object module. Additionally
9196 modules like mod_example are now also supported for shared object
9197 building because the generated Makefiles now no longer assume there is at
9198 least one statically linked module. [Ralf S. Engelschall]
9200 *) API: Clarify usage of content_type, handler, content_encoding,
9201 content_language and content_languages fields in request_rec. They
9202 must always be lowercased; and the strings pointed to shouldn't
9203 be modified (you must copy them to modify them). Fix a few bugs
9204 related to this. [Dean Gaudet]
9206 *) API: Clarification: except for RAW_ARGS, all command handlers can
9207 treat the char * parameters as permanent, and modifiable. There
9208 is no need to pstrdup() them. Clean up some needless pstrdup().
9211 *) Now mod_so keeps track of which module shared objects with which names
9212 are loaded and thus avoids multiple loading and unloading and irritating
9213 error_log messages. [Ralf S. Engelschall]
9215 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
9216 environment variable in the apache core. But that tweaking interferes
9217 with mod_setenv. So don't tweak if the user has specified an explicit
9218 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
9220 *) rputs() did not calculate r->sent_bodyct properly.
9221 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
9223 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
9224 name, or left unset if this value is unavailable. Apache was setting
9225 it to the IP address when unavailable.
9226 [Tony Finch <fanf@demon.net>] PR#1925
9228 *) Various improvements to the configuration and build support for compiling
9229 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
9230 OSF1 support with GCC and vendor compilers was added. This way shared
9231 object support is now provided out-of-the-box for FreeBSD, Linux,
9232 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!

9235 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
9236 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
9237 and USE_OS2_SCOREBOARD. [Dean Gaudet]
9239 *) Fix one more special locking problem for RewriteMap programs in
9240 mod_rewrite: According to the documentation of flock(), "Locks are on
9241 files, not file descriptors. That is, file descriptors duplicated
9242 through dup(2) or fork(2) do not result in multiple instances of a lock,
9243 but rather multiple references to a single lock. If a process holding a
9244 lock on a file forks and the child explicitly unlocks the file, the
9245 parent will lose its lock.". To overcome this we have to make sure the
9246 RewriteLock file is opened _AFTER_ the childs were spawned which is now
9247 the case by opening it in the child_init instead of the module_init API
9248 hook. [Ralf S. Engelschall] PR#1029
9250 *) Change to Location and LocationMatch semantics. LocationMatch no
9251 longer lets a single slash match multiple adjacent slashes in the
9252 URL. This change is for consistency with RewriteRule and
9253 AliasMatch. Multiple slashes have meaning in URLs that they do
9254 not have in (some) filesystems. Location on the other hand can
9255 be considered a shorthand for a more complicated regex, and it
9256 does match multiple slashes with a single slash -- which is
9257 also consistent with the Alias directive.
9258 [Dean Gaudet] related PR#1440
9260 *) Fix bug with mod_mime_magic causing certain files, including files
9261 of length 0, to result in no response from the server.
9264 *) The Configure script now generates src/include/ap_config.h which
9265 contains the set of defines used when Apache is compiled on a platform.
9266 This file can then be included by external modules before including
9267 any Apache header files in case they are being built separately from
9268 Apache. Along with this change, a couple of minor changes were
9269 made to make Apache's #defines coexist peacefully with any autoconf
9270 defines an external module might have. [Rasmus Lerdorf]
9272 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9273 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9274 chance by the API to initialize its per-server configuration and thus
9275 receives the wrong one from the main server. This is now avoided by
9276 remembering the server together with the config structure while
9277 configuring and later assuming there is no config when we see a
9278 difference between the remembered server and the one calling us.
9279 [Ralf S. Engelschall] PR#1790
9281 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9282 is automatically disabled under configure time when the dbm_xxx functions
9283 are not available. Second, two heavy source code errors in the DBM
9284 support code were fixed. This makes DBM RewriteMap's usable again after
9285 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9287 *) Now all configuration files support Unix-style line-continuation via
9288 the trailing backslash ("\") character. This enables us to write down
9289 complex or just very long directives in a more readable way. The
9290 backslash character has to be really the last character before the
9291 newline and it has not been prefixed by another (escaping) backslash.

9297 *) To deal with modules being compiled and [dynamically] linked
9298 at a different time from the core, the SERVER_VERSION and
9299 SERVER_BUILT symbols have been abstracted through the new
9300 API routines apapi_get_server_version() and apapi_get_server_built().
9303 *) WIN32: Preserve trailing slash in canonical path (and hence
9304 in PATH_INFO). [Paul Sutton, Ben Laurie]
9306 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
9307 depending on the rev of Solaris and what mixture of modules
9308 are in use. So it has been disabled, and Solaris is back to
9309 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9310 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9311 up static content only servers. Or it may fail unpredictably.
9312 [Dean Gaudet] PR#1779, 1854, 1904
9314 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9317 *) API: Rewrite of absoluteURI handling, and in particular how
9318 absoluteURIs match vhosts. Unless a request is a proxy request, a
9319 "http://host" url is treated as if a similar "Host:" header had been
9320 supplied. This change was made to support future HTTP/1.x protocols
9321 which may require clients to send absoluteURIs for all requests.
9323 In order to achieve this change subtle changes were made to the API. In a
9324 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9325 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9326 by the core, modules must set it during the post_read_request or
9327 translate_names phase.
9329 Plus changes to the virtualhost test suite for absoluteURI testing.
9331 This fixes several bugs with the proxy proxying requests to vhosts
9332 managed by the same httpd.
9335 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
9336 code from mod_rewrite. The vhost matching is now performed by a
9337 globally available function matches_request_vhost(). [Dean Gaudet]
9339 *) Reduce memory usage, and speed up ServerAlias support. As a
9340 side-effect users can list multiple ServerAlias directives
9341 and they're all considered.

9348 *) Make \\ behave as expected. [Ronald.Tschalaer@psi.ch]
9350 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
9351 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
9353 *) API: A new source module main/util_uri.c; It contains a routine
9354 parse_uri_components() and friends which breaks a URI into its component
9355 parts. These parts are stored in a uri_components structure called
9356 parsed_uri within each request_rec, and are available to all modules.
9357 Additionally, an unparse routine is supplied which re-assembles the URI
9358 components back to an URI, optionally hiding the username:password@ part
9359 from ftp proxy requests, and other useful routines. Within the structure,
9360 you find on a ready-for-use basis:
9361 scheme; /* scheme ("http"/"ftp"/...) */
9362 hostinfo; /* combined [user[:password]@]host[:port] */
9363 user; /* user name, as in http://user:passwd@host:port/ */
9364 password; /* password, as in http://user:passwd@host:port/ */
9365 hostname; /* hostname from URI (or from Host: header) */
9366 port_str; /* port string (integer representation is in "port") */
9367 path; /* the request path (or "/" if only scheme://host was given) */
9368 query; /* Everything after a '?' in the path, if present */
9369 fragment; /* Trailing "#fragment" string, if present */
9370 This is meant to serve as the platform for *BIG* savings in
9371 code complexity for the proxy module (and maybe the vhost logic).
9374 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
9375 ${map:key}) available for all location where a string is created in
9376 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
9377 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
9378 possible expansions are consequently usable at all string creation
9379 locations. [Ralf S. Engelschall]
9381 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
9382 and not 1) and the per-virtual-server merging of directives. Now all
9383 directives except `RewriteEngine' and `RewriteOption' are either
9384 completely overridden (default) or completely inherited (when
9385 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

9388 defined but disabled (`RewriteEngine off') in per-server context.

9391 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
9392 server to bind to port 0 rather than 80. [Dean Gaudet]
9394 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
9395 (like SunOS and FreeBSD) which don't accept the locking of pipes
9396 directly. A new directive RewriteLock is introduced which can be used to
9397 setup a separate locking file which then is used for synchronization.

9413 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
9415 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
9416 type but with a special post-processing for the looked-up value: It
9417 parses it into alternatives according to `|' chars and then only one
9418 particular alternative is chosen randomly (this is an essential
9419 functionality needed for balancing between backend-servers when using
9420 Apache as a Reverse Proxy. The looked up value here is a list of
9421 servers). Second, `int' with the built-in maps named `tolower' and
9422 `toupper' which can be used to map URL parts to a fixed case (this is an
9423 essential feature to fix the case of server names when doing mass
9424 virtual-hosting with the help of mod_rewrite instead of using
9425 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
9426 Jay Soffian <jay@cimedia.com>] PR#1631
9428 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
9429 This directive lets Apache adjust the URL in Location-headers on HTTP
9430 redirect responses sent by the remote server. This way the virtually
9431 mapped area is no longer left on redirects and thus by-passed which is
9432 especially essential when running Apache as a reverse proxy.

9547 now ignores a leading x- when comparing encodings. It also
9548 preserves the encoding the client requests (for example if
9549 it requests x-gzip, then Apache will respond with x-gzip
9550 in the Content-Encoding header).

9580 *) Yet another rearrangement of the source tree.. now all the common
9581 header files are in the src/include directory. The -Imain -Iap
9582 references in Makefiles have been changed to the simpler -Iinclude
9583 instead. In addition to simplifying the build a little bit, this
9584 also makes it clear when a module is referencing something in a
9585 other than kosher manner (e.g., the proxy including mod_mime.h).
9586 Module-private header files (the proxy, mod_mime, the regex library,
9587 and mod_rewrite) have not been moved to src/include; nor have

9600 server setting inside vhosts (only an issue when you have no
9601 <Directory> or other section containing an Options that affects
9602 a request). Options +foo or -foo in the main_server wouldn't

9617 *) mod_unique_id was erroneously generating a second unique id when
9618 an internal redirect occured. Such redirects occur, for example,
9619 when processing a DirectoryIndex match. [Dean Gaudet]
9621 *) API: table_add, table_merge, and table_set include implicit pstrdup()
9622 of the key and value. But in many cases this is not required
9623 because the key/value is a constant, or the value has been built
9624 by pstrcat() or other similar means. New routines table_addn,
9625 table_mergen, and table_setn have been added to the API, these
9626 routines do not pstrdup() their arguments. The core code and
9627 standard modules were changed to take advantage of these routines.
9628 The resulting server is up to 20% faster in some situations.
9630 Note that it is easy to get code subtly wrong if you pass a key/value
9631 which is in a pool other than the pool of the table. The only
9632 safe thing to do is to pass key/values which are in the pool of
9633 the table, or in one of the ancestors of the pool of the table.
9634 i.e. if the table is part of a subrequest, a value from the main
9635 request's pool is OK since the subrequest pool is a sub_pool of the
9636 main request's pool (and therefore has a lifespan at most as long as
9637 the main pool). There is debugging code which can detect improper
9638 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
9639 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
9641 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
9642 which don't exist on disk more gracefully; handles vhosts properly.
9643 Update documentation to reflect the code -- if there's no
9644 MimeMagicFile directive then the module is not enabled.
9647 *) PORT: Some older *nix dialects cannot automatically start scripts
9648 which begin with a #! interpreter line (the shell starts the scripts
9649 appropriately on these platforms). Apache now supports starting of
9650 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.

9654 *) API: "typedef array_header table" removed from alloc.h, folks should
9655 have been writing to use table as if it were an opaque type, but even
9656 some standard modules got this wrong. By changing the definition
9657 to "typedef struct table table" module authors will receive compile
9658 time warnings that they're doing the wrong thing. This change
9659 facilitates future changes with more sophisticated table
9660 structures. Specifically, module authors should be using table_elts()
9661 to get access to an array_header * for the table. [Dean Gaudet]
9663 *) API: Renamed new_connection() to avoid namespace collision with LDAP
9664 library routines. [Ken Coar, Rasmus Lerdorf]

9669 *) For clarity the following compile time definition was changed:
9671 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
9673 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
9674 and not be a general notice that the OS has mmap(). Now the
9675 HAVE_MMAP/SHMGET #defines strictly are informational that the
9676 OS has that method of shared memory; the type to use for
9677 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
9678 and USE_SHMGET_SCOREBOARD). This allows outside modules to
9679 determine if shared memory is available and allows Apache
9680 to determine the best method to use for the scoreboard.

