2 Changes with Apache 2.3.0
3 [Remove entries to the current 2.0 and 2.2 section below, when backported]
5 *) mod_proxy: Fix KeepAlives not being allowed and set to
6 backend servers. PR 38602. [Ruediger Pluem, Jim Jagielski]
8 *) Correctly initialize mod_proxy workers, which use a
9 combination of local and shared datasets. Adjust logging
10 to better trace usage. PR 38403. [Jim Jagielski]
12 *) Respect GracefulShutdownTimeout in the worker and event MPMs.
13 [Chris Darroch <chrisd pearsoncmg.com>, Garrett Rooney]
15 *) mod_proxy_balancer: Do not overwrite the status of initialized workers and
16 respect the configured status of uninitilized workers when creating a new
17 child process. [Ruediger Pluem]
19 *) mod_speling: Stop crashing with certain non-file requests. [Jeff Trawick]
21 *) mod_proxy_ajp: Support common headers of the AJP protocol in responses.
22 PR 38340. [Aleksey Pesternikov <apesternikov yahoo.com>]
24 *) core: Reject invalid Expect header immediately. PR 38123.
27 *) Authz: Add the new module mod_authn_core that will provide common
28 authn directives such as 'AuthType', 'AuthName'. Move the directives
29 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
30 into mod_authn_core. [Brad Nicholes]
32 *) Authz: Mark the directives 'Order', 'Allow', 'Deny' and 'Satisfy' as
33 deprecated and move them into the new module mod_access_compat which
34 can be loaded to provide backwards compatibility for these directives.
37 *) Authz: Move the 'Require' directive from the core module as well as
38 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
39 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
40 logic into the authorization processing. [Brad Nicholes]
42 *) Authz: Add the new module mod_authz_core which acts as the
43 authorization provider vector and contains common authz
44 directives. [Brad Nicholes]
46 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
47 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
49 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
50 host-based access control provided by mod_authz_host and invoked
51 through the 'Require' directive. [Brad Nicholes]
53 *) Authz: Convert all of the authz modules from hook based to
54 provider based. [Brad Nicholes]
56 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
57 seconds to cache a document.
58 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]

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

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

141 Changes with Apache 2.2.0
143 *) mod_negotiation: Minor performance tweak by reusing already calculated
145 [Ruediger Pluem, Christophe Jaillet <christophe.jaillet wanadoo.fr>]
147 *) Remove support for 'On' and 'Off' for AuthBasicProvider and
148 AuthDigestProvider. [Joshua Slive, Justin Erenkrantz]
150 *) Add in new UseCanonicalPhysicalPort directive, which controls
151 whether or not Apache will ever use the actual physical port
152 when constructing the canonical port number. [Jim Jagielski]
154 *) mod_dav: Fix a null pointer dereference in an error code path during the
156 [Ruediger Pluem, Ghassan Misherghi <ghassanm ucdavis.edu>]
158 *) Fix DESTDIR=... installation when using bundled copy of APR.
159 [Torsten Foertsch <torsten.foertsch gmx.net>]
161 *) mod_proxy_balancer: When finding best worker, use case insensitive
162 match for scheme and host, but case sensitive for the rest of

168 sending it up the filter chain. PR37100. [Ruediger Pluem]
170 *) mod_cache: Create new filters CACHE_OUT_SUBREQ / CACHE_SAVE_SUBREQ which
171 only differ by the type from CACHE_OUT / CACHE_SAVE to ensure that
172 subrequests to non local resources work again. [Ruediger Pluem]
174 *) mod_proxy: Do not lowercase the entire worker name of a BalancerMember
175 since this breaks case sensitive URI's. PR36906. [Ruediger Pluem]
177 *) core: AddOutputFilterByType is ignored for proxied requests. PR31226.
178 [Joe Orton, Ruediger Pluem]
180 *) mod_proxy_http: Prevent data corruption of POST request bodies when
181 client accesses proxied resources with SSL. PR37145.
182 [Ruediger Pluem, William Rowe]
184 *) mod_proxy_balancer: BalancerManager and proxies correctly handle
185 member workers with paths. PR36816. [Ruediger Pluem, Jim Jagielski]
187 *) mod_log_config: %{hextid}P will log the thread id in hex with APR

203 [William Barker <william.barker wilshire.com>, Ruediger Pluem]
205 *) Elimiated the NET_TIME filter, restructuring the timeout logic.
206 This provides a working mod_echo on all platforms, and ensures any
207 custom protocol module is at least given an initial timeout value
208 based on the <VirtualHost > context's Timeout directive.
211 *) mod_proxy: Run the request_status hook also if there are no free workers
212 or all workers are in error state.
213 [Ruediger Pluem, Brian Akins <brian.akins turner.com>]

2823 *) Fix a core dump in mod_cache when it attemtped to store uncopyable
2824 buckets. This happened, for instance, when a file to be cached
2825 contained SSI tags to execute a CGI script (passed as a pipe
2826 bucket). [Paul J. Reder]
2828 *) Ensure that output already available is flushed to the network
2829 when the content-length filter realizes that no new output will
2830 be available for a while. This helps some streaming CGIs as
2831 well as some other dynamically-generated content. [Jeff Trawick]

2864 properly for virtual hosts that override server-wide mod_cache
2865 setttings. [Matthieu Estrade <estrade-m ifrance.com>]
2867 *) Add -p option to apxs to allow programs to be compiled with apxs.

2891 and remove the noise on stderr during config dir processing.
2892 [Joe Orton <jorton redhat.com>]
2894 *) mod_cache: cache_storage.c. Add the hostname and any request
2895 args to the key generated for caching. This provides a unique
2896 key for each virtual host and for each request with unique
2897 args. [Paul J. Reder, args code provided by Kris Verbeeck]
2899 *) mod_cache: Do not cache responses to GET requests with query

2939 PR 12132,12181,12172.
2940 [Ian Holsman / Rob Cromwell <apachechangelog robcromwell.com>]
2942 *) The content-length filter no longer tries to buffer up
2943 the entire output of a long-running request before sending
2944 anything to the client. [Brian Pane]
2946 *) Win32: Lower the default stack size from 1MB to 256K. This will
2947 allow around 8000 threads to be started per child process.
2948 'EDITBIN /STACK:size apache.exe' can be used to change this
2949 value directly in the apache.exe executable.
2952 *) Win32: Implement ThreadLimit directive in the Windows MPM.
2955 *) Remove CacheOn config directive since it is set but never checked.
2956 No sense wasting cycles on unused code. Besides, the only truly
2957 bug free code is deleted code. :) [Paul J. Reder]
2959 *) BufferLogs are now run-time enabled, and the log_config now has 2 new
2960 callbacks to allow a 3rd party module to actually do the writing of the
2961 log file [Ian Holsman]

2976 *) Change mod_rewrite to use apr-util's dbm support for dbm rewrite
2977 maps. The dbm type (e.g., ndbm, gdbm) can be specified on the
2978 RewriteMap directive. PR 10644 [Jeff Trawick]
2980 *) Fixed mod_rewrite's RewriteMap prg: support so that request/response

2997 *) thread safety & proxy-ftp [Alexey Panchenko <alexey liwest.ru>, Ian Holsman]
2999 *) mod_disk_cache works much better. This module should still
3000 be considered experimental. [Eric Prud'hommeaux]
3002 *) Performance improvement for keepalive requests: when setting
3003 aside a small file for potential concatenation with the next
3004 response on the connection, set aside the file descriptor rather
3005 than copying the file into the heap. [Brian Pane]
3007 *) Modified version check on openssl so that it finds the executable
3008 first and then performs a check of the version, only warning the
3009 user if they chose, or we selected, an old version of OpenSSL.
3010 This change also allows the code to work for non-openssl libraries
3011 selected via the --with-ssl=dir option, which can override the
3012 automated library check in any case. [Roy Fielding]
3014 Changes with Apache 2.0.40
3016 *) SECURITY: CVE-2002-0661 (cve.mitre.org)
3017 Close a very significant security hole that
3018 applies only to the Win32, OS2 and Netware platforms. Unix was not
3019 affected, Cygwin may be affected. Certain URIs will bypass security
3020 and allow users to invoke or access any file depending on the system
3021 configuration. Without upgrading, a single .conf change will close
3022 the vulnerability. Add the following directive in the global server
3023 httpd.conf context before any other Alias or Redirect directives;
3024 RedirectMatch 400 "\\\.\."
3025 Reported by Auriemma Luigi <bugtest sitoverde.com>.
3028 *) SECURITY: CVE-2002-0654 (cve.mitre.org)
3029 Close a path-revealing exposure in multiview type
3030 map negotiation (such as the default error documents) where the
3031 module would report the full path of the typemapped .var file when
3032 multiple documents or no documents could be served based on the mime
3033 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
3036 *) SECURITY: CVE-2002-0654 (cve.mitre.org)
3037 Close a path-revealing exposure in cgi/cgid when we
3038 fail to invoke a script. The modules would report "couldn't create
3039 child process /path-to-script/script.pl" revealing the full path
3040 of the script. Reported by Jim Race <jrace qualys.com>.
3043 *) Set aside the apr-iconv and apr_xlate() features for the Win32
3044 build of 2.0.40 so development can be completed. A patch, from
3045 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
3046 will be available for those that wish to work with apr-iconv.
3049 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
3050 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
3052 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
3053 set to 1, so we can exclude things from the general case with
3054 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
3056 *) Accept multiple leading /'s for requests within the DocumentRoot.
3057 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
3059 *) Solved the reports of .pdf byterange failures on Win32 alone.
3060 APR's sendfile for the win32 platform collapses header and trailer
3061 buffers into a single buffer. However, we destroyed the pointers
3062 to the header buffer if a trailer buffer was present. PR 10781
3065 *) mod_ext_filter: Add the ability to enable or disable a filter via
3066 an environment variable. Add the ability to register a filter of
3067 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
3069 *) Restore the ability to specify host names on Listen directives.
3070 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh yahoo.com>]
3072 *) When deciding on the default address family for listening sockets,
3073 make sure we can actually bind to an AF_INET6 socket before
3074 deciding that we should default to AF_INET6. This fixes a startup
3075 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
3077 *) Replace usage of atol() to parse strings when we might want a
3078 larger-than-long value with apr_atoll(), which returns long long.
3079 This allows HTTPD to deal with larger files correctly.
3080 [Shantonu Sen <ssen apple.com>]
3082 *) mod_ext_filter: Ignore any content-type parameters when checking if
3083 the response should be filtered. Previously, "intype=text/html"
3084 wouldn't match something like "text/html;charset=8859_1".
3087 *) mod_ext_filter: Set up environment variables for external programs.
3088 [Craig Sebenik <craig netapp.com>]
3090 *) Modified the HTTP_IN filter to immediately append the EOS (end of
3091 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
3092 the caller to determine that no content remains without prefetching
3093 additional POST body. [William Rowe]
3095 *) Get proxy ftp to work over IPv6. [Shoichi Sakane <sakane kame.net>]
3097 *) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml suse.de>]
3099 *) Update SuSE layout. [Peter Poeml <poeml suse.de>]
3101 *) Changes to the internationalized error documents:
3102 Comment them out in the default config file to make the default
3103 install as simple as possible; Correct the english 500 error to
3104 be more understandable; Add a Swedish translation.
3105 [Thomas Sjogren <thomas northernsecurity.net>,
3106 Erik Abele <erik codefaktor.de>, Rich Bowen, Joshua Slive]
3108 *) Increase the limit on file descriptors per process in apachectl.
3111 *) Fix a dependency error when building ApacheMonitor, so that Win32
3112 and MSVC now trust that the project is current (when it is).
3113 [James Cox <imajes php.net>]
3115 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
3116 [Arthur P. Smith <apsmith aps.org>, Jeff Trawick]
3118 *) APR-Util Renames pending have been completed [Thom May]
3120 *) Performance improvements for the code that reads request
3121 headers (ap_rgetline_core() and related functions) [Brian Pane]
3123 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
3124 to configure the maximum amount of memory the allocators will
3125 hold on to for reuse. Anything over the MaxMemFree threshold
3126 will be free()d. This directive is useful when uncommon large
3127 peaks occur in memory usage. It should _not_ be used to mask
3128 defective modules' memory use. [Sander Striker]
3130 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
3131 scripts would not result in a truncated response.
3132 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
3134 *) Add a filter_init parameter to the filter registration functions
3135 so that a filter can execute arbitrary code before the handlers
3136 are invoked. This resolves a problem where mod_include requests
3137 would incorrectly return a 304. [Justin Erenkrantz]
3139 *) Fix a long-standing bug in 2.0, CGI scripts were being called
3140 with relative paths instead of absolute paths. Apache 1.3 used
3141 absolute paths for everything except for SuExec, this brings back
3142 that standard. [Ryan Bloom]
3144 *) Fix infinite loop due to two HTTP_IN filters being present for
3145 internally redirected requests. PR 10146. [Justin Erenkrantz]
3147 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
3150 *) Fix mod_ext_filter to look in the main server for filter definitions
3151 when running in a vhost if the filter definition is not found in
3152 the vhost. PR 10147 [Jeff Trawick]
3154 *) Support WinNT CGI invocation through ScriptInterpreterSource
3155 'registry' for script interpreter paths and names with non-ascii
3156 characters in the executable filepath. [William Rowe]
3158 *) Support the -w flag on to keep the Win32 console open on error.
3161 *) Normalize the hostname value in the request_rec to all-lowercase
3162 [Perry Harrington <pedward webcom.com>]
3164 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
3165 extended characters (non US-ASCII) in non-utf8 format. This brings
3166 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
3167 to the cgi application itself. [William Rowe]
3169 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
3170 modules to bring them up to the current apr/apr-util APIs.
3173 *) Fix segfault in mod_mem_cache most frequently observed when
3174 serving the same file to multiple clients on an MP machine.
3177 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
3178 [Brian Degenhardt <bmd mp3.com>, Ian Holsman]
3180 *) Fix perchild to work with apachectl by adding -k support to perchild.
3181 PR 10074 [Jeff Trawick]
3183 *) Fix a silly htpasswd.c logic error that incorrectly reported that
3184 both -c and -n had been used. PR 9989 [Cliff Woolley]
3186 *) Fixed a mod_include error case in which no HTTP response was sent
3187 to the client if an shtml document contained an unterminated SSI
3188 directive [Brian Pane]
3190 *) Improve ap_get_client_block implementation by using APR-util brigade
3191 helper functions and relying on current filter assumptions.
3194 Changes with Apache 2.0.39
3196 *) Fixed a build problem in htpasswd.c on Win32.
3197 [Guenter Knauf <eflash gmx.net>, Cliff Woolley]
3199 Changes with Apache 2.0.38
3201 *) Rewrite htpasswd to use APR. The removes the annoying warning about
3202 tmpnam being unsafe. [Ryan Bloom]
3204 *) We must set the MIME-type for .shtml files to text/html if we want them
3205 to be parsed for SSI tags. Add the config for that to the default
3206 config file so that it is easier to enable .shtml parsing.
3207 [Dave Dyer <ddyer real-me.net>]
3209 *) Fixed a problem with 'make install' on ReliantUnix.
3210 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
3212 *) Make the default_handler catch all requests that aren't served by
3213 another handler. This also gets us to return a 404 if a directory
3214 is requested, there is no DirectoryIndex, and mod_autoindex isn't
3215 loaded. [Justin Erenkrantz]
3217 *) Fixed the handling of nested if-statements in shtml files.
3218 PR 9866 [Brian Pane]
3220 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
3221 into a directory different from the one that was configured. This
3222 also mirrors the root= feature from 1.3. We cannot use prefix=,
3223 because both APR and APR-util resolve their installation paths at
3224 configuration time. This means that there is no variable prefix
3225 to replace. [Andreas Hasenack <andreas netbank.com.br>]
3227 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
3228 These levels of AIX don't have a thundering herd problem with
3229 accept(). [Jeff Trawick]
3231 *) prefork MPM: Ignore mutex errors during graceful restart. For
3232 certain types of mutexes (particularly SysV semaphores), we
3233 should expect to occasionally fail to obtain or release the
3234 mutex during restart processing. [Jeff Trawick]
3236 *) Fix install-bindist.sh so that it finds any perl instead of just
3237 early perl 5.x versions. This is consistent with a build/install
3238 from source, and it allows the perl scripts installed by a bindist
3239 to work on systems with perl 5.6. [Jeff Trawick]
3241 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
3242 Tru64 (and probably some other platforms). [Jeff Trawick]
3244 *) Allow CGI scripts to return their Content-Length. This also fixes a
3245 hang on HEAD requests seen on certain platforms (such as FreeBSD).
3248 *) Added log rotation based on file size to the RotateLog support
3249 utility. [Brad Nicholes]
3251 *) Fix some casting in mod_rewrite which broke random maps.
3252 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
3254 Changes with Apache 2.0.37
3256 *) allow POST method over SSL when per-directory client cert
3257 authentication is used with 'SSLOptions +OptRenegotiate' enabled
3258 and a client cert was found in the ssl session cache.
3260 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
3261 session cache when there is no cert chain in the cache. prior to
3262 the fix this situation would result in a FORBIDDEN response and
3263 error message "Cannot find peer certificate chain"
3266 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
3267 one was already sent. PR 9644 [Jeff Trawick]
3269 *) Fix the display of the default name for the mime types config
3270 file. PR 9729 [Matthew Brecknell <mbrecknell orchestream.com>]
3272 *) Fix the working directory *for WinNT/2K/XP services only* to

3274 of Apache.exe, in the case that Apache.exe resides in bin/.)
3275 Solves the case of ServerRoot /foo paths where /foo was not
3276 on the same drive as /winnt/system32. [William Rowe]
3278 *) Make 2.0's "AcceptMutex" startup message now "completely"
3279 match how 1.3 does it. [Jim Jagielski]
3281 *) Implement a fixed size memory cache using a priority queue
3284 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
3285 querying certain other variables from config_vars.mk. PR 9316
3288 *) Added the "detached" attribute to the cgi_exec_info_t internals
3289 so that Win32 and Netware won't create a new window or console
3290 for each CGI invoked. PR 8387
3291 [Brad Nicholes, William Rowe]
3293 *) Consolidated the command line parameters and attributes that are
3294 manipulated by the optional function ap_cgi_build_command() in
3295 mod_cgi into a single structure.
3298 *) Get rid of uninitialized value errors with "apxs -q" on certain
3299 variables. [Stas Bekman <stas stason.org>]
3301 *) Fix apxs to allow it to work when the build directory is somewhere
3302 besides server-root/build. PR 8453
3303 [Jeff Trawick and a host of others]
3305 *) Allow ap_discard_request_body to be called multiple times in the
3306 same request. Essentially, ap_http_filter keeps track of whether
3307 it has sent an EOS bucket up the stack, if so, it will only ever
3308 send an EOS bucket for this request.
3309 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
3311 *) Remove all special mod_ssl URIs. This also fixes the bug where
3312 redirecting (.*) will allow an SSL protected page to be viewed
3313 without SSL. [Ryan Bloom]
3315 *) Fix the binary build install script so that the build logic
3316 created by "apxs -g" will work when the user has a binary
3317 build. [Jeff Trawick]
3319 *) Allow instdso.sh to work with full paths to the shared module.
3322 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
3323 in module for NetWare [Brad Nicholes]
3325 *) Changed cgi and piped log behavior to accept 65536 characters
3326 on Win32 (matching Linux) before deadlocking between outputing
3327 client stdin, slurping the output from stdout and then the stderr
3328 stream. PR 8179 [William Rowe]
3330 *) Fixed Win32 wintty.exe support to assure the window title is valid.
3331 Elimiates possible gpfault or garbage title without the -t option.
3334 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
3335 brigades and input filters. [Justin Erenkrantz]
3337 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
3338 body. [Justin Erenkrantz]
3340 *) NetWare: Piping log entries through RotateLogs using the
3341 CustomLogs directive is finally supported now that we have
3342 the pipes and spawning functionality working.

3360 *) Ensure that apr_brigade_write() flushes in all of the cases that
3361 it should to avoid conditions in some modules that could cause
3362 large amounts of data to be buffered. [Cliff Woolley]
3364 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
3365 stripping the content_type from cached responses.
3368 *) apachectl passes through any httpd options. Note: apachectl

3601 Added the APLOG_TOCLIENT flag to ap_log_rerror() to
3602 explicitly tell the server that warning messages should be sent
3603 to the client in addition to being recorded in the error log.
3604 Prior to this change, ap_log_rerror() always sent warning
3605 messages to the client. In one case, a faulty CGI script caused
3606 the server to send a warning message to the client that contained
3607 the full path to the CGI script. This could be considered a
3608 minor security exposure. [Bill Stoddard]
3610 *) mod_autoindex output when SuppressRules was specified would

3624 *) Change instdso.sh to use libtool --install everywhere and then
3625 clean up some stray files and symlinks that libtool leaves around
3626 on some platforms. This gets subversion building properly since
3627 it needed a re-link to be performed by libtool at install time,

3737 -DNO_DETACH except that it doesn't switch session ids).
3740 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
3741 for those platforms that support it. If using the default
3742 implementation, this is between pthread and sysvsem in priority.

3831 *) Added exp_foo and rel_foo variables to config_vars.mk for
3832 all Apache and Autoconf path variables (like --sysconfdir,
3833 --sbindir, etc). exp_foo is the "expanded" version, which means
3834 that all internal variable references have been interpolated.

3928 should it be necessary, the remote server socket is closed before
3929 transmitting the last buffer (set by ProxyIOBufferSize) to the

