2 Changes with Apache 2.3.0
3 [Remove entries to the current 2.0 and 2.2 section below, when backported]
5 *) mod_charset_lite: Bypass translation when the source and dest charsets
6 are the same. [Jeff Trawick]
8 *) mod_mem_cache: Set content type correctly when delivering data from
9 cache. PR 39266. [Ruediger Pluem]
11 *) worker and event MPMs: fix excessive forking if fork() or child_init
12 take a long time. PR 39275.
13 [Greg Ames, Jeff Trawick, Chris Darroch <chrisd pearsoncmg.com> ]
15 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
16 [Garrett Rooney, Jim Jagielski, Paul Querna]
18 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
19 [Chris Darroch <chrisd pearsoncmg.com>]
21 *) mod_charset_lite: Remove Content-Length when output filter can
22 invalidate it. Warn when input filter can invalidate it.
25 *) mod_ssl: Fix spurious hostname mismatch warning for valid
26 wildcard certificates. PR 37911. [Nick Burch <nick torchbox.com>]
28 *) Respect GracefulShutdownTimeout in the worker and event MPMs.
29 [Chris Darroch <chrisd pearsoncmg.com>, Garrett Rooney]
31 *) Authz: Add the new module mod_authn_core that will provide common
32 authn directives such as 'AuthType', 'AuthName'. Move the directives
33 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
34 into mod_authn_core. [Brad Nicholes]
36 *) Authz: Mark the directives 'Order', 'Allow', 'Deny' and 'Satisfy' as
37 deprecated and move them into the new module mod_access_compat which
38 can be loaded to provide backwards compatibility for these directives.
41 *) Authz: Move the 'Require' directive from the core module as well as
42 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
43 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
44 logic into the authorization processing. [Brad Nicholes]
46 *) Authz: Add the new module mod_authz_core which acts as the
47 authorization provider vector and contains common authz
48 directives. [Brad Nicholes]
50 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
51 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
53 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
54 host-based access control provided by mod_authz_host and invoked

66 *) Fix typo in ProxyStatus syntax error message.
67 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
69 *) Asynchronous write completion for the Event MPM. [Brian Pane]
71 *) Added an End-Of-Request bucket type. The logging of a request and
72 the freeing of its pool are now done when the EOR bucket is destroyed.
73 This has the effect of delaying the logging until right after the last
74 of the response is sent; ap_core_output_filter() calls the access logger
75 indirectly when it destroys the EOR bucket. [Brian Pane]
77 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
78 and the format of statistical output has changed. [Colm MacCarthaigh]
80 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
82 *) Added new connection states for handler and write completion
85 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
88 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
89 allowing string-valued client certificate attributes to be used for
90 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
91 [Martin Kraemer, David Reid]

114 process pool in request processing.
115 [Chris Darroch <chrisd pearsoncmg com>]
117 *) HTML-escape the Expect error message. Not classed as security as
118 an attacker has no way to influence the Expect header a victim will
119 send to a target site. Reported by Thiago Zaninotti
120 <thiango nstalker.com>. [Mark Cox]
122 *) htdbm: Fix crash processing -d option in 64-bit mode on HP-UX.
125 *) htdbm: Warn the user when adding a plaintext password on a platform
126 where it wouldn't work with the server (i.e., anywhere that has
127 crypt()). [Jeff Trawick]

138 mod_ssl: Fix a possible crash during access control checks if a
139 non-SSL request is processed for an SSL vhost (such as the
140 "HTTP request received on SSL port" error message when an 400
141 ErrorDocument is configured, or if using "SSLEngine optional").
142 PR 37791. [Rüdiger Plüm, Joe Orton]
144 *) SECURITY: CVE-2005-3352 (cve.mitre.org)
145 mod_imagemap: Escape untrusted referer header before outputting
146 in HTML to avoid potential cross-site scripting. Change also
147 made to ap_escape_html so we escape quotes. Reported by JPCERT.
150 *) mod_proxy_ajp: Flushing of the output after each AJP chunk is now
151 configurable at runtime via the 'flushpackets' and 'flushwait' worker
152 params. Minor MMN bump. [Jim Jagielski]

173 *) core: Reject invalid Expect header immediately. PR 38123.
176 *) mod_proxy: Fix KeepAlives not being allowed and set to
177 backend servers. PR 38602. [Ruediger Pluem, Jim Jagielski]

180 close the connection. [Justin Erenkrantz, Roy T. Fielding,
181 Jim Jagielski, Ruediger Pluem]

184 PR 38340. [Aleksey Pesternikov <apesternikov yahoo.com>]
186 *) mod_proxy_balancer: Do not overwrite the status of initialized workers and
187 respect the configured status of uninitilized workers when creating a new
188 child process. [Ruediger Pluem]
190 *) mod_proxy_ajp: Crosscheck the length of the body chunk with the length of
191 the ajp message to prevent mod_proxy_ajp from reading beyond the buffer
192 boundaries and thus revealing possibly sensitive memory contents to the
193 client. [Ruediger Pluem]
195 *) Ensure that the proper status line is written to the client, fixing
196 incorrect status lines caused by filters which modify r->status without
197 resetting r->status_line, such as the built-in byterange filter.

259 only differ by the type from CACHE_OUT / CACHE_SAVE to ensure that
260 subrequests to non local resources work again. [Ruediger Pluem]
262 *) mod_proxy: Do not lowercase the entire worker name of a BalancerMember
263 since this breaks case sensitive URI's. PR36906. [Ruediger Pluem]

2848 *) This fixes a problem where the underlying cache code
2849 indicated that there was one more element on the cache
2850 than there actually was. This happened since element 0
2851 exists but is not used. This code allocates the correct
2852 number of useable elements and reports the number of

3302 to configure the maximum amount of memory the allocators will
3303 hold on to for reuse. Anything over the MaxMemFree threshold
3304 will be free()d. This directive is useful when uncommon large
3305 peaks occur in memory usage. It should _not_ be used to mask
3306 defective modules' memory use. [Sander Striker]

3309 scripts would not result in a truncated response.
3310 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
3312 *) Add a filter_init parameter to the filter registration functions
3313 so that a filter can execute arbitrary code before the handlers
3314 are invoked. This resolves a problem where mod_include requests
3315 would incorrectly return a 304. [Justin Erenkrantz]
3317 *) Fix a long-standing bug in 2.0, CGI scripts were being called

3369 helper functions and relying on current filter assumptions.
3372 Changes with Apache 2.0.39
3374 *) Fixed a build problem in htpasswd.c on Win32.
3375 [Guenter Knauf <eflash gmx.net>, Cliff Woolley]
3377 Changes with Apache 2.0.38
3379 *) Rewrite htpasswd to use APR. The removes the annoying warning about
3380 tmpnam being unsafe. [Ryan Bloom]
3382 *) We must set the MIME-type for .shtml files to text/html if we want them
3383 to be parsed for SSI tags. Add the config for that to the default
3384 config file so that it is easier to enable .shtml parsing.
3385 [Dave Dyer <ddyer real-me.net>]
3387 *) Fixed a problem with 'make install' on ReliantUnix.
3388 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
3390 *) Make the default_handler catch all requests that aren't served by
3391 another handler. This also gets us to return a 404 if a directory
3392 is requested, there is no DirectoryIndex, and mod_autoindex isn't
3393 loaded. [Justin Erenkrantz]
3395 *) Fixed the handling of nested if-statements in shtml files.
3396 PR 9866 [Brian Pane]
3398 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
3399 into a directory different from the one that was configured. This
3400 also mirrors the root= feature from 1.3. We cannot use prefix=,
3401 because both APR and APR-util resolve their installation paths at
3402 configuration time. This means that there is no variable prefix
3403 to replace. [Andreas Hasenack <andreas netbank.com.br>]
3405 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
3406 These levels of AIX don't have a thundering herd problem with
3407 accept(). [Jeff Trawick]
3409 *) prefork MPM: Ignore mutex errors during graceful restart. For
3410 certain types of mutexes (particularly SysV semaphores), we
3411 should expect to occasionally fail to obtain or release the
3412 mutex during restart processing. [Jeff Trawick]
3414 *) Fix install-bindist.sh so that it finds any perl instead of just
3415 early perl 5.x versions. This is consistent with a build/install
3416 from source, and it allows the perl scripts installed by a bindist
3417 to work on systems with perl 5.6. [Jeff Trawick]
3419 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
3420 Tru64 (and probably some other platforms). [Jeff Trawick]
3422 *) Allow CGI scripts to return their Content-Length. This also fixes a
3423 hang on HEAD requests seen on certain platforms (such as FreeBSD).
3426 *) Added log rotation based on file size to the RotateLog support
3427 utility. [Brad Nicholes]
3429 *) Fix some casting in mod_rewrite which broke random maps.
3430 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
3432 Changes with Apache 2.0.37
3434 *) allow POST method over SSL when per-directory client cert
3435 authentication is used with 'SSLOptions +OptRenegotiate' enabled
3436 and a client cert was found in the ssl session cache.
3438 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
3439 session cache when there is no cert chain in the cache. prior to
3440 the fix this situation would result in a FORBIDDEN response and
3441 error message "Cannot find peer certificate chain"
3444 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
3445 one was already sent. PR 9644 [Jeff Trawick]
3447 *) Fix the display of the default name for the mime types config
3448 file. PR 9729 [Matthew Brecknell <mbrecknell orchestream.com>]

3451 change to the Apache directory (one level above the location
3452 of Apache.exe, in the case that Apache.exe resides in bin/.)
3453 Solves the case of ServerRoot /foo paths where /foo was not
3454 on the same drive as /winnt/system32. [William Rowe]
3456 *) Make 2.0's "AcceptMutex" startup message now "completely"
3457 match how 1.3 does it. [Jim Jagielski]
3459 *) Implement a fixed size memory cache using a priority queue
3462 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
3463 querying certain other variables from config_vars.mk. PR 9316
3466 *) Added the "detached" attribute to the cgi_exec_info_t internals
3467 so that Win32 and Netware won't create a new window or console
3468 for each CGI invoked. PR 8387
3469 [Brad Nicholes, William Rowe]
3471 *) Consolidated the command line parameters and attributes that are
3472 manipulated by the optional function ap_cgi_build_command() in
3473 mod_cgi into a single structure.
3476 *) Get rid of uninitialized value errors with "apxs -q" on certain
3477 variables. [Stas Bekman <stas stason.org>]
3479 *) Fix apxs to allow it to work when the build directory is somewhere
3480 besides server-root/build. PR 8453
3481 [Jeff Trawick and a host of others]
3483 *) Allow ap_discard_request_body to be called multiple times in the
3484 same request. Essentially, ap_http_filter keeps track of whether
3485 it has sent an EOS bucket up the stack, if so, it will only ever
3486 send an EOS bucket for this request.
3487 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
3489 *) Remove all special mod_ssl URIs. This also fixes the bug where
3490 redirecting (.*) will allow an SSL protected page to be viewed
3491 without SSL. [Ryan Bloom]
3493 *) Fix the binary build install script so that the build logic
3494 created by "apxs -g" will work when the user has a binary
3495 build. [Jeff Trawick]
3497 *) Allow instdso.sh to work with full paths to the shared module.
3500 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
3501 in module for NetWare [Brad Nicholes]
3503 *) Changed cgi and piped log behavior to accept 65536 characters
3504 on Win32 (matching Linux) before deadlocking between outputing
3505 client stdin, slurping the output from stdout and then the stderr
3506 stream. PR 8179 [William Rowe]
3508 *) Fixed Win32 wintty.exe support to assure the window title is valid.
3509 Elimiates possible gpfault or garbage title without the -t option.
3512 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
3513 brigades and input filters. [Justin Erenkrantz]
3515 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
3516 body. [Justin Erenkrantz]
3518 *) NetWare: Piping log entries through RotateLogs using the
3519 CustomLogs directive is finally supported now that we have
3520 the pipes and spawning functionality working.
3523 *) SECURITY: CVE-2002-0392 (cve.mitre.org) [CERT VU#944335]

3530 *) Correctly return 413 when an invalid chunk size is given on
3531 input. Also modify ap_discard_request_body to not do anything
3532 on sub-requests or when the connection will be dropped.
3535 *) Fix the TIME_* SSL var lookups to be threadsafe. PR 9469.
3538 *) Ensure that apr_brigade_write() flushes in all of the cases that
3539 it should to avoid conditions in some modules that could cause
3540 large amounts of data to be buffered. [Cliff Woolley]
3542 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
3543 stripping the content_type from cached responses.
3546 *) apachectl passes through any httpd options. Note: apachectl
3547 should be used in preference to httpd since it ensures that any
3548 appropriate environment variables have been set up.
3551 *) Fix the combination of mod_cgid, mod_setuexec, and mod_userdir.
3552 PR 7810 [Colm MacCarthaigh <colmmacc redbrick.dcu.ie>]
3554 *) Fix suexec execution of CGI scripts from mod_include.

3557 *) Fix segfaults at startup on some platforms when mod_auth_digest,
3558 mod_suexec, or mod_ssl were used as DSO's due to the way they

3569 [Yoshiki Hayashi, Joshua Slive]
3571 *) Fix a file permissions problem which prevented mod_disk_cache
3572 from working on Unix. [Jeff Trawick]
3574 *) Add "-k start|restart|graceful|stop" support to httpd for the Unix
3575 MPMs. These have semantics very similar to the old apachectl
3576 commands of the same name. [Justin Erenkrantz, Jeff Trawick]
3578 *) Make sure that the runtime dir is created by make install.
3579 PR 9233. [Jeff Trawick]

3586 *) Win32: Fix bug in apr_sendfile() that caused incorrect operation
3587 of the %X, %b and %B logformat options. PR 8253, 8996.
3590 *) If content-encoding is already present, do not run deflate (PR 9222)
3591 [Kazuhisa ASADA <kaz asada.sytes.net>]
3593 *) The APLOG_NOERRNO flag to ap_log_[r]error() is now deprecated.
3594 It is currently ignored and it will be removed in a future release
3595 of Apache. [Jeff Trawick]
3597 *) Removed documentation references to the no-longer-supported
3598 "make certificate" feature of mod_ssl for Apache 1.3.x. Test
3599 certificates, if truly desired, can be generated using openssl
3600 commands. PR 8724. [Cliff Woolley]
3602 *) Remove SSLLog and SSLLogLevel directives in favor of having
3603 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
3605 *) OS/390: LIBPATH no longer has to be manually uncommented in
3606 envvars to get apachectl to set up httpd properly. [Jeff Trawick]
3608 *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
3609 may now be specified to the <File/Directory > container, rather
3610 than by vhost. [William Rowe]
3612 *) mod_isapi: Experimental support for faux async support for ISAPI
3613 modules. [William Rowe]
3615 *) mod_isapi: Major refactoring of the code to rely on apr internals
3616 rather than MS APIs (using our own mod_isapi.h headers for ISAPI
3617 symbol definitions.) [William Rowe]
3619 *) mod_isapi: Fixed the return string length from GetServerVariable
3620 callback, it was not including the trailing null in the consumed
3621 buffer size. This was particularly bad for Delphi 6.0 users.

3695 *) Reverted a minor optimization in mod_ssl.c that used the vhost ID
3696 as the session id context rather that a MD5 hash of that vhost ID,
3697 because it caused very long vhost id's to be unusable with mod_ssl.

3707 - Allow whitespace between the pipe and the name of the
3708 program in SSLLog "| /path/to/program". [Cliff Woolley]
3710 *) Introduce mod_ext_filter and mod_deflate experimental modules

3714 *) Changes to the worker MPM's queue management and thread
3715 synchronization code to reduce mutex contention [Brian Pane]
3717 *) Don't install *.in configuration files since we already install
3718 *-std.conf files. [Aaron Bannert]
3720 *) Many improvements to the threadpool MPM. [Aaron Bannert]
3722 *) Fix subreqs that are promoted via fast_redirect from having invalid
3723 frec->r structures. This would cause subtle errors later on in
3724 request processing such as seen in PR 7966. [Justin Erenkrantz]
3726 *) More efficient pool recycling logic for the worker MPM [Brian Pane]
3728 *) Modify the worker MPM to not accept() new connections until
3729 there is an available worker thread. This prevents queued
3730 connections from starving for processing time while long-running

3779 Added the APLOG_TOCLIENT flag to ap_log_rerror() to
3780 explicitly tell the server that warning messages should be sent
3781 to the client in addition to being recorded in the error log.
3782 Prior to this change, ap_log_rerror() always sent warning
3783 messages to the client. In one case, a faulty CGI script caused
3784 the server to send a warning message to the client that contained
3785 the full path to the CGI script. This could be considered a
3786 minor security exposure. [Bill Stoddard]
3788 *) mod_autoindex output when SuppressRules was specified would

3802 *) Change instdso.sh to use libtool --install everywhere and then
3803 clean up some stray files and symlinks that libtool leaves around
3804 on some platforms. This gets subversion building properly since
3805 it needed a re-link to be performed by libtool at install time,

3807 that requirement. [Sander Striker]

3914 cause the Apache parent process to run in the foreground (similar to
3915 -DNO_DETACH except that it doesn't switch session ids).
3918 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
3919 for those platforms that support it. If using the default
3920 implementation, this is between pthread and sysvsem in priority.
3921 This implies it's the new default for Darwin. [Jim Jagielski]

3941 *) Don't allow initialization to succeed if we can't get a socket
3942 corresponding to one of the Listen statements. [Jeff Trawick]
3944 Changes with Apache 2.0.34
3946 *) Allow all Perchild directives to accept either numerical UID/GID
3947 or logical user/group names. [Scott Lamb <slamb slamb.org>]
3949 *) Make Perchild compile cleanly and serve pages again. [Ryan Bloom]
3951 *) implement ssl proxy to support ProxyPass / https:// and the
3952 SSLProxy* directives [Doug MacEachern]
3954 *) Update mod_cgid to not do single-byte socket reads for CGI headers
3957 *) Made AB's use of the Host: header rfc2616 compliant
3958 by Taisuke Yamada <tai iij.ad.jp> [Dirk-Willem van Gulik].
3960 *) The old, legacy (and unused) code in which the scoreboard was totally
3961 and completely contained in a file (SCOREBOARD_FILE) has been
3962 removed. This does not affect scoreboards which are *mapped* to
3963 files using named-shared-memory. [Jim Jagielski]
3965 *) Change bucket brigades API to allow a "bucket allocator" to be
3966 passed in at certain points. This allows us to implement freelists
3967 so that we can stop using malloc/free so frequently.
3968 [Cliff Woolley, Brian Pane]
3970 *) Add support for macro expansion within the variable names in
3971 <!--#echo--> and <!--#set--> directives [Brian Pane]
3973 *) Fix some mod_include segfaults [Cliff Woolley, Brian Pane, Brad Nicholes]
3975 *) Update the "RedHat" Layout to match Red Hat Linux version 7. PR BZ-7422
3978 *) add compat layer to support RSA SSLC 1.x and 2.x in mod_ssl
3979 [Jon Travis, John Barbee, William Rowe, Ryan Bloom, Doug MacEachern]
3981 *) Add a new parameter to the quick_handler hook to instruct
3982 quick handlers to optionally do a lookup rather than actually
3983 serve content. This is the first of several changes required fix
3984 several problems with how quick handlers work with subrequests.
3987 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]
3989 *) [APR-related] The ordering of the default accept mutex method has
3990 been changed to better match what's done in Apache 1.3. The ordering
3991 is now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
3994 *) Ensure that the build/ directory is created when using VPATH.
3997 *) Add some popular types to the mime magic file. PR 7730.
3998 [Linus Walleij <triad df.lth.se>, Justin Erenkrantz]
4000 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
4002 *) When a proxied site was being served, Apache was replacing
4003 the original site Server header with it's own, which is not
4004 allowed by RFC2616. Fixed. [Graham Leggett]
4006 *) Fix a mod_cgid problem that left daemon processes stranded
4007 in some server restart scenarios. [Jeff Trawick]
4009 *) Added exp_foo and rel_foo variables to config_vars.mk for
4010 all Apache and Autoconf path variables (like --sysconfdir,
4011 --sbindir, etc). exp_foo is the "expanded" version, which means
4012 that all internal variable references have been interpolated.
4013 rel_foo is the same as $exp_foo, only relative to $prefix if they
4014 share a common path. [Aaron Bannert]
4016 *) Fix some restart/terminate problems in the worker MPM. Don't
4017 drop connections during graceful restart. [Jeff Trawick]
4019 *) Change the header merging behaviour in proxy, as some headers
4020 (like Set-Cookie) cannot be unmerged due to stray commas in
4021 dates. [Graham Leggett]
4023 *) Be more vocal about what AcceptMutex values we allow, to make
4024 us closer to how 1.3 does it. [Jim Jagielski]
4026 *) Get nph- CGI scripts working again. PRs 8902, 8907, 9983
4029 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
4031 *) Add accessor function to set r->content_type. From now on,
4032 ap_rset_content_type() should be used to set r->content_type.
4033 This change is required to properly implement the
4034 AddOutputFilterByType configuration directive.
4035 [Bill Stoddard, Sander Striker, Ryan Bloom]
4037 *) Add new M_FOO symbols for the WebDAV/DeltaV methods specified by
4038 RFC 3253. Improved the method name/number mapping functions.
4041 *) remove sock_enable_linger from connection.c [Ian Holsman]
4043 *) Fix for virtual host processing where the requested hostname
4044 has a '.' at the end (PR 9187) [Ryan Cruse <ryan estara.com>]
4046 *) mod_dav's APIs for REPORT response handling was changed so that
4047 providers can generate the content directly into the output filter
4048 stack, rather than buffering the response into memory. [Greg Stein]
4050 *) Fix a hang condition with graceful restart and prefork MPM
4051 in the situation where MaxClients is very high but
4052 much fewer servers are actually started at the time of the
4053 restart. [Jeff Trawick]
4055 *) Small performance fixes for mod_include [Brian Pane]
4057 *) Performance improvement for the error logger [Brian Pane]
4059 *) Change configure so that Solaris 8 and above have
4060 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
4061 according to sun people solaris 8+ doesn't have a thundering
4062 herd problem [Ian Holsman]
4064 *) Allow URIs specifying CGI scripts to include '/' at the end
4065 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
4066 which ignore '/' at the end of the names of non-directories).
4067 PR 10138 [Jeff Trawick]
4069 *) implement SSLSessionCache shmht and shmcb based on apr_rmm and
4070 apr_shm. [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4072 *) Fix apxs -g handling. Move config_vars.mk from the top build
4073 directory to the build directory. PR 10163 [Jeff Trawick]
4075 *) Fix some mod_include problems which broke evaluation of some
4076 expressions. PR 10108 [Jeff Trawick]
4078 *) Fix the calculation of request time in mod_status. [Stas Bekman]
4080 *) Fix the calculation of thread_num in the worker score structure.
4083 *) Use apr_atomic operations in managing the mod_mem_cache
4084 cache_objects for SMP scalability. (see USE_ATOMICS
4085 preprocessor directive in mod_file_cache)
4088 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
4089 preprocessor directive in mod_file_cache)
4092 *) Implement prototype mod_disk_cache for use with mod_cache.
4095 *) Add a missing manualdir entry in the Debian config.layout.
4096 [Thom May <thom planetarytramp.net>]
4098 *) Stop installing libtool for APR and tell APR where it should place
4099 its copy of libtool (via our installbuildpath layout variable).
4102 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
4103 when reading from a remote HTTP server in proxy. [Graham Leggett]
4105 *) Modify receive/send loop in proxy_http and proxy_ftp so that
4106 should it be necessary, the remote server socket is closed before
4107 transmitting the last buffer (set by ProxyIOBufferSize) to the
4108 client. This prevents the backend server from being forced to hang
4109 around while the last few bytes are transmitted to a slow client.
4110 Fix the case where no error checking was performed on the final
4111 brigade in the loop. [Graham Leggett]
4113 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
4114 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
4115 hours. [Graham Leggett, Bill Stoddard]
4117 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
4118 for a undefined variable. [Ian Holsman]
4120 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
4121 when we can't get a socket in the specified address family. We may
4122 have gotten back an IPv6 address first and yet our system is not
4123 configured to allow IPv6 sockets. [Jeff Trawick]
4125 *) Be more careful about recursively removing CVS directories. Make
4126 sure that we aren't cd'ing to their home directory first. PR: 9993
4127 [Aaron Bannert, James LewisMoss <dres lewismoss.net>]
4129 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
4130 [Dirk-Jan Faber <dirk-jan selwerd.nl>, Aaron Bannert,
4131 Thom May <thom planetarytramp.net>]
4133 *) Rename the filter ordering priorities. The recent filtering fixes
4134 have showcased problems with their usage. Therefore, we need to
4135 rename them to increase the clarity. (CONTENT->RESOURCE,
4136 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
4138 Changes with Apache 2.0.33
4140 *) Fix a problem in the new --enable-layout functionality where
4141 it wouldn't allow overrides from variables like --prefix,
4142 --bindir, etc. [Thom May <thom planetarytramp.net>]
4144 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
4145 no longer hangs around waiting for the socket to close before
4146 returning exhaustive data. [Aaron Bannert]
4148 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
4149 [Thom May <thom planetarytramp.net>]
4151 *) Change mod_ssl to always do a full startup/teardown on restarts.
4152 this allows mod_ssl to be added to a server that is already
4153 running and makes it possible to add/change certs/keys after the
4154 server has been started. [Doug MacEachern]
4156 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
4157 This pipe must be a bidirectional 'console' style relay, which
4158 mod_ssl prints all prompts to the pipe's stdin, and reads the
4159 passphrases from the pipe's stdout. [William Rowe]
4161 *) Fix bug where --sysconfdir and --localstatedir were being
4162 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
4165 *) Fix --enable-layout to work again. Caution: When specifying
4166 --enable-layout, common arguments like --prefix, --exec-prefix,
4167 etc. will be ignored and the settings from the layout will be
4168 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]
4171 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
4172 regex pattern matching for the determination of which requests
4173 to use the remote proxy for. [Jim Jagielski]
4175 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
4177 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
4178 cruft in piped logs and rewritemap child processes.
4181 *) All instances of apr_lock_t have been removed and converted
4182 to one of the following new lock APIs: apr_thread_mutex.h,
4183 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
4184 use the apr_lock.h API, as the old API will soon be deprecated.
4187 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
4188 [Ralf S. Engelschall, Cliff Woolley]
4190 *) mod-include: make it handle flush'es and fix the 'false-alarm'
4191 [Justin Erenkrantz, Brian Pane, Ian Holsman]
4193 *) ap_get_*_filter_handle() functions to allow 3rd party modules
4194 to lookup filter handles so they can bypass the filter name
4195 lookup when adding filters to a request (via ap_add_*_filter_handle())
4196 [Ryan Morgan <rmorgan covalent.net>]
4198 *) Fix for multiple file buckets on Win32, where the first file
4199 bucket would cause the immediate closure of the socket on any
4200 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
4202 *) Correct Win32 failure of mmap of a segment beyond start of the
4203 file; fixes large SSL and similar transfers. [William Rowe]
4206 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
4207 multi-process mode to not "daemonize" while detaching from the
4208 controlling terminal. This is necessary for Apache to work with
4209 process-management tools like AIX's "System Resource Controller"
4210 as well as Dan Bernstein's "daemontools".
4211 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
4213 *) Convert mod_auth_digest to use the new apr_global_mutex_t
4214 type. [Aaron Bannert]
4216 *) fix bug in mod-include where it wouldn't send a unmatched
4217 part if it was at the end of a bucket [Ian Holsman]
4219 *) worker MPM: Improve logging of errors with the interface between
4220 the listener thread and worker threads. [Jeff Trawick]
4222 *) Some browsers ignore cookies that have been merged into a
4223 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
4224 are now unmerged in the http proxy before being sent to the
4225 client. [Graham Leggett]
4227 *) Fix a problem with proxy where each entry of a duplicated
4228 header such as Set-Cookie would overwrite and obliterate the
4229 previous value of the header, resulting in multiple header
4230 values (like cookies) going missing.
4231 [Graham Leggett, Joshua Slive]
4233 *) Add the server-limit and thread-limit values to the scoreboard
4234 for the sake of third-party applications.
4235 [Adam Sussman <myddryn vishnu.vidya.com>]
4237 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
4239 *) OS/390: Get make install to properly copy DSO modules.
4242 *) Win32: Fix bug in mod_status with displaying "Restart Time"
4243 and "Server uptime".
4246 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
4248 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
4250 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
4251 [David MacKenzie <djm pix.net>]
4253 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
4254 [David MacKenzie <djm pix.net>]
4256 *) Fix segfault and display error when SSLMutex file can not be
4257 created. [Adam Sussman <myddryn vishnu.vidya.com>]
4259 *) Add reference counting to mod_mem_cache cache objects to
4260 better manage removing objects from the cache.
4263 *) Change the verbage on the ScoreBoardFile in our default configs.
4264 Also change the default to be commented out (unspecified) so we
4265 get anonymous shared memory by default. [Aaron Bannert]
4267 *) Implement new ScoreBoardFile directive logic. This affects how
4268 we create the scoreboard's shared memory segment. If the directive
4269 is present, a name-based segment is created. If the directive is
4270 not present, first an anonymous segment is created, and if that
4271 fails, a name-based segment is created from a file of the name
4272 DEFAULT_SCOREBOARD. This gives third-party applications the
4273 ability to access our scoreboard. [Aaron Bannert]
4275 *) Allow mod_deflate to work with non-GET requests and properly send
4276 Content-Lengths. [Sander Striker <striker apache.org>]
4278 *) Fix ap_directory_merge() to correctly merge configs when there is
4279 no <Directory /> block. [Justin Erenkrantz, William Rowe]
4281 *) Remove spurious debug messsages that are normal under HTTP
4282 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
4284 *) Fix a bug in mod_cgid that would prevent proper shutdown death
4285 of the cgid process. [Aaron Bannert]
4287 *) Add signal handling back in to the worker MPM for the one_process
4288 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
4290 *) Performance: Reuse per-connection transaction pools in the
4291 worker MPM, rather than destroying and recreating them. [Brian Pane]
4293 *) Remove all signals from the worker MPM's child process. Instead,
4294 the parent uses the Pipe of Death for all communication with the
4295 child processes. [Ryan Bloom]
4297 Changes with Apache 2.0.32
4299 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
4300 default if the directive is not specified. This mirrors older
4301 behavior without changes to the httpd.conf. [William Rowe]
4303 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
4304 the service, mpm and logging code, and bugs in apr_file_open_stderr
4305 and apr_file_dup2 functions. Win2K/XP services have no handles
4306 associated for stdin/out/err, which caused unpredictable behavior
4307 in the prior release. [William Rowe, Bill Stoddard]
4309 *) Win32: simplify the Application Event Log messages, since there isn't
4310 likely to be 'more information in the error log' before an error log
4311 has been opened. [William Rowe]
4313 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
4314 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
4316 *) Win32: apache -k shutdown now behaves like apache -k stop.
4319 *) Fix prefork to not kill the parent if a child hits a resource shortage
4320 on accept(). [Greg Ames]
4322 *) Fix seg faults that occur when what should be the httpd request line
4323 starts with \r\n followed by garbage. [Greg Ames]
4325 *) Allow statically linked support binaries with the new
4326 --enable-static-support flag, and enable this behavior in
4327 the binbuild script. Also add a new --enable-static-htdbm
4328 flag. [Aaron Bannert]
4330 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
4331 do only one stat() call when generating the directory listings.
4334 *) Fix resolve_symlink to save the original symlink name if known.
4337 *) Be a bit more sane with regard to CanonicalNames. If the user has
4338 specified they want to use the CanonicalName, but they have not
4339 configured a port with the ServerName, then use the same port that
4340 the original request used. [Ryan Bloom and Ken Coar]
4342 *) In core_input_filter, check for an empty brigade after
4343 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
4344 client says it will post some data but we get FIN before any
4345 data arrives. [Jeff Trawick]
4347 *) Not being able to bind to the socket is a fatal error. We should
4348 print an error to the console, and return a non-zero status code.
4349 With these changes, all of the Unix MPMs do that correctly.
4352 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
4353 through to CGI scripts. PR 9163
4354 [Brian Reid <breid customlogic.com>,
4355 Zvi Har'El <rl math.technion.ac.il>]
4357 *) binbuild.sh: Make sure that we use the expat from our source
4358 tree so that there aren't any surprises on the target machine.
4361 *) mod_cgid: Add retry logic for when the daemon can't fork fast
4362 enough to keep up with new requests. Start using
4363 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
4364 when we can't talk to the daemon. [Jeff Trawick]
4366 *) apxs: LTFLAGS envvar can override default libtool options. Try
4367 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
4368 the covers. [Jeff Trawick]
4370 *) The Location: response header field, used for external
4371 redirect, *must* be an absoluteURI. The Redirect directive
4372 tested for that, but RedirectMatch didn't -- it would allow
4373 almost anything through. Now it will try to turn an abs_path
4374 into an absoluteURI, but it will correctly varf like Redirect
4375 if the final redirection target isn't an absoluteURI. [Ken Coar]
4377 Changes with Apache 2.0.31
4379 *) Create the scoreboard (in the parent) in a global pool context,
4380 so it survives graceful restarts. This fixes a SEGV during
4381 graceful restarts. [Aaron Bannert]
4383 *) Add a timeout option to the proxy code 'ProxyTimeout'
4386 *) FTP directory listings are now always retrieved in ASCII mode.
4387 The FTP proxy properly escapes URI's and HTML in the generated
4388 listing, and escapes the path components when talking to the FTP
4389 server. It is now possible to browse the root directory by using
4390 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
4391 Also, the last path component may contain wildcard characters
4392 '*' and '?', and if they do, a directory listing is created instead
4393 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
4396 *) Added single-listener unserialized accept support to the
4397 worker MPM [Brian Pane]
4399 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
4400 the incoming host header through to the proxied server
4401 [Geoff <g.russell ieee.org>]
4403 *) New Directive Option for ProxyPass. It now can block a location
4404 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
4406 *) Don't let the default handler try to serve a raw directory. At
4407 best you get gibberish. Much worse things can happen depending
4408 on the OS. [Jeff Trawick]
4410 *) Change the pre_config hook to return a value. Modules can now emit
4411 an error message and then cause the server to quit gracefully during
4412 startup. This required a bump to the MMN. [Aaron Bannert]
4414 *) Fix some unix socket descriptor leaks in the handler side of
4415 mod_cgid (the part that runs in the server process). Whack a
4416 silly "close(-1)" in the handler too. [Jeff Trawick]
4418 *) Change the pre_mpm hook to return a value, so that scoreboard
4419 init errors percolate up to code that knows how to exit
4420 cleanly. This required a bump to the MMN. [Jeff Trawick]
4422 *) Add the socket back to the conn_rec and remove the create_connection
4423 hook. The create_connection hook had a design flaw that did not
4424 allow creating connections based on vhost info. [Bill Stoddard]
4426 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
4427 Resolves the common case of using negotation to resolve the request
4428 /script/foo for /script.cgi/foo. [William Rowe]
4430 *) Added new functions ap_add_(input|output)_filter_handle to
4431 allow modules to bypass the usual filter name lookup when
4432 adding hard-coded filters to a request [Brian Pane]
4434 *) caching should now work on subrequests (still very experimental)
4437 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
4439 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
4442 *) Refactor ap_rgetline so that it does not use an internal brigade.
4443 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
4445 *) Remove mod_auth_db. [Justin Erenkrantz]
4447 *) Do not install unnecessary pcre headers like config.h and internal.h.
4448 [Joe Orton <joe manyfish.co.uk>]
4450 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
4451 (as it does for a normal request). quick_handled sub-requests now work
4452 in mod-include [Ian Holsman]
4454 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
4455 'CONTENT' one, as it needs to run AFTER all content headers
4457 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
4460 *) Split out blocking from the mode in the input filters.
4463 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
4465 *) Cause Win32 to capture all child-worker process errors in
4466 Apache to the main server error log, until the child can
4467 open its own error logs. [William Rowe]
4469 *) HPUX 11.*: Do not kill the child process when accept()
4470 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
4471 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
4473 *) Fix a problem in the parsing of the <Proxy foo> directive.
4476 *) rewrite of mod_ssl input filter for better performance and less
4477 memory usage [Doug MacEachern]
4479 *) allow quick_handler to be run on subrequests. [Ian Holsman]
4481 *) mod_dav now asks its provider to place content directly into the
4482 filter stack when handling a GET request. The mod_dav/provider
4483 API has changed, so providers need to be updated. [Greg Stein]
4485 *) Clear the output socket descriptor in unixd_accept() to make sure
4486 we don't supply a bogus socket to the caller if the accept fails.
4487 This caused problems with the worker MPM, which tried to process
4488 the returned socket if it was non-NULL. [Brian Pane]
4490 *) Move a check for an empty brigade to the start of core input filter
4491 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
4493 *) Add FileETag directive to allow configurable control of what
4494 data are used to form ETag values for file-based URIs. MMN
4495 bumped to 20020111 because of fields added to the end of
4496 the core_dir_config structure. [Ken Coar]
4498 *) Fix a segfault in mod_rewrite's logging code caused by passing the
4499 wrong config to ap_get_remote_host(). [Jeff Trawick]
4501 *) Allow mod_cgid to work from a binary distribution install by
4502 using 755 for the permissions on the log directory instead of
4505 *) Fixed a segfault that happened during graceful shutdown (or when
4506 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
4508 *) Split all Win32 modules [excluding the core components mod_core,
4509 mod_so, mod_win32 and the winnt mpm] into individual loadable
4510 modules, so the administrator may individually disable the former
4511 compiled-in modules by simply commenting out their LoadModule
4512 directives. [William Rowe]
4514 *) Saved Win32 module authors and porters many future headaches, by
4515 duplicating the appropriate .h files such as os.h into the include
4516 directory, including in the build tree. [William Rowe]
4518 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
4519 Use SSL functions/macros instead of directly dereferencing SSL
4520 structures wherever possible.
4521 Add type-casts for the cases where functions return a generic pointer.
4522 Add $SSL/include to configure search path.
4523 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4525 *) Moved several pointers out of the shared Scoreboard so it is
4526 more portable, and will present the vhost name across server
4527 generation restarts. [William Rowe]
4529 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
4532 Changes with Apache 2.0.30
4534 *) Fix the main bug for FreeBSD and threaded MPM's. There are
4535 still issues (see STATUS) but at least the server will now
4536 run without crashing the machine.
4537 [David Reid, Aaron Bannert, Justin Erenkrantz]
4539 *) Fix a typo in mod_deflate's m4 config section.
4540 [albert chin <china thewrittenword.com>]
4542 *) Fix a couple of mod_proxy problems forwarding HTTP connections
4543 and handling CONNECT:
4544 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
4545 (2) Proxy failed to connect when the first IP address returned by
4546 the resolver was unreachable but a secondary IP address was.
4549 *) Fix the module identifer as shown in the docs for various core
4550 modules (e.g., the identifer for mod_log_config was previously
4551 listed as config_log_module). PR #9338
4552 [James Watson <ap2bug sowega.org>]
4554 *) Fix LimitRequestBody directive by placing it in the HTTP
4555 filter. [Justin Erenkrantz]
4557 *) Fix mod_proxy seg fault when the proxied server returns
4558 an HTTP/0.9 response or a bogus status line.
4561 *) Prevent mod_proxy from truncating one character off the
4562 end of the status line returned from the proxied server.
4563 [Adam Sussman, Bill Stoddard]
4565 *) Eliminate loop in ap_proxy_string_read().
4566 [Adam Sussman, Bill Stoddard]
4568 *) Provide $0..$9 results from mod_include regex parsing.
4571 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
4573 *) Introduced the ForceLanguagePriority directive, to prevent
4574 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
4575 when using Multiviews. [William Rowe]
4577 *) Fix a problem which prevented mod_cgid and suexec from working
4578 together reliably [Greg Ames]
4580 *) Remove the call to exit() from within mod_auth_digest's post_config
4581 phase. [Aaron Bannert]
4583 *) Fix a problem in mod_auth_digest that could potentially cause
4584 problems with initialized static data on a system that uses DSOs.
4587 *) Fix a segfault in the worker MPM that could happen during
4588 child process exits. [Brian Pane, Aaron Bannert]
4590 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
4592 *) Fix matching of vhosts by ip address so we find IPv4
4593 vhost address when target address is v4-mapped form of
4594 that address. [Jeff Trawick]
4596 *) More performance tweaks to the BNDM string-search algorithm
4597 used to find "<!--#" tokens in mod_include [Brian Pane]
4599 *) Miscellaneous small performance fixes: optimized away various
4600 string copy operations and removed large temp buffers from
4601 the stack [Brian Pane]
4603 *) Fixed startup segfault that occurred when a VirtualHost
4604 directive had a port but no address [Brian Pane]
4606 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
4608 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
4609 if oslevel < WINNT. This should fix several problems reported
4610 Against 2.0.28 on Windows 98 [Bill Stoddard]
4612 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
4613 to fail. [Bill Stoddard]
4615 *) Change core code to allow an MPM to set hard thread/server
4616 limits at startup. prefork, worker, and perchild MPMs now have
4617 directives to set these limits. [Jeff Trawick]
4619 *) Win32: The async AcceptEx() event should be autoreset upon
4620 successful completion of a wait (WaitForSingleObject). This
4621 eliminates a number of spurious
4622 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
4625 *) Move any load library path environment variables out of
4626 apachectl and into a separate environment variable file which
4627 can be more easily tailored by the admin. The environment
4628 variable file as built by Apache may have additional system-
4629 specific settings. For example, on OS/390 we tailor the heap
4630 settings to allow lots of threads. [Jeff Trawick]
4632 *) Use the new APR pool code to reduce pool-related lock
4633 contention in the worker MPM. [Sander Striker]
4635 *) The POD no longer assumes the child is listening on 127.0.0.1
4636 and now pulls the first hostname in the list of listeners to
4637 perform the dummy connect on. This fixes a bug when the user
4638 had configured the Listen directive for an IP other than
4639 127.0.0.1. This would result in undead children and error
4640 messages such as "Connection refused: connect to listener".
4643 *) The worker MPM now respects the LockFile setting, needed to
4644 avoid locking problems with NFS. [Jeff Trawick]
4646 *) Fix segfault when worker MPM receives SIGHUP.
4647 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
4649 *) Fix bug that could potentially prevent the perchild MPM from
4650 working with more than one vhost/uid. [Aaron Bannert]
4652 *) Change make install and apxs -i processing of DSO modules to
4653 perform special handling on platforms where libtool doesn't install
4654 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
4655 which prevented standard LoadModule statements from working.
4658 *) Whenever mod_so is enabled (not just when there are DSOs for
4659 our modules), do whatever special magic is required for compiling/
4660 loading third-party modules. This allows third-party DSOs to
4661 be used on an AIX build when there were no built-in modules
4662 built as DSOs. (This should help on OS/390 and BeOS as well.)
4665 *) Allow apxs to be used to build DSOs on AIX without requiring the
4666 user to hard-code the list of import files. (This should help
4667 on OS/390 and BeOS as well.) [Jeff Trawick]
4669 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
4670 PR 8563, 8919 [William Rowe]
4672 *) Get binary builds working when libapr and libaprutil are built

4676 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
4677 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
4679 *) Fix the handling of SSI directives in which the ">" of the
4680 terminating "-->" is the last byte in a file [Brian Pane]
4682 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
4683 message that we had back in apache-1.3 and still have scattered
4684 throughout our docs. [Aaron Bannert]
4686 *) Prevent the Win32 port from continuing after encountering an
4687 error in the command line args to apache. [William Rowe]
4689 *) On a error in the proxy, make it write a line to the error log
4692 *) Various mod_ssl performance improvements [Doug MacEachern]
4694 Changes with Apache 2.0.29
4696 *) Add buffering in core_output_filter to ensure that long
4697 lists of small buckets don't cause small packet writes.
4698 [Brian Pane, Ryan Bloom]
4700 *) Fix the installation target to make sure that the manual is
4701 installed in the correct location.
4702 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
4703 Gomez Henri <hgomez slib.fr>]
4705 *) Fix the cmd command for mod_include. When we are processing
4706 a cmd command, we do not want to use the r->filename to set
4707 the command name. The command comes from the SSI tag. To do this,
4708 I added a variable to the function that builds the command line
4709 in mod_cgi. This allows the include_cmd function to specify
4710 the command line itself. [Ryan Bloom]
4712 *) Change open_logs hook to return a value, allowing you
4713 to flag a error while opening logs
4714 [Ian Holsman, Doug MacEachern]
4716 *) Change post_config hook to return a value, allowing you
4717 to flag a error post config
4718 [Ian Holsman, Jeff Trawick]
4720 *) Allow SUEXEC_BIN (the path to the suexec binary that is
4721 hard-coded into the server) to be specified to the configure
4722 script by the --with-suexec-bin parameter. [Aaron Bannert]
4724 *) Fix segv in worker MPM following accept on pipe-of-death
4727 *) Add mod_deflate to experimental.