9694 as a POST problem with MSIE 4.0, typically against pages which are
9695 authenticated. [Roy Fielding] PR#1399
9697 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
9698 header will be passed to CGIs. This is generally a security hole, so
9699 it's not a default. [Marc Slemko] PR#549

9706 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
9708 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
9709 The choice of flock vs. fcntl was made based on timings which showed that
9710 even on non-NFS, non-exported filesystems fcntl() was an order of
9711 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
9712 that single socket users will see no difference. [Dean Gaudet] PR#467
9714 *) "File does not exist" error message was erroneously including the
9715 errno. [Marc Slemko]
9717 *) Improve the warning message generated when a client drops the
9718 connection (hits stop button, etc.) during a send. [Roy Fielding]
9720 *) Defining GPROF will disable profiling in the parent and enable it
9721 in the children. If you're profiling under Linux this is pretty much
9722 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
9724 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
9727 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
9728 gcc functionality. Work around it.
9729 [Keith Severson <keith@sssd.navy.mil>] PR#1613
9731 *) Some linkers complain when .o files contain no functions.
9732 [Keith Severson <keith@sssd.navy.mil>] PR#1614
9734 *) Some const declarations in mod_imap.c that were added for debugging
9735 purposes caused some compilers heartburn without adding any
9736 significant value, so they've been removed. [Ken Coar]
9738 *) The src/main/*.h header files have had #ifndef wrappers added to
9739 insulate them against duplicate calls if they get included through
9740 multiple paths (e.g., in .c files as well as other .h files).
9743 *) The libap routines now have a header file for their prototypes,
9744 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
9746 *) mod_autoindex with a plaintext header file would emit the <PRE>
9747 start-tag before the HTML preamble, rather than after the preamble
9748 but before the header file contents. [John Van Essen <jve@gamers.org>]
9751 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
9752 only an issue on systems without a MAXDNAME define or where
9753 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
9755 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
9756 is used to read various types of files such as htaccess and
9757 htpasswd files. [Marc Slemko]
9759 *) SECURITY: Ensure that the buffer returned by ht_time is always
9760 properly null terminated. [Marc Slemko]
9762 *) The "Connection" header could be sent back with multiple "close"
9763 tokens. Not an error, but a waste.
9764 [Ronald.Tschalaer@psi.ch] PR#1683
9766 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
9767 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
9769 *) "basic" auth needs a case-insensitive comparison.
9770 [Ronald.Tschalaer@psi.ch] PR#1666
9772 *) For maximum portability, the environment passed to CGIs should
9773 only contain variables whose names match the regex
9774 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
9775 underscores over any character outside the regex. This
9776 affects HTTP_* variables, in a way that should be backward
9777 compatible for all the standard headers; and affects variables
9778 set with SetEnv/BrowserMatch and similar directives.
9781 *) mod_speling returned incorrect HREF's when an ambigous match

9817 *) SECURITY: Numerous changes to mod_imap in a general cleanup
9818 including fixing a possible buffer overflow. [Dean Gaudet]

9821 (connections are not dropped). Code can handle graceful restarts
9822 (but there is as yet no way to signal this to Apache). Various
9823 other cleanups. [Paul Sutton]
9825 *) The aplog_error changes specific to 1.3 introduced a buffer
9826 overrun in the (now legacy) log_printf function. Fixed.
9829 *) mod_digest didn't properly deal with proxy authentication. It
9830 also lacked a case-insensitive comparision of the "Digest"

9864 *) send_fd_length() did not calculate total_bytes_sent properly.
9865 [Ben Reser <breser@regnow.com>] PR#1366
9867 *) The bputc() macro was not properly integrated with the chunking
9868 code; in many cases modules using bputc() could cause completely
9869 bogus chunked output. (Typically this will show up as problems
9870 with Internet Explorer 4.0 reading a page, but other browsers
9871 having no problem.) [Dean Gaudet]
9873 *) Create LARGE_WRITE_THRESHOLD define which determines how many
9874 bytes have to be supplied to bwrite() before it will consider
9875 doing a writev() to assemble multiple buffers in one system
9876 call. This is critical for modules such as mod_include,
9877 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
9878 strings in some cases. The result would be extra effort
9879 setting up writev(), and in many cases extra effort building
9880 chunks. The default is 31, it can be overriden at compile
9883 *) Move the gid switching code into the child so that log files

9990 This turns out to be a bug in Winsock - select() doesn't always

9993 *) Directives owned by http_core can now use the new check_cmd_context()
9994 routine to ensure that they're not being used within a container
9995 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
9997 *) PORT: Recent changes made it necessary to add explicit prototype
9998 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
10000 *) It was necessary to distinguish between resources which are
10001 allocated in the parent, for cleanup in the parent, and resources
10002 which are allocated in each child, for cleanup in each child.
10003 A new pool was created which is passed to the module child_init
10004 and child_exit functions; modules are free to register per-child
10005 cleanups there. This fixes a bug with reliable piped logs.
10008 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
10009 unless it was also doing FancyIndexes, but it displayed the
10010 HeaderName file at the top under all circumstances. It now shows
10011 the ReadmeName file for simple indices, too, as it should.
10014 *) http_core was mmap()ing even in cases where it wasn't going to
10015 read the file. [Ben Hyde <bhyde@gensym.com>]
10017 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
10018 Now the rewriting engine (the heart of mod_rewrite) is organized more
10019 straight-forward, first time well documented and reduced to the really
10020 essential parts. All redundant cases were stripped off and processing now
10021 is the same for both per-server and per-directory context with only a
10022 minimum difference (the prefix stripping in per-dir context). As a
10023 side-effect some subtle restrictions and two recently discovered problems
10024 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
10025 context and restrictions on the substitution URL on redirects.
10026 Additionally some minor source cleanups were done.

10183 *) TestCompile was not passing $LIBS [Dean Gaudet]
10185 *) Makefile.tmpl was not using $CFLAGS in the link phase.
10188 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
10189 rudimentary memory debugger which can be used on live servers with
10190 low impact -- it sets all allocated and freed memory bytes to 0xa5.
10191 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
10192 and free() for each object. This is far more expensive and should
10193 only be used for testing with tools such as Electric Fence and
10194 Purify. See main/alloc.c for more details. [Dean Gaudet]

10201 From a given ip:port, regardless what the Host: header is, you can
10202 only reach the vhosts defined on that ip:port. The precedence of
10203 vhosts was reversed to match other precedences in the config --
10204 the earlier vhosts override the later vhosts. All vhost matching was
10205 moved into http_vhost.[ch]. [Dean Gaudet]

