60 [Jan Kratochvil <rcpt-dev.AT.httpd.apache.org jankratochvil.net>]
62 *) Restructured mod_auth_ldap to fit the new authentication model.
63 The module is now called authnz_ldap and has been moved out of
64 the modules/experimental area and into modules/aaa with the other
65 auth modules. Both the authn_ldap provider and the authz_ldap
66 handler are contained within the authnz_ldap module. The
67 authz_ldap handler introduces 3 new "requires" values for handling
68 authorization. These handlers are ldap-user, ldap-group and
69 ldap-dn. [Brad Nicholes]

85 use apr_socket_create_ex for 0.9.x
88 *) Added proxy_ajp.c module for proxy support to ajp:// backends.
91 *) Fixes the build of proxy on Windows. Since the proxy_module is declared
92 as extern using AP_MODULE_DECLARE_DATA that expands to dllexport, there
93 is a LNK2001 error when building proxy_http. [Mladen Turk]
95 *) Remove LDAP toolkit specific code from util_ldap and mod_auth_ldap.
98 *) Remove deprecated/removed APR_STATUS_IS_SUCCESS(). [Justin Erenkrantz]

127 to enable Header and RequestHeader directives to be used to set up
128 testcases for pre-fixups request phases [Nick Kew]
130 *) mod_proxy: multiple bugfixes, principally support cookies in
131 ProxyPassReverse, and don't canonicalise URL passed to backend.
132 Documentation correspondingly updated. [Nick Kew <nick webthing.com>]
134 *) mod_deflate: support gzip flags in inflate_out_filter
135 [Nick Kew <nick webthing.com>]
137 *) Drop the ErrorHeader directive which turned out to be a misnomer.
138 Instead there's a new optional flag for the Header directive
139 ('always'), which keeps the former ErrorHeader functionality.
142 *) mod_deflate: Don't deflate responses with zero length
143 e.g. proxied 304's [Allan Edwards]

153 *) mod_ssl: Drop support for the CompatEnvVars argument to
154 SSLOptions, which was never actually implemented in 2.0.

158 even when Accept-Encoding is not present. [Justin Erenkrantz]
160 *) Pass environment variables through to piped loggers and start
161 them via the shell, resolving regressions since 1.3. PR 28815
162 [Ken Coar, Jeff Trawick]
164 *) External rewrite map responses are no longer limited to 2048
167 *) Proxy server was deleting cookies that Apache had already
168 assigned if the origin server had set any cookies. PR 27023.
171 *) Removed old and unmaintained ap_add_named_module API and changed
172 the following APIs to return an error instead of hard exiting:

207 directive (previously NetWare-only) to override default thread
208 stack size for threads which handle client connections. Required
209 for some third-party modules on platforms with small default
210 thread stack size. [Jeff Trawick]
212 *) minor mod_auth_basic and mod_auth_digest sync. mod_auth_basic
213 now populates r->user with the (possibly unauthenticated) user,
214 and mod_auth_digest returns 500 when a provider returns
218 *) The whole codebase was relicensed and is now available under
219 the Apache License, Version 2.0 (http://www.apache.org/licenses).

232 mode. PR 25635. [André Malo]
234 *) mod_rewrite: Introduce the ability to force a content handler via
235 the [handler=...] flag. [André Malo]

297 *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
298 PR 14223. [André Malo]
300 *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously

413 atomic operations for higher concurrency. [Brian Pane]
415 *) Allow 'make depend' to work with non-GCC compilers.
418 *) If an httpd.conf has commented out AddModule directives,

1689 in most configurations. [Bill Stoddard]
1691 *) mod_cache: Fix PR 15113, a core dump in cache_in_filter when
1692 a redirect occurs. The code was passing a format string and
1693 integer to apr_pstrcat. Changed to apr_psprintf.
1696 *) Replace APU_HAS_LDAPSSL_CLIENT_INIT with APU_HAS_LDAP_NETSCAPE_SSL
1697 as set by apr-util in util_ldap.c. This should allow mod_ldap
1698 to work with the Netscape/Mozilla LDAP library. [Øyvin Sømme

1718 *) mod_log_config: Allow '%%' escaping in CustomLog format
1719 strings to insert a literal, single '%'.
1720 [André Malo <nd perlig.de>]
1722 *) mod_autoindex: AddDescription directives for directories
1723 now work as in Apache 1.3, where no trailing '/' is
1724 specified on the directory name. Previously, the trailing
1725 '/' *had* to be specified, which was incompatible with
1726 Apache 1.3. PR 7990 [Jeff Trawick]
1728 *) Fix for PR 14556. The expiry calculations in mod_cache were
1729 trying to perform "now + ((date - lastmod) * factor)" where
1730 date == lastmod resulting in "now + 0". The code now follows
1731 the else path (using the default expiration) if date is
1732 equal to lastmod. [Sergey <rx armstrike.com>, Paul J. Reder]
1734 *) Use AP_DECLARE in the debug versions of ap_strXXX in case the
1735 default calling convention is not the same as the one used by
1736 AP_DECLARE. [Juan Rivera <Juan.Rivera citrix.com>]
1738 *) mod_cache: Don't cache response header fields designated

1752 *) Add --[enable|disable]-v4-mapped configure option to control
1753 whether or not Apache expects to handle IPv4 connections
1754 on IPv6 listening sockets. Either setting will work on
1755 systems with the IPV6_V6ONLY socket option. --enable-v4-mapped
1756 must be used on systems that always allow IPv4 connections on
1757 IPv6 listening sockets. PR 14037 (Bugzilla), PR 7492 (Gnats)
1760 *) This fixes a problem where the underlying cache code
1761 indicated that there was one more element on the cache
1762 than there actually was. This happened since element 0
1763 exists but is not used. This code allocates the correct
1764 number of useable elements and reports the number of
1765 actually used elements. The previous code only allowed
1766 MCacheMaxObjectCount-1 objects to be stored in the
1767 cache. [Paul J. Reder]

1802 once per worker, indicating that the CacheRoot needs to be set.
1805 *) Fix a bug where we keep files open until the end of a
1806 keepalive connection, which can result in:
1807 (24)Too many open files: file permissions deny server access
1808 especially on threaded servers. [Greg Ames, Jeff Trawick]
1810 *) Fix a bug in which mod_proxy sent an invalid Content-Length
1811 when a proxied URL was invoked as a server-side include within
1812 a page generated in response to a form POST. [Brian Pane]
1814 *) Added code to process min and max file size directives and to
1815 init the expirychk flag in mod_disk_cache. Added a clarifying
1816 comment to cache_util. [Paul J. Reder]

1858 *) Change the CacheRoot processing to check for a required
1859 value at config time. This saves a lot of wasted processing
1860 if the mod_disk_cache module is loaded but no CacheRoot
1861 was provided. This fix also adds code to log an error
1862 and avoid useless pallocs and procesing when the computed
1863 cache file name cannot be opened. This also updates the
1864 docs accordingly. [Paul J. Reder]

1906 vulnerability exposed by the directive 'UseCanonicalName Off'.
1907 Also HTML-escape the SERVER_NAME environment variable for CGI

2091 *) Performance improvement for keepalive requests: when setting
2092 aside a small file for potential concatenation with the next
2093 response on the connection, set aside the file descriptor rather
2094 than copying the file into the heap. [Brian Pane]
2096 *) Modified version check on openssl so that it finds the executable
2097 first and then performs a check of the version, only warning the
2098 user if they chose, or we selected, an old version of OpenSSL.
2099 This change also allows the code to work for non-openssl libraries

2209 *) Performance improvements for the code that reads request
2210 headers (ap_rgetline_core() and related functions) [Brian Pane]
2212 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
2213 to configure the maximum amount of memory the allocators will
2214 hold on to for reuse. Anything over the MaxMemFree threshold

2223 *) Add a filter_init parameter to the filter registration functions

2225 are invoked. This resolves a problem where mod_include requests
2226 would incorrectly return a 304. [Justin Erenkrantz]
2228 *) Fix a long-standing bug in 2.0, CGI scripts were being called
2229 with relative paths instead of absolute paths. Apache 1.3 used
2230 absolute paths for everything except for SuExec, this brings back
2231 that standard. [Ryan Bloom]

2243 *) Support WinNT CGI invocation through ScriptInterpreterSource
2244 'registry' for script interpreter paths and names with non-ascii
2245 characters in the executable filepath. [William Rowe]
2247 *) Support the -w flag on to keep the Win32 console open on error.
2250 *) Normalize the hostname value in the request_rec to all-lowercase
2251 [Perry Harrington <pedward webcom.com>]
2253 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
2254 extended characters (non US-ASCII) in non-utf8 format. This brings
2255 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
2256 to the cgi application itself. [William Rowe]
2258 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
2259 modules to bring them up to the current apr/apr-util APIs.
2262 *) Fix segfault in mod_mem_cache most frequently observed when
2263 serving the same file to multiple clients on an MP machine.

2279 *) Improve ap_get_client_block implementation by using APR-util brigade
2280 helper functions and relying on current filter assumptions.
2283 Changes with Apache 2.0.39
2285 *) Fixed a build problem in htpasswd.c on Win32.
2286 [Guenter Knauf <eflash gmx.net>, Cliff Woolley]
2288 Changes with Apache 2.0.38
2290 *) Rewrite htpasswd to use APR. The removes the annoying warning about
2291 tmpnam being unsafe. [Ryan Bloom]
2293 *) We must set the MIME-type for .shtml files to text/html if we want them
2294 to be parsed for SSI tags. Add the config for that to the default
2295 config file so that it is easier to enable .shtml parsing.

2299 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
2301 *) Make the default_handler catch all requests that aren't served by
2302 another handler. This also gets us to return a 404 if a directory
2303 is requested, there is no DirectoryIndex, and mod_autoindex isn't
2304 loaded. [Justin Erenkrantz]
2306 *) Fixed the handling of nested if-statements in shtml files.
2307 PR 9866 [Brian Pane]
2309 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
2310 into a directory different from the one that was configured. This
2311 also mirrors the root= feature from 1.3. We cannot use prefix=,
2312 because both APR and APR-util resolve their installation paths at
2313 configuration time. This means that there is no variable prefix
2314 to replace. [Andreas Hasenack <andreas netbank.com.br>]
2316 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
2317 These levels of AIX don't have a thundering herd problem with
2318 accept(). [Jeff Trawick]
2320 *) prefork MPM: Ignore mutex errors during graceful restart. For
2321 certain types of mutexes (particularly SysV semaphores), we
2322 should expect to occasionally fail to obtain or release the
2323 mutex during restart processing. [Jeff Trawick]
2325 *) Fix install-bindist.sh so that it finds any perl instead of just
2326 early perl 5.x versions. This is consistent with a build/install
2327 from source, and it allows the perl scripts installed by a bindist
2328 to work on systems with perl 5.6. [Jeff Trawick]
2330 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
2331 Tru64 (and probably some other platforms). [Jeff Trawick]
2333 *) Allow CGI scripts to return their Content-Length. This also fixes a

2346 authentication is used with 'SSLOptions +OptRenegotiate' enabled
2347 and a client cert was found in the ssl session cache.
2349 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
2350 session cache when there is no cert chain in the cache. prior to
2351 the fix this situation would result in a FORBIDDEN response and
2352 error message "Cannot find peer certificate chain"

2356 one was already sent. PR 9644 [Jeff Trawick]

2396 it has sent an EOS bucket up the stack, if so, it will only ever
2397 send an EOS bucket for this request.

2400 *) Remove all special mod_ssl URIs. This also fixes the bug where
2401 redirecting (.*) will allow an SSL protected page to be viewed
2402 without SSL. [Ryan Bloom]
2404 *) Fix the binary build install script so that the build logic
2405 created by "apxs -g" will work when the user has a binary
2406 build. [Jeff Trawick]
2408 *) Allow instdso.sh to work with full paths to the shared module.
2411 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
2412 in module for NetWare [Brad Nicholes]
2414 *) Changed cgi and piped log behavior to accept 65536 characters
2415 on Win32 (matching Linux) before deadlocking between outputing
2416 client stdin, slurping the output from stdout and then the stderr
2417 stream. PR 8179 [William Rowe]
2419 *) Fixed Win32 wintty.exe support to assure the window title is valid.
2420 Elimiates possible gpfault or garbage title without the -t option.
2423 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
2424 brigades and input filters. [Justin Erenkrantz]
2426 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
2427 body. [Justin Erenkrantz]
2429 *) NetWare: Piping log entries through RotateLogs using the
2430 CustomLogs directive is finally supported now that we have

2453 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
2454 stripping the content_type from cached responses.
2457 *) apachectl passes through any httpd options. Note: apachectl
2458 should be used in preference to httpd since it ensures that any
2459 appropriate environment variables have been set up.

2505 It is currently ignored and it will be removed in a future release
2506 of Apache. [Jeff Trawick]
2508 *) Removed documentation references to the no-longer-supported
2509 "make certificate" feature of mod_ssl for Apache 1.3.x. Test
2510 certificates, if truly desired, can be generated using openssl
2511 commands. PR 8724. [Cliff Woolley]
2513 *) Remove SSLLog and SSLLogLevel directives in favor of having
2514 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
2516 *) OS/390: LIBPATH no longer has to be manually uncommented in
2517 envvars to get apachectl to set up httpd properly. [Jeff Trawick]
2519 *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
2520 may now be specified to the <File/Directory > container, rather

2526 *) mod_isapi: Major refactoring of the code to rely on apr internals
2527 rather than MS APIs (using our own mod_isapi.h headers for ISAPI
2528 symbol definitions.) [William Rowe]
2530 *) mod_isapi: Fixed the return string length from GetServerVariable
2531 callback, it was not including the trailing null in the consumed

2690 explicitly tell the server that warning messages should be sent
2691 to the client in addition to being recorded in the error log.
2692 Prior to this change, ap_log_rerror() always sent warning
2693 messages to the client. In one case, a faulty CGI script caused
2694 the server to send a warning message to the client that contained
2695 the full path to the CGI script. This could be considered a
2696 minor security exposure. [Bill Stoddard]
2698 *) mod_autoindex output when SuppressRules was specified would

