2 Changes with Apache 2.3.0
3 [Remove entries to the current 2.0 and 2.2 section below, when backported]
5 *) mod_cache: Make caching of reverse proxies possible again. PR 38017.
8 *) Refactored ap_read_request() to provide a foundation for
9 nonblocking reads of requests. [Brian Pane]
11 *) If a connection is aborted while waiting for a chunked line, flag the
12 connection as errored out. [Justin Erenkrantz]
14 *) mod_proxy: If we get an error reading the upstream response,
16 [Justin Erenkrantz, Roy T. Fielding, Jim Jagielski, Ruediger Pluem]

20 *) Fix typo in ProxyStatus syntax error message.
21 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
23 *) Asynchronous write completion for the Event MPM. [Brian Pane]
25 *) Added an End-Of-Request bucket type. The logging of a request and
26 the freeing of its pool are now done when the EOR bucket is destroyed.
27 This has the effect of delaying the logging until right after the last
28 of the response is sent; ap_core_output_filter() calls the access logger
29 indirectly when it destroys the EOR bucket. [Brian Pane]
31 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
32 and the format of statistical output has changed. [Colm MacCarthaigh]
34 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
36 *) Added new connection states for handler and write completion
39 *) New module: mod_authn_dbd [Nick Kew]
41 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
44 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
45 allowing string-valued client certificate attributes to be used for
46 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
47 [Martin Kraemer, David Reid]
49 Changes with Apache 2.2.1
51 *) SECURITY: CVE-2005-3357 (cve.mitre.org)
52 mod_ssl: Fix a possible crash during access control checks if a
53 non-SSL request is processed for an SSL vhost (such as the
54 "HTTP request received on SSL port" error message when an 400
55 ErrorDocument is configured, or if using "SSLEngine optional").
56 PR 37791. [Rüdiger Plüm, Joe Orton]
58 *) Chunk filter: Fix chunk filter to create correct chunks in the case that
59 a flush bucket is surrounded by data buckets. [Ruediger Pluem]

88 AuthDigestProvider. [Joshua Slive, Justin Erenkrantz]
90 *) Add in new UseCanonicalPhysicalPort directive, which controls
91 whether or not Apache will ever use the actual physical port
92 when constructing the canonical port number. [Jim Jagielski]
94 *) mod_dav: Fix a null pointer dereference in an error code path during the
96 [Ruediger Pluem, Ghassan Misherghi <ghassanm ucdavis.edu>]
98 *) Fix DESTDIR=... installation when using bundled copy of APR.
99 [Torsten Foertsch <torsten.foertsch gmx.net>]
101 *) mod_proxy_balancer: When finding best worker, use case insensitive
102 match for scheme and host, but case sensitive for the rest of
103 the path. [Jim Jagielski, Ruediger Pluem]
105 Changes with Apache 2.1.9
107 *) mod_proxy_ajp: Do not spool the entire response from AJP backend before
108 sending it up the filter chain. PR37100. [Ruediger Pluem]

111 only differ by the type from CACHE_OUT / CACHE_SAVE to ensure that
112 subrequests to non local resources work again. [Ruediger Pluem]
114 *) mod_proxy: Do not lowercase the entire worker name of a BalancerMember
115 since this breaks case sensitive URI's. PR36906. [Ruediger Pluem]
117 *) core: AddOutputFilterByType is ignored for proxied requests. PR31226.
118 [Joe Orton, Ruediger Pluem]

124 *) mod_proxy_balancer: BalancerManager and proxies correctly handle
125 member workers with paths. PR36816. [Ruediger Pluem, Jim Jagielski]
127 *) mod_log_config: %{hextid}P will log the thread id in hex with APR
128 versions 1.2.0 or higher. [Jeff Trawick]
130 *) httpd.exe/apachectl -V: display the DYNAMIC_MODULE_LIMIT setting, as
131 in 1.3. [Jeff Trawick]
133 *) Support dbd connections tied to the conn_rec [Nick Kew]
135 *) Move mod_dbd to /modules/database/ [Nick Kew]

143 [William Barker <william.barker wilshire.com>, Ruediger Pluem]
145 *) Elimiated the NET_TIME filter, restructuring the timeout logic.
146 This provides a working mod_echo on all platforms, and ensures any
147 custom protocol module is at least given an initial timeout value
148 based on the <VirtualHost > context's Timeout directive.
151 *) mod_proxy: Run the request_status hook also if there are no free workers
152 or all workers are in error state.
153 [Ruediger Pluem, Brian Akins <brian.akins turner.com>]
155 *) mod_proxy_balancer: mod_proxy_balancer does not handle sticky sessions

377 for UseCanonicalName to Off.
380 *) mod_userdir: The module no longer does any remapping unless the
381 UserDir directive is present in the config file.
384 *) Massively simplify the distributed httpd.conf by removing
385 many features and many directives that are at their default
386 setting. Add a selection of example config excerpts for adding

525 which sometimes prevented proxy-sendchunks from working.
528 *) Fix the RPM spec file so that an RPM build now works. An RPM

597 take advantage of LDAP authorization only [PR 28253]
598 [Jari Ahonen jah progress.com, Brad Nicholes]
600 *) Log the client IP address when an error occurs disabling nagle on a
601 connection, but log at a severity of debug since this error
602 generally means that the connection was dropped before data was
603 sent. Log the client IP address when reporting errors in the core
604 output filter. [Jeff Trawick]
606 *) core: Add a warning message if the request line read fails.
609 *) mod_rewrite: Removed the MaxRedirects option in favor of the
610 core LimitInternalRecursion directive. [André Malo]

630 [Jan Kratochvil <rcpt-dev.AT.httpd.apache.org jankratochvil.net>]
632 *) Restructured mod_auth_ldap to fit the new authentication model.
633 The module is now called authnz_ldap and has been moved out of
634 the modules/experimental area and into modules/aaa with the other
635 auth modules. Both the authn_ldap provider and the authz_ldap
636 handler are contained within the authnz_ldap module. The

2305 *) SECURITY: CVE-2003-0132 (cve.mitre.org)
2306 Close a Denial of Service vulnerability identified by David
2307 Endler <DEndler iDefense.com> on all platforms. An unlimited
2308 stream of newlines were acceptable between requests where each
2309 <lf> would allocate an 80 byte buffer, leading very quickly to
2310 memory exahustion. [Brian Pane]
2312 *) Added an rpm build script.

2315 *) Simpler, faster code path for request header scanning [Brian Pane]
2317 *) SECURITY: Eliminated leaks of several file descriptors to child
2318 processes, such as CGI scripts. This fix depends on the APR library
2319 release 0.9.2 or later (0.9.3 was distributed with the httpd
2320 source tarball for Apache 2.0.45.) PR 17206

2355 *) Improve binary compatibility of the core between debug (aka
2356 maintainer-mode) and a non-debug compile.
2359 *) mod_usertrack: don't set the cookie in subrequests. This works
2360 around the problem that cookies were set twice during fast internal
2361 redirects. PR 13211. [André Malo]
2363 *) mod_autoindex no longer forgets output format and enabled version
2364 sort in linked column headers. [André Malo]
2366 *) Use .sv instead of .se as extension for Swedish documents in the
2367 default configuration. PR 12877. [André Malo]
2369 *) Updated mod_ldap and mod_auth_ldap to support the Novell LDAP SDK SSL
2370 and standardized the LDAP SSL support across the various LDAP SDKs.
2371 Isolated the SSL functionality to mod_ldap rather than speading it
2372 across mod_auth_ldap and mod_ldap. Also added LDAPTrustedCA
2373 and LDAPTrustedCAType directives to mod_ldap to allow for a more
2374 common method of specifying the SSL certificate.
2375 [Dave Ward, Brad Nicholes]
2377 *) Fixed mod_ssl's SSLCertificateChain initialization to no longer
2378 skip the first cert of the chain by default. This misbehavior

2397 *) Enhance the behavior of mod_isapi's WriteClient() callback to
2398 provide better emulation for isapi modules that presume that the
2399 first WriteClient() call may send status and headers. An example
2400 of WriteClient() abuse is the foxisapi module, which relies on
2401 that assumpion and now works. [William Rowe, Milan Kosina]
2403 *) Check the return value of ap_run_pre_connection(). So if the
2404 pre_connection phase fails (without setting c->aborted)
2405 ap_run_process_connection is not executed. [Stas Bekman]
2407 *) Fixed a problem with mod_ldap which caused it to fault when caching
2408 was disabled. Needed to make sure that the code did not
2409 attempt to use the cache if it didn't exist. Also fixed some memory
2410 leaks which were due to not releasing LDAP resources on error
2411 conditions. [Brad Nicholes]
2413 *) Hook mod_proxy's fixup before mod_rewrite's fixup, so that by
2414 mod_rewrite proxied URLs will not be escaped accidentally by
2415 mod_proxy's fixup. PR 16368 [André Malo]
2417 *) While processing filters on internal redirects, remember seen EOS
2418 buckets also in the request structure of the redirect issuer(s). This
2419 prevents filters (such as mod_deflate) from adding garbage to the
2420 response. PR 14451. [André Malo]

2483 (or SymlinksIfOwnermatch) is set. PR 12395. [André Malo]
2485 *) apxs: Include any special APR ld flags when linking the DSO.
2486 This resolves problems on AIX when building a DSO with apxs+gcc.
2489 *) Added character set support to mod_auth_LDAP to allow it to
2490 convert extended characters used in the user ID to UTF-8
2491 before authenticating against the LDAP directory. The new
2492 directive AuthLDAPCharsetConfig is used to specify the config
2493 file that contains the character set conversion table.

2524 *) Reorder the definitions for mod_ldap and mod_auth_ldap within
2525 config.m4 to make sure the parent mod_ldap is defined first.
2526 This ensures that mod_ldap comes before mod_auth_ldap in the
2527 httpd.conf file, which is necessary for mod_auth_ldap to load.

2530 *) Fix the building of cgi command lines when the query string
2531 contains '='. PR 13914 [Ville Skyttä <ville.skytta iki.fi>,
2534 *) Rename CacheMaxStreamingBuffer to MCacheMaxStreamingBuffer. Move
2535 implementation of MCacheMaxStreamingBuffer from mod_cache to
2536 mod_mem_cache. MCacheMaxStreamingBuffer now defaults to the
2537 lesser of 100,000 bytes or MCacheMaxCacheObjectSize. This should
2538 eliminate the need for explicitly coding MCacheMaxStreamingBuffer
2539 in most configurations. [Bill Stoddard]
2541 *) mod_cache: Fix PR 15113, a core dump in cache_in_filter when
2542 a redirect occurs. The code was passing a format string and
2543 integer to apr_pstrcat. Changed to apr_psprintf.
2546 *) Replace APU_HAS_LDAPSSL_CLIENT_INIT with APU_HAS_LDAP_NETSCAPE_SSL
2547 as set by apr-util in util_ldap.c. This should allow mod_ldap
2548 to work with the Netscape/Mozilla LDAP library. [Øyvin Sømme

2565 for negotated type-map "Body:" responses (such as the error
2566 pages.) [André Malo <nd perlig.de>]
2568 *) mod_log_config: Allow '%%' escaping in CustomLog format
2569 strings to insert a literal, single '%'.

2572 *) mod_autoindex: AddDescription directives for directories
2573 now work as in Apache 1.3, where no trailing '/' is
2574 specified on the directory name. Previously, the trailing
2575 '/' *had* to be specified, which was incompatible with
2576 Apache 1.3. PR 7990 [Jeff Trawick]
2578 *) Fix for PR 14556. The expiry calculations in mod_cache were
2579 trying to perform "now + ((date - lastmod) * factor)" where
2580 date == lastmod resulting in "now + 0". The code now follows
2581 the else path (using the default expiration) if date is
2582 equal to lastmod. [Sergey <rx armstrike.com>, Paul J. Reder]
2584 *) Use AP_DECLARE in the debug versions of ap_strXXX in case the
2585 default calling convention is not the same as the one used by

2602 *) Add --[enable|disable]-v4-mapped configure option to control
2603 whether or not Apache expects to handle IPv4 connections
2604 on IPv6 listening sockets. Either setting will work on
2605 systems with the IPV6_V6ONLY socket option. --enable-v4-mapped
2606 must be used on systems that always allow IPv4 connections on
2607 IPv6 listening sockets. PR 14037 (Bugzilla), PR 7492 (Gnats)
2610 *) This fixes a problem where the underlying cache code
2611 indicated that there was one more element on the cache
2612 than there actually was. This happened since element 0
2613 exists but is not used. This code allocates the correct
2614 number of useable elements and reports the number of
2615 actually used elements. The previous code only allowed
2616 MCacheMaxObjectCount-1 objects to be stored in the
2617 cache. [Paul J. Reder]

2709 value at config time. This saves a lot of wasted processing
2710 if the mod_disk_cache module is loaded but no CacheRoot

2832 [Joe Orton <jorton redhat.com>]
2834 *) mod_cache: cache_storage.c. Add the hostname and any request
2835 args to the key generated for caching. This provides a unique
2836 key for each virtual host and for each request with unique
2837 args. [Paul J. Reder, args code provided by Kris Verbeeck]

2880 [Ian Holsman / Rob Cromwell <apachechangelog robcromwell.com>]
2882 *) The content-length filter no longer tries to buffer up
2883 the entire output of a long-running request before sending
2884 anything to the client. [Brian Pane]
2886 *) Win32: Lower the default stack size from 1MB to 256K. This will
2887 allow around 8000 threads to be started per child process.
2888 'EDITBIN /STACK:size apache.exe' can be used to change this
2889 value directly in the apache.exe executable.

2939 *) mod_disk_cache works much better. This module should still
2940 be considered experimental. [Eric Prud'hommeaux]
2942 *) Performance improvement for keepalive requests: when setting
2943 aside a small file for potential concatenation with the next
2944 response on the connection, set aside the file descriptor rather
2945 than copying the file into the heap. [Brian Pane]
2947 *) Modified version check on openssl so that it finds the executable
2948 first and then performs a check of the version, only warning the
2949 user if they chose, or we selected, an old version of OpenSSL.
2950 This change also allows the code to work for non-openssl libraries
2951 selected via the --with-ssl=dir option, which can override the
2952 automated library check in any case. [Roy Fielding]
2954 Changes with Apache 2.0.40
2956 *) SECURITY: CVE-2002-0661 (cve.mitre.org)
2957 Close a very significant security hole that
2958 applies only to the Win32, OS2 and Netware platforms. Unix was not
2959 affected, Cygwin may be affected. Certain URIs will bypass security
2960 and allow users to invoke or access any file depending on the system
2961 configuration. Without upgrading, a single .conf change will close
2962 the vulnerability. Add the following directive in the global server
2963 httpd.conf context before any other Alias or Redirect directives;
2964 RedirectMatch 400 "\\\.\."
2965 Reported by Auriemma Luigi <bugtest sitoverde.com>.
2968 *) SECURITY: CVE-2002-0654 (cve.mitre.org)
2969 Close a path-revealing exposure in multiview type
2970 map negotiation (such as the default error documents) where the
2971 module would report the full path of the typemapped .var file when
2972 multiple documents or no documents could be served based on the mime
2973 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
2976 *) SECURITY: CVE-2002-0654 (cve.mitre.org)
2977 Close a path-revealing exposure in cgi/cgid when we
2978 fail to invoke a script. The modules would report "couldn't create
2979 child process /path-to-script/script.pl" revealing the full path
2980 of the script. Reported by Jim Race <jrace qualys.com>.
2983 *) Set aside the apr-iconv and apr_xlate() features for the Win32
2984 build of 2.0.40 so development can be completed. A patch, from
2985 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
2986 will be available for those that wish to work with apr-iconv.
2989 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
2990 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
2992 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
2993 set to 1, so we can exclude things from the general case with
2994 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
2996 *) Accept multiple leading /'s for requests within the DocumentRoot.
2997 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
2999 *) Solved the reports of .pdf byterange failures on Win32 alone.
3000 APR's sendfile for the win32 platform collapses header and trailer
3001 buffers into a single buffer. However, we destroyed the pointers
3002 to the header buffer if a trailer buffer was present. PR 10781
3005 *) mod_ext_filter: Add the ability to enable or disable a filter via
3006 an environment variable. Add the ability to register a filter of
3007 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
3009 *) Restore the ability to specify host names on Listen directives.
3010 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh yahoo.com>]
3012 *) When deciding on the default address family for listening sockets,
3013 make sure we can actually bind to an AF_INET6 socket before
3014 deciding that we should default to AF_INET6. This fixes a startup
3015 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
3017 *) Replace usage of atol() to parse strings when we might want a
3018 larger-than-long value with apr_atoll(), which returns long long.
3019 This allows HTTPD to deal with larger files correctly.
3020 [Shantonu Sen <ssen apple.com>]
3022 *) mod_ext_filter: Ignore any content-type parameters when checking if
3023 the response should be filtered. Previously, "intype=text/html"
3024 wouldn't match something like "text/html;charset=8859_1".
3027 *) mod_ext_filter: Set up environment variables for external programs.
3028 [Craig Sebenik <craig netapp.com>]
3030 *) Modified the HTTP_IN filter to immediately append the EOS (end of
3031 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
3032 the caller to determine that no content remains without prefetching
3033 additional POST body. [William Rowe]

3052 and MSVC now trust that the project is current (when it is).
3053 [James Cox <imajes php.net>]
3055 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
3056 [Arthur P. Smith <apsmith aps.org>, Jeff Trawick]
3058 *) APR-Util Renames pending have been completed [Thom May]
3060 *) Performance improvements for the code that reads request
3061 headers (ap_rgetline_core() and related functions) [Brian Pane]
3063 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
3064 to configure the maximum amount of memory the allocators will
3065 hold on to for reuse. Anything over the MaxMemFree threshold
3066 will be free()d. This directive is useful when uncommon large
3067 peaks occur in memory usage. It should _not_ be used to mask
3068 defective modules' memory use. [Sander Striker]
3070 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
3071 scripts would not result in a truncated response.
3072 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
3074 *) Add a filter_init parameter to the filter registration functions
3075 so that a filter can execute arbitrary code before the handlers
3076 are invoked. This resolves a problem where mod_include requests
3077 would incorrectly return a 304. [Justin Erenkrantz]
3079 *) Fix a long-standing bug in 2.0, CGI scripts were being called
3080 with relative paths instead of absolute paths. Apache 1.3 used
3081 absolute paths for everything except for SuExec, this brings back
3082 that standard. [Ryan Bloom]
3084 *) Fix infinite loop due to two HTTP_IN filters being present for
3085 internally redirected requests. PR 10146. [Justin Erenkrantz]
3087 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
3090 *) Fix mod_ext_filter to look in the main server for filter definitions
3091 when running in a vhost if the filter definition is not found in
3092 the vhost. PR 10147 [Jeff Trawick]
3094 *) Support WinNT CGI invocation through ScriptInterpreterSource
3095 'registry' for script interpreter paths and names with non-ascii
3096 characters in the executable filepath. [William Rowe]
3098 *) Support the -w flag on to keep the Win32 console open on error.
3101 *) Normalize the hostname value in the request_rec to all-lowercase
3102 [Perry Harrington <pedward webcom.com>]
3104 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
3105 extended characters (non US-ASCII) in non-utf8 format. This brings
3106 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
3107 to the cgi application itself. [William Rowe]
3109 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
3110 modules to bring them up to the current apr/apr-util APIs.
3113 *) Fix segfault in mod_mem_cache most frequently observed when
3114 serving the same file to multiple clients on an MP machine.
3117 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
3118 [Brian Degenhardt <bmd mp3.com>, Ian Holsman]
3120 *) Fix perchild to work with apachectl by adding -k support to perchild.
3121 PR 10074 [Jeff Trawick]
3123 *) Fix a silly htpasswd.c logic error that incorrectly reported that
3124 both -c and -n had been used. PR 9989 [Cliff Woolley]
3126 *) Fixed a mod_include error case in which no HTTP response was sent
3127 to the client if an shtml document contained an unterminated SSI
3128 directive [Brian Pane]
3130 *) Improve ap_get_client_block implementation by using APR-util brigade
3131 helper functions and relying on current filter assumptions.
3134 Changes with Apache 2.0.39
3136 *) Fixed a build problem in htpasswd.c on Win32.
3137 [Guenter Knauf <eflash gmx.net>, Cliff Woolley]
3139 Changes with Apache 2.0.38
3141 *) Rewrite htpasswd to use APR. The removes the annoying warning about
3142 tmpnam being unsafe. [Ryan Bloom]
3144 *) We must set the MIME-type for .shtml files to text/html if we want them
3145 to be parsed for SSI tags. Add the config for that to the default
3146 config file so that it is easier to enable .shtml parsing.
3147 [Dave Dyer <ddyer real-me.net>]
3149 *) Fixed a problem with 'make install' on ReliantUnix.
3150 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
3152 *) Make the default_handler catch all requests that aren't served by
3153 another handler. This also gets us to return a 404 if a directory
3154 is requested, there is no DirectoryIndex, and mod_autoindex isn't
3155 loaded. [Justin Erenkrantz]
3157 *) Fixed the handling of nested if-statements in shtml files.
3158 PR 9866 [Brian Pane]
3160 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
3161 into a directory different from the one that was configured. This
3162 also mirrors the root= feature from 1.3. We cannot use prefix=,
3163 because both APR and APR-util resolve their installation paths at
3164 configuration time. This means that there is no variable prefix
3165 to replace. [Andreas Hasenack <andreas netbank.com.br>]
3167 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
3168 These levels of AIX don't have a thundering herd problem with
3169 accept(). [Jeff Trawick]
3171 *) prefork MPM: Ignore mutex errors during graceful restart. For
3172 certain types of mutexes (particularly SysV semaphores), we
3173 should expect to occasionally fail to obtain or release the
3174 mutex during restart processing. [Jeff Trawick]
3176 *) Fix install-bindist.sh so that it finds any perl instead of just
3177 early perl 5.x versions. This is consistent with a build/install
3178 from source, and it allows the perl scripts installed by a bindist
3179 to work on systems with perl 5.6. [Jeff Trawick]
3181 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
3182 Tru64 (and probably some other platforms). [Jeff Trawick]
3184 *) Allow CGI scripts to return their Content-Length. This also fixes a
3185 hang on HEAD requests seen on certain platforms (such as FreeBSD).
3188 *) Added log rotation based on file size to the RotateLog support
3189 utility. [Brad Nicholes]
3191 *) Fix some casting in mod_rewrite which broke random maps.
3192 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
3194 Changes with Apache 2.0.37
3196 *) allow POST method over SSL when per-directory client cert
3197 authentication is used with 'SSLOptions +OptRenegotiate' enabled
3198 and a client cert was found in the ssl session cache.
3200 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
3201 session cache when there is no cert chain in the cache. prior to
3202 the fix this situation would result in a FORBIDDEN response and
3203 error message "Cannot find peer certificate chain"
3206 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
3207 one was already sent. PR 9644 [Jeff Trawick]

3215 Solves the case of ServerRoot /foo paths where /foo was not
3216 on the same drive as /winnt/system32. [William Rowe]
3218 *) Make 2.0's "AcceptMutex" startup message now "completely"
3219 match how 1.3 does it. [Jim Jagielski]
3221 *) Implement a fixed size memory cache using a priority queue
3224 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
3225 querying certain other variables from config_vars.mk. PR 9316
3228 *) Added the "detached" attribute to the cgi_exec_info_t internals
3229 so that Win32 and Netware won't create a new window or console
3230 for each CGI invoked. PR 8387
3231 [Brad Nicholes, William Rowe]
3233 *) Consolidated the command line parameters and attributes that are
3234 manipulated by the optional function ap_cgi_build_command() in
3235 mod_cgi into a single structure.
3238 *) Get rid of uninitialized value errors with "apxs -q" on certain
3239 variables. [Stas Bekman <stas stason.org>]

3242 besides server-root/build. PR 8453
3243 [Jeff Trawick and a host of others]
3245 *) Allow ap_discard_request_body to be called multiple times in the
3246 same request. Essentially, ap_http_filter keeps track of whether
3247 it has sent an EOS bucket up the stack, if so, it will only ever
3248 send an EOS bucket for this request.
3249 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
3251 *) Remove all special mod_ssl URIs. This also fixes the bug where
3252 redirecting (.*) will allow an SSL protected page to be viewed
3253 without SSL. [Ryan Bloom]
3255 *) Fix the binary build install script so that the build logic
3256 created by "apxs -g" will work when the user has a binary
3257 build. [Jeff Trawick]
3259 *) Allow instdso.sh to work with full paths to the shared module.
3262 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
3263 in module for NetWare [Brad Nicholes]
3265 *) Changed cgi and piped log behavior to accept 65536 characters
3266 on Win32 (matching Linux) before deadlocking between outputing
3267 client stdin, slurping the output from stdout and then the stderr
3268 stream. PR 8179 [William Rowe]
3270 *) Fixed Win32 wintty.exe support to assure the window title is valid.
3271 Elimiates possible gpfault or garbage title without the -t option.
3274 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
3275 brigades and input filters. [Justin Erenkrantz]
3277 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
3278 body. [Justin Erenkrantz]
3280 *) NetWare: Piping log entries through RotateLogs using the
3281 CustomLogs directive is finally supported now that we have

3302 large amounts of data to be buffered. [Cliff Woolley]
3304 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
3305 stripping the content_type from cached responses.
3308 *) apachectl passes through any httpd options. Note: apachectl
3309 should be used in preference to httpd since it ensures that any
3310 appropriate environment variables have been set up.

3361 certificates, if truly desired, can be generated using openssl
3362 commands. PR 8724. [Cliff Woolley]
3364 *) Remove SSLLog and SSLLogLevel directives in favor of having
3365 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
3367 *) OS/390: LIBPATH no longer has to be manually uncommented in

3541 Added the APLOG_TOCLIENT flag to ap_log_rerror() to
3542 explicitly tell the server that warning messages should be sent
3543 to the client in addition to being recorded in the error log.
3544 Prior to this change, ap_log_rerror() always sent warning
3545 messages to the client. In one case, a faulty CGI script caused
3546 the server to send a warning message to the client that contained
3547 the full path to the CGI script. This could be considered a
3548 minor security exposure. [Bill Stoddard]

3676 cause the Apache parent process to run in the foreground (similar to
3677 -DNO_DETACH except that it doesn't switch session ids).
3680 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
3681 for those platforms that support it. If using the default
3682 implementation, this is between pthread and sysvsem in priority.
3683 This implies it's the new default for Darwin. [Jim Jagielski]
3685 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
3686 environment variables in the envvars file. [Jeff Trawick]
3688 *) worker MPM: Don't create a listener thread until we have a worker

3768 *) Fix a mod_cgid problem that left daemon processes stranded
3769 in some server restart scenarios. [Jeff Trawick]
3771 *) Added exp_foo and rel_foo variables to config_vars.mk for
3772 all Apache and Autoconf path variables (like --sysconfdir,
3773 --sbindir, etc). exp_foo is the "expanded" version, which means
3774 that all internal variable references have been interpolated.
3775 rel_foo is the same as $exp_foo, only relative to $prefix if they
3776 share a common path. [Aaron Bannert]
3778 *) Fix some restart/terminate problems in the worker MPM. Don't
3779 drop connections during graceful restart. [Jeff Trawick]

3867 *) Modify receive/send loop in proxy_http and proxy_ftp so that
3868 should it be necessary, the remote server socket is closed before
3869 transmitting the last buffer (set by ProxyIOBufferSize) to the
3870 client. This prevents the backend server from being forced to hang
3871 around while the last few bytes are transmitted to a slow client.
3872 Fix the case where no error checking was performed on the final
3873 brigade in the loop. [Graham Leggett]

3914 this allows mod_ssl to be added to a server that is already
3915 running and makes it possible to add/change certs/keys after the
3916 server has been started. [Doug MacEachern]
3918 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.

3944 to one of the following new lock APIs: apr_thread_mutex.h,
3945 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
3946 use the apr_lock.h API, as the old API will soon be deprecated.

