2 Changes with Apache 2.3.0
3 [Remove entries to the current 2.0 and 2.2 section below, when backported]
5 *) mod_proxy_http: Do send keep-alive header if the client sent
6 connection: keep-alive and do not close backend connection if the client
7 sent connection: close. PR 38524. [Ruediger Pluem, Joe Orton]
9 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
10 [Chris Darroch <chrisd pearsoncmg.com>]
12 *) mod_charset_lite: Remove Content-Length when output filter can
13 invalidate it. Warn when input filter can invalidate it.
16 *) Ensure that the proper status line is written to the client, fixing
17 incorrect status lines caused by filters which modify r->status without
18 resetting r->status_line, such as the built-in byterange filter.
21 *) mod_ssl: Fix spurious hostname mismatch warning for valid
22 wildcard certificates. PR 37911. [Nick Burch <nick torchbox.com>]
24 *) mod_proxy: Fix KeepAlives not being allowed and set to
25 backend servers. PR 38602. [Ruediger Pluem, Jim Jagielski]
27 *) Correctly initialize mod_proxy workers, which use a
28 combination of local and shared datasets. Adjust logging
29 to better trace usage. PR 38403. [Jim Jagielski]
31 *) Respect GracefulShutdownTimeout in the worker and event MPMs.
32 [Chris Darroch <chrisd pearsoncmg.com>, Garrett Rooney]
34 *) mod_proxy_balancer: Do not overwrite the status of initialized workers and
35 respect the configured status of uninitilized workers when creating a new
36 child process. [Ruediger Pluem]
38 *) mod_speling: Stop crashing with certain non-file requests. [Jeff Trawick]
40 *) mod_proxy_ajp: Support common headers of the AJP protocol in responses.
41 PR 38340. [Aleksey Pesternikov <apesternikov yahoo.com>]
43 *) core: Reject invalid Expect header immediately. PR 38123.
46 *) Authz: Add the new module mod_authn_core that will provide common
47 authn directives such as 'AuthType', 'AuthName'. Move the directives
48 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
49 into mod_authn_core. [Brad Nicholes]
51 *) Authz: Mark the directives 'Order', 'Allow', 'Deny' and 'Satisfy' as
52 deprecated and move them into the new module mod_access_compat which
53 can be loaded to provide backwards compatibility for these directives.
56 *) Authz: Move the 'Require' directive from the core module as well as
57 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
58 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
59 logic into the authorization processing. [Brad Nicholes]
61 *) Authz: Add the new module mod_authz_core which acts as the
62 authorization provider vector and contains common authz
63 directives. [Brad Nicholes]
65 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
66 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
68 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
69 host-based access control provided by mod_authz_host and invoked
70 through the 'Require' directive. [Brad Nicholes]
72 *) Authz: Convert all of the authz modules from hook based to
73 provider based. [Brad Nicholes]

84 [Justin Erenkrantz, Roy T. Fielding, Jim Jagielski, Ruediger Pluem]
86 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
88 *) Fix typo in ProxyStatus syntax error message.
89 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
91 *) Asynchronous write completion for the Event MPM. [Brian Pane]
93 *) Added an End-Of-Request bucket type. The logging of a request and
94 the freeing of its pool are now done when the EOR bucket is destroyed.
95 This has the effect of delaying the logging until right after the last
96 of the response is sent; ap_core_output_filter() calls the access logger
97 indirectly when it destroys the EOR bucket. [Brian Pane]
99 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
100 and the format of statistical output has changed. [Colm MacCarthaigh]
102 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
104 *) Added new connection states for handler and write completion
107 *) New module: mod_authn_dbd [Nick Kew]
109 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
112 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
113 allowing string-valued client certificate attributes to be used for
114 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
115 [Martin Kraemer, David Reid]
117 Changes with Apache 2.2.1
119 *) SECURITY: CVE-2005-3357 (cve.mitre.org)
120 mod_ssl: Fix a possible crash during access control checks if a
121 non-SSL request is processed for an SSL vhost (such as the
122 "HTTP request received on SSL port" error message when an 400
123 ErrorDocument is configured, or if using "SSLEngine optional").

126 *) SECURITY: CVE-2005-3352 (cve.mitre.org)
127 mod_imagemap: Escape untrusted referer header before outputting
128 in HTML to avoid potential cross-site scripting. Change also
129 made to ap_escape_html so we escape quotes. Reported by JPCERT.
132 *) mod_cache: Make caching of reverse proxies possible again. PR 38017.
135 *) Modify apr[util] .h detection to avoid breakage on VPATH builds
136 using Solaris make (amoung others) and avoid breakage in ./buildconf
137 when srclib/apr[-util] are symlinks rather than directories proper.
140 *) Chunk filter: Fix chunk filter to create correct chunks in the case that
141 a flush bucket is surrounded by data buckets. [Ruediger Pluem]
143 *) Fix syntax error in httpd.h with strict compilers. PR 38740.
144 [Per Olausson <pao darkheim.freeserve.co.uk>]

157 Changes with Apache 2.2.0
159 *) mod_negotiation: Minor performance tweak by reusing already calculated
161 [Ruediger Pluem, Christophe Jaillet <christophe.jaillet wanadoo.fr>]
163 *) Remove support for 'On' and 'Off' for AuthBasicProvider and
164 AuthDigestProvider. [Joshua Slive, Justin Erenkrantz]
166 *) Add in new UseCanonicalPhysicalPort directive, which controls
167 whether or not Apache will ever use the actual physical port
168 when constructing the canonical port number. [Jim Jagielski]

186 *) mod_cache: Create new filters CACHE_OUT_SUBREQ / CACHE_SAVE_SUBREQ which
187 only differ by the type from CACHE_OUT / CACHE_SAVE to ensure that
188 subrequests to non local resources work again. [Ruediger Pluem]
190 *) mod_proxy: Do not lowercase the entire worker name of a BalancerMember
191 since this breaks case sensitive URI's. PR36906. [Ruediger Pluem]
193 *) core: AddOutputFilterByType is ignored for proxied requests. PR31226.
194 [Joe Orton, Ruediger Pluem]
196 *) mod_proxy_http: Prevent data corruption of POST request bodies when
197 client accesses proxied resources with SSL. PR37145.
198 [Ruediger Pluem, William Rowe]
200 *) mod_proxy_balancer: BalancerManager and proxies correctly handle
201 member workers with paths. PR36816. [Ruediger Pluem, Jim Jagielski]
203 *) mod_log_config: %{hextid}P will log the thread id in hex with APR
204 versions 1.2.0 or higher. [Jeff Trawick]

219 [William Barker <william.barker wilshire.com>, Ruediger Pluem]
221 *) Elimiated the NET_TIME filter, restructuring the timeout logic.
222 This provides a working mod_echo on all platforms, and ensures any
223 custom protocol module is at least given an initial timeout value
224 based on the <VirtualHost > context's Timeout directive.
227 *) mod_proxy: Run the request_status hook also if there are no free workers
228 or all workers are in error state.

2828 Changes with Apache 2.0.43
2830 *) SECURITY: CVE-2002-0840 (cve.mitre.org)
2831 HTML-escape the address produced by ap_server_signature() against
2832 this cross-site scripting vulnerability exposed by the directive
2833 'UseCanonicalName Off'. Also HTML-escape the SERVER_NAME
2834 environment variable for CGI and SSI requests. It's safe to
2835 escape as only the '<', '>', and '&' characters are affected,
2836 which won't appear in a valid hostname. Reported by Matthew
2837 Murphy <mattmurphy kc.rr.com>. [Brian Pane]
2839 *) Fix a core dump in mod_cache when it attemtped to store uncopyable
2840 buckets. This happened, for instance, when a file to be cached
2841 contained SSI tags to execute a CGI script (passed as a pipe
2842 bucket). [Paul J. Reder]
2844 *) Ensure that output already available is flushed to the network
2845 when the content-length filter realizes that no new output will
2846 be available for a while. This helps some streaming CGIs as
2847 well as some other dynamically-generated content. [Jeff Trawick]
2849 *) Fix a mutex problem in mod_ssl session cache support which
2850 could lead to an infinite loop. PR 12705
2851 [Amund Elstad <amund.elstad ergo.no>, Jeff Trawick]
2853 *) SECURITY: CVE-2002-1156 (cve.mitre.org)
2854 Fix the exposure of CGI source when a POST request is sent to
2855 a location where both DAV and CGI are enabled. [Ryan Bloom]
2857 *) Allow the UserDir directive to accept a list of directories.
2858 This matches what Apache 1.3 does. Also add documentation for
2859 this feature. [Jay Ball <jay veggiespam.com>]
2861 *) New Module: mod_logio. adds the ability to log bytes sent and
2862 received. [Bojan Smojver <bojan rexursive.com>]
2864 *) SuExec needs to use the same default directory as the rest of
2865 server, namely /usr/local/apache2.

2868 *) Get mod_auth_ldap to retry connections on LDAP_SERVER_DOWN.
2869 [Thomas Bennett <thomas.bennett eds.com>, Graham Leggett]
2871 *) Make sure the contents of the WWW-Authenticate header is
2872 passed on a 4xx error by proxy. Previously all headers
2873 were dropped, resulting in the browser being unable to
2874 authenticate. [Dr Richard Reiner <rreiner fscinternet.com>,

2877 <dhenderson fscinternet.com>]
2879 *) Make mod_cache's CacheMaxStreamingBuffer directive work
2880 properly for virtual hosts that override server-wide mod_cache
2881 setttings. [Matthieu Estrade <estrade-m ifrance.com>]
2883 *) Add -p option to apxs to allow programs to be compiled with apxs.
2886 Changes with Apache 2.0.42
2888 *) SECURITY: CVE-2002-1593 (cve.mitre.org) [CERT VU#406121]
2889 mod_dav: Check for versioning hooks before using them.
2892 Changes with Apache 2.0.41
2894 *) The protocol version (eg: HTTP/1.1) in the request line parsing
2895 is now case insensitive. [Jim Jagielski]
2897 *) Allow AddOutputFilterByType to add multiple filters per directive.
2900 *) Remove warnings with Sun's Forte compiler. [Justin Erenkrantz]
2902 *) Fixed mod_disk_cache's generation of 304s

2905 *) Add support for using fnmatch patterns in the final path
2906 segment of an Include statement (eg.. include /foo/bar/*.conf).
2907 and remove the noise on stderr during config dir processing.
2908 [Joe Orton <jorton redhat.com>]
2910 *) mod_cache: cache_storage.c. Add the hostname and any request
2911 args to the key generated for caching. This provides a unique
2912 key for each virtual host and for each request with unique
2913 args. [Paul J. Reder, args code provided by Kris Verbeeck]
2915 *) mod_cache: Do not cache responses to GET requests with query
2916 URLs if the origin server does not explicitly provide an

2932 *) Add ModMimeUsePathInfo directive. [Justin Erenkrantz]
2934 *) mod_cache: added support for caching streamed responses (proxy,
2935 CGI, etc) with optional CacheMaxStreamingBuffer setting [Brian Pane]
2937 *) Add image/x-icon to httpd.conf PR 10993.

2940 *) Fix FileETags none operation. PR 12207.
2941 [Justin Erenkrantz, Andrew Ho <andrew tellme.com>]
2943 *) Restored the experimental leader/followers MPM to working
2944 condition and converted its thread synchronization from
2945 mutexes to atomic CAS. [Brian Pane]
2947 *) Fix Logic on non-html file removal in mod_deflate

2950 *) Fix "ab -g"'s truncated year: the last digit was cut off.
2951 [Leon Brocard <acme astray.com>]
2953 *) mod_rewrite can now sets cookies in err_headers, uses the correct
2954 expiry date, and can now set the path as well
2955 PR 12132,12181,12172.
2956 [Ian Holsman / Rob Cromwell <apachechangelog robcromwell.com>]
2958 *) The content-length filter no longer tries to buffer up
2959 the entire output of a long-running request before sending
2960 anything to the client. [Brian Pane]
2962 *) Win32: Lower the default stack size from 1MB to 256K. This will
2963 allow around 8000 threads to be started per child process.
2964 'EDITBIN /STACK:size apache.exe' can be used to change this
2965 value directly in the apache.exe executable.
2968 *) Win32: Implement ThreadLimit directive in the Windows MPM.
2971 *) Remove CacheOn config directive since it is set but never checked.
2972 No sense wasting cycles on unused code. Besides, the only truly
2973 bug free code is deleted code. :) [Paul J. Reder]
2975 *) BufferLogs are now run-time enabled, and the log_config now has 2 new
2976 callbacks to allow a 3rd party module to actually do the writing of the
2977 log file [Ian Holsman]
2979 *) Correct ISAPIReadAheadBuffer to default to 49152, per mod_isapi docs.
2980 [André Malo, Astrid Keßler <kess kess-net.de>]
2982 *) Fix Segfault in mod_cache. [Kris Verbeeck <Kris.Verbeeck ubizen.com>]

2985 function of the mod_env module. PR 11791
2988 *) New option to ServerTokens 'maj[or]'. Only show the major version
2989 Also Surfaced this directive in the standard config (default FULL)
2992 *) Change mod_rewrite to use apr-util's dbm support for dbm rewrite
2993 maps. The dbm type (e.g., ndbm, gdbm) can be specified on the
2994 RewriteMap directive. PR 10644 [Jeff Trawick]
2996 *) Fixed mod_rewrite's RewriteMap prg: support so that request/response
2997 pairs will no longer get out of sync with each other. PR 9534
3000 *) Fixes required to get quoted and escaped command args working in
3001 mod_ext_filter. PR 11793 [Paul J. Reder]
3003 *) mod-proxy: handle proxied responses with no status lines

3006 *) Fix bug where environment or command line arguments containing
3007 non-ASCII-7 characters would cause the Win32 child process creation
3008 to fail. PR 11854 [William Rowe]

3011 [Ian Darwin <Ian779 darwinsys.com>]
3013 *) thread safety & proxy-ftp [Alexey Panchenko <alexey liwest.ru>, Ian Holsman]
3015 *) mod_disk_cache works much better. This module should still
3016 be considered experimental. [Eric Prud'hommeaux]
3018 *) Performance improvement for keepalive requests: when setting
3019 aside a small file for potential concatenation with the next
3020 response on the connection, set aside the file descriptor rather
3021 than copying the file into the heap. [Brian Pane]
3023 *) Modified version check on openssl so that it finds the executable
3024 first and then performs a check of the version, only warning the
3025 user if they chose, or we selected, an old version of OpenSSL.
3026 This change also allows the code to work for non-openssl libraries
3027 selected via the --with-ssl=dir option, which can override the
3028 automated library check in any case. [Roy Fielding]
3030 Changes with Apache 2.0.40
3032 *) SECURITY: CVE-2002-0661 (cve.mitre.org)
3033 Close a very significant security hole that
3034 applies only to the Win32, OS2 and Netware platforms. Unix was not
3035 affected, Cygwin may be affected. Certain URIs will bypass security
3036 and allow users to invoke or access any file depending on the system
3037 configuration. Without upgrading, a single .conf change will close
3038 the vulnerability. Add the following directive in the global server
3039 httpd.conf context before any other Alias or Redirect directives;
3040 RedirectMatch 400 "\\\.\."
3041 Reported by Auriemma Luigi <bugtest sitoverde.com>.
3044 *) SECURITY: CVE-2002-0654 (cve.mitre.org)
3045 Close a path-revealing exposure in multiview type
3046 map negotiation (such as the default error documents) where the
3047 module would report the full path of the typemapped .var file when
3048 multiple documents or no documents could be served based on the mime
3049 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
3052 *) SECURITY: CVE-2002-0654 (cve.mitre.org)
3053 Close a path-revealing exposure in cgi/cgid when we
3054 fail to invoke a script. The modules would report "couldn't create
3055 child process /path-to-script/script.pl" revealing the full path
3056 of the script. Reported by Jim Race <jrace qualys.com>.
3059 *) Set aside the apr-iconv and apr_xlate() features for the Win32
3060 build of 2.0.40 so development can be completed. A patch, from
3061 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
3062 will be available for those that wish to work with apr-iconv.
3065 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
3066 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
3068 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
3069 set to 1, so we can exclude things from the general case with
3070 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
3072 *) Accept multiple leading /'s for requests within the DocumentRoot.
3073 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
3075 *) Solved the reports of .pdf byterange failures on Win32 alone.
3076 APR's sendfile for the win32 platform collapses header and trailer
3077 buffers into a single buffer. However, we destroyed the pointers
3078 to the header buffer if a trailer buffer was present. PR 10781
3081 *) mod_ext_filter: Add the ability to enable or disable a filter via
3082 an environment variable. Add the ability to register a filter of
3083 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
3085 *) Restore the ability to specify host names on Listen directives.
3086 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh yahoo.com>]
3088 *) When deciding on the default address family for listening sockets,
3089 make sure we can actually bind to an AF_INET6 socket before
3090 deciding that we should default to AF_INET6. This fixes a startup
3091 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
3093 *) Replace usage of atol() to parse strings when we might want a
3094 larger-than-long value with apr_atoll(), which returns long long.
3095 This allows HTTPD to deal with larger files correctly.
3096 [Shantonu Sen <ssen apple.com>]
3098 *) mod_ext_filter: Ignore any content-type parameters when checking if
3099 the response should be filtered. Previously, "intype=text/html"
3100 wouldn't match something like "text/html;charset=8859_1".
3103 *) mod_ext_filter: Set up environment variables for external programs.
3104 [Craig Sebenik <craig netapp.com>]
3106 *) Modified the HTTP_IN filter to immediately append the EOS (end of
3107 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
3108 the caller to determine that no content remains without prefetching
3109 additional POST body. [William Rowe]
3111 *) Get proxy ftp to work over IPv6. [Shoichi Sakane <sakane kame.net>]
3113 *) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml suse.de>]
3115 *) Update SuSE layout. [Peter Poeml <poeml suse.de>]
3117 *) Changes to the internationalized error documents:
3118 Comment them out in the default config file to make the default
3119 install as simple as possible; Correct the english 500 error to
3120 be more understandable; Add a Swedish translation.
3121 [Thomas Sjogren <thomas northernsecurity.net>,
3122 Erik Abele <erik codefaktor.de>, Rich Bowen, Joshua Slive]
3124 *) Increase the limit on file descriptors per process in apachectl.
3127 *) Fix a dependency error when building ApacheMonitor, so that Win32
3128 and MSVC now trust that the project is current (when it is).
3129 [James Cox <imajes php.net>]
3131 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
3132 [Arthur P. Smith <apsmith aps.org>, Jeff Trawick]
3134 *) APR-Util Renames pending have been completed [Thom May]
3136 *) Performance improvements for the code that reads request
3137 headers (ap_rgetline_core() and related functions) [Brian Pane]
3139 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
3140 to configure the maximum amount of memory the allocators will
3141 hold on to for reuse. Anything over the MaxMemFree threshold
3142 will be free()d. This directive is useful when uncommon large
3143 peaks occur in memory usage. It should _not_ be used to mask
3144 defective modules' memory use. [Sander Striker]
3146 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
3147 scripts would not result in a truncated response.
3148 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
3150 *) Add a filter_init parameter to the filter registration functions
3151 so that a filter can execute arbitrary code before the handlers
3152 are invoked. This resolves a problem where mod_include requests
3153 would incorrectly return a 304. [Justin Erenkrantz]
3155 *) Fix a long-standing bug in 2.0, CGI scripts were being called
3156 with relative paths instead of absolute paths. Apache 1.3 used
3157 absolute paths for everything except for SuExec, this brings back
3158 that standard. [Ryan Bloom]
3160 *) Fix infinite loop due to two HTTP_IN filters being present for
3161 internally redirected requests. PR 10146. [Justin Erenkrantz]
3163 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
3166 *) Fix mod_ext_filter to look in the main server for filter definitions
3167 when running in a vhost if the filter definition is not found in
3168 the vhost. PR 10147 [Jeff Trawick]
3170 *) Support WinNT CGI invocation through ScriptInterpreterSource
3171 'registry' for script interpreter paths and names with non-ascii
3172 characters in the executable filepath. [William Rowe]
3174 *) Support the -w flag on to keep the Win32 console open on error.
3177 *) Normalize the hostname value in the request_rec to all-lowercase
3178 [Perry Harrington <pedward webcom.com>]
3180 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
3181 extended characters (non US-ASCII) in non-utf8 format. This brings
3182 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
3183 to the cgi application itself. [William Rowe]
3185 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
3186 modules to bring them up to the current apr/apr-util APIs.
3189 *) Fix segfault in mod_mem_cache most frequently observed when
3190 serving the same file to multiple clients on an MP machine.
3193 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
3194 [Brian Degenhardt <bmd mp3.com>, Ian Holsman]
3196 *) Fix perchild to work with apachectl by adding -k support to perchild.
3197 PR 10074 [Jeff Trawick]
3199 *) Fix a silly htpasswd.c logic error that incorrectly reported that
3200 both -c and -n had been used. PR 9989 [Cliff Woolley]
3202 *) Fixed a mod_include error case in which no HTTP response was sent
3203 to the client if an shtml document contained an unterminated SSI
3204 directive [Brian Pane]
3206 *) Improve ap_get_client_block implementation by using APR-util brigade
3207 helper functions and relying on current filter assumptions.
3210 Changes with Apache 2.0.39
3212 *) Fixed a build problem in htpasswd.c on Win32.
3213 [Guenter Knauf <eflash gmx.net>, Cliff Woolley]
3215 Changes with Apache 2.0.38
3217 *) Rewrite htpasswd to use APR. The removes the annoying warning about
3218 tmpnam being unsafe. [Ryan Bloom]
3220 *) We must set the MIME-type for .shtml files to text/html if we want them
3221 to be parsed for SSI tags. Add the config for that to the default
3222 config file so that it is easier to enable .shtml parsing.
3223 [Dave Dyer <ddyer real-me.net>]
3225 *) Fixed a problem with 'make install' on ReliantUnix.
3226 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
3228 *) Make the default_handler catch all requests that aren't served by
3229 another handler. This also gets us to return a 404 if a directory
3230 is requested, there is no DirectoryIndex, and mod_autoindex isn't
3231 loaded. [Justin Erenkrantz]
3233 *) Fixed the handling of nested if-statements in shtml files.
3234 PR 9866 [Brian Pane]
3236 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
3237 into a directory different from the one that was configured. This
3238 also mirrors the root= feature from 1.3. We cannot use prefix=,
3239 because both APR and APR-util resolve their installation paths at
3240 configuration time. This means that there is no variable prefix
3241 to replace. [Andreas Hasenack <andreas netbank.com.br>]
3243 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
3244 These levels of AIX don't have a thundering herd problem with
3245 accept(). [Jeff Trawick]
3247 *) prefork MPM: Ignore mutex errors during graceful restart. For
3248 certain types of mutexes (particularly SysV semaphores), we
3249 should expect to occasionally fail to obtain or release the
3250 mutex during restart processing. [Jeff Trawick]
3252 *) Fix install-bindist.sh so that it finds any perl instead of just
3253 early perl 5.x versions. This is consistent with a build/install
3254 from source, and it allows the perl scripts installed by a bindist
3255 to work on systems with perl 5.6. [Jeff Trawick]
3257 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
3258 Tru64 (and probably some other platforms). [Jeff Trawick]
3260 *) Allow CGI scripts to return their Content-Length. This also fixes a
3261 hang on HEAD requests seen on certain platforms (such as FreeBSD).
3264 *) Added log rotation based on file size to the RotateLog support
3265 utility. [Brad Nicholes]
3267 *) Fix some casting in mod_rewrite which broke random maps.
3268 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
3270 Changes with Apache 2.0.37
3272 *) allow POST method over SSL when per-directory client cert
3273 authentication is used with 'SSLOptions +OptRenegotiate' enabled
3274 and a client cert was found in the ssl session cache.
3276 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
3277 session cache when there is no cert chain in the cache. prior to
3278 the fix this situation would result in a FORBIDDEN response and
3279 error message "Cannot find peer certificate chain"
3282 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
3283 one was already sent. PR 9644 [Jeff Trawick]
3285 *) Fix the display of the default name for the mime types config
3286 file. PR 9729 [Matthew Brecknell <mbrecknell orchestream.com>]

3290 of Apache.exe, in the case that Apache.exe resides in bin/.)
3291 Solves the case of ServerRoot /foo paths where /foo was not
3292 on the same drive as /winnt/system32. [William Rowe]
3294 *) Make 2.0's "AcceptMutex" startup message now "completely"
3295 match how 1.3 does it. [Jim Jagielski]
3297 *) Implement a fixed size memory cache using a priority queue
3300 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
3301 querying certain other variables from config_vars.mk. PR 9316
3304 *) Added the "detached" attribute to the cgi_exec_info_t internals
3305 so that Win32 and Netware won't create a new window or console
3306 for each CGI invoked. PR 8387
3307 [Brad Nicholes, William Rowe]
3309 *) Consolidated the command line parameters and attributes that are
3310 manipulated by the optional function ap_cgi_build_command() in
3311 mod_cgi into a single structure.
3314 *) Get rid of uninitialized value errors with "apxs -q" on certain
3315 variables. [Stas Bekman <stas stason.org>]

3318 besides server-root/build. PR 8453
3319 [Jeff Trawick and a host of others]
3321 *) Allow ap_discard_request_body to be called multiple times in the
3322 same request. Essentially, ap_http_filter keeps track of whether
3323 it has sent an EOS bucket up the stack, if so, it will only ever
3324 send an EOS bucket for this request.
3325 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
3327 *) Remove all special mod_ssl URIs. This also fixes the bug where
3328 redirecting (.*) will allow an SSL protected page to be viewed
3329 without SSL. [Ryan Bloom]
3331 *) Fix the binary build install script so that the build logic
3332 created by "apxs -g" will work when the user has a binary
3333 build. [Jeff Trawick]
3335 *) Allow instdso.sh to work with full paths to the shared module.
3338 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
3339 in module for NetWare [Brad Nicholes]
3341 *) Changed cgi and piped log behavior to accept 65536 characters
3342 on Win32 (matching Linux) before deadlocking between outputing
3343 client stdin, slurping the output from stdout and then the stderr
3344 stream. PR 8179 [William Rowe]
3346 *) Fixed Win32 wintty.exe support to assure the window title is valid.
3347 Elimiates possible gpfault or garbage title without the -t option.
3350 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use

3619 to the client in addition to being recorded in the error log.
3620 Prior to this change, ap_log_rerror() always sent warning
3621 messages to the client. In one case, a faulty CGI script caused
3622 the server to send a warning message to the client that contained
3623 the full path to the CGI script. This could be considered a
3624 minor security exposure. [Bill Stoddard]

3753 -DNO_DETACH except that it doesn't switch session ids).
3756 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)

3946 client. This prevents the backend server from being forced to hang
3947 around while the last few bytes are transmitted to a slow client.
3948 Fix the case where no error checking was performed on the final
3949 brigade in the loop. [Graham Leggett]
3951 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
3952 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
3953 hours. [Graham Leggett, Bill Stoddard]
3955 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
3956 for a undefined variable. [Ian Holsman]
3958 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
3959 when we can't get a socket in the specified address family. We may
3960 have gotten back an IPv6 address first and yet our system is not
3961 configured to allow IPv6 sockets. [Jeff Trawick]
3963 *) Be more careful about recursively removing CVS directories. Make
3964 sure that we aren't cd'ing to their home directory first. PR: 9993
3965 [Aaron Bannert, James LewisMoss <dres lewismoss.net>]
3967 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
3968 [Dirk-Jan Faber <dirk-jan selwerd.nl>, Aaron Bannert,
3969 Thom May <thom planetarytramp.net>]
3971 *) Rename the filter ordering priorities. The recent filtering fixes
3972 have showcased problems with their usage. Therefore, we need to
3973 rename them to increase the clarity. (CONTENT->RESOURCE,
3974 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
3976 Changes with Apache 2.0.33
3978 *) Fix a problem in the new --enable-layout functionality where
3979 it wouldn't allow overrides from variables like --prefix,
3980 --bindir, etc. [Thom May <thom planetarytramp.net>]
3982 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
3983 no longer hangs around waiting for the socket to close before
3984 returning exhaustive data. [Aaron Bannert]
3986 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
3987 [Thom May <thom planetarytramp.net>]
3989 *) Change mod_ssl to always do a full startup/teardown on restarts.
3990 this allows mod_ssl to be added to a server that is already
3991 running and makes it possible to add/change certs/keys after the
3992 server has been started. [Doug MacEachern]
3994 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
3995 This pipe must be a bidirectional 'console' style relay, which
3996 mod_ssl prints all prompts to the pipe's stdin, and reads the
3997 passphrases from the pipe's stdout. [William Rowe]
3999 *) Fix bug where --sysconfdir and --localstatedir were being
4000 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
4003 *) Fix --enable-layout to work again. Caution: When specifying
4004 --enable-layout, common arguments like --prefix, --exec-prefix,
4005 etc. will be ignored and the settings from the layout will be
4006 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]
4009 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
4010 regex pattern matching for the determination of which requests
4011 to use the remote proxy for. [Jim Jagielski]
4013 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
4015 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
4016 cruft in piped logs and rewritemap child processes.
4019 *) All instances of apr_lock_t have been removed and converted
4020 to one of the following new lock APIs: apr_thread_mutex.h,
4021 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
4022 use the apr_lock.h API, as the old API will soon be deprecated.
4025 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
4026 [Ralf S. Engelschall, Cliff Woolley]
4028 *) mod-include: make it handle flush'es and fix the 'false-alarm'
4029 [Justin Erenkrantz, Brian Pane, Ian Holsman]
4031 *) ap_get_*_filter_handle() functions to allow 3rd party modules
4032 to lookup filter handles so they can bypass the filter name
4033 lookup when adding filters to a request (via ap_add_*_filter_handle())
4034 [Ryan Morgan <rmorgan covalent.net>]
4036 *) Fix for multiple file buckets on Win32, where the first file
4037 bucket would cause the immediate closure of the socket on any
4038 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
4040 *) Correct Win32 failure of mmap of a segment beyond start of the
4041 file; fixes large SSL and similar transfers. [William Rowe]
4044 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
4045 multi-process mode to not "daemonize" while detaching from the
4046 controlling terminal. This is necessary for Apache to work with
4047 process-management tools like AIX's "System Resource Controller"
4048 as well as Dan Bernstein's "daemontools".
4049 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
4051 *) Convert mod_auth_digest to use the new apr_global_mutex_t
4052 type. [Aaron Bannert]
4054 *) fix bug in mod-include where it wouldn't send a unmatched
4055 part if it was at the end of a bucket [Ian Holsman]
4057 *) worker MPM: Improve logging of errors with the interface between
4058 the listener thread and worker threads. [Jeff Trawick]
4060 *) Some browsers ignore cookies that have been merged into a
4061 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
4062 are now unmerged in the http proxy before being sent to the
4063 client. [Graham Leggett]
4065 *) Fix a problem with proxy where each entry of a duplicated
4066 header such as Set-Cookie would overwrite and obliterate the
4067 previous value of the header, resulting in multiple header
4068 values (like cookies) going missing.
4069 [Graham Leggett, Joshua Slive]
4071 *) Add the server-limit and thread-limit values to the scoreboard
4072 for the sake of third-party applications.
4073 [Adam Sussman <myddryn vishnu.vidya.com>]
4075 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
4077 *) OS/390: Get make install to properly copy DSO modules.
4080 *) Win32: Fix bug in mod_status with displaying "Restart Time"
4081 and "Server uptime".
4084 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
4086 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
4088 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
4089 [David MacKenzie <djm pix.net>]
4091 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
4092 [David MacKenzie <djm pix.net>]
4094 *) Fix segfault and display error when SSLMutex file can not be
4095 created. [Adam Sussman <myddryn vishnu.vidya.com>]
4097 *) Add reference counting to mod_mem_cache cache objects to
4098 better manage removing objects from the cache.
4101 *) Change the verbage on the ScoreBoardFile in our default configs.
4102 Also change the default to be commented out (unspecified) so we
4103 get anonymous shared memory by default. [Aaron Bannert]
4105 *) Implement new ScoreBoardFile directive logic. This affects how
4106 we create the scoreboard's shared memory segment. If the directive
4107 is present, a name-based segment is created. If the directive is
4108 not present, first an anonymous segment is created, and if that
4109 fails, a name-based segment is created from a file of the name
4110 DEFAULT_SCOREBOARD. This gives third-party applications the
4111 ability to access our scoreboard. [Aaron Bannert]
4113 *) Allow mod_deflate to work with non-GET requests and properly send
4114 Content-Lengths. [Sander Striker <striker apache.org>]
4116 *) Fix ap_directory_merge() to correctly merge configs when there is
4117 no <Directory /> block. [Justin Erenkrantz, William Rowe]
4119 *) Remove spurious debug messsages that are normal under HTTP
4120 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
4122 *) Fix a bug in mod_cgid that would prevent proper shutdown death
4123 of the cgid process. [Aaron Bannert]
4125 *) Add signal handling back in to the worker MPM for the one_process
4126 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
4128 *) Performance: Reuse per-connection transaction pools in the
4129 worker MPM, rather than destroying and recreating them. [Brian Pane]
4131 *) Remove all signals from the worker MPM's child process. Instead,
4132 the parent uses the Pipe of Death for all communication with the
4133 child processes. [Ryan Bloom]
4135 Changes with Apache 2.0.32
4137 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
4138 default if the directive is not specified. This mirrors older
4139 behavior without changes to the httpd.conf. [William Rowe]
4141 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
4142 the service, mpm and logging code, and bugs in apr_file_open_stderr
4143 and apr_file_dup2 functions. Win2K/XP services have no handles
4144 associated for stdin/out/err, which caused unpredictable behavior
4145 in the prior release. [William Rowe, Bill Stoddard]
4147 *) Win32: simplify the Application Event Log messages, since there isn't
4148 likely to be 'more information in the error log' before an error log
4149 has been opened. [William Rowe]
4151 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
4152 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
4154 *) Win32: apache -k shutdown now behaves like apache -k stop.
4157 *) Fix prefork to not kill the parent if a child hits a resource shortage
4158 on accept(). [Greg Ames]
4160 *) Fix seg faults that occur when what should be the httpd request line
4161 starts with \r\n followed by garbage. [Greg Ames]
4163 *) Allow statically linked support binaries with the new
4164 --enable-static-support flag, and enable this behavior in
4165 the binbuild script. Also add a new --enable-static-htdbm
4166 flag. [Aaron Bannert]
4168 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
4169 do only one stat() call when generating the directory listings.
4172 *) Fix resolve_symlink to save the original symlink name if known.
4175 *) Be a bit more sane with regard to CanonicalNames. If the user has
4176 specified they want to use the CanonicalName, but they have not
4177 configured a port with the ServerName, then use the same port that
4178 the original request used. [Ryan Bloom and Ken Coar]
4180 *) In core_input_filter, check for an empty brigade after
4181 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
4182 client says it will post some data but we get FIN before any
4183 data arrives. [Jeff Trawick]
4185 *) Not being able to bind to the socket is a fatal error. We should
4186 print an error to the console, and return a non-zero status code.
4187 With these changes, all of the Unix MPMs do that correctly.
4190 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
4191 through to CGI scripts. PR 9163
4192 [Brian Reid <breid customlogic.com>,
4193 Zvi Har'El <rl math.technion.ac.il>]
4195 *) binbuild.sh: Make sure that we use the expat from our source
4196 tree so that there aren't any surprises on the target machine.
4199 *) mod_cgid: Add retry logic for when the daemon can't fork fast
4200 enough to keep up with new requests. Start using
4201 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
4202 when we can't talk to the daemon. [Jeff Trawick]
4204 *) apxs: LTFLAGS envvar can override default libtool options. Try
4205 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
4206 the covers. [Jeff Trawick]
4208 *) The Location: response header field, used for external
4209 redirect, *must* be an absoluteURI. The Redirect directive
4210 tested for that, but RedirectMatch didn't -- it would allow
4211 almost anything through. Now it will try to turn an abs_path
4212 into an absoluteURI, but it will correctly varf like Redirect
4213 if the final redirection target isn't an absoluteURI. [Ken Coar]
4215 Changes with Apache 2.0.31
4217 *) Create the scoreboard (in the parent) in a global pool context,
4218 so it survives graceful restarts. This fixes a SEGV during
4219 graceful restarts. [Aaron Bannert]
4221 *) Add a timeout option to the proxy code 'ProxyTimeout'
4224 *) FTP directory listings are now always retrieved in ASCII mode.
4225 The FTP proxy properly escapes URI's and HTML in the generated
4226 listing, and escapes the path components when talking to the FTP
4227 server. It is now possible to browse the root directory by using
4228 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
4229 Also, the last path component may contain wildcard characters
4230 '*' and '?', and if they do, a directory listing is created instead
4231 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
4234 *) Added single-listener unserialized accept support to the
4235 worker MPM [Brian Pane]
4237 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
4238 the incoming host header through to the proxied server
4239 [Geoff <g.russell ieee.org>]
4241 *) New Directive Option for ProxyPass. It now can block a location
4242 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
4244 *) Don't let the default handler try to serve a raw directory. At
4245 best you get gibberish. Much worse things can happen depending
4246 on the OS. [Jeff Trawick]
4248 *) Change the pre_config hook to return a value. Modules can now emit
4249 an error message and then cause the server to quit gracefully during
4250 startup. This required a bump to the MMN. [Aaron Bannert]
4252 *) Fix some unix socket descriptor leaks in the handler side of
4253 mod_cgid (the part that runs in the server process). Whack a
4254 silly "close(-1)" in the handler too. [Jeff Trawick]
4256 *) Change the pre_mpm hook to return a value, so that scoreboard
4257 init errors percolate up to code that knows how to exit
4258 cleanly. This required a bump to the MMN. [Jeff Trawick]
4260 *) Add the socket back to the conn_rec and remove the create_connection
4261 hook. The create_connection hook had a design flaw that did not
4262 allow creating connections based on vhost info. [Bill Stoddard]
4264 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
4265 Resolves the common case of using negotation to resolve the request
4266 /script/foo for /script.cgi/foo. [William Rowe]
4268 *) Added new functions ap_add_(input|output)_filter_handle to
4269 allow modules to bypass the usual filter name lookup when
4270 adding hard-coded filters to a request [Brian Pane]
4272 *) caching should now work on subrequests (still very experimental)
4275 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
4277 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
4280 *) Refactor ap_rgetline so that it does not use an internal brigade.
4281 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
4283 *) Remove mod_auth_db. [Justin Erenkrantz]
4285 *) Do not install unnecessary pcre headers like config.h and internal.h.
4286 [Joe Orton <joe manyfish.co.uk>]
4288 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
4289 (as it does for a normal request). quick_handled sub-requests now work
4290 in mod-include [Ian Holsman]
4292 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
4293 'CONTENT' one, as it needs to run AFTER all content headers
4295 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
4298 *) Split out blocking from the mode in the input filters.
4301 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
4303 *) Cause Win32 to capture all child-worker process errors in
4304 Apache to the main server error log, until the child can
4305 open its own error logs. [William Rowe]
4307 *) HPUX 11.*: Do not kill the child process when accept()
4308 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
4309 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
4311 *) Fix a problem in the parsing of the <Proxy foo> directive.
4314 *) rewrite of mod_ssl input filter for better performance and less
4315 memory usage [Doug MacEachern]
4317 *) allow quick_handler to be run on subrequests. [Ian Holsman]
4319 *) mod_dav now asks its provider to place content directly into the
4320 filter stack when handling a GET request. The mod_dav/provider
4321 API has changed, so providers need to be updated. [Greg Stein]
4323 *) Clear the output socket descriptor in unixd_accept() to make sure
4324 we don't supply a bogus socket to the caller if the accept fails.
4325 This caused problems with the worker MPM, which tried to process
4326 the returned socket if it was non-NULL. [Brian Pane]
4328 *) Move a check for an empty brigade to the start of core input filter
4329 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
4331 *) Add FileETag directive to allow configurable control of what
4332 data are used to form ETag values for file-based URIs. MMN
4333 bumped to 20020111 because of fields added to the end of
4334 the core_dir_config structure. [Ken Coar]
4336 *) Fix a segfault in mod_rewrite's logging code caused by passing the
4337 wrong config to ap_get_remote_host(). [Jeff Trawick]
4339 *) Allow mod_cgid to work from a binary distribution install by
4340 using 755 for the permissions on the log directory instead of
4343 *) Fixed a segfault that happened during graceful shutdown (or when
4344 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
4346 *) Split all Win32 modules [excluding the core components mod_core,
4347 mod_so, mod_win32 and the winnt mpm] into individual loadable
4348 modules, so the administrator may individually disable the former
4349 compiled-in modules by simply commenting out their LoadModule
4350 directives. [William Rowe]
4352 *) Saved Win32 module authors and porters many future headaches, by
4353 duplicating the appropriate .h files such as os.h into the include
4354 directory, including in the build tree. [William Rowe]
4356 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
4357 Use SSL functions/macros instead of directly dereferencing SSL
4358 structures wherever possible.
4359 Add type-casts for the cases where functions return a generic pointer.
4360 Add $SSL/include to configure search path.
4361 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4363 *) Moved several pointers out of the shared Scoreboard so it is
4364 more portable, and will present the vhost name across server
4365 generation restarts. [William Rowe]
4367 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
4370 Changes with Apache 2.0.30
4372 *) Fix the main bug for FreeBSD and threaded MPM's. There are
4373 still issues (see STATUS) but at least the server will now
4374 run without crashing the machine.
4375 [David Reid, Aaron Bannert, Justin Erenkrantz]
4377 *) Fix a typo in mod_deflate's m4 config section.
4378 [albert chin <china thewrittenword.com>]
4380 *) Fix a couple of mod_proxy problems forwarding HTTP connections
4381 and handling CONNECT:
4382 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
4383 (2) Proxy failed to connect when the first IP address returned by
4384 the resolver was unreachable but a secondary IP address was.
4387 *) Fix the module identifer as shown in the docs for various core
4388 modules (e.g., the identifer for mod_log_config was previously
4389 listed as config_log_module). PR #9338
4390 [James Watson <ap2bug sowega.org>]
4392 *) Fix LimitRequestBody directive by placing it in the HTTP
4393 filter. [Justin Erenkrantz]
4395 *) Fix mod_proxy seg fault when the proxied server returns
4396 an HTTP/0.9 response or a bogus status line.
4399 *) Prevent mod_proxy from truncating one character off the
4400 end of the status line returned from the proxied server.
4401 [Adam Sussman, Bill Stoddard]
4403 *) Eliminate loop in ap_proxy_string_read().
4404 [Adam Sussman, Bill Stoddard]
4406 *) Provide $0..$9 results from mod_include regex parsing.
4409 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
4411 *) Introduced the ForceLanguagePriority directive, to prevent
4412 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
4413 when using Multiviews. [William Rowe]
4415 *) Fix a problem which prevented mod_cgid and suexec from working
4416 together reliably [Greg Ames]
4418 *) Remove the call to exit() from within mod_auth_digest's post_config
4419 phase. [Aaron Bannert]
4421 *) Fix a problem in mod_auth_digest that could potentially cause
4422 problems with initialized static data on a system that uses DSOs.
4425 *) Fix a segfault in the worker MPM that could happen during
4426 child process exits. [Brian Pane, Aaron Bannert]
4428 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
4430 *) Fix matching of vhosts by ip address so we find IPv4
4431 vhost address when target address is v4-mapped form of
4432 that address. [Jeff Trawick]
4434 *) More performance tweaks to the BNDM string-search algorithm
4435 used to find "<!--#" tokens in mod_include [Brian Pane]
4437 *) Miscellaneous small performance fixes: optimized away various
4438 string copy operations and removed large temp buffers from
4439 the stack [Brian Pane]
4441 *) Fixed startup segfault that occurred when a VirtualHost
4442 directive had a port but no address [Brian Pane]
4444 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
4446 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
4447 if oslevel < WINNT. This should fix several problems reported
4448 Against 2.0.28 on Windows 98 [Bill Stoddard]
4450 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
4451 to fail. [Bill Stoddard]
4453 *) Change core code to allow an MPM to set hard thread/server
4454 limits at startup. prefork, worker, and perchild MPMs now have
4455 directives to set these limits. [Jeff Trawick]
4457 *) Win32: The async AcceptEx() event should be autoreset upon
4458 successful completion of a wait (WaitForSingleObject). This
4459 eliminates a number of spurious
4460 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
4463 *) Move any load library path environment variables out of
4464 apachectl and into a separate environment variable file which
4465 can be more easily tailored by the admin. The environment
4466 variable file as built by Apache may have additional system-
4467 specific settings. For example, on OS/390 we tailor the heap
4468 settings to allow lots of threads. [Jeff Trawick]
4470 *) Use the new APR pool code to reduce pool-related lock
4471 contention in the worker MPM. [Sander Striker]
4473 *) The POD no longer assumes the child is listening on 127.0.0.1
4474 and now pulls the first hostname in the list of listeners to
4475 perform the dummy connect on. This fixes a bug when the user
4476 had configured the Listen directive for an IP other than
4477 127.0.0.1. This would result in undead children and error
4478 messages such as "Connection refused: connect to listener".
4481 *) The worker MPM now respects the LockFile setting, needed to
4482 avoid locking problems with NFS. [Jeff Trawick]
4484 *) Fix segfault when worker MPM receives SIGHUP.
4485 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
4487 *) Fix bug that could potentially prevent the perchild MPM from
4488 working with more than one vhost/uid. [Aaron Bannert]
4490 *) Change make install and apxs -i processing of DSO modules to
4491 perform special handling on platforms where libtool doesn't install
4492 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
4493 which prevented standard LoadModule statements from working.
4496 *) Whenever mod_so is enabled (not just when there are DSOs for
4497 our modules), do whatever special magic is required for compiling/
4498 loading third-party modules. This allows third-party DSOs to
4499 be used on an AIX build when there were no built-in modules
4500 built as DSOs. (This should help on OS/390 and BeOS as well.)
4503 *) Allow apxs to be used to build DSOs on AIX without requiring the
4504 user to hard-code the list of import files. (This should help
4505 on OS/390 and BeOS as well.) [Jeff Trawick]
4507 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.