2794 handle declarations are recognized. This fixes problems loading
2795 mod_autoindex on some platforms. [Brian Havard]
2797 *) add optional fixup hook to proxy [Daniel Lopez <daniel covalent.net>]
2799 *) Remind the admin about the User and Group directives when we are
2800 unable to set permissions on a semaphore. PR 7812 [Jeff Trawick]
2802 *) fix possible compilation problem in ssl_engine_kernel.c. PR 7802
2805 *) fix possible infinite loop in mod_ssl triggered by certain
2806 netscape clients [Doug MacEachern]
2808 *) fix ProxyPass when frontend is https and backend is http
2811 *) Add DASL support to mod_dav
2812 [Sung Kim <hunkim cse.ucsc.edu>]
2814 Changes with Apache 2.0.35
2816 *) mod_rewrite: updated to use the new APR global mutex type.
2819 *) Fixes for mod_include errors on boundary conditions in which
2820 "<!--#" occurs at the very end of a bucket
2821 [Paul Reder, Brian Pane]
2823 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
2824 cause the Apache parent process to run in the foreground (similar to
2825 -DNO_DETACH except that it doesn't switch session ids).
2828 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
2829 for those platforms that support it. If using the default
2830 implementation, this is between pthread and sysvsem in priority.
2831 This implies it's the new default for Darwin. [Jim Jagielski]
2833 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
2834 environment variables in the envvars file. [Jeff Trawick]
2836 *) worker MPM: Don't create a listener thread until we have a worker
2837 thread. Otherwise, in situations where we'll have to wait a while
2838 to take over scoreboard slots from a previous generation, we'll be
2839 accepting connections we can't process yet. [Jeff Trawick]
2841 *) Allow worker MPM to build on systems without pthread_kill().
2842 [Pier Fumagalli, Jeff Trawick]
2844 *) Prevent ap_add_output_filters_by_type from being called in
2845 ap_set_content_type if the content-type hasn't changed.
2848 *) Performance: implemented the bucket allocator made possible by the
2849 API change in 2.0.34. [Cliff Woolley]
2851 *) Don't allow initialization to succeed if we can't get a socket
2852 corresponding to one of the Listen statements. [Jeff Trawick]
2854 Changes with Apache 2.0.34
2856 *) Allow all Perchild directives to accept either numerical UID/GID
2857 or logical user/group names. [Scott Lamb <slamb slamb.org>]
2859 *) Make Perchild compile cleanly and serve pages again. [Ryan Bloom]
2861 *) implement ssl proxy to support ProxyPass / https:// and the
2862 SSLProxy* directives [Doug MacEachern]
2864 *) Update mod_cgid to not do single-byte socket reads for CGI headers
2867 *) Made AB's use of the Host: header rfc2616 compliant
2868 by Taisuke Yamada <tai iij.ad.jp> [Dirk-Willem van Gulik].
2870 *) The old, legacy (and unused) code in which the scoreboard was totally
2871 and completely contained in a file (SCOREBOARD_FILE) has been
2872 removed. This does not affect scoreboards which are *mapped* to
2873 files using named-shared-memory. [Jim Jagielski]
2875 *) Change bucket brigades API to allow a "bucket allocator" to be
2876 passed in at certain points. This allows us to implement freelists
2877 so that we can stop using malloc/free so frequently.
2878 [Cliff Woolley, Brian Pane]
2880 *) Add support for macro expansion within the variable names in
2881 <!--#echo--> and <!--#set--> directives [Brian Pane]
2883 *) Fix some mod_include segfaults [Cliff Woolley, Brian Pane, Brad Nicholes]
2885 *) Update the "RedHat" Layout to match Red Hat Linux version 7. PR BZ-7422
2888 *) add compat layer to support RSA SSLC 1.x and 2.x in mod_ssl
2889 [Jon Travis, John Barbee, William Rowe, Ryan Bloom, Doug MacEachern]
2891 *) Add a new parameter to the quick_handler hook to instruct
2892 quick handlers to optionally do a lookup rather than actually
2893 serve content. This is the first of several changes required fix
2894 several problems with how quick handlers work with subrequests.
2897 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]
2899 *) [APR-related] The ordering of the default accept mutex method has
2900 been changed to better match what's done in Apache 1.3. The ordering
2901 is now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
2904 *) Ensure that the build/ directory is created when using VPATH.
2907 *) Add some popular types to the mime magic file. PR 7730.
2908 [Linus Walleij <triad df.lth.se>, Justin Erenkrantz]
2910 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
2912 *) When a proxied site was being served, Apache was replacing
2913 the original site Server header with it's own, which is not
2914 allowed by RFC2616. Fixed. [Graham Leggett]
2916 *) Fix a mod_cgid problem that left daemon processes stranded
2917 in some server restart scenarios. [Jeff Trawick]
2919 *) Added exp_foo and rel_foo variables to config_vars.mk for
2920 all Apache and Autoconf path variables (like --sysconfdir,
2921 --sbindir, etc). exp_foo is the "expanded" version, which means
2922 that all internal variable references have been interpolated.
2923 rel_foo is the same as $exp_foo, only relative to $prefix if they
2924 share a common path. [Aaron Bannert]
2926 *) Fix some restart/terminate problems in the worker MPM. Don't
2927 drop connections during graceful restart. [Jeff Trawick]
2929 *) Change the header merging behaviour in proxy, as some headers
2930 (like Set-Cookie) cannot be unmerged due to stray commas in
2931 dates. [Graham Leggett]
2933 *) Be more vocal about what AcceptMutex values we allow, to make
2934 us closer to how 1.3 does it. [Jim Jagielski]
2936 *) Get nph- CGI scripts working again. PRs 8902, 8907, 9983
2939 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
2941 *) Add accessor function to set r->content_type. From now on,
2942 ap_rset_content_type() should be used to set r->content_type.
2943 This change is required to properly implement the
2944 AddOutputFilterByType configuration directive.
2945 [Bill Stoddard, Sander Striker, Ryan Bloom]
2947 *) Add new M_FOO symbols for the WebDAV/DeltaV methods specified by
2948 RFC 3253. Improved the method name/number mapping functions.
2951 *) remove sock_enable_linger from connection.c [Ian Holsman]
2953 *) Fix for virtual host processing where the requested hostname
2954 has a '.' at the end (PR 9187) [Ryan Cruse <ryan estara.com>]
2956 *) mod_dav's APIs for REPORT response handling was changed so that
2957 providers can generate the content directly into the output filter
2958 stack, rather than buffering the response into memory. [Greg Stein]
2960 *) Fix a hang condition with graceful restart and prefork MPM
2961 in the situation where MaxClients is very high but
2962 much fewer servers are actually started at the time of the
2963 restart. [Jeff Trawick]
2965 *) Small performance fixes for mod_include [Brian Pane]
2967 *) Performance improvement for the error logger [Brian Pane]
2969 *) Change configure so that Solaris 8 and above have
2970 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
2971 according to sun people solaris 8+ doesn't have a thundering
2972 herd problem [Ian Holsman]
2974 *) Allow URIs specifying CGI scripts to include '/' at the end
2975 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
2976 which ignore '/' at the end of the names of non-directories).
2977 PR 10138 [Jeff Trawick]
2979 *) implement SSLSessionCache shmht and shmcb based on apr_rmm and
2980 apr_shm. [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
2982 *) Fix apxs -g handling. Move config_vars.mk from the top build
2983 directory to the build directory. PR 10163 [Jeff Trawick]
2985 *) Fix some mod_include problems which broke evaluation of some
2986 expressions. PR 10108 [Jeff Trawick]
2988 *) Fix the calculation of request time in mod_status. [Stas Bekman]
2990 *) Fix the calculation of thread_num in the worker score structure.
2993 *) Use apr_atomic operations in managing the mod_mem_cache
2994 cache_objects for SMP scalability. (see USE_ATOMICS
2995 preprocessor directive in mod_file_cache)
2998 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
2999 preprocessor directive in mod_file_cache)
3002 *) Implement prototype mod_disk_cache for use with mod_cache.
3005 *) Add a missing manualdir entry in the Debian config.layout.
3006 [Thom May <thom planetarytramp.net>]
3008 *) Stop installing libtool for APR and tell APR where it should place
3009 its copy of libtool (via our installbuildpath layout variable).
3012 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
3013 when reading from a remote HTTP server in proxy. [Graham Leggett]
3015 *) Modify receive/send loop in proxy_http and proxy_ftp so that
3016 should it be necessary, the remote server socket is closed before
3017 transmitting the last buffer (set by ProxyIOBufferSize) to the
3018 client. This prevents the backend server from being forced to hang
3019 around while the last few bytes are transmitted to a slow client.
3020 Fix the case where no error checking was performed on the final
3021 brigade in the loop. [Graham Leggett]
3023 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
3024 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
3025 hours. [Graham Leggett, Bill Stoddard]
3027 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
3028 for a undefined variable. [Ian Holsman]
3030 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
3031 when we can't get a socket in the specified address family. We may
3032 have gotten back an IPv6 address first and yet our system is not
3033 configured to allow IPv6 sockets. [Jeff Trawick]
3035 *) Be more careful about recursively removing CVS directories. Make
3036 sure that we aren't cd'ing to their home directory first. PR: 9993
3037 [Aaron Bannert, James LewisMoss <dres lewismoss.net>]
3039 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
3040 [Dirk-Jan Faber <dirk-jan selwerd.nl>, Aaron Bannert,
3041 Thom May <thom planetarytramp.net>]
3043 *) Rename the filter ordering priorities. The recent filtering fixes
3044 have showcased problems with their usage. Therefore, we need to
3045 rename them to increase the clarity. (CONTENT->RESOURCE,
3046 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
3048 Changes with Apache 2.0.33
3050 *) Fix a problem in the new --enable-layout functionality where
3051 it wouldn't allow overrides from variables like --prefix,
3052 --bindir, etc. [Thom May <thom planetarytramp.net>]
3054 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
3055 no longer hangs around waiting for the socket to close before
3056 returning exhaustive data. [Aaron Bannert]
3058 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
3059 [Thom May <thom planetarytramp.net>]
3061 *) Change mod_ssl to always do a full startup/teardown on restarts.
3062 this allows mod_ssl to be added to a server that is already
3063 running and makes it possible to add/change certs/keys after the
3064 server has been started. [Doug MacEachern]
3066 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
3067 This pipe must be a bidirectional 'console' style relay, which
3068 mod_ssl prints all prompts to the pipe's stdin, and reads the
3069 passphrases from the pipe's stdout. [William Rowe]
3071 *) Fix bug where --sysconfdir and --localstatedir were being
3072 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
3075 *) Fix --enable-layout to work again. Caution: When specifying
3076 --enable-layout, common arguments like --prefix, --exec-prefix,
3077 etc. will be ignored and the settings from the layout will be
3078 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]
3081 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
3082 regex pattern matching for the determination of which requests
3083 to use the remote proxy for. [Jim Jagielski]
3085 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
3087 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
3088 cruft in piped logs and rewritemap child processes.
3091 *) All instances of apr_lock_t have been removed and converted
3092 to one of the following new lock APIs: apr_thread_mutex.h,
3093 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
3094 use the apr_lock.h API, as the old API will soon be deprecated.
3097 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
3098 [Ralf S. Engelschall, Cliff Woolley]
3100 *) mod-include: make it handle flush'es and fix the 'false-alarm'
3101 [Justin Erenkrantz, Brian Pane, Ian Holsman]
3103 *) ap_get_*_filter_handle() functions to allow 3rd party modules
3104 to lookup filter handles so they can bypass the filter name
3105 lookup when adding filters to a request (via ap_add_*_filter_handle())
3106 [Ryan Morgan <rmorgan covalent.net>]
3108 *) Fix for multiple file buckets on Win32, where the first file
3109 bucket would cause the immediate closure of the socket on any
3110 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
3112 *) Correct Win32 failure of mmap of a segment beyond start of the
3113 file; fixes large SSL and similar transfers. [William Rowe]
3116 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
3117 multi-process mode to not "daemonize" while detaching from the
3118 controlling terminal. This is necessary for Apache to work with
3119 process-management tools like AIX's "System Resource Controller"
3120 as well as Dan Bernstein's "daemontools".
3121 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
3123 *) Convert mod_auth_digest to use the new apr_global_mutex_t
3124 type. [Aaron Bannert]
3126 *) fix bug in mod-include where it wouldn't send a unmatched
3127 part if it was at the end of a bucket [Ian Holsman]
3129 *) worker MPM: Improve logging of errors with the interface between
3130 the listener thread and worker threads. [Jeff Trawick]
3132 *) Some browsers ignore cookies that have been merged into a
3133 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
3134 are now unmerged in the http proxy before being sent to the
3135 client. [Graham Leggett]
3137 *) Fix a problem with proxy where each entry of a duplicated
3138 header such as Set-Cookie would overwrite and obliterate the
3139 previous value of the header, resulting in multiple header
3140 values (like cookies) going missing.
3141 [Graham Leggett, Joshua Slive]
3143 *) Add the server-limit and thread-limit values to the scoreboard
3144 for the sake of third-party applications.
3145 [Adam Sussman <myddryn vishnu.vidya.com>]
3147 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
3149 *) OS/390: Get make install to properly copy DSO modules.
3152 *) Win32: Fix bug in mod_status with displaying "Restart Time"
3153 and "Server uptime".
3156 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
3158 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
3160 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
3161 [David MacKenzie <djm pix.net>]
3163 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
3164 [David MacKenzie <djm pix.net>]
3166 *) Fix segfault and display error when SSLMutex file can not be
3167 created. [Adam Sussman <myddryn vishnu.vidya.com>]
3169 *) Add reference counting to mod_mem_cache cache objects to
3170 better manage removing objects from the cache.
3173 *) Change the verbage on the ScoreBoardFile in our default configs.
3174 Also change the default to be commented out (unspecified) so we
3175 get anonymous shared memory by default. [Aaron Bannert]
3177 *) Implement new ScoreBoardFile directive logic. This affects how
3178 we create the scoreboard's shared memory segment. If the directive
3179 is present, a name-based segment is created. If the directive is
3180 not present, first an anonymous segment is created, and if that
3181 fails, a name-based segment is created from a file of the name
3182 DEFAULT_SCOREBOARD. This gives third-party applications the
3183 ability to access our scoreboard. [Aaron Bannert]
3185 *) Allow mod_deflate to work with non-GET requests and properly send
3186 Content-Lengths. [Sander Striker <striker apache.org>]
3188 *) Fix ap_directory_merge() to correctly merge configs when there is
3189 no <Directory /> block. [Justin Erenkrantz, William Rowe]
3191 *) Remove spurious debug messsages that are normal under HTTP
3192 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
3194 *) Fix a bug in mod_cgid that would prevent proper shutdown death
3195 of the cgid process. [Aaron Bannert]
3197 *) Add signal handling back in to the worker MPM for the one_process
3198 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
3200 *) Performance: Reuse per-connection transaction pools in the
3201 worker MPM, rather than destroying and recreating them. [Brian Pane]
3203 *) Remove all signals from the worker MPM's child process. Instead,
3204 the parent uses the Pipe of Death for all communication with the
3205 child processes. [Ryan Bloom]
3207 Changes with Apache 2.0.32
3209 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
3210 default if the directive is not specified. This mirrors older
3211 behavior without changes to the httpd.conf. [William Rowe]
3213 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
3214 the service, mpm and logging code, and bugs in apr_file_open_stderr
3215 and apr_file_dup2 functions. Win2K/XP services have no handles
3216 associated for stdin/out/err, which caused unpredictable behavior
3217 in the prior release. [William Rowe, Bill Stoddard]
3219 *) Win32: simplify the Application Event Log messages, since there isn't
3220 likely to be 'more information in the error log' before an error log
3221 has been opened. [William Rowe]
3223 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
3224 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
3226 *) Win32: apache -k shutdown now behaves like apache -k stop.
3229 *) Fix prefork to not kill the parent if a child hits a resource shortage
3230 on accept(). [Greg Ames]
3232 *) Fix seg faults that occur when what should be the httpd request line
3233 starts with \r\n followed by garbage. [Greg Ames]
3235 *) Allow statically linked support binaries with the new
3236 --enable-static-support flag, and enable this behavior in
3237 the binbuild script. Also add a new --enable-static-htdbm
3238 flag. [Aaron Bannert]
3240 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
3241 do only one stat() call when generating the directory listings.
3244 *) Fix resolve_symlink to save the original symlink name if known.
3247 *) Be a bit more sane with regard to CanonicalNames. If the user has
3248 specified they want to use the CanonicalName, but they have not
3249 configured a port with the ServerName, then use the same port that
3250 the original request used. [Ryan Bloom and Ken Coar]
3252 *) In core_input_filter, check for an empty brigade after
3253 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
3254 client says it will post some data but we get FIN before any
3255 data arrives. [Jeff Trawick]
3257 *) Not being able to bind to the socket is a fatal error. We should
3258 print an error to the console, and return a non-zero status code.
3259 With these changes, all of the Unix MPMs do that correctly.
3262 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
3263 through to CGI scripts. PR 9163
3264 [Brian Reid <breid customlogic.com>,
3265 Zvi Har'El <rl math.technion.ac.il>]
3267 *) binbuild.sh: Make sure that we use the expat from our source
3268 tree so that there aren't any surprises on the target machine.
3271 *) mod_cgid: Add retry logic for when the daemon can't fork fast
3272 enough to keep up with new requests. Start using
3273 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
3274 when we can't talk to the daemon. [Jeff Trawick]
3276 *) apxs: LTFLAGS envvar can override default libtool options. Try
3277 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
3278 the covers. [Jeff Trawick]
3280 *) The Location: response header field, used for external
3281 redirect, *must* be an absoluteURI. The Redirect directive
3282 tested for that, but RedirectMatch didn't -- it would allow
3283 almost anything through. Now it will try to turn an abs_path
3284 into an absoluteURI, but it will correctly varf like Redirect
3285 if the final redirection target isn't an absoluteURI. [Ken Coar]
3287 Changes with Apache 2.0.31
3289 *) Create the scoreboard (in the parent) in a global pool context,
3290 so it survives graceful restarts. This fixes a SEGV during
3291 graceful restarts. [Aaron Bannert]
3293 *) Add a timeout option to the proxy code 'ProxyTimeout'
3296 *) FTP directory listings are now always retrieved in ASCII mode.
3297 The FTP proxy properly escapes URI's and HTML in the generated
3298 listing, and escapes the path components when talking to the FTP
3299 server. It is now possible to browse the root directory by using
3300 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
3301 Also, the last path component may contain wildcard characters
3302 '*' and '?', and if they do, a directory listing is created instead
3303 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
3306 *) Added single-listener unserialized accept support to the
3307 worker MPM [Brian Pane]
3309 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
3310 the incoming host header through to the proxied server
3311 [Geoff <g.russell ieee.org>]
3313 *) New Directive Option for ProxyPass. It now can block a location
3314 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
3316 *) Don't let the default handler try to serve a raw directory. At
3317 best you get gibberish. Much worse things can happen depending
3318 on the OS. [Jeff Trawick]
3320 *) Change the pre_config hook to return a value. Modules can now emit
3321 an error message and then cause the server to quit gracefully during
3322 startup. This required a bump to the MMN. [Aaron Bannert]
3324 *) Fix some unix socket descriptor leaks in the handler side of
3325 mod_cgid (the part that runs in the server process). Whack a
3326 silly "close(-1)" in the handler too. [Jeff Trawick]
3328 *) Change the pre_mpm hook to return a value, so that scoreboard
3329 init errors percolate up to code that knows how to exit
3330 cleanly. This required a bump to the MMN. [Jeff Trawick]
3332 *) Add the socket back to the conn_rec and remove the create_connection
3333 hook. The create_connection hook had a design flaw that did not
3334 allow creating connections based on vhost info. [Bill Stoddard]
3336 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
3337 Resolves the common case of using negotation to resolve the request
3338 /script/foo for /script.cgi/foo. [William Rowe]
3340 *) Added new functions ap_add_(input|output)_filter_handle to
3341 allow modules to bypass the usual filter name lookup when
3342 adding hard-coded filters to a request [Brian Pane]
3344 *) caching should now work on subrequests (still very experimental)
3347 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
3349 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
3352 *) Refactor ap_rgetline so that it does not use an internal brigade.
3353 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
3355 *) Remove mod_auth_db. [Justin Erenkrantz]
3357 *) Do not install unnecessary pcre headers like config.h and internal.h.
3358 [Joe Orton <joe manyfish.co.uk>]
3360 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
3361 (as it does for a normal request). quick_handled sub-requests now work
3362 in mod-include [Ian Holsman]
3364 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
3365 'CONTENT' one, as it needs to run AFTER all content headers
3367 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
3370 *) Split out blocking from the mode in the input filters.
3373 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
3375 *) Cause Win32 to capture all child-worker process errors in
3376 Apache to the main server error log, until the child can
3377 open its own error logs. [William Rowe]
3379 *) HPUX 11.*: Do not kill the child process when accept()
3380 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
3381 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
3383 *) Fix a problem in the parsing of the <Proxy foo> directive.
3386 *) rewrite of mod_ssl input filter for better performance and less
3387 memory usage [Doug MacEachern]
3389 *) allow quick_handler to be run on subrequests. [Ian Holsman]
3391 *) mod_dav now asks its provider to place content directly into the
3392 filter stack when handling a GET request. The mod_dav/provider
3393 API has changed, so providers need to be updated. [Greg Stein]
3395 *) Clear the output socket descriptor in unixd_accept() to make sure
3396 we don't supply a bogus socket to the caller if the accept fails.
3397 This caused problems with the worker MPM, which tried to process
3398 the returned socket if it was non-NULL. [Brian Pane]
3400 *) Move a check for an empty brigade to the start of core input filter
3401 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
3403 *) Add FileETag directive to allow configurable control of what
3404 data are used to form ETag values for file-based URIs. MMN
3405 bumped to 20020111 because of fields added to the end of
3406 the core_dir_config structure. [Ken Coar]
3408 *) Fix a segfault in mod_rewrite's logging code caused by passing the
3409 wrong config to ap_get_remote_host(). [Jeff Trawick]
3411 *) Allow mod_cgid to work from a binary distribution install by
3412 using 755 for the permissions on the log directory instead of
3415 *) Fixed a segfault that happened during graceful shutdown (or when
3416 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
3418 *) Split all Win32 modules [excluding the core components mod_core,
3419 mod_so, mod_win32 and the winnt mpm] into individual loadable
3420 modules, so the administrator may individually disable the former
3421 compiled-in modules by simply commenting out their LoadModule
3422 directives. [William Rowe]
3424 *) Saved Win32 module authors and porters many future headaches, by
3425 duplicating the appropriate .h files such as os.h into the include
3426 directory, including in the build tree. [William Rowe]
3428 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
3429 Use SSL functions/macros instead of directly dereferencing SSL
3430 structures wherever possible.
3431 Add type-casts for the cases where functions return a generic pointer.
3432 Add $SSL/include to configure search path.
3433 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3435 *) Moved several pointers out of the shared Scoreboard so it is
3436 more portable, and will present the vhost name across server
3437 generation restarts. [William Rowe]
3439 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
3442 Changes with Apache 2.0.30
3444 *) Fix the main bug for FreeBSD and threaded MPM's. There are
3445 still issues (see STATUS) but at least the server will now
3446 run without crashing the machine.
3447 [David Reid, Aaron Bannert, Justin Erenkrantz]
3449 *) Fix a typo in mod_deflate's m4 config section.
3450 [albert chin <china thewrittenword.com>]
3452 *) Fix a couple of mod_proxy problems forwarding HTTP connections
3453 and handling CONNECT:
3454 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
3455 (2) Proxy failed to connect when the first IP address returned by
3456 the resolver was unreachable but a secondary IP address was.
3459 *) Fix the module identifer as shown in the docs for various core
3460 modules (e.g., the identifer for mod_log_config was previously
3461 listed as config_log_module). PR #9338
3462 [James Watson <ap2bug sowega.org>]
3464 *) Fix LimitRequestBody directive by placing it in the HTTP
3465 filter. [Justin Erenkrantz]
3467 *) Fix mod_proxy seg fault when the proxied server returns
3468 an HTTP/0.9 response or a bogus status line.
3471 *) Prevent mod_proxy from truncating one character off the
3472 end of the status line returned from the proxied server.
3473 [Adam Sussman, Bill Stoddard]
3475 *) Eliminate loop in ap_proxy_string_read().
3476 [Adam Sussman, Bill Stoddard]
3478 *) Provide $0..$9 results from mod_include regex parsing.
3481 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
3483 *) Introduced the ForceLanguagePriority directive, to prevent
3484 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
3485 when using Multiviews. [William Rowe]
3487 *) Fix a problem which prevented mod_cgid and suexec from working
3488 together reliably [Greg Ames]
3490 *) Remove the call to exit() from within mod_auth_digest's post_config
3491 phase. [Aaron Bannert]
3493 *) Fix a problem in mod_auth_digest that could potentially cause
3494 problems with initialized static data on a system that uses DSOs.
3497 *) Fix a segfault in the worker MPM that could happen during
3498 child process exits. [Brian Pane, Aaron Bannert]
3500 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
3502 *) Fix matching of vhosts by ip address so we find IPv4
3503 vhost address when target address is v4-mapped form of
3504 that address. [Jeff Trawick]
3506 *) More performance tweaks to the BNDM string-search algorithm
3507 used to find "<!--#" tokens in mod_include [Brian Pane]
3509 *) Miscellaneous small performance fixes: optimized away various
3510 string copy operations and removed large temp buffers from
3511 the stack [Brian Pane]
3513 *) Fixed startup segfault that occurred when a VirtualHost
3514 directive had a port but no address [Brian Pane]
3516 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
3518 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
3519 if oslevel < WINNT. This should fix several problems reported
3520 Against 2.0.28 on Windows 98 [Bill Stoddard]
3522 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
3523 to fail. [Bill Stoddard]
3525 *) Change core code to allow an MPM to set hard thread/server
3526 limits at startup. prefork, worker, and perchild MPMs now have
3527 directives to set these limits. [Jeff Trawick]
3529 *) Win32: The async AcceptEx() event should be autoreset upon
3530 successful completion of a wait (WaitForSingleObject). This
3531 eliminates a number of spurious
3532 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
3535 *) Move any load library path environment variables out of
3536 apachectl and into a separate environment variable file which
3537 can be more easily tailored by the admin. The environment
3538 variable file as built by Apache may have additional system-
3539 specific settings. For example, on OS/390 we tailor the heap
3540 settings to allow lots of threads. [Jeff Trawick]
3542 *) Use the new APR pool code to reduce pool-related lock
3543 contention in the worker MPM. [Sander Striker]
3545 *) The POD no longer assumes the child is listening on 127.0.0.1
3546 and now pulls the first hostname in the list of listeners to
3547 perform the dummy connect on. This fixes a bug when the user
3548 had configured the Listen directive for an IP other than
3549 127.0.0.1. This would result in undead children and error
3550 messages such as "Connection refused: connect to listener".
3553 *) The worker MPM now respects the LockFile setting, needed to
3554 avoid locking problems with NFS. [Jeff Trawick]
3556 *) Fix segfault when worker MPM receives SIGHUP.
3557 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
3559 *) Fix bug that could potentially prevent the perchild MPM from
3560 working with more than one vhost/uid. [Aaron Bannert]
3562 *) Change make install and apxs -i processing of DSO modules to
3563 perform special handling on platforms where libtool doesn't install
3564 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
3565 which prevented standard LoadModule statements from working.
3568 *) Whenever mod_so is enabled (not just when there are DSOs for
3569 our modules), do whatever special magic is required for compiling/
3570 loading third-party modules. This allows third-party DSOs to
3571 be used on an AIX build when there were no built-in modules
3572 built as DSOs. (This should help on OS/390 and BeOS as well.)
3575 *) Allow apxs to be used to build DSOs on AIX without requiring the
3576 user to hard-code the list of import files. (This should help
3577 on OS/390 and BeOS as well.) [Jeff Trawick]
3579 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
3580 PR 8563, 8919 [William Rowe]
3582 *) Get binary builds working when libapr and libaprutil are built
3585 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
3586 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
3587 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
3589 *) Fix the handling of SSI directives in which the ">" of the
3590 terminating "-->" is the last byte in a file [Brian Pane]
3592 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
3593 message that we had back in apache-1.3 and still have scattered
3594 throughout our docs. [Aaron Bannert]
3596 *) Prevent the Win32 port from continuing after encountering an
3597 error in the command line args to apache. [William Rowe]
3599 *) On a error in the proxy, make it write a line to the error log
3602 *) Various mod_ssl performance improvements [Doug MacEachern]
3604 Changes with Apache 2.0.29
3606 *) Add buffering in core_output_filter to ensure that long
3607 lists of small buckets don't cause small packet writes.
3608 [Brian Pane, Ryan Bloom]
3610 *) Fix the installation target to make sure that the manual is
3611 installed in the correct location.
3612 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
3613 Gomez Henri <hgomez slib.fr>]
3615 *) Fix the cmd command for mod_include. When we are processing
3616 a cmd command, we do not want to use the r->filename to set
3617 the command name. The command comes from the SSI tag. To do this,
3618 I added a variable to the function that builds the command line
3619 in mod_cgi. This allows the include_cmd function to specify
3620 the command line itself. [Ryan Bloom]
3622 *) Change open_logs hook to return a value, allowing you
3623 to flag a error while opening logs
3624 [Ian Holsman, Doug MacEachern]
3626 *) Change post_config hook to return a value, allowing you
3627 to flag a error post config
3628 [Ian Holsman, Jeff Trawick]
3630 *) Allow SUEXEC_BIN (the path to the suexec binary that is
3631 hard-coded into the server) to be specified to the configure
3632 script by the --with-suexec-bin parameter. [Aaron Bannert]
3634 *) Fix segv in worker MPM following accept on pipe-of-death
3637 *) Add mod_deflate to experimental.
3638 [Ian Holsman, Justin Erenkrantz]
3640 *) Bail out at configure time if an invalid MPM was specified.
3641 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
3643 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
3644 configured [John Sterling <sterling covalent.net>]
3646 *) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>]
3648 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
3650 *) Optimization for the BNDM string-search function in
3651 mod_include. [Brian Pane]
3653 *) Fixed the behavior of the XBitHack directive.
3654 [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
3656 *) The threaded MPM for Unix has been removed. Use the worker
3657 MPM instead. [various]
3659 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
3660 in logging the error from a failed DNS lookup. [Jeff Trawick]
3662 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
3665 *) Get mod_cgid killed when a MPM exits due to a fatal error.
3668 *) Fix a file descriptor leak in mod_include. When we include a
3669 file, we use a sub-request, but we didn't destroy the sub-request
3670 immediately, instead we waited until the original request was
3671 done. This patch closes the sub-request as soon as the data is
3672 done being generated. [Brian Pane <bpane pacbell.net>]
3674 *) Allow modules that add sockets to the ap_listeners list to
3675 define the function that should be used to accept on that
3676 socket. Each MPM can define their own function to use for
3677 the accept function with the MPM_ACCEPT_FUNC macro. This
3678 also abstracts out all of the Unix accept error handling
3679 logic, which has become out of synch across Unix MPMs.
3682 *) Fix a bug which would cause the response headers to be omitted
3683 when sending a negotiated ErrorDocument because the required
3684 filters were attached to the wrong request_rec.
3685 [John Sterling <sterling covalent.net>]
3687 *) Remove commas from the end of the macros that define
3688 directives that are used by MPMs. Prior to this patch,
3689 you would use these macros without commas, which was unlike
3690 the macros for any other directives. Now, the caller provides
3691 the comma rather than the macro providing it. This makes
3692 the macros look more like the rest of the directives.
3693 [Ryan Bloom and Cliff Woolley]
3695 *) Add 'redirect-carefully' environment option to disable sending
3696 redirects under special circumstances. This is helpful for
3697 Microsoft's WebFolders when accessing a directory resource via
3698 DAV methods. [Justin Erenkrantz]
3700 *) Begin to abstract out the underlying transport layer.
3701 The first step is to remove the socket from the conn_rec,
3702 the server now lives in a context that is passed to the
3703 core's input and output filters. This forces us to be very
3704 careful when adding calls that use the socket directly,
3705 because the socket isn't available in most locations.
3708 *) Really reset the MaxClients value in worker and threaded
3709 when the configured value is not a multiple of the number
3710 of threads per child. We said we did previously but we
3711 forgot to. [Jeff Trawick]
3713 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
3715 *) If shared modules are requested and mod_so is not available,
3716 produce a fatal config-time error. [Justin Erenkrantz]
3718 *) Improve http2env's performance by cutting the work it has to
3719 do. [Brian Pane <bpane pacbell.net>]
3721 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
3722 [Brian Pane <bpane pacbell.net>]
3724 Changes with Apache 2.0.28
3726 *) Fix infinite loop in mod_cgid.c.
3727 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
3729 *) When no port is given in a "ServerName host" directive, the
3730 server_rec->port is now set to zero, not 80. That allows for
3731 run-time deduction of the correct server port (depending on
3732 SSL/plain, and depending also on the current setting of
3733 UseCanonicalName). This change makes redirections
3734 work, even with https:// connections. As in Apache-1.3, the
3735 connection's actual port number is never used, only the ServerName
3736 setting or the client's Host: setting. Documentation updated
3737 to reflect the change. [Martin Kraemer]
3739 *) Add a '%{note-name}e' argument to mod-headers, which works in
3740 the same way as mod_log_confg. [Ian Holsman]
3742 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
3743 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
3744 MPMs. [Cliff Woolley]
3746 *) Introduce htdbm, a user management utility for db/dbm authorization
3747 databases. [Mladen Turk <mturk mappingsoft.com>]
3749 *) Optimize usage of strlen and strcat in ap_directory_walk.
3750 [Brian Pane <bpane pacbell.net>]
3752 Changes with Apache 2.0.27
3754 *) Introduce an Apache mod_ssl initial configuration template
3755 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
3757 *) Fixed a memory leak in the getline parsing code that could
3758 be triggered by arbitrarily large header lines. Requests
3759 from the core input filter for single lines are now limited
3760 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
3762 *) Fix a truncation bug in how we print the port on the Via: header.
3763 The routine that prints the Via: header now takes a length for
3764 the port string. [Zvi Har'El <rl math.technion.ac.il>]
3766 *) Some syntax errors in mod_mime_magic's magic file can result
3767 in a 500 error, which previously was unlogged. Now we log the
3768 error. [Jeff Trawick]
3770 *) Add the support/checkgid helper app, which checks the run-time
3771 validity of group identifiers usable in the Group directive.
3774 *) Various --enable-so options have been fixed: --enable-so is
3775 treated as "static"; explicit --enable-so=shared issues an error;
3776 and explicit --enable-so fails with error on systems without
3777 APR_HAS_DSO. [Aaron Bannert]
3779 *) Fix a segfault in the core input filter when the client socket
3780 gets disconnected unexpectedly. [Cliff Woolley]
3782 *) Fix the reporting for child processes that die. This removes
3783 all of the non-portable W* macros from Apache.
3784 [Jeff Trawick and Ryan Bloom]
3786 *) Win32: Track and display "Parent Server Generation:" in
3787 mod_status output. The generation will be bumped at
3788 server graceful restart, when the child process exits
3789 by hitting MaxRequestsPerChild or if the child
3790 process exits abnormally. [Bill Stoddard]
3792 *) Win32: Fix problem where MaxRequestsPerChild directive was
3793 not being picked up in favor of the default. Enable
3794 the parent to start up a new child process immediately upon
3795 the old child starting shutdown.
3798 *) Fix some bungling of the remote port in rfc1413.c so that
3799 IdentityCheck retrieves the proper user id instead of failing
3800 and thus always returning "nobody."
3801 [Dick Streefland <Dick.Streefland xs4all.nl>]
3803 *) Introduced thread saftey for mod_rewrite's internal cache.
3804 [Brian Pane <bpane pacbell.net>]
3806 *) Simplified mod_env's directives to behave as most directives are
3807 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
3808 directive following that UnsetEnv within the same container.
3809 Also provides a runtime startup warning if a PassEnv configured
3810 environment value is undefined. [William Rowe]
3812 *) The worker MPM is now completely ported to APR's new lock API. It
3813 uses native APR types for thread mutexes, cross-process mutexes,
3814 and condition variables. [Aaron Bannert]
3816 *) Sync up documentation to remove all references to the now deprecated
3817 Port directive. [Justin Erenkrantz]
3819 *) Moved all ldap modules from the core to httpd-ldap sub-project
3822 *) Exit when we can't listen on any of the configured ports. This
3823 is the same behavior as 1.3, and it avoids having the MPMs to
3824 deal with bogus ap_listen_rec structures. [Jeff Trawick]
3826 *) Cleanup the proxy code that creates a request to the origin
3827 server. This change adds an optional hook, which allows modules
3828 to gain control while the request is created if the proxy module
3829 is loaded. The purpose of this hook is to allow modules to add
3830 input and/or output filters to the request to the origin. While
3831 I was at it, I made the core use this hook, so that proxy request
3832 creation uses some of the code from the core. This can still be
3833 greatly improved, but this is a good start. [Ryan Bloom]
3835 Changes with Apache 2.0.26
3837 *) Port the MaxClients changes from the worker MPM to the threaded
3840 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
3841 with the new input filtering system. [Justin Erenkrantz]
3843 *) Introduce the MultiviewsMatch directive, to allow the operator
3844 to be flexible in recognizing Handlers and Filters filename
3845 extensions as part of the Multiviews matching logic, strict with
3846 MultiviewsMatch NegotiatedOnly to accept only filename extentions
3847 that designate negotiated parameters, (content type, charset, etc.)
3848 or MultiviewsAll for the 1.3 behavior of matching any files, even
3849 if they have unregistered extensions. [William Rowe]
3851 *) Fixed the configure script to add a LoadModule directive to
3852 the default httpd.conf for any module that was compiled
3853 as a DSO. [Aaron Bannert <aaron clove.org>]
3855 *) rewrite mod_ssl input filtering to work with the new input filtering
3856 system. [Justin Erenkrantz]
3858 *) prefork: Don't segfault when we are able to listen on some but
3859 not all of the configured ports. [Jeff Trawick]
3861 *) Build mod_so even if no core modules are built shared.
3862 [Aaron Bannert <aaron clove.org>]
3864 *) Introduce ap_directory_walk rewrite (with further optimizations
3865 required) to adapt to the ap_process_request_internal() changes.
3866 Optimized so subrequests and redirects now reuse previous section
3867 merges, until we mismatch with the original directory_walk, and
3868 precomputed r->finfo results will cause directory_walk to skip
3869 the most expensive phases of the function. [William Rowe]
3871 *) Allow ApacheMonitor to connect to and control Apache on other
3872 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
3874 *) Remove the Port directive. In it's place, the Listen directive
3875 is now a required directive, which tells Apache what port to
3876 listen on. The ServerName directive has also been extended
3877 to accept an optional port. If the port is specified to the
3878 ServerName, the server will report that port whenever it
3879 reports the port that it is listening on. This change was
3880 made to ease configuration errors that stem from having a Port
3881 directive, and a Listen directive. In that situation, the server
3882 would only listen to the port specified by the Listen command,
3883 which caused a lot of confusion to users. [Ryan Bloom]
3885 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
3886 build, as loadable modules. [William Rowe]
3888 *) Fix --enable-mods-shared processing. If most is specified,
3889 then all modules that can be compiled as shared modules are.
3890 [Aaron Bannert <aaron clove.org>]
3892 *) Update the mime.types file to map video/vnd.mpegurl to mxu
3893 and add commonly used audio/x-mpegurl for m3u extensions.
3894 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
3896 *) Eliminate the depreciated r->content_language, in favor of the array
3897 r->content_languages introduced many years ago. Module authors must
3898 substantially overhaul their modules, so this needs to be upgraded
3899 if the module still relied on backwards-brokeness. [William Rowe]
3901 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
3904 *) Rewrite the input filtering mechanisms to consolidate and reorganize
3905 code. In short, core_input_filter does something now and
3906 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
3908 *) Update the Win32 build to re-absorb mod_proxy and family.
3911 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
3912 current SDK.) [William Rowe]
3914 *) Some style changes to the code that does ProxyErrorOverride. Fixed
3915 config merge behaviour. [Graham Leggett]
3917 *) Allow support programs to be compiled against a static version
3918 of libapr. This allows the smaller support programs to be
3919 relocated. [Aaron Bannert <aaron clove.org>]
3921 *) Update the mime.types file to the registered media types as
3922 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
3924 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
3925 number of clients that can connect at the same time, instead of
3926 specifying the maximum number of child processes.
3927 [Aaron Bannert <aaron clove.org>]
3929 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
3930 be consistent with 1.3. [Justin Erenkrantz]
3932 *) Cache apr_explode_localtime() value for 15 seconds.
3933 [Brian Pane <bpane pacbell.net>]
3935 *) Fix mod_include to not return ETag or Last-Modified headers.
3936 [Ian Holsman <ianh cnet.com>]
3938 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
3940 *) Eliminate the wasteful run-time conversion of method names from strings
3941 to numbers in places where the methods are known at compile time.
3942 [Brian Pane <bpane pacbell.net>]
3944 *) Turn the worker MPM's queue into a LIFO. This may
3945 improve cache-hit performance under some conditions.
3946 [Aaron Bannert <aaron clove.org>]
3948 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
3949 support it. [Justin Erenkrantz]
3951 *) Cleanup the worker MPM. We no longer re-use transaction
3952 pools. This incurs less overhead than shuffling the pools
3953 around so that they can be re-used. Remove one of the
3954 queue's condition variables. We just redefined the API to
3955 state that you can't try to add more stuff than you allocated
3956 segments for. [Aaron Bannert <aaron clove.org>]
3958 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
3960 *) Fixed persistent connections when a request contains a body.
3963 *) mod_dav uses a new API to speak to the backend provider for dead
3964 property management. [Greg Stein]
3966 *) Remove the Win32 script-processing exception from mod_cgi, and
3967 roll build_command_line/build_argv_list into a unified, overrideable
3968 ap_cgi_build_command optional function. [William Rowe]
3970 *) Rewrite find_start_sequence to use a better search algorithm
3971 to find the start tag. [Justin Erenkrantz]
3973 *) Fix a seg fault in mod_include. When we are generating an
3974 internal redirect, we must set r->uri to "", not a bogus
3975 string, and not NULL. [Ryan Bloom]
3977 *) Optimized location_walk, so subrequests, redirects and second passes
3978 now reuse previous section merges on a <Location > by <Location >
3979 basis, until we mismatch with the original location_walk.
3982 *) Back out the 1.45 change to util_script.c. This change made
3983 us set the environment variable REQUEST_URI to the redirected
3984 URI, instead of the originally requested URI.
3985 [Taketo Kabe <kabe sra-tohoku.co.jp>]
3987 *) Make mod_include do lazy evaluation of potentially expensive to
3988 compute variables. [Brian Pane <bpane pacbell.net>]
3990 *) Fix logging of bytes sent for HEAD requests. %b and %B should
3991 log either - or 0, before this patch, they were both logging
3992 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
3994 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
3995 than per character. [Brian Pane <bpane pacbell.net>]
3997 *) Normalize the primary request, redirects and sub-requests to
3998 run the same ap_process_request_internal for consistency in
3999 robustness, behavior and security. [William Rowe]
4001 *) Fix a segfault with mod_include when r->path_info is not set
4002 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
4004 *) Add -X functionality back. This indicates to all MPMs and any other
4005 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
4007 *) Some initial support for the cygwin platform [prefork only].
4008 This is not to be confused with support for the WinNT/Win32
4009 platform, which is the recommended configuration for native
4010 Win32 users. The cygwin platform support is recommended for
4011 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
4013 *) Changed syntax of Set{Input|Output}Filter. The list of filters
4014 must be semicolon delimited (if more than one filter is given.)
4015 The Set{Input|Output}Filter directive now overrides a parent
4016 container's directive (e.g. SetInputFilter in <Directory /web/foo>
4017 will override any SetInputFilter directive in <Directory /web>.)
4018 This new syntax is more consistent with Add{Input|Output}Filter
4019 directives defined in mod_mime. Also cures a bug in prior releases
4020 where the Set{Input|Output}Filter directive would corrupt the
4021 global configuration if the multiple directives were nested.
4024 *) Cured what's ailed mime for quite some time. If an AddSomething
4025 was given in the configuration (Language, Charset, Handler or
4026 Encoding) Apache would set the content type as given by AddType,
4027 but refused to check the mime.types file if AddType wasn't given
4028 for that specific extension. Setting the AddHandler for .html
4029 without setting the AddType text/html html would cause Apache to
4030 use the default content type. [William Rowe]
4032 *) Added some bulletproofing to memory allocation in the LDAP cache
4033 code. [Graham Leggett]
4035 Changes with Apache 2.0.25
4037 *) Move the installed /manual directory out of the /htdocs/ tree, so
4038 that it can be kept more independently from the remaining document
4039 root. The "Alias /manual ..." already allowed for easy projection
4040 into existing private document trees. [Martin Kraemer]
4042 *) Add specified user attributes to the environment when using
4043 mod_auth_ldap. This allows you to use mod_include to embed specified
4044 user attributes in a page like so:
4045 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
4048 *) Fix a performance problem with the worker MPM. We now create
4049 transaction pools once, and re-use them for each connection.
4050 [Aaron Bannert <aaron clove.org>]
4052 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
4053 of a 'handler' or 'filter', so that any filename extension that does
4054 not contribute to the negotiated metadata can't be served without
4055 an explicit request. E.g., if the .Z extension is associated with
4056 an unzip filter, the user request somefile.Z.html, mod_negotiation
4057 won't serve it. It can serve somefile.Z.html when somefile.Z is
4058 requested, since the .Z extension is explictly requested, if the
4059 .html extension is associated with ContentType text/html.
4062 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
4063 and corresponding AddOutputFilter syntax, to insert one or more
4064 filters by mod_mime filename extension processing.
4067 *) Fix a growing connection pool in core_output_filter() for
4068 keepalive requests. [Jeff Trawick]
4070 *) Moved split_and_pass_pretag_buckets back to being a
4071 macro at Ryans's request. Removed the return from it
4072 by setting and returning a return code instead. Updated
4073 the code to check the return code from the macro and
4074 do the right thing. [Paul J. Reder]
4076 *) Fix a segfault when a numeric value was received for Host:.
4079 *) Add a function ap_remove_input_filter. This is to match
4080 up with ap_remove_output_filter. [Ryan Bloom]
4082 *) Clean up location_walk, so that this step performs a minimum
4083 amount of redundant effort (it must be run twice, but it will no
4084 longer reparse all <Location > blocks when the request uri
4085 hadn't changed.) [William Rowe]
4087 *) Eliminate proxy: (and all other 'special') processing from the
4088 ap_directory_walk() phase. Modules that want to use special
4089 walk logic should refer to the mod_proxy map_to_location example,
4090 with it's proxy_walk and proxysection implementation. This makes
4091 either directory_walk flavor much more legible, since that phase
4092 only runs against real <Directory > blocks.
4095 *) SECURITY: Fix a security problem in mod_include which would allow
4096 an SSI document to be passed to the client unparsed.
4097 [Cliff Woolley, Brian Pane]
4099 *) Introduce the map_to_storage hook, which allows modules to bypass
4100 the directory_walk and file_walk for non-file requests. TRACE
4101 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
4102 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
4105 *) Add the ability for mod_include to add the INCLUDES filter
4106 if the file is configured for the server-parsed handler.
4107 This makes the configuration for .shtml files much easier
4108 to understand, and allows mod_include to honor Apache 1.3
4109 config files. Based on Doug MacEachern's patch to PHP
4110 to do the same thing. [Ryan Bloom]
4112 *) force OpenSSL to ignore process local-caching and to always
4113 get/set/delete sessions using mod_ssl's callbacks
4114 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
4115 Geoff Thorpe <geoff geoffthorpe.net>]
4117 *) Make the worker MPM shutdown and restart cleanly. This also
4118 cleans up some race conditions, and gets the worker using
4119 pools more cleanly. [Aaron Bannert <aaron clove.org>]
4121 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
4123 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4125 *) Fix for mod_include. Ryan's patch to check error
4126 codes put a return in the wrong place. Also, the
4127 include handler return code wasn't being checked.
4128 I don't like macros with returns, so I converted
4129 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
4130 [Paul J. Reder <rederpj raleigh.ibm.com>]
4132 *) fix segv in mod_mime if no AddTypes are configured
4133 [John Sterling <sterling covalent.net>]
4135 *) Enable ssl client authentication at SSL_accept time
4136 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4138 *) Fix a segfault in mod_include when the original request has no
4139 associated filename (e.g., we're filtering the error document for
4140 a bad URI). [Jeff Trawick]
4142 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
4144 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
4145 of httpd is started and shuts down due to socket conflict. Moving the
4146 call to ap_log_pid solves the problem.
4148 *) Changed the late-1.3 log_config substitution %c to %X, to log the
4149 status of the closed connection, as it conflicts with the far more
4150 common, historical ssl logging directive %...{var}c. [William Rowe]
4152 *) Added the common error/ tree to the build/install targets
4153 (similar to the common icons/ tree) for the multi-language error
4154 messages that Lars committed earlier. [William Rowe]
4156 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
4158 *) Added a default commented-out mod_ldap and mod_auth_ldap
4159 configuration to httpd-std.conf and httpd-win.conf
4162 *) Added documentation for mod_ldap and mod_auth_ldap.
4165 *) Enabled negative caching on attribute comparisons in the LDAP cache.
4166 Fixed a problem where the default cache TTL was set in milliseconds
4167 not microseconds causing the cache to time out almost immediately.
4170 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
4171 module code to follow APR. [Graham Leggett]
4173 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
4174 cleaned up when the connection pool pool is cleaned up.
4177 *) Fix a minor issue with Jeff Trawick's mod_include
4178 patch. Without this patch, the code will just allocate
4179 more bytes in get_combined_directive than are needed.
4182 *) Added the LDAP authentication module mod_auth_ldap.
4183 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
4185 *) Added the LDAP cache and connection pooling module mod_ldap.
4186 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
4188 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
4189 by allowing a module to disable itself if its prerequisites are not
4190 met. [Justin Erenkrantz]
4192 Changes with Apache 2.0.24
4194 *) Fix a couple of issues in mod_include when the tag appeared at
4195 offsets near 8192 in the file being parsed. [Jeff Trawick]
4197 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
4198 reached. [Jeff Trawick]
4200 *) Numerous improvements to the Win32 build system. Introduced command line
4201 builds without requiring .mak files for MSVC 6.0 and later versions.
4202 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
4205 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
4206 reporting of uninstalled services and other error conditions, and changed the
4207 default service name to Apache2. [William Rowe]
4209 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
4210 compatibility with existing Apache 1.3 Win32 Apache management utilites.
4211 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
4213 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
4214 [William Rowe, Greg Ames]
4216 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
4217 and RemoveCharset directives. [William Rowe]
4219 *) The Unix MPMs other than perchild now allow child server
4220 processes to use the accept mutex when starting as root and
4221 using SysV sems for the accept mutex. Previously, this
4222 combination would lead to fatal errors in the child server
4223 processes. perchild can't use SysV sems because of security
4224 issues. [Jeff Trawick, Greg Ames]
4226 *) Added Win32 revision stamp resources to all http binaries
4227 (including modules/ and support/ tools.) PR7322 [William Rowe]
4229 *) Fix ap_rvprintf to support more than 4K of data at one time.
4230 [Cody Sherr <csherr covalent.net>]
4232 *) We have always used the obsolete/deprecated Netscape syntax
4233 for our tracking cookies; now the CookieStyle directive
4234 allows the Webmaster to choose the Netscape, RFC2109, or
4235 RFC2965 format. The new CookieDomain directive allows the
4236 setting of the cookie's Domain= attribute, too. PR #s 5006,
4237 5023, 5920, 6140 [Ken Coar]
4239 *) Tweak server/Makefile so that the rules for generating exports.c
4240 are compatible with make utilities which don't expand wildcards
4241 in a dependency list (e.g., OS/390 make, certain levels of GNU
4242 make). [Jeff Trawick]
4244 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
4246 *) Begin to sanitize the MPM configuration directives. Now, all
4247 MPMs use the same functions for all common MPM directives. This
4248 should make it easier to catch all bugs in these directives once.
4249 [Cody Sherr <csherr covalent.net>]
4251 *) Close a major resource leak. Every time we had issued a
4252 graceful restart, we leaked a socket descriptor.
4255 *) Fix a problem with the new method code. We need to cast
4256 the 1 to an apr_int64_t or it will be treated as a 32-bit
4257 integer, and it will wrap after being shifted 32 times.
4258 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
4260 *) Fix a bug in mod_expires. Previous to this patch, if you
4261 told mod_expires to add 604800 seconds to the last-modified
4262 time, it actually added 604800 usec's to the last-modified time,
4263 so that when looking at the response it looked like nothing
4264 had been done. The root of the problem was that we always compute
4265 time in usec's, but we ask users to input sec's. This means we
4266 need to convert to usec's before using those values.
4269 *) The worker MPM now handles shutdown and restart requests. It
4270 definitely isn't perfect, but we do stop the servers correctly.
4271 The biggest problem right now is that SIGHUP causes the server to
4272 just die. [Ryan Bloom]
4274 Changes with Apache 2.0.23
4276 *) Use the prefork MPM by default on Unix. [various]
4278 *) Added a systray icon monitor application for Win32.
4279 [Mladen Turk <mturk mappingsoft.com>]
4281 *) mod_rewrite: Fix the line ending on some non-Unix systems for
4282 messages written to the rewrite log.
4283 [Richard Labennett <rlabenn us.ibm.com>]
4285 *) All mod_autoindex query parsing is now quietly quashed with the
4286 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
4287 still drops the column sort <a href>'s for the column headers, but
4288 IgnoreClient is required to ignore these Query options entirely.
4291 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
4292 to allow the client to select plain, FancyIndexing or HTMLTable
4293 formatting, V=[0|1] to inhibit or enable version sorting, and
4294 P=pattern to return only specific files. The old Query Arguments
4295 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
4296 as before), and O=A|D for ordering ascending or descending.
4299 *) Fixed an error in mod_include's directive parsing routines which
4300 caused #if, #elif, and #else expressions containing backslashes
4301 to be improperly evaluated. [Cliff Woolley]
4303 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
4304 drop the icon column, SuppressRules to drop the <hr> elements,
4305 and HTMLTable to create rudimentary HTML table listings (implies
4306 FancyIndexing). [William Rowe]
4308 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
4309 from Apache 1.3.15. This is needed for two reasons, first, given
4310 multiple machines within a server farm, ETags and Last-Modified
4311 stamps won't correspond from machine to machine, and second, many
4312 Unixes don't capture changes to the date or time stamp of existing
4313 files, since these don't modify the dirent itself. [William Rowe]
4315 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
4316 and DirectoryWidth options from Apache 1.3.10.
4317 [William Rowe, Ken Coar]
4319 *) Eliminated FancyIndexing directive, deprecated early in Apache
4320 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
4322 *) mod_autoindex now excludes any file names that would result in
4323 an error, other than a success or redirect. Also optimized
4324 the parent directory, always included except in the URI '/'.
4327 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
4328 negotiated index pages, and prevent the server from defaulting
4329 to an autoindex of the directory. mod_negotiation will now die
4330 with a 500 Internal Error if it could match some filenames
4331 (e.g. for mod_dir) but none can be served. mod_negotation now
4332 refuses to serve any file with an extention that mod_mime doesn't
4333 recognize, and wasn't part of the request. [William Rowe]
4335 *) Eliminate mod_cgi's handling of .exe files without the .exe file
4336 extension. This is already handled by multiviews, if the admin
4337 wishes to AddHandler .exe or define a content type handler and
4338 associate .exe files with that content type. Multiviews must be
4339 enabled to allow these to be served. [William Rowe]
4341 *) Speed up the server's response to a spike in incoming workload
4342 or restarts by assigning empty scoreboard slots to new processes
4343 when they are available. [Greg Ames]
4345 *) Add a handler to mod_includes.c. This handler is designed to
4346 implement the XbitHack directive. This can't be done with a
4347 fixup, because we need to check the content-type, which is
4348 only available in the handler phase. [Ryan Bloom]
4350 *) Make the includes filter check return codes from filters lower in
4351 the filter chain. If a lower level filter returns an error, then
4352 the request needs to stop immediately. This allows mod_include to
4353 stop parsing data once a lower filter recognizes an error.
4356 *) Add the ability to extend the methods that Apache understands
4357 and have those methods <limit>able in the httpd.conf. It uses
4358 the same bit mask/shifted offset as the original HTTP methods
4359 such as M_GET or M_POST, but expands the total bits from an int to
4360 an ap_int64_t to handle more bits for new request methods than
4361 an int provides. [Cody Sherr <csherr covalent.net>]
4363 *) Fix broken mod_mime behavior in merging its arguments. Possible
4364 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
4366 *) Solve many mod_ssl porting issues (too many to detail) with
4367 help from the whole team, but most notably [Ralf S. Engelschall,
4368 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
4369 Doug MacEachern, William Rowe, Cliff Woolley]
4371 *) More stall fixes for the threaded & worker mpm's.
4372 Make mod_status output more accurate. Don't
4373 count workers in processes which aren't actively
4374 serving requests. [Greg Ames]
4376 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
4378 *) Add a single listener/multiple worker MPM. This MPM is
4379 definately not fully correct, but it allows us to solve many
4380 of the problems that exist in the threaded MPM. This is a
4381 modified version of the threaded MPM. [Ryan Bloom]
4383 *) Improve content generation throughout Apache, providing closer
4384 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
4385 Transitional specifications. [William Rowe]
4387 Changes with Apache 2.0.22
4389 *) Fix a problem where the threaded MPM stalls after restarts or
4390 segfaults. Also prevent multiple active processes from using
4391 the same scoreboard slot. [Greg Ames]
4393 *) Apache/Win32 now fills in the service description with Apache's
4394 server version string, including loaded and advertised modules.
4397 *) Improved support for the Win32 build, to recover gracefully from
4398 missing apr or apr-util directories or the awk interpreter,
4399 create the proper cgi-bin examples, including a test-cgi.bat, and
4400 fix the perl shebang line for printenv.pl, when installing from
4401 the build environment. [William Rowe]
4403 *) Fix a segfault in threaded.c caused by passing uninitialized
4404 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
4406 *) Use new APR number conversion functions to reduce CPU consumption
4407 when setting the content length, and in mod_log_config.
4410 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
4411 where HEAD response headers were being repeated twice for
4412 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
4413 problem in the http_header filter was exposed by the recent rewrite
4414 of the content_length filter. [Taketo Kabe, Bill Stoddard]
4416 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
4417 restarts. A garbage pointer to a vhost's server_rec from the
4418 previous generation was being left around under certain
4419 conditions. [Greg Ames]
4421 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
4422 used to appear as '(none', without the closing paren.
4423 [Günter Knauf <eflash gmx.net>]
4425 *) Improve the exports generating awk script. In the past, we had
4426 work around problems in the awk script by avoiding some #if and
4427 #ifdefs. This has bitten us many times in generating the exports.c
4428 file. This improvement allows corrects the header file parsing.
4429 [Sander Striker <striker apache.org>]
4431 Changes with Apache 2.0.21
4433 *) Resolve the Win32 htpasswd bug, where a file that existed would be
4434 overwritten, regardless of the -c flag.
4435 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
4437 *) Introduce connection sub-pools into ab. Truncating the lifetime
4438 of these allocations means that ab no longer perpetually grows
4439 its working set, running out of memory on large request attempts.
4442 *) Make scoreboard creation a hook. This allows management
4443 modules to have access to the scoreboard at the time that it is
4444 created, and at every restart request.
4445 [Cody Sherr <csherr covalent.net>]
4447 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
4448 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
4449 daemon index actually used in the scoreboard. I also
4450 updated the pertinent calls. [Paul J. Reder]
4452 *) Win32: Prevent listening sockets from being inherited by
4453 the Apache child process, CGI scripts, rotatelog process
4454 etc. If the Apache child process segfaults, any processes
4455 that the child started are not reaped. Prior to this fix,
4456 these processes inherited the listening sockets which sometimes
4457 prevented the restarted Apache child process from accepting
4458 connections (ie, the server would hang).
4461 *) Provide vhost and request strings when ExtendedStatus is on.
4464 *) Fix some issues with the pod and prefork: check the pod *after*
4465 processing a connection so that a server processing a time-
4466 consuming request bails out as soon as practical; when the
4467 parent process wakes up a server process via connect(), use an
4468 APR timeout on the connect() so that we don't hang for a long
4469 time if there aren't server processes around to do accept().
4470 [Jeff Trawick, Greg Ames]
4472 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
4473 spends a lot of time in apr_table_get calls. Using the default
4474 httpd.conf, the tables for languages and charsets are somewhat
4475 large, so the time spent scanning them on each request is
4476 significant. Replacing the tables with hash tables provides
4477 a nice speedup. [Brian Pane <bpane pacbell.net>]
4479 *) Add two functions to allow modules to access random parts of the
4480 scoreboard. This allows modules compiled for one MPM to access the
4481 scoreboard, even if it the server was compiled for another MPM.
4482 [Harrie Hazewinkel <harrie covalent.net>]
4484 Changes with Apache 2.0.20
4486 *) Fix problem in content-length filter where the filter would
4487 buffer all the output from a CGI before sending any bytes
4488 down the filter stack to the network. This problem would cause
4489 significant memory consumption if the CGIs generated
4490 lots of bytes. [Bill Stoddard]
4492 *) Get non-blocking CGI pipe reads working with the bucket brigades.
4495 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
4498 *) Fix a bug in the threaded MPM that would cause it to kill off all
4499 workers immediately after starting if the number of workers started
4500 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
4502 Changes with Apache 2.0.19
4504 *) Fix problem with threaded MPM. The problem was that if each child
4505 process was busy serving a single long-lived request and the server
4506 was sent a graceful restart signal, the server would stop serving
4507 requests. This would happen because each child process would wait to
4508 die until the last thread was done, and the parent wouldn't spawn any
4509 new children until a process died. Now, the parent looks at the fact
4510 that the children are dying gracefully, and starts new children.
4511 Those new children only start enough threads to compliment the number
4512 of threads in the other child process that shares the same spot in
4513 the scoreboard. In this way, we make sure to never go over
4514 MaxClients. [Ryan Bloom]
4516 *) modified mod_negotiation and mod_autoindex to speed up by almost a
4517 factor of two on apr_dir_read()-enhanced platforms, such as Win32
4518 and OS2, by calling ap_sub_request_lookup_dirent() with the results
4519 already provided by apr_dir_read(). [William Rowe]
4521 *) mod_file_cache is now more robust to filtering and serves requests
4522 slightly more efficiently. [Cliff Woolley]
4524 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
4525 Module was calling ap_rwrite() followed by ap_rflush() but the
4526 served content was not being displayed in the browser. Inspection
4527 of the output stream revealed that the first data chunk was
4528 missing the trailing CRLF required by the RFC. [Bill Stoddard]
4530 *) apxs no longer generates ap_send_http_header() in the example handler
4532 *) Fix an ab problem which could cause a divide-by-zero exception
4533 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
4534 [Ian Holsman <ianh cnet.com>]
4536 *) Solve case-insensitive platforms' confusion about negotiated
4537 filenames, allowing files of differnt case to match in choosing
4538 the document to serve. [William Rowe]
4540 *) Fix brokenness when ThreadsPerChild is higher than the built-in
4541 limit. We left ap_threads_per_child at the higher value which
4542 led to segfaults when doing certain scoreboard operations.
4545 *) Fix seg faults and/or missing output from mod_include. The
4546 default_handler was using the subrequest pool for files and
4547 MMAPs, even though the associated APR structures typically
4548 live longer than the subrequest. [Greg Ames]
4550 *) Extend mod_setenvif to support specifying regular expressions
4551 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
4552 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
4553 will cause HAVE_TS to be set if any of the request headers begins
4554 with "TS" and has a value that begins with any character in the
4555 set [a-z]. [Bill Stoddard]
4557 *) httpd children now re-bind themselves to a random CPU on
4558 multiprocessor systems on AIX via bindprocessor() in 2.0.
4559 [Victor J. Orlikowski]
4561 *) Fix htdigest. It would go into a loop in getline when adding
4562 a second user. [Bill Stoddard]
4564 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
4566 *) Automatically generate httpd.exp for AIX.
4567 DSOs now work again on AIX in 2.0
4568 [Victor J. Orlikowski]
4570 *) Add a new request hook, error_log. This phase allows modules
4571 to act on the error log string _after_ it has been written
4572 to the error log. The goal for this hook is to allow monitoring
4573 modules to send the error string to the monitoring agent.
4576 *) Modify mod_echo to make it use filters for input and output.
4577 [Ryan Morgan <rmorgan covalent.net>]
4579 *) Extend mod_headers to support conditional driven Header
4580 add, append and set. Use SetEnvIf to set an envar and conditionally
4581 add/append/set headers based on this envar thusly:
4583 SetEnvIf TSMyHeader value HAVE_TSMyHeader
4584 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
4586 If the request contains header "TSMyHeader: value" then header
4587 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
4590 *) Extend mod_headers to support using format specifiers on Header
4591 add, append and set header values. Two format specifiers are supported:
4593 %t - reports, in UTC microseconds since the epoch, when the
4594 request was received.
4596 %D - reports the time, in microseconds, between when the request was
4597 received and the response sent.
4600 Header add MyHeader "This request served in %D microseconds. %t"
4602 results in a header being added to the response that looks like this:
4604 MyHeader: This request served in D=5438 microseconds. t=991424704447256
4608 *) Fix reset_filter(). We need to be careful how we remove filters.
4609 If we set r->output_filters to NULL, we also have to reset the
4610 connection's filters. [John Sterling]
4612 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
4614 *) Add a check to ap_die() to make sure the filter stack is sane and
4615 contains the correct basic filters when an error occurs. This fixes
4616 a problem where headers are not being sent on error. [John Sterling]
4618 *) New Header directive 'echo' option. "Header echo regex" will
4619 cause any headers received on the request that match regex to be
4620 echoed to (included in) the response headers.
4623 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
4624 This prevented the inclusion of apr_compat.h. PR #7773
4625 [Oleg Broytmann <phd phd.pp.ru>]
4627 *) Moved util_uri to the apr-util library. This required a bunch of
4628 apr_name changes for the uri utility functions. [Justin Erenkrantz]
4630 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
4631 insert_filter phase so that other filters are not bypassed by default.
4634 *) Reimplement mod_headers as an output filter. mod_headers can now
4635 add custom headers to inbound requests using the RequestHeader directive
4636 and to responses using the same old Header directive. [Graham Leggett]
4638 Changes with Apache 2.0.18
4640 *) Fix command-line processing so that if a bad argument is specified
4641 Apache will exit. [Jeff Trawick]
4643 *) Change the make targets and rules to be consistent in all of the
4644 Apache-owned source trees. [Roy Fielding]
4646 *) Fix processing of the TRACE method. Previously we passed bogus
4647 parms to form_header_field() and it overlaid some vhost structures,
4648 resulting in a segfault in check_hostalias().
4649 [Greg Ames, Jeff Trawick]
4651 *) Win32: Add support for reliable piped logs. If the logging process
4652 goes down, Apache will automatically restart it. This function has
4653 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
4656 *) Do not start piped log processes during the config file
4657 preflight. This change also circumvents a problem on
4658 Windows where the rotatelog processes created during preflight
4659 was not getting cleaned up properly.
4662 *) add "Request Phase Participation" info to mod_info
4665 *) Make first phase changes to the scoreboard data structures in
4666 preparation for the rewriting of the scoreboard per my posted
4667 design notes. [Paul J. Reder]
4669 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
4670 and apr-util, allow it to be overridden by the configure command-line
4671 (default="--silent") and introduce LT_LDFLAGS to replace what we were
4672 formerly abusing as LTFLAGS. [Roy Fielding]
4674 *) Clean up the reporting of incorrect closing container tags.
4675 [Barrie Slaymaker <barries slaysys.com>]
4677 *) Simplify the configure process by moving all libtool stuff to APR
4678 and moving hints.m4 inline. [Roy Fielding]
4680 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
4681 of functions used by mod_proxy for export in the DLL
4682 [Ian Holsman <IanH cnet.com>]
4684 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
4685 request body from its stdin but no reqest body is being written to
4686 the cgi. [Jeff Trawick]
4688 *) mod_log_config: %c connection status incorrectly logged
4689 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
4692 *) Get mod_cern_meta working under Windows
4695 *) Create Files, and thus MMAPs, out of the request pool, not the
4696 connection pool. This solves a small resource leak that had us
4697 not closing files until a connection was closed. In order to do
4698 this, at the end of the core_output_filter, we loop through the
4699 brigade and convert any data we have into a single HEAP bucket
4700 that we know will survive clearing the request_rec.
4701 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
4704 *) Completely revamp configure so that it preserves the standard make
4705 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
4706 the configure additions to EXTRA_* variables. Also, allow the user
4707 to specify NOTEST_* values for all of the above, which eliminates the
4708 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
4709 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
4710 avoid pointless duplications. Fix the order in which flags are given
4711 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
4712 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
4713 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
4714 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
4716 *) Get mod_tls to compile/work better on Windows. PR #7612
4717 [Bernhard Schrenk <b.schrenk improx.com>]
4719 *) Fix shutdown/restart hangs in the threaded MPM.
4720 [Jeff Trawick, Greg Ames, Ryan Bloom]
4722 *) Removed the keptalive boolean from conn_rec because it is now only
4723 used by a single routine and can be replaced by a local variable.
4724 [Greg Stein, Ryan Bloom, Roy Fielding]
4726 *) Patch prefork to put enough of the signal processing back in so that
4727 signals are all handled properly now. The previous patch fixed the
4728 deadlock race condition, but broke the user directed signal handling.
4729 This fixes it to work the way it did before my previous prefork patch
4730 (primarily, SIGTERM is now working).
4732 *) Change how input filters decide how much data is returned to the
4733 higher filter. We used to use a field in the conn_rec, with this
4734 change, we use an argument to ap_get_brigade to determine how much
4735 data is retrieved. [Ryan Bloom]
4737 *) Fix seg fault at start-up introduced by Ryan's change to enable
4738 modules to specify their own logging tags. mod_log_config
4739 registers an optional function, ap_register_log_handler().
4740 ap_register_log_handler() was being called by http_core before
4741 the directive hash table was created. This patch creates the
4742 directive hash table before ap_register_log_handler() is
4743 registered as an optional function.
4744 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4746 *) Add ap_set_int_slot() function
4747 [John K. Sterling <sterling covalent.net>]
4749 *) Under certain circumstances, Apache did not supply the
4750 right response headers when requiring authentication.
4751 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
4752 (This is a port of the change that went into Apache 1.3.19.)
4754 *) Allow modules to specify their own logging tags. This basically
4755 allows a module to tell mod_log_config that when %x is encountered
4756 a specific function should be called. Currently, x can be any single
4757 character. It may be more useful to make this a string at some point.
4760 Changes with Apache 2.0.17
4762 *) If a higher-level filter handles the byterange aspects of a
4763 request, then the byterange filter should not try to redo the
4764 work. The most common case of this happening, is a byterange
4765 request going through the proxy, and the origin server handles
4766 the byterange request. The proxy should ignore it.
4767 [Graham Leggett <minfrin sharp.fm>]
4769 *) Changed the threaded mpm to have child_main join to each of the
4770 worker threads to make sure the kids are all gone before child_main
4771 exits after a signal (cleanup from perform_idle_server_maintenance).
4772 This is an extension of Ryans recent commit to make the child_main
4775 *) Add more options to the ap_mpm_query function. This also allows MPMs to
4776 report if their threads are dynamic or static. Finally, this also
4777 implements a new API, ap_show_mpm, which returns the MPM that was
4778 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
4780 *) Do not install the binaries from the support directory twice.
4781 [jun-ichiro hagino <itojun iijlab.net>]
4783 *) The ap_f* functions should flush data to the filter that is passed
4784 in, not the filter after the one passed in.
4785 [Ryan Morgan <rmorgan covalent.net>]
4787 *) Make ab work again by changing its native types to apr types and formats.
4788 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4790 *) Move the byterange filter and all of the supporting functions back
4791 to the HTTP module. The byterange filter turned out to be very
4792 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
4794 *) Make clean, distclean, and extraclean consistently according to the
4795 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4797 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
4798 This may have been causing problems stopping processes in the threaded
4801 *) Fix content-length in mod_negotiation to a long int representation.
4804 *) Remove BindAddress from the default config file.
4805 [<giles nemeton.com.au>]
4807 *) Allow module authors to add a module to their Apache build using
4808 --with-module, without re-running buildconf. The syntax is:
4809 --with-module=module_type:/path/to/module.c
4810 The configure script will copy the module.c file to
4811 modules/module_type, and it will be added to the relevant Makefiles.
4812 currently, this only works for static modules. [Ryan Bloom]
4814 *) Changes required to make prefork clean up idle children properly.
4815 There was a window during which a starting worker deadlocks when
4816 an idle cleanup arrives before it completes init. Apache then keeps
4817 trying to cleanup the same deadlocked worker forever (until higher
4818 pids come along, but it still will never reduce below the deadlocked
4819 pid). Thus the number of children would not reduce to the correct
4820 idle level. [Paul J. Reder]
4822 Changes with Apache 2.0.16
4824 *) Change the default installation directory to /usr/local/apache2,
4825 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
4827 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
4830 *) Get MaxRequestsPerChild working with the Windows MPM.
4833 *) Make generic hooks to work, with mod_generic_hook_import/export
4834 experimental modules. [Ben Laurie, Will Rowe]
4836 *) Fix segfaults for configuration file syntax errors such as
4837 "<Directory>" followed by "</Directory" and
4838 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
4840 *) Cleanup the --enable-layout option of configure. This makes
4841 us use a consistent location for the config.layout file, and it
4842 makes configure more portable.
4843 [jun-ichiro hagino <itojun iijlab.net>]
4845 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
4846 csv/gnuplot format, rudimentary ssl support and various other tweaks
4847 to make results more true to what is measured. The upshot of this it
4848 turns out that 'ab' has often underreported the true performance of
4849 apache. Often by a order of magnitude :-) See talk/paper of Sander
4850 Temme at April ApacheCon 2001 for details.
4851 [Dirk-Willem van Gulik]
4853 *) Clean up mod_cgid's temporary request pool. Besides fixing a
4854 storage leak this ensures that some unnecessary pipes are closed.
4857 *) Performance: Add quick_handler hook. This hook is called at the
4858 very beginning of the request processing before location_walk,
4859 translate_name, etc. This hook is useful for URI keyed content
4860 caches like Mike Abbott's Quick Shortcut Cache.
4863 *) top_module global variable renamed to ap_top_module [Perl]
4865 *) Move ap_set_last_modified to the core. This is a potentially
4866 controversial change, because this is kind of HTTP specific. However
4867 many protocols should be able to take advantage of this kind of
4868 information. I expect that headers will need one more layer of
4869 indirection for multi-protocol work, but this is a small step in
4870 the right direction. [Ryan Bloom]
4872 *) Enable mod_status by default. This matches what Apache 1.3 does.
4875 *) Add a ScriptSock directive to the default config file. This is
4876 only enabled when mod_cgid is used.
4877 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4879 Changes with Apache 2.0.15
4881 *) Untangled the buildconf script and eliminated the need for build's
4882 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
4883 libtool muck that is now under srclib/apr/build. [Roy Fielding]
4885 *) Win32: Don't accept more connections than we have worker threads
4889 *) Fix bug in the Unix threaded.c MPM that allowed child processes
4890 to fork() new child processes.
4893 *) SECURITY: Fix a major security problem with double-reverse lookup
4894 checking. Previously, a client connecting over IPv4 would not be
4895 matched properly when the server had an IPv6 listening socket.
4896 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
4898 *) Change the way the beos MPM handles polling to allow it to stop and
4899 restart. Problem was the sockets being polled were being reset by
4900 the select call, so once it had accepted a connection it was no
4901 longer listening on the UDP socket we use for shutdown instructions.
4902 APR needs to be altered, patch on it's way. [David Reid]
4904 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
4905 on error exit from ap_getline(). Some other code got upset because
4906 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
4908 *) Handle ap_discard_request_body() being called more than once.
4909 [Greg Ames, Jeff Trawick]
4911 *) Get rid of an inadvertent close of file descriptor 2 in
4912 mod_mime_magic. [Greg Ames, Jeff Trawick]
4914 *) Add a hook, create_request. This hook allows modules to modify
4915 a request while it is being created. This hook is called for all
4916 request_rec's, main request, sub request, and internal redirect.
4917 When this hook is called, the r->main, r->prev, r->next
4918 pointers have been set, so modules can determine what kind of
4919 request this is. [Ryan Bloom]
4921 *) Cleanup the build process a bit more. The Apache configure
4922 script no longer creates its own helper scripts, it just
4924 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4926 *) Stop the forced downgrade of the connection to HTTP/1.0 for
4927 proxy requests. [Graham Leggett]
4929 *) Avoid using sscanf to determine the HTTP protocol number in
4930 the common case because sscanf is a performance hog. From
4931 Mike Abbot's Accelerating Apache patch number 6.
4932 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
4934 *) SECURITY: Fix a security exposure in mod_access. Previously when
4935 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
4936 were not evaluated properly (PR #7407). Also, add the ability to
4937 specify IPv6 address strings with optional prefix length on Allow
4938 and Deny. [Jeff Trawick]
4940 *) Enhance rotatelogs so that a UTC offset can be specified, and
4941 the logfile name can be formatted using strftime(3). (Brought
4942 forward from 1.3.) [Ken Coar]
4944 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
4945 DuplicateHandle on an IOCompletionPort (a practice which
4946 MS "discourages"). The new model does not rely on associating
4947 the completion port with the listening sockets, thus the
4948 completion port can be completely managed within the child
4949 process. A dedicated thread accepts connections off the network,
4950 then calls PostQueuedCompletionStatus() to wake up worker
4951 threads blocked on the completion port.
4954 *) Bring forward the --suexec-umask option which allows the
4955 builder to preset the umask for suexec processes. [Ken Coar]
4957 *) Add a -V flag to suexec, which causes it to display the
4958 compile-time settings with which it was built. (Only
4959 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
4961 *) Mod_include should always unset the content-length if the file is
4962 going to be passed through send_parsed_content. There is no to
4963 determine if the content will change before actually scanning the
4964 entire content. It is far safer to just remove the C-L as long
4965 as we are scanning it. [Ryan Bloom]
4967 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
4968 request and not Proxy-Authenticate.
4969 [Graham Leggett <minfrin sharp.fm>]
4971 Changes with Apache 2.0.14
4973 *) Fix content-length computation. We ONLY compute a content-length if
4974 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
4975 or we already have all the data. [Ryan Bloom]
4977 *) Report unbounded containers in the config file. Previously, a typo
4978 in the </container> directive could result in the rest of the config
4979 file being silently ignored, with undesired defaults used.
4982 *) Make the old_write filter use the ap_f* functions for the buffering.
4985 *) Move more code from the http module into the core server. This
4986 is core code, basically the default handler, the default input
4987 and output filters, and all of the core configuration directives.
4988 All of this code is required in order for the server to work, with or
4989 without HTTP. The server is closer to working without the HTTP
4990 module, although there is still more to do. [Ryan Bloom]
4992 *) Fix a number of SGI compile warnings throughout the server. Fix some
4993 bad parameters to apr_bucket_read(). Fix a bad statement in
4994 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
4995 consistently; we were mixing apr_time_t and time_t in invalid ways
4996 before. In load_file(), call apr_dso_error() instead of
4997 apr_strerror() so that we get a more specific string on some platforms.
4998 PR #6980 [Jeff Trawick]
5000 *) Allow modules to query the MPM about it's execution profile. This
5001 query API can and should be extended in the future, but for now,
5002 max_daemons, and threading or forking is a very good start.
5003 [Jon Travis <jtravis covalent.net>]
5005 *) Modify mod_include to send blocks of data no larger than 9k.
5006 Without this, mod_include will wait until the whole file is parsed,
5007 or the first tag is found to send any data to the client.
5008 [Paul J. Reder <rederpj raleigh.ibm.com>]
5010 *) Fix mod_info, so that <Directory> and <Location> directives are
5011 not displayed twice when displaying the current configuration.
5012 [Ryan Morgan <rmorgan covalent.net>]
5014 *) Add config directives to override DEFAULT_ERROR_MSG and
5015 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
5016 [Dan Rench <drench xnet.com>]
5018 *) Get mod_info building and loading on Win32. [William Rowe]
5020 *) Begin to move protocol independant functions out of mod_http. The goal
5021 is to have only functions that are HTTP specific in the http directory.
5024 Changes with Apache 2.0.13
5026 *) Don't assume that there will always be multiple calls to the byterange
5027 filter. It is possible that we will need to do byteranges with only
5028 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
5030 *) Move the error_bucket definition from the http module to the
5031 core server. Every protocol will need this ability, not just
5034 Changes with Apache 2.0.12
5036 *) Modify mod_file_cache to save pre-formatted strings for
5037 content-length and last-modified headers for performance.
5038 [Mike Abbot <mja trudge.engr.sgi.com>]
5040 *) Namespace protect IOBUFSIZ since it is exposed in the API.
5041 [Jon Travis <jtravis covalent.net>]
5043 *) Use "Basic" authentication instead of "basic" in ab, as the spec
5044 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
5046 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
5047 without ever filling it out. This fixes PR 7271.
5048 [Taketo Kabe <kabe sra-tohoku.co.jp> and
5049 Cliff Woolley <cliffwoolley yahoo.com>]
5051 *) Add a couple of GCC attribute tags to printf style functions.
5052 [Jon Travis <jtravis covalent.net>]
5054 *) Add the correct language tag for interoperation with the Taiwanese
5055 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
5057 *) Migrate the perchild MPM to use the new apr signal child, and
5058 APR thread functions. [Ryan Bloom]
5060 *) Close one copy of the CGI's stdout before creating the new process.
5061 The CGI will still have stdout, because we have already dup'ed it.
5062 This keeps Apache from waiting forever to send the results of a CGI
5063 process that has forked a long-lived child process.
5064 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5066 *) Remove the rest of the pthreads functions from the threaded MPM.
5067 This requires the APR support for a signal thread that was just
5070 *) Make mod_dir use a fixup for sending a redirect to the browser.
5071 Before this, we were using a handler, which doesn't make much
5072 sense, because the handler wasn't generating any data, it would
5073 either return a redirect error code, or DECLINED. This fits the
5074 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
5076 *) Make the threaded MPM use APR threads instead of pthreads.
5079 *) Get mod_tls to the point where it actually appears to work in all cases.
5082 *) implement --enable-modules and --enable-mods-shared for "all" and
5083 "most". [Greg Stein]
5085 *) Move the threaded MPM to use APR locks instead of pthread locks.
5088 *) Rename mpmt_pthread to threaded. This is more in line with the
5089 fact that mpmt_pthread shouldn't be using pthreads directly, and
5090 it is a smaller name that doesn't tie into anything.
5093 *) Rename the module structures so that the exported symbol matches
5094 the file name, and it is easier to automate the installation
5095 process (generating LoadModule directives from the module filenames).
5098 *) Remove the coalesce filter. With the ap_f* functions, this filter
5099 is no longer needed. [Ryan Bloom]
5101 Changes with Apache 2.0.11
5103 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
5104 added feature of allowing a uid/gid per child process. If no
5105 uid/gid is specified, then Perchild behaves exactly like dexter.
5108 *) Get perchild building again. [Ryan Bloom]
5110 *) Don't disable threads just because we are using the prefork MPM.
5111 If somebody wants to compile without threads, they must now add
5112 --disable-threads to the configure command line. [Ryan Bloom]
5114 *) Begin to move the calls to update_child_status into common code, so
5115 that each individual MPM does not need to update the scoreboard itself.
5118 *) Allow mod_tls to compile under Unix boxes where openssl has been
5119 installed to the system include files.
5120 [Gomez Henri <new-httpd slib.fr>]
5122 *) Cleanup the mod_tls configure process. This should remove any need
5123 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
5124 configure doesn't check that yet. [Ryan Bloom]
5126 *) Add a very early prototype of SSL support (in mod_tls.c). It is
5127 vital that you read modules/tls/README before attempting to build
5130 *) Fix a potential seg fault on all platforms. David Reid fixed this
5131 on BEOS, but the problem could happen anywhere, so we don't want
5132 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
5134 *) Add new LogFormat directive, %D, to log time it takes to serve a
5135 request in microseconds. [Bill Stoddard]
5137 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
5138 SetOutputFilter. This corresponds nicely with the other Set
5139 directives, which operate on containers while the Add* directives
5140 tend to work directly on extensions. [Ryan Bloom]
5142 *) Cleanup the header handling a bit. This uses the apr_brigade_*
5143 functions for the buffering so that we don't need to compute
5144 the length of the headers before we actually create the header
5145 buffer. [Ryan Bloom]
5147 *) Allow filters to buffer data using the ap_f* functions. These have
5148 become macros that resolve directly to apr_brigade_*.
5151 *) Get the Unix MPM's to do a graceful restart again. If we are going
5152 to register a cleanup with ap_cleanup_scoreboard, then we have to
5153 kill the cleanup with the same function, and that function can't be
5154 static. [Ryan Bloom]
5156 *) Install all required header files. Without these, it was not
5157 possible to compile some modules outside of the server.
5160 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
5161 forward from 1.3 to 2.0, we missed a single line, which broke regex
5162 aliases. [Ryan Bloom]
5164 *) We have a poor abstraction in the protocol. This is a temporary
5165 hack to fix the bug, but it will need to be fixed for real. If
5166 we find an error while sending out a custom error response, we back
5167 up to the first non-OK request and send the data. Then, when we send
5168 the EOS from finalize_request_protocol, we go to the last request,
5169 to ensure that we aren't sending an EOS to a request that has already
5170 received one. Because the data is sent on a different request than
5171 the EOS, the error text never gets sent down the filter stack. This
5172 fixes the problem by finding the last request, and sending the data
5173 with that request. [Ryan Bloom]
5175 *) Make the server status page show the correct restart time, and
5176 thus the proper uptime. [Ryan Bloom]
5178 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
5179 should reduce the amount of duplicate code that is required to
5180 create CGI processes.
5181 [Paul J. Reder <rederpj raleigh.ibm.com>]
5183 *) ap_new_connection() closes the socket and returns NULL if a socket
5184 call fails. Usually this is due to a connection which has been
5185 reset. [Jeff Trawick]
5187 *) Move the Apache version information out of httpd.h and into release.h.
5188 This is in preparation for the first tag with the new tag and release
5189 system. [Ryan Bloom]
5191 *) Begin restructuring scoreboard code to enable adding back in
5192 the ability to use IPC other than shared memory.
5193 Get mod_status working on Windows again. [Bill Stoddard]
5195 *) Make mod_status work with 2.0. This will work for prefork,
5196 mpmt_pthread, and dexter. [Ryan Bloom]
5198 *) Correct a typo in httpd.conf.
5199 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
5201 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
5203 *) Get the correct IP address if ServerName isn't set and we can't
5204 find a fully-qualified domain name at startup.
5205 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
5207 *) Make mod_cgid work with SuExec. [Ryan Bloom]
5209 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
5210 'extra' stat's for user/group since they should never occur, and now
5211 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
5212 volumes. [William Rowe]
5214 *) Adopt apr features to simplify mod_includes. This changes the
5215 behavior of the USER_NAME variable, unknown uid's are now reported
5216 as USER_NAME="<unknown>" rather than the old user#000 result.
5217 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
5219 *) Adopt apr features for simplifing mod_userdir, and accept the new
5220 Win32/OS2 exceptions without hiccuping. [William Rowe]
5222 *) Replace configure --with-optim option by using and saving the
5223 environment variable OPTIM instead. This is needed because configure
5224 options do not support multiple flags separated by spaces.
5227 *) Fix some byterange handling. If we get a byte range that looks like
5228 "-999999" where that is past the end of the file, we should return
5229 a PARTIAL CONTENT status code, and return the whole file as one big
5230 byterange. This matches the 1.3 handling now. [Ryan Bloom]
5232 *) Make the error bucket a real meta-data bucket. This means that the
5233 bucket length is 0, and a read returns NULL data. If one of these
5234 buckets is passed down after the headers are sent, this data will
5235 just be ignored. [Greg Stein]
5237 *) The prefork MPM wasn't killing child processes correctly if a restart
5238 signal was received while the process was serving a request. The child
5239 process would become the equivalent of a second parent process. If
5240 we break out of the accept loop, then we need to do die after cleaning
5241 up after ourselves. [Ryan Bloom]
5243 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
5244 restarts. [Ryan Bloom]
5246 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
5247 the most optimal APR_FINFO_wanted bits. This spares Win32 from
5248 performing very expensive owner, group and permission lookups
5249 and allows the server to function until these apr_finfo_t fields
5250 are implemented under Win32. [William Rowe]
5252 *) Support for typedsafe optional functions - that is functions exported by
5253 optional modules, which, therefore, may or may not be present, depending
5254 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
5255 for sample code. [Ben Laurie]
5257 *) filters can now report an HTTP error to the server. This is done
5258 by sending a brigade where the first bucket is an error_bucket.
5259 This bucket is a simple bucket that stores an HTTP error and
5260 a string. Currently the string is not used, but it may be needed
5261 to output an error log. The http_header_filter will find this
5262 bucket, and output the error text, and then return
5263 AP_FILTER_ERROR, which informs the server that the error web page
5264 has already been sent. [Ryan Bloom]
5266 *) If we get an error, then we should remove all filters except for
5267 those critical to serving a web page. This fixes a bug, where
5268 error pages were going through the byterange filter, even though
5269 that made no sense. [Ryan Bloom]
5271 *) Relax the syntax checking of Host: headers in order to support
5272 iDNS. PR#6635 [Tony Finch]
5274 *) Cleanup the byterange filter to use the apr_brigade_partition
5275 and apr_bucket_copy functions. This removes a lot of very messy
5276 code, and hopefully makes this filter more stable.
5279 *) Remove AddModule and ClearModuleList directives. Both of these
5280 directives were used to ensure that modules could be enabled
5281 in the correct order. That requirement is now gone, because
5282 we use hooks to ensure that modules are in the correct order.
5285 *) When SuExec is specified, we need to add it to the list of
5286 targets to be built. If we don't, then any changes to the
5287 configuration won't affect SuExec, unless 'make suexec' is
5288 specifically run. [Ryan Bloom]
5290 *) Cleaned out open_file from mod_file_cache, as apr now accepts
5291 the APR_XTHREAD argument to open a file for consumption by
5292 parallel threads on win32. [William Rowe]
5294 *) Correct a bug in determining when we follow symlinks. The code
5295 expected a stat -1 result, not an apr_status_t positive error.
5296 Also check if the APR_FINFO_USER fields are valid before we
5297 follow the link. [William Rowe]
5299 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
5300 mpm_common.c. These functions are only valid on some platforms,
5301 so they should not be in the main-line code. [Ryan Bloom]
5303 *) Remove ap_chdir_file(). This function is not thread-safe,
5304 and nobody is currently using it. [Ryan Bloom]
5306 *) Do not try to run make depend if there are no .c files in the
5307 current directory, doing so makes `make depend` fail.
5310 *) Update highperformance.conf to work with either prefork or
5311 pthreads mpms. [Greg Ames]
5313 *) Stop checking to see if this is a pipelined request if we know
5314 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
5315 This keeps us from making an extra read call when serving a 1.0
5316 request. [Ryan Bloom and Greg Stein]
5318 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
5319 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
5320 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
5322 *) Fix the RFC number mentioned when complaining about a missing
5323 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
5325 *) Fix an endless loop in ab which occurred when ab was posting
5326 and the server dropped the connection unexpectedly.
5329 *) Fix a segfault while handling request bodies in ap_http_filter().
5330 This problem has been seen with mod_dav usage as well as with
5331 requests where the body was just being discarded. [Jeff Trawick]
5333 *) Some adjustment on the handling and automatic setting (via
5334 hints.m4) of various compilation flags (eg: CFLAGS). Also,
5335 add the capability to specify flags (NOTEST_CFLAGS and
5336 NOTEST_LDFLAGS) which are used to compile Apache, but
5337 not used during the configuration process. Useful for
5338 flags like "-Werror". [Jim Jagielski]
5340 *) Stop using environment variables to force debug mode or
5341 no detach. We now use the -D command line argument to
5342 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
5343 [Greg Stein, Ryan Bloom]
5345 *) Change handlers to use hooks. [Ben Laurie]
5347 *) Stop returning copies of filenames from both apr_file_t and
5348 apr_dir_t. We pstrdup the filenames that we store in the
5349 actual structures, so we don't need to pstrdup the strings again.
5352 *) mod_cgi: Fix some problems where the wrong error value was being
5353 traced. [Jeff Trawick]
5355 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
5358 *) Add generic hooks. [Ben Laurie]
5360 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
5362 *) Fix a segfault caused by mod_ext_filter when the external filter
5363 program does not exist. [Jeff Trawick]
5365 *) Fix an output truncation error when on an HTTP >= 1.0 request an
5366 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
5367 was served through mod_charset_lite (or anything else that would
5368 create a transient bucket in this size range). ap_bucket_make_heap()
5369 silently failed (fixed), transient_setaside() discovered it, but
5370 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
5372 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
5373 is that some browsers send extra lines at the end of POST requests, and
5374 we don't want to delay sending data back to the user just because the
5375 browser isn't well behaved. [Ryan Bloom]
5377 *) Get SuEXEC working again. We can't send absolute paths to suExec
5378 because it refuses to execute those programs. SuEXEC also wasn't
5379 always recognizing configuration changes made using the autoconf
5382 *) Allow the buildconf process to find the config.m4 files in the correct
5383 order. Basically, we can now name config.m4 files as config\d\d.m4,
5384 and we will sort them correctly when inserting them into the build
5385 process. [Ryan Bloom]
5387 *) Get mod_cgid to use apr calls for creating the actual CGI process.
5388 This also allows mod_cgid to use ap_os_create_priviledged_process,
5389 thus allowing for SuExec execution from mod_cgid. Currently, we do
5390 not support everything that standard SuExec supports, but at least
5391 it works minimally now. [Ryan Bloom]
5393 *) Allow SuExec to be configured from the ./configure command line.
5396 *) Update some of the docs in README and INSTALL to reflect some of
5397 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
5399 *) If we get EAGAIN returned from the call to apr_sendfile, then we
5400 need to call sendfile again. This gets us serving large files
5401 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
5403 *) Get the support programs building cleanly again.
5404 [Cliff Woolley <cliffwoolley yahoo.com>]
5406 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
5407 current directory logic now backs up over bin/ to determine the
5408 server root from the Apache.exe path.
5410 *) Apache/Win32 now follows the standard conventions of mod_foo.so
5411 loadable modules, dynamic libs are all named libfoo.dll, and the
5412 makefile.win populates the include, lib and libexec directories.
5414 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
5415 Apache gets IPv6 listening sockets by default. Additionally, the
5416 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
5417 numeric address strings (e.g., "Listen [fe80::1]:8080").
5420 *) Modify the install directory layout. Modules are now installed in
5421 modules/. Shared libraries should be installed in libraries/, but
5422 we don't have any of those on Unix yet. All install directories
5423 are modifyable at configure time. [Ryan Bloom]
5425 *) Install all header files in the same directory on Unix. [Ryan Bloom]
5427 *) Get the functions in server/linked into the server, regardless of
5428 which modules linked into the server. This uses the same hack
5429 for Apache that we use for APR and apr-util to ensure all of the
5430 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
5431 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
5432 the scripts a bit easier.
5435 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
5436 on the query, and remove IPv4 dependencies. [Jeff Trawick]
5438 *) Get all of the auth modules to the point that they will install and
5439 be loadable into the server. Our new build/install mechanism expects
5440 that all modules will have a common name format. The auth modules
5441 didn't use that format, so we didn't install them properly.
5444 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
5445 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
5447 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
5449 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
5450 after the end of the response. [Ryan Bloom]
5452 *) Get byterange requests working with responses that do not have a
5453 content-length. Because of the way byterange requests work, we have to
5454 have all of the data before we can actually do the byterange, so we
5455 can compute the content-length in the byterange filter.
5458 *) Get exe CGI's working again on Windows.
5461 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
5462 they keep track of whether or not their post config hook has been
5463 called before. Instead of a static variable (which is replaced when
5464 the DSO is loaded a second time), use userdata in the process pool.
5467 Changes with Apache 2.0a9
5469 *) Win32 now requires perl to complete the final install step for users
5470 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
5471 and installs the conf, htdocs and htdocs/manual directories.
5474 *) Make mod_include use a hash table to associate directive tags with
5475 functions. This allows modules to implement their own SSI tags easily.
5476 The idea is simple enough, a module can insert it's own tag and function
5477 combination into a hash table provided by mod_include. While mod_include
5478 parses an SSI file, when it encounters a tag in the file, it does a
5479 hash lookup to find the function that implements that tag, and passes
5480 all of the relevant data to the function. That function is then
5481 responsible for processing the tag and handing the remaining data back
5482 to mod_include for further processing.
5483 [Paul J. Reder <rederpj raleigh.ibm.com>]
5485 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
5486 fewer parameters: the local and remote socket addresses were removed
5487 from the parameter list because all required information is available
5488 via the APR socket. [Jeff Trawick]
5490 *) Distribution directory structure reorganized to reflect a
5491 normal source distribution with external install targets.
5494 *) The MPMs that need multiple segments of shared memory now create
5495 two apr_shmem_t variables, one for each shared memory allocation.
5496 the problem is that we can't determine how much memory will be required
5497 for shared memory allocations once we try to allocate more than one
5498 variable. The MM code automatically aligns the shared memory allocations,
5499 so we end up needing to pad the amount of shared memory we want based
5500 on how many variables will be allocated out of the shared memory segment.
5501 It is just easier to create a second apr_shmem_t variable, and two
5502 shmem memory blocks.
5505 *) Cleanup the export list a bit. This creates a single unified list of
5506 functions exported by APR. The export list is generated at configure
5507 time, and that list is then used to generate the exports.c file.
5508 Because of the way the export list is generated, we only export those
5509 functions that are valid on the platform we are building on.
5512 *) Enable logging the cookie with mod_log_config
5513 [Sander van Zoest <sander covalent.net>]
5515 *) Fix a segfault in mod_info when it reaches the end of the configuration.
5518 *) Added lib/aputil/ as a placeholder for utility functions which are not
5519 specific to the Apache HTTP Server (but do not make sense with APR).
5520 The first utility is "apu_dbm": a set of functions to work with DBM
5521 files. This first version can be compiled for SDBM or GDBM databases.
5524 *) Complete re-write of mod_include. This makes mod_include a filter that
5525 uses buckets directly. This has now served the FAQ correctly.
5526 [Paul Reder <rederpj raleigh.ibm.com>]
5528 *) Allow modules to specify the first filter in a sub_request when
5529 making the sub_request. This keeps modules from having to change the
5530 output_filter immediately after creating the sub-request, and therefore
5531 skip the sub_req_output_filter. [Ryan Bloom]
5533 *) Update ab to accept URLs with IPv6 literal address strings (in the
5534 format described in RFC 2732), and to build Host header fields in
5535 the same format. This allows IPv6 literal address strings to be
5536 used with ab. This support has been tested against Apache 1.3 with
5537 the KAME patch, but Apache 2.0 does not yet work with this format
5538 of the Host header field. [Jeff Trawick]
5540 *) Accomodate an out-of-space condition in the piped logs and the
5541 rotatelogs.c code, and no longer churn log processes for this
5542 condition. [Victor J. Orlikowski]
5544 *) Add support for partial writes with apr_sendfile() to core_output_filter.
5547 Changes with Apache 2.0a8
5549 *) Add a directive to mod_mime so that filters can be associated with
5553 *) Get multi-views working again. We were setting the path_info
5554 field incorrectly if we couldn't find the specified file.
5557 *) Fix 304 processing. The core should never try to send the headers
5558 down the filter stack. Always, just setup the table in the request
5559 record, and let the header filter convert it to data that is ready
5563 *) More fixes for the proxy. There are still bugs in the proxy code,
5564 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
5568 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
5571 *) APR: Add new apr_getopt_long function to handle long options.
5572 [B. W. Fitzpatrick <fitz red-bean.com>]
5574 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
5575 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
5576 hostname resolution/address string parsing and building
5577 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
5578 of one of the apr_sockaddr_t structures for a socket. Change
5579 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
5581 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
5582 I have proxied pages with it, cleanup will commence soon.
5585 *) Make the proxy work with filters. This isn't perfect, because we
5586 aren't dealing with the headers properly. [Ryan Bloom]
5588 *) Do not send a content-length iff the C-L is 0 and this is a head
5589 request. [Ryan Bloom]
5591 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
5592 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
5594 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
5596 *) Get the default_handler to stop trying to deal with HEAD requests.
5597 The idea is to let the content-length filter compute the C-L before
5598 we try to send the data. If we can get the C-L correctly, then we
5599 should send it in the HEAD response.
5602 *) The Header filter can now determine if a body should be sent based
5603 on r->header_only. The general idea of this is that if we delay
5604 deciding to send the body, then we might be able to compute the
5605 content-length correctly, which will help caching proxies to cache
5606 our data better. Any handler that doesn't want to try to compute
5607 the content-length can just send an EOS bucket without data and
5608 everything will just work.
5611 *) Add the referer to the error log if one is available.
5612 [Markus Gyger <mgyger itr.ch>]
5614 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
5615 change, the root of the configuration tree has been exposed to modules
5617 [Ryan Morgan <rmorgan covalent.net>]
5619 *) Get the core_output_filter to use the bucket interface directly.
5620 This keeps us from calling the content-length filter multiple times
5621 for a simple static request.
5624 *) We are sending the content-type correctly now.
5625 [Ryan Bloom and Will Rowe]
5627 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
5628 a bogus bytes-sent value when the only thing being sent was trailers
5629 and writev() returned an error (or EAGAIN). [Jeff Trawick]
5631 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
5632 hints file to determine which platforms define
5633 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
5636 *) APR: add apr_get_home_directory() [Jeff Trawick]
5638 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
5640 *) Not all platforms have INADDR_NONE defined by default. Apache
5641 used to make this check and define INADDR_NONE if appropriate,
5642 but APR needs the check too, and I suspect other applications will
5643 as well. APR now defines APR_INADDR_NONE, which is always a valid
5644 value on all platforms.
5645 [Branko Èibej <brane xbc.nu>]
5647 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
5648 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
5650 *) Relax the syntax checking of Host: headers in order to support
5651 iDNS. PR#6635 [Tony Finch]
5653 *) When reading from file buckets we convert to an MMAP if it makes
5654 sense. This also simplifies the default handler because the
5655 default handler no longer needs to try to create MMAPs.
5658 *) BUFF has been removed from the main server. The BUFF code will remain
5659 in the code until it has been purged from the proxy module as well.
5662 *) Byteranges have been completely re-written to be a filter. This
5663 has been tested, and I believe it is working correctly, but it could
5664 doesn't work for the Adobe Acrobat plug-in. The output almost matches
5665 the output from 1.3, the only difference being that 1.3 includes
5666 a content-length in the response, and this does not.
5669 *) APR read/write functions and bucket read functions now operate
5670 on unsigned integers, instead of signed ones. It doesn't make
5671 any sense to use signed ints, because we return the error codes,
5672 so if we have an error we should report 0 bytes read or written.
5675 *) Always compute the content length, whether it is sent or not.
5676 The reason for this, is that it allows us to correctly report
5677 the bytes_sent when logging the request. This also simplifies
5678 content-length filter a bit, and fixes the actual byte-reporing
5679 code in mod_log_config.c
5682 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
5683 it says, because it was only used by EOS and FLUSH buckets. Since
5684 neither of those are required at the end of a brigade, this was
5685 really signifying FLUSH_THE_DATA, but that can be determined better
5686 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
5687 buckets now return a length of 0, which is actually the amount of data
5688 read, so they make more sense.
5691 *) Allow the core_output_filter to save some data past the end of a
5692 request. If we get an EOS bucket, we only send the data if it
5693 makes sense to send it. This allows us to pipeline request
5694 responses. As a part of this, we also need to allocate mmap
5695 buckets out of the connection pool, not the request pool. This
5696 allows the mmap to outlive the request.
5699 *) Make blocking and non-blocking bucket reads work correctly for
5700 sockets and pipes. These are the only bucket types that should
5701 have non-blocking reads, because the other bucket types should
5702 ALWAYS be able to return something immediately.
5705 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
5706 server, but use Ctrl+Break to initiate a graceful restart
5707 instead of duplicating behavior. [John Sterling]
5709 *) Patch mod_autoindex to set the Last-Modified header based on
5710 the directory's mtime, and add the ETag header. [William Rowe]
5712 *) Merge the 1.3 patch to add support for logging query string in
5713 such a way that "%m %U%q %H" is the same as "%r".
5716 *) Port three log methods from mod_log_config 1.3 to 2.0:
5717 CLF compliant '-' byte count, method and protocol.
5720 *) Add a new LogFormat directive, %c, that will log connection
5721 status at the end of the response as follows:
5722 'X' - connection aborted before the response completed.
5723 '+' - connection may be kept-alive by the server.
5724 '-' - connection will be closed by the server.
5727 *) Expand APR for WinNT to fully accept and return utf-8 encoded
5728 Unicode file names and paths for Win32, and tag the Content-Type
5729 from mod_autoindex to reflect that charset if the feature
5730 macro APR_HAS_UNICODE_FS is true. [William Rowe]
5732 *) Compute the content length (and add appropriate header field) for
5733 the response when no content length is available and we can't use
5734 chunked encoding. [Jeff Trawick]
5736 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
5737 so that content input filters get dechunked data when using
5738 the default handler. Also removed REQUEST_CHUNKED_PASS.
5741 *) Add mod_ext_filter as an experimental module. This module allows
5742 the administrator to use external programs as filters. Currently,
5743 only filtering of output is supported. [Jeff Trawick]
5745 *) Most Apache functions work on EBCDIC machines again, as protocol
5746 data is now translated (again). [Jeff Trawick]
5748 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
5749 the EBCDIC support. They are noops on ASCII machines, so this
5750 type of translation doesn't have to be surrounded by #ifdef
5751 CHARSET_EBCDIC. [Jeff Trawick]
5753 *) Fix mod_include. tag commands work again, and the server will
5754 send the FAQ again. This also allows mod_include to set aside
5755 buckets that include partial buckets.
5756 [Ryan Bloom and David Reid]
5758 *) Add suexec support back. [Manoj Kasichainula]
5760 *) Lingering close now uses the socket directly instead of using
5761 BUFF. This has been tested, but since all we can tell is that it
5762 doesn't fail, this needs to be really hacked on.
5765 *) Allow filters to modify headers and have those headers be sent to
5766 the client. The idea is that we have an http_header filter that
5767 actually sends the headers to the network. This removes the need
5768 for the BUFF to send headers.
5771 *) Charset translation: mod_charset_lite handles translation of
5772 request bodies. Get rid of the xlate version of ap_md5_digest()
5773 since we don't compute digests of filtered (e.g., translated)
5774 response bodies this way anymore. (Note that we don't do it at
5775 all at the present; somebody needs to write a filter to do so.)
5778 *) Input filters and ap_get_brigade() now have a input mode parameter
5779 (blocking, non-blocking, peek) instead of a length parameter.
5782 *) Update the mime.types file to the registered media types as
5783 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
5786 *) Namespace protect some macros declared in ap_config.h
5789 *) Support HTTP header line folding with input filtering.
5792 *) Mod_include works again. This should still be re-written, but at
5793 least now we can serve an SHTML page again.
5796 *) Begin to remove BUFF from the core. Currently, we keep a pointer
5797 to both the BUFF and the socket in the conn_rec. Functions that
5798 want to use the BUFF can, functions that want to use the socket,
5799 can. They point to the same place.
5802 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
5803 [Tomas "Ögren" <stric ing.umu.se>]
5805 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
5806 associated pool goes away. (APR pipes on OS/2 were already had this
5807 logic.) This resolvs a fatal file descriptor leak with CGIs.
5810 *) The final line of the config file was not being read if there was
5811 no \n at the end of it. This was caused by apr_fgets returning
5812 APR_EOF even though we had read valid data. This is solved by
5813 making cfg_getline check the buff that was returned from apr_fgets.
5814 If apr_fgets return APR_EOF, but there was data in the buf, then we
5815 return the buf, otherwise we return NULL.
5818 *) Piped logs work again in the 2.0 series.
5821 *) Restore functionality broken by the mod_rewrite security fix:
5822 rewrite map lookup keys and default values are now expanded
5823 so that the lookup can depend on the requested URI etc.
5824 PR #6671 [Tony Finch]
5826 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
5827 security bug in some mass virtual hosting configurations
5828 that can allow a remote attacker to retrieve some files
5829 on the system that should be inaccessible. [Tony Finch]
5831 *) Add a pool bucket type. This bucket is used for data allocated out
5832 of a pool. If the pool is cleaned before the bucket is destroyed, then
5833 the data is converted to a heap bucket, allowing it to survive the
5837 *) Add a flush bucket. This allows modules to signal that the filters
5838 should all flush whatever data they currently have. There is no way
5839 to actually force them to do this, so if a filter ignores this bucket,
5840 that's life, but at least we can try with this.
5843 *) Add an output filter for sub-requests. This filter just strips the
5844 EOS bucket so that we don't confuse the main request's core output
5845 filter by sending multiple EOS buckets. This change also makes sub
5846 requests start to send EOS buckets when they are finished.
5849 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
5850 makes ap_bucket_destroy a return void, which is okay because it
5851 used to always return APR_SUCCESS, and nobody ever checked its
5852 return value anyway.
5853 [Cliff Woolley <cliffwoolley yahoo.com>]
5855 *) Remove the index into the bucket-type table from the buckets
5856 structure. This has now been replaced with a pointer to the
5857 bucket_type. Also add some macros to test the bucket-type.
5860 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
5861 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
5862 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
5863 All _VAR_ flavors changes to _DATA to be absolutely clear.
5866 *) Add support for /, //, //servername and //server/sharename
5867 parsing of <Directory> blocks under Win32 and OS2.
5868 [Tim Costello, William Rowe, Brian Harvard]
5870 *) Remove the function pointers from the ap_bucket type. They have been
5871 replaced with a global table. Modules are allowed to register bucket
5872 types and use then use those buckets.
5875 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
5876 once we finish writing the request body to the cgi child process;
5877 otherwise, the client doesn't hit EOF on stdin. Small request bodies
5878 worked without this change (for reasons I don't understand), but large
5879 ones didn't. [Jeff Trawick]
5881 *) Remove file bucket specific information from the ap_bucket type.
5882 This has been moved to a file_bucket specific type that hangs off
5883 the data pointer in the ap_bucket type.
5886 *) Input filtering now has a third argument. This is the amount of data
5887 to read from lower filters. This argument can be -1, 0, or a positive
5888 number. -1 means give me all the data you have, I'll deal with it and
5889 let you know if I need more. 0 means give me one line and one line
5890 only. A positive number means I want no more than this much data.
5892 Currently, only 0 and a positive number are implemented. This allows
5893 us to remove the remaining field from the conn_rec structure, which
5897 *) Big cleanup of the input filtering. The goal is that http_filter
5898 understands two conditions, headers and body. It knows where it is
5899 based on c->remaining. If c->remaining is 0, then we are in headers,
5900 and http_filter returns a line at a time. If it is not 0, then we are
5901 in body, and http_filter returns raw data, but only up to c->remaining
5902 bytes. It can return less, but never more.
5903 [Greg Ames, Ryan Bloom, Jeff Trawick]
5905 *) mod_cgi: Write all of the request body to the child, not just what
5906 the kernel would accept on the first write. [Jeff Trawick]
5908 *) Back out the change that moved the brigade from the core_output_filters
5909 ctx to the conn_rec. Since all requests over a given connection
5910 go through the same core_output_filter, the ctx pointer has the
5914 *) Fix another bug in the send_the_file() read/write loop. A partial
5915 send by apr_send would cause unsent data in the read buffer to
5916 get clobbered. Complete making send_the_file handle partial
5917 writes to the network.
5920 *) Fix a couple of type fixes to allow compilation on AIX again
5921 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
5923 *) Fix bug in send_the_file() which causes offset to be ignored
5924 if there are no headers to send.
5927 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
5928 filter. Useful for supporting Windows 9* with a binary
5929 compiled on Windows NT.
5932 Changes with Apache 2.0a7
5934 *) Reimplement core_output_filter to buffer/save bucket brigades
5935 across multiple calls to the core_filter. The brigade will be
5936 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
5937 thresholds are hit or the EOS bucket is received.
5940 *) Create experimental filter (buffer_filter) that coalesces bytes
5941 into one large buffer before invoking the next filter in the
5942 chain. This filter is particularly useful with the current
5943 implementation of mod_autoindex when it inserted above the
5944 chunk_filter. mod_autoindex generates a lot of brigades that
5945 containing buckets holding just a few bytes each. The
5946 buffer_filter coalesces these buckets into a single large bucket.
5949 *) Add apr_sendfile() support into the core_output_filter.
5952 *) Add apr_sendv() support into the core_output_filter.
5955 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
5956 [Mike Abbott <mja sgi.com>]
5958 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
5959 make much sense, because Apache uses buckets instead of BUFFs now.
5962 *) send_the_file now falls back to a read/write loop on platforms that
5963 do not have sendfile.
5964 [Ryan Bloom and Brian Havard]
5966 *) Install apachectl correctly, and substitute the proper values so
5967 that it works again. [Ryan Bloom]
5969 *) Better(??) handle platforms that lack sendfile().
5972 *) APR now has UUID generation/formatting/parsing support.
5975 *) Begin the http_filter. This is an input filter that understands
5976 the absolute basic amount required to parse an HTTP Request. The
5977 goal is to be able to split headers from request body before passing
5978 the data back to the other filters.
5981 *) Bring forward from 1.3.13 the config directory implementation
5984 *) install apxs if it is created
5987 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
5988 conversions. [William Rowe]
5990 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
5991 ap_add_output_filter(). [Jeff Trawick]
5993 *) Multiple build and configuration fixes
5996 -add datadir and localstatedir substitutions
5998 -fix logfilename misspelling
5999 -fix evaluation of installation dir variables and
6000 -replace $foobar by $(foobar) to be usefull in the makefile
6004 -add rules for cross-compiling in rules.mk. Okay, rule to check for
6005 $CC_FOR_BUILD is still missing
6006 -use CHECK_TOOL instead of CHECK_PROG for ranlib
6007 -add missing "AR=@AR@" to severaly Makefile.in's
6008 -cache result for "struct rlimit"
6009 -compile all helper programs with native and cross compiler
6010 and use the native version to generate header file