4744 [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
4746 *) The threaded MPM for Unix has been removed. Use the worker
4747 MPM instead. [various]
4749 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
4750 in logging the error from a failed DNS lookup. [Jeff Trawick]
4752 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
4755 *) Get mod_cgid killed when a MPM exits due to a fatal error.
4758 *) Fix a file descriptor leak in mod_include. When we include a
4759 file, we use a sub-request, but we didn't destroy the sub-request
4760 immediately, instead we waited until the original request was
4761 done. This patch closes the sub-request as soon as the data is
4762 done being generated. [Brian Pane <bpane pacbell.net>]
4764 *) Allow modules that add sockets to the ap_listeners list to
4765 define the function that should be used to accept on that
4766 socket. Each MPM can define their own function to use for
4767 the accept function with the MPM_ACCEPT_FUNC macro. This
4768 also abstracts out all of the Unix accept error handling
4769 logic, which has become out of synch across Unix MPMs.
4772 *) Fix a bug which would cause the response headers to be omitted
4773 when sending a negotiated ErrorDocument because the required
4774 filters were attached to the wrong request_rec.
4775 [John Sterling <sterling covalent.net>]
4777 *) Remove commas from the end of the macros that define
4778 directives that are used by MPMs. Prior to this patch,
4779 you would use these macros without commas, which was unlike
4780 the macros for any other directives. Now, the caller provides
4781 the comma rather than the macro providing it. This makes
4782 the macros look more like the rest of the directives.
4783 [Ryan Bloom and Cliff Woolley]
4785 *) Add 'redirect-carefully' environment option to disable sending
4786 redirects under special circumstances. This is helpful for
4787 Microsoft's WebFolders when accessing a directory resource via
4788 DAV methods. [Justin Erenkrantz]
4790 *) Begin to abstract out the underlying transport layer.
4791 The first step is to remove the socket from the conn_rec,
4792 the server now lives in a context that is passed to the
4793 core's input and output filters. This forces us to be very
4794 careful when adding calls that use the socket directly,
4795 because the socket isn't available in most locations.
4798 *) Really reset the MaxClients value in worker and threaded
4799 when the configured value is not a multiple of the number
4800 of threads per child. We said we did previously but we
4801 forgot to. [Jeff Trawick]
4803 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
4805 *) If shared modules are requested and mod_so is not available,
4806 produce a fatal config-time error. [Justin Erenkrantz]
4808 *) Improve http2env's performance by cutting the work it has to
4809 do. [Brian Pane <bpane pacbell.net>]

