3 [Remove entries to the current 2.0 section below, when backported]
5 *) Quotes cannot be used around require group and require dn
6 directives, update the documentation to reflect this. Also add
7 quotes around the dn and group within debug messages, to make it
8 more obvious why authentication is failing if quotes are used in
9 error. PR 19304 [Graham Leggett]
11 *) The Microsoft LDAP SDK escapes filters for us, stop util_ldap
12 from escaping filters twice when the backslash character is used.
13 PR 24437 [Jess Holle <jessh@ptc.com>]
15 *) Overhaul handling of LDAP error conditions, so that the util_ldap_*
16 functions leave the connections in a sane state after errors have
17 occurred. PR 27748, 17274, 17599, 18661, 21787, 24595, 24683, 27134,

58 PR 28492. [André Malo]
60 *) Recursive Include directives no longer crash. The server stops
61 including configuration files after a certain nesting level (128

85 argument is not recognized as an URL, assume it's a mail address.
86 PR 28174. [André Malo]
88 *) mod_rewrite no longer confuses the RewriteMap caches if
89 different maps defined in different virtual hosts use the

137 *) Threaded MPMs for Unix and Win32: Add support for ThreadStackSize
138 directive (previously NetWare-only) to override default thread
139 stack size for threads which handle client connections. Required
140 for some third-party modules on platforms with small default
141 thread stack size. [Jeff Trawick]

147 never worked at all. PR 25725. [André Malo]
149 *) minor mod_auth_basic and mod_auth_digest sync. mod_auth_basic
150 now populates r->user with the (possibly unauthenticated) user,
151 and mod_auth_digest returns 500 when a provider returns
155 *) mod_isapi: send_response_header() failed to copy status string's
156 last character. PR 20619. [Jesse Pelton <jsp pkc.com>]
158 *) The whole codebase was relicensed and is now available under
159 the Apache License, Version 2.0 (http://www.apache.org/licenses).

177 rewritemap programs no longer need to switch stdout to binary
178 mode. PR 25635. [André Malo]
180 *) mod_rewrite: Introduce the ability to force a content handler via

239 *) Switch to APR 1.0 API.
241 *) Major overhaul of mod_include's filter parser. The new parser code
242 is expected to be more robust and should catch all of the edge cases
243 that were not handled by the previous one. This includes a binary
244 incompatible change of mod_include's external API. [André Malo]
246 *) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
247 PR 14223. [André Malo]
249 *) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously

270 hopefully saves some hours of searching for typos. PR 12863.
273 *) mod_actions: Propagate the handler name to the action script via
274 the REDIRECT_HANDLER environment variable. [André Malo]
276 *) mod_actions: Introduce the "virtual" modifier to the Action directive,
277 which allows the use of handlers for virtual locations. PR 8431.

311 PR 17564. [André Malo]
313 *) Extend mod_negotiation to evaluate the environment variables
314 no-gzip and gzip-only-text/html the same way as mod_deflate does.
317 *) mod_rewrite: Fix some problems reporting errors with mapping
318 programs (RewriteMap prg:/something). [Jeff Trawick]
320 *) Return 413 if chunk-ext-header is too long rather than reading from
321 the truncated line. PR 15857. [Justin Erenkrantz]
323 *) Allow restart of httpd to occur even with syntax errors in the config
324 file. PR 16813. [Justin Erenkrantz]

341 *) Forward port of mod_actions' ability to handle arbitrary methods
342 with the Script directive. [André Malo]
344 *) Let suexec send a message to stderr, if it failed or its policy
345 was violated. This message appears in the error log and allows
346 for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
348 *) Modify buildconf to copy all required files into httpd's tree.

351 *) Allow mod_dav to do weak entity comparison functions.
354 *) Move RFC 1413 ident requests from core to new module mod_ident.
357 *) Add mod_authz_owner - a forward port of "Require file-owner"
358 and "Require file-group", which was already present in version
361 *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
364 *) Replace some of the mutex locking in the worker MPM with
365 atomic operations for higher concurrency. [Brian Pane]
367 *) Allow 'make depend' to work with non-GCC compilers.
370 *) If an httpd.conf has commented out AddModule directives,
371 apxs -i -a will add an un-commented AddModule directive for
372 the new module, which breaks the config.
373 PR: 11212 [Joe Orton]
375 *) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
377 *) Move the check of the Expect request header field after the hook

440 bucket brigades containing multiple file buckets all referencing
441 the same open file descriptor. [Bojan Smojver]
443 *) Fix memory corruption problem with ap_custom_response() function.
444 The core per-dir config would later point to request pool data
445 that would be reused for different purposes on different requests.

448 *) Win32: Tweak worker thread accounting routines to eliminate
449 server hang when number of Listen directives in httpd.conf
450 is greater than or equal to the setting of ThreadsPerChild.
453 Changes with Apache 2.0.49
455 *) SECURITY: CAN-2004-0174 (cve.mitre.org)
456 Fix starvation issue on listening sockets where a short-lived
457 connection on a rarely-accessed listening socket will cause a
458 child to hold the accept mutex and block out new connections until
459 another connection arrives on that rarely-accessed listening socket.
460 With Apache 2.x there is no performance concern about enabling the
461 logic for platforms which don't need it, so it is enabled everywhere
462 except for Win32. [Jeff Trawick]
464 *) mod_cgid: Fix storage corruption caused by use of incorrect pool.
467 *) Win32: find_read_listeners was not correctly handling multiple
468 listeners on the Win32DisableAcceptEx path. [Bill Stoddard]
470 *) Fix bug in mod_usertrack when no CookieName is set. PR 24483.
471 [Manni Wood <manniwood planet-save.com>]

548 *) core.c: If large file support is enabled, allow any file that is
549 greater than AP_MAX_SENDFILE to be split into multiple buckets.
550 This allows Apache to send files that are greater than 2gig.
551 Otherwise we run into 32/64 bit type mismatches in the file size.
554 *) proxy_http fix: mod_proxy hangs when both KeepAlive and
555 ProxyErrorOverride are enabled, and a non-200 response without a
556 body is generated by the backend server. (e.g.: a client makes a
557 request containing the "If-Modified-Since" and "If-None-Match"
558 headers, to which the backend server respond with status 304.)
559 [Graham Wiseman <gwiseman fscinternet.com>, Richard Reiner]

579 *) worker MPM: fix stack overlay bug that could cause the parent
580 process to crash. [Jeff Trawick]
582 *) Win32: Add Win32DisableAcceptEx directive. This Windows
583 NT/2000/CP directive is useful to work around bugs in some
584 third party layered service providers like virus scanners,
585 VPN and firewall products, that do not properly handle
586 WinSock 2 APIs. Use this directive if your server is issuing
587 AcceptEx failed messages.

1163 *) Updated mod_ldap and mod_auth_ldap to support the Novell LDAP SDK SSL
1164 and standardized the LDAP SSL support across the various LDAP SDKs.
1165 Isolated the SSL functionality to mod_ldap rather than speading it
1166 across mod_auth_ldap and mod_ldap. Also added LDAPTrustedCA
1167 and LDAPTrustedCAType directives to mod_ldap to allow for a more
1168 common method of specifying the SSL certificate.

1694 log file [Ian Holsman]
1696 *) Correct ISAPIReadAheadBuffer to default to 49152, per mod_isapi docs.

1705 *) New option to ServerTokens 'maj[or]'. Only show the major version
1706 Also Surfaced this directive in the standard config (default FULL)
1709 *) Change mod_rewrite to use apr-util's dbm support for dbm rewrite
1710 maps. The dbm type (e.g., ndbm, gdbm) can be specified on the
1711 RewriteMap directive. PR 10644 [Jeff Trawick]
1713 *) Fixed mod_rewrite's RewriteMap prg: support so that request/response
1714 pairs will no longer get out of sync with each other. PR 9534

1728 [Ian Darwin <Ian779 darwinsys.com>]
1730 *) thread safety & proxy-ftp [Alexey Panchenko <alexey liwest.ru>, Ian Holsman]
1732 *) mod_disk_cache works much better. This module should still
1733 be considered experimental. [Eric Prud'hommeaux]
1735 *) Performance improvement for keepalive requests: when setting
1736 aside a small file for potential concatenation with the next
1737 response on the connection, set aside the file descriptor rather
1738 than copying the file into the heap. [Brian Pane]
1740 *) Modified version check on openssl so that it finds the executable
1741 first and then performs a check of the version, only warning the
1742 user if they chose, or we selected, an old version of OpenSSL.
1743 This change also allows the code to work for non-openssl libraries
1744 selected via the --with-ssl=dir option, which can override the
1745 automated library check in any case. [Roy Fielding]
1747 Changes with Apache 2.0.40
1749 *) SECURITY [CAN-2002-0661] (cve.mitre.org):
1750 Close a very significant security hole that
1751 applies only to the Win32, OS2 and Netware platforms. Unix was not
1752 affected, Cygwin may be affected. Certain URIs will bypass security
1753 and allow users to invoke or access any file depending on the system
1754 configuration. Without upgrading, a single .conf change will close
1755 the vulnerability. Add the following directive in the global server
1756 httpd.conf context before any other Alias or Redirect directives;
1757 RedirectMatch 400 "\\\.\."
1758 Reported by Auriemma Luigi <bugtest sitoverde.com>.
1761 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1762 Close a path-revealing exposure in multiview type
1763 map negotiation (such as the default error documents) where the
1764 module would report the full path of the typemapped .var file when
1765 multiple documents or no documents could be served based on the mime
1766 negotiation. Reported by Auriemma Luigi <bugtest sitoverde.com>.
1769 *) SECURITY [CAN-2002-0654] (cve.mitre.org):
1770 Close a path-revealing exposure in cgi/cgid when we
1771 fail to invoke a script. The modules would report "couldn't create
1772 child process /path-to-script/script.pl" revealing the full path
1773 of the script. Reported by Jim Race <jrace qualys.com>.
1776 *) Set aside the apr-iconv and apr_xlate() features for the Win32
1777 build of 2.0.40 so development can be completed. A patch, from
1778 <http://www.apache.org/dist/httpd/patches/apply_to_2.0.40/>
1779 will be available for those that wish to work with apr-iconv.
1782 *) Fix proxy so that it is possible to access ftp: URLs via a proxy
1783 chain. [Peter Van Biesen <peter.vanbiesen vlafo.be>]
1785 *) mod-deflate now checks to make sure that 'gzip-only-text/html' is
1786 set to 1, so we can exclude things from the general case with
1787 browsermatch. [Ian Holsman, Andre Schild <A.Schild aarboard.ch>]
1789 *) Accept multiple leading /'s for requests within the DocumentRoot.
1790 PR 10946 [William Rowe, David Shane Holden <dpejesh yahoo.com>]
1792 *) Solved the reports of .pdf byterange failures on Win32 alone.
1793 APR's sendfile for the win32 platform collapses header and trailer
1794 buffers into a single buffer. However, we destroyed the pointers
1795 to the header buffer if a trailer buffer was present. PR 10781
1798 *) mod_ext_filter: Add the ability to enable or disable a filter via
1799 an environment variable. Add the ability to register a filter of
1800 type other than AP_FTYPE_RESOURCE. [Jeff Trawick]
1802 *) Restore the ability to specify host names on Listen directives.
1803 PR 11030. [Jeff Trawick, David Shane Holden <dpejesh yahoo.com>]
1805 *) When deciding on the default address family for listening sockets,
1806 make sure we can actually bind to an AF_INET6 socket before
1807 deciding that we should default to AF_INET6. This fixes a startup
1808 problem on certain levels of OpenUNIX. PR 10235. [Jeff Trawick]
1810 *) Replace usage of atol() to parse strings when we might want a
1811 larger-than-long value with apr_atoll(), which returns long long.
1812 This allows HTTPD to deal with larger files correctly.
1813 [Shantonu Sen <ssen apple.com>]
1815 *) mod_ext_filter: Ignore any content-type parameters when checking if
1816 the response should be filtered. Previously, "intype=text/html"
1817 wouldn't match something like "text/html;charset=8859_1".
1820 *) mod_ext_filter: Set up environment variables for external programs.
1821 [Craig Sebenik <craig netapp.com>]
1823 *) Modified the HTTP_IN filter to immediately append the EOS (end of
1824 stream) bucket for C-L POST bodies, saving a roundtrip and allowing
1825 the caller to determine that no content remains without prefetching
1826 additional POST body. [William Rowe]
1828 *) Get proxy ftp to work over IPv6. [Shoichi Sakane <sakane kame.net>]
1830 *) Look for OpenSSL libraries in /usr/lib64. [Peter Poeml <poeml suse.de>]
1832 *) Update SuSE layout. [Peter Poeml <poeml suse.de>]
1834 *) Changes to the internationalized error documents:
1835 Comment them out in the default config file to make the default
1836 install as simple as possible; Correct the english 500 error to
1837 be more understandable; Add a Swedish translation.
1838 [Thomas Sjogren <thomas northernsecurity.net>,
1839 Erik Abele <erik codefaktor.de>, Rich Bowen, Joshua Slive]
1841 *) Increase the limit on file descriptors per process in apachectl.
1844 *) Fix a dependency error when building ApacheMonitor, so that Win32
1845 and MSVC now trust that the project is current (when it is).
1846 [James Cox <imajes php.net>]
1848 *) mod_ext_filter: don't segfault if content-type is not set. PR 10617.
1849 [Arthur P. Smith <apsmith aps.org>, Jeff Trawick]
1851 *) APR-Util Renames pending have been completed [Thom May]
1853 *) Performance improvements for the code that reads request
1854 headers (ap_rgetline_core() and related functions) [Brian Pane]
1856 *) Add a new directive: MaxMemFree. MaxMemFree makes it possible
1857 to configure the maximum amount of memory the allocators will
1858 hold on to for reuse. Anything over the MaxMemFree threshold
1859 will be free()d. This directive is useful when uncommon large
1860 peaks occur in memory usage. It should _not_ be used to mask
1861 defective modules' memory use. [Sander Striker]
1863 *) Fixed the Content-Length filter so that HTTP/1.0 requests to CGI
1864 scripts would not result in a truncated response.
1865 [Ryan Bloom, Justin Erenkrantz, Cliff Woolley]
1867 *) Add a filter_init parameter to the filter registration functions
1868 so that a filter can execute arbitrary code before the handlers
1869 are invoked. This resolves a problem where mod_include requests
1870 would incorrectly return a 304. [Justin Erenkrantz]
1872 *) Fix a long-standing bug in 2.0, CGI scripts were being called
1873 with relative paths instead of absolute paths. Apache 1.3 used
1874 absolute paths for everything except for SuExec, this brings back
1875 that standard. [Ryan Bloom]
1877 *) Fix infinite loop due to two HTTP_IN filters being present for
1878 internally redirected requests. PR 10146. [Justin Erenkrantz]
1880 *) Switch conn_rec->keepalive to an enumeration rather than a bitfield.
1883 *) Fix mod_ext_filter to look in the main server for filter definitions
1884 when running in a vhost if the filter definition is not found in
1885 the vhost. PR 10147 [Jeff Trawick]
1887 *) Support WinNT CGI invocation through ScriptInterpreterSource
1888 'registry' for script interpreter paths and names with non-ascii
1889 characters in the executable filepath. [William Rowe]
1891 *) Support the -w flag on to keep the Win32 console open on error.
1894 *) Normalize the hostname value in the request_rec to all-lowercase
1895 [Perry Harrington <pedward webcom.com>]
1897 *) Fix WinNT cgi 500 errors when QUERY_ARGS or other strings include
1898 extended characters (non US-ASCII) in non-utf8 format. This brings
1899 Win32 back into CGI/1.1 compliance, and leaves charset decoding up
1900 to the cgi application itself. [William Rowe]
1902 *) Major overhaul of mod_dav, mod_dav_fs and the experimental/cache
1903 modules to bring them up to the current apr/apr-util APIs.
1906 *) Fix segfault in mod_mem_cache most frequently observed when
1907 serving the same file to multiple clients on an MP machine.
1910 *) mod_rewrite can now set cookies (RewriteRule (.*) - [CO=name:$1:.domain])
1911 [Brian Degenhardt <bmd mp3.com>, Ian Holsman]
1913 *) Fix perchild to work with apachectl by adding -k support to perchild.
1914 PR 10074 [Jeff Trawick]
1916 *) Fix a silly htpasswd.c logic error that incorrectly reported that
1917 both -c and -n had been used. PR 9989 [Cliff Woolley]
1919 *) Fixed a mod_include error case in which no HTTP response was sent
1920 to the client if an shtml document contained an unterminated SSI
1921 directive [Brian Pane]
1923 *) Improve ap_get_client_block implementation by using APR-util brigade
1924 helper functions and relying on current filter assumptions.
1927 Changes with Apache 2.0.39
1929 *) Fixed a build problem in htpasswd.c on Win32.
1930 [Guenter Knauf <eflash gmx.net>, Cliff Woolley]
1932 Changes with Apache 2.0.38
1934 *) Rewrite htpasswd to use APR. The removes the annoying warning about
1935 tmpnam being unsafe. [Ryan Bloom]
1937 *) We must set the MIME-type for .shtml files to text/html if we want them
1938 to be parsed for SSI tags. Add the config for that to the default
1939 config file so that it is easier to enable .shtml parsing.
1940 [Dave Dyer <ddyer real-me.net>]
1942 *) Fixed a problem with 'make install' on ReliantUnix.
1943 [Jean-frederic Clere <jfrederic.clere fujitsu-siemens.com>]
1945 *) Make the default_handler catch all requests that aren't served by
1946 another handler. This also gets us to return a 404 if a directory
1947 is requested, there is no DirectoryIndex, and mod_autoindex isn't
1948 loaded. [Justin Erenkrantz]
1950 *) Fixed the handling of nested if-statements in shtml files.
1951 PR 9866 [Brian Pane]
1953 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
1954 into a directory different from the one that was configured. This
1955 also mirrors the root= feature from 1.3. We cannot use prefix=,
1956 because both APR and APR-util resolve their installation paths at
1957 configuration time. This means that there is no variable prefix
1958 to replace. [Andreas Hasenack <andreas netbank.com.br>]
1960 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1961 These levels of AIX don't have a thundering herd problem with
1962 accept(). [Jeff Trawick]
1964 *) prefork MPM: Ignore mutex errors during graceful restart. For
1965 certain types of mutexes (particularly SysV semaphores), we
1966 should expect to occasionally fail to obtain or release the
1967 mutex during restart processing. [Jeff Trawick]
1969 *) Fix install-bindist.sh so that it finds any perl instead of just
1970 early perl 5.x versions. This is consistent with a build/install
1971 from source, and it allows the perl scripts installed by a bindist
1972 to work on systems with perl 5.6. [Jeff Trawick]
1974 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
1975 Tru64 (and probably some other platforms). [Jeff Trawick]
1977 *) Allow CGI scripts to return their Content-Length. This also fixes a
1978 hang on HEAD requests seen on certain platforms (such as FreeBSD).
1981 *) Added log rotation based on file size to the RotateLog support
1982 utility. [Brad Nicholes]
1984 *) Fix some casting in mod_rewrite which broke random maps.
1985 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
1987 Changes with Apache 2.0.37
1989 *) allow POST method over SSL when per-directory client cert
1990 authentication is used with 'SSLOptions +OptRenegotiate' enabled
1991 and a client cert was found in the ssl session cache.
1993 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
1994 session cache when there is no cert chain in the cache. prior to
1995 the fix this situation would result in a FORBIDDEN response and
1996 error message "Cannot find peer certificate chain"
1999 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
2000 one was already sent. PR 9644 [Jeff Trawick]
2002 *) Fix the display of the default name for the mime types config
2003 file. PR 9729 [Matthew Brecknell <mbrecknell orchestream.com>]
2005 *) Fix the working directory *for WinNT/2K/XP services only* to
2006 change to the Apache directory (one level above the location
2007 of Apache.exe, in the case that Apache.exe resides in bin/.)
2008 Solves the case of ServerRoot /foo paths where /foo was not
2009 on the same drive as /winnt/system32. [William Rowe]
2011 *) Make 2.0's "AcceptMutex" startup message now "completely"
2012 match how 1.3 does it. [Jim Jagielski]
2014 *) Implement a fixed size memory cache using a priority queue
2017 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
2018 querying certain other variables from config_vars.mk. PR 9316
2021 *) Added the "detached" attribute to the cgi_exec_info_t internals
2022 so that Win32 and Netware won't create a new window or console
2023 for each CGI invoked. PR 8387
2024 [Brad Nicholes, William Rowe]
2026 *) Consolidated the command line parameters and attributes that are
2027 manipulated by the optional function ap_cgi_build_command() in
2028 mod_cgi into a single structure.
2031 *) Get rid of uninitialized value errors with "apxs -q" on certain
2032 variables. [Stas Bekman <stas stason.org>]
2034 *) Fix apxs to allow it to work when the build directory is somewhere
2035 besides server-root/build. PR 8453
2036 [Jeff Trawick and a host of others]
2038 *) Allow ap_discard_request_body to be called multiple times in the
2039 same request. Essentially, ap_http_filter keeps track of whether
2040 it has sent an EOS bucket up the stack, if so, it will only ever
2041 send an EOS bucket for this request.
2042 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
2044 *) Remove all special mod_ssl URIs. This also fixes the bug where
2045 redirecting (.*) will allow an SSL protected page to be viewed
2046 without SSL. [Ryan Bloom]
2048 *) Fix the binary build install script so that the build logic
2049 created by "apxs -g" will work when the user has a binary
2050 build. [Jeff Trawick]
2052 *) Allow instdso.sh to work with full paths to the shared module.
2055 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
2056 in module for NetWare [Brad Nicholes]
2058 *) Changed cgi and piped log behavior to accept 65536 characters
2059 on Win32 (matching Linux) before deadlocking between outputing
2060 client stdin, slurping the output from stdout and then the stderr
2061 stream. PR 8179 [William Rowe]
2063 *) Fixed Win32 wintty.exe support to assure the window title is valid.
2064 Elimiates possible gpfault or garbage title without the -t option.
2067 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
2068 brigades and input filters. [Justin Erenkrantz]
2070 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
2071 body. [Justin Erenkrantz]
2073 *) NetWare: Piping log entries through RotateLogs using the
2074 CustomLogs directive is finally supported now that we have
2075 the pipes and spawning functionality working.

2090 *) Fix the TIME_* SSL var lookups to be threadsafe. PR 9469.
2093 *) Ensure that apr_brigade_write() flushes in all of the cases that
2094 it should to avoid conditions in some modules that could cause
2095 large amounts of data to be buffered. [Cliff Woolley]
2097 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
2098 stripping the content_type from cached responses.
2101 *) apachectl passes through any httpd options. Note: apachectl
2102 should be used in preference to httpd since it ensures that any
2103 appropriate environment variables have been set up.
2106 *) Fix the combination of mod_cgid, mod_setuexec, and mod_userdir.

2127 from working on Unix. [Jeff Trawick]
2129 *) Add "-k start|restart|graceful|stop" support to httpd for the Unix

2149 It is currently ignored and it will be removed in a future release
2150 of Apache. [Jeff Trawick]
2152 *) Removed documentation references to the no-longer-supported
2153 "make certificate" feature of mod_ssl for Apache 1.3.x. Test
2154 certificates, if truly desired, can be generated using openssl
2155 commands. PR 8724. [Cliff Woolley]
2157 *) Remove SSLLog and SSLLogLevel directives in favor of having
2158 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
2160 *) OS/390: LIBPATH no longer has to be manually uncommented in
2161 envvars to get apachectl to set up httpd properly. [Jeff Trawick]
2163 *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
2164 may now be specified to the <File/Directory > container, rather

2170 *) mod_isapi: Major refactoring of the code to rely on apr internals
2171 rather than MS APIs (using our own mod_isapi.h headers for ISAPI
2172 symbol definitions.) [William Rowe]
2174 *) mod_isapi: Fixed the return string length from GetServerVariable

2245 This left the user in an ambiguous state. PR 8320 [Paul J. Reder]
2247 *) Close sockets on worker MPM when doing a graceless restart.
2250 *) Reverted a minor optimization in mod_ssl.c that used the vhost ID
2251 as the session id context rather that a MD5 hash of that vhost ID,
2252 because it caused very long vhost id's to be unusable with mod_ssl.

2255 *) Fix the link to the description of the CoredumpDirectory
2256 directive in the server-wide document. PR 8643. [Jeff Trawick]
2258 *) Fixed SHMCB session caching. [Aaron Bannert, Cliff Woolley]
2260 *) Synced with remaining changes from mod_ssl 2.8.8-1.3.24:
2261 - Avoid SIGBUS on sparc machines with SHMCB session caches
2262 - Allow whitespace between the pipe and the name of the
2263 program in SSLLog "| /path/to/program". [Cliff Woolley]
2265 *) Introduce mod_ext_filter and mod_deflate experimental modules
2266 to the Win32 build (zlib sources must be in srclib\zlib.)
2269 *) Changes to the worker MPM's queue management and thread
2270 synchronization code to reduce mutex contention [Brian Pane]
2272 *) Don't install *.in configuration files since we already install
2273 *-std.conf files. [Aaron Bannert]
2275 *) Many improvements to the threadpool MPM. [Aaron Bannert]
2277 *) Fix subreqs that are promoted via fast_redirect from having invalid
2278 frec->r structures. This would cause subtle errors later on in
2279 request processing such as seen in PR 7966. [Justin Erenkrantz]
2281 *) More efficient pool recycling logic for the worker MPM [Brian Pane]
2283 *) Modify the worker MPM to not accept() new connections until
2284 there is an available worker thread. This prevents queued
2285 connections from starving for processing time while long-running
2286 connections were hogging all the available threads. [Aaron Bannert]
2288 *) Convert the worker MPM's fdqueue from a LIFO back into a FIFO.
2291 *) Get basic HTTP proxy working on EBCDIC machines. [Jeff Trawick]
2293 *) Allow mod_unique_id to work on systems with no IPv4 address

2329 ap_uname2id. [Scott Lamb <slamb slamb.org>]
2331 *) Fix AcceptPathInfo. PR 8234 [Cliff Woolley]
2333 *) SECURITY: Added the APLOG_TOCLIENT flag to ap_log_rerror() to
2334 explicitly tell the server that warning messages should be sent
2335 to the client in addition to being recorded in the error log.
2336 Prior to this change, ap_log_rerror() always sent warning
2337 messages to the client. In one case, a faulty CGI script caused
2338 the server to send a warning message to the client that contained
2339 the full path to the CGI script. This could be considered a
2340 minor security exposure. [Bill Stoddard]
2342 *) mod_autoindex output when SuppressRules was specified would
2343 omit the first carriage return so the first item in the list
2344 would appear to the right of the column headings instead of
2345 underneath them. PR 8016 [David Shane Holden <dpejesh yahoo.com>]

2349 at init everytime you use the MMapFile directive. PR 8314
2352 *) Trigger an error when a LoadModule directive attempts to
2353 load a module which is built-in. This is a common error when
2354 switching from a DSO build to a static build. [Jeff Trawick]
2356 *) Change instdso.sh to use libtool --install everywhere and then
2357 clean up some stray files and symlinks that libtool leaves around
2358 on some platforms. This gets subversion building properly since
2359 it needed a re-link to be performed by libtool at install time,
2360 and the old instdso.sh logic to simply cp the DSO didn't handle
2361 that requirement. [Sander Striker]

2372 *) Fix segfault in mod_mem_cache when garabge collecting an expired
2373 cache entry. [Bill Stoddard]
2375 *) Introduced -E startup_logfile_name option to httpd to allow admins
2376 to begin logging errors immediately. This provides Win32 users
2377 an alternative to sending startup errors to the event viewer, and
2378 allows other daemon tool authors an alternative to logging to stderr.

2464 "<!--#" occurs at the very end of a bucket
2465 [Paul Reder, Brian Pane]
2467 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
2468 cause the Apache parent process to run in the foreground (similar to
2469 -DNO_DETACH except that it doesn't switch session ids).
2472 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
2473 for those platforms that support it. If using the default
2474 implementation, this is between pthread and sysvsem in priority.
2475 This implies it's the new default for Darwin. [Jim Jagielski]
2477 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
2478 environment variables in the envvars file. [Jeff Trawick]
2480 *) worker MPM: Don't create a listener thread until we have a worker
2481 thread. Otherwise, in situations where we'll have to wait a while
2482 to take over scoreboard slots from a previous generation, we'll be
2483 accepting connections we can't process yet. [Jeff Trawick]
2485 *) Allow worker MPM to build on systems without pthread_kill().

2488 *) Prevent ap_add_output_filters_by_type from being called in
2489 ap_set_content_type if the content-type hasn't changed.

2511 *) Made AB's use of the Host: header rfc2616 compliant
2512 by Taisuke Yamada <tai iij.ad.jp> [Dirk-Willem van Gulik].
2514 *) The old, legacy (and unused) code in which the scoreboard was totally
2515 and completely contained in a file (SCOREBOARD_FILE) has been
2516 removed. This does not affect scoreboards which are *mapped* to
2517 files using named-shared-memory. [Jim Jagielski]
2519 *) Change bucket brigades API to allow a "bucket allocator" to be
2520 passed in at certain points. This allows us to implement freelists
2521 so that we can stop using malloc/free so frequently.
2522 [Cliff Woolley, Brian Pane]

2554 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
2556 *) When a proxied site was being served, Apache was replacing
2557 the original site Server header with it's own, which is not
2558 allowed by RFC2616. Fixed. [Graham Leggett]
2560 *) Fix a mod_cgid problem that left daemon processes stranded
2561 in some server restart scenarios. [Jeff Trawick]
2563 *) Added exp_foo and rel_foo variables to config_vars.mk for
2564 all Apache and Autoconf path variables (like --sysconfdir,
2565 --sbindir, etc). exp_foo is the "expanded" version, which means
2566 that all internal variable references have been interpolated.
2567 rel_foo is the same as $exp_foo, only relative to $prefix if they
2568 share a common path. [Aaron Bannert]
2570 *) Fix some restart/terminate problems in the worker MPM. Don't
2571 drop connections during graceful restart. [Jeff Trawick]
2573 *) Change the header merging behaviour in proxy, as some headers
2574 (like Set-Cookie) cannot be unmerged due to stray commas in
2575 dates. [Graham Leggett]
2577 *) Be more vocal about what AcceptMutex values we allow, to make
2578 us closer to how 1.3 does it. [Jim Jagielski]

2602 stack, rather than buffering the response into memory. [Greg Stein]
2604 *) Fix a hang condition with graceful restart and prefork MPM
2605 in the situation where MaxClients is very high but
2606 much fewer servers are actually started at the time of the

2652 *) Stop installing libtool for APR and tell APR where it should place
2653 its copy of libtool (via our installbuildpath layout variable).
2656 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
2657 when reading from a remote HTTP server in proxy. [Graham Leggett]
2659 *) Modify receive/send loop in proxy_http and proxy_ftp so that
2660 should it be necessary, the remote server socket is closed before
2661 transmitting the last buffer (set by ProxyIOBufferSize) to the
2662 client. This prevents the backend server from being forced to hang
2663 around while the last few bytes are transmitted to a slow client.
2664 Fix the case where no error checking was performed on the final
2665 brigade in the loop. [Graham Leggett]
2667 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
2668 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
2669 hours. [Graham Leggett, Bill Stoddard]
2671 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
2672 for a undefined variable. [Ian Holsman]
2674 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
2675 when we can't get a socket in the specified address family. We may
2676 have gotten back an IPv6 address first and yet our system is not
2677 configured to allow IPv6 sockets. [Jeff Trawick]

2684 [Dirk-Jan Faber <dirk-jan selwerd.nl>, Aaron Bannert,

2687 *) Rename the filter ordering priorities. The recent filtering fixes
2688 have showcased problems with their usage. Therefore, we need to
2689 rename them to increase the clarity. (CONTENT->RESOURCE,
2690 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
2692 Changes with Apache 2.0.33

2705 *) Change mod_ssl to always do a full startup/teardown on restarts.
2706 this allows mod_ssl to be added to a server that is already
2707 running and makes it possible to add/change certs/keys after the
2708 server has been started. [Doug MacEachern]
2710 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
2711 This pipe must be a bidirectional 'console' style relay, which
2712 mod_ssl prints all prompts to the pipe's stdin, and reads the
2713 passphrases from the pipe's stdout. [William Rowe]
2715 *) Fix bug where --sysconfdir and --localstatedir were being
2716 ignored. [Thom May <thom planetarytramp.net>, Aaron Bannert]
2719 *) Fix --enable-layout to work again. Caution: When specifying
2720 --enable-layout, common arguments like --prefix, --exec-prefix,
2721 etc. will be ignored and the settings from the layout will be
2722 used instead. [Thom May <thom planetarytramp.net>, Aaron Bannert]
2725 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
2726 regex pattern matching for the determination of which requests

2729 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
2731 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
2732 cruft in piped logs and rewritemap child processes.
2735 *) All instances of apr_lock_t have been removed and converted
2736 to one of the following new lock APIs: apr_thread_mutex.h,
2737 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
2738 use the apr_lock.h API, as the old API will soon be deprecated.
2741 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.

2749 lookup when adding filters to a request (via ap_add_*_filter_handle())
2750 [Ryan Morgan <rmorgan covalent.net>]
2752 *) Fix for multiple file buckets on Win32, where the first file

2756 *) Correct Win32 failure of mmap of a segment beyond start of the
2757 file; fixes large SSL and similar transfers. [William Rowe]
2760 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
2761 multi-process mode to not "daemonize" while detaching from the
2762 controlling terminal. This is necessary for Apache to work with
2763 process-management tools like AIX's "System Resource Controller"
2764 as well as Dan Bernstein's "daemontools".
2765 [Jos Backus <josb cncdsl.com>, Aaron Bannert]

2776 *) Some browsers ignore cookies that have been merged into a
2777 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
2778 are now unmerged in the http proxy before being sent to the
2779 client. [Graham Leggett]
2781 *) Fix a problem with proxy where each entry of a duplicated
2782 header such as Set-Cookie would overwrite and obliterate the
2783 previous value of the header, resulting in multiple header
2784 values (like cookies) going missing.