6013 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
6015 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
6017 *) Fix a bug where a client which only sends \n to delimit header
6018 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
6019 message. Start working on ebcdic co-existance with input
6021 [William Rowe, Greg Ames]
6023 *) If mod_so is enabled in the server always create libexec, even
6024 if there are no modules installed in this directory. This is a
6025 requirement for APXS to work correctly.
6028 *) Connection oriented output filters are now stored in the
6029 conn_rec instead of the request_rec. This allows us to add the
6030 output filter in the pre-connection phase instead of the
6031 post_read_request phase, which keeps us from trying to write an
6032 error page before we have a filter to write to the network.
6033 [Ryan Bloom, Jeff Trawick, and Greg Ames]
6035 *) Cleaning up an mmap bucket no longer deletes the mmap. An
6036 mmap can be used across multiple buckets (default_handler with
6037 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
6038 the mmap itself can't be associated with the bucket.
6041 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
6044 *) Radical surgery to improve mod_isapi support under Win32.
6045 Includes a number of newer ServerSupportFunction calls, support
6046 for ReadClient (in order to retrieve POSTs greater than 48KB),
6047 and general bug fixes to more reliably load ISAPI .dll's and
6048 prevent leaking handle resources. Note: There are still
6049 discrepancies between IIS's and Apache's ServerVariables, and
6050 async calls are still not supported. Additional warnings are
6051 logged to facilitate debugging of unsupported ISAPI calls.
6054 *) Add input filtering to Apache. The basic idea for the input
6055 filters is the same as the ideas for output filters. The biggest
6056 difference is that instead of calling ap_pass_brigade, ap_get_brigade
6057 should be called, and the order of execution for the filter itself is
6058 different. When writing an output filter, a brigade is passed in,
6059 and filters operate directly on that brigade, when done, they call
6060 ap_pass_brigade. Input filters are the exact opposite. Because input
6061 is not a push operation, filters first call ap_get_brigade. When this
6062 function returns, the input filter will be left with a valid brigade.
6063 The input filter should then operate on the brigade, and return.
6066 *) Fix building on BSD/OS using its native make. The build system
6067 falls back to the BSD .include directive on that host platform.
6070 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
6071 SHA1 and plaintext password encodings. Make feature tests a
6072 bit more flexible. [William Rowe]
6074 *) Charset translation: mod_charset_lite handles output content
6075 translation in a filter. mod_charset_lite no longer ignores
6076 subrequests. A bunch of cruft related to BUFF's support for
6077 translating request and response bodies was removed.
6080 *) Move the addition of the CORE filter to the post_read_request
6081 hook in http_core.c. This removes the need to add the filter in
6082 multiple places and allows for an SSL module to be added much
6083 simpler. [Ryan Bloom]
6085 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
6086 Fix a security problem that affects certain configurations of
6087 mod_rewrite. If the result of a RewriteRule is a filename that
6088 contains expansion specifiers, especially regexp backreferences
6089 $0..$9 and %0..%9, then it may be possible for an attacker to
6090 access any file on the web server. [Tony Finch]
6092 *) Fix a bug where errors that are detected during early request parsing
6093 don't produce visible HTTP error messages at the browser, because
6094 the core_filter wasn't present. [Greg Ames]
6096 *) Provide apr_socklen_t as a portability aid.
6097 [Victor J. Orlikowski]
6099 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
6100 as well as a comment arg to the add, adduser and update cmds.
6101 update allows the user to clear or preserve pw/groups/comment.
6102 Fixed a bug in dbmmanage that prevented the check option from
6103 parsing a password followed by :group... text. Corrected the
6104 seed calcualation for Win32 systems, and added -lsdbm support.
6107 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
6110 *) Avoid a segfault when parsing .htaccess files. An
6111 uninitialized tree pointer was passed to ap_build_config().
6114 *) Change the way that inet_addr & inet_network are checked for
6115 in APR's configure process to allow BeOS BONE to correctly
6116 find them. With this change BeOS BONE now builds from source
6117 with no problems. [David Reid]
6119 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
6120 the end of the parameters to execve() was stored in the wrong
6121 location, overlaying the storage beyond the newargs[] array and
6122 also passing uninitialized storage to execve(), which would
6123 sometimes fail with EFAULT. [Jeff Trawick]
6125 *) Fix a bug parsing configuration file containers. With a sequence
6126 like this in the config file
6128 <IfModule mod_kilroy.c>
6131 <IfModule mod_lovejoy.c>
6136 the second container would be terminated at the blank line due to
6137 sediment in the buffer from reading the prior </IfModule> and an
6138 error message would be generated for the real </IfModule> for the
6139 second container. Also due to this problem, any two characters
6140 could be used for "</" in the close of a container.
6143 *) ap_add_filter prototype changed to remove the ctx pointer. The
6144 pointer still remains in the filter structure, but it can not be
6145 a part of the ap_add_filter prototype. The reason is that when
6146 the core uses AddFilter to add a filter to the stack it doesn't
6147 know how to allocate the ctx pointer, or even how much memory should
6148 be allocated. The filters will have to be responsible for allocating
6149 the ctx memory when they need it.
6152 *) Add an AddFilter directive. This directive takes a list of filters
6153 that should be activated for the requested resource.
6156 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
6157 some other platforms). [Jeff Trawick]
6159 *) Modify mod_include to be a filter. Currently, it has only been tested
6160 on actual files, but it should work for CGI scripts too.
6163 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
6164 writes. apr_flush() for Unix: handle interrupted writes.
6167 *) NameVirtualHost can now take "*" as an argument instead of
6168 an IP address. This allows you to create a purely name-based
6169 virtual hosting server that does not have any IP addresses in
6170 the configuration file and which ignores the local address
6171 of any connections. PR #5595, PR #4455 [Tony Finch]
6173 *) Fix some compile warnings in mod_mmap_static.c
6174 [Mike Abbott <mja sgi.com>]
6176 *) Fix chunking problem with CGI scripts. The general problem was that
6177 the CGI modules were adding an EOS bucket and then the core added an
6178 EOS bucket. The chunking filter finalizes the chunked response when it
6179 encounters an EOS bucket. Because two EOS buckets were sent, we
6180 finalized the response twice. The fix is to make sure we only send one
6181 EOS, by utilizing a flag in the request_rec.
6184 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
6185 and Win32. Previously, the first read from an apr_file_t set up via
6186 apr_put_os_file() would return a '\0'. [Jeff Trawick]
6188 *) Mod_cgid now creates a single element bucket brigade, with a pipe
6189 bucket, instead of using BUFF's and ap_r*.
6192 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
6193 [Mike Abbott <mja sgi.com>]
6195 *) Remove ap_bopenf from buff code. This required modifying the file_cache
6196 code to use APR file's directly instead of going through BUFFs.
6199 *) Fix compile break on some platforms for mod_mime_magic.c
6200 [John K. Sterling <sterling covalent.net>]
6202 *) Fix merging of AddDefaultCharset directive.
6203 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
6205 *) Minor revamp of the rlimit sections of code. We now test
6206 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
6207 is now "available" even if the platform doesn't support
6208 the rlimit family (it's just a noop though). [Jim Jagielski]
6210 *) Migrate the pre-selection of which MPM to use for specific
6211 platforms to hints.m4, which contains (or should contain)
6212 all platform specific "hints". [Jim Jagielski]
6214 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
6217 *) Add tables with non-string/binary values to APR.
6220 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
6223 *) Update PCRE to version 3.2. [Ryan Bloom]
6225 *) Change the way buckets' destroy functions are called so that
6226 they can be more directly used when changing the type of a
6227 bucket in place. [Tony Finch]
6229 *) Add generic support for reference-counting the resources used by
6230 buckets, and alter the HEAP and MMAP buckets to use it. Change
6231 the way buckets are initialised to support changing the type of
6232 buckets in place, and use it when setting aside TRANSIENT buckets.
6233 Change the implementation of TRANSIENT buckets so that it can be
6234 mostly shared with IMMORTAL buckets, which are now implemented.
6237 Changes with Apache 2.0a6
6239 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
6241 *) Add a chunking filter to Apache. This brings us one step closer
6242 to removing BUFF. [Ryan Bloom]
6244 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
6245 added to the stack is the last filter to be called. [Ryan Bloom]
6247 *) Apache 2.0 has been completely documented using Scandoc. The
6248 docs can be generated by running 'make docs'. [Ryan Bloom]
6250 *) Add filtered I/O to Apache. This is based on bucket brigades,
6251 Currently the buckets still use BUFF under the covers, but that
6252 should change quickly. The only currently written filter is the
6253 core filter which just calls ap_bwrite. [The Apache Group]
6255 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
6256 built with thread support. [Jeff Trawick]
6258 *) Abort configuration if --with-layout was specified and there's
6259 no layout definition file. [Ken Coar]
6261 *) Add support for '--with-port=n' option to configure. [Ken Coar]
6263 *) Add support for extension methods for the Allow response header
6264 field, and an API routine for accessing r->allowed and the
6265 list of extension methods in a unified manner. [Ken Coar]
6267 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
6268 [Rob Simonson <simo us.ibm.com>]
6270 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
6271 APACHE_XLATE builds. [Jeff Trawick]
6273 *) A configuration file parsing problem was fixed. When the
6274 configuration file started with an IfModule/IfDefine container,
6275 only the last statement in the container would be retained.
6278 Changes with Apache 2.0a5
6280 *) Perchild is serving pages after passing them to different child
6281 processes. There are still a lot of bugs, but this does work. I
6282 have made requests against the same installation of Apache, and had
6283 different servers use different user IDs to serve the responses.
6284 This change moves to using socketpair instead of an AF_UNIX socket.
6287 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
6288 It can't seem to pass between child processes yet, but I think we
6289 are closer now than before. This moves us back to using Unix
6290 Domain Sockets. [Ryan Bloom]
6292 *) libapr functions and types renamed with apr_ prefix.
6293 #include "apr_compat.h" for 1.3.x backwards compat
6296 *) Fix problems with APR sockaddr handling on Win32. It didn't always
6297 return the right information on the local socket address.
6298 [Gregory Nicholls <gnicholls level8.com>]
6300 *) ap_recv() on Win32: Set bytes-read to 0 on error.
6301 [Gregory Nicholls <gnicholls level8.com>]
6303 *) Add an option to not detach from the controlling terminal without
6304 going into single process mode. This allows for much easier
6305 debugging of the process startup code. [Ryan Bloom]
6307 *) ab: don't use perror() to report the failure of an APR function.
6310 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
6311 scoreboard on graceful restarts.
6314 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
6315 An invalid ap_proc_t was passed to ap_create_process().
6318 *) Allow modules to register filters. Those filters are still
6319 never called, but this is a step in the right direction.
6320 [Ryan Bloom and Greg Stein]
6322 *) Register the mod_cgid daemon process for cleanup so that it is
6323 killed at termination if it does not die when the parent gets
6324 SIGTERM. This change is to fix occasional problems where the
6325 process stays around. Bugs in similar logic in mod_rewrite and
6326 mod_include were also fixed. [Jeff Trawick]
6328 *) Fix a bug in the time handling. Basically, we were imploding a time
6329 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
6330 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
6331 uses those two fields to adjust the time value. Because of the HTTP
6332 spec, both of those values can be zero'ed out safely. This fixes
6333 the bug correctly. [Ryan Bloom]
6335 *) Fix a couple of place in the Windows code where the wrong error
6336 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
6338 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
6340 *) Added the APR_EOL_STR macro for platform dependent differences in
6341 logfiles and other raw text (such as all APR files). Fixes logfiles
6342 not terminated with cr/lf sequences in Win32. [William Rowe]
6344 *) Move all strings functions in APR to src/lib/apr/strings and create
6345 apr_strings.h for the prototypes. [Ryan Bloom]
6347 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
6348 to repeat the syscall until we stop getting EINTR. I noticed a
6349 related problem at termination (SIGTERM) on FreeBSD when using
6350 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
6351 implementation work properly with child init. Previously, ap_lock()
6352 was essentially a no-op because all children were using different
6353 locks and thus nobody ever blocked. [Jeff Trawick]
6355 *) The htdocs/ tree has been moved out of the CVS source tree into
6356 a separate area for easier development. This has NO EFFECT on
6357 end-users or Apache installations. [Ken Coar]
6359 *) Integrate the mod_dav module for WebDAV protocol handling. This
6360 adds the dav and dav_fs modules, the SDBM library, and additional
6361 XML handling utilities. [Greg Stein]
6363 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
6366 *) Update the lib/expat-lite/ library (bring forward changes from
6367 the Apache 1.3 repository). [Greg Stein]
6369 *) If sizeof(long long) == sizeof(long), then prefer long in APR
6370 configure.in. [Dave Hill <ddhill zk3.dec.com>]
6372 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
6373 machines where sendfile is detected, but nobody has written ap_sendfile.
6374 [Dave Hill <ddhill zk3.dec.com>]
6376 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
6378 *) ab would start up more connections than needed, then quit when the
6379 desired number were finished. Also fixed a logic error involving
6380 ab keepalives. [Victor J. Orlikowski]
6382 *) WinNT: Implement non-blocking pipes with timeouts to communicate
6383 with CGIs. Apache 2.0a4 had non-blocking pipes but without
6384 timeouts (i.e, if a timeout was specified, the pipe reverted to
6385 a full blocking pipe). Now the behaviour is more in line with
6386 Unix non-blocking pipes.
6389 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
6390 cache open file handles along with accept socket reuse enables
6391 Apache 2.0 to serve non-keepalive requests for static files at
6392 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
6393 and Apache 2.0 will serve almost 1200 rps on my system).
6396 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
6397 supports two config directives, mmapfile (same behavious as
6398 mod_mmap_static) and cachefile. Use the cachefile directive
6399 to cache open file handles. This directive only works on systems
6400 that have implemented the ap_sendfile API. cachefile works today
6401 on Windows NT, but has not been tested on any flavors of Unix.
6404 *) Cleanup the configuration. With the last few changes the
6405 configuration process automatically:
6406 inherits information about how to build from APR. Allowing
6407 APR to inform Apache that it should or should not use -ldl
6409 Detects which mod_cgi should be used mod_cgi or mod_cgid,
6410 based on the threading model
6412 Apache calls APR's configure process before finishing it's
6413 configuration processing, allowing for more information flow
6418 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
6419 with non-zero argument makes the socket non-blocking. BeOS and
6420 OS/2 already worked this way. [Jeff Trawick]
6422 *) ap_close() now calls ap_flush() for buffered files, so write
6423 operations work a whole lot better on buffered files.
6426 *) Fix error messages issued from MPMs which explain where to change
6427 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
6430 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
6431 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
6432 now the way that the blocking state of a pipe is manipulated.
6433 ap_block_pipe() is gone. [Jeff Trawick]
6435 *) Correct the problem where the only local host name that the IP stack
6436 can discover are 'undotted' private names. If no fully qualified
6437 domain name can be identified, the default ServerName will be set to
6438 the machine's IP address string. A warning is always provided if the
6439 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
6441 *) Repair problems with config file processing which caused segfault
6442 at init when virtual hosts were defined and which caused ServerName to
6443 be ignored when there was no valid DNS setup. [Jeff Trawick]
6445 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
6447 *) Add ap_sendfile implementation for AIX
6448 [Victor J. Orlikowski]
6450 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
6451 apr_network_io.h, and apr_thread_proc.h.
6452 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
6454 *) Bring the allocation and pool debugging code back into a working
6455 state. This will need to be tested as so far it's only been used on
6458 *) Change configuration command setup to be properly typesafe when in
6459 maintainer mode. Note that this requires a compiler that can initialise
6460 unions. [Ben Laurie]
6462 *) Turn on buffering for config file reads. Part of this was to
6463 repair buffered I/O support in Unix and implement buffered
6464 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
6466 *) Win32: Fix problem where UTC offset was not being set correctly
6467 in the access log. Problem reported on news group by Jerry Baker.
6470 *) Fix segfault when reporting this type of syntax error:
6471 "</container> without matching <container> section", where
6472 container is VirtualHost or Directory or whatever.
6475 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
6476 Prevent the source code for CGIs from being revealed when
6477 using mod_vhost_alias and the CGI directory is under the document root
6478 and a user makes a request like http://www.example.com//cgi-bin/cgi
6479 as reported in <news:960999105.344321 ernani.logica.co.uk>
6482 *) Add support for the new Beos NetwOrking Environment (BONE)
6485 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
6486 final input char is incomplete; ap_bwrite_xlate() now handles
6487 incomplete final input chars. [Jeff Trawick]
6489 *) Yet another update to saferead/halfduplex stuff -- need to ensure
6490 that a bhalfduplex call occurs before logging or else DNS and
6491 such can delay the last packet of the response. [Dean Gaudet]
6493 *) Some syscall reduction in APR on unix -- don't seek when setting
6494 up an mmap; and don't fcntl() more than once per socket.
6497 *) When mod_cgid is started as root, the cgi daemon now switches
6498 to the configured User/Group (like other httpd processes)
6499 instead of continuing as root. [Jeff Trawick]
6501 *) The prefork MPM now uses an APR lock for the accept() mutex.
6502 It has not been getting a lock at all recently. httpd -V now
6503 displays APR's selection of the lock mechanism instead of the
6504 symbols previously respected by prefork. [Jeff Trawick]
6506 *) Change the mmap() feature test to check only for existence.
6507 The previous check required features not used by Apache.
6510 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
6511 sometimes mangled. The len parm to accept() was not
6512 initialized, leading sometimes to an endless loop of failed
6513 accept() calls on OS/390 and anywhere else that failed the call
6514 if the len was negative. Use <sys/un.h> for struct sockaddr_un
6515 instead of declaring it ourselves to fix a compilation problem
6516 on Solaris. [Jeff Trawick]
6518 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
6520 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
6522 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
6524 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
6525 initialization if ALLOC_DEBUG is defined; no known symptom
6526 otherwise. [Jeff Trawick]
6528 *) Fix typo in configure script when checking for mod_so. bash
6529 doesn't seem to have a problem but /bin/sh on Solaris does.
6530 Symptom: "./configure: test: unknown operator =="
6533 *) Rebind the Win32 NT and 9x services control into the MPM.
6534 All console, WinNT SCM and Win9x pseudo-service control code is
6535 now wrapped within the WinNT MPM.
6538 *) Make a copy of getenv("PATH") before storing for later use. Some
6539 getenv() implementations use the same storage for successive calls.
6540 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
6542 *) Server Tokens work in 2.0 again. This also propogates the change
6543 to allow just the product name in the server string using
6547 Changes with Apache 2.0a4
6549 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
6550 won't need to call it. [Greg Ames, Jeff Trawick]
6552 *) Move pre_config hook call to between configuration read and config
6553 tree walk. This allows all modules to implement pre_config hooks
6554 and know that they will be called at an appropriate time.
6557 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
6560 *) Add pre-config hooks back to all modules.
6563 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
6564 ContentDigest enabled and we can't/don't mmap the file.
6567 *) We now report the correct line number for syntax errors in config
6568 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
6570 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
6571 related bugs, and changed shmem/locking to use apr API. Shared-mem
6572 is currently disabled, however, because of problems with graceful
6573 restarts. [Ronald Tschalär]
6575 *) Fix corruption of IFS variable in --with-module= handling.
6576 Depending on the user's shell or customization thereof, there
6577 would be errors generating ap_config_auto.h later in the configure
6578 procedure. [Jeff Trawick]
6580 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
6581 isn't used (as in 1.3), except that on Unix it is now logged via
6582 ap_log_rerror() instead of by the child having STDERR_FILENO refer
6583 to the error log. [Greg Ames, Jeff Trawick]
6585 *) Add '-D' argument processing for run time configuration defines.
6588 *) Organize http_main.c as independent code, such that no code or
6589 global data is exported from it. WIN32 will dynamically link it
6590 to the server core, so this will prevent mutual dependency.
6593 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
6594 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
6597 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
6598 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
6600 *) Add mod_charset_lite for configuring character set translation.
6603 *) Add '-n' option to htpasswd to make it print its user:pw record
6604 on stdout rather than having to frob a text file. [Ken Coar]
6606 *) Fix saferead. Basically, we flush the output buffer if a read on the
6610 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
6611 a conversion is single-byte only. [Jeff Trawick]
6613 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
6614 the BeOS 5.0 documentation says that shutdown doesn't work yet.
6617 *) Fix some minor errors where pid was being manipulated as an int
6618 instead of the portable pid_t. [Roy Fielding]
6620 *) Fix some error log prints that were printing the pointer to a
6621 structure rather than the pid within the structure.
6622 [Jeff Trawick, Roy Fielding]
6624 *) ab: Fix a command-line processing bug; track bad headers in
6625 err_response; support reading headers up to 2K.
6626 [Ask Bjoern Hansen <ask valueclick.com>]
6628 *) Fix ap_resolve_env() so that it handles new function added in a prior
6629 alpha (see "Added the capability to do ${ENVVAR} constructs in the
6630 config file.") as well as the constructs used by mod_rewrite.
6631 [Paul Reder <rederpj raleigh.ibm.com>]
6633 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
6635 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
6636 APR to perform translation, instead of accessing the hard-coded tables
6637 in 1.3's ebcdic.c. [Jeff Trawick]
6639 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
6642 *) Add the ability to hook into the config file reading phase. Basically
6643 if a directive is specified EXEC_ON_READ, then when that directive is
6644 read from the config file, the assocaited function is executed. This
6645 should only be used for those directives that must muck with HOW the
6646 server INTERPRETS the config. This should not be used for directives
6647 that re-order or replace items in the config tree. Those changes should
6648 be made in the pre-config step.
6651 *) Add mod_example to the build system.
6654 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
6655 byte character sets. [Jeff Trawick]
6657 *) Pick up various EBCDIC fixes from 1.3 (from Martin
6658 Kraemer and Oliver Reh originally according to the change log).
6661 *) Fix a couple of problems in RFC1413 support (controlled by the
6662 IdentityCheck directive). Apache did not build the request string
6663 properly and more importantly Apache would loop forever if the
6664 would-be ident server dropped the connection before sending a
6665 properly terminated response. [Jeff Trawick]
6667 *) apxs works in 2.0.
6670 *) Reliable piped logs work in 2.0.
6673 *) Introduce a hash table implementation into APR to be used for
6674 replacing tables and other random data structures in Apache.
6677 *) Add some more error reporting to htpasswd in the case of problems
6678 generating or accessing the temporary file. Also, pass in a
6679 buffer if the implementation knows how to use it (i.e., if L_tmpnam
6680 is defined). [Ken Coar]
6682 *) Configure creates config.nice now containing your configure
6683 options. Syntax: ./config.nice [--more-options]
6686 *) Fix various return code problems in APR on Win32. For most of
6687 these, APR was returning APR_EEXIST instead of GetLastError()/
6688 WSAGetLastError(). [Jeff Trawick]
6690 *) Make piped logs work again in version 2.0
6693 *) Add VPATH support to UNIX build system of Apache and APR.
6696 *) Fix ap_tokenize_to_argv to respect the const arguments that are
6700 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
6701 Patch submitted to author.
6704 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
6705 /sbin in PATH on FreeBSD (all submitted to rse previously)
6708 *) Fix building Pthread-based MPMs on OpenBSD
6709 [Sascha Schumann] PR#26
6711 *) Fix ap_readdir() problem on systems where d_name[] field in
6712 struct dirent is declared with only one byte. (This problem only
6713 affected multithreaded builds.) This caused a segfault during
6714 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
6715 least). [Jeff Trawick]
6717 *) Fix some make-portability problems on at least Tru64, Irix
6719 [Sascha Schumann] PR#18, PR#39
6721 *) Add ap_sigwait() to support old-style sigwait() on systems
6722 like OS/390 and UnixWare.
6725 *) Add POSIX-thread flags for more platforms.
6728 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
6729 (on Unix, at least) to handle resolver errors. Fix a bug in
6730 the definition of APR_ENOMEM so that ap_strerror() can spit
6731 out the correct error message for it.
6734 Changes with Apache 2.0a3
6736 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
6739 *) API: *HOOK* macros now have an AP_ prefix
6742 *) Win32: Eliminate redundant calls to initialize winsock.
6743 [Tim Costello <timcostello ozemail.com.au>]
6745 *) Fix bugs initializing ungetchar for pipes.
6746 [Chia-liang Kao <clkao CirX.ORG>]
6748 *) The ab program in the src/support directory is now portable using
6752 *) Support directory is being compiled when the server is built
6755 *) The configure option --with-program-name has been added to allow
6756 developers to rename the executable at configure time. This also
6757 changes the name of the config files to match the executable's name.
6760 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
6761 containing version numbers. [Martin Pool]
6763 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
6764 Unix; access_log and error_log now created with these perms; non-
6765 Unix is unaffected [Jeff Trawick]
6767 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
6768 Replaced more magic numbers with MD5_DIGESTSIZE.
6769 [William Rowe, Roy Fielding]
6771 *) Win32: Get mod_auth_digest compiling and added to the Windows
6772 build environment. Not tested and I'd be suprised if it
6773 actually works. [Bill Stoddard]
6775 *) Revamp the Win32 make environment. Makefiles have been removed and
6776 Apache.dsw created to bring together all the pieces. Create new file
6777 os/win32/BaseAddr.ref to define module base addresses (to prevent
6778 dll relocation at start-up).
6779 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
6781 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
6782 of the \015, \012, and \015\012 constants with macros.
6785 *) Add ap_xlate_open() et al for translation of text between different
6786 character sets. The initial implementation requires iconv().
6789 *) More FAQs and answers from comp.infosystems.www.servers.unix.
6790 [Joshua Slive <slive finance.commerce.ubc.ca>]
6792 *) CGI output is being timed out now.
6795 *) Fix the problem with dieing quietly. dupfile now takes a pool which
6796 is used by the new apr file. There is no reason to create a new file
6797 with the same lifetime as the original file.
6800 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
6801 module base addresses. This will help shooting seg faults
6802 in the field. [William Rowe <wrowe lnd.com>]
6804 *) Update Apache on Windows documentation. Add new document
6805 describing how to compile Apache on Windows.
6806 [William Rowe <wrowe lnd.com>]
6808 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
6809 microseconds instead of seconds. Some storage leaks and other
6810 minor bugs in related code were fixed. [Jeff Trawick]
6812 *) Win32: First cut at getting mod_isapi working under 2.0
6813 [William Rowe <wrowe lnd.com>]
6815 *) First stab at getting mod_auth_digest working under 2.0
6816 quick change summary:
6817 - moved the random byte generation (ap_generate_random_bytes) into APR
6818 - now uses ap_time_t
6819 - compiles and runs on linux
6821 [Brian Martin <bmartin penguincomputing.com>]
6823 *) Win32: Move the space stripping of physical service names
6824 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
6825 unresolved symbol. Add dependency checking to the
6826 CreateService call to ensure TCPIP and AFP (winsock) is started
6828 [William Rowe <wrowe lnd.com>]
6830 *) Win32: Add code to perform latebinding on functions that may
6831 not exist on all levels of Windows where Apache runs. This
6832 is needed to allow Apache to start-up on Win95/98. All calls
6833 to non portable functions should be protected with
6834 ap_oslevel checks to prevent runtime segfaults.
6835 [William Rowe <wrowe lnd.com>]
6837 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
6839 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
6841 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
6842 This addresses PR 1623. Still need to address timing out runaway
6843 CGI scripts. [Bill Stoddard]
6845 *) Win32: Make ap_stat Windows 95/98 friendly
6846 [William Rowe <wrowe lnd.com>]
6848 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
6849 always fail. Need to initialise the dwOSVersionInfoSize member of the
6850 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
6853 The patch also enhances ap_get_oslevel (and the associated enum) to
6854 handle selected service packs for NT4, and adds recognition for
6855 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
6856 we can use ReadFileScatter and WriteFileGather in readwrite.c.
6857 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
6859 *) Get mod_rewrite building and running, and mod_status building for Win NT
6860 [Allan Edwards <ake raleigh.ibm.com>]
6862 *) Patch to port mod_auth_db to the 2.0 api and also to support
6863 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
6864 2.7.7. It should work with version 1 as well but I haven't tested it.
6865 [Brian Martin <bmartin penguincomputing.com>]
6867 *) Get APR DSO code working under Windows. Includes cross platform
6869 [<Tim.Costello BTFinancialgroup.com>]
6871 *) Fix some of the Windows APR time functions.
6874 *) FAQ changes related to tidying up historical documents on the web site.
6875 [Joshua Slive <slive finance.commerce.ubc.ca>]
6877 *) Move Windows DSO code into APR.
6880 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
6881 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
6882 at build time. At this point, the server will not compile on Windows because
6883 of the recent DSO commits. Fixing those next.
6884 [Bill Rowe & Bill Stoddard]
6886 *) Added error checking for file I/O APR routines.
6887 [Jon Travis <jtravis covalent.net>]
6889 *) APR: Don't use the values of resolver error codes for the
6890 corresponding APR error codes. On Unix and Win32, return the
6891 proper APR error code after a resolver error. [Jeff Trawick]
6893 Changes with Apache 2.0a2
6895 *) Renamed the executable back to httpd on all platforms other
6899 *) Allow BeOS to survive restarts, log properly and a few
6900 small things it had problems with due to the way it setup
6901 users and groups. [David Reid]
6903 *) Get mod_rewrite working with APR locks
6904 [Paul Reder <rederpj raleigh.ibm.com>]
6906 *) Actually remove the sempahore when the lock cleanup routine
6907 is called on BeOS. [David Reid]
6909 *) Clear hook registrations between reads of the config file.
6910 When DSOs are unloaded and re-loaded the old hook pointers may
6911 no longer be valid. This fix eliminates potential segfaults.
6912 [Allan Edwards <ake raleigh.ibm.com>]
6914 *) Fix a problem with Sigfunc not being defined or bypassed
6915 if sigaction() wasn't found. [Jim Jagielski]
6917 *) Fix the locking mechanism on BSD variants. They now use fcntl
6918 locks. This allows the server to start and serve pages.
6921 *) First cut at getting the Win32 installer to work
6922 [William Rowe <wrowe lnd.com>]
6924 *) Get htpasswd compiling under Windows
6925 [William Rowe <wrowe lnd.com>]
6927 *) Change the log message for a bind() failure to show the
6928 interface and port number. [Jeff Trawick]
6930 *) Import the documentation from 1.3.12 and bring parts of it
6931 up-to-date with respect to the changes that have occurred
6935 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
6936 now logged correctly on BeOS.
6939 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
6940 Makefile.win includes the same user interface as the old
6942 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
6944 *) Win32 exec now uses COMSPEC environment string for command
6945 shell path resolution.
6946 [William Rowe <wrowe lnd.com>] PR#3715
6948 *) Win32: ap_connect() was not returning correct error condition
6950 [Allen Prescott <allen clanprescott.com>]
6952 *) Win32: ap_open() was broken on Win9x because an NT-specific
6953 flag was passed to CreateFile. ap_puts() added an unnecessary
6955 [Jeff Trawick <trawick us.ibm.com>]
6957 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
6958 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
6959 confusing ee/et name and made all extensions language/dialect
6960 rather than country reflecting. Changed example files to
6961 explicit reflect the ISO charset and added a few common
6962 ones to the example config [dirkx]
6964 *) Extend external module capability. To use this, you call
6965 configure with --with-module=path/to/mod1,path/to/mod2,etc.
6968 *) Backported the various "default charset" fixes from 1.3.12,
6969 including the AddDefaultCharset directive. [Jim Jagielski]
6971 *) Added the capability to do ${ENVVAR} constructs in the
6972 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
6973 it does this on a line by line basis; i.e. if the envvar
6974 expands to something with spaces you have to protect it
6975 by adding quotes around it (Unless of course you expect it
6976 to contains more than one argument. Alternatively you
6977 can compile it on a per token basis; which is what people
6978 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
6979 hampers fancier hacks.
6980 [Dirk-Willem van Gulik]
6982 *) Changed the 'ErrorDocument' syntax in that it NO longer
6983 supports the asymetric
6985 ErrorDocument 301 "Some message
6987 Note the opening " quote, without a closing quote. It now
6988 has either the following syntaxes
6990 ErrorDocument XXX /local/uri
6991 ErrorDocument XXX http://valid/url
6992 ErrorDocument XXX "Some Message"
6994 The recognition heuristic is: if it has a space it
6995 is a message. If it has no spaces and starts with a /
6996 or is a valid URL then treat it that way. Otherwise it
6997 is assumed to be a message.
6999 This breaks backward compatibility but makes live a hell
7000 of a lot easier for GUI's and config file parsers.
7001 [Dirk-Willem van Gulik]
7003 *) Changed 'CacheNegotiatedDocs' from its present/not-present
7004 syntax into a 'on' or 'off' syntax. As it currently is the
7005 only non nesting token which uses NO_ARGS and thus is an
7006 absolute pain for any config interface automation. This
7007 breaks backward compatibility. [Dirk-Willem van Gulik]
7009 *) Add ability to add external modules to the build process. This is
7010 done with --with-module=/path/to/module. Modules can only be added
7011 as static modules at this point.
7014 Changes with Apache 2.0a1
7016 *) Fix FreeBSD 3.3 core dump.
7017 Basically, ap_initialize() needs to get called before
7018 create_process(), since create_process() passes op_on structure
7019 to semop() to get a lock, but op_on isn't initialized until
7020 ap_initialize() calls setup_lock(). Here is a slight
7021 rearrangement to main() which calls ap_initialize() earlier...
7022 [Jeff Trawick <trawick us.ibm.com>]
7024 *) Enable Apache to use sendfile/TransmitFile API
7025 [Bill Stoddard, David Reid, Paul Reder]
7027 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
7031 *) Make file I/O and network I/O writev/sendv APIs consistent.
7032 Eliminate use of ap_iovec_t and use Posix struct iovec.
7033 Use seperate variable on ap_writev to set the number of iovecs
7034 passed in and number of bytes written.
7037 *) Adapt file iol to use APR functions. Replaced ap_open_file()
7038 with ap_create_file_iol(). ap_create_file_iol() requires that
7039 the file be opened prior to the call using ap_open().
7042 *) Port mod_include and mod_cgi to 2.0
7043 [Paul Reder, Bill Stoddard]
7045 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
7046 bytes_read/bytes_written is always valid (never -1). Plus
7047 some fixes to buff.c to correct problems introduced by the
7048 errno => ap_status_t changes a while back. Plus a fix to
7049 chunked encoding introduced right at the beginning of 2.0.
7052 *) Revamped UNIX build system to use autoconf and libtool.
7053 [Manoj Kasichainula, Sascha Schumann]
7055 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
7057 *) SECURITY: More rigorous checking of Host: headers to fix security
7058 problems with mass name-based virtual hosting (whether using mod_rewrite
7059 or mod_vhost_alias).
7060 [Ben Hyde, Tony Finch]
7062 *) Add back support for UseCanonicalName in <Directory> containers.
7063 [Manoj Kasichainula]
7065 *) Added APLOG_STARTUP log type. This allows us to write an error
7066 message without any of the date and time information. As a part
7067 of this change, I also removed all of the calls to fprintf(stderr
7068 and replaced them with calls to ap_log_error using APLOG_STARTUP
7069 writing to stderr is no longer portable, because we don't direct
7070 stderr to the error log on all platforms.
7073 *) Convert error logging functions to take errno as an argument.
7074 This makes our error logs more portable, because some Windows API's
7075 don't set errno. This change allows us to still output a valid
7076 message on all of our platforms.
7079 *) mod_mime_magic runs in 2.0-dev now.
7080 [Paul Reder <rederpj raleigh.ibm.com>]
7082 *) sendfile has been added to APR.
7083 [John Zedlewski <zedlwski Princeton.EDU>]
7085 *) buff.c has been converted to no longer use errno.
7086 [Manoj Kasichainula]
7088 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
7089 interface adaption to APR functions did it. [Martin Kraemer]
7091 *) Support DSOs properly on 32-bit HP-UX 11.0
7092 [Dilip Khandekar <dilip cup.hp.com>]
7094 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
7095 [Ralf S. Engelschall]
7097 *) Cleaned APR build environment integration and bootstrap APR
7098 automatically for developers from src/Configure.
7099 [Ralf S. Engelschall]
7101 *) Fixed building of src/support/htpasswd.c
7102 [Ralf S. Engelschall]
7104 *) When generating the Location: header, mod_speling forgot
7105 to escape the spelling-fixed uri. (Forw-Port from 1.3)
7108 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
7110 *) Change all pools to APR contexts. This is the first step to
7111 incorporating APR into Apache. [Ryan Bloom]
7113 *) Move "handler not found" warning message to below the check
7114 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
7115 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
7117 *) Support line-continuation feature in config.option file and
7118 allow the loading of multiple option sections at once via
7119 ``--with-option=<section1>,<section2>,...''
7120 [Ralf S. Engelschall]
7122 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
7124 Changes with Apache MPM
7126 *) Use asynchronous AcceptEx() and a completion port to accept and
7127 dispatch connections to threads in Windows NT/2000.
7130 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
7133 *) Implement the APACI --with-option facility
7134 (per default used the config.option file).
7135 [Ralf S. Engelschall]
7137 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
7139 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
7140 Replace pre_connection module call with a register_hook call and
7141 implement pre_connection as a hook. The intent is that these hooks will
7142 be extended to allow Apache to be multi-protocol, and also to allow the
7143 calling order to be specified on a per-hook/per-module basis.
7146 *) Implement mpm_* methods as "modules". Each method gets its own
7147 subdir in src/modules (eg: src/modules/prefork). Selection
7148 of method uses Rule MPM_METHOD. [Jim Jagielski]
7150 *) Port the hybrid server from the apache-apr repository as
7151 mpm_mpmt_pthread. [Manoj Kasichainula]
7153 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
7154 amongst the unix MPMs.
7156 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
7157 signal handling for the new world order. [Dean Gaudet]
7159 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
7160 of alloc.c for now. [Dean Gaudet]
7162 *) Handle partial large writes correctly. [Ben Laurie]
7164 *) Eliminate conn_rec's pointer to server. All it knows is the base server
7165 based on IP/port. [Ben Laurie]
7167 *) Port a bunch of modules to the new module structure.
7168 ["Michael H. Voase" <mvoase midcoast.com.au>]
7170 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
7172 *) Basic restructuring to introduce the MPM concept; includes various
7173 changes to the module API... better described by
7174 docs/initial_blurb.txt. [Dean Gaudet]
7176 Changes with Apache pthreads
7178 *) New buff option added: BO_TIMEOUT. It describes the timeout for
7179 buff operations (generally over a network).
7180 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
7182 *) Created http_accept abstraction. Added 4 new functions (not exported):
7183 init_accept(), begin_accepting_requests(), get_request(),
7184 stop_accepting_requests() [Bill Stoddard]
7186 *) Fix to ap_rprintf call that allows mod_info to work properly.
7187 [James Morris <jmorris intercode.com.au>]
7189 *) user and ap_auth_type fields were moved from connection_rec to
7190 request_rec. [Ryan Bloom]
7192 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
7193 needed in a threaded server.
7195 *) Initial pthread implementation from from Dean's apache-nspr code.
7196 [Bill Stoddard, Ryan Bloom]
7199 Changes with Apache 1.3.9
7201 *) Remove bogus error message when a redirect doesn't set Location.
7202 Instead, use an empty string to avoid coredump if the error message
7203 was supposed to include a location. [Roy Fielding]
7205 *) Don't allow configure to include mod_auth_digest unless it is
7206 explicitly requested, even if the user asked for all modules.
7209 *) Translate module names to dll names for OS/2 so that they are no more
7210 than 8 characters long and have an extension of "dll" instead of "so".
7213 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
7214 Fix test-compile check to check for randbyte instead of trand32.
7215 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
7216 and tweak to make Amaya happier. [Ronald Tschalär]
7218 *) Ensure that the installed expat include files are world readable,
7219 just like the other header files. [Martin Kraemer]
7221 *) Fixed generated AddModule adjustments in APACI's `configure' script
7222 in order to allow (new) modules like mod_vhost_alias to be handled
7223 correctly (which was touched by the adjustments for mod_alias).
7224 [Ralf S. Engelschall]
7226 *) For binary builds, add -R flag to apachectl to work around the lack of
7227 an absolute path to the ./libexec directory where the libhttp.ep file
7228 is needed for SHARED_CORE architectures. [Randy Terbush]
7230 *) WIN32: Create the CGI script process as DETACHED. This may solve the
7231 problem observed by some Win95/98 users where they get CGI script
7232 output sent to the console. [Bill Stoddard]
7234 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
7235 routines are now called ap_base64* and are 'plain' (i.e., no
7236 pool access or anything clever). Inside util.c the routines acting
7237 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
7238 The oddly named ap_uuencode(), ap_uudecode() are kept around for
7239 now but deprecated. [dirkx]
7241 *) Clean up the base64 and SHA1 additions and make sure they are
7242 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
7243 files. [Roy Fielding]
7245 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
7246 checking. Allow compiling on VS 6.0. [Randy Terbush]
7248 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
7250 *) Use TestCompile to search for the truerand library (rather than blindly
7251 assuming its existence). If it is not found, complain (but do not
7252 exit - yet). [Martin Kraemer]
7254 *) We forgot to add the new exported function names to
7255 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
7257 *) Add description of -T command-line option to usage().
7258 [Ralf S. Engelschall]
7260 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
7261 searched only AFTER libap has been searched, because libap needs
7262 some symbols from libos. [Martin Kraemer]
7264 *) Fix conflict with original mod_digest related to the symbol of the
7265 module dispatch list (which has to be unique for DSO and follow the
7266 usual conventions for the installation procedure).
7267 [Ralf S. Engelschall]
7269 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
7270 for other platforms as well. [Martin Kraemer]
7272 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
7273 types by AP_LONG and replace reference to renamed variable 'ubuf'
7274 by 'buffer'. [Martin Kraemer]
7276 Changes with Apache 1.3.8 [not released]
7278 *) Flush the output buffer immediately after sending an error or redirect
7279 response, since the result may be needed by the client to abort a
7280 long data transfer or restart a series of pipelined requests.
7281 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
7283 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
7284 [Ian Turner <iant sequent.com>] PR#4735
7286 *) Local struct mmap in http_core.c conflicted with system structure
7287 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
7289 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
7290 [Ronald Tschalär <ronald innovation.ch>]
7292 *) Fix a memory leak where the module counts were getting messed
7293 up across restarts. [David Harris <dharris drh.net>]
7295 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
7296 properly in mod_access.
7297 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
7299 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
7300 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
7302 *) PORT: Support for compaq/tandem/com.
7303 [Michael Ottati <michael.ottati compaq.com>, dirkx]
7305 *) Added SHA1 password encryption support to easy migration from
7306 Netscape servers. See support/SHA1 for more information.
7307 Caused the separation of ap_md5.c into md5, sha1 and a general
7308 ap_checkpass.c with just a validate_passwd routine. Added a
7309 couple of flags to support/htpasswd. Some reuse of the to64()
7310 function; hence renamed to ap_to64().
7311 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
7313 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
7314 with ASCII/EBCDIC conversions in "ident" query.
7315 [David McCreedy <McCreedy us.ibm.com>]
7317 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
7318 Change "Power Macintosh" to Power* so if uname prints "Power Book"
7319 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
7321 *) Fix SIGSEGV on some systems because the Vary fix below included
7322 a call to table_do with a variable argument list that was not
7323 NULL terminated. Replaced with better implementation. [Roy Fielding]
7325 Changes with Apache 1.3.7 [not released]
7327 *) The "Vary" response header field is now sanitised right before
7328 the header is sent back to the client. Multiple "Vary" fields
7329 are combined, and duplicate tokens (e.g., "Vary: host, host" or
7330 "Vary: host, negotiate, host, accept-language") are reduced to
7331 single instances. This is a better solution than the force-no-vary
7332 one (which is still valid for clients that can't cope with Vary
7333 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
7335 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
7337 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
7338 least on Linux and FreeBSD for now.
7341 *) Win32: More apache -k restart work. Restarts are now honored
7342 immediately and connections in the listen queue are -not- lost.
7343 This is made possible by the use of the WSADuplicateSocket()
7344 call. The listeners are opened in the parent, duplicated, then
7345 the duplicates are passed to the child. The original listen sockets
7346 are not closed by the parent across a restart, thus the listen queue