10218 received. [Marc Slemko, Dean Gaudet]
10220 *) PORT: Support for Atari MINT.
10221 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
10223 *) When booting, apache will now detach itself from stdin, stdout,
10224 and stderr. stderr will not be detached until after the config
10225 files have been read so you will be able to see initial error
10226 messages. After that all errors are logged in the error_log.
10227 This makes it more convenient to start apache via rsh, ssh,
10228 or crontabs. [Dean Gaudet] PR#523
10230 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10231 Also removed the auto-generated link to www.apache.org that was the
10232 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10234 *) send_fb would not detect aborted connections in some situations.
10237 *) mod_include would use uninitialized data when parsing certain
10238 expressions involving && and ||. [Brian Slesinsky] PR#1139
10240 *) mod_imap should only handle GET methods. [Jay Bloodworth]
10242 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10244 *) mod_autoindex improperly counted &escapes; as more than one
10245 character in the description. It also improperly truncated
10246 descriptions that were exactly the maximum length.
10249 *) RedirectMatch was not properly escaping the result (PR#1155). Also
10250 "RedirectMatch /advertiser/(.*) $1" is now permitted.
10253 *) mod_include now uses symbolic names to check for request success
10254 and return HTTP errors, and correctly handles all types of
10255 redirections (previously it only did temporary redirect correctly).
10256 [Ken Coar, Roy Fielding]
10258 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10259 r->filename. Since those two are meant to be in sync with each other
10260 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
10262 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
10263 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
10265 *) Inetd mode (which is buggy) uses timeouts without having setup the
10266 jmpbuffer. [Dean Gaudet] PR#1064
10268 *) Work around problem under Linux where a child will start looping
10269 reporting a select error over and over.
10270 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
10272 *) Fixed error in proxy_util.c when looping through multiple host IP
10273 addresses. [Lars Eilebrecht] PR#974
10275 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10276 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10277 bytes before writing, but it will never split a log entry across a
10278 buffer boundary. [Dean Gaudet]
10280 *) API: the short_score record has been split into two pieces, one which
10281 the parent writes on, and one which the child writes on. As part of
10282 this change the get_scoreboard_info() function was removed, and
10283 scoreboard_image was exported. This change fixes a race condition
10284 in file based scoreboard systems, and speeds up changes involving the
10285 scoreboard in earlier 1.3 development. [Dean Gaudet]
10287 *) API: New register_other_child() API (see http_main.h) which allows
10288 modules to register children with the parent for maintenance. It
10289 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10291 *) API: New piped_log API (see http_log.h) which implements piped logs,
10292 and will use register_other_child to implement reliable piped logs
10293 when it is available. The reliable piped logs part can be disabled
10294 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10295 logs is only available on Unix. [Dean Gaudet]
10297 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10298 meets_conditions(). This allows conditional HTTP selection to be
10299 handled separately from the storing of the header fields, and provides
10300 the ability for CGIs to set their own ETags for conditional checking.
10301 [Ken Coar, Roy Fielding] PR#895
10303 *) Changes to mod_log_config to allow naming of format strings.
10304 Format nicknames are defined with "LogFormat fmt nickname", and can
10305 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
10308 *) New module, "mod_speling", which can help find files even when
10309 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
10311 *) API: New function child_terminate() triggers the child process to
10312 exit, while allowing the child finish what it needs to for the
10313 current request first.
10314 [Doug MacEachern, Alexei Kosut]
10316 *) Windows now defaults to using full status reports with mod_status.
10317 [Alexei Kosut] PR #1094
10319 *) *Really* disable all mod_rewrite operations if the engine is off.
10320 Some things (like RewriteMaps) were checked/performed even if they
10321 weren't supposed to be. [Ken Coar] PR #991
10323 *) Implement a new timer scheme which eliminates the need to call alarm() all
10324 the time. Instead a counter in the scoreboard for each child is used to
10325 show when the child has made forward progress. The parent samples this
10326 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10327 progress has been made in the timeout period. This reduces the static
10328 request best-case syscall count to 22 from 29. This scheme is only
10329 used by systems with memory-based scoreboards. [Dean Gaudet]
10331 *) The proxy now properly handles CONNECT requests which are sent
10332 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10334 *) A script called apachectl has been added to the support
10335 directory. This script allows you to do things such as
10336 "apachectl start" and "apachectl restart" from the command
10337 line. [Marc Slemko]
10339 *) Modules and core routines are now put into libraries, which
10340 simplifies the link line tremendously (among other advantages).
10343 *) Some of the MD5 names defined in Apache have been renamed to have
10344 an `ap_' prefix to avoid conflicts with routines supplied by
10345 external libraries. [Ken Coar]
10347 *) Removal of mod_auth_msql.c from the distribution. There are many
10348 other options for databases today. Rather than offer one option,
10349 offer none at this time. mod_auth_msql and other SQL database
10350 authentication modules can be found at the Apache Module Registry.
10351 http://modules.apache.org/ It would be nice to offer a generic
10352 mod_auth_sql option in the near future.
10354 *) PORT: BeOS support added [Alexei Kosut]
10356 *) Configure no longer accepts the -make option, since it creates
10357 Makefile on the fly based on Makefile.tmpl and Configuration.
10359 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
10360 of forcibly killing off all its processes and exiting without
10361 cleaning up. [Alexei Kosut]
10363 *) API: A new field in the request_rec, r->mtime, has been added to
10364 avoid gratuitous parsing of date strings. It is intended to hold
10365 the last-modified date of the resource (if applicable). An
10366 update_mtime() routine has also been added to advance it if
10367 appropriate. [Roy Fielding, Ken Coar]
10369 *) SECURITY: If a htaccess file can not be read due to bad permissions,
10370 deny access to the directory with a HTTP_FORBIDDEN. The previous
10371 behavior was to ignore the htaccess file if it could not be read.
10372 This change may make some setups with unreadable htaccess files
10373 stop working. [Marc Slemko] PR#817
10375 *) Add aplog_error() providing a mechanism to define levels of
10376 verbosity to the server error logging. This addition also provides
10377 the ability to log errors using syslogd. Error logging is configurable
10378 on a per-server basis using the LogLevel directive. Conversion
10379 of log_*() in progress. [Randy Terbush]
10381 *) Further enhance aplog_error() to not log filename, line number, and
10382 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
10384 *) WIN32: Canonicalise filenames under Win32. Short filenames are
10385 converted to long ones. Backslashes are converted to forward
10386 slashes. Case is converted to lower. Parts of URLs that do not
10387 correspond to files are left completely alone. [Ben Laurie]
10389 *) PORT: 2 new OSs added to the list of ports:
10390 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
10391 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
10393 *) Add the server version (SERVER_VERSION macro) to the "server
10394 configured and running" entry in the error_log. Also build an
10395 object file at link-time that contains the current time
10396 (SERVER_BUILT global const char[]), and include that in the
10397 message. [Ken Coar]
10399 *) Set r->headers_out when sending responses from the proxy.
10400 This fixes things such as the logging of headers sent from
10401 the proxy. [Marc Slemko] PR#659
10403 *) support/httpd_monitor is no longer distributed because the
10404 scoreboard should not be file based if at all possible. Use
10405 mod_status to see current server snapshot.
10407 *) (set_file_slot): New function, allowing auth directives to be
10408 independent of the server root, so the server documents can be
10409 moved to a different directory or machine more easily.
10410 [David J. MacKenzie]
10412 *) If no TransferLog is given explicitly, decline
10413 to log. This supports coexistence with other logging modules,
10414 such as the custom one that UUNET uses. [David J. MacKenzie]
10416 *) Check for titles in server-parsed HTML files.
10417 Ignore leading newlines and returns in titles. The old behavior
10418 of replacing a newline after <title> with a space causes the
10419 title to be misaligned in the listing. [David J. MacKenzie]
10421 *) Change mod_cern_meta to be configurable on a per-directory basis.
10422 [David J. MacKenzie]
10424 *) Add 'Include' directive to allow inclusion of configuration
10425 files within configuration files. [Randy Terbush]
10427 *) Proxy errors on connect() are logged to the error_log (nothing
10428 new); now they include the IP address and port that failed
10429 (*that's* new). [Ken Coar, Marc Slemko] PR#352
10431 *) Various architectures now define USE_MMAP_FILES which causes
10432 the server to use mmap() for static files. There are two
10433 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
10434 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
10435 number of bytes written in one cycle from a single mmap()d object,
10436 default 32768). [Dean Gaudet]
10438 *) API: Added post_read_request API phase which is run right after reading
10439 the request from a client, or right after an internal redirect. It is
10440 useful for modules setting environment variables that depend only on
10441 the headers/contents of the request. It does not run during subrequests
10442 because subrequests inherit pretty much everything from the main
10443 request. [Dean Gaudet]
10445 *) Added mod_unique_id which is used to generate a unique identifier for
10446 each hit, available in the environment variable UNIQUE_ID.
10449 *) init_modules is now called after the error logs have been opened. This
10450 allows modules to emit information messages into the error logs.
10453 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
10454 information for case where proxy module is not available. [Marc Slemko]
10456 *) PORT: Apache has need for mutexes to serialize its children around
10457 accept. In prior versions either fcntl file locking or flock file
10458 locking were used. The method is chosen by the definition of
10459 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
10460 and FLOCK for flock(). New options have been added:
10461 - SYSVSEM to use System V style semaphores
10462 - PTHREAD to use POSIX threads (appears to work on Solaris only)
10463 - USLOCK to use IRIX uslock
10464 Based on timing various techniques, the following changes were made
10466 - Linux 2.x uses flock instead of fcntl
10467 - Solaris 2.x uses pthreads
10468 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
10469 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
10470 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
10471 Martijn Koster <m.koster@pobox.com>]
10473 *) PORT: The semantics of accept/select make it very desirable to use
10474 mutexes to serialize accept when multiple Listens are in use. But
10475 in the case where only a single socket is open it is sometimes
10476 redundant to serialize accept(). Not all unixes do a good job with
10477 potentially dozens of children blocked on accept() on the same
10478 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
10479 the server will avoid serialization when listening on only one socket,
10480 and use serialization when listening on multiple sockets.
10481 [Dean Gaudet] PR#467
10483 *) Configure changes: TestLib replaced by TestCompile, which has
10484 some additional capability (such as doing a sanity check of
10485 the compiler and flags selected); the version of Solaris is now
10486 available via the #define value of SOLARIS2; IRIX n32bit libs
10487 now supported and selectable by new Configuration Rule: IRIXN32;
10488 We no longer default to -O2 optimization. [Jim Jagielski]
10490 *) Updated Configure: Configuration now uses AddModule to specify
10491 module source or binary file location, relative to src directory.
10492 Modules can be dropped into modules/extra, or in their own
10493 directory, and modules can come with a Makefile or Configure can
10494 create one. Modules can add compiler or library information to
10495 generated Makefiles. [Paul Sutton]
10497 *) Source core re-organisation: distributed modules are now in
10498 modules/standard. All other source code is in main. OS-specific
10499 code is in os/{unix,emx,win32} directories. [Paul Sutton]
10501 *) mod_browser has been removed, since it's replaced by mod_setenvif.
10504 *) Fix another long-standing bug in sub_req_lookup_file where it would
10505 happily skip past access checks on subdirectories looked up with
10506 relative paths. (It's used by mod_dir, mod_negotiation,
10507 and mod_include.) [Dean Gaudet]
10509 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
10510 N is the number of <Directory> sections, and M is the number of
10511 components in the filename of an object.
10513 To achieve this optimization the following config changes were made:
10514 - Wildcards (* and ?, not the regex forms) in <Directory>s,
10515 <Files>s, and <Location>s now treat a slash as a special
10516 character. For example "/home/*/public_html" previously would
10517 match "/home/a/andrew/public_html", now it only matches things
10518 like "/home/bob/public_html". This mimics /bin/sh behaviour.
10519 - It's possible now to use [] wildcarding in <Directory>, <Files>
10521 - Regex <Directory>s are applied after all non-regex <Directory>s.
10525 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
10526 and corrupted paths. [Dean Gaudet]
10528 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
10529 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
10530 be accessed now via backreferences $1..$9 in RewriteConds test-against
10531 strings in addition to RewriteRules subst string. Second the grouped
10532 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
10533 via backreferences %1..%9 both in following RewriteCond test-against
10534 strings and RewriteRules subst string. This provides maximum flexibility
10535 through the use of backreferences.
10536 Additionally the rewriting engine was cleaned up by putting common
10537 code to the new expand_backrefs_inbuffer() function.
10538 [Ralf S. Engelschall]
10540 *) When merging the main server's <Directory> and <Location> sections into
10541 a vhost, put the main server's first and the vhost's second. Otherwise
10542 the vhost can't override the main server. [Dean Gaudet] PR#717
10544 *) The <Directory> code would merge and re-merge the same section after
10545 a match was found, possibly causing problems with some modules.
10548 *) ip-based vhosts are stored and queried using a hashing function, which
10549 has been shown to improve performance on servers with many ip-vhosts.
10550 Some other changes had to be made to accommodate this:
10551 - the * address for vhosts now behaves like _default_
10552 - the matching process now is:
10553 - match an ip-vhost directly via hash (possibly matches main
10555 - if that fails, just pretend it matched the main server
10556 - if so far only the main server has been matched, perform
10557 name-based lookups (ServerName, ServerAlias, ServerPath)
10558 *only on name-based vhosts*
10559 - if they fail, look for _default_ vhosts
10560 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
10562 *) dbmmanage overhaul:
10563 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
10564 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
10565 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
10566 - provide better seed for rand
10567 - prompt for password as per getpass(3) (turn off echo, read from
10569 - use "newstyle" crypt based on $Config{osname} ($^O)
10570 - will not add a user if already in database, use new `update' command
10572 - added `check' command to check a users' password
10573 - added `import' command to convert existing password text-files or
10574 dbm files exported with `view'
10575 - more descriptive usage, general cleanup, 'use strict' clean, etc.
10578 *) Added psocket() which is a pool form of socket(), various places within
10579 the proxy weren't properly blocking alarms while registering the cleanup
10580 for its sockets. bclose() now uses pclose() and pclosesocket(). There
10581 was a bug where the client socket was being close()d twice due a still
10582 registered cleanup. [Dean Gaudet]
10584 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
10587 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
10588 [Jason Venner <jason@idiom.com>] PR#667
10590 *) Enable ``=""'' for RewriteCond directives to match against
10591 the empty string. This is the preferred way instead of ``^$''.
10592 [Ralf S. Engelschall]
10594 *) Fixed an infinite loop in mod_imap for references above the server root
10595 [Dean Gaudet] PR#748
10597 *) mod_proxy now has a ReceiveBufferSize directive, similar to
10598 SendBufferSize, so that the TCP window can be set appropriately
10599 for LFNs. [Phillip A. Prindeville]
10601 *) mod_browser has been replaced by the more general mod_setenvif
10602 (courtesy of Paul Sutton). BrowserMatch* directives are still
10603 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
10604 UnSetEnvIfZero directives. [Ken Coar]
10606 *) "HostnameLookups double" forces double-reverse DNS to succeed in
10607 order for remote_host to be set (for logging, or for the env var
10608 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
10611 *) mod_access overhaul:
10612 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
10613 and cidr syntax (i.e. 10.1.0.0/16). PR#762
10614 - Critical path was sped up by pre-computing a few things at config time.
10615 - The undocumented syntax "allow user-agents" was removed,
10616 the replacement is "allow from env=foobar" combined with mod_browser.
10617 - When used with hostnames it now forces a double-reverse lookup
10618 no matter what the directory settings are. This double-reverse
10619 doesn't affect any of the other routines that use the remote
10620 hostname. In particular it's still passed to CGIs and the log
10621 without the double-reverse check. Related PR#860.
10624 *) When a large bwrite() occurs (larger than the internal buffer size),
10625 while there is already something in the buffer, apache will combine
10626 the large write and the buffer into a single writev(). (This is
10627 in anticipation of using mmap() for reading files.)
10630 *) In obscure cases where a partial socket write occurred while chunking,
10631 Apache would omit the chunk header/footer on the next block. Cleaned
10632 up other bugs/inconsistencies in error conditions in buff.c. Fixed
10633 a bug where a long pause in DNS lookups could cause the last packet
10634 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
10636 *) API: Added child_exit function to module structure. This is called
10637 once per "heavy-weight process" just before a server child exit()'s
10638 e.g. when max_requests_per_child is reached, etc.
10639 [Doug MacEachern, Dean Gaudet]
10641 *) mod_include cleanup showed that handle_else was being used to handle
10642 endif. It didn't cause problems, but it was cleaned up too.
10645 *) mod_cern_meta would attempt to find meta files for the directory itself
10646 in some cases, but not in others. It now avoids it in all cases.
10649 *) mod_mime_magic would core dump if there was a decompression error.
10650 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
10652 *) PORT: some variants of DGUX require -lsocket -lnsl
10653 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
10655 *) mod_autoindex now allows sorting of FancyIndexed directory listings
10656 by the various fields (name, size, et cetera), either in ascending
10657 or descending order. Just click on the column header. [Ken Coar]
10659 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
10660 CPUs like the Alpha. Apache still stores ints in pointers, but that's
10661 the relatively safe direction. [Dean Gaudet] PR#344
10663 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
10664 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
10666 *) child_main avoids an unneeded call to select() when there is only one
10667 listening socket. [Dean Gaudet]
10669 *) In the event that the server is starved for idle servers it will
10670 spawn 1, then 2, then 4, ..., then 32 servers each second,
10671 doubling each second. It'll also give a warning in the errorlog
10672 since the most common reason for this is a poor StartServers
10673 setting. The define MAX_SPAWN_RATE can be used to raise/lower
10674 the maximum. [Dean Gaudet]
10676 *) Apache now provides an effectively unbuffered connection for
10677 CGI scripts. This means that data will be sent to the client
10678 as soon as the CGI pauses or stops output; previously, Apache would
10679 buffer the output up to a fixed buffer size before sending, which
10680 could result in the user viewing an empty page until the CGI finished
10681 or output a complete buffer. It is no longer necessary to use an
10682 "nph-" CGI to get unbuffered output. Given that most CGIs are written
10683 in a language that by default does buffering (e.g. perl) this
10684 shouldn't have a detrimental effect on performance.
10686 "nph-" CGIs, which formerly provided a direct socket to the client
10687 without any server post-processing, were not fully compatible with
10688 HTTP/1.1 or SSL support. As such they would have had to implement
10689 the transport details, such as encryption or chunking, in order
10690 to work properly in certain situations. Now, the only difference
10691 between nph and non-nph scripts is "non-parsed headers".
10692 [Dean Gaudet, Sameer Parekh, Roy Fielding]
10694 *) If a BUFF is switched from buffered to unbuffered reading the first
10695 bread() will return whatever remained in the buffer prior to the
10696 switch. [Dean Gaudet]
10698 Changes with Apache 1.3a1
10700 *) Added another Configure helper script: TestLib. It determines
10701 if a specified library exists. [Jim Jagielski]
10703 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
10704 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
10707 *) PORT: Some architectures use size_t for various lengths in network
10708 functions such as accept(), and getsockname(). The definition
10709 NET_SIZE_T is used to control this. [Dean Gaudet]
10711 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
10712 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
10713 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
10715 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
10716 [Igor N Kovalenko <infoh@mail.wplus.net>]
10718 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
10719 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
10720 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

10742 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
10744 *) Added NoProxy directive to avoid using ProxyRemote for selected
10745 addresses. Added ProxyDomain directive to cause unqualified
10746 names to be qualified by redirection.
10747 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
10749 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
10750 header to the remote host in the proxy. [Sameer Parekh and
10753 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
10754 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
10755 URLs, fixed rewritelog(), fixed forced response code handling on
10756 redirects from within .htaccess files, disabled pipe locking under
10757 braindead SunOS 4.1.x, allow env variables to be set even on rules with
10758 no substitution, bugfixed situations where HostnameLookups is off, made
10759 mod_rewrite more thread-safe for NT port and fixed problem when creating
10760 an empty query string via "xxx?".
10761 This update also removes the copyright of Ralf S. Engelschall,
10762 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
10763 exclusively copyrighted by the Apache Group now. This happened because
10764 the author now has gifted mod_rewrite exclusively to the Apache Group and
10765 no longer maintains an external version.
10766 [Ralf S. Engelschall]
10768 *) API: Added child_init function to module structure. This is called
10769 once per "heavy-weight process" before any requests are handled.
10770 See http_config.h for more details. [Dean Gaudet]
10772 *) Anonymous_LogEmail was logging on each subrequest.
10773 [Dean Gaudet] PR#421, 868
10775 *) API: Added is_initial_req() which tests if the request being
10776 processed is the initial request, or a subrequest.
10779 *) Extended SSI (mod_include) now handles additional relops for
10780 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
10782 *) Configure fixed to correctly propagate user-selected options and
10783 settings (such as CC and OPTIM) to Makefiles other than
10784 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
10786 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
10787 directory indices to start with the contents of the HeaderName file
10788 if there is one. If there isn't one, the behaviour is unchanged.
10789 [Ken Coar, Roy Fielding, Andrey A. Chernov]
10791 *) WIN32: Modules can now be dynamically loaded DLLs using the
10792 LoadModule/LoadFile directives. Note that module DLLs must be
10793 compiled with the multithreaded DLL version of the runtime library.
10794 [Alexei Kosut and Ben Laurie]
10796 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
10797 This allows the admin to completely remove automatic indexing
10798 from the server, while still supporting the basic functions of
10799 trailing-slash redirects and DirectoryIndex files. Note that if
10800 you're carrying over an old Configuration file and you use directory
10801 indexing then you'll want to add:
10803 Module autoindex_module mod_autoindex.o
10805 before mod_dir in your Configuration. [Dean Gaudet]
10807 *) popendir/pclosedir created to properly protect directory scanning.
10808 [Dean Gaudet] PR#525
10810 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
10811 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
10812 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
10815 *) The AccessFileName directive can now take more than one filename.
10816 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
10818 *) The new mod_mime_magic can be used to "magically" determine the type
10819 of a file if the extension is unknown. Based on the unix file(1)
10820 command. [Ian Kluft <ikluft@cisco.com>]
10822 *) We now determine and display the time spent processing a
10823 request if desired. [Jim Jagielski]
10825 *) mod_status: PID field of "dead" child slots no longer displays
10826 main httpd process's PID. [Jim Jagielski]
10828 *) Makefile.nt added - to build all the bits from the command line:
10829 nmake -f Makefile.nt
10830 Doesn't yet work properly. [Ben Laurie]
10832 *) Default text of 404 error is now "Not Found" rather than the
10833 potentially misleading "File Not Found". [Ken Coar]
10835 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
10836 for the net if we require people that actually need this data to
10837 enable it. [Linus Torvalds]
10839 *) directory_walk() is an expensive function, keep a little more state to
10840 avoid needless string counting. Add two new functions make_dirstr_parent
10841 and make_dirstr_prefix which replace all existing uses of make_dirstr.
10842 The new functions are a little less general than make_dirstr, but
10843 work more efficiently (less memory, less string counting).
10846 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
10847 to LDFLAGS) to avoid complications with lex rules in make files.
10848 [Dean Gaudet] PR#372
10850 *) run_method optimized to avoid needless scanning over NULLs in the
10851 module list. [Dean Gaudet]
10853 *) Revamp of (unix) scoreboard management code such that it avoids
10854 unnecessary traversals of the scoreboard on each hit. This is
10855 particularly important for high volume sites with a large
10856 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
10857 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
10858 httpd.h. [Dean Gaudet]
10860 *) In configurations using multiple Listen statements it was possible for
10861 busy sockets to starve other sockets of service. [Dean Gaudet]
10863 *) Added hook so standalone_main can be replaced at compile time
10864 (define STANDALONE_MAIN)
10867 *) Lowest-level read/write functions in buff.c will be replaced with
10868 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
10869 compile time. The default sfio discipline will behave as apache
10870 would without sfio compiled in.
10873 *) Enhance UserDir directive (mod_userdir) to accept a list of
10874 usernames for the 'disable' keyword, and add 'enable user...' to
10875 selectively *en*able userdirs if they're globally disabled.
10878 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
10879 will work with Netscape dbm files. (dbmmanage will probably not
10880 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
10882 *) Add a ListenBacklog directive to control the backlog parameter
10883 passed to listen(). Also change the default to 511 from 512.
10886 *) API: A new handler response DONE which informs apache that the
10887 request has been handled and it can finish off quickly, similar to
10888 how it handles errors. [Rob Hartill]
10890 *) Turn off chunked encoding after sending terminating chunk/footer
10891 so that we can't do it twice by accident. [Roy Fielding]
10893 *) mod_expire also issues Cache-Control: max-age headers.
10896 *) API: Added kill_only_once option for free_proc_chain so that it won't
10897 aggressively try to kill off specific children. For fastcgi.
10898 [Stanley Gambarin <gambarin@OpenMarket.com>]
10900 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
10902 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
10903 When used together, these cause mod_dir to emit HEIGHT and WIDTH
10904 attributes in the FancyIndexing IMG tags. [Ken Coar]
10906 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
10908 *) PORT: Added Windows NT support