4510 *) Get binary builds working when libapr and libaprutil are built
4513 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
4514 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
4515 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
4517 *) Fix the handling of SSI directives in which the ">" of the
4518 terminating "-->" is the last byte in a file [Brian Pane]
4520 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
4521 message that we had back in apache-1.3 and still have scattered
4522 throughout our docs. [Aaron Bannert]
4524 *) Prevent the Win32 port from continuing after encountering an
4525 error in the command line args to apache. [William Rowe]
4527 *) On a error in the proxy, make it write a line to the error log
4530 *) Various mod_ssl performance improvements [Doug MacEachern]
4532 Changes with Apache 2.0.29
4534 *) Add buffering in core_output_filter to ensure that long
4535 lists of small buckets don't cause small packet writes.
4536 [Brian Pane, Ryan Bloom]
4538 *) Fix the installation target to make sure that the manual is
4539 installed in the correct location.
4540 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
4541 Gomez Henri <hgomez slib.fr>]
4543 *) Fix the cmd command for mod_include. When we are processing
4544 a cmd command, we do not want to use the r->filename to set
4545 the command name. The command comes from the SSI tag. To do this,
4546 I added a variable to the function that builds the command line
4547 in mod_cgi. This allows the include_cmd function to specify
4548 the command line itself. [Ryan Bloom]
4550 *) Change open_logs hook to return a value, allowing you
4551 to flag a error while opening logs
4552 [Ian Holsman, Doug MacEachern]
4554 *) Change post_config hook to return a value, allowing you
4555 to flag a error post config
4556 [Ian Holsman, Jeff Trawick]
4558 *) Allow SUEXEC_BIN (the path to the suexec binary that is
4559 hard-coded into the server) to be specified to the configure
4560 script by the --with-suexec-bin parameter. [Aaron Bannert]
4562 *) Fix segv in worker MPM following accept on pipe-of-death
4565 *) Add mod_deflate to experimental.