4814 Changes with Apache 2.0.28
4816 *) Fix infinite loop in mod_cgid.c.
4817 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
4819 *) When no port is given in a "ServerName host" directive, the
4820 server_rec->port is now set to zero, not 80. That allows for
4821 run-time deduction of the correct server port (depending on
4822 SSL/plain, and depending also on the current setting of
4823 UseCanonicalName). This change makes redirections
4824 work, even with https:// connections. As in Apache-1.3, the
4825 connection's actual port number is never used, only the ServerName
4826 setting or the client's Host: setting. Documentation updated
4827 to reflect the change. [Martin Kraemer]
4829 *) Add a '%{note-name}e' argument to mod-headers, which works in
4830 the same way as mod_log_confg. [Ian Holsman]
4832 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
4833 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
4834 MPMs. [Cliff Woolley]
4836 *) Introduce htdbm, a user management utility for db/dbm authorization
4837 databases. [Mladen Turk <mturk mappingsoft.com>]
4839 *) Optimize usage of strlen and strcat in ap_directory_walk.
4840 [Brian Pane <bpane pacbell.net>]
4842 Changes with Apache 2.0.27
4844 *) Introduce an Apache mod_ssl initial configuration template
4845 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
4847 *) Fixed a memory leak in the getline parsing code that could
4848 be triggered by arbitrarily large header lines. Requests
4849 from the core input filter for single lines are now limited
4850 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
4852 *) Fix a truncation bug in how we print the port on the Via: header.
4853 The routine that prints the Via: header now takes a length for
4854 the port string. [Zvi Har'El <rl math.technion.ac.il>]
4856 *) Some syntax errors in mod_mime_magic's magic file can result
4857 in a 500 error, which previously was unlogged. Now we log the
4858 error. [Jeff Trawick]
4860 *) Add the support/checkgid helper app, which checks the run-time
4861 validity of group identifiers usable in the Group directive.
4864 *) Various --enable-so options have been fixed: --enable-so is
4865 treated as "static"; explicit --enable-so=shared issues an error;
4866 and explicit --enable-so fails with error on systems without
4867 APR_HAS_DSO. [Aaron Bannert]
4869 *) Fix a segfault in the core input filter when the client socket
4870 gets disconnected unexpectedly. [Cliff Woolley]
4872 *) Fix the reporting for child processes that die. This removes
4873 all of the non-portable W* macros from Apache.
4874 [Jeff Trawick and Ryan Bloom]
4876 *) Win32: Track and display "Parent Server Generation:" in
4877 mod_status output. The generation will be bumped at
4878 server graceful restart, when the child process exits
4879 by hitting MaxRequestsPerChild or if the child
4880 process exits abnormally. [Bill Stoddard]
4882 *) Win32: Fix problem where MaxRequestsPerChild directive was
4883 not being picked up in favor of the default. Enable
4884 the parent to start up a new child process immediately upon
4885 the old child starting shutdown.
4888 *) Fix some bungling of the remote port in rfc1413.c so that
4889 IdentityCheck retrieves the proper user id instead of failing
4890 and thus always returning "nobody."
4891 [Dick Streefland <Dick.Streefland xs4all.nl>]
4893 *) Introduced thread saftey for mod_rewrite's internal cache.
4894 [Brian Pane <bpane pacbell.net>]
4896 *) Simplified mod_env's directives to behave as most directives are
4897 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
4898 directive following that UnsetEnv within the same container.
4899 Also provides a runtime startup warning if a PassEnv configured
4900 environment value is undefined. [William Rowe]
4902 *) The worker MPM is now completely ported to APR's new lock API. It
4903 uses native APR types for thread mutexes, cross-process mutexes,
4904 and condition variables. [Aaron Bannert]
4906 *) Sync up documentation to remove all references to the now deprecated
4907 Port directive. [Justin Erenkrantz]
4909 *) Moved all ldap modules from the core to httpd-ldap sub-project
4912 *) Exit when we can't listen on any of the configured ports. This
4913 is the same behavior as 1.3, and it avoids having the MPMs to
4914 deal with bogus ap_listen_rec structures. [Jeff Trawick]
4916 *) Cleanup the proxy code that creates a request to the origin
4917 server. This change adds an optional hook, which allows modules
4918 to gain control while the request is created if the proxy module
4919 is loaded. The purpose of this hook is to allow modules to add
4920 input and/or output filters to the request to the origin. While
4921 I was at it, I made the core use this hook, so that proxy request
4922 creation uses some of the code from the core. This can still be
4923 greatly improved, but this is a good start. [Ryan Bloom]
4925 Changes with Apache 2.0.26
4927 *) Port the MaxClients changes from the worker MPM to the threaded
4930 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
4931 with the new input filtering system. [Justin Erenkrantz]
4933 *) Introduce the MultiviewsMatch directive, to allow the operator
4934 to be flexible in recognizing Handlers and Filters filename
4935 extensions as part of the Multiviews matching logic, strict with
4936 MultiviewsMatch NegotiatedOnly to accept only filename extentions
4937 that designate negotiated parameters, (content type, charset, etc.)
4938 or MultiviewsAll for the 1.3 behavior of matching any files, even
4939 if they have unregistered extensions. [William Rowe]
4941 *) Fixed the configure script to add a LoadModule directive to
4942 the default httpd.conf for any module that was compiled
4943 as a DSO. [Aaron Bannert <aaron clove.org>]
4945 *) rewrite mod_ssl input filtering to work with the new input filtering
4946 system. [Justin Erenkrantz]
4948 *) prefork: Don't segfault when we are able to listen on some but
4949 not all of the configured ports. [Jeff Trawick]
4951 *) Build mod_so even if no core modules are built shared.
4952 [Aaron Bannert <aaron clove.org>]
4954 *) Introduce ap_directory_walk rewrite (with further optimizations
4955 required) to adapt to the ap_process_request_internal() changes.
4956 Optimized so subrequests and redirects now reuse previous section
4957 merges, until we mismatch with the original directory_walk, and
4958 precomputed r->finfo results will cause directory_walk to skip
4959 the most expensive phases of the function. [William Rowe]
4961 *) Allow ApacheMonitor to connect to and control Apache on other
4962 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
4964 *) Remove the Port directive. In it's place, the Listen directive
4965 is now a required directive, which tells Apache what port to
4966 listen on. The ServerName directive has also been extended
4967 to accept an optional port. If the port is specified to the
4968 ServerName, the server will report that port whenever it
4969 reports the port that it is listening on. This change was
4970 made to ease configuration errors that stem from having a Port
4971 directive, and a Listen directive. In that situation, the server
4972 would only listen to the port specified by the Listen command,
4973 which caused a lot of confusion to users. [Ryan Bloom]
4975 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
4976 build, as loadable modules. [William Rowe]
4978 *) Fix --enable-mods-shared processing. If most is specified,
4979 then all modules that can be compiled as shared modules are.
4980 [Aaron Bannert <aaron clove.org>]
4982 *) Update the mime.types file to map video/vnd.mpegurl to mxu
4983 and add commonly used audio/x-mpegurl for m3u extensions.
4984 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
4986 *) Eliminate the depreciated r->content_language, in favor of the array
4987 r->content_languages introduced many years ago. Module authors must
4988 substantially overhaul their modules, so this needs to be upgraded
4989 if the module still relied on backwards-brokeness. [William Rowe]
4991 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
4994 *) Rewrite the input filtering mechanisms to consolidate and reorganize
4995 code. In short, core_input_filter does something now and
4996 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
4998 *) Update the Win32 build to re-absorb mod_proxy and family.
5001 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
5002 current SDK.) [William Rowe]
5004 *) Some style changes to the code that does ProxyErrorOverride. Fixed
5005 config merge behaviour. [Graham Leggett]
5007 *) Allow support programs to be compiled against a static version
5008 of libapr. This allows the smaller support programs to be
5009 relocated. [Aaron Bannert <aaron clove.org>]
5011 *) Update the mime.types file to the registered media types as
5012 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
5014 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
5015 number of clients that can connect at the same time, instead of
5016 specifying the maximum number of child processes.
5017 [Aaron Bannert <aaron clove.org>]
5019 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
5020 be consistent with 1.3. [Justin Erenkrantz]
5022 *) Cache apr_explode_localtime() value for 15 seconds.
5023 [Brian Pane <bpane pacbell.net>]
5025 *) Fix mod_include to not return ETag or Last-Modified headers.
5026 [Ian Holsman <ianh cnet.com>]
5028 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
5030 *) Eliminate the wasteful run-time conversion of method names from strings
5031 to numbers in places where the methods are known at compile time.
5032 [Brian Pane <bpane pacbell.net>]
5034 *) Turn the worker MPM's queue into a LIFO. This may
5035 improve cache-hit performance under some conditions.
5036 [Aaron Bannert <aaron clove.org>]
5038 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
5039 support it. [Justin Erenkrantz]
5041 *) Cleanup the worker MPM. We no longer re-use transaction
5042 pools. This incurs less overhead than shuffling the pools
5043 around so that they can be re-used. Remove one of the
5044 queue's condition variables. We just redefined the API to
5045 state that you can't try to add more stuff than you allocated
5046 segments for. [Aaron Bannert <aaron clove.org>]
5048 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
5050 *) Fixed persistent connections when a request contains a body.
5053 *) mod_dav uses a new API to speak to the backend provider for dead
5054 property management. [Greg Stein]
5056 *) Remove the Win32 script-processing exception from mod_cgi, and
5057 roll build_command_line/build_argv_list into a unified, overrideable
5058 ap_cgi_build_command optional function. [William Rowe]
5060 *) Rewrite find_start_sequence to use a better search algorithm
5061 to find the start tag. [Justin Erenkrantz]
5063 *) Fix a seg fault in mod_include. When we are generating an
5064 internal redirect, we must set r->uri to "", not a bogus
5065 string, and not NULL. [Ryan Bloom]
5067 *) Optimized location_walk, so subrequests, redirects and second passes
5068 now reuse previous section merges on a <Location > by <Location >
5069 basis, until we mismatch with the original location_walk.
5072 *) Back out the 1.45 change to util_script.c. This change made
5073 us set the environment variable REQUEST_URI to the redirected
5074 URI, instead of the originally requested URI.
5075 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5077 *) Make mod_include do lazy evaluation of potentially expensive to
5078 compute variables. [Brian Pane <bpane pacbell.net>]
5080 *) Fix logging of bytes sent for HEAD requests. %b and %B should
5081 log either - or 0, before this patch, they were both logging
5082 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
5084 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
5085 than per character. [Brian Pane <bpane pacbell.net>]
5087 *) Normalize the primary request, redirects and sub-requests to
5088 run the same ap_process_request_internal for consistency in
5089 robustness, behavior and security. [William Rowe]
5091 *) Fix a segfault with mod_include when r->path_info is not set
5092 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
5094 *) Add -X functionality back. This indicates to all MPMs and any other
5095 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
5097 *) Some initial support for the cygwin platform [prefork only].
5098 This is not to be confused with support for the WinNT/Win32
5099 platform, which is the recommended configuration for native
5100 Win32 users. The cygwin platform support is recommended for
5101 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
5103 *) Changed syntax of Set{Input|Output}Filter. The list of filters
5104 must be semicolon delimited (if more than one filter is given.)
5105 The Set{Input|Output}Filter directive now overrides a parent
5106 container's directive (e.g. SetInputFilter in <Directory /web/foo>
5107 will override any SetInputFilter directive in <Directory /web>.)
5108 This new syntax is more consistent with Add{Input|Output}Filter
5109 directives defined in mod_mime. Also cures a bug in prior releases
5110 where the Set{Input|Output}Filter directive would corrupt the
5111 global configuration if the multiple directives were nested.
5114 *) Cured what's ailed mime for quite some time. If an AddSomething
5115 was given in the configuration (Language, Charset, Handler or
5116 Encoding) Apache would set the content type as given by AddType,
5117 but refused to check the mime.types file if AddType wasn't given
5118 for that specific extension. Setting the AddHandler for .html
5119 without setting the AddType text/html html would cause Apache to
5120 use the default content type. [William Rowe]
5122 *) Added some bulletproofing to memory allocation in the LDAP cache
5123 code. [Graham Leggett]
5125 Changes with Apache 2.0.25
5127 *) Move the installed /manual directory out of the /htdocs/ tree, so
5128 that it can be kept more independently from the remaining document
5129 root. The "Alias /manual ..." already allowed for easy projection
5130 into existing private document trees. [Martin Kraemer]
5132 *) Add specified user attributes to the environment when using
5133 mod_auth_ldap. This allows you to use mod_include to embed specified
5134 user attributes in a page like so:
5135 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
5138 *) Fix a performance problem with the worker MPM. We now create
5139 transaction pools once, and re-use them for each connection.
5140 [Aaron Bannert <aaron clove.org>]
5142 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
5143 of a 'handler' or 'filter', so that any filename extension that does
5144 not contribute to the negotiated metadata can't be served without
5145 an explicit request. E.g., if the .Z extension is associated with
5146 an unzip filter, the user request somefile.Z.html, mod_negotiation
5147 won't serve it. It can serve somefile.Z.html when somefile.Z is
5148 requested, since the .Z extension is explictly requested, if the
5149 .html extension is associated with ContentType text/html.
5152 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
5153 and corresponding AddOutputFilter syntax, to insert one or more
5154 filters by mod_mime filename extension processing.
5157 *) Fix a growing connection pool in core_output_filter() for
5158 keepalive requests. [Jeff Trawick]
5160 *) Moved split_and_pass_pretag_buckets back to being a
5161 macro at Ryans's request. Removed the return from it
5162 by setting and returning a return code instead. Updated
5163 the code to check the return code from the macro and
5164 do the right thing. [Paul J. Reder]
5166 *) Fix a segfault when a numeric value was received for Host:.
5169 *) Add a function ap_remove_input_filter. This is to match
5170 up with ap_remove_output_filter. [Ryan Bloom]
5172 *) Clean up location_walk, so that this step performs a minimum
5173 amount of redundant effort (it must be run twice, but it will no
5174 longer reparse all <Location > blocks when the request uri
5175 hadn't changed.) [William Rowe]
5177 *) Eliminate proxy: (and all other 'special') processing from the
5178 ap_directory_walk() phase. Modules that want to use special
5179 walk logic should refer to the mod_proxy map_to_location example,
5180 with it's proxy_walk and proxysection implementation. This makes
5181 either directory_walk flavor much more legible, since that phase
5182 only runs against real <Directory > blocks.
5185 *) SECURITY: Fix a security problem in mod_include which would allow
5186 an SSI document to be passed to the client unparsed.
5187 [Cliff Woolley, Brian Pane]
5189 *) Introduce the map_to_storage hook, which allows modules to bypass
5190 the directory_walk and file_walk for non-file requests. TRACE
5191 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
5192 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
5195 *) Add the ability for mod_include to add the INCLUDES filter
5196 if the file is configured for the server-parsed handler.
5197 This makes the configuration for .shtml files much easier
5198 to understand, and allows mod_include to honor Apache 1.3
5199 config files. Based on Doug MacEachern's patch to PHP
5200 to do the same thing. [Ryan Bloom]
5202 *) force OpenSSL to ignore process local-caching and to always
5203 get/set/delete sessions using mod_ssl's callbacks
5204 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
5205 Geoff Thorpe <geoff geoffthorpe.net>]
5207 *) Make the worker MPM shutdown and restart cleanly. This also
5208 cleans up some race conditions, and gets the worker using
5209 pools more cleanly. [Aaron Bannert <aaron clove.org>]
5211 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
5213 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
5215 *) Fix for mod_include. Ryan's patch to check error
5216 codes put a return in the wrong place. Also, the
5217 include handler return code wasn't being checked.
5218 I don't like macros with returns, so I converted
5219 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
5220 [Paul J. Reder <rederpj raleigh.ibm.com>]
5222 *) fix segv in mod_mime if no AddTypes are configured
5223 [John Sterling <sterling covalent.net>]
5225 *) Enable ssl client authentication at SSL_accept time
5226 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
5228 *) Fix a segfault in mod_include when the original request has no
5229 associated filename (e.g., we're filtering the error document for
5230 a bad URI). [Jeff Trawick]
5232 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
5234 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
5235 of httpd is started and shuts down due to socket conflict. Moving the
5236 call to ap_log_pid solves the problem.
5238 *) Changed the late-1.3 log_config substitution %c to %X, to log the
5239 status of the closed connection, as it conflicts with the far more
5240 common, historical ssl logging directive %...{var}c. [William Rowe]
5242 *) Added the common error/ tree to the build/install targets
5243 (similar to the common icons/ tree) for the multi-language error
5244 messages that Lars committed earlier. [William Rowe]
5246 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
5248 *) Added a default commented-out mod_ldap and mod_auth_ldap
5249 configuration to httpd-std.conf and httpd-win.conf
5252 *) Added documentation for mod_ldap and mod_auth_ldap.
5255 *) Enabled negative caching on attribute comparisons in the LDAP cache.
5256 Fixed a problem where the default cache TTL was set in milliseconds
5257 not microseconds causing the cache to time out almost immediately.
5260 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
5261 module code to follow APR. [Graham Leggett]
5263 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
5264 cleaned up when the connection pool pool is cleaned up.
5267 *) Fix a minor issue with Jeff Trawick's mod_include
5268 patch. Without this patch, the code will just allocate
5269 more bytes in get_combined_directive than are needed.
5272 *) Added the LDAP authentication module mod_auth_ldap.
5273 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
5275 *) Added the LDAP cache and connection pooling module mod_ldap.
5276 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
5278 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
5279 by allowing a module to disable itself if its prerequisites are not
5280 met. [Justin Erenkrantz]
5282 Changes with Apache 2.0.24
5284 *) Fix a couple of issues in mod_include when the tag appeared at
5285 offsets near 8192 in the file being parsed. [Jeff Trawick]
5287 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
5288 reached. [Jeff Trawick]
5290 *) Numerous improvements to the Win32 build system. Introduced command line
5291 builds without requiring .mak files for MSVC 6.0 and later versions.
5292 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
5295 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
5296 reporting of uninstalled services and other error conditions, and changed the
5297 default service name to Apache2. [William Rowe]
5299 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
5300 compatibility with existing Apache 1.3 Win32 Apache management utilites.
5301 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
5303 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
5304 [William Rowe, Greg Ames]
5306 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
5307 and RemoveCharset directives. [William Rowe]
5309 *) The Unix MPMs other than perchild now allow child server
5310 processes to use the accept mutex when starting as root and
5311 using SysV sems for the accept mutex. Previously, this
5312 combination would lead to fatal errors in the child server
5313 processes. perchild can't use SysV sems because of security
5314 issues. [Jeff Trawick, Greg Ames]
5316 *) Added Win32 revision stamp resources to all http binaries
5317 (including modules/ and support/ tools.) PR7322 [William Rowe]
5319 *) Fix ap_rvprintf to support more than 4K of data at one time.
5320 [Cody Sherr <csherr covalent.net>]
5322 *) We have always used the obsolete/deprecated Netscape syntax
5323 for our tracking cookies; now the CookieStyle directive
5324 allows the Webmaster to choose the Netscape, RFC2109, or
5325 RFC2965 format. The new CookieDomain directive allows the
5326 setting of the cookie's Domain= attribute, too. PR #s 5006,
5327 5023, 5920, 6140 [Ken Coar]
5329 *) Tweak server/Makefile so that the rules for generating exports.c
5330 are compatible with make utilities which don't expand wildcards
5331 in a dependency list (e.g., OS/390 make, certain levels of GNU
5332 make). [Jeff Trawick]
5334 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
5336 *) Begin to sanitize the MPM configuration directives. Now, all
5337 MPMs use the same functions for all common MPM directives. This
5338 should make it easier to catch all bugs in these directives once.
5339 [Cody Sherr <csherr covalent.net>]
5341 *) Close a major resource leak. Every time we had issued a
5342 graceful restart, we leaked a socket descriptor.
5345 *) Fix a problem with the new method code. We need to cast
5346 the 1 to an apr_int64_t or it will be treated as a 32-bit
5347 integer, and it will wrap after being shifted 32 times.
5348 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
5350 *) Fix a bug in mod_expires. Previous to this patch, if you
5351 told mod_expires to add 604800 seconds to the last-modified
5352 time, it actually added 604800 usec's to the last-modified time,
5353 so that when looking at the response it looked like nothing
5354 had been done. The root of the problem was that we always compute
5355 time in usec's, but we ask users to input sec's. This means we
5356 need to convert to usec's before using those values.
5359 *) The worker MPM now handles shutdown and restart requests. It
5360 definitely isn't perfect, but we do stop the servers correctly.
5361 The biggest problem right now is that SIGHUP causes the server to
5362 just die. [Ryan Bloom]
5364 Changes with Apache 2.0.23
5366 *) Use the prefork MPM by default on Unix. [various]
5368 *) Added a systray icon monitor application for Win32.
5369 [Mladen Turk <mturk mappingsoft.com>]
5371 *) mod_rewrite: Fix the line ending on some non-Unix systems for
5372 messages written to the rewrite log.
5373 [Richard Labennett <rlabenn us.ibm.com>]
5375 *) All mod_autoindex query parsing is now quietly quashed with the
5376 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
5377 still drops the column sort <a href>'s for the column headers, but
5378 IgnoreClient is required to ignore these Query options entirely.
5381 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
5382 to allow the client to select plain, FancyIndexing or HTMLTable
5383 formatting, V=[0|1] to inhibit or enable version sorting, and
5384 P=pattern to return only specific files. The old Query Arguments
5385 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
5386 as before), and O=A|D for ordering ascending or descending.
5389 *) Fixed an error in mod_include's directive parsing routines which
5390 caused #if, #elif, and #else expressions containing backslashes
5391 to be improperly evaluated. [Cliff Woolley]
5393 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
5394 drop the icon column, SuppressRules to drop the <hr> elements,
5395 and HTMLTable to create rudimentary HTML table listings (implies
5396 FancyIndexing). [William Rowe]
5398 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
5399 from Apache 1.3.15. This is needed for two reasons, first, given
5400 multiple machines within a server farm, ETags and Last-Modified
5401 stamps won't correspond from machine to machine, and second, many
5402 Unixes don't capture changes to the date or time stamp of existing
5403 files, since these don't modify the dirent itself. [William Rowe]
5405 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
5406 and DirectoryWidth options from Apache 1.3.10.
5407 [William Rowe, Ken Coar]
5409 *) Eliminated FancyIndexing directive, deprecated early in Apache
5410 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
5412 *) mod_autoindex now excludes any file names that would result in
5413 an error, other than a success or redirect. Also optimized
5414 the parent directory, always included except in the URI '/'.
5417 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
5418 negotiated index pages, and prevent the server from defaulting
5419 to an autoindex of the directory. mod_negotiation will now die
5420 with a 500 Internal Error if it could match some filenames
5421 (e.g. for mod_dir) but none can be served. mod_negotation now
5422 refuses to serve any file with an extention that mod_mime doesn't
5423 recognize, and wasn't part of the request. [William Rowe]
5425 *) Eliminate mod_cgi's handling of .exe files without the .exe file
5426 extension. This is already handled by multiviews, if the admin
5427 wishes to AddHandler .exe or define a content type handler and
5428 associate .exe files with that content type. Multiviews must be
5429 enabled to allow these to be served. [William Rowe]
5431 *) Speed up the server's response to a spike in incoming workload
5432 or restarts by assigning empty scoreboard slots to new processes
5433 when they are available. [Greg Ames]
5435 *) Add a handler to mod_includes.c. This handler is designed to
5436 implement the XbitHack directive. This can't be done with a
5437 fixup, because we need to check the content-type, which is
5438 only available in the handler phase. [Ryan Bloom]
5440 *) Make the includes filter check return codes from filters lower in
5441 the filter chain. If a lower level filter returns an error, then
5442 the request needs to stop immediately. This allows mod_include to
5443 stop parsing data once a lower filter recognizes an error.
5446 *) Add the ability to extend the methods that Apache understands
5447 and have those methods <limit>able in the httpd.conf. It uses
5448 the same bit mask/shifted offset as the original HTTP methods
5449 such as M_GET or M_POST, but expands the total bits from an int to
5450 an ap_int64_t to handle more bits for new request methods than
5451 an int provides. [Cody Sherr <csherr covalent.net>]
5453 *) Fix broken mod_mime behavior in merging its arguments. Possible
5454 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
5456 *) Solve many mod_ssl porting issues (too many to detail) with
5457 help from the whole team, but most notably [Ralf S. Engelschall,
5458 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
5459 Doug MacEachern, William Rowe, Cliff Woolley]
5461 *) More stall fixes for the threaded & worker mpm's.
5462 Make mod_status output more accurate. Don't
5463 count workers in processes which aren't actively
5464 serving requests. [Greg Ames]
5466 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
5468 *) Add a single listener/multiple worker MPM. This MPM is
5469 definately not fully correct, but it allows us to solve many
5470 of the problems that exist in the threaded MPM. This is a
5471 modified version of the threaded MPM. [Ryan Bloom]
5473 *) Improve content generation throughout Apache, providing closer
5474 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
5475 Transitional specifications. [William Rowe]
5477 Changes with Apache 2.0.22
5479 *) Fix a problem where the threaded MPM stalls after restarts or
5480 segfaults. Also prevent multiple active processes from using
5481 the same scoreboard slot. [Greg Ames]
5483 *) Apache/Win32 now fills in the service description with Apache's
5484 server version string, including loaded and advertised modules.
5487 *) Improved support for the Win32 build, to recover gracefully from
5488 missing apr or apr-util directories or the awk interpreter,
5489 create the proper cgi-bin examples, including a test-cgi.bat, and
5490 fix the perl shebang line for printenv.pl, when installing from
5491 the build environment. [William Rowe]
5493 *) Fix a segfault in threaded.c caused by passing uninitialized
5494 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
5496 *) Use new APR number conversion functions to reduce CPU consumption
5497 when setting the content length, and in mod_log_config.
5500 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
5501 where HEAD response headers were being repeated twice for
5502 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
5503 problem in the http_header filter was exposed by the recent rewrite
5504 of the content_length filter. [Taketo Kabe, Bill Stoddard]
5506 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
5507 restarts. A garbage pointer to a vhost's server_rec from the
5508 previous generation was being left around under certain
5509 conditions. [Greg Ames]
5511 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
5512 used to appear as '(none', without the closing paren.
5513 [Günter Knauf <eflash gmx.net>]
5515 *) Improve the exports generating awk script. In the past, we had
5516 work around problems in the awk script by avoiding some #if and
5517 #ifdefs. This has bitten us many times in generating the exports.c
5518 file. This improvement allows corrects the header file parsing.
5519 [Sander Striker <striker apache.org>]
5521 Changes with Apache 2.0.21
5523 *) Resolve the Win32 htpasswd bug, where a file that existed would be
5524 overwritten, regardless of the -c flag.
5525 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
5527 *) Introduce connection sub-pools into ab. Truncating the lifetime
5528 of these allocations means that ab no longer perpetually grows
5529 its working set, running out of memory on large request attempts.
5532 *) Make scoreboard creation a hook. This allows management
5533 modules to have access to the scoreboard at the time that it is
5534 created, and at every restart request.
5535 [Cody Sherr <csherr covalent.net>]
5537 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
5538 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
5539 daemon index actually used in the scoreboard. I also
5540 updated the pertinent calls. [Paul J. Reder]
5542 *) Win32: Prevent listening sockets from being inherited by
5543 the Apache child process, CGI scripts, rotatelog process
5544 etc. If the Apache child process segfaults, any processes
5545 that the child started are not reaped. Prior to this fix,
5546 these processes inherited the listening sockets which sometimes
5547 prevented the restarted Apache child process from accepting
5548 connections (ie, the server would hang).
5551 *) Provide vhost and request strings when ExtendedStatus is on.
5554 *) Fix some issues with the pod and prefork: check the pod *after*
5555 processing a connection so that a server processing a time-
5556 consuming request bails out as soon as practical; when the
5557 parent process wakes up a server process via connect(), use an
5558 APR timeout on the connect() so that we don't hang for a long
5559 time if there aren't server processes around to do accept().
5560 [Jeff Trawick, Greg Ames]
5562 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
5563 spends a lot of time in apr_table_get calls. Using the default
5564 httpd.conf, the tables for languages and charsets are somewhat
5565 large, so the time spent scanning them on each request is
5566 significant. Replacing the tables with hash tables provides
5567 a nice speedup. [Brian Pane <bpane pacbell.net>]
5569 *) Add two functions to allow modules to access random parts of the
5570 scoreboard. This allows modules compiled for one MPM to access the
5571 scoreboard, even if it the server was compiled for another MPM.
5572 [Harrie Hazewinkel <harrie covalent.net>]
5574 Changes with Apache 2.0.20
5576 *) Fix problem in content-length filter where the filter would
5577 buffer all the output from a CGI before sending any bytes
5578 down the filter stack to the network. This problem would cause
5579 significant memory consumption if the CGIs generated
5580 lots of bytes. [Bill Stoddard]
5582 *) Get non-blocking CGI pipe reads working with the bucket brigades.
5585 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
5588 *) Fix a bug in the threaded MPM that would cause it to kill off all
5589 workers immediately after starting if the number of workers started
5590 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
5592 Changes with Apache 2.0.19
5594 *) Fix problem with threaded MPM. The problem was that if each child
5595 process was busy serving a single long-lived request and the server
5596 was sent a graceful restart signal, the server would stop serving
5597 requests. This would happen because each child process would wait to
5598 die until the last thread was done, and the parent wouldn't spawn any
5599 new children until a process died. Now, the parent looks at the fact
5600 that the children are dying gracefully, and starts new children.
5601 Those new children only start enough threads to compliment the number
5602 of threads in the other child process that shares the same spot in
5603 the scoreboard. In this way, we make sure to never go over
5604 MaxClients. [Ryan Bloom]
5606 *) modified mod_negotiation and mod_autoindex to speed up by almost a
5607 factor of two on apr_dir_read()-enhanced platforms, such as Win32
5608 and OS2, by calling ap_sub_request_lookup_dirent() with the results
5609 already provided by apr_dir_read(). [William Rowe]
5611 *) mod_file_cache is now more robust to filtering and serves requests
5612 slightly more efficiently. [Cliff Woolley]
5614 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
5615 Module was calling ap_rwrite() followed by ap_rflush() but the
5616 served content was not being displayed in the browser. Inspection
5617 of the output stream revealed that the first data chunk was
5618 missing the trailing CRLF required by the RFC. [Bill Stoddard]
5620 *) apxs no longer generates ap_send_http_header() in the example handler
5622 *) Fix an ab problem which could cause a divide-by-zero exception
5623 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
5624 [Ian Holsman <ianh cnet.com>]
5626 *) Solve case-insensitive platforms' confusion about negotiated
5627 filenames, allowing files of differnt case to match in choosing
5628 the document to serve. [William Rowe]
5630 *) Fix brokenness when ThreadsPerChild is higher than the built-in
5631 limit. We left ap_threads_per_child at the higher value which
5632 led to segfaults when doing certain scoreboard operations.
5635 *) Fix seg faults and/or missing output from mod_include. The
5636 default_handler was using the subrequest pool for files and
5637 MMAPs, even though the associated APR structures typically
5638 live longer than the subrequest. [Greg Ames]
5640 *) Extend mod_setenvif to support specifying regular expressions
5641 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
5642 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
5643 will cause HAVE_TS to be set if any of the request headers begins
5644 with "TS" and has a value that begins with any character in the
5645 set [a-z]. [Bill Stoddard]
5647 *) httpd children now re-bind themselves to a random CPU on
5648 multiprocessor systems on AIX via bindprocessor() in 2.0.
5649 [Victor J. Orlikowski]
5651 *) Fix htdigest. It would go into a loop in getline when adding
5652 a second user. [Bill Stoddard]
5654 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
5656 *) Automatically generate httpd.exp for AIX.
5657 DSOs now work again on AIX in 2.0
5658 [Victor J. Orlikowski]
5660 *) Add a new request hook, error_log. This phase allows modules
5661 to act on the error log string _after_ it has been written
5662 to the error log. The goal for this hook is to allow monitoring
5663 modules to send the error string to the monitoring agent.
5666 *) Modify mod_echo to make it use filters for input and output.
5667 [Ryan Morgan <rmorgan covalent.net>]
5669 *) Extend mod_headers to support conditional driven Header
5670 add, append and set. Use SetEnvIf to set an envar and conditionally
5671 add/append/set headers based on this envar thusly:
5673 SetEnvIf TSMyHeader value HAVE_TSMyHeader
5674 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
5676 If the request contains header "TSMyHeader: value" then header
5677 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
5680 *) Extend mod_headers to support using format specifiers on Header
5681 add, append and set header values. Two format specifiers are supported:
5683 %t - reports, in UTC microseconds since the epoch, when the
5684 request was received.
5686 %D - reports the time, in microseconds, between when the request was
5687 received and the response sent.
5690 Header add MyHeader "This request served in %D microseconds. %t"
5692 results in a header being added to the response that looks like this:
5694 MyHeader: This request served in D=5438 microseconds. t=991424704447256
5698 *) Fix reset_filter(). We need to be careful how we remove filters.
5699 If we set r->output_filters to NULL, we also have to reset the
5700 connection's filters. [John Sterling]
5702 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
5704 *) Add a check to ap_die() to make sure the filter stack is sane and
5705 contains the correct basic filters when an error occurs. This fixes
5706 a problem where headers are not being sent on error. [John Sterling]
5708 *) New Header directive 'echo' option. "Header echo regex" will
5709 cause any headers received on the request that match regex to be
5710 echoed to (included in) the response headers.
5713 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
5714 This prevented the inclusion of apr_compat.h. PR #7773
5715 [Oleg Broytmann <phd phd.pp.ru>]
5717 *) Moved util_uri to the apr-util library. This required a bunch of
5718 apr_name changes for the uri utility functions. [Justin Erenkrantz]
5720 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
5721 insert_filter phase so that other filters are not bypassed by default.
5724 *) Reimplement mod_headers as an output filter. mod_headers can now
5725 add custom headers to inbound requests using the RequestHeader directive
5726 and to responses using the same old Header directive. [Graham Leggett]
5728 Changes with Apache 2.0.18
5730 *) Fix command-line processing so that if a bad argument is specified
5731 Apache will exit. [Jeff Trawick]
5733 *) Change the make targets and rules to be consistent in all of the
5734 Apache-owned source trees. [Roy Fielding]
5736 *) Fix processing of the TRACE method. Previously we passed bogus
5737 parms to form_header_field() and it overlaid some vhost structures,
5738 resulting in a segfault in check_hostalias().
5739 [Greg Ames, Jeff Trawick]
5741 *) Win32: Add support for reliable piped logs. If the logging process
5742 goes down, Apache will automatically restart it. This function has
5743 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
5746 *) Do not start piped log processes during the config file
5747 preflight. This change also circumvents a problem on
5748 Windows where the rotatelog processes created during preflight
5749 was not getting cleaned up properly.
5752 *) add "Request Phase Participation" info to mod_info
5755 *) Make first phase changes to the scoreboard data structures in
5756 preparation for the rewriting of the scoreboard per my posted
5757 design notes. [Paul J. Reder]
5759 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
5760 and apr-util, allow it to be overridden by the configure command-line
5761 (default="--silent") and introduce LT_LDFLAGS to replace what we were
5762 formerly abusing as LTFLAGS. [Roy Fielding]
5764 *) Clean up the reporting of incorrect closing container tags.
5765 [Barrie Slaymaker <barries slaysys.com>]
5767 *) Simplify the configure process by moving all libtool stuff to APR
5768 and moving hints.m4 inline. [Roy Fielding]
5770 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
5771 of functions used by mod_proxy for export in the DLL
5772 [Ian Holsman <IanH cnet.com>]
5774 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
5775 request body from its stdin but no reqest body is being written to
5776 the cgi. [Jeff Trawick]
5778 *) mod_log_config: %c connection status incorrectly logged
5779 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
5782 *) Get mod_cern_meta working under Windows
5785 *) Create Files, and thus MMAPs, out of the request pool, not the
5786 connection pool. This solves a small resource leak that had us
5787 not closing files until a connection was closed. In order to do
5788 this, at the end of the core_output_filter, we loop through the
5789 brigade and convert any data we have into a single HEAP bucket
5790 that we know will survive clearing the request_rec.
5791 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
5794 *) Completely revamp configure so that it preserves the standard make
5795 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
5796 the configure additions to EXTRA_* variables. Also, allow the user
5797 to specify NOTEST_* values for all of the above, which eliminates the
5798 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
5799 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
5800 avoid pointless duplications. Fix the order in which flags are given
5801 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
5802 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
5803 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
5804 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
5806 *) Get mod_tls to compile/work better on Windows. PR #7612
5807 [Bernhard Schrenk <b.schrenk improx.com>]
5809 *) Fix shutdown/restart hangs in the threaded MPM.
5810 [Jeff Trawick, Greg Ames, Ryan Bloom]
5812 *) Removed the keptalive boolean from conn_rec because it is now only
5813 used by a single routine and can be replaced by a local variable.
5814 [Greg Stein, Ryan Bloom, Roy Fielding]
5816 *) Patch prefork to put enough of the signal processing back in so that
5817 signals are all handled properly now. The previous patch fixed the
5818 deadlock race condition, but broke the user directed signal handling.
5819 This fixes it to work the way it did before my previous prefork patch
5820 (primarily, SIGTERM is now working).
5822 *) Change how input filters decide how much data is returned to the
5823 higher filter. We used to use a field in the conn_rec, with this
5824 change, we use an argument to ap_get_brigade to determine how much
5825 data is retrieved. [Ryan Bloom]
5827 *) Fix seg fault at start-up introduced by Ryan's change to enable
5828 modules to specify their own logging tags. mod_log_config
5829 registers an optional function, ap_register_log_handler().
5830 ap_register_log_handler() was being called by http_core before
5831 the directive hash table was created. This patch creates the
5832 directive hash table before ap_register_log_handler() is
5833 registered as an optional function.
5834 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
5836 *) Add ap_set_int_slot() function
5837 [John K. Sterling <sterling covalent.net>]
5839 *) Under certain circumstances, Apache did not supply the
5840 right response headers when requiring authentication.
5841 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
5842 (This is a port of the change that went into Apache 1.3.19.)
5844 *) Allow modules to specify their own logging tags. This basically
5845 allows a module to tell mod_log_config that when %x is encountered
5846 a specific function should be called. Currently, x can be any single
5847 character. It may be more useful to make this a string at some point.
5850 Changes with Apache 2.0.17
5852 *) If a higher-level filter handles the byterange aspects of a
5853 request, then the byterange filter should not try to redo the
5854 work. The most common case of this happening, is a byterange
5855 request going through the proxy, and the origin server handles
5856 the byterange request. The proxy should ignore it.
5857 [Graham Leggett <minfrin sharp.fm>]
5859 *) Changed the threaded mpm to have child_main join to each of the
5860 worker threads to make sure the kids are all gone before child_main
5861 exits after a signal (cleanup from perform_idle_server_maintenance).
5862 This is an extension of Ryans recent commit to make the child_main
5865 *) Add more options to the ap_mpm_query function. This also allows MPMs to
5866 report if their threads are dynamic or static. Finally, this also
5867 implements a new API, ap_show_mpm, which returns the MPM that was
5868 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
5870 *) Do not install the binaries from the support directory twice.
5871 [jun-ichiro hagino <itojun iijlab.net>]
5873 *) The ap_f* functions should flush data to the filter that is passed
5874 in, not the filter after the one passed in.
5875 [Ryan Morgan <rmorgan covalent.net>]
5877 *) Make ab work again by changing its native types to apr types and formats.
5878 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
5880 *) Move the byterange filter and all of the supporting functions back
5881 to the HTTP module. The byterange filter turned out to be very
5882 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
5884 *) Make clean, distclean, and extraclean consistently according to the
5885 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
5887 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
5888 This may have been causing problems stopping processes in the threaded
5891 *) Fix content-length in mod_negotiation to a long int representation.
5894 *) Remove BindAddress from the default config file.
5895 [<giles nemeton.com.au>]
5897 *) Allow module authors to add a module to their Apache build using
5898 --with-module, without re-running buildconf. The syntax is:
5899 --with-module=module_type:/path/to/module.c
5900 The configure script will copy the module.c file to
5901 modules/module_type, and it will be added to the relevant Makefiles.
5902 currently, this only works for static modules. [Ryan Bloom]
5904 *) Changes required to make prefork clean up idle children properly.
5905 There was a window during which a starting worker deadlocks when
5906 an idle cleanup arrives before it completes init. Apache then keeps
5907 trying to cleanup the same deadlocked worker forever (until higher
5908 pids come along, but it still will never reduce below the deadlocked
5909 pid). Thus the number of children would not reduce to the correct
5910 idle level. [Paul J. Reder]
5912 Changes with Apache 2.0.16
5914 *) Change the default installation directory to /usr/local/apache2,
5915 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
5917 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
5920 *) Get MaxRequestsPerChild working with the Windows MPM.
5923 *) Make generic hooks to work, with mod_generic_hook_import/export
5924 experimental modules. [Ben Laurie, Will Rowe]
5926 *) Fix segfaults for configuration file syntax errors such as
5927 "<Directory>" followed by "</Directory" and
5928 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
5930 *) Cleanup the --enable-layout option of configure. This makes
5931 us use a consistent location for the config.layout file, and it
5932 makes configure more portable.
5933 [jun-ichiro hagino <itojun iijlab.net>]
5935 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
5936 csv/gnuplot format, rudimentary ssl support and various other tweaks
5937 to make results more true to what is measured. The upshot of this it
5938 turns out that 'ab' has often underreported the true performance of
5939 apache. Often by a order of magnitude :-) See talk/paper of Sander
5940 Temme at April ApacheCon 2001 for details.
5941 [Dirk-Willem van Gulik]
5943 *) Clean up mod_cgid's temporary request pool. Besides fixing a
5944 storage leak this ensures that some unnecessary pipes are closed.
5947 *) Performance: Add quick_handler hook. This hook is called at the
5948 very beginning of the request processing before location_walk,
5949 translate_name, etc. This hook is useful for URI keyed content
5950 caches like Mike Abbott's Quick Shortcut Cache.
5953 *) top_module global variable renamed to ap_top_module [Perl]
5955 *) Move ap_set_last_modified to the core. This is a potentially
5956 controversial change, because this is kind of HTTP specific. However
5957 many protocols should be able to take advantage of this kind of
5958 information. I expect that headers will need one more layer of
5959 indirection for multi-protocol work, but this is a small step in
5960 the right direction. [Ryan Bloom]
5962 *) Enable mod_status by default. This matches what Apache 1.3 does.
5965 *) Add a ScriptSock directive to the default config file. This is
5966 only enabled when mod_cgid is used.
5967 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5969 Changes with Apache 2.0.15
5971 *) Untangled the buildconf script and eliminated the need for build's
5972 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
5973 libtool muck that is now under srclib/apr/build. [Roy Fielding]
5975 *) Win32: Don't accept more connections than we have worker threads
5979 *) Fix bug in the Unix threaded.c MPM that allowed child processes
5980 to fork() new child processes.
5983 *) SECURITY: Fix a major security problem with double-reverse lookup
5984 checking. Previously, a client connecting over IPv4 would not be
5985 matched properly when the server had an IPv6 listening socket.
5986 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
5988 *) Change the way the beos MPM handles polling to allow it to stop and
5989 restart. Problem was the sockets being polled were being reset by
5990 the select call, so once it had accepted a connection it was no
5991 longer listening on the UDP socket we use for shutdown instructions.
5992 APR needs to be altered, patch on it's way. [David Reid]
5994 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
5995 on error exit from ap_getline(). Some other code got upset because
5996 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
5998 *) Handle ap_discard_request_body() being called more than once.
5999 [Greg Ames, Jeff Trawick]
6001 *) Get rid of an inadvertent close of file descriptor 2 in
6002 mod_mime_magic. [Greg Ames, Jeff Trawick]
6004 *) Add a hook, create_request. This hook allows modules to modify
6005 a request while it is being created. This hook is called for all
6006 request_rec's, main request, sub request, and internal redirect.
6007 When this hook is called, the r->main, r->prev, r->next
6008 pointers have been set, so modules can determine what kind of
6009 request this is. [Ryan Bloom]
6011 *) Cleanup the build process a bit more. The Apache configure
6012 script no longer creates its own helper scripts, it just
6014 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
6016 *) Stop the forced downgrade of the connection to HTTP/1.0 for
6017 proxy requests. [Graham Leggett]
6019 *) Avoid using sscanf to determine the HTTP protocol number in
6020 the common case because sscanf is a performance hog. From
6021 Mike Abbot's Accelerating Apache patch number 6.
6022 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
6024 *) SECURITY: Fix a security exposure in mod_access. Previously when
6025 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
6026 were not evaluated properly (PR #7407). Also, add the ability to
6027 specify IPv6 address strings with optional prefix length on Allow
6028 and Deny. [Jeff Trawick]
6030 *) Enhance rotatelogs so that a UTC offset can be specified, and
6031 the logfile name can be formatted using strftime(3). (Brought
6032 forward from 1.3.) [Ken Coar]
6034 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
6035 DuplicateHandle on an IOCompletionPort (a practice which
6036 MS "discourages"). The new model does not rely on associating
6037 the completion port with the listening sockets, thus the
6038 completion port can be completely managed within the child
6039 process. A dedicated thread accepts connections off the network,
6040 then calls PostQueuedCompletionStatus() to wake up worker
6041 threads blocked on the completion port.
6044 *) Bring forward the --suexec-umask option which allows the
6045 builder to preset the umask for suexec processes. [Ken Coar]
6047 *) Add a -V flag to suexec, which causes it to display the
6048 compile-time settings with which it was built. (Only
6049 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
6051 *) Mod_include should always unset the content-length if the file is
6052 going to be passed through send_parsed_content. There is no to
6053 determine if the content will change before actually scanning the
6054 entire content. It is far safer to just remove the C-L as long
6055 as we are scanning it. [Ryan Bloom]
6057 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
6058 request and not Proxy-Authenticate.
6059 [Graham Leggett <minfrin sharp.fm>]
6061 Changes with Apache 2.0.14
6063 *) Fix content-length computation. We ONLY compute a content-length if
6064 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
6065 or we already have all the data. [Ryan Bloom]
6067 *) Report unbounded containers in the config file. Previously, a typo
6068 in the </container> directive could result in the rest of the config
6069 file being silently ignored, with undesired defaults used.
6072 *) Make the old_write filter use the ap_f* functions for the buffering.
6075 *) Move more code from the http module into the core server. This
6076 is core code, basically the default handler, the default input
6077 and output filters, and all of the core configuration directives.
6078 All of this code is required in order for the server to work, with or
6079 without HTTP. The server is closer to working without the HTTP
6080 module, although there is still more to do. [Ryan Bloom]
6082 *) Fix a number of SGI compile warnings throughout the server. Fix some
6083 bad parameters to apr_bucket_read(). Fix a bad statement in
6084 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
6085 consistently; we were mixing apr_time_t and time_t in invalid ways
6086 before. In load_file(), call apr_dso_error() instead of
6087 apr_strerror() so that we get a more specific string on some platforms.
6088 PR #6980 [Jeff Trawick]
6090 *) Allow modules to query the MPM about it's execution profile. This
6091 query API can and should be extended in the future, but for now,
6092 max_daemons, and threading or forking is a very good start.
6093 [Jon Travis <jtravis covalent.net>]
6095 *) Modify mod_include to send blocks of data no larger than 9k.
6096 Without this, mod_include will wait until the whole file is parsed,
6097 or the first tag is found to send any data to the client.
6098 [Paul J. Reder <rederpj raleigh.ibm.com>]
6100 *) Fix mod_info, so that <Directory> and <Location> directives are
6101 not displayed twice when displaying the current configuration.
6102 [Ryan Morgan <rmorgan covalent.net>]
6104 *) Add config directives to override DEFAULT_ERROR_MSG and
6105 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
6106 [Dan Rench <drench xnet.com>]
6108 *) Get mod_info building and loading on Win32. [William Rowe]
6110 *) Begin to move protocol independant functions out of mod_http. The goal
6111 is to have only functions that are HTTP specific in the http directory.
6114 Changes with Apache 2.0.13
6116 *) Don't assume that there will always be multiple calls to the byterange
6117 filter. It is possible that we will need to do byteranges with only
6118 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
6120 *) Move the error_bucket definition from the http module to the
6121 core server. Every protocol will need this ability, not just
6124 Changes with Apache 2.0.12
6126 *) Modify mod_file_cache to save pre-formatted strings for
6127 content-length and last-modified headers for performance.
6128 [Mike Abbot <mja trudge.engr.sgi.com>]
6130 *) Namespace protect IOBUFSIZ since it is exposed in the API.
6131 [Jon Travis <jtravis covalent.net>]
6133 *) Use "Basic" authentication instead of "basic" in ab, as the spec
6134 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
6136 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
6137 without ever filling it out. This fixes PR 7271.
6138 [Taketo Kabe <kabe sra-tohoku.co.jp> and
6139 Cliff Woolley <cliffwoolley yahoo.com>]
6141 *) Add a couple of GCC attribute tags to printf style functions.
6142 [Jon Travis <jtravis covalent.net>]
6144 *) Add the correct language tag for interoperation with the Taiwanese
6145 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
6147 *) Migrate the perchild MPM to use the new apr signal child, and
6148 APR thread functions. [Ryan Bloom]
6150 *) Close one copy of the CGI's stdout before creating the new process.
6151 The CGI will still have stdout, because we have already dup'ed it.
6152 This keeps Apache from waiting forever to send the results of a CGI
6153 process that has forked a long-lived child process.
6154 [Taketo Kabe <kabe sra-tohoku.co.jp>]
6156 *) Remove the rest of the pthreads functions from the threaded MPM.
6157 This requires the APR support for a signal thread that was just
6160 *) Make mod_dir use a fixup for sending a redirect to the browser.
6161 Before this, we were using a handler, which doesn't make much
6162 sense, because the handler wasn't generating any data, it would
6163 either return a redirect error code, or DECLINED. This fits the
6164 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
6166 *) Make the threaded MPM use APR threads instead of pthreads.
6169 *) Get mod_tls to the point where it actually appears to work in all cases.
6172 *) implement --enable-modules and --enable-mods-shared for "all" and
6173 "most". [Greg Stein]
6175 *) Move the threaded MPM to use APR locks instead of pthread locks.
6178 *) Rename mpmt_pthread to threaded. This is more in line with the
6179 fact that mpmt_pthread shouldn't be using pthreads directly, and
6180 it is a smaller name that doesn't tie into anything.
6183 *) Rename the module structures so that the exported symbol matches
6184 the file name, and it is easier to automate the installation
6185 process (generating LoadModule directives from the module filenames).
6188 *) Remove the coalesce filter. With the ap_f* functions, this filter
6189 is no longer needed. [Ryan Bloom]
6191 Changes with Apache 2.0.11
6193 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
6194 added feature of allowing a uid/gid per child process. If no
6195 uid/gid is specified, then Perchild behaves exactly like dexter.
6198 *) Get perchild building again. [Ryan Bloom]
6200 *) Don't disable threads just because we are using the prefork MPM.
6201 If somebody wants to compile without threads, they must now add
6202 --disable-threads to the configure command line. [Ryan Bloom]
6204 *) Begin to move the calls to update_child_status into common code, so
6205 that each individual MPM does not need to update the scoreboard itself.
6208 *) Allow mod_tls to compile under Unix boxes where openssl has been
6209 installed to the system include files.
6210 [Gomez Henri <new-httpd slib.fr>]
6212 *) Cleanup the mod_tls configure process. This should remove any need
6213 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
6214 configure doesn't check that yet. [Ryan Bloom]
6216 *) Add a very early prototype of SSL support (in mod_tls.c). It is
6217 vital that you read modules/tls/README before attempting to build
6220 *) Fix a potential seg fault on all platforms. David Reid fixed this
6221 on BEOS, but the problem could happen anywhere, so we don't want
6222 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
6224 *) Add new LogFormat directive, %D, to log time it takes to serve a
6225 request in microseconds. [Bill Stoddard]
6227 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
6228 SetOutputFilter. This corresponds nicely with the other Set
6229 directives, which operate on containers while the Add* directives
6230 tend to work directly on extensions. [Ryan Bloom]
6232 *) Cleanup the header handling a bit. This uses the apr_brigade_*
6233 functions for the buffering so that we don't need to compute
6234 the length of the headers before we actually create the header
6235 buffer. [Ryan Bloom]
6237 *) Allow filters to buffer data using the ap_f* functions. These have
6238 become macros that resolve directly to apr_brigade_*.
6241 *) Get the Unix MPM's to do a graceful restart again. If we are going
6242 to register a cleanup with ap_cleanup_scoreboard, then we have to
6243 kill the cleanup with the same function, and that function can't be
6244 static. [Ryan Bloom]
6246 *) Install all required header files. Without these, it was not
6247 possible to compile some modules outside of the server.
6250 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
6251 forward from 1.3 to 2.0, we missed a single line, which broke regex
6252 aliases. [Ryan Bloom]
6254 *) We have a poor abstraction in the protocol. This is a temporary
6255 hack to fix the bug, but it will need to be fixed for real. If
6256 we find an error while sending out a custom error response, we back
6257 up to the first non-OK request and send the data. Then, when we send
6258 the EOS from finalize_request_protocol, we go to the last request,
6259 to ensure that we aren't sending an EOS to a request that has already
6260 received one. Because the data is sent on a different request than
6261 the EOS, the error text never gets sent down the filter stack. This
6262 fixes the problem by finding the last request, and sending the data
6263 with that request. [Ryan Bloom]
6265 *) Make the server status page show the correct restart time, and
6266 thus the proper uptime. [Ryan Bloom]
6268 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
6269 should reduce the amount of duplicate code that is required to
6270 create CGI processes.
6271 [Paul J. Reder <rederpj raleigh.ibm.com>]
6273 *) ap_new_connection() closes the socket and returns NULL if a socket
6274 call fails. Usually this is due to a connection which has been
6275 reset. [Jeff Trawick]
6277 *) Move the Apache version information out of httpd.h and into release.h.
6278 This is in preparation for the first tag with the new tag and release
6279 system. [Ryan Bloom]
6281 *) Begin restructuring scoreboard code to enable adding back in
6282 the ability to use IPC other than shared memory.
6283 Get mod_status working on Windows again. [Bill Stoddard]
6285 *) Make mod_status work with 2.0. This will work for prefork,
6286 mpmt_pthread, and dexter. [Ryan Bloom]
6288 *) Correct a typo in httpd.conf.
6289 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
6291 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
6293 *) Get the correct IP address if ServerName isn't set and we can't
6294 find a fully-qualified domain name at startup.
6295 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
6297 *) Make mod_cgid work with SuExec. [Ryan Bloom]
6299 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
6300 'extra' stat's for user/group since they should never occur, and now
6301 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
6302 volumes. [William Rowe]
6304 *) Adopt apr features to simplify mod_includes. This changes the
6305 behavior of the USER_NAME variable, unknown uid's are now reported
6306 as USER_NAME="<unknown>" rather than the old user#000 result.
6307 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
6309 *) Adopt apr features for simplifing mod_userdir, and accept the new
6310 Win32/OS2 exceptions without hiccuping. [William Rowe]
6312 *) Replace configure --with-optim option by using and saving the
6313 environment variable OPTIM instead. This is needed because configure
6314 options do not support multiple flags separated by spaces.
6317 *) Fix some byterange handling. If we get a byte range that looks like
6318 "-999999" where that is past the end of the file, we should return
6319 a PARTIAL CONTENT status code, and return the whole file as one big
6320 byterange. This matches the 1.3 handling now. [Ryan Bloom]
6322 *) Make the error bucket a real meta-data bucket. This means that the
6323 bucket length is 0, and a read returns NULL data. If one of these
6324 buckets is passed down after the headers are sent, this data will
6325 just be ignored. [Greg Stein]
6327 *) The prefork MPM wasn't killing child processes correctly if a restart
6328 signal was received while the process was serving a request. The child
6329 process would become the equivalent of a second parent process. If
6330 we break out of the accept loop, then we need to do die after cleaning
6331 up after ourselves. [Ryan Bloom]
6333 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
6334 restarts. [Ryan Bloom]
6336 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
6337 the most optimal APR_FINFO_wanted bits. This spares Win32 from
6338 performing very expensive owner, group and permission lookups
6339 and allows the server to function until these apr_finfo_t fields
6340 are implemented under Win32. [William Rowe]
6342 *) Support for typedsafe optional functions - that is functions exported by
6343 optional modules, which, therefore, may or may not be present, depending
6344 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
6345 for sample code. [Ben Laurie]
6347 *) filters can now report an HTTP error to the server. This is done
6348 by sending a brigade where the first bucket is an error_bucket.
6349 This bucket is a simple bucket that stores an HTTP error and
6350 a string. Currently the string is not used, but it may be needed
6351 to output an error log. The http_header_filter will find this
6352 bucket, and output the error text, and then return
6353 AP_FILTER_ERROR, which informs the server that the error web page
6354 has already been sent. [Ryan Bloom]
6356 *) If we get an error, then we should remove all filters except for
6357 those critical to serving a web page. This fixes a bug, where
6358 error pages were going through the byterange filter, even though
6359 that made no sense. [Ryan Bloom]
6361 *) Relax the syntax checking of Host: headers in order to support
6362 iDNS. PR#6635 [Tony Finch]
6364 *) Cleanup the byterange filter to use the apr_brigade_partition
6365 and apr_bucket_copy functions. This removes a lot of very messy
6366 code, and hopefully makes this filter more stable.
6369 *) Remove AddModule and ClearModuleList directives. Both of these
6370 directives were used to ensure that modules could be enabled
6371 in the correct order. That requirement is now gone, because
6372 we use hooks to ensure that modules are in the correct order.
6375 *) When SuExec is specified, we need to add it to the list of
6376 targets to be built. If we don't, then any changes to the
6377 configuration won't affect SuExec, unless 'make suexec' is
6378 specifically run. [Ryan Bloom]
6380 *) Cleaned out open_file from mod_file_cache, as apr now accepts
6381 the APR_XTHREAD argument to open a file for consumption by
6382 parallel threads on win32. [William Rowe]
6384 *) Correct a bug in determining when we follow symlinks. The code
6385 expected a stat -1 result, not an apr_status_t positive error.
6386 Also check if the APR_FINFO_USER fields are valid before we
6387 follow the link. [William Rowe]
6389 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
6390 mpm_common.c. These functions are only valid on some platforms,
6391 so they should not be in the main-line code. [Ryan Bloom]
6393 *) Remove ap_chdir_file(). This function is not thread-safe,
6394 and nobody is currently using it. [Ryan Bloom]
6396 *) Do not try to run make depend if there are no .c files in the
6397 current directory, doing so makes `make depend` fail.
6400 *) Update highperformance.conf to work with either prefork or
6401 pthreads mpms. [Greg Ames]
6403 *) Stop checking to see if this is a pipelined request if we know
6404 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
6405 This keeps us from making an extra read call when serving a 1.0
6406 request. [Ryan Bloom and Greg Stein]
6408 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
6409 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
6410 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
6412 *) Fix the RFC number mentioned when complaining about a missing
6413 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
6415 *) Fix an endless loop in ab which occurred when ab was posting
6416 and the server dropped the connection unexpectedly.
6419 *) Fix a segfault while handling request bodies in ap_http_filter().
6420 This problem has been seen with mod_dav usage as well as with
6421 requests where the body was just being discarded. [Jeff Trawick]
6423 *) Some adjustment on the handling and automatic setting (via
6424 hints.m4) of various compilation flags (eg: CFLAGS). Also,
6425 add the capability to specify flags (NOTEST_CFLAGS and
6426 NOTEST_LDFLAGS) which are used to compile Apache, but
6427 not used during the configuration process. Useful for
6428 flags like "-Werror". [Jim Jagielski]
6430 *) Stop using environment variables to force debug mode or
6431 no detach. We now use the -D command line argument to
6432 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
6433 [Greg Stein, Ryan Bloom]
6435 *) Change handlers to use hooks. [Ben Laurie]
6437 *) Stop returning copies of filenames from both apr_file_t and
6438 apr_dir_t. We pstrdup the filenames that we store in the
6439 actual structures, so we don't need to pstrdup the strings again.
6442 *) mod_cgi: Fix some problems where the wrong error value was being
6443 traced. [Jeff Trawick]
6445 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
6448 *) Add generic hooks. [Ben Laurie]
6450 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
6452 *) Fix a segfault caused by mod_ext_filter when the external filter
6453 program does not exist. [Jeff Trawick]
6455 *) Fix an output truncation error when on an HTTP >= 1.0 request an
6456 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
6457 was served through mod_charset_lite (or anything else that would
6458 create a transient bucket in this size range). ap_bucket_make_heap()
6459 silently failed (fixed), transient_setaside() discovered it, but
6460 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
6462 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
6463 is that some browsers send extra lines at the end of POST requests, and
6464 we don't want to delay sending data back to the user just because the
6465 browser isn't well behaved. [Ryan Bloom]
6467 *) Get SuEXEC working again. We can't send absolute paths to suExec
6468 because it refuses to execute those programs. SuEXEC also wasn't
6469 always recognizing configuration changes made using the autoconf
6472 *) Allow the buildconf process to find the config.m4 files in the correct
6473 order. Basically, we can now name config.m4 files as config\d\d.m4,
6474 and we will sort them correctly when inserting them into the build
6475 process. [Ryan Bloom]
6477 *) Get mod_cgid to use apr calls for creating the actual CGI process.
6478 This also allows mod_cgid to use ap_os_create_priviledged_process,
6479 thus allowing for SuExec execution from mod_cgid. Currently, we do
6480 not support everything that standard SuExec supports, but at least
6481 it works minimally now. [Ryan Bloom]
6483 *) Allow SuExec to be configured from the ./configure command line.
6486 *) Update some of the docs in README and INSTALL to reflect some of
6487 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
6489 *) If we get EAGAIN returned from the call to apr_sendfile, then we
6490 need to call sendfile again. This gets us serving large files
6491 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
6493 *) Get the support programs building cleanly again.
6494 [Cliff Woolley <cliffwoolley yahoo.com>]
6496 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
6497 current directory logic now backs up over bin/ to determine the
6498 server root from the Apache.exe path.
6500 *) Apache/Win32 now follows the standard conventions of mod_foo.so
6501 loadable modules, dynamic libs are all named libfoo.dll, and the
6502 makefile.win populates the include, lib and libexec directories.
6504 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
6505 Apache gets IPv6 listening sockets by default. Additionally, the
6506 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
6507 numeric address strings (e.g., "Listen [fe80::1]:8080").
6510 *) Modify the install directory layout. Modules are now installed in
6511 modules/. Shared libraries should be installed in libraries/, but
6512 we don't have any of those on Unix yet. All install directories
6513 are modifyable at configure time. [Ryan Bloom]
6515 *) Install all header files in the same directory on Unix. [Ryan Bloom]
6517 *) Get the functions in server/linked into the server, regardless of
6518 which modules linked into the server. This uses the same hack
6519 for Apache that we use for APR and apr-util to ensure all of the
6520 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
6521 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
6522 the scripts a bit easier.
6525 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
6526 on the query, and remove IPv4 dependencies. [Jeff Trawick]
6528 *) Get all of the auth modules to the point that they will install and
6529 be loadable into the server. Our new build/install mechanism expects
6530 that all modules will have a common name format. The auth modules
6531 didn't use that format, so we didn't install them properly.
6534 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
6535 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
6537 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
6539 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
6540 after the end of the response. [Ryan Bloom]
6542 *) Get byterange requests working with responses that do not have a
6543 content-length. Because of the way byterange requests work, we have to
6544 have all of the data before we can actually do the byterange, so we
6545 can compute the content-length in the byterange filter.
6548 *) Get exe CGI's working again on Windows.