10911 Changes with Apache 1.2.6
10913 *) mod_include when using XBitHack Full would send ETags in addition to
10914 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
10915 [Dean Gaudet] PR#1133
10917 *) SECURITY: When a client connects to a particular port/addr, and
10918 gives a Host: header ensure that the virtual host requested can
10919 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
10921 *) Support virtual hosts with wildcard port and/or multiple ports
10922 properly. [Ed Korthof <ed@organic.com>]
10924 *) Fixed some case-sensitivity issues according to RFC2068.
10927 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
10928 and mod_include.c. [Dean Gaudet]
10930 *) Variable 'cwd' was being used pointlessly before being set.
10933 *) SIGURG doesn't exist on all platforms.
10934 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
10936 *) When an error occurs during a POST, or other operation with a
10937 request body, the body has to be read from the net before allowing
10938 a keepalive session to continue. [Roy Fielding] PR#1399
10940 *) When an error occurs in fcntl() locking suggest the user look up
10941 the docs for LockFile. [Dean Gaudet]
10943 *) table_set() and table_unset() did not deal correctly with
10944 multiple occurrences of the same key. [Stephen Scheck
10945 <sscheck@infonex.net>, Ben Laurie] PR#1604
10947 *) send_fd_length() did not calculate total_bytes_sent properly in error
10948 cases. [Ben Reser <breser@regnow.com>] PR#1366
10950 *) r->connection->user was allocated in the wrong pool causing corruption
10951 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
10953 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10954 Also removed the auto-generated link to www.apache.org that was the
10955 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10957 *) Multiple "close" tokens may have been set in the "Connection"
10958 header, not an error, but a waste.
10959 [Ronald.Tschalaer@psi.ch] PR#1683
10961 *) "basic" and "digest" auth tokens should be tested case-insensitive.
10962 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
10964 *) It appears the "257th byte" bug (see
10965 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
10966 at the 256th byte as well. Fixed. [Dean Gaudet]
10968 *) mod_rewrite would not handle %3f properly in some situations.
10971 *) Apache could generate improperly chunked HTTP/1.1 responses when
10972 the bputc() or rputc() functions were used by modules (such as
10973 mod_include). [Dean Gaudet]
10975 *) #ifdef wrap a few #defines in httpd.h to make life easier on
10976 some ports. [Ralf Engelschall]
10978 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
10980 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
10982 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
10984 Changes with Apache 1.2.5
10986 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
10987 only an issue on systems without a MAXDNAME define or where
10988 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
10990 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
10993 *) Fix core dump in the ftp proxy when reading incorrectly formatted
10994 directory listings. [Marc Slemko]
10996 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
10999 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
11000 is used to read various types of files such as htaccess and
11001 htpasswd files. [Marc Slemko]
11003 *) SECURITY: Ensure that the buffer returned by ht_time is always
11004 properly null terminated. [Marc Slemko]
11006 *) SECURITY: General mod_include cleanup, including fixing several
11007 possible buffer overflows and a possible infinite loop. This cleanup
11008 was done against 1.3 code and then backported to 1.2, the result
11009 is a large difference (due to indentation cleanup in 1.3 code).
11010 Users interested in seeing a smaller set of relevant differences
11011 should consider comparing against src/modules/standard/mod_include.c
11012 from the 1.3b3 release. Non-indentation changes to mod_include
11013 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
11015 *) SECURITY: Numerous changes to mod_imap in a general cleanup
11016 including fixing a possible buffer overflow. This cleanup also
11017 was done with 1.3 code as a basis, see the the previous note
11018 about mod_include. [Dean Gaudet]
11020 *) SECURITY: If a htaccess file can not be read due to bad
11021 permissions, deny access to the directory with a HTTP_FORBIDDEN.
11022 The previous behavior was to ignore the htaccess file if it could not
11023 be read. This change may make some setups with unreadable
11024 htaccess files stop working. PR#817 [Marc Slemko]
11026 *) SECURITY: no2slash() was O(n^2) in the length of the input.
11027 Make it O(n). This inefficiency could be used to mount a denial
11028 of service attack against the Apache server. Thanks to
11029 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
11030 this. [Dean Gaudet]
11032 *) mod_include used uninitialized data for some uses of && and ||.

11038 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
11040 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
11041 r->filename. Since those two are meant to be in sync with each other
11042 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
11044 *) mod_include did not properly handle all possible redirects from sub-
11045 requests. [Ken Coar]
11047 *) Inetd mode (which is buggy) uses timeouts without having setup the
11048 jmpbuffer. [Dean Gaudet] PR#1064

11051 reporting a select error over and over.
11052 [Rick Franchuk <rickf@transpect.net>] PR#1107
11054 Changes with Apache 1.2.4
11056 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
11057 always making requests with the full-URI instead of just the URI path.
11058 [Marc Slemko, Roy Fielding]
11060 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
11061 on this platform. [Marc Slemko]
11063 Changes with Apache 1.2.3
11065 *) The request to a remote proxy was mangled if it was generated as the
11066 result of a ProxyPass directive. URL schemes other than http:// were not
11067 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

11070 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11071 information for case where proxy module is not available. [Marc Slemko]
11073 *) Force proxy to always respond as HTTP/1.0, which it was failing to
11074 do for errors and cached responses. [Roy Fielding]
11076 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
11078 Changes with Apache 1.2.2 [not released]
11080 *) Fixed another long-standing bug in sub_req_lookup_file where it would
11081 happily skip past access checks on subdirectories looked up with relative
11082 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
11085 *) Add lockfile name to error message printed out when
11086 USE_FLOCK_SERIALIZED_ACCEPT is defined.
11089 *) Enhanced the chunking and error handling inside the buffer functions.
11090 [Dean Gaudet, Roy Fielding]
11092 *) When merging the main server's <Directory> and <Location> sections into
11093 a vhost, put the main server's first and the vhost's second. Otherwise
11094 the vhost can't override the main server. [Dean Gaudet] PR#717
11096 *) The <Directory> code would merge and re-merge the same section after
11097 a match was found, possibly causing problems with some modules.
11100 *) Fixed an infinite loop in mod_imap for references above the server root.
11101 [Dean Gaudet] PR#748
11103 *) mod_include cleanup showed that handle_else was being used to handle
11104 endif. It didn't cause problems, but it was cleaned up too.
11107 *) Last official synchronization of mod_rewrite with author version (because
11108 mod_rewrite is now directly developed by the author at the Apache Group):
11109 o added diff between mod_rewrite 3.0.6+ and 3.0.9
11110 minus WIN32/NT stuff, but plus copyright removement.
11112 - workaround for detecting infinite rewriting loops
11113 - fixed setting of env vars when "-" is used as subst string
11114 - fixed forced response code on redirects (PR#777)
11115 - fixed cases where r->args is ""
11116 - kludge to disable locking on pipes under braindead SunOS
11117 - fix for rewritelog in cases where remote hostname is unknown
11118 - fixed totally damaged request_rec walk-back loop
11119 o remove static from local data and add static to global ones.
11120 o replaced ugly proxy finding stuff by simple
11121 find_linked_module("mod_proxy") call.
11122 o added missing negation char on rewritelog()

11154 *) API: In HTTP/1.1, whether or not a request message contains a body
11155 is independent of the request method and based solely on the presence
11156 of a Content-Length or Transfer-Encoding. Therefore, our default
11157 handlers need to be prepared to read a body even if they don't know
11158 what to do with it; otherwise, the body would be mistaken for the
11159 next request on a persistent connection. discard_request_body()

11180 (headers, readmes, titles), mod_negotiation (type maps), or
11181 mod_cern_meta (meta files). [Dean Gaudet]

11215 this should make supporting large numbers of vhosts with many open
11216 log files more feasible. If this causes trouble please report it,
11217 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
11218 [Dean Gaudet] various PRs
11220 *) Related to the last entry, network sockets are now opened before
11221 log files are opened. The only known case where this can cause
11222 problems is under Solaris with many virtualhosts and many Listen
11223 directives. But using -DHIGH_SLACK_LINE=256 described above will
11224 work around this problem. [Dean Gaudet]
11226 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
11229 *) Improved unix error response logging. [Marc Slemko]
11231 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
11232 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
11233 when a URL http://... was used in conjunction with a special
11234 redirect flag, e.g. R=permanent, the permanent status was lost.

11275 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
11276 [Doug MacEachern, Rob Hartill]
11278 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
11279 reading from one buffer and writing to another, at least until it has
11280 a custom timeout handler. [Roy Fielding and Petr Lampa]

11290 *) Virtual hosts with the same ServerName, but on different ports, were

11298 *) If multiple requests on a single connection are used to retrieve
11299 data from different virtual hosts, the virtual host list would be
11300 scanned starting with the most recently used VH instead of the first,
11301 causing most virtual hosts to be ignored.

11319 *) Configure changes: Allow for whitespace at the start of a
11320 Module declaration. Also, be more understanding about the
11321 CC=/OPTIM= format in Configuration. Finally, fix compiler
11322 flags if using HP-UX's cc compiler. [Jim Jagielski]
11324 *) Subrequests and internal redirects now inherit the_request from the
11325 original request-line. [Roy Fielding]
11327 *) Test for error conditions before creating output header fields, since
11328 we don't want the error message to include those fields. Likewise,
11329 reset the content_language(s) and content_encoding of the response
11330 before generating or redirecting to an error message, since the new
11331 message will have its own Content-* definitions. [Dean Gaudet]
11333 *) Restored the semantics of headers_out (headers sent only with 200..299
11334 and 304 responses) and err_headers_out (headers sent with all responses).
11335 Avoid the overhead of copying tables if err_headers_out is empty
11336 (the usual case). [Roy Fielding]
11338 *) Fixed a couple places where a check for the default Content-Type was
11339 not properly checking both the value configured by the DefaultType
11340 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
11341 of DEFAULT_TYPE to match the documented default (text/plain).

11347 *) Properly initialize the flock structures used by the mutex locking
11348 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
11351 *) The method for determining PATH_INFO has been restored to the pre-1.2b
11352 (and NCSA httpd) definition wherein it was the extra path info beyond
11353 the CGI script filename. The environment variable FILEPATH_INFO has
11354 been removed, and instead we supply the original REQUEST_URI to any
11355 script that wants to be Apache-specific and needs the real URI path.
11356 This solves a problem with existing scripts that use extra path info
11357 in the ScriptAlias directive to pass options to the CGI script.
11360 *) The _default_ change in 1.2b10 will change the behaviour on configs
11361 that use multiple Listen statements for listening on multiple ports.
11362 But that change is necessary to make _default_ consistent with other
11363 forms of <VirtualHost>. It requires such configs to be modified
11364 to use <VirtualHost _default_:*>. The documentation has been
11365 updated. [Dean Gaudet] PR#530
11367 *) If an ErrorDocument CGI script is used to respond to an error
11368 generated by another CGI script which has already read the message
11369 body of the request, the server would block trying to read the

11391 Changes with Apache 1.2b9 [never announced]
11393 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
11394 changes and in anticipation of 1.2 final release. [Roy Fielding]
11396 *) Fix problem with scripts not receiving a SIGPIPE when client drops
11397 the connection (e.g., when user presses Stop). Apache will now stop
11398 trying to send a message body immediately after an error from write.

11401 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
11402 than mod_alias, and mod_alias has higher priority than mod_proxy;
11403 rearranged other modules to enhance understanding of their purpose
11404 and relative order (and maybe even reduce some overhead).