4584 *) The threaded MPM for Unix has been removed. Use the worker
4585 MPM instead. [various]
4587 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
4588 in logging the error from a failed DNS lookup. [Jeff Trawick]
4590 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
4593 *) Get mod_cgid killed when a MPM exits due to a fatal error.
4596 *) Fix a file descriptor leak in mod_include. When we include a
4597 file, we use a sub-request, but we didn't destroy the sub-request
4598 immediately, instead we waited until the original request was
4599 done. This patch closes the sub-request as soon as the data is
4600 done being generated. [Brian Pane <bpane pacbell.net>]
4602 *) Allow modules that add sockets to the ap_listeners list to
4603 define the function that should be used to accept on that
4604 socket. Each MPM can define their own function to use for
4605 the accept function with the MPM_ACCEPT_FUNC macro. This
4606 also abstracts out all of the Unix accept error handling
4607 logic, which has become out of synch across Unix MPMs.
4610 *) Fix a bug which would cause the response headers to be omitted
4611 when sending a negotiated ErrorDocument because the required
4612 filters were attached to the wrong request_rec.
4613 [John Sterling <sterling covalent.net>]
4615 *) Remove commas from the end of the macros that define
4616 directives that are used by MPMs. Prior to this patch,
4617 you would use these macros without commas, which was unlike
4618 the macros for any other directives. Now, the caller provides
4619 the comma rather than the macro providing it. This makes
4620 the macros look more like the rest of the directives.
4621 [Ryan Bloom and Cliff Woolley]
4623 *) Add 'redirect-carefully' environment option to disable sending
4624 redirects under special circumstances. This is helpful for
4625 Microsoft's WebFolders when accessing a directory resource via
4626 DAV methods. [Justin Erenkrantz]
4628 *) Begin to abstract out the underlying transport layer.
4629 The first step is to remove the socket from the conn_rec,
4630 the server now lives in a context that is passed to the
4631 core's input and output filters. This forces us to be very
4632 careful when adding calls that use the socket directly,
4633 because the socket isn't available in most locations.
4636 *) Really reset the MaxClients value in worker and threaded
4637 when the configured value is not a multiple of the number
4638 of threads per child. We said we did previously but we
4639 forgot to. [Jeff Trawick]
4641 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
4643 *) If shared modules are requested and mod_so is not available,
4644 produce a fatal config-time error. [Justin Erenkrantz]
4646 *) Improve http2env's performance by cutting the work it has to
4647 do. [Brian Pane <bpane pacbell.net>]
4649 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
4650 [Brian Pane <bpane pacbell.net>]
4652 Changes with Apache 2.0.28
4654 *) Fix infinite loop in mod_cgid.c.
4655 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
4657 *) When no port is given in a "ServerName host" directive, the
4658 server_rec->port is now set to zero, not 80. That allows for
4659 run-time deduction of the correct server port (depending on
4660 SSL/plain, and depending also on the current setting of
4661 UseCanonicalName). This change makes redirections
4662 work, even with https:// connections. As in Apache-1.3, the
4663 connection's actual port number is never used, only the ServerName
4664 setting or the client's Host: setting. Documentation updated
4665 to reflect the change. [Martin Kraemer]
4667 *) Add a '%{note-name}e' argument to mod-headers, which works in
4668 the same way as mod_log_confg. [Ian Holsman]
4670 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
4671 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
4672 MPMs. [Cliff Woolley]
4674 *) Introduce htdbm, a user management utility for db/dbm authorization
4675 databases. [Mladen Turk <mturk mappingsoft.com>]
4677 *) Optimize usage of strlen and strcat in ap_directory_walk.
4678 [Brian Pane <bpane pacbell.net>]
4680 Changes with Apache 2.0.27
4682 *) Introduce an Apache mod_ssl initial configuration template
4683 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
4685 *) Fixed a memory leak in the getline parsing code that could
4686 be triggered by arbitrarily large header lines. Requests
4687 from the core input filter for single lines are now limited
4688 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
4690 *) Fix a truncation bug in how we print the port on the Via: header.
4691 The routine that prints the Via: header now takes a length for
4692 the port string. [Zvi Har'El <rl math.technion.ac.il>]
4694 *) Some syntax errors in mod_mime_magic's magic file can result
4695 in a 500 error, which previously was unlogged. Now we log the
4696 error. [Jeff Trawick]
4698 *) Add the support/checkgid helper app, which checks the run-time
4699 validity of group identifiers usable in the Group directive.
4702 *) Various --enable-so options have been fixed: --enable-so is
4703 treated as "static"; explicit --enable-so=shared issues an error;
4704 and explicit --enable-so fails with error on systems without
4705 APR_HAS_DSO. [Aaron Bannert]
4707 *) Fix a segfault in the core input filter when the client socket
4708 gets disconnected unexpectedly. [Cliff Woolley]
4710 *) Fix the reporting for child processes that die. This removes
4711 all of the non-portable W* macros from Apache.
4712 [Jeff Trawick and Ryan Bloom]
4714 *) Win32: Track and display "Parent Server Generation:" in
4715 mod_status output. The generation will be bumped at
4716 server graceful restart, when the child process exits
4717 by hitting MaxRequestsPerChild or if the child
4718 process exits abnormally. [Bill Stoddard]
4720 *) Win32: Fix problem where MaxRequestsPerChild directive was
4721 not being picked up in favor of the default. Enable
4722 the parent to start up a new child process immediately upon
4723 the old child starting shutdown.
4726 *) Fix some bungling of the remote port in rfc1413.c so that
4727 IdentityCheck retrieves the proper user id instead of failing
4728 and thus always returning "nobody."
4729 [Dick Streefland <Dick.Streefland xs4all.nl>]
4731 *) Introduced thread saftey for mod_rewrite's internal cache.
4732 [Brian Pane <bpane pacbell.net>]
4734 *) Simplified mod_env's directives to behave as most directives are
4735 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
4736 directive following that UnsetEnv within the same container.
4737 Also provides a runtime startup warning if a PassEnv configured
4738 environment value is undefined. [William Rowe]
4740 *) The worker MPM is now completely ported to APR's new lock API. It
4741 uses native APR types for thread mutexes, cross-process mutexes,
4742 and condition variables. [Aaron Bannert]
4744 *) Sync up documentation to remove all references to the now deprecated
4745 Port directive. [Justin Erenkrantz]
4747 *) Moved all ldap modules from the core to httpd-ldap sub-project
4750 *) Exit when we can't listen on any of the configured ports. This
4751 is the same behavior as 1.3, and it avoids having the MPMs to
4752 deal with bogus ap_listen_rec structures. [Jeff Trawick]
4754 *) Cleanup the proxy code that creates a request to the origin
4755 server. This change adds an optional hook, which allows modules
4756 to gain control while the request is created if the proxy module
4757 is loaded. The purpose of this hook is to allow modules to add
4758 input and/or output filters to the request to the origin. While
4759 I was at it, I made the core use this hook, so that proxy request
4760 creation uses some of the code from the core. This can still be
4761 greatly improved, but this is a good start. [Ryan Bloom]
4763 Changes with Apache 2.0.26
4765 *) Port the MaxClients changes from the worker MPM to the threaded
4768 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
4769 with the new input filtering system. [Justin Erenkrantz]
4771 *) Introduce the MultiviewsMatch directive, to allow the operator
4772 to be flexible in recognizing Handlers and Filters filename
4773 extensions as part of the Multiviews matching logic, strict with
4774 MultiviewsMatch NegotiatedOnly to accept only filename extentions
4775 that designate negotiated parameters, (content type, charset, etc.)
4776 or MultiviewsAll for the 1.3 behavior of matching any files, even
4777 if they have unregistered extensions. [William Rowe]
4779 *) Fixed the configure script to add a LoadModule directive to
4780 the default httpd.conf for any module that was compiled
4781 as a DSO. [Aaron Bannert <aaron clove.org>]
4783 *) rewrite mod_ssl input filtering to work with the new input filtering
4784 system. [Justin Erenkrantz]
4786 *) prefork: Don't segfault when we are able to listen on some but
4787 not all of the configured ports. [Jeff Trawick]
4789 *) Build mod_so even if no core modules are built shared.
4790 [Aaron Bannert <aaron clove.org>]
4792 *) Introduce ap_directory_walk rewrite (with further optimizations
4793 required) to adapt to the ap_process_request_internal() changes.
4794 Optimized so subrequests and redirects now reuse previous section
4795 merges, until we mismatch with the original directory_walk, and
4796 precomputed r->finfo results will cause directory_walk to skip
4797 the most expensive phases of the function. [William Rowe]
4799 *) Allow ApacheMonitor to connect to and control Apache on other
4800 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
4802 *) Remove the Port directive. In it's place, the Listen directive
4803 is now a required directive, which tells Apache what port to
4804 listen on. The ServerName directive has also been extended
4805 to accept an optional port. If the port is specified to the
4806 ServerName, the server will report that port whenever it
4807 reports the port that it is listening on. This change was
4808 made to ease configuration errors that stem from having a Port
4809 directive, and a Listen directive. In that situation, the server
4810 would only listen to the port specified by the Listen command,
4811 which caused a lot of confusion to users. [Ryan Bloom]
4813 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
4814 build, as loadable modules. [William Rowe]
4816 *) Fix --enable-mods-shared processing. If most is specified,
4817 then all modules that can be compiled as shared modules are.
4818 [Aaron Bannert <aaron clove.org>]
4820 *) Update the mime.types file to map video/vnd.mpegurl to mxu
4821 and add commonly used audio/x-mpegurl for m3u extensions.
4822 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
4824 *) Eliminate the depreciated r->content_language, in favor of the array
4825 r->content_languages introduced many years ago. Module authors must
4826 substantially overhaul their modules, so this needs to be upgraded
4827 if the module still relied on backwards-brokeness. [William Rowe]
4829 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
4832 *) Rewrite the input filtering mechanisms to consolidate and reorganize
4833 code. In short, core_input_filter does something now and
4834 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
4836 *) Update the Win32 build to re-absorb mod_proxy and family.
4839 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
4840 current SDK.) [William Rowe]
4842 *) Some style changes to the code that does ProxyErrorOverride. Fixed
4843 config merge behaviour. [Graham Leggett]
4845 *) Allow support programs to be compiled against a static version
4846 of libapr. This allows the smaller support programs to be
4847 relocated. [Aaron Bannert <aaron clove.org>]
4849 *) Update the mime.types file to the registered media types as
4850 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
4852 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
4853 number of clients that can connect at the same time, instead of
4854 specifying the maximum number of child processes.
4855 [Aaron Bannert <aaron clove.org>]
4857 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
4858 be consistent with 1.3. [Justin Erenkrantz]
4860 *) Cache apr_explode_localtime() value for 15 seconds.
4861 [Brian Pane <bpane pacbell.net>]
4863 *) Fix mod_include to not return ETag or Last-Modified headers.
4864 [Ian Holsman <ianh cnet.com>]
4866 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
4868 *) Eliminate the wasteful run-time conversion of method names from strings
4869 to numbers in places where the methods are known at compile time.
4870 [Brian Pane <bpane pacbell.net>]
4872 *) Turn the worker MPM's queue into a LIFO. This may
4873 improve cache-hit performance under some conditions.
4874 [Aaron Bannert <aaron clove.org>]
4876 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
4877 support it. [Justin Erenkrantz]
4879 *) Cleanup the worker MPM. We no longer re-use transaction
4880 pools. This incurs less overhead than shuffling the pools
4881 around so that they can be re-used. Remove one of the
4882 queue's condition variables. We just redefined the API to
4883 state that you can't try to add more stuff than you allocated
4884 segments for. [Aaron Bannert <aaron clove.org>]
4886 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
4888 *) Fixed persistent connections when a request contains a body.
4891 *) mod_dav uses a new API to speak to the backend provider for dead
4892 property management. [Greg Stein]
4894 *) Remove the Win32 script-processing exception from mod_cgi, and
4895 roll build_command_line/build_argv_list into a unified, overrideable
4896 ap_cgi_build_command optional function. [William Rowe]
4898 *) Rewrite find_start_sequence to use a better search algorithm
4899 to find the start tag. [Justin Erenkrantz]
4901 *) Fix a seg fault in mod_include. When we are generating an
4902 internal redirect, we must set r->uri to "", not a bogus
4903 string, and not NULL. [Ryan Bloom]
4905 *) Optimized location_walk, so subrequests, redirects and second passes
4906 now reuse previous section merges on a <Location > by <Location >
4907 basis, until we mismatch with the original location_walk.
4910 *) Back out the 1.45 change to util_script.c. This change made
4911 us set the environment variable REQUEST_URI to the redirected
4912 URI, instead of the originally requested URI.
4913 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4915 *) Make mod_include do lazy evaluation of potentially expensive to
4916 compute variables. [Brian Pane <bpane pacbell.net>]
4918 *) Fix logging of bytes sent for HEAD requests. %b and %B should
4919 log either - or 0, before this patch, they were both logging
4920 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
4922 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
4923 than per character. [Brian Pane <bpane pacbell.net>]
4925 *) Normalize the primary request, redirects and sub-requests to
4926 run the same ap_process_request_internal for consistency in
4927 robustness, behavior and security. [William Rowe]
4929 *) Fix a segfault with mod_include when r->path_info is not set
4930 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
4932 *) Add -X functionality back. This indicates to all MPMs and any other
4933 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
4935 *) Some initial support for the cygwin platform [prefork only].
4936 This is not to be confused with support for the WinNT/Win32
4937 platform, which is the recommended configuration for native
4938 Win32 users. The cygwin platform support is recommended for
4939 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
4941 *) Changed syntax of Set{Input|Output}Filter. The list of filters
4942 must be semicolon delimited (if more than one filter is given.)
4943 The Set{Input|Output}Filter directive now overrides a parent
4944 container's directive (e.g. SetInputFilter in <Directory /web/foo>
4945 will override any SetInputFilter directive in <Directory /web>.)
4946 This new syntax is more consistent with Add{Input|Output}Filter
4947 directives defined in mod_mime. Also cures a bug in prior releases
4948 where the Set{Input|Output}Filter directive would corrupt the
4949 global configuration if the multiple directives were nested.
4952 *) Cured what's ailed mime for quite some time. If an AddSomething
4953 was given in the configuration (Language, Charset, Handler or
4954 Encoding) Apache would set the content type as given by AddType,
4955 but refused to check the mime.types file if AddType wasn't given
4956 for that specific extension. Setting the AddHandler for .html
4957 without setting the AddType text/html html would cause Apache to
4958 use the default content type. [William Rowe]
4960 *) Added some bulletproofing to memory allocation in the LDAP cache
4961 code. [Graham Leggett]
4963 Changes with Apache 2.0.25
4965 *) Move the installed /manual directory out of the /htdocs/ tree, so
4966 that it can be kept more independently from the remaining document
4967 root. The "Alias /manual ..." already allowed for easy projection
4968 into existing private document trees. [Martin Kraemer]
4970 *) Add specified user attributes to the environment when using
4971 mod_auth_ldap. This allows you to use mod_include to embed specified
4972 user attributes in a page like so:
4973 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
4976 *) Fix a performance problem with the worker MPM. We now create
4977 transaction pools once, and re-use them for each connection.
4978 [Aaron Bannert <aaron clove.org>]
4980 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
4981 of a 'handler' or 'filter', so that any filename extension that does
4982 not contribute to the negotiated metadata can't be served without
4983 an explicit request. E.g., if the .Z extension is associated with
4984 an unzip filter, the user request somefile.Z.html, mod_negotiation
4985 won't serve it. It can serve somefile.Z.html when somefile.Z is
4986 requested, since the .Z extension is explictly requested, if the
4987 .html extension is associated with ContentType text/html.
4990 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
4991 and corresponding AddOutputFilter syntax, to insert one or more
4992 filters by mod_mime filename extension processing.
4995 *) Fix a growing connection pool in core_output_filter() for
4996 keepalive requests. [Jeff Trawick]
4998 *) Moved split_and_pass_pretag_buckets back to being a
4999 macro at Ryans's request. Removed the return from it
5000 by setting and returning a return code instead. Updated
5001 the code to check the return code from the macro and
5002 do the right thing. [Paul J. Reder]
5004 *) Fix a segfault when a numeric value was received for Host:.
5007 *) Add a function ap_remove_input_filter. This is to match
5008 up with ap_remove_output_filter. [Ryan Bloom]
5010 *) Clean up location_walk, so that this step performs a minimum
5011 amount of redundant effort (it must be run twice, but it will no
5012 longer reparse all <Location > blocks when the request uri
5013 hadn't changed.) [William Rowe]
5015 *) Eliminate proxy: (and all other 'special') processing from the
5016 ap_directory_walk() phase. Modules that want to use special
5017 walk logic should refer to the mod_proxy map_to_location example,
5018 with it's proxy_walk and proxysection implementation. This makes
5019 either directory_walk flavor much more legible, since that phase
5020 only runs against real <Directory > blocks.
5023 *) SECURITY: Fix a security problem in mod_include which would allow
5024 an SSI document to be passed to the client unparsed.
5025 [Cliff Woolley, Brian Pane]
5027 *) Introduce the map_to_storage hook, which allows modules to bypass
5028 the directory_walk and file_walk for non-file requests. TRACE
5029 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
5030 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
5033 *) Add the ability for mod_include to add the INCLUDES filter
5034 if the file is configured for the server-parsed handler.
5035 This makes the configuration for .shtml files much easier
5036 to understand, and allows mod_include to honor Apache 1.3
5037 config files. Based on Doug MacEachern's patch to PHP
5038 to do the same thing. [Ryan Bloom]
5040 *) force OpenSSL to ignore process local-caching and to always
5041 get/set/delete sessions using mod_ssl's callbacks
5042 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
5043 Geoff Thorpe <geoff geoffthorpe.net>]
5045 *) Make the worker MPM shutdown and restart cleanly. This also
5046 cleans up some race conditions, and gets the worker using
5047 pools more cleanly. [Aaron Bannert <aaron clove.org>]
5049 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
5051 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
5053 *) Fix for mod_include. Ryan's patch to check error
5054 codes put a return in the wrong place. Also, the
5055 include handler return code wasn't being checked.
5056 I don't like macros with returns, so I converted
5057 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
5058 [Paul J. Reder <rederpj raleigh.ibm.com>]
5060 *) fix segv in mod_mime if no AddTypes are configured
5061 [John Sterling <sterling covalent.net>]
5063 *) Enable ssl client authentication at SSL_accept time
5064 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
5066 *) Fix a segfault in mod_include when the original request has no
5067 associated filename (e.g., we're filtering the error document for
5068 a bad URI). [Jeff Trawick]
5070 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
5072 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
5073 of httpd is started and shuts down due to socket conflict. Moving the
5074 call to ap_log_pid solves the problem.
5076 *) Changed the late-1.3 log_config substitution %c to %X, to log the
5077 status of the closed connection, as it conflicts with the far more
5078 common, historical ssl logging directive %...{var}c. [William Rowe]
5080 *) Added the common error/ tree to the build/install targets
5081 (similar to the common icons/ tree) for the multi-language error
5082 messages that Lars committed earlier. [William Rowe]
5084 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
5086 *) Added a default commented-out mod_ldap and mod_auth_ldap
5087 configuration to httpd-std.conf and httpd-win.conf
5090 *) Added documentation for mod_ldap and mod_auth_ldap.
5093 *) Enabled negative caching on attribute comparisons in the LDAP cache.
5094 Fixed a problem where the default cache TTL was set in milliseconds
5095 not microseconds causing the cache to time out almost immediately.
5098 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
5099 module code to follow APR. [Graham Leggett]
5101 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
5102 cleaned up when the connection pool pool is cleaned up.
5105 *) Fix a minor issue with Jeff Trawick's mod_include
5106 patch. Without this patch, the code will just allocate
5107 more bytes in get_combined_directive than are needed.
5110 *) Added the LDAP authentication module mod_auth_ldap.
5111 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
5113 *) Added the LDAP cache and connection pooling module mod_ldap.
5114 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
5116 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
5117 by allowing a module to disable itself if its prerequisites are not
5118 met. [Justin Erenkrantz]
5120 Changes with Apache 2.0.24
5122 *) Fix a couple of issues in mod_include when the tag appeared at
5123 offsets near 8192 in the file being parsed. [Jeff Trawick]
5125 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
5126 reached. [Jeff Trawick]
5128 *) Numerous improvements to the Win32 build system. Introduced command line
5129 builds without requiring .mak files for MSVC 6.0 and later versions.
5130 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
5133 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
5134 reporting of uninstalled services and other error conditions, and changed the
5135 default service name to Apache2. [William Rowe]
5137 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
5138 compatibility with existing Apache 1.3 Win32 Apache management utilites.
5139 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
5141 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
5142 [William Rowe, Greg Ames]
5144 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
5145 and RemoveCharset directives. [William Rowe]
5147 *) The Unix MPMs other than perchild now allow child server
5148 processes to use the accept mutex when starting as root and
5149 using SysV sems for the accept mutex. Previously, this
5150 combination would lead to fatal errors in the child server
5151 processes. perchild can't use SysV sems because of security
5152 issues. [Jeff Trawick, Greg Ames]
5154 *) Added Win32 revision stamp resources to all http binaries
5155 (including modules/ and support/ tools.) PR7322 [William Rowe]
5157 *) Fix ap_rvprintf to support more than 4K of data at one time.
5158 [Cody Sherr <csherr covalent.net>]
5160 *) We have always used the obsolete/deprecated Netscape syntax
5161 for our tracking cookies; now the CookieStyle directive
5162 allows the Webmaster to choose the Netscape, RFC2109, or
5163 RFC2965 format. The new CookieDomain directive allows the
5164 setting of the cookie's Domain= attribute, too. PR #s 5006,
5165 5023, 5920, 6140 [Ken Coar]
5167 *) Tweak server/Makefile so that the rules for generating exports.c
5168 are compatible with make utilities which don't expand wildcards
5169 in a dependency list (e.g., OS/390 make, certain levels of GNU
5170 make). [Jeff Trawick]
5172 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
5174 *) Begin to sanitize the MPM configuration directives. Now, all
5175 MPMs use the same functions for all common MPM directives. This
5176 should make it easier to catch all bugs in these directives once.
5177 [Cody Sherr <csherr covalent.net>]
5179 *) Close a major resource leak. Every time we had issued a
5180 graceful restart, we leaked a socket descriptor.
5183 *) Fix a problem with the new method code. We need to cast
5184 the 1 to an apr_int64_t or it will be treated as a 32-bit
5185 integer, and it will wrap after being shifted 32 times.
5186 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
5188 *) Fix a bug in mod_expires. Previous to this patch, if you
5189 told mod_expires to add 604800 seconds to the last-modified
5190 time, it actually added 604800 usec's to the last-modified time,
5191 so that when looking at the response it looked like nothing
5192 had been done. The root of the problem was that we always compute
5193 time in usec's, but we ask users to input sec's. This means we
5194 need to convert to usec's before using those values.
5197 *) The worker MPM now handles shutdown and restart requests. It
5198 definitely isn't perfect, but we do stop the servers correctly.
5199 The biggest problem right now is that SIGHUP causes the server to
5200 just die. [Ryan Bloom]
5202 Changes with Apache 2.0.23
5204 *) Use the prefork MPM by default on Unix. [various]
5206 *) Added a systray icon monitor application for Win32.
5207 [Mladen Turk <mturk mappingsoft.com>]
5209 *) mod_rewrite: Fix the line ending on some non-Unix systems for
5210 messages written to the rewrite log.
5211 [Richard Labennett <rlabenn us.ibm.com>]
5213 *) All mod_autoindex query parsing is now quietly quashed with the
5214 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
5215 still drops the column sort <a href>'s for the column headers, but
5216 IgnoreClient is required to ignore these Query options entirely.
5219 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
5220 to allow the client to select plain, FancyIndexing or HTMLTable
5221 formatting, V=[0|1] to inhibit or enable version sorting, and
5222 P=pattern to return only specific files. The old Query Arguments
5223 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
5224 as before), and O=A|D for ordering ascending or descending.
5227 *) Fixed an error in mod_include's directive parsing routines which
5228 caused #if, #elif, and #else expressions containing backslashes
5229 to be improperly evaluated. [Cliff Woolley]
5231 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
5232 drop the icon column, SuppressRules to drop the <hr> elements,
5233 and HTMLTable to create rudimentary HTML table listings (implies
5234 FancyIndexing). [William Rowe]
5236 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
5237 from Apache 1.3.15. This is needed for two reasons, first, given
5238 multiple machines within a server farm, ETags and Last-Modified
5239 stamps won't correspond from machine to machine, and second, many
5240 Unixes don't capture changes to the date or time stamp of existing
5241 files, since these don't modify the dirent itself. [William Rowe]
5243 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
5244 and DirectoryWidth options from Apache 1.3.10.
5245 [William Rowe, Ken Coar]
5247 *) Eliminated FancyIndexing directive, deprecated early in Apache
5248 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
5250 *) mod_autoindex now excludes any file names that would result in
5251 an error, other than a success or redirect. Also optimized
5252 the parent directory, always included except in the URI '/'.
5255 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
5256 negotiated index pages, and prevent the server from defaulting
5257 to an autoindex of the directory. mod_negotiation will now die
5258 with a 500 Internal Error if it could match some filenames
5259 (e.g. for mod_dir) but none can be served. mod_negotation now
5260 refuses to serve any file with an extention that mod_mime doesn't
5261 recognize, and wasn't part of the request. [William Rowe]
5263 *) Eliminate mod_cgi's handling of .exe files without the .exe file
5264 extension. This is already handled by multiviews, if the admin
5265 wishes to AddHandler .exe or define a content type handler and
5266 associate .exe files with that content type. Multiviews must be
5267 enabled to allow these to be served. [William Rowe]
5269 *) Speed up the server's response to a spike in incoming workload
5270 or restarts by assigning empty scoreboard slots to new processes
5271 when they are available. [Greg Ames]
5273 *) Add a handler to mod_includes.c. This handler is designed to
5274 implement the XbitHack directive. This can't be done with a
5275 fixup, because we need to check the content-type, which is
5276 only available in the handler phase. [Ryan Bloom]
5278 *) Make the includes filter check return codes from filters lower in
5279 the filter chain. If a lower level filter returns an error, then
5280 the request needs to stop immediately. This allows mod_include to
5281 stop parsing data once a lower filter recognizes an error.
5284 *) Add the ability to extend the methods that Apache understands
5285 and have those methods <limit>able in the httpd.conf. It uses
5286 the same bit mask/shifted offset as the original HTTP methods
5287 such as M_GET or M_POST, but expands the total bits from an int to
5288 an ap_int64_t to handle more bits for new request methods than
5289 an int provides. [Cody Sherr <csherr covalent.net>]
5291 *) Fix broken mod_mime behavior in merging its arguments. Possible
5292 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
5294 *) Solve many mod_ssl porting issues (too many to detail) with
5295 help from the whole team, but most notably [Ralf S. Engelschall,
5296 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
5297 Doug MacEachern, William Rowe, Cliff Woolley]
5299 *) More stall fixes for the threaded & worker mpm's.
5300 Make mod_status output more accurate. Don't
5301 count workers in processes which aren't actively
5302 serving requests. [Greg Ames]
5304 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
5306 *) Add a single listener/multiple worker MPM. This MPM is
5307 definately not fully correct, but it allows us to solve many
5308 of the problems that exist in the threaded MPM. This is a
5309 modified version of the threaded MPM. [Ryan Bloom]
5311 *) Improve content generation throughout Apache, providing closer
5312 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
5313 Transitional specifications. [William Rowe]
5315 Changes with Apache 2.0.22
5317 *) Fix a problem where the threaded MPM stalls after restarts or
5318 segfaults. Also prevent multiple active processes from using
5319 the same scoreboard slot. [Greg Ames]
5321 *) Apache/Win32 now fills in the service description with Apache's
5322 server version string, including loaded and advertised modules.
5325 *) Improved support for the Win32 build, to recover gracefully from
5326 missing apr or apr-util directories or the awk interpreter,
5327 create the proper cgi-bin examples, including a test-cgi.bat, and
5328 fix the perl shebang line for printenv.pl, when installing from
5329 the build environment. [William Rowe]
5331 *) Fix a segfault in threaded.c caused by passing uninitialized
5332 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
5334 *) Use new APR number conversion functions to reduce CPU consumption
5335 when setting the content length, and in mod_log_config.
5338 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
5339 where HEAD response headers were being repeated twice for
5340 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
5341 problem in the http_header filter was exposed by the recent rewrite
5342 of the content_length filter. [Taketo Kabe, Bill Stoddard]
5344 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
5345 restarts. A garbage pointer to a vhost's server_rec from the
5346 previous generation was being left around under certain
5347 conditions. [Greg Ames]
5349 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
5350 used to appear as '(none', without the closing paren.
5351 [Günter Knauf <eflash gmx.net>]
5353 *) Improve the exports generating awk script. In the past, we had
5354 work around problems in the awk script by avoiding some #if and
5355 #ifdefs. This has bitten us many times in generating the exports.c
5356 file. This improvement allows corrects the header file parsing.
5357 [Sander Striker <striker apache.org>]
5359 Changes with Apache 2.0.21
5361 *) Resolve the Win32 htpasswd bug, where a file that existed would be
5362 overwritten, regardless of the -c flag.
5363 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
5365 *) Introduce connection sub-pools into ab. Truncating the lifetime
5366 of these allocations means that ab no longer perpetually grows
5367 its working set, running out of memory on large request attempts.
5370 *) Make scoreboard creation a hook. This allows management
5371 modules to have access to the scoreboard at the time that it is
5372 created, and at every restart request.
5373 [Cody Sherr <csherr covalent.net>]
5375 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
5376 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
5377 daemon index actually used in the scoreboard. I also
5378 updated the pertinent calls. [Paul J. Reder]
5380 *) Win32: Prevent listening sockets from being inherited by
5381 the Apache child process, CGI scripts, rotatelog process
5382 etc. If the Apache child process segfaults, any processes
5383 that the child started are not reaped. Prior to this fix,
5384 these processes inherited the listening sockets which sometimes
5385 prevented the restarted Apache child process from accepting
5386 connections (ie, the server would hang).
5389 *) Provide vhost and request strings when ExtendedStatus is on.
5392 *) Fix some issues with the pod and prefork: check the pod *after*
5393 processing a connection so that a server processing a time-
5394 consuming request bails out as soon as practical; when the
5395 parent process wakes up a server process via connect(), use an
5396 APR timeout on the connect() so that we don't hang for a long
5397 time if there aren't server processes around to do accept().
5398 [Jeff Trawick, Greg Ames]
5400 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
5401 spends a lot of time in apr_table_get calls. Using the default
5402 httpd.conf, the tables for languages and charsets are somewhat
5403 large, so the time spent scanning them on each request is
5404 significant. Replacing the tables with hash tables provides
5405 a nice speedup. [Brian Pane <bpane pacbell.net>]
5407 *) Add two functions to allow modules to access random parts of the
5408 scoreboard. This allows modules compiled for one MPM to access the
5409 scoreboard, even if it the server was compiled for another MPM.
5410 [Harrie Hazewinkel <harrie covalent.net>]
5412 Changes with Apache 2.0.20
5414 *) Fix problem in content-length filter where the filter would
5415 buffer all the output from a CGI before sending any bytes
5416 down the filter stack to the network. This problem would cause
5417 significant memory consumption if the CGIs generated
5418 lots of bytes. [Bill Stoddard]
5420 *) Get non-blocking CGI pipe reads working with the bucket brigades.
5423 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
5426 *) Fix a bug in the threaded MPM that would cause it to kill off all
5427 workers immediately after starting if the number of workers started
5428 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
5430 Changes with Apache 2.0.19
5432 *) Fix problem with threaded MPM. The problem was that if each child
5433 process was busy serving a single long-lived request and the server
5434 was sent a graceful restart signal, the server would stop serving
5435 requests. This would happen because each child process would wait to
5436 die until the last thread was done, and the parent wouldn't spawn any
5437 new children until a process died. Now, the parent looks at the fact
5438 that the children are dying gracefully, and starts new children.
5439 Those new children only start enough threads to compliment the number
5440 of threads in the other child process that shares the same spot in
5441 the scoreboard. In this way, we make sure to never go over
5442 MaxClients. [Ryan Bloom]
5444 *) modified mod_negotiation and mod_autoindex to speed up by almost a
5445 factor of two on apr_dir_read()-enhanced platforms, such as Win32
5446 and OS2, by calling ap_sub_request_lookup_dirent() with the results
5447 already provided by apr_dir_read(). [William Rowe]
5449 *) mod_file_cache is now more robust to filtering and serves requests
5450 slightly more efficiently. [Cliff Woolley]
5452 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
5453 Module was calling ap_rwrite() followed by ap_rflush() but the
5454 served content was not being displayed in the browser. Inspection
5455 of the output stream revealed that the first data chunk was
5456 missing the trailing CRLF required by the RFC. [Bill Stoddard]
5458 *) apxs no longer generates ap_send_http_header() in the example handler
5460 *) Fix an ab problem which could cause a divide-by-zero exception
5461 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
5462 [Ian Holsman <ianh cnet.com>]
5464 *) Solve case-insensitive platforms' confusion about negotiated
5465 filenames, allowing files of differnt case to match in choosing
5466 the document to serve. [William Rowe]
5468 *) Fix brokenness when ThreadsPerChild is higher than the built-in
5469 limit. We left ap_threads_per_child at the higher value which
5470 led to segfaults when doing certain scoreboard operations.
5473 *) Fix seg faults and/or missing output from mod_include. The
5474 default_handler was using the subrequest pool for files and
5475 MMAPs, even though the associated APR structures typically
5476 live longer than the subrequest. [Greg Ames]
5478 *) Extend mod_setenvif to support specifying regular expressions
5479 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
5480 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
5481 will cause HAVE_TS to be set if any of the request headers begins
5482 with "TS" and has a value that begins with any character in the
5483 set [a-z]. [Bill Stoddard]
5485 *) httpd children now re-bind themselves to a random CPU on
5486 multiprocessor systems on AIX via bindprocessor() in 2.0.
5487 [Victor J. Orlikowski]
5489 *) Fix htdigest. It would go into a loop in getline when adding
5490 a second user. [Bill Stoddard]
5492 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
5494 *) Automatically generate httpd.exp for AIX.
5495 DSOs now work again on AIX in 2.0
5496 [Victor J. Orlikowski]
5498 *) Add a new request hook, error_log. This phase allows modules
5499 to act on the error log string _after_ it has been written
5500 to the error log. The goal for this hook is to allow monitoring
5501 modules to send the error string to the monitoring agent.
5504 *) Modify mod_echo to make it use filters for input and output.
5505 [Ryan Morgan <rmorgan covalent.net>]
5507 *) Extend mod_headers to support conditional driven Header
5508 add, append and set. Use SetEnvIf to set an envar and conditionally
5509 add/append/set headers based on this envar thusly:
5511 SetEnvIf TSMyHeader value HAVE_TSMyHeader
5512 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
5514 If the request contains header "TSMyHeader: value" then header
5515 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
5518 *) Extend mod_headers to support using format specifiers on Header
5519 add, append and set header values. Two format specifiers are supported:
5521 %t - reports, in UTC microseconds since the epoch, when the
5522 request was received.
5524 %D - reports the time, in microseconds, between when the request was
5525 received and the response sent.
5528 Header add MyHeader "This request served in %D microseconds. %t"
5530 results in a header being added to the response that looks like this:
5532 MyHeader: This request served in D=5438 microseconds. t=991424704447256
5536 *) Fix reset_filter(). We need to be careful how we remove filters.
5537 If we set r->output_filters to NULL, we also have to reset the
5538 connection's filters. [John Sterling]
5540 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
5542 *) Add a check to ap_die() to make sure the filter stack is sane and
5543 contains the correct basic filters when an error occurs. This fixes
5544 a problem where headers are not being sent on error. [John Sterling]
5546 *) New Header directive 'echo' option. "Header echo regex" will
5547 cause any headers received on the request that match regex to be
5548 echoed to (included in) the response headers.
5551 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
5552 This prevented the inclusion of apr_compat.h. PR #7773
5553 [Oleg Broytmann <phd phd.pp.ru>]
5555 *) Moved util_uri to the apr-util library. This required a bunch of
5556 apr_name changes for the uri utility functions. [Justin Erenkrantz]
5558 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
5559 insert_filter phase so that other filters are not bypassed by default.
5562 *) Reimplement mod_headers as an output filter. mod_headers can now
5563 add custom headers to inbound requests using the RequestHeader directive
5564 and to responses using the same old Header directive. [Graham Leggett]
5566 Changes with Apache 2.0.18
5568 *) Fix command-line processing so that if a bad argument is specified
5569 Apache will exit. [Jeff Trawick]
5571 *) Change the make targets and rules to be consistent in all of the
5572 Apache-owned source trees. [Roy Fielding]
5574 *) Fix processing of the TRACE method. Previously we passed bogus
5575 parms to form_header_field() and it overlaid some vhost structures,
5576 resulting in a segfault in check_hostalias().
5577 [Greg Ames, Jeff Trawick]
5579 *) Win32: Add support for reliable piped logs. If the logging process
5580 goes down, Apache will automatically restart it. This function has
5581 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
5584 *) Do not start piped log processes during the config file
5585 preflight. This change also circumvents a problem on
5586 Windows where the rotatelog processes created during preflight
5587 was not getting cleaned up properly.
5590 *) add "Request Phase Participation" info to mod_info
5593 *) Make first phase changes to the scoreboard data structures in
5594 preparation for the rewriting of the scoreboard per my posted
5595 design notes. [Paul J. Reder]
5597 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
5598 and apr-util, allow it to be overridden by the configure command-line
5599 (default="--silent") and introduce LT_LDFLAGS to replace what we were
5600 formerly abusing as LTFLAGS. [Roy Fielding]
5602 *) Clean up the reporting of incorrect closing container tags.
5603 [Barrie Slaymaker <barries slaysys.com>]
5605 *) Simplify the configure process by moving all libtool stuff to APR
5606 and moving hints.m4 inline. [Roy Fielding]
5608 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
5609 of functions used by mod_proxy for export in the DLL
5610 [Ian Holsman <IanH cnet.com>]
5612 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
5613 request body from its stdin but no reqest body is being written to
5614 the cgi. [Jeff Trawick]
5616 *) mod_log_config: %c connection status incorrectly logged
5617 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
5620 *) Get mod_cern_meta working under Windows
5623 *) Create Files, and thus MMAPs, out of the request pool, not the
5624 connection pool. This solves a small resource leak that had us
5625 not closing files until a connection was closed. In order to do
5626 this, at the end of the core_output_filter, we loop through the
5627 brigade and convert any data we have into a single HEAP bucket
5628 that we know will survive clearing the request_rec.
5629 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
5632 *) Completely revamp configure so that it preserves the standard make
5633 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
5634 the configure additions to EXTRA_* variables. Also, allow the user
5635 to specify NOTEST_* values for all of the above, which eliminates the
5636 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
5637 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
5638 avoid pointless duplications. Fix the order in which flags are given
5639 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
5640 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
5641 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
5642 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
5644 *) Get mod_tls to compile/work better on Windows. PR #7612
5645 [Bernhard Schrenk <b.schrenk improx.com>]
5647 *) Fix shutdown/restart hangs in the threaded MPM.
5648 [Jeff Trawick, Greg Ames, Ryan Bloom]
5650 *) Removed the keptalive boolean from conn_rec because it is now only
5651 used by a single routine and can be replaced by a local variable.
5652 [Greg Stein, Ryan Bloom, Roy Fielding]
5654 *) Patch prefork to put enough of the signal processing back in so that
5655 signals are all handled properly now. The previous patch fixed the
5656 deadlock race condition, but broke the user directed signal handling.
5657 This fixes it to work the way it did before my previous prefork patch
5658 (primarily, SIGTERM is now working).
5660 *) Change how input filters decide how much data is returned to the
5661 higher filter. We used to use a field in the conn_rec, with this
5662 change, we use an argument to ap_get_brigade to determine how much
5663 data is retrieved. [Ryan Bloom]
5665 *) Fix seg fault at start-up introduced by Ryan's change to enable
5666 modules to specify their own logging tags. mod_log_config
5667 registers an optional function, ap_register_log_handler().
5668 ap_register_log_handler() was being called by http_core before
5669 the directive hash table was created. This patch creates the
5670 directive hash table before ap_register_log_handler() is
5671 registered as an optional function.
5672 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
5674 *) Add ap_set_int_slot() function
5675 [John K. Sterling <sterling covalent.net>]
5677 *) Under certain circumstances, Apache did not supply the
5678 right response headers when requiring authentication.
5679 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
5680 (This is a port of the change that went into Apache 1.3.19.)
5682 *) Allow modules to specify their own logging tags. This basically
5683 allows a module to tell mod_log_config that when %x is encountered
5684 a specific function should be called. Currently, x can be any single
5685 character. It may be more useful to make this a string at some point.
5688 Changes with Apache 2.0.17
5690 *) If a higher-level filter handles the byterange aspects of a
5691 request, then the byterange filter should not try to redo the
5692 work. The most common case of this happening, is a byterange
5693 request going through the proxy, and the origin server handles
5694 the byterange request. The proxy should ignore it.
5695 [Graham Leggett <minfrin sharp.fm>]
5697 *) Changed the threaded mpm to have child_main join to each of the
5698 worker threads to make sure the kids are all gone before child_main
5699 exits after a signal (cleanup from perform_idle_server_maintenance).
5700 This is an extension of Ryans recent commit to make the child_main
5703 *) Add more options to the ap_mpm_query function. This also allows MPMs to
5704 report if their threads are dynamic or static. Finally, this also
5705 implements a new API, ap_show_mpm, which returns the MPM that was
5706 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
5708 *) Do not install the binaries from the support directory twice.
5709 [jun-ichiro hagino <itojun iijlab.net>]
5711 *) The ap_f* functions should flush data to the filter that is passed
5712 in, not the filter after the one passed in.
5713 [Ryan Morgan <rmorgan covalent.net>]
5715 *) Make ab work again by changing its native types to apr types and formats.
5716 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
5718 *) Move the byterange filter and all of the supporting functions back
5719 to the HTTP module. The byterange filter turned out to be very
5720 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
5722 *) Make clean, distclean, and extraclean consistently according to the
5723 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
5725 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
5726 This may have been causing problems stopping processes in the threaded
5729 *) Fix content-length in mod_negotiation to a long int representation.
5732 *) Remove BindAddress from the default config file.
5733 [<giles nemeton.com.au>]
5735 *) Allow module authors to add a module to their Apache build using
5736 --with-module, without re-running buildconf. The syntax is:
5737 --with-module=module_type:/path/to/module.c
5738 The configure script will copy the module.c file to
5739 modules/module_type, and it will be added to the relevant Makefiles.
5740 currently, this only works for static modules. [Ryan Bloom]
5742 *) Changes required to make prefork clean up idle children properly.
5743 There was a window during which a starting worker deadlocks when
5744 an idle cleanup arrives before it completes init. Apache then keeps
5745 trying to cleanup the same deadlocked worker forever (until higher
5746 pids come along, but it still will never reduce below the deadlocked
5747 pid). Thus the number of children would not reduce to the correct
5748 idle level. [Paul J. Reder]
5750 Changes with Apache 2.0.16
5752 *) Change the default installation directory to /usr/local/apache2,
5753 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
5755 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
5758 *) Get MaxRequestsPerChild working with the Windows MPM.
5761 *) Make generic hooks to work, with mod_generic_hook_import/export
5762 experimental modules. [Ben Laurie, Will Rowe]
5764 *) Fix segfaults for configuration file syntax errors such as
5765 "<Directory>" followed by "</Directory" and
5766 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
5768 *) Cleanup the --enable-layout option of configure. This makes
5769 us use a consistent location for the config.layout file, and it
5770 makes configure more portable.
5771 [jun-ichiro hagino <itojun iijlab.net>]
5773 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
5774 csv/gnuplot format, rudimentary ssl support and various other tweaks
5775 to make results more true to what is measured. The upshot of this it
5776 turns out that 'ab' has often underreported the true performance of
5777 apache. Often by a order of magnitude :-) See talk/paper of Sander
5778 Temme at April ApacheCon 2001 for details.
5779 [Dirk-Willem van Gulik]
5781 *) Clean up mod_cgid's temporary request pool. Besides fixing a
5782 storage leak this ensures that some unnecessary pipes are closed.
5785 *) Performance: Add quick_handler hook. This hook is called at the
5786 very beginning of the request processing before location_walk,
5787 translate_name, etc. This hook is useful for URI keyed content
5788 caches like Mike Abbott's Quick Shortcut Cache.
5791 *) top_module global variable renamed to ap_top_module [Perl]
5793 *) Move ap_set_last_modified to the core. This is a potentially
5794 controversial change, because this is kind of HTTP specific. However
5795 many protocols should be able to take advantage of this kind of
5796 information. I expect that headers will need one more layer of
5797 indirection for multi-protocol work, but this is a small step in
5798 the right direction. [Ryan Bloom]
5800 *) Enable mod_status by default. This matches what Apache 1.3 does.
5803 *) Add a ScriptSock directive to the default config file. This is
5804 only enabled when mod_cgid is used.
5805 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5807 Changes with Apache 2.0.15
5809 *) Untangled the buildconf script and eliminated the need for build's
5810 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
5811 libtool muck that is now under srclib/apr/build. [Roy Fielding]
5813 *) Win32: Don't accept more connections than we have worker threads
5817 *) Fix bug in the Unix threaded.c MPM that allowed child processes
5818 to fork() new child processes.
5821 *) SECURITY: Fix a major security problem with double-reverse lookup
5822 checking. Previously, a client connecting over IPv4 would not be
5823 matched properly when the server had an IPv6 listening socket.
5824 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
5826 *) Change the way the beos MPM handles polling to allow it to stop and
5827 restart. Problem was the sockets being polled were being reset by
5828 the select call, so once it had accepted a connection it was no
5829 longer listening on the UDP socket we use for shutdown instructions.
5830 APR needs to be altered, patch on it's way. [David Reid]
5832 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
5833 on error exit from ap_getline(). Some other code got upset because
5834 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
5836 *) Handle ap_discard_request_body() being called more than once.
5837 [Greg Ames, Jeff Trawick]
5839 *) Get rid of an inadvertent close of file descriptor 2 in
5840 mod_mime_magic. [Greg Ames, Jeff Trawick]
5842 *) Add a hook, create_request. This hook allows modules to modify
5843 a request while it is being created. This hook is called for all
5844 request_rec's, main request, sub request, and internal redirect.
5845 When this hook is called, the r->main, r->prev, r->next
5846 pointers have been set, so modules can determine what kind of
5847 request this is. [Ryan Bloom]
5849 *) Cleanup the build process a bit more. The Apache configure
5850 script no longer creates its own helper scripts, it just
5852 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
5854 *) Stop the forced downgrade of the connection to HTTP/1.0 for
5855 proxy requests. [Graham Leggett]
5857 *) Avoid using sscanf to determine the HTTP protocol number in
5858 the common case because sscanf is a performance hog. From
5859 Mike Abbot's Accelerating Apache patch number 6.
5860 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
5862 *) SECURITY: Fix a security exposure in mod_access. Previously when
5863 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
5864 were not evaluated properly (PR #7407). Also, add the ability to
5865 specify IPv6 address strings with optional prefix length on Allow
5866 and Deny. [Jeff Trawick]
5868 *) Enhance rotatelogs so that a UTC offset can be specified, and
5869 the logfile name can be formatted using strftime(3). (Brought
5870 forward from 1.3.) [Ken Coar]
5872 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
5873 DuplicateHandle on an IOCompletionPort (a practice which
5874 MS "discourages"). The new model does not rely on associating
5875 the completion port with the listening sockets, thus the
5876 completion port can be completely managed within the child
5877 process. A dedicated thread accepts connections off the network,
5878 then calls PostQueuedCompletionStatus() to wake up worker
5879 threads blocked on the completion port.
5882 *) Bring forward the --suexec-umask option which allows the
5883 builder to preset the umask for suexec processes. [Ken Coar]
5885 *) Add a -V flag to suexec, which causes it to display the
5886 compile-time settings with which it was built. (Only
5887 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
5889 *) Mod_include should always unset the content-length if the file is
5890 going to be passed through send_parsed_content. There is no to
5891 determine if the content will change before actually scanning the
5892 entire content. It is far safer to just remove the C-L as long
5893 as we are scanning it. [Ryan Bloom]
5895 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
5896 request and not Proxy-Authenticate.
5897 [Graham Leggett <minfrin sharp.fm>]
5899 Changes with Apache 2.0.14
5901 *) Fix content-length computation. We ONLY compute a content-length if
5902 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
5903 or we already have all the data. [Ryan Bloom]
5905 *) Report unbounded containers in the config file. Previously, a typo
5906 in the </container> directive could result in the rest of the config
5907 file being silently ignored, with undesired defaults used.
5910 *) Make the old_write filter use the ap_f* functions for the buffering.
5913 *) Move more code from the http module into the core server. This
5914 is core code, basically the default handler, the default input
5915 and output filters, and all of the core configuration directives.
5916 All of this code is required in order for the server to work, with or
5917 without HTTP. The server is closer to working without the HTTP
5918 module, although there is still more to do. [Ryan Bloom]
5920 *) Fix a number of SGI compile warnings throughout the server. Fix some
5921 bad parameters to apr_bucket_read(). Fix a bad statement in
5922 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
5923 consistently; we were mixing apr_time_t and time_t in invalid ways
5924 before. In load_file(), call apr_dso_error() instead of
5925 apr_strerror() so that we get a more specific string on some platforms.
5926 PR #6980 [Jeff Trawick]
5928 *) Allow modules to query the MPM about it's execution profile. This
5929 query API can and should be extended in the future, but for now,
5930 max_daemons, and threading or forking is a very good start.
5931 [Jon Travis <jtravis covalent.net>]
5933 *) Modify mod_include to send blocks of data no larger than 9k.
5934 Without this, mod_include will wait until the whole file is parsed,
5935 or the first tag is found to send any data to the client.
5936 [Paul J. Reder <rederpj raleigh.ibm.com>]
5938 *) Fix mod_info, so that <Directory> and <Location> directives are
5939 not displayed twice when displaying the current configuration.
5940 [Ryan Morgan <rmorgan covalent.net>]
5942 *) Add config directives to override DEFAULT_ERROR_MSG and
5943 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
5944 [Dan Rench <drench xnet.com>]
5946 *) Get mod_info building and loading on Win32. [William Rowe]
5948 *) Begin to move protocol independant functions out of mod_http. The goal
5949 is to have only functions that are HTTP specific in the http directory.
5952 Changes with Apache 2.0.13
5954 *) Don't assume that there will always be multiple calls to the byterange
5955 filter. It is possible that we will need to do byteranges with only
5956 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
5958 *) Move the error_bucket definition from the http module to the
5959 core server. Every protocol will need this ability, not just
5962 Changes with Apache 2.0.12
5964 *) Modify mod_file_cache to save pre-formatted strings for
5965 content-length and last-modified headers for performance.
5966 [Mike Abbot <mja trudge.engr.sgi.com>]
5968 *) Namespace protect IOBUFSIZ since it is exposed in the API.
5969 [Jon Travis <jtravis covalent.net>]
5971 *) Use "Basic" authentication instead of "basic" in ab, as the spec
5972 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
5974 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
5975 without ever filling it out. This fixes PR 7271.
5976 [Taketo Kabe <kabe sra-tohoku.co.jp> and
5977 Cliff Woolley <cliffwoolley yahoo.com>]
5979 *) Add a couple of GCC attribute tags to printf style functions.
5980 [Jon Travis <jtravis covalent.net>]
5982 *) Add the correct language tag for interoperation with the Taiwanese
5983 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
5985 *) Migrate the perchild MPM to use the new apr signal child, and
5986 APR thread functions. [Ryan Bloom]
5988 *) Close one copy of the CGI's stdout before creating the new process.
5989 The CGI will still have stdout, because we have already dup'ed it.
5990 This keeps Apache from waiting forever to send the results of a CGI
5991 process that has forked a long-lived child process.
5992 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5994 *) Remove the rest of the pthreads functions from the threaded MPM.
5995 This requires the APR support for a signal thread that was just
5998 *) Make mod_dir use a fixup for sending a redirect to the browser.
5999 Before this, we were using a handler, which doesn't make much
6000 sense, because the handler wasn't generating any data, it would
6001 either return a redirect error code, or DECLINED. This fits the
6002 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
6004 *) Make the threaded MPM use APR threads instead of pthreads.
6007 *) Get mod_tls to the point where it actually appears to work in all cases.
6010 *) implement --enable-modules and --enable-mods-shared for "all" and
6011 "most". [Greg Stein]
6013 *) Move the threaded MPM to use APR locks instead of pthread locks.
6016 *) Rename mpmt_pthread to threaded. This is more in line with the
6017 fact that mpmt_pthread shouldn't be using pthreads directly, and
6018 it is a smaller name that doesn't tie into anything.
6021 *) Rename the module structures so that the exported symbol matches
6022 the file name, and it is easier to automate the installation
6023 process (generating LoadModule directives from the module filenames).
6026 *) Remove the coalesce filter. With the ap_f* functions, this filter
6027 is no longer needed. [Ryan Bloom]
6029 Changes with Apache 2.0.11
6031 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
6032 added feature of allowing a uid/gid per child process. If no
6033 uid/gid is specified, then Perchild behaves exactly like dexter.
6036 *) Get perchild building again. [Ryan Bloom]
6038 *) Don't disable threads just because we are using the prefork MPM.
6039 If somebody wants to compile without threads, they must now add
6040 --disable-threads to the configure command line. [Ryan Bloom]
6042 *) Begin to move the calls to update_child_status into common code, so
6043 that each individual MPM does not need to update the scoreboard itself.
6046 *) Allow mod_tls to compile under Unix boxes where openssl has been
6047 installed to the system include files.
6048 [Gomez Henri <new-httpd slib.fr>]
6050 *) Cleanup the mod_tls configure process. This should remove any need
6051 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
6052 configure doesn't check that yet. [Ryan Bloom]
6054 *) Add a very early prototype of SSL support (in mod_tls.c). It is
6055 vital that you read modules/tls/README before attempting to build
6058 *) Fix a potential seg fault on all platforms. David Reid fixed this
6059 on BEOS, but the problem could happen anywhere, so we don't want
6060 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
6062 *) Add new LogFormat directive, %D, to log time it takes to serve a
6063 request in microseconds. [Bill Stoddard]
6065 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
6066 SetOutputFilter. This corresponds nicely with the other Set
6067 directives, which operate on containers while the Add* directives
6068 tend to work directly on extensions. [Ryan Bloom]
6070 *) Cleanup the header handling a bit. This uses the apr_brigade_*
6071 functions for the buffering so that we don't need to compute
6072 the length of the headers before we actually create the header
6073 buffer. [Ryan Bloom]
6075 *) Allow filters to buffer data using the ap_f* functions. These have
6076 become macros that resolve directly to apr_brigade_*.
6079 *) Get the Unix MPM's to do a graceful restart again. If we are going
6080 to register a cleanup with ap_cleanup_scoreboard, then we have to
6081 kill the cleanup with the same function, and that function can't be
6082 static. [Ryan Bloom]
6084 *) Install all required header files. Without these, it was not
6085 possible to compile some modules outside of the server.
6088 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
6089 forward from 1.3 to 2.0, we missed a single line, which broke regex
6090 aliases. [Ryan Bloom]
6092 *) We have a poor abstraction in the protocol. This is a temporary
6093 hack to fix the bug, but it will need to be fixed for real. If
6094 we find an error while sending out a custom error response, we back
6095 up to the first non-OK request and send the data. Then, when we send
6096 the EOS from finalize_request_protocol, we go to the last request,
6097 to ensure that we aren't sending an EOS to a request that has already
6098 received one. Because the data is sent on a different request than
6099 the EOS, the error text never gets sent down the filter stack. This
6100 fixes the problem by finding the last request, and sending the data
6101 with that request. [Ryan Bloom]
6103 *) Make the server status page show the correct restart time, and
6104 thus the proper uptime. [Ryan Bloom]
6106 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
6107 should reduce the amount of duplicate code that is required to
6108 create CGI processes.
6109 [Paul J. Reder <rederpj raleigh.ibm.com>]
6111 *) ap_new_connection() closes the socket and returns NULL if a socket
6112 call fails. Usually this is due to a connection which has been
6113 reset. [Jeff Trawick]
6115 *) Move the Apache version information out of httpd.h and into release.h.
6116 This is in preparation for the first tag with the new tag and release
6117 system. [Ryan Bloom]
6119 *) Begin restructuring scoreboard code to enable adding back in
6120 the ability to use IPC other than shared memory.
6121 Get mod_status working on Windows again. [Bill Stoddard]
6123 *) Make mod_status work with 2.0. This will work for prefork,
6124 mpmt_pthread, and dexter. [Ryan Bloom]
6126 *) Correct a typo in httpd.conf.
6127 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
6129 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
6131 *) Get the correct IP address if ServerName isn't set and we can't
6132 find a fully-qualified domain name at startup.
6133 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
6135 *) Make mod_cgid work with SuExec. [Ryan Bloom]
6137 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
6138 'extra' stat's for user/group since they should never occur, and now
6139 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
6140 volumes. [William Rowe]
6142 *) Adopt apr features to simplify mod_includes. This changes the
6143 behavior of the USER_NAME variable, unknown uid's are now reported
6144 as USER_NAME="<unknown>" rather than the old user#000 result.
6145 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
6147 *) Adopt apr features for simplifing mod_userdir, and accept the new
6148 Win32/OS2 exceptions without hiccuping. [William Rowe]
6150 *) Replace configure --with-optim option by using and saving the
6151 environment variable OPTIM instead. This is needed because configure
6152 options do not support multiple flags separated by spaces.
6155 *) Fix some byterange handling. If we get a byte range that looks like
6156 "-999999" where that is past the end of the file, we should return
6157 a PARTIAL CONTENT status code, and return the whole file as one big
6158 byterange. This matches the 1.3 handling now. [Ryan Bloom]
6160 *) Make the error bucket a real meta-data bucket. This means that the
6161 bucket length is 0, and a read returns NULL data. If one of these
6162 buckets is passed down after the headers are sent, this data will
6163 just be ignored. [Greg Stein]
6165 *) The prefork MPM wasn't killing child processes correctly if a restart
6166 signal was received while the process was serving a request. The child
6167 process would become the equivalent of a second parent process. If
6168 we break out of the accept loop, then we need to do die after cleaning
6169 up after ourselves. [Ryan Bloom]
6171 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
6172 restarts. [Ryan Bloom]
6174 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
6175 the most optimal APR_FINFO_wanted bits. This spares Win32 from
6176 performing very expensive owner, group and permission lookups
6177 and allows the server to function until these apr_finfo_t fields
6178 are implemented under Win32. [William Rowe]
6180 *) Support for typedsafe optional functions - that is functions exported by
6181 optional modules, which, therefore, may or may not be present, depending
6182 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
6183 for sample code. [Ben Laurie]
6185 *) filters can now report an HTTP error to the server. This is done
6186 by sending a brigade where the first bucket is an error_bucket.
6187 This bucket is a simple bucket that stores an HTTP error and
6188 a string. Currently the string is not used, but it may be needed
6189 to output an error log. The http_header_filter will find this
6190 bucket, and output the error text, and then return
6191 AP_FILTER_ERROR, which informs the server that the error web page
6192 has already been sent. [Ryan Bloom]
6194 *) If we get an error, then we should remove all filters except for
6195 those critical to serving a web page. This fixes a bug, where
6196 error pages were going through the byterange filter, even though
6197 that made no sense. [Ryan Bloom]
6199 *) Relax the syntax checking of Host: headers in order to support
6200 iDNS. PR#6635 [Tony Finch]
6202 *) Cleanup the byterange filter to use the apr_brigade_partition
6203 and apr_bucket_copy functions. This removes a lot of very messy
6204 code, and hopefully makes this filter more stable.
6207 *) Remove AddModule and ClearModuleList directives. Both of these
6208 directives were used to ensure that modules could be enabled
6209 in the correct order. That requirement is now gone, because
6210 we use hooks to ensure that modules are in the correct order.
6213 *) When SuExec is specified, we need to add it to the list of
6214 targets to be built. If we don't, then any changes to the
6215 configuration won't affect SuExec, unless 'make suexec' is
6216 specifically run. [Ryan Bloom]
6218 *) Cleaned out open_file from mod_file_cache, as apr now accepts
6219 the APR_XTHREAD argument to open a file for consumption by
6220 parallel threads on win32. [William Rowe]
6222 *) Correct a bug in determining when we follow symlinks. The code
6223 expected a stat -1 result, not an apr_status_t positive error.
6224 Also check if the APR_FINFO_USER fields are valid before we
6225 follow the link. [William Rowe]
6227 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
6228 mpm_common.c. These functions are only valid on some platforms,
6229 so they should not be in the main-line code. [Ryan Bloom]
6231 *) Remove ap_chdir_file(). This function is not thread-safe,
6232 and nobody is currently using it. [Ryan Bloom]
6234 *) Do not try to run make depend if there are no .c files in the
6235 current directory, doing so makes `make depend` fail.
6238 *) Update highperformance.conf to work with either prefork or
6239 pthreads mpms. [Greg Ames]
6241 *) Stop checking to see if this is a pipelined request if we know
6242 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
6243 This keeps us from making an extra read call when serving a 1.0
6244 request. [Ryan Bloom and Greg Stein]
6246 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
6247 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
6248 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
6250 *) Fix the RFC number mentioned when complaining about a missing
6251 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
6253 *) Fix an endless loop in ab which occurred when ab was posting
6254 and the server dropped the connection unexpectedly.
6257 *) Fix a segfault while handling request bodies in ap_http_filter().
6258 This problem has been seen with mod_dav usage as well as with
6259 requests where the body was just being discarded. [Jeff Trawick]
6261 *) Some adjustment on the handling and automatic setting (via
6262 hints.m4) of various compilation flags (eg: CFLAGS). Also,
6263 add the capability to specify flags (NOTEST_CFLAGS and
6264 NOTEST_LDFLAGS) which are used to compile Apache, but
6265 not used during the configuration process. Useful for
6266 flags like "-Werror". [Jim Jagielski]
6268 *) Stop using environment variables to force debug mode or
6269 no detach. We now use the -D command line argument to
6270 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
6271 [Greg Stein, Ryan Bloom]
6273 *) Change handlers to use hooks. [Ben Laurie]
6275 *) Stop returning copies of filenames from both apr_file_t and
6276 apr_dir_t. We pstrdup the filenames that we store in the
6277 actual structures, so we don't need to pstrdup the strings again.
6280 *) mod_cgi: Fix some problems where the wrong error value was being
6281 traced. [Jeff Trawick]
6283 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
6286 *) Add generic hooks. [Ben Laurie]
6288 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
6290 *) Fix a segfault caused by mod_ext_filter when the external filter
6291 program does not exist. [Jeff Trawick]
6293 *) Fix an output truncation error when on an HTTP >= 1.0 request an
6294 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
6295 was served through mod_charset_lite (or anything else that would
6296 create a transient bucket in this size range). ap_bucket_make_heap()
6297 silently failed (fixed), transient_setaside() discovered it, but
6298 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
6300 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
6301 is that some browsers send extra lines at the end of POST requests, and
6302 we don't want to delay sending data back to the user just because the
6303 browser isn't well behaved. [Ryan Bloom]
6305 *) Get SuEXEC working again. We can't send absolute paths to suExec
6306 because it refuses to execute those programs. SuEXEC also wasn't
6307 always recognizing configuration changes made using the autoconf
6310 *) Allow the buildconf process to find the config.m4 files in the correct
6311 order. Basically, we can now name config.m4 files as config\d\d.m4,
6312 and we will sort them correctly when inserting them into the build
6313 process. [Ryan Bloom]
6315 *) Get mod_cgid to use apr calls for creating the actual CGI process.
6316 This also allows mod_cgid to use ap_os_create_priviledged_process,
6317 thus allowing for SuExec execution from mod_cgid. Currently, we do
6318 not support everything that standard SuExec supports, but at least
6319 it works minimally now. [Ryan Bloom]
6321 *) Allow SuExec to be configured from the ./configure command line.
6324 *) Update some of the docs in README and INSTALL to reflect some of
6325 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
6327 *) If we get EAGAIN returned from the call to apr_sendfile, then we
6328 need to call sendfile again. This gets us serving large files
6329 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
6331 *) Get the support programs building cleanly again.
6332 [Cliff Woolley <cliffwoolley yahoo.com>]
6334 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
6335 current directory logic now backs up over bin/ to determine the
6336 server root from the Apache.exe path.
6338 *) Apache/Win32 now follows the standard conventions of mod_foo.so
6339 loadable modules, dynamic libs are all named libfoo.dll, and the
6340 makefile.win populates the include, lib and libexec directories.
6342 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
6343 Apache gets IPv6 listening sockets by default. Additionally, the
6344 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
6345 numeric address strings (e.g., "Listen [fe80::1]:8080").
6348 *) Modify the install directory layout. Modules are now installed in
6349 modules/. Shared libraries should be installed in libraries/, but
6350 we don't have any of those on Unix yet. All install directories
6351 are modifyable at configure time. [Ryan Bloom]
6353 *) Install all header files in the same directory on Unix. [Ryan Bloom]
6355 *) Get the functions in server/linked into the server, regardless of
6356 which modules linked into the server. This uses the same hack
6357 for Apache that we use for APR and apr-util to ensure all of the
6358 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
6359 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
6360 the scripts a bit easier.
6363 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
6364 on the query, and remove IPv4 dependencies. [Jeff Trawick]
6366 *) Get all of the auth modules to the point that they will install and
6367 be loadable into the server. Our new build/install mechanism expects
6368 that all modules will have a common name format. The auth modules
6369 didn't use that format, so we didn't install them properly.
6372 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
6373 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
6375 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
6377 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
6378 after the end of the response. [Ryan Bloom]
6380 *) Get byterange requests working with responses that do not have a
6381 content-length. Because of the way byterange requests work, we have to
6382 have all of the data before we can actually do the byterange, so we
6383 can compute the content-length in the byterange filter.
6386 *) Get exe CGI's working again on Windows.
6389 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
6390 they keep track of whether or not their post config hook has been
6391 called before. Instead of a static variable (which is replaced when
6392 the DSO is loaded a second time), use userdata in the process pool.
6395 Changes with Apache 2.0a9
6397 *) Win32 now requires perl to complete the final install step for users
6398 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
6399 and installs the conf, htdocs and htdocs/manual directories.
6402 *) Make mod_include use a hash table to associate directive tags with
6403 functions. This allows modules to implement their own SSI tags easily.
6404 The idea is simple enough, a module can insert it's own tag and function
6405 combination into a hash table provided by mod_include. While mod_include
6406 parses an SSI file, when it encounters a tag in the file, it does a
6407 hash lookup to find the function that implements that tag, and passes
6408 all of the relevant data to the function. That function is then
6409 responsible for processing the tag and handing the remaining data back
6410 to mod_include for further processing.
6411 [Paul J. Reder <rederpj raleigh.ibm.com>]
6413 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
6414 fewer parameters: the local and remote socket addresses were removed
6415 from the parameter list because all required information is available
6416 via the APR socket. [Jeff Trawick]
6418 *) Distribution directory structure reorganized to reflect a
6419 normal source distribution with external install targets.
6422 *) The MPMs that need multiple segments of shared memory now create
6423 two apr_shmem_t variables, one for each shared memory allocation.
6424 the problem is that we can't determine how much memory will be required
6425 for shared memory allocations once we try to allocate more than one
6426 variable. The MM code automatically aligns the shared memory allocations,
6427 so we end up needing to pad the amount of shared memory we want based
6428 on how many variables will be allocated out of the shared memory segment.
6429 It is just easier to create a second apr_shmem_t variable, and two
6430 shmem memory blocks.
6433 *) Cleanup the export list a bit. This creates a single unified list of
6434 functions exported by APR. The export list is generated at configure
6435 time, and that list is then used to generate the exports.c file.
6436 Because of the way the export list is generated, we only export those
6437 functions that are valid on the platform we are building on.
6440 *) Enable logging the cookie with mod_log_config
6441 [Sander van Zoest <sander covalent.net>]
6443 *) Fix a segfault in mod_info when it reaches the end of the configuration.
6446 *) Added lib/aputil/ as a placeholder for utility functions which are not
6447 specific to the Apache HTTP Server (but do not make sense with APR).
6448 The first utility is "apu_dbm": a set of functions to work with DBM
6449 files. This first version can be compiled for SDBM or GDBM databases.
6452 *) Complete re-write of mod_include. This makes mod_include a filter that
6453 uses buckets directly. This has now served the FAQ correctly.
6454 [Paul Reder <rederpj raleigh.ibm.com>]
6456 *) Allow modules to specify the first filter in a sub_request when
6457 making the sub_request. This keeps modules from having to change the
6458 output_filter immediately after creating the sub-request, and therefore
6459 skip the sub_req_output_filter. [Ryan Bloom]
6461 *) Update ab to accept URLs with IPv6 literal address strings (in the
6462 format described in RFC 2732), and to build Host header fields in
6463 the same format. This allows IPv6 literal address strings to be
6464 used with ab. This support has been tested against Apache 1.3 with
6465 the KAME patch, but Apache 2.0 does not yet work with this format
6466 of the Host header field. [Jeff Trawick]
6468 *) Accomodate an out-of-space condition in the piped logs and the
6469 rotatelogs.c code, and no longer churn log processes for this
6470 condition. [Victor J. Orlikowski]
6472 *) Add support for partial writes with apr_sendfile() to core_output_filter.
6475 Changes with Apache 2.0a8
6477 *) Add a directive to mod_mime so that filters can be associated with
6481 *) Get multi-views working again. We were setting the path_info
6482 field incorrectly if we couldn't find the specified file.
6485 *) Fix 304 processing. The core should never try to send the headers
6486 down the filter stack. Always, just setup the table in the request
6487 record, and let the header filter convert it to data that is ready
6491 *) More fixes for the proxy. There are still bugs in the proxy code,
6492 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
6496 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
6499 *) APR: Add new apr_getopt_long function to handle long options.
6500 [B. W. Fitzpatrick <fitz red-bean.com>]
6502 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
6503 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
6504 hostname resolution/address string parsing and building
6505 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
6506 of one of the apr_sockaddr_t structures for a socket. Change
6507 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
6509 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
6510 I have proxied pages with it, cleanup will commence soon.
6513 *) Make the proxy work with filters. This isn't perfect, because we
6514 aren't dealing with the headers properly. [Ryan Bloom]
6516 *) Do not send a content-length iff the C-L is 0 and this is a head
6517 request. [Ryan Bloom]
6519 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
6520 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
6522 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
6524 *) Get the default_handler to stop trying to deal with HEAD requests.
6525 The idea is to let the content-length filter compute the C-L before
6526 we try to send the data. If we can get the C-L correctly, then we
6527 should send it in the HEAD response.
6530 *) The Header filter can now determine if a body should be sent based
6531 on r->header_only. The general idea of this is that if we delay
6532 deciding to send the body, then we might be able to compute the
6533 content-length correctly, which will help caching proxies to cache
6534 our data better. Any handler that doesn't want to try to compute
6535 the content-length can just send an EOS bucket without data and
6536 everything will just work.
6539 *) Add the referer to the error log if one is available.
6540 [Markus Gyger <mgyger itr.ch>]
6542 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
6543 change, the root of the configuration tree has been exposed to modules
6545 [Ryan Morgan <rmorgan covalent.net>]
6547 *) Get the core_output_filter to use the bucket interface directly.
6548 This keeps us from calling the content-length filter multiple times
6549 for a simple static request.
6552 *) We are sending the content-type correctly now.
6553 [Ryan Bloom and Will Rowe]
6555 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
6556 a bogus bytes-sent value when the only thing being sent was trailers
6557 and writev() returned an error (or EAGAIN). [Jeff Trawick]
6559 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
6560 hints file to determine which platforms define
6561 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
6564 *) APR: add apr_get_home_directory() [Jeff Trawick]
6566 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
6568 *) Not all platforms have INADDR_NONE defined by default. Apache
6569 used to make this check and define INADDR_NONE if appropriate,
6570 but APR needs the check too, and I suspect other applications will
6571 as well. APR now defines APR_INADDR_NONE, which is always a valid
6572 value on all platforms.
6573 [Branko Čibej <brane xbc.nu>]
6575 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
6576 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
6578 *) Relax the syntax checking of Host: headers in order to support
6579 iDNS. PR#6635 [Tony Finch]
6581 *) When reading from file buckets we convert to an MMAP if it makes
6582 sense. This also simplifies the default handler because the
6583 default handler no longer needs to try to create MMAPs.
6586 *) BUFF has been removed from the main server. The BUFF code will remain
6587 in the code until it has been purged from the proxy module as well.
6590 *) Byteranges have been completely re-written to be a filter. This
6591 has been tested, and I believe it is working correctly, but it could
6592 doesn't work for the Adobe Acrobat plug-in. The output almost matches
6593 the output from 1.3, the only difference being that 1.3 includes
6594 a content-length in the response, and this does not.
6597 *) APR read/write functions and bucket read functions now operate
6598 on unsigned integers, instead of signed ones. It doesn't make
6599 any sense to use signed ints, because we return the error codes,
6600 so if we have an error we should report 0 bytes read or written.
6603 *) Always compute the content length, whether it is sent or not.
6604 The reason for this, is that it allows us to correctly report
6605 the bytes_sent when logging the request. This also simplifies
6606 content-length filter a bit, and fixes the actual byte-reporing
6607 code in mod_log_config.c
6610 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
6611 it says, because it was only used by EOS and FLUSH buckets. Since
6612 neither of those are required at the end of a brigade, this was
6613 really signifying FLUSH_THE_DATA, but that can be determined better
6614 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
6615 buckets now return a length of 0, which is actually the amount of data
6616 read, so they make more sense.
6619 *) Allow the core_output_filter to save some data past the end of a
6620 request. If we get an EOS bucket, we only send the data if it
6621 makes sense to send it. This allows us to pipeline request
6622 responses. As a part of this, we also need to allocate mmap
6623 buckets out of the connection pool, not the request pool. This
6624 allows the mmap to outlive the request.
6627 *) Make blocking and non-blocking bucket reads work correctly for
6628 sockets and pipes. These are the only bucket types that should
6629 have non-blocking reads, because the other bucket types should
6630 ALWAYS be able to return something immediately.
6633 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
6634 server, but use Ctrl+Break to initiate a graceful restart
6635 instead of duplicating behavior. [John Sterling]
6637 *) Patch mod_autoindex to set the Last-Modified header based on
6638 the directory's mtime, and add the ETag header. [William Rowe]
6640 *) Merge the 1.3 patch to add support for logging query string in
6641 such a way that "%m %U%q %H" is the same as "%r".
6644 *) Port three log methods from mod_log_config 1.3 to 2.0:
6645 CLF compliant '-' byte count, method and protocol.
6648 *) Add a new LogFormat directive, %c, that will log connection
6649 status at the end of the response as follows:
6650 'X' - connection aborted before the response completed.
6651 '+' - connection may be kept-alive by the server.
6652 '-' - connection will be closed by the server.
6655 *) Expand APR for WinNT to fully accept and return utf-8 encoded
6656 Unicode file names and paths for Win32, and tag the Content-Type
6657 from mod_autoindex to reflect that charset if the feature
6658 macro APR_HAS_UNICODE_FS is true. [William Rowe]
6660 *) Compute the content length (and add appropriate header field) for
6661 the response when no content length is available and we can't use
6662 chunked encoding. [Jeff Trawick]
6664 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
6665 so that content input filters get dechunked data when using
6666 the default handler. Also removed REQUEST_CHUNKED_PASS.
6669 *) Add mod_ext_filter as an experimental module. This module allows
6670 the administrator to use external programs as filters. Currently,
6671 only filtering of output is supported. [Jeff Trawick]
6673 *) Most Apache functions work on EBCDIC machines again, as protocol
6674 data is now translated (again). [Jeff Trawick]
6676 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
6677 the EBCDIC support. They are noops on ASCII machines, so this
6678 type of translation doesn't have to be surrounded by #ifdef
6679 CHARSET_EBCDIC. [Jeff Trawick]
6681 *) Fix mod_include. tag commands work again, and the server will
6682 send the FAQ again. This also allows mod_include to set aside
6683 buckets that include partial buckets.
6684 [Ryan Bloom and David Reid]
6686 *) Add suexec support back. [Manoj Kasichainula]
6688 *) Lingering close now uses the socket directly instead of using
6689 BUFF. This has been tested, but since all we can tell is that it
6690 doesn't fail, this needs to be really hacked on.
6693 *) Allow filters to modify headers and have those headers be sent to
6694 the client. The idea is that we have an http_header filter that
6695 actually sends the headers to the network. This removes the need
6696 for the BUFF to send headers.
6699 *) Charset translation: mod_charset_lite handles translation of
6700 request bodies. Get rid of the xlate version of ap_md5_digest()
6701 since we don't compute digests of filtered (e.g., translated)
6702 response bodies this way anymore. (Note that we don't do it at
6703 all at the present; somebody needs to write a filter to do so.)
6706 *) Input filters and ap_get_brigade() now have a input mode parameter
6707 (blocking, non-blocking, peek) instead of a length parameter.
6710 *) Update the mime.types file to the registered media types as
6711 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
6714 *) Namespace protect some macros declared in ap_config.h
6717 *) Support HTTP header line folding with input filtering.
6720 *) Mod_include works again. This should still be re-written, but at
6721 least now we can serve an SHTML page again.
6724 *) Begin to remove BUFF from the core. Currently, we keep a pointer
6725 to both the BUFF and the socket in the conn_rec. Functions that
6726 want to use the BUFF can, functions that want to use the socket,
6727 can. They point to the same place.
6730 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
6731 [Tomas Ögren <stric ing.umu.se>]
6733 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
6734 associated pool goes away. (APR pipes on OS/2 were already had this
6735 logic.) This resolvs a fatal file descriptor leak with CGIs.
6738 *) The final line of the config file was not being read if there was
6739 no \n at the end of it. This was caused by apr_fgets returning
6740 APR_EOF even though we had read valid data. This is solved by
6741 making cfg_getline check the buff that was returned from apr_fgets.
6742 If apr_fgets return APR_EOF, but there was data in the buf, then we
6743 return the buf, otherwise we return NULL.
6746 *) Piped logs work again in the 2.0 series.
6749 *) Restore functionality broken by the mod_rewrite security fix:
6750 rewrite map lookup keys and default values are now expanded
6751 so that the lookup can depend on the requested URI etc.
6752 PR #6671 [Tony Finch]
6754 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
6755 security bug in some mass virtual hosting configurations
6756 that can allow a remote attacker to retrieve some files
6757 on the system that should be inaccessible. [Tony Finch]
6759 *) Add a pool bucket type. This bucket is used for data allocated out
6760 of a pool. If the pool is cleaned before the bucket is destroyed, then
6761 the data is converted to a heap bucket, allowing it to survive the
6765 *) Add a flush bucket. This allows modules to signal that the filters
6766 should all flush whatever data they currently have. There is no way
6767 to actually force them to do this, so if a filter ignores this bucket,
6768 that's life, but at least we can try with this.
6771 *) Add an output filter for sub-requests. This filter just strips the
6772 EOS bucket so that we don't confuse the main request's core output
6773 filter by sending multiple EOS buckets. This change also makes sub
6774 requests start to send EOS buckets when they are finished.
6777 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
6778 makes ap_bucket_destroy a return void, which is okay because it
6779 used to always return APR_SUCCESS, and nobody ever checked its
6780 return value anyway.
6781 [Cliff Woolley <cliffwoolley yahoo.com>]
6783 *) Remove the index into the bucket-type table from the buckets
6784 structure. This has now been replaced with a pointer to the
6785 bucket_type. Also add some macros to test the bucket-type.
6788 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
6789 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
6790 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
6791 All _VAR_ flavors changes to _DATA to be absolutely clear.
6794 *) Add support for /, //, //servername and //server/sharename
6795 parsing of <Directory> blocks under Win32 and OS2.
6796 [Tim Costello, William Rowe, Brian Harvard]
6798 *) Remove the function pointers from the ap_bucket type. They have been
6799 replaced with a global table. Modules are allowed to register bucket
6800 types and use then use those buckets.
6803 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
6804 once we finish writing the request body to the cgi child process;
6805 otherwise, the client doesn't hit EOF on stdin. Small request bodies
6806 worked without this change (for reasons I don't understand), but large
6807 ones didn't. [Jeff Trawick]
6809 *) Remove file bucket specific information from the ap_bucket type.
6810 This has been moved to a file_bucket specific type that hangs off
6811 the data pointer in the ap_bucket type.
6814 *) Input filtering now has a third argument. This is the amount of data
6815 to read from lower filters. This argument can be -1, 0, or a positive
6816 number. -1 means give me all the data you have, I'll deal with it and
6817 let you know if I need more. 0 means give me one line and one line
6818 only. A positive number means I want no more than this much data.
6820 Currently, only 0 and a positive number are implemented. This allows
6821 us to remove the remaining field from the conn_rec structure, which
6825 *) Big cleanup of the input filtering. The goal is that http_filter
6826 understands two conditions, headers and body. It knows where it is
6827 based on c->remaining. If c->remaining is 0, then we are in headers,
6828 and http_filter returns a line at a time. If it is not 0, then we are
6829 in body, and http_filter returns raw data, but only up to c->remaining
6830 bytes. It can return less, but never more.
6831 [Greg Ames, Ryan Bloom, Jeff Trawick]
6833 *) mod_cgi: Write all of the request body to the child, not just what
6834 the kernel would accept on the first write. [Jeff Trawick]
6836 *) Back out the change that moved the brigade from the core_output_filters
6837 ctx to the conn_rec. Since all requests over a given connection
6838 go through the same core_output_filter, the ctx pointer has the
6842 *) Fix another bug in the send_the_file() read/write loop. A partial
6843 send by apr_send would cause unsent data in the read buffer to
6844 get clobbered. Complete making send_the_file handle partial
6845 writes to the network.
6848 *) Fix a couple of type fixes to allow compilation on AIX again
6849 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
6851 *) Fix bug in send_the_file() which causes offset to be ignored
6852 if there are no headers to send.
6855 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
6856 filter. Useful for supporting Windows 9* with a binary
6857 compiled on Windows NT.
6860 Changes with Apache 2.0a7
6862 *) Reimplement core_output_filter to buffer/save bucket brigades
6863 across multiple calls to the core_filter. The brigade will be
6864 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
6865 thresholds are hit or the EOS bucket is received.
6868 *) Create experimental filter (buffer_filter) that coalesces bytes
6869 into one large buffer before invoking the next filter in the
6870 chain. This filter is particularly useful with the current
6871 implementation of mod_autoindex when it inserted above the
6872 chunk_filter. mod_autoindex generates a lot of brigades that
6873 containing buckets holding just a few bytes each. The
6874 buffer_filter coalesces these buckets into a single large bucket.
6877 *) Add apr_sendfile() support into the core_output_filter.
6880 *) Add apr_sendv() support into the core_output_filter.
6883 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
6884 [Mike Abbott <mja sgi.com>]
6886 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
6887 make much sense, because Apache uses buckets instead of BUFFs now.
6890 *) send_the_file now falls back to a read/write loop on platforms that
6891 do not have sendfile.
6892 [Ryan Bloom and Brian Havard]