2817 *) Change the verbage on the ScoreBoardFile in our default configs.
2818 Also change the default to be commented out (unspecified) so we
2819 get anonymous shared memory by default. [Aaron Bannert]
2821 *) Implement new ScoreBoardFile directive logic. This affects how
2822 we create the scoreboard's shared memory segment. If the directive
2823 is present, a name-based segment is created. If the directive is
2824 not present, first an anonymous segment is created, and if that
2825 fails, a name-based segment is created from a file of the name
2826 DEFAULT_SCOREBOARD. This gives third-party applications the
2827 ability to access our scoreboard. [Aaron Bannert]
2829 *) Allow mod_deflate to work with non-GET requests and properly send
2830 Content-Lengths. [Sander Striker <striker apache.org>]
2832 *) Fix ap_directory_merge() to correctly merge configs when there is
2833 no <Directory /> block. [Justin Erenkrantz, William Rowe]
2835 *) Remove spurious debug messsages that are normal under HTTP
2836 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
2838 *) Fix a bug in mod_cgid that would prevent proper shutdown death
2839 of the cgid process. [Aaron Bannert]
2841 *) Add signal handling back in to the worker MPM for the one_process
2842 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
2844 *) Performance: Reuse per-connection transaction pools in the
2845 worker MPM, rather than destroying and recreating them. [Brian Pane]
2847 *) Remove all signals from the worker MPM's child process. Instead,
2848 the parent uses the Pipe of Death for all communication with the
2849 child processes. [Ryan Bloom]
2851 Changes with Apache 2.0.32
2853 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
2854 default if the directive is not specified. This mirrors older
2855 behavior without changes to the httpd.conf. [William Rowe]
2857 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
2858 the service, mpm and logging code, and bugs in apr_file_open_stderr
2859 and apr_file_dup2 functions. Win2K/XP services have no handles
2860 associated for stdin/out/err, which caused unpredictable behavior
2861 in the prior release. [William Rowe, Bill Stoddard]
2863 *) Win32: simplify the Application Event Log messages, since there isn't
2864 likely to be 'more information in the error log' before an error log
2865 has been opened. [William Rowe]
2867 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
2868 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
2870 *) Win32: apache -k shutdown now behaves like apache -k stop.
2873 *) Fix prefork to not kill the parent if a child hits a resource shortage
2874 on accept(). [Greg Ames]
2876 *) Fix seg faults that occur when what should be the httpd request line
2877 starts with \r\n followed by garbage. [Greg Ames]
2879 *) Allow statically linked support binaries with the new
2880 --enable-static-support flag, and enable this behavior in
2881 the binbuild script. Also add a new --enable-static-htdbm
2882 flag. [Aaron Bannert]
2884 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
2885 do only one stat() call when generating the directory listings.
2888 *) Fix resolve_symlink to save the original symlink name if known.
2891 *) Be a bit more sane with regard to CanonicalNames. If the user has
2892 specified they want to use the CanonicalName, but they have not
2893 configured a port with the ServerName, then use the same port that
2894 the original request used. [Ryan Bloom and Ken Coar]
2896 *) In core_input_filter, check for an empty brigade after
2897 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
2898 client says it will post some data but we get FIN before any
2899 data arrives. [Jeff Trawick]
2901 *) Not being able to bind to the socket is a fatal error. We should
2902 print an error to the console, and return a non-zero status code.
2903 With these changes, all of the Unix MPMs do that correctly.
2906 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
2907 through to CGI scripts. PR 9163
2908 [Brian Reid <breid customlogic.com>,
2909 Zvi Har'El <rl math.technion.ac.il>]
2911 *) binbuild.sh: Make sure that we use the expat from our source
2912 tree so that there aren't any surprises on the target machine.
2915 *) mod_cgid: Add retry logic for when the daemon can't fork fast
2916 enough to keep up with new requests. Start using
2917 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
2918 when we can't talk to the daemon. [Jeff Trawick]
2920 *) apxs: LTFLAGS envvar can override default libtool options. Try
2921 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
2922 the covers. [Jeff Trawick]
2924 *) The Location: response header field, used for external
2925 redirect, *must* be an absoluteURI. The Redirect directive
2926 tested for that, but RedirectMatch didn't -- it would allow
2927 almost anything through. Now it will try to turn an abs_path
2928 into an absoluteURI, but it will correctly varf like Redirect
2929 if the final redirection target isn't an absoluteURI. [Ken Coar]
2931 Changes with Apache 2.0.31
2933 *) Create the scoreboard (in the parent) in a global pool context,
2934 so it survives graceful restarts. This fixes a SEGV during
2935 graceful restarts. [Aaron Bannert]
2937 *) Add a timeout option to the proxy code 'ProxyTimeout'
2940 *) FTP directory listings are now always retrieved in ASCII mode.
2941 The FTP proxy properly escapes URI's and HTML in the generated
2942 listing, and escapes the path components when talking to the FTP
2943 server. It is now possible to browse the root directory by using
2944 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
2945 Also, the last path component may contain wildcard characters
2946 '*' and '?', and if they do, a directory listing is created instead
2947 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
2950 *) Added single-listener unserialized accept support to the
2951 worker MPM [Brian Pane]
2953 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
2954 the incoming host header through to the proxied server
2955 [Geoff <g.russell ieee.org>]
2957 *) New Directive Option for ProxyPass. It now can block a location
2958 from being proxied [Jukka Pihl <jukka.pihl entirem.com>]
2960 *) Don't let the default handler try to serve a raw directory. At
2961 best you get gibberish. Much worse things can happen depending
2962 on the OS. [Jeff Trawick]
2964 *) Change the pre_config hook to return a value. Modules can now emit
2965 an error message and then cause the server to quit gracefully during
2966 startup. This required a bump to the MMN. [Aaron Bannert]
2968 *) Fix some unix socket descriptor leaks in the handler side of
2969 mod_cgid (the part that runs in the server process). Whack a
2970 silly "close(-1)" in the handler too. [Jeff Trawick]
2972 *) Change the pre_mpm hook to return a value, so that scoreboard
2973 init errors percolate up to code that knows how to exit
2974 cleanly. This required a bump to the MMN. [Jeff Trawick]
2976 *) Add the socket back to the conn_rec and remove the create_connection
2977 hook. The create_connection hook had a design flaw that did not
2978 allow creating connections based on vhost info. [Bill Stoddard]
2980 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
2981 Resolves the common case of using negotation to resolve the request
2982 /script/foo for /script.cgi/foo. [William Rowe]
2984 *) Added new functions ap_add_(input|output)_filter_handle to
2985 allow modules to bypass the usual filter name lookup when
2986 adding hard-coded filters to a request [Brian Pane]
2988 *) caching should now work on subrequests (still very experimental)
2991 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
2993 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
2996 *) Refactor ap_rgetline so that it does not use an internal brigade.
2997 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
2999 *) Remove mod_auth_db. [Justin Erenkrantz]
3001 *) Do not install unnecessary pcre headers like config.h and internal.h.
3002 [Joe Orton <joe manyfish.co.uk>]
3004 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
3005 (as it does for a normal request). quick_handled sub-requests now work
3006 in mod-include [Ian Holsman]
3008 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
3009 'CONTENT' one, as it needs to run AFTER all content headers
3011 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
3014 *) Split out blocking from the mode in the input filters.
3017 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
3019 *) Cause Win32 to capture all child-worker process errors in
3020 Apache to the main server error log, until the child can
3021 open its own error logs. [William Rowe]
3023 *) HPUX 11.*: Do not kill the child process when accept()
3024 returns ENOBUFS on HPUX 11.*. (ported from th 1.3 patch)
3025 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, Bill Stoddard]
3027 *) Fix a problem in the parsing of the <Proxy foo> directive.
3030 *) rewrite of mod_ssl input filter for better performance and less
3031 memory usage [Doug MacEachern]
3033 *) allow quick_handler to be run on subrequests. [Ian Holsman]
3035 *) mod_dav now asks its provider to place content directly into the
3036 filter stack when handling a GET request. The mod_dav/provider
3037 API has changed, so providers need to be updated. [Greg Stein]
3039 *) Clear the output socket descriptor in unixd_accept() to make sure
3040 we don't supply a bogus socket to the caller if the accept fails.
3041 This caused problems with the worker MPM, which tried to process
3042 the returned socket if it was non-NULL. [Brian Pane]
3044 *) Move a check for an empty brigade to the start of core input filter
3045 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
3047 *) Add FileETag directive to allow configurable control of what
3048 data are used to form ETag values for file-based URIs. MMN
3049 bumped to 20020111 because of fields added to the end of
3050 the core_dir_config structure. [Ken Coar]
3052 *) Fix a segfault in mod_rewrite's logging code caused by passing the
3053 wrong config to ap_get_remote_host(). [Jeff Trawick]
3055 *) Allow mod_cgid to work from a binary distribution install by
3056 using 755 for the permissions on the log directory instead of
3059 *) Fixed a segfault that happened during graceful shutdown (or when
3060 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
3062 *) Split all Win32 modules [excluding the core components mod_core,
3063 mod_so, mod_win32 and the winnt mpm] into individual loadable
3064 modules, so the administrator may individually disable the former
3065 compiled-in modules by simply commenting out their LoadModule
3066 directives. [William Rowe]
3068 *) Saved Win32 module authors and porters many future headaches, by
3069 duplicating the appropriate .h files such as os.h into the include
3070 directory, including in the build tree. [William Rowe]
3072 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
3073 Use SSL functions/macros instead of directly dereferencing SSL
3074 structures wherever possible.
3075 Add type-casts for the cases where functions return a generic pointer.
3076 Add $SSL/include to configure search path.
3077 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3079 *) Moved several pointers out of the shared Scoreboard so it is
3080 more portable, and will present the vhost name across server
3081 generation restarts. [William Rowe]
3083 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
3086 Changes with Apache 2.0.30
3088 *) Fix the main bug for FreeBSD and threaded MPM's. There are
3089 still issues (see STATUS) but at least the server will now
3090 run without crashing the machine.
3091 [David Reid, Aaron Bannert, Justin Erenkrantz]
3093 *) Fix a typo in mod_deflate's m4 config section.
3094 [albert chin <china thewrittenword.com>]
3096 *) Fix a couple of mod_proxy problems forwarding HTTP connections
3097 and handling CONNECT:
3098 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
3099 (2) Proxy failed to connect when the first IP address returned by
3100 the resolver was unreachable but a secondary IP address was.
3103 *) Fix the module identifer as shown in the docs for various core
3104 modules (e.g., the identifer for mod_log_config was previously
3105 listed as config_log_module). PR #9338
3106 [James Watson <ap2bug sowega.org>]
3108 *) Fix LimitRequestBody directive by placing it in the HTTP
3109 filter. [Justin Erenkrantz]
3111 *) Fix mod_proxy seg fault when the proxied server returns
3112 an HTTP/0.9 response or a bogus status line.
3115 *) Prevent mod_proxy from truncating one character off the
3116 end of the status line returned from the proxied server.
3117 [Adam Sussman, Bill Stoddard]
3119 *) Eliminate loop in ap_proxy_string_read().
3120 [Adam Sussman, Bill Stoddard]
3122 *) Provide $0..$9 results from mod_include regex parsing.
3125 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
3127 *) Introduced the ForceLanguagePriority directive, to prevent
3128 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
3129 when using Multiviews. [William Rowe]
3131 *) Fix a problem which prevented mod_cgid and suexec from working
3132 together reliably [Greg Ames]
3134 *) Remove the call to exit() from within mod_auth_digest's post_config
3135 phase. [Aaron Bannert]
3137 *) Fix a problem in mod_auth_digest that could potentially cause
3138 problems with initialized static data on a system that uses DSOs.
3141 *) Fix a segfault in the worker MPM that could happen during
3142 child process exits. [Brian Pane, Aaron Bannert]
3144 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
3146 *) Fix matching of vhosts by ip address so we find IPv4
3147 vhost address when target address is v4-mapped form of
3148 that address. [Jeff Trawick]
3150 *) More performance tweaks to the BNDM string-search algorithm
3151 used to find "<!--#" tokens in mod_include [Brian Pane]
3153 *) Miscellaneous small performance fixes: optimized away various
3154 string copy operations and removed large temp buffers from
3155 the stack [Brian Pane]
3157 *) Fixed startup segfault that occurred when a VirtualHost
3158 directive had a port but no address [Brian Pane]
3160 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
3162 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
3163 if oslevel < WINNT. This should fix several problems reported
3164 Against 2.0.28 on Windows 98 [Bill Stoddard]
3166 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
3167 to fail. [Bill Stoddard]
3169 *) Change core code to allow an MPM to set hard thread/server
3170 limits at startup. prefork, worker, and perchild MPMs now have
3171 directives to set these limits. [Jeff Trawick]
3173 *) Win32: The async AcceptEx() event should be autoreset upon
3174 successful completion of a wait (WaitForSingleObject). This
3175 eliminates a number of spurious
3176 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
3179 *) Move any load library path environment variables out of
3180 apachectl and into a separate environment variable file which
3181 can be more easily tailored by the admin. The environment
3182 variable file as built by Apache may have additional system-
3183 specific settings. For example, on OS/390 we tailor the heap
3184 settings to allow lots of threads. [Jeff Trawick]
3186 *) Use the new APR pool code to reduce pool-related lock
3187 contention in the worker MPM. [Sander Striker]
3189 *) The POD no longer assumes the child is listening on 127.0.0.1
3190 and now pulls the first hostname in the list of listeners to
3191 perform the dummy connect on. This fixes a bug when the user
3192 had configured the Listen directive for an IP other than
3193 127.0.0.1. This would result in undead children and error
3194 messages such as "Connection refused: connect to listener".
3197 *) The worker MPM now respects the LockFile setting, needed to
3198 avoid locking problems with NFS. [Jeff Trawick]
3200 *) Fix segfault when worker MPM receives SIGHUP.
3201 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
3203 *) Fix bug that could potentially prevent the perchild MPM from
3204 working with more than one vhost/uid. [Aaron Bannert]
3206 *) Change make install and apxs -i processing of DSO modules to
3207 perform special handling on platforms where libtool doesn't install
3208 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
3209 which prevented standard LoadModule statements from working.
3212 *) Whenever mod_so is enabled (not just when there are DSOs for
3213 our modules), do whatever special magic is required for compiling/
3214 loading third-party modules. This allows third-party DSOs to
3215 be used on an AIX build when there were no built-in modules
3216 built as DSOs. (This should help on OS/390 and BeOS as well.)
3219 *) Allow apxs to be used to build DSOs on AIX without requiring the
3220 user to hard-code the list of import files. (This should help
3221 on OS/390 and BeOS as well.) [Jeff Trawick]
3223 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
3224 PR 8563, 8919 [William Rowe]
3226 *) Get binary builds working when libapr and libaprutil are built
3229 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
3230 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar pacbell.net>,
3231 Gary Hook <ghook us.ibm.com>, Victor Orlikowski, Jeff Trawick]
3233 *) Fix the handling of SSI directives in which the ">" of the
3234 terminating "-->" is the last byte in a file [Brian Pane]
3236 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
3237 message that we had back in apache-1.3 and still have scattered
3238 throughout our docs. [Aaron Bannert]
3240 *) Prevent the Win32 port from continuing after encountering an
3241 error in the command line args to apache. [William Rowe]
3243 *) On a error in the proxy, make it write a line to the error log
3246 *) Various mod_ssl performance improvements [Doug MacEachern]
3248 Changes with Apache 2.0.29
3250 *) Add buffering in core_output_filter to ensure that long
3251 lists of small buckets don't cause small packet writes.
3252 [Brian Pane, Ryan Bloom]
3254 *) Fix the installation target to make sure that the manual is
3255 installed in the correct location.
3256 [Yoshifumi Hiramatsu <hiramatu boreas.dti.ne.jp> and
3257 Gomez Henri <hgomez slib.fr>]
3259 *) Fix the cmd command for mod_include. When we are processing
3260 a cmd command, we do not want to use the r->filename to set
3261 the command name. The command comes from the SSI tag. To do this,
3262 I added a variable to the function that builds the command line
3263 in mod_cgi. This allows the include_cmd function to specify
3264 the command line itself. [Ryan Bloom]
3266 *) Change open_logs hook to return a value, allowing you
3267 to flag a error while opening logs
3268 [Ian Holsman, Doug MacEachern]
3270 *) Change post_config hook to return a value, allowing you
3271 to flag a error post config
3272 [Ian Holsman, Jeff Trawick]
3274 *) Allow SUEXEC_BIN (the path to the suexec binary that is
3275 hard-coded into the server) to be specified to the configure
3276 script by the --with-suexec-bin parameter. [Aaron Bannert]
3278 *) Fix segv in worker MPM following accept on pipe-of-death
3281 *) Add mod_deflate to experimental.
3282 [Ian Holsman, Justin Erenkrantz]
3284 *) Bail out at configure time if an invalid MPM was specified.
3285 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
3287 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
3288 configured [John Sterling <sterling covalent.net>]
3290 *) Fix apxs to use sbindir. [Henri Gomez <hgomez slib.fr>]
3292 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
3294 *) Optimization for the BNDM string-search function in
3295 mod_include. [Brian Pane]
3297 *) Fixed the behavior of the XBitHack directive.
3298 [Taketo Kabe <kabe sra-tohoku.co.jp>, Cliff Woolley] PR#8804
3300 *) The threaded MPM for Unix has been removed. Use the worker
3301 MPM instead. [various]
3303 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
3304 in logging the error from a failed DNS lookup. [Jeff Trawick]
3306 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
3309 *) Get mod_cgid killed when a MPM exits due to a fatal error.
3312 *) Fix a file descriptor leak in mod_include. When we include a
3313 file, we use a sub-request, but we didn't destroy the sub-request
3314 immediately, instead we waited until the original request was
3315 done. This patch closes the sub-request as soon as the data is
3316 done being generated. [Brian Pane <bpane pacbell.net>]
3318 *) Allow modules that add sockets to the ap_listeners list to
3319 define the function that should be used to accept on that
3320 socket. Each MPM can define their own function to use for
3321 the accept function with the MPM_ACCEPT_FUNC macro. This
3322 also abstracts out all of the Unix accept error handling
3323 logic, which has become out of synch across Unix MPMs.
3326 *) Fix a bug which would cause the response headers to be omitted
3327 when sending a negotiated ErrorDocument because the required
3328 filters were attached to the wrong request_rec.
3329 [John Sterling <sterling covalent.net>]
3331 *) Remove commas from the end of the macros that define
3332 directives that are used by MPMs. Prior to this patch,
3333 you would use these macros without commas, which was unlike
3334 the macros for any other directives. Now, the caller provides
3335 the comma rather than the macro providing it. This makes
3336 the macros look more like the rest of the directives.
3337 [Ryan Bloom and Cliff Woolley]
3339 *) Add 'redirect-carefully' environment option to disable sending
3340 redirects under special circumstances. This is helpful for
3341 Microsoft's WebFolders when accessing a directory resource via
3342 DAV methods. [Justin Erenkrantz]
3344 *) Begin to abstract out the underlying transport layer.
3345 The first step is to remove the socket from the conn_rec,
3346 the server now lives in a context that is passed to the
3347 core's input and output filters. This forces us to be very
3348 careful when adding calls that use the socket directly,
3349 because the socket isn't available in most locations.
3352 *) Really reset the MaxClients value in worker and threaded
3353 when the configured value is not a multiple of the number
3354 of threads per child. We said we did previously but we
3355 forgot to. [Jeff Trawick]
3357 *) Add Debian layout. [Daniel Stone <daniel sfarc.net>]
3359 *) If shared modules are requested and mod_so is not available,
3360 produce a fatal config-time error. [Justin Erenkrantz]
3362 *) Improve http2env's performance by cutting the work it has to
3363 do. [Brian Pane <bpane pacbell.net>]
3365 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
3366 [Brian Pane <bpane pacbell.net>]
3368 Changes with Apache 2.0.28
3370 *) Fix infinite loop in mod_cgid.c.
3371 [Dale Ghent <daleg elemental.org>, Brian Pane <bpane pacbell.net>]
3373 *) When no port is given in a "ServerName host" directive, the
3374 server_rec->port is now set to zero, not 80. That allows for
3375 run-time deduction of the correct server port (depending on
3376 SSL/plain, and depending also on the current setting of
3377 UseCanonicalName). This change makes redirections
3378 work, even with https:// connections. As in Apache-1.3, the
3379 connection's actual port number is never used, only the ServerName
3380 setting or the client's Host: setting. Documentation updated
3381 to reflect the change. [Martin Kraemer]
3383 *) Add a '%{note-name}e' argument to mod-headers, which works in
3384 the same way as mod_log_confg. [Ian Holsman]
3386 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
3387 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
3388 MPMs. [Cliff Woolley]
3390 *) Introduce htdbm, a user management utility for db/dbm authorization
3391 databases. [Mladen Turk <mturk mappingsoft.com>]
3393 *) Optimize usage of strlen and strcat in ap_directory_walk.
3394 [Brian Pane <bpane pacbell.net>]
3396 Changes with Apache 2.0.27
3398 *) Introduce an Apache mod_ssl initial configuration template
3399 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
3401 *) Fixed a memory leak in the getline parsing code that could
3402 be triggered by arbitrarily large header lines. Requests
3403 from the core input filter for single lines are now limited
3404 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
3406 *) Fix a truncation bug in how we print the port on the Via: header.
3407 The routine that prints the Via: header now takes a length for
3408 the port string. [Zvi Har'El <rl math.technion.ac.il>]
3410 *) Some syntax errors in mod_mime_magic's magic file can result
3411 in a 500 error, which previously was unlogged. Now we log the
3412 error. [Jeff Trawick]
3414 *) Add the support/checkgid helper app, which checks the run-time
3415 validity of group identifiers usable in the Group directive.
3418 *) Various --enable-so options have been fixed: --enable-so is
3419 treated as "static"; explicit --enable-so=shared issues an error;
3420 and explicit --enable-so fails with error on systems without
3421 APR_HAS_DSO. [Aaron Bannert]
3423 *) Fix a segfault in the core input filter when the client socket
3424 gets disconnected unexpectedly. [Cliff Woolley]
3426 *) Fix the reporting for child processes that die. This removes
3427 all of the non-portable W* macros from Apache.
3428 [Jeff Trawick and Ryan Bloom]
3430 *) Win32: Track and display "Parent Server Generation:" in
3431 mod_status output. The generation will be bumped at
3432 server graceful restart, when the child process exits
3433 by hitting MaxRequestsPerChild or if the child
3434 process exits abnormally. [Bill Stoddard]
3436 *) Win32: Fix problem where MaxRequestsPerChild directive was
3437 not being picked up in favor of the default. Enable
3438 the parent to start up a new child process immediately upon
3439 the old child starting shutdown.
3442 *) Fix some bungling of the remote port in rfc1413.c so that
3443 IdentityCheck retrieves the proper user id instead of failing
3444 and thus always returning "nobody."
3445 [Dick Streefland <Dick.Streefland xs4all.nl>]
3447 *) Introduced thread saftey for mod_rewrite's internal cache.
3448 [Brian Pane <bpane pacbell.net>]
3450 *) Simplified mod_env's directives to behave as most directives are
3451 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
3452 directive following that UnsetEnv within the same container.
3453 Also provides a runtime startup warning if a PassEnv configured
3454 environment value is undefined. [William Rowe]
3456 *) The worker MPM is now completely ported to APR's new lock API. It
3457 uses native APR types for thread mutexes, cross-process mutexes,
3458 and condition variables. [Aaron Bannert]
3460 *) Sync up documentation to remove all references to the now deprecated
3461 Port directive. [Justin Erenkrantz]
3463 *) Moved all ldap modules from the core to httpd-ldap sub-project
3466 *) Exit when we can't listen on any of the configured ports. This
3467 is the same behavior as 1.3, and it avoids having the MPMs to
3468 deal with bogus ap_listen_rec structures. [Jeff Trawick]
3470 *) Cleanup the proxy code that creates a request to the origin
3471 server. This change adds an optional hook, which allows modules
3472 to gain control while the request is created if the proxy module
3473 is loaded. The purpose of this hook is to allow modules to add
3474 input and/or output filters to the request to the origin. While
3475 I was at it, I made the core use this hook, so that proxy request
3476 creation uses some of the code from the core. This can still be
3477 greatly improved, but this is a good start. [Ryan Bloom]
3479 Changes with Apache 2.0.26
3481 *) Port the MaxClients changes from the worker MPM to the threaded
3484 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
3485 with the new input filtering system. [Justin Erenkrantz]
3487 *) Introduce the MultiviewsMatch directive, to allow the operator
3488 to be flexible in recognizing Handlers and Filters filename
3489 extensions as part of the Multiviews matching logic, strict with
3490 MultiviewsMatch NegotiatedOnly to accept only filename extentions
3491 that designate negotiated parameters, (content type, charset, etc.)
3492 or MultiviewsAll for the 1.3 behavior of matching any files, even
3493 if they have unregistered extensions. [William Rowe]
3495 *) Fixed the configure script to add a LoadModule directive to
3496 the default httpd.conf for any module that was compiled
3497 as a DSO. [Aaron Bannert <aaron clove.org>]
3499 *) rewrite mod_ssl input filtering to work with the new input filtering
3500 system. [Justin Erenkrantz]
3502 *) prefork: Don't segfault when we are able to listen on some but
3503 not all of the configured ports. [Jeff Trawick]
3505 *) Build mod_so even if no core modules are built shared.
3506 [Aaron Bannert <aaron clove.org>]
3508 *) Introduce ap_directory_walk rewrite (with further optimizations
3509 required) to adapt to the ap_process_request_internal() changes.
3510 Optimized so subrequests and redirects now reuse previous section
3511 merges, until we mismatch with the original directory_walk, and
3512 precomputed r->finfo results will cause directory_walk to skip
3513 the most expensive phases of the function. [William Rowe]
3515 *) Allow ApacheMonitor to connect to and control Apache on other
3516 WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>]
3518 *) Remove the Port directive. In it's place, the Listen directive
3519 is now a required directive, which tells Apache what port to
3520 listen on. The ServerName directive has also been extended
3521 to accept an optional port. If the port is specified to the
3522 ServerName, the server will report that port whenever it
3523 reports the port that it is listening on. This change was
3524 made to ease configuration errors that stem from having a Port
3525 directive, and a Listen directive. In that situation, the server
3526 would only listen to the port specified by the Listen command,
3527 which caused a lot of confusion to users. [Ryan Bloom]
3529 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
3530 build, as loadable modules. [William Rowe]
3532 *) Fix --enable-mods-shared processing. If most is specified,
3533 then all modules that can be compiled as shared modules are.
3534 [Aaron Bannert <aaron clove.org>]
3536 *) Update the mime.types file to map video/vnd.mpegurl to mxu
3537 and add commonly used audio/x-mpegurl for m3u extensions.
3538 [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht]
3540 *) Eliminate the depreciated r->content_language, in favor of the array
3541 r->content_languages introduced many years ago. Module authors must
3542 substantially overhaul their modules, so this needs to be upgraded
3543 if the module still relied on backwards-brokeness. [William Rowe]
3545 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
3548 *) Rewrite the input filtering mechanisms to consolidate and reorganize
3549 code. In short, core_input_filter does something now and
3550 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
3552 *) Update the Win32 build to re-absorb mod_proxy and family.
3555 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
3556 current SDK.) [William Rowe]
3558 *) Some style changes to the code that does ProxyErrorOverride. Fixed
3559 config merge behaviour. [Graham Leggett]
3561 *) Allow support programs to be compiled against a static version
3562 of libapr. This allows the smaller support programs to be
3563 relocated. [Aaron Bannert <aaron clove.org>]
3565 *) Update the mime.types file to the registered media types as
3566 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
3568 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
3569 number of clients that can connect at the same time, instead of
3570 specifying the maximum number of child processes.
3571 [Aaron Bannert <aaron clove.org>]
3573 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
3574 be consistent with 1.3. [Justin Erenkrantz]
3576 *) Cache apr_explode_localtime() value for 15 seconds.
3577 [Brian Pane <bpane pacbell.net>]
3579 *) Fix mod_include to not return ETag or Last-Modified headers.
3580 [Ian Holsman <ianh cnet.com>]
3582 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>]
3584 *) Eliminate the wasteful run-time conversion of method names from strings
3585 to numbers in places where the methods are known at compile time.
3586 [Brian Pane <bpane pacbell.net>]
3588 *) Turn the worker MPM's queue into a LIFO. This may
3589 improve cache-hit performance under some conditions.
3590 [Aaron Bannert <aaron clove.org>]
3592 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
3593 support it. [Justin Erenkrantz]
3595 *) Cleanup the worker MPM. We no longer re-use transaction
3596 pools. This incurs less overhead than shuffling the pools
3597 around so that they can be re-used. Remove one of the
3598 queue's condition variables. We just redefined the API to
3599 state that you can't try to add more stuff than you allocated
3600 segments for. [Aaron Bannert <aaron clove.org>]
3602 *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>]
3604 *) Fixed persistent connections when a request contains a body.
3607 *) mod_dav uses a new API to speak to the backend provider for dead
3608 property management. [Greg Stein]
3610 *) Remove the Win32 script-processing exception from mod_cgi, and
3611 roll build_command_line/build_argv_list into a unified, overrideable
3612 ap_cgi_build_command optional function. [William Rowe]
3614 *) Rewrite find_start_sequence to use a better search algorithm
3615 to find the start tag. [Justin Erenkrantz]
3617 *) Fix a seg fault in mod_include. When we are generating an
3618 internal redirect, we must set r->uri to "", not a bogus
3619 string, and not NULL. [Ryan Bloom]
3621 *) Optimized location_walk, so subrequests, redirects and second passes
3622 now reuse previous section merges on a <Location > by <Location >
3623 basis, until we mismatch with the original location_walk.
3626 *) Back out the 1.45 change to util_script.c. This change made
3627 us set the environment variable REQUEST_URI to the redirected
3628 URI, instead of the originally requested URI.
3629 [Taketo Kabe <kabe sra-tohoku.co.jp>]
3631 *) Make mod_include do lazy evaluation of potentially expensive to
3632 compute variables. [Brian Pane <bpane pacbell.net>]
3634 *) Fix logging of bytes sent for HEAD requests. %b and %B should
3635 log either - or 0, before this patch, they were both logging
3636 the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>]
3638 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
3639 than per character. [Brian Pane <bpane pacbell.net>]
3641 *) Normalize the primary request, redirects and sub-requests to
3642 run the same ap_process_request_internal for consistency in
3643 robustness, behavior and security. [William Rowe]
3645 *) Fix a segfault with mod_include when r->path_info is not set
3646 (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>]
3648 *) Add -X functionality back. This indicates to all MPMs and any other
3649 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
3651 *) Some initial support for the cygwin platform [prefork only].
3652 This is not to be confused with support for the WinNT/Win32
3653 platform, which is the recommended configuration for native
3654 Win32 users. The cygwin platform support is recommended for
3655 cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>]
3657 *) Changed syntax of Set{Input|Output}Filter. The list of filters
3658 must be semicolon delimited (if more than one filter is given.)
3659 The Set{Input|Output}Filter directive now overrides a parent
3660 container's directive (e.g. SetInputFilter in <Directory /web/foo>
3661 will override any SetInputFilter directive in <Directory /web>.)
3662 This new syntax is more consistent with Add{Input|Output}Filter
3663 directives defined in mod_mime. Also cures a bug in prior releases
3664 where the Set{Input|Output}Filter directive would corrupt the
3665 global configuration if the multiple directives were nested.
3668 *) Cured what's ailed mime for quite some time. If an AddSomething
3669 was given in the configuration (Language, Charset, Handler or
3670 Encoding) Apache would set the content type as given by AddType,
3671 but refused to check the mime.types file if AddType wasn't given
3672 for that specific extension. Setting the AddHandler for .html
3673 without setting the AddType text/html html would cause Apache to
3674 use the default content type. [William Rowe]
3676 *) Added some bulletproofing to memory allocation in the LDAP cache
3677 code. [Graham Leggett]
3679 Changes with Apache 2.0.25
3681 *) Move the installed /manual directory out of the /htdocs/ tree, so
3682 that it can be kept more independently from the remaining document
3683 root. The "Alias /manual ..." already allowed for easy projection
3684 into existing private document trees. [Martin Kraemer]
3686 *) Add specified user attributes to the environment when using
3687 mod_auth_ldap. This allows you to use mod_include to embed specified
3688 user attributes in a page like so:
3689 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
3692 *) Fix a performance problem with the worker MPM. We now create
3693 transaction pools once, and re-use them for each connection.
3694 [Aaron Bannert <aaron clove.org>]
3696 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
3697 of a 'handler' or 'filter', so that any filename extension that does
3698 not contribute to the negotiated metadata can't be served without
3699 an explicit request. E.g., if the .Z extension is associated with
3700 an unzip filter, the user request somefile.Z.html, mod_negotiation
3701 won't serve it. It can serve somefile.Z.html when somefile.Z is
3702 requested, since the .Z extension is explictly requested, if the
3703 .html extension is associated with ContentType text/html.
3706 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
3707 and corresponding AddOutputFilter syntax, to insert one or more
3708 filters by mod_mime filename extension processing.
3711 *) Fix a growing connection pool in core_output_filter() for
3712 keepalive requests. [Jeff Trawick]
3714 *) Moved split_and_pass_pretag_buckets back to being a
3715 macro at Ryans's request. Removed the return from it
3716 by setting and returning a return code instead. Updated
3717 the code to check the return code from the macro and
3718 do the right thing. [Paul J. Reder]
3720 *) Fix a segfault when a numeric value was received for Host:.
3723 *) Add a function ap_remove_input_filter. This is to match
3724 up with ap_remove_output_filter. [Ryan Bloom]
3726 *) Clean up location_walk, so that this step performs a minimum
3727 amount of redundant effort (it must be run twice, but it will no
3728 longer reparse all <Location > blocks when the request uri
3729 hadn't changed.) [William Rowe]
3731 *) Eliminate proxy: (and all other 'special') processing from the
3732 ap_directory_walk() phase. Modules that want to use special
3733 walk logic should refer to the mod_proxy map_to_location example,
3734 with it's proxy_walk and proxysection implementation. This makes
3735 either directory_walk flavor much more legible, since that phase
3736 only runs against real <Directory > blocks.
3739 *) SECURITY: Fix a security problem in mod_include which would allow
3740 an SSI document to be passed to the client unparsed.
3741 [Cliff Woolley, Brian Pane]
3743 *) Introduce the map_to_storage hook, which allows modules to bypass
3744 the directory_walk and file_walk for non-file requests. TRACE
3745 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
3746 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
3749 *) Add the ability for mod_include to add the INCLUDES filter
3750 if the file is configured for the server-parsed handler.
3751 This makes the configuration for .shtml files much easier
3752 to understand, and allows mod_include to honor Apache 1.3
3753 config files. Based on Doug MacEachern's patch to PHP
3754 to do the same thing. [Ryan Bloom]
3756 *) force OpenSSL to ignore process local-caching and to always
3757 get/set/delete sessions using mod_ssl's callbacks
3758 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
3759 Geoff Thorpe <geoff geoffthorpe.net>]
3761 *) Make the worker MPM shutdown and restart cleanly. This also
3762 cleans up some race conditions, and gets the worker using
3763 pools more cleanly. [Aaron Bannert <aaron clove.org>]
3765 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
3767 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3769 *) Fix for mod_include. Ryan's patch to check error
3770 codes put a return in the wrong place. Also, the
3771 include handler return code wasn't being checked.
3772 I don't like macros with returns, so I converted
3773 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
3774 [Paul J. Reder <rederpj raleigh.ibm.com>]
3776 *) fix segv in mod_mime if no AddTypes are configured
3777 [John Sterling <sterling covalent.net>]
3779 *) Enable ssl client authentication at SSL_accept time
3780 [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>]
3782 *) Fix a segfault in mod_include when the original request has no
3783 associated filename (e.g., we're filtering the error document for
3784 a bad URI). [Jeff Trawick]
3786 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
3788 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
3789 of httpd is started and shuts down due to socket conflict. Moving the
3790 call to ap_log_pid solves the problem.
3792 *) Changed the late-1.3 log_config substitution %c to %X, to log the
3793 status of the closed connection, as it conflicts with the far more
3794 common, historical ssl logging directive %...{var}c. [William Rowe]
3796 *) Added the common error/ tree to the build/install targets
3797 (similar to the common icons/ tree) for the multi-language error
3798 messages that Lars committed earlier. [William Rowe]
3800 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
3802 *) Added a default commented-out mod_ldap and mod_auth_ldap
3803 configuration to httpd-std.conf and httpd-win.conf
3806 *) Added documentation for mod_ldap and mod_auth_ldap.
3809 *) Enabled negative caching on attribute comparisons in the LDAP cache.
3810 Fixed a problem where the default cache TTL was set in milliseconds
3811 not microseconds causing the cache to time out almost immediately.
3814 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
3815 module code to follow APR. [Graham Leggett]
3817 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
3818 cleaned up when the connection pool pool is cleaned up.
3821 *) Fix a minor issue with Jeff Trawick's mod_include
3822 patch. Without this patch, the code will just allocate
3823 more bytes in get_combined_directive than are needed.
3826 *) Added the LDAP authentication module mod_auth_ldap.
3827 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3829 *) Added the LDAP cache and connection pooling module mod_ldap.
3830 [Dave Carrigan <dave rudedog.org>, Graham Leggett]
3832 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
3833 by allowing a module to disable itself if its prerequisites are not
3834 met. [Justin Erenkrantz]
3836 Changes with Apache 2.0.24
3838 *) Fix a couple of issues in mod_include when the tag appeared at
3839 offsets near 8192 in the file being parsed. [Jeff Trawick]
3841 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
3842 reached. [Jeff Trawick]
3844 *) Numerous improvements to the Win32 build system. Introduced command line
3845 builds without requiring .mak files for MSVC 6.0 and later versions.
3846 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
3849 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
3850 reporting of uninstalled services and other error conditions, and changed the
3851 default service name to Apache2. [William Rowe]
3853 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
3854 compatibility with existing Apache 1.3 Win32 Apache management utilites.
3855 [Mladen Turk <mturk mappingsoft.com>, William Rowe]
3857 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
3858 [William Rowe, Greg Ames]
3860 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
3861 and RemoveCharset directives. [William Rowe]
3863 *) The Unix MPMs other than perchild now allow child server
3864 processes to use the accept mutex when starting as root and
3865 using SysV sems for the accept mutex. Previously, this
3866 combination would lead to fatal errors in the child server
3867 processes. perchild can't use SysV sems because of security
3868 issues. [Jeff Trawick, Greg Ames]
3870 *) Added Win32 revision stamp resources to all http binaries
3871 (including modules/ and support/ tools.) PR7322 [William Rowe]
3873 *) Fix ap_rvprintf to support more than 4K of data at one time.
3874 [Cody Sherr <csherr covalent.net>]
3876 *) We have always used the obsolete/deprecated Netscape syntax
3877 for our tracking cookies; now the CookieStyle directive
3878 allows the Webmaster to choose the Netscape, RFC2109, or
3879 RFC2965 format. The new CookieDomain directive allows the
3880 setting of the cookie's Domain= attribute, too. PR #s 5006,
3881 5023, 5920, 6140 [Ken Coar]
3883 *) Tweak server/Makefile so that the rules for generating exports.c
3884 are compatible with make utilities which don't expand wildcards
3885 in a dependency list (e.g., OS/390 make, certain levels of GNU
3886 make). [Jeff Trawick]
3888 *) Install the SSL headers. [John Sterling <sterling covalent.net>]
3890 *) Begin to sanitize the MPM configuration directives. Now, all
3891 MPMs use the same functions for all common MPM directives. This
3892 should make it easier to catch all bugs in these directives once.
3893 [Cody Sherr <csherr covalent.net>]
3895 *) Close a major resource leak. Every time we had issued a
3896 graceful restart, we leaked a socket descriptor.
3899 *) Fix a problem with the new method code. We need to cast
3900 the 1 to an apr_int64_t or it will be treated as a 32-bit
3901 integer, and it will wrap after being shifted 32 times.
3902 [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>]
3904 *) Fix a bug in mod_expires. Previous to this patch, if you
3905 told mod_expires to add 604800 seconds to the last-modified
3906 time, it actually added 604800 usec's to the last-modified time,
3907 so that when looking at the response it looked like nothing
3908 had been done. The root of the problem was that we always compute
3909 time in usec's, but we ask users to input sec's. This means we
3910 need to convert to usec's before using those values.
3913 *) The worker MPM now handles shutdown and restart requests. It
3914 definitely isn't perfect, but we do stop the servers correctly.
3915 The biggest problem right now is that SIGHUP causes the server to
3916 just die. [Ryan Bloom]
3918 Changes with Apache 2.0.23
3920 *) Use the prefork MPM by default on Unix. [various]
3922 *) Added a systray icon monitor application for Win32.
3923 [Mladen Turk <mturk mappingsoft.com>]
3925 *) mod_rewrite: Fix the line ending on some non-Unix systems for
3926 messages written to the rewrite log.
3927 [Richard Labennett <rlabenn us.ibm.com>]
3929 *) All mod_autoindex query parsing is now quietly quashed with the
3930 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
3931 still drops the column sort <a href>'s for the column headers, but
3932 IgnoreClient is required to ignore these Query options entirely.
3935 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
3936 to allow the client to select plain, FancyIndexing or HTMLTable
3937 formatting, V=[0|1] to inhibit or enable version sorting, and
3938 P=pattern to return only specific files. The old Query Arguments
3939 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
3940 as before), and O=A|D for ordering ascending or descending.
3943 *) Fixed an error in mod_include's directive parsing routines which
3944 caused #if, #elif, and #else expressions containing backslashes
3945 to be improperly evaluated. [Cliff Woolley]
3947 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
3948 drop the icon column, SuppressRules to drop the <hr> elements,
3949 and HTMLTable to create rudimentary HTML table listings (implies
3950 FancyIndexing). [William Rowe]
3952 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
3953 from Apache 1.3.15. This is needed for two reasons, first, given
3954 multiple machines within a server farm, ETags and Last-Modified
3955 stamps won't correspond from machine to machine, and second, many
3956 Unixes don't capture changes to the date or time stamp of existing
3957 files, since these don't modify the dirent itself. [William Rowe]
3959 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
3960 and DirectoryWidth options from Apache 1.3.10.
3961 [William Rowe, Ken Coar]
3963 *) Eliminated FancyIndexing directive, deprecated early in Apache
3964 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
3966 *) mod_autoindex now excludes any file names that would result in
3967 an error, other than a success or redirect. Also optimized
3968 the parent directory, always included except in the URI '/'.
3971 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
3972 negotiated index pages, and prevent the server from defaulting
3973 to an autoindex of the directory. mod_negotiation will now die
3974 with a 500 Internal Error if it could match some filenames
3975 (e.g. for mod_dir) but none can be served. mod_negotation now
3976 refuses to serve any file with an extention that mod_mime doesn't
3977 recognize, and wasn't part of the request. [William Rowe]
3979 *) Eliminate mod_cgi's handling of .exe files without the .exe file
3980 extension. This is already handled by multiviews, if the admin
3981 wishes to AddHandler .exe or define a content type handler and
3982 associate .exe files with that content type. Multiviews must be
3983 enabled to allow these to be served. [William Rowe]
3985 *) Speed up the server's response to a spike in incoming workload
3986 or restarts by assigning empty scoreboard slots to new processes
3987 when they are available. [Greg Ames]
3989 *) Add a handler to mod_includes.c. This handler is designed to
3990 implement the XbitHack directive. This can't be done with a
3991 fixup, because we need to check the content-type, which is
3992 only available in the handler phase. [Ryan Bloom]
3994 *) Make the includes filter check return codes from filters lower in
3995 the filter chain. If a lower level filter returns an error, then
3996 the request needs to stop immediately. This allows mod_include to
3997 stop parsing data once a lower filter recognizes an error.
4000 *) Add the ability to extend the methods that Apache understands
4001 and have those methods <limit>able in the httpd.conf. It uses
4002 the same bit mask/shifted offset as the original HTTP methods
4003 such as M_GET or M_POST, but expands the total bits from an int to
4004 an ap_int64_t to handle more bits for new request methods than
4005 an int provides. [Cody Sherr <csherr covalent.net>]
4007 *) Fix broken mod_mime behavior in merging its arguments. Possible
4008 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
4010 *) Solve many mod_ssl porting issues (too many to detail) with
4011 help from the whole team, but most notably [Ralf S. Engelschall,
4012 Madhusudan Mathihalli <madhusudan_mathihalli hp.com>,
4013 Doug MacEachern, William Rowe, Cliff Woolley]
4015 *) More stall fixes for the threaded & worker mpm's.
4016 Make mod_status output more accurate. Don't
4017 count workers in processes which aren't actively
4018 serving requests. [Greg Ames]
4020 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
4022 *) Add a single listener/multiple worker MPM. This MPM is
4023 definately not fully correct, but it allows us to solve many
4024 of the problems that exist in the threaded MPM. This is a
4025 modified version of the threaded MPM. [Ryan Bloom]
4027 *) Improve content generation throughout Apache, providing closer
4028 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
4029 Transitional specifications. [William Rowe]
4031 Changes with Apache 2.0.22
4033 *) Fix a problem where the threaded MPM stalls after restarts or
4034 segfaults. Also prevent multiple active processes from using
4035 the same scoreboard slot. [Greg Ames]
4037 *) Apache/Win32 now fills in the service description with Apache's
4038 server version string, including loaded and advertised modules.
4041 *) Improved support for the Win32 build, to recover gracefully from
4042 missing apr or apr-util directories or the awk interpreter,
4043 create the proper cgi-bin examples, including a test-cgi.bat, and
4044 fix the perl shebang line for printenv.pl, when installing from
4045 the build environment. [William Rowe]
4047 *) Fix a segfault in threaded.c caused by passing uninitialized
4048 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
4050 *) Use new APR number conversion functions to reduce CPU consumption
4051 when setting the content length, and in mod_log_config.
4054 *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp>
4055 where HEAD response headers were being repeated twice for
4056 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
4057 problem in the http_header filter was exposed by the recent rewrite
4058 of the content_length filter. [Taketo Kabe, Bill Stoddard]
4060 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
4061 restarts. A garbage pointer to a vhost's server_rec from the
4062 previous generation was being left around under certain
4063 conditions. [Greg Ames]
4065 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
4066 used to appear as '(none', without the closing paren.
4067 [Günter Knauf <eflash gmx.net>]
4069 *) Improve the exports generating awk script. In the past, we had
4070 work around problems in the awk script by avoiding some #if and
4071 #ifdefs. This has bitten us many times in generating the exports.c
4072 file. This improvement allows corrects the header file parsing.
4073 [Sander Striker <striker apache.org>]
4075 Changes with Apache 2.0.21
4077 *) Resolve the Win32 htpasswd bug, where a file that existed would be
4078 overwritten, regardless of the -c flag.
4079 [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>]
4081 *) Introduce connection sub-pools into ab. Truncating the lifetime
4082 of these allocations means that ab no longer perpetually grows
4083 its working set, running out of memory on large request attempts.
4086 *) Make scoreboard creation a hook. This allows management
4087 modules to have access to the scoreboard at the time that it is
4088 created, and at every restart request.
4089 [Cody Sherr <csherr covalent.net>]
4091 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
4092 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
4093 daemon index actually used in the scoreboard. I also
4094 updated the pertinent calls. [Paul J. Reder]
4096 *) Win32: Prevent listening sockets from being inherited by
4097 the Apache child process, CGI scripts, rotatelog process
4098 etc. If the Apache child process segfaults, any processes
4099 that the child started are not reaped. Prior to this fix,
4100 these processes inherited the listening sockets which sometimes
4101 prevented the restarted Apache child process from accepting
4102 connections (ie, the server would hang).
4105 *) Provide vhost and request strings when ExtendedStatus is on.
4108 *) Fix some issues with the pod and prefork: check the pod *after*
4109 processing a connection so that a server processing a time-
4110 consuming request bails out as soon as practical; when the
4111 parent process wakes up a server process via connect(), use an
4112 APR timeout on the connect() so that we don't hang for a long
4113 time if there aren't server processes around to do accept().
4114 [Jeff Trawick, Greg Ames]
4116 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
4117 spends a lot of time in apr_table_get calls. Using the default
4118 httpd.conf, the tables for languages and charsets are somewhat
4119 large, so the time spent scanning them on each request is
4120 significant. Replacing the tables with hash tables provides
4121 a nice speedup. [Brian Pane <bpane pacbell.net>]
4123 *) Add two functions to allow modules to access random parts of the
4124 scoreboard. This allows modules compiled for one MPM to access the
4125 scoreboard, even if it the server was compiled for another MPM.
4126 [Harrie Hazewinkel <harrie covalent.net>]
4128 Changes with Apache 2.0.20
4130 *) Fix problem in content-length filter where the filter would
4131 buffer all the output from a CGI before sending any bytes
4132 down the filter stack to the network. This problem would cause
4133 significant memory consumption if the CGIs generated
4134 lots of bytes. [Bill Stoddard]
4136 *) Get non-blocking CGI pipe reads working with the bucket brigades.
4139 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
4142 *) Fix a bug in the threaded MPM that would cause it to kill off all
4143 workers immediately after starting if the number of workers started
4144 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
4146 Changes with Apache 2.0.19
4148 *) Fix problem with threaded MPM. The problem was that if each child
4149 process was busy serving a single long-lived request and the server
4150 was sent a graceful restart signal, the server would stop serving
4151 requests. This would happen because each child process would wait to
4152 die until the last thread was done, and the parent wouldn't spawn any
4153 new children until a process died. Now, the parent looks at the fact
4154 that the children are dying gracefully, and starts new children.
4155 Those new children only start enough threads to compliment the number
4156 of threads in the other child process that shares the same spot in
4157 the scoreboard. In this way, we make sure to never go over
4158 MaxClients. [Ryan Bloom]
4160 *) modified mod_negotiation and mod_autoindex to speed up by almost a
4161 factor of two on apr_dir_read()-enhanced platforms, such as Win32
4162 and OS2, by calling ap_sub_request_lookup_dirent() with the results
4163 already provided by apr_dir_read(). [William Rowe]
4165 *) mod_file_cache is now more robust to filtering and serves requests
4166 slightly more efficiently. [Cliff Woolley]
4168 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
4169 Module was calling ap_rwrite() followed by ap_rflush() but the
4170 served content was not being displayed in the browser. Inspection
4171 of the output stream revealed that the first data chunk was
4172 missing the trailing CRLF required by the RFC. [Bill Stoddard]
4174 *) apxs no longer generates ap_send_http_header() in the example handler
4176 *) Fix an ab problem which could cause a divide-by-zero exception
4177 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
4178 [Ian Holsman <ianh cnet.com>]
4180 *) Solve case-insensitive platforms' confusion about negotiated
4181 filenames, allowing files of differnt case to match in choosing
4182 the document to serve. [William Rowe]
4184 *) Fix brokenness when ThreadsPerChild is higher than the built-in
4185 limit. We left ap_threads_per_child at the higher value which
4186 led to segfaults when doing certain scoreboard operations.
4189 *) Fix seg faults and/or missing output from mod_include. The
4190 default_handler was using the subrequest pool for files and
4191 MMAPs, even though the associated APR structures typically
4192 live longer than the subrequest. [Greg Ames]
4194 *) Extend mod_setenvif to support specifying regular expressions
4195 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
4196 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
4197 will cause HAVE_TS to be set if any of the request headers begins
4198 with "TS" and has a value that begins with any character in the
4199 set [a-z]. [Bill Stoddard]
4201 *) httpd children now re-bind themselves to a random CPU on
4202 multiprocessor systems on AIX via bindprocessor() in 2.0.
4203 [Victor J. Orlikowski]
4205 *) Fix htdigest. It would go into a loop in getline when adding
4206 a second user. [Bill Stoddard]
4208 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
4210 *) Automatically generate httpd.exp for AIX.
4211 DSOs now work again on AIX in 2.0
4212 [Victor J. Orlikowski]
4214 *) Add a new request hook, error_log. This phase allows modules
4215 to act on the error log string _after_ it has been written
4216 to the error log. The goal for this hook is to allow monitoring
4217 modules to send the error string to the monitoring agent.
4220 *) Modify mod_echo to make it use filters for input and output.
4221 [Ryan Morgan <rmorgan covalent.net>]
4223 *) Extend mod_headers to support conditional driven Header
4224 add, append and set. Use SetEnvIf to set an envar and conditionally
4225 add/append/set headers based on this envar thusly:
4227 SetEnvIf TSMyHeader value HAVE_TSMyHeader
4228 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
4230 If the request contains header "TSMyHeader: value" then header
4231 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
4234 *) Extend mod_headers to support using format specifiers on Header
4235 add, append and set header values. Two format specifiers are supported:
4237 %t - reports, in UTC microseconds since the epoch, when the
4238 request was received.
4240 %D - reports the time, in microseconds, between when the request was
4241 received and the response sent.
4244 Header add MyHeader "This request served in %D microseconds. %t"
4246 results in a header being added to the response that looks like this:
4248 MyHeader: This request served in D=5438 microseconds. t=991424704447256
4252 *) Fix reset_filter(). We need to be careful how we remove filters.
4253 If we set r->output_filters to NULL, we also have to reset the
4254 connection's filters. [John Sterling]
4256 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
4258 *) Add a check to ap_die() to make sure the filter stack is sane and
4259 contains the correct basic filters when an error occurs. This fixes
4260 a problem where headers are not being sent on error. [John Sterling]
4262 *) New Header directive 'echo' option. "Header echo regex" will
4263 cause any headers received on the request that match regex to be
4264 echoed to (included in) the response headers.
4267 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
4268 This prevented the inclusion of apr_compat.h. PR #7773
4269 [Oleg Broytmann <phd phd.pp.ru>]
4271 *) Moved util_uri to the apr-util library. This required a bunch of
4272 apr_name changes for the uri utility functions. [Justin Erenkrantz]
4274 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
4275 insert_filter phase so that other filters are not bypassed by default.
4278 *) Reimplement mod_headers as an output filter. mod_headers can now
4279 add custom headers to inbound requests using the RequestHeader directive
4280 and to responses using the same old Header directive. [Graham Leggett]
4282 Changes with Apache 2.0.18
4284 *) Fix command-line processing so that if a bad argument is specified
4285 Apache will exit. [Jeff Trawick]
4287 *) Change the make targets and rules to be consistent in all of the
4288 Apache-owned source trees. [Roy Fielding]
4290 *) Fix processing of the TRACE method. Previously we passed bogus
4291 parms to form_header_field() and it overlaid some vhost structures,
4292 resulting in a segfault in check_hostalias().
4293 [Greg Ames, Jeff Trawick]
4295 *) Win32: Add support for reliable piped logs. If the logging process
4296 goes down, Apache will automatically restart it. This function has
4297 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
4300 *) Do not start piped log processes during the config file
4301 preflight. This change also circumvents a problem on
4302 Windows where the rotatelog processes created during preflight
4303 was not getting cleaned up properly.
4306 *) add "Request Phase Participation" info to mod_info
4309 *) Make first phase changes to the scoreboard data structures in
4310 preparation for the rewriting of the scoreboard per my posted
4311 design notes. [Paul J. Reder]
4313 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
4314 and apr-util, allow it to be overridden by the configure command-line
4315 (default="--silent") and introduce LT_LDFLAGS to replace what we were
4316 formerly abusing as LTFLAGS. [Roy Fielding]
4318 *) Clean up the reporting of incorrect closing container tags.
4319 [Barrie Slaymaker <barries slaysys.com>]
4321 *) Simplify the configure process by moving all libtool stuff to APR
4322 and moving hints.m4 inline. [Roy Fielding]
4324 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
4325 of functions used by mod_proxy for export in the DLL
4326 [Ian Holsman <IanH cnet.com>]
4328 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
4329 request body from its stdin but no reqest body is being written to
4330 the cgi. [Jeff Trawick]
4332 *) mod_log_config: %c connection status incorrectly logged
4333 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
4336 *) Get mod_cern_meta working under Windows
4339 *) Create Files, and thus MMAPs, out of the request pool, not the
4340 connection pool. This solves a small resource leak that had us
4341 not closing files until a connection was closed. In order to do
4342 this, at the end of the core_output_filter, we loop through the
4343 brigade and convert any data we have into a single HEAP bucket
4344 that we know will survive clearing the request_rec.
4345 [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>,
4348 *) Completely revamp configure so that it preserves the standard make
4349 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
4350 the configure additions to EXTRA_* variables. Also, allow the user
4351 to specify NOTEST_* values for all of the above, which eliminates the
4352 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
4353 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
4354 avoid pointless duplications. Fix the order in which flags are given
4355 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
4356 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
4357 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
4358 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
4360 *) Get mod_tls to compile/work better on Windows. PR #7612
4361 [Bernhard Schrenk <b.schrenk improx.com>]
4363 *) Fix shutdown/restart hangs in the threaded MPM.
4364 [Jeff Trawick, Greg Ames, Ryan Bloom]
4366 *) Removed the keptalive boolean from conn_rec because it is now only
4367 used by a single routine and can be replaced by a local variable.
4368 [Greg Stein, Ryan Bloom, Roy Fielding]
4370 *) Patch prefork to put enough of the signal processing back in so that
4371 signals are all handled properly now. The previous patch fixed the
4372 deadlock race condition, but broke the user directed signal handling.
4373 This fixes it to work the way it did before my previous prefork patch
4374 (primarily, SIGTERM is now working).
4376 *) Change how input filters decide how much data is returned to the
4377 higher filter. We used to use a field in the conn_rec, with this
4378 change, we use an argument to ap_get_brigade to determine how much
4379 data is retrieved. [Ryan Bloom]
4381 *) Fix seg fault at start-up introduced by Ryan's change to enable
4382 modules to specify their own logging tags. mod_log_config
4383 registers an optional function, ap_register_log_handler().
4384 ap_register_log_handler() was being called by http_core before
4385 the directive hash table was created. This patch creates the
4386 directive hash table before ap_register_log_handler() is
4387 registered as an optional function.
4388 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4390 *) Add ap_set_int_slot() function
4391 [John K. Sterling <sterling covalent.net>]
4393 *) Under certain circumstances, Apache did not supply the
4394 right response headers when requiring authentication.
4395 [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114
4396 (This is a port of the change that went into Apache 1.3.19.)
4398 *) Allow modules to specify their own logging tags. This basically
4399 allows a module to tell mod_log_config that when %x is encountered
4400 a specific function should be called. Currently, x can be any single
4401 character. It may be more useful to make this a string at some point.
4404 Changes with Apache 2.0.17
4406 *) If a higher-level filter handles the byterange aspects of a
4407 request, then the byterange filter should not try to redo the
4408 work. The most common case of this happening, is a byterange
4409 request going through the proxy, and the origin server handles
4410 the byterange request. The proxy should ignore it.
4411 [Graham Leggett <minfrin sharp.fm>]
4413 *) Changed the threaded mpm to have child_main join to each of the
4414 worker threads to make sure the kids are all gone before child_main
4415 exits after a signal (cleanup from perform_idle_server_maintenance).
4416 This is an extension of Ryans recent commit to make the child_main
4419 *) Add more options to the ap_mpm_query function. This also allows MPMs to
4420 report if their threads are dynamic or static. Finally, this also
4421 implements a new API, ap_show_mpm, which returns the MPM that was
4422 required into the core. [Harrie Hazewinkel <harrie covalent.net>]
4424 *) Do not install the binaries from the support directory twice.
4425 [jun-ichiro hagino <itojun iijlab.net>]
4427 *) The ap_f* functions should flush data to the filter that is passed
4428 in, not the filter after the one passed in.
4429 [Ryan Morgan <rmorgan covalent.net>]
4431 *) Make ab work again by changing its native types to apr types and formats.
4432 [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4434 *) Move the byterange filter and all of the supporting functions back
4435 to the HTTP module. The byterange filter turned out to be very
4436 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
4438 *) Make clean, distclean, and extraclean consistently according to the
4439 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>]
4441 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
4442 This may have been causing problems stopping processes in the threaded
4445 *) Fix content-length in mod_negotiation to a long int representation.
4448 *) Remove BindAddress from the default config file.
4449 [<giles nemeton.com.au>]
4451 *) Allow module authors to add a module to their Apache build using
4452 --with-module, without re-running buildconf. The syntax is:
4453 --with-module=module_type:/path/to/module.c
4454 The configure script will copy the module.c file to
4455 modules/module_type, and it will be added to the relevant Makefiles.
4456 currently, this only works for static modules. [Ryan Bloom]
4458 *) Changes required to make prefork clean up idle children properly.
4459 There was a window during which a starting worker deadlocks when
4460 an idle cleanup arrives before it completes init. Apache then keeps
4461 trying to cleanup the same deadlocked worker forever (until higher
4462 pids come along, but it still will never reduce below the deadlocked
4463 pid). Thus the number of children would not reduce to the correct
4464 idle level. [Paul J. Reder]
4466 Changes with Apache 2.0.16
4468 *) Change the default installation directory to /usr/local/apache2,
4469 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
4471 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
4474 *) Get MaxRequestsPerChild working with the Windows MPM.
4477 *) Make generic hooks to work, with mod_generic_hook_import/export
4478 experimental modules. [Ben Laurie, Will Rowe]
4480 *) Fix segfaults for configuration file syntax errors such as
4481 "<Directory>" followed by "</Directory" and
4482 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
4484 *) Cleanup the --enable-layout option of configure. This makes
4485 us use a consistent location for the config.layout file, and it
4486 makes configure more portable.
4487 [jun-ichiro hagino <itojun iijlab.net>]
4489 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
4490 csv/gnuplot format, rudimentary ssl support and various other tweaks
4491 to make results more true to what is measured. The upshot of this it
4492 turns out that 'ab' has often underreported the true performance of
4493 apache. Often by a order of magnitude :-) See talk/paper of Sander
4494 Temme at April ApacheCon 2001 for details.
4495 [Dirk-Willem van Gulik]
4497 *) Clean up mod_cgid's temporary request pool. Besides fixing a
4498 storage leak this ensures that some unnecessary pipes are closed.
4501 *) Performance: Add quick_handler hook. This hook is called at the
4502 very beginning of the request processing before location_walk,
4503 translate_name, etc. This hook is useful for URI keyed content
4504 caches like Mike Abbott's Quick Shortcut Cache.
4507 *) top_module global variable renamed to ap_top_module [Perl]
4509 *) Move ap_set_last_modified to the core. This is a potentially
4510 controversial change, because this is kind of HTTP specific. However
4511 many protocols should be able to take advantage of this kind of
4512 information. I expect that headers will need one more layer of
4513 indirection for multi-protocol work, but this is a small step in
4514 the right direction. [Ryan Bloom]
4516 *) Enable mod_status by default. This matches what Apache 1.3 does.
4519 *) Add a ScriptSock directive to the default config file. This is
4520 only enabled when mod_cgid is used.
4521 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4523 Changes with Apache 2.0.15
4525 *) Untangled the buildconf script and eliminated the need for build's
4526 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
4527 libtool muck that is now under srclib/apr/build. [Roy Fielding]
4529 *) Win32: Don't accept more connections than we have worker threads
4533 *) Fix bug in the Unix threaded.c MPM that allowed child processes
4534 to fork() new child processes.
4537 *) SECURITY: Fix a major security problem with double-reverse lookup
4538 checking. Previously, a client connecting over IPv4 would not be
4539 matched properly when the server had an IPv6 listening socket.
4540 PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>]
4542 *) Change the way the beos MPM handles polling to allow it to stop and
4543 restart. Problem was the sockets being polled were being reset by
4544 the select call, so once it had accepted a connection it was no
4545 longer listening on the UDP socket we use for shutdown instructions.
4546 APR needs to be altered, patch on it's way. [David Reid]
4548 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
4549 on error exit from ap_getline(). Some other code got upset because
4550 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
4552 *) Handle ap_discard_request_body() being called more than once.
4553 [Greg Ames, Jeff Trawick]
4555 *) Get rid of an inadvertent close of file descriptor 2 in
4556 mod_mime_magic. [Greg Ames, Jeff Trawick]
4558 *) Add a hook, create_request. This hook allows modules to modify
4559 a request while it is being created. This hook is called for all
4560 request_rec's, main request, sub request, and internal redirect.
4561 When this hook is called, the r->main, r->prev, r->next
4562 pointers have been set, so modules can determine what kind of
4563 request this is. [Ryan Bloom]
4565 *) Cleanup the build process a bit more. The Apache configure
4566 script no longer creates its own helper scripts, it just
4568 [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>]
4570 *) Stop the forced downgrade of the connection to HTTP/1.0 for
4571 proxy requests. [Graham Leggett]
4573 *) Avoid using sscanf to determine the HTTP protocol number in
4574 the common case because sscanf is a performance hog. From
4575 Mike Abbot's Accelerating Apache patch number 6.
4576 [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard]
4578 *) SECURITY: Fix a security exposure in mod_access. Previously when
4579 IPv6 listening sockets were used, allow/deny-from-IPv4-address rules
4580 were not evaluated properly (PR #7407). Also, add the ability to
4581 specify IPv6 address strings with optional prefix length on Allow
4582 and Deny. [Jeff Trawick]
4584 *) Enhance rotatelogs so that a UTC offset can be specified, and
4585 the logfile name can be formatted using strftime(3). (Brought
4586 forward from 1.3.) [Ken Coar]
4588 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
4589 DuplicateHandle on an IOCompletionPort (a practice which
4590 MS "discourages"). The new model does not rely on associating
4591 the completion port with the listening sockets, thus the
4592 completion port can be completely managed within the child
4593 process. A dedicated thread accepts connections off the network,
4594 then calls PostQueuedCompletionStatus() to wake up worker
4595 threads blocked on the completion port.
4598 *) Bring forward the --suexec-umask option which allows the
4599 builder to preset the umask for suexec processes. [Ken Coar]
4601 *) Add a -V flag to suexec, which causes it to display the
4602 compile-time settings with which it was built. (Only
4603 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
4605 *) Mod_include should always unset the content-length if the file is
4606 going to be passed through send_parsed_content. There is no to
4607 determine if the content will change before actually scanning the
4608 entire content. It is far safer to just remove the C-L as long
4609 as we are scanning it. [Ryan Bloom]
4611 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
4612 request and not Proxy-Authenticate.
4613 [Graham Leggett <minfrin sharp.fm>]
4615 Changes with Apache 2.0.14
4617 *) Fix content-length computation. We ONLY compute a content-length if
4618 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
4619 or we already have all the data. [Ryan Bloom]
4621 *) Report unbounded containers in the config file. Previously, a typo
4622 in the </container> directive could result in the rest of the config
4623 file being silently ignored, with undesired defaults used.
4626 *) Make the old_write filter use the ap_f* functions for the buffering.
4629 *) Move more code from the http module into the core server. This
4630 is core code, basically the default handler, the default input
4631 and output filters, and all of the core configuration directives.
4632 All of this code is required in order for the server to work, with or
4633 without HTTP. The server is closer to working without the HTTP
4634 module, although there is still more to do. [Ryan Bloom]
4636 *) Fix a number of SGI compile warnings throughout the server. Fix some
4637 bad parameters to apr_bucket_read(). Fix a bad statement in
4638 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
4639 consistently; we were mixing apr_time_t and time_t in invalid ways
4640 before. In load_file(), call apr_dso_error() instead of
4641 apr_strerror() so that we get a more specific string on some platforms.
4642 PR #6980 [Jeff Trawick]
4644 *) Allow modules to query the MPM about it's execution profile. This
4645 query API can and should be extended in the future, but for now,
4646 max_daemons, and threading or forking is a very good start.
4647 [Jon Travis <jtravis covalent.net>]
4649 *) Modify mod_include to send blocks of data no larger than 9k.
4650 Without this, mod_include will wait until the whole file is parsed,
4651 or the first tag is found to send any data to the client.
4652 [Paul J. Reder <rederpj raleigh.ibm.com>]
4654 *) Fix mod_info, so that <Directory> and <Location> directives are
4655 not displayed twice when displaying the current configuration.
4656 [Ryan Morgan <rmorgan covalent.net>]
4658 *) Add config directives to override DEFAULT_ERROR_MSG and
4659 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
4660 [Dan Rench <drench xnet.com>]
4662 *) Get mod_info building and loading on Win32. [William Rowe]
4664 *) Begin to move protocol independant functions out of mod_http. The goal
4665 is to have only functions that are HTTP specific in the http directory.
4668 Changes with Apache 2.0.13
4670 *) Don't assume that there will always be multiple calls to the byterange
4671 filter. It is possible that we will need to do byteranges with only
4672 one call to the filter. [Ryan Morgan <rmorgan covalent.net>]
4674 *) Move the error_bucket definition from the http module to the
4675 core server. Every protocol will need this ability, not just
4678 Changes with Apache 2.0.12
4680 *) Modify mod_file_cache to save pre-formatted strings for
4681 content-length and last-modified headers for performance.
4682 [Mike Abbot <mja trudge.engr.sgi.com>]
4684 *) Namespace protect IOBUFSIZ since it is exposed in the API.
4685 [Jon Travis <jtravis covalent.net>]
4687 *) Use "Basic" authentication instead of "basic" in ab, as the spec
4688 says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>]
4690 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
4691 without ever filling it out. This fixes PR 7271.
4692 [Taketo Kabe <kabe sra-tohoku.co.jp> and
4693 Cliff Woolley <cliffwoolley yahoo.com>]
4695 *) Add a couple of GCC attribute tags to printf style functions.
4696 [Jon Travis <jtravis covalent.net>]
4698 *) Add the correct language tag for interoperation with the Taiwanese
4699 versions of MSIE and Netscape. [Clive Lin <clive CirX.ORG>] PR#7142
4701 *) Migrate the perchild MPM to use the new apr signal child, and
4702 APR thread functions. [Ryan Bloom]
4704 *) Close one copy of the CGI's stdout before creating the new process.
4705 The CGI will still have stdout, because we have already dup'ed it.
4706 This keeps Apache from waiting forever to send the results of a CGI
4707 process that has forked a long-lived child process.
4708 [Taketo Kabe <kabe sra-tohoku.co.jp>]
4710 *) Remove the rest of the pthreads functions from the threaded MPM.
4711 This requires the APR support for a signal thread that was just
4714 *) Make mod_dir use a fixup for sending a redirect to the browser.
4715 Before this, we were using a handler, which doesn't make much
4716 sense, because the handler wasn't generating any data, it would
4717 either return a redirect error code, or DECLINED. This fits the
4718 current hooks better. [Ryan Morgan <rmorgan covalent.net>]
4720 *) Make the threaded MPM use APR threads instead of pthreads.
4723 *) Get mod_tls to the point where it actually appears to work in all cases.
4726 *) implement --enable-modules and --enable-mods-shared for "all" and
4727 "most". [Greg Stein]
4729 *) Move the threaded MPM to use APR locks instead of pthread locks.
4732 *) Rename mpmt_pthread to threaded. This is more in line with the
4733 fact that mpmt_pthread shouldn't be using pthreads directly, and
4734 it is a smaller name that doesn't tie into anything.
4737 *) Rename the module structures so that the exported symbol matches
4738 the file name, and it is easier to automate the installation
4739 process (generating LoadModule directives from the module filenames).
4742 *) Remove the coalesce filter. With the ap_f* functions, this filter
4743 is no longer needed. [Ryan Bloom]
4745 Changes with Apache 2.0.11
4747 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
4748 added feature of allowing a uid/gid per child process. If no
4749 uid/gid is specified, then Perchild behaves exactly like dexter.
4752 *) Get perchild building again. [Ryan Bloom]
4754 *) Don't disable threads just because we are using the prefork MPM.
4755 If somebody wants to compile without threads, they must now add
4756 --disable-threads to the configure command line. [Ryan Bloom]
4758 *) Begin to move the calls to update_child_status into common code, so
4759 that each individual MPM does not need to update the scoreboard itself.
4762 *) Allow mod_tls to compile under Unix boxes where openssl has been
4763 installed to the system include files.
4764 [Gomez Henri <new-httpd slib.fr>]
4766 *) Cleanup the mod_tls configure process. This should remove any need
4767 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
4768 configure doesn't check that yet. [Ryan Bloom]
4770 *) Add a very early prototype of SSL support (in mod_tls.c). It is
4771 vital that you read modules/tls/README before attempting to build
4774 *) Fix a potential seg fault on all platforms. David Reid fixed this
4775 on BEOS, but the problem could happen anywhere, so we don't want
4776 to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>]
4778 *) Add new LogFormat directive, %D, to log time it takes to serve a
4779 request in microseconds. [Bill Stoddard]
4781 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
4782 SetOutputFilter. This corresponds nicely with the other Set
4783 directives, which operate on containers while the Add* directives
4784 tend to work directly on extensions. [Ryan Bloom]
4786 *) Cleanup the header handling a bit. This uses the apr_brigade_*
4787 functions for the buffering so that we don't need to compute
4788 the length of the headers before we actually create the header
4789 buffer. [Ryan Bloom]
4791 *) Allow filters to buffer data using the ap_f* functions. These have
4792 become macros that resolve directly to apr_brigade_*.
4795 *) Get the Unix MPM's to do a graceful restart again. If we are going
4796 to register a cleanup with ap_cleanup_scoreboard, then we have to
4797 kill the cleanup with the same function, and that function can't be
4798 static. [Ryan Bloom]
4800 *) Install all required header files. Without these, it was not
4801 possible to compile some modules outside of the server.
4804 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
4805 forward from 1.3 to 2.0, we missed a single line, which broke regex
4806 aliases. [Ryan Bloom]
4808 *) We have a poor abstraction in the protocol. This is a temporary
4809 hack to fix the bug, but it will need to be fixed for real. If
4810 we find an error while sending out a custom error response, we back
4811 up to the first non-OK request and send the data. Then, when we send
4812 the EOS from finalize_request_protocol, we go to the last request,
4813 to ensure that we aren't sending an EOS to a request that has already
4814 received one. Because the data is sent on a different request than
4815 the EOS, the error text never gets sent down the filter stack. This
4816 fixes the problem by finding the last request, and sending the data
4817 with that request. [Ryan Bloom]
4819 *) Make the server status page show the correct restart time, and
4820 thus the proper uptime. [Ryan Bloom]
4822 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
4823 should reduce the amount of duplicate code that is required to
4824 create CGI processes.
4825 [Paul J. Reder <rederpj raleigh.ibm.com>]
4827 *) ap_new_connection() closes the socket and returns NULL if a socket
4828 call fails. Usually this is due to a connection which has been
4829 reset. [Jeff Trawick]
4831 *) Move the Apache version information out of httpd.h and into release.h.
4832 This is in preparation for the first tag with the new tag and release
4833 system. [Ryan Bloom]
4835 *) Begin restructuring scoreboard code to enable adding back in
4836 the ability to use IPC other than shared memory.
4837 Get mod_status working on Windows again. [Bill Stoddard]
4839 *) Make mod_status work with 2.0. This will work for prefork,
4840 mpmt_pthread, and dexter. [Ryan Bloom]
4842 *) Correct a typo in httpd.conf.
4843 [Kunihiro Tanaka <tanaka apache.or.jp>] PR#7154
4845 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
4847 *) Get the correct IP address if ServerName isn't set and we can't
4848 find a fully-qualified domain name at startup.
4849 PR#7170 [Danek Duvall <dduvall eng.sun.com>]
4851 *) Make mod_cgid work with SuExec. [Ryan Bloom]
4853 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
4854 'extra' stat's for user/group since they should never occur, and now
4855 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
4856 volumes. [William Rowe]
4858 *) Adopt apr features to simplify mod_includes. This changes the
4859 behavior of the USER_NAME variable, unknown uid's are now reported
4860 as USER_NAME="<unknown>" rather than the old user#000 result.
4861 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
4863 *) Adopt apr features for simplifing mod_userdir, and accept the new
4864 Win32/OS2 exceptions without hiccuping. [William Rowe]
4866 *) Replace configure --with-optim option by using and saving the
4867 environment variable OPTIM instead. This is needed because configure
4868 options do not support multiple flags separated by spaces.
4871 *) Fix some byterange handling. If we get a byte range that looks like
4872 "-999999" where that is past the end of the file, we should return
4873 a PARTIAL CONTENT status code, and return the whole file as one big
4874 byterange. This matches the 1.3 handling now. [Ryan Bloom]
4876 *) Make the error bucket a real meta-data bucket. This means that the
4877 bucket length is 0, and a read returns NULL data. If one of these
4878 buckets is passed down after the headers are sent, this data will
4879 just be ignored. [Greg Stein]
4881 *) The prefork MPM wasn't killing child processes correctly if a restart
4882 signal was received while the process was serving a request. The child
4883 process would become the equivalent of a second parent process. If
4884 we break out of the accept loop, then we need to do die after cleaning
4885 up after ourselves. [Ryan Bloom]
4887 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
4888 restarts. [Ryan Bloom]
4890 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
4891 the most optimal APR_FINFO_wanted bits. This spares Win32 from
4892 performing very expensive owner, group and permission lookups
4893 and allows the server to function until these apr_finfo_t fields
4894 are implemented under Win32. [William Rowe]
4896 *) Support for typedsafe optional functions - that is functions exported by
4897 optional modules, which, therefore, may or may not be present, depending
4898 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
4899 for sample code. [Ben Laurie]
4901 *) filters can now report an HTTP error to the server. This is done
4902 by sending a brigade where the first bucket is an error_bucket.
4903 This bucket is a simple bucket that stores an HTTP error and
4904 a string. Currently the string is not used, but it may be needed
4905 to output an error log. The http_header_filter will find this
4906 bucket, and output the error text, and then return
4907 AP_FILTER_ERROR, which informs the server that the error web page
4908 has already been sent. [Ryan Bloom]
4910 *) If we get an error, then we should remove all filters except for
4911 those critical to serving a web page. This fixes a bug, where
4912 error pages were going through the byterange filter, even though
4913 that made no sense. [Ryan Bloom]
4915 *) Relax the syntax checking of Host: headers in order to support
4916 iDNS. PR#6635 [Tony Finch]
4918 *) Cleanup the byterange filter to use the apr_brigade_partition
4919 and apr_bucket_copy functions. This removes a lot of very messy
4920 code, and hopefully makes this filter more stable.
4923 *) Remove AddModule and ClearModuleList directives. Both of these
4924 directives were used to ensure that modules could be enabled
4925 in the correct order. That requirement is now gone, because
4926 we use hooks to ensure that modules are in the correct order.
4929 *) When SuExec is specified, we need to add it to the list of
4930 targets to be built. If we don't, then any changes to the
4931 configuration won't affect SuExec, unless 'make suexec' is
4932 specifically run. [Ryan Bloom]
4934 *) Cleaned out open_file from mod_file_cache, as apr now accepts
4935 the APR_XTHREAD argument to open a file for consumption by
4936 parallel threads on win32. [William Rowe]
4938 *) Correct a bug in determining when we follow symlinks. The code