6551 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
6552 they keep track of whether or not their post config hook has been
6553 called before. Instead of a static variable (which is replaced when
6554 the DSO is loaded a second time), use userdata in the process pool.
6557 Changes with Apache 2.0a9
6559 *) Win32 now requires perl to complete the final install step for users
6560 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
6561 and installs the conf, htdocs and htdocs/manual directories.
6564 *) Make mod_include use a hash table to associate directive tags with
6565 functions. This allows modules to implement their own SSI tags easily.
6566 The idea is simple enough, a module can insert it's own tag and function
6567 combination into a hash table provided by mod_include. While mod_include
6568 parses an SSI file, when it encounters a tag in the file, it does a
6569 hash lookup to find the function that implements that tag, and passes
6570 all of the relevant data to the function. That function is then
6571 responsible for processing the tag and handing the remaining data back
6572 to mod_include for further processing.
6573 [Paul J. Reder <rederpj raleigh.ibm.com>]
6575 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
6576 fewer parameters: the local and remote socket addresses were removed
6577 from the parameter list because all required information is available
6578 via the APR socket. [Jeff Trawick]
6580 *) Distribution directory structure reorganized to reflect a
6581 normal source distribution with external install targets.
6584 *) The MPMs that need multiple segments of shared memory now create
6585 two apr_shmem_t variables, one for each shared memory allocation.
6586 the problem is that we can't determine how much memory will be required
6587 for shared memory allocations once we try to allocate more than one
6588 variable. The MM code automatically aligns the shared memory allocations,
6589 so we end up needing to pad the amount of shared memory we want based
6590 on how many variables will be allocated out of the shared memory segment.
6591 It is just easier to create a second apr_shmem_t variable, and two
6592 shmem memory blocks.
6595 *) Cleanup the export list a bit. This creates a single unified list of
6596 functions exported by APR. The export list is generated at configure
6597 time, and that list is then used to generate the exports.c file.
6598 Because of the way the export list is generated, we only export those
6599 functions that are valid on the platform we are building on.
6602 *) Enable logging the cookie with mod_log_config
6603 [Sander van Zoest <sander covalent.net>]
6605 *) Fix a segfault in mod_info when it reaches the end of the configuration.
6608 *) Added lib/aputil/ as a placeholder for utility functions which are not
6609 specific to the Apache HTTP Server (but do not make sense with APR).
6610 The first utility is "apu_dbm": a set of functions to work with DBM
6611 files. This first version can be compiled for SDBM or GDBM databases.
6614 *) Complete re-write of mod_include. This makes mod_include a filter that
6615 uses buckets directly. This has now served the FAQ correctly.
6616 [Paul Reder <rederpj raleigh.ibm.com>]
6618 *) Allow modules to specify the first filter in a sub_request when
6619 making the sub_request. This keeps modules from having to change the
6620 output_filter immediately after creating the sub-request, and therefore
6621 skip the sub_req_output_filter. [Ryan Bloom]
6623 *) Update ab to accept URLs with IPv6 literal address strings (in the
6624 format described in RFC 2732), and to build Host header fields in
6625 the same format. This allows IPv6 literal address strings to be
6626 used with ab. This support has been tested against Apache 1.3 with
6627 the KAME patch, but Apache 2.0 does not yet work with this format
6628 of the Host header field. [Jeff Trawick]
6630 *) Accomodate an out-of-space condition in the piped logs and the
6631 rotatelogs.c code, and no longer churn log processes for this
6632 condition. [Victor J. Orlikowski]
6634 *) Add support for partial writes with apr_sendfile() to core_output_filter.
6637 Changes with Apache 2.0a8
6639 *) Add a directive to mod_mime so that filters can be associated with
6643 *) Get multi-views working again. We were setting the path_info
6644 field incorrectly if we couldn't find the specified file.
6647 *) Fix 304 processing. The core should never try to send the headers
6648 down the filter stack. Always, just setup the table in the request
6649 record, and let the header filter convert it to data that is ready
6653 *) More fixes for the proxy. There are still bugs in the proxy code,
6654 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
6658 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
6661 *) APR: Add new apr_getopt_long function to handle long options.
6662 [B. W. Fitzpatrick <fitz red-bean.com>]
6664 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
6665 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
6666 hostname resolution/address string parsing and building
6667 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
6668 of one of the apr_sockaddr_t structures for a socket. Change
6669 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
6671 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
6672 I have proxied pages with it, cleanup will commence soon.
6675 *) Make the proxy work with filters. This isn't perfect, because we
6676 aren't dealing with the headers properly. [Ryan Bloom]
6678 *) Do not send a content-length iff the C-L is 0 and this is a head
6679 request. [Ryan Bloom]
6681 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
6682 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
6684 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
6686 *) Get the default_handler to stop trying to deal with HEAD requests.
6687 The idea is to let the content-length filter compute the C-L before
6688 we try to send the data. If we can get the C-L correctly, then we
6689 should send it in the HEAD response.
6692 *) The Header filter can now determine if a body should be sent based
6693 on r->header_only. The general idea of this is that if we delay
6694 deciding to send the body, then we might be able to compute the
6695 content-length correctly, which will help caching proxies to cache
6696 our data better. Any handler that doesn't want to try to compute
6697 the content-length can just send an EOS bucket without data and
6698 everything will just work.
6701 *) Add the referer to the error log if one is available.
6702 [Markus Gyger <mgyger itr.ch>]
6704 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
6705 change, the root of the configuration tree has been exposed to modules
6707 [Ryan Morgan <rmorgan covalent.net>]
6709 *) Get the core_output_filter to use the bucket interface directly.
6710 This keeps us from calling the content-length filter multiple times
6711 for a simple static request.
6714 *) We are sending the content-type correctly now.
6715 [Ryan Bloom and Will Rowe]
6717 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
6718 a bogus bytes-sent value when the only thing being sent was trailers
6719 and writev() returned an error (or EAGAIN). [Jeff Trawick]
6721 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
6722 hints file to determine which platforms define
6723 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
6726 *) APR: add apr_get_home_directory() [Jeff Trawick]
6728 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
6730 *) Not all platforms have INADDR_NONE defined by default. Apache
6731 used to make this check and define INADDR_NONE if appropriate,
6732 but APR needs the check too, and I suspect other applications will
6733 as well. APR now defines APR_INADDR_NONE, which is always a valid
6734 value on all platforms.
6735 [Branko Čibej <brane xbc.nu>]
6737 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
6738 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
6740 *) Relax the syntax checking of Host: headers in order to support
6741 iDNS. PR#6635 [Tony Finch]
6743 *) When reading from file buckets we convert to an MMAP if it makes
6744 sense. This also simplifies the default handler because the
6745 default handler no longer needs to try to create MMAPs.
6748 *) BUFF has been removed from the main server. The BUFF code will remain
6749 in the code until it has been purged from the proxy module as well.
6752 *) Byteranges have been completely re-written to be a filter. This
6753 has been tested, and I believe it is working correctly, but it could
6754 doesn't work for the Adobe Acrobat plug-in. The output almost matches
6755 the output from 1.3, the only difference being that 1.3 includes
6756 a content-length in the response, and this does not.
6759 *) APR read/write functions and bucket read functions now operate
6760 on unsigned integers, instead of signed ones. It doesn't make
6761 any sense to use signed ints, because we return the error codes,
6762 so if we have an error we should report 0 bytes read or written.
6765 *) Always compute the content length, whether it is sent or not.
6766 The reason for this, is that it allows us to correctly report
6767 the bytes_sent when logging the request. This also simplifies
6768 content-length filter a bit, and fixes the actual byte-reporing
6769 code in mod_log_config.c
6772 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
6773 it says, because it was only used by EOS and FLUSH buckets. Since
6774 neither of those are required at the end of a brigade, this was
6775 really signifying FLUSH_THE_DATA, but that can be determined better
6776 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
6777 buckets now return a length of 0, which is actually the amount of data
6778 read, so they make more sense.
6781 *) Allow the core_output_filter to save some data past the end of a
6782 request. If we get an EOS bucket, we only send the data if it
6783 makes sense to send it. This allows us to pipeline request
6784 responses. As a part of this, we also need to allocate mmap
6785 buckets out of the connection pool, not the request pool. This
6786 allows the mmap to outlive the request.
6789 *) Make blocking and non-blocking bucket reads work correctly for
6790 sockets and pipes. These are the only bucket types that should
6791 have non-blocking reads, because the other bucket types should
6792 ALWAYS be able to return something immediately.
6795 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
6796 server, but use Ctrl+Break to initiate a graceful restart
6797 instead of duplicating behavior. [John Sterling]
6799 *) Patch mod_autoindex to set the Last-Modified header based on
6800 the directory's mtime, and add the ETag header. [William Rowe]
6802 *) Merge the 1.3 patch to add support for logging query string in
6803 such a way that "%m %U%q %H" is the same as "%r".
6806 *) Port three log methods from mod_log_config 1.3 to 2.0:
6807 CLF compliant '-' byte count, method and protocol.
6810 *) Add a new LogFormat directive, %c, that will log connection
6811 status at the end of the response as follows:
6812 'X' - connection aborted before the response completed.
6813 '+' - connection may be kept-alive by the server.
6814 '-' - connection will be closed by the server.
6817 *) Expand APR for WinNT to fully accept and return utf-8 encoded
6818 Unicode file names and paths for Win32, and tag the Content-Type
6819 from mod_autoindex to reflect that charset if the feature
6820 macro APR_HAS_UNICODE_FS is true. [William Rowe]
6822 *) Compute the content length (and add appropriate header field) for
6823 the response when no content length is available and we can't use
6824 chunked encoding. [Jeff Trawick]
6826 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
6827 so that content input filters get dechunked data when using
6828 the default handler. Also removed REQUEST_CHUNKED_PASS.
6831 *) Add mod_ext_filter as an experimental module. This module allows
6832 the administrator to use external programs as filters. Currently,
6833 only filtering of output is supported. [Jeff Trawick]
6835 *) Most Apache functions work on EBCDIC machines again, as protocol
6836 data is now translated (again). [Jeff Trawick]
6838 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
6839 the EBCDIC support. They are noops on ASCII machines, so this
6840 type of translation doesn't have to be surrounded by #ifdef
6841 CHARSET_EBCDIC. [Jeff Trawick]
6843 *) Fix mod_include. tag commands work again, and the server will
6844 send the FAQ again. This also allows mod_include to set aside
6845 buckets that include partial buckets.
6846 [Ryan Bloom and David Reid]
6848 *) Add suexec support back. [Manoj Kasichainula]
6850 *) Lingering close now uses the socket directly instead of using
6851 BUFF. This has been tested, but since all we can tell is that it
6852 doesn't fail, this needs to be really hacked on.
6855 *) Allow filters to modify headers and have those headers be sent to
6856 the client. The idea is that we have an http_header filter that
6857 actually sends the headers to the network. This removes the need
6858 for the BUFF to send headers.
6861 *) Charset translation: mod_charset_lite handles translation of
6862 request bodies. Get rid of the xlate version of ap_md5_digest()
6863 since we don't compute digests of filtered (e.g., translated)
6864 response bodies this way anymore. (Note that we don't do it at
6865 all at the present; somebody needs to write a filter to do so.)
6868 *) Input filters and ap_get_brigade() now have a input mode parameter
6869 (blocking, non-blocking, peek) instead of a length parameter.
6872 *) Update the mime.types file to the registered media types as
6873 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
6876 *) Namespace protect some macros declared in ap_config.h
6879 *) Support HTTP header line folding with input filtering.
6882 *) Mod_include works again. This should still be re-written, but at
6883 least now we can serve an SHTML page again.
6886 *) Begin to remove BUFF from the core. Currently, we keep a pointer
6887 to both the BUFF and the socket in the conn_rec. Functions that
6888 want to use the BUFF can, functions that want to use the socket,
6889 can. They point to the same place.
6892 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
6893 [Tomas Ögren <stric ing.umu.se>]
6895 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
6896 associated pool goes away. (APR pipes on OS/2 were already had this
6897 logic.) This resolvs a fatal file descriptor leak with CGIs.
6900 *) The final line of the config file was not being read if there was
6901 no \n at the end of it. This was caused by apr_fgets returning
6902 APR_EOF even though we had read valid data. This is solved by
6903 making cfg_getline check the buff that was returned from apr_fgets.
6904 If apr_fgets return APR_EOF, but there was data in the buf, then we
6905 return the buf, otherwise we return NULL.
6908 *) Piped logs work again in the 2.0 series.
6911 *) Restore functionality broken by the mod_rewrite security fix:
6912 rewrite map lookup keys and default values are now expanded
6913 so that the lookup can depend on the requested URI etc.
6914 PR #6671 [Tony Finch]
6916 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
6917 security bug in some mass virtual hosting configurations
6918 that can allow a remote attacker to retrieve some files
6919 on the system that should be inaccessible. [Tony Finch]
6921 *) Add a pool bucket type. This bucket is used for data allocated out
6922 of a pool. If the pool is cleaned before the bucket is destroyed, then
6923 the data is converted to a heap bucket, allowing it to survive the
6927 *) Add a flush bucket. This allows modules to signal that the filters
6928 should all flush whatever data they currently have. There is no way
6929 to actually force them to do this, so if a filter ignores this bucket,
6930 that's life, but at least we can try with this.
6933 *) Add an output filter for sub-requests. This filter just strips the
6934 EOS bucket so that we don't confuse the main request's core output
6935 filter by sending multiple EOS buckets. This change also makes sub
6936 requests start to send EOS buckets when they are finished.
6939 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
6940 makes ap_bucket_destroy a return void, which is okay because it
6941 used to always return APR_SUCCESS, and nobody ever checked its
6942 return value anyway.
6943 [Cliff Woolley <cliffwoolley yahoo.com>]
6945 *) Remove the index into the bucket-type table from the buckets
6946 structure. This has now been replaced with a pointer to the
6947 bucket_type. Also add some macros to test the bucket-type.
6950 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
6951 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
6952 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
6953 All _VAR_ flavors changes to _DATA to be absolutely clear.
6956 *) Add support for /, //, //servername and //server/sharename
6957 parsing of <Directory> blocks under Win32 and OS2.
6958 [Tim Costello, William Rowe, Brian Harvard]
6960 *) Remove the function pointers from the ap_bucket type. They have been
6961 replaced with a global table. Modules are allowed to register bucket
6962 types and use then use those buckets.
6965 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
6966 once we finish writing the request body to the cgi child process;
6967 otherwise, the client doesn't hit EOF on stdin. Small request bodies
6968 worked without this change (for reasons I don't understand), but large
6969 ones didn't. [Jeff Trawick]
6971 *) Remove file bucket specific information from the ap_bucket type.
6972 This has been moved to a file_bucket specific type that hangs off
6973 the data pointer in the ap_bucket type.
6976 *) Input filtering now has a third argument. This is the amount of data
6977 to read from lower filters. This argument can be -1, 0, or a positive
6978 number. -1 means give me all the data you have, I'll deal with it and
6979 let you know if I need more. 0 means give me one line and one line
6980 only. A positive number means I want no more than this much data.
6982 Currently, only 0 and a positive number are implemented. This allows
6983 us to remove the remaining field from the conn_rec structure, which
6987 *) Big cleanup of the input filtering. The goal is that http_filter
6988 understands two conditions, headers and body. It knows where it is
6989 based on c->remaining. If c->remaining is 0, then we are in headers,
6990 and http_filter returns a line at a time. If it is not 0, then we are
6991 in body, and http_filter returns raw data, but only up to c->remaining
6992 bytes. It can return less, but never more.
6993 [Greg Ames, Ryan Bloom, Jeff Trawick]
6995 *) mod_cgi: Write all of the request body to the child, not just what
6996 the kernel would accept on the first write. [Jeff Trawick]
6998 *) Back out the change that moved the brigade from the core_output_filters
6999 ctx to the conn_rec. Since all requests over a given connection
7000 go through the same core_output_filter, the ctx pointer has the
7004 *) Fix another bug in the send_the_file() read/write loop. A partial
7005 send by apr_send would cause unsent data in the read buffer to
7006 get clobbered. Complete making send_the_file handle partial
7007 writes to the network.
7010 *) Fix a couple of type fixes to allow compilation on AIX again
7011 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
7013 *) Fix bug in send_the_file() which causes offset to be ignored
7014 if there are no headers to send.
7017 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
7018 filter. Useful for supporting Windows 9* with a binary
7019 compiled on Windows NT.
7022 Changes with Apache 2.0a7
7024 *) Reimplement core_output_filter to buffer/save bucket brigades
7025 across multiple calls to the core_filter. The brigade will be
7026 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
7027 thresholds are hit or the EOS bucket is received.
7030 *) Create experimental filter (buffer_filter) that coalesces bytes
7031 into one large buffer before invoking the next filter in the
7032 chain. This filter is particularly useful with the current
7033 implementation of mod_autoindex when it inserted above the
7034 chunk_filter. mod_autoindex generates a lot of brigades that
7035 containing buckets holding just a few bytes each. The
7036 buffer_filter coalesces these buckets into a single large bucket.
7039 *) Add apr_sendfile() support into the core_output_filter.
7042 *) Add apr_sendv() support into the core_output_filter.
7045 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
7046 [Mike Abbott <mja sgi.com>]
7048 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
7049 make much sense, because Apache uses buckets instead of BUFFs now.
7052 *) send_the_file now falls back to a read/write loop on platforms that
7053 do not have sendfile.
7054 [Ryan Bloom and Brian Havard]
7056 *) Install apachectl correctly, and substitute the proper values so
7057 that it works again. [Ryan Bloom]
7059 *) Better(??) handle platforms that lack sendfile().
7062 *) APR now has UUID generation/formatting/parsing support.
7065 *) Begin the http_filter. This is an input filter that understands
7066 the absolute basic amount required to parse an HTTP Request. The
7067 goal is to be able to split headers from request body before passing
7068 the data back to the other filters.
7071 *) Bring forward from 1.3.13 the config directory implementation
7074 *) install apxs if it is created
7077 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
7078 conversions. [William Rowe]
7080 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
7081 ap_add_output_filter(). [Jeff Trawick]
7083 *) Multiple build and configuration fixes
7086 -add datadir and localstatedir substitutions
7088 -fix logfilename misspelling
7089 -fix evaluation of installation dir variables and
7090 -replace $foobar by $(foobar) to be usefull in the makefile
7094 -add rules for cross-compiling in rules.mk. Okay, rule to check for
7095 $CC_FOR_BUILD is still missing
7096 -use CHECK_TOOL instead of CHECK_PROG for ranlib
7097 -add missing "AR=@AR@" to severaly Makefile.in's
7098 -cache result for "struct rlimit"
7099 -compile all helper programs with native and cross compiler
7100 and use the native version to generate header file
7101 [Rüdiger Kuhlmann <Tadu gmx.de>]
7103 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
7105 [Rüdiger Kuhlmann <Tadu gmx.de>]
7107 *) Fix a bug where a client which only sends \n to delimit header
7108 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
7109 message. Start working on ebcdic co-existance with input
7111 [William Rowe, Greg Ames]
7113 *) If mod_so is enabled in the server always create libexec, even
7114 if there are no modules installed in this directory. This is a
7115 requirement for APXS to work correctly.
7118 *) Connection oriented output filters are now stored in the
7119 conn_rec instead of the request_rec. This allows us to add the
7120 output filter in the pre-connection phase instead of the
7121 post_read_request phase, which keeps us from trying to write an
7122 error page before we have a filter to write to the network.
7123 [Ryan Bloom, Jeff Trawick, and Greg Ames]
7125 *) Cleaning up an mmap bucket no longer deletes the mmap. An
7126 mmap can be used across multiple buckets (default_handler with
7127 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
7128 the mmap itself can't be associated with the bucket.
7131 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
7134 *) Radical surgery to improve mod_isapi support under Win32.
7135 Includes a number of newer ServerSupportFunction calls, support
7136 for ReadClient (in order to retrieve POSTs greater than 48KB),
7137 and general bug fixes to more reliably load ISAPI .dll's and
7138 prevent leaking handle resources. Note: There are still
7139 discrepancies between IIS's and Apache's ServerVariables, and
7140 async calls are still not supported. Additional warnings are
7141 logged to facilitate debugging of unsupported ISAPI calls.
7144 *) Add input filtering to Apache. The basic idea for the input
7145 filters is the same as the ideas for output filters. The biggest
7146 difference is that instead of calling ap_pass_brigade, ap_get_brigade
7147 should be called, and the order of execution for the filter itself is
7148 different. When writing an output filter, a brigade is passed in,
7149 and filters operate directly on that brigade, when done, they call
7150 ap_pass_brigade. Input filters are the exact opposite. Because input
7151 is not a push operation, filters first call ap_get_brigade. When this
7152 function returns, the input filter will be left with a valid brigade.
7153 The input filter should then operate on the brigade, and return.
7156 *) Fix building on BSD/OS using its native make. The build system
7157 falls back to the BSD .include directive on that host platform.
7160 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
7161 SHA1 and plaintext password encodings. Make feature tests a
7162 bit more flexible. [William Rowe]
7164 *) Charset translation: mod_charset_lite handles output content
7165 translation in a filter. mod_charset_lite no longer ignores
7166 subrequests. A bunch of cruft related to BUFF's support for
7167 translating request and response bodies was removed.
7170 *) Move the addition of the CORE filter to the post_read_request
7171 hook in http_core.c. This removes the need to add the filter in
7172 multiple places and allows for an SSL module to be added much
7173 simpler. [Ryan Bloom]
7175 *) SECURITY: CVE-2000-0913 (cve.mitre.org)
7176 Fix a security problem that affects certain configurations of
7177 mod_rewrite. If the result of a RewriteRule is a filename that
7178 contains expansion specifiers, especially regexp backreferences
7179 $0..$9 and %0..%9, then it may be possible for an attacker to
7180 access any file on the web server. [Tony Finch]
7182 *) Fix a bug where errors that are detected during early request parsing
7183 don't produce visible HTTP error messages at the browser, because
7184 the core_filter wasn't present. [Greg Ames]
7186 *) Provide apr_socklen_t as a portability aid.
7187 [Victor J. Orlikowski]
7189 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
7190 as well as a comment arg to the add, adduser and update cmds.
7191 update allows the user to clear or preserve pw/groups/comment.
7192 Fixed a bug in dbmmanage that prevented the check option from
7193 parsing a password followed by :group... text. Corrected the
7194 seed calcualation for Win32 systems, and added -lsdbm support.
7197 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
7200 *) Avoid a segfault when parsing .htaccess files. An
7201 uninitialized tree pointer was passed to ap_build_config().
7204 *) Change the way that inet_addr & inet_network are checked for
7205 in APR's configure process to allow BeOS BONE to correctly
7206 find them. With this change BeOS BONE now builds from source
7207 with no problems. [David Reid]
7209 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
7210 the end of the parameters to execve() was stored in the wrong
7211 location, overlaying the storage beyond the newargs[] array and
7212 also passing uninitialized storage to execve(), which would
7213 sometimes fail with EFAULT. [Jeff Trawick]
7215 *) Fix a bug parsing configuration file containers. With a sequence
7216 like this in the config file
7218 <IfModule mod_kilroy.c>
7221 <IfModule mod_lovejoy.c>
7226 the second container would be terminated at the blank line due to
7227 sediment in the buffer from reading the prior </IfModule> and an
7228 error message would be generated for the real </IfModule> for the
7229 second container. Also due to this problem, any two characters
7230 could be used for "</" in the close of a container.
7233 *) ap_add_filter prototype changed to remove the ctx pointer. The
7234 pointer still remains in the filter structure, but it can not be
7235 a part of the ap_add_filter prototype. The reason is that when
7236 the core uses AddFilter to add a filter to the stack it doesn't
7237 know how to allocate the ctx pointer, or even how much memory should
7238 be allocated. The filters will have to be responsible for allocating
7239 the ctx memory when they need it.
7242 *) Add an AddFilter directive. This directive takes a list of filters
7243 that should be activated for the requested resource.
7246 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
7247 some other platforms). [Jeff Trawick]
7249 *) Modify mod_include to be a filter. Currently, it has only been tested
7250 on actual files, but it should work for CGI scripts too.
7253 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
7254 writes. apr_flush() for Unix: handle interrupted writes.
7257 *) NameVirtualHost can now take "*" as an argument instead of
7258 an IP address. This allows you to create a purely name-based
7259 virtual hosting server that does not have any IP addresses in
7260 the configuration file and which ignores the local address
7261 of any connections. PR #5595, PR #4455 [Tony Finch]
7263 *) Fix some compile warnings in mod_mmap_static.c
7264 [Mike Abbott <mja sgi.com>]
7266 *) Fix chunking problem with CGI scripts. The general problem was that
7267 the CGI modules were adding an EOS bucket and then the core added an
7268 EOS bucket. The chunking filter finalizes the chunked response when it
7269 encounters an EOS bucket. Because two EOS buckets were sent, we
7270 finalized the response twice. The fix is to make sure we only send one
7271 EOS, by utilizing a flag in the request_rec.
7274 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
7275 and Win32. Previously, the first read from an apr_file_t set up via
7276 apr_put_os_file() would return a '\0'. [Jeff Trawick]
7278 *) Mod_cgid now creates a single element bucket brigade, with a pipe
7279 bucket, instead of using BUFF's and ap_r*.
7282 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
7283 [Mike Abbott <mja sgi.com>]
7285 *) Remove ap_bopenf from buff code. This required modifying the file_cache
7286 code to use APR file's directly instead of going through BUFFs.
7289 *) Fix compile break on some platforms for mod_mime_magic.c
7290 [John K. Sterling <sterling covalent.net>]
7292 *) Fix merging of AddDefaultCharset directive.
7293 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
7295 *) Minor revamp of the rlimit sections of code. We now test
7296 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
7297 is now "available" even if the platform doesn't support
7298 the rlimit family (it's just a noop though). [Jim Jagielski]
7300 *) Migrate the pre-selection of which MPM to use for specific
7301 platforms to hints.m4, which contains (or should contain)
7302 all platform specific "hints". [Jim Jagielski]
7304 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
7307 *) Add tables with non-string/binary values to APR.
7310 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
7313 *) Update PCRE to version 3.2. [Ryan Bloom]
7315 *) Change the way buckets' destroy functions are called so that
7316 they can be more directly used when changing the type of a
7317 bucket in place. [Tony Finch]
7319 *) Add generic support for reference-counting the resources used by
7320 buckets, and alter the HEAP and MMAP buckets to use it. Change
7321 the way buckets are initialised to support changing the type of
7322 buckets in place, and use it when setting aside TRANSIENT buckets.
7323 Change the implementation of TRANSIENT buckets so that it can be
7324 mostly shared with IMMORTAL buckets, which are now implemented.
7327 Changes with Apache 2.0a6
7329 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
7331 *) Add a chunking filter to Apache. This brings us one step closer
7332 to removing BUFF. [Ryan Bloom]
7334 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
7335 added to the stack is the last filter to be called. [Ryan Bloom]
7337 *) Apache 2.0 has been completely documented using Scandoc. The
7338 docs can be generated by running 'make docs'. [Ryan Bloom]
7340 *) Add filtered I/O to Apache. This is based on bucket brigades,
7341 Currently the buckets still use BUFF under the covers, but that
7342 should change quickly. The only currently written filter is the
7343 core filter which just calls ap_bwrite. [The Apache Group]
7345 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
7346 built with thread support. [Jeff Trawick]
7348 *) Abort configuration if --with-layout was specified and there's
7349 no layout definition file. [Ken Coar]
7351 *) Add support for '--with-port=n' option to configure. [Ken Coar]
7353 *) Add support for extension methods for the Allow response header
7354 field, and an API routine for accessing r->allowed and the
7355 list of extension methods in a unified manner. [Ken Coar]
7357 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
7358 [Rob Simonson <simo us.ibm.com>]
7360 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
7361 APACHE_XLATE builds. [Jeff Trawick]
7363 *) A configuration file parsing problem was fixed. When the
7364 configuration file started with an IfModule/IfDefine container,
7365 only the last statement in the container would be retained.
7368 Changes with Apache 2.0a5
7370 *) Perchild is serving pages after passing them to different child
7371 processes. There are still a lot of bugs, but this does work. I
7372 have made requests against the same installation of Apache, and had
7373 different servers use different user IDs to serve the responses.
7374 This change moves to using socketpair instead of an AF_UNIX socket.
7377 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
7378 It can't seem to pass between child processes yet, but I think we
7379 are closer now than before. This moves us back to using Unix
7380 Domain Sockets. [Ryan Bloom]
7382 *) libapr functions and types renamed with apr_ prefix.
7383 #include "apr_compat.h" for 1.3.x backwards compat
7386 *) Fix problems with APR sockaddr handling on Win32. It didn't always
7387 return the right information on the local socket address.
7388 [Gregory Nicholls <gnicholls level8.com>]
7390 *) ap_recv() on Win32: Set bytes-read to 0 on error.
7391 [Gregory Nicholls <gnicholls level8.com>]
7393 *) Add an option to not detach from the controlling terminal without
7394 going into single process mode. This allows for much easier
7395 debugging of the process startup code. [Ryan Bloom]
7397 *) ab: don't use perror() to report the failure of an APR function.
7400 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
7401 scoreboard on graceful restarts.
7404 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
7405 An invalid ap_proc_t was passed to ap_create_process().
7408 *) Allow modules to register filters. Those filters are still
7409 never called, but this is a step in the right direction.
7410 [Ryan Bloom and Greg Stein]
7412 *) Register the mod_cgid daemon process for cleanup so that it is
7413 killed at termination if it does not die when the parent gets
7414 SIGTERM. This change is to fix occasional problems where the
7415 process stays around. Bugs in similar logic in mod_rewrite and
7416 mod_include were also fixed. [Jeff Trawick]
7418 *) Fix a bug in the time handling. Basically, we were imploding a time
7419 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
7420 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
7421 uses those two fields to adjust the time value. Because of the HTTP
7422 spec, both of those values can be zero'ed out safely. This fixes
7423 the bug correctly. [Ryan Bloom]
7425 *) Fix a couple of place in the Windows code where the wrong error
7426 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
7428 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
7430 *) Added the APR_EOL_STR macro for platform dependent differences in
7431 logfiles and other raw text (such as all APR files). Fixes logfiles
7432 not terminated with cr/lf sequences in Win32. [William Rowe]
7434 *) Move all strings functions in APR to src/lib/apr/strings and create
7435 apr_strings.h for the prototypes. [Ryan Bloom]
7437 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
7438 to repeat the syscall until we stop getting EINTR. I noticed a
7439 related problem at termination (SIGTERM) on FreeBSD when using
7440 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
7441 implementation work properly with child init. Previously, ap_lock()
7442 was essentially a no-op because all children were using different
7443 locks and thus nobody ever blocked. [Jeff Trawick]
7445 *) The htdocs/ tree has been moved out of the CVS source tree into
7446 a separate area for easier development. This has NO EFFECT on
7447 end-users or Apache installations. [Ken Coar]
7449 *) Integrate the mod_dav module for WebDAV protocol handling. This
7450 adds the dav and dav_fs modules, the SDBM library, and additional
7451 XML handling utilities. [Greg Stein]
7453 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
7456 *) Update the lib/expat-lite/ library (bring forward changes from
7457 the Apache 1.3 repository). [Greg Stein]
7459 *) If sizeof(long long) == sizeof(long), then prefer long in APR
7460 configure.in. [Dave Hill <ddhill zk3.dec.com>]
7462 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
7463 machines where sendfile is detected, but nobody has written ap_sendfile.
7464 [Dave Hill <ddhill zk3.dec.com>]
7466 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
7468 *) ab would start up more connections than needed, then quit when the
7469 desired number were finished. Also fixed a logic error involving
7470 ab keepalives. [Victor J. Orlikowski]
7472 *) WinNT: Implement non-blocking pipes with timeouts to communicate
7473 with CGIs. Apache 2.0a4 had non-blocking pipes but without
7474 timeouts (i.e, if a timeout was specified, the pipe reverted to
7475 a full blocking pipe). Now the behaviour is more in line with
7476 Unix non-blocking pipes.
7479 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
7480 cache open file handles along with accept socket reuse enables
7481 Apache 2.0 to serve non-keepalive requests for static files at
7482 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
7483 and Apache 2.0 will serve almost 1200 rps on my system).
7486 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
7487 supports two config directives, mmapfile (same behavious as
7488 mod_mmap_static) and cachefile. Use the cachefile directive
7489 to cache open file handles. This directive only works on systems
7490 that have implemented the ap_sendfile API. cachefile works today
7491 on Windows NT, but has not been tested on any flavors of Unix.
7494 *) Cleanup the configuration. With the last few changes the
7495 configuration process automatically:
7496 inherits information about how to build from APR. Allowing
7497 APR to inform Apache that it should or should not use -ldl
7499 Detects which mod_cgi should be used mod_cgi or mod_cgid,
7500 based on the threading model
7502 Apache calls APR's configure process before finishing it's
7503 configuration processing, allowing for more information flow
7508 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
7509 with non-zero argument makes the socket non-blocking. BeOS and
7510 OS/2 already worked this way. [Jeff Trawick]
7512 *) ap_close() now calls ap_flush() for buffered files, so write
7513 operations work a whole lot better on buffered files.
7516 *) Fix error messages issued from MPMs which explain where to change
7517 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
7520 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
7521 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
7522 now the way that the blocking state of a pipe is manipulated.
7523 ap_block_pipe() is gone. [Jeff Trawick]
7525 *) Correct the problem where the only local host name that the IP stack
7526 can discover are 'undotted' private names. If no fully qualified
7527 domain name can be identified, the default ServerName will be set to
7528 the machine's IP address string. A warning is always provided if the
7529 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
7531 *) Repair problems with config file processing which caused segfault
7532 at init when virtual hosts were defined and which caused ServerName to
7533 be ignored when there was no valid DNS setup. [Jeff Trawick]
7535 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
7537 *) Add ap_sendfile implementation for AIX
7538 [Victor J. Orlikowski]
7540 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
7541 apr_network_io.h, and apr_thread_proc.h.
7542 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
7544 *) Bring the allocation and pool debugging code back into a working
7545 state. This will need to be tested as so far it's only been used on
7548 *) Change configuration command setup to be properly typesafe when in
7549 maintainer mode. Note that this requires a compiler that can initialise
7550 unions. [Ben Laurie]
7552 *) Turn on buffering for config file reads. Part of this was to
7553 repair buffered I/O support in Unix and implement buffered
7554 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
7556 *) Win32: Fix problem where UTC offset was not being set correctly
7557 in the access log. Problem reported on news group by Jerry Baker.
7560 *) Fix segfault when reporting this type of syntax error:
7561 "</container> without matching <container> section", where
7562 container is VirtualHost or Directory or whatever.
7565 *) SECURITY: CVE-2000-1204 (cve.mitre.org)
7566 Prevent the source code for CGIs from being revealed when
7567 using mod_vhost_alias and the CGI directory is under the document root
7568 and a user makes a request like http://www.example.com//cgi-bin/cgi
7569 as reported in <news:960999105.344321 ernani.logica.co.uk>
7572 *) Add support for the new Beos NetwOrking Environment (BONE)
7575 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
7576 final input char is incomplete; ap_bwrite_xlate() now handles
7577 incomplete final input chars. [Jeff Trawick]
7579 *) Yet another update to saferead/halfduplex stuff -- need to ensure
7580 that a bhalfduplex call occurs before logging or else DNS and
7581 such can delay the last packet of the response. [Dean Gaudet]
7583 *) Some syscall reduction in APR on unix -- don't seek when setting
7584 up an mmap; and don't fcntl() more than once per socket.
7587 *) When mod_cgid is started as root, the cgi daemon now switches
7588 to the configured User/Group (like other httpd processes)
7589 instead of continuing as root. [Jeff Trawick]
7591 *) The prefork MPM now uses an APR lock for the accept() mutex.
7592 It has not been getting a lock at all recently. httpd -V now
7593 displays APR's selection of the lock mechanism instead of the
7594 symbols previously respected by prefork. [Jeff Trawick]
7596 *) Change the mmap() feature test to check only for existence.
7597 The previous check required features not used by Apache.
7600 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
7601 sometimes mangled. The len parm to accept() was not
7602 initialized, leading sometimes to an endless loop of failed
7603 accept() calls on OS/390 and anywhere else that failed the call
7604 if the len was negative. Use <sys/un.h> for struct sockaddr_un
7605 instead of declaring it ourselves to fix a compilation problem
7606 on Solaris. [Jeff Trawick]
7608 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
7610 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
7612 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
7614 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
7615 initialization if ALLOC_DEBUG is defined; no known symptom
7616 otherwise. [Jeff Trawick]
7618 *) Fix typo in configure script when checking for mod_so. bash
7619 doesn't seem to have a problem but /bin/sh on Solaris does.
7620 Symptom: "./configure: test: unknown operator =="
7623 *) Rebind the Win32 NT and 9x services control into the MPM.
7624 All console, WinNT SCM and Win9x pseudo-service control code is
7625 now wrapped within the WinNT MPM.
7628 *) Make a copy of getenv("PATH") before storing for later use. Some
7629 getenv() implementations use the same storage for successive calls.
7630 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
7632 *) Server Tokens work in 2.0 again. This also propogates the change
7633 to allow just the product name in the server string using
7637 Changes with Apache 2.0a4
7639 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
7640 won't need to call it. [Greg Ames, Jeff Trawick]
7642 *) Move pre_config hook call to between configuration read and config
7643 tree walk. This allows all modules to implement pre_config hooks
7644 and know that they will be called at an appropriate time.
7647 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
7650 *) Add pre-config hooks back to all modules.
7653 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
7654 ContentDigest enabled and we can't/don't mmap the file.
7657 *) We now report the correct line number for syntax errors in config
7658 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
7660 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
7661 related bugs, and changed shmem/locking to use apr API. Shared-mem
7662 is currently disabled, however, because of problems with graceful
7663 restarts. [Ronald Tschalär]
7665 *) Fix corruption of IFS variable in --with-module= handling.
7666 Depending on the user's shell or customization thereof, there
7667 would be errors generating ap_config_auto.h later in the configure
7668 procedure. [Jeff Trawick]
7670 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
7671 isn't used (as in 1.3), except that on Unix it is now logged via
7672 ap_log_rerror() instead of by the child having STDERR_FILENO refer
7673 to the error log. [Greg Ames, Jeff Trawick]
7675 *) Add '-D' argument processing for run time configuration defines.
7678 *) Organize http_main.c as independent code, such that no code or
7679 global data is exported from it. WIN32 will dynamically link it
7680 to the server core, so this will prevent mutual dependency.
7683 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
7684 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
7687 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
7688 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
7690 *) Add mod_charset_lite for configuring character set translation.
7693 *) Add '-n' option to htpasswd to make it print its user:pw record
7694 on stdout rather than having to frob a text file. [Ken Coar]
7696 *) Fix saferead. Basically, we flush the output buffer if a read on the
7700 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
7701 a conversion is single-byte only. [Jeff Trawick]
7703 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
7704 the BeOS 5.0 documentation says that shutdown doesn't work yet.
7707 *) Fix some minor errors where pid was being manipulated as an int
7708 instead of the portable pid_t. [Roy Fielding]
7710 *) Fix some error log prints that were printing the pointer to a
7711 structure rather than the pid within the structure.
7712 [Jeff Trawick, Roy Fielding]
7714 *) ab: Fix a command-line processing bug; track bad headers in
7715 err_response; support reading headers up to 2K.
7716 [Ask Bjoern Hansen <ask valueclick.com>]
7718 *) Fix ap_resolve_env() so that it handles new function added in a prior
7719 alpha (see "Added the capability to do ${ENVVAR} constructs in the
7720 config file.") as well as the constructs used by mod_rewrite.
7721 [Paul Reder <rederpj raleigh.ibm.com>]
7723 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
7725 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
7726 APR to perform translation, instead of accessing the hard-coded tables
7727 in 1.3's ebcdic.c. [Jeff Trawick]
7729 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
7732 *) Add the ability to hook into the config file reading phase. Basically
7733 if a directive is specified EXEC_ON_READ, then when that directive is
7734 read from the config file, the assocaited function is executed. This
7735 should only be used for those directives that must muck with HOW the
7736 server INTERPRETS the config. This should not be used for directives
7737 that re-order or replace items in the config tree. Those changes should
7738 be made in the pre-config step.
7741 *) Add mod_example to the build system.
7744 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
7745 byte character sets. [Jeff Trawick]
7747 *) Pick up various EBCDIC fixes from 1.3 (from Martin
7748 Kraemer and Oliver Reh originally according to the change log).
7751 *) Fix a couple of problems in RFC1413 support (controlled by the
7752 IdentityCheck directive). Apache did not build the request string
7753 properly and more importantly Apache would loop forever if the
7754 would-be ident server dropped the connection before sending a
7755 properly terminated response. [Jeff Trawick]
7757 *) apxs works in 2.0.
7760 *) Reliable piped logs work in 2.0.
7763 *) Introduce a hash table implementation into APR to be used for
7764 replacing tables and other random data structures in Apache.
7767 *) Add some more error reporting to htpasswd in the case of problems
7768 generating or accessing the temporary file. Also, pass in a
7769 buffer if the implementation knows how to use it (i.e., if L_tmpnam
7770 is defined). [Ken Coar]
7772 *) Configure creates config.nice now containing your configure
7773 options. Syntax: ./config.nice [--more-options]
7776 *) Fix various return code problems in APR on Win32. For most of
7777 these, APR was returning APR_EEXIST instead of GetLastError()/
7778 WSAGetLastError(). [Jeff Trawick]
7780 *) Make piped logs work again in version 2.0
7783 *) Add VPATH support to UNIX build system of Apache and APR.
7786 *) Fix ap_tokenize_to_argv to respect the const arguments that are
7790 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
7791 Patch submitted to author.
7794 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
7795 /sbin in PATH on FreeBSD (all submitted to rse previously)
7798 *) Fix building Pthread-based MPMs on OpenBSD
7799 [Sascha Schumann] PR#26
7801 *) Fix ap_readdir() problem on systems where d_name[] field in
7802 struct dirent is declared with only one byte. (This problem only
7803 affected multithreaded builds.) This caused a segfault during
7804 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
7805 least). [Jeff Trawick]
7807 *) Fix some make-portability problems on at least Tru64, Irix
7809 [Sascha Schumann] PR#18, PR#39
7811 *) Add ap_sigwait() to support old-style sigwait() on systems
7812 like OS/390 and UnixWare.
7815 *) Add POSIX-thread flags for more platforms.
7818 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
7819 (on Unix, at least) to handle resolver errors. Fix a bug in
7820 the definition of APR_ENOMEM so that ap_strerror() can spit
7821 out the correct error message for it.
7824 Changes with Apache 2.0a3
7826 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
7829 *) API: *HOOK* macros now have an AP_ prefix
7832 *) Win32: Eliminate redundant calls to initialize winsock.
7833 [Tim Costello <timcostello ozemail.com.au>]
7835 *) Fix bugs initializing ungetchar for pipes.
7836 [Chia-liang Kao <clkao CirX.ORG>]
7838 *) The ab program in the src/support directory is now portable using
7842 *) Support directory is being compiled when the server is built
7845 *) The configure option --with-program-name has been added to allow
7846 developers to rename the executable at configure time. This also
7847 changes the name of the config files to match the executable's name.
7850 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
7851 containing version numbers. [Martin Pool]
7853 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
7854 Unix; access_log and error_log now created with these perms; non-
7855 Unix is unaffected [Jeff Trawick]
7857 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
7858 Replaced more magic numbers with MD5_DIGESTSIZE.
7859 [William Rowe, Roy Fielding]
7861 *) Win32: Get mod_auth_digest compiling and added to the Windows
7862 build environment. Not tested and I'd be suprised if it
7863 actually works. [Bill Stoddard]
7865 *) Revamp the Win32 make environment. Makefiles have been removed and
7866 Apache.dsw created to bring together all the pieces. Create new file
7867 os/win32/BaseAddr.ref to define module base addresses (to prevent
7868 dll relocation at start-up).
7869 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
7871 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
7872 of the \015, \012, and \015\012 constants with macros.
7875 *) Add ap_xlate_open() et al for translation of text between different
7876 character sets. The initial implementation requires iconv().
7879 *) More FAQs and answers from comp.infosystems.www.servers.unix.
7880 [Joshua Slive <slive finance.commerce.ubc.ca>]
7882 *) CGI output is being timed out now.
7885 *) Fix the problem with dieing quietly. dupfile now takes a pool which
7886 is used by the new apr file. There is no reason to create a new file
7887 with the same lifetime as the original file.
7890 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
7891 module base addresses. This will help shooting seg faults
7892 in the field. [William Rowe <wrowe lnd.com>]
7894 *) Update Apache on Windows documentation. Add new document
7895 describing how to compile Apache on Windows.
7896 [William Rowe <wrowe lnd.com>]
7898 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
7899 microseconds instead of seconds. Some storage leaks and other
7900 minor bugs in related code were fixed. [Jeff Trawick]
7902 *) Win32: First cut at getting mod_isapi working under 2.0
7903 [William Rowe <wrowe lnd.com>]
7905 *) First stab at getting mod_auth_digest working under 2.0
7906 quick change summary:
7907 - moved the random byte generation (ap_generate_random_bytes) into APR
7908 - now uses ap_time_t
7909 - compiles and runs on linux
7911 [Brian Martin <bmartin penguincomputing.com>]
7913 *) Win32: Move the space stripping of physical service names
7914 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
7915 unresolved symbol. Add dependency checking to the
7916 CreateService call to ensure TCPIP and AFP (winsock) is started
7918 [William Rowe <wrowe lnd.com>]
7920 *) Win32: Add code to perform latebinding on functions that may
7921 not exist on all levels of Windows where Apache runs. This
7922 is needed to allow Apache to start-up on Win95/98. All calls
7923 to non portable functions should be protected with
7924 ap_oslevel checks to prevent runtime segfaults.
7925 [William Rowe <wrowe lnd.com>]
7927 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
7929 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
7931 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
7932 This addresses PR 1623. Still need to address timing out runaway
7933 CGI scripts. [Bill Stoddard]
7935 *) Win32: Make ap_stat Windows 95/98 friendly
7936 [William Rowe <wrowe lnd.com>]
7938 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
7939 always fail. Need to initialise the dwOSVersionInfoSize member of the
7940 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
7943 The patch also enhances ap_get_oslevel (and the associated enum) to
7944 handle selected service packs for NT4, and adds recognition for
7945 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
7946 we can use ReadFileScatter and WriteFileGather in readwrite.c.
7947 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
7949 *) Get mod_rewrite building and running, and mod_status building for Win NT
7950 [Allan Edwards <ake raleigh.ibm.com>]
7952 *) Patch to port mod_auth_db to the 2.0 api and also to support
7953 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
7954 2.7.7. It should work with version 1 as well but I haven't tested it.
7955 [Brian Martin <bmartin penguincomputing.com>]
7957 *) Get APR DSO code working under Windows. Includes cross platform
7959 [<Tim.Costello BTFinancialgroup.com>]
7961 *) Fix some of the Windows APR time functions.
7964 *) FAQ changes related to tidying up historical documents on the web site.
7965 [Joshua Slive <slive finance.commerce.ubc.ca>]
7967 *) Move Windows DSO code into APR.
7970 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
7971 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
7972 at build time. At this point, the server will not compile on Windows because
7973 of the recent DSO commits. Fixing those next.
7974 [Bill Rowe & Bill Stoddard]
7976 *) Added error checking for file I/O APR routines.
7977 [Jon Travis <jtravis covalent.net>]
7979 *) APR: Don't use the values of resolver error codes for the
7980 corresponding APR error codes. On Unix and Win32, return the
7981 proper APR error code after a resolver error. [Jeff Trawick]
7983 Changes with Apache 2.0a2
7985 *) Renamed the executable back to httpd on all platforms other
7989 *) Allow BeOS to survive restarts, log properly and a few
7990 small things it had problems with due to the way it setup
7991 users and groups. [David Reid]
7993 *) Get mod_rewrite working with APR locks
7994 [Paul Reder <rederpj raleigh.ibm.com>]
7996 *) Actually remove the sempahore when the lock cleanup routine
7997 is called on BeOS. [David Reid]
7999 *) Clear hook registrations between reads of the config file.
8000 When DSOs are unloaded and re-loaded the old hook pointers may
8001 no longer be valid. This fix eliminates potential segfaults.
8002 [Allan Edwards <ake raleigh.ibm.com>]
8004 *) Fix a problem with Sigfunc not being defined or bypassed
8005 if sigaction() wasn't found. [Jim Jagielski]
8007 *) Fix the locking mechanism on BSD variants. They now use fcntl
8008 locks. This allows the server to start and serve pages.
8011 *) First cut at getting the Win32 installer to work
8012 [William Rowe <wrowe lnd.com>]
8014 *) Get htpasswd compiling under Windows
8015 [William Rowe <wrowe lnd.com>]
8017 *) Change the log message for a bind() failure to show the
8018 interface and port number. [Jeff Trawick]
8020 *) Import the documentation from 1.3.12 and bring parts of it
8021 up-to-date with respect to the changes that have occurred
8025 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
8026 now logged correctly on BeOS.
8029 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
8030 Makefile.win includes the same user interface as the old
8032 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
8034 *) Win32 exec now uses COMSPEC environment string for command
8035 shell path resolution.
8036 [William Rowe <wrowe lnd.com>] PR#3715
8038 *) Win32: ap_connect() was not returning correct error condition
8040 [Allen Prescott <allen clanprescott.com>]
8042 *) Win32: ap_open() was broken on Win9x because an NT-specific
8043 flag was passed to CreateFile. ap_puts() added an unnecessary
8045 [Jeff Trawick <trawick us.ibm.com>]
8047 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
8048 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
8049 confusing ee/et name and made all extensions language/dialect
8050 rather than country reflecting. Changed example files to
8051 explicit reflect the ISO charset and added a few common
8052 ones to the example config [dirkx]
8054 *) Extend external module capability. To use this, you call
8055 configure with --with-module=path/to/mod1,path/to/mod2,etc.
8058 *) Backported the various "default charset" fixes from 1.3.12,
8059 including the AddDefaultCharset directive. [Jim Jagielski]
8061 *) Added the capability to do ${ENVVAR} constructs in the
8062 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
8063 it does this on a line by line basis; i.e. if the envvar
8064 expands to something with spaces you have to protect it
8065 by adding quotes around it (Unless of course you expect it
8066 to contains more than one argument. Alternatively you
8067 can compile it on a per token basis; which is what people
8068 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
8069 hampers fancier hacks.
8070 [Dirk-Willem van Gulik]
8072 *) Changed the 'ErrorDocument' syntax in that it NO longer
8073 supports the asymetric
8075 ErrorDocument 301 "Some message
8077 Note the opening " quote, without a closing quote. It now
8078 has either the following syntaxes
8080 ErrorDocument XXX /local/uri
8081 ErrorDocument XXX http://valid/url
8082 ErrorDocument XXX "Some Message"
8084 The recognition heuristic is: if it has a space it
8085 is a message. If it has no spaces and starts with a /
8086 or is a valid URL then treat it that way. Otherwise it
8087 is assumed to be a message.
8089 This breaks backward compatibility but makes live a hell
8090 of a lot easier for GUI's and config file parsers.
8091 [Dirk-Willem van Gulik]
8093 *) Changed 'CacheNegotiatedDocs' from its present/not-present
8094 syntax into a 'on' or 'off' syntax. As it currently is the
8095 only non nesting token which uses NO_ARGS and thus is an
8096 absolute pain for any config interface automation. This
8097 breaks backward compatibility. [Dirk-Willem van Gulik]
8099 *) Add ability to add external modules to the build process. This is
8100 done with --with-module=/path/to/module. Modules can only be added
8101 as static modules at this point.
8104 Changes with Apache 2.0a1
8106 *) Fix FreeBSD 3.3 core dump.
8107 Basically, ap_initialize() needs to get called before
8108 create_process(), since create_process() passes op_on structure
8109 to semop() to get a lock, but op_on isn't initialized until
8110 ap_initialize() calls setup_lock(). Here is a slight
8111 rearrangement to main() which calls ap_initialize() earlier...
8112 [Jeff Trawick <trawick us.ibm.com>]
8114 *) Enable Apache to use sendfile/TransmitFile API
8115 [Bill Stoddard, David Reid, Paul Reder]
8117 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
8121 *) Make file I/O and network I/O writev/sendv APIs consistent.
8122 Eliminate use of ap_iovec_t and use Posix struct iovec.
8123 Use seperate variable on ap_writev to set the number of iovecs
8124 passed in and number of bytes written.
8127 *) Adapt file iol to use APR functions. Replaced ap_open_file()
8128 with ap_create_file_iol(). ap_create_file_iol() requires that
8129 the file be opened prior to the call using ap_open().
8132 *) Port mod_include and mod_cgi to 2.0
8133 [Paul Reder, Bill Stoddard]
8135 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
8136 bytes_read/bytes_written is always valid (never -1). Plus
8137 some fixes to buff.c to correct problems introduced by the
8138 errno => ap_status_t changes a while back. Plus a fix to
8139 chunked encoding introduced right at the beginning of 2.0.
8142 *) Revamped UNIX build system to use autoconf and libtool.
8143 [Manoj Kasichainula, Sascha Schumann]
8145 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
8147 *) SECURITY: More rigorous checking of Host: headers to fix security
8148 problems with mass name-based virtual hosting (whether using mod_rewrite
8149 or mod_vhost_alias).
8150 [Ben Hyde, Tony Finch]
8152 *) Add back support for UseCanonicalName in <Directory> containers.
8153 [Manoj Kasichainula]
8155 *) Added APLOG_STARTUP log type. This allows us to write an error
8156 message without any of the date and time information. As a part
8157 of this change, I also removed all of the calls to fprintf(stderr
8158 and replaced them with calls to ap_log_error using APLOG_STARTUP
8159 writing to stderr is no longer portable, because we don't direct
8160 stderr to the error log on all platforms.
8163 *) Convert error logging functions to take errno as an argument.
8164 This makes our error logs more portable, because some Windows API's
8165 don't set errno. This change allows us to still output a valid
8166 message on all of our platforms.
8169 *) mod_mime_magic runs in 2.0-dev now.
8170 [Paul Reder <rederpj raleigh.ibm.com>]
8172 *) sendfile has been added to APR.
8173 [John Zedlewski <zedlwski Princeton.EDU>]
8175 *) buff.c has been converted to no longer use errno.
8176 [Manoj Kasichainula]
8178 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
8179 interface adaption to APR functions did it. [Martin Kraemer]
8181 *) Support DSOs properly on 32-bit HP-UX 11.0
8182 [Dilip Khandekar <dilip cup.hp.com>]
8184 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
8185 [Ralf S. Engelschall]
8187 *) Cleaned APR build environment integration and bootstrap APR
8188 automatically for developers from src/Configure.
8189 [Ralf S. Engelschall]
8191 *) Fixed building of src/support/htpasswd.c
8192 [Ralf S. Engelschall]
8194 *) When generating the Location: header, mod_speling forgot
8195 to escape the spelling-fixed uri. (Forw-Port from 1.3)
8198 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
8200 *) Change all pools to APR contexts. This is the first step to
8201 incorporating APR into Apache. [Ryan Bloom]
8203 *) Move "handler not found" warning message to below the check
8204 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
8205 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
8207 *) Support line-continuation feature in config.option file and
8208 allow the loading of multiple option sections at once via
8209 ``--with-option=<section1>,<section2>,...''
8210 [Ralf S. Engelschall]
8212 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
8214 Changes with Apache MPM
8216 *) Use asynchronous AcceptEx() and a completion port to accept and
8217 dispatch connections to threads in Windows NT/2000.
8220 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
8223 *) Implement the APACI --with-option facility
8224 (per default used the config.option file).
8225 [Ralf S. Engelschall]
8227 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
8229 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
8230 Replace pre_connection module call with a register_hook call and
8231 implement pre_connection as a hook. The intent is that these hooks will
8232 be extended to allow Apache to be multi-protocol, and also to allow the
8233 calling order to be specified on a per-hook/per-module basis.
8236 *) Implement mpm_* methods as "modules". Each method gets its own
8237 subdir in src/modules (eg: src/modules/prefork). Selection
8238 of method uses Rule MPM_METHOD. [Jim Jagielski]
8240 *) Port the hybrid server from the apache-apr repository as
8241 mpm_mpmt_pthread. [Manoj Kasichainula]
8243 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
8244 amongst the unix MPMs.
8246 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
8247 signal handling for the new world order. [Dean Gaudet]
8249 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
8250 of alloc.c for now. [Dean Gaudet]
8252 *) Handle partial large writes correctly. [Ben Laurie]
8254 *) Eliminate conn_rec's pointer to server. All it knows is the base server
8255 based on IP/port. [Ben Laurie]
8257 *) Port a bunch of modules to the new module structure.
8258 ["Michael H. Voase" <mvoase midcoast.com.au>]
8260 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
8262 *) Basic restructuring to introduce the MPM concept; includes various
8263 changes to the module API... better described by
8264 docs/initial_blurb.txt. [Dean Gaudet]
8266 Changes with Apache pthreads
8268 *) New buff option added: BO_TIMEOUT. It describes the timeout for
8269 buff operations (generally over a network).
8270 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
8272 *) Created http_accept abstraction. Added 4 new functions (not exported):
8273 init_accept(), begin_accepting_requests(), get_request(),
8274 stop_accepting_requests() [Bill Stoddard]
8276 *) Fix to ap_rprintf call that allows mod_info to work properly.
8277 [James Morris <jmorris intercode.com.au>]
8279 *) user and ap_auth_type fields were moved from connection_rec to
8280 request_rec. [Ryan Bloom]
8282 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
8283 needed in a threaded server.
8285 *) Initial pthread implementation from from Dean's apache-nspr code.
8286 [Bill Stoddard, Ryan Bloom]
8289 Changes with Apache 1.3.9
8291 *) Remove bogus error message when a redirect doesn't set Location.
8292 Instead, use an empty string to avoid coredump if the error message
8293 was supposed to include a location. [Roy Fielding]
8295 *) Don't allow configure to include mod_auth_digest unless it is
8296 explicitly requested, even if the user asked for all modules.
8299 *) Translate module names to dll names for OS/2 so that they are no more
8300 than 8 characters long and have an extension of "dll" instead of "so".
8303 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
8304 Fix test-compile check to check for randbyte instead of trand32.
8305 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
8306 and tweak to make Amaya happier. [Ronald Tschalär]
8308 *) Ensure that the installed expat include files are world readable,
8309 just like the other header files. [Martin Kraemer]
8311 *) Fixed generated AddModule adjustments in APACI's `configure' script
8312 in order to allow (new) modules like mod_vhost_alias to be handled
8313 correctly (which was touched by the adjustments for mod_alias).
8314 [Ralf S. Engelschall]
8316 *) For binary builds, add -R flag to apachectl to work around the lack of
8317 an absolute path to the ./libexec directory where the libhttp.ep file
8318 is needed for SHARED_CORE architectures. [Randy Terbush]
8320 *) WIN32: Create the CGI script process as DETACHED. This may solve the
8321 problem observed by some Win95/98 users where they get CGI script
8322 output sent to the console. [Bill Stoddard]
8324 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
8325 routines are now called ap_base64* and are 'plain' (i.e., no
8326 pool access or anything clever). Inside util.c the routines acting
8327 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
8328 The oddly named ap_uuencode(), ap_uudecode() are kept around for
8329 now but deprecated. [dirkx]
8331 *) Clean up the base64 and SHA1 additions and make sure they are
8332 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
8333 files. [Roy Fielding]
8335 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
8336 checking. Allow compiling on VS 6.0. [Randy Terbush]
8338 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
8340 *) Use TestCompile to search for the truerand library (rather than blindly
8341 assuming its existence). If it is not found, complain (but do not
8342 exit - yet). [Martin Kraemer]
8344 *) We forgot to add the new exported function names to
8345 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
8347 *) Add description of -T command-line option to usage().
8348 [Ralf S. Engelschall]
8350 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
8351 searched only AFTER libap has been searched, because libap needs
8352 some symbols from libos. [Martin Kraemer]
8354 *) Fix conflict with original mod_digest related to the symbol of the
8355 module dispatch list (which has to be unique for DSO and follow the
8356 usual conventions for the installation procedure).
8357 [Ralf S. Engelschall]
8359 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
8360 for other platforms as well. [Martin Kraemer]
8362 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
8363 types by AP_LONG and replace reference to renamed variable 'ubuf'
8364 by 'buffer'. [Martin Kraemer]
8366 Changes with Apache 1.3.8 [not released]
8368 *) Flush the output buffer immediately after sending an error or redirect
8369 response, since the result may be needed by the client to abort a
8370 long data transfer or restart a series of pipelined requests.
8371 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
8373 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
8374 [Ian Turner <iant sequent.com>] PR#4735
8376 *) Local struct mmap in http_core.c conflicted with system structure
8377 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
8379 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
8380 [Ronald Tschalär <ronald innovation.ch>]
8382 *) Fix a memory leak where the module counts were getting messed
8383 up across restarts. [David Harris <dharris drh.net>]
8385 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
8386 properly in mod_access.
8387 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
8389 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
8390 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
8392 *) PORT: Support for compaq/tandem/com.
8393 [Michael Ottati <michael.ottati compaq.com>, dirkx]
8395 *) Added SHA1 password encryption support to easy migration from
8396 Netscape servers. See support/SHA1 for more information.
8397 Caused the separation of ap_md5.c into md5, sha1 and a general
8398 ap_checkpass.c with just a validate_passwd routine. Added a
8399 couple of flags to support/htpasswd. Some reuse of the to64()
8400 function; hence renamed to ap_to64().
8401 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
8403 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
8404 with ASCII/EBCDIC conversions in "ident" query.
8405 [David McCreedy <McCreedy us.ibm.com>]
8407 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
8408 Change "Power Macintosh" to Power* so if uname prints "Power Book"
8409 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
8411 *) Fix SIGSEGV on some systems because the Vary fix below included
8412 a call to table_do with a variable argument list that was not
8413 NULL terminated. Replaced with better implementation. [Roy Fielding]
8415 Changes with Apache 1.3.7 [not released]
8417 *) The "Vary" response header field is now sanitised right before
8418 the header is sent back to the client. Multiple "Vary" fields
8419 are combined, and duplicate tokens (e.g., "Vary: host, host" or
8420 "Vary: host, negotiate, host, accept-language") are reduced to
8421 single instances. This is a better solution than the force-no-vary
8422 one (which is still valid for clients that can't cope with Vary
8423 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
8425 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
8427 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
8428 least on Linux and FreeBSD for now.
8431 *) Win32: More apache -k restart work. Restarts are now honored
8432 immediately and connections in the listen queue are -not- lost.
8433 This is made possible by the use of the WSADuplicateSocket()
8434 call. The listeners are opened in the parent, duplicated, then
8435 the duplicates are passed to the child. The original listen sockets
8436 are not closed by the parent across a restart, thus the listen queue
8438 [Bill Stoddard <stoddard raleigh.ibm.com>]
8440 *) Fix handling of case when a client has sent "Expect: 100-continue"
8441 and we are going to respond with an error, but get stuck waiting to
8442 discard the body in the pointless hope of preserving the connection.
8443 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
8445 *) Fix 'configure' to work correctly with SysV-based versions of
8446 'tr' (consistent with Configure's use as well). [Jim Jagielski]
8448 *) apxs: Add "-S var=val" option which allows for override of CFG_*
8449 built-in values. Add "-e" option which works like -i but doesn't
8450 install the DSO; useful for editing httpd.conf with apxs. Fix
8451 editing code so that multiple invocations of apxs -a will not
8452 create duplicate LoadModule/AddModule entries; apxs can now be
8453 used to re- enable/disable a module. [Wilfredo Sanchez]
8455 *) Win32: Update the server to use Winsock 2. Specifically, link with
8456 ws2_32.lib rather than wsock32.lib. This gives us access to
8457 WSADuplcateSocket() in addition to some other enhanced comm APIs.
8458 Win 95 users may need to update their TCP/IP stack to pick up
8459 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
8460 [Bill Stoddard <stoddard raleigh.ibm.com>]
8462 *) Win32: Redirect CGI script stderr (script debug info) into the
8463 error.log when CGI scripts fail. This makes Apache on Win32
8464 behave more like Unix.
8465 [Bill Stoddard <stoddard raleigh.ibm.com>]