6894 *) Install apachectl correctly, and substitute the proper values so
6895 that it works again. [Ryan Bloom]
6897 *) Better(??) handle platforms that lack sendfile().
6900 *) APR now has UUID generation/formatting/parsing support.
6903 *) Begin the http_filter. This is an input filter that understands
6904 the absolute basic amount required to parse an HTTP Request. The
6905 goal is to be able to split headers from request body before passing
6906 the data back to the other filters.
6909 *) Bring forward from 1.3.13 the config directory implementation
6912 *) install apxs if it is created
6915 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
6916 conversions. [William Rowe]
6918 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
6919 ap_add_output_filter(). [Jeff Trawick]
6921 *) Multiple build and configuration fixes
6924 -add datadir and localstatedir substitutions
6926 -fix logfilename misspelling
6927 -fix evaluation of installation dir variables and
6928 -replace $foobar by $(foobar) to be usefull in the makefile
6932 -add rules for cross-compiling in rules.mk. Okay, rule to check for
6933 $CC_FOR_BUILD is still missing
6934 -use CHECK_TOOL instead of CHECK_PROG for ranlib
6935 -add missing "AR=@AR@" to severaly Makefile.in's
6936 -cache result for "struct rlimit"
6937 -compile all helper programs with native and cross compiler
6938 and use the native version to generate header file
6939 [Rüdiger Kuhlmann <Tadu gmx.de>]
6941 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
6943 [Rüdiger Kuhlmann <Tadu gmx.de>]
6945 *) Fix a bug where a client which only sends \n to delimit header
6946 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
6947 message. Start working on ebcdic co-existance with input
6949 [William Rowe, Greg Ames]
6951 *) If mod_so is enabled in the server always create libexec, even
6952 if there are no modules installed in this directory. This is a
6953 requirement for APXS to work correctly.
6956 *) Connection oriented output filters are now stored in the
6957 conn_rec instead of the request_rec. This allows us to add the
6958 output filter in the pre-connection phase instead of the
6959 post_read_request phase, which keeps us from trying to write an
6960 error page before we have a filter to write to the network.
6961 [Ryan Bloom, Jeff Trawick, and Greg Ames]
6963 *) Cleaning up an mmap bucket no longer deletes the mmap. An
6964 mmap can be used across multiple buckets (default_handler with
6965 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
6966 the mmap itself can't be associated with the bucket.
6969 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
6972 *) Radical surgery to improve mod_isapi support under Win32.
6973 Includes a number of newer ServerSupportFunction calls, support
6974 for ReadClient (in order to retrieve POSTs greater than 48KB),
6975 and general bug fixes to more reliably load ISAPI .dll's and
6976 prevent leaking handle resources. Note: There are still
6977 discrepancies between IIS's and Apache's ServerVariables, and
6978 async calls are still not supported. Additional warnings are
6979 logged to facilitate debugging of unsupported ISAPI calls.
6982 *) Add input filtering to Apache. The basic idea for the input
6983 filters is the same as the ideas for output filters. The biggest
6984 difference is that instead of calling ap_pass_brigade, ap_get_brigade
6985 should be called, and the order of execution for the filter itself is
6986 different. When writing an output filter, a brigade is passed in,
6987 and filters operate directly on that brigade, when done, they call
6988 ap_pass_brigade. Input filters are the exact opposite. Because input
6989 is not a push operation, filters first call ap_get_brigade. When this
6990 function returns, the input filter will be left with a valid brigade.
6991 The input filter should then operate on the brigade, and return.
6994 *) Fix building on BSD/OS using its native make. The build system
6995 falls back to the BSD .include directive on that host platform.
6998 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
6999 SHA1 and plaintext password encodings. Make feature tests a
7000 bit more flexible. [William Rowe]
7002 *) Charset translation: mod_charset_lite handles output content
7003 translation in a filter. mod_charset_lite no longer ignores
7004 subrequests. A bunch of cruft related to BUFF's support for
7005 translating request and response bodies was removed.
7008 *) Move the addition of the CORE filter to the post_read_request
7009 hook in http_core.c. This removes the need to add the filter in
7010 multiple places and allows for an SSL module to be added much
7011 simpler. [Ryan Bloom]
7013 *) SECURITY: CVE-2000-0913 (cve.mitre.org)
7014 Fix a security problem that affects certain configurations of
7015 mod_rewrite. If the result of a RewriteRule is a filename that
7016 contains expansion specifiers, especially regexp backreferences
7017 $0..$9 and %0..%9, then it may be possible for an attacker to
7018 access any file on the web server. [Tony Finch]
7020 *) Fix a bug where errors that are detected during early request parsing
7021 don't produce visible HTTP error messages at the browser, because
7022 the core_filter wasn't present. [Greg Ames]
7024 *) Provide apr_socklen_t as a portability aid.
7025 [Victor J. Orlikowski]
7027 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
7028 as well as a comment arg to the add, adduser and update cmds.
7029 update allows the user to clear or preserve pw/groups/comment.
7030 Fixed a bug in dbmmanage that prevented the check option from
7031 parsing a password followed by :group... text. Corrected the
7032 seed calcualation for Win32 systems, and added -lsdbm support.
7035 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
7038 *) Avoid a segfault when parsing .htaccess files. An
7039 uninitialized tree pointer was passed to ap_build_config().
7042 *) Change the way that inet_addr & inet_network are checked for
7043 in APR's configure process to allow BeOS BONE to correctly
7044 find them. With this change BeOS BONE now builds from source
7045 with no problems. [David Reid]
7047 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
7048 the end of the parameters to execve() was stored in the wrong
7049 location, overlaying the storage beyond the newargs[] array and
7050 also passing uninitialized storage to execve(), which would
7051 sometimes fail with EFAULT. [Jeff Trawick]
7053 *) Fix a bug parsing configuration file containers. With a sequence
7054 like this in the config file
7056 <IfModule mod_kilroy.c>
7059 <IfModule mod_lovejoy.c>
7064 the second container would be terminated at the blank line due to
7065 sediment in the buffer from reading the prior </IfModule> and an
7066 error message would be generated for the real </IfModule> for the
7067 second container. Also due to this problem, any two characters
7068 could be used for "</" in the close of a container.
7071 *) ap_add_filter prototype changed to remove the ctx pointer. The
7072 pointer still remains in the filter structure, but it can not be
7073 a part of the ap_add_filter prototype. The reason is that when
7074 the core uses AddFilter to add a filter to the stack it doesn't
7075 know how to allocate the ctx pointer, or even how much memory should
7076 be allocated. The filters will have to be responsible for allocating
7077 the ctx memory when they need it.
7080 *) Add an AddFilter directive. This directive takes a list of filters
7081 that should be activated for the requested resource.
7084 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
7085 some other platforms). [Jeff Trawick]
7087 *) Modify mod_include to be a filter. Currently, it has only been tested
7088 on actual files, but it should work for CGI scripts too.
7091 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
7092 writes. apr_flush() for Unix: handle interrupted writes.
7095 *) NameVirtualHost can now take "*" as an argument instead of
7096 an IP address. This allows you to create a purely name-based
7097 virtual hosting server that does not have any IP addresses in
7098 the configuration file and which ignores the local address
7099 of any connections. PR #5595, PR #4455 [Tony Finch]
7101 *) Fix some compile warnings in mod_mmap_static.c
7102 [Mike Abbott <mja sgi.com>]
7104 *) Fix chunking problem with CGI scripts. The general problem was that
7105 the CGI modules were adding an EOS bucket and then the core added an
7106 EOS bucket. The chunking filter finalizes the chunked response when it
7107 encounters an EOS bucket. Because two EOS buckets were sent, we
7108 finalized the response twice. The fix is to make sure we only send one
7109 EOS, by utilizing a flag in the request_rec.
7112 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
7113 and Win32. Previously, the first read from an apr_file_t set up via
7114 apr_put_os_file() would return a '\0'. [Jeff Trawick]
7116 *) Mod_cgid now creates a single element bucket brigade, with a pipe
7117 bucket, instead of using BUFF's and ap_r*.
7120 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
7121 [Mike Abbott <mja sgi.com>]
7123 *) Remove ap_bopenf from buff code. This required modifying the file_cache
7124 code to use APR file's directly instead of going through BUFFs.
7127 *) Fix compile break on some platforms for mod_mime_magic.c
7128 [John K. Sterling <sterling covalent.net>]
7130 *) Fix merging of AddDefaultCharset directive.
7131 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
7133 *) Minor revamp of the rlimit sections of code. We now test
7134 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
7135 is now "available" even if the platform doesn't support
7136 the rlimit family (it's just a noop though). [Jim Jagielski]
7138 *) Migrate the pre-selection of which MPM to use for specific
7139 platforms to hints.m4, which contains (or should contain)
7140 all platform specific "hints". [Jim Jagielski]
7142 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
7145 *) Add tables with non-string/binary values to APR.
7148 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
7151 *) Update PCRE to version 3.2. [Ryan Bloom]
7153 *) Change the way buckets' destroy functions are called so that
7154 they can be more directly used when changing the type of a
7155 bucket in place. [Tony Finch]
7157 *) Add generic support for reference-counting the resources used by
7158 buckets, and alter the HEAP and MMAP buckets to use it. Change
7159 the way buckets are initialised to support changing the type of
7160 buckets in place, and use it when setting aside TRANSIENT buckets.
7161 Change the implementation of TRANSIENT buckets so that it can be
7162 mostly shared with IMMORTAL buckets, which are now implemented.
7165 Changes with Apache 2.0a6
7167 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
7169 *) Add a chunking filter to Apache. This brings us one step closer
7170 to removing BUFF. [Ryan Bloom]
7172 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
7173 added to the stack is the last filter to be called. [Ryan Bloom]
7175 *) Apache 2.0 has been completely documented using Scandoc. The
7176 docs can be generated by running 'make docs'. [Ryan Bloom]
7178 *) Add filtered I/O to Apache. This is based on bucket brigades,
7179 Currently the buckets still use BUFF under the covers, but that
7180 should change quickly. The only currently written filter is the
7181 core filter which just calls ap_bwrite. [The Apache Group]
7183 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
7184 built with thread support. [Jeff Trawick]
7186 *) Abort configuration if --with-layout was specified and there's
7187 no layout definition file. [Ken Coar]
7189 *) Add support for '--with-port=n' option to configure. [Ken Coar]
7191 *) Add support for extension methods for the Allow response header
7192 field, and an API routine for accessing r->allowed and the
7193 list of extension methods in a unified manner. [Ken Coar]
7195 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
7196 [Rob Simonson <simo us.ibm.com>]
7198 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
7199 APACHE_XLATE builds. [Jeff Trawick]
7201 *) A configuration file parsing problem was fixed. When the
7202 configuration file started with an IfModule/IfDefine container,
7203 only the last statement in the container would be retained.
7206 Changes with Apache 2.0a5
7208 *) Perchild is serving pages after passing them to different child
7209 processes. There are still a lot of bugs, but this does work. I
7210 have made requests against the same installation of Apache, and had
7211 different servers use different user IDs to serve the responses.
7212 This change moves to using socketpair instead of an AF_UNIX socket.
7215 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
7216 It can't seem to pass between child processes yet, but I think we
7217 are closer now than before. This moves us back to using Unix
7218 Domain Sockets. [Ryan Bloom]
7220 *) libapr functions and types renamed with apr_ prefix.
7221 #include "apr_compat.h" for 1.3.x backwards compat
7224 *) Fix problems with APR sockaddr handling on Win32. It didn't always
7225 return the right information on the local socket address.
7226 [Gregory Nicholls <gnicholls level8.com>]
7228 *) ap_recv() on Win32: Set bytes-read to 0 on error.
7229 [Gregory Nicholls <gnicholls level8.com>]
7231 *) Add an option to not detach from the controlling terminal without
7232 going into single process mode. This allows for much easier
7233 debugging of the process startup code. [Ryan Bloom]
7235 *) ab: don't use perror() to report the failure of an APR function.
7238 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
7239 scoreboard on graceful restarts.
7242 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
7243 An invalid ap_proc_t was passed to ap_create_process().
7246 *) Allow modules to register filters. Those filters are still
7247 never called, but this is a step in the right direction.
7248 [Ryan Bloom and Greg Stein]
7250 *) Register the mod_cgid daemon process for cleanup so that it is
7251 killed at termination if it does not die when the parent gets
7252 SIGTERM. This change is to fix occasional problems where the
7253 process stays around. Bugs in similar logic in mod_rewrite and
7254 mod_include were also fixed. [Jeff Trawick]
7256 *) Fix a bug in the time handling. Basically, we were imploding a time
7257 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
7258 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
7259 uses those two fields to adjust the time value. Because of the HTTP
7260 spec, both of those values can be zero'ed out safely. This fixes
7261 the bug correctly. [Ryan Bloom]
7263 *) Fix a couple of place in the Windows code where the wrong error
7264 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
7266 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
7268 *) Added the APR_EOL_STR macro for platform dependent differences in
7269 logfiles and other raw text (such as all APR files). Fixes logfiles
7270 not terminated with cr/lf sequences in Win32. [William Rowe]
7272 *) Move all strings functions in APR to src/lib/apr/strings and create
7273 apr_strings.h for the prototypes. [Ryan Bloom]
7275 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
7276 to repeat the syscall until we stop getting EINTR. I noticed a
7277 related problem at termination (SIGTERM) on FreeBSD when using
7278 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
7279 implementation work properly with child init. Previously, ap_lock()
7280 was essentially a no-op because all children were using different
7281 locks and thus nobody ever blocked. [Jeff Trawick]
7283 *) The htdocs/ tree has been moved out of the CVS source tree into
7284 a separate area for easier development. This has NO EFFECT on
7285 end-users or Apache installations. [Ken Coar]
7287 *) Integrate the mod_dav module for WebDAV protocol handling. This
7288 adds the dav and dav_fs modules, the SDBM library, and additional
7289 XML handling utilities. [Greg Stein]
7291 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
7294 *) Update the lib/expat-lite/ library (bring forward changes from
7295 the Apache 1.3 repository). [Greg Stein]
7297 *) If sizeof(long long) == sizeof(long), then prefer long in APR
7298 configure.in. [Dave Hill <ddhill zk3.dec.com>]
7300 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
7301 machines where sendfile is detected, but nobody has written ap_sendfile.
7302 [Dave Hill <ddhill zk3.dec.com>]
7304 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
7306 *) ab would start up more connections than needed, then quit when the
7307 desired number were finished. Also fixed a logic error involving
7308 ab keepalives. [Victor J. Orlikowski]
7310 *) WinNT: Implement non-blocking pipes with timeouts to communicate
7311 with CGIs. Apache 2.0a4 had non-blocking pipes but without
7312 timeouts (i.e, if a timeout was specified, the pipe reverted to
7313 a full blocking pipe). Now the behaviour is more in line with
7314 Unix non-blocking pipes.
7317 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
7318 cache open file handles along with accept socket reuse enables
7319 Apache 2.0 to serve non-keepalive requests for static files at
7320 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
7321 and Apache 2.0 will serve almost 1200 rps on my system).
7324 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
7325 supports two config directives, mmapfile (same behavious as
7326 mod_mmap_static) and cachefile. Use the cachefile directive
7327 to cache open file handles. This directive only works on systems
7328 that have implemented the ap_sendfile API. cachefile works today
7329 on Windows NT, but has not been tested on any flavors of Unix.
7332 *) Cleanup the configuration. With the last few changes the
7333 configuration process automatically:
7334 inherits information about how to build from APR. Allowing
7335 APR to inform Apache that it should or should not use -ldl
7337 Detects which mod_cgi should be used mod_cgi or mod_cgid,
7338 based on the threading model
7340 Apache calls APR's configure process before finishing it's
7341 configuration processing, allowing for more information flow
7346 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
7347 with non-zero argument makes the socket non-blocking. BeOS and
7348 OS/2 already worked this way. [Jeff Trawick]
7350 *) ap_close() now calls ap_flush() for buffered files, so write
7351 operations work a whole lot better on buffered files.
7354 *) Fix error messages issued from MPMs which explain where to change
7355 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
7358 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
7359 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
7360 now the way that the blocking state of a pipe is manipulated.
7361 ap_block_pipe() is gone. [Jeff Trawick]
7363 *) Correct the problem where the only local host name that the IP stack
7364 can discover are 'undotted' private names. If no fully qualified
7365 domain name can be identified, the default ServerName will be set to
7366 the machine's IP address string. A warning is always provided if the
7367 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
7369 *) Repair problems with config file processing which caused segfault
7370 at init when virtual hosts were defined and which caused ServerName to
7371 be ignored when there was no valid DNS setup. [Jeff Trawick]
7373 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
7375 *) Add ap_sendfile implementation for AIX
7376 [Victor J. Orlikowski]
7378 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
7379 apr_network_io.h, and apr_thread_proc.h.
7380 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
7382 *) Bring the allocation and pool debugging code back into a working
7383 state. This will need to be tested as so far it's only been used on
7386 *) Change configuration command setup to be properly typesafe when in
7387 maintainer mode. Note that this requires a compiler that can initialise
7388 unions. [Ben Laurie]
7390 *) Turn on buffering for config file reads. Part of this was to
7391 repair buffered I/O support in Unix and implement buffered
7392 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
7394 *) Win32: Fix problem where UTC offset was not being set correctly
7395 in the access log. Problem reported on news group by Jerry Baker.
7398 *) Fix segfault when reporting this type of syntax error:
7399 "</container> without matching <container> section", where
7400 container is VirtualHost or Directory or whatever.
7403 *) SECURITY: CVE-2000-1204 (cve.mitre.org)
7404 Prevent the source code for CGIs from being revealed when
7405 using mod_vhost_alias and the CGI directory is under the document root
7406 and a user makes a request like http://www.example.com//cgi-bin/cgi
7407 as reported in <news:960999105.344321 ernani.logica.co.uk>
7410 *) Add support for the new Beos NetwOrking Environment (BONE)
7413 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
7414 final input char is incomplete; ap_bwrite_xlate() now handles
7415 incomplete final input chars. [Jeff Trawick]
7417 *) Yet another update to saferead/halfduplex stuff -- need to ensure
7418 that a bhalfduplex call occurs before logging or else DNS and
7419 such can delay the last packet of the response. [Dean Gaudet]
7421 *) Some syscall reduction in APR on unix -- don't seek when setting
7422 up an mmap; and don't fcntl() more than once per socket.
7425 *) When mod_cgid is started as root, the cgi daemon now switches
7426 to the configured User/Group (like other httpd processes)
7427 instead of continuing as root. [Jeff Trawick]
7429 *) The prefork MPM now uses an APR lock for the accept() mutex.
7430 It has not been getting a lock at all recently. httpd -V now
7431 displays APR's selection of the lock mechanism instead of the
7432 symbols previously respected by prefork. [Jeff Trawick]
7434 *) Change the mmap() feature test to check only for existence.
7435 The previous check required features not used by Apache.
7438 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
7439 sometimes mangled. The len parm to accept() was not
7440 initialized, leading sometimes to an endless loop of failed
7441 accept() calls on OS/390 and anywhere else that failed the call
7442 if the len was negative. Use <sys/un.h> for struct sockaddr_un
7443 instead of declaring it ourselves to fix a compilation problem
7444 on Solaris. [Jeff Trawick]
7446 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
7448 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
7450 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
7452 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
7453 initialization if ALLOC_DEBUG is defined; no known symptom
7454 otherwise. [Jeff Trawick]
7456 *) Fix typo in configure script when checking for mod_so. bash
7457 doesn't seem to have a problem but /bin/sh on Solaris does.
7458 Symptom: "./configure: test: unknown operator =="
7461 *) Rebind the Win32 NT and 9x services control into the MPM.
7462 All console, WinNT SCM and Win9x pseudo-service control code is
7463 now wrapped within the WinNT MPM.
7466 *) Make a copy of getenv("PATH") before storing for later use. Some
7467 getenv() implementations use the same storage for successive calls.
7468 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
7470 *) Server Tokens work in 2.0 again. This also propogates the change
7471 to allow just the product name in the server string using
7475 Changes with Apache 2.0a4
7477 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
7478 won't need to call it. [Greg Ames, Jeff Trawick]
7480 *) Move pre_config hook call to between configuration read and config
7481 tree walk. This allows all modules to implement pre_config hooks
7482 and know that they will be called at an appropriate time.
7485 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
7488 *) Add pre-config hooks back to all modules.
7491 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
7492 ContentDigest enabled and we can't/don't mmap the file.
7495 *) We now report the correct line number for syntax errors in config
7496 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
7498 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
7499 related bugs, and changed shmem/locking to use apr API. Shared-mem
7500 is currently disabled, however, because of problems with graceful
7501 restarts. [Ronald Tschalär]
7503 *) Fix corruption of IFS variable in --with-module= handling.
7504 Depending on the user's shell or customization thereof, there
7505 would be errors generating ap_config_auto.h later in the configure
7506 procedure. [Jeff Trawick]
7508 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
7509 isn't used (as in 1.3), except that on Unix it is now logged via
7510 ap_log_rerror() instead of by the child having STDERR_FILENO refer
7511 to the error log. [Greg Ames, Jeff Trawick]
7513 *) Add '-D' argument processing for run time configuration defines.
7516 *) Organize http_main.c as independent code, such that no code or
7517 global data is exported from it. WIN32 will dynamically link it
7518 to the server core, so this will prevent mutual dependency.
7521 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
7522 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
7525 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
7526 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
7528 *) Add mod_charset_lite for configuring character set translation.
7531 *) Add '-n' option to htpasswd to make it print its user:pw record
7532 on stdout rather than having to frob a text file. [Ken Coar]
7534 *) Fix saferead. Basically, we flush the output buffer if a read on the
7538 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
7539 a conversion is single-byte only. [Jeff Trawick]
7541 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
7542 the BeOS 5.0 documentation says that shutdown doesn't work yet.
7545 *) Fix some minor errors where pid was being manipulated as an int
7546 instead of the portable pid_t. [Roy Fielding]
7548 *) Fix some error log prints that were printing the pointer to a
7549 structure rather than the pid within the structure.
7550 [Jeff Trawick, Roy Fielding]
7552 *) ab: Fix a command-line processing bug; track bad headers in
7553 err_response; support reading headers up to 2K.
7554 [Ask Bjoern Hansen <ask valueclick.com>]
7556 *) Fix ap_resolve_env() so that it handles new function added in a prior
7557 alpha (see "Added the capability to do ${ENVVAR} constructs in the
7558 config file.") as well as the constructs used by mod_rewrite.
7559 [Paul Reder <rederpj raleigh.ibm.com>]
7561 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
7563 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
7564 APR to perform translation, instead of accessing the hard-coded tables
7565 in 1.3's ebcdic.c. [Jeff Trawick]
7567 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
7570 *) Add the ability to hook into the config file reading phase. Basically
7571 if a directive is specified EXEC_ON_READ, then when that directive is
7572 read from the config file, the assocaited function is executed. This
7573 should only be used for those directives that must muck with HOW the
7574 server INTERPRETS the config. This should not be used for directives
7575 that re-order or replace items in the config tree. Those changes should
7576 be made in the pre-config step.
7579 *) Add mod_example to the build system.
7582 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
7583 byte character sets. [Jeff Trawick]
7585 *) Pick up various EBCDIC fixes from 1.3 (from Martin
7586 Kraemer and Oliver Reh originally according to the change log).
7589 *) Fix a couple of problems in RFC1413 support (controlled by the
7590 IdentityCheck directive). Apache did not build the request string
7591 properly and more importantly Apache would loop forever if the
7592 would-be ident server dropped the connection before sending a
7593 properly terminated response. [Jeff Trawick]
7595 *) apxs works in 2.0.
7598 *) Reliable piped logs work in 2.0.
7601 *) Introduce a hash table implementation into APR to be used for
7602 replacing tables and other random data structures in Apache.
7605 *) Add some more error reporting to htpasswd in the case of problems
7606 generating or accessing the temporary file. Also, pass in a
7607 buffer if the implementation knows how to use it (i.e., if L_tmpnam
7608 is defined). [Ken Coar]
7610 *) Configure creates config.nice now containing your configure
7611 options. Syntax: ./config.nice [--more-options]
7614 *) Fix various return code problems in APR on Win32. For most of
7615 these, APR was returning APR_EEXIST instead of GetLastError()/
7616 WSAGetLastError(). [Jeff Trawick]
7618 *) Make piped logs work again in version 2.0
7621 *) Add VPATH support to UNIX build system of Apache and APR.
7624 *) Fix ap_tokenize_to_argv to respect the const arguments that are
7628 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
7629 Patch submitted to author.
7632 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
7633 /sbin in PATH on FreeBSD (all submitted to rse previously)
7636 *) Fix building Pthread-based MPMs on OpenBSD
7637 [Sascha Schumann] PR#26
7639 *) Fix ap_readdir() problem on systems where d_name[] field in
7640 struct dirent is declared with only one byte. (This problem only
7641 affected multithreaded builds.) This caused a segfault during
7642 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
7643 least). [Jeff Trawick]
7645 *) Fix some make-portability problems on at least Tru64, Irix
7647 [Sascha Schumann] PR#18, PR#39
7649 *) Add ap_sigwait() to support old-style sigwait() on systems
7650 like OS/390 and UnixWare.
7653 *) Add POSIX-thread flags for more platforms.
7656 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
7657 (on Unix, at least) to handle resolver errors. Fix a bug in
7658 the definition of APR_ENOMEM so that ap_strerror() can spit
7659 out the correct error message for it.
7662 Changes with Apache 2.0a3
7664 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
7667 *) API: *HOOK* macros now have an AP_ prefix
7670 *) Win32: Eliminate redundant calls to initialize winsock.
7671 [Tim Costello <timcostello ozemail.com.au>]
7673 *) Fix bugs initializing ungetchar for pipes.
7674 [Chia-liang Kao <clkao CirX.ORG>]
7676 *) The ab program in the src/support directory is now portable using
7680 *) Support directory is being compiled when the server is built
7683 *) The configure option --with-program-name has been added to allow
7684 developers to rename the executable at configure time. This also
7685 changes the name of the config files to match the executable's name.
7688 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
7689 containing version numbers. [Martin Pool]
7691 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
7692 Unix; access_log and error_log now created with these perms; non-
7693 Unix is unaffected [Jeff Trawick]
7695 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
7696 Replaced more magic numbers with MD5_DIGESTSIZE.
7697 [William Rowe, Roy Fielding]
7699 *) Win32: Get mod_auth_digest compiling and added to the Windows
7700 build environment. Not tested and I'd be suprised if it
7701 actually works. [Bill Stoddard]
7703 *) Revamp the Win32 make environment. Makefiles have been removed and
7704 Apache.dsw created to bring together all the pieces. Create new file
7705 os/win32/BaseAddr.ref to define module base addresses (to prevent
7706 dll relocation at start-up).
7707 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
7709 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
7710 of the \015, \012, and \015\012 constants with macros.
7713 *) Add ap_xlate_open() et al for translation of text between different
7714 character sets. The initial implementation requires iconv().
7717 *) More FAQs and answers from comp.infosystems.www.servers.unix.
7718 [Joshua Slive <slive finance.commerce.ubc.ca>]
7720 *) CGI output is being timed out now.
7723 *) Fix the problem with dieing quietly. dupfile now takes a pool which
7724 is used by the new apr file. There is no reason to create a new file
7725 with the same lifetime as the original file.
7728 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
7729 module base addresses. This will help shooting seg faults
7730 in the field. [William Rowe <wrowe lnd.com>]
7732 *) Update Apache on Windows documentation. Add new document
7733 describing how to compile Apache on Windows.
7734 [William Rowe <wrowe lnd.com>]
7736 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
7737 microseconds instead of seconds. Some storage leaks and other
7738 minor bugs in related code were fixed. [Jeff Trawick]
7740 *) Win32: First cut at getting mod_isapi working under 2.0
7741 [William Rowe <wrowe lnd.com>]
7743 *) First stab at getting mod_auth_digest working under 2.0
7744 quick change summary:
7745 - moved the random byte generation (ap_generate_random_bytes) into APR
7746 - now uses ap_time_t
7747 - compiles and runs on linux
7749 [Brian Martin <bmartin penguincomputing.com>]
7751 *) Win32: Move the space stripping of physical service names
7752 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
7753 unresolved symbol. Add dependency checking to the
7754 CreateService call to ensure TCPIP and AFP (winsock) is started
7756 [William Rowe <wrowe lnd.com>]
7758 *) Win32: Add code to perform latebinding on functions that may
7759 not exist on all levels of Windows where Apache runs. This
7760 is needed to allow Apache to start-up on Win95/98. All calls
7761 to non portable functions should be protected with
7762 ap_oslevel checks to prevent runtime segfaults.
7763 [William Rowe <wrowe lnd.com>]
7765 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
7767 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
7769 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
7770 This addresses PR 1623. Still need to address timing out runaway
7771 CGI scripts. [Bill Stoddard]
7773 *) Win32: Make ap_stat Windows 95/98 friendly
7774 [William Rowe <wrowe lnd.com>]
7776 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
7777 always fail. Need to initialise the dwOSVersionInfoSize member of the
7778 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
7781 The patch also enhances ap_get_oslevel (and the associated enum) to
7782 handle selected service packs for NT4, and adds recognition for
7783 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
7784 we can use ReadFileScatter and WriteFileGather in readwrite.c.
7785 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
7787 *) Get mod_rewrite building and running, and mod_status building for Win NT
7788 [Allan Edwards <ake raleigh.ibm.com>]
7790 *) Patch to port mod_auth_db to the 2.0 api and also to support
7791 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
7792 2.7.7. It should work with version 1 as well but I haven't tested it.
7793 [Brian Martin <bmartin penguincomputing.com>]
7795 *) Get APR DSO code working under Windows. Includes cross platform
7797 [<Tim.Costello BTFinancialgroup.com>]
7799 *) Fix some of the Windows APR time functions.
7802 *) FAQ changes related to tidying up historical documents on the web site.
7803 [Joshua Slive <slive finance.commerce.ubc.ca>]
7805 *) Move Windows DSO code into APR.
7808 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
7809 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
7810 at build time. At this point, the server will not compile on Windows because
7811 of the recent DSO commits. Fixing those next.
7812 [Bill Rowe & Bill Stoddard]
7814 *) Added error checking for file I/O APR routines.
7815 [Jon Travis <jtravis covalent.net>]
7817 *) APR: Don't use the values of resolver error codes for the
7818 corresponding APR error codes. On Unix and Win32, return the
7819 proper APR error code after a resolver error. [Jeff Trawick]
7821 Changes with Apache 2.0a2
7823 *) Renamed the executable back to httpd on all platforms other
7827 *) Allow BeOS to survive restarts, log properly and a few
7828 small things it had problems with due to the way it setup
7829 users and groups. [David Reid]
7831 *) Get mod_rewrite working with APR locks
7832 [Paul Reder <rederpj raleigh.ibm.com>]
7834 *) Actually remove the sempahore when the lock cleanup routine
7835 is called on BeOS. [David Reid]
7837 *) Clear hook registrations between reads of the config file.
7838 When DSOs are unloaded and re-loaded the old hook pointers may
7839 no longer be valid. This fix eliminates potential segfaults.
7840 [Allan Edwards <ake raleigh.ibm.com>]
7842 *) Fix a problem with Sigfunc not being defined or bypassed
7843 if sigaction() wasn't found. [Jim Jagielski]
7845 *) Fix the locking mechanism on BSD variants. They now use fcntl
7846 locks. This allows the server to start and serve pages.
7849 *) First cut at getting the Win32 installer to work
7850 [William Rowe <wrowe lnd.com>]
7852 *) Get htpasswd compiling under Windows
7853 [William Rowe <wrowe lnd.com>]
7855 *) Change the log message for a bind() failure to show the
7856 interface and port number. [Jeff Trawick]
7858 *) Import the documentation from 1.3.12 and bring parts of it
7859 up-to-date with respect to the changes that have occurred
7863 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
7864 now logged correctly on BeOS.
7867 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
7868 Makefile.win includes the same user interface as the old
7870 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
7872 *) Win32 exec now uses COMSPEC environment string for command
7873 shell path resolution.
7874 [William Rowe <wrowe lnd.com>] PR#3715
7876 *) Win32: ap_connect() was not returning correct error condition
7878 [Allen Prescott <allen clanprescott.com>]
7880 *) Win32: ap_open() was broken on Win9x because an NT-specific
7881 flag was passed to CreateFile. ap_puts() added an unnecessary
7883 [Jeff Trawick <trawick us.ibm.com>]
7885 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
7886 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
7887 confusing ee/et name and made all extensions language/dialect
7888 rather than country reflecting. Changed example files to
7889 explicit reflect the ISO charset and added a few common
7890 ones to the example config [dirkx]
7892 *) Extend external module capability. To use this, you call
7893 configure with --with-module=path/to/mod1,path/to/mod2,etc.
7896 *) Backported the various "default charset" fixes from 1.3.12,
7897 including the AddDefaultCharset directive. [Jim Jagielski]
7899 *) Added the capability to do ${ENVVAR} constructs in the
7900 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
7901 it does this on a line by line basis; i.e. if the envvar
7902 expands to something with spaces you have to protect it
7903 by adding quotes around it (Unless of course you expect it
7904 to contains more than one argument. Alternatively you
7905 can compile it on a per token basis; which is what people
7906 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
7907 hampers fancier hacks.
7908 [Dirk-Willem van Gulik]
7910 *) Changed the 'ErrorDocument' syntax in that it NO longer
7911 supports the asymetric
7913 ErrorDocument 301 "Some message
7915 Note the opening " quote, without a closing quote. It now
7916 has either the following syntaxes
7918 ErrorDocument XXX /local/uri
7919 ErrorDocument XXX http://valid/url
7920 ErrorDocument XXX "Some Message"
7922 The recognition heuristic is: if it has a space it
7923 is a message. If it has no spaces and starts with a /
7924 or is a valid URL then treat it that way. Otherwise it
7925 is assumed to be a message.
7927 This breaks backward compatibility but makes live a hell
7928 of a lot easier for GUI's and config file parsers.
7929 [Dirk-Willem van Gulik]
7931 *) Changed 'CacheNegotiatedDocs' from its present/not-present
7932 syntax into a 'on' or 'off' syntax. As it currently is the
7933 only non nesting token which uses NO_ARGS and thus is an
7934 absolute pain for any config interface automation. This
7935 breaks backward compatibility. [Dirk-Willem van Gulik]
7937 *) Add ability to add external modules to the build process. This is
7938 done with --with-module=/path/to/module. Modules can only be added
7939 as static modules at this point.
7942 Changes with Apache 2.0a1
7944 *) Fix FreeBSD 3.3 core dump.
7945 Basically, ap_initialize() needs to get called before
7946 create_process(), since create_process() passes op_on structure
7947 to semop() to get a lock, but op_on isn't initialized until
7948 ap_initialize() calls setup_lock(). Here is a slight
7949 rearrangement to main() which calls ap_initialize() earlier...
7950 [Jeff Trawick <trawick us.ibm.com>]
7952 *) Enable Apache to use sendfile/TransmitFile API
7953 [Bill Stoddard, David Reid, Paul Reder]
7955 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
7959 *) Make file I/O and network I/O writev/sendv APIs consistent.
7960 Eliminate use of ap_iovec_t and use Posix struct iovec.
7961 Use seperate variable on ap_writev to set the number of iovecs
7962 passed in and number of bytes written.
7965 *) Adapt file iol to use APR functions. Replaced ap_open_file()
7966 with ap_create_file_iol(). ap_create_file_iol() requires that
7967 the file be opened prior to the call using ap_open().
7970 *) Port mod_include and mod_cgi to 2.0
7971 [Paul Reder, Bill Stoddard]
7973 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
7974 bytes_read/bytes_written is always valid (never -1). Plus
7975 some fixes to buff.c to correct problems introduced by the
7976 errno => ap_status_t changes a while back. Plus a fix to
7977 chunked encoding introduced right at the beginning of 2.0.
7980 *) Revamped UNIX build system to use autoconf and libtool.
7981 [Manoj Kasichainula, Sascha Schumann]
7983 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
7985 *) SECURITY: More rigorous checking of Host: headers to fix security
7986 problems with mass name-based virtual hosting (whether using mod_rewrite
7987 or mod_vhost_alias).
7988 [Ben Hyde, Tony Finch]
7990 *) Add back support for UseCanonicalName in <Directory> containers.
7991 [Manoj Kasichainula]
7993 *) Added APLOG_STARTUP log type. This allows us to write an error
7994 message without any of the date and time information. As a part
7995 of this change, I also removed all of the calls to fprintf(stderr
7996 and replaced them with calls to ap_log_error using APLOG_STARTUP
7997 writing to stderr is no longer portable, because we don't direct
7998 stderr to the error log on all platforms.
8001 *) Convert error logging functions to take errno as an argument.
8002 This makes our error logs more portable, because some Windows API's
8003 don't set errno. This change allows us to still output a valid
8004 message on all of our platforms.
8007 *) mod_mime_magic runs in 2.0-dev now.
8008 [Paul Reder <rederpj raleigh.ibm.com>]
8010 *) sendfile has been added to APR.
8011 [John Zedlewski <zedlwski Princeton.EDU>]
8013 *) buff.c has been converted to no longer use errno.
8014 [Manoj Kasichainula]
8016 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
8017 interface adaption to APR functions did it. [Martin Kraemer]
8019 *) Support DSOs properly on 32-bit HP-UX 11.0
8020 [Dilip Khandekar <dilip cup.hp.com>]
8022 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
8023 [Ralf S. Engelschall]
8025 *) Cleaned APR build environment integration and bootstrap APR
8026 automatically for developers from src/Configure.
8027 [Ralf S. Engelschall]
8029 *) Fixed building of src/support/htpasswd.c
8030 [Ralf S. Engelschall]
8032 *) When generating the Location: header, mod_speling forgot
8033 to escape the spelling-fixed uri. (Forw-Port from 1.3)
8036 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
8038 *) Change all pools to APR contexts. This is the first step to
8039 incorporating APR into Apache. [Ryan Bloom]
8041 *) Move "handler not found" warning message to below the check
8042 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
8043 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
8045 *) Support line-continuation feature in config.option file and
8046 allow the loading of multiple option sections at once via
8047 ``--with-option=<section1>,<section2>,...''
8048 [Ralf S. Engelschall]
8050 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
8052 Changes with Apache MPM
8054 *) Use asynchronous AcceptEx() and a completion port to accept and
8055 dispatch connections to threads in Windows NT/2000.
8058 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
8061 *) Implement the APACI --with-option facility
8062 (per default used the config.option file).
8063 [Ralf S. Engelschall]
8065 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
8067 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
8068 Replace pre_connection module call with a register_hook call and
8069 implement pre_connection as a hook. The intent is that these hooks will
8070 be extended to allow Apache to be multi-protocol, and also to allow the
8071 calling order to be specified on a per-hook/per-module basis.
8074 *) Implement mpm_* methods as "modules". Each method gets its own
8075 subdir in src/modules (eg: src/modules/prefork). Selection
8076 of method uses Rule MPM_METHOD. [Jim Jagielski]
8078 *) Port the hybrid server from the apache-apr repository as
8079 mpm_mpmt_pthread. [Manoj Kasichainula]
8081 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
8082 amongst the unix MPMs.
8084 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
8085 signal handling for the new world order. [Dean Gaudet]
8087 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
8088 of alloc.c for now. [Dean Gaudet]
8090 *) Handle partial large writes correctly. [Ben Laurie]
8092 *) Eliminate conn_rec's pointer to server. All it knows is the base server
8093 based on IP/port. [Ben Laurie]
8095 *) Port a bunch of modules to the new module structure.
8096 ["Michael H. Voase" <mvoase midcoast.com.au>]
8098 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
8100 *) Basic restructuring to introduce the MPM concept; includes various
8101 changes to the module API... better described by
8102 docs/initial_blurb.txt. [Dean Gaudet]
8104 Changes with Apache pthreads
8106 *) New buff option added: BO_TIMEOUT. It describes the timeout for
8107 buff operations (generally over a network).
8108 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
8110 *) Created http_accept abstraction. Added 4 new functions (not exported):
8111 init_accept(), begin_accepting_requests(), get_request(),
8112 stop_accepting_requests() [Bill Stoddard]
8114 *) Fix to ap_rprintf call that allows mod_info to work properly.
8115 [James Morris <jmorris intercode.com.au>]
8117 *) user and ap_auth_type fields were moved from connection_rec to
8118 request_rec. [Ryan Bloom]
8120 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
8121 needed in a threaded server.
8123 *) Initial pthread implementation from from Dean's apache-nspr code.
8124 [Bill Stoddard, Ryan Bloom]
8127 Changes with Apache 1.3.9
8129 *) Remove bogus error message when a redirect doesn't set Location.
8130 Instead, use an empty string to avoid coredump if the error message
8131 was supposed to include a location. [Roy Fielding]
8133 *) Don't allow configure to include mod_auth_digest unless it is
8134 explicitly requested, even if the user asked for all modules.
8137 *) Translate module names to dll names for OS/2 so that they are no more
8138 than 8 characters long and have an extension of "dll" instead of "so".
8141 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
8142 Fix test-compile check to check for randbyte instead of trand32.
8143 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
8144 and tweak to make Amaya happier. [Ronald Tschalär]
8146 *) Ensure that the installed expat include files are world readable,
8147 just like the other header files. [Martin Kraemer]
8149 *) Fixed generated AddModule adjustments in APACI's `configure' script
8150 in order to allow (new) modules like mod_vhost_alias to be handled
8151 correctly (which was touched by the adjustments for mod_alias).
8152 [Ralf S. Engelschall]
8154 *) For binary builds, add -R flag to apachectl to work around the lack of
8155 an absolute path to the ./libexec directory where the libhttp.ep file
8156 is needed for SHARED_CORE architectures. [Randy Terbush]
8158 *) WIN32: Create the CGI script process as DETACHED. This may solve the
8159 problem observed by some Win95/98 users where they get CGI script
8160 output sent to the console. [Bill Stoddard]
8162 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
8163 routines are now called ap_base64* and are 'plain' (i.e., no
8164 pool access or anything clever). Inside util.c the routines acting
8165 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
8166 The oddly named ap_uuencode(), ap_uudecode() are kept around for
8167 now but deprecated. [dirkx]
8169 *) Clean up the base64 and SHA1 additions and make sure they are
8170 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
8171 files. [Roy Fielding]
8173 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
8174 checking. Allow compiling on VS 6.0. [Randy Terbush]
8176 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
8178 *) Use TestCompile to search for the truerand library (rather than blindly
8179 assuming its existence). If it is not found, complain (but do not
8180 exit - yet). [Martin Kraemer]
8182 *) We forgot to add the new exported function names to
8183 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
8185 *) Add description of -T command-line option to usage().
8186 [Ralf S. Engelschall]
8188 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
8189 searched only AFTER libap has been searched, because libap needs
8190 some symbols from libos. [Martin Kraemer]
8192 *) Fix conflict with original mod_digest related to the symbol of the
8193 module dispatch list (which has to be unique for DSO and follow the
8194 usual conventions for the installation procedure).
8195 [Ralf S. Engelschall]
8197 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
8198 for other platforms as well. [Martin Kraemer]
8200 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
8201 types by AP_LONG and replace reference to renamed variable 'ubuf'
8202 by 'buffer'. [Martin Kraemer]
8204 Changes with Apache 1.3.8 [not released]
8206 *) Flush the output buffer immediately after sending an error or redirect
8207 response, since the result may be needed by the client to abort a
8208 long data transfer or restart a series of pipelined requests.
8209 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
8211 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
8212 [Ian Turner <iant sequent.com>] PR#4735
8214 *) Local struct mmap in http_core.c conflicted with system structure
8215 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
8217 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
8218 [Ronald Tschalär <ronald innovation.ch>]
8220 *) Fix a memory leak where the module counts were getting messed
8221 up across restarts. [David Harris <dharris drh.net>]
8223 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
8224 properly in mod_access.
8225 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
8227 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
8228 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
8230 *) PORT: Support for compaq/tandem/com.
8231 [Michael Ottati <michael.ottati compaq.com>, dirkx]
8233 *) Added SHA1 password encryption support to easy migration from
8234 Netscape servers. See support/SHA1 for more information.
8235 Caused the separation of ap_md5.c into md5, sha1 and a general
8236 ap_checkpass.c with just a validate_passwd routine. Added a
8237 couple of flags to support/htpasswd. Some reuse of the to64()
8238 function; hence renamed to ap_to64().
8239 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
8241 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
8242 with ASCII/EBCDIC conversions in "ident" query.
8243 [David McCreedy <McCreedy us.ibm.com>]
8245 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
8246 Change "Power Macintosh" to Power* so if uname prints "Power Book"
8247 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
8249 *) Fix SIGSEGV on some systems because the Vary fix below included
8250 a call to table_do with a variable argument list that was not
8251 NULL terminated. Replaced with better implementation. [Roy Fielding]
8253 Changes with Apache 1.3.7 [not released]
8255 *) The "Vary" response header field is now sanitised right before
8256 the header is sent back to the client. Multiple "Vary" fields
8257 are combined, and duplicate tokens (e.g., "Vary: host, host" or
8258 "Vary: host, negotiate, host, accept-language") are reduced to
8259 single instances. This is a better solution than the force-no-vary
8260 one (which is still valid for clients that can't cope with Vary
8261 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
8263 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
8265 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
8266 least on Linux and FreeBSD for now.
8269 *) Win32: More apache -k restart work. Restarts are now honored
8270 immediately and connections in the listen queue are -not- lost.
8271 This is made possible by the use of the WSADuplicateSocket()
8272 call. The listeners are opened in the parent, duplicated, then
8273 the duplicates are passed to the child. The original listen sockets
8274 are not closed by the parent across a restart, thus the listen queue
8276 [Bill Stoddard <stoddard raleigh.ibm.com>]
8278 *) Fix handling of case when a client has sent "Expect: 100-continue"
8279 and we are going to respond with an error, but get stuck waiting to
8280 discard the body in the pointless hope of preserving the connection.
8281 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
8283 *) Fix 'configure' to work correctly with SysV-based versions of
8284 'tr' (consistent with Configure's use as well). [Jim Jagielski]
8286 *) apxs: Add "-S var=val" option which allows for override of CFG_*
8287 built-in values. Add "-e" option which works like -i but doesn't
8288 install the DSO; useful for editing httpd.conf with apxs. Fix
8289 editing code so that multiple invocations of apxs -a will not
8290 create duplicate LoadModule/AddModule entries; apxs can now be
8291 used to re- enable/disable a module. [Wilfredo Sanchez]
8293 *) Win32: Update the server to use Winsock 2. Specifically, link with
8294 ws2_32.lib rather than wsock32.lib. This gives us access to
8295 WSADuplcateSocket() in addition to some other enhanced comm APIs.
8296 Win 95 users may need to update their TCP/IP stack to pick up
8297 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
8298 [Bill Stoddard <stoddard raleigh.ibm.com>]
8300 *) Win32: Redirect CGI script stderr (script debug info) into the
8301 error.log when CGI scripts fail. This makes Apache on Win32
8302 behave more like Unix.
8303 [Bill Stoddard <stoddard raleigh.ibm.com>]
8305 *) Fixed `httpd' usage display: -D was missing.
8306 [Ralf S. Engelschall] PR#4614
8308 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
8309 [Ralf S. Engelschall] PR#4561, PR#4562
8311 *) OS/2: Fix problem with accept lock semaphores where server would die with
8312 "OS2SEM: Error 105 getting accept lock. Exiting!"
8313 [Brian Havard] PR#4505
8315 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
8316 [Randy Terbush <randy covalent.net>]
8318 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
8319 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
8321 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
8322 command potentially _is_ GCC. [Ralf S. Engelschall]
8324 *) Fix apxs build issues on AIX
8325 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
8327 *) DocumentRoot Checking: Under previous versions, when Apache
8328 first started up, it used to do a stat of each DocumentRoot to
8329 see if it existed and was a directory. If not, then an error
8330 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
8331 does not exist, you will get error messages in error_log. If
8332 the '-t' command line option is used (to check the configuration)
8333 the check of DocumentRoot IS performed. An additional command
8334 line option, '-T', has been added if you want to avoid the
8335 DocumentRoot check even when checking the configuration.
8338 *) Win32: The query switch "apache -S" didn't exit after showing the
8339 vhost settings. That was inconsistent with the other query functions.
8340 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
8342 *) Win32: Changed behaviour of apache -k restart.
8343 Previously, the server would drain all connections in the stack's
8344 listen queue before honoring the restart. On a busy server, this
8345 could take hours. Now, a restart is honored almost immediately.
8346 All connections in Apache's queues are handled but connections in
8347 the stack's listen queue are discarded. Restart triggered by
8348 MaxRequestPerChild is unchanged.
8349 [Bill Stoddard <stoddard raleigh.ibm.com>]
8351 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
8352 the accept loop. Good for a 5% performance boost. Cleaned up
8353 parent/child process management code.
8354 [Bill Stoddard <stoddard raleigh.ibm.com>]
8356 *) Added ceiling on file size for memory mapped files.
8357 [John Giannandrea <jg meer.net>] PR#4122
8359 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
8360 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
8361 [Henri Gomez <gomez slib.fr>, Ralf S. Engelschall]
8363 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
8364 use this at least for Expat. [Ralf S. Engelschall]
8366 *) Allow .module files to specify libraries with Lib:.
8369 *) Allow SetEnvIf[NoCase] to test environment variables as well
8370 as header fields and request attributes. [Ken Coar]
8372 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
8373 content-types are "text/html;parameters". PR#4524 [Ken Coar]
8375 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
8376 never accepted into any standard, and it opens up certain DoS
8377 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
8379 *) TestCompile updated. We can now run programs and output the
8380 results during the Configure process. [ Jim Jagielski]
8382 *) The source is now quad (long long) aware as needed. Specifically,
8383 the Configure process determines the correct size of off_t and
8384 *void. When the OS/platform/compiler supports quads, ap_snprintf()
8385 provides for the 'q' format qualifier (if quads are not available,
8386 'q' is silently "demoted" to long). [Jim Jagielski]
8388 *) When the username or password fed to htpasswd is too long, include the
8389 size limit in the error message. Also report illegal characters
8390 (currently only ':') in the username. Add the size restrictions
8391 to the man page. [Ken Coar]
8393 *) Fixed the configure --without-support option so it doesn't result in
8394 an infinite loop. [Marc Slemko]
8396 *) Piped error logs could cause a segfault if an error occured
8397 during configuration after a restart.
8398 [Aidan Cully <aidan panix.com>] PR#4456
8400 *) If a "Location" field was stored in r->err_headers_out rather
8401 than r->headers_out, redirect processing wouldn't find it and
8402 the server would core dump on ap_escape_html(NULL). Check both
8403 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
8404 if Location isn't set. [Doug MacEachern, Ken Coar]
8406 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
8407 of the Expat 1.0.2 distribution. [Greg Stein]
8409 *) Replace regexec() calls with calls to a new API stub function
8410 ap_regexec(). This solves problems with DSO modules which use the regex
8411 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]
8413 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
8414 environment variables can be set according to the protocol version
8415 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
8417 *) Add DSO support for OpenStep (Mach 4.2) platform.
8418 [Ralf S. Engelschall, Rex Dieter <rdieter math.unl.edu>] PR#3997
8420 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
8421 [Jan Gallo <gallo pvt.sk>] PR#3690, PR#4373
8423 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
8424 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
8426 *) Better DSO flags recognition on NetBSD platforms using ELF.
8427 [Todd Vierling <tv pobox.com>] PR#4310
8429 *) Always log months in english format for %t in mod_log_config.
8430 [Petr Lampa <lampa fee.vutbr.cz>] PR#4366, 679
8432 *) Support for server-parsed and multiview-determined ReadmeName and
8433 HeaderName files in mod_autoindex. Removed the restriction on
8434 "/"s in ReadmeName and HeaderName directives since the *sub_req*
8435 routines will deal with the access issues. (It's now possible to
8436 have {site|group|project|customer|...} wide readmes and headers.)
8437 [Raymond S Brand <rsbx rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
8440 *) When stat() fails, don't assume anything about the contents of
8441 the struct stat. [Ed Korthof <ed bitmechanic.com>]
8443 *) It's OK for a semop to return EINTR, just loop around and try
8444 again. [Dean Gaudet]
8446 *) Fix configuration engine re-entrant hangups, which solve a
8447 handful of problems seen with mod_perl <Perl> configuration sections
8448 [Salvador Ortiz Garcia <sog msg.com.mx>]
8450 *) Mac OS and Mac OS X Server now use the appropriate custom layout
8451 by default when building with APACI; allow for platform-specific
8452 variable defaults in configure. [Wilfredo Sanchez]
8454 *) Do setgid() before initgroups() in http_main; some platforms
8455 zap the grouplist when setgid() is called. This was fixed in
8456 suexec earlier, but the main httpd code missed the change.
8457 [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2579
8459 *) Add recognition of .tgz as a gzipped tarchive.
8460 [Bertrand de Singly <bertrand.de-singly polytechnique.fr>] PR#2364
8462 *) mod_include's fsize/flastmod should allow only relative paths, just
8463 like "include file". [Jaroslav Benkovsky <benkovsk pha.pvt.cz>]
8465 *) OS/2: Add support for building loadable modules using DLLs.
8468 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
8471 *) Fix minor but annoying bug with the test for Configuration.tmpl
8472 being newer than Configuration so that it is less likely to fail
8473 when using APACI and shadow sources. [Wilfredo Sanchez]
8475 *) PORT: Add initial support for Mac OS (versions 10.0 and
8476 greater). Use Mac OS X Server layout for now. Clean up dyld code
8477 in unix/os.c, and don't install the dyld error handlers, which
8478 are no longer needed in Mac OS. [Wilfredo Sanchez]
8480 *) Rename Rhapsody layout to "Mac OS X Server". Change install
8481 locations to appropriate ones for user-built (as opposed to
8482 system) installs. [Wilfredo Sanchez]
8484 *) Modify mod_autoindex's handling of AddDescription so that the
8485 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
8487 *) Add functionality to the install-bindist.sh script created by
8488 binbuild.sh to use tar when copying distribution files to the
8489 serverroot. This allows upgrading an existing installation
8490 without nesting the new distribution in the old.
8492 install-bindist.sh now detects the local perl5 path to install
8493 apxs and dbmmanage with proper path to perl interpreter.
8495 Add an install-binsupport target which copies the source files
8496 for apxs and dbmmanage to bindist to allow these scripts to
8497 be properly installed relative to the destination serverroot.
8498 [Randy Terbush, Covalent Technologies, <randy covalent.net>]
8500 *) Fix intermittent SEGV in ap_proxy_cache_error() in
8501 src/modules/proxy_util.c where a NULL filepointer and
8502 temporary filename were closed and unlinked.
8503 [Graham Leggett <minfrin sharp.fm>,
8504 Tim Costello <tjcostel socs.uts.edu.au>] PR#3178
8506 *) Fix inconsistent error messages reported by mod_proxy.
8507 [Graham Leggett <minfrin sharp.fm>]
8509 *) OS/2: Fix terminating CGIs that aren't compiled by EMX GCC when a
8510 connection is aborted. [Brian Havard]
8512 *) Force the LANG envariable to the known state of "C" so that we
8513 have assurance about how string manipulators (e.g., tr) will
8514 function. [Ken Coar] PR#1630
8516 *) Add a directive to allow customising of the tracking cookie name.
8517 [Ken Coar] PR#2921, 4303
8519 *) Add "force-no-vary" envariable to allow servers to work around
8520 clients that choke on "Vary" fields in the response header.
8521 [Ken Coar, Dmitry Khrustalev <dima zippy.machaon.ru>] PR#4118
8523 *) Fixed a bug in mod_dir that causes a child process will infinitely
8524 recurse when it attemps to handle a request for a directory wnd the
8525 value of the DirectoryIndex directive is a single dot. Also likely
8526 to happen for anyother values of DirectoryIndex that will map back
8527 to the same directory. The handler now only considers regular files
8528 as being index candidates. No PR#s found.
8529 [Raymond S Brand <rsbx rsbx.net>]
8531 *) Ease configuration debugging by making TestCompile fall back to
8532 using "make" if the $MAKE variable is unset [Martin Kraemer]
8534 *) Fixed the ServerSignature directive to work as documented.
8535 [Raymond S Brand <rsbx rsbx.net>] PR#4248
8537 *) Add "opt" (SysV-style) layout to config.layout. [Raymond S Brand
8540 *) Add APACI --without-execstrip option which can be used to disable the
8541 stripping of executables on installation. This is very important for DSO
8542 and debugging situations. [Ralf S. Engelschall]
8544 *) Add support for OS/2 (case insenstive filesystem, .exe suffix, etc)
8545 to APACI files and related scripts.
8546 [Yitzchak Scott-Thoennes <sthoenna efn.org>, Ralf S. Engelschall] PR#4269
8548 *) Add support for standalone mode in TPF
8549 [Joe Moenich <moenich us.ibm.com>]
8551 *) Fix number of bytes copied by read_connection() in src/support/ab.c
8552 [Jim Cox <jc superlink.net>] PR#4271
8554 *) Fix special RewriteCond "-s" pattern matching.
8555 [Bob Finch <bob nas.com>]
8557 *) Fix value quoting in src/Configure script for ap_config_auto.h
8558 [Paul Sutton <paul awe.com>]
8560 *) Make sure RewriteLock can be used only in the global context, (i.e.
8561 outside of any <VirtualHost> sections) because it's a global facility of
8562 the rewrite engine. [Ralf S. Engelschall]
8564 *) Fix the ownership delegation for proxy directory under `make install'.
8565 [Ralf S. Engelschall]
8567 *) APACI would not correctly build suexec. [Maria Verina
8568 <mariav icgeb.trieste.it>] PR#4260
8570 *) mod_mime_magic passed only the first 4k of a file to
8571 uncompress/gzip, but those tools sometimes do not produce
8572 any output unless a sufficient portion of the compressed
8573 file is input. Change to pass the entire file -- but
8574 only read 4k of output.
8575 [Marcin Cieslak <saper system.pl>] PR#4097
8577 *) "IndexOptions None" generated extra spaces at the end of each
8578 line. [<inkling firstnethou.com>] PR#3770
8580 *) The "100 Continue" response wasn't being sent after internal
8581 redirects. [Jose KAHAN <kahan w3.org>] PR#3910, 3806, 3575
8583 *) When padding the name with spaces for display, mod_autoindex would
8584 count &, <, and > in their escaped width, messing up the display.
8585 [Dean Gaudet] PR#4075, 3758
8587 *) PORT: fixed a compilation problem on NEXT.
8588 [Jacques Distler <distler golem.ph.utexas.edu>] PR#4130
8590 *) r->request_time wasn't being set properly in certain error conditions.
8591 [Dean Gaudet] PR#4156
8593 *) PORT: deal with UTS compiler error in http_protocol.c
8594 [Dave Dykstra <dwd bell-labs.com>] PR#4189
8596 *) Add ap_vrprintf() function. [John Tobey <jtobey banta-im.com>] PR#4246
8598 *) Fix the mod_mime hash table to work properly with locales other
8599 than C. [Dean Gaudet] PR#3427
8601 *) Fix a memory leak which is exacerbated by certain configurations.
8602 [Dean Gaudet] PR#4225
8604 *) Prevent clobbering saved IFS values in APACI. [Jim Jagielski]
8606 *) Fix buffer overflows in ap_uuencode and ap_uudecode pointed out
8607 by "Peter 'Luna' Altberg <peter altberg.nu>" and PR#3422
8608 [Peter 'Luna' Altberg <peter altberg.nu>, Ronald Tschalär]
8610 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
8613 *) Correct an apparent typo: on the Windows and MPE platforms, the
8614 htpasswd utility was limiting passwords to only 8 characters.
8617 *) EBCDIC platforms: David submitted patches for two bugs in the
8618 MD5 digest port for EBCDIC machines:
8619 a) the htdigest utility overwrote the old contents of the digest file
8620 b) the Content-MD5 header value (ContentDigest directive) was wrong
8621 when the returned file was not converted from EBCDIC, but was a
8622 binary (e.g., image file) in the first place.
8623 [David McCreedy <mccreedy us.ibm.com>]
8625 *) support/htpasswd now permits the password to be specified on the
8626 command line with the '-b' switch. This is useful when passwords
8627 need to be maintained by scripts -- particularly in the Win32
8628 environment. [Ken Coar]
8630 *) Win32: Win32 multiple services patch. Added capability to install and
8631 run multiple copies of apache as individual services.
8634 apache -n apache1 -i -f c:/httpd.conf
8635 Installs apache as service 'apache1' and associates c:/httpd.conf
8638 Starts apache1 service.
8640 Stops apache1 service
8643 apache -n apache2 -i
8644 Installs apache as service 'apache2'. httpd.conf is located under
8645 the default server root (/apache/conf/httpd.conf).
8647 Starts apache2 service.
8650 apache -n apache3 -i -d c:/program files/apache
8651 Install apache as service 'apache3' and sets server root to
8652 c:/program files/apache.
8655 apache -n apache2 -k restart
8656 Restart apache2 service
8658 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
8660 *) Correct the signed/unsigned character handling for the MD5 routines;
8661 mismatches were causing compilation problems with gcc -pedantic and
8662 in the TPF cross-compilation. [Ken Coar]
8664 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
8665 a roughly 5 fold speed up. [Brian Havard]
8667 *) proxy ftp: instead of using the hardwired string "text/plain" as
8668 a fallback type for files served by the ftp proxy, use the
8669 ap_default_type() function to determine the configured type.
8670 This allows for special configurations like
8671 <Directory proxy:ftp://some.host>
8672 DefaultType gargle/blurb
8674 Additionally, add the Content-Encoding: header to FTP proxy replies
8675 when the encoding is defined (by the AddEncoding directive).
8676 Because it was missing, it was almost impossible to browse compressed
8677 files using the FTP proxy (works now perfectly in Communicator).
8678 The ftp proxy now also returns the Date: and Server: header lines (if not
8679 much else... This code is "somewhat" broken) like normal requests do.
8682 *) Be more smart in APACI's configure script when determining the UID/GID
8683 for User/Group directives and use the determined UID/GID to initialize
8684 the permissions on the proxycachedir.
8685 [Dirk-Willem van Gulik, Ralf S. Engelschall]
8687 *) Changed the forking-prior-to-cleanup in the proxy module to first
8688 check wether it actually needs to collect garbage. This reduces
8689 the number of fork()s from one/request to just the odd one an hour.
8690 [Dirk-Willem van Gulik]
8692 *) Added proxy, auth and header support to src/support/ab.c. Added a
8693 README file to src/support/
8694 [Dirk-Willem van Gulik]
8696 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.
8697 [Ralf S. Engelschall] PR#4050
8699 *) Add support for DSO module compilation on BSD/OS 3.x.
8700 [Randy Terbush, Covalent Technologies]
8702 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
8703 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
8704 option) were substituted with $(TARGET).conf, etc. Same for other strings
8705 with dots where the dot wasn't matched as plain text.
8706 [Ralf S. Engelschall]
8708 *) PORT: Add support for FreeBSD 4.x [Ralf S. Engelschall]
8710 *) Fix verbose output of APACI configure (option -v)
8711 [Martin Kraemer, Ralf S. Engelschall]
8713 Changes with Apache 1.3.6
8715 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
8717 Changes with Apache 1.3.5 [not released]
8719 *) M_INVALID needed a value within the scope of METHODS so that unknown
8720 methods can be access controlled. [Roy Fielding] PR#3821
8722 *) Added PassAllEnv; makes server's entire environment available
8723 to CGIs and SSIs executed within directive's scope. [Ken Coar]
8725 *) ap_uuencode() always added two trailing '='s and encoding of
8726 8 bit characters on a machine with signed char may produced
8727 incorrect results. Additionally ap_uuencode() should now
8728 work correctly on EBCDIC platforms.
8729 [Ronald Tschalär <ronald innovation.ch>] PR#3411
8731 *) WIN32: Binary installer now runs the configuration DLL before
8732 the reboot prompt (which is only given if MSVCRT.DLL system
8733 DLL is new or updated). This should avoid the configuration
8734 directory being empty after installation. [Paul Sutton]
8735 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
8737 *) WIN32: Binary installer now creates Start menu options to start
8738 and stop Apache as a console application and to uninstall
8739 the Apache service on NT. [Paul Sutton] PR#3741
8741 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
8743 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
8744 have been reported with flock() locking (probably related to kernel
8745 version). [Dean Gaudet] PR#2723, 3531
8747 *) Using APACI, the main config file (usually httpd.conf) was
8748 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
8749 <wsanchez apple.com>]
8751 *) PORT: AIX does not require the SHARED_CODE "hack"
8752 [Ryan Bloom <rbb raleigh.ibm.com>]
8754 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
8755 avoidance code added in 1.3.3.
8756 [Dean Gaudet, Jeff Lewis <lewis stanford.edu>] PR#3872
8758 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
8759 for 8-bit safeness. [Dean Gaudet]
8761 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
8762 because SPARCs have a small machine-specific maximum size for the Global
8763 Offset Table which is often exceeded when compiling one of the larger
8764 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977
8766 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
8767 DSO/DLL section because it's a directive from mod_status and isn't
8768 available before the DLL of mod_status is loaded.
8769 [Martin POESCHL <mpoeschl gmx.net>] PR#3936
8771 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
8772 continuation facility in Apache's configuration files which could
8773 lead to a buffer overflow situation.
8774 [Thomas Devanneaux <Thomas.Devanneaux enst.fr>] PR#3617
8776 *) Make documentation and error messages of APACI's --activate-module=FILE
8777 option more clear. [Jan Wolter <janc wwnet.net>] PR#3995
8779 *) Fix the gcc version check (for enabling the `inline' facility) to
8780 really support all future gcc versions >= 2.7 until we know more.
8781 [John Tobey <jtobey banta-im.com>] PR#3983
8783 *) Let APACI's configure script correctly complain for unknown --enable-XXX
8784 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
8786 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
8787 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
8788 possible buffer overflows. [Ralf S. Engelschall]
8790 *) Remove no longer used non-API function ap_single_module_init().
8791 [Ralf S. Engelschall]
8793 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
8796 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
8797 to make platform installations easier. [Wilfredo Sanchez]
8799 *) In configure, do not append the target name to the directory path if
8800 the path already contains "apache". [Ralf S. Engelschall]
8802 *) SIGPIPE is now ignored by the server core. The request write routines
8803 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
8804 correctly check for output errors and mark the connection as aborted.
8805 Replaced many direct (unchecked) calls to ap_b* routines with the
8806 analogous ap_r* calls. [Roy Fielding]
8808 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
8809 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
8810 Furthermore map lookups for non-existent keys are now cached as well.
8811 Additionally "txt" maps are now parsed with simple string functions
8812 instead of using ap_pregcomp(). As a side effect a bug that prevented
8813 the usage of keys containing the "," character was fixed.
8814 The changes drastically improve the performance when large rewrite maps
8816 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
8818 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
8819 other than GET, and const'd the definition of method in request_rec.
8822 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
8824 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
8825 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
8827 *) Add %V to mod_log_config, this logs the hostname according to the
8828 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
8829 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
8831 *) Add support for \n and \t to mod_log_config, can be used to produce
8832 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
8834 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
8836 *) Added informative error messages for failed munmap() and fseek() calls
8837 in http_core.c. [John Bley, Roy Fielding]
8839 *) Added some informative error messages for some failed malloc()
8840 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
8842 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
8843 is removed. This allows <Directory proxy:*> directives to work and
8844 prevents invalid requests from killing the process.
8845 [Brian Havard <brianh kheldar.apana.org.au>]
8847 *) Reorganised FAQ document.
8848 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497
8850 *) src/support/: The ApacheBench benchmark program was overhauled by
8851 David N. Welton: you can now have it generate an HTML TABLE, presumably
8852 for integration into other HTML sources. David updated the ab man page
8853 as well and added some missing descriptions. Thanks!
8854 [David N. Welton <davidw prosa.it>]
8856 *) Win32: The filename validity checker now allows filenames containing
8857 characters in the range 0x80 to 0xff (for example accented characters).
8858 [Paul Sutton] PR#3890
8860 *) Added conditional logging based upon environment variables to
8861 mod_log_config. mod_log_referer and mod_log_agent
8862 are now deprecated. [Ken Coar]
8864 *) Allow apache acting as a proxy server to relay the real
8865 reason of a failure to a client rather than the "internal
8866 server error" it does currently. The general exposure mechanism
8867 can be triggered by any module by setting the "verbose-error-to"
8868 note to "*"; this allows more than just proxy errors to be exposed.
8869 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
8871 *) Moved man pages for ab and apachectrl to section 8.
8872 [Wilfredo Sanchez, Roy Fielding]
8874 *) Added -S option to install.sh so that options can be passed to
8875 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
8877 *) Tweak modules Makefile generated by Configure so that it handles
8878 the test case of no modules being selected. [<chaz reliant.com>]
8880 *) Added a <LimitExcept method ...> sectioning directive that allows
8881 the user to assign authentication control to any HTTP method that
8882 is *not* given in the argument list; i.e., the logical negation
8883 of the <Limit> directive. This is particularly useful for controlling
8884 access on methods unknown to the Apache core, but perhaps known by
8885 some module or CGI script. [Roy Fielding, Tony Finch]
8887 *) Prevent apachectl from complaining if the PIDFILE exists but
8888 does not contain a process id, as might occur if the server is
8889 being rapidly restarted. [Wilfredo Sanchez]
8891 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
8893 *) Entity tag comparisons for If-Match and If-None-Match were not being
8894 performed correctly -- weak tags might cause false positives. Also,
8895 strong comparison wasn't properly enforced in all cases.
8896 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
8898 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
8901 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
8902 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
8904 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
8905 to util.c for parsing an HTTP header field value to extract the next
8906 list item, taking into account the possible presence of nested comments,
8907 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
8908 insignificant whitespace and lowercases non-quoted tokens.
8909 [Roy Fielding] PR#2065
8911 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
8912 code different from 500. This allows the proxy to, e.g., return
8913 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
8915 *) Fix ordering of language variants for the case where the traditional
8916 negotiation algorithm is being used with multiple language variants
8917 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
8919 *) Do not round the TCN quality calculation to 5 decimal places,
8920 unlike RFC 2296, because the calculation might need 12 decimal places
8921 to get the right result. [Roy Fielding]
8923 *) Remove unused code to disable transparent negotiation when
8924 negotiating on encoding only, as we now handle encoding too
8925 (though this is nonstandard for TCN), remove charset=ISO-8859-1
8926 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
8927 some debugging statements within mod_negotiation. [Koen Holtman]
8929 *) Fixed a rare memory corruption possibility in mod_dir if the index
8930 file is negotiable and no acceptable variant can be found.
8931 [Dean Gaudet, Roy Fielding, Martin Kraemer]
8933 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
8934 searching the Win32 registry for script interpreters.
8937 *) Win32: The compiled-in default filename for the error log is now
8938 error.log, which matches the default in the distributed httpd.conf.
8941 *) Win32: Any error messages from -i or -u command line options are now
8942 displayed on the console output rather than sent to the error log.
8943 Also the "Running Apache..." message is not output unless Apache is
8944 going to serve requests. [Paul Sutton]
8946 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
8947 and use a private significator ('$apr1$') to mark passwords as
8948 being smashed with our own algorithm. Also abstract the password
8949 checking into a new ap_validate_password() routine. [Ken Coar]
8951 *) Win32: The filename validity checker now allows "COM" but refuses
8952 access to "COM1" through "COM4". This allows filenames such
8953 as "com.name" to be served. [Paul Sutton] PR#3769.
8955 *) BS2000: Adapt to the new ufork() system call interface which will
8956 make subtasking easier on the OSD/POSIX mainframe environment.
8959 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
8960 ap_compat.h. [David White <david persimmon.com>] PR#3725
8962 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
8963 use `.db' instead of `.pag' not only for FreeBSD, but also when
8964 the NDBM library looks like Berkeley-DB based.
8965 [Ralf S. Engelschall] PR#3773
8967 *) Add ability to handle DES or MD5 authentication passwords.
8968 [Ryan Bloom <rbb Raleigh.IBM.Com>]
8970 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
8972 *) SECURITY: Avoid some buffer overflow problems when escaping
8973 quoted strings. (This overflow was on the heap and we believe
8974 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
8976 *) Let src/Configure be aware of CFLAGS options starting with plus
8977 signs as it's the case for the HP/UX compiler.
8978 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
8980 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
8981 and check to see if the tar we wind up with supports '-h'.
8982 [Jim Jagielski] PR#3671
8984 *) A consistent and conservative style for all shell scripts has been
8985 implemented. Basically, all shell string tests use the traditional
8986 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
8987 to protect against bare null variable strings (ie: wrapping both
8988 sides with double quotes and prepending 'x'). 'x' was chosen
8989 because it's more universal and hopefully easier for old shell
8990 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
8993 *) The status module now prints out both the main server generation as
8994 well as the generation of each process. Also, the vhost info is
8995 printed with '?notable'. [Jim Jagielski]
8997 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
8998 and this makes its functions available to things in src/support.
9001 Changes with Apache 1.3.4
9003 *) Renamed macros status_drops_connection to ap_status_drops_connection
9004 and vestigial scan_script_header to ap_scan_script_header_err,
9005 mostly for aesthetic reasons. [Roy Fielding]
9007 *) The query switch "httpd -S" didn't exit after showing the
9008 vhost settings. That was inconsistent with the other query functions.
9011 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
9012 filename to the end of the STANDARD_MODULE_STUFF. Its
9013 presence at the beginning prevented reporting of the filename
9014 for modules compiled before 1 January 1999. [Ken Coar]
9016 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
9017 to detect and prevent access to special DOS device file names.
9018 [Paul Sutton, Ken Parzygnat]
9020 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
9021 and Makefile_win32_debug.txt (debug build) that work on Win95.
9022 Run each of the following from the src directory:
9023 nmake /f Makefile_win32.txt # compiles normal build
9024 nmake /f Makefile_win32.txt install # compiles and installs
9025 nmake /f Makefile_win32.txt clean # removes compiled junk
9026 nmake /f Makefile_win32_debug.txt # compiles debug build
9027 nmake /f Makefile_win32_debug.txt install
9028 nmake /f Makefile_win32_debug.txt clean
9031 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
9032 to build binary distributions. [Lars Eilebrecht]
9034 *) IndexOptions SuppressColumnSorting only turned off making
9035 the column headers anchors; you could still change the display
9036 order by manually adding a '?N=A' or similar query string to the
9037 URL. Now SuppressColumnSorting locks in the sort order so
9038 it can't be overridden this way. [Ken Coar]
9040 *) Added IndexOrderDefault directive to supply a default sort order
9041 for FancyIndexed directory listings. [Ken Coar] PR#1699
9043 *) Change the ap_assert macro to a variant that works on all platforms.
9044 [Richard Prinz <richard.prinz cso.net>] PR#2575
9046 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
9047 search for an underscore on dlsym() (as it's already the case
9048 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
9050 *) Small fix for mod_env.html: The module was documented as to be _not_
9051 compiled into Apache per default, although it _IS_ compiled into
9052 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
9054 *) Instead of fixing a bug in the generation procedure for config.status (a
9055 backslash was missing) we remove the bug together with it's complete
9056 context because the special cases of the past can now no longer occur
9057 because of the recent magic for the --with-layout default.
9058 [Ralf S. Engelschall] PR#3590
9060 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
9061 making sure the src/support/ tools are _forced_ to be build last (they
9062 depend on other libraries).
9063 [Markus Theissinger <markus.theissinger gmx.de>]
9065 *) Fix installation procedure: Now that os-inline.c is actually used (a
9066 recently fixed bug prevented this) we need to also install os-include.c
9067 in addition to os.h into the PREFIX/include/ location or building of
9068 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
9070 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
9071 allow us to distinguish between a garbled DSO (or even a file which isn't
9072 an Apache module DSO at all) and a DSO which doesn't match the current
9073 Apache API. [Ralf S. Engelschall] PR#3152
9075 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
9076 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
9077 match case insensitive (this especially avoids nasty patterns like
9078 `[tT][eE][sS][tT]'). Second two additional internal map functions
9079 `escape' and `unescape' were added which can be used to escape/unescape
9080 to/from hex-encodings in URLs parts (this is especially useful in
9081 combination with map lookups).
9082 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
9084 *) Renamed the macro escape_uri() to ap_escape_uri() which was
9085 forgotten (because it was a macro) in the symbol renaming process.
9086 [Ralf S. Engelschall]
9088 *) Fix some inconsistencies related to the scopes of directives. The only
9089 user visible change is that the directives `UseCanonicalName' and
9090 `ContentDigest' now use the (more correct) `Options' scope instead of
9091 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
9093 *) Using DSO, the Server token was being mangled. Specifically, the
9094 module's token was being added first before the Apache token. This
9095 has been fixed. [Jim Jagielski]
9097 *) Major overhaul of mod_negotiation.c, part 2.
9098 - properly handle "identity" within Accept-Encoding.
9099 - allow encoded variants in RVSA negotiation and let them appear in
9100 the Alternates field using the non-standard "encoding" tag-list.
9101 - fixed both negotiation algorithms so that an explicitly accepted
9102 encoding is preferred over no encoding if "identity" is not
9103 included within Accept-Encoding.
9104 - added ap_array_pstrcat() to alloc.c for efficient concatenation
9105 of large substring sequences.
9106 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
9109 *) Major overhaul of mod_negotiation.c, part 1.
9110 - cleanups to mod_negotiation comments and code structure
9111 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
9112 support for everything in the upcoming HTTP/1.1
9113 revision (draft-ietf-http-v11-spec-rev-06.txt).
9114 - language tag matching also handles tags with more than 2
9116 - empty Accept, Accept-Language, Accept-Charset headers are
9117 processed correctly; previously an empty header would make all
9118 values acceptable instead of unacceptable.
9119 - allowed for q values in Accept-Encoding
9120 - added support for transparent content negotiation (rfc2295 and
9121 rfc2296) (though we do not implement all features in these drafts,
9122 e.g. no feature negotiation). Removed old experimental version.
9123 - implemented 'structured entity tags' for better cache correctness
9124 (structured entity tags ensure that caches which can deal with Vary
9125 will (eventually) be updated if the set of variants on the server
9127 - this involved adding a vlist_validator element to request_rec
9128 - this involved adding the ap_make_etag() function to the global API
9129 - modified guessing of charsets used by Apache negotiation algorithm
9130 to guess 'no charset' if the variant is not a text/* type
9131 - added code to sort multiviews variants into a canonical order so that
9132 negotiation results are consistent across backup/restores and mirrors
9133 - removed possibility of a type map file resolving to another type map
9134 file as its best variant
9135 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
9137 *) RFC2396 allows the syntax http://host:/path (with no port number)
9138 but the proxy disallowed it (ap_proxy_canon_netloc()).
9139 [David Kristol <dmk bell-labs.com>] PR#3530
9141 *) When modules update/modify the file name in the configfile_t structure,
9142 syntax errors will report the updated name, not the original one.
9143 [Fabien Coelho <coelho cri.ensmp.fr>] PR#3573
9145 *) Correct some filename case assumptions from WIN32 to
9146 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
9148 *) For %v log ServerName regardless of the UseCanonicalName
9149 setting (similarly for %p). [Dean Gaudet]
9151 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
9152 rather late (too late for some invocations of TestCompile).
9153 This improves the make environment available to TestCompile and
9154 the *.module scripts. [Martin Kraemer]
9156 *) The hashbang emulation code in ap_execve.c would interpret
9157 #!/hashbang/scripts correctly, but failed to fall back to a
9158 standard shell for scripts which did NOT start with #!
9159 Now SHELL_PATH is started in these cases. [Martin Kraemer]
9161 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
9164 *) Update APXS manual page: some -q option arguments were missing
9165 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
9167 *) Cleanup the command line options: `-?' was documented to show
9168 the usage list but does it with an error because `?' is not a valid
9169 command. OTOH a lot of users expect `-h' to print such a usage list and
9170 instead are annoyed for ages by our huge unreadable list of directives.
9171 So we now changed the command line options this way:
9173 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
9174 very similar to the popular linker option.
9176 Intent: while -l gives the small list of modules, -L now gives the
9177 large list of directives implemented by these modules. This is also
9178 consistent with -v (short version info) and -V (large version info).
9180 Intent: it's now the expected option ;-)
9181 The manual page was adjusted accordingly.
9182 [Ralf S. Engelschall] PR#2714
9184 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
9185 wasn't defined. [Rick Franchuk <rickf transpect.net>]
9187 *) Removed recently introduced bugs and disfigurements in APACI:
9188 o fixed argument line processing: using $args was broken: It was not
9189 initialized and using args="$args $apc_option" and even args="$args
9190 \"$apc_option\"" fails in the second processing round for any arguments
9191 containing whitespaces. The only correct way is to use the construct
9192 "$@" (but not possible here) or iterate _both_ times over the implicit
9193 argument line (no argument to for-loop) which is what we now use.
9194 o make --with-layout=Apache the default without creating
9195 redundancy (copying the --with-layout block in the argument parsing
9196 loop). We achieve this by using the "$@" construct together with the
9197 `set' command to prepend --with-layout=Apache to the command line in
9198 case --with-layout is not used.
9199 o fixed auto-suffix handling now that config.layout exists.
9200 Paths which are auto-suffixed are marked with a trailing plus sign in
9201 config.layout and every path now can be marked this way (not only the
9202 four paths for which we do it currently). Additionally the suffix is
9203 no longer a static one. Instead it's now `/<target>' where <target> is
9204 the argument of the --target option or per default `httpd'.
9205 o allow also tabs (and only spaces) where we match whitespaces
9206 o various fixes and cleanups related to used shell coding style
9207 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
9208 o trimmed output of --help to fit into 80 columns
9209 [Ralf S. Engelschall]
9211 *) Added two new core API functions, ap_single_module_configure() and
9212 ap_single_module_init(), which are now used by mod_so to configure a module
9213 after loading. [Ralf S. Engelschall]
9215 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
9216 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
9217 of ap_config.h to allow serialized accept for multiport listens.
9218 [Roy Fielding, Curt Sampson] PR#3120
9220 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
9221 of ap_config.h that would skip several defines if DEFAULT_GROUP
9222 was overridden. [Roy Fielding]
9224 *) PORT: The I86 version of DGUX has support for strncasecmp and
9225 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
9227 *) Fix ordering of definitions in ap_config.h so that ap_inline is
9228 defined before it might be used. [Victor Khimenko]
9230 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
9231 [Tom Serkowski <tks bsdi.com>] PR#3453
9233 *) Make generation of src/Configuration.apaci more robust: It failed to
9234 differenciate between modules when one module name was a postfix of
9235 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
9236 just XXX (think about totally non-standard names like "apache_ssl", too).
9237 [Ralf S. Engelschall] PR#3380
9239 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
9240 since 1.3b7) and make whitespace handling more robust (it failed horrible
9241 when whitespaces were present in the arguments of -D options).
9242 [Ralf S. Engelschall] PR#3240
9244 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
9245 creates an external package shadow tree in DIR before the local build
9246 shadow tree is generated under DIR. This way one can have the extracted
9247 Apache distribution tree read-only on NFS or CDROM and still build Apache
9248 from these sources. An automatically triggered VPATH-like mechanism is
9249 provided through the TOP variable, too.
9250 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez apple.com>]
9252 *) Fix negotiation so that a Vary response header is correctly
9253 generated when, for a particular dimension, variants only vary
9254 in having or not having a value for that dimension. [Paul Sutton]
9256 *) Fix negotiation so that we prefer an encoded variant over an
9257 unencoded variant if the user-agent explicitly says it can
9258 accept that encoding. Previously we always preferred the unencoded
9260 [Paul Ausbeck <paula alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
9262 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
9263 and the usage page was inconsistent with the functionality and manpage.
9264 [Ralf S. Engelschall]
9266 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
9267 They can occur multiple times and their arguments (`xxx') are passed AS
9268 IS to the compiler/linker command. [Ralf S. Engelschall]
9270 *) Fixed possible (but harmless in practice) bug in the DBM lookup
9271 procedure of mod_rewrite: very long keys were truncated.
9272 [Ralf S. Engelschall]
9274 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
9275 identifier, currently "Apache" and "GNU" are pre-defined in the file
9276 config.layout. Custom layouts are possible by using FILE:ID as the
9277 argument where the layout ID is taken from FILE.
9279 The config.layout file consists of <Layout ID>..</Layout> sections
9280 where inside those sections "path_variable: path_value" pairs can be
9281 specified. These lines are converted to path_variable='path_value'.
9283 *) Add a DefaultLanguage directive so that files missing a language
9284 extension (e.g., .fr, .de) can be labelled as being some other
9285 default language. DefaultLanguage can appear in <Directory> and
9286 <Files> containers as well as .htaccess files. [Paul Sutton]
9289 *) Fix TARGET configuration when configuring and installing using
9290 APACI configure. TARGET now defines the basename of the configuration
9291 file, startup script, manual page, etc. log_error_core() now reports
9292 the server binary name given by argv[0]. TARGET can now also be defined
9293 with --target=TARGET parameter passed to APACI configure.
9294 [Ralf Engelschall, Randy Terbush]
9296 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
9297 rather than OPT_INCLUDES [Rainer Schoepf <schoepf uni-mainz.de>]
9299 *) ap_md5_binary() was using sprintf() rather than a table lookup
9300 to convert binary bytes to hex digits.