3952 *) mod-include: make it handle flush'es and fix the 'false-alarm'
3953 [Justin Erenkrantz, Brian Pane, Ian Holsman]
3955 *) ap_get_*_filter_handle() functions to allow 3rd party modules
3956 to lookup filter handles so they can bypass the filter name
3957 lookup when adding filters to a request (via ap_add_*_filter_handle())
3958 [Ryan Morgan <rmorgan covalent.net>]
3960 *) Fix for multiple file buckets on Win32, where the first file
3961 bucket would cause the immediate closure of the socket on any
3962 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
3964 *) Correct Win32 failure of mmap of a segment beyond start of the
3965 file; fixes large SSL and similar transfers. [William Rowe]
3968 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
3969 multi-process mode to not "daemonize" while detaching from the
3970 controlling terminal. This is necessary for Apache to work with
3971 process-management tools like AIX's "System Resource Controller"
3972 as well as Dan Bernstein's "daemontools".
3973 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
3975 *) Convert mod_auth_digest to use the new apr_global_mutex_t
3976 type. [Aaron Bannert]
3978 *) fix bug in mod-include where it wouldn't send a unmatched
3979 part if it was at the end of a bucket [Ian Holsman]
3981 *) worker MPM: Improve logging of errors with the interface between
3982 the listener thread and worker threads. [Jeff Trawick]
3984 *) Some browsers ignore cookies that have been merged into a
3985 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
3986 are now unmerged in the http proxy before being sent to the
3987 client. [Graham Leggett]
3989 *) Fix a problem with proxy where each entry of a duplicated
3990 header such as Set-Cookie would overwrite and obliterate the
3991 previous value of the header, resulting in multiple header
3992 values (like cookies) going missing.
3993 [Graham Leggett, Joshua Slive]
3995 *) Add the server-limit and thread-limit values to the scoreboard
3996 for the sake of third-party applications.
3997 [Adam Sussman <myddryn vishnu.vidya.com>]
3999 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
4001 *) OS/390: Get make install to properly copy DSO modules.
4004 *) Win32: Fix bug in mod_status with displaying "Restart Time"
4005 and "Server uptime".
4008 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
4010 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
4012 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
4013 [David MacKenzie <djm pix.net>]
4015 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
4016 [David MacKenzie <djm pix.net>]
4018 *) Fix segfault and display error when SSLMutex file can not be
4019 created. [Adam Sussman <myddryn vishnu.vidya.com>]
4021 *) Add reference counting to mod_mem_cache cache objects to
4022 better manage removing objects from the cache.
4025 *) Change the verbage on the ScoreBoardFile in our default configs.
4026 Also change the default to be commented out (unspecified) so we
4027 get anonymous shared memory by default. [Aaron Bannert]
4029 *) Implement new ScoreBoardFile directive logic. This affects how
4030 we create the scoreboard's shared memory segment. If the directive
4031 is present, a name-based segment is created. If the directive is
4032 not present, first an anonymous segment is created, and if that
4033 fails, a name-based segment is created from a file of the name
4034 DEFAULT_SCOREBOARD. This gives third-party applications the
4035 ability to access our scoreboard. [Aaron Bannert]
4037 *) Allow mod_deflate to work with non-GET requests and properly send
4038 Content-Lengths. [Sander Striker <striker apache.org>]
4040 *) Fix ap_directory_merge() to correctly merge configs when there is
4041 no <Directory /> block. [Justin Erenkrantz, William Rowe]
4043 *) Remove spurious debug messsages that are normal under HTTP
4044 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
4046 *) Fix a bug in mod_cgid that would prevent proper shutdown death
4047 of the cgid process. [Aaron Bannert]
4049 *) Add signal handling back in to the worker MPM for the one_process
4050 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
4052 *) Performance: Reuse per-connection transaction pools in the
4053 worker MPM, rather than destroying and recreating them. [Brian Pane]
4055 *) Remove all signals from the worker MPM's child process. Instead,
4056 the parent uses the Pipe of Death for all communication with the
4057 child processes. [Ryan Bloom]
4059 Changes with Apache 2.0.32
4061 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
4062 default if the directive is not specified. This mirrors older
4063 behavior without changes to the httpd.conf. [William Rowe]
4065 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
4066 the service, mpm and logging code, and bugs in apr_file_open_stderr
4067 and apr_file_dup2 functions. Win2K/XP services have no handles
4068 associated for stdin/out/err, which caused unpredictable behavior
4069 in the prior release. [William Rowe, Bill Stoddard]
4071 *) Win32: simplify the Application Event Log messages, since there isn't
4072 likely to be 'more information in the error log' before an error log
4073 has been opened. [William Rowe]
4075 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
4076 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
4078 *) Win32: apache -k shutdown now behaves like apache -k stop.
4081 *) Fix prefork to not kill the parent if a child hits a resource shortage
4082 on accept(). [Greg Ames]
4084 *) Fix seg faults that occur when what should be the httpd request line
4085 starts with \r\n followed by garbage. [Greg Ames]
4087 *) Allow statically linked support binaries with the new
4088 --enable-static-support flag, and enable this behavior in
4089 the binbuild script. Also add a new --enable-static-htdbm
4090 flag. [Aaron Bannert]
4092 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
4093 do only one stat() call when generating the directory listings.
4096 *) Fix resolve_symlink to save the original symlink name if known.
4099 *) Be a bit more sane with regard to CanonicalNames. If the user has
4100 specified they want to use the CanonicalName, but they have not
4101 configured a port with the ServerName, then use the same port that
4102 the original request used. [Ryan Bloom and Ken Coar]
4104 *) In core_input_filter, check for an empty brigade after
4105 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
4106 client says it will post some data but we get FIN before any
4107 data arrives. [Jeff Trawick]
4109 *) Not being able to bind to the socket is a fatal error. We should
4110 print an error to the console, and return a non-zero status code.
4111 With these changes, all of the Unix MPMs do that correctly.
4114 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
4115 through to CGI scripts. PR 9163
4116 [Brian Reid <breid customlogic.com>,
4117 Zvi Har'El <rl math.technion.ac.il>]
4119 *) binbuild.sh: Make sure that we use the expat from our source
4120 tree so that there aren't any surprises on the target machine.
4123 *) mod_cgid: Add retry logic for when the daemon can't fork fast
4124 enough to keep up with new requests. Start using
4125 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
4126 when we can't talk to the daemon. [Jeff Trawick]
4128 *) apxs: LTFLAGS envvar can override default libtool options. Try
4129 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
4130 the covers. [Jeff Trawick]
4132 *) The Location: response header field, used for external
4133 redirect, *must* be an absoluteURI. The Redirect directive
4134 tested for that, but RedirectMatch didn't -- it would allow
4135 almost anything through. Now it will try to turn an abs_path
4136 into an absoluteURI, but it will correctly varf like Redirect
4137 if the final redirection target isn't an absoluteURI. [Ken Coar]
4139 Changes with Apache 2.0.31
4141 *) Create the scoreboard (in the parent) in a global pool context,
4142 so it survives graceful restarts. This fixes a SEGV during
4143 graceful restarts. [Aaron Bannert]
4145 *) Add a timeout option to the proxy code 'ProxyTimeout'
4148 *) FTP directory listings are now always retrieved in ASCII mode.
4149 The FTP proxy properly escapes URI's and HTML in the generated
4150 listing, and escapes the path components when talking to the FTP
4151 server. It is now possible to browse the root directory by using
4152 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
4153 Also, the last path component may contain wildcard characters
4154 '*' and '?', and if they do, a directory listing is created instead
4155 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
4158 *) Added single-listener unserialized accept support to the
4159 worker MPM [Brian Pane]
4161 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
4162 the incoming host header through to the proxied server
4163 [Geoff <g.russell ieee.org>]
4165 *) New Directive Option for ProxyPass. It now can block a location
4166 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
4168 *) Don't let the default handler try to serve a raw directory. At
4169 best you get gibberish. Much worse things can happen depending
4170 on the OS. [Jeff Trawick]
4172 *) Change the pre_config hook to return a value. Modules can now emit
4173 an error message and then cause the server to quit gracefully during
4174 startup. This required a bump to the MMN. [Aaron Bannert]
4176 *) Fix some unix socket descriptor leaks in the handler side of
4177 mod_cgid (the part that runs in the server process). Whack a
4178 silly "close(-1)" in the handler too. [Jeff Trawick]
4180 *) Change the pre_mpm hook to return a value, so that scoreboard
4181 init errors percolate up to code that knows how to exit
4182 cleanly. This required a bump to the MMN. [Jeff Trawick]
4184 *) Add the socket back to the conn_rec and remove the create_connection
4185 hook. The create_connection hook had a design flaw that did not
4186 allow creating connections based on vhost info. [Bill Stoddard]
4188 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
4189 Resolves the common case of using negotation to resolve the request
4190 /script/foo for /script.cgi/foo. [William Rowe]
4192 *) Added new functions ap_add_(input|output)_filter_handle to
4193 allow modules to bypass the usual filter name lookup when
4194 adding hard-coded filters to a request [Brian Pane]
4196 *) caching should now work on subrequests (still very experimental)
4199 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
4201 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
4204 *) Refactor ap_rgetline so that it does not use an internal brigade.
4205 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
4207 *) Remove mod_auth_db. [Justin Erenkrantz]
4209 *) Do not install unnecessary pcre headers like config.h and internal.h.
4210 [Joe Orton <joe manyfish.co.uk>]
4212 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
4213 (as it does for a normal request). quick_handled sub-requests now work
4214 in mod-include [Ian Holsman]
4216 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
4217 'CONTENT' one, as it needs to run AFTER all content headers
4219 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
4222 *) Split out blocking from the mode in the input filters.
4225 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
4227 *) Cause Win32 to capture all child-worker process errors in
4228 Apache to the main server error log, until the child can
4229 open its own error logs. [William Rowe]
4231 *) HPUX 11.*: Do not kill the child process when accept()
4232 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
4233 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
4235 *) Fix a problem in the parsing of the <Proxy foo> directive.
4238 *) rewrite of mod_ssl input filter for better performance and less
4239 memory usage [Doug MacEachern]
4241 *) allow quick_handler to be run on subrequests. [Ian Holsman]
4243 *) mod_dav now asks its provider to place content directly into the
4244 filter stack when handling a GET request. The mod_dav/provider
4245 API has changed, so providers need to be updated. [Greg Stein]
4247 *) Clear the output socket descriptor in unixd_accept() to make sure
4248 we don't supply a bogus socket to the caller if the accept fails.
4249 This caused problems with the worker MPM, which tried to process
4250 the returned socket if it was non-NULL. [Brian Pane]
4252 *) Move a check for an empty brigade to the start of core input filter
4253 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
4255 *) Add FileETag directive to allow configurable control of what
4256 data are used to form ETag values for file-based URIs. MMN
4257 bumped to 20020111 because of fields added to the end of
4258 the core_dir_config structure. [Ken Coar]
4260 *) Fix a segfault in mod_rewrite's logging code caused by passing the
4261 wrong config to ap_get_remote_host(). [Jeff Trawick]
4263 *) Allow mod_cgid to work from a binary distribution install by
4264 using 755 for the permissions on the log directory instead of
4267 *) Fixed a segfault that happened during graceful shutdown (or when
4268 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
4270 *) Split all Win32 modules [excluding the core components mod_core,
4271 mod_so, mod_win32 and the winnt mpm] into individual loadable
4272 modules, so the administrator may individually disable the former
4273 compiled-in modules by simply commenting out their LoadModule
4274 directives. [William Rowe]
4276 *) Saved Win32 module authors and porters many future headaches, by
4277 duplicating the appropriate .h files such as os.h into the include
4278 directory, including in the build tree. [William Rowe]
4280 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
4281 Use SSL functions/macros instead of directly dereferencing SSL
4282 structures wherever possible.
4283 Add type-casts for the cases where functions return a generic pointer.
4284 Add $SSL/include to configure search path.
4285 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4287 *) Moved several pointers out of the shared Scoreboard so it is
4288 more portable, and will present the vhost name across server
4289 generation restarts. [William Rowe]
4291 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
4294 Changes with Apache 2.0.30
4296 *) Fix the main bug for FreeBSD and threaded MPM's. There are
4297 still issues (see STATUS) but at least the server will now
4298 run without crashing the machine.
4299 [David Reid, Aaron Bannert, Justin Erenkrantz]
4301 *) Fix a typo in mod_deflate's m4 config section.
4302 [albert chin <china thewrittenword.com>]
4304 *) Fix a couple of mod_proxy problems forwarding HTTP connections
4305 and handling CONNECT:
4306 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
4307 (2) Proxy failed to connect when the first IP address returned by
4308 the resolver was unreachable but a secondary IP address was.
4311 *) Fix the module identifer as shown in the docs for various core
4312 modules (e.g., the identifer for mod_log_config was previously
4313 listed as config_log_module). PR #9338
4314 [James Watson <ap2bug sowega.org>]
4316 *) Fix LimitRequestBody directive by placing it in the HTTP
4317 filter. [Justin Erenkrantz]
4319 *) Fix mod_proxy seg fault when the proxied server returns
4320 an HTTP/0.9 response or a bogus status line.
4323 *) Prevent mod_proxy from truncating one character off the
4324 end of the status line returned from the proxied server.
4325 [Adam Sussman, Bill Stoddard]
4327 *) Eliminate loop in ap_proxy_string_read().
4328 [Adam Sussman, Bill Stoddard]
4330 *) Provide $0..$9 results from mod_include regex parsing.
4333 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
4335 *) Introduced the ForceLanguagePriority directive, to prevent
4336 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
4337 when using Multiviews. [William Rowe]
4339 *) Fix a problem which prevented mod_cgid and suexec from working
4340 together reliably [Greg Ames]
4342 *) Remove the call to exit() from within mod_auth_digest's post_config
4343 phase. [Aaron Bannert]
4345 *) Fix a problem in mod_auth_digest that could potentially cause
4346 problems with initialized static data on a system that uses DSOs.
4349 *) Fix a segfault in the worker MPM that could happen during
4350 child process exits. [Brian Pane, Aaron Bannert]
4352 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
4354 *) Fix matching of vhosts by ip address so we find IPv4
4355 vhost address when target address is v4-mapped form of
4356 that address. [Jeff Trawick]
4358 *) More performance tweaks to the BNDM string-search algorithm
4359 used to find "<!--#" tokens in mod_include [Brian Pane]
4361 *) Miscellaneous small performance fixes: optimized away various
4362 string copy operations and removed large temp buffers from
4363 the stack [Brian Pane]
4365 *) Fixed startup segfault that occurred when a VirtualHost
4366 directive had a port but no address [Brian Pane]
4368 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
4370 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
4371 if oslevel < WINNT. This should fix several problems reported
4372 Against 2.0.28 on Windows 98 [Bill Stoddard]
4374 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
4375 to fail. [Bill Stoddard]
4377 *) Change core code to allow an MPM to set hard thread/server
4378 limits at startup. prefork, worker, and perchild MPMs now have
4379 directives to set these limits. [Jeff Trawick]
4381 *) Win32: The async AcceptEx() event should be autoreset upon
4382 successful completion of a wait (WaitForSingleObject). This
4383 eliminates a number of spurious
4384 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
4387 *) Move any load library path environment variables out of
4388 apachectl and into a separate environment variable file which
4389 can be more easily tailored by the admin. The environment
4390 variable file as built by Apache may have additional system-
4391 specific settings. For example, on OS/390 we tailor the heap
4392 settings to allow lots of threads. [Jeff Trawick]
4394 *) Use the new APR pool code to reduce pool-related lock
4395 contention in the worker MPM. [Sander Striker]
4397 *) The POD no longer assumes the child is listening on 127.0.0.1
4398 and now pulls the first hostname in the list of listeners to
4399 perform the dummy connect on. This fixes a bug when the user
4400 had configured the Listen directive for an IP other than
4401 127.0.0.1. This would result in undead children and error
4402 messages such as "Connection refused: connect to listener".
4405 *) The worker MPM now respects the LockFile setting, needed to
4406 avoid locking problems with NFS. [Jeff Trawick]
4408 *) Fix segfault when worker MPM receives SIGHUP.
4409 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
4411 *) Fix bug that could potentially prevent the perchild MPM from
4412 working with more than one vhost/uid. [Aaron Bannert]
4414 *) Change make install and apxs -i processing of DSO modules to
4415 perform special handling on platforms where libtool doesn't install
4416 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
4417 which prevented standard LoadModule statements from working.
4420 *) Whenever mod_so is enabled (not just when there are DSOs for
4421 our modules), do whatever special magic is required for compiling/
4422 loading third-party modules. This allows third-party DSOs to
4423 be used on an AIX build when there were no built-in modules
4424 built as DSOs. (This should help on OS/390 and BeOS as well.)
4427 *) Allow apxs to be used to build DSOs on AIX without requiring the
4428 user to hard-code the list of import files. (This should help
4429 on OS/390 and BeOS as well.) [Jeff Trawick]
4431 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
4432 PR 8563, 8919 [William Rowe]
4434 *) Get binary builds working when libapr and libaprutil are built
4437 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
4438 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
4439 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
4441 *) Fix the handling of SSI directives in which the ">" of the
4442 terminating "-->" is the last byte in a file [Brian Pane]
4444 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
4445 message that we had back in apache-1.3 and still have scattered
4446 throughout our docs. [Aaron Bannert]
4448 *) Prevent the Win32 port from continuing after encountering an
4449 error in the command line args to apache. [William Rowe]
4451 *) On a error in the proxy, make it write a line to the error log
4454 *) Various mod_ssl performance improvements [Doug MacEachern]
4456 Changes with Apache 2.0.29
4458 *) Add buffering in core_output_filter to ensure that long
4459 lists of small buckets don't cause small packet writes.
4460 [Brian Pane, Ryan Bloom]
4462 *) Fix the installation target to make sure that the manual is
4463 installed in the correct location.
4464 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
4465 Gomez Henri <hgomez slib.fr>]
4467 *) Fix the cmd command for mod_include. When we are processing
4468 a cmd command, we do not want to use the r->filename to set
4469 the command name. The command comes from the SSI tag. To do this,
4470 I added a variable to the function that builds the command line
4471 in mod_cgi. This allows the include_cmd function to specify
4472 the command line itself. [Ryan Bloom]
4474 *) Change open_logs hook to return a value, allowing you
4475 to flag a error while opening logs
4476 [Ian Holsman, Doug MacEachern]
4478 *) Change post_config hook to return a value, allowing you
4479 to flag a error post config
4480 [Ian Holsman, Jeff Trawick]
4482 *) Allow SUEXEC_BIN (the path to the suexec binary that is
4483 hard-coded into the server) to be specified to the configure
4484 script by the --with-suexec-bin parameter. [Aaron Bannert]
4486 *) Fix segv in worker MPM following accept on pipe-of-death
4489 *) Add mod_deflate to experimental.
4490 [Ian Holsman, Justin Erenkrantz]
4492 *) Bail out at configure time if an invalid MPM was specified.
4493 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4495 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
4496 configured [John Sterling <sterling covalent.net>]
4498 *) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>]
4500 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
4502 *) Optimization for the BNDM string-search function in
4503 mod_include. [Brian Pane]
4505 *) Fixed the behavior of the XBitHack directive.
4506 [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
4508 *) The threaded MPM for Unix has been removed. Use the worker
4509 MPM instead. [various]
4511 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
4512 in logging the error from a failed DNS lookup. [Jeff Trawick]
4514 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
4517 *) Get mod_cgid killed when a MPM exits due to a fatal error.
4520 *) Fix a file descriptor leak in mod_include. When we include a
4521 file, we use a sub-request, but we didn't destroy the sub-request
4522 immediately, instead we waited until the original request was
4523 done. This patch closes the sub-request as soon as the data is
4524 done being generated. [Brian Pane <bpane pacbell.net>]
4526 *) Allow modules that add sockets to the ap_listeners list to
4527 define the function that should be used to accept on that
4528 socket. Each MPM can define their own function to use for
4529 the accept function with the MPM_ACCEPT_FUNC macro. This
4530 also abstracts out all of the Unix accept error handling
4531 logic, which has become out of synch across Unix MPMs.
4534 *) Fix a bug which would cause the response headers to be omitted
4535 when sending a negotiated ErrorDocument because the required
4536 filters were attached to the wrong request_rec.
4537 [John Sterling <sterling covalent.net>]
4539 *) Remove commas from the end of the macros that define
4540 directives that are used by MPMs. Prior to this patch,
4541 you would use these macros without commas, which was unlike
4542 the macros for any other directives. Now, the caller provides
4543 the comma rather than the macro providing it. This makes
4544 the macros look more like the rest of the directives.
4545 [Ryan Bloom and Cliff Woolley]
4547 *) Add 'redirect-carefully' environment option to disable sending
4548 redirects under special circumstances. This is helpful for
4549 Microsoft's WebFolders when accessing a directory resource via
4550 DAV methods. [Justin Erenkrantz]
4552 *) Begin to abstract out the underlying transport layer.
4553 The first step is to remove the socket from the conn_rec,
4554 the server now lives in a context that is passed to the
4555 core's input and output filters. This forces us to be very
4556 careful when adding calls that use the socket directly,
4557 because the socket isn't available in most locations.
4560 *) Really reset the MaxClients value in worker and threaded
4561 when the configured value is not a multiple of the number
4562 of threads per child. We said we did previously but we
4563 forgot to. [Jeff Trawick]
4565 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
4567 *) If shared modules are requested and mod_so is not available,
4568 produce a fatal config-time error. [Justin Erenkrantz]
4570 *) Improve http2env's performance by cutting the work it has to
4571 do. [Brian Pane <bpane pacbell.net>]
4573 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
4574 [Brian Pane <bpane pacbell.net>]
4576 Changes with Apache 2.0.28
4578 *) Fix infinite loop in mod_cgid.c.
4579 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
4581 *) When no port is given in a "ServerName host" directive, the
4582 server_rec->port is now set to zero, not 80. That allows for
4583 run-time deduction of the correct server port (depending on
4584 SSL/plain, and depending also on the current setting of
4585 UseCanonicalName). This change makes redirections
4586 work, even with https:// connections. As in Apache-1.3, the
4587 connection's actual port number is never used, only the ServerName
4588 setting or the client's Host: setting. Documentation updated
4589 to reflect the change. [Martin Kraemer]
4591 *) Add a '%{note-name}e' argument to mod-headers, which works in
4592 the same way as mod_log_confg. [Ian Holsman]
4594 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
4595 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
4596 MPMs. [Cliff Woolley]
4598 *) Introduce htdbm, a user management utility for db/dbm authorization
4599 databases. [Mladen Turk <mturk mappingsoft.com>]
4601 *) Optimize usage of strlen and strcat in ap_directory_walk.
4602 [Brian Pane <bpane pacbell.net>]
4604 Changes with Apache 2.0.27
4606 *) Introduce an Apache mod_ssl initial configuration template
4607 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
4609 *) Fixed a memory leak in the getline parsing code that could
4610 be triggered by arbitrarily large header lines. Requests
4611 from the core input filter for single lines are now limited
4612 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
4614 *) Fix a truncation bug in how we print the port on the Via: header.
4615 The routine that prints the Via: header now takes a length for
4616 the port string. [Zvi Har'El <rl math.technion.ac.il>]
4618 *) Some syntax errors in mod_mime_magic's magic file can result
4619 in a 500 error, which previously was unlogged. Now we log the
4620 error. [Jeff Trawick]
4622 *) Add the support/checkgid helper app, which checks the run-time
4623 validity of group identifiers usable in the Group directive.
4626 *) Various --enable-so options have been fixed: --enable-so is
4627 treated as "static"; explicit --enable-so=shared issues an error;
4628 and explicit --enable-so fails with error on systems without
4629 APR_HAS_DSO. [Aaron Bannert]
4631 *) Fix a segfault in the core input filter when the client socket
4632 gets disconnected unexpectedly. [Cliff Woolley]
4634 *) Fix the reporting for child processes that die. This removes
4635 all of the non-portable W* macros from Apache.
4636 [Jeff Trawick and Ryan Bloom]
4638 *) Win32: Track and display "Parent Server Generation:" in
4639 mod_status output. The generation will be bumped at
4640 server graceful restart, when the child process exits
4641 by hitting MaxRequestsPerChild or if the child
4642 process exits abnormally. [Bill Stoddard]
4644 *) Win32: Fix problem where MaxRequestsPerChild directive was
4645 not being picked up in favor of the default. Enable
4646 the parent to start up a new child process immediately upon
4647 the old child starting shutdown.
4650 *) Fix some bungling of the remote port in rfc1413.c so that
4651 IdentityCheck retrieves the proper user id instead of failing
4652 and thus always returning "nobody."
4653 [Dick Streefland <Dick.Streefland xs4all.nl>]
4655 *) Introduced thread saftey for mod_rewrite's internal cache.
4656 [Brian Pane <bpane pacbell.net>]
4658 *) Simplified mod_env's directives to behave as most directives are
4659 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
4660 directive following that UnsetEnv within the same container.
4661 Also provides a runtime startup warning if a PassEnv configured
4662 environment value is undefined. [William Rowe]
4664 *) The worker MPM is now completely ported to APR's new lock API. It
4665 uses native APR types for thread mutexes, cross-process mutexes,
4666 and condition variables. [Aaron Bannert]
4668 *) Sync up documentation to remove all references to the now deprecated
4669 Port directive. [Justin Erenkrantz]
4671 *) Moved all ldap modules from the core to httpd-ldap sub-project
4674 *) Exit when we can't listen on any of the configured ports. This
4675 is the same behavior as 1.3, and it avoids having the MPMs to
4676 deal with bogus ap_listen_rec structures. [Jeff Trawick]
4678 *) Cleanup the proxy code that creates a request to the origin
4679 server. This change adds an optional hook, which allows modules
4680 to gain control while the request is created if the proxy module
4681 is loaded. The purpose of this hook is to allow modules to add
4682 input and/or output filters to the request to the origin. While
4683 I was at it, I made the core use this hook, so that proxy request
4684 creation uses some of the code from the core. This can still be
4685 greatly improved, but this is a good start. [Ryan Bloom]
4687 Changes with Apache 2.0.26
4689 *) Port the MaxClients changes from the worker MPM to the threaded
4692 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
4693 with the new input filtering system. [Justin Erenkrantz]
4695 *) Introduce the MultiviewsMatch directive, to allow the operator
4696 to be flexible in recognizing Handlers and Filters filename
4697 extensions as part of the Multiviews matching logic, strict with
4698 MultiviewsMatch NegotiatedOnly to accept only filename extentions
4699 that designate negotiated parameters, (content type, charset, etc.)
4700 or MultiviewsAll for the 1.3 behavior of matching any files, even
4701 if they have unregistered extensions. [William Rowe]
4703 *) Fixed the configure script to add a LoadModule directive to
4704 the default httpd.conf for any module that was compiled
4705 as a DSO. [Aaron Bannert <aaron clove.org>]
4707 *) rewrite mod_ssl input filtering to work with the new input filtering
4708 system. [Justin Erenkrantz]
4710 *) prefork: Don't segfault when we are able to listen on some but
4711 not all of the configured ports. [Jeff Trawick]
4713 *) Build mod_so even if no core modules are built shared.
4714 [Aaron Bannert <aaron clove.org>]
4716 *) Introduce ap_directory_walk rewrite (with further optimizations
4717 required) to adapt to the ap_process_request_internal() changes.
4718 Optimized so subrequests and redirects now reuse previous section
4719 merges, until we mismatch with the original directory_walk, and
4720 precomputed r->finfo results will cause directory_walk to skip
4721 the most expensive phases of the function. [William Rowe]
4723 *) Allow ApacheMonitor to connect to and control Apache on other
4724 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
4726 *) Remove the Port directive. In it's place, the Listen directive
4727 is now a required directive, which tells Apache what port to
4728 listen on. The ServerName directive has also been extended
4729 to accept an optional port. If the port is specified to the
4730 ServerName, the server will report that port whenever it
4731 reports the port that it is listening on. This change was
4732 made to ease configuration errors that stem from having a Port
4733 directive, and a Listen directive. In that situation, the server
4734 would only listen to the port specified by the Listen command,
4735 which caused a lot of confusion to users. [Ryan Bloom]
4737 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
4738 build, as loadable modules. [William Rowe]
4740 *) Fix --enable-mods-shared processing. If most is specified,
4741 then all modules that can be compiled as shared modules are.
4742 [Aaron Bannert <aaron clove.org>]
4744 *) Update the mime.types file to map video/vnd.mpegurl to mxu
4745 and add commonly used audio/x-mpegurl for m3u extensions.
4746 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
4748 *) Eliminate the depreciated r->content_language, in favor of the array
4749 r->content_languages introduced many years ago. Module authors must
4750 substantially overhaul their modules, so this needs to be upgraded
4751 if the module still relied on backwards-brokeness. [William Rowe]
4753 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
4756 *) Rewrite the input filtering mechanisms to consolidate and reorganize
4757 code. In short, core_input_filter does something now and
4758 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
4760 *) Update the Win32 build to re-absorb mod_proxy and family.
4763 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
4764 current SDK.) [William Rowe]
4766 *) Some style changes to the code that does ProxyErrorOverride. Fixed
4767 config merge behaviour. [Graham Leggett]
4769 *) Allow support programs to be compiled against a static version
4770 of libapr. This allows the smaller support programs to be
4771 relocated. [Aaron Bannert <aaron clove.org>]
4773 *) Update the mime.types file to the registered media types as
4774 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
4776 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
4777 number of clients that can connect at the same time, instead of
4778 specifying the maximum number of child processes.
4779 [Aaron Bannert <aaron clove.org>]
4781 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
4782 be consistent with 1.3. [Justin Erenkrantz]
4784 *) Cache apr_explode_localtime() value for 15 seconds.
4785 [Brian Pane <bpane pacbell.net>]
4787 *) Fix mod_include to not return ETag or Last-Modified headers.
4788 [Ian Holsman <ianh cnet.com>]
4790 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
4792 *) Eliminate the wasteful run-time conversion of method names from strings
4793 to numbers in places where the methods are known at compile time.
4794 [Brian Pane <bpane pacbell.net>]
4796 *) Turn the worker MPM's queue into a LIFO. This may
4797 improve cache-hit performance under some conditions.
4798 [Aaron Bannert <aaron clove.org>]
4800 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
4801 support it. [Justin Erenkrantz]
4803 *) Cleanup the worker MPM. We no longer re-use transaction
4804 pools. This incurs less overhead than shuffling the pools
4805 around so that they can be re-used. Remove one of the
4806 queue's condition variables. We just redefined the API to
4807 state that you can't try to add more stuff than you allocated
4808 segments for. [Aaron Bannert <aaron clove.org>]
4810 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
4812 *) Fixed persistent connections when a request contains a body.
4815 *) mod_dav uses a new API to speak to the backend provider for dead
4816 property management. [Greg Stein]
4818 *) Remove the Win32 script-processing exception from mod_cgi, and
4819 roll build_command_line/build_argv_list into a unified, overrideable
4820 ap_cgi_build_command optional function. [William Rowe]
4822 *) Rewrite find_start_sequence to use a better search algorithm
4823 to find the start tag. [Justin Erenkrantz]
4825 *) Fix a seg fault in mod_include. When we are generating an
4826 internal redirect, we must set r->uri to "", not a bogus
4827 string, and not NULL. [Ryan Bloom]
4829 *) Optimized location_walk, so subrequests, redirects and second passes
4830 now reuse previous section merges on a <Location > by <Location >
4831 basis, until we mismatch with the original location_walk.
4834 *) Back out the 1.45 change to util_script.c. This change made
4835 us set the environment variable REQUEST_URI to the redirected
4836 URI, instead of the originally requested URI.
4837 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4839 *) Make mod_include do lazy evaluation of potentially expensive to
4840 compute variables. [Brian Pane <bpane pacbell.net>]
4842 *) Fix logging of bytes sent for HEAD requests. %b and %B should
4843 log either - or 0, before this patch, they were both logging
4844 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
4846 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
4847 than per character. [Brian Pane <bpane pacbell.net>]
4849 *) Normalize the primary request, redirects and sub-requests to
4850 run the same ap_process_request_internal for consistency in
4851 robustness, behavior and security. [William Rowe]
4853 *) Fix a segfault with mod_include when r->path_info is not set
4854 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
4856 *) Add -X functionality back. This indicates to all MPMs and any other
4857 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
4859 *) Some initial support for the cygwin platform [prefork only].
4860 This is not to be confused with support for the WinNT/Win32
4861 platform, which is the recommended configuration for native
4862 Win32 users. The cygwin platform support is recommended for
4863 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
4865 *) Changed syntax of Set{Input|Output}Filter. The list of filters
4866 must be semicolon delimited (if more than one filter is given.)
4867 The Set{Input|Output}Filter directive now overrides a parent
4868 container's directive (e.g. SetInputFilter in <Directory /web/foo>
4869 will override any SetInputFilter directive in <Directory /web>.)
4870 This new syntax is more consistent with Add{Input|Output}Filter
4871 directives defined in mod_mime. Also cures a bug in prior releases
4872 where the Set{Input|Output}Filter directive would corrupt the
4873 global configuration if the multiple directives were nested.
4876 *) Cured what's ailed mime for quite some time. If an AddSomething
4877 was given in the configuration (Language, Charset, Handler or
4878 Encoding) Apache would set the content type as given by AddType,
4879 but refused to check the mime.types file if AddType wasn't given
4880 for that specific extension. Setting the AddHandler for .html
4881 without setting the AddType text/html html would cause Apache to
4882 use the default content type. [William Rowe]
4884 *) Added some bulletproofing to memory allocation in the LDAP cache
4885 code. [Graham Leggett]
4887 Changes with Apache 2.0.25
4889 *) Move the installed /manual directory out of the /htdocs/ tree, so
4890 that it can be kept more independently from the remaining document
4891 root. The "Alias /manual ..." already allowed for easy projection
4892 into existing private document trees. [Martin Kraemer]
4894 *) Add specified user attributes to the environment when using
4895 mod_auth_ldap. This allows you to use mod_include to embed specified
4896 user attributes in a page like so:
4897 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
4900 *) Fix a performance problem with the worker MPM. We now create
4901 transaction pools once, and re-use them for each connection.
4902 [Aaron Bannert <aaron clove.org>]
4904 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
4905 of a 'handler' or 'filter', so that any filename extension that does
4906 not contribute to the negotiated metadata can't be served without
4907 an explicit request. E.g., if the .Z extension is associated with
4908 an unzip filter, the user request somefile.Z.html, mod_negotiation
4909 won't serve it. It can serve somefile.Z.html when somefile.Z is
4910 requested, since the .Z extension is explictly requested, if the
4911 .html extension is associated with ContentType text/html.
4914 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
4915 and corresponding AddOutputFilter syntax, to insert one or more
4916 filters by mod_mime filename extension processing.
4919 *) Fix a growing connection pool in core_output_filter() for
4920 keepalive requests. [Jeff Trawick]
4922 *) Moved split_and_pass_pretag_buckets back to being a
4923 macro at Ryans's request. Removed the return from it
4924 by setting and returning a return code instead. Updated
4925 the code to check the return code from the macro and
4926 do the right thing. [Paul J. Reder]
4928 *) Fix a segfault when a numeric value was received for Host:.
4931 *) Add a function ap_remove_input_filter. This is to match
4932 up with ap_remove_output_filter. [Ryan Bloom]
4934 *) Clean up location_walk, so that this step performs a minimum
4935 amount of redundant effort (it must be run twice, but it will no
4936 longer reparse all <Location > blocks when the request uri
4937 hadn't changed.) [William Rowe]
4939 *) Eliminate proxy: (and all other 'special') processing from the
4940 ap_directory_walk() phase. Modules that want to use special
4941 walk logic should refer to the mod_proxy map_to_location example,
4942 with it's proxy_walk and proxysection implementation. This makes
4943 either directory_walk flavor much more legible, since that phase
4944 only runs against real <Directory > blocks.
4947 *) SECURITY: Fix a security problem in mod_include which would allow
4948 an SSI document to be passed to the client unparsed.
4949 [Cliff Woolley, Brian Pane]
4951 *) Introduce the map_to_storage hook, which allows modules to bypass
4952 the directory_walk and file_walk for non-file requests. TRACE
4953 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
4954 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
4957 *) Add the ability for mod_include to add the INCLUDES filter
4958 if the file is configured for the server-parsed handler.
4959 This makes the configuration for .shtml files much easier
4960 to understand, and allows mod_include to honor Apache 1.3
4961 config files. Based on Doug MacEachern's patch to PHP
4962 to do the same thing. [Ryan Bloom]
4964 *) force OpenSSL to ignore process local-caching and to always
4965 get/set/delete sessions using mod_ssl's callbacks
4966 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
4967 Geoff Thorpe <geoff geoffthorpe.net>]
4969 *) Make the worker MPM shutdown and restart cleanly. This also
4970 cleans up some race conditions, and gets the worker using
4971 pools more cleanly. [Aaron Bannert <aaron clove.org>]
4973 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
4975 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4977 *) Fix for mod_include. Ryan's patch to check error
4978 codes put a return in the wrong place. Also, the
4979 include handler return code wasn't being checked.
4980 I don't like macros with returns, so I converted
4981 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
4982 [Paul J. Reder <rederpj raleigh.ibm.com>]
4984 *) fix segv in mod_mime if no AddTypes are configured
4985 [John Sterling <sterling covalent.net>]
4987 *) Enable ssl client authentication at SSL_accept time
4988 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4990 *) Fix a segfault in mod_include when the original request has no
4991 associated filename (e.g., we're filtering the error document for
4992 a bad URI). [Jeff Trawick]
4994 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
4996 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
4997 of httpd is started and shuts down due to socket conflict. Moving the
4998 call to ap_log_pid solves the problem.
5000 *) Changed the late-1.3 log_config substitution %c to %X, to log the
5001 status of the closed connection, as it conflicts with the far more
5002 common, historical ssl logging directive %...{var}c. [William Rowe]
5004 *) Added the common error/ tree to the build/install targets
5005 (similar to the common icons/ tree) for the multi-language error
5006 messages that Lars committed earlier. [William Rowe]
5008 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
5010 *) Added a default commented-out mod_ldap and mod_auth_ldap
5011 configuration to httpd-std.conf and httpd-win.conf
5014 *) Added documentation for mod_ldap and mod_auth_ldap.
5017 *) Enabled negative caching on attribute comparisons in the LDAP cache.
5018 Fixed a problem where the default cache TTL was set in milliseconds
5019 not microseconds causing the cache to time out almost immediately.
5022 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
5023 module code to follow APR. [Graham Leggett]
5025 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
5026 cleaned up when the connection pool pool is cleaned up.
5029 *) Fix a minor issue with Jeff Trawick's mod_include
5030 patch. Without this patch, the code will just allocate
5031 more bytes in get_combined_directive than are needed.
5034 *) Added the LDAP authentication module mod_auth_ldap.
5035 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
5037 *) Added the LDAP cache and connection pooling module mod_ldap.
5038 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
5040 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
5041 by allowing a module to disable itself if its prerequisites are not
5042 met. [Justin Erenkrantz]
5044 Changes with Apache 2.0.24
5046 *) Fix a couple of issues in mod_include when the tag appeared at
5047 offsets near 8192 in the file being parsed. [Jeff Trawick]
5049 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
5050 reached. [Jeff Trawick]
5052 *) Numerous improvements to the Win32 build system. Introduced command line
5053 builds without requiring .mak files for MSVC 6.0 and later versions.
5054 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
5057 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
5058 reporting of uninstalled services and other error conditions, and changed the
5059 default service name to Apache2. [William Rowe]
5061 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
5062 compatibility with existing Apache 1.3 Win32 Apache management utilites.
5063 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
5065 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
5066 [William Rowe, Greg Ames]
5068 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
5069 and RemoveCharset directives. [William Rowe]
5071 *) The Unix MPMs other than perchild now allow child server
5072 processes to use the accept mutex when starting as root and
5073 using SysV sems for the accept mutex. Previously, this
5074 combination would lead to fatal errors in the child server
5075 processes. perchild can't use SysV sems because of security
5076 issues. [Jeff Trawick, Greg Ames]
5078 *) Added Win32 revision stamp resources to all http binaries
5079 (including modules/ and support/ tools.) PR7322 [William Rowe]
5081 *) Fix ap_rvprintf to support more than 4K of data at one time.
5082 [Cody Sherr <csherr covalent.net>]
5084 *) We have always used the obsolete/deprecated Netscape syntax
5085 for our tracking cookies; now the CookieStyle directive
5086 allows the Webmaster to choose the Netscape, RFC2109, or
5087 RFC2965 format. The new CookieDomain directive allows the
5088 setting of the cookie's Domain= attribute, too. PR #s 5006,
5089 5023, 5920, 6140 [Ken Coar]
5091 *) Tweak server/Makefile so that the rules for generating exports.c
5092 are compatible with make utilities which don't expand wildcards
5093 in a dependency list (e.g., OS/390 make, certain levels of GNU
5094 make). [Jeff Trawick]
5096 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
5098 *) Begin to sanitize the MPM configuration directives. Now, all
5099 MPMs use the same functions for all common MPM directives. This
5100 should make it easier to catch all bugs in these directives once.
5101 [Cody Sherr <csherr covalent.net>]
5103 *) Close a major resource leak. Every time we had issued a
5104 graceful restart, we leaked a socket descriptor.
5107 *) Fix a problem with the new method code. We need to cast
5108 the 1 to an apr_int64_t or it will be treated as a 32-bit
5109 integer, and it will wrap after being shifted 32 times.
5110 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
5112 *) Fix a bug in mod_expires. Previous to this patch, if you
5113 told mod_expires to add 604800 seconds to the last-modified
5114 time, it actually added 604800 usec's to the last-modified time,
5115 so that when looking at the response it looked like nothing
5116 had been done. The root of the problem was that we always compute
5117 time in usec's, but we ask users to input sec's. This means we
5118 need to convert to usec's before using those values.
5121 *) The worker MPM now handles shutdown and restart requests. It
5122 definitely isn't perfect, but we do stop the servers correctly.
5123 The biggest problem right now is that SIGHUP causes the server to
5124 just die. [Ryan Bloom]
5126 Changes with Apache 2.0.23
5128 *) Use the prefork MPM by default on Unix. [various]
5130 *) Added a systray icon monitor application for Win32.
5131 [Mladen Turk <mturk mappingsoft.com>]
5133 *) mod_rewrite: Fix the line ending on some non-Unix systems for
5134 messages written to the rewrite log.
5135 [Richard Labennett <rlabenn us.ibm.com>]
5137 *) All mod_autoindex query parsing is now quietly quashed with the
5138 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
5139 still drops the column sort <a href>'s for the column headers, but
5140 IgnoreClient is required to ignore these Query options entirely.
5143 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
5144 to allow the client to select plain, FancyIndexing or HTMLTable
5145 formatting, V=[0|1] to inhibit or enable version sorting, and
5146 P=pattern to return only specific files. The old Query Arguments
5147 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
5148 as before), and O=A|D for ordering ascending or descending.
5151 *) Fixed an error in mod_include's directive parsing routines which
5152 caused #if, #elif, and #else expressions containing backslashes
5153 to be improperly evaluated. [Cliff Woolley]
5155 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
5156 drop the icon column, SuppressRules to drop the <hr> elements,
5157 and HTMLTable to create rudimentary HTML table listings (implies
5158 FancyIndexing). [William Rowe]
5160 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
5161 from Apache 1.3.15. This is needed for two reasons, first, given
5162 multiple machines within a server farm, ETags and Last-Modified
5163 stamps won't correspond from machine to machine, and second, many
5164 Unixes don't capture changes to the date or time stamp of existing
5165 files, since these don't modify the dirent itself. [William Rowe]
5167 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
5168 and DirectoryWidth options from Apache 1.3.10.
5169 [William Rowe, Ken Coar]
5171 *) Eliminated FancyIndexing directive, deprecated early in Apache
5172 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
5174 *) mod_autoindex now excludes any file names that would result in
5175 an error, other than a success or redirect. Also optimized
5176 the parent directory, always included except in the URI '/'.
5179 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
5180 negotiated index pages, and prevent the server from defaulting
5181 to an autoindex of the directory. mod_negotiation will now die
5182 with a 500 Internal Error if it could match some filenames
5183 (e.g. for mod_dir) but none can be served. mod_negotation now
5184 refuses to serve any file with an extention that mod_mime doesn't
5185 recognize, and wasn't part of the request. [William Rowe]
5187 *) Eliminate mod_cgi's handling of .exe files without the .exe file
5188 extension. This is already handled by multiviews, if the admin
5189 wishes to AddHandler .exe or define a content type handler and
5190 associate .exe files with that content type. Multiviews must be
5191 enabled to allow these to be served. [William Rowe]
5193 *) Speed up the server's response to a spike in incoming workload
5194 or restarts by assigning empty scoreboard slots to new processes
5195 when they are available. [Greg Ames]
5197 *) Add a handler to mod_includes.c. This handler is designed to
5198 implement the XbitHack directive. This can't be done with a
5199 fixup, because we need to check the content-type, which is
5200 only available in the handler phase. [Ryan Bloom]
5202 *) Make the includes filter check return codes from filters lower in
5203 the filter chain. If a lower level filter returns an error, then
5204 the request needs to stop immediately. This allows mod_include to
5205 stop parsing data once a lower filter recognizes an error.
5208 *) Add the ability to extend the methods that Apache understands
5209 and have those methods <limit>able in the httpd.conf. It uses
5210 the same bit mask/shifted offset as the original HTTP methods
5211 such as M_GET or M_POST, but expands the total bits from an int to
5212 an ap_int64_t to handle more bits for new request methods than
5213 an int provides. [Cody Sherr <csherr covalent.net>]
5215 *) Fix broken mod_mime behavior in merging its arguments. Possible
5216 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
5218 *) Solve many mod_ssl porting issues (too many to detail) with
5219 help from the whole team, but most notably [Ralf S. Engelschall,
5220 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
5221 Doug MacEachern, William Rowe, Cliff Woolley]
5223 *) More stall fixes for the threaded & worker mpm's.
5224 Make mod_status output more accurate. Don't
5225 count workers in processes which aren't actively
5226 serving requests. [Greg Ames]
5228 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
5230 *) Add a single listener/multiple worker MPM. This MPM is
5231 definately not fully correct, but it allows us to solve many
5232 of the problems that exist in the threaded MPM. This is a
5233 modified version of the threaded MPM. [Ryan Bloom]
5235 *) Improve content generation throughout Apache, providing closer
5236 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
5237 Transitional specifications. [William Rowe]
5239 Changes with Apache 2.0.22
5241 *) Fix a problem where the threaded MPM stalls after restarts or
5242 segfaults. Also prevent multiple active processes from using
5243 the same scoreboard slot. [Greg Ames]
5245 *) Apache/Win32 now fills in the service description with Apache's
5246 server version string, including loaded and advertised modules.
5249 *) Improved support for the Win32 build, to recover gracefully from
5250 missing apr or apr-util directories or the awk interpreter,
5251 create the proper cgi-bin examples, including a test-cgi.bat, and
5252 fix the perl shebang line for printenv.pl, when installing from
5253 the build environment. [William Rowe]
5255 *) Fix a segfault in threaded.c caused by passing uninitialized
5256 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
5258 *) Use new APR number conversion functions to reduce CPU consumption
5259 when setting the content length, and in mod_log_config.
5262 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
5263 where HEAD response headers were being repeated twice for
5264 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
5265 problem in the http_header filter was exposed by the recent rewrite
5266 of the content_length filter. [Taketo Kabe, Bill Stoddard]
5268 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
5269 restarts. A garbage pointer to a vhost's server_rec from the
5270 previous generation was being left around under certain
5271 conditions. [Greg Ames]
5273 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
5274 used to appear as '(none', without the closing paren.
5275 [Günter Knauf <eflash gmx.net>]
5277 *) Improve the exports generating awk script. In the past, we had
5278 work around problems in the awk script by avoiding some #if and
5279 #ifdefs. This has bitten us many times in generating the exports.c
5280 file. This improvement allows corrects the header file parsing.
5281 [Sander Striker <striker apache.org>]
5283 Changes with Apache 2.0.21
5285 *) Resolve the Win32 htpasswd bug, where a file that existed would be
5286 overwritten, regardless of the -c flag.
5287 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
5289 *) Introduce connection sub-pools into ab. Truncating the lifetime
5290 of these allocations means that ab no longer perpetually grows
5291 its working set, running out of memory on large request attempts.
5294 *) Make scoreboard creation a hook. This allows management
5295 modules to have access to the scoreboard at the time that it is
5296 created, and at every restart request.
5297 [Cody Sherr <csherr covalent.net>]
5299 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
5300 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
5301 daemon index actually used in the scoreboard. I also
5302 updated the pertinent calls. [Paul J. Reder]
5304 *) Win32: Prevent listening sockets from being inherited by
5305 the Apache child process, CGI scripts, rotatelog process
5306 etc. If the Apache child process segfaults, any processes
5307 that the child started are not reaped. Prior to this fix,
5308 these processes inherited the listening sockets which sometimes
5309 prevented the restarted Apache child process from accepting
5310 connections (ie, the server would hang).
5313 *) Provide vhost and request strings when ExtendedStatus is on.
5316 *) Fix some issues with the pod and prefork: check the pod *after*
5317 processing a connection so that a server processing a time-
5318 consuming request bails out as soon as practical; when the
5319 parent process wakes up a server process via connect(), use an
5320 APR timeout on the connect() so that we don't hang for a long
5321 time if there aren't server processes around to do accept().
5322 [Jeff Trawick, Greg Ames]
5324 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
5325 spends a lot of time in apr_table_get calls. Using the default
5326 httpd.conf, the tables for languages and charsets are somewhat
5327 large, so the time spent scanning them on each request is
5328 significant. Replacing the tables with hash tables provides
5329 a nice speedup. [Brian Pane <bpane pacbell.net>]
5331 *) Add two functions to allow modules to access random parts of the
5332 scoreboard. This allows modules compiled for one MPM to access the
5333 scoreboard, even if it the server was compiled for another MPM.
5334 [Harrie Hazewinkel <harrie covalent.net>]
5336 Changes with Apache 2.0.20
5338 *) Fix problem in content-length filter where the filter would
5339 buffer all the output from a CGI before sending any bytes
5340 down the filter stack to the network. This problem would cause
5341 significant memory consumption if the CGIs generated
5342 lots of bytes. [Bill Stoddard]
5344 *) Get non-blocking CGI pipe reads working with the bucket brigades.
5347 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
5350 *) Fix a bug in the threaded MPM that would cause it to kill off all
5351 workers immediately after starting if the number of workers started
5352 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
5354 Changes with Apache 2.0.19
5356 *) Fix problem with threaded MPM. The problem was that if each child
5357 process was busy serving a single long-lived request and the server
5358 was sent a graceful restart signal, the server would stop serving
5359 requests. This would happen because each child process would wait to
5360 die until the last thread was done, and the parent wouldn't spawn any
5361 new children until a process died. Now, the parent looks at the fact
5362 that the children are dying gracefully, and starts new children.
5363 Those new children only start enough threads to compliment the number
5364 of threads in the other child process that shares the same spot in
5365 the scoreboard. In this way, we make sure to never go over
5366 MaxClients. [Ryan Bloom]
5368 *) modified mod_negotiation and mod_autoindex to speed up by almost a
5369 factor of two on apr_dir_read()-enhanced platforms, such as Win32
5370 and OS2, by calling ap_sub_request_lookup_dirent() with the results
5371 already provided by apr_dir_read(). [William Rowe]
5373 *) mod_file_cache is now more robust to filtering and serves requests
5374 slightly more efficiently. [Cliff Woolley]
5376 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
5377 Module was calling ap_rwrite() followed by ap_rflush() but the
5378 served content was not being displayed in the browser. Inspection
5379 of the output stream revealed that the first data chunk was
5380 missing the trailing CRLF required by the RFC. [Bill Stoddard]
5382 *) apxs no longer generates ap_send_http_header() in the example handler
5384 *) Fix an ab problem which could cause a divide-by-zero exception
5385 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
5386 [Ian Holsman <ianh cnet.com>]
5388 *) Solve case-insensitive platforms' confusion about negotiated
5389 filenames, allowing files of differnt case to match in choosing
5390 the document to serve. [William Rowe]
5392 *) Fix brokenness when ThreadsPerChild is higher than the built-in
5393 limit. We left ap_threads_per_child at the higher value which
5394 led to segfaults when doing certain scoreboard operations.
5397 *) Fix seg faults and/or missing output from mod_include. The
5398 default_handler was using the subrequest pool for files and
5399 MMAPs, even though the associated APR structures typically
5400 live longer than the subrequest. [Greg Ames]
5402 *) Extend mod_setenvif to support specifying regular expressions
5403 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
5404 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
5405 will cause HAVE_TS to be set if any of the request headers begins
5406 with "TS" and has a value that begins with any character in the
5407 set [a-z]. [Bill Stoddard]
5409 *) httpd children now re-bind themselves to a random CPU on
5410 multiprocessor systems on AIX via bindprocessor() in 2.0.
5411 [Victor J. Orlikowski]
5413 *) Fix htdigest. It would go into a loop in getline when adding
5414 a second user. [Bill Stoddard]
5416 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
5418 *) Automatically generate httpd.exp for AIX.
5419 DSOs now work again on AIX in 2.0
5420 [Victor J. Orlikowski]
5422 *) Add a new request hook, error_log. This phase allows modules
5423 to act on the error log string _after_ it has been written
5424 to the error log. The goal for this hook is to allow monitoring
5425 modules to send the error string to the monitoring agent.
5428 *) Modify mod_echo to make it use filters for input and output.
5429 [Ryan Morgan <rmorgan covalent.net>]
5431 *) Extend mod_headers to support conditional driven Header
5432 add, append and set. Use SetEnvIf to set an envar and conditionally
5433 add/append/set headers based on this envar thusly:
5435 SetEnvIf TSMyHeader value HAVE_TSMyHeader
5436 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
5438 If the request contains header "TSMyHeader: value" then header
5439 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
5442 *) Extend mod_headers to support using format specifiers on Header
5443 add, append and set header values. Two format specifiers are supported:
5445 %t - reports, in UTC microseconds since the epoch, when the
5446 request was received.
5448 %D - reports the time, in microseconds, between when the request was
5449 received and the response sent.
5452 Header add MyHeader "This request served in %D microseconds. %t"
5454 results in a header being added to the response that looks like this:
5456 MyHeader: This request served in D=5438 microseconds. t=991424704447256
5460 *) Fix reset_filter(). We need to be careful how we remove filters.
5461 If we set r->output_filters to NULL, we also have to reset the
5462 connection's filters. [John Sterling]
5464 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
5466 *) Add a check to ap_die() to make sure the filter stack is sane and
5467 contains the correct basic filters when an error occurs. This fixes
5468 a problem where headers are not being sent on error. [John Sterling]
5470 *) New Header directive 'echo' option. "Header echo regex" will
5471 cause any headers received on the request that match regex to be
5472 echoed to (included in) the response headers.
5475 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
5476 This prevented the inclusion of apr_compat.h. PR #7773
5477 [Oleg Broytmann <phd phd.pp.ru>]
5479 *) Moved util_uri to the apr-util library. This required a bunch of
5480 apr_name changes for the uri utility functions. [Justin Erenkrantz]
5482 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
5483 insert_filter phase so that other filters are not bypassed by default.
5486 *) Reimplement mod_headers as an output filter. mod_headers can now
5487 add custom headers to inbound requests using the RequestHeader directive
5488 and to responses using the same old Header directive. [Graham Leggett]
5490 Changes with Apache 2.0.18
5492 *) Fix command-line processing so that if a bad argument is specified
5493 Apache will exit. [Jeff Trawick]
5495 *) Change the make targets and rules to be consistent in all of the
5496 Apache-owned source trees. [Roy Fielding]
5498 *) Fix processing of the TRACE method. Previously we passed bogus
5499 parms to form_header_field() and it overlaid some vhost structures,
5500 resulting in a segfault in check_hostalias().
5501 [Greg Ames, Jeff Trawick]
5503 *) Win32: Add support for reliable piped logs. If the logging process
5504 goes down, Apache will automatically restart it. This function has
5505 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
5508 *) Do not start piped log processes during the config file
5509 preflight. This change also circumvents a problem on
5510 Windows where the rotatelog processes created during preflight
5511 was not getting cleaned up properly.
5514 *) add "Request Phase Participation" info to mod_info
5517 *) Make first phase changes to the scoreboard data structures in
5518 preparation for the rewriting of the scoreboard per my posted
5519 design notes. [Paul J. Reder]
5521 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
5522 and apr-util, allow it to be overridden by the configure command-line
5523 (default="--silent") and introduce LT_LDFLAGS to replace what we were
5524 formerly abusing as LTFLAGS. [Roy Fielding]
5526 *) Clean up the reporting of incorrect closing container tags.
5527 [Barrie Slaymaker <barries slaysys.com>]
5529 *) Simplify the configure process by moving all libtool stuff to APR
5530 and moving hints.m4 inline. [Roy Fielding]
5532 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
5533 of functions used by mod_proxy for export in the DLL
5534 [Ian Holsman <IanH cnet.com>]
5536 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
5537 request body from its stdin but no reqest body is being written to
5538 the cgi. [Jeff Trawick]
5540 *) mod_log_config: %c connection status incorrectly logged
5541 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
5544 *) Get mod_cern_meta working under Windows
5547 *) Create Files, and thus MMAPs, out of the request pool, not the
5548 connection pool. This solves a small resource leak that had us
5549 not closing files until a connection was closed. In order to do
5550 this, at the end of the core_output_filter, we loop through the
5551 brigade and convert any data we have into a single HEAP bucket
5552 that we know will survive clearing the request_rec.
5553 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
5556 *) Completely revamp configure so that it preserves the standard make
5557 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
5558 the configure additions to EXTRA_* variables. Also, allow the user
5559 to specify NOTEST_* values for all of the above, which eliminates the
5560 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
5561 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
5562 avoid pointless duplications. Fix the order in which flags are given
5563 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
5564 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
5565 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
5566 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
5568 *) Get mod_tls to compile/work better on Windows. PR #7612
5569 [Bernhard Schrenk <b.schrenk improx.com>]
5571 *) Fix shutdown/restart hangs in the threaded MPM.
5572 [Jeff Trawick, Greg Ames, Ryan Bloom]
5574 *) Removed the keptalive boolean from conn_rec because it is now only
5575 used by a single routine and can be replaced by a local variable.
5576 [Greg Stein, Ryan Bloom, Roy Fielding]
5578 *) Patch prefork to put enough of the signal processing back in so that
5579 signals are all handled properly now. The previous patch fixed the
5580 deadlock race condition, but broke the user directed signal handling.
5581 This fixes it to work the way it did before my previous prefork patch
5582 (primarily, SIGTERM is now working).
5584 *) Change how input filters decide how much data is returned to the
5585 higher filter. We used to use a field in the conn_rec, with this
5586 change, we use an argument to ap_get_brigade to determine how much
5587 data is retrieved. [Ryan Bloom]
5589 *) Fix seg fault at start-up introduced by Ryan's change to enable
5590 modules to specify their own logging tags. mod_log_config
5591 registers an optional function, ap_register_log_handler().
5592 ap_register_log_handler() was being called by http_core before
5593 the directive hash table was created. This patch creates the
5594 directive hash table before ap_register_log_handler() is
5595 registered as an optional function.
5596 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
5598 *) Add ap_set_int_slot() function
5599 [John K. Sterling <sterling covalent.net>]
5601 *) Under certain circumstances, Apache did not supply the
5602 right response headers when requiring authentication.
5603 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
5604 (This is a port of the change that went into Apache 1.3.19.)
5606 *) Allow modules to specify their own logging tags. This basically
5607 allows a module to tell mod_log_config that when %x is encountered
5608 a specific function should be called. Currently, x can be any single
5609 character. It may be more useful to make this a string at some point.
5612 Changes with Apache 2.0.17
5614 *) If a higher-level filter handles the byterange aspects of a
5615 request, then the byterange filter should not try to redo the
5616 work. The most common case of this happening, is a byterange
5617 request going through the proxy, and the origin server handles
5618 the byterange request. The proxy should ignore it.
5619 [Graham Leggett <minfrin sharp.fm>]
5621 *) Changed the threaded mpm to have child_main join to each of the
5622 worker threads to make sure the kids are all gone before child_main
5623 exits after a signal (cleanup from perform_idle_server_maintenance).
5624 This is an extension of Ryans recent commit to make the child_main
5627 *) Add more options to the ap_mpm_query function. This also allows MPMs to
5628 report if their threads are dynamic or static. Finally, this also
5629 implements a new API, ap_show_mpm, which returns the MPM that was
5630 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
5632 *) Do not install the binaries from the support directory twice.
5633 [jun-ichiro hagino <itojun iijlab.net>]
5635 *) The ap_f* functions should flush data to the filter that is passed
5636 in, not the filter after the one passed in.
5637 [Ryan Morgan <rmorgan covalent.net>]
5639 *) Make ab work again by changing its native types to apr types and formats.
5640 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
5642 *) Move the byterange filter and all of the supporting functions back
5643 to the HTTP module. The byterange filter turned out to be very
5644 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
5646 *) Make clean, distclean, and extraclean consistently according to the
5647 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
5649 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
5650 This may have been causing problems stopping processes in the threaded
5653 *) Fix content-length in mod_negotiation to a long int representation.
5656 *) Remove BindAddress from the default config file.
5657 [<giles nemeton.com.au>]
5659 *) Allow module authors to add a module to their Apache build using
5660 --with-module, without re-running buildconf. The syntax is:
5661 --with-module=module_type:/path/to/module.c
5662 The configure script will copy the module.c file to
5663 modules/module_type, and it will be added to the relevant Makefiles.
5664 currently, this only works for static modules. [Ryan Bloom]
5666 *) Changes required to make prefork clean up idle children properly.
5667 There was a window during which a starting worker deadlocks when
5668 an idle cleanup arrives before it completes init. Apache then keeps
5669 trying to cleanup the same deadlocked worker forever (until higher
5670 pids come along, but it still will never reduce below the deadlocked
5671 pid). Thus the number of children would not reduce to the correct
5672 idle level. [Paul J. Reder]
5674 Changes with Apache 2.0.16
5676 *) Change the default installation directory to /usr/local/apache2,
5677 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
5679 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
5682 *) Get MaxRequestsPerChild working with the Windows MPM.
5685 *) Make generic hooks to work, with mod_generic_hook_import/export
5686 experimental modules. [Ben Laurie, Will Rowe]
5688 *) Fix segfaults for configuration file syntax errors such as
5689 "<Directory>" followed by "</Directory" and
5690 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
5692 *) Cleanup the --enable-layout option of configure. This makes
5693 us use a consistent location for the config.layout file, and it
5694 makes configure more portable.
5695 [jun-ichiro hagino <itojun iijlab.net>]
5697 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
5698 csv/gnuplot format, rudimentary ssl support and various other tweaks
5699 to make results more true to what is measured. The upshot of this it
5700 turns out that 'ab' has often underreported the true performance of
5701 apache. Often by a order of magnitude :-) See talk/paper of Sander
5702 Temme at April ApacheCon 2001 for details.
5703 [Dirk-Willem van Gulik]
5705 *) Clean up mod_cgid's temporary request pool. Besides fixing a
5706 storage leak this ensures that some unnecessary pipes are closed.
5709 *) Performance: Add quick_handler hook. This hook is called at the
5710 very beginning of the request processing before location_walk,
5711 translate_name, etc. This hook is useful for URI keyed content
5712 caches like Mike Abbott's Quick Shortcut Cache.
5715 *) top_module global variable renamed to ap_top_module [Perl]
5717 *) Move ap_set_last_modified to the core. This is a potentially
5718 controversial change, because this is kind of HTTP specific. However
5719 many protocols should be able to take advantage of this kind of
5720 information. I expect that headers will need one more layer of
5721 indirection for multi-protocol work, but this is a small step in
5722 the right direction. [Ryan Bloom]
5724 *) Enable mod_status by default. This matches what Apache 1.3 does.
5727 *) Add a ScriptSock directive to the default config file. This is
5728 only enabled when mod_cgid is used.
5729 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5731 Changes with Apache 2.0.15
5733 *) Untangled the buildconf script and eliminated the need for build's
5734 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
5735 libtool muck that is now under srclib/apr/build. [Roy Fielding]
5737 *) Win32: Don't accept more connections than we have worker threads
5741 *) Fix bug in the Unix threaded.c MPM that allowed child processes
5742 to fork() new child processes.
5745 *) SECURITY: Fix a major security problem with double-reverse lookup
5746 checking. Previously, a client connecting over IPv4 would not be
5747 matched properly when the server had an IPv6 listening socket.
5748 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
5750 *) Change the way the beos MPM handles polling to allow it to stop and
5751 restart. Problem was the sockets being polled were being reset by
5752 the select call, so once it had accepted a connection it was no
5753 longer listening on the UDP socket we use for shutdown instructions.
5754 APR needs to be altered, patch on it's way. [David Reid]
5756 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
5757 on error exit from ap_getline(). Some other code got upset because
5758 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
5760 *) Handle ap_discard_request_body() being called more than once.
5761 [Greg Ames, Jeff Trawick]
5763 *) Get rid of an inadvertent close of file descriptor 2 in
5764 mod_mime_magic. [Greg Ames, Jeff Trawick]
5766 *) Add a hook, create_request. This hook allows modules to modify
5767 a request while it is being created. This hook is called for all
5768 request_rec's, main request, sub request, and internal redirect.
5769 When this hook is called, the r->main, r->prev, r->next
5770 pointers have been set, so modules can determine what kind of
5771 request this is. [Ryan Bloom]
5773 *) Cleanup the build process a bit more. The Apache configure
5774 script no longer creates its own helper scripts, it just
5776 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
5778 *) Stop the forced downgrade of the connection to HTTP/1.0 for
5779 proxy requests. [Graham Leggett]
5781 *) Avoid using sscanf to determine the HTTP protocol number in
5782 the common case because sscanf is a performance hog. From
5783 Mike Abbot's Accelerating Apache patch number 6.
5784 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
5786 *) SECURITY: Fix a security exposure in mod_access. Previously when
5787 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
5788 were not evaluated properly (PR #7407). Also, add the ability to
5789 specify IPv6 address strings with optional prefix length on Allow
5790 and Deny. [Jeff Trawick]
5792 *) Enhance rotatelogs so that a UTC offset can be specified, and
5793 the logfile name can be formatted using strftime(3). (Brought
5794 forward from 1.3.) [Ken Coar]
5796 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
5797 DuplicateHandle on an IOCompletionPort (a practice which
5798 MS "discourages"). The new model does not rely on associating
5799 the completion port with the listening sockets, thus the
5800 completion port can be completely managed within the child
5801 process. A dedicated thread accepts connections off the network,
5802 then calls PostQueuedCompletionStatus() to wake up worker
5803 threads blocked on the completion port.
5806 *) Bring forward the --suexec-umask option which allows the
5807 builder to preset the umask for suexec processes. [Ken Coar]
5809 *) Add a -V flag to suexec, which causes it to display the
5810 compile-time settings with which it was built. (Only
5811 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
5813 *) Mod_include should always unset the content-length if the file is
5814 going to be passed through send_parsed_content. There is no to
5815 determine if the content will change before actually scanning the
5816 entire content. It is far safer to just remove the C-L as long
5817 as we are scanning it. [Ryan Bloom]
5819 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
5820 request and not Proxy-Authenticate.
5821 [Graham Leggett <minfrin sharp.fm>]
5823 Changes with Apache 2.0.14
5825 *) Fix content-length computation. We ONLY compute a content-length if
5826 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
5827 or we already have all the data. [Ryan Bloom]
5829 *) Report unbounded containers in the config file. Previously, a typo
5830 in the </container> directive could result in the rest of the config
5831 file being silently ignored, with undesired defaults used.
5834 *) Make the old_write filter use the ap_f* functions for the buffering.
5837 *) Move more code from the http module into the core server. This
5838 is core code, basically the default handler, the default input
5839 and output filters, and all of the core configuration directives.
5840 All of this code is required in order for the server to work, with or
5841 without HTTP. The server is closer to working without the HTTP
5842 module, although there is still more to do. [Ryan Bloom]
5844 *) Fix a number of SGI compile warnings throughout the server. Fix some
5845 bad parameters to apr_bucket_read(). Fix a bad statement in
5846 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
5847 consistently; we were mixing apr_time_t and time_t in invalid ways
5848 before. In load_file(), call apr_dso_error() instead of
5849 apr_strerror() so that we get a more specific string on some platforms.
5850 PR #6980 [Jeff Trawick]
5852 *) Allow modules to query the MPM about it's execution profile. This
5853 query API can and should be extended in the future, but for now,
5854 max_daemons, and threading or forking is a very good start.
5855 [Jon Travis <jtravis covalent.net>]
5857 *) Modify mod_include to send blocks of data no larger than 9k.
5858 Without this, mod_include will wait until the whole file is parsed,
5859 or the first tag is found to send any data to the client.
5860 [Paul J. Reder <rederpj raleigh.ibm.com>]
5862 *) Fix mod_info, so that <Directory> and <Location> directives are
5863 not displayed twice when displaying the current configuration.
5864 [Ryan Morgan <rmorgan covalent.net>]
5866 *) Add config directives to override DEFAULT_ERROR_MSG and
5867 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
5868 [Dan Rench <drench xnet.com>]
5870 *) Get mod_info building and loading on Win32. [William Rowe]
5872 *) Begin to move protocol independant functions out of mod_http. The goal
5873 is to have only functions that are HTTP specific in the http directory.
5876 Changes with Apache 2.0.13
5878 *) Don't assume that there will always be multiple calls to the byterange
5879 filter. It is possible that we will need to do byteranges with only
5880 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
5882 *) Move the error_bucket definition from the http module to the
5883 core server. Every protocol will need this ability, not just
5886 Changes with Apache 2.0.12
5888 *) Modify mod_file_cache to save pre-formatted strings for
5889 content-length and last-modified headers for performance.
5890 [Mike Abbot <mja trudge.engr.sgi.com>]
5892 *) Namespace protect IOBUFSIZ since it is exposed in the API.
5893 [Jon Travis <jtravis covalent.net>]
5895 *) Use "Basic" authentication instead of "basic" in ab, as the spec
5896 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
5898 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
5899 without ever filling it out. This fixes PR 7271.
5900 [Taketo Kabe <kabe sra-tohoku.co.jp> and
5901 Cliff Woolley <cliffwoolley yahoo.com>]
5903 *) Add a couple of GCC attribute tags to printf style functions.
5904 [Jon Travis <jtravis covalent.net>]
5906 *) Add the correct language tag for interoperation with the Taiwanese
5907 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
5909 *) Migrate the perchild MPM to use the new apr signal child, and
5910 APR thread functions. [Ryan Bloom]
5912 *) Close one copy of the CGI's stdout before creating the new process.
5913 The CGI will still have stdout, because we have already dup'ed it.
5914 This keeps Apache from waiting forever to send the results of a CGI
5915 process that has forked a long-lived child process.
5916 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5918 *) Remove the rest of the pthreads functions from the threaded MPM.
5919 This requires the APR support for a signal thread that was just
5922 *) Make mod_dir use a fixup for sending a redirect to the browser.
5923 Before this, we were using a handler, which doesn't make much
5924 sense, because the handler wasn't generating any data, it would
5925 either return a redirect error code, or DECLINED. This fits the
5926 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
5928 *) Make the threaded MPM use APR threads instead of pthreads.
5931 *) Get mod_tls to the point where it actually appears to work in all cases.
5934 *) implement --enable-modules and --enable-mods-shared for "all" and
5935 "most". [Greg Stein]
5937 *) Move the threaded MPM to use APR locks instead of pthread locks.
5940 *) Rename mpmt_pthread to threaded. This is more in line with the
5941 fact that mpmt_pthread shouldn't be using pthreads directly, and
5942 it is a smaller name that doesn't tie into anything.
5945 *) Rename the module structures so that the exported symbol matches
5946 the file name, and it is easier to automate the installation
5947 process (generating LoadModule directives from the module filenames).
5950 *) Remove the coalesce filter. With the ap_f* functions, this filter
5951 is no longer needed. [Ryan Bloom]
5953 Changes with Apache 2.0.11
5955 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
5956 added feature of allowing a uid/gid per child process. If no
5957 uid/gid is specified, then Perchild behaves exactly like dexter.
5960 *) Get perchild building again. [Ryan Bloom]
5962 *) Don't disable threads just because we are using the prefork MPM.
5963 If somebody wants to compile without threads, they must now add
5964 --disable-threads to the configure command line. [Ryan Bloom]
5966 *) Begin to move the calls to update_child_status into common code, so
5967 that each individual MPM does not need to update the scoreboard itself.
5970 *) Allow mod_tls to compile under Unix boxes where openssl has been
5971 installed to the system include files.
5972 [Gomez Henri <new-httpd slib.fr>]
5974 *) Cleanup the mod_tls configure process. This should remove any need
5975 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
5976 configure doesn't check that yet. [Ryan Bloom]
5978 *) Add a very early prototype of SSL support (in mod_tls.c). It is
5979 vital that you read modules/tls/README before attempting to build
5982 *) Fix a potential seg fault on all platforms. David Reid fixed this
5983 on BEOS, but the problem could happen anywhere, so we don't want
5984 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
5986 *) Add new LogFormat directive, %D, to log time it takes to serve a
5987 request in microseconds. [Bill Stoddard]
5989 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
5990 SetOutputFilter. This corresponds nicely with the other Set
5991 directives, which operate on containers while the Add* directives
5992 tend to work directly on extensions. [Ryan Bloom]
5994 *) Cleanup the header handling a bit. This uses the apr_brigade_*
5995 functions for the buffering so that we don't need to compute
5996 the length of the headers before we actually create the header
5997 buffer. [Ryan Bloom]
5999 *) Allow filters to buffer data using the ap_f* functions. These have
6000 become macros that resolve directly to apr_brigade_*.
6003 *) Get the Unix MPM's to do a graceful restart again. If we are going
6004 to register a cleanup with ap_cleanup_scoreboard, then we have to
6005 kill the cleanup with the same function, and that function can't be
6006 static. [Ryan Bloom]
6008 *) Install all required header files. Without these, it was not
6009 possible to compile some modules outside of the server.
6012 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
6013 forward from 1.3 to 2.0, we missed a single line, which broke regex
6014 aliases. [Ryan Bloom]
6016 *) We have a poor abstraction in the protocol. This is a temporary
6017 hack to fix the bug, but it will need to be fixed for real. If
6018 we find an error while sending out a custom error response, we back
6019 up to the first non-OK request and send the data. Then, when we send
6020 the EOS from finalize_request_protocol, we go to the last request,
6021 to ensure that we aren't sending an EOS to a request that has already
6022 received one. Because the data is sent on a different request than
6023 the EOS, the error text never gets sent down the filter stack. This
6024 fixes the problem by finding the last request, and sending the data
6025 with that request. [Ryan Bloom]
6027 *) Make the server status page show the correct restart time, and
6028 thus the proper uptime. [Ryan Bloom]
6030 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
6031 should reduce the amount of duplicate code that is required to
6032 create CGI processes.
6033 [Paul J. Reder <rederpj raleigh.ibm.com>]
6035 *) ap_new_connection() closes the socket and returns NULL if a socket
6036 call fails. Usually this is due to a connection which has been
6037 reset. [Jeff Trawick]
6039 *) Move the Apache version information out of httpd.h and into release.h.
6040 This is in preparation for the first tag with the new tag and release
6041 system. [Ryan Bloom]
6043 *) Begin restructuring scoreboard code to enable adding back in
6044 the ability to use IPC other than shared memory.
6045 Get mod_status working on Windows again. [Bill Stoddard]
6047 *) Make mod_status work with 2.0. This will work for prefork,
6048 mpmt_pthread, and dexter. [Ryan Bloom]
6050 *) Correct a typo in httpd.conf.
6051 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
6053 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
6055 *) Get the correct IP address if ServerName isn't set and we can't
6056 find a fully-qualified domain name at startup.
6057 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
6059 *) Make mod_cgid work with SuExec. [Ryan Bloom]
6061 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
6062 'extra' stat's for user/group since they should never occur, and now
6063 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
6064 volumes. [William Rowe]
6066 *) Adopt apr features to simplify mod_includes. This changes the
6067 behavior of the USER_NAME variable, unknown uid's are now reported
6068 as USER_NAME="<unknown>" rather than the old user#000 result.
6069 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
6071 *) Adopt apr features for simplifing mod_userdir, and accept the new
6072 Win32/OS2 exceptions without hiccuping. [William Rowe]
6074 *) Replace configure --with-optim option by using and saving the
6075 environment variable OPTIM instead. This is needed because configure
6076 options do not support multiple flags separated by spaces.
6079 *) Fix some byterange handling. If we get a byte range that looks like
6080 "-999999" where that is past the end of the file, we should return
6081 a PARTIAL CONTENT status code, and return the whole file as one big
6082 byterange. This matches the 1.3 handling now. [Ryan Bloom]
6084 *) Make the error bucket a real meta-data bucket. This means that the
6085 bucket length is 0, and a read returns NULL data. If one of these
6086 buckets is passed down after the headers are sent, this data will
6087 just be ignored. [Greg Stein]
6089 *) The prefork MPM wasn't killing child processes correctly if a restart
6090 signal was received while the process was serving a request. The child
6091 process would become the equivalent of a second parent process. If
6092 we break out of the accept loop, then we need to do die after cleaning
6093 up after ourselves. [Ryan Bloom]
6095 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
6096 restarts. [Ryan Bloom]
6098 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
6099 the most optimal APR_FINFO_wanted bits. This spares Win32 from
6100 performing very expensive owner, group and permission lookups
6101 and allows the server to function until these apr_finfo_t fields
6102 are implemented under Win32. [William Rowe]
6104 *) Support for typedsafe optional functions - that is functions exported by
6105 optional modules, which, therefore, may or may not be present, depending
6106 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
6107 for sample code. [Ben Laurie]
6109 *) filters can now report an HTTP error to the server. This is done
6110 by sending a brigade where the first bucket is an error_bucket.
6111 This bucket is a simple bucket that stores an HTTP error and
6112 a string. Currently the string is not used, but it may be needed
6113 to output an error log. The http_header_filter will find this
6114 bucket, and output the error text, and then return
6115 AP_FILTER_ERROR, which informs the server that the error web page
6116 has already been sent. [Ryan Bloom]
6118 *) If we get an error, then we should remove all filters except for