11426 fix some misuse of the pool string allocation functions. Also fixes

11441 apache doesn't know about at all). Log 404s that occur in mod_include.
11442 [Paul Sutton, John Van Essen]
11444 *) If a soft timeout (or lingerout) occurs while trying to flush a
11445 buffer or write inside buff.c or fread'ing from a CGI's output,
11446 then the timeout would be ignored. [Roy Fielding] PR#373
11448 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
11449 parsing of headers. If the terminating empty-line CRLF occurs starting
11450 at the 256th or 257th byte of output, then Navigator will think a normal
11451 image is invalid. We are guessing that this is because their initial
11452 read of a new request uses a 256 byte buffer. We check the bytes written
11453 so far and, if we are about to tickle the bug, we instead insert a
11454 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
11456 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
11457 of an external redirection. [Roy Fielding and Paul Sutton]
11459 *) Configure would create a broken Makefile if the configuration file
11460 contained a commented-out Rule. [Roy Fielding]
11462 *) Promote per_dir_config and subprocess_env from the subrequest to the
11463 main request in mod_negotiation. In particular this fixes a bug
11464 where <Files> sections wouldn't properly apply to negotiated content.
11467 *) Fix a potential deadlock in mod_cgi script_err handling.

11470 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
11471 [Mitchell Blank Jr]

11474 .htaccess files because the RewriteBase was not replaced correctly.
11475 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
11476 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
11478 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
11479 1.x the settings are those of pre-1.2b8. For 2.x we include
11480 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
11481 HAVE_SYS_RESOURCE_H (enable the RLimit commands).

11506 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
11509 Changes with Apache 1.2b8
11511 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
11512 to it. [Marc Slemko]
11514 *) The addition of <Location> and <File> directives made the
11515 sub_req_lookup_simple() function bogus, so we now handle
11516 the special cases directly. [Dean Gaudet]
11518 *) We now try to log where the server is dumping core when a fatal
11519 signal is received. [Ken Coar]
11521 *) Improved lingering_close by adding a special timeout, removing the
11522 spurious log messages, removing the nonblocking settings (they
11523 are not needed with the better timeout), and adding commentary
11524 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
11525 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
11527 *) Send error messages about setsockopt failures to the server error
11528 log instead of stderr. [Roy Fielding]
11530 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
11532 *) Stopgap solution for CGI 3-second delay with server-side includes: if
11533 processing a subrequest, allocate memory from r->main->pool instead
11534 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
11535 in the middle of an SSI request. [Dean Gaudet] PR #122
11537 *) Fixed status of response when POST is received for a nonexistent URL
11538 (was sending 405, now 404) and when any method is sent with a
11539 full-URI that doesn't match the server and the server is not acting
11540 as a proxy (was sending 501, now 403). [Roy Fielding]
11542 *) Host port changed to unsigned short. [Ken Coar] PR #276
11544 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
11546 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
11548 *) Report extra info from errno with many errors that cause httpd to exit.
11549 spawn_child, popenf, and pclosef now have valid errno returns in the
11550 event of an error. Correct problems where errno was stomped on
11551 before being reported. [Dean Gaudet]
11553 *) In the proxy, if the cache filesystem was full, garbage_coll() was
11554 never called, and thus the filesystem would remain full indefinitely.
11555 We now also remove incomplete cache files left if the origin server
11556 didn't send a Content-Length header and either the client has aborted
11557 transfer or bwrite() to client has failed. [Petr Lampa]
11559 *) Fixed the handling of module and script-added header fields.
11560 Improved the interface for sending header fields and reduced
11561 the duplication of code between sending okay responses and errors.
11562 We now always send both headers_out and err_headers_out, and
11563 ensure that the server-reserved fields are not being overridden,
11564 while not overriding those that are not reserved. [Roy Fielding]
11566 *) Moved transparent content negotiation fields to err_headers_out
11567 to reflect above changes. [Petr Lampa]
11569 *) Fixed the determination of whether or not we should make the
11570 connection persistent for all of the cases where some other part
11571 of the server has already indicated that we should not. Also
11572 improved the ordering of the test so that chunked encoding will
11573 be set whenever it is desired instead of only when KeepAlive
11574 is enabled. Added persistent connection capability for most error
11575 responses (those that do not indicate a bad input stream) when
11576 accessed by an HTTP/1.1 client. [Roy Fielding]
11578 *) Added missing timeouts for sending header fields, error responses,
11579 and the last chunk of chunked encoding, each of which could have
11580 resulted in a process being stuck in write forever. Using soft_timeout
11581 requires that the sender check for an aborted connection rather than
11582 continuing after an EINTR. Timeouts that used to be initiated before
11583 send_http_header (and never killed) are now initiated only within or
11584 around the routines that actually do the sending, and not allowed to
11585 propagate above the caller. [Roy Fielding]
11587 *) mod_auth_anon required an @ or a . in the email address, not both.
11590 *) per_dir_defaults weren't set correctly until directory_walk for
11591 name-based vhosts. This fixes an obscure bug with the wrong config
11592 info being used for vhosts that share the same ip as the server.
11595 *) Improved generation of modules/Makefile to be more generic for
11596 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
11598 *) Generate makefile dependency for Configuration based on the actual
11599 name given when running the Configure process. [Dean Gaudet]
11601 *) Fixed problem with vhost error log not being set prior to
11602 initializing virtual hosts. [Dean Gaudet]
11604 *) Fixed infinite loop when a trailing slash is included after a type map
11605 file URL (extra path info). [Petr Lampa]
11607 *) Fixed server status updating of per-connection counters. [Roy Fielding]
11609 *) Add documentation for DNS issues (reliability and security), and try
11610 to explain the virtual host matching process. [Dean Gaudet]
11612 *) Try to continue gracefully by disabling the vhost if a DNS lookup
11613 fails while parsing the configuration file. [Dean Gaudet]
11615 *) Improved calls to setsockopt. [Roy Fielding]
11617 *) Negotiation changes: Don't output empty content-type in variant list;
11618 Output charset in variant list; Return sooner from handle_multi() if
11619 no variants found; Add handling of '*' wildcard in Accept-Charset.
11620 [Petr Lampa and Paul Sutton]
11622 *) Fixed overlaying of request/sub-request notes and headers in
11623 mod_negotiation. [Dean Gaudet]
11625 *) If two variants' charset quality are equal and one is the default
11626 charset (iso-8859-1), then prefer the variant that was specifically
11627 listed in Accept-Charset instead of the default. [Petr Lampa]
11629 *) Memory allocation problem in push_array() -- it would corrupt memory
11630 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
11632 *) invoke_handler() doesn't handle mime arguments in content-type
11633 [Petr Lampa] PR#160
11635 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
11638 *) Fixed problem with ErrorDocument not working for virtual hosts
11639 due to one of the performance changes in 1.2b7. [Dean Gaudet]
11641 *) Log an error message if we get a request header that is too long,
11642 since it may indicate a buffer overflow attack. [Marc Slemko]
11644 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
11645 not reject URLs without a double-slash, as per RFC2068 section 3.2.
11646 [Ken Coar] PR #146, #187

11654 *) Fixed error message when resource is not found and URL contains
11655 path info. [Petr Lampa and Dean Gaudet] PR #40
11657 *) Fixed user and server confusion over what should be a virtual host
11658 and what is the main server, resulting in access to something
11659 other than the name defined in the virtualhost directive (but
11660 with the same IP address) failing. [Dean Gaudet]
11662 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
11663 AIX; improves the redirection stuff to enable the users to generally
11664 redirect to http, https, gopher and ftp; added TIME variable for
11665 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
11666 special patterns >STRING, <STRING and =STRING to RewriteCond, which
11667 can be used in conjunction with %{TIME} or other variables to create
11668 time-dependent rewriting rules. [Ralf S. Engelschall]
11670 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
11671 Module authors may need to adjust their code for proper cleanup to take
11672 place (that is, call note_cleanups_for_fd()). This change fixes problems
11673 with file descriptors being erroneously closed when the proxy module was
11674 in use. [Ben Laurie]
11676 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
11677 initgroups() to hose the group information needed for later
11678 comparisons. [Randy Terbush]
11680 *) Remove unnecessary call to va_end() in create_argv() which
11681 caused a SEGV on some systems.
11683 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
11686 *) Clear memory allocated for listeners. [Randy Terbush]
11688 *) Improved handling of IP address as a virtualhost address and
11689 introduced "_default_" as a synonym for the default vhost config.

11710 - Changed login error messages to be more descriptive.
11711 - remove setting of SO_DEBUG socket option
11712 - Make ftp_getrc() more lenient about multiline responses,
11713 specifically, 230 responses which don't have continuation 230-
11714 on each line). These seem to be all NT FTP servers, and while
11715 perhaps questionable, they appear to be legal by RFC 959.
11716 - Add missing kill_timeout() after transfer to user completes.