9309 when either a handler or a MIME content type is triggered by the request.
9310 [Andrew Pimlott <pimlott math.harvard.edu>] PR#3340
9312 *) Document the `add' command of `dbmmanage' in `dbmmanage.1' manpage.

9316 notice to the error log. It is not possible to send a 401 response
9317 and a redirect at the same time. [Lars Eilebrecht]
9319 *) Fallback to native compilers for IRIX-32 platform. It seems that
9320 a gcc 2.8.1 compiled apache is logging client addresses with all
9321 bits set (255.255.255.255). This is the second such problem caused
9322 by gcc 2.8.1 compiler. The first being broken semaphore locking.
9325 *) Updated mime.types to reflect current Internet media types
9326 and include a URL to the registry.
9327 [Manoj Kasichainula, Roy Fielding] PR#2380, 2286, 2246
9329 *) SECURITY: Do a more complete check in mod_include to avoid
9330 an infinite loop of recursive SSI includes. [Marc Slemko] PR#3323

9333 used to set the document root directory (DOC_ROOT) and the suexec
9334 logfile (LOG_EXEC), respectively. Additionally the --layout option
9335 was changed to show more information about the suEXEC setup.

9400 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
9401 in the Configuration[.apaci] file. Two special and important variants are
9402 supported for the option argument: first BEGIN:foo which permutes module
9403 mod_foo with the begin of the module list, i.e. it `moves' the module to
9404 the begin of the list (gives it lowest priority). And second foo:END
9405 which permutes mod_foo with the end of the module list, i.e. it `moves'
9406 the module to the end of the list (gives it highest priority).

9450 you to override a specific handler. [Marc Slemko]
9452 *) Further simplify checking for absolute paths by replacing an
9453 hard-coded syntax check with a call to a routine we already created to
9454 do this. [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2976, 3074
9456 *) Log an error if we encounter a malformed "require" directive
9457 in mod_auth if we know that we know that no other module can
9458 deal with it. [Marc Slemko]
9460 *) Remove ap_private_extern method of hiding conflicting symbols
9461 on the NEXT platform because it is not correct for all versions,
9462 and the versions for which it is correct are unknown.
9463 [Wilfredo Sanchez <wsanchez apple.com>]
9465 *) Fix inheritance of IndexOptions NameWidth and remove unintended
9466 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
9468 *) Fix per-directory config merging for cases in which a 500 error
9469 is encountered in an .htaccess file somewhere down the tree.
9472 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
9474 *) Fixed a segmentation violation in mod_proxy when a response is
9475 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
9477 Changes with Apache 1.3.3
9479 *) Added a complete implementation of the Expect header field as
9480 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
9481 response when we already know the final status, which is mighty
9482 useful for PUT responses that result in 302 or 401. [Roy Fielding]
9484 *) Remove extra trailing whitespace from the getline results as part
9485 of the protocol processing, which is extra nice because it works
9486 between continuation lines, is almost no cost in the normal case
9487 of no extra whitespace, and saves memory. [Roy Fielding]
9489 *) Added new HTTP status codes and default response bodies from the
9490 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
9491 HTTP Extension Framework (510) specifications. Did not add the
9492 WebDAV 424 and 425 codes because they are bogus. We don't use any
9493 of these codes yet, but they are now available to 3rd-party modules.
9496 *) Fix a possible race condition between timed-out requests and the
9497 ap_bhalfduplex select that might result in an infinite loop on
9498 platforms that do not validate the descriptor. [Roy Fielding]
9500 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
9501 running Apache server [Paul Sutton]
9503 *) Fix mod_autoindex bug where directories got a size of "0k" instead
9504 of "-". [Martin Plechsmid <plechsmi karlin.mff.cuni.cz>, Marc Slemko]
9507 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker jetair.be>]
9509 *) Add the server signature text (from the core ServerSignature directive)
9510 to the list of envariables available to scripts, SSI, and the like.
9513 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
9514 [M. Laak <maert proinv.ee>] PR#3108
9516 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
9517 calculation in mod_status for all systems which don't have POSIX
9518 sysconf() (like UTS 2.1) and not only for the NEXT platform.
9519 [Dave Dykstra <dwd bell-labs.com>] PR#3055
9521 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
9522 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
9523 instead of ap_getword(..., ' ') (which parses only according to spaces
9524 but not tabs). [James Morris <jmorris intercode.com.au>,

9544 it is now taken care of properly by the header file tests.

9551 working directory to fill in some blanks. [Ken Parzygnat
9552 <kparz raleigh.ibm.com>] PR#3001
9554 *) Correct invalid assumption by ap_sub_req_lookup_file() that all
9555 absolute paths begin with "/" -- because they don't on Win32.
9556 [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2976, 3074
9558 *) Add [REDIRECT_]VARIANTS environment variable to mod_speling
9559 so that ErrorDocument 300 processors can reformat the list
9560 if desired. [Ken Coar] PR#2859
9562 *) Add +/- incremental prefixes to IndexOptions keywords, and
9563 enable merging of multiple IndexOptions directives. [Ken Coar]
9565 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
9566 <steve.cameron compaq.com>]
9568 *) Reconstructed the loop through multiple htaccess file names so
9569 that missing files are not confused with unreadable files.
9572 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
9573 errno on an error, which leads to one error being mistaken for
9574 another when reading non-existent .htaccess files.
9577 *) OS/2: The new header tests get things right, need to update
9578 ap_config.h. [Brian Havard]
9580 *) The Perl %ENV hash will now be setup by default when using the
9581 mod_include `perl' command [Doug MacEachern]
9583 *) PORT: Add Pyramid DC/OSx support to configuration mechanism.

9590 [Elf Sternberg <elf halcyon.com>]
9592 *) Avoid possible line overflow in Configure: Use an awkfile to
9593 handle the creation of modules.c [Jim Jagielski]
9595 Changes with Apache 1.3.2
9597 *) Fix bug in ap_remove_module(), which caused problems for dso's
9598 who were the top_module. [Doug MacEachern]
9600 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
9601 mod_auth_db to both be friendly to users who wants to use this version
9602 and to avoid problems under platforms where only version 2.x is present.
9603 [Dan Jacobowitz <drow false.org>, Ralf S. Engelschall]
9605 *) When using ap_log_rerror(), make the error message available to the
9606 *ERROR_NOTES envariables by default. [Ken Coar]
9608 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
9609 You now must define a BS2000Account name for the server User.
9610 This has fewer security implications than the old approach.
9613 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
9614 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
9615 platform to make the braindead HPUX linker happy. Notice, for the module
9616 DSOs we don't have to use this, because these are loaded manually (and
9617 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
9619 *) Remove 64 thread limit on Win32.
9620 [Bill Stoddard <stoddard raleigh.ibm.com>]
9622 *) Remove redundant substitutions in top-level Makefile.tmpl.
9623 [Ralf S. Engelschall]
9625 *) Fix APACI's `Group' configuration adjustment - especially for Linux
9626 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
9628 *) Make PrintPath work generically instead of having one version
9629 strictly for OS/2. [Jim Jagielski, Brian Havard]
9631 *) Fix the recently introduced C header file checking: We now use the C
9632 pre-processor pass only (and no longer the complete compiler pass) to
9633 determine whether a C header file exists or not. Because only this way
9634 we're safe against inter-header dependencies (which caused horrible
9635 portability problems). The only drawback is that we now have a CPP
9636 configuration variable which has to be determined first (we do a similar
9637 approach as GNU Autoconf does here). When all fails the user still has
9638 the possibility to override it manually via APACI or src/Configuration.
9639 As a fallback for the header check itself we can directly check the
9640 existance of the file under /usr/include, too.
9641 [Ralf S. Engelschall] PR#2777
9643 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
9644 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
9645 ap_private_extern defined to hide symbols that conflict with loaded
9646 dynamic libraries on the NEXT and RHAPSODY platforms.
9647 [Wilfredo Sanchez <wsanchez apple.com>]
9649 *) Delete PID file on clean shutdowns.