8486 *) Fix apxs build issues on AIX
8487 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
8489 *) DocumentRoot Checking: Under previous versions, when Apache
8490 first started up, it used to do a stat of each DocumentRoot to
8491 see if it existed and was a directory. If not, then an error
8492 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
8493 does not exist, you will get error messages in error_log. If
8494 the '-t' command line option is used (to check the configuration)
8495 the check of DocumentRoot IS performed. An additional command
8496 line option, '-T', has been added if you want to avoid the
8497 DocumentRoot check even when checking the configuration.
8500 *) Win32: The query switch "apache -S" didn't exit after showing the
8501 vhost settings. That was inconsistent with the other query functions.
8502 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
8504 *) Win32: Changed behaviour of apache -k restart.
8505 Previously, the server would drain all connections in the stack's
8506 listen queue before honoring the restart. On a busy server, this
8507 could take hours. Now, a restart is honored almost immediately.
8508 All connections in Apache's queues are handled but connections in
8509 the stack's listen queue are discarded. Restart triggered by
8510 MaxRequestPerChild is unchanged.

8541 *) TestCompile updated. We can now run programs and output the
8542 results during the Configure process. [ Jim Jagielski]
8544 *) The source is now quad (long long) aware as needed. Specifically,
8545 the Configure process determines the correct size of off_t and
8546 *void. When the OS/platform/compiler supports quads, ap_snprintf()
8547 provides for the 'q' format qualifier (if quads are not available,
8548 'q' is silently "demoted" to long). [Jim Jagielski]
8550 *) When the username or password fed to htpasswd is too long, include the
8551 size limit in the error message. Also report illegal characters
8552 (currently only ':') in the username. Add the size restrictions
8553 to the man page. [Ken Coar]
8555 *) Fixed the configure --without-support option so it doesn't result in

8572 ap_regexec(). This solves problems with DSO modules which use the regex
8573 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]

8639 in unix/os.c, and don't install the dyld error handlers, which
8640 are no longer needed in Mac OS. [Wilfredo Sanchez]
8642 *) Rename Rhapsody layout to "Mac OS X Server". Change install
8643 locations to appropriate ones for user-built (as opposed to

8646 *) Modify mod_autoindex's handling of AddDescription so that the
8647 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
8649 *) Add functionality to the install-bindist.sh script created by
8650 binbuild.sh to use tar when copying distribution files to the
8651 serverroot. This allows upgrading an existing installation
8652 without nesting the new distribution in the old.
8654 install-bindist.sh now detects the local perl5 path to install
8655 apxs and dbmmanage with proper path to perl interpreter.
8657 Add an install-binsupport target which copies the source files
8658 for apxs and dbmmanage to bindist to allow these scripts to
8659 be properly installed relative to the destination serverroot.

8829 *) proxy ftp: instead of using the hardwired string "text/plain" as
8830 a fallback type for files served by the ftp proxy, use the

8832 This allows for special configurations like
8833 <Directory proxy:ftp://some.host>
8834 DefaultType gargle/blurb
8836 Additionally, add the Content-Encoding: header to FTP proxy replies
8837 when the encoding is defined (by the AddEncoding directive).
8838 Because it was missing, it was almost impossible to browse compressed
8839 files using the FTP proxy (works now perfectly in Communicator).
8840 The ftp proxy now also returns the Date: and Server: header lines (if not
8841 much else... This code is "somewhat" broken) like normal requests do.

8965 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
8966 correctly check for output errors and mark the connection as aborted.
8967 Replaced many direct (unchecked) calls to ap_b* routines with the

8972 Furthermore map lookups for non-existent keys are now cached as well.
8973 Additionally "txt" maps are now parsed with simple string functions
8974 instead of using ap_pregcomp(). As a side effect a bug that prevented

8991 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
8993 *) Add support for \n and \t to mod_log_config, can be used to produce
8994 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
8996 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
8998 *) Added informative error messages for failed munmap() and fseek() calls
8999 in http_core.c. [John Bley, Roy Fielding]
9001 *) Added some informative error messages for some failed malloc()
9002 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
9004 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
9005 is removed. This allows <Directory proxy:*> directives to work and
9006 prevents invalid requests from killing the process.
9007 [Brian Havard <brianh kheldar.apana.org.au>]
9009 *) Reorganised FAQ document.
9010 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497
9012 *) src/support/: The ApacheBench benchmark program was overhauled by
9013 David N. Welton: you can now have it generate an HTML TABLE, presumably
9014 for integration into other HTML sources. David updated the ab man page
9015 as well and added some missing descriptions. Thanks!
9016 [David N. Welton <davidw prosa.it>]
9018 *) Win32: The filename validity checker now allows filenames containing
9019 characters in the range 0x80 to 0xff (for example accented characters).
9020 [Paul Sutton] PR#3890
9022 *) Added conditional logging based upon environment variables to
9023 mod_log_config. mod_log_referer and mod_log_agent
9024 are now deprecated. [Ken Coar]
9026 *) Allow apache acting as a proxy server to relay the real
9027 reason of a failure to a client rather than the "internal
9028 server error" it does currently. The general exposure mechanism
9029 can be triggered by any module by setting the "verbose-error-to"
9030 note to "*"; this allows more than just proxy errors to be exposed.
9031 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
9033 *) Moved man pages for ab and apachectrl to section 8.
9034 [Wilfredo Sanchez, Roy Fielding]
9036 *) Added -S option to install.sh so that options can be passed to
9037 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
9039 *) Tweak modules Makefile generated by Configure so that it handles
9040 the test case of no modules being selected. [<chaz reliant.com>]
9042 *) Added a <LimitExcept method ...> sectioning directive that allows
9043 the user to assign authentication control to any HTTP method that
9044 is *not* given in the argument list; i.e., the logical negation
9045 of the <Limit> directive. This is particularly useful for controlling
9046 access on methods unknown to the Apache core, but perhaps known by
9047 some module or CGI script. [Roy Fielding, Tony Finch]
9049 *) Prevent apachectl from complaining if the PIDFILE exists but
9050 does not contain a process id, as might occur if the server is
9051 being rapidly restarted. [Wilfredo Sanchez]
9053 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
9055 *) Entity tag comparisons for If-Match and If-None-Match were not being
9056 performed correctly -- weak tags might cause false positives. Also,
9057 strong comparison wasn't properly enforced in all cases.
9058 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
9060 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
9063 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
9064 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
9066 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
9067 to util.c for parsing an HTTP header field value to extract the next
9068 list item, taking into account the possible presence of nested comments,
9069 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
9070 insignificant whitespace and lowercases non-quoted tokens.
9071 [Roy Fielding] PR#2065
9073 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
9074 code different from 500. This allows the proxy to, e.g., return
9075 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
9077 *) Fix ordering of language variants for the case where the traditional
9078 negotiation algorithm is being used with multiple language variants
9079 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
9081 *) Do not round the TCN quality calculation to 5 decimal places,
9082 unlike RFC 2296, because the calculation might need 12 decimal places
9083 to get the right result. [Roy Fielding]
9085 *) Remove unused code to disable transparent negotiation when
9086 negotiating on encoding only, as we now handle encoding too
9087 (though this is nonstandard for TCN), remove charset=ISO-8859-1
9088 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
9089 some debugging statements within mod_negotiation. [Koen Holtman]
9091 *) Fixed a rare memory corruption possibility in mod_dir if the index
9092 file is negotiable and no acceptable variant can be found.
9093 [Dean Gaudet, Roy Fielding, Martin Kraemer]
9095 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
9096 searching the Win32 registry for script interpreters.
9099 *) Win32: The compiled-in default filename for the error log is now
9100 error.log, which matches the default in the distributed httpd.conf.
9103 *) Win32: Any error messages from -i or -u command line options are now
9104 displayed on the console output rather than sent to the error log.
9105 Also the "Running Apache..." message is not output unless Apache is
9106 going to serve requests. [Paul Sutton]
9108 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
9109 and use a private significator ('$apr1$') to mark passwords as
9110 being smashed with our own algorithm. Also abstract the password
9111 checking into a new ap_validate_password() routine. [Ken Coar]
9113 *) Win32: The filename validity checker now allows "COM" but refuses
9114 access to "COM1" through "COM4". This allows filenames such
9115 as "com.name" to be served. [Paul Sutton] PR#3769.
9117 *) BS2000: Adapt to the new ufork() system call interface which will
9118 make subtasking easier on the OSD/POSIX mainframe environment.
9121 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
9122 ap_compat.h. [David White <david persimmon.com>] PR#3725
9124 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
9125 use `.db' instead of `.pag' not only for FreeBSD, but also when
9126 the NDBM library looks like Berkeley-DB based.
9127 [Ralf S. Engelschall] PR#3773
9129 *) Add ability to handle DES or MD5 authentication passwords.
9130 [Ryan Bloom <rbb Raleigh.IBM.Com>]
9132 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
9134 *) SECURITY: Avoid some buffer overflow problems when escaping
9135 quoted strings. (This overflow was on the heap and we believe
9136 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
9138 *) Let src/Configure be aware of CFLAGS options starting with plus
9139 signs as it's the case for the HP/UX compiler.
9140 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
9142 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
9143 and check to see if the tar we wind up with supports '-h'.
9144 [Jim Jagielski] PR#3671
9146 *) A consistent and conservative style for all shell scripts has been
9147 implemented. Basically, all shell string tests use the traditional
9148 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
9149 to protect against bare null variable strings (ie: wrapping both
9150 sides with double quotes and prepending 'x'). 'x' was chosen
9151 because it's more universal and hopefully easier for old shell
9152 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
9155 *) The status module now prints out both the main server generation as
9156 well as the generation of each process. Also, the vhost info is
9157 printed with '?notable'. [Jim Jagielski]
9159 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
9160 and this makes its functions available to things in src/support.
9163 Changes with Apache 1.3.4
9165 *) Renamed macros status_drops_connection to ap_status_drops_connection
9166 and vestigial scan_script_header to ap_scan_script_header_err,
9167 mostly for aesthetic reasons. [Roy Fielding]
9169 *) The query switch "httpd -S" didn't exit after showing the
9170 vhost settings. That was inconsistent with the other query functions.
9173 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
9174 filename to the end of the STANDARD_MODULE_STUFF. Its
9175 presence at the beginning prevented reporting of the filename
9176 for modules compiled before 1 January 1999. [Ken Coar]
9178 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
9179 to detect and prevent access to special DOS device file names.
9180 [Paul Sutton, Ken Parzygnat]
9182 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
9183 and Makefile_win32_debug.txt (debug build) that work on Win95.
9184 Run each of the following from the src directory:
9185 nmake /f Makefile_win32.txt # compiles normal build
9186 nmake /f Makefile_win32.txt install # compiles and installs
9187 nmake /f Makefile_win32.txt clean # removes compiled junk
9188 nmake /f Makefile_win32_debug.txt # compiles debug build
9189 nmake /f Makefile_win32_debug.txt install
9190 nmake /f Makefile_win32_debug.txt clean
9193 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
9194 to build binary distributions. [Lars Eilebrecht]
9196 *) IndexOptions SuppressColumnSorting only turned off making
9197 the column headers anchors; you could still change the display
9198 order by manually adding a '?N=A' or similar query string to the
9199 URL. Now SuppressColumnSorting locks in the sort order so
9200 it can't be overridden this way. [Ken Coar]
9202 *) Added IndexOrderDefault directive to supply a default sort order
9203 for FancyIndexed directory listings. [Ken Coar] PR#1699
9205 *) Change the ap_assert macro to a variant that works on all platforms.
9206 [Richard Prinz <richard.prinz cso.net>] PR#2575
9208 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
9209 search for an underscore on dlsym() (as it's already the case
9210 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
9212 *) Small fix for mod_env.html: The module was documented as to be _not_
9213 compiled into Apache per default, although it _IS_ compiled into
9214 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
9216 *) Instead of fixing a bug in the generation procedure for config.status (a
9217 backslash was missing) we remove the bug together with it's complete
9218 context because the special cases of the past can now no longer occur
9219 because of the recent magic for the --with-layout default.
9220 [Ralf S. Engelschall] PR#3590
9222 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
9223 making sure the src/support/ tools are _forced_ to be build last (they
9224 depend on other libraries).
9225 [Markus Theissinger <markus.theissinger gmx.de>]
9227 *) Fix installation procedure: Now that os-inline.c is actually used (a
9228 recently fixed bug prevented this) we need to also install os-include.c
9229 in addition to os.h into the PREFIX/include/ location or building of
9230 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
9232 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
9233 allow us to distinguish between a garbled DSO (or even a file which isn't
9234 an Apache module DSO at all) and a DSO which doesn't match the current
9235 Apache API. [Ralf S. Engelschall] PR#3152
9237 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
9238 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
9239 match case insensitive (this especially avoids nasty patterns like
9240 `[tT][eE][sS][tT]'). Second two additional internal map functions
9241 `escape' and `unescape' were added which can be used to escape/unescape
9242 to/from hex-encodings in URLs parts (this is especially useful in
9243 combination with map lookups).
9244 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
9246 *) Renamed the macro escape_uri() to ap_escape_uri() which was
9247 forgotten (because it was a macro) in the symbol renaming process.
9248 [Ralf S. Engelschall]
9250 *) Fix some inconsistencies related to the scopes of directives. The only
9251 user visible change is that the directives `UseCanonicalName' and
9252 `ContentDigest' now use the (more correct) `Options' scope instead of
9253 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
9255 *) Using DSO, the Server token was being mangled. Specifically, the
9256 module's token was being added first before the Apache token. This
9257 has been fixed. [Jim Jagielski]
9259 *) Major overhaul of mod_negotiation.c, part 2.
9260 - properly handle "identity" within Accept-Encoding.
9261 - allow encoded variants in RVSA negotiation and let them appear in
9262 the Alternates field using the non-standard "encoding" tag-list.
9263 - fixed both negotiation algorithms so that an explicitly accepted
9264 encoding is preferred over no encoding if "identity" is not
9265 included within Accept-Encoding.
9266 - added ap_array_pstrcat() to alloc.c for efficient concatenation
9267 of large substring sequences.
9268 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
9271 *) Major overhaul of mod_negotiation.c, part 1.
9272 - cleanups to mod_negotiation comments and code structure
9273 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
9274 support for everything in the upcoming HTTP/1.1
9275 revision (draft-ietf-http-v11-spec-rev-06.txt).
9276 - language tag matching also handles tags with more than 2
9278 - empty Accept, Accept-Language, Accept-Charset headers are
9279 processed correctly; previously an empty header would make all
9280 values acceptable instead of unacceptable.
9281 - allowed for q values in Accept-Encoding
9282 - added support for transparent content negotiation (rfc2295 and
9283 rfc2296) (though we do not implement all features in these drafts,
9284 e.g. no feature negotiation). Removed old experimental version.
9285 - implemented 'structured entity tags' for better cache correctness
9286 (structured entity tags ensure that caches which can deal with Vary
9287 will (eventually) be updated if the set of variants on the server
9289 - this involved adding a vlist_validator element to request_rec
9290 - this involved adding the ap_make_etag() function to the global API
9291 - modified guessing of charsets used by Apache negotiation algorithm
9292 to guess 'no charset' if the variant is not a text/* type
9293 - added code to sort multiviews variants into a canonical order so that
9294 negotiation results are consistent across backup/restores and mirrors
9295 - removed possibility of a type map file resolving to another type map
9296 file as its best variant
9297 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
9299 *) RFC2396 allows the syntax http://host:/path (with no port number)
9300 but the proxy disallowed it (ap_proxy_canon_netloc()).
9301 [David Kristol <dmk bell-labs.com>] PR#3530
9303 *) When modules update/modify the file name in the configfile_t structure,
9304 syntax errors will report the updated name, not the original one.
9305 [Fabien Coelho <coelho cri.ensmp.fr>] PR#3573
9307 *) Correct some filename case assumptions from WIN32 to
9308 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
9310 *) For %v log ServerName regardless of the UseCanonicalName
9311 setting (similarly for %p). [Dean Gaudet]
9313 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
9314 rather late (too late for some invocations of TestCompile).
9315 This improves the make environment available to TestCompile and
9316 the *.module scripts. [Martin Kraemer]
9318 *) The hashbang emulation code in ap_execve.c would interpret
9319 #!/hashbang/scripts correctly, but failed to fall back to a
9320 standard shell for scripts which did NOT start with #!
9321 Now SHELL_PATH is started in these cases. [Martin Kraemer]
9323 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
9326 *) Update APXS manual page: some -q option arguments were missing
9327 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
9329 *) Cleanup the command line options: `-?' was documented to show
9330 the usage list but does it with an error because `?' is not a valid
9331 command. OTOH a lot of users expect `-h' to print such a usage list and
9332 instead are annoyed for ages by our huge unreadable list of directives.
9333 So we now changed the command line options this way:
9335 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
9336 very similar to the popular linker option.
9338 Intent: while -l gives the small list of modules, -L now gives the
9339 large list of directives implemented by these modules. This is also
9340 consistent with -v (short version info) and -V (large version info).
9342 Intent: it's now the expected option ;-)
9343 The manual page was adjusted accordingly.
9344 [Ralf S. Engelschall] PR#2714
9346 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
9347 wasn't defined. [Rick Franchuk <rickf transpect.net>]
9349 *) Removed recently introduced bugs and disfigurements in APACI:
9350 o fixed argument line processing: using $args was broken: It was not
9351 initialized and using args="$args $apc_option" and even args="$args
9352 \"$apc_option\"" fails in the second processing round for any arguments
9353 containing whitespaces. The only correct way is to use the construct
9354 "$@" (but not possible here) or iterate _both_ times over the implicit
9355 argument line (no argument to for-loop) which is what we now use.
9356 o make --with-layout=Apache the default without creating
9357 redundancy (copying the --with-layout block in the argument parsing
9358 loop). We achieve this by using the "$@" construct together with the
9359 `set' command to prepend --with-layout=Apache to the command line in
9360 case --with-layout is not used.
9361 o fixed auto-suffix handling now that config.layout exists.
9362 Paths which are auto-suffixed are marked with a trailing plus sign in
9363 config.layout and every path now can be marked this way (not only the
9364 four paths for which we do it currently). Additionally the suffix is
9365 no longer a static one. Instead it's now `/<target>' where <target> is
9366 the argument of the --target option or per default `httpd'.
9367 o allow also tabs (and only spaces) where we match whitespaces
9368 o various fixes and cleanups related to used shell coding style
9369 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
9370 o trimmed output of --help to fit into 80 columns
9371 [Ralf S. Engelschall]
9373 *) Added two new core API functions, ap_single_module_configure() and
9374 ap_single_module_init(), which are now used by mod_so to configure a module
9375 after loading. [Ralf S. Engelschall]
9377 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
9378 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
9379 of ap_config.h to allow serialized accept for multiport listens.
9380 [Roy Fielding, Curt Sampson] PR#3120
9382 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
9383 of ap_config.h that would skip several defines if DEFAULT_GROUP
9384 was overridden. [Roy Fielding]
9386 *) PORT: The I86 version of DGUX has support for strncasecmp and
9387 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
9389 *) Fix ordering of definitions in ap_config.h so that ap_inline is
9390 defined before it might be used. [Victor Khimenko]
9392 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
9393 [Tom Serkowski <tks bsdi.com>] PR#3453
9395 *) Make generation of src/Configuration.apaci more robust: It failed to
9396 differenciate between modules when one module name was a postfix of
9397 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
9398 just XXX (think about totally non-standard names like "apache_ssl", too).
9399 [Ralf S. Engelschall] PR#3380
9401 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
9402 since 1.3b7) and make whitespace handling more robust (it failed horrible
9403 when whitespaces were present in the arguments of -D options).
9404 [Ralf S. Engelschall] PR#3240
9406 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
9407 creates an external package shadow tree in DIR before the local build
9408 shadow tree is generated under DIR. This way one can have the extracted
9409 Apache distribution tree read-only on NFS or CDROM and still build Apache
9410 from these sources. An automatically triggered VPATH-like mechanism is
9411 provided through the TOP variable, too.
9412 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez apple.com>]
9414 *) Fix negotiation so that a Vary response header is correctly
9415 generated when, for a particular dimension, variants only vary
9416 in having or not having a value for that dimension. [Paul Sutton]
9418 *) Fix negotiation so that we prefer an encoded variant over an
9419 unencoded variant if the user-agent explicitly says it can
9420 accept that encoding. Previously we always preferred the unencoded
9422 [Paul Ausbeck <paula alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
9424 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
9425 and the usage page was inconsistent with the functionality and manpage.
9426 [Ralf S. Engelschall]
9428 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
9429 They can occur multiple times and their arguments (`xxx') are passed AS
9430 IS to the compiler/linker command. [Ralf S. Engelschall]
9432 *) Fixed possible (but harmless in practice) bug in the DBM lookup
9433 procedure of mod_rewrite: very long keys were truncated.
9434 [Ralf S. Engelschall]
9436 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
9437 identifier, currently "Apache" and "GNU" are pre-defined in the file
9438 config.layout. Custom layouts are possible by using FILE:ID as the
9439 argument where the layout ID is taken from FILE.
9441 The config.layout file consists of <Layout ID>..</Layout> sections
9442 where inside those sections "path_variable: path_value" pairs can be
9443 specified. These lines are converted to path_variable='path_value'.
9445 *) Add a DefaultLanguage directive so that files missing a language
9446 extension (e.g., .fr, .de) can be labelled as being some other
9447 default language. DefaultLanguage can appear in <Directory> and
9448 <Files> containers as well as .htaccess files. [Paul Sutton]
9451 *) Fix TARGET configuration when configuring and installing using
9452 APACI configure. TARGET now defines the basename of the configuration
9453 file, startup script, manual page, etc. log_error_core() now reports
9454 the server binary name given by argv[0]. TARGET can now also be defined
9455 with --target=TARGET parameter passed to APACI configure.
9456 [Ralf Engelschall, Randy Terbush]
9458 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
9459 rather than OPT_INCLUDES [Rainer Schoepf <schoepf uni-mainz.de>]
9461 *) ap_md5_binary() was using sprintf() rather than a table lookup
9462 to convert binary bytes to hex digits.
9463 [Ronald Tschalär <ronald innovation.ch>] PR#3409
9465 *) Fix SEGV in TCN negotiation if no variants are acceptable.
9466 [Martin Plechsmid <plechsmi karlin.mff.cuni.cz>] PR#1987
9468 *) API: ap_exists_config_define() function is now "public" [Doug MacEachern]
9470 *) Fix documentation of `Action' directive: It can activate a CGI script
9471 when either a handler or a MIME content type is triggered by the request.

9478 notice to the error log. It is not possible to send a 401 response
9479 and a redirect at the same time. [Lars Eilebrecht]
9481 *) Fallback to native compilers for IRIX-32 platform. It seems that
9482 a gcc 2.8.1 compiled apache is logging client addresses with all
9483 bits set (255.255.255.255). This is the second such problem caused
9484 by gcc 2.8.1 compiler. The first being broken semaphore locking.

9564 supported for the option argument: first BEGIN:foo which permutes module
9565 mod_foo with the begin of the module list, i.e. it `moves' the module to
9566 the begin of the list (gives it lowest priority). And second foo:END
9567 which permutes mod_foo with the end of the module list, i.e. it `moves'
9568 the module to the end of the list (gives it highest priority).

9647 of the protocol processing, which is extra nice because it works
9648 between continuation lines, is almost no cost in the normal case
9649 of no extra whitespace, and saves memory. [Roy Fielding]

9771 You now must define a BS2000Account name for the server User.
9772 This has fewer security implications than the old approach.
9775 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
9776 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
9777 platform to make the braindead HPUX linker happy. Notice, for the module
9778 DSOs we don't have to use this, because these are loaded manually (and

9790 *) Make PrintPath work generically instead of having one version
9791 strictly for OS/2. [Jim Jagielski, Brian Havard]
9793 *) Fix the recently introduced C header file checking: We now use the C
9794 pre-processor pass only (and no longer the complete compiler pass) to
9795 determine whether a C header file exists or not. Because only this way
9796 we're safe against inter-header dependencies (which caused horrible
9797 portability problems). The only drawback is that we now have a CPP
9798 configuration variable which has to be determined first (we do a similar
9799 approach as GNU Autoconf does here). When all fails the user still has
9800 the possibility to override it manually via APACI or src/Configuration.
9801 As a fallback for the header check itself we can directly check the
9802 existance of the file under /usr/include, too.

9836 -msym is just to optimize the DSO statup time a little bit it's safe and
9837 best when we leave it out now. [Ralf S. Engelschall] PR#2969

9845 *) Allow "Include" directives anywhere in the server config
9846 files (but not .htaccess files). [Ken Coar] PR#2727

9849 port 443 (https://) and 563 (snews://). The new AllowCONNECT
9850 directive allows the configuration of the ports to which a
9851 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
9853 *) mod_expires will now act on content that is not sent from a file
9854 on disk. Previously it would never add an Expires: header to
9855 any response that did not come from a file on disk; the only
9856 case where it still doesn't (and can't) add one for that type of
9857 content is if you are using a modification date based setting.
9858 [Marc Slemko, Paul Phillips <paulp go2net.com>]
9860 *) Problems encountered during .htaccess parsing or CGI execution
9861 that lead to a "500 Server Error" condition now provide explanatory
9862 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
9865 *) Add NameWidth keyword to IndexOptions directive so that the

9869 *) Recognize lowercase _and_ uppercase `uname' results under

9872 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
9873 a common problem of (mis-administrated?) IIS servers, make the apache
9874 proxy immune to these errors (and ignore the duplicates, but log
9875 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
9877 *) The <IfModule and <IfDefine block starting directives now only
9878 allow exactly one argument. Previously, the optional negation
9879 character '!' could be separated by whitespace without a syntax
9880 error being reported, albeit defeating the IfModule functionality
9881 (enclosed directives would ALWAYS be executed). By using the
9882 stricter syntax, these hard-to-track errors can be avoided.
9885 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
9886 cause the standalone FancyIndexing directive to logically OR
9887 into any existing IndexOptions settings rather than wiping
9888 them out. [Ken Coar]
9890 *) Changes in ftp proxy: make URL parsing simpler by using the
9892 + Add display of the "current directory" in cases where it's
9893 different from the supplied path (e.g., ftp://user@host/ lives
9894 in /home/user, not in /, therefore clicking on "../" in the
9895 starting directory might send us to /home/).
9896 + When ftp login fails, (esp. when a user name was part of the
9897 URL already), we now return [401 Unauthorized ] to allow the
9898 browser to pop up an authorization dialog. This makes passwords
9899 slightly less visible (they don't appear in the regular log files)
9900 and implements a functionality that other www proxy servers
9904 *) Triggered by the recent "Via:" header changes, the proxy module would
9905 dump core for replies with invalid headers (e.g., duplicate
9906 "HTTP/1.0 200 OK" lines). These errors are now logged and the
9907 core dump is avoided. Also, broken replies are not cached.

9968 compile time, for least astonishment of the user.
9971 *) When READing a request in ExtendedStatus mode, the "old"
9972 vhost, request and client information is not displayed.
9975 *) STATUS is no longer available. Full status information now
9976 run-time configurable using the ExtendedStatus directive.
9979 *) SECURITY: CVE-1999-1199 (cve.mitre.org)
9980 Eliminate O(n^2) space DoS attacks (and other O(n^2)
9981 cpu time attacks) in header parsing. Add ap_overlap_tables(),
9982 a function which can be used to perform bulk update operations
9983 on tables in a more efficient manner. [Dean Gaudet]
9985 *) SECURITY: Added compile-time and configurable limits for
9986 various aspects of reading a client request to avoid some simple
9987 denial of service attacks, including limits on maximum request-line
9988 size (LimitRequestLine), number of header fields (LimitRequestFields),
9989 and size of any one header field (LimitRequestFieldsize). Also added
9990 a configurable directive LimitRequestBody for limiting the size of the

10009 *) The 'status' module will now show the process pid's and their
10010 state even without full STATUS accounting. [Jim Jagielski]

10036 directory was renamed to src/os/os2/ for consistency.

10039 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO

10041 This is done by determining a subset of LIBS which can be safely used for
10042 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
10043 disabled for all platforms to avoid problems with this (experimental)
10044 rule. But we provide it now for those people how ran into problems and
10045 want to came out by forcing linking against DSOs.

10370 *) Add httpd -t (test) option for running configuration syntax tests only.
10371 If something is broken it complains and exits with a return code

10373 configuration after editing and is also automatically used by apachectl
10374 on (graceful) restart command to make sure Apache doesn't die on restarts
10375 because of a configuration which is now broken since the last (re)start.
10376 This way `apachectl restart' can be used inside cronjobs without having

10447 [Jens-Uwe Mager <jum helios.de>]
10449 *) Workaround for configure script and old `test' commands which do not
10450 support the -x flag (for instance under platforms like Ultrix). This is
10451 solved by another helper script findprg.sh which searches for Perl and
10452 Awk like PrintPath but _via different names_.
10453 [Ralf S. Engelschall]
10455 *) Remove the system() call from htpasswd.c, which eliminates a system
10456 dependancy. ["M.D.Parker" <mdpc netcom.com>] PR#2332
10458 *) PORT: Fix compilation failures on NEXTSTEP.
10459 [Rex Dieter <rdieter math.unl.edu>] PR#2293, 2316
10461 *) PORT: F_NDELAY is a typo, should have been FNDELAY. There's also
10462 O_NDELAY on various systems. [Dave Dykstra <dwd bell-labs.com>] PR#2313
10464 *) PORT: helpers/GuessOS updates for various versions for NCR SVR4.

10468 *) Fix recently introduced Win32 child spawning code in mod_rewrite.c which
10469 was broken because of invalid ap_pstrcat() -> strcat() transformation.
10470 [Ralf S. Engelschall]
10472 *) Proxy Cache Fixes: account for directory sizes, fork off garbage collection
10473 to continue in background, use predefined types (off_t, size_t, time_t),
10474 log the current cache usage percentage at LogLevel debug
10475 [Martin Kraemer, based on discussion between Dean Gaudet & Dirk vanGulik]
10477 Changes with Apache 1.3.0
10479 *) Using a type map file as a custom error document was not possible.
10480 [Lars Eilebrecht] PR#1031
10482 *) Avoid problems with braindead Awks by additionally searching for gawk
10483 and nawk in APACI's configure script.
10484 [Dave Dykstra <dwd bell-labs.com>, Ralf S. Engelschall] PR#2319
10486 *) Rename md5.h to ap_md5.h to avoid conflicts with native MD5 on
10487 some systems. [Randy Terbush]
10489 *) Change usage of perror()+fprintf(stderr,...) in mod_rewrite to
10490 more proper ap_log_error() variants.
10491 [Ralf S. Engelschall]
10493 *) Make sure the argument for the --add-module option to APACI's configure
10494 script is of type [path/to/]mod_xxx.c because all calculations inside
10495 configure and src/Configure depend on this.
10496 [Ralf S. Engelschall] PR#2307
10498 *) Changes usage of perror/fprintf to stderr to more proper ap_log_error
10499 in mod_mime, mod_log_referer, mod_log_agent, and mod_log_config.
10502 *) Various OS/2 cleanups ["Brian Havard" <brianh kheldar.apana.org.au>]
10504 *) PORT: QNX needed a #include <sys/mman.h>; and now it uses flock
10505 serialized accept to handle multiple sockets.
10506 [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2295, 2296
10508 *) Have NT properly set the directory for CGI scripts
10509 (& other spawned children)
10510 [W G Stoddard <wgstodda us.ibm.com>]
10512 *) Propagate environment to CGI scripts correctly in Win32.
10513 [W G Stoddard <wgstodda us.ibm.com>] PR#2294
10515 *) Some symbol renaming:
10516 ap_spawn_child_err became ap_spawn_child
10517 ap_spawn_child_err_buff became ap_bspawn_child
10518 spawn_child was obsoleted and moved to compat.h
10521 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
10522 programs: ap_spawn_child_err() is used and the Win32 case now uses
10523 CreateProcess() instead of a low-level execl() (which caused problems in
10524 the past under Win32).
10525 [Ralf S. Engelschall]
10527 *) A few cosmetics and trivial enhancements to APXS to make the
10528 generated Makefile more user friendly. [Ralf S. Engelschall]
10530 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
10531 was updated to use the normal apache error processing, thereby allowing
10532 proxy errors to be treated by ErrorDocument's as well. For this
10533 purpose, a new module-to-core communication variable "error-notes"
10534 was introduced; the proxy (and possibly other modules) communicates
10535 its error text using this variable. Its content is copied to a new
10536 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
10537 The old proxy special error routine ap_proxy_log_uerror()
10538 was replaced by regular ap_log_error() calls, many messages were made
10540 [Martin Kraemer] PR#494, 1259
10542 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
10545 *) Transform the configure message "You need root privileges for suEXEC"
10546 from a fatal error into a (more friendly) warning because the building
10547 ("make") of Apache we can allow, of course. Root privileges are needed
10548 only for the installation step ("make install"). So make sure the
10549 user is aware of this fact but let him proceed as long as he can.
10550 [Ralf S. Engelschall] PR#2288
10552 *) Renamed three more functions to common ap_ prefix which we missed at the
10553 Big Symbol Renaming because they're #defines and not real C functions:
10554 is_default_port(), default_port(), http_method().
10555 [Ralf S. Engelschall]
10557 *) A zero-length name after a $ in an SSI document should cause
10558 just the $ to be in the expansion. This was broken during the
10559 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
10561 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
10562 memory. [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2252
10564 *) Fix src/support/httpd.exp (DSO export file which is currently only
10565 used under AIX) because of recent changes to function names.
10566 [Ralf S. Engelschall]
10568 Changes with Apache 1.3b7
10570 *) Make sure a MIME-type can be forced via a RewriteRule even when no
10571 substitution takes place, for instance via the following rule:
10572 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
10573 requested by users in the past to force a single script without a .cgi
10574 extension and outside any cgi-bin dirs to be executed as a CGI program.
10575 [Ralf S. Engelschall] PR#2254
10577 *) A fix for protocol issues surrounding 400, 408, and
10578 414 responses. [Ed Korthof]
10580 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
10582 *) Fix discrepancy in proxy_ftp.c which was causing failures when
10583 trying to connect to certain ftpd's, such as anonftpd.
10584 [Rick Ohnemus <rick ecompcon.com>]
10586 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
10587 logfile instead of fiddling around itself with child spawning stuff.
10588 [Ralf S. Engelschall]
10590 *) Made RefererIgnore case-insensitive.
10592 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
10595 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
10596 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
10599 *) Improve RFC1413 support. [Bob Beck <beck bofh.ucs.ualberta.ca>]
10601 *) Fix support script `dbmmanage': It was unable to handle some sort
10602 of passwords, especially passwords with "0" chars.
10603 [Ralf S. Engelschall] PR#2242
10605 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
10606 [Ben Laurie] PR#2238
10608 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
10609 library), so CGI handling has been changed to use Win32 native handles
10610 instead of C file descriptors.
10611 [Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
10613 *) The proxy cache would store an incorrect content-length in the cached
10614 file copy after a cache update. That resulted in repeated fetching
10615 of the original copy instead of using the cached copy.
10616 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
10618 *) The Makefiles assumed that DSO files are build via $(LD). This
10619 is broken for two reasons: First we never defined at least LD=ld
10620 somewhere to make sure this works (it was silently assumed that most Make
10621 provide a built-in LD definition - ARGL!) and second using the generic LD
10622 variable is not the truth. Instead a special variable named LD_SHLIB is
10623 reasonable because although "ld" is usually the default, the command for
10624 building DSO files can be "libtool" or even "cc" on some systems.
10625 [Ralf S. Engelschall]
10627 *) Replace the AddVersionPlatform directive with ServerTokens which
10628 provides for more control over the format of the Server:
10629 header line. SERVER_SUBVERSION is no longer supported;
10630 all module should use the ap_add_version_component()
10631 API function instead. [Jim Jagielski]
10633 *) Support for the NCR MP/RAS 3.0
10634 [John Withers <withers semi.kcsc.mwr.irs.gov>]
10636 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
10637 not retrieved in src/Configure and thus was not useable.
10638 [Ralf S. Engelschall]
10640 *) Various Makefile consistency cleanups:
10641 - make OSDIR also automatically be relative to src/ like INCDIR
10642 - SUBDIRS is now generated in src/Makefile only and not in
10643 Makefile.config because it is a local define for this location.
10644 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
10645 any Makefile but make sure that at least the "-K inline" is kept in
10647 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
10648 - updated the dependencies theirself
10649 - removed not existing SHLIB variable from "clean" targets
10650 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
10651 already exists and OBJS_PIC are also just plain objects and have not
10652 directly to do with "shared" things. The only difference is that they
10653 contain PIC. So OBJS_PIC is the more canonical name.
10654 - Updated the Makefile-dependency lines for OBJS_PIC
10655 - Removed the Makefile-dependency line in Configure to avoid double
10657 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
10658 of xxx.lo as GNU libtool does with its PIC objects
10659 - reduce local complexity in modules Makefile.tmpl by moving the last
10660 existing target "depend" to the generation section in Configure, too.
10661 - removed the historical $(SPACER) which was used in the past together
10662 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
10663 is no longer needed.
10664 - force the build and run of the gen_xxx programs under main/ as the
10665 first step before building the objects because it looks cleaner
10666 [Ralf S. Engelschall]
10668 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
10671 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
10674 *) WIN32: Don't force ISAPI headers to finish with \n.
10675 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
10677 *) When opening "configuration" files (like httpd.conf, htaccess
10678 and htpasswd), Apache will not allow them to be non-/dev/null
10679 device files. This closes a DoS hole. At the same time,
10680 we use ap_pfopen to open these files to handle timeouts.
10681 [Jim Jagielski, Martin Kraemer]
10683 *) Apache will now log the reason its httpd children exit if they exit
10684 due to an unexpected signal. (It requires a new porting define,
10685 SYS_SIGLIST, which if defined should point to a list of text
10686 descriptions of the signals available. See PORTING.) [Dean Gaudet]
10688 *) WIN32: chdir() doesn't make sense in a multithreaded environment
10689 like WIN32. Before, Win32 CGI's could have had sporadic failures
10690 if a chdir call from one thread was made between another chdir call
10691 and a spawn in another thread. So, for now don't chdir for CGI scripts
10692 in WIN32. The current CGI "spec" is unclear as to whether it's
10693 necessary. Long-term fix is to either serialize the chdir/spawn combo
10694 or use WIN32 native calls to spawn a process. This temp fix was
10695 necessary to remove this as a showstopper for 1.3's release.
10698 *) Cleanup the suEXEC support in APACI and make it more safe:
10699 1. Add big fat hint in INSTALL about risks and to read the
10700 htdocs/manual/suexec.html document before using the suexec-related
10702 2. Make sure the user has at least provided one --suexec-xxxx option
10703 (specifies suEXEC parameters) in addition to --enable-suexec option.
10704 If only --enable-suexec is given APACI stops with a hint to INSTALL
10705 and htdocs/manual/suexec.html documents.
10706 3. Provide two additional --suexec-xxxx options to make the suEXEC
10707 configuration complete (especially for package maintainers who else
10708 had to patch the source tree) by providing ways to configure minimal
10709 UID/GID and safe PATH, too.
10710 [Ralf S. Engelschall]
10712 *) Cleanup of the `configure --shadow' process:
10713 - make sure the configure script creates its temporary files in the
10714 shadow tree to avoid conflicts with parallel configure runs
10715 - removed unnecessary option "-r" from "rm" call for Makefiles
10716 - make sure the configure scripts creates the shadow-wrapper Makefile
10717 only when no shadow trees already exists
10718 - make sure "make distclean" removes the shadow-wrapper Makefile but only
10719 when no more shadow trees exists
10720 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
10721 as fast (in the past it needed 70sec, now it runs just 38sec)
10722 - make sure CVS does not complain about the created files
10723 Makefille.<gnutriple> and directories src.<gnutriple>
10724 [Ralf S. Engelschall]
10726 *) Added the ap_add_version_component() API routine and the
10727 AddVersionPlatform core directive. The first allows modules to
10728 declare themselves in the Server response header field value,
10729 augmenting the SERVER_SUBVERSION define in the Configuration file
10730 with run-time settings (more useful in a loadable-module environment).
10731 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
10732 into the server version string. [Ken Coar] PR#2056
10734 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
10737 *) Emit the "Accept-Range" header for the default handler.
10738 [Brian Behlendorf] PR#1464
10740 *) Add a note to httpd.conf-dist that apache will on some systems fail
10741 to start when the Group # is set to a negative or large positive value.
10744 *) Make sure the module execution order is correct even when some modules
10745 are loaded under runtime (`LoadModule') via the DSO mechanism:
10746 1. The list of loaded modules is now a dynamically allocated one
10747 and not the original statically list from modules.c
10748 2. The loaded modules are now correctly setup by LoadModule for
10749 later use by the AddModule command.
10750 3. When the DSO mechanism for modules is used APACI's `install'
10751 target now enables all created `LoadModule' lines per default because
10752 this is both already expected by the user _and_ needed to avoid
10753 confusion with the next point and reduces the Makefile.tmpl complexity
10754 4. When the DSO mechanism for modules is used, APACI's `install'
10755 target now additionally makes sure the module list is reconstructed
10756 via a complete `ClearModuleList+AddModule...' entry.
10757 5. The support tool `apxs' now also makes sure an AddModule command
10758 is added in addition to the LoadModule command.
10759 6. The modules.c generation was extended to now contain two
10760 comments to make sure no one is confused by the confusing terminology
10761 of loading/linking (we use load=link+load & link=activate instead of
10762 the obvious load=activate & link=link :-( )
10763 This way now there is no longer a difference under execution time between
10764 statically and dynamically linked modules.
10765 [Ralf S. Engelschall]
10767 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
10768 Big Symbol Renaming. [Ralf S. Engelschall]
10770 *) Add a comment to mod_example.c showing the format of a FLAG command
10771 handler. [Ken Coar]
10773 *) Standardized the time format in mod_status to match that of other
10774 places in the code (e.g. DATE_GMT). PR#1551
10776 *) Fix handling of %Z in timefmt strings for those platforms with no time
10777 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
10780 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
10781 feature compatible with 'UseCanonicalName off' by changing
10782 r->server->server_hostname to ap_get_server_name(). And I changed some
10783 functions which use r->server->port to use ap_get_server_port() instead,
10784 because if there's no Port directive in the config r->server->port is 0.
10787 *) get/set_module_config are trivial enough to be better off inline. Worth
10788 1.5% performance boost. [Dean Gaudet]
10790 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
10791 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
10794 *) [BS2000 security] BS2000 needs an extra authentication to initialize
10795 the task environment to the unprivileged User id. Otherwise CGI scripts
10796 would have a way to gain super user access. [Martin Kraemer]
10798 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
10799 absolute path, only log base name of logging source as is done
10800 in unix. [Martin Kraemer]
10802 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
10803 the encoding type from the Accept-Encoding header (if it's there)
10804 and use it in the response, as that's probably what it'll be expecting.
10805 [<Ronald.Tschalaer psi.ch>]
10807 *) Fix to mod_alias: translate_alias_redir is dealing with
10808 a URI, not a filename, so the check for drive letters for win32
10809 and emx is not necessary. [Dean Gaudet]
10811 *) WIN32: Allow .cmd as an executable extension.
10812 [Kari Likovuori <Kari.Likovuori mol.fi>] PR#2146
10814 *) Make Apache header files, and some variables, C++ friendly.
10815 [Michael Anderson's <mka redes.int.com.mx>]
10817 *) Child processes can now "signal" (by exiting with a status
10818 of APEXIT_CHILDFATAL) the parent process to abort and
10819 shutdown the server if the error in the child process was
10820 fatal enough. [Jim Jagielski]
10822 *) mod_autoindex's find_itme() was sensitive to MIME type case.
10823 [Jim Jagielski] PR#2112
10825 *) Make sure the referer_log and agent_log entries in the default httpd.conf
10826 file are also adjusted for the actual relative installation paths.
10827 [Ralf S. Engelschall] PR#2175
10829 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
10831 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
10834 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
10835 Additionally the checks for finding the vendor DSO library were moved
10836 from mod_so.c to Configure because first it needs $PLAT etc. and second
10837 mod_so already uses an abstraction layer and does not fiddle with the
10838 vendor functions itself.
10839 [Jens-Uwe Mager, Ralf S. Engelschall]
10841 *) PORT: Some optimization defines for NetBSD
10842 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
10844 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
10845 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
10847 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
10848 AIX variants should work fine, too. Even AIX 3.x should work). This is
10849 accomplished by using the free DSO emulation code from Jens-Uwe Mager
10850 which we put into a os/unix/os-dso-aix.c file.
10851 [Ralf S. Engelschall]
10853 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
10854 that we should use NET_SIZE_T == int but the include files force size_t.
10855 [Ralf S. Engelschall]
10857 *) Fix two bugs in select() handling in http_main.c.
10860 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
10861 is unset (as it is in situations like timeouts) where it is unclear
10862 whether errno is set or not. [Martin Kraemer]
10864 *) Just having APACI's localstatedir is too general and not enough for most
10865 of the systems. 1.3b6 again required manual APACI patches by package
10866 maintainers from Red Hat and FreeBSD because for their filesystem layout a
10867 little bit more flexibility in configuring the paths is needed. Hence we
10868 provide three additional configure options (--runtimedir, --logfiledir,
10869 --proxycachedir) which now can be used for more granular adjustments if
10870 --localstatedir is not enough to fit the particular needs. As a nice
10871 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
10872 [Ralf S. Engelschall]
10874 *) Make the install root for "make install" in APACI's Makefile overrideable
10875 by package authors. This way we are even more friendly to package
10876 maintainers (especially Debian and Red Hat) who build for the real prefix
10877 via "configure --prefix=/<real>" but use a different local prefix via
10878 "make root=/tmp/apache install" for rolling the package without bristling
10879 the target location on their system.
10880 [Ralf S. Engelschall]
10882 *) Workaround sed limitations in APACI's configure script by now
10883 substituting in chunks of 50 commands (because for instance HPUX's vendor
10884 sed has a limit of max. 98 commands)
10885 [Ralf S. Engelschall] PR#2136
10887 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
10888 [Ralf S. Engelschall] PR#2140
10890 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
10891 RENAMING process because they are defined as pre-processor macros instead
10892 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
10893 [Ralf S. Engelschall]
10895 *) Workaround braindead AWK's when generating ap_config.h: The split() and
10896 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
10897 [Ralf S. Engelschall] PR#2139
10899 *) Various bugfixes and cleanups for the APACI configure script:
10900 o fix IFS handling for _nested_ situation
10901 o fix Perl interpreter search: take first one found instead of last one
10902 o fix DSO consistency check
10903 o print error messages to stderr instead of stdout
10904 o add install-quiet for --shadow situation to Makefile stub
10905 o reduce complexity by avoiding sed-hacks for rule and module list loops
10906 [Ralf S. Engelschall]
10908 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
10910 *) Make sure the input field separator (IFS) shell variable is explicitly
10911 initialized correctly before _every_ `for' loop and also restored after
10912 the loops. [Ralf S. Engelschall]
10914 *) Make sure that "make install" doesn't overwrite the `mime.types' and
10915 `magic' files from an existing Apache installation. Because people often
10916 customize these for own MIME and content types.