7350 *) Fix handling of case when a client has sent "Expect: 100-continue"
7351 and we are going to respond with an error, but get stuck waiting to

7355 *) Fix 'configure' to work correctly with SysV-based versions of
7356 'tr' (consistent with Configure's use as well). [Jim Jagielski]
7358 *) apxs: Add "-S var=val" option which allows for override of CFG_*
7359 built-in values. Add "-e" option which works like -i but doesn't
7360 install the DSO; useful for editing httpd.conf with apxs. Fix
7361 editing code so that multiple invocations of apxs -a will not
7362 create duplicate LoadModule/AddModule entries; apxs can now be
7363 used to re- enable/disable a module. [Wilfredo Sanchez]
7365 *) Win32: Update the server to use Winsock 2. Specifically, link with
7366 ws2_32.lib rather than wsock32.lib. This gives us access to
7367 WSADuplcateSocket() in addition to some other enhanced comm APIs.
7368 Win 95 users may need to update their TCP/IP stack to pick up
7369 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
7370 [Bill Stoddard <stoddard raleigh.ibm.com>]
7372 *) Win32: Redirect CGI script stderr (script debug info) into the

7396 *) Fix apxs build issues on AIX
7397 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
7399 *) DocumentRoot Checking: Under previous versions, when Apache
7400 first started up, it used to do a stat of each DocumentRoot to
7401 see if it existed and was a directory. If not, then an error
7402 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
7403 does not exist, you will get error messages in error_log. If
7404 the '-t' command line option is used (to check the configuration)
7405 the check of DocumentRoot IS performed. An additional command
7406 line option, '-T', has been added if you want to avoid the
7407 DocumentRoot check even when checking the configuration.
7410 *) Win32: The query switch "apache -S" didn't exit after showing the
7411 vhost settings. That was inconsistent with the other query functions.
7412 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
7414 *) Win32: Changed behaviour of apache -k restart.
7415 Previously, the server would drain all connections in the stack's
7416 listen queue before honoring the restart. On a busy server, this
7417 could take hours. Now, a restart is honored almost immediately.
7418 All connections in Apache's queues are handled but connections in
7419 the stack's listen queue are discarded. Restart triggered by
7420 MaxRequestPerChild is unchanged.
7421 [Bill Stoddard <stoddard raleigh.ibm.com>]
7423 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
7424 the accept loop. Good for a 5% performance boost. Cleaned up

7448 never accepted into any standard, and it opens up certain DoS
7449 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
7451 *) TestCompile updated. We can now run programs and output the
7452 results during the Configure process. [ Jim Jagielski]
7454 *) The source is now quad (long long) aware as needed. Specifically,
7455 the Configure process determines the correct size of off_t and
7456 *void. When the OS/platform/compiler supports quads, ap_snprintf()
7457 provides for the 'q' format qualifier (if quads are not available,
7458 'q' is silently "demoted" to long). [Jim Jagielski]
7460 *) When the username or password fed to htpasswd is too long, include the
7461 size limit in the error message. Also report illegal characters
7462 (currently only ':') in the username. Add the size restrictions
7463 to the man page. [Ken Coar]

7482 ap_regexec(). This solves problems with DSO modules which use the regex
7483 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]

7744 DefaultType gargle/blurb
7746 Additionally, add the Content-Encoding: header to FTP proxy replies
7747 when the encoding is defined (by the AddEncoding directive).
7748 Because it was missing, it was almost impossible to browse compressed