3948 sure that we aren't cd'ing to their home directory first. PR: 9993
3949 [Aaron Bannert, James LewisMoss <dres lewismoss.net>]
3951 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
3952 [Dirk-Jan Faber <dirk-jan selwerd.nl>, Aaron Bannert,
3953 Thom May <thom planetarytramp.net>]
3955 *) Rename the filter ordering priorities. The recent filtering fixes
3956 have showcased problems with their usage. Therefore, we need to
3957 rename them to increase the clarity. (CONTENT->RESOURCE,
3958 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
3960 Changes with Apache 2.0.33
3962 *) Fix a problem in the new --enable-layout functionality where
3963 it wouldn't allow overrides from variables like --prefix,
3964 --bindir, etc. [Thom May <thom planetarytramp.net>]
3966 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
3967 no longer hangs around waiting for the socket to close before
3968 returning exhaustive data. [Aaron Bannert]
3970 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
3971 [Thom May <thom planetarytramp.net>]
3973 *) Change mod_ssl to always do a full startup/teardown on restarts.
3974 this allows mod_ssl to be added to a server that is already
3975 running and makes it possible to add/change certs/keys after the
3976 server has been started. [Doug MacEachern]
3978 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
3979 This pipe must be a bidirectional 'console' style relay, which
3980 mod_ssl prints all prompts to the pipe's stdin, and reads the
3981 passphrases from the pipe's stdout. [William Rowe]
3983 *) Fix bug where --sysconfdir and --localstatedir were being
3984 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
3987 *) Fix --enable-layout to work again. Caution: When specifying
3988 --enable-layout, common arguments like --prefix, --exec-prefix,
3989 etc. will be ignored and the settings from the layout will be
3990 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]
3993 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
3994 regex pattern matching for the determination of which requests
3995 to use the remote proxy for. [Jim Jagielski]
3997 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
3999 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
4000 cruft in piped logs and rewritemap child processes.
4003 *) All instances of apr_lock_t have been removed and converted
4004 to one of the following new lock APIs: apr_thread_mutex.h,
4005 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
4006 use the apr_lock.h API, as the old API will soon be deprecated.
4009 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
4010 [Ralf S. Engelschall, Cliff Woolley]
4012 *) mod-include: make it handle flush'es and fix the 'false-alarm'
4013 [Justin Erenkrantz, Brian Pane, Ian Holsman]
4015 *) ap_get_*_filter_handle() functions to allow 3rd party modules
4016 to lookup filter handles so they can bypass the filter name
4017 lookup when adding filters to a request (via ap_add_*_filter_handle())
4018 [Ryan Morgan <rmorgan covalent.net>]
4020 *) Fix for multiple file buckets on Win32, where the first file
4021 bucket would cause the immediate closure of the socket on any
4022 non-keepalive requests. [Ryan Morgan <rmorgan covalent.net>]
4024 *) Correct Win32 failure of mmap of a segment beyond start of the
4025 file; fixes large SSL and similar transfers. [William Rowe]
4028 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
4029 multi-process mode to not "daemonize" while detaching from the
4030 controlling terminal. This is necessary for Apache to work with
4031 process-management tools like AIX's "System Resource Controller"
4032 as well as Dan Bernstein's "daemontools".
4033 [Jos Backus <josb cncdsl.com>, Aaron Bannert]
4035 *) Convert mod_auth_digest to use the new apr_global_mutex_t
4036 type. [Aaron Bannert]
4038 *) fix bug in mod-include where it wouldn't send a unmatched
4039 part if it was at the end of a bucket [Ian Holsman]
4041 *) worker MPM: Improve logging of errors with the interface between
4042 the listener thread and worker threads. [Jeff Trawick]
4044 *) Some browsers ignore cookies that have been merged into a
4045 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
4046 are now unmerged in the http proxy before being sent to the
4047 client. [Graham Leggett]
4049 *) Fix a problem with proxy where each entry of a duplicated
4050 header such as Set-Cookie would overwrite and obliterate the
4051 previous value of the header, resulting in multiple header
4052 values (like cookies) going missing.
4053 [Graham Leggett, Joshua Slive]
4055 *) Add the server-limit and thread-limit values to the scoreboard
4056 for the sake of third-party applications.
4057 [Adam Sussman <myddryn vishnu.vidya.com>]
4059 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
4061 *) OS/390: Get make install to properly copy DSO modules.
4064 *) Win32: Fix bug in mod_status with displaying "Restart Time"
4065 and "Server uptime".
4068 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
4070 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
4072 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
4073 [David MacKenzie <djm pix.net>]
4075 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
4076 [David MacKenzie <djm pix.net>]
4078 *) Fix segfault and display error when SSLMutex file can not be
4079 created. [Adam Sussman <myddryn vishnu.vidya.com>]
4081 *) Add reference counting to mod_mem_cache cache objects to
4082 better manage removing objects from the cache.
4085 *) Change the verbage on the ScoreBoardFile in our default configs.
4086 Also change the default to be commented out (unspecified) so we
4087 get anonymous shared memory by default. [Aaron Bannert]
4089 *) Implement new ScoreBoardFile directive logic. This affects how
4090 we create the scoreboard's shared memory segment. If the directive
4091 is present, a name-based segment is created. If the directive is
4092 not present, first an anonymous segment is created, and if that
4093 fails, a name-based segment is created from a file of the name
4094 DEFAULT_SCOREBOARD. This gives third-party applications the
4095 ability to access our scoreboard. [Aaron Bannert]
4097 *) Allow mod_deflate to work with non-GET requests and properly send
4098 Content-Lengths. [Sander Striker <striker apache.org>]
4100 *) Fix ap_directory_merge() to correctly merge configs when there is
4101 no <Directory /> block. [Justin Erenkrantz, William Rowe]
4103 *) Remove spurious debug messsages that are normal under HTTP
4104 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
4106 *) Fix a bug in mod_cgid that would prevent proper shutdown death
4107 of the cgid process. [Aaron Bannert]
4109 *) Add signal handling back in to the worker MPM for the one_process
4110 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
4112 *) Performance: Reuse per-connection transaction pools in the
4113 worker MPM, rather than destroying and recreating them. [Brian Pane]
4115 *) Remove all signals from the worker MPM's child process. Instead,
4116 the parent uses the Pipe of Death for all communication with the
4117 child processes. [Ryan Bloom]
4119 Changes with Apache 2.0.32
4121 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
4122 default if the directive is not specified. This mirrors older
4123 behavior without changes to the httpd.conf. [William Rowe]
4125 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
4126 the service, mpm and logging code, and bugs in apr_file_open_stderr
4127 and apr_file_dup2 functions. Win2K/XP services have no handles
4128 associated for stdin/out/err, which caused unpredictable behavior
4129 in the prior release. [William Rowe, Bill Stoddard]
4131 *) Win32: simplify the Application Event Log messages, since there isn't
4132 likely to be 'more information in the error log' before an error log
4133 has been opened. [William Rowe]
4135 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
4136 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
4138 *) Win32: apache -k shutdown now behaves like apache -k stop.
4141 *) Fix prefork to not kill the parent if a child hits a resource shortage
4142 on accept(). [Greg Ames]
4144 *) Fix seg faults that occur when what should be the httpd request line
4145 starts with \r\n followed by garbage. [Greg Ames]
4147 *) Allow statically linked support binaries with the new
4148 --enable-static-support flag, and enable this behavior in
4149 the binbuild script. Also add a new --enable-static-htdbm
4150 flag. [Aaron Bannert]
4152 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
4153 do only one stat() call when generating the directory listings.
4156 *) Fix resolve_symlink to save the original symlink name if known.
4159 *) Be a bit more sane with regard to CanonicalNames. If the user has
4160 specified they want to use the CanonicalName, but they have not
4161 configured a port with the ServerName, then use the same port that
4162 the original request used. [Ryan Bloom and Ken Coar]
4164 *) In core_input_filter, check for an empty brigade after
4165 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
4166 client says it will post some data but we get FIN before any
4167 data arrives. [Jeff Trawick]
4169 *) Not being able to bind to the socket is a fatal error. We should
4170 print an error to the console, and return a non-zero status code.
4171 With these changes, all of the Unix MPMs do that correctly.
4174 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
4175 through to CGI scripts. PR 9163
4176 [Brian Reid <breid customlogic.com>,
4177 Zvi Har'El <rl math.technion.ac.il>]
4179 *) binbuild.sh: Make sure that we use the expat from our source
4180 tree so that there aren't any surprises on the target machine.
4183 *) mod_cgid: Add retry logic for when the daemon can't fork fast
4184 enough to keep up with new requests. Start using
4185 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
4186 when we can't talk to the daemon. [Jeff Trawick]
4188 *) apxs: LTFLAGS envvar can override default libtool options. Try
4189 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
4190 the covers. [Jeff Trawick]
4192 *) The Location: response header field, used for external
4193 redirect, *must* be an absoluteURI. The Redirect directive
4194 tested for that, but RedirectMatch didn't -- it would allow
4195 almost anything through. Now it will try to turn an abs_path
4196 into an absoluteURI, but it will correctly varf like Redirect
4197 if the final redirection target isn't an absoluteURI. [Ken Coar]
4199 Changes with Apache 2.0.31
4201 *) Create the scoreboard (in the parent) in a global pool context,
4202 so it survives graceful restarts. This fixes a SEGV during
4203 graceful restarts. [Aaron Bannert]
4205 *) Add a timeout option to the proxy code 'ProxyTimeout'
4208 *) FTP directory listings are now always retrieved in ASCII mode.
4209 The FTP proxy properly escapes URI's and HTML in the generated
4210 listing, and escapes the path components when talking to the FTP
4211 server. It is now possible to browse the root directory by using
4212 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
4213 Also, the last path component may contain wildcard characters
4214 '*' and '?', and if they do, a directory listing is created instead
4215 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
4218 *) Added single-listener unserialized accept support to the
4219 worker MPM [Brian Pane]
4221 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
4222 the incoming host header through to the proxied server
4223 [Geoff <g.russell ieee.org>]
4225 *) New Directive Option for ProxyPass. It now can block a location
4226 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
4228 *) Don't let the default handler try to serve a raw directory. At
4229 best you get gibberish. Much worse things can happen depending
4230 on the OS. [Jeff Trawick]
4232 *) Change the pre_config hook to return a value. Modules can now emit
4233 an error message and then cause the server to quit gracefully during
4234 startup. This required a bump to the MMN. [Aaron Bannert]
4236 *) Fix some unix socket descriptor leaks in the handler side of
4237 mod_cgid (the part that runs in the server process). Whack a
4238 silly "close(-1)" in the handler too. [Jeff Trawick]
4240 *) Change the pre_mpm hook to return a value, so that scoreboard
4241 init errors percolate up to code that knows how to exit
4242 cleanly. This required a bump to the MMN. [Jeff Trawick]
4244 *) Add the socket back to the conn_rec and remove the create_connection
4245 hook. The create_connection hook had a design flaw that did not
4246 allow creating connections based on vhost info. [Bill Stoddard]
4248 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
4249 Resolves the common case of using negotation to resolve the request
4250 /script/foo for /script.cgi/foo. [William Rowe]
4252 *) Added new functions ap_add_(input|output)_filter_handle to
4253 allow modules to bypass the usual filter name lookup when
4254 adding hard-coded filters to a request [Brian Pane]
4256 *) caching should now work on subrequests (still very experimental)
4259 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
4261 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
4264 *) Refactor ap_rgetline so that it does not use an internal brigade.
4265 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
4267 *) Remove mod_auth_db. [Justin Erenkrantz]
4269 *) Do not install unnecessary pcre headers like config.h and internal.h.
4270 [Joe Orton <joe manyfish.co.uk>]
4272 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
4273 (as it does for a normal request). quick_handled sub-requests now work
4274 in mod-include [Ian Holsman]
4276 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
4277 'CONTENT' one, as it needs to run AFTER all content headers
4279 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
4282 *) Split out blocking from the mode in the input filters.
4285 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
4287 *) Cause Win32 to capture all child-worker process errors in
4288 Apache to the main server error log, until the child can
4289 open its own error logs. [William Rowe]
4291 *) HPUX 11.*: Do not kill the child process when accept()
4292 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
4293 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
4295 *) Fix a problem in the parsing of the <Proxy foo> directive.
4298 *) rewrite of mod_ssl input filter for better performance and less
4299 memory usage [Doug MacEachern]
4301 *) allow quick_handler to be run on subrequests. [Ian Holsman]
4303 *) mod_dav now asks its provider to place content directly into the
4304 filter stack when handling a GET request. The mod_dav/provider
4305 API has changed, so providers need to be updated. [Greg Stein]
4307 *) Clear the output socket descriptor in unixd_accept() to make sure
4308 we don't supply a bogus socket to the caller if the accept fails.
4309 This caused problems with the worker MPM, which tried to process
4310 the returned socket if it was non-NULL. [Brian Pane]
4312 *) Move a check for an empty brigade to the start of core input filter
4313 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
4315 *) Add FileETag directive to allow configurable control of what
4316 data are used to form ETag values for file-based URIs. MMN
4317 bumped to 20020111 because of fields added to the end of
4318 the core_dir_config structure. [Ken Coar]
4320 *) Fix a segfault in mod_rewrite's logging code caused by passing the
4321 wrong config to ap_get_remote_host(). [Jeff Trawick]
4323 *) Allow mod_cgid to work from a binary distribution install by
4324 using 755 for the permissions on the log directory instead of
4327 *) Fixed a segfault that happened during graceful shutdown (or when
4328 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
4330 *) Split all Win32 modules [excluding the core components mod_core,
4331 mod_so, mod_win32 and the winnt mpm] into individual loadable
4332 modules, so the administrator may individually disable the former
4333 compiled-in modules by simply commenting out their LoadModule
4334 directives. [William Rowe]
4336 *) Saved Win32 module authors and porters many future headaches, by
4337 duplicating the appropriate .h files such as os.h into the include
4338 directory, including in the build tree. [William Rowe]
4340 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
4341 Use SSL functions/macros instead of directly dereferencing SSL
4342 structures wherever possible.
4343 Add type-casts for the cases where functions return a generic pointer.
4344 Add $SSL/include to configure search path.
4345 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
4347 *) Moved several pointers out of the shared Scoreboard so it is
4348 more portable, and will present the vhost name across server
4349 generation restarts. [William Rowe]
4351 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
4354 Changes with Apache 2.0.30
4356 *) Fix the main bug for FreeBSD and threaded MPM's. There are
4357 still issues (see STATUS) but at least the server will now
4358 run without crashing the machine.
4359 [David Reid, Aaron Bannert, Justin Erenkrantz]
4361 *) Fix a typo in mod_deflate's m4 config section.
4362 [albert chin <china thewrittenword.com>]
4364 *) Fix a couple of mod_proxy problems forwarding HTTP connections
4365 and handling CONNECT:
4366 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
4367 (2) Proxy failed to connect when the first IP address returned by
4368 the resolver was unreachable but a secondary IP address was.
4371 *) Fix the module identifer as shown in the docs for various core
4372 modules (e.g., the identifer for mod_log_config was previously
4373 listed as config_log_module). PR #9338
4374 [James Watson <ap2bug sowega.org>]
4376 *) Fix LimitRequestBody directive by placing it in the HTTP
4377 filter. [Justin Erenkrantz]
4379 *) Fix mod_proxy seg fault when the proxied server returns
4380 an HTTP/0.9 response or a bogus status line.
4383 *) Prevent mod_proxy from truncating one character off the
4384 end of the status line returned from the proxied server.
4385 [Adam Sussman, Bill Stoddard]
4387 *) Eliminate loop in ap_proxy_string_read().
4388 [Adam Sussman, Bill Stoddard]
4390 *) Provide $0..$9 results from mod_include regex parsing.
4393 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
4395 *) Introduced the ForceLanguagePriority directive, to prevent
4396 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
4397 when using Multiviews. [William Rowe]
4399 *) Fix a problem which prevented mod_cgid and suexec from working
4400 together reliably [Greg Ames]
4402 *) Remove the call to exit() from within mod_auth_digest's post_config
4403 phase. [Aaron Bannert]
4405 *) Fix a problem in mod_auth_digest that could potentially cause
4406 problems with initialized static data on a system that uses DSOs.
4409 *) Fix a segfault in the worker MPM that could happen during
4410 child process exits. [Brian Pane, Aaron Bannert]
4412 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
4414 *) Fix matching of vhosts by ip address so we find IPv4
4415 vhost address when target address is v4-mapped form of
4416 that address. [Jeff Trawick]
4418 *) More performance tweaks to the BNDM string-search algorithm
4419 used to find "<!--#" tokens in mod_include [Brian Pane]
4421 *) Miscellaneous small performance fixes: optimized away various
4422 string copy operations and removed large temp buffers from
4423 the stack [Brian Pane]
4425 *) Fixed startup segfault that occurred when a VirtualHost
4426 directive had a port but no address [Brian Pane]
4428 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
4430 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
4431 if oslevel < WINNT. This should fix several problems reported
4432 Against 2.0.28 on Windows 98 [Bill Stoddard]
4434 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
4435 to fail. [Bill Stoddard]
4437 *) Change core code to allow an MPM to set hard thread/server
4438 limits at startup. prefork, worker, and perchild MPMs now have
4439 directives to set these limits. [Jeff Trawick]
4441 *) Win32: The async AcceptEx() event should be autoreset upon
4442 successful completion of a wait (WaitForSingleObject). This
4443 eliminates a number of spurious
4444 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
4447 *) Move any load library path environment variables out of
4448 apachectl and into a separate environment variable file which
4449 can be more easily tailored by the admin. The environment
4450 variable file as built by Apache may have additional system-
4451 specific settings. For example, on OS/390 we tailor the heap
4452 settings to allow lots of threads. [Jeff Trawick]
4454 *) Use the new APR pool code to reduce pool-related lock
4455 contention in the worker MPM. [Sander Striker]
4457 *) The POD no longer assumes the child is listening on 127.0.0.1
4458 and now pulls the first hostname in the list of listeners to
4459 perform the dummy connect on. This fixes a bug when the user
4460 had configured the Listen directive for an IP other than
4461 127.0.0.1. This would result in undead children and error
4462 messages such as "Connection refused: connect to listener".
4465 *) The worker MPM now respects the LockFile setting, needed to
4466 avoid locking problems with NFS. [Jeff Trawick]
4468 *) Fix segfault when worker MPM receives SIGHUP.
4469 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
4471 *) Fix bug that could potentially prevent the perchild MPM from
4472 working with more than one vhost/uid. [Aaron Bannert]
4474 *) Change make install and apxs -i processing of DSO modules to
4475 perform special handling on platforms where libtool doesn't install
4476 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
4477 which prevented standard LoadModule statements from working.
4480 *) Whenever mod_so is enabled (not just when there are DSOs for
4481 our modules), do whatever special magic is required for compiling/
4482 loading third-party modules. This allows third-party DSOs to
4483 be used on an AIX build when there were no built-in modules
4484 built as DSOs. (This should help on OS/390 and BeOS as well.)
4487 *) Allow apxs to be used to build DSOs on AIX without requiring the
4488 user to hard-code the list of import files. (This should help
4489 on OS/390 and BeOS as well.) [Jeff Trawick]
4491 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
4492 PR 8563, 8919 [William Rowe]
4494 *) Get binary builds working when libapr and libaprutil are built
4497 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
4498 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
4499 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
4501 *) Fix the handling of SSI directives in which the ">" of the
4502 terminating "-->" is the last byte in a file [Brian Pane]
4504 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
4505 message that we had back in apache-1.3 and still have scattered
4506 throughout our docs. [Aaron Bannert]
4508 *) Prevent the Win32 port from continuing after encountering an
4509 error in the command line args to apache. [William Rowe]
4511 *) On a error in the proxy, make it write a line to the error log
4514 *) Various mod_ssl performance improvements [Doug MacEachern]
4516 Changes with Apache 2.0.29
4518 *) Add buffering in core_output_filter to ensure that long
4519 lists of small buckets don't cause small packet writes.
4520 [Brian Pane, Ryan Bloom]
4522 *) Fix the installation target to make sure that the manual is
4523 installed in the correct location.
4524 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
4525 Gomez Henri <hgomez slib.fr>]
4527 *) Fix the cmd command for mod_include. When we are processing
4528 a cmd command, we do not want to use the r->filename to set
4529 the command name. The command comes from the SSI tag. To do this,
4530 I added a variable to the function that builds the command line
4531 in mod_cgi. This allows the include_cmd function to specify
4532 the command line itself. [Ryan Bloom]
4534 *) Change open_logs hook to return a value, allowing you
4535 to flag a error while opening logs
4536 [Ian Holsman, Doug MacEachern]
4538 *) Change post_config hook to return a value, allowing you
4539 to flag a error post config
4540 [Ian Holsman, Jeff Trawick]
4542 *) Allow SUEXEC_BIN (the path to the suexec binary that is
4543 hard-coded into the server) to be specified to the configure
4544 script by the --with-suexec-bin parameter. [Aaron Bannert]
4546 *) Fix segv in worker MPM following accept on pipe-of-death
4549 *) Add mod_deflate to experimental.
4550 [Ian Holsman, Justin Erenkrantz]
4552 *) Bail out at configure time if an invalid MPM was specified.
4553 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4555 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
4556 configured [John Sterling <sterling covalent.net>]
4558 *) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>]
4560 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
4562 *) Optimization for the BNDM string-search function in
4563 mod_include. [Brian Pane]
4565 *) Fixed the behavior of the XBitHack directive.
4566 [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
4568 *) The threaded MPM for Unix has been removed. Use the worker
4569 MPM instead. [various]
4571 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
4572 in logging the error from a failed DNS lookup. [Jeff Trawick]
4574 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
4577 *) Get mod_cgid killed when a MPM exits due to a fatal error.
4580 *) Fix a file descriptor leak in mod_include. When we include a
4581 file, we use a sub-request, but we didn't destroy the sub-request
4582 immediately, instead we waited until the original request was
4583 done. This patch closes the sub-request as soon as the data is
4584 done being generated. [Brian Pane <bpane pacbell.net>]
4586 *) Allow modules that add sockets to the ap_listeners list to
4587 define the function that should be used to accept on that
4588 socket. Each MPM can define their own function to use for
4589 the accept function with the MPM_ACCEPT_FUNC macro. This
4590 also abstracts out all of the Unix accept error handling
4591 logic, which has become out of synch across Unix MPMs.
4594 *) Fix a bug which would cause the response headers to be omitted
4595 when sending a negotiated ErrorDocument because the required
4596 filters were attached to the wrong request_rec.
4597 [John Sterling <sterling covalent.net>]
4599 *) Remove commas from the end of the macros that define
4600 directives that are used by MPMs. Prior to this patch,
4601 you would use these macros without commas, which was unlike
4602 the macros for any other directives. Now, the caller provides
4603 the comma rather than the macro providing it. This makes
4604 the macros look more like the rest of the directives.
4605 [Ryan Bloom and Cliff Woolley]
4607 *) Add 'redirect-carefully' environment option to disable sending
4608 redirects under special circumstances. This is helpful for
4609 Microsoft's WebFolders when accessing a directory resource via
4610 DAV methods. [Justin Erenkrantz]
4612 *) Begin to abstract out the underlying transport layer.
4613 The first step is to remove the socket from the conn_rec,
4614 the server now lives in a context that is passed to the
4615 core's input and output filters. This forces us to be very
4616 careful when adding calls that use the socket directly,
4617 because the socket isn't available in most locations.
4620 *) Really reset the MaxClients value in worker and threaded
4621 when the configured value is not a multiple of the number
4622 of threads per child. We said we did previously but we
4623 forgot to. [Jeff Trawick]
4625 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
4627 *) If shared modules are requested and mod_so is not available,
4628 produce a fatal config-time error. [Justin Erenkrantz]
4630 *) Improve http2env's performance by cutting the work it has to
4631 do. [Brian Pane <bpane pacbell.net>]
4633 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
4634 [Brian Pane <bpane pacbell.net>]
4636 Changes with Apache 2.0.28
4638 *) Fix infinite loop in mod_cgid.c.
4639 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
4641 *) When no port is given in a "ServerName host" directive, the
4642 server_rec->port is now set to zero, not 80. That allows for
4643 run-time deduction of the correct server port (depending on
4644 SSL/plain, and depending also on the current setting of
4645 UseCanonicalName). This change makes redirections
4646 work, even with https:// connections. As in Apache-1.3, the
4647 connection's actual port number is never used, only the ServerName
4648 setting or the client's Host: setting. Documentation updated
4649 to reflect the change. [Martin Kraemer]
4651 *) Add a '%{note-name}e' argument to mod-headers, which works in
4652 the same way as mod_log_confg. [Ian Holsman]
4654 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
4655 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
4656 MPMs. [Cliff Woolley]
4658 *) Introduce htdbm, a user management utility for db/dbm authorization
4659 databases. [Mladen Turk <mturk mappingsoft.com>]
4661 *) Optimize usage of strlen and strcat in ap_directory_walk.
4662 [Brian Pane <bpane pacbell.net>]
4664 Changes with Apache 2.0.27
4666 *) Introduce an Apache mod_ssl initial configuration template
4667 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
4669 *) Fixed a memory leak in the getline parsing code that could
4670 be triggered by arbitrarily large header lines. Requests
4671 from the core input filter for single lines are now limited
4672 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
4674 *) Fix a truncation bug in how we print the port on the Via: header.
4675 The routine that prints the Via: header now takes a length for
4676 the port string. [Zvi Har'El <rl math.technion.ac.il>]
4678 *) Some syntax errors in mod_mime_magic's magic file can result
4679 in a 500 error, which previously was unlogged. Now we log the
4680 error. [Jeff Trawick]
4682 *) Add the support/checkgid helper app, which checks the run-time
4683 validity of group identifiers usable in the Group directive.
4686 *) Various --enable-so options have been fixed: --enable-so is
4687 treated as "static"; explicit --enable-so=shared issues an error;
4688 and explicit --enable-so fails with error on systems without
4689 APR_HAS_DSO. [Aaron Bannert]
4691 *) Fix a segfault in the core input filter when the client socket
4692 gets disconnected unexpectedly. [Cliff Woolley]
4694 *) Fix the reporting for child processes that die. This removes
4695 all of the non-portable W* macros from Apache.
4696 [Jeff Trawick and Ryan Bloom]
4698 *) Win32: Track and display "Parent Server Generation:" in
4699 mod_status output. The generation will be bumped at
4700 server graceful restart, when the child process exits
4701 by hitting MaxRequestsPerChild or if the child
4702 process exits abnormally. [Bill Stoddard]
4704 *) Win32: Fix problem where MaxRequestsPerChild directive was
4705 not being picked up in favor of the default. Enable
4706 the parent to start up a new child process immediately upon
4707 the old child starting shutdown.
4710 *) Fix some bungling of the remote port in rfc1413.c so that
4711 IdentityCheck retrieves the proper user id instead of failing
4712 and thus always returning "nobody."
4713 [Dick Streefland <Dick.Streefland xs4all.nl>]
4715 *) Introduced thread saftey for mod_rewrite's internal cache.
4716 [Brian Pane <bpane pacbell.net>]
4718 *) Simplified mod_env's directives to behave as most directives are
4719 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
4720 directive following that UnsetEnv within the same container.
4721 Also provides a runtime startup warning if a PassEnv configured
4722 environment value is undefined. [William Rowe]
4724 *) The worker MPM is now completely ported to APR's new lock API. It
4725 uses native APR types for thread mutexes, cross-process mutexes,
4726 and condition variables. [Aaron Bannert]
4728 *) Sync up documentation to remove all references to the now deprecated
4729 Port directive. [Justin Erenkrantz]
4731 *) Moved all ldap modules from the core to httpd-ldap sub-project
4734 *) Exit when we can't listen on any of the configured ports. This
4735 is the same behavior as 1.3, and it avoids having the MPMs to
4736 deal with bogus ap_listen_rec structures. [Jeff Trawick]
4738 *) Cleanup the proxy code that creates a request to the origin
4739 server. This change adds an optional hook, which allows modules
4740 to gain control while the request is created if the proxy module
4741 is loaded. The purpose of this hook is to allow modules to add
4742 input and/or output filters to the request to the origin. While
4743 I was at it, I made the core use this hook, so that proxy request
4744 creation uses some of the code from the core. This can still be
4745 greatly improved, but this is a good start. [Ryan Bloom]
4747 Changes with Apache 2.0.26
4749 *) Port the MaxClients changes from the worker MPM to the threaded
4752 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
4753 with the new input filtering system. [Justin Erenkrantz]
4755 *) Introduce the MultiviewsMatch directive, to allow the operator
4756 to be flexible in recognizing Handlers and Filters filename
4757 extensions as part of the Multiviews matching logic, strict with
4758 MultiviewsMatch NegotiatedOnly to accept only filename extentions
4759 that designate negotiated parameters, (content type, charset, etc.)
4760 or MultiviewsAll for the 1.3 behavior of matching any files, even
4761 if they have unregistered extensions. [William Rowe]
4763 *) Fixed the configure script to add a LoadModule directive to
4764 the default httpd.conf for any module that was compiled
4765 as a DSO. [Aaron Bannert <aaron clove.org>]
4767 *) rewrite mod_ssl input filtering to work with the new input filtering
4768 system. [Justin Erenkrantz]
4770 *) prefork: Don't segfault when we are able to listen on some but
4771 not all of the configured ports. [Jeff Trawick]
4773 *) Build mod_so even if no core modules are built shared.
4774 [Aaron Bannert <aaron clove.org>]
4776 *) Introduce ap_directory_walk rewrite (with further optimizations
4777 required) to adapt to the ap_process_request_internal() changes.
4778 Optimized so subrequests and redirects now reuse previous section
4779 merges, until we mismatch with the original directory_walk, and
4780 precomputed r->finfo results will cause directory_walk to skip
4781 the most expensive phases of the function. [William Rowe]
4783 *) Allow ApacheMonitor to connect to and control Apache on other
4784 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
4786 *) Remove the Port directive. In it's place, the Listen directive
4787 is now a required directive, which tells Apache what port to
4788 listen on. The ServerName directive has also been extended
4789 to accept an optional port. If the port is specified to the
4790 ServerName, the server will report that port whenever it
4791 reports the port that it is listening on. This change was
4792 made to ease configuration errors that stem from having a Port
4793 directive, and a Listen directive. In that situation, the server
4794 would only listen to the port specified by the Listen command,
4795 which caused a lot of confusion to users. [Ryan Bloom]
4797 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
4798 build, as loadable modules. [William Rowe]
4800 *) Fix --enable-mods-shared processing. If most is specified,
4801 then all modules that can be compiled as shared modules are.
4802 [Aaron Bannert <aaron clove.org>]
4804 *) Update the mime.types file to map video/vnd.mpegurl to mxu
4805 and add commonly used audio/x-mpegurl for m3u extensions.
4806 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
4808 *) Eliminate the depreciated r->content_language, in favor of the array
4809 r->content_languages introduced many years ago. Module authors must
4810 substantially overhaul their modules, so this needs to be upgraded
4811 if the module still relied on backwards-brokeness. [William Rowe]
4813 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
4816 *) Rewrite the input filtering mechanisms to consolidate and reorganize
4817 code. In short, core_input_filter does something now and
4818 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
4820 *) Update the Win32 build to re-absorb mod_proxy and family.
4823 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
4824 current SDK.) [William Rowe]
4826 *) Some style changes to the code that does ProxyErrorOverride. Fixed
4827 config merge behaviour. [Graham Leggett]
4829 *) Allow support programs to be compiled against a static version
4830 of libapr. This allows the smaller support programs to be
4831 relocated. [Aaron Bannert <aaron clove.org>]
4833 *) Update the mime.types file to the registered media types as
4834 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
4836 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
4837 number of clients that can connect at the same time, instead of
4838 specifying the maximum number of child processes.
4839 [Aaron Bannert <aaron clove.org>]
4841 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
4842 be consistent with 1.3. [Justin Erenkrantz]
4844 *) Cache apr_explode_localtime() value for 15 seconds.
4845 [Brian Pane <bpane pacbell.net>]
4847 *) Fix mod_include to not return ETag or Last-Modified headers.
4848 [Ian Holsman <ianh cnet.com>]
4850 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
4852 *) Eliminate the wasteful run-time conversion of method names from strings
4853 to numbers in places where the methods are known at compile time.
4854 [Brian Pane <bpane pacbell.net>]
4856 *) Turn the worker MPM's queue into a LIFO. This may
4857 improve cache-hit performance under some conditions.
4858 [Aaron Bannert <aaron clove.org>]
4860 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
4861 support it. [Justin Erenkrantz]
4863 *) Cleanup the worker MPM. We no longer re-use transaction
4864 pools. This incurs less overhead than shuffling the pools
4865 around so that they can be re-used. Remove one of the
4866 queue's condition variables. We just redefined the API to
4867 state that you can't try to add more stuff than you allocated
4868 segments for. [Aaron Bannert <aaron clove.org>]
4870 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
4872 *) Fixed persistent connections when a request contains a body.
4875 *) mod_dav uses a new API to speak to the backend provider for dead
4876 property management. [Greg Stein]
4878 *) Remove the Win32 script-processing exception from mod_cgi, and
4879 roll build_command_line/build_argv_list into a unified, overrideable
4880 ap_cgi_build_command optional function. [William Rowe]
4882 *) Rewrite find_start_sequence to use a better search algorithm
4883 to find the start tag. [Justin Erenkrantz]
4885 *) Fix a seg fault in mod_include. When we are generating an
4886 internal redirect, we must set r->uri to "", not a bogus
4887 string, and not NULL. [Ryan Bloom]
4889 *) Optimized location_walk, so subrequests, redirects and second passes
4890 now reuse previous section merges on a <Location > by <Location >
4891 basis, until we mismatch with the original location_walk.
4894 *) Back out the 1.45 change to util_script.c. This change made
4895 us set the environment variable REQUEST_URI to the redirected
4896 URI, instead of the originally requested URI.
4897 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4899 *) Make mod_include do lazy evaluation of potentially expensive to
4900 compute variables. [Brian Pane <bpane pacbell.net>]
4902 *) Fix logging of bytes sent for HEAD requests. %b and %B should
4903 log either - or 0, before this patch, they were both logging
4904 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
4906 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
4907 than per character. [Brian Pane <bpane pacbell.net>]
4909 *) Normalize the primary request, redirects and sub-requests to
4910 run the same ap_process_request_internal for consistency in
4911 robustness, behavior and security. [William Rowe]
4913 *) Fix a segfault with mod_include when r->path_info is not set
4914 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
4916 *) Add -X functionality back. This indicates to all MPMs and any other
4917 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
4919 *) Some initial support for the cygwin platform [prefork only].
4920 This is not to be confused with support for the WinNT/Win32
4921 platform, which is the recommended configuration for native
4922 Win32 users. The cygwin platform support is recommended for
4923 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
4925 *) Changed syntax of Set{Input|Output}Filter. The list of filters
4926 must be semicolon delimited (if more than one filter is given.)
4927 The Set{Input|Output}Filter directive now overrides a parent
4928 container's directive (e.g. SetInputFilter in <Directory /web/foo>
4929 will override any SetInputFilter directive in <Directory /web>.)
4930 This new syntax is more consistent with Add{Input|Output}Filter
4931 directives defined in mod_mime. Also cures a bug in prior releases
4932 where the Set{Input|Output}Filter directive would corrupt the
4933 global configuration if the multiple directives were nested.
4936 *) Cured what's ailed mime for quite some time. If an AddSomething
4937 was given in the configuration (Language, Charset, Handler or
4938 Encoding) Apache would set the content type as given by AddType,
4939 but refused to check the mime.types file if AddType wasn't given
4940 for that specific extension. Setting the AddHandler for .html
4941 without setting the AddType text/html html would cause Apache to
4942 use the default content type. [William Rowe]
4944 *) Added some bulletproofing to memory allocation in the LDAP cache
4945 code. [Graham Leggett]
4947 Changes with Apache 2.0.25
4949 *) Move the installed /manual directory out of the /htdocs/ tree, so
4950 that it can be kept more independently from the remaining document
4951 root. The "Alias /manual ..." already allowed for easy projection
4952 into existing private document trees. [Martin Kraemer]
4954 *) Add specified user attributes to the environment when using
4955 mod_auth_ldap. This allows you to use mod_include to embed specified
4956 user attributes in a page like so:
4957 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
4960 *) Fix a performance problem with the worker MPM. We now create
4961 transaction pools once, and re-use them for each connection.
4962 [Aaron Bannert <aaron clove.org>]
4964 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
4965 of a 'handler' or 'filter', so that any filename extension that does
4966 not contribute to the negotiated metadata can't be served without
4967 an explicit request. E.g., if the .Z extension is associated with
4968 an unzip filter, the user request somefile.Z.html, mod_negotiation
4969 won't serve it. It can serve somefile.Z.html when somefile.Z is
4970 requested, since the .Z extension is explictly requested, if the
4971 .html extension is associated with ContentType text/html.
4974 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
4975 and corresponding AddOutputFilter syntax, to insert one or more
4976 filters by mod_mime filename extension processing.
4979 *) Fix a growing connection pool in core_output_filter() for
4980 keepalive requests. [Jeff Trawick]
4982 *) Moved split_and_pass_pretag_buckets back to being a
4983 macro at Ryans's request. Removed the return from it
4984 by setting and returning a return code instead. Updated
4985 the code to check the return code from the macro and
4986 do the right thing. [Paul J. Reder]
4988 *) Fix a segfault when a numeric value was received for Host:.
4991 *) Add a function ap_remove_input_filter. This is to match
4992 up with ap_remove_output_filter. [Ryan Bloom]
4994 *) Clean up location_walk, so that this step performs a minimum
4995 amount of redundant effort (it must be run twice, but it will no
4996 longer reparse all <Location > blocks when the request uri
4997 hadn't changed.) [William Rowe]
4999 *) Eliminate proxy: (and all other 'special') processing from the
5000 ap_directory_walk() phase. Modules that want to use special
5001 walk logic should refer to the mod_proxy map_to_location example,
5002 with it's proxy_walk and proxysection implementation. This makes
5003 either directory_walk flavor much more legible, since that phase
5004 only runs against real <Directory > blocks.
5007 *) SECURITY: Fix a security problem in mod_include which would allow
5008 an SSI document to be passed to the client unparsed.
5009 [Cliff Woolley, Brian Pane]
5011 *) Introduce the map_to_storage hook, which allows modules to bypass
5012 the directory_walk and file_walk for non-file requests. TRACE
5013 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
5014 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
5017 *) Add the ability for mod_include to add the INCLUDES filter
5018 if the file is configured for the server-parsed handler.
5019 This makes the configuration for .shtml files much easier
5020 to understand, and allows mod_include to honor Apache 1.3
5021 config files. Based on Doug MacEachern's patch to PHP
5022 to do the same thing. [Ryan Bloom]
5024 *) force OpenSSL to ignore process local-caching and to always
5025 get/set/delete sessions using mod_ssl's callbacks
5026 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
5027 Geoff Thorpe <geoff geoffthorpe.net>]
5029 *) Make the worker MPM shutdown and restart cleanly. This also
5030 cleans up some race conditions, and gets the worker using
5031 pools more cleanly. [Aaron Bannert <aaron clove.org>]
5033 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
5035 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
5037 *) Fix for mod_include. Ryan's patch to check error
5038 codes put a return in the wrong place. Also, the
5039 include handler return code wasn't being checked.
5040 I don't like macros with returns, so I converted
5041 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
5042 [Paul J. Reder <rederpj raleigh.ibm.com>]
5044 *) fix segv in mod_mime if no AddTypes are configured
5045 [John Sterling <sterling covalent.net>]
5047 *) Enable ssl client authentication at SSL_accept time
5048 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
5050 *) Fix a segfault in mod_include when the original request has no
5051 associated filename (e.g., we're filtering the error document for
5052 a bad URI). [Jeff Trawick]
5054 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
5056 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
5057 of httpd is started and shuts down due to socket conflict. Moving the
5058 call to ap_log_pid solves the problem.
5060 *) Changed the late-1.3 log_config substitution %c to %X, to log the
5061 status of the closed connection, as it conflicts with the far more
5062 common, historical ssl logging directive %...{var}c. [William Rowe]
5064 *) Added the common error/ tree to the build/install targets
5065 (similar to the common icons/ tree) for the multi-language error
5066 messages that Lars committed earlier. [William Rowe]
5068 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
5070 *) Added a default commented-out mod_ldap and mod_auth_ldap
5071 configuration to httpd-std.conf and httpd-win.conf
5074 *) Added documentation for mod_ldap and mod_auth_ldap.
5077 *) Enabled negative caching on attribute comparisons in the LDAP cache.
5078 Fixed a problem where the default cache TTL was set in milliseconds
5079 not microseconds causing the cache to time out almost immediately.
5082 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
5083 module code to follow APR. [Graham Leggett]
5085 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
5086 cleaned up when the connection pool pool is cleaned up.
5089 *) Fix a minor issue with Jeff Trawick's mod_include
5090 patch. Without this patch, the code will just allocate
5091 more bytes in get_combined_directive than are needed.
5094 *) Added the LDAP authentication module mod_auth_ldap.
5095 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
5097 *) Added the LDAP cache and connection pooling module mod_ldap.
5098 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
5100 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
5101 by allowing a module to disable itself if its prerequisites are not
5102 met. [Justin Erenkrantz]
5104 Changes with Apache 2.0.24
5106 *) Fix a couple of issues in mod_include when the tag appeared at
5107 offsets near 8192 in the file being parsed. [Jeff Trawick]
5109 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
5110 reached. [Jeff Trawick]
5112 *) Numerous improvements to the Win32 build system. Introduced command line
5113 builds without requiring .mak files for MSVC 6.0 and later versions.
5114 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
5117 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
5118 reporting of uninstalled services and other error conditions, and changed the
5119 default service name to Apache2. [William Rowe]
5121 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
5122 compatibility with existing Apache 1.3 Win32 Apache management utilites.
5123 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
5125 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
5126 [William Rowe, Greg Ames]
5128 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
5129 and RemoveCharset directives. [William Rowe]
5131 *) The Unix MPMs other than perchild now allow child server
5132 processes to use the accept mutex when starting as root and
5133 using SysV sems for the accept mutex. Previously, this
5134 combination would lead to fatal errors in the child server
5135 processes. perchild can't use SysV sems because of security
5136 issues. [Jeff Trawick, Greg Ames]
5138 *) Added Win32 revision stamp resources to all http binaries
5139 (including modules/ and support/ tools.) PR7322 [William Rowe]
5141 *) Fix ap_rvprintf to support more than 4K of data at one time.
5142 [Cody Sherr <csherr covalent.net>]
5144 *) We have always used the obsolete/deprecated Netscape syntax
5145 for our tracking cookies; now the CookieStyle directive
5146 allows the Webmaster to choose the Netscape, RFC2109, or
5147 RFC2965 format. The new CookieDomain directive allows the
5148 setting of the cookie's Domain= attribute, too. PR #s 5006,
5149 5023, 5920, 6140 [Ken Coar]
5151 *) Tweak server/Makefile so that the rules for generating exports.c
5152 are compatible with make utilities which don't expand wildcards
5153 in a dependency list (e.g., OS/390 make, certain levels of GNU
5154 make). [Jeff Trawick]
5156 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
5158 *) Begin to sanitize the MPM configuration directives. Now, all
5159 MPMs use the same functions for all common MPM directives. This
5160 should make it easier to catch all bugs in these directives once.
5161 [Cody Sherr <csherr covalent.net>]
5163 *) Close a major resource leak. Every time we had issued a
5164 graceful restart, we leaked a socket descriptor.
5167 *) Fix a problem with the new method code. We need to cast
5168 the 1 to an apr_int64_t or it will be treated as a 32-bit
5169 integer, and it will wrap after being shifted 32 times.
5170 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
5172 *) Fix a bug in mod_expires. Previous to this patch, if you
5173 told mod_expires to add 604800 seconds to the last-modified
5174 time, it actually added 604800 usec's to the last-modified time,
5175 so that when looking at the response it looked like nothing
5176 had been done. The root of the problem was that we always compute
5177 time in usec's, but we ask users to input sec's. This means we
5178 need to convert to usec's before using those values.
5181 *) The worker MPM now handles shutdown and restart requests. It
5182 definitely isn't perfect, but we do stop the servers correctly.
5183 The biggest problem right now is that SIGHUP causes the server to
5184 just die. [Ryan Bloom]
5186 Changes with Apache 2.0.23
5188 *) Use the prefork MPM by default on Unix. [various]
5190 *) Added a systray icon monitor application for Win32.
5191 [Mladen Turk <mturk mappingsoft.com>]
5193 *) mod_rewrite: Fix the line ending on some non-Unix systems for
5194 messages written to the rewrite log.
5195 [Richard Labennett <rlabenn us.ibm.com>]
5197 *) All mod_autoindex query parsing is now quietly quashed with the
5198 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
5199 still drops the column sort <a href>'s for the column headers, but
5200 IgnoreClient is required to ignore these Query options entirely.
5203 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
5204 to allow the client to select plain, FancyIndexing or HTMLTable
5205 formatting, V=[0|1] to inhibit or enable version sorting, and
5206 P=pattern to return only specific files. The old Query Arguments
5207 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
5208 as before), and O=A|D for ordering ascending or descending.
5211 *) Fixed an error in mod_include's directive parsing routines which
5212 caused #if, #elif, and #else expressions containing backslashes
5213 to be improperly evaluated. [Cliff Woolley]
5215 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
5216 drop the icon column, SuppressRules to drop the <hr> elements,
5217 and HTMLTable to create rudimentary HTML table listings (implies
5218 FancyIndexing). [William Rowe]
5220 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
5221 from Apache 1.3.15. This is needed for two reasons, first, given
5222 multiple machines within a server farm, ETags and Last-Modified
5223 stamps won't correspond from machine to machine, and second, many
5224 Unixes don't capture changes to the date or time stamp of existing
5225 files, since these don't modify the dirent itself. [William Rowe]
5227 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
5228 and DirectoryWidth options from Apache 1.3.10.
5229 [William Rowe, Ken Coar]
5231 *) Eliminated FancyIndexing directive, deprecated early in Apache
5232 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
5234 *) mod_autoindex now excludes any file names that would result in
5235 an error, other than a success or redirect. Also optimized
5236 the parent directory, always included except in the URI '/'.
5239 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
5240 negotiated index pages, and prevent the server from defaulting
5241 to an autoindex of the directory. mod_negotiation will now die
5242 with a 500 Internal Error if it could match some filenames
5243 (e.g. for mod_dir) but none can be served. mod_negotation now
5244 refuses to serve any file with an extention that mod_mime doesn't
5245 recognize, and wasn't part of the request. [William Rowe]
5247 *) Eliminate mod_cgi's handling of .exe files without the .exe file
5248 extension. This is already handled by multiviews, if the admin
5249 wishes to AddHandler .exe or define a content type handler and
5250 associate .exe files with that content type. Multiviews must be
5251 enabled to allow these to be served. [William Rowe]
5253 *) Speed up the server's response to a spike in incoming workload
5254 or restarts by assigning empty scoreboard slots to new processes
5255 when they are available. [Greg Ames]
5257 *) Add a handler to mod_includes.c. This handler is designed to
5258 implement the XbitHack directive. This can't be done with a
5259 fixup, because we need to check the content-type, which is
5260 only available in the handler phase. [Ryan Bloom]
5262 *) Make the includes filter check return codes from filters lower in
5263 the filter chain. If a lower level filter returns an error, then
5264 the request needs to stop immediately. This allows mod_include to
5265 stop parsing data once a lower filter recognizes an error.
5268 *) Add the ability to extend the methods that Apache understands
5269 and have those methods <limit>able in the httpd.conf. It uses
5270 the same bit mask/shifted offset as the original HTTP methods
5271 such as M_GET or M_POST, but expands the total bits from an int to
5272 an ap_int64_t to handle more bits for new request methods than
5273 an int provides. [Cody Sherr <csherr covalent.net>]
5275 *) Fix broken mod_mime behavior in merging its arguments. Possible
5276 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
5278 *) Solve many mod_ssl porting issues (too many to detail) with
5279 help from the whole team, but most notably [Ralf S. Engelschall,
5280 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
5281 Doug MacEachern, William Rowe, Cliff Woolley]
5283 *) More stall fixes for the threaded & worker mpm's.
5284 Make mod_status output more accurate. Don't
5285 count workers in processes which aren't actively
5286 serving requests. [Greg Ames]
5288 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
5290 *) Add a single listener/multiple worker MPM. This MPM is
5291 definately not fully correct, but it allows us to solve many
5292 of the problems that exist in the threaded MPM. This is a
5293 modified version of the threaded MPM. [Ryan Bloom]
5295 *) Improve content generation throughout Apache, providing closer
5296 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
5297 Transitional specifications. [William Rowe]
5299 Changes with Apache 2.0.22
5301 *) Fix a problem where the threaded MPM stalls after restarts or
5302 segfaults. Also prevent multiple active processes from using
5303 the same scoreboard slot. [Greg Ames]
5305 *) Apache/Win32 now fills in the service description with Apache's
5306 server version string, including loaded and advertised modules.
5309 *) Improved support for the Win32 build, to recover gracefully from
5310 missing apr or apr-util directories or the awk interpreter,
5311 create the proper cgi-bin examples, including a test-cgi.bat, and
5312 fix the perl shebang line for printenv.pl, when installing from
5313 the build environment. [William Rowe]
5315 *) Fix a segfault in threaded.c caused by passing uninitialized
5316 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
5318 *) Use new APR number conversion functions to reduce CPU consumption
5319 when setting the content length, and in mod_log_config.
5322 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
5323 where HEAD response headers were being repeated twice for
5324 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
5325 problem in the http_header filter was exposed by the recent rewrite
5326 of the content_length filter. [Taketo Kabe, Bill Stoddard]
5328 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
5329 restarts. A garbage pointer to a vhost's server_rec from the
5330 previous generation was being left around under certain
5331 conditions. [Greg Ames]
5333 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
5334 used to appear as '(none', without the closing paren.
5335 [Günter Knauf <eflash gmx.net>]
5337 *) Improve the exports generating awk script. In the past, we had
5338 work around problems in the awk script by avoiding some #if and
5339 #ifdefs. This has bitten us many times in generating the exports.c
5340 file. This improvement allows corrects the header file parsing.
5341 [Sander Striker <striker apache.org>]
5343 Changes with Apache 2.0.21
5345 *) Resolve the Win32 htpasswd bug, where a file that existed would be
5346 overwritten, regardless of the -c flag.
5347 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
5349 *) Introduce connection sub-pools into ab. Truncating the lifetime
5350 of these allocations means that ab no longer perpetually grows
5351 its working set, running out of memory on large request attempts.
5354 *) Make scoreboard creation a hook. This allows management
5355 modules to have access to the scoreboard at the time that it is
5356 created, and at every restart request.
5357 [Cody Sherr <csherr covalent.net>]
5359 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
5360 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
5361 daemon index actually used in the scoreboard. I also
5362 updated the pertinent calls. [Paul J. Reder]
5364 *) Win32: Prevent listening sockets from being inherited by
5365 the Apache child process, CGI scripts, rotatelog process
5366 etc. If the Apache child process segfaults, any processes
5367 that the child started are not reaped. Prior to this fix,
5368 these processes inherited the listening sockets which sometimes
5369 prevented the restarted Apache child process from accepting
5370 connections (ie, the server would hang).
5373 *) Provide vhost and request strings when ExtendedStatus is on.
5376 *) Fix some issues with the pod and prefork: check the pod *after*
5377 processing a connection so that a server processing a time-
5378 consuming request bails out as soon as practical; when the
5379 parent process wakes up a server process via connect(), use an
5380 APR timeout on the connect() so that we don't hang for a long
5381 time if there aren't server processes around to do accept().
5382 [Jeff Trawick, Greg Ames]
5384 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
5385 spends a lot of time in apr_table_get calls. Using the default
5386 httpd.conf, the tables for languages and charsets are somewhat
5387 large, so the time spent scanning them on each request is
5388 significant. Replacing the tables with hash tables provides
5389 a nice speedup. [Brian Pane <bpane pacbell.net>]
5391 *) Add two functions to allow modules to access random parts of the
5392 scoreboard. This allows modules compiled for one MPM to access the
5393 scoreboard, even if it the server was compiled for another MPM.
5394 [Harrie Hazewinkel <harrie covalent.net>]
5396 Changes with Apache 2.0.20
5398 *) Fix problem in content-length filter where the filter would
5399 buffer all the output from a CGI before sending any bytes
5400 down the filter stack to the network. This problem would cause
5401 significant memory consumption if the CGIs generated
5402 lots of bytes. [Bill Stoddard]
5404 *) Get non-blocking CGI pipe reads working with the bucket brigades.
5407 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
5410 *) Fix a bug in the threaded MPM that would cause it to kill off all
5411 workers immediately after starting if the number of workers started
5412 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
5414 Changes with Apache 2.0.19
5416 *) Fix problem with threaded MPM. The problem was that if each child
5417 process was busy serving a single long-lived request and the server
5418 was sent a graceful restart signal, the server would stop serving
5419 requests. This would happen because each child process would wait to
5420 die until the last thread was done, and the parent wouldn't spawn any
5421 new children until a process died. Now, the parent looks at the fact
5422 that the children are dying gracefully, and starts new children.
5423 Those new children only start enough threads to compliment the number
5424 of threads in the other child process that shares the same spot in
5425 the scoreboard. In this way, we make sure to never go over
5426 MaxClients. [Ryan Bloom]
5428 *) modified mod_negotiation and mod_autoindex to speed up by almost a
5429 factor of two on apr_dir_read()-enhanced platforms, such as Win32
5430 and OS2, by calling ap_sub_request_lookup_dirent() with the results
5431 already provided by apr_dir_read(). [William Rowe]
5433 *) mod_file_cache is now more robust to filtering and serves requests
5434 slightly more efficiently. [Cliff Woolley]
5436 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
5437 Module was calling ap_rwrite() followed by ap_rflush() but the
5438 served content was not being displayed in the browser. Inspection
5439 of the output stream revealed that the first data chunk was
5440 missing the trailing CRLF required by the RFC. [Bill Stoddard]
5442 *) apxs no longer generates ap_send_http_header() in the example handler
5444 *) Fix an ab problem which could cause a divide-by-zero exception
5445 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
5446 [Ian Holsman <ianh cnet.com>]
5448 *) Solve case-insensitive platforms' confusion about negotiated
5449 filenames, allowing files of differnt case to match in choosing
5450 the document to serve. [William Rowe]
5452 *) Fix brokenness when ThreadsPerChild is higher than the built-in
5453 limit. We left ap_threads_per_child at the higher value which
5454 led to segfaults when doing certain scoreboard operations.
5457 *) Fix seg faults and/or missing output from mod_include. The
5458 default_handler was using the subrequest pool for files and
5459 MMAPs, even though the associated APR structures typically
5460 live longer than the subrequest. [Greg Ames]
5462 *) Extend mod_setenvif to support specifying regular expressions
5463 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
5464 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
5465 will cause HAVE_TS to be set if any of the request headers begins
5466 with "TS" and has a value that begins with any character in the
5467 set [a-z]. [Bill Stoddard]
5469 *) httpd children now re-bind themselves to a random CPU on
5470 multiprocessor systems on AIX via bindprocessor() in 2.0.
5471 [Victor J. Orlikowski]
5473 *) Fix htdigest. It would go into a loop in getline when adding
5474 a second user. [Bill Stoddard]
5476 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
5478 *) Automatically generate httpd.exp for AIX.
5479 DSOs now work again on AIX in 2.0
5480 [Victor J. Orlikowski]
5482 *) Add a new request hook, error_log. This phase allows modules
5483 to act on the error log string _after_ it has been written
5484 to the error log. The goal for this hook is to allow monitoring
5485 modules to send the error string to the monitoring agent.
5488 *) Modify mod_echo to make it use filters for input and output.
5489 [Ryan Morgan <rmorgan covalent.net>]
5491 *) Extend mod_headers to support conditional driven Header
5492 add, append and set. Use SetEnvIf to set an envar and conditionally
5493 add/append/set headers based on this envar thusly:
5495 SetEnvIf TSMyHeader value HAVE_TSMyHeader
5496 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
5498 If the request contains header "TSMyHeader: value" then header
5499 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
5502 *) Extend mod_headers to support using format specifiers on Header
5503 add, append and set header values. Two format specifiers are supported:
5505 %t - reports, in UTC microseconds since the epoch, when the
5506 request was received.
5508 %D - reports the time, in microseconds, between when the request was
5509 received and the response sent.
5512 Header add MyHeader "This request served in %D microseconds. %t"
5514 results in a header being added to the response that looks like this:
5516 MyHeader: This request served in D=5438 microseconds. t=991424704447256
5520 *) Fix reset_filter(). We need to be careful how we remove filters.
5521 If we set r->output_filters to NULL, we also have to reset the
5522 connection's filters. [John Sterling]
5524 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
5526 *) Add a check to ap_die() to make sure the filter stack is sane and
5527 contains the correct basic filters when an error occurs. This fixes
5528 a problem where headers are not being sent on error. [John Sterling]
5530 *) New Header directive 'echo' option. "Header echo regex" will
5531 cause any headers received on the request that match regex to be
5532 echoed to (included in) the response headers.
5535 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
5536 This prevented the inclusion of apr_compat.h. PR #7773
5537 [Oleg Broytmann <phd phd.pp.ru>]
5539 *) Moved util_uri to the apr-util library. This required a bunch of
5540 apr_name changes for the uri utility functions. [Justin Erenkrantz]
5542 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
5543 insert_filter phase so that other filters are not bypassed by default.
5546 *) Reimplement mod_headers as an output filter. mod_headers can now
5547 add custom headers to inbound requests using the RequestHeader directive
5548 and to responses using the same old Header directive. [Graham Leggett]
5550 Changes with Apache 2.0.18
5552 *) Fix command-line processing so that if a bad argument is specified
5553 Apache will exit. [Jeff Trawick]
5555 *) Change the make targets and rules to be consistent in all of the
5556 Apache-owned source trees. [Roy Fielding]
5558 *) Fix processing of the TRACE method. Previously we passed bogus
5559 parms to form_header_field() and it overlaid some vhost structures,
5560 resulting in a segfault in check_hostalias().
5561 [Greg Ames, Jeff Trawick]
5563 *) Win32: Add support for reliable piped logs. If the logging process
5564 goes down, Apache will automatically restart it. This function has
5565 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
5568 *) Do not start piped log processes during the config file
5569 preflight. This change also circumvents a problem on
5570 Windows where the rotatelog processes created during preflight
5571 was not getting cleaned up properly.
5574 *) add "Request Phase Participation" info to mod_info
5577 *) Make first phase changes to the scoreboard data structures in
5578 preparation for the rewriting of the scoreboard per my posted
5579 design notes. [Paul J. Reder]
5581 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
5582 and apr-util, allow it to be overridden by the configure command-line
5583 (default="--silent") and introduce LT_LDFLAGS to replace what we were
5584 formerly abusing as LTFLAGS. [Roy Fielding]
5586 *) Clean up the reporting of incorrect closing container tags.
5587 [Barrie Slaymaker <barries slaysys.com>]
5589 *) Simplify the configure process by moving all libtool stuff to APR
5590 and moving hints.m4 inline. [Roy Fielding]
5592 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
5593 of functions used by mod_proxy for export in the DLL
5594 [Ian Holsman <IanH cnet.com>]
5596 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
5597 request body from its stdin but no reqest body is being written to
5598 the cgi. [Jeff Trawick]
5600 *) mod_log_config: %c connection status incorrectly logged
5601 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
5604 *) Get mod_cern_meta working under Windows
5607 *) Create Files, and thus MMAPs, out of the request pool, not the
5608 connection pool. This solves a small resource leak that had us
5609 not closing files until a connection was closed. In order to do
5610 this, at the end of the core_output_filter, we loop through the
5611 brigade and convert any data we have into a single HEAP bucket
5612 that we know will survive clearing the request_rec.
5613 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
5616 *) Completely revamp configure so that it preserves the standard make
5617 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
5618 the configure additions to EXTRA_* variables. Also, allow the user
5619 to specify NOTEST_* values for all of the above, which eliminates the
5620 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
5621 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
5622 avoid pointless duplications. Fix the order in which flags are given
5623 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
5624 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
5625 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
5626 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
5628 *) Get mod_tls to compile/work better on Windows. PR #7612
5629 [Bernhard Schrenk <b.schrenk improx.com>]
5631 *) Fix shutdown/restart hangs in the threaded MPM.
5632 [Jeff Trawick, Greg Ames, Ryan Bloom]
5634 *) Removed the keptalive boolean from conn_rec because it is now only
5635 used by a single routine and can be replaced by a local variable.
5636 [Greg Stein, Ryan Bloom, Roy Fielding]
5638 *) Patch prefork to put enough of the signal processing back in so that
5639 signals are all handled properly now. The previous patch fixed the
5640 deadlock race condition, but broke the user directed signal handling.
5641 This fixes it to work the way it did before my previous prefork patch
5642 (primarily, SIGTERM is now working).
5644 *) Change how input filters decide how much data is returned to the
5645 higher filter. We used to use a field in the conn_rec, with this
5646 change, we use an argument to ap_get_brigade to determine how much
5647 data is retrieved. [Ryan Bloom]
5649 *) Fix seg fault at start-up introduced by Ryan's change to enable
5650 modules to specify their own logging tags. mod_log_config
5651 registers an optional function, ap_register_log_handler().
5652 ap_register_log_handler() was being called by http_core before
5653 the directive hash table was created. This patch creates the
5654 directive hash table before ap_register_log_handler() is
5655 registered as an optional function.
5656 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
5658 *) Add ap_set_int_slot() function
5659 [John K. Sterling <sterling covalent.net>]
5661 *) Under certain circumstances, Apache did not supply the
5662 right response headers when requiring authentication.
5663 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
5664 (This is a port of the change that went into Apache 1.3.19.)
5666 *) Allow modules to specify their own logging tags. This basically
5667 allows a module to tell mod_log_config that when %x is encountered
5668 a specific function should be called. Currently, x can be any single
5669 character. It may be more useful to make this a string at some point.
5672 Changes with Apache 2.0.17
5674 *) If a higher-level filter handles the byterange aspects of a
5675 request, then the byterange filter should not try to redo the
5676 work. The most common case of this happening, is a byterange
5677 request going through the proxy, and the origin server handles
5678 the byterange request. The proxy should ignore it.
5679 [Graham Leggett <minfrin sharp.fm>]
5681 *) Changed the threaded mpm to have child_main join to each of the
5682 worker threads to make sure the kids are all gone before child_main
5683 exits after a signal (cleanup from perform_idle_server_maintenance).
5684 This is an extension of Ryans recent commit to make the child_main
5687 *) Add more options to the ap_mpm_query function. This also allows MPMs to
5688 report if their threads are dynamic or static. Finally, this also
5689 implements a new API, ap_show_mpm, which returns the MPM that was
5690 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
5692 *) Do not install the binaries from the support directory twice.
5693 [jun-ichiro hagino <itojun iijlab.net>]
5695 *) The ap_f* functions should flush data to the filter that is passed
5696 in, not the filter after the one passed in.
5697 [Ryan Morgan <rmorgan covalent.net>]
5699 *) Make ab work again by changing its native types to apr types and formats.
5700 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
5702 *) Move the byterange filter and all of the supporting functions back
5703 to the HTTP module. The byterange filter turned out to be very
5704 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
5706 *) Make clean, distclean, and extraclean consistently according to the
5707 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
5709 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
5710 This may have been causing problems stopping processes in the threaded
5713 *) Fix content-length in mod_negotiation to a long int representation.
5716 *) Remove BindAddress from the default config file.
5717 [<giles nemeton.com.au>]
5719 *) Allow module authors to add a module to their Apache build using
5720 --with-module, without re-running buildconf. The syntax is:
5721 --with-module=module_type:/path/to/module.c
5722 The configure script will copy the module.c file to
5723 modules/module_type, and it will be added to the relevant Makefiles.
5724 currently, this only works for static modules. [Ryan Bloom]
5726 *) Changes required to make prefork clean up idle children properly.
5727 There was a window during which a starting worker deadlocks when
5728 an idle cleanup arrives before it completes init. Apache then keeps
5729 trying to cleanup the same deadlocked worker forever (until higher
5730 pids come along, but it still will never reduce below the deadlocked
5731 pid). Thus the number of children would not reduce to the correct
5732 idle level. [Paul J. Reder]
5734 Changes with Apache 2.0.16
5736 *) Change the default installation directory to /usr/local/apache2,
5737 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
5739 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
5742 *) Get MaxRequestsPerChild working with the Windows MPM.
5745 *) Make generic hooks to work, with mod_generic_hook_import/export
5746 experimental modules. [Ben Laurie, Will Rowe]
5748 *) Fix segfaults for configuration file syntax errors such as
5749 "<Directory>" followed by "</Directory" and
5750 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
5752 *) Cleanup the --enable-layout option of configure. This makes
5753 us use a consistent location for the config.layout file, and it
5754 makes configure more portable.
5755 [jun-ichiro hagino <itojun iijlab.net>]
5757 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
5758 csv/gnuplot format, rudimentary ssl support and various other tweaks
5759 to make results more true to what is measured. The upshot of this it
5760 turns out that 'ab' has often underreported the true performance of
5761 apache. Often by a order of magnitude :-) See talk/paper of Sander
5762 Temme at April ApacheCon 2001 for details.
5763 [Dirk-Willem van Gulik]
5765 *) Clean up mod_cgid's temporary request pool. Besides fixing a
5766 storage leak this ensures that some unnecessary pipes are closed.
5769 *) Performance: Add quick_handler hook. This hook is called at the
5770 very beginning of the request processing before location_walk,
5771 translate_name, etc. This hook is useful for URI keyed content
5772 caches like Mike Abbott's Quick Shortcut Cache.
5775 *) top_module global variable renamed to ap_top_module [Perl]
5777 *) Move ap_set_last_modified to the core. This is a potentially
5778 controversial change, because this is kind of HTTP specific. However
5779 many protocols should be able to take advantage of this kind of
5780 information. I expect that headers will need one more layer of
5781 indirection for multi-protocol work, but this is a small step in
5782 the right direction. [Ryan Bloom]
5784 *) Enable mod_status by default. This matches what Apache 1.3 does.
5787 *) Add a ScriptSock directive to the default config file. This is
5788 only enabled when mod_cgid is used.
5789 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5791 Changes with Apache 2.0.15
5793 *) Untangled the buildconf script and eliminated the need for build's
5794 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
5795 libtool muck that is now under srclib/apr/build. [Roy Fielding]
5797 *) Win32: Don't accept more connections than we have worker threads
5801 *) Fix bug in the Unix threaded.c MPM that allowed child processes
5802 to fork() new child processes.
5805 *) SECURITY: Fix a major security problem with double-reverse lookup
5806 checking. Previously, a client connecting over IPv4 would not be
5807 matched properly when the server had an IPv6 listening socket.
5808 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
5810 *) Change the way the beos MPM handles polling to allow it to stop and
5811 restart. Problem was the sockets being polled were being reset by
5812 the select call, so once it had accepted a connection it was no
5813 longer listening on the UDP socket we use for shutdown instructions.
5814 APR needs to be altered, patch on it's way. [David Reid]
5816 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
5817 on error exit from ap_getline(). Some other code got upset because
5818 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
5820 *) Handle ap_discard_request_body() being called more than once.
5821 [Greg Ames, Jeff Trawick]
5823 *) Get rid of an inadvertent close of file descriptor 2 in
5824 mod_mime_magic. [Greg Ames, Jeff Trawick]
5826 *) Add a hook, create_request. This hook allows modules to modify
5827 a request while it is being created. This hook is called for all
5828 request_rec's, main request, sub request, and internal redirect.
5829 When this hook is called, the r->main, r->prev, r->next
5830 pointers have been set, so modules can determine what kind of
5831 request this is. [Ryan Bloom]
5833 *) Cleanup the build process a bit more. The Apache configure
5834 script no longer creates its own helper scripts, it just
5836 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
5838 *) Stop the forced downgrade of the connection to HTTP/1.0 for
5839 proxy requests. [Graham Leggett]
5841 *) Avoid using sscanf to determine the HTTP protocol number in
5842 the common case because sscanf is a performance hog. From
5843 Mike Abbot's Accelerating Apache patch number 6.
5844 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
5846 *) SECURITY: Fix a security exposure in mod_access. Previously when
5847 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
5848 were not evaluated properly (PR #7407). Also, add the ability to
5849 specify IPv6 address strings with optional prefix length on Allow
5850 and Deny. [Jeff Trawick]
5852 *) Enhance rotatelogs so that a UTC offset can be specified, and
5853 the logfile name can be formatted using strftime(3). (Brought
5854 forward from 1.3.) [Ken Coar]
5856 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
5857 DuplicateHandle on an IOCompletionPort (a practice which
5858 MS "discourages"). The new model does not rely on associating
5859 the completion port with the listening sockets, thus the
5860 completion port can be completely managed within the child
5861 process. A dedicated thread accepts connections off the network,
5862 then calls PostQueuedCompletionStatus() to wake up worker
5863 threads blocked on the completion port.
5866 *) Bring forward the --suexec-umask option which allows the
5867 builder to preset the umask for suexec processes. [Ken Coar]
5869 *) Add a -V flag to suexec, which causes it to display the
5870 compile-time settings with which it was built. (Only
5871 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
5873 *) Mod_include should always unset the content-length if the file is
5874 going to be passed through send_parsed_content. There is no to
5875 determine if the content will change before actually scanning the
5876 entire content. It is far safer to just remove the C-L as long
5877 as we are scanning it. [Ryan Bloom]
5879 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
5880 request and not Proxy-Authenticate.
5881 [Graham Leggett <minfrin sharp.fm>]
5883 Changes with Apache 2.0.14
5885 *) Fix content-length computation. We ONLY compute a content-length if
5886 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
5887 or we already have all the data. [Ryan Bloom]
5889 *) Report unbounded containers in the config file. Previously, a typo
5890 in the </container> directive could result in the rest of the config
5891 file being silently ignored, with undesired defaults used.
5894 *) Make the old_write filter use the ap_f* functions for the buffering.
5897 *) Move more code from the http module into the core server. This
5898 is core code, basically the default handler, the default input
5899 and output filters, and all of the core configuration directives.
5900 All of this code is required in order for the server to work, with or
5901 without HTTP. The server is closer to working without the HTTP
5902 module, although there is still more to do. [Ryan Bloom]
5904 *) Fix a number of SGI compile warnings throughout the server. Fix some
5905 bad parameters to apr_bucket_read(). Fix a bad statement in
5906 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
5907 consistently; we were mixing apr_time_t and time_t in invalid ways
5908 before. In load_file(), call apr_dso_error() instead of
5909 apr_strerror() so that we get a more specific string on some platforms.
5910 PR #6980 [Jeff Trawick]
5912 *) Allow modules to query the MPM about it's execution profile. This
5913 query API can and should be extended in the future, but for now,
5914 max_daemons, and threading or forking is a very good start.
5915 [Jon Travis <jtravis covalent.net>]
5917 *) Modify mod_include to send blocks of data no larger than 9k.
5918 Without this, mod_include will wait until the whole file is parsed,
5919 or the first tag is found to send any data to the client.
5920 [Paul J. Reder <rederpj raleigh.ibm.com>]
5922 *) Fix mod_info, so that <Directory> and <Location> directives are
5923 not displayed twice when displaying the current configuration.
5924 [Ryan Morgan <rmorgan covalent.net>]
5926 *) Add config directives to override DEFAULT_ERROR_MSG and
5927 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
5928 [Dan Rench <drench xnet.com>]
5930 *) Get mod_info building and loading on Win32. [William Rowe]
5932 *) Begin to move protocol independant functions out of mod_http. The goal
5933 is to have only functions that are HTTP specific in the http directory.
5936 Changes with Apache 2.0.13
5938 *) Don't assume that there will always be multiple calls to the byterange
5939 filter. It is possible that we will need to do byteranges with only
5940 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
5942 *) Move the error_bucket definition from the http module to the
5943 core server. Every protocol will need this ability, not just
5946 Changes with Apache 2.0.12
5948 *) Modify mod_file_cache to save pre-formatted strings for
5949 content-length and last-modified headers for performance.
5950 [Mike Abbot <mja trudge.engr.sgi.com>]
5952 *) Namespace protect IOBUFSIZ since it is exposed in the API.
5953 [Jon Travis <jtravis covalent.net>]
5955 *) Use "Basic" authentication instead of "basic" in ab, as the spec
5956 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
5958 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
5959 without ever filling it out. This fixes PR 7271.
5960 [Taketo Kabe <kabe sra-tohoku.co.jp> and
5961 Cliff Woolley <cliffwoolley yahoo.com>]
5963 *) Add a couple of GCC attribute tags to printf style functions.
5964 [Jon Travis <jtravis covalent.net>]
5966 *) Add the correct language tag for interoperation with the Taiwanese
5967 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
5969 *) Migrate the perchild MPM to use the new apr signal child, and
5970 APR thread functions. [Ryan Bloom]
5972 *) Close one copy of the CGI's stdout before creating the new process.
5973 The CGI will still have stdout, because we have already dup'ed it.
5974 This keeps Apache from waiting forever to send the results of a CGI
5975 process that has forked a long-lived child process.
5976 [Taketo Kabe <kabe sra-tohoku.co.jp>]
5978 *) Remove the rest of the pthreads functions from the threaded MPM.
5979 This requires the APR support for a signal thread that was just
5982 *) Make mod_dir use a fixup for sending a redirect to the browser.
5983 Before this, we were using a handler, which doesn't make much
5984 sense, because the handler wasn't generating any data, it would
5985 either return a redirect error code, or DECLINED. This fits the
5986 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
5988 *) Make the threaded MPM use APR threads instead of pthreads.
5991 *) Get mod_tls to the point where it actually appears to work in all cases.
5994 *) implement --enable-modules and --enable-mods-shared for "all" and
5995 "most". [Greg Stein]
5997 *) Move the threaded MPM to use APR locks instead of pthread locks.
6000 *) Rename mpmt_pthread to threaded. This is more in line with the
6001 fact that mpmt_pthread shouldn't be using pthreads directly, and
6002 it is a smaller name that doesn't tie into anything.
6005 *) Rename the module structures so that the exported symbol matches
6006 the file name, and it is easier to automate the installation
6007 process (generating LoadModule directives from the module filenames).
6010 *) Remove the coalesce filter. With the ap_f* functions, this filter
6011 is no longer needed. [Ryan Bloom]
6013 Changes with Apache 2.0.11
6015 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
6016 added feature of allowing a uid/gid per child process. If no
6017 uid/gid is specified, then Perchild behaves exactly like dexter.
6020 *) Get perchild building again. [Ryan Bloom]
6022 *) Don't disable threads just because we are using the prefork MPM.
6023 If somebody wants to compile without threads, they must now add
6024 --disable-threads to the configure command line. [Ryan Bloom]
6026 *) Begin to move the calls to update_child_status into common code, so
6027 that each individual MPM does not need to update the scoreboard itself.
6030 *) Allow mod_tls to compile under Unix boxes where openssl has been
6031 installed to the system include files.
6032 [Gomez Henri <new-httpd slib.fr>]
6034 *) Cleanup the mod_tls configure process. This should remove any need
6035 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
6036 configure doesn't check that yet. [Ryan Bloom]
6038 *) Add a very early prototype of SSL support (in mod_tls.c). It is
6039 vital that you read modules/tls/README before attempting to build
6042 *) Fix a potential seg fault on all platforms. David Reid fixed this
6043 on BEOS, but the problem could happen anywhere, so we don't want
6044 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
6046 *) Add new LogFormat directive, %D, to log time it takes to serve a
6047 request in microseconds. [Bill Stoddard]
6049 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
6050 SetOutputFilter. This corresponds nicely with the other Set
6051 directives, which operate on containers while the Add* directives
6052 tend to work directly on extensions. [Ryan Bloom]
6054 *) Cleanup the header handling a bit. This uses the apr_brigade_*
6055 functions for the buffering so that we don't need to compute
6056 the length of the headers before we actually create the header
6057 buffer. [Ryan Bloom]
6059 *) Allow filters to buffer data using the ap_f* functions. These have
6060 become macros that resolve directly to apr_brigade_*.
6063 *) Get the Unix MPM's to do a graceful restart again. If we are going
6064 to register a cleanup with ap_cleanup_scoreboard, then we have to
6065 kill the cleanup with the same function, and that function can't be
6066 static. [Ryan Bloom]
6068 *) Install all required header files. Without these, it was not
6069 possible to compile some modules outside of the server.
6072 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
6073 forward from 1.3 to 2.0, we missed a single line, which broke regex
6074 aliases. [Ryan Bloom]
6076 *) We have a poor abstraction in the protocol. This is a temporary
6077 hack to fix the bug, but it will need to be fixed for real. If
6078 we find an error while sending out a custom error response, we back
6079 up to the first non-OK request and send the data. Then, when we send
6080 the EOS from finalize_request_protocol, we go to the last request,
6081 to ensure that we aren't sending an EOS to a request that has already
6082 received one. Because the data is sent on a different request than
6083 the EOS, the error text never gets sent down the filter stack. This
6084 fixes the problem by finding the last request, and sending the data
6085 with that request. [Ryan Bloom]
6087 *) Make the server status page show the correct restart time, and
6088 thus the proper uptime. [Ryan Bloom]
6090 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
6091 should reduce the amount of duplicate code that is required to
6092 create CGI processes.
6093 [Paul J. Reder <rederpj raleigh.ibm.com>]
6095 *) ap_new_connection() closes the socket and returns NULL if a socket
6096 call fails. Usually this is due to a connection which has been
6097 reset. [Jeff Trawick]
6099 *) Move the Apache version information out of httpd.h and into release.h.
6100 This is in preparation for the first tag with the new tag and release
6101 system. [Ryan Bloom]
6103 *) Begin restructuring scoreboard code to enable adding back in
6104 the ability to use IPC other than shared memory.
6105 Get mod_status working on Windows again. [Bill Stoddard]
6107 *) Make mod_status work with 2.0. This will work for prefork,
6108 mpmt_pthread, and dexter. [Ryan Bloom]
6110 *) Correct a typo in httpd.conf.
6111 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
6113 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
6115 *) Get the correct IP address if ServerName isn't set and we can't
6116 find a fully-qualified domain name at startup.
6117 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
6119 *) Make mod_cgid work with SuExec. [Ryan Bloom]
6121 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
6122 'extra' stat's for user/group since they should never occur, and now
6123 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
6124 volumes. [William Rowe]
6126 *) Adopt apr features to simplify mod_includes. This changes the
6127 behavior of the USER_NAME variable, unknown uid's are now reported
6128 as USER_NAME="<unknown>" rather than the old user#000 result.
6129 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
6131 *) Adopt apr features for simplifing mod_userdir, and accept the new
6132 Win32/OS2 exceptions without hiccuping. [William Rowe]
6134 *) Replace configure --with-optim option by using and saving the
6135 environment variable OPTIM instead. This is needed because configure
6136 options do not support multiple flags separated by spaces.
6139 *) Fix some byterange handling. If we get a byte range that looks like
6140 "-999999" where that is past the end of the file, we should return
6141 a PARTIAL CONTENT status code, and return the whole file as one big
6142 byterange. This matches the 1.3 handling now. [Ryan Bloom]
6144 *) Make the error bucket a real meta-data bucket. This means that the
6145 bucket length is 0, and a read returns NULL data. If one of these
6146 buckets is passed down after the headers are sent, this data will
6147 just be ignored. [Greg Stein]
6149 *) The prefork MPM wasn't killing child processes correctly if a restart