4939 expected a stat -1 result, not an apr_status_t positive error.
4940 Also check if the APR_FINFO_USER fields are valid before we
4941 follow the link. [William Rowe]
4943 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
4944 mpm_common.c. These functions are only valid on some platforms,
4945 so they should not be in the main-line code. [Ryan Bloom]
4947 *) Remove ap_chdir_file(). This function is not thread-safe,
4948 and nobody is currently using it. [Ryan Bloom]
4950 *) Do not try to run make depend if there are no .c files in the
4951 current directory, doing so makes `make depend` fail.
4954 *) Update highperformance.conf to work with either prefork or
4955 pthreads mpms. [Greg Ames]
4957 *) Stop checking to see if this is a pipelined request if we know
4958 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
4959 This keeps us from making an extra read call when serving a 1.0
4960 request. [Ryan Bloom and Greg Stein]
4962 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
4963 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
4964 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
4966 *) Fix the RFC number mentioned when complaining about a missing
4967 Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>]
4969 *) Fix an endless loop in ab which occurred when ab was posting
4970 and the server dropped the connection unexpectedly.
4973 *) Fix a segfault while handling request bodies in ap_http_filter().
4974 This problem has been seen with mod_dav usage as well as with
4975 requests where the body was just being discarded. [Jeff Trawick]
4977 *) Some adjustment on the handling and automatic setting (via
4978 hints.m4) of various compilation flags (eg: CFLAGS). Also,
4979 add the capability to specify flags (NOTEST_CFLAGS and
4980 NOTEST_LDFLAGS) which are used to compile Apache, but
4981 not used during the configuration process. Useful for
4982 flags like "-Werror". [Jim Jagielski]
4984 *) Stop using environment variables to force debug mode or
4985 no detach. We now use the -D command line argument to
4986 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
4987 [Greg Stein, Ryan Bloom]
4989 *) Change handlers to use hooks. [Ben Laurie]
4991 *) Stop returning copies of filenames from both apr_file_t and
4992 apr_dir_t. We pstrdup the filenames that we store in the
4993 actual structures, so we don't need to pstrdup the strings again.
4996 *) mod_cgi: Fix some problems where the wrong error value was being
4997 traced. [Jeff Trawick]
4999 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
5002 *) Add generic hooks. [Ben Laurie]
5004 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
5006 *) Fix a segfault caused by mod_ext_filter when the external filter
5007 program does not exist. [Jeff Trawick]
5009 *) Fix an output truncation error when on an HTTP >= 1.0 request an
5010 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
5011 was served through mod_charset_lite (or anything else that would
5012 create a transient bucket in this size range). ap_bucket_make_heap()
5013 silently failed (fixed), transient_setaside() discovered it, but
5014 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
5016 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
5017 is that some browsers send extra lines at the end of POST requests, and
5018 we don't want to delay sending data back to the user just because the
5019 browser isn't well behaved. [Ryan Bloom]
5021 *) Get SuEXEC working again. We can't send absolute paths to suExec
5022 because it refuses to execute those programs. SuEXEC also wasn't
5023 always recognizing configuration changes made using the autoconf
5026 *) Allow the buildconf process to find the config.m4 files in the correct
5027 order. Basically, we can now name config.m4 files as config\d\d.m4,
5028 and we will sort them correctly when inserting them into the build
5029 process. [Ryan Bloom]
5031 *) Get mod_cgid to use apr calls for creating the actual CGI process.
5032 This also allows mod_cgid to use ap_os_create_priviledged_process,
5033 thus allowing for SuExec execution from mod_cgid. Currently, we do
5034 not support everything that standard SuExec supports, but at least
5035 it works minimally now. [Ryan Bloom]
5037 *) Allow SuExec to be configured from the ./configure command line.
5040 *) Update some of the docs in README and INSTALL to reflect some of
5041 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>]
5043 *) If we get EAGAIN returned from the call to apr_sendfile, then we
5044 need to call sendfile again. This gets us serving large files
5045 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
5047 *) Get the support programs building cleanly again.
5048 [Cliff Woolley <cliffwoolley yahoo.com>]
5050 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
5051 current directory logic now backs up over bin/ to determine the
5052 server root from the Apache.exe path.
5054 *) Apache/Win32 now follows the standard conventions of mod_foo.so
5055 loadable modules, dynamic libs are all named libfoo.dll, and the
5056 makefile.win populates the include, lib and libexec directories.
5058 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
5059 Apache gets IPv6 listening sockets by default. Additionally, the
5060 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
5061 numeric address strings (e.g., "Listen [fe80::1]:8080").
5064 *) Modify the install directory layout. Modules are now installed in
5065 modules/. Shared libraries should be installed in libraries/, but
5066 we don't have any of those on Unix yet. All install directories
5067 are modifyable at configure time. [Ryan Bloom]
5069 *) Install all header files in the same directory on Unix. [Ryan Bloom]
5071 *) Get the functions in server/linked into the server, regardless of
5072 which modules linked into the server. This uses the same hack
5073 for Apache that we use for APR and apr-util to ensure all of the
5074 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
5075 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
5076 the scripts a bit easier.
5079 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
5080 on the query, and remove IPv4 dependencies. [Jeff Trawick]
5082 *) Get all of the auth modules to the point that they will install and
5083 be loadable into the server. Our new build/install mechanism expects
5084 that all modules will have a common name format. The auth modules
5085 didn't use that format, so we didn't install them properly.
5088 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
5089 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
5091 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
5093 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
5094 after the end of the response. [Ryan Bloom]
5096 *) Get byterange requests working with responses that do not have a
5097 content-length. Because of the way byterange requests work, we have to
5098 have all of the data before we can actually do the byterange, so we
5099 can compute the content-length in the byterange filter.
5102 *) Get exe CGI's working again on Windows.
5105 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
5106 they keep track of whether or not their post config hook has been
5107 called before. Instead of a static variable (which is replaced when
5108 the DSO is loaded a second time), use userdata in the process pool.
5111 Changes with Apache 2.0a9
5113 *) Win32 now requires perl to complete the final install step for users
5114 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
5115 and installs the conf, htdocs and htdocs/manual directories.
5118 *) Make mod_include use a hash table to associate directive tags with
5119 functions. This allows modules to implement their own SSI tags easily.
5120 The idea is simple enough, a module can insert it's own tag and function
5121 combination into a hash table provided by mod_include. While mod_include
5122 parses an SSI file, when it encounters a tag in the file, it does a
5123 hash lookup to find the function that implements that tag, and passes
5124 all of the relevant data to the function. That function is then
5125 responsible for processing the tag and handing the remaining data back
5126 to mod_include for further processing.
5127 [Paul J. Reder <rederpj raleigh.ibm.com>]
5129 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
5130 fewer parameters: the local and remote socket addresses were removed
5131 from the parameter list because all required information is available
5132 via the APR socket. [Jeff Trawick]
5134 *) Distribution directory structure reorganized to reflect a
5135 normal source distribution with external install targets.
5138 *) The MPMs that need multiple segments of shared memory now create
5139 two apr_shmem_t variables, one for each shared memory allocation.
5140 the problem is that we can't determine how much memory will be required
5141 for shared memory allocations once we try to allocate more than one
5142 variable. The MM code automatically aligns the shared memory allocations,
5143 so we end up needing to pad the amount of shared memory we want based
5144 on how many variables will be allocated out of the shared memory segment.
5145 It is just easier to create a second apr_shmem_t variable, and two
5146 shmem memory blocks.
5149 *) Cleanup the export list a bit. This creates a single unified list of
5150 functions exported by APR. The export list is generated at configure
5151 time, and that list is then used to generate the exports.c file.
5152 Because of the way the export list is generated, we only export those
5153 functions that are valid on the platform we are building on.
5156 *) Enable logging the cookie with mod_log_config
5157 [Sander van Zoest <sander covalent.net>]
5159 *) Fix a segfault in mod_info when it reaches the end of the configuration.
5162 *) Added lib/aputil/ as a placeholder for utility functions which are not
5163 specific to the Apache HTTP Server (but do not make sense with APR).
5164 The first utility is "apu_dbm": a set of functions to work with DBM
5165 files. This first version can be compiled for SDBM or GDBM databases.
5168 *) Complete re-write of mod_include. This makes mod_include a filter that
5169 uses buckets directly. This has now served the FAQ correctly.
5170 [Paul Reder <rederpj raleigh.ibm.com>]
5172 *) Allow modules to specify the first filter in a sub_request when
5173 making the sub_request. This keeps modules from having to change the
5174 output_filter immediately after creating the sub-request, and therefore
5175 skip the sub_req_output_filter. [Ryan Bloom]
5177 *) Update ab to accept URLs with IPv6 literal address strings (in the
5178 format described in RFC 2732), and to build Host header fields in
5179 the same format. This allows IPv6 literal address strings to be
5180 used with ab. This support has been tested against Apache 1.3 with
5181 the KAME patch, but Apache 2.0 does not yet work with this format
5182 of the Host header field. [Jeff Trawick]
5184 *) Accomodate an out-of-space condition in the piped logs and the
5185 rotatelogs.c code, and no longer churn log processes for this
5186 condition. [Victor J. Orlikowski]
5188 *) Add support for partial writes with apr_sendfile() to core_output_filter.
5191 Changes with Apache 2.0a8
5193 *) Add a directive to mod_mime so that filters can be associated with
5197 *) Get multi-views working again. We were setting the path_info
5198 field incorrectly if we couldn't find the specified file.
5201 *) Fix 304 processing. The core should never try to send the headers
5202 down the filter stack. Always, just setup the table in the request
5203 record, and let the header filter convert it to data that is ready
5207 *) More fixes for the proxy. There are still bugs in the proxy code,
5208 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
5212 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
5215 *) APR: Add new apr_getopt_long function to handle long options.
5216 [B. W. Fitzpatrick <fitz red-bean.com>]
5218 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
5219 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
5220 hostname resolution/address string parsing and building
5221 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
5222 of one of the apr_sockaddr_t structures for a socket. Change
5223 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
5225 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
5226 I have proxied pages with it, cleanup will commence soon.
5229 *) Make the proxy work with filters. This isn't perfect, because we
5230 aren't dealing with the headers properly. [Ryan Bloom]
5232 *) Do not send a content-length iff the C-L is 0 and this is a head
5233 request. [Ryan Bloom]
5235 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
5236 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
5238 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
5240 *) Get the default_handler to stop trying to deal with HEAD requests.
5241 The idea is to let the content-length filter compute the C-L before
5242 we try to send the data. If we can get the C-L correctly, then we
5243 should send it in the HEAD response.
5246 *) The Header filter can now determine if a body should be sent based
5247 on r->header_only. The general idea of this is that if we delay
5248 deciding to send the body, then we might be able to compute the
5249 content-length correctly, which will help caching proxies to cache
5250 our data better. Any handler that doesn't want to try to compute
5251 the content-length can just send an EOS bucket without data and
5252 everything will just work.
5255 *) Add the referer to the error log if one is available.
5256 [Markus Gyger <mgyger itr.ch>]
5258 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
5259 change, the root of the configuration tree has been exposed to modules
5261 [Ryan Morgan <rmorgan covalent.net>]
5263 *) Get the core_output_filter to use the bucket interface directly.
5264 This keeps us from calling the content-length filter multiple times
5265 for a simple static request.
5268 *) We are sending the content-type correctly now.
5269 [Ryan Bloom and Will Rowe]
5271 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
5272 a bogus bytes-sent value when the only thing being sent was trailers
5273 and writev() returned an error (or EAGAIN). [Jeff Trawick]
5275 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
5276 hints file to determine which platforms define
5277 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
5280 *) APR: add apr_get_home_directory() [Jeff Trawick]
5282 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
5284 *) Not all platforms have INADDR_NONE defined by default. Apache
5285 used to make this check and define INADDR_NONE if appropriate,
5286 but APR needs the check too, and I suspect other applications will
5287 as well. APR now defines APR_INADDR_NONE, which is always a valid
5288 value on all platforms.
5289 [Branko Èibej <brane xbc.nu>]
5291 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
5292 [Shuichi Kitaguchi <ki hh.iij4u.or.jp>]
5294 *) Relax the syntax checking of Host: headers in order to support
5295 iDNS. PR#6635 [Tony Finch]
5297 *) When reading from file buckets we convert to an MMAP if it makes
5298 sense. This also simplifies the default handler because the
5299 default handler no longer needs to try to create MMAPs.
5302 *) BUFF has been removed from the main server. The BUFF code will remain
5303 in the code until it has been purged from the proxy module as well.
5306 *) Byteranges have been completely re-written to be a filter. This
5307 has been tested, and I believe it is working correctly, but it could
5308 doesn't work for the Adobe Acrobat plug-in. The output almost matches
5309 the output from 1.3, the only difference being that 1.3 includes
5310 a content-length in the response, and this does not.
5313 *) APR read/write functions and bucket read functions now operate
5314 on unsigned integers, instead of signed ones. It doesn't make
5315 any sense to use signed ints, because we return the error codes,
5316 so if we have an error we should report 0 bytes read or written.
5319 *) Always compute the content length, whether it is sent or not.
5320 The reason for this, is that it allows us to correctly report
5321 the bytes_sent when logging the request. This also simplifies
5322 content-length filter a bit, and fixes the actual byte-reporing
5323 code in mod_log_config.c
5326 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
5327 it says, because it was only used by EOS and FLUSH buckets. Since
5328 neither of those are required at the end of a brigade, this was
5329 really signifying FLUSH_THE_DATA, but that can be determined better
5330 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
5331 buckets now return a length of 0, which is actually the amount of data
5332 read, so they make more sense.
5335 *) Allow the core_output_filter to save some data past the end of a
5336 request. If we get an EOS bucket, we only send the data if it
5337 makes sense to send it. This allows us to pipeline request
5338 responses. As a part of this, we also need to allocate mmap
5339 buckets out of the connection pool, not the request pool. This
5340 allows the mmap to outlive the request.
5343 *) Make blocking and non-blocking bucket reads work correctly for
5344 sockets and pipes. These are the only bucket types that should
5345 have non-blocking reads, because the other bucket types should
5346 ALWAYS be able to return something immediately.
5349 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
5350 server, but use Ctrl+Break to initiate a graceful restart
5351 instead of duplicating behavior. [John Sterling]
5353 *) Patch mod_autoindex to set the Last-Modified header based on
5354 the directory's mtime, and add the ETag header. [William Rowe]
5356 *) Merge the 1.3 patch to add support for logging query string in
5357 such a way that "%m %U%q %H" is the same as "%r".
5360 *) Port three log methods from mod_log_config 1.3 to 2.0:
5361 CLF compliant '-' byte count, method and protocol.
5364 *) Add a new LogFormat directive, %c, that will log connection
5365 status at the end of the response as follows:
5366 'X' - connection aborted before the response completed.
5367 '+' - connection may be kept-alive by the server.
5368 '-' - connection will be closed by the server.
5371 *) Expand APR for WinNT to fully accept and return utf-8 encoded
5372 Unicode file names and paths for Win32, and tag the Content-Type
5373 from mod_autoindex to reflect that charset if the feature
5374 macro APR_HAS_UNICODE_FS is true. [William Rowe]
5376 *) Compute the content length (and add appropriate header field) for
5377 the response when no content length is available and we can't use
5378 chunked encoding. [Jeff Trawick]
5380 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
5381 so that content input filters get dechunked data when using
5382 the default handler. Also removed REQUEST_CHUNKED_PASS.
5385 *) Add mod_ext_filter as an experimental module. This module allows
5386 the administrator to use external programs as filters. Currently,
5387 only filtering of output is supported. [Jeff Trawick]
5389 *) Most Apache functions work on EBCDIC machines again, as protocol
5390 data is now translated (again). [Jeff Trawick]
5392 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
5393 the EBCDIC support. They are noops on ASCII machines, so this
5394 type of translation doesn't have to be surrounded by #ifdef
5395 CHARSET_EBCDIC. [Jeff Trawick]
5397 *) Fix mod_include. tag commands work again, and the server will
5398 send the FAQ again. This also allows mod_include to set aside
5399 buckets that include partial buckets.
5400 [Ryan Bloom and David Reid]
5402 *) Add suexec support back. [Manoj Kasichainula]
5404 *) Lingering close now uses the socket directly instead of using
5405 BUFF. This has been tested, but since all we can tell is that it
5406 doesn't fail, this needs to be really hacked on.
5409 *) Allow filters to modify headers and have those headers be sent to
5410 the client. The idea is that we have an http_header filter that
5411 actually sends the headers to the network. This removes the need
5412 for the BUFF to send headers.
5415 *) Charset translation: mod_charset_lite handles translation of
5416 request bodies. Get rid of the xlate version of ap_md5_digest()
5417 since we don't compute digests of filtered (e.g., translated)
5418 response bodies this way anymore. (Note that we don't do it at
5419 all at the present; somebody needs to write a filter to do so.)
5422 *) Input filters and ap_get_brigade() now have a input mode parameter
5423 (blocking, non-blocking, peek) instead of a length parameter.
5426 *) Update the mime.types file to the registered media types as
5427 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>,
5430 *) Namespace protect some macros declared in ap_config.h
5433 *) Support HTTP header line folding with input filtering.
5436 *) Mod_include works again. This should still be re-written, but at
5437 least now we can serve an SHTML page again.
5440 *) Begin to remove BUFF from the core. Currently, we keep a pointer
5441 to both the BUFF and the socket in the conn_rec. Functions that
5442 want to use the BUFF can, functions that want to use the socket,
5443 can. They point to the same place.
5446 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
5447 [Tomas "Ögren" <stric ing.umu.se>]
5449 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
5450 associated pool goes away. (APR pipes on OS/2 were already had this
5451 logic.) This resolvs a fatal file descriptor leak with CGIs.
5454 *) The final line of the config file was not being read if there was
5455 no \n at the end of it. This was caused by apr_fgets returning
5456 APR_EOF even though we had read valid data. This is solved by
5457 making cfg_getline check the buff that was returned from apr_fgets.
5458 If apr_fgets return APR_EOF, but there was data in the buf, then we
5459 return the buf, otherwise we return NULL.
5462 *) Piped logs work again in the 2.0 series.
5465 *) Restore functionality broken by the mod_rewrite security fix:
5466 rewrite map lookup keys and default values are now expanded
5467 so that the lookup can depend on the requested URI etc.
5468 PR #6671 [Tony Finch]
5470 *) SECURITY: Tighten up the syntax checking of Host: headers to fix a
5471 security bug in some mass virtual hosting configurations
5472 that can allow a remote attacker to retrieve some files
5473 on the system that should be inaccessible. [Tony Finch]
5475 *) Add a pool bucket type. This bucket is used for data allocated out
5476 of a pool. If the pool is cleaned before the bucket is destroyed, then
5477 the data is converted to a heap bucket, allowing it to survive the
5481 *) Add a flush bucket. This allows modules to signal that the filters
5482 should all flush whatever data they currently have. There is no way
5483 to actually force them to do this, so if a filter ignores this bucket,
5484 that's life, but at least we can try with this.
5487 *) Add an output filter for sub-requests. This filter just strips the
5488 EOS bucket so that we don't confuse the main request's core output
5489 filter by sending multiple EOS buckets. This change also makes sub
5490 requests start to send EOS buckets when they are finished.
5493 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
5494 makes ap_bucket_destroy a return void, which is okay because it
5495 used to always return APR_SUCCESS, and nobody ever checked its
5496 return value anyway.
5497 [Cliff Woolley <cliffwoolley yahoo.com>]
5499 *) Remove the index into the bucket-type table from the buckets
5500 structure. This has now been replaced with a pointer to the
5501 bucket_type. Also add some macros to test the bucket-type.
5504 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
5505 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
5506 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
5507 All _VAR_ flavors changes to _DATA to be absolutely clear.
5510 *) Add support for /, //, //servername and //server/sharename
5511 parsing of <Directory> blocks under Win32 and OS2.
5512 [Tim Costello, William Rowe, Brian Harvard]
5514 *) Remove the function pointers from the ap_bucket type. They have been
5515 replaced with a global table. Modules are allowed to register bucket
5516 types and use then use those buckets.
5519 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
5520 once we finish writing the request body to the cgi child process;
5521 otherwise, the client doesn't hit EOF on stdin. Small request bodies
5522 worked without this change (for reasons I don't understand), but large
5523 ones didn't. [Jeff Trawick]
5525 *) Remove file bucket specific information from the ap_bucket type.
5526 This has been moved to a file_bucket specific type that hangs off
5527 the data pointer in the ap_bucket type.
5530 *) Input filtering now has a third argument. This is the amount of data
5531 to read from lower filters. This argument can be -1, 0, or a positive
5532 number. -1 means give me all the data you have, I'll deal with it and
5533 let you know if I need more. 0 means give me one line and one line
5534 only. A positive number means I want no more than this much data.
5536 Currently, only 0 and a positive number are implemented. This allows
5537 us to remove the remaining field from the conn_rec structure, which
5541 *) Big cleanup of the input filtering. The goal is that http_filter
5542 understands two conditions, headers and body. It knows where it is
5543 based on c->remaining. If c->remaining is 0, then we are in headers,
5544 and http_filter returns a line at a time. If it is not 0, then we are
5545 in body, and http_filter returns raw data, but only up to c->remaining
5546 bytes. It can return less, but never more.
5547 [Greg Ames, Ryan Bloom, Jeff Trawick]
5549 *) mod_cgi: Write all of the request body to the child, not just what
5550 the kernel would accept on the first write. [Jeff Trawick]
5552 *) Back out the change that moved the brigade from the core_output_filters
5553 ctx to the conn_rec. Since all requests over a given connection
5554 go through the same core_output_filter, the ctx pointer has the
5558 *) Fix another bug in the send_the_file() read/write loop. A partial
5559 send by apr_send would cause unsent data in the read buffer to
5560 get clobbered. Complete making send_the_file handle partial
5561 writes to the network.
5564 *) Fix a couple of type fixes to allow compilation on AIX again
5565 [Victor J. Orlikowski <v.j.orlikowski gte.net>]
5567 *) Fix bug in send_the_file() which causes offset to be ignored
5568 if there are no headers to send.
5571 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
5572 filter. Useful for supporting Windows 9* with a binary
5573 compiled on Windows NT.
5576 Changes with Apache 2.0a7
5578 *) Reimplement core_output_filter to buffer/save bucket brigades
5579 across multiple calls to the core_filter. The brigade will be
5580 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
5581 thresholds are hit or the EOS bucket is received.
5584 *) Create experimental filter (buffer_filter) that coalesces bytes
5585 into one large buffer before invoking the next filter in the
5586 chain. This filter is particularly useful with the current
5587 implementation of mod_autoindex when it inserted above the
5588 chunk_filter. mod_autoindex generates a lot of brigades that
5589 containing buckets holding just a few bytes each. The
5590 buffer_filter coalesces these buckets into a single large bucket.
5593 *) Add apr_sendfile() support into the core_output_filter.
5596 *) Add apr_sendv() support into the core_output_filter.
5599 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
5600 [Mike Abbott <mja sgi.com>]
5602 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
5603 make much sense, because Apache uses buckets instead of BUFFs now.
5606 *) send_the_file now falls back to a read/write loop on platforms that
5607 do not have sendfile.
5608 [Ryan Bloom and Brian Havard]
5610 *) Install apachectl correctly, and substitute the proper values so
5611 that it works again. [Ryan Bloom]
5613 *) Better(??) handle platforms that lack sendfile().
5616 *) APR now has UUID generation/formatting/parsing support.
5619 *) Begin the http_filter. This is an input filter that understands
5620 the absolute basic amount required to parse an HTTP Request. The
5621 goal is to be able to split headers from request body before passing
5622 the data back to the other filters.
5625 *) Bring forward from 1.3.13 the config directory implementation
5628 *) install apxs if it is created
5631 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
5632 conversions. [William Rowe]
5634 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
5635 ap_add_output_filter(). [Jeff Trawick]
5637 *) Multiple build and configuration fixes
5640 -add datadir and localstatedir substitutions
5642 -fix logfilename misspelling
5643 -fix evaluation of installation dir variables and
5644 -replace $foobar by $(foobar) to be usefull in the makefile
5648 -add rules for cross-compiling in rules.mk. Okay, rule to check for
5649 $CC_FOR_BUILD is still missing
5650 -use CHECK_TOOL instead of CHECK_PROG for ranlib
5651 -add missing "AR=@AR@" to severaly Makefile.in's
5652 -cache result for "struct rlimit"
5653 -compile all helper programs with native and cross compiler
5654 and use the native version to generate header file
5655 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5657 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
5659 ["Rüdiger" Kuhlmann <Tadu gmx.de>]
5661 *) Fix a bug where a client which only sends \n to delimit header
5662 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
5663 message. Start working on ebcdic co-existance with input
5665 [William Rowe, Greg Ames]
5667 *) If mod_so is enabled in the server always create libexec, even
5668 if there are no modules installed in this directory. This is a
5669 requirement for APXS to work correctly.
5672 *) Connection oriented output filters are now stored in the
5673 conn_rec instead of the request_rec. This allows us to add the
5674 output filter in the pre-connection phase instead of the
5675 post_read_request phase, which keeps us from trying to write an
5676 error page before we have a filter to write to the network.
5677 [Ryan Bloom, Jeff Trawick, and Greg Ames]
5679 *) Cleaning up an mmap bucket no longer deletes the mmap. An
5680 mmap can be used across multiple buckets (default_handler with
5681 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
5682 the mmap itself can't be associated with the bucket.
5685 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
5688 *) Radical surgery to improve mod_isapi support under Win32.
5689 Includes a number of newer ServerSupportFunction calls, support
5690 for ReadClient (in order to retrieve POSTs greater than 48KB),
5691 and general bug fixes to more reliably load ISAPI .dll's and
5692 prevent leaking handle resources. Note: There are still
5693 discrepancies between IIS's and Apache's ServerVariables, and
5694 async calls are still not supported. Additional warnings are
5695 logged to facilitate debugging of unsupported ISAPI calls.
5698 *) Add input filtering to Apache. The basic idea for the input
5699 filters is the same as the ideas for output filters. The biggest
5700 difference is that instead of calling ap_pass_brigade, ap_get_brigade
5701 should be called, and the order of execution for the filter itself is
5702 different. When writing an output filter, a brigade is passed in,
5703 and filters operate directly on that brigade, when done, they call
5704 ap_pass_brigade. Input filters are the exact opposite. Because input
5705 is not a push operation, filters first call ap_get_brigade. When this
5706 function returns, the input filter will be left with a valid brigade.
5707 The input filter should then operate on the brigade, and return.
5710 *) Fix building on BSD/OS using its native make. The build system
5711 falls back to the BSD .include directive on that host platform.
5714 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
5715 SHA1 and plaintext password encodings. Make feature tests a
5716 bit more flexible. [William Rowe]
5718 *) Charset translation: mod_charset_lite handles output content
5719 translation in a filter. mod_charset_lite no longer ignores
5720 subrequests. A bunch of cruft related to BUFF's support for
5721 translating request and response bodies was removed.
5724 *) Move the addition of the CORE filter to the post_read_request
5725 hook in http_core.c. This removes the need to add the filter in
5726 multiple places and allows for an SSL module to be added much
5727 simpler. [Ryan Bloom]
5729 *) SECURITY [CVE-2000-0913] (cve.mitre.org):
5730 Fix a security problem that affects certain configurations of
5731 mod_rewrite. If the result of a RewriteRule is a filename that
5732 contains expansion specifiers, especially regexp backreferences
5733 $0..$9 and %0..%9, then it may be possible for an attacker to
5734 access any file on the web server. [Tony Finch]
5736 *) Fix a bug where errors that are detected during early request parsing
5737 don't produce visible HTTP error messages at the browser, because
5738 the core_filter wasn't present. [Greg Ames]
5740 *) Provide apr_socklen_t as a portability aid.
5741 [Victor J. Orlikowski]
5743 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
5744 as well as a comment arg to the add, adduser and update cmds.
5745 update allows the user to clear or preserve pw/groups/comment.
5746 Fixed a bug in dbmmanage that prevented the check option from
5747 parsing a password followed by :group... text. Corrected the
5748 seed calcualation for Win32 systems, and added -lsdbm support.
5751 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
5754 *) Avoid a segfault when parsing .htaccess files. An
5755 uninitialized tree pointer was passed to ap_build_config().
5758 *) Change the way that inet_addr & inet_network are checked for
5759 in APR's configure process to allow BeOS BONE to correctly
5760 find them. With this change BeOS BONE now builds from source
5761 with no problems. [David Reid]
5763 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
5764 the end of the parameters to execve() was stored in the wrong
5765 location, overlaying the storage beyond the newargs[] array and
5766 also passing uninitialized storage to execve(), which would
5767 sometimes fail with EFAULT. [Jeff Trawick]
5769 *) Fix a bug parsing configuration file containers. With a sequence
5770 like this in the config file
5772 <IfModule mod_kilroy.c>
5775 <IfModule mod_lovejoy.c>
5780 the second container would be terminated at the blank line due to
5781 sediment in the buffer from reading the prior </IfModule> and an
5782 error message would be generated for the real </IfModule> for the
5783 second container. Also due to this problem, any two characters
5784 could be used for "</" in the close of a container.
5787 *) ap_add_filter prototype changed to remove the ctx pointer. The
5788 pointer still remains in the filter structure, but it can not be
5789 a part of the ap_add_filter prototype. The reason is that when
5790 the core uses AddFilter to add a filter to the stack it doesn't
5791 know how to allocate the ctx pointer, or even how much memory should
5792 be allocated. The filters will have to be responsible for allocating
5793 the ctx memory when they need it.
5796 *) Add an AddFilter directive. This directive takes a list of filters
5797 that should be activated for the requested resource.
5800 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
5801 some other platforms). [Jeff Trawick]
5803 *) Modify mod_include to be a filter. Currently, it has only been tested
5804 on actual files, but it should work for CGI scripts too.
5807 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
5808 writes. apr_flush() for Unix: handle interrupted writes.
5811 *) NameVirtualHost can now take "*" as an argument instead of
5812 an IP address. This allows you to create a purely name-based
5813 virtual hosting server that does not have any IP addresses in
5814 the configuration file and which ignores the local address
5815 of any connections. PR #5595, PR #4455 [Tony Finch]
5817 *) Fix some compile warnings in mod_mmap_static.c
5818 [Mike Abbott <mja sgi.com>]
5820 *) Fix chunking problem with CGI scripts. The general problem was that
5821 the CGI modules were adding an EOS bucket and then the core added an
5822 EOS bucket. The chunking filter finalizes the chunked response when it
5823 encounters an EOS bucket. Because two EOS buckets were sent, we
5824 finalized the response twice. The fix is to make sure we only send one
5825 EOS, by utilizing a flag in the request_rec.
5828 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
5829 and Win32. Previously, the first read from an apr_file_t set up via
5830 apr_put_os_file() would return a '\0'. [Jeff Trawick]
5832 *) Mod_cgid now creates a single element bucket brigade, with a pipe
5833 bucket, instead of using BUFF's and ap_r*.
5836 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
5837 [Mike Abbott <mja sgi.com>]
5839 *) Remove ap_bopenf from buff code. This required modifying the file_cache
5840 code to use APR file's directly instead of going through BUFFs.
5843 *) Fix compile break on some platforms for mod_mime_magic.c
5844 [John K. Sterling <sterling covalent.net>]
5846 *) Fix merging of AddDefaultCharset directive.
5847 PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>]
5849 *) Minor revamp of the rlimit sections of code. We now test
5850 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
5851 is now "available" even if the platform doesn't support
5852 the rlimit family (it's just a noop though). [Jim Jagielski]
5854 *) Migrate the pre-selection of which MPM to use for specific
5855 platforms to hints.m4, which contains (or should contain)
5856 all platform specific "hints". [Jim Jagielski]
5858 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
5861 *) Add tables with non-string/binary values to APR.
5864 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
5867 *) Update PCRE to version 3.2. [Ryan Bloom]
5869 *) Change the way buckets' destroy functions are called so that
5870 they can be more directly used when changing the type of a
5871 bucket in place. [Tony Finch]
5873 *) Add generic support for reference-counting the resources used by
5874 buckets, and alter the HEAP and MMAP buckets to use it. Change
5875 the way buckets are initialised to support changing the type of
5876 buckets in place, and use it when setting aside TRANSIENT buckets.
5877 Change the implementation of TRANSIENT buckets so that it can be
5878 mostly shared with IMMORTAL buckets, which are now implemented.
5881 Changes with Apache 2.0a6
5883 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
5885 *) Add a chunking filter to Apache. This brings us one step closer
5886 to removing BUFF. [Ryan Bloom]
5888 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
5889 added to the stack is the last filter to be called. [Ryan Bloom]
5891 *) Apache 2.0 has been completely documented using Scandoc. The
5892 docs can be generated by running 'make docs'. [Ryan Bloom]
5894 *) Add filtered I/O to Apache. This is based on bucket brigades,
5895 Currently the buckets still use BUFF under the covers, but that
5896 should change quickly. The only currently written filter is the
5897 core filter which just calls ap_bwrite. [The Apache Group]
5899 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
5900 built with thread support. [Jeff Trawick]
5902 *) Abort configuration if --with-layout was specified and there's
5903 no layout definition file. [Ken Coar]
5905 *) Add support for '--with-port=n' option to configure. [Ken Coar]
5907 *) Add support for extension methods for the Allow response header
5908 field, and an API routine for accessing r->allowed and the
5909 list of extension methods in a unified manner. [Ken Coar]
5911 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
5912 [Rob Simonson <simo us.ibm.com>]
5914 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
5915 APACHE_XLATE builds. [Jeff Trawick]
5917 *) A configuration file parsing problem was fixed. When the
5918 configuration file started with an IfModule/IfDefine container,
5919 only the last statement in the container would be retained.
5922 Changes with Apache 2.0a5
5924 *) Perchild is serving pages after passing them to different child
5925 processes. There are still a lot of bugs, but this does work. I
5926 have made requests against the same installation of Apache, and had
5927 different servers use different user IDs to serve the responses.
5928 This change moves to using socketpair instead of an AF_UNIX socket.
5931 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
5932 It can't seem to pass between child processes yet, but I think we
5933 are closer now than before. This moves us back to using Unix
5934 Domain Sockets. [Ryan Bloom]
5936 *) libapr functions and types renamed with apr_ prefix.
5937 #include "apr_compat.h" for 1.3.x backwards compat
5940 *) Fix problems with APR sockaddr handling on Win32. It didn't always
5941 return the right information on the local socket address.
5942 [Gregory Nicholls <gnicholls level8.com>]
5944 *) ap_recv() on Win32: Set bytes-read to 0 on error.
5945 [Gregory Nicholls <gnicholls level8.com>]
5947 *) Add an option to not detach from the controlling terminal without
5948 going into single process mode. This allows for much easier
5949 debugging of the process startup code. [Ryan Bloom]
5951 *) ab: don't use perror() to report the failure of an APR function.
5954 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
5955 scoreboard on graceful restarts.
5958 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
5959 An invalid ap_proc_t was passed to ap_create_process().
5962 *) Allow modules to register filters. Those filters are still
5963 never called, but this is a step in the right direction.
5964 [Ryan Bloom and Greg Stein]
5966 *) Register the mod_cgid daemon process for cleanup so that it is
5967 killed at termination if it does not die when the parent gets
5968 SIGTERM. This change is to fix occasional problems where the
5969 process stays around. Bugs in similar logic in mod_rewrite and
5970 mod_include were also fixed. [Jeff Trawick]
5972 *) Fix a bug in the time handling. Basically, we were imploding a time
5973 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
5974 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
5975 uses those two fields to adjust the time value. Because of the HTTP
5976 spec, both of those values can be zero'ed out safely. This fixes
5977 the bug correctly. [Ryan Bloom]
5979 *) Fix a couple of place in the Windows code where the wrong error
5980 code was being returned. [Gregory Nicholls <gnicholls level8.com>]
5982 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
5984 *) Added the APR_EOL_STR macro for platform dependent differences in
5985 logfiles and other raw text (such as all APR files). Fixes logfiles
5986 not terminated with cr/lf sequences in Win32. [William Rowe]
5988 *) Move all strings functions in APR to src/lib/apr/strings and create
5989 apr_strings.h for the prototypes. [Ryan Bloom]
5991 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
5992 to repeat the syscall until we stop getting EINTR. I noticed a
5993 related problem at termination (SIGTERM) on FreeBSD when using
5994 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
5995 implementation work properly with child init. Previously, ap_lock()
5996 was essentially a no-op because all children were using different
5997 locks and thus nobody ever blocked. [Jeff Trawick]
5999 *) The htdocs/ tree has been moved out of the CVS source tree into
6000 a separate area for easier development. This has NO EFFECT on
6001 end-users or Apache installations. [Ken Coar]
6003 *) Integrate the mod_dav module for WebDAV protocol handling. This
6004 adds the dav and dav_fs modules, the SDBM library, and additional
6005 XML handling utilities. [Greg Stein]
6007 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
6010 *) Update the lib/expat-lite/ library (bring forward changes from
6011 the Apache 1.3 repository). [Greg Stein]
6013 *) If sizeof(long long) == sizeof(long), then prefer long in APR
6014 configure.in. [Dave Hill <ddhill zk3.dec.com>]
6016 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
6017 machines where sendfile is detected, but nobody has written ap_sendfile.
6018 [Dave Hill <ddhill zk3.dec.com>]
6020 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
6022 *) ab would start up more connections than needed, then quit when the
6023 desired number were finished. Also fixed a logic error involving
6024 ab keepalives. [Victor J. Orlikowski]
6026 *) WinNT: Implement non-blocking pipes with timeouts to communicate
6027 with CGIs. Apache 2.0a4 had non-blocking pipes but without
6028 timeouts (i.e, if a timeout was specified, the pipe reverted to
6029 a full blocking pipe). Now the behaviour is more in line with
6030 Unix non-blocking pipes.
6033 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
6034 cache open file handles along with accept socket reuse enables
6035 Apache 2.0 to serve non-keepalive requests for static files at
6036 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
6037 and Apache 2.0 will serve almost 1200 rps on my system).
6040 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
6041 supports two config directives, mmapfile (same behavious as
6042 mod_mmap_static) and cachefile. Use the cachefile directive
6043 to cache open file handles. This directive only works on systems
6044 that have implemented the ap_sendfile API. cachefile works today
6045 on Windows NT, but has not been tested on any flavors of Unix.
6048 *) Cleanup the configuration. With the last few changes the
6049 configuration process automatically:
6050 inherits information about how to build from APR. Allowing
6051 APR to inform Apache that it should or should not use -ldl
6053 Detects which mod_cgi should be used mod_cgi or mod_cgid,
6054 based on the threading model
6056 Apache calls APR's configure process before finishing it's
6057 configuration processing, allowing for more information flow
6062 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
6063 with non-zero argument makes the socket non-blocking. BeOS and
6064 OS/2 already worked this way. [Jeff Trawick]
6066 *) ap_close() now calls ap_flush() for buffered files, so write
6067 operations work a whole lot better on buffered files.
6070 *) Fix error messages issued from MPMs which explain where to change
6071 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
6074 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
6075 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
6076 now the way that the blocking state of a pipe is manipulated.
6077 ap_block_pipe() is gone. [Jeff Trawick]
6079 *) Correct the problem where the only local host name that the IP stack
6080 can discover are 'undotted' private names. If no fully qualified
6081 domain name can be identified, the default ServerName will be set to
6082 the machine's IP address string. A warning is always provided if the
6083 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
6085 *) Repair problems with config file processing which caused segfault
6086 at init when virtual hosts were defined and which caused ServerName to
6087 be ignored when there was no valid DNS setup. [Jeff Trawick]
6089 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
6091 *) Add ap_sendfile implementation for AIX
6092 [Victor J. Orlikowski]
6094 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
6095 apr_network_io.h, and apr_thread_proc.h.
6096 [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick]
6098 *) Bring the allocation and pool debugging code back into a working
6099 state. This will need to be tested as so far it's only been used on
6102 *) Change configuration command setup to be properly typesafe when in
6103 maintainer mode. Note that this requires a compiler that can initialise
6104 unions. [Ben Laurie]
6106 *) Turn on buffering for config file reads. Part of this was to
6107 repair buffered I/O support in Unix and implement buffered
6108 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
6110 *) Win32: Fix problem where UTC offset was not being set correctly
6111 in the access log. Problem reported on news group by Jerry Baker.
6114 *) Fix segfault when reporting this type of syntax error:
6115 "</container> without matching <container> section", where
6116 container is VirtualHost or Directory or whatever.
6119 *) SECURITY [CAN-2000-1204] (cve.mitre.org):
6120 Prevent the source code for CGIs from being revealed when
6121 using mod_vhost_alias and the CGI directory is under the document root
6122 and a user makes a request like http://www.example.com//cgi-bin/cgi
6123 as reported in <news:960999105.344321 ernani.logica.co.uk>
6126 *) Add support for the new Beos NetwOrking Environment (BONE)
6129 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
6130 final input char is incomplete; ap_bwrite_xlate() now handles
6131 incomplete final input chars. [Jeff Trawick]
6133 *) Yet another update to saferead/halfduplex stuff -- need to ensure
6134 that a bhalfduplex call occurs before logging or else DNS and
6135 such can delay the last packet of the response. [Dean Gaudet]
6137 *) Some syscall reduction in APR on unix -- don't seek when setting
6138 up an mmap; and don't fcntl() more than once per socket.
6141 *) When mod_cgid is started as root, the cgi daemon now switches
6142 to the configured User/Group (like other httpd processes)
6143 instead of continuing as root. [Jeff Trawick]
6145 *) The prefork MPM now uses an APR lock for the accept() mutex.
6146 It has not been getting a lock at all recently. httpd -V now
6147 displays APR's selection of the lock mechanism instead of the
6148 symbols previously respected by prefork. [Jeff Trawick]
6150 *) Change the mmap() feature test to check only for existence.
6151 The previous check required features not used by Apache.
6154 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
6155 sometimes mangled. The len parm to accept() was not
6156 initialized, leading sometimes to an endless loop of failed
6157 accept() calls on OS/390 and anywhere else that failed the call
6158 if the len was negative. Use <sys/un.h> for struct sockaddr_un
6159 instead of declaring it ourselves to fix a compilation problem
6160 on Solaris. [Jeff Trawick]
6162 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
6164 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
6166 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
6168 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
6169 initialization if ALLOC_DEBUG is defined; no known symptom
6170 otherwise. [Jeff Trawick]
6172 *) Fix typo in configure script when checking for mod_so. bash
6173 doesn't seem to have a problem but /bin/sh on Solaris does.
6174 Symptom: "./configure: test: unknown operator =="
6177 *) Rebind the Win32 NT and 9x services control into the MPM.
6178 All console, WinNT SCM and Win9x pseudo-service control code is
6179 now wrapped within the WinNT MPM.
6182 *) Make a copy of getenv("PATH") before storing for later use. Some
6183 getenv() implementations use the same storage for successive calls.
6184 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
6186 *) Server Tokens work in 2.0 again. This also propogates the change
6187 to allow just the product name in the server string using
6191 Changes with Apache 2.0a4
6193 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
6194 won't need to call it. [Greg Ames, Jeff Trawick]
6196 *) Move pre_config hook call to between configuration read and config
6197 tree walk. This allows all modules to implement pre_config hooks
6198 and know that they will be called at an appropriate time.
6201 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
6204 *) Add pre-config hooks back to all modules.
6207 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
6208 ContentDigest enabled and we can't/don't mmap the file.
6211 *) We now report the correct line number for syntax errors in config
6212 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
6214 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
6215 related bugs, and changed shmem/locking to use apr API. Shared-mem
6216 is currently disabled, however, because of problems with graceful
6217 restarts. [Ronald Tschalär]
6219 *) Fix corruption of IFS variable in --with-module= handling.
6220 Depending on the user's shell or customization thereof, there
6221 would be errors generating ap_config_auto.h later in the configure
6222 procedure. [Jeff Trawick]
6224 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
6225 isn't used (as in 1.3), except that on Unix it is now logged via
6226 ap_log_rerror() instead of by the child having STDERR_FILENO refer
6227 to the error log. [Greg Ames, Jeff Trawick]
6229 *) Add '-D' argument processing for run time configuration defines.
6232 *) Organize http_main.c as independent code, such that no code or
6233 global data is exported from it. WIN32 will dynamically link it
6234 to the server core, so this will prevent mutual dependency.
6237 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
6238 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
6241 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
6242 [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>]
6244 *) Add mod_charset_lite for configuring character set translation.
6247 *) Add '-n' option to htpasswd to make it print its user:pw record
6248 on stdout rather than having to frob a text file. [Ken Coar]
6250 *) Fix saferead. Basically, we flush the output buffer if a read on the
6254 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
6255 a conversion is single-byte only. [Jeff Trawick]
6257 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
6258 the BeOS 5.0 documentation says that shutdown doesn't work yet.
6261 *) Fix some minor errors where pid was being manipulated as an int
6262 instead of the portable pid_t. [Roy Fielding]
6264 *) Fix some error log prints that were printing the pointer to a
6265 structure rather than the pid within the structure.
6266 [Jeff Trawick, Roy Fielding]
6268 *) ab: Fix a command-line processing bug; track bad headers in
6269 err_response; support reading headers up to 2K.
6270 [Ask Bjoern Hansen <ask valueclick.com>]
6272 *) Fix ap_resolve_env() so that it handles new function added in a prior
6273 alpha (see "Added the capability to do ${ENVVAR} constructs in the
6274 config file.") as well as the constructs used by mod_rewrite.
6275 [Paul Reder <rederpj raleigh.ibm.com>]
6277 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
6279 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
6280 APR to perform translation, instead of accessing the hard-coded tables
6281 in 1.3's ebcdic.c. [Jeff Trawick]
6283 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
6286 *) Add the ability to hook into the config file reading phase. Basically
6287 if a directive is specified EXEC_ON_READ, then when that directive is
6288 read from the config file, the assocaited function is executed. This
6289 should only be used for those directives that must muck with HOW the
6290 server INTERPRETS the config. This should not be used for directives
6291 that re-order or replace items in the config tree. Those changes should
6292 be made in the pre-config step.
6295 *) Add mod_example to the build system.
6298 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
6299 byte character sets. [Jeff Trawick]
6301 *) Pick up various EBCDIC fixes from 1.3 (from Martin
6302 Kraemer and Oliver Reh originally according to the change log).
6305 *) Fix a couple of problems in RFC1413 support (controlled by the
6306 IdentityCheck directive). Apache did not build the request string
6307 properly and more importantly Apache would loop forever if the
6308 would-be ident server dropped the connection before sending a
6309 properly terminated response. [Jeff Trawick]
6311 *) apxs works in 2.0.
6314 *) Reliable piped logs work in 2.0.
6317 *) Introduce a hash table implementation into APR to be used for
6318 replacing tables and other random data structures in Apache.
6321 *) Add some more error reporting to htpasswd in the case of problems
6322 generating or accessing the temporary file. Also, pass in a
6323 buffer if the implementation knows how to use it (i.e., if L_tmpnam
6324 is defined). [Ken Coar]
6326 *) Configure creates config.nice now containing your configure
6327 options. Syntax: ./config.nice [--more-options]
6330 *) Fix various return code problems in APR on Win32. For most of
6331 these, APR was returning APR_EEXIST instead of GetLastError()/
6332 WSAGetLastError(). [Jeff Trawick]
6334 *) Make piped logs work again in version 2.0
6337 *) Add VPATH support to UNIX build system of Apache and APR.
6340 *) Fix ap_tokenize_to_argv to respect the const arguments that are
6344 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
6345 Patch submitted to author.
6348 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
6349 /sbin in PATH on FreeBSD (all submitted to rse previously)
6352 *) Fix building Pthread-based MPMs on OpenBSD
6353 [Sascha Schumann] PR#26
6355 *) Fix ap_readdir() problem on systems where d_name[] field in
6356 struct dirent is declared with only one byte. (This problem only
6357 affected multithreaded builds.) This caused a segfault during
6358 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
6359 least). [Jeff Trawick]
6361 *) Fix some make-portability problems on at least Tru64, Irix
6363 [Sascha Schumann] PR#18, PR#39
6365 *) Add ap_sigwait() to support old-style sigwait() on systems
6366 like OS/390 and UnixWare.
6369 *) Add POSIX-thread flags for more platforms.
6372 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
6373 (on Unix, at least) to handle resolver errors. Fix a bug in
6374 the definition of APR_ENOMEM so that ap_strerror() can spit
6375 out the correct error message for it.
6378 Changes with Apache 2.0a3
6380 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
6383 *) API: *HOOK* macros now have an AP_ prefix
6386 *) Win32: Eliminate redundant calls to initialize winsock.
6387 [Tim Costello <timcostello ozemail.com.au>]
6389 *) Fix bugs initializing ungetchar for pipes.
6390 [Chia-liang Kao <clkao CirX.ORG>]
6392 *) The ab program in the src/support directory is now portable using
6396 *) Support directory is being compiled when the server is built
6399 *) The configure option --with-program-name has been added to allow
6400 developers to rename the executable at configure time. This also
6401 changes the name of the config files to match the executable's name.
6404 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
6405 containing version numbers. [Martin Pool]
6407 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
6408 Unix; access_log and error_log now created with these perms; non-
6409 Unix is unaffected [Jeff Trawick]
6411 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
6412 Replaced more magic numbers with MD5_DIGESTSIZE.
6413 [William Rowe, Roy Fielding]
6415 *) Win32: Get mod_auth_digest compiling and added to the Windows
6416 build environment. Not tested and I'd be suprised if it
6417 actually works. [Bill Stoddard]
6419 *) Revamp the Win32 make environment. Makefiles have been removed and
6420 Apache.dsw created to bring together all the pieces. Create new file
6421 os/win32/BaseAddr.ref to define module base addresses (to prevent
6422 dll relocation at start-up).
6423 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
6425 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
6426 of the \015, \012, and \015\012 constants with macros.
6429 *) Add ap_xlate_open() et al for translation of text between different
6430 character sets. The initial implementation requires iconv().
6433 *) More FAQs and answers from comp.infosystems.www.servers.unix.
6434 [Joshua Slive <slive finance.commerce.ubc.ca>]
6436 *) CGI output is being timed out now.
6439 *) Fix the problem with dieing quietly. dupfile now takes a pool which
6440 is used by the new apr file. There is no reason to create a new file
6441 with the same lifetime as the original file.
6444 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
6445 module base addresses. This will help shooting seg faults
6446 in the field. [William Rowe <wrowe lnd.com>]
6448 *) Update Apache on Windows documentation. Add new document
6449 describing how to compile Apache on Windows.
6450 [William Rowe <wrowe lnd.com>]
6452 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
6453 microseconds instead of seconds. Some storage leaks and other
6454 minor bugs in related code were fixed. [Jeff Trawick]
6456 *) Win32: First cut at getting mod_isapi working under 2.0
6457 [William Rowe <wrowe lnd.com>]
6459 *) First stab at getting mod_auth_digest working under 2.0
6460 quick change summary:
6461 - moved the random byte generation (ap_generate_random_bytes) into APR
6462 - now uses ap_time_t
6463 - compiles and runs on linux
6465 [Brian Martin <bmartin penguincomputing.com>]
6467 *) Win32: Move the space stripping of physical service names
6468 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
6469 unresolved symbol. Add dependency checking to the
6470 CreateService call to ensure TCPIP and AFP (winsock) is started
6472 [William Rowe <wrowe lnd.com>]
6474 *) Win32: Add code to perform latebinding on functions that may
6475 not exist on all levels of Windows where Apache runs. This
6476 is needed to allow Apache to start-up on Win95/98. All calls
6477 to non portable functions should be protected with
6478 ap_oslevel checks to prevent runtime segfaults.
6479 [William Rowe <wrowe lnd.com>]
6481 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
6483 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
6485 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
6486 This addresses PR 1623. Still need to address timing out runaway
6487 CGI scripts. [Bill Stoddard]
6489 *) Win32: Make ap_stat Windows 95/98 friendly
6490 [William Rowe <wrowe lnd.com>]
6492 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
6493 always fail. Need to initialise the dwOSVersionInfoSize member of the
6494 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
6497 The patch also enhances ap_get_oslevel (and the associated enum) to
6498 handle selected service packs for NT4, and adds recognition for
6499 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
6500 we can use ReadFileScatter and WriteFileGather in readwrite.c.
6501 [Tim Costello <Tim.Costello BTFinancialgroup.com>]
6503 *) Get mod_rewrite building and running, and mod_status building for Win NT
6504 [Allan Edwards <ake raleigh.ibm.com>]
6506 *) Patch to port mod_auth_db to the 2.0 api and also to support
6507 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
6508 2.7.7. It should work with version 1 as well but I haven't tested it.
6509 [Brian Martin <bmartin penguincomputing.com>]
6511 *) Get APR DSO code working under Windows. Includes cross platform
6513 [<Tim.Costello BTFinancialgroup.com>]
6515 *) Fix some of the Windows APR time functions.
6518 *) FAQ changes related to tidying up historical documents on the web site.
6519 [Joshua Slive <slive finance.commerce.ubc.ca>]
6521 *) Move Windows DSO code into APR.
6524 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
6525 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
6526 at build time. At this point, the server will not compile on Windows because
6527 of the recent DSO commits. Fixing those next.
6528 [Bill Rowe & Bill Stoddard]
6530 *) Added error checking for file I/O APR routines.
6531 [Jon Travis <jtravis covalent.net>]
6533 *) APR: Don't use the values of resolver error codes for the
6534 corresponding APR error codes. On Unix and Win32, return the
6535 proper APR error code after a resolver error. [Jeff Trawick]
6537 Changes with Apache 2.0a2
6539 *) Renamed the executable back to httpd on all platforms other
6543 *) Allow BeOS to survive restarts, log properly and a few
6544 small things it had problems with due to the way it setup
6545 users and groups. [David Reid]
6547 *) Get mod_rewrite working with APR locks
6548 [Paul Reder <rederpj raleigh.ibm.com>]
6550 *) Actually remove the sempahore when the lock cleanup routine
6551 is called on BeOS. [David Reid]
6553 *) Clear hook registrations between reads of the config file.
6554 When DSOs are unloaded and re-loaded the old hook pointers may
6555 no longer be valid. This fix eliminates potential segfaults.
6556 [Allan Edwards <ake raleigh.ibm.com>]
6558 *) Fix a problem with Sigfunc not being defined or bypassed
6559 if sigaction() wasn't found. [Jim Jagielski]
6561 *) Fix the locking mechanism on BSD variants. They now use fcntl
6562 locks. This allows the server to start and serve pages.
6565 *) First cut at getting the Win32 installer to work
6566 [William Rowe <wrowe lnd.com>]
6568 *) Get htpasswd compiling under Windows
6569 [William Rowe <wrowe lnd.com>]
6571 *) Change the log message for a bind() failure to show the
6572 interface and port number. [Jeff Trawick]
6574 *) Import the documentation from 1.3.12 and bring parts of it
6575 up-to-date with respect to the changes that have occurred
6579 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
6580 now logged correctly on BeOS.
6583 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
6584 Makefile.win includes the same user interface as the old
6586 [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>]
6588 *) Win32 exec now uses COMSPEC environment string for command
6589 shell path resolution.
6590 [William Rowe <wrowe lnd.com>] PR#3715
6592 *) Win32: ap_connect() was not returning correct error condition
6594 [Allen Prescott <allen clanprescott.com>]
6596 *) Win32: ap_open() was broken on Win9x because an NT-specific
6597 flag was passed to CreateFile. ap_puts() added an unnecessary
6599 [Jeff Trawick <trawick us.ibm.com>]
6601 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
6602 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
6603 confusing ee/et name and made all extensions language/dialect
6604 rather than country reflecting. Changed example files to
6605 explicit reflect the ISO charset and added a few common
6606 ones to the example config [dirkx]
6608 *) Extend external module capability. To use this, you call
6609 configure with --with-module=path/to/mod1,path/to/mod2,etc.
6612 *) Backported the various "default charset" fixes from 1.3.12,
6613 including the AddDefaultCharset directive. [Jim Jagielski]
6615 *) Added the capability to do ${ENVVAR} constructs in the
6616 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
6617 it does this on a line by line basis; i.e. if the envvar
6618 expands to something with spaces you have to protect it
6619 by adding quotes around it (Unless of course you expect it
6620 to contains more than one argument. Alternatively you
6621 can compile it on a per token basis; which is what people
6622 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
6623 hampers fancier hacks.
6624 [Dirk-Willem van Gulik]
6626 *) Changed the 'ErrorDocument' syntax in that it NO longer
6627 supports the asymetric
6629 ErrorDocument 301 "Some message
6631 Note the opening " quote, without a closing quote. It now
6632 has either the following syntaxes
6634 ErrorDocument XXX /local/uri
6635 ErrorDocument XXX http://valid/url
6636 ErrorDocument XXX "Some Message"
6638 The recognition heuristic is: if it has a space it
6639 is a message. If it has no spaces and starts with a /
6640 or is a valid URL then treat it that way. Otherwise it
6641 is assumed to be a message.
6643 This breaks backward compatibility but makes live a hell
6644 of a lot easier for GUI's and config file parsers.
6645 [Dirk-Willem van Gulik]
6647 *) Changed 'CacheNegotiatedDocs' from its present/not-present
6648 syntax into a 'on' or 'off' syntax. As it currently is the
6649 only non nesting token which uses NO_ARGS and thus is an
6650 absolute pain for any config interface automation. This
6651 breaks backward compatibility. [Dirk-Willem van Gulik]
6653 *) Add ability to add external modules to the build process. This is
6654 done with --with-module=/path/to/module. Modules can only be added
6655 as static modules at this point.
6658 Changes with Apache 2.0a1
6660 *) Fix FreeBSD 3.3 core dump.
6661 Basically, ap_initialize() needs to get called before
6662 create_process(), since create_process() passes op_on structure
6663 to semop() to get a lock, but op_on isn't initialized until
6664 ap_initialize() calls setup_lock(). Here is a slight
6665 rearrangement to main() which calls ap_initialize() earlier...
6666 [Jeff Trawick <trawick us.ibm.com>]
6668 *) Enable Apache to use sendfile/TransmitFile API
6669 [Bill Stoddard, David Reid, Paul Reder]
6671 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
6675 *) Make file I/O and network I/O writev/sendv APIs consistent.
6676 Eliminate use of ap_iovec_t and use Posix struct iovec.
6677 Use seperate variable on ap_writev to set the number of iovecs
6678 passed in and number of bytes written.
6681 *) Adapt file iol to use APR functions. Replaced ap_open_file()
6682 with ap_create_file_iol(). ap_create_file_iol() requires that
6683 the file be opened prior to the call using ap_open().
6686 *) Port mod_include and mod_cgi to 2.0
6687 [Paul Reder, Bill Stoddard]
6689 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
6690 bytes_read/bytes_written is always valid (never -1). Plus
6691 some fixes to buff.c to correct problems introduced by the
6692 errno => ap_status_t changes a while back. Plus a fix to
6693 chunked encoding introduced right at the beginning of 2.0.
6696 *) Revamped UNIX build system to use autoconf and libtool.
6697 [Manoj Kasichainula, Sascha Schumann]
6699 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>]
6701 *) SECURITY: More rigorous checking of Host: headers to fix security
6702 problems with mass name-based virtual hosting (whether using mod_rewrite
6703 or mod_vhost_alias).
6704 [Ben Hyde, Tony Finch]
6706 *) Add back support for UseCanonicalName in <Directory> containers.
6707 [Manoj Kasichainula]
6709 *) Added APLOG_STARTUP log type. This allows us to write an error
6710 message without any of the date and time information. As a part
6711 of this change, I also removed all of the calls to fprintf(stderr
6712 and replaced them with calls to ap_log_error using APLOG_STARTUP
6713 writing to stderr is no longer portable, because we don't direct
6714 stderr to the error log on all platforms.
6717 *) Convert error logging functions to take errno as an argument.
6718 This makes our error logs more portable, because some Windows API's
6719 don't set errno. This change allows us to still output a valid
6720 message on all of our platforms.
6723 *) mod_mime_magic runs in 2.0-dev now.
6724 [Paul Reder <rederpj raleigh.ibm.com>]
6726 *) sendfile has been added to APR.
6727 [John Zedlewski <zedlwski Princeton.EDU>]
6729 *) buff.c has been converted to no longer use errno.
6730 [Manoj Kasichainula]
6732 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
6733 interface adaption to APR functions did it. [Martin Kraemer]
6735 *) Support DSOs properly on 32-bit HP-UX 11.0
6736 [Dilip Khandekar <dilip cup.hp.com>]
6738 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
6739 [Ralf S. Engelschall]
6741 *) Cleaned APR build environment integration and bootstrap APR
6742 automatically for developers from src/Configure.
6743 [Ralf S. Engelschall]
6745 *) Fixed building of src/support/htpasswd.c
6746 [Ralf S. Engelschall]
6748 *) When generating the Location: header, mod_speling forgot
6749 to escape the spelling-fixed uri. (Forw-Port from 1.3)
6752 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
6754 *) Change all pools to APR contexts. This is the first step to
6755 incorporating APR into Apache. [Ryan Bloom]
6757 *) Move "handler not found" warning message to below the check
6758 for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding]
6759 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
6761 *) Support line-continuation feature in config.option file and
6762 allow the loading of multiple option sections at once via
6763 ``--with-option=<section1>,<section2>,...''
6764 [Ralf S. Engelschall]
6766 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
6768 Changes with Apache MPM
6770 *) Use asynchronous AcceptEx() and a completion port to accept and
6771 dispatch connections to threads in Windows NT/2000.
6774 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
6777 *) Implement the APACI --with-option facility
6778 (per default used the config.option file).
6779 [Ralf S. Engelschall]
6781 *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>]
6783 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
6784 Replace pre_connection module call with a register_hook call and
6785 implement pre_connection as a hook. The intent is that these hooks will
6786 be extended to allow Apache to be multi-protocol, and also to allow the
6787 calling order to be specified on a per-hook/per-module basis.
6790 *) Implement mpm_* methods as "modules". Each method gets its own
6791 subdir in src/modules (eg: src/modules/prefork). Selection
6792 of method uses Rule MPM_METHOD. [Jim Jagielski]
6794 *) Port the hybrid server from the apache-apr repository as
6795 mpm_mpmt_pthread. [Manoj Kasichainula]
6797 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
6798 amongst the unix MPMs.
6800 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
6801 signal handling for the new world order. [Dean Gaudet]
6803 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
6804 of alloc.c for now. [Dean Gaudet]
6806 *) Handle partial large writes correctly. [Ben Laurie]
6808 *) Eliminate conn_rec's pointer to server. All it knows is the base server
6809 based on IP/port. [Ben Laurie]
6811 *) Port a bunch of modules to the new module structure.
6812 ["Michael H. Voase" <mvoase midcoast.com.au>]
6814 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
6816 *) Basic restructuring to introduce the MPM concept; includes various
6817 changes to the module API... better described by
6818 docs/initial_blurb.txt. [Dean Gaudet]
6820 Changes with Apache pthreads
6822 *) New buff option added: BO_TIMEOUT. It describes the timeout for
6823 buff operations (generally over a network).
6824 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
6826 *) Created http_accept abstraction. Added 4 new functions (not exported):
6827 init_accept(), begin_accepting_requests(), get_request(),
6828 stop_accepting_requests() [Bill Stoddard]
6830 *) Fix to ap_rprintf call that allows mod_info to work properly.
6831 [James Morris <jmorris intercode.com.au>]
6833 *) user and ap_auth_type fields were moved from connection_rec to
6834 request_rec. [Ryan Bloom]
6836 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
6837 needed in a threaded server.
6839 *) Initial pthread implementation from from Dean's apache-nspr code.
6840 [Bill Stoddard, Ryan Bloom]
6843 Changes with Apache 1.3.9
6845 *) Remove bogus error message when a redirect doesn't set Location.
6846 Instead, use an empty string to avoid coredump if the error message
6847 was supposed to include a location. [Roy Fielding]
6849 *) Don't allow configure to include mod_auth_digest unless it is
6850 explicitly requested, even if the user asked for all modules.
6853 *) Translate module names to dll names for OS/2 so that they are no more
6854 than 8 characters long and have an extension of "dll" instead of "so".
6857 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
6858 Fix test-compile check to check for randbyte instead of trand32.
6859 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
6860 and tweak to make Amaya happier. [Ronald Tschalär]
6862 *) Ensure that the installed expat include files are world readable,
6863 just like the other header files. [Martin Kraemer]
6865 *) Fixed generated AddModule adjustments in APACI's `configure' script
6866 in order to allow (new) modules like mod_vhost_alias to be handled
6867 correctly (which was touched by the adjustments for mod_alias).
6868 [Ralf S. Engelschall]
6870 *) For binary builds, add -R flag to apachectl to work around the lack of
6871 an absolute path to the ./libexec directory where the libhttp.ep file
6872 is needed for SHARED_CORE architectures. [Randy Terbush]
6874 *) WIN32: Create the CGI script process as DETACHED. This may solve the
6875 problem observed by some Win95/98 users where they get CGI script
6876 output sent to the console. [Bill Stoddard]
6878 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
6879 routines are now called ap_base64* and are 'plain' (i.e., no
6880 pool access or anything clever). Inside util.c the routines acting
6881 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
6882 The oddly named ap_uuencode(), ap_uudecode() are kept around for
6883 now but deprecated. [dirkx]
6885 *) Clean up the base64 and SHA1 additions and make sure they are
6886 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
6887 files. [Roy Fielding]
6889 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
6890 checking. Allow compiling on VS 6.0. [Randy Terbush]
6892 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
6894 *) Use TestCompile to search for the truerand library (rather than blindly
6895 assuming its existence). If it is not found, complain (but do not
6896 exit - yet). [Martin Kraemer]
6898 *) We forgot to add the new exported function names to
6899 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
6901 *) Add description of -T command-line option to usage().
6902 [Ralf S. Engelschall]
6904 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
6905 searched only AFTER libap has been searched, because libap needs
6906 some symbols from libos. [Martin Kraemer]
6908 *) Fix conflict with original mod_digest related to the symbol of the
6909 module dispatch list (which has to be unique for DSO and follow the
6910 usual conventions for the installation procedure).
6911 [Ralf S. Engelschall]
6913 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
6914 for other platforms as well. [Martin Kraemer]
6916 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
6917 types by AP_LONG and replace reference to renamed variable 'ubuf'
6918 by 'buffer'. [Martin Kraemer]
6920 Changes with Apache 1.3.8 [not released]
6922 *) Flush the output buffer immediately after sending an error or redirect
6923 response, since the result may be needed by the client to abort a
6924 long data transfer or restart a series of pipelined requests.
6925 [Tom Vaughan <tvaughan aventail.com>, Roy Fielding]
6927 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
6928 [Ian Turner <iant sequent.com>] PR#4735
6930 *) Local struct mmap in http_core.c conflicted with system structure
6931 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
6933 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
6934 [Ronald Tschalär <ronald innovation.ch>]
6936 *) Fix a memory leak where the module counts were getting messed
6937 up across restarts. [David Harris <dharris drh.net>]
6939 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
6940 properly in mod_access.
6941 ["Paul J. Reder" <rederpj raleigh.ibm.com>] PR#4770
6943 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
6944 [Dmitry Khrustalev <dima bog.msu.su>] PR#3874
6946 *) PORT: Support for compaq/tandem/com.
6947 [Michael Ottati <michael.ottati compaq.com>, dirkx]
6949 *) Added SHA1 password encryption support to easy migration from
6950 Netscape servers. See support/SHA1 for more information.
6951 Caused the separation of ap_md5.c into md5, sha1 and a general
6952 ap_checkpass.c with just a validate_passwd routine. Added a
6953 couple of flags to support/htpasswd. Some reuse of the to64()
6954 function; hence renamed to ap_to64().
6955 [Dirk-Willem van Gulik, Clinton Wong <clintdw netcom.com>]
6957 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
6958 with ASCII/EBCDIC conversions in "ident" query.
6959 [David McCreedy <McCreedy us.ibm.com>]
6961 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
6962 Change "Power Macintosh" to Power* so if uname prints "Power Book"
6963 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
6965 *) Fix SIGSEGV on some systems because the Vary fix below included
6966 a call to table_do with a variable argument list that was not
6967 NULL terminated. Replaced with better implementation. [Roy Fielding]
6969 Changes with Apache 1.3.7 [not released]
6971 *) The "Vary" response header field is now sanitised right before
6972 the header is sent back to the client. Multiple "Vary" fields
6973 are combined, and duplicate tokens (e.g., "Vary: host, host" or
6974 "Vary: host, negotiate, host, accept-language") are reduced to
6975 single instances. This is a better solution than the force-no-vary
6976 one (which is still valid for clients that can't cope with Vary
6977 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
6979 *) Portability changes for BeOS. [David Reid <abb37 dial.pipex.com>]
6981 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
6982 least on Linux and FreeBSD for now.
6985 *) Win32: More apache -k restart work. Restarts are now honored
6986 immediately and connections in the listen queue are -not- lost.
6987 This is made possible by the use of the WSADuplicateSocket()
6988 call. The listeners are opened in the parent, duplicated, then
6989 the duplicates are passed to the child. The original listen sockets
6990 are not closed by the parent across a restart, thus the listen queue
6992 [Bill Stoddard <stoddard raleigh.ibm.com>]
6994 *) Fix handling of case when a client has sent "Expect: 100-continue"
6995 and we are going to respond with an error, but get stuck waiting to
6996 discard the body in the pointless hope of preserving the connection.
6997 [Roy Fielding, Joe Orton <jeo101 york.ac.uk>] PR#4499, PR#3806
6999 *) Fix 'configure' to work correctly with SysV-based versions of
7000 'tr' (consistent with Configure's use as well). [Jim Jagielski]
7002 *) apxs: Add "-S var=val" option which allows for override of CFG_*
7003 built-in values. Add "-e" option which works like -i but doesn't
7004 install the DSO; useful for editing httpd.conf with apxs. Fix
7005 editing code so that multiple invocations of apxs -a will not
7006 create duplicate LoadModule/AddModule entries; apxs can now be
7007 used to re- enable/disable a module. [Wilfredo Sanchez]
7009 *) Win32: Update the server to use Winsock 2. Specifically, link with
7010 ws2_32.lib rather than wsock32.lib. This gives us access to
7011 WSADuplcateSocket() in addition to some other enhanced comm APIs.
7012 Win 95 users may need to update their TCP/IP stack to pick up
7013 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
7014 [Bill Stoddard <stoddard raleigh.ibm.com>]
7016 *) Win32: Redirect CGI script stderr (script debug info) into the
7017 error.log when CGI scripts fail. This makes Apache on Win32
7018 behave more like Unix.
7019 [Bill Stoddard <stoddard raleigh.ibm.com>]
7021 *) Fixed `httpd' usage display: -D was missing.
7022 [Ralf S. Engelschall] PR#4614
7024 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
7025 [Ralf S. Engelschall] PR#4561, PR#4562
7027 *) OS/2: Fix problem with accept lock semaphores where server would die with
7028 "OS2SEM: Error 105 getting accept lock. Exiting!"
7029 [Brian Havard] PR#4505
7031 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
7032 [Randy Terbush <randy covalent.net>]
7034 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
7035 used by Demon Internet, Ltd. [Tony Finch <fanf demon.net>]
7037 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
7038 command potentially _is_ GCC. [Ralf S. Engelschall]
7040 *) Fix apxs build issues on AIX
7041 [Rasmus Lerdorf <rasmus raleigh.ibm.com>]
7043 *) DocumentRoot Checking: Under previous versions, when Apache
7044 first started up, it used to do a stat of each DocumentRoot to
7045 see if it existed and was a directory. If not, then an error
7046 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
7047 does not exist, you will get error messages in error_log. If
7048 the '-t' command line option is used (to check the configuration)
7049 the check of DocumentRoot IS performed. An additional command
7050 line option, '-T', has been added if you want to avoid the
7051 DocumentRoot check even when checking the configuration.
7054 *) Win32: The query switch "apache -S" didn't exit after showing the
7055 vhost settings. That was inconsistent with the other query functions.
7056 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
7058 *) Win32: Changed behaviour of apache -k restart.
7059 Previously, the server would drain all connections in the stack's
7060 listen queue before honoring the restart. On a busy server, this
7061 could take hours. Now, a restart is honored almost immediately.
7062 All connections in Apache's queues are handled but connections in
7063 the stack's listen queue are discarded. Restart triggered by
7064 MaxRequestPerChild is unchanged.
7065 [Bill Stoddard <stoddard raleigh.ibm.com>]
7067 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
7068 the accept loop. Good for a 5% performance boost. Cleaned up
7069 parent/child process management code.
7070 [Bill Stoddard <stoddard raleigh.ibm.com>]
7072 *) Added ceiling on file size for memory mapped files.
7073 [John Giannandrea <jg meer.net>] PR#4122
7075 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
7076 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
7077 [Henri Gomez <gomez slib.fr>, Ralf S. Engelschall]
7079 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
7080 use this at least for Expat. [Ralf S. Engelschall]
7082 *) Allow .module files to specify libraries with Lib:.
7085 *) Allow SetEnvIf[NoCase] to test environment variables as well
7086 as header fields and request attributes. [Ken Coar]
7088 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
7089 content-types are "text/html;parameters". PR#4524 [Ken Coar]
7091 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
7092 never accepted into any standard, and it opens up certain DoS
7093 attacks. [Koen Holtman <Koen.Holtman cern.ch>]
7095 *) TestCompile updated. We can now run programs and output the
7096 results during the Configure process. [ Jim Jagielski]
7098 *) The source is now quad (long long) aware as needed. Specifically,
7099 the Configure process determines the correct size of off_t and
7100 *void. When the OS/platform/compiler supports quads, ap_snprintf()
7101 provides for the 'q' format qualifier (if quads are not available,
7102 'q' is silently "demoted" to long). [Jim Jagielski]
7104 *) When the username or password fed to htpasswd is too long, include the
7105 size limit in the error message. Also report illegal characters
7106 (currently only ':') in the username. Add the size restrictions
7107 to the man page. [Ken Coar]
7109 *) Fixed the configure --without-support option so it doesn't result in
7110 an infinite loop. [Marc Slemko]
7112 *) Piped error logs could cause a segfault if an error occured
7113 during configuration after a restart.
7114 [Aidan Cully <aidan panix.com>] PR#4456
7116 *) If a "Location" field was stored in r->err_headers_out rather
7117 than r->headers_out, redirect processing wouldn't find it and
7118 the server would core dump on ap_escape_html(NULL). Check both
7119 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
7120 if Location isn't set. [Doug MacEachern, Ken Coar]
7122 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
7123 of the Expat 1.0.2 distribution. [Greg Stein]
7125 *) Replace regexec() calls with calls to a new API stub function
7126 ap_regexec(). This solves problems with DSO modules which use the regex
7127 library. [Jens-Uwe Mager <jum helios.de>, Ralf S. Engelschall]
7129 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
7130 environment variables can be set according to the protocol version
7131 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
7133 *) Add DSO support for OpenStep (Mach 4.2) platform.
7134 [Ralf S. Engelschall, Rex Dieter <rdieter math.unl.edu>] PR#3997
7136 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
7137 [Jan Gallo <gallo pvt.sk>] PR#3690, PR#4373
7139 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
7140 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
7142 *) Better DSO flags recognition on NetBSD platforms using ELF.
7143 [Todd Vierling <tv pobox.com>] PR#4310
7145 *) Always log months in english format for %t in mod_log_config.
7146 [Petr Lampa <lampa fee.vutbr.cz>] PR#4366, 679
7148 *) Support for server-parsed and multiview-determined ReadmeName and
7149 HeaderName files in mod_autoindex. Removed the restriction on
7150 "/"s in ReadmeName and HeaderName directives since the *sub_req*
7151 routines will deal with the access issues. (It's now possible to
7152 have {site|group|project|customer|...} wide readmes and headers.)
7153 [Raymond S Brand <rsbx rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
7156 *) When stat() fails, don't assume anything about the contents of
7157 the struct stat. [Ed Korthof <ed bitmechanic.com>]
7159 *) It's OK for a semop to return EINTR, just loop around and try
7160 again. [Dean Gaudet]
7162 *) Fix configuration engine re-entrant hangups, which solve a
7163 handful of problems seen with mod_perl <Perl> configuration sections
7164 [Salvador Ortiz Garcia <sog msg.com.mx>]
7166 *) Mac OS and Mac OS X Server now use the appropriate custom layout
7167 by default when building with APACI; allow for platform-specific
7168 variable defaults in configure. [Wilfredo Sanchez]
7170 *) Do setgid() before initgroups() in http_main; some platforms
7171 zap the grouplist when setgid() is called. This was fixed in
7172 suexec earlier, but the main httpd code missed the change.
7173 [Rob Saccoccio <robs InfiniteTechnology.com>] PR#2579
7175 *) Add recognition of .tgz as a gzipped tarchive.
7176 [Bertrand de Singly <bertrand.de-singly polytechnique.fr>] PR#2364
7178 *) mod_include's fsize/flastmod should allow only relative paths, just
7179 like "include file". [Jaroslav Benkovsky <benkovsk pha.pvt.cz>]
7181 *) OS/2: Add support for building loadable modules using DLLs.
7184 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
7187 *) Fix minor but annoying bug with the test for Configuration.tmpl
7188 being newer than Configuration so that it is less likely to fail
7189 when using APACI and shadow sources. [Wilfredo Sanchez]
7191 *) PORT: Add initial support for Mac OS (versions 10.0 and
7192 greater). Use Mac OS X Server layout for now. Clean up dyld code
7193 in unix/os.c, and don't install the dyld error handlers, which
7194 are no longer needed in Mac OS. [Wilfredo Sanchez]
7196 *) Rename Rhapsody layout to "Mac OS X Server". Change install
7197 locations to appropriate ones for user-built (as opposed to
7198 system) installs. [Wilfredo Sanchez]
7200 *) Modify mod_autoindex's handling of AddDescription so that the
7201 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
7203 *) Add functionality to the install-bindist.sh script created by
7204 binbuild.sh to use tar when copying distribution files to the
7205 serverroot. This allows upgrading an existing installation
7206 without nesting the new distribution in the old.
7208 install-bindist.sh now detects the local perl5 path to install
7209 apxs and dbmmanage with proper path to perl interpreter.
7211 Add an install-binsupport target which copies the source files
7212 for apxs and dbmmanage to bindist to allow these scripts to
7213 be properly installed relative to the destination serverroot.