7858 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
7859 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
7860 possible buffer overflows. [Ralf S. Engelschall]
7862 *) Remove no longer used non-API function ap_single_module_init().
7863 [Ralf S. Engelschall]
7865 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
7868 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
7869 to make platform installations easier. [Wilfredo Sanchez]
7871 *) In configure, do not append the target name to the directory path if
7872 the path already contains "apache". [Ralf S. Engelschall]
7874 *) SIGPIPE is now ignored by the server core. The request write routines
7875 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
7876 correctly check for output errors and mark the connection as aborted.
7877 Replaced many direct (unchecked) calls to ap_b* routines with the
7878 analogous ap_r* calls. [Roy Fielding]
7880 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
7881 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
7882 Furthermore map lookups for non-existent keys are now cached as well.
7883 Additionally "txt" maps are now parsed with simple string functions
7884 instead of using ap_pregcomp(). As a side effect a bug that prevented
7885 the usage of keys containing the "," character was fixed.
7886 The changes drastically improve the performance when large rewrite maps
7888 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
7890 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
7891 other than GET, and const'd the definition of method in request_rec.
7894 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
7896 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
7897 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
7899 *) Add %V to mod_log_config, this logs the hostname according to the
7900 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
7901 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
7903 *) Add support for \n and \t to mod_log_config, can be used to produce
7904 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
7906 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
7908 *) Added informative error messages for failed munmap() and fseek() calls
7909 in http_core.c. [John Bley, Roy Fielding]
7911 *) Added some informative error messages for some failed malloc()
7912 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
7914 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
7915 is removed. This allows <Directory proxy:*> directives to work and
7916 prevents invalid requests from killing the process.
7917 [Brian Havard <brianh kheldar.apana.org.au>]
7919 *) Reorganised FAQ document.
7920 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497
7922 *) src/support/: The ApacheBench benchmark program was overhauled by
7923 David N. Welton: you can now have it generate an HTML TABLE, presumably
7924 for integration into other HTML sources. David updated the ab man page
7925 as well and added some missing descriptions. Thanks!
7926 [David N. Welton <davidw prosa.it>]
7928 *) Win32: The filename validity checker now allows filenames containing
7929 characters in the range 0x80 to 0xff (for example accented characters).
7930 [Paul Sutton] PR#3890
7932 *) Added conditional logging based upon environment variables to
7933 mod_log_config. mod_log_referer and mod_log_agent
7934 are now deprecated. [Ken Coar]
7936 *) Allow apache acting as a proxy server to relay the real
7937 reason of a failure to a client rather than the "internal
7938 server error" it does currently. The general exposure mechanism
7939 can be triggered by any module by setting the "verbose-error-to"
7940 note to "*"; this allows more than just proxy errors to be exposed.
7941 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
7943 *) Moved man pages for ab and apachectrl to section 8.
7944 [Wilfredo Sanchez, Roy Fielding]
7946 *) Added -S option to install.sh so that options can be passed to
7947 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
7949 *) Tweak modules Makefile generated by Configure so that it handles
7950 the test case of no modules being selected. [<chaz reliant.com>]
7952 *) Added a <LimitExcept method ...> sectioning directive that allows
7953 the user to assign authentication control to any HTTP method that
7954 is *not* given in the argument list; i.e., the logical negation
7955 of the <Limit> directive. This is particularly useful for controlling
7956 access on methods unknown to the Apache core, but perhaps known by
7957 some module or CGI script. [Roy Fielding, Tony Finch]
7959 *) Prevent apachectl from complaining if the PIDFILE exists but
7960 does not contain a process id, as might occur if the server is
7961 being rapidly restarted. [Wilfredo Sanchez]
7963 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
7965 *) Entity tag comparisons for If-Match and If-None-Match were not being
7966 performed correctly -- weak tags might cause false positives. Also,
7967 strong comparison wasn't properly enforced in all cases.
7968 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
7970 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
7973 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
7974 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
7976 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
7977 to util.c for parsing an HTTP header field value to extract the next
7978 list item, taking into account the possible presence of nested comments,
7979 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
7980 insignificant whitespace and lowercases non-quoted tokens.
7981 [Roy Fielding] PR#2065
7983 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
7984 code different from 500. This allows the proxy to, e.g., return
7985 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
7987 *) Fix ordering of language variants for the case where the traditional
7988 negotiation algorithm is being used with multiple language variants
7989 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
7991 *) Do not round the TCN quality calculation to 5 decimal places,
7992 unlike RFC 2296, because the calculation might need 12 decimal places
7993 to get the right result. [Roy Fielding]
7995 *) Remove unused code to disable transparent negotiation when
7996 negotiating on encoding only, as we now handle encoding too
7997 (though this is nonstandard for TCN), remove charset=ISO-8859-1
7998 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
7999 some debugging statements within mod_negotiation. [Koen Holtman]
8001 *) Fixed a rare memory corruption possibility in mod_dir if the index
8002 file is negotiable and no acceptable variant can be found.
8003 [Dean Gaudet, Roy Fielding, Martin Kraemer]
8005 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
8006 searching the Win32 registry for script interpreters.
8009 *) Win32: The compiled-in default filename for the error log is now
8010 error.log, which matches the default in the distributed httpd.conf.
8013 *) Win32: Any error messages from -i or -u command line options are now
8014 displayed on the console output rather than sent to the error log.
8015 Also the "Running Apache..." message is not output unless Apache is
8016 going to serve requests. [Paul Sutton]
8018 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
8019 and use a private significator ('$apr1$') to mark passwords as
8020 being smashed with our own algorithm. Also abstract the password
8021 checking into a new ap_validate_password() routine. [Ken Coar]
8023 *) Win32: The filename validity checker now allows "COM" but refuses
8024 access to "COM1" through "COM4". This allows filenames such
8025 as "com.name" to be served. [Paul Sutton] PR#3769.
8027 *) BS2000: Adapt to the new ufork() system call interface which will
8028 make subtasking easier on the OSD/POSIX mainframe environment.
8031 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
8032 ap_compat.h. [David White <david persimmon.com>] PR#3725
8034 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
8035 use `.db' instead of `.pag' not only for FreeBSD, but also when
8036 the NDBM library looks like Berkeley-DB based.
8037 [Ralf S. Engelschall] PR#3773
8039 *) Add ability to handle DES or MD5 authentication passwords.
8040 [Ryan Bloom <rbb Raleigh.IBM.Com>]
8042 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
8044 *) SECURITY: Avoid some buffer overflow problems when escaping
8045 quoted strings. (This overflow was on the heap and we believe
8046 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
8048 *) Let src/Configure be aware of CFLAGS options starting with plus
8049 signs as it's the case for the HP/UX compiler.
8050 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
8052 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
8053 and check to see if the tar we wind up with supports '-h'.
8054 [Jim Jagielski] PR#3671
8056 *) A consistent and conservative style for all shell scripts has been
8057 implemented. Basically, all shell string tests use the traditional
8058 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
8059 to protect against bare null variable strings (ie: wrapping both
8060 sides with double quotes and prepending 'x'). 'x' was chosen
8061 because it's more universal and hopefully easier for old shell
8062 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
8065 *) The status module now prints out both the main server generation as
8066 well as the generation of each process. Also, the vhost info is
8067 printed with '?notable'. [Jim Jagielski]
8069 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
8070 and this makes its functions available to things in src/support.
8073 Changes with Apache 1.3.4
8075 *) Renamed macros status_drops_connection to ap_status_drops_connection
8076 and vestigial scan_script_header to ap_scan_script_header_err,
8077 mostly for aesthetic reasons. [Roy Fielding]
8079 *) The query switch "httpd -S" didn't exit after showing the
8080 vhost settings. That was inconsistent with the other query functions.
8083 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
8084 filename to the end of the STANDARD_MODULE_STUFF. Its
8085 presence at the beginning prevented reporting of the filename
8086 for modules compiled before 1 January 1999. [Ken Coar]
8088 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
8089 to detect and prevent access to special DOS device file names.
8090 [Paul Sutton, Ken Parzygnat]
8092 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
8093 and Makefile_win32_debug.txt (debug build) that work on Win95.
8094 Run each of the following from the src directory:
8095 nmake /f Makefile_win32.txt # compiles normal build
8096 nmake /f Makefile_win32.txt install # compiles and installs
8097 nmake /f Makefile_win32.txt clean # removes compiled junk
8098 nmake /f Makefile_win32_debug.txt # compiles debug build
8099 nmake /f Makefile_win32_debug.txt install
8100 nmake /f Makefile_win32_debug.txt clean
8103 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
8104 to build binary distributions. [Lars Eilebrecht]
8106 *) IndexOptions SuppressColumnSorting only turned off making
8107 the column headers anchors; you could still change the display
8108 order by manually adding a '?N=A' or similar query string to the
8109 URL. Now SuppressColumnSorting locks in the sort order so
8110 it can't be overridden this way. [Ken Coar]
8112 *) Added IndexOrderDefault directive to supply a default sort order
8113 for FancyIndexed directory listings. [Ken Coar] PR#1699
8115 *) Change the ap_assert macro to a variant that works on all platforms.
8116 [Richard Prinz <richard.prinz cso.net>] PR#2575
8118 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
8119 search for an underscore on dlsym() (as it's already the case
8120 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
8122 *) Small fix for mod_env.html: The module was documented as to be _not_
8123 compiled into Apache per default, although it _IS_ compiled into
8124 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
8126 *) Instead of fixing a bug in the generation procedure for config.status (a
8127 backslash was missing) we remove the bug together with it's complete
8128 context because the special cases of the past can now no longer occur
8129 because of the recent magic for the --with-layout default.
8130 [Ralf S. Engelschall] PR#3590
8132 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
8133 making sure the src/support/ tools are _forced_ to be build last (they
8134 depend on other libraries).
8135 [Markus Theissinger <markus.theissinger gmx.de>]
8137 *) Fix installation procedure: Now that os-inline.c is actually used (a
8138 recently fixed bug prevented this) we need to also install os-include.c
8139 in addition to os.h into the PREFIX/include/ location or building of
8140 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
8142 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
8143 allow us to distinguish between a garbled DSO (or even a file which isn't
8144 an Apache module DSO at all) and a DSO which doesn't match the current
8145 Apache API. [Ralf S. Engelschall] PR#3152
8147 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
8148 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
8149 match case insensitive (this especially avoids nasty patterns like
8150 `[tT][eE][sS][tT]'). Second two additional internal map functions
8151 `escape' and `unescape' were added which can be used to escape/unescape
8152 to/from hex-encodings in URLs parts (this is especially useful in
8153 combination with map lookups).
8154 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
8156 *) Renamed the macro escape_uri() to ap_escape_uri() which was
8157 forgotten (because it was a macro) in the symbol renaming process.
8158 [Ralf S. Engelschall]
8160 *) Fix some inconsistencies related to the scopes of directives. The only
8161 user visible change is that the directives `UseCanonicalName' and
8162 `ContentDigest' now use the (more correct) `Options' scope instead of
8163 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
8165 *) Using DSO, the Server token was being mangled. Specifically, the
8166 module's token was being added first before the Apache token. This
8167 has been fixed. [Jim Jagielski]
8169 *) Major overhaul of mod_negotiation.c, part 2.
8170 - properly handle "identity" within Accept-Encoding.
8171 - allow encoded variants in RVSA negotiation and let them appear in
8172 the Alternates field using the non-standard "encoding" tag-list.
8173 - fixed both negotiation algorithms so that an explicitly accepted
8174 encoding is preferred over no encoding if "identity" is not
8175 included within Accept-Encoding.
8176 - added ap_array_pstrcat() to alloc.c for efficient concatenation
8177 of large substring sequences.
8178 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
8181 *) Major overhaul of mod_negotiation.c, part 1.
8182 - cleanups to mod_negotiation comments and code structure
8183 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
8184 support for everything in the upcoming HTTP/1.1
8185 revision (draft-ietf-http-v11-spec-rev-06.txt).
8186 - language tag matching also handles tags with more than 2
8188 - empty Accept, Accept-Language, Accept-Charset headers are
8189 processed correctly; previously an empty header would make all
8190 values acceptable instead of unacceptable.
8191 - allowed for q values in Accept-Encoding
8192 - added support for transparent content negotiation (rfc2295 and
8193 rfc2296) (though we do not implement all features in these drafts,
8194 e.g. no feature negotiation). Removed old experimental version.
8195 - implemented 'structured entity tags' for better cache correctness
8196 (structured entity tags ensure that caches which can deal with Vary
8197 will (eventually) be updated if the set of variants on the server
8199 - this involved adding a vlist_validator element to request_rec
8200 - this involved adding the ap_make_etag() function to the global API
8201 - modified guessing of charsets used by Apache negotiation algorithm
8202 to guess 'no charset' if the variant is not a text/* type
8203 - added code to sort multiviews variants into a canonical order so that
8204 negotiation results are consistent across backup/restores and mirrors
8205 - removed possibility of a type map file resolving to another type map
8206 file as its best variant
8207 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
8209 *) RFC2396 allows the syntax http://host:/path (with no port number)

8211 [David Kristol <dmk bell-labs.com>] PR#3530
8213 *) When modules update/modify the file name in the configfile_t structure,
8214 syntax errors will report the updated name, not the original one.
8215 [Fabien Coelho <coelho cri.ensmp.fr>] PR#3573
8217 *) Correct some filename case assumptions from WIN32 to
8218 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
8220 *) For %v log ServerName regardless of the UseCanonicalName
8221 setting (similarly for %p). [Dean Gaudet]
8223 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
8224 rather late (too late for some invocations of TestCompile).
8225 This improves the make environment available to TestCompile and
8226 the *.module scripts. [Martin Kraemer]
8228 *) The hashbang emulation code in ap_execve.c would interpret
8229 #!/hashbang/scripts correctly, but failed to fall back to a
8230 standard shell for scripts which did NOT start with #!
8231 Now SHELL_PATH is started in these cases. [Martin Kraemer]
8233 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
8236 *) Update APXS manual page: some -q option arguments were missing
8237 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
8239 *) Cleanup the command line options: `-?' was documented to show
8240 the usage list but does it with an error because `?' is not a valid
8241 command. OTOH a lot of users expect `-h' to print such a usage list and
8242 instead are annoyed for ages by our huge unreadable list of directives.
8243 So we now changed the command line options this way:
8245 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
8246 very similar to the popular linker option.
8248 Intent: while -l gives the small list of modules, -L now gives the
8249 large list of directives implemented by these modules. This is also
8250 consistent with -v (short version info) and -V (large version info).
8252 Intent: it's now the expected option ;-)
8253 The manual page was adjusted accordingly.
8254 [Ralf S. Engelschall] PR#2714
8256 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
8257 wasn't defined. [Rick Franchuk <rickf transpect.net>]
8259 *) Removed recently introduced bugs and disfigurements in APACI:
8260 o fixed argument line processing: using $args was broken: It was not
8261 initialized and using args="$args $apc_option" and even args="$args
8262 \"$apc_option\"" fails in the second processing round for any arguments
8263 containing whitespaces. The only correct way is to use the construct
8264 "$@" (but not possible here) or iterate _both_ times over the implicit
8265 argument line (no argument to for-loop) which is what we now use.
8266 o make --with-layout=Apache the default without creating
8267 redundancy (copying the --with-layout block in the argument parsing
8268 loop). We achieve this by using the "$@" construct together with the
8269 `set' command to prepend --with-layout=Apache to the command line in
8270 case --with-layout is not used.
8271 o fixed auto-suffix handling now that config.layout exists.
8272 Paths which are auto-suffixed are marked with a trailing plus sign in
8273 config.layout and every path now can be marked this way (not only the
8274 four paths for which we do it currently). Additionally the suffix is
8275 no longer a static one. Instead it's now `/<target>' where <target> is
8276 the argument of the --target option or per default `httpd'.
8277 o allow also tabs (and only spaces) where we match whitespaces
8278 o various fixes and cleanups related to used shell coding style
8279 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
8280 o trimmed output of --help to fit into 80 columns
8281 [Ralf S. Engelschall]
8283 *) Added two new core API functions, ap_single_module_configure() and
8284 ap_single_module_init(), which are now used by mod_so to configure a module
8285 after loading. [Ralf S. Engelschall]
8287 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
8288 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
8289 of ap_config.h to allow serialized accept for multiport listens.
8290 [Roy Fielding, Curt Sampson] PR#3120
8292 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
8293 of ap_config.h that would skip several defines if DEFAULT_GROUP
8294 was overridden. [Roy Fielding]
8296 *) PORT: The I86 version of DGUX has support for strncasecmp and
8297 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
8299 *) Fix ordering of definitions in ap_config.h so that ap_inline is
8300 defined before it might be used. [Victor Khimenko]
8302 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
8303 [Tom Serkowski <tks bsdi.com>] PR#3453
8305 *) Make generation of src/Configuration.apaci more robust: It failed to
8306 differenciate between modules when one module name was a postfix of
8307 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
8308 just XXX (think about totally non-standard names like "apache_ssl", too).
8309 [Ralf S. Engelschall] PR#3380
8311 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
8312 since 1.3b7) and make whitespace handling more robust (it failed horrible
8313 when whitespaces were present in the arguments of -D options).
8314 [Ralf S. Engelschall] PR#3240
8316 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
8317 creates an external package shadow tree in DIR before the local build
8318 shadow tree is generated under DIR. This way one can have the extracted
8319 Apache distribution tree read-only on NFS or CDROM and still build Apache
8320 from these sources. An automatically triggered VPATH-like mechanism is
8321 provided through the TOP variable, too.
8322 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez apple.com>]
8324 *) Fix negotiation so that a Vary response header is correctly
8325 generated when, for a particular dimension, variants only vary
8326 in having or not having a value for that dimension. [Paul Sutton]
8328 *) Fix negotiation so that we prefer an encoded variant over an
8329 unencoded variant if the user-agent explicitly says it can
8330 accept that encoding. Previously we always preferred the unencoded
8332 [Paul Ausbeck <paula alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
8334 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
8335 and the usage page was inconsistent with the functionality and manpage.
8336 [Ralf S. Engelschall]
8338 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
8339 They can occur multiple times and their arguments (`xxx') are passed AS
8340 IS to the compiler/linker command. [Ralf S. Engelschall]
8342 *) Fixed possible (but harmless in practice) bug in the DBM lookup
8343 procedure of mod_rewrite: very long keys were truncated.
8344 [Ralf S. Engelschall]
8346 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
8347 identifier, currently "Apache" and "GNU" are pre-defined in the file
8348 config.layout. Custom layouts are possible by using FILE:ID as the
8349 argument where the layout ID is taken from FILE.
8351 The config.layout file consists of <Layout ID>..</Layout> sections
8352 where inside those sections "path_variable: path_value" pairs can be
8353 specified. These lines are converted to path_variable='path_value'.
8355 *) Add a DefaultLanguage directive so that files missing a language
8356 extension (e.g., .fr, .de) can be labelled as being some other
8357 default language. DefaultLanguage can appear in <Directory> and
8358 <Files> containers as well as .htaccess files. [Paul Sutton]
8361 *) Fix TARGET configuration when configuring and installing using
8362 APACI configure. TARGET now defines the basename of the configuration
8363 file, startup script, manual page, etc. log_error_core() now reports
8364 the server binary name given by argv[0]. TARGET can now also be defined
8365 with --target=TARGET parameter passed to APACI configure.
8366 [Ralf Engelschall, Randy Terbush]
8368 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
8369 rather than OPT_INCLUDES [Rainer Schoepf <schoepf uni-mainz.de>]

8388 notice to the error log. It is not possible to send a 401 response
8389 and a redirect at the same time. [Lars Eilebrecht]
8391 *) Fallback to native compilers for IRIX-32 platform. It seems that
8392 a gcc 2.8.1 compiled apache is logging client addresses with all
8393 bits set (255.255.255.255). This is the second such problem caused
8394 by gcc 2.8.1 compiler. The first being broken semaphore locking.
8397 *) Updated mime.types to reflect current Internet media types
8398 and include a URL to the registry.

8402 an infinite loop of recursive SSI includes. [Marc Slemko] PR#3323
8404 *) Add APACI --suexec-docroot and --suexec-logfile options which can be
8405 used to set the document root directory (DOC_ROOT) and the suexec
8406 logfile (LOG_EXEC), respectively. Additionally the --layout option
8407 was changed to show more information about the suEXEC setup.

8410 *) Added the last two WebDAV status codes of 424 (Failed Dependency)
8411 and 507 (Insufficient Storage) for use by third-party modules.
8414 *) Enabled all of the WebDAV method names for use by third-party
8415 modules, Limit, and Script directives. That includes PATCH,
8416 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
8417 Improved mod_actions.c so that it can use any of the methods

8442 the interpreter and the Win32 error code returned. [Marc Slemko]
8444 *) Disable sending of error-notes on a 500 (Internal Server Error) response
8445 since it often includes file path info. Enable sending of error-notes
8446 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
8448 *) http_config.c would respond with 501 (Method Not Implemented) if a
8449 content type handler was specified but could not be found, which
8450 should have been a 500 response. Likewise, mod_proxy.c would responsd
8451 with a 501 if the URI scheme is unrecognized instead of the correct
8452 response of 403 (Forbidden). [Roy Fielding]
8454 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
8455 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
8457 *) Fix in mod_autoindex: for files where the last modified time stamp was
8458 unavailable, an empty string was printed which was 2 bytes short.
8459 The size and description columns were therefore not aligned correctly.
8460 [Martin Kraemer] (no PR#)

8463 release A17, the child fork() must be replaced by a _rfork().

8466 *) Add the actual server_rec structure of the specific Vhost to the
8467 scoreboard file and avoid a string copy (as well as allow some
8468 further future enhancements). [Harrie Hazewinkel
8469 <harrie.hazewinkel jrc.it>]
8471 *) Add APACI --permute-module=foo:bar option which can be used to
8472 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
8473 in the Configuration[.apaci] file. Two special and important variants are
8474 supported for the option argument: first BEGIN:foo which permutes module
8475 mod_foo with the begin of the module list, i.e. it `moves' the module to
8476 the begin of the list (gives it lowest priority). And second foo:END
8477 which permutes mod_foo with the end of the module list, i.e. it `moves'
8478 the module to the end of the list (gives it highest priority).

8520 *) Add a "default-handler" handler that calls the default_hander()
8521 function which is normally called for static content. This allows
8522 you to override a specific handler. [Marc Slemko]

8525 hard-coded syntax check with a call to a routine we already created to
8526 do this. [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2976, 3074
8528 *) Log an error if we encounter a malformed "require" directive
8529 in mod_auth if we know that we know that no other module can
8530 deal with it. [Marc Slemko]
8532 *) Remove ap_private_extern method of hiding conflicting symbols

8534 and the versions for which it is correct are unknown.

8547 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
8549 Changes with Apache 1.3.3
8551 *) Added a complete implementation of the Expect header field as
8552 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
8553 response when we already know the final status, which is mighty
8554 useful for PUT responses that result in 302 or 401. [Roy Fielding]
8556 *) Remove extra trailing whitespace from the getline results as part
8557 of the protocol processing, which is extra nice because it works
8558 between continuation lines, is almost no cost in the normal case
8559 of no extra whitespace, and saves memory. [Roy Fielding]
8561 *) Added new HTTP status codes and default response bodies from the
8562 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
8563 HTTP Extension Framework (510) specifications. Did not add the
8564 WebDAV 424 and 425 codes because they are bogus. We don't use any
8565 of these codes yet, but they are now available to 3rd-party modules.
8568 *) Fix a possible race condition between timed-out requests and the
8569 ap_bhalfduplex select that might result in an infinite loop on
8570 platforms that do not validate the descriptor. [Roy Fielding]

8681 You now must define a BS2000Account name for the server User.
8682 This has fewer security implications than the old approach.
8685 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
8686 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
8687 platform to make the braindead HPUX linker happy. Notice, for the module
8688 DSOs we don't have to use this, because these are loaded manually (and
8689 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

8700 *) Make PrintPath work generically instead of having one version
8701 strictly for OS/2. [Jim Jagielski, Brian Havard]
8703 *) Fix the recently introduced C header file checking: We now use the C
8704 pre-processor pass only (and no longer the complete compiler pass) to
8705 determine whether a C header file exists or not. Because only this way
8706 we're safe against inter-header dependencies (which caused horrible
8707 portability problems). The only drawback is that we now have a CPP
8708 configuration variable which has to be determined first (we do a similar
8709 approach as GNU Autoconf does here). When all fails the user still has
8710 the possibility to override it manually via APACI or src/Configuration.
8711 As a fallback for the header check itself we can directly check the
8712 existance of the file under /usr/include, too.

8745 because our GuessOS is still unaware of Digital UNIX versions and the
8746 -msym is just to optimize the DSO statup time a little bit it's safe and
8747 best when we leave it out now. [Ralf S. Engelschall] PR#2969

8752 (instead it directly passes through the message to be formatted to the
8753 real internal formatting function). [Ralf S. Engelschall] PR#2941
8755 *) Allow "Include" directives anywhere in the server config
8756 files (but not .htaccess files). [Ken Coar] PR#2727
8758 *) The proxy was refusing to serve CONNECT requests except to
8759 port 443 (https://) and 563 (snews://). The new AllowCONNECT
8760 directive allows the configuration of the ports to which a
8761 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
8763 *) mod_expires will now act on content that is not sent from a file
8764 on disk. Previously it would never add an Expires: header to
8765 any response that did not come from a file on disk; the only
8766 case where it still doesn't (and can't) add one for that type of
8767 content is if you are using a modification date based setting.
8768 [Marc Slemko, Paul Phillips <paulp go2net.com>]
8770 *) Problems encountered during .htaccess parsing or CGI execution
8771 that lead to a "500 Server Error" condition now provide explanatory
8772 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
8775 *) Add NameWidth keyword to IndexOptions directive so that the
8776 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
8779 *) Recognize lowercase _and_ uppercase `uname' results under
8780 SCO OpenServer. [David Coelho <drc ppt.com>]
8782 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
8783 a common problem of (mis-administrated?) IIS servers, make the apache
8784 proxy immune to these errors (and ignore the duplicates, but log
8785 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
8787 *) The <IfModule and <IfDefine block starting directives now only
8788 allow exactly one argument. Previously, the optional negation
8789 character '!' could be separated by whitespace without a syntax
8790 error being reported, albeit defeating the IfModule functionality
8791 (enclosed directives would ALWAYS be executed). By using the
8792 stricter syntax, these hard-to-track errors can be avoided.
8795 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
8796 cause the standalone FancyIndexing directive to logically OR
8797 into any existing IndexOptions settings rather than wiping
8798 them out. [Ken Coar]
8800 *) Changes in ftp proxy: make URL parsing simpler by using the
8802 + Add display of the "current directory" in cases where it's
8803 different from the supplied path (e.g., ftp://user@host/ lives
8804 in /home/user, not in /, therefore clicking on "../" in the
8805 starting directory might send us to /home/).
8806 + When ftp login fails, (esp. when a user name was part of the
8807 URL already), we now return [401 Unauthorized ] to allow the
8808 browser to pop up an authorization dialog. This makes passwords
8809 slightly less visible (they don't appear in the regular log files)
8810 and implements a functionality that other www proxy servers
8814 *) Triggered by the recent "Via:" header changes, the proxy module would
8815 dump core for replies with invalid headers (e.g., duplicate
8816 "HTTP/1.0 200 OK" lines). These errors are now logged and the
8817 core dump is avoided. Also, broken replies are not cached.

8834 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
8835 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
8836 without complains after we recently added the POST feature.
8837 [Ralf S. Engelschall]
8839 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
8840 modules as API functions and we forgot them at the big symbol renaming.

8852 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
8853 5 to 10 because there are some users out there who always have 5 to 8
8854 variables in one RewriteRule and had to patch mod_rewrite.h for every
8855 release. So 15 should be now more than enough, even for them. (I never
8856 needed more than 4 in my RewriteRules ;-)
8857 [Ralf S. Engelschall]
8859 *) Make the proxy generate and understand Via: headers
8862 *) Change the proxy to use tables instead of array_headers for
8863 the header lines. [Martin Kraemer]
8865 *) Make sure the config.status file is not overridden when just
8866 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
8868 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
8869 provide a way to trace API changes that add functionality but do
8870 not create a compatibility issue for precompiled modules, etc.

8878 compile time, for least astonishment of the user.
8881 *) When READing a request in ExtendedStatus mode, the "old"
8882 vhost, request and client information is not displayed.
8885 *) STATUS is no longer available. Full status information now
8886 run-time configurable using the ExtendedStatus directive.
8889 *) SECURITY [CVE-1999-1199] (cve.mitre.org):
8890 Eliminate O(n^2) space DoS attacks (and other O(n^2)
8891 cpu time attacks) in header parsing. Add ap_overlap_tables(),
8892 a function which can be used to perform bulk update operations
8893 on tables in a more efficient manner.
8896 *) SECURITY: Added compile-time and configurable limits for
8897 various aspects of reading a client request to avoid some simple
8898 denial of service attacks, including limits on maximum request-line
8899 size (LimitRequestLine), number of header fields (LimitRequestFields),
8900 and size of any one header field (LimitRequestFieldsize). Also added
8901 a configurable directive LimitRequestBody for limiting the size of the
8902 request message body. [Roy Fielding]

8905 STATUS not defined. [Jim Jagielski]

8918 ap_scan_script_header_err_core() [Doug MacEachern]
8920 *) The 'status' module will now show the process pid's and their
8921 state even without full STATUS accounting. [Jim Jagielski]
8923 *) Restore the client IP address to the error log messages, this
8924 was lost during the transition from 1.2 to 1.3. Add a new
8925 function ap_log_rerror() which takes a request_rec * and
8926 formats it appropriately. [Dean Gaudet] PR#2661
8928 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
8929 whitespace in input lines -- including within quoted strings.
8931 but leading and trailing whitespace should continue to be
8932 stripped [Martin Kraemer]
8934 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
8935 the ugly use of an env. variable and use command-line args for
8936 alternate $PATH. Make more like advanced 'type's as well.
8939 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
8940 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis

8943 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
8945 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
8946 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
8947 directory was renamed to src/os/os2/ for consistency.
8948 [Brian Havard, Ralf S. Engelschall]
8950 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
8951 files (here modules) against other DSO files (here shared libraries).
8952 This is done by determining a subset of LIBS which can be safely used for
8953 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
8954 disabled for all platforms to avoid problems with this (experimental)
8955 rule. But we provide it now for those people how ran into problems and
8956 want to came out by forcing linking against DSOs.

8971 handling loop so that the connection can be properly closed with
8972 lingering_close, thus avoiding a potential TCP reset that would
8973 cause the client to miss the HTTP error response. [Roy Fielding]
8975 *) One more portability fix for APACI shadow tree support: Swap order of awk
8976 and sed in top-level configure script to avoid sed fails on some
8977 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
8978 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729

8985 *) Fix Win32 part of ap_spawn_child() by providing a reasonable child_info
8986 structure instead of just NULL. This fixes at least the RewriteMap
8987 programs under Win32. [Marco De Michele <mdemichele tin.it>] PR#2483

9002 for users which extracted the distribution under 'umask 077'), so replace
9003 it by an explicit cp+chmod approach.

9035 the read_request error conditions of URI-too-long (414) and
9036 malformed header fields (400). [Roy Fielding] PR#2646
9038 *) Add support for the Max-Forwards: header line required by RFC2068 for
9039 the TRACE method. This allows apache to TRACE along a chain of proxies
9040 up to a predetermined depth. [Martin Kraemer]
9042 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled
9043 (compilers complained) and the .so.V.R.P filename extension was adjusted
9044 to correctly reflect the 1.3.2 version.

9074 the scheme://sitepart string only, or to omit the query string.
9077 *) WIN32: Canonicalize ServerRoot before checking to see if it
9078 is a valid directory. The failure to do this caused certain
9079 ServerRoot settings (eg. "ServerRoot /apache") to be improperly
9080 rejected. [Marc Slemko]
9082 *) Global renaming of C header files to both get rid of conflicts with third
9083 party packages and to again reach consistency:
9084 1. conf.h -> ap_config.h
9085 2. conf_auto.h -> ap_config_auto.h \ these are now merged
9086 3. ap_config.h -> ap_config_auto.h / in the config process
9087 4. compat.h -> ap_compat.h
9088 5. apctype.h -> ap_ctype.h
9089 Backward compatibility files for conf.h and compat.h were created.
9091 *) mod_mmap_static will no longer take action on requests unless at
9092 least one "mmapfile" directive is present in the configuration.
9093 This experimental module has to do some black magic to operate
9094 inside the current API and thus creates side-effects for other
9095 modules under some circumstances.
9096 [Ralf S. Engelschall]
9098 *) Add conservative ticks around more egrep arguments in top-level configure
9099 to avoid problems under brain-dead platforms like Digital UNIX (OSF1).
9100 [Ralf S. Engelschall] PR#2596
9102 *) mod_rewrite created RewriteLock files under the UID of the parent
9103 process, thus the child processes had no write access to the files.
9104 Now a chown() is done on the file to the uid of the children,
9105 if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341
9107 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
9108 TestCompile) instead of defining them manually in conf.h based on less
9109 accurate platform definitions. This way we no longer have to fiddle with
9110 OS-type and/or OS-version identifiers to discover whether a system header
9111 file exists or not. Instead we now directly check for the existence of
9112 those esoteric ones.

9117 field with "^$". [Ken Coar]
9119 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
9120 modules to load their own modules dynamically. This improves mod_perl
9121 and mod_php3 when these modules are loaded dynamically into Apache.
9124 *) Cache a proxied request in the event that the client cancels the
9125 transfer, provided that the configured percentage of the file has
9126 already been transfered. It works for HTTP transfers only. The
9127 new configuration directive is called CacheForceCompletion.

9152 *) The APACI libexecdir was not extended with an "apache/" subdir
9153 if the installation prefix didn't already contain "apache", but
9154 it should be because the DSO files are Apache-specific. Now
9155 libexecdir is treated the same way sysconfdir, datadir, localstatedir
9156 and includedir are already treated.

9209 directory, bail out of the request with an error message. [W G Stoddard]
9211 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
9212 these are treated by Win32 as if they are ".." but are not detected by
9213 other machinery within Apache. This is something of a kludge but
9214 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
9216 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
9217 pools and thus pollutes libap (until the pool stuff is moved there).

9231 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
9232 remove some of the classical hurdles for new users when setting up
9233 Apache. This is done per default because it is useful for the average
9234 user. Package authors can use the --without-confadjust option to disable
9235 these configuration adjustments.
9236 [Ralf S. Engelschall]
9238 *) Added an EXTRA_DEPS configuration parameter which can be used

9244 as <IfModule>..</IfModule> sections) which can be used to skip or process
9245 contained commands dependend of ``-D PARAMETER'' options on the command
9246 line. This can be used to achieve logical conditions like <IfDefine
9247 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
9248 and thus especially can be used for conditionally loading DSO-based
9249 modules via LoadModule, etc. [Ralf S. Engelschall]

9260 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
9261 in top-level configure script to avoid sed fails on some platforms (for
9262 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
9263 output of Awk. [Bill Houle <bhoule sandiegoca.ncr.com>] PR#2435
9265 *) Improve performance of directory listings (mod_autoindex) by comparing
9266 integer keys (last-modified and size) as integers rather than converting
9267 them to strings first. Also use a set of explicit byte tests rather
9268 than strcmp() to check for parent directory-ness of an entry. Oh, and
9269 make sure the parent directory (if displayed) is *always* listed first
9270 regardless of the sort key. Overall performance winnage should be good
9271 in CPU time, instruction cache, and memory usage, particularly for large
9272 directories. [Ken Coar]
9274 *) Add a tiny but useful goody to APACI's configure script: The generation
9275 of a config.status script (as GNU Autoconf does) which remembers the used
9276 configure command and hence can be used to restore the configuration by
9277 just re-running this script or for remembering the configuration between
9279 [Ralf S. Engelschall]
9281 *) Add httpd -t (test) option for running configuration syntax tests only.
9282 If something is broken it complains and exits with a return code
9283 non-equal to 0. This can be used manually by the user to check the Apache
9284 configuration after editing and is also automatically used by apachectl
9285 on (graceful) restart command to make sure Apache doesn't die on restarts
9286 because of a configuration which is now broken since the last (re)start.
9287 This way `apachectl restart' can be used inside cronjobs without having
9288 to expect Apache to be falling down. Additionally the httpd -t can be run
9289 via `apachectl configtest'.

9348 *) Change "Options None" to "Options FollowSymLinks" in the
9349 <Directory /> section of the default access.conf-dist

9360 *) Workaround for configure script and old `test' commands which do not
9361 support the -x flag (for instance under platforms like Ultrix). This is

9363 Awk like PrintPath but _via different names_.

9388 Changes with Apache 1.3.0
9390 *) Using a type map file as a custom error document was not possible.

9393 *) Avoid problems with braindead Awks by additionally searching for gawk
9394 and nawk in APACI's configure script.

9397 *) Rename md5.h to ap_md5.h to avoid conflicts with native MD5 on
9398 some systems. [Randy Terbush]
9400 *) Change usage of perror()+fprintf(stderr,...) in mod_rewrite to
9401 more proper ap_log_error() variants.
9402 [Ralf S. Engelschall]
9404 *) Make sure the argument for the --add-module option to APACI's configure
9405 script is of type [path/to/]mod_xxx.c because all calculations inside
9406 configure and src/Configure depend on this.
9407 [Ralf S. Engelschall] PR#2307
9409 *) Changes usage of perror/fprintf to stderr to more proper ap_log_error
9410 in mod_mime, mod_log_referer, mod_log_agent, and mod_log_config.
9413 *) Various OS/2 cleanups ["Brian Havard" <brianh kheldar.apana.org.au>]

9423 *) Propagate environment to CGI scripts correctly in Win32.
9424 [W G Stoddard <wgstodda us.ibm.com>] PR#2294
9426 *) Some symbol renaming:
9427 ap_spawn_child_err became ap_spawn_child
9428 ap_spawn_child_err_buff became ap_bspawn_child
9429 spawn_child was obsoleted and moved to compat.h
9432 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
9433 programs: ap_spawn_child_err() is used and the Win32 case now uses
9434 CreateProcess() instead of a low-level execl() (which caused problems in
9435 the past under Win32).
9436 [Ralf S. Engelschall]
9438 *) A few cosmetics and trivial enhancements to APXS to make the
9439 generated Makefile more user friendly. [Ralf S. Engelschall]
9441 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
9442 was updated to use the normal apache error processing, thereby allowing
9443 proxy errors to be treated by ErrorDocument's as well. For this
9444 purpose, a new module-to-core communication variable "error-notes"
9445 was introduced; the proxy (and possibly other modules) communicates
9446 its error text using this variable. Its content is copied to a new
9447 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
9448 The old proxy special error routine ap_proxy_log_uerror()
9449 was replaced by regular ap_log_error() calls, many messages were made
9451 [Martin Kraemer] PR#494, 1259
9453 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
9456 *) Transform the configure message "You need root privileges for suEXEC"
9457 from a fatal error into a (more friendly) warning because the building
9458 ("make") of Apache we can allow, of course. Root privileges are needed
9459 only for the installation step ("make install"). So make sure the
9460 user is aware of this fact but let him proceed as long as he can.
9461 [Ralf S. Engelschall] PR#2288
9463 *) Renamed three more functions to common ap_ prefix which we missed at the
9464 Big Symbol Renaming because they're #defines and not real C functions:
9465 is_default_port(), default_port(), http_method().
9466 [Ralf S. Engelschall]
9468 *) A zero-length name after a $ in an SSI document should cause
9469 just the $ to be in the expansion. This was broken during the

9476 used under AIX) because of recent changes to function names.
9477 [Ralf S. Engelschall]
9479 Changes with Apache 1.3b7
9481 *) Make sure a MIME-type can be forced via a RewriteRule even when no
9482 substitution takes place, for instance via the following rule:
9483 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
9484 requested by users in the past to force a single script without a .cgi
9485 extension and outside any cgi-bin dirs to be executed as a CGI program.

9488 *) A fix for protocol issues surrounding 400, 408, and
9489 414 responses. [Ed Korthof]

9493 *) Fix discrepancy in proxy_ftp.c which was causing failures when
9494 trying to connect to certain ftpd's, such as anonftpd.
9495 [Rick Ohnemus <rick ecompcon.com>]
9497 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
9498 logfile instead of fiddling around itself with child spawning stuff.
9499 [Ralf S. Engelschall]
9501 *) Made RefererIgnore case-insensitive.
9503 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.