6150 signal was received while the process was serving a request. The child
6151 process would become the equivalent of a second parent process. If
6152 we break out of the accept loop, then we need to do die after cleaning
6153 up after ourselves. [Ryan Bloom]
6155 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
6156 restarts. [Ryan Bloom]
6158 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
6159 the most optimal APR_FINFO_wanted bits. This spares Win32 from
6160 performing very expensive owner, group and permission lookups
6161 and allows the server to function until these apr_finfo_t fields
6162 are implemented under Win32. [William Rowe]
6164 *) Support for typedsafe optional functions - that is functions exported by
6165 optional modules, which, therefore, may or may not be present, depending
6166 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
6167 for sample code. [Ben Laurie]
6169 *) filters can now report an HTTP error to the server. This is done
6170 by sending a brigade where the first bucket is an error_bucket.
6171 This bucket is a simple bucket that stores an HTTP error and
6172 a string. Currently the string is not used, but it may be needed
6173 to output an error log. The http_header_filter will find this
6174 bucket, and output the error text, and then return
6175 AP_FILTER_ERROR, which informs the server that the error web page
6176 has already been sent. [Ryan Bloom]
6178 *) If we get an error, then we should remove all filters except for
6179 those critical to serving a web page. This fixes a bug, where
6180 error pages were going through the byterange filter, even though
6181 that made no sense. [Ryan Bloom]
6183 *) Relax the syntax checking of Host: headers in order to support
6184 iDNS. PR#6635 [Tony Finch]
6186 *) Cleanup the byterange filter to use the apr_brigade_partition
6187 and apr_bucket_copy functions. This removes a lot of very messy
6188 code, and hopefully makes this filter more stable.
6191 *) Remove AddModule and ClearModuleList directives. Both of these
6192 directives were used to ensure that modules could be enabled
6193 in the correct order. That requirement is now gone, because
6194 we use hooks to ensure that modules are in the correct order.
6197 *) When SuExec is specified, we need to add it to the list of
6198 targets to be built. If we don't, then any changes to the
6199 configuration won't affect SuExec, unless 'make suexec' is
6200 specifically run. [Ryan Bloom]
6202 *) Cleaned out open_file from mod_file_cache, as apr now accepts
6203 the APR_XTHREAD argument to open a file for consumption by
6204 parallel threads on win32. [William Rowe]
6206 *) Correct a bug in determining when we follow symlinks. The code
6207 expected a stat -1 result, not an apr_status_t positive error.
6208 Also check if the APR_FINFO_USER fields are valid before we
6209 follow the link. [William Rowe]
6211 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
6212 mpm_common.c. These functions are only valid on some platforms,
6213 so they should not be in the main-line code. [Ryan Bloom]
6215 *) Remove ap_chdir_file(). This function is not thread-safe,
6216 and nobody is currently using it. [Ryan Bloom]
6218 *) Do not try to run make depend if there are no .c files in the
6219 current directory, doing so makes `make depend` fail.
6222 *) Update highperformance.conf to work with either prefork or
6223 pthreads mpms. [Greg Ames]
6225 *) Stop checking to see if this is a pipelined request if we know
6226 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
6227 This keeps us from making an extra read call when serving a 1.0
6228 request. [Ryan Bloom and Greg Stein]
6230 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
6231 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
6232 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
6234 *) Fix the RFC number mentioned when complaining about a missing
6235 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
6237 *) Fix an endless loop in ab which occurred when ab was posting
6238 and the server dropped the connection unexpectedly.
6241 *) Fix a segfault while handling request bodies in ap_http_filter().
6242 This problem has been seen with mod_dav usage as well as with
6243 requests where the body was just being discarded. [Jeff Trawick]
6245 *) Some adjustment on the handling and automatic setting (via
6246 hints.m4) of various compilation flags (eg: CFLAGS). Also,
6247 add the capability to specify flags (NOTEST_CFLAGS and
6248 NOTEST_LDFLAGS) which are used to compile Apache, but
6249 not used during the configuration process. Useful for
6250 flags like "-Werror". [Jim Jagielski]
6252 *) Stop using environment variables to force debug mode or
6253 no detach. We now use the -D command line argument to
6254 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
6255 [Greg Stein, Ryan Bloom]
6257 *) Change handlers to use hooks. [Ben Laurie]
6259 *) Stop returning copies of filenames from both apr_file_t and
6260 apr_dir_t. We pstrdup the filenames that we store in the
6261 actual structures, so we don't need to pstrdup the strings again.
6264 *) mod_cgi: Fix some problems where the wrong error value was being
6265 traced. [Jeff Trawick]
6267 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
6270 *) Add generic hooks. [Ben Laurie]
6272 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
6274 *) Fix a segfault caused by mod_ext_filter when the external filter
6275 program does not exist. [Jeff Trawick]
6277 *) Fix an output truncation error when on an HTTP >= 1.0 request an
6278 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
6279 was served through mod_charset_lite (or anything else that would
6280 create a transient bucket in this size range). ap_bucket_make_heap()
6281 silently failed (fixed), transient_setaside() discovered it, but
6282 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
6284 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
6285 is that some browsers send extra lines at the end of POST requests, and
6286 we don't want to delay sending data back to the user just because the
6287 browser isn't well behaved. [Ryan Bloom]
6289 *) Get SuEXEC working again. We can't send absolute paths to suExec
6290 because it refuses to execute those programs. SuEXEC also wasn't
6291 always recognizing configuration changes made using the autoconf
6294 *) Allow the buildconf process to find the config.m4 files in the correct
6295 order. Basically, we can now name config.m4 files as config\d\d.m4,
6296 and we will sort them correctly when inserting them into the build
6297 process. [Ryan Bloom]
6299 *) Get mod_cgid to use apr calls for creating the actual CGI process.
6300 This also allows mod_cgid to use ap_os_create_priviledged_process,
6301 thus allowing for SuExec execution from mod_cgid. Currently, we do
6302 not support everything that standard SuExec supports, but at least
6303 it works minimally now. [Ryan Bloom]
6305 *) Allow SuExec to be configured from the ./configure command line.
6308 *) Update some of the docs in README and INSTALL to reflect some of
6309 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
6311 *) If we get EAGAIN returned from the call to apr_sendfile, then we
6312 need to call sendfile again. This gets us serving large files
6313 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
6315 *) Get the support programs building cleanly again.
6316 [Cliff Woolley <cliffwoolley yahoo.com>]
6318 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
6319 current directory logic now backs up over bin/ to determine the
6320 server root from the Apache.exe path.
6322 *) Apache/Win32 now follows the standard conventions of mod_foo.so
6323 loadable modules, dynamic libs are all named libfoo.dll, and the
6324 makefile.win populates the include, lib and libexec directories.
6326 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
6327 Apache gets IPv6 listening sockets by default. Additionally, the
6328 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
6329 numeric address strings (e.g., "Listen [fe80::1]:8080").
6332 *) Modify the install directory layout. Modules are now installed in
6333 modules/. Shared libraries should be installed in libraries/, but
6334 we don't have any of those on Unix yet. All install directories
6335 are modifyable at configure time. [Ryan Bloom]
6337 *) Install all header files in the same directory on Unix. [Ryan Bloom]
6339 *) Get the functions in server/linked into the server, regardless of
6340 which modules linked into the server. This uses the same hack
6341 for Apache that we use for APR and apr-util to ensure all of the
6342 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
6343 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
6344 the scripts a bit easier.
6347 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
6348 on the query, and remove IPv4 dependencies. [Jeff Trawick]
6350 *) Get all of the auth modules to the point that they will install and
6351 be loadable into the server. Our new build/install mechanism expects
6352 that all modules will have a common name format. The auth modules
6353 didn't use that format, so we didn't install them properly.
6356 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
6357 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
6359 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
6361 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
6362 after the end of the response. [Ryan Bloom]
6364 *) Get byterange requests working with responses that do not have a
6365 content-length. Because of the way byterange requests work, we have to
6366 have all of the data before we can actually do the byterange, so we
6367 can compute the content-length in the byterange filter.
6370 *) Get exe CGI's working again on Windows.
6373 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
6374 they keep track of whether or not their post config hook has been
6375 called before. Instead of a static variable (which is replaced when
6376 the DSO is loaded a second time), use userdata in the process pool.
6379 Changes with Apache 2.0a9
6381 *) Win32 now requires perl to complete the final install step for users
6382 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
6383 and installs the conf, htdocs and htdocs/manual directories.
6386 *) Make mod_include use a hash table to associate directive tags with
6387 functions. This allows modules to implement their own SSI tags easily.
6388 The idea is simple enough, a module can insert it's own tag and function
6389 combination into a hash table provided by mod_include. While mod_include
6390 parses an SSI file, when it encounters a tag in the file, it does a
6391 hash lookup to find the function that implements that tag, and passes
6392 all of the relevant data to the function. That function is then
6393 responsible for processing the tag and handing the remaining data back
6394 to mod_include for further processing.
6395 [Paul J. Reder <rederpj raleigh.ibm.com>]
6397 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
6398 fewer parameters: the local and remote socket addresses were removed
6399 from the parameter list because all required information is available
6400 via the APR socket. [Jeff Trawick]
6402 *) Distribution directory structure reorganized to reflect a
6403 normal source distribution with external install targets.
6406 *) The MPMs that need multiple segments of shared memory now create
6407 two apr_shmem_t variables, one for each shared memory allocation.
6408 the problem is that we can't determine how much memory will be required
6409 for shared memory allocations once we try to allocate more than one
6410 variable. The MM code automatically aligns the shared memory allocations,
6411 so we end up needing to pad the amount of shared memory we want based
6412 on how many variables will be allocated out of the shared memory segment.
6413 It is just easier to create a second apr_shmem_t variable, and two
6414 shmem memory blocks.
6417 *) Cleanup the export list a bit. This creates a single unified list of
6418 functions exported by APR. The export list is generated at configure
6419 time, and that list is then used to generate the exports.c file.
6420 Because of the way the export list is generated, we only export those
6421 functions that are valid on the platform we are building on.
6424 *) Enable logging the cookie with mod_log_config
6425 [Sander van Zoest <sander covalent.net>]
6427 *) Fix a segfault in mod_info when it reaches the end of the configuration.
6430 *) Added lib/aputil/ as a placeholder for utility functions which are not
6431 specific to the Apache HTTP Server (but do not make sense with APR).
6432 The first utility is "apu_dbm": a set of functions to work with DBM
6433 files. This first version can be compiled for SDBM or GDBM databases.
6436 *) Complete re-write of mod_include. This makes mod_include a filter that
6437 uses buckets directly. This has now served the FAQ correctly.
6438 [Paul Reder <rederpj raleigh.ibm.com>]
6440 *) Allow modules to specify the first filter in a sub_request when
6441 making the sub_request. This keeps modules from having to change the
6442 output_filter immediately after creating the sub-request, and therefore
6443 skip the sub_req_output_filter. [Ryan Bloom]
6445 *) Update ab to accept URLs with IPv6 literal address strings (in the
6446 format described in RFC 2732), and to build Host header fields in
6447 the same format. This allows IPv6 literal address strings to be
6448 used with ab. This support has been tested against Apache 1.3 with
6449 the KAME patch, but Apache 2.0 does not yet work with this format
6450 of the Host header field. [Jeff Trawick]
6452 *) Accomodate an out-of-space condition in the piped logs and the
6453 rotatelogs.c code, and no longer churn log processes for this
6454 condition. [Victor J. Orlikowski]
6456 *) Add support for partial writes with apr_sendfile() to core_output_filter.
6459 Changes with Apache 2.0a8
6461 *) Add a directive to mod_mime so that filters can be associated with
6465 *) Get multi-views working again. We were setting the path_info
6466 field incorrectly if we couldn't find the specified file.
6469 *) Fix 304 processing. The core should never try to send the headers
6470 down the filter stack. Always, just setup the table in the request
6471 record, and let the header filter convert it to data that is ready
6475 *) More fixes for the proxy. There are still bugs in the proxy code,
6476 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
6480 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
6483 *) APR: Add new apr_getopt_long function to handle long options.
6484 [B. W. Fitzpatrick <fitz red-bean.com>]
6486 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
6487 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
6488 hostname resolution/address string parsing and building
6489 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
6490 of one of the apr_sockaddr_t structures for a socket. Change
6491 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
6493 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
6494 I have proxied pages with it, cleanup will commence soon.
6497 *) Make the proxy work with filters. This isn't perfect, because we
6498 aren't dealing with the headers properly. [Ryan Bloom]
6500 *) Do not send a content-length iff the C-L is 0 and this is a head
6501 request. [Ryan Bloom]
6503 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
6504 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
6506 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
6508 *) Get the default_handler to stop trying to deal with HEAD requests.
6509 The idea is to let the content-length filter compute the C-L before
6510 we try to send the data. If we can get the C-L correctly, then we
6511 should send it in the HEAD response.
6514 *) The Header filter can now determine if a body should be sent based
6515 on r->header_only. The general idea of this is that if we delay
6516 deciding to send the body, then we might be able to compute the
6517 content-length correctly, which will help caching proxies to cache
6518 our data better. Any handler that doesn't want to try to compute
6519 the content-length can just send an EOS bucket without data and
6520 everything will just work.
6523 *) Add the referer to the error log if one is available.
6524 [Markus Gyger <mgyger itr.ch>]
6526 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
6527 change, the root of the configuration tree has been exposed to modules
6529 [Ryan Morgan <rmorgan covalent.net>]
6531 *) Get the core_output_filter to use the bucket interface directly.
6532 This keeps us from calling the content-length filter multiple times
6533 for a simple static request.
6536 *) We are sending the content-type correctly now.
6537 [Ryan Bloom and Will Rowe]
6539 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
6540 a bogus bytes-sent value when the only thing being sent was trailers
6541 and writev() returned an error (or EAGAIN). [Jeff Trawick]
6543 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
6544 hints file to determine which platforms define
6545 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
6548 *) APR: add apr_get_home_directory() [Jeff Trawick]
6550 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
6552 *) Not all platforms have INADDR_NONE defined by default. Apache
6553 used to make this check and define INADDR_NONE if appropriate,
6554 but APR needs the check too, and I suspect other applications will
6555 as well. APR now defines APR_INADDR_NONE, which is always a valid
6556 value on all platforms.
6557 [Branko Čibej <brane xbc.nu>]
6559 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
6560 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
6562 *) Relax the syntax checking of Host: headers in order to support
6563 iDNS. PR#6635 [Tony Finch]
6565 *) When reading from file buckets we convert to an MMAP if it makes
6566 sense. This also simplifies the default handler because the
6567 default handler no longer needs to try to create MMAPs.
6570 *) BUFF has been removed from the main server. The BUFF code will remain
6571 in the code until it has been purged from the proxy module as well.
6574 *) Byteranges have been completely re-written to be a filter. This
6575 has been tested, and I believe it is working correctly, but it could
6576 doesn't work for the Adobe Acrobat plug-in. The output almost matches
6577 the output from 1.3, the only difference being that 1.3 includes
6578 a content-length in the response, and this does not.
6581 *) APR read/write functions and bucket read functions now operate
6582 on unsigned integers, instead of signed ones. It doesn't make
6583 any sense to use signed ints, because we return the error codes,
6584 so if we have an error we should report 0 bytes read or written.
6587 *) Always compute the content length, whether it is sent or not.
6588 The reason for this, is that it allows us to correctly report
6589 the bytes_sent when logging the request. This also simplifies
6590 content-length filter a bit, and fixes the actual byte-reporing
6591 code in mod_log_config.c
6594 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
6595 it says, because it was only used by EOS and FLUSH buckets. Since
6596 neither of those are required at the end of a brigade, this was
6597 really signifying FLUSH_THE_DATA, but that can be determined better
6598 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
6599 buckets now return a length of 0, which is actually the amount of data
6600 read, so they make more sense.
6603 *) Allow the core_output_filter to save some data past the end of a
6604 request. If we get an EOS bucket, we only send the data if it
6605 makes sense to send it. This allows us to pipeline request
6606 responses. As a part of this, we also need to allocate mmap
6607 buckets out of the connection pool, not the request pool. This
6608 allows the mmap to outlive the request.
6611 *) Make blocking and non-blocking bucket reads work correctly for
6612 sockets and pipes. These are the only bucket types that should
6613 have non-blocking reads, because the other bucket types should
6614 ALWAYS be able to return something immediately.
6617 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
6618 server, but use Ctrl+Break to initiate a graceful restart
6619 instead of duplicating behavior. [John Sterling]
6621 *) Patch mod_autoindex to set the Last-Modified header based on
6622 the directory's mtime, and add the ETag header. [William Rowe]
6624 *) Merge the 1.3 patch to add support for logging query string in
6625 such a way that "%m %U%q %H" is the same as "%r".
6628 *) Port three log methods from mod_log_config 1.3 to 2.0:
6629 CLF compliant '-' byte count, method and protocol.
6632 *) Add a new LogFormat directive, %c, that will log connection
6633 status at the end of the response as follows:
6634 'X' - connection aborted before the response completed.
6635 '+' - connection may be kept-alive by the server.
6636 '-' - connection will be closed by the server.
6639 *) Expand APR for WinNT to fully accept and return utf-8 encoded
6640 Unicode file names and paths for Win32, and tag the Content-Type
6641 from mod_autoindex to reflect that charset if the feature
6642 macro APR_HAS_UNICODE_FS is true. [William Rowe]
6644 *) Compute the content length (and add appropriate header field) for
6645 the response when no content length is available and we can't use
6646 chunked encoding. [Jeff Trawick]
6648 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
6649 so that content input filters get dechunked data when using
6650 the default handler. Also removed REQUEST_CHUNKED_PASS.
6653 *) Add mod_ext_filter as an experimental module. This module allows
6654 the administrator to use external programs as filters. Currently,
6655 only filtering of output is supported. [Jeff Trawick]
6657 *) Most Apache functions work on EBCDIC machines again, as protocol
6658 data is now translated (again). [Jeff Trawick]
6660 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
6661 the EBCDIC support. They are noops on ASCII machines, so this
6662 type of translation doesn't have to be surrounded by #ifdef
6663 CHARSET_EBCDIC. [Jeff Trawick]
6665 *) Fix mod_include. tag commands work again, and the server will
6666 send the FAQ again. This also allows mod_include to set aside
6667 buckets that include partial buckets.
6668 [Ryan Bloom and David Reid]
6670 *) Add suexec support back. [Manoj Kasichainula]
6672 *) Lingering close now uses the socket directly instead of using
6673 BUFF. This has been tested, but since all we can tell is that it
6674 doesn't fail, this needs to be really hacked on.
6677 *) Allow filters to modify headers and have those headers be sent to
6678 the client. The idea is that we have an http_header filter that
6679 actually sends the headers to the network. This removes the need
6680 for the BUFF to send headers.
6683 *) Charset translation: mod_charset_lite handles translation of
6684 request bodies. Get rid of the xlate version of ap_md5_digest()
6685 since we don't compute digests of filtered (e.g., translated)
6686 response bodies this way anymore. (Note that we don't do it at
6687 all at the present; somebody needs to write a filter to do so.)
6690 *) Input filters and ap_get_brigade() now have a input mode parameter
6691 (blocking, non-blocking, peek) instead of a length parameter.
6694 *) Update the mime.types file to the registered media types as
6695 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
6698 *) Namespace protect some macros declared in ap_config.h
6701 *) Support HTTP header line folding with input filtering.
6704 *) Mod_include works again. This should still be re-written, but at
6705 least now we can serve an SHTML page again.
6708 *) Begin to remove BUFF from the core. Currently, we keep a pointer
6709 to both the BUFF and the socket in the conn_rec. Functions that
6710 want to use the BUFF can, functions that want to use the socket,
6711 can. They point to the same place.
6714 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
6715 [Tomas Ögren <stric ing.umu.se>]
6717 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
6718 associated pool goes away. (APR pipes on OS/2 were already had this
6719 logic.) This resolvs a fatal file descriptor leak with CGIs.
6722 *) The final line of the config file was not being read if there was
6723 no \n at the end of it. This was caused by apr_fgets returning
6724 APR_EOF even though we had read valid data. This is solved by
6725 making cfg_getline check the buff that was returned from apr_fgets.
6726 If apr_fgets return APR_EOF, but there was data in the buf, then we
6727 return the buf, otherwise we return NULL.
6730 *) Piped logs work again in the 2.0 series.
6733 *) Restore functionality broken by the mod_rewrite security fix:
6734 rewrite map lookup keys and default values are now expanded
6735 so that the lookup can depend on the requested URI etc.
6736 PR #6671 [Tony Finch]
6738 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
6739 security bug in some mass virtual hosting configurations
6740 that can allow a remote attacker to retrieve some files
6741 on the system that should be inaccessible. [Tony Finch]
6743 *) Add a pool bucket type. This bucket is used for data allocated out
6744 of a pool. If the pool is cleaned before the bucket is destroyed, then
6745 the data is converted to a heap bucket, allowing it to survive the
6749 *) Add a flush bucket. This allows modules to signal that the filters
6750 should all flush whatever data they currently have. There is no way
6751 to actually force them to do this, so if a filter ignores this bucket,
6752 that's life, but at least we can try with this.
6755 *) Add an output filter for sub-requests. This filter just strips the
6756 EOS bucket so that we don't confuse the main request's core output
6757 filter by sending multiple EOS buckets. This change also makes sub
6758 requests start to send EOS buckets when they are finished.
6761 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
6762 makes ap_bucket_destroy a return void, which is okay because it
6763 used to always return APR_SUCCESS, and nobody ever checked its
6764 return value anyway.
6765 [Cliff Woolley <cliffwoolley yahoo.com>]
6767 *) Remove the index into the bucket-type table from the buckets
6768 structure. This has now been replaced with a pointer to the
6769 bucket_type. Also add some macros to test the bucket-type.
6772 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
6773 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
6774 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
6775 All _VAR_ flavors changes to _DATA to be absolutely clear.
6778 *) Add support for /, //, //servername and //server/sharename
6779 parsing of <Directory> blocks under Win32 and OS2.
6780 [Tim Costello, William Rowe, Brian Harvard]
6782 *) Remove the function pointers from the ap_bucket type. They have been
6783 replaced with a global table. Modules are allowed to register bucket
6784 types and use then use those buckets.
6787 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
6788 once we finish writing the request body to the cgi child process;
6789 otherwise, the client doesn't hit EOF on stdin. Small request bodies
6790 worked without this change (for reasons I don't understand), but large
6791 ones didn't. [Jeff Trawick]
6793 *) Remove file bucket specific information from the ap_bucket type.
6794 This has been moved to a file_bucket specific type that hangs off
6795 the data pointer in the ap_bucket type.
6798 *) Input filtering now has a third argument. This is the amount of data
6799 to read from lower filters. This argument can be -1, 0, or a positive
6800 number. -1 means give me all the data you have, I'll deal with it and
6801 let you know if I need more. 0 means give me one line and one line
6802 only. A positive number means I want no more than this much data.
6804 Currently, only 0 and a positive number are implemented. This allows
6805 us to remove the remaining field from the conn_rec structure, which
6809 *) Big cleanup of the input filtering. The goal is that http_filter
6810 understands two conditions, headers and body. It knows where it is
6811 based on c->remaining. If c->remaining is 0, then we are in headers,
6812 and http_filter returns a line at a time. If it is not 0, then we are
6813 in body, and http_filter returns raw data, but only up to c->remaining
6814 bytes. It can return less, but never more.
6815 [Greg Ames, Ryan Bloom, Jeff Trawick]
6817 *) mod_cgi: Write all of the request body to the child, not just what
6818 the kernel would accept on the first write. [Jeff Trawick]
6820 *) Back out the change that moved the brigade from the core_output_filters
6821 ctx to the conn_rec. Since all requests over a given connection
6822 go through the same core_output_filter, the ctx pointer has the
6826 *) Fix another bug in the send_the_file() read/write loop. A partial
6827 send by apr_send would cause unsent data in the read buffer to
6828 get clobbered. Complete making send_the_file handle partial
6829 writes to the network.
6832 *) Fix a couple of type fixes to allow compilation on AIX again
6833 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
6835 *) Fix bug in send_the_file() which causes offset to be ignored
6836 if there are no headers to send.
6839 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
6840 filter. Useful for supporting Windows 9* with a binary
6841 compiled on Windows NT.
6844 Changes with Apache 2.0a7
6846 *) Reimplement core_output_filter to buffer/save bucket brigades
6847 across multiple calls to the core_filter. The brigade will be
6848 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
6849 thresholds are hit or the EOS bucket is received.
6852 *) Create experimental filter (buffer_filter) that coalesces bytes
6853 into one large buffer before invoking the next filter in the
6854 chain. This filter is particularly useful with the current
6855 implementation of mod_autoindex when it inserted above the
6856 chunk_filter. mod_autoindex generates a lot of brigades that
6857 containing buckets holding just a few bytes each. The
6858 buffer_filter coalesces these buckets into a single large bucket.
6861 *) Add apr_sendfile() support into the core_output_filter.
6864 *) Add apr_sendv() support into the core_output_filter.
6867 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
6868 [Mike Abbott <mja sgi.com>]
6870 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
6871 make much sense, because Apache uses buckets instead of BUFFs now.
6874 *) send_the_file now falls back to a read/write loop on platforms that
6875 do not have sendfile.
6876 [Ryan Bloom and Brian Havard]
6878 *) Install apachectl correctly, and substitute the proper values so
6879 that it works again. [Ryan Bloom]
6881 *) Better(??) handle platforms that lack sendfile().
6884 *) APR now has UUID generation/formatting/parsing support.
6887 *) Begin the http_filter. This is an input filter that understands
6888 the absolute basic amount required to parse an HTTP Request. The
6889 goal is to be able to split headers from request body before passing
6890 the data back to the other filters.
6893 *) Bring forward from 1.3.13 the config directory implementation
6896 *) install apxs if it is created
6899 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
6900 conversions. [William Rowe]
6902 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
6903 ap_add_output_filter(). [Jeff Trawick]
6905 *) Multiple build and configuration fixes
6908 -add datadir and localstatedir substitutions
6910 -fix logfilename misspelling
6911 -fix evaluation of installation dir variables and
6912 -replace $foobar by $(foobar) to be usefull in the makefile
6916 -add rules for cross-compiling in rules.mk. Okay, rule to check for
6917 $CC_FOR_BUILD is still missing
6918 -use CHECK_TOOL instead of CHECK_PROG for ranlib
6919 -add missing "AR=@AR@" to severaly Makefile.in's
6920 -cache result for "struct rlimit"
6921 -compile all helper programs with native and cross compiler
6922 and use the native version to generate header file
6923 [Rüdiger Kuhlmann <Tadu gmx.de>]
6925 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
6927 [Rüdiger Kuhlmann <Tadu gmx.de>]
6929 *) Fix a bug where a client which only sends \n to delimit header
6930 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
6931 message. Start working on ebcdic co-existance with input
6933 [William Rowe, Greg Ames]
6935 *) If mod_so is enabled in the server always create libexec, even
6936 if there are no modules installed in this directory. This is a
6937 requirement for APXS to work correctly.
6940 *) Connection oriented output filters are now stored in the
6941 conn_rec instead of the request_rec. This allows us to add the
6942 output filter in the pre-connection phase instead of the
6943 post_read_request phase, which keeps us from trying to write an
6944 error page before we have a filter to write to the network.
6945 [Ryan Bloom, Jeff Trawick, and Greg Ames]
6947 *) Cleaning up an mmap bucket no longer deletes the mmap. An
6948 mmap can be used across multiple buckets (default_handler with
6949 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
6950 the mmap itself can't be associated with the bucket.
6953 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
6956 *) Radical surgery to improve mod_isapi support under Win32.
6957 Includes a number of newer ServerSupportFunction calls, support
6958 for ReadClient (in order to retrieve POSTs greater than 48KB),
6959 and general bug fixes to more reliably load ISAPI .dll's and
6960 prevent leaking handle resources. Note: There are still
6961 discrepancies between IIS's and Apache's ServerVariables, and
6962 async calls are still not supported. Additional warnings are
6963 logged to facilitate debugging of unsupported ISAPI calls.
6966 *) Add input filtering to Apache. The basic idea for the input
6967 filters is the same as the ideas for output filters. The biggest
6968 difference is that instead of calling ap_pass_brigade, ap_get_brigade
6969 should be called, and the order of execution for the filter itself is
6970 different. When writing an output filter, a brigade is passed in,
6971 and filters operate directly on that brigade, when done, they call
6972 ap_pass_brigade. Input filters are the exact opposite. Because input
6973 is not a push operation, filters first call ap_get_brigade. When this
6974 function returns, the input filter will be left with a valid brigade.
6975 The input filter should then operate on the brigade, and return.
6978 *) Fix building on BSD/OS using its native make. The build system
6979 falls back to the BSD .include directive on that host platform.
6982 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
6983 SHA1 and plaintext password encodings. Make feature tests a
6984 bit more flexible. [William Rowe]
6986 *) Charset translation: mod_charset_lite handles output content
6987 translation in a filter. mod_charset_lite no longer ignores
6988 subrequests. A bunch of cruft related to BUFF's support for
6989 translating request and response bodies was removed.
6992 *) Move the addition of the CORE filter to the post_read_request
6993 hook in http_core.c. This removes the need to add the filter in
6994 multiple places and allows for an SSL module to be added much
6995 simpler. [Ryan Bloom]
6997 *) SECURITY: CVE-2000-0913 (cve.mitre.org)
6998 Fix a security problem that affects certain configurations of
6999 mod_rewrite. If the result of a RewriteRule is a filename that
7000 contains expansion specifiers, especially regexp backreferences
7001 $0..$9 and %0..%9, then it may be possible for an attacker to
7002 access any file on the web server. [Tony Finch]
7004 *) Fix a bug where errors that are detected during early request parsing
7005 don't produce visible HTTP error messages at the browser, because
7006 the core_filter wasn't present. [Greg Ames]
7008 *) Provide apr_socklen_t as a portability aid.
7009 [Victor J. Orlikowski]
7011 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
7012 as well as a comment arg to the add, adduser and update cmds.
7013 update allows the user to clear or preserve pw/groups/comment.
7014 Fixed a bug in dbmmanage that prevented the check option from
7015 parsing a password followed by :group... text. Corrected the
7016 seed calcualation for Win32 systems, and added -lsdbm support.
7019 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
7022 *) Avoid a segfault when parsing .htaccess files. An
7023 uninitialized tree pointer was passed to ap_build_config().
7026 *) Change the way that inet_addr & inet_network are checked for
7027 in APR's configure process to allow BeOS BONE to correctly
7028 find them. With this change BeOS BONE now builds from source
7029 with no problems. [David Reid]
7031 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
7032 the end of the parameters to execve() was stored in the wrong
7033 location, overlaying the storage beyond the newargs[] array and
7034 also passing uninitialized storage to execve(), which would
7035 sometimes fail with EFAULT. [Jeff Trawick]
7037 *) Fix a bug parsing configuration file containers. With a sequence
7038 like this in the config file
7040 <IfModule mod_kilroy.c>
7043 <IfModule mod_lovejoy.c>
7048 the second container would be terminated at the blank line due to
7049 sediment in the buffer from reading the prior </IfModule> and an
7050 error message would be generated for the real </IfModule> for the
7051 second container. Also due to this problem, any two characters
7052 could be used for "</" in the close of a container.
7055 *) ap_add_filter prototype changed to remove the ctx pointer. The
7056 pointer still remains in the filter structure, but it can not be
7057 a part of the ap_add_filter prototype. The reason is that when
7058 the core uses AddFilter to add a filter to the stack it doesn't
7059 know how to allocate the ctx pointer, or even how much memory should
7060 be allocated. The filters will have to be responsible for allocating
7061 the ctx memory when they need it.
7064 *) Add an AddFilter directive. This directive takes a list of filters
7065 that should be activated for the requested resource.
7068 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
7069 some other platforms). [Jeff Trawick]
7071 *) Modify mod_include to be a filter. Currently, it has only been tested
7072 on actual files, but it should work for CGI scripts too.
7075 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
7076 writes. apr_flush() for Unix: handle interrupted writes.
7079 *) NameVirtualHost can now take "*" as an argument instead of
7080 an IP address. This allows you to create a purely name-based
7081 virtual hosting server that does not have any IP addresses in
7082 the configuration file and which ignores the local address
7083 of any connections. PR #5595, PR #4455 [Tony Finch]
7085 *) Fix some compile warnings in mod_mmap_static.c
7086 [Mike Abbott <mja sgi.com>]
7088 *) Fix chunking problem with CGI scripts. The general problem was that
7089 the CGI modules were adding an EOS bucket and then the core added an
7090 EOS bucket. The chunking filter finalizes the chunked response when it
7091 encounters an EOS bucket. Because two EOS buckets were sent, we
7092 finalized the response twice. The fix is to make sure we only send one
7093 EOS, by utilizing a flag in the request_rec.
7096 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
7097 and Win32. Previously, the first read from an apr_file_t set up via
7098 apr_put_os_file() would return a '\0'. [Jeff Trawick]
7100 *) Mod_cgid now creates a single element bucket brigade, with a pipe
7101 bucket, instead of using BUFF's and ap_r*.
7104 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
7105 [Mike Abbott <mja sgi.com>]
7107 *) Remove ap_bopenf from buff code. This required modifying the file_cache
7108 code to use APR file's directly instead of going through BUFFs.
7111 *) Fix compile break on some platforms for mod_mime_magic.c
7112 [John K. Sterling <sterling covalent.net>]
7114 *) Fix merging of AddDefaultCharset directive.
7115 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
7117 *) Minor revamp of the rlimit sections of code. We now test
7118 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
7119 is now "available" even if the platform doesn't support
7120 the rlimit family (it's just a noop though). [Jim Jagielski]
7122 *) Migrate the pre-selection of which MPM to use for specific
7123 platforms to hints.m4, which contains (or should contain)
7124 all platform specific "hints". [Jim Jagielski]
7126 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
7129 *) Add tables with non-string/binary values to APR.
7132 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
7135 *) Update PCRE to version 3.2. [Ryan Bloom]
7137 *) Change the way buckets' destroy functions are called so that
7138 they can be more directly used when changing the type of a
7139 bucket in place. [Tony Finch]
7141 *) Add generic support for reference-counting the resources used by
7142 buckets, and alter the HEAP and MMAP buckets to use it. Change
7143 the way buckets are initialised to support changing the type of
7144 buckets in place, and use it when setting aside TRANSIENT buckets.
7145 Change the implementation of TRANSIENT buckets so that it can be
7146 mostly shared with IMMORTAL buckets, which are now implemented.
7149 Changes with Apache 2.0a6
7151 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
7153 *) Add a chunking filter to Apache. This brings us one step closer
7154 to removing BUFF. [Ryan Bloom]
7156 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
7157 added to the stack is the last filter to be called. [Ryan Bloom]
7159 *) Apache 2.0 has been completely documented using Scandoc. The
7160 docs can be generated by running 'make docs'. [Ryan Bloom]
7162 *) Add filtered I/O to Apache. This is based on bucket brigades,
7163 Currently the buckets still use BUFF under the covers, but that
7164 should change quickly. The only currently written filter is the
7165 core filter which just calls ap_bwrite. [The Apache Group]
7167 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
7168 built with thread support. [Jeff Trawick]
7170 *) Abort configuration if --with-layout was specified and there's
7171 no layout definition file. [Ken Coar]
7173 *) Add support for '--with-port=n' option to configure. [Ken Coar]
7175 *) Add support for extension methods for the Allow response header
7176 field, and an API routine for accessing r->allowed and the
7177 list of extension methods in a unified manner. [Ken Coar]
7179 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
7180 [Rob Simonson <simo us.ibm.com>]
7182 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
7183 APACHE_XLATE builds. [Jeff Trawick]
7185 *) A configuration file parsing problem was fixed. When the
7186 configuration file started with an IfModule/IfDefine container,
7187 only the last statement in the container would be retained.
7190 Changes with Apache 2.0a5
7192 *) Perchild is serving pages after passing them to different child
7193 processes. There are still a lot of bugs, but this does work. I
7194 have made requests against the same installation of Apache, and had
7195 different servers use different user IDs to serve the responses.
7196 This change moves to using socketpair instead of an AF_UNIX socket.
7199 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
7200 It can't seem to pass between child processes yet, but I think we
7201 are closer now than before. This moves us back to using Unix
7202 Domain Sockets. [Ryan Bloom]
7204 *) libapr functions and types renamed with apr_ prefix.
7205 #include "apr_compat.h" for 1.3.x backwards compat
7208 *) Fix problems with APR sockaddr handling on Win32. It didn't always
7209 return the right information on the local socket address.
7210 [Gregory Nicholls <gnicholls level8.com>]
7212 *) ap_recv() on Win32: Set bytes-read to 0 on error.
7213 [Gregory Nicholls <gnicholls level8.com>]
7215 *) Add an option to not detach from the controlling terminal without
7216 going into single process mode. This allows for much easier
7217 debugging of the process startup code. [Ryan Bloom]
7219 *) ab: don't use perror() to report the failure of an APR function.
7222 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
7223 scoreboard on graceful restarts.
7226 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
7227 An invalid ap_proc_t was passed to ap_create_process().
7230 *) Allow modules to register filters. Those filters are still
7231 never called, but this is a step in the right direction.
7232 [Ryan Bloom and Greg Stein]
7234 *) Register the mod_cgid daemon process for cleanup so that it is
7235 killed at termination if it does not die when the parent gets
7236 SIGTERM. This change is to fix occasional problems where the
7237 process stays around. Bugs in similar logic in mod_rewrite and
7238 mod_include were also fixed. [Jeff Trawick]
7240 *) Fix a bug in the time handling. Basically, we were imploding a time
7241 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
7242 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
7243 uses those two fields to adjust the time value. Because of the HTTP
7244 spec, both of those values can be zero'ed out safely. This fixes
7245 the bug correctly. [Ryan Bloom]
7247 *) Fix a couple of place in the Windows code where the wrong error
7248 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
7250 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
7252 *) Added the APR_EOL_STR macro for platform dependent differences in
7253 logfiles and other raw text (such as all APR files). Fixes logfiles
7254 not terminated with cr/lf sequences in Win32. [William Rowe]
7256 *) Move all strings functions in APR to src/lib/apr/strings and create
7257 apr_strings.h for the prototypes. [Ryan Bloom]
7259 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
7260 to repeat the syscall until we stop getting EINTR. I noticed a
7261 related problem at termination (SIGTERM) on FreeBSD when using
7262 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
7263 implementation work properly with child init. Previously, ap_lock()
7264 was essentially a no-op because all children were using different
7265 locks and thus nobody ever blocked. [Jeff Trawick]
7267 *) The htdocs/ tree has been moved out of the CVS source tree into
7268 a separate area for easier development. This has NO EFFECT on
7269 end-users or Apache installations. [Ken Coar]
7271 *) Integrate the mod_dav module for WebDAV protocol handling. This
7272 adds the dav and dav_fs modules, the SDBM library, and additional
7273 XML handling utilities. [Greg Stein]
7275 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
7278 *) Update the lib/expat-lite/ library (bring forward changes from
7279 the Apache 1.3 repository). [Greg Stein]
7281 *) If sizeof(long long) == sizeof(long), then prefer long in APR
7282 configure.in. [Dave Hill <ddhill zk3.dec.com>]
7284 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
7285 machines where sendfile is detected, but nobody has written ap_sendfile.
7286 [Dave Hill <ddhill zk3.dec.com>]
7288 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
7290 *) ab would start up more connections than needed, then quit when the
7291 desired number were finished. Also fixed a logic error involving
7292 ab keepalives. [Victor J. Orlikowski]
7294 *) WinNT: Implement non-blocking pipes with timeouts to communicate
7295 with CGIs. Apache 2.0a4 had non-blocking pipes but without
7296 timeouts (i.e, if a timeout was specified, the pipe reverted to
7297 a full blocking pipe). Now the behaviour is more in line with
7298 Unix non-blocking pipes.
7301 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
7302 cache open file handles along with accept socket reuse enables
7303 Apache 2.0 to serve non-keepalive requests for static files at
7304 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
7305 and Apache 2.0 will serve almost 1200 rps on my system).
7308 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
7309 supports two config directives, mmapfile (same behavious as
7310 mod_mmap_static) and cachefile. Use the cachefile directive
7311 to cache open file handles. This directive only works on systems
7312 that have implemented the ap_sendfile API. cachefile works today
7313 on Windows NT, but has not been tested on any flavors of Unix.
7316 *) Cleanup the configuration. With the last few changes the
7317 configuration process automatically:
7318 inherits information about how to build from APR. Allowing
7319 APR to inform Apache that it should or should not use -ldl
7321 Detects which mod_cgi should be used mod_cgi or mod_cgid,
7322 based on the threading model
7324 Apache calls APR's configure process before finishing it's
7325 configuration processing, allowing for more information flow
7330 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
7331 with non-zero argument makes the socket non-blocking. BeOS and
7332 OS/2 already worked this way. [Jeff Trawick]
7334 *) ap_close() now calls ap_flush() for buffered files, so write
7335 operations work a whole lot better on buffered files.
7338 *) Fix error messages issued from MPMs which explain where to change
7339 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
7342 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
7343 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
7344 now the way that the blocking state of a pipe is manipulated.
7345 ap_block_pipe() is gone. [Jeff Trawick]
7347 *) Correct the problem where the only local host name that the IP stack
7348 can discover are 'undotted' private names. If no fully qualified
7349 domain name can be identified, the default ServerName will be set to
7350 the machine's IP address string. A warning is always provided if the
7351 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
7353 *) Repair problems with config file processing which caused segfault
7354 at init when virtual hosts were defined and which caused ServerName to
7355 be ignored when there was no valid DNS setup. [Jeff Trawick]
7357 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
7359 *) Add ap_sendfile implementation for AIX
7360 [Victor J. Orlikowski]
7362 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
7363 apr_network_io.h, and apr_thread_proc.h.
7364 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
7366 *) Bring the allocation and pool debugging code back into a working
7367 state. This will need to be tested as so far it's only been used on
7370 *) Change configuration command setup to be properly typesafe when in
7371 maintainer mode. Note that this requires a compiler that can initialise
7372 unions. [Ben Laurie]
7374 *) Turn on buffering for config file reads. Part of this was to
7375 repair buffered I/O support in Unix and implement buffered
7376 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
7378 *) Win32: Fix problem where UTC offset was not being set correctly
7379 in the access log. Problem reported on news group by Jerry Baker.
7382 *) Fix segfault when reporting this type of syntax error:
7383 "</container> without matching <container> section", where
7384 container is VirtualHost or Directory or whatever.
7387 *) SECURITY: CVE-2000-1204 (cve.mitre.org)
7388 Prevent the source code for CGIs from being revealed when
7389 using mod_vhost_alias and the CGI directory is under the document root
7390 and a user makes a request like http://www.example.com//cgi-bin/cgi
7391 as reported in <news:960999105.344321 ernani.logica.co.uk>
7394 *) Add support for the new Beos NetwOrking Environment (BONE)
7397 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
7398 final input char is incomplete; ap_bwrite_xlate() now handles
7399 incomplete final input chars. [Jeff Trawick]
7401 *) Yet another update to saferead/halfduplex stuff -- need to ensure
7402 that a bhalfduplex call occurs before logging or else DNS and
7403 such can delay the last packet of the response. [Dean Gaudet]
7405 *) Some syscall reduction in APR on unix -- don't seek when setting
7406 up an mmap; and don't fcntl() more than once per socket.
7409 *) When mod_cgid is started as root, the cgi daemon now switches
7410 to the configured User/Group (like other httpd processes)
7411 instead of continuing as root. [Jeff Trawick]
7413 *) The prefork MPM now uses an APR lock for the accept() mutex.
7414 It has not been getting a lock at all recently. httpd -V now
7415 displays APR's selection of the lock mechanism instead of the
7416 symbols previously respected by prefork. [Jeff Trawick]
7418 *) Change the mmap() feature test to check only for existence.
7419 The previous check required features not used by Apache.
7422 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
7423 sometimes mangled. The len parm to accept() was not
7424 initialized, leading sometimes to an endless loop of failed
7425 accept() calls on OS/390 and anywhere else that failed the call
7426 if the len was negative. Use <sys/un.h> for struct sockaddr_un
7427 instead of declaring it ourselves to fix a compilation problem
7428 on Solaris. [Jeff Trawick]
7430 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
7432 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
7434 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
7436 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
7437 initialization if ALLOC_DEBUG is defined; no known symptom
7438 otherwise. [Jeff Trawick]
7440 *) Fix typo in configure script when checking for mod_so. bash
7441 doesn't seem to have a problem but /bin/sh on Solaris does.
7442 Symptom: "./configure: test: unknown operator =="
7445 *) Rebind the Win32 NT and 9x services control into the MPM.
7446 All console, WinNT SCM and Win9x pseudo-service control code is
7447 now wrapped within the WinNT MPM.
7450 *) Make a copy of getenv("PATH") before storing for later use. Some
7451 getenv() implementations use the same storage for successive calls.
7452 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
7454 *) Server Tokens work in 2.0 again. This also propogates the change
7455 to allow just the product name in the server string using
7459 Changes with Apache 2.0a4
7461 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
7462 won't need to call it. [Greg Ames, Jeff Trawick]
7464 *) Move pre_config hook call to between configuration read and config
7465 tree walk. This allows all modules to implement pre_config hooks
7466 and know that they will be called at an appropriate time.
7469 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
7472 *) Add pre-config hooks back to all modules.
7475 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
7476 ContentDigest enabled and we can't/don't mmap the file.
7479 *) We now report the correct line number for syntax errors in config
7480 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
7482 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
7483 related bugs, and changed shmem/locking to use apr API. Shared-mem
7484 is currently disabled, however, because of problems with graceful
7485 restarts. [Ronald Tschalär]
7487 *) Fix corruption of IFS variable in --with-module= handling.
7488 Depending on the user's shell or customization thereof, there
7489 would be errors generating ap_config_auto.h later in the configure
7490 procedure. [Jeff Trawick]
7492 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
7493 isn't used (as in 1.3), except that on Unix it is now logged via
7494 ap_log_rerror() instead of by the child having STDERR_FILENO refer
7495 to the error log. [Greg Ames, Jeff Trawick]
7497 *) Add '-D' argument processing for run time configuration defines.
7500 *) Organize http_main.c as independent code, such that no code or
7501 global data is exported from it. WIN32 will dynamically link it
7502 to the server core, so this will prevent mutual dependency.
7505 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
7506 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
7509 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
7510 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
7512 *) Add mod_charset_lite for configuring character set translation.
7515 *) Add '-n' option to htpasswd to make it print its user:pw record
7516 on stdout rather than having to frob a text file. [Ken Coar]
7518 *) Fix saferead. Basically, we flush the output buffer if a read on the
7522 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
7523 a conversion is single-byte only. [Jeff Trawick]
7525 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
7526 the BeOS 5.0 documentation says that shutdown doesn't work yet.
7529 *) Fix some minor errors where pid was being manipulated as an int
7530 instead of the portable pid_t. [Roy Fielding]
7532 *) Fix some error log prints that were printing the pointer to a
7533 structure rather than the pid within the structure.
7534 [Jeff Trawick, Roy Fielding]
7536 *) ab: Fix a command-line processing bug; track bad headers in
7537 err_response; support reading headers up to 2K.
7538 [Ask Bjoern Hansen <ask valueclick.com>]
7540 *) Fix ap_resolve_env() so that it handles new function added in a prior
7541 alpha (see "Added the capability to do ${ENVVAR} constructs in the
7542 config file.") as well as the constructs used by mod_rewrite.
7543 [Paul Reder <rederpj raleigh.ibm.com>]
7545 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
7547 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
7548 APR to perform translation, instead of accessing the hard-coded tables
7549 in 1.3's ebcdic.c. [Jeff Trawick]
7551 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
7554 *) Add the ability to hook into the config file reading phase. Basically
7555 if a directive is specified EXEC_ON_READ, then when that directive is
7556 read from the config file, the assocaited function is executed. This
7557 should only be used for those directives that must muck with HOW the
7558 server INTERPRETS the config. This should not be used for directives
7559 that re-order or replace items in the config tree. Those changes should
7560 be made in the pre-config step.
7563 *) Add mod_example to the build system.
7566 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
7567 byte character sets. [Jeff Trawick]
7569 *) Pick up various EBCDIC fixes from 1.3 (from Martin
7570 Kraemer and Oliver Reh originally according to the change log).
7573 *) Fix a couple of problems in RFC1413 support (controlled by the
7574 IdentityCheck directive). Apache did not build the request string
7575 properly and more importantly Apache would loop forever if the
7576 would-be ident server dropped the connection before sending a
7577 properly terminated response. [Jeff Trawick]
7579 *) apxs works in 2.0.
7582 *) Reliable piped logs work in 2.0.
7585 *) Introduce a hash table implementation into APR to be used for
7586 replacing tables and other random data structures in Apache.
7589 *) Add some more error reporting to htpasswd in the case of problems
7590 generating or accessing the temporary file. Also, pass in a
7591 buffer if the implementation knows how to use it (i.e., if L_tmpnam
7592 is defined). [Ken Coar]
7594 *) Configure creates config.nice now containing your configure
7595 options. Syntax: ./config.nice [--more-options]
7598 *) Fix various return code problems in APR on Win32. For most of
7599 these, APR was returning APR_EEXIST instead of GetLastError()/
7600 WSAGetLastError(). [Jeff Trawick]
7602 *) Make piped logs work again in version 2.0
7605 *) Add VPATH support to UNIX build system of Apache and APR.
7608 *) Fix ap_tokenize_to_argv to respect the const arguments that are
7612 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
7613 Patch submitted to author.
7616 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
7617 /sbin in PATH on FreeBSD (all submitted to rse previously)
7620 *) Fix building Pthread-based MPMs on OpenBSD
7621 [Sascha Schumann] PR#26
7623 *) Fix ap_readdir() problem on systems where d_name[] field in
7624 struct dirent is declared with only one byte. (This problem only
7625 affected multithreaded builds.) This caused a segfault during
7626 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
7627 least). [Jeff Trawick]
7629 *) Fix some make-portability problems on at least Tru64, Irix
7631 [Sascha Schumann] PR#18, PR#39
7633 *) Add ap_sigwait() to support old-style sigwait() on systems
7634 like OS/390 and UnixWare.
7637 *) Add POSIX-thread flags for more platforms.
7640 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
7641 (on Unix, at least) to handle resolver errors. Fix a bug in
7642 the definition of APR_ENOMEM so that ap_strerror() can spit
7643 out the correct error message for it.
7646 Changes with Apache 2.0a3
7648 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
7651 *) API: *HOOK* macros now have an AP_ prefix
7654 *) Win32: Eliminate redundant calls to initialize winsock.
7655 [Tim Costello <timcostello ozemail.com.au>]
7657 *) Fix bugs initializing ungetchar for pipes.
7658 [Chia-liang Kao <clkao CirX.ORG>]
7660 *) The ab program in the src/support directory is now portable using
7664 *) Support directory is being compiled when the server is built
7667 *) The configure option --with-program-name has been added to allow
7668 developers to rename the executable at configure time. This also
7669 changes the name of the config files to match the executable's name.
7672 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
7673 containing version numbers. [Martin Pool]
7675 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
7676 Unix; access_log and error_log now created with these perms; non-
7677 Unix is unaffected [Jeff Trawick]
7679 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
7680 Replaced more magic numbers with MD5_DIGESTSIZE.
7681 [William Rowe, Roy Fielding]
7683 *) Win32: Get mod_auth_digest compiling and added to the Windows
7684 build environment. Not tested and I'd be suprised if it
7685 actually works. [Bill Stoddard]
7687 *) Revamp the Win32 make environment. Makefiles have been removed and
7688 Apache.dsw created to bring together all the pieces. Create new file
7689 os/win32/BaseAddr.ref to define module base addresses (to prevent
7690 dll relocation at start-up).
7691 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
7693 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
7694 of the \015, \012, and \015\012 constants with macros.
7697 *) Add ap_xlate_open() et al for translation of text between different
7698 character sets. The initial implementation requires iconv().
7701 *) More FAQs and answers from comp.infosystems.www.servers.unix.
7702 [Joshua Slive <slive finance.commerce.ubc.ca>]
7704 *) CGI output is being timed out now.
7707 *) Fix the problem with dieing quietly. dupfile now takes a pool which
7708 is used by the new apr file. There is no reason to create a new file
7709 with the same lifetime as the original file.
7712 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
7713 module base addresses. This will help shooting seg faults
7714 in the field. [William Rowe <wrowe lnd.com>]
7716 *) Update Apache on Windows documentation. Add new document
7717 describing how to compile Apache on Windows.
7718 [William Rowe <wrowe lnd.com>]
7720 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
7721 microseconds instead of seconds. Some storage leaks and other
7722 minor bugs in related code were fixed. [Jeff Trawick]
7724 *) Win32: First cut at getting mod_isapi working under 2.0
7725 [William Rowe <wrowe lnd.com>]
7727 *) First stab at getting mod_auth_digest working under 2.0
7728 quick change summary:
7729 - moved the random byte generation (ap_generate_random_bytes) into APR
7730 - now uses ap_time_t
7731 - compiles and runs on linux
7733 [Brian Martin <bmartin penguincomputing.com>]
7735 *) Win32: Move the space stripping of physical service names
7736 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
7737 unresolved symbol. Add dependency checking to the
7738 CreateService call to ensure TCPIP and AFP (winsock) is started
7740 [William Rowe <wrowe lnd.com>]
7742 *) Win32: Add code to perform latebinding on functions that may
7743 not exist on all levels of Windows where Apache runs. This
7744 is needed to allow Apache to start-up on Win95/98. All calls
7745 to non portable functions should be protected with
7746 ap_oslevel checks to prevent runtime segfaults.
7747 [William Rowe <wrowe lnd.com>]
7749 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
7751 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
7753 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
7754 This addresses PR 1623. Still need to address timing out runaway
7755 CGI scripts. [Bill Stoddard]
7757 *) Win32: Make ap_stat Windows 95/98 friendly
7758 [William Rowe <wrowe lnd.com>]
7760 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
7761 always fail. Need to initialise the dwOSVersionInfoSize member of the
7762 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
7765 The patch also enhances ap_get_oslevel (and the associated enum) to
7766 handle selected service packs for NT4, and adds recognition for
7767 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
7768 we can use ReadFileScatter and WriteFileGather in readwrite.c.
7769 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
7771 *) Get mod_rewrite building and running, and mod_status building for Win NT
7772 [Allan Edwards <ake raleigh.ibm.com>]
7774 *) Patch to port mod_auth_db to the 2.0 api and also to support
7775 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
7776 2.7.7. It should work with version 1 as well but I haven't tested it.
7777 [Brian Martin <bmartin penguincomputing.com>]
7779 *) Get APR DSO code working under Windows. Includes cross platform
7781 [<Tim.Costello BTFinancialgroup.com>]
7783 *) Fix some of the Windows APR time functions.
7786 *) FAQ changes related to tidying up historical documents on the web site.
7787 [Joshua Slive <slive finance.commerce.ubc.ca>]
7789 *) Move Windows DSO code into APR.
7792 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
7793 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
7794 at build time. At this point, the server will not compile on Windows because
7795 of the recent DSO commits. Fixing those next.
7796 [Bill Rowe & Bill Stoddard]
7798 *) Added error checking for file I/O APR routines.
7799 [Jon Travis <jtravis covalent.net>]
7801 *) APR: Don't use the values of resolver error codes for the
7802 corresponding APR error codes. On Unix and Win32, return the
7803 proper APR error code after a resolver error. [Jeff Trawick]
7805 Changes with Apache 2.0a2
7807 *) Renamed the executable back to httpd on all platforms other
7811 *) Allow BeOS to survive restarts, log properly and a few
7812 small things it had problems with due to the way it setup
7813 users and groups. [David Reid]
7815 *) Get mod_rewrite working with APR locks
7816 [Paul Reder <rederpj raleigh.ibm.com>]
7818 *) Actually remove the sempahore when the lock cleanup routine
7819 is called on BeOS. [David Reid]
7821 *) Clear hook registrations between reads of the config file.
7822 When DSOs are unloaded and re-loaded the old hook pointers may
7823 no longer be valid. This fix eliminates potential segfaults.
7824 [Allan Edwards <ake raleigh.ibm.com>]
7826 *) Fix a problem with Sigfunc not being defined or bypassed
7827 if sigaction() wasn't found. [Jim Jagielski]
7829 *) Fix the locking mechanism on BSD variants. They now use fcntl
7830 locks. This allows the server to start and serve pages.
7833 *) First cut at getting the Win32 installer to work
7834 [William Rowe <wrowe lnd.com>]
7836 *) Get htpasswd compiling under Windows
7837 [William Rowe <wrowe lnd.com>]
7839 *) Change the log message for a bind() failure to show the
7840 interface and port number. [Jeff Trawick]
7842 *) Import the documentation from 1.3.12 and bring parts of it
7843 up-to-date with respect to the changes that have occurred
7847 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
7848 now logged correctly on BeOS.
7851 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
7852 Makefile.win includes the same user interface as the old
7854 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
7856 *) Win32 exec now uses COMSPEC environment string for command
7857 shell path resolution.
7858 [William Rowe <wrowe lnd.com>] PR#3715
7860 *) Win32: ap_connect() was not returning correct error condition
7862 [Allen Prescott <allen clanprescott.com>]
7864 *) Win32: ap_open() was broken on Win9x because an NT-specific
7865 flag was passed to CreateFile. ap_puts() added an unnecessary
7867 [Jeff Trawick <trawick us.ibm.com>]
7869 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
7870 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
7871 confusing ee/et name and made all extensions language/dialect
7872 rather than country reflecting. Changed example files to
7873 explicit reflect the ISO charset and added a few common
7874 ones to the example config [dirkx]
7876 *) Extend external module capability. To use this, you call
7877 configure with --with-module=path/to/mod1,path/to/mod2,etc.
7880 *) Backported the various "default charset" fixes from 1.3.12,
7881 including the AddDefaultCharset directive. [Jim Jagielski]
7883 *) Added the capability to do ${ENVVAR} constructs in the
7884 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
7885 it does this on a line by line basis; i.e. if the envvar
7886 expands to something with spaces you have to protect it
7887 by adding quotes around it (Unless of course you expect it
7888 to contains more than one argument. Alternatively you
7889 can compile it on a per token basis; which is what people
7890 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
7891 hampers fancier hacks.
7892 [Dirk-Willem van Gulik]
7894 *) Changed the 'ErrorDocument' syntax in that it NO longer
7895 supports the asymetric
7897 ErrorDocument 301 "Some message
7899 Note the opening " quote, without a closing quote. It now
7900 has either the following syntaxes
7902 ErrorDocument XXX /local/uri
7903 ErrorDocument XXX http://valid/url
7904 ErrorDocument XXX "Some Message"
7906 The recognition heuristic is: if it has a space it
7907 is a message. If it has no spaces and starts with a /
7908 or is a valid URL then treat it that way. Otherwise it
7909 is assumed to be a message.
7911 This breaks backward compatibility but makes live a hell
7912 of a lot easier for GUI's and config file parsers.
7913 [Dirk-Willem van Gulik]
7915 *) Changed 'CacheNegotiatedDocs' from its present/not-present
7916 syntax into a 'on' or 'off' syntax. As it currently is the
7917 only non nesting token which uses NO_ARGS and thus is an
7918 absolute pain for any config interface automation. This
7919 breaks backward compatibility. [Dirk-Willem van Gulik]
7921 *) Add ability to add external modules to the build process. This is
7922 done with --with-module=/path/to/module. Modules can only be added
7923 as static modules at this point.
7926 Changes with Apache 2.0a1
7928 *) Fix FreeBSD 3.3 core dump.
7929 Basically, ap_initialize() needs to get called before
7930 create_process(), since create_process() passes op_on structure
7931 to semop() to get a lock, but op_on isn't initialized until
7932 ap_initialize() calls setup_lock(). Here is a slight
7933 rearrangement to main() which calls ap_initialize() earlier...
7934 [Jeff Trawick <trawick us.ibm.com>]
7936 *) Enable Apache to use sendfile/TransmitFile API
7937 [Bill Stoddard, David Reid, Paul Reder]
7939 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
7943 *) Make file I/O and network I/O writev/sendv APIs consistent.
7944 Eliminate use of ap_iovec_t and use Posix struct iovec.
7945 Use seperate variable on ap_writev to set the number of iovecs
7946 passed in and number of bytes written.
7949 *) Adapt file iol to use APR functions. Replaced ap_open_file()
7950 with ap_create_file_iol(). ap_create_file_iol() requires that
7951 the file be opened prior to the call using ap_open().
7954 *) Port mod_include and mod_cgi to 2.0
7955 [Paul Reder, Bill Stoddard]
7957 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
7958 bytes_read/bytes_written is always valid (never -1). Plus
7959 some fixes to buff.c to correct problems introduced by the
7960 errno => ap_status_t changes a while back. Plus a fix to
7961 chunked encoding introduced right at the beginning of 2.0.
7964 *) Revamped UNIX build system to use autoconf and libtool.
7965 [Manoj Kasichainula, Sascha Schumann]
7967 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
7969 *) SECURITY: More rigorous checking of Host: headers to fix security
7970 problems with mass name-based virtual hosting (whether using mod_rewrite
7971 or mod_vhost_alias).
7972 [Ben Hyde, Tony Finch]
7974 *) Add back support for UseCanonicalName in <Directory> containers.
7975 [Manoj Kasichainula]
7977 *) Added APLOG_STARTUP log type. This allows us to write an error
7978 message without any of the date and time information. As a part
7979 of this change, I also removed all of the calls to fprintf(stderr
7980 and replaced them with calls to ap_log_error using APLOG_STARTUP
7981 writing to stderr is no longer portable, because we don't direct
7982 stderr to the error log on all platforms.
7985 *) Convert error logging functions to take errno as an argument.
7986 This makes our error logs more portable, because some Windows API's
7987 don't set errno. This change allows us to still output a valid
7988 message on all of our platforms.
7991 *) mod_mime_magic runs in 2.0-dev now.
7992 [Paul Reder <rederpj raleigh.ibm.com>]
7994 *) sendfile has been added to APR.
7995 [John Zedlewski <zedlwski Princeton.EDU>]
7997 *) buff.c has been converted to no longer use errno.
7998 [Manoj Kasichainula]
8000 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
8001 interface adaption to APR functions did it. [Martin Kraemer]
8003 *) Support DSOs properly on 32-bit HP-UX 11.0
8004 [Dilip Khandekar <dilip cup.hp.com>]
8006 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
8007 [Ralf S. Engelschall]
8009 *) Cleaned APR build environment integration and bootstrap APR
8010 automatically for developers from src/Configure.
8011 [Ralf S. Engelschall]
8013 *) Fixed building of src/support/htpasswd.c
8014 [Ralf S. Engelschall]
8016 *) When generating the Location: header, mod_speling forgot
8017 to escape the spelling-fixed uri. (Forw-Port from 1.3)
8020 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
8022 *) Change all pools to APR contexts. This is the first step to
8023 incorporating APR into Apache. [Ryan Bloom]
8025 *) Move "handler not found" warning message to below the check
8026 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
8027 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
8029 *) Support line-continuation feature in config.option file and
8030 allow the loading of multiple option sections at once via
8031 ``--with-option=<section1>,<section2>,...''
8032 [Ralf S. Engelschall]
8034 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
8036 Changes with Apache MPM
8038 *) Use asynchronous AcceptEx() and a completion port to accept and
8039 dispatch connections to threads in Windows NT/2000.
8042 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
8045 *) Implement the APACI --with-option facility
8046 (per default used the config.option file).
8047 [Ralf S. Engelschall]
8049 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
8051 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
8052 Replace pre_connection module call with a register_hook call and
8053 implement pre_connection as a hook. The intent is that these hooks will
8054 be extended to allow Apache to be multi-protocol, and also to allow the
8055 calling order to be specified on a per-hook/per-module basis.
8058 *) Implement mpm_* methods as "modules". Each method gets its own
8059 subdir in src/modules (eg: src/modules/prefork). Selection
8060 of method uses Rule MPM_METHOD. [Jim Jagielski]
8062 *) Port the hybrid server from the apache-apr repository as
8063 mpm_mpmt_pthread. [Manoj Kasichainula]
8065 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
8066 amongst the unix MPMs.
8068 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
8069 signal handling for the new world order. [Dean Gaudet]
8071 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
8072 of alloc.c for now. [Dean Gaudet]
8074 *) Handle partial large writes correctly. [Ben Laurie]
8076 *) Eliminate conn_rec's pointer to server. All it knows is the base server
8077 based on IP/port. [Ben Laurie]
8079 *) Port a bunch of modules to the new module structure.
8080 ["Michael H. Voase" <mvoase midcoast.com.au>]
8082 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
8084 *) Basic restructuring to introduce the MPM concept; includes various
8085 changes to the module API... better described by
8086 docs/initial_blurb.txt. [Dean Gaudet]
8088 Changes with Apache pthreads
8090 *) New buff option added: BO_TIMEOUT. It describes the timeout for
8091 buff operations (generally over a network).
8092 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
8094 *) Created http_accept abstraction. Added 4 new functions (not exported):
8095 init_accept(), begin_accepting_requests(), get_request(),
8096 stop_accepting_requests() [Bill Stoddard]
8098 *) Fix to ap_rprintf call that allows mod_info to work properly.
8099 [James Morris <jmorris intercode.com.au>]
8101 *) user and ap_auth_type fields were moved from connection_rec to
8102 request_rec. [Ryan Bloom]
8104 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
8105 needed in a threaded server.
8107 *) Initial pthread implementation from from Dean's apache-nspr code.
8108 [Bill Stoddard, Ryan Bloom]
8111 Changes with Apache 1.3.9
8113 *) Remove bogus error message when a redirect doesn't set Location.
8114 Instead, use an empty string to avoid coredump if the error message
8115 was supposed to include a location. [Roy Fielding]
8117 *) Don't allow configure to include mod_auth_digest unless it is
8118 explicitly requested, even if the user asked for all modules.
8121 *) Translate module names to dll names for OS/2 so that they are no more
8122 than 8 characters long and have an extension of "dll" instead of "so".
8125 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
8126 Fix test-compile check to check for randbyte instead of trand32.
8127 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
8128 and tweak to make Amaya happier. [Ronald Tschalär]
8130 *) Ensure that the installed expat include files are world readable,
8131 just like the other header files. [Martin Kraemer]
8133 *) Fixed generated AddModule adjustments in APACI's `configure' script
8134 in order to allow (new) modules like mod_vhost_alias to be handled
8135 correctly (which was touched by the adjustments for mod_alias).
8136 [Ralf S. Engelschall]
8138 *) For binary builds, add -R flag to apachectl to work around the lack of
8139 an absolute path to the ./libexec directory where the libhttp.ep file
8140 is needed for SHARED_CORE architectures. [Randy Terbush]
8142 *) WIN32: Create the CGI script process as DETACHED. This may solve the
8143 problem observed by some Win95/98 users where they get CGI script
8144 output sent to the console. [Bill Stoddard]
8146 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
8147 routines are now called ap_base64* and are 'plain' (i.e., no
8148 pool access or anything clever). Inside util.c the routines acting
8149 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
8150 The oddly named ap_uuencode(), ap_uudecode() are kept around for
8151 now but deprecated. [dirkx]
8153 *) Clean up the base64 and SHA1 additions and make sure they are
8154 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
8155 files. [Roy Fielding]
8157 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
8158 checking. Allow compiling on VS 6.0. [Randy Terbush]
8160 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
8162 *) Use TestCompile to search for the truerand library (rather than blindly
8163 assuming its existence). If it is not found, complain (but do not
8164 exit - yet). [Martin Kraemer]
8166 *) We forgot to add the new exported function names to
8167 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
8169 *) Add description of -T command-line option to usage().
8170 [Ralf S. Engelschall]
8172 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
8173 searched only AFTER libap has been searched, because libap needs
8174 some symbols from libos. [Martin Kraemer]
8176 *) Fix conflict with original mod_digest related to the symbol of the
8177 module dispatch list (which has to be unique for DSO and follow the
8178 usual conventions for the installation procedure).
8179 [Ralf S. Engelschall]
8181 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
8182 for other platforms as well. [Martin Kraemer]
8184 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
8185 types by AP_LONG and replace reference to renamed variable 'ubuf'
8186 by 'buffer'. [Martin Kraemer]
8188 Changes with Apache 1.3.8 [not released]
8190 *) Flush the output buffer immediately after sending an error or redirect
8191 response, since the result may be needed by the client to abort a
8192 long data transfer or restart a series of pipelined requests.
8193 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
8195 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
8196 [Ian Turner <iant sequent.com>] PR#4735
8198 *) Local struct mmap in http_core.c conflicted with system structure
8199 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
8201 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
8202 [Ronald Tschalär <ronald innovation.ch>]
8204 *) Fix a memory leak where the module counts were getting messed
8205 up across restarts. [David Harris <dharris drh.net>]
8207 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
8208 properly in mod_access.
8209 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
8211 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
8212 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
8214 *) PORT: Support for compaq/tandem/com.
8215 [Michael Ottati <michael.ottati compaq.com>, dirkx]
8217 *) Added SHA1 password encryption support to easy migration from
8218 Netscape servers. See support/SHA1 for more information.
8219 Caused the separation of ap_md5.c into md5, sha1 and a general
8220 ap_checkpass.c with just a validate_passwd routine. Added a
8221 couple of flags to support/htpasswd. Some reuse of the to64()
8222 function; hence renamed to ap_to64().
8223 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
8225 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
8226 with ASCII/EBCDIC conversions in "ident" query.
8227 [David McCreedy <McCreedy us.ibm.com>]
8229 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
8230 Change "Power Macintosh" to Power* so if uname prints "Power Book"
8231 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
8233 *) Fix SIGSEGV on some systems because the Vary fix below included
8234 a call to table_do with a variable argument list that was not
8235 NULL terminated. Replaced with better implementation. [Roy Fielding]
8237 Changes with Apache 1.3.7 [not released]
8239 *) The "Vary" response header field is now sanitised right before
8240 the header is sent back to the client. Multiple "Vary" fields
8241 are combined, and duplicate tokens (e.g., "Vary: host, host" or
8242 "Vary: host, negotiate, host, accept-language") are reduced to
8243 single instances. This is a better solution than the force-no-vary
8244 one (which is still valid for clients that can't cope with Vary
8245 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
8247 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
8249 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
8250 least on Linux and FreeBSD for now.
8253 *) Win32: More apache -k restart work. Restarts are now honored
8254 immediately and connections in the listen queue are -not- lost.
8255 This is made possible by the use of the WSADuplicateSocket()
8256 call. The listeners are opened in the parent, duplicated, then
8257 the duplicates are passed to the child. The original listen sockets
8258 are not closed by the parent across a restart, thus the listen queue
8260 [Bill Stoddard <stoddard raleigh.ibm.com>]
8262 *) Fix handling of case when a client has sent "Expect: 100-continue"
8263 and we are going to respond with an error, but get stuck waiting to
8264 discard the body in the pointless hope of preserving the connection.
8265 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
8267 *) Fix 'configure' to work correctly with SysV-based versions of
8268 'tr' (consistent with Configure's use as well). [Jim Jagielski]
8270 *) apxs: Add "-S var=val" option which allows for override of CFG_*
8271 built-in values. Add "-e" option which works like -i but doesn't
8272 install the DSO; useful for editing httpd.conf with apxs. Fix
8273 editing code so that multiple invocations of apxs -a will not
8274 create duplicate LoadModule/AddModule entries; apxs can now be
8275 used to re- enable/disable a module. [Wilfredo Sanchez]
8277 *) Win32: Update the server to use Winsock 2. Specifically, link with
8278 ws2_32.lib rather than wsock32.lib. This gives us access to
8279 WSADuplcateSocket() in addition to some other enhanced comm APIs.
8280 Win 95 users may need to update their TCP/IP stack to pick up
8281 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
8282 [Bill Stoddard <stoddard raleigh.ibm.com>]
8284 *) Win32: Redirect CGI script stderr (script debug info) into the
8285 error.log when CGI scripts fail. This makes Apache on Win32
8286 behave more like Unix.
8287 [Bill Stoddard <stoddard raleigh.ibm.com>]
8289 *) Fixed `httpd' usage display: -D was missing.
8290 [Ralf S. Engelschall] PR#4614
8292 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
8293 [Ralf S. Engelschall] PR#4561, PR#4562
8295 *) OS/2: Fix problem with accept lock semaphores where server would die with
8296 "OS2SEM: Error 105 getting accept lock. Exiting!"
8297 [Brian Havard] PR#4505
8299 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
8300 [Randy Terbush <randy covalent.net>]
8302 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
8303 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
8305 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
8306 command potentially _is_ GCC. [Ralf S. Engelschall]
8308 *) Fix apxs build issues on AIX
8309 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
8311 *) DocumentRoot Checking: Under previous versions, when Apache
8312 first started up, it used to do a stat of each DocumentRoot to
8313 see if it existed and was a directory. If not, then an error
8314 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
8315 does not exist, you will get error messages in error_log. If
8316 the '-t' command line option is used (to check the configuration)
8317 the check of DocumentRoot IS performed. An additional command
8318 line option, '-T', has been added if you want to avoid the
8319 DocumentRoot check even when checking the configuration.
8322 *) Win32: The query switch "apache -S" didn't exit after showing the
8323 vhost settings. That was inconsistent with the other query functions.
8324 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
8326 *) Win32: Changed behaviour of apache -k restart.
8327 Previously, the server would drain all connections in the stack's
8328 listen queue before honoring the restart. On a busy server, this
8329 could take hours. Now, a restart is honored almost immediately.
8330 All connections in Apache's queues are handled but connections in
8331 the stack's listen queue are discarded. Restart triggered by
8332 MaxRequestPerChild is unchanged.
8333 [Bill Stoddard <stoddard raleigh.ibm.com>]
8335 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
8336 the accept loop. Good for a 5% performance boost. Cleaned up
8337 parent/child process management code.
8338 [Bill Stoddard <stoddard raleigh.ibm.com>]
8340 *) Added ceiling on file size for memory mapped files.
8341 [John Giannandrea <jg meer.net>] PR#4122
8343 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
8344 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
8345 [Henri Gomez <gomez slib.fr>, Ralf S. Engelschall]
8347 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
8348 use this at least for Expat. [Ralf S. Engelschall]
8350 *) Allow .module files to specify libraries with Lib:.
8353 *) Allow SetEnvIf[NoCase] to test environment variables as well
8354 as header fields and request attributes. [Ken Coar]
8356 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
8357 content-types are "text/html;parameters". PR#4524 [Ken Coar]
8359 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
8360 never accepted into any standard, and it opens up certain DoS
8361 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
8363 *) TestCompile updated. We can now run programs and output the
8364 results during the Configure process. [ Jim Jagielski]
8366 *) The source is now quad (long long) aware as needed. Specifically,
8367 the Configure process determines the correct size of off_t and
8368 *void. When the OS/platform/compiler supports quads, ap_snprintf()
8369 provides for the 'q' format qualifier (if quads are not available,
8370 'q' is silently "demoted" to long). [Jim Jagielski]
8372 *) When the username or password fed to htpasswd is too long, include the
8373 size limit in the error message. Also report illegal characters
8374 (currently only ':') in the username. Add the size restrictions
8375 to the man page. [Ken Coar]
8377 *) Fixed the configure --without-support option so it doesn't result in
8378 an infinite loop. [Marc Slemko]
8380 *) Piped error logs could cause a segfault if an error occured
8381 during configuration after a restart.
8382 [Aidan Cully <aidan panix.com>] PR#4456
8384 *) If a "Location" field was stored in r->err_headers_out rather
8385 than r->headers_out, redirect processing wouldn't find it and
8386 the server would core dump on ap_escape_html(NULL). Check both
8387 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
8388 if Location isn't set. [Doug MacEachern, Ken Coar]
8390 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
8391 of the Expat 1.0.2 distribution. [Greg Stein]
8393 *) Replace regexec() calls with calls to a new API stub function
8394 ap_regexec(). This solves problems with DSO modules which use the regex
8395 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]
8397 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
8398 environment variables can be set according to the protocol version
8399 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
8401 *) Add DSO support for OpenStep (Mach 4.2) platform.
8402 [Ralf S. Engelschall, Rex Dieter <rdieter math.unl.edu>] PR#3997
8404 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
8405 [Jan Gallo <gallo pvt.sk>] PR#3690, PR#4373
8407 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
8408 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
8410 *) Better DSO flags recognition on NetBSD platforms using ELF.
8411 [Todd Vierling <tv pobox.com>] PR#4310
8413 *) Always log months in english format for %t in mod_log_config.
8414 [Petr Lampa <lampa fee.vutbr.cz>] PR#4366, 679
8416 *) Support for server-parsed and multiview-determined ReadmeName and
8417 HeaderName files in mod_autoindex. Removed the restriction on
8418 "/"s in ReadmeName and HeaderName directives since the *sub_req*
8419 routines will deal with the access issues. (It's now possible to
8420 have {site|group|project|customer|...} wide readmes and headers.)
8421 [Raymond S Brand <rsbx rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
8424 *) When stat() fails, don't assume anything about the contents of
8425 the struct stat. [Ed Korthof <ed bitmechanic.com>]
8427 *) It's OK for a semop to return EINTR, just loop around and try
8428 again. [Dean Gaudet]
8430 *) Fix configuration engine re-entrant hangups, which solve a
8431 handful of problems seen with mod_perl <Perl> configuration sections
8432 [Salvador Ortiz Garcia <sog msg.com.mx>]
8434 *) Mac OS and Mac OS X Server now use the appropriate custom layout
8435 by default when building with APACI; allow for platform-specific
8436 variable defaults in configure. [Wilfredo Sanchez]
8438 *) Do setgid() before initgroups() in http_main; some platforms
8439 zap the grouplist when setgid() is called. This was fixed in
8440 suexec earlier, but the main httpd code missed the change.
8441 [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2579
8443 *) Add recognition of .tgz as a gzipped tarchive.
8444 [Bertrand de Singly <bertrand.de-singly polytechnique.fr>] PR#2364
8446 *) mod_include's fsize/flastmod should allow only relative paths, just
8447 like "include file". [Jaroslav Benkovsky <benkovsk pha.pvt.cz>]
8449 *) OS/2: Add support for building loadable modules using DLLs.
8452 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
8455 *) Fix minor but annoying bug with the test for Configuration.tmpl
8456 being newer than Configuration so that it is less likely to fail
8457 when using APACI and shadow sources. [Wilfredo Sanchez]
8459 *) PORT: Add initial support for Mac OS (versions 10.0 and
8460 greater). Use Mac OS X Server layout for now. Clean up dyld code
8461 in unix/os.c, and don't install the dyld error handlers, which
8462 are no longer needed in Mac OS. [Wilfredo Sanchez]
8464 *) Rename Rhapsody layout to "Mac OS X Server". Change install
8465 locations to appropriate ones for user-built (as opposed to
8466 system) installs. [Wilfredo Sanchez]
8468 *) Modify mod_autoindex's handling of AddDescription so that the
8469 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
8471 *) Add functionality to the install-bindist.sh script created by
8472 binbuild.sh to use tar when copying distribution files to the
8473 serverroot. This allows upgrading an existing installation
8474 without nesting the new distribution in the old.
8476 install-bindist.sh now detects the local perl5 path to install
8477 apxs and dbmmanage with proper path to perl interpreter.
8479 Add an install-binsupport target which copies the source files
8480 for apxs and dbmmanage to bindist to allow these scripts to
8481 be properly installed relative to the destination serverroot.