10919 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
10920 [Peter Galbavy, Ralf S. Engelschall] PR#2109
10922 *) Fix the path to the ScoreBoardFile in the install-config target, too.
10923 [Ralf S. Engelschall] PR#2105
10925 *) Let "configure" clear out the users parameters (provided as shell
10926 variables) to avoid side-effects in "src/Configure" when the user
10927 exported them (which is not needed, but some users do it).
10928 [Ralf S. Engelschall] PR#2101
10930 *) Provide backward compatibility from some old src/Configuration.tmpl
10931 parameter names to the canonical Autoconf-style shell variable names. For
10932 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
10933 but a hint message is displayed. [Ralf S. Engelschall]
10935 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
10936 CGI scripts from an existing Apache installation.
10937 [Ralf S. Engelschall, Jim Jagielski] PR#2084
10939 *) Make `configure --compat' more "compatible" by first
10940 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
10941 second by making sure the "avoid-bristling-suffix" /apache is not
10942 appended to sysconfdir, datadir, localstatedir and includedir when
10943 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]

10952 [Ralf S. Engelschall] PR#2089
10954 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
10956 *) If you start apache with the -S command line option it will dump
10957 out the parsed vhost settings. This is useful for folks trying
10958 to figure out what is wrong with their vhost configuration.
10959 (Other dumps may be added in the future.) [Dean Gaudet]
10961 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
10962 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
10965 *) Because /usr/local/apache is the default prefix the ``configure
10966 --compat'' option no longer has to set prefix, again. This way the
10967 --compat option honors a leading --prefix option. [Lars Eilebrecht]
10969 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
10970 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
10971 to avoid "discard const" warnings. [Ralf S. Engelschall]
10973 *) If a specific handler is set for a file yet the request still
10974 ends up being handled by the default handler, log an error
10975 message before handling it. This catches things such as trying
10976 to use SSIs without mod_include enabled. [Marc Slemko]
10978 *) Fix error logging for the startup case where ap_log_error() still uses
10979 stderr as the target. Now the default log level is honored here, too.
10980 [Ralf S. Engelschall]
10982 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
10983 long" errors when generating the MODULES entry for src/Makefile
10984 [Ben Hyde, Ralf S. Engelschall]
10986 *) Make sure src/Configure doesn't complain about the old directory
10987 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
10989 Changes with Apache 1.3b6
10991 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
10993 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
10994 interface via the similar but proprietary HP/UX shl_xxx-style system
10995 calls. [Ralf S. Engelschall]
10997 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
10998 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
10999 Make. [Ralf S. Engelschall]
11001 *) ++++ THE BIG SYMBOL RENAMING ++++
11002 To avoid symbol clashes with third-party code compiled into the server,
11003 we globally applied the prefix "ap_" to the following classes of
11005 - Apache provided general functions (e.g., ap_cpystrn)
11006 - Public API functions (e.g., palloc, bgets)
11007 - Private functions which we can't make static (because of
11008 cross-object usage) but should be (e.g., new_connection)
11009 For backward source compatibility a new header file named compat.h was
11010 created which provides defines for the old symbol names and can be used
11011 by third-party module authors.
11014 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
11015 problem under SVR4 is that there is no command flag to force the linker
11016 to export the global symbols of the httpd executable therewith they are
11017 available to the DSO's. Instead of problematic hacks like creating a
11018 dummy.so file (containing dummy references to all global symbols) the
11019 httpd binary is linked against, we use a clean trick stolen from Perl 5:
11020 Placing the Apache core code itself into a DSO library named libhttpd.so.
11021 This way the global symbols _HAVE_ to be exported and thus are available
11022 to any manually loaded DSO's under runtime. To reduce the impact to the
11023 user to null we go even further and create a stub httpd executable which
11024 automatically keeps track of the DSO library loading itself and thus
11025 hides the complete mechanism from the user. Although the generation of
11026 this DSO library is automatically triggered for platforms which
11027 essentially need it (mostly all SVR4-derivates) it can be also enabled
11028 manually via the Rule SHARED_CORE. This can be interesting in the future
11029 where we perhaps exploit this libhttpd.so mechanism for providing nifty
11030 features like graceful upgrades, or whatever.
11031 [Ralf S. Engelschall, Martin Kraemer]
11033 *) Build the libraries before building the rest of the tools. [Ben Hyde]
11035 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
11036 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
11037 conventions while "clean" removes only stuff created by "all" targets,
11038 "distclean" additionally removes the stuff from the configuration
11039 process. This way "make distclean" (hence the name) provides a fresh
11040 source tree as it was for distribution.
11041 [Ralf S. Engelschall]
11043 *) Allow top-level (APACI) Makefile to break on build errors
11044 the same way the src/ subtree Makefiles breaks on them by replacing the
11045 initial APACI sed-subdir-display-kludge with a more clean
11046 variable-passing-solution: variable SDP can optionally hold the subdir
11047 prefix which is consistently used for displaying the subdir movement.
11048 This way even the top-level Makefile can stop correctly on errors as the
11049 user expects. [Ralf S. Engelschall]
11051 *) Fixed ordering of argument checks for RewriteBase directive.
11052 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
11054 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
11055 indicating that a module is being compiled for dynamic loading. Also
11056 remove #define IS_MODULE from modules and add SHARED_MODULE define
11057 to the mak/dsp files. [Alexei Kosut]
11059 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
11060 since we are now logging APLOG_WARNING by default. [Roy Fielding]
11062 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
11064 *) Add documentation file and src/Configuration.tmpl entry for the
11065 experimental mod_mmap_static module. Because although it is and marked as
11066 an experimental one it is distributed and thus should be documented and
11067 prepared for configuration the same way as all others modules.
11068 [Ralf S. Engelschall]
11070 *) Add query (-q) option to apxs support tool to be able to manually query
11071 specific settings from apxs. This is needed for instance when you
11072 manually want to access Apache's header files and you need to assemble
11073 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
11074 [Ralf S. Engelschall]
11076 *) Now src/Configure uses a fallback strategy for the shared object support
11077 on platforms where no explicit information is available: If a Perl
11078 installation exists we ask it about its shared object support and if it's
11079 the dlopen-style one we shamelessly guess the compiler and linker flags
11080 for creating shared objects from Perls knowledge. Of course, the user is
11081 warning about what we are doing and informed that he should send us
11082 the guessed flags when they work. [Ralf S. Engelschall]
11084 *) Provide APACI --without-support option to be able to disable the build
11085 and installation of the support tools from the src/support/ area.
11086 Although its useful to have these installed per default we should provide
11087 a way to compile and install without them for backward-compatibility.
11088 [Ralf S. Engelschall]
11090 *) Add of the new APache eXtenSion (apxs) support tool for building and
11091 installing modules into an _already installed_ Apache package through the
11092 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
11093 this approach actually doesn't need the Apache source tree. The
11094 (APACI-installed) server package is enough, because this now includes the
11095 Apache C header files (PREFIX/include) and the new APXS tool
11096 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
11097 module authors to build their Apache modules _OUTSIDE_ the Apache source
11098 tree while avoiding them to fiddle around with the totally platform
11099 dependend way of compiling DSO files. The tool supports all ranges of
11100 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
11101 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
11102 on-the-fly generate a minimalistic Makefile and sample module for the
11103 first step to provide both a quick success event and to demonstrate the
11104 APXS mechanism to module authors. [Ralf S. Engelschall]
11106 *) Fix core dumps in use of CONNECT in proxy.
11107 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
11109 *) Modify the log directives in httpd.conf-dist files to use CustomLog
11110 so that users have examples of how CustomLog can be used.
11113 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
11114 the Apache distribution tree. Until Apache 1.3 there was no real
11115 out-of-the-box batch-capable build and installation procedure for the
11116 complete Apache package. This is now provided by a top-level "configure"
11117 script and a corresponding top-level "Makefile.tmpl" file. The goal is
11118 to provide a GNU Autoconf-style frontend which is capable to both drive
11119 the old src/Configure stuff in batch and additionally installs the
11120 package with a GNU-conforming directory layout. Any options from the old
11121 configuration scheme are available plus a lot of new options for flexibly
11122 customizing Apache. [Ralf S. Engelschall]
11124 *) The floating point ap_snprintf code wasn't threadsafe.
11125 Had to remove the HAVE_CVT macro in order to do threadsafe
11126 calling of the ?cvt() floating point routines. [Dean Gaudet]
11128 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
11130 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
11131 [Jim Jagielski] PR#1901
11133 *) BUG: Configure was using TCC and CC inconsistently. Make sure
11134 Configure knows which CC we are using. [Jim Jagielski]
11136 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
11137 was defined in a parent directory. [Lars Eilebrecht]
11139 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
11140 a generic printf-style routine that can call arbitrary output
11141 routines. Use this to replace http_bprintf.c. Add new routines
11142 psprintf(), pvsprintf() which allocate the exact amount of memory
11143 required for a string from a pool. Use psprintf() to clean up
11144 various bits of code which used ap_snprintf()/pstrdup().
11147 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
11148 ap_snprintf() has different semantics and formatting codes than
11149 snprintf(). [Dean Gaudet]
11151 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
11152 is necessary on at least Solaris where the /etc/rc?.d scripts
11153 are run with these signals ignored, and "SIG_IGN" settings are
11154 maintained across exec().
11155 [Rein Tollevik <reint sys.sol.no>] PR#2009

11159 [Rein Tollevik <reint sys.sol.no>] PR#2010
11161 *) Fix the proxy pass-through feature of mod_rewrite for the case of
11162 existing QUERY_STRING now that mod_proxy was recently changed because of
11163 the new URL parsing stuff. [Ralf S. Engelschall]
11165 *) A few changes to scoreboard definitions which helps gcc generate
11166 better code. [Dean Gaudet]
11168 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
11169 be a signed bitfield. So mark a few bitfields as signed to
11170 ensure correct code. [Dean Gaudet]
11172 *) The default for HostnameLookups was changed to Off, but there
11173 was a problem and it wasn't taking effect. [Dean Gaudet]
11175 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
11178 *) After a SIGHUP the listening sockets in the parent weren't
11179 properly marked for closure on fork().
11180 [Jürgen Keil <jk tools.de>] PR#2000
11182 *) Allow %2F in two situations: 1) it is in the query part of the URI,
11183 therefore not exposed to %2F -> '/' translations and 2) the request
11184 is a proxy request, so we're not dealing with a local resource anyway.
11185 Without this, the proxy would fail to work for any URL's with
11186 %2f in them (occurs quite often in
11187 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
11189 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
11191 *) Make the shared object compilation command more portable by avoiding
11192 the direct combination of `-c' & `-o' which is not honored by some
11193 compilers like UnixWare's cc. [Ralf S. Engelschall]
11195 *) WIN32: the proxy was creating filenames missing the last four
11196 characters. While this normally doesn't stop anything from
11197 working, it can result in extra collisions.
11198 [Tim Costello <tjcostel socs.uts.edu.au>] PR#1890
11200 *) Now mod_proxy uses the response string (in addition to the response status
11201 code) from the already used FTP SIZE command to setup the Content-Length
11202 header if available. [Ralf S. Engelschall] PR#1183
11204 *) Reanimated the (still undocumented) proxy receive buffer size directive:
11205 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
11206 name was really too generic, added documentation for this directive to
11207 the mod_proxy.html and corrected the hyperlink to it in the
11208 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
11210 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
11211 faster [Martin Kraemer]
11213 *) Make Configure die when you give it an unknown command switch.
11216 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
11217 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
11218 and per default compiled support programs have manual pages - just to
11219 document our stuff a little bit more and to be able to do really
11220 Unix-like installations ;-) [Ralf S. Engelschall]
11222 *) Major cleanups to the Configure script to make it and its generated
11223 Makefiles again readable and maintainable: add SRCDIR option, removed
11224 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
11225 generated sections, consequently added Makefile headers with inheritance
11226 information, added subdir movement messages for easier following where
11227 the build process currently stays (more verbose then standard Make, less
11228 verbose than GNU make), same style to comments in the Configure script,
11229 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
11231 *) Add the new ApacheBench program "ab" to src/support/: This is derived
11232 from the ZeusBench benchmarking program and can be used to determine the
11233 response performance of an Apache installation. This version is
11234 officially licensed with Zeus Technology, Ltd. See the license agreement
11235 statements in <199803171224.NAA24547 en1.engelschall.com> in apache-core.
11236 [Ralf S. Engelschall]
11238 *) API: Various core functions that are definately not part of the API
11239 have been made static, and a few have been marked API_EXPORT. Still
11240 more have been marked CORE_EXPORT and are not intended for general
11241 use by modules. [Doug MacEachern, Dean Gaudet]
11243 *) mod_proxy was not clearing the Proxy-Connection header from
11244 requests; now it does. This did not violate any spec, however
11245 causes poor interactions when you are talking to remote proxies.
11246 [Marc Slemko] PR#1741
11248 *) Various cleanups to the command line interface and manual pages.
11249 [Ralf S. Engelschall]
11251 *) cfg_getline() was not properly handling lines that did not end
11252 with a line termination character. [Marc Slemko] PR#1869, 1909
11254 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
11256 *) Clean up some undocumented behavior of mod_setenvif related to
11257 "merging" two SetEnvIf directives when they match the same header
11258 and regex. Document that mod_setenvif will perform comparisons in
11259 the order they appear in the config file. Optimize mod_setenvif by
11260 doing more work at config time rather than at runtime.
11263 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
11264 to allow for modules to overrule them and to reduce redefinition
11265 warnings [Jim Jagielski]
11267 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
11270 *) Making the hard-coded cross-module function call mime_find_ct() (from
11271 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
11272 checking is really called even for proxy requests except for URLs with
11273 HTTP schemes (because there we can optimize by not running the type
11274 checking hooks due to the fact that the proxy gets the MIME Content-type
11275 from the remote host later). This change cleans up mod_mime by removing
11276 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
11277 especially unbundles mod_proxy and mod_mime. This way they both now can
11278 be compiled as shared objects and are no longer tied together.
11279 [Ralf S. Engelschall]
11281 *) util.c cleanup and speedup. [Dean Gaudet]
11283 *) API: Clarification, pstrndup() will always copy n bytes of the source
11284 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
11286 *) Mark module command_rec and handler_rec structures const so that they
11287 end up in the read-only data section (and are friendlier to systems
11288 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
11290 *) Add check to the "Port" directive to make sure the specified
11291 port is in the appropriate range. [Ben Hyde]
11293 *) Performance improvements to invoke_handler().
11294 [Dmitry Khrustalev <dima bog.msu.su>]
11296 *) Added support for building shared objects even for library-style modules
11297 (which are built from more than one object file). This now provides the
11298 ability to build mod_proxy as a shared object module. Additionally
11299 modules like mod_example are now also supported for shared object
11300 building because the generated Makefiles now no longer assume there is at
11301 least one statically linked module. [Ralf S. Engelschall]
11303 *) API: Clarify usage of content_type, handler, content_encoding,
11304 content_language and content_languages fields in request_rec. They
11305 must always be lowercased; and the strings pointed to shouldn't
11306 be modified (you must copy them to modify them). Fix a few bugs
11307 related to this. [Dean Gaudet]
11309 *) API: Clarification: except for RAW_ARGS, all command handlers can
11310 treat the char * parameters as permanent, and modifiable. There
11311 is no need to pstrdup() them. Clean up some needless pstrdup().
11314 *) Now mod_so keeps track of which module shared objects with which names
11315 are loaded and thus avoids multiple loading and unloading and irritating
11316 error_log messages. [Ralf S. Engelschall]
11318 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
11319 environment variable in the apache core. But that tweaking interferes
11320 with mod_setenv. So don't tweak if the user has specified an explicit
11321 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888
11323 *) rputs() did not calculate r->sent_bodyct properly.
11324 [Siegmund Stirnweiss <siegst kat.ina.de>] PR#1900
11326 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
11327 name, or left unset if this value is unavailable. Apache was setting
11328 it to the IP address when unavailable.
11329 [Tony Finch <fanf demon.net>] PR#1925
11331 *) Various improvements to the configuration and build support for compiling
11332 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
11333 OSF1 support with GCC and vendor compilers was added. This way shared
11334 object support is now provided out-of-the-box for FreeBSD, Linux,
11335 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
11336 [Ralf S. Engelschall]
11338 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
11339 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
11340 and USE_OS2_SCOREBOARD. [Dean Gaudet]
11342 *) Fix one more special locking problem for RewriteMap programs in
11343 mod_rewrite: According to the documentation of flock(), "Locks are on
11344 files, not file descriptors. That is, file descriptors duplicated
11345 through dup(2) or fork(2) do not result in multiple instances of a lock,
11346 but rather multiple references to a single lock. If a process holding a
11347 lock on a file forks and the child explicitly unlocks the file, the
11348 parent will lose its lock.". To overcome this we have to make sure the
11349 RewriteLock file is opened _AFTER_ the childs were spawned which is now
11350 the case by opening it in the child_init instead of the module_init API
11351 hook. [Ralf S. Engelschall] PR#1029
11353 *) Change to Location and LocationMatch semantics. LocationMatch no
11354 longer lets a single slash match multiple adjacent slashes in the
11355 URL. This change is for consistency with RewriteRule and
11356 AliasMatch. Multiple slashes have meaning in URLs that they do
11357 not have in (some) filesystems. Location on the other hand can
11358 be considered a shorthand for a more complicated regex, and it
11359 does match multiple slashes with a single slash -- which is
11360 also consistent with the Alias directive.

11363 *) Fix bug with mod_mime_magic causing certain files, including files
11364 of length 0, to result in no response from the server.
11367 *) The Configure script now generates src/include/ap_config.h which
11368 contains the set of defines used when Apache is compiled on a platform.
11369 This file can then be included by external modules before including
11370 any Apache header files in case they are being built separately from
11371 Apache. Along with this change, a couple of minor changes were
11372 made to make Apache's #defines coexist peacefully with any autoconf
11373 defines an external module might have. [Rasmus Lerdorf]
11375 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
11376 but without any RewriteXXXXX directives. Here mod_rewrite is given no
11377 chance by the API to initialize its per-server configuration and thus
11378 receives the wrong one from the main server. This is now avoided by
11379 remembering the server together with the config structure while
11380 configuring and later assuming there is no config when we see a
11381 difference between the remembered server and the one calling us.
11382 [Ralf S. Engelschall] PR#1790
11384 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
11385 is automatically disabled under configure time when the dbm_xxx functions
11386 are not available. Second, two heavy source code errors in the DBM
11387 support code were fixed. This makes DBM RewriteMap's usable again after
11388 a long time of brokenness. [Ralf S. Engelschall] PR#1696
11390 *) Now all configuration files support Unix-style line-continuation via
11391 the trailing backslash ("\") character. This enables us to write down
11392 complex or just very long directives in a more readable way. The
11393 backslash character has to be really the last character before the
11394 newline and it has not been prefixed by another (escaping) backslash.

11410 depending on the rev of Solaris and what mixture of modules
11411 are in use. So it has been disabled, and Solaris is back to
11412 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
11413 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
11414 up static content only servers. Or it may fail unpredictably.

11417 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
11420 *) API: Rewrite of absoluteURI handling, and in particular how
11421 absoluteURIs match vhosts. Unless a request is a proxy request, a
11422 "http://host" url is treated as if a similar "Host:" header had been
11423 supplied. This change was made to support future HTTP/1.x protocols
11424 which may require clients to send absoluteURIs for all requests.
11426 In order to achieve this change subtle changes were made to the API. In a
11427 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
11428 that the unmodified uri can be retrieved easily. r->proxyreq is not set
11429 by the core, modules must set it during the post_read_request or
11430 translate_names phase.
11432 Plus changes to the virtualhost test suite for absoluteURI testing.
11434 This fixes several bugs with the proxy proxying requests to vhosts
11435 managed by the same httpd.
11438 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
11439 code from mod_rewrite. The vhost matching is now performed by a
11440 globally available function matches_request_vhost(). [Dean Gaudet]

11456 *) API: A new source module main/util_uri.c; It contains a routine
11457 parse_uri_components() and friends which breaks a URI into its component
11458 parts. These parts are stored in a uri_components structure called
11459 parsed_uri within each request_rec, and are available to all modules.
11460 Additionally, an unparse routine is supplied which re-assembles the URI
11461 components back to an URI, optionally hiding the username:password@ part
11462 from ftp proxy requests, and other useful routines. Within the structure,
11463 you find on a ready-for-use basis:
11464 scheme; /* scheme ("http"/"ftp"/...) */
11465 hostinfo; /* combined [user[:password]@]host[:port] */
11466 user; /* user name, as in http://user:passwd@host:port/ */
11467 password; /* password, as in http://user:passwd@host:port/ */
11468 hostname; /* hostname from URI (or from Host: header) */
11469 port_str; /* port string (integer representation is in "port") */
11470 path; /* the request path (or "/" if only scheme://host was given) */
11471 query; /* Everything after a '?' in the path, if present */
11472 fragment; /* Trailing "#fragment" string, if present */
11473 This is meant to serve as the platform for *BIG* savings in
11474 code complexity for the proxy module (and maybe the vhost logic).
11477 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
11478 ${map:key}) available for all location where a string is created in
11479 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

11481 possible expansions are consequently usable at all string creation
11482 locations. [Ralf S. Engelschall]

11485 and not 1) and the per-virtual-server merging of directives. Now all
11486 directives except `RewriteEngine' and `RewriteOption' are either
11487 completely overridden (default) or completely inherited (when
11488 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

11519 type but with a special post-processing for the looked-up value: It
11520 parses it into alternatives according to `|' chars and then only one
11521 particular alternative is chosen randomly (this is an essential
11522 functionality needed for balancing between backend-servers when using
11523 Apache as a Reverse Proxy. The looked up value here is a list of
11524 servers). Second, `int' with the built-in maps named `tolower' and
11525 `toupper' which can be used to map URL parts to a fixed case (this is an
11526 essential feature to fix the case of server names when doing mass
11527 virtual-hosting with the help of mod_rewrite instead of using

11685 references in Makefiles have been changed to the simpler -Iinclude
11686 instead. In addition to simplifying the build a little bit, this
11687 also makes it clear when a module is referencing something in a
11688 other than kosher manner (e.g., the proxy including mod_mime.h).
11689 Module-private header files (the proxy, mod_mime, the regex library,

11720 *) mod_unique_id was erroneously generating a second unique id when
11721 an internal redirect occured. Such redirects occur, for example,
11722 when processing a DirectoryIndex match. [Dean Gaudet]
11724 *) API: table_add, table_merge, and table_set include implicit pstrdup()
11725 of the key and value. But in many cases this is not required
11726 because the key/value is a constant, or the value has been built
11727 by pstrcat() or other similar means. New routines table_addn,
11728 table_mergen, and table_setn have been added to the API, these
11729 routines do not pstrdup() their arguments. The core code and
11730 standard modules were changed to take advantage of these routines.
11731 The resulting server is up to 20% faster in some situations.
11733 Note that it is easy to get code subtly wrong if you pass a key/value
11734 which is in a pool other than the pool of the table. The only
11735 safe thing to do is to pass key/values which are in the pool of
11736 the table, or in one of the ancestors of the pool of the table.
11737 i.e. if the table is part of a subrequest, a value from the main
11738 request's pool is OK since the subrequest pool is a sub_pool of the
11739 main request's pool (and therefore has a lifespan at most as long as
11740 the main pool). There is debugging code which can detect improper
11741 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
11742 [Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet]

11757 *) API: "typedef array_header table" removed from alloc.h, folks should
11758 have been writing to use table as if it were an opaque type, but even
11759 some standard modules got this wrong. By changing the definition
11760 to "typedef struct table table" module authors will receive compile
11761 time warnings that they're doing the wrong thing. This change
11762 facilitates future changes with more sophisticated table
11763 structures. Specifically, module authors should be using table_elts()
11764 to get access to an array_header * for the table. [Dean Gaudet]
11766 *) API: Renamed new_connection() to avoid namespace collision with LDAP
11767 library routines. [Ken Coar, Rasmus Lerdorf]
11769 *) WIN32: mod_speling is now available on the Win32 platform.
11772 *) For clarity the following compile time definition was changed:
11774 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
11776 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
11777 and not be a general notice that the OS has mmap(). Now the
11778 HAVE_MMAP/SHMGET #defines strictly are informational that the
11779 OS has that method of shared memory; the type to use for
11780 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
11781 and USE_SHMGET_SCOREBOARD). This allows outside modules to
11782 determine if shared memory is available and allows Apache
11783 to determine the best method to use for the scoreboard.

11863 properly null terminated. [Marc Slemko]
11865 *) The "Connection" header could be sent back with multiple "close"
11866 tokens. Not an error, but a waste.
11867 [<Ronald.Tschalaer psi.ch>] PR#1683
11869 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
11870 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
11872 *) "basic" auth needs a case-insensitive comparison.
11873 [<Ronald.Tschalaer psi.ch>] PR#1666
11875 *) For maximum portability, the environment passed to CGIs should
11876 only contain variables whose names match the regex
11877 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
11878 underscores over any character outside the regex. This
11879 affects HTTP_* variables, in a way that should be backward
11880 compatible for all the standard headers; and affects variables
11881 set with SetEnv/BrowserMatch and similar directives.
11884 *) mod_speling returned incorrect HREF's when an ambigous match

11917 possible buffer overflows and a possible infinite loop.

11920 *) SECURITY: Numerous changes to mod_imap in a general cleanup
11921 including fixing a possible buffer overflow. [Dean Gaudet]
11923 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
11924 (connections are not dropped). Code can handle graceful restarts
11925 (but there is as yet no way to signal this to Apache). Various
11926 other cleanups. [Paul Sutton]
11928 *) The aplog_error changes specific to 1.3 introduced a buffer
11929 overrun in the (now legacy) log_printf function. Fixed.
11932 *) mod_digest didn't properly deal with proxy authentication. It
11933 also lacked a case-insensitive comparision of the "Digest"

11967 *) send_fd_length() did not calculate total_bytes_sent properly.
11968 [Ben Reser <breser regnow.com>] PR#1366
11970 *) The bputc() macro was not properly integrated with the chunking
11971 code; in many cases modules using bputc() could cause completely
11972 bogus chunked output. (Typically this will show up as problems
11973 with Internet Explorer 4.0 reading a page, but other browsers
11974 having no problem.) [Dean Gaudet]
11976 *) Create LARGE_WRITE_THRESHOLD define which determines how many
11977 bytes have to be supplied to bwrite() before it will consider
11978 doing a writev() to assemble multiple buffers in one system
11979 call. This is critical for modules such as mod_include,
11980 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
11981 strings in some cases. The result would be extra effort
11982 setting up writev(), and in many cases extra effort building
11983 chunks. The default is 31, it can be overriden at compile
11984 time. [Dean Gaudet]
11986 *) Move the gid switching code into the child so that log files
11987 and pid files are opened with the root gid.

11994 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
11995 so the functionality is available to applications other than the

12052 now have a title in which the path components are clickable and allow

12100 *) PORT: Recent changes made it necessary to add explicit prototype
12101 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
12103 *) It was necessary to distinguish between resources which are
12104 allocated in the parent, for cleanup in the parent, and resources
12105 which are allocated in each child, for cleanup in each child.
12106 A new pool was created which is passed to the module child_init
12107 and child_exit functions; modules are free to register per-child
12108 cleanups there. This fixes a bug with reliable piped logs.
12111 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
12112 unless it was also doing FancyIndexes, but it displayed the
12113 HeaderName file at the top under all circumstances. It now shows
12114 the ReadmeName file for simple indices, too, as it should.
12117 *) http_core was mmap()ing even in cases where it wasn't going to
12118 read the file. [Ben Hyde <bhyde gensym.com>]
12120 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
12121 Now the rewriting engine (the heart of mod_rewrite) is organized more
12122 straight-forward, first time well documented and reduced to the really
12123 essential parts. All redundant cases were stripped off and processing now
12124 is the same for both per-server and per-directory context with only a
12125 minimum difference (the prefix stripping in per-dir context). As a
12126 side-effect some subtle restrictions and two recently discovered problems
12127 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
12128 context and restrictions on the substitution URL on redirects.
12129 Additionally some minor source cleanups were done.

12286 *) TestCompile was not passing $LIBS [Dean Gaudet]
12288 *) Makefile.tmpl was not using $CFLAGS in the link phase.
12291 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
12292 rudimentary memory debugger which can be used on live servers with
12293 low impact -- it sets all allocated and freed memory bytes to 0xa5.
12294 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
12295 and free() for each object. This is far more expensive and should
12296 only be used for testing with tools such as Electric Fence and
12297 Purify. See main/alloc.c for more details. [Dean Gaudet]

12304 From a given ip:port, regardless what the Host: header is, you can
12305 only reach the vhosts defined on that ip:port. The precedence of
12306 vhosts was reversed to match other precedences in the config --
12307 the earlier vhosts override the later vhosts. All vhost matching was
12308 moved into http_vhost.[ch]. [Dean Gaudet]
12310 *) ap_inline can be used to force inlining. GNUC __attribute__() can
12311 be used for whatever reason is appropriate (i.e. format() warnings

12353 "RedirectMatch /advertiser/(.*) $1" is now permitted.

12378 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
12379 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
12380 bytes before writing, but it will never split a log entry across a
12381 buffer boundary. [Dean Gaudet]
12383 *) API: the short_score record has been split into two pieces, one which
12384 the parent writes on, and one which the child writes on. As part of
12385 this change the get_scoreboard_info() function was removed, and
12386 scoreboard_image was exported. This change fixes a race condition
12387 in file based scoreboard systems, and speeds up changes involving the
12388 scoreboard in earlier 1.3 development. [Dean Gaudet]
12390 *) API: New register_other_child() API (see http_main.h) which allows
12391 modules to register children with the parent for maintenance. It
12392 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
12394 *) API: New piped_log API (see http_log.h) which implements piped logs,
12395 and will use register_other_child to implement reliable piped logs
12396 when it is available. The reliable piped logs part can be disabled
12397 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
12398 logs is only available on Unix. [Dean Gaudet]
12400 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
12401 meets_conditions(). This allows conditional HTTP selection to be
12402 handled separately from the storing of the header fields, and provides
12403 the ability for CGIs to set their own ETags for conditional checking.
12404 [Ken Coar, Roy Fielding] PR#895
12406 *) Changes to mod_log_config to allow naming of format strings.
12407 Format nicknames are defined with "LogFormat fmt nickname", and can
12408 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
12411 *) New module, "mod_speling", which can help find files even when
12412 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
12414 *) API: New function child_terminate() triggers the child process to
12415 exit, while allowing the child finish what it needs to for the
12416 current request first.
12417 [Doug MacEachern, Alexei Kosut]
12419 *) Windows now defaults to using full status reports with mod_status.
12420 [Alexei Kosut] PR #1094
12422 *) *Really* disable all mod_rewrite operations if the engine is off.
12423 Some things (like RewriteMaps) were checked/performed even if they
12424 weren't supposed to be. [Ken Coar] PR #991
12426 *) Implement a new timer scheme which eliminates the need to call alarm() all
12427 the time. Instead a counter in the scoreboard for each child is used to
12428 show when the child has made forward progress. The parent samples this
12429 counter every scoreboard maintenance cycle, and issues SIGALRM if no
12430 progress has been made in the timeout period. This reduces the static
12431 request best-case syscall count to 22 from 29. This scheme is only
12432 used by systems with memory-based scoreboards. [Dean Gaudet]
12434 *) The proxy now properly handles CONNECT requests which are sent
12435 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
12437 *) A script called apachectl has been added to the support
12438 directory. This script allows you to do things such as
12439 "apachectl start" and "apachectl restart" from the command
12440 line. [Marc Slemko]
12442 *) Modules and core routines are now put into libraries, which
12443 simplifies the link line tremendously (among other advantages).
12446 *) Some of the MD5 names defined in Apache have been renamed to have
12447 an `ap_' prefix to avoid conflicts with routines supplied by
12448 external libraries. [Ken Coar]
12450 *) Removal of mod_auth_msql.c from the distribution. There are many
12451 other options for databases today. Rather than offer one option,
12452 offer none at this time. mod_auth_msql and other SQL database
12453 authentication modules can be found at the Apache Module Registry.
12454 http://modules.apache.org/ It would be nice to offer a generic
12455 mod_auth_sql option in the near future.
12457 *) PORT: BeOS support added [Alexei Kosut]
12459 *) Configure no longer accepts the -make option, since it creates
12460 Makefile on the fly based on Makefile.tmpl and Configuration.
12462 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
12463 of forcibly killing off all its processes and exiting without
12464 cleaning up. [Alexei Kosut]
12466 *) API: A new field in the request_rec, r->mtime, has been added to
12467 avoid gratuitous parsing of date strings. It is intended to hold
12468 the last-modified date of the resource (if applicable). An
12469 update_mtime() routine has also been added to advance it if
12470 appropriate. [Roy Fielding, Ken Coar]
12472 *) SECURITY: If a htaccess file can not be read due to bad permissions,
12473 deny access to the directory with a HTTP_FORBIDDEN. The previous
12474 behavior was to ignore the htaccess file if it could not be read.
12475 This change may make some setups with unreadable htaccess files
12476 stop working. [Marc Slemko] PR#817
12478 *) Add aplog_error() providing a mechanism to define levels of
12479 verbosity to the server error logging. This addition also provides
12480 the ability to log errors using syslogd. Error logging is configurable
12481 on a per-server basis using the LogLevel directive. Conversion
12482 of log_*() in progress. [Randy Terbush]
12484 *) Further enhance aplog_error() to not log filename, line number, and
12485 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
12487 *) WIN32: Canonicalise filenames under Win32. Short filenames are
12488 converted to long ones. Backslashes are converted to forward
12489 slashes. Case is converted to lower. Parts of URLs that do not
12490 correspond to files are left completely alone. [Ben Laurie]
12492 *) PORT: 2 new OSs added to the list of ports:
12493 Encore's UMAX V: Arieh Markel <amarkel encore.com>
12494 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
12496 *) Add the server version (SERVER_VERSION macro) to the "server
12497 configured and running" entry in the error_log. Also build an
12498 object file at link-time that contains the current time
12499 (SERVER_BUILT global const char[]), and include that in the
12500 message. [Ken Coar]
12502 *) Set r->headers_out when sending responses from the proxy.
12503 This fixes things such as the logging of headers sent from
12504 the proxy. [Marc Slemko] PR#659
12506 *) support/httpd_monitor is no longer distributed because the
12507 scoreboard should not be file based if at all possible. Use
12508 mod_status to see current server snapshot.
12510 *) (set_file_slot): New function, allowing auth directives to be
12511 independent of the server root, so the server documents can be
12512 moved to a different directory or machine more easily.
12513 [David J. MacKenzie]
12515 *) If no TransferLog is given explicitly, decline
12516 to log. This supports coexistence with other logging modules,
12517 such as the custom one that UUNET uses. [David J. MacKenzie]
12519 *) Check for titles in server-parsed HTML files.
12520 Ignore leading newlines and returns in titles. The old behavior
12521 of replacing a newline after <title> with a space causes the
12522 title to be misaligned in the listing. [David J. MacKenzie]
12524 *) Change mod_cern_meta to be configurable on a per-directory basis.
12525 [David J. MacKenzie]
12527 *) Add 'Include' directive to allow inclusion of configuration
12528 files within configuration files. [Randy Terbush]
12530 *) Proxy errors on connect() are logged to the error_log (nothing
12531 new); now they include the IP address and port that failed
12532 (*that's* new). [Ken Coar, Marc Slemko] PR#352
12534 *) Various architectures now define USE_MMAP_FILES which causes
12535 the server to use mmap() for static files. There are two
12536 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
12537 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
12538 number of bytes written in one cycle from a single mmap()d object,
12539 default 32768). [Dean Gaudet]
12541 *) API: Added post_read_request API phase which is run right after reading
12542 the request from a client, or right after an internal redirect. It is
12543 useful for modules setting environment variables that depend only on
12544 the headers/contents of the request. It does not run during subrequests
12545 because subrequests inherit pretty much everything from the main
12546 request. [Dean Gaudet]
12548 *) Added mod_unique_id which is used to generate a unique identifier for
12549 each hit, available in the environment variable UNIQUE_ID.
12552 *) init_modules is now called after the error logs have been opened. This
12553 allows modules to emit information messages into the error logs.
12556 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
12557 information for case where proxy module is not available. [Marc Slemko]
12559 *) PORT: Apache has need for mutexes to serialize its children around
12560 accept. In prior versions either fcntl file locking or flock file
12561 locking were used. The method is chosen by the definition of
12562 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
12563 and FLOCK for flock(). New options have been added:
12564 - SYSVSEM to use System V style semaphores
12565 - PTHREAD to use POSIX threads (appears to work on Solaris only)
12566 - USLOCK to use IRIX uslock
12567 Based on timing various techniques, the following changes were made
12569 - Linux 2.x uses flock instead of fcntl
12570 - Solaris 2.x uses pthreads
12571 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
12572 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
12573 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
12574 Martijn Koster <m.koster pobox.com>]
12576 *) PORT: The semantics of accept/select make it very desirable to use
12577 mutexes to serialize accept when multiple Listens are in use. But
12578 in the case where only a single socket is open it is sometimes
12579 redundant to serialize accept(). Not all unixes do a good job with
12580 potentially dozens of children blocked on accept() on the same
12581 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
12582 the server will avoid serialization when listening on only one socket,
12583 and use serialization when listening on multiple sockets.
12584 [Dean Gaudet] PR#467
12586 *) Configure changes: TestLib replaced by TestCompile, which has
12587 some additional capability (such as doing a sanity check of
12588 the compiler and flags selected); the version of Solaris is now
12589 available via the #define value of SOLARIS2; IRIX n32bit libs
12590 now supported and selectable by new Configuration Rule: IRIXN32;
12591 We no longer default to -O2 optimization. [Jim Jagielski]
12593 *) Updated Configure: Configuration now uses AddModule to specify
12594 module source or binary file location, relative to src directory.
12595 Modules can be dropped into modules/extra, or in their own
12596 directory, and modules can come with a Makefile or Configure can
12597 create one. Modules can add compiler or library information to
12598 generated Makefiles. [Paul Sutton]
12600 *) Source core re-organisation: distributed modules are now in
12601 modules/standard. All other source code is in main. OS-specific
12602 code is in os/{unix,emx,win32} directories. [Paul Sutton]
12604 *) mod_browser has been removed, since it's replaced by mod_setenvif.
12607 *) Fix another long-standing bug in sub_req_lookup_file where it would
12608 happily skip past access checks on subdirectories looked up with
12609 relative paths. (It's used by mod_dir, mod_negotiation,
12610 and mod_include.) [Dean Gaudet]
12612 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
12613 N is the number of <Directory> sections, and M is the number of
12614 components in the filename of an object.
12616 To achieve this optimization the following config changes were made:
12617 - Wildcards (* and ?, not the regex forms) in <Directory>s,
12618 <Files>s, and <Location>s now treat a slash as a special
12619 character. For example "/home/*/public_html" previously would
12620 match "/home/a/andrew/public_html", now it only matches things
12621 like "/home/bob/public_html". This mimics /bin/sh behaviour.
12622 - It's possible now to use [] wildcarding in <Directory>, <Files>
12624 - Regex <Directory>s are applied after all non-regex <Directory>s.
12628 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
12629 and corrupted paths. [Dean Gaudet]
12631 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
12632 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
12633 be accessed now via backreferences $1..$9 in RewriteConds test-against
12634 strings in addition to RewriteRules subst string. Second the grouped
12635 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
12636 via backreferences %1..%9 both in following RewriteCond test-against
12637 strings and RewriteRules subst string. This provides maximum flexibility
12638 through the use of backreferences.
12639 Additionally the rewriting engine was cleaned up by putting common
12640 code to the new expand_backrefs_inbuffer() function.
12641 [Ralf S. Engelschall]
12643 *) When merging the main server's <Directory> and <Location> sections into
12644 a vhost, put the main server's first and the vhost's second. Otherwise
12645 the vhost can't override the main server. [Dean Gaudet] PR#717
12647 *) The <Directory> code would merge and re-merge the same section after
12648 a match was found, possibly causing problems with some modules.
12651 *) ip-based vhosts are stored and queried using a hashing function, which
12652 has been shown to improve performance on servers with many ip-vhosts.
12653 Some other changes had to be made to accommodate this:
12654 - the * address for vhosts now behaves like _default_
12655 - the matching process now is:
12656 - match an ip-vhost directly via hash (possibly matches main
12658 - if that fails, just pretend it matched the main server
12659 - if so far only the main server has been matched, perform
12660 name-based lookups (ServerName, ServerAlias, ServerPath)
12661 *only on name-based vhosts*
12662 - if they fail, look for _default_ vhosts
12663 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
12665 *) dbmmanage overhaul:
12666 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
12667 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
12668 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
12669 - provide better seed for rand
12670 - prompt for password as per getpass(3) (turn off echo, read from
12672 - use "newstyle" crypt based on $Config{osname} ($^O)
12673 - will not add a user if already in database, use new `update' command
12675 - added `check' command to check a users' password
12676 - added `import' command to convert existing password text-files or
12677 dbm files exported with `view'
12678 - more descriptive usage, general cleanup, 'use strict' clean, etc.
12681 *) Added psocket() which is a pool form of socket(), various places within
12682 the proxy weren't properly blocking alarms while registering the cleanup
12683 for its sockets. bclose() now uses pclose() and pclosesocket(). There
12684 was a bug where the client socket was being close()d twice due a still
12685 registered cleanup. [Dean Gaudet]
12687 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
12690 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
12691 [Jason Venner <jason idiom.com>] PR#667
12693 *) Enable ``=""'' for RewriteCond directives to match against
12694 the empty string. This is the preferred way instead of ``^$''.
12695 [Ralf S. Engelschall]
12697 *) Fixed an infinite loop in mod_imap for references above the server root
12698 [Dean Gaudet] PR#748
12700 *) mod_proxy now has a ReceiveBufferSize directive, similar to
12701 SendBufferSize, so that the TCP window can be set appropriately
12702 for LFNs. [Phillip A. Prindeville]
12704 *) mod_browser has been replaced by the more general mod_setenvif
12705 (courtesy of Paul Sutton). BrowserMatch* directives are still
12706 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
12707 UnSetEnvIfZero directives. [Ken Coar]
12709 *) "HostnameLookups double" forces double-reverse DNS to succeed in
12710 order for remote_host to be set (for logging, or for the env var
12711 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
12714 *) mod_access overhaul:
12715 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
12716 and cidr syntax (i.e. 10.1.0.0/16). PR#762
12717 - Critical path was sped up by pre-computing a few things at config time.
12718 - The undocumented syntax "allow user-agents" was removed,
12719 the replacement is "allow from env=foobar" combined with mod_browser.
12720 - When used with hostnames it now forces a double-reverse lookup
12721 no matter what the directory settings are. This double-reverse
12722 doesn't affect any of the other routines that use the remote
12723 hostname. In particular it's still passed to CGIs and the log
12724 without the double-reverse check. Related PR#860.
12727 *) When a large bwrite() occurs (larger than the internal buffer size),
12728 while there is already something in the buffer, apache will combine
12729 the large write and the buffer into a single writev(). (This is
12730 in anticipation of using mmap() for reading files.)
12733 *) In obscure cases where a partial socket write occurred while chunking,
12734 Apache would omit the chunk header/footer on the next block. Cleaned
12735 up other bugs/inconsistencies in error conditions in buff.c. Fixed
12736 a bug where a long pause in DNS lookups could cause the last packet
12737 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
12739 *) API: Added child_exit function to module structure. This is called
12740 once per "heavy-weight process" just before a server child exit()'s
12741 e.g. when max_requests_per_child is reached, etc.
12742 [Doug MacEachern, Dean Gaudet]
12744 *) mod_include cleanup showed that handle_else was being used to handle
12745 endif. It didn't cause problems, but it was cleaned up too.
12748 *) mod_cern_meta would attempt to find meta files for the directory itself
12749 in some cases, but not in others. It now avoids it in all cases.
12752 *) mod_mime_magic would core dump if there was a decompression error.