7239 *) Fixed a bug in mod_dir that causes a child process will infinitely
7240 recurse when it attemps to handle a request for a directory wnd the
7241 value of the DirectoryIndex directive is a single dot. Also likely
7242 to happen for anyother values of DirectoryIndex that will map back

7315 than C. [Dean Gaudet] PR#3427
7317 *) Fix a memory leak which is exacerbated by certain configurations.
7318 [Dean Gaudet] PR#4225
7320 *) Prevent clobbering saved IFS values in APACI. [Jim Jagielski]
7322 *) Fix buffer overflows in ap_uuencode and ap_uudecode pointed out
7323 by "Peter 'Luna' Altberg <peter altberg.nu>" and PR#3422
7324 [Peter 'Luna' Altberg <peter altberg.nu>, Ronald Tschalär]
7326 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
7329 *) Correct an apparent typo: on the Windows and MPE platforms, the
7330 htpasswd utility was limiting passwords to only 8 characters.
7333 *) EBCDIC platforms: David submitted patches for two bugs in the
7334 MD5 digest port for EBCDIC machines:
7335 a) the htdigest utility overwrote the old contents of the digest file
7336 b) the Content-MD5 header value (ContentDigest directive) was wrong
7337 when the returned file was not converted from EBCDIC, but was a
7338 binary (e.g., image file) in the first place.
7339 [David McCreedy <mccreedy us.ibm.com>]
7341 *) support/htpasswd now permits the password to be specified on the
7342 command line with the '-b' switch. This is useful when passwords
7343 need to be maintained by scripts -- particularly in the Win32
7344 environment. [Ken Coar]
7346 *) Win32: Win32 multiple services patch. Added capability to install and
7347 run multiple copies of apache as individual services.
7350 apache -n apache1 -i -f c:/httpd.conf
7351 Installs apache as service 'apache1' and associates c:/httpd.conf
7354 Starts apache1 service.
7356 Stops apache1 service
7359 apache -n apache2 -i
7360 Installs apache as service 'apache2'. httpd.conf is located under
7361 the default server root (/apache/conf/httpd.conf).
7363 Starts apache2 service.
7366 apache -n apache3 -i -d c:/program files/apache
7367 Install apache as service 'apache3' and sets server root to
7368 c:/program files/apache.
7371 apache -n apache2 -k restart
7372 Restart apache2 service
7374 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
7376 *) Correct the signed/unsigned character handling for the MD5 routines;
7377 mismatches were causing compilation problems with gcc -pedantic and
7378 in the TPF cross-compilation. [Ken Coar]
7380 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
7381 a roughly 5 fold speed up. [Brian Havard]
7383 *) proxy ftp: instead of using the hardwired string "text/plain" as
7384 a fallback type for files served by the ftp proxy, use the
7385 ap_default_type() function to determine the configured type.
7386 This allows for special configurations like
7387 <Directory proxy:ftp://some.host>
7388 DefaultType gargle/blurb
7390 Additionally, add the Content-Encoding: header to FTP proxy replies
7391 when the encoding is defined (by the AddEncoding directive).
7392 Because it was missing, it was almost impossible to browse compressed
7393 files using the FTP proxy (works now perfectly in Communicator).
7394 The ftp proxy now also returns the Date: and Server: header lines (if not
7395 much else... This code is "somewhat" broken) like normal requests do.
7398 *) Be more smart in APACI's configure script when determining the UID/GID
7399 for User/Group directives and use the determined UID/GID to initialize
7400 the permissions on the proxycachedir.
7401 [Dirk-Willem van Gulik, Ralf S. Engelschall]
7403 *) Changed the forking-prior-to-cleanup in the proxy module to first
7404 check wether it actually needs to collect garbage. This reduces
7405 the number of fork()s from one/request to just the odd one an hour.
7406 [Dirk-Willem van Gulik]
7408 *) Added proxy, auth and header support to src/support/ab.c. Added a
7409 README file to src/support/
7410 [Dirk-Willem van Gulik]
7412 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.
7413 [Ralf S. Engelschall] PR#4050
7415 *) Add support for DSO module compilation on BSD/OS 3.x.
7416 [Randy Terbush, Covalent Technologies]
7418 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
7419 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
7420 option) were substituted with $(TARGET).conf, etc. Same for other strings
7421 with dots where the dot wasn't matched as plain text.
7422 [Ralf S. Engelschall]
7424 *) PORT: Add support for FreeBSD 4.x [Ralf S. Engelschall]
7426 *) Fix verbose output of APACI configure (option -v)
7427 [Martin Kraemer, Ralf S. Engelschall]
7429 Changes with Apache 1.3.6
7431 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
7433 Changes with Apache 1.3.5 [not released]
7435 *) M_INVALID needed a value within the scope of METHODS so that unknown
7436 methods can be access controlled. [Roy Fielding] PR#3821
7438 *) Added PassAllEnv; makes server's entire environment available
7439 to CGIs and SSIs executed within directive's scope. [Ken Coar]
7441 *) ap_uuencode() always added two trailing '='s and encoding of
7442 8 bit characters on a machine with signed char may produced
7443 incorrect results. Additionally ap_uuencode() should now
7444 work correctly on EBCDIC platforms.
7445 [Ronald Tschalär <ronald innovation.ch>] PR#3411
7447 *) WIN32: Binary installer now runs the configuration DLL before
7448 the reboot prompt (which is only given if MSVCRT.DLL system
7449 DLL is new or updated). This should avoid the configuration
7450 directory being empty after installation. [Paul Sutton]
7451 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
7453 *) WIN32: Binary installer now creates Start menu options to start
7454 and stop Apache as a console application and to uninstall
7455 the Apache service on NT. [Paul Sutton] PR#3741
7457 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
7459 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
7460 have been reported with flock() locking (probably related to kernel
7461 version). [Dean Gaudet] PR#2723, 3531
7463 *) Using APACI, the main config file (usually httpd.conf) was
7464 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
7465 <wsanchez apple.com>]
7467 *) PORT: AIX does not require the SHARED_CODE "hack"
7468 [Ryan Bloom <rbb raleigh.ibm.com>]
7470 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
7471 avoidance code added in 1.3.3.
7472 [Dean Gaudet, Jeff Lewis <lewis stanford.edu>] PR#3872
7474 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
7475 for 8-bit safeness. [Dean Gaudet]
7477 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
7478 because SPARCs have a small machine-specific maximum size for the Global
7479 Offset Table which is often exceeded when compiling one of the larger
7480 third-party modules with Apache. [Peter Urban <Peter.Urban epfl.ch>] PR#3977
7482 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
7483 DSO/DLL section because it's a directive from mod_status and isn't
7484 available before the DLL of mod_status is loaded.
7485 [Martin POESCHL <mpoeschl gmx.net>] PR#3936
7487 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
7488 continuation facility in Apache's configuration files which could
7489 lead to a buffer overflow situation.
7490 [Thomas Devanneaux <Thomas.Devanneaux enst.fr>] PR#3617
7492 *) Make documentation and error messages of APACI's --activate-module=FILE
7493 option more clear. [Jan Wolter <janc wwnet.net>] PR#3995
7495 *) Fix the gcc version check (for enabling the `inline' facility) to
7496 really support all future gcc versions >= 2.7 until we know more.
7497 [John Tobey <jtobey banta-im.com>] PR#3983
7499 *) Let APACI's configure script correctly complain for unknown --enable-XXX
7500 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
7502 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
7503 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
7504 possible buffer overflows. [Ralf S. Engelschall]
7506 *) Remove no longer used non-API function ap_single_module_init().
7507 [Ralf S. Engelschall]
7509 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
7512 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
7513 to make platform installations easier. [Wilfredo Sanchez]
7515 *) In configure, do not append the target name to the directory path if
7516 the path already contains "apache". [Ralf S. Engelschall]
7518 *) SIGPIPE is now ignored by the server core. The request write routines
7519 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
7520 correctly check for output errors and mark the connection as aborted.
7521 Replaced many direct (unchecked) calls to ap_b* routines with the
7522 analogous ap_r* calls. [Roy Fielding]
7524 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
7525 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
7526 Furthermore map lookups for non-existent keys are now cached as well.
7527 Additionally "txt" maps are now parsed with simple string functions
7528 instead of using ap_pregcomp(). As a side effect a bug that prevented
7529 the usage of keys containing the "," character was fixed.
7530 The changes drastically improve the performance when large rewrite maps
7532 [Michael van Elst <mlelstv serpens.swb.de>, Lars Eilebrecht] PR#3160
7534 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
7535 other than GET, and const'd the definition of method in request_rec.
7538 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
7540 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
7541 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
7543 *) Add %V to mod_log_config, this logs the hostname according to the
7544 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
7545 %v). Useful for mass vhosting. [Tony Finch <dot dotat.at>]
7547 *) Add support for \n and \t to mod_log_config, can be used to produce
7548 more reliable logs with multiline entries. [Tony Finch <dot dotat.at>]
7550 *) Fixed a few compiler nits. [John Bley <jbb6 acpub.duke.edu>]
7552 *) Added informative error messages for failed munmap() and fseek() calls
7553 in http_core.c. [John Bley, Roy Fielding]
7555 *) Added some informative error messages for some failed malloc()
7556 calls. [John Bley <jbb6 acpub.duke.edu>, Jim Jagielski]
7558 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
7559 is removed. This allows <Directory proxy:*> directives to work and
7560 prevents invalid requests from killing the process.
7561 [Brian Havard <brianh kheldar.apana.org.au>]
7563 *) Reorganised FAQ document.
7564 [Joshua Slive <slive finance.commerce.ubc.ca>] PR#2497
7566 *) src/support/: The ApacheBench benchmark program was overhauled by
7567 David N. Welton: you can now have it generate an HTML TABLE, presumably
7568 for integration into other HTML sources. David updated the ab man page
7569 as well and added some missing descriptions. Thanks!
7570 [David N. Welton <davidw prosa.it>]
7572 *) Win32: The filename validity checker now allows filenames containing
7573 characters in the range 0x80 to 0xff (for example accented characters).
7574 [Paul Sutton] PR#3890
7576 *) Added conditional logging based upon environment variables to
7577 mod_log_config. mod_log_referer and mod_log_agent
7578 are now deprecated. [Ken Coar]
7580 *) Allow apache acting as a proxy server to relay the real
7581 reason of a failure to a client rather than the "internal
7582 server error" it does currently. The general exposure mechanism
7583 can be triggered by any module by setting the "verbose-error-to"
7584 note to "*"; this allows more than just proxy errors to be exposed.
7585 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
7587 *) Moved man pages for ab and apachectrl to section 8.
7588 [Wilfredo Sanchez, Roy Fielding]
7590 *) Added -S option to install.sh so that options can be passed to
7591 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
7593 *) Tweak modules Makefile generated by Configure so that it handles
7594 the test case of no modules being selected. [<chaz reliant.com>]
7596 *) Added a <LimitExcept method ...> sectioning directive that allows
7597 the user to assign authentication control to any HTTP method that
7598 is *not* given in the argument list; i.e., the logical negation
7599 of the <Limit> directive. This is particularly useful for controlling
7600 access on methods unknown to the Apache core, but perhaps known by
7601 some module or CGI script. [Roy Fielding, Tony Finch]
7603 *) Prevent apachectl from complaining if the PIDFILE exists but
7604 does not contain a process id, as might occur if the server is
7605 being rapidly restarted. [Wilfredo Sanchez]
7607 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
7609 *) Entity tag comparisons for If-Match and If-None-Match were not being
7610 performed correctly -- weak tags might cause false positives. Also,
7611 strong comparison wasn't properly enforced in all cases.
7612 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
7614 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
7617 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
7618 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
7620 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
7621 to util.c for parsing an HTTP header field value to extract the next
7622 list item, taking into account the possible presence of nested comments,
7623 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
7624 insignificant whitespace and lowercases non-quoted tokens.
7625 [Roy Fielding] PR#2065
7627 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
7628 code different from 500. This allows the proxy to, e.g., return
7629 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
7631 *) Fix ordering of language variants for the case where the traditional
7632 negotiation algorithm is being used with multiple language variants
7633 and no Accept-Language. [James Treacy <treacy debian.org>] PR#3299, 3688
7635 *) Do not round the TCN quality calculation to 5 decimal places,
7636 unlike RFC 2296, because the calculation might need 12 decimal places
7637 to get the right result. [Roy Fielding]
7639 *) Remove unused code to disable transparent negotiation when
7640 negotiating on encoding only, as we now handle encoding too
7641 (though this is nonstandard for TCN), remove charset=ISO-8859-1
7642 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
7643 some debugging statements within mod_negotiation. [Koen Holtman]
7645 *) Fixed a rare memory corruption possibility in mod_dir if the index
7646 file is negotiable and no acceptable variant can be found.
7647 [Dean Gaudet, Roy Fielding, Martin Kraemer]
7649 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
7650 searching the Win32 registry for script interpreters.
7653 *) Win32: The compiled-in default filename for the error log is now
7654 error.log, which matches the default in the distributed httpd.conf.
7657 *) Win32: Any error messages from -i or -u command line options are now
7658 displayed on the console output rather than sent to the error log.
7659 Also the "Running Apache..." message is not output unless Apache is
7660 going to serve requests. [Paul Sutton]
7662 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
7663 and use a private significator ('$apr1$') to mark passwords as
7664 being smashed with our own algorithm. Also abstract the password
7665 checking into a new ap_validate_password() routine. [Ken Coar]
7667 *) Win32: The filename validity checker now allows "COM" but refuses
7668 access to "COM1" through "COM4". This allows filenames such
7669 as "com.name" to be served. [Paul Sutton] PR#3769.
7671 *) BS2000: Adapt to the new ufork() system call interface which will
7672 make subtasking easier on the OSD/POSIX mainframe environment.
7675 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
7676 ap_compat.h. [David White <david persimmon.com>] PR#3725
7678 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
7679 use `.db' instead of `.pag' not only for FreeBSD, but also when
7680 the NDBM library looks like Berkeley-DB based.
7681 [Ralf S. Engelschall] PR#3773
7683 *) Add ability to handle DES or MD5 authentication passwords.
7684 [Ryan Bloom <rbb Raleigh.IBM.Com>]
7686 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
7688 *) SECURITY: Avoid some buffer overflow problems when escaping
7689 quoted strings. (This overflow was on the heap and we believe
7690 impossible to exploit.) [Rick Perry <perry ece.vill.edu>]
7692 *) Let src/Configure be aware of CFLAGS options starting with plus
7693 signs as it's the case for the HP/UX compiler.
7694 [Doug Yatcilla <yatcilda umdnj.edu>] PR#3681
7696 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
7697 and check to see if the tar we wind up with supports '-h'.
7698 [Jim Jagielski] PR#3671
7700 *) A consistent and conservative style for all shell scripts has been
7701 implemented. Basically, all shell string tests use the traditional
7702 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
7703 to protect against bare null variable strings (ie: wrapping both
7704 sides with double quotes and prepending 'x'). 'x' was chosen
7705 because it's more universal and hopefully easier for old shell
7706 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
7709 *) The status module now prints out both the main server generation as
7710 well as the generation of each process. Also, the vhost info is
7711 printed with '?notable'. [Jim Jagielski]
7713 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
7714 and this makes its functions available to things in src/support.
7717 Changes with Apache 1.3.4
7719 *) Renamed macros status_drops_connection to ap_status_drops_connection
7720 and vestigial scan_script_header to ap_scan_script_header_err,
7721 mostly for aesthetic reasons. [Roy Fielding]
7723 *) The query switch "httpd -S" didn't exit after showing the
7724 vhost settings. That was inconsistent with the other query functions.
7727 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
7728 filename to the end of the STANDARD_MODULE_STUFF. Its
7729 presence at the beginning prevented reporting of the filename
7730 for modules compiled before 1 January 1999. [Ken Coar]
7732 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
7733 to detect and prevent access to special DOS device file names.
7734 [Paul Sutton, Ken Parzygnat]
7736 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
7737 and Makefile_win32_debug.txt (debug build) that work on Win95.
7738 Run each of the following from the src directory:
7739 nmake /f Makefile_win32.txt # compiles normal build
7740 nmake /f Makefile_win32.txt install # compiles and installs
7741 nmake /f Makefile_win32.txt clean # removes compiled junk
7742 nmake /f Makefile_win32_debug.txt # compiles debug build
7743 nmake /f Makefile_win32_debug.txt install
7744 nmake /f Makefile_win32_debug.txt clean
7747 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
7748 to build binary distributions. [Lars Eilebrecht]
7750 *) IndexOptions SuppressColumnSorting only turned off making
7751 the column headers anchors; you could still change the display
7752 order by manually adding a '?N=A' or similar query string to the
7753 URL. Now SuppressColumnSorting locks in the sort order so
7754 it can't be overridden this way. [Ken Coar]
7756 *) Added IndexOrderDefault directive to supply a default sort order
7757 for FancyIndexed directory listings. [Ken Coar] PR#1699
7759 *) Change the ap_assert macro to a variant that works on all platforms.
7760 [Richard Prinz <richard.prinz cso.net>] PR#2575
7762 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
7763 search for an underscore on dlsym() (as it's already the case
7764 for FreeBSD 3.0). [Todd Vierling <tv pobox.com>] PR#2462
7766 *) Small fix for mod_env.html: The module was documented as to be _not_
7767 compiled into Apache per default, although it _IS_ compiled into
7768 Apache per default. [Sim Harbert <sim mindspring.com>] PR#3572
7770 *) Instead of fixing a bug in the generation procedure for config.status (a
7771 backslash was missing) we remove the bug together with it's complete
7772 context because the special cases of the past can now no longer occur
7773 because of the recent magic for the --with-layout default.
7774 [Ralf S. Engelschall] PR#3590
7776 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
7777 making sure the src/support/ tools are _forced_ to be build last (they
7778 depend on other libraries).
7779 [Markus Theissinger <markus.theissinger gmx.de>]
7781 *) Fix installation procedure: Now that os-inline.c is actually used (a
7782 recently fixed bug prevented this) we need to also install os-include.c
7783 in addition to os.h into the PREFIX/include/ location or building of
7784 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
7786 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
7787 allow us to distinguish between a garbled DSO (or even a file which isn't
7788 an Apache module DSO at all) and a DSO which doesn't match the current
7789 Apache API. [Ralf S. Engelschall] PR#3152
7791 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
7792 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
7793 match case insensitive (this especially avoids nasty patterns like
7794 `[tT][eE][sS][tT]'). Second two additional internal map functions
7795 `escape' and `unescape' were added which can be used to escape/unescape
7796 to/from hex-encodings in URLs parts (this is especially useful in
7797 combination with map lookups).
7798 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
7800 *) Renamed the macro escape_uri() to ap_escape_uri() which was
7801 forgotten (because it was a macro) in the symbol renaming process.
7802 [Ralf S. Engelschall]
7804 *) Fix some inconsistencies related to the scopes of directives. The only
7805 user visible change is that the directives `UseCanonicalName' and
7806 `ContentDigest' now use the (more correct) `Options' scope instead of
7807 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
7809 *) Using DSO, the Server token was being mangled. Specifically, the
7810 module's token was being added first before the Apache token. This
7811 has been fixed. [Jim Jagielski]
7813 *) Major overhaul of mod_negotiation.c, part 2.
7814 - properly handle "identity" within Accept-Encoding.
7815 - allow encoded variants in RVSA negotiation and let them appear in
7816 the Alternates field using the non-standard "encoding" tag-list.
7817 - fixed both negotiation algorithms so that an explicitly accepted
7818 encoding is preferred over no encoding if "identity" is not
7819 included within Accept-Encoding.
7820 - added ap_array_pstrcat() to alloc.c for efficient concatenation
7821 of large substring sequences.
7822 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
7825 *) Major overhaul of mod_negotiation.c, part 1.
7826 - cleanups to mod_negotiation comments and code structure
7827 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
7828 support for everything in the upcoming HTTP/1.1
7829 revision (draft-ietf-http-v11-spec-rev-06.txt).
7830 - language tag matching also handles tags with more than 2
7832 - empty Accept, Accept-Language, Accept-Charset headers are
7833 processed correctly; previously an empty header would make all
7834 values acceptable instead of unacceptable.
7835 - allowed for q values in Accept-Encoding
7836 - added support for transparent content negotiation (rfc2295 and
7837 rfc2296) (though we do not implement all features in these drafts,
7838 e.g. no feature negotiation). Removed old experimental version.
7839 - implemented 'structured entity tags' for better cache correctness
7840 (structured entity tags ensure that caches which can deal with Vary
7841 will (eventually) be updated if the set of variants on the server
7843 - this involved adding a vlist_validator element to request_rec
7844 - this involved adding the ap_make_etag() function to the global API
7845 - modified guessing of charsets used by Apache negotiation algorithm
7846 to guess 'no charset' if the variant is not a text/* type
7847 - added code to sort multiviews variants into a canonical order so that
7848 negotiation results are consistent across backup/restores and mirrors
7849 - removed possibility of a type map file resolving to another type map
7850 file as its best variant