9507 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
9510 *) Improve RFC1413 support. [Bob Beck <beck bofh.ucs.ualberta.ca>]
9512 *) Fix support script `dbmmanage': It was unable to handle some sort
9513 of passwords, especially passwords with "0" chars.
9514 [Ralf S. Engelschall] PR#2242
9516 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
9517 [Ben Laurie] PR#2238
9519 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
9520 library), so CGI handling has been changed to use Win32 native handles
9521 instead of C file descriptors.
9522 [Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
9524 *) The proxy cache would store an incorrect content-length in the cached
9525 file copy after a cache update. That resulted in repeated fetching
9526 of the original copy instead of using the cached copy.
9527 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
9529 *) The Makefiles assumed that DSO files are build via $(LD). This
9530 is broken for two reasons: First we never defined at least LD=ld
9531 somewhere to make sure this works (it was silently assumed that most Make
9532 provide a built-in LD definition - ARGL!) and second using the generic LD
9533 variable is not the truth. Instead a special variable named LD_SHLIB is
9534 reasonable because although "ld" is usually the default, the command for
9535 building DSO files can be "libtool" or even "cc" on some systems.
9536 [Ralf S. Engelschall]
9538 *) Replace the AddVersionPlatform directive with ServerTokens which
9539 provides for more control over the format of the Server:
9540 header line. SERVER_SUBVERSION is no longer supported;
9541 all module should use the ap_add_version_component()
9542 API function instead. [Jim Jagielski]
9544 *) Support for the NCR MP/RAS 3.0
9545 [John Withers <withers semi.kcsc.mwr.irs.gov>]
9547 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
9548 not retrieved in src/Configure and thus was not useable.
9549 [Ralf S. Engelschall]
9551 *) Various Makefile consistency cleanups:
9552 - make OSDIR also automatically be relative to src/ like INCDIR
9553 - SUBDIRS is now generated in src/Makefile only and not in
9554 Makefile.config because it is a local define for this location.
9555 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
9556 any Makefile but make sure that at least the "-K inline" is kept in
9558 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
9559 - updated the dependencies theirself
9560 - removed not existing SHLIB variable from "clean" targets
9561 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
9562 already exists and OBJS_PIC are also just plain objects and have not
9563 directly to do with "shared" things. The only difference is that they
9564 contain PIC. So OBJS_PIC is the more canonical name.
9565 - Updated the Makefile-dependency lines for OBJS_PIC
9566 - Removed the Makefile-dependency line in Configure to avoid double
9568 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
9569 of xxx.lo as GNU libtool does with its PIC objects
9570 - reduce local complexity in modules Makefile.tmpl by moving the last
9571 existing target "depend" to the generation section in Configure, too.
9572 - removed the historical $(SPACER) which was used in the past together
9573 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
9574 is no longer needed.
9575 - force the build and run of the gen_xxx programs under main/ as the
9576 first step before building the objects because it looks cleaner
9577 [Ralf S. Engelschall]
9579 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
9582 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
9585 *) WIN32: Don't force ISAPI headers to finish with \n.
9586 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
9588 *) When opening "configuration" files (like httpd.conf, htaccess
9589 and htpasswd), Apache will not allow them to be non-/dev/null
9590 device files. This closes a DoS hole. At the same time,
9591 we use ap_pfopen to open these files to handle timeouts.
9592 [Jim Jagielski, Martin Kraemer]
9594 *) Apache will now log the reason its httpd children exit if they exit
9595 due to an unexpected signal. (It requires a new porting define,
9596 SYS_SIGLIST, which if defined should point to a list of text
9597 descriptions of the signals available. See PORTING.) [Dean Gaudet]
9599 *) WIN32: chdir() doesn't make sense in a multithreaded environment
9600 like WIN32. Before, Win32 CGI's could have had sporadic failures
9601 if a chdir call from one thread was made between another chdir call
9602 and a spawn in another thread. So, for now don't chdir for CGI scripts
9603 in WIN32. The current CGI "spec" is unclear as to whether it's
9604 necessary. Long-term fix is to either serialize the chdir/spawn combo
9605 or use WIN32 native calls to spawn a process. This temp fix was
9606 necessary to remove this as a showstopper for 1.3's release.
9609 *) Cleanup the suEXEC support in APACI and make it more safe:
9610 1. Add big fat hint in INSTALL about risks and to read the
9611 htdocs/manual/suexec.html document before using the suexec-related
9613 2. Make sure the user has at least provided one --suexec-xxxx option
9614 (specifies suEXEC parameters) in addition to --enable-suexec option.
9615 If only --enable-suexec is given APACI stops with a hint to INSTALL
9616 and htdocs/manual/suexec.html documents.
9617 3. Provide two additional --suexec-xxxx options to make the suEXEC
9618 configuration complete (especially for package maintainers who else
9619 had to patch the source tree) by providing ways to configure minimal
9620 UID/GID and safe PATH, too.
9621 [Ralf S. Engelschall]
9623 *) Cleanup of the `configure --shadow' process:
9624 - make sure the configure script creates its temporary files in the
9625 shadow tree to avoid conflicts with parallel configure runs
9626 - removed unnecessary option "-r" from "rm" call for Makefiles
9627 - make sure the configure scripts creates the shadow-wrapper Makefile
9628 only when no shadow trees already exists
9629 - make sure "make distclean" removes the shadow-wrapper Makefile but only
9630 when no more shadow trees exists
9631 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
9632 as fast (in the past it needed 70sec, now it runs just 38sec)
9633 - make sure CVS does not complain about the created files
9634 Makefille.<gnutriple> and directories src.<gnutriple>
9635 [Ralf S. Engelschall]
9637 *) Added the ap_add_version_component() API routine and the
9638 AddVersionPlatform core directive. The first allows modules to
9639 declare themselves in the Server response header field value,
9640 augmenting the SERVER_SUBVERSION define in the Configuration file
9641 with run-time settings (more useful in a loadable-module environment).
9642 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
9643 into the server version string. [Ken Coar] PR#2056
9645 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
9648 *) Emit the "Accept-Range" header for the default handler.
9649 [Brian Behlendorf] PR#1464
9651 *) Add a note to httpd.conf-dist that apache will on some systems fail
9652 to start when the Group # is set to a negative or large positive value.
9655 *) Make sure the module execution order is correct even when some modules
9656 are loaded under runtime (`LoadModule') via the DSO mechanism:
9657 1. The list of loaded modules is now a dynamically allocated one
9658 and not the original statically list from modules.c
9659 2. The loaded modules are now correctly setup by LoadModule for
9660 later use by the AddModule command.
9661 3. When the DSO mechanism for modules is used APACI's `install'
9662 target now enables all created `LoadModule' lines per default because
9663 this is both already expected by the user _and_ needed to avoid
9664 confusion with the next point and reduces the Makefile.tmpl complexity
9665 4. When the DSO mechanism for modules is used, APACI's `install'
9666 target now additionally makes sure the module list is reconstructed
9667 via a complete `ClearModuleList+AddModule...' entry.
9668 5. The support tool `apxs' now also makes sure an AddModule command
9669 is added in addition to the LoadModule command.
9670 6. The modules.c generation was extended to now contain two
9671 comments to make sure no one is confused by the confusing terminology
9672 of loading/linking (we use load=link+load & link=activate instead of
9673 the obvious load=activate & link=link :-( )
9674 This way now there is no longer a difference under execution time between
9675 statically and dynamically linked modules.
9676 [Ralf S. Engelschall]
9678 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
9679 Big Symbol Renaming. [Ralf S. Engelschall]
9681 *) Add a comment to mod_example.c showing the format of a FLAG command
9684 *) Standardized the time format in mod_status to match that of other
9685 places in the code (e.g. DATE_GMT). PR#1551
9687 *) Fix handling of %Z in timefmt strings for those platforms with no time
9688 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
9691 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
9692 feature compatible with 'UseCanonicalName off' by changing
9693 r->server->server_hostname to ap_get_server_name(). And I changed some
9694 functions which use r->server->port to use ap_get_server_port() instead,
9695 because if there's no Port directive in the config r->server->port is 0.
9698 *) get/set_module_config are trivial enough to be better off inline. Worth
9699 1.5% performance boost. [Dean Gaudet]
9701 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
9702 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
9705 *) [BS2000 security] BS2000 needs an extra authentication to initialize
9706 the task environment to the unprivileged User id. Otherwise CGI scripts
9707 would have a way to gain super user access. [Martin Kraemer]
9709 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
9710 absolute path, only log base name of logging source as is done
9711 in unix. [Martin Kraemer]
9713 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
9714 the encoding type from the Accept-Encoding header (if it's there)
9715 and use it in the response, as that's probably what it'll be expecting.
9716 [<Ronald.Tschalaer psi.ch>]
9718 *) Fix to mod_alias: translate_alias_redir is dealing with
9719 a URI, not a filename, so the check for drive letters for win32
9720 and emx is not necessary. [Dean Gaudet]
9722 *) WIN32: Allow .cmd as an executable extension.
9723 [Kari Likovuori <Kari.Likovuori mol.fi>] PR#2146
9725 *) Make Apache header files, and some variables, C++ friendly.
9726 [Michael Anderson's <mka redes.int.com.mx>]
9728 *) Child processes can now "signal" (by exiting with a status
9729 of APEXIT_CHILDFATAL) the parent process to abort and
9730 shutdown the server if the error in the child process was
9731 fatal enough. [Jim Jagielski]
9733 *) mod_autoindex's find_itme() was sensitive to MIME type case.
9734 [Jim Jagielski] PR#2112
9736 *) Make sure the referer_log and agent_log entries in the default httpd.conf
9737 file are also adjusted for the actual relative installation paths.
9738 [Ralf S. Engelschall] PR#2175
9740 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
9742 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
9745 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
9746 Additionally the checks for finding the vendor DSO library were moved
9747 from mod_so.c to Configure because first it needs $PLAT etc. and second
9748 mod_so already uses an abstraction layer and does not fiddle with the
9749 vendor functions itself.
9750 [Jens-Uwe Mager, Ralf S. Engelschall]
9752 *) PORT: Some optimization defines for NetBSD
9753 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
9755 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
9756 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
9758 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
9759 AIX variants should work fine, too. Even AIX 3.x should work). This is
9760 accomplished by using the free DSO emulation code from Jens-Uwe Mager
9761 which we put into a os/unix/os-dso-aix.c file.
9762 [Ralf S. Engelschall]
9764 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
9765 that we should use NET_SIZE_T == int but the include files force size_t.
9766 [Ralf S. Engelschall]
9768 *) Fix two bugs in select() handling in http_main.c.
9771 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
9772 is unset (as it is in situations like timeouts) where it is unclear
9773 whether errno is set or not. [Martin Kraemer]
9775 *) Just having APACI's localstatedir is too general and not enough for most
9776 of the systems. 1.3b6 again required manual APACI patches by package
9777 maintainers from Red Hat and FreeBSD because for their filesystem layout a
9778 little bit more flexibility in configuring the paths is needed. Hence we
9779 provide three additional configure options (--runtimedir, --logfiledir,
9780 --proxycachedir) which now can be used for more granular adjustments if
9781 --localstatedir is not enough to fit the particular needs. As a nice
9782 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
9783 [Ralf S. Engelschall]
9785 *) Make the install root for "make install" in APACI's Makefile overrideable
9786 by package authors. This way we are even more friendly to package
9787 maintainers (especially Debian and Red Hat) who build for the real prefix
9788 via "configure --prefix=/<real>" but use a different local prefix via
9789 "make root=/tmp/apache install" for rolling the package without bristling
9790 the target location on their system.
9791 [Ralf S. Engelschall]
9793 *) Workaround sed limitations in APACI's configure script by now
9794 substituting in chunks of 50 commands (because for instance HPUX's vendor
9795 sed has a limit of max. 98 commands)
9796 [Ralf S. Engelschall] PR#2136
9798 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
9799 [Ralf S. Engelschall] PR#2140
9801 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
9802 RENAMING process because they are defined as pre-processor macros instead
9803 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
9804 [Ralf S. Engelschall]
9806 *) Workaround braindead AWK's when generating ap_config.h: The split() and
9807 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
9808 [Ralf S. Engelschall] PR#2139
9810 *) Various bugfixes and cleanups for the APACI configure script:
9811 o fix IFS handling for _nested_ situation
9812 o fix Perl interpreter search: take first one found instead of last one
9813 o fix DSO consistency check
9814 o print error messages to stderr instead of stdout
9815 o add install-quiet for --shadow situation to Makefile stub
9816 o reduce complexity by avoiding sed-hacks for rule and module list loops
9817 [Ralf S. Engelschall]
9819 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
9821 *) Make sure the input field separator (IFS) shell variable is explicitly
9822 initialized correctly before _every_ `for' loop and also restored after
9823 the loops. [Ralf S. Engelschall]
9825 *) Make sure that "make install" doesn't overwrite the `mime.types' and
9826 `magic' files from an existing Apache installation. Because people often

9830 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
9831 [Peter Galbavy, Ralf S. Engelschall] PR#2109
9833 *) Fix the path to the ScoreBoardFile in the install-config target, too.
9834 [Ralf S. Engelschall] PR#2105
9836 *) Let "configure" clear out the users parameters (provided as shell
9837 variables) to avoid side-effects in "src/Configure" when the user
9838 exported them (which is not needed, but some users do it).
9839 [Ralf S. Engelschall] PR#2101
9841 *) Provide backward compatibility from some old src/Configuration.tmpl
9842 parameter names to the canonical Autoconf-style shell variable names. For
9843 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
9844 but a hint message is displayed. [Ralf S. Engelschall]
9846 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
9847 CGI scripts from an existing Apache installation.
9848 [Ralf S. Engelschall, Jim Jagielski] PR#2084
9850 *) Make `configure --compat' more "compatible" by first
9851 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
9852 second by making sure the "avoid-bristling-suffix" /apache is not
9853 appended to sysconfdir, datadir, localstatedir and includedir when
9854 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
9856 *) NeXT required strdup() in support/logresolve.c

9862 *) Fix the path to the MimeMagicFile in the install-config target, too.
9863 [Ralf S. Engelschall] PR#2089
9865 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
9867 *) If you start apache with the -S command line option it will dump
9868 out the parsed vhost settings. This is useful for folks trying
9869 to figure out what is wrong with their vhost configuration.
9870 (Other dumps may be added in the future.) [Dean Gaudet]
9872 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
9873 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
9876 *) Because /usr/local/apache is the default prefix the ``configure
9877 --compat'' option no longer has to set prefix, again. This way the
9878 --compat option honors a leading --prefix option. [Lars Eilebrecht]
9880 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
9881 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
9882 to avoid "discard const" warnings. [Ralf S. Engelschall]
9884 *) If a specific handler is set for a file yet the request still
9885 ends up being handled by the default handler, log an error
9886 message before handling it. This catches things such as trying
9887 to use SSIs without mod_include enabled. [Marc Slemko]
9889 *) Fix error logging for the startup case where ap_log_error() still uses
9890 stderr as the target. Now the default log level is honored here, too.
9891 [Ralf S. Engelschall]
9893 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
9894 long" errors when generating the MODULES entry for src/Makefile
9895 [Ben Hyde, Ralf S. Engelschall]
9897 *) Make sure src/Configure doesn't complain about the old directory
9898 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
9900 Changes with Apache 1.3b6
9902 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
9904 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
9905 interface via the similar but proprietary HP/UX shl_xxx-style system
9906 calls. [Ralf S. Engelschall]
9908 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
9909 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
9910 Make. [Ralf S. Engelschall]
9912 *) ++++ THE BIG SYMBOL RENAMING ++++
9913 To avoid symbol clashes with third-party code compiled into the server,
9914 we globally applied the prefix "ap_" to the following classes of
9916 - Apache provided general functions (e.g., ap_cpystrn)
9917 - Public API functions (e.g., palloc, bgets)
9918 - Private functions which we can't make static (because of
9919 cross-object usage) but should be (e.g., new_connection)
9920 For backward source compatibility a new header file named compat.h was
9921 created which provides defines for the old symbol names and can be used
9922 by third-party module authors.
9925 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
9926 problem under SVR4 is that there is no command flag to force the linker
9927 to export the global symbols of the httpd executable therewith they are
9928 available to the DSO's. Instead of problematic hacks like creating a
9929 dummy.so file (containing dummy references to all global symbols) the
9930 httpd binary is linked against, we use a clean trick stolen from Perl 5:
9931 Placing the Apache core code itself into a DSO library named libhttpd.so.
9932 This way the global symbols _HAVE_ to be exported and thus are available
9933 to any manually loaded DSO's under runtime. To reduce the impact to the
9934 user to null we go even further and create a stub httpd executable which
9935 automatically keeps track of the DSO library loading itself and thus
9936 hides the complete mechanism from the user. Although the generation of
9937 this DSO library is automatically triggered for platforms which
9938 essentially need it (mostly all SVR4-derivates) it can be also enabled
9939 manually via the Rule SHARED_CORE. This can be interesting in the future
9940 where we perhaps exploit this libhttpd.so mechanism for providing nifty
9941 features like graceful upgrades, or whatever.
9942 [Ralf S. Engelschall, Martin Kraemer]
9944 *) Build the libraries before building the rest of the tools. [Ben Hyde]
9946 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
9947 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
9948 conventions while "clean" removes only stuff created by "all" targets,
9949 "distclean" additionally removes the stuff from the configuration
9950 process. This way "make distclean" (hence the name) provides a fresh
9951 source tree as it was for distribution.
9952 [Ralf S. Engelschall]
9954 *) Allow top-level (APACI) Makefile to break on build errors
9955 the same way the src/ subtree Makefiles breaks on them by replacing the
9956 initial APACI sed-subdir-display-kludge with a more clean
9957 variable-passing-solution: variable SDP can optionally hold the subdir
9958 prefix which is consistently used for displaying the subdir movement.
9959 This way even the top-level Makefile can stop correctly on errors as the
9960 user expects. [Ralf S. Engelschall]
9962 *) Fixed ordering of argument checks for RewriteBase directive.
9963 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
9965 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
9966 indicating that a module is being compiled for dynamic loading. Also
9967 remove #define IS_MODULE from modules and add SHARED_MODULE define
9968 to the mak/dsp files. [Alexei Kosut]
9970 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
9971 since we are now logging APLOG_WARNING by default. [Roy Fielding]
9973 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
9975 *) Add documentation file and src/Configuration.tmpl entry for the
9976 experimental mod_mmap_static module. Because although it is and marked as
9977 an experimental one it is distributed and thus should be documented and
9978 prepared for configuration the same way as all others modules.
9979 [Ralf S. Engelschall]
9981 *) Add query (-q) option to apxs support tool to be able to manually query
9982 specific settings from apxs. This is needed for instance when you
9983 manually want to access Apache's header files and you need to assemble
9984 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
9985 [Ralf S. Engelschall]
9987 *) Now src/Configure uses a fallback strategy for the shared object support
9988 on platforms where no explicit information is available: If a Perl
9989 installation exists we ask it about its shared object support and if it's
9990 the dlopen-style one we shamelessly guess the compiler and linker flags
9991 for creating shared objects from Perls knowledge. Of course, the user is
9992 warning about what we are doing and informed that he should send us
9993 the guessed flags when they work. [Ralf S. Engelschall]
9995 *) Provide APACI --without-support option to be able to disable the build
9996 and installation of the support tools from the src/support/ area.
9997 Although its useful to have these installed per default we should provide
9998 a way to compile and install without them for backward-compatibility.
9999 [Ralf S. Engelschall]
10001 *) Add of the new APache eXtenSion (apxs) support tool for building and
10002 installing modules into an _already installed_ Apache package through the
10003 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
10004 this approach actually doesn't need the Apache source tree. The
10005 (APACI-installed) server package is enough, because this now includes the
10006 Apache C header files (PREFIX/include) and the new APXS tool
10007 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
10008 module authors to build their Apache modules _OUTSIDE_ the Apache source
10009 tree while avoiding them to fiddle around with the totally platform
10010 dependend way of compiling DSO files. The tool supports all ranges of
10011 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
10012 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
10013 on-the-fly generate a minimalistic Makefile and sample module for the
10014 first step to provide both a quick success event and to demonstrate the
10015 APXS mechanism to module authors. [Ralf S. Engelschall]
10017 *) Fix core dumps in use of CONNECT in proxy.
10018 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
10020 *) Modify the log directives in httpd.conf-dist files to use CustomLog
10021 so that users have examples of how CustomLog can be used.
10024 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
10025 the Apache distribution tree. Until Apache 1.3 there was no real
10026 out-of-the-box batch-capable build and installation procedure for the
10027 complete Apache package. This is now provided by a top-level "configure"
10028 script and a corresponding top-level "Makefile.tmpl" file. The goal is
10029 to provide a GNU Autoconf-style frontend which is capable to both drive
10030 the old src/Configure stuff in batch and additionally installs the
10031 package with a GNU-conforming directory layout. Any options from the old
10032 configuration scheme are available plus a lot of new options for flexibly
10033 customizing Apache. [Ralf S. Engelschall]
10035 *) The floating point ap_snprintf code wasn't threadsafe.
10036 Had to remove the HAVE_CVT macro in order to do threadsafe
10037 calling of the ?cvt() floating point routines. [Dean Gaudet]
10039 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
10041 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
10042 [Jim Jagielski] PR#1901
10044 *) BUG: Configure was using TCC and CC inconsistently. Make sure
10045 Configure knows which CC we are using. [Jim Jagielski]
10047 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
10048 was defined in a parent directory. [Lars Eilebrecht]
10050 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
10051 a generic printf-style routine that can call arbitrary output
10052 routines. Use this to replace http_bprintf.c. Add new routines
10053 psprintf(), pvsprintf() which allocate the exact amount of memory
10054 required for a string from a pool. Use psprintf() to clean up
10055 various bits of code which used ap_snprintf()/pstrdup().
10058 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
10059 ap_snprintf() has different semantics and formatting codes than
10060 snprintf(). [Dean Gaudet]
10062 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
10063 is necessary on at least Solaris where the /etc/rc?.d scripts
10064 are run with these signals ignored, and "SIG_IGN" settings are
10065 maintained across exec().
10066 [Rein Tollevik <reint sys.sol.no>] PR#2009
10068 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
10069 used instead of lstat() and thus this flag didn't work as expected.
10070 [Rein Tollevik <reint sys.sol.no>] PR#2010
10072 *) Fix the proxy pass-through feature of mod_rewrite for the case of
10073 existing QUERY_STRING now that mod_proxy was recently changed because of
10074 the new URL parsing stuff. [Ralf S. Engelschall]
10076 *) A few changes to scoreboard definitions which helps gcc generate
10077 better code. [Dean Gaudet]
10079 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
10080 be a signed bitfield. So mark a few bitfields as signed to
10081 ensure correct code. [Dean Gaudet]
10083 *) The default for HostnameLookups was changed to Off, but there
10084 was a problem and it wasn't taking effect. [Dean Gaudet]
10086 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
10089 *) After a SIGHUP the listening sockets in the parent weren't
10090 properly marked for closure on fork().
10091 [Jürgen Keil <jk tools.de>] PR#2000
10093 *) Allow %2F in two situations: 1) it is in the query part of the URI,
10094 therefore not exposed to %2F -> '/' translations and 2) the request
10095 is a proxy request, so we're not dealing with a local resource anyway.
10096 Without this, the proxy would fail to work for any URL's with
10097 %2f in them (occurs quite often in
10098 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
10100 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
10102 *) Make the shared object compilation command more portable by avoiding
10103 the direct combination of `-c' & `-o' which is not honored by some
10104 compilers like UnixWare's cc. [Ralf S. Engelschall]
10106 *) WIN32: the proxy was creating filenames missing the last four
10107 characters. While this normally doesn't stop anything from
10108 working, it can result in extra collisions.
10109 [Tim Costello <tjcostel socs.uts.edu.au>] PR#1890
10111 *) Now mod_proxy uses the response string (in addition to the response status
10112 code) from the already used FTP SIZE command to setup the Content-Length
10113 header if available. [Ralf S. Engelschall] PR#1183
10115 *) Reanimated the (still undocumented) proxy receive buffer size directive:
10116 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
10117 name was really too generic, added documentation for this directive to
10118 the mod_proxy.html and corrected the hyperlink to it in the
10119 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
10121 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
10122 faster [Martin Kraemer]
10124 *) Make Configure die when you give it an unknown command switch.
10127 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
10128 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
10129 and per default compiled support programs have manual pages - just to
10130 document our stuff a little bit more and to be able to do really
10131 Unix-like installations ;-) [Ralf S. Engelschall]
10133 *) Major cleanups to the Configure script to make it and its generated
10134 Makefiles again readable and maintainable: add SRCDIR option, removed
10135 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
10136 generated sections, consequently added Makefile headers with inheritance
10137 information, added subdir movement messages for easier following where
10138 the build process currently stays (more verbose then standard Make, less
10139 verbose than GNU make), same style to comments in the Configure script,
10140 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
10142 *) Add the new ApacheBench program "ab" to src/support/: This is derived
10143 from the ZeusBench benchmarking program and can be used to determine the
10144 response performance of an Apache installation. This version is
10145 officially licensed with Zeus Technology, Ltd. See the license agreement
10146 statements in <199803171224.NAA24547 en1.engelschall.com> in apache-core.
10147 [Ralf S. Engelschall]
10149 *) API: Various core functions that are definately not part of the API
10150 have been made static, and a few have been marked API_EXPORT. Still
10151 more have been marked CORE_EXPORT and are not intended for general
10152 use by modules. [Doug MacEachern, Dean Gaudet]
10154 *) mod_proxy was not clearing the Proxy-Connection header from
10155 requests; now it does. This did not violate any spec, however
10156 causes poor interactions when you are talking to remote proxies.
10157 [Marc Slemko] PR#1741
10159 *) Various cleanups to the command line interface and manual pages.
10160 [Ralf S. Engelschall]
10162 *) cfg_getline() was not properly handling lines that did not end
10163 with a line termination character. [Marc Slemko] PR#1869, 1909
10165 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
10167 *) Clean up some undocumented behavior of mod_setenvif related to
10168 "merging" two SetEnvIf directives when they match the same header
10169 and regex. Document that mod_setenvif will perform comparisons in
10170 the order they appear in the config file. Optimize mod_setenvif by
10171 doing more work at config time rather than at runtime.
10174 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
10175 to allow for modules to overrule them and to reduce redefinition
10176 warnings [Jim Jagielski]
10178 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
10181 *) Making the hard-coded cross-module function call mime_find_ct() (from
10182 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
10183 checking is really called even for proxy requests except for URLs with
10184 HTTP schemes (because there we can optimize by not running the type
10185 checking hooks due to the fact that the proxy gets the MIME Content-type
10186 from the remote host later). This change cleans up mod_mime by removing
10187 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
10188 especially unbundles mod_proxy and mod_mime. This way they both now can
10189 be compiled as shared objects and are no longer tied together.
10190 [Ralf S. Engelschall]
10192 *) util.c cleanup and speedup. [Dean Gaudet]
10194 *) API: Clarification, pstrndup() will always copy n bytes of the source
10195 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
10197 *) Mark module command_rec and handler_rec structures const so that they
10198 end up in the read-only data section (and are friendlier to systems
10199 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
10201 *) Add check to the "Port" directive to make sure the specified
10202 port is in the appropriate range. [Ben Hyde]
10204 *) Performance improvements to invoke_handler().
10205 [Dmitry Khrustalev <dima bog.msu.su>]
10207 *) Added support for building shared objects even for library-style modules
10208 (which are built from more than one object file). This now provides the
10209 ability to build mod_proxy as a shared object module. Additionally
10210 modules like mod_example are now also supported for shared object
10211 building because the generated Makefiles now no longer assume there is at
10212 least one statically linked module. [Ralf S. Engelschall]
10214 *) API: Clarify usage of content_type, handler, content_encoding,
10215 content_language and content_languages fields in request_rec. They
10216 must always be lowercased; and the strings pointed to shouldn't
10217 be modified (you must copy them to modify them). Fix a few bugs
10218 related to this. [Dean Gaudet]
10220 *) API: Clarification: except for RAW_ARGS, all command handlers can
10221 treat the char * parameters as permanent, and modifiable. There
10222 is no need to pstrdup() them. Clean up some needless pstrdup().
10225 *) Now mod_so keeps track of which module shared objects with which names
10226 are loaded and thus avoids multiple loading and unloading and irritating
10227 error_log messages. [Ralf S. Engelschall]
10229 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
10230 environment variable in the apache core. But that tweaking interferes
10231 with mod_setenv. So don't tweak if the user has specified an explicit
10232 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888
10234 *) rputs() did not calculate r->sent_bodyct properly.
10235 [Siegmund Stirnweiss <siegst kat.ina.de>] PR#1900
10237 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
10238 name, or left unset if this value is unavailable. Apache was setting
10239 it to the IP address when unavailable.
10240 [Tony Finch <fanf demon.net>] PR#1925
10242 *) Various improvements to the configuration and build support for compiling
10243 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
10244 OSF1 support with GCC and vendor compilers was added. This way shared
10245 object support is now provided out-of-the-box for FreeBSD, Linux,
10246 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
10247 [Ralf S. Engelschall]
10249 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
10250 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
10251 and USE_OS2_SCOREBOARD. [Dean Gaudet]
10253 *) Fix one more special locking problem for RewriteMap programs in
10254 mod_rewrite: According to the documentation of flock(), "Locks are on
10255 files, not file descriptors. That is, file descriptors duplicated
10256 through dup(2) or fork(2) do not result in multiple instances of a lock,
10257 but rather multiple references to a single lock. If a process holding a
10258 lock on a file forks and the child explicitly unlocks the file, the
10259 parent will lose its lock.". To overcome this we have to make sure the
10260 RewriteLock file is opened _AFTER_ the childs were spawned which is now
10261 the case by opening it in the child_init instead of the module_init API
10262 hook. [Ralf S. Engelschall] PR#1029
10264 *) Change to Location and LocationMatch semantics. LocationMatch no
10265 longer lets a single slash match multiple adjacent slashes in the
10266 URL. This change is for consistency with RewriteRule and
10267 AliasMatch. Multiple slashes have meaning in URLs that they do
10268 not have in (some) filesystems. Location on the other hand can
10269 be considered a shorthand for a more complicated regex, and it
10270 does match multiple slashes with a single slash -- which is
10271 also consistent with the Alias directive.
10272 [Dean Gaudet] related PR#1440
10274 *) Fix bug with mod_mime_magic causing certain files, including files
10275 of length 0, to result in no response from the server.
10278 *) The Configure script now generates src/include/ap_config.h which
10279 contains the set of defines used when Apache is compiled on a platform.
10280 This file can then be included by external modules before including
10281 any Apache header files in case they are being built separately from
10282 Apache. Along with this change, a couple of minor changes were
10283 made to make Apache's #defines coexist peacefully with any autoconf
10284 defines an external module might have. [Rasmus Lerdorf]
10286 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
10287 but without any RewriteXXXXX directives. Here mod_rewrite is given no
10288 chance by the API to initialize its per-server configuration and thus
10289 receives the wrong one from the main server. This is now avoided by
10290 remembering the server together with the config structure while
10291 configuring and later assuming there is no config when we see a
10292 difference between the remembered server and the one calling us.
10293 [Ralf S. Engelschall] PR#1790
10295 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
10296 is automatically disabled under configure time when the dbm_xxx functions
10297 are not available. Second, two heavy source code errors in the DBM

10301 *) Now all configuration files support Unix-style line-continuation via
10302 the trailing backslash ("\") character. This enables us to write down
10303 complex or just very long directives in a more readable way. The
10304 backslash character has to be really the last character before the
10305 newline and it has not been prefixed by another (escaping) backslash.

10323 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
10324 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
10325 up static content only servers. Or it may fail unpredictably.

10328 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
10331 *) API: Rewrite of absoluteURI handling, and in particular how
10332 absoluteURIs match vhosts. Unless a request is a proxy request, a
10333 "http://host" url is treated as if a similar "Host:" header had been
10334 supplied. This change was made to support future HTTP/1.x protocols
10335 which may require clients to send absoluteURIs for all requests.
10337 In order to achieve this change subtle changes were made to the API. In a
10338 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
10339 that the unmodified uri can be retrieved easily. r->proxyreq is not set
10340 by the core, modules must set it during the post_read_request or
10341 translate_names phase.
10343 Plus changes to the virtualhost test suite for absoluteURI testing.
10345 This fixes several bugs with the proxy proxying requests to vhosts
10346 managed by the same httpd.
10349 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
10350 code from mod_rewrite. The vhost matching is now performed by a
10351 globally available function matches_request_vhost(). [Dean Gaudet]

10367 *) API: A new source module main/util_uri.c; It contains a routine
10368 parse_uri_components() and friends which breaks a URI into its component
10369 parts. These parts are stored in a uri_components structure called
10370 parsed_uri within each request_rec, and are available to all modules.
10371 Additionally, an unparse routine is supplied which re-assembles the URI
10372 components back to an URI, optionally hiding the username:password@ part
10373 from ftp proxy requests, and other useful routines. Within the structure,
10374 you find on a ready-for-use basis:
10375 scheme; /* scheme ("http"/"ftp"/...) */
10376 hostinfo; /* combined [user[:password]@]host[:port] */
10377 user; /* user name, as in http://user:passwd@host:port/ */
10378 password; /* password, as in http://user:passwd@host:port/ */
10379 hostname; /* hostname from URI (or from Host: header) */
10380 port_str; /* port string (integer representation is in "port") */
10381 path; /* the request path (or "/" if only scheme://host was given) */
10382 query; /* Everything after a '?' in the path, if present */
10383 fragment; /* Trailing "#fragment" string, if present */
10384 This is meant to serve as the platform for *BIG* savings in
10385 code complexity for the proxy module (and maybe the vhost logic).
10388 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
10389 ${map:key}) available for all location where a string is created in
10390 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

10430 type but with a special post-processing for the looked-up value: It
10431 parses it into alternatives according to `|' chars and then only one
10432 particular alternative is chosen randomly (this is an essential
10433 functionality needed for balancing between backend-servers when using
10434 Apache as a Reverse Proxy. The looked up value here is a list of
10435 servers). Second, `int' with the built-in maps named `tolower' and
10436 `toupper' which can be used to map URL parts to a fixed case (this is an
10437 essential feature to fix the case of server names when doing mass
10438 virtual-hosting with the help of mod_rewrite instead of using

10596 references in Makefiles have been changed to the simpler -Iinclude
10597 instead. In addition to simplifying the build a little bit, this
10598 also makes it clear when a module is referencing something in a
10599 other than kosher manner (e.g., the proxy including mod_mime.h).
10600 Module-private header files (the proxy, mod_mime, the regex library,

10631 *) mod_unique_id was erroneously generating a second unique id when
10632 an internal redirect occured. Such redirects occur, for example,
10633 when processing a DirectoryIndex match. [Dean Gaudet]
10635 *) API: table_add, table_merge, and table_set include implicit pstrdup()
10636 of the key and value. But in many cases this is not required
10637 because the key/value is a constant, or the value has been built
10638 by pstrcat() or other similar means. New routines table_addn,
10639 table_mergen, and table_setn have been added to the API, these
10640 routines do not pstrdup() their arguments. The core code and
10641 standard modules were changed to take advantage of these routines.
10642 The resulting server is up to 20% faster in some situations.
10644 Note that it is easy to get code subtly wrong if you pass a key/value
10645 which is in a pool other than the pool of the table. The only
10646 safe thing to do is to pass key/values which are in the pool of
10647 the table, or in one of the ancestors of the pool of the table.
10648 i.e. if the table is part of a subrequest, a value from the main
10649 request's pool is OK since the subrequest pool is a sub_pool of the
10650 main request's pool (and therefore has a lifespan at most as long as
10651 the main pool). There is debugging code which can detect improper
10652 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
10653 [Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet]

10669 have been writing to use table as if it were an opaque type, but even
10670 some standard modules got this wrong. By changing the definition
10671 to "typedef struct table table" module authors will receive compile
10672 time warnings that they're doing the wrong thing. This change
10673 facilitates future changes with more sophisticated table

10678 library routines. [Ken Coar, Rasmus Lerdorf]
10680 *) WIN32: mod_speling is now available on the Win32 platform.
10683 *) For clarity the following compile time definition was changed:
10685 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
10687 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
10688 and not be a general notice that the OS has mmap(). Now the
10689 HAVE_MMAP/SHMGET #defines strictly are informational that the
10690 OS has that method of shared memory; the type to use for
10691 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
10692 and USE_SHMGET_SCOREBOARD). This allows outside modules to
10693 determine if shared memory is available and allows Apache
10694 to determine the best method to use for the scoreboard.

10786 *) For maximum portability, the environment passed to CGIs should
10787 only contain variables whose names match the regex
10788 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
10789 underscores over any character outside the regex. This
10790 affects HTTP_* variables, in a way that should be backward
10791 compatible for all the standard headers; and affects variables
10792 set with SetEnv/BrowserMatch and similar directives.
10795 *) mod_speling returned incorrect HREF's when an ambigous match

10831 *) SECURITY: Numerous changes to mod_imap in a general cleanup
10832 including fixing a possible buffer overflow. [Dean Gaudet]
10834 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
10835 (connections are not dropped). Code can handle graceful restarts
10836 (but there is as yet no way to signal this to Apache). Various
10837 other cleanups. [Paul Sutton]
10839 *) The aplog_error changes specific to 1.3 introduced a buffer
10840 overrun in the (now legacy) log_printf function. Fixed.
10843 *) mod_digest didn't properly deal with proxy authentication. It
10844 also lacked a case-insensitive comparision of the "Digest"

10879 [Ben Reser <breser regnow.com>] PR#1366
10881 *) The bputc() macro was not properly integrated with the chunking
10882 code; in many cases modules using bputc() could cause completely
10883 bogus chunked output. (Typically this will show up as problems
10884 with Internet Explorer 4.0 reading a page, but other browsers
10885 having no problem.) [Dean Gaudet]
10887 *) Create LARGE_WRITE_THRESHOLD define which determines how many
10888 bytes have to be supplied to bwrite() before it will consider
10889 doing a writev() to assemble multiple buffers in one system
10890 call. This is critical for modules such as mod_include,
10891 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
10892 strings in some cases. The result would be extra effort
10893 setting up writev(), and in many cases extra effort building
10894 chunks. The default is 31, it can be overriden at compile
10895 time. [Dean Gaudet]

11011 *) PORT: Recent changes made it necessary to add explicit prototype
11012 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
11014 *) It was necessary to distinguish between resources which are
11015 allocated in the parent, for cleanup in the parent, and resources
11016 which are allocated in each child, for cleanup in each child.
11017 A new pool was created which is passed to the module child_init
11018 and child_exit functions; modules are free to register per-child
11019 cleanups there. This fixes a bug with reliable piped logs.
11022 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
11023 unless it was also doing FancyIndexes, but it displayed the
11024 HeaderName file at the top under all circumstances. It now shows
11025 the ReadmeName file for simple indices, too, as it should.
11028 *) http_core was mmap()ing even in cases where it wasn't going to
11029 read the file. [Ben Hyde <bhyde gensym.com>]
11031 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
11032 Now the rewriting engine (the heart of mod_rewrite) is organized more
11033 straight-forward, first time well documented and reduced to the really
11034 essential parts. All redundant cases were stripped off and processing now
11035 is the same for both per-server and per-directory context with only a
11036 minimum difference (the prefix stripping in per-dir context). As a
11037 side-effect some subtle restrictions and two recently discovered problems
11038 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
11039 context and restrictions on the substitution URL on redirects.
11040 Additionally some minor source cleanups were done.

11197 *) TestCompile was not passing $LIBS [Dean Gaudet]
11199 *) Makefile.tmpl was not using $CFLAGS in the link phase.
11202 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
11203 rudimentary memory debugger which can be used on live servers with
11204 low impact -- it sets all allocated and freed memory bytes to 0xa5.
11205 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
11206 and free() for each object. This is far more expensive and should
11207 only be used for testing with tools such as Electric Fence and
11208 Purify. See main/alloc.c for more details. [Dean Gaudet]
11210 *) Configure uses a sh trap and didn't set its exitcode properly.

11214 explicitly lists the ip:port pairs that are to be used for name-vhosts.
11215 From a given ip:port, regardless what the Host: header is, you can
11216 only reach the vhosts defined on that ip:port. The precedence of
11217 vhosts was reversed to match other precedences in the config --
11218 the earlier vhosts override the later vhosts. All vhost matching was
11219 moved into http_vhost.[ch]. [Dean Gaudet]
11221 *) ap_inline can be used to force inlining. GNUC __attribute__() can
11222 be used for whatever reason is appropriate (i.e. format() warnings
11223 for printf style functions). Both are enabled only with
11224 gcc >= 2.7.x (so that we have fewer support issues with older

11239 files have been read so you will be able to see initial error
11240 messages. After that all errors are logged in the error_log.
11241 This makes it more convenient to start apache via rsh, ssh,

11263 *) RedirectMatch was not properly escaping the result (PR#1155). Also
11264 "RedirectMatch /advertiser/(.*) $1" is now permitted.