12759 by the various fields (name, size, et cetera), either in ascending
12760 or descending order. Just click on the column header. [Ken Coar]
12762 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
12763 CPUs like the Alpha. Apache still stores ints in pointers, but that's
12764 the relatively safe direction. [Dean Gaudet] PR#344
12766 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
12767 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
12769 *) child_main avoids an unneeded call to select() when there is only one
12770 listening socket. [Dean Gaudet]
12772 *) In the event that the server is starved for idle servers it will
12773 spawn 1, then 2, then 4, ..., then 32 servers each second,
12774 doubling each second. It'll also give a warning in the errorlog
12775 since the most common reason for this is a poor StartServers
12776 setting. The define MAX_SPAWN_RATE can be used to raise/lower
12777 the maximum. [Dean Gaudet]
12779 *) Apache now provides an effectively unbuffered connection for
12780 CGI scripts. This means that data will be sent to the client
12781 as soon as the CGI pauses or stops output; previously, Apache would
12782 buffer the output up to a fixed buffer size before sending, which
12783 could result in the user viewing an empty page until the CGI finished
12784 or output a complete buffer. It is no longer necessary to use an
12785 "nph-" CGI to get unbuffered output. Given that most CGIs are written
12786 in a language that by default does buffering (e.g. perl) this
12787 shouldn't have a detrimental effect on performance.
12789 "nph-" CGIs, which formerly provided a direct socket to the client
12790 without any server post-processing, were not fully compatible with
12791 HTTP/1.1 or SSL support. As such they would have had to implement
12792 the transport details, such as encryption or chunking, in order
12793 to work properly in certain situations. Now, the only difference
12794 between nph and non-nph scripts is "non-parsed headers".

12819 [Igor N Kovalenko <infoh mail.wplus.net>]
12821 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to

12860 braindead SunOS 4.1.x, allow env variables to be set even on rules with
12861 no substitution, bugfixed situations where HostnameLookups is off, made
12862 mod_rewrite more thread-safe for NT port and fixed problem when creating
12863 an empty query string via "xxx?".
12864 This update also removes the copyright of Ralf S. Engelschall,
12865 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
12866 exclusively copyrighted by the Apache Group now. This happened because
12867 the author now has gifted mod_rewrite exclusively to the Apache Group and
12868 no longer maintains an external version.
12869 [Ralf S. Engelschall]
12871 *) API: Added child_init function to module structure. This is called
12872 once per "heavy-weight process" before any requests are handled.
12873 See http_config.h for more details. [Dean Gaudet]
12875 *) Anonymous_LogEmail was logging on each subrequest.
12876 [Dean Gaudet] PR#421, 868
12878 *) API: Added is_initial_req() which tests if the request being
12879 processed is the initial request, or a subrequest.
12882 *) Extended SSI (mod_include) now handles additional relops for
12883 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
12885 *) Configure fixed to correctly propagate user-selected options and
12886 settings (such as CC and OPTIM) to Makefiles other than
12887 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
12889 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
12890 directory indices to start with the contents of the HeaderName file
12891 if there is one. If there isn't one, the behaviour is unchanged.
12892 [Ken Coar, Roy Fielding, Andrey A. Chernov]
12894 *) WIN32: Modules can now be dynamically loaded DLLs using the
12895 LoadModule/LoadFile directives. Note that module DLLs must be
12896 compiled with the multithreaded DLL version of the runtime library.
12897 [Alexei Kosut and Ben Laurie]
12899 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
12900 This allows the admin to completely remove automatic indexing
12901 from the server, while still supporting the basic functions of
12902 trailing-slash redirects and DirectoryIndex files. Note that if
12903 you're carrying over an old Configuration file and you use directory
12904 indexing then you'll want to add:
12906 Module autoindex_module mod_autoindex.o
12908 before mod_dir in your Configuration. [Dean Gaudet]
12910 *) popendir/pclosedir created to properly protect directory scanning.
12911 [Dean Gaudet] PR#525
12913 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
12914 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
12915 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
12918 *) The AccessFileName directive can now take more than one filename.
12919 ["Lou D. Langholtz" <ldl usi.utah.edu>]
12921 *) The new mod_mime_magic can be used to "magically" determine the type
12922 of a file if the extension is unknown. Based on the unix file(1)
12923 command. [Ian Kluft <ikluft cisco.com>]
12925 *) We now determine and display the time spent processing a
12926 request if desired. [Jim Jagielski]
12928 *) mod_status: PID field of "dead" child slots no longer displays
12929 main httpd process's PID. [Jim Jagielski]
12931 *) Makefile.nt added - to build all the bits from the command line:
12932 nmake -f Makefile.nt
12933 Doesn't yet work properly. [Ben Laurie]
12935 *) Default text of 404 error is now "Not Found" rather than the
12936 potentially misleading "File Not Found". [Ken Coar]
12938 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
12939 for the net if we require people that actually need this data to
12940 enable it. [Linus Torvalds]
12942 *) directory_walk() is an expensive function, keep a little more state to
12943 avoid needless string counting. Add two new functions make_dirstr_parent
12944 and make_dirstr_prefix which replace all existing uses of make_dirstr.
12945 The new functions are a little less general than make_dirstr, but
12946 work more efficiently (less memory, less string counting).
12949 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
12950 to LDFLAGS) to avoid complications with lex rules in make files.
12951 [Dean Gaudet] PR#372
12953 *) run_method optimized to avoid needless scanning over NULLs in the
12954 module list. [Dean Gaudet]
12956 *) Revamp of (unix) scoreboard management code such that it avoids
12957 unnecessary traversals of the scoreboard on each hit. This is
12958 particularly important for high volume sites with a large
12959 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
12960 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
12961 httpd.h. [Dean Gaudet]
12963 *) In configurations using multiple Listen statements it was possible for
12964 busy sockets to starve other sockets of service. [Dean Gaudet]
12966 *) Added hook so standalone_main can be replaced at compile time
12967 (define STANDALONE_MAIN)
12970 *) Lowest-level read/write functions in buff.c will be replaced with
12971 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
12972 compile time. The default sfio discipline will behave as apache
12973 would without sfio compiled in.
12976 *) Enhance UserDir directive (mod_userdir) to accept a list of
12977 usernames for the 'disable' keyword, and add 'enable user...' to
12978 selectively *en*able userdirs if they're globally disabled.
12981 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
12982 will work with Netscape dbm files. (dbmmanage will probably not
12983 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
12985 *) Add a ListenBacklog directive to control the backlog parameter
12986 passed to listen(). Also change the default to 511 from 512.
12989 *) API: A new handler response DONE which informs apache that the
12990 request has been handled and it can finish off quickly, similar to
12991 how it handles errors. [Rob Hartill]
12993 *) Turn off chunked encoding after sending terminating chunk/footer
12994 so that we can't do it twice by accident. [Roy Fielding]
12996 *) mod_expire also issues Cache-Control: max-age headers.
12999 *) API: Added kill_only_once option for free_proc_chain so that it won't
13000 aggressively try to kill off specific children. For fastcgi.
13001 [Stanley Gambarin <gambarin OpenMarket.com>]
13003 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
13005 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
13006 When used together, these cause mod_dir to emit HEIGHT and WIDTH
13007 attributes in the FancyIndexing IMG tags. [Ken Coar]
13009 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
13011 *) PORT: Added Windows NT support
13012 [Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
13014 Changes with Apache 1.2.6
13016 *) mod_include when using XBitHack Full would send ETags in addition to
13017 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
13018 [Dean Gaudet] PR#1133
13020 *) SECURITY: When a client connects to a particular port/addr, and
13021 gives a Host: header ensure that the virtual host requested can
13022 actually be reached via that port/addr. [Ed Korthof <ed organic.com>]
13024 *) Support virtual hosts with wildcard port and/or multiple ports
13025 properly. [Ed Korthof <ed organic.com>]
13027 *) Fixed some case-sensitivity issues according to RFC2068.
13030 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
13031 and mod_include.c. [Dean Gaudet]
13033 *) Variable 'cwd' was being used pointlessly before being set.
13036 *) SIGURG doesn't exist on all platforms.
13037 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
13039 *) When an error occurs during a POST, or other operation with a
13040 request body, the body has to be read from the net before allowing
13041 a keepalive session to continue. [Roy Fielding] PR#1399
13043 *) When an error occurs in fcntl() locking suggest the user look up
13044 the docs for LockFile. [Dean Gaudet]
13046 *) table_set() and table_unset() did not deal correctly with
13047 multiple occurrences of the same key. [Stephen Scheck
13048 <sscheck infonex.net>, Ben Laurie] PR#1604
13050 *) send_fd_length() did not calculate total_bytes_sent properly in error
13051 cases. [Ben Reser <breser regnow.com>] PR#1366
13053 *) r->connection->user was allocated in the wrong pool causing corruption
13054 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
13056 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
13057 Also removed the auto-generated link to www.apache.org that was the
13058 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
13060 *) Multiple "close" tokens may have been set in the "Connection"
13061 header, not an error, but a waste.
13062 [<Ronald.Tschalaer psi.ch>] PR#1683
13064 *) "basic" and "digest" auth tokens should be tested case-insensitive.
13065 [<Ronald.Tschalaer psi.ch>] PR#1599, PR#1666
13067 *) It appears the "257th byte" bug (see
13068 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
13069 at the 256th byte as well. Fixed. [Dean Gaudet]
13071 *) mod_rewrite would not handle %3f properly in some situations.
13074 *) Apache could generate improperly chunked HTTP/1.1 responses when
13075 the bputc() or rputc() functions were used by modules (such as
13076 mod_include). [Dean Gaudet]
13078 *) #ifdef wrap a few #defines in httpd.h to make life easier on
13079 some ports. [Ralf Engelschall]
13081 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
13083 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
13085 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
13087 Changes with Apache 1.2.5
13089 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
13090 only an issue on systems without a MAXDNAME define or where
13091 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
13093 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
13096 *) Fix core dump in the ftp proxy when reading incorrectly formatted
13097 directory listings. [Marc Slemko]
13099 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
13102 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
13103 is used to read various types of files such as htaccess and
13104 htpasswd files. [Marc Slemko]
13106 *) SECURITY: Ensure that the buffer returned by ht_time is always
13107 properly null terminated. [Marc Slemko]
13109 *) SECURITY: General mod_include cleanup, including fixing several
13110 possible buffer overflows and a possible infinite loop. This cleanup
13111 was done against 1.3 code and then backported to 1.2, the result
13112 is a large difference (due to indentation cleanup in 1.3 code).
13113 Users interested in seeing a smaller set of relevant differences
13114 should consider comparing against src/modules/standard/mod_include.c
13115 from the 1.3b3 release. Non-indentation changes to mod_include
13116 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
13118 *) SECURITY: Numerous changes to mod_imap in a general cleanup
13119 including fixing a possible buffer overflow. This cleanup also
13120 was done with 1.3 code as a basis, see the previous note
13121 about mod_include. [Dean Gaudet]
13123 *) SECURITY: If a htaccess file can not be read due to bad
13124 permissions, deny access to the directory with a HTTP_FORBIDDEN.
13125 The previous behavior was to ignore the htaccess file if it could not
13126 be read. This change may make some setups with unreadable
13127 htaccess files stop working. PR#817 [Marc Slemko]
13129 *) SECURITY: no2slash() was O(n^2) in the length of the input.
13130 Make it O(n). This inefficiency could be used to mount a denial
13131 of service attack against the Apache server. Thanks to
13132 Michal Zalewski <lcamtuf boss.staszic.waw.pl> for reporting
13133 this. [Dean Gaudet]
13135 *) mod_include used uninitialized data for some uses of && and ||.
13136 [Brian Slesinsky <bslesins wired.com>] PR#1139
13138 *) mod_imap should decline all non-GET methods.
13139 [Jay Bloodworth <jay pathways.sde.state.sc.us>]
13141 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
13143 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
13144 r->filename. Since those two are meant to be in sync with each other
13145 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
13147 *) mod_include did not properly handle all possible redirects from sub-
13148 requests. [Ken Coar]
13150 *) Inetd mode (which is buggy) uses timeouts without having setup the
13151 jmpbuffer. [Dean Gaudet] PR#1064
13153 *) Work around problem under Linux where a child will start looping
13154 reporting a select error over and over.
13155 [Rick Franchuk <rickf transpect.net>] PR#1107
13157 Changes with Apache 1.2.4
13159 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
13160 always making requests with the full-URI instead of just the URI path.
13161 [Marc Slemko, Roy Fielding]
13163 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
13164 on this platform. [Marc Slemko]
13166 Changes with Apache 1.2.3
13168 *) The request to a remote proxy was mangled if it was generated as the
13169 result of a ProxyPass directive. URL schemes other than http:// were not
13170 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
13171 PR#812 [Lars Eilebrecht]
13173 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
13174 information for case where proxy module is not available. [Marc Slemko]
13176 *) Force proxy to always respond as HTTP/1.0, which it was failing to
13177 do for errors and cached responses. [Roy Fielding]
13179 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
13181 Changes with Apache 1.2.2 [not released]
13183 *) Fixed another long-standing bug in sub_req_lookup_file where it would
13184 happily skip past access checks on subdirectories looked up with relative
13185 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
13188 *) Add lockfile name to error message printed out when
13189 USE_FLOCK_SERIALIZED_ACCEPT is defined.
13192 *) Enhanced the chunking and error handling inside the buffer functions.
13193 [Dean Gaudet, Roy Fielding]
13195 *) When merging the main server's <Directory> and <Location> sections into
13196 a vhost, put the main server's first and the vhost's second. Otherwise
13197 the vhost can't override the main server. [Dean Gaudet] PR#717
13199 *) The <Directory> code would merge and re-merge the same section after
13200 a match was found, possibly causing problems with some modules.
13203 *) Fixed an infinite loop in mod_imap for references above the server root.
13204 [Dean Gaudet] PR#748
13206 *) mod_include cleanup showed that handle_else was being used to handle
13207 endif. It didn't cause problems, but it was cleaned up too.
13210 *) Last official synchronization of mod_rewrite with author version (because
13211 mod_rewrite is now directly developed by the author at the Apache Group):
13212 o added diff between mod_rewrite 3.0.6+ and 3.0.9
13213 minus WIN32/NT stuff, but plus copyright removement.
13215 - workaround for detecting infinite rewriting loops
13216 - fixed setting of env vars when "-" is used as subst string
13217 - fixed forced response code on redirects (PR#777)
13218 - fixed cases where r->args is ""
13219 - kludge to disable locking on pipes under braindead SunOS
13220 - fix for rewritelog in cases where remote hostname is unknown
13221 - fixed totally damaged request_rec walk-back loop
13222 o remove static from local data and add static to global ones.
13223 o replaced ugly proxy finding stuff by simple
13224 find_linked_module("mod_proxy") call.
13225 o added missing negation char on rewritelog()
13226 o fixed a few comment typos
13227 [Ralf S. Engelschall]
13229 *) Anonymous_LogEmail was logging on each subrequest.
13230 [Dean Gaudet] PR#421, PR#868
13232 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
13233 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
13234 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
13235 Additionally mod_browser now triggers during translate_name to workaround
13236 a deficiency in the header_parse phase.
13237 [Dean Gaudet] PR#875

13243 *) Properly treat <files> container like other containers in mod_info.
13244 [Marc Slemko] PR#848
13246 *) The proxy didn't treat the "Host:" keyword of the host header as case-
13247 insensitive. The proxy would corrupt the first line of a response from
13248 an HTTP/0.9 server. [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#813,814
13250 *) mod_include would log some bogus values occasionally.
13251 [Skip Montanaro <skip calendar.com>, Marc Slemko] PR#797
13253 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
13254 under Solaris 2.x (up through 2.5.1). It has been fixed.
13255 [Dean Gaudet] PR#832
13257 *) API: In HTTP/1.1, whether or not a request message contains a body
13258 is independent of the request method and based solely on the presence
13259 of a Content-Length or Transfer-Encoding. Therefore, our default
13260 handlers need to be prepared to read a body even if they don't know
13261 what to do with it; otherwise, the body would be mistaken for the
13262 next request on a persistent connection. discard_request_body()
13263 has been added to take care of that. [Roy Fielding] PR#378
13265 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
13266 release version number, such that it always increases along the
13267 same lines as our source code branching. [Roy Fielding]
13269 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
13271 Changes with Apache 1.2.1
13273 *) SECURITY: Don't serve file system objects unless they are plain files,
13274 symlinks, or directories. This prevents local users from using pipes
13275 or named sockets to invoke programs for an extremely crude form of
13278 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
13279 could contain "../" allowing a local user to "publish" any file on
13280 the system. No slashes are allowed now. [Dean Gaudet]
13282 *) SECURITY: It was possible to violate the symlink Options using mod_dir
13283 (headers, readmes, titles), mod_negotiation (type maps), or
13284 mod_cern_meta (meta files). [Dean Gaudet]
13286 *) SECURITY: Apache will refuse to run as "User root" unless
13287 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
13289 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
13290 if it contained a .htaccess disallowing symlinks. This is contrary
13291 to the rule that symlink permissions are tested with the symlink
13292 options of the parent directory. [Dean Gaudet] PR#353
13294 *) CONFIG: The LockFile directive can be used to place the serializing
13295 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
13296 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
13299 *) Request processing now retains state of whether or not the request
13300 body has been read, so that internal redirects and subrequests will
13301 not try to read it twice (and block). [Roy Fielding]
13303 *) Add a placeholder in modules/Makefile to avoid errors with certain
13304 makes. [Marc Slemko]
13306 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

13312 *) Attempt to work around problems with third party libraries that do not
13313 handle high numbered descriptors (examples include bind, and
13314 solaris libc). On all systems apache attempts to keep all permanent
13315 descriptors above 15 (called the low slack line). Solaris users
13316 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
13317 which keeps all non-FILE * descriptors above 255. On all systems
13318 this should make supporting large numbers of vhosts with many open
13319 log files more feasible. If this causes trouble please report it,
13320 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
13321 [Dean Gaudet] various PRs
13323 *) Related to the last entry, network sockets are now opened before
13324 log files are opened. The only known case where this can cause
13325 problems is under Solaris with many virtualhosts and many Listen
13326 directives. But using -DHIGH_SLACK_LINE=256 described above will
13327 work around this problem. [Dean Gaudet]