9661 *) Fix possible buffer overflow situation in suexec.c.
9662 [Jeff Stewart <jws purdue.edu>] PR#2790
9664 *) Add some more LIBS for the SCO5 platform which are needed for the already
9665 used -lprot. It's actually a bug in SCO5, of course.
9666 [Ronald Record <rr sco.com>] PR#2533
9668 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
9669 trailing slash problem. [Jon Drukman <jsd gamespot.com>] PR#2933
9671 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
9672 platform, because it's only supported under version 4.0 and higher. But
9673 because our GuessOS is still unaware of Digital UNIX versions and the
9674 -msym is just to optimize the DSO statup time a little bit it's safe and
9675 best when we leave it out now. [Ralf S. Engelschall] PR#2969
9677 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
9678 functions: First all three functions no longer fail on strings containing
9679 "%" chars and second ap_log_printf() no longer does a double-formatting
9680 (instead it directly passes through the message to be formatted to the
9681 real internal formatting function). [Ralf S. Engelschall] PR#2941
9683 *) Allow "Include" directives anywhere in the server config
9684 files (but not .htaccess files). [Ken Coar] PR#2727
9686 *) The proxy was refusing to serve CONNECT requests except to
9687 port 443 (https://) and 563 (snews://). The new AllowCONNECT
9688 directive allows the configuration of the ports to which a
9689 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
9691 *) mod_expires will now act on content that is not sent from a file
9692 on disk. Previously it would never add an Expires: header to
9693 any response that did not come from a file on disk; the only
9694 case where it still doesn't (and can't) add one for that type of
9695 content is if you are using a modification date based setting.
9696 [Marc Slemko, Paul Phillips <paulp go2net.com>]
9698 *) Problems encountered during .htaccess parsing or CGI execution
9699 that lead to a "500 Server Error" condition now provide explanatory
9700 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
9703 *) Add NameWidth keyword to IndexOptions directive so that the
9704 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
9707 *) Recognize lowercase _and_ uppercase `uname' results under
9708 SCO OpenServer. [David Coelho <drc ppt.com>]
9710 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
9711 a common problem of (mis-administrated?) IIS servers, make the apache
9712 proxy immune to these errors (and ignore the duplicates, but log
9713 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
9715 *) The <IfModule and <IfDefine block starting directives now only
9716 allow exactly one argument. Previously, the optional negation
9717 character '!' could be separated by whitespace without a syntax
9718 error being reported, albeit defeating the IfModule functionality
9719 (enclosed directives would ALWAYS be executed). By using the
9720 stricter syntax, these hard-to-track errors can be avoided.
9723 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
9724 cause the standalone FancyIndexing directive to logically OR
9725 into any existing IndexOptions settings rather than wiping
9726 them out. [Ken Coar]
9728 *) Changes in ftp proxy: make URL parsing simpler by using the
9730 + Add display of the "current directory" in cases where it's
9731 different from the supplied path (e.g., ftp://user@host/ lives
9732 in /home/user, not in /, therefore clicking on "../" in the
9733 starting directory might send us to /home/).
9734 + When ftp login fails, (esp. when a user name was part of the
9735 URL already), we now return [401 Unauthorized ] to allow the
9736 browser to pop up an authorization dialog. This makes passwords
9737 slightly less visible (they don't appear in the regular log files)
9738 and implements a functionality that other www proxy servers
9742 *) Triggered by the recent "Via:" header changes, the proxy module would
9743 dump core for replies with invalid headers (e.g., duplicate
9744 "HTTP/1.0 200 OK" lines). These errors are now logged and the
9745 core dump is avoided. Also, broken replies are not cached.
9746 [Martin Kraemer] PR#2914
9748 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
9749 plop gmon.out profile data for each child [Doug MacEachern]
9751 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
9752 config.status script to be immune against arguments with whitespaces.
9753 [Yves Arrouye <yves apple.com>] PR#2866
9755 *) Replace the inlined information grabbing stuff for the configuration
9756 adjustment feature (no --without-confadjust) with calls to a new helper
9757 script `buildinfo.sh' which is both more flexible and already proofed to
9758 be more robust against platform differences. This mainly fixes the
9759 recently occured ``sed: command garbled: ...'' problems.
9760 [Ralf S. Engelschall] PR#2776, PR#2848
9762 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
9763 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
9764 without complains after we recently added the POST feature.
9765 [Ralf S. Engelschall]
9767 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
9768 modules as API functions and we forgot them at the big symbol renaming.
9769 [Ralf S. Engelschall]
9771 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
9772 [Youichirou Koga <y-koga jp.FreeBSD.ORG>] PR#2895
9774 *) Dynamically size the filename column of mod_autoindex output.
9777 *) Add the ability to do POST requests to the ab benchmarking tool.
9778 [Kurt Sussman <kls best.com>] PR#2871
9780 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
9781 5 to 10 because there are some users out there who always have 5 to 8
9782 variables in one RewriteRule and had to patch mod_rewrite.h for every
9783 release. So 15 should be now more than enough, even for them. (I never
9784 needed more than 4 in my RewriteRules ;-)
9785 [Ralf S. Engelschall]
9787 *) Make the proxy generate and understand Via: headers
9790 *) Change the proxy to use tables instead of array_headers for
9791 the header lines. [Martin Kraemer]
9793 *) Make sure the config.status file is not overridden when just
9794 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
9796 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
9797 provide a way to trace API changes that add functionality but do
9798 not create a compatibility issue for precompiled modules, etc.
9799 See include/ap_mmn.h for more details. [Randy Terbush]
9801 *) Fix suexec installation under `make install root=xxx' situation.
9802 [Ralf S. Engelschall]
9804 *) Extend the output of the -V switch to include the paths of all
9805 compiled-in configuration files, if they were overridden at
9806 compile time, for least astonishment of the user.
9809 *) When READing a request in ExtendedStatus mode, the "old"
9810 vhost, request and client information is not displayed.
9813 *) STATUS is no longer available. Full status information now
9814 run-time configurable using the ExtendedStatus directive.
9817 *) SECURITY: CVE-1999-1199 (cve.mitre.org)
9818 Eliminate O(n^2) space DoS attacks (and other O(n^2)
9819 cpu time attacks) in header parsing. Add ap_overlap_tables(),
9820 a function which can be used to perform bulk update operations
9821 on tables in a more efficient manner. [Dean Gaudet]
9823 *) SECURITY: Added compile-time and configurable limits for
9824 various aspects of reading a client request to avoid some simple
9825 denial of service attacks, including limits on maximum request-line
9826 size (LimitRequestLine), number of header fields (LimitRequestFields),
9827 and size of any one header field (LimitRequestFieldsize). Also added
9828 a configurable directive LimitRequestBody for limiting the size of the
9829 request message body. [Roy Fielding]
9831 *) Make status module aware of DNS and logging states, even if
9832 STATUS not defined. [Jim Jagielski]
9834 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
9836 *) Enhance mod_speling so that CheckSpelling can be used in
9837 <Directory> containers and .htaccess files. [Ken Coar]
9839 *) API: new ap_custom_response() function for hooking into the
9840 ErrorDocument mechanism at runtime [Doug MacEachern]
9842 *) API: new ap_uuencode() function [Doug MacEachern]
9844 *) API: scan_script_header_err_core() now "public" and renamed
9845 ap_scan_script_header_err_core() [Doug MacEachern]
9847 *) The 'status' module will now show the process pid's and their
9848 state even without full STATUS accounting. [Jim Jagielski]
9850 *) Restore the client IP address to the error log messages, this
9851 was lost during the transition from 1.2 to 1.3. Add a new
9852 function ap_log_rerror() which takes a request_rec * and
9853 formats it appropriately. [Dean Gaudet] PR#2661
9855 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
9856 whitespace in input lines -- including within quoted strings.
9858 but leading and trailing whitespace should continue to be
9859 stripped [Martin Kraemer]
9861 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
9862 the ugly use of an env. variable and use command-line args for
9863 alternate $PATH. Make more like advanced 'type's as well.
9866 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
9867 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
9868 <alain.st-denis ec.gc.ca>] PR#2736
9870 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
9872 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
9873 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
9874 directory was renamed to src/os/os2/ for consistency.
9875 [Brian Havard, Ralf S. Engelschall]
9877 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
9878 files (here modules) against other DSO files (here shared libraries).
9879 This is done by determining a subset of LIBS which can be safely used for
9880 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
9881 disabled for all platforms to avoid problems with this (experimental)
9882 rule. But we provide it now for those people how ran into problems and
9883 want to came out by forcing linking against DSOs.

9902 *) One more portability fix for APACI shadow tree support: Swap order of awk
9903 and sed in top-level configure script to avoid sed fails on some

10192 *) Improve performance of directory listings (mod_autoindex) by comparing
10193 integer keys (last-modified and size) as integers rather than converting
10194 them to strings first. Also use a set of explicit byte tests rather
10195 than strcmp() to check for parent directory-ness of an entry. Oh, and
10196 make sure the parent directory (if displayed) is *always* listed first
10197 regardless of the sort key. Overall performance winnage should be good
10198 in CPU time, instruction cache, and memory usage, particularly for large
10199 directories. [Ken Coar]
10201 *) Add a tiny but useful goody to APACI's configure script: The generation

10204 just re-running this script or for remembering the configuration between

10208 *) Add httpd -t (test) option for running configuration syntax tests only.
10209 If something is broken it complains and exits with a return code
10210 non-equal to 0. This can be used manually by the user to check the Apache
10211 configuration after editing and is also automatically used by apachectl
10212 on (graceful) restart command to make sure Apache doesn't die on restarts
10213 because of a configuration which is now broken since the last (re)start.
10214 This way `apachectl restart' can be used inside cronjobs without having
10215 to expect Apache to be falling down. Additionally the httpd -t can be run
10216 via `apachectl configtest'.

10368 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
10369 was updated to use the normal apache error processing, thereby allowing
10370 proxy errors to be treated by ErrorDocument's as well. For this
10371 purpose, a new module-to-core communication variable "error-notes"
10372 was introduced; the proxy (and possibly other modules) communicates
10373 its error text using this variable. Its content is copied to a new
10374 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
10375 The old proxy special error routine ap_proxy_log_uerror()

10434 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
10437 *) Improve RFC1413 support. [Bob Beck <beck bofh.ucs.ualberta.ca>]
10439 *) Fix support script `dbmmanage': It was unable to handle some sort
10440 of passwords, especially passwords with "0" chars.
10441 [Ralf S. Engelschall] PR#2242
10443 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
10444 [Ben Laurie] PR#2238
10446 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
10447 library), so CGI handling has been changed to use Win32 native handles
10448 instead of C file descriptors.
10449 [Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
10451 *) The proxy cache would store an incorrect content-length in the cached
10452 file copy after a cache update. That resulted in repeated fetching
10453 of the original copy instead of using the cached copy.
10454 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
10456 *) The Makefiles assumed that DSO files are build via $(LD). This
10457 is broken for two reasons: First we never defined at least LD=ld
10458 somewhere to make sure this works (it was silently assumed that most Make
10459 provide a built-in LD definition - ARGL!) and second using the generic LD
10460 variable is not the truth. Instead a special variable named LD_SHLIB is
10461 reasonable because although "ld" is usually the default, the command for
10462 building DSO files can be "libtool" or even "cc" on some systems.
10463 [Ralf S. Engelschall]
10465 *) Replace the AddVersionPlatform directive with ServerTokens which
10466 provides for more control over the format of the Server:
10467 header line. SERVER_SUBVERSION is no longer supported;
10468 all module should use the ap_add_version_component()
10469 API function instead. [Jim Jagielski]
10471 *) Support for the NCR MP/RAS 3.0
10472 [John Withers <withers semi.kcsc.mwr.irs.gov>]
10474 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
10475 not retrieved in src/Configure and thus was not useable.
10476 [Ralf S. Engelschall]
10478 *) Various Makefile consistency cleanups:
10479 - make OSDIR also automatically be relative to src/ like INCDIR
10480 - SUBDIRS is now generated in src/Makefile only and not in
10481 Makefile.config because it is a local define for this location.
10482 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
10483 any Makefile but make sure that at least the "-K inline" is kept in
10485 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
10486 - updated the dependencies theirself
10487 - removed not existing SHLIB variable from "clean" targets
10488 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
10489 already exists and OBJS_PIC are also just plain objects and have not
10490 directly to do with "shared" things. The only difference is that they
10491 contain PIC. So OBJS_PIC is the more canonical name.
10492 - Updated the Makefile-dependency lines for OBJS_PIC
10493 - Removed the Makefile-dependency line in Configure to avoid double
10495 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
10496 of xxx.lo as GNU libtool does with its PIC objects
10497 - reduce local complexity in modules Makefile.tmpl by moving the last
10498 existing target "depend" to the generation section in Configure, too.
10499 - removed the historical $(SPACER) which was used in the past together
10500 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
10501 is no longer needed.
10502 - force the build and run of the gen_xxx programs under main/ as the
10503 first step before building the objects because it looks cleaner
10504 [Ralf S. Engelschall]
10506 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
10509 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
10512 *) WIN32: Don't force ISAPI headers to finish with \n.
10513 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
10515 *) When opening "configuration" files (like httpd.conf, htaccess
10516 and htpasswd), Apache will not allow them to be non-/dev/null
10517 device files. This closes a DoS hole. At the same time,
10518 we use ap_pfopen to open these files to handle timeouts.
10519 [Jim Jagielski, Martin Kraemer]
10521 *) Apache will now log the reason its httpd children exit if they exit
10522 due to an unexpected signal. (It requires a new porting define,
10523 SYS_SIGLIST, which if defined should point to a list of text
10524 descriptions of the signals available. See PORTING.) [Dean Gaudet]
10526 *) WIN32: chdir() doesn't make sense in a multithreaded environment
10527 like WIN32. Before, Win32 CGI's could have had sporadic failures
10528 if a chdir call from one thread was made between another chdir call
10529 and a spawn in another thread. So, for now don't chdir for CGI scripts
10530 in WIN32. The current CGI "spec" is unclear as to whether it's
10531 necessary. Long-term fix is to either serialize the chdir/spawn combo
10532 or use WIN32 native calls to spawn a process. This temp fix was
10533 necessary to remove this as a showstopper for 1.3's release.
10536 *) Cleanup the suEXEC support in APACI and make it more safe:
10537 1. Add big fat hint in INSTALL about risks and to read the
10538 htdocs/manual/suexec.html document before using the suexec-related
10540 2. Make sure the user has at least provided one --suexec-xxxx option
10541 (specifies suEXEC parameters) in addition to --enable-suexec option.
10542 If only --enable-suexec is given APACI stops with a hint to INSTALL
10543 and htdocs/manual/suexec.html documents.
10544 3. Provide two additional --suexec-xxxx options to make the suEXEC
10545 configuration complete (especially for package maintainers who else
10546 had to patch the source tree) by providing ways to configure minimal
10547 UID/GID and safe PATH, too.
10548 [Ralf S. Engelschall]
10550 *) Cleanup of the `configure --shadow' process:
10551 - make sure the configure script creates its temporary files in the
10552 shadow tree to avoid conflicts with parallel configure runs
10553 - removed unnecessary option "-r" from "rm" call for Makefiles
10554 - make sure the configure scripts creates the shadow-wrapper Makefile
10555 only when no shadow trees already exists
10556 - make sure "make distclean" removes the shadow-wrapper Makefile but only
10557 when no more shadow trees exists
10558 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
10559 as fast (in the past it needed 70sec, now it runs just 38sec)
10560 - make sure CVS does not complain about the created files
10561 Makefille.<gnutriple> and directories src.<gnutriple>
10562 [Ralf S. Engelschall]
10564 *) Added the ap_add_version_component() API routine and the
10565 AddVersionPlatform core directive. The first allows modules to
10566 declare themselves in the Server response header field value,
10567 augmenting the SERVER_SUBVERSION define in the Configuration file
10568 with run-time settings (more useful in a loadable-module environment).
10569 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
10570 into the server version string. [Ken Coar] PR#2056
10572 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
10575 *) Emit the "Accept-Range" header for the default handler.
10576 [Brian Behlendorf] PR#1464
10578 *) Add a note to httpd.conf-dist that apache will on some systems fail
10579 to start when the Group # is set to a negative or large positive value.
10582 *) Make sure the module execution order is correct even when some modules
10583 are loaded under runtime (`LoadModule') via the DSO mechanism:
10584 1. The list of loaded modules is now a dynamically allocated one
10585 and not the original statically list from modules.c
10586 2. The loaded modules are now correctly setup by LoadModule for
10587 later use by the AddModule command.
10588 3. When the DSO mechanism for modules is used APACI's `install'
10589 target now enables all created `LoadModule' lines per default because
10590 this is both already expected by the user _and_ needed to avoid
10591 confusion with the next point and reduces the Makefile.tmpl complexity
10592 4. When the DSO mechanism for modules is used, APACI's `install'
10593 target now additionally makes sure the module list is reconstructed
10594 via a complete `ClearModuleList+AddModule...' entry.
10595 5. The support tool `apxs' now also makes sure an AddModule command
10596 is added in addition to the LoadModule command.
10597 6. The modules.c generation was extended to now contain two
10598 comments to make sure no one is confused by the confusing terminology
10599 of loading/linking (we use load=link+load & link=activate instead of
10600 the obvious load=activate & link=link :-( )
10601 This way now there is no longer a difference under execution time between
10602 statically and dynamically linked modules.
10603 [Ralf S. Engelschall]
10605 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
10606 Big Symbol Renaming. [Ralf S. Engelschall]
10608 *) Add a comment to mod_example.c showing the format of a FLAG command
10609 handler. [Ken Coar]
10611 *) Standardized the time format in mod_status to match that of other
10612 places in the code (e.g. DATE_GMT). PR#1551
10614 *) Fix handling of %Z in timefmt strings for those platforms with no time
10615 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
10618 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
10619 feature compatible with 'UseCanonicalName off' by changing
10620 r->server->server_hostname to ap_get_server_name(). And I changed some
10621 functions which use r->server->port to use ap_get_server_port() instead,
10622 because if there's no Port directive in the config r->server->port is 0.
10625 *) get/set_module_config are trivial enough to be better off inline. Worth
10626 1.5% performance boost. [Dean Gaudet]
10628 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
10629 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
10632 *) [BS2000 security] BS2000 needs an extra authentication to initialize
10633 the task environment to the unprivileged User id. Otherwise CGI scripts
10634 would have a way to gain super user access. [Martin Kraemer]
10636 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
10637 absolute path, only log base name of logging source as is done
10638 in unix. [Martin Kraemer]
10640 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
10641 the encoding type from the Accept-Encoding header (if it's there)
10642 and use it in the response, as that's probably what it'll be expecting.
10643 [<Ronald.Tschalaer psi.ch>]
10645 *) Fix to mod_alias: translate_alias_redir is dealing with
10646 a URI, not a filename, so the check for drive letters for win32
10647 and emx is not necessary. [Dean Gaudet]
10649 *) WIN32: Allow .cmd as an executable extension.

10655 *) Child processes can now "signal" (by exiting with a status
10656 of APEXIT_CHILDFATAL) the parent process to abort and
10657 shutdown the server if the error in the child process was
10658 fatal enough. [Jim Jagielski]

10661 [Jim Jagielski] PR#2112

10672 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
10673 Additionally the checks for finding the vendor DSO library were moved
10674 from mod_so.c to Configure because first it needs $PLAT etc. and second
10675 mod_so already uses an abstraction layer and does not fiddle with the
10676 vendor functions itself.

10679 *) PORT: Some optimization defines for NetBSD
10680 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
10682 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
10683 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
10685 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
10686 AIX variants should work fine, too. Even AIX 3.x should work). This is
10687 accomplished by using the free DSO emulation code from Jens-Uwe Mager
10688 which we put into a os/unix/os-dso-aix.c file.
10689 [Ralf S. Engelschall]
10691 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
10692 that we should use NET_SIZE_T == int but the include files force size_t.
10693 [Ralf S. Engelschall]
10695 *) Fix two bugs in select() handling in http_main.c.
10698 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
10699 is unset (as it is in situations like timeouts) where it is unclear
10700 whether errno is set or not. [Martin Kraemer]
10702 *) Just having APACI's localstatedir is too general and not enough for most
10703 of the systems. 1.3b6 again required manual APACI patches by package
10704 maintainers from Red Hat and FreeBSD because for their filesystem layout a
10705 little bit more flexibility in configuring the paths is needed. Hence we
10706 provide three additional configure options (--runtimedir, --logfiledir,
10707 --proxycachedir) which now can be used for more granular adjustments if
10708 --localstatedir is not enough to fit the particular needs. As a nice
10709 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
10710 [Ralf S. Engelschall]
10712 *) Make the install root for "make install" in APACI's Makefile overrideable
10713 by package authors. This way we are even more friendly to package
10714 maintainers (especially Debian and Red Hat) who build for the real prefix
10715 via "configure --prefix=/<real>" but use a different local prefix via
10716 "make root=/tmp/apache install" for rolling the package without bristling
10717 the target location on their system.
10718 [Ralf S. Engelschall]
10720 *) Workaround sed limitations in APACI's configure script by now
10721 substituting in chunks of 50 commands (because for instance HPUX's vendor
10722 sed has a limit of max. 98 commands)
10723 [Ralf S. Engelschall] PR#2136
10725 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
10726 [Ralf S. Engelschall] PR#2140
10728 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG

10730 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
10731 [Ralf S. Engelschall]
10733 *) Workaround braindead AWK's when generating ap_config.h: The split() and
10734 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
10735 [Ralf S. Engelschall] PR#2139
10737 *) Various bugfixes and cleanups for the APACI configure script:
10738 o fix IFS handling for _nested_ situation
10739 o fix Perl interpreter search: take first one found instead of last one
10740 o fix DSO consistency check
10741 o print error messages to stderr instead of stdout
10742 o add install-quiet for --shadow situation to Makefile stub
10743 o reduce complexity by avoiding sed-hacks for rule and module list loops
10744 [Ralf S. Engelschall]
10746 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
10748 *) Make sure the input field separator (IFS) shell variable is explicitly
10749 initialized correctly before _every_ `for' loop and also restored after
10750 the loops. [Ralf S. Engelschall]
10752 *) Make sure that "make install" doesn't overwrite the `mime.types' and
10753 `magic' files from an existing Apache installation. Because people often
10754 customize these for own MIME and content types.
10755 [Ralf S. Engelschall]

10761 [Ralf S. Engelschall] PR#2105
10763 *) Let "configure" clear out the users parameters (provided as shell

10768 *) Provide backward compatibility from some old src/Configuration.tmpl
10769 parameter names to the canonical Autoconf-style shell variable names. For

10777 *) Make `configure --compat' more "compatible" by first
10778 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and

10792 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
10794 *) If you start apache with the -S command line option it will dump

10796 to figure out what is wrong with their vhost configuration.
10797 (Other dumps may be added in the future.) [Dean Gaudet]
10799 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
10800 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
10803 *) Because /usr/local/apache is the default prefix the ``configure
10804 --compat'' option no longer has to set prefix, again. This way the
10805 --compat option honors a leading --prefix option. [Lars Eilebrecht]
10807 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
10808 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
10809 to avoid "discard const" warnings. [Ralf S. Engelschall]
10811 *) If a specific handler is set for a file yet the request still
10812 ends up being handled by the default handler, log an error
10813 message before handling it. This catches things such as trying
10814 to use SSIs without mod_include enabled. [Marc Slemko]
10816 *) Fix error logging for the startup case where ap_log_error() still uses
10817 stderr as the target. Now the default log level is honored here, too.
10818 [Ralf S. Engelschall]

10827 Changes with Apache 1.3b6
10829 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
10831 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
10832 interface via the similar but proprietary HP/UX shl_xxx-style system
10833 calls. [Ralf S. Engelschall]
10835 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
10836 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
10837 Make. [Ralf S. Engelschall]
10839 *) ++++ THE BIG SYMBOL RENAMING ++++
10840 To avoid symbol clashes with third-party code compiled into the server,
10841 we globally applied the prefix "ap_" to the following classes of
10843 - Apache provided general functions (e.g., ap_cpystrn)
10844 - Public API functions (e.g., palloc, bgets)
10845 - Private functions which we can't make static (because of
10846 cross-object usage) but should be (e.g., new_connection)
10847 For backward source compatibility a new header file named compat.h was
10848 created which provides defines for the old symbol names and can be used
10849 by third-party module authors.
10852 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
10853 problem under SVR4 is that there is no command flag to force the linker
10854 to export the global symbols of the httpd executable therewith they are
10855 available to the DSO's. Instead of problematic hacks like creating a
10856 dummy.so file (containing dummy references to all global symbols) the
10857 httpd binary is linked against, we use a clean trick stolen from Perl 5:
10858 Placing the Apache core code itself into a DSO library named libhttpd.so.
10859 This way the global symbols _HAVE_ to be exported and thus are available
10860 to any manually loaded DSO's under runtime. To reduce the impact to the
10861 user to null we go even further and create a stub httpd executable which
10862 automatically keeps track of the DSO library loading itself and thus
10863 hides the complete mechanism from the user. Although the generation of
10864 this DSO library is automatically triggered for platforms which
10865 essentially need it (mostly all SVR4-derivates) it can be also enabled
10866 manually via the Rule SHARED_CORE. This can be interesting in the future
10867 where we perhaps exploit this libhttpd.so mechanism for providing nifty
10868 features like graceful upgrades, or whatever.
10869 [Ralf S. Engelschall, Martin Kraemer]
10871 *) Build the libraries before building the rest of the tools. [Ben Hyde]
10873 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
10874 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
10875 conventions while "clean" removes only stuff created by "all" targets,
10876 "distclean" additionally removes the stuff from the configuration
10877 process. This way "make distclean" (hence the name) provides a fresh
10878 source tree as it was for distribution.
10879 [Ralf S. Engelschall]
10881 *) Allow top-level (APACI) Makefile to break on build errors
10882 the same way the src/ subtree Makefiles breaks on them by replacing the
10883 initial APACI sed-subdir-display-kludge with a more clean
10884 variable-passing-solution: variable SDP can optionally hold the subdir
10885 prefix which is consistently used for displaying the subdir movement.
10886 This way even the top-level Makefile can stop correctly on errors as the
10887 user expects. [Ralf S. Engelschall]

10894 remove #define IS_MODULE from modules and add SHARED_MODULE define
10895 to the mak/dsp files. [Alexei Kosut]
10897 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
10898 since we are now logging APLOG_WARNING by default. [Roy Fielding]
10900 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
10902 *) Add documentation file and src/Configuration.tmpl entry for the
10903 experimental mod_mmap_static module. Because although it is and marked as
10904 an experimental one it is distributed and thus should be documented and
10905 prepared for configuration the same way as all others modules.
10906 [Ralf S. Engelschall]
10908 *) Add query (-q) option to apxs support tool to be able to manually query
10909 specific settings from apxs. This is needed for instance when you
10910 manually want to access Apache's header files and you need to assemble
10911 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
10912 [Ralf S. Engelschall]
10914 *) Now src/Configure uses a fallback strategy for the shared object support
10915 on platforms where no explicit information is available: If a Perl
10916 installation exists we ask it about its shared object support and if it's
10917 the dlopen-style one we shamelessly guess the compiler and linker flags
10918 for creating shared objects from Perls knowledge. Of course, the user is
10919 warning about what we are doing and informed that he should send us
10920 the guessed flags when they work. [Ralf S. Engelschall]
10922 *) Provide APACI --without-support option to be able to disable the build
10923 and installation of the support tools from the src/support/ area.
10924 Although its useful to have these installed per default we should provide
10925 a way to compile and install without them for backward-compatibility.
10926 [Ralf S. Engelschall]
10928 *) Add of the new APache eXtenSion (apxs) support tool for building and
10929 installing modules into an _already installed_ Apache package through the
10930 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
10931 this approach actually doesn't need the Apache source tree. The
10932 (APACI-installed) server package is enough, because this now includes the
10933 Apache C header files (PREFIX/include) and the new APXS tool
10934 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
10935 module authors to build their Apache modules _OUTSIDE_ the Apache source
10936 tree while avoiding them to fiddle around with the totally platform
10937 dependend way of compiling DSO files. The tool supports all ranges of
10938 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
10939 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
10940 on-the-fly generate a minimalistic Makefile and sample module for the
10941 first step to provide both a quick success event and to demonstrate the
10942 APXS mechanism to module authors. [Ralf S. Engelschall]
10944 *) Fix core dumps in use of CONNECT in proxy.
10945 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
10947 *) Modify the log directives in httpd.conf-dist files to use CustomLog
10948 so that users have examples of how CustomLog can be used.
10951 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
10952 the Apache distribution tree. Until Apache 1.3 there was no real
10953 out-of-the-box batch-capable build and installation procedure for the
10954 complete Apache package. This is now provided by a top-level "configure"
10955 script and a corresponding top-level "Makefile.tmpl" file. The goal is
10956 to provide a GNU Autoconf-style frontend which is capable to both drive
10957 the old src/Configure stuff in batch and additionally installs the
10958 package with a GNU-conforming directory layout. Any options from the old
10959 configuration scheme are available plus a lot of new options for flexibly
10960 customizing Apache. [Ralf S. Engelschall]
10962 *) The floating point ap_snprintf code wasn't threadsafe.
10963 Had to remove the HAVE_CVT macro in order to do threadsafe
10964 calling of the ?cvt() floating point routines. [Dean Gaudet]
10966 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962

10971 *) BUG: Configure was using TCC and CC inconsistently. Make sure
10972 Configure knows which CC we are using. [Jim Jagielski]
10974 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
10975 was defined in a parent directory. [Lars Eilebrecht]
10977 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
10978 a generic printf-style routine that can call arbitrary output
10979 routines. Use this to replace http_bprintf.c. Add new routines
10980 psprintf(), pvsprintf() which allocate the exact amount of memory
10981 required for a string from a pool. Use psprintf() to clean up
10982 various bits of code which used ap_snprintf()/pstrdup().
10985 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
10986 ap_snprintf() has different semantics and formatting codes than
10987 snprintf(). [Dean Gaudet]
10989 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
10990 is necessary on at least Solaris where the /etc/rc?.d scripts
10991 are run with these signals ignored, and "SIG_IGN" settings are
10992 maintained across exec().

11017 properly marked for closure on fork().
11018 [Jürgen Keil <jk tools.de>] PR#2000
11020 *) Allow %2F in two situations: 1) it is in the query part of the URI,
11021 therefore not exposed to %2F -> '/' translations and 2) the request
11022 is a proxy request, so we're not dealing with a local resource anyway.
11023 Without this, the proxy would fail to work for any URL's with
11024 %2f in them (occurs quite often in
11025 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
11027 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
11029 *) Make the shared object compilation command more portable by avoiding
11030 the direct combination of `-c' & `-o' which is not honored by some
11031 compilers like UnixWare's cc. [Ralf S. Engelschall]
11033 *) WIN32: the proxy was creating filenames missing the last four
11034 characters. While this normally doesn't stop anything from
11035 working, it can result in extra collisions.
11036 [Tim Costello <tjcostel socs.uts.edu.au>] PR#1890
11038 *) Now mod_proxy uses the response string (in addition to the response status
11039 code) from the already used FTP SIZE command to setup the Content-Length
11040 header if available. [Ralf S. Engelschall] PR#1183
11042 *) Reanimated the (still undocumented) proxy receive buffer size directive:
11043 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
11044 name was really too generic, added documentation for this directive to
11045 the mod_proxy.html and corrected the hyperlink to it in the

11049 faster [Martin Kraemer]
11051 *) Make Configure die when you give it an unknown command switch.
11054 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
11055 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
11056 and per default compiled support programs have manual pages - just to
11057 document our stuff a little bit more and to be able to do really
11058 Unix-like installations ;-) [Ralf S. Engelschall]
11060 *) Major cleanups to the Configure script to make it and its generated
11061 Makefiles again readable and maintainable: add SRCDIR option, removed
11062 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
11063 generated sections, consequently added Makefile headers with inheritance
11064 information, added subdir movement messages for easier following where
11065 the build process currently stays (more verbose then standard Make, less
11066 verbose than GNU make), same style to comments in the Configure script,
11067 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
11069 *) Add the new ApacheBench program "ab" to src/support/: This is derived
11070 from the ZeusBench benchmarking program and can be used to determine the
11071 response performance of an Apache installation. This version is
11072 officially licensed with Zeus Technology, Ltd. See the license agreement

11074 [Ralf S. Engelschall]
11076 *) API: Various core functions that are definately not part of the API
11077 have been made static, and a few have been marked API_EXPORT. Still
11078 more have been marked CORE_EXPORT and are not intended for general
11079 use by modules. [Doug MacEachern, Dean Gaudet]
11081 *) mod_proxy was not clearing the Proxy-Connection header from
11082 requests; now it does. This did not violate any spec, however
11083 causes poor interactions when you are talking to remote proxies.
11084 [Marc Slemko] PR#1741

11089 *) cfg_getline() was not properly handling lines that did not end
11090 with a line termination character. [Marc Slemko] PR#1869, 1909
11092 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
11094 *) Clean up some undocumented behavior of mod_setenvif related to
11095 "merging" two SetEnvIf directives when they match the same header
11096 and regex. Document that mod_setenvif will perform comparisons in
11097 the order they appear in the config file. Optimize mod_setenvif by
11098 doing more work at config time rather than at runtime.
11101 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
11102 to allow for modules to overrule them and to reduce redefinition
11103 warnings [Jim Jagielski]
11105 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
11108 *) Making the hard-coded cross-module function call mime_find_ct() (from
11109 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
11110 checking is really called even for proxy requests except for URLs with
11111 HTTP schemes (because there we can optimize by not running the type
11112 checking hooks due to the fact that the proxy gets the MIME Content-type
11113 from the remote host later). This change cleans up mod_mime by removing
11114 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
11115 especially unbundles mod_proxy and mod_mime. This way they both now can
11116 be compiled as shared objects and are no longer tied together.
11117 [Ralf S. Engelschall]
11119 *) util.c cleanup and speedup. [Dean Gaudet]
11121 *) API: Clarification, pstrndup() will always copy n bytes of the source
11122 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
11124 *) Mark module command_rec and handler_rec structures const so that they
11125 end up in the read-only data section (and are friendlier to systems
11126 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
11128 *) Add check to the "Port" directive to make sure the specified
11129 port is in the appropriate range. [Ben Hyde]
11131 *) Performance improvements to invoke_handler().
11132 [Dmitry Khrustalev <dima bog.msu.su>]
11134 *) Added support for building shared objects even for library-style modules
11135 (which are built from more than one object file). This now provides the
11136 ability to build mod_proxy as a shared object module. Additionally
11137 modules like mod_example are now also supported for shared object
11138 building because the generated Makefiles now no longer assume there is at
11139 least one statically linked module. [Ralf S. Engelschall]
11141 *) API: Clarify usage of content_type, handler, content_encoding,
11142 content_language and content_languages fields in request_rec. They
11143 must always be lowercased; and the strings pointed to shouldn't
11144 be modified (you must copy them to modify them). Fix a few bugs
11145 related to this. [Dean Gaudet]
11147 *) API: Clarification: except for RAW_ARGS, all command handlers can
11148 treat the char * parameters as permanent, and modifiable. There
11149 is no need to pstrdup() them. Clean up some needless pstrdup().
11152 *) Now mod_so keeps track of which module shared objects with which names
11153 are loaded and thus avoids multiple loading and unloading and irritating
11154 error_log messages. [Ralf S. Engelschall]
11156 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
11157 environment variable in the apache core. But that tweaking interferes
11158 with mod_setenv. So don't tweak if the user has specified an explicit
11159 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888
11161 *) rputs() did not calculate r->sent_bodyct properly.
11162 [Siegmund Stirnweiss <siegst kat.ina.de>] PR#1900
11164 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's

11166 it to the IP address when unavailable.
11167 [Tony Finch <fanf demon.net>] PR#1925
11169 *) Various improvements to the configuration and build support for compiling
11170 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
11171 OSF1 support with GCC and vendor compilers was added. This way shared
11172 object support is now provided out-of-the-box for FreeBSD, Linux,
11173 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
11174 [Ralf S. Engelschall]
11176 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
11177 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
11178 and USE_OS2_SCOREBOARD. [Dean Gaudet]
11180 *) Fix one more special locking problem for RewriteMap programs in
11181 mod_rewrite: According to the documentation of flock(), "Locks are on
11182 files, not file descriptors. That is, file descriptors duplicated
11183 through dup(2) or fork(2) do not result in multiple instances of a lock,
11184 but rather multiple references to a single lock. If a process holding a
11185 lock on a file forks and the child explicitly unlocks the file, the
11186 parent will lose its lock.". To overcome this we have to make sure the
11187 RewriteLock file is opened _AFTER_ the childs were spawned which is now
11188 the case by opening it in the child_init instead of the module_init API
11189 hook. [Ralf S. Engelschall] PR#1029
11191 *) Change to Location and LocationMatch semantics. LocationMatch no
11192 longer lets a single slash match multiple adjacent slashes in the
11193 URL. This change is for consistency with RewriteRule and
11194 AliasMatch. Multiple slashes have meaning in URLs that they do
11195 not have in (some) filesystems. Location on the other hand can
11196 be considered a shorthand for a more complicated regex, and it
11197 does match multiple slashes with a single slash -- which is
11198 also consistent with the Alias directive.
11199 [Dean Gaudet] related PR#1440
11201 *) Fix bug with mod_mime_magic causing certain files, including files
11202 of length 0, to result in no response from the server.
11205 *) The Configure script now generates src/include/ap_config.h which
11206 contains the set of defines used when Apache is compiled on a platform.
11207 This file can then be included by external modules before including
11208 any Apache header files in case they are being built separately from
11209 Apache. Along with this change, a couple of minor changes were
11210 made to make Apache's #defines coexist peacefully with any autoconf
11211 defines an external module might have. [Rasmus Lerdorf]
11213 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
11214 but without any RewriteXXXXX directives. Here mod_rewrite is given no
11215 chance by the API to initialize its per-server configuration and thus
11216 receives the wrong one from the main server. This is now avoided by
11217 remembering the server together with the config structure while
11218 configuring and later assuming there is no config when we see a
11219 difference between the remembered server and the one calling us.
11220 [Ralf S. Engelschall] PR#1790
11222 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
11223 is automatically disabled under configure time when the dbm_xxx functions
11224 are not available. Second, two heavy source code errors in the DBM
11225 support code were fixed. This makes DBM RewriteMap's usable again after
11226 a long time of brokenness. [Ralf S. Engelschall] PR#1696
11228 *) Now all configuration files support Unix-style line-continuation via
11229 the trailing backslash ("\") character. This enables us to write down
11230 complex or just very long directives in a more readable way. The
11231 backslash character has to be really the last character before the
11232 newline and it has not been prefixed by another (escaping) backslash.

11248 depending on the rev of Solaris and what mixture of modules
11249 are in use. So it has been disabled, and Solaris is back to
11250 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
11251 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
11252 up static content only servers. Or it may fail unpredictably.

11255 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
11258 *) API: Rewrite of absoluteURI handling, and in particular how
11259 absoluteURIs match vhosts. Unless a request is a proxy request, a
11260 "http://host" url is treated as if a similar "Host:" header had been
11261 supplied. This change was made to support future HTTP/1.x protocols
11262 which may require clients to send absoluteURIs for all requests.
11264 In order to achieve this change subtle changes were made to the API. In a
11265 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
11266 that the unmodified uri can be retrieved easily. r->proxyreq is not set
11267 by the core, modules must set it during the post_read_request or
11268 translate_names phase.
11270 Plus changes to the virtualhost test suite for absoluteURI testing.
11272 This fixes several bugs with the proxy proxying requests to vhosts
11273 managed by the same httpd.

11294 *) API: A new source module main/util_uri.c; It contains a routine
11295 parse_uri_components() and friends which breaks a URI into its component
11296 parts. These parts are stored in a uri_components structure called
11297 parsed_uri within each request_rec, and are available to all modules.
11298 Additionally, an unparse routine is supplied which re-assembles the URI
11299 components back to an URI, optionally hiding the username:password@ part
11300 from ftp proxy requests, and other useful routines. Within the structure,
11301 you find on a ready-for-use basis:
11302 scheme; /* scheme ("http"/"ftp"/...) */
11303 hostinfo; /* combined [user[:password]@]host[:port] */
11304 user; /* user name, as in http://user:passwd@host:port/ */
11305 password; /* password, as in http://user:passwd@host:port/ */
11306 hostname; /* hostname from URI (or from Host: header) */
11307 port_str; /* port string (integer representation is in "port") */
11308 path; /* the request path (or "/" if only scheme://host was given) */
11309 query; /* Everything after a '?' in the path, if present */
11310 fragment; /* Trailing "#fragment" string, if present */
11311 This is meant to serve as the platform for *BIG* savings in
11312 code complexity for the proxy module (and maybe the vhost logic).
11315 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and

11354 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
11356 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
11357 type but with a special post-processing for the looked-up value: It
11358 parses it into alternatives according to `|' chars and then only one
11359 particular alternative is chosen randomly (this is an essential
11360 functionality needed for balancing between backend-servers when using
11361 Apache as a Reverse Proxy. The looked up value here is a list of
11362 servers). Second, `int' with the built-in maps named `tolower' and
11363 `toupper' which can be used to map URL parts to a fixed case (this is an
11364 essential feature to fix the case of server names when doing mass
11365 virtual-hosting with the help of mod_rewrite instead of using
11366 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
11367 Jay Soffian <jay cimedia.com>] PR#1631
11369 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
11370 This directive lets Apache adjust the URL in Location-headers on HTTP
11371 redirect responses sent by the remote server. This way the virtually
11372 mapped area is no longer left on redirects and thus by-passed which is
11373 especially essential when running Apache as a reverse proxy.

11391 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
11392 In particular the handlers could trigger themselves into an infinite

11433 semantics (* does not match /). To fix this, <Files> now
11434 apply only to the basename of the request filename. This

11444 result in an infinite loop. It seems these two tickle kernel
11445 or library bugs occasionally, and result in log spammage and
11446 a generally bad scene. Now the child exits immediately,

11482 configuration files. [Lars Eilebrecht]
11484 *) MiNT port update. [Jan Paul Schmidt]
11486 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
11487 equivalent, similarly for x-compress and compress. Apache
11488 now ignores a leading x- when comparing encodings. It also
11489 preserves the encoding the client requests (for example if
11490 it requests x-gzip, then Apache will respond with x-gzip
11491 in the Content-Encoding header).

11494 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
11496 *) Added mod_so module to support dynamic loading of modules on Unix
11497 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule

11501 *) Minor cleanups to r->finfo handling in some modules.
11504 *) Abstract read()/write() to ap_read()/ap_write().
11505 Makes it easier to add other types of IO code such as SFIO.

11509 different protocols easier. [Ben Laurie, Randy Terbush]
11511 *) There are many cases where users do not want Apache to form
11512 self-referential urls using the "canonical" ServerName and Port.
11513 The new UseCanonicalName directive (default on), if set to off

11519 PR#315, 459, 485, 1433
11521 *) Yet another rearrangement of the source tree.. now all the common
11522 header files are in the src/include directory. The -Imain -Iap
11523 references in Makefiles have been changed to the simpler -Iinclude
11524 instead. In addition to simplifying the build a little bit, this
11525 also makes it clear when a module is referencing something in a
11526 other than kosher manner (e.g., the proxy including mod_mime.h).
11527 Module-private header files (the proxy, mod_mime, the regex library,
11528 and mod_rewrite) have not been moved to src/include; nor have
11529 the OS-abstraction files. [Ken Coar]
11531 *) Fix a bug where r->hostname didn't have the :port stripped
11532 from it. [Dean Gaudet]
11534 *) Tweaked the headers_out table size, and the subprocess_env
11535 table size guess in rename_original_environment(). Added
11536 MAKE_TABLE_PROFILE which can help discover make_table()
11537 calls that use too small an initial guess, see alloc.c.
11540 *) Options and AllowOverride weren't properly merging in the main
11541 server setting inside vhosts (only an issue when you have no
11542 <Directory> or other section containing an Options that affects
11543 a request). Options +foo or -foo in the main_server wouldn't
11544 affect the main_server's lookup defaults. [Dean Gaudet]
11546 *) Variable 'cwd' was being used pointlessly before being set.
11549 *) r->allowed handling cleaned up in the standard modules.
11552 *) Some case-sensitivity issues cleaned up to be consistent with
11553 RFC2068. [Dean Gaudet]
11555 *) SIGURG doesn't exist everywhere.
11556 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
11558 *) mod_unique_id was erroneously generating a second unique id when
11559 an internal redirect occured. Such redirects occur, for example,
11560 when processing a DirectoryIndex match. [Dean Gaudet]
11562 *) API: table_add, table_merge, and table_set include implicit pstrdup()
11563 of the key and value. But in many cases this is not required
11564 because the key/value is a constant, or the value has been built
11565 by pstrcat() or other similar means. New routines table_addn,
11566 table_mergen, and table_setn have been added to the API, these
11567 routines do not pstrdup() their arguments. The core code and
11568 standard modules were changed to take advantage of these routines.
11569 The resulting server is up to 20% faster in some situations.
11571 Note that it is easy to get code subtly wrong if you pass a key/value
11572 which is in a pool other than the pool of the table. The only
11573 safe thing to do is to pass key/values which are in the pool of
11574 the table, or in one of the ancestors of the pool of the table.
11575 i.e. if the table is part of a subrequest, a value from the main
11576 request's pool is OK since the subrequest pool is a sub_pool of the
11577 main request's pool (and therefore has a lifespan at most as long as
11578 the main pool). There is debugging code which can detect improper
11579 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
11580 [Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet]
11582 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
11583 which don't exist on disk more gracefully; handles vhosts properly.
11584 Update documentation to reflect the code -- if there's no
11585 MimeMagicFile directive then the module is not enabled.
11588 *) PORT: Some older *nix dialects cannot automatically start scripts
11589 which begin with a #! interpreter line (the shell starts the scripts
11590 appropriately on these platforms). Apache now supports starting of
11591 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
11592 [Martin Kraemer, with code from Peter Wemm <peter zeus.dialix.oz.au>
11595 *) API: "typedef array_header table" removed from alloc.h, folks should
11596 have been writing to use table as if it were an opaque type, but even
11597 some standard modules got this wrong. By changing the definition
11598 to "typedef struct table table" module authors will receive compile
11599 time warnings that they're doing the wrong thing. This change
11600 facilitates future changes with more sophisticated table
11601 structures. Specifically, module authors should be using table_elts()
11602 to get access to an array_header * for the table. [Dean Gaudet]
11604 *) API: Renamed new_connection() to avoid namespace collision with LDAP
11605 library routines. [Ken Coar, Rasmus Lerdorf]
11607 *) WIN32: mod_speling is now available on the Win32 platform.
11610 *) For clarity the following compile time definition was changed:
11612 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
11614 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
11615 and not be a general notice that the OS has mmap(). Now the
11616 HAVE_MMAP/SHMGET #defines strictly are informational that the
11617 OS has that method of shared memory; the type to use for
11618 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
11619 and USE_SHMGET_SCOREBOARD). This allows outside modules to
11620 determine if shared memory is available and allows Apache
11621 to determine the best method to use for the scoreboard.
11624 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
11625 as do various earlier versions. It should be safe on all versions.
11626 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
11627 the slack code. A few other cleanups for Unixware.