7869 This improves the make environment available to TestCompile and
7870 the *.module scripts. [Martin Kraemer]
7872 *) The hashbang emulation code in ap_execve.c would interpret
7873 #!/hashbang/scripts correctly, but failed to fall back to a
7874 standard shell for scripts which did NOT start with #!
7875 Now SHELL_PATH is started in these cases. [Martin Kraemer]
7877 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg lentil.org>]
7880 *) Update APXS manual page: some -q option arguments were missing
7881 and another was incorrect. [Mark Anderson <mda discerning.com>] PR#3553
7883 *) Cleanup the command line options: `-?' was documented to show
7884 the usage list but does it with an error because `?' is not a valid
7885 command. OTOH a lot of users expect `-h' to print such a usage list and
7886 instead are annoyed for ages by our huge unreadable list of directives.
7887 So we now changed the command line options this way:
7889 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
7890 very similar to the popular linker option.
7892 Intent: while -l gives the small list of modules, -L now gives the
7893 large list of directives implemented by these modules. This is also
7894 consistent with -v (short version info) and -V (large version info).
7896 Intent: it's now the expected option ;-)
7897 The manual page was adjusted accordingly.

7900 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
7901 wasn't defined. [Rick Franchuk <rickf transpect.net>]
7903 *) Removed recently introduced bugs and disfigurements in APACI:
7904 o fixed argument line processing: using $args was broken: It was not
7905 initialized and using args="$args $apc_option" and even args="$args
7906 \"$apc_option\"" fails in the second processing round for any arguments
7907 containing whitespaces. The only correct way is to use the construct
7908 "$@" (but not possible here) or iterate _both_ times over the implicit
7909 argument line (no argument to for-loop) which is what we now use.
7910 o make --with-layout=Apache the default without creating
7911 redundancy (copying the --with-layout block in the argument parsing
7912 loop). We achieve this by using the "$@" construct together with the
7913 `set' command to prepend --with-layout=Apache to the command line in
7914 case --with-layout is not used.
7915 o fixed auto-suffix handling now that config.layout exists.
7916 Paths which are auto-suffixed are marked with a trailing plus sign in
7917 config.layout and every path now can be marked this way (not only the
7918 four paths for which we do it currently). Additionally the suffix is
7919 no longer a static one. Instead it's now `/<target>' where <target> is
7920 the argument of the --target option or per default `httpd'.
7921 o allow also tabs (and only spaces) where we match whitespaces
7922 o various fixes and cleanups related to used shell coding style
7923 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
7924 o trimmed output of --help to fit into 80 columns

7950 differenciate between modules when one module name was a postfix of

7986 *) Fixed possible (but harmless in practice) bug in the DBM lookup
7987 procedure of mod_rewrite: very long keys were truncated.
7988 [Ralf S. Engelschall]
7990 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
7991 identifier, currently "Apache" and "GNU" are pre-defined in the file
7992 config.layout. Custom layouts are possible by using FILE:ID as the
7993 argument where the layout ID is taken from FILE.
7995 The config.layout file consists of <Layout ID>..</Layout> sections
7996 where inside those sections "path_variable: path_value" pairs can be
7997 specified. These lines are converted to path_variable='path_value'.
7999 *) Add a DefaultLanguage directive so that files missing a language
8000 extension (e.g., .fr, .de) can be labelled as being some other
8001 default language. DefaultLanguage can appear in <Directory> and
8002 <Files> containers as well as .htaccess files. [Paul Sutton]
8005 *) Fix TARGET configuration when configuring and installing using
8006 APACI configure. TARGET now defines the basename of the configuration

8116 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
8117 in the Configuration[.apaci] file. Two special and important variants are
8118 supported for the option argument: first BEGIN:foo which permutes module
8119 mod_foo with the begin of the module list, i.e. it `moves' the module to
8120 the begin of the list (gives it lowest priority). And second foo:END
8121 which permutes mod_foo with the end of the module list, i.e. it `moves'
8122 the module to the end of the list (gives it highest priority).

8313 *) Fix bug in ap_remove_module(), which caused problems for dso's
8314 who were the top_module. [Doug MacEachern]
8316 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
8317 mod_auth_db to both be friendly to users who wants to use this version
8318 and to avoid problems under platforms where only version 2.x is present.
8319 [Dan Jacobowitz <drow false.org>, Ralf S. Engelschall]
8321 *) When using ap_log_rerror(), make the error message available to the
8322 *ERROR_NOTES envariables by default. [Ken Coar]
8324 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
8325 You now must define a BS2000Account name for the server User.
8326 This has fewer security implications than the old approach.
8329 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
8330 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
8331 platform to make the braindead HPUX linker happy. Notice, for the module
8332 DSOs we don't have to use this, because these are loaded manually (and
8333 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
8335 *) Remove 64 thread limit on Win32.
8336 [Bill Stoddard <stoddard raleigh.ibm.com>]
8338 *) Remove redundant substitutions in top-level Makefile.tmpl.
8339 [Ralf S. Engelschall]
8341 *) Fix APACI's `Group' configuration adjustment - especially for Linux
8342 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
8344 *) Make PrintPath work generically instead of having one version
8345 strictly for OS/2. [Jim Jagielski, Brian Havard]
8347 *) Fix the recently introduced C header file checking: We now use the C
8348 pre-processor pass only (and no longer the complete compiler pass) to
8349 determine whether a C header file exists or not. Because only this way
8350 we're safe against inter-header dependencies (which caused horrible
8351 portability problems). The only drawback is that we now have a CPP
8352 configuration variable which has to be determined first (we do a similar
8353 approach as GNU Autoconf does here). When all fails the user still has
8354 the possibility to override it manually via APACI or src/Configuration.
8355 As a fallback for the header check itself we can directly check the
8356 existance of the file under /usr/include, too.
8357 [Ralf S. Engelschall] PR#2777
8359 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
8360 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
8361 ap_private_extern defined to hide symbols that conflict with loaded
8362 dynamic libraries on the NEXT and RHAPSODY platforms.
8363 [Wilfredo Sanchez <wsanchez apple.com>]
8365 *) Delete PID file on clean shutdowns.
8366 [Charles Randall <crandall matchlogic.com>] PR#2947
8368 *) Fix mod_auth_*.html documents: NSCA -> NCSA
8369 [Youichirou Koga <y-koga jp.FreeBSD.org>] PR#2991
8371 *) Fix INSTALL document: www.gnu.ai.mit.edu -> www.gnu.org
8372 [Karl Berry <karl gnu.org>] PR#2994
8374 *) Fix dbmmanage.1 manual page.
8375 [Youichirou Koga <y-koga jp.FreeBSD.org>] PR#2992
8377 *) Fix possible buffer overflow situation in suexec.c.
8378 [Jeff Stewart <jws purdue.edu>] PR#2790
8380 *) Add some more LIBS for the SCO5 platform which are needed for the already
8381 used -lprot. It's actually a bug in SCO5, of course.
8382 [Ronald Record <rr sco.com>] PR#2533
8384 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
8385 trailing slash problem. [Jon Drukman <jsd gamespot.com>] PR#2933
8387 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
8388 platform, because it's only supported under version 4.0 and higher. But
8389 because our GuessOS is still unaware of Digital UNIX versions and the
8390 -msym is just to optimize the DSO statup time a little bit it's safe and
8391 best when we leave it out now. [Ralf S. Engelschall] PR#2969
8393 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
8394 functions: First all three functions no longer fail on strings containing
8395 "%" chars and second ap_log_printf() no longer does a double-formatting
8396 (instead it directly passes through the message to be formatted to the
8397 real internal formatting function). [Ralf S. Engelschall] PR#2941
8399 *) Allow "Include" directives anywhere in the server config
8400 files (but not .htaccess files). [Ken Coar] PR#2727
8402 *) The proxy was refusing to serve CONNECT requests except to
8403 port 443 (https://) and 563 (snews://). The new AllowCONNECT
8404 directive allows the configuration of the ports to which a
8405 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
8407 *) mod_expires will now act on content that is not sent from a file
8408 on disk. Previously it would never add an Expires: header to
8409 any response that did not come from a file on disk; the only
8410 case where it still doesn't (and can't) add one for that type of
8411 content is if you are using a modification date based setting.
8412 [Marc Slemko, Paul Phillips <paulp go2net.com>]
8414 *) Problems encountered during .htaccess parsing or CGI execution
8415 that lead to a "500 Server Error" condition now provide explanatory
8416 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
8419 *) Add NameWidth keyword to IndexOptions directive so that the
8420 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
8423 *) Recognize lowercase _and_ uppercase `uname' results under
8424 SCO OpenServer. [David Coelho <drc ppt.com>]
8426 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
8427 a common problem of (mis-administrated?) IIS servers, make the apache
8428 proxy immune to these errors (and ignore the duplicates, but log
8429 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
8431 *) The <IfModule and <IfDefine block starting directives now only
8432 allow exactly one argument. Previously, the optional negation
8433 character '!' could be separated by whitespace without a syntax
8434 error being reported, albeit defeating the IfModule functionality
8435 (enclosed directives would ALWAYS be executed). By using the
8436 stricter syntax, these hard-to-track errors can be avoided.
8439 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
8440 cause the standalone FancyIndexing directive to logically OR
8441 into any existing IndexOptions settings rather than wiping
8442 them out. [Ken Coar]
8444 *) Changes in ftp proxy: make URL parsing simpler by using the
8446 + Add display of the "current directory" in cases where it's
8447 different from the supplied path (e.g., ftp://user@host/ lives
8448 in /home/user, not in /, therefore clicking on "../" in the
8449 starting directory might send us to /home/).
8450 + When ftp login fails, (esp. when a user name was part of the
8451 URL already), we now return [401 Unauthorized ] to allow the
8452 browser to pop up an authorization dialog. This makes passwords
8453 slightly less visible (they don't appear in the regular log files)
8454 and implements a functionality that other www proxy servers
8458 *) Triggered by the recent "Via:" header changes, the proxy module would
8459 dump core for replies with invalid headers (e.g., duplicate
8460 "HTTP/1.0 200 OK" lines). These errors are now logged and the
8461 core dump is avoided. Also, broken replies are not cached.
8462 [Martin Kraemer] PR#2914
8464 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
8465 plop gmon.out profile data for each child [Doug MacEachern]
8467 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
8468 config.status script to be immune against arguments with whitespaces.
8469 [Yves Arrouye <yves apple.com>] PR#2866
8471 *) Replace the inlined information grabbing stuff for the configuration
8472 adjustment feature (no --without-confadjust) with calls to a new helper
8473 script `buildinfo.sh' which is both more flexible and already proofed to
8474 be more robust against platform differences. This mainly fixes the
8475 recently occured ``sed: command garbled: ...'' problems.
8476 [Ralf S. Engelschall] PR#2776, PR#2848
8478 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
8479 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
8480 without complains after we recently added the POST feature.
8481 [Ralf S. Engelschall]
8483 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
8484 modules as API functions and we forgot them at the big symbol renaming.
8485 [Ralf S. Engelschall]
8487 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
8488 [Youichirou Koga <y-koga jp.FreeBSD.ORG>] PR#2895
8490 *) Dynamically size the filename column of mod_autoindex output.
8493 *) Add the ability to do POST requests to the ab benchmarking tool.
8494 [Kurt Sussman <kls best.com>] PR#2871
8496 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
8497 5 to 10 because there are some users out there who always have 5 to 8
8498 variables in one RewriteRule and had to patch mod_rewrite.h for every
8499 release. So 15 should be now more than enough, even for them. (I never
8500 needed more than 4 in my RewriteRules ;-)
8501 [Ralf S. Engelschall]
8503 *) Make the proxy generate and understand Via: headers
8506 *) Change the proxy to use tables instead of array_headers for
8507 the header lines. [Martin Kraemer]
8509 *) Make sure the config.status file is not overridden when just
8510 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
8512 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
8513 provide a way to trace API changes that add functionality but do
8514 not create a compatibility issue for precompiled modules, etc.
8515 See include/ap_mmn.h for more details. [Randy Terbush]
8517 *) Fix suexec installation under `make install root=xxx' situation.
8518 [Ralf S. Engelschall]
8520 *) Extend the output of the -V switch to include the paths of all
8521 compiled-in configuration files, if they were overridden at
8522 compile time, for least astonishment of the user.
8525 *) When READing a request in ExtendedStatus mode, the "old"
8526 vhost, request and client information is not displayed.
8529 *) STATUS is no longer available. Full status information now
8530 run-time configurable using the ExtendedStatus directive.
8533 *) SECURITY [CAN-1999-1199] (cve.mitre.org):
8534 Eliminate O(n^2) space DoS attacks (and other O(n^2)
8535 cpu time attacks) in header parsing. Add ap_overlap_tables(),
8536 a function which can be used to perform bulk update operations
8537 on tables in a more efficient manner.
8540 *) SECURITY: Added compile-time and configurable limits for
8541 various aspects of reading a client request to avoid some simple
8542 denial of service attacks, including limits on maximum request-line
8543 size (LimitRequestLine), number of header fields (LimitRequestFields),
8544 and size of any one header field (LimitRequestFieldsize). Also added
8545 a configurable directive LimitRequestBody for limiting the size of the
8546 request message body. [Roy Fielding]
8548 *) Make status module aware of DNS and logging states, even if
8549 STATUS not defined. [Jim Jagielski]
8551 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
8553 *) Enhance mod_speling so that CheckSpelling can be used in
8554 <Directory> containers and .htaccess files. [Ken Coar]
8556 *) API: new ap_custom_response() function for hooking into the
8557 ErrorDocument mechanism at runtime [Doug MacEachern]
8559 *) API: new ap_uuencode() function [Doug MacEachern]
8561 *) API: scan_script_header_err_core() now "public" and renamed
8562 ap_scan_script_header_err_core() [Doug MacEachern]
8564 *) The 'status' module will now show the process pid's and their
8565 state even without full STATUS accounting. [Jim Jagielski]
8567 *) Restore the client IP address to the error log messages, this
8568 was lost during the transition from 1.2 to 1.3. Add a new
8569 function ap_log_rerror() which takes a request_rec * and
8570 formats it appropriately. [Dean Gaudet] PR#2661
8572 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
8573 whitespace in input lines -- including within quoted strings.
8575 but leading and trailing whitespace should continue to be
8576 stripped [Martin Kraemer]
8578 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
8579 the ugly use of an env. variable and use command-line args for
8580 alternate $PATH. Make more like advanced 'type's as well.
8583 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
8584 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
8585 <alain.st-denis ec.gc.ca>] PR#2736
8587 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
8589 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
8590 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
8591 directory was renamed to src/os/os2/ for consistency.
8592 [Brian Havard, Ralf S. Engelschall]
8594 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
8595 files (here modules) against other DSO files (here shared libraries).
8596 This is done by determining a subset of LIBS which can be safely used for
8597 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
8598 disabled for all platforms to avoid problems with this (experimental)
8599 rule. But we provide it now for those people how ran into problems and
8600 want to came out by forcing linking against DSOs.
8601 [Ralf S. Engelschall] PR#2587
8603 *) Fix suEXEC start message: Has to be of `notice' level to really get
8604 printed together with the standard startup message because the `notice'
8605 level is handled special inside ap_log_error() for startup messages.
8606 [Ralf S. Engelschall] PR#2761 PR#2761 PR#2765
8608 *) Add correct `model' MIME types from RFC2077 to mime.types file.
8609 [Ralf S. Engelschall] PR#2732
8611 *) Fixed examples in mod_rewrite.html document.
8612 [Youichirou Koga <y-koga jp.FreeBSD.org>, Ralf S. Engelschall] PR#2756
8614 *) Allow ap_read_request errors to propagate through the normal request
8615 handling loop so that the connection can be properly closed with
8616 lingering_close, thus avoiding a potential TCP reset that would
8617 cause the client to miss the HTTP error response. [Roy Fielding]
8619 *) One more portability fix for APACI shadow tree support: Swap order of awk
8620 and sed in top-level configure script to avoid sed fails on some
8621 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
8622 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729
8624 *) PORT: NEC EWS4800 support.
8625 [MATSUURA Takanori <t-matsuu protein.osaka-u.ac.jp>]
8627 *) Fix a segfault in the proxy on OS/2. [Brian Havard]
8629 *) Fix Win32 part of ap_spawn_child() by providing a reasonable child_info
8630 structure instead of just NULL. This fixes at least the RewriteMap
8631 programs under Win32. [Marco De Michele <mdemichele tin.it>] PR#2483
8633 *) Add workaround to top-level `configure' script for brain dead
8634 `echo' commands which interpet escape sequences per default.
8635 [Ralf S. Engelschall] PR#2654
8637 *) Make sure that the path to the Perl interpreter is correctly
8638 adjusted under `make install' also for the printenv CGI script.
8639 [Ralf S. Engelschall] PR#2595
8641 *) Update the mod_rewrite.html document to correctly reflect the situation
8642 of the `proxy' (`[P]') feature. [Ralf S. Engelschall] PR#2679
8644 *) Fix `install-includes' sub-target of `install' target in top-level
8645 Makefile.tmpl: The umask+cp approach didn't work as expected (especially
8646 for users which extracted the distribution under 'umask 077'), so replace
8647 it by an explicit cp+chmod approach.
8648 [Richard Lloyd, Curt Sampson, Ralf S. Engelschall] PR#2656 PR#2626
8650 *) Fix `distclean' and `clean' targets in src/Makefile.tmpl to have same
8651 behavior and to cleanup correctly even under enabled SHARED_CORE rule.
8652 [Ralf S. Engelschall]
8654 *) Use a more straight forward and thus less problematic Sed command in
8655 src/helper/mkdir.sh script. [Ralf S. Engelschall]
8657 *) Make sure the `configure' scripts doesn't fail when trying to guess the
8658 domainname of the machine and there are multiple `domainname' and
8659 `search' entries in /etc/resolv.conf.
8660 [Ralf S. Engelschall] PR#2710
8662 *) Add note about the SHARED_CORE requirement on some platforms also to the
8663 INSTALL file because a lot of users don't read htdocs/manual/dso.html
8664 first. [Ralf S. Engelschall] PR#2701
8666 *) Fix document "hyperlink" for dso.html in src/Configuration.tmpl
8667 [Knut A.Syed <Knut.Syed nhh.no>] PR#2674
8669 *) Modify mod_rewrite to update the Vary response field if the URL rewriting
8670 engine does any manipulations or decisions based upon request fields.
8673 *) Document the special APACI behavior for installation paths where
8674 ``/apache'' is appended to paths under some (well defined, of course)
8675 situations to prevent pollution of system locations with Apache files.
8676 [Ralf S. Engelschall] PR#2660
8678 *) Fixed problem with buffered response message not being sent for
8679 the read_request error conditions of URI-too-long (414) and
8680 malformed header fields (400). [Roy Fielding] PR#2646
8682 *) Add support for the Max-Forwards: header line required by RFC2068 for
8683 the TRACE method. This allows apache to TRACE along a chain of proxies
8684 up to a predetermined depth. [Martin Kraemer]
8686 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled
8687 (compilers complained) and the .so.V.R.P filename extension was adjusted
8688 to correctly reflect the 1.3.2 version.
8689 [Ralf S. Engelschall] PR#2644
8691 *) SECURITY: Plug "..." and other canonicalization holes under OS/2.
8694 *) PORT: implement serialized accepts for OS/2. [Brian Havard]
8696 *) mod_include had problems with the fsize and flastmod directives
8697 under WIN32. Fix also avoids the minor security hole of using
8698 ".." paths for fsize and flastmod.
8699 [Manoj Kasichainula <manojk raleigh.ibm.com>] PR#2355

8703 Changes with Apache 1.3.1
8705 *) Disable the incorrect entry for application/msword in the
8706 mod_mime_magic "magic" file because it also matches other Office
8707 documents. [Ralf S. Engelschall] PR#2608
8709 *) Fix broken RANLIB handling in src/Configure (the entry from
8710 src/Configuration.tmpl was ignored) and additionally force RANLIB to
8711 /bin/true under HP/UX where ranlib exists but is deprecated.
8712 [Ralf S. Engelschall] PR#2627
8714 *) 'apachectl status' failed on some systems.
8715 [Steve VanDevender <stevev darkwing.uoregon.edu>, Lars Eilebrecht] PR#2613
8717 *) Add new flags for ap_unparse_uri_components() to make it generate
8718 the scheme://sitepart string only, or to omit the query string.
8721 *) WIN32: Canonicalize ServerRoot before checking to see if it
8722 is a valid directory. The failure to do this caused certain
8723 ServerRoot settings (eg. "ServerRoot /apache") to be improperly
8724 rejected. [Marc Slemko]
8726 *) Global renaming of C header files to both get rid of conflicts with third
8727 party packages and to again reach consistency:
8728 1. conf.h -> ap_config.h
8729 2. conf_auto.h -> ap_config_auto.h \ these are now merged
8730 3. ap_config.h -> ap_config_auto.h / in the config process
8731 4. compat.h -> ap_compat.h
8732 5. apctype.h -> ap_ctype.h
8733 Backward compatibility files for conf.h and compat.h were created.
8735 *) mod_mmap_static will no longer take action on requests unless at
8736 least one "mmapfile" directive is present in the configuration.
8737 This experimental module has to do some black magic to operate
8738 inside the current API and thus creates side-effects for other
8739 modules under some circumstances.
8740 [Ralf S. Engelschall]

8743 to avoid problems under brain-dead platforms like Digital UNIX (OSF1).
8744 [Ralf S. Engelschall] PR#2596
8746 *) mod_rewrite created RewriteLock files under the UID of the parent
8747 process, thus the child processes had no write access to the files.
8748 Now a chown() is done on the file to the uid of the children,
8749 if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341
8751 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
8752 TestCompile) instead of defining them manually in conf.h based on less
8753 accurate platform definitions. This way we no longer have to fiddle with
8754 OS-type and/or OS-version identifiers to discover whether a system header
8755 file exists or not. Instead we now directly check for the existence of
8756 those esoteric ones.

8760 *) mod_setenvif (BrowserMatch* and friends) will now match a missing
8761 field with "^$". [Ken Coar]
8763 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
8764 modules to load their own modules dynamically. This improves mod_perl
8765 and mod_php3 when these modules are loaded dynamically into Apache.
8768 *) Cache a proxied request in the event that the client cancels the
8769 transfer, provided that the configured percentage of the file has
8770 already been transfered. It works for HTTP transfers only. The
8771 new configuration directive is called CacheForceCompletion.

8779 Signals suck. [Dean Gaudet]
8781 *) suexec's error messages have been clarified a little bit. [Ken Coar]
8783 *) Clean up some, but perhaps not all, 8-bit character set problems
8784 with config file parsing, and URL parsing. We now define
8785 ap_isdigit(), ap_isupper(), ... which cast to an (unsigned char).
8786 This should work on most modern unixes.

8816 *) PORT: Add UnixWare 7 support
8817 [Vadim Kostoglodoff <vadim olly.ru>] PR#2463
8819 *) Fix the Guess-DSO-flags-from-Perl stuff in src/Configure: "perl" was
8820 used instead of "$PERL" which contains the correctly determined Perl
8821 interpreter (important for instance on systems where "perl" and "perl5"
8822 exists, like BSDI or FreeBSD, etc).
8823 [Ralf S. Engelschall] PR#2505
8825 *) Move the initial suEXEC-related startup message from plain
8826 fprintf()/stderr to a delayed ap_log_error()-based one to avoid problems
8827 when Apache is started from inetd (instead of standalone). Under this
8828 situation startup messages on stderr lead to problems (the line is sent
8829 to the client in front of the requested document).
8830 [Ralf S. Engelschall] PR#871, PR#1318
8832 *) Add a flag so ap_fnmatch() can be used for case-blind pattern matching.

8835 *) WIN32: Don't collapse multiple slashes in PATH_INFO.
8836 [Ben Laurie, Bill Stoddard <wgstodda us.ibm.com>] PR#2274
8838 *) WIN32 SECURITY: Eliminate trailing "."s in path components. These are
8839 ignored by the Windows filesystem, and so can be used to bypass security.
8840 [Ben Laurie, Alexei Kosut].
8842 *) We now attempt to dump core when we get SIGILL. [Jim Jagielski]
8844 *) PORT: remove broken test for MAP_FILE in http_main.c.
8845 [Wilfredo Sanchez <wsanchez apple.com>]
8847 *) PORT: Change support/apachectl to use "kill -0 $pid" to test if the
8848 httpd is running. This should be more portable than figuring out
8849 which of three dozen different versions of "ps" are installed.
8852 *) WIN32: If we can't figure out how to execute a file in a script
8853 directory, bail out of the request with an error message. [W G Stoddard]
8855 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
8856 these are treated by Win32 as if they are ".." but are not detected by
8857 other machinery within Apache. This is something of a kludge but
8858 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
8860 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
8861 pools and thus pollutes libap (until the pool stuff is moved there).
8864 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
8865 but case-insensitive platforms). New #define for this added to conf.h
8866 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455
8868 *) Enable DSO support for OpenBSD in general, not only for 2.x, because it
8869 also works for OpenBSD 1.x. [Ralf S. Engelschall]
8871 *) PORT: Fix compilation problem on ARM Linux.
8872 [Sam Kington <sam illuminated.co.uk>] PR#2443
8874 *) Let APACI's configure script determine some configuration parameters
8875 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
8876 remove some of the classical hurdles for new users when setting up
8877 Apache. This is done per default because it is useful for the average
8878 user. Package authors can use the --without-confadjust option to disable
8879 these configuration adjustments.
8880 [Ralf S. Engelschall]
8882 *) Added an EXTRA_DEPS configuration parameter which can be used
8883 to add an extra Makefile dependency for the httpd target, for instance
8884 to external third-party libraries, etc.
8885 [Ralf S. Engelschall]
8887 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
8888 as <IfModule>..</IfModule> sections) which can be used to skip or process
8889 contained commands dependend of ``-D PARAMETER'' options on the command
8890 line. This can be used to achieve logical conditions like <IfDefine
8891 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
8892 and thus especially can be used for conditionally loading DSO-based
8893 modules via LoadModule, etc. [Ralf S. Engelschall]
8895 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
8897 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
8899 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
8900 truncated which forced following HTTP headers to be data in the HTTP
8901 reponse. [Ralf S. Engelschall, Charles Fu <ccwf bacchus.com>]
8904 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
8905 in top-level configure script to avoid sed fails on some platforms (for
8906 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
8907 output of Awk. [Bill Houle <bhoule sandiegoca.ncr.com>] PR#2435
8909 *) Improve performance of directory listings (mod_autoindex) by comparing
8910 integer keys (last-modified and size) as integers rather than converting
8911 them to strings first. Also use a set of explicit byte tests rather
8912 than strcmp() to check for parent directory-ness of an entry. Oh, and
8913 make sure the parent directory (if displayed) is *always* listed first
8914 regardless of the sort key. Overall performance winnage should be good
8915 in CPU time, instruction cache, and memory usage, particularly for large
8916 directories. [Ken Coar]
8918 *) Add a tiny but useful goody to APACI's configure script: The generation
8919 of a config.status script (as GNU Autoconf does) which remembers the used
8920 configure command and hence can be used to restore the configuration by
8921 just re-running this script or for remembering the configuration between
8923 [Ralf S. Engelschall]
8925 *) Add httpd -t (test) option for running configuration syntax tests only.
8926 If something is broken it complains and exits with a return code
8927 non-equal to 0. This can be used manually by the user to check the Apache
8928 configuration after editing and is also automatically used by apachectl
8929 on (graceful) restart command to make sure Apache doesn't die on restarts
8930 because of a configuration which is now broken since the last (re)start.
8931 This way `apachectl restart' can be used inside cronjobs without having
8932 to expect Apache to be falling down. Additionally the httpd -t can be run
8933 via `apachectl configtest'.