11727 *) Eliminated possible infinite loop in mod_imap when relative URLs are
11728 used with a 'base' directive that does not have a '/' in it.
11729 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
11731 *) Reduced the default timeout from 1200 seconds to 300, and the
11732 one in the sample configfile from 400 to 300. [Marc Slemko]
11734 *) Stop vbprintf from crashing if given a NULL string pointer;
11735 print (null) instead. [Ken Coar]
11737 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
11738 [Marc Slemko and Roy Fielding]
11740 *) Fixed problem with mod_cgi-generated internal redirects trying to
11741 read the request message-body twice. [Archie Cobbs and Roy Fielding]
11743 *) Reduced timeout on lingering close, removed possibility of a blocked
11744 read causing the child to hang, and stopped logging of errors if
11745 the socket is not connected (reset by client). [Roy Fielding]
11747 *) Rearranged main child loop to remove duplication of code in
11748 select/accept and keep-alive requests, fixed several bugs regarding
11749 checking scoreboard_image for exit indication and failure to
11750 account for all success conditions and trap all error conditions,
11751 prevented multiple flushes before closing the socket; close the entire
11752 socket buffer instead of just one descriptor, prevent logging of
11753 EPROTO and ECONNABORTED on platforms where supported, and generally
11754 improved readability. [Roy Fielding]
11756 *) Extensive performance improvements. Cleaned up inefficient use of
11757 auto initializers, multiple is_matchexp calls on a static string,
11758 and excessive merging of response_code_strings. [Dean Gaudet]
11760 *) Added double-buffering to mod_include to improve performance on
11761 server-side includes. [Marc Slemko]
11763 *) Several fixes for suexec wrapper. [Randy Terbush]
11764 - Make wrapper work for files on NFS filesystem.
11765 - Fix portability problem of MAXPATHLEN.
11766 - Fix array overrun problem in clean_env().
11767 - Fix allocation of PATH environment variable
11769 *) Removed extraneous blank line is description of mod_status chars.
11772 *) Logging of errors from the call_exec routine simply went nowhere,
11773 since the logfile fd has been closed, so now we send them to stderr.
11774 [Harald T. Alvestrand]
11776 *) Fixed core dump when DocumentRoot is a CGI.
11777 [Ben Laurie, reported by geddis@tesserae.com]
11779 *) Fixed potential file descriptor leak in mod_asis; updated it and
11780 http_core to use pfopen/pfclose instead of fopen/fclose.
11781 [Randy Terbush and Roy Fielding]
11783 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
11784 as the DEC Alpha which is 64-bit but uses 32-bit ints.
11785 [Dean Gaudet and Ken Coar]
11787 *) Return a 302 response code to the client when sending a redirect
11788 due to a missing trailing '/' on a directory instead of a 301; now
11789 it is cacheable. [Markus Gyger]
11791 *) Fix condition where, if a bad directive occurs in .htaccess, and
11792 sub_request() goes first to this directory, then log_reason() will
11793 SIGSEGV because it doesn't have initialized r->per_dir_config.
11794 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
11796 *) Fix handling of lang_index in is_variant_better(). This was
11797 causing problems which resulted in the server sending the
11798 wrong language document in some cases. [Petr Lampa]
11800 *) Remove free() from clean_env() in suexec wrapper. This was nuking
11801 the clean environment on some systems.
11803 *) Tweak byteserving code (e.g. serving PDF files) to work around
11804 bugs in Netscape Navigator and Microsoft Internet Explorer.
11805 Emit Content-Length header when sending multipart/byteranges.
11808 *) Port to HI-UX/WE2. [Nick Maclaren]
11810 *) Port to HP MPE operating system for HP 3000 machines
11811 [Mark Bixby <markb@cccd.edu>]
11813 *) Fixed bug which caused a segmentation fault if only one argument
11814 given to RLimit* directives. [Ed Korthof]
11816 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
11818 *) Improved buffered output to the client by delaying the flush decision
11819 until the BUFF code is actually about to read the next request.
11820 This fixes a problem introduced in 1.2b5 with clients that send
11821 an extra CRLF after a POST request. Also improved chunked output
11822 performance by combining writes using writev() and removing as
11823 many bflush() calls as possible. NOTE: Platforms without writev()
11824 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
11825 or Configure, unless we have already done so. [Dean Gaudet]
11827 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
11829 *) Fixed mod_info output corruption bug introduced by buffer overflow
11830 fixes. [Dean Gaudet]
11832 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
11833 for the special case of a 304 response. [Paul Sutton]
11835 *) Improved handling of TRACE method by bypassing normal method handling
11836 and header parsing routines; fixed Allow response to always allow TRACE.
11839 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
11841 *) Cleaned-up some of the generated HTML. [Ken Coar]
11843 Changes with Apache 1.2b6
11845 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
11847 *) Fix typo introduced in fix for potential infinite loop around
11848 accept() in child_main(). This change caused the rev to 1.2b6.
11849 1.2b5 was never a public beta.
11851 Changes with Apache 1.2b5
11853 *) Change KeepAlive semantics (On|Off instead of a number), add
11854 MaxKeepAliveRequests directive. [Alexei Kosut]
11856 *) Various NeXT compilation patches, as well as a change in
11857 regex/regcomp.c since that file also used a NEXT define.
11860 *) Allow * to terminate the end of a directory match in mod_dir.
11861 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
11863 *) Don't call can_exec() if suexec_enabled. Calling this requires
11864 scripts executed by the suexec wrapper to be world executable, which
11865 defeats one of the advantages of running the wrapper. [Randy Terbush]
11867 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
11870 *) Migration from sprintf() to snprintf() to avoid buffer
11871 overflows. [Marc Slemko]
11873 *) Provide portable snprintf() implementation (ap_snprintf)
11874 as well as *cvt family. [Jim Jagielski]
11876 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
11879 *) Remove mod_fastcgi.c from the distribution. This module appears
11880 to be maintained more through the Open Market channels and should
11881 continue to be easily available at http://www.fastcgi.com/
11883 *) Fixed bug in modules/Makefile that wouldn't allow building in more
11884 than one subdirectory (or cleaning, either). [Jeremy Laidman]
11886 *) mod_info assumed that the config files were relative to ServerRoot.
11889 *) CGI scripts called as an error document resulting from failed
11890 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
11892 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
11895 *) Properly check errno to prevent display of a directory index
11896 when server receives a long enough URL to confuse stat().
11899 *) Several security enhancements to suexec wrapper. It is _highly_
11900 recommended that previously installed versions of the wrapper
11901 be replaced with this version. [Randy Terbush, Jason Dour]
11903 - ~user execution now properly restricted to ~user's home
11904 directory and below.
11905 - execution restricted to UID/GID > 100
11906 - restrict passed environment to known variables
11907 - call setgid() before initgroups() (portability fix)
11908 - remove use of setenv() (portability fix)
11910 *) Add HTTP/1.0 response forcing. [Ben Laurie]
11912 *) Add access control via environment variables. [Ben Laurie]
11914 *) Add rflush() function. [Alexei Kosut]
11916 *) remove duplicate pcalloc() call in new_connection().
11918 *) Fix incorrect comparison which could allow number of children =
11919 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
11920 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
11922 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
11923 AIX PS/2, CONVEXOS. [Jim Jagielski]
11925 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
11926 It's more portable. [Martin Kraemer]
11928 *) Replace references to make in Makefile.tmpl with $(MAKE).
11931 *) Add ProxyBlock directive w/IP address caching. Add IP address
11932 caching to NoCache directive as well. ProxyBlock works with all
11933 handlers; NoCache now also works with FTP for anonymous logins.
11934 Still more code cleanup. [Chuck Murcko]
11936 *) Add "header parse" API hook [Ben Laurie]
11938 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
11940 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
11942 *) Correctly allow access and auth directives in <Files> sections in
11943 server config files. [Alexei Kosut]
11945 *) Fix bug with ServerPath that could cause certain files to be not
11946 found by the server. [Alexei Kosut]
11948 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
11949 double-quote from text and so that it properly checks for unsupported
11950 status codes using the new index_of_response interface. [Roy Fielding]
11952 *) Multiple fixes to the lingering_close code in order to avoid being
11953 interrupted by a stray timeout, to avoid lingering on a connection
11954 that has already been aborted or never really existed, to ensure that
11955 we stop lingering as soon as any error condition is received, and to
11956 prevent being stuck indefinitely if the read blocks. Also improves
11957 reporting of error conditions. [Marc Slemko and Roy Fielding]
11959 *) Fixed initialization of parameter structure for sigaction.
11960 [mgyger@itr.ch, Adrian Filipi-Martin]
11962 *) Fixed reinitializing the parameters before each call to accept and
11963 select, and removed potential for infinite loop in accept.
11964 [Roy Fielding, after useful PR from adrian@virginia.edu]
11966 *) Fixed condition where, if a child fails to fork, the scoreboard would
11967 continue to say SERVER_STARTING forever. Eventually, the main process
11968 would refuse to start new children because count_idle_servers() will
11969 count those SERVER_STARTING entries and will always report that there
11970 are enough idle servers. [Phillip Vandry]
11972 *) Fixed bug in bcwrite regarding failure to account for partial writes.
11973 Avoided calling bflush() when the client is pipelining requests.
11974 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
11976 *) Added description of "." mode in server-status [Jim Jagielski]
11978 Changes with Apache 1.2b4
11980 *) Fix possible race condition in accept_mutex_init() that
11981 could leave a small security hole open allowing files to be
11982 overwritten in cases where the server UID has write permissions.
11985 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
11987 *) Fix portablity problem in util_script where ARG_MAX may not be
11988 defined for some systems.
11990 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
11993 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
11994 style magic #! token for better script portability. [Garey Smiley]
11996 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
11997 execution for ~userdir CGI. [Jason Dour]
11999 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
12001 *) Fix month off by one in suexec wrapper logging.
12003 Changes with Apache 1.2b3:
12005 *) Fix error in mod_cgi which could cause resources not to be properly
12006 freed, or worse. [Dean Gaudet]
12008 *) Fix find_string() NULL pointer dereference. [Howard Fear]
12010 *) Add set_flag_slot() at the request of Dirk and others.
12013 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
12015 *) Add changes to improve the error message given for invalid
12016 ServerName parameters. [Dirk vanGulik]
12018 *) Add "Authoritative" directive for Auth modules that don't
12019 currently have it. This gives admin control to assign authoritative
12020 control to an authentication scheme and allow "fall through" for
12021 those authentication modules that aren't "Authoritative" thereby
12022 allowing multiple authentication mechanisms to be chained.
12025 *) Remove requirement for ResourceConfig/AccessConfig if not using
12026 the three config file layout. [Randy Terbush]
12028 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
12030 *) Changes to suexec wrapper to fix the following problems:
12031 1. symlinked homedirs will kill ~userdirs.
12032 2. initgroups() on Linux 2.0.x clobbers gr->grid.
12033 3. CGI command lines paramters problems
12034 4. pw-pwdir for "docroot check" still the httpd user's pw record.
12035 [Randy Terbush, Jason Dour]
12037 *) Change create_argv() to accept variable arguments. This fixes
12038 a problem where arguments were not getting passed to the CGI via
12039 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
12041 *) Collapse multiple slashes in path URLs to properly apply
12042 handlers defined by <Location>. [Alexei Kosut]
12044 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
12046 *) Improve the accuracy of request duration timings by setting
12047 r->request_time in read_request_line() instead of read_request().
12050 *) Reset timeout while reading via get_client_block() in mod_cgi.c
12051 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
12053 *) Add the ability to pass different Makefile.tmpl files to Configure
12054 using the -make flag. [Rob Hartill]
12056 *) Fix coredump triggered when sending a SIGHUP to the server caused
12057 by an assertion failure, in turn caused by an uninitialised field in a
12061 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
12062 PATH_INFO from previous versions of Apache (in certain situations,
12063 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
12064 [later removed in 1.2b11]
12066 *) Add rwrite() function to API to allow for sending strings of
12067 arbitrary length. [Doug MacEachern]
12069 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
12071 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
12072 NeXT. [Jim Jagielski]
12074 *) Removed recent modification to promote the status code on internal
12075 redirects, since the correct fix was to change the default log format
12076 in mod_log_config so that it outputs the original status. [Rob Hartill]
12078 Changes with Apache 1.2b2:
12080 *) Update set_signals() to use sigaction() for setting handlers.
12081 This appears to fix a re-entrant problem in the seg_fault()
12082 bus_error() handlers. [Randy Terbush]
12084 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
12086 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
12088 *) proxy_http.c bugfixes: [Chuck Murcko]
12089 1) fixes possible NULL pointer reference w/NoCache
12090 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
12091 host would cache nothing if it was in the local domain,
12092 and the local domain was in the NoCache list)
12093 3) Adds Host: header when not available
12094 4) Some code cleanup and clarification
12096 *) mod_include.c bugfixes:
12097 1) Fixed an ommission that caused include variables to not
12098 be parsed in config errmsg directives [Howard Fear]
12099 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
12100 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
12101 4) Allow backslash-escaping to all quoted text
12102 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
12103 5) Pass variable to command line if not set in XSSI's env
12106 *) Fix infinite loop when processing Content-language lines in
12107 type-map files. [Alexei Kosut]
12109 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
12111 *) Fixed problem in set_[user|group] that prevented CGI execution
12112 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
12114 *) Added PORTING information file. [Jim Jagielski]
12116 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
12118 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
12120 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
12121 USE_FCNTL_SERIALIZED_ACCEPT was intended.
12123 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
12124 which caused problems of systems where socket s_addr is >32bits.
12126 *) Added comment to explain (r->chunked = 1) side-effect in
12127 http_protocol.c [Roy Fielding]
12129 *) Replaced use of index() in mod_expires.c with more appropriate
12130 and portable isdigit() test. [Ben Laurie]
12132 *) Updated Configure for ...
12133 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
12134 *-dg-dgux* (bad pattern match)
12135 QNX (DEF_WANTHSREGEX=yes)
12136 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
12138 *-unixware211 (new)
12139 and added some user diagnostic info. [Ben Laurie]
12141 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
12142 for better portability. [Jim Jagielski]
12144 *) Updated helpers/GuessOS for ...
12145 SCO 5 (recognize minor releases)
12146 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
12147 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
12148 IRIX64 (-sgi-irix64)
12149 ULTRIX (-unknown-ultrix)
12150 SINIX (-whatever-sysv4)
12151 NCR Unix (-ncr-sysv4)
12152 and fixed something in helpers/PrintPath [Ben Laurie]
12154 Changes with Apache 1.2b1

12161 logfile for each access [Mark Cox]
12163 *) Fixed bug where Redirect in .htaccess files would cause memory
12164 leak. [Nathan Neulinger]
12166 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
12168 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
12170 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
12172 Changes with Apache 1.1.0
12174 *) Bring NeXT support up to date. [Takaaki Matsumoto]
12176 *) Bring QNX support up to date. [Ben Laurie]
12178 *) Make virtual hosts default to main server keepalive parameters.
12179 [Alexei Kosut, Ben Laurie]
12181 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]