8509 value of the DirectoryIndex directive is a single dot. Also likely
8510 to happen for anyother values of DirectoryIndex that will map back

8594 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
8597 *) Correct an apparent typo: on the Windows and MPE platforms, the
8598 htpasswd utility was limiting passwords to only 8 characters.
8601 *) EBCDIC platforms: David submitted patches for two bugs in the
8602 MD5 digest port for EBCDIC machines:
8603 a) the htdigest utility overwrote the old contents of the digest file
8604 b) the Content-MD5 header value (ContentDigest directive) was wrong
8605 when the returned file was not converted from EBCDIC, but was a
8606 binary (e.g., image file) in the first place.
8607 [David McCreedy <mccreedy us.ibm.com>]
8609 *) support/htpasswd now permits the password to be specified on the
8610 command line with the '-b' switch. This is useful when passwords
8611 need to be maintained by scripts -- particularly in the Win32
8612 environment. [Ken Coar]
8614 *) Win32: Win32 multiple services patch. Added capability to install and
8615 run multiple copies of apache as individual services.
8618 apache -n apache1 -i -f c:/httpd.conf
8619 Installs apache as service 'apache1' and associates c:/httpd.conf
8622 Starts apache1 service.
8624 Stops apache1 service
8627 apache -n apache2 -i
8628 Installs apache as service 'apache2'. httpd.conf is located under
8629 the default server root (/apache/conf/httpd.conf).
8631 Starts apache2 service.
8634 apache -n apache3 -i -d c:/program files/apache
8635 Install apache as service 'apache3' and sets server root to
8636 c:/program files/apache.