8961 *) Add an additional "dummy" target to the "$(LIB)" target in generated

9071 ap_spawn_child_err became ap_spawn_child
9072 ap_spawn_child_err_buff became ap_bspawn_child
9073 spawn_child was obsoleted and moved to compat.h
9076 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
9077 programs: ap_spawn_child_err() is used and the Win32 case now uses
9078 CreateProcess() instead of a low-level execl() (which caused problems in
9079 the past under Win32).
9080 [Ralf S. Engelschall]
9082 *) A few cosmetics and trivial enhancements to APXS to make the
9083 generated Makefile more user friendly. [Ralf S. Engelschall]
9085 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
9086 was updated to use the normal apache error processing, thereby allowing
9087 proxy errors to be treated by ErrorDocument's as well. For this
9088 purpose, a new module-to-core communication variable "error-notes"
9089 was introduced; the proxy (and possibly other modules) communicates
9090 its error text using this variable. Its content is copied to a new
9091 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
9092 The old proxy special error routine ap_proxy_log_uerror()
9093 was replaced by regular ap_log_error() calls, many messages were made
9095 [Martin Kraemer] PR#494, 1259
9097 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
9100 *) Transform the configure message "You need root privileges for suEXEC"
9101 from a fatal error into a (more friendly) warning because the building
9102 ("make") of Apache we can allow, of course. Root privileges are needed
9103 only for the installation step ("make install"). So make sure the
9104 user is aware of this fact but let him proceed as long as he can.
9105 [Ralf S. Engelschall] PR#2288
9107 *) Renamed three more functions to common ap_ prefix which we missed at the
9108 Big Symbol Renaming because they're #defines and not real C functions:
9109 is_default_port(), default_port(), http_method().
9110 [Ralf S. Engelschall]
9112 *) A zero-length name after a $ in an SSI document should cause
9113 just the $ to be in the expansion. This was broken during the

9123 Changes with Apache 1.3b7
9125 *) Make sure a MIME-type can be forced via a RewriteRule even when no
9126 substitution takes place, for instance via the following rule:
9127 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often

9129 extension and outside any cgi-bin dirs to be executed as a CGI program.

9132 *) A fix for protocol issues surrounding 400, 408, and

9139 [Rick Ohnemus <rick ecompcon.com>]
9141 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
9142 logfile instead of fiddling around itself with child spawning stuff.

9145 *) Made RefererIgnore case-insensitive.
9147 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.

9151 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
9154 *) Improve RFC1413 support. [Bob Beck <beck bofh.ucs.ualberta.ca>]

9160 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
9161 [Ben Laurie] PR#2238
9163 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
9164 library), so CGI handling has been changed to use Win32 native handles
9165 instead of C file descriptors.
9166 [Ben Laurie and Bill Stoddard <wgstodda us.ibm.com>] PR#1129, 1607
9168 *) The proxy cache would store an incorrect content-length in the cached
9169 file copy after a cache update. That resulted in repeated fetching
9170 of the original copy instead of using the cached copy.
9171 [Ernst Kloppenburg <kloppen isr.uni-stuttgart.de>] PR#2094
9173 *) The Makefiles assumed that DSO files are build via $(LD). This
9174 is broken for two reasons: First we never defined at least LD=ld
9175 somewhere to make sure this works (it was silently assumed that most Make
9176 provide a built-in LD definition - ARGL!) and second using the generic LD
9177 variable is not the truth. Instead a special variable named LD_SHLIB is
9178 reasonable because although "ld" is usually the default, the command for
9179 building DSO files can be "libtool" or even "cc" on some systems.
9180 [Ralf S. Engelschall]
9182 *) Replace the AddVersionPlatform directive with ServerTokens which
9183 provides for more control over the format of the Server:
9184 header line. SERVER_SUBVERSION is no longer supported;
9185 all module should use the ap_add_version_component()
9186 API function instead. [Jim Jagielski]
9188 *) Support for the NCR MP/RAS 3.0
9189 [John Withers <withers semi.kcsc.mwr.irs.gov>]
9191 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
9192 not retrieved in src/Configure and thus was not useable.
9193 [Ralf S. Engelschall]
9195 *) Various Makefile consistency cleanups:
9196 - make OSDIR also automatically be relative to src/ like INCDIR
9197 - SUBDIRS is now generated in src/Makefile only and not in
9198 Makefile.config because it is a local define for this location.
9199 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
9200 any Makefile but make sure that at least the "-K inline" is kept in
9202 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
9203 - updated the dependencies theirself
9204 - removed not existing SHLIB variable from "clean" targets
9205 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
9206 already exists and OBJS_PIC are also just plain objects and have not
9207 directly to do with "shared" things. The only difference is that they
9208 contain PIC. So OBJS_PIC is the more canonical name.
9209 - Updated the Makefile-dependency lines for OBJS_PIC
9210 - Removed the Makefile-dependency line in Configure to avoid double
9212 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
9213 of xxx.lo as GNU libtool does with its PIC objects
9214 - reduce local complexity in modules Makefile.tmpl by moving the last
9215 existing target "depend" to the generation section in Configure, too.
9216 - removed the historical $(SPACER) which was used in the past together
9217 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
9218 is no longer needed.
9219 - force the build and run of the gen_xxx programs under main/ as the
9220 first step before building the objects because it looks cleaner
9221 [Ralf S. Engelschall]
9223 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
9226 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
9229 *) WIN32: Don't force ISAPI headers to finish with \n.
9230 [Jim Patterson <Jim.Patterson Cognos.COM>, Ben Laurie] PR#2060
9232 *) When opening "configuration" files (like httpd.conf, htaccess
9233 and htpasswd), Apache will not allow them to be non-/dev/null
9234 device files. This closes a DoS hole. At the same time,
9235 we use ap_pfopen to open these files to handle timeouts.
9236 [Jim Jagielski, Martin Kraemer]
9238 *) Apache will now log the reason its httpd children exit if they exit
9239 due to an unexpected signal. (It requires a new porting define,
9240 SYS_SIGLIST, which if defined should point to a list of text
9241 descriptions of the signals available. See PORTING.) [Dean Gaudet]
9243 *) WIN32: chdir() doesn't make sense in a multithreaded environment
9244 like WIN32. Before, Win32 CGI's could have had sporadic failures
9245 if a chdir call from one thread was made between another chdir call
9246 and a spawn in another thread. So, for now don't chdir for CGI scripts
9247 in WIN32. The current CGI "spec" is unclear as to whether it's
9248 necessary. Long-term fix is to either serialize the chdir/spawn combo
9249 or use WIN32 native calls to spawn a process. This temp fix was
9250 necessary to remove this as a showstopper for 1.3's release.
9253 *) Cleanup the suEXEC support in APACI and make it more safe:
9254 1. Add big fat hint in INSTALL about risks and to read the
9255 htdocs/manual/suexec.html document before using the suexec-related
9257 2. Make sure the user has at least provided one --suexec-xxxx option
9258 (specifies suEXEC parameters) in addition to --enable-suexec option.
9259 If only --enable-suexec is given APACI stops with a hint to INSTALL
9260 and htdocs/manual/suexec.html documents.
9261 3. Provide two additional --suexec-xxxx options to make the suEXEC
9262 configuration complete (especially for package maintainers who else
9263 had to patch the source tree) by providing ways to configure minimal
9264 UID/GID and safe PATH, too.
9265 [Ralf S. Engelschall]
9267 *) Cleanup of the `configure --shadow' process:
9268 - make sure the configure script creates its temporary files in the
9269 shadow tree to avoid conflicts with parallel configure runs
9270 - removed unnecessary option "-r" from "rm" call for Makefiles
9271 - make sure the configure scripts creates the shadow-wrapper Makefile
9272 only when no shadow trees already exists
9273 - make sure "make distclean" removes the shadow-wrapper Makefile but only
9274 when no more shadow trees exists
9275 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
9276 as fast (in the past it needed 70sec, now it runs just 38sec)
9277 - make sure CVS does not complain about the created files
9278 Makefille.<gnutriple> and directories src.<gnutriple>
9279 [Ralf S. Engelschall]
9281 *) Added the ap_add_version_component() API routine and the
9282 AddVersionPlatform core directive. The first allows modules to
9283 declare themselves in the Server response header field value,
9284 augmenting the SERVER_SUBVERSION define in the Configuration file
9285 with run-time settings (more useful in a loadable-module environment).
9286 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
9287 into the server version string. [Ken Coar] PR#2056
9289 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
9292 *) Emit the "Accept-Range" header for the default handler.
9293 [Brian Behlendorf] PR#1464
9295 *) Add a note to httpd.conf-dist that apache will on some systems fail
9296 to start when the Group # is set to a negative or large positive value.
9299 *) Make sure the module execution order is correct even when some modules
9300 are loaded under runtime (`LoadModule') via the DSO mechanism:
9301 1. The list of loaded modules is now a dynamically allocated one
9302 and not the original statically list from modules.c
9303 2. The loaded modules are now correctly setup by LoadModule for
9304 later use by the AddModule command.
9305 3. When the DSO mechanism for modules is used APACI's `install'
9306 target now enables all created `LoadModule' lines per default because
9307 this is both already expected by the user _and_ needed to avoid
9308 confusion with the next point and reduces the Makefile.tmpl complexity
9309 4. When the DSO mechanism for modules is used, APACI's `install'
9310 target now additionally makes sure the module list is reconstructed
9311 via a complete `ClearModuleList+AddModule...' entry.
9312 5. The support tool `apxs' now also makes sure an AddModule command
9313 is added in addition to the LoadModule command.
9314 6. The modules.c generation was extended to now contain two
9315 comments to make sure no one is confused by the confusing terminology
9316 of loading/linking (we use load=link+load & link=activate instead of
9317 the obvious load=activate & link=link :-( )
9318 This way now there is no longer a difference under execution time between
9319 statically and dynamically linked modules.

9323 Big Symbol Renaming. [Ralf S. Engelschall]
9325 *) Add a comment to mod_example.c showing the format of a FLAG command
9328 *) Standardized the time format in mod_status to match that of other
9329 places in the code (e.g. DATE_GMT). PR#1551
9331 *) Fix handling of %Z in timefmt strings for those platforms with no time
9332 zone information in their tm struct. [Paul Eggert <eggert twinsun.com>]
9335 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
9336 feature compatible with 'UseCanonicalName off' by changing
9337 r->server->server_hostname to ap_get_server_name(). And I changed some
9338 functions which use r->server->port to use ap_get_server_port() instead,
9339 because if there's no Port directive in the config r->server->port is 0.
9342 *) get/set_module_config are trivial enough to be better off inline. Worth
9343 1.5% performance boost. [Dean Gaudet]

9346 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
9349 *) [BS2000 security] BS2000 needs an extra authentication to initialize
9350 the task environment to the unprivileged User id. Otherwise CGI scripts
9351 would have a way to gain super user access. [Martin Kraemer]

9357 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
9358 the encoding type from the Accept-Encoding header (if it's there)

9373 of APEXIT_CHILDFATAL) the parent process to abort and
9374 shutdown the server if the error in the child process was
9375 fatal enough. [Jim Jagielski]

9389 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
9390 Additionally the checks for finding the vendor DSO library were moved
9391 from mod_so.c to Configure because first it needs $PLAT etc. and second
9392 mod_so already uses an abstraction layer and does not fiddle with the
9393 vendor functions itself.
9394 [Jens-Uwe Mager, Ralf S. Engelschall]
9396 *) PORT: Some optimization defines for NetBSD
9397 [Jaromir Dolecek <dolecek ics.muni.cz>] PR#2165
9399 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
9400 [Jaromir Dolecek <dolecek ics.muni.cz>, Ralf S. Engelschall] PR#2158
9402 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
9403 AIX variants should work fine, too. Even AIX 3.x should work). This is
9404 accomplished by using the free DSO emulation code from Jens-Uwe Mager
9405 which we put into a os/unix/os-dso-aix.c file.
9406 [Ralf S. Engelschall]
9408 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
9409 that we should use NET_SIZE_T == int but the include files force size_t.
9410 [Ralf S. Engelschall]
9412 *) Fix two bugs in select() handling in http_main.c.
9415 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
9416 is unset (as it is in situations like timeouts) where it is unclear
9417 whether errno is set or not. [Martin Kraemer]
9419 *) Just having APACI's localstatedir is too general and not enough for most
9420 of the systems. 1.3b6 again required manual APACI patches by package
9421 maintainers from Red Hat and FreeBSD because for their filesystem layout a
9422 little bit more flexibility in configuring the paths is needed. Hence we
9423 provide three additional configure options (--runtimedir, --logfiledir,
9424 --proxycachedir) which now can be used for more granular adjustments if
9425 --localstatedir is not enough to fit the particular needs. As a nice
9426 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
9427 [Ralf S. Engelschall]
9429 *) Make the install root for "make install" in APACI's Makefile overrideable
9430 by package authors. This way we are even more friendly to package
9431 maintainers (especially Debian and Red Hat) who build for the real prefix
9432 via "configure --prefix=/<real>" but use a different local prefix via
9433 "make root=/tmp/apache install" for rolling the package without bristling
9434 the target location on their system.
9435 [Ralf S. Engelschall]
9437 *) Workaround sed limitations in APACI's configure script by now
9438 substituting in chunks of 50 commands (because for instance HPUX's vendor
9439 sed has a limit of max. 98 commands)
9440 [Ralf S. Engelschall] PR#2136
9442 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
9443 [Ralf S. Engelschall] PR#2140
9445 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
9446 RENAMING process because they are defined as pre-processor macros instead
9447 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
9448 [Ralf S. Engelschall]
9450 *) Workaround braindead AWK's when generating ap_config.h: The split() and
9451 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
9452 [Ralf S. Engelschall] PR#2139
9454 *) Various bugfixes and cleanups for the APACI configure script:
9455 o fix IFS handling for _nested_ situation
9456 o fix Perl interpreter search: take first one found instead of last one
9457 o fix DSO consistency check
9458 o print error messages to stderr instead of stdout
9459 o add install-quiet for --shadow situation to Makefile stub
9460 o reduce complexity by avoiding sed-hacks for rule and module list loops

9463 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
9465 *) Make sure the input field separator (IFS) shell variable is explicitly
9466 initialized correctly before _every_ `for' loop and also restored after
9467 the loops. [Ralf S. Engelschall]
9469 *) Make sure that "make install" doesn't overwrite the `mime.types' and
9470 `magic' files from an existing Apache installation. Because people often
9471 customize these for own MIME and content types.

9478 [Ralf S. Engelschall] PR#2105
9480 *) Let "configure" clear out the users parameters (provided as shell

9482 exported them (which is not needed, but some users do it).
9483 [Ralf S. Engelschall] PR#2101
9485 *) Provide backward compatibility from some old src/Configuration.tmpl
9486 parameter names to the canonical Autoconf-style shell variable names. For

9509 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick colby.edu>]
9511 *) If you start apache with the -S command line option it will dump
9512 out the parsed vhost settings. This is useful for folks trying
9513 to figure out what is wrong with their vhost configuration.
9514 (Other dumps may be added in the future.) [Dean Gaudet]
9516 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
9517 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
9520 *) Because /usr/local/apache is the default prefix the ``configure
9521 --compat'' option no longer has to set prefix, again. This way the
9522 --compat option honors a leading --prefix option. [Lars Eilebrecht]
9524 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
9525 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
9526 to avoid "discard const" warnings. [Ralf S. Engelschall]
9528 *) If a specific handler is set for a file yet the request still
9529 ends up being handled by the default handler, log an error
9530 message before handling it. This catches things such as trying
9531 to use SSIs without mod_include enabled. [Marc Slemko]
9533 *) Fix error logging for the startup case where ap_log_error() still uses
9534 stderr as the target. Now the default log level is honored here, too.
9535 [Ralf S. Engelschall]
9537 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
9538 long" errors when generating the MODULES entry for src/Makefile

9541 *) Make sure src/Configure doesn't complain about the old directory
9542 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
9544 Changes with Apache 1.3b6
9546 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
9548 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
9549 interface via the similar but proprietary HP/UX shl_xxx-style system
9550 calls. [Ralf S. Engelschall]
9552 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
9553 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
9554 Make. [Ralf S. Engelschall]
9556 *) ++++ THE BIG SYMBOL RENAMING ++++
9557 To avoid symbol clashes with third-party code compiled into the server,
9558 we globally applied the prefix "ap_" to the following classes of
9560 - Apache provided general functions (e.g., ap_cpystrn)
9561 - Public API functions (e.g., palloc, bgets)
9562 - Private functions which we can't make static (because of
9563 cross-object usage) but should be (e.g., new_connection)
9564 For backward source compatibility a new header file named compat.h was
9565 created which provides defines for the old symbol names and can be used
9566 by third-party module authors.
9569 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
9570 problem under SVR4 is that there is no command flag to force the linker
9571 to export the global symbols of the httpd executable therewith they are
9572 available to the DSO's. Instead of problematic hacks like creating a
9573 dummy.so file (containing dummy references to all global symbols) the
9574 httpd binary is linked against, we use a clean trick stolen from Perl 5:
9575 Placing the Apache core code itself into a DSO library named libhttpd.so.
9576 This way the global symbols _HAVE_ to be exported and thus are available
9577 to any manually loaded DSO's under runtime. To reduce the impact to the
9578 user to null we go even further and create a stub httpd executable which
9579 automatically keeps track of the DSO library loading itself and thus
9580 hides the complete mechanism from the user. Although the generation of
9581 this DSO library is automatically triggered for platforms which
9582 essentially need it (mostly all SVR4-derivates) it can be also enabled
9583 manually via the Rule SHARED_CORE. This can be interesting in the future
9584 where we perhaps exploit this libhttpd.so mechanism for providing nifty
9585 features like graceful upgrades, or whatever.
9586 [Ralf S. Engelschall, Martin Kraemer]
9588 *) Build the libraries before building the rest of the tools. [Ben Hyde]
9590 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
9591 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
9592 conventions while "clean" removes only stuff created by "all" targets,
9593 "distclean" additionally removes the stuff from the configuration
9594 process. This way "make distclean" (hence the name) provides a fresh
9595 source tree as it was for distribution.
9596 [Ralf S. Engelschall]
9598 *) Allow top-level (APACI) Makefile to break on build errors
9599 the same way the src/ subtree Makefiles breaks on them by replacing the
9600 initial APACI sed-subdir-display-kludge with a more clean
9601 variable-passing-solution: variable SDP can optionally hold the subdir
9602 prefix which is consistently used for displaying the subdir movement.
9603 This way even the top-level Makefile can stop correctly on errors as the
9604 user expects. [Ralf S. Engelschall]
9606 *) Fixed ordering of argument checks for RewriteBase directive.
9607 [Todd Eigenschink <eigenstr mixi.net>] PR#2045
9609 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
9610 indicating that a module is being compiled for dynamic loading. Also
9611 remove #define IS_MODULE from modules and add SHARED_MODULE define
9612 to the mak/dsp files. [Alexei Kosut]
9614 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
9615 since we are now logging APLOG_WARNING by default. [Roy Fielding]
9617 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
9619 *) Add documentation file and src/Configuration.tmpl entry for the
9620 experimental mod_mmap_static module. Because although it is and marked as
9621 an experimental one it is distributed and thus should be documented and
9622 prepared for configuration the same way as all others modules.
9623 [Ralf S. Engelschall]
9625 *) Add query (-q) option to apxs support tool to be able to manually query
9626 specific settings from apxs. This is needed for instance when you
9627 manually want to access Apache's header files and you need to assemble
9628 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
9629 [Ralf S. Engelschall]
9631 *) Now src/Configure uses a fallback strategy for the shared object support
9632 on platforms where no explicit information is available: If a Perl
9633 installation exists we ask it about its shared object support and if it's
9634 the dlopen-style one we shamelessly guess the compiler and linker flags
9635 for creating shared objects from Perls knowledge. Of course, the user is
9636 warning about what we are doing and informed that he should send us
9637 the guessed flags when they work. [Ralf S. Engelschall]
9639 *) Provide APACI --without-support option to be able to disable the build
9640 and installation of the support tools from the src/support/ area.
9641 Although its useful to have these installed per default we should provide
9642 a way to compile and install without them for backward-compatibility.
9643 [Ralf S. Engelschall]
9645 *) Add of the new APache eXtenSion (apxs) support tool for building and
9646 installing modules into an _already installed_ Apache package through the
9647 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
9648 this approach actually doesn't need the Apache source tree. The
9649 (APACI-installed) server package is enough, because this now includes the
9650 Apache C header files (PREFIX/include) and the new APXS tool
9651 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
9652 module authors to build their Apache modules _OUTSIDE_ the Apache source
9653 tree while avoiding them to fiddle around with the totally platform
9654 dependend way of compiling DSO files. The tool supports all ranges of
9655 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
9656 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
9657 on-the-fly generate a minimalistic Makefile and sample module for the
9658 first step to provide both a quick success event and to demonstrate the
9659 APXS mechanism to module authors. [Ralf S. Engelschall]
9661 *) Fix core dumps in use of CONNECT in proxy.
9662 [<Rainer.Scherg rexroth.de>] PR#1326, #1573, #1942
9664 *) Modify the log directives in httpd.conf-dist files to use CustomLog
9665 so that users have examples of how CustomLog can be used.
9668 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
9669 the Apache distribution tree. Until Apache 1.3 there was no real
9670 out-of-the-box batch-capable build and installation procedure for the
9671 complete Apache package. This is now provided by a top-level "configure"
9672 script and a corresponding top-level "Makefile.tmpl" file. The goal is
9673 to provide a GNU Autoconf-style frontend which is capable to both drive
9674 the old src/Configure stuff in batch and additionally installs the
9675 package with a GNU-conforming directory layout. Any options from the old
9676 configuration scheme are available plus a lot of new options for flexibly
9677 customizing Apache. [Ralf S. Engelschall]
9679 *) The floating point ap_snprintf code wasn't threadsafe.
9680 Had to remove the HAVE_CVT macro in order to do threadsafe
9681 calling of the ?cvt() floating point routines. [Dean Gaudet]
9683 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
9685 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
9686 [Jim Jagielski] PR#1901
9688 *) BUG: Configure was using TCC and CC inconsistently. Make sure
9689 Configure knows which CC we are using. [Jim Jagielski]
9691 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
9692 was defined in a parent directory. [Lars Eilebrecht]
9694 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
9695 a generic printf-style routine that can call arbitrary output
9696 routines. Use this to replace http_bprintf.c. Add new routines
9697 psprintf(), pvsprintf() which allocate the exact amount of memory
9698 required for a string from a pool. Use psprintf() to clean up
9699 various bits of code which used ap_snprintf()/pstrdup().
9702 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
9703 ap_snprintf() has different semantics and formatting codes than
9704 snprintf(). [Dean Gaudet]
9706 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
9707 is necessary on at least Solaris where the /etc/rc?.d scripts
9708 are run with these signals ignored, and "SIG_IGN" settings are
9709 maintained across exec().

9735 [Jürgen Keil <jk tools.de>] PR#2000
9737 *) Allow %2F in two situations: 1) it is in the query part of the URI,
9738 therefore not exposed to %2F -> '/' translations and 2) the request
9739 is a proxy request, so we're not dealing with a local resource anyway.
9740 Without this, the proxy would fail to work for any URL's with
9741 %2f in them (occurs quite often in
9742 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
9744 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
9746 *) Make the shared object compilation command more portable by avoiding
9747 the direct combination of `-c' & `-o' which is not honored by some
9748 compilers like UnixWare's cc. [Ralf S. Engelschall]
9750 *) WIN32: the proxy was creating filenames missing the last four

9759 *) Reanimated the (still undocumented) proxy receive buffer size directive:
9760 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
9761 name was really too generic, added documentation for this directive to
9762 the mod_proxy.html and corrected the hyperlink to it in the

9768 *) Make Configure die when you give it an unknown command switch.
9771 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
9772 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
9773 and per default compiled support programs have manual pages - just to
9774 document our stuff a little bit more and to be able to do really
9775 Unix-like installations ;-) [Ralf S. Engelschall]
9777 *) Major cleanups to the Configure script to make it and its generated
9778 Makefiles again readable and maintainable: add SRCDIR option, removed
9779 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
9780 generated sections, consequently added Makefile headers with inheritance
9781 information, added subdir movement messages for easier following where
9782 the build process currently stays (more verbose then standard Make, less
9783 verbose than GNU make), same style to comments in the Configure script,
9784 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
9786 *) Add the new ApacheBench program "ab" to src/support/: This is derived
9787 from the ZeusBench benchmarking program and can be used to determine the

9791 [Ralf S. Engelschall]
9793 *) API: Various core functions that are definately not part of the API
9794 have been made static, and a few have been marked API_EXPORT. Still
9795 more have been marked CORE_EXPORT and are not intended for general
9796 use by modules. [Doug MacEachern, Dean Gaudet]
9798 *) mod_proxy was not clearing the Proxy-Connection header from
9799 requests; now it does. This did not violate any spec, however
9800 causes poor interactions when you are talking to remote proxies.
9801 [Marc Slemko] PR#1741
9803 *) Various cleanups to the command line interface and manual pages.
9804 [Ralf S. Engelschall]
9806 *) cfg_getline() was not properly handling lines that did not end
9807 with a line termination character. [Marc Slemko] PR#1869, 1909
9809 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
9811 *) Clean up some undocumented behavior of mod_setenvif related to
9812 "merging" two SetEnvIf directives when they match the same header
9813 and regex. Document that mod_setenvif will perform comparisons in
9814 the order they appear in the config file. Optimize mod_setenvif by
9815 doing more work at config time rather than at runtime.
9818 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
9819 to allow for modules to overrule them and to reduce redefinition
9820 warnings [Jim Jagielski]
9822 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
9825 *) Making the hard-coded cross-module function call mime_find_ct() (from
9826 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
9827 checking is really called even for proxy requests except for URLs with
9828 HTTP schemes (because there we can optimize by not running the type
9829 checking hooks due to the fact that the proxy gets the MIME Content-type
9830 from the remote host later). This change cleans up mod_mime by removing
9831 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
9832 especially unbundles mod_proxy and mod_mime. This way they both now can
9833 be compiled as shared objects and are no longer tied together.
9834 [Ralf S. Engelschall]
9836 *) util.c cleanup and speedup. [Dean Gaudet]
9838 *) API: Clarification, pstrndup() will always copy n bytes of the source
9839 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
9841 *) Mark module command_rec and handler_rec structures const so that they
9842 end up in the read-only data section (and are friendlier to systems
9843 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
9845 *) Add check to the "Port" directive to make sure the specified
9846 port is in the appropriate range. [Ben Hyde]
9848 *) Performance improvements to invoke_handler().
9849 [Dmitry Khrustalev <dima bog.msu.su>]
9851 *) Added support for building shared objects even for library-style modules
9852 (which are built from more than one object file). This now provides the
9853 ability to build mod_proxy as a shared object module. Additionally
9854 modules like mod_example are now also supported for shared object
9855 building because the generated Makefiles now no longer assume there is at
9856 least one statically linked module. [Ralf S. Engelschall]
9858 *) API: Clarify usage of content_type, handler, content_encoding,
9859 content_language and content_languages fields in request_rec. They
9860 must always be lowercased; and the strings pointed to shouldn't
9861 be modified (you must copy them to modify them). Fix a few bugs
9862 related to this. [Dean Gaudet]
9864 *) API: Clarification: except for RAW_ARGS, all command handlers can
9865 treat the char * parameters as permanent, and modifiable. There
9866 is no need to pstrdup() them. Clean up some needless pstrdup().
9869 *) Now mod_so keeps track of which module shared objects with which names
9870 are loaded and thus avoids multiple loading and unloading and irritating
9871 error_log messages. [Ralf S. Engelschall]
9873 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
9874 environment variable in the apache core. But that tweaking interferes
9875 with mod_setenv. So don't tweak if the user has specified an explicit
9876 TZ variable. [Jay Soffian <jay cimedia.com>] PR#1888
9878 *) rputs() did not calculate r->sent_bodyct properly.
9879 [Siegmund Stirnweiss <siegst kat.ina.de>] PR#1900
9881 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
9882 name, or left unset if this value is unavailable. Apache was setting
9883 it to the IP address when unavailable.
9884 [Tony Finch <fanf demon.net>] PR#1925
9886 *) Various improvements to the configuration and build support for compiling
9887 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
9888 OSF1 support with GCC and vendor compilers was added. This way shared
9889 object support is now provided out-of-the-box for FreeBSD, Linux,
9890 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
9891 [Ralf S. Engelschall]
9893 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
9894 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
9895 and USE_OS2_SCOREBOARD. [Dean Gaudet]
9897 *) Fix one more special locking problem for RewriteMap programs in
9898 mod_rewrite: According to the documentation of flock(), "Locks are on
9899 files, not file descriptors. That is, file descriptors duplicated
9900 through dup(2) or fork(2) do not result in multiple instances of a lock,
9901 but rather multiple references to a single lock. If a process holding a
9902 lock on a file forks and the child explicitly unlocks the file, the
9903 parent will lose its lock.". To overcome this we have to make sure the
9904 RewriteLock file is opened _AFTER_ the childs were spawned which is now
9905 the case by opening it in the child_init instead of the module_init API
9906 hook. [Ralf S. Engelschall] PR#1029
9908 *) Change to Location and LocationMatch semantics. LocationMatch no
9909 longer lets a single slash match multiple adjacent slashes in the
9910 URL. This change is for consistency with RewriteRule and
9911 AliasMatch. Multiple slashes have meaning in URLs that they do
9912 not have in (some) filesystems. Location on the other hand can
9913 be considered a shorthand for a more complicated regex, and it
9914 does match multiple slashes with a single slash -- which is
9915 also consistent with the Alias directive.
9916 [Dean Gaudet] related PR#1440
9918 *) Fix bug with mod_mime_magic causing certain files, including files
9919 of length 0, to result in no response from the server.
9922 *) The Configure script now generates src/include/ap_config.h which
9923 contains the set of defines used when Apache is compiled on a platform.
9924 This file can then be included by external modules before including
9925 any Apache header files in case they are being built separately from
9926 Apache. Along with this change, a couple of minor changes were
9927 made to make Apache's #defines coexist peacefully with any autoconf
9928 defines an external module might have. [Rasmus Lerdorf]
9930 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
9931 but without any RewriteXXXXX directives. Here mod_rewrite is given no
9932 chance by the API to initialize its per-server configuration and thus
9933 receives the wrong one from the main server. This is now avoided by
9934 remembering the server together with the config structure while
9935 configuring and later assuming there is no config when we see a
9936 difference between the remembered server and the one calling us.
9937 [Ralf S. Engelschall] PR#1790
9939 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
9940 is automatically disabled under configure time when the dbm_xxx functions
9941 are not available. Second, two heavy source code errors in the DBM
9942 support code were fixed. This makes DBM RewriteMap's usable again after
9943 a long time of brokenness. [Ralf S. Engelschall] PR#1696
9945 *) Now all configuration files support Unix-style line-continuation via
9946 the trailing backslash ("\") character. This enables us to write down
9947 complex or just very long directives in a more readable way. The
9948 backslash character has to be really the last character before the
9949 newline and it has not been prefixed by another (escaping) backslash.
9950 [Ralf S. Engelschall]
9952 *) When using ProxyPass the ?querystring was not passed correctly.
9953 [Joel Truher <truher wired.com>]
9955 *) To deal with modules being compiled and [dynamically] linked
9956 at a different time from the core, the SERVER_VERSION and
9957 SERVER_BUILT symbols have been abstracted through the new
9958 API routines apapi_get_server_version() and apapi_get_server_built().
9961 *) WIN32: Preserve trailing slash in canonical path (and hence
9962 in PATH_INFO). [Paul Sutton, Ben Laurie]
9964 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
9965 depending on the rev of Solaris and what mixture of modules
9966 are in use. So it has been disabled, and Solaris is back to
9967 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
9968 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
9969 up static content only servers. Or it may fail unpredictably.
9970 [Dean Gaudet] PR#1779, 1854, 1904
9972 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
9975 *) API: Rewrite of absoluteURI handling, and in particular how
9976 absoluteURIs match vhosts. Unless a request is a proxy request, a
9977 "http://host" url is treated as if a similar "Host:" header had been
9978 supplied. This change was made to support future HTTP/1.x protocols
9979 which may require clients to send absoluteURIs for all requests.
9981 In order to achieve this change subtle changes were made to the API. In a
9982 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
9983 that the unmodified uri can be retrieved easily. r->proxyreq is not set
9984 by the core, modules must set it during the post_read_request or
9985 translate_names phase.
9987 Plus changes to the virtualhost test suite for absoluteURI testing.
9989 This fixes several bugs with the proxy proxying requests to vhosts
9990 managed by the same httpd.
9993 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
9994 code from mod_rewrite. The vhost matching is now performed by a
9995 globally available function matches_request_vhost(). [Dean Gaudet]
9997 *) Reduce memory usage, and speed up ServerAlias support. As a
9998 side-effect users can list multiple ServerAlias directives
9999 and they're all considered.

10002 *) The "poly" directive in image maps did not include the borders of the
10003 polygon, whereas the "rect" directive does. Fix this inconsistency.
10004 [Konstantin Morshnev <moko design.ru>] PR#1771
10006 *) Make \\ behave as expected. [<Ronald.Tschalaer psi.ch>]
10008 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
10009 address. [Todd Eigenschink <eigenstr mixi.net>] PR#1885
10011 *) API: A new source module main/util_uri.c; It contains a routine
10012 parse_uri_components() and friends which breaks a URI into its component
10013 parts. These parts are stored in a uri_components structure called
10014 parsed_uri within each request_rec, and are available to all modules.
10015 Additionally, an unparse routine is supplied which re-assembles the URI
10016 components back to an URI, optionally hiding the username:password@ part
10017 from ftp proxy requests, and other useful routines. Within the structure,
10018 you find on a ready-for-use basis:
10019 scheme; /* scheme ("http"/"ftp"/...) */
10020 hostinfo; /* combined [user[:password]@]host[:port] */
10021 user; /* user name, as in http://user:passwd@host:port/ */
10022 password; /* password, as in http://user:passwd@host:port/ */
10023 hostname; /* hostname from URI (or from Host: header) */
10024 port_str; /* port string (integer representation is in "port") */
10025 path; /* the request path (or "/" if only scheme://host was given) */
10026 query; /* Everything after a '?' in the path, if present */
10027 fragment; /* Trailing "#fragment" string, if present */
10028 This is meant to serve as the platform for *BIG* savings in
10029 code complexity for the proxy module (and maybe the vhost logic).
10032 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
10033 ${map:key}) available for all location where a string is created in
10034 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
10035 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
10036 possible expansions are consequently usable at all string creation
10037 locations. [Ralf S. Engelschall]
10039 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
10040 and not 1) and the per-virtual-server merging of directives. Now all
10041 directives except `RewriteEngine' and `RewriteOption' are either
10042 completely overridden (default) or completely inherited (when
10043 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
10045 *) Fix `RewriteMap' program lookup in situations where such maps are
10046 defined but disabled (`RewriteEngine off') in per-server context.
10047 [Ralf S. Engelschall] PR#1431
10049 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
10050 server to bind to port 0 rather than 80. [Dean Gaudet]
10052 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
10053 (like SunOS and FreeBSD) which don't accept the locking of pipes
10054 directly. A new directive RewriteLock is introduced which can be used to
10055 setup a separate locking file which then is used for synchronization.
10056 [Ralf S. Engelschall] PR#1029
10058 *) WIN32: The server root is obtained from the registry key
10059 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently
10060 "1.3 beta"), unless overridden by the -d command line flag. The
10061 value is stored by running "apache -i -d serverroot". [Paul Sutton]
10063 *) Merged os/win32/mod_dll.c into modules/standard/mod_so.c to support
10064 dynamic loading on Win32 and Unix via the same module. [Paul Sutton]
10066 *) Now mod_rewrite no longer makes problematic assumptions on the characters
10067 a username can contain when trying to expand it via /etc/passwd.
10068 [Ralf S. Engelschall]
10070 *) The mod_setenvif BrowserMatch backwards compatibility command did not
10071 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
10073 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
10074 type but with a special post-processing for the looked-up value: It
10075 parses it into alternatives according to `|' chars and then only one
10076 particular alternative is chosen randomly (this is an essential
10077 functionality needed for balancing between backend-servers when using
10078 Apache as a Reverse Proxy. The looked up value here is a list of
10079 servers). Second, `int' with the built-in maps named `tolower' and
10080 `toupper' which can be used to map URL parts to a fixed case (this is an
10081 essential feature to fix the case of server names when doing mass
10082 virtual-hosting with the help of mod_rewrite instead of using
10083 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
10084 Jay Soffian <jay cimedia.com>] PR#1631
10086 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
10087 This directive lets Apache adjust the URL in Location-headers on HTTP
10088 redirect responses sent by the remote server. This way the virtually
10089 mapped area is no longer left on redirects and thus by-passed which is
10090 especially essential when running Apache as a reverse proxy.

10093 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
10094 hidden. [Alvaro Martinez Echevarria]
10096 *) Apache will, when started with the -X (single process) debugging flag,
10097 honor the SIGINT or SIGQUIT signals again now. This capability got lost
10098 a while ago during OS/2 signal handling changes.

10101 m68k chips in mod_status [Scott Anguish and Timothy Luoma

10108 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
10109 In particular the handlers could trigger themselves into an infinite
10110 loop if RLimitMem was used with a small amount of memory -- too small
10111 for the signal stack frame to be set up. [Dean Gaudet]

10125 *) mod_info would occasionally produce an unpaired <tt> in its
10126 output. Fixed. [Martin Kraemer]
10128 *) By default AIX binds a process (and it's children) to a single
10129 processor. httpd children now unbind themselves from that cpu
10130 and re-bind to one selected at random via bindprocessor()
10133 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
10134 effect. Work around it by using RLIMIT_AS for the RLimitMEM
10135 directive. [Enrik Berkhan <enrik inka.de>] PR#1816

10201 *) MiNT port update. [Jan Paul Schmidt]
10203 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
10204 equivalent, similarly for x-compress and compress. Apache
10205 now ignores a leading x- when comparing encodings. It also
10206 preserves the encoding the client requests (for example if
10207 it requests x-gzip, then Apache will respond with x-gzip
10208 in the Content-Encoding header).

10238 *) Yet another rearrangement of the source tree.. now all the common
10239 header files are in the src/include directory. The -Imain -Iap
10240 references in Makefiles have been changed to the simpler -Iinclude
10241 instead. In addition to simplifying the build a little bit, this
10242 also makes it clear when a module is referencing something in a
10243 other than kosher manner (e.g., the proxy including mod_mime.h).
10244 Module-private header files (the proxy, mod_mime, the regex library,
10245 and mod_rewrite) have not been moved to src/include; nor have
10246 the OS-abstraction files. [Ken Coar]

10280 of the key and value. But in many cases this is not required
10281 because the key/value is a constant, or the value has been built
10282 by pstrcat() or other similar means. New routines table_addn,
10283 table_mergen, and table_setn have been added to the API, these
10284 routines do not pstrdup() their arguments. The core code and
10285 standard modules were changed to take advantage of these routines.
10286 The resulting server is up to 20% faster in some situations.
10288 Note that it is easy to get code subtly wrong if you pass a key/value
10289 which is in a pool other than the pool of the table. The only
10290 safe thing to do is to pass key/values which are in the pool of
10291 the table, or in one of the ancestors of the pool of the table.
10292 i.e. if the table is part of a subrequest, a value from the main
10293 request's pool is OK since the subrequest pool is a sub_pool of the
10294 main request's pool (and therefore has a lifespan at most as long as
10295 the main pool). There is debugging code which can detect improper
10296 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.

10299 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"

10301 Update documentation to reflect the code -- if there's no
10302 MimeMagicFile directive then the module is not enabled.
10305 *) PORT: Some older *nix dialects cannot automatically start scripts
10306 which begin with a #! interpreter line (the shell starts the scripts
10307 appropriately on these platforms). Apache now supports starting of

10309 [Martin Kraemer, with code from Peter Wemm <peter zeus.dialix.oz.au>
10312 *) API: "typedef array_header table" removed from alloc.h, folks should
10313 have been writing to use table as if it were an opaque type, but even
10314 some standard modules got this wrong. By changing the definition
10315 to "typedef struct table table" module authors will receive compile
10316 time warnings that they're doing the wrong thing. This change
10317 facilitates future changes with more sophisticated table
10318 structures. Specifically, module authors should be using table_elts()
10319 to get access to an array_header * for the table. [Dean Gaudet]
10321 *) API: Renamed new_connection() to avoid namespace collision with LDAP
10322 library routines. [Ken Coar, Rasmus Lerdorf]
10324 *) WIN32: mod_speling is now available on the Win32 platform.
10327 *) For clarity the following compile time definition was changed:
10329 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
10331 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
10332 and not be a general notice that the OS has mmap(). Now the
10333 HAVE_MMAP/SHMGET #defines strictly are informational that the
10334 OS has that method of shared memory; the type to use for
10335 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
10336 and USE_SHMGET_SCOREBOARD). This allows outside modules to
10337 determine if shared memory is available and allows Apache
10338 to determine the best method to use for the scoreboard.

10783 something which is not a FILE* [Martin Kraemer]
10785 *) Make single-exe Windows install. [Ben Laurie and Eric Esselink]
10787 *) WIN32: Make CGI work under Win95. [Ben Laurie and Paul Sutton]
10789 *) WIN32: Make index.html and friends work under Win95. [Ben Laurie]
10791 *) PORT: Solaris 2.4 needs Spencer regex, the system regex is broken.

10808 __NetBSD__. Workaround by defining NETBSD.
10809 [Chris Craft <ccraft cncc.cc.co.us>] PR#977
10811 *) PORT: UnixWare 2.x requires -lgen for syslog.