11294 *) API: the short_score record has been split into two pieces, one which
11295 the parent writes on, and one which the child writes on. As part of
11296 this change the get_scoreboard_info() function was removed, and
11297 scoreboard_image was exported. This change fixes a race condition
11298 in file based scoreboard systems, and speeds up changes involving the
11299 scoreboard in earlier 1.3 development. [Dean Gaudet]
11301 *) API: New register_other_child() API (see http_main.h) which allows
11302 modules to register children with the parent for maintenance. It
11303 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
11305 *) API: New piped_log API (see http_log.h) which implements piped logs,
11306 and will use register_other_child to implement reliable piped logs
11307 when it is available. The reliable piped logs part can be disabled
11308 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
11309 logs is only available on Unix. [Dean Gaudet]
11311 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
11312 meets_conditions(). This allows conditional HTTP selection to be
11313 handled separately from the storing of the header fields, and provides
11314 the ability for CGIs to set their own ETags for conditional checking.
11315 [Ken Coar, Roy Fielding] PR#895
11317 *) Changes to mod_log_config to allow naming of format strings.
11318 Format nicknames are defined with "LogFormat fmt nickname", and can
11319 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
11322 *) New module, "mod_speling", which can help find files even when
11323 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
11325 *) API: New function child_terminate() triggers the child process to
11326 exit, while allowing the child finish what it needs to for the
11327 current request first.
11328 [Doug MacEachern, Alexei Kosut]
11330 *) Windows now defaults to using full status reports with mod_status.
11331 [Alexei Kosut] PR #1094
11333 *) *Really* disable all mod_rewrite operations if the engine is off.
11334 Some things (like RewriteMaps) were checked/performed even if they
11335 weren't supposed to be. [Ken Coar] PR #991
11337 *) Implement a new timer scheme which eliminates the need to call alarm() all
11338 the time. Instead a counter in the scoreboard for each child is used to
11339 show when the child has made forward progress. The parent samples this
11340 counter every scoreboard maintenance cycle, and issues SIGALRM if no
11341 progress has been made in the timeout period. This reduces the static
11342 request best-case syscall count to 22 from 29. This scheme is only
11343 used by systems with memory-based scoreboards. [Dean Gaudet]
11345 *) The proxy now properly handles CONNECT requests which are sent
11346 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
11348 *) A script called apachectl has been added to the support
11349 directory. This script allows you to do things such as
11350 "apachectl start" and "apachectl restart" from the command
11351 line. [Marc Slemko]
11353 *) Modules and core routines are now put into libraries, which
11354 simplifies the link line tremendously (among other advantages).
11357 *) Some of the MD5 names defined in Apache have been renamed to have
11358 an `ap_' prefix to avoid conflicts with routines supplied by
11359 external libraries. [Ken Coar]
11361 *) Removal of mod_auth_msql.c from the distribution. There are many
11362 other options for databases today. Rather than offer one option,
11363 offer none at this time. mod_auth_msql and other SQL database
11364 authentication modules can be found at the Apache Module Registry.
11365 http://modules.apache.org/ It would be nice to offer a generic
11366 mod_auth_sql option in the near future.
11368 *) PORT: BeOS support added [Alexei Kosut]
11370 *) Configure no longer accepts the -make option, since it creates
11371 Makefile on the fly based on Makefile.tmpl and Configuration.
11373 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
11374 of forcibly killing off all its processes and exiting without
11375 cleaning up. [Alexei Kosut]
11377 *) API: A new field in the request_rec, r->mtime, has been added to
11378 avoid gratuitous parsing of date strings. It is intended to hold
11379 the last-modified date of the resource (if applicable). An
11380 update_mtime() routine has also been added to advance it if
11381 appropriate. [Roy Fielding, Ken Coar]
11383 *) SECURITY: If a htaccess file can not be read due to bad permissions,
11384 deny access to the directory with a HTTP_FORBIDDEN. The previous
11385 behavior was to ignore the htaccess file if it could not be read.
11386 This change may make some setups with unreadable htaccess files
11387 stop working. [Marc Slemko] PR#817
11389 *) Add aplog_error() providing a mechanism to define levels of
11390 verbosity to the server error logging. This addition also provides
11391 the ability to log errors using syslogd. Error logging is configurable
11392 on a per-server basis using the LogLevel directive. Conversion
11393 of log_*() in progress. [Randy Terbush]
11395 *) Further enhance aplog_error() to not log filename, line number, and
11396 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
11398 *) WIN32: Canonicalise filenames under Win32. Short filenames are
11399 converted to long ones. Backslashes are converted to forward
11400 slashes. Case is converted to lower. Parts of URLs that do not
11401 correspond to files are left completely alone. [Ben Laurie]
11403 *) PORT: 2 new OSs added to the list of ports:
11404 Encore's UMAX V: Arieh Markel <amarkel encore.com>
11405 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
11407 *) Add the server version (SERVER_VERSION macro) to the "server
11408 configured and running" entry in the error_log. Also build an
11409 object file at link-time that contains the current time
11410 (SERVER_BUILT global const char[]), and include that in the
11411 message. [Ken Coar]
11413 *) Set r->headers_out when sending responses from the proxy.
11414 This fixes things such as the logging of headers sent from
11415 the proxy. [Marc Slemko] PR#659
11417 *) support/httpd_monitor is no longer distributed because the
11418 scoreboard should not be file based if at all possible. Use
11419 mod_status to see current server snapshot.
11421 *) (set_file_slot): New function, allowing auth directives to be
11422 independent of the server root, so the server documents can be
11423 moved to a different directory or machine more easily.
11424 [David J. MacKenzie]
11426 *) If no TransferLog is given explicitly, decline
11427 to log. This supports coexistence with other logging modules,
11428 such as the custom one that UUNET uses. [David J. MacKenzie]
11430 *) Check for titles in server-parsed HTML files.
11431 Ignore leading newlines and returns in titles. The old behavior
11432 of replacing a newline after <title> with a space causes the
11433 title to be misaligned in the listing. [David J. MacKenzie]
11435 *) Change mod_cern_meta to be configurable on a per-directory basis.
11436 [David J. MacKenzie]
11438 *) Add 'Include' directive to allow inclusion of configuration
11439 files within configuration files. [Randy Terbush]
11441 *) Proxy errors on connect() are logged to the error_log (nothing
11442 new); now they include the IP address and port that failed
11443 (*that's* new). [Ken Coar, Marc Slemko] PR#352
11445 *) Various architectures now define USE_MMAP_FILES which causes
11446 the server to use mmap() for static files. There are two
11447 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
11448 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
11449 number of bytes written in one cycle from a single mmap()d object,
11450 default 32768). [Dean Gaudet]
11452 *) API: Added post_read_request API phase which is run right after reading
11453 the request from a client, or right after an internal redirect. It is
11454 useful for modules setting environment variables that depend only on
11455 the headers/contents of the request. It does not run during subrequests
11456 because subrequests inherit pretty much everything from the main
11457 request. [Dean Gaudet]
11459 *) Added mod_unique_id which is used to generate a unique identifier for
11460 each hit, available in the environment variable UNIQUE_ID.
11463 *) init_modules is now called after the error logs have been opened. This
11464 allows modules to emit information messages into the error logs.
11467 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11468 information for case where proxy module is not available. [Marc Slemko]
11470 *) PORT: Apache has need for mutexes to serialize its children around
11471 accept. In prior versions either fcntl file locking or flock file
11472 locking were used. The method is chosen by the definition of
11473 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
11474 and FLOCK for flock(). New options have been added:
11475 - SYSVSEM to use System V style semaphores
11476 - PTHREAD to use POSIX threads (appears to work on Solaris only)
11477 - USLOCK to use IRIX uslock
11478 Based on timing various techniques, the following changes were made
11480 - Linux 2.x uses flock instead of fcntl
11481 - Solaris 2.x uses pthreads
11482 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
11483 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
11484 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
11485 Martijn Koster <m.koster pobox.com>]
11487 *) PORT: The semantics of accept/select make it very desirable to use
11488 mutexes to serialize accept when multiple Listens are in use. But
11489 in the case where only a single socket is open it is sometimes
11490 redundant to serialize accept(). Not all unixes do a good job with
11491 potentially dozens of children blocked on accept() on the same
11492 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
11493 the server will avoid serialization when listening on only one socket,
11494 and use serialization when listening on multiple sockets.
11495 [Dean Gaudet] PR#467
11497 *) Configure changes: TestLib replaced by TestCompile, which has
11498 some additional capability (such as doing a sanity check of
11499 the compiler and flags selected); the version of Solaris is now
11500 available via the #define value of SOLARIS2; IRIX n32bit libs
11501 now supported and selectable by new Configuration Rule: IRIXN32;
11502 We no longer default to -O2 optimization. [Jim Jagielski]
11504 *) Updated Configure: Configuration now uses AddModule to specify
11505 module source or binary file location, relative to src directory.
11506 Modules can be dropped into modules/extra, or in their own
11507 directory, and modules can come with a Makefile or Configure can
11508 create one. Modules can add compiler or library information to
11509 generated Makefiles. [Paul Sutton]
11511 *) Source core re-organisation: distributed modules are now in
11512 modules/standard. All other source code is in main. OS-specific
11513 code is in os/{unix,emx,win32} directories. [Paul Sutton]
11515 *) mod_browser has been removed, since it's replaced by mod_setenvif.
11518 *) Fix another long-standing bug in sub_req_lookup_file where it would
11519 happily skip past access checks on subdirectories looked up with
11520 relative paths. (It's used by mod_dir, mod_negotiation,
11521 and mod_include.) [Dean Gaudet]
11523 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
11524 N is the number of <Directory> sections, and M is the number of
11525 components in the filename of an object.
11527 To achieve this optimization the following config changes were made:
11528 - Wildcards (* and ?, not the regex forms) in <Directory>s,
11529 <Files>s, and <Location>s now treat a slash as a special
11530 character. For example "/home/*/public_html" previously would
11531 match "/home/a/andrew/public_html", now it only matches things
11532 like "/home/bob/public_html". This mimics /bin/sh behaviour.
11533 - It's possible now to use [] wildcarding in <Directory>, <Files>
11535 - Regex <Directory>s are applied after all non-regex <Directory>s.
11539 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
11540 and corrupted paths. [Dean Gaudet]
11542 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
11543 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
11544 be accessed now via backreferences $1..$9 in RewriteConds test-against
11545 strings in addition to RewriteRules subst string. Second the grouped
11546 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
11547 via backreferences %1..%9 both in following RewriteCond test-against
11548 strings and RewriteRules subst string. This provides maximum flexibility
11549 through the use of backreferences.
11550 Additionally the rewriting engine was cleaned up by putting common
11551 code to the new expand_backrefs_inbuffer() function.
11552 [Ralf S. Engelschall]
11554 *) When merging the main server's <Directory> and <Location> sections into
11555 a vhost, put the main server's first and the vhost's second. Otherwise
11556 the vhost can't override the main server. [Dean Gaudet] PR#717
11558 *) The <Directory> code would merge and re-merge the same section after
11559 a match was found, possibly causing problems with some modules.
11562 *) ip-based vhosts are stored and queried using a hashing function, which
11563 has been shown to improve performance on servers with many ip-vhosts.
11564 Some other changes had to be made to accommodate this:
11565 - the * address for vhosts now behaves like _default_
11566 - the matching process now is:
11567 - match an ip-vhost directly via hash (possibly matches main
11569 - if that fails, just pretend it matched the main server
11570 - if so far only the main server has been matched, perform
11571 name-based lookups (ServerName, ServerAlias, ServerPath)
11572 *only on name-based vhosts*
11573 - if they fail, look for _default_ vhosts
11574 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
11576 *) dbmmanage overhaul:
11577 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
11578 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
11579 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
11580 - provide better seed for rand
11581 - prompt for password as per getpass(3) (turn off echo, read from
11583 - use "newstyle" crypt based on $Config{osname} ($^O)
11584 - will not add a user if already in database, use new `update' command
11586 - added `check' command to check a users' password
11587 - added `import' command to convert existing password text-files or
11588 dbm files exported with `view'
11589 - more descriptive usage, general cleanup, 'use strict' clean, etc.
11592 *) Added psocket() which is a pool form of socket(), various places within
11593 the proxy weren't properly blocking alarms while registering the cleanup
11594 for its sockets. bclose() now uses pclose() and pclosesocket(). There
11595 was a bug where the client socket was being close()d twice due a still
11596 registered cleanup. [Dean Gaudet]
11598 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
11601 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
11602 [Jason Venner <jason idiom.com>] PR#667
11604 *) Enable ``=""'' for RewriteCond directives to match against
11605 the empty string. This is the preferred way instead of ``^$''.
11606 [Ralf S. Engelschall]
11608 *) Fixed an infinite loop in mod_imap for references above the server root
11609 [Dean Gaudet] PR#748
11611 *) mod_proxy now has a ReceiveBufferSize directive, similar to
11612 SendBufferSize, so that the TCP window can be set appropriately
11613 for LFNs. [Phillip A. Prindeville]
11615 *) mod_browser has been replaced by the more general mod_setenvif
11616 (courtesy of Paul Sutton). BrowserMatch* directives are still
11617 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
11618 UnSetEnvIfZero directives. [Ken Coar]
11620 *) "HostnameLookups double" forces double-reverse DNS to succeed in
11621 order for remote_host to be set (for logging, or for the env var
11622 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
11625 *) mod_access overhaul:
11626 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
11627 and cidr syntax (i.e. 10.1.0.0/16). PR#762
11628 - Critical path was sped up by pre-computing a few things at config time.
11629 - The undocumented syntax "allow user-agents" was removed,
11630 the replacement is "allow from env=foobar" combined with mod_browser.
11631 - When used with hostnames it now forces a double-reverse lookup
11632 no matter what the directory settings are. This double-reverse
11633 doesn't affect any of the other routines that use the remote
11634 hostname. In particular it's still passed to CGIs and the log
11635 without the double-reverse check. Related PR#860.
11638 *) When a large bwrite() occurs (larger than the internal buffer size),
11639 while there is already something in the buffer, apache will combine
11640 the large write and the buffer into a single writev(). (This is
11641 in anticipation of using mmap() for reading files.)
11644 *) In obscure cases where a partial socket write occurred while chunking,
11645 Apache would omit the chunk header/footer on the next block. Cleaned
11646 up other bugs/inconsistencies in error conditions in buff.c. Fixed
11647 a bug where a long pause in DNS lookups could cause the last packet
11648 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
11650 *) API: Added child_exit function to module structure. This is called
11651 once per "heavy-weight process" just before a server child exit()'s
11652 e.g. when max_requests_per_child is reached, etc.
11653 [Doug MacEachern, Dean Gaudet]
11655 *) mod_include cleanup showed that handle_else was being used to handle
11656 endif. It didn't cause problems, but it was cleaned up too.
11659 *) mod_cern_meta would attempt to find meta files for the directory itself
11660 in some cases, but not in others. It now avoids it in all cases.
11663 *) mod_mime_magic would core dump if there was a decompression error.
11664 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
11666 *) PORT: some variants of DGUX require -lsocket -lnsl
11667 [Alexander L Jones <alex systems-options.co.uk>] PR#732
11669 *) mod_autoindex now allows sorting of FancyIndexed directory listings
11670 by the various fields (name, size, et cetera), either in ascending
11671 or descending order. Just click on the column header. [Ken Coar]
11673 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
11674 CPUs like the Alpha. Apache still stores ints in pointers, but that's
11675 the relatively safe direction. [Dean Gaudet] PR#344
11677 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
11678 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
11680 *) child_main avoids an unneeded call to select() when there is only one
11681 listening socket. [Dean Gaudet]
11683 *) In the event that the server is starved for idle servers it will
11684 spawn 1, then 2, then 4, ..., then 32 servers each second,
11685 doubling each second. It'll also give a warning in the errorlog
11686 since the most common reason for this is a poor StartServers
11687 setting. The define MAX_SPAWN_RATE can be used to raise/lower
11688 the maximum. [Dean Gaudet]
11690 *) Apache now provides an effectively unbuffered connection for
11691 CGI scripts. This means that data will be sent to the client
11692 as soon as the CGI pauses or stops output; previously, Apache would
11693 buffer the output up to a fixed buffer size before sending, which
11694 could result in the user viewing an empty page until the CGI finished
11695 or output a complete buffer. It is no longer necessary to use an
11696 "nph-" CGI to get unbuffered output. Given that most CGIs are written
11697 in a language that by default does buffering (e.g. perl) this
11698 shouldn't have a detrimental effect on performance.
11700 "nph-" CGIs, which formerly provided a direct socket to the client
11701 without any server post-processing, were not fully compatible with
11702 HTTP/1.1 or SSL support. As such they would have had to implement
11703 the transport details, such as encryption or chunking, in order
11704 to work properly in certain situations. Now, the only difference
11705 between nph and non-nph scripts is "non-parsed headers".

11708 *) If a BUFF is switched from buffered to unbuffered reading the first
11709 bread() will return whatever remained in the buffer prior to the

11712 Changes with Apache 1.3a1
11714 *) Added another Configure helper script: TestLib. It determines
11715 if a specified library exists. [Jim Jagielski]
11717 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
11718 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
11721 *) PORT: Some architectures use size_t for various lengths in network
11722 functions such as accept(), and getsockname(). The definition
11723 NET_SIZE_T is used to control this. [Dean Gaudet]
11725 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
11726 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
11727 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
11729 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
11730 [Igor N Kovalenko <infoh mail.wplus.net>]
11732 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11733 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11734 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

11773 mod_rewrite more thread-safe for NT port and fixed problem when creating
11774 an empty query string via "xxx?".
11775 This update also removes the copyright of Ralf S. Engelschall,
11776 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
11777 exclusively copyrighted by the Apache Group now. This happened because
11778 the author now has gifted mod_rewrite exclusively to the Apache Group and
11779 no longer maintains an external version.
11780 [Ralf S. Engelschall]
11782 *) API: Added child_init function to module structure. This is called
11783 once per "heavy-weight process" before any requests are handled.
11784 See http_config.h for more details. [Dean Gaudet]
11786 *) Anonymous_LogEmail was logging on each subrequest.
11787 [Dean Gaudet] PR#421, 868
11789 *) API: Added is_initial_req() which tests if the request being
11790 processed is the initial request, or a subrequest.
11793 *) Extended SSI (mod_include) now handles additional relops for
11794 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
11796 *) Configure fixed to correctly propagate user-selected options and
11797 settings (such as CC and OPTIM) to Makefiles other than
11798 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
11800 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
11801 directory indices to start with the contents of the HeaderName file
11802 if there is one. If there isn't one, the behaviour is unchanged.
11803 [Ken Coar, Roy Fielding, Andrey A. Chernov]
11805 *) WIN32: Modules can now be dynamically loaded DLLs using the
11806 LoadModule/LoadFile directives. Note that module DLLs must be
11807 compiled with the multithreaded DLL version of the runtime library.
11808 [Alexei Kosut and Ben Laurie]
11810 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
11811 This allows the admin to completely remove automatic indexing
11812 from the server, while still supporting the basic functions of
11813 trailing-slash redirects and DirectoryIndex files. Note that if
11814 you're carrying over an old Configuration file and you use directory
11815 indexing then you'll want to add:
11817 Module autoindex_module mod_autoindex.o
11819 before mod_dir in your Configuration. [Dean Gaudet]
11821 *) popendir/pclosedir created to properly protect directory scanning.
11822 [Dean Gaudet] PR#525
11824 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
11825 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
11826 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
11829 *) The AccessFileName directive can now take more than one filename.
11830 ["Lou D. Langholtz" <ldl usi.utah.edu>]
11832 *) The new mod_mime_magic can be used to "magically" determine the type
11833 of a file if the extension is unknown. Based on the unix file(1)
11834 command. [Ian Kluft <ikluft cisco.com>]
11836 *) We now determine and display the time spent processing a
11837 request if desired. [Jim Jagielski]
11839 *) mod_status: PID field of "dead" child slots no longer displays
11840 main httpd process's PID. [Jim Jagielski]
11842 *) Makefile.nt added - to build all the bits from the command line:
11843 nmake -f Makefile.nt
11844 Doesn't yet work properly. [Ben Laurie]
11846 *) Default text of 404 error is now "Not Found" rather than the
11847 potentially misleading "File Not Found". [Ken Coar]
11849 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
11850 for the net if we require people that actually need this data to
11851 enable it. [Linus Torvalds]
11853 *) directory_walk() is an expensive function, keep a little more state to
11854 avoid needless string counting. Add two new functions make_dirstr_parent
11855 and make_dirstr_prefix which replace all existing uses of make_dirstr.
11856 The new functions are a little less general than make_dirstr, but
11857 work more efficiently (less memory, less string counting).
11860 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
11861 to LDFLAGS) to avoid complications with lex rules in make files.
11862 [Dean Gaudet] PR#372
11864 *) run_method optimized to avoid needless scanning over NULLs in the
11865 module list. [Dean Gaudet]
11867 *) Revamp of (unix) scoreboard management code such that it avoids
11868 unnecessary traversals of the scoreboard on each hit. This is
11869 particularly important for high volume sites with a large
11870 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
11871 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
11872 httpd.h. [Dean Gaudet]
11874 *) In configurations using multiple Listen statements it was possible for
11875 busy sockets to starve other sockets of service. [Dean Gaudet]
11877 *) Added hook so standalone_main can be replaced at compile time
11878 (define STANDALONE_MAIN)
11881 *) Lowest-level read/write functions in buff.c will be replaced with
11882 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
11883 compile time. The default sfio discipline will behave as apache
11884 would without sfio compiled in.
11887 *) Enhance UserDir directive (mod_userdir) to accept a list of
11888 usernames for the 'disable' keyword, and add 'enable user...' to
11889 selectively *en*able userdirs if they're globally disabled.
11892 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
11893 will work with Netscape dbm files. (dbmmanage will probably not
11894 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
11896 *) Add a ListenBacklog directive to control the backlog parameter
11897 passed to listen(). Also change the default to 511 from 512.
11900 *) API: A new handler response DONE which informs apache that the
11901 request has been handled and it can finish off quickly, similar to
11902 how it handles errors. [Rob Hartill]
11904 *) Turn off chunked encoding after sending terminating chunk/footer
11905 so that we can't do it twice by accident. [Roy Fielding]
11907 *) mod_expire also issues Cache-Control: max-age headers.
11910 *) API: Added kill_only_once option for free_proc_chain so that it won't
11911 aggressively try to kill off specific children. For fastcgi.
11912 [Stanley Gambarin <gambarin OpenMarket.com>]
11914 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
11916 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
11917 When used together, these cause mod_dir to emit HEIGHT and WIDTH
11918 attributes in the FancyIndexing IMG tags. [Ken Coar]
11920 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
11922 *) PORT: Added Windows NT support
11923 [Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
11925 Changes with Apache 1.2.6
11927 *) mod_include when using XBitHack Full would send ETags in addition to
11928 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
11929 [Dean Gaudet] PR#1133
11931 *) SECURITY: When a client connects to a particular port/addr, and
11932 gives a Host: header ensure that the virtual host requested can
11933 actually be reached via that port/addr. [Ed Korthof <ed organic.com>]
11935 *) Support virtual hosts with wildcard port and/or multiple ports
11936 properly. [Ed Korthof <ed organic.com>]
11938 *) Fixed some case-sensitivity issues according to RFC2068.
11941 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
11942 and mod_include.c. [Dean Gaudet]
11944 *) Variable 'cwd' was being used pointlessly before being set.
11947 *) SIGURG doesn't exist on all platforms.
11948 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
11950 *) When an error occurs during a POST, or other operation with a
11951 request body, the body has to be read from the net before allowing
11952 a keepalive session to continue. [Roy Fielding] PR#1399
11954 *) When an error occurs in fcntl() locking suggest the user look up
11955 the docs for LockFile. [Dean Gaudet]
11957 *) table_set() and table_unset() did not deal correctly with
11958 multiple occurrences of the same key. [Stephen Scheck
11959 <sscheck infonex.net>, Ben Laurie] PR#1604
11961 *) send_fd_length() did not calculate total_bytes_sent properly in error
11962 cases. [Ben Reser <breser regnow.com>] PR#1366
11964 *) r->connection->user was allocated in the wrong pool causing corruption
11965 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
11967 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
11968 Also removed the auto-generated link to www.apache.org that was the
11969 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
11971 *) Multiple "close" tokens may have been set in the "Connection"
11972 header, not an error, but a waste.
11973 [<Ronald.Tschalaer psi.ch>] PR#1683
11975 *) "basic" and "digest" auth tokens should be tested case-insensitive.
11976 [<Ronald.Tschalaer psi.ch>] PR#1599, PR#1666
11978 *) It appears the "257th byte" bug (see
11979 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
11980 at the 256th byte as well. Fixed. [Dean Gaudet]
11982 *) mod_rewrite would not handle %3f properly in some situations.
11985 *) Apache could generate improperly chunked HTTP/1.1 responses when
11986 the bputc() or rputc() functions were used by modules (such as
11987 mod_include). [Dean Gaudet]
11989 *) #ifdef wrap a few #defines in httpd.h to make life easier on
11990 some ports. [Ralf Engelschall]
11992 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
11994 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
11996 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
11998 Changes with Apache 1.2.5
12000 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
12001 only an issue on systems without a MAXDNAME define or where
12002 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
12004 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
12007 *) Fix core dump in the ftp proxy when reading incorrectly formatted
12008 directory listings. [Marc Slemko]
12010 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
12013 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
12014 is used to read various types of files such as htaccess and
12015 htpasswd files. [Marc Slemko]
12017 *) SECURITY: Ensure that the buffer returned by ht_time is always
12018 properly null terminated. [Marc Slemko]
12020 *) SECURITY: General mod_include cleanup, including fixing several
12021 possible buffer overflows and a possible infinite loop. This cleanup
12022 was done against 1.3 code and then backported to 1.2, the result
12023 is a large difference (due to indentation cleanup in 1.3 code).
12024 Users interested in seeing a smaller set of relevant differences
12025 should consider comparing against src/modules/standard/mod_include.c
12026 from the 1.3b3 release. Non-indentation changes to mod_include
12027 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
12029 *) SECURITY: Numerous changes to mod_imap in a general cleanup
12030 including fixing a possible buffer overflow. This cleanup also
12031 was done with 1.3 code as a basis, see the previous note
12032 about mod_include. [Dean Gaudet]
12034 *) SECURITY: If a htaccess file can not be read due to bad
12035 permissions, deny access to the directory with a HTTP_FORBIDDEN.
12036 The previous behavior was to ignore the htaccess file if it could not
12037 be read. This change may make some setups with unreadable
12038 htaccess files stop working. PR#817 [Marc Slemko]
12040 *) SECURITY: no2slash() was O(n^2) in the length of the input.
12041 Make it O(n). This inefficiency could be used to mount a denial
12042 of service attack against the Apache server. Thanks to
12043 Michal Zalewski <lcamtuf boss.staszic.waw.pl> for reporting
12044 this. [Dean Gaudet]
12046 *) mod_include used uninitialized data for some uses of && and ||.
12047 [Brian Slesinsky <bslesins wired.com>] PR#1139
12049 *) mod_imap should decline all non-GET methods.
12050 [Jay Bloodworth <jay pathways.sde.state.sc.us>]
12052 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
12054 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
12055 r->filename. Since those two are meant to be in sync with each other
12056 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
12058 *) mod_include did not properly handle all possible redirects from sub-
12059 requests. [Ken Coar]
12061 *) Inetd mode (which is buggy) uses timeouts without having setup the
12062 jmpbuffer. [Dean Gaudet] PR#1064
12064 *) Work around problem under Linux where a child will start looping
12065 reporting a select error over and over.
12066 [Rick Franchuk <rickf transpect.net>] PR#1107
12068 Changes with Apache 1.2.4
12070 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
12071 always making requests with the full-URI instead of just the URI path.
12072 [Marc Slemko, Roy Fielding]
12074 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
12075 on this platform. [Marc Slemko]
12077 Changes with Apache 1.2.3
12079 *) The request to a remote proxy was mangled if it was generated as the
12080 result of a ProxyPass directive. URL schemes other than http:// were not
12081 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
12082 PR#812 [Lars Eilebrecht]
12084 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
12085 information for case where proxy module is not available. [Marc Slemko]
12087 *) Force proxy to always respond as HTTP/1.0, which it was failing to
12088 do for errors and cached responses. [Roy Fielding]
12090 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
12092 Changes with Apache 1.2.2 [not released]
12094 *) Fixed another long-standing bug in sub_req_lookup_file where it would
12095 happily skip past access checks on subdirectories looked up with relative
12096 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
12099 *) Add lockfile name to error message printed out when
12100 USE_FLOCK_SERIALIZED_ACCEPT is defined.
12103 *) Enhanced the chunking and error handling inside the buffer functions.
12104 [Dean Gaudet, Roy Fielding]
12106 *) When merging the main server's <Directory> and <Location> sections into
12107 a vhost, put the main server's first and the vhost's second. Otherwise
12108 the vhost can't override the main server. [Dean Gaudet] PR#717
12110 *) The <Directory> code would merge and re-merge the same section after
12111 a match was found, possibly causing problems with some modules.
12114 *) Fixed an infinite loop in mod_imap for references above the server root.
12115 [Dean Gaudet] PR#748
12117 *) mod_include cleanup showed that handle_else was being used to handle
12118 endif. It didn't cause problems, but it was cleaned up too.
12121 *) Last official synchronization of mod_rewrite with author version (because
12122 mod_rewrite is now directly developed by the author at the Apache Group):
12123 o added diff between mod_rewrite 3.0.6+ and 3.0.9
12124 minus WIN32/NT stuff, but plus copyright removement.
12126 - workaround for detecting infinite rewriting loops
12127 - fixed setting of env vars when "-" is used as subst string
12128 - fixed forced response code on redirects (PR#777)
12129 - fixed cases where r->args is ""
12130 - kludge to disable locking on pipes under braindead SunOS
12131 - fix for rewritelog in cases where remote hostname is unknown
12132 - fixed totally damaged request_rec walk-back loop
12133 o remove static from local data and add static to global ones.
12134 o replaced ugly proxy finding stuff by simple
12135 find_linked_module("mod_proxy") call.
12136 o added missing negation char on rewritelog()
12137 o fixed a few comment typos
12138 [Ralf S. Engelschall]
12140 *) Anonymous_LogEmail was logging on each subrequest.
12141 [Dean Gaudet] PR#421, PR#868
12143 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
12144 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
12145 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
12146 Additionally mod_browser now triggers during translate_name to workaround
12147 a deficiency in the header_parse phase.

12154 *) Properly treat <files> container like other containers in mod_info.
12155 [Marc Slemko] PR#848
12157 *) The proxy didn't treat the "Host:" keyword of the host header as case-
12158 insensitive. The proxy would corrupt the first line of a response from
12159 an HTTP/0.9 server. [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#813,814
12161 *) mod_include would log some bogus values occasionally.
12162 [Skip Montanaro <skip calendar.com>, Marc Slemko] PR#797
12164 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
12165 under Solaris 2.x (up through 2.5.1). It has been fixed.
12166 [Dean Gaudet] PR#832
12168 *) API: In HTTP/1.1, whether or not a request message contains a body
12169 is independent of the request method and based solely on the presence
12170 of a Content-Length or Transfer-Encoding. Therefore, our default
12171 handlers need to be prepared to read a body even if they don't know
12172 what to do with it; otherwise, the body would be mistaken for the
12173 next request on a persistent connection. discard_request_body()
12174 has been added to take care of that. [Roy Fielding] PR#378
12176 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
12177 release version number, such that it always increases along the
12178 same lines as our source code branching. [Roy Fielding]
12180 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
12182 Changes with Apache 1.2.1
12184 *) SECURITY: Don't serve file system objects unless they are plain files,
12185 symlinks, or directories. This prevents local users from using pipes
12186 or named sockets to invoke programs for an extremely crude form of

12190 could contain "../" allowing a local user to "publish" any file on
12191 the system. No slashes are allowed now. [Dean Gaudet]
12193 *) SECURITY: It was possible to violate the symlink Options using mod_dir
12194 (headers, readmes, titles), mod_negotiation (type maps), or
12195 mod_cern_meta (meta files). [Dean Gaudet]
12197 *) SECURITY: Apache will refuse to run as "User root" unless
12198 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
12200 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
12201 if it contained a .htaccess disallowing symlinks. This is contrary
12202 to the rule that symlink permissions are tested with the symlink
12203 options of the parent directory. [Dean Gaudet] PR#353
12205 *) CONFIG: The LockFile directive can be used to place the serializing
12206 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
12207 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
12210 *) Request processing now retains state of whether or not the request
12211 body has been read, so that internal redirects and subrequests will
12212 not try to read it twice (and block). [Roy Fielding]
12214 *) Add a placeholder in modules/Makefile to avoid errors with certain

12223 *) Attempt to work around problems with third party libraries that do not
12224 handle high numbered descriptors (examples include bind, and
12225 solaris libc). On all systems apache attempts to keep all permanent
12226 descriptors above 15 (called the low slack line). Solaris users
12227 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
12228 which keeps all non-FILE * descriptors above 255. On all systems
12229 this should make supporting large numbers of vhosts with many open
12230 log files more feasible. If this causes trouble please report it,
12231 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
12232 [Dean Gaudet] various PRs
12234 *) Related to the last entry, network sockets are now opened before
12235 log files are opened. The only known case where this can cause
12236 problems is under Solaris with many virtualhosts and many Listen
12237 directives. But using -DHIGH_SLACK_LINE=256 described above will
12238 work around this problem. [Dean Gaudet]

12296 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
12297 apparently due to a mismatch between sigaction and setjmp.
12298 [Roy Fielding] PR#502
12300 *) Log correct status code if we timeout before receiving a request (408)
12301 or if we received a request-line that was too long to process (414).
12302 [Ed Korthof and Roy Fielding] PR#601
12304 *) Virtual hosts with the same ServerName, but on different ports, were
12305 not being selected properly. [Ed Korthof]
12307 *) Added code to return the requested IP address from proxy_host2addr()
12308 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
12309 change submitted by Jozsef Hollosi <hollosi sbcm.com>.
12310 [Chuck Murcko] PR#614
12312 *) If multiple requests on a single connection are used to retrieve
12313 data from different virtual hosts, the virtual host list would be
12314 scanned starting with the most recently used VH instead of the first,
12315 causing most virtual hosts to be ignored.
12316 [Paul Sutton and Martin Mares] PR#610
12318 *) The OS/2 handling of process group was broken by a porting patch for
12319 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
12321 *) Inherit virtual server port from main server if none (or "*") is
12322 given for VirtualHost. [Dean Gaudet] PR#576
12324 *) If the lookup for a DirectoryIndex name with content negotiation
12325 has found matching variants, but none are acceptable, return the
12326 negotiation result if there are no more DirectoryIndex names to lookup.
12327 [Petr Lampa and Roy Fielding]
12329 *) If a soft_timeout occurs after keepalive is set, then the main child
12330 loop would try to read another request even though the connection
12331 has been aborted. [Roy Fielding]
12333 *) Configure changes: Allow for whitespace at the start of a
12334 Module declaration. Also, be more understanding about the
12335 CC=/OPTIM= format in Configuration. Finally, fix compiler
12336 flags if using HP-UX's cc compiler. [Jim Jagielski]
12338 *) Subrequests and internal redirects now inherit the_request from the
12339 original request-line. [Roy Fielding]
12341 *) Test for error conditions before creating output header fields, since
12342 we don't want the error message to include those fields. Likewise,
12343 reset the content_language(s) and content_encoding of the response
12344 before generating or redirecting to an error message, since the new
12345 message will have its own Content-* definitions. [Dean Gaudet]
12347 *) Restored the semantics of headers_out (headers sent only with 200..299
12348 and 304 responses) and err_headers_out (headers sent with all responses).
12349 Avoid the overhead of copying tables if err_headers_out is empty
12350 (the usual case). [Roy Fielding]
12352 *) Fixed a couple places where a check for the default Content-Type was
12353 not properly checking both the value configured by the DefaultType
12354 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
12355 of DEFAULT_TYPE to match the documented default (text/plain).
12356 [Dean Gaudet] PR#506
12358 *) Escape the HTML-sensitive characters in the Request-URI that is
12359 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
12361 *) Properly initialize the flock structures used by the mutex locking
12362 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
12365 *) The method for determining PATH_INFO has been restored to the pre-1.2b
12366 (and NCSA httpd) definition wherein it was the extra path info beyond
12367 the CGI script filename. The environment variable FILEPATH_INFO has
12368 been removed, and instead we supply the original REQUEST_URI to any
12369 script that wants to be Apache-specific and needs the real URI path.
12370 This solves a problem with existing scripts that use extra path info
12371 in the ScriptAlias directive to pass options to the CGI script.
12374 *) The _default_ change in 1.2b10 will change the behaviour on configs
12375 that use multiple Listen statements for listening on multiple ports.
12376 But that change is necessary to make _default_ consistent with other
12377 forms of <VirtualHost>. It requires such configs to be modified
12378 to use <VirtualHost _default_:*>. The documentation has been
12379 updated. [Dean Gaudet] PR#530
12381 *) If an ErrorDocument CGI script is used to respond to an error
12382 generated by another CGI script which has already read the message
12383 body of the request, the server would block trying to read the
12384 message body again. [Rob Hartill]
12386 *) signal() replacement conflicted with a define on QNX (and potentially
12387 other platforms). Fixed. [Ben Laurie] PR#512
12389 Changes with Apache 1.2b10
12391 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
12392 to be configured via -D in Configuration. [Dean Gaudet] PR#449
12394 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
12396 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
12398 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
12399 config, in case the hostent struct returned is trash.
12400 [Chuck Murcko] PR #491
12402 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
12403 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
12405 Changes with Apache 1.2b9 [never announced]
12407 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
12408 changes and in anticipation of 1.2 final release. [Roy Fielding]
12410 *) Fix problem with scripts not receiving a SIGPIPE when client drops
12411 the connection (e.g., when user presses Stop). Apache will now stop
12412 trying to send a message body immediately after an error from write.
12413 [Roy Fielding and Nathan Kurz] PR#335
12415 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
12416 than mod_alias, and mod_alias has higher priority than mod_proxy;
12417 rearranged other modules to enhance understanding of their purpose
12418 and relative order (and maybe even reduce some overhead).
12419 [Roy Fielding and Sameer Parekh]
12421 *) Fix graceful restart. Eliminate many signal-related race
12422 conditions in both forms of restart, and in SIGTERM. See
12423 htdocs/manual/stopping.html for details on stopping and
12424 restarting the parent. [Dean Gaudet]
12426 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
12427 memory allocator to avoid a behaviour that required extra blocks to
12428 be allocated. [Dean Gaudet]
12430 *) Allow suexec to access files relative to current directory but not
12431 above. (Excluding leading / or any .. directory.) [Ken Coar]
12434 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
12435 PR#367, 368, 354, 453
12437 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
12438 while obtaining the /~user and save the username in a separate data
12439 area so that it won't be overwritten by the call to getgrgid(), and
12440 fix some misuse of the pool string allocation functions. Also fixes
12441 a general problem with parsing URL query info into args for CGI scripts.
12442 [Roy Fielding] PR#339, 367, 354, 453
12444 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
12446 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
12448 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
12449 AuthDBAuthoritative. [Marc Slemko] PR#420
12451 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
12453 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
12454 object that can't be PUT, or FOOBAR for some method FOOBAR that
12455 apache doesn't know about at all). Log 404s that occur in mod_include.
12456 [Paul Sutton, John Van Essen]
12458 *) If a soft timeout (or lingerout) occurs while trying to flush a
12459 buffer or write inside buff.c or fread'ing from a CGI's output,
12460 then the timeout would be ignored. [Roy Fielding] PR#373
12462 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
12463 parsing of headers. If the terminating empty-line CRLF occurs starting
12464 at the 256th or 257th byte of output, then Navigator will think a normal
12465 image is invalid. We are guessing that this is because their initial
12466 read of a new request uses a 256 byte buffer. We check the bytes written
12467 so far and, if we are about to tickle the bug, we instead insert a
12468 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
12470 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
12471 of an external redirection. [Roy Fielding and Paul Sutton]
12473 *) Configure would create a broken Makefile if the configuration file
12474 contained a commented-out Rule. [Roy Fielding]
12476 *) Promote per_dir_config and subprocess_env from the subrequest to the
12477 main request in mod_negotiation. In particular this fixes a bug
12478 where <Files> sections wouldn't properly apply to negotiated content.
12481 *) Fix a potential deadlock in mod_cgi script_err handling.
12482 [Ralf S. Engelschall]
12484 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
12485 [Mitchell Blank Jr]
12487 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
12488 .htaccess files because the RewriteBase was not replaced correctly.
12489 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
12490 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
12492 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
12493 1.x the settings are those of pre-1.2b8. For 2.x we include
12494 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
12495 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
12496 [Dean Gaudet] PR#336, PR#340
12498 *) Redirect did not preserve ?query_strings when present in the client's
12499 request. [Dean Gaudet]
12501 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
12503 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
12505 *) Add UnixWare compile/install instructions. [Chuck Murcko]
12507 *) Add mod_example (illustration of API techniques). [Ken Coar]
12509 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
12511 *) Improve handling of directories when filenames have spaces in them.
12514 *) For hosts with multiple IP addresses, try all additional addresses if
12515 necessary to get a connect. Fail only if hostent address list is
12516 exhausted. [Chuck Murcko]
12518 *) More signed/unsigned port fixes. [Dean Gaudet]
12520 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
12523 Changes with Apache 1.2b8
12525 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
12526 to it. [Marc Slemko]
12528 *) The addition of <Location> and <File> directives made the
12529 sub_req_lookup_simple() function bogus, so we now handle
12530 the special cases directly. [Dean Gaudet]
12532 *) We now try to log where the server is dumping core when a fatal
12533 signal is received. [Ken Coar]
12535 *) Improved lingering_close by adding a special timeout, removing the
12536 spurious log messages, removing the nonblocking settings (they
12537 are not needed with the better timeout), and adding commentary
12538 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
12539 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
12541 *) Send error messages about setsockopt failures to the server error
12542 log instead of stderr. [Roy Fielding]
12544 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
12546 *) Stopgap solution for CGI 3-second delay with server-side includes: if
12547 processing a subrequest, allocate memory from r->main->pool instead
12548 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
12549 in the middle of an SSI request. [Dean Gaudet] PR #122
12551 *) Fixed status of response when POST is received for a nonexistent URL
12552 (was sending 405, now 404) and when any method is sent with a
12553 full-URI that doesn't match the server and the server is not acting
12554 as a proxy (was sending 501, now 403). [Roy Fielding]
12556 *) Host port changed to unsigned short. [Ken Coar] PR #276
12558 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
12560 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
12562 *) Report extra info from errno with many errors that cause httpd to exit.
12563 spawn_child, popenf, and pclosef now have valid errno returns in the
12564 event of an error. Correct problems where errno was stomped on
12565 before being reported. [Dean Gaudet]
12567 *) In the proxy, if the cache filesystem was full, garbage_coll() was
12568 never called, and thus the filesystem would remain full indefinitely.
12569 We now also remove incomplete cache files left if the origin server
12570 didn't send a Content-Length header and either the client has aborted
12571 transfer or bwrite() to client has failed. [Petr Lampa]
12573 *) Fixed the handling of module and script-added header fields.
12574 Improved the interface for sending header fields and reduced
12575 the duplication of code between sending okay responses and errors.
12576 We now always send both headers_out and err_headers_out, and
12577 ensure that the server-reserved fields are not being overridden,
12578 while not overriding those that are not reserved. [Roy Fielding]
12580 *) Moved transparent content negotiation fields to err_headers_out
12581 to reflect above changes. [Petr Lampa]
12583 *) Fixed the determination of whether or not we should make the
12584 connection persistent for all of the cases where some other part
12585 of the server has already indicated that we should not. Also
12586 improved the ordering of the test so that chunked encoding will
12587 be set whenever it is desired instead of only when KeepAlive
12588 is enabled. Added persistent connection capability for most error
12589 responses (those that do not indicate a bad input stream) when
12590 accessed by an HTTP/1.1 client. [Roy Fielding]
12592 *) Added missing timeouts for sending header fields, error responses,
12593 and the last chunk of chunked encoding, each of which could have
12594 resulted in a process being stuck in write forever. Using soft_timeout
12595 requires that the sender check for an aborted connection rather than
12596 continuing after an EINTR. Timeouts that used to be initiated before
12597 send_http_header (and never killed) are now initiated only within or
12598 around the routines that actually do the sending, and not allowed to
12599 propagate above the caller. [Roy Fielding]
12601 *) mod_auth_anon required an @ or a . in the email address, not both.
12604 *) per_dir_defaults weren't set correctly until directory_walk for
12605 name-based vhosts. This fixes an obscure bug with the wrong config
12606 info being used for vhosts that share the same ip as the server.
12609 *) Improved generation of modules/Makefile to be more generic for
12610 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
12612 *) Generate makefile dependency for Configuration based on the actual
12613 name given when running the Configure process. [Dean Gaudet]
12615 *) Fixed problem with vhost error log not being set prior to
12616 initializing virtual hosts. [Dean Gaudet]
12618 *) Fixed infinite loop when a trailing slash is included after a type map
12619 file URL (extra path info). [Petr Lampa]
12621 *) Fixed server status updating of per-connection counters. [Roy Fielding]
12623 *) Add documentation for DNS issues (reliability and security), and try
12624 to explain the virtual host matching process. [Dean Gaudet]
12626 *) Try to continue gracefully by disabling the vhost if a DNS lookup
12627 fails while parsing the configuration file. [Dean Gaudet]
12629 *) Improved calls to setsockopt. [Roy Fielding]
12631 *) Negotiation changes: Don't output empty content-type in variant list;
12632 Output charset in variant list; Return sooner from handle_multi() if
12633 no variants found; Add handling of '*' wildcard in Accept-Charset.
12634 [Petr Lampa and Paul Sutton]
12636 *) Fixed overlaying of request/sub-request notes and headers in
12637 mod_negotiation. [Dean Gaudet]
12639 *) If two variants' charset quality are equal and one is the default
12640 charset (iso-8859-1), then prefer the variant that was specifically
12641 listed in Accept-Charset instead of the default. [Petr Lampa]
12643 *) Memory allocation problem in push_array() -- it would corrupt memory
12644 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
12646 *) invoke_handler() doesn't handle mime arguments in content-type
12647 [Petr Lampa] PR#160
12649 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
12652 *) Fixed problem with ErrorDocument not working for virtual hosts
12653 due to one of the performance changes in 1.2b7. [Dean Gaudet]
12655 *) Log an error message if we get a request header that is too long,
12656 since it may indicate a buffer overflow attack. [Marc Slemko]
12658 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
12659 not reject URLs without a double-slash, as per RFC2068 section 3.2.
12660 [Ken Coar] PR #146, #187
12662 *) Added table entry placeholder for new header_parser callback
12663 in all of the distributed modules. [Ken Coar] PR #191
12665 *) Allow for cgi files without the .EXE extension on them under OS/2.
12666 [Garey Smiley] PR #59
12668 *) Fixed error message when resource is not found and URL contains
12669 path info. [Petr Lampa and Dean Gaudet] PR #40
12671 *) Fixed user and server confusion over what should be a virtual host
12672 and what is the main server, resulting in access to something
12673 other than the name defined in the virtualhost directive (but
12674 with the same IP address) failing. [Dean Gaudet]
12676 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
12677 AIX; improves the redirection stuff to enable the users to generally
12678 redirect to http, https, gopher and ftp; added TIME variable for
12679 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
12680 special patterns >STRING, <STRING and =STRING to RewriteCond, which
12681 can be used in conjunction with %{TIME} or other variables to create
12682 time-dependent rewriting rules. [Ralf S. Engelschall]
12684 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
12685 Module authors may need to adjust their code for proper cleanup to take
12686 place (that is, call note_cleanups_for_fd()). This change fixes problems
12687 with file descriptors being erroneously closed when the proxy module was
12688 in use. [Ben Laurie]
12690 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
12691 initgroups() to hose the group information needed for later
12692 comparisons. [Randy Terbush]
12694 *) Remove unnecessary call to va_end() in create_argv() which
12695 caused a SEGV on some systems.
12697 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
12700 *) Clear memory allocated for listeners. [Randy Terbush]
12702 *) Improved handling of IP address as a virtualhost address and
12703 introduced "_default_" as a synonym for the default vhost config.

12713 - replace protocol response numbers with symbols
12714 - save variant-list into main request notes
12715 - free allocated memory from subrequests
12716 - merge notes, headers_out and err_headers_out
12718 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
12719 "HTTP/#.# ###*" to be more lenient about what we accept.
12722 *) more proxy FTP bug fixes:
12723 - Changed send_dir() to remove user/passwd from displayed URL.
12724 - Changed login error messages to be more descriptive.
12725 - remove setting of SO_DEBUG socket option
12726 - Make ftp_getrc() more lenient about multiline responses,
12727 specifically, 230 responses which don't have continuation 230-
12728 on each line). These seem to be all NT FTP servers, and while
12729 perhaps questionable, they appear to be legal by RFC 959.
12730 - Add missing kill_timeout() after transfer to user completes.
12733 *) Fixed problem where a busy server could hang when restarting
12734 after being sent a SIGHUP due to child processes not exiting.
12737 *) Modify mod_include escaping so a '\' only signifies an escaped
12738 character if the next character is one that needs
12739 escaping. [Ben Laurie]
12741 *) Eliminated possible infinite loop in mod_imap when relative URLs are
12742 used with a 'base' directive that does not have a '/' in it.
12743 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
12745 *) Reduced the default timeout from 1200 seconds to 300, and the
12746 one in the sample configfile from 400 to 300. [Marc Slemko]
12748 *) Stop vbprintf from crashing if given a NULL string pointer;
12749 print (null) instead. [Ken Coar]
12751 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
12752 [Marc Slemko and Roy Fielding]
12754 *) Fixed problem with mod_cgi-generated internal redirects trying to
12755 read the request message-body twice. [Archie Cobbs and Roy Fielding]
12757 *) Reduced timeout on lingering close, removed possibility of a blocked
12758 read causing the child to hang, and stopped logging of errors if
12759 the socket is not connected (reset by client). [Roy Fielding]
12761 *) Rearranged main child loop to remove duplication of code in
12762 select/accept and keep-alive requests, fixed several bugs regarding
12763 checking scoreboard_image for exit indication and failure to
12764 account for all success conditions and trap all error conditions,
12765 prevented multiple flushes before closing the socket; close the entire
12766 socket buffer instead of just one descriptor, prevent logging of
12767 EPROTO and ECONNABORTED on platforms where supported, and generally
12768 improved readability. [Roy Fielding]
12770 *) Extensive performance improvements. Cleaned up inefficient use of
12771 auto initializers, multiple is_matchexp calls on a static string,
12772 and excessive merging of response_code_strings. [Dean Gaudet]
12774 *) Added double-buffering to mod_include to improve performance on
12775 server-side includes. [Marc Slemko]
12777 *) Several fixes for suexec wrapper. [Randy Terbush]
12778 - Make wrapper work for files on NFS filesystem.
12779 - Fix portability problem of MAXPATHLEN.
12780 - Fix array overrun problem in clean_env().
12781 - Fix allocation of PATH environment variable
12783 *) Removed extraneous blank line is description of mod_status chars.
12786 *) Logging of errors from the call_exec routine simply went nowhere,
12787 since the logfile fd has been closed, so now we send them to stderr.
12788 [Harald T. Alvestrand]
12790 *) Fixed core dump when DocumentRoot is a CGI.
12791 [Ben Laurie, reported by <geddis tesserae.com>]
12793 *) Fixed potential file descriptor leak in mod_asis; updated it and
12794 http_core to use pfopen/pfclose instead of fopen/fclose.
12795 [Randy Terbush and Roy Fielding]
12797 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
12798 as the DEC Alpha which is 64-bit but uses 32-bit ints.