8645 mismatches were causing compilation problems with gcc -pedantic and
8646 in the TPF cross-compilation. [Ken Coar]
8648 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
8649 a roughly 5 fold speed up. [Brian Havard]
8651 *) proxy ftp: instead of using the hardwired string "text/plain" as
8652 a fallback type for files served by the ftp proxy, use the
8653 ap_default_type() function to determine the configured type.
8654 This allows for special configurations like
8655 <Directory proxy:ftp://some.host>
8656 DefaultType gargle/blurb
8658 Additionally, add the Content-Encoding: header to FTP proxy replies
8659 when the encoding is defined (by the AddEncoding directive).
8660 Because it was missing, it was almost impossible to browse compressed
8661 files using the FTP proxy (works now perfectly in Communicator).
8662 The ftp proxy now also returns the Date: and Server: header lines (if not
8663 much else... This code is "somewhat" broken) like normal requests do.
8666 *) Be more smart in APACI's configure script when determining the UID/GID
8667 for User/Group directives and use the determined UID/GID to initialize
8668 the permissions on the proxycachedir.
8669 [Dirk-Willem van Gulik, Ralf S. Engelschall]
8671 *) Changed the forking-prior-to-cleanup in the proxy module to first
8672 check wether it actually needs to collect garbage. This reduces
8673 the number of fork()s from one/request to just the odd one an hour.
8674 [Dirk-Willem van Gulik]

8701 Changes with Apache 1.3.5 [not released]
8703 *) M_INVALID needed a value within the scope of METHODS so that unknown
8704 methods can be access controlled. [Roy Fielding] PR#3821
8706 *) Added PassAllEnv; makes server's entire environment available
8707 to CGIs and SSIs executed within directive's scope. [Ken Coar]
8709 *) ap_uuencode() always added two trailing '='s and encoding of
8710 8 bit characters on a machine with signed char may produced
8711 incorrect results. Additionally ap_uuencode() should now
8712 work correctly on EBCDIC platforms.
8713 [Ronald Tschalär <ronald innovation.ch>] PR#3411
8715 *) WIN32: Binary installer now runs the configuration DLL before
8716 the reboot prompt (which is only given if MSVCRT.DLL system
8717 DLL is new or updated). This should avoid the configuration
8718 directory being empty after installation. [Paul Sutton]
8719 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

8723 the Apache service on NT. [Paul Sutton] PR#3741
8725 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
8727 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
8728 have been reported with flock() locking (probably related to kernel
8729 version). [Dean Gaudet] PR#2723, 3531

8742 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
8743 for 8-bit safeness. [Dean Gaudet]
8745 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
8746 because SPARCs have a small machine-specific maximum size for the Global
8747 Offset Table which is often exceeded when compiling one of the larger
8748 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977
8750 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

8767 *) Let APACI's configure script correctly complain for unknown --enable-XXX
8768 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
8770 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
8771 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
8772 possible buffer overflows. [Ralf S. Engelschall]
8774 *) Remove no longer used non-API function ap_single_module_init().

8777 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
8780 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
8781 to make platform installations easier. [Wilfredo Sanchez]
8783 *) In configure, do not append the target name to the directory path if
8784 the path already contains "apache". [Ralf S. Engelschall]
8786 *) SIGPIPE is now ignored by the server core. The request write routines
8787 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
8788 correctly check for output errors and mark the connection as aborted.
8789 Replaced many direct (unchecked) calls to ap_b* routines with the
8790 analogous ap_r* calls. [Roy Fielding]
8792 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
8793 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
8794 Furthermore map lookups for non-existent keys are now cached as well.
8795 Additionally "txt" maps are now parsed with simple string functions
8796 instead of using ap_pregcomp(). As a side effect a bug that prevented
8797 the usage of keys containing the "," character was fixed.
8798 The changes drastically improve the performance when large rewrite maps
8800 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
8802 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
8803 other than GET, and const'd the definition of method in request_rec.
8806 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
8808 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
8809 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
8811 *) Add %V to mod_log_config, this logs the hostname according to the
8812 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
8813 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
8815 *) Add support for \n and \t to mod_log_config, can be used to produce
8816 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
8818 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
8820 *) Added informative error messages for failed munmap() and fseek() calls

8823 *) Added some informative error messages for some failed malloc()
8824 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
8826 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
8827 is removed. This allows <Directory proxy:*> directives to work and
8828 prevents invalid requests from killing the process.
8829 [Brian Havard <brianh kheldar.apana.org.au>]
8831 *) Reorganised FAQ document.
8832 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497

8835 David N. Welton: you can now have it generate an HTML TABLE, presumably
8836 for integration into other HTML sources. David updated the ab man page
8837 as well and added some missing descriptions. Thanks!

8840 *) Win32: The filename validity checker now allows filenames containing
8841 characters in the range 0x80 to 0xff (for example accented characters).
8842 [Paul Sutton] PR#3890
8844 *) Added conditional logging based upon environment variables to
8845 mod_log_config. mod_log_referer and mod_log_agent
8846 are now deprecated. [Ken Coar]
8848 *) Allow apache acting as a proxy server to relay the real
8849 reason of a failure to a client rather than the "internal
8850 server error" it does currently. The general exposure mechanism
8851 can be triggered by any module by setting the "verbose-error-to"
8852 note to "*"; this allows more than just proxy errors to be exposed.
8853 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
8855 *) Moved man pages for ab and apachectrl to section 8.
8856 [Wilfredo Sanchez, Roy Fielding]
8858 *) Added -S option to install.sh so that options can be passed to
8859 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
8861 *) Tweak modules Makefile generated by Configure so that it handles
8862 the test case of no modules being selected. [<chaz reliant.com>]
8864 *) Added a <LimitExcept method ...> sectioning directive that allows
8865 the user to assign authentication control to any HTTP method that
8866 is *not* given in the argument list; i.e., the logical negation
8867 of the <Limit> directive. This is particularly useful for controlling
8868 access on methods unknown to the Apache core, but perhaps known by
8869 some module or CGI script. [Roy Fielding, Tony Finch]
8871 *) Prevent apachectl from complaining if the PIDFILE exists but
8872 does not contain a process id, as might occur if the server is
8873 being rapidly restarted. [Wilfredo Sanchez]
8875 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
8877 *) Entity tag comparisons for If-Match and If-None-Match were not being
8878 performed correctly -- weak tags might cause false positives. Also,
8879 strong comparison wasn't properly enforced in all cases.
8880 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657

8885 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
8886 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
8888 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
8889 to util.c for parsing an HTTP header field value to extract the next
8890 list item, taking into account the possible presence of nested comments,
8891 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
8892 insignificant whitespace and lowercases non-quoted tokens.
8893 [Roy Fielding] PR#2065
8895 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
8896 code different from 500. This allows the proxy to, e.g., return
8897 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
8899 *) Fix ordering of language variants for the case where the traditional
8900 negotiation algorithm is being used with multiple language variants
8901 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
8903 *) Do not round the TCN quality calculation to 5 decimal places,
8904 unlike RFC 2296, because the calculation might need 12 decimal places
8905 to get the right result. [Roy Fielding]
8907 *) Remove unused code to disable transparent negotiation when
8908 negotiating on encoding only, as we now handle encoding too
8909 (though this is nonstandard for TCN), remove charset=ISO-8859-1
8910 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
8911 some debugging statements within mod_negotiation. [Koen Holtman]
8913 *) Fixed a rare memory corruption possibility in mod_dir if the index
8914 file is negotiable and no acceptable variant can be found.
8915 [Dean Gaudet, Roy Fielding, Martin Kraemer]
8917 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
8918 searching the Win32 registry for script interpreters.
8921 *) Win32: The compiled-in default filename for the error log is now
8922 error.log, which matches the default in the distributed httpd.conf.
8925 *) Win32: Any error messages from -i or -u command line options are now
8926 displayed on the console output rather than sent to the error log.
8927 Also the "Running Apache..." message is not output unless Apache is
8928 going to serve requests. [Paul Sutton]
8930 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
8931 and use a private significator ('$apr1$') to mark passwords as
8932 being smashed with our own algorithm. Also abstract the password
8933 checking into a new ap_validate_password() routine. [Ken Coar]
8935 *) Win32: The filename validity checker now allows "COM" but refuses
8936 access to "COM1" through "COM4". This allows filenames such
8937 as "com.name" to be served. [Paul Sutton] PR#3769.
8939 *) BS2000: Adapt to the new ufork() system call interface which will
8940 make subtasking easier on the OSD/POSIX mainframe environment.
8943 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to

8972 sides with double quotes and prepending 'x'). 'x' was chosen
8973 because it's more universal and hopefully easier for old shell
8974 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
8977 *) The status module now prints out both the main server generation as
8978 well as the generation of each process. Also, the vhost info is
8979 printed with '?notable'. [Jim Jagielski]
8981 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
8982 and this makes its functions available to things in src/support.
8985 Changes with Apache 1.3.4
8987 *) Renamed macros status_drops_connection to ap_status_drops_connection
8988 and vestigial scan_script_header to ap_scan_script_header_err,
8989 mostly for aesthetic reasons. [Roy Fielding]
8991 *) The query switch "httpd -S" didn't exit after showing the
8992 vhost settings. That was inconsistent with the other query functions.
8995 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
8996 filename to the end of the STANDARD_MODULE_STUFF. Its
8997 presence at the beginning prevented reporting of the filename
8998 for modules compiled before 1 January 1999. [Ken Coar]
9000 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
9001 to detect and prevent access to special DOS device file names.
9002 [Paul Sutton, Ken Parzygnat]
9004 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
9005 and Makefile_win32_debug.txt (debug build) that work on Win95.
9006 Run each of the following from the src directory:
9007 nmake /f Makefile_win32.txt # compiles normal build
9008 nmake /f Makefile_win32.txt install # compiles and installs
9009 nmake /f Makefile_win32.txt clean # removes compiled junk
9010 nmake /f Makefile_win32_debug.txt # compiles debug build
9011 nmake /f Makefile_win32_debug.txt install
9012 nmake /f Makefile_win32_debug.txt clean
9015 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
9016 to build binary distributions. [Lars Eilebrecht]
9018 *) IndexOptions SuppressColumnSorting only turned off making
9019 the column headers anchors; you could still change the display
9020 order by manually adding a '?N=A' or similar query string to the
9021 URL. Now SuppressColumnSorting locks in the sort order so
9022 it can't be overridden this way. [Ken Coar]
9024 *) Added IndexOrderDefault directive to supply a default sort order
9025 for FancyIndexed directory listings. [Ken Coar] PR#1699
9027 *) Change the ap_assert macro to a variant that works on all platforms.
9028 [Richard Prinz <richard.prinz cso.net>] PR#2575
9030 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
9031 search for an underscore on dlsym() (as it's already the case
9032 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
9034 *) Small fix for mod_env.html: The module was documented as to be _not_
9035 compiled into Apache per default, although it _IS_ compiled into
9036 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
9038 *) Instead of fixing a bug in the generation procedure for config.status (a
9039 backslash was missing) we remove the bug together with it's complete
9040 context because the special cases of the past can now no longer occur
9041 because of the recent magic for the --with-layout default.
9042 [Ralf S. Engelschall] PR#3590
9044 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
9045 making sure the src/support/ tools are _forced_ to be build last (they
9046 depend on other libraries).
9047 [Markus Theissinger <markus.theissinger gmx.de>]
9049 *) Fix installation procedure: Now that os-inline.c is actually used (a
9050 recently fixed bug prevented this) we need to also install os-include.c
9051 in addition to os.h into the PREFIX/include/ location or building of
9052 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
9054 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
9055 allow us to distinguish between a garbled DSO (or even a file which isn't
9056 an Apache module DSO at all) and a DSO which doesn't match the current
9057 Apache API. [Ralf S. Engelschall] PR#3152
9059 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
9060 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
9061 match case insensitive (this especially avoids nasty patterns like
9062 `[tT][eE][sS][tT]'). Second two additional internal map functions
9063 `escape' and `unescape' were added which can be used to escape/unescape
9064 to/from hex-encodings in URLs parts (this is especially useful in
9065 combination with map lookups).
9066 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
9068 *) Renamed the macro escape_uri() to ap_escape_uri() which was
9069 forgotten (because it was a macro) in the symbol renaming process.
9070 [Ralf S. Engelschall]
9072 *) Fix some inconsistencies related to the scopes of directives. The only
9073 user visible change is that the directives `UseCanonicalName' and
9074 `ContentDigest' now use the (more correct) `Options' scope instead of
9075 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
9077 *) Using DSO, the Server token was being mangled. Specifically, the
9078 module's token was being added first before the Apache token. This
9079 has been fixed. [Jim Jagielski]
9081 *) Major overhaul of mod_negotiation.c, part 2.
9082 - properly handle "identity" within Accept-Encoding.
9083 - allow encoded variants in RVSA negotiation and let them appear in
9084 the Alternates field using the non-standard "encoding" tag-list.
9085 - fixed both negotiation algorithms so that an explicitly accepted
9086 encoding is preferred over no encoding if "identity" is not
9087 included within Accept-Encoding.
9088 - added ap_array_pstrcat() to alloc.c for efficient concatenation
9089 of large substring sequences.
9090 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
9093 *) Major overhaul of mod_negotiation.c, part 1.
9094 - cleanups to mod_negotiation comments and code structure
9095 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
9096 support for everything in the upcoming HTTP/1.1
9097 revision (draft-ietf-http-v11-spec-rev-06.txt).
9098 - language tag matching also handles tags with more than 2
9100 - empty Accept, Accept-Language, Accept-Charset headers are
9101 processed correctly; previously an empty header would make all
9102 values acceptable instead of unacceptable.
9103 - allowed for q values in Accept-Encoding
9104 - added support for transparent content negotiation (rfc2295 and
9105 rfc2296) (though we do not implement all features in these drafts,
9106 e.g. no feature negotiation). Removed old experimental version.
9107 - implemented 'structured entity tags' for better cache correctness
9108 (structured entity tags ensure that caches which can deal with Vary
9109 will (eventually) be updated if the set of variants on the server
9111 - this involved adding a vlist_validator element to request_rec
9112 - this involved adding the ap_make_etag() function to the global API
9113 - modified guessing of charsets used by Apache negotiation algorithm
9114 to guess 'no charset' if the variant is not a text/* type
9115 - added code to sort multiviews variants into a canonical order so that
9116 negotiation results are consistent across backup/restores and mirrors
9117 - removed possibility of a type map file resolving to another type map
9118 file as its best variant
9119 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
9121 *) RFC2396 allows the syntax http://host:/path (with no port number)
9122 but the proxy disallowed it (ap_proxy_canon_netloc()).
9123 [David Kristol <dmk bell-labs.com>] PR#3530
9125 *) When modules update/modify the file name in the configfile_t structure,
9126 syntax errors will report the updated name, not the original one.
9127 [Fabien Coelho <coelho cri.ensmp.fr>] PR#3573
9129 *) Correct some filename case assumptions from WIN32 to
9130 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh kheldar.apana.org.au>]
9132 *) For %v log ServerName regardless of the UseCanonicalName
9133 setting (similarly for %p). [Dean Gaudet]
9135 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
9136 rather late (too late for some invocations of TestCompile).
9137 This improves the make environment available to TestCompile and
9138 the *.module scripts. [Martin Kraemer]
9140 *) The hashbang emulation code in ap_execve.c would interpret
9141 #!/hashbang/scripts correctly, but failed to fall back to a
9142 standard shell for scripts which did NOT start with #!
9143 Now SHELL_PATH is started in these cases. [Martin Kraemer]
9145 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
9148 *) Update APXS manual page: some -q option arguments were missing
9149 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
9151 *) Cleanup the command line options: `-?' was documented to show
9152 the usage list but does it with an error because `?' is not a valid
9153 command. OTOH a lot of users expect `-h' to print such a usage list and
9154 instead are annoyed for ages by our huge unreadable list of directives.
9155 So we now changed the command line options this way:
9157 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
9158 very similar to the popular linker option.
9160 Intent: while -l gives the small list of modules, -L now gives the
9161 large list of directives implemented by these modules. This is also
9162 consistent with -v (short version info) and -V (large version info).
9164 Intent: it's now the expected option ;-)
9165 The manual page was adjusted accordingly.
9166 [Ralf S. Engelschall] PR#2714
9168 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
9169 wasn't defined. [Rick Franchuk <rickf transpect.net>]
9171 *) Removed recently introduced bugs and disfigurements in APACI:
9172 o fixed argument line processing: using $args was broken: It was not
9173 initialized and using args="$args $apc_option" and even args="$args
9174 \"$apc_option\"" fails in the second processing round for any arguments
9175 containing whitespaces. The only correct way is to use the construct
9176 "$@" (but not possible here) or iterate _both_ times over the implicit
9177 argument line (no argument to for-loop) which is what we now use.
9178 o make --with-layout=Apache the default without creating
9179 redundancy (copying the --with-layout block in the argument parsing
9180 loop). We achieve this by using the "$@" construct together with the
9181 `set' command to prepend --with-layout=Apache to the command line in
9182 case --with-layout is not used.
9183 o fixed auto-suffix handling now that config.layout exists.
9184 Paths which are auto-suffixed are marked with a trailing plus sign in
9185 config.layout and every path now can be marked this way (not only the
9186 four paths for which we do it currently). Additionally the suffix is
9187 no longer a static one. Instead it's now `/<target>' where <target> is
9188 the argument of the --target option or per default `httpd'.
9189 o allow also tabs (and only spaces) where we match whitespaces
9190 o various fixes and cleanups related to used shell coding style
9191 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
9192 o trimmed output of --help to fit into 80 columns
9193 [Ralf S. Engelschall]
9195 *) Added two new core API functions, ap_single_module_configure() and
9196 ap_single_module_init(), which are now used by mod_so to configure a module
9197 after loading. [Ralf S. Engelschall]
9199 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
9200 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
9201 of ap_config.h to allow serialized accept for multiport listens.
9202 [Roy Fielding, Curt Sampson] PR#3120
9204 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
9205 of ap_config.h that would skip several defines if DEFAULT_GROUP
9206 was overridden. [Roy Fielding]
9208 *) PORT: The I86 version of DGUX has support for strncasecmp and
9209 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
9211 *) Fix ordering of definitions in ap_config.h so that ap_inline is
9212 defined before it might be used. [Victor Khimenko]
9214 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
9215 [Tom Serkowski <tks bsdi.com>] PR#3453
9217 *) Make generation of src/Configuration.apaci more robust: It failed to
9218 differenciate between modules when one module name was a postfix of
9219 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
9220 just XXX (think about totally non-standard names like "apache_ssl", too).
9221 [Ralf S. Engelschall] PR#3380
9223 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
9224 since 1.3b7) and make whitespace handling more robust (it failed horrible
9225 when whitespaces were present in the arguments of -D options).
9226 [Ralf S. Engelschall] PR#3240
9228 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
9229 creates an external package shadow tree in DIR before the local build
9230 shadow tree is generated under DIR. This way one can have the extracted
9231 Apache distribution tree read-only on NFS or CDROM and still build Apache
9232 from these sources. An automatically triggered VPATH-like mechanism is
9233 provided through the TOP variable, too.
9234 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez apple.com>]
9236 *) Fix negotiation so that a Vary response header is correctly
9237 generated when, for a particular dimension, variants only vary
9238 in having or not having a value for that dimension. [Paul Sutton]
9240 *) Fix negotiation so that we prefer an encoded variant over an
9241 unencoded variant if the user-agent explicitly says it can
9242 accept that encoding. Previously we always preferred the unencoded
9244 [Paul Ausbeck <paula alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
9246 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
9247 and the usage page was inconsistent with the functionality and manpage.
9248 [Ralf S. Engelschall]
9250 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
9251 They can occur multiple times and their arguments (`xxx') are passed AS
9252 IS to the compiler/linker command. [Ralf S. Engelschall]
9254 *) Fixed possible (but harmless in practice) bug in the DBM lookup
9255 procedure of mod_rewrite: very long keys were truncated.
9256 [Ralf S. Engelschall]
9258 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
9259 identifier, currently "Apache" and "GNU" are pre-defined in the file
9260 config.layout. Custom layouts are possible by using FILE:ID as the
9261 argument where the layout ID is taken from FILE.
9263 The config.layout file consists of <Layout ID>..</Layout> sections
9264 where inside those sections "path_variable: path_value" pairs can be
9265 specified. These lines are converted to path_variable='path_value'.
9267 *) Add a DefaultLanguage directive so that files missing a language
9268 extension (e.g., .fr, .de) can be labelled as being some other
9269 default language. DefaultLanguage can appear in <Directory> and
9270 <Files> containers as well as .htaccess files. [Paul Sutton]
9273 *) Fix TARGET configuration when configuring and installing using
9274 APACI configure. TARGET now defines the basename of the configuration
9275 file, startup script, manual page, etc. log_error_core() now reports
9276 the server binary name given by argv[0]. TARGET can now also be defined
9277 with --target=TARGET parameter passed to APACI configure.
9278 [Ralf Engelschall, Randy Terbush]
9280 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
9281 rather than OPT_INCLUDES [Rainer Schoepf <schoepf uni-mainz.de>]
9283 *) ap_md5_binary() was using sprintf() rather than a table lookup
9284 to convert binary bytes to hex digits.
9285 [Ronald Tschalär <ronald innovation.ch>] PR#3409
9287 *) Fix SEGV in TCN negotiation if no variants are acceptable.
9288 [Martin Plechsmid <plechsmi karlin.mff.cuni.cz>] PR#1987
9290 *) API: ap_exists_config_define() function is now "public" [Doug MacEachern]
9292 *) Fix documentation of `Action' directive: It can activate a CGI script
9293 when either a handler or a MIME content type is triggered by the request.
9294 [Andrew Pimlott <pimlott math.harvard.edu>] PR#3340
9296 *) Document the `add' command of `dbmmanage' in `dbmmanage.1' manpage.
9297 [David MacKenzie <djm uu.net>] PR#3394
9299 *) Ignore a "ErrorDocument 401" directive with a full URL and write a
9300 notice to the error log. It is not possible to send a 401 response
9301 and a redirect at the same time. [Lars Eilebrecht]
9303 *) Fallback to native compilers for IRIX-32 platform. It seems that
9304 a gcc 2.8.1 compiled apache is logging client addresses with all
9305 bits set (255.255.255.255). This is the second such problem caused
9306 by gcc 2.8.1 compiler. The first being broken semaphore locking.
9309 *) Updated mime.types to reflect current Internet media types
9310 and include a URL to the registry.
9311 [Manoj Kasichainula, Roy Fielding] PR#2380, 2286, 2246
9313 *) SECURITY: Do a more complete check in mod_include to avoid
9314 an infinite loop of recursive SSI includes. [Marc Slemko] PR#3323
9316 *) Add APACI --suexec-docroot and --suexec-logfile options which can be
9317 used to set the document root directory (DOC_ROOT) and the suexec
9318 logfile (LOG_EXEC), respectively. Additionally the --layout option
9319 was changed to show more information about the suEXEC setup.
9320 [Lars Eilebrecht] PR#3316, 3357, 3361
9322 *) Added the last two WebDAV status codes of 424 (Failed Dependency)
9323 and 507 (Insufficient Storage) for use by third-party modules.
9326 *) Enabled all of the WebDAV method names for use by third-party
9327 modules, Limit, and Script directives. That includes PATCH,
9328 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
9329 Improved mod_actions.c so that it can use any of the methods
9330 defined in httpd.h. Added ap_method_number_of(method) for
9331 getting the internal method number. [Roy Fielding]

9357 since it often includes file path info. Enable sending of error-notes
9358 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
9360 *) http_config.c would respond with 501 (Method Not Implemented) if a
9361 content type handler was specified but could not be found, which
9362 should have been a 500 response. Likewise, mod_proxy.c would responsd

9380 further future enhancements). [Harrie Hazewinkel
9381 <harrie.hazewinkel jrc.it>]
9383 *) Add APACI --permute-module=foo:bar option which can be used to
9384 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
9385 in the Configuration[.apaci] file. Two special and important variants are
9386 supported for the option argument: first BEGIN:foo which permutes module
9387 mod_foo with the begin of the module list, i.e. it `moves' the module to
9388 the begin of the list (gives it lowest priority). And second foo:END
9389 which permutes mod_foo with the end of the module list, i.e. it `moves'
9390 the module to the end of the list (gives it highest priority).

9447 [Wilfredo Sanchez <wsanchez apple.com>]
9449 *) Fix inheritance of IndexOptions NameWidth and remove unintended
9450 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
9452 *) Fix per-directory config merging for cases in which a 500 error
9453 is encountered in an .htaccess file somewhere down the tree.
9456 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
9458 *) Fixed a segmentation violation in mod_proxy when a response is
9459 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
9461 Changes with Apache 1.3.3
9463 *) Added a complete implementation of the Expect header field as
9464 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
9465 response when we already know the final status, which is mighty
9466 useful for PUT responses that result in 302 or 401. [Roy Fielding]
9468 *) Remove extra trailing whitespace from the getline results as part
9469 of the protocol processing, which is extra nice because it works
9470 between continuation lines, is almost no cost in the normal case
9471 of no extra whitespace, and saves memory. [Roy Fielding]
9473 *) Added new HTTP status codes and default response bodies from the
9474 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
9475 HTTP Extension Framework (510) specifications. Did not add the
9476 WebDAV 424 and 425 codes because they are bogus. We don't use any
9477 of these codes yet, but they are now available to 3rd-party modules.
9480 *) Fix a possible race condition between timed-out requests and the
9481 ap_bhalfduplex select that might result in an infinite loop on
9482 platforms that do not validate the descriptor. [Roy Fielding]
9484 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
9485 running Apache server [Paul Sutton]

9488 of "-". [Martin Plechsmid <plechsmi karlin.mff.cuni.cz>, Marc Slemko]

9498 [M. Laak <maert proinv.ee>] PR#3108

9501 calculation in mod_status for all systems which don't have POSIX
9502 sysconf() (like UTS 2.1) and not only for the NEXT platform.
9503 [Dave Dykstra <dwd bell-labs.com>] PR#3055
9505 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
9506 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
9507 instead of ap_getword(..., ' ') (which parses only according to spaces
9508 but not tabs). [James Morris <jmorris intercode.com.au>,

9539 absolute paths begin with "/" -- because they don't on Win32.
9540 [Ken Parzygnat <kparz raleigh.ibm.com>] PR#2976, 3074

9552 *) Reconstructed the loop through multiple htaccess file names so
9553 that missing files are not confused with unreadable files.
9556 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
9557 errno on an error, which leads to one error being mistaken for
9558 another when reading non-existent .htaccess files.

9574 [Elf Sternberg <elf halcyon.com>]
9576 *) Avoid possible line overflow in Configure: Use an awkfile to
9577 handle the creation of modules.c [Jim Jagielski]
9579 Changes with Apache 1.3.2
9581 *) Fix bug in ap_remove_module(), which caused problems for dso's
9582 who were the top_module. [Doug MacEachern]
9584 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
9585 mod_auth_db to both be friendly to users who wants to use this version
9586 and to avoid problems under platforms where only version 2.x is present.
9587 [Dan Jacobowitz <drow false.org>, Ralf S. Engelschall]
9589 *) When using ap_log_rerror(), make the error message available to the
9590 *ERROR_NOTES envariables by default. [Ken Coar]
9592 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
9593 You now must define a BS2000Account name for the server User.
9594 This has fewer security implications than the old approach.
9597 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
9598 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
9599 platform to make the braindead HPUX linker happy. Notice, for the module
9600 DSOs we don't have to use this, because these are loaded manually (and
9601 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
9603 *) Remove 64 thread limit on Win32.
9604 [Bill Stoddard <stoddard raleigh.ibm.com>]
9606 *) Remove redundant substitutions in top-level Makefile.tmpl.
9607 [Ralf S. Engelschall]
9609 *) Fix APACI's `Group' configuration adjustment - especially for Linux
9610 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
9612 *) Make PrintPath work generically instead of having one version
9613 strictly for OS/2. [Jim Jagielski, Brian Havard]
9615 *) Fix the recently introduced C header file checking: We now use the C
9616 pre-processor pass only (and no longer the complete compiler pass) to
9617 determine whether a C header file exists or not. Because only this way
9618 we're safe against inter-header dependencies (which caused horrible
9619 portability problems). The only drawback is that we now have a CPP
9620 configuration variable which has to be determined first (we do a similar
9621 approach as GNU Autoconf does here). When all fails the user still has
9622 the possibility to override it manually via APACI or src/Configuration.
9623 As a fallback for the header check itself we can directly check the
9624 existance of the file under /usr/include, too.
9625 [Ralf S. Engelschall] PR#2777
9627 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
9628 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
9629 ap_private_extern defined to hide symbols that conflict with loaded
9630 dynamic libraries on the NEXT and RHAPSODY platforms.

9652 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
9653 trailing slash problem. [Jon Drukman <jsd gamespot.com>] PR#2933
9655 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
9656 platform, because it's only supported under version 4.0 and higher. But
9657 because our GuessOS is still unaware of Digital UNIX versions and the
9658 -msym is just to optimize the DSO statup time a little bit it's safe and
9659 best when we leave it out now. [Ralf S. Engelschall] PR#2969
9661 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
9662 functions: First all three functions no longer fail on strings containing
9663 "%" chars and second ap_log_printf() no longer does a double-formatting
9664 (instead it directly passes through the message to be formatted to the
9665 real internal formatting function). [Ralf S. Engelschall] PR#2941
9667 *) Allow "Include" directives anywhere in the server config
9668 files (but not .htaccess files). [Ken Coar] PR#2727
9670 *) The proxy was refusing to serve CONNECT requests except to
9671 port 443 (https://) and 563 (snews://). The new AllowCONNECT
9672 directive allows the configuration of the ports to which a
9673 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
9675 *) mod_expires will now act on content that is not sent from a file
9676 on disk. Previously it would never add an Expires: header to
9677 any response that did not come from a file on disk; the only
9678 case where it still doesn't (and can't) add one for that type of
9679 content is if you are using a modification date based setting.
9680 [Marc Slemko, Paul Phillips <paulp go2net.com>]
9682 *) Problems encountered during .htaccess parsing or CGI execution
9683 that lead to a "500 Server Error" condition now provide explanatory
9684 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
9687 *) Add NameWidth keyword to IndexOptions directive so that the
9688 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
9691 *) Recognize lowercase _and_ uppercase `uname' results under
9692 SCO OpenServer. [David Coelho <drc ppt.com>]
9694 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
9695 a common problem of (mis-administrated?) IIS servers, make the apache
9696 proxy immune to these errors (and ignore the duplicates, but log
9697 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
9699 *) The <IfModule and <IfDefine block starting directives now only
9700 allow exactly one argument. Previously, the optional negation
9701 character '!' could be separated by whitespace without a syntax
9702 error being reported, albeit defeating the IfModule functionality
9703 (enclosed directives would ALWAYS be executed). By using the
9704 stricter syntax, these hard-to-track errors can be avoided.
9707 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
9708 cause the standalone FancyIndexing directive to logically OR
9709 into any existing IndexOptions settings rather than wiping
9710 them out. [Ken Coar]
9712 *) Changes in ftp proxy: make URL parsing simpler by using the
9714 + Add display of the "current directory" in cases where it's
9715 different from the supplied path (e.g., ftp://user@host/ lives
9716 in /home/user, not in /, therefore clicking on "../" in the
9717 starting directory might send us to /home/).
9718 + When ftp login fails, (esp. when a user name was part of the
9719 URL already), we now return [401 Unauthorized ] to allow the
9720 browser to pop up an authorization dialog. This makes passwords
9721 slightly less visible (they don't appear in the regular log files)
9722 and implements a functionality that other www proxy servers
9726 *) Triggered by the recent "Via:" header changes, the proxy module would
9727 dump core for replies with invalid headers (e.g., duplicate
9728 "HTTP/1.0 200 OK" lines). These errors are now logged and the
9729 core dump is avoided. Also, broken replies are not cached.
9730 [Martin Kraemer] PR#2914
9732 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
9733 plop gmon.out profile data for each child [Doug MacEachern]
9735 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
9736 config.status script to be immune against arguments with whitespaces.
9737 [Yves Arrouye <yves apple.com>] PR#2866
9739 *) Replace the inlined information grabbing stuff for the configuration
9740 adjustment feature (no --without-confadjust) with calls to a new helper
9741 script `buildinfo.sh' which is both more flexible and already proofed to
9742 be more robust against platform differences. This mainly fixes the
9743 recently occured ``sed: command garbled: ...'' problems.
9744 [Ralf S. Engelschall] PR#2776, PR#2848
9746 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
9747 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
9748 without complains after we recently added the POST feature.
9749 [Ralf S. Engelschall]
9751 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
9752 modules as API functions and we forgot them at the big symbol renaming.
9753 [Ralf S. Engelschall]
9755 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

9761 *) Add the ability to do POST requests to the ab benchmarking tool.
9762 [Kurt Sussman <kls best.com>] PR#2871
9764 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
9765 5 to 10 because there are some users out there who always have 5 to 8
9766 variables in one RewriteRule and had to patch mod_rewrite.h for every
9767 release. So 15 should be now more than enough, even for them. (I never
9768 needed more than 4 in my RewriteRules ;-)
9769 [Ralf S. Engelschall]
9771 *) Make the proxy generate and understand Via: headers
9774 *) Change the proxy to use tables instead of array_headers for
9775 the header lines. [Martin Kraemer]
9777 *) Make sure the config.status file is not overridden when just
9778 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
9780 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
9781 provide a way to trace API changes that add functionality but do
9782 not create a compatibility issue for precompiled modules, etc.
9783 See include/ap_mmn.h for more details. [Randy Terbush]
9785 *) Fix suexec installation under `make install root=xxx' situation.
9786 [Ralf S. Engelschall]
9788 *) Extend the output of the -V switch to include the paths of all
9789 compiled-in configuration files, if they were overridden at
9790 compile time, for least astonishment of the user.
9793 *) When READing a request in ExtendedStatus mode, the "old"
9794 vhost, request and client information is not displayed.
9797 *) STATUS is no longer available. Full status information now
9798 run-time configurable using the ExtendedStatus directive.
9801 *) SECURITY: CVE-1999-1199 (cve.mitre.org)
9802 Eliminate O(n^2) space DoS attacks (and other O(n^2)
9803 cpu time attacks) in header parsing. Add ap_overlap_tables(),
9804 a function which can be used to perform bulk update operations
9805 on tables in a more efficient manner. [Dean Gaudet]
9807 *) SECURITY: Added compile-time and configurable limits for
9808 various aspects of reading a client request to avoid some simple
9809 denial of service attacks, including limits on maximum request-line
9810 size (LimitRequestLine), number of header fields (LimitRequestFields),
9811 and size of any one header field (LimitRequestFieldsize). Also added
9812 a configurable directive LimitRequestBody for limiting the size of the
9813 request message body. [Roy Fielding]
9815 *) Make status module aware of DNS and logging states, even if
9816 STATUS not defined. [Jim Jagielski]
9818 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
9820 *) Enhance mod_speling so that CheckSpelling can be used in

9824 ErrorDocument mechanism at runtime [Doug MacEachern]
9826 *) API: new ap_uuencode() function [Doug MacEachern]
9828 *) API: scan_script_header_err_core() now "public" and renamed
9829 ap_scan_script_header_err_core() [Doug MacEachern]
9831 *) The 'status' module will now show the process pid's and their
9832 state even without full STATUS accounting. [Jim Jagielski]
9834 *) Restore the client IP address to the error log messages, this
9835 was lost during the transition from 1.2 to 1.3. Add a new
9836 function ap_log_rerror() which takes a request_rec * and
9837 formats it appropriately. [Dean Gaudet] PR#2661
9839 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
9840 whitespace in input lines -- including within quoted strings.
9842 but leading and trailing whitespace should continue to be
9843 stripped [Martin Kraemer]
9845 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
9846 the ugly use of an env. variable and use command-line args for
9847 alternate $PATH. Make more like advanced 'type's as well.
9850 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
9851 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
9852 <alain.st-denis ec.gc.ca>] PR#2736
9854 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
9856 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
9857 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
9858 directory was renamed to src/os/os2/ for consistency.
9859 [Brian Havard, Ralf S. Engelschall]
9861 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
9862 files (here modules) against other DSO files (here shared libraries).
9863 This is done by determining a subset of LIBS which can be safely used for
9864 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
9865 disabled for all platforms to avoid problems with this (experimental)
9866 rule. But we provide it now for those people how ran into problems and
9867 want to came out by forcing linking against DSOs.