6119 those critical to serving a web page. This fixes a bug, where
6120 error pages were going through the byterange filter, even though
6121 that made no sense. [Ryan Bloom]
6123 *) Relax the syntax checking of Host: headers in order to support
6124 iDNS. PR#6635 [Tony Finch]
6126 *) Cleanup the byterange filter to use the apr_brigade_partition
6127 and apr_bucket_copy functions. This removes a lot of very messy
6128 code, and hopefully makes this filter more stable.
6131 *) Remove AddModule and ClearModuleList directives. Both of these
6132 directives were used to ensure that modules could be enabled
6133 in the correct order. That requirement is now gone, because
6134 we use hooks to ensure that modules are in the correct order.
6137 *) When SuExec is specified, we need to add it to the list of
6138 targets to be built. If we don't, then any changes to the
6139 configuration won't affect SuExec, unless 'make suexec' is
6140 specifically run. [Ryan Bloom]
6142 *) Cleaned out open_file from mod_file_cache, as apr now accepts
6143 the APR_XTHREAD argument to open a file for consumption by
6144 parallel threads on win32. [William Rowe]
6146 *) Correct a bug in determining when we follow symlinks. The code
6147 expected a stat -1 result, not an apr_status_t positive error.
6148 Also check if the APR_FINFO_USER fields are valid before we
6149 follow the link. [William Rowe]
6151 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
6152 mpm_common.c. These functions are only valid on some platforms,
6153 so they should not be in the main-line code. [Ryan Bloom]
6155 *) Remove ap_chdir_file(). This function is not thread-safe,
6156 and nobody is currently using it. [Ryan Bloom]
6158 *) Do not try to run make depend if there are no .c files in the
6159 current directory, doing so makes `make depend` fail.
6162 *) Update highperformance.conf to work with either prefork or
6163 pthreads mpms. [Greg Ames]
6165 *) Stop checking to see if this is a pipelined request if we know
6166 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
6167 This keeps us from making an extra read call when serving a 1.0
6168 request. [Ryan Bloom and Greg Stein]
6170 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
6171 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
6172 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
6174 *) Fix the RFC number mentioned when complaining about a missing
6175 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
6177 *) Fix an endless loop in ab which occurred when ab was posting
6178 and the server dropped the connection unexpectedly.
6181 *) Fix a segfault while handling request bodies in ap_http_filter().
6182 This problem has been seen with mod_dav usage as well as with
6183 requests where the body was just being discarded. [Jeff Trawick]
6185 *) Some adjustment on the handling and automatic setting (via
6186 hints.m4) of various compilation flags (eg: CFLAGS). Also,
6187 add the capability to specify flags (NOTEST_CFLAGS and
6188 NOTEST_LDFLAGS) which are used to compile Apache, but
6189 not used during the configuration process. Useful for
6190 flags like "-Werror". [Jim Jagielski]
6192 *) Stop using environment variables to force debug mode or
6193 no detach. We now use the -D command line argument to
6194 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
6195 [Greg Stein, Ryan Bloom]
6197 *) Change handlers to use hooks. [Ben Laurie]
6199 *) Stop returning copies of filenames from both apr_file_t and
6200 apr_dir_t. We pstrdup the filenames that we store in the
6201 actual structures, so we don't need to pstrdup the strings again.
6204 *) mod_cgi: Fix some problems where the wrong error value was being
6205 traced. [Jeff Trawick]
6207 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
6210 *) Add generic hooks. [Ben Laurie]
6212 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
6214 *) Fix a segfault caused by mod_ext_filter when the external filter
6215 program does not exist. [Jeff Trawick]
6217 *) Fix an output truncation error when on an HTTP >= 1.0 request an
6218 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
6219 was served through mod_charset_lite (or anything else that would
6220 create a transient bucket in this size range). ap_bucket_make_heap()
6221 silently failed (fixed), transient_setaside() discovered it, but
6222 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
6224 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
6225 is that some browsers send extra lines at the end of POST requests, and
6226 we don't want to delay sending data back to the user just because the
6227 browser isn't well behaved. [Ryan Bloom]
6229 *) Get SuEXEC working again. We can't send absolute paths to suExec
6230 because it refuses to execute those programs. SuEXEC also wasn't
6231 always recognizing configuration changes made using the autoconf
6234 *) Allow the buildconf process to find the config.m4 files in the correct
6235 order. Basically, we can now name config.m4 files as config\d\d.m4,
6236 and we will sort them correctly when inserting them into the build
6237 process. [Ryan Bloom]
6239 *) Get mod_cgid to use apr calls for creating the actual CGI process.
6240 This also allows mod_cgid to use ap_os_create_priviledged_process,
6241 thus allowing for SuExec execution from mod_cgid. Currently, we do
6242 not support everything that standard SuExec supports, but at least
6243 it works minimally now. [Ryan Bloom]
6245 *) Allow SuExec to be configured from the ./configure command line.
6248 *) Update some of the docs in README and INSTALL to reflect some of
6249 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
6251 *) If we get EAGAIN returned from the call to apr_sendfile, then we
6252 need to call sendfile again. This gets us serving large files
6253 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
6255 *) Get the support programs building cleanly again.
6256 [Cliff Woolley <cliffwoolley yahoo.com>]
6258 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
6259 current directory logic now backs up over bin/ to determine the
6260 server root from the Apache.exe path.
6262 *) Apache/Win32 now follows the standard conventions of mod_foo.so
6263 loadable modules, dynamic libs are all named libfoo.dll, and the
6264 makefile.win populates the include, lib and libexec directories.
6266 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
6267 Apache gets IPv6 listening sockets by default. Additionally, the
6268 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
6269 numeric address strings (e.g., "Listen [fe80::1]:8080").
6272 *) Modify the install directory layout. Modules are now installed in
6273 modules/. Shared libraries should be installed in libraries/, but
6274 we don't have any of those on Unix yet. All install directories
6275 are modifyable at configure time. [Ryan Bloom]
6277 *) Install all header files in the same directory on Unix. [Ryan Bloom]
6279 *) Get the functions in server/linked into the server, regardless of
6280 which modules linked into the server. This uses the same hack
6281 for Apache that we use for APR and apr-util to ensure all of the
6282 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
6283 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
6284 the scripts a bit easier.
6287 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
6288 on the query, and remove IPv4 dependencies. [Jeff Trawick]
6290 *) Get all of the auth modules to the point that they will install and
6291 be loadable into the server. Our new build/install mechanism expects
6292 that all modules will have a common name format. The auth modules
6293 didn't use that format, so we didn't install them properly.
6296 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
6297 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
6299 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
6301 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
6302 after the end of the response. [Ryan Bloom]
6304 *) Get byterange requests working with responses that do not have a
6305 content-length. Because of the way byterange requests work, we have to
6306 have all of the data before we can actually do the byterange, so we
6307 can compute the content-length in the byterange filter.
6310 *) Get exe CGI's working again on Windows.
6313 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
6314 they keep track of whether or not their post config hook has been
6315 called before. Instead of a static variable (which is replaced when
6316 the DSO is loaded a second time), use userdata in the process pool.
6319 Changes with Apache 2.0a9
6321 *) Win32 now requires perl to complete the final install step for users
6322 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
6323 and installs the conf, htdocs and htdocs/manual directories.
6326 *) Make mod_include use a hash table to associate directive tags with
6327 functions. This allows modules to implement their own SSI tags easily.
6328 The idea is simple enough, a module can insert it's own tag and function
6329 combination into a hash table provided by mod_include. While mod_include
6330 parses an SSI file, when it encounters a tag in the file, it does a
6331 hash lookup to find the function that implements that tag, and passes
6332 all of the relevant data to the function. That function is then
6333 responsible for processing the tag and handing the remaining data back
6334 to mod_include for further processing.
6335 [Paul J. Reder <rederpj raleigh.ibm.com>]
6337 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
6338 fewer parameters: the local and remote socket addresses were removed
6339 from the parameter list because all required information is available
6340 via the APR socket. [Jeff Trawick]
6342 *) Distribution directory structure reorganized to reflect a
6343 normal source distribution with external install targets.
6346 *) The MPMs that need multiple segments of shared memory now create
6347 two apr_shmem_t variables, one for each shared memory allocation.
6348 the problem is that we can't determine how much memory will be required
6349 for shared memory allocations once we try to allocate more than one
6350 variable. The MM code automatically aligns the shared memory allocations,
6351 so we end up needing to pad the amount of shared memory we want based
6352 on how many variables will be allocated out of the shared memory segment.
6353 It is just easier to create a second apr_shmem_t variable, and two
6354 shmem memory blocks.
6357 *) Cleanup the export list a bit. This creates a single unified list of
6358 functions exported by APR. The export list is generated at configure
6359 time, and that list is then used to generate the exports.c file.
6360 Because of the way the export list is generated, we only export those
6361 functions that are valid on the platform we are building on.
6364 *) Enable logging the cookie with mod_log_config
6365 [Sander van Zoest <sander covalent.net>]
6367 *) Fix a segfault in mod_info when it reaches the end of the configuration.
6370 *) Added lib/aputil/ as a placeholder for utility functions which are not
6371 specific to the Apache HTTP Server (but do not make sense with APR).
6372 The first utility is "apu_dbm": a set of functions to work with DBM
6373 files. This first version can be compiled for SDBM or GDBM databases.
6376 *) Complete re-write of mod_include. This makes mod_include a filter that
6377 uses buckets directly. This has now served the FAQ correctly.
6378 [Paul Reder <rederpj raleigh.ibm.com>]
6380 *) Allow modules to specify the first filter in a sub_request when
6381 making the sub_request. This keeps modules from having to change the
6382 output_filter immediately after creating the sub-request, and therefore
6383 skip the sub_req_output_filter. [Ryan Bloom]
6385 *) Update ab to accept URLs with IPv6 literal address strings (in the
6386 format described in RFC 2732), and to build Host header fields in
6387 the same format. This allows IPv6 literal address strings to be
6388 used with ab. This support has been tested against Apache 1.3 with
6389 the KAME patch, but Apache 2.0 does not yet work with this format
6390 of the Host header field. [Jeff Trawick]
6392 *) Accomodate an out-of-space condition in the piped logs and the
6393 rotatelogs.c code, and no longer churn log processes for this
6394 condition. [Victor J. Orlikowski]
6396 *) Add support for partial writes with apr_sendfile() to core_output_filter.
6399 Changes with Apache 2.0a8
6401 *) Add a directive to mod_mime so that filters can be associated with
6405 *) Get multi-views working again. We were setting the path_info
6406 field incorrectly if we couldn't find the specified file.
6409 *) Fix 304 processing. The core should never try to send the headers
6410 down the filter stack. Always, just setup the table in the request
6411 record, and let the header filter convert it to data that is ready
6415 *) More fixes for the proxy. There are still bugs in the proxy code,
6416 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
6420 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
6423 *) APR: Add new apr_getopt_long function to handle long options.
6424 [B. W. Fitzpatrick <fitz red-bean.com>]
6426 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
6427 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
6428 hostname resolution/address string parsing and building
6429 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
6430 of one of the apr_sockaddr_t structures for a socket. Change
6431 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
6433 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
6434 I have proxied pages with it, cleanup will commence soon.
6437 *) Make the proxy work with filters. This isn't perfect, because we
6438 aren't dealing with the headers properly. [Ryan Bloom]
6440 *) Do not send a content-length iff the C-L is 0 and this is a head
6441 request. [Ryan Bloom]
6443 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
6444 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
6446 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
6448 *) Get the default_handler to stop trying to deal with HEAD requests.
6449 The idea is to let the content-length filter compute the C-L before
6450 we try to send the data. If we can get the C-L correctly, then we
6451 should send it in the HEAD response.
6454 *) The Header filter can now determine if a body should be sent based
6455 on r->header_only. The general idea of this is that if we delay
6456 deciding to send the body, then we might be able to compute the
6457 content-length correctly, which will help caching proxies to cache
6458 our data better. Any handler that doesn't want to try to compute
6459 the content-length can just send an EOS bucket without data and
6460 everything will just work.
6463 *) Add the referer to the error log if one is available.
6464 [Markus Gyger <mgyger itr.ch>]
6466 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
6467 change, the root of the configuration tree has been exposed to modules
6469 [Ryan Morgan <rmorgan covalent.net>]
6471 *) Get the core_output_filter to use the bucket interface directly.
6472 This keeps us from calling the content-length filter multiple times
6473 for a simple static request.
6476 *) We are sending the content-type correctly now.
6477 [Ryan Bloom and Will Rowe]
6479 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
6480 a bogus bytes-sent value when the only thing being sent was trailers
6481 and writev() returned an error (or EAGAIN). [Jeff Trawick]
6483 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
6484 hints file to determine which platforms define
6485 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
6488 *) APR: add apr_get_home_directory() [Jeff Trawick]
6490 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
6492 *) Not all platforms have INADDR_NONE defined by default. Apache
6493 used to make this check and define INADDR_NONE if appropriate,
6494 but APR needs the check too, and I suspect other applications will
6495 as well. APR now defines APR_INADDR_NONE, which is always a valid
6496 value on all platforms.
6497 [Branko Čibej <brane xbc.nu>]
6499 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
6500 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
6502 *) Relax the syntax checking of Host: headers in order to support
6503 iDNS. PR#6635 [Tony Finch]
6505 *) When reading from file buckets we convert to an MMAP if it makes
6506 sense. This also simplifies the default handler because the
6507 default handler no longer needs to try to create MMAPs.
6510 *) BUFF has been removed from the main server. The BUFF code will remain
6511 in the code until it has been purged from the proxy module as well.
6514 *) Byteranges have been completely re-written to be a filter. This
6515 has been tested, and I believe it is working correctly, but it could
6516 doesn't work for the Adobe Acrobat plug-in. The output almost matches
6517 the output from 1.3, the only difference being that 1.3 includes
6518 a content-length in the response, and this does not.
6521 *) APR read/write functions and bucket read functions now operate
6522 on unsigned integers, instead of signed ones. It doesn't make
6523 any sense to use signed ints, because we return the error codes,
6524 so if we have an error we should report 0 bytes read or written.
6527 *) Always compute the content length, whether it is sent or not.
6528 The reason for this, is that it allows us to correctly report
6529 the bytes_sent when logging the request. This also simplifies
6530 content-length filter a bit, and fixes the actual byte-reporing
6531 code in mod_log_config.c
6534 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
6535 it says, because it was only used by EOS and FLUSH buckets. Since
6536 neither of those are required at the end of a brigade, this was
6537 really signifying FLUSH_THE_DATA, but that can be determined better
6538 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
6539 buckets now return a length of 0, which is actually the amount of data
6540 read, so they make more sense.
6543 *) Allow the core_output_filter to save some data past the end of a
6544 request. If we get an EOS bucket, we only send the data if it
6545 makes sense to send it. This allows us to pipeline request
6546 responses. As a part of this, we also need to allocate mmap
6547 buckets out of the connection pool, not the request pool. This
6548 allows the mmap to outlive the request.
6551 *) Make blocking and non-blocking bucket reads work correctly for
6552 sockets and pipes. These are the only bucket types that should
6553 have non-blocking reads, because the other bucket types should
6554 ALWAYS be able to return something immediately.
6557 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
6558 server, but use Ctrl+Break to initiate a graceful restart
6559 instead of duplicating behavior. [John Sterling]
6561 *) Patch mod_autoindex to set the Last-Modified header based on
6562 the directory's mtime, and add the ETag header. [William Rowe]
6564 *) Merge the 1.3 patch to add support for logging query string in
6565 such a way that "%m %U%q %H" is the same as "%r".
6568 *) Port three log methods from mod_log_config 1.3 to 2.0:
6569 CLF compliant '-' byte count, method and protocol.
6572 *) Add a new LogFormat directive, %c, that will log connection
6573 status at the end of the response as follows:
6574 'X' - connection aborted before the response completed.
6575 '+' - connection may be kept-alive by the server.
6576 '-' - connection will be closed by the server.
6579 *) Expand APR for WinNT to fully accept and return utf-8 encoded
6580 Unicode file names and paths for Win32, and tag the Content-Type
6581 from mod_autoindex to reflect that charset if the feature
6582 macro APR_HAS_UNICODE_FS is true. [William Rowe]
6584 *) Compute the content length (and add appropriate header field) for
6585 the response when no content length is available and we can't use
6586 chunked encoding. [Jeff Trawick]
6588 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
6589 so that content input filters get dechunked data when using
6590 the default handler. Also removed REQUEST_CHUNKED_PASS.
6593 *) Add mod_ext_filter as an experimental module. This module allows
6594 the administrator to use external programs as filters. Currently,
6595 only filtering of output is supported. [Jeff Trawick]
6597 *) Most Apache functions work on EBCDIC machines again, as protocol
6598 data is now translated (again). [Jeff Trawick]
6600 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
6601 the EBCDIC support. They are noops on ASCII machines, so this
6602 type of translation doesn't have to be surrounded by #ifdef
6603 CHARSET_EBCDIC. [Jeff Trawick]
6605 *) Fix mod_include. tag commands work again, and the server will
6606 send the FAQ again. This also allows mod_include to set aside
6607 buckets that include partial buckets.
6608 [Ryan Bloom and David Reid]
6610 *) Add suexec support back. [Manoj Kasichainula]
6612 *) Lingering close now uses the socket directly instead of using
6613 BUFF. This has been tested, but since all we can tell is that it
6614 doesn't fail, this needs to be really hacked on.
6617 *) Allow filters to modify headers and have those headers be sent to
6618 the client. The idea is that we have an http_header filter that
6619 actually sends the headers to the network. This removes the need
6620 for the BUFF to send headers.
6623 *) Charset translation: mod_charset_lite handles translation of
6624 request bodies. Get rid of the xlate version of ap_md5_digest()
6625 since we don't compute digests of filtered (e.g., translated)
6626 response bodies this way anymore. (Note that we don't do it at
6627 all at the present; somebody needs to write a filter to do so.)
6630 *) Input filters and ap_get_brigade() now have a input mode parameter
6631 (blocking, non-blocking, peek) instead of a length parameter.
6634 *) Update the mime.types file to the registered media types as
6635 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
6638 *) Namespace protect some macros declared in ap_config.h
6641 *) Support HTTP header line folding with input filtering.
6644 *) Mod_include works again. This should still be re-written, but at
6645 least now we can serve an SHTML page again.
6648 *) Begin to remove BUFF from the core. Currently, we keep a pointer
6649 to both the BUFF and the socket in the conn_rec. Functions that
6650 want to use the BUFF can, functions that want to use the socket,
6651 can. They point to the same place.
6654 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
6655 [Tomas Ögren <stric ing.umu.se>]
6657 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
6658 associated pool goes away. (APR pipes on OS/2 were already had this
6659 logic.) This resolvs a fatal file descriptor leak with CGIs.
6662 *) The final line of the config file was not being read if there was
6663 no \n at the end of it. This was caused by apr_fgets returning
6664 APR_EOF even though we had read valid data. This is solved by
6665 making cfg_getline check the buff that was returned from apr_fgets.
6666 If apr_fgets return APR_EOF, but there was data in the buf, then we
6667 return the buf, otherwise we return NULL.
6670 *) Piped logs work again in the 2.0 series.
6673 *) Restore functionality broken by the mod_rewrite security fix:
6674 rewrite map lookup keys and default values are now expanded
6675 so that the lookup can depend on the requested URI etc.
6676 PR #6671 [Tony Finch]
6678 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
6679 security bug in some mass virtual hosting configurations
6680 that can allow a remote attacker to retrieve some files
6681 on the system that should be inaccessible. [Tony Finch]
6683 *) Add a pool bucket type. This bucket is used for data allocated out
6684 of a pool. If the pool is cleaned before the bucket is destroyed, then
6685 the data is converted to a heap bucket, allowing it to survive the
6689 *) Add a flush bucket. This allows modules to signal that the filters
6690 should all flush whatever data they currently have. There is no way
6691 to actually force them to do this, so if a filter ignores this bucket,
6692 that's life, but at least we can try with this.
6695 *) Add an output filter for sub-requests. This filter just strips the
6696 EOS bucket so that we don't confuse the main request's core output
6697 filter by sending multiple EOS buckets. This change also makes sub
6698 requests start to send EOS buckets when they are finished.
6701 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
6702 makes ap_bucket_destroy a return void, which is okay because it
6703 used to always return APR_SUCCESS, and nobody ever checked its
6704 return value anyway.
6705 [Cliff Woolley <cliffwoolley yahoo.com>]
6707 *) Remove the index into the bucket-type table from the buckets
6708 structure. This has now been replaced with a pointer to the
6709 bucket_type. Also add some macros to test the bucket-type.
6712 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
6713 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
6714 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
6715 All _VAR_ flavors changes to _DATA to be absolutely clear.
6718 *) Add support for /, //, //servername and //server/sharename
6719 parsing of <Directory> blocks under Win32 and OS2.
6720 [Tim Costello, William Rowe, Brian Harvard]
6722 *) Remove the function pointers from the ap_bucket type. They have been
6723 replaced with a global table. Modules are allowed to register bucket
6724 types and use then use those buckets.
6727 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
6728 once we finish writing the request body to the cgi child process;
6729 otherwise, the client doesn't hit EOF on stdin. Small request bodies
6730 worked without this change (for reasons I don't understand), but large
6731 ones didn't. [Jeff Trawick]
6733 *) Remove file bucket specific information from the ap_bucket type.
6734 This has been moved to a file_bucket specific type that hangs off
6735 the data pointer in the ap_bucket type.
6738 *) Input filtering now has a third argument. This is the amount of data
6739 to read from lower filters. This argument can be -1, 0, or a positive
6740 number. -1 means give me all the data you have, I'll deal with it and
6741 let you know if I need more. 0 means give me one line and one line
6742 only. A positive number means I want no more than this much data.
6744 Currently, only 0 and a positive number are implemented. This allows
6745 us to remove the remaining field from the conn_rec structure, which
6749 *) Big cleanup of the input filtering. The goal is that http_filter
6750 understands two conditions, headers and body. It knows where it is
6751 based on c->remaining. If c->remaining is 0, then we are in headers,
6752 and http_filter returns a line at a time. If it is not 0, then we are
6753 in body, and http_filter returns raw data, but only up to c->remaining
6754 bytes. It can return less, but never more.
6755 [Greg Ames, Ryan Bloom, Jeff Trawick]
6757 *) mod_cgi: Write all of the request body to the child, not just what
6758 the kernel would accept on the first write. [Jeff Trawick]
6760 *) Back out the change that moved the brigade from the core_output_filters
6761 ctx to the conn_rec. Since all requests over a given connection
6762 go through the same core_output_filter, the ctx pointer has the
6766 *) Fix another bug in the send_the_file() read/write loop. A partial
6767 send by apr_send would cause unsent data in the read buffer to
6768 get clobbered. Complete making send_the_file handle partial
6769 writes to the network.
6772 *) Fix a couple of type fixes to allow compilation on AIX again
6773 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
6775 *) Fix bug in send_the_file() which causes offset to be ignored
6776 if there are no headers to send.
6779 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
6780 filter. Useful for supporting Windows 9* with a binary
6781 compiled on Windows NT.
6784 Changes with Apache 2.0a7
6786 *) Reimplement core_output_filter to buffer/save bucket brigades
6787 across multiple calls to the core_filter. The brigade will be
6788 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
6789 thresholds are hit or the EOS bucket is received.
6792 *) Create experimental filter (buffer_filter) that coalesces bytes
6793 into one large buffer before invoking the next filter in the
6794 chain. This filter is particularly useful with the current
6795 implementation of mod_autoindex when it inserted above the
6796 chunk_filter. mod_autoindex generates a lot of brigades that
6797 containing buckets holding just a few bytes each. The
6798 buffer_filter coalesces these buckets into a single large bucket.
6801 *) Add apr_sendfile() support into the core_output_filter.
6804 *) Add apr_sendv() support into the core_output_filter.
6807 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
6808 [Mike Abbott <mja sgi.com>]
6810 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
6811 make much sense, because Apache uses buckets instead of BUFFs now.
6814 *) send_the_file now falls back to a read/write loop on platforms that
6815 do not have sendfile.
6816 [Ryan Bloom and Brian Havard]
6818 *) Install apachectl correctly, and substitute the proper values so
6819 that it works again. [Ryan Bloom]
6821 *) Better(??) handle platforms that lack sendfile().
6824 *) APR now has UUID generation/formatting/parsing support.
6827 *) Begin the http_filter. This is an input filter that understands
6828 the absolute basic amount required to parse an HTTP Request. The
6829 goal is to be able to split headers from request body before passing
6830 the data back to the other filters.
6833 *) Bring forward from 1.3.13 the config directory implementation
6836 *) install apxs if it is created
6839 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
6840 conversions. [William Rowe]
6842 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
6843 ap_add_output_filter(). [Jeff Trawick]
6845 *) Multiple build and configuration fixes
6848 -add datadir and localstatedir substitutions
6850 -fix logfilename misspelling
6851 -fix evaluation of installation dir variables and
6852 -replace $foobar by $(foobar) to be usefull in the makefile
6856 -add rules for cross-compiling in rules.mk. Okay, rule to check for
6857 $CC_FOR_BUILD is still missing
6858 -use CHECK_TOOL instead of CHECK_PROG for ranlib
6859 -add missing "AR=@AR@" to severaly Makefile.in's
6860 -cache result for "struct rlimit"
6861 -compile all helper programs with native and cross compiler
6862 and use the native version to generate header file
6863 [Rüdiger Kuhlmann <Tadu gmx.de>]
6865 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
6867 [Rüdiger Kuhlmann <Tadu gmx.de>]
6869 *) Fix a bug where a client which only sends \n to delimit header
6870 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
6871 message. Start working on ebcdic co-existance with input
6873 [William Rowe, Greg Ames]
6875 *) If mod_so is enabled in the server always create libexec, even
6876 if there are no modules installed in this directory. This is a
6877 requirement for APXS to work correctly.
6880 *) Connection oriented output filters are now stored in the
6881 conn_rec instead of the request_rec. This allows us to add the
6882 output filter in the pre-connection phase instead of the
6883 post_read_request phase, which keeps us from trying to write an
6884 error page before we have a filter to write to the network.
6885 [Ryan Bloom, Jeff Trawick, and Greg Ames]
6887 *) Cleaning up an mmap bucket no longer deletes the mmap. An
6888 mmap can be used across multiple buckets (default_handler with
6889 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
6890 the mmap itself can't be associated with the bucket.
6893 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
6896 *) Radical surgery to improve mod_isapi support under Win32.
6897 Includes a number of newer ServerSupportFunction calls, support
6898 for ReadClient (in order to retrieve POSTs greater than 48KB),
6899 and general bug fixes to more reliably load ISAPI .dll's and
6900 prevent leaking handle resources. Note: There are still
6901 discrepancies between IIS's and Apache's ServerVariables, and
6902 async calls are still not supported. Additional warnings are
6903 logged to facilitate debugging of unsupported ISAPI calls.
6906 *) Add input filtering to Apache. The basic idea for the input
6907 filters is the same as the ideas for output filters. The biggest
6908 difference is that instead of calling ap_pass_brigade, ap_get_brigade
6909 should be called, and the order of execution for the filter itself is
6910 different. When writing an output filter, a brigade is passed in,
6911 and filters operate directly on that brigade, when done, they call
6912 ap_pass_brigade. Input filters are the exact opposite. Because input
6913 is not a push operation, filters first call ap_get_brigade. When this
6914 function returns, the input filter will be left with a valid brigade.
6915 The input filter should then operate on the brigade, and return.
6918 *) Fix building on BSD/OS using its native make. The build system
6919 falls back to the BSD .include directive on that host platform.
6922 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
6923 SHA1 and plaintext password encodings. Make feature tests a
6924 bit more flexible. [William Rowe]
6926 *) Charset translation: mod_charset_lite handles output content
6927 translation in a filter. mod_charset_lite no longer ignores
6928 subrequests. A bunch of cruft related to BUFF's support for
6929 translating request and response bodies was removed.
6932 *) Move the addition of the CORE filter to the post_read_request
6933 hook in http_core.c. This removes the need to add the filter in
6934 multiple places and allows for an SSL module to be added much
6935 simpler. [Ryan Bloom]
6937 *) SECURITY: CVE-2000-0913 (cve.mitre.org)
6938 Fix a security problem that affects certain configurations of
6939 mod_rewrite. If the result of a RewriteRule is a filename that
6940 contains expansion specifiers, especially regexp backreferences
6941 $0..$9 and %0..%9, then it may be possible for an attacker to
6942 access any file on the web server. [Tony Finch]
6944 *) Fix a bug where errors that are detected during early request parsing
6945 don't produce visible HTTP error messages at the browser, because
6946 the core_filter wasn't present. [Greg Ames]
6948 *) Provide apr_socklen_t as a portability aid.
6949 [Victor J. Orlikowski]
6951 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
6952 as well as a comment arg to the add, adduser and update cmds.
6953 update allows the user to clear or preserve pw/groups/comment.
6954 Fixed a bug in dbmmanage that prevented the check option from
6955 parsing a password followed by :group... text. Corrected the
6956 seed calcualation for Win32 systems, and added -lsdbm support.
6959 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
6962 *) Avoid a segfault when parsing .htaccess files. An
6963 uninitialized tree pointer was passed to ap_build_config().
6966 *) Change the way that inet_addr & inet_network are checked for
6967 in APR's configure process to allow BeOS BONE to correctly
6968 find them. With this change BeOS BONE now builds from source
6969 with no problems. [David Reid]
6971 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
6972 the end of the parameters to execve() was stored in the wrong
6973 location, overlaying the storage beyond the newargs[] array and
6974 also passing uninitialized storage to execve(), which would
6975 sometimes fail with EFAULT. [Jeff Trawick]
6977 *) Fix a bug parsing configuration file containers. With a sequence
6978 like this in the config file
6980 <IfModule mod_kilroy.c>
6983 <IfModule mod_lovejoy.c>
6988 the second container would be terminated at the blank line due to
6989 sediment in the buffer from reading the prior </IfModule> and an
6990 error message would be generated for the real </IfModule> for the
6991 second container. Also due to this problem, any two characters
6992 could be used for "</" in the close of a container.
6995 *) ap_add_filter prototype changed to remove the ctx pointer. The
6996 pointer still remains in the filter structure, but it can not be
6997 a part of the ap_add_filter prototype. The reason is that when
6998 the core uses AddFilter to add a filter to the stack it doesn't
6999 know how to allocate the ctx pointer, or even how much memory should
7000 be allocated. The filters will have to be responsible for allocating
7001 the ctx memory when they need it.
7004 *) Add an AddFilter directive. This directive takes a list of filters
7005 that should be activated for the requested resource.
7008 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
7009 some other platforms). [Jeff Trawick]
7011 *) Modify mod_include to be a filter. Currently, it has only been tested
7012 on actual files, but it should work for CGI scripts too.
7015 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
7016 writes. apr_flush() for Unix: handle interrupted writes.
7019 *) NameVirtualHost can now take "*" as an argument instead of
7020 an IP address. This allows you to create a purely name-based
7021 virtual hosting server that does not have any IP addresses in
7022 the configuration file and which ignores the local address
7023 of any connections. PR #5595, PR #4455 [Tony Finch]
7025 *) Fix some compile warnings in mod_mmap_static.c
7026 [Mike Abbott <mja sgi.com>]
7028 *) Fix chunking problem with CGI scripts. The general problem was that
7029 the CGI modules were adding an EOS bucket and then the core added an
7030 EOS bucket. The chunking filter finalizes the chunked response when it
7031 encounters an EOS bucket. Because two EOS buckets were sent, we
7032 finalized the response twice. The fix is to make sure we only send one
7033 EOS, by utilizing a flag in the request_rec.
7036 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
7037 and Win32. Previously, the first read from an apr_file_t set up via
7038 apr_put_os_file() would return a '\0'. [Jeff Trawick]
7040 *) Mod_cgid now creates a single element bucket brigade, with a pipe
7041 bucket, instead of using BUFF's and ap_r*.
7044 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
7045 [Mike Abbott <mja sgi.com>]
7047 *) Remove ap_bopenf from buff code. This required modifying the file_cache
7048 code to use APR file's directly instead of going through BUFFs.
7051 *) Fix compile break on some platforms for mod_mime_magic.c
7052 [John K. Sterling <sterling covalent.net>]
7054 *) Fix merging of AddDefaultCharset directive.
7055 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
7057 *) Minor revamp of the rlimit sections of code. We now test
7058 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
7059 is now "available" even if the platform doesn't support
7060 the rlimit family (it's just a noop though). [Jim Jagielski]
7062 *) Migrate the pre-selection of which MPM to use for specific
7063 platforms to hints.m4, which contains (or should contain)
7064 all platform specific "hints". [Jim Jagielski]
7066 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
7069 *) Add tables with non-string/binary values to APR.
7072 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
7075 *) Update PCRE to version 3.2. [Ryan Bloom]
7077 *) Change the way buckets' destroy functions are called so that
7078 they can be more directly used when changing the type of a
7079 bucket in place. [Tony Finch]
7081 *) Add generic support for reference-counting the resources used by
7082 buckets, and alter the HEAP and MMAP buckets to use it. Change
7083 the way buckets are initialised to support changing the type of
7084 buckets in place, and use it when setting aside TRANSIENT buckets.
7085 Change the implementation of TRANSIENT buckets so that it can be
7086 mostly shared with IMMORTAL buckets, which are now implemented.
7089 Changes with Apache 2.0a6
7091 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
7093 *) Add a chunking filter to Apache. This brings us one step closer
7094 to removing BUFF. [Ryan Bloom]
7096 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
7097 added to the stack is the last filter to be called. [Ryan Bloom]
7099 *) Apache 2.0 has been completely documented using Scandoc. The
7100 docs can be generated by running 'make docs'. [Ryan Bloom]
7102 *) Add filtered I/O to Apache. This is based on bucket brigades,
7103 Currently the buckets still use BUFF under the covers, but that
7104 should change quickly. The only currently written filter is the
7105 core filter which just calls ap_bwrite. [The Apache Group]
7107 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
7108 built with thread support. [Jeff Trawick]
7110 *) Abort configuration if --with-layout was specified and there's
7111 no layout definition file. [Ken Coar]
7113 *) Add support for '--with-port=n' option to configure. [Ken Coar]
7115 *) Add support for extension methods for the Allow response header
7116 field, and an API routine for accessing r->allowed and the
7117 list of extension methods in a unified manner. [Ken Coar]
7119 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
7120 [Rob Simonson <simo us.ibm.com>]
7122 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
7123 APACHE_XLATE builds. [Jeff Trawick]
7125 *) A configuration file parsing problem was fixed. When the
7126 configuration file started with an IfModule/IfDefine container,
7127 only the last statement in the container would be retained.
7130 Changes with Apache 2.0a5
7132 *) Perchild is serving pages after passing them to different child
7133 processes. There are still a lot of bugs, but this does work. I
7134 have made requests against the same installation of Apache, and had
7135 different servers use different user IDs to serve the responses.
7136 This change moves to using socketpair instead of an AF_UNIX socket.
7139 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
7140 It can't seem to pass between child processes yet, but I think we
7141 are closer now than before. This moves us back to using Unix
7142 Domain Sockets. [Ryan Bloom]
7144 *) libapr functions and types renamed with apr_ prefix.
7145 #include "apr_compat.h" for 1.3.x backwards compat
7148 *) Fix problems with APR sockaddr handling on Win32. It didn't always
7149 return the right information on the local socket address.
7150 [Gregory Nicholls <gnicholls level8.com>]
7152 *) ap_recv() on Win32: Set bytes-read to 0 on error.
7153 [Gregory Nicholls <gnicholls level8.com>]
7155 *) Add an option to not detach from the controlling terminal without
7156 going into single process mode. This allows for much easier
7157 debugging of the process startup code. [Ryan Bloom]
7159 *) ab: don't use perror() to report the failure of an APR function.
7162 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
7163 scoreboard on graceful restarts.
7166 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
7167 An invalid ap_proc_t was passed to ap_create_process().
7170 *) Allow modules to register filters. Those filters are still
7171 never called, but this is a step in the right direction.
7172 [Ryan Bloom and Greg Stein]
7174 *) Register the mod_cgid daemon process for cleanup so that it is
7175 killed at termination if it does not die when the parent gets
7176 SIGTERM. This change is to fix occasional problems where the
7177 process stays around. Bugs in similar logic in mod_rewrite and
7178 mod_include were also fixed. [Jeff Trawick]
7180 *) Fix a bug in the time handling. Basically, we were imploding a time
7181 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
7182 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
7183 uses those two fields to adjust the time value. Because of the HTTP
7184 spec, both of those values can be zero'ed out safely. This fixes
7185 the bug correctly. [Ryan Bloom]
7187 *) Fix a couple of place in the Windows code where the wrong error
7188 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
7190 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
7192 *) Added the APR_EOL_STR macro for platform dependent differences in
7193 logfiles and other raw text (such as all APR files). Fixes logfiles
7194 not terminated with cr/lf sequences in Win32. [William Rowe]
7196 *) Move all strings functions in APR to src/lib/apr/strings and create
7197 apr_strings.h for the prototypes. [Ryan Bloom]
7199 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
7200 to repeat the syscall until we stop getting EINTR. I noticed a
7201 related problem at termination (SIGTERM) on FreeBSD when using
7202 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
7203 implementation work properly with child init. Previously, ap_lock()
7204 was essentially a no-op because all children were using different
7205 locks and thus nobody ever blocked. [Jeff Trawick]
7207 *) The htdocs/ tree has been moved out of the CVS source tree into
7208 a separate area for easier development. This has NO EFFECT on
7209 end-users or Apache installations. [Ken Coar]
7211 *) Integrate the mod_dav module for WebDAV protocol handling. This
7212 adds the dav and dav_fs modules, the SDBM library, and additional
7213 XML handling utilities. [Greg Stein]
7215 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
7218 *) Update the lib/expat-lite/ library (bring forward changes from
7219 the Apache 1.3 repository). [Greg Stein]
7221 *) If sizeof(long long) == sizeof(long), then prefer long in APR
7222 configure.in. [Dave Hill <ddhill zk3.dec.com>]
7224 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
7225 machines where sendfile is detected, but nobody has written ap_sendfile.
7226 [Dave Hill <ddhill zk3.dec.com>]
7228 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
7230 *) ab would start up more connections than needed, then quit when the
7231 desired number were finished. Also fixed a logic error involving
7232 ab keepalives. [Victor J. Orlikowski]
7234 *) WinNT: Implement non-blocking pipes with timeouts to communicate
7235 with CGIs. Apache 2.0a4 had non-blocking pipes but without
7236 timeouts (i.e, if a timeout was specified, the pipe reverted to
7237 a full blocking pipe). Now the behaviour is more in line with
7238 Unix non-blocking pipes.
7241 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
7242 cache open file handles along with accept socket reuse enables
7243 Apache 2.0 to serve non-keepalive requests for static files at
7244 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
7245 and Apache 2.0 will serve almost 1200 rps on my system).
7248 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
7249 supports two config directives, mmapfile (same behavious as
7250 mod_mmap_static) and cachefile. Use the cachefile directive
7251 to cache open file handles. This directive only works on systems
7252 that have implemented the ap_sendfile API. cachefile works today
7253 on Windows NT, but has not been tested on any flavors of Unix.
7256 *) Cleanup the configuration. With the last few changes the
7257 configuration process automatically:
7258 inherits information about how to build from APR. Allowing
7259 APR to inform Apache that it should or should not use -ldl
7261 Detects which mod_cgi should be used mod_cgi or mod_cgid,
7262 based on the threading model
7264 Apache calls APR's configure process before finishing it's
7265 configuration processing, allowing for more information flow
7270 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
7271 with non-zero argument makes the socket non-blocking. BeOS and
7272 OS/2 already worked this way. [Jeff Trawick]
7274 *) ap_close() now calls ap_flush() for buffered files, so write
7275 operations work a whole lot better on buffered files.
7278 *) Fix error messages issued from MPMs which explain where to change
7279 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
7282 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
7283 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
7284 now the way that the blocking state of a pipe is manipulated.
7285 ap_block_pipe() is gone. [Jeff Trawick]
7287 *) Correct the problem where the only local host name that the IP stack
7288 can discover are 'undotted' private names. If no fully qualified
7289 domain name can be identified, the default ServerName will be set to
7290 the machine's IP address string. A warning is always provided if the
7291 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
7293 *) Repair problems with config file processing which caused segfault
7294 at init when virtual hosts were defined and which caused ServerName to
7295 be ignored when there was no valid DNS setup. [Jeff Trawick]
7297 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
7299 *) Add ap_sendfile implementation for AIX
7300 [Victor J. Orlikowski]
7302 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
7303 apr_network_io.h, and apr_thread_proc.h.
7304 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
7306 *) Bring the allocation and pool debugging code back into a working
7307 state. This will need to be tested as so far it's only been used on
7310 *) Change configuration command setup to be properly typesafe when in
7311 maintainer mode. Note that this requires a compiler that can initialise
7312 unions. [Ben Laurie]
7314 *) Turn on buffering for config file reads. Part of this was to
7315 repair buffered I/O support in Unix and implement buffered
7316 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
7318 *) Win32: Fix problem where UTC offset was not being set correctly
7319 in the access log. Problem reported on news group by Jerry Baker.
7322 *) Fix segfault when reporting this type of syntax error:
7323 "</container> without matching <container> section", where
7324 container is VirtualHost or Directory or whatever.
7327 *) SECURITY: CVE-2000-1204 (cve.mitre.org)
7328 Prevent the source code for CGIs from being revealed when
7329 using mod_vhost_alias and the CGI directory is under the document root
7330 and a user makes a request like http://www.example.com//cgi-bin/cgi
7331 as reported in <news:960999105.344321 ernani.logica.co.uk>
7334 *) Add support for the new Beos NetwOrking Environment (BONE)
7337 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
7338 final input char is incomplete; ap_bwrite_xlate() now handles
7339 incomplete final input chars. [Jeff Trawick]
7341 *) Yet another update to saferead/halfduplex stuff -- need to ensure
7342 that a bhalfduplex call occurs before logging or else DNS and
7343 such can delay the last packet of the response. [Dean Gaudet]
7345 *) Some syscall reduction in APR on unix -- don't seek when setting
7346 up an mmap; and don't fcntl() more than once per socket.
7349 *) When mod_cgid is started as root, the cgi daemon now switches
7350 to the configured User/Group (like other httpd processes)
7351 instead of continuing as root. [Jeff Trawick]
7353 *) The prefork MPM now uses an APR lock for the accept() mutex.
7354 It has not been getting a lock at all recently. httpd -V now
7355 displays APR's selection of the lock mechanism instead of the
7356 symbols previously respected by prefork. [Jeff Trawick]
7358 *) Change the mmap() feature test to check only for existence.
7359 The previous check required features not used by Apache.
7362 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
7363 sometimes mangled. The len parm to accept() was not
7364 initialized, leading sometimes to an endless loop of failed
7365 accept() calls on OS/390 and anywhere else that failed the call
7366 if the len was negative. Use <sys/un.h> for struct sockaddr_un
7367 instead of declaring it ourselves to fix a compilation problem
7368 on Solaris. [Jeff Trawick]
7370 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
7372 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
7374 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
7376 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
7377 initialization if ALLOC_DEBUG is defined; no known symptom
7378 otherwise. [Jeff Trawick]
7380 *) Fix typo in configure script when checking for mod_so. bash
7381 doesn't seem to have a problem but /bin/sh on Solaris does.
7382 Symptom: "./configure: test: unknown operator =="
7385 *) Rebind the Win32 NT and 9x services control into the MPM.
7386 All console, WinNT SCM and Win9x pseudo-service control code is
7387 now wrapped within the WinNT MPM.
7390 *) Make a copy of getenv("PATH") before storing for later use. Some
7391 getenv() implementations use the same storage for successive calls.
7392 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
7394 *) Server Tokens work in 2.0 again. This also propogates the change
7395 to allow just the product name in the server string using
7399 Changes with Apache 2.0a4
7401 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
7402 won't need to call it. [Greg Ames, Jeff Trawick]
7404 *) Move pre_config hook call to between configuration read and config
7405 tree walk. This allows all modules to implement pre_config hooks
7406 and know that they will be called at an appropriate time.
7409 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
7412 *) Add pre-config hooks back to all modules.
7415 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
7416 ContentDigest enabled and we can't/don't mmap the file.
7419 *) We now report the correct line number for syntax errors in config
7420 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
7422 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
7423 related bugs, and changed shmem/locking to use apr API. Shared-mem
7424 is currently disabled, however, because of problems with graceful
7425 restarts. [Ronald Tschalär]
7427 *) Fix corruption of IFS variable in --with-module= handling.
7428 Depending on the user's shell or customization thereof, there
7429 would be errors generating ap_config_auto.h later in the configure
7430 procedure. [Jeff Trawick]
7432 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
7433 isn't used (as in 1.3), except that on Unix it is now logged via
7434 ap_log_rerror() instead of by the child having STDERR_FILENO refer
7435 to the error log. [Greg Ames, Jeff Trawick]
7437 *) Add '-D' argument processing for run time configuration defines.
7440 *) Organize http_main.c as independent code, such that no code or
7441 global data is exported from it. WIN32 will dynamically link it
7442 to the server core, so this will prevent mutual dependency.
7445 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
7446 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
7449 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
7450 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
7452 *) Add mod_charset_lite for configuring character set translation.
7455 *) Add '-n' option to htpasswd to make it print its user:pw record
7456 on stdout rather than having to frob a text file. [Ken Coar]
7458 *) Fix saferead. Basically, we flush the output buffer if a read on the
7462 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
7463 a conversion is single-byte only. [Jeff Trawick]
7465 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
7466 the BeOS 5.0 documentation says that shutdown doesn't work yet.
7469 *) Fix some minor errors where pid was being manipulated as an int
7470 instead of the portable pid_t. [Roy Fielding]
7472 *) Fix some error log prints that were printing the pointer to a
7473 structure rather than the pid within the structure.
7474 [Jeff Trawick, Roy Fielding]
7476 *) ab: Fix a command-line processing bug; track bad headers in
7477 err_response; support reading headers up to 2K.
7478 [Ask Bjoern Hansen <ask valueclick.com>]
7480 *) Fix ap_resolve_env() so that it handles new function added in a prior
7481 alpha (see "Added the capability to do ${ENVVAR} constructs in the
7482 config file.") as well as the constructs used by mod_rewrite.
7483 [Paul Reder <rederpj raleigh.ibm.com>]
7485 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
7487 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
7488 APR to perform translation, instead of accessing the hard-coded tables
7489 in 1.3's ebcdic.c. [Jeff Trawick]
7491 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
7494 *) Add the ability to hook into the config file reading phase. Basically
7495 if a directive is specified EXEC_ON_READ, then when that directive is
7496 read from the config file, the assocaited function is executed. This
7497 should only be used for those directives that must muck with HOW the
7498 server INTERPRETS the config. This should not be used for directives
7499 that re-order or replace items in the config tree. Those changes should
7500 be made in the pre-config step.
7503 *) Add mod_example to the build system.
7506 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
7507 byte character sets. [Jeff Trawick]
7509 *) Pick up various EBCDIC fixes from 1.3 (from Martin
7510 Kraemer and Oliver Reh originally according to the change log).
7513 *) Fix a couple of problems in RFC1413 support (controlled by the
7514 IdentityCheck directive). Apache did not build the request string
7515 properly and more importantly Apache would loop forever if the
7516 would-be ident server dropped the connection before sending a
7517 properly terminated response. [Jeff Trawick]
7519 *) apxs works in 2.0.
7522 *) Reliable piped logs work in 2.0.
7525 *) Introduce a hash table implementation into APR to be used for
7526 replacing tables and other random data structures in Apache.
7529 *) Add some more error reporting to htpasswd in the case of problems
7530 generating or accessing the temporary file. Also, pass in a
7531 buffer if the implementation knows how to use it (i.e., if L_tmpnam
7532 is defined). [Ken Coar]
7534 *) Configure creates config.nice now containing your configure
7535 options. Syntax: ./config.nice [--more-options]
7538 *) Fix various return code problems in APR on Win32. For most of
7539 these, APR was returning APR_EEXIST instead of GetLastError()/
7540 WSAGetLastError(). [Jeff Trawick]
7542 *) Make piped logs work again in version 2.0
7545 *) Add VPATH support to UNIX build system of Apache and APR.
7548 *) Fix ap_tokenize_to_argv to respect the const arguments that are
7552 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
7553 Patch submitted to author.
7556 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
7557 /sbin in PATH on FreeBSD (all submitted to rse previously)
7560 *) Fix building Pthread-based MPMs on OpenBSD
7561 [Sascha Schumann] PR#26
7563 *) Fix ap_readdir() problem on systems where d_name[] field in
7564 struct dirent is declared with only one byte. (This problem only
7565 affected multithreaded builds.) This caused a segfault during
7566 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
7567 least). [Jeff Trawick]
7569 *) Fix some make-portability problems on at least Tru64, Irix
7571 [Sascha Schumann] PR#18, PR#39
7573 *) Add ap_sigwait() to support old-style sigwait() on systems
7574 like OS/390 and UnixWare.
7577 *) Add POSIX-thread flags for more platforms.
7580 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
7581 (on Unix, at least) to handle resolver errors. Fix a bug in
7582 the definition of APR_ENOMEM so that ap_strerror() can spit
7583 out the correct error message for it.
7586 Changes with Apache 2.0a3
7588 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
7591 *) API: *HOOK* macros now have an AP_ prefix
7594 *) Win32: Eliminate redundant calls to initialize winsock.
7595 [Tim Costello <timcostello ozemail.com.au>]
7597 *) Fix bugs initializing ungetchar for pipes.
7598 [Chia-liang Kao <clkao CirX.ORG>]
7600 *) The ab program in the src/support directory is now portable using
7604 *) Support directory is being compiled when the server is built
7607 *) The configure option --with-program-name has been added to allow
7608 developers to rename the executable at configure time. This also
7609 changes the name of the config files to match the executable's name.
7612 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
7613 containing version numbers. [Martin Pool]
7615 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
7616 Unix; access_log and error_log now created with these perms; non-
7617 Unix is unaffected [Jeff Trawick]
7619 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
7620 Replaced more magic numbers with MD5_DIGESTSIZE.
7621 [William Rowe, Roy Fielding]
7623 *) Win32: Get mod_auth_digest compiling and added to the Windows
7624 build environment. Not tested and I'd be suprised if it
7625 actually works. [Bill Stoddard]
7627 *) Revamp the Win32 make environment. Makefiles have been removed and
7628 Apache.dsw created to bring together all the pieces. Create new file
7629 os/win32/BaseAddr.ref to define module base addresses (to prevent
7630 dll relocation at start-up).
7631 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
7633 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
7634 of the \015, \012, and \015\012 constants with macros.
7637 *) Add ap_xlate_open() et al for translation of text between different
7638 character sets. The initial implementation requires iconv().
7641 *) More FAQs and answers from comp.infosystems.www.servers.unix.
7642 [Joshua Slive <slive finance.commerce.ubc.ca>]
7644 *) CGI output is being timed out now.
7647 *) Fix the problem with dieing quietly. dupfile now takes a pool which
7648 is used by the new apr file. There is no reason to create a new file
7649 with the same lifetime as the original file.
7652 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
7653 module base addresses. This will help shooting seg faults
7654 in the field. [William Rowe <wrowe lnd.com>]
7656 *) Update Apache on Windows documentation. Add new document
7657 describing how to compile Apache on Windows.
7658 [William Rowe <wrowe lnd.com>]
7660 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
7661 microseconds instead of seconds. Some storage leaks and other
7662 minor bugs in related code were fixed. [Jeff Trawick]
7664 *) Win32: First cut at getting mod_isapi working under 2.0
7665 [William Rowe <wrowe lnd.com>]
7667 *) First stab at getting mod_auth_digest working under 2.0
7668 quick change summary:
7669 - moved the random byte generation (ap_generate_random_bytes) into APR
7670 - now uses ap_time_t
7671 - compiles and runs on linux
7673 [Brian Martin <bmartin penguincomputing.com>]
7675 *) Win32: Move the space stripping of physical service names
7676 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
7677 unresolved symbol. Add dependency checking to the
7678 CreateService call to ensure TCPIP and AFP (winsock) is started
7680 [William Rowe <wrowe lnd.com>]
7682 *) Win32: Add code to perform latebinding on functions that may
7683 not exist on all levels of Windows where Apache runs. This
7684 is needed to allow Apache to start-up on Win95/98. All calls
7685 to non portable functions should be protected with
7686 ap_oslevel checks to prevent runtime segfaults.
7687 [William Rowe <wrowe lnd.com>]
7689 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
7691 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
7693 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
7694 This addresses PR 1623. Still need to address timing out runaway
7695 CGI scripts. [Bill Stoddard]
7697 *) Win32: Make ap_stat Windows 95/98 friendly
7698 [William Rowe <wrowe lnd.com>]
7700 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
7701 always fail. Need to initialise the dwOSVersionInfoSize member of the
7702 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
7705 The patch also enhances ap_get_oslevel (and the associated enum) to
7706 handle selected service packs for NT4, and adds recognition for
7707 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
7708 we can use ReadFileScatter and WriteFileGather in readwrite.c.
7709 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
7711 *) Get mod_rewrite building and running, and mod_status building for Win NT
7712 [Allan Edwards <ake raleigh.ibm.com>]
7714 *) Patch to port mod_auth_db to the 2.0 api and also to support
7715 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
7716 2.7.7. It should work with version 1 as well but I haven't tested it.
7717 [Brian Martin <bmartin penguincomputing.com>]
7719 *) Get APR DSO code working under Windows. Includes cross platform
7721 [<Tim.Costello BTFinancialgroup.com>]
7723 *) Fix some of the Windows APR time functions.
7726 *) FAQ changes related to tidying up historical documents on the web site.
7727 [Joshua Slive <slive finance.commerce.ubc.ca>]
7729 *) Move Windows DSO code into APR.
7732 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
7733 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
7734 at build time. At this point, the server will not compile on Windows because
7735 of the recent DSO commits. Fixing those next.
7736 [Bill Rowe & Bill Stoddard]
7738 *) Added error checking for file I/O APR routines.
7739 [Jon Travis <jtravis covalent.net>]
7741 *) APR: Don't use the values of resolver error codes for the
7742 corresponding APR error codes. On Unix and Win32, return the
7743 proper APR error code after a resolver error. [Jeff Trawick]
7745 Changes with Apache 2.0a2
7747 *) Renamed the executable back to httpd on all platforms other
7751 *) Allow BeOS to survive restarts, log properly and a few
7752 small things it had problems with due to the way it setup
7753 users and groups. [David Reid]
7755 *) Get mod_rewrite working with APR locks
7756 [Paul Reder <rederpj raleigh.ibm.com>]
7758 *) Actually remove the sempahore when the lock cleanup routine
7759 is called on BeOS. [David Reid]
7761 *) Clear hook registrations between reads of the config file.
7762 When DSOs are unloaded and re-loaded the old hook pointers may
7763 no longer be valid. This fix eliminates potential segfaults.
7764 [Allan Edwards <ake raleigh.ibm.com>]
7766 *) Fix a problem with Sigfunc not being defined or bypassed
7767 if sigaction() wasn't found. [Jim Jagielski]
7769 *) Fix the locking mechanism on BSD variants. They now use fcntl
7770 locks. This allows the server to start and serve pages.
7773 *) First cut at getting the Win32 installer to work
7774 [William Rowe <wrowe lnd.com>]
7776 *) Get htpasswd compiling under Windows
7777 [William Rowe <wrowe lnd.com>]
7779 *) Change the log message for a bind() failure to show the
7780 interface and port number. [Jeff Trawick]
7782 *) Import the documentation from 1.3.12 and bring parts of it
7783 up-to-date with respect to the changes that have occurred
7787 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
7788 now logged correctly on BeOS.
7791 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
7792 Makefile.win includes the same user interface as the old
7794 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
7796 *) Win32 exec now uses COMSPEC environment string for command
7797 shell path resolution.
7798 [William Rowe <wrowe lnd.com>] PR#3715
7800 *) Win32: ap_connect() was not returning correct error condition
7802 [Allen Prescott <allen clanprescott.com>]
7804 *) Win32: ap_open() was broken on Win9x because an NT-specific
7805 flag was passed to CreateFile. ap_puts() added an unnecessary
7807 [Jeff Trawick <trawick us.ibm.com>]
7809 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
7810 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
7811 confusing ee/et name and made all extensions language/dialect
7812 rather than country reflecting. Changed example files to
7813 explicit reflect the ISO charset and added a few common
7814 ones to the example config [dirkx]
7816 *) Extend external module capability. To use this, you call
7817 configure with --with-module=path/to/mod1,path/to/mod2,etc.
7820 *) Backported the various "default charset" fixes from 1.3.12,
7821 including the AddDefaultCharset directive. [Jim Jagielski]
7823 *) Added the capability to do ${ENVVAR} constructs in the
7824 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
7825 it does this on a line by line basis; i.e. if the envvar
7826 expands to something with spaces you have to protect it
7827 by adding quotes around it (Unless of course you expect it
7828 to contains more than one argument. Alternatively you
7829 can compile it on a per token basis; which is what people
7830 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
7831 hampers fancier hacks.
7832 [Dirk-Willem van Gulik]
7834 *) Changed the 'ErrorDocument' syntax in that it NO longer
7835 supports the asymetric
7837 ErrorDocument 301 "Some message
7839 Note the opening " quote, without a closing quote. It now
7840 has either the following syntaxes
7842 ErrorDocument XXX /local/uri
7843 ErrorDocument XXX http://valid/url
7844 ErrorDocument XXX "Some Message"
7846 The recognition heuristic is: if it has a space it
7847 is a message. If it has no spaces and starts with a /
7848 or is a valid URL then treat it that way. Otherwise it
7849 is assumed to be a message.
7851 This breaks backward compatibility but makes live a hell
7852 of a lot easier for GUI's and config file parsers.
7853 [Dirk-Willem van Gulik]
7855 *) Changed 'CacheNegotiatedDocs' from its present/not-present
7856 syntax into a 'on' or 'off' syntax. As it currently is the
7857 only non nesting token which uses NO_ARGS and thus is an
7858 absolute pain for any config interface automation. This
7859 breaks backward compatibility. [Dirk-Willem van Gulik]
7861 *) Add ability to add external modules to the build process. This is
7862 done with --with-module=/path/to/module. Modules can only be added
7863 as static modules at this point.
7866 Changes with Apache 2.0a1
7868 *) Fix FreeBSD 3.3 core dump.
7869 Basically, ap_initialize() needs to get called before
7870 create_process(), since create_process() passes op_on structure
7871 to semop() to get a lock, but op_on isn't initialized until
7872 ap_initialize() calls setup_lock(). Here is a slight
7873 rearrangement to main() which calls ap_initialize() earlier...
7874 [Jeff Trawick <trawick us.ibm.com>]
7876 *) Enable Apache to use sendfile/TransmitFile API
7877 [Bill Stoddard, David Reid, Paul Reder]
7879 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
7883 *) Make file I/O and network I/O writev/sendv APIs consistent.
7884 Eliminate use of ap_iovec_t and use Posix struct iovec.
7885 Use seperate variable on ap_writev to set the number of iovecs
7886 passed in and number of bytes written.
7889 *) Adapt file iol to use APR functions. Replaced ap_open_file()
7890 with ap_create_file_iol(). ap_create_file_iol() requires that
7891 the file be opened prior to the call using ap_open().
7894 *) Port mod_include and mod_cgi to 2.0
7895 [Paul Reder, Bill Stoddard]
7897 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
7898 bytes_read/bytes_written is always valid (never -1). Plus
7899 some fixes to buff.c to correct problems introduced by the
7900 errno => ap_status_t changes a while back. Plus a fix to
7901 chunked encoding introduced right at the beginning of 2.0.
7904 *) Revamped UNIX build system to use autoconf and libtool.
7905 [Manoj Kasichainula, Sascha Schumann]
7907 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
7909 *) SECURITY: More rigorous checking of Host: headers to fix security
7910 problems with mass name-based virtual hosting (whether using mod_rewrite
7911 or mod_vhost_alias).
7912 [Ben Hyde, Tony Finch]
7914 *) Add back support for UseCanonicalName in <Directory> containers.
7915 [Manoj Kasichainula]
7917 *) Added APLOG_STARTUP log type. This allows us to write an error
7918 message without any of the date and time information. As a part
7919 of this change, I also removed all of the calls to fprintf(stderr
7920 and replaced them with calls to ap_log_error using APLOG_STARTUP
7921 writing to stderr is no longer portable, because we don't direct
7922 stderr to the error log on all platforms.
7925 *) Convert error logging functions to take errno as an argument.
7926 This makes our error logs more portable, because some Windows API's
7927 don't set errno. This change allows us to still output a valid
7928 message on all of our platforms.
7931 *) mod_mime_magic runs in 2.0-dev now.
7932 [Paul Reder <rederpj raleigh.ibm.com>]
7934 *) sendfile has been added to APR.
7935 [John Zedlewski <zedlwski Princeton.EDU>]
7937 *) buff.c has been converted to no longer use errno.
7938 [Manoj Kasichainula]
7940 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
7941 interface adaption to APR functions did it. [Martin Kraemer]
7943 *) Support DSOs properly on 32-bit HP-UX 11.0
7944 [Dilip Khandekar <dilip cup.hp.com>]
7946 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
7947 [Ralf S. Engelschall]
7949 *) Cleaned APR build environment integration and bootstrap APR
7950 automatically for developers from src/Configure.
7951 [Ralf S. Engelschall]
7953 *) Fixed building of src/support/htpasswd.c
7954 [Ralf S. Engelschall]
7956 *) When generating the Location: header, mod_speling forgot
7957 to escape the spelling-fixed uri. (Forw-Port from 1.3)
7960 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
7962 *) Change all pools to APR contexts. This is the first step to
7963 incorporating APR into Apache. [Ryan Bloom]
7965 *) Move "handler not found" warning message to below the check
7966 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
7967 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
7969 *) Support line-continuation feature in config.option file and
7970 allow the loading of multiple option sections at once via
7971 ``--with-option=<section1>,<section2>,...''
7972 [Ralf S. Engelschall]
7974 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
7976 Changes with Apache MPM
7978 *) Use asynchronous AcceptEx() and a completion port to accept and
7979 dispatch connections to threads in Windows NT/2000.
7982 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
7985 *) Implement the APACI --with-option facility
7986 (per default used the config.option file).
7987 [Ralf S. Engelschall]
7989 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
7991 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
7992 Replace pre_connection module call with a register_hook call and
7993 implement pre_connection as a hook. The intent is that these hooks will
7994 be extended to allow Apache to be multi-protocol, and also to allow the
7995 calling order to be specified on a per-hook/per-module basis.
7998 *) Implement mpm_* methods as "modules". Each method gets its own
7999 subdir in src/modules (eg: src/modules/prefork). Selection
8000 of method uses Rule MPM_METHOD. [Jim Jagielski]
8002 *) Port the hybrid server from the apache-apr repository as
8003 mpm_mpmt_pthread. [Manoj Kasichainula]
8005 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
8006 amongst the unix MPMs.
8008 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
8009 signal handling for the new world order. [Dean Gaudet]
8011 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
8012 of alloc.c for now. [Dean Gaudet]
8014 *) Handle partial large writes correctly. [Ben Laurie]
8016 *) Eliminate conn_rec's pointer to server. All it knows is the base server
8017 based on IP/port. [Ben Laurie]
8019 *) Port a bunch of modules to the new module structure.
8020 ["Michael H. Voase" <mvoase midcoast.com.au>]
8022 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
8024 *) Basic restructuring to introduce the MPM concept; includes various
8025 changes to the module API... better described by
8026 docs/initial_blurb.txt. [Dean Gaudet]
8028 Changes with Apache pthreads
8030 *) New buff option added: BO_TIMEOUT. It describes the timeout for
8031 buff operations (generally over a network).
8032 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
8034 *) Created http_accept abstraction. Added 4 new functions (not exported):
8035 init_accept(), begin_accepting_requests(), get_request(),
8036 stop_accepting_requests() [Bill Stoddard]
8038 *) Fix to ap_rprintf call that allows mod_info to work properly.
8039 [James Morris <jmorris intercode.com.au>]
8041 *) user and ap_auth_type fields were moved from connection_rec to
8042 request_rec. [Ryan Bloom]
8044 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
8045 needed in a threaded server.
8047 *) Initial pthread implementation from from Dean's apache-nspr code.
8048 [Bill Stoddard, Ryan Bloom]
8051 Changes with Apache 1.3.9
8053 *) Remove bogus error message when a redirect doesn't set Location.
8054 Instead, use an empty string to avoid coredump if the error message
8055 was supposed to include a location. [Roy Fielding]
8057 *) Don't allow configure to include mod_auth_digest unless it is
8058 explicitly requested, even if the user asked for all modules.
8061 *) Translate module names to dll names for OS/2 so that they are no more
8062 than 8 characters long and have an extension of "dll" instead of "so".
8065 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
8066 Fix test-compile check to check for randbyte instead of trand32.
8067 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
8068 and tweak to make Amaya happier. [Ronald Tschalär]
8070 *) Ensure that the installed expat include files are world readable,
8071 just like the other header files. [Martin Kraemer]
8073 *) Fixed generated AddModule adjustments in APACI's `configure' script
8074 in order to allow (new) modules like mod_vhost_alias to be handled
8075 correctly (which was touched by the adjustments for mod_alias).
8076 [Ralf S. Engelschall]
8078 *) For binary builds, add -R flag to apachectl to work around the lack of
8079 an absolute path to the ./libexec directory where the libhttp.ep file
8080 is needed for SHARED_CORE architectures. [Randy Terbush]
8082 *) WIN32: Create the CGI script process as DETACHED. This may solve the
8083 problem observed by some Win95/98 users where they get CGI script
8084 output sent to the console. [Bill Stoddard]
8086 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
8087 routines are now called ap_base64* and are 'plain' (i.e., no
8088 pool access or anything clever). Inside util.c the routines acting
8089 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
8090 The oddly named ap_uuencode(), ap_uudecode() are kept around for
8091 now but deprecated. [dirkx]
8093 *) Clean up the base64 and SHA1 additions and make sure they are
8094 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
8095 files. [Roy Fielding]
8097 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
8098 checking. Allow compiling on VS 6.0. [Randy Terbush]
8100 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
8102 *) Use TestCompile to search for the truerand library (rather than blindly
8103 assuming its existence). If it is not found, complain (but do not
8104 exit - yet). [Martin Kraemer]
8106 *) We forgot to add the new exported function names to
8107 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
8109 *) Add description of -T command-line option to usage().
8110 [Ralf S. Engelschall]
8112 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
8113 searched only AFTER libap has been searched, because libap needs
8114 some symbols from libos. [Martin Kraemer]
8116 *) Fix conflict with original mod_digest related to the symbol of the
8117 module dispatch list (which has to be unique for DSO and follow the
8118 usual conventions for the installation procedure).
8119 [Ralf S. Engelschall]
8121 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
8122 for other platforms as well. [Martin Kraemer]
8124 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
8125 types by AP_LONG and replace reference to renamed variable 'ubuf'
8126 by 'buffer'. [Martin Kraemer]
8128 Changes with Apache 1.3.8 [not released]
8130 *) Flush the output buffer immediately after sending an error or redirect
8131 response, since the result may be needed by the client to abort a
8132 long data transfer or restart a series of pipelined requests.
8133 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
8135 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
8136 [Ian Turner <iant sequent.com>] PR#4735
8138 *) Local struct mmap in http_core.c conflicted with system structure
8139 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
8141 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
8142 [Ronald Tschalär <ronald innovation.ch>]
8144 *) Fix a memory leak where the module counts were getting messed
8145 up across restarts. [David Harris <dharris drh.net>]
8147 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
8148 properly in mod_access.
8149 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
8151 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
8152 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
8154 *) PORT: Support for compaq/tandem/com.
8155 [Michael Ottati <michael.ottati compaq.com>, dirkx]
8157 *) Added SHA1 password encryption support to easy migration from
8158 Netscape servers. See support/SHA1 for more information.
8159 Caused the separation of ap_md5.c into md5, sha1 and a general
8160 ap_checkpass.c with just a validate_passwd routine. Added a
8161 couple of flags to support/htpasswd. Some reuse of the to64()
8162 function; hence renamed to ap_to64().
8163 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
8165 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
8166 with ASCII/EBCDIC conversions in "ident" query.
8167 [David McCreedy <McCreedy us.ibm.com>]
8169 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
8170 Change "Power Macintosh" to Power* so if uname prints "Power Book"
8171 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
8173 *) Fix SIGSEGV on some systems because the Vary fix below included
8174 a call to table_do with a variable argument list that was not
8175 NULL terminated. Replaced with better implementation. [Roy Fielding]
8177 Changes with Apache 1.3.7 [not released]
8179 *) The "Vary" response header field is now sanitised right before
8180 the header is sent back to the client. Multiple "Vary" fields
8181 are combined, and duplicate tokens (e.g., "Vary: host, host" or
8182 "Vary: host, negotiate, host, accept-language") are reduced to
8183 single instances. This is a better solution than the force-no-vary
8184 one (which is still valid for clients that can't cope with Vary
8185 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
8187 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
8189 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
8190 least on Linux and FreeBSD for now.
8193 *) Win32: More apache -k restart work. Restarts are now honored
8194 immediately and connections in the listen queue are -not- lost.
8195 This is made possible by the use of the WSADuplicateSocket()
8196 call. The listeners are opened in the parent, duplicated, then
8197 the duplicates are passed to the child. The original listen sockets
8198 are not closed by the parent across a restart, thus the listen queue
8200 [Bill Stoddard <stoddard raleigh.ibm.com>]
8202 *) Fix handling of case when a client has sent "Expect: 100-continue"
8203 and we are going to respond with an error, but get stuck waiting to
8204 discard the body in the pointless hope of preserving the connection.
8205 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
8207 *) Fix 'configure' to work correctly with SysV-based versions of
8208 'tr' (consistent with Configure's use as well). [Jim Jagielski]
8210 *) apxs: Add "-S var=val" option which allows for override of CFG_*
8211 built-in values. Add "-e" option which works like -i but doesn't
8212 install the DSO; useful for editing httpd.conf with apxs. Fix
8213 editing code so that multiple invocations of apxs -a will not
8214 create duplicate LoadModule/AddModule entries; apxs can now be
8215 used to re- enable/disable a module. [Wilfredo Sanchez]
8217 *) Win32: Update the server to use Winsock 2. Specifically, link with
8218 ws2_32.lib rather than wsock32.lib. This gives us access to
8219 WSADuplcateSocket() in addition to some other enhanced comm APIs.
8220 Win 95 users may need to update their TCP/IP stack to pick up
8221 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
8222 [Bill Stoddard <stoddard raleigh.ibm.com>]
8224 *) Win32: Redirect CGI script stderr (script debug info) into the
8225 error.log when CGI scripts fail. This makes Apache on Win32
8226 behave more like Unix.
8227 [Bill Stoddard <stoddard raleigh.ibm.com>]
8229 *) Fixed `httpd' usage display: -D was missing.
8230 [Ralf S. Engelschall] PR#4614
8232 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
8233 [Ralf S. Engelschall] PR#4561, PR#4562
8235 *) OS/2: Fix problem with accept lock semaphores where server would die with
8236 "OS2SEM: Error 105 getting accept lock. Exiting!"
8237 [Brian Havard] PR#4505
8239 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
8240 [Randy Terbush <randy covalent.net>]
8242 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
8243 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
8245 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
8246 command potentially _is_ GCC. [Ralf S. Engelschall]
8248 *) Fix apxs build issues on AIX
8249 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
8251 *) DocumentRoot Checking: Under previous versions, when Apache
8252 first started up, it used to do a stat of each DocumentRoot to
8253 see if it existed and was a directory. If not, then an error
8254 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
8255 does not exist, you will get error messages in error_log. If
8256 the '-t' command line option is used (to check the configuration)
8257 the check of DocumentRoot IS performed. An additional command
8258 line option, '-T', has been added if you want to avoid the
8259 DocumentRoot check even when checking the configuration.
8262 *) Win32: The query switch "apache -S" didn't exit after showing the
8263 vhost settings. That was inconsistent with the other query functions.
8264 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
8266 *) Win32: Changed behaviour of apache -k restart.
8267 Previously, the server would drain all connections in the stack's
8268 listen queue before honoring the restart. On a busy server, this
8269 could take hours. Now, a restart is honored almost immediately.
8270 All connections in Apache's queues are handled but connections in
8271 the stack's listen queue are discarded. Restart triggered by
8272 MaxRequestPerChild is unchanged.
8273 [Bill Stoddard <stoddard raleigh.ibm.com>]
8275 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
8276 the accept loop. Good for a 5% performance boost. Cleaned up
8277 parent/child process management code.
8278 [Bill Stoddard <stoddard raleigh.ibm.com>]
8280 *) Added ceiling on file size for memory mapped files.
8281 [John Giannandrea <jg meer.net>] PR#4122
8283 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
8284 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
8285 [Henri Gomez <gomez slib.fr>, Ralf S. Engelschall]
8287 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
8288 use this at least for Expat. [Ralf S. Engelschall]
8290 *) Allow .module files to specify libraries with Lib:.
8293 *) Allow SetEnvIf[NoCase] to test environment variables as well
8294 as header fields and request attributes. [Ken Coar]
8296 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
8297 content-types are "text/html;parameters". PR#4524 [Ken Coar]
8299 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
8300 never accepted into any standard, and it opens up certain DoS
8301 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
8303 *) TestCompile updated. We can now run programs and output the
8304 results during the Configure process. [ Jim Jagielski]
8306 *) The source is now quad (long long) aware as needed. Specifically,
8307 the Configure process determines the correct size of off_t and
8308 *void. When the OS/platform/compiler supports quads, ap_snprintf()
8309 provides for the 'q' format qualifier (if quads are not available,
8310 'q' is silently "demoted" to long). [Jim Jagielski]
8312 *) When the username or password fed to htpasswd is too long, include the
8313 size limit in the error message. Also report illegal characters
8314 (currently only ':') in the username. Add the size restrictions
8315 to the man page. [Ken Coar]
8317 *) Fixed the configure --without-support option so it doesn't result in
8318 an infinite loop. [Marc Slemko]
8320 *) Piped error logs could cause a segfault if an error occured
8321 during configuration after a restart.
8322 [Aidan Cully <aidan panix.com>] PR#4456
8324 *) If a "Location" field was stored in r->err_headers_out rather
8325 than r->headers_out, redirect processing wouldn't find it and
8326 the server would core dump on ap_escape_html(NULL). Check both
8327 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
8328 if Location isn't set. [Doug MacEachern, Ken Coar]
8330 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
8331 of the Expat 1.0.2 distribution. [Greg Stein]
8333 *) Replace regexec() calls with calls to a new API stub function
8334 ap_regexec(). This solves problems with DSO modules which use the regex
8335 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]
8337 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
8338 environment variables can be set according to the protocol version
8339 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
8341 *) Add DSO support for OpenStep (Mach 4.2) platform.
8342 [Ralf S. Engelschall, Rex Dieter <rdieter math.unl.edu>] PR#3997
8344 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
8345 [Jan Gallo <gallo pvt.sk>] PR#3690, PR#4373
8347 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
8348 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
8350 *) Better DSO flags recognition on NetBSD platforms using ELF.
8351 [Todd Vierling <tv pobox.com>] PR#4310
8353 *) Always log months in english format for %t in mod_log_config.
8354 [Petr Lampa <lampa fee.vutbr.cz>] PR#4366, 679
8356 *) Support for server-parsed and multiview-determined ReadmeName and
8357 HeaderName files in mod_autoindex. Removed the restriction on
8358 "/"s in ReadmeName and HeaderName directives since the *sub_req*
8359 routines will deal with the access issues. (It's now possible to
8360 have {site|group|project|customer|...} wide readmes and headers.)
8361 [Raymond S Brand <rsbx rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
8364 *) When stat() fails, don't assume anything about the contents of
8365 the struct stat. [Ed Korthof <ed bitmechanic.com>]
8367 *) It's OK for a semop to return EINTR, just loop around and try
8368 again. [Dean Gaudet]
8370 *) Fix configuration engine re-entrant hangups, which solve a
8371 handful of problems seen with mod_perl <Perl> configuration sections
8372 [Salvador Ortiz Garcia <sog msg.com.mx>]
8374 *) Mac OS and Mac OS X Server now use the appropriate custom layout
8375 by default when building with APACI; allow for platform-specific
8376 variable defaults in configure. [Wilfredo Sanchez]
8378 *) Do setgid() before initgroups() in http_main; some platforms
8379 zap the grouplist when setgid() is called. This was fixed in
8380 suexec earlier, but the main httpd code missed the change.
8381 [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2579
8383 *) Add recognition of .tgz as a gzipped tarchive.
8384 [Bertrand de Singly <bertrand.de-singly polytechnique.fr>] PR#2364
8386 *) mod_include's fsize/flastmod should allow only relative paths, just
8387 like "include file". [Jaroslav Benkovsky <benkovsk pha.pvt.cz>]
8389 *) OS/2: Add support for building loadable modules using DLLs.
8392 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
8395 *) Fix minor but annoying bug with the test for Configuration.tmpl
8396 being newer than Configuration so that it is less likely to fail
8397 when using APACI and shadow sources. [Wilfredo Sanchez]
8399 *) PORT: Add initial support for Mac OS (versions 10.0 and
8400 greater). Use Mac OS X Server layout for now. Clean up dyld code
8401 in unix/os.c, and don't install the dyld error handlers, which
8402 are no longer needed in Mac OS. [Wilfredo Sanchez]
8404 *) Rename Rhapsody layout to "Mac OS X Server". Change install
8405 locations to appropriate ones for user-built (as opposed to
8406 system) installs. [Wilfredo Sanchez]
8408 *) Modify mod_autoindex's handling of AddDescription so that the
8409 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
8411 *) Add functionality to the install-bindist.sh script created by
8412 binbuild.sh to use tar when copying distribution files to the
8413 serverroot. This allows upgrading an existing installation
8414 without nesting the new distribution in the old.
8416 install-bindist.sh now detects the local perl5 path to install
8417 apxs and dbmmanage with proper path to perl interpreter.
8419 Add an install-binsupport target which copies the source files
8420 for apxs and dbmmanage to bindist to allow these scripts to
8421 be properly installed relative to the destination serverroot.
8422 [Randy Terbush, Covalent Technologies, <randy covalent.net>]
8424 *) Fix intermittent SEGV in ap_proxy_cache_error() in
8425 src/modules/proxy_util.c where a NULL filepointer and
8426 temporary filename were closed and unlinked.
8427 [Graham Leggett <minfrin sharp.fm>,