12184 in mod_proxy. [Ben Laurie]
12186 *) mod_env now turned on by default in Configuration.tmpl.
12188 *) Bugs which were fixed:
12189 a) yet more mod_proxy bugs [Ben Laurie]
12190 b) CGI works again with inetd [Alexei Kosut]
12191 c) Leading colons were stripped from passwords [osm@interguide.com]
12192 d) Another fix to multi-method Limit problem [jk@tools.de]
12194 Changes with Apache 1.1b4
12196 *) r->bytes_sent variable restored. [Robert Thau]
12198 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
12200 *) More possibly unsecure programs removed from the support directory.
12202 *) More mod_auth_msql authentication improvements.
12204 *) VirtualHosts based on Host: headers no longer conflict with the
12207 *) OS/2 compatibility enhancements. [Gary Smiley]
12209 *) POST now allowed to directory index CGI scripts.
12211 *) Actions now work with files of the default type.
12213 *) Bugs which were fixed:
12214 a) more mod_proxy bugs
12215 b) early termination of inetd requests
12216 c) compile warnings on several systems
12217 d) problems when scripts stop reading output early
12219 Changes with Apache 1.1b3
12221 *) Much of cgi-bin and all of cgi-src has been removed, due to
12222 various security holes found and that we could no longer support
12225 *) The "Set-Cookie" header is now special-cased to not merge multiple
12226 instances, since certain popular browsers can not handle multiple
12227 Set-Cookie instructions in a single header. [Paul Sutton]
12229 *) rprintf() added to buffer code, occurrences of sprintf removed.
12232 *) CONNECT method for proxy module, which means tunneling SSL should work.
12233 (No crypto needed) Also a NoCache config directive.
12235 *) Several API additions: pstrndup(), table_unset() and get_token()
12236 functions now available to modules.
12238 *) mod_imap fixups, in particular Location: headers are now complete
12241 *) New "info" module which reports on installed module set through a
12242 special URL, a la mod_status.
12244 *) "ServerPath" directive added - allows for graceful transition
12245 for Host:-header-based virtual hosts.
12247 *) Anonymous authentication module improvements.
12249 *) MSQL authentication module improvements.
12251 *) Status module design improved - output now table-based. [Ben Laurie]
12253 *) htdigest utility included for use with digest authentication
12256 *) mod_negotiation: Accept values with wildcards to be treated with
12257 less priority than those without wildcards at the same quality
12258 value. [Alexei Kosut]
12260 *) Bugs which were fixed:
12261 a) numerous mod_proxy bugs
12262 b) CGI early-termination bug [Ben Laurie]
12263 c) Keepalives not working with virtual hosts
12264 d) RefererIgnore problems
12265 e) closing fd's twice in mod_include (causing core dumps on
12266 Linux and elsewhere).
12268 Changes with Apache 1.1b2
12271 a) core dumps in mod_digest
12272 b) truncated hostnames/ip address in the logs
12273 c) relative URL's in mod_imap map files
12275 Changes with Apache 1.1b1
12277 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12279 Changes with Apache 1.0.3
12281 *) Internal redirects which occur in mod_dir.c now preserve the
12282 query portion of a request (the bit after the question mark).
12285 *) Escape active characters '<', '>' and '&' in html output in
12286 directory listings, error messages and redirection links.
12289 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12291 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12294 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12296 *) Reset timeout timer after each successful fwrite() to the network.
12297 This patch adds a reset_timeout() procedure that is called by
12298 send_fd() to reset the timeout ever time data is written to the net.
12301 *) timeout() signal handler now checks for SIGPIPE and reports
12302 lost connections in a more user friendly way. [Rob Hartill]
12304 *) Location of the "scoreboard" file which used to live in /tmp is
12305 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12306 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12308 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12310 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12311 which caused a SEGV with cookies enabled
12313 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12316 *) Log the UNIX textual error returned by some system calls, in
12317 particular errors from accept() [David Robinson]
12319 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12321 Changes with Apache 1.0.2
12323 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12324 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12326 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12329 *) past changes to http_config.c to only use the
12330 setrlimit function on systems defining RLIMIT_NOFILE
12331 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12332 for SUNOS and prototypes the needed functions.
12334 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12337 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12339 *) Merge multiple headers from CGI scripts instead of taking last
12340 one. [David Robinson]
12342 *) Add support for SCO 5. [Ben Laurie]
12344 Changes with Apache 1.0.1
12346 *) Silence mod_log_referer and mod_log_agent if not configured
12349 *) Recursive includes can occur if the client supplies PATH_INFO data
12350 and the server provider uses relative links; as file.html
12351 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
12353 *) The replacement for initgroups() did not call {set,end}grent(). This
12354 had two implications: if anything else used getgrent(), then
12355 initgroups() would fail, and it was consuming a file descriptor.
12358 *) On heavily loaded servers it was possible for the scoreboard to get
12359 out of sync with reality, as a result of a race condition.
12360 The observed symptoms are far more Apaches running than should
12361 be, and heavy system loads, generally followed by catastrophic
12362 system failure. [Ben Laurie]
12364 *) Fix typo in license. [David Robinson]
12366 Changes with Apache 1.0.0 23 Nov 1995
12368 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
12370 Changes with Apache 0.8.16 05 Nov 1995
12372 *) New man page for 'httpd' added to support directory [David Robinson]
12374 *) .htgroup files can have more than one line giving members for a
12375 given group (each must have the group name in front), for NCSA
12376 back-compatibility [Robert Thau]
12378 *) Mutual exclusion around accept() is on by default for SVR4 systems
12379 generally, since they generally can't handle multiple processes in
12380 accept() on the same socket. This should cure flaky behavior on
12381 a lot of those systems. [David Robinson]
12383 *) AddType, AddEncoding, and AddLanguage directives take multiple
12384 extensions on a single command line [David Robinson]
12386 *) UserDir can be disabled for a given virtual host by saying
12387 "UserDir disabled" in the <VirtualHost> section --- it was a bug
12388 that this didn't work. [David Robinson]
12390 *) Compiles on QNX [Ben Laurie]
12392 *) Corrected parsing of ctime time format [David Robinson]
12394 *) httpd does a perror() before exiting if it can't log its pid
12395 to the PidFile, to make diagnosing the error a bit easier.
12398 *) <!--#include file="..."--> can no longer include files in the
12399 parent directory, for NCSA back-compatibility. [David Robinson]
12401 *) '~' is *not* escaped in URIs generated for directory listings
12404 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
12406 *) Fixed bug involving handling URIs with escaped %-characters
12407 in redirects [David Robinson]
12409 Changes with Apache 0.8.15 14 Oct 1995
12411 *) Switched to new, simpler license
12413 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
12415 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
12417 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
12419 *) Correctly handles internal redirects to files with names containing '%'
12422 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
12424 *) Use geteuid() rather than getuid() to see if we have root privilege,
12425 so that server correctly resets privilege if run setuid root. [Andrew
12428 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
12431 *) Fix relative URLs in imagemap files [Randy Terbush]
12433 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
12436 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
12437 entries all name the same one. [David Robinson]
12439 *) Fix directory listings with filenames containing unusual characters
12442 *) Better URI-escaping for generated URIs in directories with filenames
12443 containing unusual characters [Ben Laurie]
12445 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
12447 *) Unblock alarms on error return from spawn_child() [David Robinson]
12449 *) Sample Config files have extra note for SCO users [Ben Laurie]
12451 *) Configuration has note for HP-UX users [Rob Hartill]
12453 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
12455 *) Nuked bogus #define in httpd.h [David Robinson]
12457 *) Better test for whether a system has setrlimit() [David Robinson]
12459 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
12461 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
12464 Changes with Apache 0.8.14 19 Sep 1995
12466 *) Compiles on SCO ODT 3.0 [Ben Laurie]
12468 *) AddDescription works (better) [Ben Laurie]
12470 *) Leaves an intelligible error diagnostic when it can't set group
12471 privileges on standalone startup [Andrew Wilson]
12473 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
12474 that machine, which claims to be BSD but does not support RLIMIT.
12477 *) gcc -Wall no longer complains about an unused variable when util.c
12478 is compiled with -DMINIMAL_DNS [Andrew Wilson]
12480 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
12482 Changes with Apache 0.8.13 07 Sep 1995
12484 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
12486 *) Have built-in imagemap code recognize & honor Point directive [James
12489 *) Generate cleaner directory listings in directories with a mix of
12490 long and short filenames [Rob Hartill]
12492 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
12494 *) Properly default ServerName for virtual servers [Robert Thau]
12496 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
12497 Paul Richards and a cast of thousands...]
12499 *) On self-identified BSD systems (we don't try to guess any more),
12500 allocate a few extra file descriptors per virtual host with setrlimit,
12501 if we can, to avoid running out. [Randy Terbush]
12503 *) Write 22-character lock file name into buffer with enough space
12504 on startup [Konstantin Olchanski]
12506 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
12509 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
12511 *) Suppress -Wall warning by initializing variable in negotiation code
12512 [Tobias Weingartner]
12514 Changes with Apache 0.8.12 31 Aug 1995
12516 *) Doesn't pause three seconds after including a CGI script which is
12517 too slow to die off (this is done by not even trying to kill off
12518 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
12519 after the entire document has been processed). [Robert Thau]
12521 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
12523 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
12525 *) Allows .htaccess files to override <Directory> sections naming the
12526 same directory [David Robinson]
12528 *) Removed an efficiency hack in sub_req_lookup_uri which was
12529 causing certain extremely marginal cases (e.g., ScriptAlias of a
12530 *particular* index.html file) to fail. [David Robinson]
12532 *) Doesn't log an error when the requested URI requires
12533 authentication, but no auth header line was supplied by the
12534 client; this is a normal condition (the client doesn't no auth is
12535 needed here yet). [Robert Thau]
12537 *) Behaves more sanely when the name server loses its mind [Sean Welch]
12539 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
12541 *) RFC931 code no longer passes out name of prior clients on current
12542 requests if the current request came from a server that doesn't
12543 do RFC931. [David Robinson]
12545 *) Configuration script accepts "Module" lines with trailing whitespace.
12548 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
12550 *) Cleaned up comments in mod_cgi.c [Robert Thau]
12552 Changes with Apache 0.8.11 24 Aug 1995
12554 *) Wildcard <Directory> specifications work. [Robert Thau]
12556 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
12558 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
12559 the file being requested itself, in addition to the directories leading
12560 up to it. [Robert Thau]
12562 *) Logs access failures due to symlink checks or invalid client address
12563 in the error log [Roy Fielding, Robert Thau]
12565 *) Symlink checks deal correctly with systems where lstat of
12566 "/path/to/some/link/" follows the link. [Thau, Fielding]
12568 *) Doesn't reset DirectoryIndex to 'index.html' when
12569 other directory options are set in a .htaccess file. [Robert Thau]
12571 *) Clarified init code and nuked bogus warning in mod_access.c
12572 [Florent Guillaume]
12574 *) Corrected several directives in sample srm.conf
12575 --- includes corrections to directory indexing icon-related directives
12576 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
12577 icons for encodings right, and turning on AddEncoding by default).
12580 *) Corrected descriptions of args to AddIcon and AddAlt in command table
12583 *) INSTALL & README mention "contributed modules" directory [Brian
12586 *) Fixed English in the license language... "for for" --> "for".
12589 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
12590 mod_alias.c, merging it almost completely with handling of Alias, and
12591 adding a 'notes' field to the request_rec which allows the CGI module
12592 to discover whether the Alias module has put this request through
12593 ScriptAlias (which it needs to know for back-compatibility, as the old
12594 NCSA code did not check Options ExecCGI in ScriptAlias directories).
12597 Changes with Apache 0.8.10 18 Aug 1995
12599 *) AllowOverride applies to the named directory, and not just
12600 subdirectories. [David Robinson]
12602 *) Do locking for accept() exclusion (on systems that need it)
12603 using a special file created for the purpose in /usr/tmp, and
12604 not the error log; using the error log causes real problems
12605 if it's NFS-mounted; this is known to be the cause of a whole
12606 lot of "server hang" problems with Solaris. [David Robinson;
12607 thanks to Merten Schumann for help diagnosing the problem].
12609 Changes with Apache 0.8.9 12 Aug 1995
12611 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
12613 *) Nested includes see environment variables of the including document,
12614 for NCSA bug-compatibility (some sites have standard footer includes
12615 which try to print out the last-modified date). [Eric Hagberg/Robert
12618 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
12619 URI as a CGI script, even if it would have been treated as something
12620 else if requested directly, for NCSA back-compatibility. (Note that
12621 this means that people who know the name of the script can see the
12622 code just by asking for it). [Robert Thau]
12624 *) New version of dbmmanage script included in support directory as
12627 *) Check if scoreboard file couldn't be opened, and say so, rather
12628 then going insane [David Robinson]
12630 *) POST to CGI works on A/UX [Jim Jagielski]
12632 *) AddIcon and AddAlt commands work properly [Rob Hartill]
12634 *) NCSA server push works properly --- the Arena bug compatibility
12635 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
12636 if you still want the workaround). [Rob Hartill]
12638 *) If client didn't submit any Accept-encodings, ignore encodings in
12639 content negotiation. (NB this will all have to be reworked anyway
12640 for the new HTTP draft). [Florent Guillaume]
12642 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
12644 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
12646 *) Give Redirect priority over Alias, for NCSA bug compatibility
12649 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
12650 paralleling earlier bug fix for CGI [David Robinson]
12652 *) If DBM auth is improperly configured, report a server error and don't
12655 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
12656 it seems to work well enough without it (even in a 10 hits/sec
12657 workout), and the overhead for the locking under A/UX is
12658 alarmingly high (though it is very low on other systems).
12659 [Eric Hagberg, Jim Jagielski]
12661 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
12663 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
12664 Behlendorf/Eric Hagberg]
12666 *) More improvements to default Configuration for A/UX [Jim Jagielski]
12668 *) Compiles clean on NEXT [Rob Hartill]
12670 *) Compiles clean on SGI [Robert Thau]
12672 Changes with Apache 0.8.8 08 Aug 1995
12674 *) SunOS library prototypes now never included unless explicitly
12675 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
12676 people using GNU libc on SunOS are screwed by prototypes for the
12679 (Those who wish to compile clean with gcc -Wall on a standard
12680 SunOS setup need the prototypes, and may obtain them using
12681 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
12682 with nonstandard libraries are presumably competent to make their
12685 *) Strips trailing '/' characters off both args to the Alias command,
12686 to make 'Alias /foo/ /bar/' work.
12688 Changes with Apache 0.8.7 03 Aug 1995
12690 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
12691 [reported by David Robinson]
12693 *) Compiles clean on OSF/1 [David Robinson]
12695 *) Added some of the more recent significant changes (AddLanguage stuff,
12696 experimental LogFormat support) to CHANGES file in distribution root
12699 Changes with Apache 0.8.6 02 Aug 1995
12701 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
12702 (If you actually wanted a conditional GET which bypassed the cache, you
12703 couldn't get it). [Reported by Roy Fielding]
12705 *) Properly terminate headers on '304 Not Modified' replies to conditional
12706 GETs --- no browser we can find cares much, but the CERN proxy chokes.
12707 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
12709 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
12711 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
12712 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
12713 and older versions don't set the __SUNPRO_C preprocessor variable). On
12714 all other systems, these are never used anyway. [Reported by Mark Cox].
12716 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
12718 Changes with Apache 0.8.5 01 Aug 1995
12720 *) Added last-minute configurable log experiment, as optional module
12722 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
12723 properly. (One-line fix to http_protocol.c).
12725 *) Work around bogus behavior when reloading from Netscape.
12726 It's Netscape's bug --- for some reason they expect a request with
12727 If-modified-since: to not function as a conditional GET if it also
12728 comes with Pragma: no-cache, which is way out of line with the HTTP
12729 spec (according to Roy Fielding, the redactor).
12731 *) Added parameter to set maximum number of server processes.
12733 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