13378 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
13379 [Doug MacEachern, Rob Hartill]
13381 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
13382 reading from one buffer and writing to another, at least until it has
13383 a custom timeout handler. [Roy Fielding and Petr Lampa]
13385 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
13386 apparently due to a mismatch between sigaction and setjmp.
13387 [Roy Fielding] PR#502
13389 *) Log correct status code if we timeout before receiving a request (408)
13390 or if we received a request-line that was too long to process (414).
13391 [Ed Korthof and Roy Fielding] PR#601
13393 *) Virtual hosts with the same ServerName, but on different ports, were
13394 not being selected properly. [Ed Korthof]
13396 *) Added code to return the requested IP address from proxy_host2addr()
13397 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
13398 change submitted by Jozsef Hollosi <hollosi sbcm.com>.
13399 [Chuck Murcko] PR#614
13401 *) If multiple requests on a single connection are used to retrieve
13402 data from different virtual hosts, the virtual host list would be
13403 scanned starting with the most recently used VH instead of the first,
13404 causing most virtual hosts to be ignored.
13405 [Paul Sutton and Martin Mares] PR#610
13407 *) The OS/2 handling of process group was broken by a porting patch for
13408 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
13410 *) Inherit virtual server port from main server if none (or "*") is
13411 given for VirtualHost. [Dean Gaudet] PR#576
13413 *) If the lookup for a DirectoryIndex name with content negotiation
13414 has found matching variants, but none are acceptable, return the
13415 negotiation result if there are no more DirectoryIndex names to lookup.
13416 [Petr Lampa and Roy Fielding]
13418 *) If a soft_timeout occurs after keepalive is set, then the main child
13419 loop would try to read another request even though the connection
13420 has been aborted. [Roy Fielding]
13422 *) Configure changes: Allow for whitespace at the start of a
13423 Module declaration. Also, be more understanding about the
13424 CC=/OPTIM= format in Configuration. Finally, fix compiler
13425 flags if using HP-UX's cc compiler. [Jim Jagielski]
13427 *) Subrequests and internal redirects now inherit the_request from the
13428 original request-line. [Roy Fielding]
13430 *) Test for error conditions before creating output header fields, since
13431 we don't want the error message to include those fields. Likewise,
13432 reset the content_language(s) and content_encoding of the response
13433 before generating or redirecting to an error message, since the new
13434 message will have its own Content-* definitions. [Dean Gaudet]
13436 *) Restored the semantics of headers_out (headers sent only with 200..299
13437 and 304 responses) and err_headers_out (headers sent with all responses).
13438 Avoid the overhead of copying tables if err_headers_out is empty
13439 (the usual case). [Roy Fielding]
13441 *) Fixed a couple places where a check for the default Content-Type was
13442 not properly checking both the value configured by the DefaultType
13443 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
13444 of DEFAULT_TYPE to match the documented default (text/plain).
13445 [Dean Gaudet] PR#506
13447 *) Escape the HTML-sensitive characters in the Request-URI that is
13448 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
13450 *) Properly initialize the flock structures used by the mutex locking
13451 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
13454 *) The method for determining PATH_INFO has been restored to the pre-1.2b
13455 (and NCSA httpd) definition wherein it was the extra path info beyond
13456 the CGI script filename. The environment variable FILEPATH_INFO has
13457 been removed, and instead we supply the original REQUEST_URI to any
13458 script that wants to be Apache-specific and needs the real URI path.
13459 This solves a problem with existing scripts that use extra path info
13460 in the ScriptAlias directive to pass options to the CGI script.
13463 *) The _default_ change in 1.2b10 will change the behaviour on configs
13464 that use multiple Listen statements for listening on multiple ports.
13465 But that change is necessary to make _default_ consistent with other
13466 forms of <VirtualHost>. It requires such configs to be modified
13467 to use <VirtualHost _default_:*>. The documentation has been
13468 updated. [Dean Gaudet] PR#530
13470 *) If an ErrorDocument CGI script is used to respond to an error
13471 generated by another CGI script which has already read the message
13472 body of the request, the server would block trying to read the
13473 message body again. [Rob Hartill]
13475 *) signal() replacement conflicted with a define on QNX (and potentially
13476 other platforms). Fixed. [Ben Laurie] PR#512
13478 Changes with Apache 1.2b10
13480 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
13481 to be configured via -D in Configuration. [Dean Gaudet] PR#449
13483 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
13485 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
13487 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
13488 config, in case the hostent struct returned is trash.
13489 [Chuck Murcko] PR #491
13491 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
13492 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
13494 Changes with Apache 1.2b9 [never announced]
13496 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
13497 changes and in anticipation of 1.2 final release. [Roy Fielding]
13499 *) Fix problem with scripts not receiving a SIGPIPE when client drops
13500 the connection (e.g., when user presses Stop). Apache will now stop
13501 trying to send a message body immediately after an error from write.
13502 [Roy Fielding and Nathan Kurz] PR#335
13504 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
13505 than mod_alias, and mod_alias has higher priority than mod_proxy;
13506 rearranged other modules to enhance understanding of their purpose
13507 and relative order (and maybe even reduce some overhead).
13508 [Roy Fielding and Sameer Parekh]
13510 *) Fix graceful restart. Eliminate many signal-related race
13511 conditions in both forms of restart, and in SIGTERM. See
13512 htdocs/manual/stopping.html for details on stopping and
13513 restarting the parent. [Dean Gaudet]
13515 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
13516 memory allocator to avoid a behaviour that required extra blocks to
13517 be allocated. [Dean Gaudet]
13519 *) Allow suexec to access files relative to current directory but not
13520 above. (Excluding leading / or any .. directory.) [Ken Coar]
13523 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
13524 PR#367, 368, 354, 453
13526 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
13527 while obtaining the /~user and save the username in a separate data
13528 area so that it won't be overwritten by the call to getgrgid(), and
13529 fix some misuse of the pool string allocation functions. Also fixes
13530 a general problem with parsing URL query info into args for CGI scripts.
13531 [Roy Fielding] PR#339, 367, 354, 453
13533 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
13535 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
13537 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
13538 AuthDBAuthoritative. [Marc Slemko] PR#420
13540 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
13542 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
13543 object that can't be PUT, or FOOBAR for some method FOOBAR that
13544 apache doesn't know about at all). Log 404s that occur in mod_include.
13545 [Paul Sutton, John Van Essen]
13547 *) If a soft timeout (or lingerout) occurs while trying to flush a
13548 buffer or write inside buff.c or fread'ing from a CGI's output,
13549 then the timeout would be ignored. [Roy Fielding] PR#373
13551 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
13552 parsing of headers. If the terminating empty-line CRLF occurs starting
13553 at the 256th or 257th byte of output, then Navigator will think a normal
13554 image is invalid. We are guessing that this is because their initial
13555 read of a new request uses a 256 byte buffer. We check the bytes written
13556 so far and, if we are about to tickle the bug, we instead insert a
13557 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
13559 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
13560 of an external redirection. [Roy Fielding and Paul Sutton]
13562 *) Configure would create a broken Makefile if the configuration file
13563 contained a commented-out Rule. [Roy Fielding]
13565 *) Promote per_dir_config and subprocess_env from the subrequest to the
13566 main request in mod_negotiation. In particular this fixes a bug
13567 where <Files> sections wouldn't properly apply to negotiated content.
13570 *) Fix a potential deadlock in mod_cgi script_err handling.
13571 [Ralf S. Engelschall]
13573 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
13574 [Mitchell Blank Jr]
13576 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
13577 .htaccess files because the RewriteBase was not replaced correctly.
13578 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
13579 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
13581 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
13582 1.x the settings are those of pre-1.2b8. For 2.x we include
13583 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
13584 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
13585 [Dean Gaudet] PR#336, PR#340
13587 *) Redirect did not preserve ?query_strings when present in the client's
13588 request. [Dean Gaudet]
13590 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
13592 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
13594 *) Add UnixWare compile/install instructions. [Chuck Murcko]
13596 *) Add mod_example (illustration of API techniques). [Ken Coar]
13598 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
13600 *) Improve handling of directories when filenames have spaces in them.
13603 *) For hosts with multiple IP addresses, try all additional addresses if
13604 necessary to get a connect. Fail only if hostent address list is
13605 exhausted. [Chuck Murcko]
13607 *) More signed/unsigned port fixes. [Dean Gaudet]
13609 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
13612 Changes with Apache 1.2b8
13614 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
13615 to it. [Marc Slemko]
13617 *) The addition of <Location> and <File> directives made the
13618 sub_req_lookup_simple() function bogus, so we now handle
13619 the special cases directly. [Dean Gaudet]
13621 *) We now try to log where the server is dumping core when a fatal
13622 signal is received. [Ken Coar]
13624 *) Improved lingering_close by adding a special timeout, removing the
13625 spurious log messages, removing the nonblocking settings (they
13626 are not needed with the better timeout), and adding commentary
13627 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
13628 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
13630 *) Send error messages about setsockopt failures to the server error
13631 log instead of stderr. [Roy Fielding]
13633 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
13635 *) Stopgap solution for CGI 3-second delay with server-side includes: if
13636 processing a subrequest, allocate memory from r->main->pool instead
13637 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
13638 in the middle of an SSI request. [Dean Gaudet] PR #122
13640 *) Fixed status of response when POST is received for a nonexistent URL
13641 (was sending 405, now 404) and when any method is sent with a
13642 full-URI that doesn't match the server and the server is not acting
13643 as a proxy (was sending 501, now 403). [Roy Fielding]
13645 *) Host port changed to unsigned short. [Ken Coar] PR #276
13647 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
13649 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
13651 *) Report extra info from errno with many errors that cause httpd to exit.
13652 spawn_child, popenf, and pclosef now have valid errno returns in the
13653 event of an error. Correct problems where errno was stomped on
13654 before being reported. [Dean Gaudet]
13656 *) In the proxy, if the cache filesystem was full, garbage_coll() was
13657 never called, and thus the filesystem would remain full indefinitely.
13658 We now also remove incomplete cache files left if the origin server
13659 didn't send a Content-Length header and either the client has aborted
13660 transfer or bwrite() to client has failed. [Petr Lampa]
13662 *) Fixed the handling of module and script-added header fields.
13663 Improved the interface for sending header fields and reduced
13664 the duplication of code between sending okay responses and errors.
13665 We now always send both headers_out and err_headers_out, and
13666 ensure that the server-reserved fields are not being overridden,
13667 while not overriding those that are not reserved. [Roy Fielding]
13669 *) Moved transparent content negotiation fields to err_headers_out
13670 to reflect above changes. [Petr Lampa]
13672 *) Fixed the determination of whether or not we should make the
13673 connection persistent for all of the cases where some other part
13674 of the server has already indicated that we should not. Also
13675 improved the ordering of the test so that chunked encoding will
13676 be set whenever it is desired instead of only when KeepAlive
13677 is enabled. Added persistent connection capability for most error
13678 responses (those that do not indicate a bad input stream) when
13679 accessed by an HTTP/1.1 client. [Roy Fielding]
13681 *) Added missing timeouts for sending header fields, error responses,
13682 and the last chunk of chunked encoding, each of which could have
13683 resulted in a process being stuck in write forever. Using soft_timeout
13684 requires that the sender check for an aborted connection rather than
13685 continuing after an EINTR. Timeouts that used to be initiated before
13686 send_http_header (and never killed) are now initiated only within or
13687 around the routines that actually do the sending, and not allowed to
13688 propagate above the caller. [Roy Fielding]
13690 *) mod_auth_anon required an @ or a . in the email address, not both.
13693 *) per_dir_defaults weren't set correctly until directory_walk for
13694 name-based vhosts. This fixes an obscure bug with the wrong config
13695 info being used for vhosts that share the same ip as the server.
13698 *) Improved generation of modules/Makefile to be more generic for
13699 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
13701 *) Generate makefile dependency for Configuration based on the actual
13702 name given when running the Configure process. [Dean Gaudet]
13704 *) Fixed problem with vhost error log not being set prior to
13705 initializing virtual hosts. [Dean Gaudet]
13707 *) Fixed infinite loop when a trailing slash is included after a type map
13708 file URL (extra path info). [Petr Lampa]
13710 *) Fixed server status updating of per-connection counters. [Roy Fielding]
13712 *) Add documentation for DNS issues (reliability and security), and try
13713 to explain the virtual host matching process. [Dean Gaudet]
13715 *) Try to continue gracefully by disabling the vhost if a DNS lookup
13716 fails while parsing the configuration file. [Dean Gaudet]
13718 *) Improved calls to setsockopt. [Roy Fielding]
13720 *) Negotiation changes: Don't output empty content-type in variant list;
13721 Output charset in variant list; Return sooner from handle_multi() if
13722 no variants found; Add handling of '*' wildcard in Accept-Charset.
13723 [Petr Lampa and Paul Sutton]
13725 *) Fixed overlaying of request/sub-request notes and headers in
13726 mod_negotiation. [Dean Gaudet]
13728 *) If two variants' charset quality are equal and one is the default
13729 charset (iso-8859-1), then prefer the variant that was specifically
13730 listed in Accept-Charset instead of the default. [Petr Lampa]
13732 *) Memory allocation problem in push_array() -- it would corrupt memory
13733 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
13735 *) invoke_handler() doesn't handle mime arguments in content-type
13736 [Petr Lampa] PR#160
13738 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
13741 *) Fixed problem with ErrorDocument not working for virtual hosts
13742 due to one of the performance changes in 1.2b7. [Dean Gaudet]
13744 *) Log an error message if we get a request header that is too long,
13745 since it may indicate a buffer overflow attack. [Marc Slemko]
13747 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
13748 not reject URLs without a double-slash, as per RFC2068 section 3.2.
13749 [Ken Coar] PR #146, #187
13751 *) Added table entry placeholder for new header_parser callback
13752 in all of the distributed modules. [Ken Coar] PR #191
13754 *) Allow for cgi files without the .EXE extension on them under OS/2.
13755 [Garey Smiley] PR #59
13757 *) Fixed error message when resource is not found and URL contains
13758 path info. [Petr Lampa and Dean Gaudet] PR #40
13760 *) Fixed user and server confusion over what should be a virtual host
13761 and what is the main server, resulting in access to something
13762 other than the name defined in the virtualhost directive (but
13763 with the same IP address) failing. [Dean Gaudet]
13765 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
13766 AIX; improves the redirection stuff to enable the users to generally
13767 redirect to http, https, gopher and ftp; added TIME variable for
13768 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
13769 special patterns >STRING, <STRING and =STRING to RewriteCond, which
13770 can be used in conjunction with %{TIME} or other variables to create
13771 time-dependent rewriting rules. [Ralf S. Engelschall]
13773 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
13774 Module authors may need to adjust their code for proper cleanup to take
13775 place (that is, call note_cleanups_for_fd()). This change fixes problems
13776 with file descriptors being erroneously closed when the proxy module was
13777 in use. [Ben Laurie]
13779 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
13780 initgroups() to hose the group information needed for later
13781 comparisons. [Randy Terbush]
13783 *) Remove unnecessary call to va_end() in create_argv() which
13784 caused a SEGV on some systems.
13786 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
13789 *) Clear memory allocated for listeners. [Randy Terbush]
13791 *) Improved handling of IP address as a virtualhost address and
13792 introduced "_default_" as a synonym for the default vhost config.
13793 [Dean Gaudet] PR #212
13795 Changes with Apache 1.2b7
13797 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
13799 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
13801 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
13802 - replace protocol response numbers with symbols
13803 - save variant-list into main request notes
13804 - free allocated memory from subrequests
13805 - merge notes, headers_out and err_headers_out
13807 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
13808 "HTTP/#.# ###*" to be more lenient about what we accept.
13811 *) more proxy FTP bug fixes:
13812 - Changed send_dir() to remove user/passwd from displayed URL.
13813 - Changed login error messages to be more descriptive.
13814 - remove setting of SO_DEBUG socket option
13815 - Make ftp_getrc() more lenient about multiline responses,
13816 specifically, 230 responses which don't have continuation 230-
13817 on each line). These seem to be all NT FTP servers, and while
13818 perhaps questionable, they appear to be legal by RFC 959.
13819 - Add missing kill_timeout() after transfer to user completes.
13822 *) Fixed problem where a busy server could hang when restarting
13823 after being sent a SIGHUP due to child processes not exiting.
13826 *) Modify mod_include escaping so a '\' only signifies an escaped
13827 character if the next character is one that needs
13828 escaping. [Ben Laurie]
13830 *) Eliminated possible infinite loop in mod_imap when relative URLs are
13831 used with a 'base' directive that does not have a '/' in it.
13832 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
13834 *) Reduced the default timeout from 1200 seconds to 300, and the
13835 one in the sample configfile from 400 to 300. [Marc Slemko]
13837 *) Stop vbprintf from crashing if given a NULL string pointer;
13838 print (null) instead. [Ken Coar]
13840 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
13841 [Marc Slemko and Roy Fielding]
13843 *) Fixed problem with mod_cgi-generated internal redirects trying to
13844 read the request message-body twice. [Archie Cobbs and Roy Fielding]
13846 *) Reduced timeout on lingering close, removed possibility of a blocked
13847 read causing the child to hang, and stopped logging of errors if
13848 the socket is not connected (reset by client). [Roy Fielding]
13850 *) Rearranged main child loop to remove duplication of code in
13851 select/accept and keep-alive requests, fixed several bugs regarding
13852 checking scoreboard_image for exit indication and failure to
13853 account for all success conditions and trap all error conditions,
13854 prevented multiple flushes before closing the socket; close the entire
13855 socket buffer instead of just one descriptor, prevent logging of
13856 EPROTO and ECONNABORTED on platforms where supported, and generally
13857 improved readability. [Roy Fielding]
13859 *) Extensive performance improvements. Cleaned up inefficient use of
13860 auto initializers, multiple is_matchexp calls on a static string,
13861 and excessive merging of response_code_strings. [Dean Gaudet]
13863 *) Added double-buffering to mod_include to improve performance on
13864 server-side includes. [Marc Slemko]
13866 *) Several fixes for suexec wrapper. [Randy Terbush]
13867 - Make wrapper work for files on NFS filesystem.
13868 - Fix portability problem of MAXPATHLEN.
13869 - Fix array overrun problem in clean_env().
13870 - Fix allocation of PATH environment variable
13872 *) Removed extraneous blank line is description of mod_status chars.
13875 *) Logging of errors from the call_exec routine simply went nowhere,
13876 since the logfile fd has been closed, so now we send them to stderr.
13877 [Harald T. Alvestrand]
13879 *) Fixed core dump when DocumentRoot is a CGI.
13880 [Ben Laurie, reported by <geddis tesserae.com>]
13882 *) Fixed potential file descriptor leak in mod_asis; updated it and
13883 http_core to use pfopen/pfclose instead of fopen/fclose.
13884 [Randy Terbush and Roy Fielding]
13886 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
13887 as the DEC Alpha which is 64-bit but uses 32-bit ints.
13888 [Dean Gaudet and Ken Coar]
13890 *) Return a 302 response code to the client when sending a redirect
13891 due to a missing trailing '/' on a directory instead of a 301; now
13892 it is cacheable. [Markus Gyger]
13894 *) Fix condition where, if a bad directive occurs in .htaccess, and
13895 sub_request() goes first to this directory, then log_reason() will
13896 SIGSEGV because it doesn't have initialized r->per_dir_config.
13897 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
13899 *) Fix handling of lang_index in is_variant_better(). This was
13900 causing problems which resulted in the server sending the
13901 wrong language document in some cases. [Petr Lampa]
13903 *) Remove free() from clean_env() in suexec wrapper. This was nuking
13904 the clean environment on some systems.
13906 *) Tweak byteserving code (e.g. serving PDF files) to work around
13907 bugs in Netscape Navigator and Microsoft Internet Explorer.
13908 Emit Content-Length header when sending multipart/byteranges.
13911 *) Port to HI-UX/WE2. [Nick Maclaren]
13913 *) Port to HP MPE operating system for HP 3000 machines
13914 [Mark Bixby <markb cccd.edu>]
13916 *) Fixed bug which caused a segmentation fault if only one argument
13917 given to RLimit* directives. [Ed Korthof]
13919 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
13921 *) Improved buffered output to the client by delaying the flush decision
13922 until the BUFF code is actually about to read the next request.
13923 This fixes a problem introduced in 1.2b5 with clients that send
13924 an extra CRLF after a POST request. Also improved chunked output
13925 performance by combining writes using writev() and removing as
13926 many bflush() calls as possible. NOTE: Platforms without writev()
13927 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
13928 or Configure, unless we have already done so. [Dean Gaudet]
13930 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
13932 *) Fixed mod_info output corruption bug introduced by buffer overflow
13933 fixes. [Dean Gaudet]
13935 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
13936 for the special case of a 304 response. [Paul Sutton]
13938 *) Improved handling of TRACE method by bypassing normal method handling
13939 and header parsing routines; fixed Allow response to always allow TRACE.
13942 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
13944 *) Cleaned-up some of the generated HTML. [Ken Coar]
13946 Changes with Apache 1.2b6
13948 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
13950 *) Fix typo introduced in fix for potential infinite loop around
13951 accept() in child_main(). This change caused the rev to 1.2b6.
13952 1.2b5 was never a public beta.
13954 Changes with Apache 1.2b5
13956 *) Change KeepAlive semantics (On|Off instead of a number), add
13957 MaxKeepAliveRequests directive. [Alexei Kosut]
13959 *) Various NeXT compilation patches, as well as a change in
13960 regex/regcomp.c since that file also used a NEXT define.
13963 *) Allow * to terminate the end of a directory match in mod_dir.
13964 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
13966 *) Don't call can_exec() if suexec_enabled. Calling this requires
13967 scripts executed by the suexec wrapper to be world executable, which
13968 defeats one of the advantages of running the wrapper. [Randy Terbush]
13970 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
13973 *) Migration from sprintf() to snprintf() to avoid buffer
13974 overflows. [Marc Slemko]
13976 *) Provide portable snprintf() implementation (ap_snprintf)
13977 as well as *cvt family. [Jim Jagielski]
13979 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
13982 *) Remove mod_fastcgi.c from the distribution. This module appears
13983 to be maintained more through the Open Market channels and should
13984 continue to be easily available at http://www.fastcgi.com/
13986 *) Fixed bug in modules/Makefile that wouldn't allow building in more
13987 than one subdirectory (or cleaning, either). [Jeremy Laidman]
13989 *) mod_info assumed that the config files were relative to ServerRoot.
13992 *) CGI scripts called as an error document resulting from failed
13993 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
13995 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
13998 *) Properly check errno to prevent display of a directory index
13999 when server receives a long enough URL to confuse stat().
14002 *) Several security enhancements to suexec wrapper. It is _highly_
14003 recommended that previously installed versions of the wrapper
14004 be replaced with this version. [Randy Terbush, Jason Dour]
14006 - ~user execution now properly restricted to ~user's home
14007 directory and below.
14008 - execution restricted to UID/GID > 100
14009 - restrict passed environment to known variables
14010 - call setgid() before initgroups() (portability fix)
14011 - remove use of setenv() (portability fix)
14013 *) Add HTTP/1.0 response forcing. [Ben Laurie]
14015 *) Add access control via environment variables. [Ben Laurie]
14017 *) Add rflush() function. [Alexei Kosut]
14019 *) remove duplicate pcalloc() call in new_connection().
14021 *) Fix incorrect comparison which could allow number of children =
14022 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
14023 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
14025 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
14026 AIX PS/2, CONVEXOS. [Jim Jagielski]
14028 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
14029 It's more portable. [Martin Kraemer]
14031 *) Replace references to make in Makefile.tmpl with $(MAKE).
14034 *) Add ProxyBlock directive w/IP address caching. Add IP address
14035 caching to NoCache directive as well. ProxyBlock works with all
14036 handlers; NoCache now also works with FTP for anonymous logins.
14037 Still more code cleanup. [Chuck Murcko]
14039 *) Add "header parse" API hook [Ben Laurie]
14041 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
14043 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
14045 *) Correctly allow access and auth directives in <Files> sections in
14046 server config files. [Alexei Kosut]
14048 *) Fix bug with ServerPath that could cause certain files to be not
14049 found by the server. [Alexei Kosut]
14051 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
14052 double-quote from text and so that it properly checks for unsupported
14053 status codes using the new index_of_response interface. [Roy Fielding]
14055 *) Multiple fixes to the lingering_close code in order to avoid being
14056 interrupted by a stray timeout, to avoid lingering on a connection
14057 that has already been aborted or never really existed, to ensure that
14058 we stop lingering as soon as any error condition is received, and to
14059 prevent being stuck indefinitely if the read blocks. Also improves
14060 reporting of error conditions. [Marc Slemko and Roy Fielding]
14062 *) Fixed initialization of parameter structure for sigaction.
14063 [<mgyger itr.ch>, Adrian Filipi-Martin]
14065 *) Fixed reinitializing the parameters before each call to accept and
14066 select, and removed potential for infinite loop in accept.
14067 [Roy Fielding, after useful PR from <adrian virginia.edu>]
14069 *) Fixed condition where, if a child fails to fork, the scoreboard would
14070 continue to say SERVER_STARTING forever. Eventually, the main process
14071 would refuse to start new children because count_idle_servers() will
14072 count those SERVER_STARTING entries and will always report that there
14073 are enough idle servers. [Phillip Vandry]
14075 *) Fixed bug in bcwrite regarding failure to account for partial writes.
14076 Avoided calling bflush() when the client is pipelining requests.
14077 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
14079 *) Added description of "." mode in server-status [Jim Jagielski]
14081 Changes with Apache 1.2b4
14083 *) Fix possible race condition in accept_mutex_init() that
14084 could leave a small security hole open allowing files to be
14085 overwritten in cases where the server UID has write permissions.
14088 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
14090 *) Fix portablity problem in util_script where ARG_MAX may not be
14091 defined for some systems.
14093 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
14096 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
14097 style magic #! token for better script portability. [Garey Smiley]
14099 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
14100 execution for ~userdir CGI. [Jason Dour]
14102 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
14104 *) Fix month off by one in suexec wrapper logging.
14106 Changes with Apache 1.2b3:
14108 *) Fix error in mod_cgi which could cause resources not to be properly
14109 freed, or worse. [Dean Gaudet]
14111 *) Fix find_string() NULL pointer dereference. [Howard Fear]
14113 *) Add set_flag_slot() at the request of Dirk and others.
14116 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
14118 *) Add changes to improve the error message given for invalid
14119 ServerName parameters. [Dirk vanGulik]
14121 *) Add "Authoritative" directive for Auth modules that don't
14122 currently have it. This gives admin control to assign authoritative
14123 control to an authentication scheme and allow "fall through" for
14124 those authentication modules that aren't "Authoritative" thereby
14125 allowing multiple authentication mechanisms to be chained.
14128 *) Remove requirement for ResourceConfig/AccessConfig if not using
14129 the three config file layout. [Randy Terbush]
14131 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
14133 *) Changes to suexec wrapper to fix the following problems:
14134 1. symlinked homedirs will kill ~userdirs.
14135 2. initgroups() on Linux 2.0.x clobbers gr->grid.
14136 3. CGI command lines paramters problems
14137 4. pw-pwdir for "docroot check" still the httpd user's pw record.
14138 [Randy Terbush, Jason Dour]
14140 *) Change create_argv() to accept variable arguments. This fixes
14141 a problem where arguments were not getting passed to the CGI via
14142 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
14144 *) Collapse multiple slashes in path URLs to properly apply
14145 handlers defined by <Location>. [Alexei Kosut]
14147 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
14149 *) Improve the accuracy of request duration timings by setting
14150 r->request_time in read_request_line() instead of read_request().
14153 *) Reset timeout while reading via get_client_block() in mod_cgi.c
14154 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
14156 *) Add the ability to pass different Makefile.tmpl files to Configure
14157 using the -make flag. [Rob Hartill]
14159 *) Fix coredump triggered when sending a SIGHUP to the server caused
14160 by an assertion failure, in turn caused by an uninitialised field in a
14164 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
14165 PATH_INFO from previous versions of Apache (in certain situations,
14166 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
14167 [later removed in 1.2b11]
14169 *) Add rwrite() function to API to allow for sending strings of
14170 arbitrary length. [Doug MacEachern]
14172 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
14174 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
14175 NeXT. [Jim Jagielski]
14177 *) Removed recent modification to promote the status code on internal
14178 redirects, since the correct fix was to change the default log format
14179 in mod_log_config so that it outputs the original status. [Rob Hartill]
14181 Changes with Apache 1.2b2:
14183 *) Update set_signals() to use sigaction() for setting handlers.
14184 This appears to fix a re-entrant problem in the seg_fault()
14185 bus_error() handlers. [Randy Terbush]
14187 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
14189 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
14191 *) proxy_http.c bugfixes: [Chuck Murcko]
14192 1) fixes possible NULL pointer reference w/NoCache
14193 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
14194 host would cache nothing if it was in the local domain,
14195 and the local domain was in the NoCache list)
14196 3) Adds Host: header when not available
14197 4) Some code cleanup and clarification
14199 *) mod_include.c bugfixes:
14200 1) Fixed an ommission that caused include variables to not
14201 be parsed in config errmsg directives [Howard Fear]
14202 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
14203 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
14204 4) Allow backslash-escaping to all quoted text
14205 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
14206 5) Pass variable to command line if not set in XSSI's env
14209 *) Fix infinite loop when processing Content-language lines in
14210 type-map files. [Alexei Kosut]
14212 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
14214 *) Fixed problem in set_[user|group] that prevented CGI execution
14215 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
14217 *) Added PORTING information file. [Jim Jagielski]
14219 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
14221 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
14223 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
14224 USE_FCNTL_SERIALIZED_ACCEPT was intended.
14226 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
14227 which caused problems of systems where socket s_addr is >32bits.
14229 *) Added comment to explain (r->chunked = 1) side-effect in
14230 http_protocol.c [Roy Fielding]
14232 *) Replaced use of index() in mod_expires.c with more appropriate
14233 and portable isdigit() test. [Ben Laurie]
14235 *) Updated Configure for ...
14236 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
14237 *-dg-dgux* (bad pattern match)
14238 QNX (DEF_WANTHSREGEX=yes)
14239 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
14241 *-unixware211 (new)
14242 and added some user diagnostic info. [Ben Laurie]
14244 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
14245 for better portability. [Jim Jagielski]
14247 *) Updated helpers/GuessOS for ...
14248 SCO 5 (recognize minor releases)
14249 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
14250 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
14251 IRIX64 (-sgi-irix64)
14252 ULTRIX (-unknown-ultrix)
14253 SINIX (-whatever-sysv4)
14254 NCR Unix (-ncr-sysv4)
14255 and fixed something in helpers/PrintPath [Ben Laurie]
14257 Changes with Apache 1.2b1
14259 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
14261 Changes with Apache 1.1.1
14263 *) Fixed bug where Cookie module would make two entries in the
14264 logfile for each access [Mark Cox]
14266 *) Fixed bug where Redirect in .htaccess files would cause memory
14267 leak. [Nathan Neulinger]
14269 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
14271 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
14273 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
14275 Changes with Apache 1.1.0
14277 *) Bring NeXT support up to date. [Takaaki Matsumoto]
14279 *) Bring QNX support up to date. [Ben Laurie]
14281 *) Make virtual hosts default to main server keepalive parameters.
14282 [Alexei Kosut, Ben Laurie]
14284 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
14286 *) Fix missing address family for connect, also remove unreachable statement
14287 in mod_proxy. [Ben Laurie]
14289 *) mod_env now turned on by default in Configuration.tmpl.
14291 *) Bugs which were fixed:
14292 a) yet more mod_proxy bugs [Ben Laurie]
14293 b) CGI works again with inetd [Alexei Kosut]
14294 c) Leading colons were stripped from passwords [<osm interguide.com>]
14295 d) Another fix to multi-method Limit problem [<jk tools.de>]
14297 Changes with Apache 1.1b4
14299 *) r->bytes_sent variable restored. [Robert Thau]
14301 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
14303 *) More possibly unsecure programs removed from the support directory.
14305 *) More mod_auth_msql authentication improvements.
14307 *) VirtualHosts based on Host: headers no longer conflict with the
14310 *) OS/2 compatibility enhancements. [Gary Smiley]
14312 *) POST now allowed to directory index CGI scripts.
14314 *) Actions now work with files of the default type.
14316 *) Bugs which were fixed:
14317 a) more mod_proxy bugs
14318 b) early termination of inetd requests
14319 c) compile warnings on several systems
14320 d) problems when scripts stop reading output early
14322 Changes with Apache 1.1b3
14324 *) Much of cgi-bin and all of cgi-src has been removed, due to
14325 various security holes found and that we could no longer support
14328 *) The "Set-Cookie" header is now special-cased to not merge multiple
14329 instances, since certain popular browsers can not handle multiple
14330 Set-Cookie instructions in a single header. [Paul Sutton]
14332 *) rprintf() added to buffer code, occurrences of sprintf removed.
14335 *) CONNECT method for proxy module, which means tunneling SSL should work.
14336 (No crypto needed) Also a NoCache config directive.
14338 *) Several API additions: pstrndup(), table_unset() and get_token()
14339 functions now available to modules.
14341 *) mod_imap fixups, in particular Location: headers are now complete
14344 *) New "info" module which reports on installed module set through a
14345 special URL, a la mod_status.
14347 *) "ServerPath" directive added - allows for graceful transition
14348 for Host:-header-based virtual hosts.
14350 *) Anonymous authentication module improvements.
14352 *) MSQL authentication module improvements.
14354 *) Status module design improved - output now table-based. [Ben Laurie]
14356 *) htdigest utility included for use with digest authentication
14359 *) mod_negotiation: Accept values with wildcards to be treated with
14360 less priority than those without wildcards at the same quality
14361 value. [Alexei Kosut]
14363 *) Bugs which were fixed:
14364 a) numerous mod_proxy bugs
14365 b) CGI early-termination bug [Ben Laurie]
14366 c) Keepalives not working with virtual hosts
14367 d) RefererIgnore problems
14368 e) closing fd's twice in mod_include (causing core dumps on
14369 Linux and elsewhere).
14371 Changes with Apache 1.1b2
14374 a) core dumps in mod_digest
14375 b) truncated hostnames/ip address in the logs
14376 c) relative URL's in mod_imap map files
14378 Changes with Apache 1.1b1
14380 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
14382 Changes with Apache 1.0.3
14384 *) Internal redirects which occur in mod_dir.c now preserve the
14385 query portion of a request (the bit after the question mark).
14388 *) Escape active characters '<', '>' and '&' in html output in
14389 directory listings, error messages and redirection links.
14392 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
14394 *) Fix for POSIX compliance in waiting for processes in alloc.c.
14397 *) setsockopt no longer takes a const declared argument [Martijn Koster]
14399 *) Reset timeout timer after each successful fwrite() to the network.
14400 This patch adds a reset_timeout() procedure that is called by
14401 send_fd() to reset the timeout ever time data is written to the net.
14404 *) timeout() signal handler now checks for SIGPIPE and reports
14405 lost connections in a more user friendly way. [Rob Hartill]
14407 *) Location of the "scoreboard" file which used to live in /tmp is
14408 now configurable (for OSes that can't use mmap) via ScoreBoardFile
14409 which works similar to PidFile (in httpd.conf) [Rob Hartill]
14411 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
14413 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
14414 which caused a SEGV with cookies enabled
14416 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
14419 *) Log the UNIX textual error returned by some system calls, in
14420 particular errors from accept() [David Robinson]
14422 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
14424 Changes with Apache 1.0.2
14426 *) patch to get Apache compiled on UnixWare 2.x, recommended as
14427 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
14429 *) Fix get_basic_auth_pw() to set the auth_type of the request.
14432 *) past changes to http_config.c to only use the
14433 setrlimit function on systems defining RLIMIT_NOFILE
14434 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
14435 for SUNOS and prototypes the needed functions.
14437 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
14440 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
14442 *) Merge multiple headers from CGI scripts instead of taking last
14443 one. [David Robinson]
14445 *) Add support for SCO 5. [Ben Laurie]
14447 Changes with Apache 1.0.1
14449 *) Silence mod_log_referer and mod_log_agent if not configured
14452 *) Recursive includes can occur if the client supplies PATH_INFO data
14453 and the server provider uses relative links; as file.html
14454 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
14456 *) The replacement for initgroups() did not call {set,end}grent(). This
14457 had two implications: if anything else used getgrent(), then
14458 initgroups() would fail, and it was consuming a file descriptor.
14461 *) On heavily loaded servers it was possible for the scoreboard to get
14462 out of sync with reality, as a result of a race condition.
14463 The observed symptoms are far more Apaches running than should
14464 be, and heavy system loads, generally followed by catastrophic
14465 system failure. [Ben Laurie]
14467 *) Fix typo in license. [David Robinson]
14469 Changes with Apache 1.0.0 23 Nov 1995
14471 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
14473 Changes with Apache 0.8.16 05 Nov 1995
14475 *) New man page for 'httpd' added to support directory [David Robinson]
14477 *) .htgroup files can have more than one line giving members for a
14478 given group (each must have the group name in front), for NCSA
14479 back-compatibility [Robert Thau]
14481 *) Mutual exclusion around accept() is on by default for SVR4 systems
14482 generally, since they generally can't handle multiple processes in
14483 accept() on the same socket. This should cure flaky behavior on
14484 a lot of those systems. [David Robinson]
14486 *) AddType, AddEncoding, and AddLanguage directives take multiple
14487 extensions on a single command line [David Robinson]
14489 *) UserDir can be disabled for a given virtual host by saying
14490 "UserDir disabled" in the <VirtualHost> section --- it was a bug
14491 that this didn't work. [David Robinson]
14493 *) Compiles on QNX [Ben Laurie]
14495 *) Corrected parsing of ctime time format [David Robinson]
14497 *) httpd does a perror() before exiting if it can't log its pid
14498 to the PidFile, to make diagnosing the error a bit easier.
14501 *) <!--#include file="..."--> can no longer include files in the
14502 parent directory, for NCSA back-compatibility. [David Robinson]
14504 *) '~' is *not* escaped in URIs generated for directory listings
14507 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
14509 *) Fixed bug involving handling URIs with escaped %-characters
14510 in redirects [David Robinson]
14512 Changes with Apache 0.8.15 14 Oct 1995
14514 *) Switched to new, simpler license
14516 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
14518 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
14520 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
14522 *) Correctly handles internal redirects to files with names containing '%'
14525 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
14527 *) Use geteuid() rather than getuid() to see if we have root privilege,
14528 so that server correctly resets privilege if run setuid root. [Andrew
14531 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
14534 *) Fix relative URLs in imagemap files [Randy Terbush]
14536 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
14539 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
14540 entries all name the same one. [David Robinson]
14542 *) Fix directory listings with filenames containing unusual characters
14545 *) Better URI-escaping for generated URIs in directories with filenames
14546 containing unusual characters [Ben Laurie]
14548 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
14550 *) Unblock alarms on error return from spawn_child() [David Robinson]
14552 *) Sample Config files have extra note for SCO users [Ben Laurie]
14554 *) Configuration has note for HP-UX users [Rob Hartill]
14556 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
14558 *) Nuked bogus #define in httpd.h [David Robinson]
14560 *) Better test for whether a system has setrlimit() [David Robinson]
14562 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
14564 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
14567 Changes with Apache 0.8.14 19 Sep 1995
14569 *) Compiles on SCO ODT 3.0 [Ben Laurie]
14571 *) AddDescription works (better) [Ben Laurie]
14573 *) Leaves an intelligible error diagnostic when it can't set group
14574 privileges on standalone startup [Andrew Wilson]
14576 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
14577 that machine, which claims to be BSD but does not support RLIMIT.
14580 *) gcc -Wall no longer complains about an unused variable when util.c
14581 is compiled with -DMINIMAL_DNS [Andrew Wilson]
14583 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
14585 Changes with Apache 0.8.13 07 Sep 1995
14587 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
14589 *) Have built-in imagemap code recognize & honor Point directive [James
14592 *) Generate cleaner directory listings in directories with a mix of
14593 long and short filenames [Rob Hartill]
14595 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
14597 *) Properly default ServerName for virtual servers [Robert Thau]
14599 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
14600 Paul Richards and a cast of thousands...]
14602 *) On self-identified BSD systems (we don't try to guess any more),
14603 allocate a few extra file descriptors per virtual host with setrlimit,
14604 if we can, to avoid running out. [Randy Terbush]
14606 *) Write 22-character lock file name into buffer with enough space
14607 on startup [Konstantin Olchanski]
14609 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
14612 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
14614 *) Suppress -Wall warning by initializing variable in negotiation code
14615 [Tobias Weingartner]
14617 Changes with Apache 0.8.12 31 Aug 1995
14619 *) Doesn't pause three seconds after including a CGI script which is
14620 too slow to die off (this is done by not even trying to kill off
14621 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
14622 after the entire document has been processed). [Robert Thau]
14624 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
14626 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
14628 *) Allows .htaccess files to override <Directory> sections naming the
14629 same directory [David Robinson]
14631 *) Removed an efficiency hack in sub_req_lookup_uri which was
14632 causing certain extremely marginal cases (e.g., ScriptAlias of a
14633 *particular* index.html file) to fail. [David Robinson]
14635 *) Doesn't log an error when the requested URI requires
14636 authentication, but no auth header line was supplied by the
14637 client; this is a normal condition (the client doesn't no auth is
14638 needed here yet). [Robert Thau]
14640 *) Behaves more sanely when the name server loses its mind [Sean Welch]
14642 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
14644 *) RFC931 code no longer passes out name of prior clients on current
14645 requests if the current request came from a server that doesn't
14646 do RFC931. [David Robinson]
14648 *) Configuration script accepts "Module" lines with trailing whitespace.
14651 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
14653 *) Cleaned up comments in mod_cgi.c [Robert Thau]
14655 Changes with Apache 0.8.11 24 Aug 1995
14657 *) Wildcard <Directory> specifications work. [Robert Thau]
14659 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
14661 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
14662 the file being requested itself, in addition to the directories leading
14663 up to it. [Robert Thau]
14665 *) Logs access failures due to symlink checks or invalid client address
14666 in the error log [Roy Fielding, Robert Thau]
14668 *) Symlink checks deal correctly with systems where lstat of
14669 "/path/to/some/link/" follows the link. [Thau, Fielding]
14671 *) Doesn't reset DirectoryIndex to 'index.html' when
14672 other directory options are set in a .htaccess file. [Robert Thau]
14674 *) Clarified init code and nuked bogus warning in mod_access.c
14675 [Florent Guillaume]
14677 *) Corrected several directives in sample srm.conf
14678 --- includes corrections to directory indexing icon-related directives
14679 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
14680 icons for encodings right, and turning on AddEncoding by default).
14683 *) Corrected descriptions of args to AddIcon and AddAlt in command table
14686 *) INSTALL & README mention "contributed modules" directory [Brian
14689 *) Fixed English in the license language... "for for" --> "for".
14692 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
14693 mod_alias.c, merging it almost completely with handling of Alias, and
14694 adding a 'notes' field to the request_rec which allows the CGI module
14695 to discover whether the Alias module has put this request through
14696 ScriptAlias (which it needs to know for back-compatibility, as the old
14697 NCSA code did not check Options ExecCGI in ScriptAlias directories).
14700 Changes with Apache 0.8.10 18 Aug 1995
14702 *) AllowOverride applies to the named directory, and not just
14703 subdirectories. [David Robinson]
14705 *) Do locking for accept() exclusion (on systems that need it)
14706 using a special file created for the purpose in /usr/tmp, and
14707 not the error log; using the error log causes real problems
14708 if it's NFS-mounted; this is known to be the cause of a whole
14709 lot of "server hang" problems with Solaris. [David Robinson;
14710 thanks to Merten Schumann for help diagnosing the problem].
14712 Changes with Apache 0.8.9 12 Aug 1995
14714 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
14716 *) Nested includes see environment variables of the including document,
14717 for NCSA bug-compatibility (some sites have standard footer includes
14718 which try to print out the last-modified date). [Eric Hagberg/Robert
14721 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
14722 URI as a CGI script, even if it would have been treated as something
14723 else if requested directly, for NCSA back-compatibility. (Note that
14724 this means that people who know the name of the script can see the
14725 code just by asking for it). [Robert Thau]
14727 *) New version of dbmmanage script included in support directory as
14730 *) Check if scoreboard file couldn't be opened, and say so, rather
14731 then going insane [David Robinson]
14733 *) POST to CGI works on A/UX [Jim Jagielski]
14735 *) AddIcon and AddAlt commands work properly [Rob Hartill]
14737 *) NCSA server push works properly --- the Arena bug compatibility
14738 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
14739 if you still want the workaround). [Rob Hartill]
14741 *) If client didn't submit any Accept-encodings, ignore encodings in
14742 content negotiation. (NB this will all have to be reworked anyway
14743 for the new HTTP draft). [Florent Guillaume]
14745 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
14747 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
14749 *) Give Redirect priority over Alias, for NCSA bug compatibility
14752 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
14753 paralleling earlier bug fix for CGI [David Robinson]
14755 *) If DBM auth is improperly configured, report a server error and don't
14758 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
14759 it seems to work well enough without it (even in a 10 hits/sec
14760 workout), and the overhead for the locking under A/UX is
14761 alarmingly high (though it is very low on other systems).
14762 [Eric Hagberg, Jim Jagielski]
14764 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
14766 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
14767 Behlendorf/Eric Hagberg]
14769 *) More improvements to default Configuration for A/UX [Jim Jagielski]
14771 *) Compiles clean on NEXT [Rob Hartill]
14773 *) Compiles clean on SGI [Robert Thau]
14775 Changes with Apache 0.8.8 08 Aug 1995
14777 *) SunOS library prototypes now never included unless explicitly
14778 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
14779 people using GNU libc on SunOS are screwed by prototypes for the
14782 (Those who wish to compile clean with gcc -Wall on a standard
14783 SunOS setup need the prototypes, and may obtain them using
14784 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
14785 with nonstandard libraries are presumably competent to make their
14788 *) Strips trailing '/' characters off both args to the Alias command,
14789 to make 'Alias /foo/ /bar/' work.
14791 Changes with Apache 0.8.7 03 Aug 1995
14793 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
14794 [reported by David Robinson]
14796 *) Compiles clean on OSF/1 [David Robinson]
14798 *) Added some of the more recent significant changes (AddLanguage stuff,
14799 experimental LogFormat support) to CHANGES file in distribution root
14802 Changes with Apache 0.8.6 02 Aug 1995
14804 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
14805 (If you actually wanted a conditional GET which bypassed the cache, you
14806 couldn't get it). [Reported by Roy Fielding]
14808 *) Properly terminate headers on '304 Not Modified' replies to conditional
14809 GETs --- no browser we can find cares much, but the CERN proxy chokes.
14810 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
14812 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
14814 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
14815 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
14816 and older versions don't set the __SUNPRO_C preprocessor variable). On
14817 all other systems, these are never used anyway. [Reported by Mark Cox].
14819 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
14821 Changes with Apache 0.8.5 01 Aug 1995
14823 *) Added last-minute configurable log experiment, as optional module
14825 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
14826 properly. (One-line fix to http_protocol.c).
14828 *) Work around bogus behavior when reloading from Netscape.
14829 It's Netscape's bug --- for some reason they expect a request with
14830 If-modified-since: to not function as a conditional GET if it also
14831 comes with Pragma: no-cache, which is way out of line with the HTTP
14832 spec (according to Roy Fielding, the redactor).
14834 *) Added parameter to set maximum number of server processes.
14836 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
14839 *) IdentityCheck bugfix [Chuck Murcko].
14841 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
14843 *) More sample config file corrections; add extension to AddType for
14844 *.asis, move AddType generic description to its proper place, and
14845 fix miscellaneous typos. [ Alexei Kosut ]
14847 *) Deleted the *other* reference to the regents from the Berkeley
14848 legal disclaimer (everyplace).
14850 *) Nuked Shambhala name from src/README; had already cleaned it out
14851 of everywhere else.
14853 Changes with Apache 0.8.4
14855 *) Changes to server-pool management parms --- renamed current
14856 StartServers to MinSpareServers, created separate StartServers
14857 parameter which means what it says, and renamed MaxServers to
14858 MaxSpareServers (though the old name still works, for NCSA 1.4
14859 back-compatibility). The old names were generally regarded as
14860 too confusing. Also altered "docs" in sample config files.
14862 *) More improvements to default config files ---
14863 sample directives (commented out) for XBitHack, BindAddress,
14864 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
14865 defaults, AddTypes for send-as-is and imagemap magic types, and
14866 improvements to samples for DirectoryIndex [Alexei Kosut]
14868 *) Yet more improvements to default config files --- changes to
14869 Alexei's sample AddLanguage directives, and sample LanguagePriority
14870 [ Florent Guillaume ]
14872 *) Set config file locations properly if not set in httpd.conf
14875 *) Don't escape URIs in internal redirects multiple times; don't
14876 do that when translating PATH_INFO to PATH_TRANSLATED either.
14879 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
14881 Changes with Apache 0.8.3
14883 *) Edited distribution README to *briefly* summarize installation
14884 procedures, and give a pointer to the INSTALL file in the src/
14887 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
14888 recent NCSA distributions.
14890 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
14891 exist for the same directory, use both and don't segfault. [Reported
14894 *) Proper makefile dependencies [David Robinson]
14896 *) Note (re)starts in error log --- reported by Rob Hartill.
14898 *) Only call no2slash() after get_path_info() has been done, to
14899 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
14900 reported by Andrew Wilson, though this one is probably a real bug]
14902 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
14903 dump core when Referer is not supplied. [Randy Terbush]
14905 *) Lightly edited sample config files to refer people to our documentation
14906 instead of NCSA's, and to list Rob McCool as *original* author (also
14907 deleted his old, and no doubt non-functional email address). Would be
14908 nice to have examples of new features...
14910 Changes with Apache 0.8.2 19 Jul 1995
14912 *) Added AddLanuage code [Florent Guillaume]
14914 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
14916 *) All sorts of problems when MultiViews finds a directory. It would
14917 be nice if mod_dir.c was robust enough to handle that, but for now,
14918 just punt. [reported by Brian Behlendorf]
14920 *) Wait for all children on restart, to make sure that the old socket
14921 is gone and we can reopen it. [reported by Randy Terbush]
14923 *) Imagemap module is enabled in default Configuration
14925 *) RefererLog and UserAgentLog modules properly default the logfile
14928 *) Mark Cox's mod_cookies added to the distribution as an optional
14929 module (commented out in the default Configuration, and noted as
14930 an experiment, along with mod_dld). [Mark Cox]
14932 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
14934 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
14936 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
14938 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
14941 Changes with Apache 0.8.1
14943 *) New imagemap module [Randy Terbush]
14945 *) Replacement referer log module with NCSA-compatible RefererIgnore
14946 [Matthew Gray again]
14948 *) Don't mung directory listings with very long filenames.
14949 [Florent Guillaume]
14951 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
14953 *) New config script. See INSTALL for info. [Robert Thau]
14955 *) Scoreboard mechanism for regulating the number of extant server
14956 processes. MaxServers and StartServers defaults are the same as
14957 for NCSA, but the meanings are slightly different. (Actually,
14958 I should probably lower the MaxServers default to 10).
14960 Before asking for a new connection, each server process checks
14961 the number of other servers which are also waiting for a
14962 connection. If there are more than MaxServers, it quietly dies
14963 off. Conversely, every second, the root, or caretaker, process
14964 looks to see how many servers are waiting for a new connection;
14965 if there are fewer than StartServers, it starts a new one. This
14966 does not depend on the number of server processes already extant.
14967 The accounting is arranged through a "scoreboard" file, named
14968 /tmp/htstatus.*, on which each process has an independent file
14969 descriptor (they need to seek without interference).
14971 The end effect is that MaxServers is the maximum number of
14972 servers on an *inactive* server machine, but more will be forked
14973 off to handle unusually heavy loads (or unusually slow clients);
14974 these will die off when they are no longer needed --- without
14975 reverting to the overhead of full forking operation. There is a
14976 hard maximum of 150 server processes compiled in, largely to
14977 avoid forking out of control and dragging the machine down.
14978 (This is arguably too high).
14980 In my server endurance tests, this mechanism did not appear to
14981 impose any significant overhead, even after I forced it to put the
14982 scoreboard file on a normal filesystem (which might have more
14983 overhead than tmpfs). [Robert Thau]
14985 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
14988 *) Read .htaccess files even in directory with <Directory> section.
14989 (Former incompatibility noted on mailing list, now fixed). [Robert
14992 *) "HEAD /" gives the client a "Bad Request" error message, rather
14993 than trying to send no body *and* no headers. [Cliff Skolnick].
14995 *) Don't produce double error reports for some very obscure cases
14996 mainly involving auth configuration (the "all modules decline to
14997 handle" case which is a sure sign of a server bug in most cases,
14998 but also happens when authentication is badly misconfigured).
15001 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
15002 it's *for*, and this sort of thing really shouldn't be cluttering
15003 up the Makefile). [Robert Thau]
15005 *) Incidental code cleanups in http_main.c --- stop dragging
15006 sa_client around; just declare it where used. [Robert Thau]
15008 *) Another acc-related fix. (It doesn't like const char
15009 in some places...). [Mark Cox]
15011 Changes with Shambhala 0.6.1 13 Jul 1995
15013 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
15014 Also, fixed auth typo in http_protocol.c unmasked by this fix.
15016 *) Compiles clean with acc on SunOS [Paul Sutton]
15018 *) Reordered modules in modules.c so that Redirect takes priority
15019 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
15020 believe it or not, he has an actual site with a ScriptAlias and
15021 a Redirect declared for the *exact same directory*. Even *my*
15022 compatibility fetish wouldn't motivate me to fix this if the fix
15023 required any effort, but it doesn't, so what the hey.
15025 *) Fixed to properly default several server_rec fields for virtual
15026 servers from the corresponding fields in the main server_rec.
15027 [Cliff Skolnick --- 'port' was a particular irritant].
15029 *) No longer kills off nph- child processes before they are
15030 finished sending output. [Matthew Gray]
15032 Changes with Shambhala 0.6.0 10 Jul 1995
15034 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
15035 the connection to the client in an "aborted" state, but otherwise
15036 allow whatever handlers are running to clean up. hard_timeout()s
15037 abort the request in progress completely; anything not tied to some
15038 resource pool cleanup will leak. They're still around because I
15039 haven't yet come up with a more elegant way of handling
15040 timeouts when talking to something that isn't the client. The
15041 default_handler and the dir_handler now use soft timeouts, largely
15042 so I can test the feature. [Robert Thau]
15044 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
15045 the case of log handlers dying prematurely is probably handled VERY
15046 gracelessly at this point, and if the logger stops reading input,
15047 the server will hang. (It is known to correctly restart the
15048 logging process on server restart; this is (should be!) going through
15049 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
15050 script). [Robert Thau]
15052 *) asis files supported (new module). [Robert Thau]
15054 *) IdentityCheck code is compiled in, but has not been tested. (I
15055 don't know anyone who runs identd). [Robert Thau]
15057 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
15058 came in with the request, for NCSA bug-compatibility. [Robert Thau]
15060 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
15062 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
15063 as timeouts are not in scope. [Robert Thau]
15065 *) quoted-string args in config files now handled correctly (doesn't drop
15066 the last character). [Robert Thau; reported by Randy Terbush]
15068 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
15069 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
15071 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
15072 default default type); the former default default behavior when all
15073 type-checkers defaulted had been a core dump. [Paul Sutton]
15075 *) Copy filenames out of the struct dirent when indexing
15076 directories. (On Linux, readdir() returns a pointer to the same
15077 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
15079 Changes with Shambhala 0.5.3 [not released]
15081 *) Default response handler notes "file not found" in the error log,
15082 if the file was not found. [Cliff Skolnick].
15084 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
15085 code no longer sets up bogus PATH_INFO which fakes out the directory
15086 handler). [Cliff Skolnick]
15088 Changes with Shambhala 0.5.2 06 Jul 1995
15090 *) Changes to http_main.c --- root server no longer plays silly
15091 games with SIGCHLD, and so now detects and replaces dying
15092 children. Child processes just die on SIGTERM, without taking
15093 the whole process group with them. Potential problem --- if any
15094 child process refuses to die, we hang in restart.
15095 MaxRequestsPerChild may still not work, but it certainly works
15096 better than it did before this! [Robert Thau]
15098 *) mod_dir.c bug fixes: ReadmeName and HeaderName
15099 work (or work better, at least); over-long description lines
15100 properly terminated. [Mark Cox]
15102 *) http_request.c now calls unescape_url() more places where it
15103 should [Paul Sutton].
15105 *) More directory handling bugs (reported by Cox)
15106 Parent Directory link is now set correctly. [Robert Thau]
15108 Changes with Shambhala 0.5.1 04 Jul 1995
15110 *) Generalized cleanup interface in alloc.c --- any function can be
15111 registered with alloc.c as a cleanup for a resource pool;
15112 tracking of files and file descriptors has been reimplemented in
15113 terms of this interface, so I can give it some sort of a test.
15116 *) More changes in alloc.c --- new cleanup_for_exec() function,
15117 which tracks down and closes all file descriptors which have been
15118 registered with the alloc.c machinery before the server exec()s a
15119 child process for CGI or <!--#exec-->. CGI children now get
15120 started with exactly three file descriptors open. Hopefully,
15121 this cures the problem Rob H. was having with overly persistent
15122 CGI connections. [Robert Thau]
15124 *) Mutual exclusion around the accept() in child_main() --- this is
15125 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
15126 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
15127 This uses fcntl(F_SETLK,...) on the error log descriptor because
15128 flock() on that descriptor won't work on systems which have BSD
15129 flock() semantics, including (I think) Linux 1.3 and Solaris.
15131 This does work on SunOS (when the server is idle, only one
15132 process in the pool is waiting on accept()); it *ought* to work
15133 on the other systems. [Robert Thau]
15135 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
15137 *) sizeof(*sa_client) bugfix from [Rob Hartill]
15139 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
15141 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
15142 be unnecessary if I go to the revised timeout-handling scheme).
15145 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
15146 string) even if none came in with the request. [Robert Thau]
15148 *) CHANGES file added to distribution ;-).
15150 Changes with Shambhala 0.4.5
15152 *) mod_dld --- early dynamic loading support [rst]
15153 *) Add wildcard content handlers for XBITHACK; default_hander now
15154 invoked with that mechanism (as a handler hanging off mod_core) [rst]
15155 *) XBITHACK supported as a wildcard content-handler, and
15156 configurable at run-time (not just at compile time, as in the
15157 "patchy server" releases) [rst]
15159 Changes with Shambhala 0.4.4 30 Jun 1995
15161 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
15162 *) Handle Addtype x/y .z [rst, reported by Cox]
15164 Changes with Shambhala 0.4.3
15166 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
15167 synonymous [rst, terbush]
15169 Changes with Shambhala 0.4.1 28 Jun 1995
15171 *) First-cut virtual host implementation; some refit in the config
15172 reading code, and log management, was necessary to support this [rst]
15173 *) Sub-pool machinery, originally added to avoid excessive storage
15174 allocation on listings of large directories (which turned out to
15175 be the problem that the 0.3 storage accounting was added to
15176 find). Subrequests and mod_dir changed to use subpools. [rst]
15177 *) More memory debugging --- free list consistency checks. [rst]
15178 *) Added err_headers to request_rec, with support elsewhere [rst]
15179 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
15181 Changes with Shambhala 0.3 19 Jun 1995
15183 *) Switch ONE_PROCESS to a runtime command-line option (-X)
15184 *) Don't compile in mod_ai_backcompat by default
15185 *) Switch name of server from Apache to Shambhala in Makefile
15186 *) Add some accounting routines to track memory usage in the pools,
15189 Changes with Shambhala 0.2
15191 *) Set DOCUMENT_ROOT CGI variable
15192 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
15193 *) Add critical section protection to handling of cleanup structures
15195 *) Significant code reorg within the server core to group related
15196 functions together [rst]
15197 *) Correctly handle clients that hang up before sending any request
15199 *) Replace dying child processes. [rst]
15201 Changes with Shambhala 0.1 12 Jun 1995
15203 Major rewrite of the pre-existing "patchy server" codebase, by
15204 Robert Thau (rst). Significant portions of the server code, such
15205 as configuration-file handling and HTTP authentication support,
15206 were ripped out and rewritten from scratch. Code that was not
15207 completely rewritten was significantly altered.
15209 Major changes with this release include:
15211 *) Introduction of the module API; in request handling, the central
15212 machinery just dispatches to various modules, which actually do
15213 most of the work. Configuration handling is similar --- modules
15214 declare their own commands, and the central machinery just
15215 dispatches to them.
15217 API features from shambhala/0.1 were substantially unchanged in
15218 Apache 1.0 and 1.1. (1.0 API features not yet present in this
15219 release, such as wildcard handlers and subpools, were added in
15220 subsequent Shambhala releases, and were also generally rst's
15223 *) This release included the following modules:
15225 mod_access (access control --- allow and deny directives),
15226 mod_alias (Alias and Redirect commands),
15227 mod_auth (straight HTTP authentication, based on flat-files)
15228 mod_auth_dbm (same, with dbm files)
15229 mod_cgi (CGI scripts and, in this release, ScriptAlias)
15230 mod_common_log (CLF access logs; later renamed mod_log_common)
15231 mod_dir (directory indexing)
15232 mod_include (server-side includes)
15233 mod_mime (AddType directives)
15234 mod_negotiation (content negotiation)
15235 mod_userdir (support for users' public_html directories)
15237 It also included a mod_ai_backcompat, which was a private hack
15238 for back-compatibility with rst's own AI-lab servers.
15240 All of these modules were substantially complete, and functional
15241 or nearly so (a few, which implemented features not in use at
15242 Thau's site, required patches of a few lines).
15244 *) sub-request machinery, to allow modules to determine how other
15245 modules would assign MIME types to a given file, or optionally
15246 serve its content (this is heavily used by mod_dir, mod_include
15247 and mod_negotiation).
15249 *) Resource pool system for keeping track of memory allocated and
15250 files opened in service of a particular request. Much of the
15251 code in the modules (when they weren't rewrites) was adjusted to
15252 replace a pervasive convention of using fixed-size buffers on
15253 the stack with an equally pervasive convention of using memory
15254 allocated with palloc().
15256 *) Reorganization of data structures associated with a given
15257 request to eliminate use of global variables and the troublesome
15258 unmunge_name function (used in NCSA and early Apache releases to
15259 attempt to determine the URI which mapped to a given filename
15260 --- a difficult proposition, given that it is easy to produce
15261 setups in which multiple URIs map to the same file).
15263 *) Source files renamed and rearranged
15265 *) Very simple pre-forking behavior --- parent process forked off a
15266 fixed number of children, and then just waited for SIGHUP.
15268 *) Other more minor changes too numerous to list.
15270 This release included modified versions of a lot of code from the
15271 Apache 0.6.4 public release, plus an early pre-forking patch
15272 codeveloped by Robert Thau and Rob Hartill.
15274 Changes with Apache 0.7.3 20 Jun 1995
15276 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
15277 were incorporated by Rob Hartill on the main branch while Robert Thau
15278 worked on the Shambhala rewrite above. Most were merged into the
15279 Shambala architecture after Apache 0.8.0.
15281 Changes with Apache 0.6.4 13 May 1995
15283 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
15286 Changes with Apache 0.5.1 10 Apr 1995
15288 Changes with Apache 0.4 02 Apr 1995
15290 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
15293 Changes with Apache 0.3 24 Mar 1995
15295 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
15298 Changes with Apache 0.2 18 Mar 1995
15300 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
15301 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
15302 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