8430 *) Fix inconsistent error messages reported by mod_proxy.
8431 [Graham Leggett <minfrin sharp.fm>]
8433 *) OS/2: Fix terminating CGIs that aren't compiled by EMX GCC when a
8434 connection is aborted. [Brian Havard]
8436 *) Force the LANG envariable to the known state of "C" so that we
8437 have assurance about how string manipulators (e.g., tr) will
8438 function. [Ken Coar] PR#1630
8440 *) Add a directive to allow customising of the tracking cookie name.
8441 [Ken Coar] PR#2921, 4303
8443 *) Add "force-no-vary" envariable to allow servers to work around
8444 clients that choke on "Vary" fields in the response header.
8445 [Ken Coar, Dmitry Khrustalev <dima zippy.machaon.ru>] PR#4118
8447 *) Fixed a bug in mod_dir that causes a child process will infinitely
8448 recurse when it attemps to handle a request for a directory wnd the
8449 value of the DirectoryIndex directive is a single dot. Also likely
8450 to happen for anyother values of DirectoryIndex that will map back

8461 *) Add "opt" (SysV-style) layout to config.layout. [Raymond S Brand
8464 *) Add APACI --without-execstrip option which can be used to disable the
8465 stripping of executables on installation. This is very important for DSO
8466 and debugging situations. [Ralf S. Engelschall]
8468 *) Add support for OS/2 (case insenstive filesystem, .exe suffix, etc)