9886 *) One more portability fix for APACI shadow tree support: Swap order of awk
9887 and sed in top-level configure script to avoid sed fails on some

9951 up to a predetermined depth. [Martin Kraemer]
9953 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled
9954 (compilers complained) and the .so.V.R.P filename extension was adjusted
9955 to correctly reflect the 1.3.2 version.

9961 *) PORT: implement serialized accepts for OS/2. [Brian Havard]
9963 *) mod_include had problems with the fsize and flastmod directives
9964 under WIN32. Fix also avoids the minor security hole of using

9985 the scheme://sitepart string only, or to omit the query string.
9988 *) WIN32: Canonicalize ServerRoot before checking to see if it
9989 is a valid directory. The failure to do this caused certain

9991 rejected. [Marc Slemko]
9993 *) Global renaming of C header files to both get rid of conflicts with third
9994 party packages and to again reach consistency:
9995 1. conf.h -> ap_config.h
9996 2. conf_auto.h -> ap_config_auto.h \ these are now merged
9997 3. ap_config.h -> ap_config_auto.h / in the config process

9999 5. apctype.h -> ap_ctype.h
10000 Backward compatibility files for conf.h and compat.h were created.
10002 *) mod_mmap_static will no longer take action on requests unless at
10003 least one "mmapfile" directive is present in the configuration.
10004 This experimental module has to do some black magic to operate
10005 inside the current API and thus creates side-effects for other
10006 modules under some circumstances.

10013 *) mod_rewrite created RewriteLock files under the UID of the parent
10014 process, thus the child processes had no write access to the files.
10015 Now a chown() is done on the file to the uid of the children,
10016 if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341
10018 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via

10020 accurate platform definitions. This way we no longer have to fiddle with
10021 OS-type and/or OS-version identifiers to discover whether a system header
10022 file exists or not. Instead we now directly check for the existence of
10023 those esoteric ones.

10030 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
10031 modules to load their own modules dynamically. This improves mod_perl
10032 and mod_php3 when these modules are loaded dynamically into Apache.
10035 *) Cache a proxied request in the event that the client cancels the

10064 if the installation prefix didn't already contain "apache", but
10065 it should be because the DSO files are Apache-specific. Now
10066 libexecdir is treated the same way sysconfdir, datadir, localstatedir

10114 *) PORT: Change support/apachectl to use "kill -0 $pid" to test if the
10115 httpd is running. This should be more portable than figuring out
10116 which of three dozen different versions of "ps" are installed.
10119 *) WIN32: If we can't figure out how to execute a file in a script
10120 directory, bail out of the request with an error message. [W G Stoddard]
10122 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
10123 these are treated by Win32 as if they are ".." but are not detected by
10124 other machinery within Apache. This is something of a kludge but
10125 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
10127 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
10128 pools and thus pollutes libap (until the pool stuff is moved there).
10131 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
10132 but case-insensitive platforms). New #define for this added to conf.h
10133 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455

10141 *) Let APACI's configure script determine some configuration parameters
10142 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
10143 remove some of the classical hurdles for new users when setting up
10144 Apache. This is done per default because it is useful for the average
10145 user. Package authors can use the --without-confadjust option to disable
10146 these configuration adjustments.
10147 [Ralf S. Engelschall]
10149 *) Added an EXTRA_DEPS configuration parameter which can be used
10150 to add an extra Makefile dependency for the httpd target, for instance
10151 to external third-party libraries, etc.
10152 [Ralf S. Engelschall]
10154 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
10155 as <IfModule>..</IfModule> sections) which can be used to skip or process
10156 contained commands dependend of ``-D PARAMETER'' options on the command
10157 line. This can be used to achieve logical conditions like <IfDefine
10158 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
10159 and thus especially can be used for conditionally loading DSO-based
10160 modules via LoadModule, etc. [Ralf S. Engelschall]

10164 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]

10167 truncated which forced following HTTP headers to be data in the HTTP
10168 reponse. [Ralf S. Engelschall, Charles Fu <ccwf bacchus.com>]
10171 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
10172 in top-level configure script to avoid sed fails on some platforms (for
10173 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
10174 output of Awk. [Bill Houle <bhoule sandiegoca.ncr.com>] PR#2435
10176 *) Improve performance of directory listings (mod_autoindex) by comparing
10177 integer keys (last-modified and size) as integers rather than converting
10178 them to strings first. Also use a set of explicit byte tests rather
10179 than strcmp() to check for parent directory-ness of an entry. Oh, and
10180 make sure the parent directory (if displayed) is *always* listed first
10181 regardless of the sort key. Overall performance winnage should be good
10182 in CPU time, instruction cache, and memory usage, particularly for large
10183 directories. [Ken Coar]
10185 *) Add a tiny but useful goody to APACI's configure script: The generation
10186 of a config.status script (as GNU Autoconf does) which remembers the used
10187 configure command and hence can be used to restore the configuration by
10188 just re-running this script or for remembering the configuration between
10190 [Ralf S. Engelschall]
10192 *) Add httpd -t (test) option for running configuration syntax tests only.
10193 If something is broken it complains and exits with a return code
10194 non-equal to 0. This can be used manually by the user to check the Apache
10195 configuration after editing and is also automatically used by apachectl
10196 on (graceful) restart command to make sure Apache doesn't die on restarts
10197 because of a configuration which is now broken since the last (re)start.
10198 This way `apachectl restart' can be used inside cronjobs without having
10199 to expect Apache to be falling down. Additionally the httpd -t can be run
10200 via `apachectl configtest'.

10339 ap_spawn_child_err_buff became ap_bspawn_child
10340 spawn_child was obsoleted and moved to compat.h
10343 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
10344 programs: ap_spawn_child_err() is used and the Win32 case now uses
10345 CreateProcess() instead of a low-level execl() (which caused problems in
10346 the past under Win32).
10347 [Ralf S. Engelschall]
10349 *) A few cosmetics and trivial enhancements to APXS to make the
10350 generated Makefile more user friendly. [Ralf S. Engelschall]
10352 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
10353 was updated to use the normal apache error processing, thereby allowing
10354 proxy errors to be treated by ErrorDocument's as well. For this
10355 purpose, a new module-to-core communication variable "error-notes"
10356 was introduced; the proxy (and possibly other modules) communicates
10357 its error text using this variable. Its content is copied to a new
10358 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
10359 The old proxy special error routine ap_proxy_log_uerror()
10360 was replaced by regular ap_log_error() calls, many messages were made

10364 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
10367 *) Transform the configure message "You need root privileges for suEXEC"
10368 from a fatal error into a (more friendly) warning because the building
10369 ("make") of Apache we can allow, of course. Root privileges are needed
10370 only for the installation step ("make install"). So make sure the
10371 user is aware of this fact but let him proceed as long as he can.

10433 [Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
10435 *) The proxy cache would store an incorrect content-length in the cached
10436 file copy after a cache update. That resulted in repeated fetching
10437 of the original copy instead of using the cached copy.
10438 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
10440 *) The Makefiles assumed that DSO files are build via $(LD). This
10441 is broken for two reasons: First we never defined at least LD=ld
10442 somewhere to make sure this works (it was silently assumed that most Make
10443 provide a built-in LD definition - ARGL!) and second using the generic LD
10444 variable is not the truth. Instead a special variable named LD_SHLIB is
10445 reasonable because although "ld" is usually the default, the command for
10446 building DSO files can be "libtool" or even "cc" on some systems.
10447 [Ralf S. Engelschall]
10449 *) Replace the AddVersionPlatform directive with ServerTokens which
10450 provides for more control over the format of the Server:
10451 header line. SERVER_SUBVERSION is no longer supported;
10452 all module should use the ap_add_version_component()
10453 API function instead. [Jim Jagielski]
10455 *) Support for the NCR MP/RAS 3.0
10456 [John Withers <withers semi.kcsc.mwr.irs.gov>]
10458 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
10459 not retrieved in src/Configure and thus was not useable.
10460 [Ralf S. Engelschall]
10462 *) Various Makefile consistency cleanups:
10463 - make OSDIR also automatically be relative to src/ like INCDIR
10464 - SUBDIRS is now generated in src/Makefile only and not in
10465 Makefile.config because it is a local define for this location.
10466 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
10467 any Makefile but make sure that at least the "-K inline" is kept in
10469 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
10470 - updated the dependencies theirself
10471 - removed not existing SHLIB variable from "clean" targets
10472 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
10473 already exists and OBJS_PIC are also just plain objects and have not
10474 directly to do with "shared" things. The only difference is that they
10475 contain PIC. So OBJS_PIC is the more canonical name.
10476 - Updated the Makefile-dependency lines for OBJS_PIC
10477 - Removed the Makefile-dependency line in Configure to avoid double
10479 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
10480 of xxx.lo as GNU libtool does with its PIC objects
10481 - reduce local complexity in modules Makefile.tmpl by moving the last
10482 existing target "depend" to the generation section in Configure, too.
10483 - removed the historical $(SPACER) which was used in the past together
10484 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
10485 is no longer needed.
10486 - force the build and run of the gen_xxx programs under main/ as the
10487 first step before building the objects because it looks cleaner
10488 [Ralf S. Engelschall]
10490 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
10493 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
10496 *) WIN32: Don't force ISAPI headers to finish with \n.
10497 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
10499 *) When opening "configuration" files (like httpd.conf, htaccess
10500 and htpasswd), Apache will not allow them to be non-/dev/null
10501 device files. This closes a DoS hole. At the same time,
10502 we use ap_pfopen to open these files to handle timeouts.
10503 [Jim Jagielski, Martin Kraemer]
10505 *) Apache will now log the reason its httpd children exit if they exit
10506 due to an unexpected signal. (It requires a new porting define,
10507 SYS_SIGLIST, which if defined should point to a list of text
10508 descriptions of the signals available. See PORTING.) [Dean Gaudet]
10510 *) WIN32: chdir() doesn't make sense in a multithreaded environment
10511 like WIN32. Before, Win32 CGI's could have had sporadic failures
10512 if a chdir call from one thread was made between another chdir call
10513 and a spawn in another thread. So, for now don't chdir for CGI scripts
10514 in WIN32. The current CGI "spec" is unclear as to whether it's
10515 necessary. Long-term fix is to either serialize the chdir/spawn combo
10516 or use WIN32 native calls to spawn a process. This temp fix was
10517 necessary to remove this as a showstopper for 1.3's release.
10520 *) Cleanup the suEXEC support in APACI and make it more safe:
10521 1. Add big fat hint in INSTALL about risks and to read the
10522 htdocs/manual/suexec.html document before using the suexec-related
10524 2. Make sure the user has at least provided one --suexec-xxxx option
10525 (specifies suEXEC parameters) in addition to --enable-suexec option.
10526 If only --enable-suexec is given APACI stops with a hint to INSTALL
10527 and htdocs/manual/suexec.html documents.
10528 3. Provide two additional --suexec-xxxx options to make the suEXEC
10529 configuration complete (especially for package maintainers who else
10530 had to patch the source tree) by providing ways to configure minimal
10531 UID/GID and safe PATH, too.
10532 [Ralf S. Engelschall]
10534 *) Cleanup of the `configure --shadow' process:
10535 - make sure the configure script creates its temporary files in the
10536 shadow tree to avoid conflicts with parallel configure runs
10537 - removed unnecessary option "-r" from "rm" call for Makefiles
10538 - make sure the configure scripts creates the shadow-wrapper Makefile
10539 only when no shadow trees already exists
10540 - make sure "make distclean" removes the shadow-wrapper Makefile but only
10541 when no more shadow trees exists
10542 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
10543 as fast (in the past it needed 70sec, now it runs just 38sec)
10544 - make sure CVS does not complain about the created files
10545 Makefille.<gnutriple> and directories src.<gnutriple>
10546 [Ralf S. Engelschall]
10548 *) Added the ap_add_version_component() API routine and the
10549 AddVersionPlatform core directive. The first allows modules to
10550 declare themselves in the Server response header field value,
10551 augmenting the SERVER_SUBVERSION define in the Configuration file
10552 with run-time settings (more useful in a loadable-module environment).
10553 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
10554 into the server version string. [Ken Coar] PR#2056
10556 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
10559 *) Emit the "Accept-Range" header for the default handler.
10560 [Brian Behlendorf] PR#1464
10562 *) Add a note to httpd.conf-dist that apache will on some systems fail
10563 to start when the Group # is set to a negative or large positive value.
10566 *) Make sure the module execution order is correct even when some modules
10567 are loaded under runtime (`LoadModule') via the DSO mechanism:
10568 1. The list of loaded modules is now a dynamically allocated one
10569 and not the original statically list from modules.c
10570 2. The loaded modules are now correctly setup by LoadModule for
10571 later use by the AddModule command.
10572 3. When the DSO mechanism for modules is used APACI's `install'
10573 target now enables all created `LoadModule' lines per default because
10574 this is both already expected by the user _and_ needed to avoid
10575 confusion with the next point and reduces the Makefile.tmpl complexity
10576 4. When the DSO mechanism for modules is used, APACI's `install'
10577 target now additionally makes sure the module list is reconstructed
10578 via a complete `ClearModuleList+AddModule...' entry.
10579 5. The support tool `apxs' now also makes sure an AddModule command
10580 is added in addition to the LoadModule command.
10581 6. The modules.c generation was extended to now contain two
10582 comments to make sure no one is confused by the confusing terminology
10583 of loading/linking (we use load=link+load & link=activate instead of
10584 the obvious load=activate & link=link :-( )
10585 This way now there is no longer a difference under execution time between
10586 statically and dynamically linked modules.

10603 feature compatible with 'UseCanonicalName off' by changing
10604 r->server->server_hostname to ap_get_server_name(). And I changed some
10605 functions which use r->server->port to use ap_get_server_port() instead,
10606 because if there's no Port directive in the config r->server->port is 0.

10624 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in

10657 Additionally the checks for finding the vendor DSO library were moved
10658 from mod_so.c to Configure because first it needs $PLAT etc. and second
10659 mod_so already uses an abstraction layer and does not fiddle with the

10670 AIX variants should work fine, too. Even AIX 3.x should work). This is
10671 accomplished by using the free DSO emulation code from Jens-Uwe Mager
10672 which we put into a os/unix/os-dso-aix.c file.
10673 [Ralf S. Engelschall]
10675 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply

10679 *) Fix two bugs in select() handling in http_main.c.
10682 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
10683 is unset (as it is in situations like timeouts) where it is unclear
10684 whether errno is set or not. [Martin Kraemer]
10686 *) Just having APACI's localstatedir is too general and not enough for most
10687 of the systems. 1.3b6 again required manual APACI patches by package
10688 maintainers from Red Hat and FreeBSD because for their filesystem layout a
10689 little bit more flexibility in configuring the paths is needed. Hence we
10690 provide three additional configure options (--runtimedir, --logfiledir,
10691 --proxycachedir) which now can be used for more granular adjustments if
10692 --localstatedir is not enough to fit the particular needs. As a nice
10693 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
10694 [Ralf S. Engelschall]
10696 *) Make the install root for "make install" in APACI's Makefile overrideable
10697 by package authors. This way we are even more friendly to package
10698 maintainers (especially Debian and Red Hat) who build for the real prefix
10699 via "configure --prefix=/<real>" but use a different local prefix via
10700 "make root=/tmp/apache install" for rolling the package without bristling
10701 the target location on their system.
10702 [Ralf S. Engelschall]
10704 *) Workaround sed limitations in APACI's configure script by now
10705 substituting in chunks of 50 commands (because for instance HPUX's vendor

10820 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
10821 Make. [Ralf S. Engelschall]
10823 *) ++++ THE BIG SYMBOL RENAMING ++++
10824 To avoid symbol clashes with third-party code compiled into the server,
10825 we globally applied the prefix "ap_" to the following classes of
10827 - Apache provided general functions (e.g., ap_cpystrn)
10828 - Public API functions (e.g., palloc, bgets)
10829 - Private functions which we can't make static (because of
10830 cross-object usage) but should be (e.g., new_connection)
10831 For backward source compatibility a new header file named compat.h was
10832 created which provides defines for the old symbol names and can be used
10833 by third-party module authors.
10836 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
10837 problem under SVR4 is that there is no command flag to force the linker
10838 to export the global symbols of the httpd executable therewith they are
10839 available to the DSO's. Instead of problematic hacks like creating a
10840 dummy.so file (containing dummy references to all global symbols) the
10841 httpd binary is linked against, we use a clean trick stolen from Perl 5:
10842 Placing the Apache core code itself into a DSO library named libhttpd.so.
10843 This way the global symbols _HAVE_ to be exported and thus are available
10844 to any manually loaded DSO's under runtime. To reduce the impact to the
10845 user to null we go even further and create a stub httpd executable which
10846 automatically keeps track of the DSO library loading itself and thus
10847 hides the complete mechanism from the user. Although the generation of
10848 this DSO library is automatically triggered for platforms which
10849 essentially need it (mostly all SVR4-derivates) it can be also enabled
10850 manually via the Rule SHARED_CORE. This can be interesting in the future
10851 where we perhaps exploit this libhttpd.so mechanism for providing nifty
10852 features like graceful upgrades, or whatever.
10853 [Ralf S. Engelschall, Martin Kraemer]
10855 *) Build the libraries before building the rest of the tools. [Ben Hyde]
10857 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
10858 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
10859 conventions while "clean" removes only stuff created by "all" targets,
10860 "distclean" additionally removes the stuff from the configuration
10861 process. This way "make distclean" (hence the name) provides a fresh
10862 source tree as it was for distribution.
10863 [Ralf S. Engelschall]
10865 *) Allow top-level (APACI) Makefile to break on build errors
10866 the same way the src/ subtree Makefiles breaks on them by replacing the
10867 initial APACI sed-subdir-display-kludge with a more clean
10868 variable-passing-solution: variable SDP can optionally hold the subdir
10869 prefix which is consistently used for displaying the subdir movement.
10870 This way even the top-level Makefile can stop correctly on errors as the
10871 user expects. [Ralf S. Engelschall]

10886 *) Add documentation file and src/Configuration.tmpl entry for the
10887 experimental mod_mmap_static module. Because although it is and marked as
10888 an experimental one it is distributed and thus should be documented and
10889 prepared for configuration the same way as all others modules.
10890 [Ralf S. Engelschall]
10892 *) Add query (-q) option to apxs support tool to be able to manually query
10893 specific settings from apxs. This is needed for instance when you
10894 manually want to access Apache's header files and you need to assemble
10895 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
10896 [Ralf S. Engelschall]
10898 *) Now src/Configure uses a fallback strategy for the shared object support
10899 on platforms where no explicit information is available: If a Perl
10900 installation exists we ask it about its shared object support and if it's
10901 the dlopen-style one we shamelessly guess the compiler and linker flags
10902 for creating shared objects from Perls knowledge. Of course, the user is
10903 warning about what we are doing and informed that he should send us
10904 the guessed flags when they work. [Ralf S. Engelschall]
10906 *) Provide APACI --without-support option to be able to disable the build
10907 and installation of the support tools from the src/support/ area.
10908 Although its useful to have these installed per default we should provide
10909 a way to compile and install without them for backward-compatibility.
10910 [Ralf S. Engelschall]
10912 *) Add of the new APache eXtenSion (apxs) support tool for building and
10913 installing modules into an _already installed_ Apache package through the
10914 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
10915 this approach actually doesn't need the Apache source tree. The
10916 (APACI-installed) server package is enough, because this now includes the
10917 Apache C header files (PREFIX/include) and the new APXS tool
10918 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
10919 module authors to build their Apache modules _OUTSIDE_ the Apache source
10920 tree while avoiding them to fiddle around with the totally platform
10921 dependend way of compiling DSO files. The tool supports all ranges of
10922 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
10923 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
10924 on-the-fly generate a minimalistic Makefile and sample module for the
10925 first step to provide both a quick success event and to demonstrate the
10926 APXS mechanism to module authors. [Ralf S. Engelschall]
10928 *) Fix core dumps in use of CONNECT in proxy.
10929 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
10931 *) Modify the log directives in httpd.conf-dist files to use CustomLog
10932 so that users have examples of how CustomLog can be used.
10935 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
10936 the Apache distribution tree. Until Apache 1.3 there was no real
10937 out-of-the-box batch-capable build and installation procedure for the
10938 complete Apache package. This is now provided by a top-level "configure"
10939 script and a corresponding top-level "Makefile.tmpl" file. The goal is
10940 to provide a GNU Autoconf-style frontend which is capable to both drive
10941 the old src/Configure stuff in batch and additionally installs the
10942 package with a GNU-conforming directory layout. Any options from the old
10943 configuration scheme are available plus a lot of new options for flexibly
10944 customizing Apache. [Ralf S. Engelschall]
10946 *) The floating point ap_snprintf code wasn't threadsafe.
10947 Had to remove the HAVE_CVT macro in order to do threadsafe
10948 calling of the ?cvt() floating point routines. [Dean Gaudet]

10956 Configure knows which CC we are using. [Jim Jagielski]
10958 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
10959 was defined in a parent directory. [Lars Eilebrecht]
10961 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
10962 a generic printf-style routine that can call arbitrary output
10963 routines. Use this to replace http_bprintf.c. Add new routines
10964 psprintf(), pvsprintf() which allocate the exact amount of memory
10965 required for a string from a pool. Use psprintf() to clean up
10966 various bits of code which used ap_snprintf()/pstrdup().
10969 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
10970 ap_snprintf() has different semantics and formatting codes than
10971 snprintf(). [Dean Gaudet]
10973 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
10974 is necessary on at least Solaris where the /etc/rc?.d scripts
10975 are run with these signals ignored, and "SIG_IGN" settings are
10976 maintained across exec().

11002 [Jürgen Keil <jk tools.de>] PR#2000
11004 *) Allow %2F in two situations: 1) it is in the query part of the URI,
11005 therefore not exposed to %2F -> '/' translations and 2) the request
11006 is a proxy request, so we're not dealing with a local resource anyway.
11007 Without this, the proxy would fail to work for any URL's with
11008 %2f in them (occurs quite often in
11009 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
11011 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
11013 *) Make the shared object compilation command more portable by avoiding
11014 the direct combination of `-c' & `-o' which is not honored by some
11015 compilers like UnixWare's cc. [Ralf S. Engelschall]
11017 *) WIN32: the proxy was creating filenames missing the last four
11018 characters. While this normally doesn't stop anything from
11019 working, it can result in extra collisions.

11024 header if available. [Ralf S. Engelschall] PR#1183
11026 *) Reanimated the (still undocumented) proxy receive buffer size directive:
11027 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
11028 name was really too generic, added documentation for this directive to
11029 the mod_proxy.html and corrected the hyperlink to it in the

11038 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
11039 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
11040 and per default compiled support programs have manual pages - just to
11041 document our stuff a little bit more and to be able to do really
11042 Unix-like installations ;-) [Ralf S. Engelschall]
11044 *) Major cleanups to the Configure script to make it and its generated
11045 Makefiles again readable and maintainable: add SRCDIR option, removed
11046 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
11047 generated sections, consequently added Makefile headers with inheritance
11048 information, added subdir movement messages for easier following where
11049 the build process currently stays (more verbose then standard Make, less
11050 verbose than GNU make), same style to comments in the Configure script,
11051 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
11053 *) Add the new ApacheBench program "ab" to src/support/: This is derived
11054 from the ZeusBench benchmarking program and can be used to determine the
11055 response performance of an Apache installation. This version is
11056 officially licensed with Zeus Technology, Ltd. See the license agreement

11060 *) API: Various core functions that are definately not part of the API
11061 have been made static, and a few have been marked API_EXPORT. Still
11062 more have been marked CORE_EXPORT and are not intended for general
11063 use by modules. [Doug MacEachern, Dean Gaudet]
11065 *) mod_proxy was not clearing the Proxy-Connection header from
11066 requests; now it does. This did not violate any spec, however
11067 causes poor interactions when you are talking to remote proxies.

11076 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
11078 *) Clean up some undocumented behavior of mod_setenvif related to
11079 "merging" two SetEnvIf directives when they match the same header
11080 and regex. Document that mod_setenvif will perform comparisons in
11081 the order they appear in the config file. Optimize mod_setenvif by
11082 doing more work at config time rather than at runtime.
11085 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
11086 to allow for modules to overrule them and to reduce redefinition
11087 warnings [Jim Jagielski]
11089 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
11092 *) Making the hard-coded cross-module function call mime_find_ct() (from
11093 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
11094 checking is really called even for proxy requests except for URLs with
11095 HTTP schemes (because there we can optimize by not running the type
11096 checking hooks due to the fact that the proxy gets the MIME Content-type
11097 from the remote host later). This change cleans up mod_mime by removing
11098 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
11099 especially unbundles mod_proxy and mod_mime. This way they both now can
11100 be compiled as shared objects and are no longer tied together.
11101 [Ralf S. Engelschall]
11103 *) util.c cleanup and speedup. [Dean Gaudet]
11105 *) API: Clarification, pstrndup() will always copy n bytes of the source
11106 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
11108 *) Mark module command_rec and handler_rec structures const so that they
11109 end up in the read-only data section (and are friendlier to systems
11110 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
11112 *) Add check to the "Port" directive to make sure the specified
11113 port is in the appropriate range. [Ben Hyde]
11115 *) Performance improvements to invoke_handler().
11116 [Dmitry Khrustalev <dima bog.msu.su>]
11118 *) Added support for building shared objects even for library-style modules
11119 (which are built from more than one object file). This now provides the
11120 ability to build mod_proxy as a shared object module. Additionally
11121 modules like mod_example are now also supported for shared object
11122 building because the generated Makefiles now no longer assume there is at
11123 least one statically linked module. [Ralf S. Engelschall]
11125 *) API: Clarify usage of content_type, handler, content_encoding,
11126 content_language and content_languages fields in request_rec. They
11127 must always be lowercased; and the strings pointed to shouldn't
11128 be modified (you must copy them to modify them). Fix a few bugs
11129 related to this. [Dean Gaudet]
11131 *) API: Clarification: except for RAW_ARGS, all command handlers can
11132 treat the char * parameters as permanent, and modifiable. There
11133 is no need to pstrdup() them. Clean up some needless pstrdup().
11136 *) Now mod_so keeps track of which module shared objects with which names
11137 are loaded and thus avoids multiple loading and unloading and irritating
11138 error_log messages. [Ralf S. Engelschall]
11140 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
11141 environment variable in the apache core. But that tweaking interferes
11142 with mod_setenv. So don't tweak if the user has specified an explicit
11143 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888

11150 it to the IP address when unavailable.
11151 [Tony Finch <fanf demon.net>] PR#1925
11153 *) Various improvements to the configuration and build support for compiling
11154 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
11155 OSF1 support with GCC and vendor compilers was added. This way shared
11156 object support is now provided out-of-the-box for FreeBSD, Linux,
11157 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!

11160 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
11161 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
11162 and USE_OS2_SCOREBOARD. [Dean Gaudet]
11164 *) Fix one more special locking problem for RewriteMap programs in
11165 mod_rewrite: According to the documentation of flock(), "Locks are on
11166 files, not file descriptors. That is, file descriptors duplicated
11167 through dup(2) or fork(2) do not result in multiple instances of a lock,
11168 but rather multiple references to a single lock. If a process holding a
11169 lock on a file forks and the child explicitly unlocks the file, the
11170 parent will lose its lock.". To overcome this we have to make sure the
11171 RewriteLock file is opened _AFTER_ the childs were spawned which is now
11172 the case by opening it in the child_init instead of the module_init API
11173 hook. [Ralf S. Engelschall] PR#1029
11175 *) Change to Location and LocationMatch semantics. LocationMatch no
11176 longer lets a single slash match multiple adjacent slashes in the
11177 URL. This change is for consistency with RewriteRule and
11178 AliasMatch. Multiple slashes have meaning in URLs that they do
11179 not have in (some) filesystems. Location on the other hand can
11180 be considered a shorthand for a more complicated regex, and it
11181 does match multiple slashes with a single slash -- which is
11182 also consistent with the Alias directive.
11183 [Dean Gaudet] related PR#1440
11185 *) Fix bug with mod_mime_magic causing certain files, including files
11186 of length 0, to result in no response from the server.
11189 *) The Configure script now generates src/include/ap_config.h which
11190 contains the set of defines used when Apache is compiled on a platform.
11191 This file can then be included by external modules before including
11192 any Apache header files in case they are being built separately from
11193 Apache. Along with this change, a couple of minor changes were
11194 made to make Apache's #defines coexist peacefully with any autoconf
11195 defines an external module might have. [Rasmus Lerdorf]
11197 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
11198 but without any RewriteXXXXX directives. Here mod_rewrite is given no
11199 chance by the API to initialize its per-server configuration and thus
11200 receives the wrong one from the main server. This is now avoided by
11201 remembering the server together with the config structure while
11202 configuring and later assuming there is no config when we see a
11203 difference between the remembered server and the one calling us.
11204 [Ralf S. Engelschall] PR#1790
11206 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
11207 is automatically disabled under configure time when the dbm_xxx functions
11208 are not available. Second, two heavy source code errors in the DBM
11209 support code were fixed. This makes DBM RewriteMap's usable again after
11210 a long time of brokenness. [Ralf S. Engelschall] PR#1696
11212 *) Now all configuration files support Unix-style line-continuation via
11213 the trailing backslash ("\") character. This enables us to write down
11214 complex or just very long directives in a more readable way. The
11215 backslash character has to be really the last character before the
11216 newline and it has not been prefixed by another (escaping) backslash.

11232 depending on the rev of Solaris and what mixture of modules
11233 are in use. So it has been disabled, and Solaris is back to
11234 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
11235 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
11236 up static content only servers. Or it may fail unpredictably.

11239 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
11242 *) API: Rewrite of absoluteURI handling, and in particular how
11243 absoluteURIs match vhosts. Unless a request is a proxy request, a
11244 "http://host" url is treated as if a similar "Host:" header had been
11245 supplied. This change was made to support future HTTP/1.x protocols
11246 which may require clients to send absoluteURIs for all requests.
11248 In order to achieve this change subtle changes were made to the API. In a
11249 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
11250 that the unmodified uri can be retrieved easily. r->proxyreq is not set
11251 by the core, modules must set it during the post_read_request or
11252 translate_names phase.
11254 Plus changes to the virtualhost test suite for absoluteURI testing.
11256 This fixes several bugs with the proxy proxying requests to vhosts
11257 managed by the same httpd.

11278 *) API: A new source module main/util_uri.c; It contains a routine
11279 parse_uri_components() and friends which breaks a URI into its component
11280 parts. These parts are stored in a uri_components structure called
11281 parsed_uri within each request_rec, and are available to all modules.
11282 Additionally, an unparse routine is supplied which re-assembles the URI
11283 components back to an URI, optionally hiding the username:password@ part
11284 from ftp proxy requests, and other useful routines. Within the structure,
11285 you find on a ready-for-use basis:
11286 scheme; /* scheme ("http"/"ftp"/...) */
11287 hostinfo; /* combined [user[:password]@]host[:port] */
11288 user; /* user name, as in http://user:passwd@host:port/ */
11289 password; /* password, as in http://user:passwd@host:port/ */
11290 hostname; /* hostname from URI (or from Host: header) */
11291 port_str; /* port string (integer representation is in "port") */
11292 path; /* the request path (or "/" if only scheme://host was given) */
11293 query; /* Everything after a '?' in the path, if present */
11294 fragment; /* Trailing "#fragment" string, if present */
11295 This is meant to serve as the platform for *BIG* savings in
11296 code complexity for the proxy module (and maybe the vhost logic).
11299 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and

11350 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
11351 Jay Soffian <jay cimedia.com>] PR#1631
11353 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
11354 This directive lets Apache adjust the URL in Location-headers on HTTP
11355 redirect responses sent by the remote server. This way the virtually
11356 mapped area is no longer left on redirects and thus by-passed which is
11357 especially essential when running Apache as a reverse proxy.

11468 *) MiNT port update. [Jan Paul Schmidt]
11470 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
11471 equivalent, similarly for x-compress and compress. Apache
11472 now ignores a leading x- when comparing encodings. It also
11473 preserves the encoding the client requests (for example if
11474 it requests x-gzip, then Apache will respond with x-gzip
11475 in the Content-Encoding header).

11478 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
11480 *) Added mod_so module to support dynamic loading of modules on Unix

11482 instead of AddModule in Configuration to build shared modules
11483 [Sameer Parekh, Paul Sutton]
11485 *) Minor cleanups to r->finfo handling in some modules.
11488 *) Abstract read()/write() to ap_read()/ap_write().
11489 Makes it easier to add other types of IO code such as SFIO.
11492 *) API: Generalize default_port manipulations to make support of
11493 different protocols easier. [Ben Laurie, Randy Terbush]
11495 *) There are many cases where users do not want Apache to form
11496 self-referential urls using the "canonical" ServerName and Port.
11497 The new UseCanonicalName directive (default on), if set to off
11498 will cause Apache to use the client-supplied hostname and port.
11499 API: Part of this change required a change to the construct_url()
11500 prototype; and the addition of get_server_name() and
11502 [Michael Douglass <mikedoug texas.net>, Dean Gaudet]
11503 PR#315, 459, 485, 1433
11505 *) Yet another rearrangement of the source tree.. now all the common
11506 header files are in the src/include directory. The -Imain -Iap
11507 references in Makefiles have been changed to the simpler -Iinclude
11508 instead. In addition to simplifying the build a little bit, this
11509 also makes it clear when a module is referencing something in a
11510 other than kosher manner (e.g., the proxy including mod_mime.h).
11511 Module-private header files (the proxy, mod_mime, the regex library,
11512 and mod_rewrite) have not been moved to src/include; nor have
11513 the OS-abstraction files. [Ken Coar]
11515 *) Fix a bug where r->hostname didn't have the :port stripped
11516 from it. [Dean Gaudet]
11518 *) Tweaked the headers_out table size, and the subprocess_env
11519 table size guess in rename_original_environment(). Added
11520 MAKE_TABLE_PROFILE which can help discover make_table()
11521 calls that use too small an initial guess, see alloc.c.
11524 *) Options and AllowOverride weren't properly merging in the main
11525 server setting inside vhosts (only an issue when you have no
11526 <Directory> or other section containing an Options that affects
11527 a request). Options +foo or -foo in the main_server wouldn't
11528 affect the main_server's lookup defaults. [Dean Gaudet]
11530 *) Variable 'cwd' was being used pointlessly before being set.
11533 *) r->allowed handling cleaned up in the standard modules.
11536 *) Some case-sensitivity issues cleaned up to be consistent with
11537 RFC2068. [Dean Gaudet]
11539 *) SIGURG doesn't exist everywhere.
11540 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
11542 *) mod_unique_id was erroneously generating a second unique id when
11543 an internal redirect occured. Such redirects occur, for example,
11544 when processing a DirectoryIndex match. [Dean Gaudet]
11546 *) API: table_add, table_merge, and table_set include implicit pstrdup()
11547 of the key and value. But in many cases this is not required
11548 because the key/value is a constant, or the value has been built
11549 by pstrcat() or other similar means. New routines table_addn,
11550 table_mergen, and table_setn have been added to the API, these
11551 routines do not pstrdup() their arguments. The core code and
11552 standard modules were changed to take advantage of these routines.
11553 The resulting server is up to 20% faster in some situations.
11555 Note that it is easy to get code subtly wrong if you pass a key/value
11556 which is in a pool other than the pool of the table. The only
11557 safe thing to do is to pass key/values which are in the pool of
11558 the table, or in one of the ancestors of the pool of the table.
11559 i.e. if the table is part of a subrequest, a value from the main
11560 request's pool is OK since the subrequest pool is a sub_pool of the
11561 main request's pool (and therefore has a lifespan at most as long as
11562 the main pool). There is debugging code which can detect improper
11563 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
11564 [Dmitry Khrustalev <dima bog.msu.su>, Dean Gaudet]
11566 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
11567 which don't exist on disk more gracefully; handles vhosts properly.
11568 Update documentation to reflect the code -- if there's no
11569 MimeMagicFile directive then the module is not enabled.
11572 *) PORT: Some older *nix dialects cannot automatically start scripts
11573 which begin with a #! interpreter line (the shell starts the scripts
11574 appropriately on these platforms). Apache now supports starting of
11575 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
11576 [Martin Kraemer, with code from Peter Wemm <peter zeus.dialix.oz.au>
11579 *) API: "typedef array_header table" removed from alloc.h, folks should
11580 have been writing to use table as if it were an opaque type, but even
11581 some standard modules got this wrong. By changing the definition
11582 to "typedef struct table table" module authors will receive compile
11583 time warnings that they're doing the wrong thing. This change
11584 facilitates future changes with more sophisticated table
11585 structures. Specifically, module authors should be using table_elts()
11586 to get access to an array_header * for the table. [Dean Gaudet]
11588 *) API: Renamed new_connection() to avoid namespace collision with LDAP
11589 library routines. [Ken Coar, Rasmus Lerdorf]
11591 *) WIN32: mod_speling is now available on the Win32 platform.
11594 *) For clarity the following compile time definition was changed:
11596 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
11598 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
11599 and not be a general notice that the OS has mmap(). Now the
11600 HAVE_MMAP/SHMGET #defines strictly are informational that the
11601 OS has that method of shared memory; the type to use for
11602 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
11603 and USE_SHMGET_SCOREBOARD). This allows outside modules to
11604 determine if shared memory is available and allows Apache
11605 to determine the best method to use for the scoreboard.
11608 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
11609 as do various earlier versions. It should be safe on all versions.
11610 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
11611 the slack code. A few other cleanups for Unixware.

11615 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
11617 *) When die() happens we need to eat any request body if one exists.
11618 Otherwise we can't continue with a keepalive session. This shows up
11619 as a POST problem with MSIE 4.0, typically against pages which are
11620 authenticated. [Roy Fielding] PR#1399
11622 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization

11633 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
11634 The choice of flock vs. fcntl was made based on timings which showed that
11635 even on non-NFS, non-exported filesystems fcntl() was an order of
11636 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
11637 that single socket users will see no difference. [Dean Gaudet] PR#467
11639 *) "File does not exist" error message was erroneously including the
11640 errno. [Marc Slemko]
11642 *) Improve the warning message generated when a client drops the

11645 *) Defining GPROF will disable profiling in the parent and enable it
11646 in the children. If you're profiling under Linux this is pretty much
11647 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
11649 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.

11659 *) Some const declarations in mod_imap.c that were added for debugging
11660 purposes caused some compilers heartburn without adding any
11661 significant value, so they've been removed. [Ken Coar]
11663 *) The src/main/*.h header files have had #ifndef wrappers added to
11664 insulate them against duplicate calls if they get included through
11665 multiple paths (e.g., in .c files as well as other .h files).
11668 *) The libap routines now have a header file for their prototypes,
11669 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
11671 *) mod_autoindex with a plaintext header file would emit the <PRE>
11672 start-tag before the HTML preamble, rather than after the preamble
11673 but before the header file contents. [John Van Essen <jve gamers.org>]
11676 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
11677 only an issue on systems without a MAXDNAME define or where
11678 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
11680 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
11681 is used to read various types of files such as htaccess and
11682 htpasswd files. [Marc Slemko]
11684 *) SECURITY: Ensure that the buffer returned by ht_time is always
11685 properly null terminated. [Marc Slemko]
11687 *) The "Connection" header could be sent back with multiple "close"
11688 tokens. Not an error, but a waste.
11689 [<Ronald.Tschalaer psi.ch>] PR#1683
11691 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
11692 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
11694 *) "basic" auth needs a case-insensitive comparison.
11695 [<Ronald.Tschalaer psi.ch>] PR#1666
11697 *) For maximum portability, the environment passed to CGIs should
11698 only contain variables whose names match the regex
11699 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
11700 underscores over any character outside the regex. This
11701 affects HTTP_* variables, in a way that should be backward
11702 compatible for all the standard headers; and affects variables
11703 set with SetEnv/BrowserMatch and similar directives.
11706 *) mod_speling returned incorrect HREF's when an ambigous match

11789 *) send_fd_length() did not calculate total_bytes_sent properly.
11790 [Ben Reser <breser regnow.com>] PR#1366
11792 *) The bputc() macro was not properly integrated with the chunking
11793 code; in many cases modules using bputc() could cause completely
11794 bogus chunked output. (Typically this will show up as problems
11795 with Internet Explorer 4.0 reading a page, but other browsers
11796 having no problem.) [Dean Gaudet]
11798 *) Create LARGE_WRITE_THRESHOLD define which determines how many
11799 bytes have to be supplied to bwrite() before it will consider
11800 doing a writev() to assemble multiple buffers in one system
11801 call. This is critical for modules such as mod_include,
11802 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
11803 strings in some cases. The result would be extra effort
11804 setting up writev(), and in many cases extra effort building
11805 chunks. The default is 31, it can be overriden at compile
11806 time. [Dean Gaudet]

11874 now have a title in which the path components are clickable and allow
11875 quick navigation to the clicked-on directory on the currently listed
11876 ftp server. This also fixes a bug where the ".." directory links would

11915 This turns out to be a bug in Winsock - select() doesn't always

11918 *) Directives owned by http_core can now use the new check_cmd_context()
11919 routine to ensure that they're not being used within a container
11920 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
11922 *) PORT: Recent changes made it necessary to add explicit prototype
11923 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
11925 *) It was necessary to distinguish between resources which are
11926 allocated in the parent, for cleanup in the parent, and resources
11927 which are allocated in each child, for cleanup in each child.
11928 A new pool was created which is passed to the module child_init
11929 and child_exit functions; modules are free to register per-child
11930 cleanups there. This fixes a bug with reliable piped logs.
11933 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
11934 unless it was also doing FancyIndexes, but it displayed the
11935 HeaderName file at the top under all circumstances. It now shows
11936 the ReadmeName file for simple indices, too, as it should.
11939 *) http_core was mmap()ing even in cases where it wasn't going to
11940 read the file. [Ben Hyde <bhyde gensym.com>]
11942 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
11943 Now the rewriting engine (the heart of mod_rewrite) is organized more
11944 straight-forward, first time well documented and reduced to the really
11945 essential parts. All redundant cases were stripped off and processing now
11946 is the same for both per-server and per-directory context with only a
11947 minimum difference (the prefix stripping in per-dir context). As a
11948 side-effect some subtle restrictions and two recently discovered problems
11949 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
11950 context and restrictions on the substitution URL on redirects.
11951 Additionally some minor source cleanups were done.