11650 The choice of flock vs. fcntl was made based on timings which showed that
11651 even on non-NFS, non-exported filesystems fcntl() was an order of
11652 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
11653 that single socket users will see no difference. [Dean Gaudet] PR#467

11675 *) Some const declarations in mod_imap.c that were added for debugging
11676 purposes caused some compilers heartburn without adding any
11677 significant value, so they've been removed. [Ken Coar]
11679 *) The src/main/*.h header files have had #ifndef wrappers added to
11680 insulate them against duplicate calls if they get included through
11681 multiple paths (e.g., in .c files as well as other .h files).
11684 *) The libap routines now have a header file for their prototypes,
11685 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
11687 *) mod_autoindex with a plaintext header file would emit the <PRE>
11688 start-tag before the HTML preamble, rather than after the preamble
11689 but before the header file contents. [John Van Essen <jve gamers.org>]
11692 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
11693 only an issue on systems without a MAXDNAME define or where
11694 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
11696 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
11697 is used to read various types of files such as htaccess and
11698 htpasswd files. [Marc Slemko]
11700 *) SECURITY: Ensure that the buffer returned by ht_time is always
11701 properly null terminated. [Marc Slemko]
11703 *) The "Connection" header could be sent back with multiple "close"
11704 tokens. Not an error, but a waste.

11707 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
11708 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
11710 *) "basic" auth needs a case-insensitive comparison.
11711 [<Ronald.Tschalaer psi.ch>] PR#1666
11713 *) For maximum portability, the environment passed to CGIs should
11714 only contain variables whose names match the regex
11715 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
11716 underscores over any character outside the regex. This
11717 affects HTTP_* variables, in a way that should be backward
11718 compatible for all the standard headers; and affects variables
11719 set with SetEnv/BrowserMatch and similar directives.

11806 [Ben Reser <breser regnow.com>] PR#1366
11808 *) The bputc() macro was not properly integrated with the chunking
11809 code; in many cases modules using bputc() could cause completely
11810 bogus chunked output. (Typically this will show up as problems
11811 with Internet Explorer 4.0 reading a page, but other browsers
11812 having no problem.) [Dean Gaudet]
11814 *) Create LARGE_WRITE_THRESHOLD define which determines how many
11815 bytes have to be supplied to bwrite() before it will consider
11816 doing a writev() to assemble multiple buffers in one system
11817 call. This is critical for modules such as mod_include,
11818 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
11819 strings in some cases. The result would be extra effort
11820 setting up writev(), and in many cases extra effort building
11821 chunks. The default is 31, it can be overriden at compile
11822 time. [Dean Gaudet]

11855 at the 256th byte as well. Fixed. [Dean Gaudet]

11887 *) WIN32: Cure file leak in CGIs. [Peter Tillemans <pti net4all.be>] PR#1523
11889 *) proxy_ftp: the directory listings generated by the proxy ftp module
11890 now have a title in which the path components are clickable and allow
11891 quick navigation to the clicked-on directory on the currently listed
11892 ftp server. This also fixes a bug where the ".." directory links would
11893 sometimes refer to the wrong directory. [Martin Kraemer]

11908 *) WIN32: Work around brain-damaged spawn calls that can't deal
11909 with spaces and slashes. [Ben Laurie]
11911 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
11912 The problem was that certain undocumented environment variables
11913 needed for sockets to work under Win32 were not being passed.
11914 [Frank Faubert <frank sane.com>]
11916 *) Add a "-V" command line flag to the httpd binary. This
11917 flag shows some of the defines that Apache was compiled with.
11918 It is useful for debugging purposes. [Martin Kraemer]
11920 *) Start separating the ap_*() routines into their own library, so they
11921 can be used by items in src/support among other things.
11922 [Ken Coar] PR#512, 905, 1252, 1308
11924 *) Give a more informative error when no AuthType is set.
11927 *) Remove strtoul() use from mod_proxy because it isn't available
11928 on all platforms. [Marc Slemko] PR#1214
11930 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
11931 This turns out to be a bug in Winsock - select() doesn't always
11932 return the correct status. [Ben Laurie]
11934 *) Directives owned by http_core can now use the new check_cmd_context()
11935 routine to ensure that they're not being used within a container
11936 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
11938 *) PORT: Recent changes made it necessary to add explicit prototype
11939 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
11941 *) It was necessary to distinguish between resources which are
11942 allocated in the parent, for cleanup in the parent, and resources
11943 which are allocated in each child, for cleanup in each child.
11944 A new pool was created which is passed to the module child_init
11945 and child_exit functions; modules are free to register per-child
11946 cleanups there. This fixes a bug with reliable piped logs.
11949 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
11950 unless it was also doing FancyIndexes, but it displayed the
11951 HeaderName file at the top under all circumstances. It now shows
11952 the ReadmeName file for simple indices, too, as it should.
11955 *) http_core was mmap()ing even in cases where it wasn't going to
11956 read the file. [Ben Hyde <bhyde gensym.com>]
11958 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
11959 Now the rewriting engine (the heart of mod_rewrite) is organized more
11960 straight-forward, first time well documented and reduced to the really
11961 essential parts. All redundant cases were stripped off and processing now
11962 is the same for both per-server and per-directory context with only a
11963 minimum difference (the prefix stripping in per-dir context). As a
11964 side-effect some subtle restrictions and two recently discovered problems
11965 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
11966 context and restrictions on the substitution URL on redirects.
11967 Additionally some minor source cleanups were done.
11968 [Ralf S. Engelschall]
11970 *) Lars Eilebrecht wrote a whole new set of Apache Vhost Internals

11974 *) If ap_slack fails to allocate above the low slack line it's a good
11975 indication that further problems will occur; it's a better indication

11977 descriptors. So report it to the user once per restart.

12118 splits up a combined access log into separate files based on the
12119 name of the virtual host (listed first in the log records by "%v").
12122 Changes with Apache 1.3b2 (there is no 1.3b1)
12124 *) TestCompile was not passing $LIBS [Dean Gaudet]
12126 *) Makefile.tmpl was not using $CFLAGS in the link phase.
12129 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
12130 rudimentary memory debugger which can be used on live servers with
12131 low impact -- it sets all allocated and freed memory bytes to 0xa5.
12132 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
12133 and free() for each object. This is far more expensive and should
12134 only be used for testing with tools such as Electric Fence and
12135 Purify. See main/alloc.c for more details. [Dean Gaudet]
12137 *) Configure uses a sh trap and didn't set its exitcode properly.
12138 [Dean Gaudet] PR#1159
12140 *) Yet another vhost revamp. Add the NameVirtualHost directive which
12141 explicitly lists the ip:port pairs that are to be used for name-vhosts.
12142 From a given ip:port, regardless what the Host: header is, you can
12143 only reach the vhosts defined on that ip:port. The precedence of
12144 vhosts was reversed to match other precedences in the config --
12145 the earlier vhosts override the later vhosts. All vhost matching was
12146 moved into http_vhost.[ch]. [Dean Gaudet]
12148 *) ap_inline can be used to force inlining. GNUC __attribute__() can
12149 be used for whatever reason is appropriate (i.e. format() warnings
12150 for printf style functions). Both are enabled only with
12151 gcc >= 2.7.x (so that we have fewer support issues with older
12152 versions). [Dean Gaudet]
12154 *) Fix support for Proxy Authentication (we were testing the response
12155 status too early). [Marc Slemko]
12157 *) CoreDumpDirectory directive directs where the core file is
12158 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
12159 received. [Marc Slemko, Dean Gaudet]
12161 *) PORT: Support for Atari MINT.
12162 [Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
12164 *) When booting, apache will now detach itself from stdin, stdout,
12165 and stderr. stderr will not be detached until after the config
12166 files have been read so you will be able to see initial error
12167 messages. After that all errors are logged in the error_log.
12168 This makes it more convenient to start apache via rsh, ssh,
12169 or crontabs. [Dean Gaudet] PR#523
12171 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
12172 Also removed the auto-generated link to www.apache.org that was the
12173 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
12175 *) send_fb would not detect aborted connections in some situations.
12178 *) mod_include would use uninitialized data when parsing certain
12179 expressions involving && and ||. [Brian Slesinsky] PR#1139
12181 *) mod_imap should only handle GET methods. [Jay Bloodworth]
12183 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
12185 *) mod_autoindex improperly counted &escapes; as more than one
12186 character in the description. It also improperly truncated
12187 descriptions that were exactly the maximum length.
12190 *) RedirectMatch was not properly escaping the result (PR#1155). Also
12191 "RedirectMatch /advertiser/(.*) $1" is now permitted.
12194 *) mod_include now uses symbolic names to check for request success
12195 and return HTTP errors, and correctly handles all types of
12196 redirections (previously it only did temporary redirect correctly).
12197 [Ken Coar, Roy Fielding]
12199 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
12200 r->filename. Since those two are meant to be in sync with each other
12201 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
12203 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
12204 ["Kaufman, Steven E" <Steven.Kaufman unisys.com>]
12206 *) Inetd mode (which is buggy) uses timeouts without having setup the
12207 jmpbuffer. [Dean Gaudet] PR#1064
12209 *) Work around problem under Linux where a child will start looping
12210 reporting a select error over and over.
12211 [Rick Franchuk <rickf transpect.net>] PR#1107, 987, 588
12213 *) Fixed error in proxy_util.c when looping through multiple host IP
12214 addresses. [Lars Eilebrecht] PR#974
12216 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
12217 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
12218 bytes before writing, but it will never split a log entry across a
12219 buffer boundary. [Dean Gaudet]
12221 *) API: the short_score record has been split into two pieces, one which
12222 the parent writes on, and one which the child writes on. As part of
12223 this change the get_scoreboard_info() function was removed, and
12224 scoreboard_image was exported. This change fixes a race condition
12225 in file based scoreboard systems, and speeds up changes involving the
12226 scoreboard in earlier 1.3 development. [Dean Gaudet]
12228 *) API: New register_other_child() API (see http_main.h) which allows
12229 modules to register children with the parent for maintenance. It
12230 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
12232 *) API: New piped_log API (see http_log.h) which implements piped logs,
12233 and will use register_other_child to implement reliable piped logs
12234 when it is available. The reliable piped logs part can be disabled
12235 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
12236 logs is only available on Unix. [Dean Gaudet]
12238 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
12239 meets_conditions(). This allows conditional HTTP selection to be
12240 handled separately from the storing of the header fields, and provides
12241 the ability for CGIs to set their own ETags for conditional checking.
12242 [Ken Coar, Roy Fielding] PR#895
12244 *) Changes to mod_log_config to allow naming of format strings.
12245 Format nicknames are defined with "LogFormat fmt nickname", and can
12246 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
12249 *) New module, "mod_speling", which can help find files even when
12250 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
12252 *) API: New function child_terminate() triggers the child process to
12253 exit, while allowing the child finish what it needs to for the
12254 current request first.
12255 [Doug MacEachern, Alexei Kosut]
12257 *) Windows now defaults to using full status reports with mod_status.
12258 [Alexei Kosut] PR #1094
12260 *) *Really* disable all mod_rewrite operations if the engine is off.
12261 Some things (like RewriteMaps) were checked/performed even if they
12262 weren't supposed to be. [Ken Coar] PR #991
12264 *) Implement a new timer scheme which eliminates the need to call alarm() all
12265 the time. Instead a counter in the scoreboard for each child is used to
12266 show when the child has made forward progress. The parent samples this
12267 counter every scoreboard maintenance cycle, and issues SIGALRM if no
12268 progress has been made in the timeout period. This reduces the static
12269 request best-case syscall count to 22 from 29. This scheme is only
12270 used by systems with memory-based scoreboards. [Dean Gaudet]
12272 *) The proxy now properly handles CONNECT requests which are sent
12273 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
12275 *) A script called apachectl has been added to the support
12276 directory. This script allows you to do things such as
12277 "apachectl start" and "apachectl restart" from the command
12278 line. [Marc Slemko]
12280 *) Modules and core routines are now put into libraries, which
12281 simplifies the link line tremendously (among other advantages).
12284 *) Some of the MD5 names defined in Apache have been renamed to have
12285 an `ap_' prefix to avoid conflicts with routines supplied by
12286 external libraries. [Ken Coar]
12288 *) Removal of mod_auth_msql.c from the distribution. There are many
12289 other options for databases today. Rather than offer one option,
12290 offer none at this time. mod_auth_msql and other SQL database
12291 authentication modules can be found at the Apache Module Registry.
12292 http://modules.apache.org/ It would be nice to offer a generic
12293 mod_auth_sql option in the near future.
12295 *) PORT: BeOS support added [Alexei Kosut]
12297 *) Configure no longer accepts the -make option, since it creates
12298 Makefile on the fly based on Makefile.tmpl and Configuration.
12300 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
12301 of forcibly killing off all its processes and exiting without
12302 cleaning up. [Alexei Kosut]
12304 *) API: A new field in the request_rec, r->mtime, has been added to
12305 avoid gratuitous parsing of date strings. It is intended to hold
12306 the last-modified date of the resource (if applicable). An
12307 update_mtime() routine has also been added to advance it if
12308 appropriate. [Roy Fielding, Ken Coar]
12310 *) SECURITY: If a htaccess file can not be read due to bad permissions,
12311 deny access to the directory with a HTTP_FORBIDDEN. The previous
12312 behavior was to ignore the htaccess file if it could not be read.
12313 This change may make some setups with unreadable htaccess files
12314 stop working. [Marc Slemko] PR#817
12316 *) Add aplog_error() providing a mechanism to define levels of
12317 verbosity to the server error logging. This addition also provides
12318 the ability to log errors using syslogd. Error logging is configurable
12319 on a per-server basis using the LogLevel directive. Conversion
12320 of log_*() in progress. [Randy Terbush]
12322 *) Further enhance aplog_error() to not log filename, line number, and
12323 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
12325 *) WIN32: Canonicalise filenames under Win32. Short filenames are
12326 converted to long ones. Backslashes are converted to forward
12327 slashes. Case is converted to lower. Parts of URLs that do not
12328 correspond to files are left completely alone. [Ben Laurie]
12330 *) PORT: 2 new OSs added to the list of ports:
12331 Encore's UMAX V: Arieh Markel <amarkel encore.com>
12332 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
12334 *) Add the server version (SERVER_VERSION macro) to the "server
12335 configured and running" entry in the error_log. Also build an
12336 object file at link-time that contains the current time
12337 (SERVER_BUILT global const char[]), and include that in the
12338 message. [Ken Coar]
12340 *) Set r->headers_out when sending responses from the proxy.
12341 This fixes things such as the logging of headers sent from
12342 the proxy. [Marc Slemko] PR#659
12344 *) support/httpd_monitor is no longer distributed because the
12345 scoreboard should not be file based if at all possible. Use
12346 mod_status to see current server snapshot.
12348 *) (set_file_slot): New function, allowing auth directives to be
12349 independent of the server root, so the server documents can be
12350 moved to a different directory or machine more easily.
12351 [David J. MacKenzie]
12353 *) If no TransferLog is given explicitly, decline
12354 to log. This supports coexistence with other logging modules,
12355 such as the custom one that UUNET uses. [David J. MacKenzie]
12357 *) Check for titles in server-parsed HTML files.
12358 Ignore leading newlines and returns in titles. The old behavior
12359 of replacing a newline after <title> with a space causes the
12360 title to be misaligned in the listing. [David J. MacKenzie]
12362 *) Change mod_cern_meta to be configurable on a per-directory basis.
12363 [David J. MacKenzie]
12365 *) Add 'Include' directive to allow inclusion of configuration
12366 files within configuration files. [Randy Terbush]
12368 *) Proxy errors on connect() are logged to the error_log (nothing
12369 new); now they include the IP address and port that failed
12370 (*that's* new). [Ken Coar, Marc Slemko] PR#352
12372 *) Various architectures now define USE_MMAP_FILES which causes
12373 the server to use mmap() for static files. There are two
12374 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
12375 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
12376 number of bytes written in one cycle from a single mmap()d object,
12377 default 32768). [Dean Gaudet]
12379 *) API: Added post_read_request API phase which is run right after reading
12380 the request from a client, or right after an internal redirect. It is
12381 useful for modules setting environment variables that depend only on
12382 the headers/contents of the request. It does not run during subrequests
12383 because subrequests inherit pretty much everything from the main
12384 request. [Dean Gaudet]
12386 *) Added mod_unique_id which is used to generate a unique identifier for
12387 each hit, available in the environment variable UNIQUE_ID.
12390 *) init_modules is now called after the error logs have been opened. This
12391 allows modules to emit information messages into the error logs.
12394 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
12395 information for case where proxy module is not available. [Marc Slemko]
12397 *) PORT: Apache has need for mutexes to serialize its children around
12398 accept. In prior versions either fcntl file locking or flock file
12399 locking were used. The method is chosen by the definition of
12400 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
12401 and FLOCK for flock(). New options have been added:
12402 - SYSVSEM to use System V style semaphores
12403 - PTHREAD to use POSIX threads (appears to work on Solaris only)
12404 - USLOCK to use IRIX uslock
12405 Based on timing various techniques, the following changes were made
12407 - Linux 2.x uses flock instead of fcntl
12408 - Solaris 2.x uses pthreads
12409 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
12410 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
12411 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
12412 Martijn Koster <m.koster pobox.com>]
12414 *) PORT: The semantics of accept/select make it very desirable to use
12415 mutexes to serialize accept when multiple Listens are in use. But
12416 in the case where only a single socket is open it is sometimes
12417 redundant to serialize accept(). Not all unixes do a good job with
12418 potentially dozens of children blocked on accept() on the same
12419 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
12420 the server will avoid serialization when listening on only one socket,
12421 and use serialization when listening on multiple sockets.
12422 [Dean Gaudet] PR#467
12424 *) Configure changes: TestLib replaced by TestCompile, which has
12425 some additional capability (such as doing a sanity check of
12426 the compiler and flags selected); the version of Solaris is now
12427 available via the #define value of SOLARIS2; IRIX n32bit libs
12428 now supported and selectable by new Configuration Rule: IRIXN32;
12429 We no longer default to -O2 optimization. [Jim Jagielski]
12431 *) Updated Configure: Configuration now uses AddModule to specify
12432 module source or binary file location, relative to src directory.
12433 Modules can be dropped into modules/extra, or in their own
12434 directory, and modules can come with a Makefile or Configure can
12435 create one. Modules can add compiler or library information to
12436 generated Makefiles. [Paul Sutton]
12438 *) Source core re-organisation: distributed modules are now in
12439 modules/standard. All other source code is in main. OS-specific
12440 code is in os/{unix,emx,win32} directories. [Paul Sutton]
12442 *) mod_browser has been removed, since it's replaced by mod_setenvif.
12445 *) Fix another long-standing bug in sub_req_lookup_file where it would
12446 happily skip past access checks on subdirectories looked up with
12447 relative paths. (It's used by mod_dir, mod_negotiation,
12448 and mod_include.) [Dean Gaudet]
12450 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
12451 N is the number of <Directory> sections, and M is the number of
12452 components in the filename of an object.
12454 To achieve this optimization the following config changes were made:
12455 - Wildcards (* and ?, not the regex forms) in <Directory>s,
12456 <Files>s, and <Location>s now treat a slash as a special
12457 character. For example "/home/*/public_html" previously would
12458 match "/home/a/andrew/public_html", now it only matches things
12459 like "/home/bob/public_html". This mimics /bin/sh behaviour.
12460 - It's possible now to use [] wildcarding in <Directory>, <Files>
12462 - Regex <Directory>s are applied after all non-regex <Directory>s.
12466 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
12467 and corrupted paths. [Dean Gaudet]
12469 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
12470 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
12471 be accessed now via backreferences $1..$9 in RewriteConds test-against
12472 strings in addition to RewriteRules subst string. Second the grouped
12473 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
12474 via backreferences %1..%9 both in following RewriteCond test-against
12475 strings and RewriteRules subst string. This provides maximum flexibility
12476 through the use of backreferences.
12477 Additionally the rewriting engine was cleaned up by putting common
12478 code to the new expand_backrefs_inbuffer() function.
12479 [Ralf S. Engelschall]
12481 *) When merging the main server's <Directory> and <Location> sections into
12482 a vhost, put the main server's first and the vhost's second. Otherwise
12483 the vhost can't override the main server. [Dean Gaudet] PR#717
12485 *) The <Directory> code would merge and re-merge the same section after
12486 a match was found, possibly causing problems with some modules.
12489 *) ip-based vhosts are stored and queried using a hashing function, which
12490 has been shown to improve performance on servers with many ip-vhosts.
12491 Some other changes had to be made to accommodate this:
12492 - the * address for vhosts now behaves like _default_
12493 - the matching process now is:
12494 - match an ip-vhost directly via hash (possibly matches main
12496 - if that fails, just pretend it matched the main server
12497 - if so far only the main server has been matched, perform
12498 name-based lookups (ServerName, ServerAlias, ServerPath)
12499 *only on name-based vhosts*
12500 - if they fail, look for _default_ vhosts
12501 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
12503 *) dbmmanage overhaul:
12504 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
12505 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
12506 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
12507 - provide better seed for rand
12508 - prompt for password as per getpass(3) (turn off echo, read from
12510 - use "newstyle" crypt based on $Config{osname} ($^O)
12511 - will not add a user if already in database, use new `update' command
12513 - added `check' command to check a users' password
12514 - added `import' command to convert existing password text-files or
12515 dbm files exported with `view'
12516 - more descriptive usage, general cleanup, 'use strict' clean, etc.
12519 *) Added psocket() which is a pool form of socket(), various places within
12520 the proxy weren't properly blocking alarms while registering the cleanup
12521 for its sockets. bclose() now uses pclose() and pclosesocket(). There
12522 was a bug where the client socket was being close()d twice due a still
12523 registered cleanup. [Dean Gaudet]
12525 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
12528 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
12529 [Jason Venner <jason idiom.com>] PR#667
12531 *) Enable ``=""'' for RewriteCond directives to match against
12532 the empty string. This is the preferred way instead of ``^$''.
12533 [Ralf S. Engelschall]
12535 *) Fixed an infinite loop in mod_imap for references above the server root
12536 [Dean Gaudet] PR#748
12538 *) mod_proxy now has a ReceiveBufferSize directive, similar to
12539 SendBufferSize, so that the TCP window can be set appropriately
12540 for LFNs. [Phillip A. Prindeville]
12542 *) mod_browser has been replaced by the more general mod_setenvif
12543 (courtesy of Paul Sutton). BrowserMatch* directives are still
12544 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
12545 UnSetEnvIfZero directives. [Ken Coar]
12547 *) "HostnameLookups double" forces double-reverse DNS to succeed in
12548 order for remote_host to be set (for logging, or for the env var
12549 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
12552 *) mod_access overhaul:
12553 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
12554 and cidr syntax (i.e. 10.1.0.0/16). PR#762
12555 - Critical path was sped up by pre-computing a few things at config time.
12556 - The undocumented syntax "allow user-agents" was removed,
12557 the replacement is "allow from env=foobar" combined with mod_browser.
12558 - When used with hostnames it now forces a double-reverse lookup
12559 no matter what the directory settings are. This double-reverse
12560 doesn't affect any of the other routines that use the remote
12561 hostname. In particular it's still passed to CGIs and the log
12562 without the double-reverse check. Related PR#860.
12565 *) When a large bwrite() occurs (larger than the internal buffer size),
12566 while there is already something in the buffer, apache will combine
12567 the large write and the buffer into a single writev(). (This is
12568 in anticipation of using mmap() for reading files.)
12571 *) In obscure cases where a partial socket write occurred while chunking,
12572 Apache would omit the chunk header/footer on the next block. Cleaned
12573 up other bugs/inconsistencies in error conditions in buff.c. Fixed
12574 a bug where a long pause in DNS lookups could cause the last packet
12575 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
12577 *) API: Added child_exit function to module structure. This is called
12578 once per "heavy-weight process" just before a server child exit()'s
12579 e.g. when max_requests_per_child is reached, etc.
12580 [Doug MacEachern, Dean Gaudet]
12582 *) mod_include cleanup showed that handle_else was being used to handle
12583 endif. It didn't cause problems, but it was cleaned up too.
12586 *) mod_cern_meta would attempt to find meta files for the directory itself
12587 in some cases, but not in others. It now avoids it in all cases.
12590 *) mod_mime_magic would core dump if there was a decompression error.
12591 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
12593 *) PORT: some variants of DGUX require -lsocket -lnsl
12594 [Alexander L Jones <alex systems-options.co.uk>] PR#732
12596 *) mod_autoindex now allows sorting of FancyIndexed directory listings
12597 by the various fields (name, size, et cetera), either in ascending
12598 or descending order. Just click on the column header. [Ken Coar]
12600 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
12601 CPUs like the Alpha. Apache still stores ints in pointers, but that's
12602 the relatively safe direction. [Dean Gaudet] PR#344
12604 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
12605 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
12607 *) child_main avoids an unneeded call to select() when there is only one
12608 listening socket. [Dean Gaudet]
12610 *) In the event that the server is starved for idle servers it will
12611 spawn 1, then 2, then 4, ..., then 32 servers each second,
12612 doubling each second. It'll also give a warning in the errorlog
12613 since the most common reason for this is a poor StartServers
12614 setting. The define MAX_SPAWN_RATE can be used to raise/lower
12615 the maximum. [Dean Gaudet]
12617 *) Apache now provides an effectively unbuffered connection for
12618 CGI scripts. This means that data will be sent to the client
12619 as soon as the CGI pauses or stops output; previously, Apache would
12620 buffer the output up to a fixed buffer size before sending, which
12621 could result in the user viewing an empty page until the CGI finished
12622 or output a complete buffer. It is no longer necessary to use an
12623 "nph-" CGI to get unbuffered output. Given that most CGIs are written
12624 in a language that by default does buffering (e.g. perl) this
12625 shouldn't have a detrimental effect on performance.
12627 "nph-" CGIs, which formerly provided a direct socket to the client
12628 without any server post-processing, were not fully compatible with
12629 HTTP/1.1 or SSL support. As such they would have had to implement
12630 the transport details, such as encryption or chunking, in order
12631 to work properly in certain situations. Now, the only difference
12632 between nph and non-nph scripts is "non-parsed headers".
12633 [Dean Gaudet, Sameer Parekh, Roy Fielding]
12635 *) If a BUFF is switched from buffered to unbuffered reading the first
12636 bread() will return whatever remained in the buffer prior to the
12637 switch. [Dean Gaudet]
12639 Changes with Apache 1.3a1
12641 *) Added another Configure helper script: TestLib. It determines
12642 if a specified library exists. [Jim Jagielski]
12644 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
12645 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
12648 *) PORT: Some architectures use size_t for various lengths in network
12649 functions such as accept(), and getsockname(). The definition
12650 NET_SIZE_T is used to control this. [Dean Gaudet]
12652 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
12653 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
12654 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
12656 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
12657 [Igor N Kovalenko <infoh mail.wplus.net>]
12659 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
12660 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
12661 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
12662 [Dean Gaudet] related PR#875
12664 *) API: Correct child_init() slot declaration from int to void, to
12665 match the init() declaration. Update mod_example to use the new
12668 *) added transport handle slot (t_handle) to the BUFF structure
12671 *) get_client_block() returns wrong length if policy is
12672 REQUEST_CHUNKED_DECHUNK.
12673 [Kenichi Hori <ken d2.bs1.fc.nec.co.jp>] PR#815
12675 *) Support the image map format of FrontPage. For example:

12679 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
12680 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
12682 *) AddModuleInfo directive for mod_info which allows you to annotate
12683 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
12685 *) Added NoProxy directive to avoid using ProxyRemote for selected
12686 addresses. Added ProxyDomain directive to cause unqualified
12687 names to be qualified by redirection.
12688 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
12690 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
12691 header to the remote host in the proxy. [Sameer Parekh and
12694 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
12695 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
12696 URLs, fixed rewritelog(), fixed forced response code handling on
12697 redirects from within .htaccess files, disabled pipe locking under
12698 braindead SunOS 4.1.x, allow env variables to be set even on rules with
12699 no substitution, bugfixed situations where HostnameLookups is off, made
12700 mod_rewrite more thread-safe for NT port and fixed problem when creating
12701 an empty query string via "xxx?".
12702 This update also removes the copyright of Ralf S. Engelschall,
12703 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
12704 exclusively copyrighted by the Apache Group now. This happened because
12705 the author now has gifted mod_rewrite exclusively to the Apache Group and
12706 no longer maintains an external version.
12707 [Ralf S. Engelschall]
12709 *) API: Added child_init function to module structure. This is called
12710 once per "heavy-weight process" before any requests are handled.
12711 See http_config.h for more details. [Dean Gaudet]
12713 *) Anonymous_LogEmail was logging on each subrequest.
12714 [Dean Gaudet] PR#421, 868
12716 *) API: Added is_initial_req() which tests if the request being
12717 processed is the initial request, or a subrequest.
12720 *) Extended SSI (mod_include) now handles additional relops for
12721 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
12723 *) Configure fixed to correctly propagate user-selected options and
12724 settings (such as CC and OPTIM) to Makefiles other than
12725 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
12727 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
12728 directory indices to start with the contents of the HeaderName file
12729 if there is one. If there isn't one, the behaviour is unchanged.
12730 [Ken Coar, Roy Fielding, Andrey A. Chernov]
12732 *) WIN32: Modules can now be dynamically loaded DLLs using the
12733 LoadModule/LoadFile directives. Note that module DLLs must be
12734 compiled with the multithreaded DLL version of the runtime library.
12735 [Alexei Kosut and Ben Laurie]
12737 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
12738 This allows the admin to completely remove automatic indexing
12739 from the server, while still supporting the basic functions of
12740 trailing-slash redirects and DirectoryIndex files. Note that if
12741 you're carrying over an old Configuration file and you use directory
12742 indexing then you'll want to add:
12744 Module autoindex_module mod_autoindex.o
12746 before mod_dir in your Configuration. [Dean Gaudet]
12748 *) popendir/pclosedir created to properly protect directory scanning.
12749 [Dean Gaudet] PR#525
12751 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
12752 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
12753 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
12756 *) The AccessFileName directive can now take more than one filename.
12757 ["Lou D. Langholtz" <ldl usi.utah.edu>]
12759 *) The new mod_mime_magic can be used to "magically" determine the type
12760 of a file if the extension is unknown. Based on the unix file(1)
12761 command. [Ian Kluft <ikluft cisco.com>]
12763 *) We now determine and display the time spent processing a
12764 request if desired. [Jim Jagielski]
12766 *) mod_status: PID field of "dead" child slots no longer displays
12767 main httpd process's PID. [Jim Jagielski]
12769 *) Makefile.nt added - to build all the bits from the command line:
12770 nmake -f Makefile.nt
12771 Doesn't yet work properly. [Ben Laurie]
12773 *) Default text of 404 error is now "Not Found" rather than the
12774 potentially misleading "File Not Found". [Ken Coar]
12776 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
12777 for the net if we require people that actually need this data to
12778 enable it. [Linus Torvalds]
12780 *) directory_walk() is an expensive function, keep a little more state to
12781 avoid needless string counting. Add two new functions make_dirstr_parent
12782 and make_dirstr_prefix which replace all existing uses of make_dirstr.
12783 The new functions are a little less general than make_dirstr, but
12784 work more efficiently (less memory, less string counting).
12787 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
12788 to LDFLAGS) to avoid complications with lex rules in make files.
12789 [Dean Gaudet] PR#372
12791 *) run_method optimized to avoid needless scanning over NULLs in the
12792 module list. [Dean Gaudet]
12794 *) Revamp of (unix) scoreboard management code such that it avoids
12795 unnecessary traversals of the scoreboard on each hit. This is
12796 particularly important for high volume sites with a large
12797 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
12798 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
12799 httpd.h. [Dean Gaudet]
12801 *) In configurations using multiple Listen statements it was possible for
12802 busy sockets to starve other sockets of service. [Dean Gaudet]
12804 *) Added hook so standalone_main can be replaced at compile time
12805 (define STANDALONE_MAIN)
12808 *) Lowest-level read/write functions in buff.c will be replaced with
12809 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
12810 compile time. The default sfio discipline will behave as apache
12811 would without sfio compiled in.
12814 *) Enhance UserDir directive (mod_userdir) to accept a list of
12815 usernames for the 'disable' keyword, and add 'enable user...' to
12816 selectively *en*able userdirs if they're globally disabled.
12819 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
12820 will work with Netscape dbm files. (dbmmanage will probably not
12821 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
12823 *) Add a ListenBacklog directive to control the backlog parameter
12824 passed to listen(). Also change the default to 511 from 512.
12827 *) API: A new handler response DONE which informs apache that the
12828 request has been handled and it can finish off quickly, similar to
12829 how it handles errors. [Rob Hartill]
12831 *) Turn off chunked encoding after sending terminating chunk/footer
12832 so that we can't do it twice by accident. [Roy Fielding]
12834 *) mod_expire also issues Cache-Control: max-age headers.
12837 *) API: Added kill_only_once option for free_proc_chain so that it won't
12838 aggressively try to kill off specific children. For fastcgi.
12839 [Stanley Gambarin <gambarin OpenMarket.com>]
12841 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
12843 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
12844 When used together, these cause mod_dir to emit HEIGHT and WIDTH
12845 attributes in the FancyIndexing IMG tags. [Ken Coar]
12847 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
12849 *) PORT: Added Windows NT support
12850 [Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
12852 Changes with Apache 1.2.6

13154 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
13155 which keeps all non-FILE * descriptors above 255. On all systems
13156 this should make supporting large numbers of vhosts with many open

13294 the CGI script filename. The environment variable FILEPATH_INFO has
13295 been removed, and instead we supply the original REQUEST_URI to any
13296 script that wants to be Apache-specific and needs the real URI path.
13297 This solves a problem with existing scripts that use extra path info
13298 in the ScriptAlias directive to pass options to the CGI script.

13365 while obtaining the /~user and save the username in a separate data
13366 area so that it won't be overwritten by the call to getgrgid(), and
13367 fix some misuse of the pool string allocation functions. Also fixes
13368 a general problem with parsing URL query info into args for CGI scripts.
13369 [Roy Fielding] PR#339, 367, 354, 453
13371 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
13373 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
13375 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
13376 AuthDBAuthoritative. [Marc Slemko] PR#420
13378 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
13380 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
13381 object that can't be PUT, or FOOBAR for some method FOOBAR that
13382 apache doesn't know about at all). Log 404s that occur in mod_include.
13383 [Paul Sutton, John Van Essen]
13385 *) If a soft timeout (or lingerout) occurs while trying to flush a
13386 buffer or write inside buff.c or fread'ing from a CGI's output,
13387 then the timeout would be ignored. [Roy Fielding] PR#373
13389 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
13390 parsing of headers. If the terminating empty-line CRLF occurs starting
13391 at the 256th or 257th byte of output, then Navigator will think a normal
13392 image is invalid. We are guessing that this is because their initial
13393 read of a new request uses a 256 byte buffer. We check the bytes written
13394 so far and, if we are about to tickle the bug, we instead insert a
13395 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
13397 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
13398 of an external redirection. [Roy Fielding and Paul Sutton]
13400 *) Configure would create a broken Makefile if the configuration file
13401 contained a commented-out Rule. [Roy Fielding]
13403 *) Promote per_dir_config and subprocess_env from the subrequest to the
13404 main request in mod_negotiation. In particular this fixes a bug
13405 where <Files> sections wouldn't properly apply to negotiated content.
13408 *) Fix a potential deadlock in mod_cgi script_err handling.
13409 [Ralf S. Engelschall]
13411 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
13412 [Mitchell Blank Jr]
13414 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
13415 .htaccess files because the RewriteBase was not replaced correctly.
13416 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
13417 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
13419 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
13420 1.x the settings are those of pre-1.2b8. For 2.x we include
13421 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
13422 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
13423 [Dean Gaudet] PR#336, PR#340
13425 *) Redirect did not preserve ?query_strings when present in the client's
13426 request. [Dean Gaudet]
13428 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
13430 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
13432 *) Add UnixWare compile/install instructions. [Chuck Murcko]
13434 *) Add mod_example (illustration of API techniques). [Ken Coar]
13436 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
13438 *) Improve handling of directories when filenames have spaces in them.
13441 *) For hosts with multiple IP addresses, try all additional addresses if
13442 necessary to get a connect. Fail only if hostent address list is
13443 exhausted. [Chuck Murcko]
13445 *) More signed/unsigned port fixes. [Dean Gaudet]
13447 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
13450 Changes with Apache 1.2b8
13452 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
13453 to it. [Marc Slemko]
13455 *) The addition of <Location> and <File> directives made the
13456 sub_req_lookup_simple() function bogus, so we now handle
13457 the special cases directly. [Dean Gaudet]
13459 *) We now try to log where the server is dumping core when a fatal
13460 signal is received. [Ken Coar]
13462 *) Improved lingering_close by adding a special timeout, removing the
13463 spurious log messages, removing the nonblocking settings (they
13464 are not needed with the better timeout), and adding commentary
13465 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
13466 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
13468 *) Send error messages about setsockopt failures to the server error
13469 log instead of stderr. [Roy Fielding]
13471 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
13473 *) Stopgap solution for CGI 3-second delay with server-side includes: if
13474 processing a subrequest, allocate memory from r->main->pool instead
13475 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
13476 in the middle of an SSI request. [Dean Gaudet] PR #122
13478 *) Fixed status of response when POST is received for a nonexistent URL
13479 (was sending 405, now 404) and when any method is sent with a
13480 full-URI that doesn't match the server and the server is not acting
13481 as a proxy (was sending 501, now 403). [Roy Fielding]
13483 *) Host port changed to unsigned short. [Ken Coar] PR #276
13485 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
13487 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
13489 *) Report extra info from errno with many errors that cause httpd to exit.
13490 spawn_child, popenf, and pclosef now have valid errno returns in the
13491 event of an error. Correct problems where errno was stomped on
13492 before being reported. [Dean Gaudet]
13494 *) In the proxy, if the cache filesystem was full, garbage_coll() was
13495 never called, and thus the filesystem would remain full indefinitely.
13496 We now also remove incomplete cache files left if the origin server
13497 didn't send a Content-Length header and either the client has aborted
13498 transfer or bwrite() to client has failed. [Petr Lampa]
13500 *) Fixed the handling of module and script-added header fields.
13501 Improved the interface for sending header fields and reduced
13502 the duplication of code between sending okay responses and errors.
13503 We now always send both headers_out and err_headers_out, and
13504 ensure that the server-reserved fields are not being overridden,
13505 while not overriding those that are not reserved. [Roy Fielding]
13507 *) Moved transparent content negotiation fields to err_headers_out
13508 to reflect above changes. [Petr Lampa]
13510 *) Fixed the determination of whether or not we should make the
13511 connection persistent for all of the cases where some other part
13512 of the server has already indicated that we should not. Also
13513 improved the ordering of the test so that chunked encoding will
13514 be set whenever it is desired instead of only when KeepAlive
13515 is enabled. Added persistent connection capability for most error
13516 responses (those that do not indicate a bad input stream) when
13517 accessed by an HTTP/1.1 client. [Roy Fielding]
13519 *) Added missing timeouts for sending header fields, error responses,
13520 and the last chunk of chunked encoding, each of which could have
13521 resulted in a process being stuck in write forever. Using soft_timeout
13522 requires that the sender check for an aborted connection rather than
13523 continuing after an EINTR. Timeouts that used to be initiated before
13524 send_http_header (and never killed) are now initiated only within or
13525 around the routines that actually do the sending, and not allowed to
13526 propagate above the caller. [Roy Fielding]
13528 *) mod_auth_anon required an @ or a . in the email address, not both.
13531 *) per_dir_defaults weren't set correctly until directory_walk for
13532 name-based vhosts. This fixes an obscure bug with the wrong config
13533 info being used for vhosts that share the same ip as the server.
13536 *) Improved generation of modules/Makefile to be more generic for
13537 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
13539 *) Generate makefile dependency for Configuration based on the actual
13540 name given when running the Configure process. [Dean Gaudet]
13542 *) Fixed problem with vhost error log not being set prior to
13543 initializing virtual hosts. [Dean Gaudet]
13545 *) Fixed infinite loop when a trailing slash is included after a type map
13546 file URL (extra path info). [Petr Lampa]
13548 *) Fixed server status updating of per-connection counters. [Roy Fielding]
13550 *) Add documentation for DNS issues (reliability and security), and try
13551 to explain the virtual host matching process. [Dean Gaudet]
13553 *) Try to continue gracefully by disabling the vhost if a DNS lookup
13554 fails while parsing the configuration file. [Dean Gaudet]
13556 *) Improved calls to setsockopt. [Roy Fielding]
13558 *) Negotiation changes: Don't output empty content-type in variant list;
13559 Output charset in variant list; Return sooner from handle_multi() if
13560 no variants found; Add handling of '*' wildcard in Accept-Charset.
13561 [Petr Lampa and Paul Sutton]
13563 *) Fixed overlaying of request/sub-request notes and headers in
13564 mod_negotiation. [Dean Gaudet]
13566 *) If two variants' charset quality are equal and one is the default
13567 charset (iso-8859-1), then prefer the variant that was specifically
13568 listed in Accept-Charset instead of the default. [Petr Lampa]
13570 *) Memory allocation problem in push_array() -- it would corrupt memory
13571 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
13573 *) invoke_handler() doesn't handle mime arguments in content-type
13574 [Petr Lampa] PR#160
13576 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
13579 *) Fixed problem with ErrorDocument not working for virtual hosts
13580 due to one of the performance changes in 1.2b7. [Dean Gaudet]
13582 *) Log an error message if we get a request header that is too long,
13583 since it may indicate a buffer overflow attack. [Marc Slemko]
13585 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
13586 not reject URLs without a double-slash, as per RFC2068 section 3.2.
13587 [Ken Coar] PR #146, #187
13589 *) Added table entry placeholder for new header_parser callback
13590 in all of the distributed modules. [Ken Coar] PR #191
13592 *) Allow for cgi files without the .EXE extension on them under OS/2.
13593 [Garey Smiley] PR #59
13595 *) Fixed error message when resource is not found and URL contains
13596 path info. [Petr Lampa and Dean Gaudet] PR #40
13598 *) Fixed user and server confusion over what should be a virtual host
13599 and what is the main server, resulting in access to something
13600 other than the name defined in the virtualhost directive (but
13601 with the same IP address) failing. [Dean Gaudet]
13603 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
13604 AIX; improves the redirection stuff to enable the users to generally
13605 redirect to http, https, gopher and ftp; added TIME variable for
13606 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
13607 special patterns >STRING, <STRING and =STRING to RewriteCond, which
13608 can be used in conjunction with %{TIME} or other variables to create
13609 time-dependent rewriting rules. [Ralf S. Engelschall]
13611 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
13612 Module authors may need to adjust their code for proper cleanup to take
13613 place (that is, call note_cleanups_for_fd()). This change fixes problems
13614 with file descriptors being erroneously closed when the proxy module was
13615 in use. [Ben Laurie]
13617 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
13618 initgroups() to hose the group information needed for later
13619 comparisons. [Randy Terbush]
13621 *) Remove unnecessary call to va_end() in create_argv() which
13622 caused a SEGV on some systems.
13624 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
13627 *) Clear memory allocated for listeners. [Randy Terbush]
13629 *) Improved handling of IP address as a virtualhost address and
13630 introduced "_default_" as a synonym for the default vhost config.