12801 *) Return a 302 response code to the client when sending a redirect
12802 due to a missing trailing '/' on a directory instead of a 301; now
12803 it is cacheable. [Markus Gyger]
12805 *) Fix condition where, if a bad directive occurs in .htaccess, and
12806 sub_request() goes first to this directory, then log_reason() will
12807 SIGSEGV because it doesn't have initialized r->per_dir_config.
12808 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
12810 *) Fix handling of lang_index in is_variant_better(). This was
12811 causing problems which resulted in the server sending the
12812 wrong language document in some cases. [Petr Lampa]
12814 *) Remove free() from clean_env() in suexec wrapper. This was nuking
12815 the clean environment on some systems.
12817 *) Tweak byteserving code (e.g. serving PDF files) to work around
12818 bugs in Netscape Navigator and Microsoft Internet Explorer.
12819 Emit Content-Length header when sending multipart/byteranges.
12822 *) Port to HI-UX/WE2. [Nick Maclaren]
12824 *) Port to HP MPE operating system for HP 3000 machines
12825 [Mark Bixby <markb cccd.edu>]
12827 *) Fixed bug which caused a segmentation fault if only one argument
12828 given to RLimit* directives. [Ed Korthof]
12830 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
12832 *) Improved buffered output to the client by delaying the flush decision
12833 until the BUFF code is actually about to read the next request.
12834 This fixes a problem introduced in 1.2b5 with clients that send
12835 an extra CRLF after a POST request. Also improved chunked output
12836 performance by combining writes using writev() and removing as
12837 many bflush() calls as possible. NOTE: Platforms without writev()
12838 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
12839 or Configure, unless we have already done so. [Dean Gaudet]
12841 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
12843 *) Fixed mod_info output corruption bug introduced by buffer overflow
12844 fixes. [Dean Gaudet]
12846 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
12847 for the special case of a 304 response. [Paul Sutton]
12849 *) Improved handling of TRACE method by bypassing normal method handling
12850 and header parsing routines; fixed Allow response to always allow TRACE.
12853 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
12855 *) Cleaned-up some of the generated HTML. [Ken Coar]
12857 Changes with Apache 1.2b6
12859 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
12861 *) Fix typo introduced in fix for potential infinite loop around
12862 accept() in child_main(). This change caused the rev to 1.2b6.
12863 1.2b5 was never a public beta.
12865 Changes with Apache 1.2b5
12867 *) Change KeepAlive semantics (On|Off instead of a number), add
12868 MaxKeepAliveRequests directive. [Alexei Kosut]
12870 *) Various NeXT compilation patches, as well as a change in
12871 regex/regcomp.c since that file also used a NEXT define.
12874 *) Allow * to terminate the end of a directory match in mod_dir.
12875 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
12877 *) Don't call can_exec() if suexec_enabled. Calling this requires
12878 scripts executed by the suexec wrapper to be world executable, which
12879 defeats one of the advantages of running the wrapper. [Randy Terbush]
12881 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
12884 *) Migration from sprintf() to snprintf() to avoid buffer
12885 overflows. [Marc Slemko]
12887 *) Provide portable snprintf() implementation (ap_snprintf)
12888 as well as *cvt family. [Jim Jagielski]
12890 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
12893 *) Remove mod_fastcgi.c from the distribution. This module appears
12894 to be maintained more through the Open Market channels and should
12895 continue to be easily available at http://www.fastcgi.com/
12897 *) Fixed bug in modules/Makefile that wouldn't allow building in more
12898 than one subdirectory (or cleaning, either). [Jeremy Laidman]
12900 *) mod_info assumed that the config files were relative to ServerRoot.
12903 *) CGI scripts called as an error document resulting from failed
12904 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
12906 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
12909 *) Properly check errno to prevent display of a directory index
12910 when server receives a long enough URL to confuse stat().
12913 *) Several security enhancements to suexec wrapper. It is _highly_
12914 recommended that previously installed versions of the wrapper
12915 be replaced with this version. [Randy Terbush, Jason Dour]
12917 - ~user execution now properly restricted to ~user's home
12918 directory and below.
12919 - execution restricted to UID/GID > 100
12920 - restrict passed environment to known variables
12921 - call setgid() before initgroups() (portability fix)
12922 - remove use of setenv() (portability fix)
12924 *) Add HTTP/1.0 response forcing. [Ben Laurie]
12926 *) Add access control via environment variables. [Ben Laurie]
12928 *) Add rflush() function. [Alexei Kosut]
12930 *) remove duplicate pcalloc() call in new_connection().
12932 *) Fix incorrect comparison which could allow number of children =
12933 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
12934 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
12936 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
12937 AIX PS/2, CONVEXOS. [Jim Jagielski]
12939 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
12940 It's more portable. [Martin Kraemer]
12942 *) Replace references to make in Makefile.tmpl with $(MAKE).
12945 *) Add ProxyBlock directive w/IP address caching. Add IP address
12946 caching to NoCache directive as well. ProxyBlock works with all
12947 handlers; NoCache now also works with FTP for anonymous logins.
12948 Still more code cleanup. [Chuck Murcko]
12950 *) Add "header parse" API hook [Ben Laurie]
12952 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
12954 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
12956 *) Correctly allow access and auth directives in <Files> sections in
12957 server config files. [Alexei Kosut]
12959 *) Fix bug with ServerPath that could cause certain files to be not
12960 found by the server. [Alexei Kosut]
12962 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
12963 double-quote from text and so that it properly checks for unsupported
12964 status codes using the new index_of_response interface. [Roy Fielding]
12966 *) Multiple fixes to the lingering_close code in order to avoid being
12967 interrupted by a stray timeout, to avoid lingering on a connection
12968 that has already been aborted or never really existed, to ensure that
12969 we stop lingering as soon as any error condition is received, and to
12970 prevent being stuck indefinitely if the read blocks. Also improves
12971 reporting of error conditions. [Marc Slemko and Roy Fielding]
12973 *) Fixed initialization of parameter structure for sigaction.
12974 [<mgyger itr.ch>, Adrian Filipi-Martin]
12976 *) Fixed reinitializing the parameters before each call to accept and
12977 select, and removed potential for infinite loop in accept.
12978 [Roy Fielding, after useful PR from <adrian virginia.edu>]
12980 *) Fixed condition where, if a child fails to fork, the scoreboard would
12981 continue to say SERVER_STARTING forever. Eventually, the main process
12982 would refuse to start new children because count_idle_servers() will
12983 count those SERVER_STARTING entries and will always report that there
12984 are enough idle servers. [Phillip Vandry]
12986 *) Fixed bug in bcwrite regarding failure to account for partial writes.
12987 Avoided calling bflush() when the client is pipelining requests.
12988 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
12990 *) Added description of "." mode in server-status [Jim Jagielski]
12992 Changes with Apache 1.2b4
12994 *) Fix possible race condition in accept_mutex_init() that
12995 could leave a small security hole open allowing files to be
12996 overwritten in cases where the server UID has write permissions.
12999 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
13001 *) Fix portablity problem in util_script where ARG_MAX may not be
13002 defined for some systems.
13004 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
13007 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
13008 style magic #! token for better script portability. [Garey Smiley]
13010 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
13011 execution for ~userdir CGI. [Jason Dour]
13013 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
13015 *) Fix month off by one in suexec wrapper logging.
13017 Changes with Apache 1.2b3:
13019 *) Fix error in mod_cgi which could cause resources not to be properly
13020 freed, or worse. [Dean Gaudet]
13022 *) Fix find_string() NULL pointer dereference. [Howard Fear]
13024 *) Add set_flag_slot() at the request of Dirk and others.
13027 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
13029 *) Add changes to improve the error message given for invalid
13030 ServerName parameters. [Dirk vanGulik]
13032 *) Add "Authoritative" directive for Auth modules that don't
13033 currently have it. This gives admin control to assign authoritative
13034 control to an authentication scheme and allow "fall through" for
13035 those authentication modules that aren't "Authoritative" thereby
13036 allowing multiple authentication mechanisms to be chained.
13039 *) Remove requirement for ResourceConfig/AccessConfig if not using
13040 the three config file layout. [Randy Terbush]
13042 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
13044 *) Changes to suexec wrapper to fix the following problems:
13045 1. symlinked homedirs will kill ~userdirs.
13046 2. initgroups() on Linux 2.0.x clobbers gr->grid.
13047 3. CGI command lines paramters problems
13048 4. pw-pwdir for "docroot check" still the httpd user's pw record.
13049 [Randy Terbush, Jason Dour]
13051 *) Change create_argv() to accept variable arguments. This fixes
13052 a problem where arguments were not getting passed to the CGI via
13053 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
13055 *) Collapse multiple slashes in path URLs to properly apply
13056 handlers defined by <Location>. [Alexei Kosut]
13058 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
13060 *) Improve the accuracy of request duration timings by setting
13061 r->request_time in read_request_line() instead of read_request().
13064 *) Reset timeout while reading via get_client_block() in mod_cgi.c
13065 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
13067 *) Add the ability to pass different Makefile.tmpl files to Configure
13068 using the -make flag. [Rob Hartill]
13070 *) Fix coredump triggered when sending a SIGHUP to the server caused
13071 by an assertion failure, in turn caused by an uninitialised field in a
13075 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
13076 PATH_INFO from previous versions of Apache (in certain situations,
13077 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
13078 [later removed in 1.2b11]
13080 *) Add rwrite() function to API to allow for sending strings of
13081 arbitrary length. [Doug MacEachern]
13083 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
13085 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
13086 NeXT. [Jim Jagielski]
13088 *) Removed recent modification to promote the status code on internal
13089 redirects, since the correct fix was to change the default log format
13090 in mod_log_config so that it outputs the original status. [Rob Hartill]
13092 Changes with Apache 1.2b2:
13094 *) Update set_signals() to use sigaction() for setting handlers.
13095 This appears to fix a re-entrant problem in the seg_fault()
13096 bus_error() handlers. [Randy Terbush]
13098 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
13100 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
13102 *) proxy_http.c bugfixes: [Chuck Murcko]
13103 1) fixes possible NULL pointer reference w/NoCache
13104 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
13105 host would cache nothing if it was in the local domain,
13106 and the local domain was in the NoCache list)
13107 3) Adds Host: header when not available
13108 4) Some code cleanup and clarification
13110 *) mod_include.c bugfixes:
13111 1) Fixed an ommission that caused include variables to not
13112 be parsed in config errmsg directives [Howard Fear]
13113 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
13114 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
13115 4) Allow backslash-escaping to all quoted text
13116 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
13117 5) Pass variable to command line if not set in XSSI's env
13120 *) Fix infinite loop when processing Content-language lines in
13121 type-map files. [Alexei Kosut]
13123 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
13125 *) Fixed problem in set_[user|group] that prevented CGI execution
13126 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
13128 *) Added PORTING information file. [Jim Jagielski]
13130 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
13132 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
13134 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
13135 USE_FCNTL_SERIALIZED_ACCEPT was intended.
13137 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
13138 which caused problems of systems where socket s_addr is >32bits.
13140 *) Added comment to explain (r->chunked = 1) side-effect in
13141 http_protocol.c [Roy Fielding]
13143 *) Replaced use of index() in mod_expires.c with more appropriate
13144 and portable isdigit() test. [Ben Laurie]
13146 *) Updated Configure for ...
13147 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
13148 *-dg-dgux* (bad pattern match)
13149 QNX (DEF_WANTHSREGEX=yes)
13150 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
13152 *-unixware211 (new)
13153 and added some user diagnostic info. [Ben Laurie]
13155 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
13156 for better portability. [Jim Jagielski]
13158 *) Updated helpers/GuessOS for ...
13159 SCO 5 (recognize minor releases)
13160 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
13161 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
13162 IRIX64 (-sgi-irix64)
13163 ULTRIX (-unknown-ultrix)
13164 SINIX (-whatever-sysv4)
13165 NCR Unix (-ncr-sysv4)
13166 and fixed something in helpers/PrintPath [Ben Laurie]
13168 Changes with Apache 1.2b1
13170 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
13172 Changes with Apache 1.1.1
13174 *) Fixed bug where Cookie module would make two entries in the
13175 logfile for each access [Mark Cox]
13177 *) Fixed bug where Redirect in .htaccess files would cause memory
13178 leak. [Nathan Neulinger]
13180 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
13182 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
13184 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
13186 Changes with Apache 1.1.0
13188 *) Bring NeXT support up to date. [Takaaki Matsumoto]
13190 *) Bring QNX support up to date. [Ben Laurie]
13192 *) Make virtual hosts default to main server keepalive parameters.
13193 [Alexei Kosut, Ben Laurie]
13195 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
13197 *) Fix missing address family for connect, also remove unreachable statement
13198 in mod_proxy. [Ben Laurie]
13200 *) mod_env now turned on by default in Configuration.tmpl.
13202 *) Bugs which were fixed:
13203 a) yet more mod_proxy bugs [Ben Laurie]
13204 b) CGI works again with inetd [Alexei Kosut]
13205 c) Leading colons were stripped from passwords [<osm interguide.com>]
13206 d) Another fix to multi-method Limit problem [<jk tools.de>]
13208 Changes with Apache 1.1b4
13210 *) r->bytes_sent variable restored. [Robert Thau]
13212 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
13214 *) More possibly unsecure programs removed from the support directory.
13216 *) More mod_auth_msql authentication improvements.
13218 *) VirtualHosts based on Host: headers no longer conflict with the
13221 *) OS/2 compatibility enhancements. [Gary Smiley]
13223 *) POST now allowed to directory index CGI scripts.
13225 *) Actions now work with files of the default type.
13227 *) Bugs which were fixed:
13228 a) more mod_proxy bugs
13229 b) early termination of inetd requests
13230 c) compile warnings on several systems
13231 d) problems when scripts stop reading output early
13233 Changes with Apache 1.1b3
13235 *) Much of cgi-bin and all of cgi-src has been removed, due to
13236 various security holes found and that we could no longer support
13239 *) The "Set-Cookie" header is now special-cased to not merge multiple
13240 instances, since certain popular browsers can not handle multiple
13241 Set-Cookie instructions in a single header. [Paul Sutton]
13243 *) rprintf() added to buffer code, occurrences of sprintf removed.
13246 *) CONNECT method for proxy module, which means tunneling SSL should work.
13247 (No crypto needed) Also a NoCache config directive.
13249 *) Several API additions: pstrndup(), table_unset() and get_token()
13250 functions now available to modules.
13252 *) mod_imap fixups, in particular Location: headers are now complete
13255 *) New "info" module which reports on installed module set through a
13256 special URL, a la mod_status.
13258 *) "ServerPath" directive added - allows for graceful transition
13259 for Host:-header-based virtual hosts.
13261 *) Anonymous authentication module improvements.
13263 *) MSQL authentication module improvements.
13265 *) Status module design improved - output now table-based. [Ben Laurie]
13267 *) htdigest utility included for use with digest authentication
13270 *) mod_negotiation: Accept values with wildcards to be treated with
13271 less priority than those without wildcards at the same quality
13272 value. [Alexei Kosut]
13274 *) Bugs which were fixed:
13275 a) numerous mod_proxy bugs
13276 b) CGI early-termination bug [Ben Laurie]
13277 c) Keepalives not working with virtual hosts
13278 d) RefererIgnore problems
13279 e) closing fd's twice in mod_include (causing core dumps on
13280 Linux and elsewhere).
13282 Changes with Apache 1.1b2
13285 a) core dumps in mod_digest
13286 b) truncated hostnames/ip address in the logs
13287 c) relative URL's in mod_imap map files
13289 Changes with Apache 1.1b1
13291 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
13293 Changes with Apache 1.0.3
13295 *) Internal redirects which occur in mod_dir.c now preserve the
13296 query portion of a request (the bit after the question mark).
13299 *) Escape active characters '<', '>' and '&' in html output in
13300 directory listings, error messages and redirection links.
13303 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
13305 *) Fix for POSIX compliance in waiting for processes in alloc.c.
13308 *) setsockopt no longer takes a const declared argument [Martijn Koster]
13310 *) Reset timeout timer after each successful fwrite() to the network.
13311 This patch adds a reset_timeout() procedure that is called by
13312 send_fd() to reset the timeout ever time data is written to the net.
13315 *) timeout() signal handler now checks for SIGPIPE and reports
13316 lost connections in a more user friendly way. [Rob Hartill]
13318 *) Location of the "scoreboard" file which used to live in /tmp is
13319 now configurable (for OSes that can't use mmap) via ScoreBoardFile
13320 which works similar to PidFile (in httpd.conf) [Rob Hartill]
13322 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
13324 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
13325 which caused a SEGV with cookies enabled
13327 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
13330 *) Log the UNIX textual error returned by some system calls, in
13331 particular errors from accept() [David Robinson]
13333 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
13335 Changes with Apache 1.0.2
13337 *) patch to get Apache compiled on UnixWare 2.x, recommended as
13338 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
13340 *) Fix get_basic_auth_pw() to set the auth_type of the request.
13343 *) past changes to http_config.c to only use the
13344 setrlimit function on systems defining RLIMIT_NOFILE
13345 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
13346 for SUNOS and prototypes the needed functions.
13348 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
13351 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
13353 *) Merge multiple headers from CGI scripts instead of taking last
13354 one. [David Robinson]
13356 *) Add support for SCO 5. [Ben Laurie]
13358 Changes with Apache 1.0.1
13360 *) Silence mod_log_referer and mod_log_agent if not configured
13363 *) Recursive includes can occur if the client supplies PATH_INFO data
13364 and the server provider uses relative links; as file.html
13365 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
13367 *) The replacement for initgroups() did not call {set,end}grent(). This
13368 had two implications: if anything else used getgrent(), then
13369 initgroups() would fail, and it was consuming a file descriptor.
13372 *) On heavily loaded servers it was possible for the scoreboard to get
13373 out of sync with reality, as a result of a race condition.
13374 The observed symptoms are far more Apaches running than should
13375 be, and heavy system loads, generally followed by catastrophic
13376 system failure. [Ben Laurie]
13378 *) Fix typo in license. [David Robinson]
13380 Changes with Apache 1.0.0 23 Nov 1995
13382 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
13384 Changes with Apache 0.8.16 05 Nov 1995
13386 *) New man page for 'httpd' added to support directory [David Robinson]
13388 *) .htgroup files can have more than one line giving members for a
13389 given group (each must have the group name in front), for NCSA
13390 back-compatibility [Robert Thau]
13392 *) Mutual exclusion around accept() is on by default for SVR4 systems
13393 generally, since they generally can't handle multiple processes in
13394 accept() on the same socket. This should cure flaky behavior on
13395 a lot of those systems. [David Robinson]
13397 *) AddType, AddEncoding, and AddLanguage directives take multiple
13398 extensions on a single command line [David Robinson]
13400 *) UserDir can be disabled for a given virtual host by saying
13401 "UserDir disabled" in the <VirtualHost> section --- it was a bug
13402 that this didn't work. [David Robinson]
13404 *) Compiles on QNX [Ben Laurie]
13406 *) Corrected parsing of ctime time format [David Robinson]
13408 *) httpd does a perror() before exiting if it can't log its pid
13409 to the PidFile, to make diagnosing the error a bit easier.
13412 *) <!--#include file="..."--> can no longer include files in the
13413 parent directory, for NCSA back-compatibility. [David Robinson]
13415 *) '~' is *not* escaped in URIs generated for directory listings
13418 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
13420 *) Fixed bug involving handling URIs with escaped %-characters
13421 in redirects [David Robinson]
13423 Changes with Apache 0.8.15 14 Oct 1995
13425 *) Switched to new, simpler license
13427 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
13429 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
13431 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
13433 *) Correctly handles internal redirects to files with names containing '%'
13436 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
13438 *) Use geteuid() rather than getuid() to see if we have root privilege,
13439 so that server correctly resets privilege if run setuid root. [Andrew
13442 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
13445 *) Fix relative URLs in imagemap files [Randy Terbush]
13447 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
13450 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
13451 entries all name the same one. [David Robinson]
13453 *) Fix directory listings with filenames containing unusual characters
13456 *) Better URI-escaping for generated URIs in directories with filenames
13457 containing unusual characters [Ben Laurie]
13459 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
13461 *) Unblock alarms on error return from spawn_child() [David Robinson]
13463 *) Sample Config files have extra note for SCO users [Ben Laurie]
13465 *) Configuration has note for HP-UX users [Rob Hartill]
13467 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
13469 *) Nuked bogus #define in httpd.h [David Robinson]
13471 *) Better test for whether a system has setrlimit() [David Robinson]
13473 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
13475 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
13478 Changes with Apache 0.8.14 19 Sep 1995
13480 *) Compiles on SCO ODT 3.0 [Ben Laurie]
13482 *) AddDescription works (better) [Ben Laurie]
13484 *) Leaves an intelligible error diagnostic when it can't set group
13485 privileges on standalone startup [Andrew Wilson]
13487 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
13488 that machine, which claims to be BSD but does not support RLIMIT.
13491 *) gcc -Wall no longer complains about an unused variable when util.c
13492 is compiled with -DMINIMAL_DNS [Andrew Wilson]
13494 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
13496 Changes with Apache 0.8.13 07 Sep 1995
13498 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
13500 *) Have built-in imagemap code recognize & honor Point directive [James
13503 *) Generate cleaner directory listings in directories with a mix of
13504 long and short filenames [Rob Hartill]
13506 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
13508 *) Properly default ServerName for virtual servers [Robert Thau]
13510 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
13511 Paul Richards and a cast of thousands...]
13513 *) On self-identified BSD systems (we don't try to guess any more),
13514 allocate a few extra file descriptors per virtual host with setrlimit,
13515 if we can, to avoid running out. [Randy Terbush]
13517 *) Write 22-character lock file name into buffer with enough space
13518 on startup [Konstantin Olchanski]
13520 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
13523 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
13525 *) Suppress -Wall warning by initializing variable in negotiation code
13526 [Tobias Weingartner]
13528 Changes with Apache 0.8.12 31 Aug 1995
13530 *) Doesn't pause three seconds after including a CGI script which is
13531 too slow to die off (this is done by not even trying to kill off
13532 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
13533 after the entire document has been processed). [Robert Thau]
13535 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
13537 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
13539 *) Allows .htaccess files to override <Directory> sections naming the
13540 same directory [David Robinson]
13542 *) Removed an efficiency hack in sub_req_lookup_uri which was
13543 causing certain extremely marginal cases (e.g., ScriptAlias of a
13544 *particular* index.html file) to fail. [David Robinson]
13546 *) Doesn't log an error when the requested URI requires
13547 authentication, but no auth header line was supplied by the
13548 client; this is a normal condition (the client doesn't no auth is
13549 needed here yet). [Robert Thau]
13551 *) Behaves more sanely when the name server loses its mind [Sean Welch]
13553 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
13555 *) RFC931 code no longer passes out name of prior clients on current
13556 requests if the current request came from a server that doesn't
13557 do RFC931. [David Robinson]
13559 *) Configuration script accepts "Module" lines with trailing whitespace.
13562 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
13564 *) Cleaned up comments in mod_cgi.c [Robert Thau]
13566 Changes with Apache 0.8.11 24 Aug 1995
13568 *) Wildcard <Directory> specifications work. [Robert Thau]
13570 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
13572 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
13573 the file being requested itself, in addition to the directories leading
13574 up to it. [Robert Thau]
13576 *) Logs access failures due to symlink checks or invalid client address
13577 in the error log [Roy Fielding, Robert Thau]
13579 *) Symlink checks deal correctly with systems where lstat of
13580 "/path/to/some/link/" follows the link. [Thau, Fielding]
13582 *) Doesn't reset DirectoryIndex to 'index.html' when
13583 other directory options are set in a .htaccess file. [Robert Thau]
13585 *) Clarified init code and nuked bogus warning in mod_access.c
13586 [Florent Guillaume]
13588 *) Corrected several directives in sample srm.conf
13589 --- includes corrections to directory indexing icon-related directives
13590 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
13591 icons for encodings right, and turning on AddEncoding by default).
13594 *) Corrected descriptions of args to AddIcon and AddAlt in command table
13597 *) INSTALL & README mention "contributed modules" directory [Brian
13600 *) Fixed English in the license language... "for for" --> "for".
13603 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
13604 mod_alias.c, merging it almost completely with handling of Alias, and
13605 adding a 'notes' field to the request_rec which allows the CGI module
13606 to discover whether the Alias module has put this request through
13607 ScriptAlias (which it needs to know for back-compatibility, as the old
13608 NCSA code did not check Options ExecCGI in ScriptAlias directories).
13611 Changes with Apache 0.8.10 18 Aug 1995
13613 *) AllowOverride applies to the named directory, and not just
13614 subdirectories. [David Robinson]
13616 *) Do locking for accept() exclusion (on systems that need it)
13617 using a special file created for the purpose in /usr/tmp, and
13618 not the error log; using the error log causes real problems
13619 if it's NFS-mounted; this is known to be the cause of a whole
13620 lot of "server hang" problems with Solaris. [David Robinson;
13621 thanks to Merten Schumann for help diagnosing the problem].
13623 Changes with Apache 0.8.9 12 Aug 1995
13625 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
13627 *) Nested includes see environment variables of the including document,
13628 for NCSA bug-compatibility (some sites have standard footer includes
13629 which try to print out the last-modified date). [Eric Hagberg/Robert
13632 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
13633 URI as a CGI script, even if it would have been treated as something
13634 else if requested directly, for NCSA back-compatibility. (Note that
13635 this means that people who know the name of the script can see the
13636 code just by asking for it). [Robert Thau]
13638 *) New version of dbmmanage script included in support directory as
13641 *) Check if scoreboard file couldn't be opened, and say so, rather
13642 then going insane [David Robinson]
13644 *) POST to CGI works on A/UX [Jim Jagielski]
13646 *) AddIcon and AddAlt commands work properly [Rob Hartill]
13648 *) NCSA server push works properly --- the Arena bug compatibility
13649 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
13650 if you still want the workaround). [Rob Hartill]
13652 *) If client didn't submit any Accept-encodings, ignore encodings in
13653 content negotiation. (NB this will all have to be reworked anyway
13654 for the new HTTP draft). [Florent Guillaume]
13656 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
13658 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
13660 *) Give Redirect priority over Alias, for NCSA bug compatibility
13663 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
13664 paralleling earlier bug fix for CGI [David Robinson]
13666 *) If DBM auth is improperly configured, report a server error and don't
13669 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
13670 it seems to work well enough without it (even in a 10 hits/sec
13671 workout), and the overhead for the locking under A/UX is
13672 alarmingly high (though it is very low on other systems).
13673 [Eric Hagberg, Jim Jagielski]
13675 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
13677 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
13678 Behlendorf/Eric Hagberg]
13680 *) More improvements to default Configuration for A/UX [Jim Jagielski]
13682 *) Compiles clean on NEXT [Rob Hartill]
13684 *) Compiles clean on SGI [Robert Thau]
13686 Changes with Apache 0.8.8 08 Aug 1995
13688 *) SunOS library prototypes now never included unless explicitly
13689 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
13690 people using GNU libc on SunOS are screwed by prototypes for the
13693 (Those who wish to compile clean with gcc -Wall on a standard
13694 SunOS setup need the prototypes, and may obtain them using
13695 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
13696 with nonstandard libraries are presumably competent to make their
13699 *) Strips trailing '/' characters off both args to the Alias command,
13700 to make 'Alias /foo/ /bar/' work.
13702 Changes with Apache 0.8.7 03 Aug 1995
13704 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
13705 [reported by David Robinson]
13707 *) Compiles clean on OSF/1 [David Robinson]
13709 *) Added some of the more recent significant changes (AddLanguage stuff,
13710 experimental LogFormat support) to CHANGES file in distribution root
13713 Changes with Apache 0.8.6 02 Aug 1995
13715 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
13716 (If you actually wanted a conditional GET which bypassed the cache, you
13717 couldn't get it). [Reported by Roy Fielding]
13719 *) Properly terminate headers on '304 Not Modified' replies to conditional
13720 GETs --- no browser we can find cares much, but the CERN proxy chokes.
13721 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
13723 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
13725 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
13726 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
13727 and older versions don't set the __SUNPRO_C preprocessor variable). On
13728 all other systems, these are never used anyway. [Reported by Mark Cox].
13730 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
13732 Changes with Apache 0.8.5 01 Aug 1995
13734 *) Added last-minute configurable log experiment, as optional module
13736 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
13737 properly. (One-line fix to http_protocol.c).
13739 *) Work around bogus behavior when reloading from Netscape.
13740 It's Netscape's bug --- for some reason they expect a request with
13741 If-modified-since: to not function as a conditional GET if it also
13742 comes with Pragma: no-cache, which is way out of line with the HTTP
13743 spec (according to Roy Fielding, the redactor).
13745 *) Added parameter to set maximum number of server processes.
13747 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
13750 *) IdentityCheck bugfix [Chuck Murcko].
13752 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
13754 *) More sample config file corrections; add extension to AddType for
13755 *.asis, move AddType generic description to its proper place, and
13756 fix miscellaneous typos. [ Alexei Kosut ]
13758 *) Deleted the *other* reference to the regents from the Berkeley
13759 legal disclaimer (everyplace).
13761 *) Nuked Shambhala name from src/README; had already cleaned it out
13762 of everywhere else.
13764 Changes with Apache 0.8.4
13766 *) Changes to server-pool management parms --- renamed current
13767 StartServers to MinSpareServers, created separate StartServers
13768 parameter which means what it says, and renamed MaxServers to
13769 MaxSpareServers (though the old name still works, for NCSA 1.4
13770 back-compatibility). The old names were generally regarded as
13771 too confusing. Also altered "docs" in sample config files.
13773 *) More improvements to default config files ---
13774 sample directives (commented out) for XBitHack, BindAddress,
13775 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
13776 defaults, AddTypes for send-as-is and imagemap magic types, and
13777 improvements to samples for DirectoryIndex [Alexei Kosut]
13779 *) Yet more improvements to default config files --- changes to
13780 Alexei's sample AddLanguage directives, and sample LanguagePriority
13781 [ Florent Guillaume ]
13783 *) Set config file locations properly if not set in httpd.conf
13786 *) Don't escape URIs in internal redirects multiple times; don't
13787 do that when translating PATH_INFO to PATH_TRANSLATED either.
13790 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
13792 Changes with Apache 0.8.3
13794 *) Edited distribution README to *briefly* summarize installation
13795 procedures, and give a pointer to the INSTALL file in the src/
13798 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
13799 recent NCSA distributions.
13801 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
13802 exist for the same directory, use both and don't segfault. [Reported
13805 *) Proper makefile dependencies [David Robinson]
13807 *) Note (re)starts in error log --- reported by Rob Hartill.
13809 *) Only call no2slash() after get_path_info() has been done, to
13810 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
13811 reported by Andrew Wilson, though this one is probably a real bug]
13813 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
13814 dump core when Referer is not supplied. [Randy Terbush]
13816 *) Lightly edited sample config files to refer people to our documentation
13817 instead of NCSA's, and to list Rob McCool as *original* author (also
13818 deleted his old, and no doubt non-functional email address). Would be
13819 nice to have examples of new features...
13821 Changes with Apache 0.8.2 19 Jul 1995
13823 *) Added AddLanuage code [Florent Guillaume]
13825 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
13827 *) All sorts of problems when MultiViews finds a directory. It would
13828 be nice if mod_dir.c was robust enough to handle that, but for now,
13829 just punt. [reported by Brian Behlendorf]
13831 *) Wait for all children on restart, to make sure that the old socket
13832 is gone and we can reopen it. [reported by Randy Terbush]
13834 *) Imagemap module is enabled in default Configuration
13836 *) RefererLog and UserAgentLog modules properly default the logfile
13839 *) Mark Cox's mod_cookies added to the distribution as an optional
13840 module (commented out in the default Configuration, and noted as
13841 an experiment, along with mod_dld). [Mark Cox]
13843 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
13845 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
13847 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
13849 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
13852 Changes with Apache 0.8.1
13854 *) New imagemap module [Randy Terbush]
13856 *) Replacement referer log module with NCSA-compatible RefererIgnore
13857 [Matthew Gray again]
13859 *) Don't mung directory listings with very long filenames.
13860 [Florent Guillaume]
13862 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
13864 *) New config script. See INSTALL for info. [Robert Thau]
13866 *) Scoreboard mechanism for regulating the number of extant server
13867 processes. MaxServers and StartServers defaults are the same as
13868 for NCSA, but the meanings are slightly different. (Actually,
13869 I should probably lower the MaxServers default to 10).
13871 Before asking for a new connection, each server process checks
13872 the number of other servers which are also waiting for a
13873 connection. If there are more than MaxServers, it quietly dies
13874 off. Conversely, every second, the root, or caretaker, process
13875 looks to see how many servers are waiting for a new connection;
13876 if there are fewer than StartServers, it starts a new one. This
13877 does not depend on the number of server processes already extant.
13878 The accounting is arranged through a "scoreboard" file, named
13879 /tmp/htstatus.*, on which each process has an independent file
13880 descriptor (they need to seek without interference).
13882 The end effect is that MaxServers is the maximum number of
13883 servers on an *inactive* server machine, but more will be forked
13884 off to handle unusually heavy loads (or unusually slow clients);
13885 these will die off when they are no longer needed --- without
13886 reverting to the overhead of full forking operation. There is a
13887 hard maximum of 150 server processes compiled in, largely to
13888 avoid forking out of control and dragging the machine down.
13889 (This is arguably too high).
13891 In my server endurance tests, this mechanism did not appear to
13892 impose any significant overhead, even after I forced it to put the
13893 scoreboard file on a normal filesystem (which might have more
13894 overhead than tmpfs). [Robert Thau]
13896 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
13899 *) Read .htaccess files even in directory with <Directory> section.
13900 (Former incompatibility noted on mailing list, now fixed). [Robert
13903 *) "HEAD /" gives the client a "Bad Request" error message, rather
13904 than trying to send no body *and* no headers. [Cliff Skolnick].
13906 *) Don't produce double error reports for some very obscure cases
13907 mainly involving auth configuration (the "all modules decline to
13908 handle" case which is a sure sign of a server bug in most cases,
13909 but also happens when authentication is badly misconfigured).
13912 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
13913 it's *for*, and this sort of thing really shouldn't be cluttering
13914 up the Makefile). [Robert Thau]
13916 *) Incidental code cleanups in http_main.c --- stop dragging
13917 sa_client around; just declare it where used. [Robert Thau]
13919 *) Another acc-related fix. (It doesn't like const char
13920 in some places...). [Mark Cox]
13922 Changes with Shambhala 0.6.1 13 Jul 1995
13924 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
13925 Also, fixed auth typo in http_protocol.c unmasked by this fix.
13927 *) Compiles clean with acc on SunOS [Paul Sutton]
13929 *) Reordered modules in modules.c so that Redirect takes priority
13930 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
13931 believe it or not, he has an actual site with a ScriptAlias and
13932 a Redirect declared for the *exact same directory*. Even *my*
13933 compatibility fetish wouldn't motivate me to fix this if the fix
13934 required any effort, but it doesn't, so what the hey.
13936 *) Fixed to properly default several server_rec fields for virtual
13937 servers from the corresponding fields in the main server_rec.
13938 [Cliff Skolnick --- 'port' was a particular irritant].
13940 *) No longer kills off nph- child processes before they are
13941 finished sending output. [Matthew Gray]
13943 Changes with Shambhala 0.6.0 10 Jul 1995
13945 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
13946 the connection to the client in an "aborted" state, but otherwise
13947 allow whatever handlers are running to clean up. hard_timeout()s
13948 abort the request in progress completely; anything not tied to some
13949 resource pool cleanup will leak. They're still around because I
13950 haven't yet come up with a more elegant way of handling
13951 timeouts when talking to something that isn't the client. The
13952 default_handler and the dir_handler now use soft timeouts, largely
13953 so I can test the feature. [Robert Thau]
13955 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
13956 the case of log handlers dying prematurely is probably handled VERY
13957 gracelessly at this point, and if the logger stops reading input,
13958 the server will hang. (It is known to correctly restart the
13959 logging process on server restart; this is (should be!) going through
13960 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
13961 script). [Robert Thau]
13963 *) asis files supported (new module). [Robert Thau]
13965 *) IdentityCheck code is compiled in, but has not been tested. (I
13966 don't know anyone who runs identd). [Robert Thau]
13968 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
13969 came in with the request, for NCSA bug-compatibility. [Robert Thau]
13971 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
13973 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
13974 as timeouts are not in scope. [Robert Thau]
13976 *) quoted-string args in config files now handled correctly (doesn't drop
13977 the last character). [Robert Thau; reported by Randy Terbush]
13979 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
13980 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
13982 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
13983 default default type); the former default default behavior when all
13984 type-checkers defaulted had been a core dump. [Paul Sutton]
13986 *) Copy filenames out of the struct dirent when indexing
13987 directories. (On Linux, readdir() returns a pointer to the same
13988 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
13990 Changes with Shambhala 0.5.3 [not released]
13992 *) Default response handler notes "file not found" in the error log,
13993 if the file was not found. [Cliff Skolnick].
13995 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
13996 code no longer sets up bogus PATH_INFO which fakes out the directory
13997 handler). [Cliff Skolnick]
13999 Changes with Shambhala 0.5.2 06 Jul 1995
14001 *) Changes to http_main.c --- root server no longer plays silly
14002 games with SIGCHLD, and so now detects and replaces dying
14003 children. Child processes just die on SIGTERM, without taking
14004 the whole process group with them. Potential problem --- if any
14005 child process refuses to die, we hang in restart.
14006 MaxRequestsPerChild may still not work, but it certainly works
14007 better than it did before this! [Robert Thau]
14009 *) mod_dir.c bug fixes: ReadmeName and HeaderName
14010 work (or work better, at least); over-long description lines
14011 properly terminated. [Mark Cox]
14013 *) http_request.c now calls unescape_url() more places where it
14014 should [Paul Sutton].
14016 *) More directory handling bugs (reported by Cox)
14017 Parent Directory link is now set correctly. [Robert Thau]
14019 Changes with Shambhala 0.5.1 04 Jul 1995
14021 *) Generalized cleanup interface in alloc.c --- any function can be
14022 registered with alloc.c as a cleanup for a resource pool;
14023 tracking of files and file descriptors has been reimplemented in
14024 terms of this interface, so I can give it some sort of a test.
14027 *) More changes in alloc.c --- new cleanup_for_exec() function,
14028 which tracks down and closes all file descriptors which have been
14029 registered with the alloc.c machinery before the server exec()s a
14030 child process for CGI or <!--#exec-->. CGI children now get
14031 started with exactly three file descriptors open. Hopefully,
14032 this cures the problem Rob H. was having with overly persistent
14033 CGI connections. [Robert Thau]
14035 *) Mutual exclusion around the accept() in child_main() --- this is
14036 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
14037 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
14038 This uses fcntl(F_SETLK,...) on the error log descriptor because
14039 flock() on that descriptor won't work on systems which have BSD
14040 flock() semantics, including (I think) Linux 1.3 and Solaris.
14042 This does work on SunOS (when the server is idle, only one
14043 process in the pool is waiting on accept()); it *ought* to work
14044 on the other systems. [Robert Thau]
14046 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
14048 *) sizeof(*sa_client) bugfix from [Rob Hartill]
14050 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
14052 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
14053 be unnecessary if I go to the revised timeout-handling scheme).
14056 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
14057 string) even if none came in with the request. [Robert Thau]
14059 *) CHANGES file added to distribution ;-).
14061 Changes with Shambhala 0.4.5
14063 *) mod_dld --- early dynamic loading support [rst]
14064 *) Add wildcard content handlers for XBITHACK; default_hander now
14065 invoked with that mechanism (as a handler hanging off mod_core) [rst]
14066 *) XBITHACK supported as a wildcard content-handler, and
14067 configurable at run-time (not just at compile time, as in the
14068 "patchy server" releases) [rst]
14070 Changes with Shambhala 0.4.4 30 Jun 1995
14072 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
14073 *) Handle Addtype x/y .z [rst, reported by Cox]
14075 Changes with Shambhala 0.4.3
14077 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
14078 synonymous [rst, terbush]
14080 Changes with Shambhala 0.4.1 28 Jun 1995
14082 *) First-cut virtual host implementation; some refit in the config
14083 reading code, and log management, was necessary to support this [rst]
14084 *) Sub-pool machinery, originally added to avoid excessive storage
14085 allocation on listings of large directories (which turned out to
14086 be the problem that the 0.3 storage accounting was added to
14087 find). Subrequests and mod_dir changed to use subpools. [rst]
14088 *) More memory debugging --- free list consistency checks. [rst]
14089 *) Added err_headers to request_rec, with support elsewhere [rst]
14090 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
14092 Changes with Shambhala 0.3 19 Jun 1995
14094 *) Switch ONE_PROCESS to a runtime command-line option (-X)
14095 *) Don't compile in mod_ai_backcompat by default
14096 *) Switch name of server from Apache to Shambhala in Makefile
14097 *) Add some accounting routines to track memory usage in the pools,
14100 Changes with Shambhala 0.2
14102 *) Set DOCUMENT_ROOT CGI variable
14103 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
14104 *) Add critical section protection to handling of cleanup structures
14106 *) Significant code reorg within the server core to group related
14107 functions together [rst]
14108 *) Correctly handle clients that hang up before sending any request
14110 *) Replace dying child processes. [rst]
14112 Changes with Shambhala 0.1 12 Jun 1995
14114 Major rewrite of the pre-existing "patchy server" codebase, by
14115 Robert Thau (rst). Significant portions of the server code, such
14116 as configuration-file handling and HTTP authentication support,
14117 were ripped out and rewritten from scratch. Code that was not
14118 completely rewritten was significantly altered.
14120 Major changes with this release include:
14122 *) Introduction of the module API; in request handling, the central
14123 machinery just dispatches to various modules, which actually do
14124 most of the work. Configuration handling is similar --- modules
14125 declare their own commands, and the central machinery just
14126 dispatches to them.
14128 API features from shambhala/0.1 were substantially unchanged in
14129 Apache 1.0 and 1.1. (1.0 API features not yet present in this
14130 release, such as wildcard handlers and subpools, were added in
14131 subsequent Shambhala releases, and were also generally rst's
14134 *) This release included the following modules:
14136 mod_access (access control --- allow and deny directives),
14137 mod_alias (Alias and Redirect commands),
14138 mod_auth (straight HTTP authentication, based on flat-files)
14139 mod_auth_dbm (same, with dbm files)
14140 mod_cgi (CGI scripts and, in this release, ScriptAlias)
14141 mod_common_log (CLF access logs; later renamed mod_log_common)
14142 mod_dir (directory indexing)
14143 mod_include (server-side includes)
14144 mod_mime (AddType directives)
14145 mod_negotiation (content negotiation)
14146 mod_userdir (support for users' public_html directories)
14148 It also included a mod_ai_backcompat, which was a private hack
14149 for back-compatibility with rst's own AI-lab servers.
14151 All of these modules were substantially complete, and functional
14152 or nearly so (a few, which implemented features not in use at
14153 Thau's site, required patches of a few lines).
14155 *) sub-request machinery, to allow modules to determine how other
14156 modules would assign MIME types to a given file, or optionally
14157 serve its content (this is heavily used by mod_dir, mod_include
14158 and mod_negotiation).
14160 *) Resource pool system for keeping track of memory allocated and
14161 files opened in service of a particular request. Much of the
14162 code in the modules (when they weren't rewrites) was adjusted to
14163 replace a pervasive convention of using fixed-size buffers on
14164 the stack with an equally pervasive convention of using memory
14165 allocated with palloc().
14167 *) Reorganization of data structures associated with a given
14168 request to eliminate use of global variables and the troublesome
14169 unmunge_name function (used in NCSA and early Apache releases to
14170 attempt to determine the URI which mapped to a given filename
14171 --- a difficult proposition, given that it is easy to produce
14172 setups in which multiple URIs map to the same file).
14174 *) Source files renamed and rearranged
14176 *) Very simple pre-forking behavior --- parent process forked off a
14177 fixed number of children, and then just waited for SIGHUP.
14179 *) Other more minor changes too numerous to list.
14181 This release included modified versions of a lot of code from the
14182 Apache 0.6.4 public release, plus an early pre-forking patch
14183 codeveloped by Robert Thau and Rob Hartill.
14185 Changes with Apache 0.7.3 20 Jun 1995
14187 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
14188 were incorporated by Rob Hartill on the main branch while Robert Thau
14189 worked on the Shambhala rewrite above. Most were merged into the
14190 Shambala architecture after Apache 0.8.0.
14192 Changes with Apache 0.6.4 13 May 1995
14194 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
14197 Changes with Apache 0.5.1 10 Apr 1995
14199 Changes with Apache 0.4 02 Apr 1995
14201 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
14204 Changes with Apache 0.3 24 Mar 1995
14206 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
14209 Changes with Apache 0.2 18 Mar 1995
14211 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
14212 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
14213 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