8534 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
8537 *) Correct an apparent typo: on the Windows and MPE platforms, the
8538 htpasswd utility was limiting passwords to only 8 characters.
8541 *) EBCDIC platforms: David submitted patches for two bugs in the
8542 MD5 digest port for EBCDIC machines:
8543 a) the htdigest utility overwrote the old contents of the digest file
8544 b) the Content-MD5 header value (ContentDigest directive) was wrong
8545 when the returned file was not converted from EBCDIC, but was a
8546 binary (e.g., image file) in the first place.
8547 [David McCreedy <mccreedy us.ibm.com>]
8549 *) support/htpasswd now permits the password to be specified on the
8550 command line with the '-b' switch. This is useful when passwords
8551 need to be maintained by scripts -- particularly in the Win32
8552 environment. [Ken Coar]
8554 *) Win32: Win32 multiple services patch. Added capability to install and
8555 run multiple copies of apache as individual services.
8558 apache -n apache1 -i -f c:/httpd.conf
8559 Installs apache as service 'apache1' and associates c:/httpd.conf
8562 Starts apache1 service.

8584 *) Correct the signed/unsigned character handling for the MD5 routines;
8585 mismatches were causing compilation problems with gcc -pedantic and
8586 in the TPF cross-compilation. [Ken Coar]
8588 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
8589 a roughly 5 fold speed up. [Brian Havard]
8591 *) proxy ftp: instead of using the hardwired string "text/plain" as
8592 a fallback type for files served by the ftp proxy, use the
8593 ap_default_type() function to determine the configured type.
8594 This allows for special configurations like
8595 <Directory proxy:ftp://some.host>
8596 DefaultType gargle/blurb
8598 Additionally, add the Content-Encoding: header to FTP proxy replies
8599 when the encoding is defined (by the AddEncoding directive).
8600 Because it was missing, it was almost impossible to browse compressed
8601 files using the FTP proxy (works now perfectly in Communicator).
8602 The ftp proxy now also returns the Date: and Server: header lines (if not
8603 much else... This code is "somewhat" broken) like normal requests do.
8606 *) Be more smart in APACI's configure script when determining the UID/GID
8607 for User/Group directives and use the determined UID/GID to initialize
8608 the permissions on the proxycachedir.
8609 [Dirk-Willem van Gulik, Ralf S. Engelschall]
8611 *) Changed the forking-prior-to-cleanup in the proxy module to first
8612 check wether it actually needs to collect garbage. This reduces
8613 the number of fork()s from one/request to just the odd one an hour.
8614 [Dirk-Willem van Gulik]

8624 [Randy Terbush, Covalent Technologies]
8626 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
8627 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf

8643 *) M_INVALID needed a value within the scope of METHODS so that unknown
8644 methods can be access controlled. [Roy Fielding] PR#3821
8646 *) Added PassAllEnv; makes server's entire environment available
8647 to CGIs and SSIs executed within directive's scope. [Ken Coar]
8649 *) ap_uuencode() always added two trailing '='s and encoding of
8650 8 bit characters on a machine with signed char may produced
8651 incorrect results. Additionally ap_uuencode() should now
8652 work correctly on EBCDIC platforms.
8653 [Ronald Tschalär <ronald innovation.ch>] PR#3411
8655 *) WIN32: Binary installer now runs the configuration DLL before
8656 the reboot prompt (which is only given if MSVCRT.DLL system
8657 DLL is new or updated). This should avoid the configuration
8658 directory being empty after installation. [Paul Sutton]

8665 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
8667 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
8668 have been reported with flock() locking (probably related to kernel
8669 version). [Dean Gaudet] PR#2723, 3531

8682 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
8683 for 8-bit safeness. [Dean Gaudet]
8685 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
8686 because SPARCs have a small machine-specific maximum size for the Global
8687 Offset Table which is often exceeded when compiling one of the larger
8688 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977
8690 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

8707 *) Let APACI's configure script correctly complain for unknown --enable-XXX
8708 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
8710 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
8711 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
8712 possible buffer overflows. [Ralf S. Engelschall]
8714 *) Remove no longer used non-API function ap_single_module_init().
8715 [Ralf S. Engelschall]
8717 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
8720 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
8721 to make platform installations easier. [Wilfredo Sanchez]
8723 *) In configure, do not append the target name to the directory path if
8724 the path already contains "apache". [Ralf S. Engelschall]
8726 *) SIGPIPE is now ignored by the server core. The request write routines
8727 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
8728 correctly check for output errors and mark the connection as aborted.
8729 Replaced many direct (unchecked) calls to ap_b* routines with the
8730 analogous ap_r* calls. [Roy Fielding]
8732 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
8733 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
8734 Furthermore map lookups for non-existent keys are now cached as well.
8735 Additionally "txt" maps are now parsed with simple string functions
8736 instead of using ap_pregcomp(). As a side effect a bug that prevented
8737 the usage of keys containing the "," character was fixed.
8738 The changes drastically improve the performance when large rewrite maps
8740 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
8742 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
8743 other than GET, and const'd the definition of method in request_rec.
8746 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
8748 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
8749 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
8751 *) Add %V to mod_log_config, this logs the hostname according to the
8752 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
8753 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
8755 *) Add support for \n and \t to mod_log_config, can be used to produce
8756 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
8758 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
8760 *) Added informative error messages for failed munmap() and fseek() calls
8761 in http_core.c. [John Bley, Roy Fielding]
8763 *) Added some informative error messages for some failed malloc()
8764 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
8766 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
8767 is removed. This allows <Directory proxy:*> directives to work and
8768 prevents invalid requests from killing the process.
8769 [Brian Havard <brianh kheldar.apana.org.au>]
8771 *) Reorganised FAQ document.
8772 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497
8774 *) src/support/: The ApacheBench benchmark program was overhauled by
8775 David N. Welton: you can now have it generate an HTML TABLE, presumably
8776 for integration into other HTML sources. David updated the ab man page
8777 as well and added some missing descriptions. Thanks!
8778 [David N. Welton <davidw prosa.it>]
8780 *) Win32: The filename validity checker now allows filenames containing
8781 characters in the range 0x80 to 0xff (for example accented characters).
8782 [Paul Sutton] PR#3890
8784 *) Added conditional logging based upon environment variables to
8785 mod_log_config. mod_log_referer and mod_log_agent
8786 are now deprecated. [Ken Coar]
8788 *) Allow apache acting as a proxy server to relay the real
8789 reason of a failure to a client rather than the "internal
8790 server error" it does currently. The general exposure mechanism
8791 can be triggered by any module by setting the "verbose-error-to"
8792 note to "*"; this allows more than just proxy errors to be exposed.
8793 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
8795 *) Moved man pages for ab and apachectrl to section 8.
8796 [Wilfredo Sanchez, Roy Fielding]
8798 *) Added -S option to install.sh so that options can be passed to
8799 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
8801 *) Tweak modules Makefile generated by Configure so that it handles
8802 the test case of no modules being selected. [<chaz reliant.com>]
8804 *) Added a <LimitExcept method ...> sectioning directive that allows
8805 the user to assign authentication control to any HTTP method that
8806 is *not* given in the argument list; i.e., the logical negation
8807 of the <Limit> directive. This is particularly useful for controlling
8808 access on methods unknown to the Apache core, but perhaps known by
8809 some module or CGI script. [Roy Fielding, Tony Finch]
8811 *) Prevent apachectl from complaining if the PIDFILE exists but
8812 does not contain a process id, as might occur if the server is
8813 being rapidly restarted. [Wilfredo Sanchez]
8815 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
8817 *) Entity tag comparisons for If-Match and If-None-Match were not being
8818 performed correctly -- weak tags might cause false positives. Also,
8819 strong comparison wasn't properly enforced in all cases.
8820 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
8822 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
8825 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
8826 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
8828 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
8829 to util.c for parsing an HTTP header field value to extract the next
8830 list item, taking into account the possible presence of nested comments,
8831 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
8832 insignificant whitespace and lowercases non-quoted tokens.
8833 [Roy Fielding] PR#2065
8835 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
8836 code different from 500. This allows the proxy to, e.g., return
8837 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
8839 *) Fix ordering of language variants for the case where the traditional
8840 negotiation algorithm is being used with multiple language variants
8841 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
8843 *) Do not round the TCN quality calculation to 5 decimal places,
8844 unlike RFC 2296, because the calculation might need 12 decimal places
8845 to get the right result. [Roy Fielding]
8847 *) Remove unused code to disable transparent negotiation when
8848 negotiating on encoding only, as we now handle encoding too
8849 (though this is nonstandard for TCN), remove charset=ISO-8859-1
8850 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
8851 some debugging statements within mod_negotiation. [Koen Holtman]
8853 *) Fixed a rare memory corruption possibility in mod_dir if the index
8854 file is negotiable and no acceptable variant can be found.
8855 [Dean Gaudet, Roy Fielding, Martin Kraemer]
8857 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
8858 searching the Win32 registry for script interpreters.
8861 *) Win32: The compiled-in default filename for the error log is now
8862 error.log, which matches the default in the distributed httpd.conf.
8865 *) Win32: Any error messages from -i or -u command line options are now
8866 displayed on the console output rather than sent to the error log.
8867 Also the "Running Apache..." message is not output unless Apache is
8868 going to serve requests. [Paul Sutton]
8870 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
8871 and use a private significator ('$apr1$') to mark passwords as
8872 being smashed with our own algorithm. Also abstract the password
8873 checking into a new ap_validate_password() routine. [Ken Coar]
8875 *) Win32: The filename validity checker now allows "COM" but refuses
8876 access to "COM1" through "COM4". This allows filenames such
8877 as "com.name" to be served. [Paul Sutton] PR#3769.
8879 *) BS2000: Adapt to the new ufork() system call interface which will
8880 make subtasking easier on the OSD/POSIX mainframe environment.
8883 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
8884 ap_compat.h. [David White <david persimmon.com>] PR#3725
8886 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
8887 use `.db' instead of `.pag' not only for FreeBSD, but also when
8888 the NDBM library looks like Berkeley-DB based.
8889 [Ralf S. Engelschall] PR#3773

8892 [Ryan Bloom <rbb Raleigh.IBM.Com>]
8894 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
8896 *) SECURITY: Avoid some buffer overflow problems when escaping
8897 quoted strings. (This overflow was on the heap and we believe
8898 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
8900 *) Let src/Configure be aware of CFLAGS options starting with plus
8901 signs as it's the case for the HP/UX compiler.
8902 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
8904 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
8905 and check to see if the tar we wind up with supports '-h'.
8906 [Jim Jagielski] PR#3671
8908 *) A consistent and conservative style for all shell scripts has been
8909 implemented. Basically, all shell string tests use the traditional
8910 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
8911 to protect against bare null variable strings (ie: wrapping both
8912 sides with double quotes and prepending 'x'). 'x' was chosen
8913 because it's more universal and hopefully easier for old shell
8914 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
8917 *) The status module now prints out both the main server generation as
8918 well as the generation of each process. Also, the vhost info is
8919 printed with '?notable'. [Jim Jagielski]
8921 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
8922 and this makes its functions available to things in src/support.
8925 Changes with Apache 1.3.4
8927 *) Renamed macros status_drops_connection to ap_status_drops_connection
8928 and vestigial scan_script_header to ap_scan_script_header_err,
8929 mostly for aesthetic reasons. [Roy Fielding]
8931 *) The query switch "httpd -S" didn't exit after showing the
8932 vhost settings. That was inconsistent with the other query functions.
8935 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
8936 filename to the end of the STANDARD_MODULE_STUFF. Its
8937 presence at the beginning prevented reporting of the filename
8938 for modules compiled before 1 January 1999. [Ken Coar]
8940 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
8941 to detect and prevent access to special DOS device file names.
8942 [Paul Sutton, Ken Parzygnat]
8944 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
8945 and Makefile_win32_debug.txt (debug build) that work on Win95.
8946 Run each of the following from the src directory:
8947 nmake /f Makefile_win32.txt # compiles normal build
8948 nmake /f Makefile_win32.txt install # compiles and installs
8949 nmake /f Makefile_win32.txt clean # removes compiled junk
8950 nmake /f Makefile_win32_debug.txt # compiles debug build
8951 nmake /f Makefile_win32_debug.txt install
8952 nmake /f Makefile_win32_debug.txt clean
8955 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
8956 to build binary distributions. [Lars Eilebrecht]
8958 *) IndexOptions SuppressColumnSorting only turned off making
8959 the column headers anchors; you could still change the display
8960 order by manually adding a '?N=A' or similar query string to the
8961 URL. Now SuppressColumnSorting locks in the sort order so
8962 it can't be overridden this way. [Ken Coar]
8964 *) Added IndexOrderDefault directive to supply a default sort order
8965 for FancyIndexed directory listings. [Ken Coar] PR#1699
8967 *) Change the ap_assert macro to a variant that works on all platforms.
8968 [Richard Prinz <richard.prinz cso.net>] PR#2575
8970 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
8971 search for an underscore on dlsym() (as it's already the case
8972 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
8974 *) Small fix for mod_env.html: The module was documented as to be _not_
8975 compiled into Apache per default, although it _IS_ compiled into
8976 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
8978 *) Instead of fixing a bug in the generation procedure for config.status (a
8979 backslash was missing) we remove the bug together with it's complete
8980 context because the special cases of the past can now no longer occur
8981 because of the recent magic for the --with-layout default.
8982 [Ralf S. Engelschall] PR#3590
8984 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
8985 making sure the src/support/ tools are _forced_ to be build last (they
8986 depend on other libraries).
8987 [Markus Theissinger <markus.theissinger gmx.de>]
8989 *) Fix installation procedure: Now that os-inline.c is actually used (a
8990 recently fixed bug prevented this) we need to also install os-include.c
8991 in addition to os.h into the PREFIX/include/ location or building of
8992 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
8994 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
8995 allow us to distinguish between a garbled DSO (or even a file which isn't
8996 an Apache module DSO at all) and a DSO which doesn't match the current
8997 Apache API. [Ralf S. Engelschall] PR#3152
8999 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
9000 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
9001 match case insensitive (this especially avoids nasty patterns like
9002 `[tT][eE][sS][tT]'). Second two additional internal map functions
9003 `escape' and `unescape' were added which can be used to escape/unescape
9004 to/from hex-encodings in URLs parts (this is especially useful in
9005 combination with map lookups).
9006 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
9008 *) Renamed the macro escape_uri() to ap_escape_uri() which was
9009 forgotten (because it was a macro) in the symbol renaming process.
9010 [Ralf S. Engelschall]
9012 *) Fix some inconsistencies related to the scopes of directives. The only
9013 user visible change is that the directives `UseCanonicalName' and
9014 `ContentDigest' now use the (more correct) `Options' scope instead of
9015 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
9017 *) Using DSO, the Server token was being mangled. Specifically, the
9018 module's token was being added first before the Apache token. This
9019 has been fixed. [Jim Jagielski]
9021 *) Major overhaul of mod_negotiation.c, part 2.
9022 - properly handle "identity" within Accept-Encoding.
9023 - allow encoded variants in RVSA negotiation and let them appear in
9024 the Alternates field using the non-standard "encoding" tag-list.
9025 - fixed both negotiation algorithms so that an explicitly accepted
9026 encoding is preferred over no encoding if "identity" is not
9027 included within Accept-Encoding.
9028 - added ap_array_pstrcat() to alloc.c for efficient concatenation
9029 of large substring sequences.
9030 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
9033 *) Major overhaul of mod_negotiation.c, part 1.
9034 - cleanups to mod_negotiation comments and code structure
9035 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
9036 support for everything in the upcoming HTTP/1.1
9037 revision (draft-ietf-http-v11-spec-rev-06.txt).
9038 - language tag matching also handles tags with more than 2
9040 - empty Accept, Accept-Language, Accept-Charset headers are
9041 processed correctly; previously an empty header would make all
9042 values acceptable instead of unacceptable.
9043 - allowed for q values in Accept-Encoding
9044 - added support for transparent content negotiation (rfc2295 and
9045 rfc2296) (though we do not implement all features in these drafts,
9046 e.g. no feature negotiation). Removed old experimental version.
9047 - implemented 'structured entity tags' for better cache correctness
9048 (structured entity tags ensure that caches which can deal with Vary
9049 will (eventually) be updated if the set of variants on the server
9051 - this involved adding a vlist_validator element to request_rec
9052 - this involved adding the ap_make_etag() function to the global API
9053 - modified guessing of charsets used by Apache negotiation algorithm
9054 to guess 'no charset' if the variant is not a text/* type
9055 - added code to sort multiviews variants into a canonical order so that
9056 negotiation results are consistent across backup/restores and mirrors
9057 - removed possibility of a type map file resolving to another type map
9058 file as its best variant

9083 Now SHELL_PATH is started in these cases. [Martin Kraemer]
9085 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
9088 *) Update APXS manual page: some -q option arguments were missing
9089 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
9091 *) Cleanup the command line options: `-?' was documented to show
9092 the usage list but does it with an error because `?' is not a valid
9093 command. OTOH a lot of users expect `-h' to print such a usage list and
9094 instead are annoyed for ages by our huge unreadable list of directives.
9095 So we now changed the command line options this way:
9097 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
9098 very similar to the popular linker option.
9100 Intent: while -l gives the small list of modules, -L now gives the
9101 large list of directives implemented by these modules. This is also
9102 consistent with -v (short version info) and -V (large version info).
9104 Intent: it's now the expected option ;-)
9105 The manual page was adjusted accordingly.

9108 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
9109 wasn't defined. [Rick Franchuk <rickf transpect.net>]
9111 *) Removed recently introduced bugs and disfigurements in APACI:
9112 o fixed argument line processing: using $args was broken: It was not
9113 initialized and using args="$args $apc_option" and even args="$args
9114 \"$apc_option\"" fails in the second processing round for any arguments
9115 containing whitespaces. The only correct way is to use the construct
9116 "$@" (but not possible here) or iterate _both_ times over the implicit
9117 argument line (no argument to for-loop) which is what we now use.
9118 o make --with-layout=Apache the default without creating
9119 redundancy (copying the --with-layout block in the argument parsing
9120 loop). We achieve this by using the "$@" construct together with the
9121 `set' command to prepend --with-layout=Apache to the command line in
9122 case --with-layout is not used.
9123 o fixed auto-suffix handling now that config.layout exists.
9124 Paths which are auto-suffixed are marked with a trailing plus sign in
9125 config.layout and every path now can be marked this way (not only the
9126 four paths for which we do it currently). Additionally the suffix is
9127 no longer a static one. Instead it's now `/<target>' where <target> is
9128 the argument of the --target option or per default `httpd'.
9129 o allow also tabs (and only spaces) where we match whitespaces
9130 o various fixes and cleanups related to used shell coding style
9131 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
9132 o trimmed output of --help to fit into 80 columns

9157 *) Make generation of src/Configuration.apaci more robust: It failed to
9158 differenciate between modules when one module name was a postfix of
9159 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
9160 just XXX (think about totally non-standard names like "apache_ssl", too).

9194 *) Fixed possible (but harmless in practice) bug in the DBM lookup
9195 procedure of mod_rewrite: very long keys were truncated.
9196 [Ralf S. Engelschall]
9198 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
9199 identifier, currently "Apache" and "GNU" are pre-defined in the file
9200 config.layout. Custom layouts are possible by using FILE:ID as the
9201 argument where the layout ID is taken from FILE.
9203 The config.layout file consists of <Layout ID>..</Layout> sections
9204 where inside those sections "path_variable: path_value" pairs can be
9205 specified. These lines are converted to path_variable='path_value'.
9207 *) Add a DefaultLanguage directive so that files missing a language
9208 extension (e.g., .fr, .de) can be labelled as being some other
9209 default language. DefaultLanguage can appear in <Directory> and
9210 <Files> containers as well as .htaccess files. [Paul Sutton]
9213 *) Fix TARGET configuration when configuring and installing using
9214 APACI configure. TARGET now defines the basename of the configuration

9555 *) Fix the recently introduced C header file checking: We now use the C
9556 pre-processor pass only (and no longer the complete compiler pass) to
9557 determine whether a C header file exists or not. Because only this way
9558 we're safe against inter-header dependencies (which caused horrible
9559 portability problems). The only drawback is that we now have a CPP
9560 configuration variable which has to be determined first (we do a similar
9561 approach as GNU Autoconf does here). When all fails the user still has
9562 the possibility to override it manually via APACI or src/Configuration.
9563 As a fallback for the header check itself we can directly check the
9564 existance of the file under /usr/include, too.

9612 directive allows the configuration of the ports to which a
9613 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
9615 *) mod_expires will now act on content that is not sent from a file
9616 on disk. Previously it would never add an Expires: header to
9617 any response that did not come from a file on disk; the only
9618 case where it still doesn't (and can't) add one for that type of
9619 content is if you are using a modification date based setting.

9634 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
9635 a common problem of (mis-administrated?) IIS servers, make the apache
9636 proxy immune to these errors (and ignore the duplicates, but log
9637 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
9639 *) The <IfModule and <IfDefine block starting directives now only
9640 allow exactly one argument. Previously, the optional negation
9641 character '!' could be separated by whitespace without a syntax
9642 error being reported, albeit defeating the IfModule functionality
9643 (enclosed directives would ALWAYS be executed). By using the
9644 stricter syntax, these hard-to-track errors can be avoided.
9647 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
9648 cause the standalone FancyIndexing directive to logically OR
9649 into any existing IndexOptions settings rather than wiping
9650 them out. [Ken Coar]
9652 *) Changes in ftp proxy: make URL parsing simpler by using the
9654 + Add display of the "current directory" in cases where it's
9655 different from the supplied path (e.g., ftp://user@host/ lives
9656 in /home/user, not in /, therefore clicking on "../" in the
9657 starting directory might send us to /home/).
9658 + When ftp login fails, (esp. when a user name was part of the
9659 URL already), we now return [401 Unauthorized ] to allow the
9660 browser to pop up an authorization dialog. This makes passwords
9661 slightly less visible (they don't appear in the regular log files)
9662 and implements a functionality that other www proxy servers
9666 *) Triggered by the recent "Via:" header changes, the proxy module would
9667 dump core for replies with invalid headers (e.g., duplicate
9668 "HTTP/1.0 200 OK" lines). These errors are now logged and the
9669 core dump is avoided. Also, broken replies are not cached.

9677 [Yves Arrouye <yves apple.com>] PR#2866
9679 *) Replace the inlined information grabbing stuff for the configuration
9680 adjustment feature (no --without-confadjust) with calls to a new helper
9681 script `buildinfo.sh' which is both more flexible and already proofed to
9682 be more robust against platform differences. This mainly fixes the
9683 recently occured ``sed: command garbled: ...'' problems.

9704 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
9705 5 to 10 because there are some users out there who always have 5 to 8
9706 variables in one RewriteRule and had to patch mod_rewrite.h for every
9707 release. So 15 should be now more than enough, even for them. (I never
9708 needed more than 4 in my RewriteRules ;-)

9711 *) Make the proxy generate and understand Via: headers

9715 the header lines. [Martin Kraemer]
9717 *) Make sure the config.status file is not overridden when just
9718 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
9720 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
9721 provide a way to trace API changes that add functionality but do
9722 not create a compatibility issue for precompiled modules, etc.

9728 *) Extend the output of the -V switch to include the paths of all
9729 compiled-in configuration files, if they were overridden at
9730 compile time, for least astonishment of the user.
9733 *) When READing a request in ExtendedStatus mode, the "old"
9734 vhost, request and client information is not displayed.
9737 *) STATUS is no longer available. Full status information now
9738 run-time configurable using the ExtendedStatus directive.
9741 *) SECURITY: CVE-1999-1199 (cve.mitre.org)
9742 Eliminate O(n^2) space DoS attacks (and other O(n^2)
9743 cpu time attacks) in header parsing. Add ap_overlap_tables(),
9744 a function which can be used to perform bulk update operations
9745 on tables in a more efficient manner. [Dean Gaudet]
9747 *) SECURITY: Added compile-time and configurable limits for
9748 various aspects of reading a client request to avoid some simple
9749 denial of service attacks, including limits on maximum request-line
9750 size (LimitRequestLine), number of header fields (LimitRequestFields),
9751 and size of any one header field (LimitRequestFieldsize). Also added
9752 a configurable directive LimitRequestBody for limiting the size of the
9753 request message body. [Roy Fielding]

9756 STATUS not defined. [Jim Jagielski]
9758 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]

9769 ap_scan_script_header_err_core() [Doug MacEachern]
9771 *) The 'status' module will now show the process pid's and their
9772 state even without full STATUS accounting. [Jim Jagielski]
9774 *) Restore the client IP address to the error log messages, this
9775 was lost during the transition from 1.2 to 1.3. Add a new
9776 function ap_log_rerror() which takes a request_rec * and
9777 formats it appropriately. [Dean Gaudet] PR#2661
9779 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
9780 whitespace in input lines -- including within quoted strings.
9782 but leading and trailing whitespace should continue to be
9783 stripped [Martin Kraemer]
9785 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
9786 the ugly use of an env. variable and use command-line args for
9787 alternate $PATH. Make more like advanced 'type's as well.
9790 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
9791 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis

9794 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
9796 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
9797 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
9798 directory was renamed to src/os/os2/ for consistency.
9799 [Brian Havard, Ralf S. Engelschall]
9801 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
9802 files (here modules) against other DSO files (here shared libraries).
9803 This is done by determining a subset of LIBS which can be safely used for
9804 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
9805 disabled for all platforms to avoid problems with this (experimental)
9806 rule. But we provide it now for those people how ran into problems and
9807 want to came out by forcing linking against DSOs.

9826 *) One more portability fix for APACI shadow tree support: Swap order of awk
9827 and sed in top-level configure script to avoid sed fails on some

9958 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
9959 TestCompile) instead of defining them manually in conf.h based on less
9960 accurate platform definitions. This way we no longer have to fiddle with
9961 OS-type and/or OS-version identifiers to discover whether a system header
9962 file exists or not. Instead we now directly check for the existence of
9963 those esoteric ones.

9967 *) mod_setenvif (BrowserMatch* and friends) will now match a missing
9968 field with "^$". [Ken Coar]
9970 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
9971 modules to load their own modules dynamically. This improves mod_perl
9972 and mod_php3 when these modules are loaded dynamically into Apache.

10003 *) The APACI libexecdir was not extended with an "apache/" subdir
10004 if the installation prefix didn't already contain "apache", but
10005 it should be because the DSO files are Apache-specific. Now
10006 libexecdir is treated the same way sysconfdir, datadir, localstatedir

10060 directory, bail out of the request with an error message. [W G Stoddard]
10062 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
10063 these are treated by Win32 as if they are ".." but are not detected by
10064 other machinery within Apache. This is something of a kludge but
10065 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
10067 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
10068 pools and thus pollutes libap (until the pool stuff is moved there).
10071 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
10072 but case-insensitive platforms). New #define for this added to conf.h

10082 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
10083 remove some of the classical hurdles for new users when setting up
10084 Apache. This is done per default because it is useful for the average
10085 user. Package authors can use the --without-confadjust option to disable
10086 these configuration adjustments.
10087 [Ralf S. Engelschall]
10089 *) Added an EXTRA_DEPS configuration parameter which can be used
10090 to add an extra Makefile dependency for the httpd target, for instance
10091 to external third-party libraries, etc.
10092 [Ralf S. Engelschall]
10094 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
10095 as <IfModule>..</IfModule> sections) which can be used to skip or process
10096 contained commands dependend of ``-D PARAMETER'' options on the command
10097 line. This can be used to achieve logical conditions like <IfDefine
10098 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
10099 and thus especially can be used for conditionally loading DSO-based
10100 modules via LoadModule, etc. [Ralf S. Engelschall]

10111 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
10112 in top-level configure script to avoid sed fails on some platforms (for
10113 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
10114 output of Awk. [Bill Houle <bhoule sandiegoca.ncr.com>] PR#2435
10116 *) Improve performance of directory listings (mod_autoindex) by comparing
10117 integer keys (last-modified and size) as integers rather than converting
10118 them to strings first. Also use a set of explicit byte tests rather
10119 than strcmp() to check for parent directory-ness of an entry. Oh, and
10120 make sure the parent directory (if displayed) is *always* listed first
10121 regardless of the sort key. Overall performance winnage should be good
10122 in CPU time, instruction cache, and memory usage, particularly for large
10123 directories. [Ken Coar]
10125 *) Add a tiny but useful goody to APACI's configure script: The generation
10126 of a config.status script (as GNU Autoconf does) which remembers the used
10127 configure command and hence can be used to restore the configuration by
10128 just re-running this script or for remembering the configuration between
10130 [Ralf S. Engelschall]
10132 *) Add httpd -t (test) option for running configuration syntax tests only.
10133 If something is broken it complains and exits with a return code
10134 non-equal to 0. This can be used manually by the user to check the Apache
10135 configuration after editing and is also automatically used by apachectl
10136 on (graceful) restart command to make sure Apache doesn't die on restarts
10137 because of a configuration which is now broken since the last (re)start.
10138 This way `apachectl restart' can be used inside cronjobs without having
10139 to expect Apache to be falling down. Additionally the httpd -t can be run
10140 via `apachectl configtest'.

10280 spawn_child was obsoleted and moved to compat.h
10283 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
10284 programs: ap_spawn_child_err() is used and the Win32 case now uses
10285 CreateProcess() instead of a low-level execl() (which caused problems in
10286 the past under Win32).

10289 *) A few cosmetics and trivial enhancements to APXS to make the
10290 generated Makefile more user friendly. [Ralf S. Engelschall]
10292 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
10293 was updated to use the normal apache error processing, thereby allowing
10294 proxy errors to be treated by ErrorDocument's as well. For this
10295 purpose, a new module-to-core communication variable "error-notes"
10296 was introduced; the proxy (and possibly other modules) communicates
10297 its error text using this variable. Its content is copied to a new
10298 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
10299 The old proxy special error routine ap_proxy_log_uerror()
10300 was replaced by regular ap_log_error() calls, many messages were made
10302 [Martin Kraemer] PR#494, 1259
10304 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
10307 *) Transform the configure message "You need root privileges for suEXEC"
10308 from a fatal error into a (more friendly) warning because the building
10309 ("make") of Apache we can allow, of course. Root privileges are needed
10310 only for the installation step ("make install"). So make sure the
10311 user is aware of this fact but let him proceed as long as he can.

10378 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
10380 *) The Makefiles assumed that DSO files are build via $(LD). This
10381 is broken for two reasons: First we never defined at least LD=ld
10382 somewhere to make sure this works (it was silently assumed that most Make
10383 provide a built-in LD definition - ARGL!) and second using the generic LD
10384 variable is not the truth. Instead a special variable named LD_SHLIB is
10385 reasonable because although "ld" is usually the default, the command for
10386 building DSO files can be "libtool" or even "cc" on some systems.