13639 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
13640 - replace protocol response numbers with symbols
13641 - save variant-list into main request notes
13642 - free allocated memory from subrequests
13643 - merge notes, headers_out and err_headers_out
13645 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
13646 "HTTP/#.# ###*" to be more lenient about what we accept.
13649 *) more proxy FTP bug fixes:
13650 - Changed send_dir() to remove user/passwd from displayed URL.
13651 - Changed login error messages to be more descriptive.
13652 - remove setting of SO_DEBUG socket option
13653 - Make ftp_getrc() more lenient about multiline responses,
13654 specifically, 230 responses which don't have continuation 230-
13655 on each line). These seem to be all NT FTP servers, and while
13656 perhaps questionable, they appear to be legal by RFC 959.
13657 - Add missing kill_timeout() after transfer to user completes.
13660 *) Fixed problem where a busy server could hang when restarting
13661 after being sent a SIGHUP due to child processes not exiting.
13664 *) Modify mod_include escaping so a '\' only signifies an escaped
13665 character if the next character is one that needs
13666 escaping. [Ben Laurie]
13668 *) Eliminated possible infinite loop in mod_imap when relative URLs are
13669 used with a 'base' directive that does not have a '/' in it.
13670 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
13672 *) Reduced the default timeout from 1200 seconds to 300, and the
13673 one in the sample configfile from 400 to 300. [Marc Slemko]
13675 *) Stop vbprintf from crashing if given a NULL string pointer;
13676 print (null) instead. [Ken Coar]
13678 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
13679 [Marc Slemko and Roy Fielding]
13681 *) Fixed problem with mod_cgi-generated internal redirects trying to
13682 read the request message-body twice. [Archie Cobbs and Roy Fielding]
13684 *) Reduced timeout on lingering close, removed possibility of a blocked
13685 read causing the child to hang, and stopped logging of errors if
13686 the socket is not connected (reset by client). [Roy Fielding]
13688 *) Rearranged main child loop to remove duplication of code in
13689 select/accept and keep-alive requests, fixed several bugs regarding
13690 checking scoreboard_image for exit indication and failure to
13691 account for all success conditions and trap all error conditions,
13692 prevented multiple flushes before closing the socket; close the entire
13693 socket buffer instead of just one descriptor, prevent logging of
13694 EPROTO and ECONNABORTED on platforms where supported, and generally
13695 improved readability. [Roy Fielding]
13697 *) Extensive performance improvements. Cleaned up inefficient use of
13698 auto initializers, multiple is_matchexp calls on a static string,
13699 and excessive merging of response_code_strings. [Dean Gaudet]
13701 *) Added double-buffering to mod_include to improve performance on
13702 server-side includes. [Marc Slemko]
13704 *) Several fixes for suexec wrapper. [Randy Terbush]
13705 - Make wrapper work for files on NFS filesystem.
13706 - Fix portability problem of MAXPATHLEN.
13707 - Fix array overrun problem in clean_env().
13708 - Fix allocation of PATH environment variable
13710 *) Removed extraneous blank line is description of mod_status chars.
13713 *) Logging of errors from the call_exec routine simply went nowhere,
13714 since the logfile fd has been closed, so now we send them to stderr.
13715 [Harald T. Alvestrand]
13717 *) Fixed core dump when DocumentRoot is a CGI.
13718 [Ben Laurie, reported by <geddis tesserae.com>]
13720 *) Fixed potential file descriptor leak in mod_asis; updated it and
13721 http_core to use pfopen/pfclose instead of fopen/fclose.
13722 [Randy Terbush and Roy Fielding]
13724 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
13725 as the DEC Alpha which is 64-bit but uses 32-bit ints.
13726 [Dean Gaudet and Ken Coar]
13728 *) Return a 302 response code to the client when sending a redirect
13729 due to a missing trailing '/' on a directory instead of a 301; now
13730 it is cacheable. [Markus Gyger]
13732 *) Fix condition where, if a bad directive occurs in .htaccess, and
13733 sub_request() goes first to this directory, then log_reason() will
13734 SIGSEGV because it doesn't have initialized r->per_dir_config.
13735 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
13737 *) Fix handling of lang_index in is_variant_better(). This was
13738 causing problems which resulted in the server sending the
13739 wrong language document in some cases. [Petr Lampa]
13741 *) Remove free() from clean_env() in suexec wrapper. This was nuking
13742 the clean environment on some systems.
13744 *) Tweak byteserving code (e.g. serving PDF files) to work around
13745 bugs in Netscape Navigator and Microsoft Internet Explorer.
13746 Emit Content-Length header when sending multipart/byteranges.
13749 *) Port to HI-UX/WE2. [Nick Maclaren]
13751 *) Port to HP MPE operating system for HP 3000 machines
13752 [Mark Bixby <markb cccd.edu>]
13754 *) Fixed bug which caused a segmentation fault if only one argument
13755 given to RLimit* directives. [Ed Korthof]
13757 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
13759 *) Improved buffered output to the client by delaying the flush decision
13760 until the BUFF code is actually about to read the next request.
13761 This fixes a problem introduced in 1.2b5 with clients that send
13762 an extra CRLF after a POST request. Also improved chunked output
13763 performance by combining writes using writev() and removing as
13764 many bflush() calls as possible. NOTE: Platforms without writev()
13765 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
13766 or Configure, unless we have already done so. [Dean Gaudet]
13768 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
13770 *) Fixed mod_info output corruption bug introduced by buffer overflow
13771 fixes. [Dean Gaudet]
13773 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
13774 for the special case of a 304 response. [Paul Sutton]
13776 *) Improved handling of TRACE method by bypassing normal method handling
13777 and header parsing routines; fixed Allow response to always allow TRACE.
13780 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
13782 *) Cleaned-up some of the generated HTML. [Ken Coar]
13784 Changes with Apache 1.2b6
13786 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
13788 *) Fix typo introduced in fix for potential infinite loop around
13789 accept() in child_main(). This change caused the rev to 1.2b6.
13790 1.2b5 was never a public beta.
13792 Changes with Apache 1.2b5
13794 *) Change KeepAlive semantics (On|Off instead of a number), add
13795 MaxKeepAliveRequests directive. [Alexei Kosut]
13797 *) Various NeXT compilation patches, as well as a change in
13798 regex/regcomp.c since that file also used a NEXT define.
13801 *) Allow * to terminate the end of a directory match in mod_dir.
13802 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
13804 *) Don't call can_exec() if suexec_enabled. Calling this requires
13805 scripts executed by the suexec wrapper to be world executable, which
13806 defeats one of the advantages of running the wrapper. [Randy Terbush]
13808 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
13811 *) Migration from sprintf() to snprintf() to avoid buffer
13812 overflows. [Marc Slemko]
13814 *) Provide portable snprintf() implementation (ap_snprintf)
13815 as well as *cvt family. [Jim Jagielski]
13817 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
13820 *) Remove mod_fastcgi.c from the distribution. This module appears
13821 to be maintained more through the Open Market channels and should
13822 continue to be easily available at http://www.fastcgi.com/
13824 *) Fixed bug in modules/Makefile that wouldn't allow building in more
13825 than one subdirectory (or cleaning, either). [Jeremy Laidman]
13827 *) mod_info assumed that the config files were relative to ServerRoot.
13830 *) CGI scripts called as an error document resulting from failed
13831 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
13833 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
13836 *) Properly check errno to prevent display of a directory index
13837 when server receives a long enough URL to confuse stat().
13840 *) Several security enhancements to suexec wrapper. It is _highly_
13841 recommended that previously installed versions of the wrapper
13842 be replaced with this version. [Randy Terbush, Jason Dour]
13844 - ~user execution now properly restricted to ~user's home
13845 directory and below.
13846 - execution restricted to UID/GID > 100
13847 - restrict passed environment to known variables
13848 - call setgid() before initgroups() (portability fix)
13849 - remove use of setenv() (portability fix)
13851 *) Add HTTP/1.0 response forcing. [Ben Laurie]
13853 *) Add access control via environment variables. [Ben Laurie]
13855 *) Add rflush() function. [Alexei Kosut]
13857 *) remove duplicate pcalloc() call in new_connection().
13859 *) Fix incorrect comparison which could allow number of children =
13860 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
13861 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
13863 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
13864 AIX PS/2, CONVEXOS. [Jim Jagielski]
13866 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
13867 It's more portable. [Martin Kraemer]
13869 *) Replace references to make in Makefile.tmpl with $(MAKE).
13872 *) Add ProxyBlock directive w/IP address caching. Add IP address
13873 caching to NoCache directive as well. ProxyBlock works with all
13874 handlers; NoCache now also works with FTP for anonymous logins.
13875 Still more code cleanup. [Chuck Murcko]
13877 *) Add "header parse" API hook [Ben Laurie]
13879 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
13881 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
13883 *) Correctly allow access and auth directives in <Files> sections in
13884 server config files. [Alexei Kosut]
13886 *) Fix bug with ServerPath that could cause certain files to be not
13887 found by the server. [Alexei Kosut]
13889 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
13890 double-quote from text and so that it properly checks for unsupported
13891 status codes using the new index_of_response interface. [Roy Fielding]
13893 *) Multiple fixes to the lingering_close code in order to avoid being
13894 interrupted by a stray timeout, to avoid lingering on a connection
13895 that has already been aborted or never really existed, to ensure that
13896 we stop lingering as soon as any error condition is received, and to
13897 prevent being stuck indefinitely if the read blocks. Also improves
13898 reporting of error conditions. [Marc Slemko and Roy Fielding]
13900 *) Fixed initialization of parameter structure for sigaction.
13901 [<mgyger itr.ch>, Adrian Filipi-Martin]
13903 *) Fixed reinitializing the parameters before each call to accept and
13904 select, and removed potential for infinite loop in accept.
13905 [Roy Fielding, after useful PR from <adrian virginia.edu>]
13907 *) Fixed condition where, if a child fails to fork, the scoreboard would
13908 continue to say SERVER_STARTING forever. Eventually, the main process
13909 would refuse to start new children because count_idle_servers() will
13910 count those SERVER_STARTING entries and will always report that there
13911 are enough idle servers. [Phillip Vandry]
13913 *) Fixed bug in bcwrite regarding failure to account for partial writes.
13914 Avoided calling bflush() when the client is pipelining requests.
13915 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
13917 *) Added description of "." mode in server-status [Jim Jagielski]
13919 Changes with Apache 1.2b4
13921 *) Fix possible race condition in accept_mutex_init() that
13922 could leave a small security hole open allowing files to be
13923 overwritten in cases where the server UID has write permissions.
13926 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
13928 *) Fix portablity problem in util_script where ARG_MAX may not be
13929 defined for some systems.
13931 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
13934 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
13935 style magic #! token for better script portability. [Garey Smiley]
13937 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
13938 execution for ~userdir CGI. [Jason Dour]
13940 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
13942 *) Fix month off by one in suexec wrapper logging.
13944 Changes with Apache 1.2b3:
13946 *) Fix error in mod_cgi which could cause resources not to be properly
13947 freed, or worse. [Dean Gaudet]
13949 *) Fix find_string() NULL pointer dereference. [Howard Fear]
13951 *) Add set_flag_slot() at the request of Dirk and others.
13954 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
13956 *) Add changes to improve the error message given for invalid
13957 ServerName parameters. [Dirk vanGulik]
13959 *) Add "Authoritative" directive for Auth modules that don't
13960 currently have it. This gives admin control to assign authoritative
13961 control to an authentication scheme and allow "fall through" for
13962 those authentication modules that aren't "Authoritative" thereby
13963 allowing multiple authentication mechanisms to be chained.
13966 *) Remove requirement for ResourceConfig/AccessConfig if not using
13967 the three config file layout. [Randy Terbush]
13969 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
13971 *) Changes to suexec wrapper to fix the following problems:
13972 1. symlinked homedirs will kill ~userdirs.
13973 2. initgroups() on Linux 2.0.x clobbers gr->grid.
13974 3. CGI command lines paramters problems
13975 4. pw-pwdir for "docroot check" still the httpd user's pw record.
13976 [Randy Terbush, Jason Dour]
13978 *) Change create_argv() to accept variable arguments. This fixes
13979 a problem where arguments were not getting passed to the CGI via
13980 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
13982 *) Collapse multiple slashes in path URLs to properly apply
13983 handlers defined by <Location>. [Alexei Kosut]
13985 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
13987 *) Improve the accuracy of request duration timings by setting
13988 r->request_time in read_request_line() instead of read_request().
13991 *) Reset timeout while reading via get_client_block() in mod_cgi.c
13992 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
13994 *) Add the ability to pass different Makefile.tmpl files to Configure
13995 using the -make flag. [Rob Hartill]
13997 *) Fix coredump triggered when sending a SIGHUP to the server caused
13998 by an assertion failure, in turn caused by an uninitialised field in a
14002 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
14003 PATH_INFO from previous versions of Apache (in certain situations,
14004 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
14005 [later removed in 1.2b11]
14007 *) Add rwrite() function to API to allow for sending strings of
14008 arbitrary length. [Doug MacEachern]
14010 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
14012 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
14013 NeXT. [Jim Jagielski]
14015 *) Removed recent modification to promote the status code on internal
14016 redirects, since the correct fix was to change the default log format
14017 in mod_log_config so that it outputs the original status. [Rob Hartill]
14019 Changes with Apache 1.2b2:
14021 *) Update set_signals() to use sigaction() for setting handlers.
14022 This appears to fix a re-entrant problem in the seg_fault()
14023 bus_error() handlers. [Randy Terbush]
14025 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
14027 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
14029 *) proxy_http.c bugfixes: [Chuck Murcko]
14030 1) fixes possible NULL pointer reference w/NoCache
14031 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
14032 host would cache nothing if it was in the local domain,
14033 and the local domain was in the NoCache list)
14034 3) Adds Host: header when not available
14035 4) Some code cleanup and clarification
14037 *) mod_include.c bugfixes:
14038 1) Fixed an ommission that caused include variables to not
14039 be parsed in config errmsg directives [Howard Fear]
14040 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
14041 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
14042 4) Allow backslash-escaping to all quoted text
14043 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
14044 5) Pass variable to command line if not set in XSSI's env
14047 *) Fix infinite loop when processing Content-language lines in
14048 type-map files. [Alexei Kosut]
14050 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
14052 *) Fixed problem in set_[user|group] that prevented CGI execution
14053 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
14055 *) Added PORTING information file. [Jim Jagielski]
14057 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
14059 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
14061 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
14062 USE_FCNTL_SERIALIZED_ACCEPT was intended.
14064 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
14065 which caused problems of systems where socket s_addr is >32bits.
14067 *) Added comment to explain (r->chunked = 1) side-effect in
14068 http_protocol.c [Roy Fielding]
14070 *) Replaced use of index() in mod_expires.c with more appropriate
14071 and portable isdigit() test. [Ben Laurie]
14073 *) Updated Configure for ...
14074 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
14075 *-dg-dgux* (bad pattern match)
14076 QNX (DEF_WANTHSREGEX=yes)
14077 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
14079 *-unixware211 (new)
14080 and added some user diagnostic info. [Ben Laurie]
14082 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
14083 for better portability. [Jim Jagielski]
14085 *) Updated helpers/GuessOS for ...
14086 SCO 5 (recognize minor releases)
14087 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
14088 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
14089 IRIX64 (-sgi-irix64)
14090 ULTRIX (-unknown-ultrix)
14091 SINIX (-whatever-sysv4)
14092 NCR Unix (-ncr-sysv4)
14093 and fixed something in helpers/PrintPath [Ben Laurie]
14095 Changes with Apache 1.2b1
14097 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
14099 Changes with Apache 1.1.1
14101 *) Fixed bug where Cookie module would make two entries in the
14102 logfile for each access [Mark Cox]
14104 *) Fixed bug where Redirect in .htaccess files would cause memory
14105 leak. [Nathan Neulinger]
14107 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
14109 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
14111 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
14113 Changes with Apache 1.1.0
14115 *) Bring NeXT support up to date. [Takaaki Matsumoto]
14117 *) Bring QNX support up to date. [Ben Laurie]
14119 *) Make virtual hosts default to main server keepalive parameters.
14120 [Alexei Kosut, Ben Laurie]
14122 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
14124 *) Fix missing address family for connect, also remove unreachable statement
14125 in mod_proxy. [Ben Laurie]
14127 *) mod_env now turned on by default in Configuration.tmpl.
14129 *) Bugs which were fixed:
14130 a) yet more mod_proxy bugs [Ben Laurie]
14131 b) CGI works again with inetd [Alexei Kosut]
14132 c) Leading colons were stripped from passwords [<osm interguide.com>]
14133 d) Another fix to multi-method Limit problem [<jk tools.de>]
14135 Changes with Apache 1.1b4
14137 *) r->bytes_sent variable restored. [Robert Thau]
14139 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
14141 *) More possibly unsecure programs removed from the support directory.
14143 *) More mod_auth_msql authentication improvements.
14145 *) VirtualHosts based on Host: headers no longer conflict with the
14148 *) OS/2 compatibility enhancements. [Gary Smiley]
14150 *) POST now allowed to directory index CGI scripts.
14152 *) Actions now work with files of the default type.
14154 *) Bugs which were fixed:
14155 a) more mod_proxy bugs
14156 b) early termination of inetd requests
14157 c) compile warnings on several systems
14158 d) problems when scripts stop reading output early
14160 Changes with Apache 1.1b3
14162 *) Much of cgi-bin and all of cgi-src has been removed, due to
14163 various security holes found and that we could no longer support
14166 *) The "Set-Cookie" header is now special-cased to not merge multiple
14167 instances, since certain popular browsers can not handle multiple
14168 Set-Cookie instructions in a single header. [Paul Sutton]
14170 *) rprintf() added to buffer code, occurrences of sprintf removed.
14173 *) CONNECT method for proxy module, which means tunneling SSL should work.
14174 (No crypto needed) Also a NoCache config directive.
14176 *) Several API additions: pstrndup(), table_unset() and get_token()
14177 functions now available to modules.
14179 *) mod_imap fixups, in particular Location: headers are now complete
14182 *) New "info" module which reports on installed module set through a
14183 special URL, a la mod_status.
14185 *) "ServerPath" directive added - allows for graceful transition
14186 for Host:-header-based virtual hosts.
14188 *) Anonymous authentication module improvements.

14192 *) Status module design improved - output now table-based. [Ben Laurie]
14194 *) htdigest utility included for use with digest authentication
14197 *) mod_negotiation: Accept values with wildcards to be treated with
14198 less priority than those without wildcards at the same quality
14199 value. [Alexei Kosut]
14201 *) Bugs which were fixed:
14202 a) numerous mod_proxy bugs
14203 b) CGI early-termination bug [Ben Laurie]
14204 c) Keepalives not working with virtual hosts
14205 d) RefererIgnore problems
14206 e) closing fd's twice in mod_include (causing core dumps on
14207 Linux and elsewhere).
14209 Changes with Apache 1.1b2
14212 a) core dumps in mod_digest
14213 b) truncated hostnames/ip address in the logs
14214 c) relative URL's in mod_imap map files
14216 Changes with Apache 1.1b1
14218 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
14220 Changes with Apache 1.0.3
14222 *) Internal redirects which occur in mod_dir.c now preserve the
14223 query portion of a request (the bit after the question mark).
14226 *) Escape active characters '<', '>' and '&' in html output in
14227 directory listings, error messages and redirection links.
14230 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
14232 *) Fix for POSIX compliance in waiting for processes in alloc.c.
14235 *) setsockopt no longer takes a const declared argument [Martijn Koster]
14237 *) Reset timeout timer after each successful fwrite() to the network.
14238 This patch adds a reset_timeout() procedure that is called by
14239 send_fd() to reset the timeout ever time data is written to the net.
14242 *) timeout() signal handler now checks for SIGPIPE and reports
14243 lost connections in a more user friendly way. [Rob Hartill]
14245 *) Location of the "scoreboard" file which used to live in /tmp is
14246 now configurable (for OSes that can't use mmap) via ScoreBoardFile
14247 which works similar to PidFile (in httpd.conf) [Rob Hartill]
14249 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
14251 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
14252 which caused a SEGV with cookies enabled
14254 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
14257 *) Log the UNIX textual error returned by some system calls, in
14258 particular errors from accept() [David Robinson]
14260 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
14262 Changes with Apache 1.0.2
14264 *) patch to get Apache compiled on UnixWare 2.x, recommended as
14265 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
14267 *) Fix get_basic_auth_pw() to set the auth_type of the request.
14270 *) past changes to http_config.c to only use the
14271 setrlimit function on systems defining RLIMIT_NOFILE
14272 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
14273 for SUNOS and prototypes the needed functions.
14275 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
14278 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
14280 *) Merge multiple headers from CGI scripts instead of taking last
14281 one. [David Robinson]
14283 *) Add support for SCO 5. [Ben Laurie]
14285 Changes with Apache 1.0.1
14287 *) Silence mod_log_referer and mod_log_agent if not configured
14290 *) Recursive includes can occur if the client supplies PATH_INFO data
14291 and the server provider uses relative links; as file.html
14292 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
14294 *) The replacement for initgroups() did not call {set,end}grent(). This
14295 had two implications: if anything else used getgrent(), then
14296 initgroups() would fail, and it was consuming a file descriptor.
14299 *) On heavily loaded servers it was possible for the scoreboard to get
14300 out of sync with reality, as a result of a race condition.
14301 The observed symptoms are far more Apaches running than should
14302 be, and heavy system loads, generally followed by catastrophic
14303 system failure. [Ben Laurie]
14305 *) Fix typo in license. [David Robinson]
14307 Changes with Apache 1.0.0 23 Nov 1995
14309 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
14311 Changes with Apache 0.8.16 05 Nov 1995
14313 *) New man page for 'httpd' added to support directory [David Robinson]
14315 *) .htgroup files can have more than one line giving members for a
14316 given group (each must have the group name in front), for NCSA
14317 back-compatibility [Robert Thau]
14319 *) Mutual exclusion around accept() is on by default for SVR4 systems
14320 generally, since they generally can't handle multiple processes in
14321 accept() on the same socket. This should cure flaky behavior on
14322 a lot of those systems. [David Robinson]
14324 *) AddType, AddEncoding, and AddLanguage directives take multiple
14325 extensions on a single command line [David Robinson]
14327 *) UserDir can be disabled for a given virtual host by saying
14328 "UserDir disabled" in the <VirtualHost> section --- it was a bug
14329 that this didn't work. [David Robinson]
14331 *) Compiles on QNX [Ben Laurie]
14333 *) Corrected parsing of ctime time format [David Robinson]
14335 *) httpd does a perror() before exiting if it can't log its pid
14336 to the PidFile, to make diagnosing the error a bit easier.
14339 *) <!--#include file="..."--> can no longer include files in the
14340 parent directory, for NCSA back-compatibility. [David Robinson]
14342 *) '~' is *not* escaped in URIs generated for directory listings
14345 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
14347 *) Fixed bug involving handling URIs with escaped %-characters
14348 in redirects [David Robinson]
14350 Changes with Apache 0.8.15 14 Oct 1995
14352 *) Switched to new, simpler license
14354 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
14356 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
14358 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
14360 *) Correctly handles internal redirects to files with names containing '%'
14363 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
14365 *) Use geteuid() rather than getuid() to see if we have root privilege,
14366 so that server correctly resets privilege if run setuid root. [Andrew
14369 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
14372 *) Fix relative URLs in imagemap files [Randy Terbush]
14374 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
14377 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
14378 entries all name the same one. [David Robinson]
14380 *) Fix directory listings with filenames containing unusual characters
14383 *) Better URI-escaping for generated URIs in directories with filenames
14384 containing unusual characters [Ben Laurie]
14386 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
14388 *) Unblock alarms on error return from spawn_child() [David Robinson]
14390 *) Sample Config files have extra note for SCO users [Ben Laurie]
14392 *) Configuration has note for HP-UX users [Rob Hartill]
14394 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
14396 *) Nuked bogus #define in httpd.h [David Robinson]
14398 *) Better test for whether a system has setrlimit() [David Robinson]
14400 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
14402 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
14405 Changes with Apache 0.8.14 19 Sep 1995
14407 *) Compiles on SCO ODT 3.0 [Ben Laurie]
14409 *) AddDescription works (better) [Ben Laurie]
14411 *) Leaves an intelligible error diagnostic when it can't set group
14412 privileges on standalone startup [Andrew Wilson]
14414 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
14415 that machine, which claims to be BSD but does not support RLIMIT.
14418 *) gcc -Wall no longer complains about an unused variable when util.c
14419 is compiled with -DMINIMAL_DNS [Andrew Wilson]
14421 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
14423 Changes with Apache 0.8.13 07 Sep 1995
14425 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
14427 *) Have built-in imagemap code recognize & honor Point directive [James
14430 *) Generate cleaner directory listings in directories with a mix of
14431 long and short filenames [Rob Hartill]
14433 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
14435 *) Properly default ServerName for virtual servers [Robert Thau]
14437 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
14438 Paul Richards and a cast of thousands...]
14440 *) On self-identified BSD systems (we don't try to guess any more),
14441 allocate a few extra file descriptors per virtual host with setrlimit,
14442 if we can, to avoid running out. [Randy Terbush]
14444 *) Write 22-character lock file name into buffer with enough space
14445 on startup [Konstantin Olchanski]
14447 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
14450 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
14452 *) Suppress -Wall warning by initializing variable in negotiation code
14453 [Tobias Weingartner]
14455 Changes with Apache 0.8.12 31 Aug 1995
14457 *) Doesn't pause three seconds after including a CGI script which is
14458 too slow to die off (this is done by not even trying to kill off
14459 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
14460 after the entire document has been processed). [Robert Thau]
14462 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
14464 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
14466 *) Allows .htaccess files to override <Directory> sections naming the
14467 same directory [David Robinson]
14469 *) Removed an efficiency hack in sub_req_lookup_uri which was
14470 causing certain extremely marginal cases (e.g., ScriptAlias of a
14471 *particular* index.html file) to fail. [David Robinson]
14473 *) Doesn't log an error when the requested URI requires
14474 authentication, but no auth header line was supplied by the
14475 client; this is a normal condition (the client doesn't no auth is
14476 needed here yet). [Robert Thau]
14478 *) Behaves more sanely when the name server loses its mind [Sean Welch]
14480 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
14482 *) RFC931 code no longer passes out name of prior clients on current
14483 requests if the current request came from a server that doesn't
14484 do RFC931. [David Robinson]
14486 *) Configuration script accepts "Module" lines with trailing whitespace.
14489 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
14491 *) Cleaned up comments in mod_cgi.c [Robert Thau]
14493 Changes with Apache 0.8.11 24 Aug 1995
14495 *) Wildcard <Directory> specifications work. [Robert Thau]
14497 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
14499 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
14500 the file being requested itself, in addition to the directories leading
14501 up to it. [Robert Thau]
14503 *) Logs access failures due to symlink checks or invalid client address
14504 in the error log [Roy Fielding, Robert Thau]
14506 *) Symlink checks deal correctly with systems where lstat of
14507 "/path/to/some/link/" follows the link. [Thau, Fielding]
14509 *) Doesn't reset DirectoryIndex to 'index.html' when
14510 other directory options are set in a .htaccess file. [Robert Thau]
14512 *) Clarified init code and nuked bogus warning in mod_access.c
14513 [Florent Guillaume]
14515 *) Corrected several directives in sample srm.conf
14516 --- includes corrections to directory indexing icon-related directives
14517 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
14518 icons for encodings right, and turning on AddEncoding by default).
14521 *) Corrected descriptions of args to AddIcon and AddAlt in command table
14524 *) INSTALL & README mention "contributed modules" directory [Brian
14527 *) Fixed English in the license language... "for for" --> "for".
14530 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
14531 mod_alias.c, merging it almost completely with handling of Alias, and
14532 adding a 'notes' field to the request_rec which allows the CGI module
14533 to discover whether the Alias module has put this request through
14534 ScriptAlias (which it needs to know for back-compatibility, as the old
14535 NCSA code did not check Options ExecCGI in ScriptAlias directories).
14538 Changes with Apache 0.8.10 18 Aug 1995
14540 *) AllowOverride applies to the named directory, and not just
14541 subdirectories. [David Robinson]
14543 *) Do locking for accept() exclusion (on systems that need it)
14544 using a special file created for the purpose in /usr/tmp, and
14545 not the error log; using the error log causes real problems
14546 if it's NFS-mounted; this is known to be the cause of a whole
14547 lot of "server hang" problems with Solaris. [David Robinson;
14548 thanks to Merten Schumann for help diagnosing the problem].
14550 Changes with Apache 0.8.9 12 Aug 1995
14552 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
14554 *) Nested includes see environment variables of the including document,
14555 for NCSA bug-compatibility (some sites have standard footer includes
14556 which try to print out the last-modified date). [Eric Hagberg/Robert
14559 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
14560 URI as a CGI script, even if it would have been treated as something
14561 else if requested directly, for NCSA back-compatibility. (Note that
14562 this means that people who know the name of the script can see the
14563 code just by asking for it). [Robert Thau]
14565 *) New version of dbmmanage script included in support directory as
14568 *) Check if scoreboard file couldn't be opened, and say so, rather
14569 then going insane [David Robinson]
14571 *) POST to CGI works on A/UX [Jim Jagielski]
14573 *) AddIcon and AddAlt commands work properly [Rob Hartill]
14575 *) NCSA server push works properly --- the Arena bug compatibility
14576 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
14577 if you still want the workaround). [Rob Hartill]
14579 *) If client didn't submit any Accept-encodings, ignore encodings in
14580 content negotiation. (NB this will all have to be reworked anyway
14581 for the new HTTP draft). [Florent Guillaume]
14583 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
14585 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
14587 *) Give Redirect priority over Alias, for NCSA bug compatibility
14590 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
14591 paralleling earlier bug fix for CGI [David Robinson]
14593 *) If DBM auth is improperly configured, report a server error and don't
14596 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
14597 it seems to work well enough without it (even in a 10 hits/sec
14598 workout), and the overhead for the locking under A/UX is
14599 alarmingly high (though it is very low on other systems).
14600 [Eric Hagberg, Jim Jagielski]
14602 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
14604 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
14605 Behlendorf/Eric Hagberg]
14607 *) More improvements to default Configuration for A/UX [Jim Jagielski]
14609 *) Compiles clean on NEXT [Rob Hartill]
14611 *) Compiles clean on SGI [Robert Thau]
14613 Changes with Apache 0.8.8 08 Aug 1995
14615 *) SunOS library prototypes now never included unless explicitly
14616 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
14617 people using GNU libc on SunOS are screwed by prototypes for the
14620 (Those who wish to compile clean with gcc -Wall on a standard
14621 SunOS setup need the prototypes, and may obtain them using
14622 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
14623 with nonstandard libraries are presumably competent to make their
14626 *) Strips trailing '/' characters off both args to the Alias command,
14627 to make 'Alias /foo/ /bar/' work.
14629 Changes with Apache 0.8.7 03 Aug 1995
14631 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
14632 [reported by David Robinson]
14634 *) Compiles clean on OSF/1 [David Robinson]
14636 *) Added some of the more recent significant changes (AddLanguage stuff,
14637 experimental LogFormat support) to CHANGES file in distribution root
14640 Changes with Apache 0.8.6 02 Aug 1995
14642 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
14643 (If you actually wanted a conditional GET which bypassed the cache, you
14644 couldn't get it). [Reported by Roy Fielding]
14646 *) Properly terminate headers on '304 Not Modified' replies to conditional
14647 GETs --- no browser we can find cares much, but the CERN proxy chokes.
14648 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
14650 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
14652 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
14653 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
14654 and older versions don't set the __SUNPRO_C preprocessor variable). On
14655 all other systems, these are never used anyway. [Reported by Mark Cox].
14657 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
14659 Changes with Apache 0.8.5 01 Aug 1995
14661 *) Added last-minute configurable log experiment, as optional module
14663 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
14664 properly. (One-line fix to http_protocol.c).
14666 *) Work around bogus behavior when reloading from Netscape.
14667 It's Netscape's bug --- for some reason they expect a request with
14668 If-modified-since: to not function as a conditional GET if it also
14669 comes with Pragma: no-cache, which is way out of line with the HTTP
14670 spec (according to Roy Fielding, the redactor).
14672 *) Added parameter to set maximum number of server processes.
14674 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
14677 *) IdentityCheck bugfix [Chuck Murcko].
14679 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
14681 *) More sample config file corrections; add extension to AddType for
14682 *.asis, move AddType generic description to its proper place, and
14683 fix miscellaneous typos. [ Alexei Kosut ]
14685 *) Deleted the *other* reference to the regents from the Berkeley
14686 legal disclaimer (everyplace).
14688 *) Nuked Shambhala name from src/README; had already cleaned it out
14689 of everywhere else.
14691 Changes with Apache 0.8.4
14693 *) Changes to server-pool management parms --- renamed current
14694 StartServers to MinSpareServers, created separate StartServers
14695 parameter which means what it says, and renamed MaxServers to
14696 MaxSpareServers (though the old name still works, for NCSA 1.4
14697 back-compatibility). The old names were generally regarded as
14698 too confusing. Also altered "docs" in sample config files.
14700 *) More improvements to default config files ---
14701 sample directives (commented out) for XBitHack, BindAddress,
14702 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
14703 defaults, AddTypes for send-as-is and imagemap magic types, and
14704 improvements to samples for DirectoryIndex [Alexei Kosut]
14706 *) Yet more improvements to default config files --- changes to
14707 Alexei's sample AddLanguage directives, and sample LanguagePriority
14708 [ Florent Guillaume ]
14710 *) Set config file locations properly if not set in httpd.conf
14713 *) Don't escape URIs in internal redirects multiple times; don't
14714 do that when translating PATH_INFO to PATH_TRANSLATED either.
14717 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
14719 Changes with Apache 0.8.3
14721 *) Edited distribution README to *briefly* summarize installation
14722 procedures, and give a pointer to the INSTALL file in the src/
14725 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
14726 recent NCSA distributions.
14728 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
14729 exist for the same directory, use both and don't segfault. [Reported
14732 *) Proper makefile dependencies [David Robinson]
14734 *) Note (re)starts in error log --- reported by Rob Hartill.
14736 *) Only call no2slash() after get_path_info() has been done, to
14737 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
14738 reported by Andrew Wilson, though this one is probably a real bug]
14740 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
14741 dump core when Referer is not supplied. [Randy Terbush]
14743 *) Lightly edited sample config files to refer people to our documentation
14744 instead of NCSA's, and to list Rob McCool as *original* author (also
14745 deleted his old, and no doubt non-functional email address). Would be
14746 nice to have examples of new features...
14748 Changes with Apache 0.8.2 19 Jul 1995
14750 *) Added AddLanuage code [Florent Guillaume]
14752 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
14754 *) All sorts of problems when MultiViews finds a directory. It would
14755 be nice if mod_dir.c was robust enough to handle that, but for now,
14756 just punt. [reported by Brian Behlendorf]
14758 *) Wait for all children on restart, to make sure that the old socket
14759 is gone and we can reopen it. [reported by Randy Terbush]
14761 *) Imagemap module is enabled in default Configuration
14763 *) RefererLog and UserAgentLog modules properly default the logfile
14766 *) Mark Cox's mod_cookies added to the distribution as an optional
14767 module (commented out in the default Configuration, and noted as
14768 an experiment, along with mod_dld). [Mark Cox]
14770 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
14772 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
14774 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
14776 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
14779 Changes with Apache 0.8.1
14781 *) New imagemap module [Randy Terbush]
14783 *) Replacement referer log module with NCSA-compatible RefererIgnore
14784 [Matthew Gray again]
14786 *) Don't mung directory listings with very long filenames.
14787 [Florent Guillaume]
14789 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
14791 *) New config script. See INSTALL for info. [Robert Thau]
14793 *) Scoreboard mechanism for regulating the number of extant server
14794 processes. MaxServers and StartServers defaults are the same as
14795 for NCSA, but the meanings are slightly different. (Actually,
14796 I should probably lower the MaxServers default to 10).
14798 Before asking for a new connection, each server process checks
14799 the number of other servers which are also waiting for a
14800 connection. If there are more than MaxServers, it quietly dies
14801 off. Conversely, every second, the root, or caretaker, process
14802 looks to see how many servers are waiting for a new connection;
14803 if there are fewer than StartServers, it starts a new one. This
14804 does not depend on the number of server processes already extant.
14805 The accounting is arranged through a "scoreboard" file, named
14806 /tmp/htstatus.*, on which each process has an independent file
14807 descriptor (they need to seek without interference).
14809 The end effect is that MaxServers is the maximum number of
14810 servers on an *inactive* server machine, but more will be forked
14811 off to handle unusually heavy loads (or unusually slow clients);
14812 these will die off when they are no longer needed --- without
14813 reverting to the overhead of full forking operation. There is a
14814 hard maximum of 150 server processes compiled in, largely to
14815 avoid forking out of control and dragging the machine down.
14816 (This is arguably too high).
14818 In my server endurance tests, this mechanism did not appear to
14819 impose any significant overhead, even after I forced it to put the
14820 scoreboard file on a normal filesystem (which might have more
14821 overhead than tmpfs). [Robert Thau]
14823 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
14826 *) Read .htaccess files even in directory with <Directory> section.
14827 (Former incompatibility noted on mailing list, now fixed). [Robert
14830 *) "HEAD /" gives the client a "Bad Request" error message, rather
14831 than trying to send no body *and* no headers. [Cliff Skolnick].
14833 *) Don't produce double error reports for some very obscure cases
14834 mainly involving auth configuration (the "all modules decline to
14835 handle" case which is a sure sign of a server bug in most cases,
14836 but also happens when authentication is badly misconfigured).
14839 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
14840 it's *for*, and this sort of thing really shouldn't be cluttering
14841 up the Makefile). [Robert Thau]
14843 *) Incidental code cleanups in http_main.c --- stop dragging
14844 sa_client around; just declare it where used. [Robert Thau]
14846 *) Another acc-related fix. (It doesn't like const char
14847 in some places...). [Mark Cox]
14849 Changes with Shambhala 0.6.1 13 Jul 1995
14851 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
14852 Also, fixed auth typo in http_protocol.c unmasked by this fix.
14854 *) Compiles clean with acc on SunOS [Paul Sutton]
14856 *) Reordered modules in modules.c so that Redirect takes priority
14857 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
14858 believe it or not, he has an actual site with a ScriptAlias and
14859 a Redirect declared for the *exact same directory*. Even *my*
14860 compatibility fetish wouldn't motivate me to fix this if the fix
14861 required any effort, but it doesn't, so what the hey.
14863 *) Fixed to properly default several server_rec fields for virtual
14864 servers from the corresponding fields in the main server_rec.
14865 [Cliff Skolnick --- 'port' was a particular irritant].
14867 *) No longer kills off nph- child processes before they are
14868 finished sending output. [Matthew Gray]
14870 Changes with Shambhala 0.6.0 10 Jul 1995
14872 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
14873 the connection to the client in an "aborted" state, but otherwise
14874 allow whatever handlers are running to clean up. hard_timeout()s
14875 abort the request in progress completely; anything not tied to some
14876 resource pool cleanup will leak. They're still around because I
14877 haven't yet come up with a more elegant way of handling
14878 timeouts when talking to something that isn't the client. The
14879 default_handler and the dir_handler now use soft timeouts, largely
14880 so I can test the feature. [Robert Thau]
14882 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
14883 the case of log handlers dying prematurely is probably handled VERY
14884 gracelessly at this point, and if the logger stops reading input,
14885 the server will hang. (It is known to correctly restart the
14886 logging process on server restart; this is (should be!) going through
14887 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
14888 script). [Robert Thau]
14890 *) asis files supported (new module). [Robert Thau]
14892 *) IdentityCheck code is compiled in, but has not been tested. (I
14893 don't know anyone who runs identd). [Robert Thau]
14895 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
14896 came in with the request, for NCSA bug-compatibility. [Robert Thau]
14898 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
14900 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
14901 as timeouts are not in scope. [Robert Thau]
14903 *) quoted-string args in config files now handled correctly (doesn't drop
14904 the last character). [Robert Thau; reported by Randy Terbush]
14906 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
14907 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
14909 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
14910 default default type); the former default default behavior when all
14911 type-checkers defaulted had been a core dump. [Paul Sutton]
14913 *) Copy filenames out of the struct dirent when indexing
14914 directories. (On Linux, readdir() returns a pointer to the same
14915 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
14917 Changes with Shambhala 0.5.3 [not released]
14919 *) Default response handler notes "file not found" in the error log,
14920 if the file was not found. [Cliff Skolnick].
14922 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
14923 code no longer sets up bogus PATH_INFO which fakes out the directory
14924 handler). [Cliff Skolnick]
14926 Changes with Shambhala 0.5.2 06 Jul 1995
14928 *) Changes to http_main.c --- root server no longer plays silly
14929 games with SIGCHLD, and so now detects and replaces dying
14930 children. Child processes just die on SIGTERM, without taking
14931 the whole process group with them. Potential problem --- if any
14932 child process refuses to die, we hang in restart.
14933 MaxRequestsPerChild may still not work, but it certainly works
14934 better than it did before this! [Robert Thau]
14936 *) mod_dir.c bug fixes: ReadmeName and HeaderName
14937 work (or work better, at least); over-long description lines
14938 properly terminated. [Mark Cox]
14940 *) http_request.c now calls unescape_url() more places where it
14941 should [Paul Sutton].
14943 *) More directory handling bugs (reported by Cox)
14944 Parent Directory link is now set correctly. [Robert Thau]
14946 Changes with Shambhala 0.5.1 04 Jul 1995
14948 *) Generalized cleanup interface in alloc.c --- any function can be
14949 registered with alloc.c as a cleanup for a resource pool;
14950 tracking of files and file descriptors has been reimplemented in
14951 terms of this interface, so I can give it some sort of a test.
14954 *) More changes in alloc.c --- new cleanup_for_exec() function,
14955 which tracks down and closes all file descriptors which have been
14956 registered with the alloc.c machinery before the server exec()s a
14957 child process for CGI or <!--#exec-->. CGI children now get
14958 started with exactly three file descriptors open. Hopefully,
14959 this cures the problem Rob H. was having with overly persistent
14960 CGI connections. [Robert Thau]
14962 *) Mutual exclusion around the accept() in child_main() --- this is
14963 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
14964 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
14965 This uses fcntl(F_SETLK,...) on the error log descriptor because
14966 flock() on that descriptor won't work on systems which have BSD
14967 flock() semantics, including (I think) Linux 1.3 and Solaris.
14969 This does work on SunOS (when the server is idle, only one
14970 process in the pool is waiting on accept()); it *ought* to work
14971 on the other systems. [Robert Thau]
14973 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
14975 *) sizeof(*sa_client) bugfix from [Rob Hartill]
14977 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
14979 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
14980 be unnecessary if I go to the revised timeout-handling scheme).
14983 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
14984 string) even if none came in with the request. [Robert Thau]
14986 *) CHANGES file added to distribution ;-).
14988 Changes with Shambhala 0.4.5
14990 *) mod_dld --- early dynamic loading support [rst]
14991 *) Add wildcard content handlers for XBITHACK; default_hander now
14992 invoked with that mechanism (as a handler hanging off mod_core) [rst]
14993 *) XBITHACK supported as a wildcard content-handler, and
14994 configurable at run-time (not just at compile time, as in the
14995 "patchy server" releases) [rst]
14997 Changes with Shambhala 0.4.4 30 Jun 1995
14999 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
15000 *) Handle Addtype x/y .z [rst, reported by Cox]
15002 Changes with Shambhala 0.4.3
15004 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
15005 synonymous [rst, terbush]
15007 Changes with Shambhala 0.4.1 28 Jun 1995
15009 *) First-cut virtual host implementation; some refit in the config
15010 reading code, and log management, was necessary to support this [rst]
15011 *) Sub-pool machinery, originally added to avoid excessive storage
15012 allocation on listings of large directories (which turned out to
15013 be the problem that the 0.3 storage accounting was added to
15014 find). Subrequests and mod_dir changed to use subpools. [rst]
15015 *) More memory debugging --- free list consistency checks. [rst]
15016 *) Added err_headers to request_rec, with support elsewhere [rst]
15017 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
15019 Changes with Shambhala 0.3 19 Jun 1995
15021 *) Switch ONE_PROCESS to a runtime command-line option (-X)
15022 *) Don't compile in mod_ai_backcompat by default
15023 *) Switch name of server from Apache to Shambhala in Makefile
15024 *) Add some accounting routines to track memory usage in the pools,
15027 Changes with Shambhala 0.2
15029 *) Set DOCUMENT_ROOT CGI variable
15030 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
15031 *) Add critical section protection to handling of cleanup structures
15033 *) Significant code reorg within the server core to group related
15034 functions together [rst]
15035 *) Correctly handle clients that hang up before sending any request
15037 *) Replace dying child processes. [rst]
15039 Changes with Shambhala 0.1 12 Jun 1995
15041 Major rewrite of the pre-existing "patchy server" codebase, by
15042 Robert Thau (rst). Significant portions of the server code, such
15043 as configuration-file handling and HTTP authentication support,
15044 were ripped out and rewritten from scratch. Code that was not
15045 completely rewritten was significantly altered.
15047 Major changes with this release include:
15049 *) Introduction of the module API; in request handling, the central
15050 machinery just dispatches to various modules, which actually do
15051 most of the work. Configuration handling is similar --- modules
15052 declare their own commands, and the central machinery just
15053 dispatches to them.
15055 API features from shambhala/0.1 were substantially unchanged in
15056 Apache 1.0 and 1.1. (1.0 API features not yet present in this
15057 release, such as wildcard handlers and subpools, were added in
15058 subsequent Shambhala releases, and were also generally rst's
15061 *) This release included the following modules:
15063 mod_access (access control --- allow and deny directives),
15064 mod_alias (Alias and Redirect commands),
15065 mod_auth (straight HTTP authentication, based on flat-files)
15066 mod_auth_dbm (same, with dbm files)
15067 mod_cgi (CGI scripts and, in this release, ScriptAlias)
15068 mod_common_log (CLF access logs; later renamed mod_log_common)
15069 mod_dir (directory indexing)
15070 mod_include (server-side includes)
15071 mod_mime (AddType directives)
15072 mod_negotiation (content negotiation)
15073 mod_userdir (support for users' public_html directories)
15075 It also included a mod_ai_backcompat, which was a private hack
15076 for back-compatibility with rst's own AI-lab servers.
15078 All of these modules were substantially complete, and functional
15079 or nearly so (a few, which implemented features not in use at
15080 Thau's site, required patches of a few lines).
15082 *) sub-request machinery, to allow modules to determine how other
15083 modules would assign MIME types to a given file, or optionally
15084 serve its content (this is heavily used by mod_dir, mod_include
15085 and mod_negotiation).
15087 *) Resource pool system for keeping track of memory allocated and
15088 files opened in service of a particular request. Much of the
15089 code in the modules (when they weren't rewrites) was adjusted to
15090 replace a pervasive convention of using fixed-size buffers on
15091 the stack with an equally pervasive convention of using memory
15092 allocated with palloc().
15094 *) Reorganization of data structures associated with a given
15095 request to eliminate use of global variables and the troublesome
15096 unmunge_name function (used in NCSA and early Apache releases to
15097 attempt to determine the URI which mapped to a given filename
15098 --- a difficult proposition, given that it is easy to produce
15099 setups in which multiple URIs map to the same file).
15101 *) Source files renamed and rearranged
15103 *) Very simple pre-forking behavior --- parent process forked off a
15104 fixed number of children, and then just waited for SIGHUP.
15106 *) Other more minor changes too numerous to list.
15108 This release included modified versions of a lot of code from the
15109 Apache 0.6.4 public release, plus an early pre-forking patch
15110 codeveloped by Robert Thau and Rob Hartill.
15112 Changes with Apache 0.7.3 20 Jun 1995
15114 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
15115 were incorporated by Rob Hartill on the main branch while Robert Thau
15116 worked on the Shambhala rewrite above. Most were merged into the
15117 Shambala architecture after Apache 0.8.0.