12736 *) IdentityCheck bugfix [Chuck Murcko].
12738 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
12740 *) More sample config file corrections; add extension to AddType for
12741 *.asis, move AddType generic description to its proper place, and
12742 fix miscellaneous typos. [ Alexei Kosut ]
12744 *) Deleted the *other* reference to the regents from the Berkeley
12745 legal disclaimer (everyplace).
12747 *) Nuked Shambhala name from src/README; had already cleaned it out
12748 of everywhere else.
12750 Changes with Apache 0.8.4
12752 *) Changes to server-pool management parms --- renamed current
12753 StartServers to MinSpareServers, created separate StartServers
12754 parameter which means what it says, and renamed MaxServers to
12755 MaxSpareServers (though the old name still works, for NCSA 1.4
12756 back-compatibility). The old names were generally regarded as
12757 too confusing. Also altered "docs" in sample config files.
12759 *) More improvements to default config files ---
12760 sample directives (commented out) for XBitHack, BindAddress,
12761 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
12762 defaults, AddTypes for send-as-is and imagemap magic types, and
12763 improvements to samples for DirectoryIndex [Alexei Kosut]
12765 *) Yet more improvements to default config files --- changes to
12766 Alexei's sample AddLanguage directives, and sample LanguagePriority
12767 [ Florent Guillaume ]
12769 *) Set config file locations properly if not set in httpd.conf
12772 *) Don't escape URIs in internal redirects multiple times; don't
12773 do that when translating PATH_INFO to PATH_TRANSLATED either.
12776 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
12778 Changes with Apache 0.8.3
12780 *) Edited distribution README to *briefly* summarize installation
12781 procedures, and give a pointer to the INSTALL file in the src/
12784 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
12785 recent NCSA distributions.
12787 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
12788 exist for the same directory, use both and don't segfault. [Reported
12791 *) Proper makefile dependencies [David Robinson]
12793 *) Note (re)starts in error log --- reported by Rob Hartill.
12795 *) Only call no2slash() after get_path_info() has been done, to
12796 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
12797 reported by Andrew Wilson, though this one is probably a real bug]
12799 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
12800 dump core when Referer is not supplied. [Randy Terbush]
12802 *) Lightly edited sample config files to refer people to our documentation
12803 instead of NCSA's, and to list Rob McCool as *original* author (also
12804 deleted his old, and no doubt non-functional email address). Would be
12805 nice to have examples of new features...
12807 Changes with Apache 0.8.2 19 Jul 1995
12809 *) Added AddLanuage code [Florent Guillaume]
12811 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
12813 *) All sorts of problems when MultiViews finds a directory. It would
12814 be nice if mod_dir.c was robust enough to handle that, but for now,
12815 just punt. [reported by Brian Behlendorf]
12817 *) Wait for all children on restart, to make sure that the old socket
12818 is gone and we can reopen it. [reported by Randy Terbush]
12820 *) Imagemap module is enabled in default Configuration
12822 *) RefererLog and UserAgentLog modules properly default the logfile
12825 *) Mark Cox's mod_cookies added to the distribution as an optional
12826 module (commented out in the default Configuration, and noted as
12827 an experiment, along with mod_dld). [Mark Cox]
12829 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
12831 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
12833 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
12835 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
12838 Changes with Apache 0.8.1
12840 *) New imagemap module [Randy Terbush]
12842 *) Replacement referer log module with NCSA-compatible RefererIgnore
12843 [Matthew Gray again]
12845 *) Don't mung directory listings with very long filenames.
12846 [Florent Guillaume]
12848 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
12850 *) New config script. See INSTALL for info. [Robert Thau]
12852 *) Scoreboard mechanism for regulating the number of extant server
12853 processes. MaxServers and StartServers defaults are the same as
12854 for NCSA, but the meanings are slightly different. (Actually,
12855 I should probably lower the MaxServers default to 10).
12857 Before asking for a new connection, each server process checks
12858 the number of other servers which are also waiting for a
12859 connection. If there are more than MaxServers, it quietly dies
12860 off. Conversely, every second, the root, or caretaker, process
12861 looks to see how many servers are waiting for a new connection;
12862 if there are fewer than StartServers, it starts a new one. This
12863 does not depend on the number of server processes already extant.
12864 The accounting is arranged through a "scoreboard" file, named
12865 /tmp/htstatus.*, on which each process has an independent file
12866 descriptor (they need to seek without interference).
12868 The end effect is that MaxServers is the maximum number of
12869 servers on an *inactive* server machine, but more will be forked
12870 off to handle unusually heavy loads (or unusually slow clients);
12871 these will die off when they are no longer needed --- without
12872 reverting to the overhead of full forking operation. There is a
12873 hard maximum of 150 server processes compiled in, largely to
12874 avoid forking out of control and dragging the machine down.
12875 (This is arguably too high).
12877 In my server endurance tests, this mechanism did not appear to
12878 impose any significant overhead, even after I forced it to put the
12879 scoreboard file on a normal filesystem (which might have more
12880 overhead than tmpfs). [Robert Thau]
12882 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
12885 *) Read .htaccess files even in directory with <Directory> section.
12886 (Former incompatibility noted on mailing list, now fixed). [Robert
12889 *) "HEAD /" gives the client a "Bad Request" error message, rather
12890 than trying to send no body *and* no headers. [Cliff Skolnick].
12892 *) Don't produce double error reports for some very obscure cases
12893 mainly involving auth configuration (the "all modules decline to
12894 handle" case which is a sure sign of a server bug in most cases,
12895 but also happens when authentication is badly misconfigured).
12898 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
12899 it's *for*, and this sort of thing really shouldn't be cluttering
12900 up the Makefile). [Robert Thau]
12902 *) Incidental code cleanups in http_main.c --- stop dragging
12903 sa_client around; just declare it where used. [Robert Thau]
12905 *) Another acc-related fix. (It doesn't like const char
12906 in some places...). [Mark Cox]
12908 Changes with Shambhala 0.6.1 13 Jul 1995
12910 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
12911 Also, fixed auth typo in http_protocol.c unmasked by this fix.
12913 *) Compiles clean with acc on SunOS [Paul Sutton]
12915 *) Reordered modules in modules.c so that Redirect takes priority
12916 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
12917 believe it or not, he has an actual site with a ScriptAlias and
12918 a Redirect declared for the *exact same directory*. Even *my*
12919 compatibility fetish wouldn't motivate me to fix this if the fix
12920 required any effort, but it doesn't, so what the hey.
12922 *) Fixed to properly default several server_rec fields for virtual
12923 servers from the corresponding fields in the main server_rec.
12924 [Cliff Skolnick --- 'port' was a particular irritant].
12926 *) No longer kills off nph- child processes before they are
12927 finished sending output. [Matthew Gray]
12929 Changes with Shambhala 0.6.0 10 Jul 1995
12931 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
12932 the connection to the client in an "aborted" state, but otherwise
12933 allow whatever handlers are running to clean up. hard_timeout()s
12934 abort the request in progress completely; anything not tied to some
12935 resource pool cleanup will leak. They're still around because I
12936 haven't yet come up with a more elegant way of handling
12937 timeouts when talking to something that isn't the client. The
12938 default_handler and the dir_handler now use soft timeouts, largely
12939 so I can test the feature. [Robert Thau]
12941 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
12942 the case of log handlers dying prematurely is probably handled VERY
12943 gracelessly at this point, and if the logger stops reading input,
12944 the server will hang. (It is known to correctly restart the
12945 logging process on server restart; this is (should be!) going through
12946 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
12947 script). [Robert Thau]
12949 *) asis files supported (new module). [Robert Thau]
12951 *) IdentityCheck code is compiled in, but has not been tested. (I
12952 don't know anyone who runs identd). [Robert Thau]
12954 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
12955 came in with the request, for NCSA bug-compatibility. [Robert Thau]
12957 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
12959 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
12960 as timeouts are not in scope. [Robert Thau]
12962 *) quoted-string args in config files now handled correctly (doesn't drop
12963 the last character). [Robert Thau; reported by Randy Terbush]
12965 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
12966 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
12968 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
12969 default default type); the former default default behavior when all
12970 type-checkers defaulted had been a core dump. [Paul Sutton]
12972 *) Copy filenames out of the struct dirent when indexing
12973 directories. (On Linux, readdir() returns a pointer to the same
12974 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
12976 Changes with Shambhala 0.5.3 [not released]
12978 *) Default response handler notes "file not found" in the error log,
12979 if the file was not found. [Cliff Skolnick].
12981 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
12982 code no longer sets up bogus PATH_INFO which fakes out the directory
12983 handler). [Cliff Skolnick]
12985 Changes with Shambhala 0.5.2 06 Jul 1995
12987 *) Changes to http_main.c --- root server no longer plays silly
12988 games with SIGCHLD, and so now detects and replaces dying
12989 children. Child processes just die on SIGTERM, without taking
12990 the whole process group with them. Potential problem --- if any
12991 child process refuses to die, we hang in restart.
12992 MaxRequestsPerChild may still not work, but it certainly works
12993 better than it did before this! [Robert Thau]
12995 *) mod_dir.c bug fixes: ReadmeName and HeaderName
12996 work (or work better, at least); over-long description lines
12997 properly terminated. [Mark Cox]
12999 *) http_request.c now calls unescape_url() more places where it
13000 should [Paul Sutton].
13002 *) More directory handling bugs (reported by Cox)
13003 Parent Directory link is now set correctly. [Robert Thau]
13005 Changes with Shambhala 0.5.1 04 Jul 1995
13007 *) Generalized cleanup interface in alloc.c --- any function can be
13008 registered with alloc.c as a cleanup for a resource pool;
13009 tracking of files and file descriptors has been reimplemented in
13010 terms of this interface, so I can give it some sort of a test.
13013 *) More changes in alloc.c --- new cleanup_for_exec() function,
13014 which tracks down and closes all file descriptors which have been
13015 registered with the alloc.c machinery before the server exec()s a
13016 child process for CGI or <!--#exec-->. CGI children now get
13017 started with exactly three file descriptors open. Hopefully,
13018 this cures the problem Rob H. was having with overly persistent
13019 CGI connections. [Robert Thau]
13021 *) Mutual exclusion around the accept() in child_main() --- this is
13022 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
13023 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
13024 This uses fcntl(F_SETLK,...) on the error log descriptor because
13025 flock() on that descriptor won't work on systems which have BSD
13026 flock() semantics, including (I think) Linux 1.3 and Solaris.
13028 This does work on SunOS (when the server is idle, only one
13029 process in the pool is waiting on accept()); it *ought* to work
13030 on the other systems. [Robert Thau]
13032 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
13034 *) sizeof(*sa_client) bugfix from [Rob Hartill]
13036 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
13038 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
13039 be unnecessary if I go to the revised timeout-handling scheme).
13042 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
13043 string) even if none came in with the request. [Robert Thau]
13045 *) CHANGES file added to distribution ;-).
13047 Changes with Shambhala 0.4.5
13049 *) mod_dld --- early dynamic loading support [rst]
13050 *) Add wildcard content handlers for XBITHACK; default_hander now
13051 invoked with that mechanism (as a handler hanging off mod_core) [rst]
13052 *) XBITHACK supported as a wildcard content-handler, and
13053 configurable at run-time (not just at compile time, as in the
13054 "patchy server" releases) [rst]
13056 Changes with Shambhala 0.4.4 30 Jun 1995
13058 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
13059 *) Handle Addtype x/y .z [rst, reported by Cox]
13061 Changes with Shambhala 0.4.3
13063 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
13064 synonymous [rst, terbush]
13066 Changes with Shambhala 0.4.1 28 Jun 1995
13068 *) First-cut virtual host implementation; some refit in the config
13069 reading code, and log management, was necessary to support this [rst]
13070 *) Sub-pool machinery, originally added to avoid excessive storage
13071 allocation on listings of large directories (which turned out to
13072 be the problem that the 0.3 storage accounting was added to
13073 find). Subrequests and mod_dir changed to use subpools. [rst]
13074 *) More memory debugging --- free list consistency checks. [rst]
13075 *) Added err_headers to request_rec, with support elsewhere [rst]
13076 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
13078 Changes with Shambhala 0.3 19 Jun 1995
13080 *) Switch ONE_PROCESS to a runtime command-line option (-X)
13081 *) Don't compile in mod_ai_backcompat by default
13082 *) Switch name of server from Apache to Shambhala in Makefile
13083 *) Add some accounting routines to track memory usage in the pools,
13086 Changes with Shambhala 0.2
13088 *) Set DOCUMENT_ROOT CGI variable
13089 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
13090 *) Add critical section protection to handling of cleanup structures
13092 *) Significant code reorg within the server core to group related
13093 functions together [rst]
13094 *) Correctly handle clients that hang up before sending any request
13096 *) Replace dying child processes. [rst]
13098 Changes with Shambhala 0.1 12 Jun 1995
13100 Major rewrite of the pre-existing "patchy server" codebase, by
13101 Robert Thau (rst). Significant portions of the server code, such
13102 as configuration-file handling and HTTP authentication support,
13103 were ripped out and rewritten from scratch. Code that was not
13104 completely rewritten was significantly altered.
13106 Major changes with this release include:
13108 *) Introduction of the module API; in request handling, the central
13109 machinery just dispatches to various modules, which actually do
13110 most of the work. Configuration handling is similar --- modules
13111 declare their own commands, and the central machinery just
13112 dispatches to them.
13114 API features from shambhala/0.1 were substantially unchanged in
13115 Apache 1.0 and 1.1. (1.0 API features not yet present in this
13116 release, such as wildcard handlers and subpools, were added in
13117 subsequent Shambhala releases, and were also generally rst's
13120 *) This release included the following modules:
13122 mod_access (access control --- allow and deny directives),
13123 mod_alias (Alias and Redirect commands),
13124 mod_auth (straight HTTP authentication, based on flat-files)
13125 mod_auth_dbm (same, with dbm files)
13126 mod_cgi (CGI scripts and, in this release, ScriptAlias)
13127 mod_common_log (CLF access logs; later renamed mod_log_common)
13128 mod_dir (directory indexing)
13129 mod_include (server-side includes)
13130 mod_mime (AddType directives)
13131 mod_negotiation (content negotiation)
13132 mod_userdir (support for users' public_html directories)
13134 It also included a mod_ai_backcompat, which was a private hack
13135 for back-compatibility with rst's own AI-lab servers.
13137 All of these modules were substantially complete, and functional
13138 or nearly so (a few, which implemented features not in use at
13139 Thau's site, required patches of a few lines).
13141 *) sub-request machinery, to allow modules to determine how other
13142 modules would assign MIME types to a given file, or optionally
13143 serve its content (this is heavily used by mod_dir, mod_include
13144 and mod_negotiation).
13146 *) Resource pool system for keeping track of memory allocated and
13147 files opened in service of a particular request. Much of the
13148 code in the modules (when they weren't rewrites) was adjusted to
13149 replace a pervasive convention of using fixed-size buffers on
13150 the stack with an equally pervasive convention of using memory
13151 allocated with palloc().
13153 *) Reorganization of data structures associated with a given
13154 request to eliminate use of global variables and the troublesome
13155 unmunge_name function (used in NCSA and early Apache releases to
13156 attempt to determine the URI which mapped to a given filename
13157 --- a difficult proposition, given that it is easy to produce
13158 setups in which multiple URIs map to the same file).
13160 *) Source files renamed and rearranged
13162 *) Very simple pre-forking behavior --- parent process forked off a
13163 fixed number of children, and then just waited for SIGHUP.
13165 *) Other more minor changes too numerous to list.
13167 This release included modified versions of a lot of code from the
13168 Apache 0.6.4 public release, plus an early pre-forking patch
13169 codeveloped by Robert Thau and Rob Hartill.
13171 Changes with Apache 0.7.3 20 Jun 1995
13173 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
13174 were incorporated by Rob Hartill on the main branch while Robert Thau
13175 worked on the Shambhala rewrite above. Most were merged into the
13176 Shambala architecture after Apache 0.8.0.
13178 Changes with Apache 0.6.4 13 May 1995
13180 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
13183 Changes with Apache 0.5.1 10 Apr 1995
13185 Changes with Apache 0.4 02 Apr 1995
13187 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
13190 Changes with Apache 0.3 24 Mar 1995
13192 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
13195 Changes with Apache 0.2 18 Mar 1995
13197 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
13198 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
13199 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