10399 not retrieved in src/Configure and thus was not useable.
10400 [Ralf S. Engelschall]
10402 *) Various Makefile consistency cleanups:
10403 - make OSDIR also automatically be relative to src/ like INCDIR
10404 - SUBDIRS is now generated in src/Makefile only and not in
10405 Makefile.config because it is a local define for this location.
10406 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
10407 any Makefile but make sure that at least the "-K inline" is kept in
10409 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
10410 - updated the dependencies theirself
10411 - removed not existing SHLIB variable from "clean" targets
10412 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
10413 already exists and OBJS_PIC are also just plain objects and have not
10414 directly to do with "shared" things. The only difference is that they
10415 contain PIC. So OBJS_PIC is the more canonical name.
10416 - Updated the Makefile-dependency lines for OBJS_PIC
10417 - Removed the Makefile-dependency line in Configure to avoid double
10419 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
10420 of xxx.lo as GNU libtool does with its PIC objects
10421 - reduce local complexity in modules Makefile.tmpl by moving the last
10422 existing target "depend" to the generation section in Configure, too.
10423 - removed the historical $(SPACER) which was used in the past together
10424 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
10425 is no longer needed.
10426 - force the build and run of the gen_xxx programs under main/ as the
10427 first step before building the objects because it looks cleaner
10428 [Ralf S. Engelschall]
10430 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
10433 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
10436 *) WIN32: Don't force ISAPI headers to finish with \n.
10437 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
10439 *) When opening "configuration" files (like httpd.conf, htaccess
10440 and htpasswd), Apache will not allow them to be non-/dev/null
10441 device files. This closes a DoS hole. At the same time,
10442 we use ap_pfopen to open these files to handle timeouts.
10443 [Jim Jagielski, Martin Kraemer]
10445 *) Apache will now log the reason its httpd children exit if they exit
10446 due to an unexpected signal. (It requires a new porting define,
10447 SYS_SIGLIST, which if defined should point to a list of text
10448 descriptions of the signals available. See PORTING.) [Dean Gaudet]
10450 *) WIN32: chdir() doesn't make sense in a multithreaded environment
10451 like WIN32. Before, Win32 CGI's could have had sporadic failures
10452 if a chdir call from one thread was made between another chdir call
10453 and a spawn in another thread. So, for now don't chdir for CGI scripts
10454 in WIN32. The current CGI "spec" is unclear as to whether it's
10455 necessary. Long-term fix is to either serialize the chdir/spawn combo
10456 or use WIN32 native calls to spawn a process. This temp fix was
10457 necessary to remove this as a showstopper for 1.3's release.
10460 *) Cleanup the suEXEC support in APACI and make it more safe:
10461 1. Add big fat hint in INSTALL about risks and to read the
10462 htdocs/manual/suexec.html document before using the suexec-related
10464 2. Make sure the user has at least provided one --suexec-xxxx option
10465 (specifies suEXEC parameters) in addition to --enable-suexec option.
10466 If only --enable-suexec is given APACI stops with a hint to INSTALL
10467 and htdocs/manual/suexec.html documents.
10468 3. Provide two additional --suexec-xxxx options to make the suEXEC
10469 configuration complete (especially for package maintainers who else
10470 had to patch the source tree) by providing ways to configure minimal
10471 UID/GID and safe PATH, too.
10472 [Ralf S. Engelschall]
10474 *) Cleanup of the `configure --shadow' process:
10475 - make sure the configure script creates its temporary files in the
10476 shadow tree to avoid conflicts with parallel configure runs
10477 - removed unnecessary option "-r" from "rm" call for Makefiles
10478 - make sure the configure scripts creates the shadow-wrapper Makefile
10479 only when no shadow trees already exists
10480 - make sure "make distclean" removes the shadow-wrapper Makefile but only
10481 when no more shadow trees exists
10482 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
10483 as fast (in the past it needed 70sec, now it runs just 38sec)
10484 - make sure CVS does not complain about the created files
10485 Makefille.<gnutriple> and directories src.<gnutriple>
10486 [Ralf S. Engelschall]
10488 *) Added the ap_add_version_component() API routine and the
10489 AddVersionPlatform core directive. The first allows modules to
10490 declare themselves in the Server response header field value,
10491 augmenting the SERVER_SUBVERSION define in the Configuration file
10492 with run-time settings (more useful in a loadable-module environment).
10493 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
10494 into the server version string. [Ken Coar] PR#2056
10496 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
10499 *) Emit the "Accept-Range" header for the default handler.
10500 [Brian Behlendorf] PR#1464
10502 *) Add a note to httpd.conf-dist that apache will on some systems fail
10503 to start when the Group # is set to a negative or large positive value.
10506 *) Make sure the module execution order is correct even when some modules
10507 are loaded under runtime (`LoadModule') via the DSO mechanism:
10508 1. The list of loaded modules is now a dynamically allocated one
10509 and not the original statically list from modules.c
10510 2. The loaded modules are now correctly setup by LoadModule for
10511 later use by the AddModule command.
10512 3. When the DSO mechanism for modules is used APACI's `install'
10513 target now enables all created `LoadModule' lines per default because
10514 this is both already expected by the user _and_ needed to avoid
10515 confusion with the next point and reduces the Makefile.tmpl complexity
10516 4. When the DSO mechanism for modules is used, APACI's `install'
10517 target now additionally makes sure the module list is reconstructed
10518 via a complete `ClearModuleList+AddModule...' entry.
10519 5. The support tool `apxs' now also makes sure an AddModule command
10520 is added in addition to the LoadModule command.
10521 6. The modules.c generation was extended to now contain two
10522 comments to make sure no one is confused by the confusing terminology
10523 of loading/linking (we use load=link+load & link=activate instead of
10524 the obvious load=activate & link=link :-( )
10525 This way now there is no longer a difference under execution time between
10526 statically and dynamically linked modules.
10527 [Ralf S. Engelschall]
10529 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
10530 Big Symbol Renaming. [Ralf S. Engelschall]
10532 *) Add a comment to mod_example.c showing the format of a FLAG command
10533 handler. [Ken Coar]
10535 *) Standardized the time format in mod_status to match that of other
10536 places in the code (e.g. DATE_GMT). PR#1551
10538 *) Fix handling of %Z in timefmt strings for those platforms with no time
10539 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
10542 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
10543 feature compatible with 'UseCanonicalName off' by changing
10544 r->server->server_hostname to ap_get_server_name(). And I changed some
10545 functions which use r->server->port to use ap_get_server_port() instead,
10546 because if there's no Port directive in the config r->server->port is 0.
10549 *) get/set_module_config are trivial enough to be better off inline. Worth
10550 1.5% performance boost. [Dean Gaudet]
10552 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
10553 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
10556 *) [BS2000 security] BS2000 needs an extra authentication to initialize
10557 the task environment to the unprivileged User id. Otherwise CGI scripts
10558 would have a way to gain super user access. [Martin Kraemer]
10560 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
10561 absolute path, only log base name of logging source as is done
10562 in unix. [Martin Kraemer]
10564 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
10565 the encoding type from the Accept-Encoding header (if it's there)
10566 and use it in the response, as that's probably what it'll be expecting.
10567 [<Ronald.Tschalaer psi.ch>]
10569 *) Fix to mod_alias: translate_alias_redir is dealing with
10570 a URI, not a filename, so the check for drive letters for win32
10571 and emx is not necessary. [Dean Gaudet]
10573 *) WIN32: Allow .cmd as an executable extension.
10574 [Kari Likovuori <Kari.Likovuori mol.fi>] PR#2146
10576 *) Make Apache header files, and some variables, C++ friendly.
10577 [Michael Anderson's <mka redes.int.com.mx>]
10579 *) Child processes can now "signal" (by exiting with a status
10580 of APEXIT_CHILDFATAL) the parent process to abort and
10581 shutdown the server if the error in the child process was
10582 fatal enough. [Jim Jagielski]
10584 *) mod_autoindex's find_itme() was sensitive to MIME type case.
10585 [Jim Jagielski] PR#2112
10587 *) Make sure the referer_log and agent_log entries in the default httpd.conf
10588 file are also adjusted for the actual relative installation paths.
10589 [Ralf S. Engelschall] PR#2175
10591 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
10593 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
10596 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
10597 Additionally the checks for finding the vendor DSO library were moved
10598 from mod_so.c to Configure because first it needs $PLAT etc. and second
10599 mod_so already uses an abstraction layer and does not fiddle with the
10600 vendor functions itself.
10601 [Jens-Uwe Mager, Ralf S. Engelschall]
10603 *) PORT: Some optimization defines for NetBSD
10604 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
10606 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
10607 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
10609 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
10610 AIX variants should work fine, too. Even AIX 3.x should work). This is
10611 accomplished by using the free DSO emulation code from Jens-Uwe Mager
10612 which we put into a os/unix/os-dso-aix.c file.
10613 [Ralf S. Engelschall]
10615 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
10616 that we should use NET_SIZE_T == int but the include files force size_t.
10617 [Ralf S. Engelschall]
10619 *) Fix two bugs in select() handling in http_main.c.
10622 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
10623 is unset (as it is in situations like timeouts) where it is unclear
10624 whether errno is set or not. [Martin Kraemer]
10626 *) Just having APACI's localstatedir is too general and not enough for most
10627 of the systems. 1.3b6 again required manual APACI patches by package
10628 maintainers from Red Hat and FreeBSD because for their filesystem layout a
10629 little bit more flexibility in configuring the paths is needed. Hence we
10630 provide three additional configure options (--runtimedir, --logfiledir,
10631 --proxycachedir) which now can be used for more granular adjustments if
10632 --localstatedir is not enough to fit the particular needs. As a nice
10633 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
10634 [Ralf S. Engelschall]
10636 *) Make the install root for "make install" in APACI's Makefile overrideable
10637 by package authors. This way we are even more friendly to package
10638 maintainers (especially Debian and Red Hat) who build for the real prefix
10639 via "configure --prefix=/<real>" but use a different local prefix via
10640 "make root=/tmp/apache install" for rolling the package without bristling
10641 the target location on their system.
10642 [Ralf S. Engelschall]
10644 *) Workaround sed limitations in APACI's configure script by now
10645 substituting in chunks of 50 commands (because for instance HPUX's vendor
10646 sed has a limit of max. 98 commands)
10647 [Ralf S. Engelschall] PR#2136
10649 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
10650 [Ralf S. Engelschall] PR#2140
10652 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
10653 RENAMING process because they are defined as pre-processor macros instead
10654 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
10655 [Ralf S. Engelschall]
10657 *) Workaround braindead AWK's when generating ap_config.h: The split() and
10658 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
10659 [Ralf S. Engelschall] PR#2139
10661 *) Various bugfixes and cleanups for the APACI configure script:
10662 o fix IFS handling for _nested_ situation
10663 o fix Perl interpreter search: take first one found instead of last one
10664 o fix DSO consistency check
10665 o print error messages to stderr instead of stdout
10666 o add install-quiet for --shadow situation to Makefile stub
10667 o reduce complexity by avoiding sed-hacks for rule and module list loops
10668 [Ralf S. Engelschall]
10670 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
10672 *) Make sure the input field separator (IFS) shell variable is explicitly
10673 initialized correctly before _every_ `for' loop and also restored after
10674 the loops. [Ralf S. Engelschall]
10676 *) Make sure that "make install" doesn't overwrite the `mime.types' and
10677 `magic' files from an existing Apache installation. Because people often
10678 customize these for own MIME and content types.
10679 [Ralf S. Engelschall]
10681 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
10682 [Peter Galbavy, Ralf S. Engelschall] PR#2109
10684 *) Fix the path to the ScoreBoardFile in the install-config target, too.
10685 [Ralf S. Engelschall] PR#2105
10687 *) Let "configure" clear out the users parameters (provided as shell
10688 variables) to avoid side-effects in "src/Configure" when the user
10689 exported them (which is not needed, but some users do it).
10690 [Ralf S. Engelschall] PR#2101
10692 *) Provide backward compatibility from some old src/Configuration.tmpl
10693 parameter names to the canonical Autoconf-style shell variable names. For
10694 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
10695 but a hint message is displayed. [Ralf S. Engelschall]
10697 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
10698 CGI scripts from an existing Apache installation.
10699 [Ralf S. Engelschall, Jim Jagielski] PR#2084
10701 *) Make `configure --compat' more "compatible" by first
10702 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
10703 second by making sure the "avoid-bristling-suffix" /apache is not
10704 appended to sysconfdir, datadir, localstatedir and includedir when
10705 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
10707 *) NeXT required strdup() in support/logresolve.c
10708 [Francisco Tomei <fatomei sandburg.unm.edu>] PR#2082
10710 *) AIX required sys/select.h in support/ab.c
10711 [Jens Schleusener <Jens.Schleusener dlr.de>] PR#2081
10713 *) Fix the path to the MimeMagicFile in the install-config target, too.
10714 [Ralf S. Engelschall] PR#2089
10716 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
10718 *) If you start apache with the -S command line option it will dump
10719 out the parsed vhost settings. This is useful for folks trying
10720 to figure out what is wrong with their vhost configuration.
10721 (Other dumps may be added in the future.) [Dean Gaudet]
10723 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
10724 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
10727 *) Because /usr/local/apache is the default prefix the ``configure
10728 --compat'' option no longer has to set prefix, again. This way the
10729 --compat option honors a leading --prefix option. [Lars Eilebrecht]
10731 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
10732 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
10733 to avoid "discard const" warnings. [Ralf S. Engelschall]
10735 *) If a specific handler is set for a file yet the request still
10736 ends up being handled by the default handler, log an error
10737 message before handling it. This catches things such as trying
10738 to use SSIs without mod_include enabled. [Marc Slemko]
10740 *) Fix error logging for the startup case where ap_log_error() still uses
10741 stderr as the target. Now the default log level is honored here, too.
10742 [Ralf S. Engelschall]
10744 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
10745 long" errors when generating the MODULES entry for src/Makefile
10746 [Ben Hyde, Ralf S. Engelschall]
10748 *) Make sure src/Configure doesn't complain about the old directory
10749 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
10751 Changes with Apache 1.3b6
10753 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
10755 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
10756 interface via the similar but proprietary HP/UX shl_xxx-style system
10757 calls. [Ralf S. Engelschall]
10759 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
10760 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
10761 Make. [Ralf S. Engelschall]
10763 *) ++++ THE BIG SYMBOL RENAMING ++++
10764 To avoid symbol clashes with third-party code compiled into the server,
10765 we globally applied the prefix "ap_" to the following classes of
10767 - Apache provided general functions (e.g., ap_cpystrn)
10768 - Public API functions (e.g., palloc, bgets)
10769 - Private functions which we can't make static (because of
10770 cross-object usage) but should be (e.g., new_connection)
10771 For backward source compatibility a new header file named compat.h was
10772 created which provides defines for the old symbol names and can be used
10773 by third-party module authors.
10776 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
10777 problem under SVR4 is that there is no command flag to force the linker
10778 to export the global symbols of the httpd executable therewith they are
10779 available to the DSO's. Instead of problematic hacks like creating a
10780 dummy.so file (containing dummy references to all global symbols) the
10781 httpd binary is linked against, we use a clean trick stolen from Perl 5:
10782 Placing the Apache core code itself into a DSO library named libhttpd.so.
10783 This way the global symbols _HAVE_ to be exported and thus are available
10784 to any manually loaded DSO's under runtime. To reduce the impact to the
10785 user to null we go even further and create a stub httpd executable which
10786 automatically keeps track of the DSO library loading itself and thus
10787 hides the complete mechanism from the user. Although the generation of
10788 this DSO library is automatically triggered for platforms which
10789 essentially need it (mostly all SVR4-derivates) it can be also enabled
10790 manually via the Rule SHARED_CORE. This can be interesting in the future
10791 where we perhaps exploit this libhttpd.so mechanism for providing nifty
10792 features like graceful upgrades, or whatever.
10793 [Ralf S. Engelschall, Martin Kraemer]
10795 *) Build the libraries before building the rest of the tools. [Ben Hyde]
10797 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
10798 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
10799 conventions while "clean" removes only stuff created by "all" targets,
10800 "distclean" additionally removes the stuff from the configuration
10801 process. This way "make distclean" (hence the name) provides a fresh
10802 source tree as it was for distribution.
10803 [Ralf S. Engelschall]
10805 *) Allow top-level (APACI) Makefile to break on build errors
10806 the same way the src/ subtree Makefiles breaks on them by replacing the
10807 initial APACI sed-subdir-display-kludge with a more clean
10808 variable-passing-solution: variable SDP can optionally hold the subdir
10809 prefix which is consistently used for displaying the subdir movement.
10810 This way even the top-level Makefile can stop correctly on errors as the
10811 user expects. [Ralf S. Engelschall]
10813 *) Fixed ordering of argument checks for RewriteBase directive.
10814 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
10816 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
10817 indicating that a module is being compiled for dynamic loading. Also
10818 remove #define IS_MODULE from modules and add SHARED_MODULE define
10819 to the mak/dsp files. [Alexei Kosut]
10821 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
10822 since we are now logging APLOG_WARNING by default. [Roy Fielding]
10824 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
10826 *) Add documentation file and src/Configuration.tmpl entry for the
10827 experimental mod_mmap_static module. Because although it is and marked as
10828 an experimental one it is distributed and thus should be documented and
10829 prepared for configuration the same way as all others modules.
10830 [Ralf S. Engelschall]
10832 *) Add query (-q) option to apxs support tool to be able to manually query
10833 specific settings from apxs. This is needed for instance when you
10834 manually want to access Apache's header files and you need to assemble
10835 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
10836 [Ralf S. Engelschall]
10838 *) Now src/Configure uses a fallback strategy for the shared object support
10839 on platforms where no explicit information is available: If a Perl
10840 installation exists we ask it about its shared object support and if it's
10841 the dlopen-style one we shamelessly guess the compiler and linker flags
10842 for creating shared objects from Perls knowledge. Of course, the user is
10843 warning about what we are doing and informed that he should send us
10844 the guessed flags when they work. [Ralf S. Engelschall]
10846 *) Provide APACI --without-support option to be able to disable the build
10847 and installation of the support tools from the src/support/ area.
10848 Although its useful to have these installed per default we should provide
10849 a way to compile and install without them for backward-compatibility.
10850 [Ralf S. Engelschall]
10852 *) Add of the new APache eXtenSion (apxs) support tool for building and
10853 installing modules into an _already installed_ Apache package through the
10854 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
10855 this approach actually doesn't need the Apache source tree. The
10856 (APACI-installed) server package is enough, because this now includes the
10857 Apache C header files (PREFIX/include) and the new APXS tool
10858 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
10859 module authors to build their Apache modules _OUTSIDE_ the Apache source
10860 tree while avoiding them to fiddle around with the totally platform
10861 dependend way of compiling DSO files. The tool supports all ranges of
10862 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
10863 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
10864 on-the-fly generate a minimalistic Makefile and sample module for the
10865 first step to provide both a quick success event and to demonstrate the
10866 APXS mechanism to module authors. [Ralf S. Engelschall]
10868 *) Fix core dumps in use of CONNECT in proxy.
10869 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
10871 *) Modify the log directives in httpd.conf-dist files to use CustomLog
10872 so that users have examples of how CustomLog can be used.
10875 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
10876 the Apache distribution tree. Until Apache 1.3 there was no real
10877 out-of-the-box batch-capable build and installation procedure for the
10878 complete Apache package. This is now provided by a top-level "configure"
10879 script and a corresponding top-level "Makefile.tmpl" file. The goal is
10880 to provide a GNU Autoconf-style frontend which is capable to both drive
10881 the old src/Configure stuff in batch and additionally installs the
10882 package with a GNU-conforming directory layout. Any options from the old
10883 configuration scheme are available plus a lot of new options for flexibly
10884 customizing Apache. [Ralf S. Engelschall]
10886 *) The floating point ap_snprintf code wasn't threadsafe.

10901 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
10902 a generic printf-style routine that can call arbitrary output
10903 routines. Use this to replace http_bprintf.c. Add new routines
10904 psprintf(), pvsprintf() which allocate the exact amount of memory
10905 required for a string from a pool. Use psprintf() to clean up
10906 various bits of code which used ap_snprintf()/pstrdup().
10909 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
10910 ap_snprintf() has different semantics and formatting codes than

10944 *) Allow %2F in two situations: 1) it is in the query part of the URI,
10945 therefore not exposed to %2F -> '/' translations and 2) the request
10946 is a proxy request, so we're not dealing with a local resource anyway.
10947 Without this, the proxy would fail to work for any URL's with

10981 document our stuff a little bit more and to be able to do really
10982 Unix-like installations ;-) [Ralf S. Engelschall]
10984 *) Major cleanups to the Configure script to make it and its generated
10985 Makefiles again readable and maintainable: add SRCDIR option, removed
10986 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
10987 generated sections, consequently added Makefile headers with inheritance
10988 information, added subdir movement messages for easier following where
10989 the build process currently stays (more verbose then standard Make, less
10990 verbose than GNU make), same style to comments in the Configure script,
10991 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
10993 *) Add the new ApacheBench program "ab" to src/support/: This is derived

11018 *) Clean up some undocumented behavior of mod_setenvif related to
11019 "merging" two SetEnvIf directives when they match the same header
11020 and regex. Document that mod_setenvif will perform comparisons in
11021 the order they appear in the config file. Optimize mod_setenvif by
11022 doing more work at config time rather than at runtime.
11025 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
11026 to allow for modules to overrule them and to reduce redefinition
11027 warnings [Jim Jagielski]
11029 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
11032 *) Making the hard-coded cross-module function call mime_find_ct() (from
11033 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
11034 checking is really called even for proxy requests except for URLs with
11035 HTTP schemes (because there we can optimize by not running the type
11036 checking hooks due to the fact that the proxy gets the MIME Content-type
11037 from the remote host later). This change cleans up mod_mime by removing
11038 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
11039 especially unbundles mod_proxy and mod_mime. This way they both now can
11040 be compiled as shared objects and are no longer tied together.

11043 *) util.c cleanup and speedup. [Dean Gaudet]

11055 *) Performance improvements to invoke_handler().
11056 [Dmitry Khrustalev <dima bog.msu.su>]
11058 *) Added support for building shared objects even for library-style modules
11059 (which are built from more than one object file). This now provides the
11060 ability to build mod_proxy as a shared object module. Additionally
11061 modules like mod_example are now also supported for shared object
11062 building because the generated Makefiles now no longer assume there is at
11063 least one statically linked module. [Ralf S. Engelschall]
11065 *) API: Clarify usage of content_type, handler, content_encoding,
11066 content_language and content_languages fields in request_rec. They
11067 must always be lowercased; and the strings pointed to shouldn't
11068 be modified (you must copy them to modify them). Fix a few bugs
11069 related to this. [Dean Gaudet]
11071 *) API: Clarification: except for RAW_ARGS, all command handlers can
11072 treat the char * parameters as permanent, and modifiable. There
11073 is no need to pstrdup() them. Clean up some needless pstrdup().
11076 *) Now mod_so keeps track of which module shared objects with which names
11077 are loaded and thus avoids multiple loading and unloading and irritating
11078 error_log messages. [Ralf S. Engelschall]
11080 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
11081 environment variable in the apache core. But that tweaking interferes

11102 and USE_OS2_SCOREBOARD. [Dean Gaudet]
11104 *) Fix one more special locking problem for RewriteMap programs in
11105 mod_rewrite: According to the documentation of flock(), "Locks are on
11106 files, not file descriptors. That is, file descriptors duplicated
11107 through dup(2) or fork(2) do not result in multiple instances of a lock,
11108 but rather multiple references to a single lock. If a process holding a
11109 lock on a file forks and the child explicitly unlocks the file, the
11110 parent will lose its lock.". To overcome this we have to make sure the
11111 RewriteLock file is opened _AFTER_ the childs were spawned which is now
11112 the case by opening it in the child_init instead of the module_init API
11113 hook. [Ralf S. Engelschall] PR#1029
11115 *) Change to Location and LocationMatch semantics. LocationMatch no
11116 longer lets a single slash match multiple adjacent slashes in the
11117 URL. This change is for consistency with RewriteRule and
11118 AliasMatch. Multiple slashes have meaning in URLs that they do
11119 not have in (some) filesystems. Location on the other hand can
11120 be considered a shorthand for a more complicated regex, and it
11121 does match multiple slashes with a single slash -- which is
11122 also consistent with the Alias directive.

11125 *) Fix bug with mod_mime_magic causing certain files, including files
11126 of length 0, to result in no response from the server.
11129 *) The Configure script now generates src/include/ap_config.h which
11130 contains the set of defines used when Apache is compiled on a platform.
11131 This file can then be included by external modules before including
11132 any Apache header files in case they are being built separately from
11133 Apache. Along with this change, a couple of minor changes were
11134 made to make Apache's #defines coexist peacefully with any autoconf
11135 defines an external module might have. [Rasmus Lerdorf]
11137 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
11138 but without any RewriteXXXXX directives. Here mod_rewrite is given no
11139 chance by the API to initialize its per-server configuration and thus
11140 receives the wrong one from the main server. This is now avoided by
11141 remembering the server together with the config structure while
11142 configuring and later assuming there is no config when we see a
11143 difference between the remembered server and the one calling us.
11144 [Ralf S. Engelschall] PR#1790
11146 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
11147 is automatically disabled under configure time when the dbm_xxx functions
11148 are not available. Second, two heavy source code errors in the DBM
11149 support code were fixed. This makes DBM RewriteMap's usable again after
11150 a long time of brokenness. [Ralf S. Engelschall] PR#1696
11152 *) Now all configuration files support Unix-style line-continuation via
11153 the trailing backslash ("\") character. This enables us to write down
11154 complex or just very long directives in a more readable way. The
11155 backslash character has to be really the last character before the

11172 depending on the rev of Solaris and what mixture of modules
11173 are in use. So it has been disabled, and Solaris is back to
11174 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
11175 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
11176 up static content only servers. Or it may fail unpredictably.

11179 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
11182 *) API: Rewrite of absoluteURI handling, and in particular how
11183 absoluteURIs match vhosts. Unless a request is a proxy request, a
11184 "http://host" url is treated as if a similar "Host:" header had been
11185 supplied. This change was made to support future HTTP/1.x protocols
11186 which may require clients to send absoluteURIs for all requests.
11188 In order to achieve this change subtle changes were made to the API. In a
11189 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
11190 that the unmodified uri can be retrieved easily. r->proxyreq is not set
11191 by the core, modules must set it during the post_read_request or
11192 translate_names phase.
11194 Plus changes to the virtualhost test suite for absoluteURI testing.
11196 This fixes several bugs with the proxy proxying requests to vhosts
11197 managed by the same httpd.
11200 *) API: Cleanup of code in http_vhost.c, and remove vhost matching

11218 *) API: A new source module main/util_uri.c; It contains a routine
11219 parse_uri_components() and friends which breaks a URI into its component
11220 parts. These parts are stored in a uri_components structure called
11221 parsed_uri within each request_rec, and are available to all modules.
11222 Additionally, an unparse routine is supplied which re-assembles the URI
11223 components back to an URI, optionally hiding the username:password@ part
11224 from ftp proxy requests, and other useful routines. Within the structure,
11225 you find on a ready-for-use basis:
11226 scheme; /* scheme ("http"/"ftp"/...) */
11227 hostinfo; /* combined [user[:password]@]host[:port] */
11228 user; /* user name, as in http://user:passwd@host:port/ */
11229 password; /* password, as in http://user:passwd@host:port/ */
11230 hostname; /* hostname from URI (or from Host: header) */
11231 port_str; /* port string (integer representation is in "port") */
11232 path; /* the request path (or "/" if only scheme://host was given) */
11233 query; /* Everything after a '?' in the path, if present */
11234 fragment; /* Trailing "#fragment" string, if present */
11235 This is meant to serve as the platform for *BIG* savings in
11236 code complexity for the proxy module (and maybe the vhost logic).
11239 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and

11354 semantic ordering). [Dean Gaudet] PR#379
11356 *) <Files> with wildcards was broken by the change in wildcard
11357 semantics (* does not match /). To fix this, <Files> now
11358 apply only to the basename of the request filename. This
11359 fixes some other inconsistencies in <Files> semantics
11360 (such as <Files a*b> not working). [Dean Gaudet] PR#1817
11362 *) Removed bogus "dist.tar" target from Makefile.tmpl and make sure
11363 backup files are removed on "clean" target [Ralf S. Engelschall]
11365 *) PORT: Add -lm to LIBS for HPUX. [Dean Gaudet] PR#1639
11367 *) Various errors from select() and accept() in child_main() would
11368 result in an infinite loop. It seems these two tickle kernel
11369 or library bugs occasionally, and result in log spammage and
11370 a generally bad scene. Now the child exits immediately,
11371 which seems to be a good workaround.

11374 *) Cleaned up some race conditions in unix child_main during
11375 initialization. [Dean Gaudet]
11377 *) SECURITY: "UserDir /abspath" without a * in the path would allow
11378 remote users to access "/~.." and bypass access restrictions
11379 (but note /~../.. was handled properly).
11380 [Lauri Jesmin <jesmin ut.ee>] PR#1701
11382 *) API: os_is_path_absolute() now takes a const char * instead of a char *.
11385 Changes with Apache 1.3b5
11387 *) Source file dependencies in Makefile.tmpl files throughout the
11388 source tree were updated to accurately reflect reality.
11391 *) Preserve the content encoding given by the AddEncoding directive
11392 when the client doesn't otherwise specify an encoding.
11393 [Ronald Tschalaer <Ronald.Tschalaer psi.ch>]
11395 *) Sort out problems with canonical filename handling happening too late.
11396 [Dean Gaudet, Ben Laurie]
11398 Changes with Apache 1.3b4
11400 *) The module structure was modified to include a *dynamic_load_handle
11401 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
11402 has been bumped accordingly. [Paul Sutton]
11404 *) All BrowserMatch directives mentioned in
11405 htdocs/manual/known_client_problems.html are in the default
11406 configuration files. [Lars Eilebrecht]
11408 *) MiNT port update. [Jan Paul Schmidt]
11410 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
11411 equivalent, similarly for x-compress and compress. Apache
11412 now ignores a leading x- when comparing encodings. It also
11413 preserves the encoding the client requests (for example if
11414 it requests x-gzip, then Apache will respond with x-gzip
11415 in the Content-Encoding header).
11416 [Ronald Tschalaer <Ronald.Tschalaer psi.ch>] PR#1772
11418 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
11420 *) Added mod_so module to support dynamic loading of modules on Unix
11421 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
11422 instead of AddModule in Configuration to build shared modules
11423 [Sameer Parekh, Paul Sutton]
11425 *) Minor cleanups to r->finfo handling in some modules.
11428 *) Abstract read()/write() to ap_read()/ap_write().
11429 Makes it easier to add other types of IO code such as SFIO.
11432 *) API: Generalize default_port manipulations to make support of
11433 different protocols easier. [Ben Laurie, Randy Terbush]
11435 *) There are many cases where users do not want Apache to form
11436 self-referential urls using the "canonical" ServerName and Port.
11437 The new UseCanonicalName directive (default on), if set to off
11438 will cause Apache to use the client-supplied hostname and port.
11439 API: Part of this change required a change to the construct_url()
11440 prototype; and the addition of get_server_name() and
11442 [Michael Douglass <mikedoug texas.net>, Dean Gaudet]
11443 PR#315, 459, 485, 1433
11445 *) Yet another rearrangement of the source tree.. now all the common
11446 header files are in the src/include directory. The -Imain -Iap
11447 references in Makefiles have been changed to the simpler -Iinclude
11448 instead. In addition to simplifying the build a little bit, this
11449 also makes it clear when a module is referencing something in a
11450 other than kosher manner (e.g., the proxy including mod_mime.h).
11451 Module-private header files (the proxy, mod_mime, the regex library,
11452 and mod_rewrite) have not been moved to src/include; nor have
11453 the OS-abstraction files. [Ken Coar]
11455 *) Fix a bug where r->hostname didn't have the :port stripped
11456 from it. [Dean Gaudet]
11458 *) Tweaked the headers_out table size, and the subprocess_env
11459 table size guess in rename_original_environment(). Added
11460 MAKE_TABLE_PROFILE which can help discover make_table()
11461 calls that use too small an initial guess, see alloc.c.
11464 *) Options and AllowOverride weren't properly merging in the main
11465 server setting inside vhosts (only an issue when you have no
11466 <Directory> or other section containing an Options that affects
11467 a request). Options +foo or -foo in the main_server wouldn't
11468 affect the main_server's lookup defaults. [Dean Gaudet]
11470 *) Variable 'cwd' was being used pointlessly before being set.
11473 *) r->allowed handling cleaned up in the standard modules.
11476 *) Some case-sensitivity issues cleaned up to be consistent with
11477 RFC2068. [Dean Gaudet]
11479 *) SIGURG doesn't exist everywhere.
11480 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
11482 *) mod_unique_id was erroneously generating a second unique id when
11483 an internal redirect occured. Such redirects occur, for example,
11484 when processing a DirectoryIndex match. [Dean Gaudet]
11486 *) API: table_add, table_merge, and table_set include implicit pstrdup()
11487 of the key and value. But in many cases this is not required
11488 because the key/value is a constant, or the value has been built
11489 by pstrcat() or other similar means. New routines table_addn,
11490 table_mergen, and table_setn have been added to the API, these
11491 routines do not pstrdup() their arguments. The core code and
11492 standard modules were changed to take advantage of these routines.
11493 The resulting server is up to 20% faster in some situations.
11495 Note that it is easy to get code subtly wrong if you pass a key/value
11496 which is in a pool other than the pool of the table. The only
11497 safe thing to do is to pass key/values which are in the pool of
11498 the table, or in one of the ancestors of the pool of the table.
11499 i.e. if the table is part of a subrequest, a value from the main
11500 request's pool is OK since the subrequest pool is a sub_pool of the
11501 main request's pool (and therefore has a lifespan at most as long as
11502 the main pool). There is debugging code which can detect improper
11503 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
11504 [Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet]
11506 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
11507 which don't exist on disk more gracefully; handles vhosts properly.
11508 Update documentation to reflect the code -- if there's no
11509 MimeMagicFile directive then the module is not enabled.
11512 *) PORT: Some older *nix dialects cannot automatically start scripts
11513 which begin with a #! interpreter line (the shell starts the scripts
11514 appropriately on these platforms). Apache now supports starting of
11515 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
11516 [Martin Kraemer, with code from Peter Wemm <peter zeus.dialix.oz.au>
11519 *) API: "typedef array_header table" removed from alloc.h, folks should
11520 have been writing to use table as if it were an opaque type, but even
11521 some standard modules got this wrong. By changing the definition
11522 to "typedef struct table table" module authors will receive compile
11523 time warnings that they're doing the wrong thing. This change
11524 facilitates future changes with more sophisticated table
11525 structures. Specifically, module authors should be using table_elts()
11526 to get access to an array_header * for the table. [Dean Gaudet]
11528 *) API: Renamed new_connection() to avoid namespace collision with LDAP
11529 library routines. [Ken Coar, Rasmus Lerdorf]
11531 *) WIN32: mod_speling is now available on the Win32 platform.
11534 *) For clarity the following compile time definition was changed:
11536 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
11538 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
11539 and not be a general notice that the OS has mmap(). Now the
11540 HAVE_MMAP/SHMGET #defines strictly are informational that the
11541 OS has that method of shared memory; the type to use for
11542 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
11543 and USE_SHMGET_SCOREBOARD). This allows outside modules to
11544 determine if shared memory is available and allows Apache
11545 to determine the best method to use for the scoreboard.
11548 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
11549 as do various earlier versions. It should be safe on all versions.
11550 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
11551 the slack code. A few other cleanups for Unixware.

11554 *) PORT: A/UX can handle single-listen accepts without mutex
11555 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
11557 *) When die() happens we need to eat any request body if one exists.
11558 Otherwise we can't continue with a keepalive session. This shows up
11559 as a POST problem with MSIE 4.0, typically against pages which are
11560 authenticated. [Roy Fielding] PR#1399
11562 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
11563 header will be passed to CGIs. This is generally a security hole, so
11564 it's not a default. [Marc Slemko] PR#549
11566 *) Fix Y2K problem with date printing in suexec log.
11567 [Paul Eggert <eggert twinsun.com>] PR#1343
11569 *) WIN32 deserves a pid file. [Ben Hyde]
11571 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
11573 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
11574 The choice of flock vs. fcntl was made based on timings which showed that
11575 even on non-NFS, non-exported filesystems fcntl() was an order of
11576 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
11577 that single socket users will see no difference. [Dean Gaudet] PR#467
11579 *) "File does not exist" error message was erroneously including the
11580 errno. [Marc Slemko]
11582 *) Improve the warning message generated when a client drops the
11583 connection (hits stop button, etc.) during a send. [Roy Fielding]
11585 *) Defining GPROF will disable profiling in the parent and enable it
11586 in the children. If you're profiling under Linux this is pretty much
11587 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
11589 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
11592 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
11593 gcc functionality. Work around it.
11594 [Keith Severson <keith sssd.navy.mil>] PR#1613
11596 *) Some linkers complain when .o files contain no functions.
11597 [Keith Severson <keith sssd.navy.mil>] PR#1614
11599 *) Some const declarations in mod_imap.c that were added for debugging
11600 purposes caused some compilers heartburn without adding any
11601 significant value, so they've been removed. [Ken Coar]
11603 *) The src/main/*.h header files have had #ifndef wrappers added to
11604 insulate them against duplicate calls if they get included through
11605 multiple paths (e.g., in .c files as well as other .h files).
11608 *) The libap routines now have a header file for their prototypes,
11609 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
11611 *) mod_autoindex with a plaintext header file would emit the <PRE>
11612 start-tag before the HTML preamble, rather than after the preamble
11613 but before the header file contents. [John Van Essen <jve gamers.org>]
11616 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
11617 only an issue on systems without a MAXDNAME define or where
11618 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
11620 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
11621 is used to read various types of files such as htaccess and
11622 htpasswd files. [Marc Slemko]
11624 *) SECURITY: Ensure that the buffer returned by ht_time is always
11625 properly null terminated. [Marc Slemko]
11627 *) The "Connection" header could be sent back with multiple "close"
11628 tokens. Not an error, but a waste.
11629 [<Ronald.Tschalaer psi.ch>] PR#1683
11631 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
11632 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
11634 *) "basic" auth needs a case-insensitive comparison.
11635 [<Ronald.Tschalaer psi.ch>] PR#1666
11637 *) For maximum portability, the environment passed to CGIs should
11638 only contain variables whose names match the regex
11639 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
11640 underscores over any character outside the regex. This
11641 affects HTTP_* variables, in a way that should be backward
11642 compatible for all the standard headers; and affects variables
11643 set with SetEnv/BrowserMatch and similar directives.
11646 *) mod_speling returned incorrect HREF's when an ambigous match
11647 was found. Noticed by <robinton amtrash.comlink.de> (Soeren Ziehe)
11648 [Soeren Ziehe <robinton amtrash.comlink.de>, Martin Kraemer]
11650 *) PORT: Apache now compiles & runs on an EBCDIC mainframe
11651 (the Siemens BS2000/OSD family) in the POSIX subsystem
11654 *) PORT: Fix problem killing children when terminating. Allow ^C
11655 to shut down the server. [Brian Havard]
11657 *) pstrdup() is implicit in calls to table_* functions, so there's
11658 no need to do it before calling. Clean up a few cases.
11659 [Marc Slemko, Dean Gaudet]
11661 *) new -C and -c command line arguments
11663 -C "directive" : process directive before reading config files
11664 -c "directive" : process directive after reading config files
11666 httpd -C "PerlModule Apache::httpd_conf"
11667 [Doug MacEachern, Martin Kraemer]
11669 *) WIN32: Fix the execution of CGIs that are scripts and called
11670 with path info that does not have an '=' in.
11671 (eg. http://server/cgi-bin/printenv?foobar)
11672 [Marc Slemko] PR#1591
11674 *) WIN32: Fix a call to os_canonical_filename so it doesn't try to
11675 mess with fake filenames. This fixes proxy caching on
11678 *) SECURITY: General mod_include cleanup, including fixing several
11679 possible buffer overflows and a possible infinite loop.
11680 [Dean Gaudet, Marc Slemko]
11682 *) SECURITY: Numerous changes to mod_imap in a general cleanup
11683 including fixing a possible buffer overflow. [Dean Gaudet]
11685 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
11686 (connections are not dropped). Code can handle graceful restarts
11687 (but there is as yet no way to signal this to Apache). Various
11688 other cleanups. [Paul Sutton]
11690 *) The aplog_error changes specific to 1.3 introduced a buffer
11691 overrun in the (now legacy) log_printf function. Fixed.
11694 *) mod_digest didn't properly deal with proxy authentication. It
11695 also lacked a case-insensitive comparision of the "Digest"
11696 token. [Ronald Tschalaer <Ronald.Tschalaer psi.ch>] PR#1599
11698 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
11700 *) A few cleanups in mod_info to make it thread-safe, and remove an
11701 off-by-5 bug that could hammer \0 on the stack. [Dean Gaudet]
11703 *) no2slash() was O(n^2) in the length of the input. Make it O(n).
11706 *) API: migration from strncpy() to our "enhanced" version called
11707 ap_cpystrn() for performance and functionality reasons.
11708 Located in libap.a. [Jim Jagielski]
11710 *) table_set() and table_unset() did not deal correctly with
11711 multiple occurrences of the same key.
11712 [Stephen Scheck <sscheck infonex.net>, Ben Laurie] PR#1604
11714 *) The AuthName must now be enclosed in quotes if it is to contain
11715 spaces. [Ken Coar] PR#1195
11717 *) API: new function: ap_escape_quotes(). [Ken Coar] PR#1195
11719 *) WIN32: Work around optimiser bug that killed ISAPI in release
11720 versions. [Ben Laurie] PR#1533
11722 *) PORT: Update the MPE port [Mark Bixby, Jim Jagielski]
11724 *) Interim (slow) fix for p->sub_pool critical sections in
11725 alloc.c (affects win32 only). [Ben Hyde]
11727 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
11729 *) send_fd_length() did not calculate total_bytes_sent properly.
11730 [Ben Reser <breser regnow.com>] PR#1366
11732 *) The bputc() macro was not properly integrated with the chunking
11733 code; in many cases modules using bputc() could cause completely
11734 bogus chunked output. (Typically this will show up as problems
11735 with Internet Explorer 4.0 reading a page, but other browsers
11736 having no problem.) [Dean Gaudet]
11738 *) Create LARGE_WRITE_THRESHOLD define which determines how many
11739 bytes have to be supplied to bwrite() before it will consider
11740 doing a writev() to assemble multiple buffers in one system
11741 call. This is critical for modules such as mod_include,
11742 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
11743 strings in some cases. The result would be extra effort
11744 setting up writev(), and in many cases extra effort building
11745 chunks. The default is 31, it can be overriden at compile
11746 time. [Dean Gaudet]
11748 *) Move the gid switching code into the child so that log files
11749 and pid files are opened with the root gid.
11750 [Gregory A Lundberg <lundberg vr.net>]

11753 instead of counting control characters.
11754 [Jim Patterson <Jim.Patterson Cognos.COM>] PR#1340
11756 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
11757 so the functionality is available to applications other than the

11760 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
11761 the libap consolidation work. [Ken Coar]
11763 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
11764 useful, and isn't what the standards require. Now it returns 0

11866 allocated in the parent, for cleanup in the parent, and resources
11867 which are allocated in each child, for cleanup in each child.
11868 A new pool was created which is passed to the module child_init
11869 and child_exit functions; modules are free to register per-child
11870 cleanups there. This fixes a bug with reliable piped logs.
11873 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
11874 unless it was also doing FancyIndexes, but it displayed the
11875 HeaderName file at the top under all circumstances. It now shows
11876 the ReadmeName file for simple indices, too, as it should.
11879 *) http_core was mmap()ing even in cases where it wasn't going to
11880 read the file. [Ben Hyde <bhyde gensym.com>]
11882 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
11883 Now the rewriting engine (the heart of mod_rewrite) is organized more
11884 straight-forward, first time well documented and reduced to the really
11885 essential parts. All redundant cases were stripped off and processing now
11886 is the same for both per-server and per-directory context with only a
11887 minimum difference (the prefix stripping in per-dir context). As a
11888 side-effect some subtle restrictions and two recently discovered problems
11889 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
11890 context and restrictions on the substitution URL on redirects.
11891 Additionally some minor source cleanups were done.