12106 Changes with Apache 1.3b2 (there is no 1.3b1)
12108 *) TestCompile was not passing $LIBS [Dean Gaudet]
12110 *) Makefile.tmpl was not using $CFLAGS in the link phase.
12113 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
12114 rudimentary memory debugger which can be used on live servers with
12115 low impact -- it sets all allocated and freed memory bytes to 0xa5.
12116 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
12117 and free() for each object. This is far more expensive and should
12118 only be used for testing with tools such as Electric Fence and
12119 Purify. See main/alloc.c for more details. [Dean Gaudet]
12121 *) Configure uses a sh trap and didn't set its exitcode properly.
12122 [Dean Gaudet] PR#1159
12124 *) Yet another vhost revamp. Add the NameVirtualHost directive which
12125 explicitly lists the ip:port pairs that are to be used for name-vhosts.
12126 From a given ip:port, regardless what the Host: header is, you can
12127 only reach the vhosts defined on that ip:port. The precedence of
12128 vhosts was reversed to match other precedences in the config --
12129 the earlier vhosts override the later vhosts. All vhost matching was
12130 moved into http_vhost.[ch]. [Dean Gaudet]
12132 *) ap_inline can be used to force inlining. GNUC __attribute__() can
12133 be used for whatever reason is appropriate (i.e. format() warnings
12134 for printf style functions). Both are enabled only with
12135 gcc >= 2.7.x (so that we have fewer support issues with older
12136 versions). [Dean Gaudet]
12138 *) Fix support for Proxy Authentication (we were testing the response
12139 status too early). [Marc Slemko]
12141 *) CoreDumpDirectory directive directs where the core file is
12142 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
12143 received. [Marc Slemko, Dean Gaudet]
12145 *) PORT: Support for Atari MINT.
12146 [Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
12148 *) When booting, apache will now detach itself from stdin, stdout,
12149 and stderr. stderr will not be detached until after the config
12150 files have been read so you will be able to see initial error
12151 messages. After that all errors are logged in the error_log.
12152 This makes it more convenient to start apache via rsh, ssh,
12153 or crontabs. [Dean Gaudet] PR#523
12155 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
12156 Also removed the auto-generated link to www.apache.org that was the
12157 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
12159 *) send_fb would not detect aborted connections in some situations.
12162 *) mod_include would use uninitialized data when parsing certain
12163 expressions involving && and ||. [Brian Slesinsky] PR#1139
12165 *) mod_imap should only handle GET methods. [Jay Bloodworth]
12167 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
12169 *) mod_autoindex improperly counted &escapes; as more than one
12170 character in the description. It also improperly truncated
12171 descriptions that were exactly the maximum length.
12174 *) RedirectMatch was not properly escaping the result (PR#1155). Also
12175 "RedirectMatch /advertiser/(.*) $1" is now permitted.
12178 *) mod_include now uses symbolic names to check for request success
12179 and return HTTP errors, and correctly handles all types of
12180 redirections (previously it only did temporary redirect correctly).
12181 [Ken Coar, Roy Fielding]
12183 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
12184 r->filename. Since those two are meant to be in sync with each other
12185 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]

12194 reporting a select error over and over.

12197 *) Fixed error in proxy_util.c when looping through multiple host IP
12198 addresses. [Lars Eilebrecht] PR#974
12200 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
12201 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
12202 bytes before writing, but it will never split a log entry across a
12203 buffer boundary. [Dean Gaudet]
12205 *) API: the short_score record has been split into two pieces, one which
12206 the parent writes on, and one which the child writes on. As part of
12207 this change the get_scoreboard_info() function was removed, and
12208 scoreboard_image was exported. This change fixes a race condition
12209 in file based scoreboard systems, and speeds up changes involving the
12210 scoreboard in earlier 1.3 development. [Dean Gaudet]
12212 *) API: New register_other_child() API (see http_main.h) which allows
12213 modules to register children with the parent for maintenance. It
12214 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
12216 *) API: New piped_log API (see http_log.h) which implements piped logs,
12217 and will use register_other_child to implement reliable piped logs
12218 when it is available. The reliable piped logs part can be disabled
12219 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
12220 logs is only available on Unix. [Dean Gaudet]
12222 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
12223 meets_conditions(). This allows conditional HTTP selection to be
12224 handled separately from the storing of the header fields, and provides
12225 the ability for CGIs to set their own ETags for conditional checking.
12226 [Ken Coar, Roy Fielding] PR#895
12228 *) Changes to mod_log_config to allow naming of format strings.
12229 Format nicknames are defined with "LogFormat fmt nickname", and can
12230 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
12233 *) New module, "mod_speling", which can help find files even when
12234 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
12236 *) API: New function child_terminate() triggers the child process to
12237 exit, while allowing the child finish what it needs to for the
12238 current request first.
12239 [Doug MacEachern, Alexei Kosut]
12241 *) Windows now defaults to using full status reports with mod_status.
12242 [Alexei Kosut] PR #1094
12244 *) *Really* disable all mod_rewrite operations if the engine is off.
12245 Some things (like RewriteMaps) were checked/performed even if they
12246 weren't supposed to be. [Ken Coar] PR #991
12248 *) Implement a new timer scheme which eliminates the need to call alarm() all
12249 the time. Instead a counter in the scoreboard for each child is used to
12250 show when the child has made forward progress. The parent samples this
12251 counter every scoreboard maintenance cycle, and issues SIGALRM if no
12252 progress has been made in the timeout period. This reduces the static
12253 request best-case syscall count to 22 from 29. This scheme is only
12254 used by systems with memory-based scoreboards. [Dean Gaudet]
12256 *) The proxy now properly handles CONNECT requests which are sent
12257 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
12259 *) A script called apachectl has been added to the support
12260 directory. This script allows you to do things such as
12261 "apachectl start" and "apachectl restart" from the command
12262 line. [Marc Slemko]
12264 *) Modules and core routines are now put into libraries, which
12265 simplifies the link line tremendously (among other advantages).
12268 *) Some of the MD5 names defined in Apache have been renamed to have
12269 an `ap_' prefix to avoid conflicts with routines supplied by
12270 external libraries. [Ken Coar]
12272 *) Removal of mod_auth_msql.c from the distribution. There are many
12273 other options for databases today. Rather than offer one option,
12274 offer none at this time. mod_auth_msql and other SQL database
12275 authentication modules can be found at the Apache Module Registry.
12276 http://modules.apache.org/ It would be nice to offer a generic
12277 mod_auth_sql option in the near future.
12279 *) PORT: BeOS support added [Alexei Kosut]
12281 *) Configure no longer accepts the -make option, since it creates
12282 Makefile on the fly based on Makefile.tmpl and Configuration.
12284 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
12285 of forcibly killing off all its processes and exiting without
12286 cleaning up. [Alexei Kosut]
12288 *) API: A new field in the request_rec, r->mtime, has been added to
12289 avoid gratuitous parsing of date strings. It is intended to hold
12290 the last-modified date of the resource (if applicable). An
12291 update_mtime() routine has also been added to advance it if
12292 appropriate. [Roy Fielding, Ken Coar]
12294 *) SECURITY: If a htaccess file can not be read due to bad permissions,
12295 deny access to the directory with a HTTP_FORBIDDEN. The previous
12296 behavior was to ignore the htaccess file if it could not be read.
12297 This change may make some setups with unreadable htaccess files
12298 stop working. [Marc Slemko] PR#817
12300 *) Add aplog_error() providing a mechanism to define levels of
12301 verbosity to the server error logging. This addition also provides
12302 the ability to log errors using syslogd. Error logging is configurable
12303 on a per-server basis using the LogLevel directive. Conversion
12304 of log_*() in progress. [Randy Terbush]
12306 *) Further enhance aplog_error() to not log filename, line number, and
12307 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
12309 *) WIN32: Canonicalise filenames under Win32. Short filenames are
12310 converted to long ones. Backslashes are converted to forward
12311 slashes. Case is converted to lower. Parts of URLs that do not
12312 correspond to files are left completely alone. [Ben Laurie]
12314 *) PORT: 2 new OSs added to the list of ports:
12315 Encore's UMAX V: Arieh Markel <amarkel encore.com>
12316 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
12318 *) Add the server version (SERVER_VERSION macro) to the "server
12319 configured and running" entry in the error_log. Also build an
12320 object file at link-time that contains the current time
12321 (SERVER_BUILT global const char[]), and include that in the
12322 message. [Ken Coar]
12324 *) Set r->headers_out when sending responses from the proxy.
12325 This fixes things such as the logging of headers sent from
12326 the proxy. [Marc Slemko] PR#659
12328 *) support/httpd_monitor is no longer distributed because the
12329 scoreboard should not be file based if at all possible. Use
12330 mod_status to see current server snapshot.
12332 *) (set_file_slot): New function, allowing auth directives to be
12333 independent of the server root, so the server documents can be
12334 moved to a different directory or machine more easily.
12335 [David J. MacKenzie]
12337 *) If no TransferLog is given explicitly, decline
12338 to log. This supports coexistence with other logging modules,
12339 such as the custom one that UUNET uses. [David J. MacKenzie]
12341 *) Check for titles in server-parsed HTML files.
12342 Ignore leading newlines and returns in titles. The old behavior
12343 of replacing a newline after <title> with a space causes the
12344 title to be misaligned in the listing. [David J. MacKenzie]
12346 *) Change mod_cern_meta to be configurable on a per-directory basis.
12347 [David J. MacKenzie]
12349 *) Add 'Include' directive to allow inclusion of configuration
12350 files within configuration files. [Randy Terbush]
12352 *) Proxy errors on connect() are logged to the error_log (nothing
12353 new); now they include the IP address and port that failed
12354 (*that's* new). [Ken Coar, Marc Slemko] PR#352
12356 *) Various architectures now define USE_MMAP_FILES which causes
12357 the server to use mmap() for static files. There are two
12358 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
12359 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
12360 number of bytes written in one cycle from a single mmap()d object,
12361 default 32768). [Dean Gaudet]
12363 *) API: Added post_read_request API phase which is run right after reading
12364 the request from a client, or right after an internal redirect. It is
12365 useful for modules setting environment variables that depend only on
12366 the headers/contents of the request. It does not run during subrequests
12367 because subrequests inherit pretty much everything from the main
12368 request. [Dean Gaudet]
12370 *) Added mod_unique_id which is used to generate a unique identifier for
12371 each hit, available in the environment variable UNIQUE_ID.
12374 *) init_modules is now called after the error logs have been opened. This
12375 allows modules to emit information messages into the error logs.
12378 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
12379 information for case where proxy module is not available. [Marc Slemko]
12381 *) PORT: Apache has need for mutexes to serialize its children around
12382 accept. In prior versions either fcntl file locking or flock file
12383 locking were used. The method is chosen by the definition of
12384 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
12385 and FLOCK for flock(). New options have been added:
12386 - SYSVSEM to use System V style semaphores
12387 - PTHREAD to use POSIX threads (appears to work on Solaris only)
12388 - USLOCK to use IRIX uslock
12389 Based on timing various techniques, the following changes were made
12391 - Linux 2.x uses flock instead of fcntl
12392 - Solaris 2.x uses pthreads
12393 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
12394 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
12395 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
12396 Martijn Koster <m.koster pobox.com>]
12398 *) PORT: The semantics of accept/select make it very desirable to use
12399 mutexes to serialize accept when multiple Listens are in use. But
12400 in the case where only a single socket is open it is sometimes
12401 redundant to serialize accept(). Not all unixes do a good job with
12402 potentially dozens of children blocked on accept() on the same
12403 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
12404 the server will avoid serialization when listening on only one socket,
12405 and use serialization when listening on multiple sockets.
12406 [Dean Gaudet] PR#467
12408 *) Configure changes: TestLib replaced by TestCompile, which has
12409 some additional capability (such as doing a sanity check of
12410 the compiler and flags selected); the version of Solaris is now
12411 available via the #define value of SOLARIS2; IRIX n32bit libs
12412 now supported and selectable by new Configuration Rule: IRIXN32;
12413 We no longer default to -O2 optimization. [Jim Jagielski]
12415 *) Updated Configure: Configuration now uses AddModule to specify
12416 module source or binary file location, relative to src directory.
12417 Modules can be dropped into modules/extra, or in their own
12418 directory, and modules can come with a Makefile or Configure can
12419 create one. Modules can add compiler or library information to
12420 generated Makefiles. [Paul Sutton]
12422 *) Source core re-organisation: distributed modules are now in
12423 modules/standard. All other source code is in main. OS-specific
12424 code is in os/{unix,emx,win32} directories. [Paul Sutton]
12426 *) mod_browser has been removed, since it's replaced by mod_setenvif.
12429 *) Fix another long-standing bug in sub_req_lookup_file where it would
12430 happily skip past access checks on subdirectories looked up with
12431 relative paths. (It's used by mod_dir, mod_negotiation,
12432 and mod_include.) [Dean Gaudet]
12434 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
12435 N is the number of <Directory> sections, and M is the number of
12436 components in the filename of an object.
12438 To achieve this optimization the following config changes were made:
12439 - Wildcards (* and ?, not the regex forms) in <Directory>s,
12440 <Files>s, and <Location>s now treat a slash as a special
12441 character. For example "/home/*/public_html" previously would
12442 match "/home/a/andrew/public_html", now it only matches things
12443 like "/home/bob/public_html". This mimics /bin/sh behaviour.
12444 - It's possible now to use [] wildcarding in <Directory>, <Files>
12446 - Regex <Directory>s are applied after all non-regex <Directory>s.
12450 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
12451 and corrupted paths. [Dean Gaudet]
12453 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
12454 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
12455 be accessed now via backreferences $1..$9 in RewriteConds test-against
12456 strings in addition to RewriteRules subst string. Second the grouped
12457 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
12458 via backreferences %1..%9 both in following RewriteCond test-against
12459 strings and RewriteRules subst string. This provides maximum flexibility
12460 through the use of backreferences.
12461 Additionally the rewriting engine was cleaned up by putting common
12462 code to the new expand_backrefs_inbuffer() function.
12463 [Ralf S. Engelschall]
12465 *) When merging the main server's <Directory> and <Location> sections into
12466 a vhost, put the main server's first and the vhost's second. Otherwise
12467 the vhost can't override the main server. [Dean Gaudet] PR#717
12469 *) The <Directory> code would merge and re-merge the same section after
12470 a match was found, possibly causing problems with some modules.
12473 *) ip-based vhosts are stored and queried using a hashing function, which
12474 has been shown to improve performance on servers with many ip-vhosts.
12475 Some other changes had to be made to accommodate this:
12476 - the * address for vhosts now behaves like _default_
12477 - the matching process now is:
12478 - match an ip-vhost directly via hash (possibly matches main
12480 - if that fails, just pretend it matched the main server
12481 - if so far only the main server has been matched, perform
12482 name-based lookups (ServerName, ServerAlias, ServerPath)
12483 *only on name-based vhosts*
12484 - if they fail, look for _default_ vhosts
12485 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
12487 *) dbmmanage overhaul:
12488 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
12489 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
12490 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
12491 - provide better seed for rand
12492 - prompt for password as per getpass(3) (turn off echo, read from
12494 - use "newstyle" crypt based on $Config{osname} ($^O)
12495 - will not add a user if already in database, use new `update' command
12497 - added `check' command to check a users' password
12498 - added `import' command to convert existing password text-files or
12499 dbm files exported with `view'
12500 - more descriptive usage, general cleanup, 'use strict' clean, etc.
12503 *) Added psocket() which is a pool form of socket(), various places within
12504 the proxy weren't properly blocking alarms while registering the cleanup
12505 for its sockets. bclose() now uses pclose() and pclosesocket(). There
12506 was a bug where the client socket was being close()d twice due a still
12507 registered cleanup. [Dean Gaudet]
12509 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
12512 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
12513 [Jason Venner <jason idiom.com>] PR#667
12515 *) Enable ``=""'' for RewriteCond directives to match against
12516 the empty string. This is the preferred way instead of ``^$''.
12517 [Ralf S. Engelschall]
12519 *) Fixed an infinite loop in mod_imap for references above the server root
12520 [Dean Gaudet] PR#748
12522 *) mod_proxy now has a ReceiveBufferSize directive, similar to
12523 SendBufferSize, so that the TCP window can be set appropriately
12524 for LFNs. [Phillip A. Prindeville]
12526 *) mod_browser has been replaced by the more general mod_setenvif
12527 (courtesy of Paul Sutton). BrowserMatch* directives are still
12528 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
12529 UnSetEnvIfZero directives. [Ken Coar]
12531 *) "HostnameLookups double" forces double-reverse DNS to succeed in
12532 order for remote_host to be set (for logging, or for the env var
12533 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
12536 *) mod_access overhaul:
12537 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
12538 and cidr syntax (i.e. 10.1.0.0/16). PR#762
12539 - Critical path was sped up by pre-computing a few things at config time.
12540 - The undocumented syntax "allow user-agents" was removed,
12541 the replacement is "allow from env=foobar" combined with mod_browser.
12542 - When used with hostnames it now forces a double-reverse lookup
12543 no matter what the directory settings are. This double-reverse
12544 doesn't affect any of the other routines that use the remote
12545 hostname. In particular it's still passed to CGIs and the log
12546 without the double-reverse check. Related PR#860.
12549 *) When a large bwrite() occurs (larger than the internal buffer size),
12550 while there is already something in the buffer, apache will combine
12551 the large write and the buffer into a single writev(). (This is
12552 in anticipation of using mmap() for reading files.)
12555 *) In obscure cases where a partial socket write occurred while chunking,
12556 Apache would omit the chunk header/footer on the next block. Cleaned
12557 up other bugs/inconsistencies in error conditions in buff.c. Fixed
12558 a bug where a long pause in DNS lookups could cause the last packet
12559 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
12561 *) API: Added child_exit function to module structure. This is called
12562 once per "heavy-weight process" just before a server child exit()'s
12563 e.g. when max_requests_per_child is reached, etc.
12564 [Doug MacEachern, Dean Gaudet]
12566 *) mod_include cleanup showed that handle_else was being used to handle
12567 endif. It didn't cause problems, but it was cleaned up too.
12570 *) mod_cern_meta would attempt to find meta files for the directory itself
12571 in some cases, but not in others. It now avoids it in all cases.
12574 *) mod_mime_magic would core dump if there was a decompression error.
12575 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
12577 *) PORT: some variants of DGUX require -lsocket -lnsl
12578 [Alexander L Jones <alex systems-options.co.uk>] PR#732
12580 *) mod_autoindex now allows sorting of FancyIndexed directory listings
12581 by the various fields (name, size, et cetera), either in ascending
12582 or descending order. Just click on the column header. [Ken Coar]
12584 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
12585 CPUs like the Alpha. Apache still stores ints in pointers, but that's
12586 the relatively safe direction. [Dean Gaudet] PR#344
12588 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
12589 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
12591 *) child_main avoids an unneeded call to select() when there is only one
12592 listening socket. [Dean Gaudet]
12594 *) In the event that the server is starved for idle servers it will
12595 spawn 1, then 2, then 4, ..., then 32 servers each second,
12596 doubling each second. It'll also give a warning in the errorlog
12597 since the most common reason for this is a poor StartServers
12598 setting. The define MAX_SPAWN_RATE can be used to raise/lower
12599 the maximum. [Dean Gaudet]
12601 *) Apache now provides an effectively unbuffered connection for
12602 CGI scripts. This means that data will be sent to the client
12603 as soon as the CGI pauses or stops output; previously, Apache would
12604 buffer the output up to a fixed buffer size before sending, which
12605 could result in the user viewing an empty page until the CGI finished
12606 or output a complete buffer. It is no longer necessary to use an
12607 "nph-" CGI to get unbuffered output. Given that most CGIs are written
12608 in a language that by default does buffering (e.g. perl) this
12609 shouldn't have a detrimental effect on performance.
12611 "nph-" CGIs, which formerly provided a direct socket to the client
12612 without any server post-processing, were not fully compatible with
12613 HTTP/1.1 or SSL support. As such they would have had to implement
12614 the transport details, such as encryption or chunking, in order
12615 to work properly in certain situations. Now, the only difference
12616 between nph and non-nph scripts is "non-parsed headers".
12617 [Dean Gaudet, Sameer Parekh, Roy Fielding]
12619 *) If a BUFF is switched from buffered to unbuffered reading the first
12620 bread() will return whatever remained in the buffer prior to the
12621 switch. [Dean Gaudet]
12623 Changes with Apache 1.3a1
12625 *) Added another Configure helper script: TestLib. It determines
12626 if a specified library exists. [Jim Jagielski]
12628 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
12629 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
12632 *) PORT: Some architectures use size_t for various lengths in network
12633 functions such as accept(), and getsockname(). The definition
12634 NET_SIZE_T is used to control this. [Dean Gaudet]
12636 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
12637 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
12638 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
12640 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
12641 [Igor N Kovalenko <infoh mail.wplus.net>]
12643 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
12644 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
12645 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
12646 [Dean Gaudet] related PR#875
12648 *) API: Correct child_init() slot declaration from int to void, to
12649 match the init() declaration. Update mod_example to use the new
12652 *) added transport handle slot (t_handle) to the BUFF structure
12655 *) get_client_block() returns wrong length if policy is
12656 REQUEST_CHUNKED_DECHUNK.

12664 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
12666 *) AddModuleInfo directive for mod_info which allows you to annotate
12667 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
12669 *) Added NoProxy directive to avoid using ProxyRemote for selected
12670 addresses. Added ProxyDomain directive to cause unqualified
12671 names to be qualified by redirection.
12672 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
12674 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
12675 header to the remote host in the proxy. [Sameer Parekh and
12678 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
12679 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
12680 URLs, fixed rewritelog(), fixed forced response code handling on
12681 redirects from within .htaccess files, disabled pipe locking under
12682 braindead SunOS 4.1.x, allow env variables to be set even on rules with
12683 no substitution, bugfixed situations where HostnameLookups is off, made
12684 mod_rewrite more thread-safe for NT port and fixed problem when creating
12685 an empty query string via "xxx?".
12686 This update also removes the copyright of Ralf S. Engelschall,
12687 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
12688 exclusively copyrighted by the Apache Group now. This happened because
12689 the author now has gifted mod_rewrite exclusively to the Apache Group and
12690 no longer maintains an external version.
12691 [Ralf S. Engelschall]
12693 *) API: Added child_init function to module structure. This is called
12694 once per "heavy-weight process" before any requests are handled.
12695 See http_config.h for more details. [Dean Gaudet]
12697 *) Anonymous_LogEmail was logging on each subrequest.
12698 [Dean Gaudet] PR#421, 868
12700 *) API: Added is_initial_req() which tests if the request being
12701 processed is the initial request, or a subrequest.
12704 *) Extended SSI (mod_include) now handles additional relops for
12705 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
12707 *) Configure fixed to correctly propagate user-selected options and
12708 settings (such as CC and OPTIM) to Makefiles other than
12709 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
12711 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
12712 directory indices to start with the contents of the HeaderName file
12713 if there is one. If there isn't one, the behaviour is unchanged.
12714 [Ken Coar, Roy Fielding, Andrey A. Chernov]
12716 *) WIN32: Modules can now be dynamically loaded DLLs using the
12717 LoadModule/LoadFile directives. Note that module DLLs must be
12718 compiled with the multithreaded DLL version of the runtime library.
12719 [Alexei Kosut and Ben Laurie]
12721 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
12722 This allows the admin to completely remove automatic indexing
12723 from the server, while still supporting the basic functions of
12724 trailing-slash redirects and DirectoryIndex files. Note that if
12725 you're carrying over an old Configuration file and you use directory
12726 indexing then you'll want to add:
12728 Module autoindex_module mod_autoindex.o
12730 before mod_dir in your Configuration. [Dean Gaudet]
12732 *) popendir/pclosedir created to properly protect directory scanning.
12733 [Dean Gaudet] PR#525
12735 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
12736 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
12737 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
12740 *) The AccessFileName directive can now take more than one filename.
12741 ["Lou D. Langholtz" <ldl usi.utah.edu>]
12743 *) The new mod_mime_magic can be used to "magically" determine the type
12744 of a file if the extension is unknown. Based on the unix file(1)
12745 command. [Ian Kluft <ikluft cisco.com>]
12747 *) We now determine and display the time spent processing a
12748 request if desired. [Jim Jagielski]
12750 *) mod_status: PID field of "dead" child slots no longer displays
12751 main httpd process's PID. [Jim Jagielski]
12753 *) Makefile.nt added - to build all the bits from the command line:
12754 nmake -f Makefile.nt
12755 Doesn't yet work properly. [Ben Laurie]
12757 *) Default text of 404 error is now "Not Found" rather than the
12758 potentially misleading "File Not Found". [Ken Coar]
12760 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
12761 for the net if we require people that actually need this data to
12762 enable it. [Linus Torvalds]
12764 *) directory_walk() is an expensive function, keep a little more state to
12765 avoid needless string counting. Add two new functions make_dirstr_parent
12766 and make_dirstr_prefix which replace all existing uses of make_dirstr.
12767 The new functions are a little less general than make_dirstr, but
12768 work more efficiently (less memory, less string counting).
12771 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
12772 to LDFLAGS) to avoid complications with lex rules in make files.
12773 [Dean Gaudet] PR#372
12775 *) run_method optimized to avoid needless scanning over NULLs in the
12776 module list. [Dean Gaudet]
12778 *) Revamp of (unix) scoreboard management code such that it avoids
12779 unnecessary traversals of the scoreboard on each hit. This is
12780 particularly important for high volume sites with a large
12781 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
12782 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
12783 httpd.h. [Dean Gaudet]
12785 *) In configurations using multiple Listen statements it was possible for
12786 busy sockets to starve other sockets of service. [Dean Gaudet]
12788 *) Added hook so standalone_main can be replaced at compile time
12789 (define STANDALONE_MAIN)
12792 *) Lowest-level read/write functions in buff.c will be replaced with
12793 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
12794 compile time. The default sfio discipline will behave as apache
12795 would without sfio compiled in.
12798 *) Enhance UserDir directive (mod_userdir) to accept a list of
12799 usernames for the 'disable' keyword, and add 'enable user...' to
12800 selectively *en*able userdirs if they're globally disabled.
12803 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
12804 will work with Netscape dbm files. (dbmmanage will probably not
12805 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
12807 *) Add a ListenBacklog directive to control the backlog parameter
12808 passed to listen(). Also change the default to 511 from 512.
12811 *) API: A new handler response DONE which informs apache that the
12812 request has been handled and it can finish off quickly, similar to
12813 how it handles errors. [Rob Hartill]
12815 *) Turn off chunked encoding after sending terminating chunk/footer
12816 so that we can't do it twice by accident. [Roy Fielding]
12818 *) mod_expire also issues Cache-Control: max-age headers.
12821 *) API: Added kill_only_once option for free_proc_chain so that it won't
12822 aggressively try to kill off specific children. For fastcgi.
12823 [Stanley Gambarin <gambarin OpenMarket.com>]
12825 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
12827 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
12828 When used together, these cause mod_dir to emit HEIGHT and WIDTH
12829 attributes in the FancyIndexing IMG tags. [Ken Coar]
12831 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
12833 *) PORT: Added Windows NT support
12834 [Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
12836 Changes with Apache 1.2.6
12838 *) mod_include when using XBitHack Full would send ETags in addition to
12839 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
12840 [Dean Gaudet] PR#1133
12842 *) SECURITY: When a client connects to a particular port/addr, and
12843 gives a Host: header ensure that the virtual host requested can
12844 actually be reached via that port/addr. [Ed Korthof <ed organic.com>]
12846 *) Support virtual hosts with wildcard port and/or multiple ports
12847 properly. [Ed Korthof <ed organic.com>]

12929 properly null terminated. [Marc Slemko]
12931 *) SECURITY: General mod_include cleanup, including fixing several
12932 possible buffer overflows and a possible infinite loop. This cleanup
12933 was done against 1.3 code and then backported to 1.2, the result
12934 is a large difference (due to indentation cleanup in 1.3 code).
12935 Users interested in seeing a smaller set of relevant differences
12936 should consider comparing against src/modules/standard/mod_include.c
12937 from the 1.3b3 release. Non-indentation changes to mod_include

13006 happily skip past access checks on subdirectories looked up with relative
13007 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)

13026 [Dean Gaudet] PR#748
13028 *) mod_include cleanup showed that handle_else was being used to handle
13029 endif. It didn't cause problems, but it was cleaned up too.
13032 *) Last official synchronization of mod_rewrite with author version (because
13033 mod_rewrite is now directly developed by the author at the Apache Group):
13034 o added diff between mod_rewrite 3.0.6+ and 3.0.9

13079 *) API: In HTTP/1.1, whether or not a request message contains a body
13080 is independent of the request method and based solely on the presence
13081 of a Content-Length or Transfer-Encoding. Therefore, our default
13082 handlers need to be prepared to read a body even if they don't know
13083 what to do with it; otherwise, the body would be mistaken for the
13084 next request on a persistent connection. discard_request_body()
13085 has been added to take care of that. [Roy Fielding] PR#378

13105 (headers, readmes, titles), mod_negotiation (type maps), or
13106 mod_cern_meta (meta files). [Dean Gaudet]
13108 *) SECURITY: Apache will refuse to run as "User root" unless
13109 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
13111 *) CONFIG: If a symlink pointed to a directory then it would be disallowed

13136 solaris libc). On all systems apache attempts to keep all permanent
13137 descriptors above 15 (called the low slack line). Solaris users
13138 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
13139 which keeps all non-FILE * descriptors above 255. On all systems
13140 this should make supporting large numbers of vhosts with many open
13141 log files more feasible. If this causes trouble please report it,
13142 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.

13253 we don't want the error message to include those fields. Likewise,

13276 *) The method for determining PATH_INFO has been restored to the pre-1.2b
13277 (and NCSA httpd) definition wherein it was the extra path info beyond
13278 the CGI script filename. The environment variable FILEPATH_INFO has
13279 been removed, and instead we supply the original REQUEST_URI to any
13280 script that wants to be Apache-specific and needs the real URI path.
13281 This solves a problem with existing scripts that use extra path info
13282 in the ScriptAlias directive to pass options to the CGI script.

13286 that use multiple Listen statements for listening on multiple ports.
13287 But that change is necessary to make _default_ consistent with other