10818 ["Pavel Yakovlev (Paul McHacker)" <hac tomcat.olly.ru>]
10820 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
10821 use USE_SHMGET_SCOREBOARD.
10824 *) Various improvements in detecting config file errors (missing closing
10825 directives for <Directory>, <Files> etc. blocks, prohibiting global
10826 server settings in <VirtualHost> blocks, flagging unhandled multiple
10827 arguments to <Directory>, <Files> etc.)
10830 *) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
10831 variable to provide this one to suexec'd CGIs, too.
10832 [M.D.Parker <mdpc netcom.com>] PR#1284
10834 *) New support tool: src/support/split-logfile, a sample Perl script which
10835 splits up a combined access log into separate files based on the
10836 name of the virtual host (listed first in the log records by "%v").
10839 Changes with Apache 1.3b2 (there is no 1.3b1)
10841 *) TestCompile was not passing $LIBS [Dean Gaudet]
10843 *) Makefile.tmpl was not using $CFLAGS in the link phase.
10846 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
10847 rudimentary memory debugger which can be used on live servers with
10848 low impact -- it sets all allocated and freed memory bytes to 0xa5.
10849 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
10850 and free() for each object. This is far more expensive and should
10851 only be used for testing with tools such as Electric Fence and
10852 Purify. See main/alloc.c for more details. [Dean Gaudet]
10854 *) Configure uses a sh trap and didn't set its exitcode properly.
10855 [Dean Gaudet] PR#1159
10857 *) Yet another vhost revamp. Add the NameVirtualHost directive which
10858 explicitly lists the ip:port pairs that are to be used for name-vhosts.
10859 From a given ip:port, regardless what the Host: header is, you can
10860 only reach the vhosts defined on that ip:port. The precedence of
10861 vhosts was reversed to match other precedences in the config --
10862 the earlier vhosts override the later vhosts. All vhost matching was
10863 moved into http_vhost.[ch]. [Dean Gaudet]
10865 *) ap_inline can be used to force inlining. GNUC __attribute__() can
10866 be used for whatever reason is appropriate (i.e. format() warnings
10867 for printf style functions). Both are enabled only with
10868 gcc >= 2.7.x (so that we have fewer support issues with older
10869 versions). [Dean Gaudet]
10871 *) Fix support for Proxy Authentication (we were testing the response
10872 status too early). [Marc Slemko]
10874 *) CoreDumpDirectory directive directs where the core file is
10875 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
10876 received. [Marc Slemko, Dean Gaudet]
10878 *) PORT: Support for Atari MINT.
10879 [Jan Paul Schmidt <Jan.P.Schmidt mni.fh-giessen.de>]
10881 *) When booting, apache will now detach itself from stdin, stdout,
10882 and stderr. stderr will not be detached until after the config
10883 files have been read so you will be able to see initial error
10884 messages. After that all errors are logged in the error_log.
10885 This makes it more convenient to start apache via rsh, ssh,
10886 or crontabs. [Dean Gaudet] PR#523
10888 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
10889 Also removed the auto-generated link to www.apache.org that was the
10890 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
10892 *) send_fb would not detect aborted connections in some situations.
10895 *) mod_include would use uninitialized data when parsing certain
10896 expressions involving && and ||. [Brian Slesinsky] PR#1139
10898 *) mod_imap should only handle GET methods. [Jay Bloodworth]
10900 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
10902 *) mod_autoindex improperly counted &escapes; as more than one
10903 character in the description. It also improperly truncated
10904 descriptions that were exactly the maximum length.
10907 *) RedirectMatch was not properly escaping the result (PR#1155). Also
10908 "RedirectMatch /advertiser/(.*) $1" is now permitted.
10911 *) mod_include now uses symbolic names to check for request success
10912 and return HTTP errors, and correctly handles all types of
10913 redirections (previously it only did temporary redirect correctly).
10914 [Ken Coar, Roy Fielding]
10916 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
10917 r->filename. Since those two are meant to be in sync with each other
10918 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
10920 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
10921 ["Kaufman, Steven E" <Steven.Kaufman unisys.com>]
10923 *) Inetd mode (which is buggy) uses timeouts without having setup the
10924 jmpbuffer. [Dean Gaudet] PR#1064
10926 *) Work around problem under Linux where a child will start looping
10927 reporting a select error over and over.
10928 [Rick Franchuk <rickf transpect.net>] PR#1107, 987, 588
10930 *) Fixed error in proxy_util.c when looping through multiple host IP
10931 addresses. [Lars Eilebrecht] PR#974
10933 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
10934 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
10935 bytes before writing, but it will never split a log entry across a
10936 buffer boundary. [Dean Gaudet]
10938 *) API: the short_score record has been split into two pieces, one which
10939 the parent writes on, and one which the child writes on. As part of
10940 this change the get_scoreboard_info() function was removed, and
10941 scoreboard_image was exported. This change fixes a race condition
10942 in file based scoreboard systems, and speeds up changes involving the
10943 scoreboard in earlier 1.3 development. [Dean Gaudet]
10945 *) API: New register_other_child() API (see http_main.h) which allows
10946 modules to register children with the parent for maintenance. It
10947 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
10949 *) API: New piped_log API (see http_log.h) which implements piped logs,
10950 and will use register_other_child to implement reliable piped logs
10951 when it is available. The reliable piped logs part can be disabled
10952 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
10953 logs is only available on Unix. [Dean Gaudet]
10955 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
10956 meets_conditions(). This allows conditional HTTP selection to be
10957 handled separately from the storing of the header fields, and provides
10958 the ability for CGIs to set their own ETags for conditional checking.
10959 [Ken Coar, Roy Fielding] PR#895
10961 *) Changes to mod_log_config to allow naming of format strings.
10962 Format nicknames are defined with "LogFormat fmt nickname", and can
10963 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
10966 *) New module, "mod_speling", which can help find files even when
10967 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
10969 *) API: New function child_terminate() triggers the child process to
10970 exit, while allowing the child finish what it needs to for the
10971 current request first.
10972 [Doug MacEachern, Alexei Kosut]
10974 *) Windows now defaults to using full status reports with mod_status.
10975 [Alexei Kosut] PR #1094
10977 *) *Really* disable all mod_rewrite operations if the engine is off.
10978 Some things (like RewriteMaps) were checked/performed even if they
10979 weren't supposed to be. [Ken Coar] PR #991
10981 *) Implement a new timer scheme which eliminates the need to call alarm() all
10982 the time. Instead a counter in the scoreboard for each child is used to
10983 show when the child has made forward progress. The parent samples this
10984 counter every scoreboard maintenance cycle, and issues SIGALRM if no
10985 progress has been made in the timeout period. This reduces the static
10986 request best-case syscall count to 22 from 29. This scheme is only
10987 used by systems with memory-based scoreboards. [Dean Gaudet]
10989 *) The proxy now properly handles CONNECT requests which are sent
10990 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
10992 *) A script called apachectl has been added to the support
10993 directory. This script allows you to do things such as
10994 "apachectl start" and "apachectl restart" from the command
10995 line. [Marc Slemko]
10997 *) Modules and core routines are now put into libraries, which
10998 simplifies the link line tremendously (among other advantages).
11001 *) Some of the MD5 names defined in Apache have been renamed to have
11002 an `ap_' prefix to avoid conflicts with routines supplied by
11003 external libraries. [Ken Coar]
11005 *) Removal of mod_auth_msql.c from the distribution. There are many
11006 other options for databases today. Rather than offer one option,
11007 offer none at this time. mod_auth_msql and other SQL database
11008 authentication modules can be found at the Apache Module Registry.
11009 http://modules.apache.org/ It would be nice to offer a generic
11010 mod_auth_sql option in the near future.
11012 *) PORT: BeOS support added [Alexei Kosut]
11014 *) Configure no longer accepts the -make option, since it creates
11015 Makefile on the fly based on Makefile.tmpl and Configuration.
11017 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
11018 of forcibly killing off all its processes and exiting without
11019 cleaning up. [Alexei Kosut]
11021 *) API: A new field in the request_rec, r->mtime, has been added to
11022 avoid gratuitous parsing of date strings. It is intended to hold
11023 the last-modified date of the resource (if applicable). An
11024 update_mtime() routine has also been added to advance it if
11025 appropriate. [Roy Fielding, Ken Coar]
11027 *) SECURITY: If a htaccess file can not be read due to bad permissions,
11028 deny access to the directory with a HTTP_FORBIDDEN. The previous
11029 behavior was to ignore the htaccess file if it could not be read.
11030 This change may make some setups with unreadable htaccess files
11031 stop working. [Marc Slemko] PR#817
11033 *) Add aplog_error() providing a mechanism to define levels of
11034 verbosity to the server error logging. This addition also provides
11035 the ability to log errors using syslogd. Error logging is configurable
11036 on a per-server basis using the LogLevel directive. Conversion
11037 of log_*() in progress. [Randy Terbush]
11039 *) Further enhance aplog_error() to not log filename, line number, and
11040 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
11042 *) WIN32: Canonicalise filenames under Win32. Short filenames are
11043 converted to long ones. Backslashes are converted to forward
11044 slashes. Case is converted to lower. Parts of URLs that do not
11045 correspond to files are left completely alone. [Ben Laurie]
11047 *) PORT: 2 new OSs added to the list of ports:
11048 Encore's UMAX V: Arieh Markel <amarkel encore.com>
11049 Acorn RISCiX: Stephen Borrill <sborrill xemplar.co.uk>
11051 *) Add the server version (SERVER_VERSION macro) to the "server
11052 configured and running" entry in the error_log. Also build an
11053 object file at link-time that contains the current time
11054 (SERVER_BUILT global const char[]), and include that in the
11055 message. [Ken Coar]
11057 *) Set r->headers_out when sending responses from the proxy.
11058 This fixes things such as the logging of headers sent from
11059 the proxy. [Marc Slemko] PR#659
11061 *) support/httpd_monitor is no longer distributed because the
11062 scoreboard should not be file based if at all possible. Use
11063 mod_status to see current server snapshot.
11065 *) (set_file_slot): New function, allowing auth directives to be
11066 independent of the server root, so the server documents can be
11067 moved to a different directory or machine more easily.
11068 [David J. MacKenzie]
11070 *) If no TransferLog is given explicitly, decline
11071 to log. This supports coexistence with other logging modules,
11072 such as the custom one that UUNET uses. [David J. MacKenzie]
11074 *) Check for titles in server-parsed HTML files.
11075 Ignore leading newlines and returns in titles. The old behavior
11076 of replacing a newline after <title> with a space causes the
11077 title to be misaligned in the listing. [David J. MacKenzie]
11079 *) Change mod_cern_meta to be configurable on a per-directory basis.
11080 [David J. MacKenzie]
11082 *) Add 'Include' directive to allow inclusion of configuration
11083 files within configuration files. [Randy Terbush]
11085 *) Proxy errors on connect() are logged to the error_log (nothing
11086 new); now they include the IP address and port that failed
11087 (*that's* new). [Ken Coar, Marc Slemko] PR#352
11089 *) Various architectures now define USE_MMAP_FILES which causes
11090 the server to use mmap() for static files. There are two
11091 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
11092 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
11093 number of bytes written in one cycle from a single mmap()d object,
11094 default 32768). [Dean Gaudet]
11096 *) API: Added post_read_request API phase which is run right after reading
11097 the request from a client, or right after an internal redirect. It is
11098 useful for modules setting environment variables that depend only on
11099 the headers/contents of the request. It does not run during subrequests
11100 because subrequests inherit pretty much everything from the main
11101 request. [Dean Gaudet]
11103 *) Added mod_unique_id which is used to generate a unique identifier for
11104 each hit, available in the environment variable UNIQUE_ID.
11107 *) init_modules is now called after the error logs have been opened. This
11108 allows modules to emit information messages into the error logs.
11111 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11112 information for case where proxy module is not available. [Marc Slemko]
11114 *) PORT: Apache has need for mutexes to serialize its children around
11115 accept. In prior versions either fcntl file locking or flock file
11116 locking were used. The method is chosen by the definition of
11117 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
11118 and FLOCK for flock(). New options have been added:
11119 - SYSVSEM to use System V style semaphores
11120 - PTHREAD to use POSIX threads (appears to work on Solaris only)
11121 - USLOCK to use IRIX uslock
11122 Based on timing various techniques, the following changes were made
11124 - Linux 2.x uses flock instead of fcntl
11125 - Solaris 2.x uses pthreads
11126 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
11127 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
11128 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec vtcom.fr>,
11129 Martijn Koster <m.koster pobox.com>]
11131 *) PORT: The semantics of accept/select make it very desirable to use
11132 mutexes to serialize accept when multiple Listens are in use. But
11133 in the case where only a single socket is open it is sometimes
11134 redundant to serialize accept(). Not all unixes do a good job with
11135 potentially dozens of children blocked on accept() on the same
11136 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
11137 the server will avoid serialization when listening on only one socket,
11138 and use serialization when listening on multiple sockets.
11139 [Dean Gaudet] PR#467
11141 *) Configure changes: TestLib replaced by TestCompile, which has
11142 some additional capability (such as doing a sanity check of
11143 the compiler and flags selected); the version of Solaris is now
11144 available via the #define value of SOLARIS2; IRIX n32bit libs
11145 now supported and selectable by new Configuration Rule: IRIXN32;
11146 We no longer default to -O2 optimization. [Jim Jagielski]
11148 *) Updated Configure: Configuration now uses AddModule to specify
11149 module source or binary file location, relative to src directory.
11150 Modules can be dropped into modules/extra, or in their own
11151 directory, and modules can come with a Makefile or Configure can
11152 create one. Modules can add compiler or library information to
11153 generated Makefiles. [Paul Sutton]
11155 *) Source core re-organisation: distributed modules are now in
11156 modules/standard. All other source code is in main. OS-specific
11157 code is in os/{unix,emx,win32} directories. [Paul Sutton]
11159 *) mod_browser has been removed, since it's replaced by mod_setenvif.
11162 *) Fix another long-standing bug in sub_req_lookup_file where it would
11163 happily skip past access checks on subdirectories looked up with
11164 relative paths. (It's used by mod_dir, mod_negotiation,
11165 and mod_include.) [Dean Gaudet]
11167 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
11168 N is the number of <Directory> sections, and M is the number of
11169 components in the filename of an object.
11171 To achieve this optimization the following config changes were made:
11172 - Wildcards (* and ?, not the regex forms) in <Directory>s,
11173 <Files>s, and <Location>s now treat a slash as a special
11174 character. For example "/home/*/public_html" previously would
11175 match "/home/a/andrew/public_html", now it only matches things
11176 like "/home/bob/public_html". This mimics /bin/sh behaviour.
11177 - It's possible now to use [] wildcarding in <Directory>, <Files>
11179 - Regex <Directory>s are applied after all non-regex <Directory>s.
11183 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
11184 and corrupted paths. [Dean Gaudet]
11186 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
11187 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
11188 be accessed now via backreferences $1..$9 in RewriteConds test-against
11189 strings in addition to RewriteRules subst string. Second the grouped
11190 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
11191 via backreferences %1..%9 both in following RewriteCond test-against
11192 strings and RewriteRules subst string. This provides maximum flexibility
11193 through the use of backreferences.
11194 Additionally the rewriting engine was cleaned up by putting common
11195 code to the new expand_backrefs_inbuffer() function.
11196 [Ralf S. Engelschall]
11198 *) When merging the main server's <Directory> and <Location> sections into
11199 a vhost, put the main server's first and the vhost's second. Otherwise
11200 the vhost can't override the main server. [Dean Gaudet] PR#717
11202 *) The <Directory> code would merge and re-merge the same section after
11203 a match was found, possibly causing problems with some modules.
11206 *) ip-based vhosts are stored and queried using a hashing function, which
11207 has been shown to improve performance on servers with many ip-vhosts.
11208 Some other changes had to be made to accommodate this:
11209 - the * address for vhosts now behaves like _default_
11210 - the matching process now is:
11211 - match an ip-vhost directly via hash (possibly matches main
11213 - if that fails, just pretend it matched the main server
11214 - if so far only the main server has been matched, perform
11215 name-based lookups (ServerName, ServerAlias, ServerPath)
11216 *only on name-based vhosts*
11217 - if they fail, look for _default_ vhosts
11218 [Dean Gaudet, Dave Hankins <dhankins sugarat.net>]
11220 *) dbmmanage overhaul:
11221 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
11222 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
11223 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
11224 - provide better seed for rand
11225 - prompt for password as per getpass(3) (turn off echo, read from
11227 - use "newstyle" crypt based on $Config{osname} ($^O)
11228 - will not add a user if already in database, use new `update' command
11230 - added `check' command to check a users' password
11231 - added `import' command to convert existing password text-files or
11232 dbm files exported with `view'
11233 - more descriptive usage, general cleanup, 'use strict' clean, etc.
11236 *) Added psocket() which is a pool form of socket(), various places within
11237 the proxy weren't properly blocking alarms while registering the cleanup
11238 for its sockets. bclose() now uses pclose() and pclosesocket(). There
11239 was a bug where the client socket was being close()d twice due a still
11240 registered cleanup. [Dean Gaudet]
11242 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
11245 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
11246 [Jason Venner <jason idiom.com>] PR#667
11248 *) Enable ``=""'' for RewriteCond directives to match against
11249 the empty string. This is the preferred way instead of ``^$''.
11250 [Ralf S. Engelschall]
11252 *) Fixed an infinite loop in mod_imap for references above the server root
11253 [Dean Gaudet] PR#748
11255 *) mod_proxy now has a ReceiveBufferSize directive, similar to
11256 SendBufferSize, so that the TCP window can be set appropriately
11257 for LFNs. [Phillip A. Prindeville]
11259 *) mod_browser has been replaced by the more general mod_setenvif
11260 (courtesy of Paul Sutton). BrowserMatch* directives are still
11261 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
11262 UnSetEnvIfZero directives. [Ken Coar]
11264 *) "HostnameLookups double" forces double-reverse DNS to succeed in
11265 order for remote_host to be set (for logging, or for the env var
11266 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
11269 *) mod_access overhaul:
11270 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
11271 and cidr syntax (i.e. 10.1.0.0/16). PR#762
11272 - Critical path was sped up by pre-computing a few things at config time.
11273 - The undocumented syntax "allow user-agents" was removed,
11274 the replacement is "allow from env=foobar" combined with mod_browser.
11275 - When used with hostnames it now forces a double-reverse lookup
11276 no matter what the directory settings are. This double-reverse
11277 doesn't affect any of the other routines that use the remote
11278 hostname. In particular it's still passed to CGIs and the log
11279 without the double-reverse check. Related PR#860.
11282 *) When a large bwrite() occurs (larger than the internal buffer size),
11283 while there is already something in the buffer, apache will combine
11284 the large write and the buffer into a single writev(). (This is
11285 in anticipation of using mmap() for reading files.)
11288 *) In obscure cases where a partial socket write occurred while chunking,
11289 Apache would omit the chunk header/footer on the next block. Cleaned
11290 up other bugs/inconsistencies in error conditions in buff.c. Fixed
11291 a bug where a long pause in DNS lookups could cause the last packet
11292 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
11294 *) API: Added child_exit function to module structure. This is called
11295 once per "heavy-weight process" just before a server child exit()'s
11296 e.g. when max_requests_per_child is reached, etc.
11297 [Doug MacEachern, Dean Gaudet]
11299 *) mod_include cleanup showed that handle_else was being used to handle
11300 endif. It didn't cause problems, but it was cleaned up too.
11303 *) mod_cern_meta would attempt to find meta files for the directory itself
11304 in some cases, but not in others. It now avoids it in all cases.
11307 *) mod_mime_magic would core dump if there was a decompression error.
11308 [Martin Kraemer <Martin.Kraemer mch.sni.de>] PR#904
11310 *) PORT: some variants of DGUX require -lsocket -lnsl
11311 [Alexander L Jones <alex systems-options.co.uk>] PR#732
11313 *) mod_autoindex now allows sorting of FancyIndexed directory listings
11314 by the various fields (name, size, et cetera), either in ascending
11315 or descending order. Just click on the column header. [Ken Coar]
11317 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
11318 CPUs like the Alpha. Apache still stores ints in pointers, but that's
11319 the relatively safe direction. [Dean Gaudet] PR#344
11321 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
11322 [Igor N Kovalenko <infoh mail.wplus.net>] PR#683
11324 *) child_main avoids an unneeded call to select() when there is only one
11325 listening socket. [Dean Gaudet]
11327 *) In the event that the server is starved for idle servers it will
11328 spawn 1, then 2, then 4, ..., then 32 servers each second,
11329 doubling each second. It'll also give a warning in the errorlog
11330 since the most common reason for this is a poor StartServers
11331 setting. The define MAX_SPAWN_RATE can be used to raise/lower
11332 the maximum. [Dean Gaudet]
11334 *) Apache now provides an effectively unbuffered connection for
11335 CGI scripts. This means that data will be sent to the client
11336 as soon as the CGI pauses or stops output; previously, Apache would
11337 buffer the output up to a fixed buffer size before sending, which
11338 could result in the user viewing an empty page until the CGI finished
11339 or output a complete buffer. It is no longer necessary to use an
11340 "nph-" CGI to get unbuffered output. Given that most CGIs are written
11341 in a language that by default does buffering (e.g. perl) this
11342 shouldn't have a detrimental effect on performance.
11344 "nph-" CGIs, which formerly provided a direct socket to the client
11345 without any server post-processing, were not fully compatible with
11346 HTTP/1.1 or SSL support. As such they would have had to implement
11347 the transport details, such as encryption or chunking, in order
11348 to work properly in certain situations. Now, the only difference
11349 between nph and non-nph scripts is "non-parsed headers".

11352 *) If a BUFF is switched from buffered to unbuffered reading the first
11353 bread() will return whatever remained in the buffer prior to the
11354 switch. [Dean Gaudet]
11356 Changes with Apache 1.3a1
11358 *) Added another Configure helper script: TestLib. It determines
11359 if a specified library exists. [Jim Jagielski]
11361 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
11362 [derived from patch from Jeff Hayes <jhayes aw.sgi.com>]
11365 *) PORT: Some architectures use size_t for various lengths in network
11366 functions such as accept(), and getsockname(). The definition
11367 NET_SIZE_T is used to control this. [Dean Gaudet]
11369 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
11370 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
11371 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
11373 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
11374 [Igor N Kovalenko <infoh mail.wplus.net>]
11376 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11377 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11378 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11379 [Dean Gaudet] related PR#875
11381 *) API: Correct child_init() slot declaration from int to void, to
11382 match the init() declaration. Update mod_example to use the new
11385 *) added transport handle slot (t_handle) to the BUFF structure
11388 *) get_client_block() returns wrong length if policy is
11389 REQUEST_CHUNKED_DECHUNK.

11397 ["Darren O'Shaughnessy" <darren aaii.oz.au>] PR#846
11399 *) AddModuleInfo directive for mod_info which allows you to annotate
11400 the output of mod_info. ["Lou D. Langholtz" <ldl usi.utah.edu>]
11402 *) Added NoProxy directive to avoid using ProxyRemote for selected
11403 addresses. Added ProxyDomain directive to cause unqualified
11404 names to be qualified by redirection.
11405 [Martin Kraemer <Martin.Kraemer mch.sni.de>]
11407 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
11408 header to the remote host in the proxy. [Sameer Parekh and
11411 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
11412 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
11413 URLs, fixed rewritelog(), fixed forced response code handling on
11414 redirects from within .htaccess files, disabled pipe locking under
11415 braindead SunOS 4.1.x, allow env variables to be set even on rules with
11416 no substitution, bugfixed situations where HostnameLookups is off, made
11417 mod_rewrite more thread-safe for NT port and fixed problem when creating
11418 an empty query string via "xxx?".
11419 This update also removes the copyright of Ralf S. Engelschall,
11420 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
11421 exclusively copyrighted by the Apache Group now. This happened because
11422 the author now has gifted mod_rewrite exclusively to the Apache Group and
11423 no longer maintains an external version.
11424 [Ralf S. Engelschall]
11426 *) API: Added child_init function to module structure. This is called
11427 once per "heavy-weight process" before any requests are handled.
11428 See http_config.h for more details. [Dean Gaudet]
11430 *) Anonymous_LogEmail was logging on each subrequest.
11431 [Dean Gaudet] PR#421, 868
11433 *) API: Added is_initial_req() which tests if the request being
11434 processed is the initial request, or a subrequest.
11437 *) Extended SSI (mod_include) now handles additional relops for
11438 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
11440 *) Configure fixed to correctly propagate user-selected options and
11441 settings (such as CC and OPTIM) to Makefiles other than
11442 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
11444 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
11445 directory indices to start with the contents of the HeaderName file
11446 if there is one. If there isn't one, the behaviour is unchanged.
11447 [Ken Coar, Roy Fielding, Andrey A. Chernov]
11449 *) WIN32: Modules can now be dynamically loaded DLLs using the
11450 LoadModule/LoadFile directives. Note that module DLLs must be
11451 compiled with the multithreaded DLL version of the runtime library.
11452 [Alexei Kosut and Ben Laurie]
11454 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
11455 This allows the admin to completely remove automatic indexing
11456 from the server, while still supporting the basic functions of
11457 trailing-slash redirects and DirectoryIndex files. Note that if
11458 you're carrying over an old Configuration file and you use directory
11459 indexing then you'll want to add:
11461 Module autoindex_module mod_autoindex.o
11463 before mod_dir in your Configuration. [Dean Gaudet]
11465 *) popendir/pclosedir created to properly protect directory scanning.
11466 [Dean Gaudet] PR#525
11468 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
11469 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
11470 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
11473 *) The AccessFileName directive can now take more than one filename.
11474 ["Lou D. Langholtz" <ldl usi.utah.edu>]
11476 *) The new mod_mime_magic can be used to "magically" determine the type
11477 of a file if the extension is unknown. Based on the unix file(1)
11478 command. [Ian Kluft <ikluft cisco.com>]
11480 *) We now determine and display the time spent processing a
11481 request if desired. [Jim Jagielski]
11483 *) mod_status: PID field of "dead" child slots no longer displays
11484 main httpd process's PID. [Jim Jagielski]
11486 *) Makefile.nt added - to build all the bits from the command line:
11487 nmake -f Makefile.nt
11488 Doesn't yet work properly. [Ben Laurie]
11490 *) Default text of 404 error is now "Not Found" rather than the
11491 potentially misleading "File Not Found". [Ken Coar]
11493 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
11494 for the net if we require people that actually need this data to
11495 enable it. [Linus Torvalds]
11497 *) directory_walk() is an expensive function, keep a little more state to
11498 avoid needless string counting. Add two new functions make_dirstr_parent
11499 and make_dirstr_prefix which replace all existing uses of make_dirstr.
11500 The new functions are a little less general than make_dirstr, but
11501 work more efficiently (less memory, less string counting).
11504 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
11505 to LDFLAGS) to avoid complications with lex rules in make files.
11506 [Dean Gaudet] PR#372
11508 *) run_method optimized to avoid needless scanning over NULLs in the
11509 module list. [Dean Gaudet]
11511 *) Revamp of (unix) scoreboard management code such that it avoids
11512 unnecessary traversals of the scoreboard on each hit. This is
11513 particularly important for high volume sites with a large
11514 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
11515 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
11516 httpd.h. [Dean Gaudet]
11518 *) In configurations using multiple Listen statements it was possible for
11519 busy sockets to starve other sockets of service. [Dean Gaudet]
11521 *) Added hook so standalone_main can be replaced at compile time
11522 (define STANDALONE_MAIN)
11525 *) Lowest-level read/write functions in buff.c will be replaced with
11526 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
11527 compile time. The default sfio discipline will behave as apache
11528 would without sfio compiled in.
11531 *) Enhance UserDir directive (mod_userdir) to accept a list of
11532 usernames for the 'disable' keyword, and add 'enable user...' to
11533 selectively *en*able userdirs if they're globally disabled.
11536 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
11537 will work with Netscape dbm files. (dbmmanage will probably not
11538 work however.) [Alexander Spohr <aspohr netmatic.com>] PR#444
11540 *) Add a ListenBacklog directive to control the backlog parameter
11541 passed to listen(). Also change the default to 511 from 512.
11544 *) API: A new handler response DONE which informs apache that the
11545 request has been handled and it can finish off quickly, similar to
11546 how it handles errors. [Rob Hartill]
11548 *) Turn off chunked encoding after sending terminating chunk/footer
11549 so that we can't do it twice by accident. [Roy Fielding]
11551 *) mod_expire also issues Cache-Control: max-age headers.
11554 *) API: Added kill_only_once option for free_proc_chain so that it won't
11555 aggressively try to kill off specific children. For fastcgi.
11556 [Stanley Gambarin <gambarin OpenMarket.com>]
11558 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
11560 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
11561 When used together, these cause mod_dir to emit HEIGHT and WIDTH
11562 attributes in the FancyIndexing IMG tags. [Ken Coar]
11564 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
11566 *) PORT: Added Windows NT support
11567 [Ben Laurie and Ambarish Malpani <ambarish valicert.com>]
11569 Changes with Apache 1.2.6
11571 *) mod_include when using XBitHack Full would send ETags in addition to
11572 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
11573 [Dean Gaudet] PR#1133
11575 *) SECURITY: When a client connects to a particular port/addr, and
11576 gives a Host: header ensure that the virtual host requested can
11577 actually be reached via that port/addr. [Ed Korthof <ed organic.com>]
11579 *) Support virtual hosts with wildcard port and/or multiple ports
11580 properly. [Ed Korthof <ed organic.com>]
11582 *) Fixed some case-sensitivity issues according to RFC2068.
11585 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
11586 and mod_include.c. [Dean Gaudet]
11588 *) Variable 'cwd' was being used pointlessly before being set.
11591 *) SIGURG doesn't exist on all platforms.
11592 [Mark Andrew Heinrich <heinrich tinderbox.Stanford.EDU>]
11594 *) When an error occurs during a POST, or other operation with a

11605 *) send_fd_length() did not calculate total_bytes_sent properly in error
11606 cases. [Ben Reser <breser regnow.com>] PR#1366
11608 *) r->connection->user was allocated in the wrong pool causing corruption
11609 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
11611 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
11612 Also removed the auto-generated link to www.apache.org that was the
11613 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
11615 *) Multiple "close" tokens may have been set in the "Connection"
11616 header, not an error, but a waste.
11617 [<Ronald.Tschalaer psi.ch>] PR#1683
11619 *) "basic" and "digest" auth tokens should be tested case-insensitive.
11620 [<Ronald.Tschalaer psi.ch>] PR#1599, PR#1666
11622 *) It appears the "257th byte" bug (see
11623 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
11624 at the 256th byte as well. Fixed. [Dean Gaudet]
11626 *) mod_rewrite would not handle %3f properly in some situations.
11629 *) Apache could generate improperly chunked HTTP/1.1 responses when
11630 the bputc() or rputc() functions were used by modules (such as
11631 mod_include). [Dean Gaudet]
11633 *) #ifdef wrap a few #defines in httpd.h to make life easier on
11634 some ports. [Ralf Engelschall]
11636 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
11638 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
11640 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
11642 Changes with Apache 1.2.5
11644 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
11645 only an issue on systems without a MAXDNAME define or where
11646 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
11648 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
11651 *) Fix core dump in the ftp proxy when reading incorrectly formatted
11652 directory listings. [Marc Slemko]
11654 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
11657 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
11658 is used to read various types of files such as htaccess and
11659 htpasswd files. [Marc Slemko]
11661 *) SECURITY: Ensure that the buffer returned by ht_time is always
11662 properly null terminated. [Marc Slemko]
11664 *) SECURITY: General mod_include cleanup, including fixing several
11665 possible buffer overflows and a possible infinite loop. This cleanup
11666 was done against 1.3 code and then backported to 1.2, the result
11667 is a large difference (due to indentation cleanup in 1.3 code).
11668 Users interested in seeing a smaller set of relevant differences
11669 should consider comparing against src/modules/standard/mod_include.c
11670 from the 1.3b3 release. Non-indentation changes to mod_include
11671 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
11673 *) SECURITY: Numerous changes to mod_imap in a general cleanup
11674 including fixing a possible buffer overflow. This cleanup also
11675 was done with 1.3 code as a basis, see the previous note
11676 about mod_include. [Dean Gaudet]
11678 *) SECURITY: If a htaccess file can not be read due to bad
11679 permissions, deny access to the directory with a HTTP_FORBIDDEN.
11680 The previous behavior was to ignore the htaccess file if it could not
11681 be read. This change may make some setups with unreadable
11682 htaccess files stop working. PR#817 [Marc Slemko]
11684 *) SECURITY: no2slash() was O(n^2) in the length of the input.
11685 Make it O(n). This inefficiency could be used to mount a denial
11686 of service attack against the Apache server. Thanks to
11687 Michal Zalewski <lcamtuf boss.staszic.waw.pl> for reporting
11688 this. [Dean Gaudet]

11696 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
11698 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
11699 r->filename. Since those two are meant to be in sync with each other
11700 this is a bug. ["Paul B. Henson" <henson intranet.csupomona.edu>]
11702 *) mod_include did not properly handle all possible redirects from sub-

11712 Changes with Apache 1.2.4

11715 always making requests with the full-URI instead of just the URI path.
11716 [Marc Slemko, Roy Fielding]
11718 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
11719 on this platform. [Marc Slemko]
11721 Changes with Apache 1.2.3
11723 *) The request to a remote proxy was mangled if it was generated as the
11724 result of a ProxyPass directive. URL schemes other than http:// were not
11725 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

11728 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
11729 information for case where proxy module is not available. [Marc Slemko]
11731 *) Force proxy to always respond as HTTP/1.0, which it was failing to
11732 do for errors and cached responses. [Roy Fielding]
11734 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
11736 Changes with Apache 1.2.2 [not released]
11738 *) Fixed another long-standing bug in sub_req_lookup_file where it would
11739 happily skip past access checks on subdirectories looked up with relative
11740 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
11743 *) Add lockfile name to error message printed out when
11744 USE_FLOCK_SERIALIZED_ACCEPT is defined.
11747 *) Enhanced the chunking and error handling inside the buffer functions.
11748 [Dean Gaudet, Roy Fielding]
11750 *) When merging the main server's <Directory> and <Location> sections into
11751 a vhost, put the main server's first and the vhost's second. Otherwise
11752 the vhost can't override the main server. [Dean Gaudet] PR#717
11754 *) The <Directory> code would merge and re-merge the same section after
11755 a match was found, possibly causing problems with some modules.
11758 *) Fixed an infinite loop in mod_imap for references above the server root.
11759 [Dean Gaudet] PR#748
11761 *) mod_include cleanup showed that handle_else was being used to handle
11762 endif. It didn't cause problems, but it was cleaned up too.
11765 *) Last official synchronization of mod_rewrite with author version (because
11766 mod_rewrite is now directly developed by the author at the Apache Group):
11767 o added diff between mod_rewrite 3.0.6+ and 3.0.9
11768 minus WIN32/NT stuff, but plus copyright removement.
11770 - workaround for detecting infinite rewriting loops
11771 - fixed setting of env vars when "-" is used as subst string

11773 - fixed cases where r->args is ""
11774 - kludge to disable locking on pipes under braindead SunOS
11775 - fix for rewritelog in cases where remote hostname is unknown
11776 - fixed totally damaged request_rec walk-back loop
11777 o remove static from local data and add static to global ones.
11778 o replaced ugly proxy finding stuff by simple
11779 find_linked_module("mod_proxy") call.
11780 o added missing negation char on rewritelog()

11787 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
11788 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
11789 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
11790 Additionally mod_browser now triggers during translate_name to workaround
11791 a deficiency in the header_parse phase.

11809 under Solaris 2.x (up through 2.5.1). It has been fixed.
11810 [Dean Gaudet] PR#832
11812 *) API: In HTTP/1.1, whether or not a request message contains a body
11813 is independent of the request method and based solely on the presence
11814 of a Content-Length or Transfer-Encoding. Therefore, our default
11815 handlers need to be prepared to read a body even if they don't know
11816 what to do with it; otherwise, the body would be mistaken for the
11817 next request on a persistent connection. discard_request_body()
11818 has been added to take care of that. [Roy Fielding] PR#378
11820 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
11821 release version number, such that it always increases along the
11822 same lines as our source code branching. [Roy Fielding]
11824 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
11826 Changes with Apache 1.2.1
11828 *) SECURITY: Don't serve file system objects unless they are plain files,
11829 symlinks, or directories. This prevents local users from using pipes
11830 or named sockets to invoke programs for an extremely crude form of
11833 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
11834 could contain "../" allowing a local user to "publish" any file on
11835 the system. No slashes are allowed now. [Dean Gaudet]
11837 *) SECURITY: It was possible to violate the symlink Options using mod_dir
11838 (headers, readmes, titles), mod_negotiation (type maps), or
11839 mod_cern_meta (meta files). [Dean Gaudet]
11841 *) SECURITY: Apache will refuse to run as "User root" unless
11842 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
11844 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
11845 if it contained a .htaccess disallowing symlinks. This is contrary
11846 to the rule that symlink permissions are tested with the symlink
11847 options of the parent directory. [Dean Gaudet] PR#353
11849 *) CONFIG: The LockFile directive can be used to place the serializing
11850 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
11851 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
11854 *) Request processing now retains state of whether or not the request
11855 body has been read, so that internal redirects and subrequests will
11856 not try to read it twice (and block). [Roy Fielding]
11858 *) Add a placeholder in modules/Makefile to avoid errors with certain
11859 makes. [Marc Slemko]
11861 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
11862 [Dean Gaudet] PR#644
11864 *) mod_include was not properly changing the current directory.
11865 [Marc Slemko] PR#742
11867 *) Attempt to work around problems with third party libraries that do not
11868 handle high numbered descriptors (examples include bind, and
11869 solaris libc). On all systems apache attempts to keep all permanent
11870 descriptors above 15 (called the low slack line). Solaris users
11871 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
11872 which keeps all non-FILE * descriptors above 255. On all systems
11873 this should make supporting large numbers of vhosts with many open
11874 log files more feasible. If this causes trouble please report it,
11875 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
11876 [Dean Gaudet] various PRs
11878 *) Related to the last entry, network sockets are now opened before
11879 log files are opened. The only known case where this can cause
11880 problems is under Solaris with many virtualhosts and many Listen
11881 directives. But using -DHIGH_SLACK_LINE=256 described above will
11882 work around this problem. [Dean Gaudet]
11884 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
11887 *) Improved unix error response logging. [Marc Slemko]
11889 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
11890 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
11891 when a URL http://... was used in conjunction with a special
11892 redirect flag, e.g. R=permanent, the permanent status was lost.

11933 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
11934 [Doug MacEachern, Rob Hartill]
11936 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
11937 reading from one buffer and writing to another, at least until it has
11938 a custom timeout handler. [Roy Fielding and Petr Lampa]
11940 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
11941 apparently due to a mismatch between sigaction and setjmp.
11942 [Roy Fielding] PR#502
11944 *) Log correct status code if we timeout before receiving a request (408)
11945 or if we received a request-line that was too long to process (414).
11946 [Ed Korthof and Roy Fielding] PR#601
11948 *) Virtual hosts with the same ServerName, but on different ports, were
11949 not being selected properly. [Ed Korthof]
11951 *) Added code to return the requested IP address from proxy_host2addr()
11952 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
11953 change submitted by Jozsef Hollosi <hollosi sbcm.com>.
11954 [Chuck Murcko] PR#614
11956 *) If multiple requests on a single connection are used to retrieve
11957 data from different virtual hosts, the virtual host list would be
11958 scanned starting with the most recently used VH instead of the first,
11959 causing most virtual hosts to be ignored.
11960 [Paul Sutton and Martin Mares] PR#610
11962 *) The OS/2 handling of process group was broken by a porting patch for
11963 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
11965 *) Inherit virtual server port from main server if none (or "*") is
11966 given for VirtualHost. [Dean Gaudet] PR#576
11968 *) If the lookup for a DirectoryIndex name with content negotiation
11969 has found matching variants, but none are acceptable, return the
11970 negotiation result if there are no more DirectoryIndex names to lookup.
11971 [Petr Lampa and Roy Fielding]
11973 *) If a soft_timeout occurs after keepalive is set, then the main child
11974 loop would try to read another request even though the connection
11975 has been aborted. [Roy Fielding]
11977 *) Configure changes: Allow for whitespace at the start of a
11978 Module declaration. Also, be more understanding about the
11979 CC=/OPTIM= format in Configuration. Finally, fix compiler
11980 flags if using HP-UX's cc compiler. [Jim Jagielski]
11982 *) Subrequests and internal redirects now inherit the_request from the
11983 original request-line. [Roy Fielding]
11985 *) Test for error conditions before creating output header fields, since
11986 we don't want the error message to include those fields. Likewise,
11987 reset the content_language(s) and content_encoding of the response
11988 before generating or redirecting to an error message, since the new
11989 message will have its own Content-* definitions. [Dean Gaudet]
11991 *) Restored the semantics of headers_out (headers sent only with 200..299
11992 and 304 responses) and err_headers_out (headers sent with all responses).
11993 Avoid the overhead of copying tables if err_headers_out is empty
11994 (the usual case). [Roy Fielding]
11996 *) Fixed a couple places where a check for the default Content-Type was
11997 not properly checking both the value configured by the DefaultType
11998 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
11999 of DEFAULT_TYPE to match the documented default (text/plain).
12000 [Dean Gaudet] PR#506
12002 *) Escape the HTML-sensitive characters in the Request-URI that is
12003 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
12005 *) Properly initialize the flock structures used by the mutex locking
12006 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
12009 *) The method for determining PATH_INFO has been restored to the pre-1.2b
12010 (and NCSA httpd) definition wherein it was the extra path info beyond
12011 the CGI script filename. The environment variable FILEPATH_INFO has
12012 been removed, and instead we supply the original REQUEST_URI to any
12013 script that wants to be Apache-specific and needs the real URI path.
12014 This solves a problem with existing scripts that use extra path info
12015 in the ScriptAlias directive to pass options to the CGI script.
12018 *) The _default_ change in 1.2b10 will change the behaviour on configs
12019 that use multiple Listen statements for listening on multiple ports.
12020 But that change is necessary to make _default_ consistent with other
12021 forms of <VirtualHost>. It requires such configs to be modified
12022 to use <VirtualHost _default_:*>. The documentation has been
12023 updated. [Dean Gaudet] PR#530
12025 *) If an ErrorDocument CGI script is used to respond to an error
12026 generated by another CGI script which has already read the message
12027 body of the request, the server would block trying to read the
12028 message body again. [Rob Hartill]
12030 *) signal() replacement conflicted with a define on QNX (and potentially
12031 other platforms). Fixed. [Ben Laurie] PR#512
12033 Changes with Apache 1.2b10
12035 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
12036 to be configured via -D in Configuration. [Dean Gaudet] PR#449
12038 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
12040 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]

12043 config, in case the hostent struct returned is trash.
12044 [Chuck Murcko] PR #491
12046 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
12047 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
12049 Changes with Apache 1.2b9 [never announced]
12051 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
12052 changes and in anticipation of 1.2 final release. [Roy Fielding]
12054 *) Fix problem with scripts not receiving a SIGPIPE when client drops
12055 the connection (e.g., when user presses Stop). Apache will now stop
12056 trying to send a message body immediately after an error from write.
12057 [Roy Fielding and Nathan Kurz] PR#335
12059 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
12060 than mod_alias, and mod_alias has higher priority than mod_proxy;
12061 rearranged other modules to enhance understanding of their purpose
12062 and relative order (and maybe even reduce some overhead).
12063 [Roy Fielding and Sameer Parekh]
12065 *) Fix graceful restart. Eliminate many signal-related race
12066 conditions in both forms of restart, and in SIGTERM. See
12067 htdocs/manual/stopping.html for details on stopping and
12068 restarting the parent. [Dean Gaudet]
12070 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
12071 memory allocator to avoid a behaviour that required extra blocks to
12072 be allocated. [Dean Gaudet]
12074 *) Allow suexec to access files relative to current directory but not
12075 above. (Excluding leading / or any .. directory.) [Ken Coar]
12078 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
12079 PR#367, 368, 354, 453
12081 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
12082 while obtaining the /~user and save the username in a separate data
12083 area so that it won't be overwritten by the call to getgrgid(), and
12084 fix some misuse of the pool string allocation functions. Also fixes
12085 a general problem with parsing URL query info into args for CGI scripts.