12048 *) TestCompile was not passing $LIBS [Dean Gaudet]
12050 *) Makefile.tmpl was not using $CFLAGS in the link phase.
12053 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
12054 rudimentary memory debugger which can be used on live servers with
12055 low impact -- it sets all allocated and freed memory bytes to 0xa5.
12056 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
12057 and free() for each object. This is far more expensive and should
12058 only be used for testing with tools such as Electric Fence and
12059 Purify. See main/alloc.c for more details. [Dean Gaudet]
12061 *) Configure uses a sh trap and didn't set its exitcode properly.
12062 [Dean Gaudet] PR#1159
12064 *) Yet another vhost revamp. Add the NameVirtualHost directive which
12065 explicitly lists the ip:port pairs that are to be used for name-vhosts.
12066 From a given ip:port, regardless what the Host: header is, you can
12067 only reach the vhosts defined on that ip:port. The precedence of
12068 vhosts was reversed to match other precedences in the config --
12069 the earlier vhosts override the later vhosts. All vhost matching was
12070 moved into http_vhost.[ch]. [Dean Gaudet]
12072 *) ap_inline can be used to force inlining. GNUC __attribute__() can
12073 be used for whatever reason is appropriate (i.e. format() warnings
12074 for printf style functions). Both are enabled only with
12075 gcc >= 2.7.x (so that we have fewer support issues with older
12076 versions). [Dean Gaudet]
12078 *) Fix support for Proxy Authentication (we were testing the response
12079 status too early). [Marc Slemko]
12081 *) CoreDumpDirectory directive directs where the core file is
12082 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
12083 received. [Marc Slemko, Dean Gaudet]
12085 *) PORT: Support for Atari MINT.
12086 [Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
12088 *) When booting, apache will now detach itself from stdin, stdout,
12089 and stderr. stderr will not be detached until after the config
12090 files have been read so you will be able to see initial error
12091 messages. After that all errors are logged in the error_log.
12092 This makes it more convenient to start apache via rsh, ssh,
12093 or crontabs. [Dean Gaudet] PR#523
12095 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
12096 Also removed the auto-generated link to www.apache.org that was the
12097 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
12099 *) send_fb would not detect aborted connections in some situations.
12102 *) mod_include would use uninitialized data when parsing certain

12105 *) mod_imap should only handle GET methods. [Jay Bloodworth]
12107 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
12109 *) mod_autoindex improperly counted &escapes; as more than one
12110 character in the description. It also improperly truncated
12111 descriptions that were exactly the maximum length.
12114 *) RedirectMatch was not properly escaping the result (PR#1155). Also
12115 "RedirectMatch /advertiser/(.*) $1" is now permitted.
12118 *) mod_include now uses symbolic names to check for request success
12119 and return HTTP errors, and correctly handles all types of
12120 redirections (previously it only did temporary redirect correctly).
12121 [Ken Coar, Roy Fielding]
12123 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
12124 r->filename. Since those two are meant to be in sync with each other
12125 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]

12133 *) Work around problem under Linux where a child will start looping
12134 reporting a select error over and over.
12135 [Rick Franchuk <rickf transpect.net>] PR#1107, 987, 588
12137 *) Fixed error in proxy_util.c when looping through multiple host IP
12138 addresses. [Lars Eilebrecht] PR#974
12140 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
12141 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
12142 bytes before writing, but it will never split a log entry across a
12143 buffer boundary. [Dean Gaudet]
12145 *) API: the short_score record has been split into two pieces, one which
12146 the parent writes on, and one which the child writes on. As part of
12147 this change the get_scoreboard_info() function was removed, and
12148 scoreboard_image was exported. This change fixes a race condition
12149 in file based scoreboard systems, and speeds up changes involving the
12150 scoreboard in earlier 1.3 development. [Dean Gaudet]
12152 *) API: New register_other_child() API (see http_main.h) which allows
12153 modules to register children with the parent for maintenance. It
12154 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
12156 *) API: New piped_log API (see http_log.h) which implements piped logs,
12157 and will use register_other_child to implement reliable piped logs
12158 when it is available. The reliable piped logs part can be disabled
12159 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
12160 logs is only available on Unix. [Dean Gaudet]
12162 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
12163 meets_conditions(). This allows conditional HTTP selection to be
12164 handled separately from the storing of the header fields, and provides
12165 the ability for CGIs to set their own ETags for conditional checking.
12166 [Ken Coar, Roy Fielding] PR#895
12168 *) Changes to mod_log_config to allow naming of format strings.
12169 Format nicknames are defined with "LogFormat fmt nickname", and can
12170 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
12173 *) New module, "mod_speling", which can help find files even when
12174 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
12176 *) API: New function child_terminate() triggers the child process to
12177 exit, while allowing the child finish what it needs to for the
12178 current request first.
12179 [Doug MacEachern, Alexei Kosut]
12181 *) Windows now defaults to using full status reports with mod_status.
12182 [Alexei Kosut] PR #1094
12184 *) *Really* disable all mod_rewrite operations if the engine is off.
12185 Some things (like RewriteMaps) were checked/performed even if they
12186 weren't supposed to be. [Ken Coar] PR #991
12188 *) Implement a new timer scheme which eliminates the need to call alarm() all
12189 the time. Instead a counter in the scoreboard for each child is used to
12190 show when the child has made forward progress. The parent samples this
12191 counter every scoreboard maintenance cycle, and issues SIGALRM if no
12192 progress has been made in the timeout period. This reduces the static
12193 request best-case syscall count to 22 from 29. This scheme is only
12194 used by systems with memory-based scoreboards. [Dean Gaudet]
12196 *) The proxy now properly handles CONNECT requests which are sent
12197 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
12199 *) A script called apachectl has been added to the support
12200 directory. This script allows you to do things such as
12201 "apachectl start" and "apachectl restart" from the command
12202 line. [Marc Slemko]
12204 *) Modules and core routines are now put into libraries, which
12205 simplifies the link line tremendously (among other advantages).
12208 *) Some of the MD5 names defined in Apache have been renamed to have
12209 an `ap_' prefix to avoid conflicts with routines supplied by
12210 external libraries. [Ken Coar]
12212 *) Removal of mod_auth_msql.c from the distribution. There are many
12213 other options for databases today. Rather than offer one option,
12214 offer none at this time. mod_auth_msql and other SQL database
12215 authentication modules can be found at the Apache Module Registry.
12216 http://modules.apache.org/ It would be nice to offer a generic
12217 mod_auth_sql option in the near future.
12219 *) PORT: BeOS support added [Alexei Kosut]
12221 *) Configure no longer accepts the -make option, since it creates
12222 Makefile on the fly based on Makefile.tmpl and Configuration.
12224 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
12225 of forcibly killing off all its processes and exiting without
12226 cleaning up. [Alexei Kosut]
12228 *) API: A new field in the request_rec, r->mtime, has been added to
12229 avoid gratuitous parsing of date strings. It is intended to hold
12230 the last-modified date of the resource (if applicable). An
12231 update_mtime() routine has also been added to advance it if
12232 appropriate. [Roy Fielding, Ken Coar]
12234 *) SECURITY: If a htaccess file can not be read due to bad permissions,
12235 deny access to the directory with a HTTP_FORBIDDEN. The previous
12236 behavior was to ignore the htaccess file if it could not be read.
12237 This change may make some setups with unreadable htaccess files
12238 stop working. [Marc Slemko] PR#817
12240 *) Add aplog_error() providing a mechanism to define levels of
12241 verbosity to the server error logging. This addition also provides
12242 the ability to log errors using syslogd. Error logging is configurable
12243 on a per-server basis using the LogLevel directive. Conversion
12244 of log_*() in progress. [Randy Terbush]
12246 *) Further enhance aplog_error() to not log filename, line number, and
12247 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
12249 *) WIN32: Canonicalise filenames under Win32. Short filenames are
12250 converted to long ones. Backslashes are converted to forward
12251 slashes. Case is converted to lower. Parts of URLs that do not
12252 correspond to files are left completely alone. [Ben Laurie]
12254 *) PORT: 2 new OSs added to the list of ports:
12255 Encore's UMAX V: Arieh Markel <amarkel encore.com>
12256 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
12258 *) Add the server version (SERVER_VERSION macro) to the "server
12259 configured and running" entry in the error_log. Also build an
12260 object file at link-time that contains the current time
12261 (SERVER_BUILT global const char[]), and include that in the
12262 message. [Ken Coar]
12264 *) Set r->headers_out when sending responses from the proxy.
12265 This fixes things such as the logging of headers sent from
12266 the proxy. [Marc Slemko] PR#659
12268 *) support/httpd_monitor is no longer distributed because the
12269 scoreboard should not be file based if at all possible. Use
12270 mod_status to see current server snapshot.
12272 *) (set_file_slot): New function, allowing auth directives to be
12273 independent of the server root, so the server documents can be
12274 moved to a different directory or machine more easily.
12275 [David J. MacKenzie]
12277 *) If no TransferLog is given explicitly, decline
12278 to log. This supports coexistence with other logging modules,
12279 such as the custom one that UUNET uses. [David J. MacKenzie]
12281 *) Check for titles in server-parsed HTML files.
12282 Ignore leading newlines and returns in titles. The old behavior
12283 of replacing a newline after <title> with a space causes the
12284 title to be misaligned in the listing. [David J. MacKenzie]
12286 *) Change mod_cern_meta to be configurable on a per-directory basis.
12287 [David J. MacKenzie]
12289 *) Add 'Include' directive to allow inclusion of configuration
12290 files within configuration files. [Randy Terbush]
12292 *) Proxy errors on connect() are logged to the error_log (nothing
12293 new); now they include the IP address and port that failed
12294 (*that's* new). [Ken Coar, Marc Slemko] PR#352
12296 *) Various architectures now define USE_MMAP_FILES which causes
12297 the server to use mmap() for static files. There are two
12298 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
12299 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
12300 number of bytes written in one cycle from a single mmap()d object,
12301 default 32768). [Dean Gaudet]
12303 *) API: Added post_read_request API phase which is run right after reading
12304 the request from a client, or right after an internal redirect. It is
12305 useful for modules setting environment variables that depend only on
12306 the headers/contents of the request. It does not run during subrequests
12307 because subrequests inherit pretty much everything from the main
12308 request. [Dean Gaudet]
12310 *) Added mod_unique_id which is used to generate a unique identifier for
12311 each hit, available in the environment variable UNIQUE_ID.
12314 *) init_modules is now called after the error logs have been opened. This
12315 allows modules to emit information messages into the error logs.
12318 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
12319 information for case where proxy module is not available. [Marc Slemko]
12321 *) PORT: Apache has need for mutexes to serialize its children around
12322 accept. In prior versions either fcntl file locking or flock file
12323 locking were used. The method is chosen by the definition of
12324 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
12325 and FLOCK for flock(). New options have been added:
12326 - SYSVSEM to use System V style semaphores
12327 - PTHREAD to use POSIX threads (appears to work on Solaris only)
12328 - USLOCK to use IRIX uslock
12329 Based on timing various techniques, the following changes were made
12331 - Linux 2.x uses flock instead of fcntl
12332 - Solaris 2.x uses pthreads
12333 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
12334 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
12335 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
12336 Martijn Koster <m.koster pobox.com>]
12338 *) PORT: The semantics of accept/select make it very desirable to use
12339 mutexes to serialize accept when multiple Listens are in use. But
12340 in the case where only a single socket is open it is sometimes
12341 redundant to serialize accept(). Not all unixes do a good job with
12342 potentially dozens of children blocked on accept() on the same
12343 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
12344 the server will avoid serialization when listening on only one socket,
12345 and use serialization when listening on multiple sockets.
12346 [Dean Gaudet] PR#467
12348 *) Configure changes: TestLib replaced by TestCompile, which has
12349 some additional capability (such as doing a sanity check of
12350 the compiler and flags selected); the version of Solaris is now
12351 available via the #define value of SOLARIS2; IRIX n32bit libs
12352 now supported and selectable by new Configuration Rule: IRIXN32;
12353 We no longer default to -O2 optimization. [Jim Jagielski]
12355 *) Updated Configure: Configuration now uses AddModule to specify
12356 module source or binary file location, relative to src directory.
12357 Modules can be dropped into modules/extra, or in their own
12358 directory, and modules can come with a Makefile or Configure can
12359 create one. Modules can add compiler or library information to
12360 generated Makefiles. [Paul Sutton]
12362 *) Source core re-organisation: distributed modules are now in
12363 modules/standard. All other source code is in main. OS-specific
12364 code is in os/{unix,emx,win32} directories. [Paul Sutton]
12366 *) mod_browser has been removed, since it's replaced by mod_setenvif.
12369 *) Fix another long-standing bug in sub_req_lookup_file where it would
12370 happily skip past access checks on subdirectories looked up with
12371 relative paths. (It's used by mod_dir, mod_negotiation,
12372 and mod_include.) [Dean Gaudet]
12374 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
12375 N is the number of <Directory> sections, and M is the number of
12376 components in the filename of an object.
12378 To achieve this optimization the following config changes were made:
12379 - Wildcards (* and ?, not the regex forms) in <Directory>s,
12380 <Files>s, and <Location>s now treat a slash as a special
12381 character. For example "/home/*/public_html" previously would
12382 match "/home/a/andrew/public_html", now it only matches things
12383 like "/home/bob/public_html". This mimics /bin/sh behaviour.
12384 - It's possible now to use [] wildcarding in <Directory>, <Files>
12386 - Regex <Directory>s are applied after all non-regex <Directory>s.
12390 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
12391 and corrupted paths. [Dean Gaudet]
12393 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
12394 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
12395 be accessed now via backreferences $1..$9 in RewriteConds test-against
12396 strings in addition to RewriteRules subst string. Second the grouped
12397 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
12398 via backreferences %1..%9 both in following RewriteCond test-against
12399 strings and RewriteRules subst string. This provides maximum flexibility
12400 through the use of backreferences.
12401 Additionally the rewriting engine was cleaned up by putting common
12402 code to the new expand_backrefs_inbuffer() function.
12403 [Ralf S. Engelschall]
12405 *) When merging the main server's <Directory> and <Location> sections into
12406 a vhost, put the main server's first and the vhost's second. Otherwise
12407 the vhost can't override the main server. [Dean Gaudet] PR#717
12409 *) The <Directory> code would merge and re-merge the same section after
12410 a match was found, possibly causing problems with some modules.
12413 *) ip-based vhosts are stored and queried using a hashing function, which
12414 has been shown to improve performance on servers with many ip-vhosts.
12415 Some other changes had to be made to accommodate this:
12416 - the * address for vhosts now behaves like _default_
12417 - the matching process now is:
12418 - match an ip-vhost directly via hash (possibly matches main
12420 - if that fails, just pretend it matched the main server
12421 - if so far only the main server has been matched, perform
12422 name-based lookups (ServerName, ServerAlias, ServerPath)
12423 *only on name-based vhosts*
12424 - if they fail, look for _default_ vhosts
12425 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
12427 *) dbmmanage overhaul:
12428 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
12429 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
12430 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
12431 - provide better seed for rand
12432 - prompt for password as per getpass(3) (turn off echo, read from
12434 - use "newstyle" crypt based on $Config{osname} ($^O)
12435 - will not add a user if already in database, use new `update' command
12437 - added `check' command to check a users' password
12438 - added `import' command to convert existing password text-files or
12439 dbm files exported with `view'
12440 - more descriptive usage, general cleanup, 'use strict' clean, etc.
12443 *) Added psocket() which is a pool form of socket(), various places within
12444 the proxy weren't properly blocking alarms while registering the cleanup
12445 for its sockets. bclose() now uses pclose() and pclosesocket(). There
12446 was a bug where the client socket was being close()d twice due a still
12447 registered cleanup. [Dean Gaudet]
12449 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
12452 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
12453 [Jason Venner <jason idiom.com>] PR#667
12455 *) Enable ``=""'' for RewriteCond directives to match against
12456 the empty string. This is the preferred way instead of ``^$''.
12457 [Ralf S. Engelschall]
12459 *) Fixed an infinite loop in mod_imap for references above the server root
12460 [Dean Gaudet] PR#748
12462 *) mod_proxy now has a ReceiveBufferSize directive, similar to
12463 SendBufferSize, so that the TCP window can be set appropriately
12464 for LFNs. [Phillip A. Prindeville]
12466 *) mod_browser has been replaced by the more general mod_setenvif
12467 (courtesy of Paul Sutton). BrowserMatch* directives are still
12468 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
12469 UnSetEnvIfZero directives. [Ken Coar]
12471 *) "HostnameLookups double" forces double-reverse DNS to succeed in
12472 order for remote_host to be set (for logging, or for the env var
12473 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
12476 *) mod_access overhaul:
12477 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
12478 and cidr syntax (i.e. 10.1.0.0/16). PR#762
12479 - Critical path was sped up by pre-computing a few things at config time.
12480 - The undocumented syntax "allow user-agents" was removed,
12481 the replacement is "allow from env=foobar" combined with mod_browser.
12482 - When used with hostnames it now forces a double-reverse lookup
12483 no matter what the directory settings are. This double-reverse
12484 doesn't affect any of the other routines that use the remote
12485 hostname. In particular it's still passed to CGIs and the log
12486 without the double-reverse check. Related PR#860.
12489 *) When a large bwrite() occurs (larger than the internal buffer size),
12490 while there is already something in the buffer, apache will combine
12491 the large write and the buffer into a single writev(). (This is
12492 in anticipation of using mmap() for reading files.)
12495 *) In obscure cases where a partial socket write occurred while chunking,
12496 Apache would omit the chunk header/footer on the next block. Cleaned
12497 up other bugs/inconsistencies in error conditions in buff.c. Fixed
12498 a bug where a long pause in DNS lookups could cause the last packet
12499 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
12501 *) API: Added child_exit function to module structure. This is called
12502 once per "heavy-weight process" just before a server child exit()'s
12503 e.g. when max_requests_per_child is reached, etc.
12504 [Doug MacEachern, Dean Gaudet]
12506 *) mod_include cleanup showed that handle_else was being used to handle
12507 endif. It didn't cause problems, but it was cleaned up too.
12510 *) mod_cern_meta would attempt to find meta files for the directory itself
12511 in some cases, but not in others. It now avoids it in all cases.
12514 *) mod_mime_magic would core dump if there was a decompression error.
12515 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
12517 *) PORT: some variants of DGUX require -lsocket -lnsl
12518 [Alexander L Jones <alex systems-options.co.uk>] PR#732
12520 *) mod_autoindex now allows sorting of FancyIndexed directory listings
12521 by the various fields (name, size, et cetera), either in ascending
12522 or descending order. Just click on the column header. [Ken Coar]
12524 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
12525 CPUs like the Alpha. Apache still stores ints in pointers, but that's
12526 the relatively safe direction. [Dean Gaudet] PR#344
12528 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
12529 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
12531 *) child_main avoids an unneeded call to select() when there is only one
12532 listening socket. [Dean Gaudet]
12534 *) In the event that the server is starved for idle servers it will
12535 spawn 1, then 2, then 4, ..., then 32 servers each second,
12536 doubling each second. It'll also give a warning in the errorlog
12537 since the most common reason for this is a poor StartServers
12538 setting. The define MAX_SPAWN_RATE can be used to raise/lower
12539 the maximum. [Dean Gaudet]
12541 *) Apache now provides an effectively unbuffered connection for
12542 CGI scripts. This means that data will be sent to the client
12543 as soon as the CGI pauses or stops output; previously, Apache would
12544 buffer the output up to a fixed buffer size before sending, which
12545 could result in the user viewing an empty page until the CGI finished
12546 or output a complete buffer. It is no longer necessary to use an
12547 "nph-" CGI to get unbuffered output. Given that most CGIs are written
12548 in a language that by default does buffering (e.g. perl) this
12549 shouldn't have a detrimental effect on performance.
12551 "nph-" CGIs, which formerly provided a direct socket to the client
12552 without any server post-processing, were not fully compatible with
12553 HTTP/1.1 or SSL support. As such they would have had to implement
12554 the transport details, such as encryption or chunking, in order
12555 to work properly in certain situations. Now, the only difference
12556 between nph and non-nph scripts is "non-parsed headers".

12559 *) If a BUFF is switched from buffered to unbuffered reading the first
12560 bread() will return whatever remained in the buffer prior to the
12561 switch. [Dean Gaudet]
12563 Changes with Apache 1.3a1
12565 *) Added another Configure helper script: TestLib. It determines
12566 if a specified library exists. [Jim Jagielski]
12568 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
12569 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
12572 *) PORT: Some architectures use size_t for various lengths in network
12573 functions such as accept(), and getsockname(). The definition
12574 NET_SIZE_T is used to control this. [Dean Gaudet]
12576 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
12577 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
12578 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
12580 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
12581 [Igor N Kovalenko <infoh mail.wplus.net>]
12583 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
12584 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
12585 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
12586 [Dean Gaudet] related PR#875
12588 *) API: Correct child_init() slot declaration from int to void, to
12589 match the init() declaration. Update mod_example to use the new
12592 *) added transport handle slot (t_handle) to the BUFF structure
12595 *) get_client_block() returns wrong length if policy is
12596 REQUEST_CHUNKED_DECHUNK.

12604 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
12606 *) AddModuleInfo directive for mod_info which allows you to annotate
12607 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
12609 *) Added NoProxy directive to avoid using ProxyRemote for selected
12610 addresses. Added ProxyDomain directive to cause unqualified
12611 names to be qualified by redirection.
12612 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
12614 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
12615 header to the remote host in the proxy. [Sameer Parekh and
12618 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
12619 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
12620 URLs, fixed rewritelog(), fixed forced response code handling on
12621 redirects from within .htaccess files, disabled pipe locking under
12622 braindead SunOS 4.1.x, allow env variables to be set even on rules with
12623 no substitution, bugfixed situations where HostnameLookups is off, made
12624 mod_rewrite more thread-safe for NT port and fixed problem when creating
12625 an empty query string via "xxx?".
12626 This update also removes the copyright of Ralf S. Engelschall,
12627 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
12628 exclusively copyrighted by the Apache Group now. This happened because
12629 the author now has gifted mod_rewrite exclusively to the Apache Group and
12630 no longer maintains an external version.
12631 [Ralf S. Engelschall]
12633 *) API: Added child_init function to module structure. This is called
12634 once per "heavy-weight process" before any requests are handled.
12635 See http_config.h for more details. [Dean Gaudet]
12637 *) Anonymous_LogEmail was logging on each subrequest.
12638 [Dean Gaudet] PR#421, 868
12640 *) API: Added is_initial_req() which tests if the request being
12641 processed is the initial request, or a subrequest.
12644 *) Extended SSI (mod_include) now handles additional relops for
12645 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
12647 *) Configure fixed to correctly propagate user-selected options and
12648 settings (such as CC and OPTIM) to Makefiles other than
12649 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
12651 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
12652 directory indices to start with the contents of the HeaderName file
12653 if there is one. If there isn't one, the behaviour is unchanged.
12654 [Ken Coar, Roy Fielding, Andrey A. Chernov]
12656 *) WIN32: Modules can now be dynamically loaded DLLs using the
12657 LoadModule/LoadFile directives. Note that module DLLs must be
12658 compiled with the multithreaded DLL version of the runtime library.
12659 [Alexei Kosut and Ben Laurie]
12661 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
12662 This allows the admin to completely remove automatic indexing
12663 from the server, while still supporting the basic functions of
12664 trailing-slash redirects and DirectoryIndex files. Note that if
12665 you're carrying over an old Configuration file and you use directory
12666 indexing then you'll want to add:
12668 Module autoindex_module mod_autoindex.o
12670 before mod_dir in your Configuration. [Dean Gaudet]
12672 *) popendir/pclosedir created to properly protect directory scanning.
12673 [Dean Gaudet] PR#525
12675 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
12676 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
12677 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
12680 *) The AccessFileName directive can now take more than one filename.
12681 ["Lou D. Langholtz" <ldl usi.utah.edu>]
12683 *) The new mod_mime_magic can be used to "magically" determine the type
12684 of a file if the extension is unknown. Based on the unix file(1)
12685 command. [Ian Kluft <ikluft cisco.com>]
12687 *) We now determine and display the time spent processing a
12688 request if desired. [Jim Jagielski]
12690 *) mod_status: PID field of "dead" child slots no longer displays
12691 main httpd process's PID. [Jim Jagielski]
12693 *) Makefile.nt added - to build all the bits from the command line:
12694 nmake -f Makefile.nt
12695 Doesn't yet work properly. [Ben Laurie]
12697 *) Default text of 404 error is now "Not Found" rather than the
12698 potentially misleading "File Not Found". [Ken Coar]
12700 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
12701 for the net if we require people that actually need this data to
12702 enable it. [Linus Torvalds]
12704 *) directory_walk() is an expensive function, keep a little more state to
12705 avoid needless string counting. Add two new functions make_dirstr_parent
12706 and make_dirstr_prefix which replace all existing uses of make_dirstr.
12707 The new functions are a little less general than make_dirstr, but
12708 work more efficiently (less memory, less string counting).
12711 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
12712 to LDFLAGS) to avoid complications with lex rules in make files.
12713 [Dean Gaudet] PR#372
12715 *) run_method optimized to avoid needless scanning over NULLs in the
12716 module list. [Dean Gaudet]
12718 *) Revamp of (unix) scoreboard management code such that it avoids
12719 unnecessary traversals of the scoreboard on each hit. This is
12720 particularly important for high volume sites with a large
12721 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
12722 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
12723 httpd.h. [Dean Gaudet]
12725 *) In configurations using multiple Listen statements it was possible for
12726 busy sockets to starve other sockets of service. [Dean Gaudet]
12728 *) Added hook so standalone_main can be replaced at compile time
12729 (define STANDALONE_MAIN)
12732 *) Lowest-level read/write functions in buff.c will be replaced with
12733 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
12734 compile time. The default sfio discipline will behave as apache
12735 would without sfio compiled in.
12738 *) Enhance UserDir directive (mod_userdir) to accept a list of
12739 usernames for the 'disable' keyword, and add 'enable user...' to
12740 selectively *en*able userdirs if they're globally disabled.
12743 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
12744 will work with Netscape dbm files. (dbmmanage will probably not
12745 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
12747 *) Add a ListenBacklog directive to control the backlog parameter
12748 passed to listen(). Also change the default to 511 from 512.
12751 *) API: A new handler response DONE which informs apache that the
12752 request has been handled and it can finish off quickly, similar to
12753 how it handles errors. [Rob Hartill]
12755 *) Turn off chunked encoding after sending terminating chunk/footer
12756 so that we can't do it twice by accident. [Roy Fielding]
12758 *) mod_expire also issues Cache-Control: max-age headers.
12761 *) API: Added kill_only_once option for free_proc_chain so that it won't
12762 aggressively try to kill off specific children. For fastcgi.
12763 [Stanley Gambarin <gambarin OpenMarket.com>]
12765 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
12767 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
12768 When used together, these cause mod_dir to emit HEIGHT and WIDTH
12769 attributes in the FancyIndexing IMG tags. [Ken Coar]
12771 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
12773 *) PORT: Added Windows NT support

12776 Changes with Apache 1.2.6

12829 *) It appears the "257th byte" bug (see
12830 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
12831 at the 256th byte as well. Fixed. [Dean Gaudet]
12833 *) mod_rewrite would not handle %3f properly in some situations.
12836 *) Apache could generate improperly chunked HTTP/1.1 responses when
12837 the bputc() or rputc() functions were used by modules (such as
12838 mod_include). [Dean Gaudet]
12840 *) #ifdef wrap a few #defines in httpd.h to make life easier on

12869 properly null terminated. [Marc Slemko]
12871 *) SECURITY: General mod_include cleanup, including fixing several
12872 possible buffer overflows and a possible infinite loop. This cleanup
12873 was done against 1.3 code and then backported to 1.2, the result
12874 is a large difference (due to indentation cleanup in 1.3 code).
12875 Users interested in seeing a smaller set of relevant differences
12876 should consider comparing against src/modules/standard/mod_include.c
12877 from the 1.3b3 release. Non-indentation changes to mod_include
12878 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
12880 *) SECURITY: Numerous changes to mod_imap in a general cleanup
12881 including fixing a possible buffer overflow. This cleanup also
12882 was done with 1.3 code as a basis, see the previous note
12883 about mod_include. [Dean Gaudet]
12885 *) SECURITY: If a htaccess file can not be read due to bad
12886 permissions, deny access to the directory with a HTTP_FORBIDDEN.
12887 The previous behavior was to ignore the htaccess file if it could not
12888 be read. This change may make some setups with unreadable
12889 htaccess files stop working. PR#817 [Marc Slemko]
12891 *) SECURITY: no2slash() was O(n^2) in the length of the input.
12892 Make it O(n). This inefficiency could be used to mount a denial
12893 of service attack against the Apache server. Thanks to

12939 do for errors and cached responses. [Roy Fielding]
12941 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
12943 Changes with Apache 1.2.2 [not released]
12945 *) Fixed another long-standing bug in sub_req_lookup_file where it would
12946 happily skip past access checks on subdirectories looked up with relative
12947 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
12950 *) Add lockfile name to error message printed out when
12951 USE_FLOCK_SERIALIZED_ACCEPT is defined.
12954 *) Enhanced the chunking and error handling inside the buffer functions.
12955 [Dean Gaudet, Roy Fielding]
12957 *) When merging the main server's <Directory> and <Location> sections into
12958 a vhost, put the main server's first and the vhost's second. Otherwise
12959 the vhost can't override the main server. [Dean Gaudet] PR#717
12961 *) The <Directory> code would merge and re-merge the same section after
12962 a match was found, possibly causing problems with some modules.

12966 [Dean Gaudet] PR#748
12968 *) mod_include cleanup showed that handle_else was being used to handle
12969 endif. It didn't cause problems, but it was cleaned up too.
12972 *) Last official synchronization of mod_rewrite with author version (because
12973 mod_rewrite is now directly developed by the author at the Apache Group):
12974 o added diff between mod_rewrite 3.0.6+ and 3.0.9
12975 minus WIN32/NT stuff, but plus copyright removement.

12982 - fix for rewritelog in cases where remote hostname is unknown
12983 - fixed totally damaged request_rec walk-back loop
12984 o remove static from local data and add static to global ones.
12985 o replaced ugly proxy finding stuff by simple
12986 find_linked_module("mod_proxy") call.
12987 o added missing negation char on rewritelog()

12996 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

13017 [Dean Gaudet] PR#832
13019 *) API: In HTTP/1.1, whether or not a request message contains a body
13020 is independent of the request method and based solely on the presence
13021 of a Content-Length or Transfer-Encoding. Therefore, our default
13022 handlers need to be prepared to read a body even if they don't know
13023 what to do with it; otherwise, the body would be mistaken for the
13024 next request on a persistent connection. discard_request_body()
13025 has been added to take care of that. [Roy Fielding] PR#378

13033 Changes with Apache 1.2.1

13041 could contain "../" allowing a local user to "publish" any file on
13042 the system. No slashes are allowed now. [Dean Gaudet]
13044 *) SECURITY: It was possible to violate the symlink Options using mod_dir
13045 (headers, readmes, titles), mod_negotiation (type maps), or
13046 mod_cern_meta (meta files). [Dean Gaudet]
13048 *) SECURITY: Apache will refuse to run as "User root" unless
13049 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
13051 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
13052 if it contained a .htaccess disallowing symlinks. This is contrary
13053 to the rule that symlink permissions are tested with the symlink
13054 options of the parent directory. [Dean Gaudet] PR#353
13056 *) CONFIG: The LockFile directive can be used to place the serializing
13057 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
13058 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
13061 *) Request processing now retains state of whether or not the request
13062 body has been read, so that internal redirects and subrequests will
13063 not try to read it twice (and block). [Roy Fielding]

13075 handle high numbered descriptors (examples include bind, and
13076 solaris libc). On all systems apache attempts to keep all permanent
13077 descriptors above 15 (called the low slack line). Solaris users
13078 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
13079 which keeps all non-FILE * descriptors above 255. On all systems
13080 this should make supporting large numbers of vhosts with many open
13081 log files more feasible. If this causes trouble please report it,
13082 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.

13086 log files are opened. The only known case where this can cause

13144 reading from one buffer and writing to another, at least until it has
13145 a custom timeout handler. [Roy Fielding and Petr Lampa]

13193 we don't want the error message to include those fields. Likewise,
13194 reset the content_language(s) and content_encoding of the response
13195 before generating or redirecting to an error message, since the new

13199 and 304 responses) and err_headers_out (headers sent with all responses).

13216 *) The method for determining PATH_INFO has been restored to the pre-1.2b
13217 (and NCSA httpd) definition wherein it was the extra path info beyond
13218 the CGI script filename. The environment variable FILEPATH_INFO has
13219 been removed, and instead we supply the original REQUEST_URI to any
13220 script that wants to be Apache-specific and needs the real URI path.
13221 This solves a problem with existing scripts that use extra path info
13222 in the ScriptAlias directive to pass options to the CGI script.
13225 *) The _default_ change in 1.2b10 will change the behaviour on configs
13226 that use multiple Listen statements for listening on multiple ports.
13227 But that change is necessary to make _default_ consistent with other
13228 forms of <VirtualHost>. It requires such configs to be modified

13314 parsing of headers. If the terminating empty-line CRLF occurs starting
13315 at the 256th or 257th byte of output, then Navigator will think a normal
13316 image is invalid. We are guessing that this is because their initial
13317 read of a new request uses a 256 byte buffer. We check the bytes written
13318 so far and, if we are about to tickle the bug, we instead insert a
13319 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