13364 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
13365 object that can't be PUT, or FOOBAR for some method FOOBAR that
13366 apache doesn't know about at all). Log 404s that occur in mod_include.
13367 [Paul Sutton, John Van Essen]
13369 *) If a soft timeout (or lingerout) occurs while trying to flush a
13370 buffer or write inside buff.c or fread'ing from a CGI's output,
13371 then the timeout would be ignored. [Roy Fielding] PR#373
13373 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
13374 parsing of headers. If the terminating empty-line CRLF occurs starting
13375 at the 256th or 257th byte of output, then Navigator will think a normal
13376 image is invalid. We are guessing that this is because their initial
13377 read of a new request uses a 256 byte buffer. We check the bytes written
13378 so far and, if we are about to tickle the bug, we instead insert a
13379 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
13381 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
13382 of an external redirection. [Roy Fielding and Paul Sutton]
13384 *) Configure would create a broken Makefile if the configuration file
13385 contained a commented-out Rule. [Roy Fielding]
13387 *) Promote per_dir_config and subprocess_env from the subrequest to the
13388 main request in mod_negotiation. In particular this fixes a bug
13389 where <Files> sections wouldn't properly apply to negotiated content.
13392 *) Fix a potential deadlock in mod_cgi script_err handling.
13393 [Ralf S. Engelschall]
13395 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
13396 [Mitchell Blank Jr]
13398 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
13399 .htaccess files because the RewriteBase was not replaced correctly.
13400 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
13401 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
13403 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
13404 1.x the settings are those of pre-1.2b8. For 2.x we include
13405 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
13406 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
13407 [Dean Gaudet] PR#336, PR#340
13409 *) Redirect did not preserve ?query_strings when present in the client's
13410 request. [Dean Gaudet]
13412 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
13414 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
13416 *) Add UnixWare compile/install instructions. [Chuck Murcko]
13418 *) Add mod_example (illustration of API techniques). [Ken Coar]
13420 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
13422 *) Improve handling of directories when filenames have spaces in them.
13425 *) For hosts with multiple IP addresses, try all additional addresses if
13426 necessary to get a connect. Fail only if hostent address list is
13427 exhausted. [Chuck Murcko]
13429 *) More signed/unsigned port fixes. [Dean Gaudet]
13431 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
13434 Changes with Apache 1.2b8
13436 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
13437 to it. [Marc Slemko]
13439 *) The addition of <Location> and <File> directives made the
13440 sub_req_lookup_simple() function bogus, so we now handle
13441 the special cases directly. [Dean Gaudet]
13443 *) We now try to log where the server is dumping core when a fatal
13444 signal is received. [Ken Coar]
13446 *) Improved lingering_close by adding a special timeout, removing the
13447 spurious log messages, removing the nonblocking settings (they
13448 are not needed with the better timeout), and adding commentary
13449 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
13450 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
13452 *) Send error messages about setsockopt failures to the server error
13453 log instead of stderr. [Roy Fielding]
13455 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
13457 *) Stopgap solution for CGI 3-second delay with server-side includes: if
13458 processing a subrequest, allocate memory from r->main->pool instead
13459 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
13460 in the middle of an SSI request. [Dean Gaudet] PR #122
13462 *) Fixed status of response when POST is received for a nonexistent URL
13463 (was sending 405, now 404) and when any method is sent with a
13464 full-URI that doesn't match the server and the server is not acting
13465 as a proxy (was sending 501, now 403). [Roy Fielding]
13467 *) Host port changed to unsigned short. [Ken Coar] PR #276
13469 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
13471 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
13473 *) Report extra info from errno with many errors that cause httpd to exit.
13474 spawn_child, popenf, and pclosef now have valid errno returns in the
13475 event of an error. Correct problems where errno was stomped on
13476 before being reported. [Dean Gaudet]
13478 *) In the proxy, if the cache filesystem was full, garbage_coll() was
13479 never called, and thus the filesystem would remain full indefinitely.
13480 We now also remove incomplete cache files left if the origin server
13481 didn't send a Content-Length header and either the client has aborted
13482 transfer or bwrite() to client has failed. [Petr Lampa]
13484 *) Fixed the handling of module and script-added header fields.
13485 Improved the interface for sending header fields and reduced
13486 the duplication of code between sending okay responses and errors.
13487 We now always send both headers_out and err_headers_out, and
13488 ensure that the server-reserved fields are not being overridden,
13489 while not overriding those that are not reserved. [Roy Fielding]
13491 *) Moved transparent content negotiation fields to err_headers_out
13492 to reflect above changes. [Petr Lampa]
13494 *) Fixed the determination of whether or not we should make the
13495 connection persistent for all of the cases where some other part
13496 of the server has already indicated that we should not. Also
13497 improved the ordering of the test so that chunked encoding will
13498 be set whenever it is desired instead of only when KeepAlive
13499 is enabled. Added persistent connection capability for most error
13500 responses (those that do not indicate a bad input stream) when
13501 accessed by an HTTP/1.1 client. [Roy Fielding]
13503 *) Added missing timeouts for sending header fields, error responses,
13504 and the last chunk of chunked encoding, each of which could have
13505 resulted in a process being stuck in write forever. Using soft_timeout
13506 requires that the sender check for an aborted connection rather than
13507 continuing after an EINTR. Timeouts that used to be initiated before
13508 send_http_header (and never killed) are now initiated only within or
13509 around the routines that actually do the sending, and not allowed to
13510 propagate above the caller. [Roy Fielding]
13512 *) mod_auth_anon required an @ or a . in the email address, not both.
13515 *) per_dir_defaults weren't set correctly until directory_walk for
13516 name-based vhosts. This fixes an obscure bug with the wrong config
13517 info being used for vhosts that share the same ip as the server.
13520 *) Improved generation of modules/Makefile to be more generic for
13521 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
13523 *) Generate makefile dependency for Configuration based on the actual
13524 name given when running the Configure process. [Dean Gaudet]
13526 *) Fixed problem with vhost error log not being set prior to
13527 initializing virtual hosts. [Dean Gaudet]
13529 *) Fixed infinite loop when a trailing slash is included after a type map
13530 file URL (extra path info). [Petr Lampa]
13532 *) Fixed server status updating of per-connection counters. [Roy Fielding]
13534 *) Add documentation for DNS issues (reliability and security), and try
13535 to explain the virtual host matching process. [Dean Gaudet]
13537 *) Try to continue gracefully by disabling the vhost if a DNS lookup
13538 fails while parsing the configuration file. [Dean Gaudet]
13540 *) Improved calls to setsockopt. [Roy Fielding]
13542 *) Negotiation changes: Don't output empty content-type in variant list;
13543 Output charset in variant list; Return sooner from handle_multi() if
13544 no variants found; Add handling of '*' wildcard in Accept-Charset.
13545 [Petr Lampa and Paul Sutton]
13547 *) Fixed overlaying of request/sub-request notes and headers in
13548 mod_negotiation. [Dean Gaudet]
13550 *) If two variants' charset quality are equal and one is the default
13551 charset (iso-8859-1), then prefer the variant that was specifically
13552 listed in Accept-Charset instead of the default. [Petr Lampa]
13554 *) Memory allocation problem in push_array() -- it would corrupt memory
13555 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
13557 *) invoke_handler() doesn't handle mime arguments in content-type
13558 [Petr Lampa] PR#160
13560 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
13563 *) Fixed problem with ErrorDocument not working for virtual hosts
13564 due to one of the performance changes in 1.2b7. [Dean Gaudet]
13566 *) Log an error message if we get a request header that is too long,
13567 since it may indicate a buffer overflow attack. [Marc Slemko]
13569 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
13570 not reject URLs without a double-slash, as per RFC2068 section 3.2.
13571 [Ken Coar] PR #146, #187
13573 *) Added table entry placeholder for new header_parser callback
13574 in all of the distributed modules. [Ken Coar] PR #191
13576 *) Allow for cgi files without the .EXE extension on them under OS/2.
13577 [Garey Smiley] PR #59
13579 *) Fixed error message when resource is not found and URL contains
13580 path info. [Petr Lampa and Dean Gaudet] PR #40
13582 *) Fixed user and server confusion over what should be a virtual host
13583 and what is the main server, resulting in access to something
13584 other than the name defined in the virtualhost directive (but
13585 with the same IP address) failing. [Dean Gaudet]
13587 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
13588 AIX; improves the redirection stuff to enable the users to generally
13589 redirect to http, https, gopher and ftp; added TIME variable for
13590 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
13591 special patterns >STRING, <STRING and =STRING to RewriteCond, which
13592 can be used in conjunction with %{TIME} or other variables to create
13593 time-dependent rewriting rules. [Ralf S. Engelschall]
13595 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
13596 Module authors may need to adjust their code for proper cleanup to take
13597 place (that is, call note_cleanups_for_fd()). This change fixes problems
13598 with file descriptors being erroneously closed when the proxy module was
13599 in use. [Ben Laurie]
13601 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
13602 initgroups() to hose the group information needed for later
13603 comparisons. [Randy Terbush]
13605 *) Remove unnecessary call to va_end() in create_argv() which
13606 caused a SEGV on some systems.
13608 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
13611 *) Clear memory allocated for listeners. [Randy Terbush]
13613 *) Improved handling of IP address as a virtualhost address and
13614 introduced "_default_" as a synonym for the default vhost config.
13615 [Dean Gaudet] PR #212
13617 Changes with Apache 1.2b7
13619 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
13621 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
13623 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
13624 - replace protocol response numbers with symbols
13625 - save variant-list into main request notes
13626 - free allocated memory from subrequests
13627 - merge notes, headers_out and err_headers_out
13629 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
13630 "HTTP/#.# ###*" to be more lenient about what we accept.
13633 *) more proxy FTP bug fixes:
13634 - Changed send_dir() to remove user/passwd from displayed URL.
13635 - Changed login error messages to be more descriptive.
13636 - remove setting of SO_DEBUG socket option
13637 - Make ftp_getrc() more lenient about multiline responses,
13638 specifically, 230 responses which don't have continuation 230-
13639 on each line). These seem to be all NT FTP servers, and while
13640 perhaps questionable, they appear to be legal by RFC 959.
13641 - Add missing kill_timeout() after transfer to user completes.
13644 *) Fixed problem where a busy server could hang when restarting
13645 after being sent a SIGHUP due to child processes not exiting.
13648 *) Modify mod_include escaping so a '\' only signifies an escaped
13649 character if the next character is one that needs
13650 escaping. [Ben Laurie]
13652 *) Eliminated possible infinite loop in mod_imap when relative URLs are
13653 used with a 'base' directive that does not have a '/' in it.
13654 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
13656 *) Reduced the default timeout from 1200 seconds to 300, and the
13657 one in the sample configfile from 400 to 300. [Marc Slemko]
13659 *) Stop vbprintf from crashing if given a NULL string pointer;
13660 print (null) instead. [Ken Coar]
13662 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
13663 [Marc Slemko and Roy Fielding]
13665 *) Fixed problem with mod_cgi-generated internal redirects trying to
13666 read the request message-body twice. [Archie Cobbs and Roy Fielding]
13668 *) Reduced timeout on lingering close, removed possibility of a blocked
13669 read causing the child to hang, and stopped logging of errors if
13670 the socket is not connected (reset by client). [Roy Fielding]
13672 *) Rearranged main child loop to remove duplication of code in
13673 select/accept and keep-alive requests, fixed several bugs regarding
13674 checking scoreboard_image for exit indication and failure to
13675 account for all success conditions and trap all error conditions,
13676 prevented multiple flushes before closing the socket; close the entire
13677 socket buffer instead of just one descriptor, prevent logging of
13678 EPROTO and ECONNABORTED on platforms where supported, and generally
13679 improved readability. [Roy Fielding]
13681 *) Extensive performance improvements. Cleaned up inefficient use of
13682 auto initializers, multiple is_matchexp calls on a static string,
13683 and excessive merging of response_code_strings. [Dean Gaudet]
13685 *) Added double-buffering to mod_include to improve performance on
13686 server-side includes. [Marc Slemko]
13688 *) Several fixes for suexec wrapper. [Randy Terbush]
13689 - Make wrapper work for files on NFS filesystem.
13690 - Fix portability problem of MAXPATHLEN.
13691 - Fix array overrun problem in clean_env().
13692 - Fix allocation of PATH environment variable
13694 *) Removed extraneous blank line is description of mod_status chars.
13697 *) Logging of errors from the call_exec routine simply went nowhere,
13698 since the logfile fd has been closed, so now we send them to stderr.
13699 [Harald T. Alvestrand]
13701 *) Fixed core dump when DocumentRoot is a CGI.
13702 [Ben Laurie, reported by <geddis tesserae.com>]
13704 *) Fixed potential file descriptor leak in mod_asis; updated it and
13705 http_core to use pfopen/pfclose instead of fopen/fclose.
13706 [Randy Terbush and Roy Fielding]
13708 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
13709 as the DEC Alpha which is 64-bit but uses 32-bit ints.
13710 [Dean Gaudet and Ken Coar]
13712 *) Return a 302 response code to the client when sending a redirect
13713 due to a missing trailing '/' on a directory instead of a 301; now
13714 it is cacheable. [Markus Gyger]
13716 *) Fix condition where, if a bad directive occurs in .htaccess, and
13717 sub_request() goes first to this directory, then log_reason() will
13718 SIGSEGV because it doesn't have initialized r->per_dir_config.
13719 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
13721 *) Fix handling of lang_index in is_variant_better(). This was
13722 causing problems which resulted in the server sending the
13723 wrong language document in some cases. [Petr Lampa]
13725 *) Remove free() from clean_env() in suexec wrapper. This was nuking
13726 the clean environment on some systems.
13728 *) Tweak byteserving code (e.g. serving PDF files) to work around
13729 bugs in Netscape Navigator and Microsoft Internet Explorer.
13730 Emit Content-Length header when sending multipart/byteranges.
13733 *) Port to HI-UX/WE2. [Nick Maclaren]
13735 *) Port to HP MPE operating system for HP 3000 machines
13736 [Mark Bixby <markb cccd.edu>]
13738 *) Fixed bug which caused a segmentation fault if only one argument
13739 given to RLimit* directives. [Ed Korthof]
13741 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
13743 *) Improved buffered output to the client by delaying the flush decision
13744 until the BUFF code is actually about to read the next request.
13745 This fixes a problem introduced in 1.2b5 with clients that send
13746 an extra CRLF after a POST request. Also improved chunked output
13747 performance by combining writes using writev() and removing as
13748 many bflush() calls as possible. NOTE: Platforms without writev()
13749 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
13750 or Configure, unless we have already done so. [Dean Gaudet]
13752 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
13754 *) Fixed mod_info output corruption bug introduced by buffer overflow
13755 fixes. [Dean Gaudet]
13757 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
13758 for the special case of a 304 response. [Paul Sutton]
13760 *) Improved handling of TRACE method by bypassing normal method handling
13761 and header parsing routines; fixed Allow response to always allow TRACE.
13764 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
13766 *) Cleaned-up some of the generated HTML. [Ken Coar]
13768 Changes with Apache 1.2b6
13770 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
13772 *) Fix typo introduced in fix for potential infinite loop around
13773 accept() in child_main(). This change caused the rev to 1.2b6.
13774 1.2b5 was never a public beta.
13776 Changes with Apache 1.2b5
13778 *) Change KeepAlive semantics (On|Off instead of a number), add
13779 MaxKeepAliveRequests directive. [Alexei Kosut]
13781 *) Various NeXT compilation patches, as well as a change in
13782 regex/regcomp.c since that file also used a NEXT define.
13785 *) Allow * to terminate the end of a directory match in mod_dir.
13786 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
13788 *) Don't call can_exec() if suexec_enabled. Calling this requires
13789 scripts executed by the suexec wrapper to be world executable, which
13790 defeats one of the advantages of running the wrapper. [Randy Terbush]
13792 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
13795 *) Migration from sprintf() to snprintf() to avoid buffer
13796 overflows. [Marc Slemko]
13798 *) Provide portable snprintf() implementation (ap_snprintf)
13799 as well as *cvt family. [Jim Jagielski]
13801 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
13804 *) Remove mod_fastcgi.c from the distribution. This module appears
13805 to be maintained more through the Open Market channels and should
13806 continue to be easily available at http://www.fastcgi.com/
13808 *) Fixed bug in modules/Makefile that wouldn't allow building in more
13809 than one subdirectory (or cleaning, either). [Jeremy Laidman]
13811 *) mod_info assumed that the config files were relative to ServerRoot.
13814 *) CGI scripts called as an error document resulting from failed
13815 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
13817 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
13820 *) Properly check errno to prevent display of a directory index
13821 when server receives a long enough URL to confuse stat().
13824 *) Several security enhancements to suexec wrapper. It is _highly_
13825 recommended that previously installed versions of the wrapper
13826 be replaced with this version. [Randy Terbush, Jason Dour]
13828 - ~user execution now properly restricted to ~user's home
13829 directory and below.
13830 - execution restricted to UID/GID > 100
13831 - restrict passed environment to known variables
13832 - call setgid() before initgroups() (portability fix)
13833 - remove use of setenv() (portability fix)
13835 *) Add HTTP/1.0 response forcing. [Ben Laurie]
13837 *) Add access control via environment variables. [Ben Laurie]
13839 *) Add rflush() function. [Alexei Kosut]
13841 *) remove duplicate pcalloc() call in new_connection().
13843 *) Fix incorrect comparison which could allow number of children =
13844 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
13845 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
13847 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
13848 AIX PS/2, CONVEXOS. [Jim Jagielski]
13850 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
13851 It's more portable. [Martin Kraemer]
13853 *) Replace references to make in Makefile.tmpl with $(MAKE).
13856 *) Add ProxyBlock directive w/IP address caching. Add IP address
13857 caching to NoCache directive as well. ProxyBlock works with all
13858 handlers; NoCache now also works with FTP for anonymous logins.
13859 Still more code cleanup. [Chuck Murcko]
13861 *) Add "header parse" API hook [Ben Laurie]
13863 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
13865 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
13867 *) Correctly allow access and auth directives in <Files> sections in
13868 server config files. [Alexei Kosut]
13870 *) Fix bug with ServerPath that could cause certain files to be not
13871 found by the server. [Alexei Kosut]
13873 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
13874 double-quote from text and so that it properly checks for unsupported
13875 status codes using the new index_of_response interface. [Roy Fielding]
13877 *) Multiple fixes to the lingering_close code in order to avoid being
13878 interrupted by a stray timeout, to avoid lingering on a connection
13879 that has already been aborted or never really existed, to ensure that
13880 we stop lingering as soon as any error condition is received, and to
13881 prevent being stuck indefinitely if the read blocks. Also improves
13882 reporting of error conditions. [Marc Slemko and Roy Fielding]
13884 *) Fixed initialization of parameter structure for sigaction.
13885 [<mgyger itr.ch>, Adrian Filipi-Martin]
13887 *) Fixed reinitializing the parameters before each call to accept and
13888 select, and removed potential for infinite loop in accept.
13889 [Roy Fielding, after useful PR from <adrian virginia.edu>]
13891 *) Fixed condition where, if a child fails to fork, the scoreboard would
13892 continue to say SERVER_STARTING forever. Eventually, the main process
13893 would refuse to start new children because count_idle_servers() will
13894 count those SERVER_STARTING entries and will always report that there
13895 are enough idle servers. [Phillip Vandry]
13897 *) Fixed bug in bcwrite regarding failure to account for partial writes.
13898 Avoided calling bflush() when the client is pipelining requests.
13899 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
13901 *) Added description of "." mode in server-status [Jim Jagielski]
13903 Changes with Apache 1.2b4
13905 *) Fix possible race condition in accept_mutex_init() that
13906 could leave a small security hole open allowing files to be
13907 overwritten in cases where the server UID has write permissions.
13910 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
13912 *) Fix portablity problem in util_script where ARG_MAX may not be
13913 defined for some systems.
13915 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
13918 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
13919 style magic #! token for better script portability. [Garey Smiley]
13921 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
13922 execution for ~userdir CGI. [Jason Dour]
13924 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
13926 *) Fix month off by one in suexec wrapper logging.
13928 Changes with Apache 1.2b3:
13930 *) Fix error in mod_cgi which could cause resources not to be properly
13931 freed, or worse. [Dean Gaudet]
13933 *) Fix find_string() NULL pointer dereference. [Howard Fear]
13935 *) Add set_flag_slot() at the request of Dirk and others.
13938 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
13940 *) Add changes to improve the error message given for invalid
13941 ServerName parameters. [Dirk vanGulik]
13943 *) Add "Authoritative" directive for Auth modules that don't
13944 currently have it. This gives admin control to assign authoritative
13945 control to an authentication scheme and allow "fall through" for
13946 those authentication modules that aren't "Authoritative" thereby
13947 allowing multiple authentication mechanisms to be chained.
13950 *) Remove requirement for ResourceConfig/AccessConfig if not using
13951 the three config file layout. [Randy Terbush]
13953 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
13955 *) Changes to suexec wrapper to fix the following problems:
13956 1. symlinked homedirs will kill ~userdirs.
13957 2. initgroups() on Linux 2.0.x clobbers gr->grid.
13958 3. CGI command lines paramters problems
13959 4. pw-pwdir for "docroot check" still the httpd user's pw record.
13960 [Randy Terbush, Jason Dour]
13962 *) Change create_argv() to accept variable arguments. This fixes
13963 a problem where arguments were not getting passed to the CGI via
13964 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
13966 *) Collapse multiple slashes in path URLs to properly apply
13967 handlers defined by <Location>. [Alexei Kosut]
13969 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
13971 *) Improve the accuracy of request duration timings by setting
13972 r->request_time in read_request_line() instead of read_request().
13975 *) Reset timeout while reading via get_client_block() in mod_cgi.c
13976 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
13978 *) Add the ability to pass different Makefile.tmpl files to Configure
13979 using the -make flag. [Rob Hartill]
13981 *) Fix coredump triggered when sending a SIGHUP to the server caused
13982 by an assertion failure, in turn caused by an uninitialised field in a
13986 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
13987 PATH_INFO from previous versions of Apache (in certain situations,
13988 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
13989 [later removed in 1.2b11]
13991 *) Add rwrite() function to API to allow for sending strings of
13992 arbitrary length. [Doug MacEachern]
13994 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
13996 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
13997 NeXT. [Jim Jagielski]
13999 *) Removed recent modification to promote the status code on internal
14000 redirects, since the correct fix was to change the default log format
14001 in mod_log_config so that it outputs the original status. [Rob Hartill]
14003 Changes with Apache 1.2b2:
14005 *) Update set_signals() to use sigaction() for setting handlers.
14006 This appears to fix a re-entrant problem in the seg_fault()
14007 bus_error() handlers. [Randy Terbush]
14009 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
14011 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
14013 *) proxy_http.c bugfixes: [Chuck Murcko]
14014 1) fixes possible NULL pointer reference w/NoCache
14015 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
14016 host would cache nothing if it was in the local domain,
14017 and the local domain was in the NoCache list)
14018 3) Adds Host: header when not available
14019 4) Some code cleanup and clarification
14021 *) mod_include.c bugfixes:
14022 1) Fixed an ommission that caused include variables to not
14023 be parsed in config errmsg directives [Howard Fear]
14024 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
14025 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
14026 4) Allow backslash-escaping to all quoted text
14027 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
14028 5) Pass variable to command line if not set in XSSI's env
14031 *) Fix infinite loop when processing Content-language lines in
14032 type-map files. [Alexei Kosut]
14034 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
14036 *) Fixed problem in set_[user|group] that prevented CGI execution
14037 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
14039 *) Added PORTING information file. [Jim Jagielski]
14041 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
14043 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
14045 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
14046 USE_FCNTL_SERIALIZED_ACCEPT was intended.
14048 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
14049 which caused problems of systems where socket s_addr is >32bits.
14051 *) Added comment to explain (r->chunked = 1) side-effect in
14052 http_protocol.c [Roy Fielding]
14054 *) Replaced use of index() in mod_expires.c with more appropriate
14055 and portable isdigit() test. [Ben Laurie]
14057 *) Updated Configure for ...
14058 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
14059 *-dg-dgux* (bad pattern match)
14060 QNX (DEF_WANTHSREGEX=yes)
14061 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
14063 *-unixware211 (new)
14064 and added some user diagnostic info. [Ben Laurie]
14066 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
14067 for better portability. [Jim Jagielski]
14069 *) Updated helpers/GuessOS for ...
14070 SCO 5 (recognize minor releases)
14071 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
14072 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
14073 IRIX64 (-sgi-irix64)
14074 ULTRIX (-unknown-ultrix)
14075 SINIX (-whatever-sysv4)
14076 NCR Unix (-ncr-sysv4)
14077 and fixed something in helpers/PrintPath [Ben Laurie]
14079 Changes with Apache 1.2b1
14081 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
14083 Changes with Apache 1.1.1
14085 *) Fixed bug where Cookie module would make two entries in the
14086 logfile for each access [Mark Cox]
14088 *) Fixed bug where Redirect in .htaccess files would cause memory
14089 leak. [Nathan Neulinger]
14091 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
14093 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
14095 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
14097 Changes with Apache 1.1.0
14099 *) Bring NeXT support up to date. [Takaaki Matsumoto]
14101 *) Bring QNX support up to date. [Ben Laurie]
14103 *) Make virtual hosts default to main server keepalive parameters.
14104 [Alexei Kosut, Ben Laurie]
14106 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
14108 *) Fix missing address family for connect, also remove unreachable statement
14109 in mod_proxy. [Ben Laurie]
14111 *) mod_env now turned on by default in Configuration.tmpl.
14113 *) Bugs which were fixed:
14114 a) yet more mod_proxy bugs [Ben Laurie]
14115 b) CGI works again with inetd [Alexei Kosut]
14116 c) Leading colons were stripped from passwords [<osm interguide.com>]
14117 d) Another fix to multi-method Limit problem [<jk tools.de>]
14119 Changes with Apache 1.1b4
14121 *) r->bytes_sent variable restored. [Robert Thau]
14123 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
14125 *) More possibly unsecure programs removed from the support directory.
14127 *) More mod_auth_msql authentication improvements.
14129 *) VirtualHosts based on Host: headers no longer conflict with the
14132 *) OS/2 compatibility enhancements. [Gary Smiley]
14134 *) POST now allowed to directory index CGI scripts.
14136 *) Actions now work with files of the default type.
14138 *) Bugs which were fixed:
14139 a) more mod_proxy bugs
14140 b) early termination of inetd requests
14141 c) compile warnings on several systems
14142 d) problems when scripts stop reading output early
14144 Changes with Apache 1.1b3
14146 *) Much of cgi-bin and all of cgi-src has been removed, due to
14147 various security holes found and that we could no longer support
14150 *) The "Set-Cookie" header is now special-cased to not merge multiple
14151 instances, since certain popular browsers can not handle multiple
14152 Set-Cookie instructions in a single header. [Paul Sutton]
14154 *) rprintf() added to buffer code, occurrences of sprintf removed.
14157 *) CONNECT method for proxy module, which means tunneling SSL should work.
14158 (No crypto needed) Also a NoCache config directive.
14160 *) Several API additions: pstrndup(), table_unset() and get_token()
14161 functions now available to modules.
14163 *) mod_imap fixups, in particular Location: headers are now complete
14166 *) New "info" module which reports on installed module set through a
14167 special URL, a la mod_status.
14169 *) "ServerPath" directive added - allows for graceful transition
14170 for Host:-header-based virtual hosts.
14172 *) Anonymous authentication module improvements.
14174 *) MSQL authentication module improvements.
14176 *) Status module design improved - output now table-based. [Ben Laurie]
14178 *) htdigest utility included for use with digest authentication
14181 *) mod_negotiation: Accept values with wildcards to be treated with
14182 less priority than those without wildcards at the same quality
14183 value. [Alexei Kosut]
14185 *) Bugs which were fixed:
14186 a) numerous mod_proxy bugs
14187 b) CGI early-termination bug [Ben Laurie]
14188 c) Keepalives not working with virtual hosts
14189 d) RefererIgnore problems
14190 e) closing fd's twice in mod_include (causing core dumps on
14191 Linux and elsewhere).
14193 Changes with Apache 1.1b2
14196 a) core dumps in mod_digest
14197 b) truncated hostnames/ip address in the logs
14198 c) relative URL's in mod_imap map files
14200 Changes with Apache 1.1b1
14202 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
14204 Changes with Apache 1.0.3
14206 *) Internal redirects which occur in mod_dir.c now preserve the
14207 query portion of a request (the bit after the question mark).
14210 *) Escape active characters '<', '>' and '&' in html output in
14211 directory listings, error messages and redirection links.
14214 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
14216 *) Fix for POSIX compliance in waiting for processes in alloc.c.
14219 *) setsockopt no longer takes a const declared argument [Martijn Koster]
14221 *) Reset timeout timer after each successful fwrite() to the network.
14222 This patch adds a reset_timeout() procedure that is called by
14223 send_fd() to reset the timeout ever time data is written to the net.
14226 *) timeout() signal handler now checks for SIGPIPE and reports
14227 lost connections in a more user friendly way. [Rob Hartill]
14229 *) Location of the "scoreboard" file which used to live in /tmp is
14230 now configurable (for OSes that can't use mmap) via ScoreBoardFile
14231 which works similar to PidFile (in httpd.conf) [Rob Hartill]
14233 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
14235 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
14236 which caused a SEGV with cookies enabled
14238 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
14241 *) Log the UNIX textual error returned by some system calls, in
14242 particular errors from accept() [David Robinson]
14244 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
14246 Changes with Apache 1.0.2
14248 *) patch to get Apache compiled on UnixWare 2.x, recommended as
14249 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
14251 *) Fix get_basic_auth_pw() to set the auth_type of the request.
14254 *) past changes to http_config.c to only use the
14255 setrlimit function on systems defining RLIMIT_NOFILE
14256 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
14257 for SUNOS and prototypes the needed functions.
14259 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
14262 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
14264 *) Merge multiple headers from CGI scripts instead of taking last
14265 one. [David Robinson]
14267 *) Add support for SCO 5. [Ben Laurie]
14269 Changes with Apache 1.0.1
14271 *) Silence mod_log_referer and mod_log_agent if not configured
14274 *) Recursive includes can occur if the client supplies PATH_INFO data
14275 and the server provider uses relative links; as file.html
14276 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
14278 *) The replacement for initgroups() did not call {set,end}grent(). This
14279 had two implications: if anything else used getgrent(), then
14280 initgroups() would fail, and it was consuming a file descriptor.
14283 *) On heavily loaded servers it was possible for the scoreboard to get
14284 out of sync with reality, as a result of a race condition.
14285 The observed symptoms are far more Apaches running than should
14286 be, and heavy system loads, generally followed by catastrophic
14287 system failure. [Ben Laurie]
14289 *) Fix typo in license. [David Robinson]
14291 Changes with Apache 1.0.0 23 Nov 1995
14293 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
14295 Changes with Apache 0.8.16 05 Nov 1995
14297 *) New man page for 'httpd' added to support directory [David Robinson]
14299 *) .htgroup files can have more than one line giving members for a
14300 given group (each must have the group name in front), for NCSA
14301 back-compatibility [Robert Thau]
14303 *) Mutual exclusion around accept() is on by default for SVR4 systems
14304 generally, since they generally can't handle multiple processes in
14305 accept() on the same socket. This should cure flaky behavior on
14306 a lot of those systems. [David Robinson]
14308 *) AddType, AddEncoding, and AddLanguage directives take multiple
14309 extensions on a single command line [David Robinson]
14311 *) UserDir can be disabled for a given virtual host by saying
14312 "UserDir disabled" in the <VirtualHost> section --- it was a bug
14313 that this didn't work. [David Robinson]
14315 *) Compiles on QNX [Ben Laurie]
14317 *) Corrected parsing of ctime time format [David Robinson]
14319 *) httpd does a perror() before exiting if it can't log its pid
14320 to the PidFile, to make diagnosing the error a bit easier.
14323 *) <!--#include file="..."--> can no longer include files in the
14324 parent directory, for NCSA back-compatibility. [David Robinson]
14326 *) '~' is *not* escaped in URIs generated for directory listings
14329 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
14331 *) Fixed bug involving handling URIs with escaped %-characters
14332 in redirects [David Robinson]
14334 Changes with Apache 0.8.15 14 Oct 1995
14336 *) Switched to new, simpler license
14338 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
14340 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
14342 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
14344 *) Correctly handles internal redirects to files with names containing '%'
14347 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
14349 *) Use geteuid() rather than getuid() to see if we have root privilege,
14350 so that server correctly resets privilege if run setuid root. [Andrew
14353 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
14356 *) Fix relative URLs in imagemap files [Randy Terbush]
14358 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
14361 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
14362 entries all name the same one. [David Robinson]
14364 *) Fix directory listings with filenames containing unusual characters
14367 *) Better URI-escaping for generated URIs in directories with filenames
14368 containing unusual characters [Ben Laurie]
14370 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
14372 *) Unblock alarms on error return from spawn_child() [David Robinson]
14374 *) Sample Config files have extra note for SCO users [Ben Laurie]
14376 *) Configuration has note for HP-UX users [Rob Hartill]
14378 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
14380 *) Nuked bogus #define in httpd.h [David Robinson]
14382 *) Better test for whether a system has setrlimit() [David Robinson]
14384 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
14386 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
14389 Changes with Apache 0.8.14 19 Sep 1995
14391 *) Compiles on SCO ODT 3.0 [Ben Laurie]
14393 *) AddDescription works (better) [Ben Laurie]
14395 *) Leaves an intelligible error diagnostic when it can't set group
14396 privileges on standalone startup [Andrew Wilson]
14398 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
14399 that machine, which claims to be BSD but does not support RLIMIT.
14402 *) gcc -Wall no longer complains about an unused variable when util.c
14403 is compiled with -DMINIMAL_DNS [Andrew Wilson]
14405 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
14407 Changes with Apache 0.8.13 07 Sep 1995
14409 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
14411 *) Have built-in imagemap code recognize & honor Point directive [James
14414 *) Generate cleaner directory listings in directories with a mix of
14415 long and short filenames [Rob Hartill]
14417 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
14419 *) Properly default ServerName for virtual servers [Robert Thau]
14421 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
14422 Paul Richards and a cast of thousands...]
14424 *) On self-identified BSD systems (we don't try to guess any more),
14425 allocate a few extra file descriptors per virtual host with setrlimit,
14426 if we can, to avoid running out. [Randy Terbush]
14428 *) Write 22-character lock file name into buffer with enough space
14429 on startup [Konstantin Olchanski]
14431 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
14434 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
14436 *) Suppress -Wall warning by initializing variable in negotiation code
14437 [Tobias Weingartner]
14439 Changes with Apache 0.8.12 31 Aug 1995
14441 *) Doesn't pause three seconds after including a CGI script which is
14442 too slow to die off (this is done by not even trying to kill off
14443 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
14444 after the entire document has been processed). [Robert Thau]
14446 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
14448 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
14450 *) Allows .htaccess files to override <Directory> sections naming the
14451 same directory [David Robinson]
14453 *) Removed an efficiency hack in sub_req_lookup_uri which was
14454 causing certain extremely marginal cases (e.g., ScriptAlias of a
14455 *particular* index.html file) to fail. [David Robinson]
14457 *) Doesn't log an error when the requested URI requires
14458 authentication, but no auth header line was supplied by the
14459 client; this is a normal condition (the client doesn't no auth is
14460 needed here yet). [Robert Thau]
14462 *) Behaves more sanely when the name server loses its mind [Sean Welch]
14464 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
14466 *) RFC931 code no longer passes out name of prior clients on current
14467 requests if the current request came from a server that doesn't
14468 do RFC931. [David Robinson]
14470 *) Configuration script accepts "Module" lines with trailing whitespace.
14473 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
14475 *) Cleaned up comments in mod_cgi.c [Robert Thau]
14477 Changes with Apache 0.8.11 24 Aug 1995
14479 *) Wildcard <Directory> specifications work. [Robert Thau]
14481 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
14483 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
14484 the file being requested itself, in addition to the directories leading
14485 up to it. [Robert Thau]
14487 *) Logs access failures due to symlink checks or invalid client address
14488 in the error log [Roy Fielding, Robert Thau]
14490 *) Symlink checks deal correctly with systems where lstat of
14491 "/path/to/some/link/" follows the link. [Thau, Fielding]
14493 *) Doesn't reset DirectoryIndex to 'index.html' when
14494 other directory options are set in a .htaccess file. [Robert Thau]
14496 *) Clarified init code and nuked bogus warning in mod_access.c
14497 [Florent Guillaume]
14499 *) Corrected several directives in sample srm.conf
14500 --- includes corrections to directory indexing icon-related directives
14501 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
14502 icons for encodings right, and turning on AddEncoding by default).
14505 *) Corrected descriptions of args to AddIcon and AddAlt in command table
14508 *) INSTALL & README mention "contributed modules" directory [Brian
14511 *) Fixed English in the license language... "for for" --> "for".
14514 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
14515 mod_alias.c, merging it almost completely with handling of Alias, and
14516 adding a 'notes' field to the request_rec which allows the CGI module
14517 to discover whether the Alias module has put this request through
14518 ScriptAlias (which it needs to know for back-compatibility, as the old
14519 NCSA code did not check Options ExecCGI in ScriptAlias directories).
14522 Changes with Apache 0.8.10 18 Aug 1995
14524 *) AllowOverride applies to the named directory, and not just
14525 subdirectories. [David Robinson]
14527 *) Do locking for accept() exclusion (on systems that need it)
14528 using a special file created for the purpose in /usr/tmp, and
14529 not the error log; using the error log causes real problems
14530 if it's NFS-mounted; this is known to be the cause of a whole
14531 lot of "server hang" problems with Solaris. [David Robinson;
14532 thanks to Merten Schumann for help diagnosing the problem].
14534 Changes with Apache 0.8.9 12 Aug 1995
14536 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
14538 *) Nested includes see environment variables of the including document,
14539 for NCSA bug-compatibility (some sites have standard footer includes
14540 which try to print out the last-modified date). [Eric Hagberg/Robert
14543 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
14544 URI as a CGI script, even if it would have been treated as something
14545 else if requested directly, for NCSA back-compatibility. (Note that
14546 this means that people who know the name of the script can see the
14547 code just by asking for it). [Robert Thau]
14549 *) New version of dbmmanage script included in support directory as
14552 *) Check if scoreboard file couldn't be opened, and say so, rather
14553 then going insane [David Robinson]
14555 *) POST to CGI works on A/UX [Jim Jagielski]
14557 *) AddIcon and AddAlt commands work properly [Rob Hartill]
14559 *) NCSA server push works properly --- the Arena bug compatibility
14560 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
14561 if you still want the workaround). [Rob Hartill]
14563 *) If client didn't submit any Accept-encodings, ignore encodings in
14564 content negotiation. (NB this will all have to be reworked anyway
14565 for the new HTTP draft). [Florent Guillaume]
14567 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
14569 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
14571 *) Give Redirect priority over Alias, for NCSA bug compatibility
14574 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
14575 paralleling earlier bug fix for CGI [David Robinson]
14577 *) If DBM auth is improperly configured, report a server error and don't
14580 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
14581 it seems to work well enough without it (even in a 10 hits/sec
14582 workout), and the overhead for the locking under A/UX is
14583 alarmingly high (though it is very low on other systems).
14584 [Eric Hagberg, Jim Jagielski]
14586 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
14588 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
14589 Behlendorf/Eric Hagberg]
14591 *) More improvements to default Configuration for A/UX [Jim Jagielski]
14593 *) Compiles clean on NEXT [Rob Hartill]
14595 *) Compiles clean on SGI [Robert Thau]
14597 Changes with Apache 0.8.8 08 Aug 1995
14599 *) SunOS library prototypes now never included unless explicitly
14600 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
14601 people using GNU libc on SunOS are screwed by prototypes for the
14604 (Those who wish to compile clean with gcc -Wall on a standard
14605 SunOS setup need the prototypes, and may obtain them using
14606 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
14607 with nonstandard libraries are presumably competent to make their
14610 *) Strips trailing '/' characters off both args to the Alias command,
14611 to make 'Alias /foo/ /bar/' work.
14613 Changes with Apache 0.8.7 03 Aug 1995
14615 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
14616 [reported by David Robinson]
14618 *) Compiles clean on OSF/1 [David Robinson]
14620 *) Added some of the more recent significant changes (AddLanguage stuff,
14621 experimental LogFormat support) to CHANGES file in distribution root
14624 Changes with Apache 0.8.6 02 Aug 1995
14626 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
14627 (If you actually wanted a conditional GET which bypassed the cache, you
14628 couldn't get it). [Reported by Roy Fielding]
14630 *) Properly terminate headers on '304 Not Modified' replies to conditional
14631 GETs --- no browser we can find cares much, but the CERN proxy chokes.
14632 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
14634 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
14636 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
14637 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
14638 and older versions don't set the __SUNPRO_C preprocessor variable). On
14639 all other systems, these are never used anyway. [Reported by Mark Cox].
14641 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
14643 Changes with Apache 0.8.5 01 Aug 1995
14645 *) Added last-minute configurable log experiment, as optional module
14647 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
14648 properly. (One-line fix to http_protocol.c).
14650 *) Work around bogus behavior when reloading from Netscape.
14651 It's Netscape's bug --- for some reason they expect a request with
14652 If-modified-since: to not function as a conditional GET if it also
14653 comes with Pragma: no-cache, which is way out of line with the HTTP
14654 spec (according to Roy Fielding, the redactor).
14656 *) Added parameter to set maximum number of server processes.
14658 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
14661 *) IdentityCheck bugfix [Chuck Murcko].
14663 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
14665 *) More sample config file corrections; add extension to AddType for
14666 *.asis, move AddType generic description to its proper place, and
14667 fix miscellaneous typos. [ Alexei Kosut ]
14669 *) Deleted the *other* reference to the regents from the Berkeley
14670 legal disclaimer (everyplace).
14672 *) Nuked Shambhala name from src/README; had already cleaned it out
14673 of everywhere else.
14675 Changes with Apache 0.8.4
14677 *) Changes to server-pool management parms --- renamed current
14678 StartServers to MinSpareServers, created separate StartServers
14679 parameter which means what it says, and renamed MaxServers to
14680 MaxSpareServers (though the old name still works, for NCSA 1.4
14681 back-compatibility). The old names were generally regarded as
14682 too confusing. Also altered "docs" in sample config files.
14684 *) More improvements to default config files ---
14685 sample directives (commented out) for XBitHack, BindAddress,
14686 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
14687 defaults, AddTypes for send-as-is and imagemap magic types, and
14688 improvements to samples for DirectoryIndex [Alexei Kosut]
14690 *) Yet more improvements to default config files --- changes to
14691 Alexei's sample AddLanguage directives, and sample LanguagePriority
14692 [ Florent Guillaume ]
14694 *) Set config file locations properly if not set in httpd.conf
14697 *) Don't escape URIs in internal redirects multiple times; don't
14698 do that when translating PATH_INFO to PATH_TRANSLATED either.
14701 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
14703 Changes with Apache 0.8.3
14705 *) Edited distribution README to *briefly* summarize installation
14706 procedures, and give a pointer to the INSTALL file in the src/
14709 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
14710 recent NCSA distributions.
14712 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
14713 exist for the same directory, use both and don't segfault. [Reported
14716 *) Proper makefile dependencies [David Robinson]
14718 *) Note (re)starts in error log --- reported by Rob Hartill.
14720 *) Only call no2slash() after get_path_info() has been done, to
14721 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
14722 reported by Andrew Wilson, though this one is probably a real bug]
14724 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
14725 dump core when Referer is not supplied. [Randy Terbush]
14727 *) Lightly edited sample config files to refer people to our documentation
14728 instead of NCSA's, and to list Rob McCool as *original* author (also
14729 deleted his old, and no doubt non-functional email address). Would be
14730 nice to have examples of new features...
14732 Changes with Apache 0.8.2 19 Jul 1995
14734 *) Added AddLanuage code [Florent Guillaume]
14736 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
14738 *) All sorts of problems when MultiViews finds a directory. It would
14739 be nice if mod_dir.c was robust enough to handle that, but for now,
14740 just punt. [reported by Brian Behlendorf]
14742 *) Wait for all children on restart, to make sure that the old socket
14743 is gone and we can reopen it. [reported by Randy Terbush]
14745 *) Imagemap module is enabled in default Configuration
14747 *) RefererLog and UserAgentLog modules properly default the logfile
14750 *) Mark Cox's mod_cookies added to the distribution as an optional
14751 module (commented out in the default Configuration, and noted as
14752 an experiment, along with mod_dld). [Mark Cox]
14754 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
14756 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
14758 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
14760 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
14763 Changes with Apache 0.8.1
14765 *) New imagemap module [Randy Terbush]
14767 *) Replacement referer log module with NCSA-compatible RefererIgnore
14768 [Matthew Gray again]
14770 *) Don't mung directory listings with very long filenames.
14771 [Florent Guillaume]
14773 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
14775 *) New config script. See INSTALL for info. [Robert Thau]
14777 *) Scoreboard mechanism for regulating the number of extant server
14778 processes. MaxServers and StartServers defaults are the same as
14779 for NCSA, but the meanings are slightly different. (Actually,
14780 I should probably lower the MaxServers default to 10).
14782 Before asking for a new connection, each server process checks
14783 the number of other servers which are also waiting for a
14784 connection. If there are more than MaxServers, it quietly dies
14785 off. Conversely, every second, the root, or caretaker, process
14786 looks to see how many servers are waiting for a new connection;
14787 if there are fewer than StartServers, it starts a new one. This
14788 does not depend on the number of server processes already extant.
14789 The accounting is arranged through a "scoreboard" file, named
14790 /tmp/htstatus.*, on which each process has an independent file
14791 descriptor (they need to seek without interference).
14793 The end effect is that MaxServers is the maximum number of
14794 servers on an *inactive* server machine, but more will be forked
14795 off to handle unusually heavy loads (or unusually slow clients);
14796 these will die off when they are no longer needed --- without
14797 reverting to the overhead of full forking operation. There is a
14798 hard maximum of 150 server processes compiled in, largely to
14799 avoid forking out of control and dragging the machine down.
14800 (This is arguably too high).
14802 In my server endurance tests, this mechanism did not appear to
14803 impose any significant overhead, even after I forced it to put the
14804 scoreboard file on a normal filesystem (which might have more
14805 overhead than tmpfs). [Robert Thau]
14807 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
14810 *) Read .htaccess files even in directory with <Directory> section.
14811 (Former incompatibility noted on mailing list, now fixed). [Robert
14814 *) "HEAD /" gives the client a "Bad Request" error message, rather
14815 than trying to send no body *and* no headers. [Cliff Skolnick].
14817 *) Don't produce double error reports for some very obscure cases
14818 mainly involving auth configuration (the "all modules decline to
14819 handle" case which is a sure sign of a server bug in most cases,
14820 but also happens when authentication is badly misconfigured).
14823 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
14824 it's *for*, and this sort of thing really shouldn't be cluttering
14825 up the Makefile). [Robert Thau]
14827 *) Incidental code cleanups in http_main.c --- stop dragging
14828 sa_client around; just declare it where used. [Robert Thau]
14830 *) Another acc-related fix. (It doesn't like const char
14831 in some places...). [Mark Cox]
14833 Changes with Shambhala 0.6.1 13 Jul 1995
14835 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
14836 Also, fixed auth typo in http_protocol.c unmasked by this fix.
14838 *) Compiles clean with acc on SunOS [Paul Sutton]
14840 *) Reordered modules in modules.c so that Redirect takes priority
14841 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
14842 believe it or not, he has an actual site with a ScriptAlias and
14843 a Redirect declared for the *exact same directory*. Even *my*
14844 compatibility fetish wouldn't motivate me to fix this if the fix
14845 required any effort, but it doesn't, so what the hey.
14847 *) Fixed to properly default several server_rec fields for virtual
14848 servers from the corresponding fields in the main server_rec.
14849 [Cliff Skolnick --- 'port' was a particular irritant].
14851 *) No longer kills off nph- child processes before they are
14852 finished sending output. [Matthew Gray]
14854 Changes with Shambhala 0.6.0 10 Jul 1995
14856 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
14857 the connection to the client in an "aborted" state, but otherwise
14858 allow whatever handlers are running to clean up. hard_timeout()s
14859 abort the request in progress completely; anything not tied to some
14860 resource pool cleanup will leak. They're still around because I
14861 haven't yet come up with a more elegant way of handling
14862 timeouts when talking to something that isn't the client. The
14863 default_handler and the dir_handler now use soft timeouts, largely
14864 so I can test the feature. [Robert Thau]
14866 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
14867 the case of log handlers dying prematurely is probably handled VERY
14868 gracelessly at this point, and if the logger stops reading input,
14869 the server will hang. (It is known to correctly restart the
14870 logging process on server restart; this is (should be!) going through
14871 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
14872 script). [Robert Thau]
14874 *) asis files supported (new module). [Robert Thau]
14876 *) IdentityCheck code is compiled in, but has not been tested. (I
14877 don't know anyone who runs identd). [Robert Thau]
14879 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
14880 came in with the request, for NCSA bug-compatibility. [Robert Thau]
14882 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
14884 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
14885 as timeouts are not in scope. [Robert Thau]
14887 *) quoted-string args in config files now handled correctly (doesn't drop
14888 the last character). [Robert Thau; reported by Randy Terbush]
14890 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
14891 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
14893 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
14894 default default type); the former default default behavior when all
14895 type-checkers defaulted had been a core dump. [Paul Sutton]
14897 *) Copy filenames out of the struct dirent when indexing
14898 directories. (On Linux, readdir() returns a pointer to the same
14899 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
14901 Changes with Shambhala 0.5.3 [not released]
14903 *) Default response handler notes "file not found" in the error log,
14904 if the file was not found. [Cliff Skolnick].
14906 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
14907 code no longer sets up bogus PATH_INFO which fakes out the directory
14908 handler). [Cliff Skolnick]
14910 Changes with Shambhala 0.5.2 06 Jul 1995
14912 *) Changes to http_main.c --- root server no longer plays silly
14913 games with SIGCHLD, and so now detects and replaces dying
14914 children. Child processes just die on SIGTERM, without taking
14915 the whole process group with them. Potential problem --- if any
14916 child process refuses to die, we hang in restart.
14917 MaxRequestsPerChild may still not work, but it certainly works
14918 better than it did before this! [Robert Thau]
14920 *) mod_dir.c bug fixes: ReadmeName and HeaderName
14921 work (or work better, at least); over-long description lines
14922 properly terminated. [Mark Cox]
14924 *) http_request.c now calls unescape_url() more places where it
14925 should [Paul Sutton].
14927 *) More directory handling bugs (reported by Cox)
14928 Parent Directory link is now set correctly. [Robert Thau]
14930 Changes with Shambhala 0.5.1 04 Jul 1995
14932 *) Generalized cleanup interface in alloc.c --- any function can be
14933 registered with alloc.c as a cleanup for a resource pool;
14934 tracking of files and file descriptors has been reimplemented in
14935 terms of this interface, so I can give it some sort of a test.
14938 *) More changes in alloc.c --- new cleanup_for_exec() function,
14939 which tracks down and closes all file descriptors which have been
14940 registered with the alloc.c machinery before the server exec()s a
14941 child process for CGI or <!--#exec-->. CGI children now get
14942 started with exactly three file descriptors open. Hopefully,
14943 this cures the problem Rob H. was having with overly persistent
14944 CGI connections. [Robert Thau]
14946 *) Mutual exclusion around the accept() in child_main() --- this is
14947 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
14948 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
14949 This uses fcntl(F_SETLK,...) on the error log descriptor because
14950 flock() on that descriptor won't work on systems which have BSD
14951 flock() semantics, including (I think) Linux 1.3 and Solaris.
14953 This does work on SunOS (when the server is idle, only one
14954 process in the pool is waiting on accept()); it *ought* to work
14955 on the other systems. [Robert Thau]
14957 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
14959 *) sizeof(*sa_client) bugfix from [Rob Hartill]
14961 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
14963 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
14964 be unnecessary if I go to the revised timeout-handling scheme).
14967 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
14968 string) even if none came in with the request. [Robert Thau]
14970 *) CHANGES file added to distribution ;-).
14972 Changes with Shambhala 0.4.5
14974 *) mod_dld --- early dynamic loading support [rst]
14975 *) Add wildcard content handlers for XBITHACK; default_hander now
14976 invoked with that mechanism (as a handler hanging off mod_core) [rst]
14977 *) XBITHACK supported as a wildcard content-handler, and
14978 configurable at run-time (not just at compile time, as in the
14979 "patchy server" releases) [rst]
14981 Changes with Shambhala 0.4.4 30 Jun 1995
14983 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
14984 *) Handle Addtype x/y .z [rst, reported by Cox]
14986 Changes with Shambhala 0.4.3
14988 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
14989 synonymous [rst, terbush]
14991 Changes with Shambhala 0.4.1 28 Jun 1995
14993 *) First-cut virtual host implementation; some refit in the config
14994 reading code, and log management, was necessary to support this [rst]
14995 *) Sub-pool machinery, originally added to avoid excessive storage
14996 allocation on listings of large directories (which turned out to
14997 be the problem that the 0.3 storage accounting was added to
14998 find). Subrequests and mod_dir changed to use subpools. [rst]
14999 *) More memory debugging --- free list consistency checks. [rst]
15000 *) Added err_headers to request_rec, with support elsewhere [rst]
15001 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
15003 Changes with Shambhala 0.3 19 Jun 1995
15005 *) Switch ONE_PROCESS to a runtime command-line option (-X)
15006 *) Don't compile in mod_ai_backcompat by default
15007 *) Switch name of server from Apache to Shambhala in Makefile
15008 *) Add some accounting routines to track memory usage in the pools,
15011 Changes with Shambhala 0.2
15013 *) Set DOCUMENT_ROOT CGI variable
15014 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
15015 *) Add critical section protection to handling of cleanup structures
15017 *) Significant code reorg within the server core to group related
15018 functions together [rst]
15019 *) Correctly handle clients that hang up before sending any request
15021 *) Replace dying child processes. [rst]
15023 Changes with Shambhala 0.1 12 Jun 1995
15025 Major rewrite of the pre-existing "patchy server" codebase, by
15026 Robert Thau (rst). Significant portions of the server code, such
15027 as configuration-file handling and HTTP authentication support,
15028 were ripped out and rewritten from scratch. Code that was not
15029 completely rewritten was significantly altered.
15031 Major changes with this release include:
15033 *) Introduction of the module API; in request handling, the central
15034 machinery just dispatches to various modules, which actually do
15035 most of the work. Configuration handling is similar --- modules
15036 declare their own commands, and the central machinery just
15037 dispatches to them.
15039 API features from shambhala/0.1 were substantially unchanged in
15040 Apache 1.0 and 1.1. (1.0 API features not yet present in this
15041 release, such as wildcard handlers and subpools, were added in
15042 subsequent Shambhala releases, and were also generally rst's
15045 *) This release included the following modules:
15047 mod_access (access control --- allow and deny directives),
15048 mod_alias (Alias and Redirect commands),
15049 mod_auth (straight HTTP authentication, based on flat-files)
15050 mod_auth_dbm (same, with dbm files)
15051 mod_cgi (CGI scripts and, in this release, ScriptAlias)
15052 mod_common_log (CLF access logs; later renamed mod_log_common)
15053 mod_dir (directory indexing)
15054 mod_include (server-side includes)
15055 mod_mime (AddType directives)
15056 mod_negotiation (content negotiation)
15057 mod_userdir (support for users' public_html directories)
15059 It also included a mod_ai_backcompat, which was a private hack
15060 for back-compatibility with rst's own AI-lab servers.
15062 All of these modules were substantially complete, and functional
15063 or nearly so (a few, which implemented features not in use at
15064 Thau's site, required patches of a few lines).
15066 *) sub-request machinery, to allow modules to determine how other
15067 modules would assign MIME types to a given file, or optionally
15068 serve its content (this is heavily used by mod_dir, mod_include
15069 and mod_negotiation).
15071 *) Resource pool system for keeping track of memory allocated and
15072 files opened in service of a particular request. Much of the
15073 code in the modules (when they weren't rewrites) was adjusted to
15074 replace a pervasive convention of using fixed-size buffers on
15075 the stack with an equally pervasive convention of using memory
15076 allocated with palloc().
15078 *) Reorganization of data structures associated with a given
15079 request to eliminate use of global variables and the troublesome
15080 unmunge_name function (used in NCSA and early Apache releases to
15081 attempt to determine the URI which mapped to a given filename
15082 --- a difficult proposition, given that it is easy to produce
15083 setups in which multiple URIs map to the same file).
15085 *) Source files renamed and rearranged
15087 *) Very simple pre-forking behavior --- parent process forked off a
15088 fixed number of children, and then just waited for SIGHUP.
15090 *) Other more minor changes too numerous to list.
15092 This release included modified versions of a lot of code from the
15093 Apache 0.6.4 public release, plus an early pre-forking patch
15094 codeveloped by Robert Thau and Rob Hartill.
15096 Changes with Apache 0.7.3 20 Jun 1995
15098 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
15099 were incorporated by Rob Hartill on the main branch while Robert Thau
15100 worked on the Shambhala rewrite above. Most were merged into the
15101 Shambala architecture after Apache 0.8.0.
15103 Changes with Apache 0.6.4 13 May 1995