12093 AuthDBAuthoritative. [Marc Slemko] PR#420
12095 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
12097 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
12098 object that can't be PUT, or FOOBAR for some method FOOBAR that
12099 apache doesn't know about at all). Log 404s that occur in mod_include.
12100 [Paul Sutton, John Van Essen]
12102 *) If a soft timeout (or lingerout) occurs while trying to flush a
12103 buffer or write inside buff.c or fread'ing from a CGI's output,
12104 then the timeout would be ignored. [Roy Fielding] PR#373
12106 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
12107 parsing of headers. If the terminating empty-line CRLF occurs starting
12108 at the 256th or 257th byte of output, then Navigator will think a normal
12109 image is invalid. We are guessing that this is because their initial
12110 read of a new request uses a 256 byte buffer. We check the bytes written
12111 so far and, if we are about to tickle the bug, we instead insert a
12112 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
12114 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
12115 of an external redirection. [Roy Fielding and Paul Sutton]
12117 *) Configure would create a broken Makefile if the configuration file
12118 contained a commented-out Rule. [Roy Fielding]
12120 *) Promote per_dir_config and subprocess_env from the subrequest to the
12121 main request in mod_negotiation. In particular this fixes a bug
12122 where <Files> sections wouldn't properly apply to negotiated content.
12125 *) Fix a potential deadlock in mod_cgi script_err handling.
12126 [Ralf S. Engelschall]
12128 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
12129 [Mitchell Blank Jr]
12131 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
12132 .htaccess files because the RewriteBase was not replaced correctly.
12133 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
12134 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
12136 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
12137 1.x the settings are those of pre-1.2b8. For 2.x we include
12138 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
12139 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
12140 [Dean Gaudet] PR#336, PR#340
12142 *) Redirect did not preserve ?query_strings when present in the client's
12143 request. [Dean Gaudet]
12145 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
12147 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
12149 *) Add UnixWare compile/install instructions. [Chuck Murcko]
12151 *) Add mod_example (illustration of API techniques). [Ken Coar]
12153 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
12155 *) Improve handling of directories when filenames have spaces in them.
12158 *) For hosts with multiple IP addresses, try all additional addresses if
12159 necessary to get a connect. Fail only if hostent address list is
12160 exhausted. [Chuck Murcko]
12162 *) More signed/unsigned port fixes. [Dean Gaudet]
12164 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
12167 Changes with Apache 1.2b8
12169 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
12170 to it. [Marc Slemko]
12172 *) The addition of <Location> and <File> directives made the
12173 sub_req_lookup_simple() function bogus, so we now handle
12174 the special cases directly. [Dean Gaudet]
12176 *) We now try to log where the server is dumping core when a fatal
12177 signal is received. [Ken Coar]
12179 *) Improved lingering_close by adding a special timeout, removing the
12180 spurious log messages, removing the nonblocking settings (they
12181 are not needed with the better timeout), and adding commentary
12182 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
12183 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
12185 *) Send error messages about setsockopt failures to the server error
12186 log instead of stderr. [Roy Fielding]
12188 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
12190 *) Stopgap solution for CGI 3-second delay with server-side includes: if
12191 processing a subrequest, allocate memory from r->main->pool instead
12192 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
12193 in the middle of an SSI request. [Dean Gaudet] PR #122
12195 *) Fixed status of response when POST is received for a nonexistent URL
12196 (was sending 405, now 404) and when any method is sent with a
12197 full-URI that doesn't match the server and the server is not acting
12198 as a proxy (was sending 501, now 403). [Roy Fielding]
12200 *) Host port changed to unsigned short. [Ken Coar] PR #276
12202 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
12204 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
12206 *) Report extra info from errno with many errors that cause httpd to exit.
12207 spawn_child, popenf, and pclosef now have valid errno returns in the
12208 event of an error. Correct problems where errno was stomped on
12209 before being reported. [Dean Gaudet]
12211 *) In the proxy, if the cache filesystem was full, garbage_coll() was
12212 never called, and thus the filesystem would remain full indefinitely.
12213 We now also remove incomplete cache files left if the origin server
12214 didn't send a Content-Length header and either the client has aborted
12215 transfer or bwrite() to client has failed. [Petr Lampa]
12217 *) Fixed the handling of module and script-added header fields.
12218 Improved the interface for sending header fields and reduced
12219 the duplication of code between sending okay responses and errors.
12220 We now always send both headers_out and err_headers_out, and
12221 ensure that the server-reserved fields are not being overridden,
12222 while not overriding those that are not reserved. [Roy Fielding]
12224 *) Moved transparent content negotiation fields to err_headers_out
12225 to reflect above changes. [Petr Lampa]
12227 *) Fixed the determination of whether or not we should make the
12228 connection persistent for all of the cases where some other part
12229 of the server has already indicated that we should not. Also
12230 improved the ordering of the test so that chunked encoding will
12231 be set whenever it is desired instead of only when KeepAlive
12232 is enabled. Added persistent connection capability for most error
12233 responses (those that do not indicate a bad input stream) when
12234 accessed by an HTTP/1.1 client. [Roy Fielding]
12236 *) Added missing timeouts for sending header fields, error responses,
12237 and the last chunk of chunked encoding, each of which could have
12238 resulted in a process being stuck in write forever. Using soft_timeout
12239 requires that the sender check for an aborted connection rather than
12240 continuing after an EINTR. Timeouts that used to be initiated before
12241 send_http_header (and never killed) are now initiated only within or
12242 around the routines that actually do the sending, and not allowed to
12243 propagate above the caller. [Roy Fielding]
12245 *) mod_auth_anon required an @ or a . in the email address, not both.
12248 *) per_dir_defaults weren't set correctly until directory_walk for
12249 name-based vhosts. This fixes an obscure bug with the wrong config
12250 info being used for vhosts that share the same ip as the server.
12253 *) Improved generation of modules/Makefile to be more generic for
12254 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
12256 *) Generate makefile dependency for Configuration based on the actual
12257 name given when running the Configure process. [Dean Gaudet]
12259 *) Fixed problem with vhost error log not being set prior to
12260 initializing virtual hosts. [Dean Gaudet]
12262 *) Fixed infinite loop when a trailing slash is included after a type map
12263 file URL (extra path info). [Petr Lampa]
12265 *) Fixed server status updating of per-connection counters. [Roy Fielding]
12267 *) Add documentation for DNS issues (reliability and security), and try
12268 to explain the virtual host matching process. [Dean Gaudet]
12270 *) Try to continue gracefully by disabling the vhost if a DNS lookup
12271 fails while parsing the configuration file. [Dean Gaudet]
12273 *) Improved calls to setsockopt. [Roy Fielding]
12275 *) Negotiation changes: Don't output empty content-type in variant list;
12276 Output charset in variant list; Return sooner from handle_multi() if
12277 no variants found; Add handling of '*' wildcard in Accept-Charset.
12278 [Petr Lampa and Paul Sutton]
12280 *) Fixed overlaying of request/sub-request notes and headers in
12281 mod_negotiation. [Dean Gaudet]
12283 *) If two variants' charset quality are equal and one is the default
12284 charset (iso-8859-1), then prefer the variant that was specifically
12285 listed in Accept-Charset instead of the default. [Petr Lampa]
12287 *) Memory allocation problem in push_array() -- it would corrupt memory
12288 when nalloc==0. [Kai Risku <krisku tf.hut.fi> and Roy Fielding]
12290 *) invoke_handler() doesn't handle mime arguments in content-type
12291 [Petr Lampa] PR#160
12293 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
12296 *) Fixed problem with ErrorDocument not working for virtual hosts
12297 due to one of the performance changes in 1.2b7. [Dean Gaudet]
12299 *) Log an error message if we get a request header that is too long,
12300 since it may indicate a buffer overflow attack. [Marc Slemko]
12302 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
12303 not reject URLs without a double-slash, as per RFC2068 section 3.2.
12304 [Ken Coar] PR #146, #187
12306 *) Added table entry placeholder for new header_parser callback
12307 in all of the distributed modules. [Ken Coar] PR #191
12309 *) Allow for cgi files without the .EXE extension on them under OS/2.
12310 [Garey Smiley] PR #59
12312 *) Fixed error message when resource is not found and URL contains
12313 path info. [Petr Lampa and Dean Gaudet] PR #40
12315 *) Fixed user and server confusion over what should be a virtual host
12316 and what is the main server, resulting in access to something
12317 other than the name defined in the virtualhost directive (but
12318 with the same IP address) failing. [Dean Gaudet]
12320 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
12321 AIX; improves the redirection stuff to enable the users to generally
12322 redirect to http, https, gopher and ftp; added TIME variable for
12323 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
12324 special patterns >STRING, <STRING and =STRING to RewriteCond, which
12325 can be used in conjunction with %{TIME} or other variables to create
12326 time-dependent rewriting rules. [Ralf S. Engelschall]
12328 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
12329 Module authors may need to adjust their code for proper cleanup to take
12330 place (that is, call note_cleanups_for_fd()). This change fixes problems
12331 with file descriptors being erroneously closed when the proxy module was
12332 in use. [Ben Laurie]
12334 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
12335 initgroups() to hose the group information needed for later
12336 comparisons. [Randy Terbush]
12338 *) Remove unnecessary call to va_end() in create_argv() which
12339 caused a SEGV on some systems.
12341 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
12344 *) Clear memory allocated for listeners. [Randy Terbush]
12346 *) Improved handling of IP address as a virtualhost address and
12347 introduced "_default_" as a synonym for the default vhost config.
12348 [Dean Gaudet] PR #212
12350 Changes with Apache 1.2b7
12352 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom yk.fujitsu.co.jp>]
12354 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
12356 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
12357 - replace protocol response numbers with symbols
12358 - save variant-list into main request notes
12359 - free allocated memory from subrequests
12360 - merge notes, headers_out and err_headers_out
12362 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
12363 "HTTP/#.# ###*" to be more lenient about what we accept.
12366 *) more proxy FTP bug fixes:
12367 - Changed send_dir() to remove user/passwd from displayed URL.
12368 - Changed login error messages to be more descriptive.
12369 - remove setting of SO_DEBUG socket option
12370 - Make ftp_getrc() more lenient about multiline responses,
12371 specifically, 230 responses which don't have continuation 230-
12372 on each line). These seem to be all NT FTP servers, and while
12373 perhaps questionable, they appear to be legal by RFC 959.
12374 - Add missing kill_timeout() after transfer to user completes.
12377 *) Fixed problem where a busy server could hang when restarting
12378 after being sent a SIGHUP due to child processes not exiting.
12381 *) Modify mod_include escaping so a '\' only signifies an escaped
12382 character if the next character is one that needs
12383 escaping. [Ben Laurie]
12385 *) Eliminated possible infinite loop in mod_imap when relative URLs are
12386 used with a 'base' directive that does not have a '/' in it.
12387 [Marc Slemko, reported by Onno Witvliet <onno tc.hsa.nl>]
12389 *) Reduced the default timeout from 1200 seconds to 300, and the
12390 one in the sample configfile from 400 to 300. [Marc Slemko]
12392 *) Stop vbprintf from crashing if given a NULL string pointer;
12393 print (null) instead. [Ken Coar]
12395 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
12396 [Marc Slemko and Roy Fielding]
12398 *) Fixed problem with mod_cgi-generated internal redirects trying to
12399 read the request message-body twice. [Archie Cobbs and Roy Fielding]
12401 *) Reduced timeout on lingering close, removed possibility of a blocked
12402 read causing the child to hang, and stopped logging of errors if
12403 the socket is not connected (reset by client). [Roy Fielding]
12405 *) Rearranged main child loop to remove duplication of code in
12406 select/accept and keep-alive requests, fixed several bugs regarding
12407 checking scoreboard_image for exit indication and failure to
12408 account for all success conditions and trap all error conditions,
12409 prevented multiple flushes before closing the socket; close the entire
12410 socket buffer instead of just one descriptor, prevent logging of
12411 EPROTO and ECONNABORTED on platforms where supported, and generally
12412 improved readability. [Roy Fielding]
12414 *) Extensive performance improvements. Cleaned up inefficient use of
12415 auto initializers, multiple is_matchexp calls on a static string,
12416 and excessive merging of response_code_strings. [Dean Gaudet]
12418 *) Added double-buffering to mod_include to improve performance on
12419 server-side includes. [Marc Slemko]
12421 *) Several fixes for suexec wrapper. [Randy Terbush]
12422 - Make wrapper work for files on NFS filesystem.
12423 - Fix portability problem of MAXPATHLEN.
12424 - Fix array overrun problem in clean_env().
12425 - Fix allocation of PATH environment variable
12427 *) Removed extraneous blank line is description of mod_status chars.
12430 *) Logging of errors from the call_exec routine simply went nowhere,
12431 since the logfile fd has been closed, so now we send them to stderr.
12432 [Harald T. Alvestrand]
12434 *) Fixed core dump when DocumentRoot is a CGI.
12435 [Ben Laurie, reported by <geddis tesserae.com>]
12437 *) Fixed potential file descriptor leak in mod_asis; updated it and
12438 http_core to use pfopen/pfclose instead of fopen/fclose.
12439 [Randy Terbush and Roy Fielding]
12441 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
12442 as the DEC Alpha which is 64-bit but uses 32-bit ints.
12443 [Dean Gaudet and Ken Coar]
12445 *) Return a 302 response code to the client when sending a redirect
12446 due to a missing trailing '/' on a directory instead of a 301; now
12447 it is cacheable. [Markus Gyger]
12449 *) Fix condition where, if a bad directive occurs in .htaccess, and
12450 sub_request() goes first to this directory, then log_reason() will
12451 SIGSEGV because it doesn't have initialized r->per_dir_config.
12452 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
12454 *) Fix handling of lang_index in is_variant_better(). This was
12455 causing problems which resulted in the server sending the
12456 wrong language document in some cases. [Petr Lampa]
12458 *) Remove free() from clean_env() in suexec wrapper. This was nuking
12459 the clean environment on some systems.
12461 *) Tweak byteserving code (e.g. serving PDF files) to work around
12462 bugs in Netscape Navigator and Microsoft Internet Explorer.
12463 Emit Content-Length header when sending multipart/byteranges.
12466 *) Port to HI-UX/WE2. [Nick Maclaren]
12468 *) Port to HP MPE operating system for HP 3000 machines
12469 [Mark Bixby <markb cccd.edu>]
12471 *) Fixed bug which caused a segmentation fault if only one argument
12472 given to RLimit* directives. [Ed Korthof]
12474 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
12476 *) Improved buffered output to the client by delaying the flush decision
12477 until the BUFF code is actually about to read the next request.
12478 This fixes a problem introduced in 1.2b5 with clients that send
12479 an extra CRLF after a POST request. Also improved chunked output
12480 performance by combining writes using writev() and removing as
12481 many bflush() calls as possible. NOTE: Platforms without writev()
12482 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
12483 or Configure, unless we have already done so. [Dean Gaudet]
12485 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
12487 *) Fixed mod_info output corruption bug introduced by buffer overflow
12488 fixes. [Dean Gaudet]
12490 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
12491 for the special case of a 304 response. [Paul Sutton]
12493 *) Improved handling of TRACE method by bypassing normal method handling
12494 and header parsing routines; fixed Allow response to always allow TRACE.
12497 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
12499 *) Cleaned-up some of the generated HTML. [Ken Coar]
12501 Changes with Apache 1.2b6
12503 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
12505 *) Fix typo introduced in fix for potential infinite loop around
12506 accept() in child_main(). This change caused the rev to 1.2b6.
12507 1.2b5 was never a public beta.
12509 Changes with Apache 1.2b5
12511 *) Change KeepAlive semantics (On|Off instead of a number), add
12512 MaxKeepAliveRequests directive. [Alexei Kosut]
12514 *) Various NeXT compilation patches, as well as a change in
12515 regex/regcomp.c since that file also used a NEXT define.
12518 *) Allow * to terminate the end of a directory match in mod_dir.
12519 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
12521 *) Don't call can_exec() if suexec_enabled. Calling this requires
12522 scripts executed by the suexec wrapper to be world executable, which
12523 defeats one of the advantages of running the wrapper. [Randy Terbush]
12525 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
12528 *) Migration from sprintf() to snprintf() to avoid buffer
12529 overflows. [Marc Slemko]
12531 *) Provide portable snprintf() implementation (ap_snprintf)
12532 as well as *cvt family. [Jim Jagielski]
12534 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
12537 *) Remove mod_fastcgi.c from the distribution. This module appears
12538 to be maintained more through the Open Market channels and should
12539 continue to be easily available at http://www.fastcgi.com/
12541 *) Fixed bug in modules/Makefile that wouldn't allow building in more
12542 than one subdirectory (or cleaning, either). [Jeremy Laidman]
12544 *) mod_info assumed that the config files were relative to ServerRoot.
12547 *) CGI scripts called as an error document resulting from failed
12548 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
12550 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
12553 *) Properly check errno to prevent display of a directory index
12554 when server receives a long enough URL to confuse stat().
12557 *) Several security enhancements to suexec wrapper. It is _highly_
12558 recommended that previously installed versions of the wrapper
12559 be replaced with this version. [Randy Terbush, Jason Dour]
12561 - ~user execution now properly restricted to ~user's home
12562 directory and below.
12563 - execution restricted to UID/GID > 100
12564 - restrict passed environment to known variables
12565 - call setgid() before initgroups() (portability fix)
12566 - remove use of setenv() (portability fix)
12568 *) Add HTTP/1.0 response forcing. [Ben Laurie]
12570 *) Add access control via environment variables. [Ben Laurie]
12572 *) Add rflush() function. [Alexei Kosut]
12574 *) remove duplicate pcalloc() call in new_connection().
12576 *) Fix incorrect comparison which could allow number of children =
12577 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
12578 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
12580 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
12581 AIX PS/2, CONVEXOS. [Jim Jagielski]
12583 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
12584 It's more portable. [Martin Kraemer]
12586 *) Replace references to make in Makefile.tmpl with $(MAKE).
12589 *) Add ProxyBlock directive w/IP address caching. Add IP address
12590 caching to NoCache directive as well. ProxyBlock works with all
12591 handlers; NoCache now also works with FTP for anonymous logins.
12592 Still more code cleanup. [Chuck Murcko]
12594 *) Add "header parse" API hook [Ben Laurie]
12596 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
12598 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
12600 *) Correctly allow access and auth directives in <Files> sections in
12601 server config files. [Alexei Kosut]
12603 *) Fix bug with ServerPath that could cause certain files to be not
12604 found by the server. [Alexei Kosut]
12606 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
12607 double-quote from text and so that it properly checks for unsupported
12608 status codes using the new index_of_response interface. [Roy Fielding]
12610 *) Multiple fixes to the lingering_close code in order to avoid being
12611 interrupted by a stray timeout, to avoid lingering on a connection
12612 that has already been aborted or never really existed, to ensure that
12613 we stop lingering as soon as any error condition is received, and to
12614 prevent being stuck indefinitely if the read blocks. Also improves
12615 reporting of error conditions. [Marc Slemko and Roy Fielding]
12617 *) Fixed initialization of parameter structure for sigaction.
12618 [<mgyger itr.ch>, Adrian Filipi-Martin]
12620 *) Fixed reinitializing the parameters before each call to accept and
12621 select, and removed potential for infinite loop in accept.
12622 [Roy Fielding, after useful PR from <adrian virginia.edu>]
12624 *) Fixed condition where, if a child fails to fork, the scoreboard would
12625 continue to say SERVER_STARTING forever. Eventually, the main process
12626 would refuse to start new children because count_idle_servers() will
12627 count those SERVER_STARTING entries and will always report that there
12628 are enough idle servers. [Phillip Vandry]
12630 *) Fixed bug in bcwrite regarding failure to account for partial writes.
12631 Avoided calling bflush() when the client is pipelining requests.
12632 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
12634 *) Added description of "." mode in server-status [Jim Jagielski]
12636 Changes with Apache 1.2b4
12638 *) Fix possible race condition in accept_mutex_init() that
12639 could leave a small security hole open allowing files to be
12640 overwritten in cases where the server UID has write permissions.
12643 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
12645 *) Fix portablity problem in util_script where ARG_MAX may not be
12646 defined for some systems.
12648 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
12651 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
12652 style magic #! token for better script portability. [Garey Smiley]
12654 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
12655 execution for ~userdir CGI. [Jason Dour]
12657 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
12659 *) Fix month off by one in suexec wrapper logging.
12661 Changes with Apache 1.2b3:
12663 *) Fix error in mod_cgi which could cause resources not to be properly
12664 freed, or worse. [Dean Gaudet]
12666 *) Fix find_string() NULL pointer dereference. [Howard Fear]
12668 *) Add set_flag_slot() at the request of Dirk and others.
12671 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
12673 *) Add changes to improve the error message given for invalid
12674 ServerName parameters. [Dirk vanGulik]
12676 *) Add "Authoritative" directive for Auth modules that don't
12677 currently have it. This gives admin control to assign authoritative
12678 control to an authentication scheme and allow "fall through" for
12679 those authentication modules that aren't "Authoritative" thereby
12680 allowing multiple authentication mechanisms to be chained.
12683 *) Remove requirement for ResourceConfig/AccessConfig if not using
12684 the three config file layout. [Randy Terbush]
12686 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
12688 *) Changes to suexec wrapper to fix the following problems:
12689 1. symlinked homedirs will kill ~userdirs.
12690 2. initgroups() on Linux 2.0.x clobbers gr->grid.
12691 3. CGI command lines paramters problems
12692 4. pw-pwdir for "docroot check" still the httpd user's pw record.
12693 [Randy Terbush, Jason Dour]
12695 *) Change create_argv() to accept variable arguments. This fixes
12696 a problem where arguments were not getting passed to the CGI via
12697 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
12699 *) Collapse multiple slashes in path URLs to properly apply
12700 handlers defined by <Location>. [Alexei Kosut]
12702 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
12704 *) Improve the accuracy of request duration timings by setting
12705 r->request_time in read_request_line() instead of read_request().
12708 *) Reset timeout while reading via get_client_block() in mod_cgi.c
12709 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
12711 *) Add the ability to pass different Makefile.tmpl files to Configure
12712 using the -make flag. [Rob Hartill]
12714 *) Fix coredump triggered when sending a SIGHUP to the server caused
12715 by an assertion failure, in turn caused by an uninitialised field in a
12719 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
12720 PATH_INFO from previous versions of Apache (in certain situations,
12721 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
12722 [later removed in 1.2b11]
12724 *) Add rwrite() function to API to allow for sending strings of
12725 arbitrary length. [Doug MacEachern]
12727 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
12729 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
12730 NeXT. [Jim Jagielski]
12732 *) Removed recent modification to promote the status code on internal
12733 redirects, since the correct fix was to change the default log format
12734 in mod_log_config so that it outputs the original status. [Rob Hartill]
12736 Changes with Apache 1.2b2:
12738 *) Update set_signals() to use sigaction() for setting handlers.
12739 This appears to fix a re-entrant problem in the seg_fault()
12740 bus_error() handlers. [Randy Terbush]
12742 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
12744 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
12746 *) proxy_http.c bugfixes: [Chuck Murcko]
12747 1) fixes possible NULL pointer reference w/NoCache
12748 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
12749 host would cache nothing if it was in the local domain,
12750 and the local domain was in the NoCache list)
12751 3) Adds Host: header when not available
12752 4) Some code cleanup and clarification
12754 *) mod_include.c bugfixes:
12755 1) Fixed an ommission that caused include variables to not
12756 be parsed in config errmsg directives [Howard Fear]
12757 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
12758 3) Patch to fix compiler warnings [<perrot lal.in2p3.fr>]
12759 4) Allow backslash-escaping to all quoted text
12760 [Ben Yoshino <ben wiliki.eng.hawaii.edu>]
12761 5) Pass variable to command line if not set in XSSI's env
12764 *) Fix infinite loop when processing Content-language lines in
12765 type-map files. [Alexei Kosut]
12767 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
12769 *) Fixed problem in set_[user|group] that prevented CGI execution
12770 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
12772 *) Added PORTING information file. [Jim Jagielski]
12774 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
12776 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
12778 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
12779 USE_FCNTL_SERIALIZED_ACCEPT was intended.
12781 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
12782 which caused problems of systems where socket s_addr is >32bits.
12784 *) Added comment to explain (r->chunked = 1) side-effect in
12785 http_protocol.c [Roy Fielding]
12787 *) Replaced use of index() in mod_expires.c with more appropriate
12788 and portable isdigit() test. [Ben Laurie]
12790 *) Updated Configure for ...
12791 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
12792 *-dg-dgux* (bad pattern match)
12793 QNX (DEF_WANTHSREGEX=yes)
12794 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
12796 *-unixware211 (new)
12797 and added some user diagnostic info. [Ben Laurie]
12799 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
12800 for better portability. [Jim Jagielski]
12802 *) Updated helpers/GuessOS for ...
12803 SCO 5 (recognize minor releases)
12804 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
12805 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
12806 IRIX64 (-sgi-irix64)
12807 ULTRIX (-unknown-ultrix)
12808 SINIX (-whatever-sysv4)
12809 NCR Unix (-ncr-sysv4)
12810 and fixed something in helpers/PrintPath [Ben Laurie]
12812 Changes with Apache 1.2b1
12814 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
12816 Changes with Apache 1.1.1
12818 *) Fixed bug where Cookie module would make two entries in the
12819 logfile for each access [Mark Cox]
12821 *) Fixed bug where Redirect in .htaccess files would cause memory
12822 leak. [Nathan Neulinger]
12824 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
12826 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
12828 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
12830 Changes with Apache 1.1.0
12832 *) Bring NeXT support up to date. [Takaaki Matsumoto]
12834 *) Bring QNX support up to date. [Ben Laurie]
12836 *) Make virtual hosts default to main server keepalive parameters.
12837 [Alexei Kosut, Ben Laurie]
12839 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
12841 *) Fix missing address family for connect, also remove unreachable statement
12842 in mod_proxy. [Ben Laurie]
12844 *) mod_env now turned on by default in Configuration.tmpl.
12846 *) Bugs which were fixed:
12847 a) yet more mod_proxy bugs [Ben Laurie]
12848 b) CGI works again with inetd [Alexei Kosut]
12849 c) Leading colons were stripped from passwords [<osm interguide.com>]
12850 d) Another fix to multi-method Limit problem [<jk tools.de>]
12852 Changes with Apache 1.1b4
12854 *) r->bytes_sent variable restored. [Robert Thau]
12856 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
12858 *) More possibly unsecure programs removed from the support directory.
12860 *) More mod_auth_msql authentication improvements.
12862 *) VirtualHosts based on Host: headers no longer conflict with the
12865 *) OS/2 compatibility enhancements. [Gary Smiley]
12867 *) POST now allowed to directory index CGI scripts.
12869 *) Actions now work with files of the default type.
12871 *) Bugs which were fixed:
12872 a) more mod_proxy bugs
12873 b) early termination of inetd requests
12874 c) compile warnings on several systems
12875 d) problems when scripts stop reading output early
12877 Changes with Apache 1.1b3
12879 *) Much of cgi-bin and all of cgi-src has been removed, due to
12880 various security holes found and that we could no longer support
12883 *) The "Set-Cookie" header is now special-cased to not merge multiple
12884 instances, since certain popular browsers can not handle multiple
12885 Set-Cookie instructions in a single header. [Paul Sutton]
12887 *) rprintf() added to buffer code, occurrences of sprintf removed.
12890 *) CONNECT method for proxy module, which means tunneling SSL should work.
12891 (No crypto needed) Also a NoCache config directive.
12893 *) Several API additions: pstrndup(), table_unset() and get_token()
12894 functions now available to modules.
12896 *) mod_imap fixups, in particular Location: headers are now complete
12899 *) New "info" module which reports on installed module set through a
12900 special URL, a la mod_status.
12902 *) "ServerPath" directive added - allows for graceful transition
12903 for Host:-header-based virtual hosts.
12905 *) Anonymous authentication module improvements.
12907 *) MSQL authentication module improvements.
12909 *) Status module design improved - output now table-based. [Ben Laurie]
12911 *) htdigest utility included for use with digest authentication
12914 *) mod_negotiation: Accept values with wildcards to be treated with
12915 less priority than those without wildcards at the same quality
12916 value. [Alexei Kosut]
12918 *) Bugs which were fixed:
12919 a) numerous mod_proxy bugs
12920 b) CGI early-termination bug [Ben Laurie]
12921 c) Keepalives not working with virtual hosts
12922 d) RefererIgnore problems
12923 e) closing fd's twice in mod_include (causing core dumps on
12924 Linux and elsewhere).
12926 Changes with Apache 1.1b2
12929 a) core dumps in mod_digest
12930 b) truncated hostnames/ip address in the logs
12931 c) relative URL's in mod_imap map files
12933 Changes with Apache 1.1b1
12935 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
12937 Changes with Apache 1.0.3
12939 *) Internal redirects which occur in mod_dir.c now preserve the
12940 query portion of a request (the bit after the question mark).
12943 *) Escape active characters '<', '>' and '&' in html output in
12944 directory listings, error messages and redirection links.
12947 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
12949 *) Fix for POSIX compliance in waiting for processes in alloc.c.
12952 *) setsockopt no longer takes a const declared argument [Martijn Koster]
12954 *) Reset timeout timer after each successful fwrite() to the network.
12955 This patch adds a reset_timeout() procedure that is called by
12956 send_fd() to reset the timeout ever time data is written to the net.
12959 *) timeout() signal handler now checks for SIGPIPE and reports
12960 lost connections in a more user friendly way. [Rob Hartill]
12962 *) Location of the "scoreboard" file which used to live in /tmp is
12963 now configurable (for OSes that can't use mmap) via ScoreBoardFile
12964 which works similar to PidFile (in httpd.conf) [Rob Hartill]
12966 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
12968 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
12969 which caused a SEGV with cookies enabled
12971 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
12974 *) Log the UNIX textual error returned by some system calls, in
12975 particular errors from accept() [David Robinson]
12977 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
12979 Changes with Apache 1.0.2
12981 *) patch to get Apache compiled on UnixWare 2.x, recommended as
12982 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
12984 *) Fix get_basic_auth_pw() to set the auth_type of the request.
12987 *) past changes to http_config.c to only use the
12988 setrlimit function on systems defining RLIMIT_NOFILE
12989 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
12990 for SUNOS and prototypes the needed functions.
12992 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
12995 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
12997 *) Merge multiple headers from CGI scripts instead of taking last
12998 one. [David Robinson]
13000 *) Add support for SCO 5. [Ben Laurie]
13002 Changes with Apache 1.0.1
13004 *) Silence mod_log_referer and mod_log_agent if not configured
13007 *) Recursive includes can occur if the client supplies PATH_INFO data
13008 and the server provider uses relative links; as file.html
13009 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
13011 *) The replacement for initgroups() did not call {set,end}grent(). This
13012 had two implications: if anything else used getgrent(), then
13013 initgroups() would fail, and it was consuming a file descriptor.
13016 *) On heavily loaded servers it was possible for the scoreboard to get
13017 out of sync with reality, as a result of a race condition.
13018 The observed symptoms are far more Apaches running than should
13019 be, and heavy system loads, generally followed by catastrophic
13020 system failure. [Ben Laurie]
13022 *) Fix typo in license. [David Robinson]
13024 Changes with Apache 1.0.0 23 Nov 1995
13026 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
13028 Changes with Apache 0.8.16 05 Nov 1995
13030 *) New man page for 'httpd' added to support directory [David Robinson]
13032 *) .htgroup files can have more than one line giving members for a
13033 given group (each must have the group name in front), for NCSA
13034 back-compatibility [Robert Thau]
13036 *) Mutual exclusion around accept() is on by default for SVR4 systems
13037 generally, since they generally can't handle multiple processes in
13038 accept() on the same socket. This should cure flaky behavior on
13039 a lot of those systems. [David Robinson]
13041 *) AddType, AddEncoding, and AddLanguage directives take multiple
13042 extensions on a single command line [David Robinson]
13044 *) UserDir can be disabled for a given virtual host by saying
13045 "UserDir disabled" in the <VirtualHost> section --- it was a bug
13046 that this didn't work. [David Robinson]
13048 *) Compiles on QNX [Ben Laurie]
13050 *) Corrected parsing of ctime time format [David Robinson]
13052 *) httpd does a perror() before exiting if it can't log its pid
13053 to the PidFile, to make diagnosing the error a bit easier.
13056 *) <!--#include file="..."--> can no longer include files in the
13057 parent directory, for NCSA back-compatibility. [David Robinson]
13059 *) '~' is *not* escaped in URIs generated for directory listings
13062 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
13064 *) Fixed bug involving handling URIs with escaped %-characters
13065 in redirects [David Robinson]
13067 Changes with Apache 0.8.15 14 Oct 1995
13069 *) Switched to new, simpler license
13071 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
13073 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
13075 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
13077 *) Correctly handles internal redirects to files with names containing '%'
13080 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
13082 *) Use geteuid() rather than getuid() to see if we have root privilege,
13083 so that server correctly resets privilege if run setuid root. [Andrew
13086 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
13089 *) Fix relative URLs in imagemap files [Randy Terbush]
13091 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
13094 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
13095 entries all name the same one. [David Robinson]
13097 *) Fix directory listings with filenames containing unusual characters
13100 *) Better URI-escaping for generated URIs in directories with filenames
13101 containing unusual characters [Ben Laurie]
13103 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
13105 *) Unblock alarms on error return from spawn_child() [David Robinson]
13107 *) Sample Config files have extra note for SCO users [Ben Laurie]
13109 *) Configuration has note for HP-UX users [Rob Hartill]
13111 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
13113 *) Nuked bogus #define in httpd.h [David Robinson]
13115 *) Better test for whether a system has setrlimit() [David Robinson]
13117 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
13119 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
13122 Changes with Apache 0.8.14 19 Sep 1995
13124 *) Compiles on SCO ODT 3.0 [Ben Laurie]
13126 *) AddDescription works (better) [Ben Laurie]
13128 *) Leaves an intelligible error diagnostic when it can't set group
13129 privileges on standalone startup [Andrew Wilson]
13131 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
13132 that machine, which claims to be BSD but does not support RLIMIT.
13135 *) gcc -Wall no longer complains about an unused variable when util.c
13136 is compiled with -DMINIMAL_DNS [Andrew Wilson]
13138 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
13140 Changes with Apache 0.8.13 07 Sep 1995
13142 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
13144 *) Have built-in imagemap code recognize & honor Point directive [James
13147 *) Generate cleaner directory listings in directories with a mix of
13148 long and short filenames [Rob Hartill]
13150 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
13152 *) Properly default ServerName for virtual servers [Robert Thau]
13154 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
13155 Paul Richards and a cast of thousands...]
13157 *) On self-identified BSD systems (we don't try to guess any more),
13158 allocate a few extra file descriptors per virtual host with setrlimit,
13159 if we can, to avoid running out. [Randy Terbush]
13161 *) Write 22-character lock file name into buffer with enough space
13162 on startup [Konstantin Olchanski]
13164 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
13167 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
13169 *) Suppress -Wall warning by initializing variable in negotiation code
13170 [Tobias Weingartner]
13172 Changes with Apache 0.8.12 31 Aug 1995
13174 *) Doesn't pause three seconds after including a CGI script which is
13175 too slow to die off (this is done by not even trying to kill off
13176 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
13177 after the entire document has been processed). [Robert Thau]
13179 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
13181 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
13183 *) Allows .htaccess files to override <Directory> sections naming the
13184 same directory [David Robinson]
13186 *) Removed an efficiency hack in sub_req_lookup_uri which was
13187 causing certain extremely marginal cases (e.g., ScriptAlias of a
13188 *particular* index.html file) to fail. [David Robinson]
13190 *) Doesn't log an error when the requested URI requires
13191 authentication, but no auth header line was supplied by the
13192 client; this is a normal condition (the client doesn't no auth is
13193 needed here yet). [Robert Thau]
13195 *) Behaves more sanely when the name server loses its mind [Sean Welch]
13197 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
13199 *) RFC931 code no longer passes out name of prior clients on current
13200 requests if the current request came from a server that doesn't
13201 do RFC931. [David Robinson]
13203 *) Configuration script accepts "Module" lines with trailing whitespace.
13206 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
13208 *) Cleaned up comments in mod_cgi.c [Robert Thau]
13210 Changes with Apache 0.8.11 24 Aug 1995
13212 *) Wildcard <Directory> specifications work. [Robert Thau]
13214 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
13216 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
13217 the file being requested itself, in addition to the directories leading
13218 up to it. [Robert Thau]
13220 *) Logs access failures due to symlink checks or invalid client address
13221 in the error log [Roy Fielding, Robert Thau]
13223 *) Symlink checks deal correctly with systems where lstat of
13224 "/path/to/some/link/" follows the link. [Thau, Fielding]
13226 *) Doesn't reset DirectoryIndex to 'index.html' when
13227 other directory options are set in a .htaccess file. [Robert Thau]
13229 *) Clarified init code and nuked bogus warning in mod_access.c
13230 [Florent Guillaume]
13232 *) Corrected several directives in sample srm.conf
13233 --- includes corrections to directory indexing icon-related directives
13234 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
13235 icons for encodings right, and turning on AddEncoding by default).
13238 *) Corrected descriptions of args to AddIcon and AddAlt in command table
13241 *) INSTALL & README mention "contributed modules" directory [Brian
13244 *) Fixed English in the license language... "for for" --> "for".
13247 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
13248 mod_alias.c, merging it almost completely with handling of Alias, and
13249 adding a 'notes' field to the request_rec which allows the CGI module
13250 to discover whether the Alias module has put this request through
13251 ScriptAlias (which it needs to know for back-compatibility, as the old
13252 NCSA code did not check Options ExecCGI in ScriptAlias directories).
13255 Changes with Apache 0.8.10 18 Aug 1995
13257 *) AllowOverride applies to the named directory, and not just
13258 subdirectories. [David Robinson]
13260 *) Do locking for accept() exclusion (on systems that need it)
13261 using a special file created for the purpose in /usr/tmp, and
13262 not the error log; using the error log causes real problems
13263 if it's NFS-mounted; this is known to be the cause of a whole
13264 lot of "server hang" problems with Solaris. [David Robinson;
13265 thanks to Merten Schumann for help diagnosing the problem].
13267 Changes with Apache 0.8.9 12 Aug 1995
13269 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
13271 *) Nested includes see environment variables of the including document,
13272 for NCSA bug-compatibility (some sites have standard footer includes
13273 which try to print out the last-modified date). [Eric Hagberg/Robert
13276 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
13277 URI as a CGI script, even if it would have been treated as something
13278 else if requested directly, for NCSA back-compatibility. (Note that
13279 this means that people who know the name of the script can see the
13280 code just by asking for it). [Robert Thau]
13282 *) New version of dbmmanage script included in support directory as
13285 *) Check if scoreboard file couldn't be opened, and say so, rather
13286 then going insane [David Robinson]
13288 *) POST to CGI works on A/UX [Jim Jagielski]
13290 *) AddIcon and AddAlt commands work properly [Rob Hartill]
13292 *) NCSA server push works properly --- the Arena bug compatibility
13293 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
13294 if you still want the workaround). [Rob Hartill]
13296 *) If client didn't submit any Accept-encodings, ignore encodings in
13297 content negotiation. (NB this will all have to be reworked anyway
13298 for the new HTTP draft). [Florent Guillaume]
13300 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
13302 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
13304 *) Give Redirect priority over Alias, for NCSA bug compatibility
13307 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
13308 paralleling earlier bug fix for CGI [David Robinson]
13310 *) If DBM auth is improperly configured, report a server error and don't
13313 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
13314 it seems to work well enough without it (even in a 10 hits/sec
13315 workout), and the overhead for the locking under A/UX is
13316 alarmingly high (though it is very low on other systems).
13317 [Eric Hagberg, Jim Jagielski]
13319 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
13321 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
13322 Behlendorf/Eric Hagberg]
13324 *) More improvements to default Configuration for A/UX [Jim Jagielski]
13326 *) Compiles clean on NEXT [Rob Hartill]
13328 *) Compiles clean on SGI [Robert Thau]
13330 Changes with Apache 0.8.8 08 Aug 1995
13332 *) SunOS library prototypes now never included unless explicitly
13333 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
13334 people using GNU libc on SunOS are screwed by prototypes for the
13337 (Those who wish to compile clean with gcc -Wall on a standard
13338 SunOS setup need the prototypes, and may obtain them using
13339 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
13340 with nonstandard libraries are presumably competent to make their
13343 *) Strips trailing '/' characters off both args to the Alias command,
13344 to make 'Alias /foo/ /bar/' work.
13346 Changes with Apache 0.8.7 03 Aug 1995
13348 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
13349 [reported by David Robinson]
13351 *) Compiles clean on OSF/1 [David Robinson]
13353 *) Added some of the more recent significant changes (AddLanguage stuff,
13354 experimental LogFormat support) to CHANGES file in distribution root
13357 Changes with Apache 0.8.6 02 Aug 1995
13359 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
13360 (If you actually wanted a conditional GET which bypassed the cache, you
13361 couldn't get it). [Reported by Roy Fielding]
13363 *) Properly terminate headers on '304 Not Modified' replies to conditional
13364 GETs --- no browser we can find cares much, but the CERN proxy chokes.
13365 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
13367 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
13369 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
13370 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
13371 and older versions don't set the __SUNPRO_C preprocessor variable). On
13372 all other systems, these are never used anyway. [Reported by Mark Cox].
13374 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
13376 Changes with Apache 0.8.5 01 Aug 1995
13378 *) Added last-minute configurable log experiment, as optional module
13380 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
13381 properly. (One-line fix to http_protocol.c).
13383 *) Work around bogus behavior when reloading from Netscape.
13384 It's Netscape's bug --- for some reason they expect a request with
13385 If-modified-since: to not function as a conditional GET if it also
13386 comes with Pragma: no-cache, which is way out of line with the HTTP
13387 spec (according to Roy Fielding, the redactor).
13389 *) Added parameter to set maximum number of server processes.
13391 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
13394 *) IdentityCheck bugfix [Chuck Murcko].
13396 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
13398 *) More sample config file corrections; add extension to AddType for
13399 *.asis, move AddType generic description to its proper place, and
13400 fix miscellaneous typos. [ Alexei Kosut ]
13402 *) Deleted the *other* reference to the regents from the Berkeley
13403 legal disclaimer (everyplace).
13405 *) Nuked Shambhala name from src/README; had already cleaned it out
13406 of everywhere else.
13408 Changes with Apache 0.8.4
13410 *) Changes to server-pool management parms --- renamed current
13411 StartServers to MinSpareServers, created separate StartServers
13412 parameter which means what it says, and renamed MaxServers to
13413 MaxSpareServers (though the old name still works, for NCSA 1.4
13414 back-compatibility). The old names were generally regarded as
13415 too confusing. Also altered "docs" in sample config files.
13417 *) More improvements to default config files ---
13418 sample directives (commented out) for XBitHack, BindAddress,
13419 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
13420 defaults, AddTypes for send-as-is and imagemap magic types, and
13421 improvements to samples for DirectoryIndex [Alexei Kosut]
13423 *) Yet more improvements to default config files --- changes to
13424 Alexei's sample AddLanguage directives, and sample LanguagePriority
13425 [ Florent Guillaume ]
13427 *) Set config file locations properly if not set in httpd.conf
13430 *) Don't escape URIs in internal redirects multiple times; don't
13431 do that when translating PATH_INFO to PATH_TRANSLATED either.
13434 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
13436 Changes with Apache 0.8.3
13438 *) Edited distribution README to *briefly* summarize installation
13439 procedures, and give a pointer to the INSTALL file in the src/
13442 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
13443 recent NCSA distributions.
13445 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
13446 exist for the same directory, use both and don't segfault. [Reported
13449 *) Proper makefile dependencies [David Robinson]
13451 *) Note (re)starts in error log --- reported by Rob Hartill.
13453 *) Only call no2slash() after get_path_info() has been done, to
13454 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
13455 reported by Andrew Wilson, though this one is probably a real bug]
13457 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
13458 dump core when Referer is not supplied. [Randy Terbush]
13460 *) Lightly edited sample config files to refer people to our documentation
13461 instead of NCSA's, and to list Rob McCool as *original* author (also
13462 deleted his old, and no doubt non-functional email address). Would be
13463 nice to have examples of new features...
13465 Changes with Apache 0.8.2 19 Jul 1995
13467 *) Added AddLanuage code [Florent Guillaume]
13469 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
13471 *) All sorts of problems when MultiViews finds a directory. It would
13472 be nice if mod_dir.c was robust enough to handle that, but for now,
13473 just punt. [reported by Brian Behlendorf]
13475 *) Wait for all children on restart, to make sure that the old socket
13476 is gone and we can reopen it. [reported by Randy Terbush]
13478 *) Imagemap module is enabled in default Configuration
13480 *) RefererLog and UserAgentLog modules properly default the logfile
13483 *) Mark Cox's mod_cookies added to the distribution as an optional
13484 module (commented out in the default Configuration, and noted as
13485 an experiment, along with mod_dld). [Mark Cox]
13487 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
13489 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
13491 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
13493 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
13496 Changes with Apache 0.8.1
13498 *) New imagemap module [Randy Terbush]
13500 *) Replacement referer log module with NCSA-compatible RefererIgnore
13501 [Matthew Gray again]
13503 *) Don't mung directory listings with very long filenames.
13504 [Florent Guillaume]
13506 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
13508 *) New config script. See INSTALL for info. [Robert Thau]
13510 *) Scoreboard mechanism for regulating the number of extant server
13511 processes. MaxServers and StartServers defaults are the same as
13512 for NCSA, but the meanings are slightly different. (Actually,
13513 I should probably lower the MaxServers default to 10).
13515 Before asking for a new connection, each server process checks
13516 the number of other servers which are also waiting for a
13517 connection. If there are more than MaxServers, it quietly dies
13518 off. Conversely, every second, the root, or caretaker, process
13519 looks to see how many servers are waiting for a new connection;
13520 if there are fewer than StartServers, it starts a new one. This
13521 does not depend on the number of server processes already extant.
13522 The accounting is arranged through a "scoreboard" file, named
13523 /tmp/htstatus.*, on which each process has an independent file
13524 descriptor (they need to seek without interference).
13526 The end effect is that MaxServers is the maximum number of
13527 servers on an *inactive* server machine, but more will be forked
13528 off to handle unusually heavy loads (or unusually slow clients);
13529 these will die off when they are no longer needed --- without
13530 reverting to the overhead of full forking operation. There is a
13531 hard maximum of 150 server processes compiled in, largely to
13532 avoid forking out of control and dragging the machine down.
13533 (This is arguably too high).
13535 In my server endurance tests, this mechanism did not appear to
13536 impose any significant overhead, even after I forced it to put the
13537 scoreboard file on a normal filesystem (which might have more
13538 overhead than tmpfs). [Robert Thau]
13540 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
13543 *) Read .htaccess files even in directory with <Directory> section.
13544 (Former incompatibility noted on mailing list, now fixed). [Robert
13547 *) "HEAD /" gives the client a "Bad Request" error message, rather
13548 than trying to send no body *and* no headers. [Cliff Skolnick].
13550 *) Don't produce double error reports for some very obscure cases
13551 mainly involving auth configuration (the "all modules decline to
13552 handle" case which is a sure sign of a server bug in most cases,
13553 but also happens when authentication is badly misconfigured).
13556 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
13557 it's *for*, and this sort of thing really shouldn't be cluttering
13558 up the Makefile). [Robert Thau]
13560 *) Incidental code cleanups in http_main.c --- stop dragging
13561 sa_client around; just declare it where used. [Robert Thau]
13563 *) Another acc-related fix. (It doesn't like const char
13564 in some places...). [Mark Cox]
13566 Changes with Shambhala 0.6.1 13 Jul 1995
13568 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
13569 Also, fixed auth typo in http_protocol.c unmasked by this fix.
13571 *) Compiles clean with acc on SunOS [Paul Sutton]
13573 *) Reordered modules in modules.c so that Redirect takes priority
13574 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
13575 believe it or not, he has an actual site with a ScriptAlias and
13576 a Redirect declared for the *exact same directory*. Even *my*
13577 compatibility fetish wouldn't motivate me to fix this if the fix
13578 required any effort, but it doesn't, so what the hey.
13580 *) Fixed to properly default several server_rec fields for virtual
13581 servers from the corresponding fields in the main server_rec.
13582 [Cliff Skolnick --- 'port' was a particular irritant].
13584 *) No longer kills off nph- child processes before they are
13585 finished sending output. [Matthew Gray]
13587 Changes with Shambhala 0.6.0 10 Jul 1995
13589 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
13590 the connection to the client in an "aborted" state, but otherwise
13591 allow whatever handlers are running to clean up. hard_timeout()s
13592 abort the request in progress completely; anything not tied to some
13593 resource pool cleanup will leak. They're still around because I
13594 haven't yet come up with a more elegant way of handling
13595 timeouts when talking to something that isn't the client. The
13596 default_handler and the dir_handler now use soft timeouts, largely
13597 so I can test the feature. [Robert Thau]
13599 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
13600 the case of log handlers dying prematurely is probably handled VERY
13601 gracelessly at this point, and if the logger stops reading input,
13602 the server will hang. (It is known to correctly restart the
13603 logging process on server restart; this is (should be!) going through
13604 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
13605 script). [Robert Thau]
13607 *) asis files supported (new module). [Robert Thau]
13609 *) IdentityCheck code is compiled in, but has not been tested. (I
13610 don't know anyone who runs identd). [Robert Thau]
13612 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
13613 came in with the request, for NCSA bug-compatibility. [Robert Thau]
13615 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
13617 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
13618 as timeouts are not in scope. [Robert Thau]
13620 *) quoted-string args in config files now handled correctly (doesn't drop
13621 the last character). [Robert Thau; reported by Randy Terbush]
13623 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
13624 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
13626 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
13627 default default type); the former default default behavior when all
13628 type-checkers defaulted had been a core dump. [Paul Sutton]
13630 *) Copy filenames out of the struct dirent when indexing
13631 directories. (On Linux, readdir() returns a pointer to the same
13632 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
13634 Changes with Shambhala 0.5.3 [not released]
13636 *) Default response handler notes "file not found" in the error log,
13637 if the file was not found. [Cliff Skolnick].
13639 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
13640 code no longer sets up bogus PATH_INFO which fakes out the directory
13641 handler). [Cliff Skolnick]
13643 Changes with Shambhala 0.5.2 06 Jul 1995
13645 *) Changes to http_main.c --- root server no longer plays silly
13646 games with SIGCHLD, and so now detects and replaces dying
13647 children. Child processes just die on SIGTERM, without taking
13648 the whole process group with them. Potential problem --- if any
13649 child process refuses to die, we hang in restart.
13650 MaxRequestsPerChild may still not work, but it certainly works
13651 better than it did before this! [Robert Thau]
13653 *) mod_dir.c bug fixes: ReadmeName and HeaderName
13654 work (or work better, at least); over-long description lines
13655 properly terminated. [Mark Cox]
13657 *) http_request.c now calls unescape_url() more places where it
13658 should [Paul Sutton].
13660 *) More directory handling bugs (reported by Cox)
13661 Parent Directory link is now set correctly. [Robert Thau]
13663 Changes with Shambhala 0.5.1 04 Jul 1995
13665 *) Generalized cleanup interface in alloc.c --- any function can be
13666 registered with alloc.c as a cleanup for a resource pool;
13667 tracking of files and file descriptors has been reimplemented in
13668 terms of this interface, so I can give it some sort of a test.
13671 *) More changes in alloc.c --- new cleanup_for_exec() function,
13672 which tracks down and closes all file descriptors which have been
13673 registered with the alloc.c machinery before the server exec()s a
13674 child process for CGI or <!--#exec-->. CGI children now get
13675 started with exactly three file descriptors open. Hopefully,
13676 this cures the problem Rob H. was having with overly persistent
13677 CGI connections. [Robert Thau]
13679 *) Mutual exclusion around the accept() in child_main() --- this is
13680 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
13681 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
13682 This uses fcntl(F_SETLK,...) on the error log descriptor because
13683 flock() on that descriptor won't work on systems which have BSD
13684 flock() semantics, including (I think) Linux 1.3 and Solaris.
13686 This does work on SunOS (when the server is idle, only one
13687 process in the pool is waiting on accept()); it *ought* to work
13688 on the other systems. [Robert Thau]
13690 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
13692 *) sizeof(*sa_client) bugfix from [Rob Hartill]
13694 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
13696 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
13697 be unnecessary if I go to the revised timeout-handling scheme).
13700 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
13701 string) even if none came in with the request. [Robert Thau]
13703 *) CHANGES file added to distribution ;-).
13705 Changes with Shambhala 0.4.5
13707 *) mod_dld --- early dynamic loading support [rst]
13708 *) Add wildcard content handlers for XBITHACK; default_hander now
13709 invoked with that mechanism (as a handler hanging off mod_core) [rst]
13710 *) XBITHACK supported as a wildcard content-handler, and
13711 configurable at run-time (not just at compile time, as in the
13712 "patchy server" releases) [rst]
13714 Changes with Shambhala 0.4.4 30 Jun 1995
13716 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
13717 *) Handle Addtype x/y .z [rst, reported by Cox]
13719 Changes with Shambhala 0.4.3
13721 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
13722 synonymous [rst, terbush]
13724 Changes with Shambhala 0.4.1 28 Jun 1995
13726 *) First-cut virtual host implementation; some refit in the config
13727 reading code, and log management, was necessary to support this [rst]
13728 *) Sub-pool machinery, originally added to avoid excessive storage
13729 allocation on listings of large directories (which turned out to
13730 be the problem that the 0.3 storage accounting was added to
13731 find). Subrequests and mod_dir changed to use subpools. [rst]
13732 *) More memory debugging --- free list consistency checks. [rst]
13733 *) Added err_headers to request_rec, with support elsewhere [rst]
13734 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
13736 Changes with Shambhala 0.3 19 Jun 1995
13738 *) Switch ONE_PROCESS to a runtime command-line option (-X)
13739 *) Don't compile in mod_ai_backcompat by default
13740 *) Switch name of server from Apache to Shambhala in Makefile
13741 *) Add some accounting routines to track memory usage in the pools,
13744 Changes with Shambhala 0.2
13746 *) Set DOCUMENT_ROOT CGI variable
13747 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
13748 *) Add critical section protection to handling of cleanup structures
13750 *) Significant code reorg within the server core to group related
13751 functions together [rst]
13752 *) Correctly handle clients that hang up before sending any request
13754 *) Replace dying child processes. [rst]
13756 Changes with Shambhala 0.1 12 Jun 1995
13758 Major rewrite of the pre-existing "patchy server" codebase, by
13759 Robert Thau (rst). Significant portions of the server code, such
13760 as configuration-file handling and HTTP authentication support,
13761 were ripped out and rewritten from scratch. Code that was not
13762 completely rewritten was significantly altered.
13764 Major changes with this release include:
13766 *) Introduction of the module API; in request handling, the central
13767 machinery just dispatches to various modules, which actually do
13768 most of the work. Configuration handling is similar --- modules
13769 declare their own commands, and the central machinery just
13770 dispatches to them.
13772 API features from shambhala/0.1 were substantially unchanged in
13773 Apache 1.0 and 1.1. (1.0 API features not yet present in this
13774 release, such as wildcard handlers and subpools, were added in
13775 subsequent Shambhala releases, and were also generally rst's
13778 *) This release included the following modules:
13780 mod_access (access control --- allow and deny directives),
13781 mod_alias (Alias and Redirect commands),
13782 mod_auth (straight HTTP authentication, based on flat-files)
13783 mod_auth_dbm (same, with dbm files)
13784 mod_cgi (CGI scripts and, in this release, ScriptAlias)
13785 mod_common_log (CLF access logs; later renamed mod_log_common)
13786 mod_dir (directory indexing)
13787 mod_include (server-side includes)
13788 mod_mime (AddType directives)
13789 mod_negotiation (content negotiation)
13790 mod_userdir (support for users' public_html directories)
13792 It also included a mod_ai_backcompat, which was a private hack
13793 for back-compatibility with rst's own AI-lab servers.
13795 All of these modules were substantially complete, and functional
13796 or nearly so (a few, which implemented features not in use at
13797 Thau's site, required patches of a few lines).
13799 *) sub-request machinery, to allow modules to determine how other
13800 modules would assign MIME types to a given file, or optionally
13801 serve its content (this is heavily used by mod_dir, mod_include
13802 and mod_negotiation).
13804 *) Resource pool system for keeping track of memory allocated and
13805 files opened in service of a particular request. Much of the
13806 code in the modules (when they weren't rewrites) was adjusted to
13807 replace a pervasive convention of using fixed-size buffers on
13808 the stack with an equally pervasive convention of using memory
13809 allocated with palloc().
13811 *) Reorganization of data structures associated with a given
13812 request to eliminate use of global variables and the troublesome
13813 unmunge_name function (used in NCSA and early Apache releases to
13814 attempt to determine the URI which mapped to a given filename
13815 --- a difficult proposition, given that it is easy to produce
13816 setups in which multiple URIs map to the same file).
13818 *) Source files renamed and rearranged
13820 *) Very simple pre-forking behavior --- parent process forked off a
13821 fixed number of children, and then just waited for SIGHUP.
13823 *) Other more minor changes too numerous to list.
13825 This release included modified versions of a lot of code from the
13826 Apache 0.6.4 public release, plus an early pre-forking patch
13827 codeveloped by Robert Thau and Rob Hartill.
13829 Changes with Apache 0.7.3 20 Jun 1995
13831 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
13832 were incorporated by Rob Hartill on the main branch while Robert Thau
13833 worked on the Shambhala rewrite above. Most were merged into the
13834 Shambala architecture after Apache 0.8.0.
13836 Changes with Apache 0.6.4 13 May 1995
13838 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
13841 Changes with Apache 0.5.1 10 Apr 1995
13843 Changes with Apache 0.4 02 Apr 1995
13845 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
13848 Changes with Apache 0.3 24 Mar 1995
13850 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
13853 Changes with Apache 0.2 18 Mar 1995
13855 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
13856 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
13857 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