13371 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
13374 Changes with Apache 1.2b8
13376 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
13377 to it. [Marc Slemko]
13379 *) The addition of <Location> and <File> directives made the
13380 sub_req_lookup_simple() function bogus, so we now handle
13381 the special cases directly. [Dean Gaudet]
13383 *) We now try to log where the server is dumping core when a fatal
13384 signal is received. [Ken Coar]
13386 *) Improved lingering_close by adding a special timeout, removing the
13387 spurious log messages, removing the nonblocking settings (they
13388 are not needed with the better timeout), and adding commentary
13389 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
13390 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
13392 *) Send error messages about setsockopt failures to the server error
13393 log instead of stderr. [Roy Fielding]
13395 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
13397 *) Stopgap solution for CGI 3-second delay with server-side includes: if
13398 processing a subrequest, allocate memory from r->main->pool instead
13399 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
13400 in the middle of an SSI request. [Dean Gaudet] PR #122
13402 *) Fixed status of response when POST is received for a nonexistent URL
13403 (was sending 405, now 404) and when any method is sent with a
13404 full-URI that doesn't match the server and the server is not acting
13405 as a proxy (was sending 501, now 403). [Roy Fielding]
13407 *) Host port changed to unsigned short. [Ken Coar] PR #276
13409 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
13411 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
13413 *) Report extra info from errno with many errors that cause httpd to exit.
13414 spawn_child, popenf, and pclosef now have valid errno returns in the
13415 event of an error. Correct problems where errno was stomped on
13416 before being reported. [Dean Gaudet]
13418 *) In the proxy, if the cache filesystem was full, garbage_coll() was
13419 never called, and thus the filesystem would remain full indefinitely.
13420 We now also remove incomplete cache files left if the origin server
13421 didn't send a Content-Length header and either the client has aborted
13422 transfer or bwrite() to client has failed. [Petr Lampa]
13424 *) Fixed the handling of module and script-added header fields.
13425 Improved the interface for sending header fields and reduced
13426 the duplication of code between sending okay responses and errors.
13427 We now always send both headers_out and err_headers_out, and
13428 ensure that the server-reserved fields are not being overridden,
13429 while not overriding those that are not reserved. [Roy Fielding]
13431 *) Moved transparent content negotiation fields to err_headers_out
13432 to reflect above changes. [Petr Lampa]
13434 *) Fixed the determination of whether or not we should make the
13435 connection persistent for all of the cases where some other part
13436 of the server has already indicated that we should not. Also
13437 improved the ordering of the test so that chunked encoding will
13438 be set whenever it is desired instead of only when KeepAlive
13439 is enabled. Added persistent connection capability for most error
13440 responses (those that do not indicate a bad input stream) when
13441 accessed by an HTTP/1.1 client. [Roy Fielding]
13443 *) Added missing timeouts for sending header fields, error responses,
13444 and the last chunk of chunked encoding, each of which could have
13445 resulted in a process being stuck in write forever. Using soft_timeout
13446 requires that the sender check for an aborted connection rather than
13447 continuing after an EINTR. Timeouts that used to be initiated before
13448 send_http_header (and never killed) are now initiated only within or
13449 around the routines that actually do the sending, and not allowed to
13450 propagate above the caller. [Roy Fielding]
13452 *) mod_auth_anon required an @ or a . in the email address, not both.
13455 *) per_dir_defaults weren't set correctly until directory_walk for
13456 name-based vhosts. This fixes an obscure bug with the wrong config
13457 info being used for vhosts that share the same ip as the server.
13460 *) Improved generation of modules/Makefile to be more generic for
13461 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
13463 *) Generate makefile dependency for Configuration based on the actual
13464 name given when running the Configure process. [Dean Gaudet]
13466 *) Fixed problem with vhost error log not being set prior to
13467 initializing virtual hosts. [Dean Gaudet]
13469 *) Fixed infinite loop when a trailing slash is included after a type map
13470 file URL (extra path info). [Petr Lampa]
13472 *) Fixed server status updating of per-connection counters. [Roy Fielding]
13474 *) Add documentation for DNS issues (reliability and security), and try
13475 to explain the virtual host matching process. [Dean Gaudet]
13477 *) Try to continue gracefully by disabling the vhost if a DNS lookup
13478 fails while parsing the configuration file. [Dean Gaudet]
13480 *) Improved calls to setsockopt. [Roy Fielding]
13482 *) Negotiation changes: Don't output empty content-type in variant list;
13483 Output charset in variant list; Return sooner from handle_multi() if
13484 no variants found; Add handling of '*' wildcard in Accept-Charset.
13485 [Petr Lampa and Paul Sutton]
13487 *) Fixed overlaying of request/sub-request notes and headers in
13488 mod_negotiation. [Dean Gaudet]
13490 *) If two variants' charset quality are equal and one is the default
13491 charset (iso-8859-1), then prefer the variant that was specifically
13492 listed in Accept-Charset instead of the default. [Petr Lampa]
13494 *) Memory allocation problem in push_array() -- it would corrupt memory
13495 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
13497 *) invoke_handler() doesn't handle mime arguments in content-type
13498 [Petr Lampa] PR#160
13500 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
13503 *) Fixed problem with ErrorDocument not working for virtual hosts
13504 due to one of the performance changes in 1.2b7. [Dean Gaudet]
13506 *) Log an error message if we get a request header that is too long,
13507 since it may indicate a buffer overflow attack. [Marc Slemko]
13509 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
13510 not reject URLs without a double-slash, as per RFC2068 section 3.2.
13511 [Ken Coar] PR #146, #187
13513 *) Added table entry placeholder for new header_parser callback
13514 in all of the distributed modules. [Ken Coar] PR #191
13516 *) Allow for cgi files without the .EXE extension on them under OS/2.
13517 [Garey Smiley] PR #59
13519 *) Fixed error message when resource is not found and URL contains
13520 path info. [Petr Lampa and Dean Gaudet] PR #40
13522 *) Fixed user and server confusion over what should be a virtual host
13523 and what is the main server, resulting in access to something
13524 other than the name defined in the virtualhost directive (but
13525 with the same IP address) failing. [Dean Gaudet]
13527 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
13528 AIX; improves the redirection stuff to enable the users to generally
13529 redirect to http, https, gopher and ftp; added TIME variable for
13530 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
13531 special patterns >STRING, <STRING and =STRING to RewriteCond, which
13532 can be used in conjunction with %{TIME} or other variables to create
13533 time-dependent rewriting rules. [Ralf S. Engelschall]
13535 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
13536 Module authors may need to adjust their code for proper cleanup to take
13537 place (that is, call note_cleanups_for_fd()). This change fixes problems
13538 with file descriptors being erroneously closed when the proxy module was
13539 in use. [Ben Laurie]
13541 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
13542 initgroups() to hose the group information needed for later
13543 comparisons. [Randy Terbush]
13545 *) Remove unnecessary call to va_end() in create_argv() which
13546 caused a SEGV on some systems.
13548 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
13551 *) Clear memory allocated for listeners. [Randy Terbush]
13553 *) Improved handling of IP address as a virtualhost address and
13554 introduced "_default_" as a synonym for the default vhost config.
13555 [Dean Gaudet] PR #212
13557 Changes with Apache 1.2b7
13559 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
13561 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
13563 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
13564 - replace protocol response numbers with symbols
13565 - save variant-list into main request notes
13566 - free allocated memory from subrequests
13567 - merge notes, headers_out and err_headers_out
13569 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
13570 "HTTP/#.# ###*" to be more lenient about what we accept.
13573 *) more proxy FTP bug fixes:
13574 - Changed send_dir() to remove user/passwd from displayed URL.
13575 - Changed login error messages to be more descriptive.
13576 - remove setting of SO_DEBUG socket option
13577 - Make ftp_getrc() more lenient about multiline responses,
13578 specifically, 230 responses which don't have continuation 230-
13579 on each line). These seem to be all NT FTP servers, and while
13580 perhaps questionable, they appear to be legal by RFC 959.
13581 - Add missing kill_timeout() after transfer to user completes.
13584 *) Fixed problem where a busy server could hang when restarting
13585 after being sent a SIGHUP due to child processes not exiting.
13588 *) Modify mod_include escaping so a '\' only signifies an escaped
13589 character if the next character is one that needs
13590 escaping. [Ben Laurie]
13592 *) Eliminated possible infinite loop in mod_imap when relative URLs are
13593 used with a 'base' directive that does not have a '/' in it.
13594 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
13596 *) Reduced the default timeout from 1200 seconds to 300, and the
13597 one in the sample configfile from 400 to 300. [Marc Slemko]
13599 *) Stop vbprintf from crashing if given a NULL string pointer;
13600 print (null) instead. [Ken Coar]
13602 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
13603 [Marc Slemko and Roy Fielding]
13605 *) Fixed problem with mod_cgi-generated internal redirects trying to
13606 read the request message-body twice. [Archie Cobbs and Roy Fielding]
13608 *) Reduced timeout on lingering close, removed possibility of a blocked
13609 read causing the child to hang, and stopped logging of errors if
13610 the socket is not connected (reset by client). [Roy Fielding]
13612 *) Rearranged main child loop to remove duplication of code in
13613 select/accept and keep-alive requests, fixed several bugs regarding
13614 checking scoreboard_image for exit indication and failure to
13615 account for all success conditions and trap all error conditions,
13616 prevented multiple flushes before closing the socket; close the entire
13617 socket buffer instead of just one descriptor, prevent logging of
13618 EPROTO and ECONNABORTED on platforms where supported, and generally
13619 improved readability. [Roy Fielding]
13621 *) Extensive performance improvements. Cleaned up inefficient use of
13622 auto initializers, multiple is_matchexp calls on a static string,
13623 and excessive merging of response_code_strings. [Dean Gaudet]
13625 *) Added double-buffering to mod_include to improve performance on
13626 server-side includes. [Marc Slemko]
13628 *) Several fixes for suexec wrapper. [Randy Terbush]
13629 - Make wrapper work for files on NFS filesystem.
13630 - Fix portability problem of MAXPATHLEN.
13631 - Fix array overrun problem in clean_env().
13632 - Fix allocation of PATH environment variable
13634 *) Removed extraneous blank line is description of mod_status chars.
13637 *) Logging of errors from the call_exec routine simply went nowhere,
13638 since the logfile fd has been closed, so now we send them to stderr.
13639 [Harald T. Alvestrand]
13641 *) Fixed core dump when DocumentRoot is a CGI.
13642 [Ben Laurie, reported by <geddis tesserae.com>]
13644 *) Fixed potential file descriptor leak in mod_asis; updated it and
13645 http_core to use pfopen/pfclose instead of fopen/fclose.
13646 [Randy Terbush and Roy Fielding]
13648 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
13649 as the DEC Alpha which is 64-bit but uses 32-bit ints.
13650 [Dean Gaudet and Ken Coar]
13652 *) Return a 302 response code to the client when sending a redirect
13653 due to a missing trailing '/' on a directory instead of a 301; now
13654 it is cacheable. [Markus Gyger]
13656 *) Fix condition where, if a bad directive occurs in .htaccess, and
13657 sub_request() goes first to this directory, then log_reason() will
13658 SIGSEGV because it doesn't have initialized r->per_dir_config.
13659 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
13661 *) Fix handling of lang_index in is_variant_better(). This was
13662 causing problems which resulted in the server sending the
13663 wrong language document in some cases. [Petr Lampa]
13665 *) Remove free() from clean_env() in suexec wrapper. This was nuking
13666 the clean environment on some systems.
13668 *) Tweak byteserving code (e.g. serving PDF files) to work around
13669 bugs in Netscape Navigator and Microsoft Internet Explorer.
13670 Emit Content-Length header when sending multipart/byteranges.
13673 *) Port to HI-UX/WE2. [Nick Maclaren]
13675 *) Port to HP MPE operating system for HP 3000 machines
13676 [Mark Bixby <markb cccd.edu>]
13678 *) Fixed bug which caused a segmentation fault if only one argument
13679 given to RLimit* directives. [Ed Korthof]
13681 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
13683 *) Improved buffered output to the client by delaying the flush decision
13684 until the BUFF code is actually about to read the next request.
13685 This fixes a problem introduced in 1.2b5 with clients that send
13686 an extra CRLF after a POST request. Also improved chunked output
13687 performance by combining writes using writev() and removing as
13688 many bflush() calls as possible. NOTE: Platforms without writev()
13689 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
13690 or Configure, unless we have already done so. [Dean Gaudet]
13692 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
13694 *) Fixed mod_info output corruption bug introduced by buffer overflow
13695 fixes. [Dean Gaudet]
13697 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
13698 for the special case of a 304 response. [Paul Sutton]
13700 *) Improved handling of TRACE method by bypassing normal method handling
13701 and header parsing routines; fixed Allow response to always allow TRACE.
13704 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
13706 *) Cleaned-up some of the generated HTML. [Ken Coar]
13708 Changes with Apache 1.2b6
13710 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
13712 *) Fix typo introduced in fix for potential infinite loop around
13713 accept() in child_main(). This change caused the rev to 1.2b6.
13714 1.2b5 was never a public beta.
13716 Changes with Apache 1.2b5
13718 *) Change KeepAlive semantics (On|Off instead of a number), add
13719 MaxKeepAliveRequests directive. [Alexei Kosut]
13721 *) Various NeXT compilation patches, as well as a change in
13722 regex/regcomp.c since that file also used a NEXT define.
13725 *) Allow * to terminate the end of a directory match in mod_dir.
13726 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
13728 *) Don't call can_exec() if suexec_enabled. Calling this requires
13729 scripts executed by the suexec wrapper to be world executable, which
13730 defeats one of the advantages of running the wrapper. [Randy Terbush]
13732 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
13735 *) Migration from sprintf() to snprintf() to avoid buffer
13736 overflows. [Marc Slemko]
13738 *) Provide portable snprintf() implementation (ap_snprintf)
13739 as well as *cvt family. [Jim Jagielski]
13741 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
13744 *) Remove mod_fastcgi.c from the distribution. This module appears
13745 to be maintained more through the Open Market channels and should
13746 continue to be easily available at http://www.fastcgi.com/
13748 *) Fixed bug in modules/Makefile that wouldn't allow building in more
13749 than one subdirectory (or cleaning, either). [Jeremy Laidman]
13751 *) mod_info assumed that the config files were relative to ServerRoot.
13754 *) CGI scripts called as an error document resulting from failed
13755 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
13757 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
13760 *) Properly check errno to prevent display of a directory index
13761 when server receives a long enough URL to confuse stat().
13764 *) Several security enhancements to suexec wrapper. It is _highly_
13765 recommended that previously installed versions of the wrapper
13766 be replaced with this version. [Randy Terbush, Jason Dour]
13768 - ~user execution now properly restricted to ~user's home
13769 directory and below.
13770 - execution restricted to UID/GID > 100
13771 - restrict passed environment to known variables
13772 - call setgid() before initgroups() (portability fix)
13773 - remove use of setenv() (portability fix)
13775 *) Add HTTP/1.0 response forcing. [Ben Laurie]
13777 *) Add access control via environment variables. [Ben Laurie]
13779 *) Add rflush() function. [Alexei Kosut]
13781 *) remove duplicate pcalloc() call in new_connection().
13783 *) Fix incorrect comparison which could allow number of children =
13784 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
13785 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
13787 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
13788 AIX PS/2, CONVEXOS. [Jim Jagielski]
13790 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
13791 It's more portable. [Martin Kraemer]
13793 *) Replace references to make in Makefile.tmpl with $(MAKE).
13796 *) Add ProxyBlock directive w/IP address caching. Add IP address
13797 caching to NoCache directive as well. ProxyBlock works with all
13798 handlers; NoCache now also works with FTP for anonymous logins.
13799 Still more code cleanup. [Chuck Murcko]
13801 *) Add "header parse" API hook [Ben Laurie]
13803 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
13805 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
13807 *) Correctly allow access and auth directives in <Files> sections in
13808 server config files. [Alexei Kosut]
13810 *) Fix bug with ServerPath that could cause certain files to be not
13811 found by the server. [Alexei Kosut]
13813 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
13814 double-quote from text and so that it properly checks for unsupported
13815 status codes using the new index_of_response interface. [Roy Fielding]
13817 *) Multiple fixes to the lingering_close code in order to avoid being
13818 interrupted by a stray timeout, to avoid lingering on a connection
13819 that has already been aborted or never really existed, to ensure that
13820 we stop lingering as soon as any error condition is received, and to
13821 prevent being stuck indefinitely if the read blocks. Also improves
13822 reporting of error conditions. [Marc Slemko and Roy Fielding]
13824 *) Fixed initialization of parameter structure for sigaction.
13825 [<mgyger itr.ch>, Adrian Filipi-Martin]
13827 *) Fixed reinitializing the parameters before each call to accept and
13828 select, and removed potential for infinite loop in accept.
13829 [Roy Fielding, after useful PR from <adrian virginia.edu>]
13831 *) Fixed condition where, if a child fails to fork, the scoreboard would
13832 continue to say SERVER_STARTING forever. Eventually, the main process
13833 would refuse to start new children because count_idle_servers() will
13834 count those SERVER_STARTING entries and will always report that there
13835 are enough idle servers. [Phillip Vandry]
13837 *) Fixed bug in bcwrite regarding failure to account for partial writes.
13838 Avoided calling bflush() when the client is pipelining requests.
13839 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
13841 *) Added description of "." mode in server-status [Jim Jagielski]
13843 Changes with Apache 1.2b4
13845 *) Fix possible race condition in accept_mutex_init() that
13846 could leave a small security hole open allowing files to be
13847 overwritten in cases where the server UID has write permissions.
13850 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
13852 *) Fix portablity problem in util_script where ARG_MAX may not be
13853 defined for some systems.
13855 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
13858 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
13859 style magic #! token for better script portability. [Garey Smiley]
13861 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
13862 execution for ~userdir CGI. [Jason Dour]
13864 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
13866 *) Fix month off by one in suexec wrapper logging.
13868 Changes with Apache 1.2b3:
13870 *) Fix error in mod_cgi which could cause resources not to be properly
13871 freed, or worse. [Dean Gaudet]
13873 *) Fix find_string() NULL pointer dereference. [Howard Fear]
13875 *) Add set_flag_slot() at the request of Dirk and others.
13878 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
13880 *) Add changes to improve the error message given for invalid
13881 ServerName parameters. [Dirk vanGulik]
13883 *) Add "Authoritative" directive for Auth modules that don't
13884 currently have it. This gives admin control to assign authoritative
13885 control to an authentication scheme and allow "fall through" for
13886 those authentication modules that aren't "Authoritative" thereby
13887 allowing multiple authentication mechanisms to be chained.
13890 *) Remove requirement for ResourceConfig/AccessConfig if not using
13891 the three config file layout. [Randy Terbush]
13893 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
13895 *) Changes to suexec wrapper to fix the following problems:
13896 1. symlinked homedirs will kill ~userdirs.
13897 2. initgroups() on Linux 2.0.x clobbers gr->grid.
13898 3. CGI command lines paramters problems
13899 4. pw-pwdir for "docroot check" still the httpd user's pw record.
13900 [Randy Terbush, Jason Dour]
13902 *) Change create_argv() to accept variable arguments. This fixes
13903 a problem where arguments were not getting passed to the CGI via
13904 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
13906 *) Collapse multiple slashes in path URLs to properly apply
13907 handlers defined by <Location>. [Alexei Kosut]
13909 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
13911 *) Improve the accuracy of request duration timings by setting
13912 r->request_time in read_request_line() instead of read_request().
13915 *) Reset timeout while reading via get_client_block() in mod_cgi.c
13916 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
13918 *) Add the ability to pass different Makefile.tmpl files to Configure
13919 using the -make flag. [Rob Hartill]
13921 *) Fix coredump triggered when sending a SIGHUP to the server caused
13922 by an assertion failure, in turn caused by an uninitialised field in a
13926 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
13927 PATH_INFO from previous versions of Apache (in certain situations,
13928 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
13929 [later removed in 1.2b11]
13931 *) Add rwrite() function to API to allow for sending strings of
13932 arbitrary length. [Doug MacEachern]
13934 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
13936 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
13937 NeXT. [Jim Jagielski]
13939 *) Removed recent modification to promote the status code on internal
13940 redirects, since the correct fix was to change the default log format
13941 in mod_log_config so that it outputs the original status. [Rob Hartill]
13943 Changes with Apache 1.2b2:
13945 *) Update set_signals() to use sigaction() for setting handlers.
13946 This appears to fix a re-entrant problem in the seg_fault()
13947 bus_error() handlers. [Randy Terbush]
13949 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
13951 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
13953 *) proxy_http.c bugfixes: [Chuck Murcko]
13954 1) fixes possible NULL pointer reference w/NoCache
13955 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
13956 host would cache nothing if it was in the local domain,
13957 and the local domain was in the NoCache list)
13958 3) Adds Host: header when not available
13959 4) Some code cleanup and clarification
13961 *) mod_include.c bugfixes:
13962 1) Fixed an ommission that caused include variables to not
13963 be parsed in config errmsg directives [Howard Fear]
13964 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
13965 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
13966 4) Allow backslash-escaping to all quoted text
13967 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
13968 5) Pass variable to command line if not set in XSSI's env
13971 *) Fix infinite loop when processing Content-language lines in
13972 type-map files. [Alexei Kosut]
13974 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
13976 *) Fixed problem in set_[user|group] that prevented CGI execution
13977 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
13979 *) Added PORTING information file. [Jim Jagielski]
13981 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
13983 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
13985 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
13986 USE_FCNTL_SERIALIZED_ACCEPT was intended.
13988 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
13989 which caused problems of systems where socket s_addr is >32bits.
13991 *) Added comment to explain (r->chunked = 1) side-effect in
13992 http_protocol.c [Roy Fielding]
13994 *) Replaced use of index() in mod_expires.c with more appropriate
13995 and portable isdigit() test. [Ben Laurie]
13997 *) Updated Configure for ...
13998 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
13999 *-dg-dgux* (bad pattern match)
14000 QNX (DEF_WANTHSREGEX=yes)
14001 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
14003 *-unixware211 (new)
14004 and added some user diagnostic info. [Ben Laurie]
14006 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
14007 for better portability. [Jim Jagielski]
14009 *) Updated helpers/GuessOS for ...
14010 SCO 5 (recognize minor releases)
14011 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
14012 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
14013 IRIX64 (-sgi-irix64)
14014 ULTRIX (-unknown-ultrix)
14015 SINIX (-whatever-sysv4)
14016 NCR Unix (-ncr-sysv4)
14017 and fixed something in helpers/PrintPath [Ben Laurie]
14019 Changes with Apache 1.2b1
14021 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
14023 Changes with Apache 1.1.1
14025 *) Fixed bug where Cookie module would make two entries in the
14026 logfile for each access [Mark Cox]
14028 *) Fixed bug where Redirect in .htaccess files would cause memory
14029 leak. [Nathan Neulinger]
14031 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
14033 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
14035 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
14037 Changes with Apache 1.1.0
14039 *) Bring NeXT support up to date. [Takaaki Matsumoto]
14041 *) Bring QNX support up to date. [Ben Laurie]
14043 *) Make virtual hosts default to main server keepalive parameters.
14044 [Alexei Kosut, Ben Laurie]
14046 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
14048 *) Fix missing address family for connect, also remove unreachable statement
14049 in mod_proxy. [Ben Laurie]
14051 *) mod_env now turned on by default in Configuration.tmpl.
14053 *) Bugs which were fixed:
14054 a) yet more mod_proxy bugs [Ben Laurie]
14055 b) CGI works again with inetd [Alexei Kosut]
14056 c) Leading colons were stripped from passwords [<osm interguide.com>]
14057 d) Another fix to multi-method Limit problem [<jk tools.de>]
14059 Changes with Apache 1.1b4
14061 *) r->bytes_sent variable restored. [Robert Thau]
14063 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
14065 *) More possibly unsecure programs removed from the support directory.
14067 *) More mod_auth_msql authentication improvements.
14069 *) VirtualHosts based on Host: headers no longer conflict with the
14072 *) OS/2 compatibility enhancements. [Gary Smiley]
14074 *) POST now allowed to directory index CGI scripts.
14076 *) Actions now work with files of the default type.
14078 *) Bugs which were fixed:
14079 a) more mod_proxy bugs
14080 b) early termination of inetd requests
14081 c) compile warnings on several systems
14082 d) problems when scripts stop reading output early
14084 Changes with Apache 1.1b3
14086 *) Much of cgi-bin and all of cgi-src has been removed, due to
14087 various security holes found and that we could no longer support
14090 *) The "Set-Cookie" header is now special-cased to not merge multiple
14091 instances, since certain popular browsers can not handle multiple
14092 Set-Cookie instructions in a single header. [Paul Sutton]
14094 *) rprintf() added to buffer code, occurrences of sprintf removed.
14097 *) CONNECT method for proxy module, which means tunneling SSL should work.
14098 (No crypto needed) Also a NoCache config directive.
14100 *) Several API additions: pstrndup(), table_unset() and get_token()
14101 functions now available to modules.
14103 *) mod_imap fixups, in particular Location: headers are now complete
14106 *) New "info" module which reports on installed module set through a
14107 special URL, a la mod_status.
14109 *) "ServerPath" directive added - allows for graceful transition
14110 for Host:-header-based virtual hosts.
14112 *) Anonymous authentication module improvements.
14114 *) MSQL authentication module improvements.
14116 *) Status module design improved - output now table-based. [Ben Laurie]
14118 *) htdigest utility included for use with digest authentication
14121 *) mod_negotiation: Accept values with wildcards to be treated with
14122 less priority than those without wildcards at the same quality
14123 value. [Alexei Kosut]
14125 *) Bugs which were fixed:
14126 a) numerous mod_proxy bugs
14127 b) CGI early-termination bug [Ben Laurie]
14128 c) Keepalives not working with virtual hosts
14129 d) RefererIgnore problems
14130 e) closing fd's twice in mod_include (causing core dumps on
14131 Linux and elsewhere).
14133 Changes with Apache 1.1b2
14136 a) core dumps in mod_digest
14137 b) truncated hostnames/ip address in the logs
14138 c) relative URL's in mod_imap map files
14140 Changes with Apache 1.1b1
14142 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
14144 Changes with Apache 1.0.3
14146 *) Internal redirects which occur in mod_dir.c now preserve the
14147 query portion of a request (the bit after the question mark).
14150 *) Escape active characters '<', '>' and '&' in html output in
14151 directory listings, error messages and redirection links.
14154 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
14156 *) Fix for POSIX compliance in waiting for processes in alloc.c.
14159 *) setsockopt no longer takes a const declared argument [Martijn Koster]
14161 *) Reset timeout timer after each successful fwrite() to the network.
14162 This patch adds a reset_timeout() procedure that is called by
14163 send_fd() to reset the timeout ever time data is written to the net.
14166 *) timeout() signal handler now checks for SIGPIPE and reports
14167 lost connections in a more user friendly way. [Rob Hartill]
14169 *) Location of the "scoreboard" file which used to live in /tmp is
14170 now configurable (for OSes that can't use mmap) via ScoreBoardFile
14171 which works similar to PidFile (in httpd.conf) [Rob Hartill]
14173 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
14175 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
14176 which caused a SEGV with cookies enabled
14178 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
14181 *) Log the UNIX textual error returned by some system calls, in
14182 particular errors from accept() [David Robinson]
14184 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
14186 Changes with Apache 1.0.2
14188 *) patch to get Apache compiled on UnixWare 2.x, recommended as
14189 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
14191 *) Fix get_basic_auth_pw() to set the auth_type of the request.
14194 *) past changes to http_config.c to only use the
14195 setrlimit function on systems defining RLIMIT_NOFILE
14196 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
14197 for SUNOS and prototypes the needed functions.
14199 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
14202 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
14204 *) Merge multiple headers from CGI scripts instead of taking last
14205 one. [David Robinson]
14207 *) Add support for SCO 5. [Ben Laurie]
14209 Changes with Apache 1.0.1
14211 *) Silence mod_log_referer and mod_log_agent if not configured
14214 *) Recursive includes can occur if the client supplies PATH_INFO data
14215 and the server provider uses relative links; as file.html
14216 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
14218 *) The replacement for initgroups() did not call {set,end}grent(). This
14219 had two implications: if anything else used getgrent(), then
14220 initgroups() would fail, and it was consuming a file descriptor.
14223 *) On heavily loaded servers it was possible for the scoreboard to get
14224 out of sync with reality, as a result of a race condition.
14225 The observed symptoms are far more Apaches running than should
14226 be, and heavy system loads, generally followed by catastrophic
14227 system failure. [Ben Laurie]
14229 *) Fix typo in license. [David Robinson]
14231 Changes with Apache 1.0.0 23 Nov 1995
14233 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
14235 Changes with Apache 0.8.16 05 Nov 1995
14237 *) New man page for 'httpd' added to support directory [David Robinson]
14239 *) .htgroup files can have more than one line giving members for a
14240 given group (each must have the group name in front), for NCSA
14241 back-compatibility [Robert Thau]
14243 *) Mutual exclusion around accept() is on by default for SVR4 systems
14244 generally, since they generally can't handle multiple processes in
14245 accept() on the same socket. This should cure flaky behavior on
14246 a lot of those systems. [David Robinson]
14248 *) AddType, AddEncoding, and AddLanguage directives take multiple
14249 extensions on a single command line [David Robinson]
14251 *) UserDir can be disabled for a given virtual host by saying
14252 "UserDir disabled" in the <VirtualHost> section --- it was a bug
14253 that this didn't work. [David Robinson]
14255 *) Compiles on QNX [Ben Laurie]
14257 *) Corrected parsing of ctime time format [David Robinson]
14259 *) httpd does a perror() before exiting if it can't log its pid
14260 to the PidFile, to make diagnosing the error a bit easier.
14263 *) <!--#include file="..."--> can no longer include files in the
14264 parent directory, for NCSA back-compatibility. [David Robinson]
14266 *) '~' is *not* escaped in URIs generated for directory listings
14269 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
14271 *) Fixed bug involving handling URIs with escaped %-characters
14272 in redirects [David Robinson]
14274 Changes with Apache 0.8.15 14 Oct 1995
14276 *) Switched to new, simpler license
14278 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
14280 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
14282 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
14284 *) Correctly handles internal redirects to files with names containing '%'
14287 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
14289 *) Use geteuid() rather than getuid() to see if we have root privilege,
14290 so that server correctly resets privilege if run setuid root. [Andrew
14293 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
14296 *) Fix relative URLs in imagemap files [Randy Terbush]
14298 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
14301 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
14302 entries all name the same one. [David Robinson]
14304 *) Fix directory listings with filenames containing unusual characters
14307 *) Better URI-escaping for generated URIs in directories with filenames
14308 containing unusual characters [Ben Laurie]
14310 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
14312 *) Unblock alarms on error return from spawn_child() [David Robinson]
14314 *) Sample Config files have extra note for SCO users [Ben Laurie]
14316 *) Configuration has note for HP-UX users [Rob Hartill]
14318 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
14320 *) Nuked bogus #define in httpd.h [David Robinson]
14322 *) Better test for whether a system has setrlimit() [David Robinson]
14324 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
14326 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
14329 Changes with Apache 0.8.14 19 Sep 1995
14331 *) Compiles on SCO ODT 3.0 [Ben Laurie]
14333 *) AddDescription works (better) [Ben Laurie]
14335 *) Leaves an intelligible error diagnostic when it can't set group
14336 privileges on standalone startup [Andrew Wilson]
14338 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
14339 that machine, which claims to be BSD but does not support RLIMIT.
14342 *) gcc -Wall no longer complains about an unused variable when util.c
14343 is compiled with -DMINIMAL_DNS [Andrew Wilson]
14345 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
14347 Changes with Apache 0.8.13 07 Sep 1995
14349 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
14351 *) Have built-in imagemap code recognize & honor Point directive [James
14354 *) Generate cleaner directory listings in directories with a mix of
14355 long and short filenames [Rob Hartill]
14357 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
14359 *) Properly default ServerName for virtual servers [Robert Thau]
14361 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
14362 Paul Richards and a cast of thousands...]
14364 *) On self-identified BSD systems (we don't try to guess any more),
14365 allocate a few extra file descriptors per virtual host with setrlimit,
14366 if we can, to avoid running out. [Randy Terbush]
14368 *) Write 22-character lock file name into buffer with enough space
14369 on startup [Konstantin Olchanski]
14371 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
14374 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
14376 *) Suppress -Wall warning by initializing variable in negotiation code
14377 [Tobias Weingartner]
14379 Changes with Apache 0.8.12 31 Aug 1995
14381 *) Doesn't pause three seconds after including a CGI script which is
14382 too slow to die off (this is done by not even trying to kill off
14383 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
14384 after the entire document has been processed). [Robert Thau]
14386 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
14388 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
14390 *) Allows .htaccess files to override <Directory> sections naming the
14391 same directory [David Robinson]
14393 *) Removed an efficiency hack in sub_req_lookup_uri which was
14394 causing certain extremely marginal cases (e.g., ScriptAlias of a
14395 *particular* index.html file) to fail. [David Robinson]
14397 *) Doesn't log an error when the requested URI requires
14398 authentication, but no auth header line was supplied by the
14399 client; this is a normal condition (the client doesn't no auth is
14400 needed here yet). [Robert Thau]
14402 *) Behaves more sanely when the name server loses its mind [Sean Welch]
14404 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
14406 *) RFC931 code no longer passes out name of prior clients on current
14407 requests if the current request came from a server that doesn't
14408 do RFC931. [David Robinson]
14410 *) Configuration script accepts "Module" lines with trailing whitespace.
14413 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
14415 *) Cleaned up comments in mod_cgi.c [Robert Thau]
14417 Changes with Apache 0.8.11 24 Aug 1995
14419 *) Wildcard <Directory> specifications work. [Robert Thau]
14421 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
14423 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
14424 the file being requested itself, in addition to the directories leading
14425 up to it. [Robert Thau]
14427 *) Logs access failures due to symlink checks or invalid client address
14428 in the error log [Roy Fielding, Robert Thau]
14430 *) Symlink checks deal correctly with systems where lstat of
14431 "/path/to/some/link/" follows the link. [Thau, Fielding]
14433 *) Doesn't reset DirectoryIndex to 'index.html' when
14434 other directory options are set in a .htaccess file. [Robert Thau]
14436 *) Clarified init code and nuked bogus warning in mod_access.c
14437 [Florent Guillaume]
14439 *) Corrected several directives in sample srm.conf
14440 --- includes corrections to directory indexing icon-related directives
14441 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
14442 icons for encodings right, and turning on AddEncoding by default).
14445 *) Corrected descriptions of args to AddIcon and AddAlt in command table
14448 *) INSTALL & README mention "contributed modules" directory [Brian
14451 *) Fixed English in the license language... "for for" --> "for".
14454 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
14455 mod_alias.c, merging it almost completely with handling of Alias, and
14456 adding a 'notes' field to the request_rec which allows the CGI module
14457 to discover whether the Alias module has put this request through
14458 ScriptAlias (which it needs to know for back-compatibility, as the old
14459 NCSA code did not check Options ExecCGI in ScriptAlias directories).
14462 Changes with Apache 0.8.10 18 Aug 1995
14464 *) AllowOverride applies to the named directory, and not just
14465 subdirectories. [David Robinson]
14467 *) Do locking for accept() exclusion (on systems that need it)
14468 using a special file created for the purpose in /usr/tmp, and
14469 not the error log; using the error log causes real problems
14470 if it's NFS-mounted; this is known to be the cause of a whole
14471 lot of "server hang" problems with Solaris. [David Robinson;
14472 thanks to Merten Schumann for help diagnosing the problem].
14474 Changes with Apache 0.8.9 12 Aug 1995
14476 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
14478 *) Nested includes see environment variables of the including document,
14479 for NCSA bug-compatibility (some sites have standard footer includes
14480 which try to print out the last-modified date). [Eric Hagberg/Robert
14483 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
14484 URI as a CGI script, even if it would have been treated as something
14485 else if requested directly, for NCSA back-compatibility. (Note that
14486 this means that people who know the name of the script can see the
14487 code just by asking for it). [Robert Thau]
14489 *) New version of dbmmanage script included in support directory as
14492 *) Check if scoreboard file couldn't be opened, and say so, rather
14493 then going insane [David Robinson]
14495 *) POST to CGI works on A/UX [Jim Jagielski]
14497 *) AddIcon and AddAlt commands work properly [Rob Hartill]
14499 *) NCSA server push works properly --- the Arena bug compatibility
14500 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
14501 if you still want the workaround). [Rob Hartill]
14503 *) If client didn't submit any Accept-encodings, ignore encodings in
14504 content negotiation. (NB this will all have to be reworked anyway
14505 for the new HTTP draft). [Florent Guillaume]
14507 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
14509 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
14511 *) Give Redirect priority over Alias, for NCSA bug compatibility
14514 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
14515 paralleling earlier bug fix for CGI [David Robinson]
14517 *) If DBM auth is improperly configured, report a server error and don't
14520 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
14521 it seems to work well enough without it (even in a 10 hits/sec
14522 workout), and the overhead for the locking under A/UX is
14523 alarmingly high (though it is very low on other systems).
14524 [Eric Hagberg, Jim Jagielski]
14526 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
14528 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
14529 Behlendorf/Eric Hagberg]
14531 *) More improvements to default Configuration for A/UX [Jim Jagielski]
14533 *) Compiles clean on NEXT [Rob Hartill]
14535 *) Compiles clean on SGI [Robert Thau]
14537 Changes with Apache 0.8.8 08 Aug 1995
14539 *) SunOS library prototypes now never included unless explicitly
14540 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
14541 people using GNU libc on SunOS are screwed by prototypes for the
14544 (Those who wish to compile clean with gcc -Wall on a standard
14545 SunOS setup need the prototypes, and may obtain them using
14546 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
14547 with nonstandard libraries are presumably competent to make their
14550 *) Strips trailing '/' characters off both args to the Alias command,
14551 to make 'Alias /foo/ /bar/' work.
14553 Changes with Apache 0.8.7 03 Aug 1995
14555 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
14556 [reported by David Robinson]
14558 *) Compiles clean on OSF/1 [David Robinson]
14560 *) Added some of the more recent significant changes (AddLanguage stuff,
14561 experimental LogFormat support) to CHANGES file in distribution root
14564 Changes with Apache 0.8.6 02 Aug 1995
14566 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
14567 (If you actually wanted a conditional GET which bypassed the cache, you
14568 couldn't get it). [Reported by Roy Fielding]
14570 *) Properly terminate headers on '304 Not Modified' replies to conditional
14571 GETs --- no browser we can find cares much, but the CERN proxy chokes.
14572 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
14574 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
14576 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
14577 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
14578 and older versions don't set the __SUNPRO_C preprocessor variable). On
14579 all other systems, these are never used anyway. [Reported by Mark Cox].
14581 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
14583 Changes with Apache 0.8.5 01 Aug 1995
14585 *) Added last-minute configurable log experiment, as optional module
14587 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
14588 properly. (One-line fix to http_protocol.c).
14590 *) Work around bogus behavior when reloading from Netscape.
14591 It's Netscape's bug --- for some reason they expect a request with
14592 If-modified-since: to not function as a conditional GET if it also
14593 comes with Pragma: no-cache, which is way out of line with the HTTP
14594 spec (according to Roy Fielding, the redactor).
14596 *) Added parameter to set maximum number of server processes.
14598 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
14601 *) IdentityCheck bugfix [Chuck Murcko].
14603 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
14605 *) More sample config file corrections; add extension to AddType for
14606 *.asis, move AddType generic description to its proper place, and
14607 fix miscellaneous typos. [ Alexei Kosut ]
14609 *) Deleted the *other* reference to the regents from the Berkeley
14610 legal disclaimer (everyplace).
14612 *) Nuked Shambhala name from src/README; had already cleaned it out
14613 of everywhere else.
14615 Changes with Apache 0.8.4
14617 *) Changes to server-pool management parms --- renamed current
14618 StartServers to MinSpareServers, created separate StartServers
14619 parameter which means what it says, and renamed MaxServers to
14620 MaxSpareServers (though the old name still works, for NCSA 1.4
14621 back-compatibility). The old names were generally regarded as
14622 too confusing. Also altered "docs" in sample config files.
14624 *) More improvements to default config files ---
14625 sample directives (commented out) for XBitHack, BindAddress,
14626 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
14627 defaults, AddTypes for send-as-is and imagemap magic types, and
14628 improvements to samples for DirectoryIndex [Alexei Kosut]
14630 *) Yet more improvements to default config files --- changes to
14631 Alexei's sample AddLanguage directives, and sample LanguagePriority
14632 [ Florent Guillaume ]
14634 *) Set config file locations properly if not set in httpd.conf
14637 *) Don't escape URIs in internal redirects multiple times; don't
14638 do that when translating PATH_INFO to PATH_TRANSLATED either.
14641 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
14643 Changes with Apache 0.8.3
14645 *) Edited distribution README to *briefly* summarize installation
14646 procedures, and give a pointer to the INSTALL file in the src/
14649 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
14650 recent NCSA distributions.
14652 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
14653 exist for the same directory, use both and don't segfault. [Reported
14656 *) Proper makefile dependencies [David Robinson]
14658 *) Note (re)starts in error log --- reported by Rob Hartill.
14660 *) Only call no2slash() after get_path_info() has been done, to
14661 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
14662 reported by Andrew Wilson, though this one is probably a real bug]
14664 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
14665 dump core when Referer is not supplied. [Randy Terbush]
14667 *) Lightly edited sample config files to refer people to our documentation
14668 instead of NCSA's, and to list Rob McCool as *original* author (also
14669 deleted his old, and no doubt non-functional email address). Would be
14670 nice to have examples of new features...
14672 Changes with Apache 0.8.2 19 Jul 1995
14674 *) Added AddLanuage code [Florent Guillaume]
14676 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
14678 *) All sorts of problems when MultiViews finds a directory. It would
14679 be nice if mod_dir.c was robust enough to handle that, but for now,
14680 just punt. [reported by Brian Behlendorf]
14682 *) Wait for all children on restart, to make sure that the old socket
14683 is gone and we can reopen it. [reported by Randy Terbush]
14685 *) Imagemap module is enabled in default Configuration
14687 *) RefererLog and UserAgentLog modules properly default the logfile
14690 *) Mark Cox's mod_cookies added to the distribution as an optional
14691 module (commented out in the default Configuration, and noted as
14692 an experiment, along with mod_dld). [Mark Cox]
14694 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
14696 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
14698 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
14700 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
14703 Changes with Apache 0.8.1
14705 *) New imagemap module [Randy Terbush]
14707 *) Replacement referer log module with NCSA-compatible RefererIgnore
14708 [Matthew Gray again]
14710 *) Don't mung directory listings with very long filenames.
14711 [Florent Guillaume]
14713 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
14715 *) New config script. See INSTALL for info. [Robert Thau]
14717 *) Scoreboard mechanism for regulating the number of extant server
14718 processes. MaxServers and StartServers defaults are the same as
14719 for NCSA, but the meanings are slightly different. (Actually,
14720 I should probably lower the MaxServers default to 10).
14722 Before asking for a new connection, each server process checks
14723 the number of other servers which are also waiting for a
14724 connection. If there are more than MaxServers, it quietly dies
14725 off. Conversely, every second, the root, or caretaker, process
14726 looks to see how many servers are waiting for a new connection;
14727 if there are fewer than StartServers, it starts a new one. This
14728 does not depend on the number of server processes already extant.
14729 The accounting is arranged through a "scoreboard" file, named
14730 /tmp/htstatus.*, on which each process has an independent file
14731 descriptor (they need to seek without interference).
14733 The end effect is that MaxServers is the maximum number of
14734 servers on an *inactive* server machine, but more will be forked
14735 off to handle unusually heavy loads (or unusually slow clients);
14736 these will die off when they are no longer needed --- without
14737 reverting to the overhead of full forking operation. There is a
14738 hard maximum of 150 server processes compiled in, largely to
14739 avoid forking out of control and dragging the machine down.
14740 (This is arguably too high).
14742 In my server endurance tests, this mechanism did not appear to
14743 impose any significant overhead, even after I forced it to put the
14744 scoreboard file on a normal filesystem (which might have more
14745 overhead than tmpfs). [Robert Thau]
14747 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
14750 *) Read .htaccess files even in directory with <Directory> section.
14751 (Former incompatibility noted on mailing list, now fixed). [Robert
14754 *) "HEAD /" gives the client a "Bad Request" error message, rather
14755 than trying to send no body *and* no headers. [Cliff Skolnick].
14757 *) Don't produce double error reports for some very obscure cases
14758 mainly involving auth configuration (the "all modules decline to
14759 handle" case which is a sure sign of a server bug in most cases,
14760 but also happens when authentication is badly misconfigured).
14763 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
14764 it's *for*, and this sort of thing really shouldn't be cluttering
14765 up the Makefile). [Robert Thau]
14767 *) Incidental code cleanups in http_main.c --- stop dragging
14768 sa_client around; just declare it where used. [Robert Thau]
14770 *) Another acc-related fix. (It doesn't like const char
14771 in some places...). [Mark Cox]
14773 Changes with Shambhala 0.6.1 13 Jul 1995
14775 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
14776 Also, fixed auth typo in http_protocol.c unmasked by this fix.
14778 *) Compiles clean with acc on SunOS [Paul Sutton]
14780 *) Reordered modules in modules.c so that Redirect takes priority
14781 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
14782 believe it or not, he has an actual site with a ScriptAlias and
14783 a Redirect declared for the *exact same directory*. Even *my*
14784 compatibility fetish wouldn't motivate me to fix this if the fix
14785 required any effort, but it doesn't, so what the hey.
14787 *) Fixed to properly default several server_rec fields for virtual
14788 servers from the corresponding fields in the main server_rec.
14789 [Cliff Skolnick --- 'port' was a particular irritant].
14791 *) No longer kills off nph- child processes before they are
14792 finished sending output. [Matthew Gray]
14794 Changes with Shambhala 0.6.0 10 Jul 1995
14796 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
14797 the connection to the client in an "aborted" state, but otherwise
14798 allow whatever handlers are running to clean up. hard_timeout()s
14799 abort the request in progress completely; anything not tied to some
14800 resource pool cleanup will leak. They're still around because I
14801 haven't yet come up with a more elegant way of handling
14802 timeouts when talking to something that isn't the client. The
14803 default_handler and the dir_handler now use soft timeouts, largely
14804 so I can test the feature. [Robert Thau]
14806 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
14807 the case of log handlers dying prematurely is probably handled VERY
14808 gracelessly at this point, and if the logger stops reading input,
14809 the server will hang. (It is known to correctly restart the
14810 logging process on server restart; this is (should be!) going through
14811 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
14812 script). [Robert Thau]
14814 *) asis files supported (new module). [Robert Thau]
14816 *) IdentityCheck code is compiled in, but has not been tested. (I
14817 don't know anyone who runs identd). [Robert Thau]
14819 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
14820 came in with the request, for NCSA bug-compatibility. [Robert Thau]
14822 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
14824 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
14825 as timeouts are not in scope. [Robert Thau]
14827 *) quoted-string args in config files now handled correctly (doesn't drop
14828 the last character). [Robert Thau; reported by Randy Terbush]
14830 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
14831 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
14833 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
14834 default default type); the former default default behavior when all
14835 type-checkers defaulted had been a core dump. [Paul Sutton]
14837 *) Copy filenames out of the struct dirent when indexing
14838 directories. (On Linux, readdir() returns a pointer to the same
14839 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
14841 Changes with Shambhala 0.5.3 [not released]
14843 *) Default response handler notes "file not found" in the error log,
14844 if the file was not found. [Cliff Skolnick].
14846 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
14847 code no longer sets up bogus PATH_INFO which fakes out the directory
14848 handler). [Cliff Skolnick]
14850 Changes with Shambhala 0.5.2 06 Jul 1995
14852 *) Changes to http_main.c --- root server no longer plays silly
14853 games with SIGCHLD, and so now detects and replaces dying
14854 children. Child processes just die on SIGTERM, without taking
14855 the whole process group with them. Potential problem --- if any
14856 child process refuses to die, we hang in restart.
14857 MaxRequestsPerChild may still not work, but it certainly works
14858 better than it did before this! [Robert Thau]
14860 *) mod_dir.c bug fixes: ReadmeName and HeaderName
14861 work (or work better, at least); over-long description lines
14862 properly terminated. [Mark Cox]
14864 *) http_request.c now calls unescape_url() more places where it
14865 should [Paul Sutton].
14867 *) More directory handling bugs (reported by Cox)
14868 Parent Directory link is now set correctly. [Robert Thau]
14870 Changes with Shambhala 0.5.1 04 Jul 1995
14872 *) Generalized cleanup interface in alloc.c --- any function can be
14873 registered with alloc.c as a cleanup for a resource pool;
14874 tracking of files and file descriptors has been reimplemented in
14875 terms of this interface, so I can give it some sort of a test.
14878 *) More changes in alloc.c --- new cleanup_for_exec() function,
14879 which tracks down and closes all file descriptors which have been
14880 registered with the alloc.c machinery before the server exec()s a
14881 child process for CGI or <!--#exec-->. CGI children now get
14882 started with exactly three file descriptors open. Hopefully,
14883 this cures the problem Rob H. was having with overly persistent
14884 CGI connections. [Robert Thau]
14886 *) Mutual exclusion around the accept() in child_main() --- this is
14887 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
14888 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
14889 This uses fcntl(F_SETLK,...) on the error log descriptor because
14890 flock() on that descriptor won't work on systems which have BSD
14891 flock() semantics, including (I think) Linux 1.3 and Solaris.
14893 This does work on SunOS (when the server is idle, only one
14894 process in the pool is waiting on accept()); it *ought* to work
14895 on the other systems. [Robert Thau]
14897 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
14899 *) sizeof(*sa_client) bugfix from [Rob Hartill]
14901 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
14903 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
14904 be unnecessary if I go to the revised timeout-handling scheme).
14907 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
14908 string) even if none came in with the request. [Robert Thau]
14910 *) CHANGES file added to distribution ;-).
14912 Changes with Shambhala 0.4.5
14914 *) mod_dld --- early dynamic loading support [rst]
14915 *) Add wildcard content handlers for XBITHACK; default_hander now
14916 invoked with that mechanism (as a handler hanging off mod_core) [rst]
14917 *) XBITHACK supported as a wildcard content-handler, and
14918 configurable at run-time (not just at compile time, as in the
14919 "patchy server" releases) [rst]
14921 Changes with Shambhala 0.4.4 30 Jun 1995
14923 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
14924 *) Handle Addtype x/y .z [rst, reported by Cox]
14926 Changes with Shambhala 0.4.3
14928 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
14929 synonymous [rst, terbush]
14931 Changes with Shambhala 0.4.1 28 Jun 1995
14933 *) First-cut virtual host implementation; some refit in the config
14934 reading code, and log management, was necessary to support this [rst]
14935 *) Sub-pool machinery, originally added to avoid excessive storage
14936 allocation on listings of large directories (which turned out to
14937 be the problem that the 0.3 storage accounting was added to
14938 find). Subrequests and mod_dir changed to use subpools. [rst]
14939 *) More memory debugging --- free list consistency checks. [rst]
14940 *) Added err_headers to request_rec, with support elsewhere [rst]
14941 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
14943 Changes with Shambhala 0.3 19 Jun 1995
14945 *) Switch ONE_PROCESS to a runtime command-line option (-X)
14946 *) Don't compile in mod_ai_backcompat by default
14947 *) Switch name of server from Apache to Shambhala in Makefile
14948 *) Add some accounting routines to track memory usage in the pools,
14951 Changes with Shambhala 0.2
14953 *) Set DOCUMENT_ROOT CGI variable
14954 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
14955 *) Add critical section protection to handling of cleanup structures
14957 *) Significant code reorg within the server core to group related
14958 functions together [rst]
14959 *) Correctly handle clients that hang up before sending any request
14961 *) Replace dying child processes. [rst]
14963 Changes with Shambhala 0.1 12 Jun 1995
14965 Major rewrite of the pre-existing "patchy server" codebase, by
14966 Robert Thau (rst). Significant portions of the server code, such
14967 as configuration-file handling and HTTP authentication support,
14968 were ripped out and rewritten from scratch. Code that was not
14969 completely rewritten was significantly altered.
14971 Major changes with this release include:
14973 *) Introduction of the module API; in request handling, the central
14974 machinery just dispatches to various modules, which actually do
14975 most of the work. Configuration handling is similar --- modules
14976 declare their own commands, and the central machinery just
14977 dispatches to them.
14979 API features from shambhala/0.1 were substantially unchanged in
14980 Apache 1.0 and 1.1. (1.0 API features not yet present in this
14981 release, such as wildcard handlers and subpools, were added in
14982 subsequent Shambhala releases, and were also generally rst's
14985 *) This release included the following modules:
14987 mod_access (access control --- allow and deny directives),
14988 mod_alias (Alias and Redirect commands),
14989 mod_auth (straight HTTP authentication, based on flat-files)
14990 mod_auth_dbm (same, with dbm files)
14991 mod_cgi (CGI scripts and, in this release, ScriptAlias)
14992 mod_common_log (CLF access logs; later renamed mod_log_common)
14993 mod_dir (directory indexing)
14994 mod_include (server-side includes)
14995 mod_mime (AddType directives)
14996 mod_negotiation (content negotiation)
14997 mod_userdir (support for users' public_html directories)
14999 It also included a mod_ai_backcompat, which was a private hack
15000 for back-compatibility with rst's own AI-lab servers.
15002 All of these modules were substantially complete, and functional
15003 or nearly so (a few, which implemented features not in use at
15004 Thau's site, required patches of a few lines).
15006 *) sub-request machinery, to allow modules to determine how other
15007 modules would assign MIME types to a given file, or optionally
15008 serve its content (this is heavily used by mod_dir, mod_include
15009 and mod_negotiation).
15011 *) Resource pool system for keeping track of memory allocated and
15012 files opened in service of a particular request. Much of the
15013 code in the modules (when they weren't rewrites) was adjusted to
15014 replace a pervasive convention of using fixed-size buffers on
15015 the stack with an equally pervasive convention of using memory
15016 allocated with palloc().
15018 *) Reorganization of data structures associated with a given
15019 request to eliminate use of global variables and the troublesome
15020 unmunge_name function (used in NCSA and early Apache releases to
15021 attempt to determine the URI which mapped to a given filename
15022 --- a difficult proposition, given that it is easy to produce
15023 setups in which multiple URIs map to the same file).
15025 *) Source files renamed and rearranged
15027 *) Very simple pre-forking behavior --- parent process forked off a
15028 fixed number of children, and then just waited for SIGHUP.
15030 *) Other more minor changes too numerous to list.
15032 This release included modified versions of a lot of code from the
15033 Apache 0.6.4 public release, plus an early pre-forking patch
15034 codeveloped by Robert Thau and Rob Hartill.
15036 Changes with Apache 0.7.3 20 Jun 1995
15038 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
15039 were incorporated by Rob Hartill on the main branch while Robert Thau
15040 worked on the Shambhala rewrite above. Most were merged into the
15041 Shambala architecture after Apache 0.8.0.
15043 Changes with Apache 0.6.4 13 May 1995
15045 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
15048 Changes with Apache 0.5.1 10 Apr 1995
15050 Changes with Apache 0.4 02 Apr 1995
15052 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
15055 Changes with Apache 0.3 24 Mar 1995
15057 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
15060 Changes with Apache 0.2 18 Mar 1995
15062 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
15063 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
15064 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
